    Notes: Abstract We examined whether psychiatric patients knew their diagnosis, the significance they attached to it, and the impact of being informed in a systematic fashion according to their wishes. We also assessed whether the nature of the psychiatric diagnosis influenced what patients were told by their psychiatrists. The three parts of the study included questionnaire responses from 28 consultant psychiatrists; case-note reviews and questionnaire responses of 200 adult psychiatric in-patients; and a pilot study informing 28 adult psychiatric day hospital patients of their diagnosis according to their wishes. The results showed that of 126 in-patients, 53% had not been told their diagnosis, although most wanted to know. Of those informed, 75% agreed with their diagnosis. The majority of patients considered a psychiatric diagnosis to be as real as a physical diagnosis and helpful in their treatment. Patients with schizophrenia were less likely to have been informed of their diagnosis, and psychiatrists were also more reticent regarding the diagnosis of personality disorder. All patients who were systematically informed, in the pilot study, agreed with their diagnosis. We conclude that most patients agree with their diagnosis and its usefulness. All patients should be asked whether they want to know their diagnosis and be informed appropriately.

    Notes: Abstract   Diurnal changes in titratable acidity, photosynthesis, energy dissipation activity, and the carotenoid composition of differently oriented cladodes of the cactus Opuntia macrorhiza were characterized during exposure to full sunlight in the field. Four cladode faces were chosen such that each was exposed to maximum photon flux densities (PFD) at different times of the day in addition to receiving different daily integrated PFDs. The sum of all carotenoids per chlorophyll was found to increase with increasing exposure to PFD, with the carotenoids of the xanthophyll cycle present in the most exposed face at more than twice the concentration found in the least exposed face. All faces exhibited large increases in xanthophyll cycle-dependent energy dissipation as the sun rose in the morning, even those receiving only minimal levels of diffuse radiation. The transient high levels of energy dissipation in those faces that did not receive direct sunlight in the morning may have been due to low temperature inhibition of photosynthesis (predawn low of 2°C). For the two faces receiving peak PFDs in the morning hours (north and east faces), the level of energy dissipation activity increased rapidly during exposure to direct sunlight in the early morning, gradually declining in the late morning under warm temperatures, and was negligible during the afternoon low light conditions. Changes in the xanthophyll cycle paralleled the changes in energy dissipation with the majority of the cycle present as violaxanthin (V) prior to sunrise, largely de-epoxidized to zeaxanthin (Z) and antheraxanthin (A) during exposure to direct sunlight, and reconverted to V during the afternoon. For the two faces receiving peak PFDs in the afternoon (south and west faces), energy dissipation activity increased dramatically during the early morning low light period, subsequently decreasing during midday as decarboxylation of malic acid proceeded maximally (providing a high concentration of CO2 for photosynthesis), and then increased to the highest level in the late afternoon as the supply of malic acid was depleted and rates of photosynthetic electron transport declined. The xanthophyll cycle, largely present as Z and A prior to sunrise in the south and west faces, was de-epoxidized to the greatest extent in the late afternoon, followed by epoxidation back to the predawn level by sunset. In all cladode faces high levels of energy dissipation activity were accompanied by decreases in the intrinsic efficiency of photosystem II (PSII), indicative of a regulatory process that diverted the excess energy away from the reaction centers during periods of excess light. Furthermore, the overnight retention of Z and A by the south and west faces was accompanied by a sustained reduction in PSII efficiency (i.e., “photoinhibition”). We suggest that this “photoinhibition” represents the sustained engagement of nocturnally retained Z and A in the photoprotective down-regulation of PSII.

    Notes: Abstract Patient satisfaction can be a useful marker in evaluating the quality of psychiatric care. However, this form of measurement has been hampered by the lack of attention paid to the psychometric properties of instruments devised. The Psychiatric Care Satisfaction Questionnaire (PCSQ) was developed and tests of acceptability, validity and reliability were undertaken using 52 inpatients. Content validity was assessed by surveying psychiatrists, other mental health professionals, MIND workers and patient groups. Thirty-six (67.9%) of all mental health professionals felt that the questionnaire was a useful measure of patients' satisfaction with their care, and many comments also suggested high consensual validity. In terms of content validity, responses from patient groups indicated that the majority (63.6%) felt it to be a useful measure of patient satisfaction and 70.5% felt all the areas covered were important. Concurrent and criterion validity were also good, with high correlations with existing scales and with those on a section being significantly less satisfied on the PCSQ (F = 13.3, P = 0.0004). Test-retest reliability was adequate (Cohen's κ 0.48–0.80) and the internal consistency of the PCSQ was good, at 0.82 (Cronbach's α). The PCSQ performed well in all aspects of validity and reliability, indicating that it has good psychometric properties and can be a useful tool for measuring patient satisfaction. However, there remains the need to analyse more closely the concept of satisfaction and its determinants.
