Background: Platinum doublets are standard chemotherapy for advanced non-small-cell lung cancer (NSCLC). The aim of this study was to assess whether neutropenia is: (1) an indicator for treatment efficacy, or (2) associated with specific polymorphisms.
Patients And Methods: Four hundred ninety-four patients, treated with cisplatin-docetaxel were retrospectively analyzed. Relative dose intensity (RDI) was assessed for both drugs. Neutrophil counts were assessed only on Day 21 of each cycle. Genotyping was performed for 4 different polymorphisms in ERCC1, XRCC3, XPD-23, and XPD-10.
Results: The median overall survival was 9 months. The mean RDI was 0.94 for cisplatin and 0.93 for docetaxel. Four hundred three patients received ≥ 3 cycles of chemotherapy, and 239 received ≥ 6 cycles. Thirty-one percent developed neutropenia, and 19% had Grade (G)3-4 neutropenia. RDI was lower in patients with neutropenia (G1-4; 0.87-0.93) when compared with those without (G0; 0.94-0.95; P < .02). Male patients (P = .02) had inferior survival when compared with female patients, and ECOG (Eastern Cooperative Oncology Group) 1-2 patients (P < .001) had worse survival when compared with ECOG 0. There was no significant survival difference with respect to Grade of neutropenia (G0, 8.7 vs. G1-2, 11.6 vs. G3-4, 9.6 months; P = .41). In ECOG 0 patients, survival was significantly better for neutropenic G1-4 (hazard ratio [HR], 0.55; 95% confidence interval [CI], 0.31-0.96; P = .034) when compared with non-neutropenic (G0) patients. No association was observed between examined polymorphisms and neutropenia.
Conclusion: RDI was significantly higher in patients who did not develop neutropenia during treatment, but as the nadir period was not explored in our study, the low occurrence of neutropenia in our cohort is considered underestimated. There was no significant survival difference with respect to grade of neutropenia. Finally, none of the examined single nucleotide polymorphisms (SNPs) were associated with the presence of neutropenia, disease characteristics, response rates, or survival.

Background: Japanese encephalitis (JE) is a zoonotic parasitic disease caused by the Japanese encephalitis virus (JEV), and may cause fever, nausea, headache, or meningitis. It is currently unclear whether the epidemiological characteristics of the JEV have been affected by the extreme climatic conditions that have been observed in recent years.
Objective: This study aimed to examine the epidemiological characteristics, trends, and potential risk factors of JE in Taiwan from 2008 to 2020.

Background: Many tools have been developed to predict the risk of diabetes in a population without diabetes; however, these tools have shortcomings that include the omission of race, inclusion of variables that are not readily available to patients, and low sensitivity or specificity.
Objective: We aimed to develop and validate an easy, systematic index for predicting diabetes risk in the Asian population.
Methods: We collected the data from the NAGALA (NAfld [nonalcoholic fatty liver disease] in the Gifu Area, Longitudinal Analysis) database.

Objectives: This study compared cognitive flexibility (CF) and emotion recognition (ER) in adolescents with eating disorders (ED) to a healthy group.
Methods: Forty healthy individuals aged 12-18 years with no psychiatric diagnosis and 46 patients diagnosed with anorexia nervosa (AN), bulimia nervosa (BN), or binge eating disorder (BED) according to DSM-5 criteria participated. CF was assessed using the Cognitive Flexibility Scale (CFS), Stroop Test, and Berg Card Sorting Test (BCST), while ER was evaluated using the test of perception of affect via nonverbal cues.

Background: Clinical characteristics and outcomes of carbapenem-resistant Enterobacterales (CRE) infection and colonization have rarely been reported in patients with severe burns, who are prone to severe bacterial infections. This study aimed to evaluate clinical characteristics and outcomes of CRE infection and colonization in patients with severe burns.
Methods: The characteristics of 106 episodes of CRE acquisition (infection or colonization) in 98 patients with severe burns were evaluated by a retrospective medical record review.
