A systematic evaluation of physical activity and diet policies in Scotland: results from the 2021 Active Healthy Kids Report Card.

BACKGROUND: Policymaking regarding physical activity (PA) and diet plays an important role in childhood health promotion. This study provides a detailed examination of Scottish government and policy for child and adolescent PA and diet and discusses strengths and areas for improvement. METHODS: Scottish policy documents (n = 18 [PA]; n = 10 [diet])-published in 2011-20-were reviewed for grading using an adapted version of the Health-Enhancing Physical Activity Policy Audit Tool Version 2. RESULTS: There is clear evidence of leadership and commitment to improving PA and diet and tackling obesity in children and adolescents. The allocation of funds and resources for policy implementation has increased substantially over the past decade. Progress through early key stages of public policymaking-policy agenda and formation-has improved. However, there is limited information on later key stages, including policy monitoring and evaluation. CONCLUSIONS: Childhood PA and diet are a clear priority in Scotland, and PA and diet policies clearly support the desire to achieve other goals, including reducing inequalities and increasing active travel in Scotland. Nonetheless, future policies should be further strengthened through clear(er) plans of implementation, and monitoring and evaluation to support their societal impact.

Relative resistance of Salmonella serotypes (Typhimurium, Infantis, and Reading) to peroxyacetic acid on chicken wings.

Peroxyacetic acid (PAA) is widely used as an antimicrobial in poultry processing. Recent salmonellosis outbreaks caused by Salmonella Infantis (SI) from chicken products and Salmonella Reading (SR) from turkey products have raised concerns about their enhanced resistance (compared to Salmonella Typhimurium [ST]) to commonly used antimicrobial interventions such as PAA. The objective of this research was to evaluate the efficacy of PAA against Salmonella serotypes (Typhimurium, Infantis and Reading), effect on product color and decomposition of PAA at different pH levels. Fresh chicken wings (0.45 kg) were inoculated with a cocktail (ca. 6 log CFU/mL) of nalidixic acid resistant ST, rifampicin resistant SI and kanamycin resistant SR. Inoculated chicken wings were immersed in PAA solutions (100 or 500 ppm; adjusted to either pH 8.5 or unadjusted natural pH) for either 10 s or 60 min to replicate treatments for chicken parts or whole carcasses, respectively. Treated chicken wings were rinsed in buffered peptone water (100 mL) containing sodium thiosulfate (0.1 %), serially diluted in peptone water supplemented with 200 ppm of nalidixic acid, rifampicin or kanamycin for enumeration of ST, SI, and SR respectively, and plated on APC Petrifilm. Immersion of chicken wings in 500 ppm PAA for 60 min resulted in greater microbial reductions (P ≤ 0.05) of ST, SI, SR of ca. Two log CFU/mL each, compared to 10 s treatment. Regardless of concentration and pH of PAA, increased exposure time (60 min vs. 10 s) resulted in greater reductions (P ≤ 0.05) of ST, SI, SR. ST was slightly more resistant to PAA solutions than S. Infantis and S. Reading (P ≤ 0.05) for all experimental conditions (PAA conc, pH, and exposure times). Faster decomposition of PAA (100 and 500 ppm) was observed at pH 8.5 compared to unadjusted, natural pH (P ≤ 0.05). Product color (lightness, L*) was not affected regardless of the PAA concentration, exposure time or the pH.

Nerve ultrasound in Friedreich's Ataxia: enlarged nerves as a biomarker of disease severity.

OBJECTIVE: In Friedreich's ataxia research, the focus is on discovering treatments and biomarkers to assess disease severity and treatment effects. Our study examines high-resolution nerve ultrasound in these patients, seeking correlations with established clinical markers of disease severity. METHOD: Ten patients with Friedreich's Ataxia underwent a comprehensive clinical assessment with established scales (SARA, FARS, mFARS, INCAT, ADL 0-36, IADL). Additionally, they underwent nerve conduction studies and high-resolution nerve ultrasound. Quantitative evaluation of nerve cross-sectional area, conducted at 24 nerve sites using high-resolution nerve ultrasound, was compared with data obtained from 20 healthy volunteers. RESULTS: All the patients had a severe sensory axonal neuropathy. High-resolution nerve ultrasound showed significant increase, in cross sectional area, of median and ulnar nerves at the axilla and arm. The cumulative count of affected nerve sites was directly associated with clinical disability, as determined by SARA, FARS, mFARS, ADL 0-36, and INCAT score, while displaying an inverse correlation with IADL. CONCLUSIONS: Our study shows that high-resolution ultrasound reveals notable nerve abnormalities, primarily in the upper limbs of patients diagnosed with Friedreich's Ataxia. The observed correlation between these nerve abnormalities and clinical disability scales indicates the potential use of this technique as a biomarker for evaluating disease severity and treatment effects. SIGNIFICANCE: Nerve Ultrasound is a potential biomarker of disease severity in Friedreich's Ataxia.

Predicting value for incomplete recovery in Bell's palsy of facial nerve ultrasound versus nerve conduction study.

OBJECTIVE: This longitudinal study aims at assessing the predictive value of facial nerve high-resolution ultrasound (HRUS) for incomplete clinical recovery in patients with Bell's palsy, the most common facial nerve disease. METHODS: We prospectively enrolled 34 consecutive patients with Bell's palsy. All patients underwent neurophysiological testing (including facial nerve conduction study) and HRUS evaluations 10-15 days (T1), one month (T2), and three months (T3) after the onset of Bell's palsy. Patients who did not experience complete recovery within three months were also evaluated after six months (T4). We have then compared the accuracy of HRUS with that of the facial nerve conduction study in predicting incomplete clinical recovery at three and six months. RESULTS: At T1, the facial nerve diameter, as assessed with HRUS, was larger on the affected side than on the normal side, particularly in patients with incomplete recovery at T2, T3 and T4. ROC curve analysis, however, showed that the facial nerve diameter at T1 had a lower predictive value than the facial nerve conduction study for an incomplete clinical recovery at three (T3) and six (T4) months. Still, the facial nerve diameter asymmetry, as assessed with HRUS, had a relatively high negative predictive value (thus indicating a strong association between normal HRUS examination and a good prognosis). CONCLUSIONS: Although HRUS shows abnormally increased facial nerve diameter in patients in the acute phase of Bell's palsy, the predictive value of this technique for incomplete clinical recovery at three and six months is lower than that of the nerve conduction study. SIGNIFICANCE: Nerve ultrasound has a low predictive value for incomplete clinical recovery in patients with Bell's Palsy.

Application of continuous positive airway pressure in the delivery room: a multicenter randomized clinical trial

This study evaluated whether the use of continuous positive airway pressure (CPAP) in the delivery room alters the need for mechanical ventilation and surfactant during the first 5 days of life and modifies the incidence of respiratory morbidity and mortality during the hospital stay. The study was a multicenter randomized clinical trial conducted in five public university hospitals in Brazil, from June 2008 to December 2009. Participants were 197 infants with birth weight of 1000-1500 g and without major birth defects. They were treated according to the guidelines of the American Academy of Pediatrics (APP). Infants not intubated or extubated less than 15 min after birth were randomized for two treatments, routine or CPAP, and were followed until hospital discharge. The routine (n=99) and CPAP (n=98) infants studied presented no statistically significant differences regarding birth characteristics, complications during the prenatal period, the need for mechanical ventilation during the first 5 days of life (19.2 vs 23.4%, P=0.50), use of surfactant (18.2 vs 17.3% P=0.92), or respiratory morbidity and mortality until discharge. The CPAP group required a greater number of doses of surfactant (1.5 vs 1.0, P=0.02). When CPAP was applied to the routine group, it was installed within a median time of 30 min. We found that CPAP applied less than 15 min after birth was not able to reduce the need for ventilator support and was associated with a higher number of doses of surfactant when compared to CPAP applied as clinically indicated within a median time of 30 min.

Semi-automatic measurement of visual verticality perception in humans reveals a new category of visual field dependency

Previous assessment of verticality by means of rod and rod and frame tests indicated that human subjects can be more (field dependent) or less (field independent) influenced by a frame placed around a tilted rod. In the present study we propose a new approach to these tests. The judgment of visual verticality (rod test) was evaluated in 50 young subjects (28 males, ranging in age from 20 to 27 years) by randomly projecting a luminous rod tilted between -18 and +18° (negative values indicating left tilts) onto a tangent screen. In the rod and frame test the rod was displayed within a luminous fixed frame tilted at +18 or -18°. Subjects were instructed to verbally indicate the rod’s inclination direction (forced choice). Visual dependency was estimated by means of a Visual Index calculated from rod and rod and frame test values. Based on this index, volunteers were classified as field dependent, intermediate and field independent. A fourth category was created within the field-independent subjects for whom the amount of correct guesses in the rod and frame test exceeded that of the rod test, thus indicating improved performance when a surrounding frame was present. In conclusion, the combined use of subjective visual vertical and the rod and frame test provides a specific and reliable form of evaluation of verticality in healthy subjects and might be of use to probe changes in brain function after central or peripheral lesions.

Effect of postnatal malnutrition on hyperoxia-induced newborn lung development

Several factors are associated with bronchopulmonary dysplasia. Among them, hyperoxia and lung immaturity are considered to be fundamental; however, the effect of malnutrition is unknown. Our objective was to evaluate the effects of 7 days of postnatal malnutrition and hyperoxia on lung weight, volume, water content, and pulmonary morphometry of premature rabbits. After csection, 28-day-old New Zealand white rabbits were randomized into four groups: control diet and room air (CA, N = 17), control diet and ¡Ý95% O2 (CH, N = 17), malnutrition and room air (MA, N = 18), and malnutrition and ¡Ý95% O2 (MH, N = 18). Malnutrition was defined as a 30% reduction of all the nutrients provided in the control diet. Treatments were maintained for 7 days, after which histological and morphometric analyses were conducted. Lung slices were stained with hematoxylin-eosin, modified orcein-resorcin or picrosirius. The results of morphometric analysis indicated that postnatal malnutrition decreased lung weight (CA: 0.83 ¡À 0.19; CH: 0.96 ¡À 0.28; MA: 0.65 ¡À 0.17; MH: 0.79 ¡À 0.22 g) and water content, as well as the number of alveoli (CA: 12.43 ¡À 3.07; CH: 8.85 ¡À 1.46; MA: 7.33 ¡À 0.88; MH: 6.36 ¡À 1.53 x 10-3/mm) and elastic and collagen fibers. Hyperoxia reduced the number of alveoli and increased septal thickening and the mean linear intercept. The reduction of alveolar number, collagen and elastic fibers was intensified when malnutrition and hyperoxia were associated. These data suggest that dietary restriction enhances the magnitude of hyperoxia-induced alveolar growth arrest and lung parenchymal remodeling. It is interesting to consider the important influence of postnatal nutrition upon lung development and ronchopulmonary dysplasia.

Risk factors associated with the death of patients hospitalized for juvenile systemic lupus erythematosus

We assessed the risk factors associated with death in patients hospitalized for juvenile systemic lupus erythematosus (JSLE) and evaluated the autopsy reports. A total of 57,159 hospitalizations occurred in our institution from 1994 to 2003, 169 of them involving 71 patients with JSLE. The most recent hospitalization of these patients was evaluated. Patients were divided into two groups based on mortality during hospitalization: those who survived (N = 53) and those who died (N = 18). The main causes of hospitalization were JSLE activity associated with infection in 52 percent and isolated JSLE activity in 44 percent. Univariate analysis showed that a greater risk of death was due to severe sepsis (OR = 17.8, CI = 4.5-70.9), systemic lupus erythematosus disease activity index (SLEDAI) ³8 (OR = 7.6, CI = 1.1-53.8), general infections (OR = 6.1, CI = 1.5-25), fungal infections (OR = 5.4, CI = 3.2-9), acute renal failure (OR = 5.1, CI = 2.5-10.4), acute thrombocytopenia (OR = 3.9, CI = 1.9-8.4), and bacterial infections (OR = 2.3, CI = 1.2-7.5). Stratified analysis showed that severe sepsis and SLEDAI ³8 were not confounder variables. In the multivariate analysis, logistic regression showed that the only independent variable in death prediction was severe sepsis (OR = 98, CI = 16.3-586.2). Discordance between clinical diagnosis and autopsy was observed in 6/10 cases. Mortality of hospitalized JSLE patients was associated with severe sepsis. Autopsy was important to determine events not detected or doubtful in dead patients and should always be requested.

Prevalence of asthma, rhinitis and eczema in 6 - 7 years old students from the western districts of São Paulo City, using the standardized questionnaire of the "International Study of Asthma and Allergies in Childhood" (ISAAC)-phase IIIB

The aims of the present work were the evaluation of allergic disease prevalence among 6 and 7 year-old students from the western districts of São Paulo city and the comparison of these data with those obtained in the International Study of Asthma and Allergies in Childhood (ISAAC) phase I, performed in the central-southern districts of São Paulo, using the ISAAC standardized written questionnaire. METHODS: 5,040 questionnaires were distributed and 3,312 were returned. Proportional differences were estimated by Chi square or Fisher exact tests. Odds Ratio and 95 percent confidence intervals between genders and allergic diseases were calculated. Values of p<0.05 were considered statistically significant. RESULTS: The corrected prevalences found were: asthma 24.4 percent, medical diagnosis of asthma 5.7 percent, rhinitis 25.7 percent, rhinoconjunctivitis 11.3 percent, medical diagnosis of rhinitis 20.0 percent, atopic eczema 9.2 percent. Significant associations between asthma and rhinitis (OR=3.3), asthma and eczema (OR=2.2), and rhinitis and eczema (OR=2.8) occurred. The male gender was prevalent regarding asthma and rhinitis. Compared to data from ISAAC phase I, higher asthma prevalence and severity, and lower values for rhinitis and eczema were observed in this study. CONCLUSIONS: The present study evidenced high prevalences for asthma and rhinitis compared to the children's medical diagnosis. The male gender predominated in all positive responses regarding asthma and rhinitis. The most frequent associations observed were between asthma and rhinitis and asthma and eczema. In the western districts of São Paulo, a higher prevalence of asthma symptoms and severity and lower prevalences for rhinitis and eczema occurred compared to the central-southern districts of the city.

Houve associação significativa entre asma e rinite (OR=3,3), asma e eczema (OR=2,2) e rinite e eczema atópico (OR=2,8). O sexo masculino foi predominante para asma e rinite. Comparando-se os dados da fase I, observou-se prevalência mais elevada dos sintomas e gravidade de asma e valores menores para rinite e eczema. CONCLUSÕES: As prevalências de asma e rinite neste estudo mostraram valores elevados em comparação ao diagnóstico médico. Houve predomínio do sexo masculino para asma e rinite. As associações mais freqüentes foram entre asma e rinite e asma e eczema. Em relação à região centro-sul de São Paulo, observou-se que na região oeste houve maior prevalência dos sintomas e gravidade da asma e menor prevalência de rinite e eczema.

Seizure recurrence in infants with neonatal convulsions: a follow-up study

Vinte e três crianças com crises convulsivas neonatais foram seguidas, prospectivamente, até idade em média de 11 meses. O peso ao nascimento variou de 1700 a 4230 gramas; 2 eram prê-termo; 17 eram meninos e 6, meninas. A encefalopatia hipóxico-siquênica foi a etiologia mais frequente (82,6%. Houve predomínio das crises clônicas focais, presentes em 7/16 crianças nas quais o tipo de crise foi identificado. Todas as crianças foram submetidas a exame neurológico e avaliaçäo eletrencefalográfia e, em 18 delas, foi realizado exame ultrassonográfico (US) de crânio durante o seguimento ambulatorial. A medicaçäo anticonvulsivante foi interrompida se o EEG e o exame neurológico eram normais no seguimento. A recorrência de crises foi observada em 7/23 crianças (30%). Houve relaçäo estatisticamente significante entre a recorrência de crises e anormalidades do exame neurológico, EEG e US de crânio. Concluimos que as crianças com crises convulsivas neonatais podem permanecer sem medicaçäo anticonvulsivante desde que näo apresentem anormalidades ao exame neurológico, ao EEG e ao US de crânio

Sindrome da brida amniotica / Amniotic band syndrome

Os autores descrevem um caso de sindrome da brida amniotica com comprometimento facial, cranial e pe torto congenito. As manifestacoes clinicas principais e a etiologia da sindrome sao discutidas, ressaltando o cuidado com o amniocentese no primeiro trimestre. A sindrome da brida amniotica (S.B.A.) tem varias sinonimias: constricao anular congenita, bandas amniogenicas, banda de tecido aberrante "adam complex" ("amniotic deformaty, adhesions, mutilations") e sequencia da brida amniotica. Ela e constituida por uma serie de anomalias anatomicas do recem-nascido, associadas a estrangulamento de partes feitas "in utero" levando a deformacoes, malformacoes ou roturas. A apresentacao deste caso clinico tem o objetivo de alertar os pediatras e obstetras para esta patologia pouco frequente e cujo diagnostico e muitas vezes feito erroneamente, em vista das multiplas caracteristicas que a sindrome da brida amniotica pode assumir.

Bloqueio átrio-ventricular congênito: características neonatais e evoluçäo / Congenital complete heart block

Säo apresentados 9 casos de RN portadores de bloqueio átrio-ventricular congênito (BAVC) com detecçäo da anomalia no terceiro trimestre de gestaçäo através de ecocardiografia fetal. Todos os RNs foram de termo ou limítrofes e a maioria nasceu de parto cesáreo, em boas condiçöes. Imediatamente após o nascimento, foi realizado avaliaçäo cardiológica completa, através de exame clínico, ECG, Rx de tórax, ecocardiografia e monitorizaçäo de FC pelo Holter contínuo de 24 horas. Cinco RNs apresentaram BAVC com FC basal ao redor de 60 bat/min e, em destes, a sorologia para LES (anti SS-AA/Rô) foi positiva. Os 5 evoluiram bem, tendo recebido alta antes do primeiro mês de vida sem medicaçäo e com acompanhamento ambulatorial. Um RN apresentou BAVC com FC basal ao redor de 50 bat/min, tendo evoluido para ICC ao final do primeiro mês, compensada com o uso de digitálico e diurético. Três casos eram associados com cardiopatia congênita complexa, sendo 2 do tipo átrio-ventricular communis (AVC) e um do tipo transposiçäo corrigida dos grandes vasos da base. Os 2 casos com AVC foram os únicos que descompensaram precocemente (primeira semana de vida). Estes casos mostram que a detecçäo precoce de alteraçöes de ritmo cardíaco no pré-natal, um preparo adequado para a recepçäo do RN ao nascimento, avaliaçäo cardiológica completa, säo fatores decisivos para uma boa evoluçäo pós-natal
