- Background In workplace health promotion, a questionnaire could be of great use. Unfortunately, fatigue regarding answering questionnaires has recently become greater than before. An action research approach could be a possible way of increasing employee participation.Aim This study reports an attempt to explore key aspects for participation in, and commitment to, a workplace health promotion questionnaire process.Method The study was conducted at two wards in a Swedish hospital. Data was collected during an action research process. Data were analysed with regard to a framework of questions.Findings The three key aspects for participation in, and commitment to, a workplace health promotion questionnaire process were: an applicable questionnaire, a meaningful questionnaire process and a continuous and sustainable questionnaire process. A structure is presented as practical advice to managers, describing how such a process could be established to be applicable, meaningful and sustainable.Conclusion This study has identified key aspects and prerequisites for questionnaire processes. The prerequisites – share decision-making, involve a core group and follow a structure – are discussed and proposed for managers and workgroups to consider in further workplace health promotion questionnaire processes.Implications for nursing management The key aspects and prerequisites presented could provide a stimulating standpoint or advice, useful for planning and accomplishing workplace questionnaire processes.

- Objective: To investigate the placental gene expression of substances in the inflammatory cascade and growth factors at nine different well-defined sampling sites in full-term placentas from 12 normal weight healthy non-smoking women with an uncomplicated singleton pregnancy.Methods: All placentas (six girls and six boys) were delivered vaginally. Quantitative real-time polymerase chain reaction was used to analyze toll receptor-2 and -4, interleukin-6 and -8, tumor necrosis factor-α, leptin, ghrelin, insulin-like growth factor-1 and -2, hepatocyte growth factor, hepatocyte growth factor receptor and insulin receptor (IR).Results: The leptin gene and the IR gene showed higher expression in lateral regions near the chorionic plate compared to central regions near the basal plate (P = 0.028 and P = 0.041, respectively).Conclusion: Our results suggest that the sampling site may influence the gene expression for leptin and IR in placental tissue obtained from full-term normal pregnancies. We speculate that this may be due to differences in placental structure and perfusion and may be important when future studies are designed.

Gene expression of inflammatory markers and growth factors in placenta in relation to maternal obesity and foetal and postnatal growth
- 2020

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Maternal obesity is a growing health problem, that contributes to obstetrical complications in pregnancy, as well as neonatal morbidity and mortality. The placenta serves for gas and nutrient exchange between the mother and the foetus, and obesity may influence and modify placental growth and function. The aims of this thesis were to investigate associations between maternal obesity without associated morbidity and gene expression of inflammatory markers and growth factors in the placenta, as well as offspring birth weight and postnatal growth. Study I and III were designed as matched case-control studies including 32 obese women with an early pregnancy body mass index (BMI) ≥ 35.0 kg/m2, study II was an experimental study examining twelve placentas of normal weight women, and study IV was a cohort study including 109 obese women with a BMI ≥ 34.5 kg/m2. In studies I-IV analyses of gene expression were performed and in study III additionally cord blood concentrations were determined. No difference was found in the occurrence of placental gene expression of inflammatory markers or growth factors between obese and normal weight women, nor did the sampling site in placentas of normal weight women influence gene expression of these markers, except for leptin gene (LEP) and insulin receptor gene (INSR) expression. Ghrelin gene (GHRL) and LEP expression, as well as cord blood ghrelin and adiponectin levels, was not altered in maternal obesity, and a negatively U-shaped relationship between LEP expression and infant birth weight (BW) z-scores was observed in the placentas of obese women.In conclusion, no statistically significant difference in gene expressions of inflammatory markers and growth factors in the placenta between severely obese and normal weight women was found. These results are in contrast with earlier studies and could be due to the fact that we examined mainly healthy obese women. The correlations we found between gene expression of leptin in the placenta and the birth weight of the infants warrants further studies.

- INTRODUCTION: Leptin signaling in placentas of obese women may influence fetal growth and may be dependent on fetal sex. The aim of this study was to investigate placental gene expression of leptin, its receptor and inflammatory cytokines in obese mothers in relation to offspring birth weight and sex.METHODS: In total, 109 placental tissue samples from severely obese women (body mass index in first trimester ≥35 kg/m2) giving birth vaginally at term to a healthy child were included. Quantitative real-time PCR was used for the analysis of leptin (LEP), its receptor LEPR with two splice variants, interleukin (IL)1B, chemokine (C-X-C motif) ligand 8 (CXCL8), tumour necrosis factor (TNF), IL6, IL10, hypoxia-inducible factor 1-alpha (HIF1A) and insulin receptor (INSR). The subjects were divided into three groups based on LEP expression percentiles (<25th percentile; 25-75th percentile and >75th percentile).RESULTS: A reverse U-shaped association between LEP expression and birth weight z-scores was found (R2 = 0.075, p = 0.005). Placental LEPRb expression was downregulated (p = 0.034) in those with highest LEP expression. Female infants had higher birth weight z-scores than males (0.58 (-1.49-2.88) vs 0.21 (-1.50-2.93), p = 0.020) and their placental LEPRb expression was upregulated (p = 0.047). The associations between expression of different genes differed by sex.DISCUSSION: A reverse U-shaped relationship between placental LEP expression and offspring birth weight z-scores was found together with sexual dimorphism in LEPRb expression indicating a complex regulation of fetal growth by placental leptin signaling in maternal obesity.

- Objective: To survey the placental gene expression of inflammatory markers and growth factors in non-smoking obese women with an uncomplicated pregnancy without associated morbidity and delivery at term compared with normal weight women.Methods: Placental tissue samples from 32 obese women (body mass index, BMI >= 35.0 kg/m(2)) were compared with samples from 94 normal weight women (BMI 18.5-25.0 kg/m(2)) matched for age (+/- 1 year), gestational age (+/- 3 days), parity and mode of delivery. Semi-quantitative reverse transcription polymerase chain reaction (RT-PCR) was used to analyse toll receptor-2 and -4, interleukin-6 and -8, tumour necrosis factor-alpha, leptin, adiponectin, insulin-like growth factor-1 and -2, hepatocyte growth factor, hepatocyte growth factor receptor and insulin receptor.Results: There was no significant difference in gene expression in placental tissue samples from obese and normal weight women.Conclusion: We found no difference in the occurrence of inflammatory marker and growth factor mRNA levels in placental tissue samples from a large group of obese women without associated morbidity and with healthy infants compared to a closely matched control group of healthy normal weight women. Compared with the previous studies, this anomalous finding may be explained by the absence of associated morbidity in the obese women in our study.
