A fair appraisal of the public health significance of cannabis use has been hampered by the polarised opinions about its health effects expressed by partisans on both sides of the debate on its legal status. The findings of a recent review of the literature on the adverse health and psychological effects of cannabis are used to estimate the major probable public health risks of cannabis use in Australia. These appear to be, in order of approximate public health importance: adverse psychological effects; motor vehicle accidents; cannabis dependence; respiratory disease; precipitation and exacerbation of schizophrenia in vulnerable individuals; low-birthweight babies; and perhaps subtle cognitive impairment. On current patterns of use, cannabis use is a modest public health concern by comparison with alcohol and tobacco, although given the scale of public health damage caused by the latter drugs, and the currently low prevalence of regular cannabis use, this is not cause for complacency.

We studied the comorbidity of psychiatric and physical disorders in a sample (n = 11,017) from the unselected, general population, Northern Finland 1966 Birth Cohort. During the period 1982-1994, hospital-treated psychiatric patients were more likely than people without psychiatric diagnoses to have been treated for physical disease in hospital wards, 298 out of 387 (77%) vs 6687 out of 10,630 (62.9%) (OR = 2.0, 95% CI = 1.6-2.5). Injuries, poisonings and indefinite symptoms were a more common reason for hospital treatment in people with schizophrenia or other psychiatric disorder as compared with people without a psychiatric disorder. Men with psychiatric disorder had more than a 50-fold risk for poisoning by psychotropic drugs (OR = 52.6, 95% CI = 27.7-99.8), women with psychiatric disorder a 20-fold risk (OR = 19.0, 95% CI = 9.5-38.1) and schizophrenics more than a 30-fold (OR = 37.5, 95% CI = 19.1-73.8). Men with psychiatric disorders were more commonly hospitalised for a variety of gastrointestinal disorders and circulatory diseases (OR = 2.3, 95% CI = 1.2-4.4), as compared with men with no psychiatric disorder. Respiratory diseases (OR = 2.2, 95% CI = 1.2-4.2, vertebral column disorders (OR = 4.2, 95% CI = 1.8-9.9), gynaecological disorders (OR = 2.1, 95% CI = 1.2-3.6) and induced abortions (OR = 1.8, 95% CI = 1.2-2.7) were more prevalent in women with psychiatric disorder than in other women. Epilepsy was strongly associated with schizophrenia (OR = 11.1, 95% CI = 4.0-31.6). Nervous and sensory organ diseases in general (OR = 2.5, 95% CI = 1.1-5.8) and inflammatory diseases of the bowel (OR = 12.8, 95% CI = 3.8-42.7) were also overrepresented in schizophrenia when compared with people without a psychiatric disorder. Our results indicate that physicians must be alert for psychiatric disorder, and mental health professionals must be aware of the considerable morbidity in their patients.

Using the National Health Interview Survey Disability Supplement of 1994 to 1995, we examined the factors associated with employment among Americans with disabilities. Persons with disabilities who were more educated were more likely to be working. Married men were more likely to work than unmarried men (odds ratio [OR], 1.58). Blacks were less likely to work than whites (OR, 0.56). Persons with disabilities related to cardiovascular disease (OR, 0.23), musculoskeletal disease (OR, 0.37), and respiratory disease (OR, 0.23) were less likely to work than other Americans with disabilities. Among persons with psychiatric disorders, there was considerable variety in the propensity to work. Persons with schizophrenia (OR, 0.24) and paranoid delusional disorder (OR, 0.34) were markedly less likely to work; persons with bipolar disorder (OR, 0.60) and major depression (OR, 0.69) were also less likely to work. Lastly, persons with self-reported alcohol abuse (OR, 1.30) were more likely to work, and persons with self-reported drug abuse (OR, 0.93) were not less likely to work, than others in our study population of Americans with disabilities.

Individuals with schizophrenia have standardised mortality rates which are double that of the general population. In addition to suicide, high rates of cardiovascular and respiratory disease contribute to this raised mortality rate. Although clozapine has been reported to improve psychotic symptoms and decrease suicide rates, attention has recently focussed on its potential to increase cardiovascular risk factors including obesity, dyslipidemia and diabetes mellitus. This study aimed to ascertain the prevalence of these risk factors in a cohort of Irish outpatients treated with clozapine.

The aim of the present paper was to clarify the factors influencing subjective daytime sleepiness in patients with obstructive sleep apnea syndrome (OSAS). Subjects included 230 adult male OSAS patients aged 20-73 years. Single and multiple linear regression analyses were performed to estimate the association between the Epworth Sleepiness Scale (ESS) and the following variables: Minnesota Multiphasic Personality Inventory (MMPI), Self-Rating Depression Scale (SDS), age, body mass index (BMI), sleep duration during the preceding month and apnea-hypopnea index (AHI). Single linear regression analysis showed that age had a negative association with ESS score, while BMI, AHI, SDS, hypochondriasis (Hs), hysteria, psychopathic deviant, psychasthenia, schizophrenia and hypomania on the MMPI had a positive association with ESS score. However, the other remaining parameters such as nocturnal sleep duration during the preceding month, depression, masculinity-femininity, paranoia, social introversion on the MMPI had no statistical association with ESS score. Multiple linear regression analysis with stepwise elimination method was applied to choose the significant factors associated with ESS. It was found that three variables including age, AHI and Hs scores were independent factors influencing ESS score. The R(2) for the model was 0.14, suggesting that these factors account for 14% of possible variance of subjective daytime sleepiness of OSAS patients. These results suggest that subjective daytime sleepiness in patients with OSAS may be influenced not only by the severity of respiratory disorder indices but also by certain personality characteristics affecting Hs score and by age.

A meta-analysis of 13 independent microarray data sets was performed and gene expression profiles from cystic fibrosis (CF), similar disorders (COPD: chronic obstructive pulmonary disease, IPF: idiopathic pulmonary fibrosis, asthma), environmental conditions (smoking, epithelial injury), related cellular processes (epithelial differentiation/regeneration), and non-respiratory "control" conditions (schizophrenia, dieting), were compared. Similarity among differentially expressed (DE) gene lists was assessed using a permutation test, and a clustergram was constructed, identifying common gene markers. Global gene expression values were standardized using a novel approach, revealing that similarities between independent data sets run deeper than shared DE genes. Correlation of gene expression values identified putative gene regulators of the CF transmembrane conductance regulator (CFTR) gene, of potential therapeutic significance. Our study provides a novel perspective on CF epithelial gene expression in the context of other lung disorders and conditions, and highlights the contribution of differentiation/EMT and injury to gene signatures of respiratory disease.

Although COVID-19 is predominantly a respiratory disease, it is known to affect multiple organ systems. In this article, we highlight the impact of SARS-CoV-2 (the coronavirus causing COVID-19) on the central nervous system as there is an urgent need to understand the longitudinal impacts of COVID-19 on brain function, behaviour and cognition. Furthermore, we address the possibility of intergenerational impacts of COVID-19 on the brain, potentially via both maternal and paternal routes. Evidence from preclinical models of earlier coronaviruses has shown direct viral infiltration across the blood-brain barrier and indirect secondary effects due to other organ pathology and inflammation. In the most severely ill patients with pneumonia requiring intensive care, there appears to be additional severe inflammatory response and associated thrombophilia with widespread organ damage, including the brain. Maternal viral (and other) infections during pregnancy can affect the offspring, with greater incidence of neurodevelopmental disorders, such as autism, schizophrenia and epilepsy. Available reports suggest possible vertical transmission of SARS-CoV-2, although longitudinal cohort studies of such offspring are needed. The impact of paternal infection on the offspring and intergenerational effects should also be considered. Research targeted at mechanistic insights into all aspects of pathogenesis, including neurological, neuropsychiatric and haematological systems alongside pulmonary pathology, will be critical in informing future therapeutic approaches. With these future challenges in mind, we highlight the importance of national and international collaborative efforts to gather the required clinical and preclinical data to effectively address the possible long-term sequelae of this global pandemic, particularly with respect to the brain and mental health.

Psychotic disorders are associated with premature mortality, but research was primarily based on Western countries and rarely examined non-affective psychoses other than schizophrenia (ONAP). This population-based cohort study investigated excess mortality in 46 896 schizophrenia and 20 651 ONAP patients between January 2006 and December 2016 in Hong Kong (HK), by estimating all-cause and cause-specific standardized mortality ratios (SMRs), and life-years lost (LYLs), a recently developed, more precise reduced life expectancy measure taking into account the illness onset (age at first-recorded diagnosis). Changes in mortality metrics over the study period were assessed. Study data were retrieved from a territory-wide medical-record database of public healthcare services to 7.5 million HK residents. Results showed that schizophrenia and ONAP patients had higher all-cause (schizophrenia: SMR: 2.49 [95% CI: 2.43-2.55]; ONAP: 2.00 [1.92-2.09]), natural-cause (1.80 [1.74-1.85]; 1.47 [1.40-1.54]), and unnatural-cause (6.97 [6.47-7.49]; 8.53 [7.61-9.52]) mortality rates than general population. Respiratory diseases, cardiovascular diseases, and cancers accounted for the majority of deaths in patient cohorts. Men and women with schizophrenia had 9.53 years and 8.07 years of excess LYLs, respectively. For ONAP, excess LYLs was 8.18 years for men and 5.44 years for women. The overall mortality gap remained similar for both patient groups over time despite their improved longevity and declined unnatural-cause mortality rates. Taken together, schizophrenia and ONAP are associated with increased premature mortality and substantially reduced lifespan in a predominantly Chinese population, with excess deaths mainly attributed to a natural cause. Persistent mortality gap highlights an urgent need for targeted interventions to improve the physical health of patients with psychotic disorders.
