Whole-Body (18) FDG-PET in an Arthritis Paraneoplastic Syndrome Revealed an Underlying Hematological Neoplasm.

We showed the first image of (18)FDG-PET, which leads to a diagnosis of lymphoma in an atypical polyarthritis. About 4% of patients with lymphoma or leukemia suffered from rheumatologic paraneoplastic symptoms like arthralgia and about 10% of the patients with rheumatologic or neurologic clinical symptoms develop a solid cancer or hematological neoplasm. (18)FDG-PET is an interesting exam to identify an underlying malignancy when a paraneoplastic syndrome is suspected; it can detect the primitive lesion and/or the metastasis lesions.

Male primary retroperitoneal mucinous cystadenoma.

Primary retroperitoneal mucinous cystadenoma of borderline malignancy is a rare disease, especially in male patients. Often these tumors are not incidentally found due to abdominal symptoms. We present the radiologic abdominal computed tomography scan, surgical, and pathologic images of this unique, rare condition in a male patient.

[Humanitarian medicine as a model for humanitarian action].

Humanitarian action is undergoing profound changes. Beyond the emergency relief phase, it is becoming involved in the processes that enable victims to regain their autonomy and, more recently, in prevention and risk-reduction policies. This trend is similar to that experienced by humanitarian medicine which, after focusing on emergency situations, is now involved in rehabilitation and prevention programs.

Pediatric emergency nurses' self-reported medication safety practices.

Preventable adverse events occur more frequently in areas such as the emergency department with medication errors as the most frequently reported errors. A cross-sectional survey design was used to gather descriptive data of medication safety practices used by pediatric emergency nurses in the Midwest U.S.

[Conclusion: Learning to live together again].

In the face of increasing individualism, the social links which hold our society together could eventually disintegrate. Specific case studies of the summer 2003 heat wave, as well as mental illnesses, addictions, Alzheimer's disease, prisoners and migrants can offer solutions to help tackle solitude. Voluntary associations can play a key role.

On the use of amine-borane complexes to synthesize iron nanoparticles.

The effectiveness of amine-borane as reducing agent for the synthesis of iron nanoparticles has been investigated. Large (2-4 nm) Fe nanoparticles were obtained from [Fe{N(SiMe3)2}2]. Inclusion of boron in the nanoparticles is clearly evidenced by extended X-ray absorption fine structure spectroscopy and Mössbauer spectrometry.

Volatile fingerprints of cancer specific genetic mutations.

Unlabelled: We report on a new concept for profiling genetic mutations of (lung) cancer cells, based on the detection of patterns of volatile organic compounds (VOCs) emitted from cell membranes, using an array of nanomaterial-based sensors. In this in-vitro pilot study we have derived a volatile fingerprint assay for representative genetic mutations in cancer cells that are known to be associated with targeted cancer therapy. Five VOCs were associated with the studied oncogenes, using complementary chemical analysis, and were discussed in terms of possible metabolic pathways.

Development of bi-metallic Fe-Bi nanocomposites: synthesis and characterization.

We investigate the formation of bi-metallic particles in the Fe-Bi system, well known as totally immiscible in the bulk, using a large combination of structural and element-sensitive techniques, well-adapted to the nanoscale. The synthesis approach makes use of the kinetics of decomposition of the different precursors to achieve a controlled sequential growth of the different elements. Different ligands have also been used in order to limit the size and ensure dispersion of the synthesized particles.

MR imaging of the yucatan pig head and neck vasculature.

Purpose: To evaluate the cerebral venous drainage system of the swine as a probable model to test whether extracranial venous abnormalities may play a role in neurodegenerative diseases as reported recently in multiple sclerosis.

Materials And Methods: Three Yucatan micropigs, 5 to 7 months old, were scanned with a comprehensive MRI protocol at 3 Tesla. The vascular anatomy of the head and neck was imaged using conventional and angiographic MR sequences.

Caring in pediatric emergency nursing.

An environment committed to providing family-centered care to children must be aware of the nurse caring behaviors important to parents of children. This descriptive study assessed the psychometrics of a revised version of the Caring Behaviors Assessment (CBA) and examined nurse caring behaviors identified as important to the parents of pediatric patients in a pediatric emergency department. Jean Watson's theory of human caring provided the study's theoretical underpinnings.

TCF7L2 genetic variants modulate the effect of dietary fat intake on changes in body composition during a weight-loss intervention.

Background: TCF7L2 gene variants have been associated with increased risk of type 2 diabetes and higher adiposity. Observational studies and short-term trials have suggested that macronutrients may modify these effects. However, to our knowledge, this has yet to be verified in long-term interventions.

Non-invasive breath analysis of pulmonary nodules.

Introduction: The search for non-invasive diagnostic methods of lung cancer (LC) has led to new avenues of research, including the exploration of the exhaled breath. Previous studies have shown that LC can, in principle, be detected through exhaled-breath analysis. This study evaluated the potential of exhaled-breath analysis for the distinction of benign and malignant pulmonary nodules (PNs).

A symposium and workshop report from the Global Nutrition and Epidemiologic Transition Initiative: nutrition transition and the global burden of type 2 diabetes.

The present report summarises the symposium 'Nutrition Transition and the Global Burden of Type 2 Diabetes' and a workshop on strategies for dietary interventions to prevent type 2 diabetes held by the Global Nutrition and Epidemiologic Transition Initiative, Boston, MA, USA in November 2011. The objectives of this event were to bring attention to the global epidemic of type 2 diabetes in light of the ongoing nutrition transition worldwide, especially in low- and middle-income countries, and to highlight the present evidence on key dietary risk factors contributing to the global diabetes burden. The meeting put forward ideas for further research on this topic and discussed practical recommendations to design and implement culturally appropriate dietary interventions with a focus on improving carbohydrate quality to help alleviate this growing health problem.

Humanity and human DNA.

Genetics has marked the second half of the 20th century by addressing such formidable problems as the identification of our genes and their role, their interaction with the environment, and even their therapeutic uses. The identification of genes raises questions about differences between humans and non-humans, as well as about the evolution towards trans-humanism and post-humanism. In practise, however, the main question concerns the limits of prenatal genetic diagnosis, not only on account of the seriousness of the affections involved but also because of the choice to be made between following-up the medical indication and engaging in a systematic public health strategy aimed at eliminating children with certain handicaps.

Substituting homemade fruit juice for sugar-sweetened beverages is associated with lower odds of metabolic syndrome among Hispanic adults.

Consumption of sugar-sweetened beverages (SSB) has been associated with metabolic syndrome (MetS); however, studies conducted on Hispanic adults are scarce. To determine the association between beverages consumed by Hispanic adults and MetS and its components, data were analyzed in 1872 Costa Rican adults who served as controls of a population-based, case-control study of coronary heart disease. Multivariate-adjusted means were calculated for components of MetS by servings (never, ≤ 1/wk; 2-6/wk, ≥ 1/d) of 2 traditional fruit-based beverages ("fresco" and freshly-squeezed homemade fruit juice, separately) and 2 SSB (instant drinks and regular sodas, separately and combined).

Association between commercial and traditional sugar-sweetened beverages and measures of adiposity in Costa Rica.

Objective: Increasing trends in the consumption of commercial sugar-sweetened beverages (SSB) have occurred in parallel with rising levels of obesity in Latin America, but data showing the relationship between these SSB and obesity are limited. The current study examined the association between commercial and traditional SSB and measures of adiposity in Costa Rica.

Design: A cross-sectional analysis was conducted in which the exposure, SSB intake, was defined as frequency of daily servings of 'fresco' (a traditional home-made beverage), fruit drink (commercially available SSB), soda and fruit juice (made from fruits at home).

Impact of malnutrition and social determinants on survival of HIV-infected adults starting antiretroviral therapy in resource-limited settings.

Objectives: Determining the impact of malnutrition, anaemia and social determinants on survival once starting antiretroviral therapy (ART) in a cohort of HIV-infected adults in a rural HIV care centre in Sihanoukville, Cambodia.

Methods: Retrospective and descriptive cohort study of adults starting ART between December 2004 and July 2009. We used the Kaplan-Meier and Cox regression survival analyses to identify predictors of death.

[Study of treatment adherence by patients living with HIV in 2009 at the outpatient care and treatment center of Brazzaville, Congo].

Objectives: The purpose of this study was to evaluate treatment adherence and its determinants in patients living with HIV followed up at the outpatient care and treatment center in Brazzaville, Congo.

Methods: This cross-sectional study included patients who attended the center from July to October 2009. Adherence was evaluated using a self-administered questionnaire, 5 distinct measurement tools, and global adherence index.

A meat, processed meat, and French fries dietary pattern is associated with high allostatic load in Puerto Rican older adults.

Background: Consumption of certain dietary patterns, such as a Western diet, has been associated with unfavorable physiologic outcomes. Diet has been proposed as a contributor to allostatic load, a composite measure of physiological dysregulation.

Objective: To determine the association of dietary patterns, defined by "meat and french fries," "traditional Puerto Rican foods" (rice, beans, and oils), or "sweets," with allostatic load, and with the 10 individual physiologic parameters that comprise it.

A higher ratio of beans to white rice is associated with lower cardiometabolic risk factors in Costa Rican adults.

Background: A high intake of white rice is associated with the metabolic syndrome and type 2 diabetes. Costa Ricans follow a staple dietary pattern that includes white rice and beans, yet the combined role of these foods on cardiometabolic risk factors has not been studied.

Objective: We aimed to determine the association between intake of white rice and beans and the metabolic syndrome and its components in Costa Rican adults (n = 1879) without diabetes.

Autonomic dysfunction in 2009 pandemic influenza A (H1N1) virus-related infection: a pediatric comparative study.

Background: Relationship between respiratory morbidity and influenza virus has been well-documented in infants, whatever their age. However, in spite of severe cardiac and respiratory events of central origin, autonomic dysfunction potentially induced by this virus is poorly understood. We thus explored the autonomic nervous system (ANS) profile of infected infants during the 2009 pandemic influenza disease.

[Decision-making in termination of pregnancy: a French perspective].

Objective: To evaluate the caregivers' opinions regarding decision-making in termination of pregnancy (TOP) for fetal anomaly.

Material And Methods: Questionnaire survey using a semi-structured survey based on visual analogue scales, sent to all multidisciplinary centres for prenatal diagnosis in France. Answers were received from 26 centres nation-wide.

[Lyme uveitis: 2 case reports].

Lyme borreliosis is a zoonosis characterized by great clinical polymorphism. We report 2 cases in patients who presented ocular manifestations: one anterior uveitis in an adult, which resolved under treatment, and one posterior uveitis in a child, whose initial ophthalmologic examination already showed retinal fibrous scars including the macular area. Lyme disease is on the long list of causes that must be discussed in cases of uveitis.
