Abstract Objective: the purpose of this pre-feasibility study was to examine perceptions and experiences of a Sit-to-stand activity with urban Brazilian community-dwelling older people in their homes. Method: the exploration method was focused ethnography. Purposive sampling was used to recruit 20 older people. Five means of data generation were used, namely: socio-demographic surveys, participant observations, informal interviews, formal semi-structured interviews, and field notes. Data analysis was qualitative content analysis. Results: the experience of mobility-challenged older people with the Sit-to-stand activity was dependent on their mobility expectations involving many factors that worked together to influence their beliefs and attitudes towards the activity, preferences, behaviors, and cultural perceptions. The participants of this study seemed to find the activity enjoyable; however, the most noticeable shortcomings for their engagement in the Sit-to-stand activity emerged as gaps in their personal and intrapersonal needs. Conclusion: the recommendations generated from the study findings call for the design of implementation strategies for the Sit-to-stand intervention that are tailored to this particular population's needs.

Exploring the Feasibility of Machine Learning to Predict Risk Stratification Within 3 Months in Chest Pain Patients with Suspected NSTE-ACS / 生物医学与环境科学（英文）

OBJECTIVE@#We aimed to assess the feasibility and superiority of machine learning (ML) methods to predict the risk of Major Adverse Cardiovascular Events (MACEs) in chest pain patients with NSTE-ACS.@*METHODS@#Enrolled chest pain patients were from two centers, Beijing Anzhen Emergency Chest Pain Center Beijing Bo'ai Hospital, China Rehabilitation Research Center. Five classifiers were used to develop ML models. Accuracy, Precision, Recall, F-Measure and AUC were used to assess the model performance and prediction effect compared with HEART risk scoring system. Ultimately, ML model constructed by Naïve Bayes was employed to predict the occurrence of MACEs.@*RESULTS@#According to learning metrics, ML models constructed by different classifiers were superior over HEART (History, ECG, Age, Risk factors, & Troponin) scoring system when predicting acute myocardial infarction (AMI) and all-cause death. However, according to ROC curves and AUC, ML model constructed by different classifiers performed better than HEART scoring system only in prediction for AMI. Among the five ML algorithms, Linear support vector machine (SVC), Naïve Bayes and Logistic regression classifiers stood out with all Accuracy, Precision, Recall and F-Measure from 0.8 to 1.0 for predicting any event, AMI, revascularization and all-cause death ( vs. HEART ≤ 0.78), with AUC from 0.88 to 0.98 for predicting any event, AMI and revascularization ( vs. HEART ≤ 0.85). ML model developed by Naïve Bayes predicted that suspected acute coronary syndrome (ACS), abnormal electrocardiogram (ECG), elevated hs-cTn I, sex and smoking were risk factors of MACEs.@*CONCLUSION@#Compared with HEART risk scoring system, the superiority of ML method was demonstrated when employing Linear SVC classifier, Naïve Bayes and Logistic. ML method could be a promising method to predict MACEs in chest pain patients with NSTE-ACS.

Feasibility study of immediate breast reconstruction with fusion fascia combined with implants / 中华肿瘤杂志

Objective: To investigate the oncologic and surgical safety of the fused fascia method for immediate breast reconstruction with implants. Methods: The clinical data of 343 patients with immediate breast reconstruction with implants in Tianjin Medical University Cancer Hospital from 2014-2017 were retrospectively analyzed to compare the 5-year local recurrence-free survival, 5-year disease-free survival and 5-year overall survival of patients with breast reconstruction by fusion fascia and other methods, and to analyze the complication incidences of implant removal between different implant groups. Results: Of the 343 patients with breast reconstruction, 95 were in the fused fascia group (fascia group) and 248 were in the non-fascia group (25 in the bovine pericardial patch group and 223 in the muscle flap group). At a median follow-up of 49 months, the differences in 5-year local recurrence-free survival (90.1% and 94.9%, respectively), 5-year disease-free survival (89.2% and 87.6%, respectively), and 5-year overall survival (95.2% and 95.1%, respectively) between patients in the fascial and non-fascial groups were not statistically significant (P>0.05). The complication incidence of implant removal was 24.0% (6/25) in the patch group and 2.1% (2/95) and 2.2% (5/223) in the fascia and muscle flap groups, respectively. Conclusion: Immediate breast reconstruction with fused fascial combined with implant is safe and feasible, less invasive than muscle flaps, more economical and with fewer complications than patches.

Feasibility study of using bridging temporary permanent pacemaker in patients with high-degree atrioventricular block after TAVR / 中华心血管病杂志

Objective: To determine the feasibility of using temporary permanent pacemaker (TPPM) in patients with high-degree atrioventricular block (AVB) after transcatheter aortic valve replacement (TAVR) as bridging strategy to reduce avoidable permanent pacemaker implantation. Methods: This is a prospective observational study. Consecutive patients undergoing TAVR at Beijing Anzhen Hospital and the First Affiliated Hospital of Zhengzhou University from August 2021 to February 2022 were screened. Patients with high-degree AVB and TPPM were included. Patients were followed up for 4 weeks with pacemaker interrogation at every week. The endpoint was the success rate of TPPM removal and free from permanent pacemaker at 1 month after TPPM. The criteria of removing TPPM was no indication of permanent pacing and no pacing signal in 12 lead electrocardiogram (EGG) and 24 hours dynamic EGG, meanwhile the last pacemaker interrogation indicated that ventricular pacing rate was 0. Routinely follow-up ECG was extended to 6 months after removal of TPPM. Results: Ten patients met the inclusion criteria for TPPM, aged (77.0±11.1) years, wirh 7 females. There were 7 patients with third-degree AVB, 1 patient with second-degree AVB, 2 patients with first degree AVB with PR interval>240 ms and LBBB with QRS duration>150 ms. TPPM were applied on the 10 patients for (35±7) days. Among 8 patients with high-degree AVB, 3 recovered to sinus rhythm, and 3 recovered to sinus rhythm with bundle branch block. The other 2 patients with persistent third-degree AVB received permanent pacemaker implantation. For the 2 patients with first-degree AVB and LBBB, PR interval shortened to within 200 ms. TPPM was successfully removed in 8 patients (8/10) at 1 month without permanent pacemaker implantation, of which 2 patients recovered within 24 hours after TAVR and 6 patients recovered 24 hours later after TAVR. No aggravation of conduction block or permanent pacemaker indication were observed in 8 patients during follow-up at 6 months. No procedure-related adverse events occurred in all patients. Conclusion: TPPM is reliable and safe to provide certain buffer time to distinguish whether a permanent pacemaker is necessary in patients with high-degree conduction block after TAVR.

Safety and feasibility of right colectomy via a transvaginal approach: early experience from a single center / 中华胃肠外科杂志

Objective: To investigate the safety and feasibility of performing right colectomy via a transvaginal approach. Methods: This was a retrospeltive cohort study. Data of 30 patients who had undergone transvaginal laparoscopic right colectomy (transvaginal group) and 23 women who had undergone laparoscopic right colectomy (laparoscopic group) from January 2019 to March 2022 in the Division of Colorectal Surgery, Department of General Surgery, Peking Union Medical College Hospital were collected retrospectively. The inclusion criteria for the transvaginal group were as follows: (1) post-menopausal woman; (2) transverse diameter of the tumor < 6 cm; and (3) diagnosis of benign polyps that were unresectable by endoscopy, mucinous tumors of the appendix, or confirmed right colon cancer not requiring D3 lymphadenectomy. The inclusion criteria for the laparoscopic group were as follows: (1) pathologically confirmed adenocarcinoma or high-grade intraepithelial neoplasia; (2) lesion located from the cecum to the right third of the transverse colon; and (3) clinically stage T1-4NanyM0. The exclusion criteria for the laparoscopic group were as follows: (1) distant metastasis discovered during surgical exploration; (2) multiple organ resection required or R0 resection not possible; or (3) conversion to open surgery required. Safety was evaluated on the basis of intra- and post-operative complications. Feasibility was assessed by postoperative recovery and quality of operative specimen. The body mass index was lower in the transvaginal than the laparoscopic group (22.0±3.1 kg/m2 vs. 24.1±2.6 kg/m2, t=2.617, P=0.012). Results: Among the 30 transvaginal laparoscopic right colectomies, 26 were pure transvaginal surgeries, three required laparoscopic assistance because of difficulties with anastomosis (n=2) or abdominal adhesions (n=1), and one required conversion to laparoscopic surgery because of vascular injury. Compared with the laparoscopic group, the transvaginal group had a longer surgery time (175.0 [147.5, 216.3] minutes vs. 120.0 [100.0, 120.0] minutes, U=63.000, P<0.001) and more blood loss (30.0 [10.0, 50.0] ml vs. 23.0 [10.0, 20.0] ml, U=208.000, P=0.011). The incidence of intraoperative complications (16.7% [5/30) vs. 0, P=0.061] was comparable between the two groups. In the transvaginal group, the sites of intraoperative injuries were bladder (n=3), ileocecal artery (n=1), and right uterine artery (n=1). The incidence of postoperative complications (20.0% [6/30] vs. 17.4% [4/23], χ2<0.001,P>0.999) was also comparable between the two groups. Clavien-Dindo grade III postoperative complications occurred in two patients in the transvaginal group (one patient had a pelvic hematoma that required embolization; the other had a vesico-vaginal fistula that required surgery). Postoperative visual analogue scale scores were significantly lower (P<0.001) in the transvaginal group. Times to first flatus, ambulation, and first intake and duration of postoperative hospital stay were comparable between the two groups (P>0.05). The proportion of specimens of moderate quality was 83.3% (25/30) in the transvaginal group and 100% (23/23) in the laparoscopic group; this difference is not significant (P=0.061). Among patients who underwent D2 lymph node dissection, the number of lymph nodes examined was comparable between the transvaginal (n=23) and laparoscopic groups (n=7) (18 [15, 27] vs. 20 [16, 29], U=69.500, P=0.589). Conclusion: Transvaginal right colon surgery is associated with less postoperative pain than laparoscopic surgery, but is not yet the preferred alternative because of the incidence of surgical complications.

Feasibility of a single-port thoracoscopy-assisted five-step laparoscopic procedure via transabdominal diaphragmatic approach for No.111 lymphadenectomy in patients with Siewert type II esophageal gastric junction adenocarcinoma / 中华胃肠外科杂志

Objective: We aimed to explore the feasibility of a single-port thoracoscopy- assisted five-step laparoscopic procedure via transabdominal diaphragmatic(TD) approach(abbreviated as five-step maneuver) for No.111 lymphadenectomy in patients with Siewert type II esophageal gastric junction adenocarcinoma (AEG). Methods: This was a descriptive case series study. The inclusion criteria were as follows: (1) age 18-80 years; (2) diagnosis of Siewert type II AEG; (3) clinical tumor stage cT2-4aNanyM0; (4) meeting indications of the transthoracic single-port assisted laparoscopic five-step procedure incorporating lower mediastinal lymph node dissection via a TD approach; (5) Eastern Cooperative Oncology Group performance status (ECOG PS) 0-1; and (6) American Society of Anesthesiologists classification I, II, or III. The exclusion criteria included previous esophageal or gastric surgery, other cancers within the previous 5 years, pregnancy or lactation, and serious medical conditions. We retrospectively collected and analyzed the clinical data of 17 patients (age [mean ± SD], [63.6±11.9] years; and 12 men) who met the inclusion criteria in the Guangdong Provincial Hospital of Chinese Medicine from January 2022 to September 2022. No.111 lymphadenectomy was performed using five-step maneuver as follows: superior to the diaphragm, starting caudad to the pericardium, along the direction of the cardio-phrenic angle and ending at the upper part of the cardio-phrenic angle, right to the right pleura and left to the fibrous pericardium , completely exposing the cardio-phrenic angle. The primary outcome includes the numbers of harvested and of positive No.111 lymph nodes. Results: Seventeen patients (3 proximal gastrectomy and 14 total gastrectomy) had undergone the five-step maneuver including lower mediastinal lymphadenectomy without conversion to laparotomy or thoracotomy and all had achieved R0 resection with no perioperative deaths. The total operative time was (268.2±32.9) minutes, and the lower mediastinal lymph node dissection time was (34.0±6.0) minutes. The median estimated blood loss was 50 (20-350) ml. A median of 7 (2-17) mediastinal lymph nodes and 2(0-6) No. 111 lymph nodes were harvested. No. 111 lymph node metastasis was identified in 1 patient. The time to first flatus occurred 3 (2-4) days postoperatively and thoracic drainage was used for 7 (4-15) days. The median postoperative hospital stay was 9 (6-16) days. One patient had a chylous fistula that resolved with conservative treatment. No serious complications occurred in any patient. Conclusion: The single-port thoracoscopy-assisted five-step laparoscopic procedure via a TD approach can facilitate No. 111 lymphadenectomy with few complications.

OBJECTIVE@#To evaluate the clinical efficacy of spinal endoscopy in the treatment of severe free lumbar disc herniation and explore the feasibility and application of microscopic drills to expand ventral space.@*METHODS@#Thirty patients with severe free lumbar intervertebral disc herniation treated by spinal endoscopic technique from April 2019 to March 2021 were collected, including 19 males and 11 females;aged from 19 to 76 years with an average of (44.03±16.92) years old. All patients had a single segmental lesion with prolapse of the nucleus pulposus. Among them, there were 3 cases on L2,3, 3 cases on L3,4, 15 cases on L4,5, and 9 cases on L5S1. During operation, posterior bone of vertebral body and pedicle notch were removed by a drill under the endoscope to enlarge the ventral space. And the free nucleus pulposus was exposed and completely removed. The intraoperative blood loss, operation time, hospital stay and postoperative neurological complications were recorded, and Japanese Orthopaedic Association (JOA) score, Oswestry Disability Index (ODI) and visual analogue scale (VAS) were compared before operation, 2 days, 3 months and 1 year after operation, and Macnab standard was used to evaluate clinical efficacy.@*RESULTS@#All operations were successful and the free nucleus pulposus was completely removed. Pain in the lower back and legs was significantly relieved on the day after operation. Two patients experienced transient pain and numbness in lower limbs after operation, and no serious nerve injury complications occurred. ODI and VAS at each time point after surgery were significantly lower than those before surgery (P<0.01), and JOA score was significantly higher than before surgery (P<0.01). The excellent and good rates of Macnab were 66.67% (20/30), 83.33% (25/30) and 90.00% (27/30) on 2 days, 3 months and 1 year after operation, respectively.@*CONCLUSION@#For severe free lumbar intervertebral disc herniation, using of a drill under endoscope to expand the ventral space can smoothly remove the free nucleus pulposus and avoid nerve damage.

OBJECTIVE@#This study aimed to investigate the feasibility of implementing a manual therapy technique (muscle energy technique, MET) protocol in a hospital pulmonary rehabilitation (PR) program for patients with moderate to severe chronic obstructive pulmonary disease (COPD). Please cite this article as: Baxter DA, Coyle ME, Hill CJ, Worsnop C, Shergis JL. Muscle energy technique for chronic obstructive pulmonary disease: A feasibility study. J Integr Med. 2023; 21(3): 245-253.@*METHODS@#Participants aged 40 years and over, with moderate to severe COPD, were recruited into this 12-week study. The primary outcome measures were feasibility (acceptability of the intervention and attendance/adherence to the trial) and safety (adverse events, AEs). All participants received the MET and PR therapies. Participants and assessors were unblinded. Semi-standardized MET was delivered on 6 occasions (a maximum of once per week) at the hospital directly before a PR session. Participants undertook PR sessions as per the hospital program at a frequency of two days per week for 8 weeks. Participants were contacted 4 weeks after their final MET treatment via a telephone call to assess acceptability of the intervention.@*RESULTS@#Thirty-three participants were enrolled, with a median age of 74 years (range 45-89 years). The median number of MET sessions that participants attended was 5 (range 0-6) out of a possible 6 sessions (83% attendance). At follow-up, participants overwhelmingly enjoyed the MET treatment with some subjectively reporting improved breathing. There were no major AEs related to the intervention, with the majority of AEs classified as expected events related to COPD exacerbations.@*CONCLUSION@#It is feasible to implement a manual therapy protocol using MET as an adjunct to PR in a hospital setting. Recruitment rates were satisfactory and there were no AEs related to the MET component of the intervention.

Feasibility Study of Beam Angle Optimization Based on Scripts in Automated-planning for Liver Cancer / 中国医疗器械杂志

OBJECTIVE@#To study the feasibility and potential benefits of beam angle optimization (BAO) to automated planning in liver cancer.@*METHODS@#An approach of beam angle sampling is proposed to implement BAO along with the module Auto-planning in treatment planning system (TPS) Pinnacle. An in-house developed plan quality metric (PQM) is taken as the preferred evaluating method during the sampling. The process is driven automatically by in-house made Pinnacle scripts both in sampling and scoring. In addition, dosimetry analysis and physician's opinion are also performed as the supplementary and compared with the result of PQM.@*RESULTS@#It is revealed by the numerical analysis of PQM scores that only 15% patients whose superior trials evaluated by PQM are also the initial trials. Gantry optimization can bring benefit to plan quality along with auto-planning in liver cancer. Similar results are provided by both dose comparison and physician's opinion.@*CONCLUSIONS@#It is possible to introduce a full automated approach of beam angle optimization to automated planning process. The advantages of this procedure can be observed both in numerical analysis and physician's opinion.

Patient Acceptance of Telemedicine in Urogynecology Consultations - A Cross-Sectional Study Performed at a Brazilian Public Institution / Aceitação de telemedicina em consultas de uroginecologia: Estudo transversal em uma instituição pública brasileira

Abstract Objective To evaluate the acceptance of telemedicine and determine its associated factors in an urogynecology outpatient clinic of a public hospital in Brazil. Methods The present was a cross-sectional study performed between June and November 2020. The included patients had their elective appointments postponed due to the coronavirus disease 2019 (COVID-19) pandemic. The variables considered regarding the acceptance of telemedicine were: urogynecologic diagnosis, age, level of schooling, place of residence, access to the internet, type of device used, frequency of internet use, and use of social media platforms. The categorical variables were described by their absolute and relative frequencies. The association among variables was evaluated through the Fisher exact test, and univariate and multivariate analyses, considering the acceptance of telemedicine as the dependent variable. Results A total of 225 patients were listed, and 182 agreed to participate. The mean age was 59 years old, 81.3% of the patients had access to the internet, and 87.3% of them accepted telemedicine. There were statistically significant associations regarding the acceptance of telemedicine and high levels of schooling (p< 0.01), internet access (p< 0.01), daily use of the internet (p< 0.01), access through personal mobile phone (p< 0.01), and access through the participant's own residence (p< 0.01). In the univariate and multivariate analyses, only high levels of schooling were associated with the acceptance of telemedicine (Adjusted odds ratio: 4.82; 95% confidence interval = 1.59-14.65). Conclusion Most of the urogynecology patients of a public hospital in a developing country accepted telemedicine. Internet access and level of schooling were the factors associated with the acceptance of telemedicine in urogynecology.

Esofagectomía con linfadenectomía guiada por fluorescencia con verde de indocianina en cáncer de esófago. Experiencia inicial en la Argentina / Esophagectomy with lymphadenectomy guided by fluorescence imaging with indocyanine green in esophageal cancer. Initial experience in Argentina

RESUMEN Antecedentes: en la última década ha comenzado a investigarse el uso de la captación de fluorescencia mediante luz infrarroja para la visualización de ganglios linfáticos en tumores de estómago y esófago. Objetivo: evaluar la factibilidad de la evaluación del drenaje linfático de cáncer de esófago mediante el uso de fluorescencia y verde de indocianina (ICG). Material y métodos: se realizó un estudio prospectivo que incluyó pacientes con tumores de la unión gastroesofágica resecables (estadios I, II y III). Antes de comenzar la cirugía se inyectaron por endoscopia 4 mL de ICG doblemente diluida en agua estéril (1,25 mg/mL = 5 mg) en la submucosa del esófago en los cuatro cuadrantes (1 mL por cuadrante) alrededor del tumor. Resultados: se incluyeron en total 6 pacientes. En todos ellos se logró identificar el drenaje linfático del tumor hacia la primera estación ganglionar: en 6/6 (100%), el drenaje linfático con fluorescencia se detectó en las estaciones ganglionares N°s 3 y 7 (curvatura menor y arteria gástrica izquierda). En ningún paciente se identificó fluorescencia en ganglios mediastinales. Conclusión: la visualización del drenaje linfático de tumores de la unión gastroesofágica mediante el uso de fluorescencia con ICG es factible.

ABSTRACT Background: Over the past decade, fluorescence imaging with infrared light has been used to visualize lymph nodes in tumors of the stomach and esophagus. Objective: The aim of our study was to evaluate the feasibility of evaluating lymphatic drainage in esophageal cancer using fluorescence and indocyanine green (ICG). Material and methods: We conducted a prospective study of patients with resectable tumors of the gastroesophageal junction (stage I, II and III). Before surgery, 4 mL of ICG double diluted in sterile water (1.25 mg/mL = 5 mg) were injected via endoscopy into the esophageal submucosa in the four quadrants (1 mL per quadrant) around the tumor. Results: A total of 6 patients were included. Lymphatic drainage from the tumor to the first lymph node station was identified in all patients: in 6/6 (100%), fluorescent lymphatic drainage was detected in nodal stations number 3 and 7 (lesser curvature and left gastric artery) Fluorescence was not identified in the mediastinal lymph nodes in any patient. Conclusion: Visualization of lymphatic drainage of gastroesophageal junction tumors to the lesser curvature nodes using fluorescence imaging is feasible.

Testes Ergométricos em Pacientes com Anemia Falciforme: Segurança, Viabilidade e Possíveis Implicações no Prognóstico / Exercise Testing In Patients with Sickle Cell Disease: Safety, Feasibility and Potential Prognostic Implication

Resumo Fundamento Pacientes com anemia falciforme (AF) têm risco aumentado de complicações cardiovasculares. O teste ergométrico é usado como marcador de prognóstico em uma série de doenças cardiovasculares. Entretanto, há uma escassez de evidências sobre exercícios em pacientes com AF, especialmente em relação à sua segurança, viabilidade e possível função prognóstica. Objetivos Usamos o teste em esteira máximo para determinar a segurança e a viabilidade do teste ergométrico em pacientes com AF. Além disso, os fatores associados à duração do exercício, bem como o impacto das alterações causadas pelo exercício em resultados clínicos, também foram avaliados. Métodos 113 pacientes com AF que passaram pelo teste ergométrico e por uma avaliação cardiovascular abrangente incluindo um ecocardiograma e os níveis do peptídeo natriurético do tipo B (BNP). O desfecho de longo prazo foi uma combinação de eventos incluindo morte, crises álgicas graves, síndrome torácica aguda ou internações hospitalares por outras complicações associadas â doença falciforme. A análise de regressão de Cox foi realizada para identificar as variáveis associadas ao resultado. Um p valor <0,05 foi considerado estatisticamente significativo. Resultados A média de idade foi de 36 ± 12 anos (intervalo, 18-65 anos), e 62 pacientes eram do sexo feminino (52%). A presença de alterações isquêmicas ao esforço e resposta pressórica anormal ao exercício foram detectadas em 17% e 9 % da´população estudada respectivamente. Dois pacientes apresentaram crise álgica com necessidade de internação hospitalar no período de 48 horas da realização do exame. Fatores associados à duração do exercício foram idade, sexo, velocidade máxima de regurgitação tricúspide (RT), e relação E/e', após a padronização quanto aos marcadores da gravidade da doença. Durante o período médio de acompanhamento de 10,1 meses (variando de 1,2 a 26), 27 pacientes (23%) apresentaram desfechos clínicos adversos. Preditores independentes de eventos adversos foram a concentração de hemoglobina, velocidade do fluxo transmitral tardio (onda A), e a resposta da PA ao exercício. Conclusões A realização de testes ergométricos em pacientes com AF, clinicamente estáveis, é viável. A duração do exercício estava associada à função diastólica e a pressão arterial pulmonar. A resposta anormal da PA foi um preditor independente de eventos adversos.

Abstract Background Patients with sickle cell disease (SCD) are at increased risk for cardiovascular complications. Exercise testing is used as a prognostic marker in a variety of cardiovascular diseases. However, there is a lack of evidence on exercise in SCD patients, particularly regarding its safety, feasibility, and possible prognostic role. Objectives We used the maximal treadmill test to determine safety and feasibility of the exercise testing in SCD patients. Additionally, the factors associated with exercise duration, as well as the impact of exercise-induced changes on clinical outcome, were also assessed. Methods One-hundred thirteen patients with SCD, who underwent exercise testing, were prospectively enrolled. A comprehensive cardiovascular evaluation, including echocardiography and B-type natriuretic peptide (BNP) levels, were obtained. The long-term outcome was a composite endpoint of death, severe acute painful episodes, acute chest syndrome, or hospitalization for other SCD-related complications. Cox regression analysis was performed to identify the variables associated with the outcome. A p-value<0.05 was considered to be statistically significant. Results The mean age was 36 ± 12 years (range, 18-65 years), and 62 patients were women (52%). Ischemic electrocardiogram and abnormal blood pressure (BP) response to exercise were detected in 17% and 9%, respectively. Two patients experienced pain crises within 48 hours that required hospitalization. Factors associated with exercise duration were age, sex, tricuspid regurgitation (TR) maximal velocity, and E/e' ratio, after adjustment for markers of disease severity. During the mean follow-up of 10.1 months (ranging from 1.2 to 26), the endpoint was reached in 27 patients (23%). Independent predictors of adverse events were hemoglobin concentration, late transmitral flow velocity (A wave), and BP response to exercise. Conclusions Exercise testing in SCD patients who were clinically stable is feasible. Exercise duration was associated with diastolic function and pulmonary artery pressure. Abnormal BP response was an independent predictor of adverse events.

A feasibility analysis of digital interface to transfer information during doctors' handovers / Uma análise de viabilidade de interface digital para transferência de informações durante a passagem dos médicos / Análisis de viabilidad de la interfaz digital para apoyar los traspasos de turnos medicos

Objective: To report the pre-deployment analysis of a digital system to transfer patient information during physicians' obstetric shift sessions. Methods: A literature review explored evidence concerning electronic handover applications in hospitals. A survey met local approaches used to shift changing and the expectations of managers' stakeholders. To explore local practices, we analyzed a sample 251 obstetric handovers. Finally, requirements for the system were listed, and end-users evaluated mockups of the proposed design. Results: From the literature review, easy-to-use and integration with existing systems were the most critical requests to achieve user adherence. The main system requirement was using the hospital infrastructure to ensure full access to the current medical record. Mockup validation by end-users pinpointed items to improve a complete implementation and the positive acceptance of prefilled structured entries. Conclusions: There are blockages to overcome deficits in the quality of the information in clinical handovers to safely transfer patient care between doctors' shifts.

A qualitative and quantitative study

Introducción. Las funciones del Comité de Ética Clínica (CEC) son educativas, normativas, consultivas, mediadoras y reflexivas. Como cualquier servicio de salud, las consultas de casos a un CEC deben ser sujetas a revisión y mejora de la calidad. Los objetivos fueron evaluar la factibilidad, la efectividad y la satisfacción de las recomendaciones ético-asistenciales dadas por el CEC, y evaluar su impacto en el equipo tratante y en la familia. Población y métodos. Estudio descriptivo, retrospectivo, cualicuantitativo, de casos clínicos presentados en el Comité de Ética Clínica del hospital desde el 1 de enero de 2013 hasta el 31 de diciembre de 2017, según datos del libro de actas, historias clínicas, registros de la Oficina de Comunicación a Distancia y entrevistas semiestructuradas al equipo de salud. Resultados. Se analizaron 108 casos (106 pacientes), 73 casos con encuesta y registros, y 35 solamente con registros. Los motivos principales más frecuentes de consulta fueron los siguientes: adecuación del esfuerzo terapéutico (46/42,6 %), compromiso neurológico grave (15/13,9 %), calidad de vida del paciente (11/10,2 %), conflictos entre el paciente, la familia y el sistema de salud (7/6,5 %), y rechazo del tratamiento por la familia (6/5,6 %). Se hallaron niveles altos de satisfacción (> 95 %) y niveles moderados de factibilidad (> 74 %) y efectividad (> 85 %). Solo en 50/108 casos (46,3 %) quedó registro en la historia clínica de la consulta al CEC y el 44 % de los profesionales opinó que la consulta tuvo un impacto positivo en la familia y en el paciente. Conclusiones. Los resultados contribuyeron a descubrir oportunidades de mejora, especialmente en la documentación y en la comunicación en el proceso de consulta.

Introduction. A clinical ethics committee (CEC) has educational, regulatory, advisory, mediation, and reflexive functions. As any health care service, the consults with the CEC should be subjected to review and quality improvement. The study objectives were to assess the feasibility, effectiveness, and satisfaction with the bioethical recommendations made by the CEC and assess their impact on the treating team and the patient's family. Population and methods. Descriptive, retrospective, qualitative, and quantitative study of clinical cases submitted to the hospital's CEC between January 1 st, 2013 and December 31, 2017 using data from the CEC minute book, medical records, registries from the Office for Remote Communication, and semi-structured interviews with health care team members. Results. A total of 108 cases (106 patients) were analyzed: 73 cases with survey and registries and 35 with registries only. The main most frequent reasons for consultation were adequacy of therapeutic effort (46/42.6%), severe neurological involvement (15/13.9%), patient's quality of life (11/10.2%), patient-family-health system conflict (7/6.5%), and family's refusal of treatment (6/5.6%).
