Late-presenting complete heart block after pediatric cardiac surgery

Late presenting complete heart block after pediatric cardiac surgery is a rare complication and its management is well defined once the initial diagnosis in made timely and appropriately. In this report we described a child who underwent atrioventricular septal defect repair with a normal sinus rhythm during the postoperative period, as well as during the first 2 years of follow up.She subsequently developed complete heart block with bradycardia that required insertion of a pacemaker. Here we discuss this unusual late-presenting complication, possible risk factors, and management.     

Factors influencing secondary care pharmacist and nurse independent prescribers’ clinical reasoning: An interprofessional analysis

In the United Kingdom, pharmacist and nurse independent prescribers are responsible for both the clinical assessment of and prescribing for patients. Prescribing is a complex skill that entails the application of knowledge, skills, and clinical reasoning to arrive at a clinically appropriate decision. Decision-making is influenced and informed by many factors. This study, the first of its kind, explores what factors influence pharmacist and nurse independent prescribers during the process of clinical reasoning. A think-aloud methodology immediately followed by a semi-structured interview was conducted with 11 active nurse and 10 pharmacist independent prescribers working in secondary care. Each participant was presented with validated clinical vignettes for the think-aloud stage. Participants chose the clinical therapeutic areas for the vignettes, based on their self-perceived competencies. Data were audio-recorded, transcribed verbatim, and a constant-comparative approach was used for analysis. Influences on clinical reasoning were broadly categorised into themes: social interaction, intrinsic, and contextual factors. These themes showed that intrinsic, sociocultural, and contextual aspects heavily influenced the clinical reasoning processes of prescribers. For example, prescribers were aware of treatment pathways, but chose to refer patient cases to avoid making the final prescribing decision. Exploration of this behaviour in the interviews revealed that previous experience and attitudes such as confidence and cautiousness associated with responsibility were strong influencers within the decision-making process. In addition, strengthening the professional identity of prescribers could be achieved through collaborative work with interprofessional healthcare teams to orient their professional practice from within the profession. Findings from this study can be used to inform the education, training, and practice of independent prescribers to improve healthcare services by improving their professional and interprofessional development.     

Left ventricular volume reduction surgery in the middle East

Heart transplantation is not yet socially acceptable in the Middle East, and left ventricular assist facilities are not generally available in this region. Therefore, left ventricular volume reduction surgery was attempted in 41 patients with end-stage heart failure (33 males; median age, 36.3 years) in 4 Middle Eastern tertiary referral centers between February 1996 and January 2001. Heart failure was due to idiopathic cardiomyopathy in 21 patients, ischemia in 11, rheumatic valvular disease in 8, and viral myocarditis in 1. Associated procedures were aortic valve replacement in 5 patients, mitral valve repair in 25, mitral valve replacement in 7, tricuspid valve repair in 6, and coronary bypass grafting in 8. Hospital mortality was 31.7%. Five patients were lost to follow-up. The survival rate of hospital survivors at 18 months was 65.2%. Three of the surviving patients did not benefit from the operation. Although our results were somewhat disappointing, this operation remains an option for surgeons working in developing areas of the world. It is hoped that better patient selection and new techniques of left ventricular volume reduction that avoid resection of viable muscle will further improve the outcome of this operation.     

Long-term bowel disorders following radial cystectomy: an underestimated issue?

Purpose

Patients after radical cystectomy (RC) frequently complain about bowel disorders (BDs). Reports addressing related long-term complications are sparse. This cross-sectional study assessed changes in bowel habits (BH) after RC.

Methods

A total of 89 patients with a minimum follow-up ≥1 year after surgery were evaluated with a questionnaire. Patients with BD prior to surgery were excluded. Symptoms such as diarrhea, constipation, bloating/flatulence, incomplete defecation, uncontrolled stool loss, and impact on quality of life (QoL) were assessed.

Results

A total of 46.1 % of patients reported changes in BH; however, only 25.8 % reported experiencing related dissatisfaction. Primary causes of dissatisfaction were diarrhea and uncontrolled stool loss. The most common complaints were bloating/flatulence and the feeling of incomplete defecation, but these symptoms did not necessarily lead to dissatisfaction or impairment in quality of life. No difference was identified between an orthotopic neobladder and ileal conduit, and even patients without bowel surgery were affected. QoL, health status, and energy level were significantly decreased in unsatisfied patients.

Conclusions

About 25 % of patients complain about BDs after RC. More prospective studies assessing symptoms, comorbidities, and dietary habits are necessary to address this issue and to identify strategies for follow-up recommendations.

     

White paper on antimicrobial stewardship in solid organ transplant recipients

Antimicrobial stewardship programs (ASPs) have made immense strides in optimizing antibiotic, antifungal, and antiviral use in clinical settings. However, although ASPs are required institutionally by regulatory agencies in the United States and Canada, they are not mandated for transplant centers or programs specifically. Despite the fact that solid organ transplant recipients in particular are at increased risk of infections from multidrug-resistant organisms, due to host and donor factors and immunosuppressive therapy, there currently are little rigorous data regarding stewardship practices in solid organ transplant populations, and thus, no transplant-specific requirements currently exist. Further complicating matters, transplant patients have a wide range of variability regarding their susceptibility to infection, as factors such as surgery of transplant, intensity of immunosuppression, and presence of drains or catheters in situ may modify the risk of infection. As such, it is not feasible to have a “one-size-fits-all” style of stewardship for this patient population. The objective of this white paper is to identify opportunities, risk factors, and ASP strategies that should be assessed with solid organ transplant recipients to optimize antimicrobial use, while producing an overall improvement in patient outcomes. We hope it may serve as a springboard for development of future guidance and identification of research opportunities.
