RESUMEN

BACKGROUND: In breast cancer screening programmes, women may have discussions with a healthcare provider to help them decide whether or not they wish to join the breast cancer screening programme. This process is called shared decision-making (SDM) and involves discussions and decisions based on the evidence and the person's values and preferences. SDM is becoming a recommended approach in clinical guidelines, extending beyond decision aids. However, the overall effect of SDM in women deciding to participate in breast cancer screening remains uncertain. OBJECTIVES: To assess the effect of SDM on women's satisfaction, confidence, and knowledge when deciding whether to participate in breast cancer screening. SEARCH METHODS: We searched the Cochrane Breast Cancer Group's Specialised Register, CENTRAL, MEDLINE, Embase, CINAHL, PsycINFO, ClinicalTrials.gov, and the World Health Organization International Clinical Trials Registry Platform on 8 August 2023. We also screened abstracts from two relevant conferences from 2020 to 2023. SELECTION CRITERIA: We included parallel randomised controlled trials (RCTs) and cluster-RCTs assessing interventions targeting various components of SDM. The focus was on supporting women aged 40 to 75 at average or above-average risk of breast cancer in their decision to participate in breast cancer screening. DATA COLLECTION AND ANALYSIS: Two review authors independently assessed studies for inclusion and conducted data extraction, risk of bias assessment, and GRADE assessment of the certainty of the evidence. Review outcomes included satisfaction with the decision-making process, confidence in the decision made, knowledge of all options, adherence to the chosen option, women's involvement in SDM, woman-clinician communication, and mental health. MAIN RESULTS: We identified 19 studies with 64,215 randomised women, mostly with an average to moderate risk of breast cancer. Two studies covered all aspects of SDM; six examined shortened forms of SDM involving communication on risks and personal values; and 11 focused on enhanced communication of risk without other SDM aspects. SDM involving all components compared to control The two eligible studies did not assess satisfaction with the SDM process or confidence in the decision. Based on a single study, SDM showed uncertain effects on participant knowledge regarding the age to start screening (risk ratio (RR) 1.18, 95% confidence interval (CI) 0.61 to 2.28; 133 women; very low certainty evidence) and frequency of testing (RR 0.84, 95% CI 0.68 to 1.04; 133 women; very low certainty evidence). Other review outcomes were not measured. Abbreviated forms of SDM with clarification of values and preferences compared to control Of the six included studies, none evaluated satisfaction with the SDM process. These interventions may reduce conflict in the decision made, based on two measures, Decisional Conflict Scale scores (mean difference (MD) -1.60, 95% CI -4.21 to 0.87; conflict scale from 0 to 100; 4 studies; 1714 women; very low certainty evidence) and the proportion of women with residual conflict compared to control at one to three months' follow-up (rate of women with a conflicted decision, RR 0.75, 95% CI 0.56 to 0.99; 1 study; 1001 women, very low certainty evidence). Knowledge of all options was assessed through knowledge scores and informed choice. The effect of SDM may enhance knowledge (MDs ranged from 0.47 to 1.44 higher scores on a scale from 0 to 10; 5 studies; 2114 women; low certainty evidence) and may lead to higher rates of informed choice (RR 1.24, 95% CI 0.95 to 1.63; 4 studies; 2449 women; low certainty evidence) compared to control at one to three months' follow-up. These interventions may result in little to no difference in anxiety (MD 0.54, 95% -0.96 to 2.14; scale from 20 to 80; 2 studies; 749 women; low certainty evidence) and the number of women with worries about cancer compared to control at four to six weeks' follow-up (RR 0.88, 95% CI 0.73 to 1.06; 1 study, 639 women; low certainty evidence). Other review outcomes were not measured. Enhanced communication about risks without other SDM aspects compared to control Of 11 studies, three did not report relevant outcomes for this review, and none assessed satisfaction with the SDM process. Confidence in the decision made was measured by decisional conflict and anticipated regret of participating in screening or not. These interventions, without addressing values and preferences, may result in lower confidence in the decision compared to regular communication strategies at two weeks' follow-up (MD 2.89, 95% CI -2.35 to 8.14; Decisional Conflict Scale from 0 to 100; 2 studies; 1191 women; low certainty evidence). They may result in higher anticipated regret if participating in screening (MD 0.28, 95% CI 0.15 to 0.41) and lower anticipated regret if not participating in screening (MD -0.28, 95% CI -0.42 to -0.14). These interventions increase knowledge (MD 1.14, 95% CI 0.61 to 1.62; scale from 0 to 10; 4 studies; 2510 women; high certainty evidence), while it is unclear if there is a higher rate of informed choice compared to regular communication strategies at two to four weeks' follow-up (RR 1.27, 95% CI 0.83 to 1.92; 2 studies; 1805 women; low certainty evidence). These interventions result in little to no difference in anxiety (MD 0.33, 95% CI -1.55 to 0.99; scale from 20 to 80) and depression (MD 0.02, 95% CI -0.41 to 0.45; scale from 0 to 21; 2 studies; 1193 women; high certainty evidence) and lower cancer worry compared to control (MD -0.17, 95% CI -0.26 to -0.08; scale from 1 to 4; 1 study; 838 women; high certainty evidence). Other review outcomes were not measured. AUTHORS' CONCLUSIONS: Studies using abbreviated forms of SDM and other forms of enhanced communications indicated improvements in knowledge and reduced decisional conflict. However, uncertainty remains about the effect of SDM on supporting women's decisions. Most studies did not evaluate outcomes considered important for this review topic, and those that did measured different concepts. High-quality randomised trials are needed to evaluate SDM in diverse cultural settings with a focus on outcomes such as women's satisfaction with choices aligned to their values.

RESUMEN

Background: During the first wave of the pandemic, a constant concern of healthcare workers, who are more vulnerable to contagion, is their personal safety. This is directly related to the availability of adequate PPE, which led to a perception of dissatisfaction and inequality with government responses. We aim t o determines whether perception of adequate PPE availability is associated with depressive, anxiety, and stress symptoms in different types of healthcare workers. Methods: Analytical cross-sectional study surveyed clinical and non-clinical healthcare workers in two third-level hospitals in Lima, Peru. An online self-survey assessed the perception of adequate PPE availability, using a Likert scale question, which was then dichotomized for the analysis. In addition, we assessed the depressive, anxiety, and stress symptoms using validated questionnaires. Results: 563 participants were included. In general, there is no association between perception of PPE availability and three mental health outcomes. However, in the subgroup analysis, physicians with better perception of PPE availability had less moderate-severe outcomes in mental health; in contrast, nurses had higher moderate-severe outcomes. The type of profession in healthcare workers may modify the effect of this association. Conclusion: The association between perception of PPE availability and mental health outcomes is complex in healthcare workers from two third-level hospitals. This association can vary according to the type of work.

RESUMEN

BACKGROUND: Telemedicine has become more relevant during the COVID-19 pandemic. However, medical students and professionals do not acquire competences in telemedicine during their training. Our objective was to describe the self-reported perception and baseline knowledge of telemedicine among medical students and professionals enrolled in a virtual course. METHODS: Cross-sectional study that included physicians or medical students aged 18 years or older who were interested in a free virtual telemedicine course and who completed the data collection questionnaire. We used a Likert scale to assess the self-reported perceptions of four domains related to telemedicine. The participants were grouped into three levels for each domain: low, medium and high. We also objectively assessed telemedicine knowledge by means of 10 questions, with a cut-off point of 50% of correct answers. The Fisher's exact test, the Chi-square test, and the Mann-Whitney U test were used for the comparison of categorical data. A p-value < 0.05 was considered statistically significant. RESULTS: We included 161 participants: 118 medical students and 43 physicians. We observed no significant differences between medical students and physicians in self-reported perceptions of knowledge, security, or utility of telemedicine. However, students had a high self-reported perception of the disadvantages of telemedicine especially related to patient security (p = 0.018), efficiency of care (p = 0.040), and the possibility of medical malpractice (p = 0.010) compared to physicians. Nearly half of the students (n = 53,44.9%) and physicians (n = 22,51.7%) answered 50% or more of the questions related to telemedicine knowledge correctly. CONCLUSION: Among the physicians and medical students enrolled in the course, the students perceived the disadvantages of telemedicine more frequently. Although physicians and students have limited knowledge of telemedicine, there appears to be no influence of experience and prior training in telemedicine.

RESUMEN

Background: Medical schools are increasingly including evidence-based medicine (EBM) courses in their curricula. However, little is known about the characteristics of these courses in Peru. Therefore, the present study aimed to describe the characteristics and topics addressed by undergraduate courses on EBM in Peruvian medical schools, and to compare the content of these courses with predefined EBM competencies. Methods: We conducted a cross-sectional study. We obtained the syllabi of undergraduate EBM courses from all medical schools for the latest year available. We extracted their characteristics and categorized the topics they included according to the five steps necessary to apply EBM, divided into 22 competencies. Results: In 2021, Peru had 47 universities with active undergraduate medical schools, of which 9 (19.1%) had EBM courses. These courses were not mandatory in three of the universities, and were typically offered between the 2nd and 5th year of the degree program. When analysing the topics covered in the syllabi, we found that they addressed 7 to 13 of the 22 core competencies evaluated. The least addressed topics belonged to steps 4 (apply) and 5 (evaluate) of the EBM process. Conclusion: We found that few Peruvian universities offer EBM courses, and that these courses have heterogeneous characteristics, with syllabi that do not include all essential topics for applying the five steps of EBM.

RESUMEN

Fibromyalgia is characterised by widespread musculoskeletal pain, which may present with fatigue, depression, anxiety, sleep and cognitive disturbances. It is the second most prevalent rheumatic disease. An accurate diagnosis is challenging, since its symptoms may resemble diverse conditions such as carpal tunnel syndrome, Raynaud syndrome, Sjögren syndrome, amongst others. Neuropathic pain and autonomic dysfunction in fibromyalgia suggest the involvement of the nervous system. Ion channels, neurotransmitters and neuromodulators may play a role. Small fibre neuropathy (SFN) may also cause chronic widespread pain. SFN may occur in 50% of fibromyalgia patients, but its role in the disease is unknown. Despite several efforts to synthesise the evidence on the mechanisms for pain in fibromyalgia, there are few studies applying an integrative perspective of neurochemical, immunological, and neuroanatomical characteristics, and their relevance to the disease. This protocol aims to clarify the mechanisms of the central and peripheral nervous system associated with pain in fibromyalgia. We will retrieve published studies from Web of Science, MEDLINE, Scopus, EBSCOhost, Ovid and Google Scholar. All clinical studies or experimental models of fibromyalgia reporting imaging, neurophysiological, anatomical, structural, neurochemical, or immunological characteristics of the central or peripheral nervous systems associated with pain will be included. Exclusion criteria will eliminate studies evaluating pain without a standardised measure, studies written in languages different from Spanish or English that could not be appropriately translated, and studies whose full-text files could not be retrieved after all efforts made. A narrative synthesis will be performed.

RESUMEN

PURPOSE: To assess health-related quality of life (HRQoL) and its associated factors in patients who survived COVID-19 and to assess a prospective evaluation of the prevalence and severity of their depression and anxiety symptoms. METHODS: We followed up a sample of hospitalized patients who survived COVID-19 at 3 and 12 months after discharge. We assessed HRQoL (Euroqol-5D-5L) through telephone interviews. Any problem in any dimension of Euroqol-5D-5L was considered as low HRQoL. The depression and anxiety symptoms were measured using the Patient Health Questionnaire-9 and Generalized Anxiety Disorder-7 tools, respectively. We estimated the adjusted prevalence ratios (aPR) to low HRQoL using Poisson regression and the changes on their depression and anxiety symptoms during the follow-up. RESULTS: We included 119 patients with a mean follow-up time of 363.6 days. 74% of the participants had low HRQoL at one year after hospital discharge and were associated with being ≥ 41 years old (aPR: 1.95), having a previous history of psychiatric diagnoses before COVID-19 infection (aPR: 1.47), having any COVID-19 symptom during the follow-up at one year (aPR: 1.84), and having a family member who had died from COVID-19 during the first wave (aPR: 1.24). In addition, the clinically relevant depression symptoms were frequent, and they increased from 3 (14.3%) to 12 months (18.5%). CONCLUSION: One year after COVID-19 hospitalization discharge, patients had low HRQoL, and their depression symptoms increased. These findings acknowledge the need to provide services that adequately address mental health sequels and HRQoL to reduce the burden of the COVID-19.

RESUMEN

The current coronavirus disease-2019 (COVID-19) pandemic constitutes a significant public health problem worldwide, as well as mental health problems. This study aimed to evaluate the mental health of COVID-19 survivors, considering their sociodemographic, clinical, and immune variables. A cross-sectional and correlational study was conducted on 318 COVID-19 survivors from one hospital in Peru. Through telephone interviews, evaluation of the presence of depressive symptoms using the Patient Health Questionnaire-9, anxiety symptoms through the Generalized Anxiety Disorder-7, somatic symptoms through Patient Health Questionnaire-15, and posttraumatic stress disorder (PTSD) symptoms through Impact of Event Scale-Revised was carried out. Poisson regression analyses were performed with their adjusted variances to calculate the prevalence ratio (PR) with their 95% confidence interval. All regression models were adjusted (PRa) for follow-up time. A significant proportion of patients have depressive (30.9%), anxious (31.1%), somatic (35.2%), and PTSD (29.5%) symptoms. The variables associated with a higher frequency of clinically relevant mental symptoms were female sex, self-perception of greater COVID-19 severity, presence of persistent COVID-19 symptoms, loss of a family member due to COVID-19, and prior psychiatric diagnosis or treatment. In addition, the neutrophil-to-lymphocyte ratio was significantly higher in patients with clinically relevant symptoms of depression. COVID-19 survivors showed a high prevalence of negative mental symptoms. Our findings help to identify patients who are vulnerable and require psychiatric care.

RESUMEN

Antecedentes: El Lupus Eritematoso Sistémico (LES) de inicio tardío es raro y afecta a adultos mayores. Reporte del caso: Se reporta a una mujer de 71 años con debilidad generalizada y pérdida de fuerza muscular, que aumentó súbitamente luego de un accidente cerebrovascular hemorrágico. La paciente presentó evolución tórpida por seis meses. El diagnóstico de LES de inicio tardío fue confirmado con anticuerpos antinucleares (+) y cumplimiento de criterios para LES y neurolupus, teniendo una mejoría significativa a las dos semanas de tratamiento. Luego de realizar una revisión sistemática rápida se encontraron pocos casos similares con neuropatía periférica. Conclusión: Es necesario considerar al LES de inicio tardío con neuropatía periférica en adultos mayores con debilidad muscular, como una presentación clínica atípica y la necesidad de exámenes confirmatorios.

Background: Late-onset Systemic Lupus Erythematosus (SLE) is rare and affects older adults. Case report: A 71-year-old woman is reported with generalized weakness and muscle strength loss, which increased suddenly after a hemorrhagic stroke. The patient presented a torpid evolution for six months. The diagnosis of late-onset SLE was confirmed with antinuclear antibodies (+) and compliance with criteria for SLE and neurolupus, with significant improvement after two weeks of treatment. We made a rapid systematic review and found few similar cases with peripheral neuropathy. Conclusion: It is necessary to consider late-onset SLE with peripheral neuropathy in older adults with muscle weakness, as an atypical clinical presentation and the need for confirmatory tests.

Reporte del caso: Recién nacido varón de 34 semanas de edad gestacional con ultrasonidos obstétricos que muestran higroma quístico, hidronefrosis renal bilateral, y polihidramnios. Al nacimiento, presentó edema nucal, puente nasal ancho, pabellón auricular de implantación baja, y criptorquidia derecha. Además, defecto del tabique auricular, ausencia de vena cava inferior, hipertensión pulmonar, conducto arterioso persistente y dificultad respiratoria. El resultado del análisis del panel de 14 genes mostró una mutación del gen MAP2K1 y una variante de significado incierto en el gen CBL, confirmando el diagnóstico del síndrome de Noonan negativo para PTPN11. Durante el seguimiento, también se le diagnosticó blefaroptosis izquierda y reflujo gastroesofágico. Conclusión: El presente caso destaca la amplia variedad de características fenotípicas en un paciente con síndrome de Noonan, con sospecha al nacimiento y confirmado durante el seguimiento.

Background: Noonan syndrome is a genetic disorder mostly related to PTPN11 gene mutation. Report Case: Newborn male of 34 weeks of gestational age with obstetric ultrasounds showing cystic hygroma, bilateral renal hydronephrosis, and polyhydramnios. At born, he presented nuchal edema, wide nose, low-set ears, and right cryptorchidism. Additionally, he presented atrial septum defect, absence of inferior vena cava, mild pulmonary hypertension, persistent ductus arteriosus, and respiratory distress. The result of the 14-gene panel analysis showed a MAP2K1 gene mutation and a variation of uncertain significance in the CBL gene, confirming the diagnosis of PTPN11- negative Noonan syndrome. During the follow-up, he was additionally diagnosed with blepharoptosis of left eye and gastroesophageal reflux disease. Conclusion:This report highlights the wide variety of phenotypical characteristics in a Noonan syndrome patient, which was suspected upon birth and developed during the follow-up.

RESUMEN

Resumen Objetivo: Sintetizar las características epidemiológicas y clínicas de los niños de COVID-19 con EK, KLD y MIS-C. Métodos: Se realizó una búsqueda en 4 bases de datos y preprints hasta el 31 de Mayo del 2021. Se incluyeron reportes/series de caso que evaluaron las caracte rísticas clínicas del EK, KLD o MIS-C en pacientes pediátricos con COVID-19. Resultados: Se incluyeron 16 estudios (seis informes de casos y diez series de casos, 367 pacientes en total, 58 pacientes con EK, 87 con KLD y 290 pacientes con MIS-C); con edades entre los 6 meses y los 10 años, y el 62% eran mujeres. Se observó COVID-19 positivo en 75,2%. Respecto a EK, KLD y MIS-C, las características clínicas repor tadas fueron compatibles con los cuadros diagnósticos estandarizados en el contexto de COVID-19. La duración de la hospitalización fue de 5 a 14 días para EK y de 4,3 a 13 para MIS-C. Once pacientes con MIS-C (2,8%) necesitaron ECMO. Seis pacientes con MIS-C fueron reportados muertos. Ocho estudios reportaron pacientes en la UCI. Conclusiones: EK o KLD puede asociarse a COVID-19 en niños, y pueden complicarse con MIS-C. El tiempo de hospitalización es prolongado si se presenta EK o KLD asociado a COVID-19 en niños.

Abstract Objective: To synthesize the epidemiological and clinical characteristics of COVID-19 children with MIS-C, KLD and EK. Methods: Databases and preprints were searched until May 31, 2021. Reports/case series that evaluated the clinical features of EK, KLD, or MIS-C in pediatric patients with COVID-19 were included. Results: Sixteen studies were included (six case reports and ten case series, 367 patients total, 58 patients with EK, 87 with KLD, and 290 patients with MIS-C); with ages ranging from 6 months to 10 years, and 62% were female. Positive COVID-19 was observed in 75.2%. Regarding EK, KLD and MIS-C, the reported clinical characteristics were compatible with the standardized diagnostic pictures in the context of COVID-19. The duration of hospitalization was 5 to 14 days for EK and 4.3 to 13 for MIS-C. Eleven patients with MIS-C (2.8%) needed ECMO. Eleven patients with MIS-C (2.8%) needed ECMO. Six patients with MIS-C were reported dead. Eight studies reported patients in the ICU. Conclusions: Children with COVID-19 develop EK or KLD, and can be complicated by MIS-C. Prevention, diagnosis, and treatment measures are needed.

RESUMEN

BACKGROUND: We investigated some of the factors associated with depression, perceived stress, and anxiety in clinical and nonclinical healthcare workers of two hospitals. METHODS: A mixed-methods approach was used. The sample included clinical (physicians, nurses, and others) and nonclinical (security and cleaning staff) healthcare workers of two tertiary hospitals in Peru. Participants completed an online self-survey. In the qualitative analysis, data were subjected to thematic analysis. RESULTS: We analyzed data from 613 participants, of which 8.6%, 9.0%, and 78.2% had moderate-to-severe anxiety, depression, and perceived stress, respectively. Having a previous mental health problem, being concerned about losing one's job, having at least two COVID-19 symptoms in the preceding two weeks, and being afraid of infecting family members increased the prevalence of experiencing moderate-to-severe depression and anxiety. The qualitative analysis allowed us to identify five recurring factors that caused a negative impact on workers' lives during the pandemic: emotional distress linked to hospital experiences of suffering and death, modification of routines, fear of COVID-19, exacerbation of mental disorders, and physical problems associated with emotional distress. CONCLUSIONS: Clinical and nonclinical healthcare workers in Peru have experienced depression, anxiety, and stress during the COVID-19 pandemic. Future research and interventions are necessary to improve psychological support for hospital workers.

RESUMEN

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.

RESUMEN

Introducción: Uno de los indicadores del impacto del establecimiento de prioridades en investigación en salud es la producción científica. EsSalud planteó nueve temas de investigación prioritarios (TIP) y 20 preguntas de investigación prioritarias (PIP) 2017-2019. Evaluamos el alineamiento a estas prioridades de investigación en los artículos científicos publicados con filiación de EsSalud durante 2017-2020, y caracterizamos aquellos financiados por esta institución. Material y Métodos: Análisis de los artículos científicos registrados en la base de datos de producción científica de EsSalud 2017-2020. Empleamos una metodología estandarizada y por duplicado para evaluar el alineamiento a los TIP y PIP 2017-2019 de EsSalud. La evaluación del alineamiento a las PIP sólo lo realizamos en artículos originales y resúmenes de congreso. Reportamos frecuencias de alineamiento a cada TIP y PIP, y frecuencia de alineamiento a por lo menos un TIP según características de los artículos. Además, se reportó las características de los artículos financiados por EsSalud. Resultados: Un total de 170 de 1283 artículos se alinearon a al menos un TIP. Ocho de las veinte PIP no fueron respondidas. Los artículos con autores que pertenecen o recibieron financiamiento del IETSI-EsSalud tuvieron la mayor tasa de alineación. Finalmente, los artículos financiados por EsSalud fueron principalmente estudios observacionales, guías de práctica clínica y revisiones sistemáticas. Conclusión: Los artículos científicos publicados con filiación de EsSalud durante el 2017 al 2020 tienen baja alineación con las prioridades de investigación de la institución. Por lo tanto, es necesario generar un proceso de gestión de implementación, seguimiento y evaluación de las prioridades de investigación en la institución.

Background: One of the impact indicators of priorities in health research-setting is the scientific production that refers to these priorities. EsSalud raised nine priority research topics (PRT) and 20 priority research questions (PRQ) for the 2017-2019 period. We assess the alignment to these research priorities in the scientific articles published during the 2017-2020 period by EsSalud, and we characterize those financed by this institution. Material and Methods: Analysis of the scientific articles registered in the EsSalud scientific production database for the period 2017-2020. We used a standardized methodology and in duplicate to evaluate the alignment of a scientific article to the PRTand PRQ 2017-2019 of EsSalud. The evaluation of the alignment to the PRQs is only carried out in original articles and congress summaries. We report alignment frequencies to each PRTand PRQ, and we report the frequency of alignment to at least one PRT according to the articles' characteristics. In addition, the characteristics of the articles financed by EsSalud were reported. Results: 170 out of 1283 articles were aligned to at least one PRT. Eight of the twenty PRQs went unanswered. Articles with authors who belong to or received funding from IETSI-EsSalud had the highest alignment rate. Finally, the highly cited articles financed by EsSalud were mainly observational studies, clinical practice guidelines and systematic reviews. Conclusion: The articles published by EsSalud during 2017 to 2020 have low alignment with institutional research priorities. Furthermore, it is necessary a process of implementation, monitoring, and evaluation of research priorities in the institution.

RESUMEN

BACKGROUND: The use of technologies has served to reduce gaps in access to treatment, and digital health interventions show promise in the care of mental health problems. However, to understand what and how these interventions work, it is imperative to document the aspects related to their challenging implementation. OBJECTIVE: The aim of this study was to determine what evidence is available for synchronous digital mental health implementation and to develop a framework, informed by a realist review, to explain what makes digital mental health interventions work for people with mental health problems. METHODS: The SPIDER (Sample, Phenomenon of Interest, Design, Evaluation, and Research type) framework was used to develop the following review question: What makes digital mental health interventions with a synchronous component work on people with mental health problems, including depression, anxiety, or stress, based on implementation, economic, quantitative, qualitative, and mixed methods studies? The MEDLINE, EBM Reviews, PsycINFO, EMBASE, SCOPUS, CINAHL Complete, and Web of Science databases were searched from January 1, 2015, to September 2020 with no language restriction. A Measurement Tool to Assess Systematic Reviews-2 (AMSTAR-2) was used to assess the risk of bias and Confidence in Evidence from Reviews of Qualitative Research (CERQual) was used to assess the confidence in cumulative evidence. Realist synthesis analysis allowed for developing a framework on the implementation of synchronous digital mental health using a grounded-theory approach with an emergent approach. RESULTS: A total of 21 systematic reviews were included in the study. Among these, 90% (n=19) presented a critically low confidence level as assessed with AMSTAR-2. The realist synthesis allowed for the development of three hypotheses to identify the context and mechanisms in which these interventions achieve these outcomes: (1) these interventions reach populations otherwise unable to have access because they do not require the physical presence of the therapist nor the patient, thereby tackling geographic barriers posed by in-person therapy; (2) these interventions reach populations otherwise unable to have access because they can be successfully delivered by nonspecialists, which makes them more cost-effective to implement in health services; and (3) these interventions are acceptable and show good results in satisfaction because they require less need of disclosure and provide more privacy, comfortability, and participation, enabling the establishment of rapport with the therapist. CONCLUSIONS: We developed a framework with three hypotheses that explain what makes digital mental health interventions with a synchronous component work on people with mental health problems. Each hypothesis represents essential outcomes in the implementation process.

RESUMEN

AIM AND METHOD: To determine the effect on decisional-related and clinical outcomes of decision aids for depression treatment in adults in randomised clinical trials. In January 2019, a systematic search was conducted in five databases. Study selection and data extraction were performed in duplicate. Meta-analyses were performed, and standardised and weighted mean differences were calculated, with corresponding 95% confidence intervals. The certainty of the evidence was evaluated with GRADE methodology. RESULTS: Six randomised clinical trials were included. The pooled estimates showed that decision aids for depression treatment had a beneficial effect on patients' decisional conflict, patient knowledge and information exchange between patient and health professional. However, no statistically significant effect was found for doctor facilitation, treatment adherence or depressive symptoms. The certainty of the evidence was very low for all outcomes. CLINICAL IMPLICATIONS: Using decision aids to choose treatment in patients with depression may have a a beneficial effect on decisional-related outcomes, but it may not translate into an improvement in clinical outcomes.

RESUMEN

Background: The COVID-19 pandemic significantly impacted the mental and emotional health of the elderly, especially those from low to middle-income countries. However, COVID-19 vaccination may reduce this influence. Therefore, we aimed to estimate the effect of vaccination against COVID-19 on the emotional health of older adults. Methods: We selected a national, random, and stratified sample of non-hospitalized adults aged 60 to 79 years from Peru who intended to receive or had already received the COVID-19 vaccine during recruitment. During June and July 2021, the assessed outcomes were the fear, anxiety, and worry about COVID-19, general anxiety, and depression at baseline and after a month. We estimated the adjusted odds ratios (aOR) and 95% confidence intervals (95% CI) for each altered emotional health outcomes in those who had one and two doses, compared with those who were not vaccinated using multilevel logistic regression with mixed effects. Results: We recruited 861 older adults with 20.8% of loss to follow-up. At baseline, 43.9% had received only one dose of the vaccine, and 49.1% had two doses. In the analysis during follow-up, those who had two doses had less fear (aOR: 0.19; CI 95%: 0.07 to 0.51) and anxiety to COVID-19 (aOR: 0.45; CI 95%: 0.22 to 0.89), compared to unvaccinated. We observed no effects in those with only one dose. Conclusions: Two doses of COVID-19 vaccination in older adults improves their perception of COVID-19 infection consequences. This information could be integrated into the vaccination campaign as an additional beneficial effect.

RESUMEN

Introducción: Las escuelas de medicina en Perú tienen un papel importante en la producción científica y el desarrollo en salud del país. Las Sociedades Científicas de Estudiantes de Medicina promueven la investigación entre sus miembros. Sin embargo, no se conocen la evolución y el impacto de su producción científica en sus respectivas universidades. Objetivo: Describir la producción científica de las Sociedades Científicas de Estudiantes de Medicina en Perú durante el período 2002-2018. Métodos: Estudio descriptivo, que analizó los artículos científicos publicados durante 2002-2018 por alguna de las Sociedades Científicas de Estudiantes de Medicina que estuvieron afiliadas a la Sociedad Científica Médico Estudiantil Peruana. Estos artículos se recolectaron mediante una búsqueda sistemática y por autorreporte de los miembros de las sociedades. Además, en cada caso se calculó el aporte a la producción científica en Scopus de las universidades de origen. Resultados: La Sociedad Científica Médico Estudiantil Peruana registró 39 Sociedades Científicas de Estudiantes de Medicina afiliadas, las cuales publicaron 856 artículos científicos entre 2002 y 2018. Existió una tendencia creciente del número de artículos. Del total de estos, 407 (47,6 por ciento) fueron originales, 390 (45,6 por ciento) estaban indizados a Scopus y 580 (67,8 por ciento) tenían como primer autor a un miembro de alguna sociedad. La mediana de artículos por Sociedades Científicas de Estudiantes de Medicina resultó de 11 (rango: 1 a 154). Durante el período 2015-2018, en 9/34 universidades, las Sociedades Científicas de Estudiantes de Medicina aportaron más de la cuarta parte de la producción científica de su universidad a Scopus. Conclusiones: Las Sociedades Científicas de Estudiantes de Medicina presentaron variable producción científica y en varios casos aportaron significativamente a la producción de artículos científicos de sus universidades(AU)

RESUMEN

RESUMEN Antecedentes y objetivo: La insuficiencia renal es una de las complicaciones extrapulmonares más frecuente en pacientes hospitalizados con COVID-19 condicionando peores desenlaces. Sin embargo, estudios comparan pacientes con insuficiencia renal aguda (IRA) o crónica (ERC) con pacientes sanos. Determinar características clínicas de pacientes con COVID-19 e insuficiencia renal hospitalizados y evaluar el efecto del tipo de insuficiencia renal y el recibir hemodiálisis en los desenlaces clínicos negativos. Métodos: Cohorte descriptiva que incluyó pacientes con algún tipo de insuficiencia renal y COVID-19 hospitalizados durante marzo y julio del 2020, que tuvieron una interconsulta con nefrología. La insuficiencia renal se clasificó como aguda, crónica, y crónica en estadio V con hemodiálisis crónica. Se recolectó información sobre mortalidad, uso de inotrópicos, ventilación mecánica y recibir hemodiálisis aguda. Resultados: Se analizó a 279 pacientes, 22.6 % tenían IRA, 33.3 % tenían ERC, y 44.1 % tenían ERC V. Se describe una mortalidad general de 32.9 %. Entre los pacientes con IRA y ERC el 12.9 % recibió hemodiálisis por primera vez. El desarrollo de IRA se asoció a ventilación mecánica (RPa: 6.46), uso de inotrópicos (RPa: 7.02) y fallecer (RPa: 2.41), en comparación con los que tenían sólo ERC. Entre quienes tenían IRA o ERC, aquellos que recibieron hemodiálisis por primera vez tienen mayor prevalencia de fallecer (RPa: 2.95; IC95%:2.20 a 3.94) en comparación con los que no recibieron hemodiálisis. La hemodiálisis aguda podría ser un modificador de efecto de la asociación entre tipo de insuficiencia renal (IRA o ERC) y desenlaces clínicos negativos (p<0.001). Conclusión: Es importante identificar a pacientes hospitalizados por COVID-19 que desarrollan IRA y/o necesitan hemodiálisis aguda pues se encuentran en alto riesgo de tener una mala evolución clínica.

ABSTRACT Introduction: Kidney failure is one of the most frequent extrapulmonary complications in patients hospitalized with COVID-19, leading to poorer outcomes, and this may have serious consequences for the Peruvian health system. Nonetheless, there are studies comparing patients with acute kidney failure (AKF) and chronic kidney failure (CKF) against healthy subjects. Objective: To determine the clinical characteristics of hospitalized patients with COVID-19 and kidney failure, and to assess the effect of the type of kidney failure and undergo hemodialysis with respect to negative clinical outcomes. Methods: This is a descriptive cohort study that included patients with some kind of kidney failure and COVID-19 who were hospitalized between March and June 2020, and who had a consultation with the nephrology service. Kidney failure was classified as acute, chronic, and stage V chronic undergoing chronic hemodialysis. Data with respect to mortality, inotrope use, mechanical ventilation, and acute hemodialysis was collected. Results: Two-hundred and seventy-nine patients were included, 22.6% had acute kidney failure, 33.3% had chronic kidney failure, and 44.1 had stage V chronic kidney failure. General mortality rate was 32.0%, and 27% received inotrope agents and underwent mechanical ventilation. Amongst patients with AKF and CKF, 12.9% underwent hemodialysis for the first time. Studied adult subjects with CKD and stage V CKD undergoing hemodialysis had lower frequency of diabetes mellitus (23.7% and 43.9%, respectively) and high blood pressure (31.2% and 59.4%, respectively) compared with adult subjects with AKF (81.0 and 73%, respectively) (p<0.001). The occurrence of AKF was associated with mechanical ventilation (RPa: 6.46), inotrope use (RPa: 7.02), and death (RPa: 2.41), compared with those who had CKF. Amongst those subjects who had AKF or CKF, those who underwent dialysis for the first time were more likely to die (RPa: 2.95; 95% CI: 2.20-3.94) compared with those who did not undergo hemodialysis. Acute hemodialysis may be an effect modifier for the association between the type of kidney failure (AKF or CKF) and negative clinical outcomes (p<0.001). Conclusion: It is important to identify hospitalized patients with COVID-19 that may develop AKF and/or who may need acute hemodialysis, since they are at high risk for a poor clinical outcome.

RESUMEN

BACKGROUND: Stroke represents one of the major causes of death and long-term disability worldwide and, even when new treatment strategies have been identified, there is a need of quality clinical practice guidelines (CPGs) to guide and improve acute stroke care. We aim to describe the characteristics and assess the quality of CPGs in endovascular treatment for acute ischemic stroke due to anterior-circulation large-vessel occlusion. METHODS: We conducted a scoping review of CPGs that assessed stroke management. We searched the following databases: PubMed, TripDatabase, Scopus, and Google Scholar to identify CPGs published or updated in the last 3 years and used Appraisal of Guidelines Research and Evaluation II to assess the quality of the guidelines. RESULTS: We found a total of 9 CPGs published or updated between 2018 and 2020, from which only one third had adequate methodologic rigor. Guidelines presented pitfalls related to evidence search, assessment, and methods used to reach the recommendations. All the CPGs considered a 24-hour extended window of treatment and the CPGs considered the use of similar imaging techniques to diagnose and explore the extent of the stroke. However, there were variations regarding the selection criteria for thrombectomy. CONCLUSIONS: The quality of the CPGs varied widely, which issues around the identification and assessment of the evidence used to reach recommendations. Despite this, the recommendations regarding the use of thrombectomy were similar across the CPGs. Readers need to carefully assess the methodologic rigor of CPGs before applying them to their clinical practice.

RESUMEN

Introducción: La producción científica de EsSalud ha aumentado progresivamente. Sin embargo, no se ha descrito su producción científica e identificado sus redes de colaboración en las principales bases de datos bibliográficas a nivel internacional. Objetivos: Describir la producción científica de EsSalud en revistas científicas indizadas durante el periodo 2008-2020. Material y Métodos: Estudio bibliométrico que evaluó artículos científicos y resúmenes de congresos, con al menos una filiación institucional relacionada a EsSalud entre sus autores, que se encuentren indizadas en las bases de datos bibliográficas de Scopus, Web of Science, Ovid-Medline o Scielo Citation Index durante el periodo 2008-2020. Se reporta la producción científica anual total y por separado, según base. Se identificaron las redes de colaboración intra y extrainstitucionales. Resultados: Se obtuvieron 4159 registros y, tras aplicar los criterios de selección, quedaron 2333 artículos. Se observó un incremento de publicaciones en todas las bases de datos, excepto en Scielo Citation Index. La mayoría de los artículos fueron originales, observacionales y autofinanciados. Dos hospitales nacionales de EsSalud aportaron casi dos tercios de toda la producción científica evaluada. Se identifico poca colaboración entre instituciones de EsSalud de Lima con las de otras regiones y entre regiones, pero sí con las universidades locales. El área médica que más fue abordada por las publicaciones científicas fue la relacionada con las especialidades de medicina clínica. Conclusiones: La producción científica de EsSalud ha aumentado y ha mejorado en calidad, con una importante colaboración con universidades locales. Es importante impulsar iniciativas que promuevan la investigación y colaboración dentro de EsSalud, en el marco de las prioridades de investigación y de las principales causas de mayor carga de enfermedad en la institución y el país.

Background: Scientific production of Social Security in Perú (EsSalud) has progressively increased. However, there is no description of its scientific production and collaboration networks in relevant international databases. Objectives: Describe the scientific production of EsSalud in indexed journals during the 2008-2020 period. Material and Methods: Bibliometric study that evaluated scientific articles and meeting abstracts,with at least one institutional affiliation related to EsSalud among its authors, indexed in the Scopus, Web of Science, Ovid-Medline, or Scielo Citation Index databases published during the period 2008-2020. The total annual scientific production is reported and separately according to base. Intra and extra-institutional collaboration networks were evaluated. 4159 records were Results: obtained and, after applying the selection criteria, 2333 articles remained. Scientific production from all data bases, except for the Scielo Citation Index, had a progressive increase. Most of articles were original, observational, and self-funded. Two national hospitals from EsSalud accounted for almost two-thirds of all analyzed scientific production. Institutions from Lima had little collaboration with other institutions from other regions, leading to little interregional collaboration. On the other side, there was a noticeable collaboration with local universities. The medical area that was most addressed by scientific publications was that related to clinical medicine specialties. EsSalud's Conclusions:scientific production number and quality had increased during last years in collaboration with local universities.It is important to promote initiatives thar boost the research and collaboration within EsSalud's institutions,emphasizing research priorities and the leading causes of national morbidity and mortality.
