Onset of mania was evaluated retrospectively in 48 bipolar manic-depressive patients. Mania occurred as the initial episode in 40% of cases. In patients with initial episode of depression, approximately 80% developed mania prior to their third episode of depression and within 5 years from the onset of this illness. Differences in type of illness onset were related to family history of bipolar illness and sex of the proband. Male patients with a positive family history were significantly more likely to manifest mania at onset of illness.

Objectives: Although clear advances have been achieved in the study of early-onset schizophrenia (EOS), little is known to date about premorbid and prodromal neuropsychological functioning in EOS. Method: Here, we report on a case of an adolescent male with EOS who underwent neuropsychological testing before and after illness onset. Results: Marked cognitive deficits in the domains of attention, set-shifting, and verbal memory were present both pre-onset and during the course of schizophrenia, though only deficits in verbal memory persisted after illness-onset and antipsychotic treatment. Conclusion: The findings of this case study suggest that impairments in the verbal memory domain are particularly prominent symptoms of cognitive impairment in prodromal EOS and persist in the course of the disorder, which further demonstrates the difficult clinical situation of adequate schooling opportunities for adolescent patients with EOS.

Copper Overload

: Wilson disease is a congenital disorder of copper metabolism whose pathogenesis remains, al least in part, unknown. Subjects carrying the same genotype may show completely different phenotypes, differing for the age at illness onset or for the hepatic, neurologic or psychiatric clinical presentation. The inhability to find a unequivocal correlation between the type of mutation in the ATPase copper transporting beta (ATP7B) gene and the phenotypic manifestation, induced many authors to look for epigenetic factors interacting with the genetic changes. Here the evidences regarding the ability of copper overload to change the global DNA methylation status are discussed.

Estimation of the effective reproduction number, R(t), of coronavirus disease (COVID-19) in real-time is a continuing challenge. R(t) reflects the epidemic dynamics based on readily available illness onset data, and is useful for the planning and implementation of public health and social measures. In the present study, we proposed a method for computing the R(t) of COVID-19, and applied this method to the epidemic in Osaka prefecture from February to September 2020. We estimated R(t) as a function of the time of infection using the date of illness onset. The epidemic in Osaka came under control around 2 April during the first wave, and 26 July during the second wave. R(t) did not decline drastically following any single intervention. However, when multiple interventions were combined, the relative reductions in R(t) during the first and second waves were 70% and 51%, respectively. Although the second wave was brought under control without declaring a state of emergency, our model comparison indicated that relying on a single intervention would not be sufficient to reduce R(t) < 1. The outcome of the COVID-19 pandemic continues to rely on political leadership to swiftly design and implement combined interventions capable of broadly and appropriately reducing contacts.

SUMMARYAims– To highlight the major discrepancies that emerged between evidence and routine practice in the framework of the SIEP-DIRECT's Project (DIscrepancy betweenRoutine practice andEvidence in psychiatricCommunityTreatments onSchizophrenia). The Project was conducted in 19 Italian mental health services (MHS), with the aims of: a) evaluating the appropriateness of the NICE Guidelines for Schizophrenia in the Italian context, b) developing and testing a set of 103 indicators that operationalised preferred clinical practice requirements according to the NICE Guidelines, and c) evaluating their actual application in Italian MHSs.Methods– The indicators investigated five different areas: common elements in all phases of schizophrenia; first episode treatment; crisis treatment; promoting recovery; the aggressive behaviour management.Results– The NICE recommendations examined were judged in most instances to be appropriate to the Italian MHS context, and the indicators fairly easy to use. The more severe and frequently encountered evidence-practice discrepancies were: lack of written material, guidelines, and information to be systematically provided to users; lack of intervention monitoring and evaluation; difficulty in implementingspecific and structured forms of intervention; difficulty in considering patients' family members as figures requiring targeted support themselves and who should also be regularly involved in the patient care process.Conclusions– The key actions to be undertaken to favour implementation of evidence-based routine practices are: focussing on mental illness onset and family support/involvement in care; planning training activities aimed at achieving specific treatment goals; encouraging MHS participation in evaluation activities; identifying thresholds for guideline application and promoting specific guideline implementation actions; and activating decision making and resource allocationprocesses that rely more strictly on evidence and epidemiological assessment. These considerations are of value for rethinking the model of community psychiatry in Italy as well as in other countries.Declaration of Interest: None.

Multiple Threshold

Twin data on bipolar and unipolar affective disorders are analyzed by multiple threshold models of inheritance. The two illness types are represented in the models on a continuum of genetic–environmental liability in which bipolar illness has a higher liability threshold than unipolar disorder. Autosomal single major locus model provides an acceptable fit to observed concordance rates in monozygotic twins. The multifactorial-polygenic model is rejected.
