Respiratory Complications Are the Main Predictors of 1-Year Mortality in Patients with Hip Fractures: The Results from the Alzira Retrospective Cohort Study.

Introduction: Hip fractures pose a significant challenge for older individuals given their high incidence and one-year mortality rate. The objective of this study was to identify the primary predictors of one-year mortality in older adults hospitalized for hip fractures. Methods: We conducted a retrospective cohort study involving adults aged 70 years or older who were admitted to the hospital for fragility hip fractures between 1 January 2014 and 31 December 2021. A total of 3229 patients were recruited, with 846 (26.2%) experiencing one-year mortality. Results: Respiratory complications (HR 2.42, 95%CI 1.42-4.14; p = 0.001) were the most significant predictors of one-year mortality, followed by hospital readmission (HR 1.96, 95%CI 1.66-2.32; p < 0.001), the male sex (HR 1.88, 95%CI 1.46-2.32; p < 0.001), cardiac complications (HR 1.88, 95%CI 1.46-2.32; p < 0.001), and a diagnosis of dementia at admission (HR 1.37, 95%CI 1.13-1.66; p = 0.001). The Charlson Index and the American Society of Anesthesiologists physical status classification system also significantly increased the mortality risk. Conversely, higher hemoglobin levels at admission and elevated albumin at discharge significantly reduced the mortality risk. Conclusions: The one-year mortality rate is substantial in older adults with hip fractures who are admitted to an orthogeriatric unit. The appropriate management of anemia, nutritional disorders, and comorbidity at admission and during the follow-up could potentially mitigate long-term mortality after hip fractures.

P057 How Distance Between Residence and Treatment Center Impact the Outcome of Patients With Inflammatory Bowel Disease at CMN 20.

BACKGROUND: Inflammatory bowel disease (IBD) affects an estimated 1.6 million people in the United States with at least 70,000 new cases per year. In the last 15 years an increase in frequency of IBD cases from 0.30 cases per 100,000 person-years to 1.83 cases per 100,000 person-years has been reported in Mexico. Variables such as early hospitalization at diagnosis, low hemoglobin levels, high values of C-reactive protein (CRP), fecal calprotectin concentration and absence of mucosal healing during evolution define the prognosis of these patients. However, the distance a patient must travel in order to reach a specialized treatment center can become an impediment for a correct diagnosis and treatment, severely impacting the clinical outcome of such patients. METHODS: Observational, cross-sectional, retrospective study. Objective: In patients with IBD, determine the impact of distance between the residence and specialized treatment center on the general clinical outcome. Variables analyzed: sex, age, disease duration, average travel time, distance in kilometers between place of residence and specialized treatment center, Crohn´s Disease (CD) or Ulcerative Colitis (UC), and their respective severity classification scores, as well as number of hospital readmissions per year. The results were evaluated with ANOVA tests, univariate analysis had a 95% confidence index and a significant "p" determined as p < 0.05. RESULTS: The study included 66 patients (45 UC and 21 CD). Mean age 51.15± 17.5 years. The distance between residence and hospital was calculated and classified into 3 quartiles based on proximity: 750km (quartile 3). There was a higher risk among patients in the most distant quartile for the use of biological therapy (OR, 2.20; 95% CI, 0.23- 20.55) and surgery (OR, 2.76, 95% CI 0.49- 15.48). We observed a clear relationship between the number of hospital readmission and the distance quartiles with a p = 0.0047. CONCLUSION: We observed an impact between the distance of residence and specialized treatment center over the patient's clinical outcome. More readmissions, greater disease activity scores, more use of biological therapy and surgery were observed in patients who had to travel more than 750km from their home to their specialized treatment center compared to the other travel quartiles, this with a p = 0.0047.

P061 Impact of Inflammatory Bowel Disease on sleep quality in a Mexican population attended in a referral center.

BACKGROUND: Sleep disorders occur recurrently in patients with inflammatory bowel disease (IBD). The relationship between poor sleep quality and IBD activity has been subject to scarce attention. Poor sleep quality could be considered a relevant extraintestinal manifestation and a potential marker of subclinical inflammation, which could increase the severity of inflammation and the risk of relapse, however, we do not have enough information to confirm this hypothesis. Objective: Describe the impact of IBD on the quality of sleep, in patients treated in a referral hospital. METHODS: Observational, analytical, and cross-sectional study. Patients with diagnosis of IBD treated at Centro Médico Nacional "20 de Noviembre" were evaluated. The Pittsburgh Sleep Quality Index (PSQI) was used to measure sleep quality. IBD activity was measured using the Harvey-Bradshaw index for Crohn's disease (CD) and the Mayo scale for Ulcerative Colitis (UC). RESULTS: A total of 51 patients were included, the Pittsburgh Sleep Index Questionnaire (PSQI) was performed, after informed consent was signed. Patients had a mean age of 52. Fifty five percent were female, 65% had UC. Biological therapy was administered to 70.5%. In CD 89% were in remission and 11% in moderate activity. In UC 48.5% were in remission, 45.5% had mild activity and 6% had moderate activity. Eighty percent of the patients did not use hypnotic drugs. Patients with UC in remission had a bad perception of sleep quality in 68%, quite good sleep quality in 18% and very good sleep quality in 12% with a PSQI of 10.5 ± 3.2. In patients with mild activity, the perception of sleep quality was very good in 6%, quite good in 46%, quite bad in 40% and very bad in 6%, with a PSQI of 8 ± 3.7. In patients with moderate activity, 100% had a rather bad perception of sleep quality with a PSQI of 11 ± 1.4. For CD in remission the perception of sleep was quite bad in 43%, quite good in 43%, very bad in 6% and very good in 6% with a PSQI of 9 ± 4.3. In patients with moderate activity 50% had a very bad sleep quality perception and 50% a fairly good sleep quality perception with a PSQI of 14 ± 4.2. CONCLUSION: In this study a statistically significant association was obtained between PSQI and the perception of sleep reported by the patients, with a p < 0.005. Further research is still needed to better characterize sleep disturbances in this population. Due to the sample size, a prospective, randomized study is required to confirm these findings. The present analysis has no conflict of interest.

P073 Diagnostic Outcome of Patients With Non-Specific Colitis.

BACKGROUND: Colitis describes inflammation in the colon and is classified into defined diseases: Inflammatory bowel disease (IBD), Microscopic colitis, Ischemic colitis and Infectious colitis. The clinical significance of non-specific colitis is unclear as there are limited analysis which report the issue. Notteghem et al. (1993) showed that of 104 patients with non-specific colitis, 52.3% had another episode of symptoms within 3 years. Of these patients 54% were diagnosed with ulcerative colitis, 33% with Crohn's disease, and 13% remained unclassified, suggesting that non-specific colitis could be undiagnosed IBD. The objective of this analysis is to determine the clinical course of non-specific colitis through colonoscopy and histologic findings. METHODS: Retrospective observational study with patients underwent colonoscopies during the period from 2009 to 2019, whose biopsies were reported as non-specific colitis. RESULTS: 24 patients (18 women and 6 men) with non-specific colitis undergoing follow-up by the Gastroenterology outpatient clinic were included. The most frequent indications for colonoscopy were abdominal pain (43.7%), blood in stools (26.8%), diarrhea (21.6%) and anemia (7.9%). The mean age was 56.5 years. During follow-up, patients had at least 2 colonoscopies and 4 biopsies per colonic segment. In the male population ascending colon cancer was later diagnosed in 16.7%, another 16.7% were diagnosed with nonspecific chronic ulcerative colitis, 33.3% with eosinophilic colitis, and the rest of the patients were diagnosed with non-specific colitis. From the female group, 5.6% had lymphocytic colitis, 5.6% eosinophilic colitis, 5.6% collagenous colitis, 5.6% Crohn's disease, 5.6% mixed irritable bowel syndrome, and the rest of the patients (72%) had biopsy report of non-specific colitis. CONCLUSIONS: All patients with a histopathological diagnosis of non-specific colitis underwent a second colonoscopy with biopsy, which resulted in a definitive diagnosis of Crohn's disease in 5.6% of women and Ulcerative Colitis in 16.7% of men. This study comes to show that there is an important subgroup of patients who are underdiagnosed. We suggest that patients with non-specific colitis reported on a histopathology report must continue their follow-up by a specialized ward.

¿Puede tener un papel la mascarilla laríngea en la práctica de la terapia electroconvulsiva? Un estudio piloto / Can the laryngeal mask play a role in electroconvulsive treatment? A pilot study

Introducción. Optimizar el control de la ventilación en el proceso anestésico de la terapia electroconvulsiva (TEC) puede ser una forma de mejorar la efectividad y la seguridad del tratamiento. Existen varios métodos para inducir una convulsión terapéutica adecuada en pacientes con enfermedad médica comórbida o en aquellos con elevado umbral convulsivo, aunque todos presentan alguna limitación. Un nuevo abordaje es la hiperventilación con mascarilla laríngea, que produce una mayor oxigenación e hipocapnia, disminuyendo el umbral convulsivo. Este hecho puede, hipotéticamente, servir para disminuir la energía necesaria para obtener una convulsión terapéutica adecuada. Material y métodos. Se ha realizado un estudio piloto aleatorizado y cruzado con 14 pacientes en TEC de mantenimiento, utilizando mascarilla laríngea versus mascarilla facial. Las sesiones de TEC con mascarilla facial se realizaron con la energía estándar, mientras que en las sesiones de TEC con mascarilla laríngea se disminuyó la energía en un 45%. Resultados. A pesar de la reducción del 45% en la energía aplicada con el uso de mascarilla laríngea, no se han encontrado diferencias significativas en la duración de la convulsión en ambos grupos. Conclusiones. Con estos resultados se podría proponer la ventilación con mascarilla laríngea como una alternativa para disminuir la energía aplicada sin repercutir en la duración de la crisis. Este es un estudio preliminar con una muestra pequeña, aunque abre nuevas líneas de investigación. Sería necesario aumentar la muestra y valorar otras medidas de calidad de las convulsiones en futuros estudios con el fin de estudiar sus efectos no solo en la dosis de energía necesaria, sino también en una posible mejora de la ventilación y una posible minimización de los potenciales efectos secundarios de la TEC, algo que sería relevante sobre todo en pacientes con comorbilidad médica (AU)

Introduction. Optimising ventilation control in the anaesthetic process of electroconvulsive therapy (ECT) can be a method for improving the effectiveness and safety of some treatments. There are several approaches for inducing adequate therapeutic seizures in patients with medical co-morbidity or in those with high seizure thresholds, although all of them present limitations. A new approach is hyperventilation with laryngeal mask, a method that improves oxygenation, achieves hypocapnia, and lowers seizure threshold. Thus, hyperventilation with laryngeal mask could, hypothetically, be useful to decrease the energy needed to obtain adequate therapeutic seizures. Material and methods. A randomized crossover study was conducted on 14 patients on maintenance ECT, using a laryngeal mask versus a facemask. When laryngeal masks were applied, the energy was reduced by 45% compared with the energy required when ventilated with facemasks (performed with standard dose). Results. The results of the study revealed that, despite a 45% energy reduction with laryngeal mask, there were no significant differences in seizure length in either group. Conclusions. These results prompt us to propose ventilation with laryngeal mask as an alternative to decrease energy applied without lowering seizure times. This is a preliminary study with a small sample, which opens new lines of research. Larger samples and other measurements of seizure adequacy are needed in future studies, in order to study possible improvements in ventilation and minimising adverse effects of ECT, especially in patients with medical co-morbidities (AU)
