    Title translation Phosphodiesterase 5 inhibitors for the treatment of heart failure: a systematic review and meta-analysis.
    Abstract Objective: The treatment with phosphodiesterase-5 (PDE-5) inhibitors was postulated in heart failure (HF). We conducted a systematic review and a meta-analysis on their beneficial and adverse effects in patients with HF.
    Method: A meta-analysis of randomized trials evaluating the chronic use of PDE-5 inhibitors in patients with HF was conducted. Endpoints included death, HF hospitalizations, functional capacity, pulmonary pressures, quality of life, and adverse effects. Random-effects models were used to pool outcomes. Categorical data were summarized with relative risks (RR) and 95% confidence intervals (95%CI), and continuous data with weighted mean differences and standardized mean differences.
    Results: Sixteen studies (1119 participants) were included. No effect was observed on mortality (RR: 1.16; 95%CI: 0.50-2.66; I2: 0.0%) or HF hospitalizations (RR: 0.75; 95%CI: 0.41-1.37; I2: 38.7%). Treatment significantly reduced pulmonary systolic pressure (-10.64 mmHg; 95%CI: -5.14 to -16.15 mmHg; I2: 96.0%), and increased peak oxygen consumption (2.06 ml/kg/min; 95%CI: 0.40-3.72; I2: 89.6%), although with high inconsistency. There were no significant effects on quality of life (-0.15; 95%CI: -0.48-0.18; I2: 0.0%). On the other hand, the risk of headaches was increased (RR: 1.63; 95%CI: 1.11-2.39; I2: 0.0%). Publication bias was identified for HF hospitalizations.
    Conclusions: Current data suggest that PDE-5 inhibitors therapy does not improve prognosis or quality of life among HF patients. Hemodynamic and functional effects could be relevant, and more studies are necessary to define its role.

    Title translation Síndrome post COVID-19. Gravedad y evolución en 4673 trabajadores sanitarios.
    Abstract Background: The evolution of post COVID syndrome has been variable and we lack information on its impact on healthcare professionals, particularly in Latin America.
    Methods: We conducted a survey through a social network in health professionals on post COVID-19 syndrome cases confirmed with PCR. In a web-based questionnaire, we asked about 21 symptoms, their severity, duration, degree of activity impairment and return to work.
    Results: 4673 health professionals from 21 countries responded, mean age of 47.8 years, 64.2% women. The initial course was asymptomatic in 9.1%, mild symptoms 36.8%, moderate symptoms without hospitalization 40.8% or with hospitalization 11.7%, and severe symptoms with respiratory assistance 1.6%. The most prevalent symptoms were fatigue (67%), insomnia (44.2%), anxiety (42.3%), myalgia (41.9%) and anosmia (41.2%). Considering only severe symptoms (grades 3-4 on a subjective index from 1 to 4), the most prevalent were slowness (36.3%), impaired concentration (33.1%), anosmia (20.4%), fatigue (19.1%), impaired memory (18.1%) and dyspnea (15.9%). Prevalence dropped by half in the first 5 five months, but in many cases, it lasted for more than a year. In the multivariate analysis, symptoms tended to be grouped into clusters (cognitive, neuropsychiatric, cardiorespiratory, digestive, others). The need to change the work area was 16% and lack of return to work 7.8%, related to older age, number of symptoms and severity of the initial course.
    Conclusion: In conclusion, in many cases the persistence of post-COVID symptoms can be prolonged and have an occupational impact on healthcare professionals, requiring the adoption of specific policies to reduce harm.

    Abstract Objective: Evaluate primary health care functions from the perspective of patients with tuberculosis from slums in the city of Buenos Aires, Argentina.
    Methods: Cross-sectional observational study with adult patients with tuberculosis (TB) and without TB (NoTB), living in slums (S) and outside them (NoS). Participants' perceptions were evaluated using the Primary Care Assessment Tool for users (abbreviated version), which measures four main domains (first contact, ongoing care, coordination with specialists, and comprehensiveness) and selected secondary domains. A Likert scale was used, ranging from "No, not at all" (1 point) to "Yes, definitely" (4 points). Scores ≥ 3 were considered to indicate adequate performance of functions. Averages were calculated for each domain, as well as two overall scores: with and without secondary domains.
    Results: 83 participants were included (20 TB-S, 21 TB-NoS, 19 NoTB-S, and 23 NoTB-NoS). The evaluated functions were perceived as inadequate. The TB-S group gave the lowest overall scores, not reaching 3 points in any domain. There were no significant differences in domains or overall scores between groups. Participants with TB gave lower scores in all domains, except in family-centered care, where they gave a significantly higher score than NoTB participants. The overall score without secondary domains was lower for TB participants than for the NoTB groups.
    Conclusions: According to the perception of participants with TB and without TB, primary health care functions are not satisfactory, either in slums or outside them.

    Abstract Objective: To summarise the unfolding of the COVID-19 epidemic among slum dwellers and different social strata in the city of Buenos Aires during the first 20 weeks after the first reported case.
    Design: Observational study using a time-series analysis. Natural experiment in a big city.
    Setting: Population of the city of Buenos Aires and the integrated health reporting system records of positive RT-PCR for COVID-19 tests.
    Participants: Records from the Argentine Integrated Health Reporting System for all persons with suspected and RT-PCR-confirmed diagnosis of COVID-19 between 31 January and 14 July 2020.
    Outcomes: To estimate the effects of living in a slum on the standardised incidence rate of COVID-19, corrected Poisson regression models were used. Additionally, the impact of socioeconomic status was performed using an ecological analysis at the community level.
    Results: A total of 114 052 people were tested for symptoms related with COVID-19. Of these, 39 039 (34.2%) were RT-PCR positive. The incidence rates for COVID-19 towards the end of the 20th week were 160 (155 to 165) per 100 000 people among the inhabitants who did not reside in the slums (n=2 841 997) and 708 (674 to 642) among slums dwellers (n=233 749). Compared with the better-off socioeconomic quintile (1.00), there was a linear gradient on incidence rates: 1.36 (1.25 to 1.46), 1.61 (1.49 to 1.74), 1.86 (1.72 to 2.01), 2.94 (2.74 to 3.16) from Q2 to Q5, respectively. Slum dwellers were associated with an incidence rate of 14.3 (13.4 to 15.4).
    Conclusions: The distribution of the epidemic is socially conditioned. Slum dwellers are at a much higher risk than the rest of the community. Slum dwellers should not be considered just another risk category but an entirely different reality that requires policies tailored to their needs.

    Abstract Objectives: To evaluate whether a single high dose of oral cholecalciferol improves the respiratory outcomes as compared with placebo among adults COVID-19 patients at moderate risk of clinical complications.
    Trial design: The CARED trial is an investigator-initiated, multicentre, randomized, parallel, two-arm, sequential, double-blind and placebo-controlled clinical trial. It was planned as a pragmatic trial since the inclusion criteria are broad and the study procedures are as simple as possible, in order to be implemented in the routine clinical practice in general wards in the pandemic setting and a middle-income country context. The sequential design involves two stages. The first stage will assess the effects of vitamin D supplementation on blood oxygenation (physiological effects). The second stage will assess the effects on clinical outcomes.
    Participants: Participants of either gender admitted to general adult wards in 21 hospital sites located in four provinces of Argentina are invited to participate in the study if they meet the following inclusion criteria and none of the exclusion criteria: Inclusion criteria SARS-CoV-2 confirmed infection by RT-PCR; Hospital admission at least 24 hours before; Expected hospitalization in the same site ≥24 hours; Oxygen saturation ≥90% (measured by pulse oximetry) breathing ambient air; Age ≥45 years or at least one of the following conditions: ○ Hypertension; ○ Diabetes; ○ At least moderate COPD or asthma; ○ Cardiovascular disease (history of myocardial infarction, percutaneous transluminal coronary angioplasty, coronary artery bypass grafting or valve replacement surgery); ○ Body mass index ≥30; Willingness to sign informed consent (online supplementary material 1 and 2).
    Exclusion criteria: Age <18 years; Women in childbearing age; >= 72 hs since current admission; Requirement for a high dose of oxygen (>5 litres/minute) or mechanical ventilation (non-invasive or invasive); History of chronic kidney disease requiring haemodialysis or chronic liver failure; Inability for oral intake. Chronic supplementation with pharmacological vitamin D; Current treatment with anticonvulsants; History of: ○ Sarcoidosis; ○ Malabsorption syndrome; ○ Known hypercalcemia or serum calcium >10.5 mg/dL; Life expectancy <6 months; Known allergy to study medication; Any condition at discretion of investigator impeding to understand the study and give informed consent.
    Intervention and comparator: The intervention consists in a single oral dose of 500.000 IU of commercially available cholecalciferol soft gel capsules (5 capsules of 100.000 IU) or matching placebo MAIN OUTCOMES: The primary outcome for the first stage is the change in the respiratory Sepsis-related Organ Failure Assessment (SOFAr) score between pre-treatment value and the worst value recorded during the first 7 seven days of hospitalization, the death or discharge, whichever occurs first. The SOFAr score measured as the ratio between the pulse oximetry saturation (SpO
    Randomisation: A computer-generated random sequence and the treatment assignment is performed through the web-based randomization module available in the electronic data capture system (Castor®). A randomization ratio 1:1, stratified and with permuted blocks was used. Stratification variables were diabetes (yes/no), age (≤60/>60 years) and the site.
    Blinding (masking): Double-blind was achieved by using placebo soft gel capsules with the same organoleptic properties as the active medication. Central management of the medication is carried out by a pharmacist in charge of packaging the study drug in unblinded fashion, who have no contact with on-site investigators. Medication is packaged in opaque white bottles, each containing five soft gel capsules of the active drug or matching placebo, corresponding to complete individual treatment. Treatment codes are kept under the pharmacist responsibility, and all researchers are unaware of them.
    Numbers to be randomised (sample size): The first stage is planned to include 200 patients (100 per group), the second stage is planned to include 1064 additional patients. The total sample size is 1264 patients.
    Trial status: Currently the protocol version is the number 1.4 (from October 13
    Trial registration: The study protocol is registered in ClinicalTrials.gov (identifier number NCT04411446 ) on June 2, 2020.
    Full protocol: The full protocol is attached as an additional file, accessible from the Trials website (Additional file 1). In the interest in expediting dissemination of this material, the familiar formatting has been eliminated; this Letter serves as a summary of the key elements of the full protocol. The study protocol has been reported in accordance with the Standard Protocol Items: Recommendations for Clinical Interventional Trials (SPIRIT) guidelines (Additional file 2).

    Abstract Background: Fractional flow reserve (FFR) has become a useful tool in the assessment of physiological significance of coronary artery stenosis (CAS), and Adenosine (ADE) is associated with a high incidence of transient side effects. Sodium nitroprusside (NPS) has been proposed as an alternative vasodilator agent. A meta-analysis of studies comparing ADE and NPS for FFR assessment in the same coronary lesions was performed.
    Methods: Authors searched for articles comparing NPS and ADE for FFR assessment in intermediate coronary lesions published through January 2018. The following keywords were used: 'fractional flow reserve' AND 'nitroprusside'. Data were summarized using weighted mean differences for paired data.
    Results: Seven studies were identified comprising 342 patients and 401 lesions. Four studies evaluated intravenous ADE and 3 studies intracoronary ADE administration. Weighted means FFR values obtained with ADE and NPS were 0.8411 and 0.8445, respectively (weighted mean difference: 0.00, 95% confidence interval (CI) -0.01 to 0.01, p = 0,548). Adverse events were significantly reduced with IC NPS (RR = 0.08, 95%CI 0.02-0.30, P < 0.0001).
    Conclusions: NPS produces similar FFR measurements compared to ADE with a significant reduction in adverse effects. These results may support its use as a suitable alternative to ADE for FFR assessment.
