Mitotane is the only adrenolytic drug approved by the Food and Drug Administration for treating adrenocortical carcinoma (ACC). This drug has cytotoxic effects on tumour tissues; it induces cell death and antisecretory effects on adrenal cells by inhibiting the synthesis of adrenocortical steroids, which are involved in the pathogenesis of ACC. However, high doses of mitotane are usually necessary to reach the therapeutic plasma concentration, which may result in several adverse effects. This suggests that important pharmacological processes, such as first pass metabolism, tissue accumulation and extensive time for drug elimination, are associated with mitotane administration. Few studies have reported the pharmacological aspects and therapeutic effects of mitotane. Therefore, the aim of this review was to summarize the chemistry, pharmacokinetics and pharmacodynamics, and therapeutic and toxic effects of mitotane. This review also discusses new perspectives of mitotane formulation that are currently under investigation. Understanding the pharmacological profile of mitotane can improve the monitoring and efficacy of this drug in ACC treatment and can provide useful information for the development of new drugs with specific action against ACC with fewer adverse effects.
Accumulating evidence suggests that the prevalence of eating disorders among Chinese women is a public health concern. Prior studies have drawn linkages between conflicting cultural values, identity confusion, and eating disorder symptomatology, which may be relevant for understanding the rise of eating disorders amidst China's rapid economic and sociocultural transformation. Here, we explore how women's experiences with traditional eating norms and modernizing norms of femininity may shape their food and body attitudes.

Chinese young adult women (N = 34; aged 18-22 years) participated in semi-structured interviews focusing on experiences with norms surrounding eating and ideal feminine appearance, perceived conflict between these norms, and their responses to perceived conflict. Interviews were conducted via email (n = 27) or via Skype (n = 7). Participants were not asked about past or present diagnoses of eating disorders. Analysis of responses was guided by the principles of thematic analysis.

Women ts balance interpersonal and individual needs.Masquelet's induced membrane technique (MIMT) is a relatively new, two-stage surgical procedure to reconstruct segmental bone defects. First performed by Dr. Masquelet in the mid-1980s, MIMT has shown great promise to revolutionize critical-sized bone defect repair and has several advantages over its alternative, distraction osteogenesis (DO). Also, its success in extremely challenging cases (defects > 15 cm) suggests that its study could lead to discovery of novel biological mechanisms that might be at play during segmental defect healing and fracture non-union. MIMT's advantages over DO have led to a world-wide increase in MIMT procedures over the past decades. However, MIMT often needs to be repeated and so the average initial success rate in adults lags significantly behind that of DO (86% vs 95%, respectively). The autologous foreign-body membrane created during the first stage by the immune system's response to a polymethyl methacrylate bone cement spacer is critical to supporting the morselized bone graft implanted in the second stage. However, the biological and/or physical mechanisms by which the membrane supports graft to bone union are unclear. This lack of knowledge makes refining MIMT and improving the success rates through technique improvements and patient selection a significant challenge and hinders wider adoption. In this review, current knowledge from basic, translational, and clinical studies is summarized. The dynamics of both stages under normal conditions as well as with drug or material perturbations is discussed along with perspectives on high-priority future research directions.
During vocal fold vibration, the medial surface of both folds forms a convergent shape during opening and a divergent shape during closing. A greater maximum divergence angle is associated with greater closing forces which will increase the closing speed of the glottis. An increased closing speed results in a greater acoustic intensity and greater vocal efficiency. Indentation testing showed that as the strain increases, the inferior aspect of the folds becomes stiffer than the superior aspect, resulting in the vertical stiffness gradient (VSG). We hypothesize that a reduction of the vertical stiffness gradient will reduce the maximum divergence angle.

Four excised canine larynges were tested. Stress-strain curves of the superior and inferior aspects of the fold in the mid membranous plane of the baseline larynges were taken using the indentation method. Calcium hydroxylapatite (CaHA) crystals were then injected into the superior aspect of the fold. The stress-strain tests were repeated. Particle imaging velocimetry (PIV) of the intraglottal velocity fields was performed in three larynges at different subglottal pressures in the mid coronal plane for the baseline and CaHA-injected larynges.

CaHA injection reduced the inferior-superior stiffness gradient in all larynges. The maximal divergence angle was markedly reduced. In some cases, there was not a divergent angle.

Marked reduction of the vertical stiffness gradient significantly reduces the maximum divergence angle. Clinical implications will be discussed.

To determine the rate and predictors of receiving multiple tympanostomy tube (TT) placements in children.

Systematic review and meta-analysis.

PubMed, EMBASE, and Cochrane Library databases were searched for studies reporting the risk factors for receiving repeat TT (r-TT) placements in children with chronic otitis media with effusion or recurrent acute otitis media. Opaganib in vivo These articles were systematically reviewed in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) recommendations. Data were pooled using a random-effects model.

Twenty-one studies involving a total of 290,897 children were included. Among all patients, 24.1% (95% confidence interval (CI), 18.2%-29.9%) underwent ≥2 TT placements and 7.5% (95% CI, 5.7%-9.4%) underwent ≥3 TT placements. Craniofacial disease (odds ratio (OR) 5.13, 95% CI, 1.57-16.74) was the strongest predictor of r-TT. Younger age at initial TT placement and shorter TT retention time were also significantly associated with r-TT. Receipt of primary adenoidectomy with initial TT placement was associated with decreased odds of r-TT (OR, 0.
