Risk factors for asthma in young adults. Spanish Group of the European Community Respiratory Health Survey

We assessed the association of asthma prevalence in young adults with susceptibility factors and environmental exposures, taking into account the age at asthma onset. A random sample of the general population, aged 20-44 yrs, in five areas of Spain (Albacete, Barcelona, Galdakao, Huelva, and Oviedo) was selected in the frame of the European Community Respiratory Health Survey (ECRHS). Overall, 2,646 subjects (response rate = 60.9%) responded to a respiratory questionnaire and 1,797 (41.4%) finalized a bronchial challenge. Atopy to perennial (odds ratio (OR) = 10.2, 95% confidence interval 4.2-25) and seasonal allergens (11.5, 4.6-28), parental asthma (4.5, 2.5-8.4), and birth order (OR for no older siblings in comparison to having more than two = 3.2, 1.2-9.1) were associated with current asthma whatever the age of asthma onset. Past asthma was associated to a lesser extent with atopy (OR around 3.5 to both perennial and seasonal allergens). Lower respiratory tract infections before the age of 5 yrs (LRTI), having had a pet in childhood, and being born in a younger cohort were associated with asthma starting before the age of 15 yrs, but not after. Male gender was more frequent in childhood asthma and female gender in adulthood. In addition to the known risk factors of asthma (atopy to perennial allergens, parental asthma) we provide evidence for an association of asthma (whatever the age of onset) with sensitization to seasonal allergens, and having less than three older siblings; and for an association of childhood asthma with lower respiratory tract infections.     

Prevalence of obesity in Spain: the SEEDO''97 study. Spanish Collaborative Group for the Study of Obesity

BACKGROUND: Multiple viral subpopulations coexist in an HIV infected patient with dynamics of selection established between them. In order to get insight on the phenotype of these subpoblations, and its relation with disease progression, we have studied the biological variability of HIV-1 in 113 patients. Variability was related with CD4+ T lymphocyte counts, clinical status, way of viral transmission and antiretroviral treatment. PATIENTS AND METHODS: 113 patients (80 adults and 33 children) were studied for HIV-1 isolation in cocultures of infected and non infected lymphocytes. Viral replication was evaluated as rapid (R)/slow (S) or high (H)/low (L). Syncytia formation was estimated in MT2 cell line (SI/NSI). The tropism toward lymphocytes and monocytes (LM) was studied on H9 and U937 cell lines. RESULTS: Up to 86.7% of viral isolates were R, 56.6% were H and 49.6% were SI. These percentages increased with disease progression. Eight viral strains were R/H/NSI cocultivated in MT2 cells and SI in cocultured lymphocytes (NSI/SI), which may be considered as a new phenotype. All the SI isolates and all the R/H (SI and NSI) isolates were LM. Three categories were established: R/H/SI/LM, R/H/NSI/LM and S/L/NSI/NLM. The first two categories corresponded to patients with CD4+ T lymphocytes <200 x 10(6)/I (56%, 50%). The third category corresponded to patients with > 500 x 10(6)/I (53.3%). CONCLUSIONS: Viral replication and SI phenotype, independently, are useful markers for severity of HIV infection. The biological differences among NSI of the 3 viral phenotype categories, including the new subgroup NSI/SI, may indicate the existence of more pathogenic NSI subpopulations.     

Epidemiological study on the incidence of inflammatory bowel disease in 4 Spanish areas. Spanish Group on the Epidemiological Study of Inflammatory Bowel Disease

BACKGROUND: The incidence of inflammatory bowel disease (IBD) shows marked geographical variations. The aim of this study was to determine and compare the incidence of IBD in four Spanish areas: Sabadell (Northeast), Vigo (Northwest), Mallorca island and Motril (South). PATIENTS AND METHODS: Prospective survey based on inception cohorts over a two-years period (1 October 1991 to September 1993). Subjects were the patients resident in these areas and diagnosed of IBD according to a standard protocol for case ascertainment and definition. RESULTS: Altogether 328 cases were identified, of whom 191 were diagnosed as ulcerative colitis (UC), 135 as Crohn's disease (CD) and 2 as indeterminate colitis. The overall adjusted incidence rate per 100,000 persons between ages 15-64 years of UC and CD were respectively 9.8 and 5.2 in Sabadell, 7.7 and 5.0 in Vigo, 7.8 and 5.8 in Mallorca and 4.3 and 6.5 in Motril. The Incidence rate ratio showed no significant differences for either conditions among these areas. The global adjusted incidence rate of UC in Spanish areas (8.0; IC 95%: 6.3-9.7) was significantly lower to that of Northern European countries while that of CD (5.5; IC 95%: 4.1-6.9) was between that of Northern and Southern Europe with no significant differences. CONCLUSIONS: The incidence of IBD did not show differences among the Spanish areas, and rates are between 2 and 6 times higher than those previously reported. The incidence of UC is significantly lower than that observed in the North of Europe, while for CD the incidence is between that of Northern and Southern Europe.     

Prevalence of wheeze and asthma and relation to atopy in urban and rural Ethiopia

BACKGROUND: Asthma and allergy in developing countries may be associated with adoption of an urbanised "western" lifestyle. We compared the rates of asthma symptoms and atopy in urban populations in Jimma, southwest Ethiopia, at an early stage of economic development with those among the population of remote, rural, subsistence areas, and assessed the potential role of environmental aetiological factors leading to the differences. METHODS: Information on wheeze of 12 months' duration, diagnosed asthma, and cough for 3 months of the year was gathered by questionnaire in random household samples of 9844 people from urban Jimma and of 3032 from rural areas. Atopy was defined by allergen skin-test response to Dermatophagoides pteronyssinus and mixed threshings measured in a one-in-four subsample of those aged 5 years and older from both groups. FINDINGS: All respiratory symptoms were rare in children and were significantly less common overall in the rural than in urban group (wheeze odds ratio 0.31 [95% CI 0.22-0.43], p < 0.0001). Asthma was reported by 351 (3.6%) of the urban group, with a median reported duration of 8.5 years (IQR 4-17 years) that was unrelated to age. Atopy was a strong risk factor for asthma in urban Jimma. In the rural areas, skin sensitivity to mixed threshings was only slightly less common than in urban Jimma (0.67 [0.40-1.12], p = 0.13), whereas sensitivity to D pteronyssinus was significantly more common (3.24 [2.40-4.38], p < 0.0001), and since none of the 119 atopic individuals in the rural area reported wheeze or asthma, atopy was possibly associated with a reduction in the risk of disease among this group. Wheeze or D pteronyssinus sensitivity were positively associated with housing style, bedding materials, and use of malathion insecticide, but no single factor accounted for the urban-rural differences. INTERPRETATION: Wheeze and asthma are especially rare in rural subsistence areas, and atopy may be associated with a reduced prevalence of these symptoms in this environment. In urban Jimma, self-reported asthma seemed to emerge as a clinical problem about 10 years before our study began, which is consistent with an effect of new environmental exposures. The factor or factors leading to the increase in asthma and allergy have not been identified, although exposures related to general changes in the domestic environment are likely to be involved.     

The prevalence of clinical diabetic polyneuropathy in Spain: a study in primary care and hospital clinic groups. Neuropathy Spanish Study Group of the Spanish Diabetes Society (SDS)

A multiregional cross-sectional study of clinical diabetic polyneuropathy (DPN) was carried out among Spanish diabetes patients using a standard system for scoring symptoms and signs of polyneuropathy. The main patient sample comprised 2644 patients (54.7% women) aged 15-74 years (mean 57.2 +/- 0.3 years), 86.9% of whom had Type II (non-insulin-dependent) diabetes mellitus and 29.4% were attending hospital clinics. Mean duration of diabetes since diagnosis was 10.2 +/- 0.2 years. The prevalence of DPN was 22.7% (95% confidence interval 21.2-24.3%) in the whole sample, 12.9% (9.4-16.5%) among patients with Type I (insulin-dependent) diabetes mellitus and 24.1% (22.4-25.9%) among patients with Type II diabetes; there was no significant difference in prevalence between men and women. Prevalence increased with age (from < 5% in the 15- to 19-year-old age group to 29.5% in the 70- to 74-year-old group) and with duration of diabetes since diagnosis (from 14.2% among those with duration < 5 years to 44.2% among those with duration > 30 years). In a supplementary sample of 161 diabetic patients aged 75 to 79 years (excluded from the main sample to prevent confusion between diabetes-induced and ageing-induced neuropathies), prevalence was 37.8%. Ninety-three patients (3.3%) had or had had foot ulcers and 21 of these 93 (0.7%) had undergone amputation; 90.8% of ulcerated patients had Type II diabetes, and 54% had DPN (in most cases with loss of perception of vibration), as against a prevalence of DPN of 19.9% among patients without ulcers. We conclude that nearly a quarter of Spanish diabetic patients have DPN; that over 90% of DPN patients have Type II diabetes; that the prevalence of DPN increases with age and with the duration of the disease, and that the risk of foot ulcers among DPN patients is about three times the risk among diabetic patients without DPN. We accordingly emphasize the responsibility of primary care physicians to try to prevent diabetic foot lesions by early diagnosis of DPN.     

Prognostic factors and etiology in patients with severe community-acquired pneumonia admitted at the ICU. Spanish multicenter study. Study Group on Severe Community-Acquired Pneumonia in Spain

OBJECTIVE: To determine the techniques used for the etiological diagnosis of community-acquired pneumonia in patients admitted to the intensive care unit (ICU) and to describe the predominant causative organisms as well as prognostic factors of ICU mortality. PATIENTS AND METHODS: A total of 262 patients with community-acquired pneumonia admitted to 26 ICUs between 1 November of 1991 and 31 October of 1992 were included in a prospective, open, multicenter study. RESULTS: The diagnostic techniques most frequently used were blood culture (243 cases) and simple tracheal aspirate (166 cases). Simple tracheal aspirate (58.4%), bronchoalveolar lavage (47.7%), and protected-specimen brush (44.2%) were the techniques that showed the highest diagnostic reliability. In 220 cases, techniques considered of high diagnostic probability were employed. With the use of these procedures, the most frequent causative pathogens were Streptococcus pneumoniae (13.6%) and Legionella pneumophila (9.5%). In 100 cases (45.5%), no pathogen was isolated. A total of 88 patients (33.6%) died during the ICU stay. Predictive variables of poor outcome selected by means of a multivariate analysis were as follows: multisystemic failure (OR = 28.6; 95% CI: 12.8-65.1; p = 0.0001), APACHE II at the time of ICU admission (OR = 5.3; 95% CI: 2.5-11.3; p = 0.0001), progression and/or spread of lung infection (OR = 4.5; 95% CI: 2.4-8.4; p = 0.0001), and shock on admission (OR = 8.48; 95% CI: 4.5-15.9; p = 0.0001). CONCLUSIONS: In 45.5% of patients with community-acquired pneumonia admitted to ICU, no causative pathogen was identified. The prognosis of these patients was influenced by the severity of disease assessed by APACHE II score and presence of multisystemic failure and shock at the time of ICU admission.     

Increased prevalence of sleep disturbances and daytime sleepiness in subjects with bronchial asthma: a population study of young adults in three European countries

The aim of this study was to investigate whether asthma is associated with decreased quality of sleep and increased daytime sleepiness. The study involved a random population of 2,202 subjects supplemented by 459 subjects with suspected asthma, aged 20-45 yrs. The subjects were from Reykjavik (Iceland), Uppsala and G?teborg (Sweden) and Antwerp (Belgium), and participated in the European Community Respiratory Health Survey. The investigation included a structured interview, methacholine challenge, skinprick tests and a questionnaire on sleep disturbances. Participants in Iceland and Sweden also estimated their sleep times and made peak expiratory flow (PEF) recordings during a period of 1 week. Asthma was defined as self-reported physician-diagnosed asthma with current asthma-related symptoms (n = 267). Difficulties inducing sleep (DIS) and early morning awakenings (EMA) were about twice as common, and daytime sleepiness 50% more common, in asthmatics compared with subjects without asthma. After adjusting for possible confounders, a positive association was found between asthma and: DIS (odds ratio (OR) = 1.8); EMA (OR = 2.0); daytime sleepiness (OR = 1.6); snoring (OR = 1.7); and self reported apnoeas (OR = 3.7). Allergic rhinitis, which was reported by 71% of subjects with asthma, was independently related to DIS (OR = 2.0) and daytime sleepiness (OR = 1.3). A significant correlation was found between the number of asthma-related symptoms and sleep disturbances (p < 0.001). Asthma is associated with decreased subjective quality of sleep and increased daytime sleepiness. Concurrent allergic rhinitis may be an important underlying cause of sleep impairment in asthmatic patients.     

Montelukast, a potent leukotriene receptor antagonist, causes dose-related improvements in chronic asthma. Montelukast Asthma Study Group

The leukotrienes are known to be important mediators of bronchial asthma. The ability of montelukast, a potent and selective CysLT1 leukotriene receptor antagonist, to cause a dose-related improvement in chronic asthma was investigated in a placebo-controlled, multicentre, parallel-group study. After a two week placebo run-in period, chronic asthmatic patients with a forced expiratory volume in one second (FEV1) 40-80% predicted with > or = 15% increase (absolute value) after beta2-agonist were randomly assigned to one of four treatment groups (placebo or montelukast 2, 10, or 50 mg once daily in the evening) for a three week, double-blind treatment period. For patient-reported end-points (daytime symptom score, use of as needed inhaled beta2 agonist, asthma-specific quality of life) and frequency of asthma exacerbations, montelukast 10 and 50 mg caused similar responses, superior to 2 mg and significantly (p<0.05; linear trend test) different from placebo. All three doses caused improvements in FEV1 and morning and evening peak expiratory flow rate (PEFR) that were significantly (p<0.05) different from placebo. Differences (least square mean) between the pooled 10 and 50 mg montelukast treatment groups and placebo were: 7.1% change from baseline in FEV1, 19.23 L x min(-1) in morning PEFR, -0.29 in daytime asthma symptom score (absolute value), and -0.82 in beta2-agonist use (puff x day(-1)). The incidence of adverse experiences was neither dose-related nor different between montelukast and placebo treatments. We conclude that montelukast causes a dose-related improvement in patient-reported asthma end-points over the range 2-50 mg. Montelukast causes benefit to chronic asthmatic patients by improving asthma control end-points.     

Pneumonia after heart transplantation: a multi-institutional study. Spanish Transplantation Infection Study Group

Matrix metalloproteinases (MMPs) are involved in connective tissue turnover under physiological and pathological conditions. MMP activity is regulated by the requirement for zymogen activation. This report describes a proMMP-3 activator produced by articular cartilage. The activator initiates a step-wise processing of proMMP-3 to generate an array of active species. Sequencing of activation intermediates demonstrated cleavage on the NH2-terminal side of certain basic residues in the MMP-3 propeptide. Metal ion chelators inhibited activator-dependent proteolysis, and activity was restored by low levels of ZnCl2. These catalytic properties suggest similarity to members of the insulinase superfamily of metalloendopeptidases with in vitro specificity for single arginine or paired basic processing sites in a variety of prohormones. Dibasic sites also exist in the propeptides of several MMPs including proMMP-3. This is the first report that cartilage produces a potent MMP proenzyme activator, opening the possibility of a novel intrinsic activation pathway for catabolic processes in this avascular tissue.     

Oral glucocorticosteroid-sparing effect of budesonide administered by Turbuhaler: a double-blind, placebo-controlled study in adults with moderate-to-severe chronic asthma. Pulmicort Turbuhaler Study Group

The purpose of this study was to evaluate the correlation between alteration in telomere length and prognosis in patients with pathological stage I-II non-small cell lung cancer. We measured telomeric repeat length and telomerase activity by use of southern blot analysis of terminal restriction fragments and a non-radioactive ELISA-based assay, respectively. RESULTS: Alterations in TRF lengths were present in 17(29.8%) of 57 patients. Patients with altered TRF length had significantly shorter survival than did patients without (P = 0.0051). In multivariate analysis, only alteration in TRF length independently correlated with shortened survival (P = 0.0033).     

Evaluation of efficacy of traditional Chinese medicines in the treatment of childhood bronchial asthma: clinical trial, immunological tests and animal study. Taiwan Asthma Study Group

Traditional Chinese medicines (TCM) have been used to treat bronchial asthma for several centuries and a certain degree of clinical benefit has been observed; however, scientific substantiation is lacking. A multicenter, double-blind and placebo-controlled study was therefore conducted to evaluate the clinical efficacy in terms of symptom score, medication score, morning and evening PEFRs, and changes of immunoregulatory function, such as distribution of lymphocyte subsets and in vivo and in vitro production of lymphokines (IFN-gamma and IL-4) and inflammatory mediators (histamine, PGE2 and LTC4). Furthermore, the protective effect of TCM on the late asthmatic reaction (LAR) was evaluated by using asthmatic guinea pigs. Three hundred and three asthmatic children were classified by Chinese doctors, according to a standardized questionnaire designed on the basis of basic logic of Chinese medicine, into three groups of specific constitution (group A, B and C). Group A consisted of 32 herb A-treated patients and 34 placebo-treated; group B, 74 herb B-treated and 64 placebo-treated; and group C, 55 herb C-treated and 44 placebo-treated. The study period was six months. The results were: 1) Both treatment group and placebo group showed an improvement in all clinical parameters, thus demonstrating a placebo effect. However, the improvement was usually greater in the former than the latter, although only the difference in PEFR was significant; 2) Herb A could increase total T cell and decrease B cell; 3) Herb A and B enhanced production of PGE2 but not LTC4, IFN-gamma and IL-4; 4) There was a general tendency for in vivo and in vitro production of histamine to decrease at the end of study in both treatment group and placebo group; however, the decrease was significantly greater in the former than the latter; 5) In asthmatic guinea pigs, 10-day's pretreatment with Chinese herbs could reverse the decrease of sGaw, suppress eosinophilia in bronchoalveolar lavage fluid (BALF), prevent the eosinophil infiltration of airways, increase PGE2 production and decrease LTC4 production in serum and BALF. Thus, traditional Chinese medicines did show a certain degree of clinical efficacy. The decreased production of histamine and LTC4, increased production of PGE2 that were found in both asthmatic children and asthmatic guinea pigs, and prevention of occurrence of LAR by suppressing eosinophil infiltration of airways and preserving airway conductance that were observed in asthmatic guinea pigs after allergen challenge might be used to account partly for the effectiveness.     

Clinical characteristics of type I Gaucher's disease in Spain. Preliminary results of national survey. Spanish Group on Gaucher's Disease

BACKGROUND: To know the incidence and distribution of Gauchers's disease (GD) in Spain, a national inquiry was carried out in order to analyze the clinical, genetic and evolutive features of these patients. PATIENTS AND METHODS: A questionnaire including demographic, clinical, diagnostic, biological, radiological and evolutive data was sent to the hospitals. Each case with a presumptive diagnosis was considered a "censored patient". The cases without enzymatic or genetic diagnosis were studied in a reference laboratory (the same for all the samples). The Zimran's Severity index was employed to evaluate the clinical status. The enzymatic activity of acid beta-glucosidase was studied in cellular extracts of peripheral blood granulocytes by a fluorescent method using an artificial substrate (methyl-umbeliferyl-beta-deglycoside). The characterization of the mutations of the glucosidase gene was determined by PCR molecular analysis in the samples of DNA studying the mutations: N370S, L444P, 84GG and IVS2+1. RESULTS: Seventy five patients were censored; in 48 the inquiry was completed. These patients belonged to 54 families. The mean age at diagnosis was 24.7 years, being the M/F distribution 16/32. The illness was asymptomatic in 13.3%, visceral disease was present in 83.3% of patients and bone disease in 70.8%. The 45.8% of patients had hemoglobin levels < 110 g/l, 35.4% low leucocyte count < 4,0 x 10(9)/l and 77.0% low platelet count < 150 x 10(9)/l. High acid phosphatase levels were observed in 100% of cases and in 34.7% biochemical hepatic dysfunction was observed. The test for acid glucosidase showed a marked decrease in enzymatic activity. In 71% of the patients morphologic documentation (splenic or hepatic tissue, bone marrow biopsy or aspirates) was performed. The most frequent mutations observed were N370S (47.7% of the alleles detected), and L444P (24.4%). In 18.7% of the cases the disease was stable or slightly progressive, in 27.0% the spleen was removed between 1-14 years of the being made and 45.8% were put onto an alglucerase trial. CONCLUSIONS: The incidence of GD in Spain is at present lower that the previously reported for other european countries. The clinical features are not different except in the case of bone disease, less frequent in our cases, probably limited by the absence of MR. The pattern of distribution of mutation is also similar.     

Birth characteristics and asthma symptoms in young adults: results from a population-based cohort study in Norway

There is evidence that the origin of obstructive lung disease may be traced back to foetal life. The associations between birth characteristics and asthma symptoms were studied in a random population sample of young Norwegian adults. Respiratory symptoms were recorded in a population-based questionnaire survey. The records of all subjects aged 20-24 yrs were linked with the Medical Birth Registry of Norway. Of 868 subjects born in Norway, there were 690 (79%) responders. The associations between asthma symptoms and birth characteristics were analysed by logistic regression, adjusted for possible confounding factors. Asthma symptoms in young adults were inversely associated with birth weight (odds ratio (OR)wheeze=0.82; 95% confidence interval (CI)=0.69-0.96x500 g increase in birth weight(-1))), and after adjustment for gestational age, birth length, parity and maternal age (ORwheeze=0.69; 95% CI=0.50-0.95x500 g increase in birth weight(-1)). The association did not vary according to adult smoking habits or atopic status and remained when premature and low weight births were excluded (ORwheeze=0.73; 95% CI=0.60-0.90x500 g increase in birth weight(-1)). The association was consistent for all asthma symptoms. Adjusted for birth weight, asthma symptoms were further associated with low gestational age, high birth length and low maternal age. In a random sample of young adults, asthma symptoms were strongly associated with low birth weight, an association driven by the full-term births within the normal birth weight range. The findings show that the risk for adult asthma is partly established early in life and suggest that poor intrauterine growth is involved in the aetiology of asthma.     

Prevalence of mental disorders and psychosocial impairments in adolescents and young adults

Graves' disease is the predominant cause of hyperthyroidism in the pediatric age group. Other disorders must be recognized, however, because adequate management relies on a precise diagnosis. Careful monitoring of the thyroid status is required during this active phase of growth and development.     

Once-daily sparfloxacin versus high-dosage amoxicillin in the treatment of community-acquired, suspected pneumococcal pneumonia in adults. Sparfloxacin European Study Group

The objective of this randomized, double-blind, multicenter study of 329 adult patients requiring hospitalization was to compare the safety and efficacy of sparfloxacin at a dosage of 200 mg once daily (following a 400-mg loading dose on day 1) with those of amoxicillin given as a 1-g oral dose three times daily for treatment of community-acquired pneumonia suspected to be due to Streptococcus pneumoniae. Success of treatment was determined by a combination of clinical assessment and chest radiography. Pneumococcal pneumonia was the confirmed diagnosis for 177 patients (54%). Overall rates of success among evaluable patients were equivalent between drugs, both at the end of treatment (sparfloxacin, 92%; amoxicillin, 87%) and at follow-up (sparfloxacin, 89%; amoxicillin, 84%). Sparfloxacin was well-tolerated and produced fewer gastrointestinal effects than amoxicillin. In conclusion, sparfloxacin is a safe and effective alternative to high-dose amoxicillin for the treatment of suspected pneumococcal community-acquired pneumonia.     

Information on the 5th meeting of the European Tick Study Group]

There is a strong association between prenatally diagnosed structural heart disease and fetal chromosomal abnormalities. Isomerism of the atrial appendages is an exception to this because the fetal karyotype is usually normal in this condition. A case of atrial isomerism diagnosed antenatally with a normal female karyotype but with a microdeletion of chromosome 22q11 is reported.     

Curiosity and mortality in aging adults: A 5-year follow-up of the Western Collaborative Group Study.

Research suggests that curiosity in older people is associated with maintaining the health of the aging central nervous system. We examined prospectively the relationship of curiosity in 1,118 community dwelling older men to subsequent survival over a 5-year period. Curiosity was measured when the participants were a mean age of 70.6 years. Initial levels of trait and state curiosity were higher in survivors than in those who subsequently died. After adjustment for other risk factors, the state curiosity-mortality association remained significant in the Cox regression model. Ancillary analyses in 1,035 older women (M age at initial examination?=?68.6 years) confirmed the pattern found in the men. State curiosity in these women was significantly associated with survival after adjustment for other risk factors. This is the first study to identify a predictive role for curiosity in the longevity of older adults. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

A study of introspectiveness in adolescents and young adults

The purpose of this study was to examine the relationship between introspectiveness and the theoretically related variables of close friend solidarity, self-esteem, and symptom patterns in early, middle, and late adolescents, as well as in young adults. Samples of early (n = 103), middle (n = 107), and late adolescents (n = 101) as well as young adults (n = 70) completed the Introspectiveness Scale, the Close Friend Solidarity Instrument, the Rosenberg Self-Esteem Scale, and the Symptom Pattern Scale in classroom settings. Hypotheses were tested using Pearson correlations, with a one-tailed test of significance. Introspectiveness was statistically, significantly, and positively related to close friend solidarity in all adolescents but not in young adults; introspectiveness was statistically, significantly, and inversely related to self-esteem in all adolescents but not in young adults. Finally, introspectiveness was statistically, significantly, and positively related to symptom patterns in all adolescents and in young adults.     

Prevalence of hepatitis A antibodies in southeastern Spain: a population-based study

OBJECTIVES: To identify variables, other than legal definitions, that may have influenced North Cheshire's Coroner in returning a verdict of 'suicide' or an 'open verdict' on unexpected deaths of the elderly. DESIGN: Retrospective review of all coroner's verdicts in North Cheshire during a 5-year period 1989-1993. MATERIAL: Forty-seven 'suicide' and 'open verdict' deaths in North Cheshire between 1989 and 1993 as defined in ICD classification 'E' codes E950-E959 and E980-E989, respectively, that were returned on the deceased aged 65 and above who died within North Cheshire. FINDINGS: Logistic regression analysis suggests that the Coroner's decision may be influenced by: intimation of intent, psychiatric history and method of death. Sex of the deceased, history of attempted suicide, social setting and history of alcohol problems did not appear significantly associated with coroner's verdict.
