Caustic Ingestion: A Risk-Based Algorithm.

INTRODUCTION: Caustic ingestion management could be improved with a diagnostic approach based on risk factors. This study aimed to develop an algorithm derived from predictive factors of a poor clinical course, to evaluate its diagnostic accuracy and resource consumption, and to compare it with 2 other approaches, a radiological one based on computed tomography and a classical one based on symptoms and endoscopy. METHODS: All patients older than 15 years presenting with caustic ingestion in our tertiary care hospital between 1995 and 2021 were prospectively included. Adverse outcome was defined as intensive care unit admission, emergency surgery, or death. Ingestion characteristics, symptoms, and laboratory and endoscopic findings were analyzed to determine the most relevant risk factors. Diagnostic accuracy and the number of examinations required were estimated and compared with the other 2 algorithms applied to our series. RESULTS: The sample included 532 cases of caustic ingestion, 13.2% (95% confidence interval [CI]: 10.3-16.0) of which had adverse outcomes. Volume and type of caustic substance; presence of symptoms and pharyngolaryngeal involvement; and neutrophilia, acidosis, and endoscopic injury were combined to develop an algorithm that would provide the highest diagnostic odds ratio (167.2; 95% CI: 71.9-388.7). Following this approach, half of the patients (50.6%; 95% CI: 46.2-55.1) would not require any examination and, overall, the need for endoscopy (20.0%; 95% CI: 16.4-23.5) and computed tomography (16.3%; 95% CI: 13.0-19.5) would be lower than that for the other 2 algorithms. DISCUSSION: A risk-based algorithm could improve caustic ingestion management by maintaining high diagnostic accuracy while reducing diagnostic test requirements.

Caustic ingestion: development and validation of a prognostic score.

BACKGROUND: Caustic ingestion is a potentially severe condition and early identification of poor outcome is essential to improve management; however, prediction based on endoscopy alone can overestimate severity. This study aimed to develop and validate a prognostic score. METHODS: A prospective cohort study was designed to include all consecutive patients aged > 15 years who presented with caustic ingestion between 1995 and 2017. Adverse outcome was defined by intensive care unit admission, urgent surgery, or death. The predictive value of clinical, analytical, and endoscopic variables was assessed in the first cohort (derivation cohort) and a prognostic score based on the resulting risk factors was developed by logistic regression. Internal validation (bootstrapping) was performed and then external validation was checked in an independent sample of patients (validation cohort). RESULTS: 469 cases of caustic ingestion were included, 265 in the derivation cohort and 204 in the validation cohort. Ingestion of acidic substances (odds ratio [OR] 3.13, 95 % confidence interval [CI] 2.33 - 4.21), neutrophil count (OR 1.05, 95 %CI 1.04 - 1.06), metabolic acidosis (bicarbonate value, OR 0.82, 95 %CI 0.78 - 0.85), and endoscopic injury (OR 3.81, 95 %CI 3.35 - 4.34) were independent risk factors for poor outcome. The prognostic score based on these variables provided better accuracy than endoscopy alone (P = 0.04), with high sensitivity, specificity, positive and negative predictive values (93.3 %, 92.7 %, 72.7 %, 98.5 %, respectively), and area under the curve (0.976, 95 %CI 0.973 - 0.979; P < 0.001). CONCLUSIONS: This score allowed a reliable prognosis of caustic ingestion and was more accurate than endoscopy-based evaluation.

Clinical assessment of risk factors for infection in inflammatory bowel disease patients.

PURPOSE: Recognizing patients with inflammatory bowel disease who are prone to infection would enable the adjustment of the type and intensity of immunosuppressive treatment. The aim of this study was to identify a clinical profile of risk for infections in IBD patients, based on the interaction of immunosuppressive treatment with factors inherent to the patient. METHODS: A case-control study was performed among patients older than 18 years. Patients with any significant infection (any kind of severe or recurrent infection according to standard clinical criteria or a critical enough infection according to the patient) were defined as cases. Both cases and controls were randomly selected in a 1:3 ratio. All the period from diagnosis to the end of recruitment (June 2016) was analyzed. Risk factors for infection were identified by logistic regression analysis; the strength of association was reported by odds ratio (OR) with 95% confidence interval (95%CI). RESULTS: A total of 112 cases and 270 controls were included. The independent risk factors for significant infection are the number of immunosuppressants (one drug: OR 1.28, 95% CI 0.53-3.11, two drugs: OR 2.37, 95% CI 1.01-5,56, and three drugs: OR 5.84, 95% CI 1.57-21.72), body mass index (OR 1.08; 95 %CI 1,01-1,16), the degree of comorbidity (OR 1.52; 95% CI 1.04-2.21), and the intensity of inflammatory activity (OR 1.43; 95% CI 1.19-1.71). CONCLUSIONS: Regardless of immunosuppression, several patient factors such as comorbidity, body mass index, or the inflammatory activity of the disease determine the individual risk of infectious complications and should be considered for an adequate risk assessment.

Recommendations of the Spanish Association of Neurogastroenterology and Motility (ASENEM) to restart the activity of gastrintestinal motility laboratories after the state of alarm called due to the Covid-19 pandemic. / Recomendaciones de la Asociación Española de Neurogastroenterología y Motilidad (ASENEM) para el reinicio de la actividad de los laboratorios de motilidad digestiva, tras el confinamiento por el estado de alarma decretado a raíz de la pandemia por COVID-19.

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) was responsible for the outbreak of the 2019 coronavirus disease (COVID-19), which is now considered as a pandemic. The prevention strategies adopted have included social distancing measures and the modification, reduction or interruption of a large proportion of routine healthcare activity. This has had a significant impact on the care provided in Gastrointestinal Motility Units. Having passed the peak, in terms of mortality and infections, a gradual reduction in transmission figures has been observed in Spain and other European countries. The risk of reactivation, however, remains high, so it is necessary to have a plan in place that allows healthcare centres to safely resume, for their patients and professionals, instrumental examinations linked to the management of motor pathology. Based on the available scientific evidence and the consensus of a panel of experts, the Spanish Association of Neurogastroenterology and Motility (ASENEM) has drawn up a series of practical recommendations, which have been adapted to the risks inherent in each activity. These include individual protection proposals, as well as organisational and structural measures, which are conceived to allow for the gradual resumption of examinations while minimising the possibility of contagion.

[Infective endocarditis in adult patients with congenital heart disease. Experience from a reference centre]. / Endocarditis infecciosa en adultos con cardiopatía congénita. Experiencia en un centro de referencia.

INTRODUCTION: A growing number of patients with congenital heart disease (CHD) will reach adulthood. Infective endocarditis (IE) is a major complication in this population. The aim of this study was to describe the features of IE in adults with CHD treated in a reference centre. METHODS: A retrospective review was performed on a cohort of patients over 16 years of age with CHD who presented with IE (defined by the modified Duke criteria) between 1996 and 2014. Only the first episode from each patient was considered for the descriptive analysis. RESULTS: IE was observed in 27 patients. The median age at diagnosis of IE was 27.7 years, and 63% were male. Comorbidity was low (median Charlson index was 0). IE was mostly community-acquired (78%). The most frequent CHD were ventricular septal defect (33%). A repair was performed in 48% of patients, and 19% received palliative treatment. Forty-one percent of patients had some type of prosthesis. A residual defect was observed in 81%. The IE was detected in the right side of 44% of the patients. The most frequent aetiological agents were viridans group streptococci (41%) and Staphylococcus epidermidis (30%). Surgery was required to treat IE in 37% of patients. There were five re-infections and three relapses. Two patients died, both as a result of recurrence. CONCLUSIONS: IE in adults with CHD occurred in young patients, and almost all of them carried some prosthetic material or a residual defect. The IE is frequently right-sided. Although surgical treatment was required in many cases, mortality was low, except in the case of relapses.

Predictors of cardiovascular outcomes after surgery in severe tricuspid regurgitation: clinical, imaging and hemodynamic prospective study.

INTRODUCTION AND OBJECTIVES: Severe tricuspid regurgitation (TR) is a prevalent valve disease with a high mortality rate. Current guidelines do not define specific thresholds at which patients should be considered for surgery or percutaneous procedures. Thus, patients are usually referred for intervention at a late stage of the disease. This study aimed to assess predictors of cardiovascular outcomes in a prospective cohort of patients with severe TR referred for surgery. METHODS: This was an observational, prospective, nonrandomized study. All patients underwent surgery for severe TR based on current clinical guidelines. Complete anamnesis, blood test, echocardiogram, cardiovascular magnetic resonance and right and left catheterization were performed. Patients were followed up in the outpatient department and a combined endpoint (hospitalization for heart failure and cardiovascular mortality) was registered. RESULTS: Forty-three consecutive patients were included (age: 66.9 ± 9.6 years, 67.4% female). Tricuspid annuloplasty was performed in all patients. After a median follow-up of 38 months, 12 patients (27.9%) showed the combined endpoint and 7 (16.3%) died. Above all clinical, blood and imaging data, the indexed right ventricular end-diastolic volume constituted the best predictor of the combined endpoint (HR, 1.1; P = .02) and cardiovascular mortality (HR, 1.1; P = .05). Furthermore, indexed right ventricular end-diastolic volume was associated with TR recurrence after surgery, with no impact on clinical outcomes. CONCLUSIONS: In patients with severe TR referred for surgery, right ventricular remodeling assessed by cardiovascular magnetic resonance constituted the best independent predictor of cardiovascular outcomes at follow-up.

Epidemiology of infective endocarditis in Spain in the last 20 years.

Infective endocarditis is an uncommon disease, with an estimated incidence of 3.1 to 3.7 episodes per 100 000 inhabitants/year. The incidence is highest in elderly people. The microorganisms most frequently isolated in infective endocarditis are staphylococci and streptococci. In the last few decades, the spectrum of heart diseases predisposing to infective endocarditis has changed, since degenerative heart disease is the most common valve disease, and there are an increasing number of infective endocarditis patients without previously known valve disease. In addition, up to one-third of infective endocarditis patients become infected through contact with the health system. These patients are more frail, which leads to higher in-hospital mortality. As a result of substantial epidemiological changes, few cases of infective endocarditis can be prevented by antibiotic prophylaxis. Despite advances in medical and surgical treatment, in-hospital mortality among infective endocarditis patients is high. Nevertheless, there is room for improvement in reducing the rate of nosocomial bacteremia, the prompt diagnosis of infective endocarditis in at-risk patients, and the early identification of patients with a highest risk of complications, as well as in the creation of multidisciplinary teams for the management of this disease.
