"That makes all the difference": Aboriginal and Torres Strait Islander health-seeking on social media

ISSUE ADDRESSED

Little is known about the complex relationships between Australian Indigenous people's use of social media and "health-seeking" - seeking help for issues related to health and well-being. This paper has emerged from a broader sociological research project focusing on the help-seeking and help-giving practices of Aboriginal and Torres Strait Islander people on social media, specifically aiming to unlock its potential to create vital and creative connections between help-seekers and help-givers.

METHODS

Semi-structured interviews were conducted with 52 Indigenous Facebook users from five sites across Australia.

RESULTS

The use of grounded theory and Indigenous-centred methodologies for analysis showed clearly that users draw on the connections made possible through Facebook to health-seek. We identify five primary health-seeking strategies that differ in form, purpose and directness: soliciting health-related information, gaining emotional support, producing social health-seeking collectives, engaging in motivational and "eudaimonic" content, and connecting with formal health sources.

CONCLUSION

While far from being a panacea to health disparities, these findings show that Facebook does provide unique opportunities for many Indigenous help-seekers and help-givers in times of need. SO WHAT?: Social media offers pathways for health-seeking both beyond and outside the dominant western biomedical models of public health promotion. These already-existing pathways should be considered by people working on social media public health promotion campaigns for Aboriginal and Torres Strait Islander people.

Protection against oral and gastrointestinal diseases: importance of dietary nitrate intake, oral nitrate reduction and enterosalivary nitrate circulation

Over the last 20 years, dietary nitrate has been implicated in the formation of methemoglobin and carcinogenic nitrosamines in humans. This has led to restrictions of nitrate and nitrite levels in food and drinking water. However, there is no epidemiological evidence for an increased risk of gastric and intestinal cancer in population groups with high dietary vegetable or nitrate intake. A reevaluation of our currently very negative perception of dietary nitrates comes from recent research into the metabolism and enterosalivary circulation of nitrate in mammals. These studies showed that nitrate is converted to nitrite in the oral cavity that then "fuels" an important mammalian resistance mechanism against infectious diseases. Moreover, there is now evidence that the conversion of nitrate into oxides of nitrogen prevents the formation carcinogenic nitrosamines.

Antimicrobial effect of acidified nitrite on gut pathogens: importance of dietary nitrate in host defense

Dietary intake of nitrate generates salivary nitrite, which is acidified in the stomach, leading to a number of reactive intermediates of nitrogen, among which are the potentially carcinogenic N-nitrosamines. Acidified nitrite, however, also has antimicrobial activity which coincides with the formation of nitric oxide. The present study examines the antimicrobial effect in vitro of acidified nitrite on Salmonella enteritidis, Salmonella typhimurium, Yersinia enterocolitica, Shigella sonnei, and Escherichia coli O157. First-order regression plots showed a linear inverse relationship of log-transformed proton and nitrite concentrations with MICs and MBCs after 30 min, 2 h, and 24 h of exposure (P < 0.001 for all antibacterial activities). Susceptibility to the acidified nitrate solutions ranked as follows: Y. enterocolitica > S. enteritidis > S. typhimurium = Shigella sonnei > E. coli O157 (P < 0.05). Addition of SCN-, but not that of CI-, increased the antibacterial activity (paired t testing, P < 0.001). Generation of salivary nitrite from dietary nitrate may provide significant protection against gut pathogens in humans.

The development of air medical services in Czechoslovakia

The Czechoslovakian system of centralized dispatch of all emergency medical services prevents competition between ground ambulances and air medical services. Although this program is less than two years old, remarkable progress has pushed Czechoslovakia to the forefront of modern-day air medical transport. However, the future of Czechoslovakian air medical transport will require the acquisition of better-performing EMS helicopters and accessibility to medical equipment using Western technology. As with all current United States helicopter EMS systems, Czechoslovakia will face many of the financial considerations required in funding this extensive and elaborate project.

Sampling the fetoplacental circulation. III. Combined laparoscopy-fetoscopy in the pregnant macaque for hemoglobin identification

To demonstrate increased technical experience with fetoscopy and fetal blood sampling, two groups of macaques were compared to control animals. Group 2 had a perinatal mortality rate that was not significantly different from that of the control group. A 2.7 mm. Hopkins rod lens endoscope encased in an eccentric cannula, 3.8 mm. outside diameter, was used. When compared to the earlier test group (Group 1), the later test group (Group 2) showed greater adequacy of the fetal blood sample for laboratory analysis (P less than 0.01). Anthropometric and hematologic data collected at term births compared favorably in test and control groups, with the exception of the white blood cell count, which was significantly lower with fetoscopy (P less than 0.01). This is the first report of experimental fetoscopy with the use of a control group to provide precise data to aid in clarification of the ethical issues yet unresolved in this technology.

Sampling the fetoplacental circulation. II. Combined laparoscopy-fetoscopy in the pregnant ovine

Induction of pneumoperitoneum, laparoscopy, and intrauterine endoscopy (fetoscopy) were successfully accompished in 23 pregnant sheep at 45 to 60 days' gestational age. The fetoscope, a conventional 2.7 mm. Hopkins straightforward wide-angle telescope (Stortz 27018A) encased in a prototype 3.1 mm. eccentric cannula, incorporates a 25 gauge needle channel. Multiple pregnancy was encountered in 11 animals. Forty-two separate fetoscopic trials were accomplished; a fetoplacental blood sample was obtained in 52 per cent of the trials. A mean interval of 19 +/- 9 days (+/- S.D., range 6 to 37 days) was allowed between fetoscopy trials. Fetal deaths occurred in nine animals (39 per cent). We believe that laparoscopy permits preselection of the proposed fetoscopy puncture site and will permit the operator to thereby avoid the placenta and/or uterine vessels.

Sampling the fetoplacental circulation. I. The pregnant ovine

Intrauterine endoscopy (fetoscopy) was successfully accomplished in 26 specially prepared pregnant sheep at 85 to 110 days' gestational age, with the use of a conventional 2.7 mm. Hopkins straightforward wide-angle telescope (Stortz 27018A) encased in a prototype 3.1 mm. eccentric cannula which incorporates a 25 gauge needle channel. Fetal blood was aspirated in 12 lambs. Twenty-five animals were followed throughout the remainder of pregnancy: nine (36 per cent) aborted within three days-three weeks after endoscopy. The pregnant ovine appeared to be a useful experimental animal model for the development of an intrauterine endoscopy technique.
