Essential competencies of nurses for climate change response in Saudi Arabia: A rapid literature review.
Aim: Amidst the mounting challenges posed by climate change, the healthcare sector emerges as a vital frontliner, with nurses standing as its linchpins. This review delves into the pivotal role of nurses in combatting the health consequences of climatic alterations, particularly within the nuanced environment of Saudi Arabia. Design: A rapid literature review. Method: Drawing from a rigorous analysis of 53 studies, our exploration revolves around the preparedness strategies formulated in response to Saudi Arabia's changing climate. The variables analysed included study design, sample size, focus area, geographical coverage and key findings related to nurse competencies. Data were collected using a structured data extraction form and analysed using thematic content analysis. Employing content analysis, we discerned essential domains: from grasping the health impacts of climate change to customizing care for the most susceptible populations and championing advocacy initiatives. Findings: Salient findings highlight nurses' profound understanding of both direct and secondary health implications of climate shifts. Additionally, the results emphasize the tailored interventions needed for vulnerable groups, capacity building and disaster readiness. Crucially, our findings spotlight the significance of weaving cultural, ethical and regional threads into nursing strategies. By painting a comprehensive picture, we showcase the delicate balance of environmental evolution, healthcare dynamics and the unique socio-cultural tapestry of Saudi Arabia. Conclusion: The results of our analysis revealed key competencies required for nurses, including the ability to address immediate health impacts, provide tailored care for vulnerable populations and engage in advocacy and policy formulation. In summation, nurses' multifaceted roles-from immediate medical care to research, advocacy and strategizing-underscore their invaluable contribution to confronting the health adversities sparked by climate change. Our review accentuates the essential contributions of nurses in tackling climate-related health hurdles and calls for more nuanced research, policy adjustments and proactive measures attuned to Saudi Arabia's distinct backdrop.

Association between alcohol intake, mild cognitive impairment and progression to dementia: a dose-response meta-analysis
Background Mild cognitive impairment (MCI) is a cognitive state falling between normal aging and dementia. The relation between alcohol intake and risk of MCI as well as progression to dementia in people with MCI (PDM) remained unclear. Objective To synthesize available evidence and clarify the relation between alcohol intake and risk of MCI as well as PDM. Method We searched electronic databases consisting of PubMed, EMBASE, Cochrane Library, and China Biology Medicine disc (CBM) from inception to October 1, 2019. Prospective studies reporting at least three levels of alcohol exposure were included. Categorical meta-analysis was used for quantitative synthesis of the relation between light, moderate and heavy alcohol intake with risk of MCI and PDM. Restricted cubic spline and fixed-effects dose-response models were used for dose-response analysis. Result Six cohort studies including 4244 individuals were finally included. We observed an unstable linear relation between alcohol intake (drinks/week) and risk of MCI (P linear = 0.0396). It suggested that a one-drink increment per week of alcohol intake was associated with an increased risk of 3.8% for MCI (RR, 1.038; 95% CI 1.002-1.075). Heavy alcohol intake (> 14 drinks/week) was associated with higher risk of PDM (RR = 1.76; 95% CI 1.10-2.82). And we found a nonlinear relation between alcohol intake and risk of PDM. Drinking more than 16 drinks/week (P nonlinear = 0.0038, HR = 1.42; 95% CI 1.00-2.02), or 27.5 g/day (P nonlinear = 0.0047, HR = 1.46; 95% CI 1.00-2.11) would elevate the risk of PDM. Conclusion There was a nonlinear dose-response relation between alcohol intake and risk of PDM. Excessive alcohol intake would elevate the risk of PDM.
