First Experience with the NPseal®: A Novel Mechanically Powered Negative Pressure Dressing Applied to Colorectal Surgery Wounds.

Background: The use of prophylactic closed-incisional negative pressure wound therapy after colorectal procedures has been shown to reduce postoperative wound complications and surgical site infection. We present our experience with a novel, closed-incision, mechanically powered negative pressure (MP-NPD) dressing after colorectal procedures.

Methods: This was a prospective, single-center, single-arm observational study assessing patient reported and wound healing outcomes of colorectal surgical incisions dressed with a MP-NPD.

Correction: Predicting physician departure with machine learning on EHR use patterns: A longitudinal cohort from a large multi-specialty ambulatory practice.

Atypical Presentation of a Ruptured Anterior Communicating Artery Aneurysm With Subdural, Intraparenchymal, and Subarachnoid Hemorrhage.

Anterior communicating artery (ACom) aneurysm, one of the most frequent types of intracranial aneurysm rupture, usually results in a subarachnoid hemorrhage (SAH) with intraventricular hemorrhage. We describe a case of an ACom aneurysm rupture with subarachnoid, intraparenchymal, and subdural hemorrhages (SDH) with midline shift in a 55-year-old woman. Decompressive craniectomy was performed to evacuate the SDH with subsequent microsurgical clipping of the aneurysm.

Mapping the ionosphere with millions of phones.

The ionosphere is a layer of weakly ionized plasma bathed in Earth's geomagnetic field extending about 50-1,500 kilometres above Earth. The ionospheric total electron content varies in response to Earth's space environment, interfering with Global Satellite Navigation System (GNSS) signals, resulting in one of the largest sources of error for position, navigation and timing services. Networks of high-quality ground-based GNSS stations provide maps of ionospheric total electron content to correct these errors, but large spatiotemporal gaps in data from these stations mean that these maps may contain errors.

Correlates of improved outcomes in patients with COVID-19 treated in US emergency departments.

Background: The COVID-19 pandemic was managed in part by the rapid development of vaccines, diagnostics, and therapeutics including antiviral agents and advances in emergency airway and ventilatory management. The impact of these therapeutic advances on clinically pertinent metrics of emergency care have not been well-studied.

Methods: We abstracted data from emergency department (ED) visits made to 21 US health systems during the first two years of the pandemic, from February 1, 2020 to January 31, 2022.

Patient Compliance With Bowel Preparation for Elective Colorectal Surgery.

Introduction: Studies show that mechanical bowel preparation (MBP) plus oral antibiotics (OAs) is associated with decreased rates of postoperative complications after elective colorectal surgery. However, there is a lack of literature regarding patient compliance with bowel preparation (BP).

Materials And Methods: Patients undergoing elective colorectal surgeryfrom April 2020 to March 2022 at a tertiary care academic hospital (TCAH) and safety net hospital (SNH) were administered a BP compliance survey.

Stereotactic Radiosurgery With Versus Without Neoadjuvant Endovascular Embolization for Brain Arteriovenous Malformations With Associated Intracranial Aneurysms.

Background And Objectives: Stereotactic radiosurgery (SRS) with neoadjuvant embolization is a treatment strategy for brain arteriovenous malformations (AVMs), especially for those with large nidal volume or concomitant aneurysms. The aim of this study was to assess the effects of pre-SRS embolization in AVMs with an associated intracranial aneurysm (IA).

Methods: The International Radiosurgery Research Foundation AVM database from 1987 to 2018 was retrospectively reviewed.

Engaging Oncology and Occupational Medicine to Inform Design of a Total Worker Health® Intervention to Address Employment, Financial, and Well-being Outcomes in Cancer Survivors.

Objectives: Few Total Worker Health ® studies and fewer interventions examine well-being in the work context of cancer survivorship. We investigated the possibility of occupation and oncology professionals working together to address employed survivors' work-associated needs.

Methods: We employed a community-based participatory research approach to examine the educational, contextual, and workflow needs of oncology care team members to inform intervention design.

Hospital outcomes for young adults with COVID-19.

Background: Older adults are at higher risk of severe outcomes from COVID-19 with comorbidities increasing such risk. Much less is known about the outcomes of young adults with COVID-19 despite their having had high infection rates.

Objectives: Our objective was to determine outcomes of hospitalized young adults with COVID-19 infection including rates of oxygen use, mortality, ICU admission, intubation, duration of hospitalization, and factors associated with adverse outcomes.

Engineering programmable material-to-cell pathways via synthetic notch receptors to spatially control differentiation in multicellular constructs.

Synthetic Notch (synNotch) receptors are genetically encoded, modular synthetic receptors that enable mammalian cells to detect environmental signals and respond by activating user-prescribed transcriptional programs. Although some materials have been modified to present synNotch ligands with coarse spatial control, applications in tissue engineering generally require extracellular matrix (ECM)-derived scaffolds and/or finer spatial positioning of multiple ligands. Thus, we develop here a suite of materials that activate synNotch receptors for generalizable engineering of material-to-cell signaling.

Antigen-specific age-related memory CD8 T cells induce and track Alzheimer's-like neurodegeneration.

Cerebral (Aβ) plaque and (pTau) tangle deposition are hallmarks of Alzheimer's disease (AD), yet are insufficient to confer complete AD-like neurodegeneration experimentally. Factors acting upstream of Aβ/pTau in AD remain unknown, but their identification could enable earlier diagnosis and more effective treatments. T cell abnormalities are emerging AD hallmarks, and CD8 T cells were recently found to mediate neurodegeneration downstream of tangle deposition in hereditary neurodegeneration models.

Partial coil embolization before surgical clipping of ruptured intracranial aneurysms.

Objective: Intraoperative rupture (IOR) is the most common adverse event encountered during surgical clip obliteration of ruptured intracranial aneurysms. Besides increasing surgeon experience and early proximal control, no methods exist to decrease IOR risk. Thus, our objective was to assess if partial endovascular coil embolization to protect the aneurysm before clipping decreases IOR.

The prognostic effect of mechanical, ultrastructural, and ECM signatures in glioblastoma core and rim.

Glioblastoma (GBM) is a highly invasive, aggressive brain cancer that carries a median survival of 15 months and is resistant to standard therapeutics. Recent studies have demonstrated that intratumoral heterogeneity plays a critical role in promoting resistance by mediating tumor adaptation through microenvironmental cues. GBM can be separated into two distinct regions-a core and a rim, which are thought to drive specific aspects of tumor evolution.

Addressing Substance Use in the Adolescent Transplant Population.

Adolescence is a unique period of physical and psychosocial changes as youth transition, over many years, to adulthood. The psychosocial changes that accompany adolescence include emotional separation from parents, greater influence of peer groups, an interest in self-identification and autonomy, and increased risk-taking behaviors. Substance use is a common form of risk-taking behavior in the adolescent developmental stage.

The ENCODE mouse postnatal developmental time course identifies regulatory programs of cell types and cell states.

Postnatal genomic regulation significantly influences tissue and organ maturation but is under-studied relative to existing genomic catalogs of adult tissues or prenatal development in mouse. The ENCODE4 consortium generated the first comprehensive single-nucleus resource of postnatal regulatory events across a diverse set of mouse tissues. The collection spans seven postnatal time points, mirroring human development from childhood to adulthood, and encompasses five core tissues.

Longitudinal evolution of the HIV effective reproduction number following sequential expansion of treatment as prevention and pre-exposure prophylaxis in British Columbia, Canada: a population-level programme evaluation.

Background: Treatment as prevention and pre-exposure prophylaxis (PrEP) are key strategies in the control of HIV/AIDS. We aimed to characterise the longitudinal effects of antiretroviral therapy (ART), followed by treatment as prevention and the addition of PrEP, on the HIV effective reproduction number (R) in British Columbia, Canada.

Methods: This population-level programme evaluation used data from the Drug Treatment Program of the British Columbia Centre for Excellence in HIV/AIDS (Vancouver, British Columbia, Canada).

Pathologic Outcomes of Short-Course and Long-Course Radiotherapy for Locally Advanced Rectal Cancers Treated With Total Neoadjuvant Therapy.

Introduction: Total neoadjuvant therapy (TNT) for patients with locally advanced rectal cancer (LARC) is now the standard of care. Randomized trials suggest the use of short-course radiotherapy (SCRT) and long-course radiotherapy (LCRT) are oncologically equivalent.

Objective: To describe pathologic outcomes after surgical resections of patients receiving SCRT versus LCRT as part of TNT for LARC.
