Multidrug-resistant tuberculosis (MDR-TB) has imposed a significant economic and health burden worldwide, notably in China. Using whole genome sequence, we sought to understand the mutation and transmission of MDR-TB in Shandong. A retrospective study of patients diagnosed with pulmonary tuberculosis in Shandong from 2009 to 2018 was conducted.

Growing evidence has found the health protective effects of greenness exposure on tuberculosis (TB) and the impact of ambient air pollutants on TB drug-resistance. However, it remains unclear whether residential greenness is also beneficial to reduce TB drug-resistance, and whether air pollution modify the greenness-TB resistance relationship. We enrolled 5006 newly-diagnosed TB patients from Shandong, China, during 2014 to 2021.

Article Synopsis
  • * Researchers analyzed whole genome sequences from over 3,200 TB isolates in China, identifying transmission clusters and assessing mutations in PKS genes between clustered and non-clustered isolates.
  • * Findings revealed that specific PKS mutations (like ppsA, pks12, and pks13) are associated with increased transmissibility and could be targeted for future drug development.

Article Synopsis
  • Researchers examined the genetic diversity and transmission patterns of multidrug-resistant tuberculosis (MDR-TB) in China to better understand the factors contributing to its epidemic.
  • The study analyzed 1,313 MDR-TB strains using whole genome sequencing and found that most strains belong to lineage 2.2.1, which is notably linked to frequent transmission.
  • Results indicated that this lineage has a strong presence across various regions in China, and specific genetic mutations associated with drug resistance may enhance their spread without significantly impacting the bacteria's fitness.

Article Synopsis
  • The study investigates how Mycobacterium tuberculosis spreads and migrates within China by analyzing a large dataset of tuberculosis strain genomes.
  • It found that lineage 2 (L2), especially sublineage 2.2.1, is the most prevalent and has higher transmissibility compared to other strains, showing significant cross-regional spread.
  • The research highlights the public health implications of the L2.2.1 strain, as it poses a considerable challenge to tuberculosis control efforts in the country.

Background: Immune checkpoint inhibitors (ICIs) have changed the treatment pattern of advanced and metastatic NSCLC. A series of ICI based therapies have emerged in the first-line treatment field, but the comparative efficacy was unclear.

Method: We searched multiple databases and abstracts of major conference proceedings up to Apri1, 2022 for phase III randomised trials of advanced driver-gene wild type NSCLC patients receiving first-line therapy.

Article Synopsis
  • - The study investigates the impact of the Omicron variant of COVID-19 in six countries—India, Indonesia, Nepal, Malaysia, Bangladesh, and Myanmar—focusing on infection fatality rates (IFR) and the reproduction number related to the virus.
  • - A specialized model was developed to analyze the pandemic's multiple waves, incorporating factors like immune evasion and the Omicron variant's transmissibility, leading to estimates of IFR between 0.016% and 0.136% and reproduction numbers up to 9.
  • - The findings indicate that the Omicron variant has led to new pandemic waves in these countries, but higher vaccination rates and immunity could help mitigate its impact in the future.

Background: With the widespread use of steroids and immunosuppressants in mainland China, disseminated strongyloidiasis is becoming a severely underestimated tropical disease due to the lack of disease-specific manifestations and well-established diagnostic methods.

Case Presentation: Here, we report a 70-year-old woman who was diagnosed with Guillain-Barré syndrome due to autonomic disturbance, symmetrical bulbar palsy, and lower-motor-nerve damage in the extremities; her symptoms continued to worsen after hormone and immunoglobulin therapy. Later, parasitic larvae were found in the patient's gastric fluid, and metagenomic Next Generation Sequencing (mNGS) detection of bronchoalveolar-lavage fluid also found a large number of .

Background: Tuberculosis (TB) is one of the main infectious diseases that seriously threatens global health, while diagnostic delay (DD) and treatment dramatically threaten TB control.

Methods: Between 2005 and 2017 in Shandong, China, we enrolled pulmonary tuberculosis (PTB) patients with DD. DD trends were evaluated by Joinpoint regression, and associations between PTB patient characteristics and DD were estimated by univariate and multivariate logistic regression.

Tuberculosis (TB) incidence has been in steady decline in China over the last few decades. However, ongoing demographic transition, fueled by aging, and massive internal migration could have important implications for TB control in the future. We collated data on TB notification, demography, and drug resistance between 2004 and 2017 across seven cities in Shandong, the second most populous province in China.

Introduction: Tuberculosis is one of the main infectious diseases threatening global health, which is also the main cause of death from a single source of infection (above HIV/AIDS). China is a country with a high burden of tuberculosis in the world, ranking only behind India and Indonesia. However, there are few ecological studies on the burden of tuberculosis in China.

Article Synopsis
  • Pulmonary sarcomatoid carcinoma (PSC) is a rare and aggressive form of non-small cell lung carcinoma that typically has a poor prognosis and low response to standard treatments.
  • Recent advancements in gene sequencing and immunotherapy have opened new treatment options for PSC, particularly for patients with overexpression of programmed death-ligand 1 (PD-L1) that may respond to PD-1 inhibitors.
  • A case study demonstrated successful treatment with tislelizumab, an anti-PD-1 therapy, in a patient with advanced PSC, suggesting a potential new avenue for treatment in similar cases.
