Psychiatric symptoms and cognition were assessed in 13 patients with schizophrenia, one patient with schizoaffective disorder, and one patient with psychosis not otherwise specified while they received a conventional neuroleptic and again after an average of 15 months on clozapine. Despite improvements in psychiatric symptoms, attention, memory, and higher-level problem-solving were essentially unchanged. This suggests that certain cognitive deficits are relatively independent of psychotic symptoms in schizophrenia, and are probably central and enduring features of the disorder. Cognitive disability appeared to have been rate-limiting in the sample's rehabilitation, as patients' social and vocational adjustment remained marginal during the study. We also observed that treatment with clozapine was associated with a decline in some memory functions; the potent anticholinergic properties of the drug may have been responsible for this.
This clinical project compares the relative impact of two types of multiple family groups on psychiatric inpatients and their families. Forty patients with a diagnosis of affective disorder, and their family members, were randomly assigned to a traditional multiple family group with a process orientation that emphasized support, destigmatization, and self-help about common problems; or to a psychoeducational multiple family group that emphasized the provision of information about the patient's illness and methods of coping with it effectively. Both groups, which met for four hours on a Saturday afternoon, were an integral part of an ongoing inpatient program specializing in the treatment of affective disorders. Pre- and post-measures were obtained regarding family and patient knowledge about affective disorders, level of personal distress, attitudes about the illness, and dyadic adjustment. In addition, both patients and family members were asked to rate their satisfaction with the group experience. A number of differences in knowledge, attitude and dyadic adjustment were found in the participants of both groups immediately following their respective group sessions, but there were only a few statistically significant differences between the two groups. Those who attended the psychoeducational session, however, reported significantly more satisfaction with the experience.
These results suggest that patients with schizophrenia perform systematically worse on cognitive measures than patients with affective disorders, which is consistent with their generally poorer outcome. The results also indicate that schizophrenia and affective disorders are qualitatively distinguishable in neuropsychological terms, given differences in apparent intellectual deterioration, profiles of cognitive impairment, and associations between cognitive performance and psychopathology.
Despite their widespread use, there are few data concerning the effects of tricyclic antidepressants on EEG sleep in depression. The present study documented the effects of desipramine (DMI, n = 17) and amitriptyline (AT, n = 16) upon EEG sleep in hospitalized depressed patients as part of a double-blind protocol involving 28 days of active treatment. Compared to placebo, patients receiving DMI showed somewhat worsened sleep continuity, particularly after 1 week of administration when the dose was 150 mg/day. On the other hand, sleep architecture and REM measures showed a rapid suppression of REM sleep, and then partial tolerance for this effect was observed with continued administration of DMI for 3 weeks. DMI was a more potent suppressor of REM sleep, while AT was more sedative. Based on these differences in effects upon EEG sleep, a discriminant function was derived and resulted in a correct classification of 87.5% of AT cases and 76.5% of DMI cases. These results are discussed in terms of the differences in pharmacological profiles for uptake blockade and anticholinergic potency for these two compounds.
AIMSThe aim of the present study was to investigate the safety, tolerability and pharmacokinetics of coadministered azithromycin (AZI) and piperaquine (PQ) for treating malaria in pregnant Papua New Guinean women. METHODSThirty pregnant women (median age 22 years; 16-32 weeks' gestation) were given three daily doses of 1 g AZI plus 960 mg PQ tetraphosphate with detailed monitoring/blood sampling over 42 days. Plasma AZI and PQ were assayed using liquid chromatography-mass spectrometry and high-performance liquid chromatography, respectively. Pharmacokinetic analysis was by population-based compartmental models. RESULTSThe treatment was well tolerated. The median (interquartile range) increase in the rate-corrected electrocardiographic QT interval 4 h postdose [12 (6-26) ms 0.5 ] was similar to that found in previous studies of AZI given in pregnancy with other partner drugs. Six women with asymptomatic malaria cleared their parasitaemias within 72 h. Two apararasitaemic women developed late uncomplicated Plasmodium falciparum infections on Days 42 and 83. Compared with previous pregnancy studies, the area under the concentration-time curve (AUC 0-∞ ) for PQ [38818 (24354-52299) μg h l À1 ] was similar to published values but there was a 52% increase in relative bioavailability with each dose. The AUC 0-∞ for AZI [46799 (43526-49462) μg h l À1 ] was at least as high as reported for higher-dose regimens, suggesting saturable absorption and/or concentration-dependent tissue uptake and clearance from the central compartment. CONCLUSIONSAZI-PQ appears to be well tolerated and safe in pregnancy. Based on the present/other data, total AZI doses higher than 3 g for the treatment and prevention of malaria may be unnecessary in pregnant women, while clearance of parasitaemia could improve the relative bioavailability of PQ.
The effects of amitriptyline (n = 14) or zimelidine (n = 13) on the sleep electroencephalogram of hospitalized depressed patients were assessed in a double-blind protocol involving 28 days of active dosing. Zimelidine induced no immediate improvement in sleep continuity, and even after 3 wk on zimelidine subjects tended to have longer sleep latency, more awakenings, and lighter non-rapid eye movement (REM) sleep than before taking the drug. Zimelidine did, however, induce a rapid and persistent alteration of sleep architecture and selected REM measures. REM sleep, which was suppressed over the first two nights on zimelidine, was maximally suppressed after 1 wk, but by 3 wk there was some tolerance for selected REM measures. While zimelidine induced none of the sedative effects of amitriptyline, both were equivalent in their REM-suppressant effects. These findings are discussed in terms of the differences in uptake blockade and anticholinergic potency in these two drugs.
Introduction: Low education levels may limit community-based health worker (CHW) efforts in rural Afghanistan. In 2004, LeapFrog Enterprises and the United States Department of Health and Human Services developed the Afghan Family Health Book (AFHB), an interactive, electronic picture book, to communicate public health messages in rural Afghanistan. Changes in health knowledge among households exposed to the AFHB vs. CHWs were compared.Methods: From January–June 2005, baseline and follow-up panel surveys were administered in Pashto-speaking Laghman and Dari-speaking Kabul provinces. Within each province, an AFHB and a CHW district were randomly sampled using a stratified, 2-staged cluster sample design (total 98 clusters and 3,372 households). Surveys tested knowledge of 17 health domains at baseline and on follow-up at three months. For each domain, multivariate logistic regression was used to assess the effect of the AFHB on follow-up pass rates, controlling for demographics and differences in baseline knowledge.Results: Both AFHB and CHW resulted in statistically significant changes in pass rates on follow-up, although there were greater gains among AFHB users for five domains among Pashto-speakers (micronutrients, malaria, sexually transmitted diseases, postpartum care, and breast-feeding) and seven domains among Dari-speakers (diet, malaria, mental health, birth-spacing, and prenatal/neonatal/postpartum care). Community-based health workers effected greater knowledge gains only for the Dari breast-feeding module. Participants favored CHW over the AFHB, which they found poorly translated and difficult to use.Conclusions: The AFHB has potential to improve public health knowledge among rural Afghans. Future efforts may benefit from involvement of local health agencies and the integration of interactive technology with traditional CHW approaches.
