Late-Onset Crizotinib-Associated Renal Cysts With Subsequent Regression Following Dose Reduction: A Case Report.

Crizotinib, an anaplastic lymphoma kinase (ALK)/ROS1/c-MET inhibitor, improves outcomes in ALK-positive non-small cell lung cancer (NSCLC) but can cause crizotinib-associated renal cysts (CARCs), a rare yet clinically relevant adverse effect. We report a case of a 68-year-old Korean male who developed complex renal cysts after 4 years of crizotinib therapy. Radiologic findings initially raised suspicion for either an abscess or a neoplastic lesion, leading to surgical resection.

Better Chemotherapeutic Response of Small Cell Lung Cancer in Never Smokers than in Smokers.

Background: Small cell lung cancer (SCLC) is called 'smoker's disease' because it is strongly associated with smoking and most cases occur in smokers. However, it can also occur in never smokers. We investigated the clinical features of never smokers with SCLC and compared their treatment outcomes with those of smokers with SCLC.

Impact of pyrazinamide usage on serious adverse events in elderly tuberculosis patients: A multicenter cohort study.

Background: Pyrazinamide (PZA) usage has been associated with adverse drug reactions, prompting its avoidance in treating elderly tuberculosis (TB) patients. This study aims to examine whether the administration of PZA is associated with poor outcomes during TB treatment among elderly individuals.

Methods: A retrospective analysis was undertaken on data collected from a prospective cohort conducted between July 2019 and June 2023, which involved tuberculosis patients from 18 institutions across the Republic of Korea.

The clinical characteristics associated with the ratio between the main pulmonary artery and ascending aorta diameter in patients with acute exacerbation of chronic obstructive pulmonary disease.

Background: A pulmonary artery-to-aorta (PA/A) ratio of ≥1 is a reliable indicator of pulmonary hypertension and is associated with an increased risk of acute exacerbation of chronic obstructive pulmonary disease (COPD) and long-term mortality in patients with stable COPD. However, it is unclear whether a PA/A ratio of ≥1 is associated with mortality in patients hospitalized with acute exacerbation of COPD. The purpose of this study was to evaluate the clinical course and mortality of patients with PA/A ratios of ≥1 who were hospitalized with acute exacerbation of COPD.

Association between Weight Change and Incidence of Dyslipidemia in Young Adults: A Retrospective Cohort Study of Korean Male Soldiers.

Background: Recent lifestyle changes have increased the prevalence of dyslipidemia in Korea. Young men are known to have a low awareness of dyslipidemia and a lack of motivation to maintain their weight. However, the association between weight change and dyslipidemia in young adults has not been thoroughly examined.

Genetic Alterations and Risk Factors for Recurrence in Patients with Non-Small Cell Lung Cancer Who Underwent Complete Surgical Resection.

A definitive surgical resection is the preferred treatment for early-stage non-small cell lung cancer (NSCLC). Research on genetic alterations, including epidermal growth factor receptor (EGFR) mutations, in early-stage NSCLC remains insufficient. We investigated the prevalence of genetic alterations in early-stage NSCLC and the association between EGFR mutations and recurrence after a complete resection.

Major adverse cardiovascular events and hyperuricemia during tuberculosis treatment.

Background: Hyperuricemia is common during tuberculosis (TB) treatment, especially in association with pyrazinamide (PZA). This study investigated the relationship between major adverse cardiovascular events (MACEs) and hyperuricemia during TB treatment.

Methods: We conducted a single-center retrospective cohort study.

Effects of temperature, pH and sodium chloride on antimicrobial activity of magnesium oxide nanoparticles against E. coli O157:H7.

Aim: This study was done to determine the effects of temperature, pH and sodium chloride (NaCl) on antimicrobial activity of magnesium oxide (MgO) nanoparticles (NPs) against E. coli O157:H7.

Methods And Results: Culture conditions were established by varying the pH (5.

Development of Various Diabetes Prediction Models Using Machine Learning Techniques.

Background: There are many models for predicting diabetes mellitus (DM), but their clinical implication remains vague. Therefore, we aimed to create various DM prediction models using easily accessible health screening test parameters.

Methods: Two sets of variables were used to develop eight DM prediction models.

Necrotizing tracheobronchitis causing airway obstruction complicated by pandemic 2009 H1N1 influenza: A case report.

Rationale: Influenza is an infection caused by the influenza virus, and its symptoms are mostly mild and self-limiting. However, influenza can cause severe or fatal complications in high-risk patients. Although tracheobronchitis is one of the common complications of influenza, necrotizing tracheobronchitis is very rare.

Predictive factors for long-term responders of pemetrexed maintenance treatment in non-small cell lung cancer.

Background: We determined the clinical characteristics and predictive factors of long-term response to pemetrexed maintenance therapy as first-line treatment for non-small cell lung cancer (NSCLC).

Methods: A total of 950 advanced NSCLC patients received pemetrexed (500 mg/m ) plus cisplatin (60 mg/m ) (Pem-Cis) induction chemotherapy every three weeks as first-line treatment between January 2010 and August 2018. Patients who did not show progression after four cycles of Pem-Cis and received at least one cycle of pemetrexed maintenance were recruited (n = 199).
