A new atherinid fish, Doboatherina palauensis, is described based on the holotype and 31 paratypes, 36–51 mm in standard length, collected from the marine lakes and outer lagoon in Mecherchar Island, Republic of Palau. The new species can be distinguished from all congeners by a short, blunt ascending process of the premaxilla (height about twice maximum width), premaxilla with a single lateral process, posterior upper margin of dentary with a small process, palatine toothed, no crenulation along posterior margin of lateral and predorsal scales, smaller eye (diameter 9.2–11% of standard length), 37–39 midlateral scales, 38–41 total vertebrae, narrower midlateral band (about 1/2 width of midlateral scale, its upper and lower margins not reaching to upper and lower margins of midlateral scale row at the level of anal-fin origin, respectively). The new species resembles Doboatherina aetholepis (Kimura, Iwatsuki and Yoshino 2002), Doboatherina bleekeri (Günther 1861), Doboatherina valenciennei (Bleeker 1854) and Doboatherina woodwardi (Jordan and Starks 1901) in sharing a comparatively slender body in the genus Doboatherina. The former is distinguishable from D. aetholepis by having only a short spatular outgrowth on posterior margin of predorsal and/or interdorsal scales or almost lacking the outgrowth (vs. a long spatular outgrowth on posterior margin of most predorsal and interdorsal scales in D. aetholepis) and narrower midlateral band (lower margin not reaching to lower margin of midlateral scale row vs. reaching), from D. bleekeri and D. valenciennei by lacking crenulated lateral and predorsal scales (vs. having crenulated lateral and/or predorsal scales) and a single lateral process on premaxilla (vs. two processes), and from D. woodwardi by having lower ascending process (height about twice maximum width vs. three times) and a single lateral process on premaxilla (vs. two processes). Doboatherina bleekeri has more numerous total vertebrae (42–47) than D. palauensis (38–41). [ABSTRACT FROM AUTHOR]

Literature about Indigenous health has dramatically increased over the past few years, which has made it difficult to stay current--this is a good thing. This uptick indicates that this work is getting attention it deserves. However, every so often a collection comes along that provides an essential overview of the work being done, and Global Indigenous Health: Reconciling the Past, Engaging the Present, Animating the Future is one such book. It examines the impacts and effects of health determinants on Indigenous Peoples from across the globe, including Micronesia, Alaska, and Canada. [ABSTRACT FROM AUTHOR]

Background and Purpose: Oceania, comprising the regions Australasia, Melanesia, Micronesia, and Polynesia, is home to 42 million living in 8.5 million square kilometres of land. This paper comprises a review of the epidemiology of stroke in countries in this region. Methods: Information on epidemiology of stroke in Oceania was sought from data from the Global Burden of Disease (GBD) study (incidence, mortality, incidence:mortality ratio [IMR], prevalence, disability-adjusted life-years [DALYs] lost due to stroke, and subtypes), World Health Organization (WHO) (vascular risk factors in the community), and PubMed (incidence, prevalence, and stroke subtypes). Data were analyzed by region to allow inter-country comparison within each region. Results: In 2010, age- and sex-standardized stroke mortality rates were lowest in Australasia (29.85–31.67/100,000) and highest in Melanesia and Micronesia (56.04–187.56/100,000), with wide ranges especially in Melanesia. Incidence rates were lowest in Australasia (101.36–105.54/100,000), similarly high elsewhere. Standardized IMR (0.98–3.39) was the inverse of the mortality rates and mirrored the prevalence rates (202.91–522.29/100,000). DALY rates (398.22–3,781.78/100,0000) mirrored the mortality rates. Stroke risk factors show a variable pattern – hypertension is generally the most common medical risk factor among males (18.0–26.6%), while among females, diabetes mellitus is the most common in Micronesia and Polynesia (21.5–28.4%). Among the lifestyle factors, current smoking is the most common in Melanesia among males, while obesity is generally the most common factor among females. Ischaemic stroke comprises 70% of stroke subtypes. Trend data show significant falls in standardized mortality rates and DALYs in most regions and falls in incidence in almost all countries. There is significant economic impact, particularly due to young strokes; some ethnicities are at higher risk than others, for example, Maoris and Pacific Islanders. Conclusions: Stroke is a major healthcare problem in Oceania. Variations in stroke epidemiology are found between countries in Oceania. Data are lacking in some; more research into the burden of stroke in Oceania is needed. With the expected increase in life expectancy and vascular risk factors, the burden of stroke in Oceania will likely rise. Some of the disparities in stroke burden may be addressed by great investment in healthcare. [ABSTRACT FROM AUTHOR]

Mangrove forests have adapted to sea level rise (SLR) increases by maintaining their forest floor elevation via belowground root growth and surface sediment deposits. Researchers use surface elevation tables (SETs) to monitor surface elevation change (SEC) in mangrove forests, after which this information is used to assess SLR resiliency or to dictate active forest management for vulnerable systems. This method requires significant investments in terms of time and human resources and is limited in the number of points it can measure per plot. We use a low‐cost, portable terrestrial laser scanning (TLS) system to assess SEC for three mangrove forests on Pohnpei Island (Federated States of Micronesia). Cloth simulation filtering was used for ground detection, after which results were refined by filtering points using angular orientation. Digital elevation models then were generated via kriging interpolation for data collected in 2017 and 2019, after which the heights of corresponding points were compared across years. Extreme elevation changes, due to disturbances such as footprints or fallen logs, were removed using interquartile range analysis. The TLS‐obtained average SEC ranged between −6.92 and +6.01 mm, which exhibited an average consistency of 72% when compared to simultaneously collected SET data (root mean square error = 1.36 mm). We contend that this approach represents an improvement over the manual method, where very few points typically are used, that is, ≅ 36 points vs. ≅ 30,000 points in the case of TLS, and could contribute to improved monitoring and management of these rapidly changing forest environments.

BackgroundCommunity-based participatory research (CBPR) holds the promise of improving the planning, conduct, and long-term translation of research findings into community settings.ObjectivesThis 2-year, exploratory study applied CBPR structures and processes to the identification of individual, cultural and community factors associated with obesity among Pacific Islander (PI) youth in Southern California.MethodsWe describe the CBPR principles and strategies used by a community-university partnership to develop, implement, and report on the findings from assessments of obesity, physical activity, and nutritional intake among PI youth.ResultsAlthough CBPR planning processes led to successes in community-based youth recruitment and retention, we learned key lessons regarding implementation of tailored assessment protocols, often involving problems arising from the university side of the CBPR collaborative.ConclusionCBPR has its strengths and limits; more studies are needed that report on processes to increase our understanding of how to balance research rigor with community sustainability.

The U.S. Department of Defense is in the process of restructuring military assets in the Pacific Basin that includes moving more troops to Guam. As a result of this process, the potential risk of vertebrate invasive species may increase across Micronesia. We identified the pathways through which goods and materials are moved throughout the Pacific basin and then developed a list of the most likely invasive vertebrates that could be moved in these pathways. We reviewed the available literature, interviewed experts, and evaluated pathways according to a fixed set of criteria to determine the risk of the pathway to transport invasive species. Some of the potentially high-risk pathways are military and commercial aircraft and vehicles, mail, shipping containers, and aquaculture. The following are species that may spread or become established in the Pacific without the implementation of measures to reduce risk: brown tree snake, habu, Asian beauty snake, common wolf snake, anole, gecko, coqui frog, cane toad, red-vented bulbul, Indian myna, and Indian mongoose.

Sedimentation and overfishing are important local stressors on coral reefs that can independently result in declines in coral recruitment and shifts to algal-dominated states. However, the role of herbivory in driving recovery across environmental gradients is often unclear. Here we investigate early successional benthic communities and coral recruitment across a sediment gradient in Palau, Micronesia over a 12-month period. Total sedimentation rates measured by 'TurfPods' varied from 0.03 ± 0.1 SE mg cm−2 d−1 at offshore sites to 1.32 ± 0.2 mg cm−2 d−1 at inshore sites. To assess benthic succession, three-dimensional settlement tiles were deployed at sites with experimental cages used to exclude tile access to larger herbivorous fish. Benthic assemblages exhibited rapid transitions across the sediment gradient within three months of deployment. At low levels of sedimentation (less than 0.6 mg cm−2 d−1), herbivory resulted in communities dominated by coral recruitment inducers (short turf algae and crustose coralline algae), whereas exclusion of herbivores resulted in the overgrowth of coral inhibitors (encrusting and upright foliose macroalgae). An 'inducer threshold' was found under increasing levels of sedimentation (greater than 0.6 mg cm−2 d−1), with coral inducers having limited to no presence in communities, and herbivore access to tiles resulted in sediment-laden turf algal assemblages, while exclusion of herbivores resulted in invertebrates (sponges, ascidians) and terrestrial sediment accumulation. A 'coral recruitment threshold' was found at 0.8 mg cm−2 d−1, below which net coral recruitment was reduced by 50% in the absence of herbivores, while recruitment was minimal above the threshold. Our results highlight nonlinear trajectories of benthic succession across sediment gradients and identify strong interactions between sediment and herbivory that have cascading effects on coral recruitment. Local management strategies that aim to reduce sedimentation and turbidity and manage herbivore fisheries can have measurable effects on benthic community succession and coral recruitment, enhancing reef resilience and driving coral recovery.

While undertaking a botanical survey of the Andersen Air Force Base on Guam (Mariana Islands) in 1994, botanists from the National Tropical Botanical Garden collected an unusual suffrutescent, nonaromatic member of the Lamiaceae family growing on limestone cliffs in the northeastern part of the island. Based on morphology and molecular data (trnLF, matK), it was determined to belong to the genus Pogostemon Desf., a genus previously unknown from the Micronesian, Melanesian, and Polynesian region. Moreover, the analysis also showed that it was not conspecific with P. cablin (patchouli), and of the species available to include in the phylogenetic analyses it is sister to P. hirsutus, a species from India and Sri Lanka. Differing from its congeners by its large, loose inflorescence 2.5-5 cm wide and up to 7 cm wide in fruit, it is here illustrated and described as a new species, Pogostemon guamensis Lorence & W.L. Wagner and its habitat and conservation status are discussed. [ABSTRACT FROM AUTHOR]

Background: Oral cavity carcinomas individually are the fifth-leading cause of overall cancer mortality in the Northern Mariana Islands, which is likely a representative statistic for many other betel-nut-endemic Pacific islands. Factors associated with survival have been minimally evaluated in this region. The purpose of this study is to further characterize oral cavity carcinoma outcomes and associated prognostic factors in the United States commonwealth of the Northern Mariana Islands (CNMI). Methods: A single-institution retrospective review was undertaken for 81 patients diagnosed with head and neck cancers at the CNMI's only regional hospital complex from 2005 to 2019. A subset of patients diagnosed with oral cavity carcinoma was further evaluated for survival outcomes. Cox proportional hazard regressions were performed to evaluate for variables associated with survival. Results: A majority of patients had cancer of the oral cavity (64/81, 79%). Fifty-five of these patients had sufficient data for review. The average age at the time of diagnosis was 48 and over half were diagnosed with stage IV disease (29/55, 53%). Five-year overall survival (OS) was 49.5% (95% CI, 33.3-63.7%). Factors associated with worse OS were lymph node metastases at presentation (P =.031), higher overall stage (III or IV vs I or II, P =.016), and higher T-stage (III or IV vs I or II, P =.027). Those who used betel nut were diagnosed at a significantly younger age than those who did not (47.2 vs 55.4, P =.001). Conclusions: The head and neck cancer burden in the CNMI is dominated by betel nut related oral cavity disease that is characterized by delayed presentations in younger patients and decreased OS. Future studies are indicated to improve health literacy as well as to investigate the potential for screening programs. [ABSTRACT FROM AUTHOR]

Access to cesarean delivery is vital for quality obstetrical care, but the procedure can increase maternal mortality, morbidity, and complications in subsequent deliveries. The objective of this study was to describe obstetrician–gynecologists' (OB-GYNs) perspectives on labor and delivery care for Micronesian women in Hawai'i and possible factors contributing to higher cesarean delivery rates among that racial/ethnic group. The Framework Method guided the analysis of 13 semi-structured interviews with OB-GYNs. Study results indicated that OB-GYNs were more likely to attribute racial/ethnic differences in mode of delivery to challenges resulting from nonmedical factors, particularly communication and negative attitudes toward Micronesian patients, than to medical risk factors. In this study, we explored aspects of care that cannot be captured in medical charts or clinical data, but may impact health outcomes for this population. The findings could help improve care for Micronesian women, with lessons applicable to other racial/ethnic minority groups. [ABSTRACT FROM AUTHOR]

Length–weight relationships (LWRs) are a fundamental tool for the non-intrusive determination of biomass, a unit of measure that facilitates the quantification of ecosystem and fisheries productivity. LWRs have been defined and broadly applied for many marine species across a range of ecosystems, especially regarding fishes. However, LWRs are yet to be determined for the majority of marine taxa, particularly for small cryptic organisms that are difficult to census and poorly described. On coral reefs, the motile cryptofauna represent the greatest density and diversity of metazoan taxa that likely support critical steps in trophic pathways, but little empirical data exist beyond biodiversity assessments. We evaluated LWRs for 42 groups of motile cryptofauna across four microhabitats (live Acropora, live Pocillopora, dead branching coral and coral rubble) in Palau, Western Micronesia. We employed a robust methodology to determine LWRs by comparing the suitability of a series of linear, quadratic, polynomial and power models. Using the best-fit equations for each group, we provide the first documented LWRs for motile cryptofauna, namely at the level of family. LWRs were well fit (R2 > 0.90) for 45% of the groups and reasonable (R2 > 0.70) for 76%. The presence, size and weight of cryptofauna varied among microhabitats with the size distribution of 13 groups significantly influenced by habitat type. Establishment of these LWRs provides critical baseline information regarding an overlooked group on coral reefs, making population data on the cryptofauna more accessible to support future research aiming to characterise the roles of these taxa in ecosystem functioning and trophodynamics.

Accurate assessment of forest structure and biomass is hampered by extensive field measurements that are time-consuming, costly, and inefficient. This is especially true in mangrove forests that have developed complex above-ground root structures for stability and survival in the harsh, anaerobic, and reducing conditions of water-logged sediments. These diverse structures can differ even among similar species, providing complex three dimensional structures and making them difficult to accurately assess using traditional allometric methods. Terrestrial laser scanners (TLS) have been used widely in collecting forest inventory information in recent years, mainly due to their fine-scale, detailed spatial measurements and rapid sampling. In this work we detected stems and roots in TLS data from three mangrove forests on Pohnpei Island in Micronesia using 3D classification techniques. After removing noise from the point cloud, the training set was acquired by filtering the facets of the point cloud based on angular orientation. However, many mangrove trees contain above-ground roots, which can incorrectly be classified as stems. We consequently trained a supporting classifier on the roots to detect omitted root returns (i.e., those classified as stems). Consistency was assessed by comparing TLS results to concurrent field measurements made in the same plots. The accuracy and precision for TLS stem classification was 82% and 77%, respectively. The same values for TLS root detection were 76% and 68%. Finally, we simulated the stems using alpha shapes for volume estimation. The average consistency of the TLS volume assessment was 85%. This was obtained by comparing the plot-level mean stem volume (m3/ha) between field and TLS data. Additionally, field-measured diameter-at-breast-heights (DBH) were compared to the lidar-derived DBH using the reconstructed stems, resulting in 74% average accuracy and an RMSE of 7.52 cm. This approach can be used for automatic structural evaluation, and could contribute to more accurate biomass assessment of complex mangrove forest environments as part of forest inventories or carbon stock assessments.

The islands of the western Pacific have increasingly been portrayed by policymakers, military strategists, journalists, and scholars as places caught between a rising China and traditional powers such as the United States and their allies. In this article, however, we aim to challenge the geopolitical view of islands as 'falling' into the sphere of influence of one power or another. Specifically, we use an approach informed by assemblage theory to highlight the ways that islands in the Pacific simultaneously engage with multiple powers and their associated political, economic, and social influences. To ground our argument, we discuss two 'great power' schemes that aim to bring islands in the region into specific relational configurations: U.S. 'littoral defense lines' and China's Belt Road Initiative. We also include a brief case study of Chinese tourism investment in Yap Island (Wa'ab) in the Federated States of Micronesia (which is a state in 'free association' with the U.S.). Through these examples, we show how influence in the island Pacific is not a zero-sum game between foreign powers vying for hegemony. Instead, from an island perspective, residents and policymakers are attempting to weave together and navigate multiple foreign influences in ways that frustrate colonial and neocolonial logics of international relations.

To ensure standardized, quantitative and repeatable methodologies, marine ecologists have engineered a range of artificial units to survey benthic communities with varying designs depending on target taxa, life history stage and habitat. In tropical ecosystems, autonomous units have typically lacked microhabitat complexity (e.g. planar tiles), short‐term efficacy (<1 year deployment) and/or a truly standardized design to sample cryptobenthic diversity.Coral rubble is characterized by high microhabitat complexity, which is unresolved in sampling efforts. Yet, rubble can support the greatest density and diversity of metazoan taxa.We engineered RUbble Biodiversity Samplers (RUBS) as a dismantlable lightweight 3D‐printed model to standardize cryptobenthic biodiversity sampling.We demonstrate the effectiveness of RUBS with preliminary results from short‐term (1–14 days) deployments in Palau, Western Micronesia.RUbble Biodiversity Samplers uphold the microhabitat complexity inherent in coral rubble (~50% interstitial space) and provide an effective and efficient methodology to sample cryptobenthic fauna, which could be applied in comparative studies.The RUBS concept provides a platform for the broader implementation of 3D‐printed models in marine ecology to overcome issues of standardization regardless of habitat type.

Many low‐ and middle‐income countries are faced with a double burden of malnutrition characterized by a stagnating burden of undernutrition and an increasing prevalence of overweight and obesity often observed both at population and household levels. We used data from the 2017 National Integrated Child Health and Nutrition Survey in the Republic of the Marshall Islands to explore the prevalence of overweight mother‐stunted child pairs (mother–child double burden, MCDB). We used bivariate analysis, multivariate logistic regression, and multinomial logistic regression analysis to explore associations between child‐, maternal‐, and household‐level variables and both stunting and MCDB and other types of maternal–child pairs. Our results indicate that nearly three out of four mothers were overweight or obese and one in four households is home to an overweight mother with a stunted child. The risk of child stunting and of MCDB were largely associated with maternal characteristics of lower maternal height, maternal age at birth, years of education, and marital status and household economic status as measured by wealth index and number of household members. These findings support the growing body of evidence showing that the coexistence of high maternal overweight and child stunting (MCDB) has linked root causes to early life undernutrition that are exacerbated by the nutrition transition.

Introduction: Marshallese migrating to the United States encounter challenges in accessing health care. Previous literature has investigated Marshallese participants' perceptions of the barriers they face in accessing health care. For this study, health care providers managing the care of Marshallese patients were interviewed to understand the providers' perception of barriers that their Marshallese patients encounter. Methods: A qualitative research design was utilized to explore health care providers' perceptions of and experiences with the barriers faced by their Marshallese patients when accessing the US health care system. Results: The primary barriers identified were: (1) economic barriers; (2) communication challenges; (3) difficulty understanding and navigating the western health care system; and (4) structural and system barriers. Conclusion: This study provides insight on the barriers Marshallese patients face in accessing health care as well as the barriers providers face in delivering care to Marshallese patients. A better understanding of these barriers can help health care providers and educators to begin initiating improvements in the delivery of care to Marshallese patients. [ABSTRACT FROM AUTHOR]

We present a weight-length relation and use rapid and low-cost histological methods to generate preliminary reproductive parameters for Monotaxis grandoculis (Forsskål, 1775), based on specimens collected in Guam and Pohnpei [W = 0.033(FL)2.91]. We estimated female L50 at 30.0 cm FL and male L50 at 35.4 cm FL. The species is gonochoric. Overall and operational sex ratios were not significantly different from 1:1; however, among mature individuals, the proportion of females was an inverse function of length with no females > 33.5 cm FL but males to 44.5 cm FL. Batch fecundity was an exponential function of length but, because females were absent in the largest size classes, the highest per capita egg production was by individuals at 31.7 cm FL, only 71.2% of maximum observed specimen length. Boat-based creel surveys in Guam showed that the mean length of M. grandoculis in the catch decreased below both female and male L50 from 2010 to 2019, suggesting a significant decline in spawning stock biomass.

Terrestrial laser scanning systems are characterized by a sampling pattern which varies in point density across the hemisphere. Additionally, close objects are over-sampled relative to objects that are farther away. These two effects compound to potentially bias the three-dimensional statistics of measured scenes. Previous methods of sampling have resulted in a loss of structural coherence. In this article, a method of sampling is proposed to optimally sample points while preserving the structure of a scene. Points are sampled along a spherical coordinate system, with probabilities modulated by elevation angle and squared distance from the origin. The proposed approach is validated through visual comparison and stem-volume assessment in a challenging mangrove forest in Micronesia. Compared to several well-known sampling techniques, the proposed approach reduces sampling bias and shows strong performance in stem-reconstruction measurement. The proposed sampling method matched or exceeded the stem-volume measurement accuracy across a variety of tested decimation levels. On average it achieved 3.0% higher accuracy at estimating stem volume than the closest competitor. This approach shows promise for improving the evaluation of terrestrial laser-scanning data in complex scenes. [ABSTRACT FROM AUTHOR]

Background: To communicate research to the public, the National Cancer Institute developed the Health Information National Trends Survey (HINTS). However, as with most national health surveillance, including the Behavioral Risk Factor Surveillance System, HINTS data are not sufficient to address unique demographic subpopulations such as US Pacific Islanders (PIs). National sampling methods do not adequately reach participants from small, medically underserved populations.Aim: This study aims to document the cancer-relevant knowledge, attitudes, behaviors, and information-seeking practices of PIs in Hawaii (HI).Methods: We conducted a cross-sectional survey during 2017-2018 of Native Hawaiians, Chuukese, and Marshallese in HI using Respondent Driven Sampling (RDS) to recruit these geographically diffuse groups. The modified HINTS survey included questions about cancer knowledge, attitudes and behaviors, health communications, and cultural practices.Results: A total of 515 Native Hawaiians, 305 Chuukese, and 180 Marshallese completed the survey. Differences were found across a variety of cancer-related attitudes, knowledge, and behaviors. These groups also differed regarding acculturation, health locus of control, and trust in medical professionals. Native Hawaiians were significantly more acculturated (P=.0001) than Chuukese or Marshallese and more likely to smoke cigarettes (P=.0001). Among participants aged >50 years, we found no significant differences across ethnic groups (P=.30) for those completing a colon cancer screening (37%). However, only 27% were referred to screening by a physician.Conclusions: Cancer prevention programs are greatly needed for PIs in HI. This study provides knowledge concerning the efficiency of RDS to recruit participants, and the role of culture in communications influencing cancer risk behaviors, which may be generalizable to migrant PIs in the United States.

Wilhelm Knappe (1855–1910), the first German administrator (imperial commissioner) assigned to the newly acquired Marshall Islands in 1886, created a photo album with pictures, presumably taken by New Zealand photographer Thomas Andrew in the same year. There are at least three existing copies of these albums and a bundle of loose photographs identical to those in the album in question. At the time of Knappe's arrival in the Marshall Islands, Germany was still in the process of consolidating its newest colonial acquisition. The photographs show both Marshall Islanders untouched by Christian missions and colonial influence, and already 'civilized' Indigenous people from various atoll islands of the Ralik- and Ratak-group. The importance of this album results from the fact that it is one of the earliest pictorial records of the Marshall Islands and it probably represents the first documentation of German activities on the eastern Micronesian archipelago. This article highlights the history of the album and the photographs as well as their importance for a reconstruction of Marshall Islands' history in the late nineteenth century.

To continue the project of explicating Pacific values and worldviews, this paper focuses on correlative thinking in some of the cultural philosophies of the Pacific islands, especially Micronesia. Correlative thinking differs, in degree, from scientific and academic logic that emphasize the truth-value of statements. After examining aspects of correlative thinking in Bali and the Philippines, I extract some characteristics of Pacific philosophies from cultural practices, myths, and beliefs. Unlike William Alkire (Alkire, 1972), I find that Pacific islanders use correlative thinking, not dualism, to fill their canoes and baskets of wisdom, so that they can navigate between contemporary logic or scientific thinking, and their cultural knowledge systems and ways of reasoning.

Accidental dispersal of Micronesian voyaging canoes is well known. While most of this occurred within the archipelagos, some was further afield. A twelfth century Japanese report narrates the arrival of a boat of castaways to the Izu Islands (off Tokyo). This paper examines this narrative against the background of other documented long distance dispersal from Micronesia, such as vagrant saltwater crocodiles and a canoe drifting from Lamotrek to Shanghai (China).

This article is a historiographic overview of the conquest and evangelization of the Mariana Islands (XVII-XVIII centuries). Since the pioneering work of renowned scholars of Micronesian history, such as Marjorie G. Driver and Francis X. Hezel, historians, archaeologists and anthropologists have analyzed Jesuit missions not only as a complement to colonial power dynamics in the Asia-Pacific, but also as a privileged field for analyzing cross-cultural encounters. Faced with essentialist approaches that question the "aboriginal" character of the current CHamoru of the Marianas, other studies question their supposed disappearance, and appeal to their cultural continuity in historical time. It is also a small tribute to Marjorie G. Driver, pioneer in colonial studies on the Spanish presence in Micronesia, who left us on September 20, 2019, at the age of 95. [ABSTRACT FROM AUTHOR]

Achieving gender equality is a key component for improving global health, but how to do so remains a complex undertaking. Each community's experiences with gender inequality and vision for equality are historically and culturally specific, while also fitting larger global patterns. This is the case in Chuuk, Federated States of Micronesia, a group of islands suffering from the impacts of a long history integrating coloniser and locally formed patriarchal values. Chuukese women often see their roles as powerless and silent except when acting through women's groups. In recent decades, Chuukese women created an umbrella organisation for all women's groups, yielding more power to effect change. Derived from an ethnographic study of the Chuuk Women's Council (CWC), 1 focus group and 12 individual interviews were conducted with CWC members to explore women's experiences advancing gender equality on their terms. Findings demonstrate how the CWC lobbied for legal change, replaced inadequate health and social services, and changed community conversations about gender. The CWC received national and international resources, which became both supportive and disruptive to their efforts. Findings from this study have implications for global support of grassroots efforts to achieve gender equality, with lasting implications for gender equity in health. [ABSTRACT FROM AUTHOR]

Background: Obesity is a public health problem in Micronesia. The objective of the study was to assess obesity, the relationship between body mass index (BMI) and body fat percentage (BF%) among adults, and determine the appropriate BMI cut-points in Kiribati.Methods: A cross-sectional study was undertaken among 483 adults randomly selected from South Tarawa (ST) and Butaritari (BT). Weight, height, BF% and physical activity level (PAL) was measured using standard methods. Linear and quadratic regression analyses were conducted to assess the association between BF% and BMI whilst controlling for age and gender. Receiver operating characteristics (ROC) curve analyses were used to assess whether for the Kiribati population alternative BMI cut-off points for obesity are needed.Results: Approximately 75% of participants were obese using standard BMI and BF% cut-offs, with the highest prevalence observed in South Tarawa. BF% was significantly (p < 0.001) and positively associated with age (males, r = 0.78; females, r = 0.67; p < 0.001) and BMI. Based on ROC-curve analyses the BMI cut-offs for predicting high BF% among I-Kiribati people were 24.5 kg/m2 for males and 32.9 kg/m2 for females.Conclusions: In conclusion, the majority of adults in Kiribati were either obese or overweight and had high BF%. We suggest that ethnic-specific BMI cut-points to define obesity for the population of Kiribati may be more appropriate than the currently used international cut-points. [ABSTRACT FROM AUTHOR]

Pseudojuloides pluto, new species, is described on the basis of the holotype and 11 paratypes from Wake Island, northeastern Micronesia, and nine paratypes from the Maug Islands, Northern Mariana Islands. The new species has previously been confused with Pseudojuloides atavai, but molecular analysis of mitochondrial COI reveals a difference of 6.8% in sequence data between both species, in addition to differences in meristic, morphometric, and coloration details. A second new species, Pseudojuloides proserpina, is described from Fatu Hiva, Marquesan Islands on the basis of the male holotype. The two new species are closely allied to Pseudojuloides atavai, and together form a species complex that differs from other members of the genus in having males that share the following combination of characters: interspinous membrane between the anterior two to three spines of the dorsal fin with a black spot; head extensively reticulate (reduced in P. pluto, new species); dorsal-fin base with a pink stripe; abdominal region behind pectoral and pelvic fins pale lilac to orangey pink (width of this region dependent on species) with a crosshatch or honeycomb pattern; and extensive black coloration over at least posterior half of body. Additionally, females of both P. atavai and P. pluto, new species, are distinctly bicolored (versus unicolored and suffused in all other congeneric species). Although the female form of P. proserpina, new species, is not known, it is likely that it shares this general coloration pattern, which may serve as an additional character uniting members of the Pseudojuloides atavai complex. We briefly discuss the phylogenetic relationships of Pseudojuloides inferred on the basis of mitochondrial DNA. [ABSTRACT FROM AUTHOR]

The US Affiliated Pacific Islands have an urgent need for family caregiver education to prevent caregiver burnout and strengthen the existing culture where seniors are cared for at home by their families. The Pacific Islands Geriatric Education Center conducted a 32-hour family caregiver train-the-trainer workshop in partnership with the Yap Department of Health Services and the Yap Area Health Education Center (AHEC) from October 16 - 20, 2017. Twenty-seven participants including community health workers, peer educators, health assistants, nurses, and physicians were trained as instructors. Confidence in caregiving increased following the training and feedback was extremely positive. Competence in geriatric syndromes was improved after attending the workshop (P < .001). Lessons from the field revealed an immense value of adding home visits to the training practicum as well as the need to translate caregiving handouts into the outer island languages. Yap AHEC is committed to offering this course as part of caregiver education at the hospital and in the community. [ABSTRACT FROM AUTHOR]

Pohnpei State of the Federated States of Micronesia, located in the Northwestern Pacific Ocean, has limited health research infrastructure; chronic noncommunicable diseases (NCD) such as diabetes, heart disease, and cancer are a concern. Over 73% of Pohnpei's population is overweight or obese. E- and m- (mobile) health interventions are becoming more popular in low and middle income countries. A Rapid Assessment Procedure was conducted for formative research to identify the enabling factors and challenges related to health communication and technology in Pohnpei to address NCD prevention. Thirty-seven local stakeholders were identified through snowball sampling for interviews and group discussions about e-health readiness and NCD priorities, held in local settings. Interviews were audio recorded, with field notes taken. Data were iteratively coded using DEDOOSE. Diabetes emerged as the most serious NCD issue because both the health system and local community are having to deal with the complications and consequences. Stakeholders recommended that prevention should be integrated with diabetes treatment. Local health workers' teaching evidence-based diabetes prevention and other health promotion education were through handheld (mobile devices) was identified. The ability to readily access evidence-based health education materials and modules is compatible with community approaches providing tailored, individual and small group education and social support. This approach may serve as a key component of local NCD prevention communications initiatives integral to prevent diabetes and its complications as remote Small Island Nations face burgeoning NCD epidemics and dramatic shifts in diet and activity.

Both oral disease and middle ear infections are highly prevalent in Pacific Island children. These diseases are multifactorial and likely attributable in part to both social and environmental factors. It has been two decades since these diseases were defined in Palau, and at the time were noted to be among the most common conditions and presented a substantial burden among Palau's children. In 2006, the Ministry of Health in Palau began conducting comprehensive school health screenings in grades 1-11. While primarily used as a referral tool, this survey can also be used in epidemiologic studies to describe health trends. The current study utilized this screening data from the 2011-12 school year to characterize the prevalence of dental caries and otitis media and explore a previously suggested relationship between the two conditions, including common risk factors. It was found that over one-quarter (28.9%) of Palauan students had abnormal tympanometry results, with up to 17% indicating active otitis media. In addition, 85% of students had at least one decayed or filled tooth, with an average of 3.9 decayed or filled teeth in 12-year-olds. Both conditions were found to be more prevalent in public than in private schools; however, the two disorders were not significantly associated with each other. These findings place the prevalence of decayed, missing, and filled teeth, and otitis media in Palauan schoolchildren among the highest reported in the world. The widely recognized consequences of poor oral health and hearing impairment on learning, nutrition, and chronic disease make urgent the need for early intervention. [ABSTRACT FROM AUTHOR]

Pacific Islanders suffer from chronic diseases attributed largely to an over-consumption of processed foods. As a response, the CDC-funded Racial and Ethnic Approaches to Community Health (REACH) Go Local Project in Yap, Federated States of Micronesia (population: 12,000) sought to create a food intervention that would not only increase access to fresh, local foods, but benefit food vendors as well for a sustainable effect. For this program, a number of markets were chosen for selling any fresh local produce, meat, and catch. These markets agreed to allow purchasers of healthy local food of a minimum amount to be entered into a monthly raffle. Monthly winners received fresh food gift certificates while participating markets received a gift upon certificate redemption. REACH and partners distributed healthy island recipes and nutrition information at these partner markets. Formative evaluation examined customer and vendor satisfaction through interviews and surveys, and tracking of healthy food purchases and customer demographics were garnered via raffle information. Brief interviews with customers and vendors revealed favorable reactions to the Go Local Project. People enjoyed winning and vendors found satisfaction in promoting health through their businesses.

Almost a quarter of Pohnpei's population is overweight or obese, a major factor influencing a 2010 non-communicable diseases (NCD) emergency declaration. The Racial and Ethnic Approaches to Community Health (REACH) project in Pohnpei is implementing a culturally tailored policy, systems, and environmental (PSE) intervention to reduce NCDs through healthy nutrition projects. Through collaboration with traditional leaders and using traditional protocols, REACH succeeded in soliciting formal approval from a Traditional Monarch to serve only healthy beverages during events at all traditional houses in the municipality. The Governor, in turn, also supported this initiative. This project cultivated relationships with traditional and government leaders to implement a culturally appropriate healthy nutrition PSE change intervention. [ABSTRACT FROM AUTHOR]

Sustainability is a challenge for many small islands, and particularly small island developing states, where resources are limited but challenges abundant. One such challenge is that of the abandoned motor vehicles throughout the islands of the Federated States of Micronesia, in the north Pacific. Pohnpei, the main island of Pohnpei State, has over one thousand junk vehicles decaying by its roadsides, but what are the economic conditions that have led to their presence, what are the environmental issues that these vehicles now present, and what are the barriers to dealing with them? By considering these issues, the abandoned vehicles of Pohnpei provide a unique lens through which to explore small island sustainability. [ABSTRACT FROM AUTHOR]

El Niño Southern Oscillation (ENSO) events modulate oceanographic processes that control temperature and productivity in tropical waters, yet potential interactions with low frequency climate variability, such as the Pacific Decadal Oscillation (PDO), are poorly understood. We show that ENSO and PDO together predicted (i) maximum sea-surface temperatures (SST), which were associated with coral bleaching and declines in coral cover, and (ii) maximum chlorophyll-a concentrations, which were associated with high densities of coral-predatory Acanthaster starfish, across the tropical north Pacific Ocean since 1980. Asynchrony between the positive PDO and negative ENSO (i.e., La Niña) was associated with peaks in annual SST. By contrast, synchrony between the positive PDO and positive ENSO (i.e., El Niño) was associated with peaks in chlorophyll-a. Both conditions led to ecological disturbances and significant loss of coral cover, however, spatial models revealed where impacts to reefs were expected under varying climate scenarios. The 2015/17 ENSO event was coupled with a positive PDO and resulted in high SST and Acanthaster abundances in eastern Micronesia, while positive coral growth occurred in western Micronesia. Our novel approach for forecasting coral growth into the future may be applicable to other oceanic regions with differing oceanographic modulators. [ABSTRACT FROM AUTHOR]

The genus Acephalonomia Strejček, 1990 is revalidated and its single species, Acephalonomia cisidophaga Strejček, 1990, from Czech Republic and Slovakia is restituted in the original combination. The revalidation is based on distinct characters: antennae with eight flagellomeres and prestigmal abscissa of R1 vein dilated. The intraspecific polymorphism is also relevant for revalidation, although not exclusively so. We redescribe and illustrate the type species Acephalonomia cisidophaga and describe and illustrate a second new species with eight antennal flagellomeres from the Mariana Islands, Acephalonomia micronesica sp. n., and provide a key to this genus.

Background: The current study investigated the prevalence of depressed mood, suicide ideation, suicide plan, and suicide attempt and their associations with health risk behaviors among high school adolescents in the Commonwealth of the Northern Mariana Islands (CNMI).Methods: This is a cross-sectional study analyzing self-reported data from the 2017 CNMI Youth Risk Behavior Survey (n = 1943). Modified Poisson regression models were used to identify the associations between 17 health risk behavior variables, including violence-related behaviors, substance use behaviors, sexual behaviors, and early risk-taking behaviors, and four variables related to depressed mood and suicidal behaviors.Results: 40.7% adolescents reported being depressed, 25.0% reported suicide ideation, 22.8% reported formulating a suicide plan, and 13.6% attempted suicide. Female adolescents were more likely to report depressed mood and all included suicidal behaviors (p < 0.001). Being in a physical fight and forced sexual intercourse were associated with depressed mood, suicide ideation, suicide plan, and suicide attempt for both female and male adolescents. Use of "soft drugs" such as current smoking was associated with depressed mood (ARR = 2.33, 95% CI = 1.56-3.45, p < 0.001), suicide ideation (ARR = 1.23, 95% CI = 1.08-1.43, p < 0.001), suicide plan (ARR = 1.19; 95% CI = 1.05-1.35; p < 0.001), and suicide attempt (ARR = 1.18; 95% CI = 1.06-1.30; p < 0.001) for females, whereas use of "hard drugs" such as heroin was associated with depressed mood (ARR = 2.27, 95% CI = 1.37-3.85, p < 0.01), suicide ideation (ARR = 1.30, 95% CI = 1.01-1.67, p < 0.05), suicide plan (ARR = 1.82; 95% CI = 1.22-2.70; p < 0.01), and suicide attempt (ARR = 2.78; 95% CI = 1.47-5.26; p < 0.01) for male adolescents.Conclusion: The prevalence of depressed mood, suicide ideation, suicide plan, and suicide attempt among CNMI adolescents was high, especially in female adolescents. While there were gender differences, many of the health risk behaviors were associated with depressed mood and suicidal behaviors. As sociodemographic factors are difficult to change, modifiable factors should be targeted to improve the mental health of adolescents. [ABSTRACT FROM AUTHOR]

Fifteen species of reptiles are recorded from among the nine northernmost atolls in the Republic of the Marshall Islands (RMI): 3 sea turtles, 10 lizards (3 geckos, 6 skinks, 1 monitor lizard) and 1 typhlopid snake. None is endemic to the Marshalls and all are widely distributed in Micronesia and, in many cases, well beyond. The Common House Gecko, Hemidactylus frenatus, Mariana Monitor, Varanus tsukamotoi, and Brahminy Blindsnake, Indotyphlops braminus, probably were introduced in recent times, but to what extent the other species arrived by natural dispersal, or, alternatively, by human-assisted transport at various times since the initial settlement of the islands about 2,000 years ago, is unknown. The 126 specimens of lizards collected from among eight of the atolls during March/April 2019 include the first records of terrestrial reptiles from Ailinginae Atoll, and the first records of Hemidactylus frenatus from Rongelap, Bokak, and Utirik Atolls, Gehyra oceanica from Rongelap and Taka Atolls, and Lepidodactylus lugubris from Utirik Atoll. Numerous other distribution records obtained from online databases—with the vast majority previously unreported in the literature—are included along with the earliest collection date in the RMI of H. frenatus and a revised early collection date for I. braminus.

The spectrum of dermatoses in the pediatric population of the Republic of Palau is unknown and largely unmentioned in publication. All Palauan pediatric patients who consulted the Shin Kong Medical Assistant Program to Palau dermatology services at Belau National Hospital (BNH) and local dispensaries from 2015 to 2018 were analyzed. The results were classified according to age and sex and also analyzed by region. This population included a total of 155 patients, with 92 girls and 63 boys. Eczema (52.9%), superficial fungal infection (21.93%), and bacterial infection (16.77%) were the most frequent conditions. More than 20% of the patients presented with more than one concurrent skin disease. Among the disease spectrum, the frequency of atopic dermatitis was comparable: 29.1% in girls and 28.6% in boys. Superficial fungal infections were more common in boys, with a frequency of 31.7% as opposed to 15.2% in girls. The results were also analyzed according to region: 123 patients were seen at BNH and 32 patients were seen at the local dispensaries. Bacterial infection was more common at the local dispensaries (37.5%) than at BNH (11.4%). Hereby, we describe the pattern of skin diseases in Palauan children. [ABSTRACT FROM AUTHOR]

Areca nut use is a cause of higher rates of oral cavity cancer in the Commonwealth of the Northern Mariana Islands (CNMI). Little is known about patient insights into the risks of areca nut use worldwide. The purpose of this study is to evaluate perceptions of areca nut use and oral cancer among chewers in the CNMI. This is a survey study undertaken at the CNMI's only regional health center--300 adult participants completed a 21-question survey that assessed demographics, chewing behaviors, perceptions of areca nut use and oral cancer, and the willingness to participate in cessation and screening programs. Data was analyzed using chi-squared tests, at a significance value of P < .05. The participant average age was 38, and 41% were male. Almost all (92%) knew that chewing areca nut causes oral cancer, but only 13% correctly identified the actual areca nut as a carcinogen. About half (59%) believed that oral cancer could be treated. Most people (74%) were willing to participate in screening programs for oral cancer. Those who chewed areca nut daily were more likely to be interested in medicated replacement products relative to those who chewed less frequently (P = .048). In conclusion, there are drastic misperceptions about areca nut and oral cancer in the CNMI. Efforts should be made towards promoting awareness of the carcinogenicity of the actual areca nut, and the treatability of oral cancer. Mandated educational warnings should be required with areca nut sales. Further research evaluating substitution methods and screening programs is indicated. [ABSTRACT FROM AUTHOR]

To explore the frequency and severity of temporomandibular joint osteoarthritis (TMJ-OA) and its causative factors in a skeletal assemblage from the prehistoric site of Chelechol ra Orrak, Palau, western Micronesia. 50 temporomandibular joint surfaces (mandibular condyles and articular eminences), representing a minimum of 22 adult individuals, 17 of which retain teeth. Joint surfaces were macroscopically evaluated for characteristics associated with TMJ-OA and joint morphology. Dental remains were scored for tooth wear and staining. Nine individuals (40.1 %) displayed lesions typical of TMJ-OA. The strongest associations were between tooth wear and TMJ-OA. Indirect effects of parafunctional dental activity appear to be a factor in TMJ-OA frequency at Chelechol ra Orrak. While betel nut chewing may be one of those activities, it does not appear to be solely driving the presence of TMJ-OA. This study highlights the association between a specific parafunctional use of the temporomandibular joint and the potential pathological consequences. It also reinforces the need to carefully evaluate the archaeological context of skeletal remains in order to evaluate specific etiological factors in the presence of TMJ-OA in present and past populations. Sample sizes are limited in this study. This will increase as excavations continue. Because dental occlusion appears to be associated with TMJ-OA, focus on dental conditions affecting occlusal patterns, such as third molar agenesis, antemortem tooth loss, and malocclusion, and their relationship to TMJ-OA frequency, are recommended.

Hadreule Thomson, 1859 is a small genus of ciid beetles, comprising three Holarctic and one Australasian species. Here, three additional species from the Southern Hemisphere are described: H. mineira sp. nov. from Southeast and Northeast Brazil, characterised by the eight‐segmented antennae and male with large abdominal sex patch; H. vivianae sp. nov. from Southeast Brazil, characterised by the elytra darker than pronotum and male with small abdominal sex patch; and H. pacifica sp. nov. from Polynesian and Micronesian islands, characterised by the third antennomere being twice as long as the fourth and the possession of a two‐segmented antennal club. A brief description and images of the presumed larva of H. pacifica sp. nov. are also provided, together with images of the presumed larva of H. mineira sp. nov. and an identification key for adults of the world species of Hadreule.

Aim: Islands provide opportunities for isolation and speciation. Many landmasses in the Indo‐Australian Archipelago (IAA) are oceanic islands, and founder‐event speciation is expected to be the predominant form of speciation of volant taxa on these islands. We studied the biogeographic history of flying foxes, a group with many endemic species and a predilection for islands, to test this hypothesis and infer the biogeographic origin of the group. Location: Australasia, Indo‐Australian Archipelago, Madagascar, Pacific Islands. Taxon: Pteropus (Pteropodidae). Methods: To infer the biogeographic history of Pteropus, we sequenced up to 6,169 bp of genetic data from 10 markers and reconstructed a multilocus species tree of 34 currently recognized Pteropus species and subspecies with three Acerodon outgroups using BEAST and subsequently estimated ancestral areas using models implemented in BioGeoBEARS. Results: Species‐level resolution was occasionally low because of slow rates of molecular evolution and/or recent divergences. Older divergences, however, were more strongly supported and allow the evolutionary history of the group to be inferred. The genus diverged in Wallacea from its common ancestor with Acerodon; founder‐event speciation out of Wallacea was a common inference. Pteropus species in Micronesia and the western Indian Ocean were also inferred to result from founder‐event speciation. Main conclusions: Dispersal between regions of the IAA and the islands found therein fostered diversification of Pteropus throughout the IAA and beyond. Dispersal in Pteropus is far higher than in most other volant taxa studied to date, highlighting the importance of inter‐island movement in the biogeographic history of this large clade of large bats.

Scientific evidence demonstrated a causal relationship between Zika virus infection during pregnancy and neurologic abnormalities and other congenital defects. The U.S. government's Zika Virus Disease Contingency Response Plan recognized the importance of preventing unintended pregnancy through access to high-quality family planning services as a primary strategy to reduce adverse Zika-related birth outcomes during the 2016–2017 Zika virus outbreak. The U.S.-affiliated Pacific Islands (USAPI) includes three U.S. territories: American Samoa, the Commonwealth of the Northern Mariana Islands, and Guam, and three independent countries in free association with the United States: the Federated States of Micronesia, the Republic of the Marshall Islands, and the Republic of Palau. Aedes spp. mosquitoes, the primary vector that transmits Zika virus, are common across the Pacific Islands, and in 2016, laboratory-confirmed cases of Zika virus infection in USAPI were reported. CDC conducted a rapid assessment by reviewing available reproductive health data and discussing access to contraception with family planning providers and program staff in all six USAPI jurisdictions between January and May 2017. In this report, we summarize findings from the assessment; discuss strategies developed by jurisdictions to respond to identified needs; and describe a training that was convened to provide technical assistance to USAPI. Similar rapid assessments may be used to identify training and technical assistance needs in other emergency preparedness and response efforts that pose a risk to pregnant women and their infants.

Phellinus noxius is a root-decay pathogen with a pan-tropical/subtropical distribution that attacks a wide range of tree hosts. For this study, genomic sequencing was conducted on P. noxius isolate P919-02W.7 from Federated States of Micronesia (Pohnpei), and its gene expression profile was analyzed using different host wood (Acer , Pinus , Prunus , and Salix) substrates. The assembled genome was 33.92 Mbp with 2954 contigs and 9389 predicted genes. Only small differences were observed in size and gene content in comparison with two other P. noxius genome assemblies (isolates OVT-YTM/97 from Hong Kong, China and FFPRI411160 from Japan, respectively). Genome analysis of P. noxius isolate P919-02W.7 revealed 488 genes encoding proteins related to carbohydrate and lignin metabolism, many of these enzymes are associated with degradation of plant cell wall components. Most of the transcripts expressed by P. noxius isolate P919-02W.7 were similar regardless of wood substrates. This study highlights the vast suite of decomposing enzymes produced by P. noxius , which suggests potential for degrading diverse wood substrates, even from temperate host trees. This information contributes to our understanding of pathogen ecology, mechanisms of wood decomposition, and pathogenic/saprophytic lifestyle. [ABSTRACT FROM AUTHOR]

Centuries ago in western Micronesia, Yapese islanders sailed to the Palauan archipelago 250 miles away to carve their famous stone money disks (rai) from limestone and then transported them back for use as exchange valuables in various social transactions. While rai were not strictly currency, their value is similar to other traditional and modern objects where worth is arbitrarily based on both real and perceived attributes. Recently, corollaries have been made between rai and newly established electronic cryptocurrencies that use blockchain technology—essentially, digital ledgers that track financial transactions in real time across a computer network to ensure that they are seamless and incorruptible. In this study, we examine the sociophysical similarities and differences between stone money and cryptocurrencies that rely on blockchain, both of which demand a unified and continuous chain of information to ensure that the value is known and ownership indisputable. This research suggests that stone money: (a) is an exemplary ancient analog to blockchain that used oral ledgers solidified through social networks to create accurate and unbroken lines of communication so that economic relationships involving rai could be established, maintained, exchanged, and rectified, and (b) may have been a progenitor that inspired the development of Bitcoin.
