Pollinator-dependent crops significantly contribute to diets and reduce household nutrient deficiencies in sub-Saharan Africa

Recent literature highlights the potential of animal pollinator-dependent (PD) crops in enhancing food and nutrition security, although there is a lack of detailed household-level estimates. In this study, we investigate the nutrient composition, productivity, and contribution of PD and pollinator-independent (PI) crops to household nutrition in four sub-Saharan African (SSA) countries. We also evaluate the impact of reallocating resources from PI crops to PD crops on nutrient deficiencies, utilizing nationally representative panel data from three waves and over 30,000 household-year observations. Our findings reveal that PD crops exhibit higher micronutrient content per unit, albeit with lower macronutrient content compared to PI crops. PI crops have higher yield of calories per hectare while PD crops have higher vitamin A yield per hectare. However, protein and iron yield for PD and PI crops varies across countries. PI crops predominantly contribute to macronutrients and iron, while PD crops significantly contribute to vitamin A production. Our econometric results demonstrate that increasing the cultivation of PD crops relative to PI crops reduces the prevalence of nutrient deficiencies and increases crop income without compromising macronutrients production. This suggests that greater investment in PD crop production can be an integral approach to achieving nutrition security in SSA.

Characteristics of interprofessional rehabilitation programs for patients with chronic low back pain evaluated in the literature: a scoping review protocol

BACKGROUND

Interprofessional rehabilitation programs have demonstrated effectiveness at improving health-related quality of life, function, work abilities, and reducing pain, for patients with chronic low back pain (CLBP). However, the characteristics of interprofessional rehabilitation programs vary widely across studies. Therefore, clarifying and describing key characteristics of interprofessional rehabilitation programs for patients with CLBP will be valuable for future intervention design and implementation. This scoping review aims to identify and describe the key characteristics of interprofessional rehabilitation programs for patients with CLBP.

METHODS

Our scoping review will follow the framework developed by Arksey and O'Malley, further enhanced by Levac et al. and the Joanna Briggs Institute (JBI). Electronic databases, including MEDLINE, EMBASE, CINAHL, PsycINFO, SCOPUS, PubMed, Web of Science, and Cochrane Library, will be searched to identify relevant published studies. Our scoping review will consider all primary source peer-reviewed published articles that evaluated interprofessional rehabilitation programs for adults with CLBP from all countries and any therapeutic settings. The Covidence software will be used to remove duplicates, article screening, record the step-by-step selection process, and data extraction. The analysis will involve a descriptive numerical summary and narrative analysis. Data will be presented in graphical and tabular format based on the nature of the data.

DISCUSSION

This scoping review is expected to provide a source of evidence for developing and implementing interprofessional rehabilitation programs in new settings or contexts. As such, this review will guide future research and provide key information to health professionals, researchers and policymakers interested in designing and implementing evidence and theory-informed interprofessional rehabilitation programs for patients with CLBP.

Diet quality, food insecurity and risk of cardiovascular diseases among adults living with HIV/AIDS: a scoping review protocol

INTRODUCTION

Cardiovascular diseases (CVDs) are the single greatest contributor to global mortality. The successful introduction and scale-up of antiretroviral therapy (ART) delivered a reduction in HIV mortality. Consequently, an association was found between the scale-up of ART and an increased prevalence of comorbidities among people living with HIV (PLWH) such as hypertension and dyslipidaemia. A higher quality diet can delay the onset of comorbidities related to HIV infection. Diet quality and its methods of assessment are not fully established among PLWH. This review will identify the diet quality and food insecurity indices that have been used among PLWH and how these constructs are associated with risk of developing CVD.

METHODS AND ANALYSIS

The frameworks recommended by Arksey and O'Malley and the Joanna Briggs Institute's manual for conducting scoping reviews will be adopted. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews guidelines will be used for reporting. A search strategy was developed using keywords related to the topic. A preliminary MEDLINE (via PubMed) search was conducted on 11 November 2020 to develop a comprehensive search strategy. The final search will be conducted on PubMed, EbscoHost, Scopus, Web of Science and Cochrane Library databases. Titles and abstracts of retrieved records will be screened independently by two reviewers. Data will be extracted from records that meet the inclusion criteria using a predesigned charting tool. Discrepancies in decisions made by reviewers will be resolved by consensus or the decision of a third reviewer. Extracted data will be presented in tables or charts. A descriptive summary of the charts or tables will follow.

ETHICS AND DISSEMINATION

Ethical approval is not required for a scoping review. Findings will inform other studies currently underway and will be presented at conferences and published in peer-reviewed journals. REGISTRATION NUMBER: https://osf.io/7k3ja.
