A Christian Faith-Based Facebook Intervention for Smoking Cessation in Rural Communities (FAITH-CORE): Protocol for a Community Participatory Development Study

BACKGROUND

Tobacco smoking remains the leading cause of preventable morbidity and mortality in the United States, with significant rural-urban disparities. Adults who live in rural areas of the United States have among the highest tobacco smoking rates in the nation and experience a higher prevalence of smoking-related deaths and deaths due to chronic diseases for which smoking is a causal risk factor. Barriers to accessing tobacco use cessation treatments are a major contributing factor to these disparities. Adults living in rural areas experience difficulty accessing tobacco cessation services due to geographical challenges, lack of insurance coverage, and lack of health care providers who treat tobacco use disorders. The use of digital technology could be a practical answer to these barriers.

OBJECTIVE

This report describes a protocol for a study whose main objectives are to develop and beta test an innovative intervention that uses a private, moderated Facebook group platform to deliver peer support and faith-based cessation messaging to enhance the reach and uptake of existing evidence-based smoking cessation treatment (EBCT) resources (eg, state quitline coaching programs) for rural adults who smoke.

METHODS

We will use the Integrated Theory of Health Behavior Change, surface or deep structure frameworks to guide intervention development, and the community-based participatory research (CBPR) approach to identify and engage with community stakeholders. The initial content library of moderator postings (videos and text or image postings) will be developed using existing EBCT material from the Centers for Disease Control and Prevention Tips from Former Smokers Campaign. The content library will feature topics related to quitting smoking, such as coping with cravings and withdrawal and using EBCTs with faith-based message integration (eg, Bible quotes). A community advisory board and a community engagement studio will provide feedback to refine the content library. We will also conduct a beta test of the intervention with 15 rural adults who smoke to assess the recruitment feasibility and preliminary intervention uptake such as engagement, ease of use, usefulness, and satisfaction to further refine the intervention based on participant feedback.

RESULTS

The result of this study will create an intervention prototype that will be used for a future randomized controlled trial.

CONCLUSIONS

Our CBPR project will create a prototype of a Facebook-delivered faith-based messaging and peer support intervention that may assist rural adults who smoke to use EBCT. This study is crucial in establishing a self-sufficient smoking cessation program for the rural community. The project is unique in using a moderated social media platform providing peer support and culturally relevant faith-based content to encourage adult people who smoke to seek treatment and quit smoking.

Human uric acid transporter 1 (hURAT1): an inhibitor structure-activity relationship (SAR) study

The current study describes the chemical synthesis of a series of (2-ethylbenzofuran-3-yl)(substituted-phenyl)methanone compounds and their subsequent in vitro testing via oocytes expressing hURAT1. The experimental data support the notion that a potent hURAT1 inhibitor requires an anion (i.e., a formal negative charge) to interact with the positively charged hURAT1 binding pocket. An anion appears to be a primary requirement in order to be a hURAT1 substrate (i.e., urate) or inhibitor. We discuss the inhibitor structure-activity relationship and how electronically donating or withdrawing groups attached to the B-ring can decrease or increase inhibitory potency, respectively.

Activated CD8+ T cells are involved in elimination of Candida albicans from the livers of mice

We have investigated the course of infection of Balb/c mice with Candida albicans. After intravenous infection of mice, the yeasts were evenly distributed in the liver sections. There was a 90% reduction in the yeasts found within 7 days after infection. This reduction was accompanied by an increase in the number of phagocytic cells (Mac-1+, Gr-1+) in cellular infiltrates around the yeast cells. Furthermore, both CD4+ and CD8+ T lymphocytes were found in these pseudogranulomata, with the CD8+ cells in the periphery. Peak amounts of the cell types investigated were found at days 5 and 6 post infection, with an increased expression of receptors for interleukin 2 (IL-2R) on the surface of CD8+ cells. At day 14 of infection, the same levels as those in control mice were reached. At this time, the yeasts were virtually eliminated from the liver. By using simultaneous detection of cell surface markers and yeast cells in immunohistology, these data demonstrate the close association of fungal cells, phagocytes, TH and TC cells in pseudogranulomata during elimination of Candida albicans from the livers of mice.

Failure of FK 506 to suppress the T cell-mediated immunity of mice to Listeria monocytogenes

Listeria monocytogenes belongs to the group of intracellular bacteria, which means that they reside and multiply within host cells. The protective immunity against such an infection is mediated by cellular immune mechanisms. Whereas the CD8+ T cell population plays a major role therein, the CD4+ T cells are held to be of minor importance in this defence system. Consequently, one can understand that immune suppression with FK 506 which acts primarily on this latter T cell subset, does not interfere with protective immunity of mice infected with L. monocytogenes. We have demonstrated that the drug blocks neither curing of primary infection, nor formation of granulomas, nor induction of cell populations capable of mediating adoptive transfer of immunity, nor expression of pre-existing immunity.

Oleic acid lung injury increases plasma prostaglandin levels

To determine whether lung injury causes increased plasma prostaglandin (PG) levels, 35 rabbits received oleic acid and 35 served as controls. Half of each group also received 4 ml/kg of Intralipid over one hour and at least five in each subgroup received indomethacin 7.5 mg/kg. Arterial and venous plasma concentrations of PGE2, 6-keto-PGF1 alpha, and PGF2 alpha-M were measured. Venous PGE2 was significantly higher in the oleic acid-injured than in the normal lung group, 1560 +/- 270 (Mean +/- SEM) versus 880 +/- 140 pg/ml (p less than .05). Plasma levels were reduced by 50% with indomethacin, but PGE2 levels remained significantly higher than in the normal lung group, 850 +/- 180 versus 480 +/- 60 for arterial (p less than .05) and 820 +/- 140 versus 480 +/- 80 for venous (p less than .05), respectively. PGF2 alpha-M levels were significantly higher in the lung injury group, 240 +/- 50 versus 50 +/- 40 pg/ml for arterial (p less than .05) and 220 +/- 50 versus 95 +/- 40 for venous (p less than .05), respectively. These lung injury-related increases in PGE2 and PGF2 alpha-M appear related both to increased pulmonary production and to decreased pulmonary clearance. With Intralipid infusion, however, arterial PGE2 increased by 500 +/- 260 pg/ml compared to baseline (p less than .05) with no change in venous PGE2, indicating in this instance that the increase in arterial PGE2 levels is related to increased pulmonary production.

Junctions between lens cells in differentiating cultures: structure, formation, intercellular permeability, and junctional protein expression

We previously described cultures of chick embryo lens cells which displayed a marked degree of differentiation. In this report, the junctions found between the lens fiber-like cells in the differentiated "lentoids" are characterized in several ways. Thin-section methods with electron microscopy first demonstrated that numerous, large junctions between lentoid cells accompanied the other differentiated features of these cells. Freeze-fracture techniques, including quantitative analysis, then revealed that (a) junctional particles were loosely arranged as is typical of fiber cells, (b) the population of individual junctional areas in culture was indistinguishable from that found in 10- to 12-day chick embryo lenses, and (c) apparent junction formation occurred during the development of the lens cells, with lacy arrays of particles being associated with fiber-like junctions. In addition, gap junctions with hexagonally packed particles, typical of lens epithelial cells, largely disappeared during the course of differentiation. Injection of tracer dyes into lentoid cells resulted in rapid intercellular movement of dye, consistent with functional cell-to-cell channels connecting lentoid cells. During the development of the lens cells in culture, as junction formation occurred, an increase of approximately eight-fold in MP28 protein was observed within the cells. These combined results indicate that (a) extensive lens fiber junctions and functional cell-to-cell channels are found between differentiated lentoid lentoid cells in vitro, (b) lens fiber junctions appear to form during the course of lens cell differentiation in culture, (c) a significant increase occurs in the putative junctional protein before the cultures are highly developed, (d) the increased levels of MP28 and junction formation may be required for the full expression of the differentiated state in the lens fiber cell, and (e) this culture system should prove to be valuable for additional experiments on lens junctions and for other studies requiring the development of lens fiber cells in vitro.
