Novel phosphatidylinositol flippases contribute to phosphoinositide homeostasis in the plasma membrane
Authors: Muranaka Yumeka , Shigetomi Ryo , Iwasaki Yugo , Hamamoto Asuka , Nakayama Kazuhisa , Takatsu Hiroyuki , Shin Hye-Won
Published: September 2024

Phosphatidylinositol is a precursor of various phosphoinositides, which play crucial roles in intracellular signaling and membrane dynamics and have impact on diverse aspects of cell physiology. Phosphoinositide synthesis and turnover occur in the cytoplasmic leaflet of the organellar and plasma membranes. P4-ATPases (lipid flippases) are responsible for translocating membrane lipids from the exoplasmic (luminal) to the cytoplasmic leaflet, thereby regulating membrane asymmetry. However, the mechanism underlying phosphatidylinositol translocation across cellular membranes remains elusive. Here, we discovered that the phosphatidylcholine flippases ATP8B1, ATP8B2, and ATP10A can also translocate phosphatidylinositol at the plasma membrane. To explore the function of these phosphatidylinositol flippases, we used cells depleted of CDC50A, a protein necessary for P4-ATPase function and ATP8B1 and ATP8B2, which express in HeLa cells. Upon activation of the Gq-coupled receptor, depletion of phosphatidylinositol 4,5-bisphosphate [PtdIns(4,5)P2] was accelerated in CDC50A knockout (KO) and ATP8B1/8B2 double KO cells compared with control cells, suggesting a decrease in PtdIns(4,5)P2 levels within the plasma membrane of the KO cells upon stimulation. These findings highlight the important role of P4-ATPases in maintaining phosphoinositide homeostasis and suggest a mechanism for asymmetry of phosphatidylinositol in the cytoplasmic leaflet of the plasma membrane.
Acoustic Analysis of Spatiotemporal Variability in Children With Childhood Apraxia of Speech
Authors: Vuolo Janet , Wisler Alan
Published: September 2024

Purpose:

The purpose of this study was to investigate acoustic spatiotemporal variability in children with childhood apraxia of speech (CAS) compared to children with typical development (TD). Increased spatiotemporal variability in children with CAS relative to nonapraxic peers has been documented in multiple kinematic studies. To date, few studies have investigated spatiotemporal variability in CAS using an acoustic signal.

Method:

Data were drawn from 10 children with CAS and 10 children with TD, ranging in age from 5;0 to 11;2 (years;months), who participated in an online study. All children with CAS had a verified diagnosis and showed at least five CAS features across at least two tasks, independently confirmed by two speech-language pathologists with expertise in CAS. Children repeated the sentences “Buy Bobby a puppy” (BBAP) and “Mom pets the puppy” (MPP) 10 times each. The acoustic spatiotemporal index (STI), calculated from the amplitude envelope, was used to investigate acoustic spatiotemporal variability. Using a regression analysis, we analyzed group differences in STI values while controlling for age and gender.

Results:

Children with CAS did not produce enough usable tokens of BBAP to analyze. MPP revealed significantly higher acoustic STI values in children with CAS compared to children with TD. No significant effects were observed for age or gender. Acoustic data collected online without the use of specialized equipment yielded high-quality audio data from which amplitude envelope tracing could be reliably accomplished.

Conclusions:

This study adds to a growing body of empirical data indicating that children with CAS produce speech with more variable spatiotemporal control compared to children with TD. In addition to producing more variable speech, children with CAS were less consistently able to form productions free of phonetic errors. These findings also demonstrate the feasibility of using remote data collection to investigate acoustic spatiotemporal variability, which allows for the recruitment of larger samples of low-incidence populations.

Authors: Power Samantha J. , Piccorelli Annalisa V. , Jones David L. , Neuberger Ilana , Allen Gregory C. , Barhaghi Krystle , Kotlarek Katelyn J.
Published: September 2024

Purpose:

The purpose of the present study is to (a) provide quantitative data on the growth of levator veli palatini (LVP), velopharyngeal (VP), and craniofacial dimensions in children under 12 months while controlling for corrected age and sex and (b) compare variability within age and sex groups.

Method:

Magnetic resonance imaging scans of 75 infants between 0 and 12 months were measured and divided into four age groups. These data were obtained as part of a larger retrospective study. Following exclusion criteria, scans were analyzed, and dependent variables were obtained.

Results:

There was a statistically significant (
p
< .0001) difference between corrected age groups on LVP muscle, VP, and craniofacial variables while controlling for sex. Significant growth effects were observed for LVP length (
p
< .0001), extravelar length (
p
< .0001), intravelar length (
p
= .048), midline thickness (
p
= .0001), origin–origin distance (
p
< .0001), velar length (
p
< .0001), velar thickness (
p
= .003), nasion–sella turcica distance (
p
< .0001), sella turcica–basion distance (
p
< .0001), and hard palate length (
p
< .0001). Significant sex effects were observed for pharyngeal depth (
p
= .026) and effective VP ratio (
p
= .014). When age was treated as a continuous variable, similar results were observed for all variables except pharyngeal depth. Within-group comparisons revealed the most variability occurs between 3 and 5.99 months for LVP and craniofacial variables and between 9 and 11.99 months of age for VP variables. Male participants demonstrated greater variability than female participants.

Conclusions:

Differences were observed in LVP, VP, and craniofacial variables in children under 12 months while controlling for sex. Males demonstrated larger values and greater variability for most variables.
Adductor Laryngeal Dystonia Versus Muscle Tension Dysphonia: Examining the Utility of Automated Acoustic Analysis to Detect Task Dependency as a Distinguishing Feature
Authors: Roy Nelson , Awan Shaheen N. , Jennings Skyler , Jensen Jenna , Merrill Ray M.
Published: September 2024

Objective:

Differentiating adductor laryngeal dystonia (ADLD) and primary muscle tension dysphonia (pMTD) can be challenging. Unlike pMTD, ADLD is described as “task-dependent” with voiced phonemes purportedly provoking greater sign expression than voiceless phonemes. We evaluated the ability of two automated acoustic measures, the Cepstral Spectral Index of Dysphonia (CSID) and creak, to detect task dependency and to discriminate ADLD and pMTD.

Method:

CSID, % creak, and listener ratings of dysphonia severity were obtained from audio recordings of patients with ADLD (
n
= 29) or pMTD (
n
= 33) reading two sentences loaded with either voiced or voiceless phonemes.

Results:

Group × Sentence Type interaction effects confirmed that both “normalized” CSID and % creak detected task-dependent sign expression in ADLD (i.e., worse symptoms on the voiced- vs. voiceless-loaded sentence). However, a stepwise binary logistic regression analysis with group (ADLD vs. pMTD) as the dependent variable and % creak and normalized CSID variables (voiced, voiceless, and voiced vs. voiceless difference) as covariates revealed that the normalized CSID voiceless-laden sentence
z
score was the only significant predictor of group membership. Estimates of diagnostic precision from the normalized CSID voiceless sentence
z
scores were superior to % creak or listener ratings. Finally, the CSID possessed the strongest correlations with listener severity ratings regardless of group or sentence type.

Conclusions:

Although both normalized CSID and % creak detected task-dependent performance as a distinguishing feature of ADLD, a CSID profile wherein (a) the voiceless sentence
z
score was less severe than the voiced sentence and (b) the normalized voiceless sentence
z
score was within approximately 2
SD
s (or less) of typical expectations provided the best estimates of diagnostic precision. Automated acoustic measures such as the CSID and creak provide useful information to objectively discriminate ADLD and pMTD.
Getting Serious About Games: Exploring How Game-Based Learning Is Used in Education and Therapy
Authors: Springle Alisha P.
Published: September 2024

Purpose:

The increasing interest in game-based learning (GBL) provides an opportunity to enhance interprofessional collaboration between speech-language pathologists (SLPs) and teachers. The purpose of this two-part article is to determine the similarities and differences between how teachers and SLPs think about and employ GBL.

Method:

Two distinct methods were used to research GBL. First, a systematic literature review gathered information on teachers' perspectives on GBL, including the benefits and implementation challenges. The important features of the learning games were also catalogued. Then, a qualitative study of focus groups containing both SLPs and teachers examined the shared and disparate views of GBL.

Results:

The initial literature review identified potential shared viewpoints of GBL as a motivational activity with a focus on learning and potential differences in implementation, use of professional time, and balancing fun and learning. The findings of the qualitative study validated that although teachers and SLPs share specific thoughts on GBL, their different patterns of use drive different paths for game selection and development.

Conclusions:

The similarities and differences between how teachers think about and use GBL are reviewed, and clinical implications are discussed. As with many interprofessional issues, GBL can be supported by collaborative practices that allow professionals to share their time and experiences while acknowledging and valuing their different expertise.
Probabilistic coupled EV‐PV hosting capacity analysis in LV networks with spatio‐temporal modelling and copula theory
Authors: Wanninayaka Mudiyanselage Chathuranga D. W. , Hasan Kazi N. , Vahidnia Arash , Rahman Mir Toufikur
Published: September 2024

The authors present an innovative approach for probabilistic coupled electric vehicle (EV) and solar photovoltaics (PV) hosting capacity analysis in low‐voltage (LV) distribution networks. The challenges posed by system uncertainties and correlations between different parameters, such as PV generation and EV charging demand, are addressed using probabilistic modelling. To appropriately incorporate the geographical distribution and time‐variant patterns of EV charging demand, a comprehensive spatio‐temporal (ST) model is developed to capture the trip distance, EV arrival, and charging time. The correlation between the PV generation and EV charging demand is effectively captured by copula theory. The proposed models have been validated using actual EV charging and PV generation data from 36 Australian EV users over 1 year. Power flow simulation with actual data and modelled data have identified EV‐only and coupled EV‐PV hosting capacities in an Australian LV test network. The coupled EV‐PV model presents a higher level of accuracy, having an average mean absolute percentage error (MAPE) of 5.97% compared to independent EV profiles having a MAPE of 10.12%. A voltage profile analysis with the EV and PV profiles also validates the same trend, having MAPE of 1.5% and 1.95%, respectively, for coupled EV‐PV and independent EV profiles.
Machine learning based fault detection technique for hybrid multi level inverter topology
Authors: Chappa Anilkumar , Rao K. Dhananjay , Dhananjaya Mudadla , Dawn Subhojit , Al Mansur Ahmed , Ustun Taha Selim
Published: September 2024

Multilevel inverters (MLIs) have a significant contribution in many industrial sectors due to their improved power quality and lesser voltage stress, over the conventional three‐level inverters. However, the implementation of MLIs with an increased device count creates the scope of development in MLIs topologies. In this regard, a hybrid MLI topology is studied in this paper whose architecture is based on conventional two‐level inverters. This topology has lesser device count characteristics when compared to conventional and most of the recently presented configurations for nine‐level output voltage generation. The major issue of capacitor voltage balancing is resolved by employing an appropriate switching strategy. However, the semiconductor switches are the most vulnerable components and causes the open circuit faults frequently that creates issues in real time operation. Hence, it is important to detect the open circuit fault in switches in the least possible time. A new approach to open circuit fault detection technique based on the analysis of load voltage waveform is proposed in this paper. The wavelet transform technique has been implemented for feature extraction of load voltage. Later, the classification of the fault has been achieved by training an artificial neural network (ANN). The proposed work has been studied in MATLAB/simulation and the obtained results are verified experimentally.
Channel state information based physical layer authentication for Wi‐Fi sensing systems using deep learning in Internet of things networks
Authors: Roopak Monika , Ran Yachao , Chen Xiaotian , Tian Gui Yun , Parkinson Simon
Published: September 2024

Security problems loom big in the fast‐growing world of Internet of Things (IoT) networks, which is characterised by unprecedented interconnectedness and data‐driven innovation, due to the inherent susceptibility of wireless infrastructure. One of the most pressing concerns is user authentication, which was originally intended to prevent unwanted access to critical information but has since expanded to provide tailored service customisation. We suggest a Wi‐Fi sensing‐based physical layer authentication method for IoT networks to solve this problem. Our proposed method makes use of raw channel state information (CSI) data from Wi‐Fi signals to create a hybrid deep‐learning model that combines convolutional neural networks and long short‐term memory networks. Rigorous testing yields an astonishing 99.97% accuracy rate, demonstrating the effectiveness of our CSI‐based verification. This technology not only strengthens wireless network security but also prioritises efficiency and portability. The findings highlight the practicality of our proposed CSI‐based physical layer authentication, which provides lightweight and precise protection for wireless networks in the IoT.
Impact of ice growth on the physical and chemical properties of dense cloud cores
Authors: Sipilä O. , Caselli P. , Juvela M.
Published: September 2024

We investigated the effect of time-dependent ice growth on dust grains on the opacity and hence on the dust temperature in a collapsing molecular cloud core, with the aim of quantifying the effect of the dust temperature variations on ice abundances as well as the evolution of the collapse. To perform the simulations, we employed a one-dimensional collapse model that self-consistently and time-dependently combines hydrodynamics with chemical and radiative transfer simulations. The dust opacity was updated on the fly based on the ice growth as a function of the location in the core. The results of the fully dynamical model were compared against simulations run with different values of fixed ice thickness. We found that the ice thickness increases quickly and reaches a saturation value (as a result of a balance between adsorption and desorption) of approximately 90 monolayers in the central core (volume density ~104 cm−3), and several tens of monolayers at a volume density of ~103 cm−3, after only a few 105 yr of evolution. The results thus exclude the adoption of thin (approximately ten monolayer) ices in molecular cloud simulations except at very short timescales. However, the differences in abundances and the dust temperature between the fully dynamic simulation and those with a fixed dust opacity are small; abundances change between the solutions generally within a factor of two only. The assumptions on the dust opacity do have an effect on the collapse dynamics through the influence of the photoelectric effect on the gas temperature, and the simulations take a different time to reach a common central density. This effect is, however, small as well. In conclusion, carrying out chemical simulations using a dust temperature corresponding to a fixed opacity seems to be a good approximation. Still, although at least in the present case its effect on the overall results is limited – as long as the grains are monodisperse – ice growth should be considered to obtain the most accurate representation of the collapse dynamics. We have found in a previous work that considering a grain size distribution leads to a complicated ice composition that depends on the grain size nonlinearly. With this in mind, we will carry out a follow-up study where the influence of the grain size on the present simulation setup is investigated.
Protéger la nature ou protéger les animaux ?
Les chats harets à la croisée des éthiques environnementales
Authors: Atlan Anne , Rossary Mila , Van Tilbeurgh Véronique
Published: September 2024

La protection de l’environnement et la protection des animaux se rejoignent lorsqu’il s’agit de considérer les animaux endémiques, mais entrent en opposition pour les prédateurs introduits qui constituent une menace pour les espèces locales. L’objectif de protection de la biodiversité, qui implique d’éradiquer ces prédateurs, se heurte à la défense du bien-être animal, particulièrement lorsqu’il s’agit d’animaux sensibles comme les mammifères. Le chat Felis catus cumule un fort potentiel de nuisance pour la biodiversité et un fort attachement affectif de la part de la population. Nous utilisons une approche socioécologique pour analyser différents cas de gestion des chats en France métropolitaine et ultramarine, et une analyse bibliographique de situations rencontrées en Australie et aux États-Unis. Cette analyse comparative permet d’illustrer comment l’articulation entre protection de la nature, protection des animaux et acceptabilité sociale implique de prendre en compte la pluralité des éthiques environnementales.
Improved Crouzeix-Raviart scheme for the Stokes and Navier-Stokes problem
Authors: Chénier Eric , Jamelot Erell , Le Potier Christophe , Peitavy Andrew
Published: September 2024

The resolution of the incompressible Navier-Stokes equations is tricky, and it is well known that one of the major issue is to approach the space:

H1(Ω)∩ H(div 0; Ω) := {v ∈ H1(Ω) : div v = 0}.

The non-conforming Crouzeix-Raviart finite element are convenient since they induce local mass conservation. Moreover they are such that the stability constant of the Fortin operator is equal to 1. This implies that they can easily handle anisotropic mesh. However spurious velocities may appear and damage the approximation.

We propose a scheme here that allows one to reduce the spurious velocities. It is based on a new discretisation for the gradient of pressure based on the symmetric MPFA scheme (finite volume MultiPoint Flux Approximation).
Evaluation of the 1-D hyperbolic quadrature method of moments for non-equilibrium flows
Authors: Laurent Frédérique , Fox Rodney O.
Published: September 2024

When considering moment methods for the resolution of the free-transport term of the 1-D kinetic equation, the hyperbolic quadrature method of moments (HyQMOM) closure introduced in [12] leads to a globally hyperbolic system of conservation equations. Here, the HLL scheme used for its resolution is first proved to be realizable, i.e., allows computed moments to remain moments of a positive measure, exploiting a new property shown for the closure. Then, the accuracy of HyQMOM is evaluated for two test cases from the literature. The first is related to rarefied gas dynamics, where the internal structure of stationary shock waves is simulated for non-equilibrium cases. The second is related to the description of a population of inertial particles, where two populations cross each other without interacting.

Published: September 2024

In Germany, significant incidents must be reported to the competent authority since 12/31/2018 (section 108 Radiation Protection Ordinance (StrlSchV)). After assessment and evaluation of the reports, the competent authority submits the relevant information via a web-based reporting system (BeVoMed) to the Federal Office for Radiation Protection (BfS), which publishes the results derived therefrom. The present paper evaluates significant incidents related to X-ray exposures on humans.

All reports on incidents in X-ray diagnostics and interventional radiology between 01/2019 and 10/2023, which were completed with detailed information until the reporting day (31/10/2023), were included. The following aspects were statistically evaluated: classification as an incident (section 1 subsection (22) StrlSchV), significance (section 108 StrSchV), classification to Annex 14 StrlSchV, assignment to the forms of care in the German healthcare system, and development of the reporting frequency over time. Furthermore, the content of the reports was systematically evaluated with regard to conspicuous clusters and typical problems.

Until the reporting day, 383 reports (355 completed) were received. 252 reports (228 in X-ray diagnostics, 24 in interventional radiology) referred to significant incidents and were included in the detailed evaluation. Reporting frequency increased in X-ray diagnostics, whereas there was no trend in interventional radiology. Most of the significant incidents concerned examinations on an individual person (category I, criterion 2a or category II, criteria 2a and 3a) in the in-patient sector – especially in maximum care hospitals. Frequent errors concerned the inappropriate choice of parameters/protocols or were related to the administration of a contrast agent. Despite the overall positive trend, the establishment of awareness and error culture remains challenging.
Effect of Lower Limb Muscle Fatigue on Dynamic Balance Performance in
Healthy Young Adults: Role of Arm Movement

Published: September 2024

There is evidence that balance performance deteriorates due to exercise-induced
muscle fatigue. However, it is unknown if free arm movement during balance
testing can compensate for, or restricted arm movement can amplify these
performance degradations. Thus, the objective of this study was to compare the
effects of free versus restricted arm movement on balance performance under
non-fatigued and fatigued conditions. Fifty-two healthy participants (men=31,
women=21; age=22.6±1.6 years) were assessed for their dynamic balance (reach
distances for the Y Balance Test – Lower Quarter) under non-fatigued and
fatigued (repetitive vertical bipedal box jumps until failure) conditions using
two different arm positions: free (move the arms freely) and restricted (keep
the arms akimbo) arm movement. Restriction of arm movement (all
p<0.001; 0.48≤η
p
2≤0.79) and application
of fatigue (p≤0.003; 0.16≤η
p
2≤0.28)
independently, but not the interaction between the two (except for the
posteromedial reach direction: p=0.046;
η
p
2=0.08), resulted in significantly
deteriorated lower limb reach distances. These findings suggest that free arm
movement and thus the use of an ‘upper body strategy’ has no compensatory effect
on muscle fatigue-induced balance deteriorations.
Ein äußerst seltener Fall von multiplen Rezidiven eines Urothelzellkarzinoms in einer ilealen Neoblase: Fallbericht und Literaturübersicht

Published: September 2024

In bis zu 18% tritt nach kurativer radikaler Zystektomie wegen eines Urothelkarzinoms ein Rezidiv auf. Zumeist manifestieren sich die Rezidive in den regionären Lymphknoten oder im verbliebenen oberen oder unteren Harntrakt. Extrem selten tritt ein Rezidiv in einer Neoblase auf, zumal es sich um ein anderes embryonales Keimblatt handelt.

Wir berichten über einen Fall, bei dem 10 Jahre nach der Zystoprostatektomie multiple Urothelkarzinomrezidive nur in der Neoblase auftraten. Daraufhin wurde die Neoblase entfernt und ein Sigma-Conduit angelegt. Trotzdem trat 6 Monate später eine generalisierte Metastasierung auf, woran der Patient wenig später verstarb. Zurzeit gibt es aufgrund der Seltenheit dieses Krankheitsbilds keine Behandlungsrichtlinien. Wir schildern unsere Erfahrungen und geben eine Literaturübersicht.
In Vitro Anti-inflammatory Effects of Larch Turpentine, Turpentine Oil, Eucalyptus Oil, and Their Mixture as Contained in a Marketed Ointment
Authors: Appel Kurt , Rose Thorsten , Zimmermann Christian , Günnewich Nils
Published: September 2024

An ointment containing larch turpentine, turpentine oil, and eucalyptus oil has been used for almost a century for the symptomatic treatment of mild, localized, purulent inflammations of the skin. Its clinical efficacy in the treatment of skin infections has been shown in clinical trials, but the mode of action of the active ingredients on inflammation is not known. We studied the anti-inflammatory properties of the active ingredients of the ointment and their mixture in a human monocyte cell model, in which the cells were stimulated with lipopolysaccharide and incubated with the test substances. The cytotoxic threshold of each test substance and the mixture was identified using the alamarBlue assay, and their anti-inflammatory activity was assessed by measuring the release of interleukins IL-1β, IL-6, IL-8, monocyte chemoattractant protein-1, prostaglandin E2, and TNF-α. Cell toxicity was observed at a mixture concentration of 10 µg/mL. All
immunological assays were carried out at nontoxic concentrations. Larch turpentine decreased IL-1β, monocyte chemoattractant protein-1, and prostaglandin E2 release at a concentration of 3.9 µg/mL and TNF-α at concentrations > 1.95 µg/mL, whereas eucalyptus oil and turpentine oil had no relevant inhibitory effects. The mixture dose-dependently inhibited IL-1β, IL-6, monocyte chemoattractant protein-1, prostaglandin E2, and TNF-α release at concentrations > 1 µg/mL. IL-8 release was only marginally affected. The anti-inflammatory activity of the herbal ingredients and their mixture was confirmed in this model. This effect seems to be mediated mainly by larch turpentine, with turpentine oil and eucalyptus oil exerting an additive or possibly synergistic function.

Objective Both hepatitis C virus (HCV) and opioid use disorder (OUD) have been associated with higher rates of preterm birth (PTB). It is unknown whether the higher prevalence of HCV in individuals with OUD may contribute to this association. The objective of this study is to evaluate the association between HCV and PTB in pregnant individuals with OUD.

Study Design We conducted a retrospective cohort of pregnant individuals with OUD who participated in more than three visits in a co-located multidisciplinary program. Inclusion criteria were a diagnosis of OUD, participation in treatment/prenatal care program, and laboratory evaluation of HCV status. The primary exposure was the presence of HCV antibodies, and secondarily, a detectable viral load (viremia). The primary outcome was PTB, which was further classified as spontaneous or iatrogenic. Multivariable logistic regression was used to detect associations while adjusting for race, history of prior PTB, and tobacco use.

Results A total of 941 individuals were included in the study, 404 with HCV and 537 without. Rates of PTB did not differ between those with compared to those without HCV (20.3 vs. 23.8%, adjusted odds ratio [aOR] = 0.75 [95% confidence interval (CI): 0.53–1.07]). There were similar rates of spontaneous PTB (13.1 vs. 16.2%, aOR = 0.79 [95% CI: 0.43–1.45]) and iatrogenic PTB (7.2 vs. 7.6%, aOR = 1.26 [95% CI: 0.69–2.30]). Comparing those with viremia to those without, there were also similar rates of overall PTB (21.6 vs. 17.9%, aOR = 0.86 [95% CI: 0.52–1.44]), spontaneous PTB (13.3 vs. 12.9%, aOR = 0.97 [95% CI: 0.52–1.87]), and iatrogenic PTB (8.3 vs. 5.0%, aOR = 1.83 [95% CI: 0.76–4.94]).

Conclusion HCV does not appear to be associated with spontaneous or iatrogenic PTB in pregnant persons with OUD who are engaged in treatment and prenatal care. The role of co-located multidisciplinary prenatal and addiction programs in the association between HCV and PTB warrants further investigation.

Published: September 2024

Background Increased clot permeability and susceptibility to lysis have been reported in women with heavy menstrual bleeding. We hypothesized that similar alterations in fibrin clot properties may also be present in women with postpartum hemorrhage (PPH) of unknown cause.

Objective To determine fibrin clot properties and their determinants in women after PPH of unknown cause.

Methods We studied 52 consecutive women, aged 35 years (27–40), after at least 3 months since PPH of unknown cause and 52 matched controls for age, weight, and fibrinogen. Coagulation factors (F), antithrombin, thrombin generation, along with a comprehensive plasma fibrin clot analysis including fibrin polymerization, clot permeability (K
s), and fibrinolysis efficiency were determined.

Results Women with PPH showed reduced activity of FII (−10.3%), FV (−6.6%), FIX (−6.5%), FX (−7.2%), and FXI (−5.7%) compared with the controls, though all values were within ranges (all p < 0.05). There were no intergroup differences in fibrinogen, FVIII, FXIII, and thrombin generation. The PPH group formed with a delay looser plasma fibrin network (K
s; +16.3%, p = 0.008) with lower maximum absorbance and shorter clot lysis time (CLT; −13.5%, p = 0.001) compared with the controls. On multivariable logistic regression, PPH was independently associated with higher C-reactive protein (per 1 mg/L, odds ratio [OR] = 1.70, 95% confidence interval [CI]: 1.09–2.68), lower FII (per 1%, OR = 0.93, 95% CI: 0.89–0.98), lower FV (per 1%, OR = 0.93, 95% CI: 0.89–0.97), and shorter CLT (per 1 minute, OR = 0.94, 95% CI: 0.90–0.98).

Conclusion Prohemorrhagic fibrin clot properties, with lower, though normal coagulation factors, characterize women with PPH of unknown cause, which suggests novel mechanisms contributing to this type of bleeding.
