To report antibiotic resistance rates and trends of common ocular isolates collected over a 15-year period.

We collected 3533 isolates from July 1, 2005 to July 31, 2020. Antibiotic sensitivity was determined according to the guidelines of the Clinical and Laboratory Standards Institute. Chi-squared (



) test was used to analyze changes in antibiotic susceptibility over 15 years.

Among the 3533 isolates, the predominant pathogens were the staphylococcal species. Methicillin resistance was observed in 381

(

) isolates (46.4%) and 1888 coagulase-negative staphylococci (CoNS) isolates (61.1%), and methicillin-resistant (MR) isolates had a high probability of concurrent resistance to fluoroquinolones and aminoglycosides. The mean percentage of resistance in staphylococcal isolates did not reach statistical significance across patient age groups (

= 0.87). Methicillin resistance did not increase in the CoNS (

= 0.546) isolates, and resistance to methicillin slightly decreased among

(

= 0.04) esistance among MR staphylococci to other antibiotics. Overall, ocular resistance did not significantly change during the 15-year study period. We conclude that continued surveillance of antibiotic resistance provides critical data to guide antibiotic selection.

Antimicrobial resistance (AMR) is a major global health concern with increasing reports of microorganisms resistant to most of the available antibiotics. There are limited data on antibiotic practices, perceptions and self-medication among Ugandans, necessitating this study.

A cross-sectional study was conducted among patients at Kiruddu National Referral Hospital, Kampala, Uganda. A pre-tested interviewer administered a questionnaire that was used to collect data after an informed consent. Chi-square tests and logistic regression were used to assess associations between outcome and exposure variables. A P<0.05 was statistically significant.

A total of 279 patients (response rate=71%) with a median age of 32 years participated in the study. The majority were females (55.6%, n=155) and from the outpatient department (74.9%, n=209). Overall, 212 (76%) participants had taken an antibiotic in the past 6 months, and some 22.2% (n=47) of the participants had practiced self-medication. Male participants (adtic misuse is significant among patients in Uganda. Continuous health education programs aimed at informing the public on antimicrobial resistance, and its dangers are recommended to curtail this challenge.

There have been limited reports looking into the care of patients with asthma exacerbations admitted to tertiary hospitals in Southeast Asia. This study aims to determine the extent in which the 2019 Global Initiative for Asthma (GINA) guidelines were being met.

A retrospective study of patients with asthma exacerbations admitted to the University of Malaya Medical Centre (UMMC) and Pantai Hospital Kuala Lumpur (PHKL), Malaysia from 1 July 2019 to 31 December 2019.

There were significant numbers of patients with previous admissions for asthma in both centres, with almost 50% experiencing an exacerbation in the previous year. Approximately 75% of the patients considered their asthma to be controlled when asked, despite many of them having had a history of acute exacerbations in the previous year. When cross-checked, the level of GINA-defined asthma control remained low, with only 6.4% of the patients deemed to have good control, while asthma was partially controlled in 25.6% of the patients and uncontrolhe management of asthma exacerbations in tertiary hospitals in Southeast Asia is largely congruous with international guidelines, there is room for improvement. As there is a marked discrepancy between patient-perceived and guideline-defined asthma control, efforts to increase awareness on the dangers of uncontrolled asthma are warranted.

To investigate the role and underlying mechanism of G9a and CCDC8 in lung cancer radioresistance.

Western blotting assays were used for G9a, CCDC8, H3K9me3 expression detection. MTT assays and clone formation assays were used for measuring cell proliferation activities. Flow cytometry assays were used for cell apoptosis detection. The enrichment of H3K9me3 in CCDC8 promoter was measured by chromatin immunoprecipitation assay.

G9a and G9a-mediated H3K9me3 are upregulated in radioresistant lung cancer cells (A549/IR cell and XWLC-05/IR cell). Blocking G9a not only promotes radiosensitivity of A549/IR cell and XWLC-05/IR cell but also reduces aggressive behavior of radioresistant A549 cell/IR and XWLC-05/IR cell. In addition, G9a-controlled H3K9me3 is able to binding to the promoter of tumor suppressor gene CCDC8 and suppresses CCDC8 expression. CCDC8 dysregulation is responsible for G9a-mediated radioresistance of A549/IR cell and XWLC-05/IR cell.

G9a and H3K9me3 contribute to the lung cancer radioresistance via modulating CCDC8 expression.

Lung cancer represents one of the most frequent solid tumors. Adenocarcinoma is a common type of tumor and a significant threat to individual health globally. MicroRNAs (miRNAs) are recognized as critical governors of gene expression during carcinogenesis, while their effects on lung cancer occurrence and development are required for further investigation. Herein, the functional role of miR-210-3p and its regulation mechanism were characterized in lung cancer.

A total of 50 pairs of tumor and tumor-free lung tissues were surgically resected from lung cancer patients. read more Dual-luciferase reporter assay and RNA immunoprecipitation assay were performed to examine USF1 binding with miR-210-3p and PCGF3. Cultured human lung cancer cells A549 were assayed for viability, apoptosis, migration, and invasion in vitro by CCK-8 test, flow cytometry, transwell chamber assays, tumorigenesis, and lymph node metastasis in vivo by mouse xenograft experiments.

miR-210-3p was upregulated in lung cancer tissues. The inhibition of miR-210-3p by specific inhibitor tempered lung cancer development and metastasis in vitro and in vivo.
