A growing interest exists in identifying reliable and low-cost biomarkers or factors that could predict the therapeutic response, prognosis, recurrence, and survival in small-cell lung cancer (SCLC). Pralsetinib This study aimed to investigate the better predictors of chemotherapy efficacy and prognosis in patients with SCLC receiving first-line chemotherapy and radiotherapy.
This study retrospectively retrieved the medical records of patients with SCLC treated with first-line platinum-based chemotherapy and radiotherapy from January 2016 to June 2019 in the First Affiliated Hospital of Nanjing Medical University. Plasma biochemical parameters, clinical features, and overall survival (OS) time were collected. The independent effects of plasma parameters on patient survival were assessed by conducting univariate and multivariate Cox regression analyses. The optimal cut-off values of independent risk factors in the ROC curve and Kaplan-Meier survival analysis were determined using MedCalc software.
Statistically signer potential biomarker for predicting the clinical efficacy of chemotherapy and the prognosis of individuals with SCLC. Combining these two parameters could improve prediction efficacy.
Combined retreatment serum LDH and Fbg levels may be a better potential biomarker for predicting the clinical efficacy of chemotherapy and the prognosis of individuals with SCLC. Combining these two parameters could improve prediction efficacy.
Radiotherapy is one of the most common treatments for prostate cancer. Finding a useful predictor of the therapeutic outcome is crucial as it increases the efficacy of treatment planning. This study investigated the individual susceptibility to radiation based on chromosome 1 aberration frequency measured by the FISH (fluorescence in situ hybridization) method.
Whole blood samples were collected from 27 prostate cancer (PCa) patients and 32 subjects with benign prostatic hyperplasia (BPH), who were considered as a control group. Samples were irradiated with 2 Gy of x-rays, cultured, harvested, and used in the FISH procedure.
After irradiation, significantly higher levels of all studied chromosome 1 aberrations (except for deletions) in the group of PCa patients were revealed. Furthermore, in the lymphocytes of cancer patients, nearly five-fold higher frequencies of acentric fragments were observed compared to the BPH group. The highest individual radiosensitivities for all estimated biomarkers were seen in PCa patient cells who reported cancer incidence in the immediate family (CIF+).
The differences in chromosome 1 aberrations between PCa and BPH demonstrate that lymphocytes taken from patients with prostate cancer have higher radiosensitivity which might be related to hereditary or familiar inclinations. Therefore, this technique may find future application in searching biomarkers of the cellular radiotherapy response in prostate cancer patients.

There are scanty reports of the risk factors for pulmonary hypertensive crisis and low cardiac output syndrome after the operative repair of total anomalous pulmonary venous connection (TAPVC). We aim to evaluate early surgical outcomes of TAPVC and risk factors for pulmonary hypertensive crisis and low cardiac output syndrome.
We conducted a retrospective medical record review for all patients undergoing operative repair of TAPVC within 5 years. Outcome variables included pulmonary hypertensive crisis, low cardiac output syndrome and early mortality.
Of 58 patients, we documented 77.59% supracardiac, 20.69% cardiac and 1.72% mixed site of connection. About 86.21% patients underwent elective surgery, and 13.79% patients required emergency surgery. Incidence rates were 27.59% for pulmonary hypertensive crisis and 6.90% for low cardiac output syndrome. Body weight below 6 kg, pneumonia, tachycardia, hepatomegaly, preoperative pulmonary congestion on chest x-ray, preoperative elevated mean pulmonary artery pressure, preoperative pulmonary venous obstruction, emergency surgery and prolonged aortic cross-clamping time were significant risk factors for postoperative pulmonary hypertensive crisis. Significant risk factors for postoperative low cardiac output syndrome included pneumonia, prolonged duration of preoperative mechanical ventilation and prolonged aortic cross-clamping time.
The early outcome of surgical repair of TAPVC was acceptable, with 96.55% survival rate. This current analysis suggests that a thorough evaluation of all preoperative and operative characteristics is imperative to achieve best medical and surgical outcomes.

Gestational diabetes mellitus (GDM) induces cardiovascular and metabolic disturbances in offspring. However, the effects of GDM in pain processing in offspring and whether male and female offspring are equally affected is not well known. Thus, we determined i) whether GDM in mice affects offspring hindpaw mechanical sensitivity, capsaicin-induced spontaneous pain-like behaviors, and epidermal nerve fiber density (ENFD); and ii) whether there is sexual dimorphism in these parameters in offspring from GDM dams.
GDM was induced in pregnant ICR mice via i.p. streptozotocin (STZ). Then, glucose levels from dams and offspring were determined. Male and female offspring 2-3 months of age were evaluated for a) baseline mechanical sensitivity of the hind paw by using von Frey filaments; b) number of flinches and time spent guarding induced by intraplantar capsaicin (0.1%); and c) density of PGP-9.5 and CGRP axons in the epidermis from the hind paw glabrous skin.
Prepartum levels of glucose in STZ-treated dams were significantly increased compared to vehicle-treated dams; however, GDM or vehicle offspring displayed normal and similar blood glucose levels.
