Left ventricular mass increase is associated with cognitive decline and dementia in the elderly independently of blood pressure

Aims Left ventricular (LV) mass increase is considered part of composite target organ damage in hypertension and an independent risk factor for cardiovascular (CV) events. This study was designed to explore whether left ventricular mass index (LVMI) is associated with cognitive decline and dementia in elderly subjects, independently of blood pressure (BP) levels. Methods and results Four hundred subjects (mean age 79 ± 6 years) were studied. Left ventricular mass was measured echocardiographically in accordance with American Society of Echocardiography and normalized for body height to the 2.7 (LVMI). Global cognitive function was evaluated with the mini-mental state examination (MMSE) (maximum score 30). Dementia was defined as an MMSE score <21. Arterial stiffness was evaluated as carotid–femoral pulse wave velocity by Complior®. Prevalence of hypertension was 70% and diabetes mellitus was diagnosed in 25%. No significant differences in traditional CV risk factors were observed across LVMI quartiles. Mini-mental state examination showed an inverse trend across LVMI quartiles (the higher the LVMI, the lower the MMSE, P for trend <0.05); systolic and diastolic BP levels were not different across LVMI quartiles. In multivariable logistic regression models, including age, sex, BP levels, and use of antihypertensive drugs as covariates, the highest LVMI was found to be independently associated with a two-fold higher likelihood of having dementia. The association persisted significant even after adjustment for arterial stiffness. Conclusion In elderly subjects, LVMI is associated with a progressive cognitive decline. This association is independent of BP levels and/or large artery stiffness

JAK-Inhibitors for the Treatment of Rheumatoid Arthritis : A Focus on the Present and an Outlook on the Future

Janus kinase inhibitors (JAKi) belong to a new class of oral targeted disease-modifying drugs which have recently revolutionized the therapeutic panorama of rheumatoid arthritis (RA) and other immune-mediated diseases, placing alongside or even replacing conventional and biological drugs. JAKi are characterized by a novel mechanism of action, consisting of the intracellular interruption of the JAK-STAT pathway crucially involved in the immune response. The aim of this narrative review is to globally report the most relevant pharmacological features and clinical outcomes of the developed and incoming JAKi for RA, based on the available preclinical and clinical evidence. A total of 219 papers, including narrative and systematic reviews, randomized controlled trials (RCTs), observational studies, case reports, guidelines, and drug factsheets, were selected. The efficacy and safety profile of both the first generation JAKi (baricitinib and tofacitinib) and the second generation JAKi (upadacitinib, filgotinib, peficitinib, decernotinib and itacitinib) were compared and discussed. Results from RCTs and real-life data are encouraging and outline a rapid onset of the pharmacologic effects, which are maintained during the time. Their efficacy and safety profile are comparable or superior to those of biologic agents and JAKi proved to be efficacious when given as monotherapy. Finally, the manufacturing of JAKi is relatively easier and cheaper than that of biologics, thus increasing the number of compounds being formulated and tested for clinical use

A model to estimate the lifetime health outcomes of patients with Type 2 diabetes: the United Kingdom Prospective Diabetes Study (UKPDS) Outcomes Model (UKPDS no. 68)

&lt;i&gt;Aims/hypothesis&lt;/i&gt; The aim of this study was to develop a simulation model for Type 2 diabetes that can be used to estimate the likely occurrence of major diabetes-related complications over a lifetime, in order to calculate health economic outcomes such as quality-adjusted life expectancy. &lt;i&gt;Methods&lt;/i&gt; Equations for forecasting the occurrence of seven diabetes-related complications and death were estimated using data on 3642 patients from the United Kingdom Prospective Diabetes Study (UKPDS). After examining the internal validity, the UKPDS Outcomes Model was used to simulate the mean difference in expected quality-adjusted life years between the UKPDS regimens of intensive and conventional blood glucose control. &lt;i&gt;Results&lt;/i&gt; The models forecasts fell within the 95% confidence interval for the occurrence of observed events during the UKPDS follow-up period. When the model was used to simulate event history over patients lifetimes, those treated with a regimen of conventional glucose control could expect 16.35 undiscounted quality-adjusted life years, and those receiving treatment with intensive glucose control could expect 16.62 quality-adjusted life years, a difference of 0.27 (95% CI: –0.48 to 1.03). &lt;i&gt;Conclusions/interpretations&lt;/i&gt; The UKPDS Outcomes Model is able to simulate event histories that closely match observed outcomes in the UKPDS and that can be extrapolated over patients lifetimes. Its validity in estimating outcomes in other groups of patients, however, remains to be evaluated. The model allows simulation of a range of long-term outcomes, which should assist in informing future economic evaluations of interventions in Type 2 diabetes

Effect of Student Involvement on Patient Perceptions of Ambulatory Care Visits

OBJECTIVE: To determine if patient satisfaction with ambulatory care visits differs when medical students participate in the visit. DESIGN: Randomized controlled trial. SETTING: Academic general internal medicine practice. PARTICIPANTS: Outpatients randomly assigned to see an attending physician only (N = 66) or an attending physician plus medical student (N = 68). MEASUREMENTS AND MAIN RESULTS: Patient perceptions of the office visit were determined by telephone survey. Overall office visit satisfaction was higher for the “attending physician only” group (61% vs 48% excellent), although this was not statistically significant (P = .16). There was no difference between the study groups for patient ratings of their physician overall (80% vs 85% excellent; P = .44). In subsidiary analyses, patients who rated their attending physician as “excellent” rated the overall office visit significantly higher in the “attending physician only” group (74% vs 55%; P = .04). Among patients in the “attending physician plus medical student” group, 40% indicated that medical student involvement “probably” or “definitely” did not improve their care, and 30% responded that they “probably” or “definitely” did not want to see a student at subsequent office visits. CONCLUSIONS: Although our sample size was small, we found no significant decrement in patient ratings of office visit satisfaction from medical student involvement in a global satisfaction survey. However, a significant number of patients expressed discontent with student involvement in the visit when asked directly. Global assessment of patient satisfaction may lack sensitivity for detection of dissatisfaction. Future research in this area should employ more sensitive measures of patient satisfaction

Targeted Next-Generation Sequencing Indicates a Frequent Oligogenic Involvement in Primary Ovarian Insufficiency Onset

Primary ovarian insufficiency (POI) is one of the major causes of female infertility associated with the premature loss of ovarian function in about 3.7% of women before the age of 40. This disorder is highly heterogeneous and can manifest with a wide range of clinical phenotypes, ranging from ovarian dysgenesis and primary amenorrhea to post-pubertal secondary amenorrhea, with elevated serum gonadotropins and hypoestrogenism. The ovarian defect still remains idiopathic in some cases; however, a strong genetic component has been demonstrated by the next-generation sequencing (NGS) approach of familiar and sporadic POI cases. As recent evidence suggested an oligogenic architecture for POI, we developed a target NGS panel with 295 genes including known candidates and novel genetic determinants potentially involved in POI pathogenesis. Sixty-four patients with early onset POI (range: 10–25 years) of our cohort have been screened with 90% of target coverage at 50×. Here, we report 48 analyzed patients with at least one genetic variant (75%) in the selected candidate genes. In particular, we found the following: 11/64 patients (17%) with two variants, 9/64 (14%) with three variants, 9/64 (14%) with four variants, 3/64 (5%) with five variants, and 2/64 (3%) with six variants. The most severe phenotypes were associated with either the major number of variations or a worse prediction in pathogenicity of variants. Bioinformatic gene ontology analysis identified the following major pathways likely affected by gene variants: 1) cell cycle, meiosis, and DNA repair; 2) extracellular matrix remodeling; 3) reproduction; 4) cell metabolism; 5) cell proliferation; 6) calcium homeostasis; 7) NOTCH signaling; 8) signal transduction; 9) WNT signaling; 10) cell death; and 11) ubiquitin modifications. Consistently, the identified pathways have been described in other studies dissecting the mechanisms of folliculogenesis in animal models of altered fertility. In conclusion, our results contribute to define POI as an oligogenic disease and suggest novel candidates to be investigated in patients with POI

Genetic variation of Glucose Transporter-1 (GLUT1) and albuminuria in 10,278 European Americans and African Americans: a case-control study in the Atherosclerosis Risk in Communities (ARIC) Study

<p>Abstract</p> <p>Background</p> <p>Evidence suggests glucose transporter-1(<it>GLUT1</it>) genetic variation affects diabetic nephropathy and albuminuria. Our aim was to evaluate associations with albuminuria of six <it>GLUT1 </it>single nucleotide polymorphisms(SNPs), particularly <it>XbaI </it>and the previously associated <it>Enhancer-2(Enh2</it>) SNP.</p> <p>Methods</p> <p>A two-stage case-control study was nested in a prospective cohort study of 2156 African Americans and 8122 European Americans with urinary albumin-to-creatinine ratio(ACR). Cases comprised albuminuria(N = 825; ≥ 30 μg/mg) and macroalbuminuria(N = 173; ≥ 300 μg/mg). ACR < 30 μg/mg classified controls(n = 9453). Logistic regression and odds ratios(OR) assessed associations. The evaluation phase(stage 1, n = 2938) tested associations of albuminuria(n = 305) with six <it>GLUT1 </it>SNPs: rs841839, rs3768043, rs2297977, <it>Enh2</it>(rs841847) <it>Xba</it>I(rs841853), and rs841858. <it>Enh2 </it>was examined separately in the replication phase(stage 2, n = 7340) and the total combined sample (n = 10,278), with all analyses stratified by race and type 2 diabetes.</p> <p>Results</p> <p>In European Americans, after adjusting for diabetes and other <it>GLUT1 </it>SNPs in stage 1, <it>Enh2 </it>risk genotype(TT) was more common in albuminuric cases(OR = 3.37, P = 0.090) whereas <it>XbaI </it>(OR = 0.94, p = 0.931) and remaining SNPs were not. In stage 1, the <it>Enh2 </it>association with albuminuria was significant among diabetic European Americans(OR = 2.36, P = 0.025). In African Americans, <it>Enh2 </it>homozygosity was rare(0.3%); <it>XbaI </it>was common(18.0% AA) and not associated with albuminuria. In stage 2(n = 7,340), <it>Enh2 </it>risk genotype had increased but non-significant OR among diabetic European Americans(OR = 1.66, P = 0.192) and not non-diabetics(OR = 0.99, p = 0.953), not replicating stage 1. Combining stages 1 and 2, <it>Enh2 </it>was associated with albuminuria(OR 2.14 [1.20-3.80], P = 0.009) and macroalbuminuria(OR 2.69, [1.02-7.09], P = 0.045) in diabetic European Americans. The <it>Enh2 </it>association with macroalbuminuria among non-diabetic European Americans with fasting insulin(OR = 1.84, P = 0.210) was stronger at the highest insulin quartile(OR = 4.08, P = 0.040).</p> <p>Conclusions</p> <p>As demonstrated with type 1 diabetic nephropathy, the <it>GLUT1 Enh2 </it>risk genotype, instead of <it>Xba</it>I, may be associated with type 2 diabetic albuminuria among European Americans, though an association is not conclusive. The association among diabetic European Americans found in stage 1 was not replicated in stage 2; however, this risk association was evident after combining all diabetic European Americans from both stages. Additionally, our results suggest this association may extend to non-diabetics with high insulin concentrations. Rarity of the <it>Enh2 </it>risk genotype among African Americans precludes any definitive conclusions, although data suggest a risk-enhancing role.</p
