The trochlea for the intermediate tendon of the digastric muscle: a review.

This review explores the novel perspective that the intermediate tendon of the digastric muscle may function as an anatomical trochlear pulley system within the human body, challenging the traditional understanding of trochlear systems. While widely recognized trochlear units include structures like the medial part of the humerus and the superior oblique muscle of the orbit, the review focuses on the unique anatomical arrangement of the intermediate tendon of the digastric muscle in connection with the anterior and posterior bellies of the digastric muscles. Despite current debates within the anatomical community about labeling the digastric muscles as having a trochlea, this paper delves into the scientific definition of a trochlear pulley system, presenting the intermediate tendon of the digastric muscle as a potential trochlea.

However, the traditional sub-internship structure, with multiple learners at varied levels, poses obstacles to providing the clinical exposure, learning environment, and direct observation and feedback necessary to develop essential skills.

Aim: Investigate the educational experience of learners on a coaching-centered sub-internship (CCSI) on a resident uncovered ward service.

Variable surface antigen expression, virulence, and persistent infection by malaria parasites.

SUMMARYThe human malaria parasite is known for its ability to maintain lengthy infections that can extend for over a year. This property is derived from the parasite's capacity to continuously alter the antigens expressed on the surface of the infected red blood cell, thereby avoiding antibody recognition and immune destruction. The primary target of the immune system is an antigen called PfEMP1 that serves as a cell surface receptor and enables infected cells to adhere to the vascular endothelium and thus avoid filtration by the spleen.

Multicentre study conducted across centres in the USA, Europe and Australia to assess the safety and effectiveness of a bilateral hypoglossal nerve stimulation system for the treatment of obstructive sleep apnoea in adults: a protocol for a pivotal, multicentre, open-label, single-arm study.

Introduction: Obstructive sleep apnoea (OSA) is characterised by blood oxygen desaturations and sleep disruptions manifesting undesirable consequences. Existing treatments including oral appliances, positive airway pressure (PAP) therapy and surgically altering the anatomy of the pharynx have drawbacks including poor long-term adherence or often involving irreversible, invasive procedures. Bilateral hypoglossal nerve stimulation (HNS) is a new treatment for managing OSA, and this study is intended to determine whether an HNS system is a safe and effective treatment option for adults with OSA.

Harnessing the tumor microenvironment: targeted cancer therapies through modulation of epithelial-mesenchymal transition.

The tumor microenvironment (TME) is integral to cancer progression, impacting metastasis and treatment response. It consists of diverse cell types, extracellular matrix components, and signaling molecules that interact to promote tumor growth and therapeutic resistance. Elucidating the intricate interactions between cancer cells and the TME is crucial in understanding cancer progression and therapeutic challenges.

Loss of Kmt2c or Kmt2d primes urothelium for tumorigenesis and redistributes KMT2A-menin to bivalent promoters.

Members of the KMT2C/D-KDM6A complex are recurrently mutated in urothelial carcinoma and in histologically normal urothelium. Here, using genetically engineered mouse models, we demonstrate that Kmt2c/d knockout in the urothelium led to impaired differentiation, augmented responses to growth and inflammatory stimuli and sensitization to oncogenic transformation by carcinogen and oncogenes. Mechanistically, KMT2D localized to active enhancers and CpG-poor promoters that preferentially regulate the urothelial lineage program and Kmt2c/d knockout led to diminished H3K4me1, H3K27ac and nascent RNA transcription at these sites, which leads to impaired differentiation.

Small intestinal bacterial overgrowth: from malabsorption to misinterpretation.

Small intestinal bacterial overgrowth (SIBO) was originally described as a cause of maldigestion and malabsorption in situations where disruptions of intestinal anatomy or physiology favored the proliferation of bacteria normally confined to the colon. In this context, the pathogenesis of symptoms resulting from SIBO was well described. More recently, the concept of SIBO was extended to explain symptoms such as bloating, altered bowel habit and discomfort among individuals with irritable bowel syndrome and since then a whole host of gastrointestinal and extragastrointestinal disorders have been attributed to SIBO.

2024 HRS perspective on advancing workflows for CIED remote monitoring.

Cardiac implantable electronic devices (CIEDs) generate substantial data, often stored in image or PDF formats. Remote monitoring, now an integral component of patient care, places considerable administrative burdens on clinicians and staff, in large part due to the challenge of integrating these data seamlessly into electronic health records. Since 2006, the Heart Rhythm Society, in collaboration with the CIED industry, has led an initiative to establish a unified standard nomenclature.

Vascular Access for Home Hemodialysis: A Perspective on Tunneled Central Venous Catheters at Home.

Expansion of home hemodialysis (HHD) provides an opportunity to improve clinical outcomes, reduce cost of care, and address the staffing challenges currently faced in caring for patients with kidney failure on replacement therapy. To increase HHD expansion, current practices and barriers to home dialysis must be examined and addressed. One such barrier is vascular access for HHD; although tunneled hemodialysis central venous catheters (CVCs) have been used for decades, physicians still hesitate to send patients home without a mature, functional arteriovenous access.

Combining a WT1 Vaccine (Galinpepimut-S) With Checkpoint Inhibition (Nivolumab) in Patients With WT1-Expressing Diffuse Pleural Mesothelioma: A Phase 1 Study.

Introduction: WT1 often presents on the surface of diffuse pleural mesotheliomas (DPMs) and is an ideal therapeutic target. Galinpepimut-S (GPS), a tetravalent, non-human leukocyte antigen-restricted, heteroclitic WT1-specific peptide vaccine was safe and effective in early phase clinical trials and upregulates T-cell suppressive programmed death-ligand 1 in the tumor microenvironment of other malignancies. A randomized phase 2 study of adjuvant GPS in patients with DPM trended toward improved median overall survival.

Radiosurgery for Intracranial Meningiomas: A Review of Anatomical Challenges and an Update on the Evidence.

Radiation has been used to treat meningiomas since the mid-1970s. Traditionally, radiation was reserved for patients unfit for major surgery or those with surgically inaccessible tumors. With an increased quantity and quality of imaging, and an aging population, there has been a rise in incidentally diagnosed meningiomas with smaller tumors at diagnosis time.

Engineered Mycobacterium tuberculosis triple-kill-switch strain provides controlled tuberculosis infection in animal models.

Human challenge experiments could accelerate tuberculosis vaccine development. This requires a safe Mycobacterium tuberculosis (Mtb) strain that can both replicate in the host and be reliably cleared. Here we genetically engineered Mtb strains encoding up to three kill switches: two mycobacteriophage lysin operons negatively regulated by tetracycline and a degron domain-NadE fusion, which induces ClpC1-dependent degradation of the essential enzyme NadE, negatively regulated by trimethoprim.

Improving the Robustness of Deep-Learning Models in Predicting Hematoma Expansion from Admission Head CT.

Background And Purpose: Robustness against input data perturbations is essential for deploying deep-learning models in clinical practice. Adversarial attacks involve subtle, voxel-level manipulations of scans to increase deep-learning models' prediction errors. Testing deep-learning model performance on examples of adversarial images provides a measure of robustness, and including adversarial images in the training set can improve the model's robustness.
