Public Attitudes Toward Incentives for Organ Donation: A National Study of Different Racial/Ethnic and Income Groups

Attitudes toward monetary and nonmonetary incentives for living (LD) and deceased donation (DD) among the U.S. general public and different racial/ethnic and income groups have not been systematically studied. We studied attitudes via a telephone questionnaire administered to persons aged 18-75 in the continental United States. Among 845 participants (85% of randomized households), less than one-fifth participants were in favor of incentives for DD (range 7-17%). Most persons were in favor of reimbursement of medical costs (91%), paid leave (84%) and priority on the waiting list (59%) for LD. African Americans and Hispanics were more likely than Whites to be in favor of some incentives for DD. African Americans were more likely than Whites to be in favor of monetary incentives for LD. Whites with incomes less than $20 000 were more likely than Whites with greater incomes to be in favor of reimbursement for deceased donors' funeral expenses or medical expenses. The U.S. public is not generally supportive of incentives for DD, but is supportive of limited incentives for LD. Racial/ethnic minorities are more supportive than Whites of some incentives. Persons with low income may be more accepting of certain monetary incentives.     

The hazards to practitioners of obstetric and gynecological ultrasound.

OBJECTIVES: To investigate the specific complaints of physicians and technicians performing obstetric and gynecological ultrasound. METHODS: This was a cross-sectional retrospective survey. Questionnaires were distributed to members of the Israeli Society of Gynecological Ultrasound, including questions on gender and profession, number and type of scans performed, pain related to profession and any therapy undergone. Statistical analysis included chi-square or Fisher's exact test, Student's t-test, Pearson's correlation coefficient and logistic regression. RESULTS: Joint pain was reported by 51.7% (30/58) of the technicians compared with 25.3% (19/75) of the physicians (P = 0.002). It was more common in females than in males (P = 0.05) and it was more common among those who performed transabdominal sonography more frequently than they did transvaginal sonography (P = 0.004). There was a significant association between performing transabdominal ultrasound and back pain (P = 0.05). Although females reported pain more frequently, the rate of surgical procedures was higher among males (P < 0.05). CONCLUSIONS: A technician is 3.5 times more likely to report joint pain than is a physician. Transabdominal sonography is a risk for both joint and back pain. There may be gender differences in pain perception.     

Reciprocal relationships between general (Propofol) anesthesia and circadian time in rats.

Several common postdischarge symptoms, such as sleep disorders, headache, drowsiness or general malaise, evoke disturbances of circadian rhythms due to jet lag (ie crossing time zones) or shift work rotation. Considering that general anesthesia is associated with numerous effects on the central nervous system, we hypothesized that it may also act on the circadian timing system. We first determined the effects of the circadian timing on general anesthesia. We observed that identical doses of propofol showed marked circadian fluctuations in duration of effects, with a peak at the middle of the resting period (ie 7 h after lights on). Then, we examined the effects of general anesthesia on circadian timing, by analysing stable free-running circadian rhythms (ie in constant environmental conditions), an experimental approach used widely in circadian biology. Free-running rats were housed in constant darkness and temperature to assess possible phase-shifting effects of propofol anesthesia according to the time of the day. When administered around (+/-2 h) the daily rest/activity transition point, a 30-min propofol anesthesia induced a 1-h phase advance in the free-running rest-activity rhythm, while anesthesia had no significant resetting effect at other times of the day. Anesthesia-induced hypothermia was not correlated with the phase-shifting effects of propofol anesthesia. From our results, anesthesia itself can reset circadian timing, and acts as a synchronizing cue for the circadian clock.     

Positron emission tomography using 18F-fluorodeoxyglucose in the management of nonsmall cell lung cancers in 2006]

Technological progress and numerous published studies allow to estimate the best place of the 18F-fluorodeoxyglucose positron emission tomography, a real functional metabolic imagery, in the clinical and therapeutic strategy of non small cell lung cancers.     

Accelerated partial breast irradiation: a concept to individualize treatment in breast cancer]

Whole breast irradiation delivering an equivalent dose of 50 Gy in 5 weeks, followed by a 10 to 16 Gy-boost to the tumor bed is the standard of care after breast-conserving surgery for early-breast cancer. Accelerated partial breast irradiation (APBI) is currently under investigations in large multi-institutional, prospective, randomized trials to objectively address the critical endpoints of treatment efficacy, toxicity and cosmesis. Patient's selection for this new approach is crucial to individualise treatments and define the subgroups of patients who will really benefit from APBI in terms of quality of life without decreasing long-term results of the disease control and cosmesis. In this review, we will discuss the patients' profiles selection for APBI regarding their general and tumor criteria. The differences between APBI techniques either performed intra or post operatively will be also discussed.
