Community organization factors affecting veteran participation in adaptive sports

Objective: This study aims to describe United States military veteran participation in adaptive sports and to assess the demographic make-up and organizational characteristics of existing adaptive sports programs.Design: Prospective, cross-sectional survey.Setting: Community organizations with adaptive sports programs.Participants: 85 adaptive sports programs.Interventions: Nine question survey.Outcome Measures: Demographic data and sports offered by adaptive sports programs in the United States.Results: The survey response rate was 70%. The median number of total participants in an organization was 75 and the median number of veterans was 50. 76% of organizations had some degree of affiliation with a VAMC. Organizations affiliated with a VAMC are more likely to be rehabilitation centers, whereas community organizations with no VAMC affiliation are most commonly independent organizations with no rehabilitation component. Individuals of all ages participate in adaptive sports, with increasing participation associated with increasing age. Golf was the sport offered most commonly by adaptive sports programs in this survey. Low-contact sports were offered more often than high-contact sports, and the majority of programs offered adaptive sports year-round.Conclusions: Our results suggest that U.S. Military veterans represent a large proportion of the individuals participating in adaptive sports. Further research specifically focusing on factors veterans find desirable when considering participating in adaptive sports is indicated to identify programs that should be promoted, developed, and funded to increase veteran participation in adaptive sports.     

Untersuchungen über die Pupillenreflexe beim Menschen

Zusammenfassung Es wird eine Methode beschrieben, die eine fortlaufende Aufzeichnung der Pupillenbewegungen beim Menschen ermöglicht.Es wird die Reaktion der Pupille auf einen kurz dauernden Lichtblitz und auf eine längerdauernde Belichtung bei verschiedenen gesunden Versuchspersonen aufgezeichnet und eingehend beschrieben.Durch gleichzeitige Registrierung an beiden Augen wird der Verlauf von konsensueller und direkter Lichtreaktion miteinander verglichen.Die Latenzzeit der Pupillenreaktion auf Licht und Verdunkelung wird bestimmt.Die Reaktion der Pupille auf Lidschlu\ wird registriert und mit dem Lichtreflex verglichen.Es wird die Konvergenzreaktion der Pupille gleichzeitig mit der Konvergenzbewegung des Auges registriert und beschrieben.

Conversion of temporary hemodialysis catheters to tunneled hemodialysis catheters

PURPOSE: To determine the feasibility and clinical outcomes of conversion of temporary to tunneled hemodialysis catheters using the same venous insertion site. METHODS: Data from 42 patients with existing temporary hemodialysis catheters referred for placement of tunneled hemodialysis catheters were retrospectively reviewed. In these patients, the temporary catheter was exchanged for a peel-away sheath, and a tunneled catheter was inserted using the existing venous access site. Technical success, procedural complications, and clinical outcomes were evaluated. Hemodialysis records were reviewed to assess catheter patency during a 30-day follow-up period. RESULTS: The study group consisted of 20 males and 22 females (mean age: 58 years). All 42 temporary catheters were successfully converted to tunneled hemodialysis catheters without immediate procedure-related complications. Follow-up data were available for 32 patients (total: 3038; median 71 catheter days). Nine catheters were removed for infection, yielding a catheter infection rate of 0.30/100 catheter days; three catheters were removed for blood flow <200 ml/min. 13 patients had catheters removed when catheters were no longer needed. Three patients died with working catheters. The patency rate was 72% at 30 days, with four catheters functioning at the end of the study period. CONCLUSION: Conversion of a temporary hemodialysis catheter to a tunneled hemodialysis catheter using the same venous insertion site is a safe procedure that avoids complications associated with venotomy and allows conservation of other central venous access sites. Patency and infection rates in these catheters are comparable to several studies of catheter exchange and de novo placement of tunneled hemodialysis catheters.     

Reactivation of codogenic endogenous retroviral (ERV) envelope genes in human endometrial carcinoma and prestages: Emergence of new molecular targets

Endometrial carcinoma (EnCa) is the most common invasive gynaecologic carcinoma. Over 85% of EnCa are classified as endometrioid, expressing steroid hormone receptors and mostly involving pathological prestages. Human endogenous retroviruses (ERV) are chromosomally integrated genes, account for about 8% of the human genome and are implicated in the etiology of carcinomas. The majority of ERV envelope (env) coding genes are either not present or not consistently represented between common gene expression microarrays. The aim of this study was to analyse the absolute gene expression of all known 21 ERV env genes including 19 codogenic and two env genes with premature stop codons in EnCa, endometrium as well as in hyperplasia and polyps. For EnCa seven env genes had high expression with >200 mol/ng cDNA (e.g. envH1-3, Syncytin-1, envT), two middle >50 mol/ng cDNA (envFc2, erv-3) and 12 low <50 mol/ng cDNA (e.g. Syncytin-2, envV2). Regarding tumor parameters, Syncytin-1 and Syncytin-2 were significantly over-expressed in advanced stage pT2 compared to pT1b. In less differentiated EnCa Syncytin-1, erv-3, envT and envFc2 were significantly over-expressed. Syncytin-1, Syncytin-2 and erv-3 were specific to glandular epithelial cells of polyps, hyperplasia and EnCa using immunohistochemistry. An analysis of 10 patient-matched EnCa with endometrium revealed that the ERV-W 5'' long terminal repeat regulating Syncytin-1 was hypomethylated, including the ERE and CRE overlapping MeCP2 sites. Functional analyses showed that 10 env genes were regulated by methylation in EnCa using the RL95-2 cell line. In conclusion, over-expressed env genes could serve as indicators for pathological pre-stages and EnCa.     

Differential regulation of mesothelial cell fibrinolysis by transforming growth factor beta 1

Management of hypertension and diabetes mellitus in primary health care requires occasional assessment of kidney function. Monitoring the urinary albumin excretion every 24?h is often used as a diagnostic gold standard but measurement of U‐Albumin concentrations in morning urine either alone or together with U‐Creatinine is a well‐established surrogate measure. We compared the ratio U‐Albumin/U‐Creatinine and U‐Albumin concentrations measured by commonly used POC (Point of care) instruments with those obtained in a central laboratory and estimated the uncertainty of the results after establishing an uncertainty budget. It is concluded that the presentation of ratios or concentrations on an ordinal scale is less satisfactory than reporting U‐Albumin concentration on a ratio scale. Moreover the latter will have the advantage of allowing the physician to adjust the diagnostic sensitivity and specificity to local needs. The present report is a methodological study and does not consider the diagnostic performance of the studied properties per se.     

New neurons in old brains

The brain was traditionally viewed as a static organ, without turnover of neurons or significant capacity for self‐repair after insults. Research in the last years has established that neurons are renewed in certain areas throughout life. The prospect of stimulation of endogenous neurogenesis as well as cell transplantation has raised hope for new therapies for neurological diseases.
