Objectives: Describe the epidemiological profile and analyze clinical manifestations by age group in chikungunya patients treated in 2015 in a Mérida, Mexico general hospital.

Methods: An observational study describing chikungunya cases recorded by the Department of Epidemiological Surveillance from July to December 2015 and analyzing clinical manifestations by age group. A logistic regression model was used to analyze the association between signs and symptoms and hospital admission.

Results: A total of 830 diagnosed chikungunya cases were treated. Average age was 27.4 ± 17.05 years and the male-to-female ratio was 1:1.4. Most patients came from urban areas (n = 592, 87%) and, in particular, the capital city. Contact with the arthropod vector in the peridomiciliary area was reported in 723 (90%) cases. Muscular and joint impairments were more frequent in the older groups, while rash was more frequent in younger groups. Neurological and non-neurological manifestations of severity did not show greater prevalence in any one age group.

Conclusions: Chikungunya patients had primarily self-limited benign cases, while neurological manifestations such as lethargy, persistent vomiting, hemorrhage, photophobia, and intense headache were predictive of severity and their timely identification in children under 1 year of age was possible through close monitoring.

Background: Acute kidney injury (AKI) is a common complication in hospitalized older patients, associated with increased morbidity, mortality, and health care costs. Major adverse kidney events within 30 days (MAKE30), a composite of death, new renal replacement therapy, or persistent renal dysfunction, has been recommended as a patient-centered endpoint for clinical trials involving AKI.

Objective: This study aimed to develop and validate a machine learning-based model to predict MAKE30 in hospitalized older patients with AKI.

The age estimation of skeletal remains still represents a central issue not only for the reconstruction of the so-called "biological profile," but mostly for the palaeodemographic investigation. This research aims at verifying the feasibility of the adult age estimation method developed on living people by Pinchi et al. (2015 and 2018), for estimating the age at the death of 37 subjects from ancient populations found in two different Italian necropolis of archaeological interest (Mont'e Prama and Florence, X-IX century B.

Purpose: Proliferative vitreoretinopathy (PVR) is the leading cause of surgical failure following rhegmatogenous retinal detachment (RRD). In this study, we aimed to explore ocular and systemic risk factors for PVR due to RRD in a large patient database.

Methods: Patients who have a diagnosis of RRD and PVR, and who have been seen in the last seven years prior to analysis (January 2015-February 2023) were identified in the Vestrum Health database.

Centralized drug procurement is a common practice worldwide to relieve the healthcare burden and promote high-quality development in the pharmaceutical industry. However, scholars have not yet reached an agreement on whether centralized procurement can facilitate the innovation activities of pharmaceutical firms. China's centralized volume-based procurement (CVBP) implemented in 2018 provides an ideal quasi-natural experiment to evaluate the effect of centralized procurement on the R&D investment of the firms.
