Joostella strains are emerging candidates for biosurfactant production. Here such ability was analyzed for Joostella strain A8 in comparison with Alcanivorax strain A53 and Pseudomonas strain A6, all previously isolated from hydrocarbon enrichment cultures made of polychaete homogenates. In pure cultures Joostella sp. A8 showed the highest stable emulsion percentage (78.33%), hydrophobicity rate (62.67%), and an optimal surface tension reduction during growth in mineral medium supplemented with diesel oil (reduction of about 12mN/m), thus proving to be highly competitive with Alcanivorax and Pseudomonas strains...

A matched case-control study in Quebec, Canada, evaluated consumption of veal liver as a risk factor for campylobacteriosis. Campylobacter was identified in 28 of 97 veal livers collected concurrently from slaughterhouses and retailers. Veal liver was associated with human Campylobacter infection, particularly when consumed undercooked.

Mylène Suzie Michaud, Marilou Gagnon
Mechanical ventilation in the intensive care unit requires the use of medication to reduce pain, discomfort, anxiety, and agitation. An explicit recall refers to the phenomenon where the person remembers the perceptions that occurred under sedation during mechanical ventilation. Severe psychological consequences may occur as a result of an explicit recall. This phenomenon is not well-defined and there is no common language in the literature. A conceptual analysis was carried out using Rodgers' evolutionary method in order to clarify the concept of explicit recall...

OBJECTIVES: The authors sought to investigate the effect of low irrigation flow rate on lesion characteristics and ablation outcomes in a clinicopathological study. BACKGROUND: Irrigated ablation produces deeper lesions compared with nonirrigated ablation, which may not be desirable in the thin-walled posterior left atrium (LA), where collateral esophageal injury is possible. METHODS: Lesions were placed on the smooth posterior right atrium in 20 swine and posterior LA in 60 patients at a maximum power of 20 to 25 W with either: 1) power-controlled ablation at an irrigation flow rate of 17 ml/min (high-flow group 10 swine; n = 40) or 2) temperature-controlled ablation at an irrigation flow rate of 2 ml/min (low-flow group 10 swine; n = 20)...

Traumatic and overuse hip injuries occur frequently in amateur and professional athletes. After clinical assessment, imaging plays an important role in diagnosis and in defining care management of these injuries. Ultrasonography (US) is being increasingly used in assessment of hip injuries because of the wide availability of US machines, the lower cost, and the unique real-time imaging capability, which allows both static and dynamic evaluation as well as guidance of point-of-care interventions such as fluid aspiration and steroid injection...

We thank Dr. Bredemeier for his comments regarding our manuscript on allopurinol dose escalation and mortality. He raises important evidence to consider in support of an interesting hypothesis that dose escalation may be unnecessary for allopurinol's cardiovascular (CV) protection and may actually be related to adverse CV outcomes. While we agree that evidence exists suggesting that low doses of allopurinol may be sufficient for CV protection, we believe that the studies cited highlight a number of areas where knowledge gaps remain which preclude any definitive conclusions about the effect of dose escalation...

Purpose To determine if postmortem computed tomography (CT) and postmortem CT angiography help to detect more lesions than autopsy in postmortem examinations, to evaluate the strengths and weaknesses of each method, and to define their indications. Materials and Methods Postmortem CT angiography was performed on 500 human corpses and followed by conventional autopsy. Nine centers were involved. All CT images were read by an experienced team including one forensic pathologist and one radiologist, blinded to the autopsy results...

BACKGROUND: Obese patients with rheumatoid arthritis (RA) report greater disability in cross-sectional studies. The longitudinal effects of obesity, however, are not well-characterized. We evaluated associations between obesity, weight loss, and worsening of disability in two large registry studies with long-term follow-up. METHODS: This study included patients with RA from the National Data Bank of Rheumatic Diseases (Forward) (N=23,323) and the Veterans Affairs RA (VARA) registry study (N=1,697)...

The mitochondrial calcium uniporter complex (MCUc) was recently characterized in details in metazoans and consists of pore-forming units (MCUs) and regulatory factors that channel calcium (Ca2+ ) ion into the mitochondria. MCUs participate in many stress and developmentally related processes involving Ca2+ . Although multiple homologues of MCUs and one regulatory subunit are usually present in plants, the first functional characterization and contribution to Ca2+ related processes of these proteins have been reported recently...

Inherited bone marrow failure syndromes (IBMFS) are caused by mutations in genes involved in genomic stability. Although they may be recognized by the association of typical clinical features, variable penetrance and expressivity are common, and clinical diagnosis is often challenging. DNAJC21, which is involved in ribosome biogenesis, was recently linked to bone marrow failure. However, the specific phenotype and natural history remain to be defined. We correlate molecular data, phenotype, and clinical history of five unreported affected children and all individuals reported in the literature...

Alzheimer's disease (AD) deaths have increased by 89% since 2000. This alarming trajectory of neurological disease highlights the failure of current best practice. Deteriorating brain fuel supply is the nemesis of intact neurological health. Cerebral hypo-metabolism associated with AD occurs years before onset. Both the ketogenic diet and calorie restriction (fasting) lead to a compensatory rise in ketones to improve energy deficits in the brain derived from cerebral insulin resistance. Two forms of ketone bodies, β-hydroxybutyrate and acetoacetate, fuel the brain during starvation, fasting and strenuous exercise...

The diagnosis of multiple sclerosis (MS) and other demyelinating diseases of the central nervous system is challenging, and although the currently available biological and imaging tools offer considerable support to physicians, these tools often fail to provide a simple and final answer at the time of a first event. Thus, sets of diagnostic criteria have been published and tested on patient cohorts, and are now used in clinical trials and in daily clinical practice. These criteria have evolved over time to take into account physicians' and patients' needs, along with emerging paraclinical tests...

BACKGROUND: Moderate-to-vigorous physical activity (MVPA) and sleep are positively associated with adults' health, while the association with sedentary behaviour (SED) is negative. Light-intensity physical activity (LPA) is emerging as an independent predictor of improved cardiovascular health. The health impacts of each of these factors have been examined in isolation, but interest has increased in associations between health and movement behaviours collectively. DATA AND METHODS: This analysis examines how reallocating time between movement behaviours is associated with obesity and with self-rated general and mental health...

BACKGROUND: Oral immunotherapy to peanut is effective in desensitizing patients but has significant side effects including anaphylaxis and gastro-intestinal symptoms. In most protocols peanut is administered in a vehicle food. OBJECTIVE: In an exclusively adolescent population, we tested a new approach using sealed capsules of peanut (Gastro-Intestinal Delivery Oral Immunotherapy or GIDOIT) in order to bypass the upper gastro-intestinal tract. The primary aim was to assess the efficacy of the oral build-up phase of GIDOIT and the secondary aim to analyse its safety...
