Introduction: Heart failure (HF) is a significant global health issue associated with high morbidity and mortality. Accurate biomarkers are crucial for predicting adverse outcomes and informing management. High-sensitivity cardiac troponins T (hs-cTnT) and I (hs-cTnI) are important prognostic indicators in HF, though their predictive value can be affected by comorbidities, particularly renal dysfunction.

Objectives: This review evaluates the prognostic significance of troponin adjusted for renal function in patients with HF.

Methods: A comprehensive literature search was performed in PubMed, including studies from 2011 to September 2024, using specific MeSH terms related to HF, troponin, and prognosis.

Results: Thirty-two studies met the inclusion criteria, all indicating an association between troponin levels adjusted for renal function and cardiovascular mortality in HF patients (HR 1.67-3.22). High-sensitivity cardiac troponins T (hs-cTnT) and I (hs-cTnI) are independent predictors of cardiovascular mortality in acute heart failure (AHF). Increasing hs-cTnI levels, with a baseline threshold of 0.03 ng/mL, significantly correlate with mortality risk (P = .0011). Patients with hs-cTnT > 14 ng/L, > 21.5 ng/L, and > 26.5 ng/L exhibit increased all-cause mortality after adjusting for renal function. Despite these associations, the role of troponin in predicting heart failure readmissions remains inconsistent, indicating that elevated troponin levels do not reliably predict rehospitalization risk, particularly in those with advanced renal impairment.

Conclusions: High-sensitivity troponins (hs-cTnT and hs-cTnI) are independent predictors of mortality in heart failure, even after accounting for renal function, while their role in predicting hospitalizations is weaker.

Background: Non-steroidal anti-inflammatory drugs (NSAIDs) are common cause of acute kidney injury, but chronic kidney disease (CKD) risk of NSAIDs is controversial. Prior systematic reviews are outdated with some methodological flaws. We conducted this systematic review to clarify the association between chronic NSAIDs use and occurrence and/or progression of CKD.

Methods: MEDLINE, Cochrane Library, Web of Science and Science direct were searched for observational and interventional studies from inception to May 2023. Qualitative synthesis was performed. The meta-analysis used pooled odds ratios (OR) and hazard ratios (HR) to estimate the association between chronic NSAID use and CKD occurrence or progression.

Results: Forty studies with a total of 1757118 participants were included in the systematic review; of them 39 studies were suitable for meta-analysis. 56% of our included studies were recent, published within the last 10 years. The meta-analysis revealed a significant association between chronic NSAIDs use and CKD occurrence and progression. The pooled odds ratio was 1.24 (95% CI: 1.11-1.39, p <0.001, I² = 91.21%), and the pooled hazard ratio was 1.50 (95% CI: 1.31-1.7, p <0.001, I² = 90.77%). The pooled hazard ratio (HR) for individuals with no CKD at baseline was 1.31 (95% CI, 1.26-1.40), while for those with preexisting CKD, the HR was significantly higher at 1.67 (95% CI, 1.38-2.02). The HR for individuals with no specific chronic disease was 1.6 (95% CI, 1.32-1.94). For populations with diabetes mellitus (DM) and/or hypertension (HTN), the HR was 1.35 (95% CI, 1.27-1.43), and for those with rheumatic disease, the HR was 1.36 (95% CI, 0.88-2.10).

Conclusions: Long-term NSAID use increases the risk of chronic kidney disease (CKD) occurrence and progression, especially in individuals with pre-existing CKD, who have a 67% risk compared to the general population's 60%. A patient-centered approach for safe and effective pain management is crucial, with special caution for those with pre-existing CKD.

Introduction: The mortality rate of hemodialysis patients is extremely high and it is significantly affected by vascular access dysfunction. Our research aimed to determine predictive parameters of arteriovenous fistula functioning and survival in a one-year follow-up period.

Methods: The research was organized as a prospective, one-year study, which included 120 dialysis patients who were followed for one year. We recorded the demographic and gender structure, clinical parameters, and laboratory findings significant for the survival and functioning of arteriovenous fistulas. Laboratory findings are presented as the mean values of the analysis at the beginning and the end of the one-year control period.

Results: Univariable regression analysis confirmed the predictive significance of anastomosis positioning, type of vascular access, length of hemodialysis treatment, hemoglobin, Kt/V index values, and creatinine concentration for one-year survival, but multivariable regression analysis confirmed predictive significance only for length of treatment. Univariable regression analysis revealed significant predictors of vascular access function for the length of hemodialysis treatment, diastolic blood pressure, leukocytes, platelets, hemoglobin, creation of an arteriovenous fistula by a nephrologist, starting hemodialysis with a fistula and not with a central venous catheter, multivariable regression analysis confirmed predictive significance for the length of dialysis treatment and creation of an arteriovenous fistula by a nephrologist.

Conclusion: A prognostically important parameter for the one-year survival of a patient on hemodialysis is the length of dialysis treatment. In contrast, predictive parameters for the functioning of an arteriovenous fistula are the length of dialysis and the creation of a fistula by a nephrologist.

Background: Systemic sclerosis (SSc) is a complex connective tissue disease characterized by microangiopathy, immune dysregulation, and fibrosis. Early detection of microvascular abnormalities using nailfold videocapillaroscopy (NVC) is crucial in assessing disease progression and associated disease's involvement such as interstitial lung disease (ILD) and pulmonary arterial hypertension (PAH).

Objective: This study aims to explore the relationships correlation between NVC patterns, clinical manifestations, and systemic complications in SSc.

Methods: We analyzed the data of 63 patients, predominantly female (95%), with a mean age of 49 years and an average disease duration of 42 months. Patients were categorized into early, active, and late patterns based on NVC findings. Clinical features, including digital ulcers (DU), ILD, and PAH, were assessed. Pearson correlation analyses were performed to evaluate the relationships between capillary loss, neoangiogenesis, ILD, and PAH.

Results: The early pattern group (mean mRSS 2.36) exhibited minimal microvascular damage and systemic involvement, with no DUs. In the active pattern group (mean mRSS 10.40), 34.38% had diffuse cutaneous SSc (dcSSc), with 15.63% presenting DUs, 65.63% ILD, and 37.5% PAH. The late pattern group (mean mRSS 18.00) showed the most severe disease, with 80% having DUs, 70% dcSSc, 90% ILD, and 70% PAH. Pearson correlation analyses revealed strong correlations between capillary loss and ILD (r = 0.7255) and PAH (r = 0.6369). A moderate correlation was found between neoangiogenesis and PAH (r = 0.5592).

Conclusion: The study demonstrates that progressive microvascular damage in SSc, as visualized by NVC, correlates strongly with the severity of systemic complications. Early detection of capillary loss and neoangiogenesis using NVC is critical for timely interventions, which could improve patient outcomes by mitigating the progression of ILD and PAH.

Penicillin allergy is the most commonly reported drug allergy, with prevalence rates ranging from 6% to 31% across various populations and geographic areas. The penicillin allergy label is linked to higher mortality and morbidity rates, extended hospital stays, increased readmission rates, and a greater reliance on second-line antibiotics. Research indicates that nearly 99% of those labeled as penicillin-allergic can tolerate the drug. However, alternative antibiotics are often prescribed without confirming the allergy, largely due to legal concerns regarding re-exposure. Even when a negative challenge test is conducted, non-allergist providers may remain hesitant to reintroduce penicillins. To address the considerable gap between reported and actual penicillin allergies, as well as to ensure the prompt use of penicillins by non-allergists, various management strategies have emerged in recent years. Although several comprehensive reviews have examined these strategies, selecting and applying the most suitable for routine practice is difficult. This narrative review focuses on the most relevant data regarding the efficiency of key penicillin allergy risk-assessment tools, particularly those of clinical significance, and discusses their readiness for implementation in non-allergist settings.

Background: Given the importance of coronary artery disease (CAD) and the range of cardiovascular disease phenotypes in smokers, as well as the potential genetic and epigenetic factors, we were motivated to explore the impact of smoking on some selected microRNAs associated with significant CAD.

Methods: A total of 60 individuals were selected in four groups including non-smoker without significant CAD (S-A-), non-smokers with significant CAD (S-A+), smokers without significant CAD (S+A-) and smokers with significant CAD (S+A+). Micro-RNA expression was investigated using real-time PCR. General linear model was used to calculate fold change (FC) considering S-A- as the reference group.

Results: For mir-34a, down-regulation was observed in S+A- (FC =0.13, P =0.007) and S+A+ (FC =0.23, P =0.036) groups. For mir-126-3p, down-regulation was observed in S-A+ group (FC =0.05, P =0.024). For mir-199, up-regulation was observed for S+A- group (FC =9.38, P =0.007). The only significant interaction between pack-years of smoking and number of significantly narrowed vessels (≥75% stenosis) was for mir-199 which was in favor of down-regulation (P =0.006), while the main effects were in favor of up-regulation (P <0.05).

Conclusion: Mir-34a expression may be affected by smoking, whereas mir-126-3p expression may be affected by atherosclerosis, the most common reason of CAD. The significant down-regulation of mir-199 for the interaction of smoking dose and severity of CAD was a notable finding showing the harmful consequence of this interaction. Further studies are needed for this micro-RNA.

Introduction: The aim of the study was to assess the etiological distribution of patients with an erythrocyte sedimentation rate (ESR) over 100 mm/hour and to evaluate differences in demographic, comorbidity, laboratory characteristics, and clinical outcomes.

Methods: This retrospective observational clinical study included patients aged 18 years and older who were admitted to the internal medicine inpatient clinic between May 1, 2015 and June 1, 2021 and had ESR values above 100 mm/h. Demographic data, comorbidities, laboratory parameters, imaging studies, histopathological findings, microbiological and serological data, along with in-hospital and post-discharge mortality, were collected from the hospital's electronic database. Two independent clinicians evaluated the data to identify diagnoses associated with elevated ESR. Patients were divided into six categories based on the most likely diagnosis.

Results: The study included 441 patients, 52.6% of whom were female, and the mean age was 72.6 years. The etiological distribution was as follows: infectious diseases (34%), malignancies (31.5%), undiagnosed cases (15.9%), renal diseases (9.8%), other causes (5%), and rheumatologic diseases (3.8%). Etiological distributions did not differ by gender, age, or ESR ranges. The in-hospital mortality rate was 3.6%, and the overall mortality rate from hospitalization to the data collection date was 64.4%. Mortality was higher in patients with malignancies (81.3%) compared to other etiologies (p<0.001). Patients who died had higher mean age, ferritin levels, having diabetes mellitus, heart failure, or malignancy, and lower hemoglobin and lymphocyte levels compared to survivors (p<0.05 for all).

Conclusion: Most patients with an ESR over 100 mm/hour had significant underlying medical conditions, with infectious diseases and malignancies comprising two-thirds of the cases.

Purpose: To provide epidemiologic data on kidney biopsy from Romania.

Methods: Retrospective observational study of kidney biopsy records for adult patients from a referral center in the north-western part of Romania, reported for 2014-2023.

Results: 556 biopsies were performed, corresponding to an incidence of 12 biopsies/m person-year with over 50% increase over the last reported year. Optimal core for optic microscopy was available in 81.4%, immunofluorescence was performed in 86.3%, and electron microscopy in 35.2% of patients. The mean age at biopsy was 47.12 years, and 53.8% were males. Indications for kidney biopsy were nephrotic syndrome in 63.1% of patients, nephritic in 25.9% of patients, asymptomatic urinary abnormalities in 2.9%, acute kidney injury/ rapid progressive renal failure in 3.6%, and chronic kidney disease in 1.4%. The most frequent diagnostic categories were membranous nephritis (14.7%), IgA nephropathy (13.9%), focal segmental glomerulosclerosis (11,1%), minimal change disease (12,2%), lupus nephritis (10,9%), vasculitis (7.6%), and membranoproliferative glomerulonephritis (8%). The age of diagnosis increased for IgA Nephropathy over time while it decreased for membranous nephritis.

Conclusions: Our study adds data for the completion of the kidney biopsy map in our region.

Introduction: Infection with Epstein-Barr virus is a known risk factor for laryngeal carcinogenesis; it might influence DNA methylation acting as an epigenetic driver in this type of malignancy.

Methods: Paired laryngeal tissues (neoplastic and peri-neoplastic) harvested from 24 patients were included in the study. Eleven patients expressing latent/lytic EBV genes were considered positive. 5-mC% was determined using ELISA technique and TSGs (PDLIM4, WIF1, DAPK1) promoters' methylation percentages were quantified by qMS-PCR. DNMTs (DNMT1 and DNMT3B) expression levels were quantified in qRT-PCR.

Results: Overall, in laryngeal neoplastic samples vs peri-neoplastic ones, lower 5mC% (p=0.004) and higher TSGs promoters hypermethylation were found (p<0.0001). Significant correlation between PDLIM4 and DAPK1 promoter methylation and 5-mC% (PDLIM4 p=0.0186; DAPK1 p=0.0259) was noted. Higher 5-mC% (p=0.0041), lower PDLIM4 gene promoter methylation (p=0.0017) and overexpression of DNMTs (DNMT1: p=0.0018, respectively DNMT3B: p=0.0017) were associated with EBV infection. Also, significant differences between EBV-positive and EBV-negative cases based on tumor stage (T) were noted for 5mC% in both T1/T2 (p=0.0364) and T3/T4 stages (p=0.0275), and for PDLIM4 promoter methylation in T1/T2 stages (p=0.0121).

Conclusion: Future studies are needed to more effectively illustrate the interplay between EBV infection and these epigenetic mechanisms. Notably, our study highlighted a correlation between EBV and epigenetic changes in laryngeal carcinoma.

Introduction: Endocarditis is a pathology which is rarely encountered in clinical practice that presents itself in various manners, thus posing a great challenge for the clinician in the process of formulating a timely diagnosis, especially given its potentially lethal evolution. The diagnosis of infective endocarditis is based on Modified Duke Criteria. A wide array of complications may accompany endocarditis, including septic or thrombotic emboli to various territories - those occluding branches of cerebral arteries result in ischemic strokes, which may be demonstrated by brain imaging and the symptoms which may range from mild mental status alteration to deep coma. Objective: Assessment of brain imaging as a diagnostic tool for bacterial endocarditis.

Materials and methods: This is a nested case-control study, in which 84 patients with ischemic stroke were enrolled, half of them having endocarditis related stroke (cases), and the other half stroke due to cardioembolism from other sources or to large-artery atherosclerosis (controls).

Results: Brain imaging revealed statistically significant differences between the two cohorts, endocarditis related stroke being more strongly associated with multiple territories involvement, multiple lesions coexistence, watershed lesions, and a greater extent of ischemia all these may serve as valuable diagnostic clues. Among these findings, the presence of multiple lesions has been the most sensitive tool (Sn = 0.786, Sp = 0.857, LR+ = 5.497, LR- = 0.25), while the involvement of multiple arterial territories had the highest specificity and positive likelihood ratio for endocarditis-related stroke (Sn = 0.738, Sp = 0.929, LR+ = 10.394, LR- = 0.282). A larger ischemic lesion as quantified by pc-ASPECTS score (more than by the ASPECTS score) also increases the likelihood of endocarditis as the cause of ischemic stroke, with an AUROC of 0.7361 (95% CI 0.629-0.843).

Conclusions: Early brain imaging could play a crucial role in endocarditis, helping the clinician to suspect this diagnosis. Further studies are needed to understand the role of early brain imaging when Modified Duke Criteria fail to establish the diagnosis.
