Outcomes of Allogeneic Hematopoietic Stem Cell Transplantation in Patients Aged 70 Years and Older: A Systematic Review and Meta-analysis.

Background: Allogeneic hematopoietic cell transplantation (allo-HCT) is a potential cure for many hematological malignancies. Historically, older adults were not considered eligible for allo-HCT due to increased toxicity and mortality concerns. This systematic review and meta-analysis aim to explore the outcomes of allo-HCT in patients aged 70 years or older.

Radiolabeled HER2-targeted molecular probes in breast cancer imaging: current knowledge and future prospective.

Breast cancer is the most frequent non-dermatologic malignancy in women. Breast cancer is characterized by the expression of the human epidermal growth factor receptor type 2 (HER2), and the presence or lack of estrogen receptor (ER) and progesterone receptor (PR) expression. HER2 overexpression is reported in about 20 to 25% of breast cancer patients, which is usually linked to cancer progression, metastases, and poor survival.

The assessment of the perceived stress and the quality of life in the patients with myasthenia gravis: The mediating role of the psychological capital and social support.

Stress has been known as a risk factor for the onset and modification of autoimmune disorders such as myasthenia gravis (MG). However, the patients can control their stress and improve their quality of life (QOL) using some factors such as psychological and social support. Psychological capital and social support play a key role in decreasing stress and improving QOL in the patients with MG.

Explainable artificial intelligence for stroke prediction through comparison of deep learning and machine learning models.

Failure to predict stroke promptly may lead to delayed treatment, causing severe consequences like permanent neurological damage or death. Early detection using deep learning (DL) and machine learning (ML) models can enhance patient outcomes and mitigate the long-term effects of strokes. The aim of this study is to compare these models, exploring their efficacy in predicting stroke.

Plasma exchange as a rescue therapy for treatment-resistant thyroid storm with concurrent heart failure: a literature review based on a case report.

Introduction: Thyroid storm or severe hyperthyroidism can present with various signs and symptoms. They are mostly controlled by general treatment, such as anti-thyroid drugs and other medications to control clinical features. However, in rare cases, they are more severe, and they only respond to more aggressive treatments, such as plasmapheresis and total thyroidectomy.

Immune checkpoints and ncRNAs: pioneering immunotherapy approaches for hematological malignancies.

Hematological malignancies are typically treated with chemotherapy and radiotherapy as the first-line conventional therapies. However, non-coding RNAs (ncRNAs) are a rapidly expanding field of study in cancer biology that influences the growth, differentiation, and proliferation of tumors by targeting immunological checkpoints. This study reviews the results of studies (from 2012 to 2024) that consider the immune checkpoints and ncRNAs in relation to hematological malignancies receiving immunotherapy.

Asymptomatic multifocal avascular necrosis, a commonly overlooked finding in patients with systemic lupus erythematosus.

Background: In patients with Systemic lupus erythematosus (SLE), osteonecrosis of various joints is a debilitating complication associated with the disease and its treatment, in which a considerable proportion of osteonecrosis may be asymptomatic. Recognizing the crucial role of early and timely detection, as well as appropriate management of asymptomatic osteonecrosis, in preventing joint destruction, we conducted a study to evaluate the prevalence of asymptomatic osteonecrosis in SLE patients who have already been diagnosed with symptomatic osteonecrosis. Additionally, we aimed to examine the relationship between proposed risk factors of osteonecrosis and the development of asymptomatic osteonecrosis.

Hemifacial spasm (HFS) is an important condition for plastic surgeons to understand, as it significantly affects patients' quality of life and can complicate aesthetic and reconstructive procedures. Magnetic resonance imaging (MRI) has become vital in diagnosing HFS, assessing neurovascular relationships, and planning treatment. Transverse MRI scans often show an upward displacement of the inferior pons at the facial nerve attachment point, signaling neurovascular compression (NVC) in HFS.
