Many were named, but few are current: The Hebeloma of Hesler, Smith, and coauthors

During the 1970s and 1980s, L. R. Hesler and A. H. Smith, alone, together, or Smith with other authors such as V. S. Evenson and D. H. Mitchel, described numerous North American taxa in Hebeloma. With the inclusion of an early work by Smith and a later work by E. Grilli, who described a species based on material from Smith, 130 taxa were described and form the subject of this paper. Apart from two taxa that were (deliberately) invalidly published and two that were illegitimately published, all others are valid and legitimate names. After study of morphology, habitat, and location of collection (based on available material and information) as well as molecular analysis (insofar as this was successful), of these 128 validly published taxa we regard 14 as being current names; the remaining 114 are synonymized with other current names. These 14 species are Hebeloma albomarginatum, H. alpinicola, H. angelesiense, H. caulocystidiosum, H. immutabile, H. incarnatulum, H. kelloggense, H. mackinawense, H. nitidum, H. olympianum, H. parcivelum, H. praeolidum, H. pungens, and H. sporadicum. This brings up the number of currently recognized, validly published, Hebeloma species in America to 72.

Old but not obsolete: A new life for some of Murrill's (Hebeloma) names

William Alphonso Murrill was an American mycologist of the early 20th century. He described 1453 new species of Agaricales, Boletales, and Polyporales. Within these were 44 taxa that he described as Hebeloma or that he recombined into Hebeloma. Additionally, there are five species, of which we are aware, that Murrill described within other genera that should be referred to the genus Hebeloma. A further three species described from northern America by J. P. F. C. Montagne, and transferred to Hebeloma by Saccardo, were commented on by Murrill and not accepted within the genus. These 52 taxa are analyzed here, both morphologically and molecularly, as far as possible. For 18 of his types, internal transcribed spacer (ITS) sequences were generated. For two species (H. harperi and H. subfastibile), which were mixed collections, lectotypes are designated. Twenty-three of the taxa analyzed are Hebeloma, as the genus is recognized today, and six of these (H. australe, H. harperi, H. paludicola, H. subaustrale, H. subfastibile, and H. viscidissimum) are regarded as current, i.e., they are names that should be accepted and used. Hebeloma paludicola is an earlier name for H. hygrophilum, described from Europe. Gymnopilus viscidissimus is synonymous with H. amarellum but has priority and is here recombined into Hebeloma. The remaining 17 Hebeloma taxa are synonymized with other species that have priority. The remaining 29 species belong to a range of genera; molecularly supported were Agrocybe, Cortinarius, Inocybe, Inosperma, Phlegmacium, Pholiota, Pseudosperma, and Pyrrhulomyces. Recombinations and synonymizations are made as appropriate and necessary. The names H. alachuanum and H. vatricosum, respectively Inocybe vatricosa, are considered doubtful and should be avoided.

Species determination using AI machine-learning algorithms: Hebeloma as a case study

The genus Hebeloma is renowned as difficult when it comes to species determination. Historically, many dichotomous keys have been published and used with varying success rate. Over the last 20 years the authors have built a database of Hebeloma collections containing not only metadata but also parametrized morphological descriptions, where for about a third of the cases micromorphological characters have been analysed and are included, as well as DNA sequences for almost every collection. The database now has about 9000 collections including nearly every type collection worldwide and represents over 120 different taxa. Almost every collection has been analysed and identified to species using a combination of the available molecular and morphological data in addition to locality and habitat information. Based on these data an Artificial Intelligence (AI) machine-learning species identifier has been developed that takes as input locality data and a small number of the morphological parameters. Using a random test set of more than 600 collections from the database, not utilized within the set of collections used to train the identifier, the species identifier was able to identify 77% correctly with its highest probabilistic match, 96% within its three most likely determinations and over 99% of collections within its five most likely determinations.

Not (only) poison pies - Hebeloma (Agaricales, Hymenogastraceae) in Mexico

The species of Hebeloma have been little studied in Mexico, but have received attention as edibles and in trials to enhance production of edible fungi and tree growth through inoculation of seedlings with ectomycorrhizal fungi. Here we describe three new species of Hebeloma that are currently known only from Mexico. These species belong to separate sections of the genus: H.ambustiterranum is a member of H.sect.Hebeloma, H.cohaerens belongs to H.sect.Theobromina, while H.magnicystidiatum belongs to H.sect.Denudata. All three species were collected from subtropical pine-oak woodland; all records of H.cohaerens came from altitudes above 2500 m. Hebelomaambustiterranum is commonly sold in the local markets of Tlaxcala as a prized edible mushroom. An additional nine species are reported from Mexico, of which eight are new records for the country: H.aanenii, H.eburneum, H.excedens, H.ingratum, H.neurophyllum, H.sordidulum, H.subaustrale and H.velutipes. First modern descriptions of H.neurophyllum and H.subaustrale, originally described from the USA, are given here.

Revisiting Hebeloma (Hymenogastraceae, Agaricales) in Japan: four species recombined into other genera but three new species discovered

Here, we present the results of studies of Japanese Hebeloma collections. The four species described by Imai as Hebeloma (H. fimicola, H. helvolescens, H. humosum, and H. tomoeae) are not from the genus Hebeloma, but are members of Agrocybe, Homophron, or Pholiota. Recombinations are made. Hebelomacrustuliniforme f. microspermum, described by Hongo, is a synonym of H. nanum. Three species of Hebeloma are described as new to science, all currently known only from Japan. Two of these species, H. asperosporum and H. cinnamomeum, are members of H. sect. Denudata while the third species H. citrisporum belongs to H. sect. Velutipes. Japanese records of H. cavipes, H. eburneum, H. hygrophilum, H. subtortum, and H. velutipes are validated. In total, fifteen species of Hebeloma are confirmed from Japan; this is compared with previous checklists.

96 North American taxa sorted - Peck's Hebeloma revisited

Charles Horton Peck described some 2700 species of North American fungi in the 19th and early 20th centuries. Among these were 31 species that he described as Hebeloma or that later authors recombined into Hebeloma. These 31 taxa have been analyzed morphologically and molecularly, as far as possible. For six of these species, lectotypes are designated. For twelve species, ITS sequences (some partial) were generated. Thirteen of the species analyzed are Hebeloma, as the genus is delimited today. Of these 13, nine are regarded as 'current', i.e. are names that should be accepted and used. Of the remaining four, three are synonymized with earlier Peck species and one with the generic type H. mesophaeum. Numerous Hebeloma species described from America are synonymized with some of Peck's species, such as H. albidulum, H. album, H. colvinii, H. excedens, H. palustre, H. sordidulum, and H. velatum; Peck's H. album, H. palustre, and H. velatum are earlier names for H. fragilipes, H. clavulipes, and H. dunense, respectively. All three names were in current use and described from Europe. The 18 species that are not Hebeloma belong to a range of genera: Agrocybe, Hemistropharia, Inocybe, Inosperma, Naucoria, and Pholiota; three species that were not previously recombined into their respective genera are here recombined and one species, Hebeloma commune is synonymized with Pholiota lenta. Two taxa, that are not Hebeloma, remain unresolved. Sixty later Hebeloma taxa described from North America are revised and synonymized with Peck species and seven with H. mesophaeum, 36 of these supported by ITS (some partial) sequence data. Updates on two species, H. petrakii and H. remyi, from Europe, are also given, and a lectotype and epitype selected for the latter.

Primary neuroendocrine tumor of the pineal gland: a case report

INTRODUCTION

Primary intracranial neuroendocrine tumors are exceedingly rare, with few cases in the literature. We present a case of a primary neuroendocrine carcinoma of the pineal gland, which is the second that has ever been reported.

CASE PRESENTATION

A 53-year-old male patient presented with vomiting, weakness, and headaches. Imaging revealed a lesion in the pineal region, which was surgically resected. This mass was characterized by histology as a neuroendocrine carcinoma, given the presence of neuroendocrine markers and cytokeratin markers with absence of a primary lesion elsewhere on imaging.

CONCLUSIONS

There are currently no guidelines on the management of primary intracranial neuroendocrine tumors. In this case, the patient underwent surgical resection and craniospinal radiotherapy. He subsequently received one cycle of chemotherapy with temozolomide, an alkylating agent, but he unfortunately did not tolerate treatment. A multidisciplinary decision was made along with the patient and his family to focus on palliative care. Eighteen months after the initial presentation, disease recurred in the patient's neck. The patient underwent resection to control the metastases, with a plan to follow with radiotherapy and chemotherapy. Unfortunately, the patient became unwell and died at 21 months after initial diagnosis. This demonstrates a need for continued research and reporting on this uncommon disease entity.

Perceptions of Restrictiveness in Forensic Mental Health: Do Demographic, Clinical, and Legal Characteristics Matter?

Where safe, forensic mental health systems should provide care in the least restrictive environment possible. Doing so can maximize patient autonomy and empowerment while minimizing unnecessary social disconnection and stigmatization. This study investigated whether patients' perceptions of restrictiveness were associated with demographic, clinical, and legal characteristics. The Forensic Restrictiveness Questionnaire (FRQ) was used to measure perceptions of restrictiveness in 235 patients in low-, medium-, and high-secure settings in England. The results showed that restrictiveness scores were significantly higher for patients who experienced an adverse event in the past week or were diagnosed with a personality disorder compared to those with a mental illness. A regression analysis suggested that only diagnosis was predictive of FRQ scores when controlling for perceptions of ward atmosphere and quality of life. Age, length of stay, ethnicity, level of security, legal section, and offence type were not associated with FRQ scores. Future research should investigate the roles that individual symptoms, insight into illness, mood, personality, and expectations of care have in influencing perceptions of restrictiveness.

The UK Government should withdraw from the Convention on the Rights of Persons with Disabilities

Many psychiatrists in the UK may be surprised to find that the Government ratified a convention ten years ago that suggests compulsory mental health treatment be prohibited. The Convention on the Rights of Persons with Disabilities is arguably the most important legal instrument that no one in psychiatry ever discusses, but if moved from ratification to enforcement it would have enormous effect on day-to-day practice. Here, Dr Paul Gosney argues that the convention if enforced would be damaging for the people it aims to protect, whereas Professor Peter Bartlett defends it as a necessary challenge to the inequalities in our current system.

At the Interface Between Paradigms: English Mental Capacity Law and the CRPD

The United Nations Convention on the Rights of Persons with Disabilities (CRPD) is rightly seen as a break from the past in mental capacity law. At the same time, implementation will occur in the specific existing legal and administrative contexts of each State. This article uses English mental capacity law to explore these issues. The English Mental Capacity Act 2005 (MCA) can be considered the best of the "old" paradigm. The article argues that there are continuities between it and a CRPD-compliant approach. These continuities should be built upon. Further, the implementation of the MCA is still in recent memory. The lessons of that implementation will have considerable application to moves toward CRPD compliance. CRPD compliance is not just about specialist stator guardianship régimes. It is also about a myriad of law, currently capacity based, located in specific legal areas such as contract, wills and succession, and criminal law. Reform in these areas will involve not just disability law, but successful integration into those other legal areas, a matter requiring the involvement of those knowledgeable in those other areas. Since change in these areas will involve the removal of disability as a gateway criterion, they will affect the public as a whole, and the thus, determination of the degree and sort of intervention that the broader public will consider appropriate.

Articulating future directions of law reform for compulsory mental health admission and treatment in Hong Kong

This article explores and outlines four possible pathways for law reform in the area of compulsory mental health admission and treatment in Hong Kong: the (i) abolition, (ii) risk of harm, (iii) mental capacity and (iv) consensus pathways. The discussion of each pathway takes into account local challenges in implementation, as well as Hong Kong's international commitments for the protection of rights. In outlining these pathways for reform, the authors intend to also provide a blueprint for regulatory change in other jurisdictions that are in the process of reforming their mental health laws.

The Forensic Restrictiveness Questionnaire: Development, Validation, and Revision

Introduction: Forensic psychiatric care is often practiced in closed institutions. These highly regulated, secure, and prescriptive environments arguably reduce patient autonomy, self-expression, and personhood. Taken together these settings are restrictive as patients' active participation in clinical, organizational, community, and personal life-worlds are curtailed. The consequences of patients' experiences of restrictiveness have not been explored empirically. This study aimed to develop a psychometrically-valid measure of experiences of restrictiveness. This paper presents the development, validation, and revision of the Forensic Restrictiveness Questionnaire (FRQ). Methods: In total, 235 patients recruited from low, medium, and high secure hospitals across England completed the FRQ. The dimensionality of the 56-item FRQ was tested using Principle Axis Factor Analysis and parallel analysis. Internal consistency was explored with Cronbach's α. Ward climate (EssenCES) and quality of life (FQL-SV) questionnaires were completed by participants as indicators of convergent validity. Exploratory Factor Analysis (EFA) and Cronbach's α guided the removal of items that did not scale adequately. Results: The analysis indicated good psychometric properties. EFA revealed a unidimensional structure, suggesting a single latent factor. Convergent validity was confirmed as the FRQ was significantly negatively correlated with quality of life (Spearman's ρ = -0.72) and ward climate (Spearman's ρ = -0.61). Internal consistency was strong (α = 0.93). Forty-one items were removed from the pilot FRQ. The data indicate that a final 15-item FRQ is a valid and internally reliable measure. Conclusion: The FRQ offers a novel and helpful method for clinicians and researchers to measure and explore forensic patients' experiences of restrictiveness within secure hospitals.

Reducing relapse and suicide in bipolar disorder: practical clinical approaches to identifying risk, reducing harm and engaging service users in planning and delivery of care – the PARADES (Psychoeducation, Anxiety, Relapse, Advance Directive Evaluation and Suicidality) programme

Background

Bipolar disorder (BD) costs £5.2B annually, largely as a result of incomplete recovery after inadequate treatment.

Objectives

A programme of linked studies to reduce relapse and suicide in BD.

Design

There were five workstreams (WSs): a pragmatic randomised controlled trial (RCT) of group psychoeducation (PEd) versus group peer support (PS) in the maintenance of BD (WS1); development and feasibility RCTs of integrated psychological therapy for anxiety in bipolar disorder (AIBD) and integrated for problematic alcohol use in BD (WS2 and WS3); survey and qualitative investigations of suicide and self-harm in BD (WS4); and survey and qualitative investigation of service users’ (SUs) and psychiatrists’ experience of the Mental Capacity Act 2005 (MCA), with reference to advance planning (WS5).

Setting

Participants were from England; recruitment into RCTs was limited to certain sites [East Midlands and North West (WS1); North West (WS2 and WS3)].

Participants

Aged ≥ 18 years. In WS1–3, participants had their diagnosis of BD confirmed by the Structural Clinical Interview for theDiagnostic and Statistical Manual of Mental Disorders.

Interventions

In WS1, group PEd/PS; in WS3 and WS4, individual psychological therapy for comorbid anxiety and alcohol use, respectively.

Main outcome measures

In WS1, time to relapse of bipolar episode; in WS2 and WS3, feasibility and acceptability of interventions; in WS4, prevalence and determinants of suicide and self-harm; and in WS5, professional training and support of advance planning in MCA, and SU awareness and implementation.

Results

Group PEd and PS could be routinely delivered in the NHS. The estimated median time to first bipolar relapse was 67.1 [95% confidence interval (CI) 37.3 to 90.9] weeks in PEd, compared with 48.0 (95% CI 30.6 to 65.9) weeks in PS. The adjusted hazard ratio was 0.83 (95% CI 0.62 to 1.11; likelihood ratio testp = 0.217). The interaction between the number of previous bipolar episodes (1–7 and 8–19, relative to 20+) and treatment arm was significant (χ2 = 6.80, degrees of freedom = 2;p = 0.034): PEd with one to seven episodes showed the greatest delay in time to episode. A primary economic analysis indicates that PEd is not cost-effective compared with PS. A sensitivity analysis suggests potential cost-effectiveness if decision-makers accept a cost of £37,500 per quality-adjusted life-year. AIBD and motivational interviewing (MI) cognitive–behavioural therapy (CBT) trials were feasible and acceptable in achieving recruitment and retention targets (AIBD:n = 72, 72% retention to follow-up; MI-CBT:n = 44, 75% retention) and in-depth qualitative interviews. There were no significant differences in clinical outcomes for either trial overall. The factors associated with risk of suicide and self-harm (longer duration of illness, large number of periods of inpatient care, and problems establishing diagnosis) could inform improved clinical care and specific interventions. Qualitative interviews suggested that suicide risk had been underestimated, that care needs to be more collaborative and that people need fast access to good-quality care. Despite SUs supporting advance planning and psychiatrists being trained in MCA, the use of MCA planning provisions was low, with confusion over informal and legally binding plans.

Limitations

Inferences for routine clinical practice from WS1 were limited by the absence of a ‘treatment as usual’ group.

Conclusion

The programme has contributed significantly to understanding how to improve outcomes in BD. Group PEd is being implemented in the NHS influenced by SU support.

Future work

Future work is needed to evaluate optimal approaches to psychological treatment of comorbidity in BD. In addition, work in improved risk detection in relation to suicide and self-harm in clinical services and improved training in MCA are indicated.

Experiences of restrictiveness in forensic psychiatric care: Systematic review and concept analysis

Mentally disordered offenders may be sent to secure psychiatric hospitals. These settings can resemble carceral spaces, employing high levels of security restricting resident autonomy, expression and social interaction. However, research exploring the restrictiveness of forensic settings is sparse. A systematic review was therefore undertaken to conceptualize this restrictiveness. Eight databases were searched for papers that address restrictive elements of secure forensic care in a non-cursory way. Fifty sources (empirical articles and policy documents) were included and subject to thematic analysis to identify 1) antecedent conditions to, 2) characteristic attributes, 3) consequences and 4) 'deviant' cases of the developing concept. The restrictiveness of forensic care was experienced across three levels: individual, institutional and systemic. Restrictiveness was subjective and included such disparate elements as limited leave and grounds access, ownership of personal belongings and staff attitudes. The manner and extent to which these are experienced as restrictive was influenced by two antecedent conditions; whether the purpose of forensic care was to be more caring or custodial and the extent to which residents were perceived to be risky. We argue that there must be a reflexivity from stakeholders between the level of restrictiveness needed to safely provide care in a therapeutic milieu and enable the maximum amount of resident autonomy.

National survey of training of psychiatrists on advance directives to refuse treatment in bipolar disorder

Aims and method To determine features associated with better perceived quality of training for psychiatrists on advance decision-making in the Mental Capacity Act 2005 (MCA), and whether the quality or amount of training were associated with positive attitudes or use of advance decisions to refuse treatment (ADRTs) by psychiatrists in people with bipolar disorder. An anonymised national survey of 650 trainee and consultant psychiatrists in England and Wales was performed. Results Good or better quality of training was associated with use of case summaries, role-play, ADRTs, assessment of mental capacity and its fluctuation. Good or better quality and two or more sessions of MCA training were associated with more positive attitudes and reported use of ADRTs, although many psychiatrists would never discuss them clinically with people with bipolar disorder. Clinical implications Consistent delivery of better-quality training is required for all psychiatrists to increase use of ADRTs in people with bipolar disorder.

Urgently awaiting implementation: The right to be free from exploitation, violence and abuse in Article 16 of the Convention on the Rights of Persons with Disabilities (CRPD)

The Convention on the Rights of Persons with Disabilities (CRPD) enshrines the freedom from exploitation, violence and abuse, a provision, which has hitherto received little attention. Exploring the contents of Article 16, this paper seeks to unpack both the potential for violence prevention as well as the implementation challenges. It situates violence protection within related treaty provisions and touches on specific challenges in institutional care as well as the private realm.

National survey and analysis of barriers to the utilisation of the 2005 mental capacity act by people with bipolar disorder in England and Wales

Background: The Mental Capacity Act (2005) (MCA) provides a legal framework for advance planning for both health and welfare in England and Wales for people if they lose mental capacity, for example, through mania or severe depression.Aims: To determine the proportion of people with bipolar disorder (BD) who utilise advance planning, their experience of using it and barriers to its implementation.Methods: National survey of people with clinical diagnosis of BD of their knowledge, use and experience of the MCA. Thematically analysed qualitative interviews with maximum variance sample of people with BD.Results: A total of 544 respondents with BD participated in the survey; 18 in the qualitative study. 403 (74.1%) believed making plans about their personal welfare if they lost capacity to be very important. A total of 199 (36.6%) participants knew about the MCA. A total 54 (10%), 62 (11%) and 21 (4%) participants made advanced decisions to refuse treatment, advance statements and lasting power of attorney, respectively. Barriers included not understanding its different forms, unrealistic expectations and advance plans ignored by services.Conclusion: In BD, the demand for advance plans about welfare with loss of capacity was high, but utilisation of the MCA was low with barriers at service user, clinician and organisation levels.

Identity, law, policy and Communicating Mental Health

This paper reflects on the special edition, Communicating Mental Health, from the perspective of a legal academic with an interest in the service user rights and in United Nations Convention on the Rights of Persons with Disabilities. It is argued that the special edition demonstrates the breadth of the medical model but also that the medical model remains firmly in place in academic understanding of mental disability. The paper questions what this means for identity formation of people with lived experience of mental disability and how we should conceptualise mental disability in the future.

Hearing Loss in HIV-Infected Children in Lilongwe, Malawi

INTRODUCTION

With improved access to antiretroviral therapy (ART), HIV infection is becoming a chronic illness. Preliminary data suggest that HIV-infected children have a higher risk of disabilities, including hearing impairment, although data are sparse. This study aimed to estimate the prevalence and types of hearing loss in HIV-infected children in Lilongwe, Malawi.

METHODS

This was a cross-sectional survey of 380 HIV-infected children aged 4-14 years attending ART clinic in Lilongwe between December 2013-March 2014. Data was collected through pediatric quality of life and sociodemographic questionnaires, electronic medical record review, and detailed audiologic testing. Hearing loss was defined as >20 decibels hearing level (dBHL) in either ear. Predictors of hearing loss were explored by regression analysis generating age- and sex-adjusted odds ratios. Children with significant hearing loss were fitted with hearing aids.

RESULTS

Of 380 patients, 24% had hearing loss: 82% conductive, 14% sensorineural, and 4% mixed. Twenty-one patients (23% of those with hearing loss) were referred for hearing aid fitting. There was a higher prevalence of hearing loss in children with history of frequent ear infections (OR 7.4, 4.2-13.0) and ear drainage (OR 6.4, 3.6-11.6). Hearing loss was linked to history of WHO Stage 3 (OR 2.4, 1.2-4.5) or Stage 4 (OR 6.4, 2.7-15.2) and history of malnutrition (OR 2.1, 1.3-3.5), but not to duration of ART or CD4. Only 40% of caregivers accurately perceived their child's hearing loss. Children with hearing impairment were less likely to attend school and had poorer emotional (p = 0.02) and school functioning (p = 0.04).

CONCLUSIONS

There is an urgent need for improved screening tools, identification and treatment of hearing problems in HIV-infected children, as hearing loss was common in this group and affected school functioning and quality of life. Clear strategies were identified for prevention and treatment, since most hearing loss was conductive in nature, likely due to frequent ear infections, and many children with hearing loss qualified for hearing aids. Screening strategies need to be developed and tested since caregivers were not reliable at identifying hearing loss, and often mis-identified children with normal hearing as having hearing loss. Children with frequent ear infections, ear drainage, TB, severe HIV disease, or low BMI should receive more frequent ear assessments and hearing evaluations.

Litigation Friends or Foes? Representation of 'P' before the Court of Protection

This article argues that, properly analysed, the common law and the European Convention on Human Rights (ECHR) march hand in hand with the provisions of the Mental Capacity Act 2005 (MCA 2005) so as to impose a set of requirements on litigation friends acting for the subject of applications of proceedings before the Court of Protection ('P') which are very different to those currently understood by practitioners and the judiciary. The authors examine critically current practice and procedures and provide a set of proposals for reforms.

Clinical language fMRI with real-time monitoring in temporal lobe epilepsy: online processing methods

The increasing demand for clinical fMRI data has resulted in a need to translate research methods to clinical use. Referrals for language lateralization prior to epilepsy surgery are becoming more common, but time constraints make this unachievable in many busy neuroimaging departments. This study examines whether a single covert verbal fluency paradigm with real-time monitoring and online processing (BrainWave) could replace conventional offline processing (SPM) for the purpose of establishing expressive language dominance prior to epilepsy surgery. We analyzed language fMRI results of 30 patients (17 female; 24 right-handed; median age: 30.5) with temporal lobe epilepsy. Concordance between visual assessment of SPM and BrainWave was 92.8%. Lateralization indices correlated closely with visual assessments of lateralization with a concordance of 85.7%. BrainWave provided a real-time, fast and accurate display of language lateralization easily applied in a clinical setting using only online image processing.

'Appropriate' medical treatment: what's in a word?

Following the amendments in the 2007 Act, there were several revisions made focusing largely on community treatment orders and deprivation of liberty of persons lacking capacity. One of the amendments included a requirement that 'appropriate treatment' be 'available' for compulsion to be imposed in a variety of contexts, most notably admission for treatment under section 3. The definition of appropriate medical treatment within the Act appears largely circular, and therefore of little assistance. The Code of Practice provides some guidance but does little to add to the statutory language. In terms of jurisprudence, there are three reported cases concerning the provision. These cases are analysed and their significance is discussed in an attempt to formulate a clearer definition for appropriate medical treatment.

'The necessity must be convincingly shown to exist': standards for compulsory treatment for mental disorder under the Mental Health Act 1983

Current English law has few controls on the involuntary treatment of persons detained under the Mental Health Act 1983. In 2001, R (Wilkinson) v. Broadmoor Special Hospital Authority provided some hope that, in conjunction with the Human Rights Act and the European Convention on Human Rights (ECHR), meaningful substantive and procedural standards for compulsory psychiatric treatment might be developed, but that hope has not been fulfilled. Using Wilkinson and the ECHR jurisprudence as a starting point, this article considers when, if at all, compulsory psychiatric treatment might be justified. In particular, it considers the difference between the 'appropriateness' standard of the English legislation and the ECHR requirement of 'therapeutic necessity', the requirements for appropriate procedure and appropriate legislative clarity, how the courts should deal with disagreements among treating physicians, and the relevance of the capacity and best interests of the detained person.

Mental health service users' and practitioners' experiences of engagement in assertive outreach: a qualitative study

Assertive outreach services have been central to community mental health policy within the UK. These multidisciplinary teams were established to engage with service users who have severe and enduring mental health problems and have found traditional community services unable to meet their needs. Mental health nurses have a pivotal role in these multidisciplinary teams, yet the nature of these relationships from the perspective of those who work in and receive care is poorly understood. This study set out to explore the nature and meaning of engagement for practitioners and service users within assertive outreach services. A qualitative approach, informed by philosophical hermeneutics, underpinned the study. Participants were recruited from a single assertive outreach team in the UK. To be eligible for the study, mental health practitioners needed to be employed within the assertive outreach team. All service users residing in the community and receiving care from the team were also eligible for inclusion. In total 14 interviews were conducted with mental health practitioners and 13 with service users. Data analysis was informed by Turner's method. Four themes emerged from the data; contact, dialogue, transformation and shared understanding. Meaningful engagement was found to manifest itself through experiences such as providing and receiving practical assistance, having a genuine two-way conversation and valuing the experiences and personal attributes of the other person. The findings indicate that engagement is an active, dynamic and skilled process, which leads practitioners and service users to transform together to create a new relationship.

Detection of methicillin-resistant Staphylococcus aureus (MRSA) in backyard pigs and their owners, Michigan, USA

Methicillin-resistant Staphylococcus aureus (MRSA) have been reported in commercially raised pigs and their human handlers, raising concerns of zoonotic transmission. To determine whether MRSA in backyard-raised pigs is commonly transmitted to their human owners, a matched study of this type of pigs and their owners was conducted in selected counties in Michigan. Nasal swabs from matched owner-pig pairs (n = 50 pairs) with a few unmatched pig (n = 3) and human (n = 4) samples were collected and processed using standard isolation and identification protocols. No matched owner-pig pair was found; however, MRSA was isolated from 1/54 (1.9%) human samples and 2/53(3.8%) of the pigs. The single human isolate was not strain type USA100-1100 by pulsed-field gel electrophoresis (PFGE), was sequence type (ST) 8 by multilocus sequence typing (MLST), possessed SCCmec type IVb and agr I and was negative for the Panton-Valentine leukocidin (PVL) toxin gene. The two pig isolates were indistinguishable by PFGE (not USA100-1100), and both isolates were ST5 by MLST, possessed SCCmec type III and agr II and were negative for the PVL gene. Persons raising backyard swine from the selected Michigan counties had MRSA carriage rates similar to that of the general US population, suggesting that their avocational pig exposure did not increase their risk of MRSA.

Mental health law in the community: thinking about Africa

The new United Nations Convention on the Rights of Persons with Disabilities creates a new paradigm for mental health law, moving from a focus on institutional care to a focus on community-based services and treatment. This article considers implementation of this approach in Africa.

Construction of titanium cranioplasty plate using craniectomy bone flap as template

In recent times a steady rise in cranioplasty operations has been noted because of increasing utilisation of decompressive craniectomy for trauma as well as stroke patients. A variety of techniques have been utilised for cranioplasty, with their own benefits and limitations. Titanium cranioplasty is one of the well-established and widely used techniques, with most centres utilising computer-assisted reconstruction for manufacture of titanium plates. In this paper we present a novel method for making titanium cranioplasty plates using the craniectomy bone flap as a template and the results of our experience. To date we have performed 51 cranioplasties using this method. The surgical results have been comparable to those obtained using the computer-assisted model technique. The construction cost for titanium cranioplasty plates using this method has been pound 360 cheaper per plate compared with the computer-assisted method. In addition, the CT workload and radiation exposure have been reduced.

A review of the literature on the historical development of community mental health services in the United Kingdom

Community mental health encompasses a diverse range of statutory, voluntary and informal care services. However, little has been written about how changes in policy, legislation and philosophies throughout time impact on the service user experience of mental health care today. The purpose of this paper was to review the literature using systematic approaches and address the question: 'How have historical factors influenced the development of community mental health care in the United Kingdom?' Following a comprehensive literature search, we included 70 texts. Owing to the difficulties of classifying historical texts numerically, two themes were identified: (1) changing perspectives towards mental illness and the mentally ill; and (2) the complexities of mental health care provision. We structured the review around these themes. A narrative approach was used to illustrate the diversity within the identified texts. In response to the review question, an exploration of the historical literature demonstrates that some form of community care has always been evident. It also suggests that over time different philosophical ideas have influenced mental health policy and service structure. These have in turn shaped the care a service user receives when they come into contact with mental health professionals.

Quinupristin-dalfopristin resistance in Enterococcus faecium isolates from humans, farm animals, and grocery store meat in the United States

Three hundred sixty-one quinupristin-dalfopristin (Q-D)-resistant Enterococcus faecium (QDREF) isolates were isolated from humans, turkeys, chickens, swine, dairy and beef cattle from farms, chicken carcasses, and ground pork from grocery stores in the United States from 1995 to 2003. These isolates were evaluated by pulsed-field gel electrophoresis (PFGE) to determine possible commonality between QDREF isolates from human and animal sources. PCR was performed to detect the streptogramin resistance genes vatD, vatE, and vgbA and the macrolide resistance gene ermB to determine the genetic mechanism of resistance in these isolates. QDREF from humans did not have PFGE patterns similar to those from animal sources. vatE was found in 35%, 26%, and 2% of QDREF isolates from turkeys, chickens, and humans, respectively, and was not found in QDREF isolates from other sources. ermB was commonly found in QDREF isolates from all sources. Known streptogramin resistance genes were absent in the majority of isolates, suggesting the presence of other, as-yet-undetermined, mechanisms of Q-D resistance.

Localization and physical property experiments conducted by Opportunity at Meridiani Planum

The location of the Opportunity landing site was determined to better than 10-m absolute accuracy from analyses of radio tracking data. We determined Rover locations during traverses with an error as small as several centimeters using engineering telemetry and overlapping images. Topographic profiles generated from rover data show that the plains are very smooth from meter- to centimeter-length scales, consistent with analyses of orbital observations. Solar cell output decreased because of the deposition of airborne dust on the panels. The lack of dust-covered surfaces on Meridiani Planum indicates that high velocity winds must remove this material on a continuing basis. The low mechanical strength of the evaporitic rocks as determined from grinding experiments, and the abundance of coarse-grained surface particles argue for differential erosion of Meridiani Planum.

Localization and physical properties experiments conducted by Spirit at Gusev Crater

The precise location and relative elevation of Spirit during its traverses from the Columbia Memorial station to Bonneville crater were determined with bundle-adjusted retrievals from rover wheel turns, suspension and tilt angles, and overlapping images. Physical properties experiments show a decrease of 0.2% per Mars solar day in solar cell output resulting from deposition of airborne dust, cohesive soil-like deposits in plains and hollows, bright and dark rock coatings, and relatively weak volcanic rocks of basaltic composition. Volcanic, impact, aeolian, and water-related processes produced the encountered landforms and materials.
