A tiered pediatric Asthma Population Health Management Program (APHMP), based on evidence-based practices, that differentially targets populations for intervention based on rising risk for high utilization and disease complications was implemented at 6 urban and suburban practices affiliated with an academic medical center. In addition to standard pediatric asthma care, APHMP adds regular administration of the asthma control test (ACT), provider education on performance variation, and monitoring through the electronic health record-based asthma registry. As patients' use of acute health care services and complications increases, APHMP integrates multidisciplinary interventions, including an asthma coach who conducts environmental assessments in addition to addressing social needs, into their primary care. A retrospective cohort study method was used to assess population-level effects on asthma event rates and practice- and provider-level variation from 2017 to 2019. Consistent with well-documented health disparities in pediatric asthma, the analysis demonstrated that patients who were male (odds ratio [OR] = 1.21, 95% confidence interval [CI] = 1.02-1.43), 4-8 years old (OR = 4.91, 95% CI = 3.27-7.37), Spanish speaking (OR = 1.67, 95% CI = 1.54-1.81), from low-income neighborhoods (OR = 1.56, 95% CI = 1.53-2.46), and with ACT20 (OR = 2.88, 95% CI = 1.97-4.21) had higher odds of having asthma events. Six percent of patients studied were found to be at risk for high health care utilization and disease complications. Study limitations include the absence of a control group, the mixed model data collection approach, and the effects of seasonal variation on asthma events. Future directions include analyzing disease management program outcomes of incorporating an asthma coach into a patient's primary care team and addressing provider-level variation in asthma event rates.

Oral and maxillofacial surgeons frequently encounter patients who require extractions following exposure to head and neck radiation, and they must assess the risk of extraction and consider alternatives such as deliberate root retention. The purpose of this study was to determine whether dose volume would be a better predictor for osteoradionecrosis (ORN) than total dose.This is a retrospective cohort study of patients diagnosed with ORN following head and neck radiation (administered between January 2006 and December 2018) and a comparison group selected based on site and dosage who did not develop ORN. The predictor variables were total radiation dose and mandibular dose volume, and the outcome variable was ORN occurrence. Covariates included age, sex, cancer stage and site, radiation therapy type, smoking status, alcohol use, adjuvant chemotherapy use, medical comorbidities, and concomitant tumor surgery. Logistic regression models were employed and area under receiver operating characteristic curve (AUROC) and model accuracy (Acc) were used to determine the better predictor.A total of 56 patients were included in the study: 27 ORN positive (ORN+) and 29 matched controls who did not develop ORN (ORN-). Most patients were male (76.8%), considered smokers (78.6%), used alcohol (80.4%), were in stage IV (66.1%), received chemotherapy (75.0%), and received intensity modulated radiation therapy radiation (55.4%). The statistical models with V50 Gy (cc) and V65 Gy (cc) dosage variables exhibited greater predictability of ORN occurrence than total dose (AUROC: 0.90 vs 0.76 and model accuracy: 0.82 vs 0.75, respectively).The results suggest that following head and neck radiation, dose volume may be a better predictor of ORN risk than total dose. This finding is significant, both for the oral and maxillofacial surgeon who is preoperatively assessing ORN risk following radiation exposure, and for the radiation oncologist striving to minimize the risk associated with their treatment.

Cancers occur across species. Understanding what is consistent and varies across species can provide new insights into cancer initiation and evolution, with significant implications for animal welfare and wildlife conservation. We build a pan-species cancer digital pathology atlas (panspecies.ai) and conduct a pan-species study of computational comparative pathology using a supervised convolutional neural network algorithm trained on human samples. The artificial intelligence algorithm achieves high accuracy in measuring immune response through single-cell classification for two transmissible cancers (canine transmissible venereal tumour, 0.94; Tasmanian devil facial tumour disease, 0.88). In 18 other vertebrate species (mammalia = 11, reptilia = 4, aves = 2, and amphibia = 1), accuracy (range 0.57–0.94) is influenced by cell morphological similarity preserved across different taxonomic groups, tumour sites, and variations in the immune compartment. Furthermore, a spatial immune score based on artificial intelligence and spatial statistics is associated with prognosis in canine melanoma and prostate tumours. A metric, named morphospace overlap, is developed to guide veterinary pathologists towards rational deployment of this technology on new samples. This study provides the foundation and guidelines for transferring artificial intelligence technologies to veterinary pathology based on understanding of morphological conservation, which could vastly accelerate developments in veterinary medicine and comparative oncology.

To evaluate interindividual anatomical variations of the epitympanum and the usable space for implantation of active middle ear implants (AMEI) as well as the usefulness of a tablet-based software to assess individual anatomy on computed tomography (CT) scans.CT scans of 126 patients, scheduled for cochlea implantation (50.8% men; 0.6-90.0 yr) without middle ear malformations or previous middle ear surgery and with slice thickness ≤0.7 mm were analyzed.Since no standardized measurements to assess the size of the epitympanum are available, relevant distances were defined according to anatomical landmarks. Three independent raters measured these distances using a tablet-based software. Interrater correlation was computed to evaluate the quality of the measurement process. Descriptive data were analyzed for validation and for evaluation of interindividual anatomical variations. Influence of age and sex on the taken measurements was assessed.No relevant correlation between age or sex and the anatomy of the epitympanum was found. Interrater correlation ranged from Spearman's ρ = 0.3-0.9 and there were significant differences between individual rater results for various combinations. Descriptive data revealed high interindividual anatomical variance of the epitympanum, especially regarding the distance between incus and skull base.The reported descriptive data regarding the anatomy of the epitympanum emphasizes the importance of preoperative planning, especially since the height of the epitympanum showed great interindividual variance potentially limiting implantation of AMEIs. The herein used tablet-based software seems to be convenient for preoperative assessment of individual anatomy in the hand of otosurgeons.

Introduction The majority of studies evaluating the effect of myocardial injury on the survival of COVID-19 patients have been performed outside of the United States (U.S.). These studies have often utilized definitions of myocardial injury that are not guideline-based and thus, not applicable to the U.S. patient population. Methods The current study is a two-part investigation of the effect of myocardial injury on the clinical outcome of patients hospitalized with COVID-19. The first part is a retrospective analysis of 268 patients admitted to our healthcare system in Toledo, Ohio, U.S.; the second part is a systematic review and meta-analysis of all similar studies performed within the U.S. Results In our retrospective analysis, patients with myocardial injury were older (mean age 73 vs. 59 years, P 0.001), more likely to have hypertension (86% vs. 67%, P 0.005), underlying cardiovascular disease (57% vs. 24%, P 0.001), and chronic kidney disease (26% vs. 10%, P 0.004). Myocardial injury was also associated with a lower likelihood of discharge to home (35% vs. 69%, P 0.001), and a higher likelihood of death (33% vs. 10%, P 0.001), acute kidney injury (74% vs. 30%, P 0.001), and circulatory shock (33% vs. 12%, P 0.001). Our meta-analysis included 12,577 patients from 8 U.S. states and 55 hospitals who were hospitalized with COVID-19, with the finding that myocardial injury was significantly associated with increased mortality (HR 2.43, CI 2.28–3.6, P 0.0005). The prevalence of myocardial injury ranged from 9.2 to 51%, with a mean prevalence of 27.2%. Conclusion Hospitalized COVID-19 patients in the U.S. have a high prevalence of myocardial injury, which was associated with poorer survival and outcomes.

Purpose The Coronavirus Disease 2019 (COVID-19) may result not only in acute symptoms such as severe pneumonia, but also in persisting symptoms after months. Here we present a 1 year follow-up of a patient with a secondary tension pneumothorax due to COVID-19 pneumonia. Case presentation In May 2020, a 47-year-old male was admitted to the emergency department with fever, dry cough, and sore throat as well as acute chest pain and shortness of breath. Sputum testing (polymerase chain reaction, PCR) and computed tomography (CT) confirmed infection with the severe acute respiratory syndrome coronavirus type 2 (SARS-CoV-2). Eleven days after discharge, the patient returned to the emergency department with pronounced dyspnoea after coughing. CT showed a right-sided tension pneumothorax, which was relieved by a chest drain (Buelau) via mini open thoracotomy. For a period of 3 months following resolution of the pneumothorax the patient complained of fatigue with mild joint pain and dyspnoea. After 1 year, the patient did not suffer from any persisting symptoms. The pulmonary function and blood parameters were normal, with the exception of slightly increased levels of D-Dimer. The CT scan revealed only discrete ground glass opacities (GGO) and subpleural linear opacities. Conclusion Tension pneumothorax is a rare, severe complication of a SARS-CoV-2 infection but may resolve after treatment without negative long-term sequelae. Level of evidence V.

Higher optimism is associated with reduced mortality and a lower risk of age-related chronic diseases. DNA methylation (DNAm) may provide insight into mechanisms underlying these relationships. We hypothesized that DNAm would differ among older individuals who are more versus less optimistic.Using cross-sectional data from two population-based cohorts of women with diverse races/ethnicities ( n = 3816) and men (only White, n = 667), we investigated the associations of optimism with epigenome-wide leukocyte DNAm. Random-effects meta-analyses were subsequently used to pool the individual results. Significantly differentially methylated cytosine-phosphate-guanines (CpGs) were identified by the "number of independent degrees of freedom" approach: effective degrees of freedom correction using the number of principal components (PCs), explaining95% of the variation of the DNAm data (PC-correction). We performed regional analyses using comb-p and pathway analyses using the Ingenuity Pathway Analysis software.We found that essentially all CpGs (total probe N = 359,862) were homogeneous across sex and race/ethnicity in the DNAm-optimism association. In the single CpG site analyses based on homogeneous CpGs, we identified 13 significantly differentially methylated probes using PC-correction. We found four significantly differentially methylated regions and two significantly differentially methylated pathways. The annotated genes from the single CpG site and regional analyses are involved in psychiatric disorders, cardiovascular disease, cognitive impairment, and cancer. Identified pathways were related to cancer, and neurodevelopmental and neurodegenerative disorders.Our findings provide new insights into possible mechanisms underlying optimism and health.

BACKGROUND Gastric adenocarcinoma is a common malignancy, representing the third most common cause of cancer-related death globally. Most patients are initially asymptomatic, but as the cancer progresses, patients typically present with vague gastrointestinal complaints, including early satiety, heart burn, vomiting, or abdominal pain. Metastatic gastric cancer is relatively uncommon, with ~26% of patients having metastasis to a single site and 13% having metastases to multiple sites. The most common site of metastasis is the liver, followed by peritoneum, lung, and bone. CASE REPORT In this case report we describe a 73-year-old man who presented with shortness of breath, found to have large hiatal hernia along with segmental branch pulmonary embolism, bilateral pleural effusion, and diffuse interlobular septal thickening. The pleural effusion was later found to be malignant in nature and the patient was diagnosed with metastatic stage IV infiltrative gastric adenocarcinoma with metastasis to the lung and bone. Notably, the patient had no hepatic involvement. CONCLUSIONS This represents a unique case, as only 2% of malignant pleural effusions are attributable to gastric cancer. Furthermore, malignant pleural effusion is an extremely rare initial presentation of gastric adenocarcinoma, especially without liver involvement, with few existing cases documented in the literature. This case demonstrates that gastric cancer should be included on the differential diagnosis as a rare cause of pleural effusion.

BACKGROUND: The physical environmental risk factors for psychotic disorders are poorly understood. This study aimed to examine the associations between exposure to ambient air pollution, climate measures and risk of hospitalization for psychotic disorders and uncover potential disparities by demographic, community factors. METHODS: Using Health Cost and Utilization Project (HCUP) State Inpatient Databases (SIDs), we applied zero-inflated negative binomial regression to obtain relative risks of hospitalization due to psychotic disorders associated with increases in residential exposure to ambient air pollution (fine particulate matter, PM(2.5); nitrogen dioxide, NO(2)), temperature and cumulative precipitation. The analysis covered all-age residents in eight U.S. states over the period of 2002 – 2016. We additionally investigated modification by age, sex and area-level poverty, percent of blacks and Hispanics. RESULTS: Over the study period and among the covered areas, we identified 1,211,100 admissions due to psychotic disorders. For each interquartile (IQR) increase in exposure to PM(2.5) and NO(2), we observed a relative risk (RR) of 1.11 (95% confidence interval (CI) = 1.09, 1.13) and 1.27 (95% CI = 1.24, 1.31), respectively. For each 1 °C increase of temperature, the RR was 1.03 (95% CI = 1.03, 1.04). Males were more affected by NO(2). Older age residents (>= 30 yrs.) were more sensitive to PM(2.5) and temperature. Population living in economically disadvantaged areas were more affected by air pollution. CONCLUSIONS: The study suggests that living in areas with higher levels of air pollutants and ambient temperature could contribute to additional risk of inpatient care for individuals with psychotic disorders.

Objective Handgrip strength, an indicator of overall muscle strength, has been found to be associated with slower rate of cognitive decline and decreased risk for cognitive impairment and dementia. However, evaluating the replicability of associations between aging-related changes in physical and cognitive functioning is challenging due to differences in study designs and analytical models. A multiple-study coordinated analysis approach was used to generate new longitudinal results based on comparable construct-level measurements and identical statistical models and to facilitate replication and research synthesis. Methods We performed coordinated analysis on 9 cohort studies affiliated with the Integrative Analysis of Longitudinal Studies of Aging and Dementia (IALSA) research network. Bivariate linear mixed models were used to examine associations among individual differences in baseline level, rate of change, and occasion-specific variation across grip strength and indicators of cognitive function, including mental status, processing speed, attention and working memory, perceptual reasoning, verbal ability, and learning and memory. Results were summarized using meta-analysis. Results After adjustment for covariates, we found an overall moderate association between change in grip strength and change in each cognitive domain for both males and females: Average correlation coefficient was 0.55 (95% CI = 0.44–0.56). We also found a high level of heterogeneity in this association across studies. Discussion Meta-analytic results from nine longitudinal studies showed consistently positive associations between linear rates of change in grip strength and changes in cognitive functioning. Future work will benefit from the examination of individual patterns of change to understand the heterogeneity in rates of aging and health-related changes across physical and cognitive biomarkers.

ObjectiveWe tested the hypothesis that patients with a potential acute coronary syndrome (ACS) and very low levels of high-sensitivity cardiac troponin I can be efficiently and safely discharged from the emergency department after a single troponin measurement.MethodsThis prospective cohort study recruited 2255 consecutive patients aged ≥18 years presenting to the Emergency Department, Royal Perth Hospital, Western Australia, with chest pain without high-risk features but requiring the exclusion of ACS. Patients were managed using a guideline-recommended pathway or our novel Single Troponin Accelerated Triage (STAT) pathway. The primary outcome was the percentage of patients discharged in ResultsThe study enrolled 1131 patients to the standard cohort and 1124 to the STAT cohort. Thirty-eight per cent of the standard cohort were discharged directly from emergency department compared with 63% of the STAT cohort (pConclusionsAmong low-risk patients with a potential ACS, a pathway which incorporates early discharge based on a single very low level of high-sensitivity cardiac troponin increases the proportion of patients discharged directly from the emergency department, reduces length of stay and is safe.Trial registration numberACTRN12618000797279.

International audience; Spatial changes of fatty acids in the retina in response to different dietary n-3 formulations have never been explored, although a diet rich in EPA and DHA is recommended to protect the retina against the effects of aging. In this study, Wistar rats were fed for 8 weeks with balanced diet including either EPA-containing phospholipids, EPA-containing triglycerides, DHA-containing phospholipids, or DHA-containing triglycerides. Qualitative changes in fatty acid composition of plasma, erythrocytes and retina were evaluated by gas chromatography-flame ionization detector. Following the different dietary intakes, changes to the quantity and spatial organization of phosphatidylcholine (PC) and phosphatidylethanolamine (PE) species in retina were determined by liquid chromatography coupled to tandem mass spectrometry and MALDI (Matrix Assisted Laser Desorption Ionization) coupled to mass spectrometry imaging. The omega-3 content in the lipids of plasma and erythrocytes suggests that phospholipids as well as triglycerides are good omega-3 carriers for retina. However, a significant increase in DHA content in retina was observed, especially molecular species as di-DHA-containing PC and PE, as well as an increase in very long chain polyunsaturated fatty acids (VLC-PUFAs, more than 28 carbons) following phospholipid-EPA and triglyceride-DHA diets only. All supplemented diets triggered spatial organization changes of DHA in the photoreceptor layer around the optic nerve. Taken together, these findings suggest that dietary omega-3 supplementation can modify the content of fatty acids in the rat retina.

BackgroundAging-related cognitive decline is an early symptom of Alzheimer's disease and other dementias, and on its own can have substantial consequences on an individual's ability to perform important everyday functions. Despite increasing interest in the potential roles of extracellular microRNAs (miRNAs) in central nervous system (CNS) pathologies, there has been little research on extracellular miRNAs in early stages of cognitive decline. We leverage the longitudinal Normative Aging Study (NAS) cohort to investigate associations between plasma miRNAs and cognitive function among cognitively normal men.MethodsThis study includes data from up to 530 NAS participants (median age: 71.0 years) collected from 1996 to 2013, with a total of 1,331 person-visits (equal to 2,471 years of follow up). Global cognitive function was assessed using the Mini-Mental State Examination (MMSE). Plasma miRNAs were profiled using small RNA sequencing. Associations of expression of 381 miRNAs with current cognitive function and rate of change in cognitive function were assessed using linear regression (N = 457) and linear mixed models (N = 530), respectively.ResultsIn adjusted models, levels of 2 plasma miRNAs were associated with higher MMSE scores (p < 0.05). Expression of 33 plasma miRNAs was associated with rate of change in MMSE scores over time (p < 0.05). Enriched KEGG pathways for miRNAs associated with concurrent MMSE and MMSE trajectory included Hippo signaling and extracellular matrix-receptor interactions. Gene targets of miRNAs associated with MMSE trajectory were additionally associated with prion diseases and fatty acid biosynthesis.ConclusionsCirculating miRNAs were associated with both cross-sectional cognitive function and rate of change in cognitive function among cognitively normal men. Further research is needed to elucidate the potential functions of these miRNAs in the CNS and investigate relationships with other neurological outcomes.

Objectives Growing evidence supports optimism as a health asset, yet how optimism influences well-being and health remains uncertain. We evaluated 1 potential pathway—the association of optimism with daily stress processes—and tested 2 hypotheses. The stressor exposure hypothesis posits that optimism would preserve emotional well-being by limiting exposure to daily stressors. The buffering hypothesis posits that higher optimism would be associated with lower emotional reactivity to daily stressors and more effective emotional recovery from them. Methods Participants were 233 men from the Veterans Affairs Normative Aging Study who completed the Minnesota Multiphasic Personality Inventory-2 Revised Optimism–Pessimism scale in 1986/1991 and participated in up to three 8-day daily diary bursts in 2002–2010 (age at first burst: M = 76.7, SD = 6.5). Daily stressor occurrence, positive affect (PA), and negative affect (NA) were assessed nightly. We evaluated the hypotheses using multilevel structural equation models. Results Optimism was unrelated to emotional reactivity to or recovery from daily stressors. Higher optimism was associated with higher average daily PA (B = 2.31, 95% Bayesian credible interval [BCI]: 1.24, 3.38) but not NA, independent of stressor exposure. Lower stressor exposure mediated the association of higher optimism with lower daily NA (indirect effect: B = −0.27, 95% BCI: −0.50, −0.09), supporting the stressor exposure hypothesis. Discussion Findings from a sample of older men suggest that optimism may be associated with more favorable emotional well-being in later life through differences in stressor exposure rather than emotional stress response. Optimism may preserve emotional well-being among older adults by engaging emotion regulation strategies that occur relatively early in the emotion-generative process.

We report a case of itchy papulovesicular rash consistent with varicella-zoster virus reactivation after Pfizer-BioNTech vaccine second dose administration. While there have been cases of varicella-zoster virus reactivation due to COVID-19 or COVID-19 vaccine inoculation in older individuals with pre-existing conditions, this case report describes the first case of varicella-zoster virus reactivation on a healthy, young male in the absence of pre-existing conditions. The mechanisms underlying varicella-zoster virus reactivation in patients with COVID-19 are unknown and should be further characterized.

Neuromuscular scoliosis (NMS) is often associated with rapid progressive spinal deformities. Indications, when to extend the instrumentation to the pelvis for pelvic obliquity are not generally accepted at this time. This study reports on the indications, surgical technique and results using pedicle screw instrumentation exclusively with or without pelvic fixation for spine fusion in patients with NMS.Thirty-seven NMS patients were treated with pedicle screw instrumentation (PSI) between 2007 and 2013 with a minimum follow-up of 24 months. The mean age at the time of operation was 14.91 ± 2.03 years (range, 11.17-18.58). Posterior spine fusion (PSF) was conducted in 33 patients; 4 patients underwent a combined anterior spinal release followed by PSF during one-stage surgery. Pelvic fixation was achieved by ilium screws combined with S-1 screws in 4 cases and by sacral-alar-iliac (SAI) technique by Sponseller in 9 cases, respectively.The mean primary Cobb angle was 65.5° (range, 14-103°) and improved significantly to 19.8° (range, 1-50°, p 0.001) after surgery and 20.5° (range, 3-57, p = 0.47) at 2 years FU, respectively. Besides, an improvement of pelvic obliquity and T1 tilt angle could be detected. Major complications occurred in 19% and minor complications in 32%.Pedicle screw fixation only for spine fusion in patients with NMS can be applied safely with reasonable complication rates. An excellent correction in all planes, a significant improvement of the pelvic obliquity and almost no loss of correction at 2 years FU were observed.

Introduction The training of dental students and eventual practice of dentistry involves multiple components of the 'person'; therefore, understanding the personality of dental students is critical for creating a supportive student culture. Aims Our objective was to examine the personality traits of students attending Virginia Commonwealth University School of Dentistry. Methods We collected qualitative descriptive research through an anonymous survey sent to all pre-doctoral students, which included the 50-item International Personality Item Pool of the Big Five Markers (IPIP-BFM). Fifty-three dental students completed the survey. Results Analysis indicated that two of the personality traits were significantly different for both gender and academic year. The most significant deviation in scores between genders occurred for 'agreeableness and emotional stability'. Discussion The results demonstrate there may be a degree of commonality of traits shared between dental students and other professionally trained students. Nevertheless, gender-related deviations were the most remarkable findings. Conclusion Studies of personality traits have been used to consider and implement needs-based student services in other professions. The results of surveys of this kind could be considered instrumental in structuring evidence-based student services throughout the dental training curriculum, as they have been helpful for training of other professions.

OBJECTIVES To better understand and compare effects of aging and education across domains of language and cognition, we investigated whether 1) these domains show different associations with age and education, 2) these domains show similar patterns of age-related change over time, and 3) education moderates the rate of decline in these domains. METHODS We analyzed data from 306 older adults aged 55-85 at baseline of whom 116 returned for follow-up 4-8 years later. An exploratory factor analysis identified domains of language and cognition across a range of tasks. A confirmatory factor analysis analyzed cross-sectional associations of age and education with these domains. Subsequently, mixed linear models analyzed longitudinal change as a function of age and moderation by education. RESULTS Two language domains, i.e., semantic control and semantic memory efficiency, and two cognitive domains, i.e., working memory and cognitive speed, were identified. Older age negatively affected all domains, but semantic memory efficiency and higher education positively affected all domains except cognitive speed at baseline. In language domains, a steeper age-related decline was observed after age 73-74 compared to younger ages, while cognition declined linearly with age. Greater educational attainment did not protect the rate of decline over time in any domain. DISCUSSION Separate domains show varying effects of age and education at baseline, language versus cognitive domains show dissimilar patterns of age-related change over time, and education does not moderate the rate of decline in these domains. These findings broaden our understanding of age effects on cognitive and language abilities by placing observed age differences in context. Objectives: To better understand and compare effects of aging and education across domains of language and cognition, we investigated whether (a) these domains show different associations with age and education, (b) these do- mains show similar patterns of age-related change over time, and (c) education moderates the rate of decline in these domains. Method: We analyzed data from 306 older adults aged 55–85 at baseline of whom 116 returned for follow-up 4–8 years later. An exploratory factor analysis identified domains of language and cognition across a range of tasks. A confirmatory factor analysis analyzed cross-sectional associations of age and education with these domains. Subsequently, mixed linear models analyzed longitudinal change as a function of age and moderation by education. Results: We identified 2 language domains, that is, semantic control and semantic memory efficiency, and 2 cognitive domains, that is, working memory and cognitive speed. Older age negatively affected all domains except semantic memory efficiency, and higher education positively affected all domains except cognitive speed at baseline. In language domains, a steeper age-related decline was observed after age 73–74 compared to younger ages, while cognition declined linearly with age. Greater educational attainment did not protect the rate of decline over time in any domain. Discussion: Separate domains show varying effects of age and education at baseline, language versus cognitive domains show dissimilar patterns of age-related change over time, and education does not moderate the rate of decline in these domains. These findings broaden our understanding of age effects on cognitive and language abilities by placing observed age differences in context.

BACKGROUND Residual or recurrent equinus deformity is a common problem in surgically treated clubfeet. This deformity may occur due to soft tissue-related reasons or due to bony deformity. An increased anterior distal tibial angle (ADTA) was previously found in 48% of the operated clubfeet. This study aimed to determine the efficacy and safety of anterior distal tibial hemiepiphysiodesis (ADTE) in the treatment of recurrent equinus deformity in patients with an increased ADTA. METHODS Eighteen children (23 feet) treated by ADTE to correct recurrent equinus deformity in surgically treated clubfeet were included in this retrospective, single-center study. ADTE using 8 plates was performed in children with an increased ADTA (>82 degrees) and inability to dorsiflex the ankle (≤0 degree of dorsiflexion). The mean patient age was 11.3 years (range: 10.2 to 12.9 y). All patients had completed treatment with implant removal after an average of 20.3 months (range: 9 to 37 mo). RESULTS The mean preoperative ankle dorsiflexion significantly improved from -3.3 degrees (range: -20 to -0 degrees) to 6.1 degrees (range: -15 to 10 degrees) at the time of 8-plate removal (correction rate: 9.4 degrees; P

Background and Aims Conventional EMR using a hot snare is the standard of care for resection of large (≥20 mm) nonmalignant sessile colonic polyps. Serious adverse events are predominantly because of electrocautery. This could potentially be avoided by cold snare piecemeal EMR (CSP-EMR). This study aimed to evaluate the safety and efficacy of CSP-EMR of sessile colonic polyps sized ≥20 mm. Methods All cases of CSP-EMR at 5 Australian academic hospitals for sessile polyps ≥20 mm over a 2-year period, from January 2016 to December 2017, were identified retrospectively. Efficacy was defined as the absence of residual or recurrent polyp tissue during the first surveillance colonoscopy (SC1) and second surveillance colonoscopy (SC2). Clinically significant intraprocedural or delayed adverse events and surveillance colonoscopy findings were assessed by reviewing medical records. Results CSP-EMR was performed on 204 polyps sized ≥20 mm in 186 patients (men, 33.8%; median age, 68 years). SC1 for 164 polyps (80.4%) at a median interval of 150 days showed residual or recurrent polyp in 9 cases (5.5%; 95% confidence interval, 3%-11%). SC2 for 113 polyps (72.9%) at a median interval of 18 months showed late residual or recurrent polyp in 4 cases (3.5%; 95% confidence interval, .9%-8.5%) after a normal SC1. Intraprocedural bleeding was successfully treated in 4 patients (2.2%), whereas 7 patients (3.8%) experienced self-limited clinically significant post-EMR bleeding and 1 patient (.5%) required overnight observation for nonspecific abdominal pain that resolved spontaneously. None experienced other adverse events. Conclusions CSP-EMR of sessile colonic polyps ≥20 mm is technically feasible, effective, and safe. The adverse event rate and polyp recurrence rate were low. Randomized or large prospective trials are required to confirm the noninferiority and improved safety of CSP-EMR compared with conventional EMR and to further determine the polyp morphologies that are best suited for CSP-EMR.

This article views adult development through the lens of daily life experiences and recent historical changes in these experiences. In particular, it examines whether theories that postulate general linear increases in well-being throughout adulthood still hold during times of less prosperity and more uncertainty. Descriptive analyses of the National Study of Daily Experiences chart show how stress in the daily lives of Americans may have changed from the 1990s (N = 1,499) to the 2010s (N = 782). Results revealed that adults in the 2010s reported experiencing stressors on 2% more days than in the 1990s, which translates to an additional week of stressors across a year. Participants in the 2010s also reported that stressors were more severe and posed more risks to future plans and finances and that they experienced more distress. These historical changes were particularly pronounced among middle-aged adults (e.g., proportion of stressor days increased by 19%, and perceived risks to finances and to future plans rose by 61% and 52%, respectively). As a consequence, age-related linear increases in well-being observed from young adulthood to midlife in the 1990s were no longer observed in the 2010s. If further studies continue to replicate our findings, traditional theories of adult well-being that were developed and empirically tested during times of relative economic prosperity may need to be reevaluated in light of the changes in middle adulthood currently observed in this historic period.

Background Oshikhandass is a rural village in northern Pakistan where a 1989–1991 verbal autopsy study showed that diarrhea and pneumonia were the top causes of under-5 mortality. Intensive surveillance, active community health education and child health interventions were delivered in 1989–1996; here we assess improvements in under-5 mortality, diarrhea, and pneumonia over this period and 15 years later. Methods Two prospective open-cohort studies in Oshikhandass from 1989 to 1996 (Study 1) and 2011–2014 (Study 2) enrolled all children under age 60 months. Study staff trained using WHO guidelines, conducted weekly household surveillance and promoted knowledge on causes and management of diarrhea and pneumonia. Information about household characteristics and socioeconomic status was collected. Hurdle models were constructed to examine putative risk factors for diarrhea and pneumonia. Results Against a backdrop of considerable change in the socioeconomic status of the community, under-5 mortality, which declined over the course of Study 1 (from 114.3 to 79.5 deaths/1000 live births (LB) between 1989 and 1996), exceeded Sustainable Development Goal 3 by Study 2 (19.8 deaths/ 1000 LB). Reductions in diarrhea prevalence (20.3 to 2.2 days/ Child Year [CY]), incidence (2.1 to 0.5 episodes/ CY), and number of bloody diarrhea episodes (18.6 to 5.2%) seen during Study 1, were sustained in Study 2. Pneumonia incidence was 0.5 episodes /CY in Study 1 and 0.2/CY in Study 2; only 5% of episodes were categorized as severe or very severe in both studies. While no individual factors predicted a statistically significant difference in diarrhea or pneumonia episodes, the combined effect of water, toilet and housing materials was associated with a significant decrease in diarrhea; higher household income was the most protective factor for pneumonia in Study 1. Conclusions We report a 4-fold decrease in overall childhood mortality, and a 2-fold decrease in childhood morbidity from diarrhea and pneumonia in a remote rural village in Pakistan between 1989 and 2014. We conclude that significant, sustainable improvements in child health may be achieved through improved socioeconomic status and promoting interactions between locally engaged health workers and the community, but that continued efforts are needed to improve health worker training, supervision, and the rational use of medications.

Anticoagulant plasma concentrations and patient characteristics might affect the benefit–risk balance of therapy. This study assessed the impact of model-predicted rivaroxaban exposure and patient characteristics on outcomes in patients receiving rivaroxaban for venous thromboembolism treatment (VTE-T) using data from the phase 3 EINSTEIN–DVT and EINSTEIN–PE studies. In the absence of measured rivaroxaban exposure, exposure estimates were predicted based on individual increases in prothrombin time (PT) and the known correlation between rivaroxaban plasma concentrations and PT dynamics. The composite efficacy outcomes evaluated were recurrent deep-vein thrombosis (DVT) and pulmonary embolism (PE) and recurrent DVT, PE and all-cause death; safety outcomes were major bleeding and the composite of major or non-major clinically relevant (NMCR) bleeding. Exposure–response relationships were evaluated using multivariate logistic and Cox regression for the twice-daily (BID) and once-daily (OD) dosing periods, respectively. Predicted rivaroxaban exposure and CrCl were significantly associated with both efficacy outcomes in the BID period. In the OD period, exposure was significantly associated with recurrent DVT and PE but not recurrent DVT, PE and all-cause death. The statistically significant exposure–efficacy relationships were shallow. Exposure–safety relationships were absent within the investigated exposure range. During both dosing periods, low baseline hemoglobin and prior bleeding were associated with the composite of major or NMCR bleeding. In conclusion, based on the underlying data and analysis, no reliable target window for exposure with improved benefit–risk could be identified within the investigated exposure range. Therefore, monitoring rivaroxaban levels is unlikely to be beneficial in VTE-T.

Objective The purpose of this study was to determine if there is an association between Perceptual Ability Test (PAT) results and color vision deficiency (CVD). Methods Three consecutive classes of first-year dental students (n = 291) voluntarily participated in the study. The Farnsworth-Munsell 100 Hue Color Vision test (FM-100) was administered to students beneath a Macbeth Judge II viewing booth that provided ideal lighting conditions to ascertain CVD. Results of FM-100 test were recorded as total error scores (TES). Color acuity was scored as superior (TES 0-16), average (TES 20-100), or poor (TES > 100). Additional information of age, sex, ethnicity, and time to complete the FM-100 was obtained. Multiple linear regression was used to determine the association between PAT and CVD while adjusting for age, sex, ethnicity, and time to complete the FM-100 test. Results TES ranged from 0-244. There were 132 students with superior color acuity, 161 with average, and eight with poor acuity. Females performed better than males on the FM-100 test. Time to complete the FM-100 test ranged from 3:40 minutes to 25:12 minutes. There was a strong relationship between PAT scores and CVD (P = 0.0003). A 1-unit increase in PAT scores was found to result in a 9% decrease in TES; indicating that students with higher PAT scores are less likely to have CVD. Conclusion The PAT may be a preliminary screening instrument to identify students who may have CVD. The FM-100 test can then confirm the presence of CVD. Students with CVD may desire to improve dental shade matching skills through targeted training and education.

Objectives Currently, there is no optimal salvage therapy for patients with malignant pleural mesothelioma (MPM) who relapse after treatment with first-line chemotherapy. In line with the strong preclinical rationale for targeting fibroblast growth factor receptor (FGFR) signalling in malignant mesothelioma, we conducted a phase II study assessing the efficacy of AZD4547, an oral tyrosine multi-kinase FGFR 1–3 inhibitor, as a second or third-line treatment. Materials and Methods We conducted a single-center, open-label, single-arm phase II study of AZD4547 in eligible patients with confirmed, measurable MPM and radiological progression after first or second-line systemic chemotherapy. Patients received continuous, twice-daily oral AZD4547 on a 3-weekly cycle. The primary end point was 6-month progression free survival (PFS6). Response was assessed with CT scan every 6 weeks according to the modified RECIST criteria for mesothelioma (mRECIST) and toxicities were also assessed. The study used a Simon’s two-stage design: 26 patients would be recruited to the first stage and more than 7 (27 %) of 26 patients were required to achieve PFS6 to continue to stage two, for a potential total cohort of 55 patients. Results 3 of 24 patients (12 %) were progression-free at 6 months. Hence, the study fulfilled stopping criteria regardless of further recruitment and warranted discontinuation. The most common toxicities (across all grades) were hyperphosphatemia, xerostomia, mucositis, retinopathy, dysgeusia, and fatigue. Maximum toxicities were grade 2 or below for all patients across all cycles. There was no association between tumour BAP1 protein loss and clinical outcomes. Conclusions The FGFR 1–3 inhibitor AZD4547 did not demonstrate efficacy in patients with MPM who had progressed after first line treatment with platinum-based chemotherapy.

Optical coherence tomography (OCT) can detect detailed plaque features in native coronary arteries. Stent struts cause shadows that partially obscure the vessel wall, but plaque features can still be seen. We investigated the impact of stent artefact on plaque quantification and whether the plaque behind struts is associated with microvascular dysfunction.Patients retrospectively recruited from two centres, underwent OCT pre- and post-stenting on the same vessel segment. Lipid (LA) and calcium (CA) were measured as arcs. Macrophages, microchannels and cholesterol crystals were counted. Subsequently, we determined whether stented plaque features were associated with reduced Thrombolysis in Myocardial Infarction (TIMI) flow grade in consecutive patients who underwent OCT post-stenting.In 52 patients the lipid arc was similar pre- vs post-stent: median (55º [13º-93º] vs. 40º [18º-87°]; difference 1º [-7º to 16º], p = NS). Pre- and post-stent lipid were strongly correlated (r = 0.92, p 0.001). In a further 128 patients those with reduced (TIMI ≤ II) vs normal flow post percutaneous coronary intervention (PCI) showed more plaque behind struts: lipid (89º [50º-139º] vs 62º [29º-88°]; p 0.001); and calcium (24º [6º-45º] vs 7° [0º-34º]; p = 0.031). Multivariate logistic regression analysis showed that abnormal TIMI flow post-stenting was associated with diabetes (Odds ratio [OR] 2.87, CI 1.01-8.19, p = 0.048), LA (OR 1.29, 95% CI 1.14-1.38, p 0.001) and CA (OR 1.26, CI 1.07-1.40, p = 0.005).Plaque behind the struts can be accurately quantified using OCT. Furthermore, OCT plaque features in stented segments are associated with microvascular dysfunction post PCI.

The optimal upfront treatment modality for patients with nonmetastatic Gleason Score 9 and 10 prostate cancer (GS 9-10 PCa) is unknown.We conducted a retrospective cohort study of patients in the Veterans Health Administration (VHA) with GS 9-10 PCa treated with radical prostatectomy (RP) or external beam radiation therapy with androgen deprivation therapy (EBRT+ADT) from 1/2000 to 12/2010. Outcomes included overall survival (OS), distant metastasis-free survival (DMFS), and salvage/adjuvant therapy-free survival (SAFS), as assessed by Kaplan-Meier analysis.We identified 1220 veterans with GS 9-10 PCa; 335 were treated with RP, and 885 were treated with EBRT+ADT. With a median follow-up of 9.9 years, propensity score-matched analyses demonstrated that RP had superior 10-year OS (70.8% [RP] vs. 61.2% [EBRT+ADT], p 0.001), 10-year DMFS rates were similar between RP (76.7%) and EBRT+ADT (81.0%), and 10-year SAFS rates were lower for RP vs EBRT + ADT (35.2% [RP] vs. 75.2% [EBRT+ADT], p 0.001). The receipt of salvage ADT was higher with upfront RP (51.9% vs. 26.1%, p 0.001), despite receipt of adjuvant/salvage EBRT in 41.8% of RP patients. Among patients treated with RP, there were no differences in outcomes by race. However, higher survival rates were noted among Black patients treated with EBRT+ADT compared with White patients.This analysis demonstrated higher 10-year OS rates among men treated with upfront RP versus EBRT+ADT, though missing confounders and similar DMFS rates suggest the long-term cause-specific OS rates may be similar. We also highlight real-world outcomes of a diverse patient population in the VHA and improved outcomes for Black patients receiving EBRT+ADT.

Background Anxiety is linked to elevated risk of cardiometabolic disease onset, but the underlying mechanisms remain unclear. We examined the prospective association of 2 anxiety facets, neuroticism and worry, with cardiometabolic risk (CMR) trajectories for 4 decades. Methods and Results The sample comprised 1561 men from an ongoing adult male cohort. In 1975, healthy men (mean age, 53 years [SD, 8.4 years]) completed the Eysenck Personality Inventory‐Short Form neuroticism scale and a Worries Scale. Seven CMR biomarkers were assessed every 3 to 5 years. The CMR score was the number of biomarkers categorized as high‐risk based on established cut points or medication use. Using mixed effects regression, we modeled CMR trajectories over age and evaluated their associations with neuroticism and worry. Using Cox regression, we examined associations of neuroticism and worry with risk of having ≥6 CMR high‐risk biomarkers through 2015. CMR increased at 0.8 markers per decade from age 33 to 65 years, at which point men had an average of 3.8 high‐risk markers, followed by a slower increase of 0.5 markers per decade. Higher neuroticism (B=0.08; 95% CI, 0.02–0.15) and worry levels (B=0.07; 95% CI, 0.001–0.13) were associated with elevated CMR across time, and with 13% (95% CI, 1.03–1.23) and 10% (95% CI, 1.01–1.20) greater risks, respectively, of having ≥6 high‐risk CMR markers, adjusting for potential confounders. Conclusions By middle adulthood, higher anxiety levels are associated with stable differences in CMR that are maintained into older ages. Anxious individuals may experience deteriorations in cardiometabolic health earlier in life and remain on a stable trajectory of heightened risk into older ages.

Rheumatic diseases are often associated to debilitating chronic pain, which remains difficult to treat and requires new therapeutic strategies. We had previously identified lysophosphatidylcholine (LPC) in the synovial fluids from few patients and shown its effect as a positive modulator of acid-sensing ion channel 3 (ASIC3) able to induce acute cutaneous pain in rodents. However, the possible involvement of LPC in chronic joint pain remained completely unknown. Here, we show, from 2 independent cohorts of patients with painful rheumatic diseases, that the synovial fluid levels of LPC are significantly elevated, especially the LPC16:0 species, compared with postmortem control subjects. Moreover, LPC16:0 levels correlated with pain outcomes in a cohort of osteoarthritis patients. However, LPC16:0 do not appear to be the hallmark of a particular joint disease because similar levels are found in the synovial fluids of a second cohort of patients with various rheumatic diseases. The mechanism of action was next explored by developing a pathology-derived rodent model. Intra-articular injections of LPC16:0 is a triggering factor of chronic joint pain in both male and female mice, ultimately leading to persistent pain and anxiety-like behaviors. All these effects are dependent on ASIC3 channels, which drive sufficient peripheral inputs to generate spinal sensitization processes. This study brings evidences from mouse and human supporting a role for LPC16:0 via ASIC3 channels in chronic pain arising from joints, with potential implications for pain management in osteoarthritis and possibly across other rheumatic diseases.

Penetrating missile injury to the carotid arteries may lead to catastrophic hemorrhagic and/or ischemic complications. The incidence of carotid injury in patients with penetrating cervical trauma (PCT) is 11% to 13%, with most cases involving the common carotid artery (73%), followed by the internal carotid artery (ICA) (22%) and external carotid artery (5%). Approximately 50% of PCT cases result in mortality, with specific injury to the carotid arteries carrying nearly a 100% mortality rate. Although historically limited because most patients do not survive these serious injuries, treatment has become more feasible with advancements in endovascular techniques and technologies.A young man presented to our trauma center after sustaining a gunshot wound to the right neck, leading to significant hemorrhage and ultimately a Biffl grade IV ICA injury. He was taken emergently to the operating room for cervical exploration and hemostasis. A computed tomography stroke study performed after initial stabilization revealed complete right ICA occlusion with increased time-to-peak in the right hemisphere. The patient was resuscitated to maintain sufficient cerebral perfusion pressure. Later, once hemodynamic stability was achieved, the patient underwent confirmatory angiography, followed by complete ICA revascularization using a balloon guide catheter to achieve flow arrest and placement of multiple carotid stents. He made a good neurological recovery.Endovascular carotid artery revascularization may be performed successfully in the subacute phase after PCT. The use of flow arrest obtained with a balloon guide catheter assists in preventing catastrophic hemorrhage in the event of rupture.

N-terminal pro-brain natriuretic peptide (NT-proBNP) is a widely used point-of-care (POC) cardiac biomarker in human medicine. Canine NT-proBNP is used less in veterinary medicine, possibly due to the lack of a POC canine NT-proBNP assay resulting in temporal delay, increased degradation in transport, and high reported variability in the available assay. A new quantitative POC analyzer allows fast, onsite measurement of NT-proBNP, minimizing preanalytical error and reducing variability.We aimed to analytically validate an NT-proBNP assay (Vcheck) according to American Society of Veterinary Clinical Pathology (ASVCP) and Clinical Laboratory Improvement Amendments (CLIA) specifications.Archived and prospective plasma and serum samples were collected from male and female, client-owned dogs of various breeds with cardiac abnormalities (n = 81) and a healthy control population (n = 225). Precision, accuracy, analytical sensitivity, and specificity, and other statistical analyses were performed.Imprecision was considered acceptable with a coefficient of variation ranging from 9% at 4000 pmol/L to 20% at 600 pmol/L. The lower limit of quantitation was 650 pmol/L based on repetitive measures evaluation. Comparison of the Vcheck assay with the Cardiopet NT-proBNP assay revealed an excellent correlation with minimal bias when preanalytical factors were controlled. Significant degradation of NT-proBNP occurred when current methods were used at refrigerated and room temperatures, which could change diagnostic and prognostic decision-making. Age-partitioned reference intervals have high reference values of 750 pmol/L and 1280 pmol/L for juvenile and adult dogs, respectively.The Vcheck NT-ProBNP assay provides analytically acceptable results. Onsite testing can minimize variability related to preanalytical error and provide clinically useful contemporaneous results. Samples should be centrifuged immediately and analyzed within 2 hours of collection.

Breastfeeding has numerous health benefits for the mother and child. For breastfeeding to be successful and continue for longer, women need adequate support. Fathers/partners play an important role in providing this support to women, but research suggests that fathers/partners often feel inadequately informed and supported by health professionals. Midwives and health visitors are in ideal positions to offer women and their partner’s timely and relevant breastfeeding information and support throughout the perinatal period. This article discusses the benefits of breastfeeding, presents research evidence of the crucial role fathers/partners play in promoting and supporting breastfeeding, and recommends ways in which health professionals can provide breastfeeding information and support to fathers/partners.
