The Influence of Physical Activity and Positive Affect on the Relationship between Pain Severity and Cognitive Performance in Women with Fibromyalgia.

Fibromyalgia, characterized by chronic pain and cognitive impairments, significantly impacts patients' quality of life. Physical exercise has been shown to improve cognitive functions and reduce pain severity. Additionally, positive affect enhances cognitive flexibility and facilitates better adaptation to chronic pain, suggesting that combining physical activity and positive affect could mitigate cognitive deficits in fibromyalgia patients. Objectives: The objective of this work is to explore the relationship between pain severity and cognitive performance through time spent doing moderate physical activity while taking into account the role of positive affect in fibromyalgia. Methods: This prospective study was structured into two phases of evaluation. First, pain severity, positive affect, and time spent performing moderate physical activity were evaluated, and one week later cognitive performance (assessed through the Stroop test) was also evaluated. The final sample consisted of 231 women with fibromyalgia. Moderated mediation analyses were performed using PROCESS. Results: The moderated mediation model showed that the effect of moderate physical activity on the relationship between pain severity and cognitive performance was significant for low levels of positive affect but not for moderate or high levels. That is, the indirect effect of pain intensity on cognitive performance through time spent doing moderate physical activity only has an effect when patients with fibromyalgia present low levels of positive affect. However, there was no significant indirect effect in the simple mediation model. Conclusions: The findings of this study underscore the importance of considering the level of positive affect when examining the impact of moderate physical activity on cognitive performance in women with fibromyalgia.

Critical Issues for Patients and Caregivers in Neuro-Oncology during the COVID-19 Pandemic: What We Have Learnt from an Observational Study.

OBJECTIVE: The COVID-19 pandemic affected neuro-oncological patients and their caregivers regarding tumor care and emotional functioning, including Quality of Life (QoL). This study aimed to understand how COVID-19 affected their psychological state and the relations between patients and health personnel in neuro-oncology. METHODS: A cross-sectional study was conducted on neuro-oncological patients and their caregivers. RESULTS: A total of 162 patients and 66 caregivers completed the questionnaire. Altogether, 37.5% of patients perceived a greater risk of contracting COVID-19 compared to the general population. On a 0-10 scale, the patients' tumor-related anxiety score was 5.8, and their COVID-19-related score was 4.6. The caregivers reported 7.7 and 5.5, respectively. QoL was described as at least good in 75% of both patients and caregivers; the caregivers' care burden increased in 22.7% of cases during the pandemic, with no correlation with QoL. Future perception often changed, both in patients and caregivers. In 18% of cases, the cancer treatment schedule was changed, either by patient decision or by medical decision. However, 93.5% of patients were satisfied with their overall care. CONCLUSIONS: A considerable proportion of patients and caregivers still perceived the tumor disease as more burdensome than the pandemic, and their future as more uncertain. Such data suggest the need to build a productive alliance between patients and health professionals.

Characteristics of Coronary Atherosclerosis Related to Plaque Burden Regression During Treatment With Alirocumab: The ARCHITECT Study.

BACKGROUND: Intensive lipid-lowering therapy may induce coronary atherosclerosis regression. Nevertheless, the factors underlying the effect of lipid-lowering therapy on disease regression remain poorly characterized. Our aim was to determine which characteristics of atherosclerotic plaque are associated with a greater reduction in coronary plaque burden (PB) after treatment with alirocumab in patients with familial hypercholesterolemia. METHODS: The ARCHITECT study (Effect of Alirocumab on Atherosclerotic Plaque Volume, Architecture and Composition) is a phase IV, open-label, multicenter, single-arm clinical trial to assess the effect of the treatment with alirocumab for 78 weeks on the coronary atherosclerotic PB and its characteristics in subjects with familial hypercholesterolemia without clinical atherosclerotic cardiovascular disease. Participants underwent a coronary computed tomographic angiography at baseline and a final one at 78 weeks. Every patient received alirocumab 150 mg subcutaneously every 14 days in addition to high-intensity statin therapy. RESULTS: One hundred and four patients were enrolled. Median age was 53.3 (46.2-59.4) years and 54 were women (51.9%). The global coronary PB changed from 34.6% (32.5%-36.8%) at entry to 30.4% (27.4%-33.4%) at follow-up, which is -4.6% (-7.7% to -1.9%; P<0.001) reduction. A decrease in the percentage of unstable core (fibro-fatty+necrotic plaque; from 14.1 [7.9-22.3] to 8.0 [6.4-10.6]; -6.6%; P<0.001) was found. A greater PB (ß, 0.36 [0.13-0.59]; P=0.002) and a higher proportion of unstable core (ß, 0.15 [0.08-0.22]; P<0.001) were significantly related to PB regression. CONCLUSIONS: Treatment with alirocumab in addition to high-intensity statin therapy might produce a greater PB regression in patients with familial hypercholesterolemia with higher baseline PB and in those with larger unstable core. Further studies are needed to corroborate the hypothesis raised by these results. REGISTRATION: URL: https://www.clinicaltrials.gov; Unique identifier: NCT05465278.

Preference for Hedonic Goals in Fibromyalgia; Is It Always an Avoidance Mechanism? Looking the Relationship with Pain Acceptance from a Positive Psychology Perspective.

The aim of this study was to analyze the effect of openness to experience on pain acceptance through positive affect (PA) considering the moderating role of preference for mood management goals in women with fibromyalgia (FM). A cross-sectional study (n = 231) was carried out. A simple mediation model and a moderate mediation model were conducted by SPSS macro-PROCESS. Results showed that PA mediated positively the effect of openness to experience on acceptance (B = 0.46, SE = 0.80, t = 5,59; 95% CI = [0.3016, 0.6298], p < .001) and that the contribution of openness to experience to PA varied at different values of mood management goals (medium: - .04; ß = .40, p < .001; high: .95; ß = .61, p<.001). Findings may serve as a foundation for tailored interventions to promote activity through acceptance focusing on PA and mood management goals among women with medium to high level of hedonic goals.

How to Generate Self-Efficacy despite Pain: The Role of Catastrophizing and Avoidance in Women with Fibromyalgia.

BACKGROUND AND OBJECTIVE: Fibromyalgia-related pain is influenced by numerous factors, including severity, as well as cognitive profiles based on pain catastrophizing or activity patterns. In this context, self-efficacy is identified as a potential predictor for explaining certain health outcomes. This study aimed to contribute to exploring the role of pain avoidance (as activity pattern) between pain severity and self-efficacy along pain catastrophizing. METHODS: Through a cross-sectional study, a total of 264 women with fibromyalgia completed self-report measures of pain severity, pain avoidance, pain catastrophizing, and self-efficacy. The severity of the symptoms, the time elapsed since diagnosis, and the time elapsed since the onsets of symptoms were included as covariates to control. Regression-based moderated-mediation analysis was used to test the conditional effect of pain severity on self-efficacy via pain avoidance at varying levels of pain catastrophizing. RESULTS: Pain avoidance mediated the effect of pain severity on self-efficacy. The indirect effects showed a moderated effect when patients scored high on the pain catastrophizing scale. The model evaluated, where catastrophic pain moderates the indirect effect of pain intensity on self-efficacy through pain avoidance, explained 49% of the variance. CONCLUSIONS: Catastrophic beliefs associated with pain as being uncontrollable increase the relationship between pain severity and pain avoidance. In turn, pain avoidance is associated with a low perception of capacity.

Effectiveness and safety in the management of chronic inflammatory diseases with etanercept and infliximab biosimilars in Colombian patients

Objective: To determine the effectiveness and safety of infliximab and etanercept biosimilar drugs in patients diagnosed with rheumatoid arthritis, ankylosing spondylitis, ulcerative colitis, and psoriasis in a specialized institution in Colombia, between 2015 and 2019. Methods: A retrospective study in patients treated with infliximab and etanercept biosimilar drugs treated in an institution specializing in the management of rheumatological diseases, to verify the clinimetric indicators of effectiveness and reports of adverse drug reactions. Clinical, sociodemographic, and pharmacological variables were identified over 5 years of follow-up. Results: 207 patients were identified with a mean age of 48.7 ± 15.1 years, 61.4% were women. Of the patients, 58.0% (n = 120) used infliximab and 42.0% (n = 87) etanercept. It was found that 46 (22.2%) patients had adverse drug reactions. At the end of the observation period, 61.6% (n = 72) of the patients with RA had achieved control of the disease (mild activity or remission), and 57.9% (n = 117) had problems with access to and persistence with therapy. Conclusion: In a group of patients treated in Colombia, the biosimilars of infliximab and etanercept showed proportions of effectiveness and safety comparable to the reference drugs, but lack of adherence to treatment was quite common.

Objetivo: Determinar la efectividad y la seguridad de medicamentos biosimilares de infliximab y etanercept en pacientes con diagnóstico de artritis reumatoide, espondilitis anquilosante, colitis ulcerativa y psoriasis en una institución especializada de Colombia, entre los arios 2015 y 2019. Métodos: Estudio retrospectivo, en pacientes tratados con infliximab y etanercept biosimilares, atendidos en una institución especializada en el manejo de enfermedades reumatológicas, para verificar los indicadores clinimétricos de efectividad y reportes de reacciones adversas medicamentosas. Se identificaron variables clínicas, sociodemográficas y farmacológicas durante cinco años de seguimiento. Resultados: Se identificaron 207 pacientes, con una edad media de 48,7 ± 15,1 años, el 61,4% de los cuales eran mujeres. El 58% (n = 120) de los pacientes utilizó infliximab y el 42% (n = 87) etanercept. Se encontró que 46 (22,2%) pacientes presentaron reacciones adversas al medicamento. Al final del periodo de observación, un 61,6% (n = 72) de los pacientes con AR había alcanzado el control de la enfermedad (actividad leve o remisión) y, en general, el 57,9% (n = 117) tuvo problemas de acceso y persistencia a la terapia. Conclusión: En un grupo de pacientes tratados en Colombia, los biosimilares de infliximab y etanercept mostraron proporciones de efectividad y seguridad comparables a los medicamentos de referencia, pero fue bastante común la falta de adherencia al tratamiento.

Impact of smoking on protein levels of beta-defensins in periodontal disease

Abstract Antimicrobial peptides (AMPs) are important components of the host response against invading pathogens. In addition to their direct antimicrobial activity, they can also participate in the immune system modulation. However, the role of AMPs in the etiopathogenesis of periodontal disease and the risk factors that may influence their expression in the oral cavity are not fully understood. The aim of this study was to determine the impact of smoking on beta-defensin (hBD) 1 and 2 levels analyzing samples from periodontitis patients. Fifty patients with periodontitis, 25 smokers and 25 non-smokers, and 20 periodontally healthy patients were recruited. After periodontal clinical evaluation, gingival crevicular fluid (GCF) samples were collected from healthy sites of patients without periodontal disease and from healthy and diseased sites of patients with periodontitis. Peptides quantification was performed by sandwich ELISA technique. Smokers showed reduced GCF hBD 1 levels and increased hBD 2 levels compared to non-smokers in diseased sites (p <0.05). Higher levels of hBD 1 were observed in healthy sites of patients without periodontal disease than in healthy sites of patients with periodontitis (p<0.0001). Diseased sites of non-smokers presented higher levels of hBD 2 than healthy sites (p <0.05). These results reveal that protein levels of hBDs 1 and 2 can be impaired by cigarette smoking in the presence of periodontal disease.

Resumo Peptídeos antimicrobianos (PAMs) são componentes importantes da resposta do hospedeiro contra patógenos invasores. Além de sua atividade antimicrobiana direta, eles também podem participar da modulação do sistema imunológico. No entanto, o papel dos PAMs na etiopatogenia da doença periodontal e os fatores de risco que podem influenciar a sua expressão na cavidade oral não são totalmente compreendidos. O objetivo deste estudo foi determinar o impacto do tabagismo nos níveis de beta-defensina (hBD) 1 e 2 analisando amostras de pacientes com periodontite. Cinquenta pacientes com periodontite, 25 fumantes e 25 não fumantes e 20 pacientes periodontalmente saudáveis foram recrutados. Após avaliação clínica periodontal, amostras de fluido crevicular gengival (FCG) foram coletadas de sítios saudáveis de pacientes sem doença periodontal e de sítios saudáveis e doentes de pacientes com periodontite. A quantificação dos peptídeos foi realizada pela técnica de ELISA sanduíche. Fumantes apresentaram níveis reduzidos de hBD 1 no FCG e níveis aumentados de hBD 2 em comparação com não fumantes em locais doentes (p <0,05). Níveis mais elevados de hBD 1 foram observados em sítios saudáveis de pacientes sem doença periodontal do que em sítios saudáveis de pacientes com periodontite (p<0,0001). Os sítios doentes de não fumantes apresentaram níveis mais elevados de hBD 2 do que os sítios saudáveis (p<0,05). Esses resultados revelam que os níveis das hBDs 1 e 2 podem ser prejudicados pelo tabagismo na presença de doença periodontal.

Caracterización sociodemográfica y clínica del trauma maxilofacial en un hospital de referencia de Bogotá / Clinical and sociodemographic characteristics of maxillofacial injuries in a tertiary hospital in Bogotá

Introducción: el trauma maxilofacial es un motivo de consulta frecuente, y puede llevar a daño funcional, estético y emocional. Existen estudios previos sobre su epidemiología, sin embargo, sabemos que esta cambia a través del tiempo porque está determinada por diversos factores. El objetivo de este estudio es describir las características del trauma maxilofacial en un hospital de referencia de Bogotá. Diseño: estudio observacional descriptivo. Metodología: Se revisaron historias clínicas de pacientes mayores de 18 años que ingresaron por urgencias a la Unidad de Cirugía Maxilofacial del Hospital San José entre el 2013 y 2017. Se calculó frecuencias absolutas y relativas para las variables cualitativas. Resultados: se obtuvieron 391 pacientes. La mayoría fueron hombres (76,3 %) entre los 30-49 años. Las causas más comunes son la violencia (36,8 %) y los accidentes de tránsito (25 %). Las fracturas más frecuentes fueron las de huesos propios nasales (52 %). De las fracturas mandibulares, las más prevalentes fueron las fracturas condilares y subcondilares, ángulo y cuerpo con 21,4 % cada una. El tratamiento más usado fue el manejo médico (52,9 %). Discusión: el trauma maxilofacial es una patología frecuente en hombres adultos jóvenes. Sin embargo, el tipo de fractura y etiología podría estar influenciado por factores como el sexo y la edad. La causa más común es la violencia y los accidentes de tránsito, las cuales son potencialmente prevenibles. Esto debe servir como referencia para incitar a la realización de medidas preventivas para estas situaciones.

Background: Nowdays, the maxilofacial injuries are a common cause for consultation in the emergency department. These kinds of fractures may cause functional, and emotional damage. There are many publication about the epidemiology of maxilofacial trauma. Nevertheless, this data can change through the time. The aim of this study was to describe the maxilofacial injuries in a tertiary hospital in Bogotá. Desing: observational study. Methods: We retrospectibly assessed 391 medical records from the department of maxilofacial surgery in our Hospital during the period between 2013 to 2017. We include patients over 18 years admitted in the emergency department, we exclude patients seeing in the outpatients clinic. All the cases were assessed according age, sex, etiology and type of the fractures, in addition, we analyzed the treatment modalities. Results: We recolected 391 medical records. The majority of the facial fractures were man (76.3 %) between 30 and 49 years old. The most common cause of maxilofacial fracture was violence (36.8 %). The most common fracture site was nasal bones (52 %). Within the mandibular fractures the most common was the condylar, subcondylar fracture and body (21 % each). 53 % of cases were treated with conservative methods. Conclusion: The maxilofacial injuries are a common in our service especially in young men. Moreover depending on the sex and age we could observed diferents etiologies and typess of fracture. Mostly of the cases were for violence reasons or traffic accidents, which are preventable causes. This information is importante for public health awarness and it can be use as a referral for prevental measures for this situations.

Nutrición de yodo en mujeres embarazadas del área de Oviedo. ¿Es necesaria la suplementación con yodo? / Iodine nutrition in pregnant women from Oviedo area. Is iodine supplementation necessary?

INTRODUCCIÓN Y OBJETIVO: En Asturias, donde la deficiencia de yodo fue erradicada en los escolares en el año 2000, persistía una deficiencia de yodo en las mujeres embarazadas, por lo que se les recomendaba la utilización de suplementos yodados. El objetivo de este estudio es conocer la nutrición de yodo de las mujeres embarazadas de nuestra área y la necesidad o no de suplementos yodados. MATERIAL Y MÉTODOS: Durante mayo y junio de 2013 hemos estudiado la nutrición de yodo y la función tiroidea en el primer trimestre del embarazo de 173 mujeres del área sanitaria de Oviedo. RESULTADOS: La mediana de la yoduria fue 197 μg/L. Tomaban suplementos yodados el 47% de las mujeres, con una mediana de yoduria superior a la de las que no tomaban suplementos yodados (247 vs 138 μg/L; <0,001) y también una TSH superior (2,30 vs 1,94 mU/L), aunque no significativamente diferente. La yoduria fue también superior en las mujeres que tomaban más de 2 raciones de productos lácteos (mediana: 230 μg/L) que en aquellas que tomaban menos de 2 raciones (mediana: 191 μg/L). Dentro del grupo de mujeres que no tomaban suplementos yodados, aquellas que utilizaban habitualmente sal yodada en la cocina (47%), tenían una mediana de yoduria de 190 μg/L, indicativa de suficiencia de yodo. CONCLUSIÓN: En la actualidad los suplementos yodados serían innecesarios en las mujeres embarazadas de nuestra entorno que consumen de forma habitual sal yodada y la recomendación en estos casos debería ser la de continuar utilizando la sal yodada en la cantidad recomendada en la gestación, así como consumir al menos dos raciones diarias de leche o productos lácteos

BACKGROUND AND OBJECTIVE: In Asturias, where iodine deficiency was eradicated in school children by the year 2000, iodine deficiency persisted in pregnant women, who were recommended to use of iodine supplementation. The aim of this study was to determine the iodine nutrition of pregnant women in our area and whether or not iodine supplements are needed. MATERIAL AND METHODS: Throughout May and June 2013 we studied the iodine nutrition and thyroid function during the first trimester of pregnancy in 173 women in the health area of Oviedo. RESULTS: The median urinary iodine was 197 μg/L. Iodinated supplements were used by 47% of women, which had a yoduria median higher than those not taking iodinated supplements (247 vs. 138 μg/L; p < .001), and also a higher TSH (2.30 vs 1.94 mU/L) although not significantly different. Yoduria was also higher in women who took more than 2 servings of dairy products (median: 230 μg/L) than those who took less (median: 191 μg/L). Within the group of women who were not taking iodine supplements, those regularly using iodized salt in the kitchen (47%) had a median urinary iodine concentration of 190 μg/L indicating iodine sufficiency. CONCLUSIONS: Iodinated supplements seem unnecessary nowadays in pregnant women of Oviedo who regularly take iodized salt and our recommendation in these cases should be to continue the use of iodized salt in the recommended amounts during pregnancy and consume at least two daily servings of milk or dairy products

Rotura hepática en paciente con preeclampsia severa y síndrome hellp / Hepatic rupture in a patient with severe pre-eclampsia and Hellp syndrome

La rotura hepática espontánea es una complicación rara y de alta mortalidad, asociado al síndrome Hellp y preeclampsia severa. La incidencia de rotura hepática varía de 1 en 45 000 a 1 en 225 000 de todos los embarazos. Se relata la experiencia institucional de manejo y tratamiento de la rotura hepática asociada a preeclampsia severa y síndrome Hellp, en una mujer de 29 años, con gestación de 39 semanas, que acudió a la emergencia por dinámica uterina. Luego de 3 horas presentó epigastralgia, dolor en brazo derecho y plaquetopenia, por lo que se decidió culminar el embarazo por cesárea, con recién nacido Ápgar 8 y 9; se evidenció hemoperitoneo y solución de continuidad de la cápsula de Glisson y hematoma hepático. Se realizó taponamiento hepático. Al cuarto día se reintervino para el retiro de gasas, con éxito y evolución favorable.

Spontaneous hepatic rupture is a rare complication with high mortality associated to Hellp syndrome and severe pre-eclampsia. Hepatic rupture incidence is 1 in 45 000 to 1 in 225 000 pregnancies. We present institutional experience in managing hepatic rupture associated to severe pre-eclampsia and Hellp syndrome in a 29 yearold woman with 39 weeks gestation admitted to emergency by uterine contractions. After three hours she presented epigastralgia, right arm pain and low platelets that led to emergency cesarean section with Apgar 8 and 9 newborn. Hemoperitoneum, discontinuity of Glisson’s capsule and hepatic hematoma were found. Hepatic tamponage was performed and removed the fourth day with successful evolution.

Epidemiología de las infecciones nosocomiales en un hospital de segundo nivel / Epidemiology of nosocomial infections at a secon level hospital

Objetivo. Conocer la incidecia, tasas específicas, áreas de mayor riesgo y los agentes causales de infecciones nosocomiales en el Hospital General de Durango, México, de la Secretaría de Salud. Material y métodos. Estudio prospectivo de vigilancia de infecciones nosocomiales, a lo largo de un año, que incluyó a todos los pacientes egresados durante ese periodo. Resultados. S encontró un tasa cruda de nueve infecciones por 100 egresos, las tasas específicas más altas correspondieron a la unidad de terapia intensiva pediátrica y neonatología y las más bajas a cirugía, pediatría y ginecobstetricia. Las infecciones de vías urinarias, neumonía y de heridas quirúrgicas fueron las más frecuentes en los servicios de adultos, mientras que las bacteremias mostraron una alta incidencia en las áreas pediátricas en donde se observó un brote epidémico donde predominó el germen Serratia marscecens. La mayoría de los pacientes presentaron un solo proceso infeccioso y E. coli, Klebsiella y Enterobacter spp. fueron los microrganismos más frecuentemente aislados. Conclusiones. La tasa de infecciones nosocomiales observada en este estudio es más alta que la informada en instituciones similares en México, y las áreas más afectadas fueron las de atención a pacientes en estado crítico y las de atención a recién nacidos, predominando la infección de vías urinarias, neumonía y de heridas quirúrgicas y como agentes causales los bacilos entéricos gram negativos. Los hallazgos anteriores sugieren pautas para el diseño e instrumentación de un programa de control de infecciones nosocomiales, ajustado a las características de este tipo de instituciones.
