Abstract
BACKGROUND Gonorrhea is the second most common bacterial sexually transmitted infection in the United States, with rising rates. Emerging antimicrobial resistance threatens public health, and vaccines are in development. This study documents patient-reported gonorrhea symptoms and health-related quality-of-life (HRQoL) impact in women who have sex with men (WSM), men who have sex with women (MSW), and men who have sex with men (MSM). METHODS Semistructured qualitative interviews were conducted (April 2021-March 2022) among US adults with recent (≤6 months) confirmed gonorrhea. Concept saturation was achieved, confirming adequate participant numbers to meet objectives. Elicited symptom and HRQoL impacts were used to develop a conceptual disease model. Common patient-reported outcome measure (PROM) items were compared with elicited concepts. RESULTS Thirty-two participants (15 WSM, 8 MSW, and 9 MSM) were included. Eight were asymptomatic, 6 had repeat infections, and 5 women and 4 men had complications (i.e., infertility or pelvic inflammatory disease, and urethritis, respectively).The most frequently reported symptoms were vaginal discharge (n = 11 of 12), dysuria (n = 10 of 12), and abdominal/vaginal pain (n = 9 of 12) for symptomatic WSM; dysuria (n = 5 of 6) and penile discharge (n = 4 of 6) for symptomatic MSW; and throat, testicular, or rectal pain (n = 4 of 6) for symptomatic MSM. All (symptomatic and asymptomatic) participants reported HRQoL impacts including negative emotional experiences (n = 31 of 32), and interference with sexual activity (n = 30 of 32), relationships (n = 24 of 32), and social life (n = 17 of 32). Concepts were poorly represented in existing PROMs. CONCLUSIONS Participants reported a diverse range of symptoms and HRQoL impacts, to help inform the value of new treatment and prevention options. More research is needed to quantify patient burden and develop PROMs.

Abstract
Background: The benefits of preventive interventions lack comprehensive evaluation in standard health technology assessments (HTA), particularly for rare and transmissible diseases. Objective: To identify possible considerations for future HTA using analogies between the treatment and prevention of rare diseases. Study design: An Expert panel meeting assessed whether one HTA assessment framework can be applied to assess both rare disease treatments and preventive interventions. Experts also evaluated the range of value elements currently included in HTAs and their applicability to rare, transmissible, and/or preventable diseases. Results: A broad range of value should be considered when assessing rare, transmissible disease prevention. Although standard HTA can be applied to transmissible diseases, the risk of local outbreaks and the need for large-scale prevention programs suggest a modified assessment framework, capable of incorporating prevention-specific value elements in HTAs. A 'Rule of Prevention' framework was proposed to allow broader value considerations anchored to severity, equity, and prevention benefits in decision-making for preventive interventions for rare transmissible diseases. Conclusion: The proposed prevention framework introduces an explicit initial approach to consistently assess rare transmissible diseases, and to incorporate the broader value of preventive interventions compared with treatment.

Abstract
INTRODUCTION Pertussis, a highly infectious respiratory disease caused by Bordetella pertussis, affects people of all ages. Older adults are particularly susceptible to its severe outcomes and complications. METHODS In this retrospective cohort study, the incidence rate of pertussis among individuals aged ≥ 50 years was assessed during 2009-2018 using Clinical Practice Research Datalink and Hospital Episode Statistics databases, United Kingdom. Health care resource utilisation (HCRU) and direct medical costs (DMCs) were compared between patients with a pertussis diagnosis and propensity score-matched controls (matched on demographic and clinical variables). RESULTS Among 5,222,860 individuals, 1638 had a pertussis diagnosis (incidence rate: 5.8 per 100,000 person-years; 95% confidence interval 5.5-6.0). Baseline (- 18 to - 6 months) HCRU and DMC were similar among 1480 pertussis patients and 1480 matched controls. However, there were increases in HCRU in the pertussis vs. matched cohort around the pertussis diagnosis (from months - 6 to - 1 to 5-11). The most notable increases (pertussis vs. controls) were in the rates of general practitioner (GP)/nurse visits (4.7-fold), clinical assessments (4.1-fold), and accident and emergency visits (3.0-fold) during the month before diagnosis and GP/nurse visits during the 2 months after diagnosis (2.5-fold) (all p < 0.001). DMCs were significantly higher in the pertussis cohort (p < 0.001). Total excess DMC in the pertussis cohort during months - 1 to + 11 was £318 per patient. CONCLUSION A pertussis diagnosis among adults aged ≥ 50 years resulted in significant increases in HCRU and DMC across several months around diagnosis. These results highlight the need for increased awareness of pertussis infection among adults aged ≥ 50 years and suggest that pertussis booster doses among this population should be considered.

Abstract
Background Invasive meningococcal disease (IMD) is uncommon, life-threatening, with many diverse sequelae. The aims were to: 1) comprehensively characterise the sequelae; 2) have a systematic application for sequelae impact in economic evaluation (EE). Methods Sequelae categorised as physical/neurological or psychological/behavioural were identified from a systematic review of IMD observational studies (OS) and EEs in high-income countries (published 2001–2020). A comprehensive map and EE-relevant list, respectively, included physical/neurological sequelae reported in ≥2OS and ≥ 2OS + 2EE (≥1OS and ≥ 1OS + 1EE for psychological/behavioural). Sequelae proportions were selected from the highest quality studies reporting most sequelae. Three medical experts independently evaluated the clinical impact of findings. Results Sixty-Six OS and 34 EE reported IMD sequelae. The comprehensive map included 44 sequelae (30 physical/neurological, 14 psychological/behavioural), of which 18 (14 physical/neurological and 4 psychological/behavioural) were EE-relevant. Experts validated the study and identified gaps due to limited evidence, underreporting of psychological/behavioural sequelae in survivors/their families, and occurrence of multiple sequelae in the acute phase and long-term. Conclusions The considerable burden of IMD sequelae on survivors and their families is potentially underestimated in EE, due to underreporting and poorly-defined subtle sequelae. When assessing IMD burden and potential interventions e.g., vaccination, sequelae range and duration, underreporting, and indirect burden on dependents should be considered. Supplementary Information The online version contains supplementary material available at 10.1186/s12889-022-13342-2. Invasive meningococcal disease survivors frequently suffer from variable sequelae. A broad sequelae map plus those relevant to economic evaluation (EE) were defined. Forty-four sequelae were selected: 30 physical/neurological and 14 psychological/behavioural. Eighteen EE-relevant sequelae included 14 physical/neurological and 4 psychological/behavioural Underreporting, family impact and multiple sequelae cases were critical gaps.

Abstract
Purpose The impact of pertussis in individuals with asthma is not fully understood. We estimated the incidence, health care resource utilization (HCRU), and direct medical costs (DMC) of pertussis in patients with asthma. Patients and Methods In this retrospective cohort study, the incidence rate of pertussis (identified using diagnostic codes) among individuals aged ≥50 years with an asthma diagnosis was assessed during 2009–2018 using Clinical Practice Research Datalink and Hospital Episode Statistics databases. HCRU and DMC were compared – between patients with diagnoses of asthma and pertussis (asthma+/pertussis+) and propensity score-matched patients with a diagnosis of asthma without pertussis (asthma+/pertussis–) – in the months around the pertussis diagnosis (–6 to +11). Results Among 687,105 individuals, 346 had a reported pertussis event (incidence rate: 9.6/100,000 person-years of follow-up; 95% confidence interval: 8.6–10.7). HCRU and DMC were assessed among 314 asthma+/pertussis+ patients and 1256 matched asthma+/pertussis– controls. Baseline HCRU was similar in both cohorts, but increases were observed in the asthma+/pertussis+ cohort from –6 to –1 month before to 2–5 months after diagnosis. Rates of accident and emergency visits, general practitioner (GP)/nurse visits, and GP prescriptions were 4.3-, 3.1-, and 1.3-fold, respectively, in the asthma+/pertussis+ vs asthma+/pertussis– cohorts during the month before diagnosis; GP/nurse visit rates were 2.0- and 1.2-fold during 0–2 and 2–5 months after diagnosis, respectively (all p<0.001). DMC was 1.9- and 1.6-fold during the month before and 2 months from diagnosis, respectively, in the asthma+/pertussis+ vs asthma+/pertussis– cohorts (both p<0.001). During months –1 to +11, DMC in the asthma+/pertussis+ cohort was £370 higher than in the asthma+/pertussis– controls. Conclusion A pertussis diagnosis among adults aged ≥50 years with asthma resulted in significant increases in HCRU and DMC across several months around diagnosis, suggesting lengthy diagnosis times and highlighting the need for prevention strategies.

Abstract
Chronic obstructive pulmonary disease (COPD) may increase the risk and severity of pertussis infection. Health care resource utilization (HCRU) and direct medical costs (DMC) of treating pertussis among patients with COPD are unknown. Reported incidence of pertussis among individuals aged ≥ 50 years with COPD was assessed in Clinical Practice Research Datalink and Hospital Episode Statistics databases during 2009-2018 using a retrospective cohort design. HCRU and DMC from the National Health Service perspective were compared between patients with COPD and pertussis and propensity score-matched patients with COPD without pertussis. Seventy-eight new pertussis events were identified among 387 086 patients with COPD aged ≥ 50 years (incidence rate: 4.73; 95% confidence interval 3.74-5.91 per 100 000 person-years). HCRU and DMC were assessed among 67 patients with COPD and pertussis and 267 matched controls. During the month before the pertussis diagnosis, the rates of general practitioner (GP)/nurse visits (4289 vs. 1774 per 100 patient-years) and accident and emergency visits (182 vs. 18 per 100 patient-years) were higher in the pertussis cohort; GP/nurse visits (2935 vs. 1705 per 100 patient-years) were also higher during the following 2 months (all p < 0.001). During the month before the pertussis diagnosis, annualized per-patient total DMC were £2012 higher in the pertussis cohort (£3729 vs. £1717; p < 0.001); during the following 2 months, they were £2407 higher (£5498 vs. £3091; p < 0.001). In conclusion, a pertussis episode among individuals with COPD resulted in significant increases in HCRU and DMC around the pertussis event.

Abstract
OBJECTIVES This cost-effectiveness analysis (CEA) of 4CMenB infant vaccination in England comprehensively considers the broad burden of serogroup B invasive meningococcal disease (MenB IMD), which has not been considered, or was only partially considered in previous CEAs. METHODS A review of previous MenB vaccination CEAs was conducted to identify aspects considered in the evaluation of costs and health outcomes of the disease burden of MenB IMD. To inform the model structure and comprehensive analysis, the aspects were grouped into 5 categories. A stepwise analysis was conducted to analyze the impact of each category, and the more comprehensive consideration of disease burden, on the incremental cost-effectiveness ratio (ICER). RESULTS MenB IMD incidence decreased by 46.0% in infants and children 0-4 years old within 5 years after introduction of the program. Stepwise inclusion of the 5 disease burden categories to a conventional narrow CEA setting reduced the ICER from £360 595 to £18 645-that is, considering the impact of all 5 categories, 4CMenB infant vaccination is cost-effective at a threshold of £20 000 per QALY gained. CONCLUSIONS When considering comprehensively the MenB IMD burden, 4CMenB infant vaccination can be cost-effective, a finding contrary to previous CEAs. This analysis allows policy decision-makers globally to infer the impact of current disease burden considerations on the cost-effectiveness and the comprehensive assessment necessary for MenB IMD. Although this comprehensive CEA can help inform decision making today, it may be limited in capturing the full disease burden and complex interactions of health and economics of MenB IMD.

Abstract
Background Pertussis affects people of all ages and can lead to severe complications in adults, including hospitalization. Pertussis immunity, whether vaccine-induced or from natural infection, wanes over time. Therefore, despite extensive pediatric vaccination against pertussis, adults remain susceptible to the disease. Here we present the reported incidence of pertussis in people ≥ 50 years old (≥ 50yo) in England and the United Kingdom (UK). Methods We performed an observational, retrospective database analysis using the UK Clinical Practice Research Datalink GOLD and Aurum primary care databases, and Hospital Episode Statistics database when available for English subjects (HES-Eng), 2009-2018. Occurrence of pertussis was identified by diagnostic codes recorded in primary care only for the UK subset, and primary care and/or secondary care for HES-Eng. Results In the ≥ 50yo UK population, a total of 47.1 million (m) person-years of follow-up (PYFU) including 28.5m PYFU for HES-Eng, were included. In the UK, the pertussis Incidence Rate (IR) across all years was 5.44 per 100,000 PYFU. Yearly IRs ranged from 0.79 – 11.40 per 100,000 PYFU and reflected the cyclic epidemiology of pertussis. A peak of IR was observed in 2012, known to be an outbreak year, and observed IRs were higher in 2013-2018 (4.75 – 9.73 per 100,000 PYFU) than 2009-2011 (0.79 – 1.48 per 100,000 PYFU). In the HES-Eng population, overall IR was 5.76 per 100,000 PYFU. IRs were highest in the younger age groups (HES-Eng: 8.88 in 50-54 yo; 1.42 in ≥ 85 yo) (see table 1 and 2). Table 1 ![]()
Table 2 ![]()
Conclusion The observed reported IR of pertussis was similar in the UK and HES-Eng populations, noting the inclusion of secondary care diagnoses in the latter. The dynamics of IRs across years are consistent with estimated IRs from Public Health England data. Considering the burden of pertussis established elsewhere in older adults, and their non-negligible contribution to the whole population incidence, strategies for the prevention of pertussis should include this age group.

Abstract
BACKGROUND The 13-valent pneumococcal conjugate vaccine (PCV13) is used for universal infant vaccination in Turkey. OBJECTIVES To assess the cost effectiveness of replacing PCV13 with pneumococcal nontypeable Haemophilus influenzae protein D conjugate vaccine (PHiD-CV). METHODS A Markov cohort model with monthly cycles following 1 cohort of infants over a 10-year time horizon was used. Local input parameters were obtained from published sources and expert consultation whenever possible. The model was adapted to estimate the health benefits and economic impact of each vaccine on invasive pneumococcal disease, pneumonia, and acute otitis media (AOM). An annual discount rate of 3% was used for benefits and costs (2016 euros). RESULTS Under base-case assumptions, vaccinating 1 birth cohort of 1 325 783 infants with PHiD-CV instead of PCV13 was predicted to have the same impact on meningitis and pneumonia, a similar impact on bacteremia (+30 cases), but greater reductions in AOM-related general practitioner visits (-34 955) and hospitalizations (-624). Assuming equal vaccine prices, PHiD-CV was predicted to be dominant over PCV13 (176 additional quality-adjusted life-years while saving €635 330 [discounted]). One-way sensitivity analysis indicated that varying the vaccine price differential had the largest effect on the incremental cost-effectiveness ratio, and then AOM parameters. Probabilistic sensitivity analysis predicted PHiD-CV to be dominant over PCV13 in 92.4% of simulations. CONCLUSIONS Any difference in price between PHiD-CV and PCV13 is expected to be the key driver of vaccine choice for preventing childhood pneumococcal disease in Turkey. At price parity, PHiD-CV use is likely to be a dominant strategy over the use of PCV13.

Abstract
Epidemiological data on acute otitis media (AOM), an infectious disease frequently affecting children, are lacking in some countries. This study was undertaken to assess the incidence of AOM in children ≤5 years in Saudi Arabia, Oman, Pakistan, and Turkey, as well as the economic burden from a parent/caregiver perspective. Medical records of 4043 children (Saudi Arabia = 1023, Oman = 998, Pakistan = 1022, Turkey = 1000) were retrospectively reviewed and the incidence of AOM episodes calculated from suspected and confirmed cases. Using a standardized Health Economics Questionnaire, parents recorded resource use and expenses incurred per AOM episode [in local currency and converted to US dollars (USD)]. The overall incidence of AOM episodes per 1000 person–years was: Saudi Arabia, 207 [95% confidence interval (CI): 178–238]; Oman, 105 (95% CI: 85–127); Pakistan, 138 (95% CI: 116–163); and Turkey, 99 (95% CI: 79–123). The mean total out-of-pocket healthcare expense incurred by parents/caregivers per episode was: Saudi Arabia USD67.1 [standard deviation (SD) = 93.0], Oman USD16.1 (SD = 16.4), Pakistan USD22.1 (SD = 20.5), and Turkey USD33.6 (SD = 44.9). The incidence of AOM episodes varied across all four countries, probably due to different diagnostic and management practices. Nevertheless, our results confirm that AOM causes a substantial burden to public health, reinforcing the need for cost-effective prevention strategies.

Abstract
Neurodevelopmental schizophrenia seems to be caused by impaired cerebral development and is supposed to be associated with obstetric complications (OCs), poor premorbid adjustment, schizotypal or schizoid personality traits and negative symptoms. In the present study, 36 schizophrenic and schizoaffective patients and their same-sex, healthy siblings were recruited. They were diagnosed according to DSM-III-R, using structured psychiatric interviews and a consensus of 2 psychiatrists. Information on OCs, birth weight, premorbid social and learning functioning was obtained from their mothers. The main results show significant differences in OCs, birth weight, premorbid social and learning functioning between patients and their same-sex, healthy siblings. Using multivariate analyses, both premorbid variables were again identified to discriminate well between affected and unaffected siblings. Our findings seem to confirm the concept of schizophrenia as a neurodevelopmental process.

Abstract
OBJECTIVE Schizophrenia is a relatively common, often chronic and debilitating mental illness. Evidence from various studies has clearly demonstrated that genetic factors contribute substantially to the etiology. The goal of this study was to identify chromosomal regions likely to contain schizophrenia susceptibility genes. METHODS A genome-wide map of 388 microsatellite DNA markers was genotyped in 5 schizophrenia families. Nonparametric linkage analysis (Genehunter) was used to assess the pattern of allele sharing at each marker locus relative to the presence of disease. RESULTS Nonparametric linkage scores did not reach a genome-wide level of statistical significance (p < 0.00002) or a p value suggestive of linkage (p < 0.007) for any marker; however, one p value suggested replicated linkage (p < 0.01) at chromosome 6p24 in region D6S309 (p = 0.0047). Furthermore, 11 markers resulted in p < 0.05 at chromosomes 6p, 6q, 10q, 12q and 14q. CONCLUSIONS Despite the differences in diagnostic schemes, in markers used and methods of analyses between studies published so far, we think that our result supports the notion that there is possibly some consistent evidence for replicated linkage of a schizophrenia susceptibility locus around the region of D6S309 at chromosome 6p24.

Abstract
The aim of the investigation was to test genes for predisposition to bipolar affective disorder. Therefore, we studied candidate genes in a sample of unrelated patients (n = 102) and healthy controls (n = 79) of Austrian origin, searching for a possible association between polymorphic DNA markers of 5 candidate genes (serotonin transporter, 5-HTT; serotonin 2a receptor, 5-HT2a; dopamine D2 receptor, DRD2; dopamine D3 receptor, DRD3; dopamine transporter, DAT1) and bipolar disorder. There was an association between allelic and genotypic frequencies of 5-HTT and affection status (p = 0.014 and p = 0.017, respectively). However, after correction for multiple comparisons (Bonferroni), these results did not remain significant. Nevertheless, the findings might suggest that alterations in the structure of 5-HTT are involved in the pathogenesis of bipolar disorder, which could have major implications in treatment. No association between 5-HT2a, DRD2, DRD3, DAT1 and bipolar disorder was found.

Abstract
This study was initiated to develop an animal model of type 2 diabetes in a non-obese, outbred rat strain that replicates the natural history and metabolic characteristics of the human syndrome and is suitable for pharmaceutical research. Male Sprague-Dawley rats (n = 31), 7 weeks old, were fed normal chow (12% of calories as fat), or high-fat diet (40% of calories as fat) for 2 weeks and then injected with streptozotocin (STZ, 50 mg/kg intravenously). Before STZ injection, fat-fed rats had similar glucose concentrations to chow-fed rats, but significantly higher insulin, free fatty acid (FFA), and triglyceride (TG) concentrations (P < .01 to .0001). Plasma insulin concentrations in response to oral glucose (2 g/kg) were increased 2-fold by fat feeding (P < .01), and adipocyte glucose clearance under maximal insulin stimulation was significantly reduced (P < .001), suggesting that fat feeding induced insulin resistance. STZ injection increased glucose (P < .05), insulin (P < .05), FFA (P < .05), and TG (P < .0001) concentrations in fat-fed rats (Fat-fed/STZ rats) compared with chow-fed, STZ-injected rats (Chow-fed/STZ rats). Fat-fed/STZ rats were not insulin deficient compared with normal chow-fed rats, but had hyperglycemia and a somewhat higher insulin response to an oral glucose challenge (both P < .05). In addition, insulin-stimulated adipocyte glucose clearance was reduced in Fat-fed/STZ rats compared with both chow-fed and Chow-fed/STZ rats (P < .001). Finally, Fat-fed/STZ rats were sensitive to the glucose lowering effects of metformin and troglitazone. In conclusion, Fat-fed/STZ rats provide a novel animal model for type 2 diabetes, simulates the human syndrome, and is suitable for the testing of antidiabetic compounds.

Abstract
Alterations in dopamine neurotransmission have been hypothesized to play a role in the etiology of schizophrenia. We considered the dopamine D3 receptor gene on chromosome 3 as a candidate gene for an association analysis. We compared PCR-based genotype markers for healthy controls (n=120) and patients (n=95) with schizophrenia and schizophrenia spectrum disorders as diagnosed by consensus according to DSM-III-R. Our results possibly indicate an association of schizoaffective disorder with DRD3 homozygosity (P=0.056).

Abstract
Delinquency among depressed patients plays a minor role in criminal behavior. Among the most tragic associations between depression and criminality are cases of extended suicide or suicide attempt. We studied psychopathology, personality, and psychosocial stressors of 9 Austrian females who committed a serious extended suicide attempt. They were admitted for treatment at a special department of the Justizanstalt Wien-Josefstadt, Aussenstelle Wilhelmshöhe. Patients were diagnosed according to ICD-10 as severely depressed with (n = 6) or without (n = 3) psychotic features. After stabilization we diagnosed the following personality disorders: anxious-avoidant (n = 5), paranoid (n = 1), combined (n = 1) and borderline type (n = 1). Traits of the typus melancholicus were found in 5 patients. Seven females were pretreated before the offence by a psychiatrist or a psychologist; 4 of them had committed at least one suicide attempt in the past. Main psychosocial stressors mentioned by patients in the context of the offence were overstrain, marital and/or financial problems. One female killed her child under the influence of acoustic hallucinations. Patients with traits of the melancholic type showed an altruistic and hypernomic motive for killing as well as a psychotic identification with the victim, whereas in the other cases egocentric motives were in the forefront. Potential risk factors for an extended suicide attempt will be discussed.

Abstract
In an 8-week double-blind placebo-controlled trial we studied the efficacy of fluoxetine (FLX) in 53 Austrian patients with obsessive compulsive disorder (OCD) diagnosed according to DSM-III-R. The dosage of FLX was fixed at either 20, 40, or 60 mg per day. Response was prospectively defined as an at least 25% reduction on the Yale-Brown Obsessive Compulsive Scale (Y-BOCS) and an improvement on Clinical Global Impression (CGI) rating to at least "much improved" at the endpoint. Patients treated with at least 40 mg FLX per day showed significantly higher response rates than did those receiving either placebo or FLX 20 mg/day. Compulsions were more reduced than obsessions and we also observed a strong placebo effect which is largely attributable to an improvement in the Y-BOCS compulsion subscore.

Abstract
Personality traits have been found as strong predictors for treatment response in different psychiatric disorders. We administered the Tridimensional Personality Questionnaire, which measures the three personality dimensions: novelty seeking, harm avoidance (HA), and reward dependence, as introduced by Cloninger in a multicenter study (11 centers in the United Kingdom, Eire, Switzerland, and Austria) with detoxified alcohol-dependent patients (n = 521). The objective of this study was to evaluate a possible predictive value of these three dimensions on relapse over 1 -year follow up. A logistic regression analysis showed that novelty seeking is a strong predictor for relapse in detoxified male alcoholics (p = 0.0007; p values adjusted for treatment), but not in females. In both sexes, HA and reward dependence were of no predictive value. However, we found a trend for significance of HA for predicting "early" relapse (4 weeks) in females (p = 0.074). Our results show that Tridimensional Personality Questionnaire personality traits have direct clinical applications for prediction of relapse in detoxified alcohol dependents and indicate the necessity of additional therapeutic treatment in risk groups.

Abstract
In various genetic disorders it has been observed that the severity of illness increases and the age at onset decreases in successive generations. This phenomenon is termed anticipation. We sampled 15 families, totalling 123 individuals with at least one person affected by a disease of the schizophrenia spectrum in the index generation in each family (IG; n = 33 affected out of a total of 67 individuals) and in the parental generation (PG; n = 16 affected out of a total of 56 individuals). The pedigrees had originally been identified for linkage studies in schizophrenia. We found a significant difference between IG and PG regarding severity of illness as defined by Kendler et al's hierarchical model of categories of the schizophrenia spectrum (p = 0.001). Age at onset was significantly earlier in the IG (21.6 +/- 6.6 years) than in the PG (40.2 +/- 9.2 years) (p = 0.0001). We excluded a potential birth cohort effect by investigating a control sample consisting of two non-overlapping birth cohorts of patients with schizophrenia. Age at onset between the two groups of the control sample did not differ. Anticipation is an important aspect in the investigation of a possible genetic basis, at least for the familial form of schizophrenia. Active research on a molecular level with special emphasis on trinucleotide repeats might be able to shed further light on this phenomenon.

Abstract
Extracts of the creosote bush (Larrea tridentata, family Zygophyllaceae) have long been used as a folk remedy for Type II (non-insulin-dependent) diabetes by native Americans in southwestern North America. In this study we have evaluated the metabolic effects of masoprocol, a pure compound isolated from the creosote bush, in a rat model of Type II diabetes. Animals were fed a 20% fat (by weight) diet for 2 weeks prior to intravenous injection with streptozotocin (STZ, 0.19 mmol/kg). Diabetic animals (glucose 16-33 mmol/l) were treated with vehicle, metformin (0.83 mmol/kg body weight) or masoprocol (0.83 mmol/kg body weight) twice a day for 4 days. Masoprocol treatment lowered glucose concentrations an average of 35% compared with vehicle (14.2+/-1.1 vs 21.7+/-1.0 mmol/l, p < 0.001), a reduction similar to metformin treatment (12.8+/-0.9 mmol/l), without any change in insulin concentration. Masoprocol treatment also lowered triglyceride concentrations 80% compared with vehicle (1.0+/-0.1 vs 4.8+/-0.3 mmol/l, p < 0.001), a reduction far greater than following metformin treatment (3.6+/-0.3 mmol/l). Non-esterified fatty acid and glycerol concentration were decreased by approximately 65% by masoprocol compared with vehicle, a reduction approximately twice as great as seen with metformin (p < 0.001). The effect of masoprocol on in vivo insulin-mediated glucose disposal was evaluated by infusing fat-fed/STZ rats with glucose (0.22 mmol kg x min(-1)) and insulin (30 pmol x kg x min(-1)) for 5 h. In response to the infusion, steady-state plasma glucose concentrations were reduced 30% in masoprocol-treated animals compared with vehicle controls (p < 0.05) with no change noted in rats treated with metformin. The effect of masoprocol treatment was also tested in primary adipocytes isolated from normal animals. Adipocytes treated with masoprocol (30 micromol/l) had higher basal and insulin-stimulated glucose clearance than did adipocytes treated with vehicle (p <0.05). These data show that masoprocol decreases both plasma glucose and triglyceride concentrations in fat-fed/STZ rats, presumably as a result of its ability to both increase glucose disposal and decrease lipolysis.

Abstract
In the present study, the occurrence of tardive dyskinesia (TD) in chronic schizophrenia patients was investigated in relation to pharmacogenetic polymorphisms. It is known that the metabolism of important neuroleptic drugs is influenced by polymorphisms of the CYP2D6 gene, which encodes the cytochrome P450 enzyme debrisoquine/spartein hydroxylase. Forty-five patients meeting the DSM IV criteria for schizophrenia, chronic course, were recruited. The patients were examined for the mutations CYP2D6*3, CYP2D6*4 and CYP2D6*5. The CYP2D6 genotype distribution in the patient group did not differ from that in healthy Caucasian populations. Tardive dyskinesia was found in 26 patients (57.8%). When comparing patients without CYP2D6 mutations with patients heterozygous for one mutation, we found a higher incidence of TD in the latter (81.3% vs. 46.4%, p = 0.031, multiple regression analysis), which demonstrates a significant influence of the CYP2D6 genotype of the manifestation of TD. As slight differences in the metabolism of drugs in patients heterozygous for CYP2D6 mutations and patients without such mutations are known, we conclude that heterozygous carriers of 2D6 mutated alleles may show an increased susceptibility to developing TD.

Abstract
An ethnomedically-driven approach was used to evaluate the ability of a pure compound isolated from the creosote bush (Larrea tridentata) to lower plasma glucose concentration in two mouse models of type 2 diabetes. The results indicated that plasma glucose concentration fell approximately 8 mmol/l in male C57BL/ks-db/db or C57BL/6J-ob/ob mice following the oral administration of masoprocol (nordihydroguaiaretic acid), a well known lipoxygenase inhibitor. The decline in plasma glucose concentration following masoprocol treatment in the mice was achieved without any change in plasma insulin concentration. In addition, oral glucose tolerance improved and the ability of insulin to lower plasma glucose concentrations was accentuated in masoprocol-treated db/db mice. These data raise the possibility that masoprocol, or other lipoxygenase inhibitors, represents a new approach to the pharmacological treatment of Type 2 diabetes.

Abstract
We performed a meta-analysis of over 30 case-control studies of association between schizophrenia and a bi-allelic, Bali polymorphism in exon 1 of the dopamine D3 receptor gene. We observed a significant excess of both forms of homozygote in patients (P = 0.0009, odds ratio (OR) = 1.21, 95% Confidence Interval (CI) = 1.07-1.35) in the combined sample of 5351 individuals. No significant heterogeneity was detected between samples and the effects did not appear to be the product of publishing bias. In addition we undertook an independent, family-based association study of this polymorphism in 57 parent/proband trios, taken from unrelated European multiplex families segregating schizophrenia. A transmission disequilibrium test (TDT) showed a significant excess of homozygotes in schizophrenic patients (P = 0.004, odds ratio (OR) = 2.7, 95% CI = 1.35-5.86). Although no significant allelic association was observed, a significant association was detected with the 1-1 genotype alone (P = 0.02, OR = 2.32, 95% CI = 1.13-4.99). In addition when the results of the family-based association study were included in the meta-analysis, the homozygosity effect increased in significance (P = 0.0002, OR = 1.23, 95% CI = 1.09-1.38). The results of the meta-analysis and family-based association study provide independent support for a relationship between schizophrenia and homozygosity at the Bali polymorphism of the D3 receptor gene, or between a locus in linkage disequilibrium with it.

Abstract
As part of the European Multicentre Association Study of Schizophrenia (EMASS), we studied polymorphisms in the dopamine DRD2 and DRD3 receptor genes. The EMASS collaboration was established to create a large, statistically powerful sample of schizophrenic patients and controls from different European centres. Previous studies have suggested associations between schizophrenia and the Ser311Cys polymorphism in exon 7 of the dopamine DRD2 receptor gene [Arinami et al., (1994): Lancet 343:703-704] and a polymorphism Ser9gly in exon 1 of the dopamine DRD3 receptor gene [Crocq et al. (1992): J Med Genet 29:858-860]. We tested for these associations in samples of 373 and 413, and 311 and 306 patients and controls, respectively. We found no evidence for allelic association between schizophrenia and the Cys311 variant of the DRD2 receptor gene and no homozygotes for this variant were observed by any group. However, an excess of homozygotes for both alleles of the DRD3 polymorphism was observed in schizophrenic patients (chi2 = 8.54, P = 0.003, odds ratio = 1.64, 95% CI = 1.18-2.29). We also observed a significant excess of the 1-1 (Ser9Ser) genotype (chi2 = 8.13, P = 0.004, odds ratio = 1.7, 95% CI = 1.18-2.4). No evidence of heterogeneity between samples was detected and there was no evidence of an allelic association. These findings suggest that the rare Cys311 variant in exon 7 of the DRD2 receptor gene does not play a role in the pathogenesis of schizophrenia in European populations. Currently, our results do support the previous findings of an association between increased homozygosity of the Ser/Gly variant of the Dopamine D3 receptor gene and schizophrenia.

Abstract
This report describes the application of a unified biosocial model of personality developed by C.R. Cloninger to a sample of families identified through a proband with schizophrenia and a sample of controls. Families of schizophrenic patients were ascertained in USA and Austria. We could detect differences between females and males in their response to positive reinforcement (Reward Dependence) and differences between young and old people with respect to the response to new and/or exciting situations (Novelty Seeking). In general, results obtained for individuals from schizophrenia families and controls were similar. These results are not substantially influenced by psychiatric disorders in individuals. Psychiatric diagnosis may have an influence on the third dimension of Cloninger's model, designated Harm Avoidance. Analysis showed that patients with a diagnosis of schizophrenia or from the schizophrenia spectrum try harder to avoid punishment or aversive stimuli than family members with another psychiatric disorder or without a psychiatric diagnosis as well as controls. The results are promising and further research is needed to evaluate the structure of the proposed personality model in families and the relationship of personality to psychiatric status.

Abstract
Pulver et al. [1994a] reported modest linkage evidence for a dominantly (D) inherited "schizophrenia gene" in the vicinity of IL2RB on chromosome 22q12, and Coon et al. [1994] adduced moderate evidence under a recessive (R) model. We report here a replication study to test the hypothesis that one of these two models (or a third, intermediate (I) model) adequately describes the co-segregation of schizophrenia and chromosome 22q12 markers in an independent sample of 23 multiplex families. Altogether nine transmission models were evaluated. The models differed depending on whether the 15 family members with a diagnosis of schizophrenia spectrum disorders were considered unaffected (a "narrow" (N) definition), affected (a "wide" (W) definition), or declared "unknown" (U). The entire region between D22S268 and D22S307 is excluded (i.e., lod <-2) for models RN, RW, RU, and IW. Lod scores for the remaining models are uniformly negative; albeit, equivocal with respect to the dominant hypothesis over a small region between D22S268 and IL2RB. Nonparametric analysis under both diagnostic criteria also failed to yield any evidence for a susceptibility locus in this region of chromosome 22.

Abstract
Anticholinergic drugs such as biperiden are used for the treatment of extrapyramidal side effects (EPS) induced by neuroleptics such as haloperidol. The effects of biperiden and haloperidol plasma levels on EPS were studied in 29 chronically ill schizophrenics. The results show relationships between biperiden dose and biperiden plasma levels (BPL), and between BPL and haloperidol plasma levels (HPL). Neither BPL nor HPL seem to influence EPS.

Abstract
There are some reports about neuropsychiatric side effects associated with the intake of the antimalarial drug mefloquine. We report a long-term observation of a patient suffering for his first time on an acute psychosis under mefloquine prophylaxis. Mefloquine's role as a drug possibly inducing psychosis and the influence of vulnerability therefore will be discussed.
