Safety of helicopter transport in patients with acute coronary syndrome.

BACKGROUND: ST-elevation myocardial infarction (STEMI) systems of care have reduced inter-hospital transfer times and facilitated timely reperfusion goals. Helicopters may be an option when land transportation is not feasible; however, the safety of air transport in patients with acute coronary syndrome (ACS) is a factor to consider. OBJETIVES: The aim of this study was to evaluate the safety of helicopter transport for patients with ACS. METHODS: Prospective, observational, and descriptive study including patients diagnosed with ACS within the STEMI network of a metropolitan city transferred by helicopter to a large cardiovascular center to undergo percutaneous coronary intervention. The primary outcome of the study was the incidence of air-travel-related complications defined as IV dislodgement, hypoxia, arrhythmia, angina, anxiety, bleeding, and hypothermia. Secondary outcomes included the individual components of the primary outcome. RESULTS: A total of 106 patients were included in the study; the mean age was 54 years and 84.9% were male. The most frequent diagnosis was STEMI after successful fibrinolysis (51.8%), followed by STEMI with failed fibrinolysis (23.7%) and non-reperfused STEMI (9.4%). Five patients (4.7%) developed at least one complication: IV dislodgement (1.8%) and hypoxemia (1.8%) in two patients and an episode of angina during flight (0.9%). A flight altitude of > 10,000 ft was not associated with complications. CONCLUSIONS: The results of this study suggest that helicopter transportation is safe in patients undergoing acute coronary syndrome, despite the altitude of a metropolitan area.

ANTECEDENTES: Los sistemas de atención de IAMCEST han reducido los tiempos de transferencia interhospitalaria y han facilitado las metas de reperfusión oportuna. Los helicópteros pueden ser una opción cuando el transporte terrestre no es factible; sin embargo, la seguridad del transporte aéreo en pacientes con síndrome coronario agudo (SICA) es un factor a considerar. OBJETIVOS: Evaluar la seguridad del transporte en helicóptero para pacientes con SICA. MÉTODOS: Estudio prospectivo, observacional, descriptivo. Se incluyeron pacientes con diagnóstico de SICA dentro de la red IAMCEST en metrópolis extensa, trasladados en helicóptero a un centro cardiovascular. El resultado primario del estudio fue la incidencia de complicaciones relacionadas con los viajes aéreos definidas cómo desalojo de catéter intravenoso, hipoxia, arritmia, angina, ansiedad, sangrado e hipotermia. RESULTADOS: Total de 106 pacientes; la edad media fue de 54 años y 84,9% eran hombres. La altitud media de vuelo fue de 10,100 pies y la distancia media de vuelo fue de 50,0 km. El diagnóstico más frecuente fue IAMCEST tras fibrinolisis exitosa (51,8%), seguido de IAMCEST con fibrinolisis fallida (23,7%). Cinco pacientes (4,7%) desarrollaron una complicación: desalojo IV (1,8%) e hipoxemia (1,8%) en dos pacientes y un episodio de angina durante el vuelo (0,9%). Una altitud de vuelo mayor de 10,000 pies no se asoció a complicaciones. CONCLUSIONES: Los resultados de este estudio sugieren que el transporte en helicóptero es seguro en pacientes con SICA, incluso en altitudes > 10,000 pies.

Challenges Faced by Individuals with Hearing Impairment during COVID-19 Pandemic Lockdown in India - A Pilot Study.

COVID - 19 (Corona Virus Infectious Disease) situations reported in 2019, declared by World Health Organization (WHO) as a pandemic is still a prevailing global crisis. Common regulations were implemented such as lockdown, wearing face masks as mandatory, face shields, gloves and maintaining physical and social distance in public places to reduce the spread of the virus. These pandemic induced challenges affected social communication, technical and behavioral aspects in lifestyle of people with hearing impairment. Along with medical, paramedical services, the crisis had challenged hearing, speech language pathology and therapy services too. The study aimed to explore the challenges that adults with hearing impairment had experienced during the pandemic and to suggest some practical solutions that can be implemented by audiologists. It is a questionnaire-based study with purposive sampling method employed in data collection. The questionnaire was administered on adult hearing aid users (mean age: 18 years) recruited for participation from different parts/ clinical setups across India. The outcome of the questionnaire did support the assumption that availing audiological services was difficult or impossible for most of the hearing aid users. Accessing batteries was reported to be the most frequent issue. Adequate level of hearing though hearing aid was important to them and clinical services could not be availed for long period of time due to travel related issues and closure of audiological services. Also, social isolation impacted on their quality of life and effective communication. As a possible solution most of the users chose tele services as a better solution.

Real-Time Epidemiology and Acute Care Need Monitoring and Forecasting for COVID-19 via Bayesian Sequential Monte Carlo-Leveraged Transmission Models.

COVID-19 transmission models have conferred great value in informing public health understanding, planning, and response. However, the pandemic also demonstrated the infeasibility of basing public health decision-making on transmission models with pre-set assumptions. No matter how favourably evidenced when built, a model with fixed assumptions is challenged by numerous factors that are difficult to predict. Ongoing planning associated with rolling back and re-instituting measures, initiating surge planning, and issuing public health advisories can benefit from approaches that allow state estimates for transmission models to be continuously updated in light of unfolding time series. A model being continuously regrounded by empirical data in this way can provide a consistent, integrated depiction of the evolving underlying epidemiology and acute care demand, offer the ability to project forward such a depiction in a fashion suitable for triggering the deployment of acute care surge capacity or public health measures, and support quantitative evaluation of tradeoffs associated with prospective interventions in light of the latest estimates of the underlying epidemiology. We describe here the design, implementation, and multi-year daily use for public health and clinical support decision-making of a particle-filtered COVID-19 compartmental model, which served Canadian federal and provincial governments via regular reporting starting in June 2020. The use of the Bayesian sequential Monte Carlo algorithm of particle filtering allows the model to be regrounded daily and adapt to new trends within daily incoming data-including test volumes and positivity rates, endogenous and travel-related cases, hospital census and admissions flows, daily counts of dose-specific vaccinations administered, measured concentration of SARS-CoV-2 in wastewater, and mortality. Important model outputs include estimates (via sampling) of the count of undiagnosed infectives, the count of individuals at different stages of the natural history of frankly and pauci-symptomatic infection, the current force of infection, effective reproductive number, and current and cumulative infection prevalence. Following a brief description of the model design, we describe how the machine learning algorithm of particle filtering is used to continually reground estimates of the dynamic model state, support a probabilistic model projection of epidemiology and health system capacity utilization and service demand, and probabilistically evaluate tradeoffs between potential intervention scenarios. We further note aspects of model use in practice as an effective reporting tool in a manner that is parameterized by jurisdiction, including the support of a scripting pipeline that permits a fully automated reporting pipeline other than security-restricted new data retrieval, including automated model deployment, data validity checks, and automatic post-scenario scripting and reporting. As demonstrated by this multi-year deployment of the Bayesian machine learning algorithm of particle filtering to provide industrial-strength reporting to inform public health decision-making across Canada, such methods offer strong support for evidence-based public health decision-making informed by ever-current articulated transmission models whose probabilistic state and parameter estimates are continually regrounded by diverse data streams.

Social determinants of health influencing the adherence to post-endoscopic mucosal resection surveillance.

BACKGROUND AND AIMS: Colorectal cancer (CRC) is a global health challenge, particularly in Alabama, where the incidence rates exceed national averages. This study investigated the factors influencing adherence to post-endoscopic mucosal resection (EMR) colonoscopies, focusing on travel distance and socioeconomic status. This study aimed to provide evidence-based insights to improve patient care in CRC management. METHODS: This retrospective study in a tertiary care referral center analyzed 465 patients who underwent EMR. The data included demographics, clinical details, and travel-related variables. Descriptive statistics, logistic regression, and spatial analysis were used to assess the factors affecting adherence. RESULTS: Of 465 patients, 36.6 % had adequate follow-up, 21.8 % had inadequate follow-up, and 41.6 % were lost to follow-up. Noteworthy demographic variations were observed, with median ages differing across adherence groups. Traveled distances showcased compelling insights, indicating a median distance of 22.2 miles for adequate follow-up, 15.7 miles for inadequate follow-up, and 31.6 miles for the lost-to-follow-up group (p<0.001). Longer travel distances were associated with better adherence. Longer travel distances from the hospital were associated with significantly lower odds of inadequate follow-up: 10-25 miles OR:0.29, 25-85 miles OR:0.35, and >80 miles OR:0.24 compared to the first quartile (<10 miles). Socioeconomic factors, particularly educational attainment, significantly influenced the follow-up rates. CONCLUSIONS: This study revealed suboptimal post-EMR follow-up rates and underscored the impact of travel distance and socioeconomic factors. Targeted interventions addressing distance-related barriers can enhance treatment adherence and ensure timely CRC surveillance after EMR. Further research is needed in diverse healthcare settings.

Facioscapulohumeral Muscular Dystrophy European Patient Survey: Assessing Patient Reported Disease Burden and Preferences in Clinical Trial Participation.

Background: Facioscapulohumeral muscular dystrophy (FSHD) is a genetic disorder characterized by progressive muscle weakness leading to permanent disability. There are no curative treatments, however, there are several upcoming clinical trials testing new therapies in FSHD. Objective: This study aimed to explore the disease burden and patient preferences of people with FSHD to ensure that clinical trials can be designed to include outcome measures that are relevant and important to patients. Methods: A survey was developed with a steering committee clinicians and physiotherapists with relevant experience in the disease, patient representatives, a registry expert and industry consultants. Themes of the survey included; participant demographics, disease progression and impact on function, factors encouraging or discouraging clinical trial participation, and positive outcomes of a clinical trial. Results: 1147 participants responded to the online survey, representing 26 countries across Europe and a range of disease severities. The study highlighted the key symptoms causing concern for FSHD patients - muscle weakness and mobility issues - reflecting what participants want targeted for future therapies. The need for clear information and communication throughout clinical trials was emphasised. Factors most encouraging trial participation included access to new investigational therapies, access to trial results and benefits for the FSHD community. Factors most discouraging trial participation included travel related issues and fear of side effects. Conclusions: The results from this study identify the patient reported burden of FSHD and should provide researchers and industry with areas of therapeutic research that would be meaningful to patients, as well as supporting the development of patient centric outcome measures in clinical trials.

Chikungunya infection in returned travellers: results from the geosentinel network, 2005-2020.

BACKGROUND: Chikungunya is an important travel-related disease because of its rapid geographical expansion and potential for prolonged morbidity. Improved understanding of the epidemiology of travel-related chikungunya infections may influence prevention strategies including education and vaccination. METHODS: We analysed data from travellers with confirmed or probable chikungunya reported to GeoSentinel sites from 2005 to 2020. Confirmed chikungunya was defined as a compatible clinical history plus either virus isolation, positive nucleic acid test or seroconversion/rising titre in paired sera. Probable chikungunya was defined as a compatible clinical history with a single positive serology result. RESULTS: 1202 travellers (896 confirmed and 306 probable) with chikungunya were included. The median age was 43 years (range 0-91; interquartile range [IQR]: 31-55); 707 (58.8%) travellers were female. Most infections were acquired in the Caribbean (28.8%), Southeast Asia (22.8%), South Central Asia (14.2%) and South America (14.2%). The highest numbers of chikungunya cases reported to GeoSentinel were in 2014 (28.3%), 2015 (14.3%) and 2019 (11.9%). The most frequent reasons for travel were tourism (n = 592; 49.3%) and visiting friends or relatives (n = 334; 27.7%). The median time to presentation to a GeoSentinel site was 23 days (IQR: 7-52) after symptom onset. In travellers with confirmed chikungunya and no other reported illnesses, the most frequently reported symptoms included musculoskeletal symptoms (98.8%), fever/chills/sweats (68.7%) and dermatologic symptoms (35.5%). Among 917 travellers with information available, 296 (32.3%) had a pretravel consultation. CONCLUSIONS: Chikungunya was acquired by international travellers in almost 100 destinations globally. Vector precautions and vaccination where recommended should be integrated into pretravel visits for travellers going to areas with chikungunya or areas with the potential for transmission. Continued surveillance of travel-related chikungunya may help public health officials and clinicians limit the transmission of this potentially debilitating disease by defining regions where protective measures (e.g. pretravel vaccination) should be strongly considered.

The provision of sexual and reproductive health information and services to travellers: an exploratory survey of Australian travel medicine clinicians.

BACKGROUND: International travel can increase the risk of exposure to infectious diseases including sexually transmissible infections (STI). Pre-travel medical consultation provides an opportunity for travel-related health risk assessments and advice. This study explored how travel medicine clinicians integrate sexual and reproductive health (SRH) services into clinical practice. METHODS: A convenience sample of travel medicine clinicians completed a cross-sectional survey online or via hard-copy disseminated at an annual national Australian travel medicine conference. RESULTS: Of the 67 respondents, most (n , 51; 76.1%) had a postgraduate qualification relevant to travel medicine and 55.2% (n , 37) had worked in travel medicine for over 10years. Only 22.4% (n , 15) reported conducting a SRH history/STI risk assessment for all travel patients. STI testing pre-departure was conducted on patient request (48, 71.6%), if symptomatic (32, 47.8%) or based on risk history (28, 41.8%). SRH information pre-departure was most frequently provided if prompted by patient questions (n , 42; 62.7%), or based on the patient's history (n , 37; 55.2%). Over half the sample (n , 40; 59.7%) expressed interest in further training in SRH. CONCLUSION: Providing and engaging with additional training may assist travel medicine clinicians to take a more proactive approach to SRH consultations and STI testing. Additional research is needed to explore models of care that will allow comprehensive SRH and STI services to be integrated into standard pre- and post-travel care.

Modelling the impact of sublingual immunotherapy versus subcutaneous immunotherapy on patient travel time and CO2 emissions in Sweden.

In Sweden, allergy immunotherapy (AIT) is available as either subcutaneous immunotherapy (SCIT) injections or sublingual immunotherapy (SLIT) tablets and is used to treat moderate-severe allergic rhinitis (AR). This study sought to determine treatment-related CO2 emissions and travel times in Swedish patients receiving either SCIT or SLIT-tablets. A list of specialized Swedish AR clinics that administer AIT was determined, and respective co-ordinates retrieved. Swedish municipality population data were obtained from a national database. The mean distance from each Swedish municipality to the nearest AR clinic was calculated, adjusted using a detour index, and weighted by estimated patient population size. Transport modality data were obtained from a Swedish urban transport study and CO2 emissions were obtained from Government sources. The mean number of annual SLIT-tablets and SCIT doses required were calculated based on product labels and clinical expert input. The annual number of healthcare professional interactions were layered into the model to estimate changes in mean patient travel time, distance, and travel-related CO2 emissions associated with using SCIT versus SLIT-tablets. Mean annual travel-related CO2 emissions were 410 tonnes (to two significant figures [s.f.]; standard deviation [SD] 90) with SLIT-tablets, versus 1700 tonnes (SD 380) for SCIT, resulting in mean annual savings of approximately 1300 tonnes (SD 290) of CO2 if all AIT patients were to receive SLIT-tablets instead of SCIT, over 380 times greater than 2021 average Swedish CO2 emissions per capita. Approximate mean annual travel times for patients taking SLIT-tablets were 66,500 h (three s.f.; SD 14,400), and 278,000 h (SD 60,200) for SCIT, resulting in mean annual savings of 211,000 h (SD 45,800) if all AIT patients were to receive SLIT-tablets instead of SCIT. Compared with SCIT injections, SLIT-tablets led to substantial reductions in treatment-related CO2 emissions and travel times for Swedish patients.

Abortion patients' decision making about where to obtain out-of-state care following Texas' 2021 abortion ban.

OBJECTIVE: To assess pregnant Texans' decisions about where to obtain out-of-state abortion care following the September 2021 implementation of Senate Bill 8 (SB8), which prohibited abortions after detectable embryonic cardiac activity. DATA SOURCE: In-depth telephone interviews with Texas residents ≥15 years of age who obtained out-of-state abortion care after SB8's implementation. STUDY DESIGN: This qualitative study explored participants' experiences identifying and contacting abortion facilities and their concerns and considerations about traveling out of state. We used inductive and deductive codes in our thematic analysis describing people's decisions about where to obtain care and how they evaluated available options. DATA COLLECTION: Texas residents self-referred to the study from flyers we provided to abortion facilities in Arkansas, Colorado, Kansas, Louisiana, Mississippi, New Mexico, and Oklahoma. We also enrolled participants from a concurrent online survey of Texans seeking abortion care. PRINCIPAL FINDINGS: Participants (n = 65) frequently obtained referral lists for out-of-state locations from health-care providers, and a few received referrals to specific facilities; however, referrals rarely included the information people needed to decide where to obtain care. More than half of the participants prioritized getting the soonest appointment and often contacted multiple locations and traveled further to do so; others who could not travel further typically waited longer for an appointment. Although the participants rarely cited state abortion restrictions or cost of care as their main reason for choosing a location, they often made sacrifices to lessen the logistical and economic hardships that state restrictions and out-of-state travel costs created. Informative abortion facility websites and compassionate scheduling staff solidified some participants' facility choice. CONCLUSIONS: Pregnant Texans made difficult trade-offs and experienced travel-related burdens to obtain out-of-state abortion care. As abortion bans prohibit more people from obtaining in-state care, efforts to strengthen patient navigation are needed to reduce care-seeking burdens as this will support people's reproductive autonomy.

Failure of artemether-lumefantrine therapy in travellers returning to Belgium with Plasmodium falciparum malaria: an observational case series with genomic analysis.

BACKGROUND: Failure of artemisinin-based combination therapy is increasingly reported in patients with Plasmodium falciparum malaria in sub-Saharan Africa. We aimed to describe the clinical and genomic characteristics of recent cases of P. falciparum malaria failing artemether-lumefantrine in Belgium. METHODS: Travel-related cases of malaria confirmed at the national reference laboratory of the Institute of Tropical Medicine, Antwerp, Belgium, were reviewed. All cases for which attending clinicians reported persistence (beyond Day 3 post-treatment initiation, i.e. early failure) or recrudescence (from Day 7 to 42, i.e. late failure) of P. falciparum parasites despite adequate drug intake were analysed. Both initial and persistent/recurrent samples were submitted to next generation sequencing to investigate resistance-conferring mutations. RESULTS: From July 2022 to June 2023, eight P. falciparum cases of failure with artemether-lumefantrine therapy were reported (early failure = 1; late failure = 7). All travellers were returning from sub-Saharan Africa, most (6/8) after a trip to visit friends and relatives. PfKelch13 (PF3D7_1343700) mutations associated with resistance to artemisinin were found in two travellers returning from East Africa, including the validated marker R561H in the patient with early failure and the candidate marker A675V in a patient with late failure. Additional mutations were detected that could contribute to decreased susceptibility to artemisinin in another three cases, lumefantrine in six cases and proguanil in all eight participants. Various regimens were used to treat the persistent/recrudescent cases, with favourable outcome. CONCLUSION: Within a 12-month period, we investigated eight travellers returning from sub-Saharan Africa with P. falciparum malaria and in whom artemether-lumefantrine failure was documented. Mutations conferring resistance to antimalarials were found in all analysed blood samples, especially against lumefantrine and proguanil, but also artemisinin. There is a pressing need for systematic genomic surveillance of resistance to antimalarials in international travellers with P. falciparum malaria, especially those experiencing treatment failure.

Disparities in access to high-volume parathyroid surgeons in the United States: A call to action.

BACKGROUND: Parathyroidectomy by a high-volume surgeon is associated with a reduced risk of perioperative complications and of failure to cure primary and secondary hyperparathyroidism. There are limited data on disparities in access to high-volume parathyroid surgeons in the United States. METHODS: We used publicly available 2019 Medicare Provider Utilization and Payment data to identify all surgeons who performed >10 parathyroidectomies for Medicare fee-for-service beneficiaries, anticipating that fee-for-service beneficiaries likely represent only a subset of their high-volume practices. High-volume parathyroid surgeon characteristics and geographic distribution were evaluated. Inequality in the distribution of surgeons was measured by the Gini coefficient. The association between neighborhood disadvantage, based on the Area Deprivation Index, and proximity to high-volume parathyroid surgeons was evaluated using a one-way analysis of variance with Bonferroni-corrected pairwise comparisons. A sensitivity analysis was performed restricting to high-volume parathyroid surgeons within each hospital referral region, evidence-based regional markets for tertiary medical care. RESULTS: We identified 445 high-volume parathyroid surgeons who met inclusion criteria with >10 parathyroidectomies for Medicare fee-for-service beneficiaries. High-volume parathyroid surgeons were 71% male sex, and 59.8% were general surgeons. High-volume parathyroid surgeons were more likely to practice in a Metropolitan Statistical Area with a population >1 million than in less populous metropolitan or rural areas. The number of high-volume parathyroid surgeons per 100,000 fee-for-service Medicare beneficiaries in the 53 most populous Metropolitan Statistical Areas ranged from 0 to 4.94, with the highest density identified in Salt Lake City, Utah. In 2019, 50% of parathyroidectomies performed by high-volume parathyroid surgeons were performed by 20% of surgeons in this group, suggesting unequal distribution of surgical care (Gini coefficient 0.41). Patients in disadvantaged neighborhoods were farther from high-volume parathyroid surgeons than those in advantaged neighborhoods (median distance: disadvantaged 27.8 miles, partially disadvantaged 20.7 miles, partially advantaged 12.1 miles, advantaged 8.4 miles; P < .001). This association was also shown in the analysis of distance to high-volume parathyroid surgeons within the hospital referral region (P < .001). CONCLUSION: Older adults living in disadvantaged neighborhoods have less access to high-volume parathyroid surgeons, which may adversely affect treatment and outcomes for patients with primary and secondary hyperparathyroidism. This disparity highlights the need for actionable strategies to provide equitable access to care, including improved regionalization of high-volume parathyroid surgeon services and easing travel-related burdens for underserved patients.

[Vaccines to prevent Ebola virus disease: current challenges and perspectives].

RELEVANCE: Ebola virus disease (EVD) is an acute infectious disease with an extremely high case fatality rate reaching up to 90%. EVD has become widely known since 2014-2016, when outbreak in West Africa occurred and led to epidemic, which caused travel-related cases on the territory of other continents. There are two vaccines against EVD, prequalified by WHO for emergency use, as well as a number of vaccines, approved by local regulators in certain countries. However, even with the availability of effective vaccines, the lack of data on immune correlates of protection and duration of protective immune response in humans and primates is limiting factor for effectively preventing the spread of EVD outbreaks. AIMS: This review highlights experience of use of EVD vaccines during outbreaks in endemic areas, summarizes data on vaccine immunogenicity in clinical trials, and discusses perspectives for further development and use of effective EVD vaccines.

Travel for abortion care: implications for clinical practice.

PURPOSE OF REVIEW: Traveling long distances to obtain abortion care due to restrictions and scarce availability is associated with significant obstacles. We review clinical strategies that can facilitate abortion access and outline considerations to ensure person-centered and equitable care. RECENT FINDINGS: Establishing a patient's gestational duration prior to travel may be beneficial to ensure they are eligible for their desired abortion method at the preferred facility or to determine if a multiday procedure is required. If a local ultrasound cannot be obtained prior to travel, evidence demonstrates people can generally estimate their gestational duration accurately. If unable to provide care, clinicians should make timely referrals for abortion. Integration of telemedicine into abortion care is safe and well regarded by patients and should be implemented into service delivery where possible to reduce obstacles to care. Routine in-person follow-up care is not necessary. However, for those who want reassurance, formalized pathways to care should be established to ensure people have access to care in their community. To further minimize travel-related burdens, facilities should routinely offer information about funding and practical support, emotional support, and legal resources. SUMMARY: There are many opportunities to optimize clinical practice to support those traveling for abortion care.

Case Report: An Imported Case of Typhoid Fever Combined with Rhabdomyolysis and Multiple Organ Lesions in China.

Here, we report a case of blood culture-confirmed typhoid fever, rhabdomyolysis, and multiple organ damage that arrived in our country from overseas. A 23-year-old male patient presented at our hospital with fever and muscle pain; the condition progressed rapidly. Six days after the onset of symptoms, the patient developed rhabdomyolysis and liver/kidney damage; levels of creatine kinase (CK; maximum peak: 729,869 U/L) and myoglobin (> 3,000 ng/mL) were extremely high, although the extent of renal damage was relatively mild. Blood culture showed Salmonella typhi. The patient received a combination of meropenem and levofloxacin anti-infective therapy, as well as fluid and nutritional metabolic support. He gradually recovered and was discharged after two negative blood cultures. This case highlights the fact that typhoid-induced rhabdomyolysis is a serious, life-threatening disease and that the levels of CK and myoglobin are useful indicators for evaluating typhoid-induced rhabdomyolysis. Clinicians should remain vigilant regarding travel-related illnesses associated with enteric fever.

The Ill Returning Traveler.

Approximately 1.8 billion people will cross an international border by 2030, and 66% of travelers will develop a travel-related illness. Most travel-related illnesses are self-limiting and do not require significant intervention; others could cause significant morbidity or mortality. Physicians should begin with a thorough history and clinical examination to have the highest probability of making the correct diagnosis. Targeted questioning should focus on the type of trip taken, the travel itinerary, and a list of all geographic locations visited. Inquiries should also be made about pretravel preparations, such as chemoprophylactic medications, vaccinations, and any personal protective measures such as insect repellents or specialized clothing. Travelers visiting friends and relatives are at a higher risk of travel-related illnesses and more severe infections. The two most common vaccine-preventable illnesses in travelers are influenza and hepatitis A. Most travel-related illnesses become apparent soon after arriving at home because incubation periods are rarely longer than four to six weeks. The most common illnesses in travelers from resource-rich to resource-poor locations are travelers diarrhea and respiratory infections. Localizing symptoms such as fever with respiratory, gastrointestinal, or skin-related concerns may aid in identifying the underlying etiology.

Orientia tsutsugamushi detected by microbiome diagnostics.

Scrub typhus is caused by the mite-borne bacterium Orientia tsutsugamushi. Imported cases have been suspected in Denmark but no diagnostic method has yet been available to confirm the diagnosis. This is a case report of a 38-year-old male admitted to hospital with high fever, severe malaise and headache after returning from Malaysia. Scrub typhus was suspected and the patient recovered after one week of doxycycline treatment. The pathogen was identified by use of microbiome 16S/18S rRNA next-generation sequencing on ethylenediamine tetraacetic acid (EDTA) blood, which in the future may serve an important role in the investigation of travel-associated infections.

The pregnant traveller: An overview of common preventable infections.

Pregnant travellers are often unaware of the various infections that can be acquired during travel and that pregnant people may be at increased risk of severe disease compared to their non-pregnant counterparts. Pregnant people often seek pre-travel counselling from their obstetrician or primary care physicians, who may not be well versed in travel medicine. This paper aims to provide information for maternity care providers regarding important travel-related food, water and mosquito-borne illnesses, including their prevention and treatment methods, equipping maternity care providers to confidently counsel prospective travellers during pregnancy.

Investigating the dynamic mechanism of user willingness to actively publish travel-related Electronic Word-of-Mouth (eWOM) on tourism platforms.

This study aims to uncover the dynamic mechanism of users' willingness to actively publish Electronic word-of-Mouth (eWOM) on tourism platform. For this, a model with system dynamics and structural equation methods were constructed and validated. It was found that perceived usefulness, utilizing attitude, participatory, social identity, tourism experience, and platform agenda settings all had significant and positive effects on eWOM users' willingness to actively publish eWOM on tourism platforms. However, perceived ease of use showed no effect. This study provides a reference paradigm for future studies on willingness to actively publish eWOM. The results bear implications for the management practices of tourism platforms operators and tourism destination operators. It also helps platform operators to develop relevant strategies for recovering the tourism industry in the post-COVID-19 era.
