The differential effects of cooking methods on the nutritional properties and quality attributes of meat from various animal sources

This study investigated the various effects of two food product processing methods (boiling and grilling) on the nutritional composition (fatty acid, amino acid profiles) of meat from cows, goats, and rabbits. Freshly slaughtered animals were cleaned and subjected to boiling and grilling. Cooking loss varied with cooking methods; grilling resulted in the highest cooking loss, especially in cow meat (52.95%). Data from the proximate composition analysis revealed that both raw and grilled meat samples of rabbit meat contained the highest amount of protein (22.93 and 22.20 %, respectively) when compared to the corresponding samples from the other two animal sources. Additionally, rabbit meat contained a low level of fat (1.85%), which was not significantly different than the boiled samples (1.75, 1.76 %). Boiling and grilling significantly increased the in vitro protein digestibility of meat. The meat showed significant sources of both essential and non-essential amino acids. Rabbit meat showed a higher proportion of essential amino acids and a higher protein efficiency ratio. Boiled goat meat had a lower proportion of saturated fatty acids (SFA), boiled meat had higher polyunsaturated fatty acids (PUFA) than its grilled counterpart. Goat meat showed a favourable fatty acid profile. Thus, goat and rabbit meat are healthier alternatives to beef, and both boiling and grilling are useful in maintaining the nutritional qualities of meat

Monotherapy with amlodipine or hydrochlorothiazide in patients with mild to moderate hypertension: Comparison of their efficacy and effects on electrolytes

Background: Amlodipine and hydrochlorothiazide (HCTZ) are commonly prescribed in Nigeria either as a monotherapy or in combination with other drugs. The present study was designed to investigate the antihypertensive efficacy of monotherapy with amlodipine or HCTZ and their effects on electrolyte profile in patients with mild to moderate hypertension.Methods: A single-blind randomized clinical study was used; fifty patients newly diagnosed with mild to moderate hypertension (aged 33 to 60 years) were recruited and divided into two groups: amlodipine or hydrochlorothiazide each comprising of 25 subjects. The subjects received 5mg of amlodipine or 25mg of hydrochlorothiazide in their respective group once daily for 4 weeks. Blood pressure, serum and urine electrolytes were measured at baseline and weekly throughout the experiment.Results: At the end of follow up, amlodipine reduced systolic and diastolic blood pressure significantly more (p<0.001) than HCTZ. At the end of follow up, blood pressure was reduced to normal in 80% of the subjects in amlodipine group compared to 50% in HCTZ. Amlodipine had no significant effect on electrolyte profile of subjects unlike HCTZ which significantly changed both their serum and urine electrolytes.Conclusions: Monotherapy with amlodipine was more effective than HCTZ in black patients with mild to moderate hypertension and in addition maintained electrolyte balance

The Interference of Politicians in the Recruitment and Selection of Academic Staff in Tertiary Institutions: A Case Study of Polytechnics in Niger Delta

The purpose of this paper was to investigate the interference of politicians in the recruitment and selection of academic staff in federal polytechnics in Niger delta. The research design was descriptive survey to investigation and observed the influence of politicians on recruitment and selection of academic staff  in federal polytechnics  in the Niger delta region of Nigeria .It is of  utmost important for  institutions within this region to discourage the interference of political office holders in the recruitment and selection processes for  these polytechnics to avoid having unqualified staff and poor performing students .Findings from the research shows that the quality of graduates  depends on the quality of the academic staff piloting the academic field of the institutions. Also unqualified staff are recruited and appointed to hold sensitive academic position in the polytechnics thereby ridiculing the meritocracy system.  Sequel to the above , it is very important for this institutions ensure that quality academic staff  of the schools are being properly recruited and selected  not appointed by politicians since this  has a negative effect both on  the image and academic performance of the polytechnics .Some recommendations were put forward to resolve the issues of the research

ECG abnormalities among HIV infected children placed on ART at Enugu, South East of Nigeria

Background: Cardiovascular abnormalities are not much reported among human immunodeficiency virus (HIV) infected children especially in Africa where there is high HIV disease. In addition, the use of highly active antiretroviral therapy (HAART) in such children may have a protective effect on the cardiovascular system. Methods: Cross-sectional study of randomly selected eighty HIV infected and 80 aged matched non- HIV-infected children were used. HIV-infected children were on HAART for more than 5years and had steadily received the treatment for 6 months prior to the time of the tests. Heights and weights were measured and body mass index calculated. Cardiac indices evaluated were heart rate (HR), PR interval, QRS duration, QT/QTC Interval, P/QRS/T Axis, RV5/SV1 voltage and RV5+SV1 voltage. Results: The average heart rate was significantly higher among HIV infected children on HAART than their non-infected counterparts (P= 0.019). At 0.05 significance level, their PR interval was significantly higher than those in the control group (P=0.050). The average QRS duration result also showed a significant difference between that of test and control subjects (P = 0.022) Conclusion: The HAART usage possibly improved the cardiovascular functioning in the infected children but the protective effects diminish with increase age and longer exposur

Expanding youth-friendly HIV self-testing services during the COVID-19 pandemic: Qualitative analysis of a crowdsourcing open call in Nigeria

BACKGROUND: HIV self-testing (HIVST) among young people is an effective approach to enhance the uptake of HIV testing recommended by the World Health Organization. However, the COVID-19 pandemic disrupted conventional facility-based HIV testing services, necessitating the exploration of innovative strategies for the effective delivery of HIVST. OBJECTIVE: This study analyzed the outcomes of a digital World AIDS Day crowdsourcing open call, designed to elicit youth responses on innovative approaches to promote HIVST among young people (14-24 years) in Nigeria during COVID-19 restrictions. METHODS: From November 2 to 22, 2020, a World AIDS Day 2020 crowdsourcing open call was held digitally due to COVID-19 restrictions. The crowdsourcing open call followed World Health Organization standardized steps, providing a structured framework for participant engagement. Young people in Nigeria, aged 10-24 years, participated by submitting ideas digitally through Google Forms or email in response to this crowdsourcing open call prompt: How will you promote HIV self-testing among young people during COVID-19 pandemic? Data and responses from each submission were analyzed, and proposed ideas were closely examined to identify common themes. Four independent reviewers (AE, SM, AZM, and TG) judged each submission based on the desirability, feasibility, and impact on a 9-point scale (3-9, with 3 being the lowest and 9 being the highest). RESULTS: The crowdsourcing open call received 125 eligible entries, 44 from women and 65 from men. The median age of participants was 20 (IQR 24-20) years, with the majority having completed their highest level of education at the senior secondary school level. The majority of participants lived in the South-West region (n=61) and Lagos state (n=36). Of the 125 eligible entries, the top 20 submissions received an average total score of 7.5 (SD 2.73) or above. The panel of judges ultimately selected 3 finalists to receive a monetary award. Three prominent themes were identified from the 125 crowdsourcing open call submissions as specific ways that HIVST can adapt during the COVID-19 pandemic: (1) digital approaches (such as gamification, photoverification system, and digital media) to generate demand for HIVST and avoid risks associated with attending clinics, (2) awareness and sensitization through existing infrastructures (such as churches, schools, and health facilities), and (3) partnerships with influencers, role models, and leaders (such as religious and youth leaders and social influencers in businesses, churches, organizations, and schools) to build trust in HIVST services. CONCLUSIONS: The crowdsourcing open call effectively engaged a diverse number of young people who proposed a variety of ways to improve the uptake of HIVST during the COVID-19 pandemic. Findings contribute to the need for innovative HIVST strategies that close critical knowledge and practice gaps on ways to reach young people with HIVST during and beyond the pandemic.

Preparation Methods and Clinical Outcomes of Platelet-Rich Plasma for Intra-articular Hip Disorders: A Systematic Review and Meta-analysis of Randomized Clinical Trials.

Background: Despite its increasing use in the management of musculoskeletal conditions, questions remain regarding the preparation methods of platelet-rich plasma (PRP) and its clinical applications for intra-articular hip disorders, including femoroacetabular impingement syndrome (FAIS), labral pathology, and osteoarthritis (OA). Purpose: To systematically review and assess the preparation methods and clinical outcomes from randomized clinical trials (RCTs) on the use of PRP for intra-articular hip disorders. Study Design: Systematic review; Level of evidence, 2. Methods: A systematic review in accordance with the 2009 PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines was performed in September 2019. The Cochrane Database of Systematic Reviews, Cochrane Central Register of Controlled Trials, PubMed, Ovid Medline, and Embase were queried for studies regarding the use of PRP to treat intra-articular hip disorders. Qualifying articles were English-language RCTs describing the use of PRP for intra-articular hip disorders, either as standalone treatment or surgical augmentation. Two authors independently assessed article eligibility. Data pertaining to patient characteristics, indication for treatment, PRP preparation method, follow-up period, and clinical outcomes were extracted. Study results were qualitatively reported and quantitatively compared using meta-analysis when appropriate. Results: Seven RCTs met inclusion criteria. Four studies described the use of PRP for hip OA and 3 utilized PRP at arthroscopy for FAIS and labral tears. Outcomes after PRP for OA demonstrated improvement in validated patient-reported outcome measures for up to 1 year; however, pooled effect sizes found no statistically significant difference between PRP and hyaluronic acid (HA) regarding pain visual analog scale scores at short-term (≤2 months; P = .27), midterm (4-6 months; P = .85), or long-term (1 year; P = .42) follow-up. When injected at arthroscopy, 1 study reported improved outcomes, 1 reported no difference in outcomes, and 1 reported worse outcomes compared with controls. The meta-analysis demonstrated no statistically significant difference on the modified Harris Hip Score (mHHS) between PRP and control cohorts at a minimum 1-year follow-up. There were considerable deficiencies and heterogeneity in the reporting of PRP preparation methods for both indications. Conclusion: Treatment of OA with PRP demonstrated reductions in pain and improved patient-reported outcomes for up to 1 year. However, there was no statistically significant difference between PRP and HA in pain reduction. Likewise, for FAIS and labral surgery there was no statistically significant difference in mHHS outcomes between patients treated with PRP and controls. Given the limited number of studies and variability in PRP preparations, additional high-quality randomized trials are warranted

Methodology and reporting quality of 544 studies related to ageing: a continued discussion in setting priorities for ageing research in Africa

# Background The quality assessment provides information on the overall strength of evidence and methodological quality of a research design, highlighting the level of confidence the reader should place on the findings for decision making. This paper aimed to assess the quality (methodology and quality of reporting) of ageing studies in Sub-Saharan Africa (SSA). # Method This paper is the second of a Four-Part Series paper of a previous systematic mapping review of peer-reviewed literature on ageing studies conducted in SSA. We updated the literature search to include additional 32 articles, a total of 544 articles included in this paper. Downs & Black checklist, Case Report guidelines checklist, the 45-items Lundgren et al. checklist, and the Mixed Method Appraisal Tool were used to assess the methodological quality of quantitative, case reports, qualitative, and mixed-method studies. Quality assessment was piloted and conducted in pairs for each study type. Depending on the checklist, each study was classified as excellent, good, fair, or poor. # Result Of the 544 articles, we performed the quality assessment of a total of 451 quantitative studies $$Randomized control trials (RCTs) and pre-post (n=15), longitudinal (n=122), case-control (n=15) and cross-sectional (n=300); 4 case reports, 74 qualitative and 15 mixed-method studies. Only 20.4$$. The remaining 433 were rated as moderate quality (n=292, 53.7%), fair quality (n = 96, 17.7%) and poor quality (n = 45, 8.2%). Most (80%) quantitative articles' sample size is small, resulting in insufficient power to detect a clinically or significant important effect. Three-quarter (75%) of the qualitative studies did not report their research team characteristics and a reflexivity component of the 45-items Lundgren et al. checklist. Mixed-method studies with low quality did not report the qualitative studies properly. # Conclusion We conclude that the methodological and quality reporting of published studies on ageing in SSA show variable quality, albeit primarily moderate quality, against high quality. Studies with a large sample size are recommended, and qualitative researchers should provide a section on research team members' characteristics and reflexivity in their paper or as an appendix
