The COVID-19 health emergency: the influence of the Human Development Index on the reorganization of primary care.

Objective: This study aimed to analyze and compare the organization and care offered by Primary Health Care (PHC) to people with suspected and/or diagnosed COVID-19 in Brazilian municipalities, considering the Human Development Index (HDI).

Methods: This is an analytical cross-sectional study carried out with managers of PHC services in Brazilian municipalities. The data were collected using a self-administered questionnaire via Google Forms between April and September 2022 and were analyzed using prevalence ratios, using a Poisson regression model with a random effect and a 5% significance level.

Multi-colour reflective metagrating with neutral transparency for augmented reality.

This paper presents the design and experimental validation of an all-dielectric and transparent metagrating-based metalens. Leveraging multiple guided mode resonances simultaneously, the metagrating enables the generation of two or more spectrally narrow reflection peaks. These peaks are achieved through the precise engineering of guided mode resonances, allowing for the reflection of a comb of vibrant and saturated colours.

Stone Babies: A Pictorial Essay With Insights From 25 Museal Lithopaedions.

Background: Lithopaedion, or "stone baby," represents an exceptionally rare clinical phenomenon with fewer than 350 documented cases existing in the medical literature. This condition arises when an advanced extrauterine pregnancy ceases its developmental trajectory and undergoes a lithification process, potentially resulting in a calcified mass with fetal-like morphology. Typically, lithopaedions remain asymptomatic for decades, but may occasionally elicit acute symptoms necessitating medical intervention.

Blood-Based FTIR Spectroscopy as a Minimally Invasive Diagnostic Method for Colorectal Cancer: A Meta-Analysis.

Objective: This meta-analysis aims to pool the results of existing studies to obtain more precise estimates on the diagnostic efficiency of the Fourier transform infrared (FTIR) spectroscopy in detecting CRC using blood-based samples.

Methods: A comprehensive database search identified 4,931 studies that were screened for eligibility. Relevant data were then extracted and collated and analyzed using Meta-DiSc 1.
