RESUMO

BACKGROUND: Treatment of low anterior resection syndrome (LARS) is challenging. Percutaneous tibial nerve stimulation (PTNS) can improve select bowel disorders. An RCT was conducted to assess the efficacy of PTNS compared with sham stimulation in patients with severe LARS. METHOD: This was a multicentre, double-blind RCT. Patients with major LARS score were allocated to receive PTNS or sham therapy (needle placement simulation without nerve stimulation). The study included 16 sessions of 30 min once a week for 12 consecutive weeks, followed by four additional sessions once a fortnight for the following 4 weeks. The primary endpoint was efficacy of PTNS defined by the LARS score 12 months after treatment. Secondary endpoints included faecal incontinence, quality of life (QoL), and sexual function. RESULTS: Between September 2016 and July 2018, 46 eligible patients were assigned randomly in a 1 : 1 ratio to PTNS or sham therapy. Baseline characteristics were similar. LARS scores were reduced in both groups, but only patients who received PTNS maintained the effect in the long term (mean(s.d.) score 36.4(3.9) at baseline versus 30.7(11.5) at 12 months; P = 0.018; effect size -5.4, 95 per cent c.i. -9.8 to -1.0), with a mean reduction of 15.7 per cent at 12-month follow-up. The faecal incontinence score was improved after 12 months in the PTNS group (mean(s.d.) score 15.4(5.2) at baseline versus 12.5(6.4) at 12 months; P = 0.018). No major changes in QoL and sexual function were observed in either group. There was no therapy-associated morbidity. Three patients discontinued the study, but none owing to study-related issues. CONCLUSION: PTNS has positive effects in some patients with major LARS, especially in those with faecal incontinence. Registration number: NCT02517853 (http://www.clinicaltrials.gov).

RESUMO

The incidence of milk leakage (ML) after dry-off (DO) and related risk factors was studied in 1,175 dairy cows from 41 commercial herds in 8 European countries: Belgium, Czech Republic, Denmark, France, Germany, Italy, the Netherlands, and Spain. Milk leakage was assessed twice for 30 s each during 3 visits at 20 to 24 h, 30 to 34 h, and 48 to 52 h after DO. Information related to dry-cow management and udder health was collected at herd and cow level, including individual somatic cell count (ISCC) from test-day controls and occurrence of clinical mastitis cases from DO until 30 d in lactation. Mixed-effect logistic regression analyses were used to identify possible risk factors for ML and to study the association between ML and new intramammary infections. Intramammary infections were defined as clinical mastitis cases during the dry period and in the first 30 d in lactation or a rise in ISCC from before to after the dry period (threshold: 200,000 cells/mL) or both. Milk leakage was observed in 24.5% of the cows between 20 and 52 h after DO, where the herd incidence varied between 0.0 and 77.8%. The reduction in number of milkings in the weeks before DO had statistically significant effect on the ML incidence. When the milking frequency was reduced from 3 times/d to 2 or maintained at twice a day, cows had 11 (95% CI = 3.43-35.46) or 9 (95% CI = 1.85-48.22) times higher odds of leaking milk, respectively, compared with cows where the milking frequency was reduced from twice to once a day. Also, the milk production 24 h before DO was associated with ML incidence. Hence, cows with a milk production between 13 and 21 L or above 21 L had 2.3 (95% CI = 1.48-3.53) and 3.1 (95% CI = 1.79-5.3) times higher odds of leaking milk, respectively, compared with cows with a milk production below 13 L. A higher ML incidence was present in the group of cows with an average ISCC in the last 3 mo before DO ≥200,000 cells/mL (odds ratio = 1.7; 95% CI = 1.13-2.41) compared with cows with an average ISCC <100,000 cells/mL. Quarters with ML tended to have 2.0 times higher odds of developing clinical mastitis compared with quarters not leaking milk. Cows with ML tended to have 1.5 times higher odds of intramammary infections (i.e., an increase of ISCC or clinical mastitis) compared with cows without ML.

RESUMO

Criollo horse populations descend from horses brought from the Iberian Peninsula over the period of colonization (15th to 17th century). They are spread throughout the Americas and have potentially undergone genetic hybridization with other breeds in the recent past. In this study, 25 autosomal microsatellites were genotyped in 50 horse breeds representing Criollo populations from 12 American countries (27 breeds), breeds from the Iberian Peninsula (19), one breed each from France and Morocco and two cosmopolitan horse breeds (Thoroughbred and Arabian). The genetic relationships among breeds identified five clusters: Celtic; Iberian; North American with Thoroughbred influence; most Colombian breeds; and nearly all other Criollo breeds. The group of "all other Criollo breeds" had the closest genetic relationship with breeds originating from the Iberian Peninsula, specifically with the Celtic group. For the whole set of Criollo breeds analysed, the estimated genetic contribution from other breeds was approximately 50%, 30% and 20% for the Celtic, Iberian and Arab-Thoroughbred groups, respectively. The spatial distribution of genetic diversity indicates that hotspots of genetic diversity are observed in populations from Colombia, Ecuador, Brazil, Paraguay and western United States, possibly indicating points of arrival and dispersion of Criollo horses in the American continent. These results indicate that Criollo breeds share a common ancestry, but that each breed has its own identity.

RESUMO

Five per cent of patients presenting with choriocarcinoma develop small bowel metastasis. Tumors of the small bowel are rare and the metastases are generally from lung and breast carcinoma or from melanoma. Clinical presentation is vague and the majority of cases are autopsy findings. The main symptoms are related to the presence of abdominal tumor or hemorrhage, or bowel obstruction or perforation. We present the cases of three patients with small bowel metastasis from choriocarcinoma. A 24-year-old woman with bowel obstruction secondary to intussusception caused by a metastatic choriocarcinoma polypoid mass and two men, one 18 years old and the other 24 years old, with a history of testicular tumor, who presented with gastrointestinal bleeding due to small bowel metastasis from choriocarcinoma, 2 and 10 months after orchiectomy, respectively. Management was endoscopic in one case and surgical in the other two. Two patients died in the early postoperative period and one patient died during the first year of follow-up. Choriocarcinoma metastases are very rare and their main clinical manifestations are hemorrhage and bowel obstruction. Management can be either medical or surgical. The majority of patients with choriocarcinoma respond to chemotherapy but prognosis is worse for those patients presenting with small bowel metastasis.

RESUMO

BACKGROUND AND PURPOSE: The modified TICI score is the benchmark for quantifying reperfusion after mechanical thrombectomy. There has been limited investigation into the reliability of this score. We aim to identify intra-rater and inter-rater reliability of the mTICI score among endovascular neurosurgeons. MATERIALS AND METHODS: Four independent endovascular neurosurgeons (raters) reviewed angiograms of 67 patients at 2 time points. κ statistics assessed inter- and intrarater reliability and compared raters'-versus-proceduralists' scores. Reliability was also assessed for occlusion location and by dichotomizing modified TICI scores (0-2a versus 2b-3). RESULTS: Interrater reliability was moderate-to-substantial, weighted κ = 0.417-0.703, overall κ = 0.374 (P < .001). The dichotomized modified TICI score had moderate-to-substantial interrater agreement, κ statistics = 0.468-0.715, overall κ = 0.582 (P < .001). Intrarater reliability was moderate-to-almost perfect, weighted κ = 0.594-0.81. The dichotomized modified TICI score had substantial-to-almost perfect reliability, κ = 0.632-0.82. Proceduralists had fair-to-moderate agreement with raters, weighted κ = 0.348-0.574, and the dichotomized modified TICI score had fair-to-moderate agreement, κ = 0.365-0.544. When proceduralists and raters disagreed, proceduralists' scores were higher in 79.6% of cases. M1 followed by ICA occlusions had the highest agreement. CONCLUSIONS: The modified TICI score is a practical metric for assessing reperfusion after mechanical thrombectomy, though not without limitations. Agreement improved when scores were dichotomized around the clinically relevant threshold of successful revascularization. Interrater reliability improved with time, suggesting that formal training of interventionalists may improve reporting reliability. Agreement of the modified TICI scale is best with M1 and ICA occlusion and becomes less reliable with more distal or posterior circulation occlusions. These findings should be considered when developing research trials.

RESUMO

In Cushing's syndrome, GH secretion is blocked with all the stimuli tested. It has been reported that the acute pharmacological reduction of free fatty acids (FFA) leads to an enhancement of GH secretion in normal subjects and in pathological conditions associated with reduced GH secretion. To understand if the elevated FFA levels of hypercortisolism may be responsible for the altered GH secretion, 14 patients with active Cushing's syndrome underwent 2 paired tests with 100 micrograms i.v. of GHRH on 2 different occasions. In one test, they were pretreated with placebo and in the other one, with acipimox 250 mg p.o. 4 h before, and 250 mg p.o. 1 h before GHRH. The basal FFA levels (799 +/- 57 mmol/L) were reduced by acipimox throughout the whole test (values under 240 +/- 28 mmol/L). In the placebo pretreated group, GHRH-induced GH secretion was severely impeded, with a mean GH peak of 1.8 +/- 0.3 micrograms/L and area under the curve of 121.3 +/- 21.6 micrograms/L-120 min. All the patients showed a GHRH-mediated GH peak under 4 micrograms/L. Acute reduction of FFA by acipimox enhanced the GHRH action, with a mean GH peak of 11.1 +/- 1.8 micrograms/L and area under the curve of 652.9 +/- 110.3 micrograms/L-120 min (both P < 0.005). Individually analyzed after acipimox, all 14 subjects presented an enhancement in the GHRH-mediated GH peak, and 8 patients showed a response over 10 micrograms/L. In conclusion, acute FFA reduction by acipimox increased the GH secretion elicited by GHRH in chronic hypercortisolism. Elevated FFA may be a contributing factor to the deranged GH secretion observed in Cushing's syndrome.

RESUMO

OBJECTIVE: Acute diarrhea is the leading cause of pediatric morbidity and mortality worldwide. Oral rehydration treatment can prevent death from dehydration, but does not reduce the duration of individual episodes. Homeopathic treatment for acute diarrhea is used in many parts of the world. This study was performed to determine whether homeopathy is useful in the treatment of acute childhood diarrhea. METHODOLOGY: A randomized double-blind clinical trial comparing homeopathic medicine with placebo in the treatment of acute childhood diarrhea was conducted in León, Nicaragua, in July 1991. Eighty-one children aged 6 months to 5 years of age were included in the study. An individualized homeopathic medicine was prescribed for each child and daily follow-up was performed for 5 days. Standard treatment with oral rehydration treatment was also given. RESULTS: The treatment group had a statistically significant (P < .05) decrease in duration of diarrhea, defined as the number of days until there were less than three unformed stools daily for 2 consecutive days. There was also a significant difference (P < .05) in the number of stools per day between the two groups after 72 hours of treatment. CONCLUSIONS: The statistically significant decrease in the duration of diarrhea in the treatment group suggests that homeopathic treatment might be useful in acute childhood diarrhea. Further study of this treatment deserves consideration.

RESUMO

The objective of this study is to ascertain whether or not the supply of a low-calorie amino acids (AA) parenteral solution is useful in postoperative patients, by assessing a series of parameters that indicate nutritional status. 75 postoperative patients who met at least 2 of the 3 criteria: 1) albumin less than 3 g/dl; 2)prealbumin less than 21 mg/dl; 3) body weight less than 95% of ideal weight, were studied. Patients were divided into 4 groups: control group, 15 patients receiving conventional infusion therapy; group I, 20 patients receiving glucose + AA; group II, 20 patients receiving glycerol + AA; and group III, 20 patients receiving sorbitol-xylitol + AA. The most significant findings were a prompt recovery of short half-life proteins (prealbumin and retinol binding protein), a less negative nitrogen balance, a greater decrease in urinary 3-methylhistidine and a marked increase in most AAs when hypocaloric peripheral parenteral nutrition (HPPN) was used. As regards complications, suture dehiscence occurred in a greater percentage of control patients than in the active therapy groups (13.3% versus 5%) and, in contrast, a greater number of cases of infusion phlebitis was observed in the HPPN groups. Clinical data were not statistically significant. We conclude that HPPN is a valid means for providing nutritional support but, at present, there are few randomized, controlled studies that show that its use is clearly beneficial.

RESUMO

Separation conditions in CE, with a neutral coated capillary and reversed polarity, have been optimised to make direct measurement of vanillylmandelic acid, homovanillic acid and 5-hydroxyindoleacetic acid possible in urine samples without pre-treatment. The method developed has been validated, presenting adequate parameters for linearity, accuracy and precision. Detection limits range from 0.03 to 2.5 microM. Finally the method has been applied to urine samples taken from patients, both adults and children, in hospital. Some of them were also measured by immunoassay and HPLC-electrochemical detection and results have been compared.

RESUMO

OBJECTIVE: We compared the metabolic and clinical effects of two lipid emulsions, long-chain triacylglycerols (LCT) and a mixture of medium- and long-chain triacylglycerols (MCT/LCT), in septic patients. METHODS: Both groups received total parenteral nutrition (TPN) with a solution enriched with branched-chain amino acids (BCAA). Seventy-two septic patients received TPN with MCT/LCT (group 1) or LCT (group 2). Before starting TPN (basal) and 10 d after (final), various parameters were evaluated. RESULTS: Twenty-six subjects in each group completed the study. Both groups showed an increase in cholestasis enzymes, with no significant changes in lipid parameters. The rise of retinol-binding protein and the recovery of nitrogen balance were significantly greater in group 1. A multivariate analysis of nutritional markers and catabolic parameters showed a better evolution in group 1 (P = 0.002). The MCT/LCT group exhibited a significant increase of insulin levels. Overall mortality and length of stay in the intensive care unit were not affected by the lipid emulsion. CONCLUSIONS: In septic patients who received TPN with a solution enriched with BCAAs, the use of an emulsion containing MCT provided them with a greater recovery of their nutrition status than the traditional LCT formula, without influencing the outcome.

RESUMO

OBJECTIVE: To investigate whether the finding in a previous study that homeopathic medicines decrease the duration of acute diarrhea in children could be replicated in a different study population. DESIGN: Randomized, double-blind, placebo-controlled trial. SETTING: Private, charitable health clinic in Kathmandu, Nepal. SUBJECTS: A consecutive sample of 126 children, 6 months to 5 years of age, who presented during April through June, 1994, with more than three unformed stools in the previous 24 hours. INTERVENTION: Children received either an individualized homeopathic medicine or placebo, to be taken one dose after each unformed stool for 5 days. Parents recorded daily stools on diary cards, and health workers made home visits daily to monitor children. OUTCOME MEASURES: Predefined measures were based on the previous study: (1) duration of diarrhea, defined as the time until there were fewer than three unformed stools per day, for two consecutive days, and (2) Average number of stools per day for each group. RESULTS: Of the 126 children initially enrolled, 116 completed treatment. The mean number of stools per day over the entire 5-day treatment period was 3.2 for the treatment group and 4.5 for the placebo group (P = 0.023). A Kaplan-Meier survival analysis of the duration of diarrhea, which included data from all patient visits, showed an 18.4% greater probability that a child would be free of diarrhea by day 5 under homeopathic treatment (P = 0.036). CONCLUSIONS: These results are consistent with the finding from the previous study that individualized homeopathic treatment decreases the duration of diarrhea and number of stools in children with acute childhood diarrhea.

RESUMO

The present study analyzes de publicity messages with a alimentary-nutritional content (n = 448), aired by 2 television channels (one public and one private), during 6 hours a day in the first week of October 1993, examining the most frequent tendencies and errors, and whether or not they are adhering to the nutritional standards intended to improve the health of the population. With this aim, a questionnaire was designed, which was submitted to a control prior to doing the study, and which permitted the same study during the years 1991, 1992, and 1993. The message which was most used to promote the sales of the products, was the taste, followed by quality, novelty, health, nutritional and natural. The messages indicating that the product reduces or minimizes fat, cholesterol, sodium, sugar, alcohol, ... are few or lower than those observed in other populations. In some cases the messages may be useful in re-enforcing the standards of the nutritional educators and health care professionals who try to improve the diet and the health of the public. However, in the majority of cases, the message of the advertisements may mislead or confuse the consumer with irrelevant or incomplete information. They also frequently contribute to the promotion of an extremely thin body image, which guides the food choice of a large percentage of the population. The results of the study may help in the planning of nutritional education of the population, and they emphasize the need for a greater supervision and control of the advertisements.

RESUMO

A variety of studies indicate that folate deficiency is associated with the appearance of problems of a neuromuscular or neurological nature such as depression, muscular and mental fatigue, states of confusion and non-senile dementia, and that these processes improve fully or partly when the deficiency is corrected. Because of the role of folates in the reactions in synthesis of neuro-transmitter and elements of neuron structure, it is not surprising that a deficiency is associated with depression and other mental problems. Folates are involved in the synthesis of S-adenosylmethionine (SAM) which is the main contributor of methyl groups in the nervous system and whose action as an antidepressive agent is confirmed. They are also involved in the synthesis of glutamate which is an excitant neurotransmitter, and in the formation of puric and pyrimidic bases. An alternative mechanism for explaining the etiopathogenesis of folate deficiency in depression and other mental disorders involves the regeneration of tetrahydrobiopterin (THB) which is an essential cofactor in hydroxylation process in the brains of mammals. Folate deficiency is a common nutritional problem in many groups of the Spanish population and, given the role of this vitamin in the operation of the nervous system, we might consider the possibility that, in some case, folate deficiency may cause or aggravate some alterations to mental function.

RESUMO

BACKGROUND: Gallstones and neoplasms generally cause obstructions in the biliary duct. There are some infrequent problems that may lead to obstructions, such as hamartomas of the biliary duct. CASE REPORT: A 34-year-old diabetic female patient begins with abdominal pain and jaundice. The diagnostic approach initiated with hepatobiliary ultrasound that reported cholelithiasis and enlargement of the biliary ducts. Cholangiopancreatography was subsequently performed and a biliary tree lesion was discovered; the patient underwent cholecystectomy with exploration of the biliary ducts. Clinical evolution was satisfactory. Pathologic findings indicated hamartoma of the biliary duct.

RESUMO

OBJECTIVE: Case report of a malignant stromal tumor of the transverse colon. BACKGROUND: Colon sarcomas are rare; the most frequent presentation is the leiomyosarcoma. Forty five cases of malignant stromal tumor have been reported in the international literature. The histogenesis of these mesenchymatous neoplasms is determined by ultrastructural analysis and immunohistochemical stains, nevertheless when special techniques are negative and there is uncertainty related to the cellular differentiation line (smooth muscle, neural or undifferentiated) it is preferable to call them stromal tumors of gastrointestinal tract. METHOD: A 46 year old patient with the diagnosis of malignant stromal tumor of transverse colon and the prescribed treatment was reported. RESULTS: A case of a patient with the diagnosis of malignant stromal tumor in transverse colon is presented, who had as the main clinical features abdominal pain, transanal hemorrhage and finally intestinal occlusion. He was submitted to exploratory laparotomy finding a transverse colon intussusception, which was treated with an extended right hemicolectomy and a post surgical satisfactory recovery. Follow-up to three years hasn't found tumoral activity. CONCLUSIONS: Stromal tumors are rare in colon, treatment is a wide surgical resection with curative or palliative purposes.

RESUMO

Dietetic, hematologic and biochemical data were used to asses the iron status of a group of 64 adolescents (37 males and 27 females), aged 15 to 18 (mean age 15.94 +/- 0.76 years), who study in a High School in the comunidad Autónoma de Madrid. All were asked to keep a dietary record during 5 days, one of which had to be a sunday. Iron intake was estimated using the Food Composition Tables of the Instituto de Nutrición (1990). The hematologic survey determined hemoglobin hematocrit mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH), mean corpuscular hemoglobin concentration (MCHC), serum iron and serum ferritin. These data were correlated with the scores obtained in the attention and school capability test (AT), that gave information about the verbal (V), reasoning (R) and calculus (C) capabilities. There is a positive correlation between MCV (r = 0.2705), MCH (r = 0.3370) ferritin (r = 0.3383) and attention. MCV (r = 0.2995), MCH (r = 0.3998), MCHC (r = 0.3134) and ferritin (r = 0.3970) were also correlated with the speed capability shown on the attention test and the hemoglobin level was correlated with the calculus capability (r = 0.2905). The students who obtained higher scores in the school capability test had also better blood parameter values. This was statistically significant for serum ferritin in males students and for hemoglobin and MCHC in female students. 19.6% of the adolescents had ferritin levels lower than 12 ng/ml. Their intelligence test scores were lower to those who had serum ferritin > or = 12 ng/ml.(ABSTRACT TRUNCATED AT 250 WORDS)

RESUMO

PURPOSE: Prevention of parastomal hernia represents an important aim when a permanent stoma is necessary. The objective of this work is to assess whether implantation of a prophylactic prosthetic mesh during laparoscopic abdominoperineal resection contributed to reduce the incidence of parastomal hernia. METHODS: Rectal cancer patients undergoing elective laparoscopic abdominoperineal resection with permanent colostomy were randomized to placement of a large-pore lightweight mesh in the intraperitoneal/onlay position by the laparoscopic approach (study group) or to the control group (no mesh). Parastomal hernia was defined radiologically by a CT scan performed after 12 months of surgery. The usefulness of subcutaneous fat thickness measured by CT to discriminate patients at risk of parastomal hernia was assessed by ROC curve analysis. RESULTS: Thirty-six patients were randomized, 19 to the mesh group and 17 to the control group. Parastomal hernia was detected in 50 % of patients in the mesh group and in 93.8 % of patients in the control group (P = 0.008). The AUC for thickness of the subcutaneous abdominal was 0.819 (P = 0.004) and the optimal threshold 23 mm. Subcutaneous fat thickness ≥23 mm was a significant predictor of parastomal hernia (odds ratio 15.7, P = 0.010), whereas insertion of a mesh was a protective factor (odds ratio 0.06, P = 0.031). CONCLUSIONS: Use of prophylactic large-pore lightweight mesh in the intraperitoneal/onlay position by a purely laparoscopic approach reduced the incidence of parastomal hernia formation. Subcutaneous fat thickness ≥23 mm measured by CT was an independent predictor of parastomal hernia.

RESUMO

Before 2006, Pompe disease or glycogenosis storage disease type II was an incurable disease whose treatment was merely palliative. The development of a recombinant human alpha-glucosidase enzymatic replacement therapy has become the first specific treatment for this illness. The aim of this guide is to serve as reference for the management of the late-onset Pompe disease, the type of Pompe disease that develops after one year of age. In the guide a group of Spanish experts make specific recommendations about diagnosis, follow-up and treatment of this illness. With regard to diagnosis, the dried blood spots method is essential as the first step for the diagnosis of Pompe disease. The confirmation of the diagnosis of Pompe disease must be made by means of an study of enzymatic activity in isolated lymphocytes or a mutation analysis of the alpha-glucosidase gene. With regard to treatment with enzymatic replacement therapy, the experts say that is effective improving or stabilizating the motor function and the respiratory function and it must be introduced when the first symptoms attributable to Pompe disease appear.

RESUMO

Introducción Los jóvenes con discapacidad suelen ser menos activos físicamente que los jóvenes sin discapacidad y existen barreras que limitan el nivel de actividad física en su diario vivir. El propósito de esta investigación cualitativa con diseño fenomenológico fue explorar y describir la experiencia de los padres y entrenadores de equipos deportivos en Puerto Rico, en el proceso de inclusión de niños y jóvenes con síndrome de Down. Método Los participantes fueron 3 entrenadores deportivos y 3 padres de niños y/o jóvenes con síndrome de Down, cuyos hijos fueran estudiantes de los entrenadores. Se llevaron a cabo entrevistas semiestructuradas en las que se encontró que la experiencia para los padres fue positiva en términos de los beneficios físicos y sociales que brinda el realizar actividad física junto con niños o jóvenes típicos. Resultados Pudieron ser identificados diferentes barreras y facilitadores para el proceso de inclusión y los entrenadores se consideran una herramienta clave en este proceso. Los fisioterapeutas fueron identificados como facilitadores de la inclusión, por su rol como promotores de salud, desarrollo y actividad física. Conclusiones Existe un espacio de oportunidad para la creación y promoción de más programas de deporte inclusivo, y se resaltó la importancia de que profesionales de la salud como los fisioterapeutas estén involucrados en la promoción de la inclusión y educación a los padres de niños o jóvenes con síndrome de Down sobre alternativas disponibles para que sus hijos estén físicamente activos (AU)


Introduction Children and young people with disabilities are usually less physically active than young people without disabilities with barriers that limit the levels of physical activity in their daily lives. The purpose of this qualitative research with phenomenological design was to explore and describe the experience of parents and coaches of sports teams in Puerto Rico, in the inclusion process of children and young people with Down syndrome. Method The participants were 3 sports coaches and 3 parents of children and/or young people with Down syndrome, whose children were students of the coaches. Semi-structured interviews were carried out in which it was found that the experience for the parents was positive in terms of the physical and social benefits provided by performing physical activity together with typical children or young people. Results Different barriers and facilitators were identified for the inclusion process and the sports coaches are considered a key tool in this process. Physiotherapists were identified as facilitators of inclusion, due to their role as promoters of health, development, and physical activity. Conclusions There is a window of opportunity for the creation and promotion of more inclusive sports programmes, and the importance is highlighted of health professionals such as physiotherapists being involved in promoting the inclusion and education of parents of children or young people with Down syndrome on available alternatives for their children to be physically active (AU)
