Aims: The aim of this systematic review was to explore and evaluate the efficacy of interventions to reduce the prevalence of look-alike, sound-alike (LASA) medication name errors.

Methods: We conducted a systematic review of the literature, searching PubMed, EMBASE, Scopus and Web of Science up to December 2016, and re-ran the search in February 2020 for later results. We included studies of interventions to reduce LASA errors and included randomized controlled trials, controlled before-and-after studies, and interrupted time series. Details were registered in Prospero (ID: CRD42016048198).

Results: We identified six studies that fulfilled our inclusion criteria. All were conducted in laboratories. Given the diversity in the included studies, we did not conduct a meta-analysis and instead report the findings narratively. The only intervention explored in RCTs was capitalization of selected letters ("Tall Man"), for which we found limited efficacy and no consensus.

Conclusions: Tall Man lettering is a marginally effective intervention to reduce LASA errors, with a number of caveats. We suggest that Tall Man gives rise to a "quasi-placebo effect", whereby a user derives more benefit from Tall Man lettering if they are aware of its purpose.

Effects of time-of-day on the noradrenaline, adrenaline, cortisol and blood lipidome response to an ice bath.

Sci Rep

January 2025

Professorship of Exercise Biology, Department Health and Sport Sciences, TUM School of Medicine and Health, Technical University of Munich, Munich, Germany.

While the effect of time-of-day (morning versus evening) on hormones, lipids and lipolysis has been studied in relation to meals and exercise, there are no studies that have investigated the effects of time-of-day on ice bath induced hormone and lipidome responses. In this crossover-designed study, a group of six women and six men, 26 ± 5 years old, 176 ± 7 cm tall, weighing 75 ± 10 kg, and a BMI of 23 ± 2 kg/mhad an ice bath (8-12 °C for 5 min) both in the morning and evening on separate days. Absence from intense physical exercise, nutrient intake and meal order was standardized in the 24 h prior the ice baths to account for confounders such as diet or exercise.

Bone Disease Associated with Inactivating Aromatase Mutations and its Management.

Calcif Tissue Int

January 2025

Department of Medicine, Surgery and Neurosciences, University of Siena, Policlinico Santa Maria Alle Scotte, Siena, Italy.

Article Synopsis
  • Aromatase deficiency is a rare genetic disorder caused by mutations in the CYP19A1 gene, affecting both males and females, with an incidence of less than 1 in 1,000,000.
  • In females, symptoms typically present at birth or in early infancy, focusing on sexual development, while in males, issues usually emerge during or after puberty, leading to delayed diagnosis.
  • The paper reviews the skeletal and extraskeletal effects of the condition and discusses strategies for managing bone health in individuals with these mutations.

Background: Understanding optimal prosthesis alignment in TKA remains crucial despite ongoing debate. While current research focuses on osteoarthritic knees, a gap exists in characterizing healthy young adult knees in Asians. This study aims to fill this gap by identifying the distribution of CPAK phenotypes in this population, including potential gender variations and individual differences.

Cystadenocarcinoma is a malignant tumor that has undergone various classifications due to its wide variety of pathological forms since the World Health Organization (WHO) classification in 2005. We present a case involving a 72-year-old man who reported pain and swelling in the left floor of his mouth during eating. Examination demonstrated a thumb-sized, mobile mass with elastic softness.

Article Synopsis
  • Adolphe Quetelet's 1835 work provided a mathematical analysis showing that body weight is approximately proportional to height in adults, a concept that later evolved into what we now call body mass index (BMI).
  • BMI has become a global standard for assessing body fatness at both individual and population levels, evolving through extensive scientific discourse.
  • The rise of effective weight loss treatments has sparked renewed examination of BMI's origins and its appropriateness for diagnosing obesity, emphasizing the importance of understanding its historical and mathematical basis for students and practitioners in health fields.
