Abstract Background Estimates of travel-related illness have focused predominantly on populations from highly developed countries visiting low- or middle-income countries, yet travel to and within high-income countries is very frequent. Despite being a top international tourist destination, few sources describe the spectrum of infectious diseases acquired among travellers to the USA. Methods We performed a descriptive analysis summarizing demographic and travel characteristics, and clinical diagnoses among non-US-resident international travellers seen during or after travel to the USA at a GeoSentinel clinic from 1 January 1997 through 31 December 2016. Results There were 1222 ill non-US-resident travellers with 1393 diagnoses recorded during the 20-year analysis period. Median age was 40 (range 0–86 years); 52% were female. Patients visited from 63 countries and territories, most commonly Canada (31%), Germany (14%), France (9%) and Japan (7%). Travellers presented with a range of illnesses; skin and soft tissue infections of unspecified aetiology were the most frequently reported during travel (29 diagnoses, 14% of during-travel diagnoses); arthropod bite/sting was the most frequently reported after travel (173 diagnoses, 15% after-travel diagnoses). Lyme disease was the most frequently reported arthropod-borne disease after travel (42, 4%). Nonspecific respiratory, gastrointestinal and systemic infections were also among the most frequently reported diagnoses overall. Low-frequency illnesses (<2% of cases) made up over half of diagnoses during travel and 41% of diagnoses after travel, including 13 cases of coccidioidomycosis and mosquito-borne infections like West Nile, dengue and Zika virus diseases. Conclusions International travellers to the USA acquired a diverse array of mostly cosmopolitan infectious diseases, including nonspecific respiratory, gastrointestinal, dermatologic and systemic infections comparable to what has been reported among travellers to low- and middle-income countries. Clinicians should consider the specific health risks when preparing visitors to the USA and when evaluating and treating those who become ill.

Diabetes mellitus is one of the major non-communicable diseases (NCD) with increasing prevalence in China. There is a lack of high-quality research focusing on prevention and management of diabetes in low and middle income countries (LMICs) compared to developed countries. This comparative study aims to describe the characteristics of diabetes research conducted in China and the USA. The study included 800 studies on diabetes mellitus from both countries. Compared with studies in the USA, studies in China were more likely to be laboratory-based primary research (50.5% versus 30.8%), more likely to use animal subjects (47% versus 27.5%), more likely to focused on risk factors (22.7% versus. 14.7%), more likely to be case-controlled studies (17.7% versus 10.0%), and more likely to evaluate pharmacological treatments (36.5% versus 20.7%). Further, compared with studies in the USA, studies in China were less likely to involve patients (42.7% versus 60.7%), less likely to be clinical trials (6.2% versus 14.5%), less likely to be cohort studies (8.8% versus. 26.0%), and less likely to evaluate disease management interventions (3.3% versus 13.3%). Clinical studies in China should be more patient-based to facilitate more effective control and management of diabetes.

The circumstances associated with falls among elderly people have been well described in some developed countries, but little is known about such accidents in middle-income countries. The aim of this paper is to report the circumstances and characteristics associated with falls leading to severe fractures among elderly people living in Rio de Janeiro, Brazil. Cases were obtained from two case-control studies on risk factors for severe fractures due to falls among individuals 60 years or older. Fallers were stratified according to clinical and socio-demographic variables and circumstances of the accident. Women comprised three-fourths of the sample. The femur was the most frequently fractured bone, more common among individuals over 70 years of age. Most falls occurred at home, between 6:00 AM and 6:00 PM, but the rooms where they occurred differed according to gender and age. Most individuals did not attribute their falls to tripping or slipping. This sample's data did not differ substantially from studies in developed countries.

Background:  Drowning is a serious and mostly preventable injury-related cause of death. Low-and-middle income countries represent 90% of total drowning deaths worldwide. There is lack of epidemiological studies of drowning in Nepal. The aim of this paper is to describe the status of drowning in Nepal. Methods: Cases of drowning, occurring between January 2013 and December 2015 were extracted from the Daily Incident Recording System of Nepal Police. Variables on age, sex of the deceased, types of water bodies, places, season when drowning occurred and activities of deceased were extracted and descriptive analysis was done. Results: A total of 1,507 drowning cases were recorded over a 3 year period. The rate of drowning was 1.9 per 100,000 (2.95 for males and 0.92 for females). Majority of drowning occurred among males (76%) and more than half were (53%) under 20 years of age. Mostly drowning occurred in rivers (natural water bodies). The findings provide strong indication that drowning occurs throughout the year in Nepal. Children were highly vulnerable to drowning. The magnitude of drowning was found to be lower than estimated by global burden of disease (GBD) study. Conclusion: The burden of drowning in Nepal is considerable, but mostly unknown to the public. Despite only having access to a limited data source, this study provides useful evidence that comprehensive research in Nepal is needed urgently.

In 2002, Richard Smith wrote an editorial, “publishing research from developing countries” in the Journal “Statistics in Medicine” highlighting the importance of research and publication from the developing countries (DCs).1 In that article, he mentioned the disparity in research and publication between the developed and developing countries. Almost two decades on, the problem still largely remains the same. It is estimated that more than 80% of the world’s population lives in more than 100 developing countries.2 In terms of disease burden, the prevalence and mortality from diseases in the low and middle-income countries are disproportionately high compared to developed countries.3 Although there is a high burden of disease, we base our treatment inferring results from research and publication from the developed countries which may not be fully generalizable due to geographical cultural, racial, and economic factors. This is where the problem lies.

Abstract BackgroundAccording to the Global Burden of Disease 2016 project, migraine ranks first for 15-49 years and second for all ages. The project has reported no significant relation with socio-economic status of a country. To the contrary, migraine ranks first for all ages in low- and middle-income countries suffering from civic unrest and conflict. This raises the question whether external stress factors may be correlated with migraine years lived with disability (YLD).MethodsIn the absence of cross-country studies on migraine and stress, this is a unique exploratory study. The analysis uses two country groups: developed countries (including some middle-income countries) and developing (middle- and low-income) countries. For the first group, proxy variables for stress are included that relate to flexible and highly competitive labour markets (productivity and unemployment), whereas for the second group, proxy variables are used that relate to conflict and migration. The data were analysed with multiple ordinary least squares cross-section regressions.ResultsThe results show a positive relationship between the stress variables on the one hand and migraine YLD on the other hand for both country groups. Almost all results are statistically significant at p<0.01.ConclusionsThe findings from the exploratory cross-country analysis suggest that societal stress factors may be potential candidates for modifiable factors for the prevalence and severity of migraine at the country level.

Emerging Patterns

This chapter aims at investigating the evolution of the digital divide within a set of developing countries between the years 2000 and 2005. In doing so, it moves away from the traditional analysis of the digital divide, which compares developed countries and developing countries, and examines the existing gap within a relatively homogeneous group of countries. On the basis of the theoretical and empirical contributions from scholars in different disciplines, we select a series of socioeconomic and technological indicators and provide an empirical assessment of the digitalization patterns in a set of 51 low income and lower-middle income countries. By means of cluster analysis techniques, we identify three emerging patterns of the digital divide and derive a series of policy implications, related to the implementation of an effective strategy to reduce digital backwardness. The characteristics of each pattern of digitalization can be also usefully employed to understand whether past interventions, especially in the area of competition policy, have been successful in addressing country-specific issues.

The Impact

The cost of logistics plays a vital role in the pricing of goods in international trade. Besides, the recent imposition of additional tariff by even upper-middle income countries such as the USA, China etc., has led to an increase in the total landed cost of goods. However, a seller has no option but to adapt to changing tariff requirements and can articulate only the logistics cost to a certain extent. This aspect requires an understanding of the logistics cost dynamics in international business. Since a higher volume of goods moves by marine transportation, this study focusses on the same. In this article, authors have attempted to establish a statistically significant relationship between prices and other factors like fuel, number of vessels, freight, and weight value ratio. The paper introduces a logistics-coefficient to indicate the extent of integration of logistics activities to keep the total-landed-cost (TLC) unchanged. Finally, the author proposes the system dynamics model to study the impact of changes in any one or some or all these factors on the price of the product. This model will enable the global firm to decide the entry and exit in the market. JEL Codes: F23
