高温环境中运动会引起体温调节和其它生理压力,继而可导致耐力运动能力的损害。本共识性声明的目的是提供最新的建议以使热环境中体育活动时的运动能力最优化。可用于降低热应激压力和优化运动能力的最重要干预方式是热习服,其应包括1~2周以上反复的运动—高温环境暴露。此外,运动员应在正常水合状态下开始比赛和训练,并将运动中的脱水最小化。随着商用降温系统（如降温背心）的发展,在高温环境中训练或比赛前,运动员可以采取降温策略来促进热的散发或提高蓄热能力。而且,赛事组织者应该设计大面积的遮阳区域,并提供降温和补水设施,按照最小化运动员的健康风险来安排赛事,尤其是在大众参与的赛事中及一年之中炎热天气开始之初。以最近的2008年奥运会和2014年国际足联世界杯为例,当比赛在高温环境中举行时,赛事主管机构应考虑在比赛中或比赛之间允许额外的（或更长的）恢复期以提供补水和降温的时机。

Introduction: Human immunodeficiency virus (HIV) is a major public health problem with high morbidity and mortality among children. The objective of this work was to audit the deaths of children and adolescents with HIV infection followed up in the pediatric d.partment of the Regional Teaching Hospital of Borgou/Alibori (CHUdB/A) the from 2005 to 2020. patients and Method: This was a retrospective and descriptive study conducted in the pediatric d.partment of CHUd/B-A in parakou. All children with HIV infection who died from January 1, 2005 to August 31, 2020 were included. data collection was carried out in three stages: a phase of medical records processing, a phase of community survey and a phase of death audits. The variables studied were sociodemographic, clinical, biological, therapeutic and evolutionary. Results: Over the study period, the data of 464 infected children were recorded, including 92 deaths, representing a case fatality rate of 19.83%. Severe acute malnutrition (69.23%), gastro-intestinal tract infections (43.58%) and serious opportunistic pulmonary infections (24.36% pulmonary tuberculosis and 19.23% pneumocystis) were the main causes of death. The main dysfunctions found were: the delayed diagnosis of HIV infection (79.35%), the absence or delay in consultation when the child’s clinical condition deteriorates (32.61% and 47.83%), delayed initiation of antiretroviral treatment (42.39%) and non-adherence to treatment (38.04%). Non-adherence to treatment was predominant in adolescents (90.49%). Conclusion: Specific interventions for early detection, adequate nutritional care, psychosocial support for adolescents and mothers of children are necessary to reduce mortality due to HIV among children and adolescents.

Introduction: Sickle cell disease is a public health problem in sub-Saharan Africa. A national referral center for the management of infants and.pregnant women with sickle cell disease (CpMI-NFEd) was created three decades ago in Cotonou, in the south of Benin with two regional branches including that of parakou in the North for better access of patients to specialized care. This work is a review of five years of activities in order to describe the epidemiological, clinical, hematological and evolutionary profiles of the children followed up in the said branch. Method: This was a descriptive and retrospective cross-sectional study on the medical records of children with sickle cell disease, followed up at the regional branch of CpMI-NFEd in Borgou/Alibori from June 1, 2017 to May 31, 2022. The variables studied were epidemiological, clinical, biological and evolutionary. Results: A total of 101 children with sickle cell disease were included in the study, including 78 homozygous SS (77.2%) and 23 heterozygous SC (22.8%). Their mean age at inclusion was 51.2 ± 37.6 months [6 - 204]. The sex ratio was 1.4. Vaso-occlusive crises were the main diagnostic circumstances in 42.3% of homozygotes. More than half of the children (51.5%) had a regular follow-up. The average baseline level of hemoglobin (Hb) in homozygous children was 8.8 ± 1.4 g/dl [5.8 - 11.5];and the rate of Hb S varied between 61.9 and 94.7%. In heterozygous SC children, the mean baseline level of Hb was 10.7 ± 0.6 g/dl [9.7 - 11.5]. Acute complications observed during follow-up were dominated by pneumonia and vaso-occlusive crises in both phenotypes. The overall mortality was 3% and only affected homozygous patients. Conclusion: On average, three out of four children were homozygous in our cohort. The main acute complications were infectious and vaso-occlusive. The mortality only affected homozygous carriers. Specialized follow-up has contributed to improving the quality of life of children with sickle cel

Gestational trophoblastic disease is an abnormal proliferation of trophoblastic tissue during pregnancy. It occurs in women of childbearing age, although a few cases have also been observed in post-menopausal women, although it is extremely rare in the latter. Here we describe a rare case of complete hydatidiform mole in a 56-year-old female patient who presented with genital bleeding combined with nausea and vomiting and a gravid uterus 16 cm in height. The ultrasound findings and the increase in serum β-HCG to 182566.00 mIU/ml suggested a diagnosis of complete hydatidiform mole. Given the post-menopausal state and the future risk of post-molar gestational trophoblastic neoplasia, we opted for total hysterectomy without preservation of the adnexa via a transabdominal approach, followed by antimitotic treatment with methotrexate. The uterus measured 18.45 cm × 11.18 cm with intra cavitary vesicles. Microscopic examination showed chorionic villi of variable size and shape, most of which were dilated and oedematous, associated with trophoblastic cell proliferation and haemorrhage suggestive of complete benign hydatidiform mole. Follow-up showed a consistent decrease in serum β-HCG levels and no evidence of residual disease. A suspicion of gestational trophoblastic disease should be borne in mind when evaluating a patient with peri- or post-menopausal bleeding to avoid delay in diagnosis and treatment.
