Medicinal waste due to improper handling of unwanted medicines creates health and environmental risks. However, the re-dispensing of unused prescribed medicines from patients seems to be accepted by stakeholders when quality and safety requirements are met. Reusing dispensed medicines may help reduce waste, but a comprehensive validation method is not generally available. The design of a novel digital time temperature and humidity indicator based on an Internet of Pharmaceutical Things concept is proposed to facilitate the validation, and a prototype is presented using smart sensors with cloud connectivity acting as the key technology for verifying and enabling the reuse of returned medicines. Deficiency of existing technologies is evaluated based on the results of this development, and recommendations for future research are suggested.

Background: Neuropilin-1 (NRP1) is a transmembrane protein involved in surface receptor complexes for a variety of extracellular signals. NRP1 expression in human cancers is associated with prominent angiogenesis and advanced progression stage. However, the molecular mechanisms underlying NRP1 activity in the tumor microenvironment remain unclear.

Graduate School of Public Health, St Luke's International University, Tokyo, Japan.
Background: Recent studies revealed an association between small kidney volume and progression of kidney dysfunction in particular settings such as kidney transplantation and transcatheter aortic valve implantation. We hypothesized that kidney volume was associated with the incidence of kidney-related adverse outcomes such as worsening renal function (WRF) in patients with acute heart failure (AHF).
Methods: This study was a single-center retrospective cohort study.
First study confirming the transmission of Trypanosoma vivax in cattle through rectal palpation: how many animals can be infected by reusing the same procedure glove, and what role does iodine play as a disinfectant?

The aim of this study was to investigate whether Trypanosoma vivax is transmitted via rectal palpation in cattle, using the same glove with different blood scores, from an animal with an acute infection of this protozoan. In addition, the efficacy of iodine as disinfectant, together with water with or without the presence of feces, to prevent the transmission of T. vivax in cattle during the rectal palpation process was evaluated in the laboratory and animals.

Purpose: To investigate the risk factors for late postoperative pancreatic fistula (POPF) following pancreaticoduodenectomy (PD), with a focus on positive drain fluid culture (DFC) results on postoperative day (POD) 1.
Methods: Medical records of 198 patients who underwent PD with drain fluid amylase (DFA) on POD 5 < 3x upper limit of normal (ULN) were included. Late POPF was defined as POPF diagnosed post-POD 6, with DFA on POD 5 < 3xULN.
Childhood BMI trajectories and sociodemographic factors in an Italian pediatric population.

Unit of Biostatistics, Epidemiology and Public Health, Department of Cardio-Thoraco- Vascular Sciences and Public Health, University of Padua, Padua, Italy.
Childhood obesity is a growing global concern due to its long-term health consequences. Yet, more research relying on multiple time-point BMI measurements is warranted to gain further insight into obesity's temporal trends. We aimed to identify BMI trajectories in children aged 2-10 years and evaluate their association with sociodemographic factors.
