Background: The functional capacity of elderly patients decreases with age due to a combination of age-related decline in physiologic functions and chronic diseases. A severe decrease leads to an inability to carry out activities of daily living leading to a loss of autonomy and increased dependence. The aim of this study was to evaluate the functional capacity of the elderly followed at the Yaoundé Central Hospital. Methods: We carried out a non-probabilistic consecutive sampling of elderly patients that consulted in Yaoundé Central Hospital during a five-month’ period. Data was taken concerning their chronic conditions, use of medication, and presence of depressive symptoms (evaluated using the Geriatric Depression Scale (GDS) questionnaire). The presence of any cognitive impairment was evaluated using the Mini-Mental State Examination (MMSE). Cardiac ultrasonography and electrocardiograms were done to evaluate the cardiac morphology and physiology. Their functional capacity was assessed with the WHO Global Physical Activity Questionnaire and the six-minute walk test. A self-paced step test was equally done to estimate the maximum oxygen consumption during aerobic exercise. We carried out aunivariate, and then multivariate analyses to identify factors associated with an altered functional status. Statistical analysis was performed using the SPSS software 23.0. The threshold of significance was set at 0.05. Results: 66 participants were included (35 women) with a median age of 70 (IQR: 67 - 75) years. Among them, 39.4% were found to have an altered functional capacity, about 87.8% had at least one chronic condition and 47% had two or more. The most prevalent chronic condition was hypertension (71.2%) followed by heart failure (24.2%) and osteoarthritis (12.1%). Mild depressive symptoms were present in 1.5% of our study population. The factors associated with an altered functional capacity include age ≥ 75 years (OR = 2.9 p heart failure (OR: 3.2, p ), osteoarthriti

为了给除害灭病提供科学依据,1963年4月至11月,我们在河南平原农村的中牟县进行了蝇类的调查。观察是以笼诱法进行的。采得蝇类标本6科57种,内有9种为河南地区首次报告,1种为国内新记录,并将其中较常见的13种蝇类的季节消长作了记录。一、方法 1.调查点选择居民厨房内、外,住室内、外,牲畜房内、外,营业食堂内、外及厕所、果林等共10处。每处设置一诱蝇笼,以麦麸、糖及酵母,适当加水拌和使之发酵作为诱饵。每旬诱蝇一次,每次自早5—6时放笼,至晚6—7时收笼。 2.将每次所诱获之蝇以DDVP熏蒸杀死,在实验室进行分类登记。 3.计算方法是以某蝇种每月共诱获数除以每月总笼数,所得的商作为每月某蝇种的平均密度指数。

(一)四种来源不同的沥青(鞍山煤焦油沥青、西北玉门石油沥青、大连石油沥青、和美国亚细亚公司石油沥青)经涂抹小白鼠的实验证明具有引起皮肤各种的病理变化的作用。其中包括慢性渗出性皮炎;慢性炎性上皮结缔组织增生;良性皮肤乳头状瘤;皮肤鳞状细胞癌。此外也引起了少数的肉瘤和“肌母细胞痛”。皮肤瘤发生的潜伏期由62天至406天不等。(二)光感作用可以加剧及加速煤焦油沥青皮肤炎的进展,和发炎皮肤的角化现象。至于对沥青致癌作用本实验未能证实其有显著的影响。(三)根据四种来源不同的沥青所引起皮肤良性与恶性病变的发病率和潜伏期的长短,可将其毒性的强弱顺序排列如下:(1)鞍山煤焦油沥青,(2)美国亚细亚公司石油沥青,(3)大连石油沥青(苏联原油),(4)西北玉门石油沥青。即煤焦油沥青毒性远较石油沥青为强。国产石油沥青的毒性较外产石油沥青的毒性为弱。
