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.

Genome-wide association studies (GWAS) in predominately European-ancestry (EUR) populations have identified numerous genetic variants associated with adiposity-related traits. An emerging challenge is the limited transferability of genetic scores constructed based on GWAS results from one ancestry for trait prediction in other ancestries. We performed trans-ancestry meta-analysis (TAMA) for eight adiposity-related traits using genetic data from 96,124 East Asian (EAS) and 443,359 EUR individuals. We identified >1400 genomic regions significantly associated with one or more traits. Despite EAS comprising only ~20% of the study population, genetic scores constructed from the trans-ancestry (TA) results accounted for between 30% and 79% more variation in the adiposity traits in EAS compared with scores derived from the EUR GWAS alone. Furthermore, TA scores also modestly improved variance explained in African/African American, Hispanic and South Asian populations. Our findings highlight the utility of TAMA for increasing variance explained by genetic scores across populations of different ancestries.

Chronic spontaneous urticaria (CSU) is the most common phenotype of chronic urticaria. We compared treatment effects and safety profiles of the medications in patients with CSU. We searched PubMed, MEDLINE, and Web of Science for randomized control trials (RCTs), from 1 January 2000 to 31 July 2021, which evaluated omalizumab and immunosuppressants. Network meta-analyses (NMAs) were performed with a frequentist approach. Outcome assessments considered the efficacy (Dermatology Life Quality Index (DLQI) and weekly urticaria activity score (UAS7)) and tolerability profiles with evaluations of study quality, inconsistencies, and heterogeneity. We identified 14 studies which we included in our direct and indirect quantitative analyses. Omalizumab demonstrated better efficacy in DLQI and UAS7 outcomes compared to a placebo, and UAS7 assessments also demonstrated better outcomes compared to cyclosporine. Alongside this, omalizumab demonstrated relatively lower incidences of safety concerns compared to the other immunosuppressants. Cyclosporin was also associated with higher odds of adverse events than other treatment options. Our findings indicate that omalizumab resulted in greater improvements in terms of the DLQI and UAS7 with good tolerability in CSU patients compared to the other immunosuppressants.

PURPOSE We performed this study to evaluate the effect of back bracing to treat patients with chronic low back pain. METHODS This was a prospective, unblinded, randomized controlled trial of 61 adults with uncomplicated chronic low back pain (>12 wks) and imaging findings of degenerative spondylosis, to assess the effectiveness of a semirigid back brace. All study participants received back school instruction. The treatment group also received a lumbar orthosis and was instructed to wear it as needed for symptom relief. At baseline, 6 wks, 12 wks, and 6 mos after intervention, we collected: Numerical Rating Scale to measure pain intensity, Pain Disability Questionnaire, Patient-Reported Outcome Measurement Information System, and EuroQol 5-Dimension (EQ-5D) to measure patient-reported function and quality of life. RESULTS An interim analysis at the halfway point in enrollment (61 of 120 planned participants) revealed the Pain Disability Questionnaire, Patient-Reported Outcome Measurement Information System, and EQ-5D scores in the treatment group to be worse than in the control group, but no significant group differences in Numerical Rating Scale scores. Outcome differences between groups analyzed over time revealed (effect [P]): Pain Disability Questionnaire = 0.84 (0.04); Patient-Reported Outcome Measurement Information System = 0.78 (0.005); EQ-5D = 0.06 (0.01); and Numerical Rating Scale = 0.02 (0.6). We halted the study because continuation was unlikely to produce significant changes to the results. CONCLUSIONS In patients with uncomplicated chronic low back pain, a back brace when combined with education and exercise instruction did not provide any pain relief compared with education and exercise instruction alone.

Ultrashort pulsed laser is a promising tool for processing transparent materials. We report on a new approach that simultaneously creates a pair of conjugate grooves on the bottom surface of a thin glass substrate at the duration of plowing a V-shaped microgroove on the top surface using the technique of direct laser ablation. We propose a hypothesis to explain the accompanying grooves’ formation mechanism and simulate Maxwell’s equations to verify its applicability. Measurements showed the surface roughness of the groove’s sidewalls was 0.14 $\mu \text{m}$ . This method requires no mask, can be directly performed in the atmosphere, and can simultaneously produce microgrooves on both sides of the substrate that render it an effective approach for producing high quality V-shaped microgrooves on both sides of the substrate.

Laser machining has been emerging as a powerful alternative for cutting thin metal substrates. In this study, the application of pulsed laser cutting of a thin nonoriented silicon steel, with a thickness of 0.1 mm, was studied. The four processing parameters considered were laser power, cutting speed, pulse repetition rate, and processing environment. The two outputs to be measured were the extent of heat-affected zone (HAZ) and deviation of magnetic flux density (MFD) from initial value. Each input was designed with three levels and the three processing environments were air, deionized water, and sodium chloride solution. Based on the experimental design of the L27 Taguchi method, 27 parameter sets out of the total of 81 sets were used for the experiment. Results show that HAZ and MFD were negatively correlated. Compared with processing in air, cutting in the liquid could effectively reduce the HAZ. In the 27 experimental cases, the achieved minimum HAZ was 34.5 μm that corresponded to retaining 99% of initial MFD. The importance of the input was analyzed by the random forest method. The most and second significant parameters were laser power and environmental condition and their importance levels were 50.82% and 40.99%, respectively. Four artificial intelligence (AI) prediction models, full quadratic multiple regression analysis, artificial neural network, random forest, and extreme learning machine (ELM), were established based on randomly selecting 80% of the 27 data sets for training and the remaining 20% for testing. Model verification was executed by arbitrarily taking 10 additional new predictive parameter sets, from the remaining 54 parameter sets, for experiments. After comparing the predicting and experimental results, ELM model was found to have the best forecast performance. Thus, it was chosen as the target model for output optimization by the genetic algorithm method (GA). Through implementing the predicted optimal processing parameters from the resulting ELM-GA algorithm for the confirmation experiment, the obtained MFD and HAZ were 1.639 T and 30.41 μm, respectively, which were very close to that of the predicted optimal outputs, 1.640 T for MFD and 29.90 μm for HAZ.

Background: Craniopharyngiomas are benign tumors of embryologic origin located in the sellar region. Patients have both neurological and endocrinological symptoms. Symptoms may be subtle in the early clinical course, which leads to delayed diagnosis. This study evaluated the clinical and endocrinological manifestations of childhood-onset craniopharyngioma. Methods: We retrospectively reviewed medical records of 45 children diagnosed as having craniopharyngioma between 1995 and 2019. We collected data on clinical symptoms and signs, height, weight, biochemical and hormone data, images, operation records, and pathology reports. A three-graded classification system was applied to define the degree of hypothalamic damage (HD). We analyzed clinical and endocrinological manifestations among patients with and without obesity, with short and normal stature, and with differing degrees of HD. Results: Clinical endocrinologic manifestations included adrenocortical insufficiency (42%), central hypothyroidism (37%), short stature (31%), obesity (20%), weight

Phosphofurin Acidic Cluster Sorting Protein 2 (PACS2)-related early infantile developmental and epileptic encephalopathy (EIDEE) is a rare neurodevelopmental disorder. EIDEE is characterized by seizures that begin during the first three months of life and are accompanied by developmental impairment over time. In this article, we present three patients with EIDEE who experienced neonatal-onset seizures that developed into intractable seizures during infancy. Whole exome sequencing revealed a de novo heterozygous missense variant in all three patients in the p.Glu209Lys variant of the PACS2 gene. We conducted a literature review and found 29 cases to characterize the seizure patterns, neuroimaging features, the usage of anticonvulsants, and the clinical neurodevelopmental outcomes of PACS2-related EIDEE. The seizures were characterized by brief, recurring tonic seizures in the upper limbs, sometimes accompanied by autonomic features. Neuroimaging abnormalities were observed in the posterior fossa region, including mega cisterna magna, cerebellar dysplasia, and vermian hypoplasia. The long-term prognosis ranges from low–average intelligence to severe developmental retardation, emphasizing the importance of early recognition and accurate diagnosis by pediatric neurologists to provide personalized patient management.

BACKGROUND Lack of evidence regarding whether a useful examination instrument such as an multiple choice question (MCQ) quiz is reliable for assessing delirium care knowledge. AIM To develop and psychometrically test a MCQ-based quiz for assessing the delirium care knowledge in critical care nurses. DESIGN Instrument development and psychometric evaluation study. METHODS The development and validation process consisted of two phases. The first Phase focused on the quiz development, which was achieved through the following steps: (a) generation of an initial 20-item pool; (b) assessment of content validity; (c) assessment of face validity; (d) conduction of a pilot test, involving the collection of data from 217 critical care nurses through an online survey; and (e) item analysis and item elimination according to item difficulty and discrimination indices. The MCQ quiz was finalized through the development process. The second phase emphasized quiz validation through estimation of the internal consistency, split-half and test-retest reliability, and construct validity using parallel analysis with exploratory factor analysis (EFA). RESULTS A final 16-item MCQ quiz was emerged from the item analysis. The Kuder-Richardson formula 20 coefficient for the overall quiz indicated good internal consistency (0.85), and the intraclass correlation coefficient with a 30-day interval also indicated that the questionnaire had satisfactory stability (0.97). EFA confirmed that the quiz had appropriate construct validity, and four factors could explain 60.87% of the total variance. CONCLUSION In this study, the MCQ, and single best answer quiz for assessing delirium care knowledge was developed, and its reliability and validity for this purpose were demonstrated. RELEVANCE TO CLINICAL PRACTICE This study introduced an evidence-based quiz designed for future use in delirium care research and education that has significant implications for MCQ-based knowledge assessment in clinical practice.

Objective The aim of this study was to evaluate the changes in the prevalence of myopia in Taiwanese schoolchildren over the past few decades and to analyze the risk factors for myopia. Design Analysis of eight consecutive population-based myopia surveys conducted from 1983 to 2017. Participants An average of 8916 (5019–11178) schoolchildren aged 3 to 18 years were selected using stratified systematic cluster sampling or by probability proportional to size sampling. Methods All participants underwent complete ophthalmic evaluations. Three drops of 0.5% tropicamide were used to obtain cycloplegic refractive status of each participant. Questionnaires were used to acquire participant data from the 1995, 2005, 2010, and 2016 surveys. Main Outcome Measures Prevalence of myopia (spherical equivalence of ≤−0.25 D) and high myopia (≤−6.0 D) was assessed. Multivariable analyses of risk factors were conducted. Results The prevalence of myopia among all age groups increased steadily. From 1983 to 2017, the weighted prevalence increased from 5.37% (95% confidence interval (CI), 3.5%-7.2%) to 25.4% (95% CI, 21.3%-29.6%) for seven-year-olds (P = .001 for trend), and from 30.7% (95% CI, 26.9%-34.4%) to 76.7% (95% CI, 72.9%-80.4%) for 12-year-olds (P = .001 for trend). The prevalence of high myopia also increased from 1.39% (95% CI, 0.4%-2.4%) to 4.26% (95% CI, 3.4%-5.2%) for 12-year-olds (P = .008 for trend) and from 4.37% (95% CI, 2.9%-5.8%) to 15.4% (95% CI, 13.8%-16.9%) for 15-year-olds (P = .039 for trend). In both the 2005 and 2016 survey samples, children who spent less than 180 minutes daily on near-work activities had significantly lower risks for developing myopia ( Conclusions The prevalence of myopia increased rapidly from 1983 to 2017 in Taiwan. The major risk factors for myopia among schoolchildren are older age and time spent on near-work activities; use of electronic devices increased the amount of time spent on near-work and may increase the risk of developing myopia.

A recent increase in screen time during early childhood has adversely affected the sleep and psychosocial health of children; however, limited information is available regarding effective interventions to reduce the screen time among them. This study aimed to investigate the effect of a parental educational program on screen use, sleep quality, and psychosocial adaptation among preschoolers.A clustered randomized controlled study with a parallel-group design was conducted. Preschoolers with a screen time of ≥2 h/day and their parents were recruited. In total, 14 kindergartens containing 129 parent-child dyads were randomly allocated to either the experimental group (receiving parental education, N = 63 dyads) or the control group (daily activities, N = 66 dyads). Data were collected before and after the intervention. A screen time questionnaire, the Children's Sleep Habits Questionnaire, and the Pediatric Symptom checklist-17 were provided to the participants. A linear mixed-model analysis was performed to examine the efficacy of the intervention.After the intervention, the screen time of children in the experimental group was significantly reduced (effect size: 0.83, p .001), and they presented improved sleep quality (effect size: 0.57, p = .01) and attention score (effect size: 0.77, p = .02) for psychosocial adaptation.Parental education is an effective intervention for reducing screen time and improving sleep quality and attention among preschoolers.Healthcare professionals should consider implementing parental educational programs to reduce screen time, and thus improve the sleep quality and psychosocial health of preschoolers.

Background: Patients with epilepsy have a higher mortality rate than the general population. Up-to-date estimates of epilepsy incidence, prevalence, and medication use are critical to assist policymaking. Methods: Using the National Taiwan Insurance Research Database, the standardized incidence and prevalence of epilepsy were estimated in each calendar year from 2007 to 2015. We used the incident cases of epilepsy to analyze the change in prescribing patterns from 2007 to 2015. Joinpoint regression was used to estimate secular trends. Results: From 2007 to 2015, the age- and sex-standardized incidence decreased from 0.72 (95% confidence interval [CI] 0.70–0.73) to 0.54 (95% CI 0.53–0.55) per 1,000 person-years, giving an annual percentage change (APC) of −2.73 (p < 0.05). Among patients younger than 20 years, the incidence did not change significantly. The age- and sex-standardized prevalence decreased from 6.94 (95% CI 6.90–6.98) to 6.86 (95% CI, 6.82–6.89) per 1,000 people, giving an APC of −0.31 (p < 0.05). However, the prevalence increased in the 35- to 49- and 50- to 64-year age-groups. The most common first-line anticonvulsant was phenytoin in 2007 and valproate in 2015. The use of levetiracetam, clobazam, and valproate increased during the study period, with APCs of 25.48% (95% CI 19.97–31.24), 6.41 (3.09–9.85), and 2.83 (1.51–4.16), respectively. The use of carbamazepine, phenytoin, and topiramate decreased; the APCs were −23.86% (95% CI −25.25 to −22.44), −6.61 (−8.40 to −4.79), and −4.29% (−7.87 to −0.57), respectively. Conclusions: The overall prevalence and incidence of epilepsy decreased slightly from 2007 to 2015. The prescribed first-line anticonvulsant also changed over time.

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

Background: Vagus nerve stimulation (VNS) is used as an add-on treatment for epilepsy. This study aimed to use Taiwanese nationwide registry data to analyze the therapeutic effects of VNS in children with refractory epilepsy (RE) and try to explore predictive factors of VNS treatment effectiveness. Methods: This retrospective study collected data from December 2007 to December 2014. Patient variables included gender, age, VNS implantation date, epilepsy duration, seizure frequency, seizure type, etiology, and antiepileptic drug (AED) history. We divided patients into three groups: Group I as seizure frequency >80 times per month, Group II as seizure frequency 24–80 times per month, and Group III as seizure frequency

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.

Lung function impairment underlies chronic obstructive pulmonary disease (COPD) and predicts mortality. In the largest multi-ancestry GWAS meta-analysis of lung function to date, comprising 580,869 participants, 1020 independent association signals identified 559 genes supported by ≥2 criteria from a systematic variant-to-gene mapping framework. These genes were enriched in 29 pathways. Individual variants showed heterogeneity across ancestries, age and smoking groups, and collectively as a genetic risk score (GRS) showed strong association with COPD across ancestry groups. We undertook phenome-wide association studies (PheWAS) for selected associated variants, and trait and pathway-specific GRS to infer possible consequences of intervening in pathways underlying lung function. We highlight new putative causal variants, genes, proteins and pathways, including those targeted by existing drugs. These findings bring us closer to understanding the mechanisms underlying lung function and COPD, and should inform functional genomics experiments and potentially future COPD therapies.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is an emerging virus responsible for the ongoing COVID-19 pandemic. SARS-CoV-2 binds to the human cell receptor angiotensin-converting enzyme 2 (ACE2) through its receptor-binding domain in the S1 subunit of the spike protein (S1-RBD). The serum levels of autoantibodies against ACE2 are significantly higher in patients with COVID-19 than in controls and are associated with disease severity. However, the mechanisms through which these anti-ACE2 antibodies are induced during SARS-CoV-2 infection are unclear. In this study, we confirmed the increase in antibodies against ACE2 in patients with COVID-19 and found a positive correlation between the amounts of antibodies against ACE2 and S1-RBD. Moreover, antibody binding to ACE2 was significantly decreased in the sera of some COVID-19 patients after preadsorption of the sera with S1-RBD, which indicated that antibodies against S1-RBD can cross-react with ACE2. To confirm this possibility, two monoclonal antibodies (mAbs 127 and 150) which could bind to both S1-RBD and ACE2 were isolated from S1-RBD-immunized mice. Measurement of the binding affinities by Biacore showed these two mAbs bind to ACE2 much weaker than binding to S1-RBD. Epitope mapping using synthetic overlapping peptides and hydrogen deuterium exchange mass spectrometry (HDX-MS) revealed that the amino acid residues P463, F464, E465, R466, D467 and E471 of S1-RBD are critical for the recognition by mAbs 127 and 150. In addition, Western blotting analysis showed that these mAbs could recognize ACE2 only in native but not denatured form, indicating the ACE2 epitopes recognized by these mAbs were conformation-dependent. The protein–protein interaction between ACE2 and the higher affinity mAb 127 was analyzed by HDX-MS and visualized by negative-stain transmission electron microscopy imaging combined with antigen-antibody docking. Together, our results suggest that ACE2-cross-reactive anti-S1-RBD antibodies can be induced during SARS-CoV-2 infection due to potential antigenic cross-reactivity between S1-RBD and its receptor ACE2.

Takotsubo syndrome (TTS) is characterized angiographically by transient left ventricular systolic dysfunction sparing the basal segments of the left ventricle and absence of obstructive coronary artery disease. Epileptic seizures as triggering events for TTS are uncommon, having only been described in approximately 100 previous cases Case report: A 64-year-old woman with a history of recent stroke-related seizures was admitted for an acute onset of right hemiparesis with dull response. Neurological examination revealed a forced deviation of the eyeballs to the left side and quadriplegia. No large intracranial artery occlusion was disclosed through computed tomography angiography, but an acute infarction at the right corona radiata was identified through magnetic resonance imaging. Electroencephalography showed frequent spike-and-wave complexes over the right cerebral hemisphere indicating subtle status epilepticus. Her consciousness deteriorated to a stuporous state, and her eyeballs were forced deviated to the right side with persistent twitching of the right limbs 10 hours later. The convulsive status epilepticus (CSE) subsided after intravenous infusion of midazolam. However, atrial flutter with inverted T-wave and elevated high-sensitivity troponin I were observed 12 hours after CSE. Arrhythmia was soon alleviated through appropriate treatment. A further coronary angiography did not show significant coronary artery stenosis but indicated that the midsection and the apex of the left ventricle ballooned out during systole as the base contracted normally, indicating a Takotsubo syndrome.Physicians need to monitor unusual arrhythmias, particularly atrial and ventricular arrhythmias, for the possibility of TTS in patients with epileptic seizure.

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.We conducted a multicenter retrospective cohort study in southern Taiwan. A total of 394 children28 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.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.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.

Carotid atherosclerosis is associated with cardiovascular and cerebrovascular events. We explored an appropriate method for selecting participants without ischemic cerebrovascular disease but with various comorbidities eligible for a carotid ultrasound. This was a retrospective subgroup analysis of the carotid plaque burden from a previous study involving a vascular and cognitive survey of 956 elderly recycling volunteers (778 women and 178 men; mean age: 70.8 years). We used carotid ultrasound to detect the carotid plaque and computed the carotid plaque score (CPS). A moderate or high degree of carotid atherosclerosis (MHCA) was defined as CPS > 5 and was observed in 22% of the participants. The CPS had positive linear correlations with age, systolic blood pressure, and fasting glucose. We stratified the participants into four age groups: 60–69, 70–74, 75–79, and ≥80 years. Multivariable analysis revealed that significant predictors for MHCA were age, male sex, hypertension, diabetes mellitus, hyperlipidemia, coronary artery disease, and a nonvegetarian diet. Coronary artery disease and advanced age were the two strongest predictors. We chose the aforementioned seven significant predictors to establish a nomogram for MHCA prediction. The area under the receiver operating characteristic curve in internal validation with 10-fold cross-validation and the classification accuracy of the nomogram were 0.785 and 0.797, respectively. We presumed people who have a ≥50% probability of MHCA warranted a carotid ultrasound. A flowchart table derived from the nomogram addressing the probabilities of all models of combinations of comorbidities was established to identify participants who had a probability of MHCA ≥ 50% (corresponding to a total nomogram score of ≥15 points). We further established a carotid risk score range from 0 to 17 comprising the seven predictors. A carotid risk score ≥ 7 was the most optimal cutoff value associated with a probability of MHCA ≥ 50%. Both total nomogram score ≥ 15 points and carotid risk score ≥ 7 can help in the rapid identification of individuals without stroke but who have a ≥50% probability of MHCA—these individuals should schedule a carotid ultrasound.

Background: Dementia and depression have emerged as two of the major mental health concerns for elderly people, which are likely to substantially affect public health in the coming decades. Both dementia and geriatric depression are associated with increased morbidity, health care utilization, and mortality. Early detection and treatment initiation are some of the best strategies to minimize the ill effects of dementia and depression on the elderly people. To this end, large-scale screening may be the first step.Methods: Screening of individuals ≥65 years old was conducted in the outpatient department of a university hospital. Ascertainment of dementia 8 (AD8) and five-item Brief Symptom Rating Scale (BSRS-5) were used to screen for cognitive decline and depression, respectively.Findings: In total, 3079 elderly people completed both AD8 and BSRS-5. Patients tested positive for cognitive impairment and depression were 28.2% and 15%, respectively. However, 7% were tested positive by both AD8 and BSRS-5 and with statistical significance.Interpretation: The high ratio of suspected dementia and suspected depression suggested the needs and cost-effect of screening among the elderly outpatients. However, the statistically significant overlap implied potential bias when screening only one condition. Future screening program of geriatric mental health needs to consider this.

Background: During the period of 2016~2018, many efforts were put into promoting the Patient Autonomy Act (PAA) in Taiwan, such as nationally sponsoring advertisements, promoting campaigns, and conducting in-service training programs for healthcare providers. However, no study has examined the impacts of promoting the PAA on healthcare providers. This study was designed to investigate healthcare providers’ knowledge of palliative care and perceptions of palliative care barriers before and after promoting the PAA. Methods: A cross-sectional design was conducted in 2013 and 2018 respectively that used a self-reporting questionnaire to examine healthcare providers’ knowledge of palliative care and perceived barriers to providing palliative care. One hospital recruited 277 healthcare providers in 2013 and 222 healthcare providers in 2018 in another hospital. Statistical analyses involved descriptive statistics for demographic characters. Multivariate linear regression analyses were used to identify predictors of knowledge of and perceived barriers to palliative care. A principal component analysis was to identify the most appropriate factorial structure for the contents of knowledge and perceived barriers to palliative care. Results: Three factors related to knowledge of palliative care were identified in both 2013 and 2018 data: ‘policy, regulation, and promotion’, ‘philosophy and treatments’, and ‘myths and misunderstandings’. Study findings in the two periods were similar. As for barriers to providing palliative care, three factors were identified in 2013 of ‘quality palliative care’, ‘palliative care difficulties’ and ‘messaging and communication’, and in 2018 of ‘messaging and information’, ‘knowledge and attitudes’ and ‘quality palliative care’ were identified. Study findings differed between the two periods. Conclusion: After implementation of the PAA, perceived barriers changed. Policies can better reinforce mitigating strategies—including opportunities for education, shared decision-making, and changes in institutions and care systems. Also, assessing barriers creates important opportunities for further research to address the most critical aspects to improving end-of-life care for patients and their families.

Background Tobacco smoking is estimated to account for more than 1 million annual deaths in China, and the epidemic continues to increase in men. Large nationwide prospective studies linked to different health records can help to periodically assess disease burden attributed to smoking. We aimed to examine associations of smoking with incidence of and mortality from an extensive range of diseases in China. Methods We analysed data from the prospective China Kadoorie Biobank, which recruited 512 726 adults aged 30–79 years, of whom 210 201 were men and 302 525 were women. Participants who had no major disabilities were identified through local residential records in 100–150 administrative units, which were randomly selected by use of multistage cluster sampling, from each of the ten diverse study areas of China. They were invited and recruited between June 25, 2004, and July 15, 2008. Upon study entry, trained health workers administered a questionnaire assessing detailed smoking behaviours and other key characteristics (eg, sociodemographics, lifestyle, and medical history). Participants were followed up via electronic record linkages to death and disease registries and health insurance databases, from baseline to Jan 1, 2018. During a median 11-year follow-up (IQR 10–12), 285 542 (55·7%) participants were ever hospitalised, 48 869 (9·5%) died, and 5252 (1·0%) were lost to follow-up during the age-at-risk of 35–84 years. Cox regression yielded hazard ratios (HRs) associating smoking with disease incidence and mortality, adjusting for multiple testing. Findings At baseline, 74·3% of men and 3·2% of women (overall 32·4%) ever smoked regularly. During follow-up, 1 137 603 International Classification of Diseases, 10th revision (ICD-10)-coded incident events occurred, involving 476 distinct conditions and 85 causes of death, each with at least 100 cases. Compared with never-regular smokers, ever-regular smokers had significantly higher risks for nine of 18 ICD-10 chapters examined at age-at-risk of 35–84 years. For individual conditions, smokers had significantly higher risks of 56 diseases (50 for men and 24 for women) and 22 causes of death (17 for men and nine for women). Among men, ever-regular smokers had an HR of 1·09 (95% CI 1·08–1·11) for any disease incidence when compared with never-regular smokers, and significantly more episodes and longer duration of hospitalisation, particularly those due to cancer and respiratory diseases. For overall mortality, the HRs were greater in men from urban areas than in men from rural areas (1·50 [1·42–1·58] vs 1·25 [1·20–1·30]). Among men from urban areas who began smoking at younger than 18 years, the HRs were 2·06 (1·89–2·24) for overall mortality and 1·32 (1·27–1·37) for any disease incidence. In this population, 19·6% of male (24·3% of men residing in urban settings and 16·2% of men residing in rural settings) and 2·8% of female deaths were attributed to ever-regular smoking. Interpretation Among Chinese adults, smoking was associated with higher risks of morbidity and mortality from a wide range of diseases. Among men, the future smoking-attributed disease burden will increase further, highlighting a pressing need for reducing consumption through widespread cessation and uptake prevention.

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.

(1) Background: We investigated the association of four immune-inflammatory markers with clinical features and established location-specific nomograms to predict mortality risk in patients with intracerebral hemorrhage (ICH). (2) Methods: We retrospectively enrolled 613 inpatients with acute ICH. (3) Results: Overall mortality was 22%, which was highest in pontine hemorrhage and lowest in thalamic hemorrhage. All four immune-inflammatory markers exhibited a positive linear correlation with glucose, ICH volume, ICH score, and discharge Modified Rankin Scale (mRS) score. Significant predictors of death due to lobar/putaminal hemorrhage were age, glucose and creatinine levels, initial Glasgow Coma Scale (GCS) score, ICH volume, and presence of intraventricular hemorrhage. None of the immune-inflammatory markers were significant predictors of unfavorable outcome or death. We selected significant factors to establish nomograms for predicting death due to lobar/putaminal, thalamic, pontine, and cerebellar hemorrhages. The C-statistic for predicting death in model I (comprising factors in the establishment of the nomogram) in each type of ICH was higher than that in model II (comprising ICH score alone), except for cerebellar hemorrhage. These nomograms for predicting death had good discrimination (C-index: 0.889 to 0.975) and prediction probabilities (C-index: 0.890 to 0.965). (4) Conclusions: Higher immune-inflammatory markers were associated with larger ICH volume, worse initial GCS, and unfavorable outcomes, but were not independent prognostic predictors. The location-specific nomograms provided novel and accurate models for predicting mortality risk.

Objectives While obstructive sleep apnea (OSA) is associated with several chronic health conditions such as hypertension, obesity, and chronic hypoxia, there is limited information on its association with neuromuscular and spinal pathologies that may be of interest to a musculoskeletal (MSK) medicine or pain management clinician. The objective of this study was to perform a systematic literature review to examine the association between OSA and cervical spine pathologies, postural changes, and pain. Design We systematically reviewed PubMed and Embase databases up to 4/15/2019. We included studies that explored associations between OSA and a) pain, b) postural characteristics or changes, or c) cervical spine morphology. Systematic reviews, meta-analysis, randomized control trials, cohort studies, and case–control studies were included. Case reports, narrative reviews or expert opinion papers were excluded. From the articles that met selection criteria, information regarding type, direction and magnitude of such associations was extracted. The OSA-pain association studies were further divided into 3 subgroups: neuropathic, temporomandibular, and chronic pain. Results 21 articles that met our study criteria were selected for this review. Two studies were on cervical spine pathologies, eight on postural changes, and eleven on pain associated with OSA. Exploring the association between OSA and cervical spine pathologies, postural changes, and pain in this systematic review we found: (1) Cervical spine lesions, fusions, and abnormalities that reduce retropharyngeal space are associated with OSA, likely by way of worsening posture and decreasing range of motion. (2) Head extension and anteriorization are associated with OSA likely as a compensatory mechanism. Extension may improve airway function, while anteriorization helps to maintain visual sense. (3) Head-of-bed-elevation may improve OSA symptoms and can possibly supplement other conservative treatment measures. (4) Neuropathic pain is associated with OSA, likely by way of inflammatory pathways. (5) Oral appliance use (eg mandibular advancement/protruding device) in OSA likely contributes to transient temporomandibular pain. (6) There is little association between OSA and chronic pain prevalence. (7) Increased pain intensity and decreased pain tolerance are somewhat associated with OSA, likely by way of hypoxemia and sleep fragmentation. Conclusions Clinicians in MSK and pain medicine need to consider these associations and consider obtaining imaging studies and/or making referrals for management of their OSA to better provide appropriate care to these patients.

The ankylosed spine is prone to fracture even as a result of minor trauma due to its changed biomechanical properties. Fractures in ankylosing spondylitis (AS) patients are highly unstable and surgical intervention for fixation is warranted. Implant failure rates are high and combined anterior and posterior fixation is required to enhance the fixation outcome. For fusion, anterior interbody fusion or posterior bone graft fusion is often adopted. Here, we introduce a new method which combines vertebroplasty with anterior and posterior approaches to improve pain control, facilitate the long-term fixation outcome and mechanics, and decrease perioperative risks with prompt stabilization, especially in patients with spine curve deformity. Here, we present two AS cases with cervical spine fracture treated with this new method.
