Background: While several studies have noted smell impairment in schizophrenia, it is unclear whether this impairment extends to acute psychosis and whether it is associated with more severe illness as expressed in extended hospitalization.

Objectives: To evaluate the olfactory function of patients in an acute psychotic state and correlate it with clinical symptomatology and length of hospitalization.

Methods: Olfactory function was assessed in 20 patients with schizophrenia in their first week of hospital admission for acute psychosis compared with matched controls. Olfaction was evaluated via three stages: threshold, discrimination, and identification of different odors utilizing the Sniffin' Sticks test battery.

Results: Schizophrenia patients scored significantly lower on total smell score, discrimination, and identification abilities. A significant association was observed between hospitalization duration and total smell score and smell discrimination. No significant associations between smell and clinical symptomatology were observed.

Conclusions: Study observations confirm impaired sense of smell in schizophrenia patients and suggest that smell impairment may be a potential marker of more serious illness as expressed in longer hospital stay.

Background: Although exercise has been shown to improve mood and well-being, the precise mechanism remains unknown. Neurosteroids are important neuroactive molecules with demonstrated involvement in several neurophysiological and disease processes. Previous research has noted neurosteroid changes in dehydroepiandrosterone (DHEA) levels following exercise.



Objectives: To determine whether changes in DHEA levels are associated with mood improvement after exercise and whether there are any differences in the effects on younger and older individuals. 



Methods: Individuals ≤ 50 years of age or > 65 years of age were recruited for study participation. Before and after 30 minutes of a standardized cycling regimen, each patient provided a blood sample and completed a questionnaire on mood and well-being. 



Results: Findings confirmed a significant increase in DHEA levels post-exercise. A decrease in negative factors (fatigue, tension, depression, anger) and an increase in positive mood factors were noted. No difference in change of measures was noted between younger and older subjects. A positive correlation was noted between mood change and DHEA blood-level changes in older subjects. Among older males, DHEA appeared to be associated with mood change after exercise. 



Conclusions: While preliminary, findings indicate a possible association between mood improvement following exercise and DHEA blood level changes. Understanding the biological mechanisms of exercise-induced mood changes is critical to utilizing exercise as a treatment for mood disorders.

Background: In criminal law, psychiatrists are consulted regarding the "insanity defense" and the defendant's competency to stand trial. Court-ordered hospital admissions for such evaluations are on the increase, creating a major burden on the health system.

Objectives: To assess, in a hospital setting, whether hospitalization of the defendant is necessary for conducting a psychiatric evaluation.

Methods: A 6 month prospective observational study exploring the phenomenon was conducted at the Beer Yaakov Mental Health Center. The psychiatrist was asked both at the initiation and again at the end of the assessment process whether the subject was competent to stand trial and responsible for his/her actions and if hospitalization was necessary in order to conduct the evaluation. 

Results: During the study period there were 112 admissions with a court request for a psychiatric evaluation. In 73 of the cases (65.2%) the evaluating psychiatrist believed there was no need for hospitalization. This assessment did not change by the end of the hospitalization in all cases. Employment and alcohol use were the only factors associated with a lower need for hospitalization (OR 0.24, 95%CI 0.07–0.77, and 0.34, 95%CI 0.13–0.90, respectively).

Conclusions: In the majority of cases, based on the evaluating psychiatrist's responses, the evaluation could have been conducted without need for hospitalization. The findings indicate that an outpatient unit designated to write court-requested psychiatric evaluations could significantly reduce the rates of hospital admissions for this purpose.

 

Background: Analysis of the trends in psychiatric admissions and discharges is necessary to correctly plan and distribute resources, especially given the current international climate of “deinstitutionalization." Israel, too, is implementing “reform” in the national psychiatric system – to transfer psychiatric treatment from a hospital to a community setting

Objectives: To analyze admission and discharge patterns, explore trends in psychiatric hospital length of stay, and compare these characteristics between first-episode and chronic patients, between children, youth and adults, and between hospitals.

Methods: All admissions and discharges from inpatient psychiatric wards between the years 2000 and 2004 were analyzed and characterized according to age, length of hospitalization, legal status, and nature of admitting institution (state hospital, health fund, general hospital).

Results: Mean length of stay in adults decreased during the 5 year study period, from 37.6 days in 2000 to 36.4 days in 2004. In years with higher admissions, hospital stay was shorter (P < 0.05). Length of stay in psychiatric wards in general hospitals was shorter than in state hospitals (P < 0.001). In contrast to adults and children, length of stay among adolescents showed a gradual increase (P < 0.05). Involuntary hospitalization comprised 25.3% of all admissions, and 16.8% of discharged patients were readmitted within 30 days. A dramatic decrease (24.3%) in the number of chronic hospitalizations was noted.

Conclusions: Various factors may account for these developments. Protracted hospitalizations may be reduced through changes in various aspects of treatment planning and psychiatric care continuum. The decrease in number of admissions, length of stay and number of chronically admitted patients remains in line with international practices. Particular attention needs to be devoted to planning and funding so that availability of community services matches reduction in psychiatric hospitalization.
