Prevalence of Kidney Dysfunction and Associated Risk Factors in a Southwestern City in Nigeria: A Cross-Sectional Study

BACKGROUND

The burden of chronic kidney disease (CKD) is huge, especially in countries such as Nigeria where majority of patients succumb to the disease early due to inability to afford care. Early diagnosis through regular screening of at-risk population is pivotal to stemming the scourge of the disease.

AIM

To determine the prevalence of kidney dysfunction and associated risk factors in a community screening program.

METHODS

This cross-sectional study assessed kidney dysfunction and associated risk factors among adults in Ondo City, Nigeria. Information about socio-demographic characteristics and some risk factors for kidney dysfunction was sought. Blood pressure, weight and height were measured. Blood samples were collected for random blood glucose check and serum creatinine while urine sample was collected for urinalysis. Kidney dysfunction was defined by estimated glomerular filtration rate (eGFR) below 60mls/min/1.73m2. Prevalence of kidney dysfunction and associated factors were determined. P value<0.05 was taken as significant.

RESULTS

There were 410 participants with a mean age of 58.96±13.78 years. Majority (75.1%) were female. One hundred and forty-seven (35.9%) participants had kidney dysfunction. Identified risk factors for kidney dysfunction were hypertension (72.7%), diabetes mellitus (18.0%), alcohol intake (13.2%), tobacco smoking (2%), analgesic use (82.7%), use of herbal preparations (81.7%), proteinuria (6.1%), overweight (27.8%), generalized obesity (28.5%), and central obesity (33.9%). Significant factors associated with kidney dysfunction were older age (p=<0.001), lower level of education (p=<0.001), and being hypertensive (p=0.019). On binary logistic regression, older age (AOR: 9.14; CI: 3.68-22.7; p=<0.001) was the only significant factor associated with kidney dysfunction.

CONCLUSION

The prevalence of kidney dysfunction and that of associated risk factors were relatively high in the screened population. Regular assessment of kidney function should be done in those with higher risk of kidney dysfunction, especially older patients with hypertension.

Task Sharing and Task Shifting (TSTS) in the Management of Africans with Hypertension: A Call For Action-Possibilities and Its Challenges

Hypertension is a leading cause of mortality globally and one of the most common risk factors for cardiovascular disease. Diagnosis, awareness, and optimal treatment rates are suboptimal, especially in low- and middle-income countries, with attendant high health consequences and grave socioeconomic impact. There is an enormous gap between disease burden and physician-patient ratios that needs to be bridged. Task sharing and task shifting (TSTS) provide a viable temporary solution. However, sociocultural, demographic, and economic factors influence the effective uptake of such interventions. This review discusses the dynamics of TSTS in the African context looking at challenges, feasibility, and approach to adopt it in the management of hypertension in Africa.

First and Second Waves of Covid-19: A Comparative Study of the Clinical Presentation and Outcome among Hospitalized Patients in Lagos Nigeria

OBJECTIVE

Nigeria experienced many waves of the COVID-19 pandemic. This study compared the clinical presentations and mortality among hospitalized patients during the first and second waves of the pandemic in Lagos State, Nigeria.

METHODS

A retrospective cohort study was conducted. Deidentified medical records of laboratory-confirmed COVID-19 patients admitted into 15 isolation centers in Lagos, Nigeria between February 27, 2020, and September 30, 2020 (first wave) and October 1, 2020, and April 30, 2021 (second wave) were reviewed. IBM Statistics version 25 was used for data analysis.

RESULTS

More patients were hospitalized during the first wave of the pandemic. The mean age of patients was higher during the second wave (54.5±15.8 years vs. 42.2±15.5 years, p <0.001). More patients admitted during the second wave had comorbidities (56.0% vs 28.6%, p <0.001), were symptomatic (90.8% vs 52.0%, p <0.001), had severe COVID-19 disease (58.9% vs 25%, p <0.001) and died (14.9% vs 6.4%, p<0.001) compared with the first wave. The odds of death increased with age and severity of COVID-19 disease during the first and second waves.

CONCLUSION

A higher proportion of the patients admitted in Lagos, Nigeria during the second wave were older, had comorbidities, and had severe COVID-19 disease than the first wave. Despite the fewer hospitalized patients, there were more deaths during the second wave.

Sleep quality and associated factors among patients with chronic kidney disease in Nigeria: a cross-sectional study

OBJECTIVE

Poor sleep quality adversely affects the overall well-being and outcomes of patients with chronic kidney disease (CKD). However, it has not been well studied in Africans with CKD. We determined the prevalence of poor sleep quality and associated factors among patients with CKD.

DESIGN

This was a cross-sectional study that involved patients with CKD .

SETTINGS

The study was carried out in the outpatient clinic of nine hospitals in Nigeria.

METHODS

Sleep quality, depressive and anxiety symptoms and quality of life (QoL) were assessed among 307 patients with CKD using Pittsburgh Sleep Quality Index Questionnaire, Hospital Anxiety Depression Scale Questionnaire and 12-item Short Form Health Survey Quality of Life Questionnaire, respectively. The prevalence of poor sleep quality and associated factors were determined. A p<0.05 was considered as statistically significant.

RESULTS

The mean age of the study participants was 51.40±15.17 years. The male:female ratio was 1.5:1 One hundred and twenty-one (39.4%) of the patients were on maintenance haemodialysis (MHD). The prevalence of poor sleep quality, anxiety symptoms and depressive symptoms among the patients was 50.2%, 37.8% and 17.6%, respectively. The prevalence of poor sleep quality in the CKD stages 3, 4, 5 and 5D was 38.1%, 42.6%, 52.2% and 58.7%, respectively. The prevalence of poor sleep quality was significantly higher in MHD patients compared with predialysis CKD (59.5% vs 43.6%; p=0.008). Factors associated with poor sleep quality were CKD stage (p=0.035), anaemia (p=0.003), pruritus (p=0.045), anxiety symptoms (p≤0.001), depressive symptoms (p≤0.001) and reduced QoL (p≤0.001). On multivariate analysis, factors associated with poor sleep were anxiety (AOR 2.19; 95% CI 1.27 to 3.79; p=0.005), anaemia (AOR 5.49; 95% CI 1.43 to 21.00;p=0.013) and reduced physical component of QoL (AOR 4.11; 95% CI 1.61 to 10.47; p=0.003).

CONCLUSION

Poor sleep quality is common among patients with CKD especially in the advanced stage. The significant factors associated with poor sleep quality were QoL, anaemia and anxiety symptoms. These factors should be adequately managed to improve the overall outcomes of patients with CKD.

Relationship between Kidney Dysfunction, Stroke Severity, and Outcomes in a Nigerian Tertiary Hospital: A Prospective Study

BACKGROUND

Stroke is a common neurologic disease associated with fatal outcomes. Kidney dysfunction may be an important predictor of stroke severity and outcome.

AIM

To determine the relationship between kidney dysfunction at admission and stroke severity and 30-day outcome.

MATERIALS AND METHODS

This was a prospective study that involved 150 stroke patients. Stroke severity at admission was assessed using the National Institutes of Health Stroke Scale (NIHSS). Renal dysfunction was assessed by the presence of albuminuria and or reduced glomerular filtration rate (GFR) at admission. Neurological outcome was assessed using mortality, modified Rankin Scale (mRS), and Glasgow Outcome Scale (GCS).

RESULTS

The mean age of the study participants was 61.0 ± 13.2 years. Renal dysfunction was present in 66% of the participants while the case fatality rate of stroke was 26%. Poor neurological outcome at 30 days was found in 44.1% of survivors. Those with albuminuria had lower GCS (P = 0.041), lower GFR (P = 0.004), higher mRS score on day 14 (P = 0.041) and day 30 (P = 0.032), and higher NIHSS score (P = 0.034). Independent predictors of 30-day mortality were albuminuria (Adjusted Odd Ratio (AOR) 3.60, 95%CI: 1.07-12.17) and increasing NIHSS score (AOR = 1.15, 95%CI: 1.04-1.28). Lower GCS (P < 0.001), elevated white blood cells (P = 0.003), serum creatinine (P = 0.048), and NIHSS score (P < 0.001) were associated with poor neurological outcome. NIHSS score was the only significant predictor of neurologic outcome (AOR: 1.25; CI: 1.11-1.41; P ≤ 0.001).

CONCLUSIONS

Kidney dysfunction was associated with stroke severity and mortality. However, it was not an independent predictor of neurological outcome.

Cardiovascular risk factors and kidney function among automobile mechanic and their association with serum heavy metals in Southwest Nigeria: A cross-sectional study

INTRODUCTION

The burden of cardiovascular disease (CVD) is huge due to its associated morbidity, mortality and adverse socio-economic impact. Environmental pollution as a risk factor contributes significantly to the burden of CVD, especially in the low and middle income countries. One of the effective strategies to reduce CVD burden is to prevent or detect cardiovascular risk factors early in at-risk population. This study determined some cardiovascular risk factors, kidney function, and their association with heavy metals among automobile mechanics.

METHOD

This was a cross-sectional study involving 162 automobile mechanics and 81 age and sex matched controls. Serum levels of lead, cadmium and some cardiovascular risks were assessed and compared in the two groups. Associations between serum lead, cadmium and some cardiovascular risks were determined using correlation analysis. P value of <0.05 was taken as significant.

RESULTS

The mean ages of the automobile mechanics and controls were 47.27±9.99 years and 48.94±10.34 years, respectively. The prevalence of elevated serum cadmium was significantly higher in the automobile mechanics (25.9% vs 7.9%; p = <0.001). The significant cardiovascular risk factors in the automobile mechanics vs controls were elevated total cholesterol (32.1% vs 18.5%; p = 0.017), hyperuricemia (20.4% vs 1.2%; p = <0.001), elevated blood glucose (16.0% vs 4.9% p = 0.013); and alcohol use (55.1% vs 30.0%; p = 0.001). Among the automobile mechanics, there were significant positive correlations between serum cadmium, atherogenic index of plasma (AIP) (p = 0.024; r = 0.382) and triglyceride (p = 0.020; r = 0.391). Significant positive correlation was found between serum lead and neutrophil gelatinase associated lipocalin (NGAL) (p = <0.001; r = 0.329). There were significant positive correlation between serum cadmium level, AIP (p = 0.016; r = 0.373) and TG (p = 0.004; r = 0.439); between serum lead and NGAL in all the study participants (p = 0.005; r = 0.206).

CONCLUSION

Automobile mechanics have notable exposure to heavy metals and a higher prevalence of some cardiovascular risk factors. Health education and sensitisation as well as policies that would regulate exposure of persons to heavy metals should be implemented in Nigeria.

Physicians' perception of task sharing with non-physician health care workers in the management of uncomplicated hypertension in Nigeria: A mixed method study

INTRODUCTION

Task sharing and task shifting (TSTS) in the management of hypertension is an important strategy to reduce the burden of hypertension in low-and middle-income countries like Nigeria where there is shortage of physicians below the World Health Organization's recommendations on doctor-patient ratio. The cooperation of physicians is critical to the success of this strategy. We assessed physicians' perception of TSTS with non-physician health workers in the management of hypertension and sought recommendations to facilitate the implementation of TSTS.

MATERIALS AND METHODS

This was an explanatory sequential mixed method study. TSTS perception was assessed quantitatively using a 12-item questionnaire with each item assigned a score on a 5-point Likert scale. The maximum obtainable score was 60 points and those with ≥42 points were classified as having a good perception of TSTS. Twenty physicians were subsequently interviewed for in-depth exploration of their perception of TSTS.

RESULTS

A total of 1250 physicians participated in the quantitative aspect of the study. Among the participants, 56.6% had good perception of TSTS in the management of hypertension while about two-thirds (67.5%) agreed that TSTS program in the management of hypertension could be successfully implemented in Nigeria. Male gender (p = 0.019) and working in clinical settings (p = 0.039) were associated with good perception. Twenty physicians participated in the qualitative part of the study. Qualitative analysis showed that TSTS will improve overall care and outcomes of patients with hypertension, reduce physicians' workload, improve their productivity, but may encourage inter-professional rivalry. Wide consultation with stakeholders, adequate monitoring and evaluation will facilitate successful implementation of TSTS in Nigeria.

CONCLUSION

This study showed that more than half of the physicians have good perception of TSTS in hypertension management while about two-thirds agreed that it could be successfully implemented in Nigeria. This study provides the needed evidence for increased advocacy for the implementation of TSTS in the management of hypertension in Nigeria. This will consequently result in improved patient care and outcomes and effective utilization of available health care personnel.

Protein energy wasting in pre-dialysis chronic kidney disease patients in Benin City, Nigeria: A cross-sectional study

INTRODUCTION

Protein energy wasting (PEW) is common among chronic kidney disease (CKD) patients, especially those with advanced stage. It worsens frailty, sarcopenia and debility in CKD patients. Despite the importance of PEW, it is not routinely assessed during management of CKD patients in Nigeria. The prevalence of PEW and its associated factors were determined in pre-dialysis CKD patients.

METHODS

This was a cross-sectional study that involved 250 pre-dialysis CKD patients and 125 age- and sex- matched healthy controls. Body mass index (BMI), subjective global assessment (SGA) scores and serum albumin levels were used in PEW assessment. The factors associated with PEW were identified. P-value of < 0.05 was taken as significant.

RESULTS

The mean age of CKD and control group were 52.3±16.0 years and 50.5±16.0 years, respectively. The prevalence of low BMI, hypoalbuminaemia and malnutrition defined by SGA in pre-dialysis CKD patients were 42.4%, 62.0% and 74.8%, respectively. The overall prevalence of PEW among the pre-dialysis CKD patients was 33.3%. On multiple logistic regression, the factors associated with PEW in CKD were being middle aged (adjusted odds ratio: 12.50; confidence interval: 3.42-45.00; p <0.001), depression (adjusted odds ratio: 2.34; confidence interval: 1.02-5.40; p = 0.046) and CKD stage 5 (adjusted odds ratio: 12.83; confidence interval: 3.53-46.60; p <0.001).

CONCLUSION

PEW is common in pre-dialysis CKD patients and it was associated with middle age, depression and advanced CKD. Early intervention aimed at addressing depression in early stages of CKD may prevent PEW and improve overall outcome in CKD patients.

Determinants of Interest in Nephrology Career Choice among Internal Medicine Junior Residents in Nigeria

INTRODUCTION

There has been decreased interest in postgraduate nephrology training over the years. This trend could worsen the shortage of nephrologists and inability to meet the health needs of patients with kidney diseases if not urgently addressed.

AIM

To determine interest in and determinants of nephrology career choice among junior internal medicine residents in Nigeria.

METHODOLOGY

This was a cross-sectional study that enrolled 273 junior residents in internal medicine across Nigeria. A self-administered questionnaire that was adapted from two previous studies was used for data collection.

RESULTS

The mean age of the respondents was 33.6±4.4 years with a male: female ratio of 1.8:1. This study showed that 16.8% and 21.6% of junior residents in internal medicine considered nephrology as their first and second choice area to specialize, respectively. Factors that ranked high as determinants of a decision to do nephrology were personal interest (94.3%), opportunities to perform renal procedures (93.3%), and exposure to nephrology training (85.7%). Factors that discouraged a choice of nephrology according to respondents were high mortality of renal patients (67.3%), poor outcomes of renal patients (70.2%), in ability to fund treatment by renal patients (66.1%), unsatisfactory life-work balance among nephrologists (60.7%), and late presentation of renal patients (59.0%). Others were high workload compared to available doctors (59.0%) and poor job satisfaction (55.4%). Factors that could stimulate more interest in nephrology according to respondents included creation of better working environment with adequate equipment for training (96.3%), provision of health insurance with adequate coverage for renal patients (97.4%), and increased government support for renal care services (99.3%).

CONCLUSION

There is a need to promote and sustain interest of residents in nephrology by ensuring improved survival of patients through better access to renal care, ensuring an adequate and well motivated work force, provision of adequate facilities and health insurance services.

Malnutrition in elderly patients with type 2 diabetes mellitus in a Nigerian tertiary hospital: A cross-sectional study

Introduction

The global population of the elderly with type 2 diabetes mellitus (T2DM) is growing due to improvement in DM care and increased life expectancy. Malnutrition is a recognized complication of DM especially in the elderly. However, despite the impact of malnutrition on the overall outcome of the elderly with DM, it has not received adequate attention.

Aim

To determine the prevalence of malnutrition and associated factors in the elderly with T2DM.

Methods

This was a cross-sectional study that involved 96 elderly with T2DM and 96 age and sex matched elderly without T2DM as controls. Malnutrition was assessed using mini-nutritional assessment-short form (MNA-SF), hypoalbuminemia and body mass index (BMI). The factors associated with some malnutrition indices were determined.

Results

The mean age of T2DM and non-T2DM groups were 66.73 ± 5.18 years and 66.78 ± 5.25 years respectively. The observed malnutrition indices among elderly with T2DM and controls were hypoalbuminemia (79.2% vs 25.0%; P ≤0.001); overweight and obesity (58.3% vs 24.0%); and underweight (16.7% vs 4.2%). According to MNA-SF, malnutrition (7.3% vs 0%) and at risk of malnutrition (42.7% vs 16.7%) were significantly more prevalent among elderly with T2DM compared to controls (P ≤0.001). On logistic regression, the significant predictors of malnutrition were male gender (AOR:2.70; CI:1.11-6.55; P = 0.028) and albuminuria (AOR:3.14; CI:1.18-8.35; P = 0.022) and poor glycemic control (AOR:7.05; CI:2.01-24.71; P = 0.002).

Conclusion

Malnutrition is highly prevalent in elderly with T2DM. Poor glycemic control, albuminuria and male gender were significant predictors of malnutrition in this study. Nutritional assessment should be included in the routine DM care especially among the elderly.

Seek and you shall find—retrieval of a retained fractured intravenous cannula by Z-plasty incision: a case report

Peripheral venous cannulation is a common invasive procedure. Fracture of an intravenous cannula is rare and an under-reported complication of peripheral venous cannulation. Embolization of the intravenous fragment into the central venous system is potentially fatal. Urgent surgical retrieval, which is performed through a transverse or longitudinal incision, is the treatment of choice. We herein present the use of Z-plasty incision for the retrieval of a retained fractured peripheral intravenous cannula in a 61-year-old Nigerian man on hemodialysis for chronic kidney disease. The major benefits of this innovation are facilitation of access for exploration and prevention of joint contracture.

Prevalence of cardiovascular risk factors and their association with renal impairment in elderly patients with type 2 diabetes mellitus in a Nigerian tertiary hospital: a cross-sectional study

Introduction

the population of elderly with Type 2 Diabetes Mellitus (T2DM) has been on the increase. The burden of cardiovascular disease and renal impairment may also increase due to the relationship between cardiovascular risk factors and ageing in those with T2DM. The prevalence of cardiovascular risk factors and their association with renal impairment in elderly with T2DM were determined.

Methods

this is a cross-sectional study that involved 96 elderly patients with T2DM and 96 elderly individuals without DM as control. The prevalence of cardiovascular risk factors was determined among the study participants. Binary logistic regression was used to determine the significant cardiovascular factors associated with renal impairment among the elderly with T2DM. P-value <0.05 was taken as significant.

Results

the mean age of the elderly with T2DM and control group were 66.73±5.18 years and 66.78±5.25years, respectively. The male: female ratio was 1: 1 for both groups. The prevalence of the cardiovascular risk factors in the elderly with T2DM and control were; hypertension (72.9%vs39.6%; p ≤0.001), high glycated haemoglobin (77.1% vs 0%; p ≤0.001), generalized obesity (34.4%vs1.0%; p ≤0.001), central obesity (50.0%vs11.5%; p ≤0.001), dyslipidemia (97.9%vs89.6%; p=0.016), albuminuria (69.8% vs 11.2%; p ≤0.001), anaemia (53.1%vs18.8%; p ≤0.001). Renal impairment was present in 44.8% of the elderly T2DM. On multivariate analysis, the cardiovascular risk factors significantly associated with renal impairment in elderly with T2DM were high glycated haemoglobin (aOR: 6.21, 95% CI: 1.61-24.04; p=0.008), albuminuria (aOR: 4.77, 95% CI: 1.59-14.31; p=0.005) and obesity (aOR: 2.78, 95%CI 1.04-7.45; p=0.042).

Conclusion

cardiovascular risks factors were highly prevalent and closely associated with renal impairment in elderly with T2DM. Early cardiovascular risk factor modification may reduce both renal and cardiovascular disease burden.

Prevalence and Correlates of Suicidal Ideation among Medical Students in a Tertiary Institution in Southern Nigeria

INTRODUCTION

Medical students have an increased risk of suicidal ideation compared to similar age groups within the general population. Suicidal ideation is a significant predictor of suicidal attempt, therefore, identifying and addressing factors associated with suicidal ideation among medical students may potentially reduce their overall rates of suicide.

AIM

To determine the prevalence and correlates of suicidal ideation among medical students in a Nigerian medical school.

METHODOLOGY

This was a cross-sectional study that determined the prevalence and correlates of suicidal ideation among clinical students. Beck's suicidal ideation questionnaire, Beck's depression inventory and World Health Organisation Alcohol Smoking and Substance Involvement Screening Test (ASSIST) were used to assess for suicidal ideation, depression and lifetime substance use respectively. P value of <0.05 was taken as significant.

METHODOLOGY

This was a cross-sectional study that determined the prevalence and correlates of suicidal ideation among clinical students. Beck's suicidal ideation questionnaire, Beck's depression inventory and World Health Organisation Alcohol Smoking and Substance Involvement Screening Test (ASSIST) were used to assess for suicidal ideation, depression and lifetime substance use respectively. P value of <0.05 was taken as significant.

RESULTS

One hundred and twenty-one students participated in the study. Mean age of the participants was 21.78±3.54 years. The prevalence of suicidal ideation was 12.4%. Factors associated with suicidal ideation were intimate relationship problems (p=0.03); being managed for a chronic medical condition (p=0.02); higher depression scores (p<0.001); and having fewer maternal siblings (p=0.02). Forty-five (37.2%) students had a life time use of psychoactive substances which was mainly alcohol.

CONCLUSION

Suicidal ideation was relatively high among the medical students. Medical schools should create programmes that will cater for the emotional and psychological wellbeing of their students to reduce their suicidal risk.

Type 2 diabetes mellitus risk assessment among doctors in Ondo state

Introduction

Diabetes Mellitus (DM) has become a disease of public health importance in Nigeria. Early identification of DM risk is important in the reduction of this disease burden. This study assessed ten-year risk of developing type 2 DM among some medical doctors in Ondo State.

Methods

This was a cross-sectional study that assessed ten-year risk of developing type 2 DM among some doctors using the Finland Diabetic Risk Score form. Known diabetics were excluded from the study. Body mass index (BMI), waist circumference (WC), blood pressure and total DM risk score were determined for each participant.

Results

One hundred and ninety-two doctors participated in the study with a male: female ratio of 1.3:1. Majority (92.2%) were below 55 years, 22 (11.5%) were obese, 32(16.7%) had central obesity, 46(24%) reported physical inactivity, 49(25.5%) had family history of DM, 141(73.4%) do not take fruits and vegetables regularly. Forty-three (22.4%) were found to have elevated blood pressure while 6(3.1%) had elevated blood glucose. Fifty-seven (29.7%) of the participants had increased ten-year DM risk. Significant predictors of increase DM risk were age ≥ 45 years (AOR:9.08; CI 3.13–26.33; p = <0.001); BMI ≥25kg/m² (AOR:11.41; CI:4.14–31.45; p = <0.001); family history of DM (AOR:9.93; CI:3.25–30.39; p = <0.001); abdominal obesity (AOR:6.66; CI:2.08–21.29; p= < 0.001); and infrequent dietary intake of fruits and vegetable (AOR:3.11;CI:1.03:9.37: p = 0.04)

Conclusion

There was increased 10-year DM risk in about 30% of the participants. Lifestyle modification such as physical activity and regular consumption of fruits and vegetables should be encouraged among doctors.

Recalling the universal health coverage vision and equity in the COVID-19 vaccine distribution plan

The COVID-19 pandemic has changed the world in so many ways since 2019 when the first case was recorded. COVID-19 pandemic has impacted negatively on economy, health, education and infrastructure globally. COVID-19 vaccine was developed with the aim of stopping the pandemic and allowing the rebuilding of our societies and economies. The vaccine was rolled out in December 2020 and the distribution plan appears to be skewed in favour of high income countries. This paper highlights the need for consideration of the principles of equity and universal health coverage in the distribution plan of the vaccine. It emphasizes the need to ensure that the interests of citizens of developing and low income countries are well protected. The paper concludes that issues of disparity in economic status of countries entering agreement with the vaccine manufacturing companies, absence of logistic support among others should not be a barrier to ensuring equitable access to vaccine for all consistent with the sustainable development goal 3.7.

Prevalence of sickle cell trait and its association to renal dysfunction among blood donors at University of Medical Sciences Teaching Hospital, Ondo, Nigeria

Introduction

Prospective blood donors are routinely screened for blood borne infections but medical illnesses and haemoglobin genotype are overlooked despite a high prevalence of haemoglobin AS among Nigerian donors.

Objective

To determine the prevalence of haemoglobin AS and its association to renal function, if any.

Method

Apparently healthy donors were studied between February and December 2018. Their haemoglobin genotype and, estimated glomerular filtration rates were determined.

Results

There were 96 males (94.1%) and 6 (5.9%) females with mean age of 26.7±4.5 years (range 19–44 years) and mean eGFR of 103.97±19.00ml/min/1.73m2. Eighty one (79.4%) and 21 (20.6%) subjects had haemoglobin AA and AS genotypes respectively. The mean eGFR for subjects with haemoglobin AA and AS were 105.2±18.6ml/min/1.73m² and 99.9 ± 21.2ml/min/1.73m² respectively (p value = 0.270). Eighty one (79.4%), 20 (19.6%) and 1 (1.0%) subjects had renal function at >90ml/min/1.73m², 60–89ml/min/1.73m² and 30–59ml/min/m² respectively. There was no significant difference in the mean eGFR between subjects with haemoglobin AA and AS (mean difference 5.3, p = 0.265, 95%CI = -4.07 to 14.60).

Conclusion

The prevalence of sickle cell trait among Nigerian blood donors is high. There is no significant difference in the renal function status of blood donors with SCT and normal haemoglobin genotype.

Pattern and Predictors of Cardiovascular Risks among Public Servants in a Southwestern State in Nigeria

BACKGROUND

Cardiovascular disease is a major public health problem globally. The public service workers, who are facilitators of national development, are particularly vulnerable because the nature of their job predisposes them to unhealthy lifestyles. However, there is paucity of reference data on the profile of cardiovascular risks among public servants in Nigeria. Therefore, this study determined the pattern and predictors of cardiovascular risk among public servants in Southwest, Nigeria.

METHODS

A total of 1,778 public servants were recruited from 47 Ministries, Departments and Agencies in Ondo State through multi-stage random sampling technique. The World Health Organization Stepwise instrument and Framingham Heart Study non-laboratory cardiovascular risk assessment tool were used to collect data. STATA version 14.2 was used for analysis and p-value of< 0.05 was taken as significant.

RESULTS

The mean age of participants was 44.2±9.1 years. They were predominantly females (64.8%). The proportions of participants with moderate and high 10-year absolute cardiovascular risks were 18.3% and 5.6%, respectively. Significant factors associated with increased cardiovascular risk were age (p=<0.001), sex (p =<0.001), education (p =<0.001), income (p =<0.001), staff category (p =<0.001) and employment grade level (p=<0.001). The significant predictors of increased cardiovascular risk on multivariate analysis were age > 50years (AOR:1.25;CI:1.19-1.32;p=<0.001) and male sex (AOR:6.62; CI:3.76-11.65;p=<0.001).

CONCLUSION

The prevalence of increased 10-year absolute cardiovascular risk among public servants in Ondo State was high. The significant predictors were age >50 years and male sex. Cardiovascular risk reduction strategies should be encouraged among public servants especially the older males.

Spatial Distribution of COVID-19 in Nigeria

BACKGROUND

The first reported case of the novel coronavirus (COVID 19) in Nigeria was on the 27th of February 2020. Since then, the country has witnessed a steady increase in the number of patients confirmed with the disease. As of April 27th 2021, a total of 164,756 confirmed COVID-19 cases were notified making it the fifth-highest number of cases in the African region. This study aims to determine the spatial distribution of COVID-19 in Nigeria, identify clusters and determine factors associated with COVID-19.

METHODS

The study used secondary data of COVID-19 cases notified in each of the 36 states and the Federal Capital Territory between 27th February and 9th June, 2020. The Global and Local Moran'sItest were used to identify significant spatial clusters. The negative binomial regression model was used to identify factors associated with COVID-19 and p d" 0.05 was regarded as statistically significant.

RESULTS

The Local Moran I identified Lagos State as the significant cluster for COVID-19 in Nigeria at p<0.05. Higher GDP per capita and lower literacy rates were significantly associated with COVID-19 cases reported by the states while population density, BCG coverage and average temperature were not significantly associated.

CONCLUSION

The study identified Lagos State as the hotspot for the COVID-19 pandemic in Nigeria. The states with lower literacy rate and higher GDP per capita reported a higher number of COVID-19 cases. Proactive measures are needed to control of the infection in Lagos state while improving the literacy about the disease transmission and control measures.

Perceptions of the COVID-19 vaccine and willingness to receive vaccination among health workers in Nigeria

OBJECTIVE

The study aimed to examine health workers' perceptions of the coronavirus disease 2019 (COVID-19) vaccine in Nigeria and their willingness to receive the vaccine when it becomes available.

METHODS

This multi-center cross-sectional study used non-probability convenience sampling to enroll 1,470 hospital workers aged 18 and above from 4 specialized hospitals. A structured and validated self-administered questionnaire was used for data collection. Data entry and analysis were conducted using IBM SPSS ver. 22.0.

RESULTS

The mean age of respondents was 40±6 years. Only 53.5% of the health workers had positive perceptions of the COVID-19 vaccine, and only slightly more than half (55.5%) were willing to receive vaccination. Predictors of willingness to receive the COVID-19 vaccine included having a positive perception of the vaccine (adjusted odds ratio [AOR], 4.55; 95% confidence interval [CI], 3.50-5.69), perceiving a risk of contracting COVID-19 (AOR, 1.50; 95% CI, 1.25-3.98), having received tertiary education (AOR, 3.50; 95% CI, 1.40-6.86), and being a clinical health worker (AOR, 1.25; 95% CI, 1.01-1.68).

CONCLUSION

Perceptions of the COVID-19 vaccine and willingness to receive the vaccine were sub-optimal among this group. Educational interventions to improve health workers' perceptions and attitudes toward the COVID-19 vaccine are needed.

Self-perceived Burden on Caregivers, Anxiety and Depression among Chronic Kidney Disease Patients in Southern Nigeria

INTRODUCTION

Psychosocial problems are common in chronic kidney disease (CKD) patients and are associated with poor overall outcomes; however, their evaluation has not received the deserved attention. This study assessed self-perceived burden on caregivers, psychosocial wellbeing, anxiety and depression among CKD patients, and the impact on their quality of life (QoL) in two hospitals in Nigeria.

METHODS

This was a cross-sectional study. Self-perceived burden on caregivers, QoL, anxiety, and depression of the patients, were assessed using the Cousineau questionnaire, modified SF-12 questionnaire, Hospital Anxiety and Depression Scale, respectively.

RESULTS

There were 141 participants in the study comprising 50 haemodialysis (HD) patients, 41 pre-dialysis CKD patients and 50 controls. The male: female ratio for CKD patients and controls were 1.1 and 1.4 respectively. Prevalence of depressive and anxiety symptoms in the CKD patients were 46.2% and 33.0% respectively. The QoL score was significantly higher in the control group compared to the CKD patients (p= <0.001) and significantly lower in the HD patients compared to the pre-dialysis CKD patients (p= <0.001). Self-perceived burden score was significantly higher in the HD group compared to the pre-dialysis CKD group (p = < 0.001) There was a negative correlation between QoL score and self-perceived burden, hospital anxiety score and hospital depression score (p =<0.001).

CONCLUSION

Psychological disorders and self-perceived burdens are highly prevalent among CKD patients. They have negative impact on their QoL, hence regular evaluation and management of these disorders should be incorporated into the care of CKD patients.

Level of implementation of WHO COVID-19 document on rights, roles and responsibilities of health care workers in a tertiary hospital in Southwest Nigeria

Introduction

in order to curb the increasing spread of COVID-19 amongst health care workers (HCWs), the World Health Organization (WHO) released the COVID-19 Rights, Roles and Responsibilities of Health workers (COVID-19 RRRHW) policy document aimed at protecting HCWs amidst the on-going pandemic. This study determined the level of implementation of the document in a tertiary hospital in Southwest Nigeria.

Methods

this was a cross-sectional descriptive study among HCWs in a tertiary hospital in South-western Nigeria that assessed the level of implementation of the WHO COVID-19 RRRHW document using a closed ended structured questionnaire.

Results

five hundred and thirty-five HCWs participated in the study comprising 165(30.8%) males and 370(69.2%) females. Majority (87.3%) of the HCWs were 40 years and below. One hundred and sixty-three (30.5%) of the HCWs had been involved in the care of COVID-19 patients; less than 60% of the respondents were aware of the presence of an official platform for dissemination of information on suspected or confirmed cases of COVID-19 and 435(81.3%) were aware of hospital training on Infection Prevention and Control (IPC); 191(35.7%) have had uninterrupted supplies of personal protective equipment(PPE) and IPC materials; 211(39.4%) were aware of mental and counselling services in the hospital while only 106(19.8%) knew how to access these services; 289(54%) have attended IPC training and 307(57.4%) are able to don and doff PPE.

Conclusion

this study showed inadequate implementation of the WHO COVID-19 RRRHW document. There is urgent need for all stakeholders to familiarize with the document in order to ensure adequate protection of HCWs and minimize their risk of contracting COVID-19.

Prospects of telemedicine during and post COVID-19: highlighting the environmental health implications

The outbreak of the coronavirus disease 2019 (COVID-19) in late 2019 had severe implications on the normal course of events across the globe. The imposition of lockdown, quarantine, and isolation measures by most countries to curtail the spread of the coronavirus led to the rapid development of information, communication, and technological (ICT) solutions to minimize the effect of the lockdown, and as an alternative to normal day-to-day physical interactions. Telemedicine involves the delivery of health care services by qualified health professionals using ICT for the exchange of valid information where distance is a critical factor, thus enhancing access to health care services. The use of ICT as a tool to improve access to health care services and for tackling the raging pandemic was one of the options embraced and considered by many countries. Indeed, there are indications that the use of telemedicine as a complementary option to current traditional medical practice will continue in the post-COVID period. The shift to telemedicine has severe health and environmental health implications and should be done with caution. Poor management of generated electronic waste was found to be responsible for environmental pollution and health hazards affecting major organs of the human body. Countries, especially those in the developing world, lack infrastructure for effective implementation of policies required to appropriately manage electronic waste. Therefore, it is highly imperative that adequate measures are put in place to mitigate the potential hazardous effects of the shift to telemedicine.

Awareness and Knowledge of Patients' Bill of Right among Physicians and Patients in a Tertiary Hospital in Southwest Nigeria

BACKGROUND

Patients' Bill of Right (PBoR) was launched in Nigeria in 2018 with the aim of improving health service delivery to Nigerians. However, knowledge of PBoR among physicians and patients is pivotal to achieving its laudable objective.

AIM

This study assessed the awareness and knowledge of PBoR and associated factors among physicians and their patients at the University of Medical Sciences Teaching Hospital in Ondo State, Southwest Nigeria.

METHODS

This was a cross-sectional study that assessed awareness and knowledge of PBoR among physicians and patients using questionnaire. Maximum score obtainable was 16 and those with less than 8 were considered as having poor knowledge, 8-12 as good knowledge and 13-16 as excellent knowledge. P value of <0.05 was taken as significant.

RESULTS

Four hundred and fifty-three respondents made up 199 physicians and 254 patients participated in the study. There were 227(50.1%) males and 226(49.9%) females. Amongst the participants, 212(46.8%) were aware of existence of PBoR and 108(23.8%) claimed to be aware of its contents. Physicians and patients with good to excellent knowledge were 60.6% and 21.3 % respectively. The physicians had significantly better knowledge of PBoR compared to patients (p= <0.001). Factors associated with good to excellent knowledge of PBoR were male gender (p= 0.004), higher educational level (p= <0.001), being physician (p= <0.001) and younger age (p= <0.001).

CONCLUSION

Overall level of knowledge of PBoR was unsatisfactory especially among the patients. There is an urgent need for government to adequately educate and sensitize the public on PBoR in order to ensure qualitative health services delivery.

Metabolic Syndrome and Atherosclerotic Cardiovascular Risk in a Population Of Market Women in a Semi-Urban Town, South-West Nigeria

BACKGROUND

Metabolic Syndrome (MS) is a non-communicable disease of global significance. The presence of MS denotes increased risk of cardiovascular disease. The global prevalence of MS is on the increase because of lifestyle changes like consumption of high calorie, low fibre foods coupled with reduced physical activity OBJECTIVES: To determine the prevalence of MS and its components and to estimate atherosclerotic cardiovascular disease (ASCVD) risk in a population of market women.

METHODS

A cross-sectional, observational study among female traders in a market in South-western Nigeria. MS was determined using the harmonized NCEP-ATPIII and IDF criteria. The ASCVD risk estimator by the American College of Cardiologists and American Heart Association was used to assess ASCVD risk.

RESULTS

One hundred and sixty-nine female traders aged 23 to 80 years with a mean age of 52.8±13.2 years were involved in the study. Overweight and obesity were seen in 61 (36.5%) and 57 (34.1%) participants respectively. Prevalence of MS was 34.9% and the most frequent components of MS were hypertension (62.1%), low HDL-cholesterol (53.8%) and elevated serum triglycerides (18.3%). MS was associated with increasing age (p= 0.010) and BMI (p= 0.009). Significant 10-year ASCVD risk was found in 63 (52.1%) out of 121 participants eligible for ASCVD risk estimation. Significant 10-year ASCVD risk was found in 33(67%) out of 59 participants with MS.

CONCLUSION

This study demonstrated significant risk for cardiovascular disease in a population of market women. A more active lifestyle, appropriate diet and treatment of hypertension, diabetes and dyslipidaemia should be encouraged.

Coronavirus infection and kidney disease: a review of current and emerging evidence

In November 2009, an outbreak of a new strain of coronavirus (later named severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) was first noticed in the city of Wuhan in China, rapidly spreading to assume pandemic proportions within a short period of time. The disease was subsequently designated as coronavirus disease-19 (COVID-19). The death toll has continued to rise with grave health and socio-economic implications for individuals, families and nations globally. Although the respiratory tract is primarily involved in this disease, kidney affectation is increasingly reported and has been shown to worsen the prognosis of the disease. Current evidence shows that kidney disease is not uncommon in patients with coronavirus infection especially in those with COVID-19 and may arise from a constellation of factors such as hypotension, sepsis, rhabdomyolysis, multi-organ failure, use of nephrotoxic medications as well as direct infection in some cases. Factors associated with acute kidney injury in coronavirus infected patients may include elderly age, male sex, presence of co-morbidities as well as pre-existing chronic kidney disease and end stage renal disease. Although, there is presently no effective treatment for COVID-19, there is room for conservative management, extracorporeal therapy and renal replacement therapy. The aim of this review was to integrate current and emerging evidences on renal disease resulting from COVID-19 and the previous epidemics of coronavirus infections including the Middle East Respiratory Syndrome (MERS) and the Severe Acute Respiratory Syndrome (SARS) caused by other strains of the virus.

Pregnancy-related acute kidney injury: Etiologies and short-term outcomes in a tertiary hospital in Southwest Nigeria

Although the incidence of pregnancy-related acute kidney injury (PRAKI) is declining in developing countries, it still remains a major cause of maternal and fetal morbidity and mortality. The aim of this study was to determine the etiologies, short-term outcomes, and their predictors in patients with PRAKI managed in a tertiary health facility in Southwest Nigeria over a four-year period. This was a four-year retrospective review of clinical records of patients managed for PRAKI in University of Medical Sciences Teaching Hospital, Ondo State, Nigeria. Thirty-two women with a mean age of 31.09 ± 7.50 years had PRAKI during the period reviewed. Twenty-four (75%) patients were multiparous and PRAKI was most common in the postpartum period (56.3%). Twenty-three patients (71.9%) were in RIFLE Stage 3, 24 (75%) received blood transfusion, 5 (15.6%) required intensive care unit (ICU) care, 24 (75%) needed dialysis while 19 (59.4%) had hemodialysis. The common causes of PRAKI were obstetric hemorrhage in 16 (50%), sepsis in seven (21.9%), and eclampsia in six (18.8%). Maternal and fetal mortality were 34.4% and 50% respectively. Seventeen (53.1%) had full renal recovery and only one (3.1%) became dialysis dependent. Significant factors that were associated with maternal mortality were admission to ICU (P = 0.01), hypotension (P = 0.02), and impaired consciousness (P <0.001) PRAKI is still relatively common and significantly contributes to maternal and perinatal mortality in Nigeria. Obstetric hemorrhage which is the most common cause of PRAKI is preventable and treatable. There is a need for physicians to effectively prevent and manage obstetric hemorrhage.

Awareness and Practice of Vaccination of Chronic Hemodialysis Patients by Specialist Nephrology Practitioners in Nigeria: A Cross-Sectional Survey

Vaccination of hemodialysis (HD) patients reduces mortality and infection transmission in dialysis units, but its practice is perceivably poor in Nigeria with no study quantifying the level of awareness and practice to date. A questionnaire-based, cross-sectional study on nephrologists was designed. Average group performance scores were calculated for each professional group. Data were analyzed using Statistical Package for the Social Sciences version 20.0 software. The mean age of a total of 142 respondents was 40.7 ± 8.4 years. The average group performance scores for consultants, senior registrars, medical officers, dialysis nurses, and general nurses were 63.4, 63.4, 50.3, 43.4, and 43.4, respectively. Six facilities (11.1%) had active vaccination protocol against hepatitis B virus infection (HBV) alone. These comprised 4/8 (50%) private facilities and 2/46 (4.3%) public hospitals. One public tertiary hospital (2.2%) had an active vaccination protocol against Streptococcus pneumoniae. Awareness and practice of vaccination of HD patients by nephrologists is low. Practice of vaccination of HD patients is better in the private sector.

Impact of COVID-19 pandemic on renal care services in Nigeria

The COVID-19 pandemic has altered the course of events globally. Enforcement of lock down orders to curtail the spread of the pandemic had untoward consequences on the economy and health of the citizenry. In Nigeria, access to renal care was reduced by restriction of movement; inability to afford care due to economic downturn; suspension of transplant programs; uncertainties about dialysis guidelines; anxiety and reduced motivation of health care workers (HCWs) due to lack of government's commitment to their welfare and increasing rate of COVID-19 infection among HCWs. Formulation and implementation of policies to improve HCWs welfare and ease the burden of CKD patients should be prioritized in order to ensure optimal care of renal patients during the present pandemic.

Views of students on qualities expected of their lecturers: a case study of the University of Medical Sciences, Ondo city, Nigeria

Although the assessment of teachers by students has been introduced into tertiary educational development in Nigeria, very limited information exists on students’ expectations of their teachers. We investigated this component among a cohort of newly admitted students at the University of Medical Sciences in Ondo State, South-West Nigeria. This was a descriptive quantitative study consisting of a community-interactive session with students at the 100 and 200 levels of the University. Three hundred (300) students participated in the session. We first explained the purpose of the study. Thereafter, the students individually completed a semi-structured questionnaire that elicited information on their views on the qualities they expected of their lecturers. The results were analyzed quantitatively with SPSS version 21. Of the 300 students, 204 (64.0%) completed the questionnaire. Friendliness and congeniality (46.1%), good classroom management (38.7%), good sense of humor (36.3%), good communication skills (33.3%) and expertise (32.8%) were the five most desirable qualities of good lecturers listed by the students. By contrast, the five qualities which rated lowest in the assessment were equity (4.4%), mentoring capacity (4.9%), enthusiasm (6.9%), encouraging students to succeed (7.8%) and approachability (8.3%). We conclude that students at the University of Medical Sciences look out for personal social relationships with their teachers during curricular delivery. We recommend that approaches to address these concerns should be incorporated into the design of training programs for teachers and in protocols for students’ evaluation of teachers in this university and others in similar circumstances.

Level of implementation of WHO COVID-19 document on rights, roles and responsibilities of health workers in a tertiary hospital in Southwest Nigeria

Introduction

in order to curb the increasing spread of COVID-19 amongst health care workers (HCWs), the World Health Organization (WHO) released the COVID-19 Rights, Roles and Responsibilities of Health workers (COVID-19 RRRHW) policy document aimed at protecting HCWs amidst the on-going pandemic. This study determined the level of implementation of the document in a tertiary hospital in Southwest Nigeria.

Methods

this was a cross-sectional descriptive study among HCWs in a tertiary hospital in South-western Nigeria that assessed the level of implementation of the WHO COVID-19 RRRHW document using a closed ended structured questionnaire.

Results

five hundred and thirty-five HCWs participated in the study comprising 165(30.8%) males and 370(69.2%) females. Majority (87.3%) of the HCWs were 40 years and below. One hundred and sixty-three (30.5%) of the HCWs had been involved in the care of COVID-19 patients; less than 60% of the respondents were aware of the presence of an official platform for dissemination of information on suspected or confirmed cases of COVID-19 and 435(81.3%) were aware of hospital training on Infection Prevention and Control (IPC); 191(35.7%) have had uninterrupted supplies of personal protective equipment(PPE) and IPC materials; 211(39.4%) were aware of mental and counselling services in the hospital while only 106(19.8%) knew how to access these services; 289(54%) have attended IPC training and 307(57.4%) are able to don and doff PPE.

Conclusion

this study showed inadequate implementation of the WHO COVID-19 RRRHW document. There is urgent need for all stakeholders to familiarize with the document in order to ensure adequate protection of HCWs and minimize their risk of contracting COVID-19.

Legal perspectives on liabilty for medical negligence and malpractices in Nigeria

Medical practice usually involves different activities which if not professionally handled, may give rise to liabilities on the part of the medical practitioner. These liabilities may arise in tortious claims and in some other cases, may go beyond the realm of civil liabilities to criminal liabilities. This review focuses on liabilities that amount to negligence both under the civil and criminal laws in Nigeria, other instances of malpractices which may not amount to negligence but may suffice to give rise to a successful cause of action in other branches of substantive law including claims for breach of fundamental human rights; contract; and fiduciary relationship. The review concludes by emphasizing the need for caution and the need to ensure that justice is seen to be done not only to the victims but also to the medical practitioners who deserve all legal protection in the exercise of their professional duties.

Assessment of knowledge of chronic kidney disease among non-nephrology nurses in Akure, South-West Nigeria

Health workers require adequate knowledge of chronic kidney disease (CKD) to be able to play their role in reducing the burden of CKD. Most previous studies focused on assessing knowledge of doctors on CKD; however, nurses are also important in primary, secondary, and tertiary prevention of CKD. This study assessed the knowledge of non-nephrology nurses on CKD with the aim of identifying areas of knowledge gaps which will be targets for future educational programs. This was a cross-sectional descriptive study carried out among nurses in Akure, Southwest Nigeria during their mandatory continuing professional development program required for practicing license renewal. Knowledge of CKD was assessed using self-administered pretested questionnaires. P <0.05 was taken as significant. One-hundred nurses participated in the study with a male:female ratio of 1:3.7. The mean duration of their nursing experience was 14.5 ± 9.1 years. Only 15% had nephrology posting during their training. Six (6%) of the respondents had good knowledge of CKD, 55 (55%) had fair knowledge, and 37 (37%) had poor knowledge. Only 5% was aware of renal care policy in Nigeria. Junior and intermediate cadre nurses had better knowledge of CKD than senior cadre nurses (P = 0.004). Nurses who had nephrology posting during their training had significantly higher mean knowledge score than others (14.38 ± 2.25 vs. 12.93 ± 3.10, P = 0.036). There were significant deficiencies in the knowledge of CKD among non-nephrology nurses who participated in the study. Junior and intermediate cadre nurses and those who had nephrology postings had better knowledge of CKD.

The birth experience and subsequent maternal caregiving attitudes and behavior: a birth cohort study

Optimal maternal caregiving is critical for children's healthy development, yet quality of maternal caregiving may be influenced by a negative birth experience. We examined whether the birth experience was associated with maternal caregiving attitudes and behavior throughout the first year. We conducted secondary analysis of the Avon Longitudinal Study of Parents and Children birth cohort on perinatal data. The birth experience was assessed using self-report data on level of support in labor. Maternal caregiving variables were self-report maternal attitudes at one and eight postnatal months, and observed maternal behavior at 12 postnatal months. Data were analyzed using multivariable logistic regression models adjusting for critical covariates at one (N = 4389), eight (N = 4580), and 12 (N = 842) postnatal months. Feeling supported in labor was associated with a report of "immediately falling in love" with one's baby after birth, surveyed at 1 month (adjusted OR 1.41 [95% CI 1.20-1.65]), and with more positive parenting scores at 8 months (adjusted OR 1.56 [95% CI 1.36-1.79]), but not with more positive observed maternal behavior at 12 months. Additional risk factors were identified. Our findings suggest that we may be able to modify the risk of poor postnatal maternal caregiving by supporting women in labor and facilitating a positive birth experience.

A Multicentre Study of Awareness and Practice of Vaccination Against Infectious Diseases Among Haemo-Dialysis Subjects in Nigeria

BACKGROUND

Numerous studies indicate that immunization against vaccine-preventable infectious diseases lowers mortality among Chronic Kidney Disease/dialysis patients and improve their quality of life. However, their knowledge and practice of this appears to be poor in Nigeria and parts of Africa.

OBJECTIVES

We set out to determine subjects' awareness of vaccination against preventable infectious diseases and its impact on their participation in vaccination programs.

METHODS

A prospective, cross-sectional study. Data was collated using questionnaires, laboratory results and dialysis entries and analyzed using IBM SPSS Statistics19.

RESULTS

One hundred and twenty-four participants (mean age, 48.26±14.45 years) undergoing maintenance haemodialysis were studied. Sixty-two subjects (50.4%), 15.3% and 16.9% had heard of Hepatitis B Virus, S. pneumoniae and H. influenza virus respectively. Thirty-four (54.6%) of the participants first heard of these infections from sources other than healthcare personnel. Of the three common infections, study participants only received formal counselling on Hepatitis B Virus (HBV) infection. Majority had never heard of S. pneumoniae or H. influenzae. Seven (5.7%) had completed their HBV immunisation schedule only. Better educated participants were more aware of necessary vaccination against Hepatitis B Virus (p=0.000) S. pneumoniae (p=0.005) and H. influenza virus (p = 0.003). A significantly higher proportion of participants who received health-personnel driven formal education commenced vaccination against Hepatitis B virus (p=0.000).

CONCLUSION

Awareness and practice of vaccination against infectious diseases by haemodialysis patients was found to be poor. Defective system and practice of information dissemination by healthcare workers was remarkably contributory.

Prevalence of chronic kidney disease and its risk factors among adults in a semi-urban community of South-East Nigeria

BACKGROUND

Chronic kidney disease (CKD) is an increasingly prevalent problem worldwide. Treatment of end-stage kidney disease is beyond the reach of an average Nigerian. The prevention and early detection are imperative to reducing its burden.

AIM

The aim of this study was to determine the prevalence of CKD and some of its risk factors among adults in a representative semi-urban Nigerian population.

SUBJECTS AND METHODS

A cross-sectional study involving 400 randomly selected adults. Participants were assessed using the WHO stepwise approach. Urinary protein-creatinine ratio (PCR) and estimated glomerular filtration rate (GFR) from serum creatinine, among other parameters, were analysed. A PCR ≥200 mg/g was regarded as significant proteinuria while GFR <60 ml/min/1.73 m2 was regarded as reduced GFR. Participants with abnormal PCR and/or reduced GFR were re-evaluated after 3 months to document persistence of these abnormalities. CKD was defined as persistent significant proteinuria and/or reduced GFR for more than 3 months.

RESULTS

Data were complete for 328 participants. Persistent significant proteinuria was found in 5.8% while persistently reduced GFR was obtained in 4.6% of participants. Overall, the prevalence of CKD was 7.8%. The prevalence of some established CKD risk factors was old age, 36.3%; hypertension, 36.9%; diabetes mellitus, 7.9%; and family history of kidney disease, 6.4%. The predictors of CKD included old age (adjusted odds ratio = 3.2; confidence interval: 1.10-8.92; P= 0.02), hypertension: 3.5 (1.93-11.90; P= 0.001), family history of kidney disease; 4.5 (3.91-10.23; P= 0.01), generalised obesity 1.3 (1.20-6.21; P= 0.001) and central obesity 3.8 (1.13-12.68; P= 0.003).

CONCLUSION

The prevalence of CKD and some of its risk factors were high. Effective control of the modifiable risk factors identified will assist in reducing the burden of CKD.

Study of association between sickle cell trait and renal dysfunction among young adults in South-west Nigeria

Background

Although sickle cell disease has become a recognized etiology of chronic kidney disease (CKD), the sickle cell trait (SCT) variant was until recently believed to be a benign carrier state with little or no effect on the health of affected individuals. However, recent studies now appear to suggest an association between SCT and CKD.

Objective

The objective of the study is to determine the association between SCT (hemoglobin AS) and renal dysfunction among young Nigerian adults.

Methodology

This was a cross-sectional, descriptive study among apparently healthy undergraduates of Adeyemi College of Education, Ondo, southwest Nigeria. Their hemoglobin genotypes were determined using standard alkaline electrophoresis; their blood pressure, anthropometry, serum total cholesterol (TC), creatinine, and estimated glomerular filtration rate (eGFR) were determined. Data analyzed using Statistical Package for Social Sciences (SPSS) 20 were significant at P < 0.05.

Results

Six hundred and two subjects with HbAS (SCT, n = 465) and HbAA (non-SCT, n = 137) were studied. Their age range was 18-30 years with male-to-female ratio 1:3.8. There was no difference in the prevalence of renal dysfunction between SCT and non-SCT subjects (5.1% vs. 5.2%, P = 0.591). There was no increased risk of CKD among subjects with SCT (PR, 0.99 at 95% CI [0.417-2.348]).

Conclusion

SCT was not associated with increased risk of renal dysfunction among young adults in Nigeria. Further studies are needed to clarify the controversy, especially in Nigeria, with a relatively higher prevalence of SCT.

Co-existing autosomal dominant polycystic kidney disease and nephrotic syndrome in a Nigerian patient with lupus nephritis

A little over 30 cases on co-existing nephrotic syndrome and autosomal dominant polycystic kidney disease (ADPKD) have been reported from different regions of the world since 1957. We present a case report on co-existence of nephrotic syndrome (secondary to lupus nephritis) with ADPKD in a 24-year-old woman from Nigeria. She was positive for anti-double stranded DNA. Renal histology showed International Society of Nephrology/Renal Pathology Society Class II lupus nephritis. The co-existence of nephrotic syndrome and ADPKD may have been overlooked in Africa in the past. There is a need to screen for nephrotic syndrome in patients with ADPKD among clinicians in the African setting.

Evaluation of administration of discharge against medical advice: Ethico-legal considerations

BACKGROUND

Discharge against medical advice (DAMA) portends serious ethico-legal consequences for healthcare givers. Several studies have described its prevalence and pattern but hardly any to evaluate adherence to standards by medical staff while administering DAMA in developing countries.

OBJECTIVES

The objective of this study is to evaluate adherence of medical staff to standard protocols during the administration of DAMA in a public secondary hospital in Ondo State.

METHODOLOGY

In a descriptive, retrospective study we examined case files and DAMA forms of in-patients who obtained DAMA between April 2014 and September 2015 for design, signatories and completeness. Data were analysed by means of SPSS version 17.

RESULTS

A total of 235 patients (male:female, 1.03:1) who obtained DAMA out of 7465 in-patients were studied. Their mean age was 40.5 ± 19.3 years (range, 17-110 years). The overall hospital DAMA prevalence was 3.2%. DAMA forms were inadequately designed, deficient and not protective against litigation. Improper processing of DAMA was high (66.7%). The only signatories in the DAMA forms were the nurses (8.5%) and patients' relatives (100%). There was no physician entry in the forms.

CONCLUSIONS

Adherence to standard DAMA protocol by medical staff was poor. Update courses on ethico-legal matters, adopting a discharge planning team, upgrading of DAMA forms and stressing global best practices will reduce or eliminate risk of litigations.

HIV-TB co-infection in children: associated factors and access to HIV services in Lagos, Nigeria

BACKGROUND

Human immunodeficiency virus (HIV) and tuberculosis (TB) are the leading causes of death from infectious disease worldwide. The World Health Organization estimates that the prevalence of HIV among children with TB in moderate to high prevalence countries ranges between 10% and 60%. This study aimed to determine the access to HIV services of HIV-TB co-infected children.

METHODS

A retrospective review of data of children diagnosed with TB in Lagos State, Nigeria from 1 January 2012 to 31 December 2013.

RESULTS

A total of 1199 children aged between 0 and 14 years were diagnosed with TB. Of 1095 (91.3%) who underwent testing for HIV, 320 (29.2%) were HIV seropositive. The male-to-female ratio of HIV-TB positive outcomes was 1:0.9. Of the 320 HIV-TB co-infected children, 57 (17.8%) were aged <1 year, 86 (26.9%) 1-4 years and 186 (58.1%) 5-14 years; 186/320 (58.1%) began cotrimoxazole preventive therapy (CPT), and 151 (47.2%) were put on antiretroviral treatment (ART). ART uptake was not significantly higher in facilities where HIV-TB services were co-located (P > 0.05).

CONCLUSION

The uptake of CPT and ART was low. There is a need to intensify efforts to improve access to HIV services in Lagos State, Nigeria.

Awareness level of kidney functions and diseases among adults in a Nigerian population

The prevalence of kidney diseases is on the increase in Nigeria. The cost of its management is far beyond the reach of an average patient. Prevention is thus of paramount importance and awareness of kidney diseases will help in its prevention. The aim of this study is to assess the level of awareness of kidney functions and diseases among adults in a Nigerian population. A semi-structured, researcher - administered questionnaire was the tool for data collection. Four hundred and thirty-five questionnaires were analyzed. There were 160 males (36.8%) and 275 females (63.2%). The mean age was 42.8 ± 14 years with a range of 18-78 years. Among these, 82.1% were aware of the kidneys' involvement in waste removal from the body through urine while 36% and 29% were aware of kidneys' role in blood pressure regulation and blood production, respectively. Only 26.6% correctly identified at least two basic functions of the kidneys. Also, 32.6% of the respondents were aware of at least three common causes of kidney diseases in our environment. Majority of the respondents (70.7%) did not know that kidney diseases could be inherited. Furthermore, belief in alternative therapy for kidney disease was documented in 83.2%, while unawareness of dialysis as a treatment modality was recorded in 68% of the respondents. The awareness of kidney functions and diseases among the population is poor. Measures are needed to improve this to stem the rising prevalence of chronic kidney disease in Nigeria.

Suicide attempt by hanging in preadolescent children: a case series

BACKGROUND

Suicide is now among the five top causes of death in youth worldwide. However, during the preadolescent period, suicidal behaviour is rare and difficult to define because the cognitive level of young children limits their ability to plan and understand the consequences or the finality of suicide. There is virtually no information about preadolescent suicidal behaviour in Nigeria.

OBJECTIVE

To illustrate the presentation and psychosocial issues associated with preadolescent suicidal attempt using the 'hanging' method in Nigeria.

METHODS

Three case scenarios of suicide attempt by hanging in preadolescents seen at the University College Hospital, Ibadan between 2005 and 2006 were interviewed in detail along with mental state and physical examination. Family and individual therapies were embarked upon.

RESULTS

Types of psychopathology found in the preadolescents include depressive symptoms, conduct and oppositional defiant disorder and impulse control problems. Stressful life events such as family disruption, physical abuse, and bullying at school were factors associated with suicidal behaviour. The influence of the media in providing information about 'hanging' as a method of suicide was evident. Therapy yield varying results.

CONCLUSION

High risk parameters for suicide in children should be known to all health professionals. The importance of intervention strategies particularly media education, monitoring systems and further research on suicidal behaviour in this environment is apparent.
