The association of neighbourhood and individual social capital with consistent self-rated health: a longitudinal study in Brazilian pregnant and postpartum women.

BACKGROUND: Social conditions, social relationships and neighbourhood environment, the components of social capital, are important determinants of health. The objective of this study was to investigate the association of neighbourhood and individual social capital with consistent self-rated health in women between the first trimester of pregnancy and six months postpartum. METHODS: A multilevel cohort study in 34 neighbourhoods was performed on 685 Brazilian women recruited at antenatal units in two cities in the State of Rio de Janeiro, Brazil. Self-rated health (SRH) was assessed in the 1st trimester of pregnancy (baseline) and six months after childbirth (follow-up). The participants were divided into two groups: 1. Good SRH--good SRH at baseline and follow-up, and, 2. Poor SRH--poor SRH at baseline and follow-up. Exploratory variables collected at baseline included neighbourhood social capital (neighbourhood-level variable), individual social capital (social support and social networks), demographic and socioeconomic characteristics, health-related behaviours and self-reported diseases. A hierarchical binomial multilevel analysis was performed to test the association between neighbourhood and individual social capital and SRH, adjusted for covariates. RESULTS: The Good SRH group reported higher scores of social support and social networks than the Poor SRH group. Although low neighbourhood social capital was associated with poor SRH in crude analysis, the association was not significant when individual socio-demographic variables were included in the model. In the final model, women reporting poor SRH both at baseline and follow-up had lower levels of social support (positive social interaction) [OR 0.82 (95% CI: 0.73-0.90)] and a lower likelihood of friendship social networks [OR 0.61 (95% CI: 0.37-0.99)] than the Good SRH group. The characteristics that remained associated with poor SRH were low level of schooling, Black and Brown ethnicity, more children, urinary infection and water plumbing outside the house. CONCLUSIONS: Low individual social capital during pregnancy, considered here as social support and social network, was independently associated with poor SRH in women whereas neighbourhood social capital did not affect women's SRH during pregnancy and the months thereafter. From pregnancy and up to six months postpartum, the effect of individual social capital explained better the consistency of SRH over time than neighbourhood social capital

Supplementary Material for: Cor a 14: Missing Link in the Molecular Diagnosis of Hazelnut Allergy?

<b><i>Background:</i></b> Hazelnut allergy shows distinct clinical patterns that can be predicted through component-resolved diagnosis. However, identification of sensitization profiles remains incomplete. <b><i>Methods:</i></b> Sera of 75 patients allergic to hazelnuts, 14 infants with atopic dermatitis (AD) sensitized to hazelnuts, 15 hazelnut-tolerant individuals with specific IgE (sIgE) to hazelnuts and 15 healthy control individuals were tested for sIgE reactivity to rCor a 1.04, rCor a 8, nCor a 9, nCor a 11, rCor a 14, rBet v 1, rBet v 2 and cross-reactive carbohydrate determinants (CCDs). <b><i>Results:</i></b> Sensitization to Cor a 14 was observed in 18 out of 20 preschool children, 8 out of 10 school-aged children and 2 out of 7 adults with generalized reactions and in 3 out of 14 infants with AD. Only 2 out of 38 patients with an oral allergy syndrome (OAS) were sensitized to Cor a 14. No sensitization to Cor a 14 was observed in the group of hazelnut-tolerant and healthy control individuals. Sensitization to Cor a 1.04 was seen in 36 out of 38 OAS patients and in 14 out of 37 patients with generalized reactions. However, only 3 patients with generalized reactions were monosensitized to Cor a 1.04. Sensitization to Cor a 9 was observed in 26 out of 37 patients with generalized reactions and in 4 out of 14 infants with AD. Sensitization to Cor a 11, Cor a 8, rBet v 2 and CCDs was rare. <b><i>Conclusions:</i></b> Sensitization to Cor a 14 can have early onset and shows age-related variations. Together with Cor a 9, Cor a 14 enables us to correctly identify almost 90% of children with generalized reactions to hazelnut

Minimally invasive versus open distal pancreatectomy (LEOPARD): study protocol for a randomized controlled trial

Abstract Background Observational cohort studies have suggested that minimally invasive distal pancreatectomy (MIDP) is associated with better short-term outcomes compared with open distal pancreatectomy (ODP), such as less intraoperative blood loss, lower morbidity, shorter length of hospital stay, and reduced total costs. Confounding by indication has probably influenced these findings, given that case-matched studies failed to confirm the superiority of MIDP. This accentuates the need for multicenter randomized controlled trials, which are currently lacking. We hypothesize that time to functional recovery is shorter after MIDP compared with ODP even in an enhanced recovery setting. Methods LEOPARD is a randomized controlled, parallel-group, patient-blinded, multicenter, superiority trial in all 17 centers of the Dutch Pancreatic Cancer Group. A total of 102 patients with symptomatic benign, premalignant or malignant disease will be randomly allocated to undergo MIDP or ODP in an enhanced recovery setting. The primary outcome is time (days) to functional recovery, defined as all of the following: independently mobile at the preoperative level, sufficient pain control with oral medication alone, ability to maintain sufficient (i.e. &gt;50%) daily required caloric intake, no intravenous fluid administration and no signs of infection. Secondary outcomes are operative and postoperative outcomes, including clinically relevant complications, mortality, quality of life and costs. Discussion The LEOPARD trial is designed to investigate whether MIDP reduces the time to functional recovery compared with ODP in an enhanced recovery setting.
