American College of Surgeons verified trauma centers and a third party payer within the state of Michigan built a regional collaborative quality initiative (CQI). The Michigan Trauma Quality Improvement Program began as a pilot in 2008 and expanded to a formal program in 2011. Here, we examine the performance of the collaborative over time with regard to patient outcomes, resource utilization, and process measures.
This paper presents a wireless system to send biosignals outside a hyperbaric chamber avoiding wires going through the chamber walls. Hyperbaric chambers are becoming more and more common due to new indications of hyperbaric oxygen treatments. Metallic walls physically isolate patients inside the chamber, where getting a patient's vital signs turns into a painstaking task. The paper proposes using a ZigBee-based network to wirelessly transmit the patient's biosignals to the outside of the chamber. In partic...
The Michigan Hand Outcomes Questionnaire has been widely used for nearly 20 years to assess patients with a variety of hand and upper extremity conditions. However, normative data have not previously been collected, limiting interpretation.
To compare endothelial cell (EC) variation after anterior chamber phakic intraocular lens (AC-pIOL) implantation in highly myopic patients with a preoperative anterior chamber depth (ACD) between 2.8 and 3.0 versus ≥3.0 mm.
In 1973-1974, Michigan residents were exposed to polybrominated biphenyls (PBBs) through an accidental contamination of the food supply. Residents were enrolled in a registry assembled after the incident, and they and their children participated in follow-up studies to assess subsequent health outcomes.
High frequencies of antimicrobial drug resistance were observed in O157 and non-O157 Shiga toxin-producing E. coli strains recovered from patients in Michigan during 2010-2014. Resistance was more common in non-O157 strains and independently associated with hospitalization, indicating that resistance could contribute to more severe disease outcomes.
We examined the effectiveness and adverse events of using balanced salt solution (BSS) PLUS containing 0.025% povidone-iodine, a non-oculotoxic concentration, for capsular bag irrigation in a case of endophthalmitis mainly involving the anterior chamber. A 57-year-old female underwent cataract surgery and developed hypopyon on day 3 after surgery, with mainly anterior chamber inflammation. The capsular bag was irrigated with BSS PLUS containing 0.025% povidone-iodine. Gram-negative rods were detected from t...
In this paper, we propose the use of a pixelated transmission chamber, placed between the patient and the imaging detector, to measure the scatter component of a radiation beam impinging on said imaging detector. Using Monte Carlo simulation, a three-parameter model for the propagation of the scatter component in the transmitted beam is first developed. The use of the transmission chamber to determine the model parameters is then modeled, again using Monte Carlo simulation, and the feasibility of this appro...
The article presents the advantages of the radon chamber with volume of 17 m3, that belongs to Silesian Centre for Environmental Radioactivity and its applicability for calibration of equipment designed to measure the radon concentration and its short-lived decay products. The chamber can be operated under controlled conditions in the range from -20 to 60°C and relative humidity from 20 to 90%. There is also discussed the influence of aerosol concentration and their size distribution on the calibration res...
The aim of this study was to examine the effect of sub-millimeter air gaps that may exist between an ionization chamber and solid phantoms when measurements are performed in a magnetic field.
To improve survival of patients resuscitated from out of hospital cardiac arrest (OCHA), data is needed to assess and improve inpatient post-resuscitation care. Our objective was to apply probabilistic linkage methodology to link EMS and inpatient databases and evaluate whether it may be used to describe post-arrest care in Michigan.
Tracking sewage wastewater in a large lake is difficult. Concentrations of pharmaceuticals that can be used as indicator compounds are quickly diluted and not easy to measure. In this study, we examined the potential of using medically-derived iodine-131 ((131)I, t½ = 8.02 d) as a tracer for Milwaukee sewage effluent in Lake Michigan. (131)I activities in sewage effluent from two Milwaukee wastewater treatment plants (WWTPs) were measured in conjunction with (131)I activities in water, sediment and biot...
Previous studies have examined the impact of Clinical and Translational Science Awards programs on other outcomes, but not on grant seeking. The authors examined the effects on grant seeking of the Michigan Institute for Clinical & Health Research (MICHR), a Clinical and Translational Science Awards institute at the University of Michigan.
Increased resource utilization and overall morbidity are associated with general versus regional anesthesia for carotid endarterectomy in data collected by the Michigan Surgical Quality Collaborative.
Advocates for performing carotid endarterectomy (CEA) under regional anesthesia (RA) cite reduction in hemodynamic instability and the ability for neurologic monitoring, but many still prefer general anesthesia (GA) as benefits of RA have not been clearly demonstrated, reliable RA may not be available in all centers, and a certain amount of movement by the patient during the procedure may not be uniformly tolerated. We evaluated the association of anesthesia type and perioperative morbidity and mortality as...
To validate the effects of the new plateau hyperbaric chamber on alleviating high altitude hypoxia on Mount Kun Lun.
Conditions in which exhaled and dermally-emitted bioeffluents could be sampled separately or together (whole-body emission) were created. Five lightly-dressed males exhaled the air through a mask to another, identical chamber or without a mask to the chamber in which they were sitting; the outdoor air supply rate was the same in both chambers. The carbon dioxide concentration in the chamber with exhaled air was 2,000 ppm. Chamber temperatures were 23°C or 28°C and ozone was present or absent in the supply...
Nursing home bed-hold policies provide continuity of care for Medicaid beneficiaries by paying nursing homes to reserve beds so residents can return to their facility of occupancy following an acute hospitalization. In 2001, Michigan implemented bed-hold policies in nursing homes. We investigated the impact of these policies on mortality and hospitalizations using 1999-2004 quarterly data from nursing homes in Michigan and nursing homes in 11 states that did not implement such policies. Synthetic Control ha...
Contaminated sediment can release hydrophobic organic contaminants (HOCs) and thereby act as a secondary source of primarily legacy hazardous substances to the water column. There is therefore a need for assessments of the release of HOCs from contaminated sediment for prioritization of management actions. In situ assessment of HOC sediment-to-water flux is currently done with (closed) benthic flux chambers, which have a sampling time exceeding one month. During this time, the water inside the chamber is de...
Geographic clustering of bystander CPR is associated with demographic and socioeconomic features of the community where out-of-hospital cardiac arrest (OHCA) occurred, though this association remains largely untested in rural areas. With a significant rural component and relative racial homogeneity, Kent County, Michigan provides a unique setting to externally validate or identify new community features associated with bystander CPR. Using a large, countywide dataset, we tested for geographic clustering of ...
The aim of this study was to investigate changes in the anterior segment of the eye after cycloplegia. A biometer combined with swept-source optical coherence tomography (SSOCT) was used for measurements. Patients with strabismus or amblyopia who underwent cycloplegia were included. The axial length, central corneal thickness, anterior chamber depth, and lens thickness were measured with the biometer-SSOCT system before and after cycloplegia. Altogether, 10 eyes of 10 patients (mean age 7.20 ± 3.08 years, ...
Our purpose was to describe the clinical course, and individualized management approaches, of patients with migration of a dexamethasone implant into the anterior chamber.
To provide results of water calorimetry and ion chamber measurements in high-energy electron beams carried out at the National Research Council Canada (NRC). There are three main aspects to this work: 1) investigation of the behavior of ionization chambers in electron beams of different energies with focus on long-term stability, 2) water calorimetry measurements to determine absorbed dose to water in high-energy beams for direct calibration of ion chambers, and 3) using measurements of chamber response rel...
Here, we describe the development of the MosqTent, an innovative double-chamber mosquito trap in which a human being attracts mosquitoes while is protected from being bitten within the inner chamber of the trap, while mosquitoes are lured to enter an outer chamber where they are trapped. The MosqTent previously collected an average of 3,000 anophelines/man-hour compared to 240 anophelines/man-hour for the human landing catch (HLC), thereby providing high numbers of human host-seeking mosquitoes while protec...
This study aimed to describe the commissioning of small field size radiosurgery cones in a 6-MV flattening filter free (FFF) beam and report our measured values. Four radiosurgery cones of diameters 5, 10, 12.5, and 15 mm supplied by Elekta Medical were commissioned in a 6-MV FFF beam from an Elekta Versa linear accelerator. The extraction of a reference signal for measuring small fields in scanning mode is challenging. A transmission chamber was attached to the lower part of the collimators and used for ...
