Needs for care from a demand led community psychiatric service: a study of patients with major mental illness.

OBJECTIVE--To measure needs for care of patients aged 18-65 years with major mental illness. DESIGN. Identification of everyone in one area seen by a health professional within the previous five years because of a psychotic disorder. Interview of a one in three sample of patients and their main carers with the cardinal needs schedule. SETTING--Hamilton, a socially deprived district of Scotland. SUBJECTS--71 subjects were interviewed from the original sample of 263 patients. MAIN OUTCOME MEASURES--"Cardinal problems" in seven clinical and eight social areas of functioning; these are defined as problems requiring action. "Needs"-cardinal problems for which suitable interventions exist but have not been tried recently. RESULTS--High levels of morbidity were found. 30 interviewed patients (42%; 95% confidence interval 31% to 54%) had one or more clinical needs. 35 (49%; 38% to 61%) had one or more social needs. Skills to deal with all but seven needs in the sample were available at the time of investigation. Patients not being seen by the community mental health team were similar in severity and levels of need to those who were on the community team''s caseload. Care was unequivocally and severely inadequate for four patients. Shortcomings in service delivery usually arose from failure to monitor some patients at home. Problems were not due to shortage of acute psychiatric beds nor the absence of an elaborate assertive community care team. CONCLUSIONS--Systematic assessment of needs with research instruments can give valuable insights into the successes and failures of community care of people with major mental illness. Most needs could be dealt with in these patients but in our area (and probably most other parts of the United Kingdom) this would entail diversion of resources from people with less severe disorders.     

Cloning of prepronociceptin has led to the discovery of other biologically active peptides

Among the opioid receptors family, the cloning of the mu, kappa and delta receptors was followed by that of another member, named ORL1 (Opiate Receptor Like 1). In spite of obvious homologies with the mu, kappa and delta receptors, ORL1 does not display a relevant affinity for the endogenous ligands of these former receptors (beta endorphin, enkephalins, dynorphin A...). This observation has prompted to search for an endogenous ligand of ORL1. A heptadecapeptide which fulfils this function, with a nanomolar affinity, has been found. It was named either nociceptin or orphanin FQ. It demonstrates, according either to the dose or to the route of administration, hyperalgesic, allodynic, antiopioidergic or even analgesic effects. It displays also many behavioural effects, modifying especially locomotion, exploratory behaviour, motivation, anxiety, memory, food intake. Nociceptin results from the cleavage of a large precursor protein, prepronociceptin (PPNOC). In this latter, nociceptin is flanked on its C-terminal region by another peptide which may be regarded either as a heptadecapeptide (NocII), or a bidecapeptide (NocIII) according to the inclusion or not of a fragment constituted by 3 arginine residues. Investigating the functions modulated by NocII, we observed that it stimulates locomotor activity of mice and shortens the forepaws licking latency in the hot plate test (55 degrees C); these effects are not shared by NocIII. The simultaneous administration of NocII and nociceptin resulted in animals put on the hot plate to the appearance of their respective effects, not modified by the presence of the other. A 41 amino acid peptide flanks nociceptin on its N-terminal region in PPNOC. It may be cleaved to generate a heptadecapeptide, named nocistatin on account of its antagonist effect on the hyperalgesia/allodynia induced by nociceptin. Thus, the discovery of ORL1 has led to that of nociceptin, that of its precursor PPNOC, and thereby to that of NocII/NocIII and nocistatin. The functions modulated by these peptides are being investigated whereas their receptors are yet unknown. These multiple targets allow to expect new strategies to modulate their functions.     

Paths to psychiatric care in Hong Kong

The pattern of psychiatric consultation in Hong Kong is examined among 226 patients at a public outpatient clinic and 56 patients at a private psychiatric clinic. The approach to psychiatric services is marked by lengthy delay during which patients get help from their family members or close friends. Arrival at the present psychiatric clinic was diverted through other medical resources, primarily Western-style medical services, and to some extent, traditional Chinese medicine. Individual routes were diverse, characterized by frequent switches among resources especially in the private sector. The nature of the patients' presenting complaints as well as the conceptualization of their initial complaints were multi-faceted, including both psychological and somatic factors. The overall consultation pattern of patients in Hong Kong is compared with other studies on Chinese and Western patients. Questions are raised for further analysis.The study was funded by the United Board for Christian Higher Education in Asia Faculty Research Grant made through Chung Chi College of The Chinese University of Hong Kong.     

Spread of cattle led to the loss of matrilineal descent in Africa: a coevolutionary analysis

Matrilineal descent is rare in human societies that keep large livestock. However, this negative correlation does not provide reliable evidence that livestock and descent rules are functionally related, because human cultures are not statistically independent owing to their historical relationships (Galton''s problem). We tested the hypothesis that when matrilineal cultures acquire cattle they become patrilineal using a sample of 68 Bantu- and Bantoid-speaking populations from sub-Saharan Africa. We used a phylogenetic comparative method to control for Galton''s problem, and a maximum-parsimony Bantu language tree as a model of population history. We tested for coevolution between cattle and descent. We also tested the direction of cultural evolution--were cattle acquired before matriliny was lost? The results support the hypothesis that acquiring cattle led formerly matrilineal Bantu-speaking cultures to change to patrilineal or mixed descent. We discuss possible reasons for matriliny''s association with horticulture and its rarity in pastoralist societies. We outline the daughter-biased parental investment hypothesis for matriliny, which is supported by data on sex, wealth and reproductive success from two African societies, the matrilineal Chewa in Malawi and the patrilineal Gabbra in Kenya.     

The evaluation of chronic psychiatric care

During the past two decades the reduction in the size of the mental hospital population in this country has closely followed statistical predictions for bed requirements both in Canada and in the province of Ontario. The decrease has been most pronounced among chronic non-retarded patients. While these patients are now less evident in hospital statistics, it is suggested that improvements in their state may be more apparent than real, owing to differences in the terminology and numerators employed in presenting mental health statistics. Further, concern has been expressed about the quality of care received by former chronic patients now scattered through the community in a variety of after-care programs. Readmission rates have greatly increased in absolute terms and as a proportion of total admissions. The evaluation of the management of chronic psychiatric patients is discussed.     

DNA methylation in neonates born to women receiving psychiatric care

Prenatal exposure both to maternal psychiatric illness and psychiatric medication has been linked with adverse child outcomes that affect physiological, emotional and psychiatric development. Studies suggest that epigenetic mechanisms, such as DNA methylation, may facilitate these effects. In this report, we explore the association between maternal psychiatric illness and treatment during pregnancy and neonatal DNA methylation patterns in a prospectively-characterized clinical cohort of 201 dyads. Associations between the percent of umbilical cord blood DNA methylated at 27,578 CpG sites and maternal psychiatric diagnosis, symptoms and antidepressant use were evaluated by fitting a separate linear mixed effects model for each CpG site. There were no significant changes in neonatal DNA methylation attributable to maternal psychiatric diagnosis or depressive symptoms during pregnancy. Exposure to an antidepressant medication was associated with differential methylation of CpG sites in TNFRSF21 and CHRNA2 (false discovery rate < 0.05), but the average difference in methylation for both CpG sites was less than 3% between each group. The results were not specific to type of antidepressant or duration of the exposure. This study suggests that there are no large effects of maternal psychiatric illness, depressive symptoms or prenatal exposure to antidepressants on neonatal DNA methylation. Delineation of the influence of maternal psychiatric illness and pharmacological exposures on the developing fetuses has critical implications for clinical care during pregnancy.

Development of an index to measure oral health care priority among nursing staff

Objective: To develop an index to measure oral health care priority among nursing staff. Background: Nursing staff, working on hospital wards, at nursing homes and at other facilities, have to deal with oral health care and there are many reports about the low priority that is given to oral health care by nursing staff. It is difficult to measure oral health care priority among nursing staff. A Dental Coping Beliefs Scale (DCBS) index was used in an intervention study and was found to be easy to handle but did not have the ability to reveal significant differences in small study samples. A development process consisting of added items and item numbering by chance was carried out. During this process, different nursing staff test groups were used. The aim was to develop an oral health care priority index that can be used both on hospital wards and at special facilities to measure oral health care priority among nursing staff over time and between groups. Material and methods: Nursing staff at both special facilities and hospital wards and nursing students. Results: It was found that the index, the nursing DCBS, was more stable compared with the version that was used in the initial intervention study. It was also noted that its ability to discriminate between the items was improved. Conclusion: The nursing DCBS index is a suitable tool for use in further studies where the aim is to measure how different nursing staff groups give priority to and allocate responsibility for oral health care, even where study samples are small.     

Acute psychiatric care: approaches to increasing the range of services and improving access and quality of care

Acute services for mental health crises are very important to service users and their supporters, and consume a substantial share of mental health resources in many countries. However, acute care is often unpopular and sometimes coercive, and the evidence on which models are best for patient experience and outcomes remains surprisingly limited, in part reflecting challenges in conducting studies with people in crisis. Evidence on best ap­proaches to initial assessment and immediate management is particularly lacking, but some innovative models involving extended assessment, brief interventions, and diversifying settings and strategies for providing support are potentially helpful. Acute wards continue to be central in the intensive treatment phase following a crisis, but new approaches need to be developed, evaluated and implemented to reducing coercion, addressing trauma, diversifying treatments and the inpatient workforce, and making decision‐making and care collaborative. Intensive home treatment services, acute day units, and community crisis services have supporting evidence in diverting some service users from hospital admission: a greater understanding of how best to implement them in a wide range of contexts and what works best for which service users would be valuable. Approaches to crisis management in the voluntary sector are more flexible and informal: such services have potential to complement and provide valuable learning for statutory sector services, especially for groups who tend to be underserved or disengaged. Such approaches often involve staff with personal experience of mental health crises, who have important potential roles in improving quality of acute care across sectors. Large gaps exist in many low‐ and middle‐income countries, fuelled by poor access to quality mental health care. Responses need to build on a foundation of existing community responses and contextually relevant evidence. The necessity of moving outside formal systems in low‐resource settings may lead to wider learning from locally embedded strategies.
