Mediating effects of predictability between caregiving demands and caregiving consequences for persons living with dementia: A longitudinal study.

OBJECTIVES: The purpose of this study was to examine the role of predictability in the relationship between caregiving demands and caregiving consequences. DESIGN: This 2-year longitudinal survey study collected from self-report questionnaires. A convenience sample of family caregivers of older persons living with dementia were recruited from a neurology clinic. RESULTS: A total of 200 family caregivers were recruited to participate. Analysis indicated predictability was a partial mediator between caregiving demand and caregiver consequences of role strain, depressive symptoms and both physical and mental components of health-related quality of life at the 2-year follow. Predictability accounted for 25 %, 28.8 %, 15.3 % and 46.5 % of the relationship between caregiving demand and caregiving consequences of role strain, depressive symptoms, physical- and mental-health related quality of life, respectively. CONCLUSIONS: The contributions of caregiving demand to outcomes of caregiver consequences were in part due family caregivers perceived predictability for caregiving.

Use of consecutive transcutaneous oxygen measurement when assessing the need for revascularization and association with the outcomes of ischemic diabetic ulcers.

This study compared the ankle-brachial index (ABI) with transcutaneous oxygen pressure (TcPO2 ) in assessing peripheral vascular disease (PVD) prevalence in 100 diabetic foot ulcer (DFU) patients. Patients were categorized into vascular or nonvascular reconstruction groups and underwent both ABI and TcPO2 measurements four times over 6 months. Predictive validity for PVD diagnosis was analysed using the area under the receiver-operating characteristic curve (AUC). The study found TcPO2 to be a superior predictor of PVD than ABI. Among the DFU patients, 51 with abnormal TcPO2 values underwent vascular reconstruction. Only TcPO2 values showed significant pretreatment differences between the groups and increased post-reconstruction. These values declined over a 6-month follow-up, whereas ABI values rose. For those with end-stage renal disease (ESRD), TcPO2 values saw a sharp decrease within 3 months. Pre-reconstruction TcPO2 was notably lower in amputation patients versus limb salvage surgery patients. In conclusion, TcPO2 is more effective than ABI for evaluating ischemic limb perfusion and revascularization necessity. It should be prioritized as the primary follow-up tool, especially for ESRD patients.

Effects of Shared Decision-Making with a Patient Decision Aid for Postangiography Hemostasis Method Selection: A Randomized Controlled Trial.

PURPOSE: To evaluate the effects of shared decision-making (SDM) with a patient decision aid (PtDA) on hemostasis device selection and reduction of decisional conflicts in patients undergoing transfemoral angiography. MATERIALS AND METHODS: Patients undergoing angiography were randomized to receive either a standard explanation or the process aid of PtDA for choosing hemostasis devices. The decisional conflict was assessed using the 4-item Sure of myself; Understand information; Risk-benefit ratio; Encouragement (SURE) scale. Differences in demographic variables, clinical variables, and final choice of hemostasis devices were compared via univariate and multivariate logistic regression analyses. RESULTS: In total, 158 patients were included-80 in the PtDA group and 78 in the standard group. No difference was found between the 2 groups in terms of patient demographic and clinical variables. The PtDA group scored better on all questions of the SURE scale both individually and collaboratively (P <.001). PtDA intervention (P =.031) and reason for angiography (P =.0006) were the main variables that influenced patient hemostasis device choice in the univariate logistic regression analysis. Reason for angiography remained the only deciding factor that affected patient choice in the multivariate logistic regression analysis (P =.015). CONCLUSIONS: Step-by-step guidance and pictorial explanation with the assistance of PtDA led to improvements in patient knowledge but showed no significant impact in multivariate analysis for the influence on the choice of hemostasis device.

Cardioprotective potential of lithium and role of fractalkine in euthymic patients with bipolar disorder.

OBJECTIVE: Over a half century, lithium has been used as the first-line medication to treat bipolar disorder. Emerging clinical and laboratory studies suggest that lithium may exhibit cardioprotective effects in addition to neuroprotective actions. Fractalkine (CX3CL1) is a unique chemokine associated with the pathogenesis of mood disorders and cardiovascular diseases. Herein we aimed to ascertain whether lithium treatment is associated with favorable cardiac structure and function in relation to the reduced CX3CL1 among patients with bipolar disorder. METHODS: We recruited 100 euthymic patients with bipolar I disorder aged over 20 years to undergo echocardiographic study and measurement of plasma CX3CL1. Associations between lithium treatment, cardiac structure and function and peripheral CX3CL1 were analyzed according to the cardiovascular risk. The high cardiovascular risk was defined as (1) age ⩾ 45 years in men or ⩾ 55 years in women or (2) presence of concurrent cardiometabolic diseases. RESULTS: In the high cardiovascular risk group (n = 61), patients who received lithium as the maintenance treatment had significantly lower mean values of left ventricular internal diameters at end-diastole (Cohen's d = 0.65, p = 0.001) and end-systole (Cohen's d = 0.60, p = 0.004), higher mean values of mitral valve E/A ratio (Cohen's d = 0.51, p = 0.019) and superior performance of global longitudinal strain (Cohen's d = 0.51, p = 0.037) than those without lithium treatment. In addition, mean plasma levels of CX3CL1 in the high cardiovascular risk group were significantly lower among patients with lithium therapy compared with those without lithium treatment (p = 0.029). Multiple regression models showed that the association between lithium treatment and mitral value E/A ratio was contributed by CX3CL1. CONCLUSION: Data from this largest sample size study of the association between lithium treatment and echocardiographic measures suggest that lithium may protect cardiac structure and function in patients with bipolar disorder. Reduction of CX3CL1 may mediate the cardioprotective effects of lithium.

Cross-cultural adaptation and validation of the Traditional Chinese version of the Core Outcome Measures Index in patients with low back pain.

PURPOSE: This study aimed to carry out a cross-cultural adaptation of the Core Outcome Measures Index (COMI) for use in Traditional Chinese-speaking patients with low back pain (LBP) and to investigate its psychometric properties. METHODS: A total of 224 patients with LBP > 6 weeks who visited our spine center from May 2018 to May 2019 were included in the study. Patients completed a booklet of questionnaires including the following: (1) pain Numeric Rating Scale, (2) Oswestry Disability Index, (3) Roland-Morris Disability Questionnaire, (4) EuroQol-five dimension (EQ-5D), and (5) COMI. Patients were sent a second booklet (also containing a transition question to indicate any change in condition) to be completed again within one month after the first. Fifty-two patients did not receive any intervening treatment (group 1), while the other 172 patients received medical treatment (group 2) between the two questionnaires. RESULTS: The intraclass correlation coefficient (ICC) for the COMI summary score was 0.94 (95% CI 0.89-0.97); the standard error of measurement (SEM) was 0.41 and the minimum detectable change (MDC) score was 1.14. The COMI summary scores showed a low floor effect (1.8%) and ceiling effect (0.4%). All COMI item scores demonstrated the hypothesized correlations with their corresponding full-length questionnaires except for the pain item (correlation stronger than hypothesized). Standardized response means (SRM) for the COMI items in the treated group were between 0.58 and 1.30. Regarding the ability of the COMI change score to differentiate between good and poor outcomes, the area under the receiver operating characteristic (AUROC) curve was 0.77 [standard error (SE) 0.07, 95% confidence interval (CI) 0.68-0.84] and the minimal clinically important change (MCIC) score was ≥ 1.85 points. CONCLUSION: The Traditional Chinese COMI represents a practical and reliable tool for the assessment of Traditional Chinese-speaking patients with back problems.

Sleep quality mediates the relationship between lower urinary tract symptoms and health-related quality of life in women with type-II diabetes.

AIM: To examine the mediating effect of sleep quality on the relationship between lower urinary tract symptoms and health-related quality of life in women with type-II diabetes. DESIGN: A cross-sectional study. METHODS: A study questionnaire comprising three valid instruments was used to obtain data about lower urinary tract symptoms, sleep quality and physical and mental component summary health-related quality of life between July 2017 and December 2018 (n = 343). Pearson's correlation coefficients were estimated initially to examine the relationships between the three variables. Multiple regression models were tested using a regression-based approach Hayes PROCESS macro for SPSS to examine the significance of proposed mediation effects. RESULTS: Most participants experienced at least one urinary symptom (n = 268, 78.1%). The total number of types of lower urinary tract symptoms experienced by participants was significantly inversely correlated with physical and mental component summary health-related quality of life, and sleep quality. Participants' sleep quality was significantly correlated with physical and mental component summary health-related quality of life. The relationships of lower urinary tract symptoms with physical and mental component summary health-related quality of life were, respectively, fully and partially mediated by sleep quality. CONCLUSION: Sleep quality played a mediating role on the relationship between lower urinary tract symptoms and health-related quality of life. Our findings could lead to improvements of diabetes care in nursing and healthcare practices. IMPACT: Understanding the role of sleep quality in the adverse effects of lower urinary tract symptoms on health-related quality of life contributes to the development and delivery of appropriate strategies to promote optimal health-related quality of life. We recommended including assessments of lower urinary tract symptoms, sleep and health-related quality of life in routine diabetes management. Nurses and healthcare professionals should concurrently reduce lower urinary tract symptoms and improve sleep to achieve this population's optimal health-related quality of life. PATIENTS OR PUBLIC CONTRIBUTION: We recruited a sample of older women with type-II diabetes at the endocrinology and metabolism outpatient departments of two hospitals. Study participants provided responses on the study questionnaires. The two hospitals provided needed supports (e.g., height/weight scales, suitable places for interview) during the data collection process.

Far-Infrared Ameliorates Pb-Induced Renal Toxicity via Voltage-Gated Calcium Channel-Mediated Calcium Influx.

Far-infrared (FIR), characterized by its specific electromagnetic wavelengths, has emerged as an adjunctive therapeutic strategy for various diseases, particularly in ameliorating manifestations associated with renal disorders. Although FIR was confirmed to possess antioxidative and anti-inflammatory attributes, the intricate cellular mechanisms through which FIR mitigates lead (Pb)-induced nephrotoxicity remain enigmatic. In this study, we investigated the effects of FIR on Pb-induced renal damage using in vitro and in vivo approaches. NRK52E rat renal cells exposed to Pb were subsequently treated with ceramic-generated FIR within the 9~14 µm range. Inductively coupled plasma mass spectrometry (ICP-MS) enabled quantitative Pb concentration assessment, while proteomic profiling unraveled intricate cellular responses. In vivo investigations used Wistar rats chronically exposed to lead acetate (PbAc) at 6 g/L in their drinking water for 15 weeks, with or without a concurrent FIR intervention. Our findings showed that FIR upregulated the voltage-gated calcium channel, voltage-dependent L type, alpha 1D subunit (CaV1.3), and myristoylated alanine-rich C kinase substrate (MARCKS) (p < 0.05), resulting in increased calcium influx (p < 0.01), the promotion of mitochondrial activity, and heightened ATP production. Furthermore, the FIR intervention effectively suppressed ROS production, concurrently mitigating Pb-induced cellular death. Notably, rats subjected to FIR exhibited significantly reduced blood Pb levels (30 vs. 71 µg/mL; p < 0.01), attenuated Pb-induced glomerulosclerosis, and enhanced Pb excretion compared to the controls. Our findings suggest that FIR has the capacity to counteract Pb-induced nephrotoxicity by modulating calcium influx and optimizing mitochondrial function. Overall, our data support FIR as a novel therapeutic avenue for Pb toxicity in the kidneys.

Influence of basic attributes and attitudes of nurses toward death on nurse turnover: A prospective study.

BACKGROUND: Facing patient death is an unavoidable aspect of work for nurses working in healthcare settings. The attitudes of nurses toward death, however, can exert a negative psychological impact on themselves that can even cause them to quit this occupation. AIM: The objective of this study was to explore the attitudes of nurses toward death, the factors influencing said attitudes, and whether nurses basic attributes and attitudes toward death were associated with their future turnover behavior. METHOD: A prospective study design was adopted. The recruitment period ran from October 2017 to March 2018. A total of 323 nurses completed a basic attributes survey as well as the Death Attitude Profile-Revised questionnaire and were followed until May 30, 2021. The factors influencing turnover were then analyzed using the Cox proportional hazard model. The STROBE checklist was used for reporting in this study. RESULTS: Age was found to be significantly associated with fear of death and death avoidance. Compared with nurses with no religion, nurses who were Buddhists/Taoists were more inclined toward neutral acceptance in their attitude toward death, whereas those who were Christians/Catholics were more inclined toward escape acceptance. Nurses with less than three years of work experience were more likely to resign earlier than those with more than 3 years of work experience. Fear of death and approach acceptance could be used to predict turnover. CONCLUSIONS: Younger nurses were more likely to exhibit fear of death and escape behavior, and those with less work experience or a greater fear of death were more likely to resign. Nurses with religious beliefs could accept patient death more positively, whereas those who faced death with positive approach acceptance displayed reductions in turnover. IMPLICATION FOR NURSING AND HEALTH POLICY: Younger nurses should receive more education regarding death early in their training. Hospitals should also offer more education from a religious aspect in order to reduce turnover.

Mediating effect of job performance between emotional intelligence and turnover intentions among hospital nurses during the COVID-19 pandemic: A path analysis.

Background: Nursing shortages are a persistent and concerning problem for the nursing workforce worldwide. However, the COVID-19 pandemic has brought additional stressors and workloads and has worsened nursing shortages. Aim: To investigate interrelationships among emotional intelligence, job performance, and turnover intentions of nurses during the coronavirus disease 2019 (COVID-19) pandemic, and explore the mediating effect of job performance between emotional intelligence and turnover intentions. Methods: A cross-sectional survey was conducted. In total, 673 nurses working in a medical centre hospital in northern Taiwan were recruited from November 2020 to April 2021. An anonymous questionnaire was used in this survey. Data were collected using a seven-item turnover intention scale, a 16-item emotional intelligence scale, a 24-item job performance scale, and demographic questions. A path analysis was performed. This study was based on STROBE guidelines. Findings: Statistically significant correlations between turnover intentions and emotional intelligence (r = -0.10, p = 0.012), between turnover intentions and job performance (r = -0.13, p = 0.002), and between emotional intelligence and job performance (r = 0.54, p < 0.001) were detected. Model fit indices were adequate. Job performance had a significant indirect effect between emotional intelligence and turnover intentions (ß = -0.16, p = 0.011). Discussion: It was found that job performance was a mediator between emotional intelligence and turnover intentions during the pandemic. The study results support the need to continue to create healthy work environments. Conclusion: These results can assist hospitals in developing specific evidence-based interventions such as showing appreciation and providing acknowledgments to reduce turnover of their nurses during the COVID-19 pandemic.

The relationship between physical activity trajectories and frailty: a 20-year prospective cohort among community-dwelling older people.

BACKGROUND: Studies on examining the relationship between physical activity patterns and frailty are lacking. This study examined physical activity patterns in older people and investigated the relationship between physical activity and frailty as well as identifying the predictors of frailty. METHODS: We used a nationally representative longitudinal database, the Taiwan Longitudinal Study of Aging (TLSA) database, and data for a 20-year period were extracted and analyzed. A total of 5131 participants aged ≥ 60 years in 1996 were included in the current analysis. Information regarding demographic characteristics, frailty, physical activity, comorbidities, oral health, and depressive symptoms was extracted from the TLSA database. Physical activity patterns were examined using group-based trajectory modeling from 1996 to 2015. Potential predictors were examined by performing multivariate logistic regression. RESULTS: Four trajectories of the physical activity pattern were found: consistently physically inactive (33.7%), consistently physically active (21.5%), incline (21.6%), and decline (23.2%). Throughout the period, the trajectories of the four groups significantly differed from each other at year 2015, with the incline and decline groups exhibiting the lowest and highest frailty scores, respectively (p < 0.001). Older age, male, poor oral health, diabetes, chronic kidney disease, and depressive symptoms were identified as risk factors for frailty. CONCLUSION: Physical activity reduces the risk of chronic conditions, which contributes to healthy longevity. This study can guide the development of future research and interventions to manage frailty in older people, particularly in considering previous physical activity trajectories within the life course.

Addressing the ACGME Competency of Communicating with the Public through the Use of TEDx Talks.

OBJECTIVES: Competency-based public communication skills are not systematically taught in most medical curricula, reflecting a gap between medical knowledge and holistic patient care as trainees transition into clinicians. We sought to investigate the efficacy of technology, entertainment, and design (TED) talks in postgraduate year (PGY) training programs. METHODS: The authors organized an official internal TEDx event in which six PGY trainees volunteered as speakers. Two experienced physicians and two administrators also participated as speakers to provide trainees a didactic shadow learning experience. The remaining PGY trainees, along with clerks, physicians, nurses, pharmacists, and administrators, attended the conference. Before the event, speakers undertook individual training sessions and learned the principles of the presentation structure and storytelling mode. At the end of the event, a survey evaluating overall satisfaction in communication skills and professionalism was administered to all of the attendees. RESULTS: Survey participants totaled 104, with a response rate of 97.2%. TEDx talks improved trainees' levels of patient care, communication, and professionalism. Speakers reported the high level of satisfaction with the event (mean 4.96 on a 5-point Likert scale; standard deviation 0.20). Participants agreed that the shadowing experience was useful and that the event encouraged them to pursue interests outside the medical field. CONCLUSIONS: This study highlights that TED is successful in terms of participant satisfaction and training in communication and professionalism. Engaging and training PGY trainees through TED-style events could bridge the gap between acquired knowledge and professional competencies. The authors recommend the implementation of TED-style events in medical training programs.

Medical undergraduates' self-evaluation: before and after curriculum reform.

BACKGROUND: In 2013, Taiwan launched a curriculum reform-the 7-year undergraduate medical education program was shortened to 6 years. This study explored the evaluation results from students regarding the curriculum reform and investigated graduates' perceptions regarding the curriculum organization of the two academic training programs affected by this curricular reform. METHODS: A cross-sectional survey was conducted from May 14 to June 12, 2019. The 315 graduates from both the 7-year and 6-year curriculum programs in the same medical school in Taipei were invited to participate in this study. In total, 197 completed questionnaires were received, representing a response rate of 62.5%. The results of the principal component analysis confirmed the validity of the constructs employed in this self-administered questionnaire. RESULTS: The t-test results yielded two main findings. First, the graduates from the 6-year program had significantly lower scores for preparedness for the upcoming postgraduate-year residency training than did their 7-year program counterparts. Additionally, the male graduates had significantly higher scores in terms of perceptions regarding curriculum organization and preparedness for postgraduate-year residency training than the female graduates. The results of stepwise regression also indicated that the sex difference was significantly correlated with graduates' readiness for their postgraduate-year residency training. CONCLUSION: To avoid sex disparities in career development, a further investigation of female medical students' learning environment and conditions is necessary. In addition to the cross-sectional study of students' perceptions, further repeated measurements of the objective academic or clinical performance of graduates in clinical settings are desirable.

Longitudinal Effects of a Combined Program of Pelvic Floor Muscle Training and Yoga on Genitourinary Symptoms in Asian Women of Older Age: A Randomized Experimental Study.

This parallel-two-group randomized experimental study including a supervised group and an unsupervised group examined the longitudinal effects of pelvic floor muscle training (PFMT) combined with yoga on genitourinary symptoms and the health-related quality of life (HRQOL), and compared practice adherence rates of the two groups. A sample of women experiencing ≥1 genitourinary symptom(s) were recruited and assigned to a supervised group or an unsupervised group. The supervised group attended supervised group practice sessions and performed at-home practice of PFMT and yoga. The unsupervised group performed at-home practice of PFMT and yoga. Information was collected at five time points (n = 91). Generalized estimating equation procedures were used to examine the intervention effects. An independent t-test was conducted to compare the practice adherence rates. Both groups' genitourinary symptoms and HRQOL significantly improved over time. The supervised group displayed greater improvements in genitourinary symptoms and HRQOL and better adherence than did the unsupervised group.

Gender differences in the association between oral health literacy and oral health-related quality of life in older adults.

BACKGROUND: Poor oral health affects quality of life; oral health literacy studies are increasing as it plays an essential role in promoting oral health. However, little is known regarding the gender differences in oral health literacy and oral health-related quality of life (OHRQoL) among older adults. This study aimed to explore the gender differences in oral health literacy and OHRQoL among community-dwelling older adults in Taiwan. METHODS: A cross-sectional study design with convenience sampling was undertaken to recruit participants at two community service centres. Data were collected using a structured survey consisted of the demographic characteristics, instrumental activities of daily living, nutrition assessment, oral health literacy and OHRQoL. The logistic regression was used to examine the gender differences in the relationship between oral health literacy and OHRQoL. RESULTS: A total of 202 participants completed the survey. Of which 56.4% (n = 114) were female. Logistic regression analyses showed that after controlling for age, instrumental activities of daily living, nutrition, education level, and average monthly income, better oral health literacy was associated with better oral health quality of life (p = 0.006) in men. CONCLUSIONS: The relationship between oral health literacy and OHRQoL was only significant for men. No significant relationship between women's oral health literacy and their OHRQoL. However, good OHRQoL is an integral part of overall health, but it is affected by differences in oral health and the accessibility of healthcare services. We suggest that gender-specific oral health literacy education should be offered through community health-education programs.

Relationship between predisposing and facilitating factors: Does it influence the risk of developing peri-operative pressure injuries?

This study examined the relationship between the personal predisposing factors of patients and the severity of pressure injuries (PIs) developed during surgery. This retrospective cohort study collected 439 cases of peri-operative PIs. Using binary logistic regression to identify the variables associated with PI severity, the effects of interactions between associated variables were then tested. The results of this study revealed that among the personal predisposing factors, only higher patient age (P = .001) and higher body mass index (P < .001) posed a greater risk of stage 2 PIs or higher. Among the surgery-related facilitating factors, only patients who were placed in the prone position during surgery and patients who lost ≥1000 mL of blood during surgery were at greater risk of stage 2 PIs or higher, compared, respectively, to those placed in the supine position and those who lost ≤100 mL of blood. Furthermore, the amount of blood lost during surgery moderated the influence of age on PI severity. For elderly patients who are expected to lose a large blood volume during surgery or lose an immeasurable amount of blood due to the use of cardiopulmonary bypass, taking more precautionary measures to prevent PIs is recommended.

Interleukin 8 may predict surgical necrotizing enterocolitis in infants born less than 1500 g.

Necrotizing enterocolitis (NEC) often leads to gastrointestinal emergency resulting high mortality in very low birth weight infants (VLBWIs) requiring surgery. To date, few studies have explored the role of serum cytokines in the development of feeding intolerance (FI) or NEC outcomes in VLBWIs. Infants born weighing <1500 g or of 32 weeks of gestational age were prospectively enrolled from May 2018 to Dec 2019. We measured several cytokines routinely within 72 h of life, even before NEC-like symptoms developed. NEC or FI group comprised 17 (27.4%) infants, and 6 (9.7%) infants had surgical NEC. The gestational age and birth weight were significantly lower in the NEC or FI group with more prematurity-related complications. The surgical NEC group also demonstrated significantly lower gestational age and birth weight along with more infants experiencing refractory hypotension within a 1 week of life, pulmonary hypertension, and patent ductus arteriosus. IL-10 levels were significantly higher in the NEC or FI group, whereas IL-8 levels were significantly higher in the infants with surgical NEC. Our findings indicated to IL-8 can predict surgical NEC while increased IL-10 can predict NEC development in VLBWIs.

Long-term outcomes of metabolic surgery in overweight and obese patients with type 2 diabetes in Asia.

AIM: To assess the outcomes of metabolic surgery in overweight and obese patients in Asia with type 2 diabetes (T2D). MATERIALS AND METHODS: The treatment outcomes of 1999 patients from the Asian Diabetes Surgery Summit database were analysed. The changes in treatment effects across time were assessed with respect to the surgical procedures performed by using generalized estimating equations. RESULTS: The most commonly performed procedure was the single-anastomosis gastric bypass (32.6%). Weight (from 106.2 ± 25.1 to 77.9 ± 18.8 kg), body mass index (BMI; from 38.7 ± 7.9 to 28.5 ± 5.9 kg/m2 ), blood sugar (from 9.3 ± 4.1 to 5.7 ± 1.8 mmol/L) and HbA1c (from 8.4% ± 1.8% to 6.0% ± 1.1%) significantly improved from baseline to 1 year (P < .001) and remained stable at 5 years (weight, 86.3 ± 23.3 kg; BMI, 31.7 ± 7.9 kg/m2 ; blood sugar, 5.8 ± 1.8 mmol/L, and HbA1c, 6.4% ± 1.2%; all P < .001 vs. baseline). Blood pressure and most lipid disorders also improved significantly. Of the treatment procedures, single-anastomosis gastric bypass had the most satisfactory outcomes with statistical significance for most disorders, whereas adjustable gastric banding displayed the least satisfactory outcomes. CONCLUSIONS: Metabolic surgery remarkably improved body weight, T2D and other metabolic disorders in Asian patients. However, the efficacy of individual procedures varied substantially.

Influence of Shared Decision Making on Decisional Conflict and Regret in Postpartum Mother-Infant Care: A Randomized Controlled Trial.

OBJECTIVES: Although postpartum rooming-in is encouraged by the World Health Organization, independent separated nursery care is still widely adopted in Eastern countries. Our aim is to evaluate the effect of shared decision making (SDM) assisted by patient decision aids on subjective decisional conflict and regret among women who are required to make choices regarding postpartum infant care. METHODS: A total of 196 pregnant women who came for routine checkups 1 month before delivery were randomly assigned to the SDM group or the classic group. Before the mothers were discharged after delivery, their decision-making difficulties were evaluated. The primary outcome was the decisional conflict, which was assessed using the SURE (Sure of myself; Understand information; Risk-benefit ratio; Encouragement) scale. The secondary outcome was the decisional regret, which was measured using the Decision Regret scale. RESULTS: Compared with the classic group, SDM group had surer feelings about the choice (P＜.001), felt more confident about knowing the benefits and risks of each option (P＜.001), had a clearer understanding of the benefits and risks (P＜.001), and felt sufficiently supported with enough advice to make a suitable choice (P＜.001). No significant difference was noted in the Decision Regret scores between groups. The choice of 24-hour rooming-in, 12-hour rooming-in, and separated nursery care was not significantly different between groups. CONCLUSIONS: SDM reduced the decisional conflict and uncertainty of the mothers. Available choices of postpartum mother-infant care should be provided to mothers through SDM that includes individual values, health goals, and clear knowledge and transparency.

Electrical Cardiometry and Cardiac Biomarkers in 24-h and 48-h Ultramarathoners.

Our study aimed to (i) utilize novel electrical cardiometry and observe acute changes in cardiac biomarkers among 24-h and 48-h ultra-marathoners, and (ii) examine whether alterations in cardiac responses were associated with the average running speed of these participants. Twenty-four 24-h and sixteen 48-h ultra-marathoners were recruited. Electrical cardiometry in the 2 groups showed significant post-race drops in systolic pressure (24-h: p=0.001; 48-h: p=0.016) and rapid increases in heart rate (24-h, p=0.004; 48-h, p=0.001). Cardiac output increased in 48-h runners (p=0.012) and stroke volume decreased in 24-h runners (p=0.009) at post-test. Six of 20 (30%) 24-h and 4 of 16 (25%) 48-h runners had high-sensitivity troponin T values above the reference interval after the races. N-terminal proB-type natriuretic peptide levels showed a 15-fold increase in 24-h runners and a 10-fold increase in 48-h runners at post-race. There was a positive correlation between delta N-terminal proB-type natriuretic peptide and running mileage (rs=0.629, p=0.003) in 24-h ultra-marathoners. In conclusion, stroke volume and cardiac output showed inconsistent changes between the 2 groups. Average running speed has a significant effect on post-exercise elevation in cardiac biomarkers.

Visual hallucinations in 246-km mountain ultra-marathoners: An observational study.

Ultra-marathons are typically held over harsh terrains such as mountains, deserts, or other wilderness, and place severe demands on the physical and psychological capabilities of participants. Adventure-race competitors commonly report hallucinations. The goal of this study was to gain insight into visual hallucinations (VHs) during a mountain ultra-marathon. Thirty-one Taiwanese runners who participated in the 2018 Run Across Taiwan Ultra-Marathon, which spans 246 km with an altitude difference of 3266 m and an overall cut-off time of 44 h, volunteered for this study. Self-reported questionnaires on sleep duration, hallucinatory experiences, clinical symptoms of cold- and heat-related illnesses, and the 2018 Lake Louise Acute Mountain Sickness (AMS) Score were recorded prerace, during the summit, immediately postrace, and 3-days postrace. Hematological samples were collected 1 week before, immediately after, and 3 days after the race. Eight ultra-marathoners (six males and two females; seven finishers and one withdrawer) were recruited. Three out of eight (37.5%) subjects (two males and one female) reported experiencing VHs during the last 60 km. Three out of five (60%) lower-ranked subjects experienced VHs. All eight runners slept for <30 min during the race. None of the runners presented with headache either during or after the race to meet the criteria for AMS. None of the runners suffered an abnormal thermoregulatory response or a hypoglycemic episode throughout the ultra-marathon. The changes in blood osmolality immediately postrace were subclinical, despite being statistically significant. Among the three runners with VHs, none presented with severe dehydration or dysnatremia immediately postrace. High-altitude exposure, hyper/hypothermia, dehydration, dysnatermia, or hypoglycemia did not seem to contribute to hallucination onset in our subjects during the event. VHs of ultra-marathoners may be associated with excessive physical exertion and sleep deprivation.
