Rapid Breast Cancer Disease Progression Following Cyclin Dependent Kinase 4 and 6 Inhibitor Discontinuation.

Background: CDK 4 and 6 inhibitors (CDK4/6i), which arrest unregulated cancer cell proliferation, show clinical efficacy in breast cancer. Unexpectedly, a patient treated on a CDK4/6i-based trial, as first-line therapy in metastatic breast cancer, developed rapid disease progression following discontinuation of study drug while receiving standard second-line therapy off trial. We thus sought to expand this observation within a population of patients treated similarly at The University of Texas MD Anderson Cancer Center. Methods: Using an IRB-approved protocol, 4 patients previously enrolled on CDK4/6i trials were analyzed for outcomes after discontinuing study drug. These patients were treated on a randomized trial of first-line endocrine therapy +/- a CDK4/6i. Rapid disease progression was defined as progression occurring within 4 months of CDK4/6i discontinuation. Results: In total, 4 patients developed rapid disease progression and died; 2 of whom died within 6 months of CDK4/6i discontinuation. Conclusion: This case series suggests a potential for rapid disease progression following CDK4/6i discontinuation. However, the clinical course following progression must be validated in large CDK4/6i clinical trials and standard-of-care cohorts. If confirmed, such observations may alter the algorithm for subsequent therapy in patients with disease progression on CDK4/6i. Nevertheless, the need remains to define a mechanistic basis for this rapid progression and formulate alternative therapeutic strategies

The analysis of facial beauty: an emerging area of research in pattern analysis

Much research presented recently supports the idea that the human perception of attractiveness is data-driven and largely irrespective of the perceiver. This suggests using pattern analysis techniques for beauty analysis. Several scientific papers on this subject are appearing in image processing, computer vision and pattern analysis contexts, or use techniques of these areas. In this paper, we will survey the recent studies on automatic analysis of facial beauty, and discuss research lines and practical application

Isolation of Peroxidase Isozymes from Two Flax Genotypes by Column Chromatography

Isolation of the four major peroxidase isozymes (isozymes 1, 2, 3, and 4) of two flax genotypes was achieved by modifying the procedure used by Shannon et al. (1966) for the isolation of horseradish peroxidase isozymes. The net positive and net negative charges of isozymes 1, 2, and 4 were different. Isozyme 3 resembled isozyme 4 in charge but differed in apparent molecular weight. The chromatographic elution profiles of both genotypes were the same. Anionic gel electrophoresis demonstrated that after isolation and repurification, relative mobility differences existed between the corresponding isozymes of the two genotypes for all four isozymes

A mixed methods analysis of factors affecting antenatal care content: A Syrian case study

Background Maternity care services provide critical interventions aimed at improving maternal and newborn health. In this study, we examined determinants of antenatal care (ANC) content in Syria, together with changes over time. Methods We analysed two national surveys conducted by the Central Bureau of Statistics in Damascus (PAPFAM 2001 and MICS 2006). Findings of this initial analysis led to a qualitative study on adequacy of antenatal care content in two Syrian governorates, Aleppo and Latakia in 2010, which in turn informed further quantitative analysis. The perspectives and practices of doctors, women, midwives and health officials were explored using in-depth interviews. A framework approach was used to analyse the data. Results The quantitative analysis demonstrated that women’s education level, the type of health facility they attended and whether they had experienced health complications were important determinants of adequacy of ANC content received. The qualitative study revealed that additional factors related to supply side and demand side factors (e.g. organization of health services, doctors’ selective prescription of ANC tests and women’s selective uptake of those tests), influenced the quality of ANC and explained some regional differences between Aleppo and Latakia. Conclusions The percentage of women who received adequate ANC content was probably higher in Latakia than in Aleppo because women in Latakia were more educated, and because services were more available, accessible, and acceptable to them

Proportions of the aesthetic African-Caribbean face : idealized ratios, comparison with the golden proportion and perceptions of attractiveness

Abstract Background In the absence of clear guidelines for facial aesthetic surgery, most surgeons rely on expert intuitive judgement when planning aesthetic and reconstructive surgery. One of the most famous theories regarding “ideal” facial proportions is that of the golden proportion. However, there are conflicting opinions as to whether it can be used to assess facial attractiveness. The aim of this investigation was to assess facial ratios of professional black models and to compare the ratios with the golden proportion. Methods Forty photographs of male and female professional black models were collected. Observers were asked to assign a score from 1 to 10 (1 = not very attractive, 10 = very attractive). A total of 287 responses were analysed for grading behaviour according to various demographic factors by two groups of observers. The best graded photographs were compared with the least well-graded photographs to identify any differences in their facial ratios. The models’ facial ratios were calculated and compared with the golden proportion. Results Differences in grading behaviour were observed amongst the two assessment groups. Only one out of the 12 facial ratios was not significantly different from the golden proportion. Conclusions Only one facial ratio was observed to be similar to the golden proportion in professional model facial photographs. No correlation was found between facial ratios in professional black models with the golden proportion. It is proposed that an individualistic treatment for each ratio is a rather better method to guide future practice

Childbirth Experiences and Delivery Care During Times of War: Testimonies of Syrian Women and Doctors

Background: Until the eruption of violence in 2011, Syria made good progress in improving maternal health indicators including reducing the maternal mortality ratio and increasing the level of skilled birth attendance. The war in Syria has been described as one of the worst humanitarian crises in recent times. Damascus Maternity Teaching Hospital is the largest maternity public hospital in the country that survived the war and continued to provide its services even during periods of pronounced instability. The main aim of this paper is to highlight the experience of childbirth and delivery care as described by women and doctors at times of severe violence affecting Damascus. Methods: This paper is based on secondary analysis of qualitative data collected between 2012 and 2014 for a WHO-funded implementation research project introducing clinical audits for maternal near-misses. This analysis specifically looked at the effects of violence on the childbirth experience and delivery care from the perspective of both women and physicians. A total of 13 in-depth interviews with women who had recently delivered and survived a complication and 13 in-depth interviews with consultant obstetricians were reviewed and analyzed, in addition to three focus group discussions with 31 junior care providers. Results: Three themes emerged concerning the experiences of women and doctors in these times of war. First, both women and doctors experienced difficulty reaching the hospital and accessing and providing the services, respectively; second, quality of care was challenged at that time as perceived by both women and doctors; and third, women and doctors expressed their psychological suffering in times of hardship and uncertainty and how this affected them. Conclusions: Efforts to safeguard the safety of delivery and prevent maternal mortality in Syria continued despite very violent and stressful conditions. Both women and providers developed strategies to navigate the challenges posed by conflict to the provision of delivery care. Lessons learned from the experiences of both women and doctors should be considered in any plans to improve maternal healthcare in a country like Syria that remains committed to achieving the Sustainable Development Goals in 2030 in the aftermath of nearly 10 years of war.

<p>Abstract</p> <p>Introduction</p> <p>The causes of diffuse abdominal pain following pelvic surgery are numerous. We present a rare case of acute abdominal pain in a woman in the post-partum period.</p> <p>Case presentation</p> <p>A 25-year-old Caucasian woman with neurofibromatosis type 1 presented to our hospital with diffuse abdominal pain immediately after a cesarean section. The patient was acutely ill and toxic with a fever of 38.8°C, a pulse of 120 beats per minute and a distended abdomen with absent bowel sounds. A computed tomography scan showed air in the wall of the stomach and portal venous system. The patient was successfully treated with intravenous antibiotics, bowel rest and total parenteral nutrition.</p> <p>Conclusion</p> <p>It is rare for a case of emphysematous gastritis associated with portal venous air to be treated successfully without surgery. To the best of our knowledge, to date there has been no reported association of emphysematous gastritis with neurofibromatosis.</p

Patient attitudes towards medical students at Damascus University teaching hospitals

Background: The cooperation of patients and their consent to involve medical students in their care is vital to clinical education, but large numbers of students and lack of experience as well as loss of privacy may evoke negative attitudes of patients, which may sometimes adversely affect the clinical teaching environment. This study aimed to explore the attitudes of patients towards medical students at Damascus University hospitals, and to explore the determinants of those attitudes thus discussing possible implications applicable to clinical teaching. Methods: This cross-sectional study was conducted at three teaching hospitals affiliated to the Faculty of Medicine at Damascus University. Four hundred patients were interviewed between March and April 2011 by a trained sociologist using a structured questionnaire. Results: Of the patients interviewed, 67.8 % approved the presence of medical students during the medical consultation and 58.2 % of them felt comfortable with the presence of students, especially among patients with better socio-economic characteristics. 81.5 % of the patients agreed to be examined by students in the presence of the supervisor, while 40.2 % gave agreement even in the absence of the supervisor. Privacy was the most important factor in the patients ’ reticence towards examination by the students, whilst the relative safety and comfort if a supervisor was available determined patients ’ agreement
