Abstract
Coupons of a medical grade PLDL polymer matrix uniaxially reinforced with a 15% volume fraction of Mg wires have been manufactured by fused filament fabrication for the first time. Two different types of Mg wires, without and with a surface treatment by plasma electrolytic oxidation were used. Both composite materials were subjected to degradation in phosphate buffer solution over a 3-week period, and their degradation and deformation micromechanisms were analysed in detail. Additionally, the materials were subjected to extensive mechanical testing under various loading conditions, and the interface strength was also analysed. It was found that the presence of the Mg wires improves the mechanical behaviour and accelerates the corrosion rate of the composite with respect that of the polymer matrix and these properties can be further tailored through the surface-modification of Mg wires by plasma electrolytic oxidation. The additive manufacturing strategy presented opens the path to fabricate multimaterial implants and scaffolds with complex shape and tailored properties provided by biodegradable polymers reinforced with either Mg and Zn particles and/or wires.

Abstract
INTRODUCTION We present the Spanish Society of Neurorehabilitation's guidelines for adult acquired brain injury (ABI) rehabilitation. These recommendations are based on a review of international clinical practice guidelines published between 2013 and 2020. DEVELOPMENT We establish recommendations based on the levels of evidence of the studies reviewed and expert consensus on population characteristics and the specific aspects of the intervention or procedure under research. CONCLUSIONS All patients with ABI should receive neurorehabilitation therapy once they present a minimal level of clinical stability. Neurorehabilitation should offer as much treatment as possible in terms of frequency, duration, and intensity (at least 45-60minutes of each specific form of therapy that is needed). Neurorehabilitation requires a coordinated, multidisciplinary team with the knowledge, experience, and skills needed to work in collaboration both with patients and with their families. Inpatient rehabilitation interventions are recommended for patients with more severe deficits and those in the acute phase, with outpatient treatment to be offered as soon as the patient's clinical situation allows it, as long as intensity criteria can be maintained. The duration of treatment should be based on treatment response and the possibilities for further improvement, according to the best available evidence. At discharge, patients should be offered health promotion, physical activity, support, and follow-up services to ensure that the benefits achieved are maintained, to detect possible complications, and to assess possible changes in functional status that may lead the patient to need other treatment programmes.

Abstract
The mechanical, thermal, and biological performance of fabrics manufactured with hybrid PLA/PCL commingled yarns were studied. Commingled hybrid yarns take advantage of the higher elastic modulus of PLA and the higher ductility and toughness of PCL to produce yarns and fabrics with high strength and ductility that is transferred to the woven textiles. Furthermore, PLA and PCL exhibit different degradation rates and also allow to tailor this property. Degradation of the textiles was carried out in phosphate-buffered saline solution for up to 160 days at 37 °C and 50 °C (accelerated degradation). Neither the thermal nor the mechanical properties were altered by immersion at 37 °C during 80 days and a slight degradation was observed as a result of chain scission of the PLA fibres after 160 days. However, immersion at 50 °C led to a rapid reduction in strength after 40 days due to the hydrolysis of PLA, and the fabric was highly degraded after 160 days as a result of chain scission in PCL. Finally, while indirect tests did not predict optimal biocompatibility, the direct tests provided a different perspective of the cell interaction between the textile and pre-osteoblasts regarding cell attachment and cell morphology. These results show the potential of hybrid commingled yarns to manufacture textile scaffolds of biodegradable polymers with tailored mechanical properties and good ductility for connective tissue engineering (ligaments and tendons).

Abstract
The study compared immunity to the original SARS-CoV-2 virus (Wuhan) and the Omicron variant using neutralizing antibodies (NAbs), that provide a good approximation of protective immunity. The results might help determine immunization strategies. DESIGN AND METHODS Unlike previous studies, we analyzed NAbs in a random sample of 110 IgG positive sera from individuals who participated in a population-based seroprevalence transversal study, carried out in May 2022 in two Chilean cities, a country with high vaccination coverage. RESULTS Our findings indicate that 98.2% of individuals had NAbs against Wuhan, 65.5% against Omicron, and 32.7% tested positive for Wuhan but not Omicron. Factors influencing protective immunity included a prior natural infection and the number of vaccines received. NAbs titers against the original virus were high, demonstrating vaccine effectiveness in the population. However, the level of antibodies decreased when measuring NAbs against Omicron, particularly among older individuals, indicating a decline in vaccine protection. Previous COVID-19 episodes acted as a natural booster, increasing NAbs titers against both virus strains. CONCLUSIONS Protective immunity against the original Wuhan SARS-CoV-2 virus is reduced when compared to Omicron variant. Updating vaccine to target emerging variants and continued monitoring of effectiveness at the population level are necessary.

Abstract
The outcome of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection in cancer pediatric patients was initially uncertain. The objective of this study was to describe the characteristics and outcome of cancer patients and hematopoietic stem cell transplant recipients from 0 to 19 years with detectable SARS-CoV-2 from April 23, 2020, to April 30, 2022, treated in a tertiary-level hospital in Argentina. A total of 348 cases were registered in 339 patients. The median age was 89.5 (3 to 224) months. The sex was predominantly male: 193 (55.5%). The most common malignant disease was leukemia (42.8%). One hundred four cases (29.9%) had comorbidities. Of the 346 cases with an available blood count, 17.6% had a lymphocyte count <300/mm 3 . Fever was the most common symptom. In most cases (93.1%) presented asymptomatic or mild disease. Twenty-one cases (6%) presented severe or critical status. Eleven of 24 admissions to the intensive care unit were due to COVID-19 (coronavirus disease 2019). Eight patients (2.3%) died. Two deaths were attributable to SARS-CoV-2 (0.6%). Being older, having fever, lymphopenia at diagnosis, and having received hematopoietic stem cell transplant were associated with a more severe disease. Around 90% of the children continued their cancer treatment without any change.

Abstract
Low-frequency mutations associated with drug resistance have been related to virologic failure in subjects with no history of pre-treatment and recent HIV diagnosis. In total, 78 antiretroviral treatment (ART)-naïve subjects with a recent HIV diagnosis were selected and followed by CD4+ T lymphocytes and viral load tests to detect virologic failure. We sequenced the basal samples retrospectively using next-generation sequencing (NGS), looking for low-frequency mutations that had not been detected before using the Sanger sequencing method (SSM) and describing the response to ART. Twenty-two subjects developed virologic failure (VF), and thirteen of them had at least one drug-resistance mutation associated with Reverse Transcriptase Inhibitors (RTI) and Protease Inhibitors (PIs) at frequency levels ≤ 1%, not detected previously in their basal genotyping test. No resistance mutations were observed to Integrase Strand Transfer Inhibitors (INSTIs). We identified a possible cause of VF in ART-naïve subjects with low-frequency mutations detected. To our knowledge, this is the first evaluation of pre-existing drug resistance for HIV-1 minority variants carried out on ART-naïve people living with HIV/AIDS (PLWHA) by analyzing the HIV-1 pol gene using NGS in the country.

Abstract
INTRODUCTION The extent of the population's exposure to tobacco imagery across all genres of regular TV programming and the contribution of each of these genres is unknown, except for UK broadcast channels. The objective of this study is to estimate the exposure of young people to tobacco imagery on Chilean prime-time television and the programme source contributing to such exposure. METHODS Programmes aired during 3 weeks in 2019 from the 15 highest audience channels in Chile were content-analysed for the occurrence of tobacco categorised as actual use, implied use, tobacco paraphernalia, tobacco brand appearances and whether they violated Chilean smoke-free law for each 1 min interval (92 639). The exposure of young people to tobacco content was estimated using media viewership figures. RESULTS Young people received 29, 11 and 4 million tobacco impressions of any type, explicit use and smoke-free violation, respectively, at a rate of 21.8, 8.0 and 2.1 thousand impressions per hour of TV viewing. The main sources of exposure to tobacco impressions were feature films and animated productions, which were almost entirely non-Chilean. Finally, young people were exposed to tobacco brand impressions primarily through films, effectively circumventing the advertising ban in Chile. DISCUSSION Television programming is a source of significant youth exposure to tobacco imagery, including branding impressions. To conform to the WHO FCTC, Chile should prohibit tobacco branding in any TV programme and require strong anti-tobacco advertisements prior to any TV programme portraying tobacco.

Abstract
During orthodontic treatment, diverse cytokines, enzymes, and osteolytic mediators produced within the teeth surrounding periodontal tissues determine the rate of alveolar bone remodeling and consequent teeth movement. In patients with teeth presenting reduced periodontal support, periodontal stability should be ensured during orthodontic treatment. Thus, therapies based on the application of low-intensity intermittent orthodontic forces are recommended. To determine if this kind of treatment is periodontally well tolerated, this study aimed to analyze the production of receptor activator of nuclear factor kappa-B ligand (RANKL), osteoprotegerin (OPG), interleukin (IL)-6, IL-17A, and matrix metalloproteinase (MMP)-8 in periodontal tissues of protruded anterior teeth with reduced periodontal support and undergoing orthodontic treatment. Patients with periodontitis-associated anterior teeth migration received non-surgical periodontal therapy and a specific orthodontic treatment involving controlled low-intensity intermittent orthodontic forces. Samples were collected before periodontitis treatment, after periodontitis treatment, and at 1 week to 24 months of the orthodontic treatment. During the 2 years of orthodontic treatment, no significant differences were detected in the probing depth, clinical attachment level, supragingival bacterial plaque, and bleeding on probing. In line with this, the gingival crevicular levels of RANKL, OPG, IL-6, IL-17A, and MMP-8 did not vary between the different evaluation time-points of the orthodontic treatment. When compared with the levels detected during the periodontitis, the RANKL/OPG ratio was significantly lower at all the analyzed time-points of the orthodontic treatment. In conclusion, the patient-specific orthodontic treatment based on intermittent orthodontic forces of low intensities was well tolerated by periodontally compromised teeth with pathological migration.

Abstract
BACKGROUND Chile has achieved the highest coverage for vaccines against the SARS-CoV-2 virus worldwide. OBJECTIVE To assess the progression of immunity (natural and acquired by vaccine) in a cohort from two Chilean cities. METHODS Individuals (n = 386) who participated in three phases of population-based serial prevalence studies were included (2020-2021 and 2022). Presence of SARS-CoV-2 antibodies was measured in serum. Data including time of vaccination and type of vaccine received were analysed with descriptive statistics. RESULTS Seroprevalence was 3.6% in the first round and increased to 96.9% in the second and 98.7% in the third. In the third round, 75% of individuals who had received the basal full scheme were seropositive at 180 days or more since their last dose; 98% of individuals who received one booster dose were seropositive at 180 days or more, and 100% participants who received two boosters were seropositive, regardless of time since their last dose. Participants receiving mRNA vaccines had higher seroprevalence rates over time. CONCLUSIONS The high vaccination coverage in Chile enabled the population to maintain high levels of antibodies. Vaccination boosters are essential to maintain immunity over time, which also depends on the type of vaccine administered.

Abstract
The gut microbiome can metabolise food components, such as dietary fibres and various phytochemicals; and the microbiome can also synthesise some nutrients, for example B vitamins. The metabolites produced by bacteria and other micro-organisms in the colon can have implications for health and disease risk. Some of these metabolites are epigenetically active, and can contribute to changes in the chemical modification and structure of chromatin by affecting the activity and expression of epigenetically-active enzymes, for example histone deacetylases and DNA methyltransferases. The epigenetic activity of such gut microbiome metabolites is reviewed herein.

Abstract
BACKGROUND The Coronavirus pandemic outbreak in 2019 and the saturation of healthcare system led to an increased use of digital tools for surveillance. In this study we described our experience using telemedicine to follow-up on patients with intraductal papillary mucinous neoplasms during the COVID-19 era and analyze those factors associated to patients' satisfaction. METHODS This 1-year retrospective observational study enrolled patients with intraductal papillary mucinous neoplasms followed-up by telemedicine during COVID-19 outbreak. Patients with high-risk features needing on-site physical examination or declining remote follow-up were excluded. A 13-question survey was conducted; demographic, geographic, and employment information was collected. Univariate and multivariate analyses were performed to evaluate those factors associated to patients' satisfaction. RESULTS Out of 287, a total of 177 patients with intraductal papillary mucinous neoplasms were included: the mean age was 69 (44-87) years and the male/female ratio was 0.78. A total of 80 (45.2%) patients had previously experienced abdominal pain. Most patients (85.3%) were satisfied with telemedicine: at univariate analysis, age ≥70 years (P = .007), retirement (P = .001), and absence of previous abdominal pain (P = .05) were significantly associated with patient satisfaction. At multivariate analysis, the absence of previous abdominal pain was the only factor independently associated with patient satisfaction (odds ratio 5.964, 95% confidence interval 2.21-16.11, P < .001). CONCLUSION Telemedicine allows a new follow-up strategy that can be used in selected patients with intraductal papillary mucinous neoplasms. The absence of previous abdominal pain is associated with patient satisfaction during follow-up. Further studies are needed to evaluate safety of remote follow-up in patients with intraductal papillary mucinous neoplasms.

Abstract
BACKGROUND The first wave of SARS-CoV-2 infection in Chile occurred during the cold season reaching a peak by the end of June 2020, with 80 % of the cases concentrated in its capital, Santiago. The main objective of this study was to estimate the attack rate during this first wave of SARS-CoV-2 in a large, densely populated city with more than seven million inhabitants. Since the number of confirmed cases provides biased information due to individuals' potential self-selection, mostly related to asymptomatic patients and testing access, we measured antibodies against SARS-CoV-2 to assess infection prevalence during the first wave in the city, as well as estimate asymptomatic cases, and infection fatality ratio. To our knowledge this is one of the few population-based cross-sectional serosurvey during the first wave in a highly affected emerging country. The challenges of pandemic response in urban settings in a capital city like Santiago, with heterogeneous subpopulations and high mobility through public transportation, highlight the necessity of more accurate information regarding the first waves of new emerging diseases. METHODS From April 24 to June 21, 2020, 1326 individuals were sampled from a long-standing panel of household representatives of Santiago. Immunochromatographic assays were used to detect IgM and IgG antibody isotypes. RESULTS Seroprevalence reached 6.79 % (95 %CI 5.58 %-8.26 %) in the first 107 days of the pandemic, without significant differences among sex and age groups; this figure indicates an attack rate 2.8 times higher than the one calculated with registered cases. It also changes the fatality rate estimates, from a 2.33 % case fatality rate reported by MOH to an estimated crude 1.00 % (CI95 % 0.97-1.03) infection fatality rate (adjusted for test performance 1.66 % [CI95 % 1.61-1.71]). Most seropositive were symptomatic (81,1 %). CONCLUSIONS Despite the high number of cases registered, mortality rates, and the stress produced over the health system, the vast majority of the people remained susceptible to potential new epidemic waves. We contribute to the understanding of the initial spread of emerging epidemic threats. Consequently, our results provide better information to design early strategies that counterattack new health challenges in urban contexts.

Abstract
Study question Do the different types of vaccines against SARS-CoV-2 influence the results of an Assisted Reproduction treatment? Summary answer The type of vaccine administered against SARS-CoV-2 does not affect the results in women performing an Assisted Reproduction treatment. What is known already Since the COVID-19 pandemic was declared, the search for vaccines has become the priority, so its development has represented a step towards herd immunity in a short period of time. Despite this encouraging advance, vaccine hesitancy in reproductive-aged women has been heightened because of the spread of misinformation stating that COVID-19 vaccines will cause sterility. Due to the lack of information and the clinical relevance, the objective of this work was to evaluate the impact of the different types of vaccines on women’s fertility. Study design, size, duration Retrospective and observational study during January-October 2021 in women vaccinated against SARS-CoV-2 and performing an Assisted Reproductive treatment in any of the 11 clinics belonging to the IVIRMA group in Spain. The Control group included patients performing a treatment during the same study period but who had not yet been vaccinated. The study was approved by an Institutional Review Board (2109-MADR-084-AR) Participants/materials, setting, methods All women, those who had received the complete vaccination schedule, regardless of the type of vaccine administered mRNA or viral vector, and women from the control group underwent the same ovarian stimulation protocol. The Assisted Reproduction treatment was performed with their own oocytes in all cases. Statistical analyses were performed using the Statistical Package for Social Sciences 19.0 (IBM Corporation, Armonk, NY, USA). Main results and the role of chance We included 510 patients distributed as follows: 13.5% (n = 69) received a viral vector vaccine either the adenovirus serotype 26 vector vaccine (Ad26.CoV2.S; Johnson & Johnson; n = 31) or the chimpanzee adenovirus vector vaccine (ChAdOx; AstraZeneca; n = 38). The remaining 86.5% (n = 441) received an mRNA vaccine from either Pfizer-BioNTech (n = 336) or Moderna (n = 105). Sample size for control group was n = 1190 Our results showed that women vaccinated with Johnson & Johnson have a higher average age (39.7 ± 4.3) than the other groups, although no statistical difference was observed (p = 0.072); that is, AstraZeneca (36.8 ± 1.7), Moderna (35.7 ± 1.5), Pfizer (34.6 ± 1.6) and the control group (37.8 ± 2.7). This circumstance did not affect other parameters such as the days of stimulation (p = 0.336) or the doses of FSH administered (p = 0.392), where no statistical differences were recorded between the vaccinated and the control group. Finally, the number of oocytes were as follows, Johnson & Johnson (9.2 ± 2.6), AstraZeneca (7.7 ± 1.2), Moderna (11.3 ± 1.8), Pfizer (12.6 ± 1.0), and the control group (10.2 ± 1.5), p = 0.06. Limitations, reasons for caution This is an observational study, and thus possible confounders cannot be excluded entirely. More data are needed to draw firm conclusions, and it will be critical to increase the sample size to check if the results observed in this work remains in the general population Wider implications of the findings This is the first study to assess whether the type of vaccine administered against SARS-CoV-2, mRNA, or viral vector, affects ovarian function in ART. These early findings suggest no measurable detrimental on ovarian response regardless of vaccine received. Trial registration number not applicable

Abstract
Using levels of neutralizing antibodies (nAbs), we evaluate the successful Chilean SARS-CoV-2 vaccine campaign, which combines different vaccine technologies and heterologous boosters. From a population-based study performed in November 2021, we randomly selected 120 seropositive individuals, organized into six groups of positive samples (20 subjects each) according to natural infection history and the five most frequent vaccination schemes. We conclude that the booster dose, regardless of vaccine technology or natural infection, and mRNA vaccines significantly improve nAbs response.

Abstract
Chile is among the most successful nations worldwide in terms of its COVID-19 vaccine rollout. By 31 December 2021, 84.1% of the population was fully vaccinated, and 56.1% received booster doses using different COVID-19 vaccines. In this context, we aimed to estimate the prevalence of anti-SARS-CoV-2 antibodies following the infection and vaccination campaign. Using a three-stage stratified sampling, we performed a population-based cross-sectional serosurvey based on a representative sample of three Chilean cities. Selected participants were blood-sampled on-site and answered a short COVID-19 and vaccination history questionnaire using Wantai SARS-CoV-2 Ab ELISA to determine seroprevalence. We recruited 2198 individuals aged 7–93 between 5 October and 25 November 2021; 2132 individuals received COVID-19 vaccinations (97%), 67 (3.1%) received one dose, 2065 (93.9%) received two doses, and 936 received the booster jab (42.6%). Antibody seroprevalence reached 97.3%, ranging from 40.9% among those not vaccinated to 99.8% in those with booster doses (OR = 674.6, 154.8–2938.5). SARS-CoV-2 antibodies were associated with vaccination, previous COVID-19 diagnosis, age group, and city of residence. In contrast, we found no significant differences in the type of vaccine used, education, nationality, or type of health insurance. We found a seroprevalence close to 100%, primarily due to the successful vaccination program, which strongly emphasizes universal access.

Abstract
Yeast selection for the wine industry in Spain started in 1950 for the understanding of the microbial ecology, and for the selection of optimal strains to improve the performance of alcoholic fermentation and the overall wine quality. This process has been strongly developed over the last 30 years, firstly on Saccharomyces cerevisiae, and, lately, with intense activity on non-Saccharomyces. Several thousand yeast strains have been isolated, identified and tested to select those with better performance and/or specific technological properties. The present review proposes a global survey of this massive ex-situ preservation of eukaryotic microorganisms, a reservoir of biotechnological solutions for the wine sector, overviewing relevant screenings that led to the selection of strains from 12 genera and 22 species of oenological significance. In the first part, the attention goes to the selection programmes related to relevant wine-producing areas (i.e. Douro, Extremadura, Galicia, La Mancha and Uclés, Ribera del Duero, Rioja, Sherry area, and Valencia). In the second part, the focus shifted on specific non-Saccharomyces genera/species selected from different Spanish and Portuguese regions, exploited to enhance particular attributes of the wines. A fil rouge of the dissertation is the design of tailored biotechnological solutions for wines typical of given geographic areas.

Abstract
The feasibility to manufacture scaffolds of poly-lactic acid reinforced with Zn particles by fused filament fabrication is demonstrated for the first time. Filaments of 2.85 mm in diameter of PLA reinforced with different weight fractions of μm-sized Zn - 1 wt.% Mg alloy particles (in the range 3.5 to 17.5 wt.%) were manufactured by a double extrusion method in which standard extrusion is followed by precision extrusion in a filament-maker machine. Filaments with constant diameter, negligible porosity and a homogeneous reinforcement distribution were obtained for Zn weight fractions of up to 10.5%. It was found that the presence of Zn particles led to limited changes in the physico-chemical properties of the PLA that did not affect the window temperature for 3D printing nor the melt flow index. Thus, porous scaffolds could be manufactured by fused filament fabrication at 190 °C with poly-lactic acid/Zn composites containing 3.5 and 7 wt.% of Zn and at 170 °C when the Zn content was 10.5 wt.% with excellent dimensional accuracy and mechanical properties.

Abstract
Background A major challenge of the SARS-CoV-2 pandemic is to better define “protective thresholds” to guide the global response. We aimed to characterize the longitudinal dynamics of the antibody responses in naturally infected individuals in Chile and compared them to humoral responses induced after immunization with CoronaVac-based on an inactivated whole virus -or the BNT162b2- based on mRNA-vaccines. We also contrasted them with the respective effectiveness and efficacy data available for both vaccines. Methods We determined and compared the longitudinal neutralizing (nAb) and anti-nucleocapsid (anti-N) antibody responses of 74 COVID-19 individuals (37 outpatient and 37 hospitalized) during the acute disease and convalescence. We also assessed the antibody boosting of 36 of these individuals who were immunized after convalescence with either the CoronaVac (n = 30) or the BNT162b2 (n = 6) vaccines. Antibody titres were also measured for 50 naïve individuals immunized with two doses of CoronaVac (n = 35) or BNT162b2 (n = 15) vaccines. The neutralizing level after vaccination was compared to those of convalescent individuals and the predicted efficacy was estimated. Findings SARS-CoV-2 infection induced robust nAb and anti-N antibody responses lasting >9 months, but showing a rapid nAb decay. After convalescence, nAb titres were significantly boosted by vaccination with CoronaVac or BNT162b2. In naïve individuals, the calculated mean titre induced by two doses of CoronaVac or BNT162b2 was 0·2 times and 5.2 times, respectively, that of convalescent individuals, which has been proposed as threshold of protection. CoronaVac induced no or only modest anti-N antibody responses. Using two proposed logistic models, the predicted efficacy of BNT162b2 was estimated at 97%, in close agreement with phase 3 efficacy studies, while for CoronaVac it was ∼50% corresponding to the lowest range of clinical trials and below the real-life data from Chile (from February 2 through May 1, 2021 during the predominant circulation of the Gamma variant), where the estimated vaccine effectiveness to prevent COVID-19 was 62·8–64·6%. Interpretation The decay of nAbs titres in previously infected individuals over time indicates that vaccination is needed to boost humoral memory responses. Immunization of naïve individuals with two doses of CoronaVac induced nAbs titres that were significantly lower to that of convalescent patients, and similar to vaccination with one dose of BTN162b2. The real life effectiveness for CoronaVac in Chile was higher than estimated; indicating that lower titres and additional cellular immune responses induced by CoronaVac might afford protection in a highly immunized population. Nevertheless, the lower nAb titre induced by two doses of CoronaVac as compared to the BTN162b2 vaccine in naïve individuals, highlights the need of booster immunizations over time to maintain protective levels of antibody, particularly with the emergence of new SARS-CoV-2 variants.

Abstract
BACKGROUND Seroprevalence studies provide an accurate measure of SARS-CoV-2 spread and the presence of asymptomatic cases. They also provide information on the uneven impact of the pandemic, pointing out vulnerable groups to prioritize which is particularly relevant in unequal societies. However, due to their high cost, they provide limited evidence of spatial spread of the pandemic specially in unequal societies. Our objective was to estimate the prevalence of SARS-CoV-2 antibodies in Chile and model its spatial risk distribution. METHODS During Oct-Nov 2020, we conducted a population-based serosurvey in Santiago, Talca, and Coquimbo-La Serena (2493 individuals). We explored the individual association between positive results and socio-economic and health-related variables by logistic regression for complex surveys. Then, using an Empirical Bayesian Kriging model, we estimated the infection risk spatial distribution using individual and census information, and compared these results with official records. RESULTS Seroprevalence was 10.4% (95% CI 7.8-13.7%), ranging from 2% (Talca) to 11% (Santiago), almost three times the number officially reported. Approximately 36% of these were asymptomatic, reaching 82% below 15 years old. Seroprevalence was associated with the city of residence, previous COVID-19 diagnosis, contact with confirmed cases (especially at household), and foreign nationality. The spatial model accurately interpolated the distribution of disease risk within the cities finding significant differences in the predicted probabilities of SARS-CoV-2 infection by census zone (IQR 2.5-15.0%), related to population density and education. CONCLUSIONS Our results underscore the transmission heterogeneity of SARS-CoV-2 within and across three urban centers of Chile. Socio-economic factors and the outcomes of this seroprevalence study enable us to identify priority areas for intervention. Our methodological approach and results can help guide the design of interdisciplinary strategies for urban contexts, not only for SARS-CoV-2 but also for other communicable diseases.

Abstract
BACKGROUND AND AIMS Emergency General Surgery (EGS) conditions account for millions of deaths worldwide, yet it is practiced without benchmarking-based quality improvement programs. The aim of this observational, prospective, multicenter, nationwide study was to determine the best benchmark cutoff points in EGS, as a reference to guide improvement measures. METHODS Over a 6-month period, 38 centers (5% of all public hospitals) attending EGS patients on a 24-h, 7-days a week basis, enrolled consecutive patients requiring an emergent/urgent surgical procedure. Patients were stratified into cohorts of low (i.e., expected morbidity risk <33%), middle and high risk using the novel m-LUCENTUM calculator. RESULTS A total of 7258 patients were included; age (mean ± SD) was 51.1 ± 21.5 years, 43.2% were female. Benchmark cutoffs in the low-risk cohort (5639 patients, 77.7% of total) were: use of laparoscopy ≥40.9%, length of hospital stays ≤3 days, any complication within 30 days ≤ 17.7%, and 30-day mortality ≤1.1%. The variables with the greatest impact were septicemia on length of hospital stay (21 days; adjusted beta coefficient 16.8; 95% CI: 15.3 to 18.3; P < .001), and respiratory failure on mortality (risk-adjusted population attributable fraction 44.6%, 95% CI 29.6 to 59.6, P < .001). Use of laparoscopy (odds ratio 0.764, 95% CI 0.678 to 0.861; P < .001), and intraoperative blood loss (101-500 mL: odds ratio 2.699, 95% CI 2.152 to 3.380; P < .001; and 500-1000 mL: odds ratio 2.875, 95% CI 1.403 to 5.858; P = .013) were associated with increased morbidity. CONCLUSIONS This study offers, for the first time, clinically-based benchmark values in EGS and identifies measures for improvement.

Abstract
Coronavirus 2 infection has spread rapidly throughout the world. Most of the current publications describe different behavior between an adult and pediatric population, this last one is associated with less clinical severity. The purpose of this study was to analyze the process of care, the epidemiological and clinical features, the evolution and the use of resources in pediatric patients with SARS-Cov-2 infection, treated during the first pandemic wave, at the beginning of 2020. An observational and retrospective study was carried out in the pediatric population with SARS-CoV-2 infection, treated in a highly complex pediatric hospital from April 1 to August 31, 2020. A total of 333 patients were included, 175 (53%) residents of the Metropolitan area of Buenos Aires (AMBA). The median age was 5.47 years (IQR 1.1-10.9) and 177 (53%) were women. A total of 209 (63%) patients required hospitalization and 152 (46%) had an underlying disease. Most of the patients (n 295, 89%) had mild/asymptomatic disease and the main symptom was fever (N169, 65%). In the univariate analysis, neurological disease (OR 4.5, IC95% 1.9-11, p 0.002), chronic respiratory disease (OR 3.9, IC95% 1.5-10.3, p 0.002) and genetics (OR 11, IC95%3.4-34.4, p < 0.001), as well as neurological symptoms (OR 2.8, IC95%1.1-6.6, p 0.035) and respiratory (OR 20.2, IC95%8.5-48.2, p 0.001) were associated with more severe disease. Active surveillance of pediatric patients with underlying diseases should continue to define the pandemic's impact on this specific population.

Abstract
The emergence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has caused a major international public health concern. The World Health Organization (WHO) declared the pandemic of coronavirus disease 2019 (COVID-19) on March 11, 2020. In Panama, the first SARS-CoV-2 infection was confirmed on March 9, 2020, and the first fatal case associated to COVID-19 was reported on March 10. This report presents the case of a 44-year-old female who arrived at the hospital with a respiratory failure, five days after the first fatal COVID-19 case, and who was living in a region where hantavirus pulmonary syndrome cases caused by Choclo orthohantavirus (CHOV), are prevalent. Thus, the clinical personnel set a differential diagnosis to determine a respiratory disease caused by the endemic CHOV or the new pandemic SARS-CoV-2. This case investigation describes the first coinfection by SARS-CoV-2 and CHOV worldwide. PCR detected both viruses during early stages of the disease and the genomic sequences were obtained. The presence of antibodies was determined during the patient’s hospitalization. After 23 days at the intensive care unit, the patient survived with no sequelae, and antibodies against CHOV and SARS-CoV-2 were still detectable 12 months after the disease. The detection of the coinfection in this patient highlights the importance, during a pandemic, of complementing the testing and diagnosis of the emergent agent, SARS-CoV-2, with other common endemic respiratory pathogens and other zoonotic pathogens, like CHOV, in regions where they are of public health concern.

Abstract
Background: The purpose of this study is to develop and validate a low-cost simulation model and training program for the acquisition of basic skills in endoscopic sinus surgery. Methodology: Experimental study. An eight-task low-cost simulation model was developed based on feeding bottles. Junior residents, general otolaryngologists, and fellowship-trained rhinologists (experts) were recorded performing each task. Operative time and number of errors were measured. Videos were evaluated by two blinded experts using a validated global rating scale (GRS) and a specific rating scale (SRS). A group of residents completed a six-session training program and then were recorded and evaluated using the same methodology. Results: Twenty-five participants were recruited. Statistically significant higher scores in the GRS and SRS and lower operative time and errors at higher levels of expertise were found. A significant correlation between SRS and GRS was found. Seven residents completed the training program. A significant improvement of SRS and GRS scores and reduction of operative time and errors were observed after training. Moreover, compared to experts, statistically significant fewer errors were made by residents after training, and no significant differences were found in terms of performance quality and operative time among these groups. Conclusions: Our low-cost simulation model can be accurately used as a validated objective assessment and training tool for basic endoscopic skills necessary for FESS, and can be potentially used in any otolaryngology surgical training program for residents.

Abstract
The pandemic caused by the SARS-CoV-2 virus declared by the WHO in March 11th 2020, affects a small number of pediatric patients, who mostly present mild respiratory compromise and favorable evolution. However began to be observed in previously healthy children, an increase in cases defined as "Multisystemic Inflammatory Syndrome" (MIS-C) or "Kawasaki-like" post-COVID 19 (KLC) that evolve to shock and require hospitalization in the Pediatric Intensive Care Unit. MIS-C and KL-C are characterized by fever; signs of inflammation, gastrointestinal symptoms, and cardiovascular dysfunction, associated with sever forms of presentation with higher incidence of hypotension and/or shock. In the laboratory, markers of inflammation, hypercoagulability and myocardial damage are observed. Firstline drug treatment consists of intravenous immunoglobulin plus oral acetylsalicylic acid. A multidisciplinary approach is recommended for an accurate diagnosis and an early and effective treatment, in order to reduce morbidity and mortality.

Abstract
Struvite from nutrient-rich wastewaters has been identified as a potential substitute for commercial mineral fertilisers, with the added benefit of reducing threats to global food security by prolonging phosphate rock reserves. A fertilisation test using grass (Brachiaria brizantha Marandú) and a sand column leaching test was conducted to determine the agronomic effectiveness of struvite precipitates produced from the supernatant of dewatered sewage sludge (centrate) from a municipal Wastewater Treatment Plant (WWTP). The performance of this struvite as a fertiliser was compared with biosolids and commercial fertilisers (Urea and Triple15). The results show that the concentration of heavy metals in struvite was lower than in biosolids and below the limits of Colombia and European fertiliser regulations. Struvite increased the uptake of N and P in grass, resulting in crop yields similar to other treatments tested. Struvite use as an effective slow-release fertiliser is highly dependent on the size of crystal particles, particularly in achieving low P losses, but resulted in high N loss in the sand columns tested; N loses from struvite were higher than in the commercial fertilisers due to the struvite small particle size. Therefore, struvite represents a suitable opportunity to recover and recycle nutrients from municipal sewage sludge, facilitating the effective reuse of P and N in agriculture and uptake by plants.

Abstract
The durability of circulating neutralizing antibody (nAb) responses to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection and their boosting by vaccination remains to be defined. We show that outpatient and hospitalized SARS-CoV-2 seropositive individuals mount a robust neutralizing antibody (nAb) response that peaks at days 23 and 27 post-symptom onset, respectively. Although nAb titers remained higher in hospitalized patients, both study groups showed long-lasting nAb responses that can persist for up to 12 months after natural infection. These nAb responses in previously seropositive individuals can be significantly boosted through immunization with two doses of the CoronaVac (Sinovac) or one dose of the BNT162b2 (BioNTech/Pfizer) vaccines, suggesting a substantial induction of B cell memory responses. Noteworthy, three obese previously seropositive individuals failed to mount a booster response upon vaccination, warranting further studies in this population. Immunization of naïve individuals with two doses of the CoronaVac vaccine or one dose of the BNT162b2 vaccine elicited similar levels of nAbs compared to seropositive individuals 4.2 to 13.3 months post-infection with SARS-CoV-2. Thus, this preliminary evidence suggests that both, seropositive and naïve individuals, require two doses of CoronaVac to ensure the induction of robust nAb titers.

Abstract
Ecuador is a signatory of the Stockholm Convention on chemical substances and hazardous waste and is responsible for complying with the guidelines for the environmentally adequate disposal of Polychlorinated Biphenyls (PCBs) in the country until 2025. The global management of PCBs begins with the sampling of transformers, analysis of dielectric oil, characterization and final disposal of transformers, oil and PCB material belonging to the electricity sector and private owners. The information on the characterization of PCBs is recorded and stored in a computer system called the National PCB Inventory and Monitoring System (SNIS-PCB), in which, the information of 216,632 transformers must be recorded for the present investigation. In the past 2018, the system registered 90,346 transformers, equivalent to 40% of the inventory, 3,494 of them were contaminated and are owned by electricity companies, and it was estimated that there are 1,063 contaminated transformers from private owners. The objective of the research is to analyze the economic and technical feasibility of the technologies available and allowed in the national regulations for the final disposal of these hazardous wastes. According to the technical characteristics of the technologies, logistical limitations and quantity of PCBs in the country, it has been determined that Dichlorination is a technological option that can be used for the treatment of PCBs, also offering the opportunity of decontamination, reuse of the material, and it is friendly with the environment.

Abstract
OBJECTIVE To describe a group of patients with suspected acute invasive fungal rhinosinusitis (AIFRS) diagnosis, and identify factors associated with a greater risk of presenting this disease. DESIGN Non-concurrent cohort study. SETTING A single-centre non-concurrent follow-up of patients with suspected AIFRS between August 2015 and July 2018. PARTICIPANTS 50 inpatients referred due to suspected AIFRS at Hospital Clínico Universidad Católica based on the association of a predisposing factor (neutropenia/immunodeficiency/poorly controlled diabetes) with fever of unknown origin. MAIN OUTCOME MEASURE The primary outcome was AIFRS diagnosis, defined as a concordant tissue biopsy. RESULTS Acute invasive fungal rhinosinusitis was confirmed in 18% (9/50) of the evaluated patients. AIFRS was significantly associated with a positive galactomannan (P = .04), and a paranasal sinus MRI with lack of contrast enhancement (LoCE) (P = .04) orbit compromise (P = .03) or global extrasinusal extension (P = .04). LoCE and extrasinusal extension in the paranasal sinus/brain MRI were risk factors for AIFRS (OR 16; CI 1.2-210.6 and OR 12.75; CI 1.3-128.8, respectively). Conversely, a nasal endoscopy showing healthy mucosa was identified as a protective factor for AIFRS (OR 0.06; CI 0.007-0.57). CONCLUSIONS In patients with suspected AIFRS, we identified laboratory and radiologic variables associated with the disease, which may help for a more accurate diagnostic algorithm and approach in this population.

Abstract
Single-exon coding sequences (CDSs), also known as ‘single-exon genes’ (SEGs), are defined as nuclear, protein-coding genes that lack introns in their CDSs. They have been studied not only to determine their origin and evolution but also because their expression has been linked to several types of human cancers and neurological/developmental disorders, and many exhibit tissue-specific transcription. We developed SinEx DB that houses DNA and protein sequence information of SEGs from 10 mammalian genomes including human. SinEx DB includes their functional predictions (KOG (euKaryotic Orthologous Groups)) and the relative distribution of these functions within species. Here, we report SinEx 2.0, a major update of SinEx DB that includes information of the occurrence, distribution and functional prediction of SEGs from 60 completely sequenced eukaryotic genomes, representing animals, fungi, protists and plants. The information is stored in a relational database built with MySQL Server 5.7, and the complete dataset of SEG sequences and their GO (Gene Ontology) functional assignations are available for downloading. SinEx DB 2.0 was built with a novel pipeline that helps disambiguate single-exon isoforms from SEGs. SinEx DB 2.0 is the largest available database for SEGs and provides a rich source of information for advancing our understanding of the evolution, function of SEGs and their associations with disorders including cancers and neurological and developmental diseases.

Abstract
There is limited evidence regarding severe acute respiratory syndrome coronavirus 2 infection in the placenta of pregnant women who tested positive, and if this could be a route for vertical transmission of the virus in utero. We present the cases of 2 pregnant women in their third trimester who were admitted for delivery by cesarean delivery and who, through universal screening, tested positive for coronavirus disease 2019. The maternal and fetal sides of the placenta were sectioned from both patients for viral analysis. Real-time polymerase chain reaction analysis of the placental-extracted RNA revealed a severe acute respiratory syndrome coronavirus 2 infection on the fetal side of the placenta in both patients. The virus was isolated from the patient with the lowest cycle threshold value on the fetal side of the placenta. Whole genome sequencing showed that the virus detected in this placenta was from the B1 lineage. Immunohistochemical analysis of the placental tissue detected severe acute respiratory syndrome coronavirus 2 in the endothelial cells of chorionic villi vessels proximal to both the maternal and fetal sides, with a granular cytoplasmic pattern and perinuclear reinforcement. Histologic examination of the placenta also detected a dense infiltrate of lymphoid cells around decidual vessels and endothelial cells with cytopathic changes, especially on the maternal side. Nasopharyngeal swabs from the infants that were subjected to reverse transcription quantitative polymerase chain reaction testing were negative for severe acute respiratory syndrome coronavirus 2 at 24 hours after birth. A follow-up analysis of the infants for immunoglobin G and immunoglobin M expression, clinical manifestations, and long-term developmental abnormalities is recommended.

Abstract
Introduction Coronavirus disease 2019, or COVID-19, has become a global pandemic. Given that the highest viral load of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is found in the airway, otolaryngologists are at high risk of infection. As a result, multiple recommendations have emerged regarding protective measures for surgical teams, including suspending non-urgent procedures and surgeries. Objectives To evaluate the impact of the COVID-19 pandemic on otolaryngology residency training programs nationwide. Methods A cross-sectional survey-based study was completed in April 2020. The participants were recruited through an online survey, sent by email to all Chilean otolaryngology residents. Demographics, clinical activities, on-call shifts, COVID-19 infection status, exposure to COVID-19 patients, deployment to other specialties, diagnostic/therapeutic procedures, and surgeries performed were analyzed. Self-reported surgical data logs from previous years were used to compare results. Results Forty-seven residents completed the survey (84% response rate); 64% of residents refer seeing patients ten days or less during April 2020. Commonly performed procedures such as flexible nasolaryngoscopy, rigid nasal endoscopy, and peritonsillar abscess drainage were not performed by over 40% of the residents in that month. Only 38% participated in surgeries, with an average of 0.6 surgeries as a first surgeon, a dramatic decrease in surgical exposure when comparing the data logs from previous years. Most residents refer the following measures taken by their residency program to improve residency training: bibliographic videoconferences (87%), online clinical case seminars (60%), weekly journal clubs (38%), among others. Conclusions Clinical and surgical opportunities decreased dramatically during April 2020. Adjustments to the regular academic curricula should be considered to decrease the negative impact of this pandemic on residency training.

Abstract
INTRODUCTION The aim of the study is to assess the national level of compliance with the Chilean smoke-free legislation in the urban public transportation system. METHODS In this cross-sectional observational study, we studied a national representative sample of 475 vehicles obtained through a two-stage cluster sampling design in 2018. First, 57 municipalities were randomly selected, proportionally to the total number of public transportation vehicles. Second, within each municipality, a convenience sample of up to 4 taxis, 4 buses, and 2 metro coaches was observed. We determined the non-compliance level by systematic direct observation of smoking inside the cabin of the vehicle. We estimated the percentage of the visited vehicles where smoking was observed inside the cabin of the vehicle. RESULTS The observation of metros, buses and taxis was completed in 24, 52, and 48, of the 57 sampled municipalities, respectively. Smoking was observed inside of about 2% of buses and 7% of taxis. Smoking was not observed in metro carriages. Overall, smoking was observed in almost 3% of the vehicles studied. A 3% noncompliance could expose a significant number of persons in public transportation to secondhand smoke, given that every 100 inhabitants results in about 84 rides a day of almost one hour duration. There are few comparable studies to put in an international context our results. In 2018, the year in which we collected the data, WHO considered that compliance with the law in public transportation was maximum. Our compliance estimate was lower, however WHO used a different methodology and its scope also included the inter-urban mobility, which we did not. CONCLUSIONS The study highlights the need to improve the enforcement of the smoke-free law in the transportation system in Chile, which presently is almost non-existent.

Abstract
OBJECTIVE To assess the national level of compliance with the Chilean comprehensive smoke-free legislation by observing healthcare facilities, education centres, government offices, hospitality venues and private workplaces, by type of area within workplaces and public places: enclosed, semiopen and open. METHODOLOGY In this cross-sectional observational study, we studied a national representative sample of 3253 venues obtained through a two-stage cluster sampling design. First, 57 municipalities were randomly selected, proportionally to the total number of venues of interest. Second, within each selected municipality, a maximum of 12 venues of each sector was selected systematically from a list of existing sites. We determined the non-compliance level by estimating the percentage of the visited venues where smoking was observed or suspected in banned areas of the premises. RESULTS Smoking or suspicion thereof was not observed in any enclosed area of any establishment. However, smoking violations were observed in semiopen areas ranging from less than 0.5% of schools and healthcare centres to around 10% of hospitality venues or 23.0% of higher education centres. Smoking violations were also observed in outdoor areas of 6.7% and 1.6% of the health centres and schools, respectively. DISCUSSION The stark contrast in compliance with the smoking ban between the enclosed areas and the semiopen areas may be a consequence of the complex definition of semiopen areas in the regulations. The study also reflects the need to improve the overall enforcement of the smoke-free law, particularly in universities and hospitality venues.

Abstract
INTRODUCTION Acute invasive fungal rhinosinusitis (AIFRS) is rare but has high mortality. It is more frequent in immunocompromised patients with multiple comorbidities, which make their management more difficult. The aim of this study is to describe a cohort of patients operated due to AIFRS, their clinical characteristics, mortality, aetiological agent and efficacy of diagnostic tests. MATERIAL AND METHOD Non-concurrent prospective study of patients with AIFRS who were operated between 2005 and 2015 in our centre. RESULTS Thirty-two patients were included, 62.5% (20/32) men, with an average age of 39.4 years (16-65 years). Overall mortality was 71.9%; acute mortality 46.9% and late mortality 25%. Haematological malignancies were the most common underlying disease, present in 84.4% (27/32) of cases, followed by diabetes mellitus in 9.4% (3/32). On diagnosis, 62.5% (20/32) of patients were neutropenic, 80% (16/20) of them with febrile neutropenia. Fever was the most frequent symptom, present in 65.6% (21/32) of patients, followed by facial pain or headache in 53.1% (17/32). Aspergillus was identified in 37.5% (12/32) of cases and Rhizopus in 31.3% (10/32). There was no association between the analysed variables and increased risk of mortality. CONCLUSIONS AIFRS is an aggressive disease with a high mortality rate, therefore a timely diagnosis is fundamental. It is necessary to optimise suspicion criteria for an early diagnosis in order to improve the prognosis.

Abstract
BACKGROUND Exhausted sugar beet pulp pellets (ESBPP), a sugar industry by-product generated after sugar extraction in the sugar production process, have been used as a raw material for lactic acid (LA) production via hydrolysis and fermentation by Lactobacillus casei. To design a more cost-effective process, simultaneous saccharification and fermentation (SSF) of ESBPP is proposed in the present study. The effects of pH control, nutrient supplementation and solid addition in fed-batch SSF on lactic acid production were investigated. RESULTS The highest LA concentration (26.88 g L-1 ) was reached in fed-batch SSF at a solid/liquid loading of 0.2 g mL-1 , with pH control (by adding 30 g L-1 CaCO3 to the medium) and nutrient supplementation (by adding 20 mL of MRS medium per 100 mL of buffer). Under these conditions, a maximum productivity of 0.63 g L-1 h-1 was achieved, which is 2.7 times higher than that attained in the control experiment (SSF inoculated at time 0 h). However, a slightly lower LA yield was obtained, revealing the need of an increasing dose of enzymes at high solid loading SSF. CONCLUSION An efficient fed-batch SSF strategy with pH control and MRS supplementation is described in the present study, attaining higher LA productivity compared to separate hydrolysis and fermentation and SSF. © 2020 Society of Chemical Industry.

Abstract
IntroductionThe hormonal imbalance produced by antipsychotics can be detected by symptoms, such as: infertility, acne, hirsutism, sexual dysfunction and galactorrhea. We consider especially important the study of women's diseases, which may develop due to hyperprolactinemia, specifically: breast cancer, endometrial cancer and osteoporosis.ObjectiveTo undertake a systematic review about the relationship between hyperprolactinemia as a result of the treatment with antipsychoticsand endometrial and breast cancer.MethodAn exhaustive search was performed on PUBMED and COCHRANE (from 2006 to 2015).Fifteen papers were selected including comparative studies, clinical trials and clinical reviews.ResultsWith respect to endometrial carcinoma, there is no direct relationship with the use of antipsychotics. However, most papers have suggested that the blood prolactin elevation is a risk factor in the development of endometrial engrossment, which could lead to endometrial hyperplasia, polyps and endometrial cancer. Related to the use of antipsychotics as a treatment for schizophrenic women and breast carcinoma, a significant association was found and this association is strengthened through the interaction of other factors like the fact that women with schizophrenia are less worried about going to the clinical screening reviews in their health centre, smoking, and lower physical activity than healthy women.ConclusionsAripiprazolis associated with a low prevalence of hyperprolactinemia. Menopausal women, the obese, and women who smoke receiving antipsychotics that produce hyperprolactinemia have the greatest risk of developing endometrial pathology. Schizophrenic women with hyperprolactinemia due to antipsychotics and loss of motivation to go to screening activities have a greater risk of breast cancer. Sexual dysfunction could be a non-adherence treatment factor.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Abstract
Objetivo: Conocer la percepción de informantes clave pertenecientes a la red de Atención Primaria de Salud en Chile, respecto al proceso de gestión asistencial y el impacto del programa nacional de Garantías Explícitas en Salud (GES) sobre la entrega de ayudas técnicas a personas mayores. Materiales y métodos: Un estudio cualitativo basado en análisis de casos múltiples, en el cual se realizó entrevistas semi-estructuradas a 8 informantes clave de la red asistencial, fue desarrollado en 2015 en tres comunas de Santiago, Chile. El análisis de la información recogida se realizó mediante análisis de contenido, y se finalizó el muestreo de máxima variación al saturar la información. Se resguardaron los criterios de rigor científico y el protocolo fue aprobado por un Comité de Ética. Resultados: Hay una percepción de cobertura y detección de necesidad como adecuada en pacientes bajo control, aunque desde la perspectiva de los informantes, hay desconocimiento de esta garantía en la población. La necesidad es detectada por cualquier profesional de salud, pero la indicación es exclusivamente médica, lo que genera barreras de acceso. Hay una entrega oportuna; sin embargo, no se realiza seguimiento ni se aprecia como parte de una atención integral. Se percibe que la ayuda técnica es de calidad y la articulación de la red es adecuada, aunque no hay retroalimentación a Atención Primaria de Salud. El impacto lo consideran positivo en pacientes y familiares: mejora la ejecución de actividades diarias y genera mayor autonomía y capacidad de desplazamiento. Conclusiones: Existe una percepción positiva de este programa GES y su impacto en la mejoría en la calidad de vida de vida de los pacientes. Pero, la entrega de ayudas técnicas se encuentra desvinculada de una atención integral, por ende, este programa prioriza sólo la garantía de oportunidad.

Abstract
Hypertension (HTN) in children and adolescents is an important pathology, of, guarded prognosis, associated with modifiable and non-modifiable factors. The estimated prevalence is around 3.5% which increases progressively with age. The ideal method for its diagnosis is the measurement of blood pressure (BP) with auscultatory instruments. According to the American Academy of Pedia trics (AAP), BP should be measured in children older than three years of age once a year, and in children younger than three years of age if they present risk factors. Once the HTN is confirmed, the evaluation should be directed towards the detection of a causative disease and/or the search for risk factors associated with a primary HTN. The objective of treating primary and secondary HTN in pediatrics is to achieve a BP level that decreases the risk of target organ damage. Therapeutic op tions include treatment according to specific etiology, non-pharmacological and pharmacological one. This paper presents the position of the Chilean Society of Pediatrics Nephrology Branch with the aim of guiding pediatricians and pediatric nephrologists in the correct management of HTN in childhood. In this second part, recommendations on antihypertensive treatment are presented with an emphasis on lifestyle changes.

Abstract
Ambulatory blood pressure monitoring (ABPM) is a useful clinical tool for the diagnosis and confir mation of arterial hypertension in pediatrics, and also allows the diagnosis of special conditions such as white coat hypertension and masked hypertension. There are international recommendations for its implementation and interpretation, however, there are still unresolved questions. This guide summarizes the available literature and attempts to standardize, through consensus of national specia lists, the application of this technique. More research studies are needed that provide new reference values and determine the relationship of alterations in ABPM with long-term clinical results.
