Inflammatory Bowel Disease as a Precondition for Stroke or TIA: A Matter of Crohn's Disease Rather than Ulcerative Colitis.

2020

Abstract Background As a chronic systemic inflammation may be associated with an increased risk of vascular events, the aim of the present study was to assess the incidence of stroke and transient ischemic attack (TIA) in patients with inflammatory bowel disease over a period of 15 years. Methods This cohort study included patients for whom the initial diagnosis of an inflammatory bowel disease (IBD) (Crohn's disease: CD and ulcerative colitis: UC) was documented anonymously between 2000 and 2015 in 1,262 general practices in Germany. IBD patients were matched to patients without IBD using propensity scores based on age, sex, physician, co-diagnoses and co-therapies. Cox regression models w…

Association between sarcopenia and quality of life among adults aged ≥ 65 years from low- and middle-income countries

2022

Background Sarcopenia has been associated with a lower quality of life (QoL). However, studies on this association from low- and middle-income countries (LMICs) are scarce. Aims To examine the association between sarcopenia and QoL, in a large nationally representative sample of older adults from six LMICs. Methods Cross-sectional, community-based data from the WHO study on global ageing and adult health (SAGE) were analysed. Non-severe sarcopenia was defined as having low skeletal muscle mass (SMM) and weak handgrip strength but no slow gait speed, while severe sarcopenia was defined as having low SMM, weak handgrip strength, and slow gait speed. QoL was assessed with the 8-item WHO QoL in…

Multimorbidity and anxiety symptoms among adults aged 50 years and over from six low- and middle-income countries

2021

Currently, there are limited data on the association between multimorbidity (i.e., ≥ 2 chronic conditions) and anxiety, especially among the older population in low- and middle-income countries (LMICs). Thus, the aim of the present study was to examine the association between multimorbidity and anxiety symptoms in a large sample of adults aged ≥ 50 years from six LMICs (China, India, Ghana, Mexico, Russia, South Africa). Cross-sectional, nationally representative, community-based data from the Study on Global Ageing and Adult Health (SAGE) were analysed. A total of 11 chronic physical conditions were assessed. Anxiety symptoms referred to extreme/severe problems with worry or anxiety in the…

Non-alcoholic fatty liver disease increases the risk of incident chronic kidney disease

2020

BACKGROUND AND AIM: Non-alcoholic fatty liver disease (NAFLD) is a highly prevalent chronic liver disease. Its role in the development of extrahepatic co-morbidities is under investigation. The impact of NAFLD on the development of chronic kidney disease (CKD) is incompletely understood. The aim of this study was to explore the potential contribution of NAFLD on CKD in Germany. METHODS: The Disease Analyzer Database covering 7.49 million cases in Germany was explored for patients diagnosed with NAFLD between 2000 and 2015 and was matched 1:1 to a cohort without NAFLD. Matching criteria included age, sex, physician, index year and co-diagnoses associated with CKD. The primary outcomes of thi…

Prescription rates of common medications in patients with decompensated cirrhosis in Germany

2021

Adequate pharmacological treatment is of pivotal importance to improve prognosis in patients with decompensated liver cirrhosis. We studied the adherence to recommended pharmacological treatments as secondary prevention in cirrhotic patients following a first decompensation in German primary care.Using the Disease Analyzer Database, the current study sample included patients with liver cirrhosis who had an initial diagnosis of a first decompensation event between 2015 and 2018 (index date) and a follow-up time of at least 6 months after the index date. Pharmacological treatments following the 6 months after the index date were studied.The study included 1538 patients with a first decompensa…

Impact of Non-Alcoholic Fatty Liver Disease on Metabolic Comorbidities in Type 2 Diabetes Mellitus.

2021

Abstract Objective Type 2 Diabetes (T2D) is a major risk factor for the development and progression of non-alcoholic fatty liver disease (NAFLD). The published prevelance in epidemiological studies in this high risk population exceeds 70%. The aim of this analysis was to investigate the impact of NAFLD on T2D patients in Germany. Methods Using the Disease Analyzer Database (IQVIA), T2D patients with NAFLD diagnosed in Germany were matched to a cohort without NAFLD controlling for age, sex, physician, index year and metabolic comorbidities and assessed for their risk of developing myocardial infarction, stroke, peripheral arterial disease (PAD) or chronic kidney disease, as well as the type …

Nonalcoholic Fatty Liver Disease Increases the Risk of Anxiety and Depression.

2020

Nonalcoholic fatty liver disease (NAFLD), depression, and anxiety disorders are frequent diseases, and data on mutual influence are inconsistent. The aim of this study was to explore the incidence of depression and anxiety in a large primary care cohort in Germany and to study the impact of NAFLD over a 10‐year time frame. Patients with NAFLD diagnosed between 2010 and 2015 were matched to a cohort without NAFLD controlling for age, sex, physician, index year, and Charlson comorbidity index. The primary outcome of the study was the incidence of depression, anxiety, and first prescription of antidepressant drugs. We compared 19,871 patients with NAFLD to 19,871 matched controls.

Association between cooking fuels and mild cognitive impairment among older adults from six low- and middle-income countries

2022

AbstractThere is a small body of evidence suggesting that unclean cooking fuel use may be associated with cognitive decline. However, to date, no study has investigated the association between unclean cooking fuel and mild cognitive impairment (MCI). Thus, we investigated the association between cooking fuel type or ventilation type and MCI among adults aged ≥ 65 years using nationally representative datasets from six low- and middle-income countries. Cross-sectional, community-based data from the World Health Organization (WHO) Study on global Ageing and adult health (SAGE) were analyzed. MCI was defined using the National Institute on Aging-Alzheimer's Association criteria. Unclean cookin…

Proton pump inhibitors increase risk of bone fractures in men with cirrhosis: a population-based study

2020

Bone fractures are a frequent complication in patients with cirrhosis. Proton pump inhibitors (PPIs) are among the most frequently prescribed medications and may impair bone quality and quantity.To investigate whether PPI use predisposes patients with cirrhosis to bone fractures.We performed a population-based case-control study exploring a sample of patients with cirrhosis derived from the Disease Analyzer database. In total, 1795 cirrhotic patients with fractures were compared to 10 235 cirrhotic patients without fractures. PPI use overall and the cumulative PPI dose 5 years prior to the index date were analysed. To estimate the association between PPI use and fractures, logistic regressi…

The association of physical multimorbidity with suicidal ideation and suicide attempts in England: A mediation analysis of influential factors

2022

Background: Suicide is one of the most important causes of deaths in the United Kingdom, and the numbers are currently increasing. Aim: There are numerous identified determinants of suicidality, and physical multimorbidity is potentially important but is currently understudied. Thus, this study aims to investigate the association of physical multimorbidity with suicidality. Methods: Cross-sectional data from the Adult Psychiatric Morbidity Survey 2007, which was conducted in England between October 2006 and December 2007 by the National Center for Social Research and Leicester University were analyzed. Respondents were asked about 20 physical health conditions, and suicidal ideation and sui…
