Attrition in surgical residency programmes: Causes and effects
Objective: To determine the rate and trend of attrition from a surgical residency programme and to identify the reasons for attrition.Methods: A questionnaire-based survey was conducted at a university hospital. Separate questionnaires were designed for residents and programme directors (PDs). The residents who left the training voluntarily from one of the five surgical residency programmes (i.e., general surgery, orthopaedics, neurosurgery, otorhinolaryngology and urology) during the academic years 2005-2011 were identified from a departmental database. The residents who did not respond after three attempts at contact, or those who refused to participate, were excluded.Results: During the last 6years, 106 residents were recruited; 84 (78%) were men, of whom 34.5% left the programme voluntarily. Of 22 women, half (54%) left the programme voluntarily (P=0.07). The overall 6-year attrition rate was 39%. The reasons identified for attrition, in descending order, were personal reasons, attitude of senior residents or faculty, and change of specialty. None of the residents cited an excess workload as a reason for their leaving the programme. About 40% rejoined the same specialty after leaving, while 35% chose a different specialty (80% chose a different surgical subspecialty and 20% chose medicine). There was a significant discrepancy in the perspective of residents and PDs about the reasons for attrition.Conclusion: Attrition among surgical residents, in particular woman residents, is high. Personal reasons and interpersonal relations were the most commonly cited reasons. Programme managers and residents have significantly different perspectives, again an indication of a communication gap
Insight into the molecular pathophysiology of myelodysplastic syndromes: targets for novel therapy
Myelodysplastic syndromes (MDS) are clonal hematopoietic stem cell disorders characterized by abnormal cellular differentiation and maturation with variable progression to acute leukemia. Over the last decade, scientific discoveries have unraveled specific pathways involved in the complex pathophysiology of MDS. Prominent examples include aberrations in cytokines and their signaling pathways (such as tumor necrosis factor-alpha, interferon-gamma, SMAD proteins), mutations in genes encoding the RNA splicing machinery (SF3B1, SRSF2, ZRSR2, and U2AF1 genes), mutations in genes disrupting the epigenetic machinery (TET2, DNMT3A, DNMT3B, EZH2, ASXL1). In addition, abnormalities in regulatory T-cell dynamics and atypical interactions between the bone marrow microenvironment, stroma and progenitor cells, and abnormal maintenance of telomeres are also notable contributors to the complex pathogenesis of MDS. These pathways represent potential targets for novel therapies. Specific therapies include drugs targeting aberrant DNA methylation and chromatin remodeling, modulating/activating the immune system to enhance tumor-specific cellular immune responses and reduce anomalous cytokine signaling, and blocking abnormal interaction between hematopoietic progenitors and stromal cells
Role of early contrast enhanced CT scan in severity prediction of acute pancreatitis
Abstract
Severe pancreatitis occurs in approximately 15-25% of patients with acute pancreatitis. The objective of our study was to compare the CTSeverity Index (CTSI) with a clinical score (BISAP score) to predict severity of acute pancreatitis. Forty-eight consecutive patients with acutepancreatitis who underwent contrast enhanced CT scan within 72 hours of presentation were included. Results of our study showed that both CTSI and BISAP score were reliable predictors of mortality (p value = 0.019 and \u3c0.001 respectively) and need for mechanical ventilation (p value = .002 and .006 respectively). Positive predictive value of CTSI to predict recovery without intervention was 91.4% as compared to 78% for that of BISAP score. Receiver Operating Characteristics (ROC) Curves showed CT scan was superior to BISAP Score in predicting need of percutaneous or surgical intervention. Early CT scan may be utilized for prediction of clinical course of patients with acute pancreatitis
A Review of Eviction Protections in Dallas, Texas
The Institute for Urban Policy Research partnered with the Texas Tenants Union to better understand the impact of eviction remediation programs on the plight of tenants in the City of Dallas. In Dallas, roughly three of every five households rent their home; programs aimed at preventing eviction are pertinent to most of Dallas's population (U. S. Census Bureau, 2020). Financial impacts of the Coronavirus pandemic threatened many households in Dallas and the early days of the pandemic saw multiple policy and procedure interventions, including court closures and the CARES Act. Dallas City Council was among the first localities to act, pass an eviction ordinance to protect renters from losing their homes.In this study, we pursue a mixed-methods approach, embracing both qualitative and quantitative research tools. Working with Dallas County, whose Justice of the Peace courts are the courts of original jurisdictions for evictions in Texas, we secured case filing data for January through June of 2019 and 2020. This data was used to perform a series of regression analyses comparing the volume of evictions in Dallas and surrounding cities. Next, we randomly sampled cases filed in one Dallas County Justice of the Peace court, including portions of Dallas and surrounding communities. We conducted a systematic record review of the entire case file for each of the randomly sampled cases. Finally, we engaged a purposive sample of local government and non-profit leaders, as well as affected tenants, in a focus group setting to understand their experiences with eviction in Dallas.While the quantitative results do suggest some impact of these policy responses, the findings are not encouraging. First, the milieu of policies enacted offered no universal protection to any broad segment of renting households. Second, many of those protected by these policies did not know their status, and efforts to educate them were not universally deployed. Finally, even when protected tenants were aware of their protection, their attempts to assert their rights were met by a system often confused on how to respect them
Venous thromboembolism following hematopoietic stem cell transplantation-a systematic review and meta-analysis
Venous thromboembolism (VTE) is a common complication of hematopoietic stem cell transplantation (HSCT). Graft-versus-host disease (GVHD) is another complication of HSCT that may modify the risk of VTE. Our objective was to explore the incidence of VTE (deep venous thrombosis and pulmonary embolism) following HSCT and to evaluate its association with GVHD. A comprehensive search of Medline In-Process & Other Non-Indexed Citations, MEDLINE, EMBASE, Cochrane Central Register of Controlled Trials, and Scopus was conducted to search for both retrospective and prospective HSCT studies which had reported VTE. Random-effects meta-analysis was used to pool incidence rates. We included 17 studies reporting on allogeneic- and 10 on autologous-HSCT; enrolling 6693 patients; of which 5 were randomized. The overall incidence of VTE after HSCT was 5%(4-7%). Incidence in allogeneic-HSCT was 4%(2-6%) and in autologous-HSCT was 4%(1-15%). Eleven and nine studies reported data on acute and chronic GVHD, respectively. The incidence of VTE in chronic GVHD was 35%(20-54%), whereas in acute GVHD it was 47%(32-62%). Based on the results of this meta-analysis, VTE is a fairly common complication after HSCT, emphasizing the importance of assimilating guidelines for both treatment and prophylaxis in this patient population

Antimicrobial resistance among migrants in Europe: a systematic review and meta-analysis
BACKGROUND: Rates of antimicrobial resistance (AMR) are rising globally and there is concern that increased migration is contributing to the burden of antibiotic resistance in Europe. However, the effect of migration on the burden of AMR in Europe has not yet been comprehensively examined. Therefore, we did a systematic review and meta-analysis to identify and synthesise data for AMR carriage or infection in migrants to Europe to examine differences in patterns of AMR across migrant groups and in different settings. METHODS: For this systematic review and meta-analysis, we searched MEDLINE, Embase, PubMed, and Scopus with no language restrictions from Jan 1, 2000, to Jan 18, 2017, for primary data from observational studies reporting antibacterial resistance in common bacterial pathogens among migrants to 21 European Union-15 and European Economic Area countries. To be eligible for inclusion, studies had to report data on carriage or infection with laboratory-confirmed antibiotic-resistant organisms in migrant populations. We extracted data from eligible studies and assessed quality using piloted, standardised forms. We did not examine drug resistance in tuberculosis and excluded articles solely reporting on this parameter. We also excluded articles in which migrant status was determined by ethnicity, country of birth of participants' parents, or was not defined, and articles in which data were not disaggregated by migrant status. Outcomes were carriage of or infection with antibiotic-resistant organisms. We used random-effects models to calculate the pooled prevalence of each outcome. The study protocol is registered with PROSPERO, number CRD42016043681. FINDINGS: We identified 2274 articles, of which 23 observational studies reporting on antibiotic resistance in 2319 migrants were included. The pooled prevalence of any AMR carriage or AMR infection in migrants was 25·4% (95% CI 19·1-31·8; I2 =98%), including meticillin-resistant Staphylococcus aureus (7·8%, 4·8-10·7; I2 =92%) and antibiotic-resistant Gram-negative bacteria (27·2%, 17·6-36·8; I2 =94%). The pooled prevalence of any AMR carriage or infection was higher in refugees and asylum seekers (33·0%, 18·3-47·6; I2 =98%) than in other migrant groups (6·6%, 1·8-11·3; I2 =92%). The pooled prevalence of antibiotic-resistant organisms was slightly higher in high-migrant community settings (33·1%, 11·1-55·1; I2 =96%) than in migrants in hospitals (24·3%, 16·1-32·6; I2 =98%). We did not find evidence of high rates of transmission of AMR from migrant to host populations. INTERPRETATION: Migrants are exposed to conditions favouring the emergence of drug resistance during transit and in host countries in Europe. Increased antibiotic resistance among refugees and asylum seekers and in high-migrant community settings (such as refugee camps and detention facilities) highlights the need for improved living conditions, access to health care, and initiatives to facilitate detection of and appropriate high-quality treatment for antibiotic-resistant infections during transit and in host countries. Protocols for the prevention and control of infection and for antibiotic surveillance need to be integrated in all aspects of health care, which should be accessible for all migrant groups, and should target determinants of AMR before, during, and after migration.

Graft-versus-host disease in recipients of male unrelated donor compared with parous female sibling donor transplants
Optimal donor selection is critical for successful allogeneic hematopoietic cell transplantation (HCT). Donor sex and parity are well-established risk factors for graft-versus-host disease (GVHD), with male donors typically associated with lower rates of GVHD. Well-matched unrelated donors (URDs) have also been associated with increased risks of GVHD as compared with matched sibling donors. These observations raise the question of whether male URDs would lead to more (or less) favorable transplant outcomes as compared with parous female sibling donors. We used the Center for International Blood and Marrow Transplant Research registry to complete a retrospective cohort study in adults with acute myeloid leukemia, acute lymphoblastic leukemia, or myelodysplastic syndrome, who underwent T-cell replete HCT from these 2 donor types (parous female sibling or male URD) between 2000 and 2012. Primary outcomes included grade 2 to 4 acute GVHD (aGVHD), chronic GVHD (cGVHD), and overall survival. Secondary outcomes included disease-free survival, transplant-related mortality, and relapse. In 2813 recipients, patients receiving male URD transplants (n = 1921) had 1.6 times higher risk of grade 2 to 4 aGVHD (P \u3c .0001). For cGVHD, recipient sex was a significant factor, so donor/recipient pairs were evaluated. Female recipients of male URD grafts had a higher risk of cGVHD than those receiving parous female sibling grafts (relative risk [RR] = 1.43, P \u3c .0001), whereas male recipients had similar rates of cGVHD regardless of donor type (RR = 1.09, P = .23). Donor type did not significantly affect any other end point. We conclude that when available, parous female siblings are preferred over male URDs
