Background/Objectives: Erysipelas is an acute bacterial skin infection, particularly affecting the lower limbs, with a tendency to recur. Despite its clinical importance, data on demographic and epidemiological risk factors, as well as factors influencing hospitalization, remain limited. This study aimed to analyze the epidemiological and clinical characteristics of patients hospitalized with primary and recurrent erysipelas, focusing on risk factors contributing to disease onset, recurrence, and prolonged hospitalization. Methods: A retrospective single-center analysis was conducted on 239 patients hospitalized for erysipelas at the Department of Dermatology, Pediatric Dermatology, and Oncology at the Medical University of Lodz. Data collected included demographics, lesion location, laboratory markers, comorbidities, and hospitalization outcomes. Statistical analyses were performed to assess associations between risk factors, disease recurrence, and hospitalization duration. Results: The majority of erysipelas cases (85.4%) involved the lower limbs, with a higher prevalence in men. Upper extremities were mostly affected in women, especially those who had undergone breast cancer surgery. Recurrent erysipelas accounted for 75.7% of cases. Most patients (89.1%) had at least one comorbidity, with hypertension, diabetes type 2 (DM2), and obesity being the most common. Higher white blood cell (WBC) count, obesity, atrial fibrillation (AF), and the need for enoxaparin administration were independently associated with prolonged hospitalization. Dyslipidemia was significantly associated with erysipelas recurrence (p < 0.05). Conclusions: Both primary and recurrent erysipelas are associated with specific risk factors. Recurrent erysipelas may be linked to components of metabolic syndrome, particularly obesity and dyslipidemia, which emerged as a significant risk factor in this study. Hospitalization length may be prolonged by inflammation markers (WBC and CRP) and comorbidities such as AF, obesity, or the need for enoxaparin in patients with elevated thrombosis risk. Further multicenter studies with larger cohorts are needed to assess the impact of demographics, biomarkers, metabolic disorders, and treatment strategies on erysipelas recurrence and outcomes. Awareness of these risk factors is essential for effective prevention, management, and recurrence reduction. Full article

Background/Objectives: Glucocorticoids (GCs) are frequently prescribed to control disease in Rheumatoid Arthritis (RA). However, long-term GC therapy with high daily doses is associated with bone involvement, which is considered the main extra-articular complication of RA. The trabecular bone score (TBS) has proven useful in assessing vertebral trabecular bone quality and fracture risk. To identify whether the long-term treatment of low doses of GCs are associated with low vertebral TBS in RA patients. Methods: A cross-sectional study, including 203 women with RA (ACR, 1987). Clinical, epidemiologic, and therapeutic variables were assessed. We identified the current daily dose, duration, and cumulative dose of GCs. Vertebral bone quality was assessed by TBS. Low vertebral trabecular bone quality was defined as TBS ≤ 1.300. Multivariate logistic regression analyses were used to identify risk factors of low TBS. Results: Prevalence of low TBS in RA women was 52%. RA + low TBS were older (61.9 vs. 55.5, p < 0.001) and had higher prevalence of menopause (90% vs. 75%, p = 0.004), hypertension (50% vs. 34%, p ≤ 0.02), and diabetes mellitus (13% vs. 4%, p = 0.02). There were no associations between GC use, neither doses or cumulative doses, and TBS. Multivariate analyses showed the following: age (OR: 1.05, 95% CI: 1.02–1.08) and the presence of diabetes mellitus (OR: 3.30, 95% CI: 1.03–10.60) were associated with a high risk of low vertebral trabecular bone quality in RA. Conclusions: Half of the RA patients had low trabecular bone quality. Older age and diabetes mellitus are important risk factors for low trabecular bone quality in RA. These findings should give alert to early detection of low TBS, establishing strategies aimed at avoiding the consequences of this complication, including vertebral fractures. Full article

Chronic thromboembolic pulmonary hypertension (CTEPH) is a rare, progressive form of pre-capillary pulmonary hypertension characterized by persistent, organized thromboemboli in the pulmonary vasculature, leading to vascular remodeling, elevated pulmonary artery pressures, right heart failure, and significant morbidity and mortality if untreated. Despite advances, CTEPH remains underdiagnosed due to nonspecific symptoms and overlapping features with other forms of pulmonary hypertension. Basic Methodology: This review synthesizes data from large international registries, epidemiologic studies, translational research, and multicenter clinical trials. Key methodologies include analysis of registry data to assess incidence and risk factors, histopathological examination of lung specimens, and molecular studies investigating endothelial dysfunction and inflammatory pathways. Diagnostic modalities and treatment outcomes are evaluated through observational studies and randomized controlled trials. Recent Advances and Affected Population: Research has elucidated that CTEPH arises from incomplete resolution of pulmonary emboli, with subsequent fibrotic transformation mediated by dysregulated TGF-β/TGFBI signaling, endothelial dysfunction, and chronic inflammation. Affected populations are typically older adults, often with prior venous thromboembolism, splenectomy, or prothrombotic conditions, though up to 25% have no history of acute PE. The disease burden is substantial, with delayed diagnosis contributing to worse outcomes and higher societal costs. Microvascular arteriopathy and PAH-like lesions in non-occluded vessels further complicate the clinical picture. Conclusions: CTEPH is now recognized as a treatable disease, with multimodal therapies—surgical endarterectomy, balloon pulmonary angioplasty, and targeted pharmacotherapy—significantly improving survival and quality of life. Ongoing research into molecular mechanisms and biomarker-driven diagnostics promises earlier identification and more personalized management. Multidisciplinary care and continued translational investigation are essential to further reduce mortality and optimize outcomes for this complex patient population. Full article

Background and purpose: Indigenous people in the Brazilian Amazon are exposed to mercury by eating methylmercury-contaminated fish. The lack of information on the health effects of prolonged exposure to mercury hinders the implementation of mitigation programs offered by the Brazilian government. This article aims to evaluate the studies that have investigated mercury exposure in indigenous people living in the Brazilian Amazon. Methods: A scoping review of the literature was conducted from studies published between 1995 and 2024 in Portuguese, English, and Spanish that evaluated mercury (Hg) concentrations in hair samples in indigenous people from the Brazilian Amazon. Results: Using total mercury (TotalHg) values in hair samples, we analyzed exposure levels, prevalence, and toxic effects. We found 15 epidemiological studies with a cross-sectional design and sample sizes ranging from 31 to 910 participants. Four studies involved children and mothers, four of which were associated with clinical outcomes and three of which analyzed genetic polymorphism. Most of the communities evaluated had a high prevalence of mercury exposure, showing levels ranging from 0.8 to 83.89 µg/g, and the highest average TotalHg concentration was found among the Kayabi. Mercury was associated with hypertension, cognitive disorders, worse mental health indicators and central and peripheral neurological disorders. Conclusions: It is concluded that indigenous people in the Brazilian Amazon experience exposure levels that are causing damage to their health, and control measures must be adopted to prevent the situation from worsening.

Heart failure (HF) is a complex clinical syndrome that results from any structural or functional impairment of ventricular filling or ejection of blood. The etiology of heart failure is multifactorial, encompassing ischemic heart disease, hypertension, valvular disorders, cardiomyopathies, and metabolic and infiltrative diseases. Despite advances in pharmacologic and device-based therapies, heart failure continues to carry a substantial burden of morbidity, mortality, and healthcare utilization. With the advancement and increased accessibility of cardiac imaging modalities, the diagnostic accuracy for identifying the underlying etiologies of nonischemic cardiomyopathy has significantly improved, allowing for more precise classification and tailored management strategies. This review aims to provide a comprehensive analysis of the current understanding of heart failure, encompassing epidemiology, etiological factors, with a specific focus on diagnostic imaging modalities including the role of echocardiography and strain imaging, cardiac magnetic resonance imaging (CMR), cardiac computed tomography (CT), and nuclear positron emission tomography (PET) imaging and recent advances in the diagnosis and management of heart failure.

Liver cirrhosis poses major challenges for both individual health and global healthcare systems. Recent studies have challenged the traditional and predictable linear course of cirrhosis, demonstrating marked heterogeneity in the patterns of the first decompensating events. This review presents an updated epidemiology of cirrhosis and its main causes, outlines an overview of the clinical features, and explores the evolving concepts of the spectrum of decompensation. It further delineates recent advancements in the diagnosis, prognostic scoring, and management of decompensated cirrhosis and the subsequent clinically challenging complications of portal hypertension. Emerging innovations in non-invasive imaging, diagnostic serum biomarkers, and etiology-specific therapies, together with the development of novel liver support systems, underscore a paradigm shift toward a multimodal approach for cirrhosis care. Furthermore, the integration of precision medicine into clinical practice holds promise for reshaping the future of liver cirrhosis management in the coming decades. Full article

Uncomplicated hypertension (UH) during pregnancy represents a common condition, worsening maternal and fetal prognosis. However, no single biomarker has proven optimal for determining the risk of UH. We developed an early risk multivariate model for UH, integrating hemodynamics with biochemistry, focusing on the relationship between blood pressure (BP) indices, uric acid (UA), and angiogenesis-related factors (AF). We collected and analyzed data on 24 h ambulatory BP monitoring, demographic, epidemiological, clinical, and laboratory variables from 132 pregnancies. The main predictors were BP indices and serum UA and AF levels. Uncomplicated hypertension, defined as the presence of gestational hypertension or worsening of essential hypertension beyond the 20th week, was the main outcome. The combined second-degree polynomial transformation of UA and the AF (sFlt-1/PIGF) ratio, called the UA-AF Index, consistently showed a positive association with UH. The models incorporating nighttime BP indices combined with the UA-AF Index outperformed the others, with the best-performing model based on the nocturnal systolic BP (SBP). Specifically, in the best-fitting model (nighttime SBP + UA-AF Index as predictors), each 1 mmHg increase in nocturnal SBP was associated with a 10% higher risk of UH, while each one-unit increase in the UA-AF Index raised the likelihood of UH by more than twofold (accuracy: 0.830, AUC 0. 874, SE 0.032, p-value < 0.001, 95%CI 0.811–0.938). The combination of nighttime blood pressure indices, serum uric acid, and angiogenesis-related factors may provide added value in the assessment of uncomplicated hypertension during pregnancy.

Background/Objectives: Patients with gastric cancer (GC) have an elevated risk of atrial fibrillation (AF) and cardiovascular mortality, compared with the general population. However, the effect of the cancer stage on the development of AF remains unclear. This study aimed to evaluate the relationship between the risk of AF and GC stage based on the Surveillance, Epidemiology, and End Results (SEER) stage classifications. Methods: This retrospective population-based cohort study enrolled patients diagnosed with GC between 2012 and 2019, using anonymized data from the Cancer Public Library Database of South Korea. Patients were followed up until 2020. The risk of AF was assessed in relation to the SEER stage of GC (localized, regional, distant) using adjusted hazard ratios (aHRs) with 95% confidence intervals (CIs). Subgroup analyses were performed according to age, sex, year of diagnosis, and comorbidities. Results: Of the 211,500 patients enrolled in this study, 7266 were diagnosed with AF during follow-up. The risk of AF increased progressively with cancer stage, with aHRs of 2.00 (95% CI 1.81–2.22) for the distant stage and 1.32 (95% 1.25–1.41) for the regional stage, compared with the localized stage. Subgroup analyses showed a consistent association between advanced cancer stage and a higher AF risk; the association was stronger in the younger, female, and non-hypertensive subgroups. Conclusions: The risk of AF in patients with GC is associated with the initial stage, highlighting the need for the closer monitoring and management of AF to improve the survival of patients with advanced-stage GC.

This study aimed to examine global hypertensive heart disease (HHD) trends (1990–2019). Methods: We extracted data from the Global Burden of Disease (GBD) 2019 Study, encompassing 204 countries and territories. We analyzed the age-adjusted mortality rates (AAMRs), crude mortality, prevalence, years lived with disability (YLD), years of life lost (YLL), and disability-adjusted life years (DALY). Joinpoint Regression Analysis was used to calculate the Annual Percentage Change (APC), with p < 0.05 indicating statistical significance. Results were stratified by region, Socio-Demographic Index (SDI), and gender. Results: Globally, the crude mortality rate for HHD rose from 12.2 (95% UI 9.9–13.6) to 14.9 (95% UI 16.5–11.1) deaths/100,000 population (1990–2019), whereas the AAMR declined from 19.3 (95% UI 5.8–21.6) to 15.1 (95% UI 11.1–16.7). A Joinpoint Analysis revealed significant APC shifts: a decrease of −1.53% (p < 0.05) from 1990 to 2006, an increase of +0.60% (p < 0.05) from 2006 to 2015, and a subsequent decrease of −1.28% (p < 0.05) from 2006 to 2019. Eastern Europe showed the highest annual rate of change in AAMR at 0.9 (95% UI: −0.1 to 1.2), whereas the high-income Asia Pacific region experienced the largest decline at −0.66 (95% UI −0.27–−0.72). Central Asian males had an AAMR of 31.1 (95% UI 35.3–22.9) in 2019, and Sub-Saharan African females reached 38.5 (95% UI 48.4–26.3). YLL trended downward in both sexes (APC: −1.94, p < 0.05 in males; −1.81, p < 0.05 in females), yet YLD rose steadily in recent years, underscoring a growing chronic burden. The AAMR was highest in 2019 among Sub-Saharan African females, which is a particularly important area. Conclusions: Targeted strategies are essential to mitigate the escalating HHD burden.

Insulin resistance is a condition wherein cells fail to adequately respond to insulin. It is a prevalent medical condition associated with several diseases, such as type 2 diabetes mellitus, metabolic syndrome, hypertension, obesity, and polycystic ovary syndrome. Insulin resistance may be involved in metabolic disturbances, such as hyperglycemia, hyperinsulinemia, dyslipidemia, hyperuricemia, endothelial dysfunction, elevated inflammatory markers, and a prothrombotic state. Severe insulin resistance syndromes are a heterogeneous group of rare disorders. These disorders are characterized by profound insulin resistance, substantial metabolic abnormalities, and different clinical manifestations and complications. They may be hereditary or acquired, caused by defects in insulin action and cellular responsiveness to insulin. Severe insulin resistance syndromes may also be due to aberrations in adipose tissue function and development. The majority of these disorders are associated with an increased risk of severe complications and mortality. This review aims to summarize the current knowledge on the epidemiology, pathophysiology, complications and prognosis of severe insulin resistance syndromes, as well as to categorize these syndromes by disease process, including defects in insulin receptor, intracellular insulin signaling defects, lipodystrophies, etc. Full article

Background/Objectives: Although ectopic pregnancy has been extensively studied in terms of epidemiology, associated risk factors, diagnostic approaches, and treatment modalities, the data regarding its impact on the development of adverse outcomes in subsequent pregnancy remain scarce and conflicting. We aim to evaluate the adverse perinatal outcomes of women with a history of ectopic pregnancy Methods: We used the Medline (1966–2024), Scopus (2004–2024), Clinicaltrials.gov (2008–2024), EMBASE (1980–2024), Cochrane Central Register of Controlled Trials CENTRAL (1999–2024), and Google Scholar (2004–2024) databases in our primary search. All studies that evaluated the impact of prior of ectopic pregnancy on the perinatal outcomes of the subsequent pregnancy and reported rates of adverse perinatal outcomes were considered eligible for inclusion. Twelve peer-reviewed papers were considered for inclusion in our study. We enrolled a total of 2,162,731 women. Of those, 23,823 (1.1%) had a history of prior ectopic pregnancy. A total of 4 out of 12 studies provided the necessary data to be included in the metanalysis. Results: Women with a history of treated ectopic pregnancy, either medically or surgically, demonstrated increased risk of developing placental abruption, hypertensive disorders of pregnancy, and preterm birth. History of ectopic pregnancy was also positively associated with low birth weight, subsequent ectopic pregnancy, and increased risk of a subsequent emergency cesarean section. Conclusions: The meta-analysis reveals evidence that ectopic pregnancy is positively associated with adverse perinatal outcomes in subsequent pregnancy. Our findings should be considered preliminary and serve as a basis for future research as the retrieved data are scarce and cannot be deemed sufficient. Full article

Pulmonary hypertension (PH) is a progressive lung disease characterized by abnormal pulmonary vascular pressure and right ventricular (RV) dysfunction. Atrial arrhythmias, including atrial fibrillation (AF) and atrial flutter, are common in patients with PH and significantly contribute to disease progression and mortality. A bidirectional pathophysiological link exists between PH and AF, encompassing shared mechanisms such as endothelial dysfunction, DNA damage, autophagy, inflammation, and oxidative stress, as well as mutual risk factors, including diabetes, obesity, heart disease, and aging. Despite these shared pathways, limited research has been conducted to fully understand the intertwined relationship between PH and AF, hindering the development of effective treatments. In this review, we provide a comprehensive overview of the epidemiology of PH, the molecular mechanisms underlying the development of AF in PH, and the overlap in their pathophysiology. We also identify novel druggable targets and propose mechanism-based therapeutic approaches to treat this specific patient group. By shedding light on the molecular connection between PH and AF, this review aims to fuel the design and validation of innovative treatments to address this challenging comorbidity. Full article

Background/Objectives: Multiple sclerosis (MS) is often associated with comorbidities that affect clinical outcomes. Data on comorbidities can be sourced from self-reports, medical records, and administrative databases. The gold standard for collecting such data is prospective clinical collection, as in clinical trials, but this is not feasible in large epidemiological studies. This study aimed to assess the agreement between two data sources, clinical interviews and administrative records, identifying major comorbidities in people with MS (pwMS). Methods: We evaluated the agreement between clinical interview data and administrative records in pwMS enrolled at two sites (2021–2022). Seven comorbidities were investigated: depression, anxiety, diabetes, hypertension, autoimmune disease, chronic lung disease, and hyperlipidemia. We used kappa (κ), sensitivity, specificity, and predictive values to assess agreement. Results: The frequency of comorbidities varied between the sources. Administrative data often underestimated hypertension, autoimmune diseases, hyperlipidemia, and anxiety, but over-reported depression. It had high sensitivity for diabetes (80%) and moderate sensitivity for hypertension (62%). The agreement for diabetes (κ = 98.9%, PABAK = 0.98, positive agreement = 83.3%) and hypertension (κ = 89.8%, PABAK = 0.80, positive agreement = 70.8%) was high. Conclusions: The agreement between administrative data and clinical interviews was excellent for diabetes and hypertension. For other conditions, such as psychiatric, hyperlipidemia, and autoimmune comorbidities, administrative data had lower sensitivity, and often under-reported or misclassified the data. Full article

Background/Objectives: Chronic kidney disease (CKD) affects 10 to 15% of the world population. Currently, there are no reliable epidemiological data on the prevalence of CKD in Poland. The aim of this study was to determine the prevalence of CKD in the population of high-risk primary health care patients without a prior diagnosis of CKD in the Polish population. Methods: This multicenter retrospective study examined 5100 patients from 28 medical institutions. Patients were eligible for the study if they were 60–75 years old or had a history of the risk factors such as hypertension, kidney disease other than CKD, diabetes, cardiovascular disease, or obesity. The study was carried out in two stages, each of which included a determination of serum creatinine levels along with an estimation of eGFR and a determination of albuminuria in a urine sample. Results: In total, 5100 patients were included in the final analysis. In the univariate analysis, it was found that as age and body mass index values increased, the risk of developing CKD increased; the same correlation was observed when assessing the presence of hypertension, diabetes, or heart failure. In the multivariate analysis, the negative effects of hypertension, age 60–75 years, diabetes, heart failure, cardiovascular diseases, and kidney disease other than CKD on the development of CKD were confirmed. Conclusions: The results indicate that CKD is a significant social problem among the Polish population with risk factors. Full article

Splanchnic vein thrombosis (SVT) is a heterogeneous group of disorders affecting the portal, mesenteric, splenic, and hepatic veins. While frequently associated with liver cirrhosis and malignancy, SVT also occurs in non-cirrhotic, non-neoplastic patients. This narrative review evaluates the epidemiology and risk factors for SVT in this population. The prevalence and incidence of SVT in non-cirrhotic, non-neoplastic patients remain incompletely characterized, with estimates varying widely across studies. The clinical significance of SVT relates to potential complications, including intestinal ischemia, portal hypertension, and a possible underlying systemic disorder. Risk factors for SVT can be categorized into local abdominal conditions, thrombophilias, and systemic disorders. Local factors include inflammatory bowel disease, pancreatitis, abdominal surgery, and trauma. Thrombophilias, both inherited and acquired, are significant contributors to SVT risk. Systemic conditions associated with SVT include autoimmune disorders, pregnancy, hematological diseases, and infections. The complex interplay of these risk factors highlights the need for a comprehensive evaluation of SVT patients. Early recognition and management of these conditions can prevent potentially life-threatening complications and guide decisions regarding anticoagulation and long-term follow-up. Full article
