Resilience building among Chinese family caregivers of older people with Parkinson's disease in Shanghai.

Despite a rapid increase in people with Parkinson's disease (PD) in China, studies focusing on caregiver burden remain scarce. Challenges faced by caregivers in other Asian societies are also underexplored in the PD-related research field. To addresses this gap, this study drew on the theory of resilience and examined the caregiving experiences of Chinese family caregivers for older people with PD. We conducted participant observation and semi-structured interviews with 15 family caregivers of older people with PD in Shanghai in 2018. We used thematic analysis to identify key patterns of stressors and factors affecting the capacity of caregivers to address burdens. Our analysis shows that stressors faced by Chinese PD caregivers included physical limitations, psychological and emotional problems, reduction in social connections, financial burden and lack of information and knowledge. Three levels of factors-personal, social and structural-played different roles in resilience among Chinese PD caregivers. However, resilience was unevenly developed among PD caregivers across gender, kinship, residential status and generation. Our study provides novel empirical evidence about the burden on Chinese PD caregivers. It can inform policymakers and social workers as they develop a holistic understanding of promoting resilience building in this rapidly growing group. Our study also enriches cross-cultural knowledge about factors contributing to caregivers' resilience building in Asian societies.

Pulse oximetry waveform: A non-invasive physiological predictor for the return of spontaneous circulation in cardiac arrest patients ---- A multicenter, prospective observational study.

OBJECTIVE: This study aimed to investigate the predictive value of pulse oximetry plethysmography (POP) for the return of spontaneous circulation (ROSC) in cardiac arrest (CA) patients. METHODS: This was a multicenter, observational, prospective cohort study of patients hospitalized with cardiac arrest at 14 teaching hospitals cross China from December 2013 through November 2014. The study endpoint was ROSC, defined as the restoration of a palpable pulse and an autonomous cardiac rhythm lasting for at least 20 minutes after the completion or cessation of CPR. RESULTS: 150 out-of-hospital cardiac arrest (OHCA) patients and 291 in-hospital cardiac arrest (IHCA) patients were enrolled prospectively. ROSC was achieved in 20 (13.3%) and 64 (22.0%) patients in these cohorts, respectively. In patients with complete end-tidal carbon dioxide (ETCO2) and POP data, patients with ROSC had significantly higher levels of POP area under the curve (AUCp), wave amplitude (Amp) and ETCO2 level during CPR than those without ROSC (all p < 0.05). Pairwise comparison of receiver operating characteristic (ROC) curve analysis indicated no significant difference was observed between ETCO2 and Amp (p = 0.204) or AUCp (p = 0.588) during the first two minutes of resuscitation. CONCLUSION: POP may be a novel and effective method for predicting ROSC during resuscitation, with a prognostic value similar to ETCO2 at early stage.

The impact of SARS and COVID-19 on major trauma in Hong Kong.

BACKGROUND: The coronavirus disease 2019 (COVID-19) pandemic has been enormously disruptive and harmful to people around the world, but its impact on other illnesses and injuries has been more variable. To evaluate the ramification of infectious disease outbreaks on major traumatic injuries, we compared changes in the incidence of major trauma cases during the 2003 Severe Acute Respiratory Syndrome (SARS) period with COVID-19 in 2020. METHODS: Data were analyzed from the trauma registry of a major, tertiary-care teaching hospital in Hong Kong. Patients presenting with major traumatic injuries during the first six months of 2001-03 and 2018-20 were retrieved for analysis. Patient characteristics, injury mechanism, admitting service, and emergency department (ED)/hospital lengths of stay (LOS) were recorded. Raw and adjusted survival rates (using the modified Trauma Injury Severity Score (TRISS)) were recorded. RESULTS: The number of trauma cases fell dramatically during 2003 and 2020 compared with previous years. In both 2003 and 2020, the number of trauma registry patients fell by 49% in April (compared to the preceding reference years of 2001/02 and 2018/19, respectively). Patient characteristics, treatments, and outcomes were also different during the outbreak years. Comparing 2003 to 2020 relative to their respective reference baselines, the percentages of injuries that happened at home, patients without co-morbidities, and patients' mean age all increased in 2003 but decreased in 2020. Work-place injuries drastically dropped in 2003, but not in 2020. Average ED LOS dropped in 2003 by 36.4 min (95% CI 12.5, 60.3) but declined by only 14.5 min (95% CI -2.9, 32.1) in 2020. Both observed and expected 30-day mortality declined in 2020 vs. 2003 (observed 4.5% vs. 11.7%, p = 0.001, OR 0.352, 95% CI 0.187, 0.661) (expected 4.5% vs 11.6%, p = 0.002, OR 0.358, 95% CI 0.188, 0.684). CONCLUSION: Major trauma cases dropped by half during both the peak of the 2003 SARS and 2020 COVID-19 pandemics in Hong Kong, suggesting a trend for future pandemic planning. If similar findings are seen at other trauma centers, proactive personnel and resource allocations away from trauma towards medical emergency systems may be more appropriate for future pandemics.

Morbidity and mortality risk factors in emergency department patients with Acinetobacter baumannii bacteremia.

BACKGROUND: Acinetobacter baumannii (AB) bacteremia is an increasingly common and often fatal nosocomial infection. Identification of morbidity and mortality risk factors for AB bacteremia in emergency department (ED) patients may provide ways to improve the clinical outcomes of these patients. METHODS: The records for 51 patients with AB bacteremia and 51 patients without AB infection were collected and matched in a retrospective case-control study between 2013 and 2015 in a single-center ED. Risk factors were analyzed by Chi-square and multivariate logistic regression statistical models. RESULTS: A significant risk factor for morbidity was the presence of a central venous catheter (CVC) (P<0.001). The mortality rate for the 51 patients with AB bacteremia was 68.6%. Risk factors for mortality were the presence of a CVC (P=0.021) and an ED stay longer than two weeks (P=0.015). CONCLUSION: AB infections lead to high morbidity and mortality. The presence of a CVC was associated with higher morbidity and mortality in patients with AB bacteremia. Avoiding CVC insertions may improve outcomes in ED patients with AB bacteremia.

Intensive insulin therapy versus plasmapheresis in the management of hypertriglyceridemia-induced acute pancreatitis (Bi-TPAI trial): study protocol for a randomized controlled trial.

BACKGROUND: It is widely agreed that triglyceride (TG)-lowering therapy is imperative in early hypertriglyceridemia-induced acute pancreatitis (HTG-AP). Intravenous insulin with or without heparin, and plasmapheresis are available regimens. However, there is no consensus on first-line therapy. METHODS/DESIGN: The Bi-TPAI trial is a multicenter, parallel group, randomized, controlled, non-inferiority trial in patients with early HTG-AP. The Bi-TPAI trial will include 220 patients with HTG-AP from 17 large tertiary hospitals in China. Patients assigned to the intensive insulin group will be administered an intravenous continuous infusion of regular human insulin at a rate of 0.1 units/kg·h and up to 0.3 units/kg·h. Patients allocated to the plasmapheresis group will receive standard-volume plasmapheresis. The primary endpoint is the time it takes for the TG level to reduce to 500 mg/dl. The secondary endpoints are ICU and hospital lengths of stay, 28-day mortality, severity of HTG-AP, incidence of hypoglycemia, HTG-AP complications, and cost-effectiveness. DISCUSSION: The Bi-TPAI trial will prove that intensive insulin therapy is non-inferior to plasmapheresis. Intensive insulin therapy should be an effective, safe, available, and cheaper triglyceride-lowering therapy for hypertriglyceridemia-induced acute pancreatitis. TRIAL REGISTRATION: ClinicalTrials.gov, NCT03342807 . Registered on 5 Nov 2017.

An Exploratory Study of Sectra Table Visualization Improves the Effectiveness of Emergency Bedside Echocardiography Training.

OBJECTIVES: Echocardiography is an essential tool in emergency medicine, and its training is the most challenging of all types of bedside ultrasound (US) training. This study investigated the effectiveness of the Sectra Table (Sectra AB, Linköping, Sweden), an anatomy visualization and collaboration tool, in improving the quality of echocardiography training for emergency medicine physicians. METHODS: We conducted an exploratory prospective observational study from 2015 to 2017 and enrolled 66 trainees who participated in a 2.5-day bedside US course organized by the emergency department (ED) of Peking Union Medical College Hospital. The study participants underwent 2 different training programs: the first group received standard training, and the second group was trained with Sectra Table experiences integrated into the echocardiography training curriculum. After the training sessions, both groups were evaluated for their hands-on echocardiography performance. RESULTS: The new training program with the Sectra Table significantly increased trainees' self-confidence in performing bedside echocardiography. The Sectra Table trainees had a higher performance rating than the trainees in the traditional program, with a mean total assessment score of 40.5 versus 26.5 for traditional training (P < .01). The improved performance was evident for all subcategories of echocardiography. The higher performance rating of the Sectra Table trainees was also statistically significant after adjusting for confounders, including prior training experiences, baseline confidence in independently performing ED US examinations, the number of ED US examinations performed, years in ED practice, and physician seniority. CONCLUSIONS: Our analysis suggests that integrating the Sectra Table into echocardiography training may improve the effectiveness of training programs.

Evaluating and assessing the prevalence of bedside ultrasound in emergency departments in China.

BACKGROUND: To survey the prevalence of bedside ultrasound assessment in emergency departments (EDs) in China. METHODS: We designed an online survey for emergency physicians based in the China. The questionnaire included sixteen items querying common ED bedside ultrasound practices. Respondents were recruited via weblinks sent through social media and a popular Chinese emergency medicine website. Survey data was collected from April through June, 2016. RESULTS: Four hundred and twenty-eight physicians responded to this survey; more than 80% of respondents reported working clinically in the ED. Ninety-eight percent of respondents agreed on the clinical importance and value of bedside ultrasound. However, less than half of participants' EDs had ultrasound devices, and less than half of the respondents said they knew how to perform bedside ultrasound. Less than 20% of respondents reported having had formal training in bedside ultrasound. CONCLUSIONS: There is a strong interest in bedside ultrasound in Chinese EDs. Emergency physicians participating in this study considered bedside ultrasound a necessary skill, but, because there is a lack of training, most emergency physicians reported they did not know how to perform bedside ultrasonography. There is likely an acute desire and need for bedside ultrasound training for Chinese emergency physicians.

Biotech pilgrims and the transnational quest for stem cell cures.

Thousands of patients with incurable neurodegenerative conditions from more than 60 countries have sought fetal cell transplants in China since 2001. Drawing on 24 months of ethnographic fieldwork, I investigate these transnational encounters occurring in the realm of experimental medicine. Critiquing popular notions of "medical tourism," I develop the alternative concept of "biotech pilgrimage" to reveal how faith intertwines with technology, travel, and the political economies of health care and medical research in a global era. Insights from pilgrimage theory enable us to question assumptions of leisure embedded in claims of tourism while also exploring new biopolitical practices that extend beyond the borders of the nation-state. I also demonstrate how materialist visions of salvation underlie medical practice and contribute to China's rising influence as a global technological leader.
