TL;DR: The ultrastructure score of skin biopsy has predictive value for the diagnosis of vEDS, and addition of these three items (defining an ultrast structure score) had the best diagnosis value.
Abstract: Vascular Ehlers–Danlos syndrome (vEDS) results from a mutation in the gene encoding alpha-1, type III pro-collagen (COL3A1) and confers fragility to skin, ligament and vascular tissue. We tested the value of skin biopsy for diagnosis of vEDS through an ultrastructure scoring procedure. Study design was a multicentric, case–control, blinded trial consisting of two phases: phase 1 was to identify an ultra-structure score providing the best discriminative value for vEDS and phase 2 was to replicate this result in a different population. We enrolled 103 patients, 66 cases defined through the revised nosology for Ehlers–Danlos syndromes and 37 control subjects selected from patients referred for other pathologies. Ultrastructure of extracellular matrix was read by three to five experienced pathologists blinded for diagnosis. We used the receiver operating curves and logistic regression analysis for ranking ultrastructure scores. We created a detailed description of lesions observed in vEDS patients with 27 items (coded 0 or 1). In the phase 1 (17 cases and 20 controls), abnormal fibroblast shape, presence of lysosomes in the fibroblast and abnormal basal lamina were found to be independent discriminative items. Addition of these three items (defining an ultrastructure score) had the best diagnosis value (area under the curve (AUC) = 0.96). In the phase 2 (49 cases, 17 controls), ultrastructure score provided odds ratio of 9.76 (95 % CI 2.91–32.78), and AUC of 0.90. The ultrastructure score of skin biopsy has predictive value for the diagnosis of vEDS. Presence of two or more signs (either abnormal fibroblast, presence of lysosomes in the fibroblast or abnormal basal lamina) is very evocative of vEDS.

TL;DR: In this article, a cross-sectional analysis of 8649 adults aged 50 to 75 years was conducted to determine the association between occupational, sport, leisure, and total PA with baroreflex sensitivity (BRS), distinguishing between neural and mechanical BRS.
Abstract: Physical activity (PA) is a preventative behavior for noncommunicable disease. However, little consideration is given as to whether different domains of PA have differing associations with health outcomes. We sought to determine the association between occupational, sport, leisure, and total PA with baroreflex sensitivity (BRS), distinguishing between neural (nBRS) and mechanical (mBRS) BRS. In a cross-sectional analysis of 8649 adults aged 50 to 75 years, resting nBRS (estimated by low-frequency gain, from carotid distension rate and heart rate) and mBRS (carotid stiffness) were measured by high-precision carotid echo-tracking. PA was self-reported using the validated Baecke questionnaire. The associations between PA and nBRS and mBRS were quantified using multivariate linear regression analysis, separately in the working and nonworking population. In working adults (n=5039), occupational PA was associated with worse nBRS (unstandardized β=-0.02; [95% CI, -0.04 to -0.003]; P=0.022) whereas sport PA was associated with better nBRS (β=0.04; [95% CI, 0.02-0.07]; P=0.003) and mBRS (β=-0.05; [95% CI, -0.09 to -0.00001]; P=0.049). Neither leisure PA nor total PA was associated with nBRS or mBRS. In nonworking adults (n=3610), sport PA and total PA were associated with better mBRS (β=-0.08; [95% CI, -0.15 to 0.02]; P=0.012 and β=-0.05; [95% CI, -0.10 to 0.009]; P=0.018) but not nBRS. These findings suggest differential associations between domains of PA and BRS and may provide insights into the mechanisms underlying the association between occupational PA and cardiovascular disease.

TL;DR: This review summarizes the pharmacological studies performed in recent years on the ability of antihypertensive drugs to modify arterial compliance and describes the effects of these drugs on cardiac structure and function.
Abstract: The changes in arterial compliance following drug treatment have been studied mainly in hypertension. Physiologically, reduced arterial compliance independently affects blood pressure through an increase in systolic pressure and a decrease in diastolic pressure at any given value of mean arterial pressure. This review summarizes the pharmacological studies performed in recent years on the ability of antihypertensive drugs to modify arterial compliance. For the same decrease in mean arterial pressure, antihypertensive drugs may have differential effects improving arterial compliance (calcium channel blockers, converting enzyme inhibitors, alpha-blockers and some beta-blockers) or causing no change (dihydralazine, diuretics, propranolol) with resulting consequences on cardiac structure and function.

TL;DR: Meta-analysis has been necessary to clarify the net effect of a given polymorphism on arterial phenotype, and studies combining two or more gene polymorphisms were seldom performed.
Abstract: Association studies between candidate gene polymorphisms and arterial phenotype are numerous, and often provide conflicting results. Isolated studies have frequently proved inconclusive and meta-analysis have been necessary to clarify the net effect of a given polymorphism on arterial phenotype. Even in these cases, the contribution of a given gene polymorphism to the variance of a specific phenotype was limited. Although often mentioned, studies combining two or more gene polymorphisms were seldom performed.

TL;DR: These standards of care are intended to provide clinicians, patients, researchers, payors, and other interested individuals with the components of diabetes care, treatment goals, and tools to evaluate the quality of care.
Abstract: XI. STRATEGIES FOR IMPROVING DIABETES CARE D iabetes is a chronic illness that requires continuing medical care and patient self-management education to prevent acute complications and to reduce the risk of long-term complications. Diabetes care is complex and requires that many issues, beyond glycemic control, be addressed. A large body of evidence exists that supports a range of interventions to improve diabetes outcomes. These standards of care are intended to provide clinicians, patients, researchers, payors, and other interested individuals with the components of diabetes care, treatment goals, and tools to evaluate the quality of care. While individual preferences, comorbidities, and other patient factors may require modification of goals, targets that are desirable for most patients with diabetes are provided. These standards are not intended to preclude more extensive evaluation and management of the patient by other specialists as needed. For more detailed information, refer to Bode (Ed.): Medical Management of Type 1 Diabetes (1), Burant (Ed): Medical Management of Type 2 Diabetes (2), and Klingensmith (Ed): Intensive Diabetes Management (3). The recommendations included are diagnostic and therapeutic actions that are known or believed to favorably affect health outcomes of patients with diabetes. A grading system (Table 1), developed by the American Diabetes Association (ADA) and modeled after existing methods, was utilized to clarify and codify the evidence that forms the basis for the recommendations. The level of evidence that supports each recommendation is listed after each recommendation using the letters A, B, C, or E.
