Point-of-care Ultrasound Diagnosis of Gastric Outlet Obstruction Syndrome.

Gastric Outlet Obstruction (GOO) is a clinical syndrome characterized by postprandial vomiting, epigastric pain, and abdominal distension due to mechanical or motility disorders. The suspicion will mainly rely on abdominal radiological imaging (computed tomography, barium studies) that might not be widely available or even be contraindicated. We report a 65-year-old male who developed progressive epigastralgia, anorexia, and vomiting. Physical examination revealed mild abdominal distension and epigastric tenderness on deep palpation. With the presumptive diagnosis of gastric outlet obstruction, an abdominal point-of-care ultrasound (POCUS) was performed and showed impaired gastric emptying and a "target sign." A gastroscopic exploration confirmed inflammatory pyloric stenosis due to coexisting antral and duodenal ulcers. POCUS could play an essential role in the easy ultrasonographic diagnosis of gastroparesis, helping to differentiate from other causes of obstruction and even raise suspicion in the diagnosis of pyloric stenosis as a consequence of a GGO. POCUS may serve as a first-line imaging test that can raise suspicion of this difficult to diagnose and probably underreported disease.

Fidaxomicin monotherapy versus standard therapy combined with bezlotoxumab for treating patients with Clostridioides difficile infection at high risk of recurrence: a matched cohort study.

BACKGROUND: Both fidaxomicin and bezlotoxumab (used in combination with an antibiotic against Clostridioides difficile) achieve reductions in recurrence rates of C. difficile infection (CDI). However, the two strategies have never been compared. METHODS: Data from two retrospective cohorts of 'real-life' use of fidaxomicin and bezlotoxumab in combination with a standard anti-C. difficile antibiotic were used to compare the rates of recurrence of both strategies. Since the two cohorts were not identical, we used a propensity score analysis. RESULTS: Three hundred and two patients were included: 244 in the fidaxomicin cohort and 78 in the bezlotoxumab cohort. A history of renal failure or immunosuppression was more frequent in patients receiving bezlotoxumab (39.7% and 66.7% versus 26.6% and 38.9%; P = 0.03 and P < 0.001, respectively), but the severity and number of previous CDI episodes were similar in both cohorts. We observed that 19.3% of the patients in the fidaxomicin cohort experienced recurrence, compared with 14.1% in the bezlotoxumab cohort (OR 1.45; 95% CI 0.71-2.96; P = 0.29) but the difference remained non-significant after propensity score matching using previously defined variables (OR 1.24; 95% CI 0.50-3.07; P = 0.64). Moreover, the multivariate analysis did not show differences depending on the drug used. CONCLUSIONS: We observed that fidaxomicin and bezlotoxumab are prescribed in similar clinical scenarios, although those treated with bezlotoxumab have greater comorbidity. The proportion of recurrences was numerically lower in those treated with bezlotoxumab, although the propensity analysis did not find significant differences between the two drugs.

Impact of cardiovascular risk factors in antiphospholipid syndrome: an observational study from the Spanish national registry.

OBJECTIVES: To determine the burden and impact of cardiovascular risk factors (CRF) in antiphospholipid syndrome (APS) patients. METHODS: Analysis of the patients diagnosed with APS identified in the Spanish Hospital Discharge Database between 2016 and 2017. We analysed the admissions due to arterial (ATE) and venous thromboembolic events (VTE) and evaluated the incidence and the attributed risk of each CRF. RESULTS: 5424 admissions in patients diagnosed with APS were identified. 64.6% were women and the mean age was 54.6. The mortality rate was 3.1%. Overall, 35.8% of patients had hypertension, 14% were diabetic, 21.7% hypercholesterolaemic, 9.9% obese and 26.7% smokers. Thromboembolic events (67.9% arterial and 32.1% venous) accounted for 11.9% of admissions and 7.1% of deaths. Male sex (OR 1.83, 95% CI 1.41-2.21), cholesterol (OR 1.25, 95% CI 1.01-1.54) and smoking (OR 1.49, 95% CI 1.22-1.81) were independently associated with thromboembolic events. Meanwhile, patients with ATE were older (57 vs. 54.1 years p=0.033), and presented more secondary APS (17.1% vs. 10.6%, p=0.034), hypertension (47.7% vs. 33.5%, p=0.001), diabetes (16.9% vs. 9.6%, p=0.017), cholesterol (34.3% vs. 17.8%, p<0.001) and smoking habit (41.2% vs. 24%, p<0.001) when compared with VTE. Risk factors independently associated with ATE events were male sex (OR=1.61, 95% CI=1.30-2.03), hypertension (OR=1.30, 95% CI=1.03-1.64), cholesterol (OR=1.51, 95% CI=1.18-1.94) and smoking habit (OR=1.84, 95% CI=1.47-2.32), while VTE events were determined by male sex (OR=2.06, 95% CI=1.53-2.77) and obesity (OR=1.61, CI=1.02-2.52). CONCLUSIONS: Thromboembolic events in APS were in part determined by a high prevalence of CRF. The identification of distinct profiles may allow us to undertake a more personalised approach to reduce thromboembolic events and to individualise anticoagulant and antiplatelet therapy.

Real-life experience with fidaxomicin in Clostridioides difficile infection: a multicentre cohort study on 244 episodes.

The high cost of fidaxomicin has restricted its use despite the benefit of a lower Clostridioides difficile infection (CDI) recurrence rate at 4 weeks of follow-up. This short follow-up represents the main limitation of pivotal clinical trials of fidaxomicin, and some recent studies question its benefits over vancomycin. Moreover, the main risk factors of recurrence after treatment with fidaxomicin remain unknown. We designed a multicentre retrospective cohort study among four Spanish hospitals to assess the efficacy of fidaxomicin in real life and to investigate risk factors of fidaxomicin failure at weeks 8 and 12. Two-hundred forty-four patients were included. Fidaxomicin was used in 96 patients (39.3%) for a first episode of CDI, in 95 patients (38.9%) for a second episode, and in 53 patients (21.7%) for a third or subsequent episode. Patients treated with fidaxomicin in a first episode were younger (59.9 years vs 73.5 years), but they had more severe episodes (52.1% vs. 32.4%). The recurrence rates for patients treated in the first episode were 6.5% and 9.7% at weeks 8 and 12, respectively. Recurrence rates increased for patients treated at second or ulterior episodes (16.3% and 26.4% at week 8, respectively). Age greater than or equal to 85 years and having had a previous episode of CDI were identified as recurrence risk factors at weeks 8 and 12. We conclude that the outcomes with fidaxomicin in real life are at least as good as those observed in clinical trials despite a more demanding evaluation. Be it 85 years of age or older, and the use after a first episode appears to be independent factors of CDI recurrence after treatment with fidaxomicin.

Effective definition of low humoral response to Clostridioides difficile infection.

BACKGROUND: Determination of the humoral response to Clostridioides difficile (CD) toxins could be of great value in the management of patients with CD infection (CDI). METHODS: A prospective study was conducted on the clinical characteristics and humoral response in patients with CDI. Determination of ELISA IgG CD anti-toxin B (tgcBiomics, Germany) was performed. The following dilutions were planned for each patient, 1:100, 1: 200, 1: 400, 1: 800: 1: 1600. A significant concentration of antibody was considered to be present in each dilution if an optical density 0.2 units higher than the negative control of the technique was evident. RESULTS: Eighty-five patients were included during the study period, November 2018-February 2020. The median age was 73 years (interquartile range: 62.5-85 years), with female predominance (45 patients, 52.9%). Thirty-nine patients (45.9%) had a severe infection. Seven patients (8.2%) had suffered an episode of CDI in the previous three months. Seventeen patients (20%) had one or more recurrent episodes during the three-month follow-up: No patient died during admission or required surgery for severe-complicated infection. The incidence of recurrence in patients with no antibody detected at 1:400 dilution was 25.4% (16 patients) while it was 4.3% (one patient) in patients with antibody present at that dilution (p = 0.03). Liver cirrhosis was associated with higher humoral response against CD. CONCLUSIONS: Antibodies IgG CD anti-toxin B detection at a dilution of 1:400, using a B ELISA technique, effectively identified patients at increased risk of recurrence. This information could help assist in the management of patients.

Prevalence and impact of cerebrovascular risk factors in patients with giant cell arteritis: An observational study from the Spanish national registry.

OBJECTIVE: To assess the prevalence and impact of cerebrovascular risk factors (CRF) on cerebrovascular events (CVE) in patients with giant cell arteritis (GCA). METHODS: Analysis of the patients diagnosed with GCA identified in the Spanish Hospital Discharge Database between 2016 and 2018. RESULTS: 8,474 hospital admissions from patients diagnosed with GCA were identified. 3.4% of the admissions were motivated by CVE (stroke in 2.8% and transient ischemic attack in 0.6%). When compared with the admissions due to other causes, the patients who suffered from CVE presented a higher rate of male sex (36.2% vs 43.5%, p=0.007), hypertension (66.9% vs 74.4%, p=0.004), diabetes (27.6% vs 33.7%, p=0.016) and atherosclerosis (6.6% vs 10.2%, p=0.0.017). After adjustment, male sex (OR=1.35, 95% CI 1.06-1.72) and mainly hypertension (OR=1.44, 95% CI 1.11-1.90) were associated with a higher risk of CVE. CONCLUSION: Hypertension, along with male sex, was the strongest risk factor for cerebrovascular events in GCA patients. In these high-risk patients, antiplatelet therapy should be re-considered and evaluated in prospective studies.

Usefulness of the hemogram as a measure of clinical and serological activity in systemic lupus erythematosus.

Background and objectives: Systemic Lupus Erythematosus (SLE) follow-up is based on clinical, and analytical parameters. We aimed to determine the differences between the Neutrophil-to-lymphocyte ratio (NLR), Platelet-to-lymphocyte ratio (PLR) and Red blood cell distribution width (RDW) between SLE patients and healthy controls and to assess their association with anemia status, classical inflammatory biomarkers and cytokines, disease activity, SLE related factors and treatment received for SLE. Methods: Seventy-seven patients with SLE according to 2012 SLICC criteria and 80 healthy controls were included. Patients with SLE were classified in SLE with anemia (SLE-a) and SLE without anemia (SLE-na). Statistical analysis between SLE patients and controls and the association of serological and clinical activity markers with proposed hematological indices among SLE patients were performed. Results: RDW, NLR and PLR, were significantly higher in SLE patients than in healthy control group (p < 0.001), in SLE-a patients as compared to SLE-na (p < 0.0001) and were significantly associated with hypocomplementemia (p < 0.05). PLR was higher in active patients measured by SLEDAI-2K score and with longer disease duration (p < 0.05). RDW was associated with serological activity of the patients (p < 0.05) and was correlated with SLEDAI-2K and SLICC/ACR scores, hsCRP, D-dimer, fibrinogen, IL-6 and TNF as well as with corticosteroids intake (p = 0.05). A logistic regression analysis confirmed that after adjustment by age and hemoglobin values, RDW presented linear correlation with IL-6 levels (Beta-coefficient = 0.369, p = 0.003). Conclusion: NLR, PLR and RDW values suggest SLE serological and clinical activity. Given their availability, these markers not only could be useful tools to identify and monitor active SLE patients but whose application should be considered in inflammatory pathologies orchestrated by IL-6 and TNF.

Red blood cell distribution width as prognostic factor in sepsis: A new use for a classical parameter.

PURPOSE: To evaluate Red blood cell distribution width (RDW) as a sepsis prognostic biomarker. METHODS: 203 septic patients admitted to the ICU. Analysis of RDW dynamics, hospital mortality discrimination ability and the added value when incorporated to the SOFA, LODS, SAPS-II and APACHE-II scores using the AUC-ROC. RESULTS: Non-survivors presented higher RDW values during the first week after ICU admission (p = 0.048). Only SOFA and RDW were independently associated with mortality when adjusted by Charlson, immunosuppression, nosocomial infection, NEWS2, SAPS-II, septic shock and haemoglobin (p < 0.05). After adjustment, AUC-ROC was 0.827, 0.822, 0.824, 0.834 and 0.812 for each model including admission, 24, 48 and 72-h and 7-days RDW, respectively. When added to the scores, 24-h RDW and admission RDW improved their discrimination ability (SOFA AUC-ROC = 0.772 vs 0.812 SOFA + admission RDW, p = 0.041; LODS AUC-ROC = 0.687 vs 0.710, p = 0.002; SAPS-II AUC-ROC = 0.734 vs 0.785, p = 0.021; APACHE-II AUC-ROC = 0.672 vs 0.755, p = 0.003). Admission RDW with SOFA presented the better discrimination ability for mortality. CONCLUSION: RDW is an independent prognostic marker of death in septic patients admitted in the ICU that improves SOFA, LODS, APACHE-II and SAPS-II discrimination ability. This parameter could be incorporated to the prognostic scores as a marker of systemic dysfunction and dysregulated inflammatory response.

Serum cytokines to predict systemic lupus erythematosus clinical and serological activity.

We aimed to explore the role of interleukin (IL)-6, interferon-gamma (IFNγ), IL-10, and tumor necrosis factor (TNF) as predictors of systemic lupus erythematosus (SLE) clinical and serological activity, and their correlation with the treatment received. We performed a retrospective analysis of 77 patients with SLE according to the 2012 Systemic Lupus International Collaborative Clinics (SLICC) criteria. The outcomes were serological activity (SA), active disease (AD), complete remission (CR), the low-disease activity state (LDAS), and immunosuppressive treatment. SA was present in 17.1%, AD in 17.3%, CR in 13%, and LDAS in 64.9% of patients. IL-6 values were higher in patients in SA, in AD, in those receiving steroids alone, and in patients without CR or LDAS (p < 0.05). IFNγ was associated with anti-double stranded DNA (dsDNA) antibodies positivity and immunosuppression, whereas IL-10 values were higher in patients with CR (p < 0.05). The IL6-IFN product was able to predict anti-double stranded DNA (anti-dsDNA) antibodies positivity (area under the receiver operating characteristic curve [AUC-ROC] = 0.705, 95% confidence interval [CI] 0.563-0.847), SA (AUC-ROC = 0.720, 95% CI 0.542-0.899), AD (AUC-ROC = 0.701, 95% CI 0.520-0.882), steroid treatment (AUC-ROC = 0.751, 95% CI 0.622-0.879), and the absence of LDAS (AUC-ROC = 0.700, 95% CI 0.558-0.834). The IL6-IFN/IL10 ratio predicted AD (AUC-ROC = 0.742, 955 CI 0.540-0.944), steroid treatment (AUC-ROC = 0.721, 95% CI 0.572-0.870), and the absence of LDAS (AUC-ROC = 0.694, 95% CI 0.536-0.853). In conclusion, IL-6, IL-10, and IFNγ might help to assess SLE serological and clinical activity. Their combination in the IL-6-IFN product and the IL-6xIFN to IL-10 ratio results in novel tools to determine and predict SA, AD, and LDAS. Prompt detection of SLE activity might allow a rapid intervention to avoid established or chronic damage.

Impact of severe infections in SLE: an observational study from the Spanish national registry.

OBJECTIVE: Infections are a common complication of SLE. Our objective was to evaluate their causes and impact on the survival of patients with SLE. METHODS: Analysis of the admissions and death causes in patients diagnosed with SLE from the Spanish Hospital Discharge Database and the infection-related deaths of the Spanish population from the National Statistical Institute, between 2016 and 2018.Only infections recorded as the main diagnosis were analysed (severe or clinically relevant infection). RESULTS: Among 18 430 admissions in patients with SLE, disease activity was the cause of admission in 19% of all patients and infection in 15%. However, infection was the main cause of death (25%) while SLE activity was responsible for only 6% of deaths (p<0.001). Severe infection exceeded SLE as a cause of death for patients dying at ages between 40-59 (23% vs 4%, p<0.001), 60-79 (26% vs 6%, p<0.001) and older than 80 years (25% vs 6%, p<0.001). Infection was the cause of death in 8% of the Spanish population, a significantly lower rate when compared with patients with SLE (p<0.001). Compared with the general population, infections were the highest relative cause of death in patients with SLE, particularly at younger ages: 40% vs 3% for those below 20 years old (p<0.01), 33% vs 4% between 20 and 39 (p<0.001), 23% vs 5% between 40 and 59 (p<0.001), 26% vs 5% between 60 and 79 (p<0.001) and 25% vs 9% for those older than 80 years (p<0.001). CONCLUSION: Our nationwide study confirms that infections are the leading cause of death in SLE in Spain, with the highest proportion occurring in young patients with lupus compared with the general population of the same age range.

[Impact of Lung Ultrasound dUring the SARS-CoV-2 Pandemic: Distinction Between Viral and Bacterial Pneumonia]. / Impacto de la ecografía pulmonar Durante la pandemia por SARS-CoV-2: distinción entre la neumonía viral y la bacteriana.

Introduction: Lung ultrasound is an accessible, low-cost technique that has demonstrated its usefulness in the prognostic stratification of COVID-19 patients. In addition, according to previous studies, it can guide us towards the potential aetiology, especially in epidemic situations such as the current one. Patients and methods: 40 patients were prospectively recruited, 30 with confirmed SARS-CoV-2 pneumonia and 10 with community-acquired pneumonia. The patients included underwent both a chest X-ray and ultrasound. Results: There were no differences in the 2 groups in terms of clinical and laboratory characteristics. The main ultrasound findings in the SARS-CoV-2 group were the presence of confluent B lines and subpleural consolidations and hepatinization in the community-acquired pneumonia group. Pleural effusion was more frequent in the community-acquired pneumonia group. There were no normal lung ultrasound exams. Analysis of the area under the curve curves showed an area under the curve for lung ultrasound of 89.2% (95% CI: 75.0-100%, p < .001) in the identification of SARS-CoV-2 pneumonia. The cut-off value for the lung score of 10 had a sensitivity of 93.3% and a specificity of 80.0% (p < .001). Discussion: The combination of the findings of the lung ultrasound, with a lung score greater than 10, added to the rest of the additional tests, can be an excellent tool to predict the aetiology of the pneumonia.

Impact of lung ultrasound during the SARS-CoV-2 pandemic: Distinction between viral and bacterial pneumonia.

INTRODUCTION: Lung Ultrasound is an accessible, low-cost technique that has demonstrated its usefulness in the prognostic stratification of COVID-19 patients. In addition, according to previous studies, it can guide us towards the potential aetiology, especially in epidemic situations such as the current one. PATIENTS AND METHODS: 40 patients were prospectively recruited, 30 with confirmed SARS-CoV-2 pneumonia and 10 with community-acquired pneumonia (CAP). The patients included underwent both a chest X-ray and ultrasound. RESULTS: There were no differences in the 2 groups in terms of clinical and laboratory characteristics. The main ultrasound findings in the SARS-CoV-2 group were the presence of confluent B lines and subpleural consolidations and hepatinization in the CAP group. Pleural effusion was more frequent in the CAP group. There were no normal lung ultrasound exams. Analysis of the area under the curve (AUC) curves showed an area under the curve for Lung Ultrasound of 89.2% (95% CI: 75%.0-100%, p < .001) in the identification of SARS-CoV-2 pneumonia. The cut-off value for the lung score of 10 had a sensitivity of 93.3% and a specificity of 80.0% (p < .001). DISCUSSION: The combination of the findings of the Lung Ultrasound, with a Lung Score greater than 10, added to the rest of the additional tests, can be an excellent tool to predict the aetiology of the pneumonia.

Severe Lymphopenia as a Predictor of COVID-19 Mortality in Immunosuppressed Patients.

BACKGROUND: Coronavirus disease 2019 (COVID-19) has a high mortality in certain group of patients. We analysed the impact of baseline immunosuppression in COVID-19 mortality and the role of severe lymphopenia in immunocompromised subjects. METHODS: We analysed all patients admitted with COVID-19 in a tertiary hospital in Madrid between March 1st and April 30th 2020. Epidemiological and clinical data, including severe lymphopenia (<500 lymphocytes/mm3) during admission, were analysed and compared based on their baseline immunosuppression condition. RESULTS: A total of 1594 patients with COVID-19 pneumonia were hospitalised during the study period. 166 (10.4%) were immunosuppressed. Immunocompromised patients were younger (64 vs. 67 years, p = 0.02) but presented higher rates of hypertension, diabetes, heart, neurological, lung, kidney and liver disease (p < 0.05). They showed more severe lymphopenia (53% vs 24.1%, p < 0.001), lower SapO2/FiO2 ratios (251 vs 276, p = 0.02) during admission and higher mortality rates (27.1% vs 13.5%, p < 0.001). After adjustment, immunosuppression remained as an independent factor related to mortality (Odds Ratio (OR): 2.24, p < 0.001). In the immunosuppressed group, age (OR = 1.06, p = 0.01), acute respiratory distress syndrome (ARDS) (OR = 12.27, p = 0.017) and severe lymphopenia (OR = 3.48, p = 0.04) were the factors related to high mortality rate. CONCLUSION: Immunosuppression is an independent mortality risk factor in COVID-19. Severe lymphopenia should be promptly identified in these patients.

Trends in Hospital Admissions and Death Causes in Patients with Systemic Lupus Erythematosus: Spanish National Registry.

BACKGROUND: the admission and death causes of SLE patients might have changed over the last years. METHODS: Analysis of the Spanish National Hospital Discharge database. All individuals admitted with SLE, according to ICD-9, were selected. The following five admission categories were considered: SLE, cardiovascular disease (CVD), neoplasm, infection, and venous-thromboembolic disease (VTED), along four periods of time (1997-2000, 2001-2005, 2006-2010, and 2011-2015). RESULTS: The admissions (99,859) from 43.432 patients with SLE were included. The absolute number of admissions increased from 15,807 in 1997-2000 to 31,977 in 2011-2015. SLE decreased as a cause of admission (from 47.1% to 20.8%, p < 0.001), while other categories increased over the time, as follows: 5% to 8.6% for CVD, 8.2% to 13% for infection, and 1.4% to 5.5% for neoplasm (p < 0.001 for all). The admission mortality rate rose from 2.22% to 3.06% (p < 0.001) and the causes of death evolved in parallel with the admission categories. A significant trend to older age was observed over time in the overall population and deceased patients (p < 0.001). CONCLUSIONS: Better control of SLE over the past two decades has led to a decrease in early admissions, and disease chronification. As a counterpart, CVD, infections, and neoplasm have become the main causes of admissions and mortality.

Risk Factors for Clostridioides Difficile Diarrhea In Solid Organ Transplantation Recipients.

BACKGROUND: There is limited knowledge about risk factors for Clostridioides difficile infection (CDI) and recurrent CDI in solid organ transplant (SOT) recipients. METHODS: A case-control study of CDI in SOT recipients compared with controls (SOT recipients who did not present CDI). RESULTS: Sixty-seven patients from 1089 SOT recipients (6.2%) suffered at least one episode of CDI. The mean age was 55 ± 12 years and 20 cases (69%) were men. The accumulated incidence was 8% in liver transplantation, 6.2% in lung transplantation, 5.4% in heart transplantation, and 4.7% in kidney transplantation. Twenty-nine cases (43.3%) were diagnosed during the first 3 months after SOT. Forty-one cases (61.2%) were hospital acquired. Thirty-one patients with CDI presented with mild-moderate infection (46.3%), 30 patients with severe infection (44.8%), and 6 patients with severe-complicated disease (9%). Independent variables found to be related with CDI were hospitalization in the previous 3 months (odds ratio: 2.99; [95% confidence interval 1.21-7.37]) and the use of quinolones in the previous month (odds ratio: 3.71 [95% confidence interval 1.16-11.8]). Eleven patients (16.4%) had at least one recurrence of CDI. Previous treatment with amoxicillin-clavulanate, severe-complicated index episode, and high serum creatinine were associated with recurrent CDI in the univariant analysis CONCLUSIONS: Liver transplant recipients presented the highest incidence of CDI among SOT recipients. Risk factors for CDI were hospitalization in the previous 3 months and the use of quinolones in the previous month.

Obesidad en la mortalidad de pacientes con insuficiencia cardiaca y fracción de eyección reducida / Obesity in the mortality of patients with heart failure and reduced ejection fraction

Introducción: La asociación entre obesidad y menor mortalidad en pacientes con insuficiencia cardiaca y fracción de eyección del ventrículo izquierdo es controversial. Objetivo: Evaluar la asociación entre obesidad y mortalidad en pacientes con insuficiencia cardiaca y fracción de eyección reducida. Métodos: Se realizó un estudio observacional de cohorte prospectivo en pacientes con insuficiencia cardiaca y fracción de eyección reducida en el período comprendido entre enero del 2010 y diciembre de 2020. La muestra quedó conformada por 173 pacientes. Se evaluó la supervivencia mediante el método de Kaplan-Meier, para estimar el efecto del pronóstico de la variable obesidad sobre la mortalidad. Se utilizó el modelo de regresión de Cox. Resultados: Se observó que los pacientes obesos al año de seguimiento tuvieron mejor supervivencia que los que presentaron normopeso (0,6 versus 0,8) a los cinco años presentaron similar supervivencia los tres subgrupos de índice masa corporal (0,6), la mayor mortalidad la presentaron los pacientes bajo peso. La curva de éstos últimos, se distancia del resto de las categorías de IMC, Log Rank p= 0,001. En el modelo de regresión de Cox la obesidad presentó un odd ration OR=´1,159 p=0,648 (intervalo de confianza de 0,615-2,181). Conclusiones: En los pacientes con insuficiencia cardiaca con fracción de eyección reducida no se observó el fenómeno de obesidad paradójica en relación a la mortalidad(AU)

Introduction: The association between obesity and lower mortality in patients with heart failure and left ventricular ejection fraction is controversial. Objective: To evaluate the association between obesity and mortality in patients with heart failure and reduced ejection fraction. Methods: An observational prospective cohort study was carried out, from January 2010 to December 2020, in patients with heart failure and reduced ejection fraction. The sample was made up of 173 patients. Survival was evaluated using Kaplan-Meier method to estimate the prognostic effect of the obesity variable on mortality. Cox regression model was used. Results: It was observed that obese patients at one year of follow-up had better survival than those with normal weight (0.6 versus 0.8). At five years, the three subgroups of body mass index (0.6) showed similar survival and the highest mortality was observed by low weight patients. The curve of the latter differs from the rest of the BMI categories, Log Rank p=0.001. In the Cox regression model, obesity had an odds ratio OR=´1.159 p=0.648 (confidence interval 0.615-2.181). Conclusions: In patients with heart failure with reduced ejection fraction, the phenomenon of paradoxical obesity was not observed in relation to mortality(AU)

Análisis de mortalidad y comorbilidad por Covid-19 en Cuba / Analysis of mortality and comorbidity due to covid-19 in Cuba

Introducción: Las comorbilidades se han relacionado con mayor riesgo de contraer COVID-19, de tener mala evolución y de mortalidad. Objetivo: Identificar factores de riesgo asociados a la mortalidad al final de la estadía hospitalaria de los pacientes con diagnóstico de COVID-19 en Cuba. Métodos: Investigación retrospectiva, de la totalidad de pacientes confirmados con COVID-19 en Cuba, con 18 años o más, diagnosticados entre el 11 de marzo al 15 de octubre de 2020. La fuente de información fue la base de datos nacional del Ministerio de Salud Pública. Se recopilaron edad, sexo y comorbilidades. Clasificados en recuperados y fallecidos. Estudio analítico de factores y comorbilidades asociadas a la mortalidad. Resultados: Se analizaron 5 490 pacientes (97,7 por ciento recuperados vs 2,3 por ciento fallecidos). Los fallecidos tenían significativamente más edad (72,8 vs 44,5 años). Las comorbilidades más frecuentes en fallecidos fueron hipertensión (47,6 por ciento vs 7,8 por ciento), diabetes (27,4 por ciento vs 2,6 por ciento), cardiopatía isquémica (14,5 por ciento vs 0,9 por ciento), enfermedad renal crónica (11,3 por ciento vs 0,3 por ciento) y EPOC (11,3 por ciento vs 0,5 por ciento).

La combinación de comorbilidades más frecuente entre los fallecidos fue: hipertensión con diabetes (17,7 por ciento vs 1,9 por ciento) e hipertensión con enfermedad renal crónica (8,1 por ciento vs 0,2 por ciento). Conclusiones: La edad avanzada, la enfermedad renal crónica, cardiopatía isquémica, insuficiencia cardiaca, hipertensión, diabetes, cáncer, enfermedad pulmonar obstructiva crónica, obesidad y el número de comorbilidades se relacionaron significativamente con la mortalidad y podrían ayudar a identificar a los pacientes con mayor riesgo(AU)

Introduction: Comorbidities have been related to highrisk of contracting COVID-19, and of having poor evolution and mortality. Objective: To identify risk factors associated with mortality at the end of the hospital stay in patients diagnosed with COVID-19 in Cuba. Methods: A retrospective cohort of all patients confirmed COVID-19 in Cuba, aged 18 years or older, diagnosed from March 11 to October 15, 2020. The source of information was the national database of the Ministry of Public health. Age, sex and comorbidities were collected, and classified as recovered and deceased. This is an analytical study of factors and comorbidities associated with mortality. Results: This study analyzed 5,490 patients (97.7 percent recovered vs 2.3 percent deceased). The deceased were significantly older (72.8 vs 44.5 years). The most frequent comorbidities in the deceased were hypertension (47.6 percent vs 7.8 percent), diabetes (27.4 percent vs 2.6 percent), ischemic heart disease (14.5 percent vs 0.9 percent), chronic kidney disease (11.3 percent vs 0.3 percent) and COPD (11.3 percent vs 0.5 percent). An independent risk of mortality was found at the age of 60 years or more (OR: 10,090, 95 percent CI: 6,247-16,299), chronic kidney disease (OR: 8,434, 95 percent CI: 3,400-20,919), cancer (OR: 7,169 , 95 percent CI: 2,920-17,601), chronic obstructive pulmonary disease (OR: 5,300, 95 percent CI: 2,376-11,822), obesity (OR: 4,230, 95 percent CI: 1,362-13,139), heart failure (OR: 4,197, CI 95 percent: 1,085-16,244), diabetes (OR: 2,360, 95 percent CI: 1,339-4,159), hypertension (OR: 2,264, 95 percent CI: 1,398-3,668) and ischemic heart disease (OR: 2,321, 95 percent CI: 1,168 -4,610). A significant association of comorbidities was found, with two, three and more than three (OR: 22.9, 95 percent CI: 13.4-39.2), (OR: 72.5, 95 percent CI: 39.8-132, 1) and (OR: 88.9, 95 percent CI: 36.2-217.8) respectively. The most frequent combination of comorbidities among the deceased subjects was hypertension with diabetes (17.7 percent vs 1.9 percent) and hypertension with chronic kidney disease (8.1 percent vs 0.2 percent). Conclusions: Advanced age, chronic kidney disease, ischemic heart disease, heart failure, hypertension, diabetes, cancer, chronic obstructive pulmonary disease, obesity and the number of comorbidities were significantly related to mortality and could help to identify patients with higher risk(AU)

Hormona antimülleriana como marcador de respuesta ovárica en pacientes tratadas por fertilización in vitro / Anti-Müllerian hormone as a marker of ovarian response in patients treated with in vitro fertilization

Introducción: La infertilidad afecta al 15 por ciento de las parejas en edad fértil, de las que aproximadamente 4-8 por ciento requerirán técnicas de reproducción asistida de alta tecnología. Con la incorporación de la mujer a la vida laboral y la consiguiente postergación de la maternidad es posible el aumento de la infertilidad. La hormona antimülleriana en la mujer se produce por las células de la granulosa. Esta regula el reclutamiento de folículos, su crecimiento y previene el agotamiento folicular, por lo que constituye una importante herramienta en los protocolos de inducción de la ovulación. Objetivo: Evaluar los niveles de la hormona antimülleriana como marcador de respuesta ovárica en pacientes tratadas por fertilización in vitro. Método: Se realizó un estudio descriptivo, observacional y de corte transversal en la consulta protocolizada de Reproducción Asistida del Hospital Clínico Quirúrgico Hermanos Ameijeiras, en el periodo comprendido de abril 2017 hasta abril 2019. La muestra quedó conformada por 137 mujeres que participaron en esta consulta. Se empleó estadística descriptiva e inferencial. Resultados: La edad promedio de las pacientes fue de 33,1 ± 7,4 años. Predominó la concentración sérica normal de la hormona antimülleriana en mujeres entre 31-35 años (26,3 por ciento), nivel normal de FSH en (39,4 por ciento), recuento de folículos antrales normal (24,1 por ciento), buena calidad ovocitaria (39,4 por ciento), y buena calidad embrionaria (36,5 por ciento). Conclusiones: El nivel sérico de la hormona antimülleriana se asoció significativamente a la edad, la hormona folículo estimulante, el recuento de los folículos antrales, y la calidad ovocitaria y embrionaria(AU)

Introduction: Infertility affects to 15 percent of the couples in childbearing age, and approximately 4-8 percent of them will need high-tech assisted reproduction techniques. With the participation of women in work life and the subsequent delay of maternity, it is possible the increase of infertility. Anti-Müllerian in women is produced by granular cells. These cells control the recruitment of follicles, their growth and prevent follicles exhaustion; therefore, it represents an important tool in the protocols of ovulation induction. Objective: Assess the levels of anti-Müllerian hormone as a marker in the ovarian response in patients treated with in vitro fertilization. Methods: It was conducted a descriptive, observational and cross-sectional study in the consultation of Assisted Reproduction in "Hermanos Ameijeiras" Surgical Clinical Hospital, in the period April, 2017 - April, 2019. The sample was formed by 137 women who attended to this consultation. It was used descriptive and inferential statistics. Results: Average age of the patients was 33,1 ± 7,4 years old. There was predominance of normal serum concentration of anti-Müllerian hormone in women among 31-35 years old (26,3 percent), FSH normal level in (39,4 percent), normal recount of antral follicles (24,1 percent), good oocyte quality (39,4 percent), and good embryonic quality (36,5 percent). Conclusions: The serum level of the anti-Müllerian hormone was significantly associated to age, the follicle-stimulating hormone, the recount of antral follicles, and the oocyte and embryonic quality(AU)
