Association of Urinary Mycotoxins with Sperm Quality: A Case-Control Study in Southern Nigeria.

The objective of this study was to determine the association between mycotoxins and the quality of spermatozoa in Nigeria. We designed a prospective case-control study involving 136 men diagnosed with reduced sperm count and quality in five infertility clinics in southwest Nigeria and 154 normal fertile controls. Sperm analysis was conducted in accordance with the recommendations of the World Health OrganizationWHO, while Liquid Chromatography-Mass Spectrometry was used to assay three metabolites of mycotoxins (zearalenone, ochratoxin A, and deoxyvinelol) in the urine samples of cases and controls. The data were analysed with descriptive statistics and non-parametric linear regression. The results showed no overall significant difference in levels of these metabolites between the cases and control groups. In contrast, higher levels of zearalenone and ochratoxin A significantly decreased sperm motility in the cases. Similarly, an increase in the level of ochratoxin A decreased sperm morphology in the unadjusted model in the cases. We conclude that exposure to mycotoxins reduces the quality of spermatozoa (motility and morphology) in Nigerian men but may have no effect on sperm count. Efforts to reduce the exposure of men to mycotoxins are important interventions to improve sperm quality and reduce the prevalence of male infertility in the country.

A Comparison of the Awareness, Attitude, and Uptake of COVID-19, Hepatitis B Virus, and Yellow Fever Vaccines Between Rural and Urban Respondents in Edo State, Nigeria.

INTRODUCTION: Despite the target set by WHO, Africa still falls short when it comes to individuals' use of COVID-19 vaccines. There is a similar pattern of low vaccine usage for the hepatitis B virus (HBV) and yellow fever (YF). AIM AND OBJECTIVE: The objective of our study is to compare the awareness, attitude, and uptake of vaccine-preventable diseases (VPD), COVID-19, HBV, and YF, between a rural and an urban community in Nigeria. METHODOLOGY: The study was a descriptive cross-sectional study carried out between January 2022 and December 2022 in a rural community, Okada, and an urban community, Benin, in Edo State, Nigeria. A total of 283 rural participants and 483 urban participants were interviewed. SPSS Statistics version 26 (IBM Corp. Released 2019. IBM SPSS Statistics for Windows, Version 26.0. Armonk, NY: IBM Corp.) was used for data collection and analysis. The significant value was set at P<0.05. RESULTS: A major percentage of both populations, 98.3% urban and 90.1% rural, reported being aware of COVID-19 vaccines (indicated by P<0.001). There was a similar pattern with HBV vaccine awareness. However, awareness of YF vaccines was more common in the rural (63.3%) community than in the urban (55.0%) community. A complete dose uptake of COVID-19 vaccines was reported by 7.7% of the rural and 2.2% of the urban respondents. The major reason for the refusal of vaccine uptake was the fear of possible side effects. CONCLUSION: The study showed that vaccine uptake for COVID-19, HBV, and YF is low despite seemingly good awareness of these vaccines. The number one reason for any vaccine refusal is the possibility of experiencing side effects.

Outcome of interventions to improve the quality of intrapartum care in Nigeria's referral hospitals: a quasi-experimental research design.

BACKGROUND: Evidence indicates that Nigeria's high maternal mortality rate is attributable primarily to events that occur during the intrapartum period. This study determines the effectiveness of multifaceted interventions in improving the quality of intrapartum care in Nigeria's referral hospitals. METHODS: Data collected through an exit interview with 752 women who received intrapartum care in intervention and control hospitals were analyzed. The interventions were designed to improve the quality indicators in the WHO recommendations for positive childbirth and assessed using 12 quality indicators. Univariate, bivariate, Poisson, and logistic regression analyses were used to compare twelve quality indicators at intervention and control hospitals. RESULTS: The interventions showed a 6% increase in composite score of quality of care indicators at intervention compared with control hospitals. Five signal functions of intrapartum care assessed were significantly (< 0.001) better at intervention hospitals. Quality scores for segments of intervention periods compared to baseline were higher at intervention than in control hospitals. CONCLUSIONS: We conclude that multiple interventions that address various components of the quality of intrapartum care in Nigeria's referral hospitals have demonstrated effectiveness. The interventions improved five of ten quality indicators. We believe that this approach to developing interventions based on formative research is important, but a process of integrating the implementation activities with the normal maternal health delivery processes in the hospitals will enhance the effectiveness of this approach. TRIAL REGISTRATION: The study was registered at the Nigeria Clinical Trials Registry. Trial Registration Number NCTR No: 91,540,209 (14/04/2016) http://www.nctr.nhrec.net/ and retrospectively with the ISRCTN.

Post-myomectomy omental infarction: a case report.

BACKGROUND: Omental Infarction (OI) is uncommon and mimics common causes of acute abdomen. It is important to differentiate it from other abdominal conditions that require emergency management. It was first reported in literature in 1896 and about 400 cases have been reported till date. CASE PRESENTATION: We reported on a 41 year-old Para 0+0 Ibo house wife who presented with 10 years history of supra-pubic mass and five months history of excessive menstrual flow. After physical examination, a diagnosis of symptomatic uterine fibroid was made. She had myomectomy and the raw surface created after the excision of the myomas was covered with omentum. Wound infection developed on the 8th post-operative day leading to a wound breakdown and later partial extrusion of infarcted omental tissue through the dehisced wound. During re-exploration, the infarcted omental tissue was extracted and the residual abdominal abscess was drained. Surgical site wound infection occurred on the 3rd day after re-operation and a sub-acute intestinal obstruction developed on the 4th day thereafter which responded to conservative management. CONCLUSION: Careful surgical technique is imperative when utilizing the omentum for reconstructive abdominal surgery. Torsion of the omentum and creation of excess tension while using the omentum for reconstructive procedures should be avoided and increase awareness of this uncommon disease condition by the surgeon is also important. This case is to report a rare finding of omental infarction following myomectomy.

Outcomes of a multifaceted intervention to prevent eclampsia and eclampsia-related deaths in Nigerian referral facilities.

BACKGROUND: Eclampsia causes maternal mortality in Nigeria. This study presents the effectiveness of multifaceted interventions that addressed institutional barriers in reducing the incidence and case fatality rates associated with eclampsia. METHODS: The design was quasi-experimental and the activities implemented at intervention hospitals included a new strategic plan, retraining health providers on eclampsia management protocols, clinical reviews of delivery care and educating pregnant women and their partners. Prospective data were collected monthly on eclampsia and related indicators from study sites over 2 y. The results were analysed by univariate, bivariate and multivariable logistic regression. RESULTS: The results show a higher eclampsia rate (5.88% vs 2.45%) and a lower use of partograph and antenatal care (ANC; 17.99% vs 23.42%) in control compared with intervention hospitals, but similar case fatality rates of <1%. Overall, adjusted analysis shows a 63% decrease in the odds of eclampsia at intervention compared with control hospitals. Factors associated with eclampsia were ANC, referral for care from other facilities and older maternal age. CONCLUSION: We conclude that multifaceted interventions that address challenges associated with managing pre-eclampsia and eclampsia in health facilities can reduce eclampsia occurrence in referral facilities in Nigeria and potential eclampsia death in resource-poor African countries.

Birth preparedness and complication readiness: Evaluating the "know-do" gap among women receiving antenatal care in Benin City, Nigeria.

Across several African countries, birth preparedness and complication readiness (BPACR) among pregnant women is poor. The practice of BPACR, though improving in recent years, is not commensurate with the knowledge available to pregnant women. Maternal health indices remain sub-optimal. This study evaluates the determinants of this "know-do' gap among women receiving antenatal care at a secondary health facility in Benin City, Nigeria. A cross-sectional study involving 427 pregnant women was conducted between October and December 2020 using a structured interviewer-administered questionnaire. The prevalence of knowledge and practice were described, and the determinants of BPACR practice evaluated using bivariable (chi-square) analysis and multivariable ordinal logistic regression with post-estimation predictive margins analysis. About 77% of respondents had good birth preparedness practice. Multivariable regression revealed that respondents with poor knowledge and moderate knowledge of components of BPACR had statistically significant lower odds (OR:0.05 (95% CI: 0.02-0.13) and 0.10 (95% CI: 0.03-0.30) times, respectively) for greater practice of BPACR when compared to those with good knowledge. Respondents with poor knowledge of danger signs had statistically significant lower odds (OR: 0.08 (95% CI: 0.03-0.26) for greater practice of BPACR when compared to those with good knowledge. But predictive margins analyses demonstrates that knowledge, though critical to practice, is insufficient to optimize practice. The optimum number of danger signs women need to know to improve practice may be between eight to ten. Beyond this number, practice may not change significantly. Other predictors of BPACR practice include income level, parity, gravidity, and residential settings. The number of antenatal clinic visits had no statistically significant correlation with BPACR practice. Interventions to facilitate practice at the community level may be helpful to improve outcomes and bridge the know-do gap with respect to BPACR within the study context.

Causes and Risk Factors for Male Infertility: A Scoping Review of Published Studies.

Background: Despite the evidence of declining sperm counts worldwide and the increasing prevalence of male infertility, there has been limited documentation of the potential causes and risk factors for male infertility. With limited methods of primary treatment of male infertility, understanding the causes and risk factors will pinpoint specific lines of prevention. Objective: We reviewed published studies on causes and risk factors for male infertility and identify gaps in the literature enabling more focused research and innovations. Design/Setting: The study was a scoping review. The review included studies on the causes and risk factors of male infertility published in scientific/academic publications. It was not limited to any region or date. The following databases were searched: Cumulative Index to Nursing and Allied Health Literature, Wiley online, HINARI, Science Direct, PubMed/Medline, Google Scholar, African Journals Online, and the WHO Repository. In total, 1295 articles were identified. After removing 357 duplicates, 938 articles were screened, and 71 articles were identified for inclusion, while 60 articles met the inclusion criteria. Results: Four broad causes and risk factors of male infertility identified were 1) biological/physiological/genetic causes, 2) behavioral/lifestyle risk factors, 3) environmental factors, and 4) socio-demographic risk factors. However, no substantive results on actual causes under each category were identified, leaving gaps for further research and experimentation. Conclusion: The results indicate limited knowledge of the actual causes of male infertility in published studies. The gaps in knowledge that need to be bridged to enable a fuller understanding of the actual causes of male infertility were highlighted.

The magnitude and determinants of depressive symptoms amongst women in early pregnancy in Southern Nigeria: A cross-sectional study.

Background: Antenatal depression (AD) is prevalent and associated with adverse pregnancy, maternal and child outcomes, yet no study has addressed its magnitude and predictors in early pregnancy in Nigeria. Aim: To determine the prevalence and factors associated with AD in first half of pregnancy. Setting: Multicentric health facilities in Southern Nigeria. Methods: A multicentric health-facilities-based cross-sectional study was conducted from January to July 2018. Using pretested structure interviewer-administered questionnaires, antenatal depressive symptoms were assessed amongst 511 pregnant mothers with the Edinburg Postnatal Depressive Scale tool. Socio-demographic, socio-economic, clinical, family and social factors were also measured. Descriptive statistics, bivariate and multivariable logistic regression analyses were employed to describe and identify factors associated with AD. Results: The prevalence of antenatal depressive symptoms in early pregnancy in this study was 29.4% (95% confidence interval [CI] 26.6-32.9). Factors independently associated with AD were intimate partner violence (adjusted odds ratios [AOR] = 8.10, 95% CI 5.00-13.14), marital dissatisfaction (AOR 5.48, 95% CI 3.48-8.38), poor social support (AOR 4.70; 95% CI 2.99-7.38), past history of depression (AOR 4.67; 95% CI 2.47-8.80), previous pregnancy complication (AOR 2.50, 95% CI 1.57-3.89), low socio-economic status (AOR 2.41, 95% CI 1.61-3.66) and unplanned pregnancy (AOR 2.35, 95% CI 1.47-3.64). Conclusions: The prevalence of antenatal depression is high with modifiable risk factors requiring context-specific policies such as provision of family, social and economic support for mothers at the earliest possible contact in the antenatal period.

Outcomes of a multifaceted intervention to improve maternal satisfaction with care in secondary hospitals in Nigeria.

Background: Data in Nigeria suggests a high level of dissatisfaction among women attending maternity care in health facilities due to long wait times, disrespectful care, and poor attention by healthcare personnel. Objective: To examine the effectiveness of a multifaceted intervention in improving self-reported indicators of maternal healthcare satisfaction by women who use referral facilities in two regions of Nigeria. Method: The design was quasi-experimental and consisted of two intervention facilities and two control facilities. The interventions included strategic planning, staff re-training, a computerized appointment system, health education/feedback, maternal death reviews and surveillance, and advocacy. A random sample of 2262 women was selected (1205 in the intervention sites and 1057 in the two control sites) to respond to a 24-item questionnaire on service satisfaction as they exited the health facilities. Adjusted Poisson and binary regression analyses were used to assess and compare proportions of reported satisfaction by women between the intervention and control sites. Results: Women in the intervention sites were 54% more likely than those in control sites to report overall satisfaction with services. They were significantly less likely to report inadequate security arrangements in accessing the health facilities (p < .1); and three times more likely to agree that health workers were extremely thorough and careful in attending to them (p < .1). Conclusion: The interventions had positive effects on improving women's satisfaction with care. The findings from this study have implications for the design and implementation of interventions that address women's concerns relating to the provision of care and consequently improve service utilization.

Outcome of multifaceted interventions for improving the quality of antenatal care in Nigerian referral hospitals.

BACKGROUND: The study was designed as quasi-experimental research to investigate the effectiveness of multifaceted interventions for improving the quality of antenatal care in referral hospitals in Nigeria. Two referral hospitals (the Central Hospital in Benin City, South-South Nigeria, and the General Hospital in Minna) served as intervention sites, while two hospitals in comparable locations, (the Central Hospital Warri and the Suleja Hospital Abuja) were the control hospitals. METHODS: Intervention activities consisted of the introduction of a strategic plan with the shared vision of reducing maternal mortality by 50% in 1 year in the hospitals; staff training and re-training; the establishment of an automated appointment system; composite health education involving couples and providers; advocacy with policymakers; and the implementation of maternal death reviews and surveillance. These activities were implemented in the intervention hospitals over 21 months (October 2017 to June 2019). Exit interviews of pregnant women at intervention and control sites by trained interviewers were used to assess the quality of antenatal care after their visit, A total of 777 women were interviewed (427 in the intervention sites and 350 in the control sites). Data were analyzed with univariate and multivariate Poisson and logistic regression to determine the extent to which health providers in the clinics completed the 18 signal functions identified in the WHO assessment tool. RESULTS: The regression analyses showed the interventions were effective in improving six quality indicators (QIs) for counseling and information sharing. The difference between intervention and control sites on these QIs was significant at < 0.05. On the contrary, the interventions were less effective for maternal and fetal measurements; and disease testing and management QIs. CONCLUSION: The positive effects of the interventions are likely due to the effectiveness of the training and health education components. The lack of intervention impact observed for maternal and fetal measurements may be due to the high workload of care staff and inadequate clinic supplies, which we did not address. We conclude that interventions that address the quality of antenatal care in low-resource settings should focus on improving all elements of care, including adequate staffing and mobilization of material resources. TRIAL REGISTRATION: This study was registered in the ISRCTN on August 14th, 2020. TRIAL REGISTRATION NUMBER: SRCTN17985403 . Retrospective registration. The reason for the retrospective registration is the current non-recognition of the Nigeria Clinical Trials Registry (NCTR); which is currently not an ICMJE or WHO ICTRP approved registry. (This study was registered in the Nigeria Clinical Trials Registry on April 14th, 2016. Trial Registration Number NCTR No: 91540209 ).

Maternal death review and surveillance: The case of Central Hospital, Benin City, Nigeria.

BACKGROUND: Despite the adoption of Maternal and Perinatal Death Surveillance and Response (MPDSR) by Nigeria's Federal Ministry of Health to track and rectify the causes of maternal mortality, very limited documentation exists on experiences with the method and its outcomes at institutional and policy levels. OBJECTIVE: The objective of this study was to identify through the MPDSR process, the medical causes and contributory factors of maternal mortality, and to elucidate the policy response that took place after the dissemination of the results. METHODS: The study was conducted at the Central Hospital, Benin between October 1, 2017, and May 31, 2019. We first developed a strategic plan with the objective to reduce maternal mortality by 50% in the hospital in two years. An MPDSR committee was established and the members and all staff of the Maternity Department of the hospital were trained to use the nationally approved protocol. All consecutive cases of maternal deaths in the hospital were then reviewed using the MPDSR protocol. The results were submitted to the hospital Management and its supporting agencies for administrative action to correct the identified deficiencies. RESULTS: There were 18 maternal deaths in the hospital during the period, and 4,557 deliveries giving a maternal mortality ratio (MMR) of 395/100,000 deliveries. This amounted to a seven-fold reduction in MMR in the hospital at the onset of the project. The main medical causes identified were obstetric hemorrhage (n = 10), pulmonary embolism (n = 2), ruptured uterus (n = 2), eclampsia (n = 1), anemic heart failure (n = 1) and post-partum sepsis (n = 2). Several facility-based and patient contributory factors were identified such as lack of blood in the hospital and late reporting with severe obstetric complication among others. Response to the recommendations from the committee include increased commitment of hospital managers to immediately rectify the attributable causes of deaths, the establishment of a couples health education program, mobilization and sensitization of staff to handle pregnant women with great sensitivity, promptness and care, the refurbishing of an intensive care unit, and the increased availability of blood for transfusion through the intensification of blood donation drive in the hospital. CONCLUSION: We conclude that the results of MPDSR, when acted upon by hospital managers and policymakers can lead to an improvement in quality of care and a consequent decline in maternal mortality ratio in referral hospitals.
