RESUMEN

PURPOSE: Despite the volume of accumulating knowledge from prospective Aboriginal cohort studies, longitudinal data describing developmental trajectories in health and well-being is limited. The linkage of child and carer cohorts from a historical cross-sectional survey with longitudinal health-service and social-service administrative data has created a unique and powerful data resource that underpins the Western Australian Aboriginal Child Health Survey (WAACHS) linked data study. This study aims to provide evidence-based information to Aboriginal communities across Western Australia, governments and non-government agencies on the heterogeneous life trajectories of Aboriginal children and families. PARTICIPANTS: This study comprises data from a historical cross-sectional household study of 5289 Aboriginal children from the WAACHS (2000-2002) alongside their primary (N=2113) and other (N=1040) carers, and other householders. WAACHS data were linked with Western Australia (WA) government administrative datasets up to 2020 including health, education, child protection, police and justice system contacts. The study also includes two non-Aboriginal cohorts from WA, linked with the same administrative data sources allowing comparisons of outcomes across cohorts in addition to between-group comparisons within the Aboriginal population. FINDINGS TO DATE: Linked data coverage rates are presented for all WAACHS participants. Child health outcomes for the WAACHS children (Cohort 1) are described from birth into adulthood along with other outcomes including child protection and juvenile justice involvement. FUTURE PLANS: Analysis of data from both the child and carer cohorts will seek to understand the contribution of individual, family (intergenerational) and community-level influences on Aboriginal children's developmental and health pathways, identify key developmental transitions or turning points where interventions may be most effective in improving outcomes, and compare service pathways for Aboriginal and non-Aboriginal children. All research is guided by Aboriginal governance processes and study outputs will be produced with Aboriginal leadership to guide culturally appropriate policy and practice for improving health, education and social outcomes.

RESUMEN

Substance P (SubP) and endomorphin-2 (Endo2) are co-localized presynaptically in vesicles of neurons adjacent to inspiratory rhythm-generating pre-Botzinger Complex (preBotC) neurons but the effects of co-released SubP and Endo2 on respiratory motor control are not known. To address this question, SubP alone or a combination of SubP and Endo2 (SubP/Endo2) were bath-applied in a sustained (15-min) or intermittent (5-min application, 5-min washout, x3) pattern at 10-100 nM to neonatal rat brainstem-spinal cord preparations. During neuropeptide application, SubP/Endo2 co-applications generally attenuated SubP-induced increases in burst frequency and decreases in burst amplitude. With respect to frequency plasticity (long-lasting increase in burst frequency 60 min post-neuropeptide application), SubP-induced frequency plasticity was increased with sustained SubP/Endo2 co-applications at 20 and 100 nM. Intermittent SubP/Endo2 co-applications tended to decrease the level of frequency plasticity induced by intermittent SubP alone applications. SubP/Endo2 co-applications revealed potentially new functions for neurokinin-1 (NK1R) and mu-opioid (MOR) receptors on respiratory rhythm-generating medullary neurons.

RESUMEN

INTRODUCTION: Artificial intelligence (AI) is becoming increasingly explored for its potential applications in dermatology. Among various AI models, DALL-E 2 (San Francisco, CA: OpenAI), which generates de novoimages from textual inputs, has garnered significant attention for its remarkable photorealism. In our study, we aimed to analyze the performance of DALL-E 2 in the context of dermatology. METHODS: The following 12 pediatric dermatological conditions common to ages <15 years were selected as tests: acne, atopic dermatitis, contact dermatitis, vitiligo, congenital melanocytic nevus, warts, molluscum contagiosum, seborrheic dermatitis, alopecia areata, infantile hemangioma, impetigo, and dermatophytosis, specifically tinea corporis. Representative morphological descriptions of each diagnosis, along with their corresponding names, were inputted into DALL-E 2 as textual prompts and subsequently compared. The accuracy of the generated images and their alignment with the intended descriptions were assessed. RESULTS: Among the total of 24 images reported, 18 were photorealistic and six were cartoons. More cartoons were generated when providing the model with morphological descriptions as textual inputs compared to when diagnoses were inputted. While not entirely accurate, acne stood out as the only diagnosis that was the most consistent and closest to the actual diagnosis. Both images of acne portrayed erythematous papules scattered across the face. However, DALL-E 2 resulted in poor performance for the remaining eleven diagnoses. They did not accurately represent the intended diagnoses nor align with their counterpart image. Moreover, most of the generated images featured lighter skin tones. CONCLUSION: In assessing DALL-E 2's applications in dermatology, our study highlights the need for more domain-specific and demographically inclusive training data in its algorithms to improve performance.

RESUMEN

AIM(S): To describe a sample of healthcare professionals' responses to the valid and reliable Climate and Health Tool and compare participant characteristics relating to Climate and Health Tool subscales. DESIGN: Observational, cross-sectional, multi-site study. METHODS: An electronic survey containing the Climate and Health Tool was administered to healthcare professionals across a large, multi-state health system in the Western United States with a committed effort to reducing carbon emissions. RESULTS: One thousand three hundred and sixty-three participants reported moderately elevated levels of awareness and concern around climate impacts on health and motivation to participate in climate protective actions. Respondents reported moderate levels of climate-protecting behaviours at home and low levels at work. Females were more concerned and motivated. Medical staff and respondents reporting familiarity with system environmental initiatives reported more awareness and behaviours at home to preserve climate health. CONCLUSION: Healthcare professionals are concerned and motivated to decrease climate impacts on health yet take little action at work to preserve the climate. Because of the intersection of climate change, health, and healthcare, healthcare organizations should prioritize and support meaningful action for healthcare professionals to meet community climate health needs. IMPLICATIONS FOR THE PROFESSION AND/OR PATIENT CARE: Healthcare organizations committed to contributing to climate solutions can use this research to increase healthcare professionals' education, engagement, and impact to preserve the climate and health of communities. IMPACT: Healthcare is a major contributor to carbon emissions, yet healthcare professionals' awareness, motivation, concern, and behaviours related to climate change and health were not clear. Our research showed healthcare professionals are aware and concerned about climate impacts on health but reported low levels of workplace behaviours to protect the climate. The findings of our research will impact healthcare professionals and healthcare organizations to focus efforts on climate-preserving behaviours. REPORTING METHOD: This manuscript followed the STROBE guidelines. PATIENT OR PUBLIC CONTRIBUTION: None.

RESUMEN

As part of the Anson Street African Burial Ground Project, we characterized the oral microbiomes of twelve 18th century African-descended individuals (Ancestors) from Charleston, South Carolina, USA, to study their oral health and diet. We found that their oral microbiome composition resembled that of other historic (18th-19th century) dental calculus samples but differed from that of modern samples, and was not influenced by indicators of oral health and wear observed in the dentition. Phylogenetic analysis of the oral bacteria, Tannerella forsythia and Pseudoramibacter alactolyticus, revealed varied patterns of lineage diversity and replacement in the Americas, with the Ancestors carrying strains similar to historic period Europeans and Africans. Functional profiling of metabolic pathways suggested that the Ancestors consumed a diet low in animal protein. Overall, our study reveals important insights into the oral microbial histories of African-descended individuals, particularly oral health and diet in colonial North American enslavement contexts.

RESUMEN

OBJECTIVE: Depression and anxiety are associated with poor outcomes following spine surgery. However, the influence of these conditions on achieving a minimal clinically important difference (MCID) following lumbar spine surgery, as well as the potential compounding effects of comorbid depression and anxiety, is not well understood. This study explores the impact of comorbid depression and anxiety on long-term clinical outcomes following surgical treatment for degenerative lumbar spondylolisthesis. METHODS: This study was a retrospective analysis of the multicenter, prospectively collected Quality Outcomes Database (QOD). Patients with surgically treated grade 1 lumbar spondylolisthesis from 12 centers were included. Preoperative baseline characteristics and comorbidities were recorded, including self-reported depression and/or anxiety. Pre- and postoperative patient-reported outcomes (PROs) were recorded: the numeric rating scale (NRS) score for back pain (NRS-BP), NRS score for leg pain (NRS-LP), Oswestry Disability Index (ODI), and EQ-5D. Patients were grouped into 3 cohorts: no self-reported depression or anxiety (non-SRD/A), self-reported depression or anxiety (SRD/A), or presence of both comorbidities (SRD+A). Changes in PROs over time, satisfaction rates, and rates of MCID were compared. A multivariable regression analysis was performed to establish independent associations. RESULTS: Of the 608 patients, there were 452 (74.3%) with non-SRD/A, 81 (13.3%) with SRD/A, and 75 (12.3%) with SRD+A. Overall, 91.8% and 80.4% of patients had ≥ 24 and ≥ 60 months of follow-up, respectively. Baseline PROs were universally inferior for the SRD+A cohort. However, at 60-month follow-up, changes in all PROs were greatest for the SRD+A cohort, resulting in nonsignificant differences in absolute NRS-BP, NRS-LP, ODI, and EQ-5D across the 3 groups. MCID was achieved for the SRD+A cohort at similar rates to the non-SRD/A cohort. All groups achieved > 80% satisfaction rates with surgery without significant differences across the cohorts (p = 0.79). On multivariable regression, comorbid depression and anxiety were associated with worse baseline PROs, but they had no impact on 60-month PROs or 60-month achievement of MCIDs. CONCLUSIONS: Despite lower baseline PROs, patients with comorbid depression and anxiety achieved comparable rates of MCID and satisfaction after surgery for lumbar spondylolisthesis to those without either condition. This quality-of-life benefit was durable at 5-year follow-up. These data suggest that patients with self-reported comorbid depression and anxiety should not be excluded from consideration of surgical intervention and often substantially benefit from surgery.

RESUMEN

Phaeodactylum tricornutum (PT) is a microalgae extract that contains fucoxanthin and has been shown to enhance cognitive function in younger populations. The present study assessed if PT supplementation affects cognition in healthy, young-old, physically active adults with self-perceptions of cognitive and memory decline. METHODS: Forty-three males and females (64.3 ± 6.0 years, 79.8 ± 16.0 kg, 27.0 ± 4.0 kg/m2) with perceptions of cognitive and memory decline completed the double-blind, randomized, parallel-arm, placebo-controlled intervention clinical trial. Participants were counterbalanced by sex and BMI and randomly allocated to their respective 12-week supplementation interventions, which were either the placebo (PL) or 1100 mg/day of PT containing 8.8 mg of fucoxanthin (FX). Fasting blood samples were collected, and cognitive assessments were performed during the testing session at 0, 4, and 12 weeks of intervention. The data were analyzed by multivariate and univariate general linear model (GLM) analyses with repeated measures, pairwise comparisons, and mean changes from baseline analysis with 95% confidence intervals (CIs) to assess the clinical significance of the findings. RESULTS: FX supplementation significantly affected (p < 0.05) or exhibited tendencies toward significance (p > 0.05 to p < 0.10 with effect sizes ranging from medium to large) for word recall, picture recognition reaction time, Stroop color-word test, choice reaction time, and digit vigilance test variables. Additionally, FX supplementation promoted a more consistent clinical improvement from baseline values when examining mean changes with 95% CIs, although most differences were seen over time rather than between groups. CONCLUSIONS: The results demonstrate some evidence that FX supplementation can improve working and secondary memory, vigilance, attention, accuracy, and executive function. There was also evidence that FX promoted more positive effects on insulin sensitivity and perceptions about sleep quality with no negative effects on clinical blood panels or perceived side effects. Additional research should investigate how FX may affect cognition in individuals perceiving memory and cognitive decline. Registered clinical trial #NCT05759910.

RESUMEN

Background: Bladder cancer is known to be strongly associated with smoking tobacco products. Urologists thus have an imperative role in providing smoking cessation counseling to patients to prevent the development of bladder cancer, recurrence, and other morbidities associated with smoking. Asymptomatic hematuria is often a presenting clinical symptom that warrants further investigation. This study aims to determine if smokers who have an episode of asymptomatic hematuria are more likely to quit smoking if urologists counsel them on formal smoking cessation. Methods: We completed a retrospective chart review of patients who presented for asymptomatic hematuria at our institution between January 2017 and March 2020. A total of 435 patients were identified, 134 of which were active smokers at the presentation time. We recorded smoking status at initial presentation, documentation of smoking cessation counseling, and smoking status at one year follow-up. Fischer's exact test was used for analysis. Statistical significance was set by convention at P<0.05. Results: The percentage of patients presenting with an episode of asymptomatic hematuria that quit or cut back at one year follow-up was 24.2% [95% confidence interval (CI): 13.8%, 34.7%]. In assessing the effect of formal smoking cessation counseling, 33.3% of patients with documented smoking cessation counseling quit or cut back at one year, compared to 22.8% of patients with no documented counseling. However, these findings were not statistically significant (P=0.68). Of note, smoking cessation counseling was recorded in 19 active smokers (14.2%), and 68 active smokers (50.7%) did not receive follow-up at one year. Conclusions: Smoking cessation remains a challenging endeavor for both patients and urologists. Formal counseling did not significantly contribute to quitting rates among patients, and rates of documented counseling from providers were unsubstantial. Urologists should use hematuria work-up visits as an opportunity to counsel patients on smoking cessation.

RESUMEN

OBJECTIVE: Lumbar decompression and/or fusion surgery is a common operation for symptomatic lumbar spondylolisthesis refractory to conservative management. Multiyear follow-up of patient outcomes can be difficult to obtain but allows for identification of preoperative patient characteristics associated with durable pain relief, improved functional outcome, and higher patient satisfaction. METHODS: A query of the Quality Outcomes Database (QOD) low-grade spondylolisthesis module for patients who underwent surgery for grade 1 lumbar spondylolisthesis (from July 2014 to June 2016 at the 12 highest-enrolling sites) was used to identify patient satisfaction, as measured with the North American Spine Society (NASS) questionnaire, which uses a scale of 1-4. Patients were considered satisfied if they had a score ≤ 2. Multivariable logistic regression was performed to identify baseline demographic and clinical predictors of long-term satisfaction 5 years after surgery. RESULTS: Of 573 eligible patients from a cohort of 608, patient satisfaction data were available for 81.2%. Satisfaction (NASS score of 1 or 2) was reported by 389 patients (83.7%) at 5-year follow-up. Satisfied patients were predominantly White and ambulation independent and had lower baseline BMI, lower back pain levels, lower Oswestry Disability Index (ODI) scores, and greater EQ-5D index scores at baseline when compared to the unsatisfied group. No significant differences in reoperation rates between groups were reported at 5 years. On multivariate analysis, patients who were independently ambulating at baseline had greater odds of long-term satisfaction (OR 1.12, p = 0.04). Patients who had higher 5-year ODI scores (OR 0.99, p < 0.01) and were uninsured (OR 0.43, p = 0.01) were less likely to report long-term satisfaction. CONCLUSIONS: Lumbar surgery for the treatment of grade 1 spondylolisthesis can provide lasting pain relief with high patient satisfaction. Baseline independent ambulation is associated with a higher long-term satisfaction rate after surgery. Higher ODI scores at 5-year follow-up and uninsured status are associated with lower postoperative long-term satisfaction.

RESUMEN

BACKGROUND AND PURPOSE: Mechanical thrombectomy (MT) for acute ischemic stroke (AIS) relies on efficient tracking of aspiration catheters through complex vascular anatomies. Differences in catheter design lead to variation in tracking performance which may only become apparent after use in patients. We developed an in-vitro methodology for evaluating aspiration catheter performance under a variety of pre-defined circumstances, that can be used during catheter development for design optimization. METHODS: Validation of the in-vitro methodology involved testing four large bore aspiration catheters on recreated challenging vascular access routes derived from patient angiograms. Two experienced neurointerventionalists conducted the tests under controlled physiological and procedural conditions. Each catheter design was evaluated across 30 unique anatomy-procedural set-up combinations. A fifth, prototype large bore catheter was evaluated by trained engineers to assess the applicability of the in-vitro test. RESULTS: Results from statistical analysis using a general linear model demonstrated the methodology's effectiveness in detecting significant tracking differences among catheter designs (p < 0.01). Minimal inter-operator variability was observed (p = 0.304), while procedural techniques significantly influenced tracking performance (p < 0.01). The tortuosity of the arterial access route notably impacted catheter performance (p < 0.01), with anatomical features revealing varying degrees of influence on desirable and undesirable catheter design aspects. CONCLUSION: We successfully developed a test methodology for evaluating the trackability of large bore aspiration catheters intended for treating acute ischemic stroke with large vessel occlusions. This methodology offers a robust approach to pre-clinical design assessment, utilizing anatomical models that simulate real-world vascular challenges to enhance catheter optimization.

RESUMEN

OBJECTIVE: Patients with cervical spondylotic myelopathy (CSM) experience progressive neurological impairment. Surgical intervention is often pursued to halt neurological symptom progression and allow for recovery of function. In this paper, the authors explore predictors of patient satisfaction following surgical intervention for CSM. METHODS: This is a retrospective review of prospectively collected data from the multicenter Quality Outcomes Database. Patients who underwent surgical intervention for CSM with a minimum follow-up of 2 years were included. Patient-reported satisfaction was defined as a North American Spine Society (NASS) satisfaction score of 1 or 2. Patient demographics, surgical parameters, and outcomes were assessed as related to patient satisfaction. Patient quality of life scores were measured at baseline and 24-month time points. Univariate regression analyses were performed using the chi-square test or Student t-test to assess patient satisfaction measures. Multivariate logistic regression analysis was conducted to assess for factors predictive of postoperative satisfaction at 24 months. RESULTS: A total of 1140 patients at 14 institutions with CSM who underwent surgical intervention were included, and 944 completed a patient satisfaction survey at 24 months postoperatively. The baseline modified Japanese Orthopaedic Association (mJOA) score was 12.0 ± 2.8. A total of 793 (84.0%) patients reported satisfaction (NASS score 1 or 2) after 2 years. Male and female patients reported similar satisfaction rates (female sex: 47.0% not satisfied vs 48.5% satisfied, p = 0.73). Black race was associated with less satisfaction (26.5% not satisfied vs 13.2% satisfied, p < 0.01). Baseline psychiatric comorbidities, obesity, and length of stay did not correlate with 24-month satisfaction. Crossing the cervicothoracic junction did not affect satisfactory scores (p = 0.19), and minimally invasive approaches were not associated with increased patient satisfaction (p = 0.14). Lower baseline numeric rating scale neck pain scores (5.03 vs 5.61, p = 0.04) and higher baseline mJOA scores (12.28 vs 11.66, p = 0.01) were associated with higher satisfaction rates. CONCLUSIONS: Surgical treatment of CSM results in a high rate of patient satisfaction (84.0%) at the 2-year follow-up. Patients with milder myelopathy report higher satisfaction rates, suggesting that intervention earlier in the disease process may result in greater long-term satisfaction.

RESUMEN

OBJECTIVE: Posterior lumbar interbody fusion (PLIF) and/or transforaminal lumbar interbody fusion (TLIF), referred to as "PLIF/TLIF," is a commonly performed operation for lumbar spondylolisthesis. Its long-term cost-effectiveness has not been well described. The aim of this study was to determine the 5-year cost-effectiveness of PLIF/TLIF for grade 1 degenerative lumbar spondylolisthesis using prospective data collected from the multicenter Quality Outcomes Database (QOD). METHODS: Patients enrolled in the prospective, multicenter QOD grade 1 lumbar spondylolisthesis module were included if they underwent single-stage PLIF/TLIF. EQ-5D scores at baseline, 3 months, 12 months, 24 months, 36 months, and 60 months were used to calculate gains in quality-adjusted life years (QALYs) associated with surgery relative to preoperative baseline. Healthcare-related costs associated with the index surgery and related reoperations were calculated using Medicare reimbursement-based cost estimates and validated using price transparency diagnosis-related group (DRG) charges and Medicare charge-to-cost ratios (CCRs). Cost per QALY gained over 60 months postoperatively was assessed. RESULTS: Across 12 surgical centers, 385 patients were identified. The mean patient age was 60.2 (95% CI 59.1-61.3) years, and 38% of patients were male. The reoperation rate was 5.7%. DRG 460 cost estimates were stable between our Medicare reimbursement-based models and the CCR-based model, validating the focus on Medicare reimbursement. Across the entire cohort, the mean QALY gain at 60 months postoperatively was 1.07 (95% CI 0.97-1.18), and the mean cost of PLIF/TLIF was $31,634. PLIF/TLIF was associated with a mean 60-month cost per QALY gained of $29,511. Among patients who did not undergo reoperation (n = 363), the mean 60-month QALY gain was 1.10 (95% CI 0.99-1.20), and cost per QALY gained was $27,591. Among those who underwent reoperation (n = 22), the mean 60-month QALY gain was 0.68 (95% CI 0.21-1.15), and the cost per QALY gained was $80,580. CONCLUSIONS: PLIF/TLIF for degenerative grade 1 lumbar spondylolisthesis was associated with a mean 60-month cost per QALY gained of $29,511 with Medicare fees. This is far below the well-established societal willingness-to-pay threshold of $100,000, suggesting long-term cost-effectiveness. PLIF/TLIF remains cost-effective for patients who undergo reoperation.

RESUMEN

Brown tumor due to secondary hyperparathyroidism in chronic kidney disease is a well-established entity. Brown tumor of the spine with hemorrhage causing acute neurological deficit is a rare entity. A 35-year-old gentleman, with chronic kidney disease (CKD) on dialysis, presented with acute paraplegia and loss of lower limb sensation and bowel and bladder control. Imaging revealed a T8 vertebral body expansile lytic lesion with collapse, exaggerated kyphosis, and cord compression. He underwent an emergency decompressive laminectomy and transpedicular corpectomy of T8, with posterior stabilization. Histopathology revealed lobular clusters of osteoclast-like multinucleated giant cells with background of which was possibly the reason for acute neurological deterioration in this case. Brown tumors of the spine can mimic lytic lesions of the spine like myeloma and metastasis. Suspicion must be raised given in the setting of CKD and hyperparathyroidism. They can present with hemorrhage and acute neurological deficit, which warrants urgent surgical intervention for optimal outcomes.

RESUMEN

Background Ventriculoperitoneal (VP) shunt is still a mainstay of treatment in centers for infants with aqueductal stenosis which is the most common cause of congenital obstructive hydrocephalus. Shunt migration remains a common complication. Delayed distal shunt tip migration into the thoracic cavity due to negative intrathoracic pressure is a rare occurrence. Case Presentation Authors report a 1-year-old infant presenting with drowsy sensorium, increasing head circumference, and bulging anterior fontanelle. Magnetic resonance imaging of the brain revealed significant obstructive hydrocephalus with periventricular seepage. A large expansile diverticulum of the suprapineal recess extending infratentorially compressing the dorsal midbrain and cerebellum inferiorly. The child underwent an emergency right-side VP shunt (medium pressure) in view of clinical symptoms of raised intracranial pressure. A right iliac fossa infraumbilical transverse incision was taken for placing the abdominal end. Visual confirmation of bowel was done after opening the peritoneum by two operating surgeons prior to inserting the distal catheter. Postoperative course was uneventful. The child presented 3 months later with acute dyspnea and diminished breath sounds on the right hemithorax. Neurologically, the child was active, feeding well, and anterior fontanelle was lax. A chest roentgenogram and computed tomogram (CT) of the thorax revealed complete shunt migration into the pleural space with significant pleural effusion on the right side. The distal shunt system on CT appeared to enter the pleural space below the 8th rib, probably indicating that there was subcostal tunneling of the shunt below the 8th rib space during the first surgery which was inconspicuous and subsequently over a span of 3 months due to sucking effect of negative intrathoracic pressure the shunt gradually migrated into the pleural cavity which led to the effusion. An emergency VP shunt revision was performed. The distal end below the chamber was retunneled subcutaneously into a new incision in the left paraumbilical region. Postoperative chest and abdomen roentgenograms showed resolving effusion and accurate shunt placement. The child required elective ventilation temporarily to tide over the underlying lung collapse and an intercostal tube drainage for the cerebrospinal fluid (CSF) hydrothorax for 2 days to aid in quicker weaning. The child was discharged on the 5th postoperative day. Discussion Intrapleural migration of VP shunts has been contemplated to be due to trauma during surgery, migration across foramen of Bochdalek or Morgagni, and negative intrathoracic pressure. Taub and Lavyne have classified thoracic complications of VP shunt as thoracic trauma during shunt tunneling, supradiaphragmatic migration of shunt or transdiaphragmatic migration of shunt, and pleural effusion complicated by CSF ascites. Transdiaphragmatic migration is commonly seen in pediatric population and supradiaphragmatic migration can be seen in any age group. We believe our case to be a type of supradiaphragmatic migration of the shunt which has occurred slowly over a span of time due to the negative intrathoracic pressure. The idea behind this clinical case image is to edify neurosurgeons, pediatricians, and intensivists to remain wary of such a complication.

RESUMEN

BACKGROUND: Glioblastoma patients may develop functional deficits post-operatively that affect activities of daily living and result in worse outcomes. The Activity Measure for Post-Acute Care (AM-PAC) instrument assigns patients basic mobility and daily activity scores, but it is unknown if these scores correlate with post-operative outcomes in glioblastoma patients. METHODS: Adult (≥18 years) glioblastoma patients evaluated by physical/occupational therapy after resection at a single instution (June 2008-December 2020) were identified. Patient demographics, post-operative AM-PAC scores, and clinical outcomes were collected. Multivariate regression identified associations between AM-PAC scores and post-operative outcomes. RESULTS: 600 patients were included (mean age 59.3 years, 59.2 % male); 151 (25.3 %) and 246 (43.8 %) patients had low mobility (<42.9) and activity (<39.4) scores, respectively. 103 (17.2 %) and 177 (29.5 %) patients experienced extended lengths of stay (LOS) in the ICU (≥2 days) and overall (≥7 days), respectively. 154 (25.7 %) patients had non-home discharges. The 30-day readmission rate was 13.7 %. In multivariate analysis, low mobility scores correlated with increased odds of extended overall (p < 0.0001) and ICU (p = 0.0004) LOS, non-home discharge (p < 0.0001), and 30-day readmission (p = 0.0405). Low activity scores correlated with extended overall LOS (<0.0001) and non-home discharge (p < 0.0001). In log-rank analysis, median survival time was shorter for patients with low mobility (9.5 vs. 14.7 months, p < 0.0001) and activity (10.6 vs. 16.3 months, p < 0.0001) scores than for high-scoring patients. CONCLUSION: AM-PAC basic mobility and daily activity scores are associated with outcomes after glioblastoma resection. These easily obtainable scores may be useful for prognosticating and guiding decision making in post-operative glioblastoma patients.

RESUMEN

Mars has been exposed to ionizing radiation for several billion years, and as part of the search for life on the Red Planet, it is crucial to understand the impact of radiation on biosignature preservation. Several NASA and ESA missions are looking for evidence of ancient life in samples collected at depths shallow enough that they have been impacted by galactic cosmic rays (GCRs). In this study, we exposed a diverse set of Mars analog samples to 0.9 Megagray (MGy) of gamma radiation to mimic 15 million years of exposure on the Martian surface. We measured no significant impact of GCRs on the total organic carbon (TOC) and bulk stable C isotopes in samples with initial TOC concentration > 0.1 wt. %; however, diagnostic molecular biosignatures presented a wide range of degradation that didn't correlate to factors like mineralogy, TOC, water content, and surface area. Exposure dating suggests that the surface of Gale crater has been irradiated at more than five times our dose, yet using this relatively low dose and "best-case scenario" geologically recalcitrant biomarkers, large and variable losses were nevertheless evident. Our results empasize the importance of selecting sampling sites at depth or recently exposed at the Martian surface.

RESUMEN

BACKGROUND: Although 6-month follow-up of patients with multisystem inflammatory syndrome in children (MIS-C) was reassuring, there is scant data on long-term sequelae, including whether changing variants affect clinical severity and outcomes. METHODS: Children (<18 years of age) admitted to Great Ormond Street Hospital between April 4, 2020, and January 2023, meeting diagnostic criteria for MIS-C were included. Admission and follow-up data were categorized by the predominant SARS-CoV-2 circulating variant in the United Kingdom. RESULTS: One hundred and sixty children [median age, 10.1 (interquartile range, 7.9-12.6) years] were included. There was no difference in the time of symptom onset to diagnosis between waves ( P =0.23) or hospitalization days across all waves ( P =0.32). Inflammatory markers were normal for up to 2 years in all patients except one. Eleven patients (6.9%) remain in follow-up: cardiology (n=5), gastroenterology (n=5) and nephrology (n=1). The main self-reported symptoms at 2 years were abdominal pain (n=5) and myalgia (n=2). Fatigue was present in approximately a quarter of patients at admission; this reduced to 14 (9%), (2%) and 1 (2%) at 6-month, 1-year and 2-year follow-ups, respectively. Chronic fatigue or long-COVID symptomatology was rare (n=1) even with high rates of concurrent Epstein-Barr virus positivity (49/134). All patients had sustained neurological recovery with no new neurological pathology observed. CONCLUSIONS: Patients with MIS-C have a sustained recovery, which is reassuring for positive long-term outcomes. Across waves, time from symptom onset to diagnosis and treatment, symptomatology and length of stay were similar. Sustained recovery is reassuring for clinicians and parents alike. Differentiating long-COVID symptomatology from that of MIS-C is important in formulating an individualized treatment plan.

RESUMEN

BACKGROUND: Ashwagandha has been reported to reduce stress and attenuate cognitive decline associated with inflammation and neurodegeneration in clinical populations. However, the effects as a potential nootropic nutrient in younger populations are unclear. This study examined the effects of liposomal ashwagandha supplementation on cognitive function, mood, and markers of health and safety in healthy young men and women. METHODS: 59 men and women (22.7 ± 7 yrs., 74.9 ± 16 kg, 26.2 ± 5 BMI) fasted for 12 h, donated a fasting blood sample, and were administered the COMPASS cognitive function test battery (Word Recall, Word recognition, Choice Reaction Time Task, Picture Recognition, Digit Vigilance Task, Corsi Block test, Stroop test) and profile of mood states (POMS). In a randomized and double-blind manner, participants were administered 225 mg of a placebo (Gum Arabic) or ashwagandha (Withania somnifera) root and leaf extract coated with a liposomal covering. After 60-min, participants repeated cognitive assessments. Participants continued supplementation (225 mg/d) for 30 days and then returned to the lab to repeat the experiment. Data were analyzed using a general linear model (GLM) univariate analysis with repeated measures and pairwise comparisons of mean changes from baseline with 95% confidence intervals (CI). RESULTS: Ashwagandha supplementation improved acute and/or 30-day measures of Word Recall (correct and recalled attempts), Choice Reaction Time (targets identified), Picture Recognition ("yes" correct responses, correct and overall reaction time), Digit Vigilance (correct reaction time), Stroop Color-Word (congruent words identified, reaction time), and POMS (tension and fatigue) from baseline more consistently with several differences observed between groups. CONCLUSION: Results support contentions that ashwagandha supplementation (225 mg) may improve some measures of memory, attention, vigilance, attention, and executive function while decreasing perceptions of tension and fatigue in younger healthy individuals.
