RESUMO
BACKGROUND: During the COVID-19 pandemic, there was a shortage of filtering facepiece respirators (FFR), leading to prolonged use and reuse of FFRs. METHODS: FFRs were collected in 3 hospitals after extended use (up to 15 or 30days). We assessed the physical characteristics and filtration levels of worn FFRs, before sterilization. Respirators that achieved at least 94% filtration of aerosol particles, nasal clip still attached, had no tears, had preserved elastic bands, and had no dirt were randomized to receive or not receive cleaning before being submitted to hydrogen peroxide plasma gas sterilization. RESULTS: A total of 1,055 FFRs were collected. Over 85% of them exhibited secured nose clips, preserved strap elasticity, and no tears. However, more than 78% of samples contained dirt, leaving only 101 (19.6%) eligible to undergo sterilization. After sterilization, none of the FFRs in either group achieved minimum filtration, although 72% without cleaning and 80% with cleaning had filtration between 90.0% and 93.9%. DISCUSSION: A large proportion of FFRs were ineligible for sterilization due to factors unrelated to health care (eg, dirt from makeup). CONCLUSIONS: Prolonged reuse of FFRs significantly reduced aerosol filtration efficiency. Eligible FFRs did not maintain 94% filtration after sterilization with or without cleaning.

OBJECTIVE: To determine if functional measures of ambulation can be accurately classified using clinical measures; demographics; personal, psychosocial, and environmental factors; and limb accelerations (LAs) obtained during sleep among individuals with chronic, motor incomplete spinal cord injury (SCI) in an effort to guide future, longitudinal predictions models. DESIGN: Cross-sectional, 1-5 days of data collection. SETTING: Community-based data collection. PARTICIPANTS: Adults with chronic (>1 year), motor incomplete SCI (N=27). INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Ambulatory ability based on the 10-m walk test (10MWT) or 6-minute walk test (6MWT) categorized as nonambulatory, household ambulator (0.01-0.44 m/s, 1-204 m), or community ambulator (>0.44 m/s, >204 m). A random forest model classified ambulatory ability using input features including clinical measures of strength, sensation, and spasticity; demographics; personal, psychosocial, and environmental factors including pain, environmental factors, health, social support, self-efficacy, resilience, and sleep quality; and LAs measured during sleep. Machine learning methods were used explicitly to avoid overfitting and minimize the possibility of biased results. RESULTS: The combination of LA, clinical, and demographic features resulted in the highest classification accuracies for both functional ambulation outcomes (10MWT=70.4%, 6MWT=81.5%). Adding LAs, personal, psychosocial, and environmental factors, or both increased the accuracy of classification compared with the clinical/demographic features alone. Clinical measures of strength and sensation (especially knee flexion strength), LA measures of movement smoothness, and presence of pain and comorbidities were among the most important features selected for the models. CONCLUSIONS: The addition of LA and personal, psychosocial, and environmental features increased functional ambulation classification accuracy in a population with incomplete SCI for whom improved prognosis for mobility outcomes is needed. These findings provide support for future longitudinal studies that use LA; personal, psychosocial, and environmental factors; and advanced analyses to improve clinical prediction rules for functional mobility outcomes.

We assessed safety and potential efficacy of a chamomile gel compared with urea cream to prevent acute radiation dermatitis in head and neck cancer patients. We assessed safety and potential efficacy of the chamomile gel in escalating concentrations of 2.50%, 5.00% and 8.35% of chamomile. Concentration of 8.35% was chosen for a randomized trial comparing chamomile gel (8.35%) with urea cream (n = 24 per group), for potential efficacy to delay or prevent radiation dermatitis in these patients. Preliminary results demonstrate a delayed onset of dermatitis, with onset of Grade 2 dermatitis at 5.1 (1.3) weeks in the chamomile group and 4.5 (1.3) weeks in the urea group (effect size of 0.46). Itching, burning and hyperpigmentation were more frequently reported in the urea group. Results indicates a potential efficacy of the chamomile gel. Further studies are needed to confirm the effect of the chamomile gel in reducing or delaying the occurrence of radiation dermatitis.

OBJECTIVE: this study investigated the association of somatic and cognitive-affective symptoms with sex and age, among patients hospitalized with heart disease. METHOD: this study was a secondary analysis of two previous observational studies totaling 531 patients with heart disease, hospitalized from 2005 to 2011 in two public hospitals in Ribeirão Preto, state of São Paulo, Brazil. Somatic and cognitive-affective symptoms were assessed using the subscales of the Beck Depression Inventory - I (BDI-I). RESULTS: of 531 participants, 62.7% were male, with a mean age 57.3 years (SD= 13.0) for males and 56.2 years (SD= 12.1) for females. Analyses of variance showed an effect of sex (p<0.001 for somatic and p=0.005 for cognitive-affective symptoms), but no effect of age. Women presented with higher mean values than men in both BDI-I subscales: 7.1 (4.5) vs. 5.4 (4.3) for somatic, and 8.3 (7.9) vs. 6.7 (7.2) for cognitive-affective symptoms. There were no differences by age for somatic (p=0.84) or cognitive-affective symptoms (p=0.84). CONCLUSION: women hospitalized with heart disease had more somatic and cognitive-affective symptoms than men. We found no association of somatic and cognitive-affective symptoms with age. Future research for these patients could reveal whether these differences according to sex continue throughout the rehabilitation process.

OBJETIVO: investigar a associação de sintomas somáticos e cognitivo-afetivos ao sexo e à idade de pacientes hospitalizados com doença cardíaca. MÉTODO: este estudo é resultado de uma análise secundária de dois estudos observacionais anteriores, totalizando 531 pacientes com doença cardíaca, internados de 2005 a 2011, em dois hospitais públicos em Ribeirão Preto, estado de São Paulo, Brasil. Os sintomas somáticos e cognitivo-afetivos foram avaliados utilizando-se as subescalas do Inventário de Depressão de Beck - I (IDB-I). RESULTADOS: dos 531 participantes, 62,7% são do sexo masculino, com média de idade de 57,3 anos (DP= 13,0) para os homens e 56,2 anos (DP = 12,1) para as mulheres. A análise da variância mostrou um efeito relacionado ao sexo do paciente (p<0,001 para sintomas somáticos e p=0,005 para os sintomas cognitivo-afetivos), mas nenhum efeito relacionado à idade. As mulheres apresentaram maiores escores do que os homens em ambas subescalas IDB-I: 7,1 (4,5) e 5,4 (4,3) para os sintomas somáticos, e 8,3 (7,9) e 6,7 (7,2) para os sintomas cognitivo-afetivos, respectivamente. Não houve diferenças referentes à idade para sintomas somáticos (p=0,84) ou sintomas cognitivo-afetivos (p=0,84). CONCLUSÃO: as mulheres internadas com doença cardíaca apresentaram mais sintomas somáticos e cognitivo-afetivos do que os homens. Não houve associação dos sintomas somáticos e cognitivo-afetivos com a idade. Pesquisas futuras desses pacientes poderiam revelar se essas diferenças de acordo com o sexo permanecem durante todo o processo de reabilitação. .

AIMS: To test an educational programme with telephone follow-up to improve self-care in Brazilian patients who underwent percutaneous coronary intervention. BACKGROUND: Percutaneous coronary intervention has been established as a treatment for coronary disease. However, additional intervention is needed to improve self-care for individuals who undergo this procedure to reduce further disease. Telephone follow-up is one strategy that has been used to improve chronic disease self-care. DESIGN: Randomized controlled trial. TRIAL REGISTRATION: ClinicalTrials.gov, NCT01341093. METHODS: Sixty patients who were preparing for their first percutaneous coronary intervention between 2011-2012 were randomly allocated to an educational programme with telephone follow-up (N = 30) or a control group (N = 30). Perceived health status was assessed with the Medical Outcomes Study 36-Item Short Form. Self-efficacy, symptoms of anxiety and depression and medication adherence were also assessed. Measures were collected before intervention (baseline) and 6 months later. RESULTS: Both groups improved from baseline to 6 months in the 'Physical Component Summary' and in the domains of 'Physical Functioning', 'Role-Emotional' and 'Role-Physical'. The educational programme group showed a reduction in anxiety from baseline to 6-month follow-up, while the control group showed a slight increase. No differences in symptoms in depression and self-efficacy were found and both groups reported high levels of medication adherence. CONCLUSION: The educational programme with telephone follow-up is a promising intervention as it led to reduction in anxiety for those receiving the educational programme. Further improvements in timing and focus of the educational programme, such as targeting emotional and social lifestyle changes, might be warranted.
