- OBJECTIVE: This study aimed to explore the value of individualized feedback on performance, flow and self-efficacy during simulated laparoscopy. Furthermore, we wished to explore attitudes towards feedback and simulator training among medical students.METHODS: Sixteen medical students were included in the study and randomized to laparoscopic simulator training with or without feedback. A teacher provided individualized feedback continuously throughout the procedures to the target group. Validated questionnaires and scales were used to evaluate self-efficacy and flow. The Mann-Whitney U test was used to evaluate differences between groups regarding laparoscopic performance (instrument path length), self-efficacy and flow. Qualitative data was collected by group interviews and interpreted using inductive thematic analyses.RESULTS: Sixteen students completed the simulator training and questionnaires. Instrument path length was shorter in the feedback group (median 3.9 m; IQR: 3.3-4.9) as compared to the control group (median 5.9 m; IQR: 5.0-8.1), p<0.05. Self-efficacy improved in both groups. Eleven students participated in the focus interviews. Participants in the control group expressed that they had fun, whereas participants in the feedback group were more concentrated on the task and also more anxious. Both groups had high ambitions to succeed and also expressed the importance of getting feedback. The authenticity of the training scenario was important for the learning process.CONCLUSIONS: This study highlights the importance of individualized feedback during simulated laparoscopy training. The next step is to further optimize feedback and to transfer standardized and individualized feedback from the simulated setting to the operating room.

- Introduction: Severe obstetric complications increase with the number of previous cesarean deliveries. In the Nordic countries most women have two children. We present the risk of severe obstetric complications at the delivery following a first elective or emergency cesarean and the risk by intended mode of second delivery. Material and methods: A two-year population-based data collection of severe maternal complications in women with two deliveries in the Nordic countries (n = 213 518). Denominators were retrieved from the national medical birth registers. Results: Of 35 450 first cesarean deliveries (17%), 75% were emergency and 25% elective. Severe complications at second delivery were more frequent in women with a first cesarean than with a first vaginal delivery, and rates of abnormally invasive placenta, uterine rupture and severe postpartum hemorrhage were higher after a first elective than after a first emergency cesarean delivery [relative risk (RR) 4.1, 95% confidence intervals (CI) 2.0-8.1; RR 1.8, 95% CI 1.3-2.5; RR 2.3, 95% CI 1.5-3.5, respectively]. A first cesarean was associated with up to 97% of severe complications in the second pregnancy. Induction of labor was associated with an increased risk of uterine rupture and severe hemorrhage. Conclusion: Elective repeat cesarean can prevent complete uterine rupture at the second delivery, whereas the risk of severe obstetric hemorrhage, abnormally invasive placenta and peripartum hysterectomy is unchanged by the intended mode of second delivery in women with a first cesarean. Women with a first elective vs. an emergency cesarean have an increased risk of severe complications in the second pregnancy.

- Objective: To assess the rates and characteristics of women with complete uterine rupture, abnormally invasive placenta, peripartum hysterectomy, and severe blood loss at delivery in the Nordic countries. Design: Prospective, Nordic collaboration. Setting: The Nordic Obstetric Surveillance Study (NOSS) collected cases of severe obstetric complications in the Nordic countries from April 2009 to August 2012. Sample and methods: Cases were reported by clinicians at the Nordic maternity units and retrieved from medical birth registers, hospital discharge registers, and transfusion databases by using International Classification of Diseases, 10th revision codes on diagnoses and the Nordic Medico-Statistical Committee Classification of Surgical Procedure codes. Main outcome measures: Rates of the studied complications and possible risk factors among parturients in the Nordic countries. Results: The studied complications were reported in 1019 instances among 605362 deliveries during the study period. The reported rate of severe blood loss at delivery was 11.6/10000 deliveries, complete uterine rupture was 5.6/10000 deliveries, abnormally invasive placenta was 4.6/10000 deliveries, and peripartum hysterectomy was 3.5/10000 deliveries. Of the women, 25% had two or more complications. Women with complications were more often >35years old, overweight, with a higher parity, and a history of cesarean delivery compared with the total population. Conclusion: The studied obstetric complications are rare. Uniform definitions and valid reporting are essential for international comparisons. The main risk factors include previous cesarean section. The detailed information collected in the NOSS database provides a basis for epidemiologic studies, audits, and educational activities.

- Introduction.Reliability in visual cardiotocography interpretation isunsatisfying, which has led to the development of computerizedcardiotocography. Computerized analysis is well established for antenatal fetalsurveillance but has yet not performed sufficiently during labor. We aimed toinvestigate the capacity of a new computerized algorithm compared with visualassessment in identifying intrapartum fetal heart rate baseline anddecelerations.Material and methods.In all, 312 intrapartum cardiotocographytracings with variable decelerations were analyzed by the computerizedalgorithm and visually examined by two observers, blinded to each other andthe computer analysis. The width, depth and area of each deceleration wasmeasured. Four cases (>100 variable decelerations) were subjected to in-depthdetailed analysis. The outcome measures were bias in seconds (width), beatsper minute (depth), and beats (area) between computer and observers usingBland–Altman analysis. Interobserver reliability was determined by calculatingintraclass correlation and Spearman rank analysis.Results.The analysis (312cases) showed excellent intraclass correlation (0.89–0.95) and very strongSpearman correlation (0.82–0.91). The detailed analysis of>100 decelerationsin four cases revealed low bias between the computer and the two observers;width 1.4 and 1.4 seconds, depth 5.1 and 0.7 beats per minute, and area 0.1and–1.7 beats. This was comparable to the bias between the two observers:0.3 seconds (width), 4.4 beats per minute (depth) and 1.7 beats (area). Theintraclass correlation was excellent (0.90–.98).Conclusion.A novelcomputerized algorithm for intrapartum cardiotocography analysis is asaccurate as gold standard visual assessment, with high correlation and low bias.

- Objective: To assess the prevalence and risk factors of emergency peripartum hysterectomy. Design:Nordic collaborative study. Population605362 deliveries across the five Nordic countries. Methods: We collected data prospectively from patients undergoing emergency peripartum hysterectomy within 7days of delivery from medical birth registers and hospital discharge registers. Control populations consisted of all other women delivering on the same units during the same time period. Main outcome measures: Emergency peripartum hysterectomy rate. Results: The total number of emergency peripartum hysterectomies reached 211, yielding an incidence rate of 3.5/10000 (95% confidence interval 3.0-4.0) births. Finland had the highest prevalence (5.1) and Norway the lowest (2.9). Primary indications included an abnormally invasive placenta (n=91, 43.1%), atonic bleeding (n=69, 32.7%), uterine rupture (n=31, 14.7%), other bleeding disorders (n=12, 5.7%), and other indications (n=8, 3.8%). The delivery mode was cesarean section in nearly 80% of cases. Previous cesarean section was reported in 45% of women. Both preterm and post-term birth increased the risk for emergency peripartum hysterectomy. The number of stillbirths was substantially high (70/1000), but the case fatality rate stood at 0.47% (one death, maternal mortality rate 0.17/100000 deliveries). Conclusions: A combination of prospective data collected from clinicians and information gathered from register-based databases can yield valuable data, improving the registration accuracy for rare, near-miss cases. However, proper and uniform clinical guidelines for the use of well-defined international diagnostic codes are still needed.

- The Nordic medical birth registers have long been used for valuable clinical research. Their collection of data for more than four decades offers unusual possibilities for research across generations. At the same time, serum and blotting paper blood samples have been stored from most neonates. Two large cohorts (approximately 100000 births) in Denmark and Norway have been described by questionnaires, interviews and collection of biological samples (blood, urine and milk teeth), as well as a systematic prospective follow-up of the offspring. National patient registers provide information on preceding, underlying and present health problems of the parents and their offspring. Researchers may, with permission from the national authorities, obtain access to individualized or anonymized data from the registers and tissue-banks. These data allow for multivariate analyses but their usefulness depends on knowledge of the specific registers and biological sample banks and on proper validation of the registers.

- Background: Long-term results after obstetric anal sphincter injury (OASI) are poor. We aimed to improve the long-term outcome after OASI by lessening symptoms of anal incontinence. Methods: In a prospective study at Malmo University Hospital, twenty-six women with at least grade 3B OASI were classified and sutured in a systematic way, including separate suturing of the internal and external sphincter muscles with monofilament absorbable sutures. The principal outcome assessed by answers given to six questions, was a difference in anal incontinence score, between the study group and two control groups (women with prior OASI [n = 180] and primiparous women delivered vaginally without a diagnose of OASI [n = 100]). Results: An anal incontinence score of zero (i.e., no symptoms) was found in 74% of the study group, 47% of the OASI control group, and 66% of the vaginal control group (p = 0.02 and 0.5, as compared to the study group). Conclusions: A modified suturing technique was followed by significant improved one-year symptoms of anal incontinence as compared to historical cases.

- Aim An inverse relationship exists between vitamin D levels and diabetes mellitus However, little is known about the correlation of sun exposure habits and type 2 diabetes mellitus (DM) Methods A South Swedish cohort study comprising 1000 women from each age group between 25 and 64 (n = 40,000) drawn from the Southern Swedish population registry 1990-1992 At the inception of the study 74% answered the inquiry (n = 29,518) and provided detailed information on their sun exposure habits and other variables A follow-up inquiry was sent 2000-2002 which 24,098 women answered The mean follow-up time was 11 years Logistic regression analysis was used and the main outcome was the relationship between type 2 DM and sun exposure habits. Results Our findings indicated that women with active sun exposure habits were at a 30% lower risk of having DM, as compared to those with non-active habits. There was an inverse relation between this risk reduction and BMI Conclusion Our investigation gives possible epidemiological explanation to ethnic and seasonal differences in type 2 DM and metabolic control The study supports that sunlight is involved in the glucose metabolism (C) 2010 Elsevier Ireland Ltd All rights reserved.
