Incidence of tuberculous infection in a TB-endemic city.

Current metrics for TB transmission include TB notifications, disease mortality, and prevalence surveys. These metrics are helpful to national TB programs to assess the burden of disease, but they do not directly measure incident infection in the community.To estimate incidence of Mycobacterium tuberculosis infection in Kampala, Uganda, we performed a prospective cohort study between 2014 and 2017 which enrolled of 1,275 adult residents without signs of tuberculous infection (tuberculin skin test [TST] <5 mm and no signs of TB disease) and followed them for conversion of TST at 1 year.During follow-up, 194 participants converted the TST and 158 converted by one year. The incidence density of TST conversion was 13.2 conversions/100 person-year (95% CI 11.6-15.1), which corresponds to an annual cumulative incidence of tuberculous infection of 12.4% (95% CI 10.7-14.3). Cumulative incidence was greater among older participants and among men. Among participants who reported prior exposure to TB cases, the cumulative risk was highest among those reporting exposure during follow-up.The high annual incidence of infection suggests that residents of Kampala have adequate contact for infection with undetected, infectious cases of TB as they go about their daily lives..

Prevalence of myocardial bridges in the Mexican population: A morphometric and histological analysis.

BACKGROUND: Myocardial bridge (MB) is described as an abnormal band of myocardium covering a variable portion of any coronary artery. METHODS: The current study explores the presence of MB throughout the coronary arterial system and provides a morphometric description through instrumented dissection of a sample of 100 human hearts. The study shows a higher prevalence of MB in the Mexican population than in previous reports. RESULTS: In the total sample (n=100), MB was identified in 96% of it. A total of 421 MBs were observed, with a mean of 4.38mm (±0.28) per dissected heart. The most frequently affected vessel is the anterior interventricular artery where a total of 52 MBs were found, of the total sample studied. DISCUSSION: The high prevalence of MB among Mexican patients could be the result of a genetic association for this population or the neoformation of MB after birth due to lifestyle-associated factors. Further studies are required to better understand the high prevalence of MB among Mexican subjects.

[Evolution of the perception of the safety culture of healthcare professionals in a pediatric emergency department]. / Evolución de la percepción de la cultura de seguridad de los profesionales sanitarios en una urgencia pediátrica.

BACKGROUND AND AIM: Safety culture (SC) is a fundamental tool for minimizing adverse events and improving safety and quality of care. Our objective, therefore was to analyze the evolution of the SC of healthcare professionals in a pediatric emergency department (PED) after the implementation of a risk management system for patient safety based on the UNE:EN:ISO 179003 Standard and the execution of new safe practices for Joint Commission International accreditation. At the same time describe the current strengths and weaknesses. METHODS: Quasi-experimental, single-center study. All PED professionals participated in the study. An initial measurement of SC was performed through the Hospital Survey on Patient Safety Culture (HSOPS) questionnaire of the Agency for Healthcare Research and Quality adapted to Spanish in 2014. Pro-patient safety strategies were implemented between 2015 and 2022. A subsequent measurement was performed in 2022. RESULTS: The response rate in 2014 was 55% and 78% in 2022. On both occasions the group with the highest participation was nurses with 35.1% and 34.8%, respectively. Five dimensions improved after the interventions: frequency of adverse events (25.2%, p<0.001), organizational learning (25%, p<0.001), feedback and communication about errors (22.3%, p<0.001), non-punitive response to errors (6.5%, p = 0.176), and management support (4%, p = 0.333). CONCLUSIONS: The actions carried out had a positive influence on organizational learning and the frequency of adverse events reported and communication within the team. In contrast, the perception of SC did not increase.

The ANTI-Vea-UGR Platform: A Free Online Resource to Measure Attentional Networks (Alertness, Orienting, and Executive Control) Functioning and Executive/Arousal Vigilance.

The Attentional Networks Test for Interactions and Vigilance-executive and arousal components (ANTI-Vea) is a computerized task of 32 min duration in the standard format. The task simultaneously assesses the main effects and interactions of the three attentional networks (i.e., phasic alertness, orienting, and executive control) and two dissociated components of vigilance with reasonable reliability (executive and arousal vigilance). We present this free and publicly accessible resource (ANTI-Vea-UGR; https://anti-vea.ugr.es/) developed to easily run, collect, and analyze data with the ANTI-Vea (or its subtasks measuring some attentional and/or vigilance components embedded in the ANTI-Vea). Available in six different languages, the platform allows for the adaptation of stimulus timing and procedure to facilitate data collection from different populations (e.g., clinical patients, children). Collected data can be freely downloaded and easily analyzed with the provided scripts and tools, including a Shiny app. We discuss previous evidence supporting that attention and vigilance components can be assessed in typical lab conditions as well as online and outside the laboratory. We hope this tutorial will help researchers interested in measuring attention and vigilance with a tool useful to collect data from large sample sizes and easy to use in applied contexts.

Characteristics of stroke units and stroke teams in Spain in 2018. Pre2Ictus project.

INTRODUCTION: The aim of this work is to describe the characteristics of stroke units and stroke teams in Spain. METHODS: We performed a cross-sectional study based on an ad-hoc questionnaire designed by 5 experts and addressed to neurologists leading stroke units/teams that had been operational for ≥ 1 year. RESULTS: The survey was completed by 43 stroke units (61% of units in Spain) and 14 stroke teams. A mean (standard deviation) of 4 (3) neurologists were assigned to each stroke unit/team; 98% of stroke units (and 38% of stroke teams) have an on-call neurologist available 24 hours a day, 98% of units (79% of stroke teams) included specialised nurses, 86% of units (71% of stroke teams) included a social worker, and 81% of units (71% of stroke teams) included a rehabilitation physician. Most stroke units (80%) had 4--6 beds with continuous non-invasive monitoring. The mean number of unmonitored beds was 14 (8) for stroke units and 12 (7) for stroke teams. The mean duration of non-invasive monitoring was 3 (1) days. All stroke units and 86% of stroke teams had intravenous thrombolysis available, and 81% of stroke units and 21% of stroke teams were able to perform mechanical thrombectomy, whereas the remaining centres had referral pathways in place. Telestroke systems were in place at 44% of stroke units, providing support to a mean of 4 (3) centres. Activity is recorded in clinical registries by 77% of stroke units and 50% of stroke teams, but less than 75% of data is completed in 25% of cases. CONCLUSIONS: Most stroke units/teams comply with the current recommendations. The systematic use of clinical registries should be improved to further improve patient care.

Chitosan Is Necessary for the Structure of the Cell Wall, and Full Virulence of Ustilago maydis.

Smut fungi comprise a large group of biotrophic phytopathogens infecting important crops, such as wheat and corn. U. maydis is a plant pathogenic fungus responsible for common smut in maize and teocintle. Through our analysis of the transcriptome of the yeast-to-mycelium dimorphic transition at acid pH, we determined the number of genes encoding chitin deacetylases of the fungus, and observed that the gene encoding one of them (UMAG_11922; CDA1) was the only one up-regulated. The mutation of this gene and the analysis of the mutants revealed that they contained reduced amounts of chitosan, were severely affected in their virulence, and showed aberrant mycelial morphology when grown at acid pH. When the CDA1 gene was reinserted into the mutants by the use of an autonomous replication plasmid, virulence and chitosan levels were recovered in the retro mutant strains, indicating that the CDA1 gene was involved in these features. These data revealed that chitosan plays a crucial role in the structure and morphogenesis of the cell wall during mycelial development of the fungus, and that in its absence, the cell wall becomes altered and is unable to support the stress imposed by the defense mechanism mounted on by the plant host during the infection process.

Gender Differences and Their Effects on Survival Outcomes in Lung Cancer Patients Treated With PD-1/PD-L1 Checkpoint Inhibitors: A Systematic Review and Meta-Analysis.

AIMS: Programmed cell death protein 1/programmed death ligand 1 (PD-1/PD-L1) immune checkpoint inhibitors have had a major impact on the approach to care of patients with lung cancer. An important issue that is not known is whether they benefit men and women the same. We conducted a meta-analysis of all randomised controlled trials evaluating PD-1/PD-L1 inhibition in patients with non-small cell lung cancer (NSCLC) to determine if clinical response and survival are influenced by gender. MATERIALS AND METHODS: A PubMed search was carried out to identify all randomised controlled trials evaluating PD-1/PD-L1 inhibitors compared with conventional chemotherapy in NSCLC. Random-effects meta-analysis and meta-regression were performed to assess overall survival and progression-free survival (PFS) and whether there were differences in these outcomes between men and women. RESULTS: In total, 12 studies with data for overall survival and 11 studies with data for PFS were included. Immunotherapy showed a statistically significant benefit over chemotherapy for overall survival (pooled hazard ratio = 0.72, 95% confidence interval = 0.65-0.81, P < 0.001) and progression-free survival (pooled hazard ratio = 0.62, 95% confidence interval = 0.54-0.72, P < 0.001). We did not find a statistically significant difference between men and women in terms of overall survival (males versus females: pooled hazard ratio = 0.74, 95% confidence interval = 0.66-0.83 versus pooled hazard ratio = 0.72, 95% confidence interval = 0.63-0.82, P = 0.709) or progression-free survival (males versus females: pooled hazard ratio = 0.63, 95% confidence interval = 0.53-0.75 versus pooled hazard ratio = 0.72, 95% confidence interval = 0.58-0.88, P = 0.372). CONCLUSION: This is the first systematic review and meta-analysis investigating the effect of gender and response to PD-1/PD-L1 checkpoint inhibitors in patients solely with NSCLC. We examined 9270 and 6193 patients in terms of overall survival and PFS, respectively. Although there are significant biological differences between men's and women's immune responses, we have shown that these drugs offer the same survival benefit in patients with NSCLC regardless of gender.

[Statement of the Spanish Interdisciplinary Vascular Prevention Committee on the updated European Guidelines on Cardiovascular Disease Prevention]. / Comentario del CEIPV a las nuevas Guías Europeas de Prevención Cardiovascular 2021.

Statement of the Spanish Interdisciplinary Vascular Prevention Committee on the updated European Guidelines on Cardiovascular Disease Prevention. We present the Spanish adaptation of the 2021 European Guidelines on Cardiovascular Disease (CVD) prevention in clinical practice. The current guidelines besides the individual approach greatly emphasize on the importance of population level approaches to the prevention of cardiovascular diseases. Systematic global CVD risk assessment is recommended in individuals with any major vascular risk factor. Regarding LDL-Cholesterol, blood pressure, and glycemic control in patients with diabetes mellitus, goals and targets remain as recommended in previous guidelines. However, it is proposed a new, stepwise approach (Step 1 and 2) to treatment intensification as a tool to help physicians and patients pursue these targets in a way that fits patient profile. After Step 1, considering proceeding to the intensified goals of Step 2 is mandatory, and this intensification will be based on 10-year CVD risk, lifetime CVD risk and treatment benefit, comorbidities and patient preferences. The updated SCORE algorithm-SCORE2, SCORE-OP- is recommended in these guidelines, which estimates an individual's 10-year risk of fatal and non-fatal CVD events (myocardial infarction, stroke) in healthy men and women aged 40-89 years. Another new and important recommendation is the use of different categories of risk according different age groups (< 50, 50-69 ≥ 70 years). Different flow charts of CVD risk and risk factor treatment in apparently healthy persons, in patients with established atherosclerotic CVD, and in diabetic patients are recommended. Patients with chronic kidney disease are considered high risk or very high-risk patients according to the levels of glomerular filtration rate and albumin-to-creatinine ratio. New lifestyle recommendations adapted to the ones published by the Spanish Ministry of Health as well as recommendations focused on the management of lipids, blood pressure, diabetes and chronic renal failure are included.

Dyslipidemias and stroke prevention: Recommendations of the Study Group of Cerebrovascular Diseases of the Spanish Society of Neurology.

OBJECTIVE: We present an update of the Spanish Society of Neurology's recommendations for prevention of both primary and secondary stroke in patients with dyslipidaemia. DEVELOPMENT: We performed a systematic review to evaluate the main aspects of the management of dyslipidaemias in primary and secondary stroke prevention and establish a series of recommendations. CONCLUSIONS: In primary prevention, the patient's vascular risk should be determined in order to define target values for low-density lipoprotein cholesterol. In secondary prevention after an atherothrombotic stroke, a target value <55 mg/dL is recommended; in non-atherothombotic ischaemic strokes, given the unclear relationship with dyslipidaemia, target value should be established according to the vascular risk group of each patient. In both primary and secondary prevention, statins are the drugs of first choice, and ezetimibe and/or PCSK9 inhibitors may be added in patients not achieving the target value.

Association between neuroimaging findings and neurological sequelae in patients with congenital cytomegalovirus infection.

BACKGROUND: Congenital cytomegalovirus (CMV) infection is an important cause of disability. There is little evidence on the prognostic value of lesions identified in neuroimaging studies. AIM: The study aimed to assess the severity of lesions detected with brain MRI and transfontanellar ultrasound and their relationship with long-term neurological deficits. PATIENTS AND METHODS: We performed a retrospective, analytical, observational study of 36 patients with congenital CMV infection. Neuroimaging studies were reviewed and classified according to the modified Noyola' scale. Imaging findings were compared with neurological alterations in the patients' most recent follow-up evaluation at the paediatric neurology department. RESULTS: Thirty-six patients were studied (transfontanellar ultrasound: 30; brain MRI: 29). Twenty of 30 patients showed ultrasound abnormalities; of these, 11 showed alterations on brain MR images (P = .04) and 10 had neurological impairment (P = .008). Transfontanellar ultrasound had a sensitivity of 83.3%, 90% CI: 58-100 and a specificity of 44.4%, 90% CI: 18.7-70.2 for predicting neurological sequelae. Brain MRI displayed abnormalities in 20 of 29 patients, of whom 16 had neurological impairment (P < .001). MRI had a sensitivity of 94%, 95% CI: 80-100 and a specificity of 66.6%, 95% CI: 36-97.5 for predicting neurological sequelae. Modified Noyola' scale values > 2 were correlated with psychomotor retardation (P < .001). CONCLUSIONS: Our findings validate previous studies reporting a statistical significant correlation between the extension of neuroimaging lesions and severity of neurological deficits.

Tec1, a member of the TEA transcription factors family, is involved in virulence and basidiocarp development in Ustilago maydis.

The life cycle of Ustilago maydis involves alternation of a haploid saprophytic yeast-like stage and a dikaryotic hyphal virulent form. Under in vitro conditions, basidiocarps are formed. Analysis of the transcriptional network of basidiocarp formation revealed the possible involvement of a Tec transcription factor (Tec1, UMAG_02835) in the process. In some Ascomycota, Tec factors are involved in mycelial formation, pathogenesis, and interaction with other regulatory elements, but their role in Basidiomycota species is almost unknown. Accordingly, we proceeded to determine the role of this gene in U. maydis by its mutation. Tec1 was found to be a crucial factor for normal mating, basidiocarp development, and virulence, all of the functions related to the dikaryotic stage dependent of the b genes, whereas dimorphism and resistance to different stress conditions occurring in the haploid stage were not affected in tec1 mutants. The observation that mutants showed a low residual wild-type phenotype suggests the presence of a secondary mechanism that partially compensates the loss of Tec1.

Proprotein convertase subtilisin/kexin type 9 inhibitors in secondary prevention of vascular events in patients with stroke: Consensus document and practice guidance.

INTRODUCTION: Patients with history of stroke or transient ischaemic attack present considerable risk of future vascular events. Reducing levels of low-density lipoprotein (LDL) cholesterol decreases the incidence of new vascular events, although in a substantial number of patients, the currently available lipid-lowering therapies fail to achieve the therapeutic goals recommended in clinical guidelines. The aim of this consensus statement is to provide updated information on the role of the proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors alirocumab and evolocumab in the secondary prevention of vascular events in patients with history of ischaemic stroke. METHODS: A literature review was performed to identify the main evidence on the use of PCSK9 inhibitors in these patients and the recommended therapeutic targets of LDL cholesterol. The results were discussed in 2 consensus meetings that constituted the basis for the drafting of the document. CONCLUSIONS: PCSK9 inhibitors are effective in reducing vascular risk in secondary prevention; evolocumab specifically has achieved this reduction in patients with history of ischaemic stroke. Moreover, both alirocumab and evolocumab present good safety profiles, even in patients achieving LDL cholesterol levels < 20 mg/dL, and no signs of cognitive impairment have been observed in patients treated with evolocumab who achieved very low levels of LDL cholesterol. In the light of this evidence, we provide practical recommendations about the use of PCSK9 inhibitors in secondary prevention of vascular events in patients with history of ischaemic stroke and follow-up of these patients.

Recommendations of the Spanish Society of Neurology for the prevention of stroke. Interventions on lifestyle and air pollution.

OBJECTIVE: To update the recommendations of the Spanish Society of Neurology regarding lifestyle interventions for stroke prevention. DEVELOPMENT: We reviewed the most recent studies related to lifestyle and stroke risk, including randomised clinical trials, population studies, and meta-analyses. The risk of stroke associated with such lifestyle habits as smoking, alcohol consumption, stress, diet, obesity, and sedentary lifestyles was analysed, and the potential benefits for stroke prevention of modifying these habits were reviewed. We also reviewed stroke risk associated with exposure to air pollution. Based on the results obtained, we drafted recommendations addressing each of the lifestyle habits analysed. CONCLUSIONS: Lifestyle modification constitutes a cornerstone in the primary and secondary prevention of stroke. Abstinence or cessation of smoking, cessation of excessive alcohol consumption, avoidance of exposure to chronic stress, avoidance of overweight or obesity, a Mediterranean diet supplemented with olive oil and nuts, and regular exercise are essential measures in reducing the risk of stroke. We also recommend implementing policies to reduce air pollution.

Stroke prevention in patients with arterial hypertension: Recommendations of the Spanish Society of Neurology's Stroke Study Group.

OBJECTIVE: To update the recommendations of the Spanish Society of Neurology on primary and secondary stroke prevention in patients with arterial hypertension. DEVELOPMENT: We proposed several questions to identify practical issues for the management of blood pressure (BP) in stroke prevention, analysing the objectives of blood pressure control, which drugs are most appropriate in primary prevention, when antihypertensive treatment should be started after a stroke, what levels we should aim to achieve, and which drugs are most appropriate in secondary stroke prevention. We conducted a systematic review of the PubMed database and analysed the main clinical trials to address these questions and establish a series of recommendations. CONCLUSIONS: In primary stroke prevention, antihypertensive treatment should be started in patients with BP levels >  140/90 mmHg, with a target BP of < 130/80 mmHg. In secondary stroke prevention, we recommend starting antihypertensive treatment after the acute phase (first 24 hours), with a target BP of < 130/80 mmHg. The use of angiotensin-II receptor antagonists or diuretics alone or in combination with angiotensin-converting enzyme inhibitors is preferable.

[Evaluation of the effectiveness of a procedure for identifying patients with allergy in paediatric emergency rooms]. / Evaluación de la efectividad de un procedimiento de identificación de pacientes con alergia en urgencias pediátricas.

INTRODUCTION: Correct identification of the patient with an allergy is critical for patient safety, since it involves a potential risk of a serious adverse event (AE). Our Emergency Pediatric department has an integrated quality management and risk management system focused on the continuous improvement of patient care quality and safety, which incident reporting system could identified a potential risk arising from the registration of allergies in new computer softwares. As a safety barrier, an allergy identification procedure was implemented, using a sticker placed on the identification bracelet (RED: allergy; WHITE: non-allergies). MATERIALS AND METHODS: A descriptive study was conducted to evaluate, by direct observation, the correct identification of patients with allergy using this new protocol. The reports of incidents related to this procedure were analyzed. RESULTS: Of the 342 patients included, 327 (95.6% (95%:93.4-97.8%)) were correctly identified. Identification errors were most common in the group of patients with allergies [10 of 45; 22.2% (95%:10.1-34.4%) than in the non-allergic group: 5 of 297; 1.7% (95%:0.2-3.2); p<0.001)]. No AEs were reported. 2 quasi-incidents detected before reaching the patient were reported thanks of the protocol application. CONCLUSIONS: This procedure is a useful safety barrier and can be easily exported to other units. Further work is needed to promote the professional's adherence to the protocol and improve the correct identification of the patient with allergy.

Mental health consequences of the Covid-19 outbreak in Spain. A longitudinal study of the alarm situation and return to the new normality.

AIMS: The objective is to conduct a longitudinal analysis of the effects of the pandemic and alarm situation on the mental health of the general population at three points in time: two weeks after beginning the confinement, after a month, and after two months, when the lockdown was lifted and the country returned to the new normality. METHODS: The evaluations were carried out by means of an online survey, with a sample of 3480 persons in the first data collection and 1041 and 569 persons in the successive evaluation periods. The presence of depressive symptoms, anxiety and posttraumatic stress disorder (PTSD) was evaluated by means of screening tests. Sociodemographic data, Covid-19 variables, loneliness, psychological well-being, social support, discrimination and a sense of belonging, were collected. RESULTS: Depressive symptoms increased significantly throughout the confinement, decreasing at the last assessment but not dropping to previous levels. In anxiety, there are no significant changes between the three evaluations, but a downward trend can be seen over time. Regarding the symptomatology of PTSD, a downward trend is observed throughout the three evaluations, with significantly lower scores between the first and third assessments. The different regression models developed reveal the importance of perceived loneliness and spiritual well-being as the main predictors of mental health, as well as the importance of the lower age for depression and the female gender for anxiety and PSTD. CONCLUSIONS: This research shows that the pandemic has had a negative impact on our mental health, which still does not seem to be at pre-crisis levels, although it has improved as the emergency situation subsides. These results underline the importance of paying greater attention to mental health, and reveal key variables such as spiritual well-being and perceived loneliness in which to intervene from different care services, as well as younger people and women as vulnerable groups on which to focus more attention.

Use of cardiovascular polypills for the secondary prevention of cerebrovascular disease. / Uso de la polipíldora cardiovascular en la prevención secundaria de la enfermedad cerebrovascular.

INTRODUCTION: There is little control of cardiovascular (CV) risk factors in secondary prevention after an ischaemic stroke, in part due to a lack of adherence to treatment. The CV polypill may contribute to proper treatment adherence, which is necessary for CV disease prevention. This study aimed to establish how and in what cases the CV polypill should be administered. METHODS: A group of 8 neurologists drafted consensus recommendations using structured brainstorming and based on their experience and a literature review. RESULTS: These recommendations are based on the opinion of the participating experts. The use of the CV polypill is beneficial for patients, healthcare professionals, and the health system. Its use is most appropriate for atherothrombotic stroke, lacunar stroke, stroke associated with cognitive impairment, cryptogenic stroke with CV risk factors, and silent cerebrovascular disease. It is the preferred treatment in cases of suspected poor adherence, polymedicated patients, elderly people, patients with polyvascular disease or severe atherothrombosis, young patients in active work, and patients who express a preference for the CV polypill. Administration options include switching from individual drugs to the CV polypill, starting treatment with the CV polypill in the acute phase in particular cases, use in patients receiving another statin or an angiotensin ii receptor antagonist, or de novo use if there is suspicion of poor adherence. Nevertheless, use of the CV polypill requires follow-up on the achievement of the therapeutic objectives to make dose adjustments. CONCLUSIONS: This document is the first to establish recommendations for the use of the CV polypill in cerebrovascular disease, beyond its advantages in terms of treatment adherence.

Stroke prevention in patients with type 2 diabetes or prediabetes. Recommendations from the Cerebrovascular Diseases Study Group, Spanish Society of Neurology. / Prevención de ictus en pacientes con diabetes mellitus tipo 2 o prediabetes. Recomendaciones del Grupo de Estudio de Enfermedades Cerebrovasculares de la Sociedad Española de Neurología.

OBJECTIVE: To update the Spanish Society of Neurology's guidelines for stroke prevention in patients with type 2 diabetes or prediabetes, analysing the available evidence on the effect of metabolic control and the potential benefit of antidiabetic drugs with known vascular benefits in addition to conventional antidiabetic treatments in stroke prevention. DEVELOPMENT: PICO-type questions (Patient, Intervention, Comparison, Outcome) were developed to identify practical issues in the management of stroke patients and to establish specific recommendations for each of them. Subsequently, we conducted systematic reviews of the PubMed database and selected those randomised clinical trials evaluating stroke as an independent variable (primary or secondary). Finally, for each of the PICO questions we developed a meta-analysis to support the final recommendations. CONCLUSIONS: While there is no evidence that metabolic control reduces the risk of stroke, some families of antidiabetic drugs with vascular benefits have been shown to reduce these effects when added to conventional treatments, both in the field of primary prevention in patients presenting type 2 diabetes and high vascular risk or established atherosclerosis (GLP-1 agonists) and in secondary stroke prevention in patients with type 2 diabetes or prediabetes (pioglitazone).

Video discharge instructions for pediatric gastroenteritis in an emergency department: a randomized, controlled trial.

The aim was to evaluate if the addition of video discharge instructions (VDIs) to usual verbal information improved the comprehension of information provided to caregivers of patients who consult for acute gastroenteritis (AGE). We conducted an open-label, parallel, randomized trial, enrolling patients who consulted for AGE at a tertiary hospital. First, caregivers answered a written test concerning AGE characteristics and management. They were randomly allocated to a control group, which received the usual verbal instructions, or to an intervention group, which additionally received VDI. After discharge, caregivers were contacted by telephone and answered the same test, satisfaction questions, and follow-up information. From September 2019 to March 2020, 139 patients were randomized, 118 completed follow-up. The mean score was 3.13 (SD 1.07) over 5 points in the initial test and 3.96 (SD 0.96) in the follow-up test. Patients in the intervention group had a greater improvement (1.17 points, SD 1.11) than those in the control group (0.47 points, SD 0.94, p < 0.001). In the follow-up test, 49.1% in the intervention group and 18.6% in the control group answered all questions correctly (p < 0.001). There were no significant differences in return visits. Caregivers gave high satisfaction scores regardless of the allocation group.Conclusion: Video instructions improve caregivers' understanding of discharge information.Trial registration: [NCT04463355, retrospectively registered July 9, 2020]. What is Known: • Poor comprehension of discharge instructions leads to incorrect treatment after discharge, increased readmissions and a reduction of caregivers' satisfaction. • Video discharge instructions are useful providing concise information independently of the patients' health literacy level or communication skills of the health care provider What is New: • The addition of video discharge instructions to verbal instructions improves caregivers' knowledge about AGE improved with respect to those who only receive verbal instructions • Video instructions do not add extra time to the emergency department visits.

Proprotein convertase subtilisin/kexin type 9 inhibitors in secondary prevention of vascular events in patients with stroke: Consensus document and practice guidance. / Inhibidores de la proproteína convertasa subtilisina/kexina tipo 9 (iPCSK9) en la prevención secundaria de episodios vasculares en pacientes con ictus isquémico: Documento de consenso y aplicaciones prácticas.
