不同容量小水囊用于足月妊娠促宫颈成熟的临床效果分析

目的探讨不同容量小水囊对足月妊娠产妇促宫颈成熟的效果。方法选择2013年1月—2015年1月收治的150例足月妊娠并进行引产产妇,按随机数字表法平均分为3组,每组各50例,30 ml小水囊组(A组)、80ml小水囊组(B组)及150 ml小水囊组(C组)。比较3组产妇引产前后宫颈评分情况、促宫颈成熟效果、产妇分娩结局及新生儿结局。结果 B组产妇促宫颈成熟有效率为96.0%(48/50),C组为98.0%(49/50),均明显高于A组的84.0%(42/50),差异具有统计学意义(χ~2=3.90、4.03,P<0.05);B组及C组产妇的产后Bishop评分明显高于A组,而引产至临产时间及第一产程时间均明显短于A组(P=3.96、3.85、4.05,P<0.05);B组与C组经阴道分娩率分别为90.0%(45/50)及92.0%(46/50),均明显高于A组的54.0%(27/50),比较差异具有统计学意义(χ~2=4.52,P<0.05),而B组与C组比较差异无统计学意义(P>0.05);3组产妇产后出血量、3组新生儿Apgar评分、新生儿体质量比较差异无统计学意义(F=1.24、0.47、0.37,P>0.05),而C组新生儿窒息率、脐带脱垂率明显高于A组及B组,比较差异具有统计学意义(P<0.05)。结论 80 ml小水囊应用于足月妊娠产妇的促宫颈成熟效果好,对产妇及新生儿均不会造成严重不良反应,值得临床推广应用。

Changes in Weight Associated With Telotristat Ethyl in the Treatment of Carcinoid Syndrome

Purpose

In the placebo-controlled Phase III TELESTAR (Telotristat Etiprate for Somatostatin Analogue Not Adequately Controlled Carcinoid Syndrome) trial, the oral tryptophan hydroxylase inhibitor telotristat ethyl significantly reduced bowel movement (BM) frequency during a 12-week, double-blind treatment period in 135 patients with metastatic neuroendocrine tumors with carcinoid syndrome and ≥4 BMs per day. Patients (mean [SD] age, 63.5 [8.9] years; mean [SD] body mass index, 24.9 [4.9] kg/m²) received placebo, telotristat ethyl 250 mg, or telotristat ethyl 500 mg 3 times per day (TID) in addition to somatostatin analogue therapy. Weight loss is associated with uncontrolled carcinoid syndrome and may be associated with reduced survival.

Terlipressin versus norepinephrine as infusion in patients with septic shock: a multicentre,randomised, double-blinded trial

Purpose

Recent clinical data suggest that terlipressin, a vasopressin analogue, may be more beneficial in septic shock patients than catecholamines. However, terlipressin’s effect on mortality is unknown. We set out to ascertain the efficacy and safety of continuous terlipressin infusion compared with norepinephrine (NE) in patients with septic shock.

Methods

In this multicentre, randomised, double-blinded trial, patients with septic shock recruited from 21 intensive care units in 11 provinces of China were randomised (1:1) to receive either terlipressin (20–160 µg/h with maximum infusion rate of 4 mg/day) or NE (4–30 µg/min) before open-label vasopressors. The primary endpoint was mortality 28 days after the start of infusion. Primary efficacy endpoint analysis and safety analysis were performed on the data from a modified intention-to-treat population.

Results

Between 1 January 2013 and 28 February 2016, 617 patients were randomised (312 to the terlipressin group, 305 to the NE group). The modified intention-to-treat population comprised 526 (85.3%) patients (260 in the terlipressin group and 266 in the NE group). There was no significant difference in 28-day mortality rate between the terlipressin group (40%) and the NE group (38%) (odds ratio 0.93 [95% CI 0.55–1.56]; p?=?0.80). Change in SOFA score on day 7 was similar between the two groups: ??7 (IQR ??11 to 3) in the terlipressin group and ??6 (IQR ??10 to 5) in the NE group. There was no difference between the groups in the number of days alive and free of vasopressors. Overall, serious adverse events were more common in the terlipressin group than in the NE group (30% vs 12%; p?<?0.001).

Conclusions

In this multicentre, randomised, double-blinded trial, we observed no difference in mortality between terlipressin and NE infusion in patients with septic shock. Patients in the terlipressin group had a higher number of serious adverse events.

Trial registration

This trial is registered at ClinicalTrials.gov: ID NCT01697410.

     

Floating right heart thrombi: A pooled analysis of cases reported over the past 10 years

Introduction

Floating right heart thrombi (FRHTS) are a rare phenomenon associated with high mortality. Immediate treatment is mandatory, but optimal therapy is controversial.
