Heart failure with a preserved ejection fraction (HFpEF) is increasingly prevalent and a leading cause of morbidity and mortality worldwide. HFpEF has a complex pathophysiology, with recent evidence suggesting that an interaction of cardiovascular and noncardiovascular comorbidities (e.g. obesity, hypertension, diabetes, coronary artery disease, and chronic kidney disease) induces an inflammatory state that eventually leads to myocardial structural and functional alterations. Current ACCF/AHA guidelines suggest incorporation of biomarkers along with clinical and imaging tools to establish the diagnosis and disease severity in heart failure (HF)...

The current view of type 1 diabetes (T1D) is that it is an immune-mediated disease where lymphocytes infiltrate the pancreatic islets, promote killing of beta cells and cause overt diabetes. Although tissue resident immune cells have been demonstrated in several organs, the composition of lymphocytes in human healthy pancreatic islets have been scarcely studied. Here we aimed to investigate the phenotype of immune cells associated to human islets of non-diabetic organ donors. A flow cytometry analysis of isolated islets from perfused pancreases (n=38) was employed to identify alpha, beta, T, NK and B cells...

PURPOSE: Obesity and breast density are both associated with an increased risk of breast cancer and are potentially modifiable. Weight loss surgery (WLS) causes a significant reduction in the amount of body fat and a decrease in breast cancer risk. The effect of WLS on breast density and its components has not been documented. Here, we analyze the impact of WLS on volumetric breast density (VBD) and on each of its components (fibroglandular volume and breast volume) by using three-dimensional methods...

: Recent studies indicate that inflammasomes serve as intracellular machinery to initiate classical cytokine-mediated inflammatory responses and play a crucial role in the pathogenesis of cardiovascular diseases. However, whether or not the activation of endothelial inflammasomes directly causes cell dysfunction or tissue injury without recruitment of inflammatory cells is unknown. We explored the role of endothelial cell inflammasome activation in mediating tight junction disruption, a hallmark event of endothelial barrier dysfunction leading to endothelial hyperpermeability in diabetes...

The cause and effect relationship between diabetes and zinc is complex and unclear. This animal study has examined the potential of zinc supplementation in beneficial modulating hyperglycemia, insulin secretion, and metabolic abnormalities associated with diabetes. The study was conducted in streptozotocin-induced diabetic rats. Groups of hyperglycemic rats were subjected to dietary interventions for 6 weeks with zinc supplementation (5 times and 10 times the normal level). Supplemental-zinc-fed diabetic groups showed significant control on hyperglycemia and hypoinsulinemia...

BACKGROUND: Diabetic retinopathy (DR) is regarded as a major cause of preventable blindness, which can be detected and treated if the cases are identified by screening. Screening for DR is therefore being practiced in developed countries, and tele screening has been a prominent model of delivery of eye care for screening DR. AIM: Our study has been designed to provide inputs on the suitability of a computer-assisted DR screening solution, for use in a larger prospective study...

Introduction Turkey has one of the largest treated end-stage renal disease (ESRD) patient populations in Europe (N = 66,711). In 2013, the international Dialysis Outcomes and Practice Patterns Study (DOPPS), a prospective study of hemodialysis (HD) practices and outcomes, initiated data collection in Turkey. Here we provide comparisons of HD patients in DOPPS-Turkey with other international regions and with patients in the Registry of Turkish Nephrology, Dialysis and Transplantation. Methods DOPPS-Turkey study sites were randomly selected from all Turkish HD units treating ≥25 in-center chronic HD patients...

We performed a multisite study to evaluate demographic and clinical conditions as potential modifiers of the particulate matter (PM)-mortality association. We selected 228,619 natural deaths of elderly persons (ages ≥65 years) that occurred in 12 Italian cities during the period 2006-2010. Individual data on causes of death, age, sex, location of death, and preexisting chronic and acute conditions from the previous 5 years' hospitalizations were collected. City-specific conditional logistic regression models were applied within the case-crossover "time-stratified" framework, followed by random-effects meta-analysis...

Over the past two decades, studies have widely examined the effectiveness of pay-for-performance (P4P) programs by conducting biochemical tests and assessing complications; however, the reported effectiveness of such programs among participants selected through purposeful sampling is controversial. Therefore, the objective of the current study was to analyze the effectiveness of a P4P program on patients' prognoses, including hospitalization for chronic diabetic complications, and all-cause mortality during specific follow-up years by using a nationwide population-based database in Taiwan...

Nephrogenic diabetes insipidus is a condition characterized by polyuria with dilute urine due to the inability of the principal cells of the renal collecting ducts to respond to antidiuretic hormone and concentrate urine. Nephrogenic diabetes insipidus can be drug induced, and several chemotherapeutic agents have been reported to cause it. Bendamustine is a traditional chemotherapeutic agent being studied for treatment for relapsed systemic AL amyloidosis. We report a case of a 59-year-old man with AL amyloidosis who developed partial nephrogenic diabetes insipidus after receiving bendamustine for treatment of AL amyloidosis...

BACKGROUND: Neonatal hypoglycaemia is common, affecting up to 15% of newborns, and can cause brain damage. Currently, there are no strategies, beyond early feeding, to prevent neonatal hypoglycaemia. Our aim was to determine a dose of 40% oral dextrose gel that will prevent neonatal hypoglycaemia in newborn babies at risk. METHODS AND FINDINGS: We conducted a randomised, double-blind, placebo-controlled dose-finding trial of buccal dextrose gel to prevent neonatal hypoglycaemia at two hospitals in New Zealand...

Familial partial lipodystrophy type 2 (FPLD2) is a rare disorder associated with LMNA gene mutations. It is usually marked by loss of subcutaneous fat on the limbs and trunk and severe insulin resistance. Scattered reports have indicated that Roux-en-Y bypass helps to control the diabetes mellitus in these patients. We present here a very unusual patient with FPLD2 who had life-threatening retroperitoneal and renal fat accumulation accompanied by bilateral renal cancers. Following cryotherapy of one renal cancer and a contralateral nephrectomy with debulking of the retroperitoneal fat, Roux-en-Y gastric bypass (RYGB) has successfully controlled the disease for 3 years...

Diabetic retinopathy (DR), a leading cause of acquired vision loss, is a microvascular complication of diabetes. While traditional risk factors for diabetic retinopathy including longer duration of diabetes, poor blood glucose control, and dyslipidemia are helpful in stratifying patient's risk for developing retinopathy, many patients without these traditional risk factors develop DR; furthermore, there are persons with long diabetes duration who do not develop DR. Thus, identifying biomarkers to predict DR or to determine therapeutic response is important...

Diabetic retinopathy is caused by the retinal micro vasculature which may be formed as a result of diabetes mellitus. Blindness may appear as a result of unchecked and severe cases of diabetic retinopathy. Manual inspection of fundus images to check morphological changes in microaneurysms, exudates, blood vessels, hemorrhages, and macula is a very time-consuming and tedious work. It can be made easily with the help of computer-aided system and intervariability for the observer. In this paper, several techniques for detecting microaneurysms, hemorrhages, and exudates are discussed for ultimate detection of nonproliferative diabetic retinopathy...

In rare instances, recipients of organ transplants from human T-lymphotropic virus type I- (HTLV-I-) positive donors reportedly developed neurologic symptoms due to HTLV-I-associated myelopathy (HAM). We present herein two cases of HAM associated with renal transplantation from HTLV-I seropositive living-donors. The first patient was a 42-year-old woman with chronic renal failure for twelve years and seronegative for HTLV-I. She underwent renal transplantation with her HTLV-I seropositive mother as the donor, and she developed HAM three years after the transplantation...

Background. Cardiovascular disease (CVD) is one of the leading causes of death in Saudi Arabia. Saudi women in particular are more susceptible as there are sociocultural restrictions on female physical activities that may lead to high prevalence of CVD risks, especially obesity, and physical inactivity. This study aims to systematically review the published articles related to the prevalence of CVD risk among women in Saudi Arabia. The search strategy covers all published articles that assess the risk factor of CVD in Saudi Arabia from January 2000 to December 2015, using the following sources: Medline, Embase, and PsycINFO...

Mucor fungus infection is a rare opportunistic infection, rapidly progressive and often fatal in immunocompromised patients, or in patients with chronic debilitating diseases. We report six cases of trauma patients with mucormycosis. Three had severe thermal burns, one of them with a medical history of diabetes mellitus. The other three patients suffered from severe soft tissue injuries caused by traffic accidents. In all cases there had been spontaneous exposure and contact of the wounds with soil. During hospitalization, fungi cultures and/or biopsies of all wounds were performed and all resulted positive...

BACKGROUND: The results of the EMPA-REG-OUTCOME trial on type 2 diabetic patients at high risk for prior cardiovascular events showed that empagliflozin produces a remarkable reduction in the rates of hospitalization for heart failure (35%), cardiovascular death (38%), and all-cause death (32%). This unexpected cardio-protective action cannot be accounted for by the improvement of "classical" cardiovascular risk factors. AIMS: This review aims at summarizing current knowledge on the cardiovascular action of SGLT2 inhibitors and discuss the different hypotheses formulated to explain the results of the EMPA-REG-OUTCOME-study...

OBJECTIVES: Sulfonylureas have been inconsistently associated with increased cardiovascular mortality in patients with type 2 diabetes mellitus. However, there are no existing studies of long-term risk in South Asian and Chinese populations. Our objective was to determine whether sulfonylureas are associated with increased mortality or cardiovascular disease in a population cohort of South Asian, Chinese and other Canadian patients with incident diabetes. METHODS: We studied a population-based cohort of adults 35 years of age or older who had diabetes and had been diagnosed between April 2004 and March 2014 by using administrative databases from British Columbia...
