A French community-based intervention for parents of French-Canadian children with behavior problems: The EQUIPE program.

OBJECTIVES: Behavior problems are one of the most common reasons for seeking mental health services in pediatric populations. The objectives are to evaluate the effects of the EQUIPE program (Étude Québécoise d'Intervention pour les Parents d'Enfants avec des problèmes de comportement) and to analyze the impact of the severity of behavior problems and of parental characteristics. METHODS: This program was translated from the Community Parent Education Program. The effects of EQUIPE, as compared to a control group, were evaluated by using Child Behavior Checklist and Parent Stress Index questionnaires before (T0) and after the intervention program (T1), and at 6 (T2) and 12months (T3) follow-up visits. RESULTS: In total, 533 participants were enrolled in intervention (n=465) (with "severe" or "mild" subgroups according to CBCL-T score) and a control group (n=68). In the two groups, the results showed a statistically significant decrease in Child Behavior Checklist and Parent Stress Index total scores at T1, T2 and T3, with the exception of Child Behavior Checklist total scores in the control group at T2. In the intervention group Child Behavior Checklist total scores were significantly higher in the "severe"; which was not the case for Parent Stress Index total scores at T2 and T3. DISCUSSION: Socioeconomic characteristics, family details, parental medical history and the age of the children appeared to influence changes in Child Behavior Checklist and Parent Stress Index total scores. CONCLUSION: The EQUIPE program is an effective intervention for reducing behavior problems and parents' stress in a French-Canadian population.

Influence of conjugated linoleic acids and vitamin E on biochemical, hematological, and immunological variables of dairy cows during the transition period.

The objective of this experiment was to determine the effects of conjugated linoleic acid (CLA) and vitamin E as well as their interaction on biochemical and hematological variables and on leukocyte populations and their functionality. We assigned 59 German Holstein cows between the 2nd and 9th lactation to 4 dietary groups in a 2 × 2 factorial design with the factors CLA and vitamin E. Six weeks before calving the cows had a BCS of 3.7 to provoke a higher risk of developing ketosis, which might impair their immune function. Blood samples for analyses were taken on d -42, -14, -7, -3, 1, 3, 7, 10, 14, 21, 28, 35, 42, 56, and 70 relative to parturition. Furthermore, peripheral blood mononuclear cells were cultured on d -42, -7, 1, 7, 14, 28, and 70 relative to calving. Most variables were characterized by a high variation between d 7 antepartum and d 7 postpartum. Treatments did not elicit any effect, with the exception of vitamin E, which increased serum urea concentrations and decreased monocyte percentages. Haptoglobin, aspartate-aminotransferase, red blood cell count, leukocyte percentage and populations, as well as peripheral blood mononuclear cells were influenced by parity. In conclusion, the impairment of immune function caused by calving was more severe in cows in ≥3rd parity than in younger cows. However, neither vitamin E nor CLA supplementation was successful to stabilize parity or parturition related variance in hematological and immunological traits.

Influence of conjugated linoleic acids and vitamin E on milk fatty acid composition and concentrations of vitamin A and α-tocopherol in blood and milk of dairy cows.

The objective of this trial was to investigate the influences of conjugated linoleic acid (CLA) and vitamin E (Vit. E) and their interactions on fatty acid composition and vitamins in milk (α-tocopherol, retinol and ß-carotene) as well as on α-tocopherol in blood of pluriparous cows from week 6 ante partum until week 10 post-partum (p.p.). We assigned 59 pluriparous German Holstein cows to four treatment groups with the treatment factors CLA and Vit. E at two levels in a 2 × 2 factorial design. Milk fatty acid composition and milk vitamins were analysed on lactation days 7 and 28. α-tocopherol in blood serum was analysed on days -42, -7, 1, 7, 14, 28 and 70 relative to parturition. Milk concentration of α-tocopherol was influenced by Vit. E (p < .001) and CLA (p = .034). Percentage of cis-9, trans-11 CLA in total milk fat was influenced by treatment with CLA (p < .001), while for percentage of trans-10, cis-12 CLA an interaction between treatment and day (p = .019), driven by an increase in both CLA groups from day 7 to day 28, was found. Serum ratios of α-tocopherol to cholesterol were influenced by Vit. E (p < .001). Results suggest that treatment with CLA during late pregnancy and early lactation is suitable to enhance the proportion of trans-10, cis-12 CLA in milk and thereby influencing nutritional properties. As treatment with Vit. E did not have an impact on milk fatty acid composition, it might be possible to increase the antioxidative capacity of the dairy cow without affecting milk properties. Consequently, combined treatment with CLA and Vit. E might elicit synergistic effects on the cow and milk quality by increasing the proportion of CLA in milk fat as well as the excretion of Vit. E and the Vit. E levels in serum.

The perceived influence of childhood cancer on the parents' relationship.

OBJECTIVE: When a child is diagnosed with cancer, parents are faced with many practical and emotional challenges that can significantly affect their relationship. This study explores how having a child with cancer affects the quality of the parents' relationship, categorizes time points and events during the child's treatment when the relationship becomes most stressed and/or strengthened, identifies factors that help couples remain emotionally engaged throughout their child's cancer treatment, and assesses parental interest in a counseling intervention. METHODS: This is a cross-sectional, multicenter study conducted via a semistructured self-administered questionnaire that included the Revised Dyadic Adjustment Scale. RESULTS: One hundred ninety-two parents of children diagnosed between the ages of 1 and 21 participated. Forty percent felt their relationship moved in a negative direction. Diagnosis and relapse of disease were cited as the most individually stressful time points in the disease trajectory, with hospitalizations and relapse being most stressful on the relationship. Participants felt most emotionally connected at diagnosis and least emotionally connected at the start and end of treatment. The majority of couples indicated interest in counseling to address ways to support their relationship. Soon after diagnosis and during treatment was reported as the preferred time to offer these interventions. CONCLUSION: This study identified specific events and parent behaviors that strain the couples' relationship during the childhood cancer trajectory. This information can inform the development of a couple's intervention. Prospective research is needed to better understand how childhood cancer affects caregivers' partnerships through survivorship and beyond.

Influence of conjugated linoleic acid and vitamin E on performance, energy metabolism, and change of fat depot mass in transitional dairy cows.

The objective of this experiment was to determine the effects of conjugated linoleic acid (CLA) and vitamin E as well as their interaction on performance variables and lipomobilization during late pregnancy and early lactation (wk 6 antepartum until wk 10 postpartum). For this purpose, 59 pluriparous German Holstein cows were assigned to 4 dietary groups in a 2 × 2 design with the factors CLA and vitamin E at 2 levels. For this trial, we selected cows with a high body condition score because they are more likely to mobilize fat and consequently are at a higher risk of developing ketosis. Furthermore, concentrate proportions were adjusted to provoke ketosis. Lactation performance variables were analyzed in 3 periods (d 42 antepartum until calving, 1 to 21 d in milk, 22 to 70 d in milk). Dry matter intake and net energy intake were reduced in animals receiving CLA. Milk fat content was reduced in the CLA group compared with the control group (4.83 vs. 5.46% in period 2; 3.36 vs. 4.57% in period 3). In the vitamin E and the CLA + vitamin E groups, reduction of milk fat content was observed in period 3 (3.76 vs. 4.57% compared with the control group). Milk yield was not affected by treatment. ß-Hydroxybutyrate concentrations and liver lipid contents were not influenced by CLA or vitamin E. Moreover, longitudinal changes of adipose tissue depot mass were not affected by dietary treatments. Results suggest that the effects CLA had on milk composition were compensated by an increased milk yield and a decreased dry matter intake. Reduced milk energy output in CLA-treated animals was compensated by a reduced dry matter intake. Therefore, the net energy balance was not affected by either treatment. Consequently, we found no group effect on the mobilization of adipose tissue.

Puerperal myocardiopathy complicating stimulataneous uterine and tubal pregnancies.

The authors point out the difficulty in recognizing puerperal myocardiopathy and the necessity for standardizing the diagnostic features. The patient described here was all the more unusual because of the coincidental occurrence of a second rare condition-simultaneous uterine and tubal pregnancies. Our data may add support to the theory that all ill-defined myocardial lesion resblts from an autoimmune response.

Pyrrole, furan, and thiophene oxamates as potential antiallergy agents.

Nine heterocyclic oxamic acid derivatives were synthesized and tested in the rat passive cutaneous anaphylactic assay as potential antiallergy agents. Some compounds also were tested for their effects on cholesterol-lipoprotein levels and for diuretic, antidiabetic, and antifertility activities in rats.

Visualizing memory phenotype development after in vitro stimulation of CD4(+) T cells.

Stimulation of naive CD4 cells by specific antigen results in proliferation and changes in cell surface marker expression as the cells differentiate into effector and memory cells. Several of the marker changes (e.g., differences in CD45RB, CD44, and L-selectin levels) appear to be relatively stable and permit the identification of memory T cells. In this study, we examined the acquisition of memory markers after the initial stimulation of naive T cells. CD4(+) T cells from DO11.10 TCR transgenic mice were labeled with the fluorescent dye carboxyfluorescein diacetate succinimidyl ester (CFSE) and were stimulated with specific antigen (OVA323-339). Specific activation was observed, as CFSE-associated fluorescence was reduced twofold with each division of DO11.10 clonotype-bearing cells. Phenotypic changes could also be observed as the cells differentiated into effector/memory cells. However, individual surface markers exhibited a varied relationship to cell division. Although changes in some markers (L-selectin) occurred independently of cell division, changes in other markers were either strictly related to cell division (CD45RB) or were a prerequisite to cell division (CD4, CD44).
