Analyzing and Mitigating the Risks of Patient Harm During Operating Room to Intensive Care Unit Patient Handoffs.

Background: Patients continue to suffer from preventable harm and uneven quality outcomes. Reliable clinical outcomes depend on the quality of robust administrative systems and reliable support processes. Critically ill patient handoffs from the operating room to the intensive care unit are known high-risk events.

Impact of the COVID-19 pandemic on the severity of newly diagnosed cases of head and neck cancer in southern Brazil.

This observational study aimed retrospectively assess the impact of the COVID-19 pandemic on the head and neck squamous cell carcinoma (HNSCC) diagnosis and severity of the disease in southern Brazil. All new cases diagnosed with HNSCC from March 11, 2019 to March 10, 2020 (pre-COVID-19) and from March 11, 2020 to March 10, 2021 (COVID-19) were included. The data collected were: date of the histopathological diagnosis, sociodemographic data, place of residence, data related to the tumor (location of the primary tumor, lymph node involvement, distant metastasis and TNM clinical staging), time elapsed between the diagnosis and treatment initiation.

Individual- and City-Level Socioeconomic Factors and Tooth Loss among Elderly People: A Cross-Level Multilevel Analysis.

This study aimed to test the association of contextual and individual socioeconomic status with tooth loss among Brazilian elderly people aged 65-74 years. Data from 5435 elderly participants from the Brazilian National Oral Health Survey (2010) were linked to city-level data for 27 state capitals and the Federal District. Tooth loss was clinically assessed according to the number of missing natural teeth.

Effect of quercetin on E-NTPDase/E-ADA activities and cytokine secretion of complete Freund adjuvant-induced arthritic rats.

The effect of quercetin was assessed in rats induced with complete Freund adjuvant (CFA). Arthritis scores, paw oedema, latency, activities of myeloperoxidase (MPO), ectonucleoside triphosphate diphosphohydrolase (E-NTPDase), and ectoadenosine deaminase (E-ADA) in lymphocytes were determined. Furthermore, nucleotide and nucleoside levels as well as the secretion of pro- and anti-inflammatory cytokines were evaluated.

Contextual and individual determinants of non-utilization of dental services among Brazilian adults.

Objectives: To examine the association of contextual and individual determinants with non-utilization of dental services among Brazilian adults.

Methods: Data were from adults aged 35-44 years (N = 7,265) from the 2010 Brazilian Oral Health Survey (SB Brasil Project). Non-utilization of dental services was assessed whether the individual has never had a dental visit over the whole life time.

Ameliorative effect of black grape juice on systemic alterations and mandibular osteoradionecrosis induced by whole brain irradiation in rats.

Purpose: Whole brain irradiation (WBI) causes a variety of secondary side-effects including anorexia and bone necrosis. We evaluated the radiomodifying effect of black grape juice (BGJ) on WBI alterations in rats measuring food and water intake, body weight, hemogram, and morphological and histological mandibular parameters.

Materials And Methods: Forty male rats (200-250 g) were exposed to eight sessions of cranial X-ray irradiation.

Free and nanoencapsulated vitamin D3 : effects on E-NTPDase and E-ADA activities in an animal model with induced arthritis.

Unlabelled: The effect of vitamin D3 in oral solution (VD3 ) and vitamin D3 -loaded nanocapsules (NC-VD3 ) was analysed in animals with complete Freund's adjuvant (CFA) induced arthritis (AR). For this purpose, we evaluated scores for arthritis, thermal hyperalgesia and paw oedema, as well as histological analyses and measurements of the activity of the ectonucleoside triphosphate diphosphohydrolase (E-NTPDase) and ecto-adenosine deaminase (E-ADA) enzymes in rat lymphocytes. Haematological and biochemical parameters were also determined.

An experimental model of contact dermatitis: evaluation of the oxidative profile of Wistar rats treated with free and nanoencapsulated clobetasol.

Objective: An experimental animal model of contact dermatitis (CD) was used to investigate the effects of free and nanoencapsulated clobetasol propionate on the skin and on the oxidative profile of liver tissue.

Methods: Female Wistar rats were divided into six groups, each containing eight rats. The first group, control (C), was sensitized with solid vaseline.
