“…The rest of the faculty (n=1) and students (n=16) with strong positive PPD were diagnosed as latent tuberculosis infection (LTBI). All TB cases in this outbreak were diagnosed and classified according to the national TB diagnosis and classification standards (2)(3). The screening was expanded to students and faculty members who have classrooms on the same floor with the TB cases, and 1 out of the 78 students (1.3%) was diagnosed as LTBI (Figure 1).…”

What is already known about topic?Multidrug-resistant tuberculosis (MDR-TB) has become a growing threat to public health. There were few reports about family-to-school MDR-TB outbreaks in China, especially during the coronavirus disease 2019 (COVID-19) pandemic. What is added by this report?A tuberculosis (TB) outbreak happened in Hubei Province during the COVID-19 pandemic. The transmission chain was probably from a father (MDR-TB case) with retreated TB history to his daughter, who then spread TB to her classmates. What are the implications for public health practice?We should enhance TB control both in schools and households, including strengthening TB/MDR-TB detection, health education, and ventilation. The TB contact screening cannot only be limited to outside school settings and should be conducted in the school when a TB student is absent from school for 2 or 3 months, or even longer especially during the COVID-19 pandemic.

Background:To investigate the association between TaqI polymorphism of the vitamin D receptor gene and tuberculosis (TB).Methods:A systematic search was performed in PubMed, Embase, Web of Science, Elsevier Science Direct, Cochrane Library, Chinese National Knowledge Infrastructure, Wanfang, and Chongqing VIP databases for case-control study on TaqI gene polymorphism and TB susceptivity. Quality assessment of studies was performed using the Newcastle–Ottawa Scale for the methodological assessment of case-control studies, and R 4.0.5 software was used for the meta-analysis.Results:Among the 243 selected articles, 27 in the meta-analysis. The meta-analysis showed that the TaqI gene polymorphism allene gene model (t vs T, odds ratio [OR]: 1.12, 95% confidence interval [CI]: 0.99–1.27); dominant model (tt + tT vs TT, OR: 1.12, 95% CI: 0.98–1.29); recessive model (tt vs tT + TT, OR: 1.25, 95% CI: 1.03–1.51); codominant A (tt vs TT, OR: 1.37, 95% CI: 1.00–1.87); codominant B (tT vs TT, OR: 1.09, 95% CI: 0.99–1.19). And subgroup dominant model (tt + tT vs TT, OR: 1.27, 95% CI: 1.03–1.55) in Indianas, recessive model (tt vs tT + TT, OR: 1.49, 95% CI: 1.05–2.11) in Iranians, co-dominant B (tT vs TT, OR: 1.28, 95% CI: 1.03–1.59; OR: 1.42, 95% CI: 1.05–1.93) in Indianas and Iranians.Conclusion:This meta-analysis suggests a significant association between TB and the risk of TaqI in Iranians and Indians, but the vitamin D receptor polymorphism TaqI was not associated with Chinese. Thus, validation studies will be required to confirm these findings.

“…The basin was influenced by land-derived clastic sedimentation and characterized by a semi-closed estuarine and lagoon environment during the early Paleocene-Eocene period [30]. Under the control of a subtropical arid climate, clastic rocks, gypsum rocks, and carbonate rocks were formed [43], and the Aertashen Formation underwent lagoonal and very shallow water evaporitic terrace phase sedimentation [54]. It is worth noting that evaporite rocks, such as gypsum and halite, are usually formed in closed or semi-closed basins and arid climates or strongly evaporated environments [55].…”

The Yarkand Basin, located in the southwest of the Tarim Basin, is a northeastern part of the eastern Paratethys ocean in the Paleocene, and a significant amount of evaporites, with gypsum, anhydrite, and halite as the main types, were developed in this area. These evaporites record the sedimentary environment at that time. A study was conducted on the sulfur isotopic composition of gypsum in the Paleocene of the Yarkand Basin to explore the origin of the evaporites and interpret the sedimentary environment. The experimentally measured sulfur isotope δ34SCDT values of 187 gypsum samples ranged from 6.69‰ to 25.92‰ with an average value of 18.64‰. The overall trend of the Paleocene gypsum sulfur isotopic curve is consistent with the global seawater sulfur isotopic curve, which shows a decreasing trend. In the early and middle Paleocene, the curve shows four stages of sulfur isotope increase, indicating that the sedimentary environment during that time was mainly influenced by bacterial reduction and a relatively open sedimentary environment, while the late period shows a decreasing trend, suggesting that the late period may be primarily influenced by terrigenous freshwater. In addition, the sulfur isotope value has the characteristics of decreasing from northwest to southeast of the basin, which may indicate that the sedimentary environment of Paleocene evaporites in the Yarkand Basin may also be related to paleotopography and distance from the estuary, resulting in differences in sedimentary environments. The mainly original sulfur isotope values of the Paleocene evaporites in the Yarkand Basin should be in the range of 18‰–20‰, which is a supplement to the Paleocene global paleoseawater and is of great significance for the reconstruction of the marine transgressive–regressive cycle and sulfur isotopic composition of the eastern Paratethys ocean during this period.
