Background Prosthesis-patient mismatch (PPM) has been shown to be related to worse survival and hemodynamic outcomes following valve replacement. Women with aortic stenosis (AS) have a smaller annulus than their male counterpart, making them more susceptible to PPM. The objective of this study was to compare the incidence of PPM in a female population with small aortic annulus (SAA) undergoing transcatheter aortic valve replacement (TAVR) versus surgical aortic valve replacement (SAVR) using the Carpentier Edwards Magna Ease bioprosthetic valves (19-21 mm) and the Edwards Sapien 3 and Sapien 3 Ultra transcatheter valves (20-23 mm). Methods This retrospective study was conducted using harmonized databases from two high-volume cardiac surgery centers. Female patients with SAA (≤23 mm) measured by echocardiography who underwent SAVR or TAVR between 2011 and 2022 were included. Patients with pure aortic regurgitation were excluded. The primary endpoint was to compare the incidence of moderate to severe PPM, both measured and predicted, in women receiving TAVR versus SAVR. Secondary endpoints included various clinical outcomes. Results A total of 426 women were included. 64.8% underwent SAVR (mean age: 75) and 35.2% underwent TAVR (mean age: 81). SAVR patients received 19- or 21-mm prostheses (32% and 68%, respectively). Almost all TAVR patients (94%) were assigned a 23 mm prosthesis, with the others receiving a 20 mm prosthesis. While 53% of SAVR patients were predicted to have a moderate to severe PPM (P-PPM), 39% of TAVR patients were predicted to do so ( P = .005). When it came to measured PPM (M-PPM), 73% of SAVR versus 32% of TAVR patients had moderate to severe PPM ( P < .001). Proportions were lower when adjusting for BMI > 30 (P-PPM - SAVR: 25%; TAVR: 19%; P = .148; M-PPM – SAVR: 64%; TAVR: 23%; P < .001). Conclusion In women with SAA, a larger proportion of SAVR patients had moderate to severe P-PPM or M-PPM compared to TAVR patients. Adjusting for BMI > 30 showed similar trends, although overall proportions were lower.

Published: December 2024

Background There are few prospective and large registries on outcomes after aortic valve repair/sparing or replacement in patients with aortic valve regurgitation (AR), with or without ascending aorta aneurysm. Methods A total of 2,026 patients enrolled prospectively in The Aortic Valve Insufficiency and ascending aorta Aneurysm InternATiOnal Registry (AVIATOR) were included in this analysis. The primary endpoint was the composite of all-cause death or aortic valve and/or aorta reintervention. Results 1,630 (80%) received surgical repair/sparing versus replacement in 396 (20%). During a mean follow-up of 3.8 ± 1.9 years, 187 (9.2%) events occurred, including 106 reinterventions and 81 deaths. The incidence of the composite endpoint was higher in the replacement versus repair group (25.3% vs. 11.8%; log-rank p < 0.001). In particular, the incidence of death was higher in the replacement versus repair group (21.9% vs. 4.5%; p < 0.001), while the incidence of reintervention was comparable between groups (8.2% vs. 5.1%; p = 0.16). AR ≥ grade 2 (mild-to-moderate) at discharge (2.9%) was more common in repair versus replacement (3.5% vs. 0.3%; p < 0.0001). AR (Grade 2) at discharge was significantly associated with higher incidence of the primary endpoint (adjusted HR: 2.60 [95% CI 1.01–6.74]; p = 0.04). Conclusion Surgical repair was associated with better survival than replacement at mid-term follow-up without increased risk of reoperation. However, the incidence of postoperative AR ≥ grade 2 was higher in repair than in replacement surgery. AR ≥ grade 2 at discharge was a strong predictor for reintervention during follow-up, stressing the importance of achieving complete correction of AR at the time of aortic valve repair.

Abstract
Palygorskite (Pal) shows great potential for physical, chemical and biological uses due to its colloidal, catalytic and adsorption properties. Pal mines, however, are facing the challenge of low-grade materials (5–15%), making it difficult to use Pal in emerging fields such as new materials, environmental protection and health. Therefore, there is an urgent need to develop an efficient method for separating and purifying Pal to obtain high purity levels. Hence, we have developed a dispersant-assisted rotating liquid film reactor separation strategy based on sodium hexametaphosphate as the dispersant. This strategy utilizes the double electron layer of Pal and the density difference between impurities to achieve effective disaggregation and purification of Pal bundles through the promotion of repulsive driving effects. Under optimal conditions, the purity of Pal can be increased from less than 10% to over 80%. This research presents a novel approach to the efficient refining of low-grade Pal. The crudely purified Pal’s adsorption capacity for methylene blue increased from 84.2 to 256.4 mg g–1.
Contrasting assemblages of secondary minerals after beryl from the granitic pegmatites Drahonín IV and Věžná I; evidence for high variability of mineralised fluids in the Rožná-Olší ore field area, Czech Republic

Published: December 2024

Abstract
This work presents data for the mineral assemblages, composition and Raman spectroscopy of proximal secondary Be and associated minerals in pseudomorphs after beryl from granitic pegmatites located along the contacts of major regional geological units. The pegmatites differ in their position relative to the ductile to brittle shear zones within the Rožná-Olší ore field (U-deposit), Czech Republic. Extensive dissolution of beryl crystals in the beryl–columbite pegmatites Drahonín IV and Věžná I situated within or close to the shear zones is evident in contrast to minor alteration of beryl in the Dolní Rožínka and Kovářová pegmatites located outside of the shear zones. Near-total replacement of beryl crystals, up to 40 cm in length, from the Drahonín IV pegmatite, located in the Olší shear zone formed the following secondary Be minerals in order of their abundance: bavenite–bohseite > bertrandite ≫ milarite > hydroxylgugiaite. This assemblage is also characterised by the presence of sulfides (pyrite, galena, sphalerite) and zeolites. Such an extensive replacement process required a substantial fluid flow and is very possibly related to the pre-uranium quartz–sulfide and carbonate–sulfide mineralisation events within the Rožná-Olší ore field. Alteration products resulting from breakdown of beryl in the Věžná I pegmatite follow the sequential substages (bertrandite + K-feldspar ± harmotome → epididymite + K-feldspar → hydroxylgugiaite + K-feldspar) and locally show cross-cutting textures. These assemblages were generated by post-magmatic residual fluids (early assemblage bertrandite + K-feldspar) as well as fluids related to a retrograde stage of metamorphism, compositionally contrasting with the host serpentinite, and perhaps also hydrothermal processes associated with the Olší shear zone. The pegmatites Dolní Rožínka and Kovářová, located outside of the shear zones, exhibit only a low degree of alteration and have differing textural and paragenetic development. Highly variable assemblages of secondary minerals after beryl are excellent mineral indicators of hydrothermal overprinting in granitic pegmatites during a variety of subsolidus processes.

Published: December 2024

Abstract
Background
Extracellular vesicles (EVs) are essential for cell-to-cell communication because they transport functionally active molecules, including proteins, RNA, and lipids, from secretory cells to nearby or distant target cells. Seminal plasma contains a large number of EVs (sEVs) that are phenotypically heterogeneous. The aim of the present study was to identify the RNA species contained in two subsets of porcine sEVs of different sizes, namely small sEVs (S-sEVs) and large sEVs (L-sEVs). The two subsets of sEVs were isolated from 54 seminal plasma samples by a method combining serial centrifugations, size exclusion chromatography, and ultrafiltration. The sEVs were characterized using an orthogonal approach. Analysis of RNA content and quantification were performed using RNA-seq analysis.

Results
The two subsets of sEVs had different size distributions (P < 0.001). They also showed differences in concentration, morphology, and specific protein markers (P < 0.05). A total of 735 RNAs were identified and quantified, which included: (1) mRNAs, rRNAs, snoRNAs, snRNAs, tRNAs, other ncRNAs (termed as “all RNAs”), (2) miRNAs and (3) piRNAs. The distribution pattern of these RNA classes differed between S-sEVs and L-sEVs (P < 0.05). More than half of “all RNAs”, miRNAs and piRNAs were found to be differentially abundant between S- and L-sEVs (FDR < 0.1%). Among the differentially abundant RNAs, “all RNAs” were more abundant in L- than in S-sEVs, whereas the most of the miRNAs were more abundant in S- than in L-sEVs. Differentially abundant piRNAs were equally distributed between S- and L-sEVs. Some of the all RNAs and miRNAs found to be differentially abundant between S- and L-sEVs were associated with sperm quality and functionality and male fertility success.

Conclusions
Small and large sEVs isolated from porcine seminal plasma show quantitative differences in RNA content. These differences would suggest that each sEV subtype exerts different functional activities in the targeted cells, namely spermatozoa and functional cells of the female reproductive tract.

Published: December 2024

Abstract
Background
The aim of this study is to develop a method we call “cost mining” to unravel cost variation and identify cost drivers by modelling integrated patient pathways from primary care to the palliative care setting. This approach fills an urgent need to quantify financial strains on healthcare systems, particularly for colorectal cancer, which is the most expensive cancer in Australia, and the second most expensive cancer globally.

Methods
We developed and published a customized algorithm that dynamically estimates and visualizes the mean, minimum, and total costs of care at the patient level, by aggregating activity-based healthcare system costs (e.g. DRGs) across integrated pathways. This extends traditional process mining approaches by making the resulting process maps actionable and informative and by displaying cost estimates. We demonstrate the method by constructing a unique dataset of colorectal cancer pathways in Victoria, Australia, using records of primary care, diagnosis, hospital admission and chemotherapy, medication, health system costs, and life events to create integrated colorectal cancer patient pathways from 2012 to 2020.

Results
Cost mining with the algorithm enabled exploration of costly integrated pathways, i.e. drilling down in high-cost pathways to discover cost drivers, for 4246 cases covering approx. 4 million care activities. Per-patient CRC pathway costs ranged from $10,379 AUD to $41,643 AUD, and varied significantly per cancer stage such that e.g. chemotherapy costs in one cancer stage are different to the same chemotherapy regimen in a different stage. Admitted episodes were most costly, representing 93.34% or $56.6 M AUD of the total healthcare system costs covered in the sample.

Conclusions
Cost mining can supplement other health economic methods by providing contextual, sequence and timing-related information depicting how patients flow through complex care pathways. This approach can also facilitate health economic studies informing decision-makers on where to target care improvement or to evaluate the consequences of new treatments or care delivery interventions. Through this study we provide an approach for hospitals and policymakers to leverage their health data infrastructure and to enable real time patient level cost mining.

Published: December 2024

Abstract
Introduction
The ability to detect pathogenic bacteria before the onsets of severe respiratory symptoms and to differentiate bacterial infection allows to improve patient-tailored treatment leading to a significant reduction in illness severity, comorbidity as well as antibiotic resistance. As such, this study refines the application of the non-invasive Secondary Electrospray Ionization-High Resolution Mass Spectrometry (SESI-HRMS) methodology for real-time and early detection of human respiratory bacterial pathogens in the respiratory tract of a mouse infection model.

Methods
A real-time analysis of changes in volatile metabolites excreted by mice undergoing a lung infection by Staphylococcus aureus or Streptococcus pneumoniae were evaluated using a SESI-HRMS instrument. The infection status was confirmed using classical CFU enumeration and tissue histology. The detected VOCs were analyzed using a pre- and post-processing algorithm along with ANOVA and RASCA statistical evaluation methods.

Results
Characteristic changes in the VOCs emitted from the mice were detected as early as 4–6 h post-inoculation. Additionally, by using each mouse as its own baseline, we mimicked the inherent variation within biological organism and reported significant variations in 25 volatile organic compounds (VOCs) during the course of a lung bacterial infection.

Conclusion
the non-invasive SESI-HRMS enables real-time detection of infection specific VOCs. However, further refinement of this technology is necessary to improve clinical patient management, treatment, and facilitate decisions regarding antibiotic use due to early infection detection.

Abstract
Background
Lipid metabolism is influenced by mutations in the EH domain binding protein 1 gene (EHBP1). This study investigated the link between the EHBP1 single-nucleotide polymorphisms (SNPs) and dyslipidemia risks in maintenance dialysis patients with end-stage renal disease in Chinese Han population.

Methods
A total of 539 patients were divided into dyslipidemia (379) and control (160) groups. The patients with dyslipidemia were divided into four subgroups: high low-density lipoprotein cholesterol, low high-density lipoprotein cholesterol (HDLC), high triglyceride (TG) and high total cholesterol groups. The genotype distributions of three EHBP1 SNPs (rs2710642, rs10496099 and rs1168816) were determined by high-throughput sequencing technology and were analyzed via generalized multifactor dimension reduction and binary logistic regression analysis.

Results
The high-TG and control groups differed in terms of the genotype frequency of the rs2710642. One haplotype was detected in both the dyslipidemia and high-TG groups. The risk of dyslipidemia was 2.72-fold higher in participants with rs2710642GG compared with those of rs2710642AA and 2.62-fold higher compared with those with rs2710642AA + GA. Subjects who carried rs2710642GG had a 2.94 times greater risk of high TG levels than those who carried rs2710642AA and a 2.89 times greater risk than those who carried rs2710642AA + GA. Compared with those who carried rs2710642AA + GA, those who carried rs2710642GG were 2.53 times more likely to have low HDLC levels. The rs2710642–body mass index (BMI) (≥ 24 kg/m2) and rs11688816A–rs2710642G haplotype interactions increased the risk of dyslipidemia, and the rs2710642–BMI (≥ 24 kg/m2) interaction increased the risk of high TG levels. The rs10496099–rs2710642 and rs10496099–rs2710642–rs11688816 interactions increased the risk of low HDLC levels.

Conclusions
These results suggest that the EHBP1 rs2710642G and rs2710642GG and interactions with rs11688816A or BMI (≥ 24 kg/m2) were linked to higher dyslipidemia risks in end-stage renal disease patients in Chinese Han population.

Abstract
Background
HIV prevention trials usually require that women of childbearing potential use an effective method of contraception. This is because the effect of most investigational products on unborn babies is unknown. We assessed contraceptive use, prevalence and incidence of pregnancy and associated factors among women in a HIV vaccine preparedness study in Masaka, Uganda.

Methods
HIV sero-negative women (18–45 years) at high risk of HIV infection identified through HIV counselling and testing (HCT) were recruited between July 2018 and October 2022. Study procedures included collection of baseline socio-demographics and contraceptive use data, quarterly HCT, counselling on and provision of contraceptive methods onsite/through referral, and 6-monthly urine pregnancy tests. Multivariable Logistic and Poisson regression analyses were conducted to determine factors associated with contraceptive use, prevalence, and incidence of pregnancy.

Results
652 (73%) of 891 women reported contraceptive use at baseline. Contraceptive use was higher in women who were in a relationship/married/cohabiting [adjusted odds ratio (aOR) = 1.60; 95% confidence interval (CI) 1.07–2.40] or divorced/separated/widowed [aOR = 1.86; 95% CI 1.24–2.79] versus those that were single, and among women reporting transactional sex [aOR = 2.10; 95% CI 1.16–3.80] versus those who did not. Baseline pregnancy prevalence was 4% (95% CI 3–6%) and lower in women who reported using long-acting contraceptive methods (aOR = 0.17; 95% CI 0.07–0.39) versus women who did not use these methods. A total of 65 pregnancies over 301.3 person-years of observation (PYO), an incidence rate of 21.6/100 (95% CI 16.9–27.5) PYO, higher among younger women (≤ 24 versus 25 + years, adjusted incidence rate ratio = 1.97; 95% CI 1.15–3.40).

Conclusion
We observed a high pregnancy incidence in this cohort. Innovative strategies that promote sustained and consistent use of highly effective contraceptive methods especially for young women will be critical to the success of HIV prevention trials in this and similar populations.

Published: December 2024

Abstract
Background
The aim of our multicenter study was to investigate the implementation of the European Fabry guidelines on therapeutic recommendations in female patients with Fabry disease (FD) and to analyze the impact of enzyme replacement therapy (ERT) in treated and untreated females.

Results
Data from 3 consecutive visits of 159 female FD patients from 6 Fabry centers were retrospectively analyzed. According to their treatment, patients were separated in 3 groups (untreated, n = 71; newly ERT-treated, n = 47; long-term ERT-treated, n = 41). Clinical presentation and laboratory data, including plasma globotriaosylsphingosine (lyso-Gb3) levels were assessed. The observation time ranged from 49 to 62 months. ∼90% of female patients treated with ERT presented with at least one organ manifestation justifying treatment according to current European guidelines. Untreated females showed a less severe disease load with less FD-typical organ damage. All groups presented with a stable cardiac status (all p > 0.05) over time. ERT-treated females presented with a slight yearly loss of estimated glomerular filtration (eGFR) over time (both p < 0.05), which was comparable to the natural decline for this age. Plasma lyso-Gb3 levels were higher in ERT-treated females and decreased by 0.95 [-4.44 to 4.08] ng/ml/year (p = 0.0002) in those who were newly ERT-treated.

Conclusions
Severely affected females with FD who were treated with ERT, and less severely affected untreated females, showed a broadly stable disease course over 5 years. The treatment decisions were largely based on the European guidelines for FD. In untreated females, it is crucial to explore if organ involvement is FD-related in order to make the correct treatment decision.
