Molecular cytogenetic analysis of cutaneous T-cell lymphomas: identification of common genetic alterations in Sézary syndrome and mycosis fungoides.

This review summarizes current evidence on the biological, diagnostic, prognostic, and therapeutic significance of microRNAs (miRNAs/miRs) in prostate cancer (PCa). Dysregulated miRNA networks contribute to PCa initiation, progression, metastasis, and therapy resistance by regulating androgen receptor signaling, proliferation, apoptosis, epithelial-mesenchymal transition, angiogenesis, hypoxia signaling, bone tropism, and castration-resistant evolution. Oncogenic miRNAs, including miR-21, miR-93, miR-9, miR-181a, and miR-182, promote malignant phenotypes through survival, TGF-β, PI3K/AKT, MAPK

Depressive symptom trajectories among general population during the COVID-19 pandemic in Iceland: a prospective cohort study (2020-2023).

IntroductionWhile changes in the prevalence of depressive symptoms during the COVID-19 pandemic have been described across populations, few studies have incorporated multidimensional variables to characterise the varying effects of the pandemic on the population's mental health.MethodsThis cohort study included 6423 participants aged ≥18 years from the Icelandic COVID-19 National Resilience Cohort. Data on depressive symptoms and pandemic-related and non-pandemic-related factors were obtained during three pandemic assessment periods (baseline, follow-up wave 1 and follow-up wave 2; April 2020-

Breaking into HIV-1's Epigenetic Vault: Cure Strategies to Eliminate the Viral Reservoir.

Human immunodeficiency virus type 1 (HIV-1) is a retrovirus that integrates into the host cell's DNA as a provirus. Transcription from the provirus is regulated in large part by cellular proteins and epigenetic factors. These may be repressive or permissive to productive infection. The host factors that regulate this balance are therefore attractive targets for HIV-1 therapeutics. Indeed, proviral chromatin is the focus of two of the current HIV-1 cure strategies. "Shock and Kill" uses latency reversal agents to open the provirus's chromatin, promoting high levels of gene expression that induc

IL-22 способствует возникновению хронической гаммагерпесвирусной инфекции, поддерживая реакцию микробного центра.

Гаммагерпесвирусы, включая вирус Эпштейн-Барр (EBV) и герпесвирус, связанный с Карпози (KSHV), создают скрытые инфекции на протяжении всей жизни, которые способствуют множественным заболеваниям раком и множественным склерозом. Эти вирусы колонизируют наивные клетки B и приводят в действие мощный, поликлонный герминальный центр, чтобы расширить латентный вирусный резервуар и установить пожизненную инфекцию в клетках памяти B. Несмотря на клиническое бремя этих вирусов, факторы, способствующие хронической инфекции, по-прежнему плохо определены. " Interleukin-22 " (IL-22) является крити

Alignment of preferences in the treatment of multiple myeloma - a discrete choice experiment of patient, carer, physician, and nurse preferences.

BACKGROUND: Multiple Myeloma (MM) is a cancer characterised by the proliferation of malignant plasma cells in the bone marrow. This study examined the treatment preferences of people living with MM compared to the treatment preferences of other groups involved in treatment decision making, including carers, as well as physicians and nurses who treat people living with MM in Australia. METHODS: Data were collected using discrete choice experiments (DCEs) through an online survey. The DCEs presented participants with a traditional treatment generic choice experiment (e.g., treatment A vs treatm

Control of viral infections by epigenetic-targeted therapy.

Epigenetics is defined as the science that studies the modifications of gene expression that are not owed to mutations or changes in the genetic sequence. Recently, strong evidences are pinpointing toward a solid interplay between such epigenetic alterations and the outcome of human cytomegalovirus (HCMV) infection. Guided by the previous possibly promising experimental trials of human immunodeficiency virus (HIV) epigenetic reprogramming, the latter is paving the road toward two major approaches to control viral gene expression or latency. Reactivating HCMV from the latent phase ("shock and k

Ex vivo drug response heterogeneity reveals personalized therapeutic strategies for patients with multiple myeloma.

Multiple myeloma (MM) is a plasma cell malignancy defined by complex genetics and extensive patient heterogeneity. Despite a growing arsenal of approved therapies, MM remains incurable and in need of guidelines to identify effective personalized treatments. Here, we survey the ex vivo drug and immunotherapy sensitivities across 101 bone marrow samples from 70 patients with MM using multiplexed immunofluorescence, automated microscopy and deep-learning-based single-cell phenotyping. Combined with sample-matched genetics, proteotyping and cytokine profiling, we map the molecular regulatory netwo

Дело о том, что скрытая и литичная инфекция Эпштейна-Барра была направлена на множественный склероз.

Вирус Эпштейн-Барр (EBV) тесно связан с множественным склерозом (MS). Он, вероятно, сыграет причинно-следственную роль в патогенезе MS, возможно, путем инициирования автономного иммунитета с помощью молекулярной имитации, автоантигенного представления или регулирования иммунной дистрибьюции. С другой стороны, имеющиеся данные подтверждают прямую роль ЭБВ в стимулировании деятельности по болезням MS посредством скрытых литических инфекций в циклическом режиме либо в рамках ЦНС, либо на периферии. Мы обращаем особое внимание на недавние иммунологические и вирологические выводы, подтверждающие ро

KSHV and cancer: understanding the oncogenic machinery for next-generation diagnostic tools and therapies.

Kaposi's sarcoma-associated herpesvirus (KSHV), or human herpesvirus 8 (HHV-8), is an oncogenic virus responsible for Kaposi's sarcoma (KS) and lymphoproliferative disorders like primary effusion lymphoma (PEL) and multicentric Castleman disease (MCD). This review explores KSHV's oncogenic mechanisms, focusing on its ability to manipulate host cell signaling, evade immune detection, and promote tumorigenesis through latent and lytic viral proteins. Key oncoproteins, such as LANA, vCyc, vFLIP, and vGPCR, activate cancer hallmarks, as sustained proliferation, immune evasion, angiogenesis, and re

Physical activity-related health competence and symptom burden for exercise prescription in patients with multiple myeloma: a latent profile analysis.

The purpose of this study is to ensure best possible supply of exercise therapy to patients with multiple myeloma (MM); it is helpful to identify patient groups with similar symptom burden and physical activity-related health competences (PAHCO). Latent profile analyses (LPA) of MM patients were used to identify profiles of patients with similar PAHCO and symptom burden. Analysis of variance was applied to investigate group differences in important covariates. N = 98 MM patients (57% male, age 64 ± 9 years) could be assigned to three distinct PAHCO profiles: 46% were patients with high PAHCO,

Рассеивание плериотропии между серьезным депрессивным расстройством и сопутствующими заболеваниями.

Серьезное депрессивное расстройство (МДС) характеризуется значительной совместимостью с медицинскими заболеваниями. Для достижения более высоких результатов для пациентов, страдающих ДМЗ, требуется более глубокое понимание механизмов, лежащих в основе широко распространенных комординаций. Здесь, с этой целью, мы нарисовали рисунки плейотропии, определив four - группы физических заболеваний (сердечные, метаболические, желудочно-кишечные и иммунные) и анализ их генетических связей с MDD с использованием геномного структурного уравнения моделирования.

Аналитическая проверка множественного пептида для многоантигенного серологического профилирования вируса Эпштейн-Барр по различным клиническим образцам.

Вирус Эпштейн-Барр (ЭБВ) заражает более 95% взрослых и связан с различными результатами: от асимптомной запоздалости до инфекционного мононуклеоза (IM), малигнации и множественного склероза (MS). Обычная серология, основанная на ЭЛИСА, часто ограничивается небольшим количеством растворимых, цельнопротеиновых антигенов и не сохраняет информацию о конкретных линейных районах обнаружения антигенов, которые способствуют общей реакции антител. Множественные пептидные микроархивы устраняют это ограничение, однако их использование в клинической практике требует характеристики их аналитических характе

Prevention of CMV/EBV reactivation by double-specific T cells in patients after allogeneic stem cell transplantation: results from the randomized phase I/IIa MULTIVIR-01 study.

INTRODUCTION: Allogeneic stem cell transplantation is used to cure hematologic malignancies or deficiencies of the hematopoietic system. It is associated with severe immunodeficiency of the host early after transplant and therefore early reactivation of latent herpesviruses such as CMV and EBV within the first 100 days are frequent. Small studies and case series indicated that application of herpes virus specific T cells can control and prevent disease in this patient population. METHODS: We report the results of a randomized controlled multi centre phase I/IIa study (MULTIVIR-01) using a new

Alcohol Misuse in Older Women: A Scoping Review of Correlates, Consequences, Treatment, and Prevention.

BackgroundAlcohol use and alcohol use disorder (AUD) among older women (defined as age 50 and over) have increased substantially in recent years. Compared to men and younger women, older women negotiate biopsychosocial transitions that put them at greater risk of alcohol-related health conditions as they age and are less reliably screened and treated for heavy alcohol use and AUD.ObjectivesThis scoping review represents a critical evaluation of research methodology and findings since 2004 on biopsychosocial correlates and consequences of alcohol misuse (i.e., heavy alcohol use, defined as four

Medicaid Formulary Decisions and the Institute for Clinical and Economic Review: Abandoning Pseudoscience in Imaginary Pharmaceutical Pricing Claims.

Medicaid formulary committees and other gatekeepers face a difficult task. On the one hand they can utilize technical expertise in evaluating the real world evidence for clinical, quality of life and resource utilization claims for competing products while on the other hand they may be asked to assess claims built by simulation models for pricing and product access. A common option has been to take modeled claims from third parties such as the Institute for Clinical and Economic Review (ICER) at face value without challenging the model structure, its assumptions and its incremental cost-per-QA

Lost in transcription: molecular mechanisms that control HIV latency.

Highly active antiretroviral therapy (HAART) has limited the replication and spread of the human immunodeficiency virus (HIV). However, despite treatment, HIV infection persists in latently infected reservoirs, and once therapy is interrupted, viral replication rebounds quickly. Extensive efforts are being directed at eliminating these cell reservoirs. This feat can be achieved by reactivating latent HIV while administering drugs that prevent new rounds of infection and allow the immune system to clear the virus. However, current approaches to HIV eradication have not been effective. Moreover,
