Background

The objective of this scoping review is to map out what has been published in the scientific literature on the relationship between climate change-related events and how these overlap with associated changes in resource availability, transactional sex and HIV incidence and prevalence, within fishing communities in the Lake Victoria basin. This objective is informed by the fact that climate change and the associated natural resource strains in the Lake Victoria region have exacerbated existing inequities within fishing communities. Vulnerable populations, especially women, engage in strategies such as transactional sex to cope with the uncertainty of natural resource-dependent livelihoods. This practice greatly increases women’s risk of contracting HIV in this region, with prevalence rates four to five times the national averages. This scoping review will thus show how the existing empirical literature reports on climate change, transformation in natural resources and livelihoods, and transactional sex and HIV in the Lake Victoria region.

Methods

Studies that meet the following inclusion criteria will be included: align with at least two of the major concepts of interest, including climate change, transactional sex, HIV/AIDS, Lake Victoria Basin and/or empirical studies; are published in English and after 2012; and focus on the Lake Victoria basin. The scoping review will be guided by the JBI Manual for Evidence Synthesis: Scoping Reviews, supported by the standard principles of Arksey and O’Malley. The specific search strategies to be implemented were developed with guidance from an experienced research librarian to align with the inclusion criteria. The search will be conducted in relevant global databases, with two reviewers screening the results and extracting relevant data points. Finally, results will be reported using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews flow diagram, and summarised in figures, tables and text.

Discussion

The scoping review is designed to comprehensively scope the existing literature and document the coverage of linkages between transactional sex, HIV/AIDS and sustainable livelihoods in the context of climate change with a view to informing health systems responses to human health specific to the HIV epidemic.

Scoping review registration

The proposed scoping review is registered with the Open Science Foundation (OSF), registration number:https://doi.org/10.17605/OSF.IO/9DTW4.

Retinal detachment in Nigerians: a multicentre cross-sectional study on demographics, risk factors for blindness and surgical outcomes in a developing country

Objective

To compare the presenting demographic and clinical characteristics of rhegmatogenous retinal detachment (RRD) with other RD types, investigate risk factors of blinding RD and the outcome of surgical intervention.

Design

Prospective, cross-sectional and multicentre.

Setting

Four ophthalmic centres in three geographic locations of Nigeria.

Participants

264 eyes from 237 patients diagnosed with RRD, tractional retinal detachment (TRD) and exudative retinal detachment (ERD) seen between April 2019 and March 2020.

Results

264 eyes of 237 patients were diagnosed out of 35 641 patients screened. RRD was the most common RD (n=167 (70.5%), TRD 61 (25.7%) and ERD 9 (3.8%) patients). The hospital-based prevalence of all RD is 6.6 per 1000 patients (0.66%), and for RRD alone, 4.7 per 1000 patients (0.47%). The most common symptom was a sudden decline in vision, 100 patients (42.2%); floaters and flashes were uncommon, 5 (2.1%). RRD presented earliest, with a median symptom duration of 2 months, and TRD and ERD at 7.5 months each.

The 46–65-year age group had the highest representation, RRD (n=70, 41.9%), TRD (n=41, 67.3%), ERD (n=4, 44.4%). The mean age was highest in TRD (52.3±12.7 years) and lowest in RRD (44.0±17.5 years) and ERD (45.2±20.4 years). Males dominated (RRD 70.1%, TRD 62.3%, and ERD 66.7%). Ocular trauma was highest in RRD 29.3%, TRD 7.5% and ERD 10%; fellow eye RD was highest in TRD 47.5%, ERD 20%, RRD 8% and myopia was highest in RRD 27.6%.

Two-thirds of eyes were blind (Snellen best-corrected visual acuity

Shorter symptom duration is associated with better preoperative and postoperative vision. In contrast, longer durations are connected to poorer outcomes. Eyes with symptoms lasting less than a week had a 17% rate of postoperative blindness, compared with 30% in cases lasting 1–3 months, and 51% in cases exceeding 6 months.

Conclusions

Delays in diagnosing and treating RD result in high rates of preoperative blindness, which can be reversed with surgery even after several weeks of symptoms. Understanding the associations between RD and the risk of blinding RD in developing countries will benefit early diagnosis, treatment and improve treatment outcomes.
