BACKGROUND: Hospital-acquired pressure injuries (HAPIs) typically develop following critical illness due to immobility and suboptimal perfusion. Vitamin D helps to maintain epithelial cell integrity, particularly at barrier sites such as skin. It is unclear whether vitamin D status is a modifiable risk factor for HAPIs in critically ill patients. Our goal was to investigate the relationship between admission 25-hydroxyvitamin D (25OHD) levels with the development of HAPIs in surgical intensive care unit (ICU) patients...

Intracranial hemorrhage due to vitamin K deficiency is a serious disease that can lead to morbidity, mortality, and mental retardation. Our goal in this study is to determine the frequency of VKORC1-1639 G>A polymorphism in patients who have undergone intracranial hemorrhage due to vitamin K deficiency bleeding (VKDB). To study VKORC1-1639 G>A polymorphism, blood was drawn from patients (n = 51, age 8:0 ± 6:5 years) followed at the Pediatric Neurology and Hematology section, Faculty of Medicine, Erciyes University, between 1990 and 2016, diagnosed with VKDB as idiopathic or from patients diagnosed with intracranial hemorrhage due to secondary vitamin K deficiency and also from volunteers (n = 51, age 11 ± 4...

BACKGROUND: Thrombotic disorders remain one of the leading causes of death in the Western world. Dabigatran appeared as an alternative to warfarin for anticoagulation in the treatment of atrial fibrillation (AF). The risk associated with bleeding due to its use has been documented in several randomized clinical trials, but no large study has examined in detail the risk of bleeding during dental extraction and other dental procedures involving bleeding. OBJECTIVE: To compare the intensity of bleeding in individuals taking dabigatran or vitamin K antagonist (warfarin) and undergoing dental procedures...

The pleiotropic biochemical and antioxidant functions of vitamin C have sparked recent interest in its application in intensive care. Vitamin C protects important organ systems (cardiovascular, neurologic and renal systems) during inflammation and oxidative stress. It also influences coagulation and inflammation; its application might prevent organ damage. The current evidence of vitamin C's effect on pathophysiological reactions during various acute stress events (such as sepsis, shock, trauma, burn and ischemia-reperfusion injury) questions whether the application of vitamin C might be especially beneficial for cardiac surgery patients who are routinely exposed to ischemia/reperfusion and subsequent inflammation, systematically affecting different organ systems...

Vitamin D (VD) is a steroid prohormone that regulates the body's calcium and phosphate levels in bone mineralization. It is also well described as a fat-soluble vitamin playing an important role in immunomodulation, regulation of cytokines, and cell proliferation. Thus, VD is a powerful hormone with pleiotropic effects, which acts to maintain optimal health. Recent studies demonstrate that VD deficiency is associated with the development of cardiovascular diseases, autoimmune disorders, and various types of cancer, each associated with increased mortality rates...

Ischemia-reperfusion (I/R)-induced oxidative stress is one of the main mechanisms of tissue injury after cardiac arrest (CA). A decrease in antioxidant defenses may contribute to I/R injury. The present study aims to investigate the influence of mild therapeutic hypothermia (MTH) on levels of nonenzymatic antioxidants after CA. We investigated antioxidant levels at 6, 12, 36, and 72 hours after CA in central venous blood samples of patients admitted to intensive care. The sample consisted of 31 patients under controlled normothermia (36°C) and 11 patients treated with 24 hours of MTH (33°C)...

INTRODUCTION: "Major burn" is used to describe a person who suffers thermal damage affecting more than 30% of his/her total body surface area (TBSA). The secondary hypercatabolism causes lean body mass loss and delayed wound healing. OBJECTIVE: To describe and analyze the results of implementing a nutritional support protocol for pediatric burn patients hospitalized in the intensive care unit in the first 6 weeks. POPULATION AND METHODS: Analytical, prospective, observational, and longitudinal design...

PURPOSE: Low vitamin D blood levels are related to many clinical outcomes in children with critically illness. However, the relationship of it and septic shock has not been systematically analyzed. The objective of this review was to evaluate the effect of vitamin D on septic shock and predict if vitamin D administration can improve prognosis of it. MATERIALS AND METHODS: Online databases were searched up to June 1st, 2017 for studies on the relation of vitamin D deficiency (VDD) and clinical outcomes on septic shock in children with critical illness...

Background Vitamin D deficiency in mothers and neonates is being recognised increasingly as a leading cause of many adverse health effects in the newborn infant, including sepsis. Methods A prospective observational study was conducted at a tertiary care Paediatric teaching hospital in northern India to assess vitamin D deficiency as a possible risk factor for late-onset sepsis (LOS) in term and late preterm neonates and also to examine the correlation between maternal and infant vitamin D levels during the neonatal period...

AIM: Intrahepatic cholestasis of pregnancy (ICP) is a unique hepatic disorder of pregnancy and is related to adverse maternal and perinatal outcomes. The pathogenesis of the disease is not clear and appears to be multifactorial. There is increasing evidence that vitamin D (Vit D) plays a role in hepatobiliary homeostasis and in various liver diseases. We aimed to investigate the association between serum Vit D level and ICP. METHODS: A total of 40 pregnant women with ICP and 40 healthy pregnant women were included in this controlled cross-sectional study...

BACKGROUND: Vitamin C has anti-oxidant properties and acts as a co-factor for a number of enzymes. Hypovitaminosis C has been associated with bleeding, endothelial dysfunction and death. The prevalence of hypovitaminosis C is unknown in Australian hospitalized patients and its clinical relevance is uncertain. AIMS: To determine prevalence, characteristics and clinical outcomes of hospitalized patients with hypovitaminosis C. METHODS: This observational study included general-medical inpatients in a tertiary-level hospital in Australia...

Background/Aims: Vitamin D modulates innate and adaptive immune responses, and vitamin D deficiency is associated with increased mortality in hospitalized patients with pneumonia. We evaluated the prevalence of vitamin D deficiency in Korean patients with acute respiratory distress syndrome (ARDS) and its effect on the clinical outcomes of ARDS. Methods: We retrospectively analyzed the data of 108 patients who had a measured serum level of 25-hydroxy vitamin D3 (25(OH)D3) at the time of diagnosis with ARDS...

Hypovitaminosis D has been identified as a predictor of mortality in human beings, dogs, cats and foals. However, the immunomodulatory effects of vitamin D in critically ill dogs has not been evaluated. The aim of this study was to evaluate the effect of calcitriol on cytokine production from whole blood collected from critically ill dogs in vitro. Twelve critically ill dogs admitted to a veterinary intensive care unit (ICU) were enrolled in a prospective cohort study. Whole blood from these dogs was incubated with calcitriol (2×10-7 M) or ethanol (control) for 24h...

OBJECTIVES: Vitamin D is an important component of bone metabolism. Skin cells synthesize vitamin D when exposed to the sun. However, prolonged sun exposure damages the skin and increases the risk for skin cancer. The objective is to evaluate and compare the attitudes and recommendations of family doctors, dermatologists, and endocrinologists on exposure to the sun and vitamin D. METHODS: In a cross-sectional study, a questionnaire was completed by personal interview in a study population of 78 family doctors, 21 dermatologists, and 22 endocrinologists...

The measurement of vitamin D-binding protein (VDBP) by immunoassay has been confounded by variable antibody recognition of the Gc1s, Gc1F and Gc2 phenotypes. This has led to spurious conclusions regarding vitamin D status in different ethnic groups. In order to overcome these problems there is a requirement for VDBP antibodies that are unaffected by phenotype status. Here we report the generation and testing of three monoclonal antibodies to VDBP which recognise linear epitopes and are unaffected by vast molar excesses of synthetic peptides spanning these phenotypic domains...
