Factors associated with extubation failure in an intensive care unit: a case-control study / Fatores associados à falha de extubação em unidade de terapia intensiva: estudo de caso-controle / Factores asociados al fracaso de la extubación en unidad de cuidados intensivos: estudio de caso y control

Abstract Objective: to investigate the factors associated with extubation failure of patients in the intensive care unit. Method: unpaired, longitudinal, retrospective and quantitative case-control with the participation of 480 patients through clinical parameters for ventilator weaning. Data were analyzed by: Fisher's exact test or the chi-square test; unpaired two-tailed Student's t test; and Mann-Whitney test. Significant P values lower than or equal to 0.05 were admitted. Results: of the patients, 415 (86.5%) were successful and 65 (13.5%) failed. Success group: the most negative fluid balance, APACHE II in 20 (14-25), weak cough in 58 (13.9%). Failure group: the most positive fluid balance, APACHE II in 23 (19-29), weak cough in 31 (47.7%), abundant amount of pulmonary secretions in 47.7%. Conclusion: positive fluid balance and the presence of inefficient cough or inability to clear the airway were predictors of extubation failure.

Effectiveness and safety of tocilizumab for COVID-19: a systematic review and meta-analysis of randomized clinical trials

ABSTRACT BACKGROUND: Tocilizumab is an anti-human interleukin 6 receptor monoclonal antibody that has been used to treat coronavirus disease 2019 (COVID-19). However, there is no consensus on its efficacy for the treatment of COVID-19. OBJECTIVE: To evaluate the effectiveness and safety of tocilizumab for treating COVID-19. DESIGN AND SETTING: Systematic Review of randomized controlled trials (RCTs), Universidade Federal de São Paulo (UNIFESP), São Paulo (SP), Brazil. METHODS: We searched MEDLINE via PubMed, EMBASE, CENTRAL, and IBECS for RCTs published up to March 2021. Two authors selected studies and assessed the risk of bias and the certainty of the evidence following Cochrane Recommendations. RESULTS: Eight RCTs with 6,139 participants were included. We were not able to find differences between using tocilizumab compared to standard care on mortality in hospitalized patients with COVID-19 (risk ratio (RR) 0.97, 95% confidence interval (CI) 0.84 to 1.13; 8 trials; 5,950 participants; low-certainty evidence). However, hospitalized patients under tocilizumab plus standard care treatment seemed to present a significantly lower risk of needing mechanical ventilation (risk ratio = 0.78; 95% CI 0.64−0.94 moderate-certainty of evidence). CONCLUSIONS: To date, the best evidence available shows no difference between using tocilizumab plus standard care compared to standard care alone for reducing mortality in patients with COVID-19. However, as a finding with a practical implication, the use of tocilizumab in association to standard care probably reduces the risk of progressing to mechanical ventilation in those patients.

Cross-sectional evaluation of socioeconomic and clinical factors and the impact of fibromyalgia on the quality of life of patients during the COVID-19 pandemic

Abstract BACKGROUND: The fibromyalgia impact questionnaire (FIQ) relates to the functional capacity, professional situation, psychological disorders, and physical symptoms, and can identify the factors that determine the impact of the syndrome and characteristics of its carriers; the higher the score, the greater the impact of fibromyalgia on the quality of life. OBJECTIVE: To evaluate the impact of fibromyalgia on the quality of life of individuals with fibromyalgia, who were categorized according to the FIQ during the coronavirus disease pandemic. DESIGN AND SETTING: A cross-sectional study was conducted at an institution of higher education in Taquara, RS, Brazil. METHODS: A quantitative study was carried out, with the application of a sociodemographic and clinical questionnaire, and the FIQ in 163 Brazilian individuals with a medical diagnosis of fibromyalgia. Data were collected using SurveyMonkey software. RESULTS: Of the female carriers, 98.2% were living in urban areas, working, and under pharmacological and complementary treatment. The FIQ results showed that seven of the 10 items had the maximum score. The items "physical function" and "feel good" had intermediate scores, and the item "missed work" had a low score. The average total score was 79.9 points, indicating that fibromyalgia had a severe impact on the participants' lives. A severe impact of fibromyalgia was observed in 61.3% of the participants, a moderate impact in 30.7%, and a low impact in 8%. CONCLUSION: The survey findings suggest a severe impact in the majority of the Brazilian fibromyalgic population.

Tumores vasculares de interesse odontológico: aspectos clínicos e formas de tratamento / Vascular tumors of dental interest: clinical aspects and forms of treatment

Os hemangiomas são neoplasias benignas dos tecidos moles. São lesões caracterizadas pela proliferação de células endoteliais. Objetivos: O objetivo deste trabalho é demonstrar por meio de uma revisão da literatura os principais hemangiomas de interesse odontológico e suas características clínicas e abordagens terapêuticas. Revisão de literatura: O estudo mostrou prevalência de até 6% na população geral, sendo o tumor mais comum na infância. Essas lesões apresentam rápido crescimento pós-natal, que pode levar meses a dois anos em média, mas geralmente após esse período ocorre sua involução. O diagnóstico é comumente baseado nas características clínicas e na história do paciente. É importante entender que o estudo histopatológico pode ser necessário nos casos em que o diagnóstico é incerto, para diferenciá-lo de outras neoplasias graves. Destacam-se as principais complicações relacionadas a lesões, ulcerações e hemorragias, além de infecções secundárias que podem causar alto índice de morbidade. Assim, é fundamental que o dentista reconheça essas patologias e tenha capacidade para tratá-las. Considerações finais: Foi possível observar que os hemangiomas são manifestações vasculares incomuns para o cirurgião-dentista, porém o profissional deve saber diagnosticá-los e tratá-los. Dentre as áreas acometidas, essas lesões são frequentes na cavidade oral e o tratamento consiste em acompanhamento com intervenções conservadoras(AU)

Hemangiomas are benign soft tissue neoplasms. These are lesions characterized by the proliferation of endothelial cells. Objectives: The objective of this work is to demonstrate through a literature review about the main hemangiomas of dental interest and clinical characteristics and therapeutic approaches. Literature review: The study showed a prevalence of up to 6% in the general population, being the most common tumor in childhood. These lesions presents a rapid postnatal growth, which may take months until two years on average, but usually after this period their involution occurs. The diagnosis is commonly based on clinical characteristics and patient's history. It is important to understand that the histopathological study may be necessary in cases that the diagnostic is uncertainty, in order to differentiate it from other serious neoplasms. Main complications related to injuries, ulceration and hemorrhage can be highlighted, in addition to secondary infections that can cause a high rate of morbidity. Thus, it is essential that dentists recognize such pathologies and be able to treat them. Final considerations: Was possible do observe that hemangiomas are uncommon vascular manifestations for the dental surgeon, however, the professional must know to diagnose and treat them. Among the affected areas, these lesions are frequently seen in the oral cavity and the treatment consists of following up with conservative interventions(AU)

Parestesia do nervo alveolar inferior decorrente de procedimentos cirúrgicos e suas formas de tratamentos / Paresthesi of the lower alveolar nerve resulting from surgical procedures and its forms of treatment

Nas cirurgias odontológicas é possível que ocorra alguns acidentes ou complicações que podem interferir no dia a dia do paciente. A lesão do nervo alveolar inferior é uma complicação decorrente de cirurgias orais que podem causar um distúrbio de sensibilidade transitória ou persistente, na região do lábio inferior e na região delimitada do forame mentoniano e hemi-arco da mucosa. O diagnóstico da parestesia pode ser feito através de testes mecanoceptivos e nocioceptivos em que o profissional escolherá para qual melhor se adapte no paciente. O objetivo do presente trabalho foi abordar por meio de uma revisão de literatura as formas de diagnóstico e tratamento da parestesia do nervo alveolar inferior decorrentes de cirurgias orais. As bases de dados utilizadas para confecção desta revisão são encontradas nas bibliotecas virtuais eletrônicas: BVS (Biblioteca Virtual em Saúde), LILACS (Literatura Latino-Americana e do Caribe em Ciências da Saúde) e Pubmed. Como critério de inclusão foram selecionados artigos publicados de 2012 a 2022 em língua inglesa, portuguesa e espanhola. Após a leitura do título e resumo dos resultados da pesquisa e aplicação dos critérios de inclusão e exclusão dentre eles foram excluídos 883, pois não se enquadravam no nosso critério de inclusão. No final, foram selecionados 13 estudos por meio de base de dados, que serviram de base para esta revisão. Concluímos que as formas de tratamento para a parestesia na literatura, são um pouco escassas e conflitantes, mas relata que o uso da laserterapia e acupuntura tem sido uma forma de tratamento com um bom índice de sucesso, e para os casos que não sejam suficientes tais tratamentos, pode-se optar por uma cirurgia(AU)

In dental surgeries it is possible to have some accidents or complications that can interfere with the patient's day. Injury to the inferior alveolar nerve is a complication resulting from oral surgeries that can cause a disturbance of sensitivity that can be transient or persistent in the region of the lower lip and in the delimited region of the mental foramen and hemiarch of the mucosa. The diagnosis of paresthesia can be made through mechanoceptive and nocioceptive tests that the professional will choose, which best suits the patient. The objective of the present work is to approach, through a literature review, the forms of diagnosis and treatment aimed at inferior alveolar nerve paresthesia resulting from oral surgeries. The databases used for this review are found in the virtual electronic libraries: VHL (Virtual Health Library), LILACS (Latin American and Caribbean Literature on Health Sciences) and Pubmed. As inclusion criteria, articles published from 2012 to 2022 in English, Portuguese and Spanish were selected. After reading the title and summary of the research results and applying the inclusion and exclusion criteria, 883 were excluded, as they did not meet our inclusion criteria. In the end, 13 studies were selected from the database, which served as the basis for this review. We conclude that the forms of treatment for paresthesia in the literature are a little scarce and conflicting, but it reports that the use of laser therapy and acupuncture has been a form of treatment with a good success rate, and for cases that are not enough, such treatments, one can opt for surgery(AU)

Conservative management of newborns with 35 weeks or more of gestational age at risk for early-onset sepsis: a Brazilian cohort study

Abstract Objective: To evaluate the conservative management of newborns born at ≥35 weeks of gestational age, at risk for early-onset neonatal sepsis (EOS). Methods: Retrospective, analytic cohort study (2016 to 2019), including newborns ≥35 weeks of gestational at risk of EOS, asymptomatic at birth, managed conservatively in full rooming-in: serial physical examination and clinical observation for at least 48 h. They were classified into three groups, according to the clinical course: asymptomatic (group A), symptomatic for other reasons (group B), and with sepsis (group C). Risk factors, clinical signs and differential diagnoses of sepsis, length of stay, and discharge conditions were evaluated. Results: The authors evaluated 769 asymptomatic newborns at risk of EOS. (mean birth weight 2999 ± 485 g and gestational age 37.6 ± 1.7 weeks, respectively) corresponding to 12.2% of rooming-in admissions. The most prevalent risk factors were colonization by Group B Streptococcus (29%), prolonged rupture membrane duration (21.9%) and preterm labor (21.4%). Most of all of them (53.9%) remained asymptomatic (group A). Group B corresponded for 45.3%, and the most common clinical signs were hypothermia (24.5%), tremors (8.7%) and vomiting (8%). Environmental dysthermia (50.7%), prematurity (20.0%), and feeding intolerance (15.7%) were common in Group B. Laboratory tests were performed in 3.5%. Five patients (one confirmed) comprised group C (0.8/1,000 live births). There were no deaths. The median length of stay was 64 h (IQR 50-93). Conclusion: The rate of clinical/confirmed EOS was low. Most of the symptomatic patients only needed clinical evaluation to rule out sepsis. Management was shown to be safe.

Apoplejía pituitaria e infección por SARS-COV-2 (COVID-19) / Pituitary apoplexy and SARS-CoV-2 (COVID-19) infection

Resumen La infección por coronavirus (SARS-CoV-2/COVID-19) es responsable de un diverso rango de manifestaciones extrapulmonares entre las cuales se destaca el compromiso neurológico directo o indirecto. La apoplejía hipofisaria es una entidad médica y neuroquirúrgica de gravedad variable que suele asociarse a la presencia de un adenoma subyacente. Un escaso número de reportes han vinculado estas dos enfermedades entre sí. Este trabajo describe un caso de apoplejía hipofisaria manifestada clínicamente en for ma concomitante al diagnóstico de COVID 19, en un paciente con macroadenoma hipofisario desconocido y su manejo terapéutico, revisando los mecanismos potencialmente subyacentes al nexo entre ambas entidades.

Abstract Coronavirus disease (SARS-CoV-2/COVID-19) is responsible for a wide variety of extrapulmonary manifestations, among which direct or indirect neurological compromise stands out. Pituitary apoplexy is a clinical and neurosurgical entity of variable severity, usually associated with a pituitary adenoma. Literature is scarce regarding the association between these diseases. This paper reports a case of pituitary apoplexy, manifested concomitantly to the diagnosis of COVID 19 in a patient with unknown pituitary macroadenoma, and its therapeutic management, reviewing the mechanisms potentially underlying the link between both entities.

Quality of life and cognition in patients with Parkinson's disease during the covid-19 pandemic / Qualidade de vida e cognição em pacientes com a doença de Parkinson durante a pandemia da covid-19

Introduction: Restrictive isolation contributes to the containment of the virus, but it also has negative consequences for mental health. This study aimed to assess the quality of life, during the pandemic, in patients with Parkinson's disease (PD), compare it with measures before the pandemic, and identify factors that may be associated with non-compliance with cognitive intervention activities. Methods: The PDQ-39 questionnaire was reapplied in a sample of PD patients previously followed up in rehabilitation program. In addition, a questionnaire to assess the follow-up of cognitive training activities was elaborated. Results: Twenty-two individuals with mean age of 62.72(7.49) years and a mean duration of the disease of 8.7(3.30) years participated in this study. There was a statistically significant difference in the total score of the PDQ-39(p=0.048), as well as in the mobility (p=0.038), stigma (p=0.035), social support(p=0.045), and cognition(p=0.026) dimensions. When analyzing the questionnaire, it was observed that most of the sample was able to follow the guidelines received during the cognitive training group (77.3%), mainly reading activities (41%), games (35%), and applications (35%). However, 77.3% reported worsening cognition, with attention (50%) and memory (34%) being highlighted, as well as sadness, discouragement, and indisposition (72%), anxiety (77.27%), and difficulty falling asleep (68%). A total of 86.36% perceived the need for professional support in mental health. Conclusion: This study showed the impact of the pandemic on individuals with PD, leading to a worse perception of quality of life and subjective complaints related to sleep disturbance, cognitive impairment, and neuropsychiatric symptoms (depression and anxiety).

Introdução: O isolamento restritivo contribui para a contenção do vírus, mas também traz consequências negativas para a saúde mental. Este estudo teve como objetivo avaliar a qualidade de vida, durante a pandemia, em pacientes com doença de Parkinson (DP), compará-la com medidas anteriores à pandemia e identificar fatores que possam estar associados à não adesão às atividades de intervenção cognitiva. Métodos: O questionário PDQ-39 foi reaplicado em uma amostra de pacientes com DP previamente acompanhados em programa de reabilitação. Além disso, foi elaborado um questionário para avaliar o acompanhamento das atividades de treino cognitivo. Resultados: Participaram deste estudo 22 indivíduos com idade média de 62,72(7,49) anos e duração média da doença de 8,7(3,30) anos. Houve diferença estatisticamente significativa na pontuação total do PDQ-39(p=0,048), bem como na mobilidade (p=0,038), estigma (p=0,035), suporte social (p=0,045) e cognição (p=0,026) dimensões. Ao analisar o questionário, observou-se que a maior parte da amostra conseguiu seguir as orientações recebidas durante o grupo de treinamento cognitivo (77,3%), principalmente atividades de leitura (41%), jogos (35%) e aplicativos (35%). No entanto, 77,3% relataram piora da cognição, com destaque para atenção (50%) e memória (34%), além de tristeza, desânimo e mal-estar (72%), ansiedade (77,27%) e dificuldade para dormir (68%). Um total de 86,36% percebeu a necessidade de apoio profissional em saúde mental. Conclusão: Este estudo mostrou o impacto da pandemia em indivíduos com DP, levando a uma pior percepção da qualidade de vida e queixas subjetivas relacionadas a distúrbios do sono, comprometimento cognitivo e sintomas neuropsiquiátricos (depressão e ansiedade).

Vocal Folds Leukoplakia: The Efficacy of Vitamin A in the Initial Treatment

Abstract Introduction Laryngeal leukoplakia corresponds to a white lesion in the mucosa developed by the deposit of keratin in the epithelium, potentiated by chronic smoking. It is considered a preneoplastic lesion. Surgery is the most adopted treatment; however, non-surgical treatment is advocated by some authors. Objective To evaluate the effectiveness of vitamin A in the management of vocal fold leukoplakia. Methods Patients with videolaryngoscopy diagnosis of vocal fold leukoplakia were selected. The endoscopic images were photographed and with the aid of the ImageJ software (National Institutes of Health, Bethesda, MD, USA), the proportion of the size of the leukoplakia was calculated. Eligible patients were prescribed 50,000U of vitamin A, twice daily for 2 months, at which point videolaryngostroboscopy was repeated for comparative analysis between pre and posttreatment. The efficacy of the treatment was classified as: outcome I - complete improvement of the lesion, outcome II - partial improvement, and outcome III - no difference or increased lesion size. Results Fifteen patients (eight women, seven men) were included, six of whom had bilateral lesions. Smoking was reported in 86.8% of patients. Complete improvement of the lesion was found in 7 cases (33.4%, outcome I), partial improvement in 6 (28.6%, outcome II), and worsening of the injury in 8 (38.1%, outcome III). Of the latter, 6 underwent microsurgery; histopathology indicated absence of dysplasia in 3, and mild dysplasia in 3. Conclusions In this study, the treatment with vitamin A at a dose of 100,000 IU daily for 2 months was effective in reducing the laryngeal leukoplakia size in 62% of cases.

Upper Airway Stimulation in Patients with Obstructive Sleep Apnea: Long-Term Surgical Success, Respiratory Outcomes, and Patient Experience

Abstract Introduction Upper airway stimulation (UAS) with electric activation of the hypo-glossal nerve has emerged as a promising treatment for patients with moderate-to-severe obstructive sleep apnea. Objective To retrospectively analyze objective and subjective outcome measures after long-term follow-up in obstructive sleep apnea patients receiving upper airway stimulation. Methods An observational retrospective single-center cohort study including a consecutive series of patients diagnosed with obstructive sleep apnea receiving upper airway stimulation. Results Twenty-five patients were included. The total median apnea-hypopnea index (AHI) significantly decreased from 37.4 to 8.7 events per hour at the 12-month follow-up (p < 0.001). The surgical success rate was 96%. Adverse events were reported by 28% of the patients. Conclusion Upper airway stimulation is an effective and safe treatment for obstructive sleep apnea in patients with continuous positive airway pressure (CPAP) failure or intolerance. However, it is possible that the existing in and exclusion criteria for UAS therapy in the Netherlands have positively influenced our results.

Reinke Edema: Factors that Interfere with Vocal Recovery after Surgery

Abstract Introduction Dysphonia and lower pitch after surgery of Reinke edema are common. They are caused especially due to chronic smoking but, probably, other factors should be associated. Objectives To evaluate the results of laryngeal microsurgery in patients with Reinke edema, following a standardized postoperative guidance protocol in our service. Methods Retrospective study. Thirty patients (3 males; 27 females) were included, 70% between 41 and 60 years old. The parameters analyzed in the pre- and postoperative (between 4 and 6 months) of patients undergoing laryngeal microsurgery for Reinke edema were: smoking, vocal symptoms, videolaryngostroboscopy, voice therapy, perceptual and acoustic vocal evaluation, histopathological report. Results Smoking was reported by 100% of the patients and maintained in the postoperative period by 80%. Complete improvement of symptoms in the postoperative period was reported by 43% of them, partial improvement by 40%, and maintenance by 17%. There was low adherence to voice therapy in the pre- and postsurgery. Postoperative videolaryngoscopy indicated congestion (19), atrophy and bowed vocal fold (1), subepithelial edema (2), and normal findings (8). The histological findings were subepithelial edema, enlargement of vessels, inflammation, epithelial hyperplasia, and thickening of the basement membrane. The perceptual and acoustic vocal analyzes indicated improvement of the analyzed parameters. Conclusions The maintenance of some vocal symptoms and laryngeal alterations in videolaryngoscopy after microsurgery of Reinke edema is frequent, even in patients who follow the recommendations of vocal rest and control of gastroesophageal reflux. Vocal symptoms are attributed to changes in the laryngeal mucosa caused by chronic smoking, aggravated by the maintenance of addiction in the postoperative period.

Tratamiento agudo de la migraña durante el embarazo / Acute treatment of migraine during pregnancy

RESUMEN INTRODUCCIÓN La migraña es una condición médica prevalente y altamente discapacitante. Por lo general, durante el embarazo hay una reducción de los síntomas migrañosos, sin embargo, en ocasiones la sintomatología puede no mostrar mejoría, y en algunos casos empeorar. Por tanto, es necesario que el médico del servicio de urgencias realice un correcto diagnóstico de esta enfermedad, que descarte otros tipos de cefaleas y brinde el mejor y el más seguro tratamiento analgésico de acuerdo con la edad gestacional y perfil clínico de cada paciente. En esta revisión se abordará la relación entre la migraña y el embarazo, el papel de los estrógenos en la génesis de la migraña, así como también los datos más actuales en cuanto al tratamiento del manejo agudo de esta patología durante la gestación. MATERIALES Y METODOS: Se realizó una revisión sistemática de la literatura mundial sobre la relación entre la migraña y el embarazo y el manejo agudo en esta población, obteniéndose un total de 83 referencia bibliográficas. RESULTADOS: Como manejo inicial, se recomienda el uso de Acetaminofén más metoclopramida en cualquier etapa de la gestación. El uso de AINE debe evitarse a partir de la semana 20 de gestación. El Sumatriptán puede ser utilizado como segunda línea en cualquier trimestre. A todas las pacientes se les debe brindar manejo no farmacológico. CONCLUSIONES: Actualmente se cuenta con varios medicamentos y procedimientos seguros para el manejo agudo de la migraña en gestantes, sin embargo, debe tenerse en cuenta la edad gestacional ante su administración.

ABSTRACT INTRODUCTION: Migraine is a prevalent and highly disabling condition. Usually during pregnancy there is relief of symptoms, however, sometimes headache cannot improve, and some cases may get worse. Therefore, it is necessary for physicians who work at the emergency department perform a correct diagnosis of this pathology, rule-out other types of headaches and give the best and safest treatment according to gestational age and clinical profile of each patient. This review will address the relationship between migraine and pregnancy, the role of estrogens in the genesis of migraine. Updated information with respect to acute treatment of migraine during this period will be discussed. METHODS: A systematic review of the world literature on the relationship between migraine and pregnancy and acute management in this population was carried out, obtaining a total of 83 bibliographic references. RESULTS: As an initial management, the use of acetaminophen plus metoclopramide is recommended at any stage of pregnancy. The use of NSAIDs should be avoided from week 20 of gestation. Sumatriptan can be used as a second line in any trimester. Non-pharmacological management should be provided to all patients. CONCLUSIONS: There are currently safe drugs and procedures for the acute management of migraine in pregnant women, however, gestational age should be taken into account before administering them.

Non-reperfused ST-elevation myocardial infarction: notions from a low-to-middle-income country / Infarto de miocardio con elevación del ST no reperfundido: nociones de un país de ingresos bajos a medios

Abstract Objective: The objective of the study was to analyze the differences between survivors and non-survivors with non-reperfused ST-segment elevation myocardial infarction (STEMI) and to identify the predictors of in-hospital mortality. Methods: A retrospective cohort study included non-reperfused STEMI patients from October 2005 to August 2020. Patients were classified into survivors and non-survivors. We compared patient characteristics, treatments, and outcomes among the groups and identified factors associated with in-hospital mortality. Results: We included 2442 patients with non-reperfused STEMI and we found a mortality of 12.7% versus 7.2% in reperfused STEMI. The main reason for non-reperfusion was delayed presentation (96.1%). Non-survivors were older, more often women, and had diabetes, hypertension, or atrial fibrillation. The left main coronary disease was more frequent in non-survivors as well as three-vessel disease. Non-survivors developed more in-hospital heart failure, reinfarction, atrioventricular block, bleeding, stroke, and death. The main predictors for in-hospital mortality were renal dysfunction (HR 3.41), systolic blood pressure < 100 mmHg (HR 2.26), and left ventricle ejection fraction < 40% (HR 1.97). Conclusion: Mortality and adverse outcomes occur more frequently in non-reperfused STEMI. Non-survivors tend to be older, with more comorbidities, and have more adverse in-hospital outcomes.

Resumen Objetivo: Analizar las diferencias entre los sobrevivientes y no sobrevivientes con infarto agudo de miocardio no reperfundido y conocer los predictores de mortalidad intrahospitalaria. Métodos: Estudio de cohorte retrospectiva que incluyó pacientes con infarto agudo de miocardio no reperfundido de octubre de 2005 a agosto de 2020. Se clasificaron los pacientes de acuerdo a su estado de sobrevida y se compararon las características clínicas, tratamientos y desenlaces para poder identificar los predictores de mortalidad intrahospitalaria. Resultados: Se incluyeron 2442 pacientes con infarto agudo de miocardio no reperfundido, en los que se encontró una mortalidad de 12.7% vs 7.2% los que si recibieron tratamiento de reperfusión. La principal razón para no recibir tratamiento de reperfusión fue el retraso en la atención médica (96.1%). Los no sobrevivientes tuvieron mayor edad, fueron mujeres y tuvieron mayor frecuencia de diabetes, hipertensión y fibrilación atrial. El tronco de la coronaria izquierda y la enfermedad trivascular fueron más frecuentes en los que no sobrevivieron. Los pacientes que no sobrevivieron desarrollaron más insuficiencia cardiaca, reinfarto, bloqueo atrioventricular, sangrados, evento vascular cerebral y muerte. Los principales predictores de mortalidad intrahospitalaria fueron: insuficiencia renal (HR 3.41), tensión arterial sistólica al ingreso < 100 mmHg (HR 2.26) y fracción de eyección del ventrículo izquierdo < 40% (HR 1.97). Conclusiones: Los pacientes con infarto de miocardio no reperfundido tienen mayor mortalidad y desenlaces adversos. Los no sobrevivientes fueron mayores, con más comorbilidades y desarrollaron más desenlaces adversos intrahospitalarios.

Self-reported and objective sleep duration in patients with CKD: are they telling the same story? / Duração do sono autorrelatada e objetiva em pacientes com DRC: contam a mesma história?

Abstract Introduction: There is disagreement between data on sleep duration obtained from questionnaires and objective measurements. Whether this is also true for individuals with CKD is unknown. Here we compared self-reported sleep duration with sleep duration obtained by actigraphy. Methods: This prospective study included adult individuals with stage 3 CKD recruited between September/2016 and February/2019. We evaluated subjective sleep duration by asking the following question: "How many hours of actual sleep did you get at night?" Results: Patients (N=34) were relatively young (51 ± 13 years). Self-reported and measured sleep duration were 7.1 ± 1.7 and 6.9 ± 1.6 hours, respectively, with no correlation between them (p=0.165). Although the mean difference between measurements was 0.21 h, the limits of agreement ranged from -3.7 to 4.1 h. Conclusion: Patients with CKD who are not on dialysis have an erroneous sleep perception. Data on sleep duration should be preferentially obtained from objective measurements in patients with CKD.

Resumo Introdução: Há discordância entre os dados sobre duração do sono obtidos a partir de questionários e medições objetivas. Não se sabe se isto também é verdade para indivíduos com DRC. Aqui comparamos a duração do sono autorrelatada com a duração do sono obtida por meio de actigrafia. Métodos: Este estudo prospectivo incluiu indivíduos adultos com DRC estadio 3 recrutados entre Setembro/2016 e Fevereiro/2019. Avaliamos a duração subjetiva do sono, fazendo a seguinte questão: "Quantas horas de sono real você teve à noite?" Resultados: Os pacientes (N=34) eram relativamente jovens (51 ± 13 anos). A duração do sono autorrelatada e mensurada foi de 7,1 ± 1,7 e 6,9 ± 1,6 horas, respectivamente, sem correlação entre elas (p=0,165). Embora a diferença média entre as medições tenha sido de 0,21 h, os limites de concordância variaram de -3,7 a 4,1 h. Conclusão: Pacientes com DRC que não estão em diálise apresentam uma percepção equivocada do sono. Dados sobre a duração do sono devem ser obtidos preferencialmente a partir de medições objetivas em pacientes com DRC.

Adaptação Transcultural e Evidências de Validade do Questionário de Credibilidade/Expectativa / Cross-cultural adaptation and evidence of validity of the Credibility/Expectatncy Questionnaire / Adaptación transcultural y evidencias de validez del Cuestionario de Credibilidad/Expectativa

Resumo Este estudo teve como objetivos adaptar o Questionário de Credibilidade/Expectativa (QCE) (Credibility/Expectancy Questionnaire-CEQ) para o contexto brasileiro, avaliar suas propriedades psicométricas e apresentar as relações entre a credibilidade-expectativa do tratamento e variáveis sociodemográficas da amostra. Participaram 217 adultos, que declararam realizar acompanhamento psicológico, recrutados por meio de mídias sociais.

Factores asociados al consumo de sustancias psicoactivas de un grupo de pacientes con diagnóstico de esquizofrenia de una institución de salud mental de Medellín, Antioquia / Factors associated with the consumption of psychoactive substances in a group of patients diagnosed with schizophrenia from a mental health institution in Medellín, Antioquia / Fatores associados ao consumo de substâncias psicoativas em um grupo de pacientes com diagnóstico de esquizofrenia de uma instituição de saúde mental de Medellín, Colômbia

Objetivo: establecer la relación entre factores sociodemográficos y clínicos con el con­sumo de sustancias psicoactivas (SPA) en un grupo de pacientes con diagnóstico de esquizofrenia, atendidos en una institución de salud mental de la ciudad de Medellín, Colombia. Metodología: estudio observacional, retrospectivo de intención analítica, de un grupo de 268 pacientes atendidos en una institución de salud mental de Medellín, en los últi­mos seis meses del año 2021. Se identificaron factores sociodemográficos, de consumo de SPA y clínicos como tipo de medicamentos, reingresos hospitalarios y adherencia al tratamiento farmacológico. Se consideraron valores de Odds Ratio con intervalo de confianza (IC95%) y se identificaron factores asociados al consumo por medio de un modelo de regresión logística. Resultados: se identificó que el 34.7% de la muestra reporta consumo de SPA; variables clínicas asociadas, tipo de medicamentos, número de ingresos hospitalarios y adherencia al tratamiento. Se encontraron diferencias significativas en la edad entre el grupo de consumidores y no consumidores, con una mediana de edad menor para el grupo de consumidores. Se determinó que ser hombre, tener una mediana de edad de 27 años y estar desempleado representa un riesgo mayor para el consumo de SPA. Finalmente se establece que la edad, el sexo, la ocupación y la adherencia al tratamiento, podrían predecir el consumo en un 34%. Conclusiones: los pacientes jóvenes, en su mayoría hombres, con diagnóstico de es­quizofrenia, tienen mayor riesgo de consumo de SPA, lo que implica mayor riesgo de recaídas y menor adherencia al tratamiento farmacológico.

Objective: to establish the relationship between sociodemographic and clinical factors with the consumption of psychoactive substances (PAS) in a group of patients diagnosed with schizophrenia, treated at a mental health institution in the city of Medellín, Colombia. Methodology: observational, retrospective study with analytical intent, of a group of 268 patients treated at a mental health institution in Medellín, in the last six months of 2021. Sociodemographic, SPA consumption, and clinical factors such as the type of medication, hospital readmissions and adherence to drug treatment were identified. Odds Ratio values with confidence interval (95% CI) were considered and factors associated with consumption were identified by means of a logistic regression model. Results: it was shown that 34.7% of the sample reports PAS consumption, associated clinical variables, type of medication, number of hospital admissions, and adherence to treatment. Significant differences in age were found between the group of users and non-users, with a lower median age for the group of users. It was determined that being a man, having a median age of 27 years and being unemployed represent a greater risk for the consumption of PAS. Finally, it is established that age, sex, occupation, and adherence to treatment could predict consumption by 34%. Conclusions: young patients, mostly men, with a diagnosis of schizophrenia, have a higher risk of PAS consumption, which implies a higher risk of relapse and lower adherence to drug treatment.

Hidatidosis pancreática en una niña de 5 años / Pancreatic echinococcosis in a 5-year-old girl

La hidatidosis pancreática representa el 0,2-0,6 % de los casos, siendo la población pediátrica la de mayor riesgo. Las lesiones suelen localizarse en cabeza del páncreas (50-58 %); la localización en cuerpo y cola del páncreas se encuentra en el 24-34 % y el 19 %, respectivamente. Dada la posibilidad de complicaciones, suele realizarse tratamiento quirúrgico. Se sugiriere indicar albendazol antes y después del acto quirúrgico por los riesgos de ruptura y diseminación de los protoescólices. Se presenta el caso de una niña de 5 años de edad con dolor abdominal progresivo y lesión quística en páncreas compatible con hidatidosis en la ultrasonografía. En la tomografía computada se observa compresión de la vía biliar. La hemoaglutinación indirecta fue negativa. Presentó elevación de la bilirrubina total, con franco predominio de bilirrubina directa, y aumento de enzimas hepáticas. Se realizó laparotomía exploradora, colecistectomía y destechamiento del quiste. Evolucionó favorablemente, continuó con albendazol durante 3 meses luego de la cirugía.

Pancreatic echinococcosis accounts for 0.2­0.6% of cases, with the pediatric population being at a higher risk. Most commonly, pancreatic lesions occur in the head of the pancreas (50­58%); and in the body and tail in 24­34% and 19% of cases, respectively. Given the potential complications, surgery is usually performed. Albendazole is recommended before and after the surgery due to the risks for rupture and dissemination of protoscolices. Here we describe the case of a 5-year-old girl with progressive abdominal pain and cystic lesion in the pancreas compatible with echinococcosis in the ultrasound. The computed tomography showed bile duct compression. Indirect hemagglutination was negative. She had elevated total bilirubin, with a clear predominance of direct bilirubin, and high liver enzymes. Exploratory laparotomy, cholecystectomy, and unroofing of the cyst were performed. The patient had a favorable course and continued with albendazole for 3 months after the surgery.

Influence of temperature on the torsional properties of two thermally treated NiTi rotary instruments

Abstract This study aimed to evaluate the influence of temperature on torsional strength and angular deflection of two experimental NiTi rotary instruments manufactured from Blue and Gold thermal treatments and with identical cross-sections. A total of 40 experimental NiTi instruments 25.06 and with a triangular cross-section and manufactured from Blue and Gold thermal treatments were used (n=20). The torsional test was performed in the 3 mm from the tip of the instrument according to ISO 3630-1. The torsional test evaluated the torsional strength and angular deflection to failure at room temperature (21°C ± 1° C) and body temperature (36°C ±1°C). The fractured surface of each fragment was observed by using scanning electron microscopy (SEM). Data were analyzed using an unpaired t test for inter and intra-group comparison and the level of significance was set at 5%. The results showed that the body temperature did not affect the torsional strength and angular deflection of the instruments when compared with room temperature (P>0.05). However, at body temperature, the Blue NiTi instruments presented significantly lower angular deflection in comparison with Gold NiTi instruments (P<0.05). There was no significant difference regarding the torsional strength of the instruments at body temperature (P>0.05). The temperature did not affect the torsional strength of the instruments manufactured from Blue and Gold technology. However, the Blue NiTi instruments presented significantly lower angular deflection than Gold instruments at 36°C temperature.

Resumo O objetivo deste estudo foi avaliar a influência da temperatura nas propriedades de torção (resistência à torção e deflexão angular) de dois instrumentos rotatórios experimentais de NiTi fabricados com secção triangu.ar e tratamentos térmicos Blue e Gold. Quarenta instrumentos experimentais de NiTi 25.06 com tratamento térmico Blue e Gold foram usados (n= 20). Foi avaliada a resistência torcional e a deflexão angular até a fratura na temperatura ambiente (21°C ± 1°C) e corporal (36°C ± 1°C). O teste torcional foi realizado nos 3 mm da ponta dos instrumentos de acordo com a ISO 3630-1. A superfície fraturada de cada instrumento foi observada pelo microscópio eletrônico de varredura (MEV). Os dados foram analisados por meio do teste t não pareado para a comparação inter e intragrupos e o nível de significância à 5%. Os resultados demonstraram que a temperatura corporal não afetou a resistência a torção e deflexão angular quando comparada com a temperatura ambiente (P>0.05). No entanto, na temperatura de 36°C o instrumento com tratamento térmico Blue apresentou menor deflexão angular quando comparado com o Gold (P<0.05). Não houve diferença significante entre os dois instrumentos em relação a resistência à torção. A temperatura corporal não modificou a resistência torcional dos instrumentos fabricados com tecnologia Blue e Gold. No entanto, os instrumentos com NiTi Blue apresentaram menor deflexão angular do que o Gold a 36°C.
