Abstract

The edge-to-edge mitral valve repair technique, invented by Alfieri and colleagues, introduced valve repair as a treatment option for patients with complex diseases where standard annuloplasty and related repair techniques are insufficient, due to annular calcification and patient frailty. We retrospectively evaluated the results of a transaortic edge-to-edge mitral valve repair (Alfieri stitch) in high-risk patients who were undergoing aortic valve replacement. From February, 2012 to December, 2017, 43 patients underwent transaortic edge-to-edge mitral valve repair with concomitant aortic valve replacement at a single institution. Preoperative and postoperative echocardiograms were compared. Home telephone follow up was conducted and postoperative morbidity was examined, including the need for reoperation, stroke and cardiac arrhythmia. 30-day and long-term survival rates were also determined. Mitral regurgitation (MR) was graded semi-quantitatively as 0 (trace and/or none), mild (1), moderate (2) or moderate to severe (3-4). The patients were 74 ± 7.8 years old. 65% of the patients were male. Mean cardiopulmonary bypass time was 115 ± 37 minutes and mean cross-clamp time was 71 ± 23 minutes. There was a significant improvement in preoperative vs postoperative median MR grade (2 (IQR 2-3) vs 0 (IQR 0-1); P = 0.05). Follow-up transthoracic echocardiograms in 29 patients obtained at a median of 9 months' (range 3 - 19 months') and in 16 patients at a median of 34 months' postoperatively (range 21 - 53 months') showed mild (1 (IQR 1-2)) grade of mitral regurgitation. 30-day survival was 98%. Long term survival at 12 and 24 months' were 88% and 81% respectively. Mitral valve reoperation was conducted in 1 patient (2%), who was suffering of endocarditis. Stroke occurred in 2 patients (7%). Cardiac arrhythmia was observed in 15 patients (35%). 8 patients (19%) suffered from atrial fibrillation and 7 patients (16%) displayed atrioventricular blockage. 10 patients (23%) could be treated conservatively and 5 patients (12%) needed implantation of a pacemaker. Transaortic edge-to-edge mitral valve repair can be safely performed during aortic valve replacement in high-risk patients and improves even long-term MR grade. Postoperative cardiac arrhythmia occurs frequently. 66% of them could be treated successfully by conservative procedures.

Abstract

Background The World Health Organization predicts a striking rise in the burden of traumatic brain injury (TBI) burden in the next decades. A disproportionately large increase is predicted in low- and middle-income countries, which have brain injury rates 3 times higher than high-income countries. The aim of this study was to identify current TBI practices and treatment capacity in 3 low- and middle-income countries: Republic of Armenia, Georgia, and Republic of Moldova. Methods After a national inventory of hospitals treating TBI, a situational analysis was conducted in the highest volume adult and pediatric hospital in each country. The situational analysis included key informant interviews with content analysis and a quantitative checklist of treatment resources. Results All 3 countries follow international, national, and hospital protocols for TBI treatment, and the in-hospital management of patients with TBI is similar to international standards in all 3 countries. Although health care specialists were well trained, however, lack of proper equipment, a scant number of hospitals outside the capital region, lack of specialized personnel in regional areas, and lack of rehabilitation services were mentioned as difficulties in interviews from all 3 countries. Conclusions Particular gaps were found in pre-hospital and rehabilitative care, as well as national leadership and data collection. Surveillance and standardized data collection are important measures to fill treatment gaps and reduce the burden of TBI.

Abstract

As a result of increased harmful algal blooms and hypoxia in Lake Erie, the US and Canada revised their phosphorus loading targets under the 2012 Great Lakes Water Quality Agreement. The focus of this paper is the Detroit River and its watershed, a source of 25% of the total phosphorus (TP) load to Lake Erie. Its load declined 37% since 1998, due chiefly to improvements at the regional Great Lakes Water Authority Water Resource Recovery Facility (WRRF) in Detroit and phosphorus sequestered by zebra and quagga mussels in Lake Huron. In addition to the 54% of the load from Lake Huron, nonpoint sources contribute 57% of the TP load and 50% of the dissolved reactive phosphorus load, with the remaining balance from point sources. After Lake Huron, the largest source is the WRRF, which has already reduced its load by over 40%. Currently, loads from Lake Huron and further reductions from the WRRF are not part of the reduction strategy, therefore remaining watershed sources will need to decline by 72% to meet the Water Quality Agreement target - a daunting challenge. Because other urban sources are very small, most of the reduction would have to come from agriculturally-dominated lands. The most effective way to reduce those loads is to apply combinations of practices like cover crops, buffer strips, wetlands, and applying fertilizer below the soil surface on the lands with the highest phosphorus losses. However, our simulations suggest even extensive conservation on those lands may not be enough.

Abstract

International audience; The present protocol describes how to measure experimentally the slow protein dynamics that take place upon the thermal unfolding of the B subunit cholera toxin pentamers using broadband dielectric spectroscopy (BDS) in weakly hydrated and nanoconfined conditions. Transient unfolding intermediates, rarely identified otherwise, are revealed thanks to the B subunit's remarkable heat resistance up to 180°C and distinct molecular dynamics. The frequencies detected experimentally are consistent with the spatiotemporal scales of motions of molecular dynamics simulation.For complete details on the use and execution of this protocol, please refer to Bourgeat et al. (2021, 2019).

Abstract

Auristatins are a class of highly cytotoxic tubulin-disrupting peptides, which have shown limited therapeutic effect as free agents in clinical trials. In our continuing effort to develop acid-sensitive albumin-binding anticancer drugs exploiting circulating serum albumin as the drug carrier, we investigated the highly toxic drug payload auristatin E to assess whether the corresponding albumin-binding prodrugs were a viable option for achieving significant and concomitant tolerable antitumor activity. To achieve our goal, we developed a new aromatic maleimide-bearing linker (Sulf07) which enhanced both water solubility and stability of the prodrugs. In this study, we describe two auristatin E-based albumin-binding drugs, AE-Keto-Sulf07 and AE-Ester-Sulf07, which were designed to release the active compound at the tumor site in a pH-dependent manner. These prodrugs incorporate an acid-sensitive hydrazone bond, formed by the reaction of a carbonyl-containing auristatin E derivative with the hydrazide group of the water-solubilizing maleimide-bearing linker Sulf07. A panel of patient- and cell-derived human tumor xenograft models (melanoma A375, ovarian carcinoma A2780, non-small-cell lung cancer LXFA737 and LXFE937, and head and neck squamous cell carcinomas) were screened with starting tumor volumes in the range of either 130–150 mm3 (small tumors) or 270–380 mm3 (large tumors). Both albumin-binding prodrugs showed compelling anticancer efficacy compared to the parent drug auristatin E, inducing statistically significant long-term partial and/or complete tumor regressions. AE-Keto-Sulf07 displayed very good antitumor response over a wide dose range, 3.0–6.5 mg/kg (5–8 injections, biweekly). AE-Ester-Sulf07 was highly efficacious between 1.9 and 2.4 mg/kg (8 injections, biweekly) or at 3.8 mg/kg (4 injections, weekly), but caused cumulative skin irritation due to scratching and biting. In contrast at its MTD, auristatin E (0.3 mg/kg, 8 injections, biweekly) was only marginally active. In summary, AE-Keto-Sulf07 and AE-Ester-Sulf07 are novel acid-sensitive albumin-binding prodrugs demonstrating tumor regressions in all of the evaluated human tumor xenograft models thus supporting the stratagem that albumin can be used as an effective drug carrier for the highly potent class of auristatins.

Abstract

To support the 2012 Great Lakes Water Quality Agreement on reducing Lake Erie's phosphorus inputs, we integrated US and Canadian data to update and extend total phosphorus (TP) loads into and out of the St. Clair-Detroit River System for 1998–2016. The most significant changes were decreased loads from Lake Huron caused by mussel-induced oligotrophication of the lake, and decreased loads from upgraded Great Lakes Water Authority sewage treatment facilities in Detroit. By comparing Lake St. Clair inputs and outputs, we demonstrated that on average the lake retains 20% of its TP inputs. We also identified for the first time that loads from resuspended Lake Huron sediment were likely not always detected in US and Canadian monitoring programs due to mismatches in sampling and resuspension event frequencies, substantially underestimating the load. This additional load increased over time due to climate-induced decreases in Lake Huron ice cover and increases in winter storm frequencies. Given this more complete load inventory, we estimated that to reach a 40% reduction in the Detroit River TP load to Lake Erie, accounting for the missed load, point and non-point sources other than that coming from Lake Huron and the atmosphere would have to be reduced by at least 50%. We also discuss the implications of discontinuous monitoring efforts.

Abstract

Variability in SARS-CoV-2 susceptibility and COVID-19 disease severity between individuals is partly due to genetic factors. Here, we identify 4 genomic loci with suggestive associations for SARS-CoV-2 susceptibility and 19 for COVID-19 disease severity. Four of these 23 loci likely have an ethnicity-specific component. Genome-wide association study (GWAS) signals in 11 loci colocalize with expression quantitative trait loci (eQTLs) associated with the expression of 20 genes in 62 tissues/cell types (range: 1:43 tissues/gene), including lung, brain, heart, muscle, and skin as well as the digestive system and immune system. We perform genetic fine mapping to compute 99% credible SNP sets, which identify 10 GWAS loci that have eight or fewer SNPs in the credible set, including three loci with one single likely causal SNP. Our study suggests that the diverse symptoms and disease severity of COVID-19 observed between individuals is associated with variants across the genome, affecting gene expression levels in a wide variety of tissue types., Graphical abstract, D’Antonio et al. characterize associations between GWAS signals for COVID-19 disease and eQTLs in 69 human tissues to identify causal variants and their underlying molecular mechanisms. They show that diverse symptoms and disease severity of COVID-19 are associated with variants affecting gene expression in a wide variety of tissues.

Abstract

BackgroundThe optimal pulmonary revascularisation strategy in high-risk pulmonary embolism (PE) requiring implantation of extracorporeal membrane oxygenation (ECMO) remains controversial.MethodsWe conducted a systematic review and meta-analysis of evidence comparing mechanical embolectomy and other strategies, including systemic thrombolysis, catheter-directed thrombolysis or ECMO as stand-alone therapy, with regard to mortality and bleeding outcomes.ResultsWe identified 835 studies, 17 of which were included, comprising 327 PE patients. Overall, 32.4% were treated with mechanical pulmonary reperfusion (of whom 85.9% had surgical embolectomy), while 67.6% received other strategies. The mortality rate was 22.6% in the mechanical reperfusion group and 42.8% in the “other strategies” group. The pooled odds ratio for mortality with mechanical reperfusion was 0.439 (95% CI 0.237–0.816) (p=0.009; I2=35.2%)versusother reperfusion strategies and 0.368 (95% CI 0.185–0.733) (p=0.004; I2=32.9%) for surgical embolectomyversusthrombolysis. The rate of bleeding in patients under ECMO was 22.2% in the mechanical reperfusion group and 19.1% in the “other strategies” group (OR 1.27, 95% CI 0.54–2.96; I2=7.7%). The meta-regression model did not identify any relationship between the covariates “more than one pulmonary reperfusion therapy”, “ECMO implantation before pulmonary reperfusion therapy”, “clinical presentation of PE” or “cancer-associated PE” and the associated outcomes.ConclusionsThe results of the present meta-analysis and meta-regression suggest that mechanical reperfusion, notably by surgical embolectomy, may yield favourable results regardless of the timing of ECMO implantation in the reperfusion timeline, independent of thrombolysis administration or cardiac arrest presentation.

Abstract

In-situ coupled mechanical/electrical investigations on EPDM-based composite materials prepared using CB fillers of different (low and high) structure and at different concentrations have been carried-out by cyclic and continuous loading, with simultaneous measurements of stress, strain and electrical conductivity. By investigations in dependence on the strain amplitude and unloading rate, the relationship linking the evolution of the electrical conductivity during mechanical deformation to the mechanical Mullins effect is demonstrated. A characteristic electrical signature accompanying the mechanical Mullins effect is revealed, originating from a kinetic reorganisation of the CB fillers by competing mechanisms of de-percolation and re-percolation. Notable differences between the electrical and the mechanical Mullins effect are also found, in particular, in relation to the kinetics of the stabilization of properties after the first mechanical deformation cycle. Our study brings new light into understanding the coupled evolution of mechanical and electrical properties of elastomeric composite materials, with possible applications in monitoring the material properties under mechanical deformation by in-situ electrical measurements.
