REVIEW
David A Baltrus
Growth patterns of individual plants and evolutionary trajectories of plant communities are intimately linked with and are critically affected by host-associated microbiomes. Research across systems has begun to shed light on how these phytobiomes are established under laboratory and natural conditions, and have cultivated hope that a better understanding of the governing principles for host-microbe interactions can guide attempts to engineer microbiomes to boost agricultural yields. One important, yet relatively understudied, parameter in regards to phytobiome membership is the degree to which specialization and coevolution between plant species and microbes provides structure to these communities...

BACKGROUND: Squamous cell carcinoma (SCC) is considered the most frequent skin cancer in black people. Its incidence is not known in the Afro-Caribbean population. OBJECTIVE: To assess the incidence of SCC in Guadeloupe, the largest island of the Lesser Antilles (405 000 inhabitants, mostly black people of African and European descent). The second objective was to characterize clinical and histological patterns of SCC occurring in the Afro-Caribbean community. METHODS: This retrospective study was conducted over an 11-year period (2000-2010)...

Most homes in the Navajo Nation use wood as their primary heating fuel, often in combination with locally-mined coal. Previous studies observed health effects linked to this solid-fuel use in several Navajo communities. Emission factors (EF) for common fuels used by the Navajo have not been reported using a relevant stove type. In this study, two softwoods (Ponderosa Pine and Utah Juniper) and two high-volatile bituminous coals (Black Mesa and Fruitland) were tested with an in-use residential conventional wood stove (homestove) using a modified ASTM/EPA protocol...

Reports of sponge disease are becoming increasingly frequent, although almost all instances involve shallow-water, tropical species. Here, we describe the first disease affecting the deep-water sponge, Geodia barretti. The disease is characterised by brown/black discolouration of the sponge tissue, extensive levels of tissue disintegration and increased levels of fouling. Disease prevalence was quantified using video survey transects conducted between 100 and 220 meters in Korsfjorden, Norway and the microbial communities of healthy and diseased sponges were compared using 16S rRNA gene sequencing...

We aimed to determine in a randomized trial if young adult black, Hispanic, and white men-who-have-sex-with-men (YMSM) are more likely to complete home-based oral fluid rapid HIV self-testing than either mail-in blood sample collection or medical facility/community organization-based HIV testing. Stratified by race/ethnicity, participants were randomly assigned to use a free oral fluid rapid HIV self-test (n = 142), a free mail-in blood sample collection HIV test (n = 142), or be tested at a medical facility/community organization of their choice (n = 141)...

After HIV diagnosis, heterosexuals in high-poverty urban areas evidence delays in linkage to care and antiretroviral therapy initiation compared to other groups. Yet barriers to/facilitators of HIV care among these high-risk heterosexuals are understudied. Under the theory of triadic influence, putative barriers to HIV care engagement include individual/attitudinal-level (e.g., fear, medical distrust), social-level (e.g., stigma), and structural-level influences (e.g., poor access). Participants were African-American/Black and Hispanic adults found newly diagnosed with HIV (N = 25) as part of a community-based HIV testing study with heterosexuals in a high-poverty, high-HIV-incidence urban area...

The House and Ball community is an important cultural manifestation of resiliency for Black and Latino gay and bisexual men and transgender women. Participants at the August, 2013 House of Latex Ball in New York City were surveyed about insurance coverage, health care access, experiences in health care, and housing instability. The sample (n = 367) was 58% Black/African American and 20% Hispanic/Latino, with a mean age of 31. Fifty-five percent were gay and bisexual men. While only 6% identified as transgender, nearly half were gender nonconforming...

Evidence suggests that men with recent histories of incarceration are more likely to engage in high-risk sexual activity, however there is limited research exploring how having been recently released from prison might impact men's sexual risk behaviours or sexual partnering. This qualitative study explores the ways in which exposure to incarceration impacts the dynamics of sexual partnering among recently released Black men in Baltimore, USA. In-depth interviews were conducted with 19 recently released Black men between 21-45 years of age living in the city...

Advertising via Facebook to elicit involvement in clinical trials has demonstrated promise in expanding geographic reach while maintaining confidentiality. The purpose of this study is to evaluate Facebook advertising to reach at-risk, predominately African American or Black women in higher HIV prevalence communities for an HIV prevention clinical trial, and to compare baseline characteristics to those recruited on-the-ground. Maintaining confidentiality and the practical aspects of creating and posting ads on Facebook are described...

Alzheimer's disease (AD) is the most common type of dementia among individuals 65 or older. There are more than 5 million diagnosed cases in the US alone and this number is expected to triple by 2050. Therefore, AD has reached epidemic proportions with significant socioeconomic implications. While aging in general is the greatest risk factor for AD, several additional demographic factors that have contributed to the rise in AD in the US are under study. One such factor is associated with the relatively fast growth of the Latino population...

OBJECTIVES: Deficiency of 25-hydroxyvitamin D (25[OH]D) is associated with increased risk for cardiovascular disease, perhaps mediated through dyslipidemia. Deficient 25(OH)D is cross-sectionally associated with dyslipidemia, but little is known about longitudinal lipid changes. The aim of this study was to determine the relationship of 25(OH)D deficiency to longitudinal lipid changes and risk for incident dyslipidemia. METHODS: This was a longitudinal community-based study of 13 039 participants from the ARIC (Atherosclerosis Risk in Communities) study who had 25(OH)D and lipids measured at baseline (1990-1992) and lipids remeasured in 1993 to 1994 and 1996 to 1998...

BACKGROUND: The physical and psychological impact of female genital mutilation / cutting (FGM/C) can be substantial, long term, and irreversible. Parts of the health sector in Australia have developed guidelines in the management of FGM/C, but large gaps exist in community and professional knowledge of the consequences and treatment of FGM/C. The prevalence of FGM/C amongst Australian women is unknown. Our article reviews the literature on research on FGM/C in Australia, which focuses on health system response to women and girls with FGM/C...

Realist reviews are a new form of knowledge synthesis aimed at providing middle-range theories (MRTs) that specify how interventions work, for which populations, and under what circumstances. This approach opens the 'black box' of an intervention by showing how it triggers mechanisms in specific contexts to produce outcomes. We conducted a realist review of health user fee exemption policies (UFEPs) in sub-Saharan Africa (SSA). This article presents how we developed both the intervention theory (IT) of UFEPs and a MRT of free public healthcare seeking in SSA, building on Sen's capability approach...

The boundary zone between two different hydrological regimes is often a biologically enriched environment with distinct planktonic communities. In the center of the Amazon River basin, muddy white water of the Amazon River meets with black water of the Negro River, creating a conspicuous visible boundary spanning over 10 km along the Amazon River. Here, we tested the hypothesis that the confluence boundary between the white and black water rivers concentrates prey and is used as a feeding habitat for consumers by investigating the density, biomass and distribution of mesozooplankton and ichthyoplankton communities across the two rivers during the rainy season...

Background.: The Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) equations are recommended for glomerular filtration rate (GFR) estimation in the general population. They have not been evaluated in community-based populations, including Blacks at higher levels of GFR, but are commonly applied in such populations. Methods.: In an ancillary study of Multi-Ethnic Study of Atherosclerosis conducted at one site, we evaluated the performance of the CKD-EPI equations for creatinine (eGFRcr), cystatin C (eGFRcys) or the combination (eGFRcr-cys) compared with GFR measured as plasma clearance of iohexol...

Importance: Colorectal cancer (CRC) screening is underused, especially among vulnerable populations. Decision aids and patient navigation are potentially complementary interventions for improving CRC screening rates, but their combined effect on screening completion is unknown. Objective: To determine the combined effect of a CRC screening decision aid and patient navigation compared with usual care on CRC screening completion. Design, Setting, and Participants: In this randomized clinical trial, data were collected from January 2014 to March 2016 at 2 community health center practices, 1 in North Carolina and 1 in New Mexico, serving vulnerable populations...

The contribution of small mammal ecology to the understanding of macroecological patterns of biodiversity, population dynamics and community assembly has been hindered by the absence of large datasets of small mammal communities from tropical regions. Here we compile the largest dataset of inventories of small mammal communities for the Neotropical region. The dataset reviews small mammal communities from the Atlantic forest of South America, one of the regions with the highest diversity of small mammals and a global biodiversity hotspot, though currently covering less than 12% of its original area due to anthropogenic pressures...

A 58-year-old man with hepatitis B cirrhosis noticed black stools and underwent an endoscopy at a community hospital. The presence of esophageal varices (EVs) was confirmed, but the bleeding point was not found. He was referred to our institution and underwent a second endoscopy. Extensive white patches of esophageal candidiasis were visible on endoscopy by white-light imaging (WLI), but it was difficult to find the fibrin cap of the EVs. This was easier under narrow-band imaging (NBI), however, as the color turned red from absorption by hemoglobin adhered to it...

While cardiovascular screening protocols exist, they have been focused on teenaged and college aged athletes versus adult athletes. To assess community awareness of health screening as related to adult athletes, we have created an internet questionnaire (QN). The survey was posted through social media (e.g. Facebook, Reddit, Flotrack and Active), for 11 months, that queried sports history, medical history, and symptoms while playing sports. A total of 3,750 respondents (R) answered the questionnaire, 2,776 male and 974 female...
