Prognostic value of perioperative high sensitivity troponin in patients undergoing hip and knee arthroplasty.

The authors conducted a prospective observational study to investigate the prognostic value of high-sensitivity Troponin I (hs-TnI) in the short- and long-term periods after orthopedic surgery, including Total Hip and Knee Arthroplasty (THA and TKA, respectively), in a tertiary orthopedic center in Brazil. Perioperative Myocardial Injury (PMI) was defined as an absolute increase in hs-TnI of ≥ 26 ng/L above preoperative values. The primary endpoint was all-cause mortality assessed at 30 days and 18 months after surgery. The secondary endpoint consisted of a composite outcome: cardiovascular death, acute myocardial infarction, angina requiring revascularization, and/or stroke. The authors compared Relative Risks (RR) of all-cause mortality and composite outcomes in patients with or without PMI at 30 days and 18 months. A Cox proportional hazards model for long-term outcomes was calculated and adjusted for age > 70 years, gender, and Revised Cardiac Risk Index (RCRI) class ≥ 2. PMI occurred in 3.4 % of all surgeries. At 30-days, 6.6 % of patients with PMI had died versus none without PMI. At 18 months, 20.0 % of PMI versus 4.7 % without PMI had died (RR = 5.0; 95 % Confidence Interval [95 % CI 1.3-19.3]). Based on composite outcomes in short and long-term periods, the RRs were 16.2 (95 % CI 2.7-96.5) and 7.7 (95 % CI 2.2-26.6), respectively. PMI was associated with all-cause mortality after 18 months and increased risk for a composite outcome (Hazard Ratio [HR = 3.97], 95 % CI 1.13-13.89 and HR = 5.80, 95 % CI 1.93-17.45, respectively). Patients with PMI who underwent THA or TKA presented worse short- and long-term prognoses compared to those without PMI.

Core Competencies Self-Assessment and Patient-Practitioner Orientation during the First Year of a Brazilian Orthopedic Residency.

Objective Training a competent physician requires to direct the resident profile of graduate students for practice activities. We sought to identify the doctor-patient relationship orientation and the self-assessment of the core competencies, which they pointed out needed to be developed. Methods All 56 orthopedic residents admitted between 2016 and 2019 participated in the present prospective observational study. The Patient Practitioner Orientation Scale (PPOS) and a self-assessment questionnaire were answered at the beginning and end of the first year of residency (R1) in Orthopedics and Traumatology. We calculated mean and standard deviation for PPOS items and scores and analyzed them through the paired t-test. Self-Assessment Questionnaire answer options were "yes" or "I need to improve it" and skills were classified in decreasing order of the frequency of "I need to improve it" responses with description of absolute number and percentage. We compared frequencies using Fisher Test. P-values < 0.05 were considered statistically significant. GraphPad Prism 8.4.3 (GraphPad Software, San Diego, CA, USA) and Microsoft Excel (Microsoft Corporation, Redmond, WA, USA) were used for statistical analysis. Results In the period between the beginning and the end of R1, the total PPOS mean score significantly decreased from 4.63 to 4.50 ( p = 0.024), more biomedical-focused. Around one-third of the residents identified competencies of patient care, practice-based learning and improvement, and interpersonal and communication skills as needed to improve. Conclusions The PPOS and self-assessment activities could promote reflection practices and are possible tools for learner-centered competency assessment. Biomedical guidance tends to prevail as the training of physicians progresses, and periodic self-assessments can be worked on to build a growth mindset.

Resumo Objetivo A formação de um médico competente requer direcionar o perfil de pós-graduação residente para atividades práticas. Buscou-se identificar a orientação de relacionamento médico-paciente e a autoavaliação das competências fundamentais que eles apontaram que precisavam ser desenvolvidas. Métodos Todos os 56 residentes em ortopedia admitidos entre 2016 e 2019 participaram do presente estudo observacional prospectivo. A Escala de Orientação Médico-Paciente (Patient Practitioner Orientation Scale [PPOS, na sigla em inglês]) e um questionário de autoavaliação foram respondidos no início e no final do primeiro ano de residência (R1) em Ortopedia e Traumatologia. Calculamos o desvio médio e padrão para itens e pontuações de PPOS e os analisamos através do teste t emparelhado. As opções de resposta do Questionário de Autoavaliação foram "sim" ou "preciso melhorar" e as habilidades foram classificadas na ordem decrescente da frequência das respostas "preciso melhorar" com descrição de número absoluto e percentual. Comparamos frequências usando o teste de Fisher. Consideramos significativos valores-p < 0,05. Os programas GraphPad Prism 8.4.3 (GraphPad Software, San Diego, CA, EUA) e Microsoft Excel (Microsoft Corporation, Redmond, WA, EUA) foram utilizados para análise estatística. Resultados No período entre o início e o final do R1, a média total de PPOS diminuiu significativamente, de 4,63 para 4,50 (p= 0,024), mais focada em biomédica. Cerca de um terço dos residentes identificou competências do cuidado ao paciente, aprendizagem e melhoria baseadas na prática e habilidades interpessoais e de comunicação, como necessitando melhorar. Conclusões As atividades de PPOS e autoavaliação podem promover práticas de reflexão e são possíveis ferramentas para avaliação de competência centrada no aluno. A orientação biomédica tende a prevalecer à medida que a formação dos médicos progride e as autoavaliações periódicas podem ser trabalhadas para construir uma mentalidade de crescimento.

Profile of neurological disorders in a tertiary center of education in orthopedics.

BACKGROUND: Neurological conditions can cause secondary orthopedic disorders and can result from orthopedic surgical procedures. In addition, misdiagnosis and overtreatment involve both specialties. Epidemiological studies of neurological patients in tertiary units are often performed in emergency departments of general hospitals or rehabilitation centers. OBJECTIVE: Describe the clinical and epidemiologic profile of neurological disorders in a Brazilian federal tertiary center and education hospital in orthopedics in Rio de Janeiro. METHODS: We performed a retrospective study of the medical records of patients attended by neurology specialists of the internal medicine's department of the National Institute of Traumatology and Orthopedics from February 2014 to March 2020. RESULTS: We reviewed neurological referrals in the medical records of 1,349 patients in the period. The mean age of patients was 49.67 years (standard deviation [SD] ± 18.99). There was a predominance of females, corresponding to 751 (55.7%) patients. Regarding ethnicity, 684 (50.7%) participants were white, 550 (40.8%) non-white, and 115 (8.5%) non-classified. Peripheral neuropathies (34.1%), osteoarticular diseases (10%), epilepsy (8.3%), developmental disorders (7.9%), and neuromuscular diseases (7.3%) were the 5 groups with the largest numbers of cases. CONCLUSION: The sample consisted mostly of females and white individuals, and approximately one third of the cases were of peripheral neuropathies. Epidemiological studies in neurology from tertiary centers of another medical specialty can improve the professional development of both specialties. This interdisciplinary approach can also optimize resources, help avoid misdiagnosis, and reduce disability.

ANTECEDENTES: Condições neurológicas tanto podem causar distúrbios ortopédicos secundários como podem ser consequências de procedimentos cirúrgicos ortopédicos. Além disso, erros de diagnóstico e sobre tratamento também envolvem ambas as especialidades. Estudos epidemiológicos de atendimento neurológico em unidades terciárias de saúde são geralmente realizados em serviços de emergência ou em centros de reabilitação. OBJETIVO: Descrever o perfil clínico e epidemiológico de diagnósticos em neurologia em um centro terciário de saúde no Brasil e hospital de educação em ortopedia no Rio de Janeiro. MéTODOS: Realizamos um estudo retrospectivo com revisão de prontuários dos pacientes atendidos pela neurologia do setor de clínica médica do Instituto Nacional de Traumatologia e Ortopedia no período de fevereiro de 2014 a março de 2020. RESULTADOS: Revisamos os prontuários de 1.349 pacientes atendidos pela neurologia no período. A média de idade dos pacientes foi de 49,67 anos (desvio padrão [DP] ± 18,99). Houve predomínio do sexo feminino correspondendo a 751 (55,7%) dos atendimentos. Quanto à etnia, a amostra foi composta de 684 (50,7%) de brancos, 550 (40,8%) de não brancos e 115 (8,5%) de não classificados. Neuropatias periféricas (34,1%), doenças osteoarticulares (10%), epilepsias (8,3%), transtornos do desenvolvimento (7,9%) e doenças neuromusculares (7,3%) corresponderam aos 5 grupos com os maiores números de casos. CONCLUSãO: A amostra se constituiu predominante de indivíduos do sexo feminino, brancos, e cerca de um terço dos casos corresponderam às neuropatias periféricas. Estudos de perfil de atendimento neurológico em hospitais terciários de outra especialidade médica podem aperfeiçoar a capacitação de ambos os profissionais. Esta abordagem interdisciplinar também pode otimizar recursos, contribuir para evitar erros diagnósticos e reduzir incapacidades.

The lifestyle of Brazilian medical students: What changed and how it protected their emotional wellbeing during the COVID-19 pandemic.

BACKGROUND AND OBJECTIVES: Adopting healthy lifestyle pillars promotes longer lives free from major chronic diseases. The COVID-19 pandemic imposed behavioural changes and psychological burdens. The aim of this study was to assess changes in medical students' six lifestyle pillars that were imposed by the COVID-19 pandemic. METHOD: This cross-sectional study included 548 Brazilian medical students' digitally collected demographic data and lifestyle characteristics from before and during the pandemic. RESULTS: The pandemic had a neutral impact on sleep quality and a predominantly negative impact on interpersonal relationships, exercise and eating. Approximately 67.5% students decreased their tobacco and alcohol use. Spirituality was maintained at 66%. Those who reported having emotional wellbeing (27.9%) during the pandemic fulfilled a higher number of pre-pandemic lifestyle pillars (median [IQR]) when compared with those who reported an absence of wellbeing (4 [3-4] pillars, compared with 3 [2-4], P = 0.006). DISCUSSION: The results reinforce the importance of adhering to as many lifestyle pillars as possible to preserve emotional wellbeing during periods of stress such as those experienced during the pandemic.

Efeitos do uso de antiinflamatório e do exercício aeróbico sobre a regeneração tecidual e perfil biomecânico do tendão calcâneo de ratos após ruptura completa / Effects of anti-inflammatory and aerobic exercise on tissue regeneration and biomechanical profile of Achilles tendon of rats after complete rupture

Ruptura do tendão calcâneo é uma das lesões tendíneas mais frequentes. Embora a maioria dos trabalhos sugira que o exercício seja benéfico na cicatrização tendínea, não há consenso sobre o efeito do antiinflamatório neste contexto. Trabalhos experimentais tentam reproduzir lesão aguda deste tendão, em diferentes espécies animais. Neste estudo, descrevemos uma técnica de tenotomia completa do tendão calcâneo direito em ratos e, em seguida, avaliamos os efeitos do uso do antiinflamatório e do exercício aeróbico, isoladamente e em combinação, sobre a proliferação celular e o perfil biomecânico do tendão calcâneo, durante o processo de cicatrização após tenotomia. Estudo experimental com 156 ratos machos adultos, da raça Wistar, com idade média de 3 meses e peso médio de 300g. Após anestesia com tiopental e com auxílio da miscroscopia de luz, foi realizada incisão longitudinal posterior de cinco milímetros, em direção proximal, a partir da tuberosidade posterior do calcâneo da pata direita do rato. Foi feito corte trasnversal do tendão calcâneo, a sete milímetros da tuberosidade do calcâneo, com preservação do tendão plantar. Utilizamos as técnicas de Hematoxilina e Eosina, Picrosirius-red e Resorcina-fucsina de Weigert para avaliação da cicatrização tendínea e das fibras dos sistemas colágeno e elástico. Após a tenotomia, metade dos animais receberam tenoxicam intramuscular por 7 dias e no oitavo dia iniciou-se protocolo de exercício em esteira na metade de cada grupo. Os ratos foram divididos aleatoriamente em 4 grupos de tratamento: A - sem antiinflamatório E sem exercício (controle); B - com antiinflamatório E com exercício; C - sem antiinflamatório E com exercício; D - com antiinflamatório E sem exercício. Os animais foram eutanasiados com 1, 2, 4 e 8 semanas após a tenotomia, para avaliação histológica pelo PCNA, e biomecânica através do teste de resistência à tração e da medida do ciclo locomotor. Foram realizados análise de variância...

Achilles tendon rupture is one of the most frequent tendon injuries. Although most studies have shown the benefits of exercise on tendon regeneration, controversy still exists concerning non-steroidal antinflammatory drug (NSAID) effects in this context. Several experimental models have been used for the study of Achilles tendon injury. In this study, we describe the surgical technique of right Achilles tenotomy in rats and subsequently, evaluate the effects of NSAID and aerobic exercise, in an isolated fashion and combined, on cell proliferation and biomechanical aspects of the Achilles tendon after tenotomy. Experimental study with 156 male Wistar rats with an average age of 3 months and with average weight of 300g. Surgical procedures were performed under light microscopy, after anesthesia with thiopental. A five millimeters posterior longitudinal incision was created, proximally directed, starting five millimeters proximal to the posterior calcaneal tuberosity. A complete tenotomy of the Achilles tendon was performed, seven millimeters away from the calcaneal tuberosity. The plantaris tendon was preserved. We used Hematoxilin and Eosin, Picrosirius-red and Weigert's Resorcin-fucsin to observe general tendon healing, especially regarding collagen and elastic fibers. After tenotomy, half of the rats received an intramuscular injection of tenoxican for 7 days and exercise was initiated on the 8th day for half the animals of each group. Rats were randomly divided into four treatment groups: A) no NSAID and no exercise; B) NSAID plus exercise; C) no NSAID, with exercise; D) NSAID and no exercise. Animals were sacrificed at 1, 2, 4 and 8 weeks after the tenotomy and cell proliferation was evaluated by immunohistochemistry for PCNA, biomechanical evaluation was performed with ultimate load and gait cycle analysis was also carried out. We used the test of analysis of variance, the Kruskal-Wallis test and also, Bonferroni method, in the R Project program 2.11.1...

[Effects of greater-than-5% weight reduction on hemodynamic, metabolic and neuroendocrine profiles of grade I obese subjects]. / Efeitos da redução de peso superior a 5% nos perfis hemodinâmico, metabólico e neuroendócrino de obesos grau I.

OBJECTIVE: To evaluate the effects of a greater-than-5% weight reduction in hemodynamic, metabolic, and neuroendocrine profiles of grade I obese subjects. METHODS: Observational study with 47 grade I obese subjects, with mean age of 33 years who received monthly orientation regarding diet, physical exercises, and eating behavior for four months. Blood pressure using the auscultatory method and pulse rate were assessed monthly, whereas the following variables (and respective methods) were measured at the beginning and at the end of the study: total cholesterol, triglycerides, HDL-cholesterol (enzymatic method), LDL-cholesterol (Friedewald formula), blood glucose (hexokinase method), leptin, adiponectin, renin, aldosterone, insulin (radioimmunoassay) and insulin-resistance index (HOMA). RESULTS: After adjustment for other variables, significant reductions of 6 mmHg in diastolic blood pressure, 7 pg/ml in renin, 13 mg/dl in total cholesterol and 12 mg/dl in LDL-cholesterol were observed in the greater-than-5% weight reduction group. Also, a tendency to a higher increase in adiponectin levels by the end of the study, as well as a three-fold higher reduction in blood glucose, insulin, and HOMA levels, and a six-fold higher reduction in leptin levels were observed in this group. CONCLUSION: Non-pharmacological measures that promote a greater-than-5% weight reduction produce hemodynamic, metabolic, and neuroendocrine effects that improve the cardiovascular risk of obese subjects.

Efeitos da redução de peso superior a 5 por cento nos perfis hemodinâmico, metabólico e neuroendócrino de obesos grau I / Effects of greater-than-5 percent weight reduction on hemodynamic, metabolic and neuroendocrine profiles of grade I obese subjects

OBJETIVO: Avaliar os efeitos da redução de peso superior a 5 por cento nos perfis hemodinâmico, metabólico e neuroendócrino de obesos grau I. MÉTODOS: Estudo observacional com 47 obesos grau I, média de idade de 33 anos, submetidos a orientação mensal quanto a dieta, exercício físico e comportamento alimentar, durante quatro meses. A pressão arterial, pelo método auscultatório, e a freqüência cardíaca, pelo método palpatório, foram avaliadas mensalmente, enquanto as seguintes variáveis (e respectivos métodos) foram medidas no início e final do estudo: colesterol total, triglicerídeos, HDL-colesterol (enzimático), LDL-colesterol (fórmula de Friedwald), glicemia (enzimático hexoquinase), leptina, adiponectina, renina, aldosterona, insulina (radioimunoensaio) e índice de resistência à insulina (HOMA). RESULTADOS: Observamos, após ajuste para outras variáveis, reduções significativas de 6 mmHg na pressão arterial diastólica, 7 pg/ml na renina, 13 mg/dl no colesterol total e 12 mg/dl no LDL-colesterol, no grupo com redução de peso superior a 5 por cento. Notamos, também nesse grupo, tendência ao aumento de maior magnitude da adiponectina ao final do estudo, bem como diminuição três vezes maior dos níveis de glicemia, insulina e HOMA, e seis vezes maior da leptina. CONCLUSÃO: Medidas não-farmacológicas capazes de promover redução de peso superior a 5 por cento produzem efeitos hemodinâmicos, metabólicos e neuroendócrinos que melhoram o risco cardiovascular de obesos.
