Postrenal anuria in pelvic or acetabular injury: a report of three cases.
1996
Renal failure due to obstruction by a retroperitoneal hematoma is a rarely discussed complication in pelvic or acetabular fractures. Three cases of this obstructive uropathy are presented. They were successfully treated with removal of the hematoma and draining of the retroperitoneal space.
Effect of Lowering LDL Cholesterol Substantially Below Currently Recommended Levels in Patients With Coronary Heart Disease and Diabetes
2006
OBJECTIVE—The Treating to New Targets study showed that intensive lipid-lowering therapy with atorvastatin 80 mg/day provides significant clinical benefit beyond that afforded by atorvastatin 10 mg/day in patients with stable coronary heart disease (CHD). The objective of our study was to investigate whether similar benefits of high-dose intensive atorvastatin therapy can be achieved in patients with CHD and diabetes. RESEARCH DESIGN AND METHODS—A total of 1,501 patients with diabetes and CHD, with LDL cholesterol levels of <130 mg/dl, were randomized to double-blind therapy with either atorvastatin 10 (n = 753) or 80 (n = 748) mg/day. Patients were followed for a median of 4.9 years…
Abstract WP201: Stroke Patients With Atrial Fibrillation Detected by 72 hour- versus Prolonged ECG-monitoring
2018
Background: Detecting concealed paroxysmal atrial fibrillation (pAF) is a major focus in the workup of ischemic-stroke-patients. The minimal ECG-monitoring for stroke patients was recently expanded from 24 to 72 hours. However, it has been shown that even more prolonged monitoring reveals further pAF-cases. Our aim was to determine, whether known predictors for underlying pAF differ between stroke patients with AF that occurs on shorter (72h) or more prolonged ECG-monitoring (>72h). Methods: The Find-AF RANDOMISED -trial (NCT01855035) evaluated 3x10-day Holter-ECG vs. standard-care in patients > 60 years with acute ischemic strokes with the primary endpoint of novel pAF after 6 month…
Abstract 124: How to Preselect Stroke Patients for Enhanced ECG-Monitoring - Evaluation of Predictors of Paroxysmal Atrial Fibrillation in "Find-AFra…
2019
Background: Detecting concealed paroxysmal atrial fibrillation (pAF) is a major focus of the workup of ischemic-stroke-patients, but requires elaborate ECG-monitoring. We aimed to evaluate pre-specified predictors to determine stroke patients with an increased probability of underlying pAF. We applied cut-off-levels recently suggested by the German Stroke Society 1 . Methods: The Find-AF RANDOMISED -trial (NCT01855035) evaluated 3x10-day Holter-ECG vs. standard-care in 398 patients > 60 years with acute ischemic strokes. The primary endpoint was novel pAF after 6 months. 27 patients in the intervention arm (13.5 %) and 9 patients in the control arm (9.0 %) met the primary endpoint (p=0.…
Biology of Longevity: Role of the Innate Immune System
2006
Genetic factors play a relevant role in the attainment of longevity because they are involved in cell maintenance systems, including the immune system. In fact, longevity may be correlated with optimal functioning of clonotypic and natural immunity. The aging of the immune system, known as immunosenescence, is the consequence of the continuous attrition caused by chronic antigenic overload. The antigenic load results in the progressive generation of inflammatory responses involved in age-related diseases. Most of the parameters influencing immunosenescence appear to be under genetic control, and immunosenescence fits with the basic assumptions of evolutionary theories of aging, such as anta…
Mediterranean Diet and Cardiovascular Health: Teachings of the PREDIMED Study123
2014
The PREDIMED (Prevención con Dieta Mediterránea) study was designed to assess the long-term effects of the Mediterranean diet (MeDiet) without any energy restriction on incident cardiovascular disease (CVD) as a multicenter, randomized, primary prevention trial in individuals at high risk. Participants were randomly assigned to 3 diet groups: 1) MeDiet supplemented with extra-virgin olive oil (EVOO); 2) MeDiet supplemented with nuts; and 3) control diet (advice on a low-fat diet). After 4.8 y, 288 major CVD events occurred in 7447 participants; crude hazard ratios were 0.70 (95% CI: 0.53, 0.91) for the MeDiet + EVOO and 0.70 (95% CI: 0.53, 0.94) for the MeDiet + nuts compared with the contr…
Thresholds of handgrip strength for all-cause, cancer, and cardiovascular mortality: A systematic review with dose-response meta-analysis.
2022
Background While handgrip strength is associated with all-cause and cause-specific mortality, whether such associations are dose-dependent is largely unknown. Therefore, we conducted a systematic review on the dose-response relationship of handgrip strength with all-cause mortality, cancer, and cardiovascular mortality. Methods The data source included three electronic databases (PubMed/MEDLINE, Web of Science and Scopus) from inception to 8 February 2022. Prospective cohort studies of healthy adults with objective measures of handgrip strength were included. Two researchers independently screened studies, extracted data, and assessed risk of bias. We used estimates regarding handgrip stren…
Electrocardiographic Diagnosis of Atrial Tachycardia: Classification, P-Wave Morphology, and Differential Diagnosis with Other Supraventricular Tachy…
2015
Atrial tachycardia is defined as a regular atrial activation from atrial areas with centrifugal spread, caused by enhanced automaticity, triggered activity or microreentry. New ECG classification differentiates between focal and macroreentrant atrial tachycardia. Macroreentrant atrial tachycardias include typical atrial flutter and other well characterized macroreentrant circuits in right and left atrium. Typical atrial flutter has been described as counterclockwise reentry within right atrial and it presents a characteristic ECG “sawtooth” pattern on the inferior leads. The foci responsible for focal atrial tachycardia do not occur randomly throughout the atria but tend to cluster at chara…
Aging Negatively Affects Estrogens-Mediated Effects on Nitric Oxide Bioavailability by Shifting ERα/ERβ Balance in Female Mice
2011
AIMS: Aging is among the major causes for the lack of cardiovascular protection by estrogen (E2) during postmenopause. Our study aims to determine the mechanisms whereby aging changes E2 effects on nitric oxide (NO) production in a mouse model of accelerated senescence (SAM). METHODS AND RESULTS: Although we found no differences on NO production in females SAM prone (SAMP, aged) compared to SAM resistant (SAMR, young), by either DAF-2 fluorescence or plasmatic nitrite/nitrate (NO2/NO3), in both cases, E2 treatment increased NO production in SAMR but had no effect in SAMP. Those results are in agreement with changes of eNOS protein and gene expression. E2 up-regulated eNOS expression in SAMR…
CCR5 Receptor: Biologic and Genetic Implications in Age-Related Diseases
2007
The CC chemokine receptor 5 (CCR5) is a member of CC-chemokine receptor family. CCR5 has the characteristic structure of a seven transmembrane G protein-coupled receptor (GPCR), which regulates trafficking and effector functions of memory/effector Th1 cells, macrophages, NK cells, and immature dendritic cells. CCR5 and its ligands are important molecules in viral pathogenesis. CCR5 represents the co-receptor for macrophage (M) and dual (T cell and M)-tropic immunodeficiency viruses. Recent evidence has also demonstrated the role of CCR5 in a variety of human diseases, ranging from infectious and inflammatory diseases to cancer. In this article, we describe the involvement of CCR5 in two age…
