The COVID-19 pandemic has sparked unprecedented public health and social measures (PHSM) by national and local governments, including border restrictions, school closures, mandatory facemask use and stay at home orders. Quantifying the effectiveness of these interventions in reducing disease transmission is key to rational policy making in response to the current and future pandemics. In order to estimate the effectiveness of these interventions, detailed descriptions of their timelines, scale and scope are needed. The Health Intervention Tracking for COVID-19 (HIT-COVID) is a curated and standardized global database that catalogues the implementation and relaxation of COVID-19 related PHSM. With a team of over 200 volunteer contributors, we assembled policy timelines for a range of key PHSM aimed at reducing COVID-19 risk for the national and first administrative levels (e.g. provinces and states) globally, including details such as the degree of implementation and targeted populations. We continue to maintain and adapt this database to the changing COVID-19 landscape so it can serve as a resource for researchers and policymakers alike.

The study was carried out in 200 male volunteers. They were divided into two groups. The study group was exposed to noise levels of more than 80 dB(A) for more than 8 hours a day for a period of 6 months, working in the steel and hammer industry, whereas the control group was working under normal conditions. The mean age of subjects was 33.33 + 0.867 years and the mean noise level to which they were exposed was 90.34 + 0.781 dB(A). Various autonomic function tests were carried out in both the groups and results were analyzed using Z test. Heart rate was recorded on cardiofax ECG machine and blood pressure (BP) was recorded using sphygmomanometer. The tests depicted significant increase in the mean resting heart rate and the heart rate response to standing (P=0.000), 30:15 ratio (P=0.002), the valsalva ratio (P=0.017), the % change in diastolic BP response to standing (P=0.000) and valsalva maneuver (P=0.000), the systolic BP and diastolic BP after cold pressor test (P=0.000) in study group as compared to the control group. The significant higher results in study group may be attributed to increased sympathetic activity. Thus, noise presents as a significant health hazard. It is recommended that maximum allowable duration of exposure should be reviewed and strictly followed.

BackgroundThere is currently conflicting evidence surrounding the effects of obesity on postoperative outcomes. Previous studies have found obesity to be associated with adverse events, but others have found no association. The aim of this study was to determine whether increasing body mass index (BMI) is an independent risk factor for development of major postoperative complications.MethodsThis was a multicentre prospective cohort study across the UK and Republic of Ireland. Consecutive patients undergoing elective or emergency gastrointestinal surgery over a 4‐month interval (October–December 2014) were eligible for inclusion. The primary outcome was the 30‐day major complication rate (Clavien–Dindo grade III–V). BMI was grouped according to the World Health Organization classification. Multilevel logistic regression models were used to adjust for patient, operative and hospital‐level effects, creating odds ratios (ORs) and 95 per cent confidence intervals (c.i.).ResultsOf 7965 patients, 2545 (32·0 per cent) were of normal weight, 2673 (33·6 per cent) were overweight and 2747 (34·5 per cent) were obese. Overall, 4925 (61·8 per cent) underwent elective and 3038 (38·1 per cent) emergency operations. The 30‐day major complication rate was 11·4 per cent (908 of 7965). In adjusted models, a significant interaction was found between BMI and diagnosis, with an association seen between BMI and major complications for patients with malignancy (overweight: OR 1·59, 95 per cent c.i. 1·12 to 2·29, P = 0·008; obese: OR 1·91, 1·31 to 2·83, P = 0·002; compared with normal weight) but not benign disease (overweight: OR 0·89, 0·71 to 1·12, P = 0·329; obese: OR 0·84, 0·66 to 1·06, P = 0·147).ConclusionOverweight and obese patients undergoing surgery for gastrointestinal malignancy are at increased risk of major postoperative complications compared with those of normal weight.

BackgroundThe practice of young adults smoking e-cigarette may have been adopted as a way of smoking cessation or just to follow a trend. Most people still remain unaware of the detrimental effects of e-cigarette. This study was carried out to assess the prevalence of the habit of smoking e-cigarette and the awareness of its harmful effects among adults aged 18–23 years.MethodsA questionnaire adopted from a study conducted in Italy was used in the study following due permission. After taking their consent, participants were requested to fill the survey irrespective of their smoking status.ResultsIn total the study comprised 710 participants aged 20.7 ± 1.7 years (females = 412 and males = 298) from six countries. Most respondents were from India followed by the USA and then the UK. The most common mode of information for the participants on the existence of e-cigarette was from the family members, friends followed by Internet search engines and TV/newspaper advertisements. Among the participants, e-cigarette had a prevalence of 5.63%. Among these, 26 participants were using e-cigarette for less than 1 year and 2 participants for more than 5 years. E-cigarette smokers also experienced sore throat, cough, headache, dizziness and sleeplessness.ConclusionMajority of the young population was unaware about the use and harmful effects of e-cigarette.

Background and Aims: Faith healing is a method of treating illnesses through the exercise of faith rather than medical methods. The current study was done with the objective to find out demographic variables of faith healers, various conditions for which the people approach them, various practices and processes used and to look for scope of integrated approach to healthcare with faith healers. Settings and Design: RHTC village was a sub center village of PHC Morad. Hence, for the study, all the villages which comes under PHC Morad were selected. The design of the study was a cross-sectional study. Methods and Material: The study was a cross sectional study where faith healers were interviewed based on a semi structured questionnaire comprising of both close and open-ended questions. Statistical Analysis Used: Absolute numbers. Results: Different reasons for which the persons usually came for ranged from supernatural possession, unemployment, family problems etc., and various different processes were used by these healers to solve the problems included giving charms and amulets, personal sacrifices like “ baddha” (Nischay/praan) and many others. Conclusion: The study concludes that faith healers in many conditions and situations became the first point of contact as the faith of the community in these faith healers is deeply rooted.
