Purpose: To assess the value of positive immunoglobulin (Ig) M serum antibody (Ab) findings in uveitis patients.
Methods: We reviewed medical records of patients who had a positive serological test for Toxoplasma gondii-specific IgM Ab. Their clinical data, including history, demographic characteristics, laboratory findings, clinical findings, treatment outcomes, and recurrences, were reviewed retrospectively.
Results: Of 2919 uveitis patients who underwent a serological test for suspected ocular toxoplasmosis (OT), 18 presented with positive Ig M results. All 18 patients (100.0% specificity) were clinically diagnosed with OT. None had any retinochoroidal scar at the initial visit, indicating the OT was a recent and primary infection. However, 15 patients (83.3%) had no history suspected to account for the Toxoplasma transmission.
Conclusions: The T. gondii IgM serum Ab is a specific biomarker for diagnosis of primary OT. Epidemiological studies are warranted to investigate the non-classic transmission routes of T. gondii in OT. 相似文献
IOX4, a hypoxia-inducible factor stabilizer, is classified as a banned substance for horses in both horse racing and equestrian sports. We recently reported the pharmacokinetic profiles of IOX4 in horse plasma and urine and also identified potential monitoring targets for the doping control purpose. In this study, a long-term longitudinal analysis of IOX4 in horse hair after a nasoesophageal administration of IOX4 (500 mg/day for 3 days) to three thoroughbred mares is presented for the first time for controlling the abuse/misuse of IOX4. Six bunches of mane hair were collected at 0 (pre), 1, 2, 3, and 6 month(s) postadministration. Our results showed that the presence of IOX4 was identified in all postadministration horse hair samples, but no metabolite could be detected. The detection window for IOX4 could achieve up to 6-month postadministration (last sampling point) by monitoring IOX4 in hair. In order to evaluate the longitudinal distribution of IOX4 over 6 months, a validated quantification method of IOX4 in hair was developed for the analysis of the postadministration samples. Segmental analysis of 2-cm cut hair across the entire length of postadministration hair showed that IOX4 could be quantified up to the level of 1.84 pg/mg. In addition, it was found that the movement of the incorporated IOX4 band in the hair shaft over 6 months varied among the three horses due to individual variation and a significant diffusion of IOX4 band up to 10 cm width was also observed in the 6-month postadministration hair samples. 相似文献
AbstractPurposes/objectives: This paper reports the comparative efficacies of integrative body-mind-spirit intervention (I-BMS) and cognitive behavioral therapy (CBT) in patient-caregiver parallel groups for Chinese patients with lung cancer.Design: Randomized controlled trial (RCT).Methods: One hundred and fifty-seven patient-caregiver dyads with no marked functional impairment were randomized into one of the two interventions with eight weekly patient-caregiver parallel groups. Assessments were conducted at baseline, within one, eight- and sixteen-weeks post-intervention. Effects of treatment group across time were analyzed by multilevel modeling.Findings: CBT led to greater reduction in emotional vulnerability than I-BMS. I-BMS resulted in greater increase in overall QoL and spiritual self-care, and more reduction in depression than CBT. Patients in both interventions experienced improvement in physical, emotional and spiritual, except social, domains of QoL.Conclusion: I-BMS was more efficacious for diverse domains of QoL, and CBT was more effective for emotional well-being, despite the relatively small between-group effect sizes.Implications for psychosocial providers/policy: (1) With the expanding repertoire of psychosocial interventions for families facing lung cancer, it has become imperative to investigate the comparative efficacies of empirically supported and culturally adapted interventions. (2) Our findings show that I-BMS was more effective for diverse domains of QoL, while CBT was more efficacious with emotional well-being, although both interventions led to significant improvements in physical, emotional and spiritual domains of patient QoL. (3) Patient-caregiver parallel groups have been shown to be effective for enhancing QoL of Chinese lung cancer patients. (4) Care professionals are encouraged to dispense interventions based on the idiosyncratic needs and preferences of the patients to maximize the treatment effects. 相似文献
