Scoping Review of Racial, Ethnic, and Sex Disparities in the Diagnosis and Management of Hemorrhagic Stroke. Neurology 2023:WNL.0000000000207406. [PMID: 37202159 PMCID: PMC10382273 DOI: 10.1212/wnl.0000000000207406] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/13/2022] [Accepted: 03/28/2023] [Indexed: 05/20/2023] Open
Abstract
BACKGROUND AND OBJECTIVES In the United States, Black, Hispanic, and Asian Americans suffer from excessively high incidence rates of hemorrhagic stroke compared to White Americans. Women suffer from higher rates of subarachnoid hemorrhage than men. Previous reviews detailing racial, ethnic, and sex disparities in stroke have focused on ischemic stroke. We performed a scoping review of disparities in the diagnosis and management of hemorrhagic stroke in the United States to identify areas of disparities, research gaps, and evidence to inform efforts aimed at health equity. METHODS We included studies published after 2010 that assessed racial and ethnic or sex disparities in the diagnosis or management of patients 18 years or older in the United States with a primary diagnosis of spontaneous intracerebral hemorrhage or aneurysmal subarachnoid hemorrhage. We did not include studies assessing disparities in incidence, risks, or mortality and functional outcomes of hemorrhagic stroke. RESULTS After reviewing 6161 abstracts and 441 full texts, 59 studies met our inclusion criteria. Four themes emerged. First, few data address disparities in acute hemorrhagic stroke. Second, racial and ethnic disparities in blood pressure control following intracerebral hemorrhage exist and likely contribute to disparities in recurrence rates. Third, racial and ethnic differences in end-of-life-care exist, but further work is required to understand whether these differences represent true disparities in care. Fourth, very few studies specifically address sex disparities in hemorrhagic stroke care. DISCUSSION Further efforts are necessary to delineate and correct racial, ethnic, and sex disparities in the diagnosis and management of hemorrhagic stroke.

The Impact of Population Ageing on Rural Aged Care Needs in Australia: Identifying Projected Gaps in Service Provision by 2032. Geriatrics (Basel) 2023; 8:geriatrics8030047. [PMID: 37218827 DOI: 10.3390/geriatrics8030047] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/17/2023] [Revised: 04/25/2023] [Accepted: 04/25/2023] [Indexed: 05/24/2023] Open
Abstract
This observational study examines and estimates the trends and impact of population ageing on rural aged care needs in Australia. With its universal health system and subsidised aged care system, Australia is among those countries with a long life expectancy. Being a geographically large country with a relatively small and dispersed population presents challenges for equitable access to aged care service provision. While this is widely acknowledged, there is little empirical evidence to demonstrate the magnitude and location of the aged care service provision gaps in the next decade. We performed time series analyses on administrative data from the Australian Bureau of Statistics and the Australian Institute of Health and Welfare GEN databases. The Aged Care Planning Regions (ACPR) were classified according to geographical remoteness using the Modified Monash Model scale. There is currently a shortfall of 2000+ places in residential aged care in rural and remote areas of Australia based on 2021 data. By 2032, population ageing will mean that an additional 3390 residential care places and around 3000 home care packages will be required in rural and remote communities alone. Geographical disparities in aged care exist in Australia and continue to worsen, requiring immediate action.

Abstract
Background Mirikizumab (miri) improved symptom control in a Phase 3, multicenter, randomized, double-blind, parallel, placebo-controlled induction study at Week (W)12, in patients (pts) with moderately-to-severely active ulcerative colitis (UC; LUCENT-1). Purpose This analysis assessed sustained symptom control during the maintenance phase through W40 (W52 of continuous therapy), among pts who were induced into clinical response with miri. Method During the 40W maintenance study (LUCENT-2), pts (N=544) who achieved clinical response to miri 300mg Q4W by W12 of induction, were re-randomized 2:1 to subcutaneous (SC) miri 200mg (n=365) or PBO Q4W (n=179). We evaluated sustained control of stool frequency (SF), rectal bleeding (RB), bowel movement urgency (BU) and abdominal pain (AP). The proportion of pts achieving SF Remission (defined as SF=0, or SF=1 with a ≥1-point decrease from induction baseline [BL]), RB Remission (RB=0), Symptomatic Remission (both SF and RB Remission), Stable Maintenance of Symptomatic Remission (defined as pts in Symptomatic Remission for at least 7 out of 9 visits from W4 to W36 and also at Week 40 among pts in Symptomatic Remission and Clinical Response at the end of LUCENT-1), and AP Improvement (Numeric Rating Scale [NRS] pain score ≥30% improvement from BL in pts with baseline AP NRS ≥3) were assessed. BU NRS change from baseline, and the proportion of pts achieving BU Remission (NRS 0 or 1 in pts with BU NRS ≥3 at baseline) were evaluated. Result(s) A greater proportion of miri-treated pts achieved SF Remission, RB Remission and Symptomatic Remission compared to PBO at W40 (Table), with significant differences observed from W8 of LUCENT-2 (p=0.042; p=0.004; p=0.036, respectively) and maintained through W40. Miri-treated pts had a significantly higher percentage of Stable Maintenance of Symptomatic Remission (p<0.001). Pts in the miri-treatment group had a significantly greater mean reduction in BU NRS change from induction BL starting at W12 (p=0.034) onwards compared to PBO (Table). Pts assigned to miri accrued an additional 13.6 percentage-point benefit in BU Remission during the first 8W of maintenance therapy and achieved a significant greater improvement at W40 compared to PBO (p<0.001, Table). Similarly, AP was significantly improved for the miri-treated group starting at W16 (p=0.034) onwards compared to PBO. Image ![]()
Conclusion(s) Miri provides sustained control of UC symptoms including BU, RB, and SF compared to PBO in pts with moderately to severely active UC.

A31 MIRIKIZUMAB IMPROVES QUALITY OF LIFE IN MODERATELY-TO-SEVERELY ACTIVE UC: IMPROVEMENT IN IBDQ SCORES IN PARTICIPANTS OF LUCENT-1 AND LUCENT-2 RANDOMIZED, DOUBLE-BLIND, PLACEBO-CONTROLLED PHASE 3 TRIALS. J Can Assoc Gastroenterol 2023.

Abstract
Background The inflammatory bowel disease questionnaire (IBDQ) is a measure of health-related quality of life (QoL), with higher scores indicating greater QoL. In a prior phase 2 study (NCT02589665), mirikizumab, an anti-IL23p19 antibody, demonstrated efficacy and improvement in IBDQ scores in participants with moderately to severely active ulcerative colitis (UC). Purpose This analysis evaluated effect of mirikizumab (miri) vs placebo (PBO) on IBDQ scores in patients (pts) with moderately to severely active ulcerative colitis (UC) who had failed prior conventional or biologic therapy in a Phase 3, double-blind, 12-week (W) induction study (LUCENT-1) followed by a 40W maintenance study (LUCENT-2) for a total of 52W continuous therapy. Method Pts (N=1162) in LUCENT-1 were randomized 3:1 to receive 300mg miri or PBO intravenously once every four weeks (Q4W). 544 pts who achieved Modified Mayo Score Clinical Response to miri by W12 of induction were rerandomized 2:1 in LUCENT-2 to subcutaneous miri 200mg or PBO Q4W in maintenance period. Randomization was stratified by previous biologic therapy failure, baseline corticosteroid use, and region. LUCENT-1 stratification included baseline (BL) disease activity, and LUCENT-2 included LUCENT-1 clinical remission status. The least squares mean change from BL in IBDQ scores at W12 of induction and W40 of maintenance was determined using analysis of covariance models. BL was W0 of therapy and stratification factors and BL scores were used as covariates. The Minimal Clinically Important Difference (MCID) was defined as an improvement of ≥16 points in total IBDQ score (IBDQ response) and IBDQ remission as a total score ≥170 points. IBDQ response and remission were calculated using non-responder imputations. Treatments were compared using the common risk difference (risk diff). Result(s) Miri treatment resulted in significantly greater improvement from BL in IBDQ total and domain scores vs PBO at both W12 of induction and W40 of maintenance (52W treatment) (Table). The proportions of pts who achieved an IBDQ response was significantly greater for miri treated pts vs PBO at W12 (risk diff =17.1[95%CI:10.7, 23.5]) and W40 (29.5 [21.0, 37.9]). Significantly greater proportions of pts receiving miri achieved IBDQ remission at W12 (18.1 [11.8, 24.4]) and W40 (28.5 [20.1, 37.0]) vs PBO (all evaluations and timepoints: p<0.001). Image ![]()
Conclusion(s) Pts reported significantly greater improvements in IBDQ scores at induction and maintenance with miri compared to PBO. Over 75% of pts achieved a clinically meaningful improvement in QoL, as measured by IBDQ response, at the end of the 52 weeks of miri treatment.

Abstract
Background Mirikizumab (miri), an anti-IL23/p19 monoclonal antibody, demonstrated efficacy compared with placebo (PBO) in the Phase 3, multicentre, randomized, double-blind LUCENT-1 induction study in patients with moderately to severely active ulcerative colitis (UC, NCT03518086). Purpose This analysis assessed early onset of symptomatic improvement and symptomatic control during induction. Method During the 12-week (W) induction study, 1162 adult patients (pts) with inadequate response, loss of response, or were intolerant to conventional therapy or biologic or tofacitinib therapy for UC, received miri IV Q4W (N=868) or PBO (N=294). We evaluated improvement for symptoms of stool frequency (SF), rectal bleeding (RB) and bowel movement urgency (BU), abdominal pain and fatigue. BU Numeric Rating Scale (NRS) change from baseline (BL), BU Clinical Meaningful Improvement (CMI), BU Remission, Fatigue NRS change from BL, Abdominal Pain Improvement, as well as SF Remission, RB Remission, Symptomatic Response and Symptomatic Remission were assessed. Result(s) As early as W2, miri-treated pts achieved a significantly greater reduction in RB subscores (p=0.001) and in SF subscores (p=0.035). From W2 and W4, a significantly greater percentage achieved SF Remission and RB Remission, respectively compared to PBO. A significantly greater percentage of miri-treated pts achieved Symptomatic Response compared to PBO from W2 (p=0.003) and of Symptomatic Remission compared with PBO from W4 (p<0.001). Miri-treated pts showed a significantly greater mean reduction in BU NRS scores as early as W2 compared to PBO (p=0.004). From W4, a significantly greater percentage of miri-treated pts achieved BU CMI versus PBO (p=0.044). From W7 onwards, a significantly greater percentage achieved BU Remission (p=0.002). The pts showed a significantly greater mean reduction in Fatigue NRS scores from W2 compared to PBO (p=0.014). As early as W4, a significant reduction of at least 30% in Abdominal Pain NRS score from BL was observed in the miri-treated pts compared with PBO (p=0.007). At W12, a significantly greater proportion of miri-treated pts achieved Symptomatic Response, Symptomatic Remission, RB Remission, SF Remission, BU change from BL, BU CMI and Remission, as well as Fatigue and Abdominal Pain Improvement, compared to PBO (Table).

Abstract WMP66: Early Rising Pain Scores Predict Cerebral Vasospasm After Aneurysmal Subarachnoid Hemorrhage. Stroke 2023.

Abstract
Introduction:
Persistent pain following subarachnoid hemorrhage (SAH) is common and follows distinct trajectories. Cerebral vasospasm (CV) and delayed cerebral ischemia are late complications of SAH and may represent modifiable causes of secondary brain injury. Headache and CV share common risk factors including age, blood burden and cigarette smoking, however the relationship between pain and CV is unknown. We hypothesize that patients with increasing pain will be at increased risk for developing CV.
Methods:
We conducted a retrospective review of patients with non-traumatic SAH at two large academic medical centers from 2015-2022. Pain scores were recorded for 14 days. We excluded patients with onset of CV before post-bleed day (PBD) 4. We employed group-based trajectory modeling to identify distinct trajectories of 24 q2h pain scores during PBDs 2 and 3. Pain scores prior to PBD 2 were omitted due to the large amount of missing data. The incidence of CV was compared between trajectory groups using chi-squared analysis.
Results:
We identified 442 patients (median [IQR] age 56 [47-64] years, 294 (66%) women, 33 (7.4%) peri-mesencephalic, 330 (75%) Hunt-Hess 1-3, 393 (88%) modified Fisher 3-4) for analysis. We considered 3 through 8-group models and compared model fit by comparing AIC, BIC, and visual inspection of trajectories between models. Ultimately, a 4-group model fit the data best with four distinct trajectories of pain: persistently low (41% of patients), persistently high (24%), falling (18%) and rising (16%). Baseline clinical variables were comparable between trajectory groups. The median [IQR] day of CV onset was PBD 7 [5-10]. Patients with rising pain had significantly higher rates of vasospasm than those with persistently high or falling pain (54% vs 34% and 36%, respectively, Chi2 P = 0.02). Results were similar in a sensitivity analysis limited to patients with verbally reported pain scores.
Conclusion:
Distinct pain trajectories exist in the early hospital course following SAH. Our multicenter, retrospective cohort found that an initial rising pain trajectory is associated with development of CV. Future studies should validate this finding in separate cohorts and explore the pathophysiological mechanisms of this association.

Abstract
BACKGROUND AND OBJECTIVE To test the hypothesis that age-specific, sex-specific, and race-specific and ethnicity-specific incidence of nontraumatic subarachnoid hemorrhage (SAH) increased in the United States over the last decade. METHODS In this retrospective cohort study, validated International Classification of Diseases codes were used to identify all new cases of SAH (n = 39,475) in the State Inpatients Databases of New York and Florida (2007-2017). SAH counts were combined with Census data to calculate incidence. Joinpoint regression was used to compute the annual percentage change (APC) in incidence and to compare trends over time between demographic subgroups. RESULTS Across the study period, the average annual age-standardized/sex-standardized incidence of SAH in cases per 100,000 population was 11.4, but incidence was significantly higher in women (13.1) compared with that in men (9.6), p < 0.001. Incidence also increased with age in both sexes (men aged 20-44 years: 3.6; men aged 65 years or older: 22.0). Age-standardized and sex-standardized incidence was greater in Black patients (15.4) compared with that in non-Hispanic White (NHW) patients (9.9) and other races and ethnicities, p < 0.001. On joinpoint regression, incidence increased over time (APC 0.7%, p < 0.001), but most of this increase occurred in men aged 45-64 years (APC 1.1%, p = 0.006), men aged 65 years or older (APC 2.3%, p < 0.001), and women aged 65 years or older (APC 0.7%, p = 0.009). Incidence in women aged 20-44 years declined (APC -0.7%, p = 0.017), while those in other age/sex groups remained unchanged over time. Incidence increased in Black patients (APC 1.8%, p = 0.014), whereas that in Asian, Hispanic, and NHW patients did not change significantly over time. DISCUSSION Nontraumatic SAH incidence in the United States increased over the last decade predominantly in middle-aged men and elderly men and women. Incidence is disproportionately higher and increasing in Black patients, whereas that in other races and ethnicities did not change significantly over time.

[PMID: 34331206 PMCID: PMC9847350 DOI: 10.1007/s12028-021-01303-3] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/07/2021] [Accepted: 06/14/2021] [Indexed: 01/21/2023]
Abstract
BACKGROUND Intracranial pressure waveform morphology reflects compliance, which can be decreased by ventriculitis. We investigated whether morphologic analysis of intracranial pressure dynamics predicts the onset of ventriculitis. METHODS Ventriculitis was defined as culture or Gram stain positive cerebrospinal fluid, warranting treatment. We developed a pipeline to automatically isolate segments of intracranial pressure waveforms from extraventricular catheters, extract dominant pulses, and obtain morphologically similar groupings. We used a previously validated clinician-supervised active learning paradigm to identify metaclusters of triphasic, single-peak, or artifactual peaks. Metacluster distributions were concatenated with temperature and routine blood laboratory values to create feature vectors. A L2-regularized logistic regression classifier was trained to distinguish patients with ventriculitis from matched controls, and the discriminative performance using area under receiver operating characteristic curve with bootstrapping cross-validation was reported. RESULTS Fifty-eight patients were included for analysis. Twenty-seven patients with ventriculitis from two centers were identified. Thirty-one patients with catheters but without ventriculitis were selected as matched controls based on age, sex, and primary diagnosis. There were 1590 h of segmented data, including 396,130 dominant pulses in patients with ventriculitis and 557,435 pulses in patients without ventriculitis. There were significant differences in metacluster distribution comparing before culture-positivity versus during culture-positivity (p < 0.001) and after culture-positivity (p < 0.001). The classifier demonstrated good discrimination with median area under receiver operating characteristic 0.70 (interquartile range 0.55-0.80). There were 1.5 true alerts (ventriculitis detected) for every false alert. CONCLUSIONS Intracranial pressure waveform morphology analysis can classify ventriculitis without cerebrospinal fluid sampling.

Initial Stress Hyperglycemia Is Associated With Malignant Cerebral Edema, Hemorrhage, and Poor Functional Outcome After Mechanical Thrombectomy. Neurosurgery 2022; 90:66-71. [PMID: 34982872 DOI: 10.1227/neu.0000000000001735] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/02/2021] [Accepted: 08/10/2021] [Indexed: 01/04/2023] Open
Abstract
BACKGROUND Malignant cerebral edema (MCE) and intracranial hemorrhage (ICH) are associated with poor neurological outcomes despite revascularization after mechanical thrombectomy (MT). The factors associated with the development of MCE and ICH after MT are not well understood. OBJECTIVE To determine periprocedural factors associated with MCE, ICH, and poor functional outcome. METHODS We retrospectively analyzed anterior cerebral circulation large vessel occlusion cases that underwent MT from 2012 to 2019 at a single Comprehensive Stroke Center. Multivariate logistic regression analyses were performed to determine significant predictors of MCE, ICH, and poor functional outcome (modified Rankin Scale, 3-6) at 90 d. RESULTS Four hundred patients were included. Significant independent predictors of MCE after MT included initial stress glucose ratio (iSGR) (odds ratio [OR], 14.26; 95% CI, 3.82-53.26; P < .001), National Institutes of Health Stroke Scale (NIHSS) (OR, 1.10; 95% CI, 1.03-1.18; P = .008), internal carotid artery compared with M1 or M2 occlusion, and absence of successful revascularization (OR, 0.16; 95% CI, 0.06-0.44; P < .001). Significant independent predictors of poor functional outcome included MCE (OR, 7.47; 95% CI, 2.20-25.37; P = .001), iSGR (OR, 5.15; 95% CI, 1.82-14.53; P = .002), ICH (OR, 4.77; 95% CI, 1.20-18.69; P = .024), NIHSS (OR, 1.10; 95% CI, 1.05-1.16; P < .001), age (OR, 1.04; 95% CI, 1.03-1.07; P < .001), and thrombolysis in cerebral infarction 2C/3 recanalization (OR, 0.12; 95% CI, 0.05-0.29; P < .001). CONCLUSION Elevated iSGR significantly increases the risk of MCE and ICH and is an independent predictor of poor functional outcome. Thrombolysis in cerebral infarction 2C/3 revascularization is associated with reduced risk of MCE, ICH, and poor functional outcome. Whether stress hyperglycemia represents a modifiable risk factor is uncertain, and further investigation is warranted.

Abstract
INTRODUCTION Aneurysmal subarachnoid hemorrhage (SAH) survivors live with long-term residual physical and cognitive disability. We studied whether neuromuscular electrical stimulation (NMES) and high-protein supplementation (HPRO) in the first 2 weeks after SAH could preserve neuromotor and cognitive function as compared to standard of care (SOC) for nutrition and mobilization. METHODS SAH subjects with a Hunt Hess (HH) grade > 1,modified Fisher score > 1 and BMI < 40 kg/m2 were randomly assigned to SOC or NMES + HPRO. NMES was delivered to bilateral quadricep muscles daily during two 30-min sessions along with HPRO (goal:1.8 g/kg/day) between post-bleed day (PBD) 0 and 14. Primary endpoint was atrophy in the quadricep muscle as measured by the percentage difference in the cross-sectional area from baseline to PBD14 on CT scan. All subjects underwent serial assessments of physical (short performance physical battery, SPPB) cognitive (Montreal Cognitive Assessment Scale, MoCA) and global functional recovery (modified Rankin Scale, mRS) at PBD 14, 42, and 90. RESULTS Twenty-five patients (SOC = 13, NMES + HPRO = 12) enrolled between December 2017 and January 2019 with no between-group differences in baseline characteristics (58 years old, 68% women, 50% HH > 3). Median duration of interventions was 12 days (range 9-14) with completion of 98% of NMES sessions and 83% of goal HPRO, and no reported serious adverse events. There was no difference in caloric intake between groups, but HPRO + NMES group received more protein (1.5 ± 0.5 g/kg/d v 0.9 ± 0.4 g/kg/d, P < 0.01). Muscle atrophy was less in NMES + HPRO than the SOC group (6.5 ± 4.1% vs 12.5 ± 6.4%, P 0.01). Higher atrophy was correlated with lower daily protein intake (ρ = - 0.45, P = 0.03) and lower nitrogen balance (ρ = 0.47, P = 0.02); and worse 3 month SPPB (ρ = - 0.31, P = 0.1) and mRS (ρ = 0.4, P = 0.04). NMES + HPRO patients had a better median [25%,75] SPPB (12[10, 12] v. 9 [4, 12], P = 0.01) and mRS (1[0,2] v.2[1, 3], P = 0.04) than SOC at PBD 90. CONCLUSIONS NMES + HPRO appears to be feasible and safe acutely after SAH and may reduce acute quadriceps muscle wasting with a lasting benefit on recovery after SAH.

Abstract
<sec> <title>BACKGROUND</title> In KwaZulu-Natal, South Africa, the incidence of extensively drug-resistant tuberculosis (XDR-TB) is driven by the transmission of resistant strains. As data suggest that cases may be spatially clustered, we sought to identify 'hotspots' and describe these communities. </sec> <sec> <title>METHODS</title> We enrolled XDR-TB patients diagnosed from 2011 to 2014 in eThekwini. Global positioning system (GPS) coordinates for participant homes were collected and hotspots were identified based on population-adjusted XDR-TB incidence. The sociodemographic features of hotspots were characterised using census data. For a subset of participants, we mapped non-home XDR-TB congregate locations and compared these with results including only homes. </sec> <sec> <title>RESULTS</title> Among 132 participants, 75 (57%) were female and 87 (66%) lived in urban or suburban locations. Fifteen of 197 census tracts were identified as XDR-TB hotspots with ≥95% confidence. Four spatial mapping methods identified one large hotspot in northeastern eThekwini. Hotspot communities had higher proportions of low educational attainment (12% vs. 9%) and unemployment (29.3% vs. 20.4%), and lower proportion of homes with flush toilets (36.4% vs. 68.9%). The case density shifted towards downtown Durban when congregate locations (e.g., workplaces) for 43 (33%) participants were mapped. </sec> <sec> <title>CONCLUSIONS</title> In eThekwini, XDR-TB case homes were clustered into hotspots with more poverty indicators than non-hotspots. Prevention efforts targeting hotspot communities and congregate settings may be effective in reducing community transmission. </sec>.

Abstract
Background: Early nutritional support of preterm infants is important because it influences long-term health and development. Body composition has an influence on cardiovascular disease, metabolic syndrome, and neurocognitive outcome in the long term. Objective: To assess body composition in preterm infants <32 weeks of gestation at term-equivalent age and to analyze the influence of an optimized nutritional approach. Methods: This is a prespecified secondary outcome analysis of a prospective observational study comparing the body composition in regard to gestational age. The preterm infants were classified according to gestational age as extremely preterm infants (<28 weeks gestation at birth) and very preterm infants (≥28 weeks gestation at birth) and according to weight percentile as appropriate for gestational age and small for gestational age. Body composition was determined by air displacement plethysmography using the PEA POD. The preterm infants obtained nutrition according to the ESPGHAN 2010 Guidelines. Results: Seventy-four preterm infants were analyzed. The mean (SD) gestational age was 28.7 (2.4) weeks, and birth weight was 1,162 (372) g. Fat mass percentage was significantly higher in extremely preterm infants in comparison to very preterm infants [17.0, 95% confidence interval (CI) 15.9-18.1 vs. 15.5, 95% CI 14.7-16.2]. There was no significant difference of fat mass percentage according to weight percentiles. Conclusions: Extremely preterm infants had a significantly higher fat mass percentage compared to very preterm infants at term-equivalent age. There was no significant difference of fat mass percentage according to weight percentiles.

Abstract
PURPOSE OF REVIEW The goal of this review is to highlight the influence of therapeutic maneuvers on neuro-prognostication measures administered to comatose survivors of cardiac arrest. We focus on the effect of sedation regimens in the setting of targeted temperature management (TTM), one of the principle interventions known to improve neurological recovery after cardiac arrest. Further, we discuss the critical need for novel markers, as well as refinement of existing markers, among patients receiving extracorporeal membrane oxygenation (ECMO) in the setting of failed conventional resuscitation, known as extracorporeal cardiopulmonary resuscitation (ECPR). RECENT FINDINGS Automated pupillometry may have some advantage over standard pupillary examination for prognostication following TTM, sedation, or the use of ECMO after cardiac arrest. New serum biomarkers such as Neurofilament light chain have shown good predictive abilities and need further validation in these populations. There is a high-level uncertainty in brain death declaration protocols particularly related to apnea testing and appropriate ancillary tests in patients receiving ECMO. Both sedation and TTM alone and in combination have been shown to affect prognostic markers to varying degrees. The optimal approach to analog-sedation is unknown, and requires further study. Moreover, validation of known prognostic markers, as well as brain death declaration processes in patients receiving ECMO is warranted. Data on the effects of TTM, sedation, and ECMO on biomarkers (e.g., neuron-specific enolase) and electrophysiology measures (e.g., somatosensory-evoked potentials) is sparse. The best approach may be one customized to the individual patient, a precision-medicine approach.

Abstract
BACKGROUND Preterm birth is a medical emergency and it is becoming evident that adequate nutrition starting in the first hours of life is of major importance for short and even more so for long-term health outcomes of the premature newborn. The aim was to analyze postnatal nutrient supply and growth patterns of preterm infants in response to a standardized feeding protocol during stay at neonatal intensive care unit (NICU). METHODS A prospective cohort study was conducted at NICU, Children Hospital Graz. Infants were divided in two groups:<28 weeks (Extremely preterm infants, EPI); ≥28 weeks (very preterm infants, VPI). RESULTS EPI compared to VPI stayed longer on parenteral nutrition and needed more time to reach full enteral nutrition, required more days on ventilation and had a higher corrected age at discharge. Moreover, fortification of enteral feeds was initiated later in EPI group (p < 0.001). As a consequence, cumulative supply of protein, fat and energy was significantly lower in EPI. However, both groups exceeded the European Society of Gastroenterology, Hepatology and Nutrition (ESPGHAN) recommended glucose intake in week 5. At discharge, we found significant differences in all growth parameters (weight Z scores: EPI = - 1.19 vs VPI = - 0.71, length Z scores: EPI = - 1.62 vs VPI = - 0.84; HC Z scores: EPI = - 1.19 vs VPI = - 0.46). CONCLUSIONS Provision of aggressive parenteral nutrition during first 3 weeks of life and earlier fortification should be ensured. The use of mother milk fortifier resulted in glucose intake above the ESPGHAN recommendations in later weeks - this needs to be evaluated in future studies.

Abstract
The lubricant-surface system is complex in nature and can significantly affect the frictional performance of high-performance transmission systems. The complexity stems from the coupled mechanical and chemical phenomena that occur at the interfacial tooth conjunctions. A combined analytical and precision experimental approach is presented to analyse the salient parameters of the lubricant-surface system. A multiscale procedure comprising topographical measurement, pin-on-disc tribometry, atomic force microscopy in lateral force mode, X-ray photo-electron spectroscopy and continuum contact mechanics analysis under mixed non-Newtonian thermo-elastohydrodynamics is used to describe the formation of a tribo-film, as well as wear and frictional characteristics of the lubricant-surface system. The contribution of chemisorbed and physisorbed bonded tribo-film on the boundary coefficient of friction is ascertained at different physical scales. Therefore, the paper presents a novel multiscale analysis, promoting improved understanding of the complex interactions between mechanisms of friction, wear and surface chemistry.

Abstract
Introduction:
We sought to determine the medical specialty and training of U.S. physicians who perform mechanical thrombectomy for stroke.
Methods:
We analyzed claims between 2009-2015 from a 5% nationally representative sample of Medicare beneficiaries ≥65 years of age. Validated
ICD-9-CM
diagnosis codes were used to identify hospitalizations for acute ischemic stroke. Mechanical thrombectomy was defined as a physician claim with
CPT
code 37184 and an accompanying diagnosis of cerebrovascular disease. Medical specialty was identified using the claim’s Medicare provider specialty code. We reviewed public online profiles to ascertain providers’ residency and fellowship training. Statistical analysis involved chi-square tests and kappa statistics.
Results:
During 77,774 stroke hospitalizations, we identified 555 thrombectomies, of which 341 (61.4%; 95% CI, 57.2-65.5%) were performed by radiologists, 110 (19.8%; 95% CI, 16.6-23.4%) by neurologists, 91 (16.4%; 95% CI, 13.4-19.7%) by neurosurgeons, and 13 (2.3%; 95% CI, 1.3-4.0%) by others such as cardiologists and vascular surgeons. Of the 555 procedures, 367 (66.1%; 95% CI, 62.0-70.1%) were performed by a physician who had completed a dedicated neurointerventional fellowship. There was excellent agreement (91.4%; kappa, 0.86) between Medicare specialty designations and the online profiles of the 350 physicians who performed these 555 procedures. The rate of mechanical thrombectomy rose from 0.62% (95% CI, 0.56-0.68%) before publication of the MR CLEAN trial to 1.45% (95% CI, 1.21-1.72%) after, but there was no significant change after its publication in the distribution of providers’ specialties or the proportion of procedures performed by those with neurointerventional fellowship training (Figure).
Conclusions:
Most mechanical thrombectomies for stroke in the U.S. are performed by radiologists, neurologists, and neurosurgeons with dedicated neurointerventional fellowship training.

Abstract
We deal with the following question: Can the consumption of contaminated bush meat, the funeral practices and the environmental contamination explain the recurrence and persistence of Ebola virus disease outbreaks in Africa? We develop an SIR-type model which, incorporates both the direct and indirect transmissions in such a manner that there is a provision of Ebola viruses. We prove that the full model has one (endemic) equilibrium which is locally asymptotically stable whereas, it is globally asymptotically stable in the absence of the Ebola virus shedding in the environment. For the sub-model without the provision of Ebola viruses, the disease dies out or stabilizes globally at an endemic equilibrium. At the endemic level, the number of infectious is larger for the full model than for the sub-model without provision of Ebola viruses. We design a nonstandard finite difference scheme, which preserves the dynamics of the model. Numerical simulations are provided.

Abstract
The unique challenges presented by metabolomics have driven the development of new mass spectrometry (MS)-based techniques for small molecule analysis. We have previously demonstrated silicon nanopost arrays (NAPA) to be an effective substrate for laser desorption ionization (LDI) of small molecules for MS. However, the utility of NAPA-LDI-MS for a wide range of metabolite classes has not been investigated. Here we apply NAPA-LDI-MS to the large-scale acquisition of high-resolution mass spectra and tandem mass spectra from a collection of metabolite standards covering a range of compound classes including amino acids, nucleotides, carbohydrates, xenobiotics, lipids, and other classes. In untargeted analysis of metabolite standard mixtures, detection was achieved for 374 compounds and useful MS/MS spectra were obtained for 287 compounds, without individual optimization of ionization or fragmentation conditions. Metabolite detection was evaluated in the context of 31 metabolic pathways, and NAPA-LDI-MS was found to provide detection for 63% of investigated pathway metabolites. Individual, targeted analysis of the 20 common amino acids provided detection of 100% of the investigated compounds, demonstrating that improved coverage is possible through optimization and targeting of individual analytes or analyte classes. In direct analysis of aqueous and organic extracts from human serum samples, spectral features were assigned to a total of 108 small metabolites and lipids. Glucose and amino acids were quantitated within their physiological concentration ranges. The broad coverage demonstrated by this large-scale screening experiment opens the door for use of NAPA-LDI-MS in numerous metabolite analysis applications.

Abstract
INTRODUCTION Intra-aortic counterpulsation balloon pumps (IABPs) have been widely used to augment hemodynamics in critically ill patients with cardiogenic shock and have recently been proposed as a management strategy for subarachnoid hemorrhage (SAH) patients with neurogenic stress cardiomyopathy (NSC). Prior case series have described the use of IABP as a means to manage cardiogenic shock in this patient population; however, we sought to describe our experience with IABP as a means to wean vasopressor requirement while augmenting hemodynamics and maintaining pressures at goal. METHODS Five patients were identified from a single center, prospective, observational cohort study that received an IABP for the management of ischemia related to cerebral vasospasm in the setting of NSC. We evaluated all cases for efficacy of IABP in reducing vasopressor requirement, and complications. RESULTS Vasopressor requirements were reduced by a mean of 50% (range 25-65%) following IABPs placement within 24-48 h. There were no significant complications from IABPs. Out of the five patients, the outcome in three cases was favorable (mRS≤1). Two patients suffered delayed cerebral ischemia (DCI), one patient passed away due to severe sepsis, and one patient was left with severe disability. Only one patient required anticoagulation and that was for a preexisting deep venous thrombosis. CONCLUSION The use of IABPs may be beneficial as an adjunctive therapy in SAH patients with concomitant symptomatic vasospasm and NSC.

Probability of IV antibiotic retreatment within thirty days is associated with duration and location of IV antibiotic treatment for pulmonary exacerbation in cystic fibrosis. J Cyst Fibros 2016; 15:783-790. [PMID: 27139161 DOI: 10.1016/j.jcf.2016.04.005] [Citation(s) in RCA: 29] [Impact Index Per Article: 3.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/04/2016] [Revised: 03/26/2016] [Accepted: 04/15/2016] [Indexed: 11/18/2022]
Abstract
BACKGROUND There are few objective data to guide management of cystic fibrosis (CF) pulmonary exacerbations. We studied intravenous (IV) antibiotic treatment failure as defined by a need to retreat patients with IV antibiotics within 30days of completion of a prior IV antibiotic treatment for pulmonary exacerbation. METHODS The first IV-treated exacerbation on or after Jan. 1, 2010 among US CF Foundation Patient Registry patients was studied, combining treatments separated by <7days into single treatments. IV treatment duration categories were: 1-4, 5-8, 9-12, 13-16, 17-22, and ≥23days (inclusive). Logistic regressions for IV retreatment in ≤30days were adjusted with 12 categorical covariates, including age, sex, lung function, prior-year exacerbations, CF complications, CF Care Program, and ever/never treated in hospital. RESULTS 777 of 13,579 patients (5.7%) were retreated within 30days, with incidence varying by treatment duration: 1-4days, 8.7%; 5-8days; 6.6%; 9-12days, 3.2%; 13-16days, 4.5%; 17-22days, 6.2%; ≥23days, 10.3% and hospitalization: ever, 5.0%; never 8.5%. Adjusted odds ratios (OR) for retreatment (compared to 13-16days treatment) were: 1-4days, 1.94 [95%CI 1.49, 2.54] P<.001; 5-8days, 1.55 [1.18, 2.04] P=.002; 9-12days, 0.78 [0.58, 1.04] P=.09; 17-22days, 1.12 [0.88, 1.42] P=.37; ≥23days, 1.46 [1.12, 1.91] P=.005. Adjusted retreatment OR for never/ever hospitalized was 1.57 [1.29, 1.90] P<.001. Prior-year exacerbation number, oxygen therapy, non-invasive ventilation, and female sex were significantly associated with retreatment. Modeling hazard rate time-dependence showed that treatment duration and location-associated hazard rates attenuated within a few months after treatment. CONCLUSION After adjustment for covariates known to be associated with increased risk of IV treatment for exacerbation, IV antibiotic treatments of <9 and ≥23days and those without hospitalization were significant risk factors for IV retreatment within 30days of completion of an exacerbation treatment.

Abstract
Abstract
OX40 is a tumor necrosis factor receptor found primarily on activated T effector (Teff) cells and regulatory T (Treg) cells including lymphocytes infiltrating mouse and human tumors. Costimulation of OX40 by agonist molecules is hypothesized to improve antitumor immunity by enhancing Teff cell activity and inhibiting Treg suppression. We conducted in vitro and in vivo experiments to characterize the costimulatory activity, assess single agent and combination antitumor efficacy and measure pharmacodynamic biomarkers of novel, agonist OX40 ligand (OX40L) fusion proteins. In vitro costimulation assays, Treg suppression studies, and human tumor/T cell xenograft mouse models were performed using MEDI6383, a human OX40L fusion protein. MEDI6383 is comprised of three distinct domains: (1) human OX40L extracellular receptor binding domains, (2) isoleucine zipper trimerization domains, and (3) human fragment crystallizable gamma (Fcγ) domains. In vivo antitumor activity was evaluated using a surrogate mouse OX40L fusion protein (mOX40L FP), and anti-mouse PD-L1, anti-mouse PD-1 or anti-mouse CTLA-4 monoclonal antibodies in multiple syngeneic mouse tumor models. MEDI6383 activated the OX40 signaling pathway, as measured by NFκB signaling, in human OX40-expressing Jurkat T reporter cells co-cultured with cells that express Fcγ receptors. With concurrent CD3 stimulation, MEDI6383 costimulated primary human Teff cells to proliferate and release cytokines, and suppressed Treg cell activity in T cell co-cultures. MEDI6383 demonstrated potent in vivo antitumor activity that was dependent on the addition of alloreactive human T cells in a mouse model of human cancer. Administration of mOX40L FP resulted in dose-dependent antitumor activity that significantly reduced growth of 4 histologically distinct mouse tumor models. Antitumor activity of mOX40L FP and increases in T-cell proliferation was dependent on the expression of activating Fcγ receptors but not the inhibitory Fcγ receptor. Checkpoint inhibitors combined with mOX40L FP resulted in significantly greater antitumor activity of established tumors than either antibody used as monotherapy. These results demonstrate that agonist OX40L fusion proteins induce potent T cell proliferation, block Treg inhibition and promote antitumor activity in preclinical models as a single agent or in combination.

When health means suffering: mammograms, pain and compassionate care. Eur J Cancer Care (Engl) 2014; 24:483-92.

Abstract
The X-ray mammogram remains the cornerstone of most public health programmes aimed at the early diagnosis of breast cancer. Its virtues of safety, reliability and cheapness maintain its established position, and Western social and cultural traditions of ambivalence to pain push any questions concerning the painfulness of the procedure into the background. As part of a larger UK/USA-based empirical study, we undertook a qualitative analysis of women's accounts of pain experienced in mammograms and their reaction to it, comparing their accounts with professional views and advice to patients as reflected in interviews, patient leaflets and practice guidelines. We found considerable variability of experience and reaction to pain among patients, and indications of similar variability in professionals' views and practice, contrasting with a uniformly reassuring message in formal institutional advice. We suggest that in practice professional work-arounds and patients' felt obligation to tolerate pain bridge this gap, but that action to tackle the problems of dropout and the emotional and operational costs of the current system is nonetheless needed. The need is for concerned groups to combine to establish a serious and sustained programme of amelioration and innovative technological development to assure more compassionate patient care and operational efficiency.

Abstract
Congenital pulmonary lymphangiectasis (CPL) is a rare vascular malformation causing dilated lymph vessels and disturbed drainage of lymph fluid. Based on the pathogenesis and clinical phenotype it can be classified as primary or secondary CPL. Associated genetic syndromes with or without lymphedema, familial occurrence and gene mutations have been described. In utero, it may present as non-immune hydrops with pleural effusions. At birth neonates may have respiratory failure due to chylothorax and pulmonary hypoplasia, causing very high short term mortality rates. Other cases may become symptomatic any time later in childhood or even during adult life. CPL is usually diagnosed based on the combination of clinical signs, imaging and histological findings. Open-lung biopsy is considered the gold standard for the diagnosis of CPL. Treatment is primarily supportive featuring aggressive mechanical ventilation and the management of problems associated with congenital chylothorax including chest-drainage, medium-chain triglycerides (MCT) diet, and octreotide.

Abstract
OX40 is a potent costimulatory receptor that can potentiate T-cell receptor signaling on the surface of T lymphocytes, leading to their activation by a specifically recognized antigen. In particular, OX40 engagement by ligands present on dendritic cells dramatically increases the proliferation, effector function, and survival of T cells. Preclinical studies have shown that OX40 agonists increase antitumor immunity and improve tumor-free survival. In this study, we performed a phase I clinical trial using a mouse monoclonal antibody (mAb) that agonizes human OX40 signaling in patients with advanced cancer. Patients treated with one course of the anti-OX40 mAb showed an acceptable toxicity profile and regression of at least one metastatic lesion in 12 of 30 patients. Mechanistically, this treatment increased T and B cell responses to reporter antigen immunizations, led to preferential upregulation of OX40 on CD4(+) FoxP3(+) regulatory T cells in tumor-infiltrating lymphocytes, and increased the antitumor reactivity of T and B cells in patients with melanoma. Our findings clinically validate OX40 as a potent immune-stimulating target for treatment in patients with cancer, providing a generalizable tool to favorably influence the antitumor properties of circulating T cells, B cells, and intratumoral regulatory T cells.
