Background And Objectives: In the literature, the references on adverse reactions to latex products have been significantly increasing for the last few years. However, it lacks Brazilian data regarding the prevalence of latex-related sensitization in health care workers. The objective of this study was to evaluate the prevalence of signs and symptoms suggestive of latex-related sensitization in health care workers.
Methods: Upon approval by the Ethics Committee it were selected a population of subjects from the Institution's departmental workforce: the Surgical Center Cleaning, Accounting and Nursing personnel and the physicians working at the Surgery, Gynecology, Obstetrics, Anesthesiology, Intensive Care Unit and Medical Clinics. After the informed consent has been obtained, the subjects were submitted to a questionnaire on: age, gender, professional category; type and length of time in contact with latex products; type of gloves; signs/symptoms suggestive of latex-related sensitization (LS) in and out of the hospital environment; signs/symptoms suggestive of atopy and food allergy.
Results: A total of 326 questionnaires were evaluated (193 women and 133 men, aged between 30 and 73 years old). Out of this total, 75% of interviewees had up to 10-year length of service in their professions. The prevalence of signs/symptoms suggestive of sensitization to latex in the hospital environment, between the group of employees working in the Accounting Sector (therefore not exposed to latex in the workplace) and the remaining employees (exposed to latex products in their working environment) was significantly different (p<0.001). Also, the percentage of signs/symptoms suggestive of LS in the hospital environment was higher in subjects showing higher average time of use of gloves per day.
Conclusions: The present study demonstrated higher prevalence of signs/symptoms suggestive of LS among those workers exposed to latex products in the hospital environment and with higher contact time with any type of gloves. Therefore, it is clear the need to proceed with this research, for laboratorial confirmation of the latex-related sensitization, as well as that a proposal be submitted to the Institution towards the adoption of preventive measures regarding latex-related sensitization issue. Also, a consensus must exist to the fact that the health care workers comprise a population in risk for allergy to latex products.

The interaction between major depressive disorder (MDD) and overweight/obesity has received considerable attention owing to its widespread occurrence and the intricate biopsychological implications involved. Despite extensive research, the neural mechanisms underlying these comorbid conditions, particularly in terms of functional network connectivity (FNC), are still not well understood. This study aimed to clarify these mechanisms by utilizing resting-state functional magnetic resonance imaging (rs-fMRI) to examine both static and dynamic FNC.

Background: To investigate corneal higher-order aberrations (HOAs) and choroidal characteristics in myopic individuals and explore the association between HOAs and choroidal parameters.
Methods: Myopic participants were categorized into three groups based on axial lengths (ALs). We compared corneal HOAs, including spherical (Z), comatic (Z and Z), and trefoil (Z and Z) aberrations, as well as choroidal vascularity index (CVI) and choroidal thickness (CT).

Article Synopsis
- The study aimed to measure choroidal thickness in adults who underwent childhood atropine treatment for myopia using a deep learning segmentation method.
- It found that 77.7% of the participants received atropine, which was linked to a choroid thickness increase of 20-40 μm in specific regions of the eye, after accounting for age and sex.
- The research also indicated a relationship between greater central choroidal thickness and a lower incidence of tessellated fundus, implying childhood atropine exposure may have lasting effects on eye structure.
Background: Although crackles on chest auscultation represent a fundamental component of the diagnostic suspect for fibrotic interstitial lung disease (ILD), their reliability has not been properly studied. We assessed the agreement among respiratory physicians on the presence and changes over time of audible crackles collected in a prospective longitudinal cohort of patients with fibrotic ILD.
Methods: Lung sounds were digitally recorded at baseline and after 12 months at eight anatomical sites.

Purpose: This study presents a novel, three-dimensional method for measuring the tilt angle of the tilted optic disc (TOD) using spectral-domain optical coherence tomography (SD-OCT) and investigates the correlation between ocular-related parameters and TOD.
Methods: We included the right eyes of 243 healthy young individuals, categorized by axial length. We measured the ovality index (OI) and dihedral angle (DA) using SD-OCT infrared ray fundus photographs and high-resolution cross-sectional images of the optic disc, respectively.
