Older people's perceptions and experiences of older people with the Sit-to-stand activity: An ethnographic pre-feasibility study / Percepções e experiências de idosos com a atividade Sit-to-stand: Um estudo etnográfico de pré-viabilidade / Percepciones y experiencias de los adultos mayores con respecto a la actividad Sit-to-stand: Un estudio etnográfico de viabilidad previa

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.

Telehealth for Parkinson disease patients during the COVID-19 pandemic: the TeleParkinson study / Telesaúde para pacientes com doença de Parkinson durante a pandemia de COVID-19: o estudo TeleParkinson

Abstract Background Telemedicine allows Parkinson disease (PD) patients to overcome physical barriers to access health care services and increases accessibility for people with mobility impairments. Objective To investigate the feasibility indicators of a telehealth intervention for PD patients, including patient recruitment, attendance, technical issues, satisfaction, and benefits on levels of physical activity and sleep. Methods We conducted a single-center, single-arm study of telehealth video consultations using WhatsApp (Meta Platforms, Inc., Menlo Park, CA, USA). Also, we collected the feasibility indicators as the primary endpoints. All the patients in the study were previously evaluated in person by the same team. Results Patient recruitment, attendance, and technical issues rates were 61.3%, 90.5%, and 13.3%, respectively, with good scores of patient acceptance and satisfaction with the study intervention. The telehealth intervention improved physical activity, including the number of walks for at least 10 continuous minutes (p = 0.009) and the number of moderate-intensity activities lasting at least 10 continuous minutes (p = 0.001). The Pittsburgh sleep quality index (PSQI) scores also improved for one of its components: perceived sleep duration (p < 0.001) and for total Pittsburgh score (p < 0,001). The average travel time saving was 289.6 minutes, and money-saving was R$106.67 (around USD 18; almost 10% of the current minimum wage in Brazil). Conclusions Direct-to-patient telehealth video consultations proved to be feasible and effective and had a positive impact on physical activity levels and sleep in PD patients.

Progress of mesenchymal stem cell-derived exosomes for management of preeclampsia / 中华围产医学杂志

Pre-eclampsia is a common complication of pregnancy that can result in serious consequences for mother and child health, but there are currently no established therapeutic options. Mesenchymal stem cell-derived exosomes (MSC-exos) are nanoparticles carrying bioactive substances such as proteins, lipids, and nucleic acids, and serve as a medium of intercellular communication. MSC-exos are involved in many important physiological processes, including immunological regulation, cell proliferation and migration, and angiogenesis, thereby play an important role in tissue repair and potentially clinical treatment strategies. In recent years, the treatment strategies of MSC-exos have become an emerging hot topic in the management of ischemic diseases, immune dysfunction, inflammatory diseases, and other fields. We review the advantages and challenges of MSC-exos as a new acellular therapy strategy as well as the feasibility of MSC-exos in managing preeclampsia, from its biological role in the important pathogenesis of preeclampsia, such as trophoblastic and endothelial cell dysfunction, immune imbalance at the maternal-fetal interface, and oxidative stress, and summarize the progress of animal experimental research in this field.

Twelve-section ultrasonic screening diagnosis method for neonatal complex congenital heart disease in primary hospitals at county level / 中华围产医学杂志

Objective:To investigate the feasibility of "twelve-section ultrasonic screening diagnosis method" in screening for neonatal complex congenital heart disease (CHD) in primary hospitals.Methods:This is a prospective study. A total of 71 580 newborns were screened for CHD using the "twelve-section ultrasonic screening diagnosis method" from four pilot units in Hebei province, which were Bo'ai Hospital of Huanghua Development Zone, Traditional Chinese Medicine Hospital of Fengning County, Maternity & Child Healthcare Hospital of Tang Country, and Maternity & Child Healthcare Hospital of Rongcheng Country, from November 2015 to December 2019. Another 262 children with CHD were enrolled, including 39 with complex CHD. These cases received ultrasonography at four pilot units above and then were transferred to CHD Screening Diagnosis and Treatment Center of Hebei Children's Hospital (our center) prior to the implementation of "twelve-section ultrasonic screening diagnosis method" from June 2012 to June 2014, who were all confirmed by surgery. Set the diagnosis results of our center as the gold standard, the sensitivity, specificity, and diagnostic consistency rate in screening for complex CHD cases were calculated. Receiver operating characteristic (ROC) analysis and Chi-square test were used to compare and analyze the sensitivity for screening neonatal complex CHD before and after implementing the method. The screening results of complex CHD after implementing the method between the pilot units and our center as well as between the four pilot units were compared and analyzed using Chi-square test. Results:A total of 553 (0.77%) CHD cases were detected by the "twelve-section ultrasound screening diagnosis method", including 66 cases of complex CHD and 487 cases simple CHD. Among the cases screened using the method, there were three false negative cases (one case with total anomalous pulmonary venous drainage, one with abnormal coronary artery originating from pulmonary artery, and one with atresia of distal to the left subclavian artery, aortic arch and left aortic arch of double-arch), one false positive case (false echo loss of aortopulmonary septal that was misdiagnosed as aortopulmonary septal defect), five cases of misdiagnosis (one common pulmonary venous atresia case that was misdiagnosed as total anomalous pulmonary venous drainage, one persistent stenosis of the fifth aortic arch that was misdiagnosed as coarctation of aorta, one pulmonary artery sling that was misdiagnosed as absence of left pulmonary artery, one severe coarctation of aorta that was misdiagnosed as interruption of aortic arch, and one aortic isthmus atresia that was misdiagnosed as coarctation of aorta), and all were complex CHD cases. A total of 68 cases (12.3%) of complex CHD were confirmed by our center. The overall sensitivity, specificity, and diagnostic consistency rate of screening were 95.6% (65/68), 99.8% (484/485), and 86.8% (59/68), respectively and the area under ROC curve was 0.98. Before the implementation, the overall sensitivity, specificity, and diagnostic coincidence rates of ultrasonic screening for complex CHD were 69.2%(27/39), 95.5%(213/223), and 61.5% (24/39), respectively, and the area under ROC curve was 0.82. The sensitivity of complex CHD screening was significantly increased after implementing the method ( χ2=14.28, P<0.05). There was no significant statistical significance in the sensitivity for screening complex CHD after the implementation between the pilots and our center or between the four pilots (all P>0.05). Conclusions:"Twelve-section ultrasonic screening diagnosis method" is suitable for the screening of neonatal complex CHD in hospitals at the county level. However patients with some special types of complex CHD are recommended to be transferred for a more accurate diagnosis.

Physical activity supported by mobile technology program (PAT-Back) for older adults with back pain at primary care: a feasibility study protocol

Abstract Aim: Low back pain (LBP) is disabling in older adults. Although physical activity interventions positively affect LBP, older adults are underrepresented in the literature. We aim to investigate the feasibility of conducting a study to evaluate a primary care program of exercise therapy and pain education, supported by mobile technology, for older adults with chronic LBP (compared to best practice advice). Methods: In this parallel, two-arm randomized pilot trial, we will recruit adults aged 60 years and older with chronic LBP. The experimental group (Physical Activity supported by low-cost mobile technology for Back pain-PAT-Back) will consist of an 8-week group exercise program based on pain education, exercises, graded activities, and in-home physical activity. Text messages will be sent to promote adherence to home exercises. The control group will receive an evidence-based educational booklet given during one individual consultation. Outcomes will include recruitment rate, adherence and retention rates, level of understanding of the intervention content, perception of the utility of mobile technology, compliance with the accelerometer in a sub-sample of patients, and adverse events. Discussion: The results of this study will form the basis for a large randomized controlled trial. This innovative approach to managing LBP in the primary care setting for older adults, if proven to be effective, can bring an important advance in the knowledge of chronic LBP management to this population.

A exequibilidade foi identificada considerando-se parâmetros preestabelecidos. Identificaram-se 225 sujeitos com diferença de franjas na região dorsal, e 224 com diferença de franjas na cintura escapular. Quanto à exequibilidade, a amostra foi examinada em sete dias e não houve dificuldades na execução da técnica, no processamento das imagens e nos materiais requeridos. Considerou-se a TMS exequível para triagens populacionais, permitindo exames periódicos em larga escala. A TMS pode ser uma estratégia na implementação de programas de saúde pública na escola, objetivando a melhora da qualidade de vida.

This study aimed to examine the feasibility of the Shadow Moiré Technique (SMT) in carrying out periodic school screenings and to identify the prevalence of postural disorders in students from a public school in Rio de Janeiro. The sample was comprised of 304 students. The SMT exam was based on the difference in the number of fringes in the dorsal and scapulothoracic regions. The feasibility of the SMT was identified based on predetermined parameters. Two hundred and twenty-five subjects were identified with fringe difference in the dorsal region and 224 were identified with fringe difference in the scapulothoracic region. Regarding feasibility, the sample was examined over the period of 7 days. There were no difficulties in obtaining the materials, in the use of the technique or in the processing of the images. SMT was considered feasible to screen the population and it allows for large-scale periodic examination. The SMT can be a strategy for implementing public health programs at school aiming at improving the quality of life.

Immediate outcomes of aortic valve neocuspidization with glutaraldehyde-treated autologous pericardium: a multicenter study

Abstract Objective: To determine the feasibility of aortic valve neocuspidization (AVNeo) with glutaraldehyde-treated autologous pericardium. Methods: One hundred and seventy (170) AVNeo (84 males/86 females) were performed from January 2017 through March 2019 in three centers. All the records were prospectively collected and retrospectively reviewed. Results: Most of the patients were older than 60 years and over 95% were operated for aortic stenosis. Preoperatively, pressure gradients were 69.9±21.3 mmHg for patients with aortic stenosis, and the surgical annular diameter was 21.0±2.0 mm for all patients. Effective orifice area (EOA) and indexed EOA (iEOA) averaged 0.7±0.3 cm2 and 0.4±0.2 cm2/m2 for patients with aortic stenosis before surgery, respectively. There was no conversion to prosthetic aortic valve replacement. Eight patients needed reoperation for bleeding, but no patient needed reoperation due to early infective endocarditis. There were five in-hospital deaths due to noncardiac cause. Compared to preoperative echocardiographic measurements, postoperative peak pressure gradient decreased significantly (-58.7±1.7 mmHg; P<0.001) and reached 11.2±5.6 mmHg, and mean pressure gradient also decreased significantly (-36.8±1.1 mmHg; P<0.001) and reached 6.0±3.5 mmHg. Accordingly, EOA and iEOA increased significantly 2.0 cm2 and 1.0 cm2/m2 (both P<0.001) to reach 2.7±0.6 cm2 and 1.4±0.3 cm2/m2 after surgery, respectively, with minimal significant aortic regurgitation (0.6% > mild). Conclusion: AVNeo is feasible and reproducible with good clinical results. Hemodynamically, AVNeo produces immediate postoperative low-pressure gradients, large EOA, and minimal regurgitation of the aortic valve. Further studies are necessary to evaluate mid- and long-term evolution.

Acupuncture in living liver and kidney donors: a feasibility study / 中西医结合学报

OBJECTIVE@#The purpose of this study was to test the feasibility of integrating acupuncture into the routine care of living liver and kidney donors during the process of donation and recovery.@*METHODS@#This is a pilot study on the feasibility of a brief acupuncture intervention for living liver and kidney donors. Participants received acupuncture immediately prior to organ donation surgery, every day as inpatients, while recovering from donation, and at a 2-week follow-up. Prior to surgery, questionnaires were completed on acupuncture outcome expectations and the State-Trait Anxiety Inventory. After participating, those who received acupuncture provided feedback. Following the active intervention, a retrospective chart review was conducted, using donors who did not receive acupuncture as a comparison cohort.@*RESULTS@#Forty donor candidates were approached and recruited, 32 consented and ultimately 25 donors participated in the acupuncture intervention (15 of kidney, 10 of liver), 68% female, and 88% Caucasian; only one had prior experience with acupuncture. Participants received an average of 4 sessions while inpatient (range 2-8). Those who expected acupuncture to be more helpful prior to the intervention reported lower inpatient pain scores (P = 0.04). Qualitative feedback from patients was predominantly positive, indicating acupuncture was helpful for relaxation and pain. However, a few patients reported feeling overburdened during postdonation recovery, and that the study was viewed as additional obligation.@*CONCLUSION@#Preliminary findings suggest it is feasible to integrate acupuncture into inpatient recovery for living organ donation. Tailoring interventions to the specific needs of patients is important to address ongoing concerns. Larger studies are needed to further ascertain benefits of peri-operative acupuncture.

Robotic-assisted laparoscopic myomectomy: the feasibility in single-site system

OBJECTIVE: To evaluate the feasibility of robotic single-site myomectomy (RSSM). METHODS: Medical records of 355 consecutive women who underwent robotic-assisted laparoscopic myomectomy were retrospectively reviewed. Clinical characteristics were compared between multi-site and single-site systems. After 1:1 propensity score matching for the total myoma number, largest myoma size, and total tumor weight (105 women in each group), surgical outcomes were also compared between the 2 systems. RESULTS: A total of 105 (29.6%) and 250 (70.4%) women underwent RSSM and robotic multi-site myomectomy (RMSM), respectively. RSSM was more commonly performed in women with lower body mass index (21.6 vs. 22.5 kg/m2, P=0.014), without peritoneal adhesions (7.6% vs. 24.8%, P < 0.001), and less (2.6 vs. 4.6, P < 0.001) and smaller (6.3 vs. 7.7 cm, P < 0.001) myomas compared to RMSM. After propensity score matching, the largest myoma size (P=0.143), total myoma number (P=0.671), and tumor weight (P=0.510) were not significantly different between the 2 groups. Although the docking time was significantly longer in the RSSM group (5.1 vs. 3.8 minutes, P=0.005), total operation time was similar between RSSM and RMSM groups (145.9 vs. 147.3 minutes, P=0.856). Additionally, hemoglobin decrement was lower in the RSSM group than in the RMSM group (1.4 vs. 1.8 g/dL, P=0.009). No surgical complication was observed after RSSM, while 1 ileus and 2 febrile complications occurred in women that underwent RMSM (0% vs. 2.9%, P=0.246). CONCLUSION: Although RMSM is preferred for women with multiple large myomas in real clinical practice, RSSM seems to be a feasible surgical method for less complicated cases, and is associated with minimal surgical morbidity.

Prospective study on the safety and feasibility of early ileostomy closure 2 weeks after lower anterior resection for rectal cancer

PURPOSE: Transient loop ileostomies in rectal cancer surgery are generally closed after 2 or more months to allow adequate time for anastomotic healing. Maintaining the ileostomy may cause medical, surgical, or psychological complications; it also reduces the quality of life, and increase treatment costs. We performed this study to evaluate the safety and feasibility of early ileostomy closure 2 weeks postoperatively. METHODS: If a patient who underwent total mesorectal excision had 2 or more risk factors for anastomotic leakage, a loop ileostomy was created. After confirmation of intact anastomosis via sigmoidoscopy and proctography 1 week postoperatively, the patient was enrolled and ileostomy was closed 2 weeks postoperatively. The primary endpoint was the frequency of complication after ileostomy repair. RESULTS: Thirty patients were enrolled in the study and 6 were excluded due to anastomotic leakage. Except for 1 case of wound infection (4.2%), no patient experienced any complication including newly developed leakage after the ileostomy closure. The mean duration to repair was 13.1 days (range, 8–16 days) and mean duration to the start of adjuvant treatment after radical surgery was 5.37 weeks (range, 3.0–8.1 weeks). CONCLUSION: Transient loop ileostomy, which is confirmed to be intact endoscopically and radiologically, can be safely closed 2 weeks postoperatively without requiring a significant delay in adjuvant chemotherapy.

The feasibility of sentinel lymph node biopsy after axillary lymph node clinical complete response / 中国医师杂志

Objective The use of sentinel lymph node biopsy (SLNB) following neoadjuvant chemotherapy (NAC) in patients presenting with clinically positive lymph nodes remains controversial.This study is aimed to invest if it is feasible to perform SLNB after NAC in case that axillary lymph nodes turned to clinical negative.Methods A computer-aided search of the literature regarding SLNB in clinically nodepositive breast cancer treated with NAC was carried out to identify the false negative rate (FNR),sentinel lymph node identification rate (IR).Results 16 articles were used in the analysis yielding 1 579 patients.The pooled estimate of FNR,IR,sensitivity and overall accurancy was 13.6％,91％,85.7％,and 92.8％,respectively.Conclusions SLNB after NAC in lymph node-positive patients,whose axillary lymph node was clinical negative after NAC,results in reasonably IR,but FNR was still high to be accepted.More refined patient selection and optimal techniques are expected to lower the FNR in this patient population.

Effectiveness and feasibility of early essential newborn care during term cesarean section / 中华围产医学杂志

Objective To explore the effects of early essential newborn care (EENC) on short-term maternal and neonatal health and to evaluate the satisfaction and acceptability of both patients and medical staff in the operating room regarding the implementation of EENC during term cesarean section(CS). Methods Two hundred gravidas who underwent CS in Wenzhou Medical University Affiliated Women and Children Hospital from January 2018 to April 2018 were recruited in this prospective study. According to the odd or even number of their medical records, these women were randomly divided into EENC or control group, 100 in each. EENC was offered to those in the EENC group immediately after birth, including drying the newborn immediately and thoroughly, mother–infant skin-to-skin contact at least 90 min and initiating the first breastfeeding, and delayed cord clamping until l-3 min after birth. Routine neonatal care was provided to the control group, including regular drying, insufficient skin-to-skin contact and cord clamping within 1 min after birth. Differences were compared between the two groups in the incidence of abnormal pulse, low oxygen saturation, hypothermia and mild asphyxia from the neonatal aspect and the incidence of postpartum hemorrhage and early initiation of breastfeeding from the maternal aspect. The acceptability and satisfaction of all the participants and the medical staff were also analyzed. t-test and Chi-square test were used as statistical methods. Results All of the 200 participants were finally analyzed. In the EENC group, the incidence of neonatal hypothermia [2% (2/100) vs 13% (13/100), χ2=8.721, P=0.003] and maternal postpartum hemorrhage [1% (1/100) vs 6% (6/100), χ2=5.701, P=0.035] were lower comparing to the control group, while the initiation rate of early breastfeeding was higher [56% (56/100) vs 5% (5/100), χ2=61.352, P<0.001]. There was no significant difference in the incidence of neonatal abnormal pulse, low oxygen saturation or mild asphyxia between the two groups (all P>0.05). The scores of maternal satisfaction (24.6±0.4 vs 23.4±1.9, t=6.443, P=0.001) and acceptability (24.3±0.5 vs 23.5±1.4, t=5.436, P=0.001) in the EENC group were also significantly higher than those in the control. For the obstetric operation team, the acceptability scores among obstetricians (22.6±0.8 vs 21.6±1.3, t=2.379, P=0.019), instrument nurses (23.2±0.9 vs 21.3±1.1, t=13.592, P<0.001) and anesthetists (22.6±0.9 vs 21.5±1.7, t=5.625, P=0.001) in the EENC group were higher than those in the control group. However, no significant difference was observed in the acceptability among rounding nurses between the two groups (P=0.086). Conclusions EENC during CS could stabilize the neonatal temperature, reduce postpartum hemorrhage, promote early breastfeeding and improve the maternal satisfaction as well as the acceptability of both obstetric operation team and puerperae. There is a clinical significance to promote EENC during CS.
