The accuracy of commercially available tests for COVID-19 in Brazil remains unclear. We aimed to perform a meta-analysis to describe the accuracy of available tests to detect COVID-19 in Brazil. We searched at the Brazilian Health Regulatory Agency (ANVISA) online platform to describe the pooled sensitivity (Se), specificity (Sp), diagnostic odds ratio (DOR) and summary receiver operating characteristic curves (SROC) for detection of IgM/IgG antibodies and for tests using naso/oropharyngeal swabs in the random-effects models. We identified 16 tests registered, mostly rapid-tests. Pooled diagnostic accuracy measures [95%CI] were: (i) for IgM antibodies Se=82% [76-87]; Sp=97% [96-98]; DOR=168 [92-305] and SROC=0.98 [0.96-0.99]; (ii) for IgG antibodies Se=97% [90-99]; Sp=98% [97-99]; DOR=1994 [385-10334] and SROC=0.99 [0.98-1.00]; and (iii) for detection of SARS-CoV-2 by antigen or

Background: Oral health-related quality of life (OHRQoL) measures are being increasingly used to introduce dimensions excluded by normative measures. Consequently, there is a need for an index which evaluates children's OHRQoL validated for Brazilian population, useful for oral health needs assessments and for the evaluation of oral health programs, services and technologies. The aim of this study was to do a cross-cultural adaptation of the Child Oral Impacts on Daily Performances (Child-OIDP) index, and assess its reliability and validity for application among Brazilian children between the ages of eleven and fourteen.

It can be concluded that there is an association between dental caries experience and the Child-OIDP index. This association indicates the impact of this condition on the quality of life of school children. Moreover, the Child-OIDP index is explained more by self-reported oral problems than by clinical normative measures.

Mucormycosis is a life-threatening infection in HIV patients and clinician should be aware of this co-infection in the differential diagnosis of HIV opportunistic infections.

Oral care is frequently suboptimal in children from developing countries, especially those suffering from severe systemic diseases. The aim of the present study was to analyze the oral epidemiological profile of 3-to-5-year-old children with congenital heart disease. Dental and medical records of children evaluated at the Dental Service of the National Institute of Cardiology, Rio de Janeiro, Brazil, were reviewed. Caries experience was reported using the dmft index. Negative behavior towards dental management was recorded. The sample consisted of 144 children aged 4.41 ± 0.95 years. The mean dmft value was 5.4 ± 4.9, and 80.5% had at least one caries lesion. Dmft index was greater in the presence of cyanotic cardiac disease and in children with negative behavior. An increase in the "missing" component of the dmft index was also found in children using medicine on a daily basis. A higher caries experience was associated with children whose fathers had only an elementary education. In conclusion, children with congenital heart disease had high levels of caries experience at a young age. Cyanosis, negative behavior, daily use of medicine, one-parent family and the educational level of fathers seem to influence caries experience in children with congenital cardiac disease.

Transient elastography (TE) based on liver stiffness measurement (LSM) is one of the most validated noninvasive methods for liver fibrosis staging in patients with chronic liver diseases. This method is painless, has no potential complications, is rapid (<10 min), and can be performed at the patient's bedside. However, several points should be considered when interpreting TE results. This review aims to discuss the critical points that might influence liver stiffness and TE results. Spectrum bias and the impact of the prevalence of fibrosis stages should be taken into account when interpreting the studies that validated this method using liver biopsy as a gold-standard. LSM might be influenced by nonfasting status, flare of transaminases, heart failure, extrahepatic cholestasis, presence of steatosis, aetiology of liver disease, type and position of probe, and operator's experience. In addition, interobserver variability can impact on the management of patients with chronic liver diseases. TE should be performed by an experienced operator (>100 exams), in a 3-hour fasting status, and its results should be handled by specialist clinicians that are aware of the limitations of this method.
