Assessment of Hand Hygiene Knowledge and Practices among Private Dental Clinics in Munshiganj, Bangladesh: A Cross-Sectional Study

Introduction: The study was performed to assess knowledge about infection control through hand-washing practices among dentists and paramedical professionals working at private dental clinics and provide help to identify and overcome obstruction towards proper hand hygiene pattern. Method: A questionnaire-based study was supervised at 15 different private dental clinics situated in the Munshiganj district of Bangladesh. Data on handwashing practices and other factors were collected from 60 samples during the months of November and December 2020. Site inspections of and washing facilities were also supervised. The data was analyzed on SPSS. Result: Majority (78.3%, 50.0% &amp; 35.0%) of the respondents strongly agreed that hand washing helps to prevent spread of infection to the patients. Less than half (48.3%) of the respondents washed their hands before wearing gloves. 31 doctors claimed that hand washing is done after termination of duty while 10 claims that they wash hands after each examination (p< 0.001). And most of the doctors use antibacterial soap (p=0.004). Conclusion: The study wraps up that most of the health care providers had the education about the advantage of handwashing, but proper technique was not followed. The reasons given for not adopting handwashing practices were shortage of time, being busy with a greater number of patients, a skin reaction, and an unsuitable atmosphere. Update Dent.

The clinical profile and associated mortality in people with and without diabetes with Coronavirus disease 2019 on admission to acute hospital services

Introduction: To assess if in adults with COVID-19, whether those with diabetes and complications (DM+C) present with a more severe clinical profile and if that relates to increased mortality, compared to those with diabetes with no complications (DM-NC) and those without diabetes. Methods: Service-level data was used from 996 adults with laboratory confirmed COVID-19 who presented to the Queen Elizabeth Hospital Birmingham, UK, from March to June 2020. All individuals were categorized into DM+C, DM-NC, and non-diabetes groups. Physiological and laboratory measurements in the first 5 days after admission were collated and compared among groups. Cox proportional hazards regression models were used to evaluate associations between diabetes status and the risk of mortality. Results: Among the 996 individuals, 104 (10.4%) were DM+C, 295 (29.6%) DM-NC and 597 (59.9%) non-diabetes. There were 309 (31.0%) in-hospital deaths documented, 40 (4.0% of total cohort) were DM+C, 99 (9.9%) DM-NC and 170 (17.0%) non-diabetes. Individuals with DM+C were more likely to present with high anion gap/metabolic acidosis, features of renal impairment, and low albumin/lymphocyte count than those with DM-NC or those without diabetes. There was no significant difference in mortality rates among the groups: compared to individuals without diabetes, the adjusted HRs were 1.39 (95% CI 0.95–2.03, p = 0.093) and 1.18 (95% CI 0.90–1.54, p = 0.226) in DM+C and DM-C, respectively. Conclusions: Those with COVID-19 and DM+C presented with a more severe clinical and biochemical profile, but this did not associate with increased mortality in this study

Mortality from gastrointestinal congenital anomalies at 264 hospitals in 74 low-income, middle-income, and high-income countries: a multicentre, international, prospective cohort study

Summary Background Congenital anomalies are the fifth leading cause of mortality in children younger than 5 years globally. Many gastrointestinal congenital anomalies are fatal without timely access to neonatal surgical care, but few studies have been done on these conditions in low-income and middle-income countries (LMICs). We compared outcomes of the seven most common gastrointestinal congenital anomalies in low-income, middle-income, and high-income countries globally, and identified factors associated with mortality. Methods We did a multicentre, international prospective cohort study of patients younger than 16 years, presenting to hospital for the first time with oesophageal atresia, congenital diaphragmatic hernia, intestinal atresia, gastroschisis, exomphalos, anorectal malformation, and Hirschsprung’s disease. Recruitment was of consecutive patients for a minimum of 1 month between October, 2018, and April, 2019. We collected data on patient demographics, clinical status, interventions, and outcomes using the REDCap platform. Patients were followed up for 30 days after primary intervention, or 30 days after admission if they did not receive an intervention. The primary outcome was all-cause, in-hospital mortality for all conditions combined and each condition individually, stratified by country income status. We did a complete case analysis. Findings We included 3849 patients with 3975 study conditions (560 with oesophageal atresia, 448 with congenital diaphragmatic hernia, 681 with intestinal atresia, 453 with gastroschisis, 325 with exomphalos, 991 with anorectal malformation, and 517 with Hirschsprung’s disease) from 264 hospitals (89 in high-income countries, 166 in middleincome countries, and nine in low-income countries) in 74 countries. Of the 3849 patients, 2231 (58·0%) were male. Median gestational age at birth was 38 weeks (IQR 36–39) and median bodyweight at presentation was 2·8 kg (2·3–3·3). Mortality among all patients was 37 (39·8%) of 93 in low-income countries, 583 (20·4%) of 2860 in middle-income countries, and 50 (5·6%) of 896 in high-income countries (p<0·0001 between all country income groups). Gastroschisis had the greatest difference in mortality between country income strata (nine [90·0%] of ten in lowincome countries, 97 [31·9%] of 304 in middle-income countries, and two [1·4%] of 139 in high-income countries; p≤0·0001 between all country income groups). Factors significantly associated with higher mortality for all patients combined included country income status (low-income vs high-income countries, risk ratio 2·78 [95% CI 1·88–4·11], p<0·0001; middle-income vs high-income countries, 2·11 [1·59–2·79], p<0·0001), sepsis at presentation (1·20 [1·04–1·40], p=0·016), higher American Society of Anesthesiologists (ASA) score at primary intervention (ASA 4–5 vs ASA 1–2, 1·82 [1·40–2·35], p<0·0001; ASA 3 vs ASA 1–2, 1·58, [1·30–1·92], p<0·0001]), surgical safety checklist not used (1·39 [1·02–1·90], p=0·035), and ventilation or parenteral nutrition unavailable when needed (ventilation 1·96, [1·41–2·71], p=0·0001; parenteral nutrition 1·35, [1·05–1·74], p=0·018). Administration of parenteral nutrition (0·61, [0·47–0·79], p=0·0002) and use of a peripherally inserted central catheter (0·65 [0·50–0·86], p=0·0024) or percutaneous central line (0·69 [0·48–1·00], p=0·049) were associated with lower mortality. Interpretation Unacceptable differences in mortality exist for gastrointestinal congenital anomalies between lowincome, middle-income, and high-income countries. Improving access to quality neonatal surgical care in LMICs will be vital to achieve Sustainable Development Goal 3.2 of ending preventable deaths in neonates and children younger than 5 years by 2030

Type 2 Diabetes Mellitus and Impaired Glucose Regulation in a multi-ethnic population

The incidence of Type 2 Diabetes Mellitus (T2DM) is increasing rapidly, therefore there is a need to detect this disease earlier and more efficiently, and also to identify novel risk factors that may aid both its detection and prevention. Aims: 1) To discuss the benefits and disadvantages of using HbA1c for diagnosis of T2DM and impaired glucose regulation (IGR). 2) To explore the impact on prevalence of using HbA1c to detect T2DM and IGR in global and local populations. 3) To determine if diagnostic cut-points are equivalent in different ethnic groups 4) To determine the use of the triglyceride-to-HDL ratio and its association with insulin resistance and whether statins and liver enzymes predict T2DM. 5) To investigate if Vitamin D deficiency has a role in the prevention of T2DM by designing a 6 month randomised controlled trial on vitamin D replacement. Key findings: 1) Using HbA1c for diagnosis has some logistical advantages over glucose testing, but may not detect the same people as having T2DM or IGR. 2) In Leicestershire, using HbA1c will increase numbers of people with T2DM and IGR. On global level, there will be regional variation on the effect on prevalence. 3) HbA1c, fasting and two hour plasma glucose are independently higher in South Asians (SA). Complications of T2DM may begin earlier in SA. 4) The triglyceride-to-HDL ratio associates with insulin resistance in Europeans and SA men but not women. Statin therapy reduces the risk of incident T2DM. Liver enzymes predict T2DM in Europeans but not SA. 5) Vitamin D deficiency may form a target for reducing insulin resistance in SA – the final results of the VITALITY study in 2015 will contribute to evidence base in this area. Conclusions: In this thesis I have explored new ways of detecting T2DM and IGR by using HbA1c and what impact this may have; also novel risk factors for T2DM have been investigated that may help improve methods of both earlier detection and prevention of T2DM

The links between sleep duration, obesity and type 2 diabetes mellitus.

Global rates of obesity and type 2 diabetes mellitus (T2DM) are increasing globally concomitant with a rising prevalence of sleep deprivation and sleep disorders. Understanding the links between sleep, obesity and T2DM might offer an opportunity to develop better prevention and treatment strategies for these epidemics. Experimental studies have shown that sleep restriction is associated with changes in energy homeostasis, insulin resistance and β-cell function. Epidemiological cohort studies established short sleep duration as a risk factor for developing obesity and T2DM. In addition, small studies suggested that short sleep duration was associated with less weight loss following lifestyle interventions or bariatric surgery. In this article, we review the epidemiological evidence linking sleep duration to obesity and T2DM and plausible mechanisms. In addition, we review the impact of changes in sleep duration on obesity and T2DM

Sleep behaviours and associated habits and the progression of pre-diabetes to type 2 diabetes mellitus in adults:A systematic review and meta-analysis

INTRODUCTION: Certain sleep behaviours increase risk of type 2 diabetes mellitus (T2DM) in the general population, but whether they contribute to the progression from pre-diabetes to T2DM is uncertain. We conducted a systematic review to assess this. METHODS: Structured searches were performed on bibliographic databases (MEDLINE, EMBASE and CINAHL) from inception to 26/04/2021 for longitudinal studies/trials consisting of adults⩾18 years with pre-diabetes and sleep behaviours (short or long sleep duration (SD), late chronotype, insomnia, obstructive sleep apnoea, daytime napping and/or night-shift employment) that reported on incident T2DM or glycaemic changes. The Newcastle-Ottawa Scale was used for quality assessment. RESULTS: Six studies were included. Meta-analysis of three studies (n = 20,139) demonstrated that short SD was associated with greater risk of progression to T2DM, hazard ratio (HR) 1.59 (95% CI 1.29-1.97), I(2) heterogeneity score 0%, p < 0.0001, but not for long SD, HR 1.50 (0.86–2.62), I(2) heterogeneity 77%, p = 0.15. The systematic review showed insomnia and night-shift duty were associated with higher progression to T2DM. Studies were rated as moderate-to-high quality. CONCLUSIONS: Progression from pre-diabetes to T2DM increases with short SD, but only limited data exists for insomnia and night-shift duty. Whether manipulating sleep could reduce progression from pre-diabetes to T2DM needs to be examined
