OBJECTIVE: To estimate the association between the number of prior cesarean deliveries and pregnancy outcomes among women with placenta previa. METHODS: Women with a placenta previa and a singleton gestation were identified in a concurrently collected database of cesarean deliveries performed at 19 academic centers during a 4-year period. Maternal and perinatal outcomes were analyzed after stratifying by the number of cesarean deliveries before the index pregnancy. RESULTS: Of the 868 women in the analysis, 488 had no prior cesarean delivery, 252 had one prior cesarean delivery, 76 had two prior cesarean deliveries, and 52 had at least three prior cesarean deliveries. Multiple measures of maternal morbidity (eg, coagulopathy, hysterectomy, pulmonary edema) increased in frequency as the number of prior cesarean deliveries rose. Even one prior cesarean delivery was sufficient to increase the risk of an adverse maternal outcome (a composite of transfusion, hysterectomy, operative injury, coagulopathy, venous thromboembolism, pulmonary edema, or death) from 15% to 23%, which corresponded, in multivariable analysis, to an adjusted odds ratio of 1.9 (95% confidence interval 1.2-2.9). Conversely, gestational age at delivery and adverse perinatal outcome (a composite measure of respiratory distress syndrome, necrotizing enterocolitis, intraventricular hemorrhage grade 3 or 4, seizures, or death) were unrelated to the number of prior cesarean deliveries. CONCLUSION: Among women with a placenta previa, an increasing number of prior cesarean deliveries is associated with increasing maternal, but not perinatal, morbidity. LEVEL OF EVIDENCE: II. 相似文献
OBJECTIVE: To examine maternal and infant outcomes after a vaginal delivery of twin A and a cesarean delivery of twin B, and to identify whether the second twin experienced increased short-term morbidity as part of a combined route of delivery. METHODS: Between January 1, 1999, and December 31, 2000, a prospective cohort study of all cesarean deliveries was conducted at 13 university centers. This secondary analysis was limited to women with twin gestations who experienced labor and underwent cesarean delivery. We compared outcomes of the second twin in women who had vaginal delivery of the first twin and a cesarean delivery of the second twin to those who had cesarean delivery of both twins. RESULTS: One thousand twenty-eight twin pregnancies experienced labor and underwent cesarean delivery; 179 (17%) had a combined vaginal/cesarean delivery. Gestational age at delivery was 34.6 weeks in both groups (P=.97). The rupture of membranes to delivery interval was longer in the combined group (3.2 compared with 2.3 hours, P<.001). Endometritis and culture-proven sepsis in the second twin were more common in the combined group, respectively (n=24, odds ratio 1.6, 95% confidence interval, 1.0-2.7; n=15, odds ratio 1.8, 95% confidence interval, 1.0-3.4). These differences were not significant after logistic regression analysis. There were no statistically significant differences in an arterial cord pH of less than 7.0, Apgar score less than or equal to 3 at 5 minutes, seizures, grade III or IV intraventricular hemorrhage, hypoxic ischemic encephalopathy, or neonatal death. CONCLUSION: Combined twin delivery may be associated with endometritis and neonatal sepsis when compared with a twin delivery where both are delivered by cesarean in twin pregnancies experiencing labor. More serious neonatal sequelae, including hypoxic ischemic encephalopathy and death, were not affected by the route of delivery of the second twin. 相似文献
Fibromyalgia is a complex pain-focused syndrome. Previous studies showed that Cannabis is efficacious in promoting sleep, deepening and lengthening the sleep cycle, and good pain relief (compared with the SSRIs and SNRIs).
Purpose
This study aimed to use the World Health Organization Quality of Life Bref questionnaire (WhoQoL-bref) to characterize the impact of Cannabis Treatment initiation on the quality of life in women suffering from treatment-resistant fibromyalgia.
Methods
A prospective cohort study involving 30 women aged 18–70 years old diagnosed with fibromyalgia, exhausted pharmacological fibromyalgia treatment, and started Cannabis treatment. Pregnant women were excluded. WhoQoL-bref was filled before Cannabis treatment initiation and 1 month following treatment.
Results
Women's average age was 46 years (±5), with a poor general quality of life (1.47 ± 0.63), poor general health (1.47 ± 0.78), pain and discomfort, and dependence on medication (3.77 ± 1.3 and 3.07 ± 1.74, respectively) prior to Cannabis intervention. Cannabis treatment for 30 days showed a marked improvement in general quality of life (1.97 scores, p < 0.01), general health (1.83, p < 0.01), physical health (1.5, p < 0.01), and psychological domain (1.3, p < 0.01). Financial resources and home environment were not influenced by cannabis treatment (p = 0.07, p = 0.31, respectively).
Conclusion
Results suggest a potentially significant role of Cannabis in treatment-resistant Fibromyalgia women. Early Cannabis treatment may result in a beneficial short-term effect on the quality of life through its influence on pain, sleep, and physical and psychological domains. Further studies are still indicated to understand this potential and its long-term beneficial impact. 相似文献
Objective. To measure the anatomic and physiologic changes in the synovium of patients with active rheumatoid arthritis (RA) before and after the initiation of treatment with low-dose systemic glucocorticoids and methotrexate (MTX). Methods. Two patients with RA with active synovitis involving the carpus were evaluated by imaging parameters at baseline and again after 14 weeks (of treatment with low-dose prednisone and MTX). Standard clinical parameters, laboratory measurements, and contrast-enhanced magnetic resonance imaging (MRI) (synovial volume estimate) and positron emission tomography (PET) with 18F-fluoro-2-deoxyglucose (18-FDG) (synovial metabolism estimate) were performed. Results. Compared with baseline, standard clinical parameters (i.e., joint count, joint index, morning stiffness, global assessments of arthritis activity, and erythrocyte sedimentation rate) improved dramatically in both patients after treatment with low-dose prednisone and MTX. In concert with this trend, the synovial volume of the affected wrist was reduced by 60%, and 76% and the metabolism of 18-FDG was reduced by 66% and 69% in the 2 patients. Conclusion. These preliminary observations indicate that a volumetric estimate of inflamed synovium (using contrast-enhanced MRI) and quantification of synovial deoxyglucose metabolism (using PET) are technically feasible and, in the 2 reported cases, correlate well with standard outcome measures. These imaging modalities may provide new objective parameters to determine RA disease activity and effectiveness of antirheumatic medications; however, the potential clinical utility of these measures remains to be defined. 相似文献
Wildman (2021), who identifies “a clear association between income inequality [measured by the Gini coefficient] and COVID-19 cases and deaths,” concludes that “a goal of government should be to reduce [income] inequalities and [thereby] improve [the COVID-19 outcomes /] underlying health of their populations.” In this Comment, we argue that reducing the Gini coefficient of the income distribution of a population need not weaken the population’s social stress. It is this stress which is a source of adverse health outcomes of the population. Because a measure of this stress is a component of the Gini coefficient, reducing the coefficient can leave the measure as is, or even increase the measure.
Objective. To determine the serum autoantibody profile in an adult patient with systemic lupus erythematosus manifested by complete heart block (CHB) and seizures, and to investigate the source of autoantibodies found in the patient's cerebrospinal fluid (CSF). Methods. The serum and CSF autoantibody profiles were determined by serologic testing and Western blot studies. An antibody activity index was devised to determine the source of the autoantibodies found in the CSF. Results. The patient's serum contained anti-SS-A (52 kd and 60 kd), anti-SS-B, anti-U1 RNP, and anti-Sm autoantibodies. Studies of her CSF, however, revealed only anti-SS-A and anti-SS-B autoantibodies, with a high antibody activity index. Conclusion. The finding of anti-SS-A (52 kd and 60 kd) and anti-SS-B autoantibodies was similar to reported findings in congenital CHB. Intrathecal synthesis of anti-SS-A and anti-SS-B was the source of autoantibodies found in the CSF. This patient's symptoms may be pathophysiologically linked to an immune reaction between the anti-SS-A and anti-SS-B autoantibodies and neural tissue in the brain and heart. 相似文献
