Predictive capacity of prodromal symptoms in first-episode psychosis of recent onset

BACKGROUND

Both the nature and number of a wide range of prodromal symptoms have been related to the severity and type of psychopathology in the psychotic phase. However, at present there is an incomplete picture focused mainly on the positive pre-psychotic dimension.

AIM

To characterize the prodromal phase retrospectively, examining the number and nature of prodromal symptoms as well as their relationship with psychopathology at the onset of first-episode psychosis.

METHODS

Retrospective study of 79 patients experiencing a first-episode psychosis of less than 1 year from the onset of full-blown psychosis. All patients were evaluated with a comprehensive battery of instruments including socio-demographic and clinical questionnaire, IRAOS interview, PANSS, stressful life events scale (PERI) and WAIS/WISC (vocabulary subtest). Bivariate associations and multiple regression analysis were performed.

RESULTS

Regression models revealed that several prodromal dimensions of IRAOS (delusions, affect, language, behaviour and non-hallucinatory disturbances of perception) predicted the onset of psychosis, with positive (22.4% of the variance) and disorganized (25.6% of the variance) dimensions being the most widely explained.

CONCLUSION

In addition to attenuated positive symptoms, other symptoms such as affective, behavioural and language disturbances should also be considered in the definitions criteria of at-high-risk people.

Clinical presentation of acute coronary syndrome in HIV infected adults: a retrospective analysis of a prospectively collected cohort

OBJECTIVES

To compare clinical presentation and short-term prognosis of acute coronary syndrome (ACS) in HIV-infected and uninfected adults.

DESIGN

Retrospective analysis of a prospectively collected cohort.

METHODS

HIV-infected patients with myocardial infarction or unstable angina were identified by clinical history and specific characteristics of HIV infection were consecutively registered. Surviving patients were followed for at least one month after discharge. Risk factors for cardiovascular disease, clinical symptoms at admission, type of ACS, delivery of care, and factors associated with prognosis were compared between HIV-infected and uninfected adults.

RESULTS

Among 627 patients included, 44 (7%) were HIV-infected patients. HIV-infected patients were younger, more frequently men, and had higher prevalence of cardiovascular risk factors than uninfected patients. HIV-infected patients persisted frequently with less pain at Emergency Department (ED) (34% vs 82%, P<0.001) and complained of dyspnea (2% vs 15%, P<0.05) persisted in respect to HIV-uninfected patients. ST-elevation myocardial infarction was the most frequent ACS in HIV-infected patients (59% vs 24%) whereas non-ST-elevation myocardial infarction (23% vs 38%) and unstable angina (18% vs 38%) were the predominant ones in uninfected patients (P<0.001). Catheterism was performed more commonly in HIV-infected patients (75% vs 62%, P<0.01) and similarly admitted in the coronary care unit (38% vs 41%, P=0.81). The evolution was similar in both groups. When HIV-infected patients were matched by age and sex with a subgroup of 88 HIV-uninfected patients, most of the differences disappeared.

CONCLUSIONS

HIV-infected adults presenting with ACS are younger and have fewer symptoms than uninfected. Despite having a more established disease, short-term prognosis is similar.

[Schizophrenic patients living in the community. Nursing referral]

The authors describe the clinical and socio-demograpaphic characteristics of schizophrenic patients who live out in the community. The authors study the clinical profile and the disabilities of those items derived from nursing. To do so, the authors made a random selection from persons diagnosed as schizophrenics who visited one of the five Mental Health Centers in the Sant Joan de Déu Hospital network's Mental Health Services. The authors evaluated sociodemographic characteristics, use of services, disabilities based on WHO-DAS, PANSS psychopathology, and LSP ability to function socially. Of the 231 patients included in this study group, 141 patients followed a psychiatrist only treatment program while 90, or 39%, followed a combined psychiatrist-nurse treatment program. Upon comparing these two groups, the authors observed that those patients who followed a combined treatment program had a higher score on the Negative PANSS test (*p < 0.005) which means they have many more difficulties to adequately carry out social functions in daily life activities. On the other hand, this group had lower scores on the WHO-DAS-IV Total test (*p < 0.001), on the WHO-DAS-IV Occupational Test (*p < 0.001), on the WHO-DAS-IV Familiar Test (*p < 0.005) and on WHO-DAS-IV Personal Care Test (*p < 0.005). The authors did not observe any significant results on the rest of the subscales nor on the LSP test.
