Study design

Mixed methods study including quantitative data analysis and qualitative analysis of semi-structured interviews.

Objectives

Utilizing information and communication technology can facilitate professional communication within health care on a global scale. This study aimed to identify the educational and peer-to-peer communication needs of craniomaxillofacial (CMF) surgeons across the globe, determine preferred modes of communication, and assess technological and other barriers to online education and peer-to-peer communication.

Methods

We performed semi-structured videoconference interviews of 92 CMF surgeons from around the globe, with the largest number in the Asia/Pacific region, the Middle East, and Latin America. We triangulated quantitative summaries with qualitative themes to improve validity and enable a more comprehensive understanding of participant perspectives.

Results

The interviews revealed 3 main areas of technology use: new surgical technology, technology that enables information exchange, and communication technology. When asked about technology and communication platforms used in the course of their work, 33 participants (36%) mentioned PubMed or other journal-related sites; 25% recalled using YouTube as a resource; 23% described conducting internet searches using Google or other search engines; 21% used WhatsApp groups; and 11% used closed Facebook groups.

Conclusion

CMF surgeons embraced communication technologies that allowed them to quickly obtain knowledge especially on new surgical technology, discuss cases on demand, and maintain strong communication with their global peers.

Background

The risk of developing latent tuberculosis infection (LTBI) associated with cooking with solid fuels is unknown. This study examined the relationship between household fuel uses and LTBI in adults living in Nepal, a country with a high incidence of tuberculosis.

Methods

Participants were 1088 adults aged 18-70 years, members of the control group of a population-based case-control study of pulmonary TB (PTB) in people without previous TB, living in Kaski and neighboring districts of Nepal. Participants were interviewed in their homes with a standardized questionnaire. Blood samples were tested for LTBI using an interferon-gamma release assay. Multivariate unconditional logistic regression was used to examine associations between household fuel sources and LTBI.

Results

The overall prevalence of LTBI in the study population was 36%. Using liquefied petroleum gas (LPG) as the baseline cooking fuel type, the adjusted odds ratio (aOR) for using a primary wood cookstove was 1.13 (95%CI: 0.73,1.77) for all participants and, in women only, 1.14 (0.62, 2.09). Corresponding figures for biogas stoves were 0.64 (0.34,1.20) and 0.59 (0.24,1.45), respectively. Household sources of air pollution positively associated with LTBI included traditional oil lamps (diyos) used during power outages, for which the aOR in all participants was 2.53 (1.20, 5.31), although the number of users was small. Use of candles for lighting was also associated with increased risk of LTBI among men (aOR = 1.61, 95% CI:1.01, 2.56).

Conclusions

No association was found between use of wood for cooking and LTBI. However, there was some evidence that biogas cookstoves were associated with reduced odds of LTBI. Some exposures at the time of actual infection will have been different than the current exposures used in the analysis, biasing results towards the null. Results are sufficient for the use of diyos to be discouraged for lighting purposes. Overall, results suggest that household cooking fuel use is likely to have more effect on moving from the infected state to PTB than on becoming infected with the M. tuberculosis complex. Further research, including longitudinal studies with serial LTBI testing would be useful to more accurately assess the relationships between exposures and infection.

Background

Dietary acculturation is the process by which diet and dietary practises from the environment of origin are retained or changed and/or those prevalent in a new environment are adopted. Despite rapid population growth the U.S., knowledge gaps exist on characterising dietary acculturation among Asian American, Native Hawaiian, and Pacific Islander communities (AANHPI). This study characterise dietary patterns in a sample representative of AANHPI on key demographic characteristics.

Methods

Data were from a 2013-2014 population-based case-control study in the San Francisco Bay Area, U.S. Survey items were adapted from dietary acculturation scales developed for AANHPI populations. Validated measures assessed social capital, social standing, discrimination and immigration experiences. A principal components factor analysis was conducted to characterise dietary patterns of acculturation.

Results

Three dietary patterns were identified: "Asian," "Western," and a distinct "Multicultural" factor. Respondents reporting a high-Asian diet tended to also report smaller social networks, higher levels of stress, and, among those born outside of the U.S., an educational standing that was better before immigration. Respondents reporting a high-Western diet tended to also report the highest level of discrimination. Those reporting a high-Multicultural diet tended to report higher neighbourhood collective efficacy.

Conclusions

The finding of a distinct "Multicultural" factor beyond the typical "Asian" and "Western" factors may reflect the multidirectional relationships between culture, diet, and dietary behavior, in which origin and destination cultures interact in complex ways and where foods from multiple ethnicities intermix.
