Compared with all other racial and ethnic groups in the U.S., African Americans are disproportionally affected by lung cancer, both in terms of incidence and survival. It is likely that smoking, as the main etiological factor associated with lung cancer, contributes to these disparities, but the precise mechanism is still unclear. This paper seeks to explore the history of lung cancer disparities and review to the literature regarding the various factors that contribute to them.

The present work reports on a graphene-like material that is promising for photodetection applications due to its high optical absorption and layer-dependent properties. To date, only narrowband photodetectors have been realized; therefore, extending the working wavelength is becoming more imperative for applications such as high-contrast imaging and remote sensing. In this work, we developed a novel detection technique that provides enhanced performance across the infrared and terahertz bands by using an antenna-assisted top-gated black phosphorus phototransistor...

Allergic asthma is a chronic pulmonary inflammatory disease initiated by exposure to normally harmless allergens and marked by bronchial hyperreactivity. It affects more than 300 million people worldwide. Asthma often starts in childhood. Epidemiological studies show that there are sexual disparities in the prevalence and severity of asthma. Before the age of 10, the disease is more common in boys. This tendency reverses at puberty suggesting a regulating role of the sex hormones. In this synthesis, we summarize current knowledge on the role of sex hormones in allergic inflammation, with a particular focus on the impact of androgens on the development and function of recently introduced group 2 innate lymphoid cell subsets (ILC2) as critical actors in the initiation of allergic responses...

Tracheotomy is widely used in intensive care units, albeit with great disparities between medical teams in terms of frequency and modality. Indications and techniques are, however, associated with variable levels of evidence based on inhomogeneous or even contradictory literature. Our aim was to conduct a systematic analysis of the published data in order to provide guidelines. We present herein recommendations for the use of tracheotomy in adult critically ill patients developed using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) method...

OBJECTIVES: Although individual socioeconomic status has been linked with risk of traumatic injury, there has been relatively little research into the question of how economic changes may impact trauma admission rates in neighborhoods with different socioeconomic backgrounds. METHODS: This study pairs ZIP code-level data on trauma admissions with county-level data on unemployment to assess differences in the type of changes experienced in more and less affluent neighborhoods of the Detroit metropolitan area between 2006 and 2014...

Introduction: American Indians/Alaska Natives have the highest commercial tobacco use in the United States, resulting in higher tobacco-caused deaths and diseases than the general population. Some American Indians/Alaska Natives use commercial tobacco for ceremonial as well as recreational uses. Because federally-recognized Tribal lands are sovereign, they are not subject to state cigarette taxes and smokefree laws. This study analyzes tobacco industry promotional efforts specifically targeting American Indians/Alaska Natives and exploiting Tribal lands to understand appropriate policy responses in light of American Indians'/Alaska Natives' unique sovereign status and culture...

Background: LGBT populations use tobacco at disparately higher rates nationwide, compared to national averages. The tobacco industry has a history targeting LGBT with marketing efforts, likely contributing to this disparity. This study explores whether exposure to tobacco content on traditional and social media is associated with tobacco use among LGBT and non-LGBT. Methods: This study reports results from LGBT (N=1,092) and non-LGBT (N=16,430) respondents to a 2013 nationally representative cross-sectional online survey of US adults (N=17,522)...

Aims: Alcohol problems are most prevalent in young adulthood and decrease thereafter, but some studies find that racial/ethnic minorities have elevated alcohol risk beyond the 20s. This study examines racial/ethnic differences in the transitions into and out of alcohol problems, and whether these are explained by heavy drinking (HD), socioeconomic disadvantages and adult role transitions from the 20s to 30s. Short summary: Racial/ethnic groups had similar risks for earlier onset and recurrence/persistence of alcohol problems, but Blacks were at significantly greater risk than Whites for later onset in the 30s...

Using a national longitudinal survey data set from the Higher Education Research Institute, this study tested whether students who identified as a sexual minority (for example, lesbian, gay, bisexual, or queer) were more or less likely to persist after 4 years in science, technology, engineering, and mathematics (STEM) fields, as opposed to switching to a non-STEM program, compared to their heterosexual peers. A multilevel regression model controlling for various experiences and characteristics previously determined to predict retention in STEM demonstrated that, net of these variables, sexual minority students were 8% less likely to be retained in STEM compared to switching into a non-STEM program...

Minority stress theory has widespread research support in explaining health disparities experienced by sexual and gender minorities. However, less is known about how minority stress impacts multiply marginalized groups, such as lesbian, gay, bisexual, and transgender people of color (LGBT POC). Also, although research has documented resilience in the face of minority stress at the individual level, research is needed that examines macro-level processes such as community resilience (Meyer, 2015). In the current study, we integrate minority stress theory and intersectionality theory to examine multiple minority stress (i...

Reducing antimicrobial use (AMU) in livestock is requested by Public Health authorities. Ideally, this should be achieved without jeopardizing production output or animal health and welfare. Thus, efficient measures must be identified and developed to target drivers of AMU. Veterinarians play a central role in the identification and implementation of such efficient interventions. Sixty-seven veterinarians with expertise in livestock production in Denmark, Portugal, and Switzerland participated in an expert opinion study aimed at investigating experiences and opinions of veterinarians about the driving forces and practices related to AMU in the main livestock sectors (broiler, dairy cattle, fattening/veal calf, and pig industry) of the aforementioned countries...

Breast cancer, a heterogeneous disease with variable pathophysiology and biology, is classified into four major subtypes. While hormonal- and antibody-targeted therapies are effective in the patients with luminal and HER-2 subtypes, the patients with triple-negative breast cancer (TNBC) subtype do not benefit from these therapies. The incidence rates of TNBC subtype are higher in African-American women, and the evidence indicates that these women have worse prognosis compared to women of European descent. The reasons for this disparity remain unclear but are often attributed to TNBC biology...

Drug-induced liver injury (DILI) remains a clinical challenge due to the poorly predictable outcomes. Accordingly, considerable efforts have been devoted to unravel the risk factors responsible for DILI worsening toward acute liver failure (ALF), liver transplantation (LT), and/or death. From a pathogenic point of view, exhaustion of drug metabolizing pathways, cell death mechanisms, activation of local immune cells, such as Kupffer cells, and recruitment of inflammatory leukocytes including monocytes and lymphocytes are key drivers of DILI progression...

From a psychological perspective, the menstrual cycle has been a research topic for more than 50 years. The most recent menstrual cycle research has been driven by an increased interest in sex differences in neuroscience, and the urge to understand sex disparities in prevalence, clinical presentation, and treatment response in psychiatric or neurologic disorders. Indeed, the menstrual cycle is an excellent model of ovarian steroid influence on emotion, behavior, and cognition. This review summarizes the emotion-related and cognitive findings of methodologically sound menstrual cycle studies...

BACKGROUND: Few studies have specifically focused on demographic and socio-economic characteristics associated with snacking in adults, whereas their identification could be useful for defining effective public health measures. The aim of our study was to assess the associations of these factors with daily snacking behavior and its dietary quality. METHODS: This cross-sectional study included 84,692 women and 23,491 men from the NutriNet-Santé cohort study. Occurrence of snacking, energy intake from snacks, snack nutrient, and energy densities were assessed using 24-h dietary records of weekdays at baseline...

We study a thermal gradient induced current Ith flow in potassium-doped two-dimensional anisotropic black phosphorus (BP) with semi-Dirac dispersion. The prototype device is a BP channel clamped between two contacts maintained at unequal temperatures. The choice of BP lies in the predicted efficient thermoelectric behaviour. A temperature-induced difference in the Fermi levels of the two contacts drives the current (typified by the electro-thermal conductance) which we calculate using the Landauer transport equation...
