BACKGROUND: In 2009, the Get With The Guidelines-Stroke (GWTG-Stroke) program offered additional recognition if hospitals performed well on certain stroke quality measures. We sought to determine whether quality of care for all hospitals participating in GWTG-Stroke improved with this expanded recognition program. METHODS AND RESULTS: We examined hospital-level performance on 6 quality of care (process) measures and 1 defect-free composite quality measure for stroke following expansion of the existing performance measure recognition program...

BACKGROUND: B-cells are essential in immunity against malaria, but which sub-sets of B-cells specifically recognize Plasmodium falciparum and when they appear is still largely unknown. RESULTS: Using the flow cytometry technique for detection of P. falciparum specific (Pf+) B-cells, this study for the first time measured the development of Pf+ B cell (CD19+) phenotypes in Ugandan babies from birth up to nine months, and in their mothers. The babies showed increases in Pf+ IgG memory B-cells (MBCs), atypical MBCs, and plasma cells/blasts over time, but the proportion of these cells were still lower than in the mothers who displayed stable levels (5, 18, and 3%, respectively)...

The contribution of somatic mutations to metastasis of colorectal cancers (CRC) is currently unknown. To find mutations involved in the CRC metastatic process, we performed deep mutational analysis of 676 genes in 107 stages II-IV primary CRC, of which half had metastasized. The mutation prevalence in the ephrin (Eph) family of tyrosine kinase receptors was ten-fold higher in primary tumors of metastatic CRC than in non-metastatic cases and preferentially occurred in stage III and IV tumours. Mutational analyses in situ confirmed expression of mutant Eph receptors...

Cryopreservation is the only existing method of storage of human adipose-derived stem cells (ASCs) for clinical use. However, cryopreservation has been shown to be detrimental to ASCs, particularly in term of cell viability. To restore the viability of cryopreserved ASCs, it is proposed to culture the cells in a hypoxic condition. To this end, we aim to investigate the effect of hypoxia on the cryopreserved human ASCs in terms of not only cell viability, but also their growth and stemness properties, which have not been explored yet...

OBJECTIVE: Despite the scientific evidence undoubtedly influencing current guidelines on the management of metastatic Breast cancer (mBC), marketing research data suggests this may not be reflected in EU prescribing behavior. Specifically we would like to understand the use of combination chemotherapy vs monotherapy in mBC patients. METHODOLOGY: This study is based on IMS Oncology Analyzer™, a web-based physician panel survey set-up by IMS Health, a global company which specializes in health care information including market research data...

OBJECTIVE: To determine drug resistance mutations and the HIV-1 subtypes among antiretroviral treatment naive HIV-1 patients in Peninsular Malaysia. METHODS: A total of 45 samples from four hospitals that provide HIV viral load services were subjected to the amplification of the protease and two third of reverse transcriptase regions of the pol gene by RT-PCR and Sanger sequencing. Drug resistance mutation (DRM) interpretation reports the presence of mutations related to protease inhibitors (PIs), Nucleoside reverse-transcriptase inhibitors (NRTI) and Non-nucleoside reverse-transcriptase inhibitors (NNRTI) based on analysis using Stanford HIV database program...

The histone chaperone HIRA is involved in depositing histone variant H3.3 into distinct genic regions, including promoters, enhancers, and gene bodies. However, how HIRA deposits H3.3 to these regions remains elusive. Through a short hairpin RNA (shRNA) screening, we identified single-stranded DNA binding protein replication protein A (RPA) as a regulator of the deposition of newly synthesized H3.3 into chromatin. We show that RPA physically interacts with HIRA to form RPA-HIRA-H3.3 complexes, and it co-localizes with HIRA and H3...

PURPOSE: To identify and evaluate possible causes of poor patient-reported visual function after cataract surgery. METHODS: We obtained retrospective data from the Swedish National Cataract Register on patient self-assessed visual function before and after cataract surgery based on the Catquest-9SF questionnaire. We identified patients who self-reported similar or more difficulties postoperatively than preoperatively, and looked at possible causative variables such as sex, age, preoperative and postoperative corrected distance visual acuity (CDVA) and refractive errors, and ocular comorbidity...

We describe the draft genome sequence of "Candidatus Methylomonas sp. LWB" isolated from Movile Cave microbial mat samples. The genome contains both the soluble and particular methane monooxygenase; however, one of the putative particulate methane monooxygenase gene clusters is ordered pmoABC rather than in the canonical gene arrangement of pmoCAB.

BACKGROUND: Incidence rates are fundamental to epidemiology, but their magnitude and interpretation depend on methodological choices. We aimed to examine the extent to which the definition of the study population affects cancer incidence rates. METHODS: All primary cancer diagnoses in Sweden between 1958 and 2010 were identified from the national Cancer Register. Age-standardized and age-specific incidence rates of 29 cancer subtypes between 2000 and 2010 were calculated using four definitions of the study population: persons resident in Sweden 1) based on general population statistics; 2) with no previous subtype-specific cancer diagnosis; 3) with no previous cancer diagnosis except non-melanoma skin cancer; and 4) with no previous cancer diagnosis of any type...

The Arctic icescape is rapidly transforming from a thicker multiyear ice cover to a thinner and largely seasonal first-year ice cover with significant consequences for Arctic primary production. One critical challenge is to understand how productivity will change within the next decades. Recent studies have reported extensive phytoplankton blooms beneath ponded sea ice during summer, indicating that satellite-based Arctic annual primary production estimates may be significantly underestimated. Here we present a unique time-series of a phytoplankton spring bloom observed beneath snow-covered Arctic pack ice...

The anaerobic, non-motile strain HMT was isolated from the naphthalene-degrading, sulfate-reducing enrichment culture N47. Since 20 years, strain HMT has been a stable member of culture N47 although it is neither able to degrade naphthalene nor to reduce sulfate in pure culture. The highest similarity of the 16S rRNA gene sequence of strain HMT (89%) is with a cultivated member of the family Spirochaetaceae, Treponema caldarium sp. strain H1T (DSM 7334T), an obligately anaerobic, thermophilic spirochete isolated from cyanobacterial mat samples collected at a freshwater hot spring in Oregon, USA...

BACKGROUND: Cervical range of motion (ROM) is commonly assessed in clinical practice and research. In a previous study we decomposed active cervical sagittal ROM into contributions from lower and upper levels of the cervical spine and found level- and direction-specific impairments in women with chronic non-specific neck pain. The present study aimed to validate these results and investigate if the specific impairments can be explained by the neutral posture (defining zero flexion/extension) or a movement strategy to avoid large gravitationally induced torques on the cervical spine...

PURPOSE: To assess the immunomodulatory and clinical effects of lenalidomide with standard treatment of gemcitabine in patients with advanced pancreatic cancer. PATIENTS AND METHODS: Patients with advanced pancreatic cancer were treated in first line with lenalidomide orally for 21 days of a 28 days cycle and the standard regimen for gemcitabine. In Part I, which we previously have reported, the dose of lenalidomide was defined (n = 12). In Part II, every other consecutive patient was treated with either lenalidomide (Group A, n = 11) or gemcitabine (Group B, n = 10) during cycle 1...

BACKGROUND: Gout is the most common inflammatory arthritic disease and is caused by crystal deposition secondary to persistent hyperuricemia. Etiological treatment with urate-lowering therapy (ULT) has been available since the 1950s but previous studies have demonstrated suboptimal degree of treatment. In recent years we have seen recommendations for ULT earlier in the course of the disease, but there are few contemporary reports reflecting the current situation. Therefore we set out to investigate proportion receiving and persisting with ULT after gout diagnosis and predictors thereof...

Semaphorin-7A is a glycosylphosphatidylinositol-anchored protein, initially characterized as an axon guidance protein. Semaphorin-7A also contributes to immune cell regulation and may be an essential pro-fibrotic factor when expressed by non-fibroblast cell types (exogenous). In mouse models, semaphorin-7A was shown to be important for TGF-ß1-induced pulmonary fibrosis characterized by myofibroblast accumulation and extracellular matrix deposition, but the cell-specific role of semaphorin-7A was not examined in fibroblasts...

The objective of this pilot study was to evaluate a 6-month exercise program completed by 10 older Caribbean Americans. Assessments were done at baseline, 3 and 6 months and included walks on an instrumented mat at preferred speed, and during street crossing simulations with regular (10s) and with reduced time (5s). There were no significant differences on preferred walking speed overtime. Differences between the street crossing conditions were found only at 6 months. Significant changes overtime among the assessments were found only during street crossing with reduced time...
