Although no internationally accepted consensus definition exists, lipids can be broadly defined as "fatty acids and their derivatives, and substances related biosynthetically or functionally to these compounds". Lipids play critical roles as (i) the major structural components of biological membranes, and as functional and regulatory components of membrane protein signaling, (ii) bioactive intra- and inter-cellular signaling molecules, and (iii) energy storage molecules for the maintenance of energy homeostasis...

BACKGROUND: Regular consumption of sugar sweetened beverages (SSBs) is associated with weight gain, type 2 diabetes, and dental caries. The UK will introduce a levy on the manufacturers of SSBs in 2018. Details will be negotiated over the next two years. How the UK public views SSB taxes is likely to be an important determinant of the content and success of the final policy. We aimed to capture the views, ideas and concerns of commenters on major UK news websites on SSB taxes. METHODS AND FINDINGS: We conducted a qualitative analysis of reader comments to online news coverage of one proposal for an SSB tax in the UK...

BACKGROUND: Skeletal muscle spasticity is a major physical complication resulting from traumatic brain injury (TBI), which can lead to muscle contracture, joint stiffness, reduced range of movement, broken skin and pain. Treatments for spasticity include a range of pharmacological and non-pharmacological interventions, often used in combination. Management of spasticity following TBI varies from other clinical populations because of the added complexity of behavioural and cognitive issues associated with TBI...

Performance-based financing (PBF) is assumed to improve health care delivery by motivating health workers to enhance their work performance. However, the exact motivational mechanisms through which PBF is assumed to produce such changes are poorly understood to date. Although PBF is increasingly recognized as a complex health systems intervention, its motivational effect for individual health workers is still often reduced to financial 'carrots and sticks' in the literature and discourse. Aiming to contribute to the development of a more comprehensive understanding of the motivational mechanisms, we explored how PBF impacted health worker motivation in the context of the Malawian Results-based Financing for Maternal and Newborn Health (RBF4MNH) Initiative...

As Japan becomes a super-aging society, presentation of the best ways to provide medical care for the elderly, and the direction of that care, are important national issues. Elderly people have multi-morbidity with numerous medical conditions and use many medical resources for complex treatment patterns. This increases the likelihood of inappropriate medical practices and an evidence-practice gap. The present study aimed to: derive findings that are applicable to policy from an elucidation of the actual state of medical care for the elderly; establish a foundation for the utilization of National Database of Health Insurance Claims and Specific Health Checkups of Japan (NDB), and present measures for the utilization of existing databases in parallel with NDB validation...

Alzheimer's disease (AD) belongs to one of the most multifactorial, complex and heterogeneous morbidity-leading disorders. Despite the extensive research in the field, AD pathogenesis is still at some extend obscure. Mechanisms linking AD with certain comorbidities, namely diabetes mellitus, obesity and dyslipidemia, are increasingly gaining importance, mainly due to their potential role in promoting AD development and exacerbation. Their exact cognitive impairment trajectories, however, remain to be fully elucidated...

Adolescents with ASD face numerous personal and contextual barriers that impede the development of social motivation and core competencies, warranting the need for targeted intervention. A randomized controlled trial was conducted with 40 adolescents to evaluate the merits of a multi-component socialization intervention that places emphasis on experiential learning. This investigation evaluated the impact of the 20-week START program on the social functioning of adolescents with ASD. Significant Group × Time differences between START and waitlist control groups were found across multiple measures...

Viral latency is a major barrier to curing HIV infection with antiretroviral therapy, and consequently, for eliminating the disease globally. The establishment, maintenance, and potential clearance of latent infection are complex dynamic processes and can be best understood and described with the help of mathematical models. Here we review the use of viral dynamics models for HIV, with a focus on applications to the latent reservoir. Such models have been used to explain the multiphasic decay of viral load during antiretroviral therapy, the early seeding of the latent reservoir during acute infection and the limited inflow during treatment, the dynamics of viral blips, and the phenomenon of posttreatment control...

Autophagy and inflammasome complex assembly are physiological processes that control homeostasis, inflammation, and immunity. Autophagy is a ubiquitous pathway that degrades cytosolic macromolecules or organelles, as well as intracellular pathogens. Inflammasomes are multi-protein complexes that assemble in the cytosol of cells upon detection of pathogen- or danger-associated molecular patterns. A critical outcome of inflammasome assembly is the activation of the serine protease caspase-1, which activates the pro-inflammatory cytokine precursors pro-IL-1β and pro-IL-18...

The prevalence of metabolic syndrome is increasing worldwide and has become a risk factor for the development of chronic kidney disease. The complex linkage between metabolic syndrome and chronic kidney disease is under research and the factors involved beyond the biological pathogenesis include demographic, sociological and psychological factors that are related to the metabolic syndrome prevalence. The social context of disease causation is as relevant to today's clinical scientist and practitioner as biomarker-directed risk stratification and therapy...

Medication adherence is a complex, multi-determined behavior that is often influenced by system- (e.g., cost), drug- (e.g., regimen complexity), and patient-related (e.g., depression) factors. System-level approaches (e.g., making medications more affordable) are critically important but do not address patient-level factors that can undermine adherence. In this paper, we identify patient-level determinants of non-adherence and discuss whether mindfulness-training approaches that target these determinants can help to improve adherence to medical treatment...

INTRODUCTION: Spondylopelvic dissociation is an uncommon and complex injury that results from high-energy trauma with axial overloading through the sacrum. Due to the life-threatening nature of these injuries, standard Advanced Trauma Life Support(®) (ATLS) protocol must be used in the trauma setting as part of the initial management of these patients. The key to diagnosis is a good physical exam coupled with high level of suspicion. Radicular neurological deficits commonly are present in spondylopelvic dissociation (L5's roots) and should be documented for future evaluations...

High-definition fluoroscopic imaging is required to perform endovascular procedures safely and precisely, especially in complex cases, resulting in longer procedures and increased radiation exposure. This is of importance for training institutions as trainees, even with sound instruction in as low as reasonably achievable (ALARA) principles, tend to have high radiation exposures. Recently, there was an upgrade in the imaging system allowing for comparison of radiation exposure to patients and providers. We performed an analysis of consecutive endovascular aneurysm repair (EVAR) and superficial femoral artery (SFA) interventions in the years 2013 to 2014...

There is a consistent relationship between physical activity, physical fitness, and health across almost all clinical contexts, including the perioperative setting. Physiological measurements obtained during physical exercise may be used to infer the risk of adverse outcome after major surgery. In particular, data obtained from perioperative cardiopulmonary exercise testing have an expanding role in perioperative care. Such information may be used to inform a variety of changes in clinical practice, including interventions that may reduce the risk of perioperative adverse events...

In an era when healthcare has become increasingly complex and patient expectations are higher than ever before, we can find the decision-making process for patients, potentially at the end of their lives, increasingly difficult. In the shift from paternalism to patient choice, we can struggle to know what to do when faced with a patient, their family, or both requesting or demanding inadvisable, inappropriate, or futile treatments. It can feel as if we are being asked to subject patients to intrusions and interventions that 'just feel wrong'...

Human beings who work in complex, dynamic, and stressful situations make mistakes. This is as true for anaesthetists as for any other health-care professional, but we face unique challenges in the many roles and responsibilities we have in diverse clinical contexts. As a profession, we are well versed in the development and utilization of improvement techniques and technologies that prioritize high-quality, safe care for patients. This article focuses on one particular domain of patient safety in which anaesthetists have been pre-eminent, the use of simulation in training to improve both professional capabilities and patient safety in anaesthetic practice...

BACKGROUND: Traumatic thoracoabdominal injuries can involve multiple organs and multiple cavities, which increases the complexity of surgical management. Traditionally, these injuries required laparotomy and thoracotomy. However, minimally invasive intervention may be reasonable for stable patients. MATERIALS AND METHODS: We present a case of a thoracoabdominal gunshot wound resulting in multiorgan, multicavity injury to the lung, diaphragm, and liver. We performed hepatorrhaphy and diaphragm repair, and addressed a retained hemothorax through a transabdominal laparoscopic approach...

BACKGROUND: Increasing rates of marijuana use and high rates of depression among females are major public health concerns and ambiguous study results suggest a complex association between the two. Inconsistent findings may be due to differences in sample characteristics (e.g., females vs. males) and result from differences in the relationship over time (i.e., across developmental stages). OBJECTIVES: Presently, the extent to which the relationship between depression and marijuana use differed for females in emerging adulthood, compared to young adult females, was examined...
