A new family of hybrid hyper-cross-linked thin films based on inorganic polyhedral oligomeric silsesquioxane (POSS) cages covalently bound with short organic imides has recently been developed using interfacial polycondensation followed by high-temperature imidization. These polyPOSS-imide networks were aimed at gas separations under harsh conditions, but the aliphatic arms of the initial POSS precursor, octa(aminopropyl)silsesquioxane, were found to be a weak link. This work investigates the replacement of the aliphatic arm by a phenyl derivative, octa(aminophenyl)silsesquioxane (OAPS). Although this new precursor is expected to be more thermoresistant, it introduces extra degrees of complexity since the functional -NH2 group on the phenyl ring can either be attached at a meta, a para or an ortho position. In order to avoid a costly programme of synthesis and testing, molecular dynamics (MD) simulations have been used to efficiently screen a large number of candidate structures based on mixtures of the three the networks based on either orthoOAPS and/or PMDA displayed superior resistance. TH5427 Nine polyOAPS-imides were further heated up to 400 °C, i.e. closer to the expected degradation, and re-submitted to isotropic dilations and uniaxial tensions. They confirmed the trends found at 300 °C with no signs of structural collapse. Using OAPS as the inorganic precursor thus significantly reinforces the thermoresistance of these hybrid hyper-cross-linked networks.

Prostate cancer (PCa) is the second most common malignancy in men. Radiotherapy and surgery successfully control organ-confined tumors, although, locally advanced/high-risk PCa frequently progress to the metastatic stage of the disease, which is uncurable. Identification of novel strategies to improve the efficacy of standard clinical protocols is a primary need. Among the molecular targets of potential clinical interest recently highlighted by accurate preclinical studies, the TRPM8 cation channel is particularly promising. In this study, we aim at establishing a standardized immunohistochemistry protocol to evaluate TRPM8 expression in normal and pathological prostate tissues.

The specificity and sensitivity of TRPM8 antibody ACC-049 was validated in different human prostate cell lines by western blot and immunocytochemistry analyses. Expression of the TRPM8 channel in normal and pathological prostate tissue was evaluated by immunohistochemistry using a tissue microarray containing 58 cases of prostate adenocarcinomas and in primary and lymph nodes metastatic human PCa matched specimens.

TRPM8 expression marks luminal epithelial cells in benign prostate tissue. In malignant lesions of the prostate, TRPM8 expression is frequently more abundant in advanced stages of the disease (PCa stage III/IV). Finally, lymph node metastases and matched primary tumors show similar amounts of the channel.

Collectively, our results reinforce the importance of TRPM8 as prostate biomarker and emphasize the value of the channel as promising novel molecular target for the treatment of prostate adenocarcinoma.

Reports suggest that preoperative optimization of a patient's serious comorbidities is associated with a reduction in postoperative complications.

The purpose of this study was to assess the cost and benefits of preoperative optimization, accounting for total costs associated with postoperative morbidity.

This study is a decision tree cost-effectiveness analysis with probabilistic sensitivity analysis (10,000 iterations).

This is a hypothetical scenario of stage II colon cancer surgery.

The simulated 65-year-old patient has left-sided, stage II colon cancer.

Focused preoperative optimization targets high-risk comorbidities.

Total discounted (3%) economic costs (US $2018), effectiveness (quality-adjusted life-years), incremental cost-effectiveness ratio (incremental cost-effectiveness ratio, cost/quality-adjusted life-years gained), and net monetary benefit.

We calculated the per individual expected health care sector total cost of preoperative optimization and sequelae to be $12,395 versus $15del paciente.CONCLUSIONESSi bien actualmente no se reembolsa de manera integral, la optimización preoperatoria enfocada puede reducir los costos totales de la atención y al mismo tiempo reducir las complicaciones de la cirugía de cáncer de colon.

The current opioid crisis has motivated surgeons to critically evaluate ways to balance postoperative pain while decreasing opioid use and thereby reducing opioids available for community diversion. The longest incision for robotic colorectal surgery is the specimen extraction site incision. Intracorporeal techniques allow specimen extraction to be at any location.

This study was designed to determine whether the Pfannenstiel location is associated with less pain and opioid use than other abdominal wall specimen extraction sites.

This was a retrospective cohort study.

The study was conducted with a prospectively maintained colorectal surgery database (July 2018 through October 2019).

Patients with enhanced recovery robotic colorectal resections with specimen extraction were included.

Propensity score weighting was used to derive adjusted rates for numeric pain scores, inpatient opioid use, opioids prescribed at discharge, opioid refills after discharge, and other related outcomes. For comparing ou% frente a 98,45%, p = 0,006). Las complicaciones postoperatorias y los reingresos, no fueron diferentes entre los grupos.LIMITACIONESUna sola institución.CONCLUSIÓNLa incisión de Pfannenstiel como sitio de extracción de la muestra en cirugía mínimamente invasiva, se asocia con dolor postoperatorio y uso de opioides similar, a otros sitios de extracción en pacientes sometidos a resecciones robóticas colorrectales. Sitios de extracción de la muestra, pueden elegirse en función de factores del paciente distintos al dolor y uso de opioides. Consulte Video Resumen en http//links.lww.com/DCR/B495.).
