Changing trends in caesarean section births in Murmansk County, Russia
Objective: To analyze changing trends of caesarean section (CS) birth rates in Murmansk County, Russia over a 5- year period (2006-2010) using the Robson 10-group classification system. Design: A registry- based study. Setting: The Murmansk County Birth Registry (MCBR). Study population: All deliveries registered (N=44 267) in the MCBR between 1st of January 2006 and 31st of December 2010. Methods: The study population comprises of data from the MCBR and selected perinatal health indicators designed by the Euro-Peristat. The Robson 10- group was applied to categorize all women into 8-modified groups by combining all nulliparous (Groups 1 and 2) and all multiparous (Groups 3 and 4) women with single cephalic pregnancies at ≥ 37 weeks of gestation. The CS rates were examined and described for each group, to identify the most important contributors to CS rates in this population. Results: Maternal age, parity, maternal smoking, education, body mass index, birth weight changed significantly from 2006 to 2010, except gestational age and multiple births. There was an increase in the overall CS proportion from 17.4% to 22.5% in Murmansk County between 2006 and 2010. Nulliparous women (Groups 1 and 2) and women with previous CS (Group 5), with single cephalic pregnancies at ≥ 37 gestational weeks were the greatest contributors at 39% and 31%, respectively, to the overall increase of CS rate from 2006 to 2010. Conclusion: The observed increase in CS rate is mainly attributed to the increase of CS rate in Groups 1 and 2 (first-time CS), followed by Group 5 (repeated CS).

Prognostic Impacts of Angiopoietins in NSCLC Tumor Cells and Stroma : VEGF-A Impact Is Strongly Associated with Ang-2 Andersen, Sigve; Dønnem, Tom; Al-Shibli, Khalid Ibrahim; Al-Saad, Samer; Stenvold, Helge; Busund, Lill-Tove; Bremnes, Roy M. (Journal article; Tidsskriftartikkel; Peer reviewed, 2011)Angiopoietins and their receptor Tie-2 are, in concert with VEGF-A, key mediators in angiogenesis. This study evaluates the prognostic impact of all known human angiopoietins (Ang-1, Ang-2 and Ang-4) and their receptor Tie-2, as well as their relation to the prognostic expression of VEGF-A. 335 unselected stage I-IIIA NSCLC-patients were included and tissue samples of respective tumor cells and ...
The Temporomandibular Joint in Juvenile Idiopathic Arthritis, focusing on Quality of Life, Oral Microbiome and Intervention Frid, Paula (Doctoral thesis; Doktorgradsavhandling, 2020-10-02)The temporomandibular joint (TMJ) is commonly involved in juvenile idiopathic arthritis (JIA), and may lead to impaired mouth opening, pain and facial growth disturbances. Asymptomatic TMJ arthritis may be diagnosed late in the disease course, thus management is challenging. The overall objectives of this thesis were to provide new knowledge on quality of life (QoL), the oral microbiome and interventions ...
Humant papillomavirus : en litteraturstudie om HPV, dets relasjon til cancer og tiltak mot videre spredning av virus Gabrielsen, Endre (Master thesis; Mastergradsoppgave, 2012-06-01)I 1983 oppdaget zur Hausen sammenhengen mellom Humant Papillomavirus (HPV) og livmorhalskreft. På denne tiden visste man ikke at det var HPV som var årsaken til at Helaceller kunne leve in vitro. Ny forskning relaterer HPV til en rekke andre cancertyper. En stor andel anal-, oropharyngeal-, penis-, vaginal-, og vulvacancer skyldes HPV. Det er også påvist HPV i tumorvev fra øsofagus, larynx, lunge, ...
