Abstract
BACKGROUND The Translational Science Benefit Model (TSBM) was developed to broadly capture systematic measures of health and societal benefits from scientific research, beyond traditional outcome measures. We aimed to develop a systematic process for the application of the TSBM and to then provide an example of a novel application of the TSBM to an ongoing Return-to-Learn (RTL) after youth concussion project involving partnerships with community stakeholders. METHODS We invited investigators, project advisory board, and participants of the RTL project to participate in a modified Delphi process. We first generated a list of potential translational benefits using the indicators of the TSBM as guideposts. We then prioritized the benefits on an adapted Eisenhower matrix. RESULTS We invited 35 concussion care or research experts to participate, yielding 20 ranked translational benefits. Six of these recommendations were ranked high priority, six were regarded as investments, and eight were ranked as either low yield or low priority. DISCUSSION This study found that activities such as education and training of stakeholders, development of policy and consensus statements, and innovation in dissemination, were perceived as higher priority than other activities. Our approach using a modified Delphi process and incorporating the TSBM can be replicated to generate and prioritize potential benefits to society from research studies.

The impact of pre-ictal statin use on vasospasm and outcome in aneurysmal subarachnoid hemorrhage. Acta Neurochir (Wien) 2023; 165:3325-3338. [PMID: 37792050 PMCID: PMC10624707 DOI: 10.1007/s00701-023-05812-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/29/2023] [Accepted: 09/12/2023] [Indexed: 10/05/2023]
Abstract
BACKGROUND Pleiotropic effects of statins may be beneficial in alleviating cerebral vasospasm (VS) and improving outcome after aneurysmal subarachnoid hemorrhage (aSAH). Initiation of statin treatment at aSAH is not recommended; however, the effect of pre-ictal and continued statin use is not fully investigated. METHODS Retrospective study comparing aSAH patients admitted in 2012 to 2021 with pre-ictal statin use versus those not using statins. Patient entry variables, radiological/sonological VS, symptomatic VS, and radiologically documented delayed cerebral ischemia (DCI) were registered. Outcome was scored in terms of mortality, modified Rankin score, Glasgow outcome score extended, and levels of fatigue. Patients were compared on group level and in a case-control design. RESULTS We included 961 patients, with 204 (21.2%) statin users. Statin users were older and had more often hypertension. Severe radiological/sonological VS, symptomatic VS, and DCI were less frequent in statin users, and their length of stay was shorter. Mortality, functional outcome, and levels of fatigue were similar in both groups. When analyzing 89 pairs of statin users and non-statin users matched for age, aSAH severity, gender, and hypertension, we confirmed decreased radiological/sonological and symptomatic VS as well as shorter length of stay in statin users. They also had more often a favorable functional outcome and lower levels of fatigue. CONCLUSIONS Patients with pre-ictal and continued use of statins have a reduced occurrence of radiological/sonological and symptomatic VS, shorter length of stay, and more often favorable functional outcome, whereas mortality is similar to non-statin users. Even though larger multicenter studies with common, strict protocols for prevention, diagnosis, and treatment of vasospasm are needed to finally establish the value of statins in aSAH, continuation of pre-ictal statin use seems worthwhile.

Machine learning-based immune phenotypes correlate with STK11/KEAP1 co-mutations and prognosis in resectable NSCLC: a sub-study of the TNM-I trial. Ann Oncol 2023; 34:578-588. [PMID: 37100205 DOI: 10.1016/j.annonc.2023.04.005] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/05/2023] [Revised: 04/12/2023] [Accepted: 04/13/2023] [Indexed: 04/28/2023] Open
Abstract
BACKGROUND We aim to implement an immune cell score model in routine clinical practice for resected non-small-cell lung cancer (NSCLC) patients (NCT03299478). Molecular and genomic features associated with immune phenotypes in NSCLC have not been explored in detail. PATIENTS AND METHODS We developed a machine learning (ML)-based model to classify tumors into one of three categories: inflamed, altered, and desert, based on the spatial distribution of CD8+ T cells in two prospective (n = 453; TNM-I trial) and retrospective (n = 481) stage I-IIIA NSCLC surgical cohorts. NanoString assays and targeted gene panel sequencing were used to evaluate the association of gene expression and mutations with immune phenotypes. RESULTS Among the total of 934 patients, 24.4% of tumors were classified as inflamed, 51.3% as altered, and 24.3% as desert. There were significant associations between ML-derived immune phenotypes and adaptive immunity gene expression signatures. We identified a strong association of the nuclear factor-κB pathway and CD8+ T-cell exclusion through a positive enrichment in the desert phenotype. KEAP1 [odds ratio (OR) 0.27, Q = 0.02] and STK11 (OR 0.39, Q = 0.04) were significantly co-mutated in non-inflamed lung adenocarcinoma (LUAD) compared to the inflamed phenotype. In the retrospective cohort, the inflamed phenotype was an independent prognostic factor for prolonged disease-specific survival and time to recurrence (hazard ratio 0.61, P = 0.01 and 0.65, P = 0.02, respectively). CONCLUSIONS ML-based immune phenotyping by spatial distribution of T cells in resected NSCLC is able to identify patients at greater risk of disease recurrence after surgical resection. LUADs with concurrent KEAP1 and STK11 mutations are enriched for altered and desert immune phenotypes.

From a teacher and school leader perspective: What happened with smoking rules and practices during a three-year smoking preventive intervention? - Findings from the X:IT II study. EVALUATION AND PROGRAM PLANNING 2023; 97:102236. [PMID: 36645953 DOI: 10.1016/j.evalprogplan.2023.102236] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/02/2021] [Revised: 08/16/2022] [Accepted: 01/11/2023] [Indexed: 06/17/2023]
Abstract
BACKGROUND School-based smoking preventive interventions are most effective if they consist of multiple components; one of them being strict anti-smoking rules, i.e., no smoking by anyone at any location during school hours. However, there is a lack of in-depth knowledge about how smoking practices and rules about smoking actually change over time. Therefore, the purpose of this study was to examine how smoking practices changed during a three-year period in which a smoking preventive intervention with strict anti-smoking rules was implemented at schools. METHODS We used data from 46 Danish schools that were enrolled in the evaluation of the X:IT II study - a smoking preventive intervention with three main components: one of them being strict anti-smoking rules. We collected questionnaire data among school employees at four timepoints from the autumn of 2017 until April 2020. The questionnaire covered topics regarding students' and employees' tobacco patterns at the school, control with smoking, and aspects of the intervention delivery. RESULTS Over time, student smoking rules got stricter; from three out of four at baseline to almost all schools having rules about no student smoking during school hours three years later. Employee smoking rules also changed, although not as much as student rules. Overall, smoking at school grounds seemed to decline - however, student smoking at other locations increased, hence, violating the rule about no smoking during school hours. Enforcement of smoking rules also increased over time. CONCLUSION Although implementing and enforcing new rules in a school setting may be difficult, it seemed that most schools in the X:IT II study changed their rules and smoking practices for both students and employees over the three-year intervention period. It seemed, however, that students relocated their smoking to other places than the school or just outside school grounds. Implications of these findings are important to consider in future interventions, i.e., students leaving school during school hours to smoke and the physical separation between those who smoke and those who do not.

Abstract
The ability to study cancer-immune cell communication across the whole tumor section without tissue dissociation is needed, especially for cancer immunotherapy development, which requires understanding of molecular mechanisms and discovery of more druggable targets. In this work, we assembled and evaluated an integrated experimental framework and analytical process to enable genome-wide scale discovery of ligand-receptors potentially used for cellular crosstalks, followed by targeted validation. We assessed the complementarity of four different technologies: single-cell RNA sequencing and Spatial transcriptomic (measuring over >20,000 genes), RNA In Situ Hybridization (RNAscope, measuring 4-12 genes) and Opal Polaris multiplex protein staining (4-9 proteins). To utilize the multimodal data, we implemented existing methods and also developed STRISH (Spatial TRanscriptomic In Situ Hybridization), a computational method that can automatically scan across the whole tissue section for local expression of gene (e.g. RNAscope data) and/or protein markers (e.g. Polaris data) to recapitulate an interaction landscape across the whole tissue. We evaluated the approach to discover and validate cell-cell interaction in situ through in-depth analysis of two types of cancer, basal cell carcinoma and squamous cell carcinoma, which account for over 70% of cancer cases. We showed that inference of cell-cell interactions using scRNA-seq data can misdetect or detect false positive interactions. Spatial transcriptomics still suffers from misdetecting lowly expressed ligand-receptor interactions, but reduces false discovery. RNAscope and Polaris are sensitive methods for defining the location of potential ligand receptor interactions, and the STRISH program can determine the probability that local gene co-expression reflects true cell-cell interaction. We expect that the approach described here will be widely applied to discover and validate ligand receptor interaction in different types of solid cancer tumors.

Abstract
Introduction The ageing Arctic populations raise the need for work-up of cognitive function that reflects language and cultural understandings. Objectives To translate and evaluate tools for work-up of cognitive impairment in Greenland. Methods Step A: An expert panel was established to select tools suitable for the work-up of cognitive impairment at three different settings in Greenland. Step B: Tools were translated in a multiple-step process of independent translations with back-translation and adaptations by two independent translators and two Greenlandic physicians. Step C: a testing and validation process of the tools at three locations: the national hospital in the capital city; regional hospital in a town; health care centre in a small town. Results Tools selected were Mini-Cog and RUDAS. Participants for testing of tools were 43 of 61 invited, of which six had dementia. RUDAS and Mini-Cog scores were associated (p < 0.001). The smoothed AUC was 0.87 (95%-CI, 0.65–0.95) for Mini-Cog and 0.90 (95%-CI, 0.76–0.97) for RUDAS. The sensitivity of Mini-Cog with a cut-off at ≤3 was 83.3%, and specificity was 62.2%. For RUDAS with a cut-off at ≤23, these were 100% and 75.7%, respectively. Conclusions Requested tools have been translated for assessing cognitive function in the native Arctic setting. Small town residents with a Mini-Cog score of 3 or lower should be referred to a regional hospital for RUDAS, and a score of 23 or less should cause referral to the national hospital for a full work-up of cognitive function. Disclosure No significant relationships.

Abstract
UNLABELLED In this systematic review, the effects of osteoporosis patient education were examined. All studies found an effect on physical function, but for the other themes, the results were inconclusive. The findings indicate a need for further research in this topic. INTRODUCTION Osteoporosis is a chronic disease with serious consequences for the individual and major societal costs. With the aim of fracture prevention, many countries offer osteoporosis patient education. The objectives were to examine the effects and mediators of osteoporosis patient education and describe the characteristics of studies with and without an effect. Though, none of the included studies reported mediators, and therefore, we could not examine that. METHODS Six databases were searched in October 2020. Two researchers independently conducted title and abstract screening as well as full-text review. Records were included if participants had osteoporosis, and the patient education was group-based, face-to-face, and addressed two or more aspects, e.g., diet, medication, and exercise. The Cochrane Collaboration tools were used for risk of bias assessment. Finally, data were extracted into a standardized form and presented narratively. RESULTS In total, 2934 records were identified, and 13 studies met the inclusion criteria. All six studies examining the effects of patient education on physical function demonstrated improvements. In addition, one out of two RCT studies and one non-randomized study reported improved psychological wellbeing. Just one out of five RCT studies showed improvements regarding physical discomfort and disability. Effects on health-related quality of life, adherence and persistence, and knowledge of osteoporosis were inconclusive. CONCLUSION There is limited evidence for the effectiveness of osteoporosis patient education. There is a need for high-quality randomized controlled trials, which should describe the characteristics of the interventions and examine the mechanisms of osteoporosis patient education.

Abstract
BACKGROUND Tobacco control program leaders and their partners, who often present evidence to policymakers, can increase the use of evidence in program and policy development. However, up-to-date evidence from the scientific community about what works is slow to reach leaders. We describe efforts to understand and utilize tobacco control leaders' preferences for receiving evidence and report on resulting dissemination strategies, translational products, and outcomes. METHODS This work is part of the Advancing Science and Practice in the Retail Environment (ASPiRE) Center, an interdisciplinary research center focused on understanding and evaluating tobacco retail policy. Participants were members of the ASPiRE Community Advisory Board (CAB), comprised of tobacco control leaders from 30 metropolitan areas representing all regions of the US plus nine representatives from leading national tobacco control organizations (N = 39). During meetings in February 2019 and October 2020, all CAB members were invited to participate in live polls consisting of six survey questions each. Questions addressed preferences for receiving scientific evidence and their anticipated use of ASPiRE translational products. Responses were analyzed descriptively and informed translational product development and communications with ASPiRE contact list members (N = 125). ASPiRE email and website interactions were tracked from March 2019 to May 2021 as a complementary indication of content use. RESULTS Response rates for 2019 and 2020 CAB meetings were 66% (n = 26) and 59% (n = 23), respectively. CAB members indicated preferences for email communication (33%) and webinars (31%), communications once per month (46%), and short-format documents (28%). In response, the team developed translational short-format products including case studies, fact sheets, and research briefs. On average, 52% (SD = 14%) of recipients opened the newsletter and 17% (SD = 9%) clicked a link within the newsletter. Overall, 95% of responding CAB members found the products useful and all responding CAB members reported using them to communicate evidence to policymakers, staff, and coalition members. CONCLUSIONS Our successful dissemination approach to making evidence more accessible and useable for tobacco control leaders could be adapted by researchers working with community partners to assess and respond to stakeholders' preferences for receiving evidence in other areas of health policy.

Abstract
Previous studies of the prevalence of atrial fibrillation (AF) in Greenland are based on either single-point electrocardiograms (ECGs) or patients admitted with stroke. This study estimates the prevalence of AF based on disease classifications in the electronic medical record system (EMR) and prescriptions of oral anticoagulants (OACs). Patients given a diagnose classification code for AF or atrial flutter or prescribed the vitamin K antagonist Warfarin or the direct-acting oral anticoagulant Rivaroxaban were identified in the EMR. Descriptive data and selected laboratory values were extracted, and a minimum CHA2DS2-VASc score was calculated for the 790 patients identified in the EMR (66% men). A total prevalence of AF of 1.4% was found in the general population (1.8% among men and 1.0% among women), with a significantly lower prevalence among women younger than 70 years. There was a significant increase in AF-prevalence with advancing age (p<0.001) for both men and women. A minimum CHA2DS2-VASc was estimated and app. 10% of the patients may be undertreated with OACs. The prevalence of AF found in this study is higher than that found in previous studies in Greenland and comparable to the prevalence found in other Western countries, indicating that AF is common in Greenland.

Comprehensive RNA analysis of CSF reveals a role for CEACAM6 in lung cancer leptomeningeal metastases. NPJ Precis Oncol 2021; 5:90. [PMID: 34625644 PMCID: PMC8501028 DOI: 10.1038/s41698-021-00228-6] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/12/2020] [Accepted: 08/26/2021] [Indexed: 12/02/2022] Open
Abstract
Non-small cell lung cancer (NSCLC) metastatic to the brain leptomeninges is rapidly fatal, cannot be biopsied, and cancer cells in the cerebrospinal fluid (CSF) are few; therefore, available tissue samples to develop effective treatments are severely limited. This study aimed to converge single-cell RNA-seq and cell-free RNA (cfRNA) analyses to both diagnose NSCLC leptomeningeal metastases (LM), and to use gene expression profiles to understand progression mechanisms of NSCLC in the brain leptomeninges. NSCLC patients with suspected LM underwent withdrawal of CSF via lumbar puncture. Four cytology-positive CSF samples underwent single-cell capture (n = 197 cells) by microfluidic chip. Using robust principal component analyses, NSCLC LM cell gene expression was compared to immune cells. Massively parallel qPCR (9216 simultaneous reactions) on human CSF cfRNA samples compared the relative gene expression of patients with NSCLC LM (n = 14) to non-tumor controls (n = 7). The NSCLC-associated gene, CEACAM6, underwent in vitro validation in NSCLC cell lines for involvement in pathologic behaviors characteristic of LM. NSCLC LM gene expression revealed by single-cell RNA-seq was also reflected in CSF cfRNA of cytology-positive patients. Tumor-associated cfRNA (e.g., CEACAM6, MUC1) was present in NSCLC LM patients' CSF, but not in controls (CEACAM6 detection sensitivity 88.24% and specificity 100%). Cell migration in NSCLC cell lines was directly proportional to CEACAM6 expression, suggesting a role in disease progression. NSCLC-associated cfRNA is detectable in the CSF of patients with LM, and corresponds to the gene expression profile of NSCLC LM cells. CEACAM6 contributes significantly to NSCLC migration, a hallmark of LM pathophysiology.

Abstract
BACKGROUND Greenland is facing an ageing population, and little is known about the characteristics of the elderly population in Greenland. This study offers both a comparison and a description of the demographics, causes of admission, comorbidities and medication of the residents in care homes in the capital, major and minor towns in four of the five administrative regions of Greenland. METHODS The study was conducted from 2010 to 2016 as a descriptive questionnaire-based cross-sectional study. Data from eligible residents from eight care homes were collected from the regular care staff. Data were categorised into three groups based on town size for analysis. RESULTS 244 (100 %) of eligible residents participated in the study. Nearly 100 % were of Greenlandic ethnicity based on parents' place of birth, and 62 % were women. The median age at admission/study was 69/71 years for men and 77/79 years for women (both p = 0.001). The median Body Mass Index was 25.6 kg/m2, more than half of the population were previous- or never-smokers and less than ten per cent consumed more than ten drinks of alcohol per week. The most common causes of admission were dementia (25.4 %), stroke (19.3 %) and social causes (11.1 %), while stroke (30.7 %), dementia (29.5 %) and musculoskeletal diseases (25.8 %) were the most common diagnoses at the time of the study. The Barthel Index was used to estimate the residents' level of independence, and residents in smaller towns were found to have a higher level of independence than residents in the capital. The median number of prescribed medications was five, and more residents in the capital were prescribed more than ten medications than elsewhere in Greenland. CONCLUSIONS This study is the first to describe care home residents in Greenland. We found a population younger than residents in comparable Danish care homes and that women were older than men at admission. In addition, care home residents in the capital had a lower level of independence and a higher number of prescribed medications, which could relate to differences in morbidity, access to health care services and differences in social circumstances influencing the threshold for care home admission.

High expression of miR-17-5p in tumor epithelium is a predictor for poor prognosis for prostate cancer patients. Sci Rep 2021; 11:13864. [PMID: 34226620 PMCID: PMC8257715 DOI: 10.1038/s41598-021-93208-6] [Citation(s) in RCA: 17] [Impact Index Per Article: 5.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/25/2020] [Accepted: 06/15/2021] [Indexed: 02/04/2023] Open
Abstract
MicroRNAs (miRs) are small non-coding RNA molecules, which are involved in the development of various malignancies, including prostate cancer (PCa). miR-17-5p is considered the most prominent member of the miR-17-92 cluster, with an essential regulatory function of fundamental cellular processes. In many malignancies, up-regulation of miR-17-5p is associated with worse outcome. In PCa, miR-17-5p has been reported to increase cell proliferation and the risk of metastasis. In this study, prostatectomy specimens from 535 patients were collected. Tissue microarrays were constructed and in situ hybridization was performed, followed by scoring of miR-17-5p expression on different tumor compartments. High expression of miR-17-5p in tumor epithelium was associated with biochemical failure (BF, p < 0.001) and clinical failure (CF, p = 0.019). In multivariate analyses, high miR-17-5p expression in tumor epithelial cells was an independent negative prognostic factor for BF (HR 1.87, 95% CI 1.32-2.67, p < 0.001). In vitro analyses confirmed association between overexpression of miR-17-5p and proliferation, migration and invasion in prostate cancer cell lines (PC3 and DU145). In conclusion, our study suggests that a high cancer cell expression of miR-17-5p was an independent negative prognostic factor in PCa.

Abstract
Purpose In robotic-assisted partial nephrectomy (RAPN), the use of intraoperative ultrasound (IOUS) helps to localise and outline the tumours as well as the blood vessels within the kidney. The aim of this work is to evaluate the use of the pneumatically attachable flexible (PAF) rail system for US 3D reconstruction of malignant masses in RAPN. The PAF rail system is a novel device developed and previously presented by the authors to enable track-guided US scanning. Methods We present a comparison study between US 3D reconstruction of masses based on: the da Vinci Surgical System kinematics, single- and stereo-camera tracking of visual markers embedded on the probe. An US-realistic kidney phantom embedding a mass is used for testing. A new design for the US probe attachment to enhance the performance of the kinematic approach is presented. A feature extraction algorithm is proposed to detect the margins of the targeted mass in US images. Results To evaluate the performance of the investigated approaches the resulting 3D reconstructions have been compared to a CT scan of the phantom. The data collected indicates that single camera reconstruction outperformed the other approaches, reconstructing with a sub-millimetre accuracy the targeted mass. Conclusions This work demonstrates that the PAF rail system provides a reliable platform to enable accurate US 3D reconstruction of masses in RAPN procedures. The proposed system has also the potential to be employed in other surgical procedures such as hepatectomy or laparoscopic liver resection.

Abstract
OBJECTIVE Globalisation has extended to the kitchen and the Asian cuisine has gained international popularity with sushi and seaweed now being widespread. We explored the possible acute adverse effects of an iodine load from a single sushi-and-seaweed meal as seaweed iodine may induce thyroid dysfunction. METHODS Nine euthyroid participants were randomized into three groups: Halibut maki roll with either (A) newly harvested Greenlandic seaweed salad, (B) no seaweed salad on the side, or (C) Japanese seaweed salad purchased at a local store. We collected spot urine and blood samples daily for a week for measurement of iodine and creatinine in urine, thyroid stimulating hormone (TSH), and estimated-free T4 (fT4) in serum. RESULTS All participants ingested the full meal and the drop-out was nil. No adverse effects were reported. Pre-meal urinary iodine excretion (UIE) was 75 µg/g. UIE rose (p < 0.001) by 385%, 59% and 43% for groups A, B, and C, peaked in the 6-h spot urine sample at 393, 120, and 109 µg/g, and was down to pre-meal values by day 2. Serum TSH rose (p = 0.012) 150% on day 2 and was down to pre-meal values by day 3. Serum fT4 remained at the same level. No adverse reactions were reported. CONCLUSION A sushi meal increased urinary iodine excretion by 40 µg/g, or 400 µg/g if a newly harvested seaweed salad was added. An ensuing rise in serum TSH was brief, and a single sushi meal with seaweed salad did not cause any adverse events.

Lifespan data on postural balance in multiple standing positions. Gait Posture 2020; 76:68-73. [PMID: 31734637 DOI: 10.1016/j.gaitpost.2019.11.004] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/29/2019] [Revised: 10/06/2019] [Accepted: 11/06/2019] [Indexed: 02/02/2023]
Abstract
BACKGROUND Maintaining balance is important throughout life. The Nintendo Wii Balance Board (WBB) can give reliable quantitative measures of postural balance, but reference data are lacking. Furthermore, one-leg standing balance across the adult lifespan is not fully described. The aim of the study was (1) to provide reference data on postural balance in multiple standing positions using a WBB, (2) to determine an age cut-off for the ability to stand on one-leg in men and women. METHODS This was a cross-sectional study and data was collected in two cities in Denmark (Aalborg and Odense) and Norway (Oslo and Ålesund) during spring and summer of 2016. Postural balance was assessed in individuals across the adult lifespan in three different bases of support positions (hip-wide and narrow two-legged stance, and one-legged stance) using a WBB. Reference data were analyzed and presented in 10-year intervals. RESULTS A total of 354 individuals aged 20-99 years were recruited. Reference data were presented in percentiles stratified by gender for the following age categories: 20-29, 30-39, 40-49, 50-59, 60-69, 70-79, and 80+. Data showed that the difference between men and women's balance was larger at older age with men performing worst. The cut-off ability to stand on one-leg was 72.5 years without statistical evidence of gender difference. CONCLUSION This study reports reference data for postural balance across the entire adult lifespan using a WBB. More than half of the individuals over 72.5 years of age were unable to stand balanced on one-leg.

Abstract
Abstract
Leptomeningeal metastases (LM), a diffuse form of brain metastases is rare and fatal progression of non-small cell lung cancer (NSCLC). In LM, metastatic cancer cells spread and resign on the brain meninges, the cerebrospinal fluid (CSF), cranial and spinal nerves. Rapid disease progression and scarce tissue availability hinder the progress of scientific study of LM and its treatment. To overcome the critical lack of tissue and to determine the genetic profile of NSCLC LM, we have developed methods to extract tumor-associated cell-free RNA from CSF, and isolated and sequenced circulating single cells from CSF. Herein, we used high throughput qPCR to target lung and brain-associated genes and identified NSCLC LM metastases-related RNA. Brain-specific gene signature (GFAP, NRGN, SNCB, ZBTB18) was detected in all CSF sample (control and metastases), whereas lung-specific genes (MUC1, SFTPB, SFTPD, SLC34A2) were detected in CSF of brain metastases patients. Normal, healthy CSF lacks cellular component, but CSF of patients with LM metastases inhabited with very low amount of circulating tumor cells. Single cells from CSF of 4 patients with NSCLC LM metastases were captured with microfluidic chip. Cells (n = 197) were clustered by significantly differential expressed genes demonstrating two distinct populations of white blood and tumor cells. These data identified specific cfRNA and single cell transcriptome profiles compared to normal cells or patients without NSCLC LM metastases, and highlighted metastases-associated carcinoembryonic antigen-related cell adhesion molecule 6 (CEACAM6) as highly expressed in patients with NSCLC LM metastases. CEACAM6 mRNA was detected in CSF of 86% of patients with NSCLC LM but not in the CSF of control patients. In vitro inhibition of CEACAM6 protein lead to decreased invasion in NSCLC cells which was rescued by overexpression of the protein. We have developed sensitive and robust techniques to leverage human CSF to study NSCLC LM.

Abstract
Prostate cancer (PC) is a highly heterogenous disease and one of the leading causes of mortality in developed countries. Recently, studies have shown that expression of immune checkpoint proteins are directly or indirectly repressed by microRNAs (miRs) in many types of cancers. The great advantages of using miRs based therapy is the capacity of these short transcripts to target multiple molecules for the same- or different pathways with synergistic immune inhibition effects. miR-424 has previously been described as a biomarker of poor prognosis in different types of cancers. miR-424 is also found to target both the CTLA-4/CD80- and PD-1/PD-L1 axis. In the present study, the clinical significance of miR-424-3p expression in PC tissue was evaluated. Naïve radical prostatectomy specimens from 535 patients was used for tissue microarray construction. In situ hybridization was used to evaluate the expression of miR-424-3p and immunohistochemistry was used for CTLA-4 protein detection. In univariate- and multivariate analyses, low expression of miR-424-3p was significant associated with clinical failure-free survival, (p = 0.004) and p = 0.018 (HR:0.44, CI95% 0.22-0.87). Low expression of miR-424-3p also associated strongly with aggressive phenotype of PC. This highlight the importance of miR-424-3p as potential target for therapeutic treatment in prostate cancer.

Reference data on hand grip and lower limb strength using the Nintendo Wii balance board: a cross-sectional study of 354 subjects from 20 to 99 years of age. BMC Musculoskelet Disord 2019; 20:21. [PMID: 30636625 PMCID: PMC6330568 DOI: 10.1186/s12891-019-2405-7] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/19/2018] [Accepted: 01/04/2019] [Indexed: 01/11/2023] Open
Abstract
Background Accurate assessment of isometric hand grip strength (HGS) and isometric lower limb strength (LS) are often limited to specialized clinics due to high costs and need for specialized equipment and personnel. A mobile and user-friendly device would facilitate a wider use of these measures in the clinical setting. The Nintendo Wii Balance Board (WBB) is a novel and pragmatic tool that has been validated for measuring muscle strength and other clinically relevant physiological variables. However, reference data for HGS and LS are lacking. The purpose of the current study is to establish reference data for HGS and LS in individuals ≥20 years of age using the WBB method, and to characterize the effects of age in these measurements. Method Healthy participants were recruited at various locations and their HGS and LS were tested by six assessors using the WBB. Reference data were analysed and presented in age-groups, while the age-related change in HGS and LS was tested and characterized with linear regression models. Results Three hundred and fifty-four participants between 20 and 99 years of age were tested. Data are presented separately according to gender and the following age categories: 20–29, 30–39, 40–49, 50–59, 60–69, 70–79, and 80+, and presented in absolute values as well as percentiles. The main findings were; (1) Significantly higher HGS and LS among males compared to females and for the dominant limb compared to the non-dominant limb, (2) a significant decline in strength with increasing age, and (3) the rate of decline increased significantly (i.e. it was non-linear) with age for HGS, but not for LS. Conclusion This study reported reference data with percentiles for a novel method for assessing HGS and LS. Data were consistent with previously known effects of age and gender on HGS and LS. The presented data may supplement future trials using the WBB in research or in the clinical setting.

Abstract
Several ongoing clinical development programs are investigating potential disease-modifying treatments for Alzheimer's disease (AD), including lanabecestat (AZD3293/LY3314814). Lanabecestat is a brain-permeable oral inhibitor of human beta-site amyloid (Aβ) precursor protein-cleaving enzyme 1 (BACE1) that reduces Aβ production. As a potent BACE1 inhibitor, lanabecestat significantly reduced soluble Aβ species and soluble amyloid precursor proteins (sAPPβ) in mouse, guinea pig, and dog in a time- and dose-dependent manner. Significant reductions in plasma and cerebrospinal fluid (CSF) Aβ1-40 and Aβ1-42 were observed in Phase 1 studies of healthy subjects and AD patients treated with lanabecestat. Three lanabecestat trials are ongoing and intended to support registration in Early AD: (1) Phase 2/3 study in patients with mild cognitive impairment (MCI) due to AD and mild AD dementia (AMARANTH, NCT02245737); (2) Delayed-start extension study (AMARANTH-EXTENSION, NCT02972658) for patients who have completed treatment in the AMARANTH Study; and (3) Phase 3 study in mild AD dementia (DAYBREAK-ALZ, NCT02783573). This review will discuss the development of lanabecestat, results from the completed nonclinical and clinical studies, as well as describe the ongoing Phase 3 clinical trials.

Abstract
AIMS Uric acid (UA) is a risk factor for CKD. We evaluated UA in relation to change in GFR in patients with type 1 diabetes. METHODS Post hoc analysis of a trial of losartan in diabetic nephropathy, mean follow-up 3 years (IQR 1.5-3.5). UA was measured at baseline. Primary end-point was change in measured GFR. UA was tested in a linear regression model adjusted for known progression factors (gender, HbA1c, systolic blood pressure, cholesterol, baseline GFR and baseline urinary albumin excretion rate (UAER)). RESULTS Baseline UA was 0.339 mmol/l (SD ±0.107), GFR 87 ml/min/1.73 m2 (±23), geometric mean UAER 1023 mg/24 h (IQR, 631 - 1995). Mean rate of decline in GFR was 4.6 (3.7) ml/min/year. In the upper quartile of baseline UA the mean decline in GFR from baseline to the end of the study was 6.2 (4.9) ml/min/1.73 m2 and 4.1 (3.1) ml/min/1.73 m2 in the three lower quartiles of UA, (p = 0.088). In a linear model including baseline covariates (UAER, GFR, total cholesterol, HDL cholesterol) UA was associated with decline in GFR (r2 = 0.45, p < 0.001). CONCLUSION Uric acid was weakly associated with decline in GFR in type 1 diabetic patients with overt nephropathy.

Abstract
BACKGROUND Lower limb weakness is an important risk factor for fall accidents and a predictor for all-cause mortality among older adults. Unilateral whole-lower limb strength may be a better measure of fall risk than the bilateral measure. In addition, a number of clinical conditions affect only one leg, and thus this type of assessment is relevant in clinical settings. AIM To explore the intra-rater reproducibility of the Nintendo Wii Balance Board (WBB) to measure unilateral whole-lower limb strength and to compare the method with stationary isometric muscle apparatus (SID). METHOD Intra-rater test-retest design with 1 week between sessions. Thirty community-dwelling older adults (69 ± 4.2 years) were enrolled and examined for maximum lower limb strength in their dominant and non-dominant leg. Intraclass correlation coefficient (ICC) was calculated to describe relative reproducibility, while standard error of measurement (SEM), limits of agreement (LOA) and smallest real difference (SRD) were calculated to describe absolute reproducibility between test sessions. Concurrent validity with the SID was explored using the Pearson product-moment correlation coefficient (PCC). RESULTS No systematic difference was observed between test sessions. ICC was 0.919-0.950 and SEM, LOA and SRD was 2.9-4.1 kg, 24.1-28.3 kg and 7.6-11.3 kg, respectively. Further, the PCC was 0.755 and 0.730 for the dominant limb and the non-dominant limb, respectively. CONCLUSION A high relative and an acceptable absolute reproducibility was seen when using the Nintendo Wii Balance Board for testing unilateral lower limb strength in community-dwelling older adults. The WBB correlated strongly with the SID.

Abstract
Concentrations of persistent organic pollutants (POPs) are high in Inuit living predominately on the traditional marine diet. Adverse effects of POPs include disruption of the immune system and cardiovascular diseases that are frequent in Greenland Inuit. We aimed to assess the association between exposure to POPs from the marine diet and inflammation, taking into account other factors such as vitamin D. We invited Inuit and non-Inuit living in settlements or the town in rural East Greenland or in the capital city Nuuk. Participants completed a food frequency questionnaire and donated a blood sample for measurement of the two markers of inflammation YKL-40 and hsCRP, 25-hydroxy-vitamin D, eleven organochlorine pesticides (OCPs), fourteen polychlorinated biphenyls (PCBs), one polybrominated biphenyl, and nine polybrominated diphenyl ethers (PBDEs) adjusted to the serum lipid content. Participants were 50 through 69 years old, living in settlements, town or city (n = 151/173/211; 95% participation rate). ΣOCP, ΣPCB and ΣPBDE serum levels were higher in Inuit than in non-Inuit (p<0.001/ p<0.001/ p<0.001), in older individuals (p<0.001/p<0.001/p = 0.002) and in participants with the highest intake of Greenlandic food items (p<0.001/p<0.001/p<0.001). Both YKL-40 and hsCRP serum levels were higher in Inuit compared to non-Inuit (p<0.001/p = 0.001), and increased with age (p<0.001/p = 0.001) and with the intake of Greenlandic food items (p<0.001/p = 0.002). Multivariate analysis conformed to a marked influence on both YKL-40 and hsCRP by ΣOCP (p<0.001/p<0.001) and ΣPCBs (p<0.001/p = 0.001) after adjusting for age, BMI, vitamin D, alcohol and smoking. POP levels were associated with the intake of the traditional Inuit diet and with markers of inflammation. This supports a pro-inflammatory role of POPs to promote chronic diseases common to populations in Greenland. These data inform guidelines on 'the Arctic dilemma' and encourage follow-up on the ageing Arctic populations.

Abstract
Immunoscore is a prognostic tool defined to quantify in situ immune cell infiltrates and appears highly promising as a supplement to the tumor-node-metastasis (TNM) classification of various tumors. In colorectal cancer, an international task force has initiated prospective multicenter studies aiming to implement TNM-Immunoscore (TNM-I) in a routine clinical setting. In breast cancer, recommendations for the evaluation of tumor-infiltrating lymphocytes (TILs) have been proposed by an international working group. Regardless of promising results, there are potential obstacles related to implementing TNM-I into the clinic. Diverse methods may be needed for different malignancies and even within each cancer entity. Nevertheless, a uniform approach across malignancies would be advantageous. In nonsmall-cell lung cancer (NSCLC), there are several previous reports indicating an apparent prognostic importance of TILs, but studies on TILs in a TNM-I setting are sparse and no general recommendations are made. However, recently published data is promising, evoking a realistic hope of a clinical useful NSCLC TNM-I. This review will focus on the TNM-I potential in NSCLC and propose strategies for clinical implementation of a TNM-I in resected NSCLC.

Abstract
AIM The effect of insulin pump [continuous subcutaneous insulin infusion (CSII)] treatment on diabetes complications in a modern clinical setting is largely unknown. We investigated the effect of 4 years CSII treatment on HbA(1c), albuminuria and kidney function compared with multiple daily injections (MDI) in a single-centre clinical setting. METHODS All patients initiating CSII treatment from 2004 to 2010 and followed for at least 4 years were included in the study: 193 people with Type 1 diabetes were matched (1 : 2) with 386 patients treated with MDI in the same period. Matching was based on diabetes duration, gender, HbA(1c) and normo-, micro- or macroalbuminuria at baseline. Urinary albumin/creatinine ratio (UACR) was measured yearly and annual change assessed from linear regression. RESULTS CSII- vs. MDI-treated patients were comparable at baseline. After 4 years, HbA(1c) was 62 ± 11 vs. 68 ± 11 mmol/mol (7.8 ± 1.0 vs. 8.4 ± 1.0%) (P < 0.001). Annual UACR change in CSII- vs. MDI-treated patients was [mean (95% confidence interval)] -10.1 (-13.3; -6.8) vs. -1.2 (-3.6; 0.9)% (P < 0.001). Reduction in UACR was significantly associated with CSII treatment after adjustment for age, gender, diabetes duration, estimated GFR, UACR, mean arterial pressure, HbA(1c), cholesterol, renin-angiotensin-aldosterone system inhibition, anti-hypertensive treatment and smoking (P < 0.001). This remained significant (P < 0.001) when only including patients on stable renin-angiotensin-aldosterone system inhibition during follow-up (n = 465). CONCLUSIONS Treatment with CSII over 4 years independently reduced HbA(1c) and UACR compared with MDI. Reduced UACR may be due to less glycaemic variability because the effect of CSII on HbA(1c) could only partially explain the effect. This needs confirmation in randomized controlled trials.

Abstract
OBJECTIVES Inversion of the CD4:CD8 ratio is a marker of immune activation and age-associated disease. We measured the CD4:CD8 ratio as a marker of cognitive impairment in HIV-infected patients and explored differences according to clinical severity. METHODS Post hoc analysis of data from two prospective cohorts of HIV-infected patients randomly selected to undergo neuropsychological tests was performed. Test scores were adjusted for age, gender and education. Inclusion criteria were undetectable viral load and stable treatment for at least 6 months. Subjects with HIV-associated dementia were excluded. Patients were divided into an unimpaired group, a group with asymptomatic neurocognitive disorder (ANI) and a group with symptomatic HIV-associated neurocognitive disorder (sHAND), represented by mild neurocognitive disorder (MND). Demographic and background parameters, immune activation markers and the CD4:CD8 ratio were recorded. RESULTS Two hundred patients were included in the study. The mean age was 52 years, 78% were male, the mean CD4 count was 624 cells/μL, the mean nadir CD4 count was 240 cells/μL, 27% were hepatitis C virus (HCV)-coinfected, the mean duration of HIV infection was 16 years, and the mean time on current combination antiretroviral therapy (cART) was 2.9 years. Twenty-nine per cent of subjects had HAND (21% had ANI and 8% had MND). In multivariate analysis, a CD4:CD8 ratio < 1 was associated with a nadir CD4 count < 200 cells/μL [odds ratio (OR) 3.68] and with the presence of CD4(+) CD38(+) HLA(+) cells (OR 1.23). Multinominal logistic regression showed that, in comparison with the unimpaired group, diagnosis of sHAND was associated with a CD4:CD8 ratio < 1 (OR 10.62), longer HIV infection (OR 1.15) and longer current cART (OR 1.34), while the ANI group differed from the unimpaired group only for education level. CONCLUSIONS Aviraemic patients with sHAND did not display the same pattern of immune activation as subjects with ANI, suggesting that the underlying pathophysiological mechanisms could be different.

"Hearing from all sides" How legislative testimony influences state level policy-makers in the United States. Int J Health Policy Manag 2015; 4:91-8.

Abstract
BACKGROUND This paper investigates whether state legislators find testimony influential, to what extent testimony influences policy-makers' decisions, and defines the features of testimony important in affecting policy-makers' decisions. METHODS We used a mixed method approach to analyze responses from 862 state-level legislators in the United States (U.S.). Data were collected via a phone survey from January-October, 2012. Qualitative data were analyzed using a general inductive approach and codes were designed to capture the most prevalent themes. Descriptive statistics and cross tabulations were also completed on thematic and demographic data to identify additional themes. RESULTS Most legislators, regardless of political party and other common demographics, find testimony influential, albeit with various definitions of influence. While legislators reported that testimony influenced their awareness or encouraged them to take action like conducting additional research, only 6% reported that testimony changes their vote. Among those legislators who found testimony influential, characteristics of the presenter (e.g., credibility, knowledge of the subject) were the most important aspects of testimony. Legislators also noted several characteristics of testimony content as important, including use of credible, unbiased information and data. CONCLUSION Findings from this study can be used by health advocates, researchers, and individuals to fine tune the delivery of materials and messages to influence policy-makers during legislative testimony. Increasing the likelihood that information from scholars will be used by policy-makers may lead to the adoption of more health policies that are informed by scientific and practice-based evidence.

Abstract
BACKGROUND The phosphoinositide-3 kinase (PI3K) pathway is an attractive therapeutic target. However, difficulty in predicting therapeutic response limits the clinical implementation of PI3K inhibitors. This study evaluates the utility of clinically relevant magnetic resonance imaging (MRI) biomarkers for noninvasively assessing the in vivo response to the dual PI3K/mTOR inhibitor BEZ235 in two ovarian cancer models with differential PI3K pathway activity. METHODS The PI3K signalling activity of TOV-21G and TOV-112D human ovarian cancer cells was investigated in vitro. Cellular and vascular response of the xenografts to BEZ235 treatment (65 mg kg(-1), 3 days) was assessed in vivo using diffusion-weighted (DW) and dynamic contrast-enhanced (DCE)-MRI. Micro-computed tomography was performed to investigate changes in vascular morphology. RESULTS The TOV-21G cells showed higher PI3K signalling activity than TOV-112D cells in vitro and in vivo. Treated TOV-21G xenografts decreased in volume and DW-MRI revealed an increased water diffusivity that was not found in TOV-112D xenografts. Treatment-induced improvement in vascular functionality was detected with DCE-MRI in both models. Changes in vascular morphology were not found. CONCLUSIONS Our results suggest that DW- and DCE-MRI can detect cellular and vascular response to PI3K/mTOR inhibition in vivo. However, only DW-MRI could discriminate between a strong and weak response to BEZ235.
