Software-based analysis of 1-hour Holter ECG to select for prolonged ECG monitoring after stroke.
2020
Abstract Objective Identification of ischemic stroke patients at high risk for paroxysmal atrial fibrillation (pAF) during 72 hours Holter ECG might be useful to individualize the allocation of prolonged ECG monitoring times, currently not routinely applied in clinical practice. Methods In a prospective multicenter study, the first analysable hour of raw ECG data from prolonged 72 hours Holter ECG monitoring in 1031 patients with acute ischemic stroke/TIA presenting in sinus rhythm was classified by an automated software (AA) into “no risk of AF” or “risk of AF” and compared to clinical variables to predict AF during 72 hours Holter‐ECG. Results pAF was diagnosed in 54 patients (5.2%; mean …
Dietary protein restriction reduces circulating VLDL triglyceride levels via CREBH-APOA5-dependent and -independent mechanisms
2018
Hypertriglyceridemia is an independent risk factor for cardiovascular disease. Dietary interventions based on protein restriction (PR) reduce circulating triglycerides (TGs), but underlying mechanisms and clinical relevance remain unclear. Here, we show that 1 week of a protein-free diet without enforced calorie restriction significantly lowered circulating TGs in both lean and diet-induced obese mice. Mechanistically, the TG-lowering effect of PR was due, in part, to changes in very low-density lipoprotein (VLDL) metabolism both in liver and peripheral tissues. In the periphery, PR stimulated VLDL-TG consumption by increasing VLDL-bound APOA5 expression and promoting VLDL-TG hydrolysis and…
Cyclophosphamide plus vincristine and prednisone in the treatment of severe pemphigus vulgaris refractory to conventional therapy
1992
Five patients with severe pemphigus vulgaris refractory to conventional therapy with azathioprine and corticosteroids were treated with cyclophosphamide, vincristine and prednisone. One patient was not evaluable, while the remaining four patients showed a complete response. Duration of response was in the range of 13-94 months. Toxicity was mainly represented by alopecia, myelosuppression and gastrointestinal side-effects such as nausea/vomiting. Although cyclophosphamide and vincristine may induce severe side-effects, this association may be useful in controlling severe disease resistant to previous conventional therapies.
Effect of contact lens surface properties on comfort, tear stability and ocular physiology.
2018
Aim: Retrospective analysis of different contact lens wearing groups suggests lens surface lubricity is the main factor influencing contact lens comfort. However, the examined commercially available contact lenses differ in material and design as well as surface properties. Hence this study isolates the contribution of lens surface properties using an ultra-thin coating technology. Methods: Nineteen habitual contact lens wearers (21.6. ±. 1.7years) wore formofilcon B soft monthly disposable contact lenses with and without coating technology modified surface properties for a month each in a randomised double-masked cross-over study. Objective non-invasive: breakup time (NIKBUT), NIKBUT avera…
Domain-specific characterisation of early cognitive impairment following spontaneous intracerebral haemorrhage.
2018
Cognitive deficits after spontaneous intracerebral haemorrhage (ICH) are common and result in functional impairment, but few studies have examined deficits across cognitive domains in the subacute phase. This study aims to describe the cognitive profile following acute ICH and explore how cerebral amyloid angiopathy (CAA) may impact performance. We retrospectively reviewed 187 consecutive patients with ICH (mean age 58.9 years, 55.6% male) with available imaging and neuropsychological data (median 12 days after stroke). In our cohort, 84% (n = 158) were impaired in at least one cognitive domain and 65% (n = 122) in two or more domains. Deficits in non-verbal IQ (76.6%), information processi…
Sex hormones modulate pathogenic processes in experimental traumatic brain injury.
2018
Clinical and animal studies have revealed sex-specific differences in histopathological and neurological outcome after traumatic brain injury (TBI). The impact of perioperative administration of sex steroid inhibitors on TBI is still elusive. Here, we subjected male and female C57Bl/6N mice to the controlled cortical impact (CCI) model of TBI and applied pharmacological inhibitors of steroid hormone synthesis, that is, letrozole (LET, inhibiting estradiol synthesis by aromatase) and finasteride (FIN, inhibiting dihydrotestosterone synthesis by 5α-reductase), respectively, starting 72 h prior CCI, and continuing for a further 48 h after CCI. Initial gene expression analyses showed that andro…
Plasma metabolites predict both insulin resistance and incident type 2 diabetes: a metabolomics approach within the Prevención con Dieta Mediterránea…
2019
Background Insulin resistance is a complex metabolic disorder and is often associated with type 2 diabetes (T2D). Objectives The aim of this study was to test whether baseline metabolites can additionally improve the prediction of insulin resistance beyond classical risk factors. Furthermore, we examined whether a multimetabolite model predicting insulin resistance in nondiabetics can also predict incident T2D. Methods We used a case-cohort study nested within the Prevencion con Dieta Mediterranea (PREDIMED) trial in subsets of 700, 500, and 256 participants without T2D at baseline and 1 and 3 y. Fasting plasma metabolites were semiquantitatively profiled with liquid chromatography-tandem m…
Changes in CDKN2A/2B expression associate with T-cell phenotype modulation in atherosclerosis and type 2 diabetes mellitus.
2018
Previous studies indicate a role of CDKN2A/2B/2BAS genes in atherosclerosis and type 2 diabetes mellitus (T2DM). Progression of these diseases is accompanied by T-cell imbalance and chronic inflammation. Our main objective was to investigate a potential association between CDKN2A/2B/2BAS gene expression and T cell phenotype in T2DM and coronary artery disease (CAD) in humans, and to explore the therapeutic potential of these genes to restore immune cell homeostasis and disease progression. Reduced mRNA levels of CDKN2A (p16Ink4a), CDKN2B (p15Ink4b), and CDKN2BAS were observed in human T2DM and T2DM-CAD subjects compared with controls. Protein levels of p16Ink4a and p15Ink4b were also dimini…
Current views on intravesical treatment and chemoprophylaxis of superficial bladder cancer. The present role of epirubicin and doxorubicin.
1993
Since 1972, a large number of studies have shown that intravesical treatment with doxorubicin (adriamycin) is effective against carcinoma in situ and multiple papillary tumors. Furthermore, it significantly reduces the recurrence rate after transurethral resection. Its efficacy has been compared with that of Bacillus Calmette-Guerin (BCG), which is the only treatment accepted by the US Food and Drug Administration for therapy of carcinoma in situ (Tis). In more recent years, a few studies have been performed using intravesical epirubicin in the hope that different properties of the molecule might enhance the activity of the anthracyclines, but produce fewer and milder side-effects. After we…
Decrease in αβ/γδ T-cell ratio is accompanied by a reduction in high-fat diet-induced weight gain, insulin resistance, and inflammation.
2018
The implication of αβ and γδ T cells in obesity-associated inflammation and insulin resistance (IR) remains uncertain. Mice lacking γδ T cells show either no difference or a decrease in high-fat diet (HFD)-induced IR, whereas partial depletion in γδ T cells does not protect from HFD-induced IR. αβ T-cell deficiency leads to a decrease in white adipose tissue (WAT) inflammation and IR without weight change, but partial depletion of these cells has not been studied. We previously described a mouse model overexpressing peroxisome proliferator-activated receptor β (PPAR-β) specifically in T cells [transgenic (Tg) T-PPAR-β] that exhibits a partial depletion in αβ T cells and no change in γδ T-ce…
