Implementing Parental Tobacco Dependence Treatment Within Bronchiolitis QI Collaboratives.

BACKGROUND AND OBJECTIVES: We sought to implement systematic tobacco dependence interventions for parents and/or caregivers as secondary aims within 2 multisite quality improvement (QI) collaboratives for bronchiolitis. We hypothesized that iterative improvements in tobacco dependence intervention strategies would result in improvement in outcomes between collaboratives. METHODS: This study involved 2 separate yearlong, multisite QI collaboratives that were focused on care provided to inpatients with a primary diagnosis of bronchiolitis. In each collaborative, we provided tools and training in tobacco dependence treatment and expert coaching on interventions for parents as a secondary aim. Data were collected by chart review and results analyzed by using analysis of means and statistical process control analysis. Outcomes between collaboratives were compared by using relative risks. RESULTS: Between both collaboratives, 56 hospitals participated and 6258 inpatient charts were reviewed. In the first collaborative, 22% of identified parents who smoke received tobacco dependence interventions at baseline. This rate increased to 51% during the postintervention period, with special cause revealed by analysis of means. In the second collaborative, 31% of parents who smoke received baseline interventions. This rate increased to 53% by the conclusion of the collaborative, with special cause revealed by statistical process control analysis. The relative risk for providing any cessation intervention in 1 collaborative versus the other was 0.9 (confidence interval 0.8-1.1). CONCLUSIONS: Tobacco dependence treatment of parents and/or caregivers can be integrated into bronchiolitis QI by using relatively low-resource strategies. Using a more intensive QI intervention did not alter the rates of screening or intervention for caregivers who smoke.

Effects of Curcuminoids-Piperine Combination on Systemic Oxidative Stress, Clinical Symptoms and Quality of Life in Subjects with Chronic Pulmonary Complications Due to Sulfur Mustard: A Randomized Controlled Trial.

Oxidative stress plays a key role in the development of chronic pulmonary complications of sulfur mustard (SM). Curcuminoids are polyphenols with documented safety and antioxidant activity. The present study aimed to investigate the efficacy of short-term supplementation with curcuminoids (co-administered with piperine to enhance the bioavailability of curcuminoids) in alleviating systemic oxidative stress and clinical symptoms, and improvement of health-related quality of life (HRQoL) in subjects suffering from chronic pulmonary complications due to SM exposure who are receiving standard respiratory treatments. Eighty-nine subjects were recruited to this randomized double-blind placebo-controlled trial, being randomly allocated to either curcuminoids (1500 mg/day) + piperine (15 mg/day) combination (n = 45) or placebo (n = 44) for a period of 4 weeks. High-resolution computed tomography suggested the diagnosis of bronchiolitis obliterans in all subjects. Efficacy measures were changes in serum levels of reduced glutathione (GSH) and malonedialdehyde (MDA). The severity and frequency of respiratory symptoms and HRQoL were also assessed using St. George respiratory Questionnaire (SGRQ) and COPD Assessment Test (CAT) indices. Serum levels of GSH were increased whilst those of MDA decreased by the end of trial in both groups. Likewise, there were significant improvements in the total as well as subscale (symptoms, activity and impact) SGRQ and CAT scores in both groups. However, comparison of magnitude of changes revealed a greater effect of curcuminoids-piperine combination compared to placebo in elevating GSH, reducing MDA and improving CAT and SGRQ (total and subscale) scores (p < 0.001). Regarding the promising effects of curcuminoids on the measures of systemic oxidative stress, clinical symptoms and HRQoL, these phytochemicals may be used as safe adjuvants in patients suffering from chronic SM-induced pulmonary complications who are receiving standard treatments.

¿Hay una asociación entre deficiencia de vitamina D y riesgo de bronquiolitis y asma bronquial en la infancia?: Una revisión crítica / Is there a relation between vitamin D deficiency and an increased risk for bronchiolitis and bronchial asthma in childhood?: A critical revision

Se revisa críticamente la información científica relacionada con deficiencia de vitamina D (DVD) y riesgo de infecciones respiratorias agudas bajas (IRAB) o asma bronquial en niños. Las IRAB, en especial por virus respiratorio sincicial (VRS) están asociadas a una alta carga de enfermedad. Al no contar aún con una vacuna para ellas, las medidas preventivas y de sostén son las más importantes. El DVD es prevalente en todos los ambientes geográficos, con consecuencias ligadas al metabolismo de calcio y óseo, pero también alteraciones de la inmunidad. Hay evidencia inicial de una asociación entre DVD y mayor riesgo de IRAB, especialmente durante los primeros meses de vida; alelos de algunos polimorfismos del receptor de vitamina D podrían asociarse a un mayor riesgo de IRAB. Este escenario cosmopolita, justifica estudiar el impacto de medidas de suplementación de VD adaptadas a las realidades locales, a la madre durante el embarazo y/o al niño en los primeros meses de vida, que impacten sobre el riesgo de presentar IRAB y asma.

We critically review the information about vitamin D deficiency (VDD) and risk of lower respiratory infections and asthma in children. Acute lower respiratory infections (ALRI), particularly those due to respiratory syncytial virus (RSV) are associated with a high burden of disease. In theabsence of a vaccine for them, prevention and support during illness are important measures to reduce the risk of acquiring the condition or decreasing its severity. VDD has been described as prevalent in all geographical environments; its consequences are linked to calcium and bone metabolism, but also to impaired immunity. Recent evidence of an association between VDD and increased risk of ALRI, especially during the first few months of life has been demonstrated; alleles of some polymorphism of vitamin D receptor may be involved in an increased risk of LRTI. It is justified to study the impact of measures of vitamin D supplementation adapted to local environments, including the appropriate doses to the mother during pregnancy and/or to the child in the first months of life, on the risk of ALRI, or asthma in later ages.

Vitamin D deficiency and acute lower respiratory infections in children younger than 5 years: identification and treatment.

INTRODUCTION: Acute lower respiratory infection (ALRI) is a leading cause of childhood mortality. Research suggests that vitamin D deficiency (VDD) puts children at risk for ALRI. The purpose of this review is to examine ALRI and VDD in children 5 years and younger. Common etiologies, diagnosis, prevention, treatment of ALRI, and recommendations for vitamin D supplementation are summarized. METHOD: Databases were searched for studies investigating VDD and ALRI in children. Independent reviewers assessed the internal validity of the studies. RESULTS: Of 18 studies examined, VDD was found to be associated with increased risk or severity of ALRI in 13 studies; associations were not found in 4 studies. In one study it was found that high maternal vitamin D levels was associated with ALRI in infants. DISCUSSION: Vitamin D supplementation is a low-cost, low-risk intervention that providers should consider for children, especially those at high risk for ALRI. Practitioners should follow current recommendations when prescribing vitamin D supplementation for infants and children.

[Vitamin D intake in young children with acute lower respiratory infection].

OBJECTIVE: To determine if vitamin D intake is associated with acute lower respiratory infections (ALRI) in children. METHODS: The vitamin D intakes of children younger than 5 years of age admitted to hospital with either bronchiolitis or pneumonia were compared to an unmatched control group of the same age without respiratory infection. Caregivers of 197 children completed a questionnaire collecting information on demographic variables, ALRI risk factors and diet. Associations of ALRI with vitamin D intake and other ALRI risk factors were determined. RESULTS: The mean vitamin D intake of children with ALRI was 48 IU/kg/d compared to 60 IU/kg/d in the control group. When controlling for age, ethnicity, socio-economic status, northern residence, breastfeeding, immunizations and smoking contact, children with a vitamin D intake of less than 80 IU/kg/d were greater than 4 times more likely to have ALRI compared to children with a vitamin D intake exceeding 80 IU/kg/d (OR=4.9; 95%CI: 1.5-16.4). CONCLUSIONS: A higher vitamin D intake than currently recommended might be needed to offer protection against diseases such as ALRI. Increased vitamin D supplementation could have important public health consequences, as bronchiolitis and pneumonia are the most common reasons for hospitalization in young children.

Malaria infection does not appear to modify the risk of bronchiolitis early in life.

BACKGROUND: The observation of an increased prevalence of allergic disorders coinciding with a decreasing frequency of infectious diseases in early childhood has led to the speculation that infections may prevent allergic sensitization. Information on the role of parasites in this context is limited. Bronchiolitis in infancy has been linked with asthmatic symptoms later in childhood, although the underlying cause of this association is unknown. METHODS: To test the hypothesis that early parasitic infections in infancy might prevent the development of allergic manifestations later in life, the effect of malaria infections during the first year of life on the risk of bronchiolitis was studied in 675 Tanzanian children at 18 months of age. The study was conducted as part of an intervention trial of malaria chemoprophylaxis and/or iron supplementation for the prevention of malaria and anemia in infants. RESULTS: The incidence of bronchiolitis up to 18 months of age in the 675 children was 0.58 episode per child per year. The risk factors analysis was based on 470 children with complete data. There was no difference in the incidence of bronchiolitis between those who had received malaria chemoprophylaxis during the first year of life and those who had not. However, the proportion of children who had bronchiolitis was lower among those who had had malaria episodes than among those who had not (48% vs. 55%, P = 0.05). CONCLUSIONS: This study does not support the hypothesis that reduced exposure to parasites may modulate the development of bronchiolitis early in life.
