Ashutosh Mukherji, Mourougan Sinnatamby
PURPOSE: Soft tissue sarcomas of the extremities account for half of all soft tissue sarcomas. Radiotherapy and surgery have been the standard modalities in the treatment of this type of cancer. Brachytherapy can be used as the sole therapy, if the target volume is localized and easily accessible. This work reports three cases of shoulder soft tissue sarcomas with positive deep resected margins, treated with a combination of external beam radiotherapy and surface mould brachytherapy boost technique...

BACKGROUND & AIMS: Nutrition support teams (NSTs) are important and unique entities in acute care hospitals. Despite their utility, NSTs are lacking in the majority of hospitals worldwide and where they exist, most members only spend a fraction of their time working within that role. We aim to evaluate the effect of protected time on NST performance by assessing the influence of structure and process in NST activities. METHODS: All large public hospitals (>250 beds) in the Brazilian Federal District were evaluated with a structured questionnaire designed to assess NST performance...

Hadiseh Mahdavi, Javier Rosell-Ferrer
SIGNIFICANCE: Unobtrusive vital signs monitoring is of major importance for various medical areas such as detection and treatment of sleep disorders, monitoring neonates and burned victims, home health care and smart home applications and wearables among others. Such applications call for monitoring methods in which the patient's natural state is less interfered with. An ideal device would be non-invasive, minimally restrictive, robust enough to compensate movements of the patients, and would operate without relying on the patient's full cooperation...

BACKGROUND: Many hospitals use rapid response teams (RRTs) to respond to deteriorating patients, but it remains unclear what organizations actually monitor. Understanding what organizations value in an RRT may help clarify measurement choices. Interviews were conducted to determine how organizational leaders perceived and evaluated their hospitals' RRTs. METHODS: The study used a descriptive, qualitative design. Participants were nurse executives and key informants in 300- to 500-bed hospitals in the south-central United States and were recruited using purposive and snowball sampling...

BACKGROUND AND PURPOSE: There are no significant differences in outcomes between patients receiving inpatient and day-case lumbar microdiscectomy, but the latter is still underused in the NHS. Here we aimed to identify factors contributing to successful same-day discharge in day-case patients. METHODS: This was a retrospective observational study of patients undergoing elective lumbar microdiscectomy between August 2012 and December 2014. Age, gender, day of surgery, distance to hospital, ASA grade, regular opiate use, smoking status, order on the operating list, and side and level of surgery were examined by logistic regression to assess their influence on same-day discharge...

The involvement of purinergic signaling in several brain functions has been recognized, but the modulation on maternal behavior by the purinergic system is not established, even though there are functional interactions between the purinergic and oxytocinergic systems. Therefore, the aim of our study was to investigate whether central administration of P2 receptor antagonists affected the maternal behavior of lactating rats and c-Fos immunoreactivity in the forebrain. On day 7 of lactation, female rats were treated with vehicle (5μL; i...

Necrosis culminates in spilling cellular content through the permeabilized plasma membrane, thereby releasing potentially immunostimulatory molecules in the pericellular space of dead cells. Accordingly, molecules involved in necroptotic signaling, such as receptor-interacting serine/threonine-protein kinase 3 (RIPK3) and mixed lineage kinase-like (MLKL) have been found to stimulate anticancer immune responses in mouse models of chemotherapy. mRNAs encoding prominent pro-necrotic gene products (RIPK1, RIPK3, MLKL, PGAM5 and DFNA5) were correlated with immune-related metagenes in several cancer types (breast, colorectal, lung, ovary, melanoma), revealing the strongest associations in breast cancer...

Studies investigating the feasibility of new, or improved, biotechnologies, such as wastewater treatment digesters, inevitably start with laboratory-scale trials. However, it is rarely determined whether laboratory-scale results reflect full-scale performance or microbial ecology. The Expanded Granular Sludge Bed (EGSB) bioreactor, which is a high-rate anaerobic digester configuration, was used as a model to address that knowledge gap in this study. Two laboratory-scale idealizations of the EGSB-a one-dimensional and a three- dimensional scale-down of a full-scale design-were built and operated in triplicate under near-identical conditions to a full-scale EGSB...

The patients with non-small cell lung cancer (NSCLC) treated with definitive conformal radiotherapy (RT) were evaluated in terms of side effects and survival. Normal tissue complication probability (NTCP) was calculated for 68 patients treated between 2009 and 2012. Clinical and dosimetric factors were analyzed. The median dose of 63 Gy (range: 54 to 70 Gy) was given with conformal RT with blocks (n = 37), 3-dimensional conformal RT (3DCRT) (n = 11), or intensity-modulated RT (IMRT) (n = 20)...

BACKGROUND: Gastric cancer is a common cancer with a poor prognosis. Chemokines play important roles in the tumor microenvironments to support tumor growth and metastasis. The effects of C-C motif chemokine ligand 22 (CCL22) in gastric cancer remain unclear. MATERIALS AND METHODS: Between January 1, 2014 and April 31, 2014, a total of 298 gastric cancer patients were recruited to this study. Circulating concentrations of CCL22 were measured in gastric cancer patients before surgery, at discharged and during follow-up visits...

REVIEW
Jill Maria Wecht, William A Bauman
Neural output from the sympathetic and parasympathetic branches of the autonomic nervous system (ANS) are integrated to appropriately control cardiovascular responses during routine activities of daily living including orthostatic positioning. Sympathetic control of the upper extremity vasculature and the heart arises from the thoracic cord between T1 and T5, whereas splanchnic bed and lower extremity vasculature receive sympathetic neural input from the lower cord between segments T5 and L2. Although the vasculature is not directly innervated by the parasympathetic nervous system, the SA node is innervated by post-ganglionic vagal nerve fibers via cranial nerve X...

Stressors clearly contribute to addiction etiology and relapse in humans, but our understanding of specific mechanisms remains limited. Rodent models of addiction offer the power, flexibility, and precision necessary to delineate the causal role and specific mechanisms through which stressors influence alcohol and other drug use. This review describes a program of research using startle potentiation to unpredictable stressors that is well positioned to translate between animal models and clinical research with humans on stress neuroadaptations in addiction...
