The world population is aging and no country is immune to the consequences. We are not aware of any country-specific skin aging risk factors data for the Mongolian people. Thus, we aimed to study the risk factors associated with skin aging in the Mongolian population.  A population-based cross-sectional study of 2720 study participants 18 years of age and older was performed evaluating the severity of skin aging based on cutaneous microtopography. Questionnaire data and skin physiological measurements were obtained. The odds ratios for skin aging grades associated with risk factors were estimated using ordinal logistic regression. Study participant's mean age was 45 years, ranging from 18 to 87. After adjustment for known risk factors, skin aging was associated with demographic risk factors such as increasing age (aOR=1.19, 95% CI 1.18-1.20), living in an urban area (aOR=1.31, 95% CI 1.12-1.55) and working outside (aOR=1.44, 95% CI 0.88-2.39) and lifestyle factors including non-usage of sunscreen cream (aOR=1.09 95% CI 0.87-1.37), being a smoker (aOR=1.32, 95% CI 1.09-1.61), having a higher body mass index (BMI) (aOR=1.04, 95% CI 1.02-1.06) and higher levels of sun exposure time (aOR=1.03, 95% CI 1.00-1.06 ) were significantly associated with higher skin aging grades. Having dry (aOR=1.94, 95% CI 1.45-2.59) and combination skin (aOR=1.62, 95% CI 1.22-2.16) types were also independent risk factors associated with skin aging. Having very low skin surface moisture at the T-zone (aOR=2.10, 95% CI 1.42-3.11) and U-zone (aOR=1.25, 95% CI 0.95-1.65) were significantly related to skin aging. Older age, urban living, harsh working conditions, living in a ger district were independent demographic risk factors related to skin aging. Not using sunscreen cream, smoking, higher BMI, greater levels of sun exposure were significant lifestyle risk factors. Having a skin type other than normal was a physiologic risk factor for skin aging.

Background The primary goal of the presented cross-sectional observational study was to determine the clinical and demographic risk factors for adverse coronavirus disease 2019 (COVID-19) outcomes in the Pakistani population. Methods We examined the individuals (n = 6331) that consulted two private diagnostic centers in Lahore, Pakistan, for COVID-19 testing between May 1, 2020, and November 30, 2020. The attending nurse collected clinical and demographic information. A confirmed case of COVID-19 was defined as having a positive result through real-time reverse transcriptase polymerase chain reaction (RT-PCR) assay of nasopharyngeal swab specimens. Results RT-PCR testing was positive in 1094 cases. Out of which, 5.2% had severe, and 20.8% had mild symptoms. We observed a strong association of COVID-19 severity with the number and type of comorbidities. The severity of the disease intensified as the number of comorbidities increased. The most vulnerable groups for the poor outcome are patients with diabetes and hypertension. Increasing age was also associated with PCR positivity and the severity of the disease. Conclusions Most cases of COVID-19 included in this study developed mild symptoms or were asymptomatic. Risk factors for adverse outcomes included older age and the simultaneous presence of comorbidities.

SUMMARYAbout 20–90% of the world's population has had contact withToxoplasma gondiiparasites. The aim of this study was to determine the seroprevalence and risk factors associated withT. gondiiinfection in the Central Region, Ghana. A community-based cross-sectional study was conducted in three selected communities. Serum samples were tested for the presence of anti-T. gondiiIgG and IgM antibodies by ELISA. A serological criterion for seropositivity was a positive test result for any of the two anti-ToxoplasmaIgG or IgM antibodies or a combination of both. In all, 390 participants of mean age 47·0 years consisting of 118 (30·3%) males and 272 (69·7%) females were tested. The overall seroprevalence ofT. gondiiwas 85% (333/390) where fishermen, farmers and fishmongers, respectively, had the highest seropositivity. IgG and IgM antibodies were detected in 329 (84%) and 25 (6%), respectively, while both IgG and IgM antibodies were detected in 21 (5%) of the participants. Respectively, 1% (4/390) and 79% (308/390) of participants tested positive for IgM-only and IgG-only antibodies. There was a significant relationship betweenToxoplasmaseropositivity and contact with soil, presence of a cat in the surrounding area, age, sources of drinking water, level of formal education, and socioeconomic status. The results suggest that the seashore may serve as a good ground for sporulation and survival ofToxoplasmaoocysts.
