Loneliness and Crowded Living Predicted Poor Health in a Sample of Cancer Patients During COVID-19 Pandemic.

We investigated the influence of social determinants of health (SDOH), healthcare services, and health behaviors on mental and physical health outcomes of cancer patients between the first winter and the following post-vaccine summer of the COVID-19 pandemic. A three-wave online survey of individuals diagnosed with incident cancer between January 2019 and January 2020 was conducted between November of 2020 and August of 2021 in northeast Ohio. Descriptive analysis and mixed-effect regression analyses were performed. A total of 322 newly diagnosed cancer patients, with 40 African Americans and 282 Whites (215 from metropolitan areas and 67 nonmetropolitan) responded to the survey questions. In Wave 3 ending in August 2021, the survey respondents reported significantly reduced depression (p = .019) on the Hamilton Depression Rating Scale and improved global health (p = .036) on PROMIS. With age, comorbidity, and other demographic and medical variables controlled in the analyses, the feeling of loneliness (p < .001) and crowded living space (p = .001, p = .015) were the two most prominent factors associated with depression, irritability, and poor global health at baseline, with the lowest p values and persistent effect. Self-efficacy of taking preventive measures was associated with reduced depression (p = .001) and improved global health (p = .029). Increasing access to medicine (p < .01) and satisfaction with telehealth appointments (p < .01) were significantly associated with better global health and reduced irritability. Respondents who had private health insurance reported better health than those that had Medicare coverage only (p < .05). This longitudinal, observational study demonstrated the impact of SDOH on health outcomes of cancer patients. Substandard living conditions resulting in loneliness and crowdedness, quality of medical care (e.g., quality telehealth and access to medicine), and personal behaviors (e.g., self-efficacy) were significantly associated with health outcomes in newly diagnosed cancer patients during the pandemic and should be given adequate consideration for the purpose of improving clinical care.

Effect of Dietary Choline Consumption on the Development of Urinary Urgency Incontinence in a Longitudinal Cohort of Women.

INTRODUCTION AND HYPOTHESIS: The objective of this study was to determine whether differences in the cumulative dietary intake of choline, is associated with the risk of developing urge urinary incontinence (UUI). METHODS: This was an analysis within the Nurses' Health Study (NHS) I and II. The main exposure was the cumulative daily intake for each choline-containing compound obtained from a detailed daily food frequency questionnaire. The primary outcome was UUI, defined as urine loss with a sudden feeling of bladder fullness or when a toilet is inaccessible, occurring >1/month. Cox proportional hazards regression models were used to calculate multivariate-adjusted relative risks and 95% confidence intervals (CIs) for the association between total choline and choline derivatives and risk of UUI. Fixed effects meta-analyses of results from NHSI and NHSII were performed for postmenopausal women only to obtain a pooled estimate of the impact of choline consumption on UUI. RESULTS: There were 33,273 participants in NHSI and 38,732 in NHSII who met all the criteria for inclusion in the analysis. The incidence of UUI was 9.41% (n=3,139) in NHSI and 4.25% (n=1,646) in NHSII. After adjusting for confounders choline was not found to be associated with UUI in postmenopausal women. However, in premenopausal women, relative to the lowest quartile, the highest quartile of consumption of total choline (aRR = 0.79, 95% CI: 0.64-0.99), free choline (aRR = 0.74, 95% CI: 0.58-0.94), and phosphocholine (aRR = 0.77, 95% CI: 0.61-0.96) were associated with a reduced risk of UUI. CONCLUSIONS: Increased dietary choline consumption was associated with a reduced risk of UUI among premenopausal women.

Baseline situational analysis in Bangladesh, Jordan, Paraguay, the Philippines, Ukraine, and Zimbabwe for the WHO Special Initiative for Mental Health: Universal Health Coverage for Mental Health.

INTRODUCTION: Mental, neurological and substance use conditions lead to tremendous suffering, yet globally access to effective care is limited. In line with the 13th General Programme of Work (GPW 13), in 2019 the World Health Organization (WHO) launched the WHO Special Initiative for Mental Health: Universal Health Coverage for Mental Health to advance mental health policies, advocacy, and human rights and to scale up access to quality and affordable care for people living with mental health conditions. Six countries were selected as 'early-adopter' countries for the WHO Special Initiative for Mental Health in the initial phase. Our objective was to rapidly and comprehensively assess the strength of mental health systems in each country with the goal of informing national priority-setting at the outset of the Initiative. METHODS: We used a modified version of the Program for Improving Mental Health Care (PRIME) situational analysis tool. We used a participatory process to document national demographic and population health characteristics; environmental, sociopolitical, and health-related threats; the status of mental health policies and plans; the prevalence of mental disorders and treatment coverage; and the availability of resources for mental health. RESULTS: Each country had distinct needs, though several common themes emerged. Most were dealing with crises with serious implications for population mental health. None had sufficient mental health services to meet their needs. All aimed to decentralize and deinstitutionalize mental health services, to integrate mental health care into primary health care, and to devote more financial and human resources to mental health systems. All cited insufficient and inequitably distributed specialist human resources for mental health as a major impediment. CONCLUSIONS: This rapid assessment facilitated priority-setting for mental health system strengthening by national stakeholders. Next steps include convening design workshops in each country and initiating monitoring and evaluation procedures.

A survey of cancer patients, caregivers, and providers regarding familiarity, importance, and utilization of supportive and integrative oncology services.

PURPOSE: Supportive and integrative oncology services aim to improve the quality of life of cancer patients. This study characterizes the views of these services among cancer patients, caregivers, and providers at a comprehensive cancer center. METHODS: A cross-sectional survey was administered in 2017-2018. The survey asked about participants' familiarity, perceived importance, use, accessibility, and barriers to 19 supportive and integrative oncology services using a Likert scale. Data were analyzed using the Kruskal-Wallis test and a proportional odds regression model. RESULTS: A total of 976 surveys were obtained (604 patient surveys, 199 caregiver surveys, 173 provider surveys). Patients were mostly female (56.3%), ≥60 years old (59.4%), and Caucasian (66%). Providers were an even distribution of nurses, physicians, and advanced practice providers. Patients felt social work and nutrition services were the most familiar (36.4% and 34.8%) and the most important (46.3% and 54.5%). Caregivers were also most familiar with those two services, but felt that nutrition and learning resources were most important. Social work and nutrition were easiest to access and used the most by both patients and providers. There was a positive correlation between accessibility and perceived importance. Being unaware was the most common barrier identified by patients (38.4%), providers (67.1%), and caregivers (33.7%). CONCLUSION: Social work and nutrition services were most familiar to respondents, and also generally the most important, accessible, and utilized. Lack of awareness was the most common barrier cited and suggests that increased efforts to educate patients and providers about other services available are needed.

Interest and Willingness to Pay for Integrative Therapies of Patients With Cancer and Caregivers.

PURPOSE: Complementary and integrative medicine (CIM) services are more prevalent in cancer centers but continue to be underutilized by patients. This study examines perspectives from patients and caregivers about these services being offered at a comprehensive cancer center. METHODS: Patients and caregivers were surveyed about their familiarity, interest, and experience with five CIM therapies: acupuncture, massage, meditation, music therapy, and yoga. Respondents were asked about their interest in and/or paying for these services at baseline, when recommended by their medical team, and when offered in a clinical trial. Respondents were also asked about perceived barriers to accessing these services. Chi-squared tests were performed to explore associations between past experience, interest levels, and willingness to pay. RESULTS: A total of 576 surveys were obtained (464 patients and 112 caregivers). Most respondents identified as White or Caucasian (65.6%), female (57.2%), had been a patient for < 3 years (74.2%), had some college education (73.8%), and made > $40,000 in US dollars as their annual household income (69.1%). Respondents were most familiar with therapeutic massage (34.2%) and least familiar with acupuncture (20.0%). The average interest in these services increased from 53.3% to 64.1% when recommended by a medical professional. Respondents were most willing to pay $1-60 for therapeutic massage (62.3%) and least willing to pay for meditation (43.7%). The main barriers to accessing CIM services were cost (56.0%) and lack of knowledge (52.1%). CONCLUSION: Overall, a significant proportion of patients and caregivers were unfamiliar with these five integrative therapies. Increasing education, decreasing cost, and a recommendation by medical professionals would improve CIM usage.

Association of fatty acid ethyl esters in meconium with behavior during childhood.

OBJECTIVE: To examine associations between amounts of fatty acid ethyl esters (FAEEs) in meconium and behavior in school aged children exposed to alcohol and drugs in utero. METHODS: A secondary analysis of a prospective cohort of cocaine, polydrug exposed children, primarily African-American, low socioeconomic status, recruited at birth into a longitudinal study. FAEEs were quantified with gas chromatography via a flame ionization detector. Meconium was analyzed for FAEEs for 216 newborns of whom 194 were assessed with the Child Behavior Checklist (CBCL) at ages 4, 6, 9, 10, 11, and 12. Generalized estimating equation analyses were used to assess the relationship of quantity of FAEEs to outcomes, controlling for maternal psychological distress. RESULTS: Higher concentrations of FAEEs (ethyl myristate, ethyl palmitate, ethyl oleate, ethyl linoleate, and ethyl linolenate) were associated with caregiver reported aggressive and/or delinquent behavior at ages 10 and 12. After control for caregiver psychological distress, and age, significant (p < 0.05) FAEE by age interactions were found for ethyl myristate for aggression and for ethyl oleate, ethyl linoleate and ethyl linolenate for delinquency. Thus, higher concentrations of FAEE were related to more caregiver reported aggressive and delinquent behaviors of clinical significance at ages 10 and 12. CONCLUSION: Higher concentrations of FAEEs in meconium are potential markers for children at risk for aggressive and delinquent behaviors related to the effects of prenatal alcohol exposure.

Prenatal Substance Exposure and Developmental Trajectories of Internalizing Symptoms: Toddlerhood to Preadolescence.

BACKGROUND: Little is known about how prenatal exposure to substances (alcohol, tobacco, marijuana, and cocaine) may contribute to heterogeneous childhood trajectories of internalizing symptoms (i.e., depression, withdrawal, anxiety). The present study aimed to identify developmental trajectories of internalizing symptoms in children using gender-separate analyses and to examine whether trajectories differ by prenatal substance exposure (PSE) and other environmental and biological correlates. METHODS: Data from two large community-based birth cohorts with PSE were integrated (N = 1,651, 848 boys, 803 girls): the Cleveland cohort and the Maternal Lifestyle Study (MLS). Internalizing symptoms were assessed with the Child Behavior Checklist at ages 2, 4, 6, 9, 10, 11, and 12 in the Cleveland study and at ages 3, 5, 7, 9, 11, and 13 in the MLS. RESULTS: Gender-separate group-based trajectory modeling yielded five distinctive developmental trajectories of internalizing symptoms from ages 2 to 13 in both boys and girls: low-risk group (14.4% girls, 28.8% boys); normative-decreasing group (35.3% girls, 33.1% boys); increasing risk group (14.4% girls, 13.0% boys); early-high group (22.3% girls, 17.9% boys); and chronic group (13.8% girls, 7.2% boys). Prenatal tobacco exposure, maternal psychological distress, and postnatal maternal alcohol use differentiated the longitudinal courses of internalizing symptoms. Boys were more likely to follow the low-risk trajectory, whereas girls were more likely to follow the chronic trajectory. CONCLUSIONS: Prenatal tobacco exposure was associated with suboptimal developmental trajectories of internalizing symptoms in the context of prenatal poly-drug exposure, highlighting a need for continued and increased effort toward prevention of prenatal tobacco use.

Fatty acid ethyl esters in meconium and substance use in adolescence.

Prenatal alcohol exposure (PAE) continues to be a serious public health problem, yet no reliable clinical tools are available for assessing levels of drinking during pregnancy. Fatty acid ethyl esters (FAEEs), the nonoxidative metabolites of ethanol measured in meconium, are potential biomarkers to quantify the level of PAE. The association between the concentrations of FAEEs from meconium and adolescent substance use and related problems was examined in a prospective birth-cohort of adolescents exposed to alcohol and drugs in utero. FAEEs were quantified with gas chromatography via a flame ionization detector. Meconium was analyzed for FAEEs in 216 newborns; 183 of them (81 boys, 102 girls) were assessed at age 15 for alcohol, tobacco, and marijuana use using biologic assays and self-report. Substance use problems were assessed using the Problem Oriented Screening Instrument for Teenagers. Findings from multivariable logistic regression analyses indicated that, after controlling for other prenatal drug exposure and covariates, higher concentrations of FAEEs (ethyl myristate, ethyl palmitate, ethyl oleate, ethyl linoleate, ethyl linolenate, and ethyl arachidonate) were related to a greater likelihood of marijuana use and experiencing substance use problems, but not tobacco or alcohol use, at age 15. Elevated levels of FAEEs in meconium may be promising markers for PAE, identifying newborns at risk for early substance use and developing substance use problems.

Caries disparities among Medicaid-enrolled young children from pediatric primary care settings.

OBJECTIVES: The objectives of this study are to determine the overall and racial differences in the extent of caries experience and to examine the association between child and parent/caregiver characteristics and caries among 3-6-year-old Medicaid-enrolled children. METHODS: This study reports baseline cross-sectional data from a larger pragmatic clinical trial in pediatric primary care practices. Child-level clinical dental exams included decayed and filled teeth (dft) using ICDAS criteria and parent/caregiver questionnaire collected information on socio-demographics, child oral health behaviors, oral health related quality of life (OHQoL), and food environment. RESULTS: A total of 1,024 parent/caregiver-child dyads participated in the study. The overall caries experience (dft) was 49 percent and untreated decay was 42 percent. Children who were Black had 1.3 and 1.2 times significantly higher frequency of untreated primary decay and caries experience compared to non-Black children. An overall logistic regression model predicted that race, increased age, receiving dental care in the past 12 months for a cavity/toothache, and lower caregiver OHQoL was significantly associated with increased odds of the child having caries. Non-Black caregivers with less education, whose child was older, and lower child OHQoL had increased odds of having a child with caries, but these same variables were not predictive for the Black children. CONCLUSIONS: Racial disparities exist with respect to caries experience and untreated decay within a Medicaid-enrolled population of young children attending well-child visits. Pediatric primary care offices are well-positioned to provide dental surveillance and preventive care and could play an important role in decreasing oral health inequities.

Morbidity and Mortality After Burr Hole Craniostomy Versus Craniotomy for Chronic Subdural Hematoma Evacuation: A Single-Center Experience.

BACKGROUND: Chronic subdural hematomas (cSDHs) are common neurosurgical pathological entities and typically occur after trauma in elderly patients. The 2 most commonly used strategies for treatment have included burr hole drainage and craniotomy with decompression. However, the choice of these procedures has remained controversial and has been primarily determined by surgeon preference. We designed a matched-cohort analysis to compare these 2 procedures and identify the risk factors associated with the postoperative outcomes. Thus, we compared the rates of reoperation and mortality for patients who had undergone craniotomy versus burr hole evacuation for cSDH. METHODS: A retrospective review examining the data from 299 consecutive patients with cSHDs from 2002 to 2015 was performed. We compared the following endpoints between the 2 procedures: 30-day mortality, discharge to a skilled nursing facility, and the need for reoperation. We also compared the potential risk factors in the patients with different primary outcomes. RESULTS: Patients undergoing craniotomy had a decreased need for reoperation compared with patients treated with burr hole evacuation (7.5% vs. 15.7%; P = 0.044). Older age was associated with both increased disposition to a nursing facility and increased 30-day mortality in both groups. Increased 30-day mortality was associated with aspirin usage in patients who had undergone craniotomy and with warfarin (Coumadin) in patients who had undergone burr hole evacuation. CONCLUSIONS: Our study identified an increased need for reoperation for patients treated with burr hole evacuation compared with those undergoing craniotomy. Older age and low Glasgow coma scale scores were associated with worse outcomes in both groups. Certain methods of anticoagulation were also associated with worse outcomes, which varied between the 2 groups. We recommend that surgeons individualize the choice of procedure according to the specific patient characteristics with consideration of these findings.

Depressive Symptoms in Older versus Younger People with Epilepsy: Findings from an Integrated Epilepsy Self-Management Clinical Research Dataset.

AIM: There are limited data on psychological outcomes in older people with epilepsy (PWE). This analysis, from a large pooled dataset of clinical studies from the Managing Epilepsy Well (MEW) Network, examined clinical variables including depressive symptom severity, quality of life and epilepsy self-management competency among older (age 55+) vs younger (

Early Therapeutic Mobility and Changes in Scores for Pain and Fatigue.

This report is a secondary analysis of data from a larger study of a nurse-led early therapeutic mobility intervention among patients receiving mechanical ventilation. This analysis evaluated whether intervention frequency or intensity was associated with pain or fatigue. Frequency was defined as once-daily versus twice-daily interventions. Intensity was defined as low (in-bed activities) or moderate (out-of-bed activities). Thirty-nine patients self-reported pain and fatigue immediately before and after the intervention. Neither pain nor fatigue increased significantly (mean increase, <1 [scale of 0-10] for 95% of interventions). Four patients reported decrements in pain; 1 reported a decrease in fatigue. Less than 5% of enrolled patients indicated a score change of +4 to +6 for pain or fatigue, typically with the first intervention that included sitting at the edge of the bed. Future research could examine the distress associated with these symptoms in critically ill adults receiving early therapeutic mobility interventions.

Time to antibody detection and associated factors for presence of anti-drug antibodies in pediatric inflammatory bowel disease patients treated with anti-TNF therapy.

BACKGROUND: Loss of response in pediatric inflammatory bowel disease patients treated with biologic medications can be due to development of anti-drug antibodies. Natural history of anti-drug antibodies development has not been well described in pediatric inflammatory bowel disease. The primary aim of this study was to describe a single-center experience for the temporal onset of anti-drug antibodies detection. METHODS: We performed a retrospective, single-center chart review of pediatric inflammatory bowel disease patients at the Division of Pediatric Gastroenterology, Hepatology, and Nutrition at Rainbow Babies and Children's Hospital from 2010 to 2015. Patients were treated with infliximab or adalimumab and had at least two evaluations for anti-drug antibodies with the homogenous mobility shift assay. Demographics, laboratory and medication data, and clinical disease activity were collected. RESULTS: A total of 75 subjects are included in the analysis. Eighty-one percent of subjects were treated with infliximab. Eleven subjects developed anti-drug antibodies; average time to anti-drug antibodies detection was 13.2 ± 7.3 months. Longer duration of inflammatory bowel disease, L1 location in Crohn's disease, and not having immunomodulatory therapy before biologic was associated with higher risk of antibody detection. Antibody detection occurred more frequently with infliximab vs. adalimumab. Time-to-antibody detection for infliximab and adalimumab was 14.83 and 23.48 months, respectively. CONCLUSION: Chances of anti-drug antibodies detection in the infliximab group were higher than the adalimumab group. Time-to-antibody detection was 8.65 months longer in patients who received adalimumab when compared to infliximab. These results may have implications for long-term therapy and help guide use of concomitant immunomodulators.

Concordance of angiography and cerebral biopsy results for suspected primary central nervous system vasculitis: A multi-center retrospective review.

OBJECTIVE: Primary CNS Vasculitis (PCNSV) is a rare disease that is often challenging to diagnose. Cerebral angiography and biopsy have been utilized in the diagnostic workup for several decades but limited literature reports on the concordance of findings of angiography and biopsy. The primary objective of this work was to examine how cerebral angiography corresponded with biopsy findings in patients with suspected PCNSV. PATIENTS AND METHODS: A total of 128 patients who underwent workup for PCNSV between years 2005-2016 were identified by query of existing neurological surgery and angiography databases at University Hospitals Cleveland Medical Center (UHCMC) and the Cleveland Clinic Foundation (CCF). The primary outcome was to examine the concordance of results between angiography and cerebral biopsy. Secondary outcomes included examining concordance between results of biopsy and other commonly performed tests for diagnosis of PCNSV including Magnetic Resonance Imaging (MRI), cerebrospinal fluid white blood cell count (CSF WBC), Erythrocyte Sedimentation Rate (ESR), C-reactive protein (CRP). RESULTS: 128 patients underwent cerebral biopsy for diagnosis of suspected PCNSV. 93 (73%) of these patients also underwent angiography. Of the 34 patients with positive biopsy findings, only 5 also had positive angiography. Positive angiography was not found to be correlated with positive biopsy in our analysis. The only test that was significantly associated with biopsy proven vasculitis was increased CSF WBC count (P = 0.0114). CONCLUSIONS: PCNSV is a rare disease and often requires multiple tests or procedures to obtain definitive diagnosis. These results suggest that cerebral angiography findings are not associated with biopsy findings and should be used cautiously in the diagnostic work-up of PCNSV.

Subdural Hematoma in Patients with Hematologic Malignancies: An Outcome Analysis and Examination of Risk Factors of Operative and Nonoperative Management.

BACKGROUND: Patients with hematologic disorders who present with subdural hematomas (SDH) present a surgical decision-making challenge. Because of intrinsic coagulopathy, platelet dysfunction, and immunosuppression, surgical intervention poses a unique set of risks. OBJECTIVE: To describe a clinical sample of patients with hematologic disorders and concurrent SDH, to compare baseline and outcome variables, including complication rates and survival, in surgical versus nonsurgical management, and to identify clinical variables that may predict outcomes. METHODS: A 12-year retrospective case-control study was carried out of 50 adult patients with hematologic malignancies and SDH. Patients underwent surgical evacuation for SDH. Controls did not. Outcomes included discharge disposition, Glasgow Outcome Scale score, 30-day mortality, and overall survival. Complications included seizure, reoperation, and readmission. A Fisher exact test or χ2 analysis compared categorical variables; continuous outcomes were compared with a Student t test. A Kaplan-Meier survival analysis was performed and multivariable Cox logistic regression evaluated variables associated with overall mortality. RESULTS: Surgical and nonsurgical groups differed only by Glasgow Coma Scale score, with slightly lower Glasgow Coma Scale scores in the surgical group. Complication rates did not differ; however, the 30-day reoperation rate was 35% for the surgical cohort. Overall, seizure incidence was 18%, readmission was 30%, 30-day mortality was 38%, median survival was 140.5 days, and 75% had a Glasgow Outcome Scale score of 1-3 at censorship. Increased age, low hemoglobin levels, and low platelet levels were associated with increased risk of mortality. CONCLUSIONS: Low platelet and hemoglobin levels are consistent markers of poor prognosis and surgical intervention, either as a proxy of or as a cause for clinical deterioration, is associated with increased mortality risk.

Impact of Dual-Layer Duraplasty During Hemicraniectomy on Morbidity and Operative Metrics of Cranioplasty: A Retrospective Case-Control Study Comparing a Single-Layer with a Dual-Layer Technique.

BACKGROUND: Dural substitutes used during hemicraniectomy provide a barrier and dissection plane during subsequent cranioplasty. A recent review by our group showed that use of dural substitutes in hemicraniectomy is associated with reduction in estimated blood loss (EBL) and operative time (OT). In our experience, the use of a dual-layer technique facilitates a dissection plane with minimal adhesions. We hypothesized that use of this dual-layer technique would show decreased OT and EBL in patients undergoing cranioplasty. METHODS: We conducted a retrospective case-control study comparing use of single-layer versus dual-layer duraplasty on cranioplasty operative outcomes. Data on dual-layer cases were collected from patients who underwent cranioplasty from 2013 to 2017. These data were matched to controls from 2008 to 2012. Patients were identified by query of a neurosurgical database of all procedures performed at our institution. Patients were included if they had complete surgical records for cranioplasty. Cases and controls were compared with a Student t test, χ2 test, or Fisher exact test. RESULTS: A total of 78 controls and 45 cases met inclusion criteria. All baseline characteristics between cohorts were similar except for surgical indication. Mean OT (102.97 minutes vs. 102.18 minutes) and mean EBL were not significantly different (204.66 mL vs. 190 mL) between cohorts. CONCLUSIONS: In this study, we did not detect any significant difference between EBL and OT with use of single-layer versus dual-layer duraplasty. Mean EBL was slightly higher in the controls compared with cases but this difference was not statistically or clinically significant. This concept would benefit from a prospective randomized study.

Enhancing Multi-Center Patient Cohort Studies in the Managing Epilepsy Well (MEW) Network: Integrated Data Integration and Statistical Analysis.

Self-management techniques that assist patients with chronic conditions, such as epilepsy, diabetes, and arthritis, play an important role in managing and caring for their conditions. The US Center for Disease Control and Prevention (CDC)-funded Managing Epilepsy Well (MEW) Network consists of 11 study sites across the US that aims to develop and disseminate self-management techniques for epilepsy patients. Epilepsy affects more than 65 million patients worldwide with serious negative impact on their own as well as their family member's quality of life. Taking advantage of advances in biomedical informatics, the MEW Network has created an integrated database (MEW DB) using a common data model and two tiers of study variables. The MEW DB consists of 1680 patient data records covering a wide range of patient population nationwide. Therefore, there is growing interest in the use of the MEW DB for different cohort query analysis. To address the challenges in: (1) selecting appropriate MEW research studies based on inclusion/exclusion criteria; (2) creating a patient cohort for given research hypothesis; and (3) performing appropriate statistical tests; we have developed an integrated data query and statistical analysis informatics tool called Insight. The Insight platform features an intuitive user interface to support the three phases of study selection, patient cohort creation, and statistical testing with the use of an epilepsy domain ontology to support ontology-driven query expansion. We evaluate the Insight platform using two user evaluation methods of "first click testing" and "user satisfaction survey". In addition, we performed a time performance test of the Insight platform using four patient datasets and three statistical test. The results of the user evaluation show that Insight platform is strongly approved by the users and the results of the time performance show that there is marginal difference in performance as the volume of patient data increases in the MEW DB.

Dose of Early Therapeutic Mobility: Does Frequency or Intensity Matter?

OBJECTIVE: Investigate the feasibility of a nurse-led mobility protocol and compare the effects of once- versus twice-daily episodes of early therapeutic mobility (ETM) and low- versus moderate-intensity ETM on serum biomarkers of inflammation and selected outcomes in critically ill adults. DESIGN: Randomized interventional study with repeated measures and blinded assessment of outcomes. SETTING: Four adult intensive care units (ICUs) in two academic medical centers. SUBJECTS: Fifty-four patients with > 48 hr of mechanical ventilation (MV). INTERVENTION: Patients were assigned to once- or twice-daily ETM via sealed envelope randomization at enrollment. Intensity of (in-bed vs. out-of-bed) ETM was administered according to protocolized patient assessment. MEASUREMENTS: Interleukins 6, 10, 8, 15, and tumor necrosis factor-α were collected from serum before and after ETM; change scores were used in the analyses. Manual muscle and handgrip strength, delirium onset, duration of MV, and ICU length of stay (LOS) were evaluated as patient outcomes. MAIN RESULTS: Hypotheses regarding the inflammatory biomarkers were not supported based on confidence intervals. Twice-daily intervention was associated with reduced ICU LOS. Moderate-intensity (out-of-bed) ETM was associated with greater manual muscle test scores and handgrip strength and reduced occurrence of delirium. CONCLUSION: Findings from this study suggest that nurses can provide twice-daily mobility interventions that include sitting on the edge of the bed once patients have a stable status without altering a pro-inflammatory serum biomarker profile.
