Wir beschreiben den Krankheitsverlauf einer 36-j?hrigen Frau mit unbehandelter Aortenisthmusstenose und offenem Ductus Botalli, die aufgrund einer ausgepr?gten linksventrikul?ren Dysfunktion eine therapierefrakt?re Herzinsuffizienz entwickelte. Nach operativer Korrektur der Aortenisthmusstenose und Ductusresektion normalisierte sich die linksventrikul?re Pumpfunktion, sodass davon ausgegangen werden kann, dass auch schwere linksventrikul?re Dysfunktionen auf dem Boden langj?hriger Druck- und Volumenbelastung durch angeborene Herzfehler nach operativer Korrektur reversibel sein k?nnen. 相似文献
Objective: To determine the association between mode of delivery and maternal complications in patients with severe preeclampsia.
Methods: A prospective cohort study was conducted with 500 pregnant women with severe preeclampsia. The mode of delivery, vaginal or caesarean section, was considered the exposure, while the postpartum maternal complications and severe maternal morbidity were the outcomes. Logistic regression analysis was performed to determine the adjusted risk and 95% confidence intervals (95% CI) of maternal morbidity.
Results: Labour was spontaneous in 22.0% and induced in 28.2%, while 49.8% had an elective caesarean section. Ninety-five (67.4%) of the patients in whom labour was induced delivered vaginally. Total Caesarean rate was 68.2%. The risk of severe maternal morbidity was significantly greater in patients submitted to Caesarean section (54.0% versus 32.7%) irrespective of the presence of labour. Factors that remained associated with severe maternal morbidity following multivariate analysis were a diagnosis of HELLP syndrome after delivery (OR?=?3.73; 95% CI: 1.55–9.88) and having a caesarean (OR?=?1.91; 95% CI: 1.52–4.57).
Conclusions: Caesareans are often performed in patients with severe preeclampsia and are associated with significant postpartum maternal morbidity. Induction of labour should be considered a feasible option in these patients. 相似文献
Overexposure to manganese (Mn) has been known to induce nitrosative stress. The dysregulation of autophagy has implicated in nitric oxide (NO) bioactivity alterations. However, the mechanism of Mn‐induced autophagic dysregulation is unclear. The protein of Bcl‐2 was considered as a key role that could participate to the autophagy signaling regulation. To further explore whether S‐nitrosylation of Bcl‐2 involved in Mn‐induced autophagy dysregulation, we treated human neuroblastoma (SH‐SY5Y) cells with Mn and pretreated cells with 1400 W, a selective iNOS inhibitor. After cells were treated with 400 μM Mn for 24 h, there were significant increases in production of NO, inducible NO synthase (iNOS) activity, the mRNA and protein expressions of iNOS. Interestingly, autophagy was activated after cells were treated with Mn for 0–12 h; while the degradation process of autophagy‐lysosome pathway was blocked after cells were treated with Mn for 24 h. Moreover, S‐nitrosylated JNK and Bcl‐2 also increased and phospho‐JNK and phospho‐Bcl‐2 reduced in Mn‐treated cells. Then, the affinity between Bcl‐2 and Beclin‐1 increased significantly in Mn‐treated cells. We used the 1400 W to neutralize Mn‐induced nitrosative stress. The results showed that S‐nitrosylated JNK and Bcl‐2 reduced while their phosphorylation were recovered to some extent. The findings revealed that NO‐mediated S‐nitrosylation of Bcl‐2 directly affected the interaction between Beclin‐1 and Bcl‐2 leading to autophagy inhibition. 相似文献
Context: (-)-α-Bisabolol (BISA) is a sesquiterpene alcohol widely used as scent in cosmetic preparations, perfumes, shampoos, toilet soaps and other toiletries with potential for use in the pharmaceutical area.Objective: To evaluate the corneal antinociceptive efficacy of BISA and to analyze the best solubilizing agent.Materials and methods: Acute corneal nociception was induced by the local application of hypertonic saline (5 M NaCl; 20?μL) to the corneal surface of Swiss mice (n?=?8/group) 60?min after topical treatment with solutions or ointment containing BISA (50–200?mg/mL). The number of eye wipes performed with the ipsilateral forepaw was counted for a period of 30?s. Control groups (vehicles) were included.Results: BISA (50, 100 or 200?mg/mL) solubilized with Tween 80 did not reduce the number of eye wipes. Animals treated with the ointment (BISA 50, 100 or 200?mg/mL; p?0.001), as well the solution containing propylene glycol (BISA 100?mg/mL; p?0.05), showed significant reduction in the number of nociceptive behaviours. Solutions containing propylene glycol and isopropyl myristate had no effects.Discussion and conclusion: BISA possess corneal antinociceptive activity. Although the ointment presented antinociceptive effect, it is concluded that BISA when associated with propylene glycol has better potential for corneal nociceptive pain since it is more comfortable to use, leading to greater acceptance by patients. 相似文献
The goal of this paper is to assess the frequency of depression symptoms among Brazilian immigrants living in Massachusetts, the second largest Brazilian immigrant population in the United States, and to identify correlates of depression. A convenience sample of Brazilian immigrants aged 18 or older residing in Massachusetts was used. Data were collected from December 2013 to March 2014, in the Consulate General of Brazil in Boston and in three religious events, using a structure questionnaire and the Center for Epidemiological Studies Depression Scale (CES-D). Depression symptoms were observed in 35.3% of the respondents, with equal distribution by sex. Correlates of depression were low income, being single, poor English proficiency, and poor self-perception of health. These results suggest a need for community outreach, sensitization, and counseling, in Portuguese and adapted to the culture of Brazilian immigrants. 相似文献
