BACKGROUND:
The ongoing new coronavirus pneumonia (Corona Virus Disease 2019, COVID-19) outbreak is spreading in China, but it has not yet reached its peak. Five million people emigrated from Wuhan before lockdown, potentially representing a source of virus infection. Determining case distribution and its correlation with population emigration from Wuhan in the early stage of the epidemic is of great importance for early warning and for the prevention of future outbreaks.
METHODS:
The official case report on the COVID-19 epidemic was collected as of January 30, 2020. Time and location information on COVID-19 cases was extracted and analyzed using ArcGIS and WinBUGS software. Data on population migration from Wuhan city and Hubei province were extracted from Baidu Qianxi, and their correlation with the number of cases was analyzed.
RESULTS:
The COVID-19 confirmed and death cases in Hubei province accounted for 59.91% (5806/9692) and 95.77% (204/213) of the total cases in China, respectively. Hot spot provinces included Sichuan and Yunnan, which are adjacent to Hubei. The time risk of Hubei province on the following day was 1.960 times that on the previous day. The number of cases in some cities was relatively low, but the time risk appeared to be continuously rising. The correlation coefficient between the provincial number of cases and emigration from Wuhan was up to 0.943. The lockdown of 17 cities in Hubei province and the implementation of nationwide control measures efficiently prevented an exponential growth in the number of cases.
CONCLUSIONS
The population that emigrated from Wuhan was the main infection source in other cities and provinces. Some cities with a low number of cases showed a rapid increase in case load. Owing to the upcoming Spring Festival return wave, understanding the risk trends in different regions is crucial to ensure preparedness at both the individual and organization levels and to prevent new outbreaks.

Brain Tumor Research and Treatment 2019;7(1):16-24
BACKGROUND: The natural compound curcumin was known to inhibit migration and invasion of glioblastoma (GBM) cells. Fascin, a kind of actin-binding proteins, is correlated with migration and invasion of GBM cells. The purpose of this study was to investigate anti-migration and anti-invasion effects of curcumin via suppression of fascin expression in GBM cells. METHODS: U87 cell line was used as an experimental model of GBM. Fascin was quantified by Western blot analysis. And, the signal transducer and activator of transcription 3 (STAT3), known to play an important role in migration and invasion of tumor cells, were analyzed by sandwich-ELISA. Migration and invasion capacities were assessed by attachment, migration and invasion assays. Cellular morphology was demonstrated by immunofluorescence. RESULTS: At various concentrations of curcumin and exposure times, fascin expression decreased. After temporarily exposure to 10 µM/L curcumin during 6 hours as less invasive concentration and time, fascin expression temporarily decreased at 12 hours (18.4%, p=0.024), and since then recovered. And, the change of phosphrylated STAT3 level also reflected the temporarily decreased pattern of fascin expression at 12 hours (19.7%, p=0.010). Attachment, migration, and invasion capacities consistently decreased at 6, 12, and 24 hours. And, immunofluorescence showed the change of shape and the reduction of filopodia formation in cells. CONCLUSION: Curcumin is likely to suppress the fascin expression in GBM cells, and this might be a possible mechanism for anti-migration and anti-invasion effects of Curcumin via inhibition of STAT3 phosphorylation.

BACKGROUND: Emigration of health-care workers is a problem within global health systems which affects many countries, including Peru. Several factors have caused health-care workers to emigrate, including burnout syndrome (BS). This study aims to identify the association between BS and its dimensions with the intention of physicians and nurses to emigrate from Peru in 2014.

Cysticercosis, a parasitic disease caused by Taenia solium metacestode (TsM), has a major global public health impact in terms of disability-adjusted life years. The parasite preferentially infects subcutaneous tissue, but may invade the central nervous system, resulting in neurocysticercosis (NC). NC is an important neglected tropical disease and an emerging disease in industrialized countries due to immigration from endemic areas. The prevalence of taeniasis in Korea declined from 0.3%–12.7% during the 1970s to below 0.02% since the 2000s. A survey conducted from 1993 to 2006 revealed that the percentage of tested samples with high levels of specific anti-TsM antibody declined from 8.3% to 2.2%, suggesting the continuing occurrence of NC in Korea. Modern imaging modalities have substantially improved the diagnostic accuracy of NC, and recent advances in the molecular biochemical characterization of the TsM cyst fluid proteome also significantly strengthened NC serodiagnosis. Two glycoproteins of 150 and 120 kDa that induce strong antibody responses against sera from patients with active-stage NC have been elucidated. The 150 kDa protein showed hydrophobic-ligand binding activities and might be critically involved in the acquisition of host-derived lipid molecules. Fasciclin and endophilin B1, both of which play roles in the homeostatic functions of TsM, showed fairly high antibody responses against calcified NC cases. NC is now controllable and manageable. Further studies should focus on controlling late-onset intractable seizures and serological diagnosis of NC patients infected with few worms. This article briefly overviews diagnostic approaches and discusses current issues relating to NC serodiagnosis.

5.Engaging the ASEAN diaspora: Type 2 diabetes prevalence, pathophysiology, and unique risk factors among Filipino migrants in the United States.
Journal of the ASEAN Federation of Endocrine Societies 2019;34(2):126-133
Type 2 diabetes prevalence is rising rapidly in Southeast Asia (SEA) where urbanization and adoption of 'western' behavioral lifestyles are attributed as predominant risk factors. The Southeast Asian diaspora to the United States has resulted in a sizable portion of migrant and US born SEAs, with approximately 4 million Filipino Americans, 2 million Vietnamese-Americans, Cambodians (330,000), and Thai (300,000) as the most populous. Their longer exposure to a western lifestyle and participation in clinical studies with other racial/ethnic groups, provide opportunities to evaluate etiologic factors which might inform trends and intervention opportunities among residents of Southeast Asia.
Epidemiologic studies in the US have identified higher T2D prevalence among Filipinos (16.1%) compared to groups perceived to be at highest risk for T2D, namely Latinos (14.0%), Black (13.7%), and Native Americans (13.4%), while SEAs (including Burmese, Cambodian, Indonesian, Laotian, Malaysian, and Thai, 10.5%) and Vietnamese (9.9%) had higher T2D risk compared to Whites (7.7%), despite their absence of general obesity. Asian-Americans, including SEAs, East and South Asians, collectively have higher rates of undiagnosed T2D compared to other racial/ethnic groups in the US. Almost half (44%) of Filipinos with newly diagnosed T2D have isolated post-challenge hyperglycemia and will remain undiagnosed if current screening practices remain limited to measures of glycosylated hemoglobin and fasting plasma glucose.

We sought to identify the differences between adolescents left behind in their home villages/towns (LBA) and non-left behind adolescents (NLB) on subjective well-being and family functioning due to parental migration in south China. We used a stratified cluster sampling method to recruit middle school students in a city experiencing population-emigration in Jiangxi Province in 2010. Participants included adolescents from families with: (1) one migrant parent, (2) both parents who migrated, or (3) non-left behind adolescents (i.e., no migrant parent). To determine predictors of subjective well-being, we used structural equation models. Adolescents left behind by both parents (LBB) were less likely to express life satisfaction (P = 0.038) in terms of their environments (P = 0.011) compared with NLB. A parent or parents who migrated predicts lower subjective well-being of adolescents (P = 0.051) and also lower academic performance. Being apart from their parents may affect family functioning negatively from an adolescent's viewpoint. Given the hundreds of millions of persons in China, many who are parents, migrating for work, there may be mental health challenges in some of the adolescents left behind.

Obstetrics & Gynecology Science 2018;61(1):118-126
OBJECTIVE: This study aimed to analyze the association of socioeconomic factors, acculturation, and body mass index (BMI) as the first large prospective cohort study to determine the state of health of Vietnamese-born migrant women residing in Korea. METHODS: Participants were Vietnamese marriage-based immigrant women living in Korea. Data (n=1,066) was collected during both periods of baseline (2006–2011) and follow-up (2012–2014) in 34 cities in Korea. RESULTS: The results show that acculturation stress is relatively low among participants. Current BMI showed a significant difference according to the current age, monthly family income, and psychophysical stress. Depending on age, education level, monthly family income, we identified a significant difference in the annual BMI change. In correlation analysis, current BMI was significantly associated with age at arrival, reading and writing in Korean language adaptation, and psychophysical stress. Annual BMI change was significantly associated with age at arrival and years since immigration. CONCLUSION: Our analysis revealed that acculturation measured by Acculturative Stress Scale for International Students had no association with current BMI or annual BMI change, but had an association with several socioeconomic statuses. This study had the advantage that subjects had a homogenous background of marriage-based immigrant women, so we could see the association of BMI and acculturation, without considering cofounding factors.

Clinical Nutrition Research 2018;7(3):178-188
The dietary behavior of immigrants starts changing upon their arrival in a new country. We evaluated changes in dietary quality of Vietnamese women immigrants in Korea and compared dietary quality with that of Korean women. Fifty-six Vietnamese women immigrants and 56 age-matched Korean women were recruited. Dietary quality were assessed using index of nutritional quality (INQ) and diet quality index-international (DQI-I). Dietary habits were assessed according to 4 dietary behaviors: a prudent, calorie control, dietary fat control, and sodium or salt control diet. DQI-I scores of Vietnamese immigrants decreased after immigration, especially the moderation score, although the variety score increased. Scores were significantly lower than those of Korean subjects (45.1 vs. 64.5; p < 0.001). Vietnamese women immigrants had significantly poorer nutrient balance and calorie intake control, although their fat and sodium control was better than that of Korean woman (p < 0.001). INQs of protein, niacin, phosphorus, iron, zinc were lower in immigrants who had lived longer in Korea than more recent immigrants (p < 0.05). Lower INQs of protein, fiber, vitamin A, B1, B6, C, folate, and phosphorus were related to higher body fat in Vietnamese immigrants (p < 0.05). In conclusion, dietary quality of Vietnamese immigrants decreased after migration, and dietary intake was inadequate compared with that of Korean women. In addition, diet quality of Vietnamese immigrants decreased with length of residence in Korea. There was a negative correlation between diet quality and body fat percent in Vietnamese women immigrants. Findings from this study may help improve diet quality and prevent obesity in Vietnam women immigrants.

9.Beyond the Bifurcated Myth: The Medical Migration of Female Korean Nurses to West Germany in the 1970s.
Korean Journal of Medical History 2018;27(2):225-266
This study investigates beyond the bifurcated myth of the medical migration of Korean women to Germany in the 1970s, which is known as the “German dispatchment” myth from the Korean perspective and the “development aid” discourse from that of the Germans, by focusing on the newly-released documents from the German Hospital Federation (Deutsche Krankenhausgesellschaft, DKG). The migration was essentially a transfer of labor from a weak to a strong state, and the disparity of state strength characterized the nature of the recruitment mechanism. Both Korea and Germany have romanticized the labor transfer and appropriated the collective experiences of migrants for their own political purposes. In this transnational business, the Korean Overseas Development Corporation (KODCO) and the DKG maintained exclusivity in the labor migration channel and were faithful to their own interests. The DKG, as a representative of the German healthcare industry, was concerned about being criticized for destroying the healthcare system of developing countries by stealing their skilled workforce. They, therefore, tried to influence publicity in Korea and Germany to persuade the people that the recruitment benefited both countries. However, the DKG was aware of the deceitfulness of its “development aid” discourse. The Korean government, which advanced the labor export for the sake of obtaining foreign currency, romanticized it as patriotism and used the term “German dispatchment.” However, the incapacity and corruption of KODCO as an agency from the Korean perspective resulted in criticism regarding its recruitment program. The DKG complained that the selection of incapable personnel coupled with corruption was causing unforeseen financial damage to its member hospitals. Nevertheless, it officially defended its partner for the sake of its own interests, such as avoiding bad publicity and securing the sustainability of the recruitment program. The conflicts regarding nursing tasks and working conditions between Korean nurses and their German colleagues and employers captured in the documents of the DKG trace the origin of the issues in relation to cultural misunderstanding and pervasive racism. The disparity of state strength between the two countries resulted in the subaltern position of Korean female healthcare workers in the global labor market, and they tried to bring forth the best possible outcome while working in a foreign country in unfamiliar circumstances. However, the difficulties with female guest workers from Asia were generally credited to their inability to adhere to the German working style. This study contributes to the existing scholarship on this topic by filling the gaps. Historical research on the medical migration of Korean nurses and nurse-aides to West Germany has relied on limited historical sources. In 2013, the National Archives of Korea transferred official documents regarding these workers that were produced and archived by the DKG, which represented the interests of German healthcare institutions. Its documents on Korean nursing personnel provide supplementary information and display findings in different perspectives. They do not bring forth completely new findings that have never been researched before but are still valuable for delivering concrete evidence on the circumstances of that time, which were previously merely inferred.
