Abstract
AIMS Evaluation of left and right ventricular longitudinal systolic function may enhance risk stratification following aortic valve replacement (AVR). The study objective was to evaluate the changes in left and right ventricular longitudinal systolic function and RV-pulmonary artery (RV-PA) coupling from baseline to 30-days and 1-year after aortic valve replacement (AVR). METHODS AND RESULTS LV longitudinal strain (LS), tricuspid annulus plane systolic excursion (TAPSE), and RV-PA coupling were evaluated in patients from the PARTNER-2A surgical AVR (SAVR) arm (n=985) and from the PARTNER-2 SAPIEN-3 registry (n=719). TAPSE and RV-PA coupling decreased significantly following SAVR, but remained stable following TAVR. Lower LV LS, TAPSE, or RV-PA coupling at baseline were associated with increased risk of the composite of death, hospitalization, and stroke at 5-years (Adjusted-HRs for LV LS<15%: 1.24 95%CI 1.05-1.45, p=0.001; TAPSE<14mm: 1.44 95%CI 1.21-1.73, p<0.001; RV/PA coupling<0.55mm/mmHg: 1.32 95% CI 1.07-1.63, p=0.011). Reduced TAPSE at baseline was the most powerful predictor of the composite endpoint at 5-years. Patients with LV ejection fraction <50% at baseline had increased risk of the primary endpoint with SAVR (HR: 1.34, 95%CI 1.08-1.68, p=0.009) but not with TAVR (HR: 1.12, 95%CI 0.88-1.42). Lower RV-PA coupling at 30-days showed the strongest association with cardiac mortality. CONCLUSION SAVR but not TAVR was associated with a marked deterioration in RV longitudinal systolic function and RV-PA coupling. Lower TAPSE and RV-PA coupling at 30-days were associated with inferior clinical outcomes at 5-years. In patients with LVEF<50%, TAVR was associated with superior 5-year outcomes.

Abstract
BACKGROUND Induced pluripotent stem cell (iPSC)-derived cell therapies are an interesting new area in the field of regenerative medicine. One of the approaches to decrease the costs of iPSC-derived therapies is the use of allogenic homozygous human leukocyte antigen (HLA)-matched donors to generate iPSC lines and to build a clinical-grade iPSC bank covering a high percentage of the Spanish population. METHODS The Spanish Stem Cell Transplantation Registry was screened for cord blood units (CBUs) homozygous for the most common HLA-A, HLA-B and HLA-DRB1 haplotypes. Seven donors were selected with haplotypes covering 21.37% of the haplotypes of the Spanish population. CD34-positive hematopoietic progenitors were isolated from the mononuclear cell fraction of frozen cord blood units from each donor by density gradient centrifugation and further by immune magnetic labeling and separation using purification columns. Purified CD34 + cells were reprogrammed to iPSCs by transduction with the CTS CytoTune-iPS 2.1 Sendai Reprogramming Kit. RESULTS The iPSCs generated from the 7 donors were expanded, characterized, banked and registered. Master cell banks (MCBs) and working cell banks (WCBs) from the iPSCs of each donor were produced under GMP conditions in qualified clean rooms. CONCLUSIONS Here, we present the first clinical-grade, iPSC haplobank in Spain made from CD34 + cells from seven cord blood units homozygous for the most common HLA-A, HLA-B and HLA-DRB1 haplotypes within the Spanish population. We describe their generation by transduction with Sendai viral vectors and their GMP-compliant expansion and banking. These haplolines will constitute starting materials for advanced therapy medicinal product development (ATMP).

Abstract
Coronal holes are areas on the Sun with open magnetic field lines. They are a source region of the solar wind, but how the wind emerges from coronal holes is not known. We observed a coronal hole using the Extreme Ultraviolet Imager on the Solar Orbiter spacecraft. We identified jets on scales of a few hundred kilometers, which last 20 to 100 seconds and reach speeds of ~100 kilometers per second. The jets are powered by magnetic reconnection and have kinetic energy in the picoflare range. They are intermittent but widespread within the observed coronal hole. We suggest that such picoflare jets could produce enough high-temperature plasma to sustain the solar wind and that the wind emerges from coronal holes as a highly intermittent outflow at small scales.

Abstract
Magnetic reconnection is a key mechanism involved in solar eruptions and is also a prime possibility to heat the low corona to millions of degrees. Here, we present ultra-high-resolution extreme ultraviolet observations of persistent null-point reconnection in the corona at a scale of about 390 km over one hour observations of the Extreme-Ultraviolet Imager on board Solar Orbiter spacecraft. The observations show formation of a null-point configuration above a minor positive polarity embedded within a region of dominant negative polarity near a sunspot. The gentle phase of the persistent null-point reconnection is evidenced by sustained point-like high-temperature plasma (about 10 MK) near the null-point and constant outflow blobs not only along the outer spine but also along the fan surface. The blobs appear at a higher frequency than previously observed with an average velocity of about 80 km s-1 and life-times of about 40 s. The null-point reconnection also occurs explosively but only for 4 minutes, its coupling with a mini-filament eruption generates a spiral jet. These results suggest that magnetic reconnection, at previously unresolved scales, proceeds continually in a gentle and/or explosive way to persistently transfer mass and energy to the overlying corona.

Abstract
OBJECTIVES The main objective of this study was to analyze French general practitioners' (GP) online prescriptions for suspected acute cystitis using a single nationwide teleconsultation platform. PATIENTS AND METHODS First, a descriptive study of management for suspected cystitis was conducted from the 1st of January to the 31st of December 2020. After which, following pedagogical intervention, a pre/post descriptive analysis of the antibiotics prescribed was carried out. RESULTS Some 496,041 teleconsultations (TCs) were carried out in 2020 on the Qare platform. Among them, 15089 TCs for cystitis with ICD-10 encoding (N30) were analyzed. Fosfomycin trometamol was the most prescribed antibiotic (n=10297, 69%), while fluoroquinolones (n=1568, 10.6%) were the second. Urine test strip was prescribed in 3157 (20%) and urine culture in 7033 (47%) of the TCs. July-August 2020 and July-August 2021 were compared and while a significant drop in fluoroquinolone prescriptions and a major increase in Fosfomycin trometamol were observed, there was no change in the prescriptions of urine culture. An average antibiotic conformity rate of 61.5% was observed before the intervention, and 68.8% afterwards. CONCLUSIONS Cystitis is a recurrent reason for remote consultation. The study demonstrated sizable over-prescription of urine culture, ultrasound, and fluoroquinolones. Intervention should be improved and strengthened to guarantee continuous training and awareness of GP's on appropriate cystitis prescriptions in telemedicine.

Abstract
Teleconsultation has become a new means of using care which has taken off significantly since the COVID crisis, The pooling of the technological environment within the TC makes it possible to set up practice reviews by reusing the data collected. Our aim was to evaluate the relevance of antibiotic therapy during teleconsultations carried out on the national teleconsultation platform "Qare" in 4 common infections. 143,428 TCs with structured prescriptions were analyzed, with an appropriate prescription in more than 82% of cases, higher than in the literature. The use of data makes it possible to quickly assess practices and inform doctors to improve their practices.

Abstract
Introduction The COVID-19 pandemic generated a health emergency and led to the adoption of different measures, including home quarantine and social isolation, which, as we have seen, has had an impact on the mental health of the majority of citizens, with the possibility of psychiatric disorders appearing. in people without prior mental illness, such as acute decompensations in patients with known disorders, more vulnerable to environmental stressors. Objectives Learn and rethink alarm signals in extreme situations such as the one experienced in recent months, as well as observe the impact, negative in many cases, but positive in others, of the patients we treat daily. Methods Description through brief clinical cases of the impact of the COVID-19 pandemic on psychotic patients and the decompensation that it has entailed, including due to confinement measures and social isolation, associated with over-information through the media, chaos initial and the uncertainty that it caused and the associated fear. Results Restrictions as a result of COVID-19 have played a very relevant role as an external stressor for the appearance of psychopathological alterations, including psychotic symptoms. In addition, people who suffer from psychosis or at risk of psychotic disorder can be especially affected and trigger acute psychopathology with social isolation, loss of daily routines, unemployment, homelessness. Conclusions These cases are an example that shows the need for an early and effective approach to the rise in mental illnesses in circumstances of this caliber.

Abstract
BackgroundNon-alcoholic fatty liver disease (NAFLD), the most common cause of liver disease, has a prevalence of about 25% in the general population. It increases mortality and comorbidity in patients with immune-mediated inflammatory diseases.ObjectivesThe main objective is to estimate the prevalence of NAFLD in three of the most common rheumatologic pathologies: rheumatoid arthritis (RA), axial spondyloarthritis (SpA-ax) and psoriatic arthritis (PsA). As a secondary objective, the possibility of finding associated risk factors in this group of subjects that may imply a higher risk of developing NAFLD is proposed.MethodsWe conducted a prospective single center observational study which included patients diagnosed with RA, EspA-ax, and PsA attended in the Rheumatology department of a tertiary hospital from January to April 2021. Anthropometric parameters, history related to cardiovascular risk factors and disease activity at the time of the visit were collected. Additionally, blood tests and transitional elastography were performed in all patients and the presence of NAFLD was assessed by the fatty liver index (FLI) scale. Different variables were considered to study their association with NAFLD.Results90 patients were included: 28 diagnosed with RA, 36 with EspA-ax and 26 with PAs. 41.1% were male (age range: 27-79 years). Patients with previous liver disease were excluded from the study. 22 (27.2%) patients had NAFLD measured by FLI ≥ 60. No significant differences in prevalence of hepatic steatosis were found between the 3 groups, although values were higher in patients with PsA.The variables that were significantly associated with the development of NAFLD in our cohort were: body mass index (BMI), abdominal perimeter, blood glucose level, HOMA-IR (Homeostatic Model Assessment for Insulin Resistance), HDL, TG, GGT, ferritin and uric acid levels. The rest of the variables studied did not show statistically significant differences (Table 1).Table 1.NO STEATOSIS (FLI<60)n=59STEATOSIS (FLI>60)n=22MeanStandard deviationMeanStandard deviationpBMI24,523,0030,292,77< 0,001Abdominal perimeter86,3410,01106,828,55< 0,001Age52,9312,8757,598,240,1185Glucose78,648,3790,6419,690,0002Insulin8,8310,1212,406,660,1302HOMA1,752,022,761,700,0500HbA1c5,350,455,690,640,0096Total cholesterol190,9829,46201,4138,530,1977HDL64,8817,6655,5911,550,0249LDL110,4428,45120,0036,210,2163TG81,1232,42128,5055,52< 0,001GPT25,8330,7337,1819,820,1116GOT27,2023,4926,8210,690,9413GGT20,8017,6649,9538,46< 0,001Creatinin0,750,190,840,180,0583Uric acid4,781,305,911,140,0007Ferritina121,75111,30208,00140,170,0050PCR2,894,552,672,330,8307ConclusionHepatic steatosis was present in 27.2% of patients vs 25% estimated prevalence in the general population.

Abstract
BACKGROUND Moderate or worse paravalvular regurgitation (PVR) post transcatheter aortic valve replacement (TAVR) is associated with increased mortality. The mechanisms by which this occurs are not fully understood. AIMS The aim of this study was to determine the mechanism by which PVR leads to worse outcomes. METHODS A total of 1,974 intermediate-risk patients who received TAVR in the PARTNER 2 trial and registries were grouped by PVR severity. Clinical and echocardiographic outcomes were compared. RESULTS Overall 1,176 (60%) patients had none/trace, 680 (34%) had mild, and 118 (6%) had ≥moderate PVR. At two years, ≥moderate PVR patients had increased risks of all-cause (HR 2.33 [1.41-3.85], p-value=0.001) and cardiovascular death (HR 3.30 [1.74-6.28], p-value <0.001), rehospitalisation (HR 2.68 [1.57-4.58], p-value <0.001), and reintervention (HR 14.72 [3.13-69.32], p-value <0.001). Moderate or worse PVR was associated with larger increases in left ventricular (LV) end-diastolic and systolic dimensions and volumes, LV mass indices, and reductions in LV ejection fractions (LVEFs) from 30 days to two years. Mild PVR was not associated with worse outcomes. Adjusting for LV dimensions and LVEF from the one-year echocardiogram, patients with ≥moderate PVR still had an increased risk of all-cause death or rehospitalisation at two years (HR 2.84 [1.25-5.78], p-value=0.009). CONCLUSIONS Moderate or worse PVR, but not mild PVR, is associated with an increased risk of all-cause and cardiovascular death, rehospitalisation, and reintervention at two years. Moderate or worse PVR is also associated with adverse LV remodelling, which partially mediates how ≥moderate PVR leads to worse outcomes. These results provide dual insights on the deleterious impact of ≥moderate PVR and the contributing mechanisms of poor clinical outcomes.

Abstract
Background: Smell and taste disorders are reported very frequently and at an early stage in SARS-CoV-2 infectious disease. These symptoms could be sensitive and specific to establish possible severity of the infection, and may suggest the flow of decisions as to further therapy. Objective: We asked whether smell and taste impairment are earlier and more sensitive symptoms than the RT-PCR molecular assays for SARS-CoV-2 detection. Methods: Subjects (N=275) with a probable COVID-19 diagnosis were classified as follows: Symptomatic with chemosensory dysfunction, symptomatic without chemosensory dysfunction, and asymptomatic. Validated unbiased testing of the chemosensory dysfunction was performed by means of the Venezuelan Olfactory Test and taste test. Nasal swabs and blood samples were analyzed by RT-PCR molecular analysis a rapid diagnostic test to detect the SARS-CoV-2 virus and viral antibodies, respectively. Smell and taste testing and RT-PCR were performed every 3 to 5 days to patients until full recovery. Results: Out of 144 patients that were positive for SARS-CoV-2: 45.83% had COVID-19 symptoms, smell and taste disorders; 23.61% had COVID-19 symptoms but not smell or taste disorders, and 30.55% were asymptomatic. Mild hyposmia and hypogeusia were frequently associated with SARS-CoV-2 symptoms. Recovery from chemosensory dysfunction occurred between day 3 and 14. RT-PCR becomes negative after 21 days. The Venezuelan Olfactory Test and taste test has a 61.68% positive predictive value, 45.83% sensitivity, and 68.7% specificity for SARS-CoV-2. Conclusions: Smell and taste disorders are associated symptoms with SARS-CoV-2 infection, but not a predictor of the disease, as compared to the molecular RT-PCR test.

Abstract
BACKGROUND Limited information is available regarding the risk of incident liver disease in patients with psoriasis receiving systemic therapies. OBJECTIVES To describe the liver safety findings of conventional and modern systemic therapies for moderate-to-severe psoriasis, and to compare the relative incidence rates of hepatic adverse events (AEs) for each drug. METHODS All the patients on the BIOBADADERM registry were included. Crude and adjusted incidence rate ratios (cIRR and aIRR, respectively) of hepatic AEs, using anti-TNF drugs as reference, were determined. Outcomes of interest were hypertransaminasemia, nonalcoholic fatty liver disease (NADFLD) and a group of other, less represented, hepatic AEs. RESULTS Our study included 3,171 patients exposed to systemic drugs (6279 treatment cycles). Incident hypertransaminasemia was the most frequent hepatic AE (incidence rate of 21 per 1000 patients-years [CI 95% CI 18-23]), followed by NAFLD (8 cases per 1000 patients-years [95% CI 6-10]). Methotrexate (aIRR 3.06 [2.31-4.4]; p = 0.000) and cyclosporine (aIRR 2.37 [1.05-5.35]; p = 0.0378) were associated with an increased risk for hypertransaminasemia when compared to anti-TNF-α agents. No differences were observed between different groups of biologics. Conventional therapies were not associated with new incident NAFLD. CONCLUSIONS Comparative information of the incidence of hepatic AEs could facilitate drug selection in moderate-to-severe psoriasis.

Abstract
Introduction Cyberchondria involves excessive and uncontrollable online searching of information about a perceived illness. This behavior can cause or maintain distress. Objectives Little is known about cyberchondria during the COVID-19 pandemic or how cyberchondria in one individual may cause distress in their significant other if they are self-isolating together; our study sought to fill these gaps. Methods We conducted a Qualtrics Panel survey with 760 cohabitating Canadian couples; in June 2020, participants retrospectively reported on their cyberchondria behavior, general anxiety, and COVID-19 fears during the month of April 2020, while adhering to stay-at-home advisories. Two separate actor-partner interdependence models (APIMs) used cyberchondria excessiveness and compulsion to predict generalized anxiety and COVID-19 danger/contamination fears in the actor and partner. Results Both cyberchondria excessiveness and compulsion were associated with higher general anxiety and higher COVID-19 danger/contamination fears in the individual (actor effects). Partner cyberchondria compulsion was associated with higher general anxiety in the individual whereas partner cyberchondria excessiveness was associated with higher COVID-19 danger/contamination fears in the individual (partner effects). Conclusions Findings suggest that excessive and uncontrollable searching of information about COVID-19 on the internet during lockdown may contribute to distress in both the individual engaging in the cyberchondria behavior, and in their romantic partner. Moreover, different aspects of cyberchondria in the partner (compulsion vs. excessiveness) appears to contribute to general vs. COVID-19-specific anxiety/fears in the partner, respectively. Future research should examine mechanisms underlying the observed partner effects (e.g., co-rumination, social contagion) and reasons for the differential partner effects of cyberchondria components.

Abstract
Background In May 2012 the US Preventive Task Force issued a ‘D’ recommendation against routine PSA-based early detection of prostate cancer. This recommendation was implemented progressively in our health system. The aim of this study is to define its impact on prostate cancer staging at a tertiary care institution. Methods A retrospective analysis was performed from 2012 until 2015 at a single center. We analyzed the total number of biopsies performed per year and the positive biopsy rate. For those patients with positive biopsies we recorded diagnostic PSA, clinical stage, ISUP grade group, nodal involvement and metastatic status at diagnosis. Results A total of 1686 biopsies were analyzed. The positive biopsy rate increased from 25% in 2012 to 40% in 2015 (p < 0.05). No change in median PSA was noticed (p = 0.627). The biopsies detected higher ISUP grades (p = 0.000). In addition, newly diagnosed prostate cancer presented a higher clinical stage (p = 0.005), higher metastatic rates (p = 0.03) and a tendency to higher lymph node involvement although not statistically significant (p = 0.09). Conclusion After the 2012 recommendation, patients presented a higher probability of a prostate cancer diagnosis, with a more adverse ISUP group, clinical stage and metastatic disease. These results should be taken into consideration to implement a risk adapted strategy for prostate cancer screening.

Abstract
We have clinically observed that some patients with transthyretin cardiac amyloidosis and severe aortic stenosis may have lesser degrees of calcification than one might expect. We report a case series of 3 patients with transthyretin cardiac amyloidosis and severe aortic stenosis despite discordant aortic valve calcium scores. (Level of Difficulty: Intermediate.)

Abstract
Background:
Although aortic valve replacement is associated with a major benefit in high-gradient (HG) severe aortic stenosis (AS), the results in low-gradient (LG, mean gradient <40 mm Hg) AS are conflicting. LG severe AS may be subdivided in classical low-flow (left ventricular ejection fraction <50%) and LG (CLF-LG); paradoxical low-flow (left ventricular ejection fraction ≥50% but stroke volume index <35 mL/m
2
) and LG; and normal-flow (left ventricular ejection fraction ≥50% and stroke volume index ≥35 mL/m
2
) and LG. The primary objective is to determine in the PARTNER 2 trial (The Placement of Aortic Transcatheter Valves) and registry the outcomes after aortic valve replacement of the 4 flow-gradient groups.
Methods:
A total of 3511 patients from the PARTNER 2 Cohort A randomized trial (n=1910) and SAPIEN 3 registry (n=1601) were included. The flow-gradient pattern was determined at baseline transthoracic echocardiography and classified as follows: (1) HG; (2) CLF-LG; (3) paradoxical low-flow-LG; and (4) normal-flow-LG. The primary end point for this analysis was the composite of (1) death; (2) rehospitalization for heart failure symptoms and valve prosthesis complication; or (3) stroke.
Results:
The distribution was HG, 2229 patients (63.5%); CLF-LG, 689 patients (19.6%); paradoxical low-flow-LG, 247 patients (7.0%); and normal-flow-LG, 346 patients (9.9%). The 2-year rate of primary end point was higher in CLF-LG (38.8%) versus HG: 31.8% (
P
=0.002) and normal-flow-LG: 32.1% (
P
=0.05) but was not statistically different from paradoxical low-flow-LG: 33.6% (
P
=0.18). There was no significant difference in the 2-year rates of clinical events between transcatheter aortic valve replacement versus surgical aortic valve replacement in the whole cohort and within each flow-gradient group.
Conclusions:
The LG AS pattern was highly prevalent (36.5%) in the PARTNER 2 trial and registry. CLF-LG was the most common pattern of LG AS and was associated with higher rates of death, rehospitalization, or stroke at 2 years compared with the HG group. Clinical outcomes were as good in the LG AS groups with preserved left ventricular ejection fraction compared with the HG group.

Abstract
Abstract
Objectives
To determine if diferent plant bioactive compounds can ammelirate endoplasmic reticulum stress markers in liver and adipose tissue of obese mice and mice administered with a low dose of tunicamicin.
Methods
C57BL6 mice were fed a control diet (7% fat) or a high-fat diet (21% fat) with and without genistein or resveratrol supplementation (0.1%) for 12 weeks. Pharmacologic ER stress was induced in mice fed the control diet by an ip injection of a low dose of tunicamycin and euthanized 8 or 24 h after tunicamycin administration. Adipose tissues and liver were harvested to determine the abundance of ER stress markers by western blot and real time PCR.
Results
Genistein and resveratrol reduced the abundance of phospho JNK and phospho PERK in liver and subcutaneous adipose tissue of obese mice and lean mice administered with tunicamycin. Both polyphenols increased the mRNA abundance of XBP1s and BiP and reduced that of CHOP in both organs. These changes in proten phosphorylation and gene expression were accompanied with reduced hepatic steatosis and adipocyte hypertrophy.
Conclusions
The supplementation with plant polyphenols such as genistein or resveratrol reduced ER stress markers in liver and adipose tissue of obese mice and lean mice administerd with tunicamycin.

Abstract
BACKGROUND: The parathyroid adenoma producing an excess of PTH is characterized by hypercalcemia, asthenia, physical weakness and renal lithiasis. This clinical case is presented only with a dry (non-productive) cough sign of long duration.CASE: 51-year-old female born in Padre Las Casas, D.R. presenting with chief complain of dry cough for about four years.

Abstract
As the number of people living with undiagnosed HIV infection in the UK declines, innovative ways to access those least engaged with services are needed. This study explores the attitudes of men who have sex with men (MSM) towards using HIV self-testing (HIVST) kits distributed via a vending machine in a sauna (a licenced sex-on-premise venue). Twenty-three MSM attending the sauna were recruited to take part in semi-structured qualitative interviews. The participants were overwhelmingly positive about the HIVST vending machine. They identified convenience and flexibility as major benefits to testing in this way. The sauna was felt to be an appropriate location for the intervention. Limitations identified included the potential to reduce screening for other sexually transmitted infections and the inappropriate use of HIVST kits as a tool for risk-assessment prior to condomless sex, with a poor understanding of the window period. The implications of receiving a positive result without immediate access to support were also a concern. HIVST vending machines are an acceptable, innovative way to encourage HIV testing. Providers need to ensure this intervention is supported by adequate information regarding the limitations of the test and how to access comprehensive services to avoid any unintended negative effects.

Abstract
Prostaglandin E2 (PGE2) is an important mediator of cellular responses, playing a key role in limiting inflammation. PGE2 acts distinctly through one of four EP receptors. In MSCs, it PGE2 stimulation of EP2 and EP4 receptors triggers processes such as migration, self-renewal, survival, and proliferation, and their activation is involved in homing. PGE2 has been proposed as a key factor of MSC immunomodulation. The CRISPR-Cas9 system has been adapted successfully to edit the genome of animals. Loss of EP2 and EP4 receptors in equine adipose mesenchymal stem cells (eAT-MSC) could help us understand their role in cell migration, homing, and self-renewal capacities. Here, we aimed to edit these receptors in eAT-MSC to test their function. The eAT-MSC were obtained from three Chilean breed horses and cultured in Dulbecco's modified Eagle's medium-high glucose with 10% fetal bovine serum. Guide RNAs (sgRNA) for CRISPR-Cas 9 editing were designed based on EP2 and EP4 DNA sequences. The sgRNA and PAM sequence targeting exon 1 of the equine genes (EP2-sgRNA: TGGTGCTGGCTTCGTACGCG; PAM:CGG and EP4-sgRNA: GGAGACGACCTTCTACACGT;PAM:TGG) were cloned into linearized LentiCRISPRv2GFP vector (#82416; Addgene). The lentiviral vector plus helping packaging plasmids was co-transfected into HEK293FT cells. The produced viral particles were harvested and transduced into eAT-MSC. After 48h, cells were sorted and green fluorescent protein (GFP)-positive cells were expanded to obtain individual clones. Genomic DNA was extracted for PCR amplification, and the frequency of site directed-mutation was assessed by T7 endonuclease assay. Because of the high background (e.g. excessive banding) produced by the T7E1 assay, the PCR products were cloned into a pUC57 vector, and sequenced. Quantitative PCR and immunocytochemistry staining examined expression of EP2 and EP4. The statistical analyses were performed using GraphPad Prism 6 (GraphPad Inc.) with unpaired t-test; P-values<0.05 were considered statistically significant. Transduction efficiency of eAT-MSC/EP2ko and eAT-MSC/EP4ko was 31 and 38%, respectively. A total of 15 clones for each lineage obtained from a single cell culture were subjected to T7EI assay to identify the frequency of mutation. Eight eAT-MSC/EP2ko and 7 eAT-MSC/EP4ko clones showed mutations; DNA sequencing confirmed mutations in 3 eAT-MSC/EP2ko clones and 3 eAT-MSC/EP4ko clones. Immunostaining with specific anti-EP2 and anti-EP4 antibodies showed diminished expression of the particular receptors in the knockout cells. Decreased expression was quantitatively confirmed by quantitative PCR analysis, showing downregulation of PTGER2 (4.3-fold) and PTGER4 (2.7-fold) in the edited clones compared with eAT-MSC naïve cells (P<0.05). This CRISPR/Cas9 design allows the possibility of using these mutant cell lines as a model system to elucidate the role of EP2 and EP4 in cell migration, homing, and self-renewal.

Abstract
Insulin resistance is a core pathophysiological defect underscoring type 2 diabetes mellitus (T2DM) and non-alcoholic fatty liver disease (NAFLD). Both conditions improve with duodenal exclusion surgery. Duodenal mucosal resurfacing (DMR) is an endoscopic intervention developed to treat metabolic disease which has been shown to improve glycaemia in patients with poorly controlled T2DM. Herein, we aimed to further analyse the effects of DMR on hepatic and metabolic parameters in this patient cohort. Methods Eighty-five patients with T2DM who received endoscopic DMR treatment were enrolled from 5 centres and followed up for 6 months. We assessed safety in all patients. Efficacy was evaluated in patients who received at least 9 cm of duodenal ablation (n = 67). Endpoints included HbA1c, fasting plasma glucose, weight and aminotransferase levels. Metabolomic analysis was conducted in a subgroup (n = 14). Data were analysed using paired t test or ANOVA for repeated measures with Bonferroni correction and correction for initial weight loss if applicable. Results The DMR procedure was completed with no intraprocedural complications in the entire cohort. HbA1c was lower 6 months after DMR than at baseline (7.9 ± 0.2% vs. 9.0 ± 0.2% [mean ± SE], p ≪0.001). Fasting plasma glucose was also significantly lower 6 months after DMR compared to baseline (161 ± 7 mg/dl vs. 189 ± 6 mg/dl, p = 0.005). Body weight decreased slightly. At 6 months, alanine aminotransferase had decreased from 41 ± 3 IU/L to 29 ± 2 IU/L (p ≪0.001) and aspartate aminotransferase had decreased from 30 ± 2 IU/L to 23 ± 1 IU/L (p ≪0.001). Metabolomic analysis demonstrated that DMR had key lipid-lowering, insulin-sensitizing and anti-inflammatory effects, as well as increasing antioxidant capacity. Mean FIB-4 was also markedly decreased. Conclusion Hydrothermal ablation of the duodenum by DMR elicits a beneficial metabolic response in patients with T2DM. DMR also improves hepatic indices, potentially through an insulin-sensitizing mechanism. These encouraging data deserve further evaluation in randomized controlled trials. Lay summary Hydrothermal duodenal mucosal resurfacing (DMR) is an endoscopic technique designed to treat metabolic disease through ablation of the duodenal mucosa. DMR is a safe procedure which improves glycaemia and hepatic indices in patients with type 2 diabetes mellitus. DMR is an insulin-sensitizing intervention which can be complementary to lifestyle intervention approaches and pharmacological treatments aimed at preserving the pancreas and liver from failure. DMR is a potential therapeutic solution for patients with type 2 diabetes and fatty liver disease.

Abstract
Abstract
Background
There is scarce evidence about the prevalence and clinical relevance of moderate to severe valvular heart disease (VHD) in survivors of out of hospital cardiac arrest (OHCA).
Purpose
To determine whether VHD influence prognosis of OHCA survivors.
Methods
All consecutive patients admitted to the Acute Cardiac Care Unit after OHCA and surviving until hospital discharge were included. All patients received targeted-temperature management according to our local protocol. Univariate and multivariate Cox-proportional hazard models were employed.
Results
A total of 201 patients were included in the analysis. Mean age was 57.6±14.2 years and 168 (83.6%) were male. Eighteen patients (9.0%) had moderate or severe VHD during index admission (Table 1). Patients with VHD were less frequently of male sex, [11 (61.1%) vs 157 (85.8%), p=0.014], experienced less acute coronary syndrome-related arrhytmias [2 (11.1%) vs 85 (46.5%), p=0.005], and had a lower pH at hospital admission (6.9±1.6 vs 7.2±0.15, p=0.008). During a median follow-up of 40.3 (18.9–69.1) months, patients with VHD showed higher mortality [7 (38.9%) vs 28 (15.3%), p=0.004] and more heart failure-related admissions [7 (38.9%) vs 15 (8.2%), p<0.001]. Only five patients received surgical or percutaneous treatment for VHD during follow-up, with no deaths in this subgroup. Moderate or severe VHD proved to be an independent predictor of global cardiovascular events and specifically heart failure episodes (Figure 1).

Conclusion
The presence of significant VHD in survivors after OHCA is a predictor of poor outcomes. Specific management of VHD may be specially relevant in this high-risk patients and guideline-oriented therapy, including surgery and percutaneous intervention should be encouraged when indicated.

Abstract
Abstract
Background
Platelet/lymphocyte ratio (PLR), an inflammatory marker associated with poor outcomes in different clinical situations, may play a role in the proinflammatory state triggered during hypoxic-ischemic brain injury secondary to cardiac arrest.
Purpose
To study PLR dynamics and its relationship with neurologic outcomes in survivors after CA treated with target-temperature-management (TTM).
Methods
Observational retrospective study from a prospective database of survivors of in-hospital and out-of-hospital CA admitted to our Acute Cardiac Care Unit between August 2006 to December 2018. All patients received TTM according to our local protocol.
Results
A total of 466 patients were included. Mean age was 62.7±14.4 years and 102 (21.9%) were women. Baseline characteristics are shown in Table 1. 430 (92.2%) of CA were witnessed, 312 (67.0%) had ventricular fibrillation as initial cardiac rhythm. Among them, 236 (51.1%) survived until hospital discharge and 208 (45.1%) presented favorable neurological outcomes (a score 1 or 2 on cerebral performance category (CPC)). The mean value of PLR at admission and during targeted temperature was 100.4±5.2 and 224.5±7.3 respectively (mean difference 123.1±7.1, p<0.0001). This increase in PLR was significantly higher among patients with worse neurological outcomes (CPC 3–5, mean DPLR 138.2±5.5) at 3 months compared with survivors with CPC 1–2 (mean DPLR 108.2±6.3, p=0.0348 for paired comparison between both groups).
Table 1 Hypertension, n (%) 235 (54.9) Diabetes, n (%) 113 (26.4) Dyslipidaemia, n (%) 171 (40.0) Smocking habit, n (%) 208 (48.5) Time to ROSC mean ± SD, min 26.6±18.6 Mean arterial pressure at HA mean±DS, mmHg 81.3±22.1 pH at HA mean ± SD 7.18±0.16 Lactic at HA mean ± SD 6.37±4.42 ROSC: return of spontaneus circulation; HA: hospital admission.
Conclusion
Our findings reflect the impact of inflammation in neurological outcomes after OHCA treated with TTM. Major increases of PLR constitute a novel marker of poor prognosis during early assessment of OHCA patients.

Abstract
BACKGROUND AND AIMS We aimed to develop duodenal mucosal resurfacing (DMR), a minimally invasive upper endoscopic hydrothermal ablation procedure, to treat insulin-resistant metabolic diseases. METHODS We completed a sham-controlled, rodent proof-of-concept study and longitudinal safety study in pigs to demonstrate feasibility to test DMR in humans. Subsequently, the DMR procedure was implemented in an open-label first-in-human (FIH) study of safety and efficacy in patients with type 2 diabetes (T2D). RESULTS In rats, duodenal abrasion reduced hyperglycemia by 59 mg/dL on average, compared with no change from baseline in the sham treatment arm (P < .05). In pigs, the balloon catheter successfully and safely delivered hydrothermal ablation to the duodenal mucosa and superficial submucosa. Complete mucosal healing was demonstrated by week 6. In the FIH study, hydrothermal ablation was successfully administered with no evidence of perforation, pancreatitis, or hemorrhage. Duodenal biopsy specimens obtained 3 months postprocedure demonstrated full mucosal regrowth. No inflammation was observed, and there was minimal-to-mild collagen banding deposition observed in a proportion of ablation site biopsy specimens with no evidence of fibrotic scarring. Glycemic and hepatic measures improved through 6 months of follow-up. CONCLUSIONS DMR shows potential as an endoscopic intervention that improves glycemic and hepatic parameters in patients with T2D. Further mechanistic and clinical studies are underway to further explore DMR as a treatment for metabolic disease.

Abstract
ObjectivesA substantial number of patients with severe tricuspid regurgitation (TR) and congestive heart failure (CHF) are medically managed without undergoing corrective surgery. We sought to assess the characteristics and outcomes of CHF patients who underwent tricuspid valve surgery (TVS), compared with those who did not.MethodsRetrospective observational study involving 2556 consecutive patients with severe TR from the Cleveland Clinic Echocardiographic Database. Cardiac transplant patients or those without CHF were excluded. Survival difference between patients who were medically managed versus those who underwent TVS was compared using Kaplan-Meier survival curves. Multivariate analysis was performed to identify variables associated with poor outcomes.ResultsAmong a total of 534 patients with severe TR and CHF, only 55 (10.3%) patients underwent TVS. Among the non-surgical patients (n=479), 30% (n=143) had an identifiable indication for TVS. At 38 months, patients who underwent TVS had better survival than those who were medically managed (62% vs 35%; p<0.001). On multivariate analysis, advancing age (HR: 1.23; 95% CI 1.12 to 1.35 per 10-year increase in age), moderate (HR: 1.39; 95% CI 1.01 to 1.90) and severe (HR: 2; 95% CI 1.40 to 2.80) right ventricular dysfunction were associated with higher mortality. TVS was associated with lower mortality (HR: 0.44; 95% CI 0.27 to 0.71).ConclusionAlthough corrective TVS is associated with better outcomes in patients with severe TR and CHF, a substantial number of them continue to be medically managed. However, since the reasons for patients not being referred to surgery could not be ascertained, further randomised studies are needed to validate our findings before clinicians can consider surgical referral for these patients.

Abstract
BACKGROUND Identifying biomarkers for cells harboring replication-competent HIV is a major research priority. Recently, there have been mixed reports addressing the possibility that CD32-expressing T cells are enriched for HIV. There is growing evidence that CD32 expression increases with cellular activation that may be related to, but not necessarily specific for, infection with HIV. However, the relationship of CD32 expression to HIV-infection in subtypes of tissue-resident leukocytes is unclear. METHODS First, we used duplex chromogenic in situ hybridization to identify cells actively transcribing RNA for both CD32 and HIV on human gut tissues. Then we performed multiplexed immunofluorescence and in situ hybridization (mIFISH) on sections from the same tissues to determine the phenotype of individual cells co-expressing HIV-RNA and CD32-RNA. RESULTS HIV-RNA+ cells were more abundant in tissues from viremic individuals than in those receiving suppressive anti-retroviral therapy (ART). However, staining by both methods indicated that a higher proportion of HIV-RNA+ cells co-expressed CD32-RNA in ART-suppressed individuals than in those with viremia. The majority of HIV-RNA+ cells were CD3+. CONCLUSIONS Our data suggest that the transcription of CD32-RNA is correlated with HIV transcriptional activity in CD3+ cells found within human gut tissue. Whether or not up-regulation of CD32-RNA is a direct result of HIV transcription or more global T-cell activation remains unclear.
