Aim: We evaluated the pharmacokinetics and quality of life of elderly patients with advanced non-small-cell lung cancer (NSCLC) treated with bi-weekly carboplatin and paclitaxel chemotherapy, and determined the maximum tolerated dose (MTD) of this treatment.
Patients And Methods: Eligible patients had histologically- or cytologically-proven inoperable NSCLC, age of 70 years or older, no prior treatment, and Eastern Cooperative Oncology Group performance status 0-2. Paclitaxel was administered in combination with carboplatin under a bi-weekly schedule. We determined the plasma concentrations of both drugs during therapy.
Results: The median patient age was 80 years. Using carboplatin at AUC 3, the MTD of paclitaxel was 100 mg/m(2). Both hematological and non-hematological toxicities were mostly mild and manageable. Although paclitaxel is predominantly metabolized in the liver, clearance was decreased in patients with lower estimated glomerular filtration rate.
Conclusion: Bi-weekly treatment, as described here, is feasible for elderly patients as a conventional regimen, particularly in the outpatient setting, due to its lower toxicity.

Background: Depression constitutes a risk factor for osteoporosis, but underlying molecular and cellular mechanisms are not fully understood. MiRNAs influence gene expression and are carried by extracellular vesicles (EV), affecting cell-cell communication.
Aims: (1) Identify the difference in miRNA expression between depressed patients and healthy controls; (2) Analyze associations of these miRNAs with bone turnover markers; (3) Analyze target genes of differentially regulated miRNAs and predict associated pathways regarding depression and bone metabolism.
Association of Circulating Basophil Count with Gastric Cancer Prognosis.

Purpose: Basophils play a crucial role in immunoglobulin E-mediated allergic reactions and parasitic infections. Recently, a low basophil count was reported to be a poor prognostic indicator in patients with malignant tumors. This study aimed to investigate the cut-off value to evaluate the clinicopathological and prognostic significance of the basophil count in patients with gastric cancer.

The aim of this study was to compare the effectiveness of different types of low level laser treatment (LLLT) in reducing pain levels, changing oxygen saturation and bite force in patients with myofacial pain syndrome (MPS). 45 patients were randomly assigned to three groups: Group 1 (GRR laser, n = 15) received LLLT with Gallium-Aluminium-Arsenide (GaAlAs) diode laser with a wavelength of 904 nm and red laser with a wavelength of 650 nm over masseter muscle region. Group 2 (Nd: YAG laser, n = 15) were treated with Neodymium-doped Yttrium Aluminium Garnet laser with a wavelength of 1064 nm and the same protocol with Nd: YAG laser was performed in the Group 3 (placebo, n = 15) using sham device.
