Knowledge and practices regarding child development among primary healthcare professionals

OBJECTIVE: To evaluate the knowledge and practices regarding child development among physicians working in primary healthcare units. METHOD: Cross-sectional descriptive study carried out at primary healthcare units in Embu, São Paulo, Brazil. Study procedures: 1) Evaluation of knowledge: test consisting of 20 multiple-choice questions on child development applied to all 31 physicians who were providing pediatric care at the primary healthcare units; 2) Evaluation of practices: semi-structured interview applied to a sample of 154 mothers/caregivers of children aged up to 36 months during follow-up visits at primary healthcare units in the municipality. For the comparisons of categorical variables (evaluation/advices about development in visits of children at different ages), the chi-square test was employed. RESULTS: The mean number of correct responses among physicians was 14.8. The error rate for seven questions was greater than 30% (sensory development, language acquisition, physiology of the nervous system, clinical and laboratory diagnosis of congenital infections and innate errors of metabolism) and the rate of correct responses was greater than 85% for four questions (motor and personal-social development markers, risk factors and genetic syndromes). Regarding practices, in 69 (45%) visits, the doctor asked the mother/caregiver's opinion about the child's development; in 80 (52%), the mother/caregiver said that the doctor assessed the development; and in 64 (42%), the mother/caregiver said that the doctor advised them on practices for child's stimulation. CONCLUSIONS: Faulty knowledge and practices regarding child development were identified among primary care professionals, indicating the need for continued education.OBJETIVO: Avaliar o conhecimento e as práticas sobre desenvolvimento infantil de médicos que atuam em Unidades Básicas de Saúde (UBS). MÉTODO: Estudo transversal, descritivo, realizado nas UBS de Embu (SP). Procedimentos do estudo: 1) avaliação do conhecimento por teste contendo 20 questões de múltipla escolha sobre desenvolvimento da criança aplicado a 31 médicos (universo) que prestam assistência pediátrica em UBS; 2) avaliação das práticas - entrevista semiestruturada aplicada para uma amostra de 154 mães/cuidadores que acompanhavam crianças com idade menor ou igual a 36 meses em consulta médica agendada em UBS do município. Para comparação de variáveis categóricas (avaliação/orientações sobre desenvolvimento em consultas de crianças de diferentes faixas etárias), utizou-se o qui-quadrado. RESULTADOS: A média de acertos dos médicos foi de 14,8 questões; sete questões apresentaram índices de erros superiores a 30% (desenvolvimento sensorial, aquisição de linguagem, fisiologia do sistema nervoso, diagnóstico clínico e laboratorial de infecções congênitas, erros inatos do metabolismo) e quatro questões apresentaram acertos acima de 85% (marcos do desenvolvimento motor, pessoal-social, fatores de risco e síndrome genética). Quanto às práticas, em 69 (45%) consultas o médico perguntou a opinião da mãe/cuidador sobre o desenvolvimento da criança, em 80 (52%) a mãe/cuidador referiu que o médico fez alguma pergunta e/ou avaliou o desenvolvimento e em 64 (42%) orientou sobre como estimular a criança. CONCLUSÕES: Identificaram-se falhas de conhecimento e nas práticas dos profissionais referentes ao desenvolvimento da criança, o que indica a necessidade de implementar educação permanente.UNIFESP Curso de MedicinaUNIFESP Projeto DesenvolverSecretaria Municipal de Saúde do EmbuUNIFESP Departamento de Pediatria Disciplina de Pediatria Geral e ComunitáriaUNIFESP, Curso de MedicinaUNIFESP, Projeto DesenvolverUNIFESP, Depto. de Pediatria Disciplina de Pediatria Geral e ComunitáriaSciEL

Salvage radiotherapy for biochemical relapse after complete PSA response following radical prostatectomy: outcome and prognostic factors for patients who have never received hormonal therapy

OBJECTIVES: To evaluate the results of salvage conformal radiation therapy (3DC-EBRT) for patients submitted to radical prostatectomy (RP) who have achieved complete PSA response and who have never been treated with hormonal therapy (HT). To present the results of biochemical control, a period free from hormonal therapy and factors related to its prognosis. MATERIALS AND METHODS: from August 2002 to December 2004, 43 prostate cancer patients submitted to RP presented biochemical failure after achieving a PSA < 0.2 ng/ml. They have never received HT and were submitted to salvage 3DC-EBRT. Median age was 62 years, median preoperative PSA was 8.8 ng/ml, median Gleason Score was 7. Any PSA rise above 0.2 was defined as biochemical failure after surgery. Median 3DC-EBRT dose was 70 Gy, biochemical failure after EBRT was defined as 3 consecutive rises in PSA or a single rise enough to trigger HT. RESULTS: 3-year biochemical non-evidence of disease (BNED) was 71%. PSA doubling time lower than 4 months (p = 0.01) and time from recurrence to salvage EBRT (p = 0.04) were associated with worse chance of biochemical control. Biochemical control of 76% was achieved when RT had been introduced with a PSA lower than 1 ng/ml vs. 48% with a PSA higher than 1 (p = 0.19). Late toxicity was acceptable. CONCLUSION: 70% of biochemical control in 3 years can be achieved with salvage radiotherapy in selected patients. The importance of PSADT was confirmed in this study and radiotherapy should be started as early as possible. Longer follow up is necessary, but it is possible to conclude that a long interval free from hormonal therapy was achieved with low rate of toxicity avoiding or at least delaying several important adverse effects related to hormonal treatment

All-cause hospitalisation among people living with HIV according to gender, mode of HIV acquisition, ethnicity, and geographical origin in Europe and North America: findings from the ART-CC cohort collaboration

BACKGROUND: Understanding demographic disparities in hospitalisation is crucial for the identification of vulnerable populations, interventions, and resource planning. METHODS: Data were from the Antiretroviral Therapy Cohort Collaboration (ART-CC) on people living with HIV in Europe and North America, followed up between January, 2007 and December, 2020. We investigated differences in all-cause hospitalisation according to gender and mode of HIV acquisition, ethnicity, and combined geographical origin and ethnicity, in people living with HIV on modern combination antiretroviral therapy (cART). Analyses were performed separately for European and North American cohorts. Hospitalisation rates were assessed using negative binomial multilevel regression, adjusted for age, time since cART intitiaion, and calendar year. FINDINGS: Among 23 594 people living with HIV in Europe and 9612 in North America, hospitalisation rates per 100 person-years were 16·2 (95% CI 16·0-16·4) and 13·1 (12·8-13·5). Compared with gay, bisexual, and other men who have sex with men, rates were higher for heterosexual men and women, and much higher for men and women who acquired HIV through injection drug use (adjusted incidence rate ratios ranged from 1·2 to 2·5 in Europe and from 1·2 to 3·3 in North America). In both regions, individuals with geographical origin other than the region of study generally had lower hospitalisation rates compared with those with geographical origin of the study country. In North America, Indigenous people and Black or African American individuals had higher rates than White individuals (adjusted incidence rate ratios 1·9 and 1·2), whereas Asian and Hispanic people living with HIV had somewhat lower rates. In Europe there was a lower rate in Asian individuals compared with White individuals. INTERPRETATION: Substantial disparities exist in all-cause hospitalisation between demographic groups of people living with HIV in the current cART era in high-income settings, highlighting the need for targeted support.
