Psychiatric Morbidity and Referral on Two General Medical Wards

Psychiatric morbidity among 230 medical inpatients was determined by a two-stage screening procedure, using the General Health Questionnaire and Standardized Psychiatric Interview. Of these patients, 23% were considered psychiatrically ill, affective disorders being the commonest illnesses encountered; and 27 (12%) were psychiatrically referred. While referral was related to severity of psychiatric illness and previous psychiatric illness, the degree to which the psychiatric illness obtruded or created problems in management appeared more crucial in determining referral. In half of those with psychiatric illness the problems did not appear to have been detected or dealt with. It is suggested that medical clerking should routinely include questions about mood and psychological responses to illness.     

Caring for mentally ill people.

Despite legislation to harmonise mental health practice throughout Europe and convergence in systems of training there remains an extraordinary diversity in psychiatric practice in Europe. Approaches to tackling substance misuse vary among nations; statistics on psychiatric morbidity are affected by different approaches to diagnosis and treatment of psychiatric disorders; attitudes towards mental illness show definite international differences. Everywhere, though, mental health care for patients with psychotic illnesses is a "cinderella service," and there is a general move towards care falling increasingly on the family and the community.     

Association of ACE I/D polymorphism with cardiovascular risk factors

Since the identification of an insertion/deletion (I/D) polymorphism in the angiotensin-converting enzyme (ACE) gene, the D allele has been recognized to be associated with cardiovascular disease. Moreover, significant associations of this polymorphism with multiple cardiovascular risk factors have been reported, although some studies failed to detect such associations. In the present study, we investigated the association of the ACE gene polymorphism with the parameters of multiple risk factors in 300 Japanese men who participated in a medical check-up. This investigation detected a significant association of the polymorphism with systolic blood pressure (P=0.007) and diastolic blood pressure (P=0.026), with their highest values in DD subjects and lowest values in II subjects. This significant association is consistent with the proposition that the polymorphism influences blood-pressure variability in men. Furthermore, we investigated the association of the polymorphism with four major disorders (obesity, hyperlipidemia, hypertension, diabetes mellitus) correlated with the risk for cardiovascular disease in the same 300 subjects. This investigation failed to detect any significant association of the polymorphism with each disorder. However, there was a trend that all four disorders were more frequent in ID and DD subjects than in II subjects. We therefore analyzed the association between the ACE gene polymorphism and having at least one of the four disorders in the same population. This analysis detected a significant difference: that ID and DD subjects had at least one of the four disorders more frequently than II subjects (P=0.008; odds ratio=1.89, 95% confidence interval= 1.19-2.99). Taken together, the results of this study are compatible with the proposition that the ACE polymorphism is associated with cardiovascular disease partially mediated through the four disorders in our population.     

Psychiatric and cardiovascular comorbidities in patients with diabetes mellitus starting antiobesity drugs

The aim of the study was to assess whether the baseline risk of psychiatric and cardiovascular disease in patients with diabetes mellitus differs between those starting to use antiobesity drugs and those not starting to use these drugs. A retrospective nested case-control study within the General Practice Research Database (1987-2002) was done. The cohort included all patients with diabetes mellitus (n = 141,164). Information on patient characteristics (general, cardiovascular, and psychiatric characteristics) was extracted from the medical records. Crude odds ratios (ORs) and 95% confidence intervals (CIs) were calculated. A total of 511 patients starting to use antiobesity drugs (cases) and 3,065 controls were included in the study cohort. Starters were younger and more frequently female. Of the starters, 91.8% did not receive any dietary advice before starting treatment. Depression (in the year before index date) was associated with the use of antiobesity drugs (OR 2.2; 95% CI 1.7-2.8), as was anxiety (OR 1.6; 95% CI 1.1-2.4). Of the cases, 25.2% had multiple cardiovascular risk factors (>4) compared to 19.0% of the controls. The baseline risk for psychiatric disorders and cardiovascular disease was found to be higher in patients with diabetes mellitus starting to use antiobesity drugs compared to patients with diabetes mellitus not starting such treatment.     

Prevalence of diabetic and atherosclerotic complications among Mohawk Indians of Kahnawake,PQ.

We surveyed adults with diabetes mellitus and adults without diabetes living in the Mohawk community of Kahnawake, PQ, for clinical characteristics related to vascular disease. People with diabetes were selected from a clinical register; nondiabetic subjects were randomly selected from a community register, with matching for age and sex. The response rates among the two groups were 62% and 39% respectively; groups of 82 and 94 people were obtained. Data were collected by chart review, interview and body measurement. The prevalence rate of ischemic heart disease was 48% for the subjects with diabetes and 22% for those without diabetes. The adjusted odds ratio for development of ischemic heart disease in a person with diabetes was 3.56, for development of cerebrovascular disease 4.57 and for development of peripheral vascular disease 5.51. Logistic regression for macrovascular disease showed that age, sex, smoking, hypertension and obesity could not explain the high rates of complications in the subjects with diabetes. The prevalence rates of ischemic heart disease in adults with and without diabetes are the highest reported in a North American Indian population.     

Socio demographic and lifestyle factors of metabolic syndrome among adult rural indigenous Malaysian population from Perak State,Malaysia

Metabolic syndrome (MetS) is defined as a cluster of known disorders that increase the risk for morbidity and mortality from cardiovascular diseases (CVD) and type 2 diabetes mellitus. This cross sectional study was carried out to estimate the prevalence of MetS using Adult Treatment Panel 3 (ATP 3) classification and socio-demographic and lifestyle factors contributing to metabolic syndrome among rural indigenous Malaysian population from Perak state, Malaysia which included 148 rural Malay and 145 Orang Asli(OA) individuals. This community based cross-sectional study revealed that the prevalence of MetS was significantly higher among Malays (27.7%) as compared to Orang Aslis (13.8%). Overall Prevalence of Metabolic syndrome in the rural indigenous Malaysian population was 20.8%. Prevalence of abdominal obesity and high blood pressure were significantly higher among Malays as compared to OA population. Metabolic syndrome was significantly higher among those above 45 years of age group in overall rural indigenous Malaysian population and among OA. The prevalence of MetS was significantly higher among those who were obese and overweight and among Malays who were regularly taking snacks between meals. There was no significant association between other dietary risk factors, smoking, alcohol use or physical activity with metabolic syndrome.     

Nutrient intake and meal patterns of Micmac indian and Caucasian women in Shubenacadie,NS.

North American Indians have a higher morbidity from gallbladder disease, diabetes mellitus and obesity than other North Americans; this may result from their food intake. Nutrient intake and meal patterns were compared in 120 Micmac Indian and 115 Caucasian women in Shubenacadie, NS. Findings were compared with the Canadian Dietary Standard (CDS) and the Nutrition Canada national and Indian survey reports. The diet of Indian women had higher carbohydrate, lower protein and lower fibre content than that of Caucasian women, who derived a higher percentage of energy from protein and had a higher intake of vitamin A, niacin and ascorbic acid. Overnight fast was longer among Indian women. A high percentage of all women studied reported diets that did not reach the CDS for total energy intake in kilocalories or for calcium, iron, vitamin A, thiamin or riboflavin.     

Slater revisited: 6 year follow up study of patients with medically unexplained motor symptoms

Objective: To investigate psychiatric and neurological morbidity, diagnostic stability, and indicators of prognosis in patients previously identified as having medically unexplained motor symptoms. Design: Follow up study. Setting: National Hospital for Neurology and Neurosurgery, London—a secondary and tertiary referral hospital for neurological disorders. Subjects: 73 patients with medically unexplained motor symptoms admitted consecutively in 1989-91. 35 (48%) patients had absence of motor function (for example, hemiplegia) and 38 (52%) had abnormal motor activity (for example, tremor, dystonia, or ataxia). Main outcome measures: Neurological clinical diagnosis at face to face reassessment by a neurologist and a psychiatric diagnosis after a standardised assessment interview—the schedule for affective disorders and schizophrenia—conducted by a psychiatrist. Results: Good follow up data were available for 64 subjects (88%). Only three subjects had new organic neurological disorders at follow up that fully or partly explained their previous symptoms. 44/59 (75%) subjects had had psychiatric disorders; in 33 (75%) patients, the psychiatric diagnosis coincided with their unexplained motor symptoms. 31/59 (45%) patients had a personality disorder. Three subjects had developed new psychiatric illnesses at follow up, but in only one did the diagnosis account for the previous motor symptoms. Resolution of physical symptoms was associated with short length of symptoms, comorbid psychiatric disorder, and a change in marital status during follow up. Conclusions: Unlike Slater’s study of 1965, a low incidence of physical or psychiatric diagnoses which explained these patients’ symptoms or disability was found. However, a high level of psychiatric comorbidity existed.

Key messages

• Motor symptoms that remain unexplained medically despite thorough investigation are a common clinical problem, but the emergence of a subsequent organic explanation for these symptoms is rare
• The prevalence of coexistent affective and anxiety disorders is high and many patients also have a personality disorder
• Patients with a shorter duration of symptoms and coexistent anxiety or depression are likely to do better at follow up
• Reinvestigation of these patients is both expensive and potentially dangerous and should be avoided where no clear clinical indication exists

     

Psychiatric illness in inpatients with neurological disorders: patients' views on discussion of emotional problems with neurologists.

The prevalence of psychiatric morbidity in inpatients with neurological disorders and the extent to which it is detected by neurologists were measured by using a two stage model of psychiatric assessment and from information recorded in the patients'' medical notes. The prevalence of psychiatric morbidity was estimated as 39%, of which 72% was unrecognised by the neurologists. Only a minority of patients with an uncertain physical diagnosis had a psychiatric illness, showing the error in assuming that a patient''s physical symptoms arise from a psychological disturbance if an organic aetiology cannot be determined. When the patients were interviewed on their discharge from hospital they were divided on whether they had wished to discuss their mood with neurologists while they were in hospital. The reasons that they gave suggested that interactions between patients and doctors and the lack of ward facilities for private consultations with doctors are important determinants of hidden psychiatric morbidity in medical inpatients.     

Measuring the reinforcing strength of abused drugs

Animal models for human diseases are highly valued for their utility in developing new therapies. Animals have long provided suitable platforms for the development of innovative surgical procedures and for the study of disease states that are relatively easy to produce in otherwise healthy animals, such as diabetes or hypertension. Increasingly, new strains of animals susceptible to common human illnesses are being introduced into medical research, promising new inroads into the treatment of a variety of organic disorders. Despite these advances in model development, psychiatric disorders, by and large, remain among the hardest to induce experimentally, and the search for reasonable animal procedures to study diseases of the mind is an ongoing challenge for experimental biologists. An exception to this limitation, however, comes in the study of drug abuse. Major developments in this area of research over the last several decades have steadily advanced our ability to identify pharmacological, genetic, and environmental determinants that contribute to the development of drug dependence and addictive behavior.     

Onset of adolescent eating disorders: population based cohort study over 3 years

ObjectiveTo study the predictors of new eating disorders in an adolescent cohort.DesignCohort study over 3 years with six waves.SubjectsStudents, initially aged 14-15 years, from 44 secondary schools in the state of Victoria, Australia.ResultsAt the start of the study, 3.3% (29/888) of female subjects and 0.3% (2/811) of male subjects had partial syndromes of eating disorders. The rate of development of new eating disorder per 1000 person years of observation was 21.8 in female subjects and 6.0 in male subjects. Female subjects who dieted at a severe level were 18 times more likely to develop an eating disorder than those who did not diet, and female subjects who dieted at a moderate level were five times more likely to develop an eating disorder than those who did not diet. Psychiatric morbidity predicted the onset of eating disorder independently of dieting status so that those subjects in the highest morbidity category had an almost sevenfold increased risk of developing an eating disorder. After adjustment for earlier dieting and psychiatric morbidity, body mass index, extent of exercise, and sex were not predictive of new eating disorders.ConclusionsDieting is the most important predictor of new eating disorders. Differences in the incidence of eating disorders between sexes were largely accounted for by the high rates of earlier dieting and psychiatric morbidity in the female subjects. In adolescents, controlling weight by exercise rather than diet restriction seems to carry less risk of development of eating disorders.

Key messages

• Adolescent females who diet at a severe level are 18 times more likely to develop an eating disorder than those who do not diet, and those who diet at a moderate level are five times more likely to develop an eating disorder
• High levels of psychiatric morbidity in females increase the risk of developing eating disorders by sevenfold
• Around two thirds of new cases of eating disorder arise in females who have dieted moderately
• The predominance of eating disorders in females is largely explained by the higher rates of earlier dieting and psychiatric morbidity
• Daily exercise seems to be a less risky strategy for controlling weight in adolescents

     

Substance use and other psychiatric disorders among 100 American Indian patients

One hundred American Indian patients with a Psychoactive Substance Use Disorder (PSUD) were studied with special reference to associated psychiatric disorders. This clinical sample was divided into three groups: PSUD only, PSUD plus an Organic Mental Disorder (OMD), and PSUD plus any other psychiatric disorder. OMD diagnoses included primarily Delirium Tremens and Alcoholic Hallucinosis; cases of Alcohol Amnestic Disorder, Alcohol Dementia, and trauma-induced OMD were also encountered. Other psychiatric disorders included primarily Major Depression and Anxiety Disorder, with smaller numbers of Schizophrenia, Conduct, Sexual, and other Disorders. Demographic and clinical characteristics were compared among these three groups. Those with PSUD + OMD tended to be older, male, and have more DSM-III Axis 3 disorders (American Psychiatric Association 1980) as compared to other patients; those with PSUD + other diagnoses tended to be single and younger. Education and occupational status were not related to the three diagnostic groups. The data were also subjected to MANOVA analysis. Even when corrected for sex, types of substance being abused, Axis 3 health status, and other factors, the three diagnostic groups still bore a significant relationship to age. Those with PSUD + Other psychiatric diagnoses besides OMD tended to be youngest. Those with PSUD-only were intermediate by age, while those with PSUD + OMD tended to be the oldest.     

Karma, reincarnation, and medicine: Hindu perspectives on biomedical research

Prior to the completion of the Human Genome Project, bioethicists and other academics debated the impact of this new genetic information on medicine, health care, group identification, and peoples’ lives. A major issue is the potential for unintended and intended adverse consequences to groups and individuals. When conducting research in, for instance, American Indian and Alaskan native (AI/AN) populations, political, cultural, religious and historical issues must be considered. Among African Americans, the Tuskegee Syphilis Experiment is a reminder of racism and discrimination in this country. The goal of the current study is to understand reasons for participating, or not, in genetic research such as the HapMap project and other genetic/medical research from the perspective of the Indian American community in Houston, Texas. In this article, we report on a topic central to this discussion among Indian Americans: karma and reincarnation. Both concepts are important beliefs when considering the body and what should happen to it. Karma and reincarnation are also important considerations in participation in medical and genetic research because, according to karma, what is done to the body can affect future existences and the health of future descendants. Such views of genetic and medical research are culturally mediated. Spiritual beliefs about the body, tissue, and fluids and what happens to them when separated from the body can influence ideas about the utility and acceptability of genetic research and thereby affect the recruitment process. Within this community it is understood that genetic and environmental factors contribute to complex diseases such as diabetes, hypertension, and cancer; and acknowledgment of the significance of environmental stressors in the production of disease. A commitment to service, i.e. “betterment of humanity,” karmic beliefs, and targeting environmental stressors could be prominent avenues for public health campaigns in this population. This study suggests that minority status does not automatically indicate unwillingness to participate in genetic or medical research. Indian Americans were not skeptical about the potential benefits of biomedical research in comparison to other ethnic minority communities in the United States.     

Metabolic pathways in the periphery and brain: Contribution to mental disorders?

The association between mental disorders and diabetes has a long history. Recent large-scale, well-controlled epidemiological studies confirmed a link between diabetes and psychiatric illnesses. The scope of this review is to summarize our current understanding of this relationship from a molecular perspective. We first discuss the potential contribution of diabetes-associated metabolic impairments to the etiology of mental conditions. Then, we focus on possible shared molecular risk factors and mechanisms. Simple comorbidity, shared susceptibility loci, and common pathophysiological processes in diabetes and mental illnesses have changed our traditional way of thinking about mental illness. We conclude that schizophrenia and affective disorders are not limited to an imbalance in dopaminergic and serotoninergic neurotransmission in the brain. They are also systemic disorders that can be considered, to some extent, as metabolic disorders.     

A polymorphic genomic duplication on human chromosome 15 is a susceptibility factor for panic and phobic disorders

Anxiety disorders are complex and common psychiatric illnesses associated with considerable morbidity and social cost. We have studied the molecular basis of the cooccurrence of panic and phobic disorders with joint laxity. We have identified an interstitial duplication of human chromosome 15q24-26 (named DUP25), which is significantly associated with panic/agoraphobia/social phobia/joint laxity in families, and with panic disorder in nonfamilial cases. Mosaicism, different forms of DUP25 within the same family, and absence of segregation of 15q24-26 markers with DUP25 and the psychiatric phenotypes suggest a non-Mendelian mechanism of disease-causing mutation. We propose that DUP25, which is present in 7% control subjects, is a susceptibility factor for a clinical phenotype that includes panic and phobic disorders and joint laxity.     

Association of monthly frequencies of diverse diseases in the calls to the public emergency service of the city of Buenos Aires during 1999–2004 with meteorological variables and seasons

This work aims to study associations between monthly averages of meteorological variables and monthly frequencies of diverse diseases in the calls to the public ambulance emergency service of the city of Buenos Aires during the years 1999–2004. Throughout this time period no changes were made in the classification codes of the illnesses. Heart disease, arrhythmia, heart failure, cardiopulmonary arrest, angina pectoris, psychiatric diseases, stroke, transient ischemic attack, syncope and the total number of calls were analyzed against 11 weather variables and the four seasons. All illnesses exhibited some seasonal behavior, except cardiorespiratory arrest and angina pectoris. The largest frequencies of illnesses that exhibited some association with the meteorological variables used to occur in winter, except the psychiatric cases. Heart failure, stroke, psychiatric diseases and the total number of calls showed significant correlations with the 11 meteorological variables considered, and the largest indices (absolute values above 0.6) were found for the former two pathologies. On the other side, cardiorespiratory arrest and angina pectoris revealed no significant correlations and nearly null indices. Variables associated with temperature were the meteorological proxies with the largest correlations against diseases. Pressure and humidity mostly exhibited positive correlations, which is the opposite of variables related to temperature. Contrary to all other diseases, psychiatric pathologies showed a clear predominance of positive correlations. Finally, the association degree of the medical dataset with recurrent patterns was further evaluated through Fourier analysis, to assess the presence of statistically significant behavior. In the Northern Hemisphere high morbidity and mortality rates in December are usually assigned to diverse factors in relation to the holidays, but such an effect is not observed in the present analysis. There seems to be no clearly preferred meteorological proxy among the different types of temperatures used. It is shown that the amount of occurrences depends mainly on season rather on its strength quantified by temperature.     

An evaluation of the multidisciplinary approach to psychiatric diagnosis in elderly people.

OBJECTIVE--To determine the accuracy of psychiatric diagnoses made by two community psychogeriatric teams operating a multidisciplinary assessment procedure. DESIGN--Comparison of team diagnosis with independent formal assessment and consensus diagnosis by research psychiatrists. SETTING--Two community psychogeriatric teams with similar operational policies in an inner London health district. SUBJECTS--100 people aged 65-90 (70 women) newly referred to the teams. MAIN OUTCOME MEASURES--Concordance between team and research diagnoses. RESULTS--Agreement between team and research diagnoses ranged from 90% to 99% for the specific psychiatric disorders studied. There was no significant difference between medical and non-medical team members in their diagnostic performance compared with the research psychiatrists. Increased diagnostic accuracy by team members was associated with longer experience of team working, regardless of the team members'' professional background. CONCLUSIONS--The multidisciplinary approach to the assessment of referrals to these community teams for the elderly is not associated with misdiagnosis of psychiatric disorder.     

Depression and other psychiatric morbidity in carers of elderly people living at home.

OBJECTIVE--To describe the mental health of a community sample of carers of elderly people with dementia, depression, or physical disability and to compare that with the mental health of other adults living in the household and of those living alone. DESIGN--Assessment of psychiatric morbidity and physical disability with standardised questionnaire in randomly selected enumeration districts; subjects were interviewed at home. SETTING--London Borough of Islington. SUBJECTS--700 people aged > or = 65 and other coresidents. MAIN OUTCOME MEASURE--Depression measured with standardised interview. RESULTS--The prevalence of depression was not significantly higher in carers overall (15%) than in coresidents (11%). Being a woman carer was a significant predictor of psychiatric illness. Depression was more common in the carers of people with a psychiatric disorder than in coresidents (24% v 11%, P < 0.05) and in those living alone (19%). Depression was most common (47%) in women carers of people with dementia. CONCLUSION--The increase in psychiatric morbidity reported in carers of people with psychiatric disorders may reflect the lack of a confiding relationship.     

Body fat distribution of children and adolescents in Abeokuta,Southwest Nigeria

Excessive central fat in children and adolescents is a risk factor for cardiovascular and metabolic disorders. This study aimed to compare the body fat distribution patterns of children and adolescents in Abeokuta, Nigeria with international reference standards. Five hundred seventy children aged 5 to 19 years were selected from seven schools using multistage random sampling. Weight, height, triceps and subscapular skinfold thickness (TSF, SSF), and circumference at the waist and hips (WC, HC) were measured. Body mass index (BMI), subscapular:triceps skinfold ratio (STR), waist:hip circumference ratio (WHR), and waist: height ratio (WHtR) were derived. Females had higher mean BMI, TSF, SSF, WC, HC, WHR, and WHtR, while males had significantly higher STR. The mean BMI, WC, TSF, and SSF values were lower for our subjects than for African‐American subjects at all ages. On the other hand, in both sexes, STR was higher among Nigerian than African‐American subjects up to 12 years old. Thereafter the values were similar. The mean WC was similar to those reported for African‐American males up to 8 years, and females up to 7 years of age; thereafter, African‐American had higher values. The prevalence of central obesity using WC and WHtR measures was 4.4% and 5.8%, respectively. There is a need to validate each index against serum lipid profiles and other cardiovascular and metabolic risk factors. Am J Phys Anthropol 150:647–654, 2013. © 2013 Wiley Periodicals, Inc.
