Patrones y factores dietéticos y su asociación con la ansiedad en población adulta: propuesta de recomendaciones basada en una revisión de alcance de revisiones sistemáticas y metaanálisis / Dietary patterns and factors and their association with the anxiety in adult population: proposed recommendations based on a scoping review of systematic reviews and meta-analyses

Un alto porcentaje de la población sufre ansiedad, trastorno que puede verse influenciado por los hábitos dietéticos. El objetivo de esta revisión fue recopilar la evidencia existente sobre los patrones y factores dietéticos, y su asociación con la ansiedad para proponer unas recomendaciones clínicamente aplicables. Se realizó una revisión de alcance (Scoping Review) de revisiones sistemáticas y metaanálisis en la base de datos MEDLINE (PubMed) hasta enero de 2021, informando de los principales hallazgos según PRISMA (2020). Para construir la estrategia de búsqueda, se emplearon el lenguaje MeSH, palabras clave (“dieta”, “nutrientes”, “estilo de vida saludable”, “ansiedad”) y filtros, combinándose mediante operadores booleanos. Se seleccionaron 12 artículos, siete revisiones sistemáticas con metaanálisis y cinco revisiones sistemáticas. Se obtuvieron diversos resultados en los que se evaluaba la relación entre la ansiedad y diferentes aspectos de la dieta. Las principales asociaciones encontradas se observaron entre un mayor consumo de verduras crudas y frutas, la sustitución de cereales refinados por integrales, la ingesta de AGP omega-3 y omega-6 y el incremento del consumo de minerales y vitaminas, triptófano y antioxidantes. De acuerdo con las revisiones sistemáticas y metaanálisis incluidos como resultados, se propusieron diez recomendaciones sobre el consumo de alimentos y la ingesta de nutrientes que deberían priorizarse en estos pacientes. Según la literatura revisada, se concluye que existen patrones y factores dietéticos que podrían ejercer una mayor influencia protectora sobre la ansiedad. Esta propuesta de recomendaciones dietéticas basadas en la evidenciapermitirá a los profesionales sanitarios disponer de unas pautas actualizadas que sirvan como una primera guía. (AU)

A high percentage of the population suffers from anxiety, a disorder that can be influenced by dietary habits. The aim of this review was to compile the existing evidence on dietary patterns and factors, and their association with anxiety to propose clinically applicable recommendations. A scoping review of systematic reviews and meta-analyses was conducted in the MEDLINE database (PubMed) until January 2021, reporting the main findings based on PRISMA (2020). To construct the search strategy, MeSH language, keywords (“diet”, “nutrients”, “healthy lifestyle”, “anxiety”) and filters were used, combined using Boolean operators. Twelve articles, seven systematic reviews with meta-analysis and five systematic reviews were selected. Several results were obtained evaluating the relationship between anxiety and different aspects of diet. The main associations found were between increased consumption of raw vegetables and fruits, substitution of refined cereals by whole grains, intake of omega-3 and omega-6 fats, and increased intake of minerals and vitamins, tryptophan and antioxidants. Based on the systematic reviews and meta-analyses included as findings, ten recommendations on food consumption that should be considered as a priority for these patients were proposed. Based on the literature reviewed, it is concluded that there are dietary patterns and factors that could have a stronger positive influence on anxiety. This proposal of evidence-based dietary recommendations may allow healthcare professionals to have updated recommendations to provide a first orientation. (AU)

Outcomes of patients with COVID-19 in the intensive care unit in Mexico: A multicenter observational study.

BACKGROUND: As of June 15, 2020, a cumulative total of 7,823,289 confirmed cases of COVID-19 have been reported across 216 countries and territories worldwide. However, there is little information on the clinical characteristics and outcomes of critically ill patients with severe COVID-19 who were admitted to intensive care units (ICUs) in Latin America. The present study evaluated the clinical characteristics and outcomes of critically ill patients with severe COVID-19 who were admitted to ICUs in Mexico. METHODS: This was a multicenter observational study that included 164 critically ill patients with laboratory-confirmed COVID-19 who were admitted to 10 ICUs in Mexico, from April 1 to April 30, 2020. Demographic data, comorbid conditions, clinical presentation, treatment, and outcomes were collected and analyzed. The date of final follow-up was June 4, 2020. RESULTS: A total of 164 patients with severe COVID-19 were included in this study. The mean age of patients was 57.3 years (SD 13.7), 114 (69.5%) were men, and 6.0% were healthcare workers. Comorbid conditions were common in patients with critical COVID-19: 38.4% of patients had hypertension and 32.3% had diabetes. Compared to survivors, nonsurvivors were older and more likely to have diabetes, hypertension or other conditions. Patients presented to the hospital a median of 7 days (IQR 4.5-9) after symptom onset. The most common presenting symptoms were shortness of breath, fever, dry cough, and myalgias. One hundred percent of patients received invasive mechanical ventilation for a median time of 11 days (IQR 6-14). A total of 139 of 164 patients (89.4%) received vasopressors, and 24 patients (14.6%) received renal replacement therapy during hospitalization. Eighty-five (51.8%) patients died at or before 30 days, with a median survival of 25 days. Age (OR, 1.05; 95% CI, 1.02-1.08; p<0.001) and C-reactive protein levels upon ICU admission (1.008; 95% CI, 1.003-1.012; p<0.001) were associated with a higher risk of in-hospital death. ICU length of stay was associated with reduced in-hospital mortality risk (OR, 0.89; 95% CI, 0.84-0.94; p<0.001). CONCLUSIONS: This observational study of critically ill patients with laboratory-confirmed COVID-19 who were admitted to the ICU in Mexico demonstrated that age and C-reactive protein level upon ICU admission were associated with in-hospital mortality, and the overall hospital mortality rate was high.

Terapia de pareja: reflexiones sistémicas de un grupo en formación / Couple therapy: systemic reflections in a formative group

Se presentan a continuación algunas ideas y reflexiones planteadas como resultado del trabajo en equipo llevado a cabo durante el curso de terapia de pareja en el proceso de formación como especialistas en terapia familiar de la Universidad Católica Luis Amigó. Inicialmente se plantean algunos datos históricos e ideas acerca de la forma en que los cambios socioculturales han modificado las relaciones, aportando a la consolidación de nuevas formas de ser pareja. Se analizan características de dicha diada y el lugar del amor en su conformación, a la luz de nuevas comprensiones de las dinámicas del mundo contemporáneo y las problemáticas actuales. Concluyendo este recorrido se reconoce la vigencia e importancia de la terapia sistémica como alternativa para el abordaje de las problemáticas de pareja y se describen asuntos propios de dicha intervención, resaltando en ellos el lugar del terapeuta. Se concluye con la idea de la pareja como producto de un proceso de transformación transversalizado por la sociedad y la cultura, con diversos matices y formas de ser, que siendo cambiantes mantienen como constante la idea de pareja como un sistema interaccional complejo, en el que amor, deseo y pasión movilizan sentimientos y emociones vitales que revelan simultáneamente la fragilidad y fuerza del ser humano capaz de transformarlo. Vista de este modo la pareja es un escenario de intervención del terapeuta sistémico y la terapia el encuentro que posibilita el cambio.

Below are some ideas and reflections raised as a result of the team work carried out during the course of couple therapy in the process of training as specialists in family therapy at the Universidad Católica Luis Amigo. Initially, some historical data and ideas about the way in which socio-cultural changes have changed relationships are presented, contributing to the consolidation of new ways of being a couple. We analyze the characteristics of this dyad and the place of love in its conformation, in the light of new understandings of the dynamics of the contemporary world and the current problems. Concluding this tour, the validity and importance of systemic therapy is recognized as an alternative for the treatment of the problems of couples and describes specific issues of this intervention, highlighting in them the place of the therapist. It concludes with the idea of the couple as the product of a process of transformation that is mainstreamed by society and culture, with different nuances and ways of being, which, while being constant, maintain the idea of a constant as a complex interactional system in which Love, desire and passion mobilize feelings and vital emotions that simultaneously reveal the fragility and strength of the human being capable of transforming it. In this way the couple is a scenario of systemic therapist intervention and therapy the encounter that makes change possible.

Outcomes of critically ill cancer patients with Acinetobacter baumannii infection.

AIM: To describe the intensive care unit (ICU) outcomes of critically ill cancer patients with Acinetobacter baumannii (AB) infection. METHODS: This was an observational study that included 23 consecutive cancer patients who acquired AB infections during their stay at ICU of the National Cancer Institute of Mexico (INCan), located in Mexico City. Data collection took place between January 2011, and December 2012. Patients who had AB infections before ICU admission, and infections that occurred during the first 2 d of ICU stay were excluded. Data were obtained by reviewing the electronic health record of each patient. This investigation was approved by the Scientific and Ethics Committees at INCan. Because of its observational nature, informed consent of the patients was not required. RESULTS: Throughout the study period, a total of 494 critically ill patients with cancer were admitted to the ICU of the INCan, 23 (4.6%) of whom developed AB infections. Sixteen (60.9%) of these patients had hematologic malignancies. Most frequent reasons for ICU admission were severe sepsis or septic shock (56.2%) and postoperative care (21.7%). The respiratory tract was the most frequent site of AB infection (91.3%). The most common organ dysfunction observed in our group of patients were the respiratory (100%), cardiovascular (100%), hepatic (73.9%) and renal dysfunction (65.2%). The ICU mortality of patients with 3 or less organ system dysfunctions was 11.7% (2/17) compared with 66.6% (4/6) for the group of patients with 4 or more organ system dysfunctions (P = 0.021). Multivariate analysis identified blood lactate levels (BLL) as the only variable independently associated with in-ICU death (OR = 2.59, 95%CI: 1.04-6.43, P = 0.040). ICU and hospital mortality rates were 26.1% and 43.5%, respectively. CONCLUSION: The mortality rate in critically ill patients with both HM, and AB infections who are admitted to the ICU is high. The variable most associated with increased mortality was a BLL ≥ 2.6 mmol/L in the first day of stay in the ICU.

[Pulmonary hypertension associated with connective tissue diseases]. / Hipertensión arterial pulmonar por ecocardiografía en pacientes con enfermedades de tejido conectivo.

BACKGROUND: Pulmonary arterial hypertension is an important cause of complications among patients with connective tissue diseases. AIM: To describe the clinical and echocardiographic characteristics of patients with pulmonary hypertension associated with connective tissue diseases. MATERIAL AND METHODS: Retrospective, observational and descriptive study. We analyzed 35 patients with pulmonary hypertension associated with connective tissue diseases. All patients were evaluated and diagnosed by at least one medical specialist in rheumatology. Pulmonary arterial hypertension was defined as a pulmonary artery systolic pressure ≥ 40 mmHg by echocardiography. The group was divided as not severe when pressures ranged from 40 to 64 mmHg and severe, when pressures were ≥ 65 mmHg. RESULTS: The most common connective tissue disease associated with pulmonary arterial hypertension was diffuse scleroderma in 46% of cases. Eighty nine percent of patients were female. Time of evolution of the pulmonary hypertension was 18.8 ± 21.8 months. The distance walked in the six minute walk test was < 400 m both in patients with and without severe pulmonary hypertension. Fifty one percent of patients had pulmonary restriction. No differences in gas exchange parameters were observed between groups. Comparing echo cardio-graphic findings in patients with and without severe hypertension, the former had a higher frequency of right ventricular dilatation (85.7 and 52.3% respectively, p = 0.04), right ventricular hypertrophy (42.8 and 0% respectively, p = 0.02) and right ventricular hypokinesia (71.4 and 9.5% respectively p = < 0.01). CONCLUSIONS: Patients with severe pulmonary arterial hypertension associated to connective tissue diseases have more commonly dilated, hypertrophic and hypokinetic right ventricles.

Outcome of critically ill patients with hematological malignancies.

The prognosis for patients with hematological malignancies (HMs) admitted to the intensive care unit (ICU) is poor. The objective of this study was to evaluate the clinical characteristics and hospital outcomes of critically ill patients with HMs admitted to an oncological ICU. This is a prospective, observational cohort study. A total of 102 patients with HMs admitted to ICU from January 2008 to April 2011 were included. Univariate and multivariate logistic regressions were used to identify factors associated with hospital mortality. During the study period, 3,776 patients with HM were admitted to the Department of Hematology of the Instituto Nacional de Cancerología located in Mexico City, Mexico. After being evaluated by the intensivist, 102 (2.68 %) patients were admitted to the ICU. The ICU mortality rates for patients who had two or less organ system failures and for those with three or more organ system dysfunctions were 20 % (5/25) and 70.1 % (54/77), respectively (P < 0.0001). A multivariate analysis identified independent prognostic factors of in-hospital death as neutropenia at the time of ICU admission (odds ratio (OR), 4.24; 95 % confidence interval (CI), 1.36-13.19, P = 0.012), the need for vasopressors (OR, 4.49; 95 % CI, 1.07-18.79, P = 0.040), need for invasive mechanical ventilation (OR, 4.49; 95 % CI, 1.07-18.79, P = 0.040), and serum creatinine >106 µmol/L (OR, 3.21; 95 % CI, 1.05-9.85, P = 0.041). The ICU and hospital mortality rates were 46.1 and 57.8 %, respectively. The independent prognostic factors of in-hospital death were the need for invasive mechanical ventilation, the need for vasopressors, serum creatinine >106 µmol/L, and neutropenia at the time of ICU admission.

Mortality of patients with cancer admitted to intensive care unit.

Outcomes of critically ill cancer patients admitted to the intensive care unit (ICU) had improved; it could be associated with medical advances in critical care, introduction of new anticancer treatments, and better supportive care. Recent reports have described ICU mortality for critically ill cancer patients ranged from 15.9% to 32%. During the period 2007 to 2011, a total of 1418 critically ill cancer patients were admitted to our ICU with a mortality rate lower (17.5%) than that reported by other centers. The ICUs around the world should consider the improvement in the prognosis of critically ill cancer patients who require critical care and they should not be denied ICU admission only on the basis of a patient having cancer.

Outcomes of critically ill gynecological cancer patients admitted to intensive care unit.

PURPOSE: To assess the characteristics of critically ill patients with gynecological cancer, and to evaluate their prognosis. METHODS: Fifty-two critically ill patients with gynecological cancer admitted to intensive care unit (ICU) were included. Univariate and multivariate logistic regressions were used to identify factors associated with hospital mortality. RESULTS: Thirty-five patients (67.3%) had carcinoma of the cervix uteri and 11 (21.2%) had ovarian cancer. The mortality rate in the ICU was 17.3% (9 of 52) and hospital mortality rate were 23%(12 of 52). In the multivariate analysis, independent prognostic factors for hospital mortality were vasopressor use (odds ratio [OR] = 8.60, 95% confidence interval [CI] 2.05-36; P = .03) and the Acute Physiology and Chronic Health Evaluation (APACHE) II score (OR = 1.43, 95% CI 1.01-2.09; P = .048). CONCLUSIONS: The independent prognostic factors for hospital mortality were the need for vasopressors and the APACHE II score.

Acute respiratory distress syndrome caused by influenza B virus infection in a patient with diffuse large B-cell lymphoma.

Influenza B virus infections are less common than infections caused by influenza A virus in critically ill patients, but similar mortality rates have been observed for both influenza types. Pneumonia caused by influenza B virus is uncommon and has been reported in pediatric patients and previously healthy adults. Critically ill patients with pneumonia caused by influenza virus may develop acute respiratory distress syndrome. We describe the clinical course of a critically ill patient with diffuse large B-cell lymphoma nongerminal center B-cell phenotype who developed acute respiratory distress syndrome caused by influenza B virus infection. This paper emphasizes the need to suspect influenza B virus infection in critically ill immunocompromised patients with progressive deterioration of cardiopulmonary function despite treatment with antibiotics. Early initiation of neuraminidase inhibitor and the implementation of guidelines for management of severe sepsis and septic shock should be considered.

Critical care for patients with cancer.

Malignancies are becoming increasingly common, especially as the population ages, and patients with cancer are likely to represent an increasing proportion of ICU populations. Advances in oncological and supportive care have led to improved prognosis and extension of survival time in patients with cancer. The National Institute Cancer located in Mexico City has an oncological ICU with 6 beds. During the biennium 2008-2009, 573 patients with cancer were admitted to the ICU. The mean age was 51 ± 16.36 years and 58.6% were women. The length of stay in the ICU was 2 days (interquartile range; 1-5). The 71.6% were surgical patients. The mortality rate was 15.9%. Patients with hemato-oncological cancer had higher ICU mortality rate than subgroup of critically ill patients with solid tumors (39.5% versus 11.9%). The course of organ dysfunction over first days of life-sustaining treatment before admission to ICU could be useful for physicians who treat critically ill cancer patients to detect patients who should be admitted to ICU to try to avoid the progression to multiple organ dysfunction. On the other hand, admission to the ICU should be offered to patients with newly diagnosed cancer and acute life-threatening cancer related events. The critical care of patients with cancer contribute and support to continue the fight against cancer.

Hypoalbuminemia in critically ill patients with cancer: incidence and mortality.

PURPOSE: The aim of this study was to investigate the incidence of hypoalbuminemia in critically ill patients with cancer and to describe the relationship of serum albumin levels to mortality. DESIGN: An observational cohort study. There were no interventions. RESULTS: During the study period, 200 patients were eligible for inclusion. A total of 164 (82%) patients had a serum albumin concentration below 35 g/L, of which 91 (55.5%) patients had levels of albumin ≤20 g/L. The mean serum albumin was 18.17 g/L. The crude mortality rate was 22.5%. The highest mortality rate (73%) was seen in the group of patients whose serum albumin levels were <20 g/L. CONCLUSION: The incidence of hypoalbuminemia in critically ill patients with cancer admitted to ICU was high.
