RESUMEN
The usefulness of the Sense of Coherence (SOC) scale in the nursing setting is well-established, and an association between SOC and suicidality has been suggested. The aim was to test whether low SOC at index attempt is an independent predictor of suicidality at 2-month follow-up and of risk for repeat attempt. The study, which had a prospective cross-sectional design, included patients admitted to hospital after a suicide attempt. They were interviewed by means of Structured Clinical Interview for DSM-IV. Participants (n=155) completed the SOC scale and the Comprehensive Psychopathological Self-rating Scale for Affective Syndromes. Suicidality was rated with the Suicide Assessment Scale. Instruments were employed again at follow-up. Non-fatal/fatal repetition within 3 years was determined by review of hospital records. Low SOC at baseline predicted high suicidality at follow-up. The association remained after adjustment for major depression and affective symptom burden. Repeat attempts were made by 54 persons. Low baseline SOC was associated with repeat attempt, but the association did not remain after adjustment for major depression and symptom burden. Low SOC ratings could be a marker of risk for high suicidality in the aftermath of a suicide attempt. The SOC scale could be incorporated in nursing assessments of suicide attempters.

PURPOSE: To determine whether the modified version of the Suicide Assessment Scale (SUAS) can be utilised to predict risk of repeat suicidal behaviour. SUBJECTS AND METHODS: Hundred and sixty-five patients aged 18 to 68 years who were admitted to emergency wards after a suicide attempt were interviewed. Follow-up interviews (n=96) were carried out after 2 months. Associations between SUAS scores and repeat attempt (fatal/non-fatal) during the following 3 years were analysed and the instrument's ability to predict repetition was assessed. RESULTS: High SUAS score (>30) was associated with repetition. The ability of the SUAS to correctly predict repeat suicidal behaviour in the entire study group was low (AUC=0.65, 95% CI=0.56-0.74) but better for those (n=42) who reported ongoing psychiatric treatment at follow-up (AUC=0.78, 95% CI 0.63-0.94). Among the latter group, all with baseline SUAS scores >30 made repeats. CONCLUSION: The modified SUAS performed well as a screening instrument in psychiatric patients.

El objetivo de este estudio fue el de determinar qué relación existía entre una pregunta sobre el humor depresivo, incluida en un cuestionario, y el diagnóstico de depresión establecido según los criterios DSM-III-R. Se envió un cuestionario por correo a una muestra de personas con edades comprendidas entre los 57 y 79 años, elegida al azar en la población del Condado de Dalama, en Suecia central. La proporción de respuestas fue del 74,1 per cent (1.328 personas). Todos aquellos individuos que, en el cuestionario, habían admitido estar deprimidos fueron seleccionados para una entrevista, de ellos, 28 aceptaron participar (el 74 per cent de los que habían sido elegidos). En el momento de ser entrevistadas, 21 personas (el 75 per cent) padecían trastornos afectivos según los criterios DSM-III-R o estaban bajo tratamiento debido a su depresión. 12 personas (el 42,9 per cent) padecían depresión mayor o estaban bajo tratamiento. Asimismo, 9 individuos (el 32,1 per cent) padecían distimia. Incluso los niveles moderados de depresión fueron relacionados con una incapacidad funcional. Una sola pregunta sobre el humor depresivo supone un buen punto de referencia y aunque una respuesta afirmativa no puede considerarse como decisiva a la hora de llegar a un diagnóstico, ésta merece un estudio más profundo.

OBJECTIVES: Only a few prospective surveys have been performed to investigate the relationship between sleep complaints and coronary artery disease (CAD) mortality. This study was conducted to determine whether sleep complaints in a middle-aged population predicted total mortality and CAD mortality. DESIGN: A population-based prospective study. Setting. The County of Dalarna, Sweden. SUBJECTS AND METHODS: In 1983, a random sample of 1870 subjects aged 45-65 years responded to a postal questionnaire (response rate 70.2%) including questions about sleep complaints and various diseases. Mortality data for the period 1983-95 were collected, and Cox proportional hazard analyses were used to examine the mortality risks. RESULTS: At 12-year follow-up 165 males (18.2%) and 101 females (10.5%) had died. After adjustment for a wide range of important putative risk factors, difficulties initiating sleep (DIS) were related to CAD death in males [relative risk (RR), 3.1; 95% confidence interval (CI), 1.5-6.3; P < 0.01], but not in females. Short or long sleep duration did not influence risk of CAD mortality or total mortality for either gender. Depression in males increased the risk of death attributed to CAD (RR, 3.0; 95% CI, 1.1-8.4; P < 0.05) and total mortality (RR, 2.2; 95% CI, 1.1-4.5; P < 0.05). CONCLUSION: These results provide evidence that there is an association between difficulties falling asleep and CAD mortality in males.

OBJECTIVE: To assess the prevalence of subjective sleeping complaints by patients with systemic lupus erythematosus (SLE) and to evaluate the correlation between various sleeping complaints and disease activity. METHODS: A standardised sleep questionnaire, The Uppsala Sleep Inventory, was used to investigate the sleeping habits of 30 outpatients with systemic lupus erythematosus (SLE) in comparison to population-based age- and sex-matched controls. RESULTS: Sleep deficit (difference between need of sleep and actual sleeping time) was similar in patients with SLE (0.8 +/- 0.9 hour) and age-matched female controls (0.4 +/- 0.8 hour). However, patients with SLE reported more frequent disturbances due to pain, both when trying to fall asleep (p < 0.01) and during the night (p < 0.01). They also reported frequent awakenings due to headache (p < 0.01) and disturbances due to other vegetative symptoms. Furthermore, the SLE patients were awake for significantly longer periods during the night and they estimated their degree of fatigue as significantly higher than the female controls (p < 0.0001). CONCLUSION: Patients with SLE seem to get a fairly normal amount of sleep, but are frequently disturbed by pain and by various vegetative symptoms, e.g. breathlessness, sweating, and palpitation, which indicate not only pain but also possible involvement of the nervous system. The nervous system may therefore play a role in sleep disturbances reported by patients with SLE.

AIM: Reported sleep quality was examined in relation to anxiety, depression, selected psycho-physiological sleep disturbing symptoms, daytime dysfunctions according to poor sleep, and quality of life 1 year after percutaneous transluminal coronary angioplasty (PTCA). Furthermore, females were compared with age-matched males to examine any differences in sleep quality, psycho-physiological symptoms and quality of life. STUDY DESIGN: A descriptive comparative study. SAMPLE: Twenty-two females, mean age 62.7 (SD 5.7) and 70 men, mean age 60.4 (SD 6.7), were consecutively recruited. METHOD: A mailed questionnaire was distributed, including the Uppsala Sleep Inventory, Spielberger State Anxiety scale, Zung's Self-rating Depression Scale and the Nottingham Health Profile instrument. RESULTS: Forty-six per cent of the patients had a history of myocardial infarction and 40.2% hypertension. Seventy-two per cent of the patients were anxious and 30.4% depressed. Difficulty in getting to sleep was related to intrusive thoughts with increased feelings of anxiety and sensitivity. Difficulty in maintaining sleep was the most common sleep complaint (42.4%) and physical tiredness/fatigue was the greatest consequence of disturbed sleep (51.1%). Those with pain, palpitations or respiratory nocturnal sleep-disturbing symptoms were characterised by shorter sleep duration, emotional distress, cognitive dysfunction, tiredness and reduced quality of life. Greater difficulties initiating sleep and worse health related quality of life were revealed in females compared with aged-matched males. CONCLUSION: Fragmented sleep is a problem partly because of psycho-physiological symptoms 1 year after PTCA, with reduced resilience to stress, increasing vulnerability or diminished coping ability and poorer quality of life.

Associations between sleep and behaviour in 635 children, aged six to eight years, were investigated using parental responses to a sleep habits questionnaire, and to a behavioural screening form, the Strengths and Difficulties Questionnaire (SDQ). Global reports of sleep problems in 4.9% of the children were associated with a total SDQ score indicative of behaviour problems in 36% of the cases. Conversely, 15% of children with behaviour problems had global reports of sleep problems. Associations between specific sleeping features and different dimensions of behaviour and emotions were also explored. Hyperactivity was associated with tossing and turning during sleep, and with sleep walking; conduct problems were related to bedtime resistance; and emotional symptoms were associated with night terrors, difficulty falling asleep and daytime somnolence. Peer problems were associated with somewhat shorter total sleep time. Finally, a total SDQ score indicative of behaviour problems was associated with bedwetting, nightmares, tossing and turning during sleep and sleep walking, as well as with a slightly shorter total sleep time. We conclude that sleep and behaviour problems are associated in children, and that characteristic associations exist between particular sleep disturbances and specific dimensions of behaviour.

BACKGROUND: In various settings, eating disorder symptoms have been linked to physical activity. METHODS: A random sample of 726 females, aged 17-23 years, responded on a self-administered questionnaire. "High level exercisers" (HiEx) were defined as subjects exercising > or =6 sessions/week, > or =1 h/session. "Exercisers with obligatory attitudes" (ObEx) were those obtaining a result above the 95th percentile on a composite score of obligatory exercise items. These groups were compared to controls regarding composite scores of eating disorder symptoms and other symptoms. RESULTS: While HiEx did not, ObEx obtained a significant result at the p<0.001 level regarding the score for body image problems, recurrent weight-reducing attempts, bingeing and post-prandial impulses to vomit. ObEx was also associated with symptoms related to stress and in particular with a high level of general activity coupled with perfectionistic ambitions. CONCLUSIONS: Eating disorder symptoms in young females seem to be associated with obligatory attitudes to exercise rather than with exercise quantity.

UNLABELLED: Sleep habits, sleep problems and subjective depth of sleep among 1413 schoolchildren aged 6.2-10.9 y were examined via a questionnaire, answered by the child and parent together. Total sleep time was approximately 10.5 h, with no difference between the sexes. Of 887 children who reported that they were awoken at night, parents considered that 75% were superficial sleepers and 25% were deep sleepers. The prevalence of frequent insomnia, sleepwalking and daytime sleepiness was 13, 7 and 4%, respectively. Logistic regression analyses indicated that onset insomnia was associated with fear of sleeping alone, bone pains, hypnagogic myoclonias, rhythmic movement disorder, enuresis, nocturia, confusion when awoken at night, nightmares, bodily movements during sleep, interrupted sleep, daytime sleepiness and daytime headache or stomach ache. Somnambulism was associated with rhythmic movement disorder, somniloquy, spontaneous confused arousals, nocturia and confusion when awoken at night. Increased risk of daytime sleepiness was found among children with fear of sleeping alone, onset insomnia, rhythmic movement disorder, spontaneous confused arousals, snoring, confusion when awoken, nightmares, bodily movements during sleep and headache or stomach ache. CONCLUSION: The results support the notion that onset insomnia is a problem with a predominantly psychological and behavioural background, while sleepwalking is a disorder of arousal without major psychological implications. The mechanisms behind daytime sleepiness seem to be multifactorial.

UNLABELLED: The course and psychological correlates of disturbed sleep during middle childhood were investigated using parents' responses to questionnaires. Five specified sleep disturbances were explored in 614 5-8-y-old children, at baseline and at follow-up, 14 +/- 3 mo later. Difficulties falling asleep, in 6.2% of the children at baseline, persisted in 47.4% of the cases at follow-up; night-waking, in 18.6% at baseline, persisted in 45.5%; snoring, in 9.4% at baseline, persisted in 60%; nightmares, in 4.4% at baseline, persisted in 29.6%, and bedwetting, in 6% at baseline, persisted in 46%. Moreover, children with difficulties falling asleep at baseline frequently displayed bedtime resistance and shorter sleep at follow-up, while night-waking at baseline was related to co-sleeping at follow-up. Snoring at baseline was associated with a trend towards restless sleep at follow-up. Nightmares at baseline were related to several other sleep complaints as well as to behavioural difficulties during daytime at follow-up. Bedwetting at baseline was associated with tendencies towards hyperactivity at follow-up. Separate analyses of cases of persisting sleep disturbances showed that persisting difficulties falling asleep were associated with a need to remedy sleep problems, while persisting nightmares were strongly related to reports suggesting behavioural and emotional problems. CONCLUSION: During middle childhood, difficulties falling asleep, night-waking, snoring, nightmares or bedwetting commonly persist over the course of a year. Persistent nightmares frequently indicate significant psychological problems in affected children.

OBJECTIVE: To study the sleep pattern in ankylosing spondylitis, and to investigate gender differences in sleep, pain, and fatigue. METHODS: Forty-three male and 27 female patients with ankylosing spondylitis completed a sleep questionnaire and the results were compared with earlier findings in 3,558 persons randomly selected from the general population. RESULTS: Too little sleep was reported by 80.8% of the female and 50.0% of the male patients, compared to 28.8% and 21.8% respectively in the reference group (p<0.0001). The main reason was pain in the pre-sleep and sleep-periods (p<0.0001). Daytime fatigue was a major problem (p<0.0001). Higher correlation was found between pain and daytime fatigue than between sleep disturbance and daytime fatigue. CONCLUSION: Sleep disturbance is a significant problem in ankylosing spondylitis. The disturbance is closely related to pain at bedtime and during the night. Gender differences exist in the subjective sleep disturbance, fatigue, and pain.

The purpose of the study was to investigate the natural history of insomnia and its association with depression and mortality. In 1983, 1,870 randomly selected subjects aged 45-65 years answered a questionnaire on sleep and health. Of the 1,604 survivors in 1995, 1,244 (77.6%) answered a new questionnaire with almost identical questions. Mortality data were collected for the 266 subjects that had died during the follow-up period. Chronic insomnia was reported by 36.0% of women and 25.4% of men (chi2 = 9.7; p < .01). About 75% of subjects with insomnia at baseline continued to have insomnia at follow-up. Insomnia in women predicted subsequent depression (odds ratio [OR] = 4.1; 95% confidence interval [CI] 2.1-7.2) but was not related to mortality. In men, insomnia predicted mortality (OR = 1.7; 95% CI 1.2-2.3), but after adjustment for an array of possible risk factors, this association was no longer significant. Men with depression at baseline had an adjusted total death rate that was 1.9 times higher than in the nondepressed men (95% CI: 1.2-3.0).

OBJECTIVES: To evaluate quality of life and psychological symptoms in patients with primary Sjögren's syndrome and to compare this with patients with rheumatoid arthritis. METHODS: A standardised questionnaire, the Psychological General Well-Being Index (PGWB), was used to examine the quality of life and psychological symptoms in patients with primary Sjögren's syndrome (pSS; n = 34). Patients with rheumatoid arthritis (RA; n = 32) were used as patient controls. RESULTS: The total mean score +/- SD for PGWB was 84.9 +/- 16.2 in pSS patients and significantly lower (p = 0.001) than in RA patients (97.7 +/- 17.5). Patients with pSS had an increased propensity for depressed mood (p = 0.0009), and suffered from reduced well-being (p = 0.002) and impaired vitality (p = 0.003). CONCLUSION: The results suggest that patients with pSS have a reduced quality of life, a higher degree of distress and a lower sense of well-being than patients with RA.

OBJECTIVE: To assess the potential pharmacokinetic and pharmacodynamic interaction of zaleplon and thioridazine administered concomitantly in healthy volunteers. METHODS: A three-period, double-blind, randomized crossover study of the psychomotor effects of single oral doses of zaleplon 20 mg alone, thioridazine 50 mg alone, or the two drugs administered concomitantly was performed in 12 healthy subjects. Pharmacodynamic testing was performed before, and at 1, 2, 4, and 8 h after drug administration. Critical flicker fusion (CFF), tapping rate (TR), reaction time (RT) with dominant and nondominant hands, and digit symbol substitution test (DSST) were used to assess psychomotor performance. RESULTS: Pharmacokinetic results showed that coadministration of zaleplon and thioridazine did not alter the pharmacokinetic profile of either drug. In both CFF and TR tests, values for change from baseline with combined treatment were not significantly different from those with thioridazine at any time point, indicating no pharmacodynamic interaction. RT test values with coadministered treatment were significantly different from those with thioridazine alone at 1 h after administration, indicating additivity. Supra-additivity was observed in DSST results at 1, 2, and 4 h. There was no interaction at 8 h. CONCLUSION: The results of single-dose administration showed an additive pharmacodynamic interaction between zaleplon and thioridazine at 1 h in one of four tests and supra-additivity for 4 h in another test. This interaction is relatively short in duration due to the short half-life of zaleplon.

OBJECTIVE: To examine the degree of anxiety and depression and to assess well being and general symptoms in patients with primary Sjögren's syndrome (SS). METHODS: A standardized questionnaire, the Hospital Anxiety and Depression Scale, was used to examine the degree of anxiety and depression in patients with primary SS (n = 62) and in age matched healthy female controls. The Gothenburg quality of life instrument (GQOL) was used to assess well being and general symptoms. Patients with rheumatoid arthritis (RA; n = 38) were used as patient controls. RESULTS: The patients with primary SS had significantly higher scoring rate for "possible" clinical anxiety (48%) and for "possible" clinical depression (32%) compared with reference groups (p<0.05). The physical and mental well being of the patients with primary SS were significantly reduced compared with controls. Furthermore, patients with primary SS complained more commonly of low mood, irritability, headache, gastrointestinal symptoms, and impaired concentration and memory than the patients with RA. CONCLUSION: The results indicate that patients with primary SS often have psychiatric symptoms and worse well being, which may affect their quality of life.

Nocturnal urinary continence is dependent on 3 factors: 1) nocturnal urine production, 2) nocturnal bladder function and 3) sleep and arousal mechanisms. Any child will suffer from nocturnal enuresis if more urine is produced than can be contained in the bladder or if the detrusor is hyperactive, provided that he or she is not awakened by the imminent bladder contraction. Urine production is regulated by fluid intake and several interrelated renal, hormonal and neural factors, foremost of which are vasopressin, renin, angiotensin and the sympathetic nervous system. Detrusor function is governed by the autonomic nervous system which under ideal conditions is under central nervous control. Arousal from sleep is dependent on the reticular activating system, a diffuse neural network that translates sensory input into arousal stimuli via brain stem noradrenergic neurons. Disturbances in nocturnal urine production, bladder function and arousal mechanisms have all been firmly implicated as pathogenetic factors in nocturnal enuresis. The group of enuretic children are, however, pathogenetically heterogeneous, and two main types can be discerned: 1) Diuresis-dependent enuresis - these children void because of excessive nocturnal urine production and impaired arousal mechanisms. 2) Detrusor-dependent enuresis - these children void because of nocturnal detrusor hyperactivity and impaired arousal mechanisms. The main clinical difference between the two groups is that desmopressin is usually effective in the former but not in the latter. There are two first-line therapies in nocturnal enuresis: the enuresis alarm and desmopressin medication. Promising second-line treatments include anticholinergic drugs, urotherapy and treatment of occult constipation.

Four patients affected with autosomal dominant cerebellar ataxia, deafness, and narcolepsy underwent brain CT and MRI. Radiologic findings were supratentorial atrophy (more pronounced than infratentorial atrophy), pronounced dilatation of the third ventricle, low T2 signal intensity in the basal ganglia, loss of cerebral cortex-white matter differentiation, and periventricular high-signal rims. 2-[18F]Fluoro-2-deoxy-D-glucose PET was done with one patient, without specific findings. Genetic analyses excluded SCA-1, SCA-2, SCA-3, SCA-6, SCA-7, DRPLA, and huntingtin gene mutations.

Parents' reports on 1844 five to seven year olds from the general population were used to provide a detailed update about prevalence and correlates of sleep disturbances in children. Five different sleep disturbances were focused on: difficulty falling asleep, reported in 5.6% of the children; night waking in 15.5%; snoring in 7.7%; nightmares in 3.1%, and bedwetting in 5.3% of the children. Coexisting sleep disturbances were frequent in children with difficulties falling asleep, night waking and nightmares, but bedwetting usually emerged as a singular sleep disturbance. Nightmares were associated with serious health problems or handicaps, sleep problems in conjunction with life events, and female gender. Snoring as well as bedwetting were associated with reports of "very active" children. In 6.7% of the total sample, parents had previously consulted the healthcare services for a sleep problem in their child. These children had reports of colic during infancy, eczema, serious health problems or handicaps, current snoring and current nightmares. Only 1.1% (n = 21) of the children were said to have a present need to remedy sleep problems. The reports on these children included coexisting sleep disturbances, previous consultations for sleeping problems, parents' perceptions of "very active" children, diagnoses of attention deficit hyperactivity disorder, and major life events which had triggered sleep problems. In conclusion, although sleep disturbances are common in 5-7-y-old children, parents seldom express a need to remedy sleep problems in their children of this age.

In order to evaluate differences in sleep factors between children with wetting problems and dry children, questionnaire data were obtained from 1,413 schoolchildren between the ages of 6 and 10 y. The analyses were performed using logistic regression, and adjusted odds ratios (ORs) were calculated to approximate the relative risk. Current enuresis was associated with a subjectively high arousal threshold, pavor nocturnus, nocturia and confusion when awoken from sleep (ORs 2.7, 2.4, 2.1 and 3.4, respectively), whereas children with current incontinence often experienced bedtime fears, onset insomnia or nocturia (ORs 2.4, 2.3 and 2.7, respectively). Children exhibiting urinary urgency were overrepresented among both children with current enuresis (OR 2.5) and those with current incontinence (OR 17.2). It is concluded that impaired arousal mechanisms and bladder instability are aetiological factors underlying nocturnal enuresis.
