Postpartum haemorrhage (PPH) is the leading cause of maternal mortality worldwide. Prophylaxis with oxytocic medication is recommended by the WHO to prevent its occurrence. Carbetocin is a newer oxytocic, with potential to lower PPH rates, reduce the total use of oxytocic drugs and lead to financial savings. Meta-analyses have confirmed a reduction in the use of additional oxytocic medication with the use of carbetocin compared to oxytocin. However, there are few studies evaluating the costs of carbetocin prophylaxis...

The homoleptic compound [PPh₄][CF₃AuCF₃] cleanly undergoes photoinduced oxidative addition of CF₃I to afford the organogold(III) derivative [PPh₄][(CF₃)₃AuI] in good yield and under mild conditions. This compound provides a convenient entry to the chemistry of the perfluorinated (CF₃)₃Au fragment whose properties are analyzed with the aid of DFT methods and compared with those of the homologous non-fluorinated (CH₃)₃Au moiety. It is found that reductive elimination of CX₃-CX₃ in the former (X = F) requires a much higher energy barrier than in the latter (X = H) and is therefore considerably less favored...

The synthesis of inorganic N-P(III)-Ch-based macrocycles [-PhP-NMe-PPh-Ch-]2 (8Ch; Ch = S, Se) is presented by incorporating two nitrogen, two chalcogen, and four phosphorus atoms. The macrocycles are conveniently obtained via the cyclocondensation reaction of Na2Ch (Ch = S, Se) with the acyclic dichlorodiphosphazane ClPhP-NMe-PClPh (9). Treatment with elemental sulfur (S8) or gray selenium (Segray) results in an oxidative ring contraction to give 1,3,2,4-thiazadiphosphetidine 2,4-disulfide (10S) and 1,3,2,4-selenazadiphosphetidine 2,4-diselenide (10Se), respectively...

BACKGROUND: Women who undergo intrapartum caesarean delivery (CD) are at increased risk of postpartum hemorrhage (PPH) compared with those undergoing prelabor CD. To determine whether the presence and strength of the associations between individual risk factors and severe PPH vary among women undergoing prelabor CD or intrapartum CD, stratified analyses are needed according to CD subtype. METHODS: To identify risk factors for severe PPH within 2 distinct CD populations, prelabor CD and intrapartum CD, we performed 2 case-control studies...

Delayed post-pancreatectomy hemorrhage (PPH) is a relatively uncommon, but feared, complication after pancreaticoduodenectomy (PD). A splenic artery pseudoaneurysm is a rare cause of delayed PPH after a PD. This paper describes the case of a patient with PD used to treat a distal bile duct cholangiocarcinoma complicated with a clinically significant pancreatic fistula and secondary intraabdominal abscess. Computed tomography-guided drainage of the abscess was performed with an apparently favourable outcome; the patient was discharged on postoperative day (POD) 35 and the abdominal drains were removed on POD 50...

Throughout the past years we stepwise modified our immunosuppressive treatment regimen for patients with antibody-mediated rejection (ABMR). Here, we describe three consecutive groups treated with different regimens. From 2005 until 2008, we treated all patients with biopsy-proven ABMR with rituximab (500 mg), low-dose (30 g) intravenous immunoglobulins (IVIG), and plasmapheresis (PPH, 6x) (group RLP, n = 12). Between 2009 and June 2010, patients received bortezomib (1.3 mg/m(2), 4x) together with low-dose IVIG and PPH (group BLP, n = 11)...

PURPOSE OF REVIEW: Examine the available results from population-based studies to test the hypothesis that differences between countries in medical practices for the management of labour, delivery and early bleeding may lead to a differential risk of post-partum haemorrhage (PPH)-related maternal morbidity and in the need for PPH-related invasive therapies. RECENT FINDINGS: International comparison of ratios of maternal mortality due to PPH shows significant differences between developed countries...

Although it is widely accepted that uterine artery embolization (UAE) is an effective therapeutic strategy for postpartum hemorrhage (PPH), no consensus has been reached regarding the efficacy of UAE in patients with PPH with disseminated intravascular coagulation (DIC). This single-center retrospective cohort study included patients treated with UAE using NBCA for PPH between 2010 and 2015. The patients were divided into DIC and non-DIC groups, according to the obstetrical DIC score and the overt DIC diagnostic criteria issued by the International Society of Thrombosis and Haemostasis (ISTH), and their clinical outcomes were compared...

OBJECTIVE: Postpartum haemorrhage (PPH) is a significant cause of maternal morbidity and mortality. The most common cause is an inability of the uterus to contract adequately after childbirth. In bimanual compression (BMC), one hand is placed within the vagina and the other hand is on the abdominal wall to compress the uterus. It is effective, but very uncomfortable for the woman. We designed a device that could replicate BMC without inserting a hand vaginally, therefore being less invasive...

: Postprandial hypotension (PPH) is a common condition that occurs primarily in elderly patients with type 2 diabetes mellitus (T2DM). This study aimed to assess the effectiveness of acarbose for PPH; it also investigated possible mechanisms behind PPH development. This single-blind, randomized controlled trial included 91 elderly patients with T2DM, aged between 60 and 80 years, who were inpatients at Beijing Hospital between March 2012 and November 2014. The patients were included into one of three groups: Group A, patients with T2DM without PPH; Group B, patients with T2DM with PPH receiving placebo; and Group C, patients with T2DM with PPH receiving acarbose...

BACKGROUND: Prolonged labour is associated with increased risk of postpartum haemorrhage (PPH), but the role of active pushing time and the relation with management during labour remains poorly understood. METHODS: A population-based cohort study from electronic medical record data in the Stockholm-Gotland Region, Sweden. We included 57 267 primiparous women with singleton, term gestation, livebirths delivered vaginally in cephalic presentation in 2008-14. We performed multivariable Poisson regression to estimate the association between length of second stage, pushing time, and PPH (estimated blood loss >500 mL during delivery), adjusting for maternal, delivery, and fetal characteristics as potential confounders...
