Soft tissue sarcoma (STS) is a rare tumor with more than 50 histologic subtypes. Although treatment outcomes for patients with STS have improved greatly over the past few decades owing to the adoption of a multidisciplinary approach, patients with advanced disease have a poor prognosis. The development of anticancer drugs has been directed toward improving overall survival (OS). Doxorubicin monotherapy is currently the only standard option for the first-line treatment of STS. However, there is no standard therapy for second-line and later treatment at present...

Therapy of hepatitis C has been revolutionized by Direct Antiviral Agents. These drugs are safe and efficacious in all infected patients, including those with advanced, or decompensated cirrhosis, and are currently largely used in such cases in clinical practice worldwide. It was therefore cause of great concern the publication of two reports suggesting that treatment with DAAs could increase the risk of hepatocellular carcinoma in cirrhotic patients, particularly in those receiving antiviral therapy after having been cured for an HCC...

Genome-wide association studies have facilitated the discovery of thousands of loci for hundreds of phenotypes. However, the issue of missing heritability remains unsolved for most complex traits. Locus discovery could be enhanced with both improved power through multi-phenotype analysis (MPA) and use of a wider allele frequency range, including rare variants (RVs). MPA methods for single-variant association have been proposed, but given their low power for RVs, more efficient approaches are required. We propose multi-phenotype analysis of rare variants (MARV), a burden test-based method for RVs extended to the joint analysis of multiple phenotypes through a powerful reverse regression technique...

Animal coloration is influenced by selection pressures associated with communication. During communication, signallers display traits that inform receivers and modify receiver behaviour in ways that benefit signallers. Here, we discuss how selection on signallers to convey different kinds of information influences animal phenotypes and genotypes. Specifically, we address the phenotypic and genetic consequences of communicating three different kinds of information: individual identity, behavioural strategy and quality...

REVIEW
Mary Caswell Stoddard, Mark E Hauber
The coevolutionary interactions between avian brood parasites and their hosts provide a powerful system for investigating the diversity of animal coloration. Specifically, reciprocal selection pressure applied by hosts and brood parasites can give rise to novel forms and functions of animal coloration, which largely differ from those that arise when selection is imposed by predators or mates. In the study of animal colours, avian brood parasite-host dynamics therefore invite special consideration. Rapid advances across disciplines have paved the way for an integrative study of colour and vision in brood parasite-host systems...

Ethical conflicts are recognized as critical aspects in assessing competence in clinical communication. Moreover, pediatrics residents may face more problems, compared to other disciplines; due to the specific characteristics of the age group receiving services as well as the presence of their families. This study has been conducted with the aim of determining the attitude and perspective of pediatric residents toward ethical conflicts in the field of pediatrics. This descriptive, cross-sectional study was carried out on all residents of Tehran University of Medical Sciences (90 residents), selected through census method, in 2014...

With recent advances in motion-sparing techniques in spine surgery, disc nucleus replacement (DNR) has been introduced as a viable method to restore the biomechanical functions of the spine. Several methods of DNR have been proposed in the literature. However, the risk of device migration or extrusion is a major issue that should be addressed for a successful DNR. DNR using a balloon nucleus (BN) filled with pressurized fluid may be capable of reducing such risks while preserving the advantages of DNR. The objective of this study was to investigate the biomechanical functionalities of the human cadaveric lumbar motion segments with a custom made BN filled with saline at internal fluid pressure of 0...

BACKGROUND: Advance directives are a sensitive issue among traditional Chinese people, who usually refrain from mentioning this topic until it is imperative. Medical decisions for cancer patients are made by their families, and these decisions might violate patients' personal will. OBJECTIVES: This study aimed to examine the acceptance of advance directives among Chinese cancer patients and their families and patient participation in this procedure and, finally, to analyze the moral risk involved...

BACKGROUND: Children and adolescents with Juvenile Idiopathic Arthritis (JIA) typically have reduced physical activity level and impaired aerobic and anaerobic exercise capacity when compared to their non-JIA counterparts. Low intensity exercise regimens appear to be safe in children with JIA and may results in improvements in overall physical function. Poor adherence to paediatric rheumatology treatment may lead to negative clinical outcomes and possibly increased disease activity. This includes symptoms such as pain, fatigue, quality of life, longer term outcomes including joint damage, as well as increase of healthcare associated costs...

Given the severe shortage of physicians in Israel, the Ministry of Health issued a decree that offered advanced authority and responsibilities to experienced nurses; thus, the status of the nurse specialist (NS) was created. The role of NS in Israel is truly varied, incorporating many different facets that range from stabilizing to changing the existing palliative care (PC) orders, including those involving dosages and methods of care provision, issuing of repeat prescriptions, suspending drug treatment, and prescribing new drugs for a patient according to a protocol issued by a physician...

Children have been particularly vulnerable to the economic challenges of the past decade, with half (45 to 51%) of children under the age of 18 living in a low-income home and nearly 22% of those living in poverty. Low-income children are overrepresented in a range of statistics on psychosocial maladjustment issues, but their families are less likely than other socioeconomic groups to participate in mental health services and intervention research. Thus, this review asserts that substantive advances in mental health services and intervention research with low income families must move beyond a between-group, deficit-focused perspective to a more nuanced contemplation of how to: 1) Operationalize the "income" in low-income families; 2) Disentangle the interrelationship of low income, race, and ethnicity; and 3) Optimize recruitment, engagement and retention efforts via sensitivity to the culture of low-income status...

Maternal mortality is an important indicator of health in populations around the world. The distribution of maternal mortality ratio globally shows that middle- and low-income countries have ∼99% of the mortality burden. Most countries of Latin America are considered to be middle- or low-income countries, as well as areas of major inequities among the different social classes. Medical problems in pregnancy remain an important cause of morbidity and mortality in this region. Previous data indicate the need for a call to action for adequate diagnosis and care of medical diseases in obstetric care...

The use of Whole-Genome Sequencing (WGS) in clinical settings has brought up a number of controversial scientific and ethical issues. The application of WGS is of particular relevance in neurology, as many conditions are difficult to diagnose. We conducted a worldwide, web-based survey to explore neurologists' views on the benefits of, and concerns regarding, the clinical use of WGS, as well as the resources necessary to implement it. Almost half of the 204 neurologists in the study treated mostly adult patients (48%), while the rest mainly children (37...

Amyotrophic lateral sclerosis (ALS) is not a curable disease, but it is treatable. By definition, much of the care provided to ALS patients is palliative, even though active life-sustaining strategies are available to prolong survival. Healthcare professionals must develop communication skills that help patients cope with the inexorable progression of the disease and the inevitability of death. Symptomatic treatments as well as respiratory insufficiency and nutritional life-sustaining therapies must be regularly evaluated as the disease progresses, without losing sight of the burden placed on the patient's non-professional caregivers...

PurposeLynch syndrome cases are underidentified, and universal colorectal cancer tumor screening for Lynch syndrome (UTS) has been recommended. UTS implementation is challenging and few successful examples exist to date, and colorectal cancer patients and at-risk family members exhibit low uptake of genetic services. This study sought to identify the elements that could guide the choice of specialties to implement UTS through three main stages: initiating the screen, returning positive screen results, and providing follow-up...

SIGNIFICANCE Cellular senescence, characterized by a permanent cell cycle arrest, has been extensively studied in mitotic cells such as fibroblasts. However, senescent cells have also been observed in the brain. Even though it is recognized that cellular energetic metabolism and redox homeostasis are perturbed in the aged brain and neurodegenerative diseases, it is still unknown which alterations in the overall physiology can stimulate cellular senescence induction and their relationship with the former events...
