This study explored the association between BMI and COVID-19 positive status in a tertiary care hospital from New Delhi.

Three hundred and seventy nine adult patients who presented to COVID-19 screening outpatient department of the hospital were interviewed over the phone regarding their body weight and height. The COVID-19 RT-PCR report of the patients was extracted from the hospital information system.

The mean BMI and the prevalence of obesity was observed to be higher in individuals who were detected to be COVID-19 RT-PCR positive as compared to those who were negative. With every one-unit increment in BMI above 23kg/m

, the odds of being COVID-19 positive increased by 1.8 times among these patients.

The findings suggest a dose-response association between BMI and the odds of COVID-19 infection in individuals with excess weight.

to determine the oral health practices in patients with DM and to identify their perspectives on treatment-seeking for oral health.

We conducted a cross-sectional study in the diabetes clinic of a government hospital in Delhi, India. Data was collected through face-face interviews with the patients.

We enrolled a total of 339 participants having a mean (SD) age of 46.1 (5.4) years. An optimal glycemic control was present in 109 (32.2%) participants. Self-reported poor or very poor condition of teeth and gums was reported by 161 (47.5%) and 69 (20.35%) participants, respectively. The awareness that DM worsens oral health was correctly reported by 15.2% participants. The prevalence of twice-daily brushing was 18.6%, and 15.6% participants underwent a dental examination in the previous 12 months.

There exists a high prevalence of poor oral care despite unsatisfactory oral health status among patients with DM in India.

We recruited 339 patients with DM in Delhi, India. Twice-daily brushing was practiced by 18.6% participants. Self-reported poor or very poor condition of teeth and gums was reported by 47.5% and 20.3% participants, respectively. Patients avoided dental visits when asymptomatic, if not referred and due to fatalistic health beliefs.

Tailgating (i.e. driving at an unsafe following distance) is both endemic and a leading cause of rear-end crashes. Similarly, drivers' decisions about when to merge with a stream of traffic are likely to influence crash risk. Baxdrostat Inhibitor Consistent with this, it has been shown that crashes are more common at intersections where drivers more frequently have to slow for vehicles pulling out into insufficient gaps. Therefore, the development of reliable and valid measures of both of these driving behaviours would facilitate further crash prevention research. Given the problems associated with assessing these behaviours during real driving, we developed new video-based measures. In our new following distance measure, participants view videos shot from the perspective of a driver who is following another vehicle at a range of distances across a variety of traffic environments. On each trial, participants report their own minimum comfortable following distance relative to the following distance depicted in the video. In our new test of gap acceptance behaviour, participants view a series of video clips and indicate when they would pull out into the approaching stream of traffic shown in each clip. The two new measures each yielded reliable data, and we found that young drivers made riskier choices than older drivers for both following distance and gap acceptance. These age-related differences are consistent with those found in observational studies of real driving, supporting the proposal that the new tests could potentially be used as proxies for these crash-related driving behaviours in both lab-based research and large-scale online studies.An advanced molecularly imprinted electrochemical sensor with high sensitivity and selectivity for the detection of Human immunoglobulin G (IgG) was successfully constructed. With acrylamide imprinting systems, surface imprinting on the nanoparticles CuFe2O4 targeted at IgG was employed to prepare molecularly imprinted polymer, which served as recognition element for the electrochemical sensor. Furthermore, the sensor harnessed a molybdenum disulfide (MoS2)@nitrogen doped graphene quantum dots (N-GQDs) with ionic liquid (IL) nanocomposite for signal amplification. Under optimized experimental conditions, the sensor shortened the response time to less than 8 min, and the response was linear at the IgG concentration of 0.1-50 ng·mL-1 with a low detection limit of 0.02 ng·mL-1 (S/N = 3). Our findings suggested that, the sensor exhibited high detectability and long-time stability. The satisfactory results of human serum sample analysis showed that the developed IgG sensor had promising potential clinical applications in detecting IgG content.A polydopamine decorated reduced oxide graphene (rGO@PDA) on carbon cloth (CC) as microbial fuel cell (MFC) anode was prepared by using dopamine polymerized reduction of oxide graphene. The anodes provided superhydrophilicity, high conductivity, good biocompatibility and long-term stability due to the combination of inorganic/organic components. These components and the resulting structure promoted enhancement of bacteria growth and enrichment, accelerated extracellular electron transfer between bacteria and anode surface, gained a high-performance rGO@PDA/CC MFC. The device achieved a short startup time of 18 h, maximum power density of 988.1 ± 5.2 mW·m-2 and Congo red decolorization efficiency of 89.7 ± 2.4% within 24 h. When Congo red and sodium acetate were continuously degraded, removal efficiency of chemical oxygen demand increased 77.8 ± 3.5% and 88.5 ± 5.8%, respectively. Thus, the synergistic effect of rGO and PDA effectively enhanced startup speed, power generation and pollutant degradation. The degradation products of Congo red were analyzed by mass spectrometry.
