We investigated the associations of surgeons' emotional intelligence and surgeons' empathy with patient-surgeon relationships, patient perceptions of their health, and patient satisfaction before and after surgical procedures. We used multi-source approaches to survey 50 surgeons and their 549 outpatients during initial and follow-up visits. Surgeons' emotional intelligence had a positive effect (r = .45; p < .001) on patient-rated patient-surgeon relationships. Patient-surgeon relationships had a positive impact on patient satisfaction before surgery (r = .95; p < .001). Surgeon empathy did not have an effect on patient-surgeon relationships or patient satisfaction prior to surgery. But after surgery, surgeon empathy appeared to have a significantly positive and indirect effect on patient satisfaction through the mediating effect of patients' self-reported health status (r = .21; p < .001). Our study showed that long-term patient satisfaction with their surgeons is affected less by emotional intelligence than by empathy. Furthermore, empathy indirectly affects patient satisfaction through its positive effect on health outcomes, which have a direct effect on patients' satisfaction with their surgeons.
The effect of allantoin, an active component of yam, on plasma glucose of streptozotocin-induced diabetic rats (STZ-diabetic rats) is investigated. Allantoin decreased plasma glucose levels in a dose-related manner, which was reduced by pretreatment with naloxone or naloxonazine. A concomitant increase in plasma β-endorphin, detected by enzyme-linked immunosorbent assay, was observed. Moreover, allantoin enhanced β-endorphin release from the isolated adrenal medulla of STZ-diabetic rat in a dose-related manner. However, its plasma glucose lowering action was reduced but not totally abolished by bilateral adrenalectomy. Furthermore, allantoin directly increased radioactive glucose uptake in isolated skeletal muscle, and repeated administration for 3 days increased GLUT4 mRNA and protein levels in muscle. This effect was markedly reduced in STZ-diabetic rats with bilateral adrenalectomy. This study suggests that allantoin increases GLUT4 gene expression in muscle by increasing β-endorphin secretion from the adrenal gland in STZ-diabetic rats.
The clinical manifestations of acute Q fever hepatitis differ little in patients with and patients without underlying viral hepatitis, and replication of hepatitis virus is not influenced by acute Q fever hepatitis.
1. Sinomenine is an alkaloid with a wide range of pharmacological actions. In the present study, we investigated the effect of sinomenine on blood pressure and its possible mechanisms of action. 2. Spontaneously hypertensive rats (SHR) and normotensive Wistar-Kyoto (WKY) rats were given intraperitoneal injections of sinomenine. At 30 min, 2.5-10 mg/kg sinomenine decreased systolic blood pressure (SBP) in a dose-dependent manner in SHR, but had no effect on the SBP in WKY rats. 3. The vascular effect of sinomenine was then examined in aortic rings isolated from Wistar rats. Sinomenine (0.1-10 micromol/L) produced concentration-dependent relaxation in aortic rings precontracted with phenylephrine (10 nmol/L) or KCl (40 mmol/L). Glibenclamide (1-100 micromol/L), a specific inhibitor of ATP-sensitive K(+) channels attenuated the sinomenine-induced relaxation, but this effect was not observed when inhibitors of other types of K(+) channels were used. 4. We further investigated the effects of sinomenine on changes in intracellular Ca(2+) concentrations ([Ca(2+)](i)) in cultured aortic smooth muscle (A7r5) cells by using the Ca(2+)-sensitive dye fura-2 as an indicator. Sinomenine, over the concentration range 0.1-10 micromol/L, decreased the increases in [Ca(2+)](i) elicited by phenylephrine (1 micromol/L) or KCl (40 mmol/L) in a concentration-dependent manner. Glibenclamide (1-100 micromol/L) abolished the effects of sinomenine. 5. In conclusion, sinomenine causes vascular relaxation by opening ATP-sensitive K(+) channels, thus decreasing [Ca(2+)](i).
Compared with OM, LM was found to be associated with shorter surgical time and less blood loss, but there was no difference in the rate of complications or recurrence between the 2 groups.
Esophageal reconstruction can be performed with skin or bowel flaps. The choice of flap remains controversial, as the long-term outcomes of skin flaps cannot always be assessed in patients with limited life expectancies due to advanced malignancy, unlike the pediatric and benign cases which have had esophageal reconstruction using bowel flaps. We report the long-term clinical and histopathological outcomes in a series of 45 cases repaired with combined skin and bowel flaps.Four patients developed symptomatic strictures after corrosive esophageal injuries were repaired with a combination of a tubed free radial forearm fasciocutaneous flap and a pedicled bowel flap. On average, 24 years had passed since uneventful initial esophageal reconstructions. Barium esophagograms were obtained in all cases and pathological examination was performed upon all surgical specimens.The cutaneous portions of the reconstructed esophagus exhibited a variety of findings on barium examination. Each of the 4 cases developed an esophagocutaneous fistula after revision; an average of 4 surgeries was required to close these fistulae. The inner surfaces of the portion of esophagus repaired with skin flaps showed extensive ulceration, polypoid lesions, and fibrosis. Pathology specimens from skin flaps showed extensive acute and chronic inflammation, microabscesses, fibrosis, and acanthosis, with depletion and degeneration of the pilosebaceous units. By contrast, adjacent parts of the esophagus repaired with bowel were widely patent with normal appearing mucosa.Our findings indicate that a bowel flap is durable with good tolerance to gastrointestinal content over long periods, whereas skin flaps often developed morphological changes and could not maintain long-term esophageal function without eventual stricture and dysphagia. We therefore recommend use of bowel flaps for esophageal reconstruction in patients with long life expectancy.
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.
