Background: Prostate cancer is the most commonly diagnosed malignancy in the UK. Castrate resistant prostate cancer (CRPC) can be difficult to manage with response to next generation hormonal treatment variable. AR-V7 is a protein biomarker that can be used to predict response to treatment and potentially better inform management in these patients.

This paper reviews some of the common challenges to high-quality decision-making at the leadership level, such as limiting decision shortcuts, analytical blind spots, failure to consider multiple perspectives or options, and reluctance to adjust decisions that are not working well. The paper also reviews some of the pertinent literature and scholarship on decision-making approaches to build a summative decision-making model of anticipatory foresight and adaptation to overcome dysfunctional decision-making mistakes. The paper proposes a new framework that focuses on the internal decision-making processes that leaders should adopt - an approach to decision-making that combines the concepts of anticipatory foresight, predictive vision, creative imagination, adaptive skill sets and adaptive flexibility.

Background: Gracilis flap reconstruction (GFR) following abdominoperineal resection (APR) or proctocolectomy (PC) can reduce pelvic wound complications but has not been adequately assessed in the setting of immunosuppression, fistulous disease, and neoadjuvant chemoradiation.

Methods: Patients undergoing APR/PC with GFR were retrospectively analyzed with regard to perioperative characteristics, and morbidity was assessed.

Results: Patients underwent GFR for rectal cancer ( = 28), anal cancer ( = 3), inflammatory bowel disease ( = 13), or benign fistulizing disease ( = 1).

Article Synopsis
  • - Platinum-based treatments have not been shown to improve survival rates in advanced prostate cancer (PCa) patients despite their potential.
  • - Some prostate cancers have specific DNA repair defects, known as homologous recombination DNA (HRD) defects, which respond well to treatments that include poly(ADP)-ribose polymerase inhibition and platinum drugs.
  • - A report details three advanced castration-resistant PCa patients with HRD defects who had remarkable responses to treatment with carboplatin.

Previous research indicates that autistic individuals are more likely to be bullied, and that they experience heightened anxiety and diminished self-esteem. These factors are known to predict heightened compliance, which is the tendency to agree with or carry out the requests and demands of others. This has a range of potentially serious consequences, particularly for an autistic person.

Purpose Of Review: Poly (ADP-ribose) polymerase inhibitors (PARPi) are approved drugs for the treatment of ovarian and breast cancer and currently under investigation for the treatment of prostate cancer and other malignancies with aberrations in homologous recombination DNA repair.This review summarizes literature published during 2017 concerning the relevance of PARPi in prostate cancer and presents new evidence on mechanisms of resistance and biomarkers of response.

Recent Findings: The approval of several PARPi (olaparib, rucaparib, and niraparib) has driven the focus of anticancer treatment on synthetic lethality in prostate cancer too.

Background: The use of mesh during ventral hernia repair (VHR) is a well-accepted concept. However, the ideal location of mesh placement remains strongly debated. Although VHR with onlay mesh placement has historically been associated with a high rate of wound events, this surgical approach is technically less challenging than VHR with sublay mesh placement.

Background: Immediate postmastectomy breast reconstruction in morbidly obese patients represents a challenge because neither prosthetic nor abdominal-based options may be suitable.

Methods: This study compared a previously published cohort of immediate prosthetic reconstruction of 346 patients (511 breasts) of whom 49 patients (67 breasts) were morbidly obese (defined as a body mass index > 35) with a morbidly obese patient population whose breasts were reconstructed immediately following postmastectomy with latissimus flap and tissue expander (21 patients and 22 breasts) in the same time period. The preoperative risk factors of mastectomy such as tobacco use, diabetes, and prior radiation and the postoperative complications of mastectomy such as skin necrosis, seroma, and prosthesis loss were examined.

Background: Human acellular dermis has been adopted for routine use in tissue expander reconstruction. The purported benefits include higher intraoperative fill volume, facilitation of lower pole expansion, and enhanced definition of the lower pole of the breast. Recently, concerns have arisen about an increase in postoperative complications with its use.

One significant human rights violation in Southeast Asia is the exploitation of women through sex tourism. Such sexual exploitation occurs in Thailand because institutions are complacent and society accepts the practice. This case study, guided by the concepts of double binds and hegemonic masculinity, sought to understand if Thai culture is symbolically constructed in ways to portray Thailand as a desirable "sex tourist" destination.

Endothelial-monocyte interactions are regulated by adhesion molecules and key in the development of vascular inflammatory disease. Peroxisome proliferator-activated receptor (PPAR) γ activation in endothelial cells is recognized to mediate anti-inflammatory effects that inhibit monocyte rolling and adhesion. Herein, evidence is provided for a novel mechanism for the anti-inflammatory effects of PPARγ ligand action that involves inhibition of proinflammatory cytokine-dependent up-regulation of endothelial N-glycans.

The mechanisms by which isoflavones protect against inflammatory vascular disease remain unclear. Our previous observations suggest that one mechanism involves inhibition of monocyte-endothelial cell interactions in a process that is absolutely dependent on flow. The molecular mechanisms involved and the effects of structurally distinct isoflavones on this process are not known and are investigated herein.

A prospective study was conducted to determine the efficacy of using recombinant BMP-7 (rhOP-1) as an adjuvant in the treatment of diaphyseal humeral nonunions. Twenty-three consecutive patients with atrophic humeral diaphyseal nonunions were treated at seven separate institutions. All nonunions were fixed with either a compression plate or an intramedullary nail in conjunction with various bone grafting techniques.

In polarized cells, such as neurons, ankyrin-type proteins are the major molecules that link the actin-spectrin-based membrane cytoskeleton to the plasma membrane. In Drosophila the second ankyrin gene, Dank2, is exclusively expressed in neuronal cells. Similar to ankyrin genes in other organisms, the Dank2 gene generates several ankyrin protein isoforms by differential splicing.
