RESUMO
BACKGROUND: Healthcare providers' attitudes and beliefs can influence how patients with persistent musculoskeletal pain are treated. A biopsychosocial approach is more effective than a purely biomedical approach. Ensuring healthcare professionals have appropriate pain science education (PSE) is essential for successful treatment outcomes. OBJECTIVE: To validate the Spanish version of the Knowledge and Attitudes of Pain (KNAP-SP) questionnaire among Spanish physiotherapists and students and analyze its psychometric properties. METHODS: From May to October 2022, two independent teams adapted the KNAP questionnaire from English to both European and Hispanic-Spanish. A cross-sectional validation study was conducted with 517 physiotherapists examining internal consistency (Cronbach's alpha), structural validity (exploratory factor analysis), and construct validity (hypothesis testing). Longitudinal analyses assessed test-retest reliability (intraclass correlation coefficient [ICC2,1; n = 63]) and responsiveness following a PSE intervention using Receiver Operating Characteristic (ROC) curve analysis and hypothesis testing (n = 70). RESULTS: The KNAP-SP showed strong internal consistency [overall α coefficient = 0.86; domain 1 (α = 0.82); domain 2 (α = 0.70)], explaining 32.3% of the variance. Construct validity was supported by 75% of the hypotheses. Test-retest reliability was high (ICC2,1 = 0.84). KNAP-SP's responsiveness was confirmed by ROC analysis (area under the curve [AUC] = 0.87 [95% CI: 0.79-0.96, p-value <.01]) and accepting 75% of prior hypotheses. The minimal clinically important change was 6.96 points. No floor or ceiling effects were detected. CONCLUSIONS: The KNAP-SP, with robust psychometric properties and successful adaptation and validation, is a valuable tool for assessing pain knowledge and attitudes among Spanish-speaking physiotherapists.
RESUMO
BACKGROUND AND OBJECTIVE: The development, evaluation and implementation of digital self-management interventions for chronic pain have increased exponentially. While intervention outcomes appear promising to improve well-being and functioning in target populations, it is unclear how the development and evaluation processes were structured and how implementation was planned and executed. The aim of this systematic review is to provide a comprehensive overview of implementation frameworks used to guide and evaluate scientific innovation in chronic pain. DATABASES AND DATA TREATMENT: Four bibliography databases (Medline, Web of Science, PsycInfo, CINAHL) and two registries (PubMed Central, MedaRxiv) were systematically searched. Hits (n = 6830) and full texts (n = 351) were screened and read by two independent reviewers. Peer-reviewed articles that met the inclusion criteria were included in the narrative synthesis. RESULTS: In total, 10 studies were identified that report on seven distinct interventions. Five implementation frameworks were utilized across these studies: Behavioural Interventions using Technology (BIT); Consolidated Framework for Implementation Research (CFIR); mHealth Agile and User-Centered Research and Development Lifecycle; Medical Research Council (MRC); Reach, Effectiveness, Adoption Implementation, and Maintenance (RE-AIM). Frameworks were operationalized using qualitative and quantitative methods, evaluating the innovation on various levels (e.g., individual vs. organizational) and applying a variety of study designs (e.g., single-arm or large trials). CONCLUSIONS: By utilizing implementation frameworks, access to evidence-based chronic pain care may be increased. Although the evidence on the utility of implementation frameworks to guide and evaluate digital self-management interventions is still limited, the body of literature is increasing. Future studies are urged to operationalize, communicate and discuss the innovation process, to promote transparency and replicability. SIGNIFICANCE: The use of implementation frameworks to guide and evaluate digital self-management interventions for chronic pain is a recent development in the field. Several promising examples exist and are presented in this review. Currently, the evidence is still limited, and prospective studies need to transparently operationalize, communicate and discuss their efforts. By utilizing an implementation framework, promising interventions can be made available to end-users, closing the research-to-clinical practice gap and increasing access to evidence-based care to people with chronic pain.

BACKGROUND: The negative consequences of prescription opioid misuse and opioid use disorder make it relevant to identify factors associated with this problem in individuals with chronic pain. This cross-sectional study aimed at identifying subgroups of people with chronic pain based on their psychological profiles, prescription opioid misuse, craving, and withdrawal. METHODS: The sample comprised 185 individuals with chronic pain. We performed hierarchical cluster analysis on impulsivity, anxiety sensitivity, pain acceptance, pain intensity, opioid misuse, craving, and withdrawal. RESULTS: The four-cluster solution was the optimal one. Misuse, craving, and anxiety sensitivity were higher among people in the Severe-problems cluster than among people in the other three clusters. Withdrawal was the highest in the High-withdrawal cluster. Impulsivity was higher among people in the Severe-problems and High-withdrawal clusters than those in the Moderate-problems and Mild-problems clusters. Pain acceptance was higher among people in the Mild-problems cluster than among people in the other three clusters. Anxiety sensitivity and misuse were higher among people in the Moderate-problems cluster than among people in the Mild-problems cluster. CONCLUSIONS: These results support that impulsivity, anxiety sensitivity, and pain acceptance are useful constructs to identify subgroups of people with chronic pain according to their level of prescription opioid misuse, craving, and withdrawal. The results of this study may help in selecting the early intervention most suitable for each of the identified profiles. SIGNIFICANCE: The psychological profile of individuals with chronic pain, prescription opioid misuse, craving, and withdrawal is characterized by fearing anxiety-related symptoms due to the catastrophic interpretation of such symptoms and reacting impulsively to negative moods. In contrast, participants with high pain acceptance had less prescription opioid misuse, craving, and withdrawal. The profiles identified in this study could help clinicians select targets for intervention among profiles with similar needs and facilitate early interventions to prevent opioid misuse onset or aggravation.

This work analyzes the perception of military specialists in Physical Education on how physical preparation is implemented and could be optimized in the Armed Forces. It is a quantitative, descriptive study (N = 227) having created an ad hoc questionnaire to collect these perceptions. The results indicate that the facilitators believe that: i. The current physical preparation and its evaluation bear little relation to the possible operational contexts; ii. Health and military instruction are perceived as the main training objectives; iii. The traditional training methodology does not seem to be the most suitable to achieve the operational objectives of the Units; iv. The most relevant physical qualities are swimming skill, strength, and endurance; v. The training contents during the mesocycle are still based mainly on running and calisthenics, performed at a moderate intensity; vi. Specific preparation before, during and after Operations should be increased. (AU)

PURPOSE: Team management strategies for complex colorectal polyps are recommended by professional guidelines. Multi-disciplinary meetings are used across the UK with limited information regarding their impact. The aim of this multi-centre observational study was to assess procedures and outcomes of patients managed using these approaches. METHOD: This was a retrospective, observational study of patients managed by six UK sites. Information was collected regarding procedures and outcomes including length of stay, adverse events, readmissions and cancers. RESULTS: Two thousand one hundred ninety-two complex polyps in 2109 patients were analysed with increasing referrals annually. Most presented symptomatically and the mean polyp size was 32.1 mm. Primary interventions included endoscopic therapy (75.6%), conservative management (8.3%), colonic resection (8.1%), trans-anal surgery (6.8%) or combined procedures (1.1%). The number of primary colonic resections decreased over the study period without a reciprocal increase in secondary procedures or recurrence. Secondary procedures were required in 7.8%. The median length of stay for endoscopic procedures was 0 days with 77.5% completed as day cases. Median length of stay was 5 days for colonic resections. Overall adverse event and 30-day readmission rates were 9.0% and 3.3% respectively. Malignancy was identified in 8.8%. Benign polyp recurrence occurred in 13.1% with a median follow up of 30.4 months. Screening detected lesions were more likely to undergo bowel resection. Colonic resection was associated with longer stays, higher adverse events and more cancers on final histology. CONCLUSION: Multi-disciplinary team management of complex polyps is safe and effective. Standardisation of organisation and quality monitoring is needed to continue positive effects on outcomes and services.

The interphase between tendon and bone consists of a highly specialised tissue called enthesis. Typically, the enthesis is described as a succession of four different zones: tendon, non-mineralised fibrocartilage, mineralised fibrocartilage and bone. However, the microstructure of the entheses, cellular composition and mechanical properties vary depending on their anatomical location. The present study aimed to characterise three of the most relevant sites of enthesis injury in a rat model: the patellar tendon, the Achilles tendon and the supraspinatus enthesis, in terms of biomechanics, histology and genetic expression. The patellar enthesis presented the highest ultimate load and lowest stiffness of the three, while the supraspinatus was the weakest and stiffest. The histological characterisation revealed key differences at the insertion site for each enthesis. The patellar enthesis showed a large cartilaginous area at the tendon-to-bone interphase whilst this interphase was smaller in the supraspinatus entheses samples. Furthermore, the Achilles tendon enthesis displayed a more abrupt transition from tendon to bone. Additionally, each enthesis exhibited a particular and distinct pattern of expression of tenogenic, chondrogenic and osteogenic markers. This study provided valuable insights for a better understanding of the three entheses at relevant anatomical sites. Moreover, the larger cross-sectional area of the patellar enthesis, the strong mechanical properties and the easier surgical access to this location led to the conclusion that the patellar tendon enthesis site could be most suitable for the development of a preclinical model for general enthesis regeneration studies in rats.

Antecedentes: los trastornos gastrointestinales (TGI) son comorbilidades comunes en los pacientes con trastornos del espectro autista (TEA); los tratamientos con dietas libres de gluten y caseína (LGLC) o suplementos de prebióticos/probióticos podrían reducir la severidad de los TGI. Objetivo: integrar y discutir la evidencia sobre la efectividad de las terapias con dietas LGLC y suplementos de prebióticos/probióticos sobre los TGI en pacientes con TEA. Metodología: se utilizaron las guías para la publicación de revisiones sistemáticas y metaanálisis (PRISMA). Se analizaron las características de los participantes, las intervenciones dietéticas, la administración de suplementos de prebióticos/prebióticos, los efectos de las intervenciones sobre los TGI, el riesgo de sesgo de los estudios y la seguridad de los tratamientos. Resultados: se analizaron quince investigaciones; la prevalencia de los TGI entre los pacientes con TEA fue alta (58 %; rango, 27-83 %). En más del 20 % de los pacientes intervenidos con dietas LGLC o suplementos disminuyó la severidad de los TGI (principalmente estreñimiento, diarrea y dolor abdominal). Se reportaron aumentos en los conteos de bacterias benéficas y una disminución de la proporción de bacterias patógenas tras el uso de los suplementos. Sin embargo, todas estas investigaciones presentaron sesgos metodológicos importantes. Conclusiones: aunque se han encontrado reducciones en la frecuencia y severidad de algunos TGI, la efectividad de estos tratamientos aún no se ha comprobado. Dadas las diferencias metodológicas de las investigaciones, se justifica el diseño de estudios rigurosos para evaluar los efectos terapéuticos de estos tratamientos sobre la salud gastrointestinal en pacientes con TEA (AU)
Background: gastrointestinal disorders (GIDs) are common comorbidities in patients with autism spectrum disorders (ASD); treatments with gluten- and casein-free (LGLC) diets or prebiotic/probiotic supplements may reduce the severity of GIDs. Objective: to integrate and discuss the evidence on the effectiveness of LGLC diet therapies and prebiotic/probiotic supplements on GIDs in patients with ASD. Methodology: the guidelines for the publication of systematic reviews and meta-analyses (PRISMA) were used. Participant characteristics, dietary interventions, prebiotic/prebiotic supplementation, effects of interventions on GIDs, risk of bias, and safety of treatments were analyzed. Results: fifteen investigations were analyzed; the prevalence of GIDs among patients with ASD was high (58 %; range, 27-83 %). In more than 20 % of the patients managed with LGLC diets or supplements GID severity decreased (mainly constipation, diarrhea, and abdominal pain). Increases in the counts of beneficial bacteria and a decrease in the proportion of pathogenic bacteria were reported after supplement use. However, all these investigations had significant methodological biases. Conclusions: although reductions in the frequency and severity of some GIDs have been found, the effectiveness of these treatments has not been proven yet. Given the methodological differences in the investigations, the design of rigorous studies to evaluate the therapeutic effects of these treatments on gastrointestinal health in patients with ASD is warranted (AU)

The color of plant leaves can be assessed qualitatively by color charts or after processing of digital images. This pilot study employed a novel pocket-sized sensor to obtain the color of plant leaves. In order to assess its performance, a color-dependent parameter (SPAD index) was used as the dependent variable, since there is a strong correlation between SPAD index and greenness of plant leaves. A total of 1,872 fresh and intact leaves from 13 crops were analyzed using a SPAD-502 meter and scanned using the Nix™ Pro color sensor. The color was assessed via RGB and CIELab systems. The full dataset was divided into calibration (70% of data) and validation (30% of data). For each crop and color pattern, multiple linear regression (MLR) analysis and multivariate modeling [least absolute shrinkage and selection operator (LASSO), and elastic net (ENET) regression] were employed and compared. The obtained MLR equations and multivariate models were then tested using the validation dataset based on r, R2, root mean squared error (RMSE), and mean absolute error (MAE). In both RGB and CIELab color systems, the Nix™ Pro color sensor was able to differentiate crops, and the SPAD indices were successfully predicted, mainly for mango, quinoa, peach, pear, and rice crops. Validation results indicated that ENET performed best in most crops (e.g., coffee, corn, mango, pear, rice, and soy) and very close to MLR in bean, grape, peach, and quinoa. The correlation between SPAD and greenness is crop-dependent. Overall, the Nix™ Pro color sensor was a fast, sensible and an easy way to obtain leaf color directly in the field, constituting a reliable alternative to digital camera imagery and associated image processing.

The aim of this study was to manufacture magnesium-fortified Chihuahua cheese and to evaluate the effect of magnesium fortification on quality parameters. Addition of magnesium chloride to milk during pasteurization (5.44, 10.80, 16.40, 22.00, and 25.20 g of MgCl2·6H2O/L of milk) resulted in cheese with increased magnesium content, proportional to the amount of magnesium added (up to 2,957.13 mg of Mg/kg of cheese). As magnesium content increased, coagulation time and moisture content also increased, whereas calcium content decreased. Higher levels of magnesium fortification (16.40 g of MgCl2·6H2O/L of milk or more) induced the development of bitter-acid flavors and softer texture. Addition of 10.80 g of MgCl2·6H2O/L to milk resulted in Chihuahua cheese that meets regulatory standards and possesses physicochemical and sensory characteristics similar to those of nonfortified Chihuahua cheese. Under this milk fortification level, the manufactured cheese is able to provide 148.4 mg of magnesium per day (35% of the recommended daily intake of magnesium for adult males and 46% for adult females) assuming 3 portions (28 g each) are consumed.

Previous studies indicate that the activity of hypothalamic POMC neurons can be regulated by glucose via intracellular mechanisms, but its regulation by lactate is poorly understood. In addition to its energetic role, lactate acts as a signaling molecule. In this study, we evaluated the function and location of the lactate receptor, hydroxycarboxylic acid receptor 1 (HCAR1). We used a conditional genetic approach to label POMC neurons and evaluated their sensitivity to lactate using patch-clamp recordings. L-Lactate and 3-chloro-5-hydroxybenzoic acid (3Cl-HBA), HCAR1 specific agonist depolarized POMC neurons and the increase in excitability was abolished by pertussis toxin (PTX), indicating the involvement of Gαi/o-protein-coupled receptors. In addition, the depolarization of a subset of POMC neurons was sensitive to α-cyano-4-hydroxycinnamate (4-CIN), a lactate transporter blocker, suggesting that the depolarization induced by L-lactate can also occur by direct intracellular action. Surprisingly, HCAR1 was not detected in POMC neurons, but instead localized in astrocytes. These results suggest a new lactate-mediated mechanism for astrocyte-neuron intercellular communication.

Abstract The Toltén river is located in the 137 years old Araucania region, Chile (38° S), and is characterized by low alterations through human interference due agriculture and towns in its surrounding basin, the presence of native fishes and salmonids, and by its lake effluent regime originated from Villarrica lake. The aim of the present study was to make a review of ecological role of the benthic inland water macroinvertebrates as preys for native fishes of the River Toltén, in order to understand their importance in the ecosystem of the river. The literature revealed that the main prey for native fishes are Chironomidae larvae, nevertheless there are not specific reports for Tolten river. The exposed results are similar with similar native species for Patagonia, and these native species would have prey for introduced salmonids, or these species would have prey competition with introduced salmonids in according to the literature descriptions for Argentinean and Chilean Patagonia.

Introduction: Current evidence suggests non-pharmacological management as the first line of treatment for people with fibromyalgia. However, reviews with an emphasis on clinical applicability are rare. Objective: To describe evidence-based clinical recommendations for the rehabilitation of people with Fibromyalgia. Methods: Medline, Web of Science and, Scielo databases were electronically searched for each of the sections of this review. Different search strategies were carried out with the combination of MESH terms and keywords. Primary and secondary studies published in English or Spanish in peer-reviewed journals were included. Results: Health professionals must know contemporary theoretical aspects of chronic pain and fibromyalgia to avoid overdiagnosis, stigmatization, and persistence of symptoms by professional instruction. A multidimensional clinical assessment with objective and subjective evaluations in a positive context with an emphasis on the construction of a therapeutic alliance facilitates shared decision-making and the selection of successful intervention strategies. Education is the starting point of rehabilitation and its combination with psychological therapy, facilitates active coping and therapeutic adherence. Physical activity and regular exercise are the most evidenced non-pharmacological interventions for improving pain, disability, quality of life, physical function, fatigue, muscle strength, stiffness, sleep, and mood in people with fibromyalgia.Conclusion:Non-pharmacological approaches are promising in the management of fibromyalgia. This review provides practical recommendations for clinical implementation by interdisciplinary health teams.(AU)

The effects of the consumption of high-fat diets (HFD) have been studied to unravel the molecular pathways they are altering in order to understand the link between increased caloric intake, metabolic diseases, and the risk of cognitive dysfunction. The saturated fatty acid, palmitic acid (PA), is the main component of HFD and it has been found increased in the circulation of obese and diabetic people. In the central nervous system, PA has been associated with inflammatory responses in astrocytes, but the effects on neurons exposed to it have not been largely investigated. Given that PA affects a variety of metabolic pathways, we aimed to analyze the transcriptomic profile activated by this fatty acid to shed light on the mechanisms of neuronal dysfunction. In the current study, we profiled the transcriptome response after PA exposition at non-toxic doses in primary hippocampal neurons. Gene ontology and Reactome pathway analysis revealed a pattern of gene expression which is associated with inflammatory pathways, and importantly, with the activation of lipid metabolism that is considered not very active in neurons. Validation by quantitative RT-PCR (qRT-PCR) of Hmgcs2, Angptl4, Ugt8, and Rnf145 support the results obtained by RNAseq. Overall, these findings suggest that neurons are able to respond to saturated fatty acids changing the expression pattern of genes associated with inflammatory response and lipid utilization that may be involved in the neuronal damage associated with metabolic diseases.

BACKGROUND: Many Spanish hospitals converted scheduled in-person visits to telephone visits during the COVID-19 lockdown. There is scarce information about the performance of those visits. AIM: To compare telephone visits during the COVID-19 lockdown period with previous in-person visits. DESIGN: Retrospective descriptive study. METHODS: Telephone visits from 15 March to 31 May 2020 were compared with in-person visits during the same period in 2019. MAIN MEASURES: The proportions of both groups were compared in term of failure to contact patient, requested diagnostic tests/referrals, discharges, admissions and emergency visits within 30-60 days. A sample of patients, and all participating physicians completed surveys. Z-score test was used (statistical significance P<0.05). RESULTS: A total of 5602 telephone visits were conducted. In comparison to in-person visits, telephone visits showed higher rates of visit compliance (95.9% vs. 85.2%, P<0.001) and discharges (22.12% vs. 11.82%; P<0.001), and lower number of ancillary tests and referrals. During the 30- and 60-day periods following the telephone visit, a reduction of 52% and 47% in the combined number of emergency department visits and hospital admissions was observed compared to in-person visits (P<0.01). Of the 120 patients surveyed, 95% were satisfied/very satisfied with the telephone visits. Of the 26 physicians, 84.6% considered telephone visits were useful to prioritize patients. CONCLUSIONS: During health emergencies, previously scheduled outpatient in-person visits can be converted to telephone visits, reducing absenteeism, increasing the rate of discharges and reducing ancillary tests and referrals without increasing the rate of hospital admissions or emergency department visits.

INTRODUCCIÓN: La donación y el trasplante de órganos y tejidos representan el avance terapéutico más importante de los tiempos actuales. La córnea es, por mucho, uno de los tejidos más trasplantados a nivel mundial gracias a los privilegios inmunológicos encontrados en este tejido, además de los avances en microcirugía, la existencia de bancos corneales, la preservación de córneas y la aplicación de terapia contra el rechazo. Sin embargo, muchos pacientes con trasplantes corneales exitosos (con córneas claras) experimentan mala visión en el periodo postoperatorio por astigmatismo irregular u otras complicaciones. OBJETIVO: Evaluar la calidad de vida relacionada con la visión en pacientes sometidos a queratoplastia penetrante. MATERIAL Y MÉTODOS: Estudio transversal-analítico que incluye pacientes con antecedente de queratoplastia penetrante, mayores de 18 años y al menos 6 meses de posquirúrgico. Los pacientes respondieron el Visual Function Questionnaire25 (VFQ-25) de la función visual, instrumento validado para su uso en español, y en el que a mayor puntación mejor calidad de vida. RESULTADOS: Se incluyeron 30 pacientes (20 hombres y 10 mujeres), con una media de edad de 61,2 ± 18,7 años. El tiempo de evolución posterior al trasplante fue de 17,7 ± 4 meses. La puntuación total en la calidad de vida fue de 74,9 ± 21,9, con significación estadística en la agudeza visual (p < 0,001) y en la presencia de enfermedades sistémicas (p = 0,018). No hubo significación estadística en el motivo de trasplante (p= 0,098) ni en la presencia de enfermedades oculares (p = 0,119). CONCLUSIÓN: Los resultados sugieren que la agudeza visual, así como la presencia de enfermedades sistémicas, tienen un impacto significativo en la calidad de vida
INTRODUCTION: Organ and tissue donation and transplantation represent the most important therapeutic advance of current times. The cornea is, by far, one of the most transplanted tissues worldwide due to the immune privilege of this tissue, as well as the advances in microsurgery, existence of cornea banks, preservation of corneas, and use of anti-rejection therapy. However, many patients with successful corneal transplants (with clear corneas) experience poor vision in the post-operative period due to irregular astigmatism, or other complications. OBJECTIVE: To evaluate the quality of life related to vision in patients undergoing penetrating keratoplasty. MATERIAL AND METHODS: A cross-analytical study including patients with a history of penetrating keratoplasty, over 18years of age, and at least 6months after surgery. The patients answered the Visual Function Questionnaire25 (VFQ-25) of visual function, a tool validated for use in Spanish, in which the higher the score, the better the quality of life. RESULTS: Thirty patients (20 men and 10 women), with a mean age of 61.2 ± 18.7 years, were included. The time of evolution after the transplant was 17.7 ± 4 months. The total quality of life score was 74.9 ± 21.9, with significance in visual acuity (P < .001), and the presence of systemic comorbidities (P = .018). There was no significance between the transplant reason (P = .098) or ocular comorbidities (P = .119). CONCLUSION: The results suggest that visual acuity, as well as the presence of systemic comorbidities, has a significant impact on quality of life

The lack of proper gastrointestinal models assessing the inter-strain virulence variability of foodborne pathogens and the effect of the vehicle (food matrix) affects the risk estimation. This research aimed to propose a dynamic and integrated in vitro/ex vivo gastrointestinal model to evaluate the probability and severity of infection of foodborne pathogens at different matrices. An everted gut sac was used to determine the adhesion and invasion of Salmonella enterica and tissue damage. S. Typhimurium ATCC 14028 was used as a representative bacterium, and two matrices (water and cheese) were used as vehicles. No differences (p > 0.05) in the probability of infection (Pinf) were found for intra-experimental repeatability. However, the Pinf of cheese-vehiculated S. Typhimurium was different compared to water- vehiculated S. Typhimurium, 7.2-fold higher. The histological analysis revealed Salmonella-induced tissue damage, compared with the control (p < 0.05). In silico proposed interactions between two major Salmonella outer membrane proteins (OmpA and Rck) and digested peptides from cheese casein showed high binding affinity and stability, suggesting a potential protective function from the food matrix. The results showed that the everted gut sac model is suitable to evaluate the inter-strain virulence variability, considering both physiological conditions and the effect of the food matrix.
