Creation and evaluation of a three-dimensional-printed synthetic vas deferens for microsurgical training.

Introduction: Individuals choose to undergo vasectomy reversal for a variety of reasons, including remarriage or due to the death of a child. To be proficient in this procedure, the surgeons need to be high volume and the trainees require a safe environment to develop their microsurgical skills. To overcome this challenge, we used three-dimensional (3D) printing to create a synthetic model of the vas deferens with properties similar to the human vas deferens.

Combination of a monofocal and one type of extended depth-of-focus (zonal refractive) intraocular lens (COMEDI) in bilateral cataract surgery protocol: a monocentric, randomised, parallel group trial in cataract surgery.

Introduction: Modern intraocular lens (IOL) designs for cataract treatment can be broadly classified into three focal range categories; monofocal, extended depth-of-focus (EDOF) and multifocal IOLs.Monofocal IOLs allow spectacle independence for one focus, typically distance. In contrast, EDOF IOLs provide a greater range of vision, extending spectacle independence to intermediate distance, while multifocal IOLs enable spectacle independence at all distances with the drawback of positive dysphotopsias and reduced contrast perception.

Adapting the Diabetes Prevention Program for low- and middle-income countries: preliminary implementation findings from lifestyle Africa.

Rates of cardiovascular disease and diabetes are rising in low- and middle-income countries (LMIC), but there is a dearth of research devoted to developing and evaluating chronic disease interventions in these settings, particularly in Africa. Lifestyle Africa is a novel, culturally adapted version of the Diabetes Prevention Program (DPP) being evaluated in an ongoing community-based cluster-randomized trial in an underresourced urban community in South Africa. The purpose of this study is to describe the adaptations and adaptation process used to develop the program and to report preliminary implementation findings from the first wave of groups (n = 11; 200 individuals) who participated in the intervention.

Reasons for nonadherence and response to treatment in an adherence intervention trial for relapsing-remitting multiple sclerosis patients.

Objectives: To explore whether patients in an adherence trial who appeared not to take disease modifying therapy (DMT) for avoidance reasons could be reliably identified, by observational coding, for their main reason of not taking DMT. To determine whether reason groups could be distinguished by clinical and self-report psychological characteristics and intervention outcomes.

Method: Participants were multiple sclerosis patients (N = 78, 88.
