Prevalence, Intensity, and Sex Differences in Travel Related Stressors

The Outbreak of Digital Detox Motives and Their Public Health Implications for Holiday Destinations

This paper aims to analyze the external and objective barriers of the digital difference between being at home and being on holiday, and the intrinsic and subjective inhibitors to remaining online once at a destination. In this study, the literature is thoroughly reviewed, going beyond the traditional economic and technological explanations, along with those related to skill, to consider those rooted in well-being and psychology. Hence, a more integrative and exhaustive framework deals with how tourists approach their perceived hazardous and oversaturating digital environment. Finally, the role played by sociodemographics is studied by profiling those who are predisposed toward disconnecting in order to preserve their wellness. In total, 346 tourists were surveyed at random, with proportional stratification, on the island of Gran Canaria. The measuring instrument comprised a questionnaire whose scales gathered information about more than eighteen devices, twenty-eight social media platforms, and sixteen device and social media barriers. The obtained evidence demonstrates how crucial “detox” motivations are when trying to elucidate the differences in digital behavior between their home and holiday destination. Similarly, the evidence highlights that while gender, age, nationality, and income are associated with these differences, education is not. This study pioneers an analysis of the detox barrier regarding staying connected while on holiday and provides insight into how this intrinsic and subjective inhibitor interacts with other external hindrances to people’s health, both where they live and where they travel.

Travelling with heart failure: risk assessment and practical recommendations

Patients with heart failure are at a higher risk of cardiovascular events compared with the general population, particularly during domestic or international travel. Patients with heart failure should adhere to specific recommendations during travel to lower their risk of developing heart failure symptoms. In this Review, we aim to provide clinicians with a set of guidelines for patients with heart failure embarking on national or international travel. Considerations when choosing a travel destination include travel distance and time, the season upon arrival, air pollution levels, jet lag and altitude level because all these factors can increase the risk of symptom development in patients with heart failure. In particular, volume depletion is of major concern while travelling given that it can contribute to worsening heart failure symptoms. Pre-travel risk assessment should be performed by a clinician 4-6 weeks before departure, and patients should receive advice on potential travel-related illness and on strategies to prevent volume depletion. Oxygen supplementation might be useful for patients who are very symptomatic. Upon arrival at the destination, potential drug-induced photosensitivity (particularly in tropical destinations) and risks associated with the local cuisine require consideration. Special recommendations are needed for patients with cardiac implantable electronic devices or left ventricular assist devices as well as for those who have undergone major cardiac surgery.

Individual differences in the temporal progression of motion sickness and anxiety: the role of passengers' trait anxiety and motion sickness history

The objective of the study is to show that trait anxiety and motion sickness history are responsible for different temporal progressions of sickness in passengers. The level of inflight anxiety and inflight sickness severity was monitored for 124 passengers in a full-motion cabin simulator during a short-haul flight with four different flight segments. Four groups with different characteristics in trait anxiety and motion sickness susceptibility showed different profiles of inflight sickness development. High trait anxiety was responsible for high inflight anxiety and a constantly high level of motion sickness, while passengers with just a motion sickness history showed an increase in motion sickness severity over time. We suggest that trait anxiety and motion sickness susceptibility interact and have an impact on the temporal progression of inflight sickness severity. The analysis of temporal developments of anxiety and sickness are fruitful for understanding the origins of motion sickness, research and individual treatments. Practitioner summary: In a full-motion cabin simulator study with 124 passengers the level of inflight anxiety and inflight sickness severity was monitored. Trait anxiety and motion sickness history were found to have different impacts on the temporal progression of individual sickness severity.

Mortality from malaria in France, 2005 to 2014

Introduction

Malaria is a notifiable disease in all European Union and European Economic Area countries except Belgium and France, where only autochthonous malaria is notifiable. Although morbidity caused by malaria has been assessed, little is known about mortality incidence.

Objective

Our aim was to estimate the number of imported malaria-related deaths in hospital in metropolitan France.

Methods

We matched individual deaths reported between 1 January 2005 and 31 December 2014 to the French National Reference Centre for malaria (FNRCm) with malaria-related deaths from two other sources: the French National Registry on medical causes of death and the French national hospital discharge database. A capture–recapture method with log-linear modelling was used. Age, sex and place of death stratification were applied to remove heterogeneity.

Results

The estimated malaria-related deaths in metropolitan France during the study period were 205 (95% confidence interval (CI): 191–219). The annual mean number of malaria-related deaths was estimated at 21 (95% CI: 19–22). The FNRCm malaria-related deaths surveillance had a 38% sensitivity (95% CI: 32–44). Among 161 in-hospital individual malaria-related deaths reported from three data sources, the sex ratio (male to female) was 2.6. Median age of the patients was 57 years, ranging from 1 to 89 years.

Conclusion

The pertinent finding of this report is that malaria-related death records were significantly more complete than case records. Therefore, data comparison of imported malaria morbidity and mortality between countries should imperatively be assessed using standard indicators weighted according to the completeness of health surveillance systems.

The Effect of Hajj Trip on Mental Health: A Longitudinal Study

Hajj is a spiritual journey and religious ritual which is performed every year. Here, we evaluate the psychological effect of the Hajj. Using General Health Questionnaire (GHQ) questionnaire with 28 questions, the mental health of the pilgrims was assessed before and after the journey. A total of 154 people were questioned, 72 pilgrims (47%) were male. The mean GHQ score of participants before the journey was 50.1 and after the journey was 49.5 (P = 0.248). The results of analysis of variance and generalized estimating equation indicated that the GHQ scores had no significant difference before and after the journey.

Patients with mental problems - the most defenseless travellers

BACKGROUND

Severe mental illness occurring abroad is a difficult situation for patients, their families, and for the local medical community. Patients with mental problem are doublely stigmatized due to their mental illness and because they are foreigners in an unfamiliar country. The appropriate treatment is often delayed, while patients are often dealt with in a manner that violates their human rights. Moreover, repatriation - which is vital in this case - is often delayed due to the lack of international protocols for the transportation and treatment of mentally ill travelers.

METHODS

Authors analyzed several factors related to acute mental health problems during travel: the etiology of symptoms, the appropriate treatment possibilities abroad, and medical evacuation and repatriation of the psychotic patient. The article presents a brief review of travel-related mental disorders, the epidemiology of mental health issues faced by travelers, and the significance of pre-travel advice for these patients. The first problem is to recognize (and redress) the particular challenges faced by a psychotic patient in a strange country. The second challenge is to prepare the patients, often in a poor psychiatric state, for medical evacuation by commercial aircraft. Another important question is the best way to take the patient through customs and security control. All of these, as yet unresolved, issues can make the mental patient virtually defenseless.

CONCLUSIONS

Although timely repatriation of a mentally ill patient is vital and urgent, most travel insurance policies exclude treatment and repatriation costs incurred due to acute mental illness. The high cost of treatment and repatriation must be paid by the patient or their family, which could lead to severe financial strain or insolvency. Changing the approaches taken by the local mental health care community, police, airport security, and insurance companies remain a challenge for psychiatrists.

A Survey of the Health Experiences of International Business Travelers

Occupational health professionals need to know more about the health, worklife, and family life of international business travelers (IBTs). This descriptive correlational study, in two parts, examines the physiological and psychosocial experiences associated with business travel for a sample of 140 employees from western Canada's oil and gas industry. Results for Part One show that 76% of IBTs report travel related health problems, 74% have jet lag, 45% have travelers' diarrhea and gastrointestinal complaints, 12% to 16% have climate adaptation problems, and 2% report accidents and minor injuries. High risk behaviors include not carrying a first aid travel kit (54%); drinking more alcohol than ordinarily (21%); and neglecting food, water, and antimalarial precautions (6% to 14%). Other risk factors include age, length of stay, destination, pre-travel medical examinations, pre-travel advice, and eating and accommodation facilities. Findings show that IBTs are at risk for travel related physiological health problems. Implications for practitioners call for increased occupational health expertise in pre-travel preparation, follow up post-travel and regular health surveillance for employees who travel on international business.

Response to Hepatitis A Vaccination in Immunocompromised Travelers

BACKGROUND

Hepatitis A vaccines are highly immunogenic in healthy patients, but there is uncertainty about their immunogenicity in immunocompromised patients.

METHODS

Our study included immunocompromised patients who received 1 or 2 hepatitis A vaccinations between January 2011 and June 2013. We assessed factors that influenced the serologic response to vaccination. We performed a literature review of previous studies on hepatitis A vaccination in immunocompromised patients.

RESULTS

Of 85 immunocompromised patients, 65 used immunosuppressive drugs, 13 had received stem cell transplants, and 7 were infected with human immunodeficiency virus. After vaccination, 65 of 85 (76.5%) developed antibodies. Tumor necrosis factor α blocker use was associated with better serologic responses than other immunosuppressive drugs. Female patients were more compliant than male patients with postvaccination antibody titer measurements. In 11 relevant studies, antibody responses after the first and second vaccination averaged 37% and 82%, respectively. Factors that negatively influenced serologic response rates were high doses of immunosuppressive drugs, fewer hepatitis A vaccinations, and a short interval between vaccination and antibody measurement.

CONCLUSIONS

Immunocompromised patients showed moderate to good serologic responses to hepatitis A vaccination, but may need more time to develop immunity. Tumor necrosis factor α blocker use was associated with better antibody responses than other drugs. Specifically, male patients should be motivated to return for antibody titer measurements.

Risk factors and pre-travel healthcare of international travellers attending a Dutch travel clinic: a cross-sectional analysis

BACKGROUND

The number of international travellers is currently estimated to exceed one billion annually. To address travel related health risks and facilitate risk reduction strategies, detailed knowledge of travellers' characteristics is important.

METHOD

In this cross-sectional study, data of a 20% sample of travellers visiting the Academic Medical Center (AMC) travel clinic Amsterdam from July 2011 to July 2012 was collected. Itineraries and protection versus exposure rates of preventable infectious diseases were mapped and reported according to STROBE guidelines.

RESULTS

1749 travellers were included. South-Eastern Asia, South-America and West-Africa were most frequently visited. 26.2% of the population had pre-existing medical conditions (often cardiovascular). Young and VFR travellers had a longer median travel time (28 and 30 days) compared to the overall population (21 days). Young adult travellers were relatively often vaccinated against hepatitis B (43.9% vs. 20.5%, p < .001) and rabies (16.6% vs. 4.3%, p < .001). VFRs were less often vaccinated against hepatitis B (11.6% vs. 30.6%, p < .001) and rabies (1.3% vs. 9.0%, p .012) compared to non-VFR travellers.

CONCLUSIONS

Pre-travel guidelines were well adhered to. Young adult travellers had high-risk itineraries but were adequately protected. Improvement of hepatitis B and rabies protection would be desirable, specifically for VFRs.

[Psychiatric patient: the most vulnerable traveller]

Authors analyse questions of medical evacuation of the psychotic patient from abroad to homeland. This task can be considered the most difficult problem for the attending physician and the escorting medical team as well. The main challenge is to recognise the psychotic patient in a foreign country with a different health-care system and to overcome the language barrier and the different cultural background. The second issue is to prepare the patients - who are usually in a poor condition - for the medical evacuation by commercial aircraft. Another important issue is to take the patient through the strict security control. All of these (partially unsolved) problems make the mentally ill patient defenceless. Although the repatriation of a mentally ill patient is vital and urgent, travel insurance policy mostly excludes to cover the cost of treatment and repatriation. The high cost of treatment and repatriation of the patient should be paid by the patient or the family, who are often in the position of insolvency. In this paper authors present the history of a patient and give a brief review on travel-related mental disorders, the epidemiology of mental alterations during travel as well as the problems of appropriate evacuation. Authors conclude that there is a need for a better approach of the airport authorities and insurance decision makers to the mentally ill patient travelling abroad.

Are the flight security measures good for the patients? The “sickurity” problem

Az egyre szigorúbb biztonsági intézkedések a repülőtereken az utasokat is egyre súlyosabban érintik. Az életbe léptetett megszorítások (a folyadék, illetve a mozgás korlátozása) felerősíthetik a repülőgéppel utazók szervezetében fellépő káros élettani folyamatokat, a legújabb vizsgálati eljárások (például a teljestest-szken) pedig – a kétségtelen etikai és morális aggályok mellett – olyan patológiai folyamatokat indíthatnak el, amelyek későbbi hatása még nem teljesen ismert. Fokozottan igaz ez arra az utazóra, aki útja során betegszik meg vagy éri sérülés, és emiatt nem folytathatja útját. Az ilyen utazót – megfelelő előkészítés után – haza kell szállítani. A hazaszállítás leggyakrabban a menetrendszerű repülőgépen történik, fekvő beteg esetében a kabinban elhelyezett hordágyon, egészségügyi kísérettel. Ez a hazaszállítási mód több biztonsági problémát vet fel: a beteg ellenőrzésén kívül a kísérő egészségügyi felszerelésének ellenőrzését is. Az orvosi táska ugyanis több olyan eszközt, gyógyszert tartalmaz, amelyek repülőgépre vitele tilos. Egységes rendelkezés hiányában ezeket a problémákat a biztonsági személyzet változatos módon kezeli: a skála az empatikus hozzáállástól a kategorikus tiltásig terjed. Szükséges tehát egy olyan szakmai állásfoglalás, amely figyelembe veszi a repülésbiztonság (security) mellett a beteg ember út közbeni ellátásának biztonságát (sickurity) is, és ezáltal kiküszöböli a beteg és kísérőjének kiszolgáltatottságát. Ugyanez érvényes a fogyatékkal élők utazására is. A közlemény nemcsak a nehézségeket veti fel, hanem megpróbálja feloldani az utasbiztonság és a betegbiztonság egymásnak sokszor ellentmondó követelményeit, az úgynevezett „sickurity” problémát. Orv. Hetil., 2010,41,1702–1707.

Risk factors for psychological stress among international business travellers

OBJECTIVES

This study investigated sources of self reported psychological stress among international business travellers at the World Bank, following up on a previous study showing that travellers submitted more insurance claims for psychological disorders. Hypotheses were that work, personal, family, and health concerns, as well as time zone travel, contribute to travel stress.

METHODS

A travel survey was developed from focus groups and consisted of questions about these potential sources of travel stress. Surveys were sent to a random sample of staff, stratified by number of travel missions, age range, and sex. Canonical correlation analyses estimated the association between key survey items on sources of stress and two measures of travel stress.

RESULTS

498 staff completed the survey. More than a third reported high to very high travel stress. Correlations between predictors and travel stress showed that social and emotional concerns (such as impact of travel on family and sense of isolation) contributed the most to such stress, followed by health concerns, and workload upon return from travel. Surprisingly, time zone travel did not contribute to the self reported stress of these travellers. There were few modifiers of stress, although respondents suggested that a day of rest after travel and reduced workloads would help.

CONCLUSIONS

The current study confirms clinical impressions about several correlates of travel stress. Similar research with travellers in other organisations could help to determine whether the findings from this study are valid and what measures can be taken to reduce the psychological health risks to travellers.

Anxiety and health problems related to air travel

BACKGROUND

A significant proportion of air travelers experience situational anxiety and physical health problems. Take-off and landing are assumed to be stressful, but anxiety related to other aspects of the air travel process, anxiety coping strategies, and in-flight health problems have not previously been investigated.

METHODS

We aimed to investigate frequency of perceived anxiety at procedural stages of air travel, individual strategies used to reduce such anxiety, and frequency of health problems on short-haul and long-haul flights. A questionnaire measuring the occurrence and frequency of the above was administered to two samples of intending travelers during a 3 month period to: (a) 138 travel agency clients, and (b) 100 individuals attending a hospital travel clinic.

RESULTS

Of the 238 respondents, two thirds were women. Take-off and landing were a perceived source of anxiety for about 40% of respondents, flight delays for over 50%, and customs and baggage reclaim for a third of individuals. Most frequent anxiety-reduction methods included alcohol and cigarette use, and distraction or relaxation techniques. Physical health problems related to air travel were common, and there was a strong relationship between such problems and frequency of anxiety. Travel agency clients reported more anxiety but not more physical health symptoms overall than travel clinic clients. Women reported greater air-travel anxiety, and more somatic symptoms than men.

CONCLUSIONS

Significant numbers of air travelers report perceived anxiety related to aspects of travel, and this is associated with health problems during flights. Airlines and travel companies could institute specific measures, including improved information and communication, to reassure clients and thereby diminish anxiety during stages of air-travel. Medical practitioners and travel agencies should also be aware of the potential stresses of air travel and the need for additional information and advice.

Tolerability and Effectiveness of Malaria Chemoprophylaxis with Mefloquine or Chloroquine with or without Co-medication

Background: To determine the relevance of drug interactions with co-medication for effectiveness and tolerability of antimalarial chemoprophylaxis. Method: A database (MALPRO2) on travelers on their flight home from Africa to Europe between July 1988 and December 1991 was reanalyzed. It contains data on prophylaxis with mefloquine (n = 48,264), with chloroquine (6,752), with chloroquine plus proguanil (19,727), and with no prophylaxis (3,871). The comparison of rates of malaria incidence and adverse events (AEs) between users and nonusers of co-medication was expressed by relative risk (RR). Results: Fifty-three percent of travelers (63% of females, 43% of males) used co-medication in all prophylaxis groups, with an average of 1.35 additional drugs per person and about two AEs reported per person. With the exception of antidiarrheals plus mefloquine, malaria incidence with co-medication was lower (RR = 0.8) than without co-medication. In all regimens, the proportion of travelers reporting AEs was about 1.5-fold with co-medication (p<.01); that reporting severe AEs was twice as high as compared to with no co-medication. Mefloquine AE rates for various classes of co-medication were similar to that of chloroquine, with highest AE and severity rates with neuropsychiatric drugs (excluding antiepileptics, RR = 1.9 and 2.9), and lowest rates with cardiovasculars (RR = 1.1 and 1.0). Various co-medications were used with different frequencies in males and females, and the latter reported more AEs. Conclusion: These data suggest that co-medications commonly used by travelers have no significant clinical impact on safety and effectiveness of prophylaxis with mefloquine or chloroquine. Increased frequency and severity of AEs when using co-medication rather is explained by underlying illness.
