Who dies from venous thromboembolism after hospitalisation for other reasons in England?: a national retrospective cohort study.

Objectives: Venous thromboembolism (VTE) is a major cause of morbidity and mortality globally, with hospital-associated thrombosis (HAT) accounting for at least half of VTE. We set out to understand more about deaths from HAT in England, to focus improvement efforts where they are needed most.

Design: A retrospective cohort combining death certification and hospital activity data to identify people with an inpatient or day case hospitalisation where no VTE diagnosis was recorded, and who died from VTE in a hospital or within 90 days of discharge, between April 2017 and March 2020.

General practice in an integrated NHS: reasons to be hopeful.

Moving from leadership of general practice to leadership involving all medical disciplines throughout the Coronavirus 2019 (COVID-19) pandemic provided a fascinating overview of the health and care landscape. There are many erroneous assumptions in secondary care about general practice, and vice versa, with professional tribalism a cause for concern. However, there are many examples of effective and straightforward integration, and the establishment of integrated care systems in England has provided a unique opportunity to address the commissioning challenges that had previously been barriers.

Micropatterning Decellularized ECM as a Bioactive Surface to Guide Cell Alignment, Proliferation, and Migration.

Bioactive surfaces and materials have displayed great potential in a variety of tissue engineering applications but often struggle to completely emulate complex bodily systems. The extracellular matrix (ECM) is a crucial, bioactive component in all tissues and has recently been identified as a potential solution to be utilized in combination with biomaterials. In tissue engineering, the ECM can be utilized in a variety of applications by employing the biochemical and biomechanical cues that are crucial to regenerative processes.

Pannexin 1 channels in renin-expressing cells influence renin secretion and blood pressure homeostasis.

Kidney function and blood pressure homeostasis are regulated by purinergic signaling mechanisms. These autocrine/paracrine signaling pathways are initiated by the release of cellular ATP, which influences kidney hemodynamics and steady-state renin secretion from juxtaglomerular cells. However, the mechanism responsible for ATP release that supports tonic inputs to juxtaglomerular cells and regulates renin secretion remains unclear.

A systematic review and meta-analysis of return to work after mild Traumatic brain injury.

Objective: To perform a systematic review and meta-analysis of return to work (RTW) times for adult patients with mild traumatic brain injury (mTBI).

Methods: Six databases and six trials registries were searched. Inclusion: studies reporting RTW, > 30 patients, adults, with mTBI.

Interaction Between Pannexin 1 and Caveolin-1 in Smooth Muscle Can Regulate Blood Pressure.

Objective- Sympathetic nerve innervation of vascular smooth muscle cells (VSMCs) is a major regulator of arteriolar vasoconstriction, vascular resistance, and blood pressure. Importantly, α-adrenergic receptor stimulation, which uniquely couples with Panx1 (pannexin 1) channel-mediated ATP release in resistance arteries, also requires localization to membrane caveolae. Here, we test whether localization of Panx1 to Cav1 (caveolin-1) promotes channel function (stimulus-dependent ATP release and adrenergic vasoconstriction) and is important for blood pressure homeostasis.

Bisphenol S modulates concentrations of bisphenol A and oestradiol in female and male mice.

Concern over endocrine-disrupting actions of bisphenol A (BPA) has prompted some manufacturers to remove it from consumer products. Among the chemical replacements in "BPA-free" products are other bisphenol analogues, such as bisphenol S (BPS). Given evidence that BPA and BPS possess similar oestrogenic activity, their capacity to interact and disrupt oestrogen homeostasis should be examined.

A mixture of five endocrine-disrupting chemicals modulates concentrations of bisphenol A and estradiol in mice.

Most people in developed countries are exposed to multiple endocrine-disrupting synthetic chemicals. We previously showed that a single dose of triclosan, tetrabromobisphenol A (TBBPA), butyl paraben, propyl paraben, or di(2-ethylhexyl) phthalate elevated concentrations of bisphenol A (BPA) in mice. Here we investigated whether concurrent exposure to lower doses of these five chemicals could modulate concentrations of bisphenol A (BPA) or the natural estrogen, 17β-estradiol (E2).

Butyl paraben and propyl paraben modulate bisphenol A and estradiol concentrations in female and male mice.

People are routinely exposed to the antimicrobial preservatives butyl paraben (BP) and propyl paraben (PP), as well as the monomer of polycarbonate plastics, bisphenol A (BPA). These chemicals are reliably detected in human urine and potentially interact. We investigated whether BP or PP exposure can modulate the concentrations of C-BPA and 17β-estradiol (E).

Microscopic change in macroscopically normal equine cartilage from osteoarthritic joints.

The objective of this study was to assess whether macroscopically normal articular cartilage taken from joints containing focal osteoarthritic lesions is histologically similar to articular cartilage taken from macroscopically normal joints. Metacarpophalangeal, proximal interphalangeal, and distal interphalangeal joints were obtained from 10 horses following euthanasia. Gross articular cartilage damage was scored and the cartilage assigned to one of two groups: (1) macroscopically normal cartilage from normal joints (control) and (2) macroscopically normal cartilage from diseased joints in which there were focal osteoarthritic lesions.
