Abstract
Introduction In 2017, Chile decriminalized abortion on three grounds: (i) if the pregnant person's life is at risk, (ii) fetal nonviability, and (iii) rape or incest. This multicase study explores the experiences of pregnant people legally entitled to but denied access to legal abortion in Chile. Methods Through a snowball sampling approach, we recruited adult Chilean residents who sought, were eligible for, and were denied a legal abortion after September 2017. We conducted semistructured interviews with participants to explore their experiences in seeking and being denied legal abortions. We recorded and transcribed the interviews, then coded and analyzed the transcriptions to identify common themes. Results We identified four women who met the eligibility criteria. The interviews revealed five common themes in their experiences: (i) disparate levels of social support in accessing abortion, (ii) abundant access barriers, (iii) forced pregnancy, (iv) abortion stigma, and (v) a failure of the law to provide access to abortion. Discussion and Health Equity Implications Although the 2017 law expanded legal access to abortion in Chile, significant barriers remain. Compounded with social stigma, and the socioeconomic disparities in abortion access, pregnant people continue to face insurmountable obstacles in obtaining legal abortions, even when their lives are at risk and the pregnancy is not viable. The state must prioritize equity of access to legal abortions. Future studies should continue to explore the challenges people face accessing legal abortion care to inform strategies to ensure people are able to obtain the quality care that they are legally entitled to.

Abstract
Tissue engineering (TE) and regenerative medicine offer strategies to improve damaged tissues by using scaffolds and cells. The use of collagen-based biomaterials in the field of TE has been intensively growing over the past decades. Mesenchymal stromal cells (MSCs) and dental pulp stem cells (DPSCs) are promising cell candidates for development of clinical composites. In this study, we proposed the development of a bovine collagen type I: chondroitin-6-sulphate (CG) scaffold, obtained from Uruguayan raw material (certified as free bovine spongiform encephalopathy), with CG crosslinking enhancement using different gamma radiation doses. Structural, biomechanical and chemical characteristics of the scaffolds were assessed by Scanning Electron Microscopy, axial tensile tests, FT-IR and Raman Spectroscopy, respectively. Once we selected the most appropriate scaffold for future use as a TE product, we studied the behavior of MSCs and DPSCs cultured on the scaffold by cytotoxicity, proliferation and differentiation assays. Among the diverse porous scaffolds obtained, the one with the most adequate properties was the one exposed to 15 kGy of gamma radiation. This radiation dose contributed to the crosslinking of molecules, to the formation of new bonds and/or to the reorganization of the collagen fibers. The selected scaffold was non-cytotoxic for the tested cells and a suitable substrate for cell proliferation. Furthermore, the scaffold allowed MSCs differentiation to osteogenic, chondrogenic, and adipogenic lineages. Thus, this work shows a promising approach to the synthesis of a collagen-scaffold suitable for TE.

Abstract
INTRODUCTION Theory of mind (ToM) is the human ability to perceive, interpret, and attribute the mental states of other people, and the alteration of this cognitive function is a core symptom of autistic spectrum disorder (ASD). In such other neurodevelopmental disorders as childhood-onset obsessive-compulsive disorder (OCD) and Tourette syndrome (TS) that can present with cognitive dysfunctions, ToM has been less extensively studied, especially in the young population. The aim of the study was to compare advanced ToM between groups of young people diagnosed with OCD, TS, or ASD and a control group. METHODS Clinical interviews were conducted with male patients aged between 11 and 17 years with a main diagnosis of OCD (n = 19), TS (n = 14), or ASD (n = 18), and a control group (n = 20). We administered instruments for estimating intelligence quotient and severity of psychiatric symptoms, and tasks to evaluate ToM (the "Stories from everyday life" task and the "Reading the mind in the eyes" test). RESULTS Young people with TS and with ASD present similar difficulties in solving advanced ToM tasks, whereas patients with childhood-onset OCD present similar results to controls. CONCLUSIONS ToM is altered in other neurodevelopmental disorders beyond ASD, such as TS.

Abstract
INTRODUCTION Access to comprehensive abortion care could prevent the death of between 13 865 and 38 940 women and the associated morbidity of 5 million women worldwide. There have been some important improvements in Latin America in terms of laws and policies on abortion. However, the predominant environment is still restrictive, and many women, adolescents and girls still face multiple barriers to exercise their reproductive rights. This research will systematically assess comprehensive abortion policies in five Latin American countries (Argentina, Colombia, Honduras, Mexico and Uruguay). The aim is to identify barriers, facilitators and strategies to the implementation of abortion policies, looking at four key dimensions-regulatory framework, abortion policy dynamics, abortion service delivery and health system and health outcomes indicators-to draw cross-cutting lessons learnt to improve current implementation and inform future safe abortion policy development. METHODS AND ANALYSIS A mixed-method design will be used in the five countries to address the four dimensions through the Availability, Accessibility, Acceptability and Quality of Care model. The data collection tools include desk reviews and semi-structured interviews with key actors. Analysis will be performed using thematic analysis and stakeholder analysis. A regional synthesis exercise will be conducted to draw lessons on barriers, facilitators and the strategies. ETHICS AND DISSEMINATION The project has been approved by the WHO Research Ethics Review Committee (ID: A66023) and by the local research ethics committees. Informed consent will be obtained from participants. Data will be treated with careful attention to protecting privacy and confidentiality. Findings from the study will be disseminated through a multipurpose strategy to target diverse audiences to foster the use of the study findings to inform the public debate agenda and policy implementation at national level. The strategy will include academic, advocacy and policy arenas and actors, including peer-reviewed publication and national and regional dissemination workshops.

Abstract
Access to emergency obstetric care, including assisted vaginal birth and caesarean birth, is crucial for improving maternal and childbirth outcomes. However, although the proportion of births by caesarean section has increased during the last few decades, the use of assisted vaginal birth has declined. This is particularly the case in low- and middle-income countries, despite an assisted vaginal birth often being less risky than caesarean birth. We therefore conducted a three-step process to identify a research agenda necessary to increase the use of, or reintroduce, assisted vaginal birth: after conducting an evidence synthesis, which informed a consultation with technical experts who proposed an initial research agenda, we sought and incorporated the views of women's representatives of this agenda. This process has allowed us to identify a comprehensive research agenda, with topics categorized as: (i) the need to understand women's perceptions of assisted vaginal birth, and provide appropriate and reliable information; (ii) the importance of training health-care providers in clinical skills but also in respectful care, effective communication, shared decision-making and informed consent; and (iii) the barriers to and facilitators of implementation and sustainability. From women's feedback, we learned of the urgent need to recognize labour, childbirth and postpartum experiences as inherently physiological and dignified human processes, in which interventions should only be implemented if necessary. The promotion and/or reintroduction of assisted vaginal birth in low-resource settings requires governments, policy-makers and hospital administrators to support skilled health-care providers who can, in turn, respectfully support women in labour and childbirth.

Abstract
In December of 2020, the Argentine Congress legalized abortion through 14 weeks, vastly increasing access to abortion care in the country. The law's passage followed years of advocacy for abortion rights in Argentina - including mass public and civil society mobilization, vocal support from an established pool of abortion providers who offered abortion services under specific legal exceptions prior to the new law, and the growth of community groups such as the Socorristas en Red who provide support for people to self-manage abortions. Aided by ample political will, the number of health facilities offering services increased substantially after the law was passed, and the public visibility around the law has helped assure people seeking abortion that it is their right. Proyecto mirar is an initiative focused on both gathering and using qualitative and quantitative data to inform stakeholders about the progress and obstacles of the law's implementation. In this review, we present an overall summary of the first two years of implementation of the abortion law in Argentina based on proyecto mirar data and contextualized through the historical processes that have contributed to the law's passage and application. While we see increases in abortion services and improved public perception around abortion rights, inequities in access and quality of care persist throughout the country. Specifically, providers in some regions are well trained, while others create obstacles to access, and in some regions health services provide high quality abortion care whereas others provide substandard care. To be sure, the implementation of public policies does not happen overnight; it requires government support and backing to tackle obstacles and solve implementation problems. Our findings suggest that when new abortion laws are passed, they must be supported by civil society and government leaders to ensure that associated policies are well crafted and monitored to ensure successful implementation.

Abstract
BACKGROUND Female sex workers (FSW) have been disproportionately impacted by the Covid-19 crisis. Data show increases of police violence toward key populations (KP), likely a consequence of their role in enforcing health government measures. This study aimed to identify factors associated with police violence experienced by FSW during the Covid-19 crisis in Argentina. METHODS EPIC is a multi-country, cross-sectional, community-based research program evaluating the impact of Covid-19 among KP. In Argentina, the study was conducted in collaboration with FSW community-based organizations (CBO). Participants completed an online survey (October 2020-April 2021). Police violence was measured as having experienced episodes of violence (physical, verbal, psychological or sexual) by security forces since the start of the health crisis. Factors associated with police violence were assessed in logistic regression models. RESULTS Among 173 respondents, median age was 34 [IQR 27-42], 39.3% were transgender women (TW), 78.1% declared sex work as their only income and 71.7% mentioned their financial situation has deteriorated with the health crisis. Nearly half of FSW (44.5%) reported experiencing police violence within the first year of the Covid-19 pandemic, and among them, 76.6% declared more frequent violence episodes since the beginning of the health crisis. After adjustment for age, being a TW (aOR [95% CI] = 2.71 [1.21;6.05]), reporting non-injection drug use (2.92 [1.02;8.36]), having a considerably deteriorated financial situation (3.67 [1.47;9.21]), having had a consultation with a CBO worker for medical care/treatments (5.56 [2.15;14.37]) and declaring fear or experiences of discrimination by physicians/other health workers (2.97 [1.21;7.29]), since the beginning of the Covid-19 health crisis, were independently associated with police violence. CONCLUSIONS FSW in Argentina have experienced an increase in police violence since the beginning of the health crisis. Belonging to multiple KP (FSW, TW, people who use drugs) increases the likelihood of experiencing police violence, highlighting the need of an intersectional approach to develop interventions to reduce stigma and violence against FSW. CBOs have provided essential support and services during the crisis to FSWs, and other KPs, who may have avoided traditional healthcare structures due to fear or experiences of discrimination.

Abstract
Biofilms are increasingly recognised as a critical global issue in a multitude of industries impacting health, food and water security, marine sector, and industrial processes resulting in estimated economic cost of $5 trillion USD annually. A major barrier to the translation of biofilm science is the gap between industrial practices and academic research across the biofilms field. Therefore, there is an urgent need for biofilm research to notice and react to industrially relevant issues to achieve transferable outputs. Regulatory frameworks necessarily bridge gaps between different players, but require a clear, science-driven non-biased underpinning to successfully translate research. Here we introduce a 2-dimensional framework, termed the Biofilm Research-Industrial Engagement Framework (BRIEF) for classifying existing biofilm technologies according to their level of scientific insight, including the understanding of the underlying biofilm system, and their industrial utility accounting for current industrial practices. We evidence the BRIEF with three case studies of biofilm science across healthcare, food & agriculture, and wastewater sectors highlighting the multifaceted issues around the effective translation of biofilm research. Based on these studies, we introduce some advisory guidelines to enhance the translational impact of future research.

Abstract
OBJECTIVES To explore obstetricians', midwives' and trainees' perceptions of caesarean section (CS) determinants in the context of public obstetric care services provision in Argentina. Our hypothesis is that known determinants of CS use may differ in settings with limited access to essential obstetric services. SETTING We conducted a formative research study in 19 public maternity hospitals in Argentina. An institutional survey assessed the availability of essential obstetric services. Subsequently, we conducted online surveys and semistructured interviews to assess the opinions of providers on known CS determinants. RESULTS Obstetric services showed an adequate provision of emergency obstetric care but limited services to support women during birth. Midwives, with some exceptions, are not involved during labour. We received 680 surveys from obstetricians, residents and midwives (response rate of 63%) and interviewed 26 key informants. Six out of 10 providers (411, 61%) indicated that the use of CS is associated with the complexities of our caseload. Limited pain management access was deemed a potential contributing factor for CS in adolescents and first-time mothers. Providers have conflicting views on the adequacy of training to deal with complex or prolonged labour. Obstetricians with more than 10 years of clinical experience indicated that fear of litigation was also associated with CS. Overall, there is consensus on the need to implement interventions to reduce unnecessary CS. CONCLUSIONS Public maternity hospitals in Argentina have made significant improvements in the provision of emergency services. The environment of service provision does not seem to facilitate the physiological process of vaginal birth. Providers acknowledged some of these challenges.

Abstract
Decades after incorporating plastics into consumer markets, research shows that these polymers have spread worldwide. Fragmentation of large debris leads to smaller particles, collectively called microplastics (MPs), which have become ubiquitous in aquatic environments. A fundamental aspect of understanding the implications of MP contamination on ecosystems is resolving the complex interactions of these artificial substrates with microbial cells. Using polystyrene microparticles as model polymers, we conducted an exploratory study where these interactions are quantitatively analyzed using an in vitro system consisting of single‐bacterial species capturing and aggregating MPs in water. Here we show that the production of Psl exopolysaccharide by Pseudomonas aeruginosa (PA) does not alter MPs colloidal stability but plays a key role in microspheres adhesion to the cell surface. Further aggregation of MPs by PA cells depends on bacterial mobility and the presence of sufficient flow to prevent rapid sedimentation of early MP‐PA assembles. Surprisingly, cells in MP‐PA aggregates are not in a sessile state despite the production of Psl, enhancing the motility of the aggregates by an order of magnitude relative to passive diffusion. The generated data could inform the creation of predictive models that accurately describe the dynamics and influence of bacterial growth on plastics debris.

Abstract
BACKGROUND Reliable and valid instruments are needed to estimate physical activity levels. The purposes of this study were to estimate the reliability and validity of the Physical Activity Questionnaire (MTPAQ) in a subsample of the Mexican Teachers Cohort study. METHODS We completed telephone interviews and clinical examinations of 82 teachers. Two MTPAQ, five International Physical Activity Questionnaire (IPAQ)-long form, and two accelerometer (AC) measures were used to determine physical activity levels throughout 24 months. Moderate and walking physical activity (MWPA min/week), vigorous physical activity (VPA min/week), and moderate-to-vigorous physical activity minutes per week (MVPA min/week) were estimated for each instrument. Pearson, Intra-class correlations and deattenuated adjustments were used to determine the reliability and validity of MTPAQ. RESULTS MWPA and MVPA min/week of MTPAQs were moderately correlated (r ≥ 0.54) to min/week of IPAQ-long form. MWPA and MVPA min/week average MTPAQ and MTPAQ1 and average AC, AC1 and AC2 were fairly correlated (r ≥ 0.20). A higher correlation was observed when correlation coefficients were attenuated (r ≥ 0.32). CONCLUSIONS MTPAQ1 is a reliable and valid tool to measure physical activity levels.

Abstract
Gel dosimeters, including radiochromic types like Fricke, as well as polymer formulations, are considered to be the only reliable option for accurate 3D dosimetry. Nevertheless, their implementation in daily clinical quality assurance still remains strongly limited for a few high specialized radiotherapy centres. Although gel dosimeters present very good water-equivalence due to their inherent chemical and isotopic compositions, addressing the corresponding dosimetry outputs is highly challenging, needing careful assessment in terms of the different radiation qualities involved in the mixed field. Accurate estimations of the linear energy transfer for each gel dosimeter formulation stands as a baseline for further accurate dose deconvolution in mixed radiation fields. The present study reports on the linear energy transfer characterization of five different gel dosimeter formulations, Fricke, Itabis, Magic, Nipam, and Pagat, for electron and proton therapeutic beams as obtained by Monte Carlo approaches, along with experimental results for validation purposes. The linear energy transfer, as a function of beam quality and penetration depth, is obtained for electron and proton therapeutic beams remarking the presence of non-negligible variations, which need to be accounted for a further accurate implementation of gel dosimetry as well as for precise dose deconvolution in mixed radiation fields.

Abstract
Abstract
Background
The impact of distance from residence to Tertiary Referral Hospital and cardiovascular (CV) outcomes in patients with coronary artery disease (CAD) is unknow. Despite longer travel distances hinder access to healthcare and may worsen CV outcomes, we hypothesize that Mediterranean lifestyle and behaviors in distant rural areas may be associated with a reduced risk of CV death and events.
Purpose
To investigate the association between travel distance to Tertiary Hospital and mid-term cardiovascular outcomes in a population of CAD patients in Southern Spain.
Methods
Retrospective study including all patients discharged after percutaneous coronary intervention (PCI) at a high-volume center in Southern Spain during 2018. Those belonging to another healthcare area were excluded. One-way driving distances from residence to hospital were computed using Google Maps Distance Matrix API with R package “gmapsdistance”. Patients were stratified into tertiles according to travel distance (short, STD; intermediate, ITD; and long, LTD). Kaplan-Meier (KM) and Multivariable Cox regression (adjusted for age, sex, atrial fibrillation, cancer history, prior revascularization and clinical presentation) were used to assess the impact of travel distance on CV death and a composite outcome of MACE (Myocardial Infarction, unplanned PCI and CV death).
Results
Of 1005 patients discharged after PCI during the study period, 966 met the selection criteria. Flowchart and baseline characteristics by distance groups are presented in Figure 1. Median travel distance tertiles were 6.1 (STD), 41.7 (ITD) and 78.4 (LTD). During a median follow-up of 31 (IQR 28–35) months, 50 cardiovascular deaths [STD 27 (8.4%), ITD 13 (4%), LTD 10 (3.1%), p=0.006)] and 63 MACE occurred [STD 45 (13.9%), ITD 37 (11.5%), LTD 26 (8.1%), p=0.060)]. KM curves for the three distance groups are shown in Figure 2. In univariable and multivariable Cox models, longer travel distances were associated with better outcomes, as for every 10 Km increase, there was a 11% and 7% decrease in the hazards of CV death (HR adj: 0.89, CI 0.82–0.98, p=0.029) and of MACE (HR adj: 0.93, CI 0.87–0.99, p=0.025), respectively.
Conclusion
Travel distance was inversely associated with CV events in a population of CAD patients in Southern Spain. Patients in the first tertile of distance had a higher rate of CV death. Multicenter studies involving other Mediterranean regions are needed to confirm these findings and to look for explanations.

Abstract
Abstract
Background
A physiological assessment with the fractional flow reserve (FFR) or instantaneous wave-free ratio (iFR) is strongly recommended by the European Guidelines of Revascularization to guide percutaneous coronary intervention (PCI) decision making in intermediate coronary stenosis. However, data supporting its use in the pro-inflammatory setting of ACS is weak.
Purpose
To analyze the usefulness of a physiological coronary evaluation with iFR of nonculprit lesions in patients with ACS.
Methods
Retrospective multicenter study including patients with ACS and underwent successful revascularization of the culprit vessel and had other nonculpritlesions physiologically evaluated with the iFR between January 2017 and December 2019. The primary endpoint was a composite of cardiac death, nonfatal myocardial infarction, stent thrombosis and new revascularization (MACEs).
Results
A total of 356 patients with 472 nonculprit lesions were included. The mean age was 66±11 years. The clinical presentation was non-ST-segment elevation myocardial infarction (NSTEMI) in 235 patients and ST-segment elevation myocardial infarction (STEMI) in 121 patients. After a mean follow-up period of 22±10 months, the primary endpoint occurred in 32 patients (9%). There were no differences in outcomes regarding iFR induced treatment strategy (patients with all lesions revascularized vs. patients with at least one lesion deferred for revascularization, 10.5 vs 8.4%, p=0.476).
Conclusion
The use of the iFR to guide percutaneous coronary intervention decision making in nonculprit lesions seems to be safe, with an acceptable percentage of MACEs at the mid-term follow-up.

Abstract
INTRODUCTION Abortion-related complications are a significant cause of morbidity and mortality among women in many Latin American and Caribbean (LAC) countries. The objective of this study was to characterise abortion-related complication severity, describe the management of these complications and report women's experiences with abortion care in selected countries of the Americas region. METHODS This is a cross-sectional study of 70 health facilities across six countries in the region. We collected data on women's characteristics including socio-demographics, obstetric history, clinical information, management procedures and using Audio Computer-Assisted Self-Interviewing (ACASI) survey the experience of abortion care. Descriptive bivariate analysis was performed for women's characteristics, management of complications and reported experiences of abortion care by severity of complications, organised in five hierarchical mutually exclusive categories based on indicators present at assessment. Generalised linear estimation models were used to assess the association between women's characteristics and severity of complications. RESULTS We collected data on 7983 women with abortion-related complications. Complications were classified as mild (46.3%), moderate (49.5%), potentially life-threatening (3.1%), near-miss cases (1.1%) and deaths (0.2%). Being single, having a gestational age of ≥13 weeks and having expelled products of conception before arrival at the facility were significantly associated with experiencing severe maternal outcomes compared with mild complications.Management of abortion-related complications included both uterotonics and uterine evacuation for two-thirds of the women while one-third received uterine evacuation only. Surgical uterine evacuation was performed in 93.2% (7437/7983) of women, being vacuum aspiration the most common one (5007/7437, 67.4%).Of the 327 women who completed the ACASI survey, 16.5% reported having an induced abortion, 12.5% of the women stated that they were not given explanations regarding their care nor were able to ask questions during their examination and treatment with percentages increasing with the severity of morbidity. CONCLUSIONS This is one of the first studies using a standardised methodology to measure severity of abortion-related complications and women's experiences with abortion care in LAC. Results aim to inform policies and programmes addressing sexual and reproductive rights and health in the region.

Abstract
INTRODUCTION Theory of mind (ToM) is the human ability to perceive, interpret, and attribute the mental states of other people, and the alteration of this cognitive function is a core symptom of autistic spectrum disorder (ASD). In such other neurodevelopmental disorders as childhood-onset obsessive-compulsive disorder (OCD) and Tourette syndrome (TS) that can present with cognitive dysfunctions, ToM has been less extensively studied, especially in the young population. The aim of the study was to compare advanced ToM between groups of young people diagnosed with OCD, TS, or ASD and a control group. METHODS Clinical interviews were conducted with male patients aged between 11 and 17 years with a main diagnosis of OCD (n=19), TS (n=14), or ASD (n=18), and a control group (n=20). We administered instruments for estimating intelligence quotient and severity of psychiatric symptoms, and tasks to evaluate ToM (the "Stories from everyday life" task and the "Reading the mind in the eyes" test). RESULTS Young people with TS and with ASD present similar difficulties in solving advanced ToM tasks, whereas patients with childhood-onset OCD present similar results to controls. CONCLUSIONS ToM is altered in other neurodevelopmental disorders beyond ASD, such as TS.

Abstract
Background While cesarean section is an essential life-saving strategy for women and newborns, its current overuse constitutes a global problem. The aim of this formative research is to collect information from hospitals, health professionals and women regarding the use of cesarean section in Argentina. This article describes the methodology of the study, the characteristics of the hospitals and the profile of the participants. Methods This formative research is a mixed-method study that will be conducted in seven provinces of Argentina. The eligibility criteria for the hospitals are (a) use of the Perinatal Information System, (b) cesarean section rate higher than 27% in 2016, (c) ≥ 1000 deliveries per year. Quantitative and qualitative research techniques will be used for data collection and analysis. The main inquiry points are the determining factors for the use of cesarean section, the potential interventions to optimize the use of cesarean section and, in the case of women, their preferred type of delivery. Discussion It is expected that the findings will provide a situation diagnosis to help a context-sensitive implementation of the interventions recommended by the World Health Organization to optimize cesarean section use. Trial registration IS002316 Plain English Summary Cesarean section is an essential medical tool for mothers and their children, but nowadays its overuse is a problem worldwide. Our purpose is to get information from hospitals, health professionals and women about how cesarean section is used in Argentina. In this protocol we describe how we will carry out the study and the characteristics of the hospitals and participants. We will implement this study in seven provinces of Argentina, in hospitals that have more than 1,000 births each year, had a cesarean section rate higher than 27% in 2016 and use the Perinatal Information System. We will gather information using forms, surveys and interviews. We want to identify the factors that decide the use of a cesarean section, the potential interventions that can improve the use of cesarean section and, in the case of women, the type of delivery they prefer. We expect that this study will give us a diagnosis of how cesarean section is used in Argentina, and that this will help to apply the interventions that the World Health Organization recommends to optimize the use of cesarean section in our specific context.

Abstract
Paracoccidioidomycosis (Pm) is a systemic disease, endemic in the American continent. There are two different clinical forms, the infant-juvenile or subacute form (PmS) and the chronic adult form (PmC). The human immunodeficiency virus (HIV) associated paracoccidioidomycosis (PmHIV) shares characteristics with both of the previously mentioned forms. The objective of this work was to describe the epidemiological, clinical and laboratory features of the PmHIV and to compare them with the ones of PmS and the PmC. A retrospective analysis of 119 patients with paracoccidioidomycosis was performed. Ninety four suffered the chronic form, 11 the subacute one and 14 were coinfected with HIV. Patients with PmHIV presented a CD4+ T lymphocytes median of 70.5 cells/μl, 71.4% had fever, 64.3% had a miliary pattern on the chest radiography, 64.3% had hepatosplenomegaly, 64.3% had mucosal lesions and 50% had skin lesions. One patient died during his hospitalization. The clinical presentation of Pm in patients with HIV resembled the subacute form with fever, hepatomegaly and skin lesions. However, they also tended to present mucosal lesions, positive serology for Pm and pulmonary parenchyma lesions as usually seen in PmC (9/14 PmHIV patients had overlapping features, while 4/14 PmHIV patients clinically resembled PmS and 1/14 PmC). The incidence of Pm has not changed with the burden of AIDS as it has happened with other fungal infections but it appears clinically different from the classic clinical forms of the disease.

Abstract
OBJECTIVES To evaluate via scanning electron microscopy the amount of smear layer generated during the use of sonic and ultrasonic activation systems with standardized short-term intentional contacts with the canal walls. METHODOLOGY Seventy single-root human teeth were randomly assigned to 2 control (n = 5 each): NC (negative control), PC (positive control) and four experimental groups (n = 15 each): NC (negative control), PC (positive control), G1 (passive ultrasonic irrigation with Irrisafe), G2 (ultrasonic irrigation with EndoUltra), G3 (sonic irrigation with Endoactivator), G4 (sonic irrigation with Eddy). Samples were instrumented with ProTaper Next®. An irrigation protocol with sodium hypochlorite (NaOCl) and ethylenediaminetetraacetic acid (EDTA) was followed for both PC and the experimental groups. Standardized intentional contacts were made in the mesial walls during 5 s at WL - 2 mm in all experimental groups. Two calibrated evaluators scored the smear layer generated with an ordinal scale by scanning electron microscopy. The weighted kappa coefficient (Kw) was calculated to determine the inter-observer agreement. Post-consensus ordinal data were analyzed using the ordinal (linear) chi-square test. RESULTS When the agitation file is in contact with dentine walls, Irrisafe® significantly generated the least amount of smear layer in the coronal third (p < 0.05). Both in the middle and apical third, activation with Irrisafe® also showed statistically significant better results than Eddy™ and EndoUltra®. Endoactivator® showed significant better results than EndoUltra® and Eddy™ in the apical third (p < 0.05). CONCLUSIONS Irrisafe generated the least amount of smear layer in the entire canal and similar to Endoactivator in the apical third when the agitation file is in contact with dentine walls. CLINICAL RELEVANCE The smear layer is generated during activation. It is common to apply irrigation protocols where after the removal of the smear layer using chelants, a final rinse and activation is carried out but there are no previous studies analyzing the possible creation of a new smear layer with this final activation.

Abstract
Background:Hip fracture is a frequent cause of hospital admission in older adults.1The prevalence of hip fracture associated with osteoporosis in the elderly is 18% in women and 6% in men.2Likewise, the attention of this event requires an approximate value of 2,943 dollars, which represents an average of 18,95% of the per capita income of most countries.3It is also established that appropriate and timely treatment of osteoporosis can prevent the appearance of fractures.4Objectives:The aim of this study was to determine the prevalence of hip fracture associated with osteoporosis, as well as the associated factors to its presentation in a geriatric population in Colombia.Methods:Cross-sectional study that included 130 patients over 65 years old, who consulted the University Hospital of Santander with hip fracture. The main variable of exposition was the medical history of osteoporosis. Descriptive analysis was performed with absolute and relative frequency measurements for the qualitative variables and central tendency measures and dispersion according to the distribution of the variables. Subsequently, the bivariate logistic regression analysis was performed to identify the associated risk variables. The analysis was performed with the Stata 12.0 Software.Results:From the 130 patients included in the study, 33.85% corresponded to the male gender. The average age was 82.49 years with a DS of 8.35 years. The median length of hospital stay was 17.5 days with an interquartile range of 11 to 26 days. The most common comorbidity was hypertension in 65.38%, followed by diabetes and COPD in 21.54%, heart failure in 19.23% and chronic kidney disease in 17.69%. The median Charlson score was 5 with an interquartile range between 4 and 6 points. 13.85% of the patients admitted had concomitant osteoporosis, 77.7% of them were women and 8,46% of them had severe osteoporosis, with history of prior fracture, without treatment. In the bivariate analysis, an association was found between having COPD (OR: 4.89, 95% CI 1.71-13.95, p = 0.003), dementia (OR: 3.20, 95% CI 1.05-19.56, p = 0.044), malnutrition (OR: 3.42, IC95 % 1.10 - 10.60, p = 0.032), and osteoporosis associated with hip fracture at hospital admission. Likewise, a greater probability was found for the development of in-hospital pneumonia (OR: 2.48, 95% CI 1.14 - 7.98, p = 0.04) in patients with osteoporosis compared to those who did not have bone disease.Conclusion:13.85% of patients who entered due to hip fracture had osteoporosis as comorbidity, data comparable to that previously reported. Variables associated with the presence of osteoporosis at admission in patients with hip fracture were found like history of COPD, dementia, and malnutrition, which makes it likely that those patients with pathologies that decrease physical activity or food intake can impact in an important way the appearance of osteoporosis. One of the most important contributions of this study is the identification of in-hospital complication (pneumonia), which should be actively monitored in these patients.References:[1]Falaschi P (Paolo), Marsh DR.

Abstract
The COVID-19 pandemic affected the organization of health services and had consequences for health teams, according to the pre-existing safety and working conditions. During the first week of April 2020, a cross sectional study was carried out with a qualitative-quantitative approach. The aim was to explore the conditions determining the organizational climate: leadership, communication, institutional resources, cohesion/conflict management, and training; and how these were perceived by health personnel to deal with the pandemic. A total of 5670 healthcare workers participated in an online survey and 50 were interviewed, from all subsectors of the Argentinean health system (public, private and union-health insurance); 72.9% were women, 51.4% were physicians, and the predominant age group was under 40 years. In the qualitative sample (interviews), 52% were men, 62% were physicians, and the average age was 44.8 years. The dimensions of the organizational climate were stratified and five independent predictors of perception of conditions were identified: age, gender, tasks performed, health system subsector, and jurisdiction. The condition most frequently perceived as inadequate were the inaccessibility of institutional resources and the access to personal protective equipment was a major concern. Claims included the need of institutional strategies to support healthcare workers and of a clear and uniform communication. In conclusion, at the time of the study, the health personnel perceived serious deficits in their organizations regarding the conditions necessary to confront COVID-19, with differences among subsectors of the health system.

Abstract
Abstract
Purpose
To analyze the feasibility and efficacy of the jailed pressure wire technique for bifurcation lesions treated by provisional stenting strategy and to assess the physiological side branch (SB) result using instantaneous wave free ratio (iFR).
Methods
Between June 2017 and December 2018, 50 patients who presented a bifurcation lesion considered appropriate for provisional stenting strategy were included in the study. Pressure wire was passed to side branch before treatment. Main vessel (MV) and side branch (SB) was predilated at the operator criteria. iFR determination was obtained in the SB baseline and after MV stenting (leaving the pressure wire jailed). Afterwards, the wire was removed to MV ostium to discard the possibility of drift. SB postdilation was performed if SB iFR was less than 0,89 (according to vessel thresholds established in clinical trials), evaluating the result by a new iFR determination.
Results
The mean age was 64±10 years. Sixteen patients (32%) had diabetes. Clinical presentation was stable angina in 26 patients (52%), non-STEMI in 19 patients (38%) and STEMI (non culprit lesion) in 5 patients (10%). The most frequent bifurcation type according to Medina classifications was 1,1,0 (21 patients, 42%). Seventeen patients (34%) had a true bifurcation lesion. The MV and SB reference diameter was 3,0±0,5 mm and 2,25±0,5 mm respectively. Most of the bifurcations were located at the left anterior descending artery/diagonal branch (27 bifurcations, 54%). Ten patients (20%) presented a distal left main bifurcation. Baseline SB iFR was 0,78±0,2. Under continuous SB iFR monitoring MV stenting was performed by trapping the pressure wire. After MV stenting, the SB iFR changed to 0,90±0,1. We confirmed the presence of drift in 5 patients (10%). In these cases, recalibration of the wire and SB rewiring was performed in 4 cases. In the remaining patient, rewiring was not possible even using specific coronary wires.
According to SB IFR, postdilation was necessary in 14 patients (28%). Final SB iFR was 0,94±0,03. A second stent was not necessary in any patient because final SB iFR was higher than 0.89 in all cases. We observed discordance between angiographic and physiological result in 17 cases (34%). All the wires could be removed. Forty wires (80%) were microscopically analyzed. Some grade of microscopic damage was found in 32 wires (80%), all of them distal to the pressure sensor. However, only one of these wires (2%) presented severe damage, and no case of fracture was observed.
After a mean follow up time of 10±6 months only one patient (2%) presented a major cardiac adverse event (acute coronary syndrome due to voluntary cessation of dual antiplatelet therapy).
Conclusions
The use of jailed pressure wire to monitor SB results for bifurcations treated by provisional stenting seems to be safe. The iFR index seems to provide new physiological information about the significance of the SB stenosis.

Abstract
OBJECTIVE Improve the performance of the regionalization policy in the province of Santa Fe, Argentina, as a strategy to improve perinatal health care by analyzing implementation processes and building consensus among decision makers and stakeholders around an action plan. METHODS Implementation research was conducted using mixed methodology. A needs assessment established tracer indicators to measure adherence to the components of the policy. Actors were studied to identify the barriers and facilitators of implementation. Training was provided on the development of consensus- and evidence-based policies, through workshops in which policy briefs were prepared and through a deliberative dialogue. RESULTS There were improvements in the number of births in appropriate hospitals and in the number of births in maternity hospitals with Essential Obstetric and Neonatal Care (CONE). Barriers were identified in the referral systems and in communication on policy, which resulted in an initial agreement on the need for guidelines and specific technical training on the transfer of babies and mothers. CONCLUSIONS The participation of health workers in identifying barriers and strategies to overcome them, and the use of tools to report this to management, permit the adoption of consensus- and evidence-based strategies to improve policy implementation.

Abstract
This article presents the findings of a qualitative study exploring the experiences of women living in Buenos Aires Metropolitan Area, Argentina, with the use of misoprostol for inducing an abortion. We asked women about the range of decisions they had to make, their emotions, the physical experience, strategies they needed to use, including seeking health care advice and in dealing with a clandestine medical abortion, and their overall evaluation of the experience. An in-depth interview schedule was used. The women had either used misoprostol and sought counselling or care at a public hospital (n=24) or had used misoprostol based on the advice of a local hotline, information from the internet or from other women (n=21). Four stages in the women's experiences were identified: how the decision to terminate the pregnancy was taken, how the medication was obtained, how the tablets were used, and reflections on the outcome whether or not they sought medical advice. Safety and privacy were key in deciding to use medical abortion. Access to the medication was the main obstacle, requiring a prescription or a friendly drugstore. Correct information about the number of pills to use and dosage intervals was the least easy to obtain and caused concerns. The possibility of choosing a time of privacy and having the company of a close one was highlighted as a unique advantage of medical abortion. Efforts to improve abortion law, policy and service provision in Argentina in order to ensure the best possible conditions for use of medical abortion by women should be redoubled.

Abstract
The effects of chronic consumption of oleuropein-enriched (15% w/w) olive leaf extract (OLE) on blood pressure, endothelial function, and vascular oxidative and inflammatory status in spontaneously hypertensive rats (SHR) were evaluated. Ten Wistar Kyoto rats (WKY) and twenty SHR were randomly assigned to three groups: a control WKY group, a control SHR group and a SHR group treated with OLE (30 mg kg(-1)) for 5 weeks. Long-term administration of OLE reduced systolic blood pressure, heart rate, and cardiac and renal hypertrophy. OLE treatment reversed the impaired aortic endothelium-dependent relaxation to acetylcholine observed in SHR. OLE restored aortic eNOS phosphorylation at Ser-1177 and Thr-495 and increased eNOS activity. OLE eliminated the increased aortic superoxide levels, and reduced the elevated NADPH oxidase activity, as a result of reduced NOX-1 and NOX-2 mRNA levels in SHR. OLE reduced the enhanced vascular TLR4 expression by inhibition of mitogen-activated protein kinase (MAPK) signaling with the subsequent reduction of proinflammatory cytokines. In conclusion, OLE exerts antihypertensive effects on genetic hypertension related to the improvement of vascular function as a result of reduced pro-oxidative and pro-inflammatory status.

Abstract
Ageing is characterized by increased low-grade chronic inflammation, which is a significant risk factor for morbidity and mortality of elderly individuals. Similar to ageing, obesity is considered to be an inflammatory predisposition associated with chronic activation of immune cells and consequent local and systemic inflammation. Both ageing and obesity are characterized by reduced innate and adaptive immune responses. This review focuses on B cells, how they may contribute, at least locally, to low-grade chronic inflammation in ageing and obesity and on the mechanisms involved.

Abstract
Edwardsiella tarda has long been known as a pathogen that causes severe economic losses in aquaculture industry. Insights gained on E. tarda pathogenesis may prove useful in the development of new methods for the treatment of infections as well as preventive measures against future outbreaks. In this report, we have established the correlation between the presence of virulence genes, related with three aspects typically involved in bacterial pathogenesis (chondroitinase activity, quorum sensing and siderophore-mediated ferric uptake systems), in the genome of E. tarda strains isolated from turbot in Europe and their phenotypic traits. A total of 8 genes were tested by PCR for their presence in 73 E. tarda isolates. High homogeneity was observed in the presence/absence pattern of all the strains. Positive results in the amplification of virulence-related genes were correlated with the detection of chondroitinase activity in agar plates, in vivo AHL production during fish infection and determination of type of siderophore produced by E. tarda. To the best of our knowledge, this is the first study carried out with European strains on potential virulence factors. Furthermore, we demonstrated for the first time that E. tarda produces the siderophore vibrioferrin.

Abstract
BACKGROUND AND PURPOSE Lipogenesis is intimately controlled by hormones and cytokines as well as nutritional conditions. IL-6 participates in the regulation of fatty acid metabolism in the liver. We investigated the role of IL-6 in mediating fasting/re-feeding changes in the expression of hepatic lipogenic enzymes. EXPERIMENTAL APPROACH Gene and protein expression of lipogenic enzymes were examined in livers of wild-type (WT) and IL-6-deficient (IL-6(-/-) ) mice during fasting and re-feeding conditions. Effects of exogenous IL-6 administration on gene expression of these enzymes were evaluated in vivo. The involvement of STAT3 in mediating these IL-6 responses was investigated by using siRNA in human HepG2 cells. KEY RESULTS During feeding, the up-regulation in the hepatic expression of lipogenic genes presented similar time kinetics in WT and IL-6(-/-) mice. During fasting, expression of lipogenic genes decreased gradually over time in both strains, although the initial drop was more marked in IL-6(-/-) mice. Protein levels of hepatic lipogenic enzymes were lower in IL-6(-/-) than in WT mice at the end of the fasting period. In WT, circulating IL-6 levels paralleled gene expression of hepatic lipogenic enzymes. IL-6 administration in vivo and in vitro showed that IL-6-mediated signalling was associated with the up-regulation of hepatic lipogenic enzyme genes. Moreover, silencing STAT3 in HepG2 cells attenuated IL-6 mediated up-regulation of lipogenic gene transcription levels. CONCLUSIONS AND IMPLICATIONS IL-6 sustains levels of hepatic lipogenic enzymes during fasting through activation of STAT3. Our findings indicate that clinical use of STAT3-associated signalling cytokines, particularly against steatosis, should be undertaken with caution.

Abstract
The quality of rice in terms not only of its nutritional value but also in terms of its aroma and flavour is becoming increasingly important in modern rice breeding where global targets are focused on both yield stability and grain quality. In the present paper we have exploited advanced, multi-platform metabolomics approaches to determine the biochemical differences in 31 rice varieties from a diverse range of genetic backgrounds and origin. All were grown under the specific local conditions for which they have been bred and all aspects of varietal identification and sample purity have been guaranteed by local experts from each country. Metabolomics analyses using 6 platforms have revealed the extent of biochemical differences (and similarities) between the chosen rice genotypes. Comparison of fragrant rice varieties showed a difference in the metabolic profiles of jasmine and basmati varieties. However with no consistent separation of the germplasm class. Storage of grains had a significant effect on the metabolome of both basmati and jasmine rice varieties but changes were different for the two rice types. This shows how metabolic changes may help prove a causal relationship with developing good quality in basmati rice or incurring quality loss in jasmine rice in aged grains. Such metabolomics approaches are leading to hypotheses on the potential links between grain quality attributes, biochemical composition and genotype in the context of breeding for improvement. With this knowledge we shall establish a stronger, evidence-based foundation upon which to build targeted strategies to support breeders in their quest for improved rice varieties.
