Reflections on fertility and postponed parenthood—interviews with highly educated women and men without children in Sweden

Background Different reasons influence the current low birth-rate and the postponement of the birth of the first child throughout Europe. The aim of this study was to explore how highly educated women and men in Sweden reflect on fertility and postponed parenthood.Methods We interviewed women (n = 22) and men (n = 18) who had started their professional careers and still had no children. Data were analysed with qualitative content analysis.Results Fertility was perceived as an unconsidered capacity, sometimes unpredictable, and different for women and men, but nevertheless taken for granted. The participants were of the opinion that fertility could be restored by assisted reproductive technologies or replaced by alternatives to a biological child. Postponed parenthood was described as an adaptation to societal changes and current discourses about parenthood as well as a consequence of a contemporary lifestyle with many competing priorities.Conclusion Highly educated young women and men in contemporary Sweden have competing priorities when planning and setting goals for their lives, and having children is one of them. They describe fertility as an imperceptible and retrievable capacity and postponed parenthood as a rational adaptation to changes in society. These findings suggest that increased information about the limitations of human reproduction is needed, but also that societal support for younger parents is of utmost importance.     

Genetics of inflammation and atopy

Multiple chromosomal regions and polymorphisms of several candidate genes have been linked to or associated with atopic diseases (hayfever, asthma, allergic eczema and rhinitis). In this mini-review, we present data demonstrating that the genetic regulation of the inflammatory response makes a major contribution to the risk of atopy. These data also suggest that the quantity (or quality) of the inflammation affects the priming phase of atopy, i.e., that induced by allergens or infectious agents in early childhood.     

Socioeconomic inequalities in lipid and glucose metabolism in early childhood in a population-based cohort: the ABCD-Study

ABSTRACT: BACKGROUND: Socioeconomic inequalities in cardiovascular disease are pervasive, yet much remains to be understood about how they originate. The objective of this study was to explore the relations of socioeconomic status to lipid and glucose metabolism as indicators of cardiovascular health in 5-6 year olds. Additionally to explore the explanatory role of maternal factors, birth outcome, and child factors. METHODS: In 1308 5-6 year old ethnic Dutch children from the ABCD cohort study, lipids (cholesterol, LDL, HDL, triglycerides), glucose and C-peptide were measured after an overnight-fast. RESULTS: There were no differences in cholesterol, HDL, LDL, and triglycerides between socioeconomic groups, as indicated by maternal education and income adequacy. However, children of low educated mothers had on average a higher glucose (beta = 0.15; 95% confidence interval (CI) 0.03 - 0.27), logC-peptide (beta = 0.07; 95% CI 0.04 - 0.09), and calculated insulin resistance (HOMA-IR) (beta = 0.15; 95% CI 0.08 - 0.22) compared to children of high educated mothers. Only childhood BMI partly explained these differences (models controlled for age, height, and sex). CONCLUSIONS: The socioeconomic gradient in cardiovascular risk factors seems to emerge in early childhood. In absence of underlying mechanisms these empirical findings are relevant for public health care and further explanatory research.     

Validating the International Classification of Functioning, Disability and Health Comprehensive Core Set for Rheumatoid Arthritis from the patient perspective: a qualitative study

OBJECTIVE: To validate the International Classification of Functioning, Disability and Health (ICF) Comprehensive Core Set for Rheumatoid Arthritis (RA) from the patient perspective. METHODS: Patients with RA were interviewed about their problems in daily functioning. Interviews were tape recorded and transcribed verbatim. Interview texts were divided into meaning units. The concepts contained in these meaning units were linked to the ICF according to 10 established linking rules. Of the transcribed data, 15% were analyzed and linked by a second health professional. The degree of agreement was calculated using the kappa statistic. RESULTS: Twenty-one patients were interviewed. Two hundred twenty different concepts contained in 367 meaning units were identified in the qualitative analysis of the interviews and linked to 109 second-level ICF categories. Of the 76 second-level categories from the ICF RA Core Set, 63 (83%) were also found in the interviews. Twenty-five second-level categories, which are not part of the current ICF RA Core Set, were identified in the interviews. The result of the kappa statistic for agreement was 0.62 (95% boot-strapped confidence interval 0.59-0.66). CONCLUSION: The validity of the ICF RA Core Set was supported by the perspective of individual patients. However, some additional issues raised in this study but not covered in the current ICF RA Core Set need to be investigated.     

Diagnosing Pouchitis

PURPOSE: Pouchitis represents a serious threat to patients with ulcerative colitis after restorative proctocolectomy with ileal pouch-anal anastomosis. The frequency of pouchitis is high, and it implies the risk of pouch failure and the risk of malignant mucosal transformation in the pouch. Early detection and precise classification of the inflammatory process are required for adequate therapy, which might be facilitated using a scoring system. The aim of the present study was to validate two existing scoring systems in routine outpatient practice. METHOD: The Heidelberg Pouchitis Activity Score and the Pouchitis Disease Activity Index developed at the Mayo Clinic were simultaneously prospectively applied in a consecutive series of 103 outpatient consultations of 41 patients at our hospital and comparatively validated against the diagnosis of pouchitis or no pouchitis concurrently made by a physician and a surgeon. RESULTS: The median score of examinations in which the clinicians diagnosis was consistent with pouchitis were significantly higher than those of examinations inconsistent with pouchitis in both scoring systems (Heidelberg Pouchitis Activity Score, 17 (interquartile range, 14–21) and 8 (interquartile range, 5–10), respectively, P < 0.001; Pouchitis Disease Activity Index, 7 (interquartile range, 5–8) and 2.5 (interquartile range, 1–4), respectively, P < 0.001). The sensitivity and specificity in the two total scores were 84 and 79.5 percent, respectively (Heidelberg Pouchitis Activity Score), and 60 and 96.2 percent, respectively (Pouchitis Disease Activity Index); in the field clinical manifestations 44 and 73.1 percent, respectively (Heidelberg Pouchitis Activity Score), and 20 and 87.2 percent, respectively (Pouchitis Disease Activity Index); in the field endoscopic manifestations 88 and 83.3 percent, respectively (Heidelberg Pouchitis Activity Score), and 60 and 89.7 percent, respectively (Pouchitis Disease Activity Index); and in the field histologic manifestations 72 and 76.9 percent, respectively (Heidelberg Pouchitis Activity Score), and 44 and 96.2 percent, respectively (Pouchitis Disease Activity Index). Lowering the cutoff point for diagnosis of pouchitis in the Pouchitis Disease Activity Index by 2 points (pouchitis: score 5) would result in an 88 percent sensitivity and a 67 percent specificity. CONCLUSIONS: Specificity and sensitivity of the Heidelberg Pouchitis Activity Score were satisfactory. The cutoff point for diagnosing pouchitis in the Pouchitis Disease Activity Index would have to be lowered to reach an acceptable sensitivity and specificity. The very poor validity of the field clinical manifestations in diagnosing pouchitis emphasizes the need for endoscopic and histologic examination for detection of pouchitis. The issue of whether the diagnosis of pouchitis should be based on endoscopic and histologic features alone, instead of additionally taking clinical features into account, should be addressed in future studies.     

Autocrine insulin-like growth factor-II stimulation of tumor cell migration is a progression step in human hepatocarcinogenesis

The protumorigenic insulin-like growth factor (IGF)-II is highly expressed in a significant fraction of human hepatocellular carcinomas (HCC). However, a functional dissection that clarifies the contribution of IGF-II-binding receptors in tumor progression and a respective molecular characterization of IGF-II signaling has not been performed. Therefore, expression of IGF-II and its receptors IGF-receptor type I (IGF-IR) and insulin receptor (IR) was efficiently blocked using small interfering RNA (siRNA) in HCC cells. Despite functional IR-signaling, oncogenic IGF-II effects such as tumor cell viability, proliferation, and anti-apoptosis were solely transmitted by IGF-IR. Although IGF-II signaling was previously not described in the context of HCC cell migration, the IGF-II-dependent expression profile displayed a high percentage of genes involved in cell motility and adhesion. Indeed, IGF-II overexpression promoted HCC cell migration, especially in synergy with hepatocyte growth factor (HGF). The therapeutic relevance of IGF-II/IGF-IR signaling was tested in vitro and in a murine xenograft transplantation model using the IGF-IR inhibitor picropodophyllin (PPP). IGF-IR inhibition by small molecule treatment efficiently reduced IGF-II-dependent signaling and all protumorigenic properties of the IGF-II/IGF-IR pathway. CONCLUSION: In human HCC cells, IGF-IR but not IR is involved in oncogenic IGF-II signaling. Autocrine stimulation of IGF-II induces HCC motility by integration of paracrine signals for full malignant competence. Thus, activation of IGF-II/IGF-IR signaling is likely a progression switch selected by function that promotes tumor cell dissemination and aggressive tumor behavior.
