Globale Gesundheit

Durch die Globalisierung werden wir zunehmend mit Problemen konfrontiert, welche Landesgrenzen überschreiten. Auch viele gesundheitspolitische Entscheidungen werden heute auf europäischer Ebene oder unter der Mitarbeit internationaler Organisationen getroffen. In diesem Kapitel betrachten wir Gesundheitsindikatoren sowie Krankheits- und Todesursachen im Hinblick auf das Bevölkerungseinkommen und die Entwicklung in verschiedenen Ländern. Wir analysieren die wichtigsten Faktoren, die die Gesundheit der Menschen in Industrie- und Entwicklungsländern beeinflussen und beschäftigen uns schließlich mit den Strategien und Akteuren, welche die Globale Gesundheit heute prägen.

Adolescent survivors of childhood cancer: are they vulnerable for psychological distress?

OBJECTIVES: We aimed to (i) evaluate psychological distress in adolescent survivors of childhood cancer and compare them to siblings and a norm population; (ii) compare the severity of distress of distressed survivors and siblings with that of psychotherapy patients; and (iii) determine risk factors for psychological distress in survivors. METHODS: We sent a questionnaire to all childhood cancer survivors aged <16 years when diagnosed, who had survived ≥5 years and were aged 16-19 years at the time of study. Our control groups were same-aged siblings, a norm population, and psychotherapy patients. Psychological distress was measured with the Brief Symptom Inventory-18 (BSI-18) assessing somatization, depression, anxiety, and a global severity index (GSI). Participants with a T-score ≥57 were defined as distressed. We used logistic regression to determine risk factors. RESULTS: We evaluated the BSI-18 in 407 survivors and 102 siblings. Fifty-two survivors (13%) and 11 siblings (11%) had scores above the distress threshold (T ≥ 57). Distressed survivors scored significantly higher in somatization (p = 0.027) and GSI (p = 0.016) than distressed siblings, and also scored higher in somatization (p ≤ 0.001) and anxiety (p = 0.002) than psychotherapy patients. In the multivariable regression, psychological distress was associated with female sex, self-reported late effects, and low perceived parental support. CONCLUSIONS: The majority of survivors did not report psychological distress. However, the severity of distress of distressed survivors exceeded that of distressed siblings and psychotherapy patients. Systematic psychological follow-up can help to identify survivors at risk and support them during the challenging period of adolescence. Copyright © 2013 John Wiley & Sons, Ltd.

Malnutrition in pediatric patients with cancer at diagnosis and throughout therapy: A multicenter cohort study

Malnutrition is a common problem in pediatric patients with cancer. Reported prevalence varies widely and has often been assessed only in a subset of childhood types of cancer. This study aimed to describe the prevalence of malnutrition among pediatric patients newly diagnosed with cancer, to describe the occurrence and course of malnutrition during therapy and to identify factors associated with malnutrition during therapy.

A prospective study of the impact of air pollution on respiratory symptoms and infections in infants

Rationale: There is increasing evidence that short-term exposure to air pollution has a detrimental effect on respiratory health, but data from healthy populations, particularly infants, are scarce. Objectives: To assess the association of air pollution with frequency and severity of respiratory symptoms and infections measured weekly in healthy infants. Methods: In a prospective birth cohort of 366 infants of unselected mothers, respiratory health was assessed weekly by telephone interviews during the first year of life (19,106 total observations). Daily mean levels of particulate matter (PM10), nitrogen dioxide (NO2), and ozone (O3) were obtained from local monitoring stations. We determined the association of the preceding week's pollutant levels with symptom scores and respiratory tract infections using a generalized additive mixed model with an autoregressive component. In addition, we assessed whether neonatal lung function influences this association and whether duration of infectious episodes differed between weeks with normal PM10 and weeks with elevated levels. Measurements and Main Results: We found a significant association between air pollution and respiratory symptoms, particularly in the week after respiratory tract infections (risk ratio, 1.13 [1.02-1.24] per 10 μg/m(3) PM10 levels) and in infants with premorbid lung function. During times of elevated PM10 (>33.3 μg/m(3)), duration of respiratory tract infections increased by 20% (95% confidence interval, 2-42%). Conclusions: Exposure to even moderate levels of air pollution was associated with increased respiratory symptoms in healthy infants. Particularly in infants with premorbid lung function and inflammation, air pollution contributed to longer duration of infectious episodes with a potentially large socioeconomic impact.

Newborn screening for cystic fibrosis in Switzerland - Consequences after analysis of a 4 months pilot study

BACKGROUND: Switzerland introduced newborn screening (NBS) for CF in 2011, using an IRT/DNA/IRT protocol. This paper describes the results of the first year and compares two versions of the protocol with different IRT cut-offs, particularly effects on recall rate, sensitivity and specificity. METHODS: IRT cut-offs were >45ng/ml (99.0th percentile) in period 1 (months 1-4) and >50ng/ml (99.2nd percentile) in period 2 (months 5-12). In period 2 we abstained from recalls when none of the 7 most common CF mutations were detected and IRT was <60ng/ml. RESULTS: In periods 1 and 2, 26,535 and 56,663 tests were performed. Recall rates were 0.94% and 0.48%, respectively (p<0.001), PPV increased from 23% to 47% (p=0.024) and sensitivity was 90% and 100%. CONCLUSIONS: Raising initial IRT cut-off from the 99.0th to the 99.2nd percentile and abstaining from recalls for children with an IRT<60ng/ml and carrying no major CFTR mutation significantly reduced the recall rate without affecting sensitivity.
