Purpose: Therapeutic regimens for adult T-cell leukemia/lymphoma (ATL) are limited with unsatisfactory results, thereby warranting development of novel therapies. This study investigated antitumor activity and toxicity of alemtuzumab with regard to response, duration of response, progression-free survival, and overall survival in patients with human T-cell lymphotropic virus-1 (HTLV-1)-associated ATL.

Experimental Design: Twenty-nine patients with chronic, acute, and lymphomatous types of ATL were enrolled in a single-institution, nonrandomized, open-label phase II trial wherein patients received intravenous alemtuzumab 30 mg three times weekly for a maximum of 12 weeks.

Background: The Work Disability Functional Assessment Battery (WD-FAB), developed for potential use by the US Social Security Administration to assess work-related function, currently consists of five multi-item scales assessing physical function and four multi-item scales assessing behavioral health function; the WD-FAB scales are administered as Computerized Adaptive Tests (CATs).

Objective: The goal of this study was to evaluate the test-retest reliability of the WD-FAB Physical Function and Behavioral Health CATs.

Methods: We administered the WD-FAB scales twice, 7-10 days apart, to a sample of 376 working age adults and 316 adults with work-disability.

Association of early imaging for back pain with clinical outcomes in older adults.

JAMA

March 2015

Department of Family Medicine, Internal Medicine, and Public Health and Preventive Medicine, and the Oregon Institute for Occupational Health Sciences, Oregon Health and Science University, Portland.

Importance: In contrast to the recommendations for younger adults, many guidelines allow for older adults with back pain to undergo imaging without waiting 4 to 6 weeks. However, early imaging may precipitate interventions that do not improve outcomes.

Objective: To compare function and pain at the 12-month follow-up visit among older adults who received early imaging with those who did not receive early imaging after a new primary care visit for back pain without radiculopathy.

Background: Chemotherapy-induced peripheral neuropathy (CIPN) is a complication commonly involving extremities characterized by dysthesias. Given the predilection towards diminished proprioceptive feedback, balance and gait deficits often result, leading to an increase in falls risk. To date there is no published evidence to support the use of orthotics in the treatment of balance dysfunction secondary to CIPN.

First in line: prioritizing receipt of Social Security disability benefits based on likelihood of death during adjudication.

Med Care

November 2014

*Epidemiology and Biostatistics Section, Rehabilitation Medicine Department, National Institutes of Health, Mark O. Hatfield Clinical Research Center, Bethesda, MD †Institute on Disability, University of New Hampshire, Durham, NH.

Background: Given the complexity of the adjudication process and volume of applications to Social Security Administration's (SSA) disability programs, many individuals with serious medical conditions die while awaiting an application decision. Limitations of traditional survival methods called for a new empirical approach to identify conditions resulting in rapid mortality.

Objective: To identify health conditions associated with significantly higher mortality than a key reference group among applicants for SSA disability programs.

Potential therapies are currently under development for two congenital muscular dystrophy (CMD) subtypes: collagen VI-related muscular dystrophy (COL6-RD) and laminin alpha 2-related dystrophy (LAMA2-RD). However, appropriate clinical outcome measures to be used in clinical trials have not been validated in CMDs. We conducted a two-year pilot study to evaluate feasibility, reliability, and validity of various outcome measures, particularly the Motor Function Measure 32, in 33 subjects with COL6-RD and LAMA2-RD.

Bisphosphonate treatment for children with disabling conditions.

PM R

May 2014

Rehabilitation Medicine Department, Mark O. Hatfield Clinical Research Center, National Institutes of Health, Bethesda, MD(‡).

Fractures are a frequent source of morbidity in children with disabling conditions. The assessment of bone density in this population is challenging, because densitometry is influenced by dynamic forces affecting the growing skeleton and may be further confounded by positioning difficulties and surgical hardware. First-line treatment for pediatric osteoporosis involves conservative measures, including optimizing the management of underlying conditions, maintaining appropriate calcium and vitamin D intake, encouraging weight-bearing physical activity, and monitoring measurements of bone mineral density.

Background: Pulmonary arterial hypertension is a rare disorder associated with poor survival. Endothelial dysfunction plays a central role in the pathogenesis and progression of pulmonary arterial hypertension. Inflammation appears to drive this dysfunctional endothelial phenotype, propagating cycles of injury and repair in genetically susceptible patients with idiopathic and disease-associated pulmonary arterial hypertension.

NEURO-ONCOLOGIC PHYSICAL THERAPY FOR THE OLDER PERSON.

Top Geriatr Rehabil

July 2011

Staff Physical Therapist, Department of Health and Human Services, National Institutes of Health, Mark O. Hatfield Clinical Research Center, Rehabilitation Medicine Department, Physical Therapy Section, Bethesda, Maryland.

Due to the uncertainty of the course of diagnoses, patients with neuro-oncological malignancies present challenges to the physical therapist. At times, the presentation of impairments and disabilities of these patients with neuro-oncological diagnoses do not necessarily coincide with the involved area of the brain or spinal cord. It is our intention to provide guidance to the physical therapist who will be working with these patients with neuro-oncological diagnoses, in hopes that their encounters will be more productive and meaningful.

Metabolism Branch, Center for Cancer Research, National Cancer Institute, Mark O. Hatfield Clinical Research Center, Bethesda, Maryland 20892-1457, USA.

T-Cell leukemias and lymphomas represent a less common and heterogeneous group of lymphoid neoplasms. Overall, they respond less well to chemotherapy and have a poorer prognosis than their B-cell counterparts. T-Cell tumors express a number of potential targets for receptor-directed antibody therapy; however, there is no available therapeutic monoclonal antibody for these diseases with comparable activity to that of rituximab in B-cell disorders.
