Dengue Virus is Hyperendemic in Nigeria from 2009 to 2020: A Contemporary Systematic Review.

BACKROUND: Data on Dengue virus (DENV) infection prevalence, geographic distribution and risk factors are necessary to direct appropriate utilization of existing and emerging control strategies. This study aimed to determine the pooled prevalence, risk factors of DENV infection and the circulating serotypes within Nigeria from January 1, 2009 to December 31, 2020. MATERIALS AND METHODS: Twenty-one studies out of 2,215 available articles were eligible and included for this systematic review. Relevant articles were searched, screened and included in this study according to the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) criteria. The risk of bias in primary studies was assessed by Cochrane's method. Heterogeneity of pooled prevalence was calculated using the chi-square test on Cochrane's Q statistic, which was quantified by I-square values. The random-effects analyses of proportions were used to determine the pooled prevalence of DENV antibodies, antigen and RNA from eligible studies. RESULTS: Of these, 3 studies reported co-circulation of all the 4 serotypes, while 2 separately reported co-circulation of DENV-1 &2 and DENV-1 to -3. All the antibody-based studies had significantly high heterogeneity (I² >90%, P <0.05), while the NS1 and PCR-based studies had low heterogeneity (I² <25%, P >0.05). The pooled prevalence of DENV IgM, IgG, RNA, NS1 and neutralizing antibodies were 16.8%, 34.7%, 7.7%, 7.7% and 0.7%, respectively. South-east Nigeria had the highest pooled DENV-IgG seropositivity, 77.1%. Marital status, gender, educational level and occupation status, the proximity of residence to refuse dumpsite, frequent use of trousers and long sleeve shirts were significantly associated with DENV IgG seropositivity (P <0.05). CONCLUSION: Based on these findings, it can be inferred that Nigeria is hyperendemic for Dengue fever and needs concerted efforts to control its spread within and outside the country.

Midwives perceptions of partner presence in childbirth pain alleviation in Nigeria hospitals.

OBJECTIVE: partner presence in the labour room can influence childbirth pain outcomes and maternal well-being. We examined midwives' perception of the use of partner presence in the management of childbirth pain in Nigerian hospitals. DESIGN: a descriptive cross-sectional quantitative study. SETTING: maternity units of four hospitals in Abuja, Nigeria, Jun.-Dec., 2014. PARTICIPANTS: 100 midwives selected through convenience sampling. MEASUREMENTS: data collected using the Abuja Instrument for Midwives (AIM) questionnaire underwent frequency, correlation, and content analysis. FINDINGS: most midwives felt partner presence contributed to pain relief and were willing to allow partner presence as an intervention for childbirth pain. However, only every fourth midwife reported using partner presence as a pain management intervention. KEY CONCLUSION: partner presence is perceived as contributing to pain relief and is a non-pharmacological technique reported to be utilised by midwives for pain management during childbirth. However, Nigeria suffers from poor utilisation of partner presence as a pain management intervention during childbirth. IMPLICATION FOR PRACTICE: information from this study can improve midwifery practice and aid further research regarding midwives' attitudes, knowledge and usage of partner presence in pain management during childbirth.
