Lifetime prevalence and knowledge of snakebite among graduates in Nigeria.

BACKGROUND: Given the lack of studies on snakebite envenoming knowledge in the general population, we examined the lifetime prevalence of snakebite and knowledge of snakebite and its prevention and first aid among recent Nigerian graduates in national service. METHODS: This questionnaire-based cross-sectional study involved 351 consenting national youth corps members at a rural orientation camp in Kano, Nigeria. RESULTS: Participants' mean age was 25.3±2.4 y. There were slightly more males (50.7%). Most attended universities (77.8%) and were mainly from the southwest (24.5%) and northeast (24.5%) geopolitical regions and the Yoruba tribe (24.7%). Their lifetime prevalence of snakebite was 4%. Their mean overall knowledge score was 6.8±3.1 out of 20. Only 0.9% had adequate knowledge. Gender (male; 7.2±3.1, t=2.83, p=0.0049), tribe (Yoruba; 7.5±2.9, F=2.968, p=0.0320), region (Southwest; 7.6±3.0, F=2.5289, p=0.0289) and nearly bitten by snake (7.8 ± 2.7, t=3.60, p=0.0004) were significantly associated with a higher mean knowledge score. CONCLUSIONS: Their lifetime prevalence of snakebites is significant, while knowledge of snakebite is very inadequate. However, the national service camp activities period provides an opportunity for educational intervention needed to raise their knowledge to optimal levels that will enable them serve as better snakebite prevention agents, as they will be working in rural communities where snakebite might be prevalent.

Relationship between anaemia, hypoalbuminaemia, and dietary lifestyle of the older adults attending a primary care clinic in Nigeria.

Objectives: To determine the prevalence and severity of anaemia and assess the relationship between dietary lifestyle, hypoalbuminaemia, and anaemia of older persons. Design: A cross-sectional hospital-based study. Setting: This study was conducted in the General Outpatient Clinic, the primary care unit of Aminu Kano Teaching Hospital in Kano, Nigeria. Participants: A total of 378 patients aged ≥ 60 years who presented to the General Out-patient Clinic. Main outcome measures: Prevalence and severity of anaemia, relationship between anaemia and hypoalbuminaemia, and dietary lifestyle of the participants. Results: A total of 348 respondents completed the study. The mean age of respondents was 67.83 ±7.53 years, with female (60.9%) predominance. The prevalence of anaemia and hypoalbuminaemia were 42.2% and 17.8%, respectively. Hypoalbuminaemia (ß=0.335, 95%CI=0.131-0.229, P<0.001), long duration of comorbidities (ß= -0.179, 95%CI= -0.165-0.047, P<0.001), one full meal/day (ß=0.130, 95%CI=0.224-1.879, P=0.013), and low monthly income (ß=0.122, 95%CI=0.179-1.543, P=0.026) were the predictors of anaemia among the older persons in this study. Conclusion: This study revealed a high prevalence of anaemia among older adults. The identified predictors, such as hypoalbuminaemia, long duration of comorbidities, reduced food intake and low monthly income, will be useful in developing guidelines and strategies for managing the condition in primary care settings and other similar sites. Funding: None declared.

Prevalence, severity, and correlates of erectile dysfunction among male adult patients of a primary care clinic in North-West Nigeria.

Background: Erectile dysfunction (ED) is a common sexual problem that profoundly affects intimate relationships. It is poorly studied in North-western Nigeria. Objectives: To assess the prevalence, severity and predictors of ED among adult males attending a primary care clinic in Northwest Nigeria. Methods: A cross-section of 392 males (aged ≥25 years) were randomly selected from attendees of a family medicine clinic in Kano, Nigeria. Information regarding their biodata, lifestyle factors, and clinical characteristics was obtained using a structured questionnaire. The International Index of Erectile Function Questionnaire (version 5) and Patient Health Questionnaire-2 assessed ED and depression, respectively. Results: The participants' mean age was 45±14.1 years (range: 26-86 years). Most participants were married (88.8%), had one sexual partner (71.7%), had tertiary education (44.4%) and were traders (49.7%). The prevalence of ED was 52.3% (205/392) [comprising mild (36.0%), mild-to-moderate (14.3%), moderate (1.5%) and severe (0.5%)]. Age, body mass index (BMI), marital status, number of sexual partners, monthly income, type of exercise, hypertension history, blood pressure reading, antihypertensive and peptic ulcer drug use were associated with ED (P<0.05). However, age (≥50years) (OR= 1.91, 95%CI [1.28-2.85], P=0.001) and overweight/obesity (OR =1.81, 95%CI [1.18-2.77], P=0.007) were the predictors of ED in this population. Conclusion: ED prevalence was high, although mainly of the mild form. Age (≥50years) and overweight/obesity predicted ED. Hence, the need for early screening, objective grading of ED, identification of modifiable risk factors (e.g., overweight/obesity) and commencing proper treatment and prevention in this setting.

Etiology of Persistent Microalbuminuria in Nigeria (P_MICRO study): protocol and study design.

BACKGROUND: Microalbuminuria is an independent risk factor for cardiovascular and kidney disease and a predictor of end organ damage, both in the general population and in persons with HIV (PWH). Microalbuminuria is also an important risk factor for mortality in PWH treated with antiretroviral therapy (ART). In the ongoing Renal Risk Reduction (R3) study in Nigeria, we identified a high prevalence of microalbuminuria confirmed by two measurements 4-8 weeks apart in ART-experienced, virologically suppressed PWH. Although Stage 1 or 2 hypertension and exposure to potentially nephrotoxic antiretroviral medications were common in R3 participants, other traditional risk factors for albuminuria and kidney disease, including diabetes, APOL1 high-risk genotype, and smoking were rare. Co-infection with endemic pathogens may also be significant contributors to albuminuria, but co-infections were not evaluated in the R3 study population. METHODS: In Aim 1, we will cross-sectionally compare the prevalence of albuminuria and established kidney disease risk factors in a cohort of PWH to age- and sex-matched HIV-negative adults presenting for routine care at the Aminu Kano Teaching Hospital in Kano, Nigeria. We will leverage stored specimens from 2500 R3 participants and enroll an additional 500 PLWH recently initiated on ART (≤ 24 months) and 750 age- and sex-matched HIV-negative adults to determine the contribution of HIV, hypertension, and other comorbid medical conditions to prevalent albuminuria. In Aim 2, we will follow a cohort of 1000 HIV-positive, ART-treated and 500 HIV-negative normoalbuminuric adults for 30 months to evaluate the incidence and predictors of albuminuria. DISCUSSION: The findings from this study will support the development of interventions to prevent or address microalbuminuria in PWH to reduce kidney and cardiovascular morbidity and mortality. Such interventions might include more intensive monitoring and treatment of traditional risk factors, the provision of renin-angiotensin aldosterone system or sodium-glucose cotransporter-2 inhibitors, consideration of changes in ART regimen, and screening and treatment for relevant co-infections.

Prevalence and predictors of clinic appointment non-adherence among adults with poorly controlled hypertension in a primary care setting.

Objectives: To assess the prevalence and predictors of non-adherence to clinic appointments in adult patients with poorly controlled hypertension. Design: A descriptive cross-sectional study. Setting: A primary care setting (family medicine clinic) overseen by family physicians in Kano, Nigeria. Participants: Two hundred and thirty-four randomly selected patients, aged ≥ 18 years with a diagnosis of hypertension, who had been on treatment for ≥1 year and had a current blood pressure of ≥140/90 mmHg were included. Main outcome measures: Non-adherence to clinic appointment among participants. Results: Participants' mean age was 55±12.2 years (range: 23-85 years); they were predominantly females (163, 69.7%). Sixty (25.6%) participants were non-adherent to clinic-appointments. Being employed (OR [Odds ratio] =2.92, 95%CI [confident interval] =1.52-5.65, P=0.002), inability of participants or their children to pay the medical bills (OR=2.92,95%CI=1.42-6.00, P=0.004), and systolic blood pressure (SBP) of <160mmHg (OR=0.43, 95%CI=0.22-0.86, P=0.018) were predictors of clinic appointment non-adherence. Conclusions: The prevalence of non-adherence to clinic appointments was high. Being employed, patients or their children's inability to pay medical bills, and higher SBP were predictors of non-adherence to clinic appointments. Therefore, more studies are needed on effective interventions to reduce non-adherence to clinic appointments in this setting.

Knowledge of venomous snakes, snakebite first aid, treatment, and prevention among clinicians in northern Nigeria: a cross-sectional multicentre study.

Background: Snakebite envenoming causes considerable morbidity and mortality in northern Nigeria. The clinician's knowledge of snakebite impacts outcome. We assessed clinicians' knowledge of snakebite envenoming to highlight knowledge and practice gaps for possible intervention to improve snakebite outcomes. Methods: This was a cross-sectional multicentre study of 374 doctors selected from the accident and emergency, internal medicine, family medicine/general outpatient, paediatrics and surgery departments of nine tertiary hospitals in northern Nigeria using a multistage sampling technique. A self-administered questionnaire was used to assess their sociodemographics, knowledge of common venomous snakes, snakebite first aid, snake antivenom treatment and prevention. Results: The respondents' mean age was 35.6±5.8 y. They were predominantly males (70.6%) from urban hospitals (71.9%), from the northwest region (35.3%), in family medicine/general outpatient departments (33.4%), of <10 years working experience (66.3%) and had previous experience in snakebite management (78.3%). Although their mean overall knowledge score was 70.2±12.6%, only 52.9% had an adequate overall knowledge score. Most had adequate knowledge of snakebite clinical features (62.3%), first aid (75.7%) and preventive measures (97.1%), but only 50.8% and 25.1% had adequate knowledge of snake species that caused most injuries/deaths and anti-snake venom treatment, respectively. Overall knowledge predictors were ≥10 y working experience (odd ratio [OR] 1.72 [95% confidence interval {CI} 1.07 to 2.76]), urban hospital setting (OR 0.58 [95% CI 0.35 to 0.96]), surgery department (OR 0.44 [95% CI 0.24 to 0.81]), northwest/north-central region (OR 2.36 [95% CI 1.46 to 3.82]) and previous experience in snakebite management (OR 2.55 [95% CI 1.49 to 4.36]). Conclusions: Overall knowledge was low. Improvements in overall knowledge may require clinicians' exposure to snakebite management and training of accident and emergency clinicians in the region.
