The Impact of the COVID-19 Pandemic on the Mental Health of Teachers and Its Possible Risk Factors: A Systematic Review.

(1) Objective: The objective was to analyze the development of psychiatric pathologies/burnout syndrome and their possible risk factors in teachers in the context of the COVID-19 pandemic. (2) Methods: A qualitative systematic review was carried out, according to the PRISMA protocol, in the PubMed, Scopus, and Web of Science databases using a combination of the following descriptors [MeSH]: "mental health", "mental disorders'', "covid-19" and "school teachers''. Articles selected were written in English, Portuguese and Spanish, published between November 2019 and December 2022. (3) Results: The most common psychiatric pathologies were generalized anxiety disorders and depression. Burnout syndrome was also quite prevalent. Of the 776 articles identified, 42 were selected after applying the eligibility criteria. Although there is variability among the analyzed studies, the risk factors most correlated with increased morbidity in teachers were: (i) being female; (ii) age below the fifth decade of life; (iii) pre-existence of chronic or psychiatric illnesses before the pandemic; (iv) difficulty in adapting to the distance education model; (v) family/work conflicts; (vi) negative symptoms caused by the pandemic. (4) Conclusions: Therefore, the COVID-19 impact on mental health appears to be more common in female teachers in their fifth decade of life and with pre-existing psychiatric comorbidities. However, prospective studies are needed to better map this situation.

Traumatic dental injuries and their sequelae in visually impaired adolescents.

BACKGROUND/AIM: Traumatic dental injuries are a public health problem. Visual impairment can be considered a risk factor for traumatic dental injury given the difficulties imposed upon visually impaired patients by limited physical perception. The aim of this study was to evaluate the frequency of traumatic dental injuries and their sequelae in adolescents with visual impairment. MATERIAL AND METHODS: Adolescents (12-18 years) with visual impairment (blind or low vision) and no other special needs were included in the study. Data were collected after a clinical and radiographic examination. Data regarding gender, age, type of visual impairment, site of traumatic dental injury, tooth type, and affected tissues, care, and sequelae were obtained. The data were analyzed descriptively and with the chi-square test (p < .05). RESULTS: Among 96 adolescents (65% blind; 55% female), 20.8% (n = 20) reported they had previously experienced a traumatic dental injury of 33 teeth (78.8% maxillary central incisors). Combined injuries (30.3%; n = 10) were the most common traumatic dental injuries, followed by concussion (27.3%, n = 9) and enamel-dentine fractures (21.2%, n = 7). Sequelae were observed in 27.3% (n = 9) of the teeth affected by a traumatic dental injury, and apical periodontitis (77.8%, n = 7) was the most common. CONCLUSION: The frequency of traumatic dental injuries among visually impaired adolescents can be considered high, and the observed sequelae could have been minimized if adequate clinical and radiographic follow up had been carried out. These results suggest the importance of enhanced educational efforts to reduce traumatic dental injuries.

The role of inflammation in adipocytolytic nonsurgical esthetic procedures for body contouring.

BACKGROUND: The adipocytolytic non-surgical esthetic procedures are indicated for the reduction of localized fat and are effective in reducing local adiposity through the ablation of adipocytes with fast and lasting results, besides causing local inflammation. OBJECTIVE: This study aimed to characterize the adipocytolytic procedures and correlate the phases of the inflammatory process with the results obtained from such procedures, in order to clarify the role of inflammation triggered by the adipocytolytic procedures and its relation with the lipolytic process, with a focus on body shaping. METHODS: This work is an integrative literature review that presents a total of 72 articles published between 1998 and 2015, derived from the PubMed database, in order to establish a relationship between clinical and basic science research, assuming an important role in medical practice based on evidence. RESULTS: The results show that the adipocytolytic procedures are characterized by triggering inflammation arising from the disruption of adipocytes by interfering with the lipolytic signaling pathways in both acute and chronic phases of inflammation through the direct action of proinflammatory cytokines or catecholamines. Therefore, inflammation plays an important role in modulating the lipolytic process, influencing body shaping. CONCLUSION: The inflammatory process assists the adipolytic process in all stages of inflammation, contributing to the reduction of body contouring.
