[Online Cognitive Stimulation Program for Older Adults with Mild Cognitive Impairment (MCI): Feasibility Study]. / Programa de estimulación cognitiva en línea para pacientes adultos mayores con deterioro cognitivo leve: estudio de factibilidad.

BACKGROUND: Mild Cognitive Impairment (MCI) is considered a decline in cognitive functions, which becomes more pronounced with age. These patients may benefit from cognitive treatments that help attenuate or slow down a potential progression towards dementia. OBJECTIVE: To assess the feasibility, fidelity, satisfaction, and effectiveness of the Memory Training and Cognitive Stimulation Program (PEMEC, by its Spanish acronym) in individuals with MCI in an online setting. METHOD: A non-probabilistic convenience sample of 14 patients with MCI received the PEMEC (PEMEC online) through an electronic device, were assessed with MoCA, NEUROPSI Brief, Yesavage Geriatric Depression Scale before and after treatment, comparing these measurements with those of a waiting list control group. RESULTS: 92,85% completed the treatment; with an average of 92% fidelity to the original intervention, an average of 91,61% for satisfaction with the activities of each session and the perceived usefulness was 97,98%. Statistically significant differences were found in the NEUROPSI Brief and the MoCA, before and after treatment in the intervention group and, when comparing the scores with the waiting list control group, a statistically significant difference was found in the MoCA scores. CONCLUSION: Following the cultural adaptation of the program (from a Spanish to a Mexican treatment group), these results establish a precedent that systematic group cognitive interventions are feasible and effective in virtual tele-neuropsychology contexts for older adults.

Prevalence and prognostic implications of the no-reflux phenomenon in patients undergoing primary percutaneous coronary intervention at a university center in a middle-income country.

OBJECTIVE: To analyze the prevalence of no-reflow and the 30-day mortality in a university center in a middle-income country. METHOD: We analyzed 2463 patients who underwent primary PCI from January 2006 to December 2021. The outcome measure was 30-day mortality. RESULTS: Of a total of 2463 patients, no-reflow phenomenon was found in 413 (16.8%) patients, 30-day mortality was 16.7 vs. 4.29% (p < 0.001). Patients with no-reflow were older 60 (53-69.5) vs. 59 (51-66) (p = 0.001), with a higher delay in onset of symptom to emergency department arrival 270 vs. 247 min (p = 0.001). No-reflow patients also had had fewer previous myocardial infarction, 11.6 vs. 18.4 (p = 0.001) and a Killip class > 1, 37 vs. 26% (p < 0.001). No-reflow patients were more likely to have an anterior myocardial infarction (55.4 vs. 47.8%; p = 0.005) and initial TIMI flow 0 (76 vs. 68%; p < 0.001). CONCLUSION: No-reflow occurred in 16.8% of STEMI patients undergoing primary PCI and was more likely with older age, delayed presentation, anterior myocardial infarction and Killip class > 1. No-reflow was associated with a higher mortality at 30-day follow-up.

OBJETIVOS: Analizar la prevalencia de no reflujo y la mortalidad a 30 días en un centro universitario de un país de ingresos medios. MÉTODO: Analizamos 2,463 pacientes que se sometieron a ICP primaria desde enero de 2006 hasta diciembre de 2021. La medida de resultado fue la mortalidad a los 30 días. RESULTADOS: Del total de 2,463 pacientes, se encontró fenómeno de no reflujo en 413 (16.8%), la mortalidad a los 30 días fue del 16.7 vs. 4.29% (p < 0.001). Los pacientes sin reflujo tenían mayor edad 60 (53-69.5) vs. 59 (51-66) (p = 0.001), con mayor retraso del inicio de los síntomas a la llegada a urgencias, 270 vs. 247 min (p = 0.001). Los pacientes sin reflujo también tenían menos infarto de miocardio previo, 11.6 vs. 18.4 (p = 0.001), y una clase Killip > 1, 37 vs. 26% (p < 0.001). Los pacientes sin reflujo tenían más probabilidades de tener un infarto de miocardio anterior (55.4 vs. 47.8%; p = 0.005) y flujo TIMI inicial 0 (76 vs. 68%; p < 0.001). CONCLUSIÓN: Ocurrió ausencia de reflujo en el 16.8% de los pacientes con IAMCEST sometidos a ICP primaria y fue más probable con la edad avanzada, presentación tardía, infarto de miocardio anterior y clase Killip > 1. El no reflujo se asoció con una mayor mortalidad a los 30 días de seguimiento.

Feasibility of a trauma-focused internet- and mobile-based intervention for youth with posttraumatic stress symptoms.

Background: Many youth with posttraumatic stress symptoms (PTSS) do not receive evidence-based care. Internet- and Mobile-Based Interventions (IMIs) comprising evidence-based trauma-focused components can address this gap, but research is scarce. Thus, we investigated the feasibility of a trauma-focused IMI for youth with PTSS.Methods: In a one-arm non-randomized prospective proof-of-concept study, 32 youths aged 15-21 years with clinically relevant PTSS (CATS ≥ 21) received access to a trauma-focused IMI with therapist guidance, comprising nine sessions on an eHealth platform accessible via web-browser. We used a feasibility framework assessing recruitment capability, sample characteristics, data collection, satisfaction, acceptability, study management abilities, safety aspects, and efficacy of the IMI in PTSS severity and related outcomes. Self-rated assessments took place pre-, mid-, post-intervention and at 3-month follow-up and clinician-rated assessments at baseline and post-intervention.Results: The sample mainly consisted of young adult females with interpersonal trauma and high PTSS levels (CATS, M = 31.63, SD = 7.64). The IMI sessions were found useful and comprehensible, whereas feasibility of trauma processing was perceived as difficult. Around one-third of participants (31%) completed the IMI's eight core sessions. The study completer analysis showed a significant reduction with large effects in self-rated PTSS at post-treatment [t(21) = 4.27; p < .001; d = 0.88] and follow-up [t(18) = 3.83; p = .001; d = 0.84], and clinician-rated PTSD severity at post-treatment [t(21) = 4.52; p < .001; d = 0.93]. The intention-to-treat analysis indicated significant reductions for PTSS at post-treatment and follow-up with large effect sizes (d = -0.97- -1.02). All participants experienced at least one negative effect, with the most common being the resurfacing of unpleasant memories (n = 17/22, 77%).Conclusion: The study reached highly burdened young adults. The IMI was accepted in terms of usefulness and comprehensibility but many youths did not complete all sessions. Exploration of strategies to improve adherence in trauma-focused IMIs for youth is warranted, alongside the evaluation of the IMI's efficacy in a subsequent randomized controlled trial.

Youth often lack access to evidence-based care after trauma. This study assessed the feasibility of a trauma-focused internet- and mobile-based intervention with therapist guidance.The intervention was accepted by youths, and the preliminary evaluation of participant responses suggests its efficacy.Future studies should examine strategies to improve adherence and the IMI's efficacy in a RCT.

Predictors of response to a dietary intervention in patients with irritable bowel syndrome.

BACKGROUND: Different diets have emerged as potential therapeutic options for patients with irritable bowel syndrome (IBS). OBJECTIVE: To identify predictors of improvement after a low-FODMAP, low-starch and low-sucrose diet among patients with IBS. METHODS: We performed a descriptive cross-sectional study including patients with IBS according to Rome IV criteria undertaking a social-media based program with a two-week dietary intervention. Patients completed an online survey before and after the intervention including the presence of intestinal and extra-intestinal symptoms, the IBS-SSS (irritable bowel syndrome symptoms severity scale) and the PHQ-9 (patient health questionnaire-9). Clinical improvement was defined as a decrease of at least 50% in IBS-SSS post dietary intervention. Variables associated with symptomatic response were identified with logistic regression analysis. A clinical score to predict response was created and tested with a with a receiver operating characteristic (ROC) curve analysis. RESULTS: A total of 3583 patients with IBS were included. Mean IBS-SSS before and after dietary intervention was 295.5±52.32 and 240±48.66, respectively (p=0.01); 1178 (32.8%) patients showed clinical improvement. A mean basal IBS-SSS >400 (OR 3.04), chronic headache (OR 1.96), and chronic fatigue (OR 1.81) were significantly associated with symptomatic response. Patients with arthralgia (OR 0.41) and/or fibromyalgia (OR 0.33) were less likely to improve. Each variable received the following individuals scores: IBS-SSS >400: +2, chronic headache: +1.5, chronic fatigue: +1, arthralgia: -1, and fibromyalgia: -1. The ROC curve analysis of the proposed score showed an area under the curve of 0.72 (95% CI 0.69-0.76). A score ≥3 had a sensitivity of 72.64% and specificity of 60.56% for predicting symptomatic improvement. CONCLUSIONS: There are clinical variables that could serve as reliable predictors of response to a low-FODMAP, low-sucrose, low-starch diet among patients with IBS. Further research is needed to understand the link between the presence of extra-intestinal symptoms and clinical improvement after dietary interventions for IBS.

Position paper on perioperative management and surgical risk in the patient with cirrhosis.

INTRODUCTION: Management of the patient with cirrhosis of the liver that requires surgical treatment has been relatively unexplored. In Mexico, there is currently no formal stance or expert recommendations to guide clinical decision-making in this context. AIMS: The present position paper reviews the existing evidence on risks, prognoses, precautions, special care, and specific management or procedures for patients with cirrhosis that require surgical interventions or invasive procedures. Our aim is to provide recommendations by an expert panel, based on the best published evidence, and consequently ensure timely, quality, efficient, and low-risk care for this specific group of patients. RESULTS: Twenty-seven recommendations were developed that address preoperative considerations, intraoperative settings, and postoperative follow-up and care. CONCLUSIONS: The assessment and care of patients with cirrhosis that require major surgical or invasive procedures should be overseen by a multidisciplinary team that includes the anesthesiologist, hepatologist, gastroenterologist, and clinical nutritionist. With respect to decompensated patients, a nephrology specialist may be required, given that kidney function is also a parameter involved in the prognosis of these patients.

National record and analysis of pharmaceutical interventions in critical care units: PHARMACRITIC study. / Registro nacional y análisis de intervenciones farmacéuticas en unidades de cuidados críticos: estudio FARMACRITIC.

OBJECTIVE: To design a homogeneous methodology for the registration and analysis of pharmaceutical interventions performed in Spanish critical adults' care units. METHOD: Observational, prospective and multicenter study. In the first stage, a national registry of pharmaceutical interventions will be agreed upon and subsequently all the pharmaceutical interventions performed on adult patients admitted to Spanish CCUs during eight weeks will be recorded. Variables related to the type of CCU, the drug involved in the intervention, type of intervention (indication, effectiveness, safety), recommendation made by the pharmacist and the degree of acceptance will be evaluated. Risk and incidence will be calculated for each of the medication errors detected. The χ2-squared test or Fisher exact test will be used for categorical variables and Mann-Whitney U or Kruskal-Wallis test for continuous variables. All tests will be performed with a significance level α = 0.05 and confidence intervals with confidence 1- α. DISCUSSION: The results obtained from this project will make it possible to obtain a homogeneous classification of the pharmaceutical interventions performed in CCU, a national record and an evaluation of the weak points with the aim of developing strategies for improvement in the pharmaceutical care of the critically ill patient.

Effect of trauma on asylum seekers and refugees receiving a WHO psychological intervention: a mediation model.

Background: Scalable psychological interventions such as the WHO's Self-Help Plus (SH+) have been developed for clinical and non-clinical populations in need of psychological support. SH+ has been successfully implemented to prevent common mental disorders among asylum seekers and refugees who are growing in number due to increasing levels of forced migration. These populations are often exposed to multiple, severe sources of traumatisation, and evidence of the effect of such events on treatment is insufficient, especially for non-clinical populations.Objective: We aim to study the effect of potentially traumatic experiences (PTEs) and the mediating role of symptoms of posttraumatic stress disorder (PTSD) on the improvement following SH+.Method: Participants allocated to SH+ who received at least three sessions (N = 345) were extracted from two large, randomised, European prevention trials involving asylum seekers and refugees. Measures of distress, depression, functional impairment, and post-traumatic stress symptoms were administered at baseline and 6 months post-intervention, together with measures of well-being and quality of life. Adjusted models were constructed to examine the effect of PTEs on post-intervention improvement. The possible mediating role of PTSD symptoms in this relationship was then tested.Results: Increasing numbers of PTEs decreased the beneficial effect of SH+ for all measures. This relationship was mediated by symptoms of PTSD when analysing measures of well-being and quality of life. However, this did not apply for measures of mental health problems.Conclusions: Exposure to PTEs may largely reduce benefits from SH+. PTSD symptomatology plays a specific, mediating role on psychological well-being and quality of life of participants who experienced PTE. Healthcare professionals and researchers should consider the role of PTEs and PTSD symptoms in the treatment of migrants and refugees and explore possible feasible add-on solutions for cases exposed to multiple PTEs.

Increasing numbers of potentially traumatic experiences can decrease the beneficial effect of a manualized group psychotherapeutic intervention in migrants and refugees across multiple countries.In absence of a full threshold diagnosis of post-traumatic stress disorder, post-traumatic stress symptoms still mediate the relation between potentially traumatic experiences and some outcome improvements at follow-up.While the moderating role of number of potentially traumatic experiences applies to all outcomes (depression symptoms, psychological distress, functional impairment, well-being, and quality of life), the mediating role of post-traumatic stress symptoms in this relation only applies to well-being and quality of life.

Development of a stepped care intervention model of evidence-based interventions for the management of posttraumatic stress in the Belgian Police.

Background: Police officers are frequently exposed to a wide variety of potentially traumatic events (PTE) and are therefore at a considerable risk of developing posttraumatic stress disorder (PTSD). Previous research estimated the point prevalence of PTSD in Belgian police officers at 7.4%, significantly higher than in the general population. An effective organisational strategy to manage posttraumatic stress is essential.Objective: We aimed to develop a novel organisational approach regarding traumatic stress for Belgian police, combining evidence-based strategies for the prevention and treatment of posttraumatic stress in a stepped care intervention model.Method: In a broad development process, we combined scientific literature, case studies of best practices from other police organisations with insights gathered from a number of expert panels, thematic working groups and feedback groups.Results: A comprehensive stepped care intervention model was developed, consisting of evidence-based interventions for the prevention and treatment of posttraumatic stress.Conclusions: The intervention model is a promising organisational strategy for the management of posttraumatic stress in police organisations based on evidence-based interventions. Its effectiveness will be studied in the coming years.

Police officers are at considerable risk of developing PTSD as they are consistently exposed to a wide array of PTE.An adequate organisational response to manage the consequences of this exposure as much as possible is essential.We developed a comprehensive stepped care intervention model consisting of evidence-based interventions, based on scientific literature, best practices in other police organisations, and thorough expert review.

Two people making sense of a story: narrative exposure therapy as a trauma intervention in early intervention in psychosis.

Background: Narrative exposure therapy (NET) is a recommended intervention for people with multiple trauma histories; however, research is lacking into its use with people experiencing psychosis, many of whom report multiple trauma histories.Objective: This study aimed to explore experiences of NET in early intervention in psychosis (EIP) services.Method: Eight clinicians and four experts with lived experience (experts by experience) of psychosis and multiple trauma were interviewed on a single occasion using two versions (clinician and expert by experience) of a semi-structured interview schedule. Data was analysed using thematic analysis.Results: Five overarching themes were generated, relating to fear and avoidance of memories, importance of trust, organizing memories and making new meaning, reconnecting with emotions, and considerations when delivering NET in EIP.Conclusions: Directly addressing the impact of multiple trauma in people experiencing first episode psychosis is frightening and emotive, but helps to address painful memories and organize them into a personal narrative. Increases in distress and anomalous experiences were carefully considered by clinicians, but typically outweighed by the benefits of NET. Challenges were comparable to those described in non-psychosis research. Implications for clinical practice and future research are outlined.

Many people experiencing psychosis report multiple trauma histories. Narrative exposure therapy (NET) is a recommended intervention for people with multiple trauma histories, but research into its use with people experiencing psychosis is limited.This qualitative study found that clinicians and experts by experience in early intervention in psychosis services valued NET for its effect on organizing memories, reducing their emotional impact, and making new meaning around experiences, and that challenges of NET were similar to those described in non-psychosis research.Some participants described experiencing distress and dysregulation during NET, including an increase in anomalous experiences. Although this was typically temporary and outweighed by NET's benefits, careful assessment before and flexibility during the intervention are considered important for building engagement and trust.

Timing of multivessel revascularization in stable patients with STEMI: a systematic review and network meta-analysis.

INTRODUCTION AND OBJECTIVES: Multivessel percutaneous coronary intervention (MV-PCI) is recommended in patients with ST-segment elevation myocardial infarction (STEMI) and multivessel coronary artery disease (CAD) without cardiogenic shock. The present network meta-analysis investigated the optimal timing of MV-PCI in this context. METHODS: We pooled the aggregated data from randomized trials investigating stable STEMI patients with multivessel CAD treated with a strategy of either MV-PCI or culprit vessel-only PCI. The primary outcome was all-cause death. The main secondary outcomes were cardiovascular death, myocardial infarction, and unplanned ischemia-driven revascularization. RESULTS: Among 11 trials, a total of 10 507 patients were randomly assigned to MV-PCI (same sitting, n=1683; staged during the index hospitalization, n=3460; staged during a subsequent hospitalization within 45 days, n=3275) or to culprit vessel-only PCI (n=2089). The median follow-up was 18.6 months. In comparison with culprit vessel-only PCI, MV-PCI staged during the index hospitalization significantly reduced all-cause death (risk ratio, 0.73; 95%CI, 0.56-0.92; P=.008) and ranked as possibly the best treatment option for this outcome compared with all other strategies. In comparison with culprit vessel-only PCI, a MV-PCI reduced cardiovascular mortality without differences dependent on the timing of revascularization. MV-PCI within the index hospitalization, either in a single procedure or staged, significantly reduced myocardial infarction and unplanned ischemia-driven revascularization, with no significant difference between each other. CONCLUSIONS: In patients with STEMI and multivessel CAD without cardiogenic shock, multivessel PCI within the index hospitalization, either in a single procedure or staged, represents the safest and most efficacious approach. The different timings of multivessel PCI did not result in any significant differences in all-cause death. This study is registered at PROSPERO (CRD42023457794).

El principio ético de la intervención humana en la responsabilidad civil

Una de las mayores complejidades que se presentan respecto de la responsabilidad civil por daños causados por sistemas de inteligencia artificial viene dada por la dificultad de atribuir la conducta que causa daño a un sujeto particular. Frente a ello, este artículo expone la importancia del principio ético de la intervención humana para la responsabilidad civil, cuya función consiste en constituir la guía para la interpretación y aplicación de sus reglas en los casos en los que, como resultado de una acción u omisión emanada de una decisión, recomendación o predicción realizada por un sistema de inteligencia artificial, se causen daños a las personas.

One of the main challenges associated with regard to civil liability for damages resulting from artificial intelligence systems is the difficulty of attributing the behavior that led to harm to a specific individual. The aim of this article is to highlight the significance of the ethical principle of human intervention for civil liability. This principle serves as a guide for interpreting and applying rules when artificial intelligence systems cause harm to individuals due to actions, decisions, recommendations or predictions.

Partial-Cost Analysis and Economic Impact of Ambulatory Coronary Angioplasty in a Private Hospital in the Caribbean: Análisis Parcial de Costos e Impacto Económico de la Angioplastia Coronaria Ambulatoria en un Hospital Privado del Caribe.

OBJECTIVES: This study aimed to assess direct costs of percutaneous coronary intervention (PCI) without hospital admission versus PCI with hospital admission longer than 24 hours in a private hospital-institutional perspective in the Dominican Republic in 2022. METHODS: This study has a comparative approach based on a prospective cross-sectional partial-cost analysis. We evaluated the direct costs of 10 patients from PCI without hospital admission approach and 10 patients from a hospital admission longer than 24 hours as a control group. We used a "first-come-first-served" approach from December 2021 to March 2022. The analysis used the electronic invoice generated for each patient. RESULTS: PCI without hospital admission approach represents $472.56 in patient savings, equivalent to a cost reduction of 12.5%. The subcosts analysis showed the pharmacy section as the main driver of the overall cost difference. CONCLUSIONS: PCI without hospital admission was economically cost-saving compared with the control approach in direct costs in the Dominican perspective. The economic benefit is substantial and compliments the ease of use. This analysis may lead to improvements in institutional management of resources and can potentially be adapted to other health systems in the region.

Impact of previous percutaneous coronary intervention on angiographic and clinical outcomes in patients with ST-segment elevation myocardial infarction.

BACKGROUND: The prognosis of patients with ST-segment elevation myocardial infarction (STEMI) and previous percutaneous coronary intervention (PCI) is uncertain. OBJECTIVE: To evaluate if previous PCI in patients with STEMI increases the risk of major cardiovascular events, and if final epicardial blood flow differs according to the reperfusion strategy. MATERIAL AND METHODS: Observational, longitudinal, comparative sub-study of the PHASE-MX trial that included patients with STEMI and reperfusion within 12 hours of symptom onset, who were classified according to their history of PCI. The occurrence of the composite primary endpoint (cardiovascular death, re-infarction, congestive heart failure and cardiogenic shock) within 30 days was evaluated using Kaplan-Meier estimates, log-rank test and Cox proportional hazards model. Epicardial blood flow was assessed using the TIMI grading system after reperfusion. RESULTS: A total of 935 patients were included; 85.6% were males and 6.9% had a history of PCI; 53% underwent pharmacoinvasive therapy, and 47%, primary PCI. The incidence of the composite primary endpoint at 30 days in patients with a history of PCI was 9.8% vs 13.3% in those with no previous PCI (p = 0.06). Among the patients with previous PCI, 87.1% reached a final TIMI grade 3 flow after primary PCI vs. 75% in the group with pharmacoinvasive strategy (p = 0.235). CONCLUSIONS: A history of PCI does not increase the risk of major cardiovascular events at 30 days; however, it impacted negatively on the final angiographic blood flow of patients that received pharmacoinvasive therapy (compared to primary PCI).

ANTECEDENTES: El pronóstico de los pacientes con infarto agudo de miocardio con elevación del segmento ST (IAMCEST) y antecedente de intervención coronaria percutánea (ICP) es incierto. Objetivos: Evaluar si la ICP previa en pacientes con IAMCEST incrementa el riesgo de eventos cardiovasculares mayores y si el flujo final epicárdico varía según la estrategia de reperfusión. MATERIAL Y MÉTODOS: Subestudio de PHASE-MX, observacional, longitudinal y comparativo, de pacientes con IAMCEST reperfundidos en menos de 12 horas de iniciados los síntomas, divididos conforme el antecedente de ICP. El acaecimiento del criterio de valoración principal (muerte cardiovascular, reinfarto, insuficiencia cardíaca y choque cardiogénico) dentro de los 30 días se comparó con estimaciones de Kaplan-Meier, prueba de rangos logarítmicos y modelo de riesgos proporcionales de Cox. El flujo epicárdico final se evaluó con el sistema de clasificación del flujo TIMI después de la reperfusión. RESULTADOS: Se incluyeron 935 pacientes, 85.6 % del sexo masculino, 6.9 % de los cuales tenía antecedente de ICP; 53 % recibió terapia farmacoinvasiva y 47 %, ICP primaria. La incidencia del criterio de valoración principal en pacientes con ICP previa fue de 9.8 % versus 13.3 % en aquellos sin ese antecedente (p = 0.06); 87.1 % de los pacientes con ICP previa obtuvo flujo final de grado TIMI 3 versus 75 % del grupo con estrategia farmacoinvasiva (p = 0.235). CONCLUSIONES: El antecedente de ICP no incrementa el riesgo de eventos cardiovasculares mayores a los 30 días en pacientes con IAMCEST; sin embargo, impacta negativamente en el flujo sanguíneo angiográfico final de los pacientes que recibieron terapia farmacoinvasiva (en comparación con ICP primaria).

[Strategies for the prevention and non-pharmacological treatment of obesity. Models of care]. / Estrategias para la prevención y el tratamiento no farmacológico de la obesidad. Modelos de atención.

The prevalence of obesity has increased in recent years worldwide. In this context, strategies for management obesity in primary care are essential. The first step in the treatment of obesity are lifestyle intervention programs. The three pillars of these programs, ideally of high intensity (high frequency of visits), are dietary intervention, exercise and behavioral therapy. There is no universal model of care for patients with obesity, but it must take into account key aspects, such as facilitating the access and adherence of the patient and a multidisciplinary and coordinated care among professionals at different levels of healthcare. The components of the model of care and its format should be defined according to the resources available and the characteristics of the population to be treated.

Cardiogenic shock complicating acute myocardial infarction and multivessel disease: revascularization strategy according to ischemic territory.

INTRODUCTION AND OBJECTIVES: The association of revascularization strategy with clinical outcomes according to the ischemic territory of nonculprit lesion has not been documented in patients with acute myocardial infarction complicated by cardiogenic shock (AMI-CS). This study aimed to compare outcomes between culprit-only and immediate multivessel percutaneous coronary intervention (PCI) according to ischemic territory in patients with AMI-CS. METHODS: A total of 536 patients with AMI-CS and multivessel disease from the SMART-RESCUE registry were categorized according to ischemic territory (nonculprit left main/proximal left anterior descending artery [LM/pLAD] vs culprit LM/pLAD vs no LM/pLAD). The primary outcome was a patient-oriented composite endpoint (POCE) consisting of all-cause death, myocardial infarction, rehospitalization due to heart failure, or repeat revascularization at 1 year. RESULTS: Among the total population, 108 patients had nonculprit LM/pLAD, 228 patients had culprit LM/pLAD, and 200 patients had no LM/pLAD, with the risk of POCE being higher in patients with large ischemic territory lesions (53.6% vs 53.4% vs 39.6%; P = .02). Multivessel PCI was associated with a significantly lower risk of POCE compared with culprit-only PCI in patients with nonculprit LM/pLAD (40.7% vs 66.9%; HR, 0.52; 95%CI, 0.29-0.91; P=.02), but not in those with culprit LM/pLAD (P=.46) or no LM/pLAD (P=.47). A significant interaction existed between revascularization strategy and large nonculprit ischemic territory (P=.03). CONCLUSIONS: Large ischemic territory involvement was associated with worse clinical outcomes in patients with AMI-CS and multivessel disease. Immediate multivessel PCI might improve clinical outcomes in patients with a large nonculprit ischemic burden.

A pilot randomised control study to investigate the effect of the South African Adolescence Group Sleep Intervention (SAASI) on adolescent sleep and PTSD.

Background: Trauma exposure prevalence and consequent post-traumatic stress disorder among South African adolescents are significant. Sleep disturbances are among the most frequently reported difficulties faced by those dealing with PTSD. The current study examined the feasibility and preliminary efficacy of the South African Adolescence Group Sleep Intervention on PTSD symptom severity and sleep disturbance.Method: Sixty-one adolescents with PTSD diagnoses and sleep disturbance were randomly assigned (1:1) to one individual and four group sessions of a sleep intervention (SAASI) or a control group. Participants completed the Child PTSD symptom scale for DSM5 (CPSS-5) and the Pittsburgh Sleep Quality Index (PSQI) among other sleep and psychiatric measures. The trial was registered on the Pan African Trial Registry (PACTR202208559723690).Results: There was a significant but similar decrease in PSQI scores in both groups over time indicating no overall intervention effect (Wald test = -2.18, p = .029), mean slope = -0.2 (95% CI: -0.37 to -0.02) (p = .583). On the CPSS-5, interaction between groups was also not significant (p = .291). Despite this overall finding, the mean difference in CPSS-SR-5 scores increased over time, with the difference between groups post-treatment -9.10 (95%CI: -18.00 to -0.21), p = .045 and the 1-month follow-up contrast - 11.22 (95%CI: -22.43 to -0.03), p = .049 suggesting that PTSD symptom severity decreased more in the intervention group than the control group. The dropout rate was higher than expected for both the intervention (n = 10; 32%) and control (n = 8; 26.7%) groups. Dropout were mostly school commitments or travel related.Conclusions: Early findings suggest a trend towards dual improvement in sleep quality and PTSD symptom severity in adolescents with a sleep disturbance and PTSD receiving a group sleep intervention (SAASI). Further investigation in a properly powered RCT with detailed retention planning is indicated.

A four-week group sleep intervention seems feasible in adolescents with PTSD and sleep disturbances in a low-resource South African setting.Utilising less specialised mental health resources such as nurses and counsellors in intervention delivery was feasible and effective.Preliminary results are promising and support further research to establish the efficacy of the intervention.

Clinical impact of complex percutaneous coronary intervention in the pre-TAVR workup.

INTRODUCTION AND OBJECTIVES: In patients undergoing percutaneous coronary intervention (PCI) in the workup pre-transcatheter aortic valve replacement (TAVR), the clinical impact of coronary revascularization complexity remains unknown. This study sought to examine the impact of PCI complexity on clinical outcomes after TAVR in patients undergoing PCI in the preprocedural workup. METHODS: This was a multicenter study including consecutive patients scheduled for TAVR with concomitant significant coronary artery disease. Complex PCI was defined as having at least 1 of the following features: 3 vessels treated, ≥ 3 stents implanted, ≥ 3 lesions treated, bifurcation with 2 stents implanted, total stent length >60mm, or chronic total occlusion. The rates of major adverse cardiac events (MACE), including cardiovascular mortality, myocardial infarction, and coronary revascularization were evaluated. RESULTS: A total of 1550 patients were included, of which 454 (29.3%) underwent complex PCI in the pre-TAVR workup. After a median follow-up period of 2 [1-3] years after TAVR, the incidence of MACE was 9.6 events per 100 patients-years. Complex PCI significantly increased the risk of cardiac death (HR, 1.44; 95%CI, 1.01-2.07), nonperiprocedural myocardial infarction (HR, 1.52; 95%CI, 1.04-2.21), and coronary revascularization (HR, 2.46; 95%CI, 1.44-4.20). In addition, PCI complexity was identified as an independent predictor of MACE after TAVR (HR, 1.31; 95%CI, 1.01-1.71; P=.042). CONCLUSIONS: In TAVR candidates with significant coronary artery disease requiring percutaneous treatment, complex revascularization was associated with a higher risk of MACE. The degree of procedural complexity should be considered a strong determinant of prognosis in the PCI-TAVR population.

Promoción de la adherencia al tratamiento antihipertensivo a través de un servicio de atención farmacéutica apoyado en telefonía móvil / Promoting of Adherence to Antihypertensive Treatment through a Pharmaceutical Care Service Supported by Mobile Phones / Promoção da adesão ao tratamento anti-hipertensivo através de um serviço de assistência farmacêutica apoiado por telefonia móvel

ntroducción: la hipertensión arterial continúa siendo un desafío para la salud pública del Paraguay. La falta de adherencia a los tratamientos es un problema desde los puntos de vista médico, económico y psicosocial. Objetivo: promover la adherencia al tratamiento farmacológico antihipertensivo en pacientes con hiperten-sión que asisten a servicio de salud público, mediante un servicio de atención farmacéutica apoyado en el uso de telefonía móvil. Materiales y métodos: estudio cuasiexperimental en pacientes mayores de 18 años de ambos sexos con hipertensión arterial, en quienes se aplicaron intervenciones farmacéuticas apoyadas con el uso de telefonía móvil (llamada, mensajería sms y WhatsApp) y en quienes se evaluó la adherencia al tratamiento mediante el cuestionario de Morisky-Green, junto con preguntas complementarias para cono-cer las causas de no adherencia. Resultados: participaron 60 pacientes. Al inicio, el 68.3 % (n = 41) mostró adherencia al tratamiento según el cuestionario de Morisky-Green, y el 31.7 % (n = 19) no cumplió con la indicación. Después de las intervenciones se ha encontrado una mayor adherencia al tratamiento, al llegar al 96.7 % los cumplidores (p < 0.001). Entre las causas de no adherencia a la farmacoterapia están el olvido (28.3 %; n = 17), la falta de disponibilidad del medicamento en el hospital (20 %; n = 12) y el costo (10 %; n = 6). Conclusión: la utilización de telefonía móvil como apoyo a la atención farmacéutica podría constituirse en una herramienta para la promoción de la adherencia en pacientes con hipertensión arterial.

Introduction: Arterial hypertension remains a public health challenge in Paraguay; lack of adherence to treatment poses medical, economic, and psychosocial concerns. Information and communication tech-nologies (ICT) are valuable tools in monitoring patients and improving adherence to drug treatment. Objective: Promote adherence to antihypertensive drug treatment among hypertensive patients who attend a public health service by implementing a pharmaceutical care service supported by mobile phones. Materials and methods: A quasi-experimental study was conducted in male and female patients aged 18 years and older with arterial hypertension, in which pharmaceutical interventions supported by mobile telephony (calls, SMS messaging, and WhatsApp) were applied and adherence to treatment was assessed using the Morisky-Green questionnaire with complementary questions to identify the reasons for non-adherence. The research protocol was approved by a Research Ethics Committee of the FCQ-UNA (714/2021). Results: A total of 60 patients participated. Initially, 68.3% (n=41) showed adhe-rence to treatment according to the Morisky-Green questionnaire, while 31.7% (n=19) did not adhere to the indication. After the interventions, an increase in adherence to treatment was observed, with a compliance of 96.7% (p<0.001). Reasons non-adherence to pharmacotherapy included forgetfulness 28.3% (n=17), unavailability of drugs at the hospital 20% (n=12) and cost 10% (n=6).Conclusion: The use of mobile phones to support pharmaceutical care has the potential to serve as a tool for promoting adherence in patients with arterial hypertension

Introdução: A hipertensão arterial continua a ser um desafio para a saúde pública no Paraguai; a falta de adesão aos tratamentos é um problema do ponto de vista médico, econômico e psicossocial. Objetivo:Promover a adesão ao tratamento farmacológico anti-hipertensivo nos doentes com hipertensão que frequentam os serviços públicos de saúde, através de um serviço de assistência farmacêutica apoiado na utilização de telefonia móvel. Materiais e métodos: Estudo quase experimental realizado em pacientes maiores de 18 anos de ambos os sexos com hipertensão arterial; em que foram aplicadas intervenções farmacêuticas apoiadas no uso da telefonia móvel (chamada, mensagem sms e WhatsApp) e a adesão ao tratamento foi avaliada por meio do questionário Morisky-Green, juntamente com perguntas comple-mentares para determinar as causas da não adesão. Resultados. 60 pacientes participaram. No início, 68,3% (n = 41) apresentaram adesão ao tratamento conforme questionário de Morisky-Green e 31,7% (n = 19) não cumpriram a indicação. Após as intervenções constatou-se maior adesão ao tratamento, com adesão chegando a 96,7% (p < 0,001), as causas da não adesão à farmacoterapia foram esquecimento em 28,3% dos casos (n = 17), falta de disponibilidade de medicamentos no hospital 20% (n = 12) e custo 10% (n = 6). Conclusão: a utilização de telefonia móvel para apoio à assistência farmacêutica poderá tornar-se uma ferramenta para promover a adesão ao tratamento em pacientes com hipertensão.
