In June 2022, Thailand legalized recreational cannabis. Currently, cannabis is now the most consumed drug. Cannabis usage can increase inflammatory responses in the respiratory tract. Sharing of cannabis waterpipes has been linked to increased tuberculosis risks. Using a national in-patient databank, we aimed to 1) describe the spatiotemporal corre...

Introduction Tuberculosis (TB) is a chronic lung disease caused by Mycobacterium tuberculosis. Tobacco smoking and sharing of instruments have been reported to increase TB risk. In 2022, cannabis was legalized in Thailand. To address for the potential increase in cannabis use after legalization and the reported increased TB risk associated with can...

Background: To compare the differences in child development between children who contracted COVID-19 after February 1st, 2022, the period when the B.1.1.529 variant outbreak began to peak in Thailand, and those who did not. Methods: A prospective cohort study was conducted in an outpatient pediatric clinic at a tertiary hospital in southern Thai...

Introduction: Evidence suggests potential neurological complications of coronavirus disease 2019 (COVID-19), particularly in adults. While case series have hinted at associations between COVID-19 and neurological disorders (NDs) in children, the extent of this link remains unclear. This study investigates temporal trends in NDs during the pandemic...

Background Thailand recently decriminalized ( de facto legalized) cannabis use and sales. However, nationally representative data are scarce with regard to cannabis use behaviors and its association with cannabis outlet density. The objectives of this study are: (1) to describe the prevalence of cannabis use behaviors and cannabis use disorder amon...

Background: KRAS mutations (KRASmut) drive tumorigenesis through various signaling pathways that are associated with worse survival in colorectal cancer patients (CRC). Immune evasion is a hallmark of KRAS-driven cancer, but the role of KRASmut in the regulation of the immune response is unclear, particularly in the tumor microenvironment (TME), wh...

Simple Summary The poor prognosis outcome of patients with KRAS mutations (KRASmut) was correlated with an immunosuppressive tumor microenvironment (TME). At the gene expression level and pathway analysis, KRASmut tumor activates TGFβ signaling to reduced proinflammatory and cytokine gene signatures. Spatial profiling in the TME region of KRASmut,...

Space spraying is a common vector control measure used to suppress Aedes aegypti mosquito populations during outbreaks of vector-borne diseases such as dengue. Space spraying can be conducted inside or outside the household or both. The current study assessed the effectiveness of space-spraying in reducing vector populations in an active endemic se...

Microscopic observation of mosquito species, which is the basis of morphological identification, is a time-consuming and challenging process, particularly owing to the different skills and experience of public health personnel. We present deep learning models based on the well-known you-only-look-once (YOLO) algorithm. This model can be used to sim...

Background The comorbid presence of tuberculosis and diabetes mellitus has become an increasingly important public health threat to the prevention and control of both diseases. Thus, household contact investigation may serve a dual purpose of screening for both tuberculosis and diabetes mellitus among household contacts. We therefore aimed to evalu...
