Background COVID-19 is still a global challenge in regard for management and therapy. Pulmonary embolism (PE) seems to have a higher prevalence in COVID-19 instead of non-COVID patients. Clinical and laboratory parameters related with PE are still unknown. Methods We conducted a retrospective unicentre study in Alto Vicentino Hospital between March 1st, 2020, and January 31st, 2021 in patients admitted for COVID-19 tested with a RT-PCR nasal swab. Data about patients studied with computed tomography pulmonary angiogram (CTPA) because of PE suspicion were collected, as their clinical and laboratory parameters too. Results 2621 patients were admitted for COVID-19 in Alto Vicentino Hospital between March 1st, 2020, and January 31st, 2021 and in 267 of them a CTPA was performed finding 50 PE (18.7%). Only non-Caucasian race (OR = 5.44; 95% CI 1.22–24.35; p = 0.027) and previous VTE (OR = 5.3; 95% CI 1.09–26.17; p = 0.039) were found to be independently associated with PE. Conclusion PE is a frequent complication of COVID-19 and clinician need high degree of suspicion because clinical and laboratoristic parameters cannot drive diagnosis.

Oral health care is fundamental to preserve the individual integrity and consequently influences the general health. This observational, cross-sectional and analytical study evaluated the oral condition of 129 intellectually disabled individuals from the Association of Parents and Friends of Exceptional Children (APAE) in three southern Brazilian cities. Dental caries (DMFT and dmft indices) and periodontal disease (PSR index) were evaluated considering the intellectual disability level. A questionnaire on socioeconomic status (income and education level) and the last visit to a dentist was answered by the subjects' parents/guardians. The data were statistically evaluated using analysis of variance (ANOVA) and Tukey test (α=0.05). The mean DMFT values were 2.27, 3.76 and 0.58 (p<0.05), and the mean dmft values were 1.48, 1.55 and 2.75, respectively for subjects with mild, moderate and severe disabilities. Regarding the PSR index, 43% of the subjects presented gingivitis without retention factor (no calculus or defective margins) with no significant differences among the three disability levels. Considering the population and the limitations of this study, the subjects presenting severe disabilities showed significantly lower mean DMFT values compared to other disability levels, probably because the caretakers are responsible for the oral hygiene of such subjects.

Aim: Type 2 diabetes mellitus (DM2) is a chronic disease caused by the underproduction of insulin in the organism and it is considered a risk factor to periodontal disease. Materials and methods:This study performed a cross-sectional research on the main oral changes in patients with DM2 and nondiabetics, in Passo Fundo, Rio Grande do Sul, Brazil. The sample included 116 patients examined at the Diabetes Outpatient Clinic of the School of Medicine of the University of Passo Fundo (UPF) and 134 nondiabetic patients examined at the Examinations, Triage, and Emergency Sector of the School of Dentistry of UPF. Inclusion criteria for the study were patients over 35-years old, diagnosed with DM2 for more than 2 years. The same criteria were used for the control group, except for the presence of diabetes. Data collected were analyzed by Statistical Package for the Social Sciences 18.0 for Windows™ software and the Chi-square test at 5% significance. This study showed that, overall, oral lesions were more prevalent in diabetic patients. Results:The stomatological manifestations observed more frequently in such patients were pseudomembranous candidiasis, lichen planus, lingual varices, xerostomia, and prosthetic stomatitis (p > 0.001). Conclusion:Therefore, based on the sample investigated, it is concluded that patients with DM2 present higher prevalence of oral lesions when compared with nondiabetics.
