Observed-to-expected lung-area-to-head-circumference ratio on ultrasound examination vs total fetal lung volume on magnetic resonance imaging in prediction of survival in fetuses with left-sided diaphragmatic hernia.

OBJECTIVE: To assess and compare the value of antenatally determined observed-to-expected (O/E) lung-area-to-head-circumference ratio (LHR) on ultrasound examination vs O/E total fetal lung volume (TFLV) on MRI examination to predict postnatal survival of fetuses with isolated, expectantly managed left-sided congenital diaphragmatic hernia (CDH). METHODS: This was a multicenter retrospective study including all consecutive fetuses with isolated CDH that were managed expectantly in Mannheim, Germany, and in five other European centers, that underwent at least one ultrasound examination for measurement of O/E-LHR and one MRI scan for measurement of O/E-TFLV during pregnancy. All MRI data were centralized, and lung volumes were measured by two experienced operators blinded to the pre- and postnatal data. Multiple logistic regression analyses were performed to examine the effect on survival at hospital discharge of various perinatal variables, including the center of management. In left-sided CDH with intrathoracic herniation of the liver, receiver-operating-characteristics (ROC) curves were constructed separately for cases from Mannheim and the other five European centers and were used to compare O/E-TFLV and O/E-LHR in the prediction of postnatal survival. RESULTS: From Mannheim, 309 patients were included with a median gestational age (GA) at ultrasound examination of 29.6 (range, 19.7-39.1) weeks and median GA at MRI examination of 31.1 (range, 18.0-39.9) weeks. From the other five European centers, 116 patients were included with a median GA at ultrasound examination of 26.7 (range, 20.6-37.6) weeks and median GA at MRI examination of 27.7 (range, 21.3-37.9) weeks. Regression analysis demonstrated that the survival rates at discharge were lower in left-sided CDH (odds ratio (OR), 0.349 (95% CI, 0.133-0.918), P = 0.033) and those with intrathoracic liver (OR, 0.297 (95% CI, 0.141-0.628), P = 0.001), and higher with increasing O/E-TFLV (OR, 1.123 (95% CI, 1.079-1.170), P < 0.001), advanced GA at birth (OR, 1.294 (95% CI, 1.055-1.588), P = 0.013) and when birth occurred in Mannheim (OR, 7.560 (95% CI, 3.368-16.967), P < 0.001). Given the difference in survival rate between Mannheim and the five other European centers, ROC curve comparisons between the two imaging modalities were presented separately. For cases of left-sided CDH with intrathoracic herniation of the liver, pairwise comparison showed no significant difference between the area under the ROC curves for the prediction of postnatal survival between O/E-TFLV and O/E-LHR in Mannheim (mean difference = 0.025, P = 0.610, standard error = 0.050), whereas there was a significant difference in the other European centers studied (mean difference = 0.056, P = 0.033, standard error = 0.056). CONCLUSIONS: In fetuses with left-sided CDH and intrathoracic herniation of the liver, the predictive value for postnatal survival of O/E-TFLV on MRI examination and O/E-LHR on ultrasound examination was similar in one center (Mannheim), but O/E-TFLV had better predictive value compared to O/E-LHR in the five other European centers. Hence, in these five European centers, MRI should be included in the diagnostic process for left-sided CDH. © 2024 International Society of Ultrasound in Obstetrics and Gynecology.

A randomised study comparing performance and safety of Eyestil Plus® vs Vismed Multi® in moderate-to-severe dry eye syndrome patients.

PURPOSE: This clinical investigation compared the performance and safety of Eyestil Plus® (SIFI) and Vismed Multi® (TRB Chemedica) for reducing keratitis lesions in moderate-to-severe dry eye disease (DED) patients. MATERIALS AND METHODS: This was a randomised, double-blind, multicentre investigation. 96 adults (>18 years of age) with moderate-to-severe DED received Eyestil Plus® (N = 48) or Vismed Multi® (n = 48) 6 times daily for 3 months. The primary objective clinical performance after 1 month as global corneal and conjunctival staining scores. The secondary objectives were clinical performance after 3 months, tear film stability (tear break up time (TBUT), tear production (Schirmer test), patient-reported outcomes (PROs), investigator satisfaction, and safety. RESULTS: 96 participants were randomised to receive the clinical investigations' treatments, 82.3% of them were female and their mean age was 65.8 years. The non-inferiority of Eyestil Plus® for moderate-to-severe DED was demonstrated at 1 month. No statistical difference was found for any of the study's objectives: change at 1 and 3 months of the global corneal and conjunctival staining score (p-value = 0.506 and 0.661, respectively), change at 1 and 3 months (p-value = 0.538 and 0.302) for TBUT test; change at 3 months for Schirmer test (p-value = 0.540). There were no changes for PROs either. Investigator satisfaction was high for both products. 16.6% of the participants experienced adverse events. CONCLUSION: This clinical investigation showed the non-inferiority of Eyestil Plus® compared to Vismed Multi® regarding performance and safety in a moderate-to-severe DED population.

Large-scale analysis of structural brain asymmetries during neurodevelopment: Associations with age and sex in 4265 children and adolescents.

Only a small number of studies have assessed structural differences between the two hemispheres during childhood and adolescence. However, the existing findings lack consistency or are restricted to a particular brain region, a specific brain feature, or a relatively narrow age range. Here, we investigated associations between brain asymmetry and age as well as sex in one of the largest pediatric samples to date (n = 4265), aged 1-18 years, scanned at 69 sites participating in the ENIGMA (Enhancing NeuroImaging Genetics through Meta-Analysis) consortium. Our study revealed that significant brain asymmetries already exist in childhood, but their magnitude and direction depend on the brain region examined and the morphometric measurement used (cortical volume or thickness, regional surface area, or subcortical volume). With respect to effects of age, some asymmetries became weaker over time while others became stronger; sometimes they even reversed direction. With respect to sex differences, the total number of regions exhibiting significant asymmetries was larger in females than in males, while the total number of measurements indicating significant asymmetries was larger in males (as we obtained more than one measurement per cortical region). The magnitude of the significant asymmetries was also greater in males. However, effect sizes for both age effects and sex differences were small. Taken together, these findings suggest that cerebral asymmetries are an inherent organizational pattern of the brain that manifests early in life. Overall, brain asymmetry appears to be relatively stable throughout childhood and adolescence, with some differential effects in males and females.

Post-traumatic retinal siderosis, a case report.

A thirty-year-old patient attended a few hours after an ocular trauma while hammering, receiving trauma with a metal splinter at the left eye. Due to an unfavorable clinical picture, surgical management was decided, which was initially rejected by the patient. He returned six months later with a profound decrease in left eye visual acuity, reaching counting finger at one meter despite optical correction. The anterior segment shows a lower scarring leukoma, associated with Tyndall (++), retrokeratic pigment, lower posterior synechiae and a total cataract. Cataract surgery with intraocular lens implantation and a posterior vitrectomy with intraocular foreign body extraction were indicated. At postoperative control it was shown that post-traumatic ocular siderosis did not significantly affect his central vision, which remains until now.

Clinical and economic burden of acute exacerbations of idiopathic pulmonary fibrosis: a prospective observational study in Spain (OASIS study).

BACKGROUND: Idiopathic pulmonary fibrosis (IPF) is a fatal progressive lung disease entailing significant impairment in health-related quality of life (HRQoL) and high socioeconomic burden. The course of IPF includes episodes of acute exacerbations (AE-IPF) leading to poor outcomes. This study aimed to compare management, costs and HRQoL of patients with AE-IPF to patients without AE-IPF during one year in Spain. MATERIALS AND METHODS: In a 12-month, prospective, observational, multicenter study of IPF patients, healthcare resource use was recorded and costs related to AE-IPF were estimated and compared between patients with and without AE-IPF. HRQoL was measured with the St. George's Respiratory Questionnaire (SGRQ), EuroQoL 5 dimensions 5 levels questionnaire (EQ-5D-5L), EQ-5D visual analogue scale (EQ-VAS) and the Barthel Index. RESULTS: 204 IPF patients were included: 22 (10.8%) experienced ≥ 1 acute exacerbation, and 182 (89.2%) did not. Patients with exacerbations required more primary care visits, nursing home visits, emergency visits, hospital admissions, pharmacological treatments and transport use (p < 0.05 for all comparisons). Likewise, patients with exacerbations showed higher annual direct health AE-IPF-related costs. In particular, specialized visits, emergency visits, days of hospitalization, tests, palliative care, transport in ambulance and economic aid (p < 0.05 for all comparisons). Exploratory results showed that patients with AE-IPF reported a non-significant but substantial decline of HRQoL compared with patients without AE-IPF, although causality can be inferred. CONCLUSION: We observed significantly higher resource use and cost consumption and lower HRQoL among patients suffering exacerbations during the study. Thus, preventing or avoiding AE-IPF is key in IPF management.

Effectiveness of handheld near infrared spectrometer for traceability of Angus steaks.

The feasibility of Near Infrared Spectroscopy was assessed for aging traceability of steaks of Angus beef (Biceps femoris) individually vacuum-packaged, as well as for the prediction of the refrigeration storage time (0, 7, and 14 days). For this purpose, a total of 288 steaks homogeneously distributed among the sampling times were used. The model developed by Partial Least Squares-Discriminant Analysis offered high discrimination ability between aged beef vs. non-aged. The accuracy after external validation exceeded 90%. Regarding the predictive capacity of the storage time, it was greater on the set of aged samples, in which the accuracy achieved values higher than 96%, while the accuracy decreased to 75% for the non-aged samples. Results obtained support the ability of NIRS technology to be considered in any digital transformation strategy for traceability across the meat supply chain.

Comparison of water- vs. land-based exercise for improving functional capacity and quality of life in patients living with and beyond breast cancer (the AQUA-FiT study): a randomized controlled trial.

BACKGROUND: Patients living with and beyond breast cancer frequently exhibit several side effects that can impact quality of life and physical functioning way beyond diagnosis and cancer therapies. Traditional on-land exercise has shown to be effective in reducing several symptoms of BC but little is known about the role of water-based exercise in improving physical and psychological well-being. OBJECTIVES: To compare land- vs. water-based exercise training for BC survivors to improve Health-Related Quality of Life (HRQoL), cancer-related fatigue (CRF), physical functioning, body composition and physical activity in patients with BC. METHODS: A randomised, parallel group (1:1) controlled trial was conducted between 2020 and 2022. Patients were randomly allocated to complete a similar exercise training twice weekly during 12 weeks either on land (LG) using traditional gym equipment or in a swimming pool (WG) using body-weight exercises and water-suitable accessories. Both groups were supervised and monitored by an experienced physiotherapist. Main outcome was HRQoL (EORTC QLQ C30 and B23 module) and CRF measured with the Piper Scale. Secondary variables included functional capacity with the 6 Minutes Walking Test (6MWT), upper and lower body strength (handgrip strength and 30″ Sit-to-Stand (STS) test), body composition and objectively measured physical activity. RESULTS: 28 patients were assessed and randomised during the study period. One patient did not receive the allocated intervention due to skin issues and one patient was dropped out during the intervention. A significant effect of time was found for both symptom severity (F(2,52) = 6.46, p = 0.003) and overall functioning (F1.67,43.45 = 5.215, p =0 .013) but no interaction was found between group and time. No effects were reported for CRF. Similar findings were reported for functional capacity (time effect F1.231,32.019 = 16.818, p < 0.001) and lower body strength (time effect F2,52 = 15.120, p < 0.001) as well as fat mass (time effect F2,52 = 4.38, p = 0.017). Notably, a significant time per group interaction was reported for physical activity (F2,52 = 6.349, p =0.003) with patients in the WG significantly improving PA levels over time while patients in the LG exhibited a marked decreased. CONCLUSIONS: Exercise training either in water or on land can decrease symptom severity and improve functionality and body composition. Water-based training seems more effecting than land-based exercise to improve physical activity patterns over time.

Dependency and frailty in the older haemodialysis patient.

BACKGROUND: Frailty among older adults undergoing hemodialysis is increasingly prevalent, significantly impacting cognitive function, mobility, and social engagement. This study focuses on the clinical profiles of very older adults in hemodialysis, particularly examining the interplay of dependency and frailty, and their influence on dialysis regimens. METHODS: In this observational, descriptive study, 107 patients aged over 75 from four outpatient centers and one hospital unit were examined over a year. Patient data encompassed sociodemographic factors, dialysis specifics, analytical outcomes, lifestyle elements, and self-reported post-treatment fatigue. Malnutrition-inflammation scale was used to measure the Nutritional status; MIS scale for malnutrition-inflammation, Barthel index for dependency, Charlson comorbidity index; FRIED scale for frailty and the SF12 quality of life measure. RESULTS: The study unveiled that a substantial number of older adults on hemodialysis faced malnutrition (55%), dependency (21%), frailty (46%), and diminished quality of life (57%). Patients with dependency were distinctively marked by higher comorbidity, severe malnutrition, enhanced frailty, nursing home residency, dependency on ambulance transportation, and significantly limited mobility, with 77% unable to walk. Notably, 56% of participants experienced considerable post-dialysis fatigue, correlating with higher comorbidity, increased dependency, and poorer quality of life. Despite varying clinical conditions, dialysis patterns were consistent across the patient cohort. CONCLUSIONS: The older adult cohort, averaging over four years on hemodialysis, exhibited high rates of comorbidity, frailty, and dependency, necessitating substantial support in transport and living arrangements. A third of these patients lacked residual urine output, yet their dialysis regimen mirrored those with preserved output. The study underscores the imperative for tailored therapeutic strategies to mitigate dependency, preserve residual renal function, and alleviate post-dialysis fatigue, ultimately enhancing the physical quality of life for these patients.

Progressive supranuclear palsy, a case report.

Progressive Supranuclear Palsy (PSP), also known as Steele-Richardson-Olszewski syndrome, is a rare neurodegenerative disease characterized by a variety of motor and neuro-ophthalmological symptoms. We present the case of a 73-year-old male patient with a history of type 2 diabetes and high blood pressure, who consulted for gait disorders, tremors in the extremities, and difficulty controlling conjugate gaze. During physical examination, findings consistent with PSP were noted, including hypomimia, muscle rigidity, and abnormal movements. The initial misdiagnosis of Parkinson's disease and subsequent administration of levodopa highlight the importance of accurate diagnosis in complex neurological conditions. This clinical case highlights the need for a thorough evaluation of neuro-ophthalmological symptoms and signs to ensure an appropriate therapeutic approach and improve the quality of life of patients.

Clinical and Surgical Outcomes of Endoscopic Endonasal Approach for Giant Pituitary Adenomas: Analysis of Predictive Factors.

BACKGROUND: Giant pituitary adenomas (GPAs) are defined as tumors with ≥40 mm in any maximum diameter, and these tend to invade multiple intracranial compartments. Hence, treatment remains a surgical challenge. OBJECTIVE: To describe the clinical and surgical outcomes of the endoscopic endonasal approach (EEA) for GPA in a pituitary referral center in Latin America and to analyze associated predictive factors. METHODS: 37 patients with histologically-confirmed GPA treated solely through the EEA between a 2-year period were included. Preoperative and postoperative clinical and neuroimaging findings; surgical morbidity and mortality; and binary logistic regression analysis to assess predictive factors were analyzed. RESULTS: Preoperative visual impairment prevalence was 97.3%. Mean tumor volume was 32 cc and gross total resection rate was 40.5%. Favorable visual acuity and visual fields outcome rate was 75% and 82.9%, respectively. In the multivariate analysis, bilateral cavernous sinus invasion (P = 0.018) and postoperative cerebrospinal fluid (CSF) leak (P = 0.036) were associated with an unfavorable visual acuity outcome, while radiation therapy (P = 0.035) was for visual fields. Similarly, intraoperative CSF leak was a predictive factor for postoperative CSF leak (10.8%) (P = 0.042) and vascular injury (13.5%) (P = 0.048). CONCLUSIONS: In this first Mexican clinical series, we demonstrated that the EEA is a safe and effective technique for GPA, although early diagnosis and prompt intervention may promote further visual function preservation without significant endocrine morbidity.

DNA barcoding of the genus Apaidia Hampson, 1900 for species delimitation from Western Mediterranean fauna (Lepidoptera, Erebidae).

The genus Apaidia Hampson, 1900 is a relict Western Mediterranean genus in the South-western part of Europe and the North-western areas of the Mediterranean Africa comprising so far three species, Apaidia rufeola (Rambur, 1832), Apaidia mesogona (Godart, [1824]) and Apaidia barbarica Legrand, 1939. According to the examined material, COI mitochondrial DNA sequences and adult morphology integration supports the existence of three main lineages of Apaidia with sequence divergence rates of approximately 4.5%, which are within the range reported for other well-defined insect species. In addition, we recovered three different BINS, suggesting the presence of different species with unique and specific identifier for A. mesogona (AEC6797), A. rufeola (AEI9539), and the Iberian-Balearic A. barbarica (AEI9540). This study contributes to a better understanding of the taxonomy of the genus Apaidia and challenges future revision of this genus in Northern Africa, as well as the presence of the Apaidia species in Western Mediterranean islands and populations located in Italy.

Online Cognitive-Behavioral Intervention on Adherence and Quality of Life in Elderly Adults with Diabetes: Two cases study

During the COVID-19 pandemic, elderly adults with type 2 diabetes mellitus (T2DM) have experienced difficulties to adhere to their therapy (TA), a situation which not only has had an impact on their glycemic control, but on their quality of life (QoL) as well. Telepsychology has proved to be an effective alternative to treat health-related complications in patients with this disease, however, results of same are unknown among the Latin American population. The aim of this study was determining the effect of Online Cognitive-Behavioral Therapy on TA, overall QoL and specific QoL in two elderly adults with T2DM. The case of a 62-year-old woman and a 60-year-old man who was offered an intervention consisting of nine sessions offered through a video conference platform is presented. The procedure included: psychoeducation, self-control training techniques, behavior reinforcement, feedback and problem solving. The Objective Clinical Change (OCC) evidences an increase in TA behaviors, such as use of medications, following a healthy diet (OCC≥ 0.20) and monitoring capillary blood glucose in the medium term (four months). Likewise, improve specific QoL for T2DM patients (OCC≤ -0.20). It is concluded that telepsychology is a low-cost, safe, feasible and effective type of therapy to increase and maintain TA behaviors, as well as to improve the QoL of patients suffering T2DM. Even though, more research is needed to increase the effectiveness of this therapy modality (AU)

Oclusión de la arteria central de la retina como complicación oftalmológica luego de un accidente ofídico / Central retinal artery occlusion as an ophthalmic complication after snakebite

La mordedura de serpiente causa entre 421.000-1.200.000 envenenamientos anuales con múltiples trastornos sistémicos secundarios a hematotoxicidad, neurotoxicidad y vasculotoxicidad siendo raras las manifestaciones oftalmológicas secundarias a mordedura de serpiente. La familia de serpientes Viperidae, causa más frecuentemente manifestaciones oftalmológicas como el infarto macular, el glaucoma crónico de ángulo abierto y la hemorragia retiniana o vítrea. La oclusión de la arteria central de la retina es una complicación ocular extremadamente rara. Reportamos el caso de una paciente de 30 años de edad, que consultó por mala visión del ojo izquierdo semanas después de sufrir una mordedura de serpiente (Bothrops atrox) en el miembro inferior izquierdo. Se diagnosticó de una oclusión de la arteria central de la retina con hallazgos anormales en el examen físico oftalmológico y en pruebas complementarias retinianas y neurooftalmológicas (AU)

Snakebite causes 421,000 - 1,200,000 poisonings per year due to hematotoxicity, neurotoxicity and vasculotoxicity. Ophthalmological manifestations secondary to snake bites are rare. If the snake belongs to the Viperidae family, the most frequent ophthalmologic manifestations are macular infarction, chronic open-angle glaucoma, and retinal or vitreous hemorrhage. Central retinal artery occlusion is an extremely rare ocular complication. We report the case of a 30-year-old patient, who consulted due to poor vision in her left eye weeks after suffering a snake bite (Bothrops atrox) in her left lower limb. The diagnosis was a central retinal artery occlusion in the left eye with abnormal findings in the ophthalmological physical examination and in complementary retinal and neuro-ophthalmological tests (AU)

Tendencia de la hospitalización por ictus isquémico en adultos jóvenes de la Región de Murcia durante el periodo 2006-2014 / Trends in hospitalisation for ischaemic stroke in young adults in the region of Murcia (Spain) between 2006 and 2014

Introducción: Estudios recientes en Europa y Estados Unidos muestran un posible aumento de la incidencia y la hospitalización por ictus isquémico en adultos jóvenes, sin embargo, en España la información disponible de la tendencia es escasa. Por ello planteamos analizar la tendencia de hospitalización por ictus isquémico en adultos menores de 50 años en la Región de Murcia entre 2006 y 2014. Método: Se realizó un estudio retrospectivo de las altas de hospitalización por enfermedad cerebrovascular (ECV) extraídas del Registro del conjunto mínimo de datos al alta hospitalaria. Se obtuvieron las tasas estandarizadas, desagregadas según edad y subtipo de ECV. La tendencia de los episodios fue analizada mediante regresión de joinpoint, obteniendo la tasa estandarizada anual calculada y el porcentaje de cambio anual (PCA). Resultados: Se identificaron un total de 27.064 altas por ECV en los 9 años del estudio. Los episodios generados por ictus isquémico fueron los más numerosos (61,0%), en pacientes entre 18 y 49 años; entre los años extremos, se registró un aumento del 26% de los episodios por ictus isquémico y del 29,2% de las tasas, mientras que en la regresión de joinpoint no se observó tendencia (PCA = 2,74%, p ≥ 0,05). Por el contrario, en mayores de 49 años esta tendencia fue descendente (PCA = –1,24%, p < 0,05). Conclusiones: No se ha identificado una tendencia en la hospitalización por ictus isquémico en adultos jóvenes a pesar del descenso en adultos de mayor edad. Sería importante identificar las causas de este comportamiento desigual para desarrollar medidas específicas dirigidas al grupo de menor edad. (AU)

Introduction: Recent studies conducted in Europe and the United States suggest upward trends in both incidence and hospitalisation rates for ischaemic stroke in young adults; however, data for Spain are scarce. This study analyses the trend in hospitalisation due to ischaemic stroke in adults aged under 50 years in the region of Murcia between 2006 and 2014. Method: We performed a retrospective study of patients discharged after hospitalisation due to cerebrovascular disease (CVD); data were obtained from the regional registry of the Minimum Basic Data Set. Standardised rates were calculated, disaggregated by age and CVD subtype. Time trends were analysed using joinpoint regression to obtain the annual calculated standardised rate and the annual percentage of change (APC). Results: A total of 27 064 patients with CVD were discharged during the 9-year study period. Ischaemic stroke was the most frequent subtype (61.0%). In patients aged 18 to 49 years, the annual number of admissions due to ischaemic stroke increased by 26%, and rates by 29.2%; however, the joinpoint regression analysis showed no significant changes in the trend (APC = 2.74%, P≥.05). By contrast, a downward trend was identified in individuals older than 49 (APC = –1.24%, P<.05). Conclusions: No significant changes were observed in the rate of hospitalisation due to ischaemic stroke among young adults, despite the decline observed in older adults. Identifying the causes of these disparate trends may be beneficial to the development of specific measures targeting younger adults. (AU)

Identificación y cuantificación del efecto fin de semana y festivos en la atención del síndrome coronario agudo en el Sistema Nacional de Salud / The effect of weekends and public holidays on the care of acute coronary syndrome in the Spanish National Health System

Introducción y objetivos Analizar si el ingreso en fin de semana o festivo (IFSF), frente al ingreso en días laborables, influye en el tratamiento (angioplastia, intervención coronaria percutánea [ICP]) y los resultados (mortalidad hospitalaria) de los pacientes hospitalizados por síndrome coronario agudo en el Sistema Nacional de Salud. Métodos Estudio observacional retrospectivo de pacientes ingresados por infarto agudo de miocardio con elevación del segmento ST (IAMCEST) o con síndrome coronario agudo sin elevación del segmento ST (SCASEST) en los hospitales del Sistema Nacional de Salud durante el periodo 2003-2018. Resultados Se seleccionaron 438.987 episodios de IAMCEST y 486.565 de SCASEST, de los cuales fueron IFSF el 28,8 y el 26,1% respectivamente. El IFSF se mostraba como un factor de riesgo de mortalidad hospitalaria en los modelos ajustados por riesgo del IAMCEST (OR=1,05; IC95%, 1,03-1,08; p<0,001) y del SCASEST (OR=1,08; IC95%, 1,05-1,12; p <0,001). La tasa de ICP en el IAMCEST fue más de 2 puntos porcentuales mayor en los pacientes ingresados en días laborables durante el periodo 2003-2011 y similar o incluso más baja en 2012-2018, sin cambios significativos para el SCASEST. El IFSF se mostró como factor de riesgo estadísticamente significativo tanto para el IAMCEST como para el SCASEST. Conclusiones El IFSF puede aumentar el riesgo de muerte hospitalaria en un 5% (IAMCEST) y un 8% (SCASEST). La persistencia del riesgo de mayor mortalidad hospitalaria tras ajustar por la realización de ICP y las demás variables explicativas probablemente indique dficiencias en el tratamiento durante el fin de semana respecto de los días laborables (AU)

Introduction and objectives To analyze whether admission on weekends or public holidays (WHA) influences the management (performance of angioplasty, percutaneous coronary intervention [PCI]) and outcomes (in-hospital mortality) of patients hospitalized for acute coronary syndrome in the Spanish National Health System compared with admission on weekdays. Methods Retrospective observational study of patients admitted for ST-segment elevation myocardial infarction (STEMI) or for non–ST-segment elevation acute coronary syndrome (NSTEACS) in hospitals of the Spanish National Health system from 2003 to 2018. Results A total of 438 987 episodes of STEMI and 486 565 of NSTEACS were selected, of which 28.8% and 26.1% were WHA, respectively. Risk-adjusted models showed that WHA was a risk factor for in-hospital mortality in STEMI (OR, 1.05; 95%CI,1.03-1.08; P < .001) and in NSTEACS (OR, 1.08; 95%CI, 1.05-1.12; P < .001). The rate of PCI performance in STEMI was more than 2 percentage points higher in patients admitted on weekdays from 2003 to 2011 and was similar or even lower from 2012 to 2018, with no significant changes in NSTEACS. WHA was a statistically significant risk factor for both STEMI and NSTEACS. Conclusions WHA can increase the risk of in-hospital death by 5% (STEMI) and 8% (NSTEACS). The persistence of the risk of higher in-hospital mortality, after adjustment for the performance of PCI and other explanatory variables, probably indicates deficiencies in management during the weekend compared with weekdays (AU)
