Improving Students’ Learning Aspirations Beyond Post-Primary Education: A First Account of Two Non-Formal Education Programmes in Middle-Income

Non-formal education programmes are active in a number of developing countries. These programmes offer vulnerable students an opportunity to pursue their education although they were excluded for various reasons from the formal education systems. This paper examines the impact of two programmes (one in Mauritius, and one in Thailand) on their participants’ aspirations towards learning. We develop a methodology to measure the perception of students regarding their learning experience. More than a third of them, for example, believe that there is no barrier to their education. Most acknowledge the role of their teachers in raising their aspirations towards their educational achievement. When compared to male students, female students seem to value more the role of their education.

Intervention précoce dans les troubles psychotiques: quel rôle pour les praticiens de premier recours [Early intervention in psychotic disorders: which role for primary care practitioners?]

The development of early intervention in psychotic disorders has allowed a more optimistic approach and the development of more adapted and more efficient treatments. Primary care practitioners are often the first professional contact for patients developing psychosis, but diagnostic difficulties and patients' reluctance to engage in treatment are often an obstacle to private practice treatment. It is therefore important to provide more information to primary care practitioners on specific characteristics of these disorders and about locally available treatment structures in order to allow them to suspect this relatively rare diagnosis, facilitate the collaboration with flexible and accessible specialist services, that ideally should provide home treatment, and to improve prognosis.

ADOS: an educational primary prevention programme for preventing excess body weight in adolescents.

OBJECTIVE: The prevalence of adolescent obesity has increased considerably over the past decade in Switzerland and has become a serious public health problem in Europe. Prevention of obesity using various comprehensive programmes appears to be very promising, although we must admit that several interventions had generally disappointing results compared with the objectives and target initially fixed. Holistic programmes including nutritional education combined with promotion of physical activity and behaviour modification constitute the key factors in the prevention of childhood and adolescent obesity. The purpose of this programme was to incorporate nutrition/physical education as well as psychological aspects in selected secondary schools (9th grade, 14-17 years). METHODS: The educational strategy was based on the development of a series of 13 practical workshops covering wide areas such as physical inactivity, body composition, sugar, energy density, invisible lipids, how to read food labels, is meal duration important? Do you eat with pleasure or not? Do you eat because you are hungry? Emotional eating. For teachers continuing education, a basic highly illustrated guide was developed as a companion booklet to the workshops. These materials were first validated by biology, physical education, dietician and psychologist teachers as well as school medical officers. RESULTS: Teachers considered the practical educational materials innovative and useful, motivational and easy to understand. Up to now (early 2008), the programme has been implemented in 50 classes or more from schools originating from three areas in the French part of Switzerland. Based on the 1-week pedometer value assessed before and after the 1 school-year programme, an initial evaluation indicated that overall physical placidity was significantly decreased as evidenced by a significant rise in the number of steps per day. CONCLUSION: Future evaluation will provide more information on the effectiveness of the ADOS programme.

Changing Eating Habits - A Field Experiment in Primary Schools

We conduct a field experiment in 31 primary schools in England to test whether incentives to eat fruit and vegetables help children develop healthier habits. The intervention consists of rewarding children with stickers and little gifts for a period of four weeks for choosing a portion of fruit and vegetables at lunch. We compare the effects of two incentive schemes (competition and piece rate) on choices and consumption over the course of the intervention as well as once the incentives are removed and six months later. We find that the intervention had positive effects, but the effects vary substantially according to age and gender. However, we find little evidence of sustained long term effects, except for the children from poorer socio‐economic backgrounds.

Patient and physician gender concordance in preventive care in university primary care settings.

OBJECTIVE: To assess the quality of preventive care according to physician and patient gender in a country with universal health care coverage. METHODS: We assessed a retrospective cohort study of 1001 randomly selected patients aged 50-80years followed over 2years (2005-2006) in 4 Swiss university primary care settings (Basel, Geneva, Lausanne, Zürich). We used indicators derived from RAND's Quality Assessment Tools and examined percentages of recommended preventive care. Results were adjusted using hierarchical multivariate logistic regression models. RESULTS: 1001 patients (44% women) were followed by 189 physicians (52% women). Female patients received less preventive care than male patients (65.2% vs. 72.1%, p<0.001). Female physicians provided significantly more preventive care than male physicians (p=0.01) to both female (66.7% vs. 63.6%) and male patients (73.4% vs. 70.7%). After multivariate adjustment, differences according to physician (p=0.02) and patient gender (p<0.001) remained statistically significant. Female physicians provided more recommended cancer screening than male physicians (78.4 vs. 71.9%, p=0.01). CONCLUSIONS: In Swiss university primary care settings, female patients receive less preventive care than male patients, with female physicians providing more preventive care than male physicians. Greater attention should be paid to female patients in preventive care and to why female physicians tend to provide better preventive care.

Older persons' perceptions of general practitioner or specialist primary care physicians : same point of view?

BACKGROUND: Identification of a Primary Care Physician (PCP) by older patients is considered as essential for the coordination of care, but the extent to which identified PCPs are general practitioners or specialists is unknown. This study described older patients' experiences with their PCP and tested the hypothesis of differences between patients who identify a specialist as their PCP (SP PCP) and those who turn to a general practitioner (GP PCP). METHODS: In 2012, a cross-sectional postal survey on care was conducted in the 68+ year old population of the canton of Vaud. Data was provided by 2,276 participants in the ongoing Lausanne cohort 65+ (Lc65+), a study of those born between 1934 and 1943, and by 998 persons from an additional sample drawn to include the population outside of Lausanne or born before 1934. RESULTS: Participants expressed favourable perceptions, at rates exceeding 75% for most items. However, only 38% to 51% responded positively for out-of-hours availability, easy access and at home visits, likelihood of prescribing expensive medication if needed, and doctors' awareness of over-the-counter drugs. 12.0% had an SP PCP, in 95.9% specialised in a discipline implying training in internal medicine. Bivariate and multivariate analyses did not result in significant differences between GP and SP PCPs regarding perceptions of accessibility/availability, doctor-patient relationship, information and continuity of care, prevention, spontaneous use of the emergency department or ambulatory care utilisation. CONCLUSIONS: Experiences of old patients were mostly positive despite some lack in reported hearing, memory testing, and colorectal cancer screening. We found no differences between GP and SP PCP groups.

Primary Commodity Prices: Co-movements, Common Factors and Fundamentals

The behavior of commodities is critical for developing and developed countries alike. This paper contributes to the empirical evidence on the co-movement and determinants of commodity prices. Using nonstationary panel methods, we document a statistically significant degree of co-movement due to a common factor. Within a Factor Augmented VAR approach, real interest rate and uncertainty, as postulated by a simple asset pricing model, are both found to be negatively related to this common factor. This evidence is robust to the inclusion of demand and supply shocks, which both positively impact on the co-movement of commodity prices.

Detecting and measuring deprivation in primary care: development, reliability and validity of a self-reported questionnaire: the DiPCare-Q.

OBJECTIVES: Advances in biopsychosocial science have underlined the importance of taking social history and life course perspective into consideration in primary care. For both clinical and research purposes, this study aims to develop and validate a standardised instrument measuring both material and social deprivation at an individual level. METHODS: We identified relevant potential questions regarding deprivation using a systematic review, structured interviews, focus group interviews and a think-aloud approach. Item response theory analysis was then used to reduce the length of the 38-item questionnaire and derive the deprivation in primary care questionnaire (DiPCare-Q) index using data obtained from a random sample of 200 patients during their planned visits to an ambulatory general internal medicine clinic. Patients completed the questionnaire a second time over the phone 3 days later to enable us to assess reliability. Content validity of the DiPCare-Q was then assessed by 17 general practitioners. Psychometric properties and validity of the final instrument were investigated in a second set of patients. The DiPCare-Q was administered to a random sample of 1898 patients attending one of 47 different private primary care practices in western Switzerland along with questions on subjective social status, education, source of income, welfare status and subjective poverty. RESULTS: Deprivation was defined in three distinct dimensions: material (eight items), social (five items) and health deprivation (three items). Item consistency was high in both the derivation (Kuder-Richardson Formula 20 (KR20) =0.827) and the validation set (KR20 =0.778). The DiPCare-Q index was reliable (interclass correlation coefficients=0.847) and was correlated to subjective social status (r(s)=-0.539). CONCLUSION: The DiPCare-Q is a rapid, reliable and validated instrument that may prove useful for measuring both material and social deprivation in primary care.

Primary pineal tumors: outcome and prognostic factors-a study from the Rare Cancer Network (RCN).

PURPOSE: To better define outcome and prognostic factors in primary pineal tumors. MATERIALS AND METHODS: Thirty-five consecutive patients from seven academic centers of the Rare Cancer Network diagnosed between 1988 and 2006 were included. Median age was 36 years. Surgical resection consisted of biopsy in 12 cases and resection in 21 (2 cases with unknown resection). All patients underwent radiotherapy and 12 patients received also chemotherapy. RESULTS: Histological subtypes were pineoblastoma (PNB) in 21 patients, pineocytoma (PC) in 8 patients and pineocytoma with intermediate differentiation in 6 patients. Six patients with PNB had evidence of spinal seeding. Fifteen patients relapsed (14 PNB and 1 PC) with PNB cases at higher risk (p = 0.031). Median survival time was not reached. Median disease-free survival was 82 months (CI 50 % 28-275). In univariate analysis, age younger than 36 years was an unfavorable prognostic factor (p = 0.003). Patients with metastases at diagnosis had poorer survival (p = 0.048). Late side effects related to radiotherapy were dementia, leukoencephalopathy or memory loss in seven cases, occipital ischemia in one, and grade 3 seizures in two cases. Side effects related to chemotherapy were grade 3-4 leucopenia in five cases, grade 4 thrombocytopenia in three cases, grade 2 anemia in two cases, grade 4 pancytopenia in one case, grade 4 vomiting in one case and renal failure in one case. CONCLUSIONS: Age and dissemination at diagnosis influenced survival in our series. The prevalence of chronic toxicity suggests that new adjuvant strategies are advisable.

Human Primary Auditory Cortex Follows the Shape of Heschl's Gyrus.

The primary auditory cortex (PAC) is central to human auditory abilities, yet its location in the brain remains unclear. We measured the two largest tonotopic subfields of PAC (hA1 and hR) using high-resolution functional MRI at 7 T relative to the underlying anatomy of Heschl's gyrus (HG) in 10 individual human subjects. The data reveals a clear anatomical-functional relationship that, for the first time, indicates the location of PAC across the range of common morphological variants of HG (single gyri, partial duplications, and complete duplications). In 20/20 individual hemispheres, two primary mirror-symmetric tonotopic maps were clearly observed with gradients perpendicular to HG. PAC spanned both divisions of HG in cases of partial and complete duplications (11/20 hemispheres), not only the anterior division as commonly assumed. Specifically, the central union of the two primary maps (the hA1-R border) was consistently centered on the full Heschl's structure: on the gyral crown of single HGs and within the sulcal divide of duplicated HGs. The anatomical-functional variants of PAC appear to be part of a continuum, rather than distinct subtypes. These findings significantly revise HG as a marker for human PAC and suggest that tonotopic maps may have shaped HG during human evolution. Tonotopic mappings were based on only 16 min of fMRI data acquisition, so these methods can be used as an initial mapping step in future experiments designed to probe the function of specific auditory fields.

Psychosocial care for the caregivers of primary malignant brain tumor patients.

Despite clinical experience that suggests a high burden of care among relatives of individuals with a primary malignant brain tumor (PMBT), little is known about their actual needs. In this study, the caregivers' personal experiences, quality of life, burden of care, and psychological well-being were examined. Fifty-nine percent did not receive any financial aid for home care, 33% had increased risk for psychosomatic problems, 45% had anxiety, and 33% increased depression levels. The caregiver's quality of life was most strongly affected by the burden of care (p < .001) and the patient's mental state (p < .03). To improve the situation, empathetic professionals and an early implementation of palliative care and social work are required.

Patients with non-insulin depending diabetes mellitus and metabolic syndrome are suboptimal treated in swiss primary care.

The prevalence of complicated hypertension is increasing in America and Europe. This survey was undertaken to assess the status quo of primary care management of hypertension in patients with the high-risk comorbid diseases metabolic syndrome (MetS) and/or type 2 diabetes mellitus (non-insulin depending diabetes mellitus (NIDDM)). Data of anti-hypertensive treatment of 4594 Swiss patients were collected over 1 week. We identified patients with exclusively NIDDM (N = 95), MetS (N = 168), and both (N = 768). Target blood pressure (TBP) attainment, frequency of prescribed substance-classes, and correlations to comorbidities/end-organ damages were assessed. In addition, we analyzed the prescription of unfavorable beta-blockers (BB) and high-dose diuretics (Ds). In NIDDM, Ds (61%), angiotensin receptor blockers (ARBs) (40%), and angiotensin converting enzyme inhibitors (ACEIs) (31%) were mostly prescribed, while in MetS, drugs prevalence was Ds (68%), ARBs (48%), and BB (41%). Polypharmacy in patients with MetS correlated with body mass index; older patients (>65 years) were more likely to receive dual-free combinations. TBP was attained in 25.2% of NIDDM and in 28.7% of MetS patients. In general, low-dose Ds use was more prevalent in NIDDM and MetS, however, overall, Ds were used excessively (NIDDM: 61%, MetS: 68%), especially in single-pill combination. Patients with MetS were more likely to receive ARBs, ACEIs, CCBs, and low-dose Ds than BBs and/or high-dose Ds. Physicians recognize DM and MetS as high-risk patients, but select inappropriate drugs. Because the majority of patients may have both, MetS and NIDDM, there is an unmet need to define TBP for this specific population considering the increased risk in comparison to patients with MetS or NIDDM alone.

Development of Ewing's sarcoma from primary bone marrow-derived mesenchymal stem cells

SUMMARY : Ewing's sarcoma is a member of Ewing's family tumors (ESPY) and the second most common solid bone and soft tissue malignancy of children and young adults. It is associated in 85% of cases with the t(11;22)(q24:q12) chromosomal translocation that generates fusion of the 5' segment of the EWSR1 gene with the 3' segment of the ETS family gene FLI-1. The EWSR1-FLI-1 fusion protein behaves as an aberrant transcriptional activator and is believed to contribute to ESFT development. However, EWSR1-FLI-1 induces growth arrest and apoptosis in normal fibroblasts, and primary cells that are pemissive for its putative oncogenic properties have not been discovered, hampering basic understanding of ESFT biology. Here, we show that EWSR1-FLI-1 alone can transform mouse primary bone marrow-derived mesenchymal progenitor cells and generate tumors that display hallmarks of Ewing's sarcoma, including a small round cell phenotype, expression of ESFT-associated markers, insulin like growth factor-I dependence, and induction or repression of numerous EWSR1-FLI-1 target genes. Consistent with this finding, we tested the possibility that human mesenchymal stem cells (hMSC) might also provide a permissive cellular environment for EWSR1-FLI-1, and could represent the first adequate primary human cellular background for the oncogenic properties of the fusion protein. Indeed, expression of EWSR1-FLI-1 in human mesenchymal stem cells (hMSC) was not only stably maintained without inhibiting proliferation, but induced a gene expression profile bearing striking similarity to that of ESFT, including genes that are among the highest ESFT discriminators. Expression of EWSR1-FLI-1 in hMSCs may recapitulate the initial steps of Ewing's sarcoma development, allowing identification of genes that play an important role early in its pathogenesis. Among relevant candidate transcripts induced by EWSR1-FL/-1 in hMSC we found the polycomb group gene EZH2 which we show to play a critical role in Ewing's sarcoma growth. These observations provide the first identification of candidate primary cells from which ESFTs originate and suggest that EWSR1-FLI-1 expression may constitute the initiating event in ESFT pathogenesis. Le sarcome d' Ewing est un membre de la famille des tumeurs Ewing (ESFT) et représente la deuxième tumeur maligne solide de l'os et des tissus mous chez les enfants et les jeunes adultes. Cette tumeur est associée dans 85% des cas avec la translocation chromosomique t(11;22)(g24:g12), qui génère la fusion entre le segment 5' du gène EWSR1 avec le segment 3' du gène FLI-1, appartenant à la famille des facteurs de transcription ETS. La protéine de fusion EWSR1-FLI-1 qui en dérive joue le rSle d'un facteur de transcription aberrant, et est supposée contribuer de manière décisive au processus de développement des ESFTs. Néanmoins, l'expression de EWSR1-FLI-1 dans des fibroblastes normaux induit un arrêt de croissance et leur apoptose, et les cellules primaires permissives pour les propriétés oncogéniques attribuées à la translocation n'ont pas encore été identifiées, empêchant la compréhension de la biologie de base du sarcome d'Ewing. Dans ce travail on montre que l'expression de EWSR1-FLI-1 uniquement est capable de transformer des cellules souches mésenchymateuses dérivées de la moelle osseuse de la souris, pour générer des tumeurs qui présentent les caractéristiques du sarcome d' Ewing humain, et notamment une morphologie de petites cellules bleues et rondes, l'expression de marqueurs associés aux ESFTs, une dépendance du facteur de croissance IGF-1, et l'induction ou la répression de nombreux gènes cibles connus de EWSR1-FLI-1. Sur la base de ces observations, on a testé la possibilité que les cellules souches mésenchymateuses humaines (hMSCs) puissent aussi fournir un environnement cellulaire permissif pour EWSR1-FLI-1 ; et représenter le premier background cellulaire humain adéquat pour la manifestation du pouvoir oncogénique de la protéine de fusion. En effet, l'expression de EWSR1-FLI-1 dans des cellules souches mésenchymateuses humaines s'est révélée non seulement maintenue, mais elle a induit un profil d'expression génétique étonnamment similaire à celui des ESFTs humains, incluant les gènes qui ont été rapportés comme étant les plus discriminatifs pour ces tumeurs. L'expression de EWSR1-FLI-1 dans les hMSCs pourrait récapituler les étapes initiales du développement du sarcome d' Ewing, et de ce fait consentir à identifier les gènes qui jouent un rôle crucial dans sa pathogenèse précoce. Parmi les transcrits relevant indults par EWSR1-FL/-9 dans les hMSCs nous avons découvert le gène du groupe des polycomb EZH2, que nous avons par la suite démontré jouer un rôle essentiel dans la croissance du sarcome de Ewing. Ces observations apportent pour la première fois l'identification d'une cellule primaire candidate pour représenter la cellule d'origine des ESFTs, et en même temps suggèrent que l'expression de EWSR1-FLI-1 peut constituer l'événement initial dans la pathogenèse du sarcome d' Ewing.
