Pre-selection of individuals with epidemiological risk factors for Helicobacter pylori infection ... more Pre-selection of individuals with epidemiological risk factors for Helicobacter pylori infection and atrophic gastritis could increase the efficiency of serologic screening to prevent peptic ulcer disease and gastric cancer in Western countries. The aim of this study was to determine the prevalence of and risk factors for H. pylori infection and atrophic gastritis in a migrant community in The Netherlands. Inhabitants from an urban district in Rotterdam, The Netherlands with a large proportion of immigrants were randomly selected. Information was collected on demographic factors, socio-economic status, lifestyle, history of dyspeptic symptoms and medication use. In addition, serologic H. pylori and CagA status and the presence of atrophic gastritis were evaluated. In total, 288 subjects were included. Surinamese or Antillean, Turkish, Cape Verdian and Moroccan subjects were H. pylori-infected in 65%, 82%, 86% and 96% of cases, respectively, whereas the infection rate in Dutch subjects was 46% (all p<0.05). Within multivariate logistic regression analysis, ethnicity and number of persons in a household were identified as independent risk factors for H. pylori infection. In addition, mean pepsinogen I level and pepsinogen I/II ratio were significantly lower in subjects of non-Dutch origin as compared to Dutch subjects (both p<0.001). No Dutch subjects suffered from atrophic gastritis, as compared with 12 subjects of non-Dutch origin (p=0.13). The prevalence of H. pylori is high in migrant populations in The Netherlands. Furthermore, markers of atrophic gastritis are increased in subjects of foreign origin. Therefore, these migrant communities may constitute a target group for serologic screening to prevent H. pylori-related complications in Western countries.

Previous research has shown improved health after lifestyle improvements in SMI. In addition, we aimed to retrospectively study whether a multidisciplinary lifestyle enhancing treatment (MULTI) was associated with changes in medication use after 18 months, as compared with patients that continued treatment as usual (TAU) and explored mediation by a change in physical activity. We conducted an observational study within a cohort of inpatients with SMI, who received MULTI (N = 65) or continued TAU (N = 49). Data on their somatic and psychotropic medications were collected, converted into defined daily dose (DDD), and analyzed using linear multilevel regression, correcting for baseline value and differences between groups in age, diagnosis, and illness severity. Compared with TAU, the DDD for psychotropic medication significantly decreased with MULTI (B = −0.55, P = 0.02). Changes in total activity did not mediate this association, suggesting that multiple components of MULTI contributed. Corrected between-group analyses for subgroups of medication were not possible due to lack of power and skewed distributions. Within-group data showed a decreased proportion of users as well as median DDD in both groups for almost all medications. In addition to previously reported health improvements after 18 months of MULTI, we observed a significant decrease in dose of psychotropic medication in MULTI compared to TAU. This first study evaluating a wide range of medications indicates a possible effect of lifestyle improvements on medication use in inpatients with SMI. Findings need to be confirmed in future controlled studies, however.

Methods-Retrospective analysis of data collected between 1990 and 1993 in the national obstetric registry comprising 569 743 births. Retrospective analysis of all death certificates of 0 to 15 year old children routinely collected between 1979 and 1993, comprising 20 211 deaths. Results-Black mothers had the highest perinatal death rate compared with indigenous Dutch mothers (odds ratio 2.2). Hindustanis (West Indian Asians) had an odds ratio of 1.4 and Mediterraneans 1.3. The increased rate for black and Hindustani women could be fully explained by preterm birth. In the Mediterranean group the diVerences were explained by teenage pregnancy, grand multiparity, and socioeconomic status rather than prematurity. The death rate of Turkish and Moroccan children was twice as high as that of native Dutch children. For the diVerent diagnostic categories this was: infectious diseases, relative risk (RR) 2.2; hereditary (metabolic) disorders, RR 2.0; accidents and drowning, RR 1.9. One quarter of the Turkish and Moroccan children died while on holiday in their country of origin. Sudden infant death syndrome was twice as high for Turkish infants as for Dutch children and four times higher than for Moroccan infants. Conclusion-Ethnic minorities in the Netherlands have a higher perinatal and child mortality rate than the indigenous Dutch. Apart from socioeconomic diVerences, sociocultural and lifestyle factors play an important role.

We aimed to evaluate changes in healthcare costs 18 months after the implementation of a multidisciplinary lifestyle-enhancing treatment for inpatients with severe mental illness (MULTI) versus treatment as usual (TAU). In a cohort study (n = 114; 65 MULTI, 49 TAU), we retrospectively retrieved cost data in Euros on all patient sessions, ward stay, medication use, and hospital referrals in the quarter year at the start of MULTI (Q1 2014) and after its evaluation (Q3 2015). We used linear regression analyses correcting for baseline values and differences between groups, calculated deterministic incremental cost-effectiveness ratios for previously shown changes in physical activity, metabolic health, psychosocial functioning, and additionally quality of life, and perfo...

Anonymous data for 742 heroin-dependent people who entered methadone treatment in 1996 were extracted from a psychiatric case register. Their health service utilisation was analysed over a period of four years. Results show that ethnic minorities are under-represented in the methadone programme. They also spent fewer days in the methadone programme. No differences were found between ethnic minorities and the Dutch clients in their use of outpatient treatment. However, people of Moroccan and Turkish descent were under-represented in inpatient treatment. This is of concern because fewer days in treatment predict less than optimal treatment outcomes.

Although the prevalence of hepatitis A virus (HAV) and hepatitis B virus (HBV) infection is generally low in Western countries, pockets of higher prevalence may exist in areas with large immigrant populations. The aim of this study was to obtain further information on the prevalence of viral hepatitis in a multi-ethnic area in the Netherlands. We conducted a community-based study in a multi-ethnic neighborhood in the city of Rotterdam, the Netherlands, including both native Dutch and migrant participants, who were tested for serological markers of hepatitis A, hepatitis B, and hepatitis C infection. Markers for hepatitis A infection were present in 68% of participants. The prevalence of hepatitis B core antibodies (anti-HBc), a marker for previous or current infection, was 20% (58/284). Prevalence of hepatitis A and B varied by age group and ethnicity. Two respondents (0.7%) had chronic HBV infection. The prevalence of hepatitis C ...
