RESUMO

BACKGROUND: There is a need for effective primary care interventions that help older people combat frailty and build resilience. OBJECTIVE: To study the effectiveness of an optimised exercise and dietary protein intervention. DESIGN: Multicentre, randomised-controlled, parallel-arm trial. SETTING: Six primary care practices, Ireland. METHODS: Six general practitioners enrolled adults aged 65+ with Clinical Frailty Scale score ≤5 from December 2020 to May 2021. Participants were randomised to intervention or usual care with allocation concealed until enrolment. Intervention comprised a 3-month home-based exercise regime, emphasising strength, and dietary protein guidance (1.2 g/kg/day). Effectiveness was measured by comparing frailty levels, based on the SHARE-Frailty Instrument, on an intention-to-treat basis. Secondary outcomes included bone mass, muscle mass and biological age measured by bioelectrical impedance analysis. Ease of intervention and perceived health benefit were measured on Likert scales. RESULTS: Of the 359 adults screened, 197 were eligible and 168 enrolled; 156 (92.9%) attended follow-up (mean age 77.1; 67.3% women; 79 intervention, 77 control). At baseline, 17.7% of intervention and 16.9% of control participants were frail by SHARE-FI. At follow-up, 6.3 and 18.2% were frail, respectively. The odds ratio of being frail between intervention and control groups post-intervention was 0.23 (95% confidence interval: 0.07-0.72; P = 0.011), adjusting for age, gender and site. Absolute risk reduction was 11.9% (CI: 0.8%-22.9%). Number needed to treat was 8.4. Grip strength (P < 0.001) and bone mass (P = 0.040) improved significantly. 66.2% found the intervention easy, 69.0% reported feeling better. CONCLUSION: A combination of exercises and dietary protein significantly reduced frailty and improved self-reported health.

RESUMO

The aim of the study was to identify dietary patterns (DP) and examine differences in anthropometric measures, blood pressure (BP), cardiorespiratory fitness and nutritional knowledge of 6- and 10-year-old children at baseline and following a nutrition and physical activity intervention, with respect to DP and treatment group. This is a longitudinal study. Food diary, nutritional knowledge questionnaire and 550-m walk/run test measured dietary intake, nutritional knowledge and cardiorespiratory fitness, respectively. BP, weight, height and waist circumference were also measured and BMI and waist-to-height ratio (WHtR) were derived. All measurements were performed at baseline and following intervention. Two primary schools (one intervention, one control) in Cork, Ireland, were selected. Participants were 6- (n 39, age 5·9 (sd 0·6) years) and 10- (n 49, age 9·8 (sd 0·5) years)-year-olds. Two DP were identified, using k-means cluster analysis, for both 6- (unhealthy and nutrient-dense) and 10-year-olds (processed and Western diet) at baseline. DP derived post-intervention were (1) plant-based and (2) processed foods for 6-year-olds and (1) nutrient-dense and (2) unhealthy for 10-year-olds. There was no statistically significant difference in DP for 6- and 10-year-olds at baseline and post-intervention (P > 0·05). Following the intervention, a multivariate ANOVA showed there were no statistically significant differences in nutritional knowledge, BMI, WHtR, cardiorespiratory fitness and BP based on DP and intervention/control group for both age groups (P > 0·05). Three out of four dietary patterns identified for 6- and 10-year-olds were unfavourable. While no statistically significant evidence of intervention impact was found on DP, a positive trend was emerging among 10-year-olds.

RESUMO

Competence in fundamental motor skills (FMS) facilitates physical activity participation and is important for children's holistic development. This study aimed to systematically review the FMS levels of children worldwide, using the Test of Gross Motor Development-2 (TGMD-2). In accordance with PRISMA guidelines, studies were identified from searches across 7 databases. Studies were required to: (i) include typically developing children (3-10 years), (ii) be published in English, (iii) have been published between 2004 and 2019 and, (iv) report ≥1 TGMD-2 outcome scores. Extracted data were evaluated based on importance of determinants, strength of evidence, and methodological quality. Data from 64 articles were included. Weighted mean (and standard deviation) scores were calculated for each FMS outcome score. Analyses revealed FMS competence increases across age during childhood, with greater proficiency in locomotor skills than object control skills. Additionally, boys exhibit higher object control skill proficiency than girls. Compared to TGMD-2 normative data, children demonstrate "below average" to "average" FMS levels. This review highlights the scope for FMS development among children worldwide. These findings reinforce the necessity for FMS interventions in early educational settings, as FMS competence is positively associated with physical activity and other health outcomes.

RESUMO

McGahan, J, Burns, C, Lacey, S, Gabbett, T, and Neill, CO. Investigation in to the positional running demands of elite Gaelic football players: How competition data can inform training practice. J Strength Cond Res 34(7): 2040-2047, 2020-This study investigated the positional running demands of elite Gaelic football players during match play and compared these demands with typical training activities used to prepare players for competition. Global positioning system (GPS) data were obtained from 30 elite Gaelic football players (26.9 ± 3.5 years, 182.8 ± 6.1 cm, 84.6 ± 8.1 kg) across a full season (13 competitive games and 78 training sessions). Only players who completed the full match and respective training sessions were included (n = 107 match files and n = 1,603 training files). Data were collected using 4-Hz GPS units (VX Sport, Lower Hutt, New Zealand). Mean high speed (≥17 km·h; m·min), mean speed (m·min), percentage at high speed (%), and mean sprint efforts (≥17 km·h; no.·min) were recorded. Running variables were analyzed across the 5 outfield positional lines in Gaelic football (full back [FB], half back [HB], midfield [MF], half forward, and full forward [FF]). For mean high-speed running and mean speed, significant relationships (range r = 0.811-0.964 and r = 0.792-0.998, respectively) were found between competition and game-based training for players in the FB, HB, MF, and FF lines (p ≤ 0.05). Analyses of mean sprint efforts and percentage at high speed found positive correlations between competition and training activities across each of the positional lines. Appropriately designed training activities can ensure that the position-specific demands of elite Gaelic football competition are met using a game-based training approach. Collectively, these findings demonstrate the value of and provide support for the use of a game-based training approach as a method of preparing players for the physical demands of competition in elite Gaelic football.

RESUMO

OBJECTIVE: To assess the effectiveness of a nutrition and physical activity (PA) intervention on dietary intake (DI), nutritional knowledge (NK), blood pressure (BP), anthropometric measures and cardiorespiratory fitness (CRF) of schoolchildren. DESIGN: Longitudinal study. DI, NK, BMI, waist-to-height ratio (WHtR), BP and CRF were all measured/calculated prior to (October 2014) and at the end of (June 2016) intervention delivery. SETTING: Two primary schools (one intervention and one control), Cork, Ireland. PARTICIPANTS: Six-year-olds (n 49; mean age = 6·09 (sd 0·33) years) and 10-year-olds (n 52; mean age = 9·90 (sd 0·37) years). RESULTS: There was a large and a moderate statistically significant difference between the change in systolic (P = 0·005, effect size (ES) = 0·165) and diastolic BP (P = 0·023, ES = 0·116), respectively, for 10-year-olds in the intervention and control groups. There was also a large statistically significant difference between the change in WHtR (P = 0·0005, ES = 0·386) and a moderate statistically significant difference between the change in NK (P = 0·027, ES = 0·107) for 10-year-olds in the intervention and control groups. There was a large statistically significant difference between the change in percentage of energy from protein in 10-year-old females (P = 0·021, ES = 0·276) in the intervention and control groups. CONCLUSIONS: Project Spraoi is Ireland's first ever school-based intervention that has been evaluated and proven effective in improving DI, NK, WHtR and BP in older primary-school children in one intervention school.

RESUMO

BACKGROUND: Cardiometabolic (CM) risk factors are heritable and cluster in individuals. We hypothesized that CM risk factors are associated with multiple shared and unique mRNA and microRNA (miRNA) signatures. We examined associations of mRNA and miRNA levels with 6 CM traits: body mass index, HDL-cholesterol and triglycerides, fasting glucose, and systolic and diastolic blood pressures through cross-sectional analysis of 2812 Framingham Heart Study who had whole blood collection for RNA isolation for mRNA and miRNA expression studies and who consented to genetic research. We excluded participants taking medication for hypertension, dyslipidemia, or diabetes. We measured mRNA (n = 17,318; using the Affymetrix GeneChip Human Exon 1.0 ST Array) and miRNA (n = 315; using qRT-PCR) expression in whole blood. We used linear regression for mRNA analyses and a combination of linear and logistic regression for miRNA analyses. We conducted miRNA-mRNA coexpression and gene ontology enrichment analyses to explore relations between pleiotropic miRNAs, mRNA expression, and CM trait clustering. RESULTS: We identified hundreds of significant associations between mRNAs, miRNAs, and individual CM traits. Four mRNAs (FAM13A, CSF2RB, HIST1H2AC, WNK1) were associated with all 6 CM traits (FDR < 0.001) and four miRNAs (miR-197-3p, miR-328, miR-505-5p, miR-145-5p) were associated with four CM traits (FDR < 0.05). Twelve mRNAs, including WNK1, that were coexpressed with the four most pleiotropic miRNAs, were also miRNA targets. mRNAs coexpressed with pleiotropic miRNAs were enriched for RNA metabolism (miR-505-5p), ubiquitin-dependent protein catabolism (miR-197-3p, miR-328) and chromatin assembly (miR-328). CONCLUSIONS: We identified mRNA and miRNA signatures of individual CM traits and their clustering. Implicated transcripts may play causal roles in CM risk or be downstream consequences of CM risk factors on the transcriptome. Studies are needed to establish whether or not pleiotropic circulating transcripts illuminate causal pathways for CM risk.

RESUMO

The study objective was to evaluate the safety and effects of Lepicol® (pysllium fibre, inulin and 5 probiotic strains) in adults with chronic, functional constipation during a 4 week intervention. 69 subjects with functional constipation according to Rome III criteria were randomised to receive Lepicol (n = 35) or placebo (n = 34) daily. Both groups had improved frequency of bowel movements, with an increase of 1.082 bowel movements in the Lepicol group over placebo after one week, and 1.079 more than placebo after week 2, but with no significant difference at week 4. Both groups showed significant improvements in quality of life scores at 4 weeks, with the average score being 12.033% better in the Lepicol group, which also had 15.2% improvement in intensity of symptoms and 28.5% increase in satisfaction with quality of life compared to the placebo. Symptoms of constipation improved to a greater degree and there was a significant reduction in laxative use in the Lepicol group.

RESUMO

Polyunsaturated fatty acids have been associated with beneficial influences on cardiovascular health. However, the underlying mechanisms are not clear, and data on the relations of polyunsaturated fatty acids to subclinical disease measures such as vascular stiffness and cardiac function are sparse and inconclusive. In a large community-based cohort, we examined the relations of omega-3 and other fatty acids to a comprehensive panel of vascular function measures (assessing microvascular function and large artery stiffness), cardiac structure and left ventricular function. Red blood cell (RBC) membrane fatty acid composition, a measure of long-term fatty acid intake, was assessed in participants of the Framingham Offspring Study and Omni cohorts and related to tonometry-derived measures of vascular stiffness and to a panel of echocardiographic traits using partial correlations. Up to n=3055 individuals (56% women, mean age 66 years) were available for analyses. In age- and sex-adjusted models, higher RBC omega-3 content was moderately associated (p≤0.002) with several measures of vascular stiffness and function in a protective direction. However, after multivariable adjustment, only an association of higher RBC omega-3 content with lower carotid-femoral pulse wave velocity (a measure of aortic stiffness) remained significant (r = -0.06, p=0.002). In secondary analyses, higher linoleic acid, the major nutritional omega-6 fatty acid, was associated with smaller left atrial size, even after multivariable adjustment (r = -0.064, p<0.001). In conclusion, in our cross-sectional community-based study, we found several associations consistent with the notion of protective effects of omega-3 and linoleic acid. The clinical significance of these modest associations remains to be elucidated.

RESUMO

BACKGROUND: When an influenza pandemic occurs most of the population is susceptible and attack rates can range as high as 40-50 %. The most important failure in pandemic planning is the lack of standards or guidelines regarding what it means to be 'prepared'. The aim of this study was to assess the preparedness of acute hospitals in the Republic of Ireland for an influenza pandemic from an infection control perspective. METHODS: This was a cross sectional study involving a questionnaire completed by infection control nurses, time period from June - July 2013, (3 weeks) from acute public and private hospitals in the Republic of Ireland. A total of 46 out of 56 hospitals responded to the questionnaire. RESULTS: From a sample of 46 Irish hospitals, it was found that Irish hospitals are not fully prepared for an influenza pandemic despite the 2009 Influenza A (H1N1) pandemic. In 2013, thirty five per cent of Irish hospitals have participated in an emergency plan or infectious disease exercise and have plans or been involved in local planning efforts to care for patients at non-health care facilities. Sixty per cent of Irish hospitals did not compile or did not know if the hospital had compiled a "lessons learned" from any exercise that were then used to revise emergency response plans. Fifty two per cent of hospitals have sufficient airborne isolation capacity to address routine needs and have an interim emergency plan to address needs during an outbreak. Fifty one percent of hospitals have taken specific measures to stockpile or have reserve medical supplies e.g. masks, ventilators and linen. CONCLUSIONS: This is the first study carried out in the Republic of Ireland investigating the current preparedness for an influenza pandemic from an infection control perspective. Deficits exist in the provision of emergency planning committees, testing of emergency plans, airborne isolation facilities, stockpiling of personal protective equipment (PPE) and medical supplies and organisational schemes/incentives for healthcare workers to continue to work in a pandemic. While Irish standards are comparable to findings from international studies, the health care service needs to continue to enhance preparedness for an influenza pandemic and implement standard preparedness guidance for all Irish hospitals.

RESUMO

Partial hand amputation can have a tremendous range of impact and functional loss on a person's life. One solution to improve function and address some of the problems that partial hand amputees face is to fit them with a prosthesis. Partial hand prosthetic devices range in a wide spectrum in both function and aesthetics. At this time, there is no one, perfect prosthetic device that can replace what is lost. Many individuals with partial hand amputation require more than one prosthetic device. In this review article, we explored and compared several prosthetic options that have been investigated and marketed by researchers and companies. Some of these options include passive, body-powered, activity-specific, and externally-powered prostheses. Lastly, we described our experiences with partial hand prostheses at Walter Reed National Military Medical Center.

RESUMO

Delayed onset muscle soreness (DOMS) due to intense physical exertion can negatively impact contractility and performance. Previously, NPN_1 (PeptiStrong™), a Vicia faba hydrolysate derived from a protein concentrate discovered through artificial intelligence (AI), was preclinically shown to help maintain muscle health, indicating the potential to mediate the effect of DOMS and alter molecular markers of muscle damage to improve recovery and performance. A randomised double-blind placebo-controlled trial was conducted on 30 healthy male (30-45 years old) volunteers (NCT05159375). Following initial strength testing on day 0, subjects were administered either placebo or NPN_1 (2.4 g/day). On day 14, DOMS was induced using resistance exercise. Strength recovery and fatigue were measured after 48 and 72 h. Biomarker analysis was performed on blood samples collected prior to DOMS induction and 0, 2, 48 and 72 h post-DOMS induction. NPN_1 supplementation significantly improved strength recovery compared to placebo over the 72 h period post-resistance exercise (p = 0.027), measured by peak torque per bodyweight, but not at individual timepoints. Muscle fatigue was significantly reduced over the same 72 h period (p = 0.041), as was myostatin expression (p = 0.006). A concomitant increase in other acute markers regulating muscle protein synthesis, regeneration and myoblast differentiation was also observed. NPN_1 significantly improves strength recovery and restoration, reduces fatigue and positively modulates alterations in markers related to muscle homeostasis.

RESUMO

This paper presents a dataset from a survey of student experiences and perceptions of Emergency Remote Teaching (ERT) during the COVID-19 pandemic in the Munster Technological University, a new higher education institute in the south-west of Ireland formed from the recent merger of two older institutes of technology. Data were collected throughout the month of May 2021 using the online survey tool Typeform with the survey itself being promoted with the student body primarily via email, social media and the university's Learning Management System. There were a total of 1703 responses (approx. 11% response rate which maps to less than a 2.5% margin of error at a 95% level of confidence). The survey was designed to elicit data with respect to student background, workspace and access; ERT tools and platforms used; challenges faced during the ERT period as well as benefits and preferred future teaching and learning modes. The dataset could be of interest to other researchers, policy makers and administrators interested in student experiences of and insight with respect to ERT and student views on the legacy of ERT. Data also provide opportunity to cross-tabulate key variables such as, e.g., internet connectivity and overall ERT experience. Survey questions are also included for replicability purposes. The data article also includes students' responses received in CSV and formatted spreadsheet formats.

RESUMO

Weighted football place-kicking acutely enhances the ball velocity (BV) of subsequent standard football place-kicks. However, there is a dearth of research examining the long-term effects of such interventions, with less evidence in existence among elite athlete cohorts. Therefore, the purpose of this study was to investigate the individual effects of a 4 week, eight-session weighted Gaelic football intervention on BV of standard Gaelic football place-kicks among six elite male Gaelic football goalkeepers. This research design was based on a pre-, mid-, post-, and retention-test design. A linear mixed model analysis was employed, with time and participants as fixed effects, and the number of place-kicks per testing session as a random effect. Post hoc tests revealed significant changes in BV for five of the six participants (p < 0.05), with three participants experiencing significant BV increases from pre-test to post-test (p < 0.05), while no significant differences were found between post-test and retention-test. The remaining three participants experienced no significant BV differences from pre-test to post-test and retention-test. These findings suggest that a weighted football place-kicking intervention can be a time-efficient means of maintaining and enhancing BV and, thus, kick distance, among elite goalkeepers during pre-season and in-season phases.

RESUMO

OBJECTIVE: The metabolic and genetic correlates of circulating insulin-like growth factor-1 (IGF-1) and its main circulating carrier, IGF-1-binding-protein-3 (IGFBP-3), are unclear. METHODS AND RESULTS: We measured serum IGF-1 and IGFBP-3 concentrations in a sample of the Framingham Heart Study (N=3977, aged 40+/-9 years, 46% male) and evaluated their relations to cardiovascular risk factors using multivariable regression. Serum IGF-1 was inversely correlated with age, body mass index, total cholesterol, the presence of diabetes, alcohol consumption, and glomerular filtration rate (all P<0.01), whereas the ratio of IGF-1:IGFBP-3 was lower in women and inversely related to age, triglycerides, high-density lipoprotein cholesterol, systolic blood pressure, and alcohol consumption (all P<0.0001). Circulating IGF-1 correlated negatively with insulin resistance (homeostatic model assessment) (r=-0.1; P<0.0001) and was lower in participants with more components of the metabolic syndrome (Adult Treatment Panel III criteria) (P<0.0001). Additive genetic factors (heritability) accounted for 43% and 39% of the variation of IGF-1 and IGFBP-3, respectively (both P<10(-27)). CONCLUSIONS: Our cross-sectional observations in a large community-based sample link lower circulating IGF-1 to greater metabolic risk burden and underscore substantial genetic influences on IGF-1 concentrations. Prospective studies are warranted to elucidate whether lower IGF-1 concentrations predict greater metabolic risk longitudinally.

RESUMO

BACKGROUND: Certain nutrients have shown protective effects against frailty, but less is known about the influence of individual food groups. Thus, this study aimed to investigate the relationship between the intake of different food groups and physical frailty in a cohort of community-dwelling older adults in Cork, Ireland. METHODS: One hundred and forty-two (n = 81 females, n = 61 males, age 74.1 ± 6.80 years) Irish community-dwelling volunteers aged ⩾65 years participated in this cross-sectional study. Dietary intake was assessed using a validated food frequency questionnaire (FFQ). Frailty was identified as having 3 or more of the following criteria: weight loss, exhaustion, weakness, slow walking speed and low physical activity. Relationships between intakes of food groups and frailty score were determined using Spearman's rank (and partial rank) correlations and ordinal logistic regression analysis. RESULTS: Negative Spearman's rank correlations were observed between frailty score and fish and fish products, fruit and vegetables and nuts and seeds, while positive correlations were found between frailty score and potatoes, fats and oils and sugars, preserves and snacks (P < .05). After adjustment for confounders, partial rank correlations remained statistically significant (P < .05) for all of the above dietary variables, with the exception of nuts and seeds (P > .05). Following ordinal logistic regression, the odds ratios (ORs) (95%CI) for frailty incidence for those in the lowest tertile of food group intake compared to the highest were; 3.04 (1.09-8.85) for fish and fish products, 4.34 (1.54-13.13) for fruit and vegetables, 1.52 (0.58-4.15) for nuts and seeds, 0.54 (0.19-1.51) for potatoes, 0.58 (0.17-1.95) for fats and oils and 0.49 (0.16-1.47) for sugars, preserves and snacks. CONCLUSION: This study suggests that intakes of selected food groups are independently associated with frailty. These findings may hold significant relevance for the development of future frailty prevention strategies.

RESUMO

Research suggests that both nutrition and physical activity can protect mobility in older adults, but it is yet to be determined whether these relationships are affected by gender. Thus, we investigated the gender-specific relationship between nutritional status, physical activity level and functional mobility in Irish older adults. A cross-sectional study was undertaken in 176 community-dwelling older adults (73.6 ± 6.61 years) living in Cork, Ireland. Nutritional status was measured using the Mini Nutritional Assessment-Short Form (MNA-SF) and physical activity was assessed via the Physical Activity Scale for the Elderly (PASE). Functional mobility was measured using the Timed Up and Go (TUG) test. The gender-stratified relationship between variables was assessed using Pearson's correlations and multiple linear regression. Partial correlations (p < 0.05) were observed for TUG with PASE score in both genders, and with MNA-SF score in females, only. Multiple regression showed that physical activity was a predictor of TUG in both genders (ß = 0.257 for males, ß = 0.209 for females, p < 0.05), while nutritional status was a predictor of TUG in females, only (ß = -0.168, p = 0.030). Our results suggest that physical activity is associated with functional mobility in both genders, while the relationship between nutritional status and mobility may be specific to older females. These findings may be of interest for the design of functional preservation strategies.

RESUMO

BACKGROUND AND AIMS: Older adults are a population group at risk of inadequate nutrition due to reduced appetite, malabsorption, taste alterations and social factors. Yet, dietary investigations in Irish older adults are scarce. The aim of this study was to analyse the nutritional status and dietary intake of a sample of community-dwelling Irish elderly, in addition to the effect of age and gender on dietary intake in this age group. METHODS: A cross-sectional study was performed in 162 (n = 91 female, n = 71 male, age 73.8 ± 6.8 years) adults aged 65 years and over in a region of Southern Ireland. Nutritional status was measured using the Mini Nutritional Assessment - Short Form (MNA-SF). Dietary intake was assessed using a semi-quantitative food frequency questionnaire (FFQ). RESULTS: 21.0% and 1.2% of the study population were at risk of malnutrition and malnourished, respectively. A high prevalence of dietary insufficiencies was observed. The most common insufficiencies reported were energy (54.9%), fibre (82.7%), calcium (58.6%), magnesium (62.3%), iron (54.9%), folate (66.0%), vitamin D (93.2%) and vitamin E (61.1%). Increasing age did not significantly influence nutrient intakes in males, while vitamin C and vitamin D intakes decreased with age in females, and the incidence of dietary folate insufficiency was higher in the oldest females. Gender differences in dietary intake were evident, with a higher prevalence of dietary inadequacy in male subjects. Excessive intake of sugars, snacks and fats was observed, particularly in males, while dairy recommendations were not being met. Dietary supplement use was rare (27.2%). CONCLUSIONS: The poor dietary quality of this cohort may have significant health implications. Public health strategies to improve the diets of older adults are warranted, with a particular focus on increasing micronutrient intakes.

RESUMO

A role for vitamin D in the immune system is emerging from human research but data in the bovine is limited. In the current study, 48 Holstein-Friesian calves were randomly assigned to one of 4 groups designed to expose calves to divergent vitamin D levels for a 7 month period and to determine its effects on circulating immunity in young calves. Concentrations of circulating 25-hydroxyvitamin D (25OHD) was measured in serum using a commercial ELISA with validated bovine standards. Results showed that mean circulating concentrations of 25OHD at birth was 7.64 ± 3.21 ng/ml indicating vitamin D deficiency. Neither the injection of Vit D3 at birth nor the elevated levels in milk replacer yield discernible changes to pre-weaning circulating concentration of 25OHD. No calf reached the recommended level of vitamin D immune sufficiencyof 30 ng/ml of 25OHD until at least 3 months of age (T4). Increasing dietary Vit D3 via ration in the post-weaning period significantly elevated 25OHD concentrations in serum in VitD-In calves. Maximal levels of circulating 25OHD were achieved in VitD-Out calves, reaching 60.86 ± 7.32 ng/ml at 5 months of age (T7). Greatest divergence in haematology profile was observed between Ctl-In vs VitD-In groups with Ctl-In calves showing an elevated count of neutrophils, eosinophils, and basophils associated with reduced 25OHD concentrations. Neither IL-8 expression nor ROS production in serum were significantly different between calves with high and low 25OHD, indicating that other vitamin D-dependent mechanisms may contribute to the divergent circulating cellular profiles observed. This novel data on the vitamin D status of neonatal calves identifies a significant window of vitamin D insufficiency which is associated with significant differences in circulating immune cell profiles. Vitamin D insufficiency may therefore exacerbate pre-weaning disease susceptibility, and further work in now warranted.

RESUMO

AIMS: Indacaterol/glycopyrronium (IND/GLY) 110/50 µg is a once-daily (o.d.) fixed-dose combination of long-acting ß2-agonist/long-acting muscarinic antagonist approved in over 90 countries, including Ireland, for the management of COPD. The present study was conducted to evaluate health status of COPD patients, initiated on IND/GLY 110/50 µg o.d., using the Clinical COPD Questionnaire (CCQ) tool in a real-world primary care setting in Ireland. METHODS: This was a real-world, prospective, open-label study. COPD patients aged > 40 years and with a smoking history of > 10 pack-years were included and switched to once-daily IND/GLY 110/50 µg. Enrolment of patients into the study occurred only after the decision had been made by the physician to prescribe IND/GLY 110/50 µg. Data were collected at baseline and Week 26. Health status was assessed using the validated CCQ. RESULTS: A total of 200 patients were included in study. The mean CCQ total score decreased from 2.36 at baseline to 1.44 at Week 26 (Δ, 0.92; P < 0.0005). Of the 156 patients who completed study, 113 (72.4%) achieved minimum clinically important difference in CCQ total score with IND/GLY 110/50 µg. CCQ domain scores also decreased during the study. Improvement in health status was observed across all GOLD groups and irrespective of prior COPD treatment. Adverse events were reported by 20% of patients with COPD exacerbation/infected COPD being the most common AE, reported by 11 patients. CONCLUSIONS: In real-life clinical practice in Ireland, IND/GLY 110/50 µg o.d. demonstrated statistically significant and clinically important improvement in health status in patients with COPD.

RESUMO

PURPOSE: This study aimed to investigate the relationship between fundamental movement skills (FMS) and markers of health among a cohort of Irish primary school children. METHODS: Participants (N = 296, mean age: 7.99 ± 2.02 years) were senior infant (n = 149, mean age: 6.02 ± 0.39 years) and 4th class (n = 147, mean age: 9.97 ± 0.40 years) students from three primary schools in Cork, Ireland. FMS proficiency (TGMD-2) and markers of health (BMI percentile, waist circumference percentile, blood pressure percentiles, resting heart rate, cardiorespiratory fitness, objectively measured physical activity; PA) measurements were recorded. Correlation and hierarchical stepwise multiple linear regression analyses were conducted to investigate the relationship between FMS and markers of health. RESULTS: A small, positive relationship was found between FMS (Gross Motor Quotient; GMQ) and cardiorespiratory fitness with small negative correlations between GMQ and 550 m time SDS among 6-year-olds (r(129) = -.286, p < .05) and 10-year-olds (r(132) = -.340, p < .05). A moderate, positive correlation was found between GMQ and light PA (r(71) = .400, p < .05). Small positive correlations were revealed between GMQ and moderate PA (r(71) = .259, p < .05) and between GMQ and total PA (r(71) = .355, p < .05). After adjusting for age, sex, the interaction effect of age and sex, and school attended, FMS explained 15.9% and 24.8% of the variance in 550 m time SDS among 6- and 10-year-olds, respectively, and 6% and 6.5% of the variance in light PA and moderate PA, respectively. After adjusting for age and sex, FMS explained 11.6% of the variance in total PA. CONCLUSION: A wide range of FMS is important for children's cardiorespiratory fitness and PA.
