Facial thermal and blood perfusion patterns of human emotions: Proof-of-Concept.

In this work, a preliminary study of proof-of-concept was conducted to evaluate the performance of the thermographic and blood perfusion data when emotions of positive and negative valence are applied, where the blood perfusion data are obtained from the thermographic data. The images were obtained for baseline, positive, and negative valence according to the protocol of the Geneva Affective Picture Database. Absolute and percentage differences of average values of the data between the valences and the baseline were calculated for different regions of interest (forehead, periorbital eyes, cheeks, nose and upper lips). For negative valence, a decrease in temperature and blood perfusion was observed in the regions of interest, and the effect was greater on the left side than on the right side. In positive valence, the temperature and blood perfusion increased in some cases, showing a complex pattern. The temperature and perfusion of the nose was reduced for both valences, which is indicative of the arousal dimension. The blood perfusion images were found to be greater contrast; the percentage differences in the blood perfusion images are greater than those obtained in thermographic images. Moreover, the blood perfusion images, and vasomotor answer are consistent, therefore, they can be a better biomarker than thermographic analysis in identifying emotions.

Patients With Fibromyalgia, Depression, and/or Anxiety and Sex Differences.

Fibromyalgia is a syndrome characterized by chronic widespread pain, with a multifactorial etiopathogenesis and high incidence of neuropsychiatric comorbidity. It has been inaccurately considered a pathological condition affecting only middle-aged women. The study aimed to explore the association of sociodemographic and clinical factors in patients with fibromyalgia with depression and/or anxiety. The present study is an analysis of a cross-sectional study of a secondary source. The prevalence ratio (PR) between the demographic and clinical variables of patients with fibromyalgia and concomitant depression and/or anxiety was calculated. Overall, 1,106 medical records were obtained with a confirmed diagnosis of fibromyalgia between 2010 and 2016; of these, 318 (28.75%) patients had an associated diagnosis of depression and/or anxiety. Approximately 28% women (295 of 1,052) and 42.6% men (23 of 54) suffered from depression and/or anxiety. In the adjusted explanatory model of depression and/or anxiety in patients with fibromyalgia, the relationship between sex (female PR = 0.5 [0.28-0.86]) and low socioeconomic strata (PR = 0.53 [0.33-0.70]) remained constant. In the study population, patients with fibromyalgia belonging to lower social strata were less likely to present with depression and anxiety. The male sex may pose as a risk factor for depression and/or anxiety in patients with fibromyalgia. Fibromyalgia has a huge impact on men's physical as well as mental health.

Depression and the risk of adverse outcomes at 5 years in patients with coronary heart disease.

BACKGROUND: Cardiovascular diseases are a public health concern worldwide, with high rates of morbidity and mortality. Depression is a frequent comorbidity in coronary heart disease (CHD). It can be caused by the experience of suffering from heart disease, but it can also influence the prognosis of the CHD. The prevalence of depression in patients with cardiovascular disease is twice as high as that in the general population. AIM: Assess the influence of depression in the prognosis at 5 years in patients with CHD. METHODS: 145 patients diagnosed with CHD were recruited between September 2013 and June 2015. Depression was assessed based on the PHQ-9 results at the time of hospitalization and 3 months after discharged. Sociodemographic and clinical variables were collected. A 5-year follow-up was carried out to verify death, reinfarction or any adverse outcome. RESULTS: 20% of the study population had depression at hospital admission compared with 11% at 3 months. Depression at 3 months after discharged was a differentiating factor to present complications (42.6 months, CI 95% 27.3-57.9) compared with patients without depression (55 months, CI 95%, 50.9-59.1) (Log-Rank p = 0.034). In the unadjusted model, the risk of heart complications increased with patients that have comorbidities, such as diabetes (HR 2.78, 95% CI 1.21-6.3) or hypothyroidism (HR 2.5 95% CI 1.09-5.7). Also, patients with post-hospitalization depression at 3 months were 3 times (95% CI 1.023-8.8) more likely to have complications during the follow-up period than nondepressed patients. After risk factor adjustment, the HR for depression was 2.01 (95% CI 0.57-6.9). FINDINGS: Patients with depression at 3 months following the coronary event, presented complications sooner than those without depression.

Comorbilidad neuropsiquiátrica en pacientes con fibromialgia / Neuropsychiatric comorbidity in patients with fibromyalgia

RESUMEN Introducción: La fibromialgia es una causa común de dolor crónico en el mundo, con una prevalencia en la población general del 0,2% al 6,4%. Estos pacientes tienen una mayor probabilidad de presentar trastornos neuropsiquiátricos. El objetivo fue describir el perfil sociodemográfico y clínico de pacientes con fibromialgia y comorbilidad neuropsiquiátrica. Métodos: Estudio transversal, descriptivo. Se recolectó información de las historias clínicas de pacientes con fibromialgia y comorbilidad neuropsiquiátrica, de una institución especializada en Antioquia, durante los años 2010 al 2016. Se aplicaron herramientas de estadística descriptiva. Resultados: De 1.106 registros médicos con diagnóstico confirmado de fibromialgia, 497 presentaban comorbilidad neuropsiquiátrica. La mediana de edad fue de 54 años (RIC 15), la mayoría eran mujeres, residían en zona urbana y estaban casados o convivían con su pareja. Estatus socioeconómico bajo-medio y nivel educativo básico-medio, fueron los más reportados. Los síntomas más frecuentes fueron alteraciones del sueño (70,6%), mialgias (66,4%) y fatiga crónica (55,9%). Los trastornos neuropsiquiátricos más frecuentes fueron depresión (85,7%), migraña (35%) y ansiedad (14,7%). Los fármacos más utilizados fueron los inhibidores de la recaptación de serotonina y duales, acetaminofén y gabaérgicos. Manejo con terapias complementarias e intervención psicológica se observaron en baja proporción. Conclusiones: La fibromialgia y las enfermedades neuropsiquiátricas son patologías que coexisten con frecuencia; la presentación sociodemográfica y clínica es similar a lo descrito en la literatura, sin embargo, la presencia de depresión en esta población fue mayor. Un enfoque terapéutico transdisciplinario, favorecería la calidad de vida de los pacientes y el curso de la enfermedad.

ABSTRACT Introduction: Fibromyalgia is a common cause of chronic pain in the world, with a prevalence of 0.2% to 6.4% in the general population. These patients are more likely to have neuropsychiatric disorders. The objective of this study was to describe the sociodemographic and clinical profile of patients with fibromyalgia and neuropsychiatric comorbidity. Methods: A cross-sectional, descriptive study was conducted in which Information was collected from the medical records of patients with fibromyalgia and neuropsychiatric comorbidity, from specialist institution in Antioquia, during the years 2010 to 2016. Descriptive statistics tools were applied. Results: Of the 1,106 medical records with a confirmed diagnosis of fibromyalgia, 497 had neuropsychiatric comorbidity. The median age was 54 years (IQR 15), and the majority were women, residing in an urban area, and were married or living with their partner. Low-medium socioeconomic status and basic-medium educational level were the most reported. The most frequent symptoms were sleep disturbances (70.6%), myalgia (66.4%), and chronic fatigue (55.9%). The most frequent neuropsychiatric disorders were depression (85.7%), migraine (35%), and anxiety (14.7%). The most commonly used drugs were serotonin and dual reuptake inhibitors, acetaminophen, and GABAergic drugs. A low percentage was managed with complementary therapies and psychological intervention. Conclusions: Fibromyalgia and neuropsychiatric diseases are diseases that frequently coexist. Although the sociodemographic and clinical presentation is as described in the literature, the presence of depression was greater in this population. A multidisciplinary therapeutic approach would favour the quality of life of the patients and the course of the disease.

Epidemiology of septic shock in prehospital medical services in five Colombian cities. / Epidemiología del shock séptico en un servicio de atención médica prehospitalaria en cinco ciudades colombianas.

OBJECTIVE: To explore the association between demographic and clinical factors and the presentation of septic shock in patients treated by prehospital emergency services in five Colombian cities between 2015 and 2016. METHODS: This was a cross-sectional study with retrospective data collection. Clinical and demographic data were collected from the medical records of patients diagnosed with sepsis who received prehospital care in five Colombian cities in 2015 and 2016. The diagnosis of septic shock was checked in 20% of the cases, generating two analyzed scenarios: observed and verified. Data were analyzed using the chi-square test, Student's t test and an adjusted logistic regression model. Covariates with p < 0.05 were considered significant. RESULTS: There was a higher frequency of septic shock in women (62.6%) and in individuals older than 80 years (64.5%), but these were not differentiating factors for septic shock. The most common source of infection was the urinary tract. In the observed scenario, age over 60 (prevalence ratio (PR): 3.22; 95% confidence interval (CI): 1.45 - 35.01) and history of cancer (PR: 1.20; 95%CI: 1.2 - 12.87) were the characteristics associated with septic shock, whereas in the verified scenario, chronic obstructive pulmonary disease (PR: 1.99; 95%CI: 1.26 - 7.14), history of cancer (PR: 1.15; 95%CI: 1.11 - 6.62) and presence of hypovolemia (PR: 1.41; 95%CI: 1.02 - 5.50) were observed. CONCLUSION: The most important risk factors for septic shock in prehospital care patients in five Colombian cities were oncological and pulmonary diseases and hypovolemia.

RESUMEN Objetivo: Explorar la asociación entre factores demográficos y clínicos con la presentación de shock séptico en pacientes atendidos en un servicio prehospitalario de emergencias en cinco ciudades colombianas entre los años 2015-2016. Métodos: Estudio de corte transversal con recolección retrospectiva de datos. Se recolectó información clínica y demográfica de las historias clínicas de pacientes con diagnóstico de sepsis que recibieron atención prehospitalaria en cinco ciudades colombianas en los años 2015 y 2016. Se realizó una verificación del diagnóstico de shock séptico en el 20% de los casos, dando origen a dos escenarios analizados: observado y verificado. Se analizó la asociación con pruebas de Chi cuadrado, t de Student y finalmente con un modelo de regresión logística ajustado. Se consideró covariables significativas aquellas con p < 0,05. Resultados: Se presentó una mayor frecuencia del evento en mujeres (62,6%) y en mayores de 80 años (64,5%), sin ser factores diferenciadores para shock séptico. El foco infeccioso más común fue urinario. En el escenario observado, los mayores de 60 años (RP: 3,22; IC95%: 1,45 - 35,01) y el antecedente de cáncer fueron las características asociadas con el shock séptico (RP: 1,20; IC95%: 1,2 - 12,87), mientras que en el grupo verificado fueron la enfermedad pulmonar obstructiva crónica (RP: 1,99; IC95%: 1,26 - 7,14), el antecedente de cáncer (RP: 1,15; IC95%: 1,11 - 6,62) y presencia de hipovolemia (RP: 1,41; IC95%: 1,02 - 5,50). Conclusión: Los factores de riesgo más importantes para shock séptico en pacientes de atención prehospitalaria en cinco ciudades colombianas fueron las enfermedades oncológicas, las pulmonares e hipovolemia.
