Background: Antimicrobial resistance is a public health problem that threatens the efficacy of antibiotics. Incorrect knowledge of antibiotics may lead to their inappropriate use, hinder their effectiveness, and cause antibiotic resistance. Population-based educational campaigns have been found to have either mixed or no effect on improving knowledge and appropriate antibiotic practices, suggesting the need for more targeted approaches in tailoring education for specific subpopulations. Women are the primary caregivers of their families and are more willing to contact healthcare providers. They had greater knowledge of antibiotics and better adherence to the completion of the antibiotic regimen. Therefore, they are suitable for prioritization in a campaign program.Objective: This study examined the knowledge and practices of female visitors to health centers in Malang, Indonesia with respect to antibiotic use.Methods: This cross-sectional study was conducted in Malang, Indonesia, in July and August 2018. Data were collected from 677 women. Multivariate logistic regression was performed to identify the potential factors associated with antibiotic knowledge, self-medication, and completion of antibiotic regimens.Results: Overall, 82.7% of respondents were aware that antibiotics are used against bacteria, while 38.4% reported self-medication with antibiotics and 51.7% reported completing antibiotic regimens. Women with higher education, previous antibiotic use experience, and very easy accessibility to primary doctors were more likely to have high antibiotic knowledge than those with primary education, no antibiotic use in the previous year, and easy/other level of accessibility to primary doctors. Subjects residing in urban areas and with less accessibility to primary doctors were more likely to self-medicate with antibiotics. Additionally, the completion of antibiotic regimens was positively associated with access to a primary care doctor and high antibiotic knowledge.Conclusion: IF Policymakers tend to reduce inappropriate antibiotic use among women. Priority advocates are recommended for urban residents who have experiences of antibiotic use in the previous year. It is therefore important to increase their awareness, particularly regarding diseases against which antibiotics are effective, and activities such as unnecessary use of antibiotics in healthy animals, which may affect their overall effectiveness among humans. More communication channels should be included in the overall scheme to improve the public awareness and accessibility of health professionals.

The modified dose (MD) regimen of pembrolizumab (2 mg/kg or 100 mg every 3 weeks) is an alternative option to reduce the financial burden resulting from the extremely high cost of the standard dose (SD) regimen (200 mg every 3 weeks). However, the clinical effectiveness and prognostic outcomes have not been fully elucidated in real-word clinical practice. Sixty-four consecutive patients in Taiwan receiving pembrolizumab for advanced NSCLC between 2018 and 2020 were recruited in this study. Comparisons of overall survival (OS) and progression-free survival (PFS) were performed using Kaplan–Meier survival curves. Additionally, 12 predictors, including pembrolizumab regimen, dose, neutrophil-to-lymphocyte ratio (NLR), age, sex, histopathology, smoking history, ECOG PS, EGFR mutation, PD-L1 expression, distant metastases and treatment line, were analyzed in multivariable Cox models for predicting OS and PFS. The results showed that the MD group and the SD group had similar OS and PFS, especially in patients beyond first-line treatment or with a pretreatment NLR < 5. The NLR was the only independent factor associated with both OS (adjusted HR = 0.052; p = 0.010) and PFS (adjusted HR = 0.259; p = 0.021). The results of this study assure the clinical effectiveness of MD pembrolizumab and suggest that the pretreatment NLR could highlight patients who may benefit from MD pembrolizumab.

Taste and smell dysfunction are suspected to be associated with substance use. However, representative epidemiological studies remain insufficient. This cross-sectional study explored the relationship between drug use (including cannabis or hashish, cocaine, heroin, and methamphetamine) and olfactory/gustatory dysfunction using data from the 2013–2014 National Health and Nutrition Examination Survey. In this study, participants who completed the smell examination with mean age of 59 were classified into four groups: cannabis users (n = 845), participants without cannabis use (n = 794), illicit drug users (n = 450), and participants without illicit drug use (n = 2000). Participants who completed the taste examination with mean age of 58 were also categorised into four groups: cannabis users (n = 810), participants without cannabis use (n = 714), illicit drug users (n = 428), and participants without illicit drug use (n = 1815). Logistic regression models investigated the association between cannabis or illicit drug use and smell or taste dysfunctions among study participants. Odds ratios and 95% confidence intervals were calculated. Finally, we did not find correlations between illicit drug use and dysfunction of taste or smell senses; our findings were consistent in many subgroup analyses. We recommend that further studies explore the mechanism and dose of illicit drug use that could have chemosensory impacts.
