Cancer is a major global concern. Despite considerable advancements in cancer therapy and control, there are still large gaps and requirements for development. In recent years, various naturally occurring anticancer drugs have been derived from natural resources, such as alkaloids, glycosides, terpenes, terpenoids, flavones, and polyphenols.

Alzheimer's disease is the neurodegenerative disorder responsible for approximately 60% to 70% of all cases of dementia and is expected to affect 152 million by 2050. Recently, anti-amyloid therapies have been developed and approved by the Food and Drug Administration as disease-modifying treatments given as infusions every 2 to 5 weeks for Alzheimer's disease. Although this is an important milestone in mitigating Alzheimer's disease progression, it is critical for emergency medicine clinicians to understand what anti-amyloid therapies are and how they work to recognize, treat, and mitigate their adverse effects.

Background: Low blood absolute lymphocyte count (ALC) may predict severe COVID-19 outcomes. Knowledge gaps remain regarding the relationship of ALC trajectory with clinical outcomes and factors associated with lymphopenia.

Methods: Our post hoc analysis of the Therapeutics for Inpatients with COVID-19 platform trial utilized proportional hazards models to assess relationships between Day (D) 0 lymphopenia (ALC < 0.

Over the past decade, researchers translating anthropological theories for clinical use have debated how practitioners should assess cultural factors, social structures, and social determinants of health with patients. Advocates of structural competency have suggested that clinical cultural competency programs demonstrate limited effects on health outcomes because of the static understanding of culture employed. They recommend that cultural factors be reformulated with an emphasis on social structures.

Article Synopsis
  • The study investigates risk factors for proliferative vitreoretinopathy (PVR), a common complication after retinal detachment surgery.
  • A large patient database was analyzed, identifying systemic (like age, gender, and smoking) and ocular (such as trauma and previous eye conditions) factors that correlate with increased PVR risk.
  • The findings emphasize the importance of considering these risk factors in surgical planning and treatment to prevent PVR in patients with retinal detachment.

Background: Mentoring helps in the personal and professional development of mentees and helps them develop self-confidence in their work. Final-year undergraduate medical students face many challenges but they also have to gain the confidence to start working independently and plan their careers in the near future. In the coronavirus disease scenario, many of these challenges were amplified, and final-year students were in greater need of mentoring.

Pancreatic ductal adenocarcinoma (PDAC) remains one of the deadliest solid cancers; thus, identifying more effective therapies is a major unmet need. In this study, we characterized the super enhancer (SE) landscape of human PDAC to identify drivers of the disease that might be targetable. This analysis revealed MICAL2 as a super enhancer-associated gene in human PDAC, which encodes the flavin monooxygenase MICAL2 that induces actin depolymerization and indirectly promotes SRF transcription by modulating the availability of serum response factor coactivators myocardin-related transcription factors (MRTF-A and MRTF-B).

Introduction: Empathy is a fundamental element of high-quality healthcare, though it has been shown to be in decline among medical students and residents. Appeals have therefore been made for the development of evidence-based empathy-enhancing experiential learning and training models. Bringing Art to Life (BATL) is a service-learning program designed within experiential learning pedagogy for psychology and pre-healthcare students.

Background: Distal radius fractures (DRFs) are some of the most common injuries suffered by the elderly; however, there are varied opinions on management. As there is limited research on patient factors affecting functional outcomes in conservatively managed patients with DRFs, this study aimed to find predictive factors for functional outcomes in such patients.

Methods: Patients with DRFs satisfying the inclusion criteria were managed with closed reduction and slab followed by cast application.

Background: Tumor cells within the tumor microenvironment (TME) release exosomes that influence macrophage phenotypes, either pro-tumorigenic or anti-tumorigenic. This mechanism, especially in head and neck squamous cell carcinoma (HNSCC), remains poorly understood. This study investigates the role of HNSCC exosomes in macrophage polarization.

Nanocellulose is the renewable biopolymer produced in nature by different bacteria. The widespread use of nanocellulose in industrial processes increases the demand for this valuable biomaterial. To overcome the high cost of producing nanocellulose using the Hestrin-Schramm medium, alternative agricultural waste has been studied as a potential low-cost supply.

Article Synopsis
  • The study examines how diet patterns relate to the risk of intracranial atherosclerosis (ICAD) in people with existing hypertension or a history of myocardial infarction.
  • A total of 676 older adults were autopsied, and none showed a direct link between overall diet and atherosclerosis, though hypertension was found to increase the risk of ICAD.
  • Notably, individuals with a healthier diet (like the MIND or Mediterranean diet) had lower chances of severe ICAD, especially among those with a history of myocardial infarction.

The preferred treatment for medically inoperable early-stage endometrial cancer (EC) is definitive radiation therapy (RT), either in the form of brachytherapy (BT) alone or in combination with external beam radiotherapy (EBRT). This case report details a modified brachytherapy approach for a 59-year-old female patient who was known to have multiple comorbidities, poor performance status, and progressive slowness in activities of daily living. She presented with a complaint of post-menopausal bleeding per vaginum, for which she underwent investigations and was diagnosed with a case of endometrial adenocarcinoma, International Federation of Gynecology and Obstetrics (FIGO) stage IA and grade I.

Histiocytic and dendritic cell neoplasms, especially histiocytic sarcoma, can show morphologic and phenotypic overlap with immature monocytic neoplasms. IRF8 immunohistochemical staining has been demonstrated to be useful in identifying monoblasts, but it has not been extensively studied in histiocytic and dendritic cell neoplasms. IRF8 immunohistochemistry was performed on cases of histiocytic sarcoma (HS, n=6), Langerhans cell histiocytosis (LCH, n=25), Rosai Dorfman disease (RDD, n=17), follicular dendritic cell sarcoma (FDCS, n=3), and Erdheim Chester disease (ECD, n=5), along with a control group that included a subset of myeloid neoplasms with monocytic differentiation.

Article Synopsis
  • In recent years, several states have passed laws granting advanced practice providers (APPs) more independence, including Montana's recent House Bill 313 allowing physician assistants to practice independently in primary care.
  • Research indicates that allowing nonphysicians to practice independently can lead to poorer patient outcomes and higher healthcare costs.
  • The commentary warns of potential negative consequences from expanding the scope of practice for APPs, particularly in states like Montana, where such legislation has been enacted.

  • Non-responsive celiac disease (NRCD) occurs when patients experience ongoing symptoms despite following a gluten-free diet for 6-12 months, with a prevalence found to be about 22% in a systematic review of studies.
  • The analysis identified inadvertent gluten exposure as the leading cause of NRCD, affecting one-third of the patients, followed by functional gastrointestinal disorders like irritable bowel syndrome.
  • The findings highlight the need for better adherence to gluten-free diets and the development of new treatments to address symptoms persisting from unintentional gluten intake.

To compare the modeled costs of the Protocol AC bevacizumab-first treatment protocol (with a switch to aflibercept for sub-responders) with real-world costs for treatment-naïve patients with diabetic macular edema (DME) over a 2-year period. Published data from the Diabetic Retinopathy Clinical Research Network (DRCR) Protocol AC bevacizumab-first arm (154 eyes) were used to model 2-year treatment costs. Real-world costs were modeled using data from the Vestrum Health electronic medical records database from a 2016 to 2018 cohort of treatment-naïve eyes with DME (n = 1062) treated with antivascular endothelial growth factor monotherapy.
