Population health implications of exposure to pervasive military aircraft noise pollution.

BACKGROUND: While the adverse health effects of civil aircraft noise are relatively well studied, impacts associated with more intense and intermittent noise from military aviation have been rarely assessed. In recent years, increased training at Naval Air Station Whidbey Island, USA has raised concerns regarding the public health and well-being implications of noise from military aviation. OBJECTIVE: This study assessed the public health risks of military aircraft noise by developing a systematic workflow that uses acoustic and aircraft operations data to map noise exposure and predict health outcomes at the population scale. METHODS: Acoustic data encompassing seven years of monitoring efforts were integrated with flight operations data for 2020-2021 and a Department of Defense noise simulation model to characterize the noise regime. The model produced contours for day-night, nighttime, and 24-h average levels, which were validated by field monitoring and mapped to yield the estimated noise burden. Established thresholds and exposure-response relationships were used to predict the population subject to potential noise-related health effects, including annoyance, sleep disturbance, hearing impairment, and delays in childhood learning. RESULTS: Over 74,000 people within the area of aircraft noise exposure were at risk of adverse health effects. Of those exposed, substantial numbers were estimated to be highly annoyed and highly sleep disturbed, and several schools were exposed to levels that place them at risk of delay in childhood learning. Noise in some areas exceeded thresholds established by federal regulations for public health, residential land use and noise mitigation action, as well as the ranges of established exposure-response relationships. IMPACT STATEMENT: This study quantified the extensive spatial scale and population health burden of noise from military aviation. We employed a novel GIS-based workflow for relating mapped distributions of aircraft noise exposure to a suite of public health outcomes by integrating acoustic monitoring and simulation data with a dasymetric population density map. This approach enables the evaluation of population health impacts due to past, current, and future proposed military operations. Moreover, it can be modified for application to other environmental noise sources and offers an improved open-source tool to assess the population health implications of environmental noise exposure, inform at-risk communities, and guide efforts in noise mitigation and policy governing noise legislation, urban planning, and land use.

Estimating Real-World Performance of Percutaneously Coupled Bone-Conduction Device Users With Severe-to-Profound Unilateral Hearing Loss.

Purpose The bone-conduction device attached to a percutaneous screw (BCD) is an important treatment option for individuals with severe-to-profound unilateral hearing loss (UHL). Clinicians may use subjective questionnaires and speech-in-noise measures to evaluate BCD use in this patient population; however, the translation of these metrics to real-world aided performance is unclear. The purpose of this study was twofold: first, to measure speech-in-noise performance in BCD users with severe-to-profound UHL in a simulated real-world environment, relative to individuals with normal hearing bilaterally; second, to determine if BCD users' subjective reports of aided performance relate to simulated real-world performance. Method A between-subjects design with two groups was conducted with 14 adults with severe-to-profound UHL (BCD group) and 10 age-matched participants with normal hearing bilaterally (control group). Speech-in-noise tests were administered in an eight-speaker R-Space simulating a real-world environment. To further explore speech-in-noise evaluation methods for this population, testing was also completed in a clinically common two-speaker array. The effects of various microphone settings on performance were explored for BCD users. Subjective performance was measured with the Abbreviated Profile of Hearing Aid Benefit (APHAB; Cox & Alexander, 1995) and the Speech, Spatial and Qualities of Hearing Scale (Gatehouse & Noble, 2004). Statistical analyses to explore relationships between variables included repeated-measures analysis of variance, regression analyses, independent-samples t tests, nonparametric Mann-Whitney tests, and correlations. Results In the simulated real-world environment, BCD group participants struggled with speech-in-noise understanding compared to control group participants. BCD benefit was observed for all microphone settings when speech stimuli were presented to the side with the BCD. When adaptive directional or fixed directional microphone settings were used, a relationship was noted between simulated real-world speech-in-noise performance for speech stimuli presented to the side with the BCD and subjective reports on the Background Noise subscale of the APHAB. Conclusions The Background Noise subscale of the APHAB may help estimate real-world speech-in-noise performance for BCD users with severe-to-profound UHL for signals of interest presented to the implanted side, specifically when adaptive or fixed directional microphone settings are used. This subscale may provide an efficient and accessible alternative to assessing real-world speech-in-noise performance in lieu of less clinically available measurement tools, such as an R-Space.

The Association Between Maintaining American Board of Emergency Medicine Certification and State Medical Board Disciplinary Actions.

BACKGROUND: In certain medical specialties, board certification is associated with a lower risk of state medical board disciplinary actions. OBJECTIVE: The association between maintaining American Board of Emergency Medicine (ABEM) certification and state medical disciplinary actions had not been studied. This study was undertaken to determine if maintaining ABEM certification was associated with a lower risk of disciplinary action. METHODS: This investigation was a historical cohort study using Cox regression. Physicians who did not have a lapse in ABEM certification were compared with physicians who had a lapse to determine the risk of disciplinary action. Lapsing was determined at the expiration of the initial certificate. This study included all physicians who obtained initial ABEM certification from 1980-2005. Additional covariates of interest included the number of attempts on the ABEM Qualifying Examination (1 vs. >1), the geographic region of the physician's residence, and the country of medical school. RESULTS: There were 23,002 physicians in the study cohort. Of these, 3370 (14.7%) let their certification lapse after initial certification. There were 701 (3.0%) physicians with disciplinary events. Lapsed physicians had higher rates of disciplinary actions than physicians who did not lapse (6.4% vs. 2.5%). ABEM-certified physicians who did not lapse were significantly less likely to be disciplined as physicians who let their certificate lapse (hazard ratio 0.50 [95% confidence interval 0.42-0.59]). CONCLUSIONS: The absolute incidence of physicians with a disciplinary action in this study cohort was low (3.0%). Maintaining ABEM certification was associated with a lower risk of state medical board disciplinary actions.

Ferritin in serum and urine: A pilot study.

Serum ferritin reflects total body iron stores, thus a low serum ferritin is used as a parameter of iron deficiency. In healthy adults in Japan, urine ferritin levels were about 5% of serum ferritin levels, with a correlation coefficient of 0.79. It is not known whether a low urine ferritin could serve as a non-invasive screen for iron deficiency. If so, this might be useful for neonates and young children, avoiding phlebotomy to screen for iron deficiency. However, for urinary ferritin screening to be feasible, ferritin must be measurable in the urine and correlate with serum ferritin. Testing should also clarify whether the iron content of ferritin in serum and urine are similar. In this pilot feasibility study we measured ferritin in paired serum and urine samples of healthy adult males, healthy term neonates, growing preterm neonates, and children who had very high serum ferritin levels from liver disorders or iron overload. We detected ferritin in every urine sample, and found a correlation with paired serum ferritin (Spearman correlation coefficient 0.78 of log10-transformed values). These findings suggest merit in further studying urinary ferritin in select populations, as a potential non-invasive screen to assess iron stores.

Emergency medicine practice environment and impact on concert examination performance.

OBJECTIVE: The ABEM ConCert Examination is a summative examination that ABEM-certified physicians are required to pass once in every 10-year cycle to maintain certification. This study was undertaken to identify practice settings of emergency physicians, and to determine if there was a difference in performance on the 2017 ConCert between physicians of differing practice types and settings. METHODS: This was a mixed methods cross sectional-study, using a post-examination survey and test performance data. All physicians taking the 2017 ConCert Examination who completed three survey questions pertaining to practice type, practice locations, and teaching were included. These three questions address different aspects of academia: self-identification, an academic setting, and whether the physician teaches. RESULTS: Among 2796 test administrations of the 2017 ConCert Examination, 2693 (96.3%) completed the three survey questions about practice environment. The majority (N = 2054; 76.3%) self-identified as primarily being a community physician, 528 (19.6%) as academic, and 111 (4.1%) as other. The average ConCert Examination score for community physicians was 83.5 (95% CI, 83.3-83.8); the academic group was 84.8 (95% CI, 84.3-85.3); and the other group was 82.3 (95% CI, 81.1-83.6). After controlling for initial ability as measured by the Qualifying Examination score, there was no significant difference in performance between academic and community physicians (p = .10). CONCLUSIONS: Academic emergency physicians and community emergency physicians scored similarly on the ConCert. Working at a community teaching hospital was associated with higher examination performance. Teaching medical learners, especially non-emergency medicine residents, was also associated with better examination performance.

A Holocene landscape dynamic multiproxy reconstruction: How do interactions between fire and insect outbreaks shape an ecosystem over long time scales?

At a multi-millennial scale, various disturbances shape boreal forest stand mosaics and the distribution of species. Despite the importance of such disturbances, there is a lack of studies focused on the long-term dynamics of spruce budworm (Choristoneura fumiferana (Clem.)) (SBW) outbreaks and the interaction of insect outbreaks and fire. Here, we combine macrocharcoal and plant macrofossils with a new proxy-lepidopteran scales-to describe the Holocene ecology around a boreal lake. Lepidopteran scales turned out to be a more robust proxy of insect outbreaks than the traditional proxies such as cephalic head capsules and feces. We identified 87 significant peaks in scale abundance over the last 10 000 years. These results indicate that SBW outbreaks were more frequent over the Holocene than suggested by previous studies. Charcoal accumulation rates match the established fire history in eastern Canada: a more fire-prone early and late Holocene and reduced fire frequency during the mid-Holocene. Although on occasion, both fire and insect outbreaks were coeval, our results show a generally inverse relationship between fire frequency and insect outbreaks over the Holocene.

Well-Being among Emergency Medicine Resident Physicians: Results from the ABEM Longitudinal Study of Emergency Medicine Residents.

BACKGROUND: The Longitudinal Study of Emergency Medicine Residents (LSEMR) conducted by the American Board of Emergency Medicine queries a randomized cohort of emergency medicine (EM) residents. It is designed to identify residents' perceptions of their training, sources of stress, well-being level, and career choice satisfaction over time. OBJECTIVES: This study utilizes LSEMR to identify resident well-being levels, career satisfaction, factors producing stress, and whether a specific cohort is more stressed than the overall respondent group. METHODS: Data from five longitudinal cohorts were analyzed using descriptive statistics to assess stressors, career satisfaction, and self-reported resident well-being. Participants' answers were reported on a 5-point Likert scale. RESULTS: There were 766 residents who completed the survey in five cohorts. Respondents were 30 years old (median 29), male (66%), and predominantly White (79%). The most frequently encountered problems included "time devoted to documentation and bureaucratic issues," "knowing enough," and "crowding in the emergency department." In contrast, the least frequently reported problems included "gender discrimination," "EMS support," "minority discrimination," and "other residents." Respondents thought being an EM resident was fun and would select EM again. Less than 20% indicated they had seriously considered transferring to another EM program. Resident reports of health concerns changed over time, with fewer residents reporting they were exceptionally healthy in 2016. CONCLUSIONS: Residents are, overall, happy with their career choice. However, concern was expressed regarding continued well-being in training. Sources of stress in training are identified. Strategies should be developed to decrease identified stressors and increase well-being among EM residents.

Physician Age and Performance on the American Board of Emergency Medicine ConCert Examination.

OBJECTIVE: This study was undertaken to expand on results from a 2014 study on the association between physician age and performance on the American Board of Emergency Medicine (ABEM) ConCert examination. METHODS: This was a retrospective, longitudinal growth study comparing performance on the ConCert examination and physicians' ages at the time of examination. All examination attempts from 1990 to 2016 made by residency-trained physicians were eligible for inclusion. Multilevel growth models were constructed to examine the relationship between age at time of examination and performance, controlling for physician characteristics. RESULTS: The study group included 15,533 examination attempts by 12,786 physicians. The mean (±SD) age of the physicians across all examination administrations was 45.02 (±5.18) years (range = 35 to 72 years). The mean (±SD) ConCert examination score across all administrations was 85.39 (±5.71; range = 51 to 100). Among first-time ConCert examination takers, older age was associated with lower examination scores (r = -0.25, p < 0.0001). Across all examination attempts, age was negatively correlated to examination scores (r = -0.24; p < 0.0001). CONCLUSIONS: After physician characteristics were controlled for, there was an association between advancing age and declining performance on the ABEM ConCert examination. This information may be important to the individual physician to develop targeted competency assessment and professional development.

Initial Validity Analysis of the American Board of Emergency Medicine Enhanced Oral Examination.

OBJECTIVES: The American Board of Emergency Medicine (ABEM) has introduced a new testing format for the oral certification examination (OCE): the enhanced oral or "eOral" format. The purpose of this study was to perform initial validity analyses of the eOral format. The two hypotheses were: 1) the case content in the eOral format was sufficiently similar to clinical practice and 2) the eOral case materials were sufficiently similar to clinical practice. The eOral and traditional formats were compared for these characteristics. METHODS: This was a prospective survey study. The survey was administered as a voluntary postexamination activity at the end of the 2015 spring (April 25-27) and fall (October 10-13) ABEM OCEs. The survey is a routine part of the ABEM oral examination experience. For 2015, two additional questions were added to gauge the similarity of the eOral format to clinical practice. Validity was defined by content and substantive elements within Messick's model of construct validity as well as portions of Kane's validity model. RESULTS: Of the 1,746 physicians who took the oral examination, 1,380 physicians (79.0%) completed all or part of the study survey questions. The majority of respondents agreed the patient presentations in the cases were similar (strongly agreed or agreed) to cases seen in clinical practice, in both the traditional cases (95.1%) and the eOral cases (90.1%). Likewise, the majority of respondents answered that the case materials (e.g., laboratory, radiographs) were similar (strongly agreed or agreed) to what they encounter in clinical practice, both in the traditional format (85.8%) and in the eOral cases (93.7%). CONCLUSIONS: Most emergency physicians reported that the types of cases tested in the traditional and eOral formats were similar to cases encountered in clinical practice. In addition, most physicians found the case materials to be similar to what is seen in clinical practice. This study provides early validity evidence for the eOral format.

Evolution of the Model of the Clinical Practice of Emergency Medicine: 1979 to Present.

The Model of the Clinical Practice of Emergency Medicine (the EM Model) is a three-dimensional representation of the clinical practice of emergency medicine. It is a product of successful collaboration involving the American Board of Emergency Medicine (ABEM), the American College of Emergency Physicians (ACEP), the Society for Academic Emergency Medicine (SAEM), the Emergency Medicine Residents' Association (EMRA), the Council of Emergency Medicine Residency Directors (CORD), the Residency Review Committee for Emergency Medicine (RRC-EM), and the American Academy of Emergency Medicine (AAEM). In 2017, the most recent update and revision of the EM Model will be published. This document will represent the culmination of nearly 40 years of evolution, from a simple listing of presenting patient complaints, clinical symptoms, and disease states into a three-dimensional representation of the clinical practice of emergency medicine. These dimensions include conditions and components, physician tasks, and patient acuity. In addition, over the years, two other documents have been developed, the Knowledge, Skills, and Abilities (KSAs) and the Emergency Medicine Milestones. Both serve as related and complementary educational and assessment tools. This article will review the development of the EM Model from its inception in 1979 to today.

The American Board of Emergency Medicine ConCert Examination: Emergency Physicians' Perceptions of Learning and Career Benefits.

OBJECTIVE: As part of the American Board of Emergency Medicine (ABEM) Maintenance of Certification (MOC) program, ABEM-certified physicians are required to pass the Continuous Certification (ConCert) examination at least every 10 years. With the 2015 ConCert examination, ABEM sought to better understand emergency physicians' perceptions of the benefits of preparing for and taking the examination and the career benefits of staying ABEM-certified. METHODS: This was a prospective survey study. A voluntary postexamination survey was administered at the end of the 2015 ABEM ConCert examination (September 21-26, 2015). Physicians were asked about the benefits of preparing for the examination and maintaining ABEM certification. Examination performance was compared to perceptions of learning and career benefits. RESULTS: Of the 2,601 on-time test takers, 2,511 respondents participated (96.5% participation rate). The majority of participants (92.0%) identified a benefit to preparing for the ConCert examination, which included reinforced medical knowledge (73.9%), increased knowledge (66.8%), and making them a better clinician (39.4%). The majority of respondents (90.8%) identified a career benefit of maintaining ABEM certification, which included more employment options (73.8%), more positively viewed by other physicians (56.8%), and better financial outcomes (29.8%). There was a statistically significant association between the perception of knowledge reinforcement and examination performance (p < 0.001). There was also a statistically significant association between the perception that staying certified created more career opportunities and examination performance (p < 0.001). CONCLUSIONS: Most emergency physicians identified benefits of preparing for and taking the ABEM ConCert examination, which included reinforcing or adding medical knowledge and making them better clinicians. Most physicians also found career benefits to remaining ABEM-certified, which included greater employment choices, higher financial compensation, and higher esteem from other physicians. The belief that preparing for and taking the examination reinforced medical knowledge was associated with better examination performance.

Physician Preparation for the American Board of Emergency Medicine ConCert Examination.

OBJECTIVES: To maintain certification by the American Board of Emergency Medicine (ABEM), physicians are required to pass the Continuous Certification (ConCert) examination at least every 10 years. On the 2014 ConCert postexamination survey, ABEM sought to understand the manner in which ABEM diplomates prepared for the test and to identify associations between test preparation approaches and performance on the ConCert examination. METHODS: This was a cross-sectional survey study. The survey was administered at the end of the 2014 ConCert examination. Analyses included chi-square and linear regression to determine the association of preparation methods with performance. RESULTS: Of the 2,431 on-time test-takers, 2,338 (96.2%) were included. The most commonly used study approach was the review of written materials designed for test preparation (1,585; 67.8%), followed by an online training course (1,006; 43.0%). There were 758 (32.4%) physicians who took a single onsite board review course, while 41 (1.8%) took two or more onsite courses. Most physicians (1,611; 68.9%) spent over 35 hours preparing for the ConCert examination. The study method that was most associated with favorable test scores was the review of written materials designed for test preparation (p < 0.001). Attending an onsite preparation course was associated with poorer performance (p < 0.001). There was a significant association between no additional preparation and failing the examination (chi-square with Yates correction; p = 0.001). CONCLUSIONS: A substantial majority (97.8%) of physicians taking the 2014 ABEM ConCert examination prepared for it. The majority of physicians used written materials specifically designed for test preparation. Reviewing written materials designed for test preparation was associated with the highest performance.

From see one do one, to see a good one do a better one: learning physical examination skills through peer observation.

BACKGROUND: Learning and mastering the skills required to execute physical exams is of great importance and should be fostered early during medical training. Observing peers has been shown to positively influence the acquisition of psychomotor skills. PURPOSE: The current study investigated the influence of peer observation on the acquisition of psychomotor skills required to execute a physical examination. METHODS: Second-year medical students (N=194) learned the neurological physical examination for low back pain in groups of three. Each student learned and performed the physical examination while the other students observed. Analyses compared the impact of the quantity and the quality of observed performances on students' learning of the physical examination skills. RESULTS: Students benefited from observing peers while they executed their examination. Moreover, observing a high-performing peer increased the acquisition of physical examination skills. CONCLUSIONS: Results suggest that group learning activities that allow students to observe their peers during physical examination should be favored.

Baseball and softball sliding injuries: incidence and correlates during one high school league varsity season.

OBJECTIVE: To estimate injury rates associated with sliding in high school baseball and softball. DESIGN: Prospective cohort study. SETTING: Community high school athletic events. PARTICIPANTS: Ten high school varsity baseball and softball teams over 1 season. ASSESSMENT OF RISK FACTORS: All sliding attempts were recorded during each game and recorded as headfirst, feetfirst, or diveback. Base type, playing surface, and field conditions were also noted. MAIN OUTCOME MEASURES: Injury exposure rates by game exposures and sliding/diveback exposures. RESULTS: Data were collected from 153 baseball games and 166 softball games. A greater proportion of slides were associated with injury in softball than in baseball (42.0 and 4.9 per 1000 slides; P < 0.05). Headfirst slides led to more injuries than feetfirst slides in baseball (16.8 vs 0 per 1000 slides; P < 0.05) but not in softball (55 vs 35 per 1000 slides; P = 0.74). CONCLUSIONS: More powerful studies are required to determine whether efforts to prevent baseball sliding injuries at the high school level should focus on better education in sliding technique or changes in equipment. Softball players are vulnerable to injury when wearing inadequate protective sliding apparel.

The core content of emergency medical services medicine.

On September 23, 2010, the American Board of Medical Specialties (ABMS) approved emergency medical services (EMS) as a subspecialty of emergency medicine. As a result, the American Board of Emergency Medicine (ABEM) is planning to award the first certificates in EMS medicine in the fall of 2013. The purpose of subspecialty certification in EMS, as defined by ABEM, is to standardize physician training and qualifications for EMS practice, to improve patient safety and enhance the quality of emergency medical care provided to patients in the prehospital environment, and to facilitate integration of prehospital patient treatment into the continuum of patient care. In February 2011, ABEM established the EMS Examination Task Force to develop the Core Content of EMS Medicine (Core Content) that would be used to define the subspecialty and from which questions would be written for the examinations, to develop a blueprint for the examinations, and to develop a bank of test questions for use on the examinations. The Core Content defines the training parameters, resources, and knowledge of the treatment of prehospital patients necessary to practice EMS medicine. Additionally, it is intended to inform fellowship directors and candidates for certification of the full range of content that might appear on the examinations. This article describes the development of the Core Content and presents the Core Content in its entirety.

Collaborative practice: matching staff skills to patient needs and checking baseline staffing levels.

Vancouver Coastal Health uses a collaborative practice process to enable nursing units to be proactive and adapt quickly to changing patient population needs using a standardized and integrated approach. The process involves clinical directors, frontline managers, staff, and union representatives from the outset and is based on a registered nurse/licensed practical nurse/patient care aide collaborative model of practice. Results show a total return on investment in 2.4 years.

2007 survey of medical toxicology practice.

To date, there appear to be no studies investigating the practice settings of all Medical Toxicology (MT) diplomates. The MT Assessment of Practice Performance Taskforce queried all MT diplomates about their current practice settings relative to the number of patients seen, the most common diagnoses, and the percent of time spent in their roles as medical toxicologists (MTs) and in their primary specialty. One hundred twenty-seven surveys were completed (44% response rate). Seventy-nine percent of respondents were affiliated with poison centers. Eighty-eight percent of participants were clinically active and reported seeing or consulting on behalf of at least ten patients over a 2-year period. Acetaminophen toxicity was the most common diagnosis encountered by respondents. Other common diagnoses included antidepressant toxicity, antipsychotic toxicity, mental status alteration, metal/environmental toxicity, envenomation, and pesticide toxicity. While respondents were likely to spend more time in direct patient care in their primary specialty, compared to consulting on behalf of patients, they were more likely to consult on behalf of patients in their role as MTs. Respondents spent more time in research, education, and population health in their role as an MT than in their primary specialty. Administrative activities were more commonly reported in association with the respondents' primary specialty than in their role as MTs. Most MTs encounter certain diagnoses with significant frequency and see a substantial number of patients within these categories. The majority spends more time on direct patient care in their primary specialty but is actively engaged in MT education, research, population health, and administration. A longitudinal assessment of MT practice patterns could inform MT curricular development and practice performance evaluation.

2007 survey of medical toxicology practice improvement activities.

To date, there appear to be no studies that assess Medical Toxicologists' (MTs) practice improvement (PI) activities in their Medical Toxicology practice settings. The MT Assessment of Practice Performance (APP) Taskforce queried all MT diplomates about (1) activities currently available in their practice settings that potentially would meet the requirements of APP, (2) potential APP activities that best fit with current MT practice, and (3) the relationship between MT practice patterns and APP requirements. One hundred twenty-seven surveys were completed. Participation in MT practice improvement activities is not universal, with approximately a third of the survey participants reporting that they are not involved in any practice improvement activity. Few respondents reported that they collected performance improvement-related data. Most who did so participated in CME, case, or chart reviews. Peer reviews, self-improvement plans based on chart reviews, and population research were considered the most valid measures of MT practice improvement. Communication skills were considered important topics for patient surveys. Suggested outcomes for peer assessment included accuracy of information provided, understanding medical staff concerns, timeliness of feedback, and helpfulness. Most respondents rated all of the APP options as being somewhat very intrusive. Access to those with sufficient knowledge of the diplomate's practice improvement program to verify APP could pose a challenge to a successful completion of APP requirements. Optimal settings for the APP program administration are hospitals and poison centers. While barriers to MT APP activities exist, studying current MT diplomates' opinions and practices could inform the future development and administration of such programs.

Ovulation disturbances and mood across the menstrual cycles of healthy women.

We examined the cyclicity of negative mood relative to ovulation and ovulation disturbances in Menstrual Cycle Diary(c) data collected daily during a 1-year study of ovulation, exercise, and bone change. A validated quantitative basal temperature-based methodology was used to determine the onset of the luteal phase. 'Feeling depressed', 'feeling anxious', and 'feeling angry/frustrated' were scored on a scale of 0 (absent) to 4 (very intense). Mood scores were examined over two 15-day intervals centered on either ovulation/midpoint, or on the onset of flow. Data were available from 765 cycles of 62 healthy and initially ovulatory women with a mean age of 33.9 +/- 5.4 years. Of 739 cycles that could be classified, 532 (72%) were normally ovulatory, 185 (25%) were ovulatory with a short (<10 day) luteal phase, and 22 (3%) were anovulatory. Minor cyclic mood changes were present in both ovulatory and anovulatory menstrual cycles. In anovulatory cycles, mood tended to be more variable but less negative, with a time course that differed from that in ovulatory cycles. Mood scores did not differ based on luteal phase length or with hormone levels. Patterns and mechanisms of mood change in very symptomatic women appear to be essentially amplifications of normal experiences.

Medical school debt load of graduate anesthesiologists at a single medical school campus, 1982-2007.

Medical school debt continues to grow at an ever increasing rate. We questioned whether the debt incurred by the residents finishing their training at the University of Kansas School of Medicine-Wichita (UKSM-W) was overly burdensome. We surveyed all graduate anesthesiologists from UKSM-W. The returned questionnaires were tabulated and subjected to statistical analysis comparing two cohorts: those graduates finishing in the years 1982-1992 (earlier cohort) to those finishing in the years 1993-2007 (later cohort). There was a statistical difference in median debt load between the cohorts, $56,823 to $113,746 earlier versus later cohorts (constant dollars). The percentage of gross income required to repay the debt was the same for both cohorts. Both cohorts reported under-funding retirement plans and children's education to service debt. Few of either cohort chose practice location because of debt load.
