RESUMO

BACKGROUND: Telehealth (i.e. the use of technology across distance) is widespread in many fields. Although its use for behavioural support for people with intellectual or developmental disabilities (IDD) is emerging, there are no known studies examining stakeholder perceptions of this. METHODS: A four-round Delphi consultation was conducted with 11 professionals and six family carers of children with IDD to generate consensus on what would influence participants' use of telehealth for behavioural support. Data were collected prior to the coronavirus pandemic. RESULTS: Thirty-six items reached consensus for professionals (26 advantages and 10 disadvantages/barriers) and 22 for family carers (8 advantages and 14 disadvantages/barriers). A range of solutions were also identified for the disadvantages/barriers. CONCLUSIONS: Participants were willing to use telehealth for behavioural support. However, disadvantages/barriers need to be addressed, and guidelines relating to the use of telehealth in this field are needed. We report a number of practice recommendations including combining telehealth with in-person supports where possible, incorporating video technologies, and considering client perspectives and confidence with telehealth methodologies.

RESUMO

The deep-ocean carbon cycle is poorly quantified. An abyssal benthic rover was developed to make long time-series measurements of seafloor processes related to organic carbon remineralization and sequestration. Benthic Rover II (BR-II) is an autonomous dual-tracked vehicle that measures bottom water temperature and oxygen concentration, current velocity, and sediment community oxygen consumption (SCOC; respiration). BR-II is programmed to transit with low surface-contact pressure across the seafloor, photograph bottom conditions, and stop regularly to occupy respirometer incubation sites, with deployment periods up to 1 year. Now, continuously operational at a 4000-m station in the northeast Pacific over 5 years, substantial weekly, seasonal, annual, and episodic events have been recorded, which are critical to assessing the deep-ocean carbon cycle. There was a significant increase in phytodetritus cover (P < 0.01) arriving on the seafloor from the overlying water column between 2015 and 2020 that was negatively correlated with bottom water dissolved oxygen concentration (P < 0.01). Over the continuous 5-year monitoring period from November 2015 to November 2020, SCOC was positively correlated with phytodetritus cover (P < 0.01) and increased significantly from 2015 to 2020 (P < 0.01). These results show important influences of biological processes on the carbon cycle. The demonstrated success of BR-II now creates opportunities to expand the long-term monitoring of the deep sea to resolve the coupling of water column and benthic processes key to understanding the oceanic carbon cycle on a planet engulfed in a changing climate.

RESUMO

BACKGROUND: Many family carers find the support they receive in respect of their child's challenging behaviour unhelpful. This study sought to identify carer perceptions of the ways in which support is unhelpful and how it could be more helpful. METHODS: Thirteen mothers, caring for a child with intellectual disability and challenging behaviour, were interviewed. Parental perceptions and concerns regarding support received were investigated. Transcribed interviews were analysed using interpretive phenomenological analysis. RESULTS: Parents reported problems with generic disability services including accessing good services, obtaining relevant information, working relationships with professionals and issues with respite provision. Concerns were also expressed about challenging behaviour-specific provision including ineffective strategies being suggested, an apparent lack of expertise, insufficient input and their child's exclusion from services. CONCLUSIONS: More preventative approaches, more widespread adoption of effective behaviour management and improved partnership between professionals and families appear needed. Increasing family support may be ineffective if not accompanied by greater insight into the factors related to effectiveness and recognition of the role of informal support.

RESUMO

The interaction of ammonia molecules with Lewis acid centers (Ti4+ metal ions) of the (011) surface of rutile TiO2 is investigated by density functional theory in order to understand, from first principle, the nature of acid-base reactions on solid surfaces. Unlike the rutile (110) surface that contains alternating rows of 5-fold and 6-fold Ti atoms, all Ti atoms of the (011) surface are 5-fold coordinated. This surface has shown considerable activity for numerous chemical reactions and is thus an ideal prototype. At 1/2 monolayer coverage, with respect to surface Ti atoms, the adsorption energy is found to be equal to 100 kJ mol-1, and drops to 58 kJ mol-1 at one monolayer coverage. Analysis of the electronic density of states (DOS) revealed information regarding the mode of adsorption. In particular, the nitrogen 3a1 and 2a1 orbitals appear to undergo significant changes upon adsorption, in agreement with photoelectron spectroscopy studies. Dissociative adsorption was also investigated on the same surface. Both NH2(Tis) + H(Os) and NH(Tis) + 2H(Os) modes of dissociative adsorption, where s stands for surface, are found to be less stable than the molecular (non dissociated) adsorption.

RESUMO

BACKGROUND: This study sought to gather information about the characteristics and experiences of children and young people with severe intellectual disabilities and severe challenging behaviour attending 52-week residential special schools. METHOD: Staff of nine schools completed postal questionnaires on the characteristics and experiences of 156 pupils. RESULTS: Those attending residential schools are predominantly male, teenagers and in long-term placements. Most have limited communication skills and autistic spectrum disorders. All display high numbers of challenging behaviours, many of them serious. Children have a greater range and complexity of needs than pupils at day severe learning difficulties (SLD) schools, albeit with some overlap. CONCLUSIONS: Children at 52-week residential schools present needs that both families and local services struggle to meet. Residential placement may provide the intensity of educational input and social support that is required, but may increase the vulnerability of the children. Local alternatives to residential schools should be investigated.

RESUMO

BACKGROUND: This study gathered information about perceptions of family carers of children and young people with developmental disabilities and challenging behaviour of the help, support and treatment received from services and professionals. METHODS: A total of 66 family carers completed postal questionnaires on the nature of, and their satisfaction with, services, professional help and advice received in respect of their family member's challenging behaviour. RESULTS: Most carers were dissatisfied with support and services received. Almost half reported receiving no professional input or none that was helpful. Over two-thirds reported receiving respite care but, in a third of these, the child had been excluded because of challenging behaviour. CONCLUSIONS: Families of children with challenging behaviour often do not receive services and supports that they find helpful. Treatments provided are not always evidence based. The 'rationing' of services creates a danger of inequality of access. We need a more proactive approach to identifying and meeting the need for family support.

RESUMO

INTRODUCTION: The majority of patients with musculo-skeletal problems referred to hospitals in the UK have to wait for months, if not over a year, before finally seeing an orthopaedic surgeon. In Stobhill Hospital, Glasgow, the waiting time for an out-patient appointment was 182 days in 1995, with only 20% of the referrals requiring surgery. The aim of this paper was to reduce the out-patient waiting times based on a co-ordinated team approach. METHODS: An outpatient musculo-skeletal service was developed over a 7-year period at Stobhill Hospital. The traditional consultant-based model, in which the consultant and a trainee saw all new patients referred to the hospital, was gradually replaced with a team approach, based on continuous reconfiguration of the roles of the orthopaedic surgeon and rheumatologist and extending the roles of nurses, physiotherapists and podiatrists. This was achieved by: (i) protocol-based daily triage for all referrals to the most appropriate health professional in the team, by the senior out-patient nursing staff; (ii) allocation of appointments based on clinical priority, with a fast-track for urgent cases; and (iii) improvement of inter-disciplinary communication, facilitating the retraction as well as the extension of traditional roles. RESULTS: Despite the number of GP referrals to the orthopaedic out-patient department at Stobhill nearly doubling in a period of 5 years, the out-patient waiting time decreased by about 50% (90 days from 182 days). This reduction in waiting times improved patient and GP satisfaction levels. We also noticed an improved morale and personal development of the health professionals as they saw patients appropriate to their skills and expertise. CONCLUSION: The team's experience demonstrates the effectiveness of a team approach in tackling what is often seen as the insoluble problem of orthopaedic waiting times. This is based on excellent communication and collaboration, with a clear aim of improving patient care that is evidence based.

RESUMO

This overview is designed to introduce the reader to the broad spectrum of rheumatic syndromes associated with certain fungal and parasitic diseases, brucellosis and leprosy. Musculoskeletal disorders caused by fungi are uncommon and difficult to diagnose, particularly in the early stages. Deep fungal infections involve-in order of frequency-bone, soft tissues and joints. Rare but well-defined rheumatic syndromes occur in a variety of parasitic diseases. Brucellosis remains a major challenge to both human public health and clinical acumen in many countries today. The arthritis of leprosy deserves wider recognition and study as it contributes to disability and may hold clues to the mechanism of inflammation in other rheumatic disorders. All of the above may afflict residents in endemic areas and occasionally appear far from the source of origin in travellers or migrants, and usually cause diagnostic confusion.

RESUMO

OBJECTIVE: To review prevalence of rheumatic disorders in Sub-saharan Africa and in the context of current medical practice in the region assess the need for service and educational provision. DATA SOURCES: Medline, (English, French). Pre-Medline literature review from the 1950's (Current contents). Various conference reports including attendance at all three AFLAR (African League Against Rheumatism) congresses in the 1990's. Author's personal database. All cited references read in full. CONCLUSIONS: The evidence shows rheumatoid arthritis and systemic lupus erythematosus to be increasing in frequency in the indigenous populations of East, Central and South Africa but remaining rare in West Africans. Gout is now more prevalent than ever throughout the subcontinent. HIV has spawned a variety of previously rare spondyloarthropathies (reactive arthritis, psoriatic arthritis, enthesopathy) and changed the epidemiology of pyomyositis and osteomyelitis. Osteoarthritis is a universal problem. Juvenile chronic arthritis is not rare and rheumatic fever is common. Acute and chronic locomotor problems associated with diverse entities such as leprosy, brucellosis, meningococcus, alpha viruses, parasites, fluorosis, rickets and haemoglobinopathies enhance diagnostic diversity and therapeutic and educational requirements. Suggestions made to address the challenge posed by the burden of rheumatic disorders.

RESUMO

Information was collected from 88 staff about their observations of the occurrence and frequency of challenging behaviors in 22 individuals with developmental disabilities with whom they worked. Staff reports suggested considerable variability in challenging behavior in the presence of different staff and, from day to day, in the presence of the same staff. Variability was greater for stereotyped than for aggressive/destructive behavior, and for more frequent behavior. Managers reported generally less challenging behavior than their staff. The validity of the findings was discussed and their implications for research and practice considered.

RESUMO

BACKGROUND: Non-steroidal anti-inflammatory drugs (NSAIDs) are widely used to treat osteoarthritis (OA), though their long-term efficacy is uncertain. We report a comparison of the symptomatic responses to therapy with tiaprofenic acid, indomethacin and placebo over 5 yr. METHODS: A parallel-group, randomized, single-blind trial of patients with knee OA recruited 812 patients from 20 centres; 307 patients received tiaprofenic acid (300 mg b.d.), 202 indomethacin (25 mg t.d.s.) and 303 matching placebo for up to 5 yr. At the end of the parallel-group study, patients receiving tiaprofenic acid or placebo entered a 4-week blinded cross-over study of tiaprofenic acid or placebo, both given for 2 weeks. Assessments were at baseline, 4 weeks, then at 6-month intervals for up to 5 yr in the parallel group study and at 2-week intervals in the cross-over study. They comprised pain scores, duration of morning stiffness, patients' global assessments, paracetamol consumption, adverse reactions, withdrawals and functional outcomes. RESULTS: There were significant falls in overall pain scores in patients receiving NSAIDs compared with placebo at 4 weeks in the parallel-group phase. Thereafter there were no advantages favouring active therapy. In the cross-over phase, pain scores were significantly lower in patients receiving tiaprofenic acid than placebo. Patients who had been receiving long-term tiaprofenic acid showed significant rises in their pain scores when receiving placebo therapy and vice versa. Adverse events were reported by 61% of patients receiving tiaprofenic acid, 63% on indomethacin and 51% on placebo. Potentially severe side-effects were rare; for example, there were only three cases of gastrointestinal bleeding on NSAIDs. The pattern of withdrawal was similar in patients taking NSAIDs and placebo in the parallel-group study; at 48 weeks 53% of the patients remained on tiaprofenic acid, 50% on indomethacin and 54% on placebo. CONCLUSIONS: NSAIDs significantly reduce overall pain over 4 weeks. This short-term responsiveness is retained, and even after several years of therapy with tiaprofenic acid pain scores increased over 2 weeks when it was changed to placebo. Our results do not show long-term benefits from the use of NSAIDs in OA and the majority of patients had persisting pain and disability despite therapy.

RESUMO

OBJECTIVE: To characterize the clinical features of psoriatic arthritis (PsA) in black Zambians and the association of PsA with human immunodeficiency virus (HIV) infection. METHODS: Patients attending an arthritis clinic in a 40 month period who exhibited psoriasiform lesions were assessed clinically and tested for the presence of antibodies to HIV. RESULTS: Of 702 new attendees with inflammatory arthritis 28 were designated as PsA and 27 of these were HIV+. Sixteen patients (60%) at presentation were in WHO clinical stage I (no disease or lymphadenopathy alone) compared to 2 in stage 4 (acquired immune deficiency syndrome, AIDS). Arthritis and psoriasis developed simultaneously in 20 patients. The arthritis is predominantly polyarticular, lower limb, and progressive. Amelioration was noted with onset of AIDS. Psoriasis was commonly an extensive guttate-plaque admixture and nonremittive with onset of AIDS. CONCLUSION: PsA is almost universally associated with HIV infection in black Zambians. The clinical features are similar to those described in Caucasians with HIV associated PsA.

RESUMO

OBJECTIVE: To explore the relationship between spondyloarthropathy (SpA) and infection with the human immunodeficiency virus (HIV) in black Zambians. METHODS: Consecutive patients attending an arthritis clinic in a 30 month period were assessed clinically and tested for the presence of antibodies to HIV. HLA-B27 gene was investigated by polymerase chain reaction and T cell subsets were tested in selected subgroups. RESULTS: Of 595 new attendees, 272 were diagnosed with SpA [130 reactive arthritis (ReA), 128 undifferentiated SpA (uSpA), 13 psoriatic arthritis (PsA), 1 ankylosing spondylitis] and 146 with a reactive type arthritis alone (AA) without preceding clinical trigger infection or SpA features. HIV seroprevalence was 98% in uSpA, 94% PsA, 87% ReA, 64% AA; vs approximately 50% among hospital outpatients and 30% of the adult urban population. Prevalence of SpA is calculated at approximately 180/100,000 in HIV positive and approximately 15/100,000 in HIV negative in the general population. Dysentery was the most common identified trigger. Positive HIV status correlated strongly with SpA features and aggressive sustained disease. At onset 80% of patients were in WHO clinical stage 1 (no disease or lymphadenopathy alone), with a mean CD4+ count of 279/microl. Stage 4 patients had a mean CD4+ count of 60/microl and inactive arthritis. The B27 gene was absent in 30 patients tested. CONCLUSION: ReA is the most common inflammatory joint disorder in black Zambians and is closely linked to HIV infection and not B27, even though our subjects had clinical and radiological characteristics similar to those reported in HLA-B27 positive Caucasians. The changing epidemiology of SpA in this region has important practical and educational implications.

RESUMO

Serum retinol, retinyl palmitate, beta-carotene, cryptoxanthin, lutein, alpha-tocopherol and gamma-tocopherol were measured in 18 captive Humboldt penguins (Spheniscus humboldti) prior to and following the removal of Columbia River (CR) smelt (Thaleichthys pacificus) from the diet. Dietary vitamin A was reduced from 59.8 to 13.5 IU g-1 (dry matter basis) when CR smelt was removed from the diet. Minimal changes were noted in dietary vitamin E. Serum samples Without-CR smelt had significantly lower circulating retinol (1.19 +/- 0.09 vs. 1.94 +/- 0.08 micrograms ml-1) and retinyl palmitate (0.033 +/- 0.012 vs. 0.105 +/- 0.004 microgram ml-1) compared to samples With-CR. The Without-CR smelt diet resulted in increased serum alpha-tocopherol from 26.4 +/- 0.94 to 39.1 +/- 3.72 micrograms ml-1. More serum samples taken Without-CR smelt had detectable levels of gamma-tocopherol than those With-CR smelt. Serum lutein was higher for the samples taken Without versus With-CR smelt. Serum cryptoxanthin did not differ. beta-Carotene was not detected. Data indicate that high levels of dietary vitamin A can affect circulating levels of retinol, retinyl palmitate and vitamin E. Thus, dietary vitamin A and the interrelationship between vitamins A and E should be considered when assessing captive penguins.
