The psychological impact of mild ovarian stimulation combined with single embryo transfer compared with conventional IVF.
(49/266)
BACKGROUND: The objective of this study was to assess the psychological implications of mild ovarian stimulation combined with single embryo transfer (SET) during a first IVF cycle. METHODS: We conducted a randomized controlled two-centre trial. Three hundred and ninety-one couples were randomized to undergo either mild ovarian stimulation with GnRH antagonist co-treatment and SET (n=199) or conventional GnRH agonist long protocol ovarian stimulation with double embryo transfer (DET) (n=192). Women completed the Hospital Anxiety and Depression Scale, the Hopkins Symptom Checklist and the Subjective Sleep Quality Scale at baseline, on the first day of ovarian stimulation and following embryo transfer. Affect was assessed daily with the Daily Record Keeping Chart from the first day of ovarian stimulation until the day treatment outcome became known. RESULTS: The conventional IVF group experienced elevated levels of physical and depressive symptoms during pituitary downregulation. At oocyte retrieval, this group experienced more positive affect and less negative affect than the mild IVF group. In the conventional IVF group, cycle cancellation was associated with less positive and more negative affect. CONCLUSIONS: During the first IVF treatment cycle, mild ovarian stimulation and SET does not lead to more psychological complaints than conventional IVF. (+info)
Unhappiness and dissatisfaction in doctors cannot be predicted by selectors from medical school application forms: a prospective, longitudinal study.
(50/266)
BACKGROUND: Personal statements and referees' reports are widely used on medical school application forms, particularly in the UK, to assess the suitability of candidates for a career in medicine. However there are few studies which assess the validity of such information for predicting unhappiness or dissatisfaction with a career in medicine. Here we combine data from a long-term prospective study of medical student selection and training, with an experimental approach in which a large number of assessors used a paired comparison technique to predict outcome. METHODS: Data from a large-scale prospective study of students applying to UK medical schools in 1990 were used to identify 40 pairs of doctors, matched by sex, for whom personal statements and referees' reports were available, and who in a 2002/3 follow-up study, one pair member was very satisfied and the other very dissatisfied with medicine as a career. In 2005, 96 assessors, who were experienced medical school selectors, doctors, medical students or psychology students, used information from the doctors' original applications to judge which member of each pair of doctors was the happier, more satisfied doctor. RESULTS: None of the groups of assessors were significantly different from chance expectations in using applicants' personal statements and the referees' reports to predict actual future satisfaction or dissatisfaction, the distribution being similar to binomial expectations. However judgements of pairs of application forms from pairs of doctors showed a non-binomial distribution, indicating consensus among assessors as to which doctor would be the happy doctor (although the consensus was wrong in half the cases). Assessors taking longer to do the task concurred more. Consensus judgements seem mainly to be based on referees' predictions of academic achievement (even though academic achievement is not actually a valid predictor of happiness or satisfaction). CONCLUSION: Although widely used in medical student selection to assess motivation, interest and commitment to a medical career, the personal statement and the referee's report cannot validly be used by assessors, including experienced medical school selectors, to identify doctors who will subsequently be dissatisfied with a medical career.

Insights from students following an educational rotation through dental geriatrics.
(51/266)
Little is known about how dental students respond to dental geriatrics. This article describes a qualitative analysis of reflective journals submitted over two years by ninety-two senior students who participated in a brief clinical rotation in long-term care facilities. We used an inductive interpretive approach to analyze the journals. Eight themes emerged from the analysis: 1) complexity of the institutional environment; 2) heterogeneity of the resident population; 3) multidisciplinary environment; 4) record keeping; 5) interactions with residents; 6) the difficulty of oral health care for frail residents; 7) bridging the gap between theory and practice; and 8) the emotional impact of the clinical experiences. Apparently, the students appreciated the opportunity to witness the complexity of care in a multidisciplinary context and to observe a practical program of oral health care. They described the rotations as unique and emotionally challenging but very worthwhile. Overall, they wrote positively about their experiences with the elderly residents, acknowledged the contribution of the rotation as important to their clinical maturation, and reported that the experience enhanced their appreciation of a dentist's professional responsibilities.

Dental clinical teaching: perceptions of students and teachers.
(52/266)
The objective of this study was to explore perceptions of dental student clinicians and clinical teachers about dental clinical teaching to provide primary data for dental researchers and educators. Student focus group data provided background for development of a questionnaire that explored three themes related to clinical teaching. Twenty-one teachers and forty-five student respondents completed the twenty-five-item questionnaire in 2003. In the theme of the teacher/student relationship, no statistically significant differences were seen between teacher and student group perceptions. In the theme of educational theory applied in dental clinical teaching, a statistically significant difference was seen between teacher and student groups in the value of preclinical instruction in senior clinical years and in the value of a clinical log book. In the theme of skills required for clinical dental practice, a statistically significant difference was seen between teacher and student groups in the value of a critical appreciation of evidence-based practice as one of the skills. The study overall indicates that the dental clinical learning environment supports close perceptual conformity between students and clinical teachers in regard to what each group considers to be "good practice" in clinical teaching. The findings of this study indicate that some techniques that have been advocated to enhance clinical learning, such as evidence-based teaching methods, require further investigation. (+info)
Accessing NCI's SEER cancer data base with SeerQuery and CD-ROM.
(53/266)
The National Cancer Institute operates the Surveillance, Epidemiology, and End Results (SEER) cancer data base. SEER data are obtained from participating population-based registries that monitor cancer incidence and patient survival in a representative 10 percent sample of the general population. The data cover all cancers (except superficial skin cancers) in the defined regional populations. SeerQuery is a personal computer program for accessing that data on IBM-compatible personal computer compact diskettes in read-only memory (CD-ROM) form. SeerQuery facilitates rapid access to cancer data at minimal cost and effort to the user. SeerQuery is menu-driven, enabling physicians and other health care professionals to query the data base directly. They can use the data to determine cancer frequency, perform cross-tabulation, determine incidence, and calculate survival using such variables as primary cancer site, histologic type, stage, sex, age, and race. The comprehensive data base lacks many selection biases that are inherent in data reported from other sources. SeerQuery has applications in professional education and in cancer control program planning and resource allocation. (+info)
Timeliness of notification in infectious disease cases.
(54/266)
Records of notification in cases of eight infectious diseases in the "Servei Territorial de Salut Publica" of the Province of Barcelona, Spain, between 1982 and 1986 were reviewed. Time from onset of symptoms to notification, time from notification to completion of data collection, and time from onset to completion of the case investigation were analyzed. For the period from onset to notification, the shortest mean was registered for meningococcal infection (6.31 days) and the longest was for pulmonary tuberculosis (54.79 days). For time from notification to complete investigation, the shortest value was for pulmonary tuberculosis (12.20 days) and the longest for rickettsioses (35.79 days). Time from onset to completion of data collection was 22.87 days for meningococcal infection and 72.34 days for tuberculosis of other organs (probably because of the long period of time that elapses between the onset of the first symptoms and notification). It would appear that both physicians and the general population must be educated so that lay-men can identify early signs and symptoms of disease and physicians can realize that statutory notification of infectious diseases is strongly linked to community health care.

A critical evaluation of the electronic surgical logbook.
(55/266)
BACKGROUND: The Association of Surgeons of Great Britain and Ireland (ASGBI) devised the electronic surgical logbook (version 2.4) for higher trainees in General Surgery enabling trainees to compile a uniform data set of their operative and training experience. This is in use by higher surgical trainees (HST) in the United Kingdom. This logbook permits trainees to submit data centrally into a Regional Analysis Database (RAD). With the implementation of the European Working Time Directive (EWTD) there is need for reliable data to assess the effects of the directive on training. In order to draw meaningful conclusions from the database the quality of data needs to be validated. We critically analysed the RAD in the Yorkshire region for a one-year period. METHODS: The RAD from the ASGBI for the Yorkshire region was analysed. Data for the period 01/10/2002-30/09/2003 was identified and interrogated using Microsoft Excel (2000 version). The RAD was compared with information obtained from the Regional Surgical Advisor for Yorkshire with respect to hospitals, surgical consultants and HST's in the region during the study period. RESULTS: There were 13,755 operations entered for the study period. 579 corrections to the data had to be made (4.2%) and a further 1140 entries were deleted (8.2%). Following corrections and deletions 12,615 operative entries were available for analysis. Overall 12.5% of the data required either correction or exclusion from the database prior to analysis. CONCLUSION: The RAD has a large dataset useful to monitor and assess training. However, the quality of the data needs to be verified prior to use. Recommendations have been made to develop the ASGBI logbook, which would eventually translate to improved data reliability of the RAD. (+info)
Epidemiology of a primary pneumonic plague in Kantoshu, Manchuria, from 1910 to 1911: statistical analysis of individual records collected by the Japanese Empire.
(56/266)
BACKGROUND: Among the potential uses of Yersinia pestis, intentional release of its aerosolized form, causing person-to-person transmission, is thought to be the most threatening. With the current rarity of pneumonic plague epidemics, our epidemiological knowledge remains insufficient for detailed characterization of effective control measures. METHODS: Temporal patterns and key biological parameters of a pneumonic plague epidemic in Manchuria from 1910 to 1911 were analysed based on historical records collected by Kanto Totokufu, the administration of the Japanese Empire in Manchuria at that time. The serial intervals were fitted to gamma distribution using the maximum likelihood method, and time-delay distributions from onset-to-admission, admission-to-death, and onset-to-death were investigated. RESULTS: Whereas a total of 228 cases were diagnosed with pneumonic plague in areas under direct control of the Japanese Empire, 4,781 cases were also recorded in surrounding areas. Although the epidemic grew exponentially in the early phase, the average doubling time steadily increased reflecting successful control efforts. The estimated mean serial interval (and standard deviation) was 5.7 (3.6) days. All cases with known dates of onset were admitted to hospital within 4 days after onset, and the mean time from onset to admission was 1.1 (0.4) days. CONCLUSIONS: The increase in doubling time demonstrates the efficient and rapid countermeasures employed. Since the short interval from onset to death implies the importance of rapid responses, the challenge in confronting a future bioterrorist attack is to implement rapid and appropriate integration of control measures both at the individual and community level to prevent further transmissions as well as lower case fatality.
