New Approaches in Oncology for Repositioning Drugs: The Case of PDE5 Inhibitor Sildenafil.

The use of already-approved drugs to treat new or alternative diseases has proved to be beneficial in medicine, because it reduces both drug development costs and timelines. Most drugs can be used to treat different illnesses, due their mechanisms of action are not restricted to one molecular target, organ or illness. Diverging from its original intent offers an opportunity to repurpose previously approved drugs to treat other ailments. This is the case of sildenafil (Viagra), a phosphodiesterase-5 (PDE5) inhibitor, which was originally designed to treat systemic hypertension and angina but is

Optimizing treatment efficacy and fertility preservation in patients undergoing hematopoietic stem cell transplantation: A narrative review of ovarian shielding with total-body irradiation or treosulfan-based conditioning regimens.

BackgroundPediatric and adolescent/young adult (AYA) patients with hematologic malignancies often require hematopoietic stem cell transplantation (HSCT) using conditioning regimens that pose high risks for gonadal toxicity. Traditional protocols, including total body irradiation (TBI) and busulfan-based regimens, can impair fertility. This review explores the potential of gonadal shielding during TBI and treosulfan-based conditioning as strategies to optimize treatment efficacy while preserving fertility.MethodsA PubMed search up to February 2025 was performed for English, peer-reviewed articl

Генетическая основа болезни.

Генетика в той или иной степени играет определенную роль во всех заболеваниях. Изменения в нашей ДНК и различия в том, как эта ДНК функционирует (одиночка или комбинация), наряду с окружающей средой (которая включает образ жизни), способствуют болезнетворным процессам. В рамках этого обзора изучается генетическая основа человеческих заболеваний, включая однородные генетические расстройства, хромосомные диспропорции, эпигенетические, раковые и сложные расстройства, и рассматривается вопрос о том, каким образом наше понимание и технологические достижения могут быть использованы для обеспечения н

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

… Puberty is defined as the onset of sexual maturity indicated by the ability to bear viable young, and it occurs before full body size and weight are attained. As in most species, puberty occurs in females earlier than in males and also varies with stock or strain. … Caloric restriction, a 15–30% decrease from ad libitum caloric intake, may cause cessation of estrous cycles and delayed sexual maturation ( Fox and Laird, 1970 ). …

Psychopathological Aspects in Childhood Hematopoietic Stem Cell Transplantation (HSCT): The Perception of Parents and Adolescents.

Background: Data about psychosocial sequelae of childhood Hematopoietic Stem Cell Transplantation (HSCT) are limited and the association with a specific donor type or other medical factors is largely unknown (Chang et al., 2012). The aim of the present study was to compare the psychological aspects of pediatric HSCT survivors with healthy peers. A secondary aim was to detect whether parents and children differed in the perception of mental health status. The influence of medical factors on psychological status was also examined. Method: Thirty seven HSCT survivors (23 males) with a mean age of

Gene regulation by non-Coding RNAs in infertility: a mechanistic review.

Infertility is a significant global health issue affecting millions of couples, with noncoding RNAs (ncRNAs) emerging as pivotal regulators in reproductive biology. This review explores the roles of various ncRNAs, including microRNAs (miRNAs), small interfering RNAs (siRNAs), long noncoding RNAs (lncRNAs), PIWI-interacting RNAs (piRNAs), and circular RNAs (circRNAs) in male and female infertility. These ncRNAs modulate critical processes such as spermatogenesis, oogenesis, follicular development, and embryo implantation through mechanisms like post-transcriptional regulation, chromatin remode

Melatonin-micronutrients Osteopenia Treatment Study (MOTS): a translational study assessing melatonin, strontium (citrate), vitamin D3 and vitamin K2 (MK7) on bone density, bone marker turnover and health related quality of life in postmenopausal osteopenic women following a one-year double-blind RCT and on osteoblast-osteoclast co-cultures.

This one-year double blind randomized control trial assessed the effects of nightly melatonin, strontium (citrate), vitamin D3 and vitamin K2 (MK7; MSDK) on bone mineral density (BMD) and quality of life (QOL) in postmenopausal osteopenic women (ages 49-75). Compared to placebo, MSDK treatment increased BMD in lumbar spine (4.3%) and left femoral neck (2.2%), with an upward trend for total left hip (p=0.069). MSDK increased serum P1NP levels and reduced bone turnover (CTx:P1NP). Psychometric analyses indicated that mood and sleep quality improved for the MSDK group. MSDK-exposed human mesenchy

Clinical Treatment Guidelines for Tafasitamab Plus Lenalidomide in Patients with Relapsed or Refractory Diffuse Large B-Cell Lymphoma.

Diffuse large B-cell lymphoma (DLBCL) accounts for approximately 24% of new cases of B-cell non-Hodgkin lymphoma in the US each year. Up to 50% of patients relapse or are refractory (R/R) to the standard first-line treatment option, R-CHOP. The anti-CD19 monoclonal antibody tafasitamab, in combination with lenalidomide (LEN), is an NCCN preferred regimen for transplant-ineligible patients with R/R DLBCL and received accelerated approval in the US (July 2020) and conditional marketing authorization in Europe (August 2021) and other countries, based on data from the L-MIND study. The recommended

An overview of cancer health disparities: new approaches and insights and why they matter.

Cancer health disparities remain stubbornly entrenched in the US health care system. The Affordable Care Act was legislation to target these disparities in health outcomes. Expanded access to health care, reduction in tobacco use, uptake of other preventive measures and cancer screening, and improved cancer therapies greatly reduced cancer mortality among women and men and underserved communities in this country. Yet, disparities in cancer outcomes remain. Underserved populations continue to experience an excessive cancer burden. This burden is largely explained by health care disparities, lif

Qualitative Analysis of Colorectal Cancer Screening in Rural Nebraska.

Compared to urban residents, rural populations are less likely to engage in colorectal cancer (CRC) screening. As part of a statewide cancer needs assessment, we aimed to elicit rural perspectives about CRC screening and resources. We conducted three focus groups with rural Nebraska cancer survivors and caregivers (N = 20) in Spring 2021 using a collective case study design. Participant awareness of and knowledge about CRC screening methods varied across focus groups; overall, 95% of participants had heard of colonoscopy. Participants were less familiar with fecal tests and had confusion about

Common Non-Rheumatic Medical Conditions Mimicking Fibromyalgia: A Simple Framework for Differential Diagnosis.

Fibromyalgia (FM) is a chronic non-inflammatory disorder mainly characterized by widespread musculoskeletal pain, fatigue, sleep disturbances, and a constellation of other symptoms. For this reason, delineating a clear distinction between pure FM and FM-like picture attributable to other common diseases can be extremely challenging. Physicians must identify the most significant confounders in individual patients and implement an appropriate diagnostic workflow, carefully choosing a minimal (but sufficient) set of tests to be used for identifying the most plausible diseases in the specific case

A Novel Intravesical Dextrose Injection Improves Lower Urinary Tract Symptoms on Interstitial Cystitis/Bladder Pain Syndrome.

Interstitial cystitis/bladder pain syndrome (IC/BPS) is a painful recurrent condition characterized by the discomfort of the bladder, and current treatment options have limited effectiveness. Prolotherapy is a well-known treatment that involves the injection of non-biologic solutions to reduce pain and/or promote proliferation of soft tissue, and dextrose is the most common injectate. This study investigated the effects of dextrose prolotherapy in a rat model of IC/BPS and patients with IC/BPS. We used cyclophosphamide to induce IC/BPS in rats, and intravesical instillation of 10% dextrose sol

Chemotherapeutic agents for the treatment of hepatocellular carcinoma: efficacy and mode of action.

Hepatocellular carcinoma (HCC) is a dreaded malignancy that every year causes half a million deaths worldwide. Being an aggressive cancer, its incidence exceeds 700,000 new cases per year worldwide with a median survival of 6-8 months. Despite advances in prognosis and early detection, effective HCC chemoprevention or treatment strategies are still lacking, therefore its dismal survival rate remains largely unchanged. This review will characterize currently available chemotherapeutic drugs used in the treatment of HCC. The respective mode(s) of action, side effects and recommendations will be
