Estudio de concordancia de radiografía-tomografía computarizada de las fracturas de radio distal / Radiography-computed tomography concordance study of distal radius fractures

Introducción: La fractura de radio distal resulta común en la extremidad superior y representa un reto terapéutico. Objetivo: Determinar la concordancia entre radiografía simple y tomografía computarizada con respecto a las clasificaciones AO Foundation y de Fernández, y la elección del tratamiento. Métodos: Se realizó un estudio de concordancia diagnóstica entre radiografía simple y tomografía computarizada. Ortopedistas y cirujanos de mano analizaron 19 imágenes de fracturas de radio distal de acuerdo con las clasificaciones AO Foundation y de Fernández, y las distintas opciones de tratamiento. Para el grado de concordancia se usó el coeficiente Kappa de Fleiss. La prueba de t-Student y Chi cuadrado diferenciaron los grupos para variables cuantitativas y cualitativas, respectivamente. Hubo una significancia estadística de p= 0,05. Resultados: La clasificación de Fernández coincidió mejor que la clasificación AO Foundation entre radiografía y tomografía computarizada. En la elección del tratamiento y la técnica de osteosíntesis la concordancia fue mayor al 90 por ciento, mientras que el abordaje quirúrgico solo alcanzó el 50 por ciento. La clasificación AO Foundation radiográfica se correspondió con fracturas complejas, mientras la de Fernández con las menos complicadas. Las fracturas se subestimaron cuando se clasificaron con radiografía. Conclusiones: La relación de las clasificaciones entre radiografía y tomografía computarizada para fracturas de radio distal no resulta satisfactoria. La tomografía computarizada ofrece información que modifica las decisiones en el tratamiento(AU)

Introduction: Distal radius fracture is common in the upper extremity and represents a therapeutic challenge. Objective: To determine the agreement between simple radiography and computed tomography with respect to AO Foundation and Fernández classifications, and the choice of treatment. Methods: A diagnostic agreement study was carried out between simple radiography and computed tomography. Orthopedists and hand surgeons analyzed 19 images of distal radius fractures according to AO Foundation and Fernández classifications, and the different treatment options. Fleiss Kappa coefficient was used for the degree of agreement. The Student's t-test and chi-square differentiated the groups for quantitative and qualitative variables, respectively. There was a statistical significance of p = 0.05. Results: Fernández classification coincided better than AO Foundation between radiography and computed tomography. In the choice of treatment and osteosynthesis technique, agreement was greater than 90 percent, while the surgical approach only reached 50 percent. The radiographic AO Foundation classification corresponded to complex fractures while Fernández classification corresponded to less complicated ones. Fractures were underestimated when classified with radiography. Conclusions: The relationship of classifications between radiography and computed tomography for distal radius fractures is not satisfactory. Computed tomography provides information that modifies treatment decisions(AU)

Nano solid phase micro membrane tip and electrochemical methods for vanillin analysis in chocolate samples.

A polymer-based nanosensor and electrochemical methods were developed for the quantitative analysis of vanillin. The sample preparation was done using nano solid phase micro membrane tip extraction (NSPMMTE). A novel poly(phenylalanine)/TiO2/CPE sensor was built as the working electrode for the first time for the analysis of the vanillin substance. The electrochemical behavior and analytical performance of vanillin were examined in detail by cyclic voltammetry (CV) and differential pulse stripping voltammetry (DPSV) techniques via the oxidation process. The optimized modules of the DPSV technique that affected the vanillin peak current and peak potential were pH, pulse amplitude, step potential, and deposition time. The electroactive surface areas of bare CPE, TiO2/CPE, and poly(phenylalanine)/TiO2/CPE electrodes were found to be 0.135 cm2, 0.155 cm2, and 0.221 cm2, respectively. The limit of detection (LOD) was 32.6 µg/L in the 0.25-15.0 mg/L working range at pH 7.0. The selectivity of the proposed DPSV method for the determination of vanillin on the modified electrode was investigated in the presence of various organic and inorganic substances, and the determination of vanillin with high recovery was achieved with less than 5% relative error. The analytical application was applied in chocolate samples and the DPSV method was found highly efficient, reproducible, and selective.

Measuring the impact of zero-cases studies in evidence synthesis practice using the harms index and benefits index (Hi-Bi).

OBJECTIVES: In evidence synthesis practice, dealing with studies with no cases in both arms has been a tough problem, for which there is no consensus in the research community. In this study, we propose a method to measure the potential impact of studies with no cases for meta-analysis results which we define as harms index (Hi) and benefits index (Bi) as an alternative solution for deciding how to deal with such studies. METHODS: Hi and Bi are defined by the minimal number of cases added to the treatment arm (Hi) or control arm (Bi) of studies with no cases in a meta-analysis that lead to a change of the direction of the estimates or its statistical significance. Both exact and approximating methods are available to calculate Hi and Bi. We developed the "hibi" module in Stata so that researchers can easily implement the method. A real-world investigation of meta-analyses from Cochrane reviews was employed to evaluate the proposed method. RESULTS: Based on Hi and Bi, our results suggested that 21.53% (Hi) to 26.55% (Bi) of Cochrane meta-analyses may be potentially impacted by studies with no cases, for which studies with no cases could not be excluded from the synthesis. The approximating method shows excellent specificity (100%) for both Hi and Bi, moderate sensitivity (68.25%) for Bi, and high sensitivity (80.61%) for Hi compared to the exact method. CONCLUSIONS: The proposed method is practical and useful for systematic reviewers to measure whether studies with no cases impact the results of meta-analyses and may act as an alternative solution for review authors to decide whether to include studies with no events for the synthesis or not.

Interventions for osteoarthritis pain: A systematic review with network meta-analysis of existing Cochrane reviews.

Objective: To conduct a network meta-analysis comparing all treatments for osteoarthritis (OA) pain in the Cochrane Library. Design: The Cochrane Library and Epistemonikos were searched for randomized controlled trials (RCTs) about treatments for hip and knee OA. We constructed 17 broad categories, comprising drug treatments, exercise, surgery, herbs, orthotics, passive treatments, regenerative medicine, diet/weight loss, combined treatments, and controls. In addition to a full network analysis, we compared the direct/indirect effects, and studies with shorter-/longer follow-up. CINeMA software was used for assessing confidence in network meta-analysis estimates. Results: We included 35 systematic reviews including 445 RCTs. There were 153 treatments for OA. In total, 491 comparisons were related to knee OA, less on hip OA, and only nine on hand OA. Six treatment categories showed clinically significant effects favoring treatment over control on pain. "Diet/weight loss" and "Surgery" had effect sizes close to zero. The network as a whole was not coherent. Of 136 treatment comparisons, none were rated as high confidence, six as moderate, 13 as low, and 117 as very low. Conclusions: Direct comparison of different available treatment options for OA is desirable, however not currently feasible in practice, due to heterogeneous study populations and lack of clear descriptions of control interventions. We found that many treatments were effective, but since the network as a whole was not coherent and lacked high confidence in the treatment comparisons, we could not produce a ranking of effects.

Two-year results of a novel sutureless scleral fixation surgery with the haptic hook technique.

PURPOSE: In this study, we evaluated the visual results and complication rates of the novel technique of sutureless scleral fixated intraocular lens (SFIOL) surgery in patients without capsular support. METHODS: In this retrospective study, patients who did not have adequate capsular support and who underwent sutureless SFIOL between 2013 and 2017 at the University of Health Science Dr. Lütfi Kirdar Kartal Training and Research Hospital's Eye Clinic were included. Preoperative and postoperative best corrected visual acuity (BCVA), perioperative and postoperative complications, surgical indications, previous surgeries, and surgical procedures were evaluated. RESULTS: The study included 131 eyes of 162 patients who underwent sutureless SFIOL surgery. Thirty-one patients were excluded from the study because of missing data. The mean age of the patients was 61.5 ± 23.2 years, 72 of whom were female, and the mean follow-up period was 24.3 ± 11.4 months. When all the patients were evaluated together, the preoperative mean BCVA was 1.11 ± 1.01, 0.86 ± 0.76 in the first month, 0.71 ± 0.69 in the third month, and 0.60 ± 0.50 in the second year after surgery according to logMAR. CONCLUSION: The 2-year results of our study demonstrate that the haptic hook technique for sutureless SFIOL surgery is effective and safe in aphakia rehabilitation. However, haptic hooks and their associated future complications must be monitored for a longer period of time to reach a definite conclusion.

Validity of the Pulmonary Embolism Rule-Out Criteria (PERC) for ruling out pulmonary embolism in low-risk patients at high altitudes

Abstract Objectives: to validate the diagnostic yield of the PERC score for ruling out pulmonary embolism in low-risk patients at high altitudes (>2500 meters above sea level [ASL]). Methods: a cross-sectional study with diagnostic test analysis in patients over the age of 18 with suspected pulmonary embolism on admission or during hospitalization, who underwent chest computed tomography angiography between August 2009 and January 2020 in a tertiary care hospital located on the Bogotá savannah. The yield of the PERC score was assessed, calculated with an SaO2<95% and an SaO2<90% in patients with different risk levels according to the Wells, Geneva and Pisa scores for pulmonary embolism. Results: one thousand eighty-seven were included in the final analysis, 42% with PE. Patients classified as low-risk using the Wells score had a PERC ACOR calculated with SaO2<95% of 0.56 (95%CI:0.50-0.62) (p=0.049), and calculated with SaO2<90% of 0.60 (95%CI:0.54-0.66) (p=0.002). The ACOR for subjects classified as low-risk using the Geneva score, with a PERC calculated with SaO2<95%, was: 0.53 (95%CI:0.45-0.60) (p=0.459) and for a PERC calculated with SaO2<90% it was: 0.55 (95%CI:0.47-0.62) (P=0.218). The ACOR for subjects with a less than 10% probability of PE according to the Pisa score classification, with a PERC calculated with SaO2<95%, was: 0.54 (95%CI:0.44-0.64)(p=0.422), and for a PERC calculated with SaO2<90% it was: 0.56 (95%CI:0.46-0.66)(p=0.236). Conclusions: the PERC score calculated with an oxygen saturation <90% has a similar diagnostic yield to the PERC score calculated with an oxygen saturation <95% for ruling out PE in patients classified as low-risk by the Wells score at high altitudes (>2,500 meters ASL).

Bridging Captive and Wild Studies: Behavioral Plasticity and Social Complexity in Theropithecus gelada.

Cognitive ethology explores the ability of animals to flexibly adapt their behavior to rapid physical and social environment fluctuations. Although there is a historical dichotomy between field and captive studies, recently, a growing interest in questions that sit at the intersection of cognitive and adaptive perspectives has helped bridge this divide. By focusing on Theropithecus gelada, we discuss the three main reasons why this hybrid approach is extremely successful. First, captive and wild studies provide data at different social, spatial, and temporal scales that can be synthesized to give a fuller picture of the behavior. Secondly, apparently conflicting results from captive and wild settings are powerful tools to explore behavioral flexibility and latent behavioral tendencies. Third, the different settings provide ways of validating and exploring behaviors that are noticed in the other setting. Although we were able to bring together our captive and wild research to demonstrate these ideas, we could have obtained a more integrated vision on the proximate and ultimate gelada behavioral and cognitive strategies if we had considered this hybrid approach from the beginning. We hope that this manuscript stimulates scholars in designing their studies by taking into account the incredible potential of a complementary captive-wild research approach.

Does reading a book in bed make a difference to sleep in comparison to not reading a book in bed? The People's Trial-an online, pragmatic, randomised trial.

BACKGROUND: The best way of comparing healthcare treatments is through a randomised trial. In a randomised trial, we compare something (a treatment or intervention) to something else, often another treatment. Who gets what is decided at random, meaning everyone has an equal chance of getting any of the treatments. This means any differences found can be put down to the treatment received rather than other things, such as where people live, or health conditions they might have. The People's Trial aimed to help the public better understand randomised trials by inviting them to design and carry out a trial. The question chosen by the public for The People's Trial was: 'Does reading a book in bed make a difference to sleep, in comparison to not reading a book in bed?' This paper describes that trial, called 'The Reading Trial'. METHODS: The Reading Trial was an online, randomised trial. Members of the public were invited to take part through social media campaigns. People were asked to either read a book in bed before going to sleep (intervention group) or not read a book in bed before going to sleep (control group). We asked everyone to do this for 7 days, after which they measured their sleep quality. RESULTS: During December 2019, a total of 991 people took part in The Reading Trial, half (496 (50%)) in the intervention group and half (495 (50%)) in the control group. Not everyone finished the trial: 127 (25.6%) people in the intervention group and 90 (18.18%) people in the control group. Of those providing data, 156/369 (42%) people in the intervention group felt their sleep improved, compared to 112/405 (28%) of those in the control group, a difference of 14%. When we consider how certain we are of this finding, we estimate that, in The Reading Trial, sleep improved for between 8 and 22% more people in the intervention group compared to the control group. CONCLUSIONS: Reading a book in bed before going to sleep improved sleep quality, compared to not reading a book in bed. TRIAL REGISTRATION: ClinicalTrials.gov NCT04185818. Registered on 4 December 2019.

Development and Validation of a Comprehensive Neuropsychological and Language Rehabilitation for Stroke Survivors: A Home-Based Caregiver-Delivered Intervention Program.

CONTEXT: Aphasia is a major disabling condition after a stroke that profoundly affects the quality of life of stroke survivors (SS) and their caregivers. Comprehensive neuropsychological rehabilitation has emerged as a complementary intervention that helps in improving the associated cognitive and psychological deficits and quality of life following a brain injury. A standardized, simple, and easy to administer intervention that can be delivered as a home-based intervention can assist in faster recovery. AIMS: To describe the development, validation, and feasibility of a home-based, caregiver-delivered comprehensive neuropsychological and language rehabilitation for SS. METHODS AND MATERIAL: A culture-specific picture and task-based 8-week training workbook and manual were developed based on extensive review and focused group discussions. This intervention targeted areas of language (comprehension, fluency, and naming) and cognition (working memory, attention and concentration, executive functioning, and response inhibition). It was standardized on 40 healthy controls (HC) and 15 SS. Before recruitment, written informed consent was obtained from each patient, their primary caregiver, and the HCs. RESULTS: All tasks were found to be effective in discriminating the performance of SS from the HC. The performance of the HC with respect to the errors and the time taken for each task was used for the hierarchical arrangement of the tasks. The developed intervention was later validated on 15 SS where they significantly improved in the pre-post assessment of language functioning (P < 0.001), quality of life (P < 0.001), and depression (P < 0.001). CONCLUSIONS: This intervention can be feasible to administer as a home-based intervention and may help to alleviate language and neuropsychological complaints after stroke in low-literate or mixed-cultural populations. Further, large sample size studies are recommended.

Psychometric Properties of the Functional Social Support Domain of Perinatal Infant Care Social Support.

OBJECTIVES: To determine the face, content, construct validity, and reliability of the functional social support domain of Perinatal Infant Care Social Support (PICSS) translated into Spanish and adapted for first-time mothers of term babies. METHODS: Validation study of the functional social support domain of PICSS, which has 22 items with response options from 1 to 4; higher scores indicate greater social support. A translation, back-translation, and cultural adaptation process took place along with an expert review to evaluate face and content validity. In total, 210 mothers participated to establish construct validity and the reliability of the domain. The content validity index and factor analysis were used to identify the structure of the domain. Reliability was estimated using Cronbach's alpha coefficient. RESULTS: Linguistic and cultural adaptations were performed, along with validation and reliability. Face validity for mothers was the following: high comprehension (94%); and for experts: high comprehension (95.83%), high clarity (96.53%), and high precision (92.82%). In relevance and pertinence, the content validity index was high (0.97). Construct validation identified two factors that explained 76% of the variance of the domain evaluated: factor 1 "Supporting presence -emotional and appraisal support" (13 items, 39%) and factor 2 "Practical support -informational and instrumental support-" (9 items, 37%). Cronbach's alpha value was 0.97. CONCLUSIONS: Given the robust psychometric properties of the Spanish version of the functional social support domain of PICSS, this may be used to identify the functional social support in the mothers.

Vitrification Using Soy Lecithin and Sucrose: A New Way to Store the Sperm for the Preservation of Canine Reproductive Function.

A challenge in freezing semen for short and long-term availability is avoiding damage to intact spermatozoa caused by the freezing process. Vitrification protocols provide better results through less manipulation of semen and shorter freezing time compared to slow freezing techniques. Our research was aimed at improving vitrification methods for canine semen. Semen quality was determined in 20 ejaculates after collection. Each ejaculate was divided into eight aliquots, each with a different extender. The control extender contained TRIS, citric acid, fructose, and antibiotics. Soy lecithin and sucrose were added to the control extender at different concentrations to make up the test extenders and final concentration of 50 × 106 spermatozoa/mL. From each group, a 33µL (1.65 × 106 spermatozoa) suspension of spermatozoa was dropped directly into liquid nitrogen and devitrified at least one week later and evaluated as before. Soy lecithin at 1% and 0.25 M sucrose added to the base vitrification media effectively preserved all sperm qualities. Our results demonstrate the effectiveness of our methods. Vitrification media containing sucrose and soy lecithin cause a minimal decline in quality of canine semen after devitrification. Furthermore, extenders used in our research did not contain egg yolk, which was replaced by soy lecithin, thus allowing for ease of shipping to other countries with strict requirements.

Structural and socio-cultural barriers to accessing mental healthcare among Syrian refugees and asylum seekers in Switzerland.

Background: Due to their experiences of major stressful life events, including post-displacement stressors, refugees and asylum seekers are vulnerable to developing mental health problems. Yet, despite the availability of specialized mental health services in Western European host countries, refugees and asylum seekers display low mental healthcare utilization. Objective: The aim of this study was to explore structural and socio-cultural barriers to accessing mental healthcare among Syrian refugees and asylum seekers in Switzerland. Method: In this qualitative study, key-informant (KI) interviews with Syrian refugees and asylum seekers, Swiss healthcare providers and other stakeholders (e.g. refugee coordinators or leaders) were conducted in the German-speaking part of Switzerland. Participants were recruited using snowball sampling. Interviews were audiotaped and transcribed, and then analysed using thematic analysis, combining deductive and inductive coding. Results: Findings show that Syrian refugees and asylum seekers face multiple structural and socio-cultural barriers, with socio-cultural barriers being perceived as more pronounced. Syrian key informants, healthcare providers, and other stakeholders identified language, gatekeeper-associated problems, lack of resources, lack of awareness, fear of stigma and a mismatch between the local health system and perceived needs of Syrian refugees and asylum seekers as key barriers to accessing care. Conclusions: The results show that for Syrian refugees and asylum seekers in Switzerland several barriers exist. This is in line with previous findings. A possible solution for the current situation might be to increase the agility of the service system in general and to improve the willingness to embrace innovative paths, rather than adapting mental healthcare services regarding single barriers and needs of a new target population.

Revista Europea de PsicotraumatologíaAntecedentes: Debido a sus experiencias de eventos vitales estresantes mayores, incluidos los estresores posteriores al desplazamiento, los refugiados y solicitantes de asilo son vulnerables a desarrollar problemas de salud mental. Sin embargo, a pesar de la disponibilidad de servicios especializados de salud mental en los países hospedadores de Europa occidental, los refugiados y los solicitantes de asilo muestran una baja utilización de cuidados salud mental.Objetivo: El objetivo de este estudio fue explorar las barreras estructurales y socioculturales para acceder a cuidados de salud mental para refugiados y solicitantes de asilo sirios, en Suiza.Método: En este estudio cualitativo, se realizaron entrevistas informante-clave (IC) con refugiados y solicitantes de asilo sirios, proveedores de cuidados de salud suizos y otros grupos de interes (por ejemplo, coordinadores o líderes de refugiados) en la parte de habla alemana de Suiza. Los participantes fueron reclutados mediante muestreo de bola de nieve. Las entrevistas fueron grabadas en audio y transcritas, y luego analizadas mediante análisis temático, combinando codificación deductiva e inductiva.Resultados: Los resultados muestran que los refugiados y solicitantes de asilo sirios, enfrentan múltiples barreras estructurales y socioculturales, siendo las socio-culturales percibidas como más pronunciadas. Los informantes-clave sirios, los proveedores de cuidados de salud y otras grupos de interes, identificaron el idioma, problemas asociados con la puerta de entrada a las instituciones, falta de recursos, falta de conciencia, miedo al estigma y discordancia entre el sistema de salud local y las necesidades percibidas de los sirios refugiados y solicitantes de asilo como barreras clave para acceder a la atención.Conclusiones: Los resultados muestran que para los refugiados y solicitantes de asilo sirios en Suiza existen varias barreras. Esto está en línea con hallazgos previos. Una posible solución para la situación actual podría ser aumentar la agilidad del sistema de servicios en general y mejorar la disposición a adoptar caminos innovadores, en lugar de adaptar los servicios de salud mental con respecto a las barreras y necesidades individuales de una nueva población objetivo.

Intergenerational consequences of the Holocaust on offspring mental health: a systematic review of associated factors and mechanisms.

Exposure to war and violence has major consequences for society at large, detrimental impact on people's individual lives, and may also have intergenerational consequences. To gain more insight into these intergenerational consequences, research addressing the impact of the Holocaust on offspring is an important source of information. The aim of the current study was to systematically review the mechanisms of intergenerational consequences by summarizing characteristics in Holocaust survivors and their offspring suggested to impact the offspring's mental health. We focused on: 1) parental mental health problems, 2) (perceived) parenting and attachment quality, 3) family structure, especially parental Holocaust history, 4) additional stress and life events, and 5) psychophysiological processes of transmission. We identified 23 eligible studies published between 2000 and 2018. Only Holocaust survivor studies met the inclusion criteria. Various parent and child characteristics and their interaction were found to contribute to the development of psychological symptoms and biological and epigenetic variations. Parental mental health problems, perceived parenting, attachment quality, and parental gender appeared to be influential for the mental well-being of their offspring. In addition, having two survivor parents resulted in higher mental health problems compared to having one survivor parent. Also, there was evidence suggesting that Holocaust survivor offspring show a heightened vulnerability for stress, although this was only evident in the face of actual danger. Finally, the results also indicate intergenerational effects on offspring cortisol levels. Clinical and treatment implications are discussed.

La exposición a la guerra y la violencia tiene consecuencias importantes para la sociedad en general, un impacto perjudicial en la vida individual de las personas, y también puede tener consecuencias intergeneracionales. Para obtener más información sobre estas consecuencias intergeneracionales, la investigación que aborda el impacto del Holocausto en la descendencia es una fuente importante de información. El objetivo del presente estudio fue revisar sistemáticamente los mecanismos de las consecuencias intergeneracionales resumiendo las características de los sobrevivientes del Holocausto y sus descendientes, que podrían impactar la salud mental de la descendencia. Nos centramos en: 1) los problemas de salud mental de los padres, 2) la calidad (percibida) de la crianza y el apego, 3) la estructura familiar, especialmente antecedentes del Holocausto de los padres, 4) el estrés y los eventos de la vida adicionales, y 5) los procesos psicofisiológicos de la transmisión. Identificamos 23 estudios elegibles publicados entre 2000 y 2018. Solo los estudios de sobrevivientes del Holocausto cumplieron con los criterios de inclusión. Se descubrió que diversas características de los padres y de los hijos y su interacción contribuyen al desarrollo de los síntomas psicológicos y las variaciones biológicas y epigenéticas. Los problemas de salud mental de los padres, la crianza percibida, la calidad del apego, y el género parental parecieron influir en el bienestar mental de sus hijos. Además, tener dos padres sobrevivientes resultó en mayores problemas de salud mental en comparación con tener uno de los padres sobrevivientes. Además, hubo evidencia que sugiere que los descendientes de los sobrevivientes del Holocausto muestran una mayor vulnerabilidad al estrés, aunque esto fue solo evidente ante el peligro real. Finalmente, los resultados también indican los efectos intergeneracionales en los niveles de cortisol de la descendencia. Se discuten las implicaciones clínicas y de tratamiento.

Stereotactic Body Radiotherapy - Current Indications.

BACKGROUND: Stereotactic body radiotherapy (SBRT) is used to treat localized tumor lesions and consists of applying high doses of radiation to a small number of fractions using specially equipped linear accelerators, modern immobilization devices, and imaging methods, which are considered special, advanced techniques in modern day radiotherapy. SBRT is a very well tolerated, non-invasive, short-term treatment that does not require hospitalization or any complicated preparation. Compared to standard radiotherapy techniques, SBRT allows, due to its precision, significantly higher doses to be applied to the target with less damage to surrounding healthy tissues. If dose constraints are not exceeded, the risk of damage to tissues and organs around the irradiated volume is reduced to minimum. The principle of SBRT is the application of ablative doses of radiation that cause necrosis of the irradiated tissue. PURPOSE: The aim of this review is to provide a basic overview of SBRT indications, radiation doses used, and potential side effects. It is not intended to be a detailed description of treatment itself (such as discussion of patient fixation systems, management of respiratory movements, or image guided strategies of treatment). This review also discusses rarer indications for SBRT, such as pancreatic carcinoma or hepatocellular carcinoma. CONCLUSION: Advances in image navigation, radiation planning, and dose application have enabled successful introduction of SBRT as a treatment regimen for many primary tumors and oligometastatic disease. If surgery is not possible or the patient refuses surgery, it is always reasonable to consider SBRT. SBRT has curative potential for the treatment of primary lung or prostate tumors. High-dose irradiation of oligometastases of various primary tumors can lead to long-term survival without disease symptoms, delay administration of toxic systemic therapies, and improve the quality of life of oncological patients.

Use of Salivary MicroRNAs for Diagnosis of Solid Cancers.

BACKGROUND: A modern approach to identify biomarkers of solid cancers in tissues and body fluids is based on microRNA (miRNA) expression profiling. miRNAs are a group of approximately 3.000 short noncoding RNAs containing 18-25 nucleotides that regulate gene expression at the post-transcriptional (mRNA) level. The abilities of miRNAs to inhibit the translation or induce degradation of oncogenes and tumor suppressors indicate that they are involved in carcinogenesis. There is increasing evidence that miRNAs regulate apoptosis, cell proliferation, differentiation, and invasion. miRNA expression profiles are therefore often analyzed for molecular diagnostics of solid cancers, similar to analyses based on mRNA profiling. It is important that miRNAs are highly stable and present at high levels in body fluids, including saliva, for analytic usage. miRNAs in saliva have been successfully tested as potential diagnostic biomarkers of many solid cancers. The main advantage of these miRNAs is that saliva samples can be collected non-invasively. AIM: This review aims to summarize current knowledge of circulating miRNAs in solid cancers, with a focus on the use of miRNAs in saliva for oncology diagnostics. Key words: microRNA - saliva - diagnosis - cancer The results of this research have been acquired within CEITEC 2020 (LQ1601) project with fi nancial contribution made by the Ministry of Education, Youths and Sports of the Czech Republic within special support paid from the National Programme for Sustainability II funds.

Exploring resilience models in a sample of combat-exposed military service members and veterans: a comparison and commentary.

Background: The term resilience is applied in numerous ways in the mental health field, leading to different perspectives of what constitutes a resilient response and disparate findings regarding its prevalence following trauma. Objective: illustrate the impact of various definitions on our understanding and prevalence of resilience, we compared various resilience definitions (absence of PTSD, absence of current mental health diagnosis, absence of generalized psychological distress, and an alternative trauma load-resilience discrepancy model of the difference between actual and predicted distress given lifetime trauma exposure) within a combat-exposed military personnel and veteran sample. Method: In this combat-trauma exposed sample (N = 849), of which approximately half were treatment seeking, rates of resilience were determined across all models, the kappa statistic was used to determine the concordance and strength of association across models, and t-tests examined the models in relation to a self-reported resilience measure. Results: Prevalence rates were 43.7%, 30.7%, 87.4%, and 50.1% in each of the four models. Concordance analyses identified 25.7% (n = 218) considered resilient by all four models (kappa = .40, p < .001). Correlations between models and self-reported resilience were strong, but did not fully overlap. Conclusions:The discussion highlights theoretical considerations regarding the impact of various definitions and methodologies on resilience classifications, links current findings to a systems-based perspective, and ends with suggestions for future research approaches on resilience.

Antecedentes: El término resiliencia se ha aplicado de muchas maneras en el campo de la salud mental, llevando a diferentes perspectivas de lo que constituye una respuesta resiliente y hallazgos dispares relacionados a la prevalencia después de un trauma. Objetivos: Para Ilustrar el impacto de las diversas definiciones en nuestra compresión y prevalencia de la resiliencia, comparamos varias definiciones de resiliencia (ausencia de TEPT, ausencia de un diagnóstico de salud mental actual, ausencia de malestar psicológico generalizado, y un modelo alternativo de discrepancia entre la carga y la resiliencia del trauma de la diferencia entre la angustia real y la prevista dada la exposición al trauma a lo largo de la vida) entre personal militar expuesto a combate y una muestra de veteranos. Método: En esta muestra expuesta a trauma de combate (N= 849), de la cual aproximadamente la mitad estaba en búsqueda de tratamiento, las tasas de resiliencia se determinaron en todos los modelos, el kappa estadístico se usó para determinar la concordancia y la fuerza de asociación en todos los modelos, y el t-test examinó los modelos en relación a la medida de resiliencia auto-reportada. Resultados: La tasas de prevalencia variaron desde 43,7%, 30,7%, 87,4% y 50,1% en los cuatro modelos respectivamente. El análisis de concordancia identificó un 25,7% (n=218) considerado resiliente por los cuatro modelos (kappa= .40, p< .001). Las correlaciones entre los modelos y la resiliencia auto-reportada fueron fuertes, pero no se superpusieron por completo. Conclusiones: la discusión resalta las consideraciones teóricas sobre el impacto de las distintas definiciones y metodologías sobre las clasificaciones de resiliencia, vincula el hallazgo actual con una perspectiva basada en sistemas y finaliza con sugerencias para futuros enfoques de investigación en resiliencia.

Dissociative symptoms mediate the relation between PTSD symptoms and functional impairment in a sample of military members, veterans, and first responders with PTSD.

Background: Posttraumatic Stress Disorder (PTSD) is associated with significant functional impairment in important areas, including interpersonal relationships and occupational or educational roles. Preliminary evidence suggests that the dissociative subtype of PTSD (PTSD+DS), characterized by marked symptoms of depersonalization and derealization, is associated with increased functional impairment and disease severity, including among military members and veterans diagnosed with PTSD. Similarly, first responders (e.g. police, fire, paramedics) have also been found to experience dissociative symptoms. Despite these findings, little work has investigated whether dissociative symptoms are related to heightened functional impairment among these populations. Objective: We examined the relation between functional impairment and symptom level variables, including dissociative symptoms of depersonalization and derealization among military members, veterans, and first responders with probable PTSD. We further investigated the hypothesis that dissociative symptoms mediate the relation between PTSD symptomatology and functional impairment. Method: Eighty-one medical charts of inpatients at a residential PTSD treatment programme were accessed via retrospective review. Sixty-two were included in the present analyses. Comparison of means on symptom measures between first responders and military members/veterans were conducted, followed by correlational and mediation analyses. Results: Compared with first responders, military members and veterans showed higher levels of derealization, functional impairment, alexithymia, anxiety, and depression. Within the total sample, dissociative symptoms emerged as the strongest correlate of functional impairment and, among the dissociative symptom clusters, derealization symptoms demonstrated the strongest relation with impairment. Mediation analyses revealed that total dissociative symptoms and derealization symptoms significantly mediated the relation between PTSD symptoms and functional impairment. Conclusions: These findings highlight the importance of assessing and treating dissociative symptoms, consistent with the dissociative subtype of PTSD, among military members, veterans, and first responders with PTSD. Successful recovery on a functional and symptomatic level may necessitate treatment of dissociative symptoms, particularly derealization.

Planteamiento: El trastorno por estrés postraumático (TEPT) se asocia con un deterioro funcional significativo en áreas importantes, incluidas las relaciones interpersonales y los roles ocupacionales o educativos. La evidencia preliminar sugiere que el subtipo disociativo de TEPT (TEPT + SD), caracterizado por síntomas marcados de despersonalización y desrealización, se asocia con mayor deterioro funcional y gravedad de la enfermedad, incluso entre miembros militares y veteranos diagnosticados con TEPT. Del mismo modo, también se ha encontrado que los profesionales en intervención inmediata (por ejemplo, policías, bomberos, paramédicos) también experimentan síntomas disociativos. A pesar de estos hallazgos, pocos han investigado si los síntomas disociativos están relacionados con una mayor deficiencia funcional entre estas poblaciones.Objetivo: Examinamos la relación entre el deterioro funcional y las variables de nivel de síntomas, incluyendo síntomas disociativos de despersonalización, desrealización entre miembros militares, veteranos y profesionales en intervención inmediata con un probable TEPT. Además investigamos la hipótesis de que los síntomas disociativos median la relación entre la sintomatología del TEPT y el deterioro funcional.Método: Se accedió a ochenta y un historiales clínicos de pacientes hospitalizados en un programa residencial de tratamiento de TEPT mediante un análisis retrospectivo. Sesenta y dos fueron incluidos en el presente análisis. Se realizó una comparación de los medios de medición de síntomas entre los profesionales en intervención inmediata y los militares y veteranos, seguida de análisis de correlación y mediación.Resultados: En comparación con los profesionales en intervención inmediata los miembros del ejército y los veteranos mostraron niveles más altos de desrealización, deterioro funcional, alexitimia, ansiedad y depresión.Dentro de la muestra total, los síntomas disociativos surgieron como el correlato más fuerte del deterioro funcional y, entre los grupos de síntomas disociativos, los síntomas de desrealización mostraron la relación más fuerte con el deterioro. Los análisis de mediación revelaron que los síntomas disociativos totales y los síntomas de desrealización mediaban significativamente en la relación entre los síntomas de TEPT y el deterioro funcional.Conclusiones: Estos hallazgos resaltan la importancia de evaluar y tratar los síntomas disociativos, coincidentes con el subtipo disociativo del TEPT, entre los militares, los veteranos y los profesionales en intervención inmediata con TEPT. El éxito de su recuperación a nivel funcional y sintomático puede requerir el tratamiento de los síntomas disociativos, en particular, la desrealización.

Posttraumatic stress and depressive symptoms in children after the Wenchuan earthquake.

Background: Many studies have reported the comorbidity of posttraumatic stress disorder (PTSD) and depression in children. However, the underlying relationship between PTSD and depression remains unclear. Objective: This study examines the relationship between PTSD and depressive symptoms in children who survived the Wenchuan earthquake in China. Methods: In total, 301 children were assessed at four months and then followed up at 29, 40 and 52 months after the disaster. The ages of the children ranged from 9.6-14.6 years old, and the sample included 157 males and 144 females. The children were assessed by using the University of California at Los Angeles PTSD reaction index for DSM-IV for PTSD symptoms and the Children's Depression Inventory for depressive symptoms. Results: Comorbid PTSD and depressive symptoms were prevalent in 4.0, 3.3, 3.7 and 5.1% of the participants at times 1, 2, 3 and 4, respectively. The cross-lagged analysis indicated that PTSD symptoms at time 1 predicted depressive symptoms at time 2; depressive symptoms at time 1 predicted PTSD symptoms at time 2; depressive symptoms at time 2 predicted PTSD symptoms at time 3; and depressive symptoms at time 3 predicted PTSD symptoms at time 4. The findings also showed that being female, poor parental relationships and trauma exposure were risk factors for PTSD or depressive symptoms. Conclusions: The results suggest that the causal relationship between PTSD and depressive symptoms changes over time; the effects of PTSD symptoms tend to decrease, while those of depressive symptoms tend to increase. Two stages of the relationship between PTSD and depressive symptoms were observed, namely, that PTSD and depressive symptoms first influenced each other and then that depressive symptoms predicted PTSD. The results of our study also suggest that females with poor parental relationships and a high degree of trauma exposure are more likely to require intervention.

Antecedentes: Muchos estudios han reportado la comorbilidad del trastorno de estrés postraumático (TEPT) y depresión en niños. Sin embargo, la relación subyacente entre TEPT y depresión permanece poco clara.Objetivo: Este estudio examina la relación entre TEPT y síntomas depresivos en niños que sobrevivieron al terremoto de Wenchuan en China.Métodos: En total, 301 niños fueron evaluados a los 4 meses y luego en seguimiento a los 29, 40 y 52 meses después del desastre. Los rangos de edades de los niños fueron entre 9,6-14,6 años y la muestra incluyó 157 hombres y 144 mujeres. Los niños fueron evaluados usando el índice de reacción de TEPT de la Universidad de California en Los Ángeles para los síntomas de TEPT según el DSM-IV y para los síntomas depresivos el Inventario de Depresión para Niños.Resultados: La comorbilidad TEPT y síntomas depresivos tuvieron una prevalencia de un 4,0%, 3,3%, 3,7% y 5,1% de los participantes a los tiempos 1, 2, 3 y 4, respectivamente. El análisis cruzado indicó que los síntomas de TEPT en el tiempo 1 predijo los síntomas depresivos al tiempo 2, y que los síntomas depresivos al tiempo 1 predijeron síntomas de TEPT al tiempo 2; los síntomas depresivos al tiempo 2 predijeron síntomas de TEPT al tiempo 3; y síntomas depresivos al tiempo 3 predijeron síntomas de TEPT al tiempo 4. Los hallazgos también mostraron que ser mujer, malas relaciones parental y exposición a trauma fueron factores de riesgo para TEPT o síntomas depresivos.Conclusiones: Los resultados sugieren que la relación causal entre TEPT y síntomas depresivos cambia en el tiempo; los efectos de los síntomas de TEPT tienden a disminuir, mientras que los síntomas depresivos tienden a aumentar. Se observaron dos estadíos de relación entre los síntomas de TEPT y depresivos, esto es, que primero el TEPT y síntomas depresivos se influyen mutuamente y luego, los síntomas depresivos predijeron el TEPT. Los resultados de nuestro estudio también sugieren que las niñas con malas relaciones parentales y alto grado de exposición a trauma son las que probablemente requieren mayor intervención.

Intensive prolonged exposure therapy for chronic PTSD patients following multiple trauma and multiple treatment attempts.

Background: Suboptimal response and high dropout rates leave room for improvement of trauma-focused treatment (TFT) effectiveness in ameliorating posttraumatic stress disorder (PTSD) symptoms. Objective: To explore the effectiveness and safety of intensive prolonged exposure (iPE) targeting chronic PTSD patients with a likely diagnosis of ICD-11 Complex PTSD following multiple interpersonal trauma and a history of multiple treatment attempts. Method: Participants (N = 73) received iPE in 12 × 90-minute sessions over four days (intensive phase) followed by four weekly 90-minute booster prolonged exposure (PE) sessions (booster phase). The primary outcomes, clinician-rated severity of PTSD symptoms, and diagnostic status (Clinician-Administered PTSD Scale; CAPS-IV) were assessed at baseline, post-treatment, and at three and six months. Treatment response trajectories were identified and predictors of these trajectories explored. Results: Mixed model repeated measures analysis of CAPS-IV scores showed a baseline-to-posttreatment decrease in PTSD symptom severity (p < .001) that persisted during the three- and six-month follow-ups with large effect sizes (Cohen's d > 1.2); 71% of the participants responded. None of the participants dropped out during the intensive phase and only 5% during the booster phase. Adverse events were extremely low and only a minority showed symptom exacerbation. Cluster analysis demonstrated four treatment response trajectories: Fast responders (13%), Slow responders (26%), Partial responders (32%), and Non-responders (29%). Living condition and between-session fear habituation were found to predict outcome. Participants living alone were more likely to belong to the Partial responders than to the Non-responders cluster, and participants showing more between-session fear habituation were more likely to belong to the Fast responders than to the Non-responders cluster. Conclusions: The results of this open study suggest that iPE can be effective in PTSD patients with multiple interpersonal trauma and after multiple previous treatment attempts. In addition, in this chronic PTSD population iPE was safe.

Planteamiento: La respuesta subóptima y las altas tasas de abandono dejan margen para la mejora de la eficacia del tratamiento centrado en el trauma (TCT) en la mejora de los síntomas del trastorno por estrés postraumático (TEPT). Objetivo: explorar la efectividad y la seguridad de la exposición prolongada intensiva (EPI) dirigida a pacientes con TEPT crónico con un probable diagnóstico de TEPT complejo de la CIE-11 después de múltiples traumas interpersonales y un historial de múltiples intentos de tratamiento. Método: Los participantes (N = 73) recibieron EPI en 12 sesiones de 90 minutos durante cuatro días (fase intensiva) seguidas de cuatro sesiones semanales de exposición prolongada (EP) de refuerzo de 90 minutos (fase de refuerzo). Los resultados principales, la gravedad de los síntomas del TEPT evaluados por el clínico y el estado diagnóstico evaluados por el clínico (Escala de TEPT administrada por el clínico, CAPS-IV, por sus siglas en inglés) se evaluaron al inicio, después del tratamiento, y a los tres y seis meses. Se identificaron las trayectorias de respuesta al tratamiento y se exploraron los predictores de estas trayectorias. Resultados: Los análisis de medidas repetidas de las puntuaciones de CAPS-IV desde un modelo mixto mostraron una disminución de la línea de base hasta el postratamiento en cuanto a la gravedad de los síntomas de TEPT (p <.001) que persistió durante los seguimientos a los 3 y 6 meses con tamaños de efecto grandes (d de Cohen> 1,2); el 71% de los participantes respondieron. Ninguno de los participantes abandonó durante la fase intensiva y solo el 5% lo hizo durante la fase de refuerzo. Los eventos adversos fueron extremadamente bajos y solo una minoría mostró exacerbación de los síntomas. El análisis de clusters demostró cuatro trayectorias de respuesta al tratamiento: los que responden rápidamente (13%), los que responden lentamente (26%), los que responden parcialmente (32%) y los que no responden (29%). Se descubrió que las condiciones de vida y la habituación al miedo entre sesiones predecían el resultado. Los participantes que vivían solos eran más propensos a pertenecer a los que responden parcialmente que al grupo de los que no responden, y los participantes que demostraron más habituación al miedo entre sesiones tenían más probabilidades de pertenecer a los que responden rápidamente que al grupo de los que no responden. Conclusiones: los resultados de este estudio abierto sugieren que la EPI puede ser efectiva en pacientes con TEPT con traumas interpersonales múltiples y después de múltiples intentos previos de tratamiento. Además, en esta población de TEPT crónico, la EPI era segura.
