OBJECTIVE: To examine the psychosocial outcomes and impact of attention problems in survivors of pediatric brain tumor. STUDY DESIGN: The survivors' cognitive functioning was measured using the Wechsler Intelligence Scale for Children. The Child Behavior Checklist-Attention Problems scale was used to screen for attention problems, and participants were classified as having attention problems (n=15) or normal attention (n=36). Psychosocial functioning was examined with the Korean Personality Rating scale for Children (K-PRC) at precraniospinal radiation and at 2-year follow-up...

BACKGROUND: Recent studies have demonstrated diminished cognitive function, worse quality of life, and no overall survival benefit from the addition of adjuvant whole brain radiation therapy (WBRT) to stereotactic radiosurgery (SRS) in the management of brain metastases. This study analyzes the treatment outcome of SRS, specifically CyberKnife Radiosurgery, based on the total tumor volume compared to the absolute number of lesions. METHODS: A retrospective analysis of hospital records at Virginia Hospital Center for patients with brain metastases who underwent CyberKnife Radiosurgery between June 2008 and June 2014 was performed...

REVIEW
Feng Ru Tang, Weng Keong Loke, Boo Cheong Khoo
Animal experimental studies indicate that acute or chronic low-dose ionizing radiation (LDIR) (≤100 mSv) or low-dose-rate ionizing radiation (LDRIR) (<6 mSv/h) exposures may be harmful. It induces genetic and epigenetic changes and is associated with a range of physiological disturbances that includes altered immune system, abnormal brain development with resultant cognitive impairment, cataractogenesis, abnormal embryonic development, circulatory diseases, weight gain, premature menopause in female animals, tumorigenesis and shortened lifespan...

PURPOSE: After radiation therapy (RT) to the brain, patients often experience memory impairment, which may be partially mediated by damage to the hippocampus. Hippocampal sparing in RT planning is the subject of recent and ongoing clinical trials. Calculating appropriate hippocampal dose constraints would be improved by efficient in vivo measurements of hippocampal damage. In this study we sought to determine whether brain RT was associated with dose-dependent hippocampal atrophy. METHODS AND MATERIALS: Hippocampal volume was measured with magnetic resonance imaging (MRI) in 52 patients who underwent fractionated, partial brain RT for primary brain tumors...

BACKGROUND: There is significant need for quality follow-up care to optimize long-term outcomes for the growing population of lower gastrointestinal (GI) cancer survivors. Patient-reported outcomes (PROs) provide valuable information regarding late and long-term effects (LLTEs). METHODS: A convenience sample from 1129 colon, rectal, and anal cancer survivors (n = 792; 218, and 119, respectively) who participated in an Internet-based survivorship care plan (SCP) tool between May 2010 and October 2014 was used to examine patient-reported demographics, treatment, and toxicity data...

: There has been increasing use of CT scans globally. This increased use is not in itself of concern, and largely reflects the remarkable clinical benefits of CT. Inappropriate use of CT is, however, of concern, particularly as the potential for carcinogenic effects is yet to be fully understood. The first major media attention to cancer risk from CT scan arose from a series of papers and an Editorial published in AJR in 2001. This was followed by another series of papers in 2007 and associated media attention to the estimation of the number of cancer deaths that may occur in US as a result of radiation exposure from CT...

PURPOSE: Thinning of the cerebral cortex has been observed in patients treated with fractionated partial brain radiation therapy and may contribute to cognitive decline following treatment. The extent of this thinning is dose-dependent, and was shown comparable to that of neurodegenerative diseases such as Alzheimer's disease at one year post-therapy. This study investigates whether 4π radiotherapy can enable better sparing of the cortex and other critical structures when compared to conventional clinical IMRT plans...

PURPOSE: Cognitive impairment from radiation therapy to the brain may be linked to the loss of total blood volume in the brain. To account for brain injury, it is crucial to develop an understanding of blood volume loss as a result of radiation therapy. This study investigates µCT based quantification of mouse brain vasculature, focusing on the effect of acquisition technique and contrast material. METHODS: Four mice were scanned on a µCT scanner (Siemens Inveon)...

Objective This update of the 2008 American Academy of Otolaryngology-Head and Neck Surgery Foundation cerumen impaction clinical practice guideline provides evidence-based recommendations on managing cerumen impaction. Cerumen impaction is defined as an accumulation of cerumen that causes symptoms, prevents assessment of the ear, or both. Changes from the prior guideline include a consumer added to the development group; new evidence (3 guidelines, 5 systematic reviews, and 6 randomized controlled trials); enhanced information on patient education and counseling; a new algorithm to clarify action statement relationships; expanded action statement profiles to explicitly state quality improvement opportunities, confidence in the evidence, intentional vagueness, and differences of opinion; an enhanced external review process to include public comment and journal peer review; and 3 new key action statements on managing cerumen impaction that focus on primary prevention, contraindicated intervention, and referral and coordination of care...

Patients with multiple sclerosis (MS) commonly exhibit cognitive impairments (CI). However, the neural mechanisms underlying CI remain unclear. The current study applied diffusion tensor imaging (DTI) and voxel-based morphometric (VBM) magnetic resonance imaging (MRI) techniques to evaluate differences in white matter (WM) integrity and gray matter (GM) volume between MS patients with CI and MS patients with cognitive preservation (CP). Neuropsychological assessment and MRI were obtained from 39 relapsing-remitting MS (RRMS) patients and 29 healthy controls (HCs)...

INTRODUCTION: The characteristics of dementia with Lewy bodies (DLB), Alzheimer's disease (AD) and amnestic mild cognitive impairment (a-MCI) overlap but require different treatments; therefore, it is important to differentiate these pathologies. Assessment of dopamine uptake in the striatum using dopamine transporter (DaT) single-photon emission computed tomography (SPECT) is the gold standard for diagnosing DLB; however, this modality is expensive, time consuming and involves radiation exposure...

OBJECTIVE: Despite the efficacy of clinical treatments (e.g., adjuvant hormonal therapy) for breast cancer survivors (BCS), nonadherence rates remains high, increasing the risk of recurrence and mortality. The current study tested a theoretical model of medical nonadherence that proposes depression to be the most proximal predictor of medical nonadherence among BCS. METHODS: BCS were recruited from radiation clinics in Missouri. Survey data were collected 12 months after the end of primary treatment...

Purpose Cancer-related cognitive impairment is an important problem for patients with breast cancer, yet its trajectory is not fully understood. Some previous cancer-related cognitive impairment research is limited by heterogeneous populations, small samples, lack of prechemotherapy and longitudinal assessments, use of normative data, and lack of generalizability. We addressed these limitations in a large prospective, longitudinal, nationwide study. Patients and Methods Patients with breast cancer from community oncology clinics and age-matched noncancer controls completed the Functional Assessment of Cancer Therapy-Cognitive Function (FACT-Cog) at prechemotherapy and postchemotherapy and at a 6-month follow-up as an a priori exploratory aim...
