There are several ways by which aging is identified, of which graying of hair is perhaps the most common way. Nowadays, graying of hairs, which was expected to occur after 40s, can be easily observed among younger age group, even before 20s. The present study aims to estimate the prevalence of graying of hairs and its correlates among young adults in Srinagar, Uttarakhand, India.
A community-based cross-sectional study was conducted among 384 young adults between 15 and 30-year age group in the urban area of Srinagar tehsil of Pauri district. Graying of hair was assessed on the basis of the number of white hairs on examination of scalp.
The prevalence of premature graying of hairs (PMGHs) was found to be 27.3%. Binary logistic regression analysis showed that a paternal history of PMGH, history of smoking, maternal history of PMGH, sunlight exposure, and body mass index were significant predictors of PMGH.
The factors found associated could be better determined through a follow-up study which could not be done in the current study. The present study was carried in a tehsil of one district of Uttarakhand therefore has limited external validity.
The present study highlights the importance of maintaining a healthy lifestyle as well as adequate exposure to sunlight in preventing PMGH.
The present study highlights the importance of maintaining a healthy lifestyle as well as adequate exposure to sunlight in preventing PMGH.Alopecia areata (AA), an unpredictable, nonscarring hair loss, is commonly perceived as a cosmetic, rather than medical, concern. However, substantial evidence exists describing the negative impact on quality of life, as the disease affects patients personally, socially, financially, and physically. Over time, the cumulative disability may perpetuate poor confidence, social disconnection, negative coping strategies, and failure to achieve a full life potential. Here, we describe the cumulative life course impairment (CLCI) of AA by examining the complex interaction of (1) stigmatization, (2) physical and psychiatric comorbidities, and (3) coping strategies. The model aggregates existing cross-sectional data, which have previously captured disease burden only as snapshots in time. Thus, by examining cumulative effects, the CLCI model serves as a proxy for longitudinal data to better describe life course epidemiology of the disease.Soft tissue aneurysmal bone cysts (STABCs) are extremely rare extraosseous counterpart of aneurysmal bone cyst (ABC), with close resemblance to histo-morphologic characteristics of ABC. Here we would like to report a 13-year-old female patient, who presented with a large mass, occupying the entire left hemithorax. Patient underwent resection of the thoracic mass. On histopathological examination, it was found to be a soft tissue ABC. It is a very rare tumor and until date 28 cases have been reported in English literature, to the best of our knowledge. On review of the literature, we found this to be the first case of STABC reported in thoracic cavity. The objective of this case presentation is to provide information regarding clinical presentation, radiological and pathological features, and course of management for this rare disease. Soft tissue ABCs are a new class of tumors, so more extensive research is required to establish standard guidelines for their diagnosis and management, to yield better prognosis.
Medical statistics is one of the "milestones" of current medical systems. It is the foundation for many protocols, including medical care systems, government recommendations, epidemic planning, etc. At this time of global COVID-19, credible data on epidemic spread can help governments make better decisions. This study's aim is to evaluate the cyclicity in the number of daily diagnosed coronavirus patients, thus allowing governments to plan how to allocate their resources more effectively.
To assess this cycle, we consider the time series of the first and second differences in the number of registered patients in different countries. The spectral densities of the time series are calculated, and the frequencies and amplitudes of the maximum spectral peaks are estimated.
It is shown that two types of cycles can be distinguished in the time series of the case numbers. Cyclical fluctuations of the first type are characterized by periods from 100 to 300 days. Cyclical fluctuations of the second type are characterized by a period of about seven days. For different countries, the phases of the seven-day fluctuations coincide. learn more It is assumed that cyclical fluctuations of the second type are associated with the weekly cycle of population activity.
These characteristics of cyclical fluctuations in cases can be used to predict the incidence rate.
These characteristics of cyclical fluctuations in cases can be used to predict the incidence rate.When the entire world is eagerly waiting for a safe, effective and widely available COVID-19 vaccine, unprecedented spikes of new cases are evident in numerous countries. To gain a deeper understanding about the future dynamics of COVID-19, a compartmental mathematical model has been proposed in this paper incorporating all possible non-pharmaceutical intervention strategies. Model parameters have been calibrated using sophisticated trust-region-reflective algorithm and short-term projection results have been illustrated for Bangladesh and India. Control reproduction numbers ( R c ) have been calculated in order to get insights about the current epidemic scenario in the above-mentioned countries. Forecasting results depict that the aforesaid countries are having downward trends in daily COVID-19 cases. Nevertheless, as the pandemic is not over in any country, it is highly recommended to use efficacious face coverings and maintain strict physical distancing in public gatherings. All necessary graphical simulations have been performed with the help of Caputo-Fabrizio fractional derivatives. learn more In addition, optimal control strategies for fractional system have been designed and the existence of unique solution has also been showed using Picard-Lindelof technique. learn more Finally, unconditional stability of the fractional numerical technique has been proved.
The dance teacher's own body is considered to be the central working instrument within the movement mediation. Up to now there is alack of knowledge about the subjective perception of one's own occupationally associated health and satisfaction as well as the identification of occupational characteristics that are detrimental to health.
Within the framework of aquestionnaire-based cross-sectional survey, acohort of dance teachers in Germany were investigated about dimensions of their own health and general job satisfaction in connection with their profession as adance teacher. link2 Likert scales were primarily used for these assessments. Additionally, general anthropometric and sociodemographic characteristics were recorded. link2 Beside examining the overall cohort, gender-specific differences were tested. The statistical analysis included
= 232 dance teachers (male 51/female 181) aged 43.1 ± 11.0years.
The general state of health was rated as satisfactory (26.1%) to very good (14.7%) by 85.3% of those surveyedf general satisfaction and a positive perception of one's own state of health. A confirmation of these positive results by injury and illness statistics is still pending. In addition, an improvement in work organization and economic aspects would be desirable.
COVID-19 is an infectious disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). link3 The virus is transmitted through respiratory droplets and by physical contact from contaminated surfaces to the mucosa. Its route of transmission has caused a significant challenge in medical and dental healthcare.
This article aims to review the literature and information available on the provision of paediatric dental treatment during and post-pandemic and to provide specific recommendations on the safe provision of paediatric dental care.
Children infected by SARS-CoV-2 have no or milder COVID-19 symptoms and are potential vectors in spreading the disease. Routine dental treatment is suspended in many countries because of the increased risk of cross-infection in dental practices. Only emergency dental care is provided for urgent conditions. It is necessary to gradually reinstate regular dental care to paediatric patients and maintain their good oral health. To control the disease transmission ande prioritized to patients in urgent needs and aerosol-generating procedures should be minimized.The COVID-19 pandemic has raised concern of viral spread within buildings. Although near-field transmission and infectious spread within individual rooms are well studied, the impact of aerosolized spread of SARS-CoV-2 via air handling systems within multiroom buildings remains unexplored. This study evaluates the concentrations and probabilities of infection for both building interior and exterior exposure sources using a well-mixed model in a multiroom building served by a central air handling system (without packaged terminal air conditioning). In particular, we compare the influence of filtration, air change rates, and the fraction of outdoor air. When the air supplied to the rooms comprises both outdoor air and recirculated air, we find filtration lowers the concentration and probability of infection the most in connected rooms. link3 We find that increasing the air change rate removes virus from the source room faster but also increases the rate of exposure in connected rooms. Therefore, slower air change rates reduce infectivity in connected rooms at shorter durations. We further find that increasing the fraction of virus-free outdoor air is helpful, unless outdoor air is infective in which case pathogen exposure inside persists for hours after a short-term release. link2 Increasing the outdoor air to 33% or the filter to MERV-13 decreases the infectivity in the connected rooms by 19% or 93% respectively, relative to a MERV-8 filter with 9% outdoor air based on 100 quanta/h of 5 μm droplets, a breathing rate of 0.48 m3/h, and the building dimensions and air handling system considered.Influenza and COVID-19 are infectious diseases with significant burdens. link3 Information and awareness on preventative techniques can be spread through the use of social media, which has become an increasingly utilized tool in recent years. This study developed a dynamic transmission model to investigate the impact of social media, particularly tweets via the social networking platform, Twitter on the number of influenza and COVID-19 cases of infection and deaths. We modified the traditional Susceptible-Exposed-Infectious-Recovered (SEIR-V) model with an additional social media component, in order to increase the accuracy of transmission dynamics and gain insight on whether social media is a beneficial behavioral intervention for these infectious diseases. The analysis found that social media has a positive effect in mitigating the spread of contagious disease in terms of peak time, peak magnitude, total infected, and total death; and the results also showed that social media's effect has a non-linear relationship with the reproduction number R 0 and it will be amplified when a vaccine is available.
