Understanding the variables that influence microbiome studies is critical for successful translational research. Inflammatory bowel disease (IBD) is a complex group of diseases that can present at multiple locations within the Gastrointestinal tract. Here, using the FAMISHED study cohort, we aimed to investigate the relationship between IBD condition, IBD disease location, and the microbiome.

Background: Volatile organic compounds (VOCs) are hydrocarbons that originate within different healthy and diseased tissues. VOCs can be secreted into the circulation and then excreted in the urine and faeces. In the lungs, VOCs are locally produced and can be detected in exhaled breath.

Objective: The aim of this study was to describe individuals seeking care for injury at a major emergency department (ED) in southern Puerto Rico in the months after Hurricane Maria on September 20, 2017.

Methods: After informed consent, we used a modified version of the Natural Disaster Morbidity Surveillance Form to determine why patients were visiting the ED during October 16, 2017-March 28, 2018. We analyzed visits where injury was reported as the primary reason for visit and whether it was hurricane-related.

Background: In Fabry nephropathy, podocyturia is an early event that may lead to glomerulosclerosis and chronic kidney disease. The glycocalyx is a potential podocyte damaged compartment in glomerulopathies. We investigated glycocalyx podocalyxin in urinary detached podocytes compared with cytoplasmic synaptopodin.

Glomerular diseases are one of the most frequent causes of chronic kidney disease, focal and segmental glomerulosclerosis being one of the commonest glomerulopathies. However, the etiology of this glomerular entity, which merely depicts a morphologic pattern of disease, is often not established and, in most of the patients, remains unknown. Nephrologists tend to assume focal and segmental glomerulosclerosis as a definitive diagnosis.

The purpose of this investigation was to develop an exploratory two-step level A IVIVC for three telmisartan oral immediate release formulations, the reference product Micardis, and two generic formulations (X1 and X2). Correlation was validated with a third test formulation, Y1. Experimental solubility and permeability data were obtained to confirm that telmisartan is a class II compound under the Biopharmaceutic Classification System.

Background: Podocyturia may determine the evolution to podocytopenia, glomerulosclerosis, and renal failure. According to the Oxford classification of IgA nephropathy (IgAN), the S1 lesion describes glomerulosclerosis. Urokinase-type plasminogen activator receptor (uPAR) participates in podocyte attachment, while CD80 increases in glomerulosclerosis.

. Despite enzyme replacement therapy, Fabry nephropathy still progresses. Podocyturia is an irreversible event that antedates proteinuria and leads to chronic renal failure.

IgA nephropathy is the most frequent cause of primary glomerulonephritis, portends erratic patterns of clinical presentation, and lacks specific treatment. In general, it slowly progresses to end-stage renal disease. The clinical course and the response to therapy are usually assessed with proteinuria and serum creatinine.

Background: Proteinuria suggests kidney involvement in Fabry disease. We assessed podocyturia, an early biomarker, in controls and patients with and without enzyme therapy, correlating podocyturia with proteinuria and renal function.

Methods: Cross-sectional study (n = 67): controls (Group 1, n = 30) vs.

Background: Certain glomerulopathies are associated with increased levels of CD80 (B7-1). We measured the urinary excretion of CD80, podocyturia and proteinuria in controls and in subjects with Fabry disease either untreated or on enzyme replacement therapy (ERT).

Methods: Cross-sectional study including 65 individuals: controls (n = 20) and Fabry patients (n = 45, 23 of them not on ERT and 22 on ERT).

Background: In transplantation immunosuppression enhances the appearance of opportunist infections. An ideal balance between the prevention of rejection, the lowest risk of infections and the highest rates of graft survival is a continuous challenge. Lower doses of immunosuppression may diminish the risk of infections, metabolic and hemodynamic complications or even of malignancy, but may expose patients to episodes of acute rejection.

No specific or efficient treatment exists for Alport syndrome, an X-linked hereditary disease caused by mutations in collagen type IV, a crucial component of the glomerular basement membrane. Kidney failure is usually a major complication of the disease, and patients require renal replacement therapy early in life. Microhematuria and subsequently proteinuria are hallmarks of kidney involvement, which are due to primary basement membrane alterations that mainly cause endothelial thrombosis and podocyte contraction and ulterior irreversible detachment.

Unlabelled: The purpose of this study is to evaluate the characteristics of patients admitted to Bella Vista Hospital in Mayagüez with a diagnosis of infected skin ulcer, the most common microorganisms recovered in cultures, and their antimicrobial sensitivity patterns.

Methods: All patients discharged with the diagnosis of infected skin ulcer from January 1 through December 31, 2012 were selected. Following variables were extracted: sex, age, hospital stay, morbid conditions, antibiotics used, microorganisms identified on cultures and sensitivity of microorganisms to different antimicrobials.

Unlabelled: Procalcitonin (PCT) has emerged as a marker of infection, a frequent complication in hemodialysis (HD). We analyzed PCT levels in chronic non-acutely infected HD subjects, assessed its correlation with inflammatory and nutritional markers and propose a PCT reference value for non-infected HD patients. In an observational cross-sectional study, 48 chronic HD patients and 36 controls were analyzed.

Primary glomerulonephritis stands as the third most important cause of end-stage renal disease, suggesting that appropriate treatment may not be as effective as intended to be. Moreover, proteinuria, the hallmark of glomerular damage and a prognostic marker of renal damage progression, is frequently resistant to thorough control. In addition, proteinuria may be the common end pathway in which different pathogenetic mechanisms may converge.

Background: Cardiovascular disease is the leading cause of morbidity and mortality in hemodialysis (HD) patients, the main etiologies being diabetes and hypertension. Cardiac and inflammatory biomarkers are usually employed to assess risk or damage, or during follow-up. Proteinuria is considered a strong predictor of morbidity, a cause of inflammation, oxidative stress, hemodynamic alteration, and progression of chronic kidney disease.

Background: In chronic kidney disease (CKD), accurate estimation of the glomerular filtration rate (GFR) is mandatory. Gold standard methods for its estimation are expensive and time-consuming. We compared creatinine- versus cystatin C-based equations to measure GFR, employing (99m)Tc-DTPA scintigraphy as the gold standard.

Article Synopsis
  • - Adiponectin levels show varying cardiovascular effects based on body mass index (BMI), with higher levels linked to increased cardiovascular risk in nonobese individuals, while obese patients may have lower mortality despite low adiponectin.
  • - The study analyzed 52 chronic hemodialysis patients divided into three BMI groups, revealing significant correlations between adiponectin and other markers like Pro-BNP and troponin T, as well as shifts in nutritional status and insulin resistance as BMI changes.
  • - Results indicate that low-BMI individuals had worse nutritional status and higher levels of Pro-BNP and adiponectin, while obesity led to a hypoadiponectinemia that promotes harmful cardiac adaptations, suggesting adiponectin's

Protein-energy wasting (PEW) and inflammation are usually common and concurrent conditions in maintenance dialysis patients and associated with poor prognosis. Low appetite and hypercatabolic states are common features. In dialysis patients, the former has been suggested to be secondary to inflammation; however, the evidence is not conclusive.

Background: We assessed the relationship between pro-brain natriuretic peptide (pro-BNP), troponin T (TropT) and nutritional status.

Methods: A total of 48 chronic hemodialysis patients were grouped according to the presence [group A (GA); n = 24] or not [group B (GB)] of cardiovascular disease.

Results: Compared to GB subjects, GA subjects were older, had been on hemodialysis for a longer period and had higher prevalences of vascular grafts, hypertension and elevated C-reactive protein (CRP) [GA vs.
