Although the clinical landscape of melanoma is improving rapidly, metastatic melanoma remains a deadly disease. Age remains one of the greatest risk factors for melanoma, and patients older than 55 have a much poorer prognosis than younger individuals, even when the data are controlled for grade and stage. The reasons for this disparity have not been fully uncovered, but there is some recent evidence that Wnt signalling may have a role. Wnt signalling is known to have roles both in cancer progression as well as in organismal ageing...

Research links Black-White health disparities to racial differences in socioeconomic status (SES), but understanding of the role of SES in racial health gaps has been restricted by reliance on static measures of health and socioeconomic well-being that mask the dynamic quality of these processes and ignore the racialized nature of the SES-health connection. Utilizing twenty-three years of longitudinal data from the Panel Study of Income Dynamics (1984-2007), this study uses multilevel growth curve models to examine how multiple dimensions of socioeconomic well-being-including long-term economic history and differential returns to SES-contribute to the life course patterning of Black-White health disparities across two critical markers of well-being: body mass index (N = 9057) and self-rated health (N = 11,329)...

BACKGROUND: In the current antiretroviral (ART) era, the evolution of HIV guidelines and emergence of new ART agents might be expected to impact the times to ART initiation and HIV virologic suppression. We sought to determine if times to AI and virologic suppression decreased and if disparities exist by age, race/ethnicity, and HIV risk. METHODS: We performed a retrospective cohort study of data from 12 sites of the HIV Research Network, a consortium of US clinics caring for HIV-infected patients...

BACKGROUND: American Indian and Alaska Native (AI/AN) breast cancer survivors experience disparities in breast cancer incidence and age-adjusted mortality compared with non-Hispanic white (NHW) breast cancer survivors. In addition, mortality-to-incidence rates indicate that AI/ANs continue to have the poorest survival from breast cancer compared with other racial groups. "Native American Cancer Education for Survivors" (NACES) is a cultural education and support intervention for AI/AN patients with cancer that collects data from voluntary participants through the NACES quality-of-life (QOL) survey regarding their cancer experience and survivor journey...

Conventional correction approaches are unsuitable for effectively correcting remote sensing images acquired in the seriously oblique condition which has severe distortions and resolution disparity. Considering that the extraction of control points (CPs) and the parameter estimation of the correction model play important roles in correction accuracy, this paper introduces an effective correction method for large angle (LA) images. Firstly, a new CP extraction algorithm is proposed based on multi-view simulation (MVS) to ensure the effective matching of CP pairs between the reference image and the LA image...

Over the past decade, scholars and practitioners have called for efforts to reduce disparities in the cost and quality of end-of-life care; a key contributor to these disparities is the underuse of hospice care by African American patients. While previous studies have often relied on interviewing minority individuals who may or may not have been terminally ill, among them only few who were using hospice care services, this essay reports the findings of a grounded theory analysis of interviews with 26 African American hospice patients (n = 10) and lay caregivers (n = 16)...

Black Americans are incarcerated at disproportionate rates, largely due to racial differences in the application of drug laws. Human immunodeficiency virus (HIV) prevalence rates among Black Americans are also disproportionately high. Moreover, availability of and access to HIV prevention services in correctional settings are limited. Recognizing that Blacks are at an elevated risk of contracting HIV, and that incarceration worsens health outcomes, this paper addresses the importance of implementing comprehensive prison-based HIV programs and prevention interventions to improve the health of this vulnerable population...

INTRODUCTION: Cancer is among the leading causes of death in American Indians and Alaska Natives (AI/ANs), with rates increasing over the last two decades. Barriers in accessing cancer screening and treatment likely contribute to this situation. METHODS: We administered structured clinical interviews and conducted descriptive and multiple linear regression analyses of demographic, health, spiritual, and treatment factors associated with self-reported barriers to cancer care among 143 adult AI/AN oncology patients...

A diverse physician workforce is needed to increase access to care for underserved populations, particularly as the Affordable Care Act expands insurance coverage. Yet legal restrictions constrain the extent to which medical schools may use race/ethnicity in admissions decisions. We conducted simulations using academic metrics and socioeconomic data from applicants to a California public medical school from 2011 to 2013. The simulations systematically adjusted medical school applicants' academic metrics for socioeconomic disadvantage...

: American Indians and Alaska Natives (AI/AN) experience significant health disparities relative to the general U.S. POPULATION: In particular, oral diseases affect the majority of the AI/AN population and their prevalence is significantly greater than observed in other demographic sectors of the U.S. POPULATION: The reasons for these disparities are multiple but lack of access to dental care is clearly a contributing factor. The dentist-to-population ratio in many AI/AN communities is less than half the U...

BACKGROUND: This clinical practice guideline addresses six questions related to liberation from mechanical ventilation in critically ill adults. It is the result of a collaborative effort between the American Thoracic Society (ATS) and American College of Chest Physicians (CHEST). METHODS: A multi-disciplinary panel posed six clinical questions in a Population, Intervention, Comparator and Outcomes (PICO) format. A comprehensive literature search and evidence synthesis was performed for each question, which included appraising the certainty in the evidence (i...

Although studies often find racial disparities in policing outcomes, less is known about how suspect race biases police interactions as they unfold. This study examines what is differentially occurring during police-suspect interactions for White, Black, and Latino suspects across time. It is hypothesized that racial bias may be more evident earlier in interactions, when less information about the situation is available. One hundred thirty-nine (62 White, 42 Black, and 35 Latino) use-of-force case files and associated written narratives from a medium to large size urban police department in the United States were analyzed...

In the microevolutionary scales of Entamoeba isolates, the gene migration shows how Entamoeba spp. has epidemiologically drifted among border countries. Five hundred fecal samples were taken from patients suffering gastrointestinal disorders, abdominal pain, and diarrhea at Saggez, northwest Iran located within the border Iraq country. Following parasitological techniques, DNA samples were extracted and amplified by polymerase chain reaction (PCR) of 18S rRNA region to identify Entamoeba infections. To distinguish the Entamoeba spp...

There exists controversy as to the impact gentrification of cities has on the well-being of minorities. Some accuse gentrification of causing health disparities for disadvantaged minority populations residing in neighborhoods that are changing as a result of these socioeconomic shifts. Past scholarship has suggested that fears of displacement and social isolation associated with gentrification lead to poorer minority health. However, there is a lack of research that directly links gentrification to minority health outcomes...

Psychoactive plants contain chemicals that presumably evolved as allelochemicals but target certain neuronal receptors when consumed by humans, altering perception, emotion and cognition. These plants have been used since ancient times as medicines and in the context of religious rituals for their various psychoactive effects (e.g., as hallucinogens, stimulants, sedatives). The ubiquity of psychoactive plants in various cultures motivates investigation of the commonalities among these plants, in which a phylogenetic framework may be insightful...

BACKGROUND: E. histolytica is among the common causes of acute gastroenteritis. The pathogenic species E. histolytica and the nonpathogenic species E. dispar cannot be morphologically differentiated, although correct identification of these protozoans is important for treatment and public health. In many laboratories, the screening of leukocytes, erythrocytes, amoebic cysts, trophozoites and parasite eggs is performed using Native-Lugol's iodine for pre-diagnosis. AIMS: In this study, we aimed to investigate the frequency of E...

The discrete chemical master equation (dCME) provides a fundamental framework for studying stochasticity in mesoscopic networks. Because of the multi-scale nature of many networks where reaction rates have large disparity, directly solving dCMEs is intractable due to the exploding size of the state space. It is important to truncate the state space effectively with quantified errors, so accurate solutions can be computed. It is also important to know if all major probabilistic peaks have been computed. Here we introduce the Accurate CME (ACME) algorithm for obtaining direct solutions to dCMEs...
