Sleep disturbance and fatigue are frequent complaints during pregnancy and postpartum. We assessed the effectiveness of Lavender cream and footbath on sleep quality and fatigue in pregnancy and postpartum. In this trial, 141 women with sleep disturbance at 25–28 weeks gestation were recruited from public health centers in Tabriz, Iran, from May 2013 until January 2014 and randomized into one of three groups receiving: Lavender and footbath, Lavender alone, or placebo cream. Sleep quality was assessed using the Pittsburgh sleep quality index at the 4th and 8th weeks after intervention and the 6th week postpartum. Fatigue was assessed with the multidimensional assessment of fatigue scale at the 6th week after intervention and the 6th week postpartum. Repeated measures ANOVA and ANCOVA were used. Compared with the placebo group, the global sleep quality score post-intervention in pregnancy and the postpartum were significantly lower in the Lavender and footbath and the Lavender cream only groups. Fatigue in both intervention groups was significantly improved only at the 6th week postpartum. No statistically significant differences were observed between the two intervention groups. Lavender cream with or without footbath may improve sleep quality in pregnancy and postpartum.  相似文献

OBJECTIVE: Moderate to severe irreversible mitral regurgitation secondary to myocardial infarction is an independent risk factor for reduced long-term survival. Late effects of correction of mitral incompetence concomitant with coronary artery bypass grafting (CABG) are less well known and the choice of mitral valve procedure is still debated. METHODS: From 1988 to 1998, 93 consecutive patients (mean age 63+/-9 years) were treated for moderate to severe irreversible mitral regurgitation secondary to myocardial infarction; 84 were in NYHA functional class III-IV and 19 were in cardiogenic shock. Thirty-seven patients underwent emergency surgery. Perioperative intraaortic balloon pump (IABP) was necessary in 33 patients. Follow-up ranged from 6 months to 12 years (mean 51 months+/-41). RESULTS: Mitral valve was repaired in 30 patients and replaced in 63. Replacement was preferably performed in patients with major displacement of papillary muscle and in patients with acute papillary muscle rupture. CABG (3.4 distal anastomoses) was performed in all patients and was complete in 92%. Early mortality was 15% (14/93). Multivariable analysis identified need for IABP (P=0.005) and COPD (P=0.02) as risk factors for early death. Emergency surgery had only a trend (P=0.15) for increased mortality; age, low ejection fraction, repair vs. replacement had no influence. Actuarial survival rates at 1, 5 and 10 years were 81, 65 and 56%, respectively. Late survival was similar in patients with replacement or repair (P=0.46). At last follow-up, all but one patient were in NYHA functional class I or II. CONCLUSIONS: Combined mitral valve procedure and myocardial revascularization, as complete as possible, for moderate to severe mitral regurgitation secondary to myocardial infarction achieve satisfactory early and late outcome despite the increased operative mortality. Acute papillary muscle rupture, severe restriction of the mitral valve by major displacement of the papillary muscle are better managed by valve replacement.  相似文献

Older age, prior transplantation, pulmonary hypertension, and mechanical support are commonly seen in current potential cardiac transplant recipients. Transplants in 436 consecutive adult patients from 1994 to 1999 were reviewed. There were 251 using standard donors in 243 patients (age range 18-69 years). To emphasize recipient risk, 185 patients who received a nonstandard donor were excluded from analysis. The indications for transplant were ischemic heart disease (n = 123, 47%), dilated cardiomyopathy (n = 82, 32%), and others (n=56, 21%). One hundred and forty-nine (57%) recipients were listed as status I; 5 and 6% were supported with an intra-aortic balloon and an assist device, respectively. The 30-d survival and survival to discharge were 94.7 and 92.7%, respectively; 1-year survival was 89.1%. Causes of early death were graft failure (n = 6), infection (n = 4), stroke (n = 4), multiorgan failure (n = 3) and rejection (n = 2). Predictors were balloon pump use alone (OR= 11.4, p =0.002), pulmonary vascular resistance > 4 Wood units (OR = 5.7, p = 0.007), pretransplant creatinine > 2.0 mg/dL (OR = 6.9, p = 0.004) and female donor (OR = 8.3, p = 0.002). Recipient age and previous surgery did not affect short-term survival. Heart transplantation in the current era consistently offers excellent early and 1-year survival for well-selected recipients receiving standard donors. Early mortality tends to reflect graft failure while hospital mortality may be more indicative of recipient selection.  相似文献

The role of CC chemokine receptor 5 (CCR5) in islet allograft rejection   总被引:6,自引:0,他引:6  
Chemokines are important regulators in the development, differentiation, and anatomic location of leukocytes. CC chemokine receptor 5 (CCR5) is expressed preferentially by CD4(+) T helper 1 (Th1) cells. We sought to determine the role of CCR5 in islet allograft rejection in a streptozotocin-induced diabetic mouse model. BALB/c islet allografts transplanted into CCR5(-/-) (C57BL/6) recipients survived significantly longer (mean survival time, 38 +/- 8 days) compared with those transplanted into wild-type control mice (10 +/- 2 days; P < 0.0001). Twenty percent of islet allografts in CCR5(-/-) animals without other treatment survived >90 days. In CCR5(-/-) mice, intragraft mRNA expression of interleukin-4 and -5 was increased, whereas that of interferon-gamma was decreased, corresponding to a Th2 pattern of T-cell activation in the target tissues compared with a Th1 pattern observed in controls. A similar Th2 response pattern was also observed in the periphery (splenocytes responding to donor cells) by enzyme-linked immunosorbent spot assay. We conclude that CCR5 plays an important role in orchestrating the Th1 immune response leading to islet allograft rejection. Targeting this chemokine receptor, therefore, may provide a clinically useful strategy to prevent islet allograft rejection.  相似文献

BACKGROUND: The long-term outcome after resection of hepatocellular carcinoma (HCC) is influenced by parameters related to the tumor and the underlying liver disease. However, the extent of the resection, which can be limited or anatomical (including the tumor and its portal territory), is controversial. METHODS: Among 64 Child-Pugh A patients with cirrhosis who underwent curative liver resection for small HCC (< or = 4 cm) between 1990 and 1996, 34 patients underwent limited resection with a margin width of at least 1 cm, and 30 patients underwent anatomic resection of at least 1 liver segment with complete removal of the portal area containing the tumor. The 2 groups were comparable in terms of epidemiologic and pathologic parameters. The major end points were: (1) in-hospital mortality and morbidity; (2) overall and disease-free survival; and (3) rate and topography of recurrence. RESULTS: The 30-day mortality (6% vs 7%) and morbidity (52% vs 47%) rates after limited and anatomic liver resection were not statistically different. The 5- and 8-year overall survival rates after limited versus anatomic resection were, respectively, 35% versus 54% (P <.05) and 6% versus 45% (P <.05). The 5- and 8-year disease-free survival rates were, respectively, 26% versus 45% and 0% versus 21% (P <.05). Local recurrence was more frequently observed after limited resections than after anatomic resections (50% vs 10%, P <.05). CONCLUSIONS: In patients with cirrhosis and a small HCC, anatomic resection achieves better disease-free survival than limited resection without increasing the postoperative risk. Therefore, anatomical resection should be the treatment of choice and considered as the reference surgical treatment compared with other treatments.  相似文献

BACKGROUND: Differences can exist in terms of physiology and morphology of blood vessels on the basis of gender. Radial artery is now considered to be the second choice for coronary artery bypass grafting. However, there is a lack of comparative studies on the function and morphometery of radial arteries in female and male patients. METHODS: Radial arteries from 9 female and 9 male patients undergoing coronary artery bypass grafting were used to compare the effects of vasoconstrictors, noradrenaline and 5-hydroxytryptamine, as well as the influence of endothelium-dependent (with methacholine) and endothelium-independent (with sodium nitroprusside) relaxations. Furthermore, morphomteric measurements of smooth muscle thickness, lumen perimeter, lumen area, and intima area (including plaque) of distal radial arteries from female and male patients were also made. RESULTS: Radial arteries from female patients when compared to male patients were significantly more sensitive to the actions of noradrenaline, and somewhat more sensitive towards the actions of 5-hydroxytryptamine. However, no significant differences were found between the relaxant effects of methacholine in radial arteries of female and male patients. In contrast, radial arteries from female patients when compared to male patients were significantly less sensitive to the relaxant effects of sodium nitroprusside. Morphometric measurements of blood vessels from female and male patients revealed that vessels obtained from female patients had a smaller lumen area and perimeter than vessels from male patients. In contrast, there were no significant differences between tunica intima area (including plaque area) or smooth muscle thickness in radial arteries of female patients when compared to male patients. However, the radial arteries from female patients had a significantly greater ratio of tunica intima area (including plaque) to lumen area when compared with radial arteries from male patients. CONCLUSIONS: Differences exist between the functional behavior and morphometery of radial arteries of female and male patients. It is possible that postbypass, radial artery graft may show different characteristics in female versus male patients.  相似文献

Background

After a brain biopsy, the genetic analysis can fail because of insufficient material, extensive tumor necrosis, and formalin fixation under conditions that adversely affected the quality of the DNA or because the assay result was indeterminant. The freezing of fresh tumor tissue at surgery could greatly improve the success of DNA extraction and methyl guanine methyl transferase (MGMT) promoter methylation testing. The concentration of the DNA samples can also be improved from a withdrawal in an area with a high probability of neoplastic cells.

Methods

The present study reports the results of ten frameless image-guided intracranial needle biopsies from April 2008 until February 2009, among a total of 28 frameless neuronavigation brain biopsy performed from May 2007 to February 2009. The protocol sampling provided withdrawal specimens correlated with neuroimaging characteristics of the lesions. The molecular determination of MGMT promoter was assessed with the nested methylation-specific polymerase chain reaction on fresh or cryopreserved needle bioptic tissue.

Results

The genetic characterization was feasible in all the bioptic samples. The MGMT promoter was methylated in six patients, including a brain infection. The image-guided trajectory of the biopsy and the intraoperative frozen section increased the diagnostic yield.

Conclusions

To the best of the authors' knowledge, this is the first report with the MGMT promoter status analysis on needle bioptic fresh tissue. In the future, the availability of the molecular genetic characterization of a brain tumor before open surgery will provide important information for the optimal treatment.  相似文献
