BACKGROUND: The fall peak in childhood asthma exacerbations is thought to be related to an increase in viral infections and allergen exposure when children return to school. Whether the seasonality of asthma attacks among children from different geographic regions follows similar trends is unclear. OBJECTIVE: To compare seasonal trends in asthma exacerbations among school-age children who lived in different geographic locations, with different climates, within the United States...

Radiological protection is a matter of concern for members of the public and thus national authorities are more likely to trust the quality of radioactivity data provided by accredited laboratories using common standards. Normative approach based on international standards aims to ensure the accuracy or validity of the test result through calibrations and measurements traceable to the International System of Units. This approach guarantees that radioactivity test results on the same types of samples are comparable over time and space as well as between different testing laboratories...

BACKGROUND: Folate binding protein(FBP) is an immunogenic protein over-expressed in endometrial(EC) and ovarian cancer(OC). We are conducting a phase I/IIa trial of E39 (GALE 301)+GM-CSF, an HLA-A2-restricted, FBP-derived peptide vaccine to prevent recurrences in disease-free EC and OC patients. This interim analysis summarizes toxicity, immunologic responses, and clinical outcomes to date. METHODS: HLA-A2+ patients were vaccinated(VG), and HLA-A2- or -A2+ patients were followed as controls(CG)...

The rough morphotypes of non-tuberculous mycobacteria have been associated with the most severe illnesses in humans. This idea is consistent with the fact that Mycobacterium tuberculosis presents a stable rough morphotype. Unlike smooth morphotypes, the bacilli of rough morphotypes grow close together, leaving no spaces among them and forming large aggregates (clumps). Currently, the initial interaction of macrophages with clumps remains unclear. Thus, we infected J774 macrophages with bacterial suspensions of rough morphotypes of M...

BACKGROUND: Galectin-3 (Gal3) plays diverse roles in cancer initiation, progression, and drug resistance depending on tumor type characteristics that are also associated with cancer stem cells (CSCs). Recurrence of breast carcinomas may be attributed to the presence of breast CSCs (BCSCs). BCSCs exist in mesenchymal-like or epithelial-like states and the transition between these states endows BCSCs with the capacity for tumor progression. The discovery of a feedback loop with galectins during epithelial-to-mesenchymal transition (EMT) prompted us to investigate its role in breast cancer stemness...

Peripheral T-cell lymphomas (PTCLs) represent a relatively uncommon heterogeneous group of non-Hodgkin's lymphomas (NHLs) with an aggressive clinical course and poor prognosis. Anthracycline-based multiagent chemotherapy with or without radiation therapy followed by first-line consolidation with high-dose therapy followed by autologous stem cell rescue (HDT/ASCR) is the standard approach to most of the patients with newly diagnosed PTCL. Relapsed or refractory disease is managed with second-line systemic therapy followed by HDT/ASCR or allogeneic stem cell transplant, based on the patient's eligibility for transplant...

Successful hip arthroscopy depends on proper patient selection and reasonable patient expectations. The purpose of this study is to report the results of hip arthroscopy in orthopaedic surgeons who represent the most informed cohort. This report is based on a retrospective review of prospectively collected data among 24 orthopaedic surgeons (1 bilateral). Follow-up averaged 48 months (range 12-120 months). They were all males with an average age of 45 years (range 30-64 years). All improved with an average of 18 points (preoperative 75; post-operative 93); although one underwent repeat arthroscopy and one was converted to total hip arthroplasty at 54 months...

Pain is highly prevalent among HIV-positive individuals, with women representing a large subset of those with pain. However, little is known about the relationship between pain and retention in HIV medical care. Among a cohort of HIV-positive women of color, we evaluated the association between pain and retention in care, as measured by missed clinic visits. The Health Resources and Services Administration's Women of Color Initiative was a multi-site observational cohort study evaluating demonstration projects to engage HIV-positive women in medical care...

J W Thomas Byrd
Iatrogenic instability of the hip is likely a perfect storm with enough factors coming together just wrong to create the problem. Capsular neglect is but one potential component. Instability is also just one of a myriad of problems that can be encountered following hip arthroscopy that ranges on a spectrum from too loose to too stiff with numerous reasons in between for incomplete pain relief and residual dysfunction. Proper capsular management does not always mean capsular repair.

Hip disorders are increasingly recognized among athletic populations. The rigors of military service expose individuals to the same risks as those participating in competitive sports, compounded by potential exposure to violent macrotrauma. This is a retrospective review of prospectively collected data among 62 active duty military personnel (64 hips) with 2-10-year follow-up. Follow-up averaged 47 months (range 24-120 months). The average age was 30 years (range 17-53 years) with 45 males and 17 females; 37 right and 27 left hips...

Myeloid-derived suppressor cells (MDSC) are a heterogeneous group of immature myeloid cells that expand in tumor-bearing hosts in response to soluble factors produced by tumor and stromal cells. MDSC expansion has been linked to loss of immune effector cell function and reduced efficacy of immune-based cancer therapies, highlighting the MDSC population as an attractive therapeutic target. Ibrutinib, an irreversible inhibitor of Bruton's tyrosine kinase (BTK) and IL2-inducible T-cell kinase (ITK), is in clinical use for the treatment of B-cell malignancies...

Diffuse large B-cell lymphomas (DLBCL) are now considered a heterogeneous group of distinct molecular subtypes (germinal center B-cell DLBCL, activated B-cell DLBCL, and primary mediastinal large B-cell lymphoma (PMBL) with varied natural history and response to therapy. In addition, a subset of patients with DLBCL have concurrent MYC and/or BCL2 gene rearrangements (double-hit lymphomas; DHL) and others have a dual expression of both MYC and BCL2 proteins (double-expressing DLBCL; DEL). The standard of care for the treatment of patients with PMBL, DHL, or DEL has not been established...

Approximately 20% of rural Alaskan homes lack in-home piped water; residents haul water to their homes. The limited quantity of water impacts the ability to meet basic hygiene needs. We assessed rates of infections impacted by water quality (waterborne, e.g. gastrointestinal infections) and quantity (water-washed, e.g. skin and respiratory infections) in communities transitioning to in-home piped water. Residents of four communities consented to a review of medical records 3 years before and after their community received piped water...

Charting differences between tumors and normal tissue is a mainstay of cancer research. However, clonal tumor expansion from complex normal tissue architectures potentially obscures cancer-specific events, including divergent epigenetic patterns. Using whole-genome bisulfite sequencing of normal B cell subsets, we observed broad epigenetic programming of selective transcription factor binding sites coincident with the degree of B cell maturation. By comparing normal B cells to malignant B cells from 268 patients with chronic lymphocytic leukemia (CLL), we showed that tumors derive largely from a continuum of maturation states reflected in normal developmental stages...

BACKGROUND: Irreversible inhibition of Bruton's tyrosine kinase (BTK) by ibrutinib represents an important therapeutic advance for the treatment of chronic lymphocytic leukemia (CLL). However, ibrutinib also irreversibly inhibits alternative kinase targets, which potentially compromises its therapeutic index. Acalabrutinib (ACP-196) is a more selective, irreversible BTK inhibitor that is specifically designed to improve on the safety and efficacy of first-generation BTK inhibitors. METHODS: In this uncontrolled, phase 1-2, multicenter study, we administered oral acalabrutinib to 61 patients who had relapsed CLL to assess the safety, efficacy, pharmacokinetics, and pharmacodynamics of acalabrutinib...

REVIEW
John W Thomas Byrd
Arthroscopic techniques for the hip joint have evolved into endoscopic methods for extra-articular disorders. These endoscopic strategies provide a less invasive alternative to open procedures for traditionally recognized forms of pathology. Endoscopy has defined new disorders amenable to surgical correction and has redefined some of these existing disorders. The peritrochanteric and deep gluteal regions represent 2 of the most currently active areas of exploration. Peritrochanteric problems include trochanteric bursitis, full-thickness and partial-thickness tears of the abductors including the gluteus medius and minimus, and external coxa saltans (snapping iliotibial band)...
