Prevalence of hypertension and cardiovascular risk factors among long‐term AIDS survivors: A report from the field

HIV infection is associated with increased risk and progression of cardiovascular disease (CVD), yet little is known about the prevalence of CVD risk factors among long‐term AIDS survivors in resource‐limited settings. Using routinely collected data, we conducted a retrospective study to describe the prevalence of CVD risk factors among a cohort of HIV‐infected patients followed for over 10 years in Port‐au Prince, Haiti. This cohort includes 910 adults who initiated antiretroviral therapy (ART) between 2003 and 2004 and remained in care between 2014 and 2016 when routine screening for CVD risk factors was implemented at a large clinic in Haiti. A total of 397 remained in care ≥10 years and received screening. At ART initiation, 59% were female, median age was 38 years (IQR 33‐44), and median CD4 count was 117 cells/mm³ (IQR 34‐201). Median follow‐up time from ART initiation was 12.1 years (IQR 11.7‐12.7). At screening, median CD4 count was 574 cells/mm³ (IQR 378‐771), and 84% (282 of 336 screened) had HIV‐1 RNA < 1000 copies/mL. Seventy‐four percent of patients had at least 1 risk factor including 58% (224/385) with hypertension, 8% (24/297) diabetes, 43% (119/275) hypercholesterolemia, 8% (20/248) active smoking, and 10% (25/245) obesity. Factors associated with hypertension were age (adjusted OR 1.06, P < .001) and weight at screening (adjusted OR 1.02, P = .019). Long‐term AIDS survivors have a high prevalence of CVD risk factors, primarily hypertension. Integration of cardiovascular screening and management into routine HIV care is needed to maximize health outcomes among aging HIV patients in resource‐limited settings.     

Adhesive strips versus subcuticular suture for mediansternotomy wound closure

Abstract Background and Aim: This prospective randomized study was undertaken to compare the use of the 3M™ Steri‐Strip™ S Surgical Skin closure system with a running absorbable subcuticular suture technique for skin closure following a mediansternotomy for cardiac surgical procedures. Methods: Thirty‐six patients undergoing a mediansternotomy for a cardiac surgical procedure were prospectively randomized to either Steri‐Strip S or subcuticular suture for wound closure. The wounds were evaluated on postoperative days 7 and 21 for erythema, edema, pain, cosmesis, and the time taken to close the incision. Results: Skin closure with Steri‐Strip S was faster (5.33 ± 1.32 minutes steri‐strips vs. 6.07 ± 0.91 sutures; p = 0.06) and resulted in significantly less erythema and edema, but no difference in pain or cosmesis after seven days. Following 21 days, there was no difference in pain, edema, or cosmesis between the groups. However, patients receiving steri‐strips continue to have less erythema. Conclusions: Both Steri‐Strip S and absorbable sutures are effective techniques for skin closure following a mediansternotomy incision for cardiac surgical procedures. Steri‐Strip S can decrease the amount of erythema, but results in no significant difference in pain, cosmesis, or edema compared to the traditional subcuticular wound closure technique.

Long-term outcomes after uncomplicated mild traumatic brain injury: a comparison with trauma controls

The question as to whether mild traumatic brain injury (mTBI) results in persisting sequelae over and above those experienced by individuals sustaining general trauma remains controversial. This prospective study aimed to document outcomes 1 week and 3 months post-injury following mTBI assessed in the emergency department (ED) of a major adult trauma center. One hundred and twenty-three patients presenting with uncomplicated mTBI and 100 matched trauma controls completed measures of post-concussive symptoms and cognitive performance (Immediate Post-Concussion Assessment and Cognitive Testing battery; ImPACT) and pre-injury health-related quality of life (SF-36) in the ED. These measures together with measures of psychiatric status (the Mini-International Neuropsychiatric Interview [MINI]) pre- and post-injury, the Hospital Anxiety and Depression Scale, Visual Analogue Scale for Pain, Functional Assessment Questionnaire, and PTSD Checklist-Specific, were re-administered at follow-up. Participants with mTBI showed significantly more severe post-concussive symptoms in the ED and at 1 week post-injury. They performed more poorly than controls on the Visual Memory subtest of the ImPACT at 1 week and 3 months post-injury. Both the mTBI and control groups recovered well physically, and most were employed 3 months post-injury. There were no significant group differences in psychiatric function. However, the group with mild TBI was more likely to report ongoing memory and concentration problems in daily activities. Further investigation of factors associated with these ongoing problems is warranted.     

Is Clostridium difficile infection a particular problem after reversal of ileostomy?

Aim Clostridium difficile infection (CDI) is a cause of morbidity and mortality in hospitals. Various independent risk factors have been identified, including age and antibiotic exposure. This study attempted to determine whether surgery and associated antibiotic use influence the development of CDI. Method A retrospective review of all patients with a diagnosis of CDI diagnosed during admission to a colorectal unit was conducted over a 20‐month period. Patient records were cross‐referenced with a microbiology database to identify previous episodes of infection and cases of recurrence. Results There were 38 CDI episodes in 29 patients, including nine with recurrence. In 33, the use of antibiotics prior to the onset of CDI was documented, but in 14 (37%) patients this was limited to perioperative prophylaxis. The incidence of CDI after various procedures was as follows: ileostomy closure (4.2%), right hemicolectomy (2.1%) and anterior resection (1%). Conclusion Ileostomy closure may carry a higher risk of CDI.
