A proposal in Brazil to use generative AI in education threatens quality and equity.

Artificial intelligence (AI) is considered one of the most revolutionary technological developments today. But can it replace teachers in education? A new proposal in São Paulo, Brazil, suggests this might be possible, but it raises significant concerns about educational quality and equity.

Large-scale sea ice-Surface temperature variability linked to Atlantic meridional overturning circulation.

Due to its involvement in numerous feedbacks, sea ice plays a crucial role not only for polar climate but also at global scale. We analyse state-of-the-art observed, reconstructed, and modelled sea-ice concentration (SIC) together with sea surface temperature (SST) to disentangle the influence of different forcing factors on the variability of these coupled fields. Canonical Correlation Analysis provides distinct pairs of coupled Arctic SIC-Atlantic SST variability which are linked to prominent oceanic and atmospheric modes of variability over the period 1854-2017.

Correlation of periodontal and microbiological evaluations, with serum levels of estradiol and progesterone, during different trimesters of gestation.

Our purpouse was to identify quantitatively and qualitatively the subgingival flora in different gestational trimesters, compared to non-pregnant women; evaluating the correlations between epidemiological characteristics, clinical diagnosis, microbiological findings and levels of estradiol and progesterone. 52 pregnant women divided into 3 groups, according to the gestational trimester and 15 non-pregnant patients, without hormonal contraceptives, were evaluated. Plaque index (PI), gingival index (GI), probing depth (PD) and clinical attachment level (CAL) were evaluated.

Reduced functional capacity of community-dwelling elderly: a longitudinal study.

This study aimed to identify the incidence and risk factors for the reduced functional capacity of community-dwelling elderly. A prospective, two-stage cohort study was conducted in 2011 and 2014. The study population consisted of 202 initially independent older adults for the basic activities of daily living.

Caries Experience and Periodontal Status in Children and Adolescents with Cleft Lip and Palate.

Purpose: The purpose of this study was to examine the rate of dental caries and the periodontal status of children and adolescents with cleft lip and palate (CLP) and to compare them with gender- and age-matched control subjects.

Methods: A total of 156 five- to 18-year-olds, with or without CLP, were examined for dental caries (decayed, missing and filled permanent teeth and primary surfaces [DMFT and dmfs, respectively] indices), plaque index (PI), the gingival bleeding index (BI), clinical attachment level (CAL), and probing pocket depth (PPD). Diagnoses of gingivitis (localized and generalized) and periodontitis (mild, moderate, and advanced) were performed.

Periodontal and Microbiological Profile of Intensive Care Unit Inpatients.

Introduction: The bidirectional relationship between the periodontal diseases and systemic diseases was attributed to the focal infection concept. The aims of this study were to assess the periodontal and microbiological profile of intensive care unit (ICU) inpatients submitted to orotracheal intubation, and classify them regarding gender, age group, ethnic, hospitalization reason and period, nosocomial infection occurrence, and death.

Materials And Methods: Inpatients were assessed, distributed into toothed and toothless groups.

Trigger factors in migraine patients.

Background: Migraine is a chronic neurological disease with several trigger factors, including dietary, hormonal and environmental factors.

Purpose: To analyse precipitating factors in a sample of migraine patients.

Method: Two hundred consecutive migraine patients were interviewed about possible trigger factors for migraine attacks.
