Abnormalities of IL-12 Family Cytokine Pathways in Autosomal Dominant Polycystic Kidney Disease Progression.

Autosomal Dominant Polycystic Kidney Disease (ADPKD) is the most frequent genetic renal disease with a complex physiopathology. More and more studies sustain that inflammation plays a crucial role in ADPKD pathogenesis and progression. We evaluated IL-12 involvement in ADPKD pathophysiology by assessing the serum levels of its monomers and heterodimers.

Comparing Long-Term Outcomes in Glomerular Disease Patients Presenting with Nephrotic Syndrome Versus Nephrotic Range Proteinuria.

Background: Despite extensive research on proteinuria's impact on chronic kidney disease progression, there is no direct comparison of outcomes in biopsy-diagnosed glomerular disease (GD) patients with nephrotic syndrome (NS) or nephrotic range proteinuria (NRP). Our study addresses this gap, comparing long-term outcomes between NS and NRP.

Methods: We conducted a retrospective study on 240 kidney biopsy-proven GD patients, tracked from 2010 to 2015 until end-stage kidney disease (ESKD), death, or the study end in January 2022.

3D Bioprinting in Limb Salvage Surgery.

With the development of 3D bioprinting and the creation of innovative biocompatible materials, several new approaches have brought advantages to patients and surgical teams. Increasingly more bone defects are now treated using 3D-bioprinted prostheses and implementing new solutions relies on the ability of engineers and medical teams to identify methods of anchoring 3D-printed prostheses and to reveal the potential influence of bioactive materials on surrounding tissues. In this paper, we described why limb salvage surgery based on 3D bioprinting is a reliable and effective alternative to amputations, and why this approach is considered the new standard in modern medicine.

Are the Hematological Parameters Useful in Differentiating Acute Pyelonephritis from Cystitis in Patients with Chronic Kidney Disease?

Background And Objectives: The importance of hematological parameters has started to be explored with increased interest in many fields lately, with different studies finding an association between those parameters and inflammatory status, atherosclerosis, comorbidities, malnutrition, neoplasia and even a faster progression of chronic kidney disease (CKD). On the other hand, CKD itself presents as an inflammatory condition, in which a lot of pathways are modified and the response to an infectious agent could be less than expected. Regarding the latter aspect, in this study we aim to explore the differences between the hematologic response during a lower versus upper urinary tract infection in patients with CKD.

A Comprehensive Review of TRPS1 as a Diagnostic Immunohistochemical Marker for Primary Breast Carcinoma: Latest Insights and Diagnostic Pitfalls.

Background/objectives: Immunohistochemical expression of TRPS1 (trichorhinophalangeal syndrome type 1) protein is usually used by pathologists to confirm breast origin for triple-negative breast cancers (TNBC) or metastatic carcinomas of unknown primary. However, recent studies have reported TRPS1 expression in a variety of non-breast lesions. This review aims to provide a comprehensive evaluation of TRPS1 expression across various tumor types, highlighting both its diagnostic utility and potential pitfalls that may arise in clinical practice.

Low-Protein Diets Could Be Effective and Safe in Elderly Patients with Advanced Diabetic Kidney Disease.

Low-protein diets (LPDs) seem to improve metabolic complications of advanced CKD, thus postponing kidney replacement therapy (KRT) initiation. However, the nutritional safety of LPDs remains debatable in patients with diabetic kidney disease (DKD), especially in the elderly. This is a sub-analysis of a prospective unicentric interventional study which assessed the effects of LPD in patients with advanced DKD, focusing on the feasibility and safety of LPD in elderly patients.

Clinicopathological Characteristics and Disease Chronicity in Glomerular Diseases: A Decade-Long Study at Romania's Largest Kidney Biopsy Reference Center.

Glomerular diseases (GDs), significant causes of end-stage kidney disease, are better understood through epidemiological studies based on kidney biopsies (KBs), which provide important insights into their prevalence and characteristics. This study aims to analyze the clinicopathological features of GDs diagnosed from 2008 to 2017 at Romania's largest reference center. In this decade-long study, 1254 adult patients diagnosed with GDs were included.

Low Protein Diet Reduces Proteinuria and Decline in Glomerular Filtration Rate in Advanced, Heavy Proteinuric Diabetic Kidney Disease.

Low protein diet (LPD) seems beneficial in ameliorating the complications of chronic kidney disease (CKD), in reducing proteinuria and the decline in kidney function, thus postponing the need for kidney replacement therapy (KRT). However, this type of intervention was less investigated in diabetic kidney disease (DKD). This is a single-center, prospective, interventional study that aims to assess the efficacy of reducing proteinuria and the rate of decline in the estimated glomerular filtration rate (eGFR).

Pathological and Molecular Diagnosis of Uveal Melanoma.

(1) Background: Uveal melanoma (UM) is a common malignant intraocular tumor that presents with significant genetic differences to cutaneous melanoma and has a high genetic burden in terms of prognosis. (2) Methods: A systematic literature search of several repositories on uveal melanoma diagnosis, prognosis, molecular analysis, and treatment was conducted. (3) Results: Recent genetic understanding of oncogene-initiation mutations in GNAQ, GNA11, PLCB4, and CYSLTR2 and secondary progression drivers of BAP1 inactivation and SF3B1 and EIF1AX mutations offers an appealing explanation to the high prognostic impact of adding genetic profiling to clinical UM classification.

Septic acute kidney injury and gut microbiome: Should we change our approach?

Incidence of acute kidney injury (AKI) remained relatively stable over the last decade and the adjusted risks for it and mortality are similar across different continents and regions. Also, the mortality of septic-AKI can reach 70% in critically-ill patients. These sole facts can give rise to a question: is there something we do not understand yet? Currently, there are no specific therapies for septic AKI and the treatment aims only to maintain the mean arterial pressure over 65mmHg by ensuring a good fluid resuscitation and by using vasopressors, along with antibiotics.

The Role of the L-Arginine-Nitric Oxide Molecular Pathway in Autosomal Dominant Polycystic Kidney Disease.

Recently, arginine has been proven to play an important role in ADPKD physiopathology. Arginine auxotrophy in ADPKD induces cell hyperproliferation, blocking the normal differentiation of renal tube cells and causing cyst formation. We explored the L-arginine (Arg)-nitric oxide (NO) molecular pathway in ADPKD, a multisystemic arginine auxotrophe disease.

Mortality in IgA Nephropathy: A Long-Term Follow-Up of an Eastern European Cohort.

: IgA nephropathy (IgAN), the most common primary glomerulonephritis, has been extensively studied for renal outcomes, with limited data on patient survival, particularly in Eastern Europe. We aimed to investigate the long-term survival rate of patients with IgAN and the associated risk factors in an Eastern European cohort. : We conducted a retrospective analysis of 215 IgAN patients (median age 44, 71% male) diagnosed at a Romanian tertiary center between 2010 and 2017.

Prognostic role of mesangial IgM deposition in IgA nephropathy: a long-term cohort study.

Background: The clinical significance of mesangial immunoglobulin (Ig) M deposition in IgA nephropathy (IgAN) has been less explored and remains a topic of debate. Therefore, our study aimed to investigate the prognostic value of mesangial IgM deposition in a long-term follow-up cohort of IgAN patients.

Methods: A unicentric retrospective study was conducted on 93 consecutive IgAN patients (median age 41 years, 68% male, eGFR 48.

Centricity on patients using healthcare reputation management strategies to improve dentistry image in Romania.

Reputation is seen as an abstract concept that focuses on patients' perceptions of a particular medical institution. A good image of these practices among patients makes them return to them and also helps attract new patients and increase their reputation and revenue. The paper aimed to explore the respondents' perceptions of the way the image of online dental practices can influence their reputation management.

Disturbances in Nitric Oxide Cycle and Related Molecular Pathways in Clear Cell Renal Cell Carcinoma.

It is important to note that maintaining adequate levels of nitric oxide (NO), the turnover, and the oxidation level of nitrogen are essential for the optimal progression of cellular processes, and alterations in the NO cycle indicate a crucial step in the onset and progression of multiple diseases. Cellular accumulation of NO and reactive nitrogen species in many types of tumour cells is expressed by an increased susceptibility to oxidative stress in the tumour microenvironment. Clear cell renal cell carcinoma (ccRCC) is a progressive metabolic disease in which tumour cells can adapt to metabolic reprogramming to enhance NO production in the tumour space.

The Impact of Infections on the Progression of Chronic Kidney Disease.

: Infectious diseases continue to be a global burden and their impact is even worse if the patients already have other comorbidities. Because chronic kidney disease is very frequent, affecting 10% of the population, our study aims to explore the impact that infectious events have on its progression. : This is a retrospective, observational study based on a cohort of 238 dialyzed patients from the Nephrology Clinic of "Dr.

Lupus nephritis with cryoglobulinemic glomerulonephritis features: a diagnostic conundrum.

In this clinical case, we report an atypical and unique presentation of systemic lupus erythematosus (SLE) in a 39-year-old female with nephrotic syndrome. The patient exhibited class IV plus V lupus nephritis and extensive immune complex deposition within the intracapillary and arteriolar regions suggestive of cryoglobulinemic glomerulonephritis, despite no detectable circulating cryoglobulins. Electron microscopy revealed cryoglobulin-like deposit distribution in all glomerular examined compartments, namely subendothelial, intramembranous, subepithelial, and mesangial, apparently extending from the capillary hyaline thrombi.

Angiogenic systemic response to the hypoxic microenvironment in prostate tumorigenesis: A pilot study.

The present paper aimed to investigate the altered angiogenetic mechanisms in hypoxic conditions in patients with prostate tumours, in correlation with common clinicopathologic variables. A case-control study was developed and included 87 patients with prostate tumours [40 diagnosed with benign prostatic hyperplasia (BPH) and 47 diagnosed with prostate cancer (PCa), using prostate transrectal biopsy] and 40 healthy subjects. The following parameters were evaluated in the serum of volunteers: Hypoxia-inducible factor (HIF)-1α, fibroblast growth factor (FGF)-2, vascular endothelial growth factor (VEGF), matrix metalloproteinase (MMP)-2 and -9, thrombospondin (TSP)-1 and soluble VEGF-1 receptor.

A closer look: ultrastructural evaluation of high-risk progression IgA nephropathy.

This retrospective, cross-sectional study sought to examine the ultrastructural characteristics of glomerular lesions using Transmission Electron Microscopy (TEM) in IgA nephropathy (IgAN) and their relationship with the high risk of progression phenotype defined by KDIGO guideline as proteinuria ≥1 g/24 hours despite 3 months of optimized supportive care. We analyzed 81 IgAN patients (median age 41 years, 67% male, eGFR 43.8 mL/min, proteinuria 1.

Prognostic role of glomerular electron microscopy lesions in IgA nephropathy: "the devil is in the details".

Introduction: Transmission electron microscopy enables examination of ultrastructural glomerular changes; while this tool has already been applied in IgA nephropathy (IgAN), limited information exists on the prognostic value in this disease. We aimed to systematically investigate ultrastructural lesions and assess their role in predicting the evolution of IgA nephropathy to end-stage kidney disease.

Methods: A single-center retrospective study was performed on 107 consecutive IgAN patients (median age 42 years, 67% male, estimated glomerular filtration rate 46 mL/min, proteinuria 1.

The Microbiome and Protein Carbamylation: Potential Targets for Protein-Restricted Diets Supplemented with Ketoanalogues in Predialysis Chronic Kidney Disease.

In chronic kidney disease (CKD), metabolic derangements resulting from the interplay between decreasing renal excretory capacity and impaired gut function contribute to accelerating disease progression and enhancing the risk of complications. To protect residual kidney function and improve quality of life in conservatively managed predialysis CKD patients, current guidelines recommend protein-restricted diets supplemented with essential amino acids (EAAs) and their ketoanalogues (KAs). In clinical studies, such an approach improved nitrogen balance and other secondary metabolic disturbances, translating to clinical benefits, mainly the delayed initiation of dialysis.
