Highly effective decontamination in a hospital environment: An easy-to-operate, low-cost prototype.

Healthcare-associated infections (HAI) are illnesses acquired during healthcare and are often the most important adverse event during healthcare. With the aim of increasing the effectiveness of disinfection/decontamination processes in the health service with safe and not promote microbial resistance, we propose the development of portable equipment associated with type C ultraviolet light (UVC). The efficiency of the irradiance emitted by the equipment (at dosages 3.

Application of H HR-MAS NMR-Based Metabolite Fingerprinting of Marine Microalgae.

Natural products from the marine environment as well as microalgae, have been known for the complexity of the metabolites they produce due to their adaptability to different environmental conditions, which has been an inexhaustible source of several bioactive properties, such as antioxidant, anti-tumor, and antimicrobial. This study aims to characterize the main metabolites of three species of microalgae (, and ), which have important applications in the biofuel and nutrition industries, by H High-resolution magic angle spinning nuclear magnetic resonance (H HR-MAS NMR), a method which is non-destructive, is highly reproducible, and requires minimal sample preparation. Even though the three species were found in the same ecosystem and a superior production of lipid compounds was observed, important differences were identified in relation to the production of specialized metabolites.

Vitamin D status and COVID-19 prevention in a worker subgroup in Italy.

Background: Low levels of vitamin D are widespread in the world's population and associated with sun exposure, genetics, and lifestyles. Office workers in different occupational sectors seem more vulnerable than others. Scientific evidence reports a contribution of vitamin D in resistance to infections, opening to supplementation as a preventive action against pathogens, including SARS-CoV-2.

Relationship between Residual Urine Output and Type of Dialysis with FGF23 Levels.

Several studies investigated the role of fibroblast growth factor 23 (FGF23) in the regulation of renal phosphate excretion in chronic kidney disease (CKD). However, patients with residual urine output (UO) seem to control their serum phosphorus levels better. Our aim was to determine whether FGF23 levels are influenced by dialysis modality and UO.

Piezoelectric harvesting of mechanical energy for redox chemistry.

Much work has been done in the utilization of mechanical force to enable chemical processes. However, this process is limited to thermal- and deformation-driven reactions. In fact, the transfer of energy in mechanical reactors can be quite inefficient, with energy lost to heat and mechanical deformation.

[Lymphocytic leukopenia in two patients affected by polycystic kidney disease waiting for renal transplantation].

Autosomal dominant polycystic kidney disease (ADPKD) is the most common hereditary kidney disease, responsible for 10% of patients on renal replacement therapy. The disease is well known to be associated with many extrarenal manifestations. Leukopenia may also be present, even if it is not commonly identified as a typical extrarenal manifestation.

The role of vitamin D in prevention OF COVID-19 and its severity: an umbrella review.

Background And Aim: Vitamin D is known to modulate immune response and its deficiency was associated with respiratory distress in patients hospitalized for pneumonia. Nevertheless, numerous reviews on vitamin D in COVID-19 patients have shown conflicting results, as previously reported also for other respiratory diseases (e.g.

[Slowing progression of chronic kidney disease in polycistic kidney disease patients with tolvaptan: from guidelines to clinical practice].

Autosomal dominant polycystic kidney disease (ADPKD) is the most common hereditary kidney disease and accounts for∼10% of patients on renal replacement therapy. In the last decade, no specific treatment was available and only preventive measures could be put in place to delay the onset of ESRD. Following the results of the TEMPO 3:4 study, tolvaptan was approved in many countries, for the purpose of slowing the progression of renal insufficiency.

Effects of virtual learning environments: A scoping review of literature.

The purpose of this scoping review is to isolate and investigate the existing data and research that identifies if the synchronous face-to-face visual presence of a teacher in a virtual learning environment (VLE) is a significant factor in a student's ability to maintain good mental health. While the present research on this explicit interaction among VLE implementation and student mental health is limited, the material suggests a framework for strong utilization of VLEs. Overall, our research has shown that authentic, high quality VLEs are ones that have as their primary focus the communication between students and their teachers and between students and their peers.

Combination of biomarker with clinical risk factors for prediction of severe acute kidney injury in critically ill patients.

Background: Acute kidney injury (AKI) occurs commonly in the intensive care unit (ICU). Insulin-like growth factor-binding protein 7 (IGFBP7) and tissue inhibitor of metalloproteinase-2 (TIMP-2), known as [TIMP-2] x [IGFBP7] (NephroCheck), have been identified as novel biomarkers for the prediction of AKI risk. However, the effective use of disease biomarkers is indispensable from an appropriate clinical context.

Comanagement Strategy Between Academic Institutions and Community Practices to Reduce Induction Mortality in Acute Promyelocytic Leukemia.

Purpose: Acute promyelocytic leukemia (APL) is a curable leukemia with > 90% survival in clinical trials. Population-based studies from Sweden and US SEER data have shown long-term survival rates of 62% and 65.7%, with the lower rate being from a higher percentage of early deaths.

Differential effects of peritoneal and hemodialysis on circulating regulatory T cells one month post initiation of renal replacement therapy.

Backgroundː Chronic kidney disease stage G5 (CKD G5) patients show an activated but impaired immune system. One function of the FOXP3 regulatory T (Treg) cells is to preserve tolerance to self while maintaining the ability to fight infectious agents. The aim of this pilot study is to evaluate longitudinal changes in Treg cells before and 1 month after the first dialysis treatment.

Urinary [TIMP-2] × [IGFBP7] and serum procalcitonin to predict and assess the risk for short-term outcomes in septic and non-septic critically ill patients.

Background: Biomarkers can play a critical role by facilitating diagnosis and stratification of disease, as well as assessment or prediction of disease severity. Urinary tissue inhibitor of metalloproteinase-2 and insulin-like growth factor binding protein 7 product ([TIMP-2] × [IGFBP7]) predict the development and progression of AKI and recently procalcitonin (PCT), a widely used biomarker for sepsis diagnosis and management, has been associated with AKI occurrence in ICU patients. To assess combinations of [TIMP-2] × [IGFBP7] and PCT results for prediction and risk stratification of short-term outcomes in septic and non-septic patients, a retrospective cohort analysis of critically ill patients was performed in a multidisciplinary ICU.

Availability of all-trans retinoic acid and support systems for management of acute promyelocytic leukemia in Michigan and Louisiana, USA.

Acute promyelocytic leukemia (APL) is a subtype of acute myeloid leukemia with high induction mortality in the general population despite evidence of high cure rates in the clinical trials. Aggressive supportive care is essential for ideal management of these patients. We conducted a survey to collect data on these important issues required for successful treatment/outcome of APL patients from two states (Michigan and Louisiana) due to their low one-year survival rate among the Surveillance, Epidemiology, and End Results registries.

Acute rejection in kidney transplantation and the evaluation of associated polymorphisms (SNPs): the importance of sample size.

Background Acute rejection (AR) is one of the most frequent complications after kidney transplantation (KT). Scientific evidence reports that some single-nucleotide polymorphisms (SNPs) located in genes involved in the immune response and in the pharmacokinetics and pharmacodynamics of immunosuppressive drugs are associated with rejection in renal transplant patients. The aim of this study was to evaluate some SNPs located in six genes: interleukin-10 (IL-10), tumor necrosis factor (TNF), adenosine triphosphate-binding cassette sub-family B member 1 (ABCB1), uridine diphosphate glucuronosyltransferase family 1 member A9 (UGT1A9), inosine monophosphate dehydrogenase 1 (IMPDH1) and IMPDH2.

Tenogenic differentiation protocol in xenogenic-free media enhances tendon-related marker expression in ASCs.

Adipose-derived stem cells (ASCs) are multipotent and immune-privileged mesenchymal cells, making them ideal candidates for therapeutic purposes to manage tendon disorders. Providing safe and regulated cell therapy products to patients requires adherence to good manufacturing practices. To this aim we investigated the in vitro tenogenic differentiation potential of ASCs using a chemically defined serum-free medium (SF) or a xenogenic-free human pooled platelet lysate medium (hPL) suitable for cell therapy and both supplemented with CTGF, TGFβ-3, BMP-12 and ascorbic acid (AA) soluble factors.

A New Series of Sorbent Devices for Multiple Clinical Purposes: Current Evidence and Future Directions.

Adsorption is an extracorporeal technique utilized for blood purification. It complements convection and diffusion (the main modalities of solute removal). It involves the passage of blood (or plasma) through an adsorption cartridge, where solutes are removed by direct binding to the sorbent material.

Persistent decrease of renal functional reserve in patients after cardiac surgery-associated acute kidney injury despite clinical recovery.

Background: Cardiac surgery is a leading cause of acute kidney injury (AKI). Such AKI patients may develop progressive chronic kidney disease (CKD). Others, who appear to have sustained no permanent loss of function (normal serum creatinine), may still lose renal functional reserve (RFR).

A stromal cell population that inhibits adipogenesis in mammalian fat depots.

Adipocyte development and differentiation have an important role in the aetiology of obesity and its co-morbidities. Although multiple studies have investigated the adipogenic stem and precursor cells that give rise to mature adipocytes, our understanding of their in vivo origin and properties is incomplete. This is partially due to the highly heterogeneous and unstructured nature of adipose tissue depots, which has proven difficult to molecularly dissect using classical approaches such as fluorescence-activated cell sorting and Cre-lox lines based on candidate marker genes.

Biocompatibility and Cytotoxic Evaluation of New Sorbent Cartridges for Blood Hemoperfusion.

Background/aims: The use of adsorption cartridges for hemoperfusion (HP) is rapidly evolving. For these devices, the potential induced cytotoxicity is an important issue. The aim of this study was to investigate potential in vitro cytotoxic effects of different sorbent cartridges, HA130, HA230, HA330, HA380 (Jafron, China), on U937 monocytes.

Usefulness of glycated albumin as a biomarker for glucose control and prognostic factor in chronic kidney disease patients on dialysis (CKD-G5D).

In chronic kidney disease patients on dialysis (CKD-G5D) accurate assessment of glycemic control is vital to improve their outcome and survival. The best glycemic marker for glucose control in these patients is still debated because several clinical and pharmacological factors may affect the ability of the available biomarkers to reflect the patient's glycemic status properly. This review discusses the role of glycated albumin (GA) both as a biomarker for glucose control and as a prognostic factor in CKD-G5D; it also looks at the pros and cons of GA in comparison to the other markers and its usefulness in hemodialysis and peritoneal dialysis.

Preoperative Renal Functional Reserve Predicts Risk of Acute Kidney Injury After Cardiac Operation.

Background: Although acute kidney injury (AKI) frequently complicates cardiac operations, methods to determine AKI risk in patients without underlying kidney disease are lacking. Renal functional reserve (RFR) can be used to measure the capacity of the kidney to increase glomerular filtration rate under conditions of physiologic stress and may serve as a functional marker that assesses susceptibility to injury. We sought to determine whether preoperative RFR predicts postoperative AKI.

Predictors of rapid disease progression in autosomal dominant polycystic kidney disease.

Autosomal dominant polycystic kidney disease (ADPKD) is one of the most common genetic diseases with a reported prevalence of 1:400 to 1:1000. Since the intact kidneys can compensate for the loss of glomerular filtration in ADPKD patients, renal insufficiency usually remains undetected until almost the fourth decade of life. Hereafter, reliable diagnostic and prognostic biomarkers to identify ADPKD progression are urgently needed.
