Sixty-six patients with human immunodeficiency virus infection and diarrhoea caused by Cryptosporidium parvum were enrolled in a double-'blind' placebo-controlled study to evaluate the safety and efficacy of nitazoxanide in the treatment of cryptosporidiosis related to the acquired immune deficiency syndrome. Patients were randomly assigned to one of 3 treatment groups and received either 500 mg twice daily of nitazoxanide, 1000 mg twice daily of nitazoxanide, or placebo orally for 14 d; the patients on nitazoxanide then crossed over to placebo while the placebo patients crossed over to nitazoxanide therapy at either the high or low dose depending on their randomization. Three post-treatment faecal examinations were conducted on days 15, 22 and 29 following initiation of treatment: patients were considered 'cured' if none revealed any C. parvum oocysts. Both doses of nitazoxanide produced parasitological cure rates superior to the placebo responses (12/19 [63%, P = 0.016] for patients receiving 1 g/d and 10/15 [67%, P = 0.013] for those receiving 2 g/d). Parasitological cure was correlated with the complete resolution of the diarrhoeal syndrome in 19 of the 22 treated patients who were considered parasitologically cured (86%). Both doses of nitazoxanide were well tolerated by the patients.

BackgroundTo confirm the internal structure of the Health Related Quality of Life for Eating Disorders version 2 questionnaire (HeRQoLEDv2) and create and validate a shortened version (HeRQoLED-S).Methods324 patients with eating disorders were assessed at baseline and one year later (75.6% of whom responded). We performed a confirmatory factor analysis of the HeRQoLEDv2 using baseline data, and then a Rasch analysis to shorten the questionnaire. Data obtained at year one was used to confirm the structure of the HeRQoLED short form and evaluate its validity and reliability.ResultsTwo latent second-order factors -- social maladjustment and mental health and functionality -- fit the data for the HeRQoLEDv2. Rasch analysis was computed separately for the two latent second-order factors and shortened the HeRQoLEDv2 to 20 items. Infit and outfit indices were acceptable, with the confirmatory factor analysis of the HeRQoLED short form giving a root mean square error of approximation of 0.07, a non-normed fit index and a comparative fit index exceeding 0.90. The validity was also supported by the correlation with the convergent measures: the social maladjustment factor correlated 0.82 with the dieting concern factor of the Eating Attitudes Test-26 and the mental health and functionality factor correlated -0.69 with the mental summary component of the Short Form-12. Cronbach alphas exceeded 0.89.ConclusionsTwo main factors, social maladjustment and mental health and functionality, explain the majority of HeRQoLEDv2 scores. The shortened version maintains good psychometric properties, though it must be validated in independent samples.

The objectives of the authors in this study were two-fold: (1) to explore the role of resilience in recovery from eating disorders (EDs), and (2) to develop a model of resilience in women with EDs. Semi-structured interviews with ten women were conducted in April 2011, along with two focus groups with women who had recovered from EDs (n  = 5 women each; conducted in April 2012 at the University of Deusto, Spain), one focus group with clinical experts (n = 8; conducted in April 2012 at the Foundation Against EDs of Biskay, Spain), and six narratives from primary caregivers of ED patients living in Biskay, Spain (conducted in November 2012). All data were analyzed using a grounded theory approach. All female participants acknowledged experiencing resilience in their recovery. The analysis resulted in a conceptual model of resilience composed of the following categories: deep dissatisfaction with life, turning point, acceptance, hope, determination to change, accountability for the ED, active coping, getting social support, gaining self-knowledge, getting information about EDs, increase well-being, trait resilience, initiating new projects and living in the here and now. According to the model presented, resilience preceded the experience of recovery in women with EDs in this sample and could be a useful asset for future interventions.
