Importance: Routine preoperative blood tests and electrocardiograms before low-risk surgery do not prevent adverse events or change management but waste resources and can cause patient harm. Given this, multispecialty organizations recommend against routine testing before low-risk surgery.

Objective: To determine whether a multicomponent deimplementation strategy (the intervention) would reduce low-value preoperative testing before low-risk general surgery operations.

Background: The full-scale invasion disrupted health care in Ukraine, leading to the displacement of physicians and affecting their access to subspecialist consultations. HealUA, a mobile application, was designed to provide secure and timely remote physician-to-physician consultations. We aimed to assess the implementation of the HealUA mobile application for peer-to-peer physician consultations in Ukraine during the Russian invasion.

Context: Little is known about how patients' emotions impact the choice between hemi- and total thyroidectomy (TT) for low-risk thyroid cancer (LR-TC) and how these emotions change after treatment.

Objective: To investigate thyroid cancer-specific fear and worry both before and after treatment of LR-TC with hemi- or TT.

Methods: This prospective cohort study enrolled adults with confirmed or likely LR-TC at 15 institutions.

Handball is a team sport characterised by physical interaction with other opponents. This interaction produces a high load on the players that can manifest itself in various ways, from discomfort to prolonged injuries due to tears caused by excessive load. In order to establish correct protocols for application in women's teams, context- and gender-specific reference data must be available.

Introduction: Thyroid cancer diagnosis often evokes strong negative emotions in patients, yet little is understood about such responses in those with benign thyroid nodules. This study explored the impact of a hypothetical cancer diagnosis, the provision of treatment information, and emotional support from surgeons on patients with benign nodules.

Methods: Patients within 30 d of a thyroid nodule biopsy were asked to imagine their nodule was cancerous and write down their feelings about this diagnosis.

Background: Although primary hyperparathyroidism (PHPT) is readily diagnosed biochemically and can be cured with low-risk surgery, it is often underrecognized and undertreated. Our objectives were to characterize, within our health system, how often patients with hypercalcemia were evaluated for PHPT and how often patients with PHPT underwent definitive treatment with parathyroidectomy.

Methods: Ambulatory patients aged 18 years or older seen at our health system between January 2018 and June 2023 with chronic hypercalcemia were identified from the medical record.

While patient-level determinants of total thyroidectomy use have been well described, surgeon-level drivers of more extensive surgery are present and less well described. This survey sought to examine the associations between surgeons' operative recommendations, their beliefs about cancer, and their attitudes about medical maximizing-minimizing. A mixed-mode, cross-sectional survey was administered in September 2020 via mail and email to 222 thyroid surgeons identified in the Centers for Medicare & Medicaid Services Provider Utilization and Payment Physician and Other Practitioners dataset.

Background: Spanish-speaking trauma and burn patients have unique needs in their postdischarge care navigation. The confluence of limited English proficiency, injury recovery, mental health, socioeconomic disadvantages, and acute stressors after hospital admission converge to enhance patients' vulnerability, but their specific needs and means of meeting these needs have not been well described.

Study Design: This prospective, cross-sectional survey study describes the results of a multi-institutional initiative devised to help Spanish-speaking trauma and burn patients in their care navigation after hospitalization.

Article Synopsis
  • The study evaluates how patients with low-risk thyroid cancer prioritize treatment outcomes after their surgical choices, emphasizing the emotional impact of their diagnosis on decision-making.
  • Participants rated outcomes at the time of surgery decision and again after 9 months, revealing that patients' valuations changed significantly over time.
  • Results indicate that after experiencing treatment, patients shifted focus from concerns about cancer recurrence to valuing quality of life aspects like energy levels, suggesting surgeons need to consider these changing priorities in discussions about treatment options.

Introduction: Consensus is lacking regarding the optimal strategy to influence surgeons' behaviors to reduce low-value surgical care. Comprehensively describing the existing body of literature that seeks to intervene on surgeons' preoperative decision-making may aid in structuring future behavior change strategies.

Methods: We performed a scoping review using four databases (Medical Literature Analysis and Retrieval System Online, Embase, Web of Science, and Cumulated Index to Nursing and Allied Health Literature) for articles that tested the effect of behavioral-based interventions on any aspect of surgeons' decision-making in the preoperative setting.

Introduction: Despite multispecialty recommendations to avoid routine preoperative testing before low-risk surgery, the practice remains common and de-implementation has proven difficult. The goal of this study as to elicit determinants of unnecessary testing before low-risk surgery to inform de-implementation efforts.

Methods: We conducted focused ethnography at a large academic institution, including semi-structured interviews and direct observations at two preoperative evaluation clinics and one outpatient surgery center.

The teacher’s didactic intervention also requires knowledge and control of learning tasks’ workloads. The objectives of the study were as follows: (i) to quantify the subjective external load-eTL of tasks framed in didactic units designed by in-service teachers; and (ii) to analyze the differences in the subjective eTL according to the game situation and the game space. A total of 306 learning tasks designed by seven in-service teachers (five men and two women), with more than 10 years of teaching practice, were analyzed.

The general objective of this study was to identify the variation in heart rate (HR) of Portuguese skydivers during 6 moments in their first jump of the day, bearing in mind the variable level of experience. Thirty-one Portuguese skydivers, 28 men and 3 women, aged between 19 and 62, participated in the study, 12 had A and B licenses (less experienced) and 19 had C and D licences (more experienced). The instrument used to record the heart rate of the skydivers at the different moments of their first jump of the day was the WIMU PRO.

The load in tasks planned for sports teaching in physical education classes has received little attention. The purpose of this study was therefore to analyze the external load, eTL, in the tasks designed by physical education teachers from the in-service and pre-service stages, for teaching handball in primary education, and to compare them with the tasks included in the lesson plans designed for handball using the tactical games teaching model. An associative, comparative and cross-sectional methodology was used.

The assessment of tactical-technical knowledge of football is essential to develop optimal and integral teaching processes for students. Therefore, the aim of this study was to design and validate an instrument so that teachers, coaches, and researchers can observe and codify both the tactical behaviors and technical skills performed by the students in the game of football. The design and validation of the instrument were carried out in four phases: a) review of the literature and previous instruments; b) design of the Instrument for the Measurement of Learning and Performance in Football (IMLPFoot).
