Article Synopsis
  • The review focuses on the diagnosis, classification, and management of lateral compression fragility fractures of the pelvis, emphasizing the shift toward early surgery treatment for better outcomes.
  • Lateral compression pelvic fractures are common in older adults, typically resulting from low-impact falls, and can lead to serious complications like loss of independence and prolonged hospital stays.
  • Current practices often recommend nonsurgical treatment for these fractures, but there is insufficient evidence to support this approach, indicating a need for more research on early surgical intervention.

Purpose: The recent SENZA-PDN study showed that high-frequency (10kHz) spinal cord stimulation (SCS) provided significant, durable pain relief for individuals with painful diabetic neuropathy (PDN), along with secondary benefits, including improved sleep quality and HRQoL. Given that metabolic factors and chronic neuropathic pain are related, we evaluated potential secondary effects of 10kHz SCS on hemoglobin A1c (HbA1c) and weight in SENZA-PDN participants with type 2 diabetes (T2D).

Patients And Methods: This analysis included 144 participants with T2D and lower limb pain due to PDN who received 10kHz SCS during the SENZA-PDN study.

Article Synopsis
  • Congenital heart defects (CHDs) are prevalent in children with Down syndrome, affecting 40-50% of this population.
  • A study sequenced the genomes of a diverse group of children with Down syndrome, both with CHD and with normal hearts, to explore the genetic factors associated with these heart defects.
  • While no specific genetic variants reached significant levels, several loci were identified with suggestive links to risk factors for different types of CHD, providing insights into potential genetic contributors to these defects.

Electronic address:

Polyphenols have been well-established to exert sedative-hypnotic effects in psychopharmacology. Lime (Citrus aurantifolia) peel is rich in biologically active polyphenols; however, the effects of lime peel extract on sleep have not yet been demonstrated. A comparison was conducted in mice, between the sleep-promoting effects of a standardized lime peel supplement (SLPS) and a well-known hypnotic drug, zolpidem, and its hypnotic mechanism was investigated using in vivo and in vitro assays.

Cilia defects upon loss of WDR4 are linked to proteasomal hyperactivity and ubiquitin shortage.

Cell Death Dis

September 2024

Department of Experimental and Clinical Pharmacology and Pharmacogenomics, Section of Pharmacogenomics, Eberhard-Karls-University Tübingen, 72074, Tübingen, Germany.

The WD repeat-containing protein 4 (WDR4) has repeatedly been associated with primary microcephaly, a condition of impaired brain and skull growth. Often, faulty centrosomes cause microcephaly, yet aberrant cilia may also be involved. Here, we show using a combination of approaches in human fibroblasts, zebrafish embryos and patient-derived cells that WDR4 facilitates cilium formation.

Introduction: Lesbian, gay, bisexual, transgender, queer, and all sexually and gender diverse (LGBTQ+) people experience discrimination across many contexts, including healthcare environments. While some research has shown transgender people and non-binary people often endure higher rates of marginalization than cisgender, sexually diverse people, past data are limited.

Methods: A sample of LGBTQ+ people ( = 173) in the United States completed an anonymous, online, self-reported survey, which included the Consumer Assessment of Healthcare Providers and Systems and healthcare experience questions.

Article Synopsis
  • - Diabetes affects 537 million people globally, and 34% are at risk of developing foot ulcers, prompting the need for standard outcomes in treatment studies.
  • - A Core Outcome Set (COS) was created through a structured process involving systematic reviews, patient interviews, and a two-round Delphi survey with input from patients and experts.
  • - The COS includes 8 critical outcomes, such as wound healing and quality of life, which will help improve the consistency of research assessing diabetes-related foot ulcer treatments.

Purpose: Spinal stereotactic body radiation therapy (SBRT) has become the standard of care in management of patients with limited sites of metastatic disease, radioresistant histologies, painful vertebral metastases with long life expectancy and cases of reirradiation. Our case-based guidelines aim to assist radiation oncologists in the appropriate utilization of SBRT for common, yet challenging, cases of spinal metastases.

Methods And Materials: Cases were selected to include scenarios of large volume sacral disease with nerve entrapment, medically inoperable disease abutting the thecal sac, and local failure after prior SBRT.

  • Alternative lengthening of telomeres (ALT) is found in sarcomas, and this study investigates its frequency in Ewing's family sarcoma (EFS), rhabdomyosarcoma (RMS), and osteosarcoma (OS) using a specific PCR assay to detect telomeric DNA C-circles.
  • After analyzing DNA from 273 primary tumor samples, results showed ALT in 0% of EFS, 2.7% of RMS, and 71% of OS, indicating a significant variability in ALT presence among these cancers.
  • The findings suggest that the C-circle assay (CCA) is an effective method for identifying ALT in sarcomas and could serve as a valuable tool

Oral Fenbendazole for Cancer Therapy in Humans and Animals.

Anticancer Res

September 2024

Nimni-Cordoba Tissue Engineering and Drug Discovery Lab, Department of Surgery, Keck School of Medicine of University of Southern California, Los Angeles, CA, U.S.A.

Fenbendazole is a benzimidazole anthelmintic agent commonly used to treat animal parasitic infections. In humans, other benzimidazoles, such as mebendazole and albendazole, are used as antiparasitic agents. Since fenbendazole is not currently approved by the FDA or EMA, its pharmacokinetics and safety in humans have yet to be well-documented in medical literature.

Zeenat Qureshi Stroke Institute and Department of Neurology, University of Missouri, Columbia, MO, USA. Electronic address:

Background And Purpose: Post thrombolytic intracerebral hemorrhage (ICH) is associated with higher rate of death or disability in acute ischemic stroke patients. We investigated the relationship between post thrombolytic ICH volume and change in volume and death or disability at 90 days in acute ischemic stroke patients.

Methods: We analyzed 110 patents recruited in the Safety Evaluation of 3K3A-APC in Ischemic Stroke (RHAPSODY) trial who received intravenous tissue plasminogen activator (tPA) followed by mechanical thrombectomy (if indicated) and 3K3A-APC or placebo.

Tumor-educated platelets (TEPs) are a potential method of liquid biopsy for the diagnosis and monitoring of cancer. However, the mechanism underlying tumor education of platelets is not known, and transcripts associated with TEPs are often not tumor-associated transcripts. We demonstrated that direct tumor transfer of transcripts to circulating platelets is an unlikely source of the TEP signal.

  • The integration of artificial intelligence (AI) in healthcare, particularly in radiology, has led to improved efficiency, diagnostic accuracy, and patient care, while also presenting new challenges.
  • Despite the potential benefits of AI in diagnosing conditions like intracranial hemorrhage and spinal fractures, limitations such as data imbalances and algorithm transparency hinder its widespread implementation.
  • Addressing these limitations is crucial for maximizing AI's advantages in emergency radiology and ensuring patient safety.

Strategies for optimal management of pediatric acute agitation in emergency settings.

J Am Coll Emerg Physicians Open

August 2024

David Geffen School of Medicine at UCLA The Lundquist Institute for Biomedical Innovation at Harbor UCLA Department of Emergency Medicine, Harbor UCLA Medical Center Torrance California USA.

Acute agitation in youth is a challenging presentation to the emergency department. In many cases, however, youth can be behaviorally de-escalated using a combination of environmental modification and verbal de-escalation. In cases where additional strategies such as pharmacologic de-escalation or physical restraint are needed, using the least restrictive means possible, including the youth in the decision-making process, and providing options are important.
