RESUMO

BACKGROUND: Identifying barriers that can be modified to promote physical activity is important for informing health interventions for adults with intellectual disabilities. OBJECTIVES: Exploring participation in physical activity considering age, sex, living conditions, and health conditions. Further, identifying barriers significantly associated with sedentary activity after adjustment for physical activity correlates. METHODS: A cross-sectional study including physical activity and barrier questions from the POMONA-15 health indicators. Multivariate logistic regression analysis with sedentary activity level as dependent variable. RESULTS: Among 213 participants with intellectual disabilities, 36% reported predominately sedentary activities, 53% light and 11% moderate/vigorous physical activity. Barriers related to sedentary activity after adjustment were transportation, health conditions, mobility impairment, and lack of activities at the day activity centre. CONCLUSIONS: The findings highlight the need to enhance physical activity opportunities at day activity centres, tailor programmes for wheelchair users, and improve access to physical activity facilities for adults with intellectual disabilities.

RESUMO

BACKGROUND: Studies have found that presence of challenging behaviours and mental health problems limits employment for people with intellectual disabilities. This study investigates the associations between age, gender, living condition, level of intellectual disability, diagnoses, behaviour, mental health, and employment in adults with intellectual disabilities in Norway. METHOD: A cross-sectional community-based survey including 214 adult participants (56% men) with intellectual disabilities. RESULTS: In our sample, 25% had no organised day activity, 27% attended non-work day care, 19% attended sheltered employment, or day care with production, without pay and 29% worked in paid sheltered employment. One participant attended mainstream employment. Moderate and severe/profound level of intellectual disability, possible organic condition and irritability significantly reduced the odds of employment (paid and unpaid). CONCLUSION: Findings suggest unequal access to the sheltered employment that was meant to be inclusive. More individualised evaluation of prerequisites is suggested to further facilitate employment for this group.

RESUMO

New national guidelines recommend annual health checks for adults with intellectual disabilities. Adults with a diagnosis of intellectual disability die earlier, have poorer health and more difficulty accessing health services than the general population. Annual health checks have been recommended in Norway and internationally for many years because they help identify ill health and serious illnesses.

RESUMO

BACKGROUND: This study investigated the completion rates, scores and factors associated with non-completion and low scores on physical capability tests in a health survey administered to adults with intellectual disabilities. METHOD: Assessment comprised body mass index (BMI), the Short Physical Performance Battery (SPPB), the timed up-and-go (TUG) test, the one-legged stance (OLS) test; and gross motor, communication and behavioural functioning tests. RESULTS: The completion rates among 93 participants (aged 17-78) were 46% for the SPPB, 42% for the TUG, and 31% for the OLS. More severe intellectual disability (OR = 3.12, p < .001) and lower BMI (OR = 0.859, p = .001) were related to test non-completion. The SPPB scores were below the reference values from the general population. Lower scores were associated with older age, motor disabilities and intellectual disability severity. CONCLUSIONS: Including physical capability tests in health surveys among adults with intellectual disabilities is important to monitor functional status and guide prevention strategies.

RESUMO

A simple and effective approach for HPLC-MS/MS based multi-mycotoxin analysis in human urine samples was developed by application of dried urine spots (DUS) as alternative on-site sampling strategy. The newly developed method enables the detection and quantitation of 14 relevant mycotoxins and mycotoxin metabolites, including citrinin (CIT), dihydrocitrinone (DH-CIT), deoxynivalenol (DON), fumonisin B1 (FB1), T-2 Toxin (T-2), HT-2 Toxin (HT-2), ochratoxin A (OTA), 2'R-ochratoxin A (2'R-OTA), ochratoxin α (OTα), tenuazonic acid and allo-tenuazonic acid (TeA + allo-TeA), zearalenone (ZEN), zearalanone (ZAN), α-zearalenol (α-ZEL), and ß-zearalenol (ß-ZEL). Besides the spotting procedure, sample preparation includes enzymatic cleavage of glucuronic acid conjugates and stable isotope dilution analysis. Method validation revealed low limits of detection in the range of pg/mL urine and excellent apparent recovery rates for most analytes. Stability investigation of DUS displayed no or only slight decrease of the analyte concentration over a period of 28 days at room temperature. The new method was applied to the analysis of a set of urine samples (n = 91) from a Swedish cohort. The four analytes, DH-CIT, DON, OTA, and TeA + allo-TeA, could be detected and quantified in amounts ranging from 0.06 to 0.97 ng/mL, 3.03 to 136 ng/mL, 0.013 to 0.434 ng/mL and from 0.36 to 47 ng/mL in 38.5%, 70.3%, 68.1%, and 94.5% of the samples, respectively. Additional analysis of these urine samples with an established dilute and shoot (DaS) approach displayed a high consistency of the results obtained with both methods. However, due to higher sensitivity, a larger number of positive samples were observed using the DUS method consequently providing a suitable approach for human biomonitoring of mycotoxin exposure.

RESUMO

BACKGROUND: Individuals with intellectual disabilities (IDs) have lower levels of physical activity (PA) and greater barriers for participation in fitness activities compared with members of the general population. As increased PA has positive effects on cardiovascular and psychosocial health, it is exceedingly important to identify effective interventions for use in everyday settings. Mobile health (mHealth) methods such as motion sensor games (exergames) and smartphone reminders for PA have been explored and found to be promising in individuals with IDs. OBJECTIVE: The purpose of this study is to examine the effectiveness of an individually tailored PA program with motivational mHealth support on daily levels of PA in youth and adults with IDs. METHODS: The trial uses a randomized controlled design comprising 30 intervention participants and 30 control group participants, aged 16 to 60 years, with sedentary lifestyles or low PA levels. While the controls will receive standard care, the intervention aims to increase the level of PA, measured as steps per day, as the primary outcome. Secondary outcome variables are body mass index, blood pressure, physical performance, social support for PA, self-efficacy in a PA setting, behavior problems, and goal attainment. The intervention involves the delivery of tailored mHealth support, using smartphones or tablets to create structure with focus on the communicative abilities of individual participants. Rewards and feedback are provided in order to motivate individuals to increase participation in PA. Participants in the intervention group, their close relatives, and care staff will be invited to participate in a preintervention goal-setting meeting, where goal attainment scaling will be used to select the participants' PA goals for the intervention period. All participants will be assessed at baseline, at 3 months, and at 6 months. RESULTS: Enrollment was planned to start in April 2020 but will be delayed due to the pandemic situation. The main contribution of this paper is a detailed plan to run our study, which will produce new knowledge about tailored mHealth to support PA in individuals with intellectual disabilities. CONCLUSIONS: We expect the new intervention to perform better than standard care in terms of improved PA, improved self-efficacy, and social support for activities. Technology offers new opportunities to promote healthy behaviors. The results of the study will determine the effectiveness and sustainability of a tailored mHealth support intervention to increase PA in youth and adults with IDs.

RESUMO

The exposure to mycotoxins of Swedish adolescents is currently unknown. The aim of the present study was to investigate the exposure to mycotoxins and their association with food intake, and background characteristics in adolescents of a national dietary survey. About 3000 school students (1000 from the 5th, 8th and 11th school years) were recruited for the survey. The participants completed Web-based questionnaires on food propensity, sociodemography and health, and a Web-based dietary recall. Spot urine and blood samples were collected from 1105 of the participants for mycotoxin biomarker analysis. Mycotoxins were analysed with multibiomarker methods in urine (HPLC-MS/MS) and serum (HPLC-MS/MS). Of the 35 different analytes in urine, the frequency of positive samples were the following: deoxynivalenol (DON, 4.8%), DON-15-ß-D-O-glucuronide (DON-15GlcA, 9.1%), dihydro-citrinone (DH-CIT, 0.5%), HT-2-glucuronide (HT-2-3-GlcA, 0.1%) and ochratoxin A (OTA, 0.1%). Of the 27 different analytes in serum, OTA was detected in all samples, while 2'R-ochratoxin A (2'R-OTA) was found in 8.3% and enniatin B (EnB) in 99.2% of the samples. Exposure assessment calculations were performed on OTA from the serum concentration and on DON equivalents (DON eqv) from the urine concentration. All probable daily intake (PDI) estimates were below tolerable daily intakes, except for 1.6% of the participants for DON. The maximum PDI was 4.3 µg DON eqv/kg body weight and day. Consumption of cereal grain commodities was associated with levels of DON, EnB or OTA in biofluids. Serum OTA was also associated with intakes of raisins and coffee. Furthermore, coffee consumption correlated well with 2'R-OTA concentration in serum. In conclusion, exposure to mycotoxins in Swedish adolescents is common, but fortunately, high exposure was rare.

RESUMO

The determination of mycotoxin and metabolite concentrations in human and animal urine is currently used for risk assessment and mycotoxin intake measurement. In this study, pig urine (n = 195) was collected at slaughterhouses in 2012 by the Swedish National Food Agency in three counties representing East, South and West regions of Sweden. Urinary concentrations of four mycotoxins, (deoxynivalenol (DON), zearalenone (ZEA), fumonisin B1 (FB1), and ochratoxin A (OTA)), and four key metabolites, (deepoxy-deoxynivalenol (DOM-1), aflatoxin M1 (AFM1, biomarker of AFB1), α-zearalenol (α-ZOL), and ß-zearalenol (ß-ZOL)) were identified and measured by UPLC-MS/MS. Statistically significant regional differences were detected for both total DON (DON + DOM-1) and total ZEA (ZEA + α-ZOL + ß-ZOL) concentrations in pig urine from the three regions. These regional differences were in good agreement with the occurrence of Fusarium graminearum mycotoxins (DON + ZEA) in cereal grains harvested in 2011 in Sweden. There were no statistically significant differences in FB1, AFM1 and OTA urinary concentrations in pigs from the three regions. The overall incidence of positive samples was high for total ZEA (99-100%), total DON (96-100%) and OTA (85-95%), medium for FB1 (30-61%) and low for AFM1 (0-13%) in the three regions. Urinary mycotoxin biomarker concentrations were used to estimate mycotoxin intake and the level of mycotoxins in feeds consumed by the monitored pigs. The back-calculated levels of mycotoxins in feeds were low with the exception of seven samples that were higher the European limits.

RESUMO

Estimations of consumer exposure to mycotoxins through surveillance of mycotoxins in the food trade are well described, but the exposure due to mouldy food in private homes is not known, and may result from removing visible mould on food and eating the rest. In this study, we followed the growth of Penicillium expansum on the surface of apple jam and Penicillium verrucosum on crème fraiche, as well as production and distribution of fungal metabolites throughout the sample (approx. 6 cm high divided into three equal layers), using a multianalyte method, over time (up to 28 days) and at 4, 8 and 15 °C. Growth rates and apparent lag times for P. expansum in apple jam at different temperatures were estimated by fitting to the Baranyi model. The growth rates were 1.7, 2.7 and 4.3 mm day-1 for storage at 4, 8 and 15 °C, respectively; apparent lag times decreased with increasing storage temperature and were 10.6, 7.9 and 2.6 days at corresponding temperatures. Patulin and roquefortine C were identified and quantified, among other fungal metabolites. Patulin was detected in all 2-cm layers of the apple jam at 15 °C. Concentrations in the upper two layers of the jar corresponded to exposures exceeding the health based guidance value (HBGV) for a normal serving size. Consequently, removal of the mouldy part is insufficient to avoid unhealthy exposure. In contrast to patulin, roquefortine C was also produced at 4 °C. The growth of P. verrucosum on crème fraiche was very restricted and could not be modelled. Despite the small colony (8 ±â€¯0.5 mm in diameter), ochratoxin A and citrinin were detected after 21 days at 15 °C in the top 2 cm layer (including the fungal colony), and at concentrations in a normal serving corresponding to an exposure above the HBGV established by EFSA for both mycotoxins. Questiomycin A, an antibiotic, was also produced in crème fraiche but in contrast to the two mycotoxins, was detected throughout all layers of the crème fraiche and was produced also at 4 and 8 °C. As a complement to a previous study, we also present production and the distribution of major fungal metabolites in apple jam and crème fraiche for some additional fungal strains (P. crustosum, P. roqueforti and P. verrucosum on apple jam and P. expansum on crème fraiche). A pilot study investigating the effect of inoculation size on toxin production may have implications for the best inoculum to use in experimental studies.

RESUMO

Deoxynivalenol (DON) exposure is estimated by the combined measures of urinary DON and DON-glucuronides. In this study, data from single-mycotoxin (SM) and a multimycotoxin (MM) methods were compared for 256 Swedish adult urine samples. Both methods included ß-glucuronidase predigestion, immunoaffinity enrichment, and LC-MS/MS. However, the specific reagents, apparatus, and conditions were not identical in part because the MM method measures additional mycotoxins. DON was detected in 88 and 63% of samples using the SM and MM methods, respectively, with the following mean and median concentrations: SM, mean = 5.0 ng/mL, SD = 7.4, range of positives = 0.5-60.2 ng/mL, median = 2.5 ng/mL, IQR = 1.0-5.5 ng/mL; MM, mean = 4.4 ng/mL, SD = 12.9, range of positives = 0.5-135.2 ng/mL, median = 0.8 ng/mL, IQR = 0.3-3.5. Linear regression showed a significant, albeit modest, correlation between the two measures (p = 0.0001, r = 0.591). The differences observed may reflect subtle handling differences in DON extraction and quantitation between the methods.

RESUMO

Extracorporeal membrane oxygenation (ECMO) has been reported as an alternative to cardiopulmonary bypass during lung transplantation. The reports in the literature have been limited to adult practice and associated with decreased pulmonary and renal complications, lower mortality, and lower in-hospital mortality. We present four pediatric lung transplantations performed on ECMO and discuss relevant perfusion management.

RESUMO

BACKGROUND: We reviewed the outcomes of patients who underwent cardiopulmonary support (CPS) for either refractory sudden cardiac arrest or failure to wean from cardiopulmonary bypass (CPB). METHODS: Between January 2005 and July 2013, 37 patients with congenital heart disease (CHD) underwent 39 instances of CPS for sudden cardiac arrest as extracorporeal cardiopulmonary resuscitation (E-CPR; group I, n = 19) or for failure to wean from CPB (group II, n = 20). Univariate analyses determined which variables differed among the groups and which had significant association with hospital survival. Binary logistic regression determined the significant associations in a multivariable model. RESULTS: Overall 30-day and hospital survival were 76.9% (30) and 69.2% (27), respectively. For groups I and II, hospital survival was 68.4% (13) and 70.0% (14), respectively. Variables associated with mortality in the univariate analysis included hours on CPS (P = .045), initial aspartate aminotransferase (AST) level on CPS (P = .007), and bicarbonate 24 hours on CPS (P = .004). Logistic regression showed single-ventricle physiology (P = .05), initial AST level on CPS (P = .03), and lower bicarbonate 24 hours on CPS (P = .026) to be significantly associated with mortality. CONCLUSIONS: Comparable rates of survival to discharge can be obtained when CPS is initiated for E-CPR or for failure to wean from CPB in resuscitating patients with CHD. Hepatic and renal factors indicative of inadequate early tissue perfusion, single-ventricle physiology, and lower bicarbonate level are factors associated with poor outcome.

RESUMO

BACKGROUND: An optimal selective cerebral perfusion protocol in pediatric cardiac surgery is unknown. Phentolamine is frequently used in pediatric cardiopulmonary bypass. We sought to determine the effects of continuous phentolamine infusion during selective cerebral perfusion. METHODS: Twenty-seven neonatal piglets (3.38 ± 0.32 kg) were randomly assigned to 3 groups; sham (n = 7, anesthesia alone, no surgery or bypass), control (n = 10, saline infusion), or experimental (n = 10, phentolamine infusion 0.1 mg/kg per hour). Animals underwent 90 minutes of selective cerebral perfusion. Cerebral vascular resistance index (CVRI) and metabolic rate of oxygen (CMRO2) were determined every 15 minutes. Standardized sections of hippocampus, basal ganglia, and neo-cortex were obtained. Tissue samples were stained for caspase-3 and analyzed for positive apoptotic cell count. Data were analyzed with repeated measures and one-way analysis of variance. RESULTS: The CVRI tended to increase over time in the control group and decrease over time in the experimental group, but difference was not statically significant (0.46 ± 0.24 vs 0.39 ± 0.10 mm Hg × min × kg(2/3)/mL, p = 0.15). Mean CMRO2 was higher in the control group compared with the experimental group (0.90 ± 0.27 vs 0.59 ± 0.12 mLO2/min × kg(2/3), p = 0.005) and decreased over time in both groups. The percentage of caspase-3 positive cells was significantly different among regions (hippocampus = 16.9 ± 8.8; basal ganglia = 14.6 ± 7.5; neocortex = 10.8 ± 6.3; p < 0.0001) but not significantly different among sham (11.8% ± 2.68%), control (14.4% ± 2.24%), and experimental (15.5% ± 2.24%) groups. CONCLUSIONS: A continuous infusion of phentolamine during selective cerebral perfusion significantly decreases CMRO2 and tends to decrease CVRI when compared with control. At the dose studied and at the time of tissue sampling, phentolamine does not appear to decrease apoptosis during or early after selective cerebral perfusion.

RESUMO

Wheat is often infected by Fusarium species producing mycotoxins, which may pose health risks to humans and animals. Deoxynivalenol (DON) is the most important Fusarium toxin in Swedish wheat and has previously been shown to be produced mainly by Fusarium graminearum. However, less is known about the co-occurrence of DON and F. graminearum with other toxins and Fusarium species in Sweden. This study examined the distribution of the most important toxigenic Fusarium species and their toxins in winter wheat (2009 and 2011) and spring wheat (2010 and 2011). DNA from seven species was quantified with qPCR and the toxin levels were quantified with a multitoxin analysis method based on liquid chromatography/electrospray ionisation-tandem mass spectrometry (HPLC/ESI-MS/MS). The method enabled detection of many fungal metabolites, including DON, zearalenone (ZEA), nivalenol (NIV), T-2 toxin, HT-2 toxins, moniliformin (MON), beauvericin (BEA), and enniatins (ENNs). It was found that Fusarium poae and Fusarium avenaceum were present in almost all samples. Other common Fusarium species were F. graminearum and F. culmorum, present in more than 70% of samples. Several species occurred at lower DNA levels in 2011 than in other years, but the reverse was true for F. graminearum and Fusarium langsethiae. The most prevalent toxins were ENNs, present in 100% of samples. DON was also common, especially in spring wheat, whereas ZEA and NIV were common in 2009 and in winter wheat, but less common in 2011 and in spring wheat. Only three samples of spring wheat contained T-2 or HT-2 above LOQ. Annual mean levels of several mycotoxins were significantly lower in 2011 than in other years, but the reverse applied for DON. The strongest correlations between mycotoxin and Fusarium DNA levels were found between F. avenaceum and ENNs (r(2) = 0.67) and MON (r(2) = 0.62), and F. graminearum and DON (r(2) = 0.74). These results show that several Fusarium species and toxins co-occur in wheat. The highest toxin levels were detected in spring wheat and DON and ENNs, the latter belonging to the group of so called "emerging toxins", which were the most prevalent toxins and those occurring at the highest levels.

RESUMO

Fusarium moulds frequently contaminate oats and other cereals world-wide, including those grown in Northern Europe. To investigate the presence of toxigenic Fusarium species and their toxins in oats, samples were taken during 2010 and 2011 in three geographical regions of Sweden (east, west, south). The samples were analysed by real-time PCR for the specific infection level of seven Fusarium species associated with oats and other cereals (Fusarium poae, Fusarium graminearum, Fusarium langsethiae, Fusarium culmorum, Fusarium tricinctum, Fusarium sporotrichioides and Fusarium avenaceum) and with a multi-mycotoxin method based on liquid chromatography/electrospray ionisation-tandem mass spectrometry (HPLC/ESI-MS/MS) for the detection of many fungal metabolites, including deoxynivalenol (DON), zearalenone (ZEA), nivalenol (NIV), T-2 toxin, HT-2 toxins, moniliformin (MON), beauvericin (BEA) and enniatins (ENNs). Most samples contained at least four of the seven Fusarium species analysed and F. poae, F. langsethiae and F. avenaceum were present in approximately 90-100% of all samples. The most common toxins detected were DON, NIV, BEA and ENNs, which were present in more than 90% of samples. Most Fusarium species and their toxins occurred in higher concentrations in 2010 than in 2011, with the exception of DON and its main producer F. graminearum. Significant regional differences were detected for some moulds and mycotoxins, with higher levels of F. graminearum, DON and ZEA in western Sweden than in the east (P<0.05) and higher levels of F. tricinctum and MON in the south (P<0.05). Correlation analysis showed significant correlations between many Fusarium species and toxin levels. For example, F. tricinctum was significantly correlated to F. avenaceum (r = 0.72, P<0.001), DON to ZEA (r = 0.52, P<0.001), DON to F. graminearum (r = 0.77, P<0.001) and the sum of T-2 and HT-2 to F. langsethiae (r = 0.77, P<0.001). The multi-toxin approach employed allowed simultaneous detection of many Fusarium mycotoxins in each sample. In combination with real-time PCR analysis of seven toxigenic Fusarium spp., the results gave an overall picture of the presence of Fusarium and their toxins in Swedish oats and revealed significant annual and regional differences. This is the first study of the so-called emerging mycotoxins (e.g., ENNs, MON and BEA) in oats grown in Sweden.

RESUMO

Severe malarial infection is associated with impaired cardiac function. We report a child who underwent repair of tetralogy of Fallot two weeks after being treated for malaria. The postoperative course was complicated by impaired left ventricular function. The pathogenesis of malaria is discussed as well as the potential complications of cardiopulmonary bypass (CPB).

RESUMO

Patients with heparin-induced thrombocytopenia (HIT) that require anticoagulation for cardiovascular procedures represent a challenging and high-risk group. Bivalirudin and argatroban have been successfully used as alternative anticoagulants in adult patients with HIT. There have been few experiences published involving the pediatric population and controversy exists regarding the properties and optimal dosing of these drugs. This report describes the experience of managing two pediatric patients with HIT that underwent cardiovascular procedures requiring anticoagulation. Bivalirudin was used in both cases for anticoagulation during cardiopulmonary bypass, while argatroban was used without complications during cardiac catheterization. A description of perfusion and anticoagulation protocols is included.

RESUMO

OBJECTIVE: To report two patients helicopter transport on mechanical cardiopulmonary support to a transplant center. SETTING: Cardiac intensive care unit (CICU) and transport helicopter. PATIENTS: A 9 kg and 22 kg children who suffer cardiac deterioration needing air transport on mechanical cardiopulmonary support. INTERVENTIONS AND RESULTS: CPS was initiated to support these patients failing cardiac function. Transport on CPS of these two patients to a transplant institution was accomplished after determining that heart transplantation would be their more likely chance for recovery. CONCLUSION: A cardiac deterioration event that will lead to the need for heart transplantation can be acute and sudden sparing no time for early referral to a transplant center. It is necessary for heart centers to have a plan of action to provide inter-hospital transport on cardiopulmonary support (CPS). This protocol can involve transport by the referral institution, the receiving institution or a third institution.

RESUMO

BACKGROUND: Studies demonstrate that cardiopulmonary bypass (CPB) causes intraoperative and postoperative hyperglycemia. Hyperglycemia has been associated with morbidity and mortality after infant cardiac surgery. We studied the effects on early postoperative outcomes of glucose (GLU) changes during and after pediatric cardiac surgery. METHODS: The records of 144 infants less than 10 kg who underwent CPB for a variety of congenital cardiac procedures were reviewed. The GLU values (at multiple intervals during and after surgery), age, weight, CPB time, ultrafiltration volume, and risk adjustment for congenital heart surgery (RACHS-1) score were recorded. Univariate and multivariate linear and binary logistic regression were used to examine the dependence of the composite outcome mortality or postoperative infection, the mechanical ventilation time (VENT time), and the length of stay (LOS), on these variables. RESULTS: The RACHS-1 score was the only significant predictor of the composite variable "mortality or infection" (p = 0.008). Glucose at any time was not a significant factor predicting this outcome. Lower pre-CPB GLU, younger age, and higher RACHS-1 score were significant predictors of greater LOS and VENT time. CONCLUSIONS: In this study, post-CPB and postoperative hyperglycemia were not risk factors for postoperative morbidity and mortality after infant cardiac surgery.
