Aspirin and nonaspirin nonsteroidal antiinflammatory drug use and occurrence of colorectal adenoma in Black American women

Evidence suggests that aspirin use reduces the occurrence of colorectal neoplasia. Few studies have investigated the association among Black Americans, who are disproportionately burdened by the disease. We assessed aspirin use in relation to colorectal adenoma among Black women. The Black Women's Health Study is a prospective cohort of self-identified Black American women established in 1995. Participants reported regular aspirin use on baseline and follow-up questionnaires. Beginning in 1999, participants reported undergoing a colonoscopy or sigmoidoscopy, the only procedures through which colorectal adenomas can be diagnosed. Multivariable logistic regression was used to estimate odds ratios (OR) and 95% confidence intervals (CI) for associations between aspirin use and colorectal adenoma among 34 397 women who reported at least 1 colonoscopy or sigmoidoscopy. From 1997 through 2018, 1913 women were diagnosed with an adenoma. Compared to nonaspirin users, regular users had 14% (OR = 0.86, 95% CI: 0.78-0.95) lower odds of adenoma. The odds of adenoma decreased with increasing duration of aspirin use (≥10 years: OR = 0.80, 95% CI: 0.66-0.96). Initiating aspirin at a younger age was associated with a reduced adenoma occurrence (age < 40 years at initiation: OR = 0.69, 95% CI: 0.55-0.86). Regular aspirin use was associated with a decreased odds of colorectal adenoma in our study of Black women. These findings support evidence demonstrating a chemopreventive impact of aspirin on colorectal neoplasia and suggest that aspirin may be a useful prevention strategy among US Black women.     

‘It felt like there was always someone there for us’: Supporting children affected by domestic violence and abuse who are identified by general practice

One in five children in the UK are affected by domestic violence and abuse. However, primary care clinicians (GPs and nurses) struggle to effectively identify and support children and young people living in homes where it is present. The IRIS+ (Enhanced Identification and Referral to Improve Safety) training and advocacy support intervention aimed to improve how clinicians respond to children and young people affected by domestic violence and abuse. IRIS+ training was delivered as part of a feasibility study to four general practices in an urban area in England (UK). Our mixed method design included interviews and questionnaires about the IRIS+ intervention with general practice patients, including children and young people as well as with clinicians and advocacy service providers. We collected the number of identifications and referrals by clinicians of children experiencing domestic violence and abuse through a retrospective search of medical and agency records 10 months after the intervention. Forty-nine children exposed to domestic violence and abuse were recorded in medical records. Thirty-five children were referred to a specialist domestic violence and abuse support service over a period of 10 months. Of these, 22 received direct or indirect support. The qualitative findings indicated that children benefitted from being referred by clinicians to the service. However, several barriers at the patient and professional level prevented children and young people from being identified and supported. Some of these barriers can be addressed through modifications to professional training and guidance, but others require systematic and structural changes to the way health and social care services work with children affected by domestic violence and abuse.     

Airway pressure release ventilation for in-vivo donor lung management and lung transplant outcomes

Background:Airway pressure release ventilation (APRV) can be used for cadaveric donor lung recruitment. APRV elevates PaO₂ in donor lungs; however, reported outcomes in recipients with APRV-managed donor lungs are limited. Methods:We retrospectively reviewed patients who underwent lung transplantation (LTx) from 2012 to 2013 and divided them into two groups based on mode of ventilation used during donor management and organ extraction (A: non-APRV; B: APRV). Kaplan-Meier method and multivariate Cox regression were used for analysis. Results:We found 126 LTx recipients (LTxRs); 9 were excluded for use of portable ventilation perfusion systems. Of the remaining 117 patients, 81 (69%) were in Group A; 36 (31%) were in Group B. Preoperative LTxR characteristics (age, sex, lung allocation score, end-stage lung disease type) were comparable between groups. Donors for Group B were older (P=0.03) and had higher body mass index (BMI) (P<0.001), higher incidence of death from chest trauma (P=0.008), longer ventilation duration after brain death (P<0.001), and higher pre-explant PaO₂/FiO₂ ratios (P<0.001). Post-LTx duration of mechanical ventilation, hospital stay, and median survival were similar in both groups. Risk of death was comparable between the two groups at the end of follow-up (HR =1.42; 95% CI: 0.57-3.56; P=0.45). Conclusions:APRV is a safe and effective pre-LTx donor lung management strategy. Short- and long-term survival outcomes were comparable in LTx recipients, irrespective of donor ventilation mode. APRV may help recruit lungs from older donors with higher BMI who die from chest trauma and have anticipated longer ventilation duration.     

The incidence of negative intraoperative findings after unsuccessful hydrostatic reduction of ileocolic intussusception in children: A retrospective analysis

Background

There is a lack of studies addressing the occurrence of negative intraoperative findings (that is the absence of intussusception) after an unsuccessful hydrostatic reduction of an ileocolic intussusception. The aim of this study is to determine the incidence of negative intraoperative findings after unsuccessful hydrostatic reduction of ileocolic intussusception.

Variability of pressure at the pressure garment-scar interface in children after burn: A pilot longitudinal cohort study

Background

Current consensus for the ideal pressure range at the pressure garment to scar interface is 15–25 mmHg. Interface pressure variability has been reported at new pressure garment fitting in children. Pressure reductions up to 25% have been recorded over one month in adults.
