Using complaints from obstetric care for improving women's birth experiences - a cross sectional study.

INTRODUCTION: Staff shortages and quality in obstetric care is a concern in most healthcare systems and a hot topic in the public debate that has centred on complaints about deficient care. However there has been a lack of empirical data to back the debate. The aim of this study was to analyse and describe complaints in obstetric care. Further, to compare the obstetric complaint pattern to complaints from women about other hospital services. MATERIALS AND METHODS: We used the Healthcare Complaints Analysis Tool to code, analyse and extract contents of obstetric complaint cases in a region of Denmark between 2016 and 2021. We compared the obstetric complaint pattern to all other hospital complaint cases in the same period regarding female patients at a large University Hospital in a cross-sectional study. RESULTS: Complaints regarding obstetric care differed from women's complaints regarding other healthcare services. Women from obstetric care raised more problems per complaint, and tended to complain more about relational issues indicated by odds for complaints about staff shortage four times higher in the obstetric care group. Women from obstetric care had a lower proportion of compensation claims. CONCLUSION: Systematic complaint analysis acknowledged women's experience in obstetric care and may point to areas that potentially need further attention. Complaints from obstetric care show that women experience deficiencies related to relational problems like recognition and individualized support compared to complaints from women receiving other hospital healthcare services.

Urine exosomes from healthy and hypertensive pregnancies display elevated level of α-subunit and cleaved α- and γ-subunits of the epithelial sodium channel-ENaC.

Preeclampsia is characterized by hypertension, proteinuria, suppression of plasma renin-angiotensin-aldosterone, and impaired urine sodium excretion. Aberrantly filtered plasmin in urine may activate proteolytically the γ-subunit of the epithelial sodium channel (ENaC) and promote Na+ reabsorption and urine K+ loss. Plasma and urine was sampled from patients with preeclampsia, healthy pregnant controls and non-pregnant women, and from patients with nephrostomy catheters. Aldosterone concentration, urine plasminogen, and protein were determined. Exosomes were isolated by ultracentrifugation. Immunoblotting was used to detect exosome markers; γ-ENaC (two different epitopes within the inhibitory peptide tract), α-ENaC, and renal outer medullary K-channel (ROMK) and compared with human kidney cortex homogenate. Urine total plasmin(ogen) was significantly increased in preeclampsia, plasma and urine aldosterone was higher in pregnancy compared to non-pregnancy, and the urine Na/K ratio was lower in preeclampsia compared to healthy pregnancy. Exosome markers ALIX and AQP-2 were stably associated with exosomes across groups. Exosomal α-ENaC-subunit migrated at 75 kDa and dominantly at 50 kDa and was significantly elevated in pregnancy. In human kidney cortex tissue and two of four pelvis catheter urine, ~90-100 kDa full-length γ-ENaC was detected while no full-length γ-ENaC but 75, 60, and 37 kDa variants dominated in voided urine exosomes. There was no difference in γ-ENaC protein abundances between healthy pregnancy and preeclampsia. ROMK was detected inconsistently in urine exosomes. Pregnancy and preeclampsia were associated with increased abundance of furin-cleaved α-ENaC subunit while γ-subunit appeared predominantly in cleaved form independently of conditions and with a significant contribution from post-renal cleavage.

Prostasin and matriptase (ST14) in placenta from preeclamptic and healthy pregnant women.

OBJECTIVE: Preeclampsia is characterized by disturbed placentation, hypertension, proteinuria, and suppression of plasma renin, angiotensin II, and aldosterone. Regulated activity of tissue serine proteases, prostasin, and matriptase is necessary for normal placental development in mice. Prostasin activates the renal epithelial sodium channel. We hypothesized that preeclampsia is associated with low prostasin expression in placenta and spillover of prostasin into urine across the defect glomerular barrier. METHODS: In a cross-sectional study, 20 healthy pregnant women and 20 patients suspected of preeclampsia were included. Plasma and urine was obtained before delivery, and placental biopsies were taken immediately after delivery (mean gestational age: control 39 and preeclampsia 38 weeks). RESULTS: Patients with preeclampsia displayed lower levels of aldosterone in plasma and in spot urine normalized for creatinine (P = 0.0001). Prostasin, matriptase, hepatocyte growth factor activator inhibitor type 1 (HAI-1) and 2, and nexin-1 mRNA abundances were not different in placental tissue between groups. Prostasin mRNA in placenta correlated directly with nexin-1 and HAI-1 mRNA, but not with matriptase mRNA. Plasma prostasin and placental homogenate prostasin and nexin-1 protein levels did not differ between groups. Activated, arginine 614 (Arg614)-cleaved matriptase was not detectable in placentas. Western blotting showed significant elevated levels of prostasin in urine from preeclamptic patients that correlated with urine albumin. Placenta and plasma prostasin did not correlate to aldosterone or placental weight. CONCLUSION: Preeclampsia is not associated with altered prostasin in placenta or plasma at term, but with increased prostasin in urine. An impact of prostasin-matriptase on placental development is likely to be at the level of activity and not protein abundance.

Diagnosis of preeclampsia with soluble Fms-like tyrosine kinase 1/placental growth factor ratio: an inter-assay comparison.

The angiogenic factor ratio soluble Fms-kinase 1 (sFlt-1)/placental growth factor (PlGF) is a novel diagnostic tool for preeclampsia. We compared the efficacy of the KRYPTOR (BRAHMS) automated assays for sFlt-1 and PlGF with the Elecsys (Roche) assays in a routine clinical setting. Preeclamptic women (n = 39) were included shortly after the time of diagnosis. Normotensive control pregnancies were matched by gestational age (n = 76). The KRYPTOR assays performed comparably or superior to Elecsys (sFlt-1/PlGF area under the curve 0.746 versus 0.735; P = .09; for non-obese 0.820 versus 0.805, P = .047). For early-onset preeclampsia, KRYPTOR area under the curve increased to 0.929 with a 100% specificity for preeclampsia at cut-off 85 and an 88.9% sensitivity for preeclampsia at cut-off 33. For women with preeclampsia and preterm delivery or Hemolysis, Elevated Liver enzymes, Low Platelet count (HELLP) syndrome, the KRYPTOR sFlt-1/PlGF ratio was manifold increased (P < .01). The sFlt-1/PlGF ratio proved especially useful in early-onset preeclampsia, preeclampsia with preterm delivery or HELLP, and among non-obese women.

Urinary plasmin activates collecting duct ENaC current in preeclampsia.

In nephrotic syndrome, plasminogen is aberrantly filtered from plasma to the urinary space and activated along the tubular system. In vitro, plasmin increases ENaC current by proteolytic cleavage of the γ-subunit. It was hypothesized that preeclampsia is associated with plasmin-dependent ability of tubular fluid to activate ENaC. Urine was sampled from 16 preeclamptic (PE) patients and 17 normotensive pregnant women (Ctrl). Urine was analyzed for plasmin(ogen), creatinine, albumin, aldosterone, Na(+), K(+), proteolytic activity, and for its effect on inward current in cortical collecting duct cells (M1 cells) by whole-cell patch clamp. In PE, urine plasmin(ogen): creatinine ratio was elevated 40-fold (geometric mean, 160 versus 4 µg/g; P<0.0001) and urine aldosterone: creatinine ratio was suppressed to 25% of Ctrl (geometric mean, 27 versus 109 µg/g; P<0.001). A significant negative correlation was found in PE between urinary plasmin(ogen) and aldosterone (P<0.05). In PE, proteolytic activity was detected at 90 to 75 kD by gelatin zymography in 14 of 16 patients and confirmed by serine protease assay. Immunoblotting showed active plasmin in PE urine. Whole-cell inward current increased in M1 cells on exposure to urine from PE (173±21%; n=6; P<0.001). The increase in current was abolished by amiloride (2 µmol/L; P<0.001), α(2)-antiplasmin (1 µmol/L; P<0.001), and heat denaturation (P<0.001). Preeclampsia is associated with urinary excretion of plasmin(ogen) and plasmin-dependent activation of ENaC by urine. Proteolytic activation of ENaC by plasmin may contribute to Na(+) retention and hypertension in preeclampsia.

[Relevant trauma in a haemodynamic stable patient should be computed tomographed in spite of pregnancy]. / Relevant traume hos en hæmodynamisk stabil patient bør efterfølges af computertomografi trods graviditet.

A 37 year-old pregnant woman, gestational age 32 weeks, was involved in a motor vehicle accident. Abdominal ultrasound revealed no pathological findings, and the woman was discharged after 24 hours of observation. Three weeks later a healthy girl was delivered by emergency caesarean section due to placental abruption. During surgery a large amount of blood was detected and signs of previous trauma and haematoma to the spleen were revealed. Post-operative abdominal computed tomography scan was performed, revealing a 5 × 7 cm intrasplenic haematoma.

Long-term infant subcutaneous retention of a fragment of fetal scalp electrode following caesarean section.

The authors present the case of an uncommon yet potentially fatal complication after the use of a scalp electrode for intrapartum fetal heart rate monitoring. A 25-year-old nulliparous woman in spontaneous term labour had a fetal scalp electrode applied and subsequently required an emergency cesarean section. After discharge home, the mother noticed a swelling on her baby's head, where the scalp electrode had been attached. Healthcare providers neglected the mother's repeated concerns about the nature of the swelling. Seven months later, a metal spiral was expelled from the baby's head which appeared to be a broken part of the scalp electrode. The remaining metal was removed with no further signs or complications. We are aware of only a few similar cases which have been reported in the published literature.
