A review on how to do hematology consults during COVID-19 pandemic.

The ongoing COVID-19 pandemic is the most trending and talked topic across the World. From its point of origin in Wuhan, China to clinical laboratory at NIH, a mere six-month-old SARS-CoV-2 virus is keeping the clinicians, and scientists busy at various fronts. However, COVID-19 is an emerging and evolving disease and each day brings in more data, new figures, and findings from the field of clinical practice. The role of hematologists has been increasingly recognized during the current pandemic because of several reasons. Most important of them are the characteristic hematological findings of

Leptomeningeal disease: current diagnostic and therapeutic strategies.

OBJECTIVES: We determined the efficacy of the use of a tension free prolene mesh to correct a grade III anterior vaginal wall prolapse recurrence. METHODS: Twelve women (mean age 65.6 years) with stress urinary incontinence (SUI) (4 type II and 1 type III) and bladder prolapse entered the study. After vaginal incision a pretailored polypropylene mesh was fixed to its four angles by absorbable sutures to the urethropelvic ligaments and pubocervical fascia anteriorly and to the cardinal ligaments and pubocervical fascia posteriorly. When present, a posterior descensus was corrected during the s

From Development, Disease, and Decline: A Review of What Defines an Osteoclast Progenitor.

Our understanding of the different developmental origins of osteoclast progenitors and their respective roles during homeostatic bone remodeling at different skeletal sites as well as their roles within bone regeneration and degenerative conditions is evolving. In this narrative review article, we summarize what is known about the developmental origins, anatomical sources, and markers of osteoclast progenitors. We touch on how osteoclast progenitors vary during different disease contexts, including periodontitis, rheumatoid arthritis, and osteoarthritis. In addition, we also characterize osteo

Rhabdomyolysis secondary to COVID-19 infection and vaccination: a review of literature.

Rhabdomyolysis (RML), characterized by the breakdown of skeletal muscle fibers and the release of muscle contents into the bloodstream, has emerged as a notable complication associated with Coronavirus disease 2019 (COVID-19) infection and vaccination. Studies have reported an increased incidence of RML in individuals with severe COVID-19 infection. However, the exact mechanisms remain unclear and are believed to involve the host's immune response to the virus. Furthermore, RML has been documented as a rare adverse event following COVID-19 vaccination, particularly with mRNA vaccines. Proposed

Cell-Selective Altered Cargo Properties of Extracellular Vesicles Following In Vitro Exposures to Intermittent Hypoxia.

Intermittent hypoxia (IH), a hallmark of obstructive sleep apnea (OSA), is associated with cardiovascular and metabolic dysfunction. However, the mechanisms underlying these morbidities remain poorly delineated. Extracellular vesicles (EVs) mediate intercellular communications, play pivotal roles in a multitude of physiological and pathological processes, and could mediate IH-induced cellular effects. Here, the effects of IH on human primary cells and the release of EVs were examined. Microvascular endothelial cells (HMVEC-d), THP1 monocytes, THP1 macrophages M0, THP1 macrophages M1, THP1 macr

Clinical management of cancer after kidney transplantation.

Advances in immunosuppressive therapy have markedly improved short-term graft survival post-kidney transplantation (KT); however, these advances have also profoundly altered long-term disease patterns in transplant recipients. Cancer remains a major barrier limiting improvements in long-term survival. Kidney transplant recipients are at increased risk of malignancy owing to impaired graft function and immunosuppressive medications. To improve cancer-related outcomes, comprehensive strategies encompassing prevention, early detection through screening, and appropriate treatment are required. Pri

Innovative Approaches in Bone Tissue Engineering: Strategies for Cancer Treatment and Recovery.

Cancer has rapidly emerged as a leading global cause of premature mortality, with significant economic implications projected to reach USD 25.2 trillion from 2020 to 2050. Among the various types of cancer, primary bone cancers, though uncommon, are projected to see nearly 4000 new cases diagnosed in the United States in 2024. The complexity of treating bone cancer arises from its rarity, diversity, and the challenges associated with surgical interventions, metastatic spread, and post-operative complications. Advancements in bone tissue engineering (BTE) have introduced innovative therapeutic

Prevalence, Attributes, and Risk Factors of QT-Interval-Prolonging Drugs and Potential Drug-Drug Interactions in Cancer Patients: A Prospective Study in a Tertiary Care Hospital.

Introduction Cancer chemotherapy regimens include multiple classes of adjuvant drugs as supportive therapy. Because of the concurrent intake of other drugs (like antiemetics, antidepressants, analgesics, and antimicrobials), there is a heightened risk for possible QT interval prolongation. There is a dearth of evidence in the literature regarding the usage of QT-prolonging anticancer drugs and associated risk factors that have the propensity to prolong QT interval. The purpose was to explore the extent of the use of QT-interval-prolonging drugs and potential QT-prolonging drug-drug interaction

It summarizes current evidence a

Assessment of TSPAN Expression Profile and Their Role in the VSCC Prognosis.

The role and prognostic value of tetraspanins (TSPANs) in vulvar squamous cell carcinoma (VSCC) remain poorly understood. We sought to primarily determine, at both the molecular and tissue level, the expression profile of the TSPANs CD9, CD63, CD81, and CD82 in archived VSCC samples (n = 117) and further investigate their clinical relevance as prognostic markers. Our studies led us to identify CD63 as the most highly expressed TSPAN, at the gene and protein levels. Multicomparison studies also revealed that the expression of CD9 was associated with tumor size, whereas CD63 upregulation was ass

The Rise of Oncoendocrinology: How Modern Cancer Therapies Are Reshaping Endocrine Practice.

The emergence of immune checkpoint inhibitors, targeted therapies, CAR T-cell therapy, and antibody-drug conjugates has transformed modern oncology, significantly improving survival across a wide range of malignancies. However, these advances have also introduced a growing spectrum of endocrine and metabolic complications, redefining the scope of endocrine practice. Therapy-induced endocrinopathies, including thyroid dysfunction, hypophysitis, adrenal insufficiency, diabetes, pancreatitis, dyslipidemia, gonadal dysfunction, and metabolic syndrome, are recognized as clinically significant and o

Liver replacement therapy with extracorporeal blood purification techniques current knowledge and future directions.

Clinically, it is highly challenging to promote recovery in patients with acute liver failure (ALF) and acute-on-chronic liver failure (ACLF). Despite recent advances in understanding the underlying mechanisms of ALF and ACLF, standard medical therapy remains the primary therapeutic approach. Liver transplantation (LT) is considered the last option, and in several cases, it is the only intervention that can be lifesaving. Unfortunately, this intervention is limited by organ donation shortage or exclusion criteria such that not all patients in need can receive a transplant. Another option is to

Control of Breast Cancer Pathogenesis by Histone Methylation and the Hairless Histone Demethylase.

Breast cancer is a highly heterogeneous disease, encompassing many subtypes that have distinct origins, behaviors, and prognoses. Although traditionally seen as a genetic disease, breast cancer is now also known to involve epigenetic abnormalities. Epigenetic regulators, such as DNA methyltransferases and histone-modifying enzymes, play essential roles in gene regulation and cancer development. Dysregulation of epigenetic regulator activity has been causally linked with breast cancer pathogenesis. Hairless (HR) encodes a 130-kDa transcription factor that is essential for development and tissue

Primary Aggressive Oral Lymphomas (PAOL): A Narrative Review of Diagnosis, Molecular Features, Therapeutic Approaches, and the Integrated Role of Dentists and Hematologists.

Primary aggressive oral lymphomas (PAOL) are a rare subset of extranodal non-Hodgkin lymphomas arising in the oral cavity without evidence of other systemic involvement at diagnosis. PAOL accounts for only about 2-3% of all lymphomas. They most commonly belong to aggressive B-cell subtypes such as Diffuse large B-cell lymphoma (DLBCL) and plasmablastic lymphoma (PBL), with occasional cases of Burkitt lymphoma and T-cell/NK-cell lymphomas. Clinically, these malignancies often present with non-specific symptoms (e.g., swelling, pain, ulceration, tooth mobility) that mimic benign dental condition

Targeting the ROCK2/UBA52/DRP1 axis enhances ferroptosis and overcomes pemigatinib resistance in Cholangiocarcinoma.

Cholangiocarcinoma (CCA) is a highly aggressive cancer that arises from the bile duct and has an extremely poor prognosis. Pemigatinib is the only Food and Drug Administration (FDA)-approved CCA-targeted drug. The CCA treatment options are insufficient considering its poor prognosis and increasing morbidity. Recently, Rho-associated coiled-coil containing protein kinase 2 (ROCK2) has been reported to promote resistance to chemotherapy. In this study, we investigated the role that ROCK2 plays in the development of resistance of CCA cells to Pemigatinib. Here, we developed Pemigatinib-resistant

Histone H3K18 Lactylation Promotes the Malignant Progression of Wilms Tumor via a PSRC1/AKT/HIF-1α Positive Feedback Loop.

Nephroblastoma, also known as Wilms tumor (WT), is the most common pediatric renal malignancy. Current treatment regimens exhibit limited efficacy in high-risk patients and are associated with long-term adverse effects. Through gene set enrichment analysis (GSEA) and validation using clinical specimens, we identified aberrant glycolytic activity in WT, which drives lactate accumulation. Lactate is not merely a metabolic byproduct but also a critical epigenetic regulator that mediates histone lactylation; however, its functional role in WT remains uncharacterized. In this study, we found that t

Гут Микробиом и мальгический энцефаломилит/хронический синдром утомления (ME/CFS): Понимание механизмов борьбы с заболеваниями.

Myalgic Encephalomyelitis/Chronic Fatige (ME/CFS) — клиническая болезнь, характерная особенность которой заключается в постэкспертальной болезни (PEM). Она может влиять на многие органы и системы, что приводит к серьезному ухудшению качества жизни пациентов. Несмотря на многочисленные постинфекционные, иммунологические, неврологические, метаболические и эндокринные изменения, не существует ни окончательного диагностического маркера, ни утвержденного лечения. Этиология и патофизиология по-прежнему не до конца понимаются; однако появляющиеся данные свидетельствуют о том, что кишечная микробиомия

ЦАРТ клетки в качестве новой терапевтической стратегии для множественных склерозов и других нейроиммунных расстройств.

В качестве трансформационного подхода к лечению множественных склерозов (MS) и других нейроиммунных расстройств, таких, как расстройства спектра нейромиелита (NMOSD), миелин олигодендроцита гликпротеина, связанных с антителами (MOGAD), и миастения гравис (MG), наряду с рядом других редких нейроиммунологических заболеваний, которые в настоящее время оцениваются в исследованиях, посвященных сочувствию или ранней фазе. Отчасти эти условия обусловлены автоматически реактивными клетками B, вызывающими хроническое воспаление и прогрессивное повреждение тканей. Несмотря на то, что нынешняя иммунодуля

The therapeutic potential of colchicine in oncology studies: from structural modification and targeted delivery to clinical management.

Colchicine, a classical microtubule-targeting agent (MTA), exhibits remarkable anti-tumor potential, but its clinical translation is severely restricted by a narrow therapeutic window, systemic off-target toxicity, and complex pharmacokinetic vulnerabilities. Driven by the objective of "toxicity reduction and efficacy enhancement," this review comprehensively summarizes colchicine's multidimensional translational research. First, precise chemical modifications of its tricyclic scaffold and multi-site synergistic strategies are analyzed, exploring structure-activity relationship (SAR) mechanism
