The effect of progressive exercise prescription for group exercise guidance for Taiwan seniors and Integrated Care for old People: Post-event movement observation

Purpose

This study is aimed at the seniors of the "2022 Taiwan Senior Citizens Fitness Club Subsidy Plan" with a sample.

Method

The doctor will diagnose and confirm whether the physical condition suits participation. Then, the professional sports instructor will design and arrange a progressive fitness enhancement group course suitable for the Senior person's physical fitness, conducted four times a week, every 2 h, for three months of group course training. Afterward, four group course instructors analyzed the motor ability of the three periods through a video, divided into 21 evaluation indicators. The data collection will be from January to May 2023. In addition, the Integrated Care for Old People (ICOPE) was used to assess the situation.

Result

The results showed that all indexes were significantly better than those in week one at week 6. All indexes at week 12 were significantly better than those in week one and week 6 (p < .001), and the benefit of all indicators was the largest (Cohen's d: 2.79-5.11), the reliability of the scores of each index ICC (0.73-0.94).

Conclusion

Progressive and multifaceted guidance on how to safely and effectively enhance the physical activity of senior citizens may be the most suitable method. Through progressive energy enhancement, the participants' physical activity and cognitive function can be improved, especially the overall rhythm of the music, which can be combined with high and low impact, dynamic and static balance control, agility, flexibility, and extensibility to achieve the benefits of health promotion.

Factors Associated With Diabetes Self-Care Performance in Indonesians With Type 2 Diabetes: A Cross-Sectional Study

BACKGROUND

In Indonesia, the number of Type 2 diabetes cases is increasing rapidly, making it the third leading cause of death and among the leading noncommunicable disease healthcare expenditures in the country. Thus, there is a critical need for Indonesians with Type 2 diabetes to perform better self-care to optimize their health and prevent the onset of comorbidities.

PURPOSE

This study was designed to investigate the influence of knowledge, depression, and perceived barriers on Type 2 diabetes self-care performance in Indonesia.

METHODS

A cross-sectional study was conducted on 185 patients with Type 2 diabetes, with demographic, diabetes history, obesity status, diabetes knowledge, depression, perceived barriers, and self-care performance data collected. The Indonesian version of the Revised Diabetes Knowledge Test, Depression Anxiety Stress Scale, Perceived Barrier Questionnaire and Self-Care Inventory-Revised were used. Descriptive, bivariate, and multiple linear regression analyses were performed.

RESULTS

Study participants were found to have moderate diabetes self-care performance scores. Annual eye checks, blood glucose self-monitoring, healthy diet selection, and regular exercise were the least common self-management techniques performed and were consistent with the perceived difficulties of the participants. Being illiterate or having an elementary school education (β = 4.59, p = .002), having a junior or senior high school education (β = 3.01, p = .006), having moderate depression (β = -0.92, p = .04), diabetes knowledge (β = 0.09, p = .006), and perceived barriers (β = 0.31, p < .001) were found to explain 40% of the variance in self-care performance. Educational level, depression, and perceived barriers were the strongest factors that impacted Type 2 diabetes self-care performance in this study.

CONCLUSIONS/IMPLICATIONS FOR PRACTICE

Nurses should not only provide diabetes education but also identify barriers to diabetes self-care early, screen for the signs and symptoms of depression, and target patients with lower levels of education.

High myopia at high altitudes

Background: Optic nerve sheath diameter (ONSD) increases significantly at high altitudes, and is associated with the presence and severity of acute mountain sickness (AMS). Exposure to hypobaria, hypoxia, and coldness when hiking also impacts intraocular pressure (IOP). To date, little is known about ocular physiological responses in trekkers with myopia at high altitudes. This study aimed to determine changes in the ONSD and IOP between participants with and without high myopia (HM) during hiking and to test whether these changes could predict symptoms of AMS. Methods: Nine participants with HM and 18 without HM participated in a 3-day trek of Xue Mountain. The ONSD, IOP, and questionnaires were examined before and during the trek of Xue Mountain. Results: The ONSD values increased significantly in both HM (p = 0.005) and non-HM trekkers (p = 0.018) at an altitude of 1,700 m. In the HM group, IOP levels were greater than those in the non-HM group (p = 0.034) on the first day of trekking (altitude: 3,150 m). No statistically significant difference was observed between the two groups for the values of ONSD. Fractional changes in ONSD at an altitude of 1,700 m were related to the development of AMS (r pb = 0.448, p = 0.019) and the presence of headache symptoms (r pb = 0.542, p = 0.004). The area under the ROC curve for the diagnostic performance of ONSD fractional changes at an altitude of 1,700 m was 0.859 for predicting the development of AMS and 0.803 for predicting the presence of headache symptoms. Conclusion: Analysis of changes in ONSD at moderate altitude could predict AMS symptoms before an ascent to high altitude. Myopia may impact physiological accommodation at high altitudes, and HM trekkers potentially demonstrate suboptimal regulation of aqueous humor in such environments.

Incidence of Postoperative Delirium in Cancer Patients After Head and Neck Surgery: A Proportional Meta-analysis

OBJECTIVE

To summarize the incidence of postoperative delirium among cancer patients undergoing head and neck surgery and determine the differential incidence rates among patients undergoing different types of head and neck surgeries.

DATA SOURCES

The databases of PubMed, Cochrane Library, Web of Science, EMBASE, and CINAHL were searched from inception till February 2023. Keywords based on the condition (delirium), context (postoperative), and population (head and neck cancer) were used as search terms.

REVIEW METHODS

The PRISMA and MOOSE reporting guidelines were followed. The Joanna Briggs Institute critical appraisal checklists for cohort studies, case-control studies, and randomized controlled trials were used to evaluate the methodological quality. Data were pooled using a random-effects model, and the incidence with 95% confidence intervals was evaluated using the exact binomial method and Freeman-Tukey double arcsine transformation of proportions. I2 was used to indicate heterogeneity. Predefined subgroup analysis and Meta-regression, was performed to identify the factors affecting heterogeneity.

RESULTS

The summary incidence of postoperative delirium was 18.95% [95% confidence interval, 14.36%-24.00%] with between-study heterogeneity (I2  = 95.46%). The incidence of postoperative delirium in patients who underwent free flap reconstruction was 22.13%, which was higher than those of other types of surgeries. Meta-regression revealed that conducted in sample size (P = .007) of the included studies was the factors affecting heterogeneity.

CONCLUSIONS

The evidence on postoperative delirium incidence provided by the current Meta-analysis enables effective treatment planning.

Association of Neonatal Antibiotic Exposure with Long-Term Growth Trajectory Faltering in Preterm-Birth Children

INTRODUCTION

Preterm neonates often receive a variety of duration of antibiotic exposure during admission. The aim of the study was to evaluate whether neonatal antibiotic exposure is relevant with longitudinal growth problems in preterm-birth children.

METHODS

This prospective study enrolled 481 infants who were born <32 weeks of gestation, discharged, and longitudinally followed from corrected age (CA) 6-60 months. After excluding 153 infants with blood culture-confirmed bacteremia, necrotizing enterocolitis, severe cerebral palsy, intestinal ostomy, and congenital anomaly, 328 infants were included for analysis. Covariates included perinatal demographics, neonatal morbidities, extrauterine growth restriction, and antibiotic exposure accumulated by term equivalent age. The primary outcome was the anthropometric trajectories in z-score of bodyweight (zBW), body height (zBH), and body mass index (zBMI) from CA 6-60 months.

RESULTS

Antibiotic exposure duration was significantly negatively associated with zBW and zBH at CA 6, 12, and 60 months, and zBMI at CA 60 months. Multivariate generalized estimating equation analyses showed antibiotic exposure duration had significantly faltering z-score increment from CA 6 to 60 months in zBW and zBH (adjusted mean [95% CI]; ΔzBW: -0.021 [-0.041 to -0.001], p = 0.042; ΔzBH: -0.019 [-0.035 to -0.002], p = 0.027) after adjustment. Children with neonatal antibiotic exposure duration >15 days were significantly lower in the mean anthropometric zBW, zBH, and zBMI at CA 6, 12, 24, and 60 months compared with children with neonatal antibiotic exposure ≤15 days (all p < 0.01).

CONCLUSIONS

Growth increments were negatively associated with antibiotic exposure duration in preterm neonates implicating that antibiotic stewardship and growth follow-up for preterm neonates are thus warranted.

Antidepressant sertraline increases thioflavin-S and Congo red deposition in APPswe/PSEN1dE9 transgenic mice

Introduction: Depression is strongly associated with Alzheimer's disease (AD). Antidepressants are commonly used in patients before and after their diagnosis of AD. To date, the relationship between antidepressants and AD remains unclear. Methods: In our study, we administered sertraline or paroxetine to wild type (WT) and APPswe/PSEN1dE9 (APP/PSEN1) transgenic mouse models for up to 12 months. We quantified the drug concentrations using LC-MS/MS analysis and measured serum serotonin level using an ELISA assay. Additionally, we evaluated the amyloid burdens through thioflavin-S and Congo red stainings, and recognition memory using the novel object recognition test. Results: Our findings revealed that mice treated with paroxetine exhibited a significantly higher level of weight gain compared to the control group and increased mortality in APP/PSEN1 mice. After 12 months of antidepressant treatment, the sertraline level was measured at 289.8 ng/g for cerebellum, while the paroxetine level was 792.9 ng/g for cerebellum. Sertraline significantly increased thioflavin-S and Congo red depositions, along with gliosis, in both isocortex and hippocampus of APP/PSEN1 mice compared to the control group. Both antidepressants also led to a decreased recognition index in APP/PSEN1 mice. Conclusion: These findings suggest a potential role of sertraline in AD pathogenesis, emphasizing the need to reassess the use of these antidepressants in patients with AD.

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.

The Efficacy of Health Promotion Program Among Parents Who Had Children With Attention-Deficit/Hyperactivity-Disorder

OBJECTIVES

To explore the effect of health promotion program (HPP) on stress, quality of life, health-promoting lifestyles, and children's attention-deficit/hyperactivity disorder (ADHD) symptoms in parents of children with ADHD.

METHODS

Sixty parents of children with ADHD were equally randomized into the intervention (health promotion program) and control (usual care) groups. Outcomes included parents' stress, quality of life, health-promoting lifestyles, and children's ADHD symptoms before, immediately after, and 1, 3, and 6 months after the intervention. The GEE was used to evaluate the effectiveness.

RESULTS

The intervention group reported significant improvement in the children's hyperactivity/impulse and opposition at the 6- and 3-month, respectively. Parental overall stress significantly improved at 3 and 6 months. Parents' quality of life had significant effects at the immediate, 3-month, and 6-month. Self-actualization behavior for health-promoting lifestyles had significant effects at the immediate follow-up.

CONCLUSION

HPP can promote the mental well-being of parents of children with ADHD.

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.

Tn as a potential predictor for regional lymph node metastasis in T1 colorectal cancer

BACKGROUND

Approximately 10 percent of T1 colorectal cancer (CRC) has lymph node metastasis. In this study, we aimed to determine possible predictors for nodal involvement in order to aid selection of appropriate patients for organ-preserving strategies.

METHODS

We retrospectively reviewed CRC patients underwent radical surgery from January 2009 to December 2016, with final pathology report disclosed as T1 lesion. The paraffin-embedded samples were achieved for glycosylated proteins expression analysis by immunohistochemistry.

RESULTS

Totally, 111 CRC patients with T1 lesion were enrolled in this study. Of these patients, seventeen patients had nodal metastases, with the lymph node positive rate of 15.3%. Semiquantitative analysis of immunohistochemical results indicated that mean value of Tn protein expression in T1 CRC specimens was significantly different between patients with and without lymph node metastasis (63.6 vs. 27.4; p = 0.018).

CONCLUSIONS

Our data shown that Tn expression may be applied as a molecular predictor for regional lymph node metastasis in T1 CRC. Moreover, the organ-preserving strategy could be improved by proper classification of patients. The mechanism involved in expression of Tn glycosylation protein and CRC metastasis need further investigation.

Artificial intelligence based system for predicting permanent stoma after sphincter saving operations

Although the goal of rectal cancer treatment is to restore gastrointestinal continuity, some patients with rectal cancer develop a permanent stoma (PS) after sphincter-saving operations. Although many studies have identified the risk factors and causes of PS, few have precisely predicted the probability of PS formation before surgery. To validate whether an artificial intelligence model can accurately predict PS formation in patients with rectal cancer after sphincter-saving operations. Patients with rectal cancer who underwent a sphincter-saving operation at Taipei Medical University Hospital between January 1, 2012, and December 31, 2021, were retrospectively included in this study. A machine learning technique was used to predict whether a PS would form after a sphincter-saving operation. We included 19 routinely available preoperative variables in the artificial intelligence analysis. To evaluate the efficiency of the model, 6 performance metrics were utilized: accuracy, sensitivity, specificity, positive predictive value, negative predictive value, and area under the receiving operating characteristic curve. In our classification pipeline, the data were randomly divided into a training set (80% of the data) and a validation set (20% of the data). The artificial intelligence models were trained using the training dataset, and their performance was evaluated using the validation dataset. Synthetic minority oversampling was used to solve the data imbalance. A total of 428 patients were included, and the PS rate was 13.6% (58/428) in the training set. The logistic regression (LR), Gaussian Naïve Bayes (GNB), Extreme Gradient Boosting (XGB), Gradient Boosting (GB), random forest, decision tree and light gradient boosting machine (LightGBM) algorithms were employed. The accuracies of the logistic regression (LR), Gaussian Naïve Bayes (GNB), Extreme Gradient Boosting (XGB), Gradient Boosting (GB), random forest (RF), decision tree (DT) and light gradient boosting machine (LightGBM) models were 70%, 76%, 89%, 93%, 95%, 79% and 93%, respectively. The area under the receiving operating characteristic curve values were 0.79 for the LR model, 0.84 for the GNB, 0.95 for the XGB, 0.95 for the GB, 0.99 for the RF model, 0.79 for the DT model and 0.98 for the LightGBM model. The key predictors that were identified were the distance of the lesion from the anal verge, clinical N stage, age, sex, American Society of Anesthesiologists score, and preoperative albumin and carcinoembryonic antigen levels. Integration of artificial intelligence with available preoperative data can potentially predict stoma outcomes after sphincter-saving operations. Our model exhibited excellent predictive ability and can improve the process of obtaining informed consent.

[Hereditary pulmonary hypertension family with BMPR2 gene variation: a case report and literature review]

Objective: To describe the clinical characteristics, diagnosis, genetic features and treatment of hereditary pulmonary hypertension complicated with suspected hereditary hemorrhagic telangiectasia (HHT). Methods: Firstly, we summarized and analyzed the clinical data of two cases of suspected HHT admitted to the Department of Pulmonary and Critical Care Medicine, the Second Xiangya Hospital, Central South University. Secondly, the genes of peripheral blood of patients and their families were completely sequenced and sanger sequencing was performed to verify the variation sites, and then the mRNA deletion caused by the variation was further verified. Thirdly, "HHT" "FPAH" and "BMPR2 gene variation" were used as keywords,and the related literatures of Wanfang database and PubMed database from January 2000 to November 2021 were searched and reviewed. Results: We found two patients in a family from Yiyang, Hunan province, who had symptoms of hemoptysis or pulmonary hypertension without epistaxis or other clinical features of HHT. However, both patients had pulmonary vascular abnormalities and pulmonary hypertension in their lungs. We found that BMPR2 gene variation (NM_001204.7:c.1128+1G>T) was positive and ENG, ACVRL1 and SMAD4 genes were negative. Family analysis and Sanger verification were carried out on 16 individuals in 4 generations of the family (7 of whom were found to carry the mutant gene), and then transcriptional level mRNA sequencing further confirmed that the variation resulted in the deletion of exon 8 and exon 9, and amino acid sequence estimation revealed that the amino acids of the protein from 323 to 425 were deleted. We thought that the incomplete translation of BMPR2 gene could lead to BMPRⅡ dysfunction. Therefore, it was diagnosed as hereditary pulmonary hypertension with suspected HHT. Both patients were suggested to reduce the pulmonary artery pressure, and at the same time, the whole-body imaging examination should be performed to screen other arteriovenous malformations, and the annual cardiac color Doppler ultrasound should be reviewed to evaluate the changes of pulmonary artery pressure. Conclusions: Hereditary pulmonary hypertension (HPAH) is a group of diseases with increasing pulmonary vascular resistance caused by genetic factors, including familial PAH and simple PAH. Variation in the BMPR2 gene is an important pathogenic factor of HPAH. Therefore, we should pay attention to the inquiry of family history when we clinically encounter young patients with pulmonary hypertension. If the cause is unknown, genetic testing is recommended. HHT is a rare autosomal dominant genetic disease. The possibility of this disease should be considered in clinical manifestations such as familial pulmonary vascular abnormality, pulmonary hypertension and recurrent epistaxis. There is no effective specific treatment for HPAH and HHT, which are treated symptomatically (including blood pressure reduction and hemostasis, etc.). It is suggested for these patients that pulmonary artery pressure should be dynamically monitored and have genetic counseling before giving birth.

Acupressure Improves Cognition and Quality of Life Among Older Adults with Cognitive Disorders in Long-Term Care Settings: A Clustered Randomized Controlled Trial

OBJECTIVE

To examine the effectiveness of acupressure on cognition and quality of life (QoL) among older adults with cognitive disorders residing in long-term care (LTC) settings.

DESIGN

A clustered, randomized, assessor-blinded, controlled trial with a repeated measures design.

SETTING AND PARTICIPANTS

Participants were recruited from residential care facilities in Taiwan from August 2020 to February 2021. Ninety-two older residents in 18 facilities were randomized to either the intervention arm (9 facilities, n = 46) or the control arm (9 facilities, n = 46).

METHODS

Acupressure was performed at Baihui (GV20), Sishencong (EX-HN1), Shenting (GV24), Fengchi (GB20), Shuigou (GV26), Neiguan (PC6), Shenmen (HT7), and Zusanli (ST36). The duration for pressing each acupoint was 3 minutes. The acupressure force was maintained at 3 kg. Acupressure was performed once a day 5 times a week for 12 weeks. The primary outcome measure was the Cognitive Abilities Screening Instrument (CASI). Secondary outcomes included the digit span backward test, the Wisconsin Card Sorting Test (perseverative responses, perseverative errors, and categories completed), semantic fluency tests of categories of animals, fruits, and vegetables, and the Quality of Life-Alzheimer's Disease (QoL-AD). Data were collected at preintervention and postintervention. Three-level mixed effects models were performed. This study complied with the CONSORT checklist.

RESULTS

After adjusting for covariates, there was a significant increase in CASI scores, the digit span backward test, perseverative responses, perseverative errors, categories completed, semantic fluency tests of categories, and QoL-AD scores in the intervention versus control arm at 3 months.

CONCLUSIONS AND IMPLICATIONS

This study provides support for the use of acupressure to improve cognition and QoL during care among older residents with cognitive disorders in LTC settings. Acupressure can be integrated into aged care practice to improve cognition and QoL of older residents with cognitive disorders in LTC settings.

Effects of Online Video Sport Spectatorship on the Subjective Well-Being of College Students: The Moderating Effect of Sport Involvement

Individuals' engagement in sports and sport-related entertainment is reported to improve their subjective well-being (SWB). We investigated whether online video sport spectatorship (OVSS) enhances the SWB of college students and whether sport involvement moderates the correlation between OVSS and SWB. For this, a pretest-posttest experimental design with a 3-week-long intervention (OVSS) was adopted. Two groups, intervention and control, were formed. The findings revealed that OVSS improved SWB (p = 0.017). Furthermore, sport involvement moderated the correlation between OVSS and SWB (p = 0.024). Specifically, participants with high levels of sport involvement in the intervention group exhibited better SWB (M = 5.51) than did the corresponding controls (M = 4.69). By contrast, among participants with low levels of sport involvement, only the intervention group showed improved SWB; however, it remained unchanged in the control group. The present study enriches the relevant literature and provides empirical evidence for the psychological benefits conferred by OVSS. Our findings may serve as a reference for designing interventions aimed at improving individuals' overall quality of life.

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.

[Scimitar syndrome with pulmonary sequestration containing carcinoma: a case report]

We reported the manifestations, auxiliary examination, and treatment courses of a case of scimitar syndrome with pulmonary sequestration containing carcinoma. The clinical characteristics of scimitar syndrome with pulmonary sequestration, pulmonary sequestration containing carcinoma were summarized based on the data of this case and the related literatures before January 2022. Scimitar syndrome can coexist with ipsilateral pulmonary sequestration. Because sequestered lung tissue has a risk of malignant transformation, a cancer screening test is useful for early diagnosis and timely treatment.

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.

Psychometric properties and cross-cultural adaptation of the Indonesian version of the Brief COPE in a sample of advanced cancer patients

The Brief COPE Inventory has been proven as acceptable psychometric properties to examine coping strategies among cancer patients. However, most psychometric testing studies have been carried out in Western countries, raising concerns about the properties' relevance and applicability in other cultural contexts. This study aimed to present psychometric properties of the Brief COPE in a sample of patients with advanced cancer in Indonesia. Specifically, we intended to examine the factorial structure and the measure's validity and reliability. This study included 440 patients from the original study who completed the Indonesian version of Brief COPE. We used exploratory factor analysis and confirmatory factor analysis to assess factor structure and evaluate the structural model fit, respectively. Reliability was demonstrated by internal consistency represented by Cronbach's alpha coefficient. The factor analysis identified a 21-items scale with 5-factors (avoidance, religion and acceptance, social support coping, problem solving and distraction). Confirmatory factor analysis demonstrated a good model fit. For the whole scale and its subscales Cronbach's alpha coefficients were acceptable signifying good reliability. Convergent, divergent validity and contrast group comparison were evidenced by significant correlations among subscales and the other instruments used. This study shows that the Indonesian version of Brief COPE is a reliable and valid instrument to measure coping in advanced cancer patients and is ready for use amongst this population in the Indonesian cultural context.

Urinary Incontinence and Sleep Quality in Older Women with Type 2 Diabetes: A Cross-Sectional Study

BACKGROUND

Urinary incontinence (UI) and poor sleep negatively affect health-related quality of life (HRQoL). This study explored the UI-related factors and the relationships between UI, sleep quality, and HRQoL.

METHODS

This cross-sectional study collected data from 237 women with type 2 diabetes. Multivariate logistic regression was conducted to identify the factors associated with UI. One-way analysis of variance was used to compare the mean sleep quality and HRQoL scores of women without UI and those who experienced UI of varying severities. Correlation coefficients were estimated, and multivariate linear regression was conducted to examine the relationships between UI severity, sleep quality, and HRQoL.

RESULTS

Of the 237 women, 115 (48.52%) experienced UI and 139 (58.65%) were poor sleepers. The three factors associated with UI were advanced age, a higher body mass index, and a history of vaginal delivery. Significant associations between UI severity and sleep quality and between sleep quality and HRQoL were revealed. UI severity and night-time voiding frequency were both associated with sleep quality.

CONCLUSIONS

One factor associated with UI (body mass index) is modifiable. UI severity is associated with sleep quality as the possible influence of night-time voiding frequency on sleep quality has been considered.

The changes of electroencephalography in mountaineers on Mount Jade, Taiwan: An observational study

BACKGROUND

The diagnosis of acute mountain sickness, which lacks a reliable and objective diagnostic tool, still depends on the clinical symptoms and signs and remains a major threat and unpredictable disease affecting millions of mountaineers.

OBJECTIVES

To record electroencephalography signals with small, convenient, wireless equipment and to test whether electroencephalography parameters, which are more sensitive and reliable markers, could predict the symptoms of acute mountain sickness.

METHODS

Twenty-five participants were enrolled and separated into two groups to climb Mount Jade in Taiwan. We collected electrocardiography signals and arterial oxygen saturation data at ground, moderate (2,400 m), and high altitude (3,400 m). A spectral analysis of the electrocardiography was performed to assess the study subjects' electroencephalography activity at different frequencies (α, β, θ, δ) and the mean power frequency of electrocardiography. The clinical symptoms and Lake Louise Acute Mountain Sickness scores of the subjects were recorded for comparison.

RESULTS

A significant change in the δ power of electroencephalography was recorded in subjects ascending from the ground to a high altitude of 3,400 m in a 4-day itinerary. In addition, between the two groups of subjects with and without acute mountain sickness (Lake Louise Acute Mountain Sickness scores < 3 and ≥ 3), the δ power of electroencephalography at the fronto-parietal 1 and parietal 3 electrodes at moderate altitude as well as the changes of δ power and mean power frequency of electrocardiography over parietal 4 at high altitude showed a significant difference. At moderate altitude, the increasing δ power of electroencephalography at the parietal 4 electrode was related to the headache symptom of acute mountain sickness before ascending to high altitude.

CONCLUSION

At moderate altitude, the δ power increase of electroencephalography at the P4 electrode could be a predictor of acute mountain sickness symptoms before ascending to high altitude. Thus, electroencephalography had the potential to identify the risk of acute mountain sickness.

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.

Television watching, reading, cognition, depression and life satisfaction among middle-aged and older populations: A group-based trajectory modelling analysis of national data

This retrospective cohort study aimed to identify heterogeneous cognition, depression, and life satisfaction trajectory groups, and to examine the independent contributions of watching television and reading to these trajectories among middle-aged and older adults. A sample was taken from the Taiwan Longitudinal Study on Aging (TLSA) with measures of cognition, depression, life satisfaction, watching television, and reading during 12 years of follow-up (N = 4440). Group-based trajectory models and multinomial logistic regressions were used. The findings showed that the cohort was separated into three global cognition groups of low-cognition (n = 376), declining-cognition (n = 805), and maintained-cognition (n = 2718); three episodic memory groups of high-declining (n = 540), middle-stable (n = 2066), and improving groups (n = 1293); three depression groups of low-to-low (n = 2571), median-to-high (n = 960), and high-to-high groups (n = 368); and three life satisfaction groups of low- (n = 1133), middle- (n = 977), and high-level groups (n = 1789). Also, the findings demonstrated that after adjusting for covariates, those who did not watch television or read at the baseline had independently significantly increased odds of having lower global cognitive function, higher depression, and lower life satisfaction over time versus those who watched television or read almost every day. Based on the findings obtained, group-based trajectories of cognition, depression, and life satisfaction scores identified distinct subgroups among TLSA participants. Moreover, the findings suggest that healthcare providers need to develop more targeted population interventions to ensure successful aging. Healthcare providers can encourage older adults, particularly new retirees, to participate in leisure activities (i.e., watching television and reading) to reduce prevalence rates of cognitive impairment and depression.

Clinical assessment for non-reversal stoma and stoma re-creation after reversal surgery for rectal cancer patients after sphincter-saving operation

BACKGROUND

This study aimed to identify the risk factors for permanent stoma (PS) in patients who underwent sphincter-saving operations for rectal cancer.

METHODS

We retrospectively reviewed 597 consecutive patients with rectal cancer from January 2012 to December 2020 at Taipei Medical University Hospital. Univariate and multivariable analyses were used to analyze risk factors for PS.

RESULTS

After a mean follow-up of 47.3 months (range 7-114 months), 59 patients (15.1%) were alive with a PS, including 46 patients who did not undergo reversal surgery and 13 patients who underwent stoma re-creation after reversal surgery. The mean period between primary surgery and stoma reversal was 6.0 months. Multivariate analysis revealed that the risk factors for PS were local recurrence [odd ratio (OR), 25.58; 95% confidence interval (CI), 4.428-147.761; p < 0.001], perirectal abscess [OR, 154.34; 95% CI, 15.806 - >999; p < 0.001], anastomosis site stenosis [OR, 187.081; 95% CI, 22.193 - >999; p < 0.001], perineural invasion [OR, 4.782; 95% CI, 1.22-18.736; p = 0.025], and operation time (min) [OR, 1.008; 95% CI, 1.002-1.014; p = 0.01].

CONCLUSIONS

Local recurrence, perirectal abscess, anastomosis site stenosis, perineural invasion, and operation time were independent risk factors for PS. Therefore, before a patient undergoes surgery for rectal cancer, surgeons should consider the possibility of the need for a PS, and patients should be informed before the operation that closure of the temporary stoma may not always be possible.

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 (β = −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.

Nomogram to predict permanent stoma in rectal cancer patients after sphincter-saving surgery

BACKGROUND

Approximately 20 percent of patients with a tumour localized in the low rectum still encounter the possibility of requiring permanent stoma (PS), which can cause drastic changes in lifestyle and physical perceptions.

AIM

To determine the risk factors for PS and to develop a prediction model to predict the probability of PS in rectal cancer patients after sphincter-saving surgery.

METHODS

A retrospective cohort of 421 rectal cancer patients who underwent radical surgery at Taipei Medical University Hospital between January 2012 and December 2020 was included in this study. Univariate and multivariate analyses were performed to identify the independent risk factors for PS. A nomogram was developed according to the independent risk factors obtained in the multivariate analysis. The performance of the nomogram was assessed using a receiver operating characteristic curve and a calibration curve.

RESULTS

The PS rate after sphincter-saving surgery was 15.1% (59/391) in our study after a median follow-up of 47.3 mo (range 7–114 mo). Multivariate logistic regression analysis demonstrated that local recurrence, perirectal abscess, anastomosis site stenosis, perineural invasion, tumor size and operative time were independent risk factors for PS. These identified risk factors were incorporated into the nomogram, and the concordance index of this model was 0.903 (95%CI: 0.851-0.955). According to the calibration curves, the nomogram represents a perfect prediction model.

CONCLUSION

Several risk factors for PS after sphincter-saving surgery were identified. Our nomogram exhibited perfect predictive ability and will improve a physician’s ability to communicate the benefits and risks of various treatment options in shared decision making.

Determinants of coronavirus disease 2019 infection by artificial intelligence technology: A study of 28 countries

Objectives

The coronavirus disease 2019 pandemic has affected countries around the world since 2020, and an increasing number of people are being infected. The purpose of this research was to use big data and artificial intelligence technology to find key factors associated with the coronavirus disease 2019 infection. The results can be used as a reference for disease prevention in practice.

Methods

This study obtained data from the "Imperial College London YouGov Covid-19 Behaviour Tracker Open Data Hub", covering a total of 291,780 questionnaire results from 28 countries (April 1~August 31, 2020). Data included basic characteristics, lifestyle habits, disease history, and symptoms of each subject. Four types of machine learning classification models were used, including logistic regression, random forest, support vector machine, and artificial neural network, to build prediction modules. The performance of each module is presented as the area under the receiver operating characteristics curve. Then, this study further processed important factors selected by each module to obtain an overall ranking of determinants.

Results

This study found that the area under the receiver operating characteristics curve of the prediction modules established by the four machine learning methods were all >0.95, and the RF had the highest performance (area under the receiver operating characteristics curve is 0.988). Top ten factors associated with the coronavirus disease 2019 infection were identified in order of importance: whether the family had been tested, having no symptoms, loss of smell, loss of taste, a history of epilepsy, acquired immune deficiency syndrome, cystic fibrosis, sleeping alone, country, and the number of times leaving home in a day.

Conclusions

This study used big data from 28 countries and artificial intelligence methods to determine the predictors of the coronavirus disease 2019 infection. The findings provide important insights for the coronavirus disease 2019 infection prevention strategies.

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.

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.

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.

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.

Robustness of autoencoders for establishing psychometric properties based on small sample sizes: results from a Monte Carlo simulation study and a sports fan curiosity study

BACKGROUND

The principal component analysis (PCA) is known as a multivariate statistical model for reducing dimensions into a representation of principal components. Thus, the PCA is commonly adopted for establishing psychometric properties, i.e., the construct validity. Autoencoder is a neural network model, which has also been shown to perform well in dimensionality reduction. Although there are several ways the PCA and autoencoders could be compared for their differences, most of the recent literature focused on differences in image reconstruction, which are often sufficient for training data. In the current study, we looked at details of each autoencoder classifier and how they may provide neural network superiority that can better generalize non-normally distributed small datasets.

METHODOLOGY

A Monte Carlo simulation was conducted, varying the levels of non-normality, sample sizes, and levels of communality. The performances of autoencoders and a PCA were compared using the mean square error, mean absolute value, and Euclidian distance. The feasibility of autoencoders with small sample sizes was examined.

CONCLUSIONS

With extreme flexibility in decoding representation using linear and non-linear mapping, this study demonstrated that the autoencoder can robustly reduce dimensions, and hence was effective in building the construct validity with a sample size as small as 100. The autoencoders could obtain a smaller mean square error and small Euclidian distance between original dataset and predictions for a small non-normal dataset. Hence, when behavioral scientists attempt to explore the construct validity of a newly designed questionnaire, an autoencoder could also be considered an alternative to a PCA.

Febrile seizures reduce hippocampal subfield volumes but not cortical thickness in children with focal onset seizures

OBJECTIVES

Whether febrile seizures (FS) produce long-term injury to the hippocampus or other brain structures is a critical question concerning focal onset seizures in children. Our aims are to evaluate the effect of FS on subfields of the hippocampus, thalamic nuclei, amygdala, cortical thickness, and surface area quantitatively in children with FS who later developed focal seizures and to identify biomarkers based on MRI structures.

METHODS

Children who had focal onset seizures with or without previous FS and normal 3-T MRI findings were included retrospectively. The MRI was performed within 2 years after the onset of focal seizures. Age-matched controls were also recruited. Hippocampal subfields and thalamic nuclei, amygdala volumes, cortical thickness, and cortical surface area in individual cortical regions were segmented by FreeSurfer version 7.1.1. Volumetric and morphometric data among children who had focal seizures with or without previous FS, as well as controls, were compared and correlated with clinical parameters.

RESULTS

Children with a history of FS who had focal seizures exhibited smaller right cornu ammonis (CA) 1 and right molecular cell layer of the hippocampus, compared to those without FS. A larger left hippocampal fissure was also found in FS with focal seizures compared to age-matched controls. There were no statistically significant differences in each nucleus of the thalamus, amygdala, cortical thickness, and surface area of each cortical region among the three groups. A smaller whole hippocampal volume was found for the right hippocampus in children with FS and focal seizures compared to those without FS. A trend of negative correlation was found between the frequency of FS and the left and right CA1 subfield volume ratios of the hippocampus.

CONCLUSIONS

We concluded that multiple episodes of FS may be associated with a trivial difference in volume reduction in the CA1 and molecular layer of the right hippocampus and an enlarged hippocampal fissure of the left hippocampus, but not with individual cortical thicknesses, surface area, thalamic nuclei, or amygdala in children with focal onset seizures.The hippocampal subfield CA1 and molecular layer of the right hippocampus may be more vulnerable than the cortices in children with focal seizures who experienced multiple FS episodes. This study highlights the minimal differences in brain volumes among children with recent onset focal seizures with or without FS history and controls, suggesting that the brain injurious aspects of the FS and recent onset focal seizures may have been previously overstated. This suggests that physicians can be reassuring about brain injury associated with these seizure types when discussing outcomes with parents and patients.

Echocardiographic study of cardiac structure and function in people with bipolar disorder after midlife

BACKGROUND

Heart failure is the leading cause of mortality in older people with bipolar disorder (BD). Studies examining cardiac structure and function in middle-aged patients with BD by using echocardiography and cardiac strain imaging are scant.

METHODS

We recruited 48 patients with bipolar I disorder (BD-I) older than 45 years to undergo conventional and tissue speckle tracking echocardiography. Data of 31 mentally healthy adults older than 45 years were randomly retrieved from the echocardiographic dataset and compared with the data of BD patients.

RESULTS

Patients with BD-I had significantly higher mean values of interventricular septal thickness (Cohen's d = 0.83, p = 0.001) and left ventricular internal diameter (Cohen's d = 0.90, p = 0.001) at end-diastole relative to controls. Additionally, BD-I patients exhibited significantly lower mean values of mitral valve E/A ratio (Cohen's d = 0.67, p = 0.007) and a more reduced global longitudinal strain (Cohen's d = 0.72, p = 0.029) than controls. Multiple linear regression revealed that body mass index was negatively correlated with the mitral valve E/A ratio (adjustment R² = 0.363, p = 0.043) in patients with BD-I.

LIMITATIONS

A relatively small sample size may limit generalization.

CONCLUSIONS

After midlife, BD patients exhibit cardiac diastolic (low mitral valve E/A ratio) and systolic (reduced global longitudinal strain) dysfunction. High body mass index may play a role in the unfavorable cardiac function in aging patients with BD.

Early Mental Trajectories Predict Different Cognitive Levels at School Age in Very Preterm Children

INTRODUCTION

Early identification of preterm children at high risk of intellectual disability (intelligence quotient [IQ] <70) or borderline intelligence (IQ = 70-84) is critical for different early intervention. We investigated whether early-life mental trajectories predict intellectual disability and borderline intelligence, respectively, among school-age preterm children.

METHODS

A multicenter study recruited preterm infants born at <32 weeks' gestation between 2001 and 2014 in Taiwan who underwent mental assessments (Bayley Scales of Infant Development) at corrected ages 6, 12, and 24 months and IQs at age 5.5 years. Mental trajectories from ages 6 to 24 months determined using group-based trajectory modeling were employed to predict intellectual disability and borderline intelligence, respectively. Model fit was assessed using the area under the receiver operating characteristic curve (AUROC) and Akaike information criterion (AIC).

RESULTS

Among the 1,680 children enrolled, three mental trajectories were identified: high-stable (59.7%), high-declining (35.3%), and low-declining (5.0%), in which the borderline-intelligence/intellectual-disability rate was 14.1%/1.5%, 36.1%/13.7%, and 10.7%/82.1%, respectively. Compared with children with normal intelligence, the low-declining trajectory had 37.7-fold higher odds (95% confidence interval [CI], 26.3-48.1) for intellectual disability, and the high-declining trajectory had 4.4-fold higher odds (95% CI, 3.1-6.1) for borderline intelligence. Compared to the models with risk factors alone (AIC 1,791.2), the models that included both risk factors and trajectory groups had better overall performance (AIC 1,419.8) and increased prediction power for intelligence outcomes: low-declining trajectory for intellectual disability (AUROC increased from 0.81 to 0.92) and high-declining trajectory for borderline intelligence (AUROC increased from 0.68 to 0.75).

CONCLUSIONS

Early-life mental trajectories help identify preterm children at risk of intellectual disability and borderline intelligence, respectively, at school age for timely intervention.

Retinopathy of Prematurity Is a Biomarker for Pathological Processes in the Immature Brain

INTRODUCTION

Retinopathy of prematurity (ROP) is considered a neurovascular disease. We investigated whether ROP, mild or severe, is associated with neurodevelopmental impairment (NDI) in extremely preterm children.

METHODS

We conducted a multicenter retrospective cohort study in southern Taiwan. A total of 394 children <28 weeks of gestation who survived to discharge from 2011 to 2018 received neurodevelopmental assessment at corrected age of 24 months. Severe ROP was defined as ROP of stages 2 plus or worse, or recipients of retinal therapy, and mild ROP as stage 1 or 2 in at least one eye. NDI was defined as cognitive or motor impairment using the Bayley Scales of Infant and Toddler Development, moderate to severe cerebral palsy, or profound hearing loss.

RESULTS

Among the 374 children validated for analysis, 157 children (42%) had non-ROP, 145 (39%) mild ROP, and 72 (19%) severe ROP. As ROP severity increased progressively from non-ROP, to mild ROP, and to severe ROP, the rates of NDI increased from 25%, to 46%, and to 61%. The multivariable logistic regression showed that the model included three levels of ROP, and neonatal morbidities achieved better overall performance for NDI than the model that included neonatal morbidities alone. Compared with non-ROP, mild ROP and severe ROP had adjusted odds ratios of 1.90 (95% CI: 1.10-3.28) and 2.75 (95% CI: 1.33-5.67) for NDI, respectively.

CONCLUSION

Mild ROP and severe ROP are independent neonatal morbidities associated with NDI. Neurodevelopmental follow-up of extremely preterm children with any stage of ROP is needed.

Comparison of Robotic and Conventional Unicompartmental Knee Arthroplasty Outcomes in Patients with Osteoarthritis: A Retrospective Cohort Study

Robotic-arm-assisted unicompartmental knee arthroplasty (RUKA) was developed to increase the accuracy of bone alignment and implant positioning. This retrospective study explored whether RUKA has more favorable overall outcomes than conventional unicompartmental knee arthroplasty (CUKA). A total of 158 patients with medial compartment osteoarthritis were recruited, of which 85 had undergone RUKA with the Mako system and 73 had undergone CUKA. The accuracy of component positioning and bone anatomical alignment was compared using preoperative and postoperative radiograph. Clinical outcomes were evaluated using questionnaires, which the patients completed preoperatively and then postoperatively at six months, one year, and two years. In total, 52 patients from the RUKA group and 61 from the CUKA group were eligible for analysis. The preoperative health scores and Kellgren-Lawrence scores were higher in the RUKA group. RUKA exhibited higher implant positioning accuracy, thus providing a superior femoral implant angle, properly aligned implant placement, and a low rate of overhang. RUKA also achieved higher accuracy in bone anatomical alignment (tibial axis angle and anatomical axis angle) than CUKA, but surgical time was longer, and blood loss was greater. No significant differences were observed in the clinical outcomes of the two procedures.

Mediating Effects of Coping Strategies on the Relationship Between Mental Health and Quality of Life Among Indonesian Female Migrant Workers in Taiwan

INTRODUCTION

Mental health is a major concern among migrant workers worldwide. More than 200,846 female migrant workers in Taiwan are from Indonesia. The study's purpose was to investigate mediating effects of coping strategies on the relationship between mental health problems and the quality of life (QoL).

METHOD

This cross-sectional study was conducted in Taiwan. In total, 500 Indonesian female migrant workers completed four questionnaires. A mediation test was conducted to estimate direct and indirect effects.

RESULTS

Coping strategies, namely substance use, behavioral disengagement, denial, and religious dedication, partially mediated the relationship between mental health problems (depression, anxiety, and stress) and QoL among Indonesian female migrant workers in Taiwan.

DISCUSSION

Health promotion programs should be developed for Indonesian female migrant workers in Taiwan to help them detect and overcome their mental health problems. Interventions that facilitate effective coping strategies should be administered to improve their QoL.

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.

Associations of Genetic Variants of Methylenetetrahydrofolate Reductase and Serum Folate Levels with Metabolic Parameters in Patients with Schizophrenia

The one-carbon metabolism pathway is a suitable candidate for studying the genetic and epigenetic factors contributing to metabolic abnormalities in patients with schizophrenia. We recruited 232 patients with schizophrenia and analyzed their serum folate, vitamin B12, and homocysteine levels and metabolic parameters to investigate the associations of genetic variants of methylenetetrahydrofolate reductase (MTHFR) and folate levels with metabolic parameters. MTHFR C677T and MTHFR A1298C were genotyped. Results showed that MTHFR 677T allele carriers had lower levels of total cholesterol and low-density lipoprotein cholesterol than those with the 677CC genotype. Metabolic parameters did not differ between MTHFR 1298C and 1298AA carriers. Patients with a low folate level had a lower high-density lipoprotein cholesterol level than those with a normal folate level, but the effect disappeared after adjustment for age, sex, and types of antipsychotics used. We found significant interactions between MTHFR A1298C and the folate level status (low vs. normal) in terms of body mass index and waist circumference. In conclusion, genetic variants in one-carbon metabolism might play a role in antipsychotic-induced metabolic abnormalities. Prospective studies on drug-naïve, first-episode patients with schizophrenia are warranted to identify key regions of DNA methylation changes accounting for antipsychotic-induced metabolic abnormalities.

Relationship between rotating shift work and white blood cell count, white blood cell differential count, obesity, and metabolic syndrome of nurses

This study investigated the relationship between working rotating shifts and white blood cell (WBC) count, WBC differential count (DC), obesity, and metabolic syndrome of nurses. Samples were obtained from a total of 720 nurses who had received health checkups at a large teaching hospital in Taiwan. Among these nurses, 500 worked rotating shifts, and the remaining 220 nurses worked fixed daytime shifts. We used binary logistic regression to identify the risk factors of obesity or metabolic syndrome. The results indicate that nurses working rotating shifts had a significantly higher WBC count than those working fixed daytime shifts. WBC count was an independent factor relating to an overly large waist circumference or overly high body mass index (BMI) of nurses. For every 10³/μL increase in WBC count, the risk of waist circumference exceeding 90 cm and 80 cm respectively in male and female nurses increased by 46%, and for every 10³/μL increase in WBC count, the risk of a BMI 24 kg/m² in nurses increased by 50%. Similarly, WBC count and work type were independent factors influencing the metabolic syndrome of nurses. For every 10³/μL increase in WBC count, the risk of metabolic syndrome occurring in nurses increased by 65%. Nurses working rotating shifts were at a 3.34 times greater risk of having metabolic syndrome than those working fixed daytime shifts. The mean age of our participants was 29.54 years old, and only approximately 4% of the participants had metabolic syndrome. Among these nurses, we found that high WBC was correlated with an overly large waist circumference and overly high BMI. Furthermore, the nurses working rotating shifts may have been at greater risk of metabolic syndrome than those working fixed daytime shifts, and increases in WBC were also associated with the occurrence of metabolic syndrome.

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.

Maternal Immune Activation Causes Social Behavior Deficits and Hypomyelination in Male Rat Offspring with an Autism-Like Microbiota Profile

Maternal immune activation (MIA) increases the risk of autism spectrum disorder (ASD) in offspring. Microbial dysbiosis is associated with ASD symptoms. However, the alterations in the brain-gut-microbiota axis in lipopolysaccharide (LPS)-induced MIA offspring remain unclear. Here, we examined the social behavior, anxiety-like and repetitive behavior, microbiota profile, and myelination levels in LPS-induced MIA rat offspring. Compared with control offspring, MIA male rat offspring spent less time in an active social interaction with stranger rats, displayed more anxiety-like and repetitive behavior, and had more hypomyelination in the prefrontal cortex and thalamic nucleus. A fecal microbiota analysis revealed that MIA offspring had a higher abundance of Alistipes, Fusobacterium, and Ruminococcus and a lower abundance of Coprococcus, Erysipelotrichaies, and Actinobacteria than control offspring, which is consistent with that of humans with ASD. The least absolute shrinkage and selection operator (LASSO) method was applied to determine the relative importance of the microbiota, which indicated that the abundance of Alistipes and Actinobacteria was the most relevant for the profile of defective social behavior, whereas Fusobacterium and Coprococcus was associated with anxiety-like and repetitive behavior. In summary, LPS-induced MIA offspring showed an abnormal brain-gut-microbiota axis with social behavior deficits, anxiety-like and repetitive behavior, hypomyelination, and an ASD-like microbiota profile.

Pterostilbene Increases LDL Metabolism in HL-1 Cardiomyocytes by Modulating the PCSK9/HNF1α/SREBP2/LDLR Signaling Cascade, Upregulating Epigenetic hsa-miR-335 and hsa-miR-6825, and LDL Receptor Expression

Proprotein convertase subtilisin/kexin type 9 (PCSK9) can promote the degradation of low-density lipoprotein (LDL) receptor (LDLR), leading to hypercholesterolemia and myocardial dysfunction. The intracellular regulatory mechanism by which the natural polyphenol pterostilbene modulates the PCSK9/LDLR signaling pathway in cardiomyocytes has not been evaluated. We conducted Western blotting, flow cytometry, immunofluorescence staining, and mean fluorescence intensity analyses of pterostilbene-treated mouse HL-1 cardiomyocytes. Pterostilbene did not alter cardiomyocyte viability. Compared to the control group, treatment with both 2.5 and 5 μM pterostilbene significantly increased the LDLR protein expression accompanied by increased uptake of LDL. The expression of the mature PCSK9 was significantly suppressed at the protein and mRNA level by the treatment with both 2.5 and 5 μM pterostilbene, respectively, compared to the control. Furthermore, 2.5 and 5 μM pterostilbene treatment resulted in a significant reduction in the protein hepatic nuclear factor 1α (HNF1α)/histone deacetylase 2 (HDAC2) ratio and sterol regulatory element-binding protein-2 (SREBP2)/HDAC2 ratio. The expression of both hypoxia-inducible factor-1 α (HIF1α) and nuclear factor erythroid 2-related factor 2 (Nrf2) at the protein level was also suppressed. Pterostilbene as compared to short hairpin RNA against SREBP2 induced a higher protein expression of LDLR and lower nuclear accumulation of HNF1α and SREBP2. In addition, pterostilbene reduced PCSK9/SREBP2 interaction and mRNA expression by increasing the expression of hsa-miR-335 and hsa-miR-6825, which, in turn, increased LDLR mRNA expression. In cardiomyocytes, pterostilbene dose-dependently decreases and increases the protein and mRNA expression of PCSK9 and LDLR, respectively, by suppressing four transcription factors, HNF1α, SREBP2, HIF1α, and Nrf2, and enhancing the expression of hsa-miR-335 and hsa-miR-6825, which suppress PCSK9/SREBP2 interaction.

Small blood stem cells for enhancing early osseointegration formation on dental implants: a human phase I safety study

Background

Small blood stem cells (SB cells), isolated from human peripheral blood, demonstrated the ability to benefit bone regeneration and osseointegration. The primary goal of our study is to examine the safety and tolerability of SB cells in dental implantation for human patients with severe bone defects.

Methods

Nine patients were enrolled and divided into three groups with SB cell treatment doses of 1 × 10⁵, 1 × 10⁶, and 1 × 10⁷ SB cells, and then evaluated by computed tomography (CT) scans to assess bone mineral density (BMD) by Hounsfield units (HU) scoring. Testing was conducted before treatment and on weeks 4, 6, 8, and 12 post dental implantation. Blood and comprehensive chemistry panel testing were also performed.

Results

No severe adverse effects were observed for up to 6-month trial. Grade 1 leukocytosis, anemia, and elevated liver function were observed, but related with the patient’s condition or the implant treatment itself and not the transplantation of SB cells. The levels of cytokines and chemokines were detected by a multiplex immunological assay. Elevated levels of eotaxin, FGF2, MCP-1, MDC, and IL17a were found among patients who received SB cell treatment. This observation suggested SB cells triggered cytokines and chemokines for local tissue repair. To ensure the efficacy of SB cells in dental implantation, the BMD and maximum stresses via stress analysis model were measured through CT scanning. All patients who suffered from severe bone defect showed improvement from D3 level to D1 or D2 level. The HU score acceleration can be observed by week 2 after guided bone regeneration (GBR) and prior to dental implantation.

Conclusions

This phase I study shows that treatment of SB cells for dental implantation is well tolerated with no major adverse effects. The use of SB cells for accelerating the osseointegration in high-risk dental implant patients warrants further phase II studies.
