Determinants of Bluetooth-Enabled Self-Measured Blood Pressure Monitoring in Federally Qualified Health Centers.

Background: In 2021, the Health Resources and Services Administration (HRSA) launched the National Hypertension Control Initiative (HTN Initiative) with the goal to enhance HTN control through Bluetooth-enabled self-measured blood pressure (BT-SMBP) monitoring and use this data to inform clinical decisions in Federally Qualified Health Centers (FQHCs) with a large proportion of their population with uncontrolled blood pressure (BP). We sought to understand the experience of Michigan-based FQHCs in implementing the HTN initiative.

Methods: Staff from three Michigan-based FQHCs were invited to participate in semi-structured interviews from September to November 2022.

Reach Out Emergency Department: A Randomized Factorial Trial to Determine the Optimal Mobile Health Components to Reduce Blood Pressure.

Background: Mobile health (mHealth) strategies initiated in safety-net Emergency Departments may be one approach to address the US hypertension epidemic, but the optimal mHealth components or dose are unknown.

Methods: Reach Out is an mHealth, health theory-based, 2×2×2 factorial trial among hypertensive patients evaluated in a safety-net Emergency Department in Flint, Michigan. Reach Out consisted of 3 mHealth components, each with 2 doses: (1) healthy behavior text messaging (yes versus no), (2) prompted self-measured blood pressure (BP) monitoring and feedback (weekly versus daily), and (3) facilitated primary care provider appointment scheduling and transportation (yes versus no).

Short-term continuous intraparenchymal intracranial pressure monitoring in presumed idiopathic intracranial hypertension.

Background: The management of idiopathic intracranial hypertension (IIH) depends on a reliable assessment of intracranial pressure (ICP), particularly when visual function measures or ophthalmoscopic indicators are confusing and when invasive surgical procedures are being considered. Although ICP monitoring has been widely applied in many neurologic conditions as a more reliable measure of ongoing ICP than lumbar puncture (LP), it has not often been widely used in the management of IIH.

Methods: We searched the records of the University of Michigan between 2001 and 2008 for patients with IIH who had undergone LP and continuous ICP monitoring with an intraparenchymal Codman ICP Monitoring System and in whom at least 1 year of follow-up information was available.

Lessons learned from a woodstove changeout on the Nez Perce Reservation.

A woodstove changeout program was conducted within 16 homes on the Nez Perce Reservation in Idaho to evaluate the effectiveness of a woodstove changeout in improving indoor air quality. PM(2.5) samples were collected within the common area (rooms where the stoves were located) of the homes both before and after the installation of cleaner burning EPA-certified stoves.

Localized trabecular damage adjacent to interbody fusion devices.

Study Design: An in vitro cadaveric study of interbody fusion devices (IFDs) with differing interface geometries.

Objective: To quantify the trabecular damage and mechanical property degradation resulting from mechanical testing of bone-implant constructs and evaluate the dependence on the interface geometry.

Summary Of Background Data: The success of an orthopedic implant depends, in part, on the interaction between the implant and the bone at its interface.

Perineural spread of cancer along the three trigeminal divisions.

Perineural spread of head and neck cancers is a well-documented phenomenon, but the diagnosis is often delayed due to lack of familiarity with clinical manifestations, anatomy of the head and neck, and imaging signs. We present single cases of perineural spread along each of the 3 divisions of the trigeminal nerve in which the perineural spread was initially overlooked. Although perineural spread is often associated with a poor prognosis, earlier detection may improve outcome.

Comparisons of rates and forms of aggression among members of men's and women's collegiate recreational flag football teams.

The purpose of this study was to compare rates and forms of aggression among members of men's and women's recreational flag football teams during loosely supervised recreational periods on a college campus. We obtained data on forms of aggression using an event recording system. The data supported the hypothesis that overall rates of aggression were higher among male teams.

Perfusion-limited recovery of evoked potential function after spinal cord injury.

Study Design: The current study was designed to determine whether progressive spinal cord damage during residual compression is caused by low blood flow and ischemia.

Objectives: The purpose of this experiment was to determine the effects of sustained spinal cord compression on regional blood flow and evoked potential recovery after time-dependent decompression.

Summary Of Background Data: Spinal cord injury after trauma is commonly associated with residual cord compression.

Early time-dependent decompression for spinal cord injury: vascular mechanisms of recovery.

Although surgical decompression is often advocated for acute spinal cord injury, the timing and efficacy of early treatment have not been clinically proven. Our objectives were to determine the importance of early spinal cord decompression on recovery of evoked potential conduction under precision loading conditions and to determine if regional vascular mechanisms could be linked to electrophysiologic recovery. Twenty-one mature beagles were anesthetized and mechanically ventilated to maintain normal respiratory and acid-base balance.

Biomechanical evaluation of posterior cervical stabilization after a wide laminectomy.

Study Design: In vitro biomechanical investigation with nondestructive and destructive testing in a human cadaveric model simulating a wide postlaminectomy condition.

Objectives: To determine the relative stability conferred by a posterior cervical spinal rod system and posterior cervical plating.

Summary Of Background Data: Posterior cervical plate fixation has been shown to be biomechanically superior to wiring techniques, but lateral mass screws may injure neurovascular structures or facet joints if they are inserted improperly.

Viscoelastic relaxation and regional blood flow response to spinal cord compression and decompression.

Study Design: To better understand the relationships between primary mechanical factors of spinal cord trauma and secondary mechanisms of injury, this study evaluated regional blood flow and somatosensory evoked potential function in an in vivo canine model with controlled velocity spinal cord displacement and real-time piston-spinal cord interface pressure feedback.

Objectives: To determine the effect of regional spinal cord blood flow and viscoelastic cord relaxation on recovery of neural conduction, with and without spinal cord decompression.

Summary Of Background Data: The relative contribution of mechanical and vascular factors on spinal cord injury remains undefined.

Altered ovarian sterol carrier protein expression in the pregnant streptozotocin-treated diabetic rat.

Reproductive dysfunction in the diabetic female rat is associated with impaired folliculogenesis, reduced corpus luteum progesterone output, and spontaneous abortion. The underlying mechanism for reduced steroid production remains unresolved. In this study we examined whether or not diabetes alters levels of P450 side-chain cleavage enzyme (P450scc), 3 beta-hydroxysteroid dehydrogenase (3 beta-HSD), or the cholesterol transport proteins, steroidogenic acute regulatory (StAR) protein and sterol carrier protein-2 (SCP2), leading to lower progesterone levels and pregnancy loss.

Prostaglandin F2 alpha mediates ovarian sterol carrier protein-2 expression during luteolysis.

In the corpus luteum, prostaglandin F2 alpha (PGF2 alpha) appears to be a physiological agent with both antisteroidogenic and luteolytic actions. It is hypothesized that the antisteroidogenic action of PGF2 alpha acts through altered transport of cholesterol to the mitochondrial cytochrome P450 side-chain cleavage enzyme (P450scc). However, the effect of PGF2 alpha on the expression of the putative cholesterol transport protein, sterol carrier protein-2 (SCP2; 13.

Reduced hepatic sterol carrier protein-2 expression in the streptozotocin treated diabetic rat.

While a strong relationship between the hypercholesterolemia of diabetes and premature atherosclerosis is established, the etiology for the elevation in serum cholesterol in this disease is unknown. To determine whether diabetic hypercholesterolemia may be related to alterations in hepatic cholesterol transport capacity, sterol carrier protein-2 (SCP2) expression was examined in rats treated with streptozotocin (SZT). Furthermore, this study examined whether 17β-estradiol and insulin confer a protective effect on liver cholesterol homeostasis by maintaining hepatic SCP2 levels.

Differential expression of hepatic sterol carrier proteins in the streptozotocin-treated diabetic rat.

Sterol carrier protein-2 (SCP2) is a 13.2-kilodalton protein that has been implicated in intracellular cholesterol transport, whereas a related sterol carrier protein, sterol carrier protein-X (SCPx; 58 kilodaltons) has been suggested to function also in the beta-oxidation of fatty acids. Although diabetes-related hyperlipidemia and altered cholesterol metabolism have been extensively studied, the intracellular cholesterol transport capacity during hyperglycemic states has not been examined.

Compression strength of donor bone for posterior lumbar interbody fusion.

Forty-three blocks of allograft bone used clinically for posterior lumbar interbody fusion and twenty-three blocks of xenograft bone from goats and cows were tested in compression and compared with the clinical mechanical requirements of posterior lumbar interbody fusion. Variations in processing methods allowed evaluation of the effects of processing on mechanical strength. Fresh-frozen cancellous bone from Os Bone (Cleveland, OH) failed at an average load of 863 +/- 615 N.

Anterior spinal fixators. A biomechanical in vitro study.

In vitro calf spine testing was performed in flexion, rotation, and axial load, using a vertebral body corpectomy and anterior iliac crest bone grafting model. Anterior spinal fixation devices then were sequentially tested, and axial stiffness, torsional stiffness, and flexural strain determined. The constructs tested were the Contoured Anterior Spinal Plate (CASP), the Kaneda device, the Kostuik-Harrington device (KH), and the Texas Scottish Rite Hospital (TSRH) vertebral body screw construct.

Biomechanical study of sternal closure techniques.

Median sternotomy is the most commonly used incision in cardiothoracic surgery. Closure of this incision is usually performed with parasternal wires, but alternate techniques have been proposed to improve closure stability. This study compares biomechanical stability of standard wire (No.

A biomechanical analysis of solvent-dehydrated and freeze-dried human fascia lata allografts. A preliminary report.

Unlabelled: This study compares the basic mechanical properties of two groups of commercially available fascia lata allografts processed by different means (solvent-dehydrated and sterilized via gamma radiation, and freeze-dried without secondary sterilization). The results reveal significantly (P less than 0.05) higher stiffness, higher maximum load to failure, and higher maximum load per unit width of graft with the solvent-dried as opposed to the freeze-dried fascia lata.

Quantitative histologic study of the influence of anterior spinal instrumentation and biodegradable polymer on lumbar interbody fusion after corpectomy. A canine model.

Histomorphometric and microradiographic studies were performed to investigate whether there are different rates of bone remodeling based on the intrinsic stability with anterior spinal instrumentation and to evaluate if biodegradable polymer could be used clinically as the material of choice for anterior spinal instrumentation. Twenty-one coon hounds underwent anterior and posterior spinal destabilizing procedures to produce a reproducible amount of spinal instability: corpectomy of L5, discectomies and partial facetectomies of L4-5 and L5-6, resections of L5 lamina, spinous process, supra- and interspinous ligament, and ligamentum flavum. Group 1 (N = 7) underwent anterior autogenous ulna strut graft alone at L4-6; group 2 (N = 7) underwent anterior biodegradable polymer strut alone at the same level; group 3 (N = 7) underwent same bone graft as in group 1, augmented by anterior Kaneda device.

Influence of disc degeneration on mechanism of thoracolumbar burst fractures.

In order to clarify the pathomechanism of thoracolumbar burst fractures and to evaluate the influence of disc degeneration and bone mineral density, a biomechanical study was performed using cadaveric spines. Eleven motion segments of thoracolumbar spines from human cadavers were compressed vertically until a fracture occurred. In addition, bone mineral density and degree of disc degeneration were determined for each specimen.

Cervical stability after foraminotomy. A biomechanical in vitro analysis.

Laminectomy or facetectomy of the cervical spine, or both, may be needed for decompression of the spinal cord or of the nerve-roots. Acute stability of the cervical spine was tested after laminectomy and progressive staged foraminotomies in an in vitro model. Twelve cervical spines from human cadavera were used in the experiment.
