Abstract
The global demand for valuable metals and minerals necessitates the exploration of alternative, sustainable approaches to mineral recovery. Seawater mining has emerged as a promising option, offering a vast reserve of minerals and an environmentally friendly alternative to land-based mining. Among the various techniques, Nanofiltration (NF) has gained significant attention as a preliminary treatment step in Minimum Liquid Discharge (MLD) and Zero Liquid Discharge (ZLD) schemes. This study focused on the potential of two underexplored commercial polyamide based NF membranes, Synder NFX and Vontron VNF1, with enhanced divalent over monovalent separation factors, in optimizing the extraction of magnesium hydroxide (Mg(OH)2) from seawater and seawater reverse osmosis (SWRO) brines. The research encompassed a thorough characterization of the membranes utilizing advanced physic-chemical analytical techniques, followed by rigorous experimental assessments using synthetic seawater and SWRO brine in concentration configuration. The findings highlighted the superior selectivity of NFX for magnesium recovery from SWRO brine and the promising concentration factors of VNF1 for seawater treatment. Cross-validation of experimental data with a mathematical model demonstrated the model's reliability as a process design tool in predicting membrane performance. A comprehensive techno-economic evaluation demonstrates the potential of NFX, operating optimally at 23 bar pressure and 70% permeate recovery rate, to yield an estimated annual revenue of 5.683 M€/yr through Mg(OH)2 production from SWRO brine for a plant with a nominal capacity of 0.8 Mm3/y. This research shed light on the promising role of NF membranes in enhancing mineral recovery taking benefit of their separation factors and emphasizes the economic viability of leveraging NF technology for maximizing magnesium recovery from seawater and SWRO brines.

Abstract
Purse-seine fishers using drifting fish aggregating devices (dFADs), mainly built with bamboo, plastic buoys, and plastic netting, to aggregate and catch tropical tuna, deploy 46,000-65,000 dFADs per year in the Pacific Ocean. Some of the major concerns associated with this widespread fishing device are potential entanglement of sea turtles and other marine fauna in dFAD netting; marine debris and pollution; and potential ecological damage via stranding on coral reefs, beaches, and other essential habitats for marine fauna. To assess and quantify the potential connectivity (number of dFADs deployed in an area and arriving in another area) between dFAD deployment areas and important oceanic or coastal habitat of critically endangered leatherback (Dermochelys coriacea) and hawksbill (Eretmochelys imbricata) sea turtles in the Pacific Ocean, we conducted passive-drift Lagrangian experiments with simulated dFAD drift profiles and compared them with known important sea turtle areas. Up to 60% of dFADs from equatorial areas were arriving in essential sea turtle habitats. Connectivity was less when only areas where dFADs are currently deployed were used. Our simulations identified potential regions of dFAD interactions with migration and feeding habitats of the east Pacific leatherback turtle in the tropical southeastern Pacific Ocean; coastal habitats of leatherback and hawksbill in the western Pacific (e.g., archipelagic zones of Indonesia, Papua New Guinea, and Solomon Islands); and foraging habitat of leatherback in a large equatorial area south of Hawaii. Additional research is needed to estimate entanglements of sea turtles with dFADs at sea and to quantify the likely changes in connectivity and distribution of dFADs under new management measures, such as use of alternative nonentangling dFAD designs that biodegrade, or changes in deployment strategies, such as shifting locations.

Abstract
OBJECTIVE Placental vascular reactivity (PlVR) indicates the ability of the placental vasculature to match blood supply to fetal demand. Many pregnancy disorders alter the characteristics of PlVR, resulting in suboptimal oxygen delivery, although current understanding is limited by the lack of non-invasive, repeatable methods to measure PlVR in utero. Our objective was to quantify PlVR by measuring the placental response to transient changes in maternal carbon dioxide (CO2) using blood-oxygen-level-dependent (BOLD) magnetic resonance imaging (MRI). We hypothesized that PlVR will increase with gestational age to meet the changing demands of a growing fetus, and that PlVR will be driven by a maternal response to changes in CO2 concentration. METHODS This was a cross-sectional study of 35 women with a healthy singleton pregnancy, of whom 31 were included in the analysis. The median gestational age was 32.6 (range, 22.6-38.4) weeks. Pregnant women were instructed to follow audiovisual breathing cues during a MRI scan. Maternal end-tidal CO2 (EtCO2) was measured concurrently with resting placental BOLD MRI for a total of 7-8 min. Preprocessing of magnetic resonance images consisted of manual delineation of placental anatomy and motion correction. In each placental voxel, vascular reactivity was computed using a coherence-weighted general linear model between MRI signal and EtCO2 stimulus. Global PlVR was computed as the mean of voxel-wise PlVR values across the placenta. RESULTS PlVR, quantified by the placental response to induced, transient changes in maternal CO2, was consistently measured in utero using BOLD MRI. PlVR increased non-linearly with advancing gestational age (P < 0.001) and was higher on the fetal side of the placenta. PlVR was associated positively with fetal brain volume after accounting for gestational age. PlVR did not show any significant associations with maternal characteristics. CONCLUSIONS We present, for the first time, a non-invasive paradigm to quantify PlVR in ongoing human pregnancies without the use of exogenous gases or contrast agents. Our findings suggest that PlVR is driven by a fetal response to changes in maternal CO2. Ease of translation to the clinical setting makes PlVR a promising biomarker for the identification and management of high-risk pregnancies. © 2023 The Authors.

Abstract
The roles and responsibilities of radiation therapists (RTTs) are many and varied. Professional expectations are influenced by the technology available, as well as the level of autonomy RTTs have in their daily practice. This professional range requires RTTs to possess a unique set of ever evolving skills, posing challenges from an educational perspective. Teaching these "advanced skills" has been the ambition the ESTRO Advanced Skills in Modern Radiotherapy course. In the 10th year of this course, the Faculty look back and reflect on how our programme has evolved and what it has achieved.

Abstract
Sleep spindle differences in adolescents with major depressive disorder (MDD) compared to healthy adolescents is an ongoing debate. Results mostly indicate decreased sleep spindle activity in adolescents with MDD. Given that sleep spindles predominate NREM and that acutely delaying the sleep period via a "sleep delay challenge" (SDC) increases non-rapid eye movement (NREM) sleep duration, it may be possible to increase spindle density in adolescents with MDD, which may provide a therapeutic benefit to depression symptoms. Here, we examined the impact of a SDC on spindle density and depression symptomology in adolescents with MDD (n = 66) and healthy controls (n = 62) tested across three nights: adaptation, normal sleep, and a SDC night which delayed bedtime by three hours. The results showed that; (1) there was no difference in spindle density between groups on the normal sleep night, (2) following the SDC, both males and females with MDD had a decrease in the frequency of slow spindles, while only females with MDD had an increase in the frequency of fast spindles, (3) acute SDC reduced depression symptoms in both groups, and (4) light sleep on the normal sleep night and slow spindle frequency at SDC predicted an 8 % improvement in depression symptoms, regardless of sex or MDD diagnosis. Taken together, these results suggest that; (a) spindles may be a useful biological marker of depression symptomatology regardless of clinical MDD diagnosis, and (b) that acute SDC may help alleviate depression symptoms in adolescents with MDD.

Abstract
BACKGROUND Genomic tests are a useful tool for adjuvant chemotherapy decision-making in the case of hormone receptor-positive (HR+), and human epidermal growth factor receptor 2-negative (HER2-) breast cancer with intermediate prognostic factors. Real-life data on the use of tests can help identify the target population for testing. METHODS French multicentric study (8 centers) including patients, all candidates for adjuvant chemotherapy for HR-positive, HER2-negative early breast cancer. We describe the percentage of tests performed outside recommendations, according to the year of testing. We calculated a ratio defined as the number of tests required to avoid chemotherapy for one patient, and according to patient and cancer characteristics. We then performed a cost-saving analysis using medical cost data over a period of 1 year from diagnosis, calculated from a previous study. Finally, we calculated the threshold of the ratio (number of tests required to avoid chemotherapy for one patient) below which the use of genomic tests was cost-saving. RESULTS A total of 2331 patients underwent a Prosigna test. The ratio (performed test/avoided chemotherapy) was 2.8 [95% CI: 2.7-2.9] in the whole population. In the group following recommendations for test indication, the ratio was 2.3 [95% CI: 2.2-2.4]. In the case of non-abidance by recommendations, the ratio was 3 [95% CI: 2.8-3.2]. Chemotherapy was avoided in 841 patients (36%) following the results of the Prosigna test. The direct medical costs saved over 1 year of care were 3,878,798€ and 1,718,472€ in the group of patients following test recommendations. We calculated that the ratio (performed test/avoided chemotherapy) needed to be under 6.9 for testing to prove cost-saving. CONCLUSION The use of genomic testing proved cost-saving in this large multicentric real-life analysis, even in certain cases when the test was performed outside recommendations.

Abstract
BACKGROUND Applying the Multi-Level Perspective (MLP) on socio-technical transitions, paired with the interdisciplinary framing approach, this paper investigates how incumbent actors of automobility in Germany framed the issue of a "transition of mobility and transport" ("Verkehrs/Mobilitätswende") in their public communication in 2020. We first identified representatives of industry, science, policy, and media, since the Verkehrs/Mobilitätswende and its implementation measures are contested among these actors. Employing qualitative content analysis, we then screened 325 public documents according to the elements of the framing approach problem definition, causal interpretation, moral evaluation, and treatment recommendation. RESULTS Findings show that most of the actors frame a transformation of transport and mobility as a necessity. Their arguments encompass environmental and climate-related issues as well as infrastructural problems for bikes and public transport caused by the hegemony of automobility. The actors propose a variety of solutions, primarily focusing on technical innovations for cars or on the expansion of different infrastructures to achieve a modal shift towards sustainable mobility. CONCLUSION This paper demonstrates that there is no common understanding of the problems and solutions to foster a mobility transition, as the diversity of problems and solutions proposed within the frame elements is high and complicates the prevailing implementation gap of the mobility transition. Therefore, MLP should be conceptually and methodologically bridged with the interdisciplinary framing approach, particularly with regard to the transition of mobility and transport.

Abstract
OBJECTIVE One genetic variant (rs1121980) of FTO gene has been related with body mass index and visceral adiposity. The objective of our study was to investigate the role of rs1121980 genetic variant of FTO gene on weight loss and metabolic changes secondary to a partial meal replacement (pMR) hypocaloric diet. PATIENTS AND METHODS We conducted an interventional study on 219 obese Caucasian subjects with body mass index (BMI) > 30 kg/m2. The subjects received two intakes per day of a normocaloric hyperproteic formula for 12 weeks. Adiposity and biochemical parameters (lipid profile, insulin, homeostasis model assessment (HOMA-IR) and glucose) were determined. RESULTS After the pMR diet, body weight, BMI, fat mass, waist circumference, blood pressure, total-cholesterol, LDL-cholesterol, triglyceride, fasting insulin levels and HOMA-IR decreased in both genotype groups. The improvements in adiposity parameters and some biochemical parameters (insulin, HOMA-IR, triglyceride levels) were bigger in non-T allele carriers than in T allele carriers. The percentage of patients who achieved 7.5% weight loss was higher in the non-T carriers (76.7% vs. 48.4%), also with a different average of weight loss (-12.3±0.3 kg vs. -5.9±0.5 kg: p=0.01). The odds ratio to achieve 7.5% of weight loss was (OR= 2.22, 95% CI=1.24-4.01; p=0.02). CONCLUSIONS Non-T allele carriers of rs1121980 show a higher magnitude of weight loss and improvement in adiposity parameters, insulin, HOMA-IR and triglyceride levels resulting from a pMR diet than T allele carriers.

Abstract
Today, glass and other similar dielectric materials are widely used in modern manufacturing. However, glass is a brittle and a heat sensitive material. Laser technology is used to process glass but quality and throughput are still a key issue. In the present paper, we investigate dual-wavelength double ultrashort laser pulses in order to control free electrons dynamics and subsequent ablation for fused silica processing, and further improve the understanding of this laser-material interaction. We used a high average power Yb-doped femtosecond laser source (100 W) with two optical lines exhibiting different pulse durations and wavelengths (500 fs at 515 nm; and 1 or 10 ps at 1030 nm) with various fluences and delays. The best configuration in terms of ablation efficiency is expected to take place when the green pulse first induces free electrons, followed by their heating by the red pulse. The obtained results are discussed in terms of optical transmission as well as ablated volume, and are compared with single pulse ablation. Our experimental results are supported by absorbed energy density calculations based on a model considering the two-color laser induced electron dynamics, including photoionization, laser heating of free electrons, and their recombination. We demonstrate that there is an optimal cooperating effect between the two sub-pulses for a 1-ps delay, nevertheless there is no beneficial effect in splitting the beam for optimizing fused silica ablation compared with the single-pulse green configuration.

Abstract
Background The COVID-19 syndemic reveals social and health inequalities, putting marginalized groups such as migrants at greater risk. Yet health systems fail to routinely monitor the health of migrants, refugees, and internally displaced persons. Our systematic review provides an up-to-date synthesis of the empirical evidence on COVID-19 infection risk, transmission, outcome of disease and risk of severe course of disease among migrant populations. It further aims to compile extant evidence on COVID-19 vaccination coverage among these groups, and on the effects of pandemic control measures on their health. Methods Following PRISMA guidelines, we registered a review protocol, searched 14 scientific databases and 4 pre-print servers using the WHO database of global literature on COVID-19, and hand-searched relevant websites for grey literature. The search period covers the time from 12/2019 to 11/30/2021. Articles in English, German and Spanish and all study designs were included. Results A total of 6966 references were identified for title and abstract screening. 518 records were screened in full-text, out of which 204 articles were included so far (conflict solving at full-text stage and data extraction are ongoing). Our review presents a broad landscape of different study designs, migrant populations and COVID-19 outcomes. Based on previous work, we expect to find a higher risk of infection in migrants and their disproportionate share among COVID-19 cases, and consolidate the (mental) health impacts of pandemic control measures. Our preliminary findings indicate a vast knowledge gap on vaccination coverage among migrant groups. Conclusions Two years into the syndemic, this review summarizes the global empirical evidence on the impact of the COVID-19 syndemic on migrant populations. With health systems often lacking related data, the review provides an important evidence base for the consideration of migrants in future pandemic preparedness policies. Key messages • The systematic review provides an up-to-date synthesis of the empirical evidence on COVID-19 among diverse migrant populations globally. • Knowledge on vaccination coverage in migrants remains patchy.

Abstract
Abstract
Background
Racial and socioeconomic disparities in the utilization of percutaneous structural heart disease interventions have been described in previous years, reflecting significant gaps. However, it is unclear if increased awareness has created meaningful changes in the utilization of left atrial appendage occlusion (LAAO) in underrepresented populations.
Purpose
We aim to further clarify current practices in the United States and answer questions to help guide further efforts in attenuating health disparities.
Methods
The National Inpatient Sample (NIS) was queried from 2016–2019 to identify all patients >65 years of age diagnosed with atrial fibrillation or atrial flutter who underwent left atrial appendage occlusion (LAAO) using the international classification of diseases, tenth revision clinical modification (ICD-10-CM) codes. We selected this age cutoff to minimize confounding bias from lack of insurance coverage as patients age 65 and older qualify for the Center of Medicare & Medicaid Services. We excluded patients with missing race information. In addition, we confined our analysis to patients of White, Black, and Hispanic ethnicity because the number of other races was insufficient for meaningful analysis. Multivariate linear and logistic regression analysis was performed to compare the odds of procedure utilization, in-hospital mortality, and significant periprocedural complications among study groups.
Results
We identified a total of 14,103,690 patients >65 years of age diagnosed with either atrial fibrillation or atrial flutter. Of those, 53,350 (0.38%) underwent LAAO. The mean age of the sample was 79±7.6 years. Compared to White patients, Black patients had lesser odds of undergoing LAAO when controlling for multiple confounders (AOR = 0.49, 95% CI 0.44–0.55, p<0.001). Among Hispanic patients, there was no statistically significant difference in the odds of undergoing LAAO compared to White patients. There was no statistically significant difference in mortality, vascular complications, non-home discharge, stroke, transient ischemic attack, pericardial tamponade, and length of stay in patients undergoing LAAO among different ethnicities.
Conclusions
Significant disparities, including procedure utilization and patient characteristics prior to the procedure, such as household income, still exist among Black patients compared to White patients undergoing the LAAO in the United States. Nevertheless, adjusted odds of in-hospital outcomes were similar among Black, Hispanic, and White patients. Further research is necessary to identify what mitigation strategies could be effective and what can be changed to close the remaining gap.

Abstract
Abstract
Background
Tricuspid regurgitation (TR) often occurs concomitantly with severe aortic stenosis. Post-operative worsening of tricuspid regurgitation has been observed after surgical and transcatheter aortic valve replacement (SAVR, TAVR) [1,2].
Purpose
Pre-procedural severe tricuspid regurgitation has been shown to be a predictor of all-cause mortality in patients undergoing transcatheter aortic valve replacement (TAVR) [3,4]. However, little is known about the incidence of worsening tricuspid regurgitation after SAVR and TAVR and the impact on post-procedural outcomes. This study aims to evaluate, characterize and compare the incidence of worsening TR after TAVR and SAVR.
Methods
Retrospective single-center study of patients undergoing Transcatheter and Surgical Aortic Valve Replacement for severe aortic stenosis between 2014 and 2020. Incidence of tricuspid regurgitation was noted on echocardiogram at baseline and 1 year after TAVR or SAVR. This study enrolled 430 patients in the TAVR group and 237 patients in the SAVR group. The SAVR group only included patients who underwent isolated SAVR without any other valve intervention. Patients with severe TR at baseline were excluded from the study. Progression of TR severity was defined as deterioration by at least 1 grade of severity compared to baseline on echocardiography. Multivariable logistic regression analysis was performed to identify associations with worsening TR.
Results
Mean age of TAVR patients was higher than the SAVR patients (79±9 vs 68±12 years, p<0.0001). TAVR patients also had a significantly higher EuroSCORE than the SAVR patients (8.0±7 vs 3.5±4, p<0.0001). TAVR group was more likely to have atrial fibrillation than the SAVR group (34% vs 24%, p=0.006). Baseline right ventricular dysfunction and right ventricular enlargement were significantly higher in the TAVR group compared to the SAVR group [9% vs 4%, (p=0.009) and 10% vs 6%, (p=0.04), respectively]. Progression of TR severity occurred in 21.8% (94/430) of TAVR patients and 31.2% (74/237) of SAVR patients. Majority of these patients progressed from absent TR to mild TR [13.2% (57) in TAVR group vs 19.8% (47) in SAVR group (p=0.02)]. 6.3% (27) of patients in the TAVR group and 8.8% (21) of patients in the SAVR group had mild to moderate worsening of TR (p=0.22). 1.63% (7) in the TAVR group and 2.1% (5) in the SAVR group had progression from moderate to severe TR (p=0.65). On multivariable analysis, SAVR (Odds ratio, 2.46 [CI, 1.6–3.7]) and age (Odds ratio, 1.03 [CI, 1.03–1.05]) were associated with worsening TR severity.
Conclusions
In this retrospective observational study, SAVR and age were found to be associated with worsening tricuspid regurgitation. Majority of these patients progressed from absent TR to mild TR after SAVR. Further studies are necessary to determine long term outcomes of worsening tricuspid regurgitation after TAVR and SAVR.

Abstract
Abstract
Background
Mitral regurgitation (MR) is a common valvular disorder associated with significant morbidity and mortality. Transcatheter mitral valve repair (TMVr) is a minimally invasive procedure indicated for the treatment of selected patients with moderate-severe or severe primary MR. Despite a lack of a universal definition, frailty has been associated with poor post-procedural outcomes. Albeit several trials have examined individual prognostic factors in this population, there is a paucity of data regarding the effect of frailty on in-hospital outcomes after TMVr.
Purpose
To further elucidate the association of frailty with in-hospital outcomes in patients undergoing TMVr.
Methods
The national inpatient sample (NIS) database, which is part of the Healthcare Cost and Utilization Project (HCUP), was queried from 2016 to 2019 to identify all who underwent TMVr. International classification of diseases, tenth revision clinical modification (ICD-10-CM) codes were used to divide patients into frail and non-frail study groups. Frailty was defined using Johns Hopkins Adjusted Clinical Groups diagnosis cluster for frailty. Multivariate linear and logistic regression analysis was performed to compare in-hospital mortality, hospital length of stay, non-home discharge, and iatrogenic cardiac complications among Frail and Non-Frail groups.
Results
A total of 30,660 patients who underwent TMVr were identified. The mean age was 76±11.6 years. Of those, 2,950 (9.6%) were identified as frail. The overall in-hospital mortality rate for the entire study population was 1.89%. Compared to non-frail patients, those identified as frail had greater odds of in-hospital mortality (AOR= 2.13, 95% CI 1.29–3.51, p<0.001) and non-home discharge (AOR= 4.34, 95% CI 3.54–5.32, p<0.001). However, there was no statistically significant difference in hospital length of stay and rates of iatrogenic cardiac complications.
Conclusions
Frailty models continue to be underutilized as a prognostic tool in clinical practice. After following HCUP guidelines, our analysis found that frailty is independently associated with increased in-hospital mortality and non-home discharge in patients undergoing TMVr. Therefore, we recommend that further efforts in incorporating frailty models in the pre-procedural assessment of patients undergoing TMVr should be sought along with a standardized predictive model for defining frailty.

Abstract
Abstract
Background
Takotsubo cardiomyopathy (TCM) is a syndrome characterized by reversible left-ventricular regional systolic dysfunction in the absence of obstructive coronary artery disease (CAD). The presence of left bundle branch block (LBBB) has been described as an independent predictor of mortality in patients with CAD. One study using the National Inpatient Sample (NIS) for 2016 found that the presence of LBBB was associated with worse outcomes in patients with TCM.
Purpose
To better clarify the association between LBBB and various in-hospital outcomes in patients with TCM.
Methods
The NIS database was queried from 2016–2019 to identify all admissions with a primary diagnosis of TCM that had a cardiac catheterization to improve the specificity of the diagnosis. International classification of diseases, tenth revision clinical modification (ICD-10-CM) codes were used to divide patients based on the presence or absence of LBBB. A 1:3 propensity score matching based on age, race, gender, and risk factor stratification was used to reduce selection bias. Multivariate linear and logistic regression analysis was performed to compare various outcomes among both groups.
Results
A total of 27,125 patients admitted with a primary diagnosis of TCM that also underwent diagnostic coronary angiography were identified. In the study sample, 955 (3.5%) were determined to have a LBBB. After calculating propensity scores, 955 patients with LBBB were paired to 2,865 patients without LBBB. LBBB was associated with higher rates of ventricular arrhythmias (AOR=3.098, 95% CI 1.483–6.471, p=0.003); however, it was not statistically associated with cardiogenic shock, sudden cardiac arrest (SCA), acute kidney injury, acute heart failure, and hospital length of stay. In addition, there was no statistical difference in intra-hospital mortality.
Conclusions
LBBB is associated with left ventricular dyssynchrony. It has been proposed that intraventricular dyssynchrony might be a predisposing factor for ventricular arrhythmias (VA) and SCA. Several trials have demonstrated that cardiac resynchronization therapy alone (i.e., without defibrillation) reduces the rate of VA and SCA. The mechanism for this improvement is unclear but may be related to hemodynamic improvement from ventricular synchrony in heart failure (HF). In fact, LBBB has been reported as an independent risk factor for all-cause mortality and SCA at one year in patients with HF. Our analysis did not find any significant association between LBBB and SCA but did find an association with VA. Moreover, there were not enough events of intra-hospital mortality to assess a possible association between LBBB and mortality. Therefore, a prospective study with a longer follow-up would be needed to clarify the role of LBBB in mortality and establish causality between LBBB and VA in patients with TCM.

Abstract
BackgroundOsteoporosis is the most common cause of fractures. The lifetime risk of fracture after age 50 is 40% for women and 13% for men.ObjectivesPatients with rheumatological diseases are at greater risk for the development of osteoporosis, either due to the natural history of their disease or due to the side effects of the medications used. We proposed to carry out this study.MethodsRetrospective study aimed at determining the presence of risk factors in patients over 50 years of age who attend the Rheumatology service of a hospital in Venezuela during a follow-up from January 2010 to December 2020 in order to know these risk factors and thus generate strategies that allow better orienting the care of these patients.ResultsThe main group of patients was constituted by the female gender and the ages between 50 and 65 years. The main rheumatological pathology was rheumatoid arthritis, followed by Lupus, Osteoarthritis in 3 place and finally in the last box other entities other than those indicated.Graph 1. Prevalence of Osteoporosis due to rheumatological pathologies.ConclusionThe 2 main risk factors for the development of osteoporosis were the use of steroids and obesity. The main type of osteoporosis of the 2 categories described was non-severe. The main group of rheumatological patients most associated with osteoporosis were those with rheumatoid arthritis. 12% of the patients with rheumatic disease and osteoporosis did not have appropriate therapy.References[1]Tella SH, Gallagher JC.

Abstract
OBJECTIVE One SNP in exon 9 (r5883) has been involved with high risk of cardiovascular disease in hypertensive subjects. The goal of the present study was to test the role of this genetic variant on lipid levels and Metabolic Syndrome (MS) in menopausal obese females. PATIENTS AND METHODS The study enrolled a sample of 112 menopausal obese females. Measurements of adiposity parameters, blood pressure, fasting blood glucose, insulin concentration, insulin resistance (HOMA-IR), lipid profile, C reactive protein and prevalence of MS were recorded. Genotype of CETP gene polymorphism (rs5883) was studied. RESULTS The distribution of the rs5883 polymorphism in this menopausal obese population was 83.9% (n=94) (CC), 15.2% (n=17) (CT) and 0.9% (n=1) (TT). Adiposity parameters, blood pressure, fasting glucose levels, insulin levels, HOMA-IR, C reactive protein, total cholesterol, LDL-cholesterol and triglycerides were similar in both genotype groups (CC vs. CT+TT). Moreover, HDL cholesterol (8.5+1.2 mg/dl; p=0.01) and ratio total cholesterol/HDL-cholesterol (0.5±0.2; p=0.04) were higher in T allele carriers (dominant model). MS percentage was similar in both genotypes (37.6% vs. 27.2%; p=0.43). Logistic regression analysis showed a decreased risk of low-HDL cholesterol in T allele carriers (OR=0.18, 95% CI=0.02-0.77, p=0.03) after adjusting by dietary fatty acid intakes, body mass index and age. CONCLUSIONS The results reported here support that CETP variant rs5883 is related with HDL-cholesterol levels and ratio total cholesterol/HDL-cholesterol.

Abstract
Abstract
Introduction
Frailty studies focused on patients with infective endocarditis (IE) are scarce and its potential impact on patient outcomes is not well known.
The aim of this study is to describe the clinical profile and prognosis of elderly patients with IE, comparing patients who met the frailty criteria versus those who did not.
Methods
A total of 121 cases of confirmed IE were consecutively collected in three tertiary hospitals between 2017 and 2019. The patients were classified into two groups: Group I (n=49), patients with IE who met the Frail criteria for frailty, and Group II (n=72), those patients without frailty by this scale.
Results
The median age of our cohort was 77 years (69–82), and 62.8% were men. Frail patients were older than those in Group II, as shown in Table 1.
Regarding comorbidity, chronic anemia (40.8% vs 25%; p<0.060) was more common in Group I, as well as rheumatic manifestations at admission (12.2% vs 1.4%; p=0.014).
The most frequently isolated microorganisms were S. aureus (n=25), coagulase negative staphylococci (n=25), viridans group streptococci (n=14), and enterococci (n=14). Enterococci (16.3% vs 8.3%, p=0.177) and non-viridans streptococci (10.2% vs 2.8%); p=0.086) were more frequent in frail patients.
Vegetation (79.6% vs 80.6%; p=0.896) and periannular complications (24.5% vs 29.2%; p=0.571) were similar in both groups. No significant differences were found regarding the location of the infection.
The incidence of in-hospital complications was similar between both groups. Frail patients underwent surgery less frequently than those in Group II, and had higher predicted mortality on surgical risk scale scores. However, the percentage of patients who met the surgical criteria and were considered inoperable was similar (33.3% vs 26.2%; p=0.415). In-hospital mortality was similar in both groups. When analyzing in-hospital mortality according to the therapeutic strategy in Group I, a mortality of 34.5% was observed in frail patients with conservative medical treatment, compared to 47.1% in those patients who underwent surgery in the same group.
One third of our patients received outpatient antibiotic treatment, being significantly more frequent in Group I (39.6% vs 29.0%; p=0.232).
Conclusions
The elderly patients with IE and frailty criteria were older and more frequently had rheumatic symptoms at admission. Enterococci and non-viridans streptococci were isolated more frequently than in non-frailty patients. Surgery was less performed among frail patients, who had a higher predicted surgical risk. Although complications and in-hospital mortality were similar between both groups, in the group of frail patients, those with conservative management showed lower mortality compared to surgery.

Abstract
Abstract
Background
Spontaneous coronary artery dissection (SCAD) is a common, non-atherosclerotic cause of myocardial infarction (MI). While conservative therapy is preferred in most cases, its role among those presenting as ST-elevation myocardial infarction (STEMI) remains undefined.
Purpose
We aimed to explore outcomes of SCAD causing STEMI, stratifying cases by involved coronary artery and revascularization status.
Methods
We used the Nationwide Readmission Database (2015–2018) to identify patients hospitalized with STEMI by using ICD-10-Clinical modification codes, and then stratified them into SCAD or no-SCAD groups. Each group was further subdivided by involved coronary artery (i.e., left main, left anterior descending, left circumflex, or right coronary artery), and if revascularization (i.e., percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG)) was performed. We excluded patients >55 years old or with iatrogenic dissection. The age restriction allows us to compare a similarly aged group of patients. The primary outcome was in-hospital mortality. Cardiogenic shock, acute kidney injury, mechanical complications, length of stay, and 30-day readmission for all-cause, heart failure or MI were secondary outcomes.
Results
Of the 17,556 patients with STEMI identified, 338 (1.9%) had SCAD. Patients with SCAD were younger (median age (IQR) 46.0 (33–90) vs 49.0 (41–57); p<0.001) and more likely to be female (67% vs 21.6%, p<0.001). They were less likely to have PCI (55.3% vs. 80.7%; p<0.001), more likely to undergo CABG (4.7% vs 1.3%; p<0.001), with left main and left anterior descending coronary arteries more often affected (2.4% vs 1.1%, and 53.3% vs 48.6%; p for both =0.05, respectively). In-hospital mortality did not differ between groups (3.6% vs 3.3, p=0.81). Revascularization was associated with lower in-hospital mortality among no-SCAD patients (2.6% vs 7.0%, p<0.001), but not among SCAD patients (4.0% vs 3.1%, p=0.76) even when stratified by involved coronary artery. Revascularization among SCAD patients was associated with lower 30-day readmission rates for MI (0.0% vs 2.8%, p=0.05). SCAD patients were less likely to have acute kidney injury (6.5% vs 11.2%, p=0.01), but had a longer length of stay (median (IQR) 3.0 (1.0–6.0) vs 2.0 (1.0–4.0), p<0.001). Both groups had similar rates of cardiogenic shock (11.8% vs 10.6%, p=0.56), mechanical complications (0.6% vs 0.3%, p=0.22), and 30-day readmission rates for all-cause, and heart failure.
Conclusion
In-hospital mortality did not differ between patients with STEMI due to SCAD or no-SCAD. Although revascularization was not associated with lower in-hospital mortality among SCAD patients (regardless of involved coronary artery), their 30-day readmission rate for MI was lower suggesting further studies are warranted to explore patient subsets of SCAD that may benefit from revascularization.

Abstract
The distribution of the spinetail devil ray Mobula mobular in the eastern tropical Atlantic remains poorly known compared to the Pacific and Indian Oceans. We used fishery-dependent data and generalized additive models to examine the environmental characteristics associated with the presence of M. mobular in the eastern Atlantic Ocean. Results revealed that the distribution of M. mobular is significantly associated with seasonal upwelling systems in coastal and pelagic areas. Our model predicted the presence of the species in areas where there is evidence of its occurrence, such as the Angolan upwelling system and the coast of Ghana. In addition, our model predicted new hotspot areas, including locations around the Mauritanian upwelling system, the Guinea coast, offshore Ghana and the south coast of Angola and Brazil, where sample sizes are limited. Those areas, as well as the environmental preferences depicted by the model, provide valuable information about the habitat and ecology of the spinetail devil ray. Future research lines derived from this study, as well as its limitations, are discussed. Furthermore, in light of our results we discuss the improvements that are needed to contribute to the conservation and management of this vulnerable species.

Abstract
The photocatalytic degradation of simazine (SIM) was investigated using zinc oxide/graphene oxide (ZnO/GO) composite materials under visible light irradiation. The reaction kinetics was studied to optimize the reaction parameters for efficient degradation of SIM. Batch studies were performed to investigate the effects of initial reaction pH, the loading of the ZnO onto GO, and mass of catalyst on the removal of SIM from aqueous solution. A pH of 2 was determined to be the optimal reaction pH for the different ZnO-loaded GO catalysts. In addition, a mass of 40 mg of catalyst in the reaction was observed to be the most effective for the catalysts synthesized using 20 and 30 mmol of Zn2+ ions; whereas a mass of 10 mg was most effective for the ZnO/GO composite material synthesized using 10 mmol Zn2+ ions. The reaction was observed to follow a second-order kinetics for the degradation process. Furthermore, the synthesized ZnO/GO composite catalysts resulted in higher reaction rates than those observed for pure ZnO. The 30 mmol ZnO/GO composite expressed a rate of SIM degradation ten times greater than the rate observed for pure ZnO, and sixty-two times greater than the rate of photolysis. In addition, the catalyst cycling exhibited a constant photocatalytic activity for the ZnO/GO composite over three reaction cycles without the need of a conditioning cycle.

Abstract
INTRODUCTION Latinos are at higher risk of colorectal cancer (CRC) mortality than non-Hispanic Whites due, in part, to disparities in cancer screening. There is a need to evaluate community-based CRC interventions as they may reach underinsured communities and those at highest risk for CRC. This article describes the development of a group-based CRC intervention (Juntos contra el Cancer). METHOD Purposive sampling was used to recruit Latino men and women aged 50 to 75 years not-up-to-date with CRC screening. The development of the intervention was guided by the socioecologic framework, a community needs assessment, literature reviews, five focus groups (n = 39) from the target community and feedback from a Community Advisory Board. RESULTS Findings from focus groups suggested that a group-based, promotor or community health worker (CHW) led, cancer prevention education with linkages to care would address barriers to CRC screening. CONCLUSION Development of community-based CRC screening interventions should be informed by early and sustained community engagement. Interventions led by CHWs with linkages to care are feasible and can reach populations not connected to health care settings.

Abstract
BACKGROUND SPLIT was founded in 1995 in order to collect comprehensive prospective data on pediatric liver transplantation, including waiting list data, transplant, and early and late outcomes. Since 2011, data collection of the current registry has been refined to focus on prospective data and outcomes only after transplant to serve as a foundation for the future development of targeted clinical studies. OBJECTIVE To report the outcomes of the SPLIT registry from 2011 to 2018. METHODS This is a multicenter, cross-sectional analysis characterizing patients transplanted and enrolled in the SPLIT registry between 2011 and 2018. All patients, <18 years of age, received a first liver-only, a combined liver-kidney, or a combined liver-pancreas transplant during this study period. RESULTS A total of 1911 recipients from 39 participating centers in North America were registered. Indications included biliary atresia (38.5%), metabolic disease (19.1%), tumors (11.7%), and fulminant liver failure (11.5%). Greater than 50% of recipients were transplanted as either Status 1A/1B or with a MELD/PELD exception score. Incompatible transplants were performed in 4.1%. Kaplan-Meier estimates of 1-year patient and graft survival were 97.3% and 96.6%. First 30 days of surgical complications included reoperation (31.7%), hepatic artery thrombosis (6.3%), and portal vein thrombosis (3.2%). In the first 90 days, biliary tract complications were reported in 13.6%. Acute cellular rejection during first year was 34.7%. At 1 and 2 years of follow-up, 39.2% and 50.6% had normal liver tests on monotherapy (tacrolimus or sirolimus). Further surgical, survival, allograft function, and complications are detailed.

Abstract
Abstract
Background
High oxidized phospholipid-apolipoprotein B-100 (OxPL-apoB) levels are associated with an increased risk for coronary heart disease (CHD). Genetic PCSK9 loss-of-function (LOF) variants result in life-long lower levels of LDL-C and lipoprotein(a) and reduced CHD risk, but the association with OxPL-apoB is unknown.
Purpose
To estimate the association between PCSK9 LOF variants and OxPL-apoB levels among black adults.
Methods
Genotyping for LOF variants (Y142X and C679X) was conducted for 10,196 black Reasons for Geographic And Racial Differences in Stroke study participants. OxPL-apoB was measured using antibody E06 for all participants with LOF variants (n=241) and randomly selected participants, matched at a 1:3 ratio, without LOF variants (n=723). Low OxPL-apoB was defined as the bottom quartile of the population distribution (<1.6 nM). Prevalence ratios (PR) and 95% confidence intervals (CI) were calculated for the association between PCSK9 LOF variants and low OxPL-apoB levels adjusting for age, sex, and estimated glomerular filtration rate.
Results
Adults with versus without PCSK9 LOF variants had lower LDL-C and lipoprotein(a) and were less likely to be taking a statin. (Table) A higher proportion of adults with versus without PCSK9 LOF variants had low OxPL-apoB levels (30.3 vs 23.4, p=0.03). After adjustment for covariates, the PR of low OxPL-apoB was increased for participants with compared to without LOF variants (PR 1.31, 95% CI 1.00, 1.72).
Characteristics of REGARDS participants PCSK9 loss-of-function variant p-value Yes (n=241) No (n=723) Age, years, mean (SD) 63.7 (9.2) 63.8 (8.6) 0.81 Female, % 61.4 60.6 0.82 Diabetes, % 34.4 27.4 0.04 LDL-C, mg/dL, mean (SD) 85 (32) 118 (37) <0.001 Lp(a), nmol/L, median (25th, 75th percentile) 63.2 (30.4, 119.6) 80.4 (39.7, 138.4) 0.02 Statin use, % 13.3 30.4 <0.001 OxPL-apoB <1.6 nM, % 30.3 23.4 0.03 Abbreviations: LDL-C, low-density lipoprotein cholesterol; Lp(a), lipoprotein(a); LOF, loss-of-function; nM, nanomolar; OxPL-apoB, oxidized phospholipids on apolipoprotein B-100; PCSK9, proprotein convertase subtilisin/kexin type-9; REGARDS, REasons for Geographic And Racial Differences in Stroke; SD, standard deviation.
Conclusion
Among black adults, PCSK9 LOF variants were associated with lower OxPL-apoB levels.

Abstract
BACKGROUND Acute Ischemic Stroke (AIS) represents an economic challenge for health systems all over the globe. Changes of neuroactive steroids have been found in different neurological diseases. We have previously demonstrated that old patients with AIS show changes of plasma cortisol and estradiol concentrations, in that increased steroid levels are associated with a deterioration of neurological status and a worse cognitive decline. OBJECTIVE The present study assessed in patients with AIS if changes of behavior, Brain-Derived Neurotrophic Factor (BDNF) and Nitrites (NO-2) bear a relationship with the degree of hypercortisolism. METHODS We recruited patients hospitalized within the first 24 hours of AIS. Subjects were divided into two groups, each one composed of 40 control subjects and 40 AIS patients, including men and women. The neurological condition was assessed using the National Institute of Health Stroke Scale (NIHSS) and the cognitive status with the Montreal Cognitive Assessment (MoCA). The emotional status was evaluated using the Montgomery-Asberg Depression Rating Scale (MADRS), whereas the Modified Rankin Scale (MRS) was used to determine the functional condition. BDNF and NO-2 plasma levels were measured by ELISA and the Griess reaction method, respectively. RESULTS We found that in AIS patients, increased plasma cortisol was negatively correlated with plasma BDNF and NO-2 levels, neurological condition, cognition, functional responses and emotional status, suggesting a relationship between the declines of clinical, behavioral and blood parameters with stress-induced cortisol elevation. CONCLUSION Nitrites and BDNF may represent potential biomarkers for cortisol negative effects on the area of cerebral ischemia and penumbra, potentiating ischemic cell damage.

Abstract
BACKGROUND In this work, we assessed the efficacy and safety of brentuximab vedotin (BV) plus ESHAP (BRESHAP) as second-line therapy for Relapsed/Refractory Hodgkin lymphoma (RRHL) to improve the results before autologous stem-cell transplantation (ASCT). PATIENTS AND METHODS This was a multicenter, open-label, phase I-II trial of patients with RRHL after first-line chemotherapy. Treatment had three 21-day cycles of etoposide, solumedrol, high-dose AraC, and cisplatin. BV was administered at three dose levels (0.9, 1.2, and 1.8 mg/kg) intravenous on day ‒1 to 3 + 3 cohorts of patients. Final BV dose was 1.8 mg/kg. Responding patients proceeded to ASCT, followed by three BV courses (1.8 mg/kg, every 21 days). Main end points for evaluation were maximum tolerable dose and overall and complete response (CR) before ASCT. RESULTS A total of 66 patients were recruited (median age 36 years; range 18-66): 40 were primary refractory, 16 early relapse and 10 late relapse. There were 39 severe adverse events were reported in 22 patients, most frequently fever (n = 25, 35% neutropenic), including 3 deaths. Grade 3-4 hematological toxicity presented in 28 cases: neutropenia (n = 21), thrombocytopenia (n = 14), and anemia (n = 7). Grade ≥3-4 extrahematological adverse events (≥5%) were non-neutropenic fever (n = 13) and hypomagnesaemia (n = 3). Sixty-four patients underwent stem-cell mobilization; all collected >2×10e6/kg CD34+ cells (median 5.75; range 2.12-33.4). Overall response before transplant was 91% (CI 84% to 98%), including 70% (CRs 95% CI 59% to 81%). 60 patients were transplanted with no failure engraftments. Post-transplant response was CR in 49 patients (82% CI 73% to 91%) and partial responses in six (10% CI 5% to 15%). After a mean follow-up of 27 months, the 30-month time to treatment to failure was 74% (95% CI 68% to 80%), progression-free survival 71% (95% CI 65% to 77%), and overall survival 91% (CI 84% to 98%). CONCLUSION BRESHAP looks a safe and effective pre-transplant induction regimen, does not jeopardize transplant and allows long-term remissions and survival.
