Ye Chen-Izu, Leighton T Izu
The heart has the ability to adjust to changing mechanical loads. The Frank-Starling law and the Anrep effect describe exquisite intrinsic mechanisms the heart has for autoregulating the force of contraction to maintain cardiac output under preload and afterload. Although these mechanisms have been known for more than a century, their cellular and molecular underpinnings are still debated. How does the cardiac myocyte sense a change in preload or afterload? How does the myocyte adjust its response to compensate for such changes? In cardiac myocytes Ca(2+) is a crucial regulator of contractile force and in this review we compare and contrast recent results from different labs that address two important questions...

The use of environmental DNA (eDNA) in biodiversity assessments offers a step-change in sensitivity, throughput and simultaneous measures of ecosystem diversity and function. There remains, however, a need to examine eDNA persistence in the wild through simultaneous temporal measures of eDNA and biota. Here, we use metabarcoding of two markers of different lengths, derived from an annual time series of aqueous lake eDNA to examine temporal shifts in ecosystem biodiversity and in an ecologically important group of macroinvertebrates (Diptera: Chironomidae)...

Daniel Marsden, Rachel Giles
Background People with learning disabilities experience significant inequalities in accessing healthcare. Legal frameworks, such as the Equality Act 2010, are intended to reduce such disparities in care, and require organisations to make 'reasonable adjustments' for people with disabilities, including learning disabilities. However, reasonable adjustments are often not clearly defined or adequately implemented in clinical practice. Aim To examine and synthesise the challenges in caring for people with learning disabilities to develop a framework for making reasonable adjustments for people with learning disabilities in hospital...

Molecular pathological epidemiology (MPE) is a transdisciplinary and relatively new scientific discipline that integrates theory, methods, and resources from epidemiology, pathology, biostatistics, bioinformatics, and computational biology. The underlying objective of MPE research is to better understand the etiology and progression of complex and heterogeneous human diseases with the goal of informing prevention and treatment efforts in population health and clinical medicine. Although MPE research has been commonly applied to investigating breast, lung, and colorectal cancers, its methodology can be used to study most diseases...

BACKGROUND: Net survival is the most common measure of cancer prognosis and has been used to study differentials in cancer survival between ethnic or racial population subgroups. However, net survival ignores competing risks of deaths and so provides incomplete prognostic information for cancer patients, and when comparing survival between populations with different all-cause mortality. Another prognosis measure, "crude probability of death", which takes competing risk of death into account, overcomes this limitation...

OBJECTIVE: Multi-state population-based studies exploring the racial/ethnic differences in the prevalence and correlates of postpartum depression (PPD), which affects 10-20% of women in the US, are rare. The aim of this study was to examine the racial/ethnic disparities in the relationship between antenatal stressful life events and PPD among US women and to explore whether antenatal health care provider communication on perinatal depression was associated with a lower risk. METHODS: Data from the 2009-2011 Pregnancy Risk Assessment Monitoring System (PRAMS) were used...

Disparities exist between Latinos and non-Latino whites in cognitive function. Dance is culturally appropriate and challenges individuals physically and cognitively, yet the impact of regular dancing on cognitive function in older Latinos has not been examined. A two-group pilot trial was employed among inactive, older Latinos. Participants (N = 57) participated in the BAILAMOS(©) dance program or a health education program. Cognitive test scores were converted to z-scores and measures of global cognition and specific domains (executive function, episodic memory, working memory) were derived...

OBJECTIVES: The incidence of and survival from lung cancer are associated with socioeconomic position, and disparities have been observed in both curative and palliative treatment for lung cancer. 'Patient navigation' is valuable in addressing health disparity, with timely treatment and transition to care. We conducted a pilot study to test the feasibility of a patient navigator program (PAtient COach) for newly diagnosed lung cancer. We present the trial, the findings from the pilot study and discuss factors that might have affected recruitment rates...

Endozoicomonas bacteria are globally distributed and often abundantly associated with diverse marine hosts including reef-building corals, yet their function remains unknown. In this study we generated novel Endozoicomonas genomes from single cells and metagenomes obtained directly from the corals Stylophora pistillata, Pocillopora verrucosa, and Acropora humilis. We then compared these culture-independent genomes to existing genomes of bacterial isolates acquired from a sponge, sea slug, and coral to examine the functional landscape of this enigmatic genus...

BACKGROUND: Low socioeconomic status and Medicaid insurance as a primary payer have been associated with major disparities in resource utilization and risk-adjusted outcomes for patients undergoing total joint arthroplasty. With the expansion of Medicaid through the Affordable Care Act in 2014, examination of these disparities has become increasingly relevant for the treatment of proximal humerus fracture (PHF). METHODS: The Healthcare Cost and Utilization Project Nationwide Inpatient Sample database was used to identify patients who were treated for PHF from 2002 to 2012...

Metabolic syndrome is common in mental health consumer populations, and is linked to cardiovascular disease, stroke and diabetes. Metabolic screening is a way of recognising consumers who are at risk of developing metabolic syndrome but internationally screening rates remain low. A retrospective audit was completed at one Australian public mental health service on the case files of 100 randomly selected consumers to determine nurses level of compliance with metabolic screening policies over a 12 month period...

The psychological process of individuation as experienced in Jungian work may lead to states of consciousness that resemble advanced spiritual developments across religious traditions and cultures. This is where Westerners may reach a common ground with the East. In the essentials and with respect to the final goal there is little difference among the many ways to the self, even if the cultural features in the landscape are disparate. In late stage Jungian analysis and individuation and in what Erich Neumann calls 'centroversion', the personal and the impersonal aspects of the personality accumulate around the ego-self axis to form a composite identity...

Introduction While disparities in low birth weight (LBW) incidence by racial/ethnic group are well known, differences in LBW incidence by maternal birthplace within racial/ethnic groups, and particularly, differences after adjustment for pregnancy complications, are less clear. Methods We conducted a population-based study of LBW using 113,760 singleton, live birth records from King County, Washington (2008-2012), a region in the Pacific Northwest with a large immigrant population. Study participants were Asian, non-Hispanic black, Hispanic, Native Hawaiian/Other Pacific Islander (NHOPI), and non-Hispanic white women...

Research indicates that sexual minority youth are disproportionately criminalized in the U.S. and subjected to abusive treatment while in correctional facilities. However, the scope and extent of disparities based on sexual orientation remains largely overlooked in the juvenile justice literature. This study, based on a nationally representative federal agency survey conducted in 2012 (N = 8785; 9.9% girls), reveals that 39.4% of girls and 3.2% of boys in juvenile correctional facilities identified as lesbian, gay, or bisexual...

BACKGROUND: Lower socioeconomic status (SES) and environmental tobacco smoke (ETS) exposure are both associated with poorer disease outcomes in cystic fibrosis (CF), and children with low SES are disproportionately exposed to ETS. We analyzed a large cohort of young children with CF to distinguish the impact of SES and ETS on clinical outcomes. METHODS: The Early Pseudomonas Infection Control Observational study enrolled Pseudomonas-negative young children with CF <13 years of age...

The emergence of evidence-based psychological treatments (EVPTs) is a scientific success story, but unfortunately the application of these empirically supported procedures has been slow to gain ground in treatment-as-usual settings. This Open Forum commentary argues that direct-to-consumer (DTC) marketing, which has worked well in communicating the advantages of various medicines, should perhaps be considered for use in social marketing of EVPTs. DTC marketing of pharmaceuticals is a long-standing advertising strategy in the United States...
