Psychopathy, pain, and pain empathy: A psychophysiological study.

The present study examined whether people higher in psychopathy experienced less self-reported and psychophysiological nociceptive pressure than people lower in psychopathy. We also examined whether psychopathy affects empathy for others' pain via self-reported and psychophysiological measures. Three hundred and sixty-nine students (18-78 years; M = 26, SD = 9.34) were screened for psychopathic traits using the Youth Psychopathy Inventory (YPI). Stratified sampling was used to recruit 49 adults residing in the highest (n = 23) and lowest (n = 26) 20% of the psychopathy spectrum. Using skin conductance response (SCR) and self-report responses, participants responded to individually adjusted intensities of pneumatic pressure and others' pain images and completed self-reported psychopathy and empathy measures (Triarchic Psychopathy Measure, TriPm; Interpersonal Reactivity Index, IRI). People higher in psychopathy self-reported feeling less nociceptive pressure compared to people lower in psychopathy, yet we did not find any differences in SCR to nociceptive pressure. However, when viewing other people in pain, the high psychopathy group displayed lower SCR and lower self-reported empathy compared to those lower in psychopathy. Our results suggest psychopathic traits relate to problems empathising with others' pain, as well as the perception of nociceptive pressure. We also show support for the theory of dual harm which has been receiving increasing attention. Consequently, psychopathy interventions should focus both on recognising and empathising with the pain of others.

Investigating the Psychological Impact of Cyber-Sexual Harassment.

The impact of cyber sexual harassment (CSH) on adult women and the factors influencing this impact are largely under-researched. Communication technologies provide novel means for people to threaten, communicate, and harass others. Victims of in-person sexual harassment (ISH) can experience negative symptoms of depression, anxiety, trauma, and negative body image. The current study explored the psychological impact of CSH in adult women to determine whether CSH predicts psychological difficulties. Adult female participants (N = 136) took part in an online, cross-sectional study; 44% of participants had experienced CSH and this was associated with higher levels of depression, anxiety, trauma, and body image dissatisfaction. Younger victims, those who had been in a relationship for a shorter amount of time, those who had previously experienced of ISH, and those who had a higher number of social media followers were more likely to have experienced CSH. When controlling for demographic variables, CSH predicted anxiety, depression, trauma, and body image dissatisfaction; however, experience of ISH impacted upon body-image dissatisfaction over and above CSH. There is a need to routinely ask individuals accessing mental health services whether online interactions cause harm. Future research should examine these phenomena in more ethnically diverse samples.

Intervención fisioterapéutica en fibromialgia

Introducción: La fibromialgia afecta el movimiento corporal. Provoca dolor en puntos claves, causa molestias musculoesqueléticas y limita la actividad de las personas.

The physiotherapy treatment of fibromyalgia must have a component of aerobic physical exercise and strength to reduce fatigue, to return the muscle to its functionality and increase aerobic capacity.

Is Oral Vaccination against Escherichia coli Influenced by Zinc Oxide?

BACKGROUND: Although zinc oxide has been banned at therapeutic doses in the EU, its use is still legal in most countries with industrial pig farming. This compound has been shown to be very effective in preventing E. coli-related diseases. However, another strategy used to control this pathogen is vaccination, administered parenterally or orally. Oral vaccines contain live strains, with F4 and F18 binding factors. Since zinc oxide prevents E. coli adhesion, it is hypothesised that its presence at therapeutic doses (2500 ppm) may alter the immune response and the protection of intestinal integrity derived from the vaccination of animals. METHODS: A group of piglets were orally vaccinated at weaning and divided into two subgroups; one group was fed a feed containing 2500 ppm zinc oxide (V + ZnO) for the first 15 days post-vaccination (dpv) and the other was not (V). Faeces were sampled from the animals at 6, 8, 11, 13, and 15 dpv. Unvaccinated animals without ZnO in their feed (Neg) were sampled simultaneously and, on day 15 post-vaccination, were also compared with a group of unvaccinated animals with ZnO in their feed (ZnO). RESULTS: Differences were found in E. coli excretion, with less quantification in the V + ZnO group, and a significant increase in secretory IgA in the V group at 8 dpv, which later equalised with that of the V + ZnO group. There was also some difference in IFNα, IFNγ, IL1α, ILß, and TNFα gene expression when comparing both vaccinated groups (p < 0.05). However, there was no difference in gene expression for the tight junction (TJ) proteins responsible for intestinal integrity. CONCLUSIONS: Although some differences in the excretion of the vaccine strain were found when comparing both vaccinated groups, there are no remarkable differences in immune stimulation or soluble IgA production when comparing animals orally vaccinated against E. coli in combination with the presence or absence of ZnO in their feed. We can conclude that the immune response produced is very similar in both groups.

Soft Tissue Grafting Procedures before Restorations in the Esthetic Zone: A Minimally Invasive Interdisciplinary Case Report.

An esthetically pleasing smile is a valuable aspect of physical appearance and plays a significant role in social interaction. Achieving the perfect balance between extraoral and intraoral tissues is essential for a harmonious and attractive smile. However, certain intraoral deficiencies, such as non-carious cervical lesions and gingival recession, can severely compromise the overall aesthetics, particularly in the anterior zone. Addressing such conditions requires careful planning and meticulous execution of both surgical and restorative procedures. This interdisciplinary clinical report presents a complex case of a patient with esthetic complaints related to asymmetric anterior gingival architecture and severely discolored and eroded maxillary anterior teeth. The patient was treated using a combination of minimally invasive ceramic veneers and plastic mucogingival surgery, resulting in a successful outcome. The report emphasizes the potential of this approach in achieving optimal esthetic results in challenging cases, highlighting the importance of an interdisciplinary team approach in achieving a harmonious balance between dental and soft tissue aesthetics.

Assessing Combinations of B(C6 F5 )3 and N2 -Derived Molybdenum Nitrido Complexes for Heterolytic Bond Activation.

Two different dinitrogen-derived molybdenum nitrido complexes varying by their geometry, ligand spheres and oxidations states were shown to engage their N ligand in dative bonding with the strong Lewis acid B(C6 F5 )3 . The stable adducts were assessed for frustrated Lewis pair-type heterolytic E-H bond splitting of hydrosilanes (E=Si) and HB(C6 F5 )2 . Whereas Si-H bond activation was achieved, HB(C6 F5 )2 was shown to substitute B(C6 F5 )3 in a quantitative or equilibrated fashion, depending on the nature of the nitrido complex. No B-H bond splitting was observed. Thermodynamics of these reactions, computed by DFT, are in agreement with the experimental outcomes.

Callous-Unemotional Traits are Associated With Child-to-Parent Aggression.

This study examined the relations between callous-unemotional traits and perpetration of aggression toward parents in two separate studies, while also considering motivation for aggression and parenting styles experienced among young people. Study 1 involved 60 parents of children aged between 11 and 17 years old. The online study found high callous-unemotional traits, as reported by parents, to be associated with aggression toward both parents. Both types of motivation (proactive and reactive, as reported by parents) were associated with aggression toward parents. Study 2 involved 42 youths from an alternative education sample (between 11 and 16 years old). Youths with higher self-reported callous-unemotional traits reported more aggression toward both parents. Both studies, which had different reporters and different samples, showed youths with higher callous-unemotional traits were more aggressive toward their parents. In discussing the results, we note the importance of including callous-unemotional traits in future research on parent-directed aggression and in studies on domestic violence more broadly.

Arthroscopic repair of partial-thickness articular surface rotator cuff tears: single-row transtendon technique versus double-row suture bridge (transosseous equivalent) fixation: results from a prospective randomized study.

BACKGROUND: The purpose of this prospective study was to compare the clinical and structural findings following the arthroscopic repair of partial-thickness (exceeding 50%) articular-sided rotator cuff tears using either a single-row or a double-row suture bridge fixation. MATERIALS AND METHODS: Fifty patients were included in this study. The patients were randomly placed into two groups: 25 underwent the single-row (Group I) and 25 a double-row suture bridge fixation (Group II). The clinical outcomes were assessed using ASES and Constant shoulder scores, both preoperatively and at the end of follow-up. The pain level was evaluated using the visual analogue scale (VAS), preoperatively, at 6 months and at the end of follow-up. All patients underwent preoperative MRI to identify the rotator cuff tear, and postoperatively at 12 months to evaluate tendon integrity. RESULTS: The average follow-up was 32.5 months. The mean ASES scores increased from 35.9 to 96.7 in Group I and from 35.3 to 93.4 in Group II; the mean Constant shoulder scores increased from 55.6 to 97.8 in Group I and from 57.5 to 97.3 in Group II. There were no significant differences between the two groups. The average preoperative pain level decreased from 7.4 to 3 at 6 months and to 0.4 at the end of the Group I; and from 7.6 to 3 at 6 months and 0.8 in Group II. There was no significant difference between the two groups. At 12 months, the MRI assessments showed two retears in Group I (8%) and one retear in Group II (4%). CONCLUSION: Arthroscopic repair of partial-thickness articular rotator cuff tears that exceed 50% of tendon thickness with a single-row transtendon repair or double-row suture bridge provides functional improvement and pain relief regardless of the repair technique used. There were no differences in clinical results between both techniques. LEVEL OF EVIDENCE: Level II; prospective comparative study.

La artroplastia invertida de hombro ante defectos óseos glenoideos / Reverse shoulder arthroplasty due to glenoid bone defects

Objetivo. La artroplastia invertida se está convirtiendo en una herramienta útil para afecciones muy variadas en el hombro. Un defecto óseo importante de la glena puede afectar a la fijación del componente glenoideo. El propósito de nuestro estudio es evaluar a medio plazo los resultados de la artroplastia invertida de hombro asociados a una glenoplastia. Material y métodos. Se realizó un estudio retrospectivo de 5 pacientes de nuestro hospital con defectos glenoideos de distinta etiología que fueron tratados mediante artroplastia invertida de hombro asociada a glenoplastia. Resultados. El seguimiento mínimo de estos pacientes fue de un año (con una media de 30,4 meses). Todos los injertos estaban radiológicamente integrados, sin observarse signos de resorción o necrosis. A los 12 meses el test de Constant era de 66,75 de media y el EVA medio era de 1. Discusión. La glenoplastia es una intervención de alta demanda técnica que consigue restaurar el remanente óseo en pacientes con defectos estructurales, permitiendo así implantar una artroplastia invertida. De esa forma podemos mejorar la función y la clínica en pacientes con diversas afecciones glenohumerales, proporcionándoles una solución (AU)

Main Ingredients for Success in L2 Academic Writing: Outlining, Drafting and Proofreading.

Spanish undergraduates of English Studies are required to submit their essays in academic English, a genre which most of them are not acquainted with. This paper aims to explore the extralinguistic side of second language (L2) academic writing, more specifically, the combination of metalinguistic items (e.g. transition and frame markers, among others) with students' writing strategies when composing an academic text in L2 English. The research sample conveys a group of 200 Spanish undergraduates of English Studies; they are in their fourth year, so they are expected to be proficient in English academic writing but their written production quality varies considerably. Results are analysed following a mixed methodology by which metalinguistic items are statistically measured, and then contrasted with semi-structured interview results; SPSS and NVivo provide quantitative and qualitative outcomes, respectively. The analyses reveal that undergraduate students who produce complex sentences and more coherent texts employ a wider range of writing strategies both prior and while writing, being able to (un)consciously structure and design their texts more successfully. These high-scoring students make more proficient use of complex transition markers for coherence and frame markers for textual cohesion; their commonly used (pre-)writing strategies are drafting, outlining, and proofreading.

The ALK translocation in advanced non-small-cell lung carcinomas: preapproval testing experience at a single cancer centre.

AIMS: To study the ALK translocation in patients with advanced non-small-cell lung carcinomas (NSCLCs) seen at a European cancer centre, and its association with EGFR mutations, KRAS mutations and MET amplification. METHODS AND RESULTS: The study included samples from 86 patients diagnosed with advanced NSCLC. ALK fluorescence in-situ hybridization (FISH) was performed using the ALK break-apart probe set (Vysis). ALK FISH-positive cases were defined as those with more than 15% break-apart signals or isolated red signals in 50 cells. EGFR and KRAS mutations were determined by direct sequencing. All ALK-positive cases were analysed retrospectively for MET amplification using a FISH assay, and for ALK mutations by sequencing. We found nine (10.5%) ALK-positive cases, all in adenocarcinomas and the majority in female patients (88.9%). Signet ring cells were observed in four (44.4%) of the nine patients. None of the ALK translocated cases showed MET amplifications or EGFR, KRAS and ALK mutations. CONCLUSIONS: The prevalence of ALK translocation in an unselected population of European patients with advanced NSCLCs was 10%. This alteration was mutually exclusive with EGFR and KRAS mutations, as well as with MET amplification. If multiplexing is considered at the preanalytical phase, lung biopsy specimens are sufficient for performing several predictive assays.

Violence exposure mediates the relation between callous-unemotional traits and offending patterns in adolescents.

The link between callous-unemotional (CU) traits in youth and delinquent, aggressive and violent behavior is well-replicated in the literature. However, the mediating effects of violence exposure on this relationship are unclear. The current study addresses this important gap in the literature with a sample of 88 detained, primarily ethnic minority adolescent boys (M age = 15.57; SD = 1.28). Results indicate that exposure to violence fully mediated the relationship between CU traits and violent delinquency, and this pattern of mediation was accounted for by exposure to witnessed violence, but not direct violent victimization. Secondly, exposure to violence, both direct and witnessed forms, also mediated the relationship between CU traits and drug delinquency. These findings suggest that (a) the well-established link between CU traits and violence may be attributed to high rates of witnessed violence among this subpopulation, and (b) specific types of violence exposure may be important for predicting the offending patterns of youth high on CU traits. Theoretical and practical implications are discussed.

Psychometric properties of the Spence Children's Anxiety Scale (SCAS) in Cypriot children and adolescents.

The Spence Children's Anxiety Scale (SCAS) is a 38-item self-report questionnaire which measures symptoms of DSM-IV anxiety disorders in children and adolescents. This study examined the psychometric properties of the Greek translation of SCAS in a large community sample of children and adolescents (N = 1,072), aged 12-17 years, in the non-occupied territory of Cyprus. A subsample of these participants was retested 8 weeks after the initial assessment. The SCAS demonstrated high internal consistency (alpha = .92) and test-retest reliability (r = .88). The SCAS total scores correlated significantly with the anxious/depressed subscale of the Youth Self-Report, the Columbia Impairment Scale, and with the emotional subscale of the Strength and Difficulties Questionnaire. Confirmatory factor analyses revealed the same six-factor structure as the original SCAS. The SCAS proved to be a reliable and valid measure of anxiety symptoms in the Cypriot context.

Assessing the forms and functions of aggression using self-report: factor structure and invariance of the Peer Conflict Scale in youths.

This study examined the structure of a self-report measure of the forms and functions of aggression in 855 adolescents (582 boys, 266 girls) aged 12 to 19 years recruited from high school, detained, and residential settings. The Peer Conflict Scale (PCS) is a 40-item measure that was developed to improve upon existing measures and provide an efficient, reliable, and valid assessment of four dimensions of aggression (i.e., reactive overt, reactive relational, proactive overt, and proactive relational) in youths. Confirmatory factor analyses showed that a 4-factor model represented a satisfactory solution for the data. The factor structure fit well for both boys and girls and across high school, detained, and residential samples. Internal consistency estimates were good for the 4 factors, and they showed expected associations with externalizing variables (i.e., arrest history, callous-unemotional traits, and delinquency). Reactive and proactive subtypes showed unique associations consistent with previous literature. Implications for the use of the PCS to assess aggression and inform intervention decisions in diverse samples of youths are discussed.

Parental monitoring and youth behavior problems: moderation by callous-unemotional traits over time.

Prior research suggests that parents' monitoring behaviors are related to the conduct problems of children but not to the conduct problems of children with callous-unemotional traits. However, these studies have been cross-sectional. The present short-term longitudinal study investigates the bidirectional influences of parental monitoring and youth problem behaviors, while also examining the potential moderating influence of callous-unemotional traits. We assessed adolescents (Mean age = 14.5 years; SD = 1.8) and parents at two time points. Youths reported their callous-unemotional traits and delinquency, while parents reported their child's conduct problems, and their parenting behaviors to track and control their child's activities. We found support for a child-driven change in parents' monitoring behaviors over time. Specifically, children with high callous-unemotional traits had parents who reduced their monitoring behaviors over time, and their different types of monitoring behaviors were less synchronous over time. In addition, parents of youths with high callous-unemotional traits showed a trend toward not being stable in their surveillance efforts over time. Moreover, greater behavioral control for youths high on callous-unemotional traits did not lead to parents' greater knowledge about their youths. In fact, having less knowledge was related to decreases in parental control, when youths were high on callous-unemotional traits. The present study supports the importance of personality in shaping how parents actively monitor their children.

Sexually coercive tactics used by university students: a clear role for primary psychopathy.

Current research suggests that people with psychopathic traits engage in sexual coercion as an alternative mating strategy. Research overlooks the relation between psychopathic traits and coercive behavior in male and female samples that engage in dating quite frequently. Male and female university students reported on their current relationship styles and their use of minor and severe sexually coercive tactics. Results indicate that primary psychopathy (using the Levenson's SRPS), but not secondary psychopathy, predicts the use of all measures of sexual coercion for both females and males, although males were more likely to exploit an intoxicated partner than females. Additionally, females with high levels of primary psychopathy were more likely to use physical forms of coercion. The findings show that the primary psychopathy features (callousness, charm, and selfishness) predict a shortterm mating strategy that focuses on gaining sex through minor forms of coercion and manipulation.

Disinhibited behaviors in young children: relations with impulsivity and autonomic psychophysiology.

Cardiac activity has long been considered as a psychophysiological marker of adaptive psychological adjustment. Irregularities in autonomic nervous system activity have long been implicated in both externalizing and disinhibitory behaviors. The present study used a battery of assessments in children ages 4.5-5.5 years to examine the relation among disinhibitory measures. Additionally, cardiovascular activity and reactivity was examined. Mothers rated impulsivity and internalizing/externalizing behaviors. Reward-dominance and passive-avoidance response inhibition (i.e., via errors of commission) tasks were included. Results showed that behaviorally uninhibited children began with an attenuated sympathetic response (i.e., lengthened pre-ejection period) to an interview with a novel experimenter, while inhibited children began with a high level of sympathetic activity. Further, behavioral impulsivity was related to low sympathetic activity at rest. Consistent with theories of disinhibition, externalizing behaviors and measures of behavioral impulsivity were related to a reward-dominant response style. Findings are discussed with regard to motivational theories of behavior.
