Hip Reconstruction in Nonambulatory Children With Cerebral Palsy: Identifying Risk Factors Associated With Postoperative Complications and Prolonged Length of Stay.

The purpose of this study is to examine the relationship between preoperative comorbidities, surgical complications, and length of stay (LOS) after hip reconstruction in nonambulatory children with cerebral palsy (CP). This single-center retrospective cohort study included 127 patients undergoing hip surgery between 2007 and 2016 who were diagnosed with CP (GMFCS IV/V). The cohort was 54% Gross Motor Function Classification System (GMFCS) V with an average age at surgery of 9 years (range, 3-19 y). Preoperative comorbidities included: presence of a gastrostomy tube, respiratory difficulty requiring positive-pressure ventilation or tracheostomy, history of seizures, and nonverbal status. Complications were dichotomized into major and minor complications according to severity. Multivariable general linear modeling was used to identify factors associated with complications and prolonged LOS. The median LOS in the hospital was 6 days (intequartile range, 5-9 d). The majority of procedures (72%) involved both the femur and acetabulum and 82% of surgeries were performed bilaterally. Patients who experienced a major complication were mostly GMFCS level V and were more likely to spend time in intensive care unit than postanesthetic care unit (P=0.001). Multivariable analysis for a major complication determined that the addition of each comorbid risk fact increased the odds of developing a major complication by 2.6 times (odds ratio, 2.64; 95% confidence interval, 1.56-4.47; P<0.001) regardless of GMFCS level. Multivariable analysis for prolonged LOS determined that major complications (P<0.001), bilaterality (P=0.01), age (P=0.02), female sex (P=0.01), and GMFCS V (P<0.001) were all factors that increased LOS. Migration percentage, acetabular index odds ratio, and pelvic obliquity were not associated with prolonged LOS or the presence of a major complication. From our analysis, the authors found that a patient's premorbid comorbidities were more predictive of the likelihood of sustaining a major complication than their GMFCS level. Identifying high-risk patients preoperatively may help reduce complications and LOS, which ultimately will improve the quality of care the authors deliver to nonambulatory children with CP undergoing hip reconstruction surgery. Level III-retrospective cohort study.

Association Between Arterial Stiffness, Body Mass Index And Cardiorespiratory Fitness In 7-to-17 Years Old Children

Excess adiposity is a risk factor for cardiovascular disease, however, the obesity paradox suggests the existence of a subpopulation of obese individuals that do not suffer from those cardiovascular risks. Cardiorespiratory fitness (CRF) is a strong indicator of cardiovascular health in children and adults. Both obesity and low CRF have shown to independently increase the risk of cardiovascular diseases. PURPOSE: The aim of this study was to investigate how central arterial stiffness is associated with aerobic capacity and body fat percentage and body mass index (BMI) in children aged 7-to-17-years. METHODS: Seventy healthy children, 34 boys and 36 girls (age 7-17 years; BMI 21.5±5.4 kg/m2; fat mass 23.4±11.5%), participated in this study. Percentage of fat mass (FM%) and fat free mass (FFM) were assessed using air displacement plethysmography (Bod Pod COSMED). Arterial stiffness was assessed measuring carotid-femoral PWV (cfPWV) with the SphygmoCor XCEL (AtCor Medical, Inc.). CRF was assessed through breath-by-breath gas analysis (K5, COSMED) using a 15 watts per minute graded exercise test on a cycle ergometer. The VO2 at the first ventilatory threshold (VT1) was identified using the V-slope technique and as the lowest respiratory equivalent for oxygen. Differences in cfPWV between quartiles of VO2 at VT1, %BF, and BMI were assessed using a multivariate general linear model. RESULTS: cfPWV was higher in the first VO2 at VT1 quartile compared to the fourth when VO2 is normalized by FFM (4.99±0.73 vs 4.24±0.69 m/s, p<0.05). No differences in cfPWV were observed between first and fourth VO2 at VT1 quartiles when VO2 is normalized by body mass (5.05±0.92 vs 4.34±0.71 m/s). cfPWV was higher in the fourth and third BMI quartile compared to the first (4.26±0.53 and 4.90±0.66 vs 5.09±0.89, p<0.05) but no differences in cfPWV were observed between fourth, third and first BF% quartiles (5.06±1.04, 4.57±0.54, 4.61±0.64). CONCLUSION: Low central arterial stiffness in children is associated with high CRF expressed as VO2 at VT1, and with low BMI.

Sociocultural factors affecting drive for muscularity among male college students in Malaysia

Compared with females, little research on muscularity and the sociocultural influences on this domain has been conducted with males in non-Western societies. The current study explored these sociocultural predictors of drive for muscularity among Malaysian male college students, specifically in terms of ethnicity and exposure to media (i.e., Internet and social media). In total, 166 male college students from two universities in Kuala Lumpur were asked to rate the questionnaires as to muscularity-oriented attitudes and behaviours. Multivariable general linear model analyses revealed that being Chinese was a strong predictor of muscularity-oriented attitudes and behaviours. In addition, modern media, particularly, Internet use and the number of followers on Instagram, was found to significantly predict males' drive for muscularity. Overall findings suggest that males of particular ethnic groups may be at higher risk for negative body image compared to the other ethnic populations and modern media use may accelerate drive for muscularity, which may also in turn place males at higher risk for excess muscularity-oriented thoughts and behaviours.

Trends in utilization, conversion rates, and outcomes for minimally invasive approaches to non-metastatic rectal cancer: a national cancer database analysis.

This studyexaminedutilization and conversion rates for robotic and laparoscopic approaches to non-metastatic rectal cancer. Secondary aims were to examine short- and long-term outcomes of patients who underwent conversion to laparotomy from each approach. The National Cancer Database (NCDB) was reviewed for all casesof non-metastatic adenocarcinoma of the rectum or rectosigmoid junction who underwent surgical resection from 2010 to 2016. Utilization rates of robotic, laparoscopic, and open approacheswere examined. Patients were split into cohorts byapproach. Subgroup analyses were performed by primary tumor site and surgical procedure. Multivariable analysis was performed by multivariable logistic regression for binary outcomes and multivariable general linear models for continuous outcomes. Survival analysis was performed byKaplan-Meier and multivariable cox-proportional hazards regression. From 2010 to 2016,there was a statistically significant increase in utilization of the robotic and laparoscopic approaches over the study period and a statistically significant decrease in utilization of the open approach. The conversion rates for robotic and laparoscopic cohorts were 7.0% and 15.7%, p < 0.0001. Subgroup analysisrevealed statistically lower conversion rates between robotic and laparoscopic approaches for rectosigmoid and rectal tumors and for LAR and APR. Converted cohorts hadstatistically significant higher odds of short term mortality than thenon-converted cohorts (p < 0.05).Laparoscopic conversion had statistically higher odds of positive margins (p < 0.0001) and 30-day unplanned readmission (p < 0.0001) than the laparoscopic non-conversion. Increased adjusted mortality hazard was seen for converted laparoscopy relative to non-converted laparoscopy (p = 0.0019). From 2010 to 2016, there was a significant increase in utilization of minimally invasive approaches to surgical management of non-metastatic rectal cancer. A robotic approach demonstrated decreased conversion ratesthan a laparoscopic approach at the rectosigmoid junction and rectum and for LAR and APR. Improved outcomes were seen in the minimally invasive cohorts compared to those that converted to laparotomy.

Workplace resources, mentorship, and burnout in early career physician-scientists: a cross sectional study in Japan

BackgroundPhysician-scientists are a vital segment of the healthcare workforce, but they may face significant challenges balancing and integrating clinical responsibilities, scientific research, and domestic responsibilities. This study investigates factors associated with burnout among highly successful early career physician-researchers in Japan.MethodAmong 1790 physician awardees of Grant-in-Aid for Young Scientists by the Japanese Ministry in 2014–2015, 490 participated in this cross-sectional survey in 2016 (usable response rate 23.8%). The primary outcome was psychological burnout, measured by the Copenhagen Burnout Inventory (i.e., personal burnout, work-related burnout, and patient-related burnout). “Workplace resources” in our study refers to the presence of career education in the workplace, promotion of gender equity, well-being consultation services on “career and work,” “research,” “harassment,” and/or “mental health,” as well as the presence of a role model in the workplace who has perceived good work-life balance.ResultsAmong 408 physician-researchers (75% male, mean age 37 yrs), personal burnout scores were slightly higher in women than in men (mean score, 41.9 points vs. 36.7 points, difference, 5.2, 95% confidence interval, 0.5–9.9, p = 0.029), but work-related and patient-related burnout scores did not differ significantly between genders. Over half of women (64%) and men (58%) had a mentor (p = 0.374). In multivariable general linear regression models, personal burnout scores were higher for women (β = 4.98, p = 0.045), and lower among those who had a mentor (β = − 5.82, p = 0.010) and whose workplaces had well-being consultation services (β = − 0.79, p = 0.022). Work-related burnout scores were lower among those with larger amounts of grant funding (β = − 4.70, p = 0.013), a mentor (β = − 6.12, p = 0.002), well-being consultation services (β = − 0.78, p = 0.008) and a role model with a perceived good work-life balance (β = − 4.00, p = 0.038). Patient-related burnout scores were higher among physician-scientists aged older than 37 years (β = 6.25, p = 0.002) and those who had board certification (β = 9.01, p = 0.017), while these scores were lower among those had larger amounts of funding (β = − 5.01, p = 0.006) or a mentor (β = − 5.35, p = 0.006).ConclusionsWorkplace resources and mentorship appear to be associated with lower levels of psychological burnout for both men and women early career physician-scientists.

Urinary Concentrations of Phthalate Metabolite Mixtures in Relation to Serum Biomarkers of Thyroid Function and Autoimmunity among Women from a Fertility Center.

Background:Although previous epidemiological studies have explored associations of phthalate metabolites with thyroid function, no studies to date have assessed associations of mixtures with thyroid function and autoimmunity among potentially susceptible subgroups such as subfertile women.Objective:We aimed to explore associations of mixtures of urinary phthalate metabolites with serum markers of thyroid function and autoimmunity.Methods:This cross-sectional study included 558 women attending a fertility center who provided one spot urine and one blood sample at enrollment (2005–2015). We quantified urinary concentrations of eight phthalate metabolites using mass spectrometry, and biomarkers of thyroid function [thyroid-stimulating hormone (TSH), free and total thyroxine (, ) and triiodothyronine (, ), and autoimmunity [thyroid peroxidase and thyroglobulin antibodies (TPOAb and TgAb, respectively)] in serum using electrochemiluminescence assays. We applied principal component analysis (PCA) and Bayesian kernel machine regression (BKMR) to identify the main patterns of urinary phthalate metabolites. We used linear mixed models to assess the association between PCA-derived factor scores in quintiles and serum thyroid function and autoimmunity, adjusting for age, body mass index (BMI), specific gravity (SG), and, for the PCA, other factor scores.Results:We observed two factors using PCA, one representing the di(2-ethylhexyl) (DEHP) and another non-DEHP metabolites. Compared to women in the lowest quintile of the DEHP factor scores, women in the highest quintile had significantly lower serum concentrations of , , , and [absolute difference: ; 95% confidence interval (CI): , ; ; absolute difference: ; 95% CI: , ; ; absolute difference: ; 95% CI: 0.54, ; ; and absolute difference: ; 95% CI: , ; , respectively]. Using BKMR, we observed that mono(2-ethyl-5-hydroxyhexyl) phthalate (MEHHP) was the primary contributor to these negative associations. DEHP and non-DEHP factor scores were not associated with serum TSH, TgAb, or TPOAb.Conclusions:Mixtures of urinary DEHP metabolites were inversely associated with serum biomarkers of thyroid function but not with autoimmunity, which were within normal ranges for healthy adult women. https://doi.org/10.1289/EHP6740

Health Promoting Lifestyle and its Relationship with Self-Efficacy in Iranian Mastectomized Women.

Introduction:Lifestyle modification has an important role in long-term health of breast cancer patients. As a result, this study aimed to identify the health-promoting lifestyle and its subdomains in mastectomized women and its relationship with self-efficacy. Materials and Methods:This cross-sectional study investigated 100 mastectomized women in Tabriz-Iran, 2018. The participants were selected using the convenience sampling method. Data was collected using a sociodemographic questionnaire, the Health Promoting Lifestyle Profile II (HPLP-II), and the General Self-Efficacy Scale by Sherer. The multivariate general linear model with adjusting the sociodemographic variables was used to determine the relationship of the health-promoting lifestyle with self-efficacy. Results:The mean±SD total score of the health-promoting behaviors was 135.5±16.7 from the obtainable score of 52 to 208. The highest and lowest mean scores were observed in the spiritual growth (25.4±4.3) and physical activity (15.2±4.4), respectively. The mean±SD self-efficacy score in this study was 57.3±7.4 from the obtainable score of 17 to 85. There was a significant positive correlation between the total score of the health-promoting lifestyle (r= 0.369; p<0.001) with self-efficacy. Results from the adjusted general linear model showed that the age, educational attainment of the spouse, and self-efficacy were the health-promoting lifestyle predictors. Conclusion:The findings of this study indicate the importance of self-efficacy and modifiable variables such as education in the engagement of mastectomized women in the health-promoting lifestyle. Regarding the positive relationship of self-efficacy with the health-promoting lifestyle, it seems that the interventional attempts to improve self-efficacy in these patients especially with considering the variables of age and spouse’s educational level can contribute to the improvement of the health-promoting lifestyle.

Community Susceptibility and Resiliency to COVID-19 Across the Rural-Urban Continuum in the United States.

PurposeThis study creates a COVID‐19 susceptibility scale at the county level, describes its components, and then assesses the health and socioeconomic resiliency of susceptible places across the rural‐urban continuum.MethodsFactor analysis grouped 11 indicators into 7 distinct susceptibility factors for 3,079 counties in the conterminous United States. Unconditional mean differences are assessed using a multivariate general linear model. Data from 2018 are primarily taken from the US Census Bureau and CDC.ResultsAbout 33% of rural counties are highly susceptible to COVID‐19, driven by older and health‐compromised populations, and care facilities for the elderly. Major vulnerabilities in rural counties include fewer physicians, lack of mental health services, higher disability, and more uninsured. Poor Internet access limits telemedicine. Lack of social capital and social services may hinder local pandemic recovery. Meat processing facilities drive risk in micropolitan counties. Although metropolitan counties are less susceptible due to healthier and younger populations, about 6% are at risk due to community spread from dense populations. Metropolitan vulnerabilities include minorities at higher health and diabetes risk, language barriers, being a transportation hub that helps spread infection, and acute housing distress.ConclusionsThere is an immediate need to know specific types of susceptibilities and vulnerabilities ahead of time to allow local and state health officials to plan and allocate resources accordingly. In rural areas it is essential to shelter‐in‐place vulnerable populations, whereas in large metropolitan areas general closure orders are needed to stop community spread. Pandemic response plans should address vulnerabilities.

1059 Sleep Parameters In People With Type 2 Diabetes With And Without Insomnia Symptoms

Abstract Introduction There is an increasing awareness of the high prevalence of insomnia symptoms in people with type 2 diabetes (T2D). Past studies have demonstrated the importance of measuring sleep parameters in both averages and variabilities using subjective and objective methods. Thus, we aimed to compare the averages and variability of sleep parameters in people with T2D with and without insomnia symptoms. Methods Actigraph measurements and sleep diaries were used in 59 participants to assess sleep parameters, including sleep efficiency (SE), sleep latency, total sleep time, and wake after sleep onset over seven nights. Validated instruments were used to assess the symptoms of depression, anxiety, and pain. Circular data were used to describe the distribution of bed distribution with SE as a magnitude for both groups. Mann Whitney U test was utilized to compare averages and variability of sleep parameters between the two groups. Multivariable general linear model to control for demographic and clinical variables. For the secondary aim, multiple linear regression tests were utilized to assess the association between averages and variability values for both groups. Results SE was found to be lower in average and higher in variability for participants with T2D and insomnia symptoms, than those with T2D only subjectively and objectively. SE variability was also the only sleep parameter higher in people with T2D and insomnia symptoms, with psychological symptoms potentially playing a role in this difference. We observed that people in T2D+Insomnia tend to go to bed earlier compared to the T2D only group based on objective measures, but no difference was observed between groups in subjective measures. The only significant relationship in both objective and subjective measures was between the averages and variability of SE. Conclusion Our findings suggest a discrepancy between subjective and objective measures in only average of total sleep time, as well as agreement in measures of variability in sleep parameters. Also, the relationship between averages and variabilities suggested the importance of improving SE to minimize its variability. Further research is warranted to investigate the complex relationship between sleep parameters and psychological factors in people with T2D and insomnia symptoms. Support None

Relationship between HIF-1 and Circadian Clock Proteins in Obstructive Sleep Apnea Patients-Preliminary Study.

Obstructive sleep apnea (OSA) is characterized by intermittent hypoxia and associated with the disruption of circadian rhythm. The study aimed to assess the relationship between hypoxia-inducible factor (HIF) subunits, circadian clock proteins, and polysomnography (PSG) variables, in healthy individuals and severe OSA patients. The study included 20 individuals, who underwent PSG and were divided into severe OSA group (n = 10; AHI ≥ 30) and healthy control (n = 10; AHI < 5) based on apnea-hypopnea index (AHI). All participants had their peripheral blood collected in the evening before and the morning after the PSG. HIF-1α, HIF-1β, BMAL1, CLOCK, CRY1, and PER1 protein concertation measurements were performed using ELISA. In a multivariate general linear model with the concentration of all circadian clock proteins as dependent variables, evening HIF-1α protein level was the only significant covariant (p = 0.025). Corrected models were significant for morning and evening PER1 (p = 0.008 and p = 0.006, respectively), evening (p = 0.043), and evening BMAL protein level (p = 0.046). In corrected models, evening HIF-1α protein level had an influence only on the evening PER1 protein level. Results suggest that OSA patients are at risk for developing circadian clock disruption. This process might be mediated by subunit α of HIF-1, as its increased protein level is associated with overexpression of circadian clock proteins.

S74. AEROBIC EXERCISE AND COGNITIVE REMEDIATION IN MULTIEPISODE SCHIZOPHRENIA AND SCHIZOAFFECTIVE DISORDER: PRELIMINARY RESULTS: FROM A RANDOMIZED CLINICAL TRIAL

BackgroundCognitive remediation (CR) is an evidence-based behavioral intervention for cognitive impairment in schizophrenia. Although the effectiveness of CR is well stablished, its effects are modest, especially in terms of functional outcome. There is an emerging literature suggesting that adding aerobic exercise to CR may exert synergistic effects. Despite these promising reports, the extent to which aerobic exercise in combination with CRT can improve cognitive and daily functioning in multiepisode schizophrenia and schizoaffective disorder remains unclear.MethodsThis is a single-blinded, randomized clinical trial (NCT02864576) with two different groups: 1) patients with multiepisode schizophrenia or schizoaffective disorder receiving 3-month Aerobic exercise plus CR treatment (three weekly sessions, 40min of Aerobic exercise and 90min of CR), and 2) patients with multiepisode schizophrenia or schizoaffective disorder receiving Healthy lifestyle promotion plus CR treatment (three weekly sessions, 40min of Healthy lifestyle promotion and 90min of CR). Primary outcome measures were the MATRICS Consensus Cognitive Battery (MCCB) and the Global Assessment of Functioning (GAF), which were assessed (among others) at baseline and immediately after treatment. For the present work, the sample included in the analysis were 34 patients for whom cognitive data were available. Treatment effects on neurocognition and functional outcome were analyzed by applying the multivariate general linear model (GLM) repeated measures.ResultsAfter treatment, both groups exhibited a significant improvement in MCCB visual learning memory (F=14.298, p= 0.001), working memory (F=6.626, p= 0.015) and speed of processing (F=16.344, p= 0.001) domains. However, no significant benefits were evidenced for problem solving (F=2.143, p= 0.153), verbal learning memory (F= 0.321, p= 0.575) and attention/vigilance (F=0.740, p= 0.397) domains. Functional outcome, as measured by the GAF, was more improved in the Aerobic exercise plus CR group than in the Healthy lifestyle promotion plus CR group (F=4.248, p= 0.047).DiscussionOur preliminary findings indicate that combining aerobic exercise with cognitive remediation may promote a large impact on functional outcome in patients with multiepisode schizophrenia or schizoaffective disorder.

Associations between early childhood caries, malnutrition and anemia: a global perspective

BackgroundMalnutrition is the main risk factor for most common communicable diseases. The aim of this study is to determine the relationship between country-level prevalence of early childhood caries (ECC), malnutrition and anemia in infants and preschool children.MethodsMatched country-level ECC, malnutrition and anemia prevalence were generated from databases covering the period 2000 to 2017. Multivariate general linear models were developed to assess the relationship between outcome variables (prevalence of stunting, wasting, overweight, and anemia) and the explanatory variable (ECC prevalence) adjusted for gross national income per capita. Adjusted regression coefficients (B) and partial eta squared were computed.ResultsThe mean (standard deviation (SD)) ECC prevalence was 23.8 (14.8)% for 0–2 year-olds and 57.3 (22.4)% for 3–5-year-olds. The mean (SD) prevalence of wasting was 6.3 (4.8)%, overweight 7.2 (4.9)%, stunting 24.3 (13.5)%, and anemia 37.8 (18.1)%. For 0–2-year-olds, the strongest and only significant association was between the prevalence of ECC and overweight (η2 = 0.21): 1 % higher ECC prevalence was associated with 0.12% higher prevalence of overweight (B = 0.12, P = 0.03). In 3–5-year-olds, the strongest and only significant association was between the prevalence of ECC and anemia (η2 = 0.08): 1 % higher prevalence of ECC was associated with 0.14% lower prevalence of anemia (B = − 0.14, P = 0.048).ConclusionCountry-level prevalence of ECC was associated with malnutrition in 0–2-year-olds and with anemia in 3–5-year-olds. The pathway for the direct relationship between ECC and overweight may be diet related. The pathway for the inverse relationship between ECC and anemia is less clear and needs further investigations.

Comorbid Conditions and Health-Related Quality of Life in Ambulatory Heart Failure Patients: REVIVAL (Registry Evaluation of Vital Information for VADs in Ambulatory Life REVIVAL).

Patients with heart failure (HF) often have multiple chronic conditions that may impact health-related quality of life (HRQOL) despite HF therapy. We sought to determine the association between noncardiac comorbidities and HRQOL in ambulatory patients with advanced HF. Baseline data from 373 subjects in REVIVAL (Registry Evaluation of Vital Information for Ventricular Assist Devices in Ambulatory Life) were analyzed using multivariable general linear models to evaluate the relationship between comorbidities and HRQOL (EuroQol Visual Analogue Scale, EQ-5D-3L Index Score, and Kansas City Cardiomyopathy Questionnaire). The primary independent variables were a comorbidity index (sum of 14 noncardiac conditions), a residual comorbidity index (without depression), and depression alone. The median (25th to 75th percentile) number of comorbidities was 3 (2-4). Increasing comorbidity burden was associated with a reduction in generic (EQ-5D Index, P=0.005) and HF-specific (Kansas City Cardiomyopathy Questionnaire, P=0.001) HRQOL. The residual comorbidity index was not associated with HRQOL when depression included in the model independently, while depression was associated with HRQOL across all measures. Participants with depression (versus without) scored on average 13 points (95% CI, 8-17) lower on the EuroQol Visual Analogue Scale, 0.15 points (95% CI, 0.12-0.18) lower on the EQ-5D Index, and 24.9 points (95% CI, 21.2-28.5) lower on the Kansas City Cardiomyopathy Questionnaire overall summary score. While noncardiac comorbidities were prevalent in ambulatory advanced HF patients, only depression was associated with decreased generic and HF-specific HRQOL. Other than depression, the presence of noncardiac comorbidities should not impact expected gains in HRQOL following ventricular assist device implantation, provided the conditions are not a contraindication to implant.

Serum chemerin and visfatin levels and their ratio as possible diagnostic parameters of rheumatoid arthritis.

ObjectivesRheumatoid arthritis (RA) is a chronic inflammatory disease affecting the synovium and articular cartilage that initiates joint damage. Rheumatoid arthritis is associated with a change in many inflammatory biomarkers. The present study aims to examine the diagnostic ability of inflammatory adipocytokines (chemerin and visfatin) and their ratio for RA disease.Material and methodsThe study recruited 60 RA patients and 30 healthy controls. Serum visfatin and chemerin were measured using the ELISA technique. Some related parameters including body mass index (BMI), lipid profile components, C-reactive protein (CRP), and uric acid levels were also determined and correlated with the level of these adipokines.ResultsSerum chemerin, visfatin, CRP, and uric acid (UA) levels were significantly higher (p< 0.05) in RA patients than those of the control group. The multivariate general linear model (GLM) analysis showed that 70.7% of the change in the level of measured parameters can be explained by the presence of RA disease (partial η2 = 0.707, p< 0.001). To explore which parameter was affected by the diagnosis, the results of tests between subjects showed that all biomarkers were affected significantly by the diagnosis and the greater effects were on CRP (partial η2 = 0.480, p< 0.001) followed by chemerin (partial η2 = 0.295, p< 0.001), while visfatinshowed partial η2 = 0.079 only. Chemerin showed the highest sensitivity (88.1%) and specificity (75.9%) for diagnosis of RA at cut-off concentration = 187.88 ng/ml as compared with other parameters.ConclusionsChemerin and visfatin levels are affected by RA disease when adjusted for other cofounders. The present results suggest that serum chemerin can be used as an inflammatory marker of RA patients as it has good sensitivity and specificity.

Vitamin D Status and Related Factors among Korean Stroke Survivors: A Nationwide Population-Based Study.

The aim of this study was to investigate the vitamin D status and related factors in community-dwelling Korean stroke survivors. Data of 23,872 individuals ≥20 y who participated in the Korea National Health and Nutrition Examination Surveys (KNHANES) were analyzed. Participants who had ever been diagnosed with stroke by a doctor were defined as stroke survivors (n=431). The serum 25-hydroxyvitamin D (25(OH)D) level was measured by radioimmunoassay, and vitamin D deficiency was defined as 25(OH)D<20 ng/mL. The association between vitamin D and stroke status was analyzed using multivariable general linear models and logistic regression models adjusted for sociodemographic and clinical covariates. The adjusted mean 25(OH)D level of stroke survivors was significantly lower than that of nonstroke controls; however, after adjustment for systolic blood pressure level and use of antihypertensive medication, the difference was no longer statistically significant. The burden of 25(OH)D deficiency was not higher in stroke survivors than in nonstroke controls (adjusted OR=1.14; 95% CI, 0.81-1.62). Current smoking was independently associated with 25(OH)D deficiency among stroke survivors (adjusted OR=3.17; 95% CI, 1.33-7.55). These findings indicated that treatment of high blood pressure and smoking cessation may be important measures to control vitamin D levels in stroke survivors.

A global real-world assessment of the impact on health-related quality of life and work productivity of migraine in patients with insufficient versus good response to triptan medication

BackgroundMigraine is a chronic, disabling neurological disease characterized by moderate-to-severe headache pain with other symptoms, including nausea, vomiting, and photophobia. Triptans, while generally effective, are insufficiently efficacious in 30–40% of patients and poorly tolerated by or contraindicated in others. We assessed the impact of insufficient response to triptans on health-related quality of life (HRQoL) and work productivity in patients currently receiving any prescribed triptan formulation as their only acute migraine medication.MethodsData were from the 2017 Adelphi Migraine Disease Specific Programme, a cross-sectional survey of primary care physicians, neurologists, and headache specialists and their consulting patients with migraine in the USA, France, Germany, Italy, Spain, and UK. Triptan insufficient responders (TIRs) achieved freedom from headache pain within 2 h of acute treatment in ≤3/5 migraine attacks; triptan responders (TRs) achieved pain freedom within 2 h in ≥4/5 attacks. Multivariable general linear model examined differences between TIRs and TRs in HRQoL and work productivity. Logistic regression identified factors associated with insufficient response to triptans.ResultsThe study included 1413 triptan-treated patients (TIRs: n = 483, 34.2%; TRs: n = 930, 65.8%). TIRs were more likely to be female (76% vs. 70% for TIRs vs TRs, respectively; p = 0.011), older (mean age 42.6 vs. 40.5 years; p = 0.003), and had more headache days/month (7.0 vs. 4.4; p < 0.001). TIRs had significantly more disability, with higher Migraine Disability Scores (MIDAS; 13.2 vs. 7.7; p < 0.001), lower Migraine-specific Quality of Life scores, indicating greater impact (Role Function Restrictive: 62.4 vs. 74.5; Role Function Preventive: 70.0 vs. 82.2; Emotional Function: 67.7 vs. 82.1; all p < 0.001), and lower EQ5D utility scores (0.84 vs. 0.91; p = 0.001). Work productivity and activity were impaired (absenteeism, 8.6% vs. 5.1% for TIRs vs. TRs; presenteeism, 34.3% vs. 21.0%; work impairment, 37.1% vs. 23.3%; overall activity impairment, 39.8% vs. 25.3%; all p < 0.05).ConclusionHRQoL and work productivity were significantly impacted in TIRs versus TRs in this real-world analysis of patients with migraine acutely treated with triptans, highlighting the need for more effective treatments for patients with an insufficient triptan response. Further research is needed to establish causal relationships between insufficient response and these outcomes.

Meta-analysis of Technology-Enabled Mindfulness-Based Programs for Negative Affect and Mindful Awareness

Existing meta-analyses of mindfulness-based programs (MBPs) suggest inconsistent effects, and few focus on technology-enabled MBPs. Technology-enabled MBPs are programs delivered via the Internet in web apps, which are accessed through Internet browsers, or native apps, which are applications installed directly on smart mobile devices. This meta-analysis provides an updated synthesis of technology-enabled MBPs’ effects on negative affect and mindfulness and discusses the role of moderators in these effects. A search was conducted through August 2019 of databases PubMed, Ovid MEDLINE, PsychINFO, and the website MINDFULNET.org for original randomized clinical trials focused on technology-enabled MBPs. Additional inclusion criteria included English language publications and outcome measures of negative affect and/or measures of mindful awareness. A medium effect was observed of technology-enabled MBPs on stress (Hedges g = − 0.47, 95% CI − 1.02 to 0.21, p < 0.01). Small effects were observed on symptoms of anxiety (Hedges g = − 0.21, 95% CI − 0.39 to − 0.03, p = 0.02) and depression (Hedges g = − 0.25, 95% CI − 0.37 to − 0.12, p < 0.01) as well as mindful awareness (g = 0.4, 95% CI 0.54 to 0.07, p < 0.01). Multivariate regressions and general linear models revealed that intervention duration, percentage of women participants, human-supported interventions, and type of control condition contributed significantly to effect size variability. Technology-enabled MBPs included in this analysis demonstrated small to medium effects on outcomes of negative affect and mindfulness. Variability in study outcomes appears to be related to experimental and intervention characteristics.

Residual thoracolumbar/lumbar curve is related to self-image after posterior spinal fusion for Lenke 1 and 2 curves in adolescent idiopathic scoliosis patients.

Although it is well known that major curve severity in adolescent idiopathic scoliosis (AIS) is inversely related to self-image, surgeons often encounter patients who complain of low self-image with preoperatively mild curves or postoperatively well-corrected main curves, suggesting the presence of other factors. This study examined factors contributing to self-image in AIS. A total of 86 consecutive patients who underwent posterior spinal fusion for AIS Lenke 1 or 2 curves and were followed for a minimum of 2 years were included in this study of patient self-image based on data that included scores reported on the Scoliosis Research Society survey (SRS-22r). The authors evaluated sex, BMI, Risser grade, age, angle of trunk rotation, Cobb angle of the main thoracic (MT) curve, Cobb angle of the thoracolumbar/lumbar (TL/L) curve, apical vertebral translation (AVT), T5-12 kyphotic angle, and clavicular angle. Univariate and multivariate general linear models were employed to identify preoperative and 2-year postoperative factors that impact self-image. Univariate analysis revealed no significant correlation between preoperative MT curve Cobb angle and SRS-22r self-image score (p = 0.51), although patients with a higher MT curve AVT had a significantly worse preoperative self-image (p < 0.01). Two years postoperatively, larger Cobb angle of the TL/L curve (p = 0.01) and higher Risser grade (p = 0.03) resulted in significantly lower self-image scores. In multivariate testing, preoperative MT curve AVT remained significantly related to diminished self-image (p < 0.01). Two years later, higher TL/L curve (p < 0.01), Risser grade (p = 0.03), and MT curve AVT (p = 0.03) had significant associations with lower self-image scores. Preoperative MT curve AVT appears more strongly related to self-image than does Cobb angle. Two years postoperatively, persistent TL/L region curvature and high Risser grade may also be associated with diminished patient self-image.

Factors associated with subjective cognitive function in epilepsy and psychogenic non-epileptic seizures

ObjectiveTo identify factors associated with subjective cognitive complaints in people with presumed seizure disorders referred for video electroencephalogram monitoring (VEM). MethodsAdult patients admitted for inpatient VEM were recruited. Objective cognitive function was measured with the Neuropsychiatry Unit Cognitive Screening Tool, subjective cognitive function with the Quality of Life in Epilepsy Inventory-89 subscales, and anxiety and depressive symptoms with the Hospital Anxiety and Depression Scale. Multivariate Bayesian general linear models were used to identify predictors of subjective cognitive function. Results331 patients met inclusion criteria. Mean age was 39.3 years and 61.9 % patients were female. Diagnoses included epilepsy, psychogenic non-epileptic seizures (PNES) or both conditions. Depression, anxiety and objective cognitive function were predictors of subjective cognitive function across all domains. Depression was the strongest predictor of subjective memory and attention, whilst objective cognition was the strongest predictor of subjective language function. Mood also mediated the relationship between objective function and subjective function across all domains to varying extents; depression exerted the strongest effect of 22 % for the memory domain; conversely, language domain was least influenced by mood, with depression mediating 11 % and anxiety mediating only 9% of the subjective-objective relationship. SignificanceMood and objective cognitive function are both important contributors to subjective cognitive function for patients undergoing VEM. Clinicians should consider referring patients with cognitive complaints for both neurocognitive workup and neuropsychiatric evaluation. Future work may examine the effects of treating concomitant mood disorders on subjective cognitive function.

Factors associated with provision of smoking cessation support to pregnant women \u2013 a cross-sectional survey of midwives in New South Wales, Australia

BackgroundSmoking is the most important preventable cause of adverse pregnancy outcomes, but provision of smoking cessation support (SCS) to pregnant women is poor. We examined the association between midwives’ implementation of SCS (5As – Ask, Advise, Assess, Assist, Arrange follow-up) and reported barriers/enablers to implementation.MethodsOn-line anonymous survey of midwives providing antenatal care in New South Wales (NSW), Australia, assessing provision of the 5As and barriers/enablers to their implementation, using the Theoretical Domains Framework (TDF). Factor analyses identified constructs underlying the 5As; and barriers/enablers. Multivariate general linear models examined relationships between the barrier/enabler factors and the 5As factors.ResultsOf 750 midwives invited, 150 (20%) participated. Respondents more commonly reported Asking and Assessing than Advising, Assisting, or Arranging follow-up (e.g. 77% always Ask smoking status; 17% always Arrange follow-up). Three 5As factors were identified– ‘Helping’, ‘Assessing quitting’ and ‘Assessing dependence’. Responses to barrier/enabler items showed greater knowledge, skills, intentions, and confidence with Assessment than Assisting; endorsement for SCS as a priority and part of midwives’ professional role; and gaps in training and organisational support for SCS. Nine barrier/enabler factors were identified. Of these, the factors of ‘Capability’ (knowledge, skills, confidence); ‘Work Environment’ (service has resources, capacity, champions and values SCS) and ‘Personal priority’ (part of role and a priority) predicted ‘Helping’.ConclusionThe TDF enabled systematic identification of barriers to providing SCS, and the multivariate models identified key contributors to poor implementation. Combined with qualitative data, these results have been mapped to intervention components to develop a comprehensive intervention to improve SCS.
