Kids active: the development and evaluation of an active play and fundamental movement skill intervention for preschool children

Introduction: Fundamental movement skills (FMS) are basic movement patterns that form the building blocks of physical activity (PA). The preschool years (ages 3-5) represent an important time for the development of FMS and healthy PA behaviours and the childcare setting plays an important role in this. Low levels of PA and FMS have been demonstrated for preschool children internationally, though research in Ireland has not yet focused on this age group. Objectives: The main aim of this study was to design and evaluate an educator-led FMS and PA (through active play) intervention for preschool children in services participating in the Early Childhood Care and Education (ECCE) scheme. Additionally, this study aimed to investigate current levels of PA and FMS of preschool children in this setting during ECCE hours. Methods: The pilot programme was delivered to 42 educators from 18 services. Data were collected by trained researchers from 141 children in 9 preschool services (5 intervention, 4 control) in March 2016 (pre-intervention) and June 2016 (post-intervention). Accelerometry was used to collect PA data and FMS proficiency was measured for four skills using the Test of Gross Motor Development-2 (TGMD-2) (Ulrich, 2000). All educators who received the programme and those from the control group completed the CAN-Teach questionnaire (Derscheid et al, 2014) pre-and post-intervention (n=32) to measure confidence to teach PA. Results: At baseline, boys aged 3 were the most active with 46.9% meeting PA recommendations. Gender and age influenced PA, with boys more active than girls and younger children more active than older. Mastery or near mastery of FMS ranged from 4.9% (throw) to 88.4% (run). Post-intervention, intervention educators achieved significantly higher confidence scores than control educators. All children decreased sedentary behaviour (SB) and increased PA, with the intervention group significantly decreasing SB (-7 minutes) while the control group increased SB (+2.1 minutes) in hour two of the three-hour ECCE day. Children in the intervention group significantly increased scores in the throw compared to control group (increase of 1.3 vs 0.1). Conclusion: Increases in educator confidence highlights the potential for increasing educator confidence to deliver PA and FMS opportunities in ECCE services through training. Although PA changes were small, significant differences in the throw show potential for the Kids Active programme over a longer time frame. Further research, including a qualitative component, is warranted to gain greater understanding of how to influence PA behaviour and FMS development in ECCE

Physical activity recommendations for early childhood: an international analysis of ten different countries’ current national physical activity policies and practices for those under the age of 5

During the last two decades there have been growing interests on recommendations for children’s physical activity. The World Health Organization (WHO) launched the first global international recommendations for children in 2010, focusing on children and youth aged 5-17 year olds. The recommendations were based on the dose-response relationship between the frequency, duration, intensity, type and amount of physical activity needed for prevention of non-communicable diseases. There remains however, at time of writing, (2019) a gap in the recommendations, as the WHO did not offer global recommendations for those children under the age of 5 (early years). An international policy and practice analysis, (not previously undertaken), of ten sample countries, was completed of current national physical activity practices. Also an international comparison of early years’ education settings were examined, specifically for those under the age of 5, to investigate current curricula, as well as the qualifications, knowledge and understanding of those supporting children’s learning in different cultural contexts. The sample of ten countries (Belgium, China, Denmark, Finland, Germany, Ireland, Italy, Norway, United Kingdom and United States of America) questioned whether the global daily physical activity recommendations (WHO, 2010) are costumed and used for to the early years’ age group on a national level or if they need to be adjusted. The analysis revealed that eight countries have developed their own national recommendations for children below the age of 5, while only two countries do not have any early years’ specific physical activity recommendations. National authorities seem to be the most common executive sources behind the recommendations. The content of physical activity for children under the age of 5, mostly included the total amount and intensity of physical activity. The total daily amount of physical activity in these ten countries varies between 60 minutes moderate to vigorous intensity physical activity up to 180 min total light to moderate intensity physical activity and for some countries the daily recommendations are only from age 1 year, not between birth and 1 year, this age range remains unsupported. The conclusions from the analysis of national recommendations, underlined the need to see the global recommendations be developed for the younger age group, to support all countries. It is proposed a need for universally new recommendations to go beyond just physical activity intensity levels and to consider how young children’s development can be supported in a versatile way by physically active play. Also age specific recommendations are offered for appropriate and purposeful physical activity to support early years and school aged children’s overall development. The findings also suggest educational recommendations for staff members of early childhood education and care settings to know appropriate and age specific recommendations to ensure they are able to support young children to reach the national and global recommendations. Research recommendations are also proposed

Highlighting gaps in spinal cord injury research in activity-based interventions for the upper extremity: A scoping review.

BACKGROUND: Upper extremity activity-based therapy for neurologic disorders employs high-intensity, high repetition functional training to exploit neuroplasticity and improve function. Research focused on high-intensity upper extremity activity-based therapy for persons with spinal cord injury (SCI) is limited. OBJECTIVE: To summarize high-intensity activity-based interventions used in neurological disorders for their current or potential application to SCI. METHODS: The scoping review included articles from MEDLINE, CINAHL, Cochrane CENTRAL, and OTseeker with the criteria: non-invasive activity-based interventions delivered atleast three times/week for two weeks, upper extremity functional outcomes, 13 years or older, English language, and neurological disorders three months post onset/injury. RESULTS: The search yielded 172 studies. There were seven studies with SCI, all in adults. Activity-based interventions in SCI included task-specific training and gaming, with and without electrical stimulation, and a robotic exoskeleton. The other populations found in the review included studies in stroke, cerebral palsy, and multiple sclerosis. Thirty-four different interventions were reported in other populations. In comparison to the extensive stroke research, work in SCI was not found for high-intensity interventions using virtual reality, brain stimulation, rehabilitation devices, and applications to the home and telerehab settings. CONCLUSION: The results highlight critical gaps within upper extremity high-intensity activity-based research in SCI

The Malaria Testing and Treatment Market in Kinshasa, Democratic Republic of the Congo, 2013

Background The Democratic Republic of Congo (DRC) is one of the two most leading contributors to the global burden of disease due to malaria. This paper describes the malaria testing and treatment market in the nation’s capital province of Kinshasa, including availability of malaria testing and treatment and relative anti-malarial market share for the public and private sector. Methods A malaria medicine outlet survey was conducted in Kinshasa province in 2013. Stratified multi-staged sampling was used to select areas for the survey. Within sampled areas, all outlets with the potential to sell or distribute anti-malarials in the public and private sector were screened for eligibility. Among outlets with anti-malarials or malaria rapid diagnostic tests (RDT) in stock, a full audit of all available products was conducted. Information collected included product information (e.g. active ingredients, brand name), amount reportedly distributed to patients in the past week, and retail price. Results In total, 3364 outlets were screened for inclusion across Kinshasa and 1118 outlets were eligible for the study. Among all screened outlets in the private sector only about one in ten (12.1%) were stocking quality-assured Artemisinin-based Combination Therapy (ACT) medicines. Among all screened public sector facilities, 24.5% had both confirmatory testing and quality-assured ACT available, and 20.2% had sulfadoxine-pyrimethamine (SP) available for intermittent preventive therapy during pregnancy (IPTp). The private sector distributed the majority of anti-malarials in Kinshasa (96.7%), typically through drug stores (89.1% of the total anti-malarial market). Non-artemisinin therapies were the most commonly distributed anti-malarial (50.1% of the total market), followed by non quality-assured ACT medicines (38.5%). The median price of an adult quality-assured ACT was $6.59, and more expensive than non quality-assured ACT ($3.71) and SP ($0.44). Confirmatory testing was largely not available in the private sector (1.1%). Conclusions While the vast majority of anti-malarial medicines distributed to patients in Kinshasa province are sold within the private sector, availability of malaria testing and appropriate treatment for malaria is alarmingly low. There is a critical need to improve access to confirmatory testing and quality-assured ACT in the private sector. Widespread availability and distribution of non quality-assured ACT and non-artemisinin therapies must be addressed to ensure effective malaria case management

Probing the urea dependence of residual structure in denatured human α-lactalbumin

Backbone 15N relaxation parameters and 15N–1HN residual dipolar couplings (RDCs) have been measured for a variant of human α-lactalbumin (α-LA) in 4, 6, 8 and 10 M urea. In the α-LA variant, the eight cysteine residues in the protein have been replaced by alanines (all-Ala α-LA). This protein is a partially folded molten globule at pH 2 and has been shown previously to unfold in a stepwise non-cooperative manner on the addition of urea. 15N R2 values in some regions of all-Ala α-LA show significant exchange broadening which is reduced as the urea concentration is increased. Experimental RDC data are compared with RDCs predicted from a statistical coil model and with bulkiness, average area buried upon folding and hydrophobicity profiles in order to identify regions of non-random structure. Residues in the regions corresponding to the B, D and C-terminal 310 helices in native α-LA show R2 values and RDC data consistent with some non-random structural propensities even at high urea concentrations. Indeed, for residues 101–106 the residual structure persists in 10 M urea and the RDC data suggest that this might include the formation of a turn-like structure. The data presented here allow a detailed characterization of the non-cooperative unfolding of all-Ala α-LA at higher concentrations of denaturant and complement previous studies which focused on structural features of the molten globule which is populated at lower concentrations of denaturant

Mortality and pulmonary complications in patients undergoing surgery with perioperative SARS-CoV-2 infection: an international cohort study

Background: The impact of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) on postoperative recovery needs to be understood to inform clinical decision making during and after the COVID-19 pandemic. This study reports 30-day mortality and pulmonary complication rates in patients with perioperative SARS-CoV-2 infection. Methods: This international, multicentre, cohort study at 235 hospitals in 24 countries included all patients undergoing surgery who had SARS-CoV-2 infection confirmed within 7 days before or 30 days after surgery. The primary outcome measure was 30-day postoperative mortality and was assessed in all enrolled patients. The main secondary outcome measure was pulmonary complications, defined as pneumonia, acute respiratory distress syndrome, or unexpected postoperative ventilation. Findings: This analysis includes 1128 patients who had surgery between Jan 1 and March 31, 2020, of whom 835 (74·0%) had emergency surgery and 280 (24·8%) had elective surgery. SARS-CoV-2 infection was confirmed preoperatively in 294 (26·1%) patients. 30-day mortality was 23·8% (268 of 1128). Pulmonary complications occurred in 577 (51·2%) of 1128 patients; 30-day mortality in these patients was 38·0% (219 of 577), accounting for 81·7% (219 of 268) of all deaths. In adjusted analyses, 30-day mortality was associated with male sex (odds ratio 1·75 [95% CI 1·28–2·40], p\textless0·0001), age 70 years or older versus younger than 70 years (2·30 [1·65–3·22], p\textless0·0001), American Society of Anesthesiologists grades 3–5 versus grades 1–2 (2·35 [1·57–3·53], p\textless0·0001), malignant versus benign or obstetric diagnosis (1·55 [1·01–2·39], p=0·046), emergency versus elective surgery (1·67 [1·06–2·63], p=0·026), and major versus minor surgery (1·52 [1·01–2·31], p=0·047). Interpretation: Postoperative pulmonary complications occur in half of patients with perioperative SARS-CoV-2 infection and are associated with high mortality. Thresholds for surgery during the COVID-19 pandemic should be higher than during normal practice, particularly in men aged 70 years and older. Consideration should be given for postponing non-urgent procedures and promoting non-operative treatment to delay or avoid the need for surgery.

Using psychological theory and qualitative methods to develop a new evidence-based website about acupuncture for back pain.

INTRODUCTION: Potential acupuncture patients seek out information about acupuncture from various sources including websites, many of which are unreliable. We aimed to create an informative, scientifically accurate and engaging website to educate patients about acupuncture for back pain and modify their beliefs in a way that might enhance its clinical effects. METHODS: We used psychological theory and techniques to design an evidence-based website, incorporating multimedia elements. We conducted qualitative "think aloud" audio-recorded interviews to elicit user views of the website. A convenience sample of ten participants (4 male; aged 21-64 years from the local community) looked at the website in the presence of a researcher and spoke their thoughts out loud. Comments were categorised by topic. RESULTS: The website comprises 11 main pages and addresses key topics of interest to potential acupuncture patients, including beneficial and adverse effects, mechanisms of action, safety, practicalities, and patients' experiences of acupuncture. It provides information through text, evidence summaries and audio-clips of four patients' stories and two acupuncturists' descriptions of their practice, and three short films. Evidence from the think aloud study was used to identify opportunities to make the website more informative, engaging, and user-friendly. CONCLUSIONS: Using a combination of psychological theory and qualitative interviews enabled us to produce a user-friendly, evidence-based website that is likely to change patients' beliefs about acupuncture for back pain. Before using the website in clinical settings it is necessary to test its effects on key outcomes including patients' beliefs and capacity for making informed choices about acupuncture

31st Annual Meeting and Associated Programs of the Society for Immunotherapy of Cancer (SITC 2016) : part two

Background The immunological escape of tumors represents one of the main ob- stacles to the treatment of malignancies. The blockade of PD-1 or CTLA-4 receptors represented a milestone in the history of immunotherapy. However, immune checkpoint inhibitors seem to be effective in specific cohorts of patients. It has been proposed that their efficacy relies on the presence of an immunological response. Thus, we hypothesized that disruption of the PD-L1/PD-1 axis would synergize with our oncolytic vaccine platform PeptiCRAd. Methods We used murine B16OVA in vivo tumor models and flow cytometry analysis to investigate the immunological background. Results First, we found that high-burden B16OVA tumors were refractory to combination immunotherapy. However, with a more aggressive schedule, tumors with a lower burden were more susceptible to the combination of PeptiCRAd and PD-L1 blockade. The therapy signifi- cantly increased the median survival of mice (Fig. 7). Interestingly, the reduced growth of contralaterally injected B16F10 cells sug- gested the presence of a long lasting immunological memory also against non-targeted antigens. Concerning the functional state of tumor infiltrating lymphocytes (TILs), we found that all the immune therapies would enhance the percentage of activated (PD-1pos TIM- 3neg) T lymphocytes and reduce the amount of exhausted (PD-1pos TIM-3pos) cells compared to placebo. As expected, we found that PeptiCRAd monotherapy could increase the number of antigen spe- cific CD8+ T cells compared to other treatments. However, only the combination with PD-L1 blockade could significantly increase the ra- tio between activated and exhausted pentamer positive cells (p= 0.0058), suggesting that by disrupting the PD-1/PD-L1 axis we could decrease the amount of dysfunctional antigen specific T cells. We ob- served that the anatomical location deeply influenced the state of CD4+ and CD8+ T lymphocytes. In fact, TIM-3 expression was in- creased by 2 fold on TILs compared to splenic and lymphoid T cells. In the CD8+ compartment, the expression of PD-1 on the surface seemed to be restricted to the tumor micro-environment, while CD4 + T cells had a high expression of PD-1 also in lymphoid organs. Interestingly, we found that the levels of PD-1 were significantly higher on CD8+ T cells than on CD4+ T cells into the tumor micro- environment (p < 0.0001). Conclusions In conclusion, we demonstrated that the efficacy of immune check- point inhibitors might be strongly enhanced by their combination with cancer vaccines. PeptiCRAd was able to increase the number of antigen-specific T cells and PD-L1 blockade prevented their exhaus- tion, resulting in long-lasting immunological memory and increased median survival
