Peste Des Petits Ruminants: An Update

Peste des petits ruminants (PPR) is a notifiable and reportable disease recognised by the Office Internationale Epizooties (OIE) and penned for eradication by 2030. It is an endemic and devastating disease of small ruminants in some countries of Africa, Asia, and the Middle East. The disease militates against small ruminant production and increased flock numbers in the region. Information and literature on the current review was especially obtained and compiled from CABI abstract data base, PubMed, Scopus, Elibrary USA and other online publications. This review highlights the viral structure, epidemiology, predisposing factors, clinical signs, pathology, immunoprophylaxis, diagnostic techniques and therapeutics of the disease with a view to generating increased scientific research interests on PPR. It is hoped that more robust scientific research breakthroughs could emerge particularly in the area of immunoprophylaxis, rapid penside diagnosis, and alternative therapeutics such as the use of probiotics. This will in no small measure boost small ruminant production, alleviate poverty and increase food security in countries endemic with the disease.

Mathematical modelling approach of the study of Ebola virus disease transmission dynamics in a developing country

Background: Ebola Virus causes disease both in human and non-human primatesespecially in developing countries. In 2014 during its outbreak, it led to majority of deaths especially in some impoverished area of West Africa and its effect is still witnessed up till date. Materials and Methods:We studied the spread of Ebola virus and obtained a system of equations comprising of eighteen equations which completely described the transmission of Ebola Virus ina population where control measures were incorporated and a major source of contacting the disease which is the traditional washing of dead bodies was also incorporated. We investigated the local stability of the disease-free equilibrium using the Jacobian Matrix approach and the disease-endemic stability using the center manifold theorem. We also investigated the global stability of the equilibrium points using the LaSalle's Invariant principle.Results: The result showed that the disease-free and endemic equilibrium where both local and globally stable and that the system exhibits a forward bifurcation.Conclusions: Numerical simulations were carried out and our graphs show that vaccine and condom use is best for susceptible population, quarantine is best for exposed population, isolation is best for infectious population and proper burial of the diseased dead is the best to avoid further disease spread in the population and have quicker and better recovery.

Immediate and early engagement of same-day antiretroviral therapy initiation among newly diagnosed people living with HIV in urban Zambia: a retrospective cohort study

Introduction: as Zambia moves towards attaining human immunodeficiency virus (HIV) epidemic control, it is clear significant efforts are required to facilitate achievement of UNAIDS treatment targets by 2030. To accelerate progress towards global target of 95% of people living with HIV (PLHIV) knowing their status, country is promoting community-based HIV testing and same-day antiretroviral therapy (ART) initiation. However, there are uncertainties of how this strategy affects immediate and early engagement in program settings. To address this research gap, we analysed a programme data of PLHIV newly diagnosed and initiated on ART in community and health facility settings. Study objectives were to estimate the proportion of immediate engagement, to estimate early engagement among newly diagnosed PLHIV and, to examine factors independently associated with immediate and early engagement in care among newly diagnosed PLHIV offered same-day ART initiation. Methods: we included all newly diagnosed PLHIV aged 18 years or older and provided same-day ART initiation between October 2018 and January 2019 in Lusaka District. Immediate engagement was estimated as proportion of newly diagnosed PLHIV who visited the health facility at least once within 14 days after same-day ART initiation, whereas early engagement as proportion of newly diagnosed PLHIV active 6 months after same-day ART initiation. Pearson's chi-squared test was used to assess association of outcomes with key background characteristics. Results: of 12,777 newly diagnosed PLHIV who initiated same day ART 7,943 (62%) were tested and initiated in the community. Overall, 6,257 (49%) engaged within 14 days (median 15, IQR: 13-37). Older individuals (36-49 years) were more likely to be engaged at 14 days (aRR 1.29; 95%CI 1.06 - 1.18; p<0.001) and retained at 6 months (aRR1.27;95%CI 1.21-1.34P<0.001) whilst risk of attrition at 6 months was highest in younger ages (18-24 years) (aRR 0.79;95 %CI 0.76-0.82; p<0.001). Conclusion: to adequately address the HIV epidemic targeted engagement approaches are required particularly in the younger ages.

Age and body stature, handgrip, and strength endurance analyses of elite weightlifters: boosting 1RM bench press

Abstract Aim: This study aims to characterize the body stature and age, handgrip, and endurance strength of elite male weightlifters, and ascertain the anthropometric features that can boost IRM bench press. Methods: Forty-four elite male weightlifters of different weight categories participated in this study. All participants were members of the Ebonyi state team in Nigeria. We assessed their body weight, height, arm span, arm girth, chest girth, hip girth, thigh girth, handgrip strength, 1RM, time for repetitions (TR), and the number of repetitions (NR) of bench press, using National Strength and Conditioning Association's guidelines. Results: 1RM bench press depends on waist and thigh girths, while the speed of bench press was associated with height and arm span of elite weightlifters. 1RM, NR, and TR of bench press depend on age, body weight, and BMI. Consistently, NR of bench press increase with age; range 18, 22 years, and body weight increases with age; range 28, 32 years, while handgrip strength reduces with age; range 38 years and above (p < 0.05). Conclusion: The strength of association of age, and BMI with strength endurance and 1RM bench press was robust and similar, but inconsistent with handgrip strength. It also suggests that enhancing the musculoskeletal structures of the thigh and waist could boost 1RM bench press while handgrip strength could not but reduces as age advances beyond 38 years.

Clinico-pathological analysis of osteomyelitis in cancrum ois (Noma) patients seen in Noma children hospital, Northwest Nigeria

Background: Cancrum oris is a rapid and devastating infectious disease of the orofacial region, which can be life threatening in its fulminant stage. Infection of bone (osteomyelitis) is a possible sequelae of Noma (cancrum oris) and is more likely due to late presentation especially in our environment. A literature search revealed scanty research describing osteomyelitis in Noma patients. Objective: To analyze the clinico­pathology of osteomyelitis in Noma patients diagnosed and treated at Noma Children Hospital, Sokoto.Methods: The design was a 2-year retrospective study of records of Thirty­two patients who had sequestrectomy secondary to osteomyelitis in Noma (Cancrum oris). Age, gender, jaws affected and side of involvement were analyzed Results: The age ranged from 2­11 years with mean ±standard deviation 5.47 ± 2.68 years was recorded. Osteomyelitis in Noma patients was found among 17 (53.10%) males compared to 15 (46.90%) females. In 20 (62. 50%) of the cases, anterior maxillary involvement was observed and the remaining 12 (37. 50%) was found at the mandibular posterior region and it is more common on the left side. Result of histopathology showed both acute and chronic inflammatory cells. Necrosis and bone hyperactivity was observed in most of the slides. Conclusion: Osteomyelitis is a common complication of Noma and its treatment is of paramount importance for adequate management of Noma patients.

Causes of death and post-mortem testing for SARS-CoV-2 in a tertiary hospital during the COVID-19 pandemic in Ghana

Background: Causes of death during the coronavirus disease 2019 (COVID-19) pandemic ranhttp://crossmark.crossref.org/dialog/?doi=10.4102/ajlm.v11i1.1766=pdf&date_stamp=2022-11-23ge from direct consequences of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection to deaths unrelated to SARS-CoV-2. Another feature of the pandemic is the post-mortem testing for SARS-CoV-2. Understanding these aspects of COVID-19 are essential in planning and limiting the impact of SARS-CoV-2 virus on healthcare systems. Objective: This study investigated the underlying causes of death and the presence of SARS-CoV-2 in bodies received at the 37 Military Hospital, Accra, Ghana, during the COVID-19 pandemic. Methods: The study was conducted from 4­27 May 2020. Deceased patients that met the inclusion criteria were prospectively selected during the expanded surveillance period for SARS-CoV-2 testing, autopsy and determination of underlying and immediate cause of death. Results: A total of 161 deceased patients were analysed with 53 autopsies. The overall positive test rate for SARS-CoV-2 was 14.9% (24/161 patients), with a positive rate of 5.0% (8/161 patients) for nasopharyngeal samples and 30.2% (16/161 patients) for bronchopulmonary samples. The underlying causes of death were not related to SARS-CoV-2 infection in 85.1% (137/161) of patients, SARS-CoV-2-associated 12.4% (20/161) and SARS-CoV-2-induced in 2.5% (4/161). Cardiovascular complications formed the most common cause of death in patients with or without SARS-CoV-2. Conclusion: There was a high positive rate of SARS-CoV-2 in post-mortem cases. However, most deaths were not caused by SARS-CoV-2 but by cardiovascular complications. The high rate of bronchopulmonary positive results for SARS-CoV-2 requires that autopsies be done in suspicious cases with negative nasopharyngeal sampling.

Pregnancy Malaria: Predisposing Factors, Burden and Management in Agrarian Settlements Southeast Nigeria

Aim:To evaluate predisposing factors, burden and management of malaria amongst pregnant women in some agrariansettlements southeast Nigeria.Study Design:Cross-sectional survey conducted in 4 randomly selected agrarian communities was conducted Place and Duration of Study:Isi-Uzo Local Government Area (Eha-Amufu, Ikem, Mbu, Neke and Umualor). The study lasted six months.Methodology: A total of 385 respondents participated. A cross-sectional survey was conducted in 4 randomly selected agrarian communities was conducted. Data were collected using a structured questionnaire.Results: Obstetric and socio-demographic characteristics of the participants showed that majority were age-bracket 25-34 (42.6%), 1sttrimester (56.4%) and multigravidae (52.8%), primary education group (32.2%), secondary education group (55.6%), farmers (73.1%) and Christians (93.5%). All the respondents (100%) agreed to the presence of overgrown bushes in their environs, many farming activities which is the main source of income and staying out late at night for relaxation. A high percentage of the women experienced fever (57.9), headache (61.6), cough & catarrh (54.5) and anorexia (53.8) monthly reflecting high malaria frequency in the locale. 20.3% had experienced stillbirth, 82.6% neonatal death and 65.5% infant mortality once, twice or more. And according to (58.7%) and (38.7%) of respondents, malaria moderately and highly affects their productivity during pregnancy respectively. Respondents that seek health/treatment in hospitals (50.9) differ insignificantly from those that seek health through traditional remedies (49.1). Cost of treatment was reported to be high and moderate by 31.9% and 65.5% respondents respectively. Poor healthcare delivery was implicated as major dissatisfaction with treatment by 76.4% of respondents.Conclusion:Malaria is a major health problem encountered by pregnant women in agrarian locales. Hence, girls should be exposed to malaria awareness programs an earlier stage of life

Effect of Parental Socio-economic Status and Lifestyle Habits on Risk of Childhood Obesity in a Developing Nation: A Cross-Sectional Study

Background:The prevalence of childhood obesity (COB) in the developing world is currently high and is rising rapidly. Unlike developed countries, studies evaluating the association between parental socio-economic status (SES) and risk of COB in developing countriesare limited. Besides, the association varies across country and race/ethnicity and changes overtime. The aim of this study was to assess the association between parental SES and life style habits (LSHs) and risk of COB in Uyo, Southern Nigeria.Methods:Five hundred pupils and the corresponding number of parents were examined between April and September 2018 using socio-demographic/LSHs assessment questionnaire and body mass index (BMI) evaluation. Data analysis was performed and frequencies and percentages were computed. Associations between SES and LSHs of parents and risk of COW/COB were evaluated using multiple logistic regression analysis. Odds ratios and corresponding 95% confidence intervals were estimated.Results:The prevalence of COW and COB was3.4% and 16% respectively. The risk of COW/COB was higher among children whose parents had high level of education (OR=1.81, C.I=1.985-3.327,P=0.046), high level of income(OR=16.07, C.I=3.773-68.455,P=0.0001), employed(OR=1.138,C.I=0.157-12.057) and poor dietary habits. High level of physical activity of fathers and high income level of mothers decreased the risk of COW/COB Conclusion: High SES and poor LSHs of parents are associated with increased risk of COW/COB. Interventions necessary to reduce high prevalence of COW/COB in our cities and other developing countries should include among other risk factors parental SES and LSHs.

Rifampicin resistance patterns and dynamics of tuberculosis and drug-resistant tuberculosis in Enugu, South Eastern Nigeria

Introduction: Tuberculosis (TB) continues to be a public health problem globally. The burden is further exacerbated in developing countries like Nigeria, by poor diagnosis, management and treatment, as well as rapid emergence of drug-resistant TB. This study was conducted to evaluate the prevalence of drug-resistant TB, determine the rpoB gene mutation patterns of Mycobacterium tuberculosis (MTB) and model the dynamics of multidrug resistant TB (MDR-TB) in Enugu, Nigeria.Methodology: A total of 868 samples, from patients accessing DOTS services in designated centres within the zone, were screened by sputum-smear microscopy, while 207 samples were screened by Nucleic Acid Amplification (Xpert® MTB/Rif) Test (NAAT). A deterministic model was formulated to study the transmission dynamics of TB and MDR-TB, using live data generated through epidemiological study.Results: The results showed TB prevalence values of 22.1% and 21.3% by sputum-smear and NAAT assays, respectively. Analysis of the rifampicin resistance patterns showed the highest occurrence of mutations (50%) along codons 523 ­ 527. Factors such as combination therapy, multiple therapy and compliance to treatment had influence on both prevalence and development of TB drug resistance in the population.Conclusions: This first documentation of Rifampicin resistance patterns in MTB from Nigeria shows that a majority of rpoB gene mutations occurred along codons 523 to 527, contrary to the widely reported codon 531 mutation and that multiple interventions such as combination therapy, with good compliance to treatment are needed to reduce both prevalence and development of TB drug resistance in the population

Nephrotoxicological Effect of Water Soluble Fraction of Bonny Light Crude Oil in Wistar Albino Rats

This study evaluated the Nephrotoxic effect of water soluble fraction (WSF) of Bonny Light Crude Oil (BLCO). After preparation of the WSFand a range finding test, the Wistaralbino rats were administered three concentrations (25%, 50% and 100%) of WSF of BLCO for 30 and 60days. Data from the study showed that Urea concentration increased significantly (p≤0.05) with increasing dose of BLCO ranging from 14.71mg/dl in the control to 35.28mg/dl in the 100% group after 30days and 14.28mg/dl in the control to 41.08mg/dl in the 100% group after 60days, Creatinine concentration increased significantly (p≤0.05) from 0.22mg/dl in the control to 0.82mg/dl in the 100% group after 60 days administration while electrolyte (Na, K, Cl) concentration increased significantly (p≤0.05) with increasing dose of BLCO after 60days administration. Histopathological examination of the kidney was characterized by partial partitioning of the glomerular tufts, obliteration of the Bowman’s capsule and distortion of the renal tubules. The findings in this research suggest that WSF of BLCO induced nephrotoxicity.

Strategic Policies in Expanding Frontiers of Food Security among Cassava-based Farmers in Cross River State, Nigeria

The research was carried out to identify the possible constraints and development of strategic policies in expanding and improving cassava production and processing amongst cassava value chain actors in Cross River State, Nigeria. Data generated from the research the 150 cassava producers and processors (cassava value chain actors) through the use of well- define structured interview schedule was collated. The Multistage sampling procedure was adopted in selection of farmer respondents. The multivariate analytical technique was used in analyzing generated data employing the statistical application software of Genstat version 12. The eigen value, percentage variations and loading values contributing to low cassava output were used in achieving the objectives. The results showed that the major constraints to cassava production and processing were agronomic, technical/institutional and financial constraints. The major policy strategies should include a global, national, regional and community strategies all geared towards the evolution of industry analysis for improving cassava productivity in the study area through the development of the traditional farming systems, making good planting material accessible to farmers and on time and at lowest possible prices; the provision of credit facilities to the resource poor cassava –based farmers in the area with no collateral; the establishment of cassava product based cottage industries in the area for cassava value chain development; provision of adequate cassava processing equipment and the formation of cassava farmers’ multipurpose cooperative societies to enhance farmers’ access to benefit from world bank assisted programmes; have free access to basic information and production facilities. The study, therefore, recommended that cassava product based cottage industries be established in the study area in order to encourage both producers and processors in the value addition chain. This will also provide employment and likewise encourage the restive youths in the region to venture into agriculture as a business for economic returns, growth and development of the area. The identified constraints with the higher loading values for each of the principal multivariate should be strengthened using appropriate development strategies/policies to ensure food security and increased farm income for cassava – based farmers in the region.

Path Coefficient Analysis, Character Association and Variability Studies in Selected Maize (Zea mays L.) Genotypes Grown in Southern Nigeria

The success of any selection process is greatly enhanced by using appropriate selection indices. The knowledge of the relationship among various traits affecting grain yield is imperative to arrive at potentially effective selection index. The study was carried out to unveil the different attributes of genetic variability, the type of interrelationships among the various traits affecting yield. Fifteen local and improved maize inbred lines were crossed to three tester varieties to develop 45 test cross progenies. The parents and crosses (63 entries in all) were evaluated in two different locations with three replications at each location using the Randomized complete block design (RCBD). Data generated was recorded for the quantitative traits evaluated and subjected to statistical analysis for estimation of various variability parameters namely GCV, PCV, heritability and genetic advance alongside computing genotypic correlation coefficients and path coefficient analysis to unveil the direct and indirect effects of the various traits studied. The analysis of variability parameters evaluated revealed the presence of significant variability for all the traits studied. Grain yield, ear length, ear height, 100-seed weight and ear diameter showed high GCV estimates, with high heritability. The genetic advance was higher for plant height, ear length, grain/row and grain yield. The genotypic correlation coefficient revealed that ear diameter, 100 seed weight, ear length, kernel rows/ear and grains/row had highest significant correlation with grain yield. The path coefficient analysis revealed that highest direct effect on grain yield was exhibited by 100 seed weight followed by grains/row, kernel rows/ear, ear length and ear diameter. Most of the traits exerted their positive indirect effects through 100 – seed weight, kernel rows/ear and grains/row. The inferences of the results of the present study and their possible implications in maize breeding have been revealed.

Strategies for Mitigating Climate Change Effect on Honey Bee Productivity in Southern Nigeria

This study aimed at determining the educational requirement of Beekeepers in mitigating Climate Change Effects on bee honey production in Obudu Local Government Area of Cross River State, Nigeria. The survey research design was used in achieving this. To adequately and appropriately execute the project three objectives were formulated. From these objectives, research questions were generated and hypotheses formulated accordingly to guide data gathering and analysis. The instrument for data gathering was a four point close ended questionnaire from which 150 farmers and 50 extension agents were selected to respond to items in the questionnaire using the census approach. Data collected from their responses were subjected to two forms of descriptive analysis. The first was percentage descriptive analysis which was used to x-ray the biodata. Second, mean and standard deviation were used to treat the research questions. The third method used is the independent t-test on the three man hypothesis of the study. The result of the analysis warranted the rejection of the three null hypotheses tested at 0.05 level of significance with 198 degrees of freedom using 1.96 as the critical t-value. It was found out that ecological practices of farmers contribute to climate change, climate change has impacted negatively on bee honey production, and farmers should be educated through agricultural extension education in order to become conscious of their practices on natural resources and mitigate climate change effects in bee honey production.

The Impact of Stigma and Discrimination on Adherence to Medication amongst People Living with HIV in Tiv Land, North Central Nigeria

In spite the identification of stigma as a factor impeding public utilisation of HIV counselling, testing, and treatment services in Nigeria, gaps still exist in knowledge on the impact of stigma, and discrimination on adherence to medication amongst people living with HIV (PLWH). This study adopted mixed methods to examine the impact of stigma and discrimination on adherence to medication amongst PLWH in Nigeria.A sample of 1,621 respondents was collected using multi-stage and purposive sampling methods. Structured interviews using questionnaires and in-depth interviews (using a guide) were utilised for data collection. SPSS (version 21) was used for quantitative data analysis while the qualitative data was analysed thematically. There are 46.3% men and 53.7% womenrespondents. Generally, their income is low, 70.7% are earning less than N25, 000 (approximately $125 USD) per month. Some of the HIV patients are stigmatised. In reaction, they avoid publicplaces, travel long distances away from their immediate community to collect drugs andto avoid been noticed around the centers. They sometimes miss taking drugs regularly as prescribed, suffer depression and die. Stigma and discrimination impede adherence to medication amongst PLHW in Nigeria. More efforts should be made to create awareness to reduce stigma and discrimination of HIV patients, while augmenting their income to meet up with the challenges of adherence to medication. The overall benefits would be enhanced mechanism of HIV prevention, treatment and control in the study area

Are antibiotics of any use in the management of granuloma annulare in children?

Background: Granuloma annulare (GA) is a benign inflammatory dermatosis of unknown cause, of which generalised granuloma annulare (GGA) is a subtype that tends to be resistant to treatment. Various antibiotics have been used to treat GGA, the most recent being combination therapy with rifampicin, ofloxacin and minocycline (ROM). This study aims to explore the efficacy of antibiotics in treating GGA, and whether antibiotics may be useful in children with GGA. Materials and Methods: A systematic review of literature published from 1947 to 2017 was undertaken in order to evaluate the use of antibiotics in treating GGA. Data on characteristics of children with GGA were extracted and eligible studies were then qualitatively analysed. Results: Seven hundred and ninety (790) potential studies were identified, of which 16 were eligible for inclusion in the final analysis. Of these 16 studies, majority were case studies (n=9, 56.3%), with 2 case series (12.5%), 2 retrospective studies (12.5%) and 3 open-label prospective studies (18.8%). Main antibiotic treatments reported were either monthly combination therapy of rifampicin, ofloxacin and minocycline (ROM), or monotherapy with dapsone or doxycycline. Out of a total of 158 patients with GA, 72 patients (45.6%) were treated with antibiotics. Of the 72, 48.6% (n=35) of these patients had GGA while 4 were children; two with GA (2 with GGA), all of whom were treated with dapsone. Conclusion: There is paucity of evidence to support the use of antibiotics in the treatment of GGA in children. Although ROM has shown promising results in adults, more studies are needed to validate these findings in children

C2 Fractures in the Elderly: Single-Center Evaluation of Risk Factors for Mortality

STUDY DESIGN: Retrospective cohort study. PURPOSE: The aim of this study was to identify features associated with increased mortality risk in traumatic C2 fractures in the elderly, including measures of comorbidity and frailty. OVERVIEW OF LITERATURE: C2 fractures in the elderly are of increasing relevance in the setting of an aging global population and have a high mortality rate. Previous analyzes of risk factors for mortality have not included the measures of comorbidity and/or frailty, and no local data have been reported to date. METHODS: This study comprises a retrospective review of 70 patients of age >65 years at Waikato Hospital, New Zealand with traumatic C2 fractures identified on computed tomography between 2010 and 2016. Demographic details, medical history, laboratory results on admission, mechanism of injury, and neurological status on presentation were recorded. Medical comorbidities were also detailed allowing calculation of the Charlson Comorbidity Index (CCI) and the modified Frailty Index (mFI). RESULTS: The most common mechanism of injury was a fall from standing height (n=52, 74.3%). Mortality rates were 14.3% (n=10) at day 30, and 35.7% (n=25) at 1 year. Bivariate analysis showed that both CCI and mFI correlated with 1-year mortality rates. Reduced albumin and hemoglobin levels were also associated with 30-day and 1-year mortality rates. Forward stepwise logistic regression models determined CCI and low hemoglobin as predictors of mortality within 30 days, whereas CCI, low albumin, increased age, and female gender predicted mortality at 1 year. CONCLUSIONS: The CCI was a useful tool for predicting mortality at 1 year in the patient cohort. Other variables, including common laboratory markers, can also be used for risk stratification, to initiate timely multidisciplinary management, and prognostic counseling for patients and family members.

Incidence and antibiotic susceptibility pattern of Escherichia coli and Staphylococcus aureus isolated from meat pie sold in a Nigerian North Central town

Background and Objectives: Meat pie is a popular ready-to-eat food sold in Nigeria and is consumed by people of all classes and category. The study aimed to determine the incidence and susceptibility of Escherichia coli and Staphylococcus aureus isolated from meat pie to antibiotics commonly administered in Makurdi.Material and Methods: A total of 180 samples were collected and evaluated for bacterial contamination and presence of antibiotic-resistant Escherichia coli and Staphylococcus aureus. Contaminants were isolated and identified using biochemical test. Antimicrobial susceptibility of isolates was determined using the Kirby-Bauer disc diffusion method.Results: Eleven bacterial genera was identified.  Bacillus spp (85%) occurred most frequently, followed by Staphylococcus aureus (38.9%), while Edwardsiella spp (2.8%) occured the least.  Staphylococcus aureus was highly resistant to Cloxacillin (87.1%) but highly susceptible to Ofloxacin (88.6%).  Escherichia coli was resistant to Amoxycillin, Tetracycline, Cloxacillin and Augmentin but susceptible to Gentamicin and Ofloxacin. Conclusion: Meat pie sold in Makurdi habours Staphylococcus aureus and Escherichia coli with multiple antibiotic resistance. Regulation of the production and retail process of meat pie is advocated as a possible means of reducing contamination and the risk of transferring antibiotic resistant bacteria to consumers.

Haemostatic Disorders in Sickle Cell Disease Subjects in Nigeria: A Review of Literature

Background: Sickle cell disease (SCD) is an autosomal recessive disorder that is characterised with chronic anaemia and painful crisis. SCD is associated with hypercoagulability or prothrombotic state that can predispose to thromboembolic complications with increasing morbidity and mortality. Aim: This study aimed to show the various documented haemostatic disorders and possible thromboembolic complications among SCD subjects in Nigeria. Methods: A comprehensive literature search was performed using the internet search engines linked to academic databases including Pubmed, Google Scholar, Ebsco, Hinari, Scopus, etc. Studies involving hemostatic disorders in Nigeria were thoroughly searched, and the references of such articles were also searched for any probable relevant information. Findings and Conclusion: There is a paucity of information on this subject in Nigeria, and there are inconsistencies in the available studies. Haemostatic disorders in sickle cell disease are conditions that are associated with increased mortality and morbidity. Further research on the level of natural anticoagulant is required to verify the correlation between haemostatic disorders and thromboembolic complications in SCD subjects in Nigeria.

Informal transit, socio-spatial exclusion, and changing geographies of HIV/AIDS in urban Malawi

The role played by the transport sector in the regional spread of HIV in sub-Saharan Africa is well known, yet attention has remained confined to entertainment hotspots and stopping places along long-distance highways and cross-border transport corridors. This paper draws attention to informal modes of transit prevalent in sub-Saharan African cities, by linking the rise of two-wheeled, manually operated bicycles, known as "Sacramento", to the potential spread of HIV and AIDS in Malawi. The findings of a qualitative study from Mzuzu city show that Sacramento operators are prone to demanding or accepting sexual favours from female commuters as payment for a ride. We draw on complementary theories of the political ecology of health (PEH) and feminist political ecology to show how a popular belief that Sacramento is an inferior mode of urban transit underpins risky sexual behaviour among men hired to operate this informal mode transport. The findings further show that operators' responses to this perceived inferiority are themselves also driven by gender discourses that seek to validate their identities as powerful go-getters. These scripts also create an environment that fosters multiple sexual partners and venerates unprotected sex. Because Sacramento is both a source of livelihood and an HIV risk milieu, it epitomises the contraction inherent in HIV and AIDS vulnerability in sub-Saharan Africa
