Impact of the period of the day on all-cause mortality and major cardiovascular complications after arterial vascular surgeries.

BACKGROUND: Conflicting results are reported about daytime variation on mortality and cardiac outcomes after non-cardiac surgeries. In this cohort study, we evaluate whether the period of the day in which surgeries are performed may influence all-cause mortality and cardiovascular outcomes in patients undergoing non-cardiac arterial vascular procedures. METHODS: 1,267 patients who underwent non-cardiac arterial vascular surgeries between 2012 and 2018 were prospectively included in our cohort and categorized into two groups: morning (7 a.m. to 12 a.m., 79%) and afternoon/night (12:01 p.m. to 6:59 a.m. in the next day, 21%) surgeries. Primary endpoint was all-cause mortality within 30 days and one year. Secondary endpoints were the incidence of perioperative myocardial injury/infarction (PMI), and the incidence of major adverse cardiac events (MACE, including acute myocardial infarction, acute heart failure, arrhythmias, cardiovascular death) at hospital discharge. RESULTS: After adjusting for confounders in the multivariable Cox proportional regression, all-cause mortality rates at 30 days and one year were higher among those who underwent surgery in the afternoon/night (aHR 1.6 [95%CI 1.1-2.3], P = 0.015 and aHR 1.7 [95%CI 1.3-2.2], P < 0.001, respectively). Afternoon/night patients had higher incidence of PMI (aHR 1.4 [95%CI 1.1-1.7], P < 0.001). There was no significant difference in the incidence of MACE (aHR 1.3 [95%CI 0.9-1.7], P = 0.074). CONCLUSIONS: In patients undergoing arterial vascular surgery, being operated in the afternoon/night was independently associated with increased all-cause mortality rates and incidence of perioperative myocardial injury/infarction.

Probiotic therapy outcomes in body composition of children and adolescent with obesity, a nonrandomized controlled trial

ABSTRACT Objective: The objective of this study was to evaluate the impact of probiotic supplementation therapy on anthropometric values and body composition of children and adolescent with obesity. Subjects and methods: This is a nonrandomized controlled, prospective, double-blind interventional clinical trial with primary data analysis. The sample comprised 44 pubertal children and adolescent (8-17 years old) with obesity. The patients were allocated to probiotic (Lactobacillus rhamnosus) or placebo group, with matching of gender and chronological age. Both groups received nutritional guidance, and were followed for six months. In all patients the anthropometric assessment was carried out by a nutritionist and data on weight, height and waist circumference (WC) were collected. Body composition was assessed using dual emission X-ray absorptiometry (DXA). Results: After six months, both groups had increased weight, height but reduced body index mass (BMI) standard deviation score, with no differences between groups. After the intervention, both groups showed a reduction in the percentage of total body fat and an increase in lean mass, but only the placebo group showed a reduction in the percentage of trunk fat. However, the variation in these parameters did not differ between groups. Conclusions: The probiotic group does not seem to have benefited from supplementation. However, we suggest that this reduction in BMI SDS in both groups may have occurred due to improvements in diet because of the nutritional advice given throughout the therapy. We concluded that supplementation with this strain of probiotic was not effective in promoting weight loss or improving the body composition of this population.

The impact of COVID-19 in children and adolescents with obesity in Brazil.

Objective: The primary goal of the study was to evaluate weight gain in children and adolescents with obesity during the COVID-19 pandemic period, and compare it with the period before the pandemic. Methods: The sample comprised 68 children with obesity aged between 7 and 18 years, 30 (44.1%) boys and 38 (55.9%) girls, who were attended at the pediatric endocrinology clinic of the Irmandade da Santa Casa de Misericórdia de São Paulo, SP, Brazil. Weight gain in the sample in the pre-lockdown period (December 2, 2018 to March 11, 2020) was compared with that in the lockdown period (March 11, 2020 to February 21, 2021). Results: Approximately one year before the start of the pandemic period, the mean (SD) chronological age was 10.1 years old (± 2.4), and an average weight gain of 4.4 kg (± 4.8) was observed during the pre-lockdown period described. One year after the start of the pandemic, mean (SD) chronological age was 11.8 years old (± 2.4), and an average weight gain of 8.5 kg (± 7.6) was observed in the lockdown period described. When we compared the weight gain in the two periods, it was higher in the pandemic period, both in girls and boys (p = 0.013 and 0.035, respectively). Conclusion: The results of the study show that the period of social isolation adopted to mitigate the COVID-19 pandemic was associated with increased weight gain in the studied population, probably due to a reduction in physical activities and an increase in energy consumption.

Medical Students' Perception of Risk Factors for Cancer.

To evaluate the perception of risk factors for cancer among medical students and how it varies among students in different years of their medical education. Cross-sectional study was conducted in 2019. The American Institute for Cancer Research Cancer Risk Awareness Survey questionnaire was administered to medical students at the Centro Universitário Saúde ABC. Students were divided into those in their 1st to 3rd year and those in their 4th to 6th year of medical education. Qualitative variables were described by frequency and percentage, and quantitative variables were described by mean and standard deviation or median and interquartile range. The scores of the groups on the questionnaire were compared using Student's t test. The 95% confidence interval was calculated, and p values < 0.05 were considered significant. We included 196 students, with approximately 30 to 35 students in each year of medical education. The median age was 22 (18 to 31), with 74% being female. Among risk factors for cancer, smoking (100%), cancer-causing genes (99.48%), and excessive sunlight exposure (99.48%) were the most cited by students. We observed a significant difference in the number of correct answers, favoring students in their 4th to the 6th year over those in their 1st to the 3rd year (mean = 16.46 vs. mean = 13.73, p < 0.001). Perception about risk factors for cancer is greater in the later years of medical education.

Appendectomy: prognostic factors in the brazilian unified health system.

INTRODUCTION: Acute appendicitis (AA) is the most common cause of surgical acute abdomen. Postoperative complications in emergency care are reflections of the surgical procedure and pre- and postoperative factors. OBJECTIVE: Define prognostic factors for patients who underwent appendectomy, comparing them with the literature. METHODS: Descriptive observational study with a cross-sectional design based on data from the emergency/urgency appendectomy records between September 2018 and April 2019. Variables of interest were considered based on intrinsic patient data, clinical status, and perioperative management factors. Primary outcomes considered: postoperative complications from hospital admission discharge and prolonged hospital stay for > 2 days. Secondary outcome: death. The results were evaluated by Fisher's exact test (p <0.05). RESULTS: We identified 48 patients undergoing an appendectomy. Young adults accounted for 68.7%. From the total, 58.3% were males, 6 (12.5%) had hospitalization> 2 days, 4 (8.3%) had complications and no deaths. Among the variables, the stage of AA, the time of complaint up until seeking care, and advanced age were correlated with worse prognosis during hospitalization (p <0.05). The emergence of immediate postoperative complications was correlated with longer hospital stay (p <0.05). DISCUSSION: The descriptive data of the sample converge with the epidemiological profile of patients with AA in the literature, corroborating the applicability of conventional guidelines. The results strengthen the hypothesis that the patient's flow with abdominal manifestations is complicated from the first contact with SUS to the resolution of the condition. CONCLUSION: Knowledge of the epidemiological profile and perioperative predictors that are most related to complications favor the appropriate management of patients.

RESUMO INTRODUÇÃO: Apendicite aguda (AA) é causa mais comum de abdome agudo cirúrgico. Complicações pós-operatórias na emergência são reflexos do ato cirúrgico e fatores pré e pós-operatórios. OBJETIVO: Definir fatores prognósticos para paciente pós apendicectomia, comparando com a literatura. MÉTODOS: Estudo observacional descritivo e analítico com formação de base transversal de dados dos prontuários de apendicectomias de emergência/urgência entre setembro de 2018 e abril de 2019. Variáveis de interesse foram consideradas a partir dos dados intrínsecos ao paciente, quadro clínico e manejo perioperatório. Desfechos primários combinados considerados foram complicações pós-operatórias da internação até alta hospitalar e prolongamento da internação > dois dias. Desfecho secundário foi óbito. Resultados avaliados pelo teste exato de Fisher (p<0,05). RESULTADOS: Identificaram-se 48 pacientes submetidos à apendicectomia. Adultos jovens corresponderam a 68,7%. Do total, sexo masculino (58,3%), seis (12,5%) tiveram internação > dois dias, quatro (8,3%) cursaram com complicação e nenhum óbito. Dentre as variáveis consideradas, fase de apresentação da AA tempo de queixa até procura do atendimento e idade avançada correlacionaram com pior prognóstico durante internação (p<0,05). Surgimento de complicações pós-operatórias imediatas correlacionou-se com maior tempo de internação (p<0,05). DISCUSSÃO: Dados descritivos da amostra convergem com perfil epidemiológico de pacientes com AA na literatura, corroborando aplicabilidade das diretrizes convencionais. Resultados fortalecem a hipótese de que o fluxo do paciente com manifestações abdominais é complicado desde o primo-contato com o SUS até a resolução do quadro. CONCLUSÃO: Conhecimento do perfil epidemiológico e dos preditores perioperatórios que mais se relacionam com complicações favorecem manejo adequado dos pacientes.

Depression, anxiety and spirituality in oncology patients.

OBJECTIVE To relate anxiety and depression levels to the spirituality levels of oncology patients in the ABC region. METHODS Cross-sectional study performed at the ABC University Center oncology outpatient clinics. For the evaluation of spirituality, the Religiosity, Spirituality, and Personal Beliefs instrument of the World Health Organization (SRPB-WHO) was applied. To evaluate the levels of depression and anxiety, the Hospital Anxiety and Depression Scale (HADS) was applied. Qualitative variables were described by frequency and percentage, and quantitative variables by mean and standard deviation or median and range. Relationships were established using either the T-test or Wilcoxon-Mann-Whitney test and correlations with Pearson or Spearman tests, depending on the normality assessed by the Shapiro-Wilk test. RESULTS We included 99 patients, 68% female, with a median age of 60 years (19 to 81). A total of 24% had high or borderline levels of anxiety and 21% of depression. There was a negative correlation between levels of depression and spirituality (rho = -0.44, p <0.001), and anxiety and spirituality (rho=-0.232, p=0.02). We found no significant difference between levels of anxiety, depression, or spirituality when stratified by schooling, income, ethnicity, or marital status. There was a positive correlation between levels of anxiety and depression (cor = 0.477, p <0.001). CONCLUSION Spirituality can be a complementary tool in the treatment of patients with cancer.

Perception of risk factors for cancer in the ABC population.

OBJECTIVE To evaluate the knowledge about risk factors for cancer in patients treated at the ABC Medical School (FMABC). METHODS Cross-sectional observational study conducted in 2019. The American Cancer Institute's Cancer Risk Awareness Survey questionnaire was used with 29 cancer risk factors, 14 of which were proven to cause cancer and 15 without consensus or scientific evidence of causality with cancer but that are often reminded by most of the population. Qualitative variables were described by frequency and percentage, and quantitative variables by mean and standard deviation or median and range depending on normality, assessed by the Shapiro-Wilk test. The study was conducted in accordance with the Helsinki Declaration for Research and approved by the Research Ethics Committee. RESULTS 191 patients were included. Median age 54 (20 to 90), 64% female. 35.6% reported current or previous smoking. 3.1% consumed alcohol more than 5 drinks/week. 56% reported sedentary lifestyle. 44% had at least 1 case of cancer in relatives up to 2nd degree. The average of correct answers in the analyzed population was 12.83 ± 3.06. A weak positive correlation was observed between income and number of cases (rho = 0.177, p = 0.02). No relationship was observed between the number of correct answers and level of education, age, sex, marital status, race or patients with a positive family history for cancer. CONCLUSION The knowledge about risk factors for cancer in the ABC population is low, which may contribute to the adoption of risk behaviors for the disease.

Bone age determination in eutrophic, overweight and obese Brazilian children and adolescents: a comparison between computerized BoneXpert and Greulich-Pyle methods.

BACKGROUND: Bone age determination is usually employed to evaluate growth disorders and their treatment. The Greulich-Pyle method is the simplest and most frequently used type of evaluation, but it presents huge interobserver variability. The BoneXpert is a computer-automated method developed to avoid significant bone age variability among distinct observers. OBJECTIVE: To compare the BoneXpert and Greulich-Pyle methods of bone age determination in eutrophic children and adolescents, as well as in overweight and obese pediatric patients. MATERIALS AND METHODS: The sample comprised 515 participants, 253 boys (159 eutrophic, 53 overweight and 41 obese) and 262 girls (146 eutrophic, 76 overweight and 40 obese). Left hand and wrist radiographs were acquired for bone age determination using both methods. RESULTS: There was a positive correlation between chronological age and Greulich-Pyle, chronological age and BoneXpert, and Greulich-Pyle and BoneXpert. There was a significant increase (P<0.05) in bone age in both the Greulich-Pyle and BoneXpert methods in obese boys when compared to eutrophic or overweight boys of the same age. In girls, there was an increase in bone age in both obese and overweight individuals when compared to eutrophic girls (P<0.05). The Greulich-Pyle bone age was advanced in comparison to that of BoneXpert in all groups, except in obese boys, in which bone age was similarly advanced in both methods. CONCLUSION: The BoneXpert computer-automated bone age determination method showed a significant positive correlation with chronological age and Greulich-Pyle. Furthermore, the impact of being overweight or obese on bone age could be identified by both methods.

Parry-Romberg syndrome: severity of the deformity does not correlate with quality of life.

BACKGROUND: The aims of this study were to (1) describe the main clinical findings of Parry-Romberg syndrome (PRS), (2) evaluate surgical strategies and outcomes, and (3) investigate the quality of life of patients according to their disease severity. METHODS: This retrospective observational study involved 14 patients treated between 2005 and 2011. The surgical treatment strategies were based on the proposed system for grading severity, and postoperative outcomes were assessed. The patients answered two questionnaires that covered the clinical manifestations of the syndrome and their quality of life in the postoperative period. A comparative analysis between the severity of the deformity and the quality of life was performed using the Kruskal-Wallis and Mann-Whitney tests. RESULTS: The most prevalent clinical manifestation of PRS was progressive hemifacial atrophy (85.71 %). The surgical strategy was individualized based on the severity of disease of each patient. Surgical strategies included free-fat grafts, dermal fat grafts, and bone grafts associated with a temporoparietal fascia flap. Regardless of approach, all patients had an overall improvement in their facial appearance and were free of complications during the follow-up period. Our data showed no association between the severity of the deformity and the quality of life of these patients (all p > 0.05). CONCLUSIONS: In this series, there was a predominance of clinical features of PRS that had been previously reported. Satisfactory outcomes were obtained using different surgical strategies that varied according to the severity of the deformity. The severity of the deformity did not impose a reduced quality of life on PRS patients. LEVEL OF EVIDENCE IV: This journal requires that authors assign a level of evidence to each article.

Acesso subfrontal para ressecções crâniofaciais anteriores / To access subfrontal previous craniofacial resections

Introdução: Tumores malignos ou benignos primários ou comenvolvimento da base do crânio constituem problema de difícilmanuseio cirúrgico devido a proximidade de estruturas nobrese da potencialidade de complicações pósoperatórias graves,como meningites e fístulas liquóricas. A redução da morbidade,mortalidade e complexidade peri e pósoperatórias é o que busca amaioria dos cirurgiões que lidam nesta área. Os autores propõemacesso subfrontal para ressecções crânio faciais anteriores comredução significativa da morbidade, mortaldiade e complexidadecirúrgicas. Método: 55 pacientes submetidos à ressecção crâniofacial anterior por acesso sub frontal no Hospital e MaternidadeCelso Pierro (PUC Campinas) e do Hospital Heliópolis (São Paulo)através de uma única equipe cirúrgica. Acesso cirúrgico através derinotomia lateral nos pacientes sem acometimento de seio maxilare de incisão de Weber Fergusson para aqueles que apresentavaminvasão deste seio associado a remoção da parede anterior do seiofrontal e ossos nasais. Resultado: Complicações: 1 caso de infartoagudo do miocárdio, 2 casos de fístula liquórica, 1 caso de fístulaantral, 2 necroses de retalho e 1 caso de septicemia. Média desobrevida de 35,21 meses dos pacientes com neoplasias malignas,existindo 20 pacientes vivos sem doença. Discussão: O acessosubfrontal permite a realização de ressecções crânio faciais paratumores malignos e benignos com mínima retração cerebral, o queleva a diminuição da morbidade peri e pósoperatória, total controledas margens cirúrgicas e facilidade nas técnicas reconstrutivas,além de incisões estéticas e funcionalmente agradáveis. Apresentavantagens sobre técnicas atuais como a abordagem endoscópica,devido ao controle das margens ciúrgicas no que diz respeitoaos tumores malignos. Nesta casuística um baixo índice decomplicações é apresentado pelo acesso subfrontal, graças àvia de acesso ampla, que facilita o manuseio e reconstrução comreconstrução da duramáter de maneira hermética. Também permitea realização da cirurgia com uma única equipe cirúrgica pelo fato denão necessitar de manuseio do parênquima cerebral. Conclusão:Via de acesso permite manuseio amplo e, consequentemente,adequado para as ressecções crânio faciais anteriores. O acessotem menor índice de complicações pósoperatórias. A cirurgiapossível com uma única equipe cirúrgica.
