Article Synopsis
  • ANGPTL3/4/8 proteins regulate lipoprotein lipase (LPL) activity, with ANGPTL8 forming complexes that influence ANGPTL4's function; however, their association with cardiovascular outcomes is under-researched.
  • This study involved measuring various ANGPTL proteins and complexes in two large population studies (LURIC and getABI) focusing on cardiovascular health and outcomes over several years.
  • Findings showed that while ANGPTL3/8 inhibited LPL activity and correlated with increased LDL-C and triglycerides, they did not predict cardiovascular death; however, ANGPTL4/8 and CD-ANGPTL4 were linked to higher diabetes prevalence and increased cardiovascular mortality risk.

Lower extremity amputation and requirement of peripheral artery revascularization are common outcomes of undiagnosed peripheral artery disease patients. In the current work, prediction models for the need of amputation or peripheral revascularization focused on hypertensive patients within seven years follow up are employed. We applied machine learning (ML) models using classifiers such as Extreme Gradient Boost (XGBoost), Random Forest (RF) and Adaptive Boost (AdaBoost), that will allow clinicians to identify the patients at risk of these two endpoints using simple clinical data.

Background: Diseases affecting the cardiovascular system are the most common cause of death worldwide. In addition to classical risk factors of atherosclerosis, long-term exposure to particulate matter with particles of size up to 10 µm (PM10) in the atmosphere has become an increasing focus of scientific attention in recent decades. This study analyses the associations of residential-associated air pollutants exposure with all-cause mortality and cardiovascular morbidity of older patients in a primary care setting.

Objective: In active early rheumatoid arthritis (RA), glucocorticoids are often used for bridging, due to the delayed action of methotrexate. This study was undertaken to compare the effect of 3 bridging strategies, including high-dose and low-dose prednisolone, on radiographic and clinical outcomes.

Methods: Adult RA patients from 1 rheumatology hospital and 23 rheumatology practices who presented with moderate/high disease activity were randomized (1:1:1) to receive 60 mg prednisolone (high-dose prednisolone [HDP]) or 10 mg prednisolone (low-dose prednisolone [LDP]) daily (tapered to 0 mg within 12 weeks) or placebo.

Background: In some areas of Germany, there is a shortage of specialist physicians for patients with inflammatory rheumatic diseases. Delegating certain medical care services to qualified, specialized rheumatological assistants (SRAs) might be an effective way to supplement the available capacity for specialized medical care.

Methods: Patients under stable treatment for rheumatoid arthritis (RA) or psoriatic arthritis (PsA) were included in this trial, which was designed to demonstrate, in a first step, the non-inferiority of a form of care involving delegation of physicians' tasks to SRAs (team-based care), in comparison to standard care, with respect to changes in disease activity at one year.

Background: Medications with an unfavorable risk-benefit profile in the elderly, and for which there are safer alternatives, are designated as potentially inappropriate medications (PIM). The RIME trial (Reduction of Potentially Inappropriate Medication in the Elderly) was based on PRISCUS, a list of PIM that was developed in 2010 for the German pharmaceuticals market. In this trial, it was studied whether special training and the PRISCUS card could lessen PIM and undesired drug-drug interactions (DDI) among elderly patients in primary care.

Objective: To explore factors that potentially impact external validation performance while developing and validating a prognostic model for hospital admissions (HAs) in complex older general practice patients.

Study Design And Setting: Using individual participant data from four cluster-randomised trials conducted in the Netherlands and Germany, we used logistic regression to develop a prognostic model to predict all-cause HAs within a 6-month follow-up period. A stratified intercept was used to account for heterogeneity in baseline risk between the studies.

Purpose: The common definition of asymptomatic peripheral artery disease (PAD) by a single determination of the ankle brachial index (ABI) has some uncertainty due to measurement errors. This may impact estimates of PAD incidence and assessment of PAD risk factors. To investigate this issue, we used three methods to define asymptomatic PAD and made use of data from the German Epidemiological Trial on Ankle Brachial Index (getABI).

Background: Beside their role in the diagnosis of heart failure in symptomatic patients with dyspnea, natriuretic peptides have been suggested to improve risk prediction of cardiac events and mortality in asymptomatic cohorts. We aimed to evaluate the prognostic value of NT-proBNP for cardiovascular and all-cause mortality above traditional risk factors in a prospective cohort study of unselected elderly patients in a representative primary care setting.

Methods: We followed 6382 patients of the getABI-study for 7 years.

Purpose: This study examined osteoporotic fractures and mortality in patients pretreated with bisphosphonates (BPs) during BP holidays and ongoing BP use.

Methods: Interview-based prospective observational study in a cohort of 1973 patients with BP treatment for at least 80% of the total time of the preceding 4 years. Patients were recruited from 146 primarily endocrinological, orthopedic and rheumatological practices and clinics across Germany between May 2013 and June 2015.

Background: In Germany, the care of patients with inflammatory arthritis could be improved. Although specialized rheumatology nurses could take over substantial aspects of patient care, this hardly occurs in Germany. Thus, the aim of the study is to examine structured nursing consultation in rheumatology practices.

Background: Persons of lower socio-economic status are at higher risk of disease, especially with respect to severe and chronic illnesses. To date, there have not been any studies with large case numbers regarding acute medical emergencies in this population.

Methods: In a retrospective study, data were obtained on all cases treated by emergency physicians in Bochum, Germany, in 2014/2015, including the diagnoses that were made by the emergency physicians.

Background: Aside from the fully licensed herbal medicines there are products on the European pharmaceutical market which are registered by virtue of their longstanding traditional use. The normal registration procedure does not apply to them because presently they do not meet the legal requirements for a full license as set out in the relevant European Union Directive. One of these requirements, "proof of tradition", has so far been dealt with in different ways and fails to meet the criteria of good practice.

Background: Multimorbidity is increasing in aging populations with a corresponding increase in polypharmacy as well as inappropriate prescribing. Depending on definitions, 25-50 % of patients aged 75 years or older are exposed to at least five drugs. Evidence is increasing that polypharmacy, even when guidelines advise the prescribing of each drug individually, can potentially cause more harm than benefit to older patients, due to factors such as drug-drug and drug-disease interactions.

Background: Although glucocorticoids are widely used in the treatment of patients with early rheumatoid arthritis, the best dosage of glucocorticoids with regards to efficacy and safety is not known.The aim of the study 'Comparison of the efficacy and safety of two starting dosages of prednisolone in early active rheumatoid arthritis' (CORRA) is to compare two standard glucocorticoid starting dosages and the non-use of glucocorticoids in the treatment of patients with early active rheumatoid arthritis on the background of the established 'anchor' therapy with methotrexate.

Methods/design: CORRA is an investigator-initiated, randomized, multicenter, double-blind, placebo-controlled trial with two treatment arms, starting with 60 mg or 10 mg prednisolone per day, tapered down to 5 mg prednisolone within eight weeks, and one placebo arm, each arm comprising 150 patients.

Objective: Intussusception (IS) is one of the most common paediatric emergencies, and the best mode of conservative reduction and its exact incidence remains unclear. For different reasons, availability of reliable incidence data are useful and additionally may be fundamental to monitor potential effects of recently introduced rotavirus (RV) vaccines.

Methods: We performed a prospective German nationwide surveillance between January 1, 2006 and December 31, 2007, followed by separate collection of all IS cases in a random sample of 31 clinics for an unbiased estimation of underreporting.

Objective: We aimed to investigate whether the post-exercise ankle brachial index (ABI) performed by primary care physicians offers useful information for the prediction of death or cardiovascular events, beyond the traditional resting ABI. An additional focus was on patients with intermittent claudication and normal resting ABI.

Methods: Using data from the 5-year follow-up of 6468 elderly patients in the primary care setting in Germany (getABI study) we used multivariate Cox regression models adjusted for age, gender and conventional risk factors to determine the association of resting ABI and/or post-exercise ABI and all-cause mortality/morbidity.

Background: Increased mortality in patients with anemia has been demonstrated in disabled, seriously ill or hospitalized patients. In industrialized nations with their aging societies, however, elderly but apparently healthy family-physician patients are an important demographic group from a public-health perspective. We therefore set out to evaluate the prevalence of anemia in this group and associations between anemia and 5-year all-cause mortality, adjusted for multiple other established risk factors and chronic diseases.

Background: Whether reducing time-to-surgery for elderly patients suffering from hip fracture results in better outcomes remains subject to controversial debates.

Methods: As part of a prospective observational study conducted between January 2002 and September 2003 on hip-fracture patients from 268 acute-care hospitals all over Germany, we investigated the relationship of time-to-surgery with frequency of post-operative complications and one-year mortality in elderly patients (age > or =65) with isolated proximal femoral fracture (femoral neck fracture or pertrochanteric femoral fracture). Patients with short (< or =12 h), medium (> 12 h to < or =36 h) and long (> 36 h) times-to-surgery, counting from the time of the fracture event, were compared for patient characteristics, operative procedures, post-operative complications and one-year mortality.

Background: The most commonly used survey methods are self-administered questionnaires, telephone interviews, and a mixture of both. But until now evidence out of randomised controlled trials as to whether patient responses differ depending on the survey mode is lacking. Therefore this study assessed whether patient responses to surveys depend on the mode of survey administration.
