From Jan 1, 1978 through Dec 31, 1983, 64 patients with epithelial ovarian tumors, frankly malignant or borderline, were managed at one institution. Nineteen patients (29.7%) were under age 40. The youngest patient was 19 years old. Nulliparity was present in 32% of this group of patients. Of these young patients, 58% had borderline epithelial tumors, compared to 13% of patients over 40 years of age. Twenty-one percent of the young patients were initially managed by unilateral adnexal surgery. The overall cumulative actuarial survival rate of all young patients was 93%. Young patients with epithelial ovarian tumors tend to have earlier grades of epithelial neoplasms, and survival is better than that reported for older patients with similar tumors.  相似文献

Monkeypox is a rare zoonotic disease caused by infection with the monkeypox virus. The disease can result in flu-like symptoms, fever, and a persistent rash. The disease is currently spreading throughout the world and prevention and treatment efforts are being intensified. Although there is no treatment that has been specifically approved for monkeypox virus infection, infected patients may benefit from using certain antiviral medications that are typically prescribed for the treatment of smallpox. The drugs are tecovirimat, brincidofovir, and cidofovir, all of which are currently in short supply due to the spread of the monkeypox virus. Resistance is also a concern, as widespread replication of the monkeypox virus can lead to mutations that produce monkeypox viruses that are resistant to the currently available treatments. This article discusses monkeypox disease, potential drug targets, and management strategies to overcome monkeypox disease. With the discovery of new drugs, it is hoped that the problem of insufficient drugs will be resolved, and it is not anticipated that drug resistance will become a major issue in the near future.  相似文献

This study investigated the use of EMG biofeedback to simulate weakened rectus femorii and gastrocnemii muscles during the performance of a lifting task. Eight healthy women performed 15 kg free-style lifts from floor level. Three conditions were tested: unconstrained lifting, lifting with rectus femorii activity volitionally limited bilaterally through EMG biofeedback to less than 45% of maximal EMG activity, and lifting with the gastrocnemii limited to a similar level. Limiting leg muscle activity through biofeedback led to an alteration of lifting strategy, with resulting performance variables (joint angles and torques, angular velocities, center of pressure excursion, and segment coordination) comparing favorably with those from lifting trials performed by six women with moderate leg muscle weaknesses. The data indicate that EMG biofeedback can be used to simulate the effects of leg muscle weakness during these lifts, providing a new tool to study the biomechanics of muscle weakness.  相似文献

OBJECTIVE: To assess invited resident applicants' views of the feasibility and acceptability of a point-and-click online interview scheduler. METHODS: An online program was created for invited applicants to schedule themselves. The program presented the invitees with a series of interview dates with available slots for which they could click and receive immediate confirmation of their selected date. The majority of the invitees were asked to schedule online. These invitees received a brief survey to assess their views of the online scheduler. RESULTS: Eighty-three applicants were invited by e-mail for a resident interview, 71 of whom were offered the online scheduler. Of these 100% booked themselves online within 3-4 days of invitation. After three e-mail reminders 100% of the invitees completed the survey. Sixty-five of the 71 (92%, 95% confidence interval [CI] 85.4-98.6) said they liked the scheduling program, and most (77%, 95% CI 67.2-86.8) preferred to book online rather than telephone or e-mail. Eighty percent (95% CI 70.7-89.3) found the online scheduler easier to use. Overall, 72% (95% CI 60.5-81.6) felt that having an on-line scheduler did not affect their opinion of the quality of the program. Invitees in favor of the scheduler liked the convenience of anytime scheduling, the immediate confirmation, a quick view of available dates and times, and the ability to schedule without depending on someone else. CONCLUSION: Our online scheduler proved to be easy to use, eliminated phone calls with applicants, and satisfied most of the invitees.  相似文献

A large increase in the use of kidneys from donation after circulatory death (DCD) donors prompted us to examine the impact of donor type on the incidence of ureteric complications (UCs; ureteric stenosis, urinary leak) after kidney transplantation. We studied 1072 consecutive kidney transplants (DCD n=494, live donor [LD] n=273, donation after brain death [DBD] n=305) performed during 2008‐2014. Overall, there was a low incidence of UCs after kidney transplantation (3.5%). Despite a trend toward higher incidence of UCs in DCD (n=22, 4.5%) compared to LD (n=10, 3.7%) and DBD (n=5, 1.6%) kidney transplants, donor type was not a significant risk factor for UCs in multivariate analysis (DCD vs DBD HR: 2.33, 95% CI: 0.77‐7.03, P=.13). There was no association between the incidence of UCs and donor, recipient, or transplant‐related characteristics. Management involved surgical reconstruction in the majority of cases, with restenosis in 2.7% requiring re‐operation. No grafts were lost secondary to UCs. Despite a significant increase in the number of kidney transplants from DCD donors, the incidence of UCs remains low. When ureteric complications do occur, they can be treated successfully with surgical reconstruction with no adverse effect on graft or patient survival.  相似文献

Negative and stigmatizing beliefs regarding mental health nursing discredit the valuable contributions of mental health nurses, but more importantly, these beliefs discredit the needs of people who access mental health care. The stigma associated with mental health nursing, however, has received little attention in the literature. In this article, the author explores the stigma associated with mental health nursing from a critical lens. Recommendations are proposed to address the stigma associated with mental health nursing and mental illness, concurrently, within nursing education.  相似文献
