Abstract
Endothelial dysfunction is an early event in coronary microvascular disease. Integrin-linked kinase (ILK) prevents endothelial nitric oxide synthase (eNOS) uncoupling and, thus, endothelial dysfunction. However, the specific role of endothelial ILK in cardiac function remains to be fully elucidated. We hypothesised that endothelial ILK plays a crucial role in maintaining coronary microvascular function and contractile performance in the heart. We generated an endothelial cell-specific ILK conditional knock-out mouse (ecILK cKO) and investigated cardiovascular function. Coronary endothelial ILK deletion significantly impaired cardiac function: ejection fraction, fractional shortening and cardiac output decreased, whilst left ventricle diastolic internal diameter decreased and E/A and E/E' ratios increased, indicating not only systolic but also diastolic dysfunction. The functional data correlated with extensive extracellular matrix remodelling and perivascular fibrosis, indicative of adverse cardiac remodelling. Mice with endothelial ILK deletion suffered early ischaemic-like events with ST elevation and transient increases in cardiac troponins, which correlated with fibrotic remodelling. In addition, ecILK cKO mice exhibited many features of coronary microvascular disease: reduced cardiac perfusion, impaired coronary flow reserve and arterial remodelling with patent epicardial coronary arteries. Moreover, endothelial ILK deletion induced a moderate increase in blood pressure, but the antihypertensive drug Losartan did not affect microvascular remodelling whilst only partially ameliorated fibrotic remodelling. The plasma miRNA profile reveals endothelial-to-mesenchymal transition (endMT) as an upregulated pathway in endothelial ILK conditional KO mice. Our results show that endothelial cells in the microvasculature in endothelial ILK conditional KO mice underwent endMT. Moreover, endothelial cells isolated from these mice and ILK-silenced human microvascular endothelial cells underwent endMT, indicating that decreased endothelial ILK contributes directly to this endothelial phenotype shift. Our results identify ILK as a crucial regulator of microvascular endothelial homeostasis. Endothelial ILK prevents microvascular dysfunction and cardiac remodelling, contributing to the maintenance of the endothelial cell phenotype.

Abstract
This study aimed to clarify the relations between morphological awareness and literacy skills in Spanish and English in young simultaneous bilingual learners. Guided by theoretical perspectives on the associations between morphological awareness and word- versus sentence-level literacy skills, and their transfer between bilinguals' two languages, we asked bilingual children (N = 90; M = 8.07 years old) to complete dual-language literacy assessments. First, we observed cross-linguistic differences in the associations between morphology and reading. In English, morphological awareness was directly related to word reading and reading comprehension, whereas in Spanish, the association with reading comprehension was fully mediated by vocabulary and single word reading. Second, we observed cross-linguistic associations from English word reading to Spanish reading comprehension, and from Spanish reading comprehension to English reading comprehension. Our findings inform bilingual literacy theory by revealing both cross-linguistic differences and bidirectional associations between literacy skills across typologically-distinct orthographies. In particular, children's word-level skills transferred from the language of schooling (English) into their heritage language (Spanish), and their broader reading comprehension skills transferred from the heritage language to support English. Taken together, these findings support the value of bilingual heritage language maintenance for reading achievement in children's dominant language of literacy instruction.

Abstract
Introduction HIV is considered one of the most important chronic transmitted diseases worldwide. The Joint United Nations Program on HIV/AIDS in 2020 proposed the strategy “95–95–95” which goals to achieve a 95% of cases identified, receives ART, and will have achieved suppression of the virus. In Ecuador by 2020, according to the Ministry of Public Health, 45,056 persons are living with HIV, principally men between 15 and 49 years, and a mortality rate of 4.8/100,000 habitats. This study aims to determine the cost–utility of applying an early screening to a sexually active population vs. only a high-risk population and if the use of PrEP is justified depending on different contexts. Methods For the cost–utility evaluation, it was compared: (a) HIV screening performed only in the high-risk population vs. HIV screening in all population sexually active; and (b) the use of ART only for HIV treatment vs. ART as a treatment in diagnosed cases and the use of PrEP (only at a high-risk population of acquiring HIV). Calculation and weight of DALYs for HIV/SIDA were obtained through WHO guidelines. To generate the Markov model for HIV/AIDS, subjects were classified as symptomatic or asymptomatic, as well as the HIV deaths. Results Cost–benefit analysis (CUA) showed that ICER for early diagnosis had a negative value which means a saving if the strategy will be implemented as a regular test (–$591, –$4,360) and −108 and −934 DALYs, in the case of ART and PrEP, ICER the $30,541–$59,410, which resulted in more than the GDP's threshold and health years between 2,511 and 10,635 in the general population. With a reduction of 70% in the assigned budget for the early diagnosis, Ecuadorian people could lose between 4 and 6 DALYs, while if the budget reduces more than 50% to ART, it will generate a loss of 10–12 years of healthy life. Conclusion CUA demonstrates that an early diagnosis in a sexually active population is cost-beneficial. This, combined with ART or PrEP, is ideal to add years of healthy life.

Abstract
The current feline genotyping array of 63 k single nucleotide polymorphisms has proven its utility for mapping within breeds, and its use has led to the identification of variants associated with Mendelian traits in purebred cats. However, compared to single gene disorders, association studies of complex diseases, especially with the inclusion of random bred cats with relatively low linkage disequilibrium, require a denser genotyping array and an increased sample size to provide statistically significant associations. Here, we undertook a multi-breed study of 1,122 cats, most of which were admitted and phenotyped for nine common complex feline diseases at the Cornell University Hospital for Animals. Using a proprietary 340 k single nucleotide polymorphism mapping array, we identified significant genome-wide associations with hyperthyroidism, diabetes mellitus, and eosinophilic keratoconjunctivitis. These results provide genomic locations for variant discovery and candidate gene screening for these important complex feline diseases, which are relevant not only to feline health, but also to the development of disease models for comparative studies.

Abstract
In this study, changes in air quality by NO2, O3, and PM10 in Barcelona metropolitan area and other parts of Catalonia during the COVID-19 lockdown with respect to pre-lockdown and to previous years (2018 and 2019) were evaluated. Selected air monitoring stations included 3 urban (Gràcia, Vall d'Hebron, and Granollers), 1 control site (Fabra Observatory), 1 semi-urban (Manlleu), and 3 rural (Begur, Bellver de Cerdanya, and Juneda). NO2 lockdown levels showed a diminution, which in relative terms was maximum in two rural stations (Bellver de Cerdanya, - 63% and Begur, - 61%), presumably due to lower emissions from the ceasing hotel and ski resort activities during eastern holidays. In absolute terms and from an epidemiologic perspective, decrease in NO2, also reinforced by the high amount of rainfall registered in April 2020, was more relevant in the urban stations around Barcelona. O3 levels increased in the transited urban stations (Gràcia, + 42%, and Granollers, + 64%) due to the lower titration effect by NOx. PM10 lockdown levels decreased, mostly in Gràcia, Vall d'Hebron, and Granollers (- 35, - 39%, and - 39%, respectively) due to traffic depletion (- 90% in Barcelona's transport). Correlation among mobility index in Barcelona (- 100% in retail and recreation) and contamination was positive for NO2 and PM10 and negative for O3 (P < 0.001). Satellite images evidenced two hotspots of NO2 in Spain (Madrid and Barcelona) in April 2018 and 2019 that disappeared in 2020. Overall, the benefits of lockdown on air quality in Catalonia were evidenced with NO2, O3 and PM10 levels below WHOAQG values in most of stations opposed to the excess registered in previous years.

Abstract
BACKGROUND We assessed nasopharyngeal pneumococcal carriage in Andean Kichwa children, the largest Amerindian indigenous population in the Ecuadorian Andes. All children in our study had been vaccinated with the 10-valent pneumococcal vaccine (PCV10). METHODS Nasopharyngeal swabs from 63 families, 100 children <10 years old including 38 children under 5 years and 63 adult caregivers, from 5 different communities, were cultivated for Streptococcus pneumoniae and isolates were serotyped and antibiotic susceptibility testing was performed. RESULTS Respectively, 67% of the 38 children under 5 years old, 49% of the 62 children between 6 and 10 years old and 16% of the 100 adults were colonized with S. pneumoniae. Of these, 30.9% carried a vaccine serotype, 5.4% a serotype shared by the PCV10/13-valent pneumococcal vaccine (PCV13) vaccine and 25.5% a PCV13 serotype or PCV13 vaccine-related serotype, with 19A (10.9%) and 6C (10.9%) as the most prominent. Drug susceptibility testing revealed that 46% of the S. pneumoniae strains were susceptible to 6 tested antibiotics. However, 20.3% of the strains were multidrug-resistant or extensively drug-resistant strains, including 82% of the vaccine (-related) serotype 19A and 6C strains. CONCLUSIONS Kichwa children, vaccinated with PCV10, were highly colonized with pneumococci and should be considered a high-risk group for pneumococcal disease. Twenty-five percent of the colonizing S. pneumoniae strains were PCV13-only vaccine-targeted serotypes, and in addition to that, most were multidrug-resistant or extensively drug-resistant strains. The vaccine benefits for this population possibly will significantly increase with the introduction of PCV13.

Abstract
Psychotic symptoms, defined as the occurrence of delusions or hallucinations, are frequent in Alzheimer disease (AD with psychosis, AD + P). AD + P affects ~50% of individuals with AD, identifies a subgroup with poor outcomes, and is associated with a greater degree of cognitive impairment and depressive symptoms, compared to subjects without psychosis (AD - P). Although the estimated heritability of AD + P is 61%, genetic sources of risk are unknown. We report a genome-wide meta-analysis of 12,317 AD subjects, 5445 AD + P. Results showed common genetic variation accounted for a significant portion of heritability. Two loci, one in ENPP6 (rs9994623, O.R. (95%CI) 1.16 (1.10, 1.22), p = 1.26 × 10-8) and one spanning the 3'-UTR of an alternatively spliced transcript of SUMF1 (rs201109606, O.R. 0.65 (0.56-0.76), p = 3.24 × 10-8), had genome-wide significant associations with AD + P. Gene-based analysis identified a significant association with APOE, due to the APOE risk haplotype ε4. AD + P demonstrated negative genetic correlations with cognitive and educational attainment and positive genetic correlation with depressive symptoms. We previously observed a negative genetic correlation with schizophrenia; instead, we now found a stronger negative correlation with the related phenotype of bipolar disorder. Analysis of polygenic risk scores supported this genetic correlation and documented a positive genetic correlation with risk variation for AD, beyond the effect of ε4. We also document a small set of SNPs likely to affect risk for AD + P and AD or schizophrenia. These findings provide the first unbiased identification of the association of psychosis in AD with common genetic variation and provide insights into its genetic architecture.

Abstract
Abstract
Study question
Is it possible to automate the way sperm is injected in an oocyte and improve ICSI consistency between embryologists?
Summary answer
The developed ICSI robot demonstrated a high degree of consistency and operator skill independence, allowing human supervision and external control, but minimal manual intervention.
What is known already
ICSI is a clinical procedure that is currently performed worldwide in most IVF centers and its use will only increase with more utilization of egg freezing. Since its implementation, the technique has been conducted manually by highly skilled embryologists. However, success rates can vary significantly depending on the experience of the operator. We leverage our experience in robotics, AI algorithms and embryology to develop an automated ICSI robot that requires minimal manual intervention with the aim to standardize the consistency of the procedure and, ultimately, improve overall results maintaining embryologist oversight.
Study design, size, duration
The ICSI robot was developed to have supervised automated control on critical steps of the injection procedure, including injection pipette advancement, zona pellucida and oolemma penetration with piezo-pulses, and pipette removal after injection. Manual intervention is required only for immobilization and capture of spermatozoa with a joystick gamepad and to release the sperm in the ooplasm, without the need for micromanipulation skills. In parallel, piezo-ICSI was performed in a conventional micromanipulation station as a control.
Participants/materials, setting, methods
Hamster and mouse oocytes were collected from superovulated females. For testing the efficiency of the automated system, hamster oocytes were injected with human donor sperm, as historically used in manual ICSI training programs, and survival rates evaluated after overnight culture. Mouse oocytes were injected with mouse sperm heads and subsequently cultured in vitro for five days. Blastocysts obtained were vitrified and embryo transfers are ongoing to evaluate term developmental rates.
Main results and the role of chance
The technical components of the ICSI robot were engineered to integrate AI algorithms, optics, cell microinjectors and mechatronics. AI algorithms were developed to identify the morphological structures of MII oocytes, including the zona pellucida, perivitelline space and polar body, both in the hamster and mouse models. The system detects and analyzes both the pipette and the oocyte and chooses the best area and plane for injection, allowing automated control of the subsequent injection steps. Using the hamster oocyte-human sperm model, a survival rate of 91% (n = 110) was achieved with the robot, which was statistically similar (p = 0.335) to the results obtained in the controls injected manually (96%, n = 28). The average time spent in each injection cycle, which includes scanning of the oocyte and injection pipette, and injection of the sperm into the oocyte, was approximately two minutes per ICSI operation. This time was comparable to the time required by highly experienced operators with manual piezo-injection. In the mouse, 91% (n = 53) of the oocytes injected survived the procedure, of which, 92% developed to two-cells and 87% to the blastocyst stage. No statistical differences were found when compared these efficiencies with manual controls (n = 40, 98%, 97% and 92%, respectively).
Limitations, reasons for caution
The developed ICSI robot has shown highly consistent results, independently of operator skills, both in hamster and mouse oocytes. However, additional validations should be performed to enlarge the sample size of injected oocytes and to evaluate the efficiency of the system in other oocyte species, including translational studies to humans.
Wider implications of the findings
The combination of multidisciplinary teams allows the development of automated processes that can reduce variability in certain IVF procedures, while supervised and assisted by experienced embryologists. It is expected that other laboratory procedures can be automated in the field of assisted reproductive treatments in a near future.

Abstract
BACKGROUND Prescription affordability is a key component of healthcare accessibility and a determinant of health outcomes. Prior studies indicate that up to 1 in 4 Americans report difficulty affording prescriptions. OBJECTIVE(S) This study aims to identify factors associated with cost-based prescription refusal. METHODS We identified 17,869 study participants from the 2017 National Health Interview Survey who had been prescribed at least one medication in the past 12 months. The outcome was defined as inability to afford at least one prescription medication. Covariates included demographic data, medical history, and social attitudes. Logistic regression models were constructed to identify predictors of cost-based prescription refusal. RESULTS Among 8223 study participants, 8.1% reported the inability to afford at least one prescription medication in the past 12 months. Twenty-seven covariates were correlated with prescription unaffordability, and 8 were selected by the LASSO: Income (Odds ratio (OR) 0.55), Concerned About Bills (OR 2.0), Emergency Department Visits past 12 months (OR 1.33), Dissatisfaction with Medical Care (OR 1.3), Seeking Insurance Through the Health Insurance Marketplace (OR 1.26), Feeling Sad Most of the Time (OR 1.24), History of Asthma (OR 1.26) and History of Diabetes (OR 1.24). CONCLUSIONS Prescription unaffordability remains a significant public health problem and is more common among low-income individuals and patients with, chronic medical conditions.

Abstract
Background:Spain has been one of the countries most impacted by the COVID-19 pandemic. Among Spanish patients, 56,799 deaths have been reported. Although we have been in this situation of pandemic for a year, studies that show risk mortality rates in patients with rheumatic diseases continue to be scarce.Objectives:In patients with rheumatic and musculoskeletal diseases (RMDs) and infected with Covid – 19, a) we want to assess the mortality rate (MR) related to COVID-19; and b) to analyze the role of RMDs in mortality risk.Methods:An observational longitudinal study was conducted during the epidemic peak in Madrid (1stMar to 20thMay2020). All patients attended at the rheumatology outpatient clinic of a tertiary hospital with a diagnosis of RMDs and SARS - CoV 2 infection were included (according to a medical diagnosis or confirmed with a positive SARS-CoV-2 PCR diagnostic test). All patients were included since the time of COVID-19 diagnosis. Main outcome: death related to COVID-19 infection. Independent variable: type of RMDs including: autoimmune (systemic autoimmune conditions (SAC) and inflammatory joint disease (IJD)) and non–autoimmune (mechanical diseases and inflammatory diseases (microcrystalline arthritis and tendonitis)). Covariates: sociodemographic, comorbidities, chronic use of corticoids prior to COVID-19 infection. Survival techniques were used to estimate the MR related to COVID-19, given per 1,000 persons-month with a 95% confidence interval [CI]. The time of observation comprised the elapsed time between the date of COVID-19 diagnosis of infection until the date of patient’s death, or end of study. Cox multiple regression analysis was run to examine the effect of autoimmune RMDs compared to non-autoimmune RMDs on mortality risk adjusted by sex, age and comorbidities. Results were expressed by Hazard Ratio (HR) and [CI].Results:406 patients were included with RMD and Covid – 19 infection with a total follow-up 642.5 patients-month. 69.21% were women with a mean age at diagnosis of 60 ± 15.26 years. The evolution time from the diagnosis of rheumatic disease was 8 ± 8.38 years. 26% had comorbidity at baseline. 25% were chronically on corticoids prior to the infection. Of the 406 patients, 244 (60.09%) had non-autoimmune RMD (157 mechanic, 87 inflammatory) and 162 (39.9%) (106 (65.43%) IJD, 56 (34.56%) systemic condition) had autoimmune RMD. Of the 406 patients, 45 (11%) died during the follow-up, being 12± 14 days the mean time from infection to death (P50: 6[2-12] and a maximum of 60 days). MR was estimated in 70.03 [52.28-93.79] per 1,000 persons-month. MR was higher for men (MR 105[68-163]) than for women (MR 55 [37.2-81.6]) and in older people (MR <60: 4.4, [0.6-31.7]; MR 60-75 years: 38.7[17.3-86.2]; MR >75Years: 486 [354-1668]). The HR of mortality in autoimmune RMDs compared to non-autoimmune RMDs did not achieved statistical significance (HR: 1.39 [0.77-2.5], p=0.27). After adjusting for confounders, we did not find higher risk of mortality among the different types of RMDs (HR autoimmune vs non-autoinmunes: HR: 1.12 [0.6-2.02], p=0.7; HR IJD vs SAC; 1.5 [0.6-3.6], p=0.34; HR non-autoimmune vs SAC: 1.1 [0.5-2.5], P=0.7). Age (HR: 1.12; [1.10-1.15], p<0.001), and the presence of comorbidities (HR: 2.05; [1.08-3.89], p=0.027) increased the Mortality risk.Conclusion:In patients with RMD and COVID-19 infection, we found a mortality rate of 7 per 100 persons-month. This study shows that the mortality risk related to COVID-19 is similar between autoimmune and non-autoimmune diseases after adjusting by confounders. We also found that age and comorbidities are risk factors for mortality related to COVID-19 infection.References:[1]Jorge A, et al.

Abstract
We present the clinical and neuropathological findings of a patient with early onset Alzheimer's dementia (AD), heterozygous carrier of the rare Apolipoprotein E Christchurch (APOEch) variant. The patient did not harbor any pathogenic mutation in known Mendelian genes related to AD or other neurodegenerative disorders. A sibling of this patient, also carrying the APOEch variant, developed AD at the age of 66 years old. Our data suggest a possible deleterious effect of this variant, which contrast with the protective role that has been previously shown in a subject homozygous for the APOEch with he Paisa PSEN1 mutation.

Abstract
Background It is well known that people living with HIV (PLWH) is in higher risk for the development of depression and it has also been suggested that the use of efavirenz into the antiretroviral regimens increases even that risk. Objective To evaluate the effect of efavirenz-containing antiretroviral regimens on the development of depression in newly ART initiated HIV patients in Ecuador. Methods In a prospective cohort study from June 2016 to May 2017, all newly HIV diagnosed patients at the HIV/AIDS Unit of the Hospital Eugenio Espejo in Quito, Ecuador were evaluated using the Hamilton Rating Scale for Depression followed by a second assessment 8–12 weeks after antiretroviral therapy containing efavirenz was initiated. Results A total of 79 patients, mainly males younger than 35 years were studied. Majority of them were on TDF/FTC/EFV. Initial score in Hamilton Rating Scale revealed that less than 30% had no depression symptoms while almost 40% had mild depression. However, in the second assessment, 22.6% of the subjects had a score in the Hamilton Rating Scale compatible with severe or very severe depression (RR 1.58, 95% CI 1.09 to 2.28; p = 0.05). Conclusion In our cohort study, depression was much higher in patients on Efavirenz-containing treatments. Therefore, assessment for depression must be essential as part of follow-up in these patients.

Abstract
Kinesin-2 enables ciliary assembly and maintenance as an anterograde intraflagellar transport (IFT) motor. Molecular motor activity is driven by a heterotrimeric complex comprised of KIF3A and KIF3B or KIF3C plus one non-motor subunit, KIFAP3. Using exome sequencing, we identified heterozygous KIF3B variants in two unrelated families with hallmark ciliopathy phenotypes. In the first family, the proband presents with hepatic fibrosis, retinitis pigmentosa, and postaxial polydactyly; he harbors a de novo c.748G>C (p.Glu250Gln) variant affecting the kinesin motor domain encoded by KIF3B. The second family is a six-generation pedigree affected predominantly by retinitis pigmentosa. Affected individuals carry a heterozygous c.1568T>C (p.Leu523Pro) KIF3B variant segregating in an autosomal-dominant pattern. We observed a significant increase in primary cilia length in vitro in the context of either of the two mutations while variant KIF3B proteins retained stability indistinguishable from wild type. Furthermore, we tested the effects of KIF3B mutant mRNA expression in the developing zebrafish retina. In the presence of either missense variant, rhodopsin was sequestered to the photoreceptor rod inner segment layer with a concomitant increase in photoreceptor cilia length. Notably, impaired rhodopsin trafficking is also characteristic of recessive KIF3B models as exemplified by an early-onset, autosomal-recessive, progressive retinal degeneration in Bengal cats; we identified a c.1000G>A (p.Ala334Thr) KIF3B variant by genome-wide association study and whole-genome sequencing. Together, our genetic, cell-based, and in vivo modeling data delineate an autosomal-dominant syndromic retinal ciliopathy in humans and suggest that multiple KIF3B pathomechanisms can impair kinesin-driven ciliary transport in the photoreceptor.

Abstract
Background:Uveitis are characterized by inflammation of the middle layer of the eye wall. In developed countries uveitis are the second major treatable cause of blindness in those 20–65 years of age. Additionally, more than 50% of the subjects affected with these conditions will develop complications related to the uveitis, and more than 30% will suffer visual impairment. As a result, these conditions are associated with an important burden. The assessment of the patient’s quality of life (QoL) through standardized and validated questionnaires allows us to evaluate objectively the burden of the disease. Several studies have shown that the QoL of uveitis patients is reduced when compared with that of general population. Moreover, several socio-demographic and clinical related characteristics have been associated with impaired QoL. However, no longitudinal analysis of the vision-related (VR) QoL in clinical practice has been carried out.Objectives:To describe VR-QoL in non-infectious uveitis (NIU) patients during a follow-up period of two years. Furthermore, to analyse the influence of socio-demographic, clinical and treatment factors on the progression of VR-QoL.Methods:Longitudinal prospective study which includes patients examined in a multidisciplinary tertiary uveitis clinic, with a diagnosis of NIU. In each of these patients a yearly determination of VR-QoL was carried out following the VFQ-25 questionnaire, finally including all those who had completed at least an initial questionnaire and a second one after two years of follow-up. Analysis of risk factors at baseline in repeated VFQ-25 measurements was carried out by generalized estimating equations (GEE) models. Variables related to demographic, clinical and treatment factors with a determination of p-value <0.15 were included in multivariable models, which were then compared using theQuasi Akaike Information Criteria(qAIC). A local Ethics Committee approved the execution of this project.Results:128 patients were included, 117 of which also had an evaluation after the first year of follow-up. 55.5% were female with a median age of 34 years at the start of symptoms and of 37 years at the moment of attending our clinic for the first time. First evaluation of VR-QoL was determined a median (p25-p75) of 6.1 (1.8-13.1) years after that first visit. The most frequent locations of NIU were anterior (41.1%), panuveitis (27.4%), posterior (16.1%) and intermediate (15.3%). At our first evaluation, 27.3% of patients were receiving treatment with topical steroids, 22.3% oral, 49.2% immunosuppressant drugs (both synthetic and/or biological) and 19.05% biological therapies. The median (p25-p75) VFG25 determinations at baseline, first and second years of follow-up were 0.87 (0.78-0.93), 0.88 (0.80-0.93) y 0.89 (0.81-0.94), with no significant differences (first year vs. Baseline p = 0.54; 2 years vs. Baseline p = 0.61).In the GEE multivariable models the presence at baseline of permanent incapacity due to NIU, concomitant thyroid disease, worse visual acuity, unilateral pattern, cataracts, retinal vasculitis, epiretinal membrane and use of azathioprine were independently associated with a worse VR-QoL (Table 1).Table 1.Risk factors related to VR-QoL in patients with NIUVariablesCoef. (IC 95%)p-valueVisual acuity23.6 (12.3 - 34.8)<0.01Permanent incapacity-24.8 (-33.7 - -15.9)<0.01Unilateral NIU-2.9 (-5.7 - -0.006)0.05Cataracts-5.2 (-10 - -0.3)0.037Vasculitis-13.3 (-23.4 - -3.1)0.011Epiretinal membrane-6.8 (-12.7 - -0.8)0.026Azathioprine-7.5 (-14.7 - -0.3)0.041Conclusion:During these two years of follow-up, no significant changes have taken place regarding VR-QoL in patients with NIU assessed at a tertiary centre. Other than visual acuity at baseline, certain ocular manifestations and clinical comorbidities have also been shown to have an independent effect on the VR-QoL of these patients.Disclosure of Interests:None declared

Abstract
Background:Disease Activity Score (DAS) is a continuous measure of Rheumatoid Arthritis (RA) activity, used in clinical practice for monitoring disease progression and for documenting treatment response. According to EULAR, the clinical desired target is to achieve a remission state (or failing that, low disease activity). However, the population of RA patients in this state could be heterogenous.Objectives:To characterize the level of heterogeneity of RA patients in remission by identifying clusters based on the DAS28 components; and to describe inter and intra-class cluster demographic and clinical characteristicsMethods:Patients from Hospital Clínico San Carlos cohort, stored in a departmental electronic health record from January 1st, 2000 to December 30th, 2018, diagnose with RA according ACR 1986/ 2010 criteria were eligible for this study. Only observations with a DAS28 Erythrocyte Sedimentation Rate (ESR) value < 2.6 value were considered. ESR, patient’s Global Health (GH), and tender and swollen joints were used for calculating the clusters. Different aggregation levels for joints were studied as well as the input variable types. Isolated joints, joints grouped by the type of affectation (swollen or tender) or anatomic location or laterality aggregation levels were considered. Variables expressed as present or absent (i.e. dichotomous), continuous (count of joins) and categorical (type of joints) were also studied. Gower’s distance, used for dealing with variables of different type, was employed to calculate the distance matrix. The number of suitable clusters was chosen from two to seven clusters based on the width value of a Silhouette analyses. Finally, Partitioning Around Medoids (PAM) was used as the clustering algorithm. Differences among clusters regarding demographic and clinical characteristics were analyzed using t-student chi2 test.Results:812 patients with 1,431 observations were analyzed in this study. The joint aggregation level which showed a highest Silhouette width value (0.708) was the anatomic one. In this aggregation level, five dichotomous variables (presence of tenderness and/or swelling in right and/or left shoulder, elbow, wrist, knee and hand (including both metacarpophalangeal and proximal interphalangeal joints) and two continuous variables (ESR and GH) were used. Two clusters were found: the cluster A) with 1,305 observations and 742 patients and the B) with 126 observations and 115 patients. Cluster b) had a statistically significant higher DAS28-ESR value (higher number of tender and swollen joints, and higher GH, but lower ESR), longer follow-up time (6.5 vs. 4.7 years), higher VAS-pain score (10 vs. 2), and higher HAQ score (0.25 vs. 0.12). In addition, the proportion of patients treated with oral corticosteroids (63% s. 50%) and biological therapy (29% vs. 12%) was higher.Conclusion:We have identified two clinically distinct populations of RA patients in remission according to DAS28-ESR <2.6. Each subgroup could be associated with different outcomes during follow-up, such as radiographic progression or risk of relapse.Disclosure of Interests:Alfredo Madrid García: None declared, Dalifer Freites Nuñez: None declared, Judit Font: None declared, Isabel Hernandez: None declared, Leticia León: None declared, Jose Ignacio Colomer: None declared, Isidoro González-Álvaro Grant/research support from: Roche Laboratories, Consultant of: Lilly, Sanofi, Paid instructor for: Lilly, Speakers bureau: Abbvie, MSD, Roche, Lilly, Benjamin Fernandez: None declared, J Angel Jover: None declared, Lydia Abasolo: None declared, Luis Rodriguez Rodriguez: None declared

Abstract
Placental syncytiotrophoblast (ST) is considered as the main placental endocrine tissue secreting progesterone, a steroid essential for maintenance of pregnancy. However, each step of progestins production has been poorly investigated in villous cytotrophoblast (VCT) regarding ST formation. We aimed to characterize progestins production during human differentiation of VCT into ST. VCTs were isolated from term placenta and cultivated, with or without forskolin (FSK), to stimulate trophoblast differentiation. Secreted progestins concentrations were determined by immuno-assay and Gas Chromatography-tandem mass spectrometry. Intracellular expression of cholesterol transporter and enzymes involved in steroidogenesis were studied by immunofluorescence, western-blot, and RT-qPCR. Progesterone and pregnenolone are produced by VCT and their secretion increases with VCT differentiation while 17-hydroxyprogesterone concentration remains undetectable. HSD3B1 enzyme expression increases whereas MLN64, the cholesterol placental mitochondrial transporter and P450SCC expressions do not. FSK induces progestins production. Progestins placental synthesis is effective since VCT and increases with ST formation thanks to mitochondria.

Abstract
BACKGROUND OR OBJECTIVES HIV/AIDS transmission in Ecuador is considered a concentrated epidemic; therefore, there are some studies on high risk groups but there is limited published data regarding the HIV/AIDS risk factors among adolescents of African descent. In this study, we sought to explore the determinants of HIV/AIDS-related knowledge and behavior among afro-descendant youths attending schools in the city of Esmeraldas, Ecuador. METHODS A cross-sectional survey among school-attending youths was conducted in Esmeraldas, Ecuador in 2010. Our target population was afro-descendant youths attending the last two years of high school. Thirty public high schools enrolling students in junior and senior years were identified. Outcome data were analyzed in the form of three composite variables. A multivariate linear regression model was built for each outcome. RESULTS A total of 213 school-attending afro-descendant youths aged 14 to 21 years old were enrolled in this study. Gender distribution was almost equal with a 1:1.17 male to female ratio. Overall, students in this population scored well in comprehensive knowledge of HIV with 88% having medium or higher knowledge. CONCLUSION AND GLOBAL HEALTH IMPLICATIONS Knowledge of HIV and its determinants was medium to high, but knowledge of sexually transmitted diseases was low among afro-descendant Ecuadorian adolescents in our study. Results of this study might be instrumental in facilitating decision-making processes related to the planning, implementation, and evaluation of HIV/AIDS prevention and control strategies in this specific population.

Abstract
BACKGROUND The nutrition transition continues to affect populations throughout the world. The added impact of market integration and urbanization exacerbates the impact of the nutrition transition upon Indigenous populations worldwide. OBJECTIVES This study aims to explore the nutritional concerns of the urban Kichwas community residing in the Andes highlands of Ecuador. STUDY DESIGN This is a qualitative study. METHODS Eight focus groups were conducted with Kichwas men and women in November 2015 in the Imbabura province of the Andes in Ecuador. DATA ANALYSIS Applied thematic analysis was used to analyze findings regarding nutrition. RESULTS The participants shared concerns regarding increased intake of fast food, poor meal timing, and a shift in the child's food preferences that rejects traditional foods. They attributed these concerns to urbanization resulting from an increase in dual-income households and a loss of cultural identity. CONCLUSIONS Synergistic cultural factors are related to nutritional concerns voiced by the urban Kichwas community. PUBLIC HEALTH IMPLICATIONS Syndemic theory is a useful interpretive lens regarding nutritional trends within the Kichwas communities as they relate to the increased risk of chronic disease.

Abstract
The neuropathological hallmark of the C9orf72 intronic hexanucleotide expansion in frontotemporal lobar degeneration (FTLD) and amyotrophic lateral sclerosis (ALS) is the presence of small ubiquitin/p62-positive and transactive response DNA binding protein 43 kDa (TDP-43)-negative cytoplasmic inclusions in several brain areas. The identification of this histopathological signature is highly predictive of an underlying mutation. In this study, we screened 1800 cases of the Barcelona IDIBAPS Brain Bank, independently of the clinical and final neuropathological diagnosis of the brain donor, for the presence of ubiquitin/p62-positive inclusions in the cerebellum (UPPI). Positive cases were also stained for dipeptide repeats. We identified a total of 21 donors with UPPI and in all of them the C9orf72 hexanucleotide expansion was genetically confirmed. Most donors had an FTLD or to a lesser extent ALS clinico-pathological phenotype. However, 3 cases had been previously classified as having clinically and neuropathologically Lewy body disease. Other co-existing pathologies, especially of the PART-type, were also frequently encountered. This study highlights the importance of the evaluation of ubiquitin/p62-positive cytoplasmic inclusions in all neurodegenerative diseases as a good screening method for the detection of C9orf72 expansion mutation, since this mutation is not rare and can overlap with other neurodegenerative entities.

Abstract
Objective
There has been a great interest in knowing the factors associated with progression of aortic stenosis to try to slow down this evolution.
Methods
We studied 283 patients with chronic ischemic heart disease recording a broad number of clinical, therapeutic and analytical variables including inflammation and mineral metabolism biomarkers. We analyzed if any of these factors is a determinant of progression to aortic stenosis, defined as an increase in maximum flow speed across the aortic valve of at least 0.5 m/s.
Results
20 patients (7%) progressed to aortic stenosis in 72.4 months of follow-up. Among the patients who developed aortic stenosis, a greater age, greater percentage of peripheral arterial disease (PAD), lower treatment with beta-blockers, estimated Glomerular Filtration Rate (eGFR), total cholesterol, LDL, High-sensitivity C-reactive protein (HS-CRP), high-sensitivity troponin, N-terminal pro b-type natriuretic peptide and galectin 3 were found.
The results of the multivariate analysis showed that plasma levels of Proprotein convertase subtilisin/kexin type 9 (PCSK9) [OR: 0.668 per every increase in 100.000 μg/ml CI (0.457–0.977); p=0.038], HS-CRP [OR: 1.034 per every increase in 1 mg/dl CI (1.005–1.063); p=0.022], dyslipidemia [OR: 4.622 CI (1.285–16.618); p=0.019], PAD [OR: 9.453 CI (1.703–52.452); p=0.010], and eGFR [OR: 0.962 CI (0.939–0.986); p=0.002], remained a parameter with the ability to independently predict the progression of aortic stenosis
Conclusions
In patients with chronic ischemic heart disease, low PCSK9 and high HS-CRP plasmatic levels, low eFGR, PAD and dyslipidemia were independent predictors of progression of aortic stenosis. More studies are needed to investigate the relationships between the progression of aortic stenosis PCSK9 and inflammation.

Abstract
Abstract
Pulmonary veno-oclussive disease (PVOD) is a rare form of pulmonary hypertension of poor prognosis and difficult diagnosis. A founder mutation in EIF2KA4 gene has been described in Iberian Romani patients with familial PVOD.
Aims
genetically and clinically characterize a cohort of Iberian Romani patients with familial PVOD. To perform the family screening, analyze the phenotype and socio-cultural determinants which may influence on disease's course and spreading.
Methods
Patients with familial PVOD were included from November 2011 until February 2019. Clinical and survival data were obtained from the Spanish National Registry of PAH. Genetic analysis of EIF2KA4 was performed in patients and relatives.
Results
13 index cases were included, all of them Iberian Romani, carrying the founder mutation (p.Pro1115Leu) in EIF2KA4. Genetic screening revealed 74 of healthy heterozygotes and 13 homozygotes: among them 10 affected and 3 unaffected at baseline assessment (7, 28 and 37 years old). More than half of their family members, including one complete family, refused genetic screening. The survival free of transplant or death was 77.3% and 52.4%, at 1 and 3 years, respectively.
Baseline characteristics Total n=23 Age, years (SD) 23.6 (11.8) Male sex, % 52.2 Functional class NYHA III-IV, % 85 Pulmonary vascular resistance, UW (SD) 10 (5.4) DLCO, % 31.1 6MWT, meters (SD) 352.4 (160) Lung transplant, % 47.8 Survival free of transplant 3 years, % 52.4 DLCO, diffusing capacity for carbon monoxide; 6MWT, 6-minute walk test.
Conclusions
Patients were seriously ill from a young age. They have early pregnancy and high number of children. The high frequency of endogamy in the Romani population is likely to have an important impact on the transmission of PVOD, as it would favor the appearance of new homozygous carriers. Currently, our major concern is the low range of family members that accepted to be studied, more than 50% of family members rejected genetic studies and counseling.

Abstract
This work addresses a fundamental question: To what extent is graphene graphite? In particular does 2D graphene have many of the same 3D mechanical properties as graphite, such as the bulk modulus and elastic constant c_{33}? We have obtained, for the first time, unambiguous Raman spectra from unsupported monolayer graphene under pressure. We have used these data to quantify the out-of-plane stiffness of monolayer graphene, which is hard to define due to its 2D nature. Our data indicate a first physically meaningful out-of-plane stiffness of monolayer graphene, and find it to be consistent with that of graphite. We also report a shift rate of the in-plane phonon frequency of unsupported monolayer graphene to be 5.4 cm^{-1} GPa^{-1}, very close to that of graphite (4.7 cm^{-1} GPa^{-1}), contrary to the previous value for supported graphene. Our results imply that monolayer graphene has similar in-plane and out-of-plane stiffnesses, and anharmonicities to graphite.

Abstract
OBJECTIVES This community-based study explores the syndemic nature of HIV/AIDS risk and resilience among Indigenous Kichwa communities in the province of Imbabura, Ecuador. This study elucidates individual and community-level factors that serve to exacerbate HIV/AIDS risk, as they relate to underlying macrolevel, structural forces. Critically, this study also elicited opportunities for community-based opportunities for resiliency from HIV/AIDS. STUDY DESIGN Exploratory qualitative study. METHODS Guided by syndemic theory, a qualitative study was conducted to explore HIV risk and resilience among Indigenous Kichwa communities in the Northern Andean highlands of Ecuador. Eight focus groups (n = 59) with men and women from two communities were conducted. The data were analyzed using applied thematic analysis techniques. RESULTS Identified risk factors for HIV/AIDS centered around the following themes: (1) parents leaving the community for work, (2) alcohol and drug consumption, (3) unprotected sex, and (4) barriers to health care. Identified HIV/AIDS resiliency factors included the preservation of Indigenous culture and family-focused interventions. CONCLUSIONS The identified risk factors for HIV/AIDS are interrelated within a complex syndemic relationship. The mutually reinforcing individual-level risk factors of substance abuse and risky sexual behavior coalesce with violence to exacerbate the risk for HIV/AIDS acquisition among Ecuadorian Highland Indigenous communities. Moreover, HIV/AIDS risk prevails in the macrolevel context of disproportionate unemployment among Indigenous peoples and a systematically fragmented healthcare system. It is critical that public health professionals work to revolutionize the systematic discrimination that underpins indigenous health disparities at-large.

Abstract
BACKGROUND Frontotemporal Dementia (FTD) is a heterogeneous group of disorders and the second most frequent cause of early onset dementia making it the highest number of inherited cases. REVIEW SUMMARY FTD is characterized by considerable variability in clinical, genetic and histopathologic features. Patients may present symptoms ranging from behavioural disturbances to different language disorders, with or without motor neuron disorders or associated parkinsonism. Atrophy in frontal and temporal lobes is the most relevant radiological finding. In the last 10 years, the knowledge of this clinical entity has undergone remarkable changes both genetically and histopathologically, which have served to establish more consistent clinical criteria. Until now, 10 genes causative of FTLD have been described and up to four different proteins causative of atrophy have been detected in aggregates. CONCLUSION This review is mostly addressed to clinicians and aims to provide basic knowledge of these neurodegenerative disorders and clarify the complex FTD scenario.

Abstract
Background The nutritional traffic light label (NTLL) has become one of the most used Front of Package labels (FOP’s) around the world, for its simple and easy to understand graphical system. In Ecuador, this labelling system has recently been implemented; then, this research aims to evaluate the use and knowledge of NTLL and its effectiveness as a public health promotion strategy. Method In a cross-sectional study at two different urban supermarkets in Quito-Ecuador, a survey was conducted in 73 participants to inquire about knowledge, perspectives and purchasing habits regarding the NTLL. Objective data obtained from pictures of the participants’purchase was compared with subjective data obtained from the survey. For categorical variables, Chi square or Fisher’s Exact test were used and variables with a statistical significance at α = 0.1 were included in multivariate logistic regression models. Results 88.7% of participants knew about the NTTL. 27.4% reported using the NTLL, while 28.4% of participants were observed to really use it. Significant associations between self-knowledge of the NTLL and education level (p = 0.007) or knowledge level (p = 0.001) were found. A significant association was also found between the refered use of the NTLL and the shopping influencing factor (p = 0.02). In the multivariate analysis an association between knowledge of the NTLL and observed use was found only when adjusted for the supermarket (p = 0.038). Conclusion This study found that the level of knowledge of the NTLL in the studied population was relatively high; however, both the referred and the observed use of the NTLL were low. Use and knowledge of the NTLL were associated with the socioeconomic and educational status of the participants. Thus, the change in nutritional patterns needs additional strategies to put the NTLL before the brand once customers make their purchases.

Abstract
Background We sought to identify if socioeconomic and demographic factors play a role in resident knowledge, attitude, and practice regarding Dengue, Chikungunya, and Zika in order to inform effective management procedures for disease prevention in Panama, a middle-income tropical country in Central America. All three are arthropod-borne viruses transmitted by Aedes mosquito vectors present in the focal region of Panama City, the largest city in Central America and an urban region of extreme socioeconomic polarization. Methods Between November 2017 and February 2018, we administered standardized, anonymous knowledge, attitude, and practice surveys to 263 residents split between two neighborhoods of high socioeconomic status (SES) and two neighborhoods of low SES. We then summed the knowledge, attitude, and practice scores respectively, and used linear and logistic regressions to quantify relationships with socioeconomic and demographic factors. Results Low-SES neighborhoods with high proportions of low income residents, residents over 70 years old had lower mean knowledge scores compared to other groups. Furthermore, residents in neighborhoods of low SES reported more mosquito biting relative to residents in neighborhoods of high SES, yet comparably lower level of concerns for disease transmission. Additionally, knowledge was lower for the more novel emergent threats of Chikungunya and Zika, compared to the endemic Dengue. Conclusion Findings suggest that low-SES neighborhoods with high proportions of low income, low education, and elderly residents should be targeted for outreach programs designed to prevent DENV, CHIKV, or ZIKV in Panama City. These outcomes support our initial hypotheses as lower relative knowledge and fewer practices related to the prevention of Dengue, Chikungunya, and Zika were found in low-SES neighborhoods. There is also a widespread lack of adequate knowledge regarding these diseases as well as low levels of concern in areas of highly reported mosquito biting. We provide suggestions for taking neighborhood socioeconomic status and specific aspects resident health literacy and attitude into account for creating more effective outreach campaigns as both endemic and novel arthropod-borne disease rates continue to increase throughout Latin America.

Abstract
BACKGROUND Long-term longitudinal studies with multimodal biomarkers are needed to delve into the knowledge of preclinical AD. Subjective cognitive decline has been proposed as a risk factor for the development of cognitive impairment. Thus, including individuals with SCD in observational studies may be a cost-effective strategy to increase the prevalence of preclinical AD in the sample. OBJECTIVES To describe the rationale, research protocols and baseline characteristics of participants in the Fundació ACE Healthy Brain Initiative (FACEHBI). DESIGN FACEHBI is a clinical trial (EudraCT: 2014-000798-38) embedded within a long-term observational study of individuals with SCD. SETTING Participants have been recruited at the memory clinic of Fundació ACE (Barcelona) from two different sources: patients referred by a general practitioner and individuals from an Open House Initiative. PARTICIPANTS 200 individuals diagnosed with SCD with a strictly normal performance in a comprehensive neuropsychological battery. MEASUREMENTS Individuals will undergo an extensive neuropsychological protocol, risk factor assessment and a set of multimodal biomarkers including florbetaben PET, structural and functional MRI, diffusion tensor imaging, determination of amyloid species in plasma and neurophthalmologic assessment with optical coherence tomography. RESULTS Two hundred individuals have been recruited in 15 months. Mean age was 65.9 years; mean MMSE was 29.2 with a mean of 14.8 years of education. CONCLUSIONS FACEHBI is a long-term study of cognition, biomarkers and lifestyle that has been designed upon an innovative symptom-based approach using SCD as target population. It will shed light on the pathophysiology of preclinical AD and the role of SCD as a risk marker for the development of cognitive impairment.

Abstract
Psychotic symptoms, defined as the occurrence of delusions or hallucinations, are frequent in Alzheimer disease (AD), affecting ~40 to 60% of individuals with AD (AD with psychosis (AD+P)). In comparison with AD subjects without psychosis, AD+P subjects have more rapid cognitive decline and poor outcomes. Prior studies have estimated the heritability of psychosis in AD at 61%, but the underlying genetic sources of this risk are not known. We evaluated a Discovery Cohort of 2876 AD subjects with (N=1761) or without psychosis (N=1115). All subjects were genotyped using a custom genotyping array designed to evaluate single-nucleotide polymorphisms (SNPs) with evidence of genetic association with AD+P and include SNPs affecting or putatively affecting risk for schizophrenia and AD. Results were replicated in an independent cohort of 2194 AD subjects with (N=734) or without psychosis (N=1460). We found that AD+P is associated with polygenic risk for a set of novel loci and inversely associated with polygenic risk for schizophrenia. Among the biologic pathways identified by the associations of schizophrenia SNPs with AD+P are endosomal trafficking, autophagy and calcium channel signaling. To the best of our knowledge, these findings provide the first clear demonstration that AD+P is associated with common genetic variation. In addition, they provide an unbiased link between polygenic risk for schizophrenia and a lower risk of psychosis in AD. This provides an opportunity to leverage progress made in identifying the biologic effects of schizophrenia alleles to identify novel mechanisms protecting against more rapid cognitive decline and psychosis risk in AD.

Abstract
There is a reemergence of syphilis in the Latin American and Caribbean region. There is also very little information about HIV/Syphilis co-infection and its determinants. The aim of this study is to investigate knowledge, attitudes, and practices regarding sexually transmitted infections (STIs), in particular syphilis infection and HIV/Syphilis co-infection, as well as to estimate the prevalence of syphilis among men who have sex with men (MSM) in a city with one of the highest HIV prevalence rates in Ecuador. In this study, questionnaires were administered to 291 adult MSM. Questions included knowledge about STIs and their sexual practices. Blood samples were taken from participants to estimate the prevalence of syphilis and HIV/syphilis co-infection. In this population, the prevalence of HIV/syphilis co-infection was 4.8%, while the prevalence of syphilis as mono-infection was 6.5%. Participants who had syphilis mono-infection and HIV/syphilis co-infection were older. Men who had multiple partners and those who were forced to have sex had increased odds of syphilis and HIV/syphilis co-infection. A high prevalence of syphilis and self-reported STI was observed, which warrants targeted behavioral interventions. Co-infections are a cause for concern when treating a secondary infection in a person who is immunocompromised. These data suggest that specific knowledge, attitudes, and behaviors among MSM are associated with increased odds of STIs (including HIV/syphilis co-infections) in this region of Ecuador.
