Heavy precipitation events over East Africa in a changing climate: results from CORDEX RCMs

The study assesses the performance of 24 model runs from five COordinated Regional climate Downscaling Experiment (CORDEX) regional climate models (RCMs) in simulating East Africa’s spatio-temporal precipitation characteristics using a set of eight descriptors: consecutive dry days (CDD), consecutive wet days (CWD), simple precipitation intensity index (SDII), mean daily annual (pr_ANN), seasonal (pr_MAM and pr_OND) precipitation, and representatives of heavy precipitation (90p) and very intense precipitation (99p) events. Relatively better performing RCM runs are then used to assess projected precipitation changes (for the period 2071–2099 relative to 1977–2005) over the study domain under the representative concentration pathway (RCP) 8.5 scenario. The performance of RCMs is found to be descriptor and scope specific. Overall, RCA4 (r1i1p1) forced by CNRM-CERFACS-CNRM-CM5 and MPI-M-MPI-ESM-LR, REMO2009 (r1i1p1) forced by MPI-M-MPI-ESM-LR, and RCA4 (r2i1p1) forced by MPI-M-MPI-ESM-LR emerge as the top four RCM runs. We show that an ensemble mean of the top four model runs outperforms an ensemble mean of 24 model simulations and ensemble means for all runs in an RCM. Our analysis of projections shows a reduction (increase) in mean daily precipitation for MAM(OND), an increase(decrease) in CDD(CWD) events, and a general increase in SDII and the width of the right tail of the precipitation distribution (99p–90p). An increase in SDII and 99p–90p implies a possibility of occurrence of heavy and extreme precipitation incidences by the end of the twenty-first century. Our findings provide important information to support the region’s climate change adaptation and mitigation efforts

Support Care Cancer

OBJECTIVE: Spiritual well-being was found to have some protective effect against end-of life despair in cancer patients. We aimed at assessing the impact of spirituality on the quality of life, depression, and anxiety of Lebanese cancer patients. METHODS: Our observational transversal monocentric study was conducted between January and April 2016 among a convenient sample of 115 Lebanese cancer patients admitted to Hotel-Dieu de France Hospital (HDF), Beirut-Lebanon. In addition to socio-demographic and clinical data, three questionnaires were used: EORTC QLQ-C30 (European Organization for Research and Treatment of Cancer Quality of Life Questionnaire, 3rd version), FACIT-Sp-12 (Functional Assessment of Chronic Illness Therapy-Spiritual Well-Being; The 12-item Spiritual Well-Being Scale, 4th version), and HADS (Hospital Anxiety and Depression Scale). Eighteen patients taking anxiolytic and/or antidepressants were not included in the analysis. The remaining 97 patients were analyzed. RESULTS: Better emotional and cognitive functioning was seen in patients with higher meaning, peace, faith, and total FACIT scores. Meaning, peace, and total FACIT scores were also higher among patients with better global health status and quality of life. Anxiety as well as depression was significantly associated to all spiritual well-being factors. CONCLUSION: Spirituality can improve quality of life and decrease the incidence of anxiety and depression in cancer patients. Our results highlight the need to incorporate spiritual care in healthcare systems
