Given the rate of advancement in predictive psychiatry, there is a threat that it outpaces public and professional willingness for use in clinical care and public health. Prediction tools in psychiatry estimate the risk of future development of mental health conditions. Prediction tools used with young populations have the potential to reduce the worldwide burden of depression.

Providing Mental Health and Psychosocial Support interventions (MHPSS) for forcibly displaced Ukrainians in Central and Eastern Europe poses numerous challenges due to various socio-cultural and infrastructural factors. This qualitative study explored implementation barriers reported by service providers of in-person and digital MHPSS for Ukrainian refugees displaced to Poland, Romania and Slovakia due to the war. In addition, the study aimed to generate recommendations to overcome these barriers.

Clinical Pharmacology Laboratory, Facultad de Estudios Superiores Zaragoza, Universidad Nacional Autónoma de México, Mexico City 09230, Mexico.

Sepsis and septic shock are major complications of febrile neutropenia (FN) in pediatric patients with cancer (PPCs). The aim of the present study was to determine the association of vitamin D (VD) and cathelicidin levels with sepsis and septic shock in PPCs with FN. A prospective cohort of PPCs with FN who had previously received cytotoxic chemotherapy was analyzed.

EBV-specific T-cell immunity: relevance for multiple sclerosis.

Front Immunol

December 2024

Department of Neurology with Institute of Translational Neurology, University Hospital Münster, Münster, Germany.

Genetic and environmental factors jointly determine the susceptibility to develop multiple sclerosis (MS). Improvements in the design of epidemiological studies have helped to identify consistent environmental risk associations such as the increased susceptibility for MS following Epstein-Barr virus (EBV) infection, while biological mechanisms that drive the association between EBV and MS remain incompletely understood. An increased and broadened repertoire of antibody and T-cell immune responses to EBV-encoded antigens, especially to the dominant CD4 T-cell EBV nuclear antigen 1 (EBNA1), is consistently observed in patients with MS, indicating that protective EBV-specific immune responses are deregulated in MS and potentially contribute to disease development.

Dysfunction in fear and stress responses is intrinsically linked to various neurological diseases, including anxiety disorders, depression, and Post-Traumatic Stress Disorder. Previous studies using in vivo models with Immediate-Extinction Deficit (IED) and Stress Enhanced Fear Learning (SEFL) protocols have provided valuable insights into these mechanisms and aided the development of new therapeutic approaches. However, assessing these dysfunctions in animal subjects using IED and SEFL protocols can cause significant pain and suffering.

Advancements and applications of artificial intelligence in cardiovascular imaging: a comprehensive review.

Eur Heart J Imaging Methods Pract

October 2024

Cardiologia 1-Emodinamica, Dipartimento Cardiotoracovascolare 'A. De Gasperis', ASST Grande Ospedale Metropolitano Niguarda, Milano, Italy.

Artificial intelligence (AI) is transforming cardiovascular imaging by offering advancements across multiple modalities, including echocardiography, cardiac computed tomography (CCT), cardiovascular magnetic resonance (CMR), interventional cardiology, nuclear medicine, and electrophysiology. This review explores the clinical applications of AI within each of these areas, highlighting its ability to improve patient selection, reduce image acquisition time, enhance image optimization, facilitate the integration of data from different imaging modality and clinical sources, improve diagnosis and risk stratification. Moreover, we illustrate both the advantages and the limitations of AI across these modalities, acknowledging that while AI can significantly aid in diagnosis, risk stratification, and workflow efficiency, it cannot replace the expertise of cardiologists.

Advances in adhesive hydrogels applied for ophthalmology: An overview focused on the treatment.

Theranostics

January 2025

Department of Ophthalmology, The First Affiliated Hospital of University of South China, Hengyang Medical School, University of South China, Hengyang Hunan 421001, China.

Adhesive hydrogels, composed of hydrophilic polymers arranged in a three-dimensional network, have emerged as a pivotal innovation in ophthalmology due to their ability to securely adhere to ocular tissues while providing sustained therapeutic effects. The eye, with its delicate structure and specific needs, presents unique challenges for drug delivery and tissue regeneration. This review explores the transformative potential of adhesive hydrogels in addressing these challenges across a range of ocular conditions, including corneal injuries, cataracts, glaucoma, vitreoretinal disorders, and ocular trauma.

Marchiafava-Bignami disease (MBD) is a rare condition characterized by demyelination and necrosis of the corpus callosum, most commonly associated with chronic alcohol consumption. However, it can also occur in non-alcoholic patients and may present secondary to other underlying conditions. We report a case of a 52-year-old male with no history of alcohol use or significant comorbidities, presenting with impaired consciousness and severe malnutrition.

We report a 37-year-old male patient who had nonbilious vomiting, no passage of flatus, and recurring abdominal pain. This patient had de novo intestinal myeloid sarcoma (MS), a rare and chameleonic presentation of acute leukemia of myeloid origin. The initial diagnostic evaluation suggested Koch's abdomen, and surgical excision of the bowel was performed with a clinical suspicion of Koch's or lymphoma.

Introduction: Retrograde ejaculation (RE) consists of the reflux backwards, towards the bladder, of the ejaculate, during the emission phase of ejaculation, causing a total or partial absence of sperm emission, with the consequent diversion of semen into the bladder during the emission phase of ejaculation. Evaluating the ejaculate may not be sufficient for identifying RE in some patients. Hence, the management of infertility may involve the use of invasive methods such as epididymal fluid retrieval or testicular biopsy.

Introduction: The aim of this study is to examine the physiological effects of emodin on intestinal microorganisms and the liver in the BALb/c mice.

Method And Results: Following an 8-week administration of emodin at doses of 25, 50, and 100 mg/kg/day,pathological analyses revealed that emodin significantly reduced the colon length, induced colonic crypt inflammation,diminished the colonic mucus layer,and decreased the fluorescence intensity of colonic tight junction proteins ZO-1 and Occludin. Concurrently, 16S rDNA gene sequencing corroborated that emodin altered the diversity and composition of the intestinal microbiota by increasing the to ratio.

The clinical efficacy of isocitrate dehydrogenase (IDH) inhibitors in the treatment of patients with grade 2 IDH-mutant (mIDH) gliomas is a significant therapeutic advancement in neuro-oncology. It expands treatment options beyond traditional radiation therapy and cytotoxic chemotherapy, which may lead to significant long-term neurotoxic effects while extending patient survival. The INDIGO study demonstrated that vorasidenib, a pan-mIDH inhibitor, improved progression-free survival for patients with grade 2 mIDH gliomas following surgical resection or biopsy compared to placebo and was well tolerated.

Advances of Stimuli-Responsive Amphiphilic Copolymer Micelles in Tumor Therapy.

Int J Nanomedicine

January 2025

Department of pharmacy, west china hospital,  Sichuan University, Chengdu, 610041, People's Republic of China.

Amphiphilic copolymers are composed of both hydrophilic and hydrophobic chains, which can self-assemble into polymeric micelles in aqueous solution via the hydrophilic/hydrophobic interactions. Due to their unique properties, polymeric micelles have been widely used as drug carriers. Poorly soluble drugs can be covalently attached to polymer chains or non-covalently incorporated in the micelles, with improved pharmacokinetic profiles and enhanced efficacy.
