Exosomes are emerging mediators of intercellular communication; whether the release of exosomes has an effect on the exosome donor cells in addition to the recipient cells has not been investigated to any extent. Here, we examine different exosomal miRNA expression profiles in primary mouse colon tumour, liver metastasis of colon cancer and naive colon tissues. In more advanced disease, higher levels of tumour suppressor miRNAs are encapsulated in the exosomes. miR-193a interacts with major vault protein (MVP)...

BACKGROUND: Per WHO, 2000 classification, pancreatic mucinous cystic neoplasms (MCN) are defined by presence of ovarian stroma, and are primarily located in the pancreatic body/tail of females. The incidence of MCN and associated malignancy in males, since, standardization of MCN diagnostic-criteria is unknown. METHODS: MCN resections from 2000 to 2014 at eight institutions of the Central-Pancreas-Consortium were included, and divided into early (2000-2007) and late (2008-2014) time-periods...

PURPOSE OF REVIEW: Hypertension and hyperlipidemia represent two major risk factors for atherosclerotic cardiovascular disease. Mobile health or mHealth is defined as the use of mobile phone and wireless technologies to support the achievement of health objectives. Management of hypertension, and to some extent hyperlipidemia, has often employed mHealth interventions given lower cost and greater patient engagement compared to traditional methods. These interventions include the use of text messaging, wireless devices, and mobile phone applications...

An important consideration for the successful use of fresh osteochondral allografts for the patellofemoral joint is selection of appropriately sized donor allografts. This is particularly challenging for matching grafts to the patella because of the substantial variability in articular contour that exists. At present, selection of donor patellae is based only on the width of the proximal tibia, with no established means of quantifying basic patellar size, facet configuration, or articular contour. We hypothesized that using a combination of standard radiographic measurements to generate an accurate profile of the recipients native patella would result in a more accurate donor graft...

Neurovascular coupling (NVC) describes the link between an increase in task related neural activity and increased cerebral blood flow denoted "functional hyperemia". We previously showed induced cerebral blood flow oscillations suppressed functional hyperemia; conversely functional hyperemia also suppressed cerebral blood flow oscillations. We used lower body negative pressure (OLBNP) oscillations to force oscillations in middle cerebral artery cerebral blood flow velocity (CBFv). Here, we used N-Back testing, an intellectual memory challenge as a neural activation task, to test the hypothesis that OLBNP-induced oscillatory cerebral blood flow (OCBF) can reduce functional hyperemia and NVC produced by a working memory task, and can interfere with working memory...

Childhood-onset craniopharyngiomas are rare embryonic tumours of low-grade histological malignancy. Novel insights into the molecular pathogenesis of human adamantinomatous craniopharyngioma have started to unveil the possibility of testing novel treatments targeting pathogenic pathways. Hypothalamic involvement and/or treatment-related lesions result in impaired physical and social functionality and in severe neuroendocrine sequelae. Quality of survival in patients with craniopharyngioma with hypothalamic involvement is impaired by severe obesity, physical fatigue and non-optimal psychosocial development...

BACKGROUND: Diabetes kills more than 4.9 million adults per year. It becomes rapidly increasing, non-communicable disease-a major threat to global public health particularly in Sub-Saharan Africa. Though previous studies among diabetic patients were focused in health institution, limited knowledge, attitude and practice were seen. There is no study conducted about diabetes related to knowledge, attitudes, practice and associated factors in the community level. OBJECTIVE OF THE STUDY: The study assessed knowledge, attitude, practices, and its associated factors towards diabetes mellitus among non diabetic community members of Bale Zone, Ethiopia...

REVIEW
Anwar T Merchant, Salim S Virani
PURPOSE OF REVIEW: Periodontal disease is correlated with cardiovascular disease (CVD) in observational studies, but a causal connection has not been established. The empirical evidence linking periodontal disease and CVD consists of a large body of observational and mechanistic studies, but a limited number of clinical trials evaluating the effects of periodontal treatment on surrogate CVD endpoints. RECENT FINDINGS: No randomized controlled trial has been conducted to evaluate the effect of periodontal treatment on CVD risk...

OBJECTIVES: Fatty liver disease (FLD) is frequently observed in HIV-infected patients. Obesity and type 2 diabetes mellitus (T2DM) are strongly associated with FLD. Because genetic variants within the fat mass and obesity-associated (FTO) gene have been associated with both pathologies, our aim was to evaluate the association of single nucleotide polymorphisms (SNPs) within the FTO, previously related to obesity or T2DM, with FLD in HIV-infected patients. METHODS: FLD was defined as a value of the controlled attenuation parameter (CAP) ≥ 238 dB/m, obtained by transient elastography...

BACKGROUND: The sensitivity of cobalt (Co) and chromium (Cr) ion-levels in detecting poorly performing metal-on-metal hip implants is low. This study proposes that serial changes in ion-levels are a more accurate marker of arthroplasties at risk. METHODS: Serial metal ion-levels and implant data of 285 patients with ASR resurfacing or replacement were studied. Patient and implant characteristics were analysed using univariate and multivariate analyses. RESULTS: 111 (39%) had revision surgery...

Neutrophil granule exocytosis plays an important role in innate and adaptive immune responses. The present study examined TNF-α stimulation or priming of exocytosis of the 4 neutrophil granule subsets. TNF-α stimulated exocytosis of secretory vesicles and gelatinase granules and primed specific and azurophilic granule exocytosis to fMLF stimulation. Both stimulation and priming of exocytosis by TNF-α were dependent on p38 MAPK activity. Bioinformatic analysis of 1115 neutrophil proteins identified by mass spectrometry as being phosphorylated by TNF-α exposure found that actin cytoskeleton regulation was a major biologic function...

Each year millions of Americans present to the emergency department (ED) for care after a motor vehicle collision (MVC); the majority (>90%) are discharged to home after evaluation. Acute musculoskeletal pain is the norm in this population, and such patients are typically discharged to home with prescriptions for oral opioid analgesics or nonsteroidal antiinflammatory drugs (NSAIDs). The influence of acute pain management on subsequent pain outcomes in this common ED population is unknown. We evaluated the effect of opioid analgesics vs NSAIDs initiated from the ED on the presence of moderate to severe musculoskeletal pain and ongoing opioid use at 6 weeks in a large cohort of adult ED patients presenting to the ED after MVC (n = 948)...
