Family functioning in students of health sciences in four Latin American countries: a study of the structure and factorial invariance of the FACES III scale. A cross-sectional study.

BACKGROUND: Psychometric studies of the FACES III scale in Spanish-speaking countries show a lack of agreement on the factorial structure of the scale. In addition, most of the studies have only performed exploratory analyses of its factorial structure. OBJECTIVE: The objective of the present study was to confirm the structure and factorial invariance of the FACES III scale in nursing and obstetric students from Chile, Colombia, Peru, and Mexico. METHODS: A total of 3303 students from the four countries participated in this study (Colombia = 1559, Chile = 1224, Peru = 215, Mexico = 305). RESULTS: The results of the study showed that the Bi-factor model presents the best-fit indexes to the data from Colombia, Chile, and Mexico, but not from Peru. In addition, it was found that this model showed evidence of being strictly invariant among the three countries in the sequence of the invariance models proposed: metric invariance (ΔRMSEA = .000), scalar (ΔRMSEA = .008), and strict (ΔRMSEA = .008). The bi-factor model also showed adequate reliability indexes in the three countries. CONCLUSION: It is concluded that the FACES III scale shows adequate psychometric performance under a bi-factor model in nursing and obstetric students from Colombia, Chile, and Mexico. The lack of fit of the model in Peru could be associated with the small sample size.

Evaluation of the psychometric properties of the family adaptability and cohesion scale (FACES III) through item response theory models in students from Chile and Colombia.

BACKGROUND: A psychometric study of the Family Adaptability and Cohesion Scale (FACES III) has been conducted in Spanish-speaking countries from the perspective of the classical test theory. However, this approach has limitations that affect the psychometric understanding of this scale. OBJECTIVE: Accordingly, this study used the item response theory to investigate the psychometric performance of the items. Furthermore, it evaluated the differential performance of the items for Colombia and Chile. METHOD: For this purpose, 518 health science students from both countries participated. Confirmatory Factor Analysis was used. RESULTS: The study results revealed that the cohesion and adaptability items presented adequate discrimination and difficulty indices. In addition, items 5, 8, 13, 17, and 19 of cohesion indicated differential functioning between students from both countries, with Chilean students exhibiting a greater discriminatory power. Further, the Colombian group exhibited a greater discriminatory power for item 18 of adaptability. CONCLUSIONS: The study concluded that the items of FACES III indicated adequate psychometric performance in terms of their discriminative capacity and difficulty in Chile and Colombia.

La empatía de los enfermeros con los pacientes en los hospitales públicos / Working nurses' empathy with patients in public hospitals / A empatia dos enfermeiros com os pacientes em hospitais públicos

Objetivo: determinar los niveles de empatía en profesionales de enfermería de un hospital de alta complejidad, relacionar la edad con la empatía (y cada una de sus dimensiones), y establecer si existen diferencias entre estos niveles según el tipo de jornada laboral. Método: diseño comparativo, correlacional y transversal. La muestra utilizada (n=271) constituyó el 40,9% del total de profesionales de enfermería. Se estudiaron las propiedades psicométricas de la Escala de Empatía de Jefferson para Profesionales de la Salud. Se calcularon estadísticos descriptivos: media y desviación estándar. La asociación entre empatía y edad se estimó mediante ecuaciones de regresión y significancia estadística de los coeficientes de regresión, luego de evaluar el tipo de curva mediante análisis de varianza. Resultados: se identificó el modelo subyacente de las tres dimensiones de la empatía. Los valores de los estadísticos descriptivos observados fueron relativamente bajos en empatía y sus dimensiones. Los niveles de empatía no se asociaron con el rango de edad. No se encontraron diferencias en la empatía entre los tipos de horarios de trabajo. Se encontró variabilidad en las dimensiones: "cuidado compasivo" y "ponerse en los zapatos del paciente". Conclusión: estos resultados muestran que los niveles de empatía observados pueden implicar un desempeño deficiente en el cuidado empático de los pacientes.

Objective: to determine the levels of empathy in professional nurses of a high-complexity hospital, to relate age to empathy (and each one of its dimensions), and to establish if there are differences between these levels according to the type of working schedules. Method: comparative, correlational and cross-sectional design. The sample used (n=271) constituted 40.9% of the total number of nursing professionals. Psychometric properties of the Jefferson Scale of Empathy for Health Professionals were studied. Descriptive statistics were calculated: mean and standard deviation. The association between empathy and age was estimated using regression equations and statistical significance of the regression coefficients, after evaluating the type of curve using variance analysis. Results: the underlying model of three dimensions of empathy was identified. The values of the descriptive statistics observed were relatively low in empathy and its dimensions. Empathy levels were not associated with the age range. No differences in empathy were found between the types of work schedules. Variability was found in the dimensions: "compassionate care" and "Walking on the patient's shoes". Conclusion: these results show that the levels of empathy observed may imply a deficient performance in empathetic care for patients.

Apobec-Mediated Retroviral Hypermutation In Vivo is Dependent on Mouse Strain.

Replication of the complex retrovirus mouse mammary tumor virus (MMTV) is antagonized by murine Apobec3 (mA3), a member of the Apobec family of cytidine deaminases. We have shown that MMTV-encoded Rem protein inhibits proviral mutagenesis by the Apobec enzyme, activation-induced cytidine deaminase (AID) during viral replication in BALB/c mice. To further study the role of Rem in vivo , we have infected C57BL/6 (B6) mice with a superantigen-independent lymphomagenic strain of MMTV (TBLV-WT) or a mutant strain (TBLV-SD) that is defective in Rem and its cleavage product Rem-CT. Unlike MMTV, TBLV induced T-cell tumors in µMT mice, indicating that mature B cells, which express the highest AID levels, are not required for TBLV replication. Compared to BALB/c, B6 mice were more susceptible to TBLV infection and tumorigenesis. The lack of Rem expression accelerated B6 tumorigenesis at limiting doses compared to TBLV-WT in either wild-type B6 or AID-deficient mice. However, unlike proviruses from BALB/c mice, high-throughput sequencing indicated that proviral G-to-A or C-to-T changes did not significantly differ in the presence and absence of Rem expression. Ex vivo stimulation showed higher levels of mA3 relative to AID in B6 compared to BALB/c splenocytes, but effects of agonists differed in the two strains. RNA-Seq revealed increased transcripts related to growth factor and cytokine signaling in TBLV-SD-induced tumors relative to those from TBLV-WT, consistent with a third Rem function. Thus, Rem-mediated effects on tumorigenesis in B6 mice are independent of Apobec-mediated proviral hypermutation.

Staff perceptions towards virtual reality-motivated treadmill exercise for care home residents: a qualitative feedback study with key stakeholders and follow-up interview with technology developer.

OBJECTIVES: Health and care resources are under increasing pressure, partly due to the ageing population. Physical activity supports healthy ageing, but motivating exercise is challenging. We aimed to explore staff perceptions towards a virtual reality (VR) omnidirectional treadmill (MOTUS), aimed at increasing physical activity for older adult care home residents. DESIGN: Interactive workshops and qualitative evaluation. SETTINGS: Eight interactive workshops were held at six care homes and two university sites across Cornwall, England, from September to November 2021. PARTICIPANTS: Forty-four staff participated, including care home, supported living, clinical care and compliance managers, carers, activity coordinators, occupational therapists and physiotherapists. INTERVENTIONS: Participants tried the VR treadmill system, followed by focus groups exploring device design, potential usefulness or barriers for care home residents. Focus groups were audio-recorded, transcribed verbatim and thematically analysed. We subsequently conducted a follow-up interview with the technology developer (September 2022) to explore the feedback impact. RESULTS: The analysis produced seven key themes: anticipated benefits, acceptability, concerns of use, concerns of negative effects, suitability/unsuitability, improvements and current design. Participants were generally positive towards VR to motivate care home residents' physical activity and noted several potential benefits (increased exercise, stimulation, social interaction and rehabilitation). Despite the reported potential, staff had safety concerns for frail older residents due to their standing position. Participants suggested design improvements to enhance safety, usability and accessibility. Feedback to the designers resulted in the development of a new seated VR treadmill to address concerns about falls while maintaining motivation to exercise. The follow-up developer interview identified significant value in academia-industry collaboration. CONCLUSION: The use of VR-motivated exercise holds the potential to increase exercise, encourage reminiscence and promote meaningful activity for care home residents. Staff concerns resulted in a redesigned seated treadmill for those too frail to use the standing version. This novel study demonstrates the importance of stakeholder feedback in product design.

Conserved, yet disruption-prone, gut microbiomes in neotropical bumblebees.

IMPORTANCE: Social bees are an important model for the ecology and evolution of gut microbiomes. These bees harbor ancient, specific, and beneficial gut microbiomes and are crucial pollinators. However, most of the research has concentrated on managed honeybees and bumblebees in the temperate zone. Here we used 16S rRNA gene sequencing to characterize gut microbiomes in wild neotropical bumblebee communities from Colombia. We also analyzed drivers of microbiome structure across our data and previously published data from temperate bumblebees. Our results show that lineages of neotropical bumblebees not only retained their ancient gut bacterial symbionts during dispersal from North America but also are prone to major disruption, a shift that is strongly associated with parasite infection. Finally, we also found that microbiomes are much more strongly structured by host phylogeny than by geography, despite the very different environmental conditions and plant communities in the two regions.

(3) Low levels of empathy could imply a negative alteration of humanized attention.

Systematic profiling of subtelomeric silencing factors in budding yeast.

Subtelomeric gene silencing is the negative transcriptional regulation of genes located close to telomeres. This phenomenon occurs in a variety of eukaryotes with salient physiological implications, such as cell adherence, virulence, immune-system escape, and ageing. The process has been widely studied in the budding yeast Saccharomyces cerevisiae, where genes involved in this process have been identified mostly on a gene-by-gene basis. Here, we introduce a quantitative approach to study gene silencing, that couples the classical URA3 reporter with GFP monitoring, amenable to high-throughput flow cytometry analysis. This dual silencing reporter was integrated into several subtelomeric loci in the genome, where it showed a gradual range of silencing effects. By crossing strains with this dual reporter at the COS12 and YFR057W subtelomeric query loci with gene-deletion mutants, we carried out a large-scale forward screen for potential silencing factors. The approach was replicable and allowed accurate detection of expression changes. Results of our comprehensive screen suggest that the main players influencing subtelomeric silencing were previously known, but additional potential factors underlying chromatin conformation are involved. We validate and report the novel silencing factor LGE1, a protein with unknown molecular function required for histone H2B ubiquitination. Our strategy can be readily combined with other reporters and gene perturbation collections, making it a versatile tool to study gene silencing at a genome-wide scale.

Genomic and Evolutionary Features of Nine AHPND Positive Vibrio parahaemolyticus Strains Isolated from South American Shrimp Farms.

Vibrio parahaemolyticus is a bacterial pathogen that becomes lethal to Penaeus shrimps when acquiring the pVA1-type plasmid carrying the PirABvp genes, causing acute hepatopancreatic necrosis disease (AHPND). This disease causes significant losses across the world, with outbreaks reported in Southeast Asia, Mexico, and South America. Virulence level and mortality differences have been reported in isolates from different locations, and whether this phenomenon is caused by plasmid-related elements or genomic-related elements from the bacteria remains unclear. Here, nine genomes of South American AHPND-causing V. parahaemolyticus (VPAHPND) isolates were assembled and analyzed using a comparative genomics approach at (i) whole-genome, (ii) secretion system, and (iii) plasmid level, and then included for a phylogenomic analysis with another 86 strains. Two main results were obtained from our analyses. First, all isolates contained pVA1-type plasmids harboring the toxin coding genes, and with high similarity with the prototypical sequence of Mexican-like origin, while phylogenomic analysis showed some level of heterogeneity with discrete clusters and wide diversity compared to other available genomes. Second, although a high genomic similarity was observed, variation in virulence genes and clusters was observed, which might be relevant in the expression of the disease. Overall, our results suggest that South American pathogenic isolates are derived from various genetic lineages which appear to have acquired the plasmid through horizontal gene transfer. Furthermore, pathogenicity seems to be a multifactorial trait where the degree of virulence could be altered by the presence or variations of several virulence factors. IMPORTANCE AHPND have caused losses of over $2.6 billion to the aquaculture industry around the world due to its high mortality rate in shrimp farming. The most common etiological agent is V. parahaemolyticus strains possessing the pVA1-type plasmid carrying the PirABvp toxin. Nevertheless, complete understanding of the role of genetic elements and their impact in the virulence of this pathogen remains unclear. In this work, we analyzed nine South American AHPND-causing V. parahaemolyticus isolates at a genomic level, and assessed their evolutionary relationship with other 86 strains. We found that all our isolates were highly similar and possessed the Mexican-type plasmid, but their genomic content did not cluster with other Mexican strains, but instead were spread across all isolates. These results suggest that South American VPAHPND have different genetic backgrounds, and probably proceed from diverse geographical locations, and acquire the pVA1-type plasmid via horizontal gene transfer at different times.

Mixed-Methods Evaluation of Father Participation in an Adolescent Obesity Prevention Program With Multiple Delivery Methods.

Padres Preparados, Jóvenes Saludables was a Latino family-based obesity prevention intervention implemented from 2017 to 2020 across eight programs in-person only, in a blended format (online/in-person), and online only. The intervention aimed to enhance father parenting skills to improve adolescent diet and activity behaviors. Mothers were encouraged to attend. Factors associated with participation were explored using a mixed-methods, qualitative (focus group/individual interviews by Zoom) and quantitative (process evaluation) design. Eleven focus group and 24 individual interviews were completed after participation with 24 fathers, 27 mothers, and 40 adolescents with responses not sorted by delivery method before analysis. Binomial logistic regression models examined associations between fathers' program completion and predictor variables of delivery characteristics, father demographic characteristics, and family attendance patterns. Parents were married (96% fathers, 76% mothers), had low income, a high school education or less (68% fathers, 81% mothers), and had lived in the United States a mean of 19 years. Parents were motivated to participate to improve health, and to be involved with and improve communication with their child. Common barriers to participation were work and life priorities and programmatic factors including scheduling conflicts and technological issues. Participation was greater for fathers attending sessions in-person compared with online only (OR = 11.6). Fathers were more likely to participate if they attended sessions with family members vs. not attending with family members (OR = 7.2). To maximize participation, findings suggest involving multiple parents/caregivers and adolescents, addressing contextual and programmatic barriers, and promoting benefits of better health and relations with family members.

Family Functioning as an Explanatory Factor of Empathic Behavior in Argentine Medical Students.

Empathy is a relevant competence in the study and practice of medicine whose development could depend on the functioning style of each family. This study aims to compare the distribution of empathy levels, about functionality or dysfunction, and the three styles, which can be derived from family functioning in the families of Argentine medical students. Previously providing evidence of the validity of the family functioning measure. As well as provide evidence of the validity of the measure of family functioning. METHODS: Ex post facto design: 306 Argentine medical students who had already taken the Jefferson Scale of Empathy-Spanish Edition (JSE-S) and the abbreviated Spanish Family Adaptability and Cohesion Evaluation Scale (FACES-20). A gender-weighted linear regression analysis was made, establishing an ANOVA and multiple comparisons via DMS to determine the effect of functional and dysfunctional families' balanced, intermediate and extreme functioning styles concerning empathy. RESULTS: Students who presented dysfunction in familial cohesion and adaptability showed measures of empathy greater than those classified as functional. Differences of cohesion were statistically significant in compassionate care, perspective taking and general empathy. These components were significantly higher in students from families classified as extreme than balanced ones. Students classified within families with either extreme or dysfunctional styles showed greater levels of empathy than more adaptive and functional ones, except in the 'walking in patient's shoes' component where differences were not observed. CONCLUSIONS: Individual resilience as an intervening variable in the presence of empathy is discussed. IMPLICATIONS: The study of empathy, its associated variables, and the conditions of its development remains a central theme in relation to students and professionals of the health sciences. To achieve an effective professional practice, it is necessary to develop human capacities such as empathy and personal resilience.

Bacteriophages playing nice: Lysogenic bacteriophage replication stable in the human gut microbiota.

Bacteriophages, viruses specific to bacteria, coexist with their bacterial hosts with limited diversity fluctuations in the guts of healthy individuals where they replicate mostly via lysogenic replication. This favors 'piggy-back-the-winner' over 'kill-the-winner' dynamics which are driven by lytic bacteriophage replication. Revisiting the deep-viral sequencing data of a healthy individual sampled over 2.4 years, we explore how these dynamics occur. Prophages found in assembled bacterial metagenomes were also found extra-cellularly, as induced phage particles (iPPs), likely derived from prophage activation. These iPPs were diverse and continually present in low abundance, relative to the highly abundant but less diverse lytic phage population. The continuous detection of low levels of iPPs suggests that spontaneous induction regularly occurs in this healthy individual, possibly allowing prophages to maintain their ability to replicate and avoiding degradation and loss from the gut microbiota.

Rational Design of Profile HMMs for Sensitive and Specific Sequence Detection with Case Studies Applied to Viruses, Bacteriophages, and Casposons.

Profile hidden Markov models (HMMs) are a powerful way of modeling biological sequence diversity and constitute a very sensitive approach to detecting divergent sequences. Here, we report the development of protocols for the rational design of profile HMMs. These methods were implemented on TABAJARA, a program that can be used to either detect all biological sequences of a group or discriminate specific groups of sequences. By calculating position-specific information scores along a multiple sequence alignment, TABAJARA automatically identifies the most informative sequence motifs and uses them to construct profile HMMs. As a proof-of-principle, we applied TABAJARA to generate profile HMMs for the detection and classification of two viral groups presenting different evolutionary rates: bacteriophages of the Microviridae family and viruses of the Flavivirus genus. We obtained conserved models for the generic detection of any Microviridae or Flavivirus sequence, and profile HMMs that can specifically discriminate Microviridae subfamilies or Flavivirus species. In another application, we constructed Cas1 endonuclease-derived profile HMMs that can discriminate CRISPRs and casposons, two evolutionarily related transposable elements. We believe that the protocols described here, and implemented on TABAJARA, constitute a generic toolbox for generating profile HMMs for the highly sensitive and specific detection of sequence classes.

3D Printed Larynx as a Novel Simulation Tool for Window Elaboration in Medialization Laryngoplasty.

OBJECTIVE: Surgical simulation training in residents has declined due to the limited exposure to cadaveric specimens. Three-dimensional (3D)-printing technology is rapidly taking an important role in different medical areas, especially in surgical specialties. It provides an alternative for resident simulation practices and for developing surgical skills before exposure to real settings. The elaboration of the thyroid window in the medialization laryngoplasty procedure requires high technical precision and experience for better outcomes. METHODS: The computer-based 3D reconstruction model was created using computed tomograph scan images from a standard larynx. The final model was created using a deposition modeling 3D printing technique with polylactic acid filament. The model was tested for surgical simulation practice in three otolaryngology residency programs in Bogotá, Colombia. RESULTS: The model had similar anatomic detail and it was considered very useful, safe, and relevant for surgical simulation. CONCLUSIONS: 3D printed models are a cost-effective alternative for resident training.

Empathy, psychometrics, cut-off points in nursing students from Latin America.

BACKGROUND: Currently, there are no cut-off points for levels of empathy, making it difficult to assess the change experienced in its development or as a result of its intervention. It is an unsolved problem. INTRODUCTION: Empathy is a cognitive-affective attribute that enables nursing staff to maintain a professional relationship that entails various benefits for the patient. Its strengthening and development during university education is desirable. Empathy studies in Latin American nursing students are based on the direct scores obtained on an empathy test, based on which the variable is described and groups are compared. Statistical comparisons are not enough to discriminate substantive changes since two statistical values can show differences without implying that the post-intervention levels may correspond to a higher category in relation to those of pre-intervention or that two compared groups are qualitatively different. The above applies to empathic behaviour and is valid for students and professionals of health. This study aimed to establish cut-off points that allow defining ordinal categories in empathy. METHODS: In this multicenter and cross-sectional study, 3712 students from 11 Latin American nursing schools participated. The Jefferson Empathy Scale (JES) was applied; the psychometric properties were confirmed by Factor Analysis Confirmatory and Invariance. RESULTS: The JSE empathy scale is a measure with adequate reliability and construct validity. Examined cut-offs determined a structure of five empathy intervals that allowed them to be classified as empathy values in very high, high, medium, low and very low. DISCUSSION: The sequence of statistical tests carried out allowed us to determine ranges of categorical values in the empathy levels of groups of students. However, the determined categories may constitute a specific characteristic of them. It is not possible to extrapolate these results to regions other than those of Latin America. CONCLUSION: The estimated rankings allow comparing levels of empathy between groups of nursing students and the real effect of empathic interventions. IMPLICATIONS FOR NURSING: To contribute with strategies to evaluate changes in the empathic skills of nursing students, resulting in a well-valued skill in health services. IMPLICATIONS FOR NURSING POLICY: The cut-off points define evaluative categories (very low, low, medium, high and very high) that allow objective classification of levels of empathy achieved after (for example) an empathic intervention. This allows assessment of substantive changes experienced by nursing students (and professionals).

Family Functioning as a Possible Factor that Modulates Empathy Levels in Dental Students

Aim: The objective of this paper is to explore whether there are differences in the levels of empathy and its dimensions between family typologies in dental students. Methodology: A quantitative and not experimental study, with a cross-sectional descriptive design, a population of dental students from the Evangelical University of El Salvador, and a convenience sample were applied. The levels of empathy and family functioning were evaluated using the Jefferson Scale of Empathy for Health Professions students and the Brief Scale of Family Functioning. The construct validity of both instruments was estimated using Confirmatory Factor Analysis. The reliability was estimated using McDonald's omega and Cronbach's alpha. Comparisons of empathy and its dimensions between family typologies were made using a two-factor analysis of variance. Results: No statistical differences were observed in empathy and its dimensions based on family typologies. It was found that women are more empathic than men. This result is not in accordance with other studies carried out in Latin America on dental and medical students evaluating empathy and family functioning with the same instruments. Conclusions: The distribution of empathy levels and their dimensions are similar among the family typologies studied. Therefore, it was not found that family functioning can influence empathy in the population studied. It is necessary to continue these studies to obtain more empirical evidence regarding the influence of family functioning on empathy.

Objetivo: El objetivo del presente trabajo es determinar la existencia de diferencias de los niveles de empatía y de sus dimensiones entre las tipologías familiares en estudiantes de odontología. Metodología: Estudio cuantitativo y no experimental, con un diseño descriptivo transversal, una población de estudiantes de odontología de la Universidad Evangélica de El Salvador y una muestra por conveniencia. Fueron evaluados los niveles de empatía y el funcionamiento familiar mediante la Escala de Empatía de Jefferson para estudiantes de profesiones de la salud y la Escala Breve de Funcionamiento Familiar. Se estimó la validez de constructo de ambos instrumentos mediante Análisis Factorial Confirmatorio y la confiabilidad mediante omega de McDonald y alfa de Cronbach. Las comparaciones de la empatía y sus dimensiones entre las tipologías familiares fueron realizadas mediante análisis de varianza bifactorial. Resultados: No se observaron diferencias estadísticas en la empatía y en sus dimensiones en función de las tipologías familiares. Se encontró que las mujeres son más empáticas que los hombres. Este resultado no está en concordancia con otros estudios realizados en América Latina en estudiantes de odontología y medicina, evaluando la empatía y el funcionamiento familiar con los mismos instrumentos. Conclusiones: La distribución de los niveles de empatía y de sus dimensiones son semejantes entre las tipologías familiares estudiadas. Por lo tanto, no se constató que el funcionamiento familiar tenga un efecto sobre la empatía en la población estudiada. Es necesario continuar estos estudios para obtener mayor evidencia empírica respecto de la influencia del funcionamiento familiar en la empatía.

Factors Associated with Fathers' Attendance in a Latino Family Obesity Prevention Program.

Community-based programs may contribute to Latino pediatric obesity prevention; however, attendance remains low. This study aimed to identify factors associated with Latino father/male caregiver attendance in family-based adolescent obesity prevention programs conducted as part of a randomized controlled trial. The study used cross-sectional data from 137 fathers in the program, involving eight weekly sessions to improve their children's energy balance-related behaviors. Evaluation data were collected at baseline and post-intervention. Fathers in a waitlisted control group attended sessions after post-intervention data collection. Attendance patterns were identified using cluster analysis: consistently high attendance (50% of fathers), declining attendance (19%), and non-attendance (31%) clusters. Multinomial logistic regression was used to examine associations between attendance patterns and variables. Compared to consistently high attendance, fathers in the non-attendance cluster were more likely to have been assigned to the control group (odds ratio [OR] = 7.86, p < 0.001), tended to have lower household income (OR = 2.50, p = 0.098), and attended the program at a site where the program occurred weekdays (OR = 0.35, p = 0.094). Maintaining contact during waiting periods and providing sessions online or during weekends could reduce non-attendance by enhancing convenience for low-income fathers working multiple jobs.

Correlation Between the Sinew Channels with the Myofascial System, Pathology, and Treatment.

The sinew channels are a tendon and muscle network, and their description is based on the observation presented on the Huangdi Neijing Ling Shu. However, the myofascial system is an uninterrupted series of connective tissue that is comprised of layers that run in different directions. The similarities on these pathways are compared, such as a brief description on the myofascial pain syndrome and its similitude with the Impediment disorder from the Traditional Chinese Medicine (TCM). Furthermore, we discuss the treatment of these conditions from a Traditional Chinese Medicine perspective.
