The Adverse Effects of Underwater Sound upon Fishes and Invertebrates

Feb 2023 DOI 10.14302/issn.2643-0282.imsj-22-4314
D Hawkins AnthonyCorresponding author

Underwater sound is very important to most fishes and invertebrates. Underwater sounds from both natural and human sources can have adverse effects upon aquatic animals, and especially fishes, and invertebrates. It is important to examine the effects of sound upon them, and especially the effects of sounds derived from human sources (anthropogenic sounds). It may be possible to introduce protective regulations to reduce their effects. Fishes and invertebrates can detect underwater sounds, and they use sound to obtain key information about the environment around them. They can also make sounds themselves, especially during their spawning. Sounds travel rapidly over great distances in water and can provide detailed information to these animals on the presence of prey, predators, and related species, while the overall acoustic scene provides them with key information about their environment. Anthropogenic sounds can be very harmful, and it is therefore important to deal with them. A succession of reports and scientific papers have emphasised the risks to these animals from exposure to man-made sounds or noise and will be mentioned in this paper, which also deals with the Criteria and Metrics for assessing the effects of underwater sound on fishes and invertebrates.

Elie NKWABONGCorresponding author Department of Obstetrics & Gynecology; University Teaching Hospital/ Faculty of Medicine and Biomedical Sciences, Yaoundé (Cameroon).

Objectives: To identify the lowest hemoglobin concentration (Hb) associated with increased risk of materno-fetal complications. Material and methods: This cohort study was conducted in the Yaoundé University Teaching Hospital, Cameroon, from March 1st, 2011 to February 28th, 2013. Maternal and fetal outcomes among anemic women (AW) and non-anemic women (NW) were compared. Two hundred and twelve AW (booking Hb <10g/dl) without any chronic diseases, carrying singletons and 212 similar NW (Hb ≥11g/dl) were followed up. Main variables were booking and 36 weeks Hb, complications observed and birth weight (BW). Data were analyzed using SPSS 18.0. Fisher exact test and t-test were used for comparison. Level of significance was P<0.05. Results: Mean booking Hb was 8.9 ± 1.1 g/dl among AW against 11.7 ± 0.6 g/dl among NW (P<0.001). Complications of anemia in pregnancy in our series (low BW (RR 7, 95%CI 1.6-30.4), pre-eclampsia (RR 3.3, 95%CI 0.9-11.9) and premature delivery (RR 3, 95%CI 0.6-14.6)) occurred frequently when mean 36 weeks Hb was <9g/dl. Conclusion: Complications were significantly observed when mean Hb was persistently <9g/dl.

Efficacy of Neemraj and Beauvitech on Abundance and Distribution of Arthropod Pests in Soil and Hydroponically Grown Strawberry

G.W MbauCorresponding author

Strawberry is a commercially important crop which has gained global significance in terms of production and consumption. The strawberry farmers have been faced with economic losses due to attack from arthropod and phytophagus pests. To overcome this challenge, management of pests is important with reduced impact on beneficial organisms and the environment. Use of non-chemical approaches as an alternative to insecticide driven management is highly gaining popularity. Identification of the non-chemical production for management of strawberry pest such as entomopathogenic fungi and botanicals is critical. The need for compatibility of entomopathogenic fungi in crop production techniques with other insecticides to enhance efficacy is required. The interaction between these control agents could be synergistic, additive or even antagonistic. Synergistic interactions usually lead to enhanced effectiveness of the microbial control agents while reducing the adverse effects of the pesticides in combination. In this review a description of the compatibility of entomopathogenic fungus Beauvaria bassiana and botanical neem in strawberry pest management is given. The experiment involved five treatments: Neemraj, Beauvitech, Neemraj and Beauvitech, Ampligo and control. These treatments were allocated in a completely Randomized design in two separate greenhouse setups one with soil and other with pumice. The treatments were replicated four times. The data was subjected to analysis of variance (ANOVA) using the general linear model (GLM) procedure of the statistical analysis system (SAS) program, version 9.1. Tukey’s (HSD) test at P≤ 0.05 was used to separate significant means. The combination of Neemraj and Beauvitech was most effective in the management of pests in both hydroponics and soil grown media. Pest populations were reduced significantly as follows; thrips, Frankliniella spp 2.1, red spider mites Tetranychus species 11.5, tarnished plant bug Lygus species 3.0, there was 0% cricket Gryllus species damage and 0 number strawberry weevil in hydroponics cultures while in soil culture pest mean populations were: thrips 5.6, spider mites Tetranychus species 18.2, strawberry weevil (Otiorhynchus species) 7.0, tarnished plant bug 3.0 and there was 13.8% cricket Gryllus species damage on strawberry plants.

Impact of Climate Change on Public Health in Rwanda

Sep 2024 DOI 10.14302/issn.3070-3379.jwc-24-5199
Fidele NizeyimanaCorresponding author

Rwanda is a small Central African country. A land with thousands of hills and mountains. It is a low-income country and one of Africa's fastest-growing economies. It is home to a variety of ecosystems, such as mountainous rainforests, gallery forests, savanna woodlands, wetlands, aquatic forests, and agroecosystems. From rising temperatures to changing rainfall patterns, the hidden dangers of climate change are unmasking themselves in the form of various health risks. Every year, many deaths, bodily injuries, and house collapses, among other repercussions, are documented as detrimental effects of climate change events on public health. This article delves into the intricate relationship between climate change and public health in Rwanda, exploring the adverse effects it has on vulnerable communities. By shedding light on this pressing issue, we can better understand the urgency of taking action to mitigate the impact of climate change on public health as well as potential solutions to the current predicament. The authors researched several literatures to develop their perspectives on the subject and explored potential solutions to protect the well-being of Rwandans in the face of this global crisis.

A Cross Sectional Analysis of Frailty and Markers of Frailty in Young People Living with HIV/AIDS

Jul 2024 DOI 10.14302/issn.2641-4538.jphi-24-5017
V K SashindranCorresponding author

Background Frailty is an ageing-associated state linked to poor prognostic outcomes. Chronic inflammation due to HIV-infection, AIDS-related infections. and the adverse effects of antiretroviral therapy (ART) all contribute to frailty in people living with HIV/AIDS (PLHA). Frailty has been comprehensively studied in populations comprising predominantly of Caucasian PLHA. However, there remains a dearth of such data in Indian populations, especially in younger PLHA. Methodology This cross-sectional study aimed to estimate the prevalence of frailty in PLHA (18 - 50 years) who had been on ART for 24-60 months and identify markers linked to frailty. Frailty was assessed in 152 subjects using the Fried frailty-index. Parameters measured included the mid-upper arm and calf circumferences, pain-severity (using the Brief Pain Inventory), highly-sensitivity C-reactive protein, d-dimer, and interleukin-6. Results The prevalence of frailty and pre-frailty were 6.58% and 23.02%, respectively. Reduced grip strength and self-reported exhaustion were associated with frailty (15.79% and 13.16%, respectively). Low calf-circumference and mid-upper arm circumference were not significantly associated with frailty/pre-frailty. The prevalence of pain was 21.7% and both pain severity and pain interference were significantly associated with frailty/pre-frailty. CD-4 counts at the time of assessment showed an inverse association with frailty. Elevated C-reactive protein (CRP of 0.04 associated with 0.49 probability of frailty (95% CI 0.40 – 0.59), CRP of 0.12 associated with 0.63 probability of frailty (95% CI 0.47 – 0.76)). D-dimer levels were not significantly associated with frailty /pre-frailty. Conclusion In this first-of-its-kind study on frailty in young PLHA (mean age 37 years) from the Indian sub-continent, the prevalence of frailty and pre-frailty was 6.58% and 23.02%, respectively. Multivariate analysis showed a strong association of frailty with pain severity, CD4 count at time of assessment, hs-CRP levels and duration of ART.

The Application of Immunoglobulins Immune Response in the Discovery and Development of Safe Therapeutic Agents: A Review Article

Jan 2024 DOI 10.14302/issn.2328-0182.japst-23-4771
Tariku Belay YilkalCorresponding author

Background Immunoglobulins are bio-receptors found embedded in the cell membrane with a biological role that detects the harmful molecules of a test compound. These bio-receptors interface between a biological system and its external environment that transduce information to the effector via intermediate messengers in which its response efficiency usually exhausts at high doses of exposure to external stimuli. The purpose of this review article is, therefore, to elaborate on the computational method for systemic biology which was designed to convert qualitative pharmacological data into the quantitative one that might help to determine the toxicity of a test compound. Methods First, acute toxicity studies using different levels of doses prepared from each test compound have been conducted on Balb c mice. Then, blood specimens from the tail and facial veins of each sampled Balb c mouse were collected 3 days before dosing as a reference test and 4 hr after dosing for comparison. The changes in the efficiency of immunoglobulins immune response (ΔIg) after dosing were determined using quantitative immunoassay and the body’s response against the dose as the toxic reaction rate (r) and the toxic severity (s) were finally determined using computational methods as r=d/t-ΔIg mg/sec and (s=r/w×100) %/sec respectively, where (w) represents the body weight of a study animal, (t) represents the period of time at which undesirable bio-physiological responses manifested on treated study animals and (ΔIg) represents the changes in the concentration of immunoglobulins in blood serum after dosing. Results The results of different studies revealed that the dose has never limited the toxic property of a test compound but the length of time at which the undesirable side effect was manifested on study animals. The period of time at which adverse effects manifested on treated Balb c mice was inversely related to the amount of dose administered in the oral route. The higher the dose of the administered test compound, the shorter the period of time at which the undesirable side effect was manifested on treated Balb c mice. This means that the adverse effect of test compounds was not because of the dose but rather due to its toxic reaction rate which ultimately determined the toxic severity in the natural process of treated Balb c mice. Balb c mice treated with a dose whose toxic reaction rate was ≤ 0 survived from death whereas Balb c mice treated with a dose that had a toxic reaction rate of > 0 died at different lengths of time after dosing depending on the toxic severity of a test compound. It could be a scientific fact to declare that a test compound is safe when the toxic reaction rate (r) and toxic severity (s) of a dose is ≤ 0 and toxic when it is > 0 in the natural processes of a study animal.

The debate of care uses the role of different actors from the interpretation of the debates and discussion groups carried out during the fieldwork. We identify here: the elderly person, the caregivers - here in this article in their wide variety, from family members to hired workers, especially immigrant women- and thirdly, as the third aspect of the triangle, and which remains in this chapter more blurred, from municipal and health public services. This care triangle is also very affected by the adverse effects of the pandemic.The pandemic highlights the existing systemic equalities, particularly affecting migrant women and ethnic minorities, people who work in the care sector and health personnel.

A case of delayed allergy after cyanoacrylate closure of varicose veins, diagnosed by drug-induced lymphocyte stimulation test

Sep 2023
Suzuki HiroyukiCorresponding author

Objectives The number of cases of cyanoacrylate closure (CAC) system for varicose veins has been increasing worldwide. However, as this is a new treatment method, the potential adverse effects and other details remain unclear. In particular, the cause of inflammation in embolized veins is still under debate. Methods We performed a drug-induced lymphocyte stimulation test (DLST) on a patient with allergic-like symptoms after CAC.  Results The DLST was strongly positive in this case, and the patient underwent total removal of the CAC-filled vein due to difficulty controlling the symptoms with medication. After that the state was recovered and no medication was continued. Conclusion We encountered a case that a delayed allergy by CA after CAC treatment developed in, eventually leading to the total removal of the CA-filled vein. It was suggested that with doubting allergic-like symptom after CAC, DLST for CA could show not only the diagnosis of the delayed allergy to CA, but also the later treatment policy with stimulation index (S.I.) in the positive cases.

Auricular Vagus Nerve Stimulation Improves Chronic Pain and Pain-Related Cytokine Levels: A Clinical Study

Aug 2023 DOI 10.14302/issn.2688-5328.ijp-23-4624
James AndersonCorresponding author

Periauricular Vagus Nerve Stimulation (pVNS) has been proven safe and effective in reducing chronic pain and related comorbidities in numerous clinical studies. This multicenter, interventional study used a non-randomized, interrupted time-series analysis to test the efficacy of an 8-week treatment protocol using the Stivax neurostimulator device. Subjects (n=33, 15 F, 18 M, age 40-77) were recruited at 3 clinic sites in California and Colorado. All subjects had long-term chronic pain and had failed other treatments. Subjects were treated with the Stivax device 3 times (2 weeks on, 1 week off). Subjective assessments of pain (Visual Analog Scale), disability (Oswestry Disability Index), depression (PHQ-9), and activity (IPAQ-E) were collected at baseline and weekly. Objective blood levels of pain-related cytokines collected at the end of weeks 2 and 8. Most subjects reported reduced pain, disability, and depression, with increased activity levels. At the end of week 8, subjects reported an average reduction in pain by 38.5% (3 subjects reported no pain), depression by 43.6% (2 subjects reported no depression), disability by 38.6% (2 subjects reported no disability), and an average 26.1% increase in activity level (5 subjects doubled their activity level). Levels of the pain-related cytokines IL-1ꞵ, IL-2, IL-3, IL-7, IL-10, IL-15, IL-17α, IL-21, TNF-α, IFN-γ, and FLT3-ligand showed improvement at week 8. pVNS is believed to “reset” central sensitization underlying chronic pain and other central sensitization syndromes, engaging the body’s pain modulation systems. Our results indicate that pVNS can clinically significantly improve chronic pain and associated morbidities without adverse effects.

Introduction Malaria in pregnancy is a serious public health concern that could result in detrimental health outcomes for pregnant women and their foetuses. In Nigeria, there is still a significant risk of the disease epidemic and adverse effects especially in pregnancy. The aim of this study is to assess the socio-demographic factors associated with Intermittent Preventive Treatment and health seeking behaviours for malaria in pregnancy among women of reproductive ages in Nigeria Methods Using the National Demographic Survey (NDHS) 2018 data, a cross sectional study was conducted to assess socio-demographic factors associated with Intermittent Preventive Treatment (IPT) for Malaria among Nigerian women of reproductive ages. Result Majority were between ages 30-39 years (39.5%), married/cohabiting (91.8%), Muslims (59.5%), from the north (68.9%), uneducated ( 49.9%), poor (47.5%), and grand parous (65.7%). 63.4% of the women had taken fansidar for malaria in pregnancy while only 6.1% had received healthcare for malaria from informal sources. Except for marital status, all socio-demographic variables (regions, highest educational level, wealth index, age group, religion and parity) were significantly associated with intake of IPT. Additionally, region, education, wealth index, age group, marital status and religion were associated with health seeking behaviour for malaria in pregnancy (P<.05). After control for other variables, wealth index, highest educational level, married/cohabiting marital status and religion was significantly associated with intake of IPT while region, primary and secondary education, poorer and richest wealth index, widowed/separation influenced health seeking for malaria in pregnancy (P<.05). Conclusion The National Malaria Elimination programme should evaluate existing policies that develop interventions that are centred on high risk population in order to prevent malaria in pregnancy while improving health seeking behaviours of women of reproductive ages.

Many marine and freshwater fisheries are now in a very poor state, and many fish stocks are close to collapse. There is a need to manage fisheries more carefully, especially since fishing can affect other aspects of the environment. It is also important to reduce the adverse effects of climate changes upon the marine and freshwater environments, fishes, and other animals, and the need to manage other human activities taking place in the sea, to improve the marine environment and protect the wildlife and the fishing activities. Marine pollution, includes human waste materials, chemicals and plastics, and there is also noise and substrate vibration, from industrial and other activities that may affect both the abundance and quality of fishes and other marine animals. This paper deals with fisheries management, and environmental protection, and concludes that fishermen, fisheries scientists, fisheries managers and environmental interests must work closely together, if fishes are to be adequately protected, and fisheries are to be better managed. It describes current systems of management. It especially draws attention to the importance of moving towards an ecosystem-based approach to fisheries management. Such an approach aims to manage all those human activities that have an impact upon the marine environment and its life forms.

Dolutegravir: Pharmacokinetics and Pregnancy Profile

Mar 2022
Bereda GudisaCorresponding author Department of Pharmacy, Negelle Health Science College, Guji, Ethiopia

Dolutegravir suppresses this integration enzyme, so human immune virus can’t create every greater copies of itself, thus ‘’integrase inhibitor.’’ Dolutegravir is hastily absorbed pursuing oral administration. The median maximum plasma concentration is reached 1.5–2.5 hours after oral uptake with a mean half-life of 12–15 hours, rendering feasible for once-daily dosing without the need for pharmacological boosting. The terminal half-life is about 14 hours. The apparent oral clearance is about 1 liter/hour. Fifty three percent of the total oral dose of dolutegravir is excreted unchanged in the feces, thirty two percent through urine as glucuronide (eighteen percent) or alkylated product (three point five percent), and other organic conjugated products sequencing from phase II liver metabolisms. Dolutegravir’s categorized as pregnancy category B (no confirmation of pitfall in humans) means either animal-reproduction inquests have not substantiated a fetal peril but there are no restrained inquests in pregnant women or animal-reproduction inquests have reveal an adverse effect (distinctive than a de-escalate in fertility) that was not inveterate in restrained inquests in women in the first trimester (and there is no confirmation of a pitfall in later trimesters) or there is survey in animal that revealed the medication is safe in pregnant animal, but there is no fetal pitfall confirmation in pregnant women.Antiviral Pregnancy Registry (APR) revealed that as of January 2017, pregnancy outcomes and birth defects were analyzed from 142 pregnancies with reported exposure to DTG during pregnancy. There were 128 live births reported (3 terminations, 11 miscarriages, no stillbirths). Only 4 (3.0%) reported birth defects, which is similar to the expected rate of birth defects in the general population. European Pregnancy and Paediatric HIV Cohort Collaboration (EPPIC) displayed that as of July 2017, 101 pregnancies with exposure to DTG had been identified with 84 birth outcomes. Rates of preterm delivery and “small for gestational age” were identical to outcomes reported from women on alternative regimens (standard of care in the United Kingdom of Great Britain and Northern Ireland).

The stocks of the Atlantic salmon (Salmo salar) in many rivers in North America and Europe have declined in recent years and are experiencing a crisis. Despite their high degree of legal protection, the quality of their aquatic environments within rivers and in the sea, including local coastal waters, appears to be deteriorating. Salmon survival, has declined both within the sea and within rivers. The status of the Atlantic salmon stocks is considered here, together with the adverse effects of different sources, and those steps that may need to be taken to improve the condition of the salmon. This paper is intended to assist management bodies in taking steps to resolve the problems that exist for salmon, both within rivers and in the sea. It makes particular use of information available on the River Dee in Scotland.

The hippocampus is involved in learning and memory processes, an integral component of cognitive function. The aim of this study is to assess the efficacy of quercetin on manganese-induced neurotoxicity in the hippocampus of the adult mice. In this study, 40 adult mice of average weight of 18 –29g were randomly distributed into five groups of eight each. The brain was harvested and the region of the hippocampus was grossed for histological and immunohistochemical analysis. The results revealed a significant increased level of oxidative stress markers of manganese treated mice when compared with the normal control and quercetin treated animals (p<0.05). Immunohistochemical analysis also showed a decrease expression of Tumour necrosis factor alpha (TNFα) with quercetin treated animals when compared with manganese treated animals indicating its neuroprotective function. In addition, quercetin treated animals all had an improved working spatial memory in Y-maze test. The histological results also revealed a degeneration of pyramidal cells with a characteristic pyknotic activities at the granular layer of the hippocampus leading to neuronal integrity damage following chronic exposure to manganese but normal architectural design was however maintained with quercetin. Conclusively, exposure to manganese in excess may have adverse effect on extensive neuronal degeneration that could affect the learning, memory and possibly spatial navigation ability of miceand quercetin attenuates this induced neurotoxicity via inhibition of oxidative stress and reduction of TNF expression.

The telomeres existing at the end of the eukaryotic chromosome, play an important role in localization, pairing of homologous chromosomes during cell division and synapsis formation, while telomerase is involved in maintenance of the telomere length. The application of antiHIV-1 molecules particularly NRTIs have been shown to interfere with telomerase function thereby inducing aging processes. Since the application of these molecules has already indicated production of oxidative stress and toxicity in AIDS patients, their adverse impact on telomerase function may further worsen the situation. In addition, the negative influence of antiHIV-1 regimens on certain host factors involved in telomerase function may enhance aging. HAART changes the landscape of the disease by progressively decreasing the progression of HIV-1, but exerts prolonged adverse effects on the telomerase function. Though there is no exact information available on this issue, intensive efforts are needed to explore regulation of telomerase expression in HIV infected individuals and particularly those receiving antiretrovirals. 

Triacontanol Alleviated Nickel Toxicity in Maize Seedling by Controlling Its Uptake and Enhancing Antioxidant System

Triacontanol (TRIA) role in improving growth, physiological activities and tolerance against abiotic stresses has been reported. Yet, the mechanism by which TRIA executes its effects remains elusive. This work therefore studied the possible role of TRIA exogenous application in counteracting the adverse effects of nickel (Ni) treated maize seedlings. Maize seedlings (15-day-old) were grown in washed sand irrigated with nutrient solution provided with 100 μM NiCl2. Two concentrations of TRIA (25 and 50 µM) were applied twice as a foliar spray for Ni-stressed seedlings. Shoot and root growth attributes, Ni content, and antioxidant defence systems of maize seedlings were determined. Ni treatment reduced the shoot and root length and biomass, causing necrosis of the old leaves,greater reduction was shown in the roots. The shoot and root length was negatively correlated with their Ni content, which was consistent with their content of H2O2, but not with their malondialdehyde (MDA) content. As the roots had the greatest Ni content, maximum peroxidase (PX) and glutathione reductase (GR) activity as well as the highest ascorbic acid (ASA) and reduced glutathione (GSH) content were observed in the roots. The Ni-induced deleterious effects were alleviated by foliar application of TRIA concentrations. Also, TRIA treatment minimized root Ni content, whereas it maintained the shoots unharmed by Ni. Such mitigative effects of TRIA are explained by its key role in enhancing antioxidant capacity (expressed as IC50), increased PX and ascorbate oxidase (AO) activity, GSH, and total phenolic contents.

Obesity can be defined as a condition of abnormal or excess fat accumulation in adipose tissue, to the extent that health may be impaired. Fennel is one of the oldest spice plants which widely grows in arid and semi-arid and due to its economic importance and pharmaceutical industry usage. This plant has anti-inflammatory and analgesic effect and is effective in gastrointestinal disorder treatment. The aim of the present study was to evaluate the phytochemical characteristics and therapeutic properties of this medicinal plant. The current study demonstrates that the alteration induced by high fat diet causing changes in blood parameters. These changes are exhibited through a decrease in RBCs, Ht, Hb and platelet and these changes could be due to oxidative stress, which lead to lipid peroxidation in RBCs membranes, auto oxidation of hemoglobin. As regards the total WBCs, lymphocytes and monocytes showed marked decrease. While a distinct increase in the percentage of neutrophils and eosinophil. The present, demonstrates that rats treated with (fennel), (ator) and (fennel with ator) exposure provided significant protection to the altered hematological variables. The effect of the treatment with fennel and ator more effect than fennel only and ator only. The finding of this study indicates that the concentration of Malondialdehyde (MDA) and Myeloperoxidase (MPO) in liver homogenates of the fennel and ator group significant decrease than group (3) and group (4) and the obese group. There is a growing awareness that obesity is a prime risk factor for the development of dyslipidemia profile and that oxidative stress may play a role in various adverse effects of obesity.

Retracted: Impact of Chlorpyrifos on Mosquito Larvae as Bioindicator in El-Beheira Governorate, Egypt.

Oct 2019
Radwan EHCorresponding author Department of Zoology, Faculty of Science, Damanhour University, Egypt.

Pesticides are the major source of concern as water pollutants. Persistent organochlorines can accumulate in food chains. Chlorpyrifos (O,O -diethyl O -(3,5,6-trichloro-2-pyridinyl) phosphorothioate; CAS No. 2921-88-2; CPY). CPY is a widely used organophosphorus insecticide that is available in a granular formulation for treatment in soil. Pesticides are used to control a wide range of pests including Mosquitoes. Mosquito borne diseases infect millions of people every year globally. The aim of current study was to screen the fresh water pollutants, water quality parameter in irrigation water from El Mahmodia stream, El-Beheira Governorate, Egypt and to determine the adverse effects of Chlorpyrifos on the larvae of Culex mosquito larvae as bio-indicator. The LC95 of Chloropyrifos insecticide was 6331.30 at 24h and increased to 230506.4 after 48h of exposure to the Chloropyrifos insecticide. It is noted that the effect of the exposure time of Chloropyrifos insecticide on the LC50, LC25 and LC95 values had a synergistic interaction with time, as it increased after 48h of exposure when compared to 24 h of exposure. The 0.09 ppm concentration of Chloropyrifos had no effect on the second instar Culex larvae, as there is no mortality over time; the same result is also with the control 0 ppm. There is no effect after 72, 96h of exposure of the population to the detected insecticide. This study concerns with studying the pollutants along El Mahmodia stream in El Beheira governorate in Abo Homs city with its abundance during the four seasons (2016-2017), as well as studding the physicochemical parameters in it. Another concern of this study is estimating the effect of one of this pesticides (Chloropyrifos) insecticide on the second instar Culex mosquito larvae, determining the lethal concentration of this insecticide on the Culex larvae. Along the study area, pesticides are used within a high ratio on the agriculture scale with its four main categories organophosphates, organochlorine, pyrthoid and carbamates. Organophosphates and organochlorine are used at a wide range. Pollutants measuring achieved by using GC-MS as water samples collected seasonally and analyzed, there is a big number of Pollutants which was found as well as other compounds which are banned, such as DDT. The physicochemical parameters Turbidity, COD, BOD in El Mahmodia stream exceeded the desirable limits of (Egyptian Law 48/1982), (WHO, 1993) and (FAO, 1985) although the other parameters as EC, PH, DO,TDS TSS are to be within the permeable limits. HCO3, NH4. Cu also was found to exceed the desirable limits while, Pb, Mn, Fe and Cd within the permeable limits. Chloropyrfos as an organophosphate pesticide used in the present study which was found with 0.09 mg/l in the stream water, used to estimate its effect on the Culex mortality, determining LC25, LC50 and LC95. The experiment continued for 96 h but after 48 h there is no effect of Chloropyrfos on Culex larvae. The experiment began with 20 second instar Culex larvae immersed in 100 ppm, 10 ppm, 1 ppm, 0.1 ppm and finally 0.09 ppm of Chloropyrfos insecticide with five repeats to each concentration, it is noted that the lethal concentration increase after 48h of experiment, the larval mortality decrease with time.

The problem associated inappropriate management of municipal waste to the ecosystem cannot be overemphasized. This study involved the physical characterization of municipal solid waste streams in 4 commercial dumpsites in Yenagoa Metropolis, using the quartile estimate method. Results showed that out of a total mass of 79.82kg; the individual mass composition was reported for garbage (food) waste 33.32 (39%), paper waste 14.90 kg (40.82%), plastic waste 5.12 kg (6%), nylon 11.01kg (13%), metal 4.31 kg (5%), wood 2.29 kg (3%), electronic 5.69 kg (7%), glass/ceramic 3.48 kg (4%) and unclassified waste whose mass was 4.62kg (5%). Disposal of untreated and unsegregated/uncharacterized waste adverse effect to the environment. It is hereby recommended that the populace to desist from illicit disposal of waste stream. In addition all stakeholders and Government in particular should formulate policies the reduction, reuse and recycling of waste stream.

The ecotoxicological effects of leachates from dumpsite have become a major problem. Leachates arising from waste dumpsites are transported by surface runoff or infiltration through the soil and become bioavailable in the ecosystem. The ecotoxicological assessment of leachates from 6 dumpsite in Yenagoa Metropolis were investigated against adult and fingerlings of Clarias gariepinus (African catfish). Ecotoxicological activities (LC50 values) were reported for the following stations; Akenpai (124.57 ppm), and Etegwe stations (95.38 ppm), as well as Opolo (157.95 ppm), and Kpansia Markets (123.82 ppm). In addition, leachates of the two stations from the central dumpsite (CDS), were the most active (CDS 1; 60.97 ppm, and CDS 2; 76.65 ppm). Notwithstanding, the order of toxicological activities of the leachates were reported as; CDS 1>CDS2>Etegwe>Akenpai>Kpansia market>Opolo Market. These results confirm the toxicity of leachates from the dumpsites. In addition, we recommend that government, regulators and all stakeholders should enact policies to treat, reduce, recycle and reduce waste stream in order to mitigate the adverse effects on the ecosystem.

Introduction: The introduction of preexposure prophylaxis (PrEP) against incident HIV infection has changed the epidemiology of disease as continuous treatment with tenofovir and emtricitabine among high risk groups can reduce the relative risk for incident HIV infection by over 90%.However,despite the approved use of TDF+FTC, as a fixed dose combination of emtricitabine 200 mg and tenofovir disoproxil fumarate 300 mg, for oral PrEP since 2012 , it does not appear to have become widely accepted and in use among healthcare workers especially those in low income countries. Researches are therefore needed to consider the awareness and practice of health workers towards the availability of PrEP services in this part of the world. Healthcare workers are expected to be promoters of the use of PrEP services. Method: A cross sectional questionnaire-based study conducted in southern Nigerian over a 6 months period. Data were collected from 250 healthcare workers using interviewer-administered questionnaires. The data analysis was done using statistical package for the social sciences (SPSS) for windows version 20.0 software (SPSS Inc; Chicago, IL, USA). Frequency counts were generated for all variables and statistical test of significance was performed with chi-square test. Significance was fixed at P < 0.05 and highly significance if P < 0.01. Results: A high proportion of the respondents(>60%) were highly educated healthcare workers(majorly Nurses and medical doctors) and about half (55%) having at least 10yrs working experience in the health sector with most especially on the HIV program(>90%), majority (94%) of the health workers were aware about ARV pre-exposure prophylaxis but very few ( 6% )could give the standard definition for PrEP as the use of ARV drugs by HIV negative persons to prevent the acquisition of HIV.Most(67%) of them gave wrong definition for PrEP and worse still about one fifth (20%) had no idea what PrEP was all about. Most (70%) could not correctly identify all the ARV drugs in a standard PrEP regimen while about 35% had no idea at all of the approved ARVs used for PrEP. Though PrEP services was not available at any of the facilities where the respondents were working ,the approved drugs(TDF+FTC) for PrEP were available at about 40% of the health facilities(public and private) and 15% community pharmacies in the vicinity of the respondents . Only 60% of the respondents were willing to access PrEP service for themselves if indicated while 35% would not use such services even if it is indicated for reasons which include concern about adverse effects and safety.Awareness of PrEP was significantly associated with the ability of the healthcare workers to identify the correct ARV regimen, ARV dosages and also correct indication for PrEP. Awareness was also associated with the knowledge of the correct proven efficacy for PrEP(>95%) and high likelihood of seeing a patient placed on PrEP and willingness to use PrEP based on personal indication Conclusion: The level of awareness of PrEP among healthcare workers was very high at about 90% yet many(60%) could not give correct standard definitions of PrEP, PrEP ARV regimen, dosages and level of efficacy of PrEP. Also none of the respondent had PrEP services available either at their center or any known referral centers. This is unacceptable in a country with second highest HIV burden in the world and has adopted PrEP in her national HIV guideline with ongoing PrEP demonstration studies. The few healthcare workers who were able to mentioned this information were more likely to have seen a patient placed on PrEP and were more willing to use PrEP based on personal indication. Recommendations: There is need to deepen the and knowledge of PrEP among healthcare workers especially those in poor resource settings by engaging them through update courses outreach, educational resources, campaigns/seminars and workshops and various job aids. All healthcare service providers should be very comfortable to carry out HIV risk assessment of their clients and provide PrEP to those indicated directly or indirectly through referral

Microbiological and Nutritional Properties of Frankfurter-Type Fish Sausage

Fish meat is a common and broadly used food due to its high nutritional values yet the bones and flavour of fresh fish can be unpleasant. The unpleasant fishy flavour makes it difficult to handle and process. The fishy flavour is as a result of microbial presence and growth. Studies associated with microbial contaminations have concentrated more on the carcass. Such contaminations which affect the microbiological status of processed products can emanate from spices and other non-meat ingredients, environment, equipment and handlers. The successful application of processing/preservation technology results in the conservation of desirable qualities in stabilized and varietal fish products. This study sought to use fish in the manufacture of frankfurter-type sausages, which could have improved preservation characteristics without any adverse effects on sensory properties. The nutritional composition and microbiological safety of fresh fish and sausages were determined using the methods described by AOAC and ICMSF respectively. The study showed that, catfish sausages were higher in protein (15.69 %) and were lower in fat (10.66%) compared to the other sausages. Total Viable Counts (TVC) were within the accepted limits (106 and 107cfu/g) for fish and pork respectively. E. coli  was not detected in any of the treatments during frozen storage for 6 weeks. It was concluded that catfish frankfurter has high nutritive value because it contained less fat but with higher crude protein. Like pork frankfurters, both catfish and mackerel sausages could be stored for six weeks without any negative effects on microbial quality.

The concern over exposure to drinking water contaminated and the resultant adverse effect on human health has prompted several studies evaluating the quality of drinking water sources. This study was carried out to determine the bacteriological and Physico-chemical qualities of commercial borehole water within Otuoke community in Bayelsa state Nigeria. Ten (10) water samples were collected from the various locations designated as (A-J). The Physico-chemical parameters were determined by using the photometric technique through the Colour Q photometer and the bacteriological analysis was determined by using aerobic plate method. The Physico-chemical parameters of the water samples analysed were within the acceptable limit of WHO standard of drinking water quality except for Bromine and cyanuric acid which ranged from 1.6±0.1 to 2.7±0.1 and 2±1 to 9±1 respectively. The Result of total bacteria count obtained from the borehole water samples ranged from 1.1 x 105cfu/ml to 6.9 x 105cfu/ml and there was no detected growth for the faecal coliform count of most of the samples except for BHW-I and BHW-J which had 1.3 x 104 to 7.9 x 104 respectively. Bacteria isolated and identified using conventional biochemical test include E. coli (17.9%), Klebsiella spp. (35.7%), Salmonella spp(25.0%), Enterobacter aerogenes (21.4%) The study therefore suggests that all the borehole water tested in Otuoke and environs are considered unsafe for consumption and therefore regular treatment before usage is recommended.

Hinzpeter JaimeCorresponding author Medical Doctor, University of Chile, Clinical Hospital, Santiago Chile

Objective: The purpose of this study is to evaluate the use of paralytic shellfish poisoning toxin in a patient with arthrofibrosis of the knee. Arthrofibrosis is a common complication of knee surgery that tends to manifest itself as a limitation of the musculoskeletal ranges. Paralytic shellfish poisoning toxin has been proposed as an alternative treatment for painful musculoskeletal pathologies. Subjects: Use of paralytic shellfish poisoning toxin in arthroscopic menisectomy. Case report. Methods: Three doses of paralytic shellfish poisoning toxin were administered in an intra-articular manner on different days. Functionality, musculoskeletal ranges, pain at rest and pain during motion were evaluated. Results: The current alternatives for management of arthrofibrosis include the use of oral steroids, physiotherapy, mobilization under anesthesia and the liberation of arthroscopic debris. This case is the first report of the use of paralytic shellfish poisoning toxin. The adverse effects the patient presented coincided with those described in the literature but without the presence of severe reactions. Improvement in functional tests, progress in musculoskeletal ranges and a decrease in the level of pain were achieved. Adverse effects included parenthesia and a feeling of weightlessness.

The research work on malarial infection and malarial treatment has been increased tremendously over the years due to increased resistance of parasites to antimalarial drugs. To overcome the developed resistance, antimalarial drugs are used in combination. But eventually the amount of drugs administered increase with the resistance and extend to adverse effects. Many innovative, sophisticated delivery systems have been developed to increase the adequacy, competency and efficiency of antimalarial drugs. But it is predicted that these new inventions will also acquire resistance with time. Globally, it is seen that the countries which have low standards of hygiene have high levels of malarial infection. There are various antimalarial techniques developed and are slowly being adopted worldwide. But the first step is to maintain the hygiene and cleanliness so that mosquitoes will not harvest.

Minimal Risk Level Derivation for Cadmium: Acute and Intermediate Duration Exposures

Faroon ObaidCorresponding author Division of Toxicology and Human Health Sciences, Agency for Toxic Substances and Disease Registry, Atlanta, Georgia

The Agency for Toxic Substances and Disease Registry (ATSDR) lists cadmium as one of its priority hazardous substances. The agency conducted a comprehensive literature review of cadmium and used the information to develop a toxicological profile that identified the full range of health effects associated with exposure to cadmium. It included an assessment that identified screening levels, termed health guidance values or minimal risk levels (MRLs), below which adverse health effects are not expected. In this paper, we describe how MRLs for cadmium are derived. For the acute inhalation MRL, the traditional no observed adverse effect level or lowest observed adverse effect level (NOAEL/LOAEL) approach is used; for the oral intermediate MRL, the benchmark dose (BMD) approach is used. MRLs were developed for the most sensitive route-specific end points, other than mortality and cancer that were sufficiently supported and justified by the data. These included an acute duration (1–14 day exposure) inhalation MRL of 0.03 µg Cd/m3 for alveolar histiocytic infiltration and focal inflammation in alveolar septa and an intermediate duration (15–365 day exposure) oral MRL of 0.5 µg Cd/kg/day for decreased bone mineral density

Topical corticosteroids are main therapeutic agents for the treatment of a wide variety of dermatological disorders. Three cases of chronic cutaneous ulceration affecting the skin of the breasts that were caused presumably by previous and continued use of potent topical corticosteroids for the treatment of psoriasis and/or intertrigo lesions were reported here. These three cases were presented to emphasize the potential serious local side effects of topical steroids even progressing to ulceration in breast' skin. These cases highlight the importance of appropriate use of topical corticosteroids, necessity of a strict follow up for adverse effects and the need of warning every patient about possible side effects of topical corticosteroids

Objectives: The rate of morbid obesity among women of reproductive age continues to rise worldwide. Surgical treatment remains the most effective mean to face it. Anatomical, physiological and nutritional modifications lead to several challenges for pregnancy after bariatric procedures. In spite of routine supplementation after bariatric surgery, vitamin and mineral deficiency frequently appear in bariatric pregnancies. The aim of this review is to summarize the existing data on the prevalence and management of nutritional deficiencies in pregnancy after bariatric surgery. Methodology: A comprehensive search of Pubmed Database was conducted for English-language studies using a list of key words. Results: The most common post-operative deficiencies in pregnancy include iron, vitamin B12, folate, vitamin D and magnesium deficiency. Less common are selenium, vitamin A, vitamin B6 and vitamin C deficiency. Finally, copper, vitamin K, vitamin B1, vitamin E and albumin deficiencies are considered to be relatively rare. Conclusions: Pregnancy after bariatric surgery has been proven to be safe for both the mother and the fetus. However, there is still the risk of significant nutritional deficiencies with adverse effects on pregnancy and lactation. As a result, a thorough customized nutritional assessment is mandatory for every woman in reproductive age who has undergone a bariatric operation, with strict regular follow-up during pregnancy and lactation.

Reversal of Obesity: The Quest for the Optimum Dietary Regimen

A new approach to weight loss and weight loss maintenance is urgently needed, with the global epidemic of obesity leading to ever higher levels of chronic disease. This new approach should be cheap and simple, it should maintain essential nutrients and not deplete lean mass, should have minimal adverse effects and be carried out safely at home without support from the healthcare profession. This review looked at the forms of caloric restriction (CR) investigated in randomised controlled trials (RCTs) and found that supervised continuous and intermittent CR was more effective than other forms of weight loss over periods from 12 weeks to 2 years and could improve cardiovascular and diabetes risk factors. CR was equally as effective as bariatric surgery, suggesting that it is the post-surgery caloric restriction that has the impact on weight, rather than the surgery itself. Intermittent CR, including alternate day fasting (ADF), was as effective as continuous CR but may show improved compliance and higher lean mass. Unsupervised weight loss maintenance presents a greater problem, since in most weight loss regimens all the weight lost is ultimately regained. Although both continuous and intermittent CR can be effective, it has been found that ADF and a higher protein intake is more likely to maintain the weight loss. These results hold for all age groups and ethnicities and both genders. These findings suggest that intermittent CR, and particularly ADF, may be a viable form of weight loss and maintenance which fulfils all the criteria above. It is therefore recommended that larger RCTs investigate intermittent CR and ADF as a viable and cost effective form of weight loss and weight loss maintenance.

Aumeistere LivaCorresponding author Institute of Food Safety, Animal Health and Environment BIOR, Riga, Latvia

Background: Breast milk is the ideal food source that contains all components an infant needs. Infants are at risk of receiving possible pollutants and high levels of trans fatty acids through breast milk that may affect their cardiovascular health and cognitive development. Statistics indicate that the proportion of children who are breastfed up to one year of age shows an annual increase in Latvia. Objectives: 1. To review studies conducted among the Latvian population regarding breast milk composition. 2.  To evaluate the necessary future studies emphasizing the importance of the trans fatty acid content in a mother’s diet and correspondingly in breast milk and taking into consideration the new changes in Latvian legislation setting the maximum trans fat content in foodstuffs. Conclusions: There is very little research done about the human milk composition in Latvia that could be referable to a general population. It is known that the exposure of breast milk to persistent organic pollutants in Latvia corresponds to the lowest levels detected in the European countries and is not a cause of health disorders. Taking into consideration the adverse effect trans fatty acids have on human’s health regardless of the age, consumption should be as low as possible. Latvia has become the latest European Union country to set the maximum amount of trans fats in foodstuffs, yet there is no information about trans fatty acids content in human milk among women in Latvia. This problem needs to be addressed and set in motion. Therefore, it would be a novel idea to study if the TFA content also declines in milk among Latvian women after the introduction of the new legislation.

Trichomegaly is a known adverse effect with the epidermal growth factor receptor inhibitor (EGFRI) and prostaglandin analogue drug classes. We present a chronic Latanoprost user who developed symptomatic trichomegaly subsequent to initiating an EGFRI medication and believe this case offers evidence that the two classes of medications may cause a similar eyelash manifestation through different mechanisms.

Iodinated radiographic contrast agents (IRCA) are pharmaceutical agents used to improve the visibility of internal organs and structures in X-ray based imaging techniques. However, IRCA may have adverse unwanted effects, ranging from a mild inconvenience, such as itching, to a life-threatening emergency. The adverse effects of IRCA include delayed allergic reactions, anaphylactic reactions, and/or cutaneous reactions. But exposure to IRCA may be associated also with the development of either hyperthyroidism or hypothyroidism, presumably due to the effect of free, biologically active elemental iodine ions present in these agents. Among the side effects associated with the use of intravascular injection of IRCA, Contrast-induced nephropathy (CIN) is undoubtedly their most important and frequent well known adverse reaction. The pathogenesis of CIN is discussed in detail including the factors that increase the incidence of CIN, the main ones being pre-existing renal impairment, particularly when associated with diabetes mellitus. Finally, the measures to reduce the nephrotoxicity of IRCA are suggested beginning with monitoring renal function, discontinuation of potentially nephrotoxic drugs, use of either iodixanol or iopamidol at the lowest dosage possible. The main procedure for prevention of CIN is an adequate hydration of the patient with either isotonic sodium chloride or sodium bicarbonate solutions. A long list of references is provided that will enable readers a deep appreciation of the topic.

Quantitative Proteomics Using 15N SILAC Mouse

In biomedical research the use of mammalian tissues is crucial to increase our understanding of complex human diseases. Mass spectrometry-based proteomic approach has become the most powerful tool of studying large-scale protein expression profiles in mammalian tissues. To perform global proteome analysis quantification of mammalian tissues, we generated 15N SILAC mice to obtain tissue-matched labeled peptide libraries for mass spectrometry-based quantitative proteomic analysis. We developed a new labeling protocol to circumvent adverse effects of introducing 15N labeled diet to mice, and showed that the new labeling scheme has no significant effect on the fertility and reproduction of C57/BL6 mice. Using labeled tissues from these mice, we compared the reproducibility of mass spectrometry-based quantification with or without 15N labeled internal standards among biological replicates of young and old brains. We found that labeled-based quantification is less susceptible to variations from instrument conditions and produces more consistent quantifications among biological replicates than label-free quantification. Lastly, we showed that over 60% of peptides from the human brain are quantifiable with internal standards from 15N labeled mouse brain and therefore present a promising alternative of quantifying human tissues that do not have existing cell lines available for SILAC labeling.

Pattern of Use of Highly Active Antiretroviral Therapy Regimens and Pattern of Occurrence of Adverse Drug Reactions in an Indian Human Immunodeficiency Virus Positive Patients

Rajesh RadhakrishnanCorresponding author Radhakrishnan Rajesh M.Pharm, Asst Professor (Senior Grade), Department of Pharmacy Practice, Manipal College of pharmaceutical Sciences, Manipal University, Manipal- 576 104, Karnataka, India.

Background: In India, Human immunodeficiency (HIV) infected patients with highly active antiretroviral therapy (HAART) are at higher risk of developing adverse drug reactions (ADRs). Objectives: The aim of this study was to characterize the pattern of use of HAART, occurrence, incidence, severity and causality of ADRs to HAART in Indian HIV positive patients. Methods: This was a prospective observational study conducted between August 2009 and May 2012. Enrolled HIV positive patients were intensively monitored for ADRs with fixed dose antiretroviral therapy as per National AIDS Control organization (NACO).World Health Organization (WHO) definition of ADR was adopted to detect ADRs to HAART and classified based on WHO adverse reaction terminologies. Naranjo’s scale was used for causality assessment of ADRs. Preventability was assessed using Thornton and Schuman criteria and severity was assessed using the modified Hart wig and Siegel scale. Pattern of ADRs was assessed with patient demographics, ADRs characteristics, and pattern of drug and reaction characteristics. P-value <0.05 was considered as statistically significant. Results: A total of 426 ADRs to HAART were evaluated from 1982 HIV positive patients during the study period. The overall incidence of ADRs to HAART was 21.4%. Significant difference was seen in the incidence of ADRs in the age group of 41-60 years (p <0.001), CD4+T-cell counts of 350-500 cells/µl (p <0.001), females (p <0.001). Three fatal ADRs of with cutaneous drug eruptions of Steven Johnson Syndrome (SJS) and Toxic Epidermal Necrolysis (TEN) was 1.1%. Anemia (31.7%) accounted for majority of the reports followed by vomiting (15.5%), skin rash (12.9%) and peripheral neuropathy (10.7%). The suspected drug was withdrawn for the management of the ADRs in majority (27.9%) of the reports. Higher incidence rate of ADRs was noted with lamivudine (3TC) + nevirapine (NVP) + stavudine (D4T) (22.9%). In, naranjo's causality assessment, majority of the ADR reports were rated as possible (69%). Symptomatic treatment for ADRs was given in 91.8% of the reports and 86.4% of the reports the patient recovered from the suspected adverse reaction at the time of evaluation. Conclusion: In India, occurrence of ADRs to HAART in HIV infected patients was found to be higher with zidovudine induced anemia (31.7%). The higher percentage of ADRs to HAART was seen with female patients, age 41-60 years; CD4+ T-cell counts 350-500 cells/µl. Physician must focus for monitoring all lab investigations for early detection and prevention of adverse effects associated with HAART.
