Analytical Assessment and Nutritional Adequacy of School Lunches in Sintra’s Public Primary Schools

School meals present several cost benefits overtime at the short, medium, and long term for individuals and society. This cross-sectional study aims to analyse the nutritional composition and evaluate the adequacy of school lunches. One hundred and fifty-eight samples were collected and analysed from 10 primary schools in Sintra’s municipality, served during one week. On average, energy (27.7% daily energetic requirements) and carbohydrate (48.1%) contents did not reach the reference values, and the content of protein (19.5%) exceeded the reference value (p < 0.05). The mean total fat (28.8%) and saturated fatty acids (5.4%) content complied with the recommendations. The mean salt (1.7 g) and dietary fibre (8.3 g) content exceeded the reference value but did not differ significantly from the recommendations. Addressing school canteens is crucial, not only in a nutritional approach, but also as an opportunity to achieve healthier, sustainable, and accessible food systems, aligned with the Sustainable Development Goals 2030. We highlighted the importance of evaluating evidence-based practices and disseminated practice-based evidence regarding the adequacy of school lunches.     

Machine learning and national health data to improve evidence: Finding segmentation in individuals without private insurance

ObjectiveIndividuals without private health insurance have less access to healthcare, therefore are more prone to experience poor health when compared to those who have. Segmentation is an approach to find homogenous groups of people with the purpose of tailoring services and products. In public policy, segmentation might be used to identify characteristics and needs of specific groups and deliver targeted programs and spare costs. We aim to identify and describe segments within the uninsured population to aid targeted policy actions and improve health.MethodsWe used secondary data collected from a representative, nationwide health survey (n=18,204). For the purpose of our analysis, we included data from individuals who answered “no” to the question: “Do you have private health insurance?” (n=12,134). Variables pertaining information on socio-demographic, health status, access and care were used. A multiple correspondence analysis was performed to find principal components followed by a hierarchical cluster.ResultsWe found three clusters. The first (54.12% of our sample) composed by a group of young, middle aged and professionally active individuals without health problems. The second (36.70%), a cluster of aging individuals composed especially by elderly women, either retired or fulfilling domestic tasks, with a long-term health problem. The last (9.17%) composed by elder people, with long-term health problem and scoring low in mental health related questions.ConclusionOur study found three clusters (profiles of individuals) among the uninsured. Ultimately, our findings aim to support policy makers to deliver customized actions to improve health and provide cost-effective policies.     

Puumala Virus Infection in Family,Switzerland

We report 3 cases of Puumala virus infection in a family in Switzerland in January 2019. Clinical manifestations of the infection ranged from mild influenza-like illness to fatal disease. This cluster illustrates the wide range of clinical manifestations of Old World hantavirus infections and the challenge of diagnosing travel-related hemorrhagic fevers.

Racial differences in selection of ideal body size by adolescent females

Cultural differences may partially account for the fact that more black women than white women are overweight in the United States. This study measured perceptions of ideal body size among 93 black and 80 white females, 14-17 years old, who were randomly selected from three public high schools in a southeastern state. The subjects' height and weight were measured along with their estimates of their mother's body size, weight control attitudes, and demographic variables. Blacks preferred a significantly larger body size than whites when asked to select ideal body size (p = 0.045). Subjects who estimated their mother's size to be larger, also selected a larger ideal body size (p = .047). Those who perceived themselves as too fat were more likely to skip meals to help control their weight, compared with those who perceived themselves as normal or too thin (p = .003). Approximately 30% of the sample was overweight or obese. There were not significant racial differences in weight or BMI. These results suggest that overweight is more acceptable among black females than among white females and may help explain why more black females are obese.     

Ascaris–Trichuris association and malnutrition in Brazilian children

This work was designed to evaluate the role of intestinal parasites on nutritional status in three rural areas of Brazil. A total of 520 children aged 1–12 years were studied through a questionnaire concerning housing, socio-economic conditions and a 24-h food intake recall. Measurements of weight and height were also performed, and three stool samples were collected on consecutive days for parasitological analysis. Scores of the standard deviation (z-scores) for the weight-for-height and height-for-age were used to characterise the growth profile. A high prevalence of intestinal parasites was detected, with Giardia lamblia (44%), Endolimax nana (43%), Ascaris lumbricoides (41%) and Trichuris trichiura (40%) being the most prevalent. Eleven per cent of the children were classified as showing stunting. Inadequate daily caloric intake was observed in 78% of the population and the proportion of those with inadequate protein intake was 34%. Logistic regression analysis was employed for the multivariate study. Stunting was significantly associated with estimators of low economic income, inadequate protein intake and polyparasitism, especially the association between Ascaris lumbricoides and Trichuris trichiura .     

Aids in diagnosis of suspect ectopic ureters in female patients

When suspected ectopic ureters cannot be visualized by conventional methods, such as excretory urogram, nephrotomograms, or by intravenous indigo carmine, then direct injection of vaginal, suburethral, or paraurethral "swellings," which are in effect dilated terminal ureters, may confirm the diagnosis.     

Induction of differentiation in human rhabdomyosarcomas

The effectiveness of all presently employed cancer therapies is limited by tumour cell heterogeneity. In patients with rhabdomyosarcomas (RMS), differentiation seemed to be associated with poor prognosis and vice versa. In order to confirm the validity of this observation, we have developed in vitro and in vivo models of RMS wherein the degree of tumour cell differentiation could be manipulated. On subcutaneous implantation in nude mice, 4 of 8 alveolar rhabdomyosarcomas (A-RMS), produced tumours. In 3 of these 4 tumours the N- myc gene was amplified. In contrast, 2 embryonal (E-RMS) lacked N-myc amplification and also failed to grow in nude mice. Two cell lines from E-RMS formed tumours in nude mice. In vitro, a reduction in bovine serum concentration or supplementation of the medium with horse serum induced marked differentiation in an A-RMS but not in an E-RMS. In vivo, subcutaneous xenografts of undifferentiated A-RMS could be induced to differentiate by intratumoural injection of horse serum or transplantation into the peritoneal cavity of rats. This dramatic degree of differentiation was detected by histology and immunocytochemical staining using 3 different markers, viz, desmin, vimentin and myoglobin. Somewhat remarkably, when these differentiated A-RMS growing in the peritoneal cavities of rats, were reinplanted into peritoneal cavities of other rats they failed to grow. On the other hand, if they were reimplanted subcutaneously in other rats they grew well and reverted to an undifferentiated morphology. In contrast, the E-RMS could not be induced to undergo differentiation by horse serum and also failed to grow in the peritoneal cavity of rats.     

Validity and reliability of three generic outcome measures for hand disorders

This is an assessment of three different outcome measures for the hand: the Hand Clinic Questionnaire (HCQ); the Patient Evaluation Measure (PEM); and the Hand Outcome Survey Sheet (HOSS). Each measure has been tested for its reliability and validity. The results suggest that the PEM and the HCQ are comparably consistent but the PEM is more reproducible. Both the PEM and HOSS are valid questionnaires. The PEM is suitable for use in an outpatient clinic and as a postal questionnaire. The HOSS may be used for research or audit especially when the injury has been measured using the Hand Injury Severity Score.
