Perception of Type 2 Diabetes Mellitus (T2DM) patients on diabetes self-care management in Fiji.

INTRODUCTION: The prevalence of diabetes has increased globally where Type 2 Diabetes Mellitus (T2DM) is more common than any other type of diabetes. Self- care management education of diabetes provides skills and information for diabetic patients to effectively perform their own self diabetic self-care for optimum glycemic index control. As T2DM is a growing health issue in Fiji, promoting diabetes self manages among patients is a need, however there is lack of evidence in this regard. Therefore, the aim of this study is to explore the perception of T2DM patients on diabetic self-care management. METHOD: This study used a qualitative method among T2DM patients regarding diabetic self-care management in Central Division, Fiji in 2022. This study was conducted in SOPD (Special Out Patient Department) clinics in the three chosen governmental health centers in the central division of Fiji. The study sample inclusion criteria were only T2DM patients, and no other types of diabetes, patients who are 18years and above, patients who are attending clinic at least for more than 6 months, self-identified as Fijian participants of any ethnicity or gender. The study settings were also purposively selected but the study sample was selected using purposive sampling. In depth interview using semi-structured open-ended questionnaires was used to collect data. Thematic analysis was done, followed by reviewing themes, defining and naming them. RESULTS: Thirty patients participated in this study. Five major themes emerged from the in-depth interview including; patient factors that affect diabetes self-care management, behavior and attitude towards T2DM self-care management, health services delivery, challenges and barriers faced by patients to perform diabetes self-care management, and recommendations to improve patient self-care management. Patients in this study have good knowledge about T2DM and the self-care management they have to perform. It is the patients' attitude and behavior towards T2DM self-care management that affects patients to perform self-care management. The study also showed patients have gained good knowledge from Health Care Workers (HCW). Socio-economic and psychological status also played a vital part in patients' self-care management. Apart from challenges, there were opportunities to learn the difficulties patients face in order to perform self-care management. CONCLUSION: The results of this study revealed a combination of individual, cultural, and health systematic related factors as the mots influencer of diabetes self-management among patients in Fiji. Patients have to take ownership of their own health in order to improve their blood sugar reading and reduce complication of diabetes. Tailored interventions that consider patients' belief and address potential challenges would be useful. A lot is needed in terms of upgrading facilities for the comfort of patients and need to collaborate more with other multidisciplinary team and stakeholders.

Energy, nutrient and overall healthiness of processed packaged foods in Fiji, a comparison between 2018 and 2020.

In Fiji, packaged foods are becoming increasingly available. However, it is unknown if nutrition composition of these foods has changed. This study aims to assess changes in energy, nutrient content and healthiness of packaged foods by comparing data from five major supermarkets in Fiji in 2018 and 2020. Foods were categorised into 14 groups; nutrient composition information was extracted and healthiness assessed using Health Star Rating (HSR). Descriptive statistics and a separate matched products analysis was conducted summarising differences in nutrient content and HSR. There was limited evidence of change in the nutrient content of included products however, there was a small reduction in mean saturated fat in the snack food category (-1.0 g/100 g, 95% CI -1.6 to -0.4 g/100 g). The proportion of products considered healthy based on HSR, increased in the convenience foods category (28.4%, 95% CI 8.3 to 48.5) and decreased in non-alcoholic beverages (-35.2%, 95% CI -43.6 to -26.9). The mean HSR score increased in the fruit and vegetables category (0.1 (95% CI 0.1, 0.2)) and decreased for non-alcoholic beverages (-1.1 (-1.3, -0.9)) and the sauces, dressings, spreads, and dips category (-0.3 (-0.3, -0.2)). Strengthened monitoring of the food supply is needed to improve the healthiness of foods available.

Life histories in Fiji as reconstructed from first millennium CE Sigatoka Sand Dune burials using isotopes.

This paper aims to re-examine the dietary practices of individuals buried at Sigatoka Sand Dunes site (Fiji) in Burial Ground 1 excavated by Simon Best in 1987 and 1988 using two approaches and a reassessment of their archaeological, bioarchaeological and chronological frame. First, stable carbon and nitrogen isotope analysis was applied to document dietary changes between childhood and adulthood using an intra-individual approach on paired bone-tooth. Second, the potential adaptation of the individuals to their environment was evaluated through regional and temporal comparisons using inter-individual bone analysis. Ten AMS radiocarbon dates were measured directly on human bone collagen samples, placing the series in a range of approximately 600 years covering the middle of the first millennium CE (1,888 to 1,272 cal BP). δ13C and δ15N ratios were measured on bone and tooth collagen samples from 38 adult individuals. The results show that δ15N values from tooth are higher than those s from bone while bone and tooth δ13C values are similar, except for females. Fifteen individuals were included in an intra-individual analysis based on paired bone and tooth samples, which revealed six dietary patterns distinguished by a differential dietary intake of marine resources and resources at different trophic levels. These highlight sex-specific differences not related to mortuary practices but to daily life activities, supporting the hypothesis of a sexual division of labour. Compared to other Southwest Pacific series, Sigatoka diets show a specific trend towards marine food consumption that supports the hypothesis of a relative food self-sufficiency requiring no interactions with other groups.

Extreme mortality during a historical measles outbreak on Rotuma is consistent with measles immunosuppression.

Until the early twentieth century, populations on many Pacific Islands had never experienced measles. As travel to the Pacific Islands by Europeans became more common, the arrival of measles and other pathogens had devastating consequences. In 1911, Rotuma in Fiji was hit by a measles epidemic, which killed 13% of the island population. Detailed records show two mortality peaks, with individuals reported as dying solely from measles in the first and from measles and diarrhoea in the second. Measles is known to disrupt immune system function. Here, we investigate whether the pattern of mortality on Rotuma in 1911 was a consequence of the immunosuppressive effects of measles. We use a compartmental model to simulate measles infection and immunosuppression. Whilst immunosuppressed, we assume that individuals are vulnerable to dysfunctional reactions triggered by either (i) a newly introduced infectious agent arriving at the same time as measles or (ii) microbes already present in the population in a pre-existing equilibrium state. We show that both forms of the immunosuppression model provide a plausible fit to the data and that the inclusion of immunosuppression in the model leads to more realistic estimates of measles epidemiological parameters than when immunosuppression is not included.

Strengthening rural community water safety planning in Pacific Island countries: evidence and lessons from Solomon Islands, Vanuatu, and Fiji.

Pacific Island Countries (PICs) collectively have the lowest rates of access to safely managed or basic drinking water and sanitation globally. They are also the least urbanised, have dynamic socioeconomic and increasing climate-linked challenges. Community-based water managers need to respond to variability in water availability and quality caused by a range of hazards. Water Safety Planning (WSP), a widely adopted approach to assessing water supply, offers a risk-based approach to mitigating both existing and future hazards. WSP is adaptable, and making modifications to prescribed WSP to adapt it to the local context is common practice. Within the Pacific Community Water Management Plus research project, we used formative research and co-development processes to understand existing local modifications, whether further modifications are required, and, to develop additional modifications to WSP in Fiji, Vanuatu and Solomon Islands. The types of additional local modifications we recommend reflect the unique context of PICs, including adjusting for community management of water supplies and required collective action, community governance systems, levels of social cohesion in communities, and preferred adult-learning pedagogies. Incorporating modifications that address these factors into future WSP will improve the likelihood of sustained and safe community water services in Pacific and similar contexts.

Successful introgression of wMel Wolbachia into Aedes aegypti populations in Fiji, Vanuatu and Kiribati.

Pacific Island countries have experienced periodic dengue, chikungunya and Zika outbreaks for decades. The prevention and control of these mosquito-borne diseases rely heavily on control of Aedes aegypti mosquitoes, which in most settings are the primary vector. Introgression of the intracellular bacterium Wolbachia pipientis (wMel strain) into Ae. aegypti populations reduces their vector competence and consequently lowers dengue incidence in the human population. Here we describe successful area-wide deployments of wMel-infected Ae. aegypti in Suva, Lautoka, Nadi (Fiji), Port Vila (Vanuatu) and South Tarawa (Kiribati). With community support, weekly releases of wMel-infected Ae. aegypti mosquitoes for between 2 to 5 months resulted in wMel introgression in nearly all locations. Long term monitoring confirmed a high, self-sustaining prevalence of wMel infecting mosquitoes in almost all deployment areas. Measurement of public health outcomes were disrupted by the Covid19 pandemic but are expected to emerge in the coming years.

Redesigning Prehospital Care: Fiji's Response to the COVID-19 Pandemic.

The benefits of emergency care systems in low- and middle-income countries are well-described. Passed in the wake of the coronavirus disease 2019 (COVID-19) pandemic, the World Health Assembly (WHA) Resolution 76.2 emphasizes the importance of communication, transportation and referral mechanisms, and the linkages between communities, primary care, and hospital care. Literature describing prehospital care and ambulance system development is scarce, with little data on the effectiveness and cost effectiveness of different options. Prehospital care systems in Pacific Island countries are under-developed. In Fiji, out-of-hospital care is fragmented with an uncoordinated patchwork of ambulance providers. There is no scope of practice or training requirement for providers and no patient care records. There are no data relating to demand, access, and utilization of ambulance services.In response to a surge of COVID-19 cases in 2021, the Fiji government created a Prehospital Emergency Care Coordination Center (PHECCC) in the capital Suva, which was operational from July-October 2021. Access was via a toll-free number, whereby the public could receive a medical consultation followed by phone advice or dispatch of an ambulance for a home assessment, followed by transportation to hospital, if required. The PHECCC also provided coordination of inter-facility transport and retrieval of the critically ill.The system that was created met many of the prehospital care standards set by emergency care leaders in the region and created the first dataset relating to ambulance demand and utilization. This is the first article to document prehospital system development in the Pacific region.

Unique microbial diversity, community composition, and networks among Pacific Islander endocervical and vaginal microbiomes with and without Chlamydia trachomatis infection in Fiji.

IMPORTANCE: Chlamydia trachomatis (Ct) is the most common sexually transmitted bacterium globally. Endocervical and vaginal microbiome interactions are rarely examined within the context of Ct or among vulnerable populations. We evaluated 258 vaginal and 92 paired endocervical samples from Fijian women using metagenomic shotgun sequencing. Over 37% of the microbiomes could not be classified into sub-community state types (subCSTs). We, therefore, developed subCSTs IV-D0, IV-D1, IV-D2, and IV-E-dominated primarily by Gardnerella vaginalis-to improve classification. Among paired microbiomes, the endocervix had a significantly higher alpha diversity and, independently, higher diversity for high-risk human papilloma virus (HPV) genotypes compared to low-risk and no HPV. Ct-infected endocervical networks had smaller clusters without interactions with potentially beneficial Lactobacillus spp. Overall, these data suggest that G. vaginalis may generate polymicrobial biofilms that predispose to and/or promote Ct and possibly HPV persistence and pathogenicity. Our findings expand on the existing repertoire of endocervical and vaginal microbiomes and fill in knowledge gaps regarding Pacific Islanders.

Diabetes Cam: An Objective Methodology to Study Diabetes Self-Management.

INTRODUCTION: The prevalence of Type 2 Diabetes Mellitus (T2DM) is rapidly increasing throughout the world. T2DM is primarily a self-managed disease yet clinical studies indicate that a large proportion of adults with T2DM struggle to self-manage their diabetes. This puts them at high risk of developing diabetes-related complications. This study presents Diabetes Cam, a new methodology to objectively study T2DM self-management and identify its barriers and facilitators. METHODS: Thirty adults with diabetes of i-taukei descent from the 4 medical divisions throughout Fiji wore a camera for 4 days that automatically recorded images every 7 seconds. They also participated in in-depth photo-elicitation interviews to explore their experiences and perceptions of T2DM self-management. Data was collected between October 2021 and May 2022, and the analysis was done in August 2023. RESULTS: Approximately 11,500 images per participant were generated providing rich data. The method is ethical, legal, and acceptable for adults with T2DM, their families, and the wider community. The images can be readily coded for food availability and consumption, physical activity, transportation, medication use, and foot care. Photo-elicitation enabled further information on what was occurring within the images and about participants' perspectives on diabetes self-management. CONCLUSIONS: The Diabetes Cam methodology enabled automated, objective observation of participants' T2DM self-management and their perspectives on self-management. It provides unique insights into diabetes self-management and ways to improve diabetes self-management. It provides valuable data to develop strategies to enhance diabetes self-management for people living with diabetes, their families, the wider community, health professionals, and policymakers.

Food insecurity, COVID-19 and diets in Fiji - a cross-sectional survey of over 500 adults.

INTRODUCTION: Food insecurity is associated with inadequate nutrition and increased rates of chronic disease. The primary aim of this study was to assess self-reported food insecurity and the perceived impact of COVID-19 on food security, in two regional districts of Central Fiji, as part of a broader program of work on strengthening and monitoring food policy interventions. The secondary aim was to explore the relationship between food insecurity and salt, sugar and fruit and vegetable intake. METHODS: Seven hundred adults were randomly sampled from the Deuba and Waidamudamu districts of Viti Levu, Fiji. Interview administered surveys were conducted by trained research assistants with data collected electronically. Information was collected on demographics and health status, food security, the perceived impact of COVID-19 on food security, and dietary intake. Food insecurity was assessed using nine questions adapted from Fiji's 2014/5 national nutrition survey, measuring markers of food insecurity over the last 12 months. Additional questions were added to assess the perceived effect of COVID-19 on responses. To address the secondary aim, interview administered 24-hour diet recalls were conducted using Intake24 (a computerised dietary recall system) allowing the calculation of salt, sugar and fruit and vegetable intakes for each person. Weighted linear regression models were used to determine the relationship between food insecurity and salt, sugar and fruit and vegetable intake. RESULTS: 534 people participated in the survey (response rate 76%, 50.4% female, mean age 42 years). 75% (75.3%, 95% CI, 71.4 to 78.8%) of people reported experiencing food insecurity in the 12 months prior to the survey. Around one fifth of people reported running out of foods (16.8%, 13.9 to 20.2%), having to skip meals (19.3%, 16.2 to 22.9%), limiting variety of foods (19.0%, 15.9 to 22.5%), or feeling stressed due to lack of ability to meet food needs (19.5%, 16.4 to 23.0%). 67% (66.9%, 62.9 to 70.7%) reported becoming more food insecure and changing what they ate due to COVID-19. However, people also reported positive changes such as making a home garden (67.8%, 63.7 to 71.6%), growing fruit and vegetables (59.5%, 55.6 to 63.8%), or trying to eat healthier (14.7%, 12.0 to 18.0%). There were no significant associations between food insecurity and intakes of salt, sugar or fruit and vegetables. CONCLUSION: Participants reported high levels of food insecurity, exceeding recommendations for salt and sugar intake and not meeting fruit and vegetable recommendations, and becoming more food insecure due to COVID-19. Most participants reported making home gardens and/or growing fruit and vegetables in response to the pandemic. There is an opportunity for these activities to be fostered in addressing food insecurity in Fiji, with likely relevance to the Pacific region and other Small Island Developing States who face similar food insecurity challenges.

Changing climates, compounding challenges: a participatory study on how disasters affect the sexual and reproductive health and rights of young people in Fiji.

Pacific youth are at the forefront of the climate crisis, which has important implications for their health and rights. Youth in Fiji currently bear a disproportionate burden of poor experiences and outcomes related to their sexual and reproductive health and rights (SRHR). There is limited information about how the increasing climate impacts may affect their SRHR, and what the implications may be for climate action and disaster risk reduction. We aimed to explore the experiences of 21 Fijian youth in fulfilling their SRHR when living through multiple natural hazards. We conducted 2 workshops and 18 individual semistructured interviews using visual and storytelling methods. Irrespective of the type of hazard or context of disasters, participants identified limited agency as the main challenge that increased SRHR risks. Through reflexive thematic analysis, we identified four themes centred around 'youth SRHR agency'; (1) information and knowledge, (2) community and belonging, (3) needs and resources, and (4) collective risks. These themes encompassed multiple factors that limited youth agency and increased their SRHR risks. Participants highlighted how existing challenges to their SRHR, such as access to SRHR information being controlled by community gatekeepers, and discrimination of sexual and gender diverse youth, were exacerbated in disasters. In disaster contexts, immediate priorities such as water, food and financial insecurity increased risks of transactional early marriage and transactional sex to access these resources. Daily SRHR risks related to normalisation of sexual and gender-based violence and taboos limited youth agency and influenced their perceptions of disasters and SRHR risks. Findings offer important insights into factors that limited youth SRHR agency before, during and after disasters. We underscore the urgency for addressing existing social and health inequities in climate and disaster governance. We highlight four key implications for reducing youth SRHR risks through whole-of-society approaches at multiple (sociocultural, institutional, governance) levels.

Protecting children from unhealthy food marketing: a comparative policy analysis in Australia, Fiji and Thailand.

Restrictions on marketing of unhealthy foods and beverages to children is a globally recommended policy measure to improve diets and health. The aim of the analysis was to identify opportunities to enable policy learning and shift beliefs of relevant actors, to engender policy progress on restrictions on marketing of unhealthy foods to children. We drew on the Advocacy Coalition Framework to thematically analyse data from qualitative policy interviews conducted Australia (n = 24), Fiji (n = 10) and Thailand (n = 20). In all three countries two clear and opposing advocacy coalitions were evident within the policy subsystem related to regulation of unhealthy food marketing, which we termed the 'strengthen regulation' and 'minimal/self regulation' coalitions. Contributors to policy stasis on this issue were identified as tensions between public health and economic objectives of government, and limited formal and informal spaces for productive dialogue. The analysis also identified opportunities for policy learning that could enable policy progress on restrictions on marketing of unhealthy foods to children as: taking an incremental approach to policy change, defining permitted (rather than restricted) foods, investing in new public health expertise related to emerging marketing approaches and scaling up of monitoring of impacts. The insights from this study are likely to be relevant to many countries seeking to strengthen regulation of marketing to children, in response to recent global recommendations.

ComsystanJ: A collection of Fiji/ImageJ2 plugins for nonlinear and complexity analysis in 1D, 2D and 3D.

Complex systems such as the global climate, biological organisms, civilisation, technical or social networks exhibit diverse behaviours at various temporal and spatial scales, often characterized by nonlinearity, feedback loops, and emergence. These systems can be characterized by physical quantities such as entropy, information, chaoticity or fractality rather than classical quantities such as time, velocity, energy or temperature. The drawback of these complexity quantities is that their definitions are not always mathematically exact and computational algorithms provide estimates rather than exact values. Typically, evaluations can be cumbersome, necessitating specialized tools. We are therefore introducing ComsystanJ, a novel and user-friendly software suite, providing a comprehensive set of plugins for complex systems analysis, without the need for prior programming knowledge. It is platform independent, end-user friendly and extensible. ComsystanJ combines already known algorithms and newer methods for generalizable analysis of 1D signals, 2D images and 3D volume data including the generation of data sets such as signals and images for testing purposes. It is based on the framework of the open-source image processing software Fiji and ImageJ2. ComsystanJ plugins are macro recordable and are maintained as open-source software. ComsystanJ includes effective surrogate analysis in all dimensions to validate the features calculated by the different algorithms. Future enhancements of the project will include the implementation of parallel computing for image stacks and volumes and the integration of artificial intelligence methods to improve feature recognition and parameter calculation.

Perceptions on Healthy Eating Impact the Home Food Environment: A Qualitative Exploration of Perceptions of Indigenous Food Gatekeepers in Urban Fiji.

The home food environment (HFE) can have important direct and indirect impacts on dietary practices. Nutrient transitions in the HFE of Pacific Island countries (PICs) are key contributors of the high rates of adult and childhood overweight and obesity in the region. Pacifica mothers are important sociocultural agents who play critical roles in their HFE through setting eating-appropriateness standards and mitigating the impacts of food availability and accessibility on the HFE. This study used an interpretative phenomenological approach to explore how urban indigenous Fijian mothers perceive healthy eating and how these perceptions impacted the food decisions they made for their families. Mothers in this study held complex, multifaceted perceptions on healthy eating and these perceptions had both positive and negative impacts on the family food choices they made, the strategies they adopted for healthy eating and their perceived motivators for healthy eating. The findings of this study underscore the need for a deeper understanding and analysis of uptake of public health messaging related to healthy and unhealthy eating and the importance of targeted promotion of healthful nutrition in this community. Promoting consumption of traditional and locally grown foods can enhance nutrition and food security and combat nutrition transition in the region.

"I think taking herbal medicine first can help prevent. If it doesn't work, then can take start taking the medication given by the doctors." Patients' perceptions towards hypertension in Fiji.

BACKGROUND: Hypertension remains a public health challenge worldwide however, the prevention, detection, treatment and management of this condition are not highly prioritized. Health knowledge has an important impact on individual's health. The ability to actively participate in screening, diagnosis and management of hypertension are influenced by patient's knowledge of hypertension. To understand why hypertension is so difficult to control, it may be of benefit to gain an understanding of the patient's perspective. Hence, the aim of the study is to explore the perceptions of patients on prevention and diagnosis of hypertension in Fiji. METHODS: The study used a qualitative method approach. The study was conducted at the four purposively selected health centers in the Lautoka/ Yasawa medical subdivision. A purposive sampling was used which included all the patients who attended the SOPD, age more than 18 years and above, diagnosed with hypertension for 6 months or more and attended clinic at one of the 4 selected health centers. Semi-structured open-ended interview guide were used to collect data among patients through in-depth interviews. Thematic analysis was used manually to analyze the data using four steps that is immersion in the data, coding the data, creating categories and identifying themes / subthemes. RESULTS: Twenty-five SOPD patients took part in the in-depth interview and the responses were grouped into two themes. The themes emerged included hypertension knowledge and diagnosis of hypertension in a closed family and self. Subthemes derived from the hypertension knowledge were measures of awareness, hypertension aetiology, risk perception, origin of information and concept of prevention. Sub themes derived from the diagnosis of hypertension in a closed family were perception when first diagnosed, hypertension in relation and hypertension impact. Patients' knowledge on etiologies and risk factors of hypertension were generally poor. Majority of the participants learnt about hypertension in hospitals and few over radios and television. Diagnosis in a closed family triggered worrisome, fear and fright on some patients. CONCLUSION: Majority of the patients have less knowledge about various risk factors of hypertension. Worrisome, fearful, frightful, frustration and sadness were some of the reactions and emotions highlighted by the patients. It is important to design culturally tailored interventions that address the psychological and behavioral needs of the patients. Recommendation to conduct further studies to understand the perception of hypertension among the general public.

Effect of COVID-19 on dental service delivery in Fiji: Perspective of Dental Officers (Dos) and Dental Managers (DMs).

BACKGROUND: Corona Virus Disease 2019 (COVID-19) was declared a global pandemic by the World Health Organization (WHO) has had significant impact on dentistry in Fiji. Due to lack of previous study, this study aims to explore the perspective of Dental Officers (DOs) and Dental Managers (DMs) on the effects of COVID-19 on dental service delivery in Fiji Islands. METHODS: This qualitative study was conducted amongst 30 DOs and 17 DMs between 9th August to 12th September, 2021. It was conducted in the government dental clinics, private dental clinics and the School of Dentistry and Oral Health clinic (SDOH), in the Central Division, Fiji. The study settings were randomly selected. Purposive sampling method was used for the selection of participants who met the study criteria. Semi-structure open ended questionnaires were used for data collection through in-depth interviews via zoom. Manual thematic analysis of the data was conducted to derive themes and codes. RESULTS: The participants interviewed for the study included more female DOs (66.7%) and male DMs (58.8%). Seven themes emerged from data analysis: range of services delivered, appointment versus walk-in patients for aerosol generating procedures (AGPs), impact of pandemic on clinic opening hours, impact of COVID-19 on patient numbers, quality of services delivered, resources and infrastructure, perceptions about the burden of disease. CONCLUSION: COVID-19 has significantly affected dental service delivery. Mostly emergency dental services were delivered. AGPs were delivered on appointment basis. Most participants stated the quality of services had improved. Participants stated that they were not given adequate resources and the infrastructure was not up to standard to provide dental services during the pandemic. The dental disease burden had increased during the pandemic as per the participants. Future research can be conducted amongst other dental professionals in other divisions of the country.

A story of vicariance? how the geology of oceanic archipelagos influenced the evolutionary history of endemic damselflies.

South Pacific islands provide an ideal study system to explore patterns of speciation, specifically examining the role of dispersal versus vicariance. Dispersal is often the suggested mechanism of diversification in the South Pacific, specifically among remote island chains. Here, we provide a phylogeny of several related genera of Coenagrionidae (Odonata: Zygoptera) from the South Pacific, based on five molecular loci, in order to examine patterns of speciation in the region. We used the endemic damselfly genera Nesobasis, Nikoulabasis, and Vanuatubasis found across both Fiji and Vanuatu. Knowledge of the geologic history of the region was used to inform our understanding of the evolution of these genera. Both archipelagos used to be part of the Vitiaz arc which spanned from the Solomon Islands to Tonga and began to break apart 10-12 Ma. Results of our divergence-time estimations and biogeographic reconstructions support that the breakup of this arc acted as a significant vicariance event in the evolution of these taxa. Specifically, it led to the extant generic diversity seen in these damselflies. We find that within the archipelago of Vanuatu, that Espiritu Santo served as an important source for dispersal to other islands with Malekula acting as a stepping stone to Efate.

Use of the HESPER Web to Assess Perceived Needs Immediately After Multiple Disaster Events in Fiji.

OBJECTIVE: In January 2022, Fiji was hit by multiple natural disasters, including a cyclone causing flooding, an underwater volcanic eruption, and a tsunami. This study aimed to investigate perceived needs among the disaster-affected people in Fiji and to evaluate the feasibility of the Humanitarian Emergency Settings Perceived Needs Scale (HESPER Web) during the early stage after multiple natural disasters. METHODS: A cross-sectional study using a self-selected, non-representative study sample was conducted. The HESPER Web was used to collect data. RESULTS: In all, 242 people participated. The number of perceived serious needs ranged between 2 and 14 (out of a possible 26), with a mean of 6 (SD = 3). The top 3 most reported needs were access to toilets (60%), care for people in the community who are on their own (55%), and distress (51%). Volunteers reported fewer needs than the general public. CONCLUSIONS: The top 3 needs reported were related to water and sanitation and psychosocial needs. Such needs should not be underestimated in the emergency phase after natural disasters and may require more attention from responding actors. The HESPER Web was considered a usable tool for needs assessment in a sudden onset disaster.
