Background: The high prevalence of uncontrolled hypertension (systolic blood pressure [SBP] ≥140 mmHg or diastolic blood pressure [DBP] ≥90 mmHg) in Black patients represents a significant racial health disparity in the United States.

Aims: This study evaluated the efficacy of a telephone-based strategy for inviting high-risk patients with severe hypertension to weekly self-management education classes. Further, the study assessed how the outreach intervention correlated with relevant quality improvement outcomes, including improved blood pressure and primary care follow-up among our clinic population of Black men with severe hypertension.

Background: Uncontrolled hypertension disproportionately affects Black men. Patient engagement with health promotion and health behavior programs for hypertension control is low. We held evidence-based hypertension classes at a Federally Qualified Health Center.

Structural racism has contributed to persistent racial disparities in hypertension control, with Black men suffering the highest prevalence of uncontrolled hypertension. Lincoln Community Health Center, our urban Federally Qualified Health Center (FQHC), aimed to use hypertension self-management classes to improve hypertension control among our clinic patients, particularly Black men. Patients attending classes learned about hypertension, were given blood pressure cuffs to use at home, and had the opportunity to speak to physicians in a group setting.

Background: The North Carolina Breast and Cervical Cancer Control Program (NC BCCCP) provides breast cancer screening services to underserved women to mitigate disparities in access to care. The authors sought to characterize this understudied population.

Methods: Women 21 years old or older who underwent their first breast cancer screen through NC BCCCP from 2008 to 2018 were included.

Photoperiod is an important external stimulus governing the precise timing of the floral transition in plants. Members of the FLOWERING LOCUS T (FT)-like clade of phosphatidylethanolamine-binding proteins induce this developmental process in numerous species by forming regulatory protein complexes with FD-like bZIP transcription factors. We identified several thus far unknown FT-like and FD-like genes in the genus Nicotiana and found that, even in the day-neutral species Nicotiana tabacum, floral initiation requires the photoperiod-dependent expression of several FT-like genes.

Background And Objectives: A lateral flow assay for simultaneous blood group typing of ABO, RhD, C, E, c, e, Cw and K with stable end-point and without centrifugation is in routine use since several years (MDmulticard ). The typing of extended phenotype parameters belonging to the Duffy, Kidd, MNSs blood group systems and others, however, has not yet been demonstrated for this technique. Reliable detection of Fy , a weak Fy phenotype with a pronounced quantitative reduction of the number of Fy antigens on the erythrocyte surface, remains a weakness of current serological blood grouping techniques.

Stimulation of plant productivity caused by Agaricus fairy rings has been reported, but little is known about the effects of these fungi on soil aggregation and the microbial community structure, particularly the communities that can bind soil particles. We studied three concentric zones of Agaricus lilaceps fairy rings in Eastern Montana that stimulate western wheatgrass (Pascopyrum smithii): outside the ring (OUT), inside the ring (IN), and stimulated zone adjacent to the fungal fruiting bodies (SZ) to determine (1) soil aggregate proportion and stability, (2) the microbial community composition and the N-acetyl-β-D-glucosaminidase activity associated with bulk soil at 0-15 cm depth, (3) the predominant culturable bacterial communities that can bind to soil adhering to wheatgrass roots, and (4) the stimulation of wheatgrass production. In bulk soil, macroaggregates (4.

Aims: To simplify the determination of the nuclear condition of the pathogenic Rhizoctonia, which currently needs to be performed either using two fluorescent dyes, thus more costly and time-consuming, or using only one fluorescent dye, thus less accurate.

Methods And Results: A red primary fluorescence (autofluorescence) of the hyphal cell walls and septa of Rhizoctonia spp. with green excitation is evidenced in Rhizoctonia spp.

The exotic rangeland perennial Lepidium draba occurs as a noxious weed in 22 states, mostly in the western United States. Because chemical control measures against this invasive perennial, a member of the Brassicaceae, have not achieved adequate results, biological control is being pursued. While inventories of arthropods that feed on L.

Exotic perennial Lepidium draba, native to Eurasia, is an invasive weed in dense stands in rangelands and disturbed areas in several states of the western United States and an agricultural weed in the prairie provinces of Canada. To determine strategies, such as a potential multipathogen strategy (1), for biological control of the weed, surveys that included the native range were conducted in spring 2009 to detect diseases that occur on this weed. Several stunted and chlorotic plants were found scattered throughout a stand of L.

Spotted knapweed (SKW), Centaurea stoebe L., is a nonindigenous species that is invasive over large areas in the United States, especially in the west. It has been estimated that infestations of SKW cause $42 million in direct and indirect economic losses annually (2), and the weed could potentially invade 13.

Hypertrophy and hyperplasia resembling crown galls were found on roots of Euphorbia esula/virgata at a single site in east-central Hungary in 2005. E. esula/virgata, known as leafy spurge in North America, is an invasive species causing substantial economic losses to the value of grazing lands in the Northern Great Plains of the United States and is the target of biological control.

Safflower is an oilseed crop adapted to the small-grain production areas of the western Great Plains, including the Northern Plains Area (NPA). In the NPA, safflower production is being evaluated for potential rotation with sugar beet. Safflower is susceptible to Cercospora carthami, whereas sugar beet is susceptible to C.

Objective: We examined the relationship between early and exclusive continuity of care at the initial source of care and immunization coverage.

Methods: We used a cohort study design with 641 randomly selected children initiating care before 3 months and making 2 or more visits to an inner-city practice network. We used 2 complementary data sources: medical records and the New York City Department of Health Citywide Immunization Registry.

Background: In 2002, the Advisory Committee on Immunization Practices (ACIP) recommended vaccine doses administered < or = 4 days before the minimum age or interval be counted as valid. The study objective was to assess the impact of the 4-day grace period on the need for revaccination and associated costs in a low-income community, compared to standard practice (i.e.

In 1996 we launched a community-provider partnership to raise immunization coverage for children aged younger than 3 years in Northern Manhattan, New York City. The partnership was aimed at fostering provider knowledge and accountability, practice improvements, and community outreach. By 1999 the partnership included 26 practices and 20 community groups.

Objectives: To determine the prevalence of merosin deficiency in cases of unclassified congenital muscular dystrophy and to determine the temporal stability of merosin epitopes in fixed and stored archival material.

Materials And Methods: Using an antibody to human merosin we retrospectively studied 12 cases of undiagnosed muscular dystrophy from our files to determine the prevalence of merosin deficiency. Where fresh muscle was not available, unstained stored cryostat sections or destained archival stored sections were incubated with the merosin antibody.

This study was designed to increase smoking cessation rates, quit attempts, and cutting down among low-income African Americans using brief clinician advice in conjunction with socioculturally appropriate self-help smoking cessation/relapse prevention materials. Physicians and nurses were instructed in the National Cancer Institute's smoking intervention at inservice sessions. Smokers interviewed in a Harlem, New York clinic waiting room were recontacted 7 months later by telephone or mail (77% response).
