BackgroundCOVID-19 pandemic created an unprecedented disruption of daily life including the pattern of skin related treatments in healthcare settings by issuing stay-at-home orders and newly coronaphobia around the world.ObjectiveThis study aimed to evaluate whether there are any significant changes in population interest for skincare during the COVID-19 pandemic.MethodsFor the skincare, weekly RSV data were extracted for worldwide and 23 counties between August 1, 2016, and August 31, 2020. Interrupted time-series analysis was conducted as the quasi-experimental approach to evaluate the longitudinal effects of COVID-19 skincare related search queries. For each country, autoregressive integrated moving average (ARIMA) model relative search volume (RSV) time series and then testing multiple periods simultaneously to examine the magnitude of the interruption. Multivariate linear regression was used to estimate the correlation between countries’ relative changes in RSV with COVID-19 confirmed cases/ per 10000 patients and lockdown measures.ResultsOut of 23 included countries in our study, 17 showed significantly increased (p<0.01) RSVs during the lockdown period compared with the ARIMA forecasted data. The highest percentage of increments occurs in May and June 2020 in most countries. There was also a significant correlation between lockdown measures and the number of COVID-19 cases with relatives changes in population interests for skincare.ConclusionUnderstanding the trend and changes in skincare public interest during COVID-19 may assist health authorities to promote accessible educational information and preventive initiatives regarding skin problems.

Guava is a popular, export-promising, fast-growing fruit crop in Bangladesh that encompasses an important demand within the local market. We conducted a study of four types of guavas, specifically Thai guava, Strawberry guava, Kazi guava, and Deshi guava, by observing various parameters. The aim of this investigation to explore the physiochemical characteristics of the guava varieties procured from the local market of Noakhali district of Bangladesh. Physical characteristics such as weight, size, length, diameter, shape, and color were determined, as well as the nutritional status of guava varieties, including their non-reducing,reducing sugar , total sugar contents, vitamin C content, and the relationship between total sugar and vitamin C content, was assessed. According to the results, Kazi guava showed the highest fruit weight (220 gm), length (5.96 cm), and breadth (6.6 cm) compared to the other guava varieties available on the market. All the guava varieties had a similar color (green to pale green), while strawberry guava was red in color. Statistically significant variations were found among the chemical characteristics such as total sugar, reducing sugar, non-reducing sugar, total sugar, reducing sugar and the vitamin C content of various varieties. The highest value of reducing sugar (6.19%), non-reducing sugar (2.02%), and total sugar (8.55%) was found in Thai guava. Vitamin-C content was highest in Deshi guava (74.73 mg/100gm), whereas Kazi guava had the lowest value (61.20 mg/100 gm) of vitamin C content. However, this research explored that Thai guava had comparatively higher nutrition than others, but physical parameters were found to be best in the Kazi guava variety.

Objective: Covid-19 continues its negative impact on limb salvage in patients with limb ischemia and vascular trauma. Bangladesh fought the 1st and 2nd waves of the Covid-19 pandemic during April through August, 2020 and in April-May, 2021, respectively. Infections have been rising once again since early June 2021 to reach a positivity rate over 30%. With limited resources, vascular surgical care during the pandemic has been an unprecedented challenge for a developing country like Bangladesh. As a small vascular community, we have adopted a strategy focused on conserving essential resources including manpower while delivering essential vascular care. The present study evaluates the effectiveness of our pandemic-time guideline-based working strategy with a focus on limb salvage. Methods: Essential vascular services were provided by customized teams throughout the Covid-19 pandemic at two referral centers according to our working guidelines. Data were analyzed and key limb salvage outcomes compared between the two pandemic waves by chi-square test. Results: A total of 1792 vascular surgical cases were addressed during the pandemic- over 90% of which involved limb or life-saving procedures. Overall mortality was 0.6% and overall limb salvage rate for acute and Chronic Limb Threatening Ischemia (CLTI) were 95.3% and 76.8%, respectively. Limb salvage rate for CLTI was significantly higher in the 2nd wave compared with the 1st (P<0.05). Rate of Covid-19 infection among vascular workforce was about 20%. Conclusion: Emergency-focused altered working guideline has produced satisfactory results in terms of continuing emergency vascular services, improving limb salvage and safeguarding vascular workforce during Covid-19 pandemic in a developing country. Conservation of resources including manpower remains relevant in the context of a highly probable 3rd wave of infection.
