Postpartum depression (PPD) is a severe mental health condition that affects women following childbirth and is marked by persistent sadness, anxiety, fatigue, and difficulty functioning. Unlike the temporary “baby blues”, PPD is more severe and long-lasting, potentially leading to negative consequences for mother and child. Globally, PPD impacts approximately 10–20% of postpartum women, with prevalence influenced by genetic, hormonal, psychological, and socio-environmental factors. Early detection is crucial, with screening tools such as the Edinburgh Postnatal Depression Scale (EPDS) commonly used in clinical practice. Treatment options include pharmacological interventions such as selective serotonin reuptake inhibitors (SSRIs), psychological therapies like cognitive behavioral therapy (CBT) and interpersonal therapy (IPT), and lifestyle modifications. Despite the growing awareness of PPD, stigma remains a significant barrier to treatment, discouraging many women from seeking help. In low-income countries, where mental health care is often underfunded, accessing professionals trained in perinatal mental health presents an even greater challenge. This gap underscores the urgent need for a collaborative, multidisciplinary approach involving obstetricians, psychiatrists, pediatricians, and midwives to ensure comprehensive support and care for affected individuals.

Prostate cancer (PCa) is one of the most common malignancies among men worldwide. While prostate-specific antigen (PSA) screening has improved early detection, it has also led to significant challenges regarding overdiagnosis and overtreatment. Overdiagnosis involves identifying indolent tumors unlikely to affect a patient’s lifespan, while overtreatment refers to unnecessary interventions that can cause adverse effects such as urinary incontinence, erectile dysfunction, and a reduced quality of life. This review highlights contributing factors, including the limitations of PSA testing, advanced imaging techniques like multi-parametric MRI (mpMRI), medical culture, and patient expectations. The analysis emphasizes the need for refining screening protocols, integrating novel biomarkers (e.g., PCA3, TMPRSS2-ERG), and adopting conservative management strategies such as active surveillance to minimize harm. Risk-based screening and shared decision-making are critical to balancing the benefits of early detection with the risks of unnecessary treatment. Additionally, systemic healthcare factors like financial incentives and malpractice concerns exacerbate overuse. This review advocates for updated clinical guidelines and personalized approaches to optimizing patient outcomes while reducing the strain on healthcare resources. Addressing overdiagnosis and overtreatment through targeted interventions will improve the quality of life for PCa patients and enhance the efficiency of healthcare systems.

Discoveries related to an intriguing feature of ubiquitination have prompted a detailed analysis of the ubiquitination patterns in malignant cells. How the “ubiquitinome” is reshaped during multistage carcinogenesis has garnered significant attention. Seminal studies related to the structural and functional characterization of NEDD4 (Neuronal precursor cell-expressed developmentally downregulated-4) have consolidated our understanding at a new level of maturity. Additionally, regulatory roles of non-coding RNAs have further complicated the complex interplay between non-coding RNAs and the members of NEDD4 family. These mechanisms range from the miRNA-mediated targeting of NEDD4 family members to the regulation of transcriptional factors for a broader range of non-coding RNAs. Additionally, the NEDD4-mediated degradation of different proteins is modulated by lncRNAs and circRNAs. The miRNA-mediated targeting of NEDD4 family members is also regulated by circRNAs. Tremendous advancements have been made in the identification of different substrates of NEDD4 family and in the comprehensive analysis of the molecular mechanisms by which various members of NEDD4 family catalyze the ubiquitination of substrates. In this review, we have attempted to summarize the multifunctional roles of the NEDD4 family in cancer biology, and how different non-coding RNAs modulate these NEDD4 family members in the regulation of cancer. Future molecular studies should focus on the investigation of a broader drug design space and expand the scope of accessible targets for the inhibition/prevention of metastasis.

Background: Equitable access to kidney replacement therapy (KRT) remains a major challenge for patients living in geographically isolated, rural, and underserved settings. Organizational approaches, including tele-nephrology, remote patient monitoring, decentralized dialysis services, home dialysis support, rural outreach programs, and emergency preparedness strategies, have been increasingly used to address geographic and organizational barriers to KRT delivery. This review summarizes the available evidence on organizational approaches supporting remote and decentralized KRT delivery and examines their reported implications for healthcare accessibility, continuity of care, and service delivery. Methods: A structured literature search was conducted in PubMed/MEDLINE, Scopus, Web of Science Core Collection, and the Cochrane Library for studies published between January 2016 and January 2026. Publications considered relevant addressed organizational, healthcare delivery, implementation, or health-system approaches supporting KRT accessibility, continuity, or delivery in geographically isolated, rural, underserved, disaster-affected, humanitarian, or resource-limited settings. Studies describing conventional facility-based dialysis without an organizational or healthcare delivery component were excluded. Relevant information on study characteristics, KRT modality, organizational approaches, implementation components, healthcare accessibility, continuity of care, and reported barriers and outcomes was extracted and narratively synthesized. Results: A total of 749 records were identified, and 12 publications were retained for detailed synthesis. The publications addressed tele-nephrology, remote monitoring, home dialysis support, rural outreach, decentralized and community-based dialysis, and emergency preparedness. Study designs, settings, organizational models, and outcomes varied substantially. Reported findings concerned specialist access, home and decentralized dialysis pathways, dialysis continuity, healthcare utilization, and implementation feasibility. Most publications were observational, pilot, implementation-based, or qualitative, limiting causal inference and direct comparison across settings. Conclusions: The literature describes organizational approaches that may address specific barriers to KRT access and continuity. However, heterogeneous and predominantly non-comparative evidence is insufficient to establish causal effectiveness or superiority of any specific model. Multicenter comparative studies with standardized organizational, patient-centered, and economic outcomes are needed to assess effectiveness, scalability, and sustainability.

Background: Immunoglobulin A nephropathy is among the most commonly observed glomerular disorders. Its development is associated with immune dysfunction, which initiates a cascade of pathological changes within the glomeruli. The clinical course can range from minimal urinary abnormalities to progressive renal impairment, potentially culminating in end-stage kidney disease. Despite considerable advances in understanding its pathogenesis, optimal therapeutic strategies remain an active focus of scientific investigation. Aim: To assess current and emerging therapeutic strategies for IgA nephropathy, with an emphasis on efficacy, safety, and the potential of targeted agents addressing key pathogenic pathways. Methods: We conducted a narrative review of recent literature in PubMed, Scopus, Web of Science, and eLIBRARY databases, focusing on publications from the last decade. Studies published in English and Russian that reported results from clinical trials or meta-analyses on therapeutic interventions for IgA nephropathy were included. Search terms included «IgA nephropathy», «treatment», «targeted therapy», «new therapies», «immunosuppressants», and «clinical trials». Priority was given to randomized controlled trials and studies with high-quality evidence, though relevant observational data were also considered. Results: Key studies identified included 52 publications, among which 20 were randomized clinical trials and a systematic review. Corticosteroid therapy remains a cornerstone of treatment but is limited by significant adverse effects. Recent therapeutic developments in IgA nephropathy have focused on interventions that selectively target inflammatory and immune pathways involved in disease progression. Certain novel agents aimed at modulating immune signaling or addressing pathogenic plasma cells have shown potential to reduce proteinuria and stabilize renal function. Early-phase clinical investigations indicate promising efficacy and manageable safety profiles, suggesting these approaches may represent important advances in disease management. Conclusions: Recent progress in targeted and immunomodulatory therapies offers new perspectives for personalized treatment of IgA nephropathy. Comprehensive, large-scale randomized studies with extended follow-up are warranted to thoroughly assess the therapeutic potential, safety profile, and optimal positioning of these interventions within future clinical management strategies.
