Vitamin mortality

Benjamin A Steinberg
Atrial fibrillation (AF) is the most common cardiac arrhythmia, and conveys a significant risk of morbidity and mortality due to related stroke and systemic embolism. Oral anticoagulation (OAC) is the mainstay of thromboembolism prevention and management of anticoagulation can be challenging. For patients without significant valvular disease, decisions around anticoagulation therapy are first based on the presence of additional stroke risk factors, as measured by the CHA2DS2-VASc score. Patients with increased CHA2DS2-VASc scores (by regional guidelines) should next be evaluated to determine if they are candidates for non-vitamin K antagonist oral anticoagulant (NOAC) therapy...

Description: Calcium is the dominant mineral present in bone and a shortfall nutrient in the American diet. Supplements have been recommended for persons who do not consume adequate calcium from their diet as a standard strategy for the prevention of osteoporosis and related fractures. Whether calcium with or without vitamin D supplementation is beneficial or detrimental to vascular health is not known. Methods: The National Osteoporosis Foundation and American Society for Preventive Cardiology convened an expert panel to evaluate the effects of dietary and supplemental calcium on cardiovascular disease based on the existing peer-reviewed scientific literature...

Aside from its well-known effects on bone and mineral metabolism, vitamin D may also play an important role in extra-skeletal processes like immunologic diseases, cancer, or cardiovascular diseases. Even though meta-analyses showed that vitamin D supplementation reduces fractures, falls, and overall mortality, its potential benefits did not find universal acclaim. Several health care authorities published Recommended Dietary Allowances (RDAs) for vitamin D, most of them ranging from 600 to 800 international units (IU) per day, corresponding to a serum level of 25-hydroxyvitamin D of at least 20 ng/mL (50 nmol/L)...

Venous thromboembolism (VTE), which constitutes pulmonary embolism and deep vein thrombosis, is a common disorder associated with significant morbidity and mortality. Landmark trials have shown that direct oral anticoagulants (DOACs) are as effective as conventional anticoagulation with vitamin K antagonists (VKA) in prevention of VTE recurrence and associated with less bleeding. This has paved the way for the recently published guidelines to change their recommendations in favor of DOACs in acute and long-term treatment of VTE in patients without cancer...

Pulmonary embolism (PE) and venous thromboembolism (VTE) are common diagnoses in the emergency department (ED), with significant potential morbidity and mortality. As a result, historically nearly all patients with PE have been admitted to the hospital for observation and treatment. In recent years, the ability to rapidly and accurately risk stratify patients with VTE according to their risk of short-term clinical deterioration has supported outpatient treatment, and non-vitamin K antagonist oral anticoagulants (NOACs) have further facilitated this approach...

OBJECTIVE: Vitamin D deficiency has been associated with increased risk and adverse outcomes in many clinical settings including cardiovascular disease, stroke, and critically ill patients. Therefore we aimed to determine whether vitamin D deficiency had any effect in aneurysmal subarachnoid hemorrhage (aSAH) clinical outcomes. METHODS: A retrospective record review was conducted in a tertiary community hospital in Puerto Rico. Adult patients admitted to the neurosurgical intensive care unit (NICU) with a diagnosis of aSAH from January 2013 to July 2014, who had a 25-hydroxyvitamin-D level drawn, were included...

BACKGROUND: Recent improvements in atrial fibrillation diagnosis and management have prompted the initiation of various registries, predominantly to assess adherence to new guidelines, but also to address the pending questions of safety and effectiveness of newly introduced management options in 'real world' clinical practice settings. In this review we appraise antithrombotic treatment patterns for stroke prevention in atrial fibrillation registries. METHODS AND RESULTS: We searched PubMed, Science Direct and the Cochrane databases for registries focusing on stroke thromboprophylaxis in atrial fibrillation...

Parathyroid hormone (PTH) measurement in serum or plasma is a necessary tool for the exploration of calcium/phosphorus disorders, and is widely used as a surrogate marker to assess skeletal and mineral disorders associated with chronic kidney disease (CKD), referred to as CKD-bone mineral disorders (CKD-BMD). CKD currently affects >10% of the adult population in the United States and represents a major health issue worldwide. Disturbances in mineral metabolism and fractures in CKD patients are associated with increased morbidity and mortality...

Microbes are mostly important for the digestion of food, the absorption of some micronutrients, and the production of vitamins. The microbiota stimulates lymphoid structures in the gastrointestinal mucosa and decrease pathogens by competing for nutrients and space. Bacterial translocation is defined as the escape of gut bacteria and their products through the intestinal mucosa to the outside of the intestine as portovenous or systemic circulation. This is induced by a leaky gut barrier. There is evidence for a role of intestinal permeability in the pathogenesis of nonalcoholic fatty liver disease...

PURPOSE OF REVIEW: Hemorrhagic stroke comprises approximately 15% to 20% of all strokes. This article provides readers with an understanding of the indications and significance of various neuroimaging techniques available for patients presenting with hemorrhagic strokes of distinct causes. RECENT FINDINGS: The most common initial neuroimaging study is a noncontrast head CT, which allows for the identification of hemorrhage. Once an intracranial hemorrhage has been identified, the pattern of blood and the patient's medical history, neurologic examination, and laboratory studies lead the practitioner to pursue further neuroimaging studies to guide the medical, surgical, and interventional management...

Vitamin A-derived retinoic acid (RA) signals are critical for the development of several organs, including the pancreas. However, the tissue-specific control of RA synthesis in organ and cell lineage development has only poorly been addressed in vivo. Here we show that Retinol dehydrogenase-10 (Rdh10), a key enzyme in embryonic RA production, has important functions in pancreas organogenesis and endocrine cell differentiation. Rdh10 was expressed in the developing pancreas epithelium and surrounding mesenchyme...

AIM: Evaluation of secondary hyperparathyroidism (SHPT) and its prognostic impact on all-cause mortality in elderly males with heart failure (HF). METHODS: Seventy three males (67 ± 7 years old) with systolic HF were included. Baseline PTH was measured. Patients were grouped according to PTH cut-off levels of 65 pg/ml (>65 pg/ml = SHPT vs. normal PTH). All-cause mortality was evaluated at 6-year follow-up. RESULTS: SHPT was diagnosed in 43 (59 %) patients...

BACKGROUND: Early infancy is a high-risk period for severe acute respiratory infection (ARI), particularly in low-income countries with resource-limited health systems. Lower respiratory tract infection (LRTI) is commonly preceded by upper respiratory infection (URTI), and often caused by respiratory syncytial virus (RSV), influenza and other common community-acquired viral pathogens. Vitamin D status is a candidate modifiable early-life determinant of the host antiviral immune response and thus may influence the risk of ARI-associated morbidity in high-risk populations...

Introduction: Bone metabolism disorder (BMD) and vascular dysfunction contribute to excess cardiovascular mortality observed in hemodialysis patients. Vascular dysfunction, a new marker of atherosclerosis, can play a role in this risk. Even though associated with higher mortality in the general population, such vascular evaluation in patients on hemodialysis has not been extensively studied. Methods: In this cross-sectional study, hemodialysis patients were submitted to flow-mediated dilation, subendocardial viability ratio (SEVR) and ejection duration index assessment, in order to estimate the impact of BMD markers on vascular dysfunction...

BACKGROUND: In sub-Saharan Africa, one-third of all births are small for gestational age (SGA), and 4.4 million children are stunted; both conditions increase the risk of child mortality. SGA has also been shown to increase the risk of stunting. OBJECTIVE: We tested whether the association between SGA and postneonatal mortality is mediated by stunting. METHODS: We used longitudinal data from children aged 6 wk to 24 mo (n = 12,155) enrolled in the ZVITAMBO (Zimbabwe Vitamin A for Mothers and Babies) trial...

CONTEXT: Low 25-hydroxyvitamin D [25(OH)D] concentrations have been consistently associated with excess mortality in epidemiological studies, but this association could be due to confounding by health impairments going along with low 25(OH)D levels. An association of vitamin D related genetic variants with all-cause mortality could strengthen the claims of causality, because this association is assumed to be unaffected by confounding. OBJECTIVE: To assess the associations of low 25(OH)D with mortality in the presence or absence of genetic variants in the vitamin D pathway...

The combination of AF and coronary artery disease not only is a common clinical setting, it is also a complex setting to deal with anticoagulation and antiplatelet therapy, and it is associated with significantly higher mortality rates. Unfortunately, there are no sufficient data available to optimally guide clinical practice in such settings. This review focuses specifically on newer oral anticoagulants (NOACs) associated with dual antiplatelet therapy (DAPT) in patients with coronary artery disease undergoing percutaneous coronary intervention (PCI)...
