Renal involvement in sarcoidosis: histological patterns and prognosis, an Italian survey.

Background: Granulomatous interstitial nephritis in sarcoidosis (sGIN) is generally clinically silent, but in <1% causes acute kidney injury (AKI).

Methods: This Italian multicentric retrospective study included 39 sarcoidosis-patients with renal involvement at renal biopsy: 31 sGIN-AKI, 5 with other patterns (No-sGIN-AKI), 3 with nephrotic proteinuria. We investigate the predictive value of clinical features, laboratory, radiological parameters and histological patterns regarding steroid response.

The genetic architecture of membranous nephropathy and its potential to improve non-invasive diagnosis.

Membranous Nephropathy (MN) is a rare autoimmune cause of kidney failure. Here we report a genome-wide association study (GWAS) for primary MN in 3,782 cases and 9,038 controls of East Asian and European ancestries. We discover two previously unreported loci, NFKB1 (rs230540, OR = 1.

Contraception in chronic kidney disease: a best practice position statement by the Kidney and Pregnancy Group of the Italian Society of Nephrology.

Even though fertility is reduced, conception and delivery are possible in all stages of CKD. While successful planned pregnancies are increasing, an unwanted pregnancy may have long-lasting deleterious effects, hence the importance of birth control, an issue often disregarded in clinical practice. The evidence summarized in this position statement is mainly derived from the overall population, or other patient categories, in the lack of guidelines specifically addressed to CKD.

[Psychological Assessment of a sample of women with ADPKD: quality of life, body image, anxiety and depression].

Introduction: The Autosomal Dominant Polycystic Kidney Disease (ADPKD) is a chronic renal disease that has not yet been the subject of psychological research. There are only a few studies related to the consequences and complications of this pathology on female patients, although women affected by this disease present serious problems.

Aim: The purpose of this study is to perform a psychological assessment (quality of life, anxiety, depression, body image) on a sample of 37 women with ADPKD.

Pregnancy in women with diabetic nephropathy.

The number of pregnancies in women with pregestational diabetes has been steadily increasing worldwide. These pregnancies are associated with an increased risk of a variety of complications, including miscarriages, congenital malformations, macrosomia, fetal growth restriction, preeclampsia, preterm delivery and stillbirth. In pregnant women with diabetic nephropathy it is important to evaluate both the effect of pregnancy on kidney function and the effect of kidney disease on pregnancy outcomes.

Claudin-14 Gene Polymorphisms and Urine Calcium Excretion.

Background And Objectives: Claudin-16 and -19 are proteins forming pores for the paracellular reabsorption of divalent cations in the ascending limb of Henle loop; conversely, claudin-14 decreases ion permeability of these pores. Single-nucleotide polymorphisms in gene coding for were associated with kidney stones and calcium excretion. This study aimed to explore the association of , , and single-nucleotide polymorphisms with calcium excretion.

A best-practice position statement on pregnancy after kidney transplantation: focusing on the unsolved questions. The Kidney and Pregnancy Study Group of the Italian Society of Nephrology.

Kidney transplantation (KT) is often considered to be the method best able to restore fertility in a woman with chronic kidney disease (CKD). However, pregnancies in KT are not devoid of risks (in particular prematurity, small for gestational age babies, and the hypertensive disorders of pregnancy). An ideal profile of the potential KT mother includes "normal" or "good" kidney function (usually defined as glomerular filtration rate, GFR ≥ 60 ml/min), scant or no proteinuria (usually defined as below 500 mg/dl), normal or well controlled blood pressure (one drug only and no sign of end-organ damage), no recent acute rejection, good compliance and low-dose immunosuppression, without the use of potentially teratogen drugs (mycophenolic acid and m-Tor inhibitors) and an interval of at least 1-2 years after transplantation.

Moral Distress (MD) and burnout in mental health nurses: a multicenter survey.

Introduction: Moral Distress (MD) is a common experience among nurses and if it is not recognised and treated, it may lead to serious consequences on nurses' health and quality of care. MD has been studied in several healthcare contexts. However, there are only few studies on MD in psychiatry and in Italy there are no data in this field.

[Clinical practice for the diagnosis of cardiac arrhythmias in patients on renal replacement therapy: data from a Lombard survey].

Among dialysis patients, 40% of deaths are due to cardiovascular causes, and 60% of cardiac deaths are due to an arrhythmia. The purpose of this survey, carried out with the organizational support of the Lombard Section of the Italian Society of Nephrology, is to evaluate the frequency and mode of use of non-invasive instruments for the diagnosis of cardiac arrhythmias in the dialysis centers of Lombardy. Information on the prevalence and type of cardiac devices at December 1, 2016 in this population was also required.

[Students, clinical nurse preceptors and academic tutors' perception and experience in relation to the implementation of a Dedicated Education Unit: a qualitative study using focus group.].

Objective: analyse students, clinical nurse preceptors and academic tutors' perception and experience further to the implementation of a Dedicated Education Unit (DEU) in a pulmonary medicine ward.

Method: The study follows a qualitative descriptive method. Data have been collected through focus groups (FGs).

A best practice position statement on the role of the nephrologist in the prevention and follow-up of preeclampsia: the Italian study group on kidney and pregnancy.

Preeclampsia (PE) is a protean syndrome causing a transitory kidney disease, characterised by hypertension and proteinuria, ultimately reversible after delivery. Its prevalence is variously estimated, from 3 to 5% to 10% if all the related disorders, including also pregnancy-induced hypertension (PIH) and HELLP syndrome (haemolysis, increase in liver enzyme, low platelets) are included. Both nephrologists and obstetricians are involved in the management of the disease, according to different protocols, and the clinical management, as well as the role for each specialty, differs worldwide.

[Translation and validation in italian of the Moral Distress Scale for psychiatric nurses (MDS-P)].

Aim: Moral distress (MD) is a painful feeling and/or psychological disequilibrium, which may lead to negative consequences into the wellness of a nurse's working life. Nurses who work in psychiatry are more likely to experience a different type of MD compared with nurses of other contexts. In Italy a tool to evaluate MD in nurses who work in psychiatry doesn't exist.

Intestinal Calcium Absorption among Hypercalciuric Patients with or without Calcium Kidney Stones.

Background And Objectives: Idiopathic hypercalciuria is a frequent defect in calcium kidney stone formers that is associated with high intestinal calcium absorption and osteopenia. Characteristics distinguishing hypercalciuric stone formers from hypercalciuric patients without kidney stone history (HNSFs) are unknown and were explored in our study.

Design, Setting, Participants, & Measurements: We compared 172 hypercalciuric stone formers with 36 HNSFs retrospectively selected from patients referred to outpatient clinics of the San Raffaele Hospital in Milan from 1998 to 2003.

Impact of European medicines agency recommendations for hypersensitivity reactions on intravenous iron prescription in haemodialysis centres of the Lombardy region.

Background: The European Medicines Agency (EMA) has recommended measures to minimize the risk of hypersensitivity reactions (HSRs) to intravenous iron (IVFe). We analysed the effects of these recommendations on IVFe clinical management among haemodialysis centres (HDCs) in Lombardy, Italy.

Materials And Methods: A questionnaire was sent to all 117 HDCs to collect information on centre characteristics, e.

[Burnout in healthcare professionals: a study carried out in the Nephrology Unit of San Raffaele Hospital].

Burnout is a work stress syndrome caused by a prolonged contact with users which present physical and emotional suffering. C. Maslach, one of the main authors, refers that this syndrome is characterized by emotional exhaustion, depersonalization and reduced personal skills.

Generation of Donor-specific T Regulatory Type 1 Cells From Patients on Dialysis for Cell Therapy After Kidney Transplantation.

Background: T regulatory type 1 (Tr1) cell-mediated induction of tolerance in preclinical models of transplantation is remarkably effective. The clinical application of such a therapy in patients on dialysis undergoing kidney transplantation should take into account the possible alterations of the immune system observed in these patients. Herein, we aimed at testing the ability to generate donor-specific Tr1 cell-enriched lymphocytes from patients on dialysis on the waiting list for kidney transplantation.

Dietary style and acid load in an Italian population of calcium kidney stone formers.

Background And Aims: Animal protein intake may cause an acid load that predisposes individuals to stones by influencing calcium and citrate excretion. These associations were not confirmed in recent studies. Therefore the present study was aimed to compare acid load of diet in stone formers and controls.

Nonpharmacological techniques to reduce pain in preterm infants who receive heel-lance procedure: a randomized controlled trial.

Introduction: The heel-lance (HL) method for blood collection from the newborn is controversial for the pain it causes. This is the first randomized controlled trial on the management and reduction of pain using the music of Wolfgang Amadeus Mozart ("Sonata K. 448") in premature infants hospitalized in a neonatal intensive care unit (NICU).

[Integration of a psychologist into Nephrology-Dialysis-Hypertension Operative Unit: from needs evaluation to the definition of an intervention model].

Chronic Kidney Disease (CKD) and the dialytic treatment cause a significant psychological impact on patients, their families and on the medical-nursing staff too. The psychological aspects linked to the chronic condition of Kidney Disease generate the need to integrated a psychologist into the healthcare team of the Nephrology, Dialysis and Hypertension Operative Unit, in order to offer a specific and professional support to the patient during the different stages of the disease, to their caregivers and to the medical team. The aim of this collaboration project between Nephrology and Psychology is to create a global and integrated healthcare model.

Risk of nephrolithiasis in primary hyperparathyroidism is associated with two polymorphisms of the calcium-sensing receptor gene.

Aims: Two single-nucleotide polymorphisms (SNPs) at the calcium-sensing receptor (CASR) gene were previously associated with kidney stones in patients with primary hyperparathyroidism (PHPT): rs1501899, likely associated with a decrease in CASR expression, and Arg990Gly, causing a gain of CASR function. To evaluate the interaction of these two SNPs in the stone risk, we tested the association of stones with the genotype at both SNPs in PHPT patients and the association of rs1501899 with CASR expression as messenger RNA (mRNA) in human kidney samples.

Methods And Results: Two hundred and ninety-six PHPT patients were genotyped at the rs1501899 and Arg990Gly SNPs.

Decreased transcriptional activity of calcium-sensing receptor gene promoter 1 is associated with calcium nephrolithiasis.

Background: CaSR gene is a candidate for calcium nephrolithiasis. Single-nucleotide polymorphisms (SNPs) encompassing its regulatory region were associated with calcium nephrolithiasis.

Aims: We tested SNPs in the CaSR gene regulatory region associated with calcium nephrolithiasis and their effects in kidney.

Calcium sensing receptor and renal mineral ion transport.

Calcium sensing receptor (CaSR) is a component of the C family of the G protein-coupled receptors. It is ubiquitously expressed in human and mammal cells but is more expressed in parathyroid glands and kidney cells. It is located on the cell plasma membrane and senses the changes of extracellular calcium concentrations.
