Fathers of persons with mental illness: a preliminary study of coping capacity and service needs

The effects of a single dose of caffeine on specific information processing operations were examined by using a visual selective attention task in which subjects were asked to select between a left and right hand response on the basis of two different target letters. The target was presented on a predefined position in the visual field and was either presented alone or with flanker letters, calling for the correct, the incorrect or no specific response. A dose of 3 mg/kg body weight caffeine or lactose, dissolved in a cup of decaffeinated coffee, was administered double blind and deceptively to overnight abstinence coffee drinkers. Behavioural measures were supplemented by psychophysiological measures. The present results replicated the basic findings obtained in this paradigm. The results indicated that the time to localise the target decreased and response preparation started earlier after caffeine than after placebo. These caffeine effects did not interact with the time subjects spent on the task or with the reaction time distribution, which might be due to a high level of practice.     

Do Gender and Racial Differences Between Patient and Therapist Affect Therapeutic Alliance and Treatment Retention in Adolescents?

Parents, referral sources, and even therapists wonder whether the gender and racial match between therapists and patients contributes to poorer alliances and treatment dropout. Six hundred adolescent substance abusers and their therapists from a large randomized clinical trial were grouped according to matches and mismatches on both gender and race, and alliance ratings were collected from both patients and therapists. Results revealed that gender-matched dyads reported higher alliances and were more likely to complete treatment. Racial matching predicted greater retention but not patient-rated alliance. However, therapists in mismatched dyads rated significantly lower alliances. Results suggest that, although multicultural training remains critical, training emphasis should also be placed on understanding how gender and racial differences affect therapeutic processes.

The therapeutic alliance in adolescent substance abuse treatment: A one-with-many analysis.

Studies of the therapeutic alliance typically use a one-with-many (OWM) design in which each therapist (the one) treats multiple clients (the many). This study used Kenny, Kashy, and Cook's (2006) OWM method to examine the composition of the therapeutic alliance and to analyze the association between alliance and outcome in a sample of 398 adolescents treated for substance abuse by 14 therapists. Both the client and therapist alliance ratings yielded large relationship variances, with limited consensus among clients treated by the same therapist about the quality of the alliance. If a client reported an especially strong alliance with his or her therapist, the therapist was likely to also report an especially strong alliance with that client (dyadic reciprocity). The association between the components of the alliance and treatment outcome was complicated, with different levels of measurement and different components of the alliance (perceiver, partner, or relationship) derived from different informants (therapist or client) relating to different outcomes.

Effect of Heat Treatment on Antioxidant Capacity and Flavor Volatiles of Mead

ABSTRACT: The objective of this study was to evaluate the effects of heat processing on the antioxidant capacity of mead (honey wine). Soy and buckwheat honey musts were subjected to 2 heat treatments and fermented into wine. Total phenolic concentration was determined. High-performance liquid chromatography (HPLC) phenolic profiling was performed on the methanol fraction of Amberlite extraction. Antioxidant capacity was evaluated using the oxygen radical absorbance capacity (ORAC) assay. Changes in volatile components were evaluated by headspace-solid phase microextraction/gas chromatography-mass spectrometry (H-SPME/GC-MS). ORAC values of experimental meads (3.62 m M Trolox equivalent) were comparable to those of commercial white wine (3.66 m M Trolox equivalent). No significant difference in antioxidant capacity due to heat treatment or honey type was observed. There was no difference in total phenolics between heat treatments in buckwheat mead; however, soy mead made from high-heated must had significantly greater phenolic concentration than the gently heated mead (α= 0.05). Linear regression analysis indicated a strong positive correlation between total phenolic concentration and antioxidant capacity by ORAC ( r = 0.9077; P < 0.0001). HPLC analysis of phenolic profiles in the methanol fractions of Amberlite extraction of the meads indicated significantly higher levels of certain phenolics as a result of the high-heat process in buckwheat mead, but not in soy mead. Differences in volatile components that potentially impact flavor were noted between high and low heat treatments. Results of this study suggest dramatic heat treatments that are often avoided because their flavor impact in mead production have the potential to alter the antioxidant capacity of mead by changing phenolic profiles.     

Factors associated with self-reported, pesticide-related visits to health care providers in the agricultural health study

To investigate factors associated with pesticide-related visits to health care providers (i.e., doctor or hospital visits), responses to self-administered questionnaires received from 35,879 licensed restricted-use pesticide applicators participating in the Agricultural Health Study were analyzed. (In Iowa, applicators are actually certified, whereas in North Carolina they are licensed; for ease of reference, the term license will be used for both states in this paper.) The cohort reported a total of more than 10.9 million pesticide-application days. These applications were associated with one or more pesticide-related health care visits by 2,214 applicators (7.0% of the applicator cohort for whom health care visit data were available). The odds of a pesticide-related health care visit were increased for commercial applicators compared to private applicators [odds ratio (OR = 1.77; 95% confidence interval (CI), 1.52-2.06) and for applicators who used insecticides 70 times or more in their lifetime compared to those who used insecticides less frequently (OR = 1.43; CI, 1.26-1.63). After adjusting for the number of applications in a logistic regression model, significantly higher odds of health care visits were observed among North Carolina applicators compared to Iowa applicators (OR = 1.35; CI, 1.17-1.52), among applicators who mixed their own pesticides (OR = 1.65; CI, 1. 22-2.23), and among applicators who personally repaired their pesticide application equipment at least once per year (OR = 1.12; CI, 1.06-1.25). Significantly lower odds were found among female versus male applicators (OR = 0.68; CI, 0.46-0.99) and among applicators who graduated from high school versus those who did not (OR = 0.82; CI, 0.71-0.94 for high school graduates and OR = 0.79; CI, 0.68-0.91 for those with at least some college). Several methods of pesticide application to crops, seed, or stored grain were also associated with significantly elevated odds ratios of health care visits. These observations suggest that several steps can be taken to reduce the number of health care visits resulting from occupational exposure to pesticides. The implications of this pattern of pesticide-related health care visits may have etiologic implications for cancer and other chronic diseases.
