RESUMO

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.

RESUMO

OBJECTIVES: This systematic review aimed to assess the prevalence and incidence of diabetic retinopathy in patients with diabetes of Latin America and the Caribbean. METHODS: We searched Web of Science (WoS)/Core Collection, WoS/MEDLINE, WoS/Scielo, Scopus, PubMed/Medline and Embase databases until January 16, 2023. We meta-analyzed prevalences according to type 1 diabetes mellitus (T1DM) and type 2 diabetes mellitus (T2DM). RESULTS: Forty-three prevalence studies (47 585 participants) and one incidence study (436 participants) were included. The overall prevalence of retinopathy in patients with T1DM was 40.6% (95% CI: 34.7 to 46.6; I2: 92.1%) and in T2DM was 37.3% (95% CI: 31.0 to 43.8; I2: 97.7), but the evidence is very uncertain (very low certainty of evidence). In meta-regression, we found that age (T1DM) and time in diabetes (T2DM) were factors associated with the prevalence. On the other hand, one study found a cumulative incidence of diabetic retinopathy of 39.6% at 9 years of follow-up. CONCLUSIONS: Two out of five patients with T1DM or T2DM may present diabetic retinopathy in Latin America and the Caribbean, but the evidence is very uncertain. This is a major public health problem, and policies and strategies for early detection and opportunely treatment should be proposed.

RESUMO

Background: Invasive management of stable coronary artery disease is still a controversial topic. The purpose of this umbrella review was to synthesize systematic reviews (SRs) that evaluate the benefits and harms of percutaneous coronary intervention (PCI) versus optimal medical therapy (OMT) in patients with stable coronary artery disease. Methods: We systematically searched PubMed/MEDLINE, Embase, and CENTRAL from 2018 to August 7, 2022. We included SRs with meta-analyses of randomized controlled trials (RCTs) that evaluated the question of interest. We assessed the methodological quality of the SRs with the AMSTAR-2 tool. We summarized the results of the outcomes for each SR. We calculated the degree of overlap of the RCTs included in the SRs using the corrected covered area (CCA). Results: We found 10 SRs with meta-analyses. The SRs included 3 to 15 RCTs. The degree of overlap among the SRs was very high (CCA > 15%). No SR evaluated the certainty of the evidence using the GRADE system and 9 out of 10 had critically low methodological quality. The SRs reported heterogeneous results for the outcomes of all-cause mortality, myocardial infarction, revascularization, and angina. On the other hand, for the outcomes of cardiovascular mortality and stroke, all SRs agreed that there were no differences between PCI and OMT alone. Conclusions: We found 10 SRs on the use of PCI compared to OMT alone for patients with stable coronary artery disease. However, none had high methodological quality, none evaluated the certainty of the evidence using the GRADE approach, and the results were inconsistent for several outcomes. This variability in evidence may result in divergent clinical decisions for the management of stable coronary artery disease among healthcare professionals. It is necessary to perform a high-quality SR using the GRADE approach to clarify the balance of benefits and harms of PCI.

RESUMO

Objective: This scoping review aimed to describe studies that evaluate the management of cryptococcal meningitis (CM) using cerebrospinal fluid (CSF) shunts, types of shunts used, and clinically relevant patient outcomes. Methods: We searched in the following databases: PubMed, Web of Science/Core collection, Embase, the Cochrane Library, and clinicaltrials.gov on 1 April 2022. We included two-arm and one-arm cohort studies that evaluated clinically relevant patient outcomes. Case reports were used to describe the type of CSF shunts used and the rationale behind its selection. The selection and extraction processes were independently performed by two authors. Results: This study included 20 cohort studies and 26 case reports. Only seven cohort studies compared two groups. Ventriculoperitoneal shunt was the most commonly used type of shunt (82.1%). The main indications for placing a shunt were persistently high opening pressure (57.1%) and persisting neurological symptoms or deterioration (54.3%). Cohort studies suggest that patients with shunt showed improvement in some outcomes such as neurological symptoms and hospital stay length. The most common shunt complications were post-operative fever (1-35.6%) and shunt obstruction (7-16%). Conclusion: CSF shunts may improve some clinically relevant outcomes in patients with CM, but the evidence is very uncertain.

RESUMO

PURPOSE: This review aimed to estimate the prevalence of computer vision syndrome (CVS) in the general population and subgroups. METHODS: A search was conducted in the following the databases: PubMed, SCOPUS, EMBASE, and Web of Science until February 13, 2023. We included studies that assessed the prevalence of CVS in any population. The Joanna Briggs Institute's critical appraisal tool was used to evaluate the methodological quality. A meta-analysis of the prevalence of CVS was done using a random-effects model, assessing the sources of heterogeneity using subgroup and meta-regression analyses. RESULTS: A total of 103 cross-sectional studies with 66 577 participants were included. The prevalence of CVS was 69.0% (95% CI: 62.3 to 75.3; I2: 99.7%), ranging from 12.1 to 97.3% across studies. Point prevalence was higher in women than in men (71.4 vs. 61.8%), university students (76.1%), Africa (71.2%), Asia (69.9%), contact lens wearers (73.1% vs. 63.8%) in studies conducted before the COVID-19 pandemic (72.8%), and in those that did not use the CVS-Q questionnaire (75.4%). In meta-regression, using the CVS-Q scale was associated with a lower prevalence of CVS. CONCLUSION: Seven out of ten people suffer from CVS. Preventive strategies and interventions are needed to decrease the prevalence of this condition which can affect productivity and quality of life. Future studies should standardize a definition of CVS.

RESUMO

BACKGROUND: Few epidemiologic studies have focused on the specific source of ambient air pollution and adverse health effects in early life. Here, we investigated whether air pollutants from different emission sources were associated with decreased birth anthropometry parameters and increased DNA adduct formation in mother-child pairs residing in the Mexico City Metropolitan Area (MCMA). METHODS: This cross-sectional study included 190 pregnant women recruited during their last trimester of pregnancy from two hospitals at MCMA, and a Modeling Emissions Inventory (MEI) to calculate exposure to ambient air pollutants from different emissions sources (area, point, mobile, and natural) for two geographical buffers 250 and 750 m radii around the participants households. RESULTS: Contaminants were positively correlated with umbilical cord blood (UCB) adducts, but not with maternal blood (MB) adducts. PM10 emissions (area and point sources, overall emissions), PM2.5 (point sources), volatile organic compounds (VOC), total organic compounds (TOC) from point sources were positively correlated with UCB adducts. Air pollutants emitted from natural sources were correlated with a decrease in MB and UCB adducts. PM10 and PM2.5 were correlated (p < 0.05) with a decrease in birth weight (BW), birth length (BL) and gestational age at term (GA). In multivariate analyses adjusted for potential confounders, PM10 was associated with an increase in UCB adducts. PM10 and PM2.5 from overall emissions were associated with a decrease in BW, BL and GA at term. IMPACT: Results suggested higher susceptibility of newborns compared to mothers to damage related to ambient air pollution. PMs are associated with birth anthropometry parameters and DNA damage in adjusted models, highlighting the need for more strict regulation of PM emissions.

RESUMO

El blastoma pulmonar es una neoplasia poco común y agresiva que se origina en el pulmón; está compuesto por tejido mesenquimal y epitelial inmaduro que imita la configuración pulmonar en etapas embrionarias. Tiene una baja incidencia y una alta tasa de mortalidad, con aproximadamente un 60 %. Este blastoma tiende a desarrollarse con mayor frecuencia entre la cuarta y quinta década de vida, siendo más prevalente en mujeres y generalmente asociado al tabaquismo. Se presenta el caso de una mujer de 23 años sin factores de riesgo conocidos, a quien se le diagnosticó incidentalmente un blastoma pulmonar primario. La paciente experimentaba dolor en la región costal izquierda, tos productiva, disnea y hemoptisis desde hace 30 días. Los hallazgos en las imágenes de rayos X y tomografías de tórax llevaron a la realización de una biopsia del pulmón izquierdo, que reveló fragmentos de tejido con una notable presencia de necrosis tumoral. Cinco días después, la paciente consultó nuevamente debido a un empeoramiento de los síntomas, incluyendo dolor torácico de tipo pleurítico. Se decidió realizar una lobectomía inferior izquierda, durante la cual se encontró un tumor sólido adherido a la pleura visceral, con masas tumorales en la pleura parietal. El estudio histopatológico final confirmó el diagnóstico de un tumor maligno de alto grado compatible con blastoma pulmonar. En conclusión, el blastoma pulmonar es una neoplasia rara que puede presentarse en diferentes etapas de la vida, aunque tiene mayor incidencia entre los 40 y 50 años. Es importante que los patólogos consideren esta enfermedad en sus diagnósticos diferenciales debido a los desafíos que implica su diagnóstico. Detectar el blastoma pulmonar en etapas tempranas es crucial para el tratamiento adecuado, aunque actualmente no se conocen marcadores predictivos confiables y el pronóstico de esta enfermedad es generalmente desfavorable.

Pulmonary blastoma is a rare and aggressive neoplasm that originates in the lung. It is composed of immature mesenchymal and epithelial tissue that mimics the embryonic configuration of the lung. It has a low incidence and a high mortality rate, of approximately 60%. Pulmonary blastoma tends to occur more frequently between the fourth and fifth decades of life, being more prevalent in women and generally associated with smoking. The case of a 23-year-old woman with no known risk factors is presented, who incidentally was diagnosed with a primary pulmonary blastoma. The patient experienced pain in the left costal region, productive cough, dyspnea, and hemoptysis for 30 days. Findings on X-ray and chest tomography led to a biopsy of the left lung, which revealed tissue fragments with significant tumor necrosis. Five days later, the patient consulted again due to worsened symptoms, including pleuritic chest pain. It was decided to perform a left lower lobectomy, during which a solid tumor attached to the visceral pleura with tumor masses in the parietal pleura was found. The final histopathological study confirmed the diagnosis of a high-grade malignant tumor compatible with pulmonary blastoma. In conclusion, pulmonary blastoma is a rare neoplasm that can occur at different stages of life, although it has a higher incidence between the ages of 40 and 50. Pathologists need to consider this disease in their differential diagnoses due to the challenges involved in its diagnosis. Detecting pulmonary blastoma at early stages is crucial for appropriate treatment, although currently there are no reliable predictive markers, and the prognosis of this disease is generally unfavorable.

RESUMO

Introduction: An association between weight status and migraine has been previously reported; however, this relationship has only been studied in adults, not in the paediatric population. Objective: To evaluate the association between weight status and migraine in the paediatric population. Methods: We searched PubMed/Medline, Scopus, Web of Science, Ovid Medline, and Embase using a cut-off date of May 2023. We included observational studies that evaluated the association between weight status (underweight, overweight, obese, and excess weight) and migraine in the paediatric population (children and adolescents). Normal weight was the comparator. The outcome was migraine (all types, episodic and chronic). We performed meta-analyses using a random-effects model to estimate the pooled effects for each outcome. Sensitivity analysis was performed based on study design and risk of bias (using the Newcastle-Ottawa Scale). Certainty of evidence was assessed using the GRADE approach. Results: Eight studies (6 cross-sectional, 1 case-control and 1 cohort) covering 16,556 patients were included. The overall certainty of evidence was very low for the association between overweight, obesity, and excess weight with migraine. In the sensitivity analysis, meta-analyses of studies with a low risk of bias found that the overweight population probably had an increased odds of migraine (OR: 1.70; 95% CI: 1.14 to 2.53; I2 = 32.3%, p = 0.224) and that excess weight may increase the odds of migraine (OR: 1.58; 95% CI: 1.06 to 2.35; I2 = 83.7%, p = 0.002). Additionally, cohort and case-control studies found that obesity probably increases the odds of migraine. No studies analysed the association between underweight and migraine. Conclusion: The associations between overweight, obesity, excess weight and migraine were uncertain, but studies with better methodological quality reported increased odds. Future longitudinal studies with proper confounding control are needed to disentangle their causal relationship. Systematic review registration: PROSPERO, identifier CRD42021271533.
