OBJECTIVE: Continuous EEG (cEEG) monitoring of critically ill patients has gained widespread use, but there is substantial reported variability in its use. We analyzed cEEG and antiseizure drug (ASD) usage at three high volume centers. METHODS: We utilized a multicenter cEEG database used daily as a clinical reporting tool in three tertiary care sites (Emory Hospital, Brigham and Women's Hospital and Yale - New Haven Hospital). We compared the cEEG usage patterns, seizure frequency, detection of rhythmic/periodic patterns (RPP), and ASD use between the sites...

Brandon J Klüg-Baerwald, R Mark Brigham
Hibernation is a period of water deficit for some small mammals, and humidity strongly influences hibernation patterns. Dry conditions reduce length of torpor bouts, stimulate arousals, and decrease overwinter survival. To mitigate these effects, many small mammals hibernate in near saturated (100% RH) conditions. However, big brown bats (Eptesicus fuscus) hibernate in a wider variety of conditions and tolerate lower humidity than most other bats. To assess arid tolerance in this species, we compared torpid metabolic rates (TMR) and rates of total evaporative water loss (TEWL) between two populations of E...

BACKGROUND: Osteoradionecrosis of the jaw (ORN) is an infrequent yet potentially devastating complication of radiation therapy to the head and neck region. Treatment options include antimicrobial therapy, local sequestrectomy, resection, and the use of hyperbaric oxygen (HBO). Published data on ORN are difficult to compare because of the lack of a universally accepted classification and staging system, and the literature on the use of HBO to either prevent or successfully manage ORN is controversial and inconclusive...

Polyhydroxyalkanoate (PHA) is a family of biodegradable polymers, and incorporation of different monomers can alter its physical properties. To produce the copolymer poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (P(3HB-co-3HV)) containing a high level of 3-hydroxyvalerate (3HV) by altering acetyl-CoA pool levels, we overexpressed an acetyl-CoA acetyltransferase (atoAD) in an engineered E. coli strain, YH090, carrying PHA synthetic genes bktB, phaB, and phaC. It was found that, with introduction of atoAD and with propionate as a co-substrate, 3HV fraction in PHA was increased up to 7...

BACKGROUND/PURPOSE: Previous cross sectional studies have shown that rheumatoid arthritis (RA) patients with fibromyalgia (FM) have higher disease activity, greater medical costs and worse quality of life compared to RA patients without FM. We determined the impact of FM on 2-year changes in functional status of RA patients in a prospective study. METHODS: Subjects included participants in the Brigham Rheumatoid Arthritis Sequential Study enrolled in a substudy of the effects of pain in RA...

The subtle energetic differences underpinning adjacent lanthanide discrimination are explored with diglycolamide ligands. Our approach converges liquid-liquid extraction experiments with solution-phase X-ray absorption spectroscopy (XAS) and density functional theory (DFT) simulations, spanning the lanthanide series. The homoleptic [(DGA)3Ln](3+) complex was confirmed in the organic extractive solution by XAS, and this was modeled using DFT. An interplay between steric strain and coordination energies apparently gives rise to a nonlinear trend in discriminatory lanthanide ion complexation across the series...

: 195 Background: Radiotherapy (RT) effectively palliates bone metastases, but relief may take weeks, frequently necessitating acute pain management (APM). NCCN Guidelines for Adult Cancer Pain (V2.2015) recommend initiation/titration of analgesics for patients with pain scale value (PSV) ≥ 4. We sought to evaluate how often symptomatic patients have analgesic regimens assessed and intervened upon at radiation oncology (RO) consult for bone metastases, and the impact of a dedicated palliative RO service on APM...

BACKGROUND: Intrauterine exposure to maternal smoking is linked to impaired executive function and behavioral problems in the offspring. Maternal smoking is associated with reduced fetal brain growth and smaller volume of cortical gray matter in childhood, indicating that prenatal exposure to tobacco may impact cortical development and manifest as behavioral problems. Cellular development is mediated by changes in epigenetic modifications such as DNA methylation, which can be affected by exposure to tobacco...

Despite advances in the medical and surgical management of cardiovascular disease, greater than 350,000 patients experience out-of-hospital cardiac arrest in the United States annually, with only a 12% neurologically favorable survival rate. Of these patients, 23% have an initial shockable rhythm of ventricular fibrillation/pulseless ventricular tachycardia (VF/VT), a marker of high probability of acute coronary ischemia (80%) as the precipitating factor. However, few patients (22%) will experience return of spontaneous circulation and sufficient hemodynamic stability to undergo cardiac catheterization and revascularization...

Importance: MicroRNAs (miRNAs) are promising multiple sclerosis (MS) biomarkers. Establishing the association between miRNAs and magnetic resonance imaging (MRI) measures of disease severity will help define their significance and potential impact. Objective: To correlate circulating miRNAs in the serum of patients with MS to brain and spinal MRI. Design, Setting, and Participants: A cross-sectional study comparing serum miRNA samples with MRI metrics was conducted at a tertiary MS referral center...

PROBLEM/CONDITION: Higher rates of death in nonmetropolitan areas (often referred to as rural areas) compared with metropolitan areas have been described but not systematically assessed. PERIOD COVERED: 1999-2014 DESCRIPTION OF SYSTEM: Mortality data for U.S. residents from the National Vital Statistics System were used to calculate age-adjusted death rates and potentially excess deaths for nonmetropolitan and metropolitan areas for the five leading causes of death...

BACKGROUND: The American Joint Committee on Cancer 7th edition (AJCC-7) and Brigham and Women's Hospital (BWH) staging criteria for cutaneous squamous cell carcinoma (cSCC) have not been validated in immunosuppressed patients. OBJECTIVE: To compare the AJCC-7 and BWH staging systems for cSCCs in immunosuppressed patients. METHODS AND MATERIALS: A single-institution retrospective cohort study of cSCCs in immunosuppressed patients. Risks of local recurrence (LR), nodal metastasis (NM), in-transit metastasis, and any poor outcome (PO) were compared among AJCC-7 and BWH tumor T stages...

BACKGROUND: Vitamin D has been linked to disease activity among patients with inflammatory bowel diseases (IBD). Prior investigation has also suggested that vitamin D levels may affect duration of therapy with anti-tumour necrosis factor-α (anti-TNF-α) medications among patients with IBD. AIM: To evaluate the relationship between vitamin D levels and odds of reaching remission while on an anti-TNF-α medication. METHODS: A total of 521 IBD patients enrolled in the Brigham and Women's IBD Centre database were eligible for inclusion...

BACKGROUND: Innovation has been a central focus of the Department of Surgery at the Brigham and Women's Hospital since its very inception. Here we review examples of innovations originating in this Department and analyze factors that have been critical to successful innovation. Finally, we discuss challenges to sustainability of innovation in this Department. METHODS: Narrative review of the literature, interviews, and personal observations. RESULTS: Examples of innovations reviewed here were each dependent on three critical elements: 1) multidisciplinary collaboration among surgical innovators and individuals outside of surgery who offered complementary skills and expertise, 2) a rich institutional environment that sustained a diverse complement of innovators working in close proximity, and 3) Department Chairmen who facilitated the work of innovators and promoted their contributions, rather than seeking personal prestige or financial gain...

BACKGROUND: The bacterium Staphylococcus aureus (SA) is known to induce allergic inflammatory responses, including through secreted staphylococcal enterotoxin (SE) superantigens. To quantify indoor environmental exposures to these potential allergens, which may be associated with worse asthma, we developed a method for the assessment of S. aureus and SE in home dust and applied it to a study of homes of inner-city adults with asthma. METHODS: We conducted laboratory experiments to optimize sample processing and real-time PCR methods for detection and quantification of SA (femB) and SEA-D, based on published primers...
