A Comparative Analysis of the Traditional Sit-and-Reach Test and the R.S. Smith Sit-and-Reach Design

Purpose: The purpose of this study is to identify the effect of the gastrocnemius on the posterior chain by comparing traditional Sit-and-Reach Test (TSRT) performance in the standard 90 degree of ankle dorsiflexion position with the R.S. Smith Sit-And-Reach Design (SSRT) placing the ankle at 35 degrees of ankle plantar flexion. Methods: The researchers tested a total of 169 participants. All participants completed an informed consent prior to the tests. After completing a five-minute elliptical warm-up, participants performed three trials of each SRT variation. The highest score of each test was recorded. The researchers used a paired t-test to determine statistical significance. Results: The participants achieved a mean distance of 24.98±9.28 cm in the TSRT and 27.83±10.10 cm in the SSRT. The results showed a significant difference between SRT performance in the standard 90 degrees of ankle dorsiflexion position and the modified ankle position of 35 degrees of ankle plantar flexion, with the significance level set at p\u3c0.001. Conclusion: The flexibility of the gastrocnemius has a significant effect on the posterior chain. Therefore, when analyzing TSRT performance, gastrocnemius flexibility must also be taken into account. Several studies have been published on the premise that the TSRT evaluates low back and hamstring flexibility. Future studies should indicate that the test is assessing low back, hamstring and gastrocnemius flexibility

Seasonality in Human Zoonotic Enteric Diseases: A Systematic Review

BACKGROUND: Although seasonality is a defining characteristic of many infectious diseases, few studies have described and compared seasonal patterns across diseases globally, impeding our understanding of putative mechanisms. Here, we review seasonal patterns across five enteric zoonotic diseases: campylobacteriosis, salmonellosis, vero-cytotoxigenic Escherichia coli (VTEC), cryptosporidiosis and giardiasis in the context of two primary drivers of seasonality: (i) environmental effects on pathogen occurrence and pathogen-host associations and (ii) population characteristics/behaviour. METHODOLOGY/PRINCIPAL FINDINGS: We systematically reviewed published literature from 1960-2010, resulting in the review of 86 studies across the five diseases. The Gini coefficient compared temporal variations in incidence across diseases and the monthly seasonality index characterised timing of seasonal peaks. Consistent seasonal patterns across transnational boundaries, albeit with regional variations was observed. The bacterial diseases all had a distinct summer peak, with identical Gini values for campylobacteriosis and salmonellosis (0.22) and a higher index for VTEC (Gini  0.36). Cryptosporidiosis displayed a bi-modal peak with spring and summer highs and the most marked temporal variation (Gini = 0.39). Giardiasis showed a relatively small summer increase and was the least variable (Gini = 0.18). CONCLUSIONS/SIGNIFICANCE: Seasonal variation in enteric zoonotic diseases is ubiquitous, with regional variations highlighting complex environment-pathogen-host interactions. Results suggest that proximal environmental influences and host population dynamics, together with distal, longer-term climatic variability could have important direct and indirect consequences for future enteric disease risk. Additional understanding of the concerted influence of these factors on disease patterns may improve assessment and prediction of enteric disease burden in temperate, developed countries

Cutaneous T‐cell lymphoma: 2017 update on diagnosis, risk‐stratification, and management

Disease overviewCutaneous T‐cell lymphomas are a heterogenous group of T‐cell lymphoproliferative disorders involving the skin, the majority of which may be classified as Mycosis Fungoides (MF) or Sézary Syndrome (SS).DiagnosisThe diagnosis of MF or SS requires the integration of clinical and histopathologic data.Risk‐adapted therapyTNMB (tumor, node, metastasis, blood) staging remains the most important prognostic factor in MF/SS and forms the basis for a “risk‐adapted,” multi‐disciplinary approach to treatment. For patients with disease limited to the skin, expectant management or skin‐directed therapies is preferred, as both disease‐specific and overall survival for these patients is favorable. In contrast, patients with advanced‐stage disease with significant nodal, visceral or blood involvement are generally approached with biologic‐response modifiers or histone deacetylase inhibitors prior to escalating therapy to include systemic, single‐agent chemotherapy. In highly‐selected patients, allogeneic stem‐cell transplantation may be considered, as this may be curative in some patients.Peer Reviewedhttps://deepblue.lib.umich.edu/bitstream/2027.42/141823/1/ajh24876.pdfhttps://deepblue.lib.umich.edu/bitstream/2027.42/141823/2/ajh24876_am.pd

Changing health behaviour with rehabilitation in thoracic cancer: a systematic review and synthesis

Objectives: International guidelines recommend that rehabilitation be offered to people with thoracic cancer to improve symptoms, function and quality of life. When rehabilitation interventions require a change in behaviour, the use of theory and behaviour change techniques (BCTs) enhance participation. Our objective was to systematically identify BCTs and examine their use in relation to the Capability,Opportunity,Motivation-Behaviour model and known enablers and barriers to engagement in this population. Method: Bibliographic databases and grey literature were searched for controlled trials of rehabilitation interventions for adults with lung cancer or mesothelioma, with no limits on language or date. Data on the application of behavioural change theory and BCTs were extracted, categorized using the BCT Taxonomy (v1) and described according to the ‘Capability, Opportunity, Motivation-Behaviour' model. Results: Twenty-seven studies of exercise (n=15) and symptom self-management (n=12) interventions were identified. Four studies reported use of behavioural change theory, one study used symptom theory. Across studies, a mean (range) of 7 (1-18) BCTs were used, representing 26 of 93 possible BCTs included in the taxonomy. Most frequent enabling BCTs were ‘instructions on how to perform behaviours' (74%), ‘behavioural practice' (74%) and ‘action planning' (70%). BCTs to address barriers were less frequent and included ‘information about health consequences' (22%), and ‘verbal persuasion about capability' (7%) to change perceptions about benefits, burden and harms. Conclusion: The application of behavioural change tools appears sub-optimal in this group of patients. Explicit use of BCTs targeting behavioural components upon which outcomes depend may improve the uptake and effectiveness of rehabilitation interventions

Comparative effectiveness and safety of non-vitamin K antagonists for atrial fibrillation in clinical practice: GLORIA-AF Registry

Background and purpose: Prospectively collected data comparing the safety and effectiveness of individual non-vitamin K antagonists (NOACs) are lacking. Our objective was to directly compare the effectiveness and safety of NOACs in patients with newly diagnosed atrial fibrillation (AF). Methods: In GLORIA-AF, a large, prospective, global registry program, consecutive patients with newly diagnosed AF were followed for 3 years. The comparative analyses for (1) dabigatran vs rivaroxaban or apixaban and (2) rivaroxaban vs apixaban were performed on propensity score (PS)-matched patient sets. Proportional hazards regression was used to estimate hazard ratios (HRs) for outcomes of interest. Results: The GLORIA-AF Phase III registry enrolled 21,300 patients between January 2014 and December 2016. Of these, 3839 were prescribed dabigatran, 4015 rivaroxaban and 4505 apixaban, with median ages of 71.0, 71.0, and 73.0 years, respectively. In the PS-matched set, the adjusted HRs and 95% confidence intervals (CIs) for dabigatran vs rivaroxaban were, for stroke: 1.27 (0.79–2.03), major bleeding 0.59 (0.40–0.88), myocardial infarction 0.68 (0.40–1.16), and all-cause death 0.86 (0.67–1.10). For the comparison of dabigatran vs apixaban, in the PS-matched set, the adjusted HRs were, for stroke 1.16 (0.76–1.78), myocardial infarction 0.84 (0.48–1.46), major bleeding 0.98 (0.63–1.52) and all-cause death 1.01 (0.79–1.29). For the comparison of rivaroxaban vs apixaban, in the PS-matched set, the adjusted HRs were, for stroke 0.78 (0.52–1.19), myocardial infarction 0.96 (0.63–1.45), major bleeding 1.54 (1.14–2.08), and all-cause death 0.97 (0.80–1.19). Conclusions: Patients treated with dabigatran had a 41% lower risk of major bleeding compared with rivaroxaban, but similar risks of stroke, MI, and death. Relative to apixaban, patients treated with dabigatran had similar risks of stroke, major bleeding, MI, and death. Rivaroxaban relative to apixaban had increased risk for major bleeding, but similar risks for stroke, MI, and death. Registration: URL: https://www.clinicaltrials.gov.

Anticoagulant selection in relation to the SAMe-TT2R2 score in patients with atrial fibrillation. the GLORIA-AF registry

Aim: The SAMe-TT2R2 score helps identify patients with atrial fibrillation (AF) likely to have poor anticoagulation control during anticoagulation with vitamin K antagonists (VKA) and those with scores >2 might be better managed with a target-specific oral anticoagulant (NOAC). We hypothesized that in clinical practice, VKAs may be prescribed less frequently to patients with AF and SAMe-TT2R2 scores >2 than to patients with lower scores. Methods and results: We analyzed the Phase III dataset of the Global Registry on Long-Term Oral Antithrombotic Treatment in Patients with Atrial Fibrillation (GLORIA-AF), a large, global, prospective global registry of patients with newly diagnosed AF and ≥1 stroke risk factor. We compared baseline clinical characteristics and antithrombotic prescriptions to determine the probability of the VKA prescription among anticoagulated patients with the baseline SAMe-TT2R2 score >2 and ≤ 2. Among 17,465 anticoagulated patients with AF, 4,828 (27.6%) patients were prescribed VKA and 12,637 (72.4%) patients an NOAC: 11,884 (68.0%) patients had SAMe-TT2R2 scores 0-2 and 5,581 (32.0%) patients had scores >2. The proportion of patients prescribed VKA was 28.0% among patients with SAMe-TT2R2 scores >2 and 27.5% in those with scores ≤2. Conclusions: The lack of a clear association between the SAMe-TT2R2 score and anticoagulant selection may be attributed to the relative efficacy and safety profiles between NOACs and VKAs as well as to the absence of trial evidence that an SAMe-TT2R2-guided strategy for the selection of the type of anticoagulation in NVAF patients has an impact on clinical outcomes of efficacy and safety. The latter hypothesis is currently being tested in a randomized controlled trial.

The Changing Landscape for Stroke\ua0Prevention in AF: Findings From the GLORIA-AF Registry Phase 2

Background GLORIA-AF (Global Registry on Long-Term Oral Antithrombotic Treatment in Patients with Atrial Fibrillation) is a prospective, global registry program describing antithrombotic treatment patterns in patients with newly diagnosed nonvalvular atrial fibrillation at risk of stroke. Phase 2 began when dabigatran, the first non\u2013vitamin K antagonist oral anticoagulant (NOAC), became available. Objectives This study sought to describe phase 2 baseline data and compare these with the pre-NOAC era collected during phase 1. Methods During phase 2, 15,641 consenting patients were enrolled (November 2011 to December 2014); 15,092 were eligible. This pre-specified cross-sectional analysis describes eligible patients\u2019 baseline characteristics. Atrial fibrillation disease characteristics, medical outcomes, and concomitant diseases and medications were collected. Data were analyzed using descriptive statistics. Results Of the total patients, 45.5% were female; median age was 71 (interquartile range: 64, 78) years. Patients were from Europe (47.1%), North America (22.5%), Asia (20.3%), Latin America (6.0%), and the Middle East/Africa (4.0%). Most had high stroke risk (CHA2DS2-VASc [Congestive heart failure, Hypertension, Age  6575 years, Diabetes mellitus, previous Stroke, Vascular disease, Age 65 to 74 years, Sex category] score  652; 86.1%); 13.9% had moderate risk (CHA2DS2-VASc = 1). Overall, 79.9% received oral anticoagulants, of whom 47.6% received NOAC and 32.3% vitamin K antagonists (VKA); 12.1% received antiplatelet agents; 7.8% received no antithrombotic treatment. For comparison, the proportion of phase 1 patients (of N = 1,063 all eligible) prescribed VKA was 32.8%, acetylsalicylic acid 41.7%, and no therapy 20.2%. In Europe in phase 2, treatment with NOAC was more common than VKA (52.3% and 37.8%, respectively); 6.0% of patients received antiplatelet treatment; and 3.8% received no antithrombotic treatment. In North America, 52.1%, 26.2%, and 14.0% of patients received NOAC, VKA, and antiplatelet drugs, respectively; 7.5% received no antithrombotic treatment. NOAC use was less common in Asia (27.7%), where 27.5% of patients received VKA, 25.0% antiplatelet drugs, and 19.8% no antithrombotic treatment. Conclusions The baseline data from GLORIA-AF phase 2 demonstrate that in newly diagnosed nonvalvular atrial fibrillation patients, NOAC have been highly adopted into practice, becoming more frequently prescribed than VKA in Europe and North America. Worldwide, however, a large proportion of patients remain undertreated, particularly in Asia and North America.
