Egg multivesicular bodies elicit an LC3-associated phagocytosis-like pathway to degrade paternal mitochondria after fertilization.

Mitochondria are maternally inherited, but the mechanisms underlying paternal mitochondrial elimination after fertilization are far less clear. Using Drosophila, we show that special egg-derived multivesicular body vesicles promote paternal mitochondrial elimination by activating an LC3-associated phagocytosis-like pathway, a cellular defense pathway commonly employed against invading microbes. Upon fertilization, these egg-derived vesicles form extended vesicular sheaths around the sperm flagellum, promoting degradation of the sperm mitochondrial derivative and plasma membrane.

Structured RhoGEF recruitment drives myosin II organization on large exocytic vesicles.

The Rho family of GTPases plays a crucial role in cellular mechanics by regulating actomyosin contractility through the parallel induction of actin and myosin assembly and function. Using exocytosis of large vesicles in the Drosophila larval salivary gland as a model, we followed the spatiotemporal regulation of Rho1, which in turn creates distinct organization patterns of actin and myosin. After vesicle fusion, low levels of activated Rho1 reach the vesicle membrane and drive actin nucleation in an uneven, spread-out pattern.

MACCABI-RED, community emergency care at the press of a button: a descriptive study.

Background: Maccabi-RED is a new service developed in Israel that allows primary care staff to direct urgent cases to specialists in the community for evaluation in their local clinics on the same day as an alternative to an emergency department (ED) visit. A primary care physician or a nurse can activate the service, and all nearby specialists receive "a call" and can decide if they are willing to accept it, thus allowing the patient to avoid an unnecessary visit to the ED.

Aim: To quantify and characterize the medical care provided by this service in a large national healthcare system.

Harnessing innovation to help meet the needs of elders: field testing an electronic tool to streamline geriatric assessments across healthcare settings.

Background: As populations age globally, effectively managing geriatric health poses challenges for primary care. Comprehensive geriatric assessments (CGAs) aim to address these challenges through multidisciplinary screening and coordinated care planning. However, most CGA tools and workflows have not been optimised for routine primary care delivery.

Human Papilloma Virus Typing as a Triage Tool for Women with Postcoital Bleeding: A Retrospective Cohort Study.

To investigate the performance of human papilloma virus (HPV) typing as a triage tool in the management of patients with postcoital bleeding (PCB). All patients referred for colposcopy at a cervical pathology clinic of a nationwide health insurance organization, due to PCB and had a preceding high-risk HPV (hrHPV) test between 2018 and 2020, were retrospectively located. Demographic and pathologic data were collected from electronic medical files.
