Barriers and facilitators to implementing a multilevel, multicomponent intervention promoting colorectal cancer screening in health centers: a qualitative study of key informant perspectives.

Background: Colorectal cancer (CRC) continues to be a major cause of death in the U.S. despite the availability of effective screening tools.

Rationale and design of a pilot randomized controlled trial to increase moderate-to-vigorous physical activity in preadolescent Latina girls and their mothers.

Background: Hispanic/Latina girls have a low prevalence of moderate-intensity physical activity (PA) compared to their male counterparts and non-Hispanic White girls. Mothers influence their children's activity levels by creating and supporting PA opportunities, modeling PA, and reinforcing children's efforts to be physically active. The trial will evaluate a mother-daughter intervention to promote PA and examine potential mechanisms of change including mothers' PA, parenting regarding PA, and mother-daughter communication.

Exploring Culturally Based Treatment Options for Opioid Use Disorders Among American Indian and Alaska Native Adults in California.

Objective: American Indian and Alaska Native (AIAN) communities have been severely affected by the opioid epidemic, resulting in high opioid overdose death rates and disrupted community life. An added complexity is the diversity of AIAN communities throughout California, with regional differences, resources, infrastructure, and economic opportunities. This study examined the perspective of 163 AIANs in California to assess culturally based or traditional healing treatment modalities to treat opioid/substance use disorder.

Substance use disorder and homelessness among American Indians and Alaska Natives in California.

American Indian and Alaska Native (AIAN) communities have higher rates of substance use than other racial and ethnic groups. Substance use disorder (SUD) is tied to the increased risk of experiencing homelessness. National policies have also led to the disproportionate rates of homelessness among AIAN communities.

An opioid and substance use disorder needs assessment study for American Indian and Alaska Native youth in California.

American Indian and Alaska Native (AIAN) youth demonstrate significant substance use and mental health disparities and represent a highly underserved population with regard to effective services. A community-based needs assessment study of urban and rural AIAN youth throughout California was conducted to inform the development of community-based, culturally relevant opioid and substance use services. This study examined AIAN youth experiences with opioid and other substance use disorders (OUD/SUD) in their communities, utilization of existing programs, and service system recommendations.

Phenome-Wide Scan Finds Potential Orofacial Risk Markers for Cancer.

Cancer is a disease caused by a process that drives the transformation of normal cells into malignant cells. The late diagnosis of cancer has a negative impact on the health care system due to high treatment cost and decreased chances of favorable prognosis. Here, we aimed to identify orofacial conditions that can serve as potential risk markers for cancers by performing a phenome-wide scan (PheWAS).

An Argument Against Extraction as a Treatment Alternative for Restorable Teeth.

Extraction is commonly presented as a treatment alternative for restorable teeth, and patients are biased to choose it for a variety of reasons. However, without subsequent rehabilitation, patients' health, function, and esthetics could be compromised. This article explores problematic outcomes where extraction was offered as a treatment option when teeth were restorable; a case report example demonstrates this issue.

Statewide collaborative partnerships among American Indian and Alaska Native (AI/AN) communities in California to target the opioid epidemic: Preliminary results of the Tribal Medication Assisted Treatment (MAT) key informant needs assessment.

American Indian and Alaska Native (AI/AN) communities have disproportionately been impacted by the opioid epidemic with the second highest opioid-related overdose death rates compared to other ethnic groups. The diversity among California AI/AN tribes, including regional differences in economic opportunities, tribal affiliation and organization, resources and infrastructure, requires a strong community-based partnership approach to assess global statewide patterns in service availability, acceptability, and utilization, as well as capturing the unique challenges and service needs within each region. This article describes a statewide community-based needs assessment of strengths and weakness among key informants in CA to identify facilitators and barriers to treatment of substance use disorders (SUD) and opioid use disorders (OUD).

Surface morphologic evaluation of orthodontic bonding systems under conditions of cariogenic challenge.

Orthodontic bonding systems are submitted to demineralization and remineralization dynamics that might compromise their surface smoothness, and favor biofilm aggregation and caries development. The aim of the present study was to evaluate the effects of a cariogenic challenge model (in vitro pH-cycling model) on the surface roughness and topography of 3 bonding materials: Transbond™ XT (XT), Transbond™ Plus Color Change (PLUS) and Fuji Ortho™ LC (FUJI), by means of Atomic Force Microscopy (AFM). Six specimens with standardized dimensions and surface smoothness were fabricated per group, and the materials were manipulated in accordance with the manufacturers' instructions.

Angle Class III malocclusion treated with mandibular first molar extractions.

A Class III malocclusion associated with dental asymmetry is a complex diagnostic and treatment problem in orthodontics. The goals of maintaining or improving the facial profile and achieving good function are decisive factors when considering whether to plan a surgical or a nonsurgical treatment approach. A fixed appliance in combination with extractions could be considered for nonsurgical management of this type of malocclusion in the permanent dentition.

Analyzing Brazilian vehicle documents for authenticity by easy ambient sonic-spray ionization mass spectrometry.

Using desorption/ionization techniques such as easy ambient sonic-spray ionization mass spectrometry (EASI-MS), it is possible to analyze documents of Brazilian vehicles for authenticity, providing a chemical profile directly from the surface of each document. A method for the detection of counterfeit documents is described, and the falsification procedure is elucidated. Forty authentic and counterfeit documents were analyzed by both positive and negative ion modes, EASI(±)-MS.

HIV-1 disease-influencing effects associated with ZNRD1, HCP5 and HLA-C alleles are attributable mainly to either HLA-A10 or HLA-B*57 alleles.

A recent genome-wide association study (GWAS) suggested that polymorphisms in or around the genes HCP5, HLA-C and ZNRD1 confer restriction against HIV-1 viral replication or disease progression. Here, we also find that these alleles are associated with different aspects of HIV disease, albeit mainly in European Americans. Additionally, we offer that because the GWAS cohort was a subset of HIV-positive individuals, selected based in part on having a low viral load, the observed associations for viral load are magnified compared with those we detect in a large well-characterized prospective natural history cohort of HIV-1-infected persons.

Independent effects of genetic variations in mannose-binding lectin influence the course of HIV disease: the advantage of heterozygosity for coding mutations.

Background: The in vivo impact of mannose-binding lectin (MBL), a molecule involved in innate immunity, on the pathogenesis of human immunodeficiency virus (HIV)-1 infection and AIDS is unknown.

Methods: A total of 1102 HIV-positive and 2213 HIV-negative adult subjects were screened for polymorphisms in the coding and promoter regions of MBL2, the gene that encodes MBL.

Results: Variations in MBL2 did not influence the risk of acquiring HIV-1.

HIV-1 infection and AIDS dementia are influenced by a mutant MCP-1 allele linked to increased monocyte infiltration of tissues and MCP-1 levels.

Studies in humans and in experimental models of HIV-1 infection indicate an important role for monocyte chemoattractant protein-1 (MCP-1; also known as CC chemokine ligand 2), a potent chemoattractant and activator of mononuclear phagocytes (MP) in the pathogenesis of HIV-associated dementia (HAD). We determined the influence of genetic variation in MCP-1 on HIV-1 pathogenesis in large cohorts of HIV-1-infected adults and children. In adults, homozygosity for the MCP-1 -2578G allele was associated with a 50% reduction in the risk of acquiring HIV-1.

Extensive repertoire of membrane-bound and soluble dendritic cell-specific ICAM-3-grabbing nonintegrin 1 (DC-SIGN1) and DC-SIGN2 isoforms. Inter-individual variation in expression of DC-SIGN transcripts.

Expression in dendritic cells (DCs) of DC-SIGN, a type II membrane protein with a C-type lectin ectodomain, is thought to play an important role in establishing the initial contact between DCs and resting T cells. DC-SIGN is also a unique type of human immunodeficiency virus-1 (HIV-1) attachment factor and promotes efficient infection in trans of cells that express CD4 and chemokine receptors. We have identified another gene, designated here as DC-SIGN2, that exhibits high sequence homology with DC-SIGN.
