TL;DR: It is indicated that HAdV-11 strain QS, isolated in China, is a recombinant adenovirus of HAdv-14, and the recombination analyses also confirmed this finding.
Abstract: Whole-genome sequencing of human adenovirus type 11 (HAdV-11) strain QS, isolated in China, was conducted, and its sequence was compared with the sequences of strains within the species of HAdVs. The HAdV-11 QS genome contains 34,755 nucleotides. Similar to the other HAdV subgenus B sequences, the HAdV-11 QS genome coded 37 functional proteins and could be divided into four early, two intermediate, and five late transcription regions. The amino acid sequences of the fiber and the hypervariable regions (HVRs) within the hexon gene of HAdV-11 QS were identical to the corresponding sequences of the HAdV-11a strain; further analyses that compared those amino acid sequences with the amino acid sequences of the HAdV species subgenus B:2 strains revealed that the highest degree of homology (>99.2%) existed between HAdV-11 QS and the prototypical HAdV-14 strain, except for a few coding sequences of HVRs within the hexon gene, DNA polymerase, pVI, and pre-terminal protein. This indicate that HAdV-11 strain QS, isolated in China, is a recombinant adenovirus of HAdV-14, and the recombination analyses also confirmed this finding. It is difficult to clarify the time and manner of the recombination, and further investigations are required to determine whether the emergence of recombination between HAdV-11a and HAdV-14 might increase virulence, thereby posing a new global challenge with regard to acute respiratory diseases in the near future.

TL;DR: The prevalence of periodontitis is very high among adults in mainland China and is associated with age and smoking status, and current and former smokers exhibited significantly greater disease severity than non-smokers after adjustment for confounders.
Abstract: Aim To evaluate periodontal conditions in adults in mainland China based on data from the 4th National Oral Health Survey. Materials and methods Data of adult subjects (35- to 44-year-old group [N = 4409], 55- to 64-year-old group [N = 4622], and 65- to 74-year-old group [N = 4428]) were analysed. Demographic, socio-economic, personal habit, dental history, and health attitude data were obtained using a questionnaire. Periodontal condition was assessed using the standardized case definitions of the 2018 classification scheme. A multivariate analysis was performed to investigate the relationship between periodontitis severity and age, smoking status, gender, and region using generalized additive models after adjusting for confounders. Results The frequency of subjects with periodontitis was 52.8%, 69.3%, and 64.6% in the three age groups, respectively. The frequency of subjects with severe periodontitis (stage III or IV) was 10.6%, 37.3%, and 43.5% in the three age groups, respectively. The severity of periodontal disease was positively associated with age. Current and former smokers exhibited significantly greater disease severity than non-smokers after adjustment for confounders. No significant difference of severity was found between males and females. Conclusion Within the limitations of the study, the prevalence of periodontitis is very high among adults in mainland China. Periodontal status is associated with age and smoking status.

TL;DR: Male and the elderly lung cancer patients were more sensitive to the short-term effect of air pollution, and more attentions should be paid for the high PM2.5, PM10, and O3 levels during the warm season in Beijing, and high PM3.5 and PM10 during the cool season in Chongqing and Guangzhou.

TL;DR: In this article, the authors investigated how much change in mean body mass index (BMI) explains changes in the prevalence of underweight, obesity, and severe obesity in different regions using data from 2896 population-based studies with 187 million participants.
Abstract: From 1985 to 2016, the prevalence of underweight decreased, and that of obesity and severe obesity increased, in most regions, with significant variation in the magnitude of these changes across regions. We investigated how much change in mean body mass index (BMI) explains changes in the prevalence of underweight, obesity, and severe obesity in different regions using data from 2896 population-based studies with 187 million participants. Changes in the prevalence of underweight and total obesity, and to a lesser extent severe obesity, are largely driven by shifts in the distribution of BMI, with smaller contributions from changes in the shape of the distribution. In East and Southeast Asia and sub-Saharan Africa, the underweight tail of the BMI distribution was left behind as the distribution shifted. There is a need for policies that address all forms of malnutrition by making healthy foods accessible and affordable, while restricting unhealthy foods through fiscal and regulatory restrictions.
