Oldest old's travel mode choice and new mobility technology acceptance: case in America and China.

Introduction: The oldest olds (aged 85 and over) are the fastest-growing age segment. However, our understanding of their mobility is limited. To address this gap, we invited 19 U.S. and 30 Chinese "oldest old" to take part in focus groups and complete a mobility questionnaire. We focus on travel mode choice, which includes changes in travel modes, frequency of usage, and perceptions of comfort. Methods: Older adults' familiarity and acceptance of new mobility technologies (e.g., ridesharing, carsharing, and autonomous vehicles) were measured by questionnaire and focus group. Word clouds were also used to illustrate people's reasons for choosing their primary mode of transportation. Results and discussion: The results show that both panels of older adults similarly feel some extent of travel limitations. But the responses among the two groups differ: 18 American participants chose "drive myself" as their primary option a decade ago, while 11 chose it now; no Chinese participants selected it either a decade ago or now. Both currently and 10 years ago, there was a significant difference in mode choice between participants in China and the United States. However, this gap has narrowed over the past decade. Participants in China have significantly changed their transportation preferences compared to 10 years ago, while participants in the US have remained nearly unchanged. American respondents consider "ease" as an important factor, while Chinese respondents pay more attention to "safety" and "no other option to get around" when making travel mode choices. Compared to Chinese participants, American participants were more comfortable with driving an autonomous vehicle. These differences may result from the various developmental stages and transportation policies of the two countries. This study supports the development of new mobility technologies for the oldest old to improve their quality of life.

[Regional inequalities in access to hospital birth in the state of Rio de Janeiro, Brazil: travel networks, distance, and time (2010-2019)]. / Desigualdades regionais no acesso ao parto hospitalar no Estado do Rio de Janeiro, Brasil: redes de deslocamento, distância e tempo (2010-2019).

Difficult access to birth care services is associated with infant and neonatal mortality and maternal morbidity and mortality. In this study, data from the Brazilian Unified National Health System (SUS) were used to map the evolution of geographic accessibility to hospital birth of usual risk in the state of Rio de Janeiro, Brazil, corresponding to 418,243 admissions in 2010-2011 and 2018-2019. Travel flows, distances traveled, and intermunicipal travel time between the pregnant women's municipality and hospital location were estimated. An increase from 15.9% to 21.5% was observed in the number of pregnant women who needed to travel. The distance traveled increased from 24.6 to 26km, and the travel time from 76.4 to 96.1 minutes, with high variation between Health Regions (HR). Pregnant women living in HR Central-South traveled more frequently (37.4-48.9%), and those living in the HRs Baía da Ilha Grande and Northwest traveled the largest distances (90.9-132.1km) and took more time to get to the hospital in 2018-2019 (96-137 minutes). The identification of municipalities that received pregnant women from many other municipalities and municipalities that treated a higher number of pregnant women (hubs and attraction poles, respectively) reflected the unavailability and disparities in access to services. Regional inequalities and reduced accessibility highlight the need to adapt supply to demand and review the distribution of birth care services in the state of Rio de Janeiro. This study contributes to research and planning on access to maternal and child health services and can be used as a reference study for other states in the country.

A dificuldade de acesso aos serviços de atenção ao parto está associada à mortalidade infantil e neonatal e à morbimortalidade materna. Neste estudo, dados do Sistema Único de Saúde (SUS) foram utilizados para mapear a evolução da acessibilidade geográfica ao parto hospitalar de risco habitual no Estado do Rio de Janeiro, Brasil, correspondentes a 418.243 internações nos biênios 2010-2011 e 2018-2019. Foram estimados os fluxos de deslocamento, as distâncias percorridas e o tempo de deslocamento intermunicipal entre o município de residência e de internação das gestantes. Houve um crescimento de 15,9% para 21,5% na proporção de gestantes que precisaram se deslocar. A distância percorrida aumentou de 24,6 para 26km, e o tempo de deslocamento de 76,4 para 96,1 minutos, com grande variação entre as Regiões de Saúde (RS). As gestantes residentes na RS Centro Sul se deslocaram mais frequentemente (37,4-48,9%), e as residentes nas RS Baía da Ilha Grande e Noroeste percorreram as maiores distâncias (90,9-132,1km) e levaram mais tempo para chegar ao hospital no último biênio (96-137 minutos). A identificação dos municípios que receberam gestantes de muitos outros municípios e daqueles que atenderam maior volume de gestantes (núcleos e polos de atração, respectivamente) refletiu a indisponibilidade e as disparidades no acesso aos serviços. As desigualdades regionais e a redução da acessibilidade alertam para a necessidade de adequar a oferta à demanda e de revisar a distribuição dos serviços de atenção ao parto no Rio de Janeiro. O estudo contribui para as pesquisas e o planejamento sobre o acesso a serviços de saúde materno-infantil, além de servir como referência para outros estados do país.

Exploring residential relocation- differences between newcomers and settled residents in health, travel behaviour and neighbourhood perceptions.

This study explores whether people who have recently moved to an area differ from longer-term residents in their health, travel behaviour, and perceptions of the environment. Using a large, representative sample from the UKHLS, Newcomers demonstrate significantly lower mental and physical health, reduced car commuting, and a higher likelihood of liking their neighbourhood. Area deprivation, urbanicity, household income, and age emerge as influential moderators with i.e. Newcomers in affluent areas experiencing lower physical health than Settled Residents, and rural Newcomers expressing less neighbourhood satisfaction. Our findings highlight that Newcomers' perceptions of their environment diverge and environmental influences vary among population segments, potentially impacting related health behaviours such as active travel. Furthermore, residential relocation introduces Newcomers with distinct characteristics into areas, affecting the context in which potential population health interventions aiming to influence health behaviours operate. This necessitates a deeper understanding of what influences reactions to the environment as well as ongoing adaptation of environmental interventions to respond to changing contexts within the same location over time.

Netographic narratives of user-generated travelogues on tourist destination image of Thailand.

The image of a tourist destination is considered a vital aspect of international travel experiences, yet research in this area remains limited. Adopting a combination of netography and qualitative research methodology, this study aims to contribute to the scientific knowledge of destination image development in Thailand by analysing online travelogues to evaluate how Chinese tourists interpret the idea of destination image. To achieve this goal, 146,641 words of Chinese internet comments containing the keyword "Thailand" from four major media sources and Chinese bloggers were gathered and analysed using netography methodology. The findings showed that there was a rise in public interest, in public forums, in the destination image of Thailand among Chinese outbound tourists. The study's results may provide important fundamental theoretical insights and inspire further investigation into the issue of destination image construction.

Gut microbiota composition in travellers is associated with faecal lipocalin-2, a mediator of gut inflammation.

Introduction: We examined the gut microbiota of travellers returning from tropical areas with and without traveller's diarrhoea (TD) and its association with faecal lipocalin-2 (LCN2) levels. Methods: Participants were recruited at the Hospital Clinic of Barcelona, Spain, and a single stool sample was collected from each individual to perform the diagnostic of the etiological agent causing gastrointestinal symptoms as well as to measure levels of faecal LCN2 as a biomarker of gut inflammation. We also characterised the composition of the gut microbiota by sequencing the region V3-V4 from the 16S rRNA gene, and assessed its relation with the clinical presentation of TD and LCN2 levels using a combination of conventional statistical tests and unsupervised machine learning approaches. Results: Among 61 participants, 45 had TD, with 40% having identifiable etiological agents. Surprisingly, LCN2 levels were similar across groups, suggesting gut inflammation occurs without clinical TD symptoms. Differential abundance (DA) testing highlighted a microbial profile tied to high LCN2 levels, marked by increased Proteobacteria and Escherichia-Shigella, and decreased Firmicutes, notably Oscillospiraceae. UMAP analysis confirmed this profile's association, revealing distinct clusters based on LCN2 levels. The study underscores the discriminatory power of UMAP in capturing meaningful microbial patterns related to clinical variables. No relevant differences in the gut microbiota composition were found between travellers with or without TD. Discussion: The findings suggest a correlation between gut microbiome and LCN2 levels during travel, emphasising the need for further research to discern the nature of this relationship.

Navigating geographical disparities: access to obstetric hospitals in maternity care deserts and across the United States.

BACKGROUND: Access to maternity care in the U.S. remains inequitable, impacting over two million women in maternity care "deserts." Living in these areas, exacerbated by hospital closures and workforce shortages, heightens the risks of pregnancy-related complications, particularly in rural regions. This study investigates travel distances and time to obstetric hospitals, emphasizing disparities faced by those in maternity care deserts and rural areas, while also exploring variances across races and ethnicities. METHODS: The research adopted a retrospective secondary data analysis, utilizing the American Hospital Association and Centers for Medicaid and Medicare Provider of Services Files to classify obstetric hospitals. The study population included census tract estimates of birthing individuals sourced from the U.S. Census Bureau's 2017-2021 American Community Survey. Using ArcGIS Pro Network Analyst, drive time and distance calculations to the nearest obstetric hospital were conducted. Furthermore, Hot Spot Analysis was employed to identify areas displaying significant spatial clusters of high and low travel distances. RESULTS: The mean travel distance and time to the nearest obstetric facility was 8.3 miles and 14.1 minutes. The mean travel distance for maternity care deserts and rural counties was 28.1 and 17.3 miles, respectively. While birthing people living in rural maternity care deserts had the highest average travel distance overall (33.4 miles), those living in urban maternity care deserts also experienced inequities in travel distance (25.0 miles). States with hotspots indicating significantly higher travel distances included: Montana, North Dakota, South Dakota, and Nebraska. Census tracts where the predominant race is American Indian/Alaska Native (AIAN) had the highest travel distance and time compared to those of all other predominant races/ethnicities. CONCLUSIONS: Our study revealed significant disparities in obstetric hospital access, especially affecting birthing individuals in maternity care deserts, rural counties, and communities predominantly composed of AIAN individuals, resulting in extended travel distances and times. To rectify these inequities, sustained investment in the obstetric workforce and implementation of innovative programs are imperative, specifically targeting improved access in maternity care deserts as a priority area within healthcare policy and practice.

Cross-border mobility in the Meuse-Rhine Euroregion: impact of COVID-19 border restrictions on everyday activities and visiting social network members.

Introduction: Cross-border mobility (CBM) to visit social network members or for everyday activities is an important part of daily life for citizens in border regions, including the Meuse-Rhine Euroregion (EMR: neighboring regions from the Netherlands, Belgium, and Germany). We assessed changes in CBM during the COVID-19 pandemic and how participants experienced border restrictions. Methods: Impact of COVID-19 on the EMR' is a longitudinal study using comparative cross-border data collection. In 2021, a random sample of the EMR-population was invited for participation in online surveys to assess current and pre-pandemic CBM. Changes in CBM, experience of border restrictions, and associated factors were analyzed using multinomial and multivariable logistic regression analysis. Results: Pre-pandemic, 82% of all 3,543 participants reported any CBM: 31% for social contacts and 79% for everyday activities. Among these, 26% decreased social CBM and 35% decreased CBM for everyday activities by autumn 2021. Negative experience of border restrictions was reported by 45% of participants with pre-pandemic CBM, and was higher (p < 0.05) in Dutch participants (compared to Belgian; aOR= 1.4), cross-border [work] commuters (aOR= 2.2), participants with cross-border social networks of friends, family or acquaintances (aOR= 1.3), and those finding the measures 'limit group size' (aOR= 1.5) and 'minimalize travel' (aOR= 2.0) difficult to adhere to and finding 'minimalize travel' (aOR= 1.6) useless. Discussion: CBM for social contacts and everyday activities was substantial in EMR-citizens, but decreased during the pandemic. Border restrictions were valued as negative by a considerable portion of EMR-citizens, especially when having family or friends across the border. When designing future pandemic control strategies, policy makers should account for the negative impact of CBM restrictions on their citizens.

[Multi-resistant Enterobacterales and travel]. / Entérobactéries multirésistantes et voyage.

Multi-resistant Enterobacterales (MRE) are on the increase worldwide, with the main mechanism of resistance acquisition being horizontal transfer of plasmids coding for extended-spectrum betalactamase and/or carbapenemase. Low- and middle-income countries are the most affected, but surveillance in low-endemicity countries, such as Switzerland, is essential. International travel is one of the sources of MRE dissemination in the community, with the main risk factors for acquiring MRE being a stay in South or Southeast Asia and the use of antibiotics during travel. Other factors, notably animal and environmental, also explain this increase. Measures encompassing a One Health approach are therefore needed to address this issue.

Les entérobactéries multirésistantes (EMR) sont en augmentation dans le monde, avec comme mécanisme principal d'acquisition de résistance le transfert horizontal de plasmides codant pour une bêtalactamase à spectre étendu et/ou une carbapénèmase. Les pays à bas et moyens revenus sont les plus touchés, mais une surveillance dans les pays à faible endémicité, comme la Suisse, est essentielle. Les voyages internationaux sont l'une des sources de dissémination d'EMR dans la communauté, avec comme facteurs de risque principaux d'acquisition d'EMR un séjour en Asie du Sud ou du Sud-Est et l'utilisation d'antibiotiques durant le voyage. D'autres facteurs, notamment animaliers et environnementaux, expliquent aussi cette augmentation. Ainsi, il est nécessaire que des mesures englobant une approche « One Health ¼ répondent à cette problématique.

[Marburg virus disease in travellers]. / Maladie à virus Marburg chez les voyageurs.

Marburg virus disease (MVD) is a dreadful but exceptional disease. Formerly mainly identified in Uganda, Angola and the Democratic Republic of Congo, it has recently appeared in the Republic of Guinea, Ghana, Equatorial Guinea and Tanzania, adding West Africa to the affected regions. Humans become infected through exposure to bats Roussettus aegyptiacus or during unprotected care of infected people. Five cases are linked to travellers, the last one dates to 2008 and involved a visit to caves colonized by bats. At present, there is no specific treatment or vaccine. Despite its rarity, adventurous travelers should be aware of the risks of exposure and avoid entering places inhabited by bats.

La maladie à virus Marburg est une maladie redoutable mais exceptionnelle. Autrefois identifiée en Ouganda, Angola et République démocratique du Congo, elle a récemment fait son apparition en République de Guinée, au Ghana, en Guinée équatoriale et en Tanzanie, ajoutant l'Afrique de l'Ouest aux régions touchées. Les humains s'infectent lors d'une exposition avec les chauves-souris roussettes d'Égypte ou lors de la prise en charge sans protection de personnes infectées. Cinq cas sont liés à des voyageurs, le dernier remonte à 2008 et était associé à la visite de grottes colonisées par des roussettes d'Égypte. Actuellement, il n'existe aucun traitement spécifique ni vaccin. Malgré sa rareté, les voyageurs aventureux doivent être informés des risques d'exposition et éviter de pénétrer dans des lieux habités par des chauves-souris.

Medical Events Encountered at a Major International Airport and Health Services Provided.

INTRODUCTION: Travel by airline starts and ends at airports. Thousands of people consisting of passengers, relatives of passengers, and employees gather at airports every day. In this study, medical events (MEs) encountered at Istanbul Atatürk Airport (IAA) and health services provided were analyzed.METHODS: The MEs encountered in IAA between January 1, 2016, and December 31, 2018, and health services provided by the private medical clinic in the airport terminal building were retrospectively analyzed.RESULTS: During the study period, 192,500,930 passengers traveled from the IAA and a total of 11,799 patients were seen at the clinic. There were 4898 (41.5%) male patients. The median age of the 9466 (80.2%) patients whose age was recorded was 34 (28-51) yr. Of 11,799 patients included in the present study, 9228 (78.21%) patients had medical complaints, 1122 (9.5%) patients had trauma complaints, 1180 patients (10%) were transferred to the hospital, and 269 (2.27%) patients required a certificate of preflight fitness. The most common medical complaint was gastrointestinal (1515 patients, 12.84%). The most common trauma was soft tissue injury (345 patients, 2.92%).DISCUSSION: MEs in airports can be as various and also critical as health conditions seen in emergency departments. It is important to provide medical services with an experienced medical team trained in aviation medicine and adequate medical equipment at airports.Ceyhan MA, Demir GG, Cömertpay E, Yildirimer Y, Kurt NG.

Differences in tourism economic development and its influencing factors among three major city clusters along the middle reaches of the Yangtze River.

An in-depth study of the mechanisms governing the generation, evolution, and regulation of differences in tourism economics holds significant value for the rational utilization of tourism resources and the promotion of synergistic tourism economic development. This study utilizes mathematical statistical analysis and GIS spatial analysis to construct a single indicator measure and a comprehensive indicator measure to analyze tourism-related data in the research area from 2004 to 2019. The main factors influencing the spatial and temporal differences in the tourism economy are analyzed using two methods, namely, multiple linear regression and geodetector. The temporal evolution, overall differences and differences within each city group fluctuate downwards, while the differences between groups fluctuate upwards. Domestic tourism economic differences contribute to over 90% of the overall tourism economic differences. Spatial divergence, the proportion of the tourism economy accounted for by spatial differences is obvious, the comprehensive level of the tourism economy can be divided into five levels. The dominant factors in the formation of the pattern of spatial and temporal differences in the tourism economy are the conditions of tourism resources based on class-A tourist attractions and the level of tourism industry and services based on star hotels and travel agencies. This study addresses the regional imbalance of tourism economic development in city clusters and with the intent of promoting balanced and high-quality development of regional tourism economies.

Impact of a teaching hospital-based multidisciplinary telemedicine programme in Southwestern Colombia: a cross-sectional resource analysis.

BACKGROUND: Telemedicine, a method of healthcare service delivery bridging geographic distances between patients and providers, has gained prominence. This modality is particularly advantageous for outpatient consultations, addressing inherent barriers of travel time and cost. OBJECTIVE: We aim to describe economical outcomes towards the implementation of a multidisciplinary telemedicine service in a high-complexity hospital in Latin America, from the perspective of patients. DESIGN: A cross-sectional study was conducted, analysing the institutional data obtained over a period of 9 months, between April 2020 and December 2020. SETTING: A high-complexity teaching hospital located in Cali, Colombia. PARTICIPANTS: Individuals who received care via telemedicine. The population was categorised into three groups based on their place of residence: Cali, Valle del Cauca excluding Cali and Outside of Valle del Cauca. OUTCOME MEASURES: Travel distance, time, fuel and public round-trip cost savings, and potential loss of productivity were estimated from the patient's perspective. RESULTS: A total of 62 258 teleconsultations were analysed. Telemedicine led to a total distance savings of 4 514 903 km, and 132 886 hours. The estimated cost savings were US$680 822 for private transportation and US$1 087 821 for public transportation. Patients in the Outside of Valle del Cauca group experienced an estimated average time savings of 21.2 hours, translating to an average fuel savings of US$149.02 or an average savings of US$156.62 in public transportation costs. Areas with exclusive air access achieved a mean cost savings of US$362.9 per teleconsultation, specifically related to transportation costs. CONCLUSION: Telemedicine emerges as a powerful tool for achieving substantial travel savings for patients, especially in regions confronting geographical and socioeconomic obstacles. These findings underscore the potential of telemedicine to bridge healthcare accessibility gaps in low-income and middle-income countries, calling for further investment and expansion of telemedicine services in such areas.

The influence of progeny-Parents family travel on the well-being of the elderly in filial piety culture.

Grounded in the cultural context of Chinese filial piety, this study employs structural equation model to analyze survey data from elderly participants. It explores the effect and path of progeny-parents family travel on the elderly's sense of well-being and examines the mediating roles of generational interaction, optimistic emotion, and psychological resilience. The findings indicate that progeny-parents family travel positively influences the well-being of the elderly, with generational interaction, optimistic emotion, and psychological resilience serving as intermediary roles. Theoretically, this study enriches the localized perspective of family travel's psychological and behavioral impact on the elderly. It elucidates the spillover effects of family travel within the framework of filial piety culture, delineates the mechanisms by which family travel enhances elderly well-being, and offers theoretical insights for businesses to develop customized family travel products and services.

SARS-CoV-2 variant introduction following spring break travel and transmission mitigation strategies.

BACKGROUND: University spring break carries a two-pronged SARS-CoV-2 variant transmission risk. Circulating variants from universities can spread to spring break destinations, and variants from spring break destinations can spread to universities and surrounding communities. Therefore, it is critical to implement SARS-CoV-2 variant surveillance and testing strategies to limit community spread before and after spring break to mitigate virus transmission and facilitate universities safely returning to in-person teaching. METHODS: We examined the SARS-CoV-2 positivity rate and changes in variant lineages before and after the university spring break for two consecutive years. 155 samples were sequenced across four time periods: pre- and post-spring break 2021 and pre- and post-spring break 2022; following whole genome sequencing, samples were assigned clades. The clades were then paired with positivity and testing data from over 50,000 samples. RESULTS: In 2021, the number of variants in the observed population increased from four to nine over spring break, with variants of concern being responsible for most of the cases; Alpha percent composition increased from 22.2% to 56.4%. In 2022, the number of clades in the population increased only from two to three, all of which were Omicron or a sub-lineage of Omicron. However, phylogenetic analysis showed the emergence of distantly related sub-lineages. 2022 saw a greater increase in positivity than 2021, which coincided with a milder mitigation strategy. Analysis of social media data provided insight into student travel destinations and how those travel events may have impacted spread. CONCLUSIONS: We show the role that repetitive testing can play in transmission mitigation, reducing community spread, and maintaining in-person education. We identified that distantly related lineages were brought to the area after spring break travel regardless of the presence of a dominant variant of concern.

Autochthonous and imported giardiasis cases: An analysis of two decades of national surveillance data, Germany, 2002 to 2021.

BackgroundGiardia duodenalis is a major cause of gastroenteritis globally, and is the most common food- and waterborne parasitic infection in Europe.AimTo describe the epidemiology of reported acute giardiasis cases in Germany and compare demographic and clinical characteristics between imported and autochthonous cases.MethodsWe conducted a descriptive analysis of giardiasis cases that fulfilled the national case definition and were reported between January 2002 and December 2021. We defined an imported case as having at least one place of exposure abroad in the 3-25 days before symptom onset. We analysed case numbers and incidence by age, sex, month reported and geographic region, both overall and stratified by autochthonous and imported cases.ResultsFrom 2002 to 2021, 72,318 giardiasis cases were reported in Germany, corresponding to a mean annual incidence of 4.4 per 100,000 population. Annual incidence gradually decreased since 2013, declining sharply during the COVID-19 pandemic in 2020-21. Of 69,345 cases reported between 2002 and 2019, 35% were imported. Incidence of autochthonous cases (overall yearly mean: 3.1/100,000) was highest in males and young children (< 5 years); imported cases were predominantly adults aged 20-39 years. We identified seasonal patterns for imported and autochthonous cases.ConclusionsGiardiasis in Germany is typically assumed to be imported. Our data, however, underline the importance of autochthonous giardiasis. Travel advice might reduce imported infections, but prevention strategies for autochthonous infections are less clear. Dietary, behavioural and environmental risk factors need to be further investigated to enhance infection prevention measures for autochthonous giardiasis.

Notes from the Field: Increases in Imported Malaria Cases - Three Southern U.S. Border Jurisdictions, 2023.

Malaria is a severe and potentially fatal mosquitoborne disease caused by infection with Plasmodium spp. parasites. Although malaria is no longer endemic in the United States, imported infections are reported annually; the primary risk group has been U.S. residents traveling to areas where malaria is endemic (1). In 2023, sporadic locally acquired mosquito-transmitted malaria cases were reported in several U.S. states (2,3). This report describes increases in imported malaria cases in 2023 compared with 2022 in three public health jurisdictions along the U.S. southern border.
