Comparative cohort analysis of pressure ulcer/injury in intensive care unit patients before and during the COVID-19 pandemic.

COVID-19 has emerged as a global pandemic leading to an increase in hospitalization and intensive care unit (ICU) admissions worldwide. Due to severe acute respiratory distress syndrome (ARDS), many patients require prone positioning, which is associated with increased pressure ulcer/injury (PU/PI) incidence. COVID-19 pathophysiology may favor the occurrence of PU/PI due to hypoxemia, inflammatory status, and vasculopathy. This study aimed to compare the incidence of PU/PI in ICU patients before and during the COVID-19 pandemic. A retrospective cohort study was conducted at a university hospital in Brazil. Data from the medical charts of every adult patient admitted to ICU from March to July 2019 and the same period in 2020 were collected. The group from 2019 included 408 patients admitted due to multiple causes, and the group from 2020 included 229 patients admitted due to COVID-19 infection. The incidence of PU/PI was significantly higher in patients admitted in 2020 compared to 2019 (62,5 vs. 33,8%, respectively). Also, PU/PI location and severity have been different between groups, with the patients with COVID-19 (2020 group) more exposed to stage 3, 4, and non-stageable lesions, as well as more PU/PI on face skin and other less common locations. In conclusion, the COVID-19 pandemic has highlighted a higher PU/PI incidence. ICU patients were older during the pandemic, had higher body mass index and comorbidities, and needed more invasive medical devices and pronation. The occurrence of PU/PI was also associated with prolonged hospitalization and mortality.

Intradermal methylene blue administration on the progression of burn injuries.

OBJECTIVE: A burn injury has two defined areas: central necrosis and an adjacent area of ischaemia, which may or may not progress to necrosis. The concentration of nitric oxide (NO) increases after burn injury and may originate from potent oxidising agents. Methylene blue (MB) may act as an antioxidant and is supposed to reduce burn progression. This investigation was carried out to evaluate the effects of intradermal MB on necrosis progression in burns. METHODS: Full-thickness burn injuries were performed by applying a heated metal comb on the shaved back of male Wistar rats. The animals were divided into three groups: Control (C, n=7); MB (2mg/kg) one hour after burn injury (MB1h, n=11); and MB (2mg/kg) six hours after burn injury (MB6h, n=8). After seven days the lesions were photographed for visual assessment of burn necrosis; full-thickness cuts of lesions were dyed with Masson and Giemsa for microscopic histopathology; and tissue fragments of unburned interspaces were processed for chemiluminescence with nitrite/nitrate (NOX) and malondialdehyde (MDA) as oxidative stress markers. RESULTS: No statistically significant differences between groups were observed during visual analysis and NOX dosage. However, in microscopic analysis, the MB1h and MB6h groups showed smaller areas of necrosis, less inflammatory infiltration, and a more significant extension of interspaces. Furthermore, the dosage of MDA revealed that the MB1h group showed lower values when compared with the control group (p=0.001). CONCLUSIONS: The study provided good evidence that MB intradermal injection can reduce necrosis progression in ischaemic perilesional areas and suggests an alternative to treating burns.

Open versus minimally invasive percutaneous surgery for surgical treatment of thoracolumbar spine fractures- a multicenter randomized controlled trial: study protocol.

BACKGROUND: Thoracolumbar fractures are most frequent along the spine, and surgical treatment is indicated for unstable fractures. Percutaneous minimally invasive surgery was introduced to reduce the pain associated with the open posterior approach and reduce the morbidity of the procedure by avoiding damage and dissection of the paravertebral muscles. The goal of this study is to compare the surgical treatment of fractures of the thoracolumbar spine treated by the conventional open approach and the percutaneous minimally invasive approach using similar types of pedicle spine fixation systems. METHODS/DESIGNS: This study is designed as a multi-center, randomized controlled trial of patients aged 18-65 years who are scheduled to undergo surgical posterior fixation. Treatment by the conventional open approach or percutaneous minimally invasive approach will be randomly assigned. The primary outcome measure is postoperative pain, which will be measured using the visual analogue scale (VAS). The secondary outcome parameters are intraoperative bleeding, postoperative drainage, surgery time, length of hospital stay, SF-36, EQ-5D-5 l, HADS, pain medication, deambulation after surgery, intraoperative fluoroscopy time, vertebral segment kyphosis, fracture vertebral body height, compression of the vertebral canal, accuracy of the pedicle screws, and breakage or release of the implants. Patient will be followed up for 1, 2, 3, 6, 12 and 24 months postoperatively and evaluated according to the outcomes using clinical and radiological examinations, plain radiographs and computed tomografy (CT). DISCUSSION: Surgical treatment of thoracolumbar fractures by the open or percutaneous minimally invasive approach will be compared in a multicenter randomized study using similar types of fixation systems, and the results will be evaluated according to clinical and radiological parameters at 1, 2, 3, 6, 12 and 24 months of follow-up. TRIAL REGISTRATION: ClinicalTrial.gov approval number: 1.933.631, code: NCT03316703 in may 2017.

Obesidade na infância / Childhood obesity

A obesidade infantil duplicou entre crianças nos últimos 30 anos e, consequentemente, é hoje um grande problema de saúde pública em todo o mundo. Crianças e adolescentes obesos estão sob maior risco de serem também obesos na vida adulta e por isso, mais predispostos a fatores de risco para doenças cardiovasculares, cerebrovasculares, metabólicas, osteoarticulares, além de transtornos emocionais e psicossociais. Apesar de não haver tratamento específico para a obesidade não orgânica na infância, medidas preventivas, como mudanças no estilo de vida, com a realização de atividades físicas e hábitos alimentares saudáveis, são sabidamente efetivas na redução do peso corporal e do risco de desenvolvimento das doenças relacionadas; no entanto, na prática diária observam-se dificuldades na adoção e aderência a essas medidas. Este artigo faz uma revisão sobre a obesidade infantil abordando conceitos, epidemiologia e recomendações no manejo do problema.

Testes diagnósticos no contexto da avaliação de tecnologias em saúde: abordagens, métodos e interpretação / Diagnostic tests in the context of the health technologies assessment: approaches, methods, and interpretation

As Avaliações de Tecnologias em Saúde (ATS) no mundo todo, predominantemente tem sido focadas em medicamentos, dispositivos médicos terapêuticos e procedimentos, sobretudo, os cirúrgicos. Apesar de sua inquestionável importância na história natural de um grande número de doenças e do impacto econômico associado ao seu uso, os testes e exames diagnósticos (TED), considerando-se suas qualidade se consequentemente a acurácia dos mesmos, tem sido pouco avaliados no contexto da ATS. Há nítida escassez de estudos que avaliam os TED tanto do ponto de vista clínico e de segurança para o paciente, quanto do econômico. O propósito desse artigo é apresentar e discutir os conceitos inerentes ao uso dos TED, as abordagens para seu emprego, as metodologias de avaliação de suas propriedades e acurácia,bem como a interpretação de resultados dos TED, sejam eles realizados individualmente, ou sob a forma de síntese de estudos de acurácia. Espera-se que esse texto possa contribuir para melhor compreensão das especificidades encontradas nos estudos dos TED e estimular sua inclusão nas ATS...

The Health Technology Assessments (HTA) worldwide has been predominantly focused on drugs, medical devices and therapeutic procedures, above all, the surgeries. Despite its unquestionable importance in the natural history of a large number of diseases and of the economic impact associated with its use, the diagnostic exam and tests (DET), considering their qualities and hence the accuracy there of, has been not evaluated in the context of the HTA. There is a clear shortage of studies that evaluate the DET, both clinician and patient safety, and economical. The purpose of this article is to present and discuss the concepts inherent in the use of DET, the approaches to your employ, the methodologies of evaluation of their properties and accuracy, as well as the interpretation of results DET studies, whether performed individually or in the form of synthesis of studies of accuracy. It is hoped that this text may contribute to better understanding of the specifics found in studies of DET and encourage their inclusion in the HTA. I...

A family history of serious complications due to BCG vaccination is a tool for the early diagnosis of severe primary immunodeficiency.

Severe Combined Immunodeficiency (SCID) is one of the most severe forms of primary immunodeficiency (PID). Complications of BCG vaccination, especially disseminated infection and its most severe forms, are known to occur in immunodeficient patients, particularly in SCID. A carefully taken family history before BCG injection as well as delaying vaccination if PID is suspected could be a simple and effective method to avoid inappropriate vaccination of an immunodeficient child in some cases until the prospect of newborn screening for SCID has been fully developed. We describe a patient with a very early diagnosis of SCID, which was suspected on the basis of the previous death of two siblings younger than one year due to severe complications secondary to the BCG vaccine. We suggest that a family history of severe or fatal reactions to BCG should be included as a warning sign for an early diagnosis of SCID.

Factors associated with community-acquired pneumonia in hospitalised children and adolescents aged 6 months to 13 years old.

UNLABELLED: According to the World Health Organisation, community-acquired pneumonia is the main cause of paediatric death, accounting for 20 % of deaths in children younger than 5 years old, and 90 % of these deaths occur in non-industrialised countries. This study has as objective to evaluate the influence of socio-economic, environmental and breastfeeding factors on the occurrence of pneumonia. An unmatched case-control study was conducted in children aged 6 months to 13 years old at a children's hospital in Brazil. Multivariate analysis by logistic regression was performed to determine the variables used to predict pneumonia. A total of 252 children were selected. In the adjusted (by age) multivariate analysis, the following variables were associated with community-acquired pneumonia: (a) protective factors: breastfeeding >3 months, absence of other unrelated comorbidities, non-smoking mother, being the only child, child's age >5 years and mother's age >19 years old; (b) risk factors: maternal education <8 years and child's birth order [≥second]. In the multivariate analysis, considering only children from 6 months to 5 years old, the following variables were associated with community-acquired pneumonia: (a) protective factors: breastfeeding >3 months, non-smoking mother and no smokers in the child's bedroom; (b) risk factors: maternal education <8 years and prenatal complications. CONCLUSION: These findings contribute favourably to effectively minimising the risk factors related to the disease process and natural history of community-acquired pneumonia.

Patient with toxoplasmosis and glucose-6-phosphate dehydrogenase deficiency: a case report.

INTRODUCTION: Toxoplasmosis, a zoonotic protozoal disease caused by toxoplasma gondii, is prevalent throughout the world, affecting a large proportion of persons who usually have no symptoms. Glucose 6 phosphate dehydrogenase deficiency, an X-linked inherited disorder, is present in over 400 million people world wide. It is more common in tropical and subtropical countries and is one of the important causes of hemolytic anemia. CASE PRESENTATION: This case report relates the occurrence of the two diseases simultaneously in a child of five years old. CONCLUSION: Patients with glucose-6-phosphate dehydrogenase deficiency are more susceptible to toxoplasmosis and this case report, reinforce the findings of this propensity and alert us for such possibility, what it is important, therefore, the treatment of toxoplasmosis can cause serious hemolysis in these patients.

Do total, 78,3 por cento eram solteiros, 69,6 por cento estudavam, sendo que 45,5 por cento possuíam o 1º grau incompleto e 82,6 por cento não trabalhavam. A maioria (91,3 por cento) possuía hemofilia A. Quanto à avaliação da QV, 47,8 por cento responderam ser boa e 55 por cento possuíam um bom nível de satisfação com a saúde. O domínio psicológico apresentou o maior escore médio e o menor foi o do domínio meio ambiente. Com esse estudo conseguiu-se salientar a magnitude de alguns problemas dos hemofílicos.

The objective of this work was to characterize the quality of life of hemophilic patients being followed up in a specialized service. A cross-sectional study of hemophilic patients in a Regional Blood Bank of Brazil was carried out to evaluate their quality of life. The data were obtained by interviews employing the WHO QOL-brief questionnaire, which was analyzed using SPSS and Epi-info 6.04d computer programs. Twenty-three male patients with a mean age of 21 years old were interviewed. All reported that they live with their families, 47.8 percent were residents in Uberaba, 78.3 percent were single, 69.6 percent were students with 45.5 percent having a low level of education and 82.6 percent did not work. Of the 23 cases, 91.3 percent had hemophilia A. In respect to quality of life, 47.8 percent responded that their quality of life was good and 55 percent had a good level of satisfaction with their health. The psychological dominion presented the highest average score and the environment presented the lowest. This study highlights the magnitude of some problems of hemophilic patients.

Antigen detection for the diagnosis of pneumonia.

Streptococcus pneumoniae and Haemophilus influenzae type b are the main agents of bacterial community-acquired pneumonia in developing countries, although a definite etiologic diagnosis cannot be established in most cases. This study was carried out to assess the performance of a latex particle agglutination test (LPAT) from a commercial kit (Slidex Méningite Kit trade mark, BioMérieux, France) in diagnosing pneumococcal and H. influenzae type b pneumonia. One hundred and seven children (45 ill subjects and 62 healthy controls) were enrolled. All 45 cases had a presumptive diagnosis of bacterial pneumonia based on clinical (WHO criteria), laboratory (white blood cell count > or = 15.000/mm3, polymorphonuclear leukocytes > or = 70%, bands > or = 500/mm3, and C-reactive protein > or = 40 mg/l), and radiological findings, i.e., two or more positive points in the scoring system described by Khamapirad and Glezen (Semin Respir Infect 1987;2:130-144). Clinical, laboratory, and radiological assessments were performed in a blinded manner. LPAT was performed in urine samples after concentration through an ethanol-acetone solution. Sensitivity, specificity, and positive and negative predictive values were 77.3% (95% CI, 61.8-88.0%), 90.3% (95% CI, 79.5-96.0%), 85.0% (95% CI, 69.5-93.8%), and 84.8% (95% CI, 73.4-92.1%), respectively. Results suggest that LPAT is a useful diagnostic tool for the etiologic diagnosis of S. pneumoniae and H. influenzae type b pneumonia, especially in the developing world.
