Clinical presentation and diagnostic sensitivity of laboratory tests for Strongyloides stercoralis in travellers compared with immigrants in a non-endemic country

OBJECTIVES: To assess whether the clinical and laboratory methods for diagnosing Strongyloides stercoralis infection in non-endemic countries is different between those who are chronically exposed and those who travel. METHODS: Analysis of laboratory and clinical data from 204 patients having S. stercoralis infection at the Hospital for Tropical Diseases, London. RESULTS: Sixty-four travellers and 128 immigrants from endemic countries had laboratory-proven strongyloides. In those with microscopically proven disease, serology was 73% sensitive in travellers and 98% sensitive in immigrants (P < 0.001). There was no difference in the eosinophil count between the two groups with 19% having a normal count. Patterns of symptoms varied between the groups, and around one-third were asymptomatic in both groups. Serology was of limited use in follow-up. CONCLUSIONS: Eosinophil count and stool microscopy are insufficiently sensitive to be used alone for screening strongyloides. The sensitivity of serology is good in immigrants with chronic infection, but lower in travellers.     

Prevalence of Antibodies to Hepatitis E Virus in Immigrants: A Seroepidemiological Survey in the District of Foggia (Apulia‐Southern Italy)

Hepatitis E virus (HEV) is the etiologic agent of endemically transmitted viral hepatitis. HEV is endemic in developing countries where it occurs in sporadic and endemic forms, but autochthonous sporadic cases of hepatitis E have been reported in North America and in Europe, including Italy. The aim of the present study was to assess the seroprevalence of antibodies to HEV in immigrants from developing countries to the province of Foggia. The seroprevalence of HEV was determined in a cohort of 412 immigrants (mostly from countries in sub‐Saharan Africa) who had arrived recently in Italy. Serum samples were tested for anti‐HEV by a commercial enzyme immunoassay (EIA) based on recombinant proteins; positive results were confirmed by a Western blot assay (Recomblot HEV). A total of 88 (21.3%) of the 412 serum samples examined were reactive to IgG anti‐HEV. Eighty‐one of these samples (19.7%) were confirmed by Western blot. Anti‐HEV IgM was found in 34/81 subjects (41.9%) of the anti‐HEV IgG positive serum samples. Almost all anti‐HEV positive subjects were asymptomatic clinically, but alanine aminotransferase serum values were elevated in 28/34 (82.3%) patients with IgM anti‐HEV‐positive. The results of this study indicate high circulation of HEV in the immigrant population. The high prevalence of acute hepatitis involved mainly subjects who arrived in Italy during the same period from the same countries (Eritrea, Ethiopia, and Somalia). J. Med.

The impact of social capital on depression among older Chinese and Korean immigrants: similarities and differences

Objectives: The objective of this study is to examine similarities and differences in terms of the influence of social capital on depression among older Chinese and Korean immigrants.

Methods: The study used data collected from both 172 Chinese and 210 Korean immigrants living in Los Angeles County. The variables included depression Geriatric Depression Scale-Short Form, (GDS-SF), social capital (five indices of norms, trust, partnership in community, information sharing, and political participation), and demographics.

Results: The study found that partnership in community was significantly associated with a lower level of depression for both the groups. On the other hand, political participation was only associated with a lower level of depression for older Chinese immigrants. Also, norms and information sharing were only associated with a lower level of depression for older Korean immigrants.

Conclusion: There was an evidence for the correlation between social capital and depression in older Chinese and Korean immigrant population. It suggests the needs to develop social programs and service in order to build more social capital for older immigrants.     

Skandinavisk Selskab for Psykofarmakologi: höll sitt 19:e årsmöte den 30 och 31 mars 1978 på Hotel Scandinavia i Köpenhamn

Background: Today 29.3% of all newborns in Sweden are second-generation immigrants. Studies on mental health among these children are few, inconclusive and vary widely with regard to the informant used and the age of the immigrant. The majority of previous studies focus on study groups that cover a wide age span but since mental health varies considerably during the preadolescent and adolescent years, more age-specific studies are needed. Additional focus on the health and well-being of these children is necessary if a well-functioning society is to develop. Aim: To investigate whether and how second-generation immigrant children in Sweden differ from non-immigrant children in their presentation of self-reported mental health at the age of 12. Methods: Second-generation immigrant children (n = 142) from a birth cohort in southern Sweden, subjects of the SESBiC-study (the South East Sweden Birth Cohort-study) were compared with non-immigrant children (n = 1036) from the same cohort in their presentation of self-reported mental health at the age of 12 using the Strengths and Difficulties Questionnaire. Gender, family structure and parents’ educational level were controlled for. Results: Second-generation immigrant children did not differ from the non-immigrant children in their own presentation of mental health at the age of 12 in any of the categories of immigrant groups. Conclusion: It is a promising sign for future integration that second-generation immigrant children's self-reported mental health at the age of 12 was quite similar to that of non-immigrant children.     

Out of sight but not out of mind: Home countries' macroeconomic volatilities and immigrants' mental health

We provide the first empirical evidence that better economic performances by immigrants' countries of origin, as measured by lower consumer price index (CPI) or higher gross domestic product, improve immigrants' mental health. We use an econometrically‐robust approach that exploits exogenous changes in macroeconomic conditions across immigrants' home countries over time and controls for immigrants' observable and unobservable characteristics. The CPI effect is statistically significant and sizeable. Furthermore, the CPI effect diminishes as the time since emigrating increases. By contrast, home countries' unemployment rates and exchange rate fluctuations have no impact on immigrants' mental health.     

Psychiatric nursing care experiences of immigrant patients: A Focused ethnographic study

This study aimed to describe the psychiatric nursing care experiences of immigrant patients. The incidence of mental health problems is higher and the use of mental health services is lower among immigrants, especially refugees, compared with the majority of the population. The study uses a qualitative research approach, with an emphasis on focused ethnography research methods. The participants were immigrant patients (N = 14) residing in adult psychiatric wards of certain hospitals (N = 3) selected for the study. A majority of the participants were refugees or asylum seekers. A total of 21 in‐depth interviews were conducted. The experiences of these immigrant patients, both in their home countries and in their country of residence, had had an adverse effect on their mental health, with past traumatic experiences being the most central factor. Their symptoms included depression, anxiety, somatization, and psychosis. The findings show that the categories of factors that helped promote recovery among immigrant patients were nursing, medical treatment, care environment, and the patients' own methods. Based on the findings, a systematic evaluation of traumatic experiences is recommended for immigrants from countries with a history of war and/or political violence. Healthcare providers should also consider the importance of cultural desire in psychiatric nursing for the recovery of patients.
