Aims:In order for hospitals to work efficiently in a pandemic, it is important to know how a pandemic affects the hospital staff. The aim of the present study was to investigate the psychological impact of the pandemic (H1N1) 2009 on hospital workers and how it was affected by the characteristics of the hospital, gender, age, job and work environment. Methods:In late June 2009, soon after the pandemic had ended in Kobe city, Japan, a questionnaire was distributed consisting of questions on sociodemographic characteristics, 19 stress-related questions and the Impact of Event Scale (IES) to all 3635 employees at three core general hospitals in Kobe. Exploratory factor analysis was applied to the 19 stress-related questions, and this produced four factors for evaluation (anxiety about infection, exhaustion, workload, and feeling of being protected). Multiple regression models were used to evaluate the association of personal characteristics with each score of the four factors and the IES.Results: Valid answers were received from 1625 employees. Workers at a hospital with intense liaison psychiatric services felt less psychological impact. Workers at a hospital that provided staff with information about the pandemic less frequently, felt unprotected. Workers in work environments that had a high risk of infection felt more anxious and more exhausted. The total IES score was higher in workers in high-risk work environments. Conclusions:It is important for hospitals to protect hospital workers during a pandemic and to rapidly share information about the pandemic. Liaison psychiatric services can help to reduce the impact of the pandemic on hospital workers.
BackgroundThe professionalism of hospital workers in Japan was challenged by the pandemic (H1N1) 2009. To maintain hospital function under critical situations such as a pandemic, it is important to understand the factors that increase and decrease the willingness to work. Previous hospital-based studies have examined this question using hypothetical events, but so far it has not been examined in an actual pandemic. Here, we surveyed the factors that influenced the motivation and hesitation of hospital workers to work in Japan soon after the pandemic (H1N1) 2009.MethodsSelf-administered anonymous questionnaires about demographic character and stress factors were distributed to all 3635 employees at three core hospitals in Kobe city, Japan and were collected from June to July, 2009, about one month after the pandemic (H1N1) in Japan.ResultsOf a total of 3635 questionnaires distributed, 1693 (46.7%) valid questionnaires were received. 28.4% (N = 481) of workers had strong motivation and 14.7% (N = 249) had strong hesitation to work. Demographic characters and stress-related questions were categorised into four types according to the odds ratios (OR) of motivation and hesitation to work: some factors increased motivation and lowered hesitation; others increased motivation only; others increased hesitation only and others increased both motivation and hesitation. The strong feeling of being supported by the national and local governments (Multivariate OR: motivation; 3.5; CI 2.2-5.4, hesitation; 0.2; CI 0.1-0.6) and being protected by hospital (Multivariate OR: motivation; 2.8; CI 2.2-3.7, hesitation; 0.5; CI 0.3-0.7) were related to higher motivation and lower hesitation. Here, protection included taking precautions to prevent illness among workers and their families, providing for the care of those who do become ill, reducing malpractice threats, and financial support for families of workers who die on duty. But 94.1% of the respondents answered protection by the national and local government was weak and 79.7% answered protection by the hospital was weak.ConclusionsSome factors have conflicting effects because they increase both motivation and hesitation. Giving workers the feeling that they are being protected by the national and local government and hospital is especially valuable because it increases their motivation and lowers their hesitation to work.
Microcystic stromal tumor (MCST) is a recently described subtype of ovarian tumor characterized by prominent microcystic histologic pattern and diffuse immunoreactivity for CD10 and vimentin. However, its pathobiology, particularly its histogenesis, remains largely unclear. Here, we report 2 cases of ovarian MCST, in which we have performed extensive histologic, immunohistochemical, and genetic investigations to determine its distinct nature among ovarian neoplasms. The patients were 32 and 41 years of age. Both tumors were solid and cystic masses involving the right ovary. Microscopically, tumor cells with generally bland, round-to-ovoid nuclei grew in microcystic, macrocystic, and solid patterns. Intervening thick fibrous stroma was observed. Immunohistochemically, tumor cells were diffusely and strongly positive for CD10, vimentin, and Wilms tumor 1. Furthermore, we detected aberrant nuclear expression of β-catenin protein in both cases. Of interest, mutation analyses revealed the presence of an identical point mutation, c.98C>G, in exon 3 of β-catenin (CTNNB1) in both tumors. This is an oncogenic mutation that causes replacement of serine with cysteine at codon 33, leading to the loss of a phosphorylation site in the β-catenin protein. The results of this study strongly suggest that dysregulation of the Wnt/β-catenin pathway plays a fundamental role in the pathogenesis of ovarian MCST. Finally, by comparing the immunophenotype of MCST with its histologic mimics and other ovarian sex cord-stromal tumors, we were able to identify unique features of MCST and a panel of markers useful in differential diagnosis.
In a series of 32 patients with internal carotid artery occlusion, regional cerebral blood flow (rCBF) and regional cerebral vasoreactivity (rCVR) were measured by xenon-133 single photon emission computed tomography and the acetazolamide test. We evaluated its usefulness in detecting the reduced cerebral perfusion reserve and predicting long-term prognosis. All Type 1 patients (normal rCBF and rCVR) were medically treated and experienced no recurrent ischemic attack. Cerebral hemodynamics remained unchanged. Type 2, 3, and 4 patients underwent superficial temporal artery-middle cerebral artery double anastomosis, if they consented to surgery. All Type 2 (normal rCBF and reduced rCVR) and Type 3 (reduced rCBF and rCVR) patients, who underwent surgery, showed no further ischemic attacks, as well as long-term normalization of rCVR, although long-term rCBF normalization was obtained in only three of seven Type 3 patients. Cerebral hemodynamics remained unchanged in Type 4 patients after surgery. In follow-up periods, major completed stroke occurred in all 3 Type 2 and Type 3 patients who were medically treated. These results suggest that the acetazolamide test is valuable in assessing the cerebral perfusion reserve and predicting long-term prognosis in patients with internal carotid artery occlusion, although further long-term or randomized studies are needed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
