Background and Objectives: This paper reports on historical changes in assessment culminating in the experience of one discipline with negotiated student feedback that has helped design and modify assessment to cater for the requirements of both students and teachers. The standard of assessment required to pass Obstetrics and Gynaecology in the four year graduate entry program in the School of Medicine at The University of Queensland, Brisbane, Australia has become less formalised and more collaborative. Changes in assessment in this discipline over the last 20 years reflect the development of an understanding of the educational principles associated with adult teaching and learning. Assessment has evolved from being teacher focussed, with questionable reliability, validity, and emphasis on outcomes, to being focussed on learning and the student. Multiplechoice examinations, combined with a collaborative approach to the reliability and validity of questions and answers and a debrief or feedback session have been found to provide an assessment format that is art acceptable measure oflearning for both teachers and students. Changes in assessment reflect a collaborative process between teachers and students based on principles of adult learning and involving negotiated student feedback. Our experience with this form of negotiated outcome for assessment is presented together with suggestions for improvement and is contrasted with assessment methods used in this department over the last 20 years. Change and refinement will continue as medical programs strive to meet the learning needs of students and assessment outcomes that are acceptable to its teachers.

To detect the presence of male DNA in vaginal samples collected from survivors of sexual violence and stored on filter paper. A pilot study was conducted to evaluate 10 vaginal samples spotted on sterile filter paper: 6 collected at random in April 2009 and 4 in October 2010. Time between sexual assault and sample collection was 4-48hours. After drying at room temperature, the samples were placed in a sterile envelope and stored for 2-3years until processing. DNA extraction was confirmed by polymerase chain reaction for human β-globin, and the presence of prostate-specific antigen (PSA) was quantified. The presence of the Y chromosome was detected using primers for sequences in the TSPY (Y7/Y8 and DYS14) and SRY genes. β-Globin was detected in all 10 samples, while 2 samples were positive for PSA. Half of the samples amplified the Y7/Y8 and DYS14 sequences of the TSPY gene and 30% amplified the SRY gene sequence of the Y chromosome. Four male samples and 1 female sample served as controls. Filter-paper spots stored for periods of up to 3years proved adequate for preserving genetic material from vaginal samples collected following sexual violence.

The vast majority of maternal deaths in low-and middle-income countries are preventable. Delay in obtaining access to appropriate health care is a fairly common problem which can be improved. The objective of this study was to explore the association between delay in providing obstetric health care and severe maternal morbidity/death. This was a multicentre cross-sectional study, involving 27 referral obstetric facilities in all Brazilian regions between 2009 and 2010. All women admitted to the hospital with a pregnancy-related cause were screened, searching for potentially life-threatening conditions (PLTC), maternal death (MD) and maternal near-miss (MNM) cases, according to the WHO criteria. Data on delays were collected by medical chart review and interview with the medical staff. The prevalence of the three different types of delays was estimated according to the level of care and outcome of the complication. For factors associated with any delay, the PR and 95%CI controlled for cluster design were estimated. A total of 82,144 live births were screened, with 9,555 PLTC, MNM or MD cases prospectively identified. Overall, any type of delay was observed in 53.8% of cases; delay related to user factors was observed in 10.2%, 34.6% of delays were related to health service accessibility and 25.7% were related to quality of medical care. The occurrence of any delay was associated with increasing severity of maternal outcome: 52% in PLTC, 68.4% in MNM and 84.1% in MD. Although this was not a population-based study and the results could not be generalized, there was a very clear and significant association between frequency of delay and severity of outcome, suggesting that timely and proper management are related to survival.
