Low-dose, weekly cisplatin (40 mg/m
  ) regimens are currently utilized at Eskenazi Health in Indianapolis, Indiana for the treatment of head and neck cancer due to enhanced tolerability. This retrospective analysis analyzes the incidence, severity, and risk factors for AKI in patients who received this regimen.
 
  A retrospective chart review was conducted including patients with head and neck cancer treated with weekly, low dose cisplatin (40 mg/m
  ) with concurrent radiotherapy (RT). From this criteria, 22 patients were identified and included in the final analysis. AKI was defined by the Common Terminology Criteria for Adverse Events (CTCAE) version 4.03.
 
  Of the 22 patients included, 12 (54.5%) experienced AKI, with 10 patients (45.5%) experiencing grade 1 AKI and 2 patients (9.1%) experiencing grade 2 AKI. Six patients (27.3%) required dose adjustments or delays due to renal adverse events, all of which had initial cisplatin total weekly doses of >70 mg.  https://www.selleckchem.com/products/ag-221-enasidenib.html  Those receiving a total weekly cisplatin dose of >70 mg were found to have a higher risk of developing an episode of AKI compared to the group receiving <70 mg (p = 0.029).
 
  This analysis showed patients receiving weekly doses >70 mg of cisplatin as their initial treatment dose for head and neck cancer were more likely to experience AKI. There are inconsistencies in the frequency of AKI in our study compared to published literature; however, this comparison is difficult due to the small sample size of our trial. This demonstrates the need for further investigation into the issue.

  This study aimed to investigate the parameters with a significant impact on delivery quality assurance (DQA) failure and analyze the planning parameters as possible predictors of DQA failure for helical tomotherapy.
 
  In total, 212 patients who passed or failed DQA measurements were retrospectively included in this study. Brain (n = 43), head and neck (n = 37), spinal (n = 12), prostate (n = 36), rectal (n = 36), pelvis (n = 13), cranial spinal irradiation and a treatment field including lymph nodes (n = 24), and other types of cancer (n = 11) were selected. The correlation between DQA results and treatment planning parameters were analyzed using logistic regression analysis. Receiver operating characteristic (ROC) curves, areas under the curves (AUCs), and the Classification and Regression Tree (CART) algorithm were used to analyze treatment planning parameters as possible predictors for DQA failure.
 
  The AUC for leaf open time (LOT) was 0.70, and its cut-off point was approximately 30%. The ROC curve for the predicted probability calculated when the multivariate variable model was applied showed an AUC of 0.815. We confirmed that total monitor units, total dose, and LOT were significant predictors for DQA failure using the CART.
 
  The probability of DQA failure was higher when the percentage of LOT below 100 ms was higher than 30%. The percentage of LOT below 100 ms should be considered in the treatment planning process. The findings from this study may assist in the prediction of DQA failure in the future.

This study assessed the association between internalized homophobia and sexual risk behavior among HIV-infected MSM and the mediating effects of safe-sex self-efficacy and depression on this association, using a theoretical framework based on the Theory of Social Action. Data were collected from 124 HIV-infected MSM attending an AIDS clinic in Israel. No significant association was found between internalized homophobia and sexual risk behavior (unprotected anal intercourse). Examination of mediation effects revealed full mediation by depression, but not by self-efficacy. Depression and self-efficacy were the only significant explanatory variables of sexual risk behavior. Diverse social work interventions with HIV-infected MSM aimed at reducing sexual risk behaviors should include routine screening of IH and its association with depression, and address depression and self-efficacy in CBT and other interventions.This study aimed to explore the influences of microRNA-195 (miRNA-195)/Rap2C/MAPK in the proliferation and apoptosis of small cell lung cancer (SCLC) cells. QRT-PCR analysis were executed to evaluate miRNA-195 expression in lung cancer tissues and SCLC cells, and the western blot was implemented to monitor Rap2C protein level and uncovered whether the MAPK signaling pathway in lung cancer tissues and SCLC cells was activated. The CCK-8 experiment was performed to detect cell proliferation ability, and the flow cytometry was utilized to examine cell apoptosis level. Luciferase reporter gene system was executed to disclose the interaction between miRNA-195 and Rap2C. Subcutaneous implantation mouse models of SCLC cells were constructed to detect cell proliferation in vivo, and Kaplan-Meier method calculated patient survival. The expression of Rap2C was higher in lung cancer tissues and SCLC cells than in normal tissues and cells, while the expression of miRNA-195 was lower in lung cancer tissues and SCLC cells than in normal tissues and cells. miRNA-195 lower expression predicted showed reduced overall survival in lung cancer patients. Further loss of function and enhancement experiments revealed that miRNA-195 overexpression could significantly inhibit SCLC cell proliferation and promote cell apoptosis by upregulation of Bax and down-regulation of bcl-2; Luciferase reporter assay demonstrated that miRNA-195 could bind to Rap2C mRNA and inhibit its expression, Rap2C overexpression also related to the poorer prognosis of lung patients. Knockdown of Rap2C suppressed cell proliferation and expedited apoptosis. In addition, overexpression of Rap2C reversed miRNA-195-induced apoptosis and proliferation inhibition. Furthermore, miRNA195 prohibited the activation of MAPK signaling pathway by down-regulating Rap2C. These consequences indicated that miRNA-195 promotes the apoptosis and inhibits the proliferation of small cell lung cancer (SCLC) cells via inhibiting Rap2C protein-dependent MAPK signal transduction.
