Background: Tuberculosis (TB) and depression are highly comorbid and linked to higher rates of death and disability. Several evidence-based treatments for depression have been successfully implemented in low- and middle-income countries, but more knowledge is needed on how to bring these innovations to scale within complex 'real world' public health systems.
Objective: To explore whether the principles of social network analysis could be used to enhance receptivity to integrating depression treatment into primary care for individuals with and without TB in Brazil.
Culture and social structure are not separated analytical domains but intertwined phenomena observable in personal networks. Drawing on a personal networks dataset of migrants in the United States and Spain, we show that the country of origin, a proxy for diverse languages and cultural institutions, and religion may be predicted by specific combinations of personal network structural measures (closeness, clustering, betweenness, average degree, etc). We obtain similar results applying three different methods (a multinomial logistic regression, a Random Forest algorithm, and an artificial neural network).

Methods: We used a self-report survey to collect egocentric social network data from 107 caregivers of pediatric cancer patients and calculated descriptive statistics to examine cancer-related support network composition, function, and structure. We then ran logistic regressions to examine the relationships between network characteristics and overall satisfaction with social support.

Purpose: Smartphone-enabled micro-temporal data collection has potential to increase reliability, validity, and feasibility of participant-reported data and is a promising strategy for pediatric oncology supportive care and quality-of-life research. Given the demands of pediatric cancer caregiving, we sought to understand the feasibility and acceptability of smartphone data collection that included short surveys administered daily for 14 days via text message link.
Methods: We recruited pediatric cancer caregivers, whose children (ages 0-18 years) were on active treatment, to complete a 14-day daily survey study via smartphone.
Otitis media (OM) disease is a common cause of hearing loss that is primarily the result of middle ear infection. At present, our understanding of the mechanisms leading to OM is limited due to the lack of animal models of OM with effusion (OME). Here, we report that the mice with genetic otitis media one (gom1) mutants are prone to OM.

African Americans are understudied for depression-related phenotypes despite widespread racial disparities. In our study of African Americans, we integrated information on psychosocial stressors with genetic variation in order to better understand how these factors associated with depressive symptoms.

The compound effects of sexual and drug-related risk merit a systematic literature review to grant a better understanding of their role in HIV/STI transmission. The current review synthesizes the results of 21 studies conducted in multiple cultural settings.

Commentators have pointed to different factors which contribute to this trend, including the specialization of science and growing need for diversity of interest and expertise areas in a scientific team. Very few studies, however, have precisely evaluated how the diversity of interest topics between researchers is related to the emergence of collaboration.

Research indicates that there are both genetic and sociocultural risk factors for hypertension. Racial disparities in hypertension also likely involve genetic and sociocultural factors, but the factors may interact and manifest differently across racial groups.

The current study examines the network properties as well as the demographic and behavioral factors associated with drug use among female sex workers (FSWs) in southern China. We collected survey data (n = 175) in the Hainan province during our 26 months of ethnographic fieldwork in China.

Androgen receptor (AR) is expressed in monocytes/macrophages, which are resident in key metabolic tissues and influence energy metabolism in surrounding cells. Male mice bearing a cell-specific knockout of the AR in monocytes/macrophages (M-ARKO) were generated to determine whether selective loss of androgen signaling in these cells would lead to altered body composition.

This paper proposes a new method to (1) Identify collaborative communities in longitudinal scientific networks, and (2) Evaluate the impact of specific research institutes, services or policies on the interdisciplinary collaboration between these communities. First, we apply community-detection algorithms to cross-sectional scientific collaboration networks and analyze different types of co-membership in the resulting subgroups over time.

It has been long held that APOBEC1-mediated editing activity is dependent on the RNA binding protein A1CF. The function of A1CF in adult tissues has not been reported because a previously reported null allele displays embryonic lethality.

Purpose: This study sought to characterize social networks and participation with others for 36 youth, ages 11 to 16 years, with (n = 19) and without (n = 17) learning disability, attention disorder, or high-functioning autism.
Method: Social networks were measured using methods of personal network analysis.

However, access to health care clinics and other modern services can have an impact on the distribution of medical ethnobotanical knowledge. Many factors have been shown to be associated with distributions in this type of knowledge.

In a project supported by the University of Florida (UF) Clinical and Translational Science Institute, we used VIVO, a semantic-web research networking system, to extract the social network of scientific collaborations on publications and awarded grants across all UF colleges and departments. Drawing on the notion of network interventions, we designed an alteration program to add specific edges to the collaboration network, that is, to create specific collaborations between previously unconnected investigators.

Cyclin D genes regulate the cell cycle, growth and differentiation in response to intercellular signaling. While the promoters of vertebrate cyclin D genes have been analyzed, the cis-regulatory sequences across an entire cyclin D locus have not. Doing so would increase understanding of how cyclin D genes respond to the regulatory states established by developmental gene regulatory networks, linking cell cycle and growth control to the ontogenetic program.

Personal networks of women who entered residential treatment had more substance users, more people with whom they had used alcohol and/or drugs, and fewer people from treatment programs or self- help groups than personal networks of women who entered intensive outpatient treatment. By 12 months post treatment intake, network composition improved for women in residential treatment; however, concrete support was still lower and substance users are still more prevalent in their networks.

In this case, we examine standard and novel predictors of risk perception in seven sites among communities affected by a flood in Mexico (one site) and volcanic eruptions in Mexico (one site) and Ecuador (five sites). We conducted more than 450 interviews with questions about how people feel at the time (after the disaster) regarding what happened in the past, their current concerns, and their expectations for the future.

Within the vestibular system, linear acceleration and gravity are detected by the saccule and utricle. Resting above the neurosensory epithelia of these organs are otoconia, minute proteinaceous and crystalline (calcite) inertial masses that shift under the physical forces imparted by linear movements and gravity.
