De novo tacrolimus extended-release tablets (LCPT) versus twice-daily tacrolimus in adult heart transplantation: Results of a single-center non-inferiority matched control trial.

Extended-release tacrolimus for prophylaxis of allograft rejection in orthotopic heart transplant (OHT) recipients is currently not FDA-approved. One such extended-release formulation of tacrolimus known as LCPT allows once-daily dosing and improves bioavailability compared to immediate-release tacrolimus (IR-tacrolimus). We compared the efficacy and safety of LCPT to IR-tacrolimus applied de novo in adult OHT recipients. Twenty-five prospective recipients on LCPT at our center from 2017 to 2019 were matched 1:2 with historical control recipients treated with IR-tacrolimus based on age, gender, and baseline creatinine. The primary composite outcome of death, acute cellular rejection, and/or new graft dysfunction within 1 year was compared using non-inferiority analysis. LCPT demonstrated non-inferiority to IR-tacrolimus, with a primary outcome risk reduction of 20% (90% CI: -40%, -.5%; non-inferiority P = .001). Tacrolimus trough levels peaked at 2-3 months and were higher in LCPT (median 14.5 vs. 12.7 ng/ml; P = .03) with similar dose levels (LCPT vs. IR-tacrolimus: .08 vs. .09 mg/kg/day; P = .33). Cardiovascular-related readmissions were reduced by 62% (P = .046) in LCPT patients. The complication rate per transplant admission and all-cause readmission rate did not differ significantly. These results suggest that LCPT is non-inferior in efficacy to IR-tacrolimus with a similar safety profile and improved bioavailability in OHT.

Identification of botanicals with potential therapeutic use against methicillin-resistant Staphylococcus aureus (MRSA) infections.

Staphylococcus aureus is an opportunistic pathogen. Over- and improper-use of pharmaceuticals against S. aureus has led to the development of antibiotic resistance, including methicillin-resistant S. aureus (MRSA). This study examined the efficacy of botanical extracts as an alternative form of treatment to S. aureus and MRSA, including penicillin/methicillin-resistant S. aureus (PenR ), and multidrug resistant S. aureus (MDR). Initial screening of botanicals was done via a minimum inhibitory concentration procedure. In addition, a temporal growth curve was performed in order to quantify the growth of the bacteria in the presence of the extracts. Results demonstrated 13 botanicals that had varying activities against S. aureus, PenR , and MDR. These botanicals were separated into mild, moderate, and highly efficacious based on the concentration needed to inhibit bacterial growth. These results propose a comparison of botanical-derived antimicrobial extracts that may be utilized against S. aureus and different antibiotic resistant strains of MRSA.

Unusual diagnosis in a patient with minor ankle trauma.

We present the case of a 23 year-old male who sustained an anterior tibial artery pseudoaneurysm after an apparently innocuous soccer injury. The patient presented with sudden onset severe pain and swelling one week after the injury. The diagnosis was made using duplex ultrasound, and confirmed with CT angiography. Definitive management consisted of endovascular platinum microcoiling. One year later, the patient is asymptomatic and remains active. A review of the epidemiology, diagnosis, and treatment of arterial pseudoaneurysm is presented. Bedside ultrasound in the emergency department may be a useful adjunct in the early identification of pseudoaneurysms.

The epidemiology and management of recent-onset atrial fibrillation and flutter presenting to the Emergency Department.

OBJECTIVES: Atrial fibrillation (AF) and flutter are common tachyarrhythmias seen in the Emergency Department (ED). The management of recent-onset AF remains poorly defined. Two management strategies have been proposed: rhythm control versus rate control. The aims of this study were to investigate the epidemiology and management of recent-onset AF presenting to one large tertiary ED. METHODS: Retrospective analysis of ED records was carried out using the ED PAS database to identify eligible patients presenting between 1 July 2009 and 30 June 2011 with onset of AF in the previous 7 days. Patients were included for analysis if it was their first presentation, first diagnosis or a paroxysm of atrial fibrillation. RESULTS: A total of 494 patients (625 presentations) were analysed. AF (n=564; 90.2%) and flutter (n=61; 9.8%) were the presenting rhythms. In all, 374 (53.8%) presentations were paroxysmal atrial fibrillation. For patients with AF, rhythm control was attempted in 171 (55.0%) patients presenting less than 48 h after symptom onset. Pharmacotherapy was the approach in 105 (31.4%) patients, compared with direct current cardioversion (n=45; 26.3%). Twenty-one patients received both. Flecainide (n=85) and amiodarone (n=33) were the main first-line pharmacotherapies, restoring sinus rhythm in 81.3 and 81.4% of patients, respectively. The overall efficacy of direct current cardioversion in restoring sinus rhythm was similar (78.8%). Eighty-one patients presented more than 48 h after symptom onset. Of those patients managed in the ED (n=38; 71.7%) were managed with rate control. The majority of patients with atrial flutter presented less than 48 h after symptom onset (n=48; 78.7%). Sixteen of these patients were managed with rhythm control strategies in the ED. CONCLUSION: The epidemiology of recent-onset AF in this series is comparable with previous publications. Rhythm control was only attempted in approximately half of all eligible patients. There was no single-favoured management strategy. Our results mirror the literature in emphasizing the variation in management and the lack of robust evidence guiding the management of recent-onset AF and flutter.

Do vascular risk factors explain the association between socioeconomic status and stroke incidence: a meta-analysis.

BACKGROUND: Reduced socioeconomic status (SES) is associated with an increased risk of stroke, although the mechanism is not clear. It may be that those with lower SES have a greater burden of classic vascular risk factors. METHODS: Our aim was to quantify the extent to which classic vascular risk factors explain the association between SES and stroke incidence. We conducted a systematic review and meta-analysis of studies examining the association of SES and stroke incidence, where classic vascular risk factors were considered. Searching MEDLINE, EMBASE and the Cochrane Library from 1980 onwards we identified 17 studies, 12 of these studies provided sufficient information to allow a meta-analysis. From each study the increased risk of stroke incidence, where the lowest socioeconomic category was compared with the highest, was recorded and pooled. The stroke incidence risks, adjusted for grouped classic risk factors, were also pooled. Review Manager 5 software was used for all analyses and results were analysed using hazard ratios (HR, 95% confidence interval, 95% CI) with a random effects model. RESULTS: Those with a lower SES were more likely to have a stroke (HR 1.67; 95% CI 1.46-1.91). Additional risk was reduced, but not eliminated, when classic vascular risk factors were adjusted for (HR 1.31; 95% CI 1.16-1.48). CONCLUSION: Low SES is associated with an increased risk of stroke that is partly explained by known classic vascular risk factors.

"Knife before wife": an exploratory study of gender and the UK medical profession.

PURPOSE: The paper aims to explore the increasing feminisation of the medical profession and career progression of women in the medical profession. Furthermore, the paper explores the implications of gender segregation in the medical profession for health service provision. DESIGN/METHODOLOGY/APPROACH: The paper presents an overview of studies in this area and draws upon primary, empirical research with medical practitioners and medical students. However, unlike most other studies the sample includes male and female participants. The research involved elite interviews and self-completion questionnaires in order to provide perspectives of both male and female medical practitioners and medical students. FINDINGS: The findings are consistent with those of other studies; that gender discrimination and segregation is still prevalent in the medical profession. But there are significant differences in perceptions between the genders. Moreover, it is concluded that the gendered career structure and organisational culture of the health sector and medical profession create a role conflict between personal and professional lives. The current difficulties in reconciling this role conflict create barriers to the career progression of women in the medical profession. RESEARCH LIMITATIONS/IMPLICATIONS: Further research in this area could include a longitudinal study of medical students and the impact of changes in the design of medical training and career structures to assess whether these changes enable female career progression in the medical profession. Further analysis is needed of gendered practices and career development in specific specialist areas, and the role of the medical profession, NHS and Royal Colleges should play in addressing gender and career progression in medicine. PRACTICAL IMPLICATIONS: Gender segregation (vertical and horizontal) in the medical profession will have implications for the attraction, retention and increased shortages of practitioners in hospital and surgical specialities with the resultant economic and health provision inefficiencies. ORIGINALITY/VALUE: The paper provides a review of literature in this area, thereby providing a longitudinal perspective of gender and the medical profession. Moreover, the research sample includes both male and female medical practitioners and medical students, which provides perspectives from both genders and from those who have experience within the medical profession and from those beginning their career in the medical profession. The research will be of value to the medical profession, the NHS and Royal Colleges of Medicine.
