Proposal of a prophylactic photobiomodulation protocol for chemotherapy-induced oral and oropharyngeal mucositis: a randomized clinical trial.

Photobiomodulation therapy (PBMT) is widely used in oncology settings, but lack of assessment standardization is the main barrier to optimization of clinical protocols. This study analyzed three PBMT protocols for preventing oral and oropharyngeal mucositis (OM) in patients undergoing chemotherapy (CT) and/or hematopoietic stem cell transplantation (HSCT). This is a preliminary randomized blind clinical trial.

Safety protocols for dental care during the COVID-19 pandemic: the experience of a Brazilian hospital service.

The coronavirus disease (COVID-19) has been prioritized in relation to other illnesses considered critical, such as cancer, cardiovascular diseases/stroke, diabetes, and autoimmune diseases. The management of patients with these diseases involves dental care to reduce systemic complications caused by odontogenic infections, and/or to treat oral manifestations of systemic comorbidities. In this regard, the dental care of these individuals must be guaranteed during the pandemic.

Acute invasive fungal rhinosinusitis in pediatric patients with oncohematological diseases.

Introduction: Invasive fungal diseases represent important causes of morbidity and mortality among pediatric oncohematological patients. Acute invasive fungal rhinosinusitis is a rare and aggressive disease that occurs mainly in immunocompromised patients. The mortality rate is high and therefore, accurate and early diagnosis is essential.

ADVERSE EVENTS RELATED TO MECHANICAL VENTILATION IN A PEDIATRIC INTENSIVE CARE UNIT.

Objective: To identify the prevalence and factors associated with adverse events (AE) related to invasive mechanical ventilation in patients admitted to the Pediatric Intensive Care Unit (PICU) of a tertiary public hospital.

Methods: This is a cross-sectional study from July 2016 to June 2018, with data collected throughout patients' routine care in the unit by the care team. Demographic, clinical and ventilatory characteristics and adverse events were analysed.

Prophylactic photobiomodulation therapy using 660 nm diode laser for oral mucositis in paediatric patients under chemotherapy: 5-year experience from a Brazilian referral service.

The use of photobiomodulation therapy (PBMT) in the prevention of oral mucositis (OM) in paediatric care has increased. In this article, we report data of paediatric oncology/haematopoietic stem cell transplantation (HSCT) patients treated with PBMT to prevent chemotherapy-induced OM. A retrospective study was conducted at a Brazilian referral service.

Acinetobacter baumannii orofacial cellulitis: report of 2 cases.

Acinetobacter baumannii infection of skin and soft tissues is uncommon and usually associated with trauma. The present report describes 2 pediatric cases of cellulitis in the orofacial region, caused by A. baumannii infection with a fatal outcome.

Vertical Transmission of HIV-1 in the Metropolitan Area of Belo Horizonte, Brazil: 2006-2014.

Objective:  To revise HIV-1 vertical transmission (VT) rates in the metropolitan area of Belo Horizonte, Brazil, from January of 2006 to December of 2014.

Methods:  Descriptive study of a prospective cohort of HIV-1-infected pregnant women and their children, monitored by the Maternal and Child HIV/Aids Research Group of Research Group at Faculty of Medicine of Universidade Federal de Minas Gerais, Brazil.

Results:  The VT general rate was 1.

Long-term postpartum adherence to antiretroviral drugs among women in Latin America.

Antiretroviral adherence in the postpartum period is crucial for maternal health and decreasing the risk of mother-to-child HIV transmission and transmission to sexual partners. Self-reported antiretroviral adherence was examined between 6- to 12-weeks and 30 months postpartum among 270 HIV-infected women enrolled in a prospective cohort study from 2008 to 2010 at multiple sites in Latin America. Adherence data were collected at each study visit to quantify the proportion of prescribed antiretrovirals taken during the previous three days, assess the timing of the last missed dose, and identify predictors of adherence.

HIV-1 RNA detection in the amniotic fluid of HIV-infected pregnant women.

This study is aimed at evaluating the potential to detect human immunodeficiency virus (HIV) in amniotic fluid (AF) collected at delivery from 40 HIV-positive pregnant women. Thirty patients had a plasma viral load (VL) below 1,000 copies/mL at delivery. VL was positive in three AF samples.

Predictors of postpartum viral load rebound in a cohort of HIV-infected Brazilian women.

Objective: To assess the postpartum viral load of HIV-infected women treated with potent antiretrovirals (ARVs) during pregnancy, and look for predictors of viral load rebound.

Methods: Of 112 women who took potent ARVs during pregnancy, 60 took them as prophylaxis to prevent mother-to-child transmission of HIV. The remaining 52, who had AIDS, were treated continuously with ARVs before, during, and after pregnancy.

Evaluation of hematological, virologic and anthropometric parameters as progression markers in HIV-1 infected children.

Objective: To analyze total lymphocyte count, total leukocyte count, hemoglobin levels, nutritional status, CD4+ T-lymphocyte count and viral load as markers of disease progression and/or death in HIV-infected children.

Methods: This retrospective cohort study assessed antiretroviral naïve HIV-infected children who were asymptomatic or had mild and/or moderate symptoms. The events of interest were: progression to clinical category C (according to the classification of the Centers for Disease Control and Prevention - CDC, 1994) or death.

Determinants and trends in perinatal human immunodeficiency virus type 1 (HIV-1) transmission in the metropolitan area of Belo Horizonte, Brazil: 1998 - 2005.

Significant decrease in human immunodeficiency virus type 1 (HIV-1) vertical transmission has been observed worldwide in centers where interventions such as antiretroviral therapy (ART), elective cesarean section, and avoidance of breastfeeding have been implemented. This prospective cohort study aimed to assess the determinants of and the temporal trends in HIV-1 vertical transmission in the metropolitan area of Belo Horizonte, Brazil from January 1998 to December 2005. The rate of HIV-1 vertical transmission decreased from 20% in 1998 to 3% in 2005.

Persistence of genotypic resistance to nelfinavir among women exposed to prophylactic antiretroviral therapy during pregnancy.

We assessed the development of drug resistance in women exposed to antiretroviral therapy (ART) for prevention of mother-to-child transmission (PMTCT) after 24 weeks postpartum in a prospective cohort of HIV-1-infected women. HIV-1-infected women, who received prophylactic ART during pregnancy, had genotypic resistance testing performed at the start (T1) of and 24 weeks after ART interruption (T2). The women had CD4 counts >250 cells/ml and no AIDS defining conditions.
