This study investigated the cross-sectional association of job demands (i.e.,
psychological demands) and job resources (i.e., decision latitude, supervisor support,
co-worker support, and extrinsic reward) with job performance. A total of 1,198 workers
(458 males and 740 females) from a manufacturing company in Japan completed a
self-administered questionnaire that included the Job Content Questionnaire, Effort-Reward
Imbalance Questionnaire, World Health Organization Health and Work Performance
Questionnaire, and demographic survey. Hierarchical multiple regression analyses were
conducted. After adjusting for demographic characteristics, decision latitude
(β=0.107, p=0.001) and
extrinsic reward (β=0.158,
p<0.001) were positively and significantly associated
with job performance while supervisor support (β=−0.102,
p=0.002) was negatively and significantly associated
with job performance. On the other hand, psychological demands or co-worker support was
not significantly associated with job performance. These findings suggest that higher
decision latitude and extrinsic reward enhance job performance among Japanese
employees. 相似文献

This study was aimed to investigate the test-retest reliability and validity of a short
version of the New Brief Job Stress Questionnaire (New BJSQ) whose scales have one item
selected from a standard version. Based on the results from an anonymous web-based
questionnaire of occupational health staffs and personnel/labor staffs, we selected
higher-priority scales from the standard version. After selecting one item with highest
item-total correlation coefficient from each scale, a 23-item questionnaire was developed.
A nationally representative survey was administered to Japanese employees
(n=1,633) to examine test-retest reliability and
validity. Most scales (or items) showed modest but adequate levels of test-retest
reliability (r>0.50). Furthermore, job demands and job
resources scales (or items) were associated with mental and physical stress reactions
while job resources scales (or items) were also associated with positive outcomes. These
findings provided a piece of evidence that the short version of the New BJSQ is reliable
and valid. 相似文献

Our current study investigated how workplace social capital (WSC) mediates and moderates
the associations between adverse work characteristics and psychological distress among
Japanese workers. We collected cross-sectional data
(N=9,350) from a baseline survey of an occupational Japanese
cohort study. We focused on individual WSC and considered job demands/control,
effort/reward, and two types (i.e., procedural and interactional) of organizational
justice as work-characteristic variables. We defined psychological distress as a score of
≥5 on the Kessler Psychological Distress Scale (K6 scale). Multivariate logistic
regression analyses predicted a binary variable of psychological distress by individual
WSC and adverse work characteristics, adjusting for individual-level covariates.
Individual WSC mediated the associations between adverse work characteristics and
psychological distress in almost all model specifications. Additionally, individual WSC
moderated the associations of psychological distress with high job demands, high effort,
and low interactional justice when we used a high WSC cutoff point. In contrast,
individual WSC did not moderate such interactions with low job control, reward, or
procedural justice. We concluded that individual WSC mediated the associations between
adverse work characteristics and psychological distress among Japanese workers while
selectively moderating their associations at high levels of WSC. 相似文献

The purpose of this study was to investigate the mechanism of cell death in chondrocytes of the growth plate. In the degenerative chondrocyte zone of the growth plate, apoptotic chondrocytes were defeated by the in situ nick end labelling method, by DNA analysis in agarose gel, and by electron microscopy. The results of the in situ nick end labelling method and the occurrence of a ladder pattern of DNA in agarose gel analysis indicated the activation of endogenous endonucleases, resulting in DNA fragmentation. Electron micrographs showed the early morphological changes associated with apoptosis. This report presents both morphological and biochemical evidence for apoptosis in the terminal hypertrophic chondrocytes of the growth plate. These data suggest that apoptosis of degenerative chondrocytes may play an important role in the control of normal and pathological endochondral ossification. 相似文献

Carotid endarterectomy (CEA) is intended to remove atheromatous plaque by dissecting a plane between the intima and the media (circular medial fibers), but this may not be the optimal dissection plane. The present technique is based on identifying the plane that divides the media from the plaque, so preserving the media on the adventitia as much as possible. This plane is more difficult to find and follow than the easy-to-dissect plane usually located between the media and the adventitia, because the plaque invades the media and so the dividing plane is located within the media. In this prospective observational study, CEA was performed in 22 patients to histologically examine the excised plaques and small samples of the whole arterial wall, and evaluate the clinical outcomes. Plaque had invaded the luminal part of the media in the whole arterial wall sample of 80% of cases. Thin medial layers covering > 80% of the surface of the plaque were found in 16 of 22 plaques (73%). Some atheromatous component was sometimes left in the preserved media, rather than completely removed with the media. No morbidity or mortality had occurred by discharge. Only 1 small ipsilateral infarction (4.5%) and no restenosis of greater than 50% were detected during the mean follow-up period of 7 years. Since the plaque usually invades the media, the optimum dissection plane may be located within the media, dividing it into two layers. The presence of some remnant atheromatous components in the preserved media was not associated with surgical complications or restenosis. 相似文献

Endovascular therapy is strongly recommended for acute cerebral large vessel occlusion (LVO) with an Alberta stroke program early computed tomography score (ASPECTS) ≥6 due to occlusion of the internal carotid artery or M1 segment of the middle cerebral artery. However, the effect of endovascular therapy for patients with a large ischemic core with an ASPECTS ≤5 (0–5) was not established. A multicenter, randomized, open-label, parallel-group trial was conducted to investigate the superiority of endovascular therapy over medical therapy without endovascular therapy for a large ischemic core with ASPECTS (3–5). Patients were randomly assigned to receive endovascular therapy or without endovascular therapy at a ratio of 1:1. The primary outcome was a moderate functional outcome, defined as a modified Rankin scale (mRS; scores ranging from 0 [no symptoms] to 6 [death]) ≤3 after 90 days. The secondary outcomes were defined as ordinal mRS, good functional outcome (mRS ≤2), excellent functional outcome (mRS ≤1), mRS shift analysis after 90 days, and early improvement of neurological findings at 48 hours. A total sample size of 200 was estimated to provide a power of 0.9 with a two-sided alpha of 0.05, for the primary outcome, considering a 15% dropout rate. This randomized clinical trial reported the applicability of endovascular therapy in patients with acute cerebral LVO with a large ischemic core. 相似文献

Effective drug therapy for pulmonary hypertension has not yet been developed. This study was designed to estimate the long-term hemodynamic and histopathological effects of nifedipine on severe pulmonary hypertension using animal models. Injection of one dose of monocrotaline produced subacute pulmonary hypertension in 7 week old Sprague-Dawley rats. Nifedipine (10 mg/kg) was administered intraperitoneally every day. For 5 weeks, bodyweight and hemodynamic parameters were measured, and right ventricle (RV) and left ventricle with septum (LV + S) were weighed separately. Medial thickness of the small pulmonary arterial wall was calculated by Suwa's method. Compared with the control group, the increase in right ventricular systolic pressure, total pulmonary resistance index, weight ratio of RV/(LV + S) and medial hypertrophy in the nifedipine-treated rats were significantly limited without causing systemic hypotension. These results suggest that treatment with nifedipine may also be effective in attenuation of pulmonary hypertension when applied to humans. 相似文献

Although percutaneous transluminal balloon aortic valvuloplasty (PTAV) has been performed for congenital aortic stenosis in infants and children for several years, its efficacy and the associated aortic regurgitation (AR) have not been widely discussed. Percutaneous transluminal balloon aortic valvuloplasty using an Inoue balloon catheter was performed for congenital aortic stenosis in 12 patients (4–16 years old) in this study. The systolic aortic valve pressure gradient ranged from 42 to 111 mmHg before PTAV and became < 50 mmHg immediately after PTAV in 10 cases (83%). Eight of these 10 patients had no increase in the gradient during subsequent observation for a period of 9–40 months. Aortic regurgitation increased immediately after PTAV in nine cases (75%). It increased from grade 1 to grade 2 in eight cases and from grade 1 to grade 3 in one patient; no significant enlargement of the left ventricular end-diastolic diameter and no significant change in the left ventricular end-diastolic pressure (LVEDP) or the cardiac index was observed during follow-up in these patients. There was a correlation between the diameter of the balloon and efficacy; an appropriate diameter was considered to be about 90% of the aortic annular diameter. Changes in the hemodynamic parameter after PTAV with an Inoue balloon were small in most patients and this procedure is considered to be a treatment that should be attempted prior to surgery for congenital aortic stenosis. 相似文献

Transurethral resection is usually performed using an all-in-one drape with a fluid collection pouch, drainage port and hose. Gravity drainage of irrigation fluid through the hose is often hampered, resulting in fluid retention in the pouch. We applied a siphon principle to facilitate fluid drainage by making a U-shaped bend near the distal end of the hose, using an adhesive tape, and hooking the distal end of inverted U shape on the edge of bucket placed on the floor. When the hose is filled with irrigation fluid up to the crest of the siphon, fluid flow driven by atmospheric pressure continues until the pouch is evacuated. Repriming and restarting occur automatically throughout the operation. This simple device has virtually eliminated fluid retention in the pouch and proved to be especially useful in transurethral prostatectomy, which requires a large amount of irrigation fluid. 相似文献

Acute upper gastrointestinal bleeding (UGIB) is a frequent diagnosis prompting hospital admission or complicating another preexisting condition. This report examines the experience of an urban medical center in the utilization of endoscopy and endoscopic hemostasis in the diagnosis and management of UGIB over a four-year period. The first portion of this study examines 562 admissions to a single institution with UGIB. The most common causes of bleeding were acute gastric mucosal lesions (AGML), 24%; esophageal varices (EV), 22%; gastric ulcers, 19%; duodenal ulcers, 14%; Mallory-Weiss tears, 11%; and esophagitis, 3%. Nonoperative treatment was sufficient in the majority of patients (89.5%). Endoscopic therapy was utilized in 144 patients (26%), of whom 12 required a subsequent operation. Fifty-eight patients (10.5%) underwent surgery; however, emergent operations were required in only 2.5% of the patients. Factors correlating with mortality included shock at the time of admission (SBP < 80), transfusion requirements of > 5 U PRBC, and presence of EV (each p < 0.001). The second part of this study examines the effect of thrombogenic sclerotherapy on both short and long-term survival in 101 patients referred with bleeding esophageal varices. Alcoholic cirrhosis was responsible for the majority (88%) of EV, and most patient were Child's C classification (84%). In long-term follow-up, rebleeding was significantly reduced (p = 0.03) in patients compliant with follow-up sclerotherapy. A trend toward decreased mortality was noted in patients compliant with sclerotherapy and in those who avoided further alcohol usage. 相似文献
