The Mauli Ola Study: A Unique Academic-Community Partnership With MA'O Organic Farms to Understand and Address Health Inequities Among Native Hawaiians and Other Pacific Islanders in Hawai'i.

Indigenous peoples, including Native Hawaiians and Pacific Islanders (NHPIs), experience significant cardiometabolic health disparities arising in large part from rapid changes to their diets and food systems. Innovative food sovereignty initiatives led by NHPIs are needed to address these disparities. This article describes a community-based participatory research study that incorporates social and biological measures to examine the impact of an Indigenous-led land-based food sovereignty youth leadership program on health disparities among NHPI youth in Hawai'i. Grounded in the Indigenous knowledge that holistic health and wellbeing of people is inseparable from that of the environment and to counter rampant food insecurity in their community of Wai'anae, O'ahu, MA'O Organic Farms developed a Youth Leadership Training (YLT) program that offers education, nutrition, physical activity, and access to health care. The program also engages YLT interns and their social networks in health education and research in the ongoing Mauli Ola study. Preliminary data from this study affirm the need to address the disproportionately high rates of obesity, type 2 diabetes mellitus (T2D), and poor mental health conditions among young NHPIs in the Wai'anae community, and how the YLT program may provide an effective approach to address this need. Our unique academic-community partnership underscores the importance of social and biomedical research to understand health disparities in the NHPI population, which present novel avenues to enable disease prevention. The outcomes of the Mauli Ola study may serve as a valuable model for health disparities research while leveraging ongoing social programs that support Indigenous food sovereignty.

Spontaneous emulsification induced by nanoparticle surfactants.

Microemulsions, mixtures of oil, water, and surfactant, are thermodynamically stable. Unlike conventional emulsions, microemulsions form spontaneously, have a monodisperse droplet size that can be controlled by adjusting the surfactant concentration, and do not degrade with time. To make microemulsions, a judicious choice of surfactant molecules must be made, which significantly limits their potential use. Nanoparticle surfactants, on the other hand, are a promising alternative because the surface chemistry needed to make them bind to a liquid-liquid interface is both well flexible and understood. Here, we derive a thermodynamic model predicting the conditions in which nanoparticle surfactants drive spontaneous emulsification that agrees quantitatively with experiments using Noria nanoparticles. This new class of microemulsions inherits the mechanical, chemical, and optical properties of the nanoparticles used to form them, leading to novel applications.

No evidence for long-term carrier status of pigs after African swine fever virus infection.

This study targeted the assessment of a potential African swine fever virus (ASFV) carrier state of 30 pigs in total which were allowed to recover from infection with ASFV "Netherlands'86" prior exposure to six healthy sentinel pigs for more than 2 months. Throughout the whole trial, blood and swab samples were subjected to routine virological and serological investigations. At the end of the trial, necropsy of all animals was performed and viral persistence and distribution were assessed. Upon infection, a wide range of clinical and pathomorphological signs were observed. After an initial acute phase in all experimentally inoculated pigs, 66.6% recovered completely and seroconverted. However, viral genome was detectable in blood samples for up to 91 days. Lethal outcomes were observed in 33.3% of the pigs with both acute and prolonged courses. No ASFV transmission occurred over the whole in-contact phase from survivors to sentinels. Similarly, infectious ASFV was not detected in any of the tissue samples from ASFV convalescent and in-contact pigs. These findings indicate that the suggested role of ASFV survivors is overestimated and has to be reconsidered thoroughly for future risk assessments.

Evaluation of blowfly larvae (Diptera: Calliphoridae) as possible reservoirs and mechanical vectors of African swine fever virus.

In 2014, highly virulent African swine fever virus (ASFV) was introduced into the Baltic States and Poland, with new cases being reported almost every week from wild boar and also from domestic pigs. Contrary to initial predictions that the disease would either die out due to the high virulence of the virus strain or spread rapidly in westerly direction, the infection became endemic and spread slowly. The unexpected disease epidemiology led to the hypothesis that hitherto unconsidered factors might contribute to virus persistence and dispersal. To check whether arthropod species feeding and developing on infected carcasses might be involved, larvae of two commonly found blowfly species, Lucilia sericata and Calliphora vicina, were experimentally bred on ASFV-infected spleen tissue. After different time intervals, developing larvae and pupae were tested for infectious virus and viral DNA. By qPCR, contamination of the blowfly larvae and pupae with ASFV-DNA could be demonstrated even after several washing steps, proving the uptake of virus during feeding in the larval stage. However, infectious virus could never be isolated. By contrast, the larvae appeared to have inactivated ASFV in the offered tissue, which might be explained by the known anti-biotic effect of salivary secretions. It is concluded that immature blowfly stages do not play a relevant role as reservoirs or mechanical vectors of ASFV.

Biological characterization of African swine fever virus genotype II strains from north-eastern Estonia in European wild boar.

Due to its impact on animal health and pig industry, African swine fever (ASF) is regarded as one of the most important viral diseases of pigs. Following the ongoing epidemic in the Transcaucasian countries and the Russian Federation, African swine fever virus was introduced into the Estonian wild boar population in 2014. Epidemiological investigations suggested two different introductions into the southern and the north-eastern part of Estonia. Interestingly, outbreak characteristics varied considerably between the affected regions. While high mortality and mainly virus-positive animals were observed in the southern region, mortality was low in the north-eastern area. In the latter, clinically healthy, antibody-positive animals were found in the hunting bag and detection of virus was rare. Two hypotheses could explain the different behaviour in the north-east: (i) the frequency of antibody detections combined with the low mortality is the tail of an older, so far undetected epidemic wave coming from the east, or (ii) the virus in this region is attenuated and leads to a less severe clinical outcome. To explore the possibility of virus attenuation, a re-isolated ASFV strain from the north-eastern Ida-Viru region was biologically characterized in European wild boar. Oronasal inoculation led to an acute and severe disease course in all animals with typical pathomorphological lesions. However, one animal recovered completely and was subsequently commingled with three sentinels of the same age class to assess disease transmission. By the end of the trial at 96 days post-initial inoculation, all animals were completely healthy and neither virus nor viral genomes were detected in the sentinels or the survivor. The survivor, however, showed high antibody levels. In conclusion, the ASFV strain from north-eastern Estonia was still highly virulent but nevertheless, one animal recovered completely. Under the experimental conditions, no transmission occurred from the survivor to susceptible sentinel pigs.

[Secondary vesico-ureteral reflux in the adult age]. / Sekundärer vesiko-ureteraler Reflux im Erwachsenenalter.

The transurethral dehiscence of the ostium is a therapeutic method which causes the spontaneous passage of incarcerated intramural ureteroliths. However, it may be performed only in the centre of the roof of the ureter to a maximum length of 0.5 cm. With lateral indentation the antireflux principle of the ostia of the ureters is abolished by damaging the reins of the intravesical musculature of the ureters. An asymptomatic reflux necessarily becomes a reflex disease, when it is complicated by an infection of the urinary tract. In secondary vesico-ureteral reflux by dehiscence of the ostium at adult age the indication to the operative treatment shall be made narrowly, since with the sanation of the infection of the urinary tract the reflux often disappears.

The metabolism of ethynodiol diacetate by rat and human liver.

PIP: Ethynodiol diacetate is metabolized by both rat and human liver to a number of intermediary metabolites. The biotransformation reaction involved in the in vitro metabolism of ethynodiol diacetate include deacetylation, saturation of ring A, aromatization of ring A, formation of a 3-ketone and a delta-6 bond formation. The absolute structure of these metabolites are presented. The intermediary metabolites of ethynodiol diacetate undergo further biotransformation to more polar end products. The failure to hydrolyze the polar metabolites with either sulfatases or beta-glucuronidases suggests that this fraction consists mainly of polyhydroxylated steroids.^ieng
