Creative versus repetitive dance therapies to reduce the impact of fibromyalgia and pain: A systematic review and meta-analysis

Background and purposePhysical exercise is one of the most effective interventions to reduce fibromyalgia symptoms. Previous studies have reported benefits of dance-based intervention on the fibromyalgia impact, health-related quality of life and pain, regardless the interventions were based on creative- or repetitive dance. This study aimed to compare the effectiveness of creative and repetitive dance interventions.MethodsPRISMA guidelines were followed in this systematic review. The Cochrane Library, PubMed, Trip, Google Scholar, Web of Science (WOS), Embase and Scopus databases were selected to identify potential articles. Studies were included if they met the following inclusion criteria: to be a clinical trial or a randomized controlled trial, include people with fibromyalgia, have a comparison group and evaluate the impact of the disease, pain or quality of life. Fifteen articles fulfilled the inclusion criteria. The methodological quality of the studies was assessed using the Cochrane Collaboration's tool.ResultsDance-based interventions significantly reduced fibromyalgia impact (standardized mean difference = −0.69), pain (standardized mean difference = −0.70 and increased quality of life (standardized mean difference = 0.43) of people with fibromyalgia. The effectiveness of dance interventions is increased when a creative component is added, since it can lead to higher improvements in pain, impact of the disease and improving quality of life.ConclusionDance-based interventions are significantly effective in reducing the impact of fibromyalgia, pain as well as increasing health-related quality of life. Subgroup analyses suggest that creative dance-based interventions could be more effective than repetitive dance-based interventions to reduce pain and fibromyalgia impact. However, results must be taken with caution due to the large heterogeneity and the small number of articles.     

Feasibility,acceptability and effects of dance therapy in stroke patients: A systematic review

IntroductionStroke is the leading cause of non-traumatic disability in adults, with balance and gait disturbances representing the main limitations of body functions. Dance therapy (DT) has shown positive effects in older adults and in patients with neurological pathologies. This systematic review aims to examine the feasibility, acceptability and effects of DT in stroke rehabilitation, specifically on functional gains of gait and balance.MethodsA systematic search was carried out for articles published in the MEDLINE, PEDro, Web of Science, Scopus and CINHAL in February 2021 and updated in April 2021. Results: Eight studies were included (2 clinical cases, 5 case series and 1 randomized controlled trial), 7 of them in patients with chronic stroke and only 1 in subacute stroke phase. The most widely used dance modality was tango and ballet, with sessions ranging from 30 to 110 min. DT seems to show positive effects on post-stroke body functions and activities such as gait and balance. Reported dropout rates are inconsistent, no adverse effects were reported, and participant satisfaction was high.ConclusionGiven the heterogeneity and uneven quality of the included studies, strong conclusions cannot be put forward on the effectiveness of DT in post-stroke body function and activities. Nevertheless, DT seems to be safe and acceptable therapy for patients, and no adverse effects have been reported. More studies with a high level of evidence and feasibility are needed to determine the patient profile, the characteristics of the intervention, the participation rate and the role of the rehabilitation professional most likely to generate optimal benefit.     

Pediatric intestinal transplantation

Advancements in donor management, organ preservation and operative techniques, as well as immunosuppressive therapies, have provided children with intestinal failure and its complications a chance not only for enteral autonomy but also long-term survival through intestinal transplantation (ITx). First described in the 1960’s, experience has grown in managing these complex patients both pre- and post-transplant. The goals of this review are to provide a brief history of intestinal transplantation and intestinal rehabilitation in pediatric patients, followed by focused discussions of the indications for ITx, induction and maintenance immunosuppression therapies, common post-operative complications, and outcomes/quality of life post-transplant.     

The most immature infants: Is evidence-based practice possible?

IntroductionAt extremely low gestational ages, preterm infants are markedly physiologically immature, thus their responses to common clinical interventions may differ from more mature preterm babies. This study was performed to describe the evidence base which is available to make care decisions for such infants.MethodsA literature search of recent large neonatal randomized controlled trials (RCTs) was performed to determine the representation of infants <25 weeks of gestation, and whether it is clear if the overall results applied to the most immature infants.ResultsAmong 30 multi-centre RCTs in neonatology from the last 5 years, many excluded the most immature infants, and those that included them rarely presented the impacts of the intervention on the most at-risk group. Over 25,000 infants of under 32 weeks gestational age (GA) were included in these trials. Eight trials presented results of the primary outcome for infants of <26 weeks GA (n = 2,152) and a further four trials for infants <25 weeks, n = 711.ConclusionThe evidence base for treatment decisions for the highest risk infants in the NICU is severely limited. RCTs in extremely preterm infants should not exclude the highest risk group, and lower limits of gestational age (or body weight) should be avoided, any infant receiving intensive care should be eligible regardless of how immature. The results among the most immature infants should be presented separately, or be easily available, in order to build a database of effective treatments among infants of 22,23, and 24 weeks GA.     

Periventricular- intraventricular hemorrhage in the premature infant- A historical perspective

The objective of this chapter is to trace the evolution of intraventricular hemorrhage in the premature infant highlighting the importance of the germinal matrix, a critical role for cerebral blood flow changes in the genesis of hemorrhage, clinical factors that increase the bleeding risk, and potential preventative strategies. In 1976, neuropathological studies demonstrated capillary rupture within the germinal matrix as the precursor of hemorrhage. In 1980, introduction of cranial ultrasound facilitated diagnosis of intraventricular hemorrhage. In 1979, loss of cerebral autoregulation in sick newborn infants was demonstrated. In the 1980’s, studies demonstrated the importance of intravascular factors in provoking hemorrhage. In 1983, the association of cerebral blood flow velocity fluctuations and subsequent hemorrhage was demonstrated. In 1994, antenatal steroids use to accelerate lung development was recommended. This was associated with an unanticipated reduction in hemorrhage. In the mid 1990’s early indomethacin administration was associated with a reduction of severe hemorrhage.     

Exercice physique, carence estrogénique, monoxyde d'azote et remodelage osseux

Summary

Objectives

The aim of this paper is to emphasize the possible relationships established between estrogens and physical exercise and concerning bone metabolism. Nitric oxide (NO) might play an important role in such relationships.

Topics

Cellular metabolism of NO, as well as NO effects upon osteoblasts and osteoclasts have been summarized. Several studies indicate that NO deficiency might be implicated in various vascular diseases observed in post-menopausal women. Other works also indicate that NO deficiency induced by cessation of ovarian activity might be responsible for osteopenia associated with this condition. Thus, decreased production of NO would be responsible both for post-menopausal osteoporosis as well as for osteopenia sometimes observed in amenorrheic athletes. Moreover osteoblastic response to mechanical stimulation might implicate estrogenic receptor(s). The role of these receptors in the regulation of NO synthesis is still unknown.     

A case of small cerebral cyst and pericentric inversion of chromosome 9 that developed schizophrenia-like psychosis

A case of schizophrenia-like psychosis (psychotic disorder not otherwise specified according to the DSM-IV criteria) with pericentric inversion on chromosome 9 [inv.(9) (p11; q13)] is reported. In this case, a minor brain anomaly, a small cyst in the left subcortex, was observed on magnetic resonance imaging of the brain. In the clinical course, prominent chronic hallucinations were observed; however, there was no evidence of the disorganization of personality, delusion, and deterioration in level of functioning that are usually seen in schizophrenia. This case and a review of the literature indicate that the pericentric region of chromosome 9 might be a potential areas of interest for the aetiology of psychiatric disorders. The phenotype-karyotype relationship of pericentric inversion on chromosome 9 and its relationship to psychosis are discussed.

Metabolism of risperidone to 9-hydroxyrisperidone by human cytochromes P450 2D6 and 3A4

Risperidone is a relatively new antipsychotic drug that has been reported to improve both the positive and the negative symptoms of schizophrenia and produces relatively few extrapyramidal side effects at low doses. Formation of 9-hydroxyrisperidone, an active metabolite, is the most important metabolic pathway of risperidone in human. In the present study, in vitro metabolism of risperidone (100 μM) was investigated using the recombinant human cytochrome P450 (CYP) enzymes CYP1A1, CYP1A2, CYP2C8, CYP2C9-arg₁₄₄, CYP2C9-cys₁₄₄, CYP2C19, CYP2D6, CYP3A4 and CYP3A5 supplemented with an NADPH-generating system. 9-Hydroxyrisperidone was determined by a new HPLC method with an Hypersil CN column and a UV detector. Of these enzymes, CYPs 2D6, 3A4 and 3A5 were found to be the ones capable of metabolising risperidone to 9-hydroxyrisperidone, with activities of 7.5, 0.4 and 0.2 pmol pmol^–1 CYP min^–1, respectively. A correlation study using a panel of human liver microsomes showed that the formation of 9-hydroxyrisperidone is highly correlated with CYP2D6 and 3A activities. Thus, both CYP2D6 and 3A4 are involved in the 9-hydroxylation of risperidone at the concentration of risperidone used in this study. This observation is confirmed by the findings that both quinidine (inhibitor of CYP2D6) and ketoconazole (inhibitor of CYP3A4) can inhibit the formation of 9-hydroxyrisperidone. Furthermore, inducers of CYP can significantly increase the formation of 9-hydroxyrisperidone in rat. The formation of 9-hydroxyrisperidone is highly correlated with testosterone 6β-hydroxylase activities, suggesting that inducible CYP3A contributes significantly to the metabolism of risperidone in rat.
