Although pulmonary artery banding remains a useful palliation in bi-ventricular shunting lesions, single-stage repair holds several advantages. We investigate outcomes of the former approach in high-risk patients.
Retrospective cohort study including all pulmonary artery banding procedures over 9 years, excluding single ventricle physiology and left ventricular training.
Banding was performed in 125 patients at a median age of 41 days (2–294) and weight of 3.4 kg (1.8–7.32). Staged repair was undertaken for significant co-morbidity in 81 (64.8%) and anatomical complexity in 44 (35.2%). The median hospital stay was 14 days (interquartile range 8–33.5) and 14 patients (11.2%) required anatomical repair before discharge. Nine patients died during the initial admission (hospital mortality 7.2 %) and five following discharge (inter-stage mortality 4.8%). Of 105 banded patients who survived, 19 (18.1%) needed inter-stage re-admission and 18 (14.4%) required unplanned re-intervention. Full repair was performed in 93 (74.4%) at a median age of 13 months (3.1–49.9) and weight of 8.5 kg (3.08–16.8). Prior banding, 54% were below the 0.4th weight centile, but only 28% remained so at repair. Post-repair, 5/93 (5.4%) developed heart block requiring permanent pacemaker, and 11/93 (11.8%) required unplanned re-intervention. The post-repair mortality (including repairs during the initial admission) was 6/93 (6.5%), with overall mortality of the staged approach 13.6% (17/125).
In a cohort with a high incidence of co-morbidity, pulmonary artery banding is associated with a significant risk of re-intervention and mortality. Weight gain improves after banding, but heart block, re-intervention, and mortality remain frequent following repair.
Differential attainment (DA) amongst Black and Minority Ethnic (BAME) medical students and postgraduate trainees including Psychiatry trainees has been extensively documented in medical education, with non-white medical students being 2.5 times more likely to fail high-stake examinations compared to their White counterparts. The Equality Act 2010 places a responsibility on public bodies such as Royal Colleges to address discrimination in training and assessment. Understanding DA in undergraduate medical education can help understand DA in the postgraduate setting. Consequently, this systematic review aims to detect the processes that enable and impede DA in UK undergraduate medical education.
Seven online databases including PubMed, Scopus, PyschInfo, and ERIC were searched. A formal grey literature search was also conducted. Inclusion criteria comprised studies dated from January 1995 to present and included UK undergraduate medical students. We present the preliminary findings from 13 papers, analysed to create a conceptual framework for a further mixed methods analysis. The studies were critically appraised for methodological quality.
Five key themes emerged from the preliminary analysis of 13 papers. BAME students experienced:
Being ‘divergent’: Not feeling part of the current organisational learning milieu
Lack of social capital: Difficulty in being absorbed into existing ‘networks’ of relationships in a manner that is ‘approachable’ and not ‘intimidating’
Continuum of discrimination: ‘Indirect’ impact of subtle communication processes in the learning environment undermining individual ‘belief’ in own performance
Institutional discriminatory factors: Culture, rules, norms, and behavioural routines of educators that lead to differential outcomes for learners
Lack of external support: Relative lack of interventions tackling DA.
The key finding of this review is that British BAME undergraduate medical students experience discriminatory behaviours early in medical schools that impact on personal, educational, and professional outcomes. These factors may need to be borne in mind by postgraduate training organisations such as the Royal College of Psychiatrists as they commence the challenging task of addressing DA.
Morbidity is defined as a state of being unhealthy or of experiencing an aspect of health that is “generally bad for you”, and postoperative morbidity linked to paediatric cardiac surgery encompasses a range of conditions that may impact the patient and are potential targets for quality assurance.
As part of a wider study, a multi-disciplinary group of professionals aimed to define a list of morbidities linked to paediatric cardiac surgery that was prioritised by a panel reflecting the views of both professionals from a range of disciplines and settings as well as parents and patients.
We present a set of definitions of morbidity for use in routine audit after paediatric cardiac surgery. These morbidities are ranked in priority order as acute neurological event, unplanned re-operation, feeding problems, the need for renal support, major adverse cardiac events or never events, extracorporeal life support, necrotising enterocolitis, surgical site of blood stream infection, and prolonged pleural effusion or chylothorax. It is recognised that more than one such morbidity may arise in the same patient and these are referred to as multiple morbidities, except in the case of extracorporeal life support, which is a stand-alone constellation of morbidity.
It is feasible to define a range of paediatric cardiac surgical morbidities for use in routine audit that reflects the priorities of both professionals and parents. The impact of these morbidities on the patient and family will be explored prospectively as part of a wider ongoing, multi-centre study.
An analysis of a cluster of New Delhi metallo-β-lactamase-l-producing Klebsiella pneumoniae (NDMl-Kp) and a retrospective case-cohort analysis of risk factors for acquisition in contacts of NDM1-Kp-positive patients.
A 1,100-bed Canadian academic tertiary care center.
Two index patients positive for NDMl-Kp as well as 45 contacts (roommates, ward mates, or environmental contacts) were investigated.
Retrospective chart reviews of all patients colonized or infected with NDM1-Kp as well as contacts of these patients were performed in order to describe the epidemiology and impact of infection prevention and control measures. A case-cohort analysis was conducted investigating 45 contacts of NDM1-Kp-positive patients to determine risk factors for acquisition of NDM1-Kp. Rectal swabs were screened for NDMl-Kp using chromogenic agar. Presence of blaNDM-1 was confirmed by multiplex polymerase chain reaction. Clonality was assessed with pulsed-field gel electrophoresis (PFGE) using restriction enzyme XbaI.
Two index cases carrying NDM1-Kp with different PFGE patterns were identified. Nosocomial transmission to 7 patients (4 roommates, 2 ward mates, and 1 environmental contact) was subsequenüy identified. Risk factors for acquisition of NDM1-Kp were a history of prior receipt of certain antibiotics (fluoroquinolones [odds ratio (OR), 16.8 (95% confidence interval [CI], 1.30-58.8); P = .005], trimethoprim-sulfamethoxazole [OR, 11.3 (95% CI, 1.84-70.0); P = .01], and carbapenems [OR, 16.8 (95% CI, 1.79-157.3); P = .04]) and duration of exposure to NDM1-Kp-positive roommates (26.5 vs 6.7 days; P< .001).
Two distinct clones of NDM1-Kp were transmitted to 7 inpatient contacts over several months. Implementation of contact precautions, screening of contacts for NDM1-Kp carriage, and attention to environmental disinfection contributed to the interruption of subsequent spread of the organism. The appropriate duration and frequency of screening contacts of NDMl-Kp-positive patients require further study.
