A novel manual therapy approach for managing acute interscapular pain following median sternotomy for open cardiac surgery: A clinical comparative analysis.

INTRODUCTION: Acute interscapular pain is a frequent postoperative complication observed in patients who have undergone median sternotomy. This study aimed to assess a novel approach to manual therapy utilizing the Regional Interdependence (RI) concept for managing interscapular pain in post-sternotomy patients. MATERIALS AND METHODS: In an observational study, a cohort of 60 consecutively admitted patients undergoing median sternotomy was enrolled. Data collection involved standardized clinical evaluations conducted at specific time points: prior to manual treatment (T0), following five manual treatments (T5), and at post-treatment days 10 (T10) and 30 (T30). The Experimental Group (EG) received manual treatment based on the RI concept, performed in a seated position to accommodate individual clinical conditions and surgical wound considerations. The Control Group (CG) received simulated treatment involving identical exercises to the EG but lacking the physiological or biomechanical stimulation. RESULTS: Among the initial 60 patients, 36 met the inclusion criteria, while 24 were excluded due to one or more exclusion criteria. Treatment outcomes revealed a statistically significant improvement in the EG compared to the CG, not only in terms of pain reduction but also in functional recovery and consequent disability reduction. DISCUSSION: The RI concept emerges as a potentially valuable therapeutic approach for addressing interscapular dysfunction, particularly in highly complex post-sternotomy patients. This study highlights the clinical relevance of the RI concept in the management of interscapular pain and highlights its potential utility in improving patient outcomes in the challenging context of sternotomy surgery.

Rehabilitation Interventions for Improving Balance in Parkinson's Disease: A Narrative Review.

INTRODUCTION: Postural instability is one of the latest clinical manifestations of Parkinson disease. Because of the limited therapeutic effect of pharmacological therapies, a favorable consideration has now become toward rehabilitation interventions. Thus, this study aimed to synthesize literature evidence to summarize the effects of rehabilitation interventions for improving balance in Parkinson disease. MATERIALS AND METHODS: We conducted a narrative review of randomized-controlled clinical trials comparing the effects of interventions, control interventions, and no interventions on balance-related outcomes. A comprehensive search using the MEDLINE database was conducted from January 2000 to September 2021. This review included the following causes of balance-related impairments: inability to control body weight in the base of support, impaired attention and focus on balance, postural deformities, proprioceptive deficiency, sensory-motor integration, and coordination disorders, including visual and auditory-motor coordination. RESULTS: Twenty randomized-controlled clinical trials were included in the review. Various balance-related outcomes were included. The included studies focused on the effectiveness of different rehabilitation interventions, including physical therapy, virtual reality and telerehabilitation, treadmill training, hydrotherapy, action observation training, balance and cues training interventions, and cognitive rehabilitation. CONCLUSIONS: The results suggest that most of the included rehabilitation interventions have promising therapeutic effects in improving balance in Parkinson disease.

Age, empathy, familiarity, domestication and call features enhance human perception of animal emotion expressions.

Vocalizations constitute an effective way to communicate both emotional arousal (bodily activation) and valence (negative/positive). There is strong evidence suggesting that the convergence of vocal expression of emotional arousal among animal species occurs, hence enabling cross-species perception of arousal, but it is not clear if the same is true for emotional valence. Here, we conducted a large online survey to test the ability of humans to perceive emotions in the contact calls of several wild and domestic ungulates produced in situations of known emotional arousal (previously validated using either heart rate or locomotion) and valence (validated based on the context of production and behavioural indicators of emotions). Participants (1024 respondents from 48 countries) were able to rate above chance levels the arousal level of vocalizations of three of the six ungulate species and the valence of four of them. Percentages of correct ratings did not differ a lot across species for arousal (49-59%), while they showed much more variation for valence (33-68%). Interestingly, several factors such as age, empathy, familiarity and specific features of the calls enhanced these scores. These findings suggest the existence of a shared emotional system across mammalian species, which is much more pronounced for arousal than valence.

The Effect of Manual Therapy Plus Exercise in Patients with Lateral Ankle Sprains: A Critically Appraised Topic with a Meta-Analysis.

A high percentage of patients with lateral ankle sprains report poor outcomes and persistent neuromuscular impairment leading to chronic ankle instability and re-injury. Several interventions have been proposed and investigated, but the evidence on manual therapy combined with therapeutic exercise for pain reduction and functional improvement is still uncertain. The purpose was to study the effectiveness of adding manual therapy to therapeutic exercise in patients with lateral ankle sprains through a critically appraised topic. The literature search was performed in PubMed, PEDro, EMBASE and CINAHL databases, and only randomized clinical trials were included according to following criteria: (1) subjects with acute episodes of lateral ankle sprains, (2) administered manual therapy plus therapeutic exercise, (3) comparisons with therapeutic exercise alone and (4) reported outcomes for pain and function. Three randomized clinical trials (for a total of 180 patients) were included in the research. Meta-analyses revealed that manual therapy plus exercise was more effective than only exercises in improving dorsal (MD = 8.79, 95% CI: 6.81, 10.77) and plantar flexion (MD = 8.85, 95% CI 7.07, 10.63), lower limb function (MD = 1.20, 95% CI 0.63, 1.77) and pain (MD = -1.23; 95% IC -1.73, -0.72). Manual therapy can be used with therapeutic exercise to improve clinical outcome in patients with lateral ankle sprains.

Classification of pig calls produced from birth to slaughter according to their emotional valence and context of production.

Vocal expression of emotions has been observed across species and could provide a non-invasive and reliable means to assess animal emotions. We investigated if pig vocal indicators of emotions revealed in previous studies are valid across call types and contexts, and could potentially be used to develop an automated emotion monitoring tool. We performed an analysis of an extensive and unique dataset of low (LF) and high frequency (HF) calls emitted by pigs across numerous commercial contexts from birth to slaughter (7414 calls from 411 pigs). Our results revealed that the valence attributed to the contexts of production (positive versus negative) affected all investigated parameters in both LF and HF. Similarly, the context category affected all parameters. We then tested two different automated methods for call classification; a neural network revealed much higher classification accuracy compared to a permuted discriminant function analysis (pDFA), both for the valence (neural network: 91.5%; pDFA analysis weighted average across LF and HF (cross-classified): 61.7% with a chance level at 50.5%) and context (neural network: 81.5%; pDFA analysis weighted average across LF and HF (cross-classified): 19.4% with a chance level at 14.3%). These results suggest that an automated recognition system can be developed to monitor pig welfare on-farm.

How does semantic pain and words condition pain perception? A short communication.

INTRODUCTION AND SCOPE: Language is one of the main tools with whom people describe their pain. The semantic value of words plays a fundamental role in the pain perception, intended as a complex process of modulation and processing in the brain. The priming effect is a cognitive process in which a certain stimulus can influence subsequent stimuli. It is therefore plausible that this effect plays a key role in the modulation and perception of pain. This study aimed to investigate the potential relationship between the semantic aspects of language, the priming effect, and the perception of pain. METHODS AND RESULTS: A narrative review of the literature was conducted. Sixteen studies were included and categorized in four groups based on the effect of the verbal suggestion on the experimental acute pain and chronic pain and on the effect of pain-related words in free pain and post-surgical subjects. CONCLUSIONS: There may be a link between language and pain, both at the behavioral and neural level. The processing of semantic information associated with pain influences the pain perception.

Acute Traumatic and Ischemic Spinal Cord Injuries Have a Comparable Course of Recovery.

Background. The relative rarity of ischemic compared with traumatic spinal cord injury (SCI) has limited a comparison of the outcomes of these conditions. Objective. To investigate the neurological and functional recovery of ischemic compared with traumatic acute SCI. Methods. Data were derived from the European Multicenter Study Spinal Cord Injury database. Patients with ischemic (iSCI) or traumatic SCI (tSCI), aged 18 years or older were evaluated at different time points from incidence: at about 1 month, 3 months, and 6 months. The neurological status was assessed at each time point by the International Standards for Neurological Classification of Spinal Cord Injury and the functional status by the Spinal Cord Independence Measure. Walking ability was evaluated by Walking Index for Spinal Cord Injury, 10-Meter Walk Test, and 6-Minute Walk Test. Because of the imbalances of the 2 groups in respect to size and lesion severity, a matching procedure according to age, neurological level, and severity of injury was performed. Outcomes evaluation was performed by means of a 2-way repeated-measures ANOVA. Results. The matching procedure resulted in 191 pairs. Both groups significantly improved from about 15 days after the lesion to 6 months. No differences were found in the course of neurological and functional recovery of iSCI compared with tSCI. Conclusions. This analysis from a representative cohort of participants revealed that from 15 days following the cord damage onward, the outcomes after iSCI and tSCI are comparable. This finding supports the potential enrolment of patients with acute iSCI into clinical trials from that point in time after the event and an evaluation up to 6 months afterward.

The Overlooked Outcome Measure for Spinal Cord Injury: Use of Assistive Devices.

Although several outcome measures are used to assess various areas of interest regarding spinal cord injuries (SCIs), little is known about the frequency of their use, and the ways in which they transform shared knowledge into implemented practices. Herein, 800 professionals from the International Spinal Cord Society, especially trained for caring in patients with SCI, were invited to respond to an Internet survey collecting information on the use of standardized measures in daily clinical practices. We asked both clinicians and researchers with different areas of interest about their use of functional outcome measures, and, in particular, which scales they habitually use to assess various aspects of clinical practice and rehabilitation. We selected a set of rating scales, which were validated for measuring SCIs (http://www.scireproject.com/outcome-measures). The results show that the areas of interest assessed by most of the participants were neurological status, upper limb, lower limb gait, pain, spasticity, self-care, and daily living. The most widely used rating scales were the spinal cord independence measure, the functional independence measure and the International Standards for Neurological Classification of Spinal Cord Injury. Instead, the majority of respondents did not evaluate the use of assistive technology. Despite the availability of several outcome scales, the practice of evaluating SCIs with standardized measures for assistive technologies and wheelchair mobility is still not widespread, even though it is a high priority in the rehabilitation of SCI patients. The results emphasize the need for a more thorough knowledge and use of outcome scales, thus improving the quality of assistive device evaluation.

Looking on the Bright Side of Livestock Emotions-the Potential of Their Transmission to Promote Positive Welfare.

Emotions can be defined as an individual's affective reaction to an external and/or internal event that, in turn, generates a simultaneous cascade of behavioral, physiological, and cognitive changes. Those changes that can be perceived by conspecifics have the potential to also affect other's emotional states, a process labeled as "emotional contagion." Especially in the case of gregarious species, such as livestock, emotional contagion can have an impact on the whole group by, for instance, improving group coordination and strengthening social bonds. We noticed that the current trend of research on emotions in livestock, i.e., investigating affective states as a tool to assess and improve animal welfare, appears to be unbalanced. A majority of studies focuses on the individual rather than the social component of emotions. In this paper, we highlight current limitations in the latter line of research and suggest a stronger emphasis on the mechanisms of how emotions in livestock are transmitted and shared, which could serve as a promising tool to synergistically enhance the welfare of all individuals within a group.

Prediction Model for the Presence of Complications at Admission to Rehabilitation After Traumatic Spinal Cord Injury.

Background: Complications frequently occur in patients with spinal cord injury (SCI) during acute care or rehabilitation and have an impact on rehabilitation outcomes. Purpose: The aim of this study was to determine the occurrence and risk factors for complications in recently injured SCI patients. Methods: Two hundred fifty patients with traumatic injuries with and without complications were counted for the following dichotomous parameters: gender (male/female), associated lesions (presence/absence), surgery (yes/no), American Spinal Injury Association Impairment Scale (AIS) grade (A/other categories), lesion level (lumbar/other levels), and lesion-to-admission time (less than/longer than 1 month). The odds ratio (OR) and 95% confidence interval were computed for all the parameters that influenced the presence of complications at admission. These factors have been included in a binary logistic regression analysis (forward stepwise). Results: Complications at admission were observed in 104 patients (41.6%), especially for males, lesion-to-admission time longer than 1 month, presence of associated lesions, AIS grade A, and motor completeness, whereas lumbar lesions were associated with a reduced presence of complications at admission. In the regression analysis, 4 factors entered into the model: motor completeness, lesion-to-admission time, associated lesions, and gender. The final model explained 74% of the variance of data. Conclusions: Despite advances in the acute management of patients with SCI, the study unveiled a high percentage of patients with complications at admission to rehabilitation. The risk factors identified in the study allow determination of the population of subjects who are at higher risk of developing complications and need special management.

What do spinal cord injury patients think of their improvement? A study of the minimal clinically important difference of the Spinal Cord Independence Measure III.

BACKGROUND: The Spinal Cord Independence Measure (SCIM III) is a scale of independence in the activities of daily life, specifically designed for spinal cord injury subjects. AIM: The aim of this study was to calculate the minimal clinically important difference (MCID) of the SCIM III according to distribution and anchor based approach. DESIGN: Prospective study. SETTING: Four Spinal Cord Units in Italy. POPULATION: Patients with acute/subacute spinal cord injury/lesion. METHODS: The scores of the total SCIM and of the four subscale was recorded at admission and discharge. Clinical significance was calculated according to anchor based methodology using a global rating of change questionnaire. The accuracy of MCID values in predicting a judgment of small improvement by the patients has been assessed by means of the area under the receiving operating curves (aROC). RESULTS: Total SCIM MCID values varied from 12 for patients with complete tetraplegia to 45.3 for those with incomplete thoracic lesions. The MCID of self-care varied from 3.3 to 8.5 and from 10 to 18 for respiration and sphincter management, depending on the level and severity of the lesion. With regard to mobility (room and toilet), the MCID varied from 1 to 3 and from 2.5 to 7.26 for mobility (indoors and outdoors). The aROC was between good and excellent for all these values. CONCLUSIONS: The results provide benchmarks for clinicians and researchers to interpret whether patients' change score on the SCIM III can be interpreted as true or clinically meaningful and to make clinical judgments about the patients' progress. CLINICAL REHABILITATION IMPACT: Our data could be useful for both clinicians and researchers. At the beginning of rehabilitation clinicians may have an idea of the minimal improvement of the patient (based on his neurological status) that could have an impact on patient's life. At the end of rehabilitation process, it is possible to control if the patient achieved an improvement that is true and significant. Researchers could also use these criteria to evaluate the clinical significance of an intervention by calculating the number of subjects in the treatment and control groups (or in two different treatment groups) who achieved a change calculated as the natural recovery plus the MCID.

Outcomes Following Ischemic Myelopathies and Traumatic Spinal Injury.

Background: As the general population ages, the rising prevalence of vascular lesions of the spinal cord will become significant. Purpose: The aim of this study was to compare the neurological and functional outcomes of patients with ischemic spinal cord injury (ISCI) and traumatic spinal cord injury (TSCI). Methods: We conducted a retrospective study in a spinal cord unit of 2 rehabilitation hospitals. We studied 168 patients with a TSCI and 72 with an ISCI. At admission and discharge, patients were evaluated by American Spinal Injury Association Impairment Scale (AIS) standards and Spinal Cord Independence Measure (SCIM). Length of stay, occurrence of complications, and discharge dispositions were also recorded. Linear and logistic regression models were used to analyze the effects of the etiology of the lesion, AIS level at admission, and level of the lesion. Results: Patients with an ISCI were older and experienced fewer cervical lesions and fewer complete lesions than patients with TSCI. By linear and logistic regression, etiology was a predictor (together with lesion features) of functional (SCIM improvement and SCIM at discharge) outcome, with traumatic patients having better outcome than ischemic ones. Age, AIS level, and lesion level were the chief predictors of length of stay, occurrence of complications, and discharge dispositions. Conclusions: A diagnosis of ischemia and trauma could be a determinant of functional recovery in SCI patients.

Assessing and treating pain associated with stroke, multiple sclerosis, cerebral palsy, spinal cord injury and spasticity. Evidence and recommendations from the Italian Consensus Conference on Pain in Neurorehabilitation.

Pain is a common and disabling symptom in patients with stroke, multiple sclerosis (MS), cerebral palsy (CP), spinal cord injury (SCI) and other conditions associated with spasticity, but data on its prevalence, and natural history, as well as guidelines on its assessment and treatment in the field of neurorehabilitation, are largely lacking. The Italian Consensus Conference on Pain in Neurorehabilitation (ICCPN) searched and evaluated current evidence on the frequency, evolution, predictors, assessment, and pharmacological and non-pharmacological treatment of pain in patients with stroke, MS, CP, SCI and other conditions associated with spasticity. Patients with stroke, MS, CP, and SCI may suffer from pain related to spasticity, as well as nociceptive and neuropathic pain (NP), whose prevalence, natural history, impact on functional outcome, and predictors are only partially known. Diagnosis and assessment of the different types of pain in these patients is important, because their treatment may differ. Botulinum neurotoxin is the first choice treatment for spasticity, while some antidepressant and antiepileptic drugs may be effective on NP, but pharmacological treatment varies according to the underlying disease. In most cases, a single therapy is not sufficient to treat pain, and a multidisciplinary approach, which include pharmacological and non-pharmacological treatments is needed. Further studies, and in particular randomized controlled trials, are needed on these topics.

Who is going to walk? A review of the factors influencing walking recovery after spinal cord injury.

The recovery of walking function is considered of extreme relevance both by patients and physicians. Consequently, in the recent years, recovery of locomotion become a major objective of new pharmacological and rehabilitative interventions. In the last decade, several pharmacological treatment and rehabilitative approaches have been initiated to enhance locomotion capacity of SCI patients. Basic science advances in regeneration of the central nervous system hold promise of further neurological and functional recovery to be studied in clinical trials. Therefore, a precise knowledge of the natural course of walking recovery after SCI and of the factors affecting the prognosis for recovery has become mandatory. In the present work we reviewed the prognostic factors for walking recovery, with particular attention paid to the clinical ones (neurological examination at admission, age, etiology gender, time course of recovery). The prognostic value of some instrumental examinations has also been reviewed. Based on these factors we suggest that a reliable prognosis for walking recovery is possible. Instrumental examinations, in particular evoked potentials could be useful to improve the prognosis.

Genetic polymorphisms of interleukin 20 (IL-20) in patients with ulcerative colitis.

Interleukin (IL)-20 belongs to the IL-10 family and is a potent immunomodulatory cytokine with implications for pathogenesis in the inflammatory bowel disease (IBD). The interleukin 20 gene is located within a 200kb region of q31-32 locus of chromosome 1. No previous studies have reported this novel association between ulcerative colitis (UC) and IL-20 polymorphisms. In the present work, we evaluated the role of IL-20 gene polymorphisms as susceptibility markers for UC. Three polymorphisms of IL-20 gene (rs2981573, rs2232360, rs1518108) were genotyped by 5' exonuclease TaqMan genotyping assays on an ABI Prism 7900 HT Fast Real-Time PCR system in a group of 198 Mexican Mestizo patients with UC and 698 ethnically matched healthy unrelated individuals with no family history of UC. We found significant decreased frequencies of two IL-20 genotypes: GG (rs2981573) [10.6% vs. 17.6%, p=0.017, OR=0.55, 95% CI: 0.33-0.93] and GG (rs2232360) [10.6% vs. 17.6%, p=0.017, OR=0.55, 95% CI: 0.33-0.93] in UC patients as compared to healthy controls. No significant differences of gene frequencies were found between UC patients and healthy controls in the rs1518108 polymorphism. In the subgroup analysis, no differences were found between the IL-20 genotypes and the clinical characteristics of UC. The results suggest that the GG genotypes of the IL-20 polymorphisms (rs2981573 and rs2232360) might have an important role in the development of UC in the Mexican population.

Mother goats do not forget their kids' calls.

Parent-offspring recognition is crucial for offspring survival. At long distances, this recognition is mainly based on vocalizations. Because of maturation-related changes to the structure of vocalizations, parents have to learn successive call versions produced by their offspring throughout ontogeny in order to maintain recognition. However, because of the difficulties involved in following the same individuals over years, it is not clear how long this vocal memory persists. Here, we investigated long-term vocal recognition in goats. We tested responses of mothers to their kids' calls 7-13 months after weaning. We then compared mothers' responses to calls of their previous kids with their responses to the same calls at five weeks postpartum. Subjects tended to respond more to their own kids at five weeks postpartum than 11-17 months later, but displayed stronger responses to their previous kids than to familiar kids from other females. Acoustic analyses showed that it is unlikely that mothers were responding to their previous kids simply because they confounded them with the new kids they were currently nursing. Therefore, our results provide evidence for strong, long-term vocal memory capacity in goats. The persistence of offspring vocal recognition beyond weaning could have important roles in kin social relationships and inbreeding avoidance.

Measuring social problem solving using the Spanish version for Hispanics of the Social Problem Solving Inventory-Revised.

This study investigated the internal consistency, factor structure, and concurrent validity of the Social Problem Solving Inventory-Spanish Version for Hispanics (SPSI-R-Hispanic), a translation of the Social Problem Solving Inventory-Revised (SPSI-R; D'Zurilla, Nezu & Maydeu-Olivares, 2002), in a North American sample of 325 Spanish speaking Hispanics. The scales of the SPSI-R-Hispanic demonstrated good internal consistency reliability. The hypothesized factor model of the SPSI-R provided a good fit to the data. SPSI-R-Hispanic scores demonstrated concurrent validity in a multiple regression analysis, explaining 32% of incremental variability in psychological well-being scores. Gender differences were replicated, where men had higher positive problem orientation and rational problem solving scores and women had higher negative problem orientation scores.

Effect of acetaldehyde on behavioral and neurochemical changes induced by MK-801 in rats.

Alterations in motor activity related to dopamine changes in some brain regions have been described as consequences of the modifications produced by systemic administration of MK-801 (a noncompetitive NMDA receptor antagonist) in rats. Acetaldehyde (ACH), the main metabolite of ethanol, has been implicated in different alterations in the central nervous system after ethanol ingestion. ACH might exert some control on dopaminergic transmission through the formation of other compounds with dopamine, which eventually may modify dopamine content and its metabolism. In order to evaluate such a hypothesis, we used Wistar rats in the present study to evaluate the effect of ACH on locomotor alterations and dopamine metabolism changes induced by MK-801. Our results show that the MK-801-treated group had a significant increase in locomotor activity. In contrast, we did not find significant differences in locomotion tests after ACH administration. However, the group to which both drugs were administered showed a significant decrease in locomotor activity compared with those given MK-801 alone. Neurochemical analysis showed an increase in dopamine content in the striatum and frontal cortex after MK-801 administration, however; the increase was reversed by giving 200 mg/kg of ACH. These results indicate that ACH can produce an antagonic-like effect on locomotor alterations and dopamine content changes induced by MK-801, thus modulating the MK-801-induced hyperlocomotion by interfering with dopamine metabolism.
