Objective To explore the association of mild cognitive impairment (MCI) with obesity level in middle and elderly population. Methods A total of 19181 subjects aged 50-85 years were collected in this study from the first and second recruitment phase of the Guangzhou Biobank Cohort Study. The subjects received face-to-face interviews to collect the detailed information on their sociodemographic background, occupational exposures, living environment, lifestyle, family and personal disease histories, and had physical examinations and tests including 12-lead ECG, chest radiograph, and pulmonary function testing. Each subject was screened for a range of fasting biochemical parameters. The cognitive ability was tested with 10-words delayed memory test. The associations between cognition function and anthropometric indices of obesity, including body mass index, waist-to-hip ratio (WHR) and waistline, were evaluated. Results Apart from fast glucose and hypertension in subjects with normal cognition function and abnormal cognition function, some lifestyle and such physiological and biochemical factors as age, education, smoking status, and drinking status were significantly different in both gender (P＜0.05). WHR was the independent risk factor of MCI in both gender (P＜0.05). Logistic regression indicated that high WHR was a risk of MCI in both gender; the greater the WHR, the poorer memory the middle and elderly population; the OR and 95％ CI was 1.57 (1.42-1.72) in female and 1.22(1.05-1.41) in male. Conclusion Centripetal obesity is associated with MCI. WHR is a sensitive indicator influencing the cognitive function in women.

Introduction: Flooding has become a major natural disaster in Malaysia in recent decades. There may be a gender difference in many aspects related to flood response and practice. This study aimed to examine the gender gap in knowledge, attitudes, and practice of flood preparedness in Malaysia. Method: This cross-sectional study was conducted among patients attending the primary care clinic at Universiti Sains Malaysia health campus, Kelantan. A validated questionnaire was used for data collection. Results: 328 subjects were recruited, 56.1% of them were females. The female respondents were younger than the males (36 vs. 41 years old). However, females have better knowledge, and practice on flood preparedness compared to male respondents. Among those, women were more aware of the local emergency plan than males (p=0.01). More female respondents kept their vaccination and personal medical records in a waterproof container or sealed plastic bag during past and future flood preparations (3-5 day supply of non-perishable food) than male respondents (p<0.05). In addition, with the practice of keeping a one-week supply of medication, and having their medical records in a waterproof container along with a first-aid kit (p=0.001). For future flood preparation, more women would filter the cloudy water through clean clothes for boiling (p=0.035). The determinants of good preparedness for future floods for female were older-age (p=0.001), blue-collar (p=0.043); whereas male were lower household income (p=0.014), being blue collar (0.014) and white collar (0.039) compared with student/retiree based on multivariate logistic regression. Conclusion: Our study reported that the determinants of good preparedness for future floods were older-age, blue-collar and having a lower-household income.

The Singapore Health Services cluster (SingHealth) radiology film archives are a valuable repository of local radiological cases dating back to the 1950s. Some of the cases in the archives are of historical medical interest, i.e. cerebral angiography in the workup of patients with hemiplegia. Other cases are of historical social interest, being conditions seen during earlier stages of Singapore's development, i.e. bound feet. The archives form a unique portal into the development of local radiology as well as the national development of Singapore. A selection from the archives is published in 2020 in commemoration of the 20th anniversary of the formation of SingHealth, the 55th National Day of Singapore, and the 125th anniversary of the International Day of Radiology. This pictorial essay comprises cardiovascular, respiratory and neurological cases from the archives.
