BACKGROUND AND PURPOSE: Radiotherapy (RT) to the primary nasopharyngeal tumor is frequently offered to patients with metastatic nasopharyngeal carcinoma (mNPC). However, only limited data exist to support RT in this setting. We used the National Cancer Database (NCDB) to evaluate outcomes for mNPC patients receiving chemotherapy with and without local RT. METHODS: The NCDB was queried for patients with mNPC with synchronous metastatic disease at diagnosis who received chemotherapy...

BACKGROUND: Patients are at increased risk of disease recurrence after surgical treatment of Crohn's disease. Endoscopic detection of postoperative, ileo-colonic inflammation is well established, but the potential of pan-intestinal endoscopy is yet unknown. METHODS: This prospective multicenter pilot study assessed the value of pan-intestinal capsule endoscopy using a colon capsule endoscope for the detection of inflammatory recurrence of Crohn´s disease. Patients who had been operatively treated for Crohn´s disease were included...

Objective To examine associations of perceived stress with cognitive symptoms among adults with systemic lupus erythematosus (SLE). Methods Among 777 adult (≥18 years) SLE patients, the association of Perceived Stress Scale (PSS) scores with two self-reported cognitive symptoms was examined: forgetfulness (severe/moderate vs. mild/none; from the Systemic Lupus Activity Questionnaire) and difficulty concentrating (all/most vs. some/little/none of the time; from the Lupus Impact Tracker). The study used multivariable logistic regression to estimate the odds ratios (ORs) per minimal important difference (MID = 0...

BACKGROUND AND OBJECTIVES: Patients with CKD are asked to perform self-management tasks including dietary changes, adhering to medications, avoiding nephrotoxic drugs, and self-monitoring hypertension and diabetes. Given the effect of aging on functional capacity, self-management may be especially challenging for older patients. However, little is known about the specific challenges older adults face maintaining CKD self-management regimens. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS: We conducted an exploratory qualitative study designed to understand the relationship among factors facilitating or impeding CKD self-management in older adults...

Melanoma is the most aggressive and deadliest form of skin cancer. A detailed knowledge of the cellular, molecular and genetic events underlying melanoma progression is highly relevant to diagnosis, prognosis and risk stratification, and the development of new therapies. In the last decade, zebrafish have emerged as a valuable model system for the study of melanoma. Pathway conservation, coupled with the availability of robust genetic, transgenic and chemical tools, has made the zebrafish a powerful model for identifying novel disease genes, visualizing cancer initiation, interrogating tumor-microenvironment interactions and discovering new therapeutics that regulate melanocyte and melanoma development...

OBJECTIVE: Neurodegenerative diseases, such as dementia, have a profound impact on those with the conditions and their family carers. Consequently, the accurate measurement of family carers' quality of life (QOL) is important. Generic measures may miss key elements of the impact of these conditions, so using disease-specific instruments has been advocated. This systematic review aimed to identify and examine the psychometric properties of disease-specific outcome measures of QOL of family carers of people with neurodegenerative diseases (Alzheimer's disease and other dementias; Huntington's disease; Parkinson's disease; multiple sclerosis; and motor neuron disease)...

Despite the development of novel treatments in the past 15 years, many blood cancers still remain ultimately fatal and difficult to treat, particularly acute myeloid leukaemia (AML) and multiple myeloma (MM). While significant progress has been made characterising small-scale genetic mutations and larger-scale chromosomal translocations that contribute to the development of various blood cancers, less is understood about the complex microenvironment of the bone marrow (BM), which is known to be a key player in the pathogenesis of chronic lymphocytic leukaemia (CLL), AML and MM...

Acute Myeloid Leukaemia (AML) is a genetically, biologically and clinically heterogeneous set of diseases, which are characterised by an increased growth of abnormal myeloid progenitor cells within the bone marrow (BM). Ex-vivo AML exhibits a high level of spontaneous apoptosis. Furthermore, relapse for patients achieving remission occurs from minimal residual disease harboured within the BM microenvironment. Taken together, these observations illustrate the importance of the BM microenvironment in sustaining AML...

BACKGROUND: Adding induction chemotherapy to concurrent chemotherapy and radiotherapy (RT) has generally not improved the overall survival (OS) in randomized trials of patients with head and neck cancer. This failure may stem from inadequate power or inappropriate patient selection, prompting this National Cancer Data Base analysis. METHODS: 8031 patients with T4 or N2b to N3 disease undergoing RT and chemotherapy were divided into induction chemotherapy and concurrent chemotherapy cohorts...

Carbon nanomaterials have been used to treat neurodegenerative diseases and neural disorders due to their diverse molecular structures. Corannulene is a three-dimensional π-bowl carbon nanomaterial that is different from planar PAHs, fullerenes and carbon nanotubes, but little is known about its biological functions. Herein, corannulene was functionalized with mPEG-DESP to prepare PEGylation corannulene nanoparticles (PEGylation CoNps). The synthesized PEGylation CoNps shows enhanced solubility and reduced aggregation when compared corannulene...

REVIEW
Katsumi Iizuka
Many articles have discussed the relationship between fructose consumption and the incidence of obesity and related diseases. Fructose is absorbed in the intestine and metabolized in the liver to glucose, lactate, glycogen, and, to a lesser extent, lipids. Unabsorbed fructose causes bacterial fermentation, resulting in irritable bowl syndrome. Therefore, understanding the mechanisms underlying intestinal and hepatic fructose metabolism is important for the treatment of metabolic syndrome and fructose malabsorption...

BACKGROUND: Despite no demonstrated survival advantage for women at average risk of breast cancer, rates of contralateral prophylactic mastectomy (CPM) continue to increase. Research reveals women with higher socioeconomic status (SES) are more likely to select CPM. This study examines how indicators of SES, age, and disease severity affect CPM motivations. METHODS: Patients (N = 113) who underwent CPM at four Indiana University affiliated hospitals completed telephone interviews in 2013...

Musculoskeletal diseases have been associated with inflammatory cytokine action, particularly action by TNF-α and IL-1β. These inflammatory cytokines promote apoptosis and senescence of cells in diseased tissue and extracellular matrix breakdown. Stem cell-based therapies are being considered for the treatment of musculoskeletal diseases, but the presence of these inflammatory cytokines will have similar deleterious action on therapeutic cells delivered to these environments. Methods that prevent inflammatory-induced apoptosis and proinflammatory signaling, in cell and pathway-specific manners are needed...

Human infections with highly pathogenic avian influenza A (H5N1) virus are frequently fatal but the mechanisms of disease remain ill-defined. H5N1 infection is associated with intense production of proinflammatory cytokines, but whether this cytokine storm is the main cause of fatality or is a consequence of extensive virus replication that itself drives disease remains controversial. Conventional intratracheal inoculation of a liquid suspension of H5N1 influenza virus in nonhuman primates likely results in efficient clearance of virus within the upper respiratory tract and rarely produces severe disease...

Despite currently available therapies, most patients diagnosed with acute myeloid leukemia (AML) die of their disease. Tumor-host interactions are critical for the survival and proliferation of cancer cells; accordingly, we hypothesize that specific targeting of the tumor microenvironment may constitute an alternative or additional strategy to conventional tumor-directed chemotherapy. Because adipocytes have been shown to promote breast and prostate cancer proliferation, and because the bone marrow adipose tissue accounts for up to 70% of bone marrow volume in adult humans, we examined the adipocyte-leukemia cell interactions to determine if they are essential for the growth and survival of AML...
