Interstitial cystitis (IC), also known as painful bladder syndrome (PBS), is a debilitating chronic condition that afflicts over 3 million women above the age of 18 in the U.S., and most patients fail to respond to current treatment options. Mast cells have previously been implicated as both a diagnostic and prognostic marker in IC/PBS. Patients with IC/PBS have been shown to have elevated levels of IL-33, a cytokine released in response to tissue insult, in their urine. We hypothesize that mast cell-mediated inflammation induced from IL-33 may play an important role in initiating pain and inflammation in IC/PBS...

OBJECTIVE: Patients with benign paroxysmal positional vertigo (BPPV) can have vitamin D deficiency, which is a cause of abnormal bone turnover. Several studies have established a relationship between osteoporosis and BPPV. The World Health Organization Fracture Risk Assessment Tool, widely known as FRAX® (http://www.shef.ac.uk/FRAX), is a computer-based algorithm for assessing fracture risk. No direct comparison has been made between the FRAX scores of patients with BPPV and controls...

BACKGROUND: Bone healing and assessment of the state of bone bridging is an important part of clinical orthopedics, whether for fracture healing or for follow up of osteotomy procedures. Tibial tuberosity advancement (TTA) is designed to restore stability in cruciate deficient stifle joints by advancing the tuberosity while creating an osteotomy gap. The current study aims to: 1) compare three different imaging modalities to assess bone healing: ultrasound, radiographs and computed tomography (CT) and, to 2) compare the effect of a gelatinous matrix (GM) versus a demineralized bone matrix mix (DBM mix) on bone healing and bridging of this osteotomy gap in 10 otherwise healthy client-owned dogs with cranial cruciate ligament insufficiency...

Pregnant women in Asia, the Middle East, Africa and Latin America are at risk of vitamin D deficiency (VDD) and prevalence throughout these regions are among the highest, globally. Maternal VDD has been associated with increased risk of a number of adverse maternal and neonatal health outcomes, yet research from developing countries is limited. We assessed the associations of maternal VDD during pregnancy with adverse health outcomes by synthesizing the literature from observational studies conducted in developing countries...

OBJECTIVES: Multiple invasive group A streptococcal (GAS) infections were reported to public health by a skilled nursing facility (Facility A) in Illinois between May 2014 and August 2016. Cases continued despite interventions including antibiotic prophylaxis for all residents and staff. Two other geographically close facilities reported contemporaneous outbreaks of GAS. We investigated potential reasons for ongoing transmission. METHODS: We obtained epidemiologic data from chart review of cases and review of facility and public health records from previous investigations into the outbreak...

BACKGROUND: Stereotactic radiosurgery (SRS) is used to manage patients with Cushing's disease (CD) who have failed surgical/medical management. As many patients with recurrent/persistent CD lack an identifiable adenoma on neuro-imaging, whole-sellar SRS has been increasingly employed. We therefore sought to define the outcomes of patients undergoing whole-sellar SRS. METHODS: An international, multicenter, retrospective cohort-design was used to define clinical/endocrine outcomes for patients undergoing whole-sellar SRS for CD...

BACKGROUND: Vitamin D (vitD) deficiency is prevalent among childhood hematopoietic stem cell transplantation (HSCT) recipients and associated with inferior transplant survival at 100 days after transplantation. Achieving and maintaining therapeutic vitD levels in HSCT recipients is extremely challenging in the first 3-6 months after transplant due to poor compliance in the setting of mucositis, and concomitant use of critical transplant drugs that interfere with vitD absorption. We sought to evaluate the safety and efficacy of a single, ultra-high dose of vitD given prior to childhood HSCT to maintain levels in a therapeutic range during the peri-transplantation period...

Biosynthetic precursors of NAD+ can replenish a decreased cellular NAD+ pool and, supposedly via sirtuin (SIRT) deacetylases, improve mitochondrial function. We found decreased hepatic NAD+ concentration and downregulated biosynthesis in Bcs1lp.S78G knock-in mice with respiratory chain complex III deficiency and mitochondrial hepatopathy. Aiming at ameliorating disease progression via NAD+ repletion and improved mitochondrial function, we fed these mice nicotinamide riboside (NR), a NAD+ precursor. A targeted metabolomics verified successful administration and suggested enhanced NAD+ biosynthesis in the treated mice, although hepatic NAD+ concentration was unchanged at the end point...

Vitamin D (vit-D) deficiency is highly prevalent in patients with gastro-entero-pancreatic neuroendocrine tumors (GEP-NET) and has been linked to reduced overall survival. We here assessed the vit-D status in 183 patients with GEP-NET at the time of their first presentation in the ARDEN NET Centre. We further examined the effect of simple advice to increase vit-D intake using over-the-counter vit-D preparations [colecalciferol (Vit-D3), 1,000-2,000 units/day], over a prospective observation period of 24 mo...

OBJECTIVES: Infection is an important cause of morbidity and mortality after lung transplantation. Immunoglobulins are part of both seromucous (IgA) and serum (IgG) infection defense mechanisms. We therefore hypothesized that lower pretransplant IgA levels would be associated with more early post-lung transplant seromucous infections and greater mortality independent of IgG. METHODS: From January 2000 to July 2010, 538 patients undergoing primary lung transplantation had pretransplant IgA (n = 429) and IgG (n = 488) measured as a clinical routine...

We developed a smart phone application to measure participants' food-reward perceptions and eating behavior in their naturalistic environment. Intensity ratings (0 - not at all to 10 - very strongly) of perceived anticipation of food (wanting) and food enjoyment at endpoint of intake (liking) were recorded as they occurred over a period of 14 days. Moreover, food craving trait, implicit and explicit attitude towards healthy food, and body composition were assessed. 53 participants provided complete data. Participants were classified by percentage of body fat; 33 participants with lower body fat (L-group) and 20 with higher body fat (H-group; ≥25% body fat for males and ≥32% for females)...

BACKGROUND: Vascular damage and primary graft dysfunction increase with prolonged preservation times of transplanted donor lungs. Hence, storage and conservation of donated lungs in protein-free, dextran-containing electrolyte solutions, like Perfadex, is limited to about 6 hours. We hypothesized that transplanted lungs are protected against neutrophil-mediated proteolytic damage by adding α1 -anti-trypsin (AAT), a highly abundant human plasma proteinase inhibitor, to Perfadex. METHODS: A realistic clinically oriented murine model of lung transplantation was used to simulate the ischemia-reperfusion process...

BAckground: The human immunodeficiency virus type 1 (HIV-1) is an infectious viral agent that gradually extinguishes the immune system, resulting in acquired immune deficiency syndrome (AIDS). The aim of this study was to construct an RNA-positive control based on armored (AR) RNA technology, using HIV-1 RNA as a model. Methods: The MS2 maturase, a coat protein gene (at positions 1765 to 1787) and HIV-1 pol gene were cloned into pET-32a plasmid. The prepared plasmid was transformed into Escherichia coli strain BL2 (DE3), and the expression of the construct was induced by 1 mM of isopropyl-L-thio-D-galactopyranoside (IPTG) at 37 °C for 16 h to obtain the fabricated AR RNA...

Animal models of mild traumatic brain injury (mTBI) provide opportunity to examine the extent to which dietary interventions can be used to improve recovery after injury. Animal studies also suggest that matrix metalloproteinases (MMPs) play a role in tissue remodeling post-TBI. Because dietary zinc (Zn) improved recovery in non-blast mTBI models, and the MMPs are Zn-requiring enzymes, we evaluated the effects of low- and adequate Zn diets on MMP expression and behavioral responses, following exposure to a single blast...

BACKGROUND Cholesteryl ester storage disease (CESD), also known as lysosomal acid lipase deficiency (LAL-D), is a rare autosomal-recessive inheritable lysosomal storage disease. Since 2015, a causal treatment with sebelipase alfa, which replaces the missing LAL enzyme, has been approved. We report a fatal course of LAL-D in a female patient. CASE REPORT In 1979, CESD was first diagnosed in a 13-year-old female with marked hepatomegaly. At that time, no specific treatment for CESD was available and the spontaneous course of the disease had to be awaited...
