- BACKGROUND: Human papillomavirus types 16 (HPV-16) and 18 (HPV-18) cause approximately 70% of cervical cancers worldwide. A phase 3 trial was conducted to evaluate a quadrivalent vaccine against HPV types 6, 11, 16, and 18 (HPV-6/11/16/18) for the prevention of high-grade cervical lesions associated with HPV-16 and HPV-18. METHODS: In this randomized, double-blind trial, we assigned 12,167 women between the ages of 15 and 26 years to receive three doses of either HPV-6/11/16/18 vaccine or placebo, administered at day 1, month 2, and month 6. The primary analysis was performed for a per-protocol susceptible population that included 5305 women in the vaccine group and 5260 in the placebo group who had no virologic evidence of infection with HPV-16 or HPV-18 through 1 month after the third dose (month 7). The primary composite end point was cervical intraepithelial neoplasia grade 2 or 3, adenocarcinoma in situ, or cervical cancer related to HPV-16 or HPV-18. RESULTS: Subjects were followed for an average of 3 years after receiving the first dose of vaccine or placebo. Vaccine efficacy for the prevention of the primary composite end point was 98% (95.89% confidence interval [CI], 86 to 100) in the per-protocol susceptible population and 44% (95% CI, 26 to 58) in an intention-to-treat population of all women who had undergone randomization (those with or without previous infection). The estimated vaccine efficacy against all high-grade cervical lesions, regardless of causal HPV type, in this intention-to-treat population was 17% (95% CI, 1 to 31). CONCLUSIONS: In young women who had not been previously infected with HPV-16 or HPV-18, those in the vaccine group had a significantly lower occurrence of high-grade cervical intraepithelial neoplasia related to HPV-16 or HPV-18 than did those in the placebo group.

- We examined the association between sports and other leisure-time physical activities during pregnancy and birth weight of babies born after 37 completed weeks of gestation. All Danish-speaking pregnant women attending routine antenatal care at the Department of Obstetrics, Aarhus University Hospital, Denmark, from August 1989 to September 1991 were invited to participate in the study. A total of 4458 healthy women who delivered after 37 completed gestational weeks participated in this study. The associations between sports (0, 1-2, 3+ h/week) or leisure-time physical activity (sedentary, light, and moderate to heavy) and birth weight were examined by linear and logistic regression and adjusted for potential confounding factors such as smoking, parity, schooling, pre-pregnancy body mass index and gestational age. The results showed that pregnant women who practiced sports or were moderate to heavy leisure-time physical active during the early second or the early third trimester gave birth to infants with a similar birth weight as inactive women. The proportion of newborns with a low (<2500 g) or a high birth weight (>/=4500 g) was also unchanged. In conclusion, in this large population-based study, we found no association between sports and leisure-time physical activity and low-birth weight, high-birth weight, or average-birth weight.

- In order to investigate the association between leisure time physical activity in the year before pregnancy and pre-eclampsia, stratifying for maternal BMI, a prospective study was carried out from 1996 to 1998. Pregnant women attending their first antenatal care visit, were invited to participate in the study. Inclusion criteria: Danish-speaking, > OR =18 years of age, gestational age <22 weeks, no psychiatric disease, or abuse. The participants (n = 2,793) self-filled a questionnaire at 12-18 gestational weeks. Leisure time physical activity was categorised as sedentary, light and moderate-to-heavy. The results showed that pre-eclampsia occurred in 4.2%, 4.2% and 3.1% of women with sedentary, light and moderate-to-heavy leisure time physical activity, respectively. Although we found a tendency towards a lower risk of pre-eclampsia in women with the highest degree of physical activity during leisure time, especially in overweight women, no significant associations were found. It was concluded that leisure time physical activity the year before pregnancy does not protect against pre-eclampsia.

- We examined background information and course of labour from a cohort of 2,810 low-risk nulliparas to identify possible lifestyle and anthropometrical risk indicators for dystocia. Criteria for dystocia: cervical dilatation <2 cm over 4 h during labour's active phase, or no descent during 2 h (3 h with epidural) in the descending phase, or no progress for 1 h during the expulsive phase. After adjustments, athletics or heavy gardening >= 4 h per week appeared protective for dystocia (OR 0.63, CI 0.45-0.89), contrary to a non-significant finding of intensive physical training (OR 1.57, CI 0.84-2.93). Caffeine intake of 200-299 mg/day was associated with dystocia (OR 1.37, CI 1.04-1.80); also high maternal age (OR 2.25, CI 1.58-3.22), small stature (OR 2.18, CI 1.51-3.15) and pre-pregnancy overweight (OR 1.28, CI 1.02-1.61). No association was found between dystocia and alcohol intake, smoking, night sleep and options for resting during the day.

- BACKGROUND: Secretoneurin (SN) levels are increased in patients with heart failure (HF), but whether SN provides prognostic information and influences cardiomyocyte function is unknown.OBJECTIVES: This study sought to evaluate the merit of SN as a cardiovascular biomarker and assess effects of SN on cardiomyocyte Ca(2+) handling.METHODS: We assessed the association between circulating SN levels and mortality in 2 patient cohorts and the functional properties of SN in experimental models.RESULTS: In 143 patients hospitalized for acute HF, SN levels were closely associated with mortality (n = 66) during follow-up (median 776 days; hazard ratio [lnSN]: 4.63; 95% confidence interval: 1.93 to 11.11; p = 0.001 in multivariate analysis). SN reclassified patients to their correct risk strata on top of other predictors of mortality. In 155 patients with ventricular arrhythmia-induced cardiac arrest, SN levels were also associated with short-term mortality (n = 51; hazard ratio [lnSN]: 3.33; 95% confidence interval: 1.83 to 6.05; p < 0.001 in multivariate analysis). Perfusing hearts with SN yielded markedly increased myocardial levels and SN internalized into cardiomyocytes by endocytosis. Intracellularly, SN reduced Ca(2+)/calmodulin (CaM)-dependent protein kinase II δ (CaMKIIδ) activity via direct SN-CaM and SN-CaMKII binding and attenuated CaMKIIδ-dependent phosphorylation of the ryanodine receptor. SN also reduced sarcoplasmic reticulum Ca(2+) leak, augmented sarcoplasmic reticulum Ca(2+) content, increased the magnitude and kinetics of cardiomyocyte Ca(2+) transients and contractions, and attenuated Ca(2+) sparks and waves in HF cardiomyocytes.CONCLUSIONS: SN provided incremental prognostic information to established risk indices in acute HF and ventricular arrhythmia-induced cardiac arrest.

Carcinoma in situ of the breast: correlation of histopathology to immunohistochemical markers and DNA ploidy

Tidskriftsartikel (refereegranskat)abstract
- In a consecutive and unselected series of 178 cases of carcinoma in situ of the breast (CIS), comprising both ductal (DCIS) and lobular type (LCIS), and a series of 48 cases of invasive carcinoma (IC) with predominance of DCIS, the association between histopathology, immunohistochemical markers (ER, PgR, MIB-1, c-erbB-2, and p53), and DNA ploidy was investigated, in order to discriminate biologically different groups. In DCIS, significant correlation was shown between large nuclear size and comedonecrosis, both of which showed also strong association to DNA aneuploidy, high proliferation activity, low steroid receptor content, and overexpression of c-erbB-2 and p53 factors that may indicate an aggressive behavior. Small nuclear CIS, whether LCIS or DCIS, on the contrary, were DNA diploid with low proliferation, and no cases showed overexpression of c-erbB-2 and p53. Heterogeneity with respect to the investigated parameters was also a frequent finding that may reflect a development complexity. In IC, comparison of the DCIS and the invasive component showed similar patterns. No significant differences were shown between DCIS without and with invasion. This may indicate that none of the investigated parameters on its own are essential for the event of invasion.
