Defensive medicine: A symptom of uncertainty?

Defensive medicine is a well-documented phenomenon and refers to the practice of over-cautious management of patients, leading to excessive clinical activity such as over-investigation, unnecessary appointments and additional interventions. Adopting this approach is not in the best interest of patients and can lead to clinical reasoning being replaced by lists, guidelines and algorithms which do not consider the complexity of a patients presentation or the reasoning inherent in good clinical judgement. The drivers of defensive medicine are varied and include a high level of uncertainty alongside other factors including clinical experience with past cases, system pressures and patient expectations.

Barriers to access to ear and hearing care services in low- and middle- income countries: A scoping review.

People living in low- and middle- income countries (LMICs) meet significant challenges in accessing ear and hearing care (EHC) services. We conducted a scoping review to identify and summarise such barriers, to recognise gaps in the literature, and to identify potential solutions. Reviewers independently screened titles, abstracts and full-text articles and charted data.

Safety and effectiveness of Omnitrope (somatropin) in PATRO Children: a multi-center, post-marketing surveillance study comparison of US and international cohort data.

Unlabelled: There are known geographical differences in growth hormone deficiency (GHD) patient populations and treatment practices. Here, we present a comparison of safety and effectiveness data from patients treated with recombinant human growth hormone (rhGH) in the USA versus other countries. PAtients TReated with Omnitrope® (PATRO) Children is an international, non-interventional study with Omnitrope® (somatropin, Sandoz Inc.

Integrating services to improve quality of care for women living with HIV: A global systematic review.

Objectives: The aim was to review and analyse evidence on the impact of service integration on quality of care for women living with HIV.

Methods: Evidence search in September 2020 using the PICO format yielded 60 potential papers. Inclusion required evidence of measurement of an outcome associated with service delivery within a system showing clear integration of services exclusively for women living with HIV.

Topographical anatomy of the annulus of Zinn.

The anatomy and even existence of a common tendinous origin of the extraocular eye muscles, or annulus of Zinn, has widely been debated in anatomical literature. This study explored the anatomical origins of the recti muscles, their course into the orbit and the dural connections of the common tendinous origin with the skull base. Twenty orbits of ten adult human cadavers were dissected.

White-coat hypertension/effect is associated with higher arterial stiffness and stroke events.

Objectives: The risk profile of white-coat hypertension/effect (WCH/E) remains unclear. This study aimed to investigate the relationship between WCH/E, markers of cardiovascular risk and cerebrovascular events.

Methods: This is a sub-group analysis of The Arterial Stiffness In lacunar Stroke and Transient ischemic attack (ASIST) study, which recruited 96 patients aged at least 40 years old with a diagnosis of transient ischemic attack or lacunar stroke in the preceding 14 days.

Bone mineral density, kidney function and participant-reported outcome measures in women who switch from tenofovir disoproxil emtricitabine and a nonnucleoside reverse transcriptase inhibitor to abacavir, lamivudine and dolutegravir.

Objectives: Tenofovir disoproxil fumarate (TDF) is associated with reduced bone mineral density (BMD). The aim of the study was to evaluate changes in BMD in women who switched from TDF, emtricitabine and a nonnucleoside reverse transcriptase inhibitor (TDF/FTC/NNRTI) to abacavir, lamivudine and dolutegravir (ABC/3TC/DTG).

Methods: We conducted a randomized controlled trial in which women aged ≥ 40 years were randomized 1:2 to continue TDF/FTC/NNRTI or switch to ABC/3TC/DTG.

Follicle-stimulating hormone in postmenopausal women living with HIV: a prevalence study.

Objectives: We examined follicle-stimulating hormone (FSH) levels in women living with HIV aged > 45 reporting ≥ 12 months' amenorrhoea, and investigated correlation with menopausal symptoms.

Methods: A cross-sectional substudy of 85 women from the Positive Transitions through the Menopause (PRIME) Study who reported irregular periods at entry into the PRIME Study and ≥ 12 months' amenorrhoea at recruitment into this substudy. Serum FSH was supplemented with clinical data and menopausal symptom assessment.

Balloon Seal Separation Leading to SAPIEN 3 Transcatheter Heart Valve Deployment Failure: Complications and Management.

We present two cases of failure of balloon inflation secondary to balloon separation from the delivery catheter when implanting the SAPIEN 3 transcatheter heart valve (Edwards Lifesciences, Irvine, CA, USA). Although very uncommon, this is a potentially disastrous complication of transcatheter intervention. Case 1 highlights the complexity of the problem when it occurs and subsequent complications.
