REVIEW
John Tayu Lee, Kenny D Lawson, Yizhou Wan, Azeem Majeed, Stephen Morris, Michael Soljak, Christopher Millett
The World Health Organization recommends that countries implement population-wide cardiovascular disease (CVD) risk assessment and management programmes. The aim of this study was to conduct a systematic review to evaluate whether this recommendation is supported by cost-effectiveness evidence. Published economic evaluations were identified via electronic medical and social science databases (including Medline, Web of Science, and the NHS Economic Evaluation Database) from inception to March 2016. Study quality was evaluated using a modified version of the Consolidated Health Economic Evaluation Reporting Standards...

REVIEW
Jagan A Pillai, James B Leverenz
Sleep abnormalities are clearly recognized as distinct clinical symptom of concern in neurodegenerative disorders. Appropriate management of sleep related symptoms has a positive impact on the quality of life of patients with neurodegenerative disorders. This review provides an overview of mechanisms that are currently being considered that tie sleep with neurodegeneration. It appraises the literature regarding specific sleep changes among common neurodegenerative diseases with a focus on Alzheimer's disease and synucleinopathies (i...

BACKGROUND: Across cancers, the decision to pursue genetic testing is influenced more by subjective than objective factors. However, skin cancer, which is more prevalent, visual, and multifactorial than many other malignancies, may offer different motivations for pursuing such testing. OBJECTIVES: The primary objective was to determine factors influencing the decision to receive genetic testing for skin cancer risk. A secondary objective was to assess the impact of priming with health questions on the decision to receive testing...

BACKGROUND: Community-dwelling consumers of healthcare are increasing, many aging with life-limiting conditions and deteriorating cognition. However, few have had advance care planning discussions or completed documentation to ensure future care preferences are acted upon. This study examines the awareness, attitudes, and experiences of advance care planning amongst older people and unrelated offspring/caregivers of older people residing in the community. METHODS: Qualitative descriptive research, which included focus groups with older people (55+ years) and older people's offspring/caregivers living in an Australian city and surrounding rural region...

Circulating cell-free DNA (cfDNA) has been considered an interesting diagnostic/prognostic plasma biomarker in tumor-bearing subjects. In cancer patients, cfDNA can hypothetically derive from tumor necrosis/apoptosis, lysed circulating cells, and some yet unrevealed mechanisms of active release. This study aimed to preliminarily analyze cfDNA in dogs with canine mammary tumors (CMTs). Forty-four neoplastic, 17 non-neoplastic disease-bearing, and 15 healthy dogs were recruited. Necrosis and apoptosis were also assessed as potential source of cfDNA on 78 CMTs diagnosed from the 44 dogs...

Controlled human malaria infection (CHMI) in healthy human volunteers is an important and powerful tool in clinical malaria vaccine development. However, power calculations are essential to obtain meaningful estimates of protective efficacy, while minimizing the risk of adverse events. To optimize power calculations for CHMI-based malaria vaccine trials, we developed a novel non-linear statistical model for parasite kinetics as measured by qPCR, using data from mosquito-based CHMI experiments in 57 individuals...

Fungal diseases are major threats to the most important crops upon which humanity depends. Were there to be a major epidemic that severely reduced yields, its effects would spread throughout the globalized food system. To explore these ramifications, we use a partial equilibrium economic model of the global food system (IMPACT) to study a hypothetical severe but short-lived epidemic that reduces rice yields in the countries affected by 80%. We modelled a succession of epidemic scenarios of increasing severity, starting with the disease in a single country in southeast Asia and ending with the pathogen present in most of eastern Asia...

Hatred of terrorists is an obstacle to the implementation of effective counterterrorism policies-it invites indiscriminate retaliation, whereas many of the greatest successes in counterterrorism have come from understanding terrorists' personal and political motivations. Drawing from psychological research, traditional prejudice reduction strategies are generally not well suited to the task of reducing hatred of terrorists. Instead, in 2 studies, we explored education's potential ability to reduce extreme negative attitudes toward terrorists...

RATIONALE: Drug-induced valvular heart disease (DI-VHD) remains an under-recognized entity. PATIENT CONCERNS: This report describes a heart valve replacement which was complicated by intractable systemic pulmonary arterial hypertension in a 61-year-old female with severe restrictive mitral and aortic disease. The diagnosis of valvular disease was preceded by a history of unexplained respiratory distress. The patient had been exposed to benfluorex for 6.5 years. DIAGNOSES: The diagnostic procedure documented specific drug-induced valvular fibrosis...

Interleukin-32 gamma (IL-32γ) is a recently discovered cytokine that is elevated in inflamed tissues and contributes to pathogenic features of bone in human inflammatory rheumatic diseases. Nevertheless, the role of IL-32γ and its direct involvement in bone metabolism is unclear. We investigated the molecular mechanism of IL-32γ in bone remodeling and the hypothetical correlation between IL-32γ and disease activity in osteoporosis patients. Transgenic (TG) mice overexpressing human IL-32γ showed reduced bone loss with advancing age, increased bone formation, and high osteogenic capacity of osteoblast compared to wild-type (WT) mice through the upregulation of miR-29a, which caused a reduction of Dickkopf-1 (DKK1) expression...

#11
REVIEW
Bart Dingenen, Alli Gokeler
Athletes who have sustained an anterior cruciate ligament (ACL) injury often opt for an ACL reconstruction (ACLR) with the goal and expectation to resume sports. Unfortunately, the proportion of athletes successfully returning to sport is relatively low, while the rate of second ACL injury has been reported to exceed 20% after clearance to return to sport, especially within younger athletic populations. Despite the development of return-to-sport guidelines over recent years, there are still more questions than answers on the most optimal return-to-sport criteria after ACLR...

BACKGROUND: Appendectomy is the most common emergency surgery performed in the USA. Removal of a non-inflamed appendix during unrelated abdominal surgery (prophylactic or incidental appendectomy) can prevent the downstream risks and costs of appendicitis. It is unknown whether such a strategy could be cost saving for the health system. METHODS: We considered hypothetical patient cohorts of varying ages from 18 to 80, undergoing elective laparoscopic abdominal and pelvic procedures...

John Rawls posited that we could determine the nature of justice if we imagined ourselves observing conditions in society from behind a hypothetical "veil of ignorance." Not knowing how or where we would end up-rich, poor, empowered, disabled-we would choose governing principles that did not leave one disadvantaged because of his or her circumstances. Rawls's concepts are implicitly embedded in the Affordable Care Act, which guarantees that vastly more Americans can obtain health insurance. The law effectively closed down the de facto lottery that awarded coverage to most but left out millions of others...

The plant pathogen Pseudomonas syringae accounts for substantial crop losses and is considered an important agricultural issue. To better manage disease in the field, it is important to have an understanding of the underlying genetic mechanisms that mediate virulence. There are a substantial number of genes in sequenced bacterial genomes, including P. syringae, that encode for conserved hypothetical proteins; some of these have been functionally characterized in other Pseudomonads and have been demonstrated to play important roles in disease...

L Pinto, M Mateus, A Silva
The prediction of the path of harmful algal blooms (HABs) along the coast can be achieved using numerical models of ocean circulation in order to reproduce the hydrodynamics of the study area. With this setting, our work aimed at the (1) study of key past events to evaluate the model ability to reproduce the transport pathways of blooms along the Iberian coast, and (2) to assess the relevance of such strictly physical approach. The simulations described here rely on the advection of lagrangian elements after a point release in a hypothetical location for bloom initiation, and the subsequent assessment of the influence of the surface currents transport on the extent of the bloom...

The U.S. Preventive Services Task Force (USPSTF) recently updated their national lung screening guidelines and recommended low-dose computed tomography (LDCT) for lung cancer (LC) screening through age 80. However, the risk of overdiagnosis among older populations is a concern. Using four comparative models from the Cancer Intervention and Surveillance Modeling Network, we evaluate the overdiagnosis of the screening program recommended by USPSTF in the U.S. 1950 birth cohort. We estimate the number of LC deaths averted by screening (D) per overdiagnosed case (O), yielding the ratio D/O, to quantify the trade-off between the harms and benefits of LDCT...

Single-ion magnets (SIMs) that can maintain magnetization direction on an individual transition metal atom represent the smallest atomic-scale units for future magnetic data storage devices and molecular electronics. Here we present a robust extended inorganic solid hosting efficient SIM centers, as an alternative to molecular SIM crystals. We show that unique dioxocobaltate(II) ions, confined in the channels of strontium hydroxyapatite, exhibit classical SIM features with a large energy barrier for magnetization reversal (Ueff) of 51-59 cm(-1)...

Alexander Jules Bourque, C Rebecca Locker, Gregory C Rutledge
Heterogeneous nucleation refers to the propensity for phase transformations to initiate preferentially on foreign surfaces, such as vessel walls, dust particles or formulation additives. In crystallization, the form of the initial nucleus has ramifications for the crystallographic form, morphology and properties of the resulting solid. Nevertheless, the discovery and design of nucleating agents remains a matter of trial and error, due to the very small spatio-temporal scales over which formation of the critical nucleus occurs, and the extreme difficulty of examining such events empirically...

OBJECTIVES: The Crohn's Disease Endoscopic Index of Severity (CDEIS) and the Simple Endoscopic Score for Crohn's Disease (SES-CD) are commonly used to assess Crohn's disease (CD) activity; however neither instrument is fully validated. We evaluated the responsiveness to change of the SES-CD and CDEIS using data from a trial of adalimumab, a drug therapy of known efficacy. METHODS: Paired video recordings (N=112) of colonoscopies (baseline and week 8-12) obtained from patients with CD who participated in a trial of adalimumab therapy were reviewed in random order, in duplicate, by four central readers (56 pairs of videos by 2 groups of readers)...

EDITORIAL
Shlomit Strulov Shachar, Grant R Williams
Body mass index (BMI) and simple counts of weight are easy and available tools in the clinic and in research. Recent studies have shown that cancer patients with a low normal BMI (or those with weight loss) have worse outcomes than obese patients. These results suggest that obesity has a protective effect and has been termed the "obesity paradox." In this commentary, we discuss hypothetical explanations and take a step beyond BMI or simple weights alone to present other useful and more specific body composition metrics, such as muscle tissue mass, visceral fat mass, and subcutaneous fat mass...
