INTRODUCTION: Low back pain (LBP) is a prevalent musculoskeletal disorder with a wide range of etiologies, ranging from self-limiting conditions to life-threatening diseases. Various modalities are available for the diagnosis and management of patients with LBP. However, many of these health services, known as low-value care (LVC), are unnecessary and impose undue financial costs on patients and health systems. The present study aimed to explore the perceptions of service providers regarding the facilitators and barriers to reducing LVC in the management of LBP in Iran...

The human brain functional connectivity network (FCN) is constrained and shaped by the communication processes in the structural connectivity network (SCN). The underlying communication mechanism thus becomes a critical issue for understanding the formation and organization of the FCN. A number of communication models supported by different routing strategies have been proposed, with shortest path (SP), random diffusion (DIF), and spatial navigation (NAV) as the most typical, respectively requiring network global knowledge, local knowledge, and both for path seeking...

BACKGROUND: One needs to choose wisely between primary neoadjuvant chemotherapy and primary cytoreductive surgery in ovarian cancer. The aim was to determine the recurrence free survival and overall survival after surgery for epithelial ovarian cancer and also the risk factors for recurrence and death. METHODS: Electronic medical records of 322 women operated for ovarian, fallopian or primary peritoneal cancer between 2011 and 2015 were reviewed. Descriptive statistics were used to describe patients and their clinical outcomes...

BACKGROUND: According to the United Nations, access to medical care is a fundamental human right. However, there is widespread stigmatization of severe mental illnesses and this appears to seriously hamper the quality of healthcare in people with psychiatric co-morbidity. Thus, interventions that help reduce stigma among healthcare providers are urgently needed. PURPOSE: The objective of the current study was to investigate the effects of a psychiatric clerkship on stigmatizing attitudes toward mental disorders held by medical students...

INTRODUCTION: Guidelines may play an important role in the process of adopting a planetary health perspective in clinical medicine. Current issues relating to the integration of planetary health aspects in guidelines were discussed during a workshop at the German Network for Evidence-Based Medicine conference in 2023. METHODS: In a multidisciplinary workshop, 25 persons with an interest in guideline development selected important planetary health dimensions that could be promptly included in guidelines...

PURPOSE: The purpose of this study was to investigate the impact of the type of data capture on the time and help needed for collecting patient-reported outcomes as well as on the proportion of missing scores. METHODS: In a multinational prospective study, thyroid cancer patients from 17 countries completed a validated questionnaire measuring quality of life. Electronic data capture was compared to the paper-based approach using multivariate logistic regression...

BACKGROUND: ADHD is often described as a disorder of altered reward sensitivity, yet few studies have examined the extent to which: (i) treatments for ADHD impact reward-related mechanisms; and (ii) changes in the reward system are associated with clinical improvement. This study addresses these issues - examining the extent to which clinical improvement following lisdexamfetamine (LDX) treatment is associated with changes in brain reward system activation. METHODS: Twenty adults (M = 11, 55%, F = 9, 45%), ages 19-52 (M = 33...

OBJECTIVE: Examine the frequency and cost of procedural clearance tests and exams in preparation for low-risk cataract surgery among members of a commercial healthcare organization in the US. Determine what characteristics most strongly predict receipt of preoperative care and the probability that preoperative care impacts post-surgical adverse events. DESIGN: Retrospective health care claims analysis and medical records review from a large, blended-health organization headquartered in Western Pennsylvania, USA...

BACKGROUND: Fall prevention alarms are commonly used among US hospitals as a fall prevention strategy despite limited evidence of effectiveness. Further, fall prevention alarms are harmful to healthcare staff (e.g., alarm fatigue) and patients (e.g., sleep disturbance, mobility restriction). There is a need for research to develop and test strategies for reducing use of fall prevention alarms in US hospitals. METHODS: To address this gap, we propose testing the effectiveness and implementation of Alarm with Care, a de-implementation strategy to reduce fall prevention alarm use using a stepped-wedge randomized controlled trial among 30 adult medical or medical surgical units from nonfederal US acute care hospitals...

OBJECTIVES: National societies recommend against performing routine daily laboratory testing without a specific indication. Unnecessary testing can lead to patient harm, such as hospital-acquired anemia. The objective of this study was to reduce repeat complete blood counts (CBCs) after initial testing. METHODS: This was a quality improvement initiative implemented across 11 safety net hospitals in New York City. A best practice advisory (BPA) was implemented that asked the user to remove a CBC if the last 2 CBCs within 72 hours had normal white blood cell and platelet counts and unchanged hemoglobin levels...

INTRODUCTION: Broad-spectrum empiric antibiotics are routinely administered to hospitalized patients with potential infections. These antibiotics provide protection; however, they come with their own negative effects. The utility of Methicillin-resistant Staphylococcus aureus (MRSA) polymerase chain reaction (PCR) nasal screening to steward anti-MRSA empiric antibiotics in hospitalized patients is established. With this current study, we look to determine the optimal frequency of MRSA nasal testing to help limit unnecessary testing consistent with the efforts of Choosing Wisely...

Quantifying the number of molecules from fluorescence microscopy measurements is an important topic in cell biology and medical research. In this work, we present a consecutive algorithm for super-resolution (stimulated emission depletion (STED)) scanning microscopy that provides molecule counts in automatically generated image segments and offers statistical guarantees in form of asymptotic confidence intervals. To this end, we first apply a multiscale scanning procedure on STED microscopy measurements of the sample to obtain a system of significant regions, each of which contains at least one molecule with prescribed uniform probability...

BACKGROUND: Although lipid-lowering drugs are not recommended for primary prevention in patients 75+, prevalence of use is high and there is unexplained variation in prescribing between physicians. The objective of this study was to determine if physician communication ability and clinical competence are associated with prescribing lipid-lowering drugs for primary and secondary prevention. METHODS: We used a cohort of 4,501 international medical graduates, 161,214 U...

A considerable amount of spending in health care is deemed wasteful. Overdiagnosis, i.e. the labelling of a person with a diagnosis that lacks net benefit, is an entity within the overarching concept of »too much medicine«. Overdiagnosis includes overdetection and overdefinition. Disease mongering is a type of overdefinition with economic drivers. Overtesting and overtreatment are other aspects of »too much medicine«, but are not overdiagnosis per se. Medical research tends to focus on benefits of diagnostics and therapy, whereas overdiagnosis and other harms receive less attention, leading to overestimation of benefits...

BACKGROUND: Running on different surfaces, including natural and artificial surfaces, requires different gait mechanics, especially in individuals with foot deformity. RESEARCH QUESTION: How muscle activity change during running on the ground and artificial turf in males with pronated and supinated feet? METHODS: In this quasi-experimental study, we assessed a cohort of young male subjects, classified as healthy (n = 10), and with pronated (n = 10) or supinated (n = 10) feet...

BACKGROUND: A key step for comparative genomics is to group open reading frames into functionally and evolutionarily meaningful gene clusters. Gene clustering is complicated by intraspecific duplications and horizontal gene transfers that are frequent in prokaryotes. In consequence, gene clustering methods must deal with a trade-off between identifying vertically transmitted representatives of multicopy gene families, which are recognizable by synteny conservation, and retrieving complete sets of species-level orthologs...
