Relation of family responsibilities and gender to the productivity and career satisfaction of medical faculty

BACKGROUND: Studies have found that female faculty publish less, have slower career progress, and generally have a more difficult time in academic careers than male faculty. The relation of family (dependent) responsibilities to gender and academic productivity is unclear. OBJECTIVE: To describe dependent responsibilities by gender and to identify their relation to the aspirations, goals, rate of progress, academic productivity, and career satisfaction of male and female medical school faculty. DESIGN: 177-item survey questionnaire. SETTING: 24 randomly selected medical schools in the contiguous United States. PARTICIPANTS: 1979 respondents from a probability sample of full-time academic medical school faculty. MEASUREMENTS: The main end point for measuring academic productivity was the total number of publications in refereed journals. Perceived career progress and career satisfaction were assessed by using Likert scales. RESULTS: For both male and female faculty, more than 90% of time devoted to family responsibilities was spent on child care. Among faculty with children, women had greater obstacles to academic careers and less institutional support, including research funding from their institutions (46% compared with 57%; P < 0.001) and secretarial support (0.68 full-time equivalents compared with 0.83 full-time equivalents; P = 0.003), than men. Compared with men with children, women with children had fewer publications (18.3 compared with 29.3; P < 0.001), slower self-perceived career progress (2.6 compared with 3.1; P < 0.001), and lower career satisfaction (5.9 compared with 6.6; P < 0.001). However, no significant differences between the sexes were seen for faculty without children. CONCLUSIONS: Compared with female faculty without children and compared with men, female faculty with children face major obstacles in academic careers. Some of these obstacles can be easily modified (for example, by eliminating after-hours meetings and creating part-time career tracks). Medical schools should address these obstacles and provide support for faculty with children.     

Academic faculty practices: issues for viability in competitive managed care markets

This study compares the perspectives of eighteen managed care executives and twenty-four faculty practice executives on critical policy issues related to the managed care marketplace. Market sites studied in 1994 included four major metropolitan areas: Minneapolis-St. Paul, Los Angeles, Philadelphia, and Atlanta. These markets were selected as being representative of communities with descending degrees of managed care involvement, but with significant market activity. Study participants from both managed care systems and faculty practices examined five policy issues: (1) the importance of including academic medical centers in current and future health care plans for marketing purposes; (2) the provision of clinical services that are unique to the academic medical center, that is, unavailable elsewhere in the community; (3) the degree of financial supplement that employers might pay for including an academic medical center; (4) future restructuring of organizations to sustain the educational mission of academic faculty within a viable delivery system; (5) satisfaction of managed care providers with graduates of academic medical centers, as measured by the clinical skills of graduate physicians. The study findings showed little support among managed care plans for paying supplements to include faculty practices in a health care network. Most study participants from managed care systems and academic faculty practices identified limited competencies that are unique to academic centers. Moreover, managed care organizations were only willing to undertake limited restructuring at best to include faculty practices within their networks. General concern about the preparation of resident physicians (especially those in primary care disciplines) for practice within contemporary managed care organizations existed among managed care informants. The results of the study indicate that as traditional funding sources for medical education are reduced, schools require greater integration with managed care plans to enable academic medical centers and their faculties to continue promoting clinical enterprise.     

Public health nurse staffing requirements for health examination of infants and children in municipalities of Japan

PURPOSE: Little is known about the impact of school-based primary care on adolescents' use of hospital and emergency room care. METHODS: Students (grades 6-12) in nine Baltimore schools with school-based health centers and four schools without health centers were surveyed in May 1991 using an anonymous classroom questionnaire. Self-reported use of primary care services and emergency rooms and hospitalization were examined over the academic year. Logistic regression was used to assess factors influencing use of health care including the presence of a school health center. RESULTS: Students (n = 3,258) in health center schools and comparison schools reported similar rates of chronic health conditions. Students from schools with health centers were more likely to report seeing a social worker or counselor and more likely to report the use of certain health services in the past 4 years. Self-reported emergency room use (38%) and hospitalization (19%) were common. Students in schools with health centers were less likely to report hospitalization (OR = 0.80, 95% CI = 0.66-0.98). Emergency room use was also lower but only for students attending the school with a health center for more than 1 year (OR = 0.78, 95% CI = 0.62-0.99). Significant predictors of hospital care included reporting one or more chronic health condition, having health insurance, being of African-American race, or older age, and lower grade. CONCLUSIONS: Access to school-based, primary health care for adolescents was associated with increased use of primary care, reduced use of emergency rooms, and fewer hospitalizations. These findings have implications for both access to primary care and funding of school-based primary care.     

Elevated serum neopterin level: its relation to endotoxaemia and sepsis in patients with major burns

The present study was conducted to determine the relationship between levels of neopterin and endotoxin in the circulation, and whether the neopterin level was related to the development of severe sepsis after extensive burns. This prospective study included 35 patients with burn size greater than 30% (30-98%), and 22 healthy volunteers who served as a comparison group. Neopterin levels increased in most patients on day 3 post-burn, but they were not significantly correlated with the extent of the burn surface (P > 0 center dot 05). A high serum neopterin level was found in patients with sepsis (n = 15), and a marked elevation persisted throughout the observation period. The difference between septic and non-septic patients (n = 20) became significant on 14 and 28 days post-burn. Although the presence of early endotoxaemia did not influence the alterations in serum neopterin, patients with endotoxaemia had much higher neopterin values than those who showed no endotoxaemia from the second week onward (P < 0 center dot 05-0 center dot 01). In addition, circulating endotoxin and neopterin levels were positively correlated in patients who developed endotoxaemia on day 14 (r = 0 center dot 368, P < 0 center dot 05) and day 21 (r = 0 center dot 439, P < 0 center dot 01) after major burns. These results suggest that thermal injury can lead to an elevation of serum neopterin independent of the burn surface area. The initial increase in the neopterin level may be a part of the acute-phase response to tissue injury itself, whereas the endotoxin release in the circulation may be responsible for the continuous induction of neopterin during the late stage. In addition, the presence of a constant high neopterin level is associated with a critical event in the development of severe burn sepsis.     

Establishing albumin levels in sheep serum by a specific fluoroimmunoassay

The study determined the policies and procedures for the control and prevention of methicillin-resistant Staphylococcus aureus (MRSA) and its prevalence among nursing and residential homes, and evaluated whether certain home characteristics such as bed size, staffing level, and type of home are related to the prevalence of MRSA. A 21-questionnaire survey, with primarily categorical responses, was mailed to the home managers of all the 121 nursing and residential homes in the district, following which a simple, stratified random sample of 28 (23.14%) homes was taken and all agreeing residents screened from multiple sites for MRSA. Seventy-seven (63.6%) homes returned a completed questionnaire, 13 (46.4%) of whom agreed to participate in the microbiological study. The response rates for returning questionnaires and agreeing to participate in the microbiological study were similar for nursing and residential homes (65% vs. 60%; 67% vs. 40%; P = 0.12; P = 0.62), respectively. Nursing homes had a mean bed size of 30 (95% Confidence Interval (CI) 17-43), not significantly different from residential homes of 23 (95% CI 18-27; P = 0.26). The nursing homes employed a mean of 8.6 (95% CI 4.7-12.5) staff nurses per home; significantly higher than residential homes with a mean of 1.6 (95% CI 0.3-2.8; P = 0.006). No significant differences in mean number of home care assistants employed per home (22.8; 95% CI 12.4-33.13; and 14.4; 95% CI 11.83-16.90; P = 0.098, for nursing and residential homes, respectively) were observed. None of the homes had employed infection control practitioners. Only four (6.8%) of the responding homes stated that MRSA was a problem. Nursing homes were not significantly more likely to have admission policies for colonized person than residential homes (10/13 vs. 40/55, P = 1.00). Of the fifty-five (71.4%) homes who had admission policies, 40 (72.7%) stated that persons colonized/infected with MRSA would not be accepted, while 12 (21.8%) would accept such persons in single-room isolation and/or barrier nursing. Greater proportions of residential homes than nursing homes would not accept admission of persons with documented MRSA colonization (30/35 vs. 4/10, P = 0.007). Four (9.1%) homes (three nursing) had identified a total of five residents colonized/infected with MRSA in 5 years prior to the survey. Two hundred and forty-six residents were screened (552 sites), two (0.81%) of whom were found to be colonized in the nose (one resident) and in the groin (two residents) with MRSA, giving a 2-month weighted point prevalence rate of 0.14% (95% CI 0.01-0.26%). We conclude that in our district the nursing staffing levels and control measures vary widely within these homes, while the prevalence of residents who are colonized/infected with MRSA is lower than in other areas. We suggest that the exclusion admission policy for MRSA positive patients should be abandoned and targeted infection control programmes be instituted.     

Factors related to glycemic control in IDDM and insulin-treated NIDDM patients in current practice. A comparison of care policies. SIEMTIC Group. Studio Italiano Epidemiologico Multicentrico su Terapia Insulin e Controllo Metabolico

OBJECTIVE: To evaluate, under routine conditions, the relation between different diabetes care policies and glycemic control through a by-center analysis procedure aimed at reducing some drawbacks of cross-sectional data. RESEARCH DESIGN AND METHODS: A survey on insulin-treated diabetes care management (IDDM and NIDDM) involved 16 Italian randomly selected diabetes outpatient clinics. A total of 2,142 representative patients were investigated. The standardized HbA1c average value of each center was related, by regression models, to some indicators of center care policy (average number of injections, average BMI, proportion of cases with recent fundus oculi examinations, or frequent visits) as well as to patients' average social levels (employment type). Homogeneity in patient admission criteria is assumed among the investigated centers as a basic condition for the procedure validity. Some known imbalance were controlled for both design and analysis. RESULTS: HbA1c showed a univariate inverse relation with daily number of injections in IDDM (P = 0.0009, r2 = 0.56) but not in NIDDM (P = 0.33). It was inversely related to both fundus examination (IDDM P = 0.04; NIDDM P = 0.099) and qualified employment (IDDM P = 0.06; NIDDM P = 0.026). A stepwise regression analysis left in the model insulin injections (P = 0.0002) in IDDM (total r2 = 0.68) and qualified employment (P = 0.016) and fundus examination (P = 0.14) in NIDDM (total r2 = 0.53), after controlling for age, sex, disease duration, insulin therapy starting delay, and insulin dose per kilogram. CONCLUSIONS: These results suggest that the confirmed benefits of a multiple-injection regimen in IDDM cannot be simply extrapolated to NIDDM, where patients' awareness and medical attention to complications proved to be the most important factors in current practice.     

Clostridium difficile infection is a risk factor for bacteremia due to vancomycin-resistant enterococci (VRE) in VRE-colonized patients with acute leukemia

A cohort study was conducted in a cancer center to identify risk factors for bacteremia with vancomycin-resistant enterococci (VRE) in neutropenic cancer patients colonized with VRE. There were 10 patients with VRE bacteremia among 56 colonized with VRE, of whose charts 51 were available for review. One hundred percent of patients with VRE bacteremia (10 of 10) vs. 56% of patients without VRE bacteremia (23 of 41) had acute leukemia (P = .01, Fisher's exact test). Four of the 10 patients with VRE bacteremia had a positive Clostridium difficile toxin assay within 6 days of their first positive VRE blood culture. Both C. difficile infection and antimicrobial (vancomycin and ciprofloxacin) use during VRE colonization were significant risk factors for VRE bacteremia in univariate analysis. When a Cox proportional hazards model was used to account for differences in follow-up time, C. difficile infection was the only statistically significant risk factor (risk ratio, 8.2; P = .007) for VRE bacteremia in VRE-colonized patients with acute leukemia.     

Safeguarding the administration of high-dose chemotherapy: a national practice survey by the American Society for Blood and Marrow Transplantation

Overdoses of high-dose chemotherapy before hematopoietic cell transplantation are serious adverse events, but their frequency and etiology are unknown. The American Society for Blood and Marrow Transplantation (ASBMT) conducted an anonymous national survey to identify errors in safety practices during the administration of high-dose chemotherapy. The questionnaire was returned from 115 (68%) of 170 hematopoietic transplant centers in the United States. Ninety-four of the programs were university or affiliated centers, 19 were community hospitals, and 41 were founded since 1990. A total of 7650 transplants were reported for 1994: 22% of the programs performed 1-20 transplants, 60% performed 21-100 transplants, and 18% performed more than 100 transplants. Fifteen of the 115 responding centers reported a total of 18 patients inadvertently given overdoses of cisplatin (n=3), carboplatin (n=2), busulfan (n=2), cytosine arabinoside (n=2), cyclophosphamide (n=2), interleukin-2 (n=2), or other agents (n=5) between 1989 and 1994. Cumulative drug doses given as a daily dose (six cases) and nursing infusion errors (six cases) were the most common errors. The estimated chemotherapy overdose error rate was 0.06%, or 6 cases/10,000 transplants, with 95% confidence limits of 0.03-0.11%. The overdose rate among more experienced centers in operation before 1990 was lower than that among newer centers (p < 0.01). Large centers (> 100 transplants performed in 1994) experienced errors at rates lower than those in medium-sized centers (21-100 transplants, p = 0.03). Although the number of events was small in this self-reporting survey, overdoses were noted in 13% of the responding centers, especially among more recently established units. Safety practices need to emphasize multidisciplinary checkpoints at the physician, pharmacist, nursing, and institutional levels. Based on these survey results, ASBMT recommendations for further safeguards for high-dose chemotherapy administration are proposed.     

The physician decision-making process in transferring nursing home patients to the hospital

BACKGROUND: Each year more than 25% of nursing home patients are transferred to the emergency department or hospital for evaluation and treatment of infection. These transfers may have an adverse impact on the quality and cost of patient care. This study examined physician assessment and management of acute infections in the nursing home. METHODS: A cross-sectional study was conducted of all acute urinary tract infections and lower respiratory tract infections occurring from February through June 1991 in eight randomly selected urban nursing homes. The numbers of transfers to the emergency department of hospital were recorded along with identification of the clinical, psychosocial, and institutional factors that influenced the physician's decision to transfer. RESULTS: Three hundred fifty-nine patients had 258 urinary tract infections and 219 respiratory tract infections. Eighty-one (17%) of these events resulted in transfer to a hospital for evaluation (16/81) and/or admission (65/81). Less than one third (30.4%) of the events caused the patient to be examined in the nursing home by a physician before the decision to transfer to the hospital. The mean time between the staff notification of an acute event and physician response by telephone was 5.12 hours. Independent mobility (P < or = .05), a transfer to the hospital during the previous 6 months (P < or = .01), and fewer nursing home laboratory tests and treatments (P < or = .01) were all associated with hospital transfer. CONCLUSIONS: In this sample of acutely ill nursing home patients, physicians collected limited clinical data before the decision to transfer. Although some transfers may be appropriate, a reduction in the transfer rate may reduce health care costs and limit the risk of iatrogenesis, thus improving the outcome of acute illnesses occurring in the nursing home.     

Mixed messages about primary care in the culture of U.S. medical schools

PURPOSE: To examine the contributions of school-level variables associated with primary care career choice to students' enthusiasm for and perceived encouragement toward primary care. METHOD: Multilevel analysis of 264 fourth-year students and 500 clinical faculty members at 59 medical schools using data obtained in 1993 to 1994 from telephone interviews of a national stratified probability sample of students (response rate 90%) and faculty (response rate 81%). RESULTS: On average, students reported slightly positive regard for primary care and felt neither supported nor unsupported in their interests in primary care. Students' reports of encouragement toward primary care showed some consistency within schools (intraclass correlation = .08); their regard for primary care did not (intraclass correlation = .02). Regard for primary care was associated with students' intended specialty choices (p < .001), with students who planned to enter primary care careers reporting more positive attitudes. Students' perceptions of encouragement toward primary care careers were unrelated to their intended specialty choices, but significantly related to their schools' historical primary care production (p < .0001), federal research funding (p < .01), and school ownership (p < .01). CONCLUSION: Schools that have primary care missions and have historically produced more generalists transmit higher levels of encouragement to their students about primary care. However, even at schools with strong primary care missions, students hold unenthusiastic attitudes about primary care practice.     

Increased prevalence of cardiac arrhythmias and transient episodes of myocardial ischemia in hypertensives with left ventricular hypertrophy but without clinical history of coronary heart disease

To evaluate the behavior of cardiac arrhythmias (CA) and transient episodes of myocardial ischemia (TEMI), in relation to the circadian pattern of blood pressure in patients suffering from arterial hypertension, with or without echocardiographically ascertained left ventricular hypertrophy (LVH), we studied 128 patients, 87 men (M) and 41 women (F), aging from 21 to 76 years, subdivided into two groups: Group I, including 66 patients with LVH (45 M and 21 F; mean age of 53.7 +/- 9.1 years; Group II, including 62 patients without LVH (42 M and 20 F; mean age of 49.7 +/- 9.5 years). Office blood pressure (OBP) as well as nighttime ambulatory blood pressure (ABP) were higher in patients with LVH (P < .05 and P < .01). CA were present in a higher number of patients of Group I (P < .001): premature supraventricular beats (PSVB) 22.7 v 4.8%, supraventricular couplets (SVC) 36.4 v 16.1%, supraventricular tachycardia runs (SVT runs) 27.3 v 12.9%, ventricular ectopic beats (VEB) 25.6 v 8.0%, ventricular couplets (VC) 30.3 v 12.9%, ventricular tachycardia runs (VT runs) 12.1 v 3.2%. The absolute number of ectopic beats was also significantly higher in patients of Group I. Ventricular arrhythmias were significantly related to ASBP (r = 0.83, P < .01), to ADBP (r = 0.74, P < .01) and to heart rate (r = 0.87, P < .01) in patients of Group I. TEMI were more frequent in patients of Group I (73 v 41 episodes, 39.39% v 25.8% of patients, P < .01) and were related to ABP peaks. In fact, in both groups of patients all TEMI without heart rate increase and most TEMI with heart rate increase were registered between 6:00 and midnight, hours in which ABP values were higher. We conclude that hypertensives with LVH, but without clinical history of coronary heart disease, have a higher prevalence of ventricular arrhythmias and of transient episodes of myocardial ischemia in relation to the circadian pattern of ABP.     

Complex stenosis morphology predicts late reocclusion during follow-up after myocardial infarction in patients with patent infarct-related coronary arteries

BACKGROUND: Whether angiographic morphology of infarct-related residual stenoses continues to affect prognosis after discharge is not known. METHODS: We studied 175 patients after their myocardial infarction who required nonurgent coronary angioplasty for residual myocardial ischemia. The findings at diagnostic coronary angiography were compared with those before angioplasty (mean of 7 months later). Infarct-related stenoses were classified as complex or smooth. Stenosis progression was defined as >0.5 mm diameter reduction. RESULTS: One hundred twenty-one (69%) infarct-related stenoses were complex. At restudy, total occlusion was found in 41 (35%) of the infarct-related complex stenoses compared with 7 (13%) smooth stenoses (P = .001). Reocclusion occurred in 16 (55%) of 29 complex infarct-related stenoses with thrombus, compared with 25 (28%) of 88 without thrombus (P = .01). During follow-up, 46 patients (26%) had cardiac events. Of these, 70% had complex lesions at study entry compared with 30% smooth (P < .05). CONCLUSIONS: Residual angiographically complex stenoses after an uncomplicated myocardial infarction are associated with a greater risk of reocclusion and may predispose to coronary events at follow-up.     

Metastatic dermatofibrosarcoma protuberans mimicking meningioma

Relationships between body mass index (BMI) and weight gain with perinatal outcome and birthweight were examined. BMI was calculated on 582 consecutive pregnant women who delivered at or >37 weeks gestational age. Statistical analysis was done using Chi-square tests, analysis of variance, and multiple logistic regression. Of those studied, 13% were underweight, 39% normal, 13% overweight, and 35% obese. Obesity was associated with increasing age (P < .01), multiparity (P < .01), previous cesarean delivery (P < .01), previous macrosomia (P = .01), previous fetal death (P = .03), hypertensive disorders (P < .01), gestational diabetes (P = .02), cesarean delivery (P = .03), and neonatal intensive care unit admission (NICU) (P = .01). The underweight group had the most low birthweight (LBW) infants and the lowest mean birthweight. Ideal weight gain occurred in 31%, inadequate weight gain in 34%, and excessive weight gain in 35%. Inadequate weight gain had increased asthma (P < .05), and hyperemesis (P = .03). Women with ideal weight gain had less smokers (P < .01), fetal distress (P < .05), cesarean delivery (P = .02), and preeclampsia (P < .001). The mean birthweight was highest in the excessive weight gain (P < .01). With multivariate analysis, previous LBW, BMI, and tobacco use were significant predictors of LBW. Normal BMI and ideal weight gain in pregnancy is associated with decreased perinatal complications and an optimum birthweight.     

Stress-induced alterations of somatodendritic 5-HT1A autoreceptor sensitivity in the rat dorsal raphe nucleus--in vitro electrophysiological evidence

The role of trauma in the etiology of temporomandibular disorders (TMD) is controversial. The objectives of this study were to compare presenting signs, symptoms, and diagnoses in patients who had motor vehicle accident trauma-related TMD to patients who had nontrauma-related TMD. Files of 50 trauma and 50 matched nontrauma TMD patients were reviewed. Information concerning presenting pain, temporomandibular joint (TMJ) and related symptoms, examination findings, and diagnoses was recorded. Posttraumatic TMD patients reported higher facial (P = .006) and headache (P = .0001) pain ratings, neck symptom frequency (P < .01), ear-related symptoms (P = .02), sleep disturbance (P < .001), and occupational and avocational disability frequencies (P < .0001). They had greater masticatory muscle (P < .001), neck muscle (P < .001), and TMJ tenderness (P = .01) scores and myofascial pain (P = .006) and arthralgia/capsulitis (P = .008) diagnoses. The nontrauma group had more subjective (P = .02) and objective (P = .05) TMJ crepitus and higher self-reports of parafunctional jaw habits (P = .05). Trauma may be an important etiologic factor for some TMD patients.     

Evaluation of nursing faculty through observation

The purpose of this study was to assess current use and faculty perceptions of classroom observation as a method of faculty evaluation in schools of nursing. Baccalaureate schools of nursing were surveyed to determine current use of classroom observation and its worth from the perception of administrators and faculty. Although most schools used classroom observation as a method of faculty evaluation, further clarification and research is needed in the following areas: purpose of classroom observation; number of observations necessary; weight given to classroom observation in relation to other evaluation methods; and tools used.     

A survey of training in rehabilitation psychology practice in the United States and Canada: 2007.

Objective: Examine the structures, processes, and outcomes of training for rehabilitation psychology practice in the United States and Canada during 2007. Methods: Public data sources provided 947 potential training sites and programs, with 635 meeting selection criteria, from which 328 unique sites were identified. Of these, 117 sites (36%) reported providing training in rehabilitation psychology practice, and were sent a survey. Eighty percent (80%) returned the survey (n = 94). Results: There were nearly equal numbers of intern and resident training sites. Of the resident training sites, 46% had a complete rehabilitation focus, and 41% had faculty with American Board of Rehabilitation Psychology (ABRP) certification. Resident training sites ranged from 73% to 100% in meeting the Patterson and Hanson (1995) training guidelines, and ranged from 7% to 100% in formally teaching the current ABRP required competencies. Discussion: Many rehabilitation patients receive psychological services from practitioners whose professional emphasis is not in rehabilitation psychology, and many trainees involved with rehabilitation populations do not receive comprehensive training in rehabilitation psychology. There is a need for increased structure in and funding of training programs for rehabilitation psychology practice. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Resident training in nursing home care: survey of successful educational strategies

OBJECTIVE: To identify educational strategies for resident training in nursing home care deemed successful by a large number of programs. DESIGN: A mail survey with three follow-up mailings. PARTICIPANTS: Directors of accredited internal medicine and family practice residency programs. MEASUREMENTS: Open- and closed-ended questionnaire eliciting curricular content, instructional strategies, and evaluation techniques from programs offering a nursing home experience. Identification of barriers to implementation of a nursing home curriculum and recommendations for success were requested. MAIN RESULTS: Of the 814 surveys mailed, 537 were returned for a response rate of 66%. Nursing home experiences were required in 86% of family practice residency programs but in only 25% of internal medicine programs. Most geriatric medicine curricular content areas were taught in the nursing home; however, relatively little emphasis was given to rehabilitation, organization, and financing of health care, and coordination of care between acute and chronic settings. Direct patient care, bedside rounds, and lectures were the most common instructional strategies reported. Evaluation approaches included faculty observations, resident attendance, and chart reviews with written and skill-based examinations infrequent. Availability of faculty and conflict with other rotations were identified as the principal barriers to implementation of nursing home rotations. An organized nursing home curriculum supervised by enthusiastic faculty using a longitudinal rotation format with resident involvement in an interdisciplinary team was recommended. CONCLUSIONS: Educational strategies exist for successful implementation of a residency nursing home curriculum. Greater priority must be given to training residents in nursing home care and developing nursing home faculty to substantially increase the number and quality of physicians who practice in this setting.     

Gonadotropin-releasing hormone enhances the calving rate of beef females administered norgestomet and alfaprostol for estrus synchronization

One hundred fifty beef heifers and 403 beef cows suckling calves were administered norgestomet implants (8 d) and alfaprostol, a PGF2 alpha analogue, approximately 28 h before implant removal. Thirty hours after implant removal, females were administered either GnRH via injection, GnRH via implantation, or no GnRH. The dosage of GnRH was 250 micrograms, and implants prolong the induced LH surge. Ovulation response, incidence of short cycles, and calving rate were analyzed as a 2 x 2 x 3 completely randomized factorial design with female (heifers and cows), estrous cycles (with or without), and GnRH as the main effects. There were no interactions (P > .10), and because heifers and cows had responses that did not differ (P > .25), they were summarized together. Females with estrous cycles had a higher (P < .05) ovulation response, fewer (P < .01) short luteal phases, and a higher (P < .01) calving rate than females without estrous cycles. Gonadotropin-releasing hormone treatment increased the ovulation response (P < .01) and the calving rate (P < .05), and these responses were not affected (P > .10) by the method of GnRH administration. Based on these data, the increased ovulation response to GnRH may account for 29% of the increase in calving rate observed in the GnRH-treated females. In summary, in norgestomet- and alfaprostol-synchronized females, GnRH enhanced calving rate regardless of how it was administered. This increase was due to more than an increased ovulation rate.     

Effects of space allocation and temperature on periparturient maternal behaviors, steroid concentrations, and piglet growth rates

Preparturient sows were randomly assigned to either a farrowing crate (n = 12) or farrowing pen (n = 12) across cool and hot seasons (with or without drip cooling) to study space allocation and temperature effects on periparturient maternal behaviors, steroid concentrations, and piglet growth rates. Concentrations of estradiol-17 beta (E2 beta), progesterone (P4), and cortisol were quantified in blood collected from surgically implanted vena cava cannulas. Sows were videotaped from 2 h before to 2 h after farrowing. Similar periparturient behaviors were displayed by all sows, regardless of farrowing environment. Sows in pens had lower (P < .05) prepartum P4 concentrations from d -6 to the day preceding farrowing and a reduced (P < .05) piglet birth interval compared with sows in crates (12.95 +/- 1.35 min vs 18.31 +/- 2.21 min, respectively). Additionally, compared with multiparous sows in crates, multiparous sows in pens weaned heavier piglets (P < .05). Estradiol-17 beta concentrations were lower (P < .01) throughout lactation during hot weather for sows with or without drip cooling, averaging 9.30 pg/mL and 8.57 pg/mL, respectively, compared with 18.65 pg/mL for sows during cool weather. This decrease in E2 beta concentration in sows during hot weather was correlated with an extended (P < .05) interval from weaning to first estrus for the sows in hot weather compared to sows during cool weather. Cortisol concentrations decreased progressively during lactation and were not associated with litter weight gains or the interval between weaning and first estrus.     

Synthesis and antitumor evaluation of cis-(1,2-diaminoethane) dichloroplatinum (II) complexes linked to 5- and 6-methyleneuracil and -uridine analogues

OBJECTIVE: To evaluate survival and factors predicting death in bullous pemphigoid. DESIGN: Retrospective analysis of cohort. SETTING: Three referral centers (university hospitals). PATIENTS: Among 237 patients recruited between January 1, 1985, and December 31, 1992, 20 were excluded because of doubtful diagnosis. The 217 remaining patients were 79+/-11 years old (mean+/-SD); 120 were women and 97 were men; and 79% had been treated with oral corticosteroids, 40 to 90 mg/d. INTERVENTIONS: Missing information on follow-up was minimized by letters and/or telephone calls to patients, families, nursing homes, and physicians. MAIN OUTCOME MEASURES: Actuarial survival curve, compared with the expected curve as derived from census data, and evaluation of prognostic factors by comparing initial characteristics between patients alive at 6 months and these who died before that point. RESULTS: Survival curve demonstrated an early increased mortality: 17% at 3 months and 31% at 6 months, mainly from sepsis and cardiovascular diseases. Of the factors related to bullous pemphigoid activity (duration; pruritus; and number and extent of blisters, eosinophilia, and serum antibodies) only generalized pemphigoid was predictive of death in comparison with localized forms. In multivariate analysis, age of 86 years or more (relative risk, 7.1; 95% confidence interval [CI], 2.0-25.4; P < or = .01), poor general condition (relative risk, 8.2; 95% CI, 3.0-22.4; P < or = .001), female sex (relative risk, 2.4; 95% CI, 1.1-5.4; P < or = .05), and generalized disease (relative risk, 4.4; 95% CI, 1.4-13.7; P < or = .01) were associated with increased risks of death at 6 months. CONCLUSION: In this series, generalized bullous pemphigoid had a poor prognosis especially in older patients and those in poor general condition.
