The impact of outdoor pollution and extreme temperatures on asthma-related outcomes: A systematic review for the EAACI guidelines on environmental science for allergic diseases and asthma.

Air pollution is one of the biggest environmental threats for asthma. Its impact is augmented by climate change. To inform the recommendations of the EAACI Guidelines on the environmental science for allergic diseases and asthma, a systematic review (SR) evaluated the impact on asthma-related outcomes of short-term exposure to outdoor air pollutants (PM2.5, PM10, NO2, SO2, O3, and CO), heavy traffic, outdoor pesticides, and extreme temperatures. Additionally, the SR evaluated the impact of the efficacy of interventions reducing outdoor pollutants. The risk of bias was assessed using ROBINS-E tools and the certainty of the evidence by using GRADE. Short-term exposure to PM2.5, PM10, and NO2 probably increases the risk of asthma-related hospital admissions (HA) and emergency department (ED) visits (moderate certainty evidence). Exposure to heavy traffic may increase HA and deteriorate asthma control (low certainty evidence). Interventions reducing outdoor pollutants may reduce asthma exacerbations (low to very low certainty evidence). Exposure to fumigants may increase the risk of new-onset asthma in agricultural workers, while exposure to 1,3-dichloropropene may increase the risk of asthma-related ED visits (low certainty evidence). Heatwaves and cold spells may increase the risk of asthma-related ED visits and HA and asthma mortality (low certainty evidence).

The impact of indoor pollution on asthma-related outcomes: A systematic review for the EAACI guidelines on environmental science for allergic diseases and asthma.

Systematic review using GRADE of the impact of exposure to volatile organic compounds (VOCs), cleaning agents, mould/damp, pesticides on the risk of (i) new-onset asthma (incidence) and (ii) adverse asthma-related outcomes (impact). MEDLINE, EMBASE and Web of Science were searched for indoor pollutant exposure studies reporting on new-onset asthma and critical and important asthma-related outcomes. Ninety four studies were included: 11 for VOCs (7 for incidenceand 4 for impact), 25 for cleaning agents (7 for incidenceand 8 for impact), 48 for damp/mould (26 for incidence and 22 for impact) and 10 for pesticides (8 for incidence and 2 for impact). Exposure to damp/mould increases the risk of new-onset wheeze (moderate certainty evidence). Exposure to cleaning agents may be associated with a higher risk of new-onset asthma and with asthma severity (low level of certainty). Exposure to pesticides and VOCs may increase the risk of new-onset asthma (very low certainty evidence). The impact on asthma-related outcomes of all major indoor pollutants is uncertain. As the level of certainty is low or very low for most of the available evidence on the impact of indoor pollutants on asthma-related outcomes more rigorous research in the field is warranted.

Self-perceived competence in managing obstetric emergencies among recently graduated physicians from Lima, Peru.

OBJECTIVE: This study aimed to examine the self-perception of competencies in obstetric emergencies among recently graduated physicians from universities in Lima, Peru; and to identify its associated factors. METHODS: An analytical study was conducted, with the study population comprising newly graduated doctors who attended the "VI SERUMS National Convention" in 2017. We used Poisson regressions to assess the factors associated with the self-perception of competencies in obstetric emergencies, calculating prevalence ratios (PR) and their 95% confidence intervals (95% CI). RESULTS: We analyzed a population of 463 newly graduated physicians (mean age: 25.9 years), of which 33.3% reported feeling competent in obstetric emergencies. In the adjusted analyses, we found that having a previous health career (PR: 1.77, 95% CI: 1.12-2.81), having completed the internship in EsSalud hospitals (PR: 1.48, 95% CI: 1.31-1.68), and completing a university externship (PR: 1.62, 95% CI: 1.34-1.96) were associated with a higher prevalence of self-perceived competence in obstetric emergencies. CONCLUSION: Our findings suggest that certain academic factors, such as completing an externship and internship in specific hospital settings, may enhance the competencies or competence self-perception of recently graduated physicians in obstetric emergencies. Further studies are needed to confirm these results and identify other factors that may impact physicians' competencies in this field.

Vitamin E supplementation improves testosterone, glucose- and lipid-related metabolism in women with polycystic ovary syndrome: a meta-analysis of randomized clinical trials.

AIM: This systematic review and meta-analysis assessed the effect of vitamin E supplementation on testosterone, glucose, lipid profile, pregnancy rate, hirsutism, and body mass index (BMI) in women with polycystic ovary syndrome (PCOS). METHODS: A multi-database search was performed from inception to January 2022 for randomized controlled trials (RCTs) reporting the effects of vitamin E supplementation with or without another nutritional supplement on women with PCOS. A random-effects model was used to obtain mean differences (MDs) and its 95% confidence intervals (95%CI). Evidence certainty was assessed with GRADE methodology. RESULTS: We meta-analyzed eight RCTs reporting vitamin E supplementation alone or combined with other individual substances like omega-3, vitamin D3, or magnesium oxide in adult women ≤40 years old with PCOS. Vitamin E supplementation reduced fasting glucose (MD: -1.92 mg/dL, 95%CI: -3.80 to -0.05), fasting insulin (MD: -2.24 µIU/mL, 95%CI: -3.34 to -1.14), HOMA-IR (MD: -0.42, 95%CI: -0.65 to -0.19), total cholesterol (MD: -18.12 mg/dL, 95%CI: -34.37 to -1.86), LDL-cholesterol (MD: -15.92 mg/dL, 95%CI: -29.93 to -1.90), triglycerides (MD: -20.95 mg/dL, 95%CI: -37.31 to -4.58), total testosterone (MD: -0.42 ng/mL, 95%CI: -0.55 to -0.29), and increased sex hormone-binding globulin (MD: 7.44 nmol/L, 95%CI: 2.68 to 12.20). However, it had no impact on female sex hormones, HDL-cholesterol, BMI, and hirsutism. Two RCTs assessed pregnancy and implantation rates with inconsistent results. The certainty of the evidence was very low to moderate. CONCLUSION: Vitamin E supplementation improves glucose, lipid, and androgenic-related biomarkers in women with PCOS.

Systematic review of warfarin-induced skin necrosis case reports and secondary analysis of factors associated with mortality.

OBJECTIVE: Warfarin-induced skin necrosis (WSN) is a rare (0.0.1%-0.1%) and severe adverse reaction. The clinical characteristics of this reaction and its mortality rate have not been explored in a large population. Therefore, we present the case of a Peruvian patient who developed WSN and perform a systematic review of case reports of WSN. METHODS: A systematic search was performed using the Pubmed/Medline, Scopus, Web of Science and Embase databases. Patient clinical data were collected and extracted from every case report. Furthermore, we analysed the factors associated with mortality because of WSN using the Poisson regression model with robust variations, obtaining risk ratios (RR) and their respective confidence intervals (95% CI). RESULTS: We identified 90 case reports that included a total of 111 patients with WSN (mean age 52.5 years), 20.72% of whom died of complications because of WSN. Being male (RR: 2.87; 95% CI 1.21-6.83) and having three or more affected regions (RR: 6.81; 95% CI 2.62-17.74) were associated with an increased risk of death caused by WSN. CONCLUSION: This systematic review identified 90 case reports of WSN with three or more affected body regions. Male sex was associated with an increased risk of death. Further studies are needed to analyse and confirm these results.

Factors associated with the consumption of chlorine dioxide to prevent and treat COVID-19 in the Peruvian population: a cross-sectional study.

BACKGROUND: Chlorine dioxide has been promoted as an alternative for the prevention and treatment of COVID-19, especially in Peru, despite the lack of evidence to support its efficacy. This study aimed to evaluate the factors associated with chlorine dioxide consumption in the Peruvian population. METHODS: Analytical cross-sectional study. An adult Peruvian population was evaluated where chlorine dioxide consumption was divided into two groups according to the purpose of use: as prevention (individuals without COVID-19 history) and as treatment (individuals with COVID-19 history). The associated factors in each group were evaluated using Poisson regressions with the bootstrapping resampling method. RESULTS: Of 3610 participants included, 3213 reported no history of COVID-19, and 397 had been infected. The prevalence of chlorine dioxide consumption to prevent or treat COVID-19 was 8 and 16%, respectively. Factors either positively or negatively associated with chlorine dioxide consumption for prevention were male sex (aPR: 1.36; 95% CI: 1.09-1.71), being an adult or older adult (aPR: 0.54; 95% CI: 0.35-0.82), having a health sciences student within the family unit (aPR: 1.38; 95% CI: 1.02-1.87), using medical information as the main source of information of COVID-19 (aPR: 0.57; 95% CI: 0.40-0.80), having comorbidities for COVID-19 (aPR: 1.36; 95% CI: 1.01-1.82), considering COVID-19 dangerous and deadly (aPR: 0.57; 95% CI: 0.45-0.74), using medications (aPR: 1.59; 95% CI: 1.25-2.06) and plants to prevent COVID-19 (aPR: 1.69; 95% CI: 1.21-2.36), considering chlorine dioxide ineffective (aPR: 0.18; 95% CI: 0.18-0.24), and being uninformed of its efficacy (aPR: 0.21; 95% CI: 0.16-0.28). In addition, factors associated with chlorine dioxide consumption for treatment were considering COVID-19 dangerous and deadly (aPR: 0.56; 95% CI: 0.33-0.96), considering chlorine dioxide ineffective (aPR: 0.22; 95% CI: 0.12-0.42), and being uninformed of its efficacy (aPR: 0.15; 95% CI: 0.07-0.32). CONCLUSIONS: The prevalence of chlorine dioxide consumption to treat COVID-19 was higher than prevent. It is important to apply information strategies, prioritizing population groups with certain characteristics that are associated with a higher consumption pattern.

[Clinical practice guidelines for the diagnosis and management chronic infection of hepatitis viral C of the Peruvian Health Social Security (EsSalud)]. / Guía de práctica clínica para el diagnóstico y tratamiento de la infección crónica por el virus de hepatitis C en el Seguro Social de Salud del Perú (EsSalud).

INTRODUCTION: This article summarizes the clinical practice guidelines (CPG) for the diagnosis and treatment of chronic infection of hepatitis viral C of the Peruvian Health Social Security (EsSalud). OBJECTIVE: To provide clinical recommendations based on evidence for the diagnosis and treatment of chronic infection of hepatitis viral C in EsSalud. METHODS: A guideline development group (GDG) was established, including medical specialists and methodologists. The GDG formulated 4 clinical questions to be answered in this CPG. Systematic searches of systematic reviews and primary studies (when pertinent) were conducted in PubMed, and Central (Cochrane) during 2019. The evidence was selected to answer each of the clinical questions. The accuracy of the evidence was evaluated using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) methodology. In periodic work meetings, the GEG used the GRADE methodology to review the evidence and formulate the recommendations, the points of good clinical practice and the treatment flowchart. Finally, the CPG was approved with Resolution No. 151-IETSIESSALUD-2019. RESULTS: The present CPG addressed 4 clinical questions of four topics: screening, diagnosis, staging and treatment. Based on these questions, 13 recommendations (8 strong recommendations and 5 weak recommendations), 27 points of good clinical practice, and 1 flowchart were formulated. CONCLUSION: This paper summarizes the methodology and evidencebased conclusions from the CPG for for the diagnosis and treatment of chronic infection of hepatitis viral C of the EsSalud.

Factors associated with non-treatment for long-term illness among incarcerated individuals.

PURPOSE: The prison population is seldom studied and often overlooked in many countries despite their vulnerability to long-term illness. This study aims to explore the factors associated with the non-treatment for long-term illnesses among incarcerated individuals. DESIGN/METHODOLOGY/APPROACH: This study is a cross-sectional analysis. The authors conducted a secondary data analysis using information collected in the Peruvian census of incarcerated individuals. The study population consisted of incarcerated individuals diagnosed with a long-term illness. To evaluate the factors associated with non-treatment, the authors used a Poisson regression model. FINDINGS: The authors included 12,512 incarcerated individuals (age: 40.9 ± 13.1 years), and 39% of them did not receive treatment for their long-term illness. The authors observed that non-treatment was statistically associated with gender, age, having children, use of the Spanish language, sexual identity, judicial situation, penitentiary location, discrimination inside the penitentiary and health insurance before incarceration. However, only having children (prevalence ratio [PR]: 1.11, confidence interval [CI]95% 1.03-1.19), using the Spanish language (PR: 1.15, CI95%: 1.01-1.31), being in a penitentiary not in Lima (PR: 1.11, CI95%: 1.06-1.17) and perceiving discrimination inside the penitentiary (PR: 1.12, CI95% 1.06-1.18) increased the prevalence of non-treatment. ORIGINALITY/VALUE: Identifying the factors associated with non-treatment will allow us to implement measures for prioritizing groups and developing strategies for the evaluation, close follow-up of their health and management of comorbidities.

Factors associated with the consumption of medicinal plants for the prevention of COVID-19 in peruvian population: a cross-sectional study. / Factores asociados con el consumo de plantas medicinales para la prevención de COVID-19 en población peruana: un estudio transversal.

OBJECTIVES.: Motivation for the study. No study conclusively recommends the use of medicinal plants to treat COVID-19 symptoms, and their indiscriminate use may present health risks. Main findings. Sixty percent of participants consumed medicinal plants to prevent COVID-19. This was particularly true for those living in the Peruvian highlands and individuals with family members diagnosed or deceased from COVID-19, who perceive a higher risk of infection and use medications or chlorine dioxide as preventive measures. Implications. Communication strategies emphasizing validated preventive practices and educating about the risks of consuming medicinal plants should be tailored to the predominant characteristics of the consumer. Determine the factors associated with the consumption of medicinal plants as a preventive measure against COVID-19 in the Peruvian population. MATERIALS AND METHODS.: A population over 18 years of age, living in Peru and without a history of COVID-19 disease, was evaluated. The factors associated with the consumption of medicinal plants were evaluated using a Poisson regression model with robust variances. RESULTS.: Of the 3231 participants included, 84.6% were young adults (18-29 years old), 62.7% were women, and 59.7% consumed a medicinal plant to prevent COVID-19 infection. The factors associated with the consumption of medicinal plants to prevent COVID-19 infection were residing in the Peruvian highlands, having had a family member diagnosed with COVID-19, having had a family member die from COVID-19, considering their family to be at increased risk of infection, having used medications or chlorine dioxide to prevent COVID-19, having medical information as the main source of information about COVID-19, thinking that medicinal plants are effective in preventing COVID-19 disease, or not being informed about their effectiveness. CONCLUSION.: Sixty percent of the participants reported having consumed a medicinal plant to prevent COVID-19. Authorities must apply communication strategies about the implications of consuming medicinal plants, prioritizing population groups with higher consumption patterns.

OBJETIVOS: Motivación para realizar el estudio. Ningún estudio recomienda de manera concluyente el uso de plantas medicinales para tratar los síntomas de la COVID-19, y su uso indiscriminado puede presentar riesgos para la salud. Principales hallazgos. El 60% de los participantes utilizó plantas medicinales para la prevención de la COVID-19. Especialmente aquellos de la sierra peruana y personas con familiares diagnosticados o fallecidos por COVID-19, que perciben mayores riesgos de contagio y utilizan medicamentos o dióxido de cloro como medidas preventivas. Implicancias. Las estrategias de comunicación esenciales para las prácticas preventivas validadas y la educación sobre los riesgos del consumo de plantas medicinales deben adaptarse a las características predominantes del consumidor. Determinar los factores asociados al consumo de plantas medicinales como prevención de la COVID-19 en la población peruana. MATERIALES Y MÉTODOS.: Se evaluó población mayor de 18 años, residentes en Perú y sin antecedentes de enfermedad por COVID-19. Los factores asociados al consumo de plantas medicinales se evaluaron mediante un modelo de regresión de Poisson con varianzas robustas. RESULTADOS.: De 3231 participantes incluidos, el 84,6% eran jóvenes (18-29 años), el 62,7% eran mujeres y el 59,7% consumía alguna planta medicinal para prevenir la COVID-19. Los factores asociados al consumo de plantas medicinales para prevenir el contagio de COVID-19 fueron residir en la sierra peruana, haber tenido un familiar diagnosticado con COVID-19, haber tenido un familiar fallecido por COVID-19, considerar que su familia se encuentra en mayor riesgo de infección, haber usado medicamentos o dióxido de cloro para prevenir la COVID-19, tener información médica como principal fuente de información sobre la COVID-19, pensar que las plantas medicinales son efectivas para prevenir la enfermedad COVID-19 o no estar informado sobre su eficacia. CONCLUSIÓN: . El 60% de los participantes reportó haber consumido alguna planta medicinal para prevenir la COVID-19. Es importante que las autoridades apliquen estrategias de comunicación sobre lo que implica el consumo de plantas medicinales, priorizando los grupos poblacionales que tienen mayores patrones de consumo.

Prediction models of COVID-19 fatality in nine Peruvian provinces: A secondary analysis of the national epidemiological surveillance system.

There are initiatives to promote the creation of predictive COVID-19 fatality models to assist decision-makers. The study aimed to develop prediction models for COVID-19 fatality using population data recorded in the national epidemiological surveillance system of Peru. A retrospective cohort study was conducted (March to September of 2020). The study population consisted of confirmed COVID-19 cases reported in the surveillance system of nine provinces of Lima, Peru. A random sample of 80% of the study population was selected, and four prediction models were constructed using four different strategies to select variables: 1) previously analyzed variables in machine learning models; 2) based on the LASSO method; 3) based on significance; and 4) based on a post-hoc approach with variables consistently included in the three previous strategies. The internal validation was performed with the remaining 20% of the population. Four prediction models were successfully created and validate using data from 22,098 cases. All models performed adequately and similarly; however, we selected models derived from strategy 1 (AUC 0.89, CI95% 0.87-0.91) and strategy 4 (AUC 0.88, CI95% 0.86-0.90). The performance of both models was robust in validation and sensitivity analyses. This study offers insights into estimating COVID-19 fatality within the Peruvian population. Our findings contribute to the advancement of prediction models for COVID-19 fatality and may aid in identifying individuals at increased risk, enabling targeted interventions to mitigate the disease. Future studies should confirm the performance and validate the usefulness of the models described here under real-world conditions and settings.

An appraisal of the methodology and quality of evidence of systematic reviews on the efficacy of prone positional ventilation in adult patients with acute respiratory distress syndrome: an umbrella review.

The objective of the study was to evaluate all available systematic reviews on the use of prone positional ventilation in adult patients with acute respiratory distress syndrome (ARDS). An umbrella review on the efficacy of prone positional ventilation in adult patients ventilation in adult patients with acute respiratory distress syndrome was conducted. We performed a systematic search in the database of Medline (Pubmed), Scopus, Cochrane Library, Web of Science, and Epistemonikos. The ROBIS tools and GRADE methodology were used to assess the risk of bias and certainty of evidence. We estimated the necessary number of patients to be treated to have benefit. For the synthesis of the result, we selected the review with the lowest risk of bias. Sixteen systematic reviews including 64 randomized clinical trials and evaluating the effect of prone positional ventilation, with or without other ventilation strategies were included. Aoyama 2019 observed prone positioning, without complementary ventilation strategies, leading to a reduction in the 28-day mortality only when compared to high-frequency oscillatory ventilation (RR 0.61; 95% CI 0.39-0.95) and lung-protective ventilation in the supine position (RR 0.69; 95% CI 0.48-0.98), with an ARR of 9.32% and 14.94%, an NNTB of 5.89 and 8.04, and a low and moderate certainty of evidence, respectively. Most reviews had severe methodological flaws that led to results with very low certainty of evidence. The review with the lowest risk of bias presented results in favor of prone positional ventilation compared with high-frequency oscillatory ventilation and lung-protective ventilation. There is a need to update the available reviews to obtain more accurate results.

Association between self-reported evidence-based medicine competencies and prescribing of drugs without scientific evidence against mild COVID-19 among recently graduated physicians in Peru.

Objective: To evaluate the association between self-rated evidence-based medicine (EBM) competencies and the prescription of drugs without scientific evidence against mild COVID-19 (present with any of the signs and symptoms of COVID-19 but who do not have shortness of breath, dyspnea, or abnormal chest imaging) among recently graduated physicians in Peru. Methods: We conducted an analytical cross-sectional study where we evaluated a non-probability sample of recently graduated physicians during June and July 2021 (end of second wave of COVID-19 in Peru). Self-rated EBM competencies were assessed by four domains (formulation of a clinical question, search, analysis, and application) using a Likert scale with scores from zero to four ("Very inadequate" = 0, to "Very Adequate" = 4), it was considered as "Adequate" if the score was three or four. In addition, the variable "General competence on EBM" was rated as "Adequate" if in all domains evaluated it presented an adequate self-rating. For the outcome, drug prescription, we considered the use of ivermectin, azithromycin, other antibiotics, hydroxychloroquine, dexamethasone, and anticoagulants (drugs with no efficacy demonstrated for patients with mild COVID-19). To assess the association, we used Poisson regression models with robust variances and obtaining crude (cPR) and adjusted (aPR) prevalence ratios with their 95% confidence intervals (95%CI). Results: Of a total of 239 physicians included 70.7% prescribed at least one drug without scientific evidence. A total of 51.1% reported adequate ratings in all evaluated domains of EBM. Self-rating the "Clinical Question Formulation" competency as adequate was associated with a lower frequency of prescribing medications for mild COVID-19 (aPR: 0.93; 95% CI: 0.91-0.95). While self-rating as adequate the competency of "Identify possible implications of investigations" was associated with an increase in the prescription of such drugs (aPR: 1.14; 95% CI: 1.09-1.20). Additionally, self-rating all domains as adequate were associated with less prescription (aPR: 0.93; 95% CI: 0.90-0.96). Conclusion: Seven out of ten recently graduated physicians prescribed some type of medication without scientific evidence to treat patients with mild COVID-19. Having adequate self-perceived EBM competencies was associated with a lower frequency of prescribing medications without scientific evidence to manage patients with mild COVID-19.

Latin America and the Caribbean Code Against cancer 1st edition: Environment, occupation, and cancer.

Within the framework of the Latin America and Caribbean region (LAC) Code Against Cancer 1st edition, the current work presents recommendations to reduce exposure to environmental and occupational carcinogenic agents relevant for LAC. Using the methodology established by the International Agency for Research on Cancer (IARC) in the World Code Against Cancer Framework and experience from developing the European Code Against Cancer 4th edition, a working group of LAC cancer-prevention experts reviewed the list of Group I IARC carcinogenic agents, identified prevalent environmental and occupational exposures in the region, and proposed evidence-based cancer prevention recommendations suited to the epidemiological, socioeconomic, and cultural conditions of LAC countries. Two sets of recommendations were drafted: those targeting the general public and a second set for policymakers. Outdoor and indoor air pollution, ultra-violet radiation and occupational exposures to silica dust, asbestos, benzene, diesel, and welding fumes were identified as prevalent carcinogens in LAC and as agents that could be reduced or eliminated to prevent cancers. Recommendations for additional risk factors were not included due to insufficient data of their attributable burden in LAC (sunbeds, radon, aflatoxin), or lack of a clear preventive action to be taken by the individual (arsenic in drinking water, medical radiation), or lack of evidence of carcinogenicity effect (bisphenol A, phthalates, and pesticides). A broad consensus was reached on environmental and occupational carcinogenic exposures present throughout the LAC region and on individual-level and public policy-level recommendations to reduce or eliminate these exposures. Key educational content for the dissemination of these recommendations was also developed as part of LAC Code Against Cancer 1st Edition.

Methodological appraisal of the evidence about efficacy of metabolic surgery in adults with non-morbid obesity and hypertension: An overview of systematic reviews.

BACKGROUND: Nowadays, the high morbimortality of obesity is mainly related to diabetes, cancer, and hypertension. It is reported that obesity in patients with hypertension can lead to resistance to pressure reduction through pharmacological therapy and lifestyle changes, so bariatric surgery emerges as a proposed treatment for obesity. METHODS: We performed an umbrella review that included systematic reviews of clinical trials that evaluated patients with hypertension and non-morbid obesity. The quality and certainty of the evidence was evaluated with the AMSTAR-II and GRADE tools. RESULTS: 677 systematic reviews were identified, of which only three were included for analysis. We considered the outcomes addressed by the reviews on hypertension, identifying that 5 RCTs evaluated pressure reduction at 1 year of follow-up and 5 RCTs at more than 1 year, 5 RCTs evaluated hypertension rate, 6 RCTs analyzed changes in systolic pressure and 5 RCTs changes in diastolic pressure. Likewise, when assessing the methodological quality, it was concluded that the three reviews have critically low quality. CONCLUSIONS: We found only three systematic reviews that evaluated the topic with critically low methodological quality. They reported results in favor of metabolic surgery, but with very low certainty of evidence.

Scientific production in heart failure in Peru: a bibliometric study.

OBJECTIVE: To analyze the Peruvian scientific production on Heart Failure (HF) in the period 2000-2020. METHODS: We performed an observational bibliometric study, in the Scopus and Scielo database, of documents published on heart failure by an author with Peruvian affiliation, between the years 2000 and 2020. We describe variables of scientific production, number of annual publications, documents, characteristics of the publications, and institutions. The collaborative networks were analyzed by building a network of nodes using the VOSViewer v1.6.5 software. RESULTS: A 236 publications were found in Scopus and 55 in Scielo. The largest number of documents were original articles followed by review articles. The journal "The Lancet" and "Revista Peruana de Medicina Experimental y Salud Pública" were those that had the highest number of publications. Thirty-one countries were registered that had at least 5 documents published with an author from Peru. Scientific collaboration was mainly with the United States and at the regional level with Argentina. 55 documents were published with only Peruvian authors. CONCLUSION: The scientific production in HF by Peruvian authors is in exponential growth. And the Universidad Peruana Cayetano Heredia/CRÓNICAS is the Peruvian institution with the most publications on it.

Factors associated with prevention practices against COVID-19 in the Peruvian population: Disparities between rural and urban areas.

OBJECTIVE: To determine the factors associated with prevention practices against COVID-19 in the Peruvian population according to rural vs. urban locations. METHODS: Analytical cross-sectional study, secondary analysis based on a previously collected database. A sample of individuals over 18 years of age, residing in Peru and with no history of COVID-19was evaluated. Factors associated with prevention practices were evaluated using Poisson regressions with variance adjustment by region cluster and stratified by rurality. RESULTS: Of 3231 participants included, 2741 (84.8%) were from urban areas and 490 (15.2%) from rural areas. The frequency of good prevention practices against COVID-19 was 27.8% in our total sample. In urban areas the frequency of good prevention practices was 28.8% and in rural areas it was 22.5%. Factors associated with prevention practices against COVID-19 in both urban and rural areas were male sex (urban: aPR 0.64, 95%CI 0.55-0.75; rural: aPR 0.66, 95%CI 0.54-0.80) and self-considering adequately carrying out prevention practices (urban: aPR 2.48, 95%CI 2.13-2.89; rural: aPR 2.70, 95%CI 2.27-3.19). CONCLUSION: The frequency of good prevention practices against COVID-19 was less than 30% in both urban and rural areas. There are differences in the factors associated with good preventive practice against COVID-19. Only sex and considering that preventive measures were adequately carried out were associated with good prevention practices in both areas. In view of this, prevention measures should be promoted taking into account cultural principles and considering geographical location in the face of present and future outbreaks or pandemics.

Factors associated with the intention to participate in COVID-19 vaccine clinical trials: A cross-sectional study in Peru.

OBJECTIVE: To evaluate the factors associated with the intention to participate in COVID-19 vaccine clinical trials in the Peruvian population. METHODS: Cross-sectional study and secondary analysis of a database that involved Peruvian population during September 2020. The Poisson regression model was used to estimate the associated factors. RESULTS: Data from 3231 individuals were analyzed, 44.1% of whom intended to participate in COVID-19 vaccine clinical trials. Factors associated with the outcome were being male (RPa: 1.25; 95% CI: 1.15-1.35), being from the highlands region (RPa: 1.18; 95% CI: 1.09-1.28) or jungle (RPa: 1.30; 95% CI: 1.15-1.47), having a relative that is a healthcare professional (PRa: 1.16; 95% CI: 1.06-1.28), using a medical source of information (PRa: 1.28; 95% CI: 1.17-1.41), and trusting in the possible effectiveness of vaccines (PRa: 1.40; 95% CI: 1.29-1.51). The main reason for not participating in the trial was the possibility of developing side effects (69.80%). CONCLUSION: There is an urgent need to generate a perception of safety in COVID-19 vaccine clinical trials, to increase the population's intention to participate in these studies, and to provide evidence-based information about the vaccine.

Factors Associated With Drug Consumption Without Scientific Evidence in Patients With Mild COVID-19 in Peru.

OBJECTIVE: This study aimed to evaluate the factors associated with the consumption of drugs without scientific evidence in patients with mild COVID-19 infection in Peru. METHODS: An analytical cross-sectional study was carried out including 372 adult patients with a history of mild COVID-19 disease. Factors associated with drug consumption were evaluated by Poisson regressions with robust variance adjustment using the bootstrapping resampling method. RESULTS: Seventy-two percent consumed some medication without scientific evidence, with antibiotics (71%) and ivermectin for human use (68%) being the most commonly used. Factors associated with the consumption of drugs to treat mild COVID-19 infection were thinking that the drugs are not effective (adjusted prevalence ratio, 0.55; 95% confidence interval, 0.41-0.74) and not being informed about the efficacy of the drugs (adjusted prevalence ratio, 0.48; 95% confidence interval, 0.36-0.65). CONCLUSIONS: Education of the population seems to be the main factor that increases the consumption of drugs without scientific evidence in the Peruvian population to treat mild COVID-19.
