Not too little, not too much: supervisor perceptions of work-readiness of speech-language pathology graduates.

The work-readiness skills and attributes that facilitate healthcare graduates to succeed in their new workplaces are not well defined. In particular, the perspectives of supervisors of graduates in the diverse hospital and community settings of healthcare practice are not well represented in research about work-readiness. Interview data from a case study of twenty-nine supervisors of speech-language pathology graduates was thematically analysed, using Boundary Critique Theory to interpret how the supervisors' understanding of graduate work-readiness was bounded within their understanding of their own system, needs and work environment. The four themes captured the skills that the supervisors perceived as critical for graduate work-readiness: Independence; Attitude; Teamwork; and Learning. A tension was identified within these themes, as supervisors' understanding of work-readiness was bounded by an expectation that graduates are able to moderate how they transfer and apply their graduate skills in their workplace according to the complexity of client needs and the workplace setting. This study increases the visibility of the supervisors' boundaries around what are and are not considered to be work-ready skills, attributes and expectations of a work ready speech-language pathology graduate. This knowledge can be used to facilitate speech-language pathology graduates to successfully transfer, apply and expand these skills as they transition to work, and may be useful for other health professions to explore.

Cascade of care of people diagnosed with HIV in New Zealand between 2006 and 2017.

OBJECTIVES: We estimated the proportion of people reported with HIV in New Zealand between 2006 and 2017, and alive in 2017-2019, who were on antiretroviral therapy (ART) and had a suppressed viral load (VL), and explored their associated characteristics. METHODS: Data were anonymously linked to information on ART and VL within the data collection period (January 2017 to August 2019) using the National Health Index (NHI), Ministry of Health and laboratory datasets, as well as information from clinical specialists. Logistic regression was used to test for associations. Sensitivity analyses were undertaken to estimate the range for the key proportions. RESULTS: Overall, 2355 people were reported with HIV, of whom 116 (5%) had died, 337 (14%) were overseas, and 1701 (72%) were alive in New Zealand; for the remaining 201 (9%) the outcome was unknown. Clinical data were available for 1490 people (87.6%): 1408 (94.5%) were on ART, 11 (< 1%) were not on ART, and for 71 (4.8%) this was unknown. Of those on ART, 1156 (82.1%) had a suppressed VL (< 200 copies/mL), 34 (2.4%) were unsuppressed, and for 218 (15.5%) this was unknown. The estimate of the proportion on ART ranged from 99% to 78%, and those with a suppressed VL ranged from 98% to 78%. CONCLUSIONS: Among people with HIV in New Zealand who are under care, a high proportion were on ART and had suppressed VL. Increasing collection of NHIs and better linkage with laboratory information will reduce the number with unknown information and provide more complete VL results in the future.

Evaluation of an Immunochromatographic Assay for Rapid Detection of Penicillin-Binding Protein 2a in Human and Animal Staphylococcus intermedius Group, Staphylococcus lugdunensis, and Staphylococcus schleiferi Clinical Isolates.

The performance of a rapid penicillin-binding protein 2a (PBP2a) detection assay, the Alere PBP2a culture colony test, was evaluated for identification of PBP2a-mediated beta-lactam resistance in human and animal clinical isolates of Staphylococcus intermedius group, Staphylococcus lugdunensis, and Staphylococcus schleiferi. The assay was sensitive and specific, with all PBP2a-negative and PBP2a-positive strains testing negative and positive, respectively.

Breast cancer as a systemic disease: a view of metastasis.

Breast cancer is now the most frequently diagnosed cancer and leading cause of cancer death in women worldwide. Strategies targeting the primary tumour have markedly improved, but systemic treatments to prevent metastasis are less effective; metastatic disease remains the underlying cause of death in the majority of patients with breast cancer who succumb to their disease. The long latency period between initial treatment and eventual recurrence in some patients suggests that a tumour may both alter and respond to the host systemic environment to facilitate and sustain disease progression. Results from studies in animal models suggest that specific subtypes of breast cancer may direct metastasis through recruitment and activation of haematopoietic cells. In this review, we focus on data implicating breast cancer as a systemic disease.

Socioeconomic outcomes following spinal cord injury and the role of no-fault compensation: longitudinal study.

STUDY DESIGN: Longitudinal cohort study. OBJECTIVES: To estimate socioeconomic and work outcomes over 2 and a half years following spinal cord injury (SCI), and to compare those in receipt of compensation (Accident Compensation Corporation, ACC) and those not. SETTING: People admitted to the two spinal units in 2007-2009 in New Zealand, where there is a unique no-fault compensation scheme for injury. METHODS: Interviews were conducted at ∼6, 18 and 30 months after SCI and data collected on pre-SCI and post-SCI health and socioeconomic characteristics. Poisson regression, quantile regression and a linear mixed model regression were used to compare differences in outcomes. RESULTS: Of the 162 eligible people, 118 (73%) participated and 91(77%) were followed to 30 months; 79% received ACC. Median personal income, self-reported standard of living and household income adequacy all fell slightly to 18 months and then stabilized at 30 months. At that time, 49% had returned to paid work. Among those not eligible for ACC, income fell to less than half the ACC group (P<0.006 after adjustment), and return to work was lower (29% versus 54%). CONCLUSION: The findings that most people retained their economic status and that return to work was relatively high appear to be due to the proportion entitled to the ACC no-fault compensation scheme for injury; with earnings-related compensation, a focus on rehabilitation to work and non-means-tested support services. This situation should mitigate against the downward spiral into poverty and further ill-health.

Diabetes characteristics and long-term management needs in diabetic TB patients.

BACKGROUND: Diabetes mellitus (DM) is common among patients with TB. We assessed DM characteristics and long-term needs of DM-TB patients after completing TB treatment.METHODS: Newly diagnosed TB patients with DM were recruited for screening in a randomised clinical trial evaluating a simple algorithm to improve glycaemic control during TB treatment. DM characteristics, lifestyle and medication were compared before and after TB treatment and 6 months later. Risk of cardiovascular disease (CVD), albuminuria and neuropathy were assessed after TB treatment.RESULTS: Of 218 TB-DM patients identified, 170 (78%) were followed up. Half were males, the mean age was 53 years, 26.5% were newly diagnosed DM. High glycated haemoglobin at TB diagnosis (median 11.2%) decreased during TB treatment (to 7.4% with intensified management and 8.4% with standard care), but this effect was lost 6 months later (9.3%). Hypertension and dyslipidemia contributed to a high 10-year CVD risk (32.9% at month 6 and 35.5% at month 12). Neuropathy (33.8%) and albuminuria (61.3%) were common. After TB treatment, few patients used CVD-mitigating drugs.CONCLUSION: DM in TB-DM patients is characterised by poor glycaemic control, high CVD risk, and nephropathy. TB treatment provides opportunities for better DM management, but effort is needed to improve long-term care.

Late presentation of HIV infection among adults in New Zealand: 2005-2010.

BACKGROUND: Early diagnosis of HIV infection is important for the individual and for disease control. A consensus was recently reached among European countries on definitions of timing of presentation for care: 'Late presentation' refers to entering care with a CD4 count <350 cells/µL or an AIDS-defining event, regardless of the CD4 count. Presentation with 'advanced HIV disease' is a subset having a CD4 count <200 cells/µL and also includes all who have an AIDS-defining event regardless of CD4 count. This study examines timing of presentation in New Zealand from 2005 to 2010. METHODS: Since 2005, information on the initial CD4 cell count has been requested on all people newly diagnosed with HIV infection through antibody testing in New Zealand. Excluded in this analysis were those previously diagnosed overseas or for an immigration medical. RESULTS: A CD4 cell count was provided for 606 (80.3%) of the 755 newly diagnosed adults. Overall, 50.0% were 'late presenters' and 32.0% had 'advanced HIV disease'. Compared with men who have sex with men (MSM), people heterosexually infected were more likely to present late. 'Late presentation' and presentation with 'advanced HIV disease' were significantly more common among older MSM. Maori and Pacific MSM were more likely to present with 'advanced HIV disease'. Compared with European MSM, the age-adjusted relative risks for Maori and Pacific MSM were 2.1 [95% confidence interval (CI) 1.4-3.2] and 2.5 (95% CI 1.2-5.0), respectively. CONCLUSIONS: The high proportion of people presenting late reflects inadequate levels of HIV testing. The lower proportion of late presentations among MSM compared with those heterosexually infected may be explained by a higher proportion of recent locally acquired infections together with different testing patterns.

Evaluation of the impact of direct plating, broth enrichment, and specimen source on recovery and diversity of methicillin-resistant Staphylococcus aureus isolates among HIV-infected outpatients.

We compared recovery of Staphylococcus aureus and methicillin-resistant S. aureus (MRSA) from nasal and groin swab specimens of 600 HIV-infected outpatients by selective and nonselective direct plating and broth enrichment. Swabs were collected at baseline, 6-month, and 12-month visits and cultured by direct plating to mannitol salt agar (MSA) and CHROMagar MRSA (CM) and overnight broth enrichment with subculture to MSA (broth). MRSA isolates were characterized by pulsed-field gel electrophoresis (PFGE), staphylococcal cassette chromosome mec (SCCmec) typing, and PCR for the Panton-Valentine leukocidin. At each visit, 13 to 15% of patients were colonized with MRSA and 30 to 33% were colonized with methicillin-susceptible S. aureus (MSSA). Broth, CM, and MSA detected 95%, 82%, and 76% of MRSA-positive specimens, respectively. MRSA recovery was significantly higher from broth than CM (P ≤ 0.001) or MSA (P ≤ 0.001); there was no significant difference in recovery between MSA and CM. MSSA recovery also increased significantly when using broth than when using MSA (P ≤ 0.001). Among specimens collected from the groin, broth, CM, and MSA detected 88%, 54%, and 49% of the MRSA-positive isolates, respectively. Broth enrichment had a greater impact on recovery of MRSA from the groin than from the nose compared to both CM (P ≤ 0.001) and MSA (P ≤ 0.001). Overall, 19% of MRSA-colonized patients would have been missed with nasal swab specimen culture only. USA500/Iberian and USA300 were the most common MRSA strains recovered, and USA300 was more likely than other strain types to be recovered from the groin than from the nose (P = 0.05).

Methicillin-resistant Staphylococcus aureus colonization in HIV-infected outpatients is common and detection is enhanced by groin culture.

SUMMARYAlthough high rates of clinical infection with methicillin-resistant Staphylococcus aureus (MRSA) have been reported in HIV-infected adults, data on MRSA colonization are limited. We enrolled HIV-infected adults receiving care at the Atlanta VA Medical Center. Swabs from each participant's nares and groin were cultured with broth enrichment for S. aureus. Of 600 HIV-infected adults, 79 (13%) were colonized with MRSA and 180 (30%) with methicillin-susceptible S. aureus. MRSA pulsed-field gel electrophoresis types USA300 (n=44, 54%) and USA500/Iberian (n=29, 35%) predominated. Inclusion of groin swabs increased MRSA detection by 24% and USA300 detection by 38%. In multivariate analysis, MRSA colonization compared to no MRSA colonization was associated with a history of MRSA clinical infection, rarely or never using condoms, and contact with prisons and jails. In summary, the prevalence of MRSA colonization was high in this study of HIV-infected adults and detection of USA300 was enhanced by groin culture.

Educational counselling of patients with combined TB and diabetes mellitus: a randomised trial.

SETTING: Newly diagnosed pulmonary TB with diabetes mellitus (DM) comorbidity attending clinics in Bandung City, Indonesia. OBJECTIVE: To describe the effect of educational counselling on patients' knowledge about TB (transmission, treatment, risk factors) and DM (symptoms, treatment, complications, healthy lifestyle), adherence to medication, and to assess characteristics associated with knowledge. DESIGN: All patients received counselling and were then randomised to either structured education on TB-DM, combined with clinical monitoring and medication adjustment (intervention arm), or routine care (control arm). Knowledge and adherence were assessed using a questionnaire. RESULTS: Baseline and 6-month questionnaires were available for 108 of 150 patients randomised (60/76 in the intervention arm and 48/74 in the control arm). Patients knew less about DM than about TB. There was no significant difference in the proportion with knowledge improvement at 6 months, both for TB (difference of differences 14%; P = 0.20) or for DM (10%; P = 0.39) between arms. Intervention arm patients were more likely to adhere to taking DM medication, with fewer patients reporting ever missing oral DM drugs than those in the control arm (23% vs. 48%; P = 0.03). Higher education level was associated with good knowledge of both TB and DM. CONCLUSIONS: Structured education did not clearly improve patients' knowledge. It was associated with better adherence to DM medication, but this could not be attributed to education alone. More efforts are needed to improve patients' knowledge, especially regarding DM.

CONTEXTE: Patients atteints de diabète sucré (DM) ayant récemment reçu un diagnostic de TB pulmonaire consultant dans les cliniques de la ville de Bandung, Indonésie. OBJECTIF: Décrire l'effet de conseils éducatifs sur les connaissances des patients en matière de TB (transmission, traitement, facteurs de risque), de DM (symptômes, traitement, complications, mode de vie sain) et d'observance thérapeutique, et évaluer les caractéristiques associées à ces connaissances. MÉTHODE: Tous les patients ont reçu des conseils et ont ensuite été randomisés dans l'un des deux groupes suivants : programme d'éducation structuré sur la TB-DM associé à un suivi clinique et à un ajustement thérapeutique (groupe d'intervention) ou prise en charge de routine (groupe témoin). Les connaissances et l'observance ont été évaluées par questionnaire. RÉSULTATS: Les questionnaires administrés à l'inclusion et à 6 mois étaient disponibles pour 108 des 150 patients randomisés (60/76 dans le groupe d'intervention et 48/74 dans le groupe témoin). Les connaissances des patients étaient moins bonnes sur le DM que sur la TB. Aucune différence significative n'a été observée entre les groupes dans la proportion de patients dont les connaissances s'étaient améliorées à 6 mois, tant pour la TB (différence des différences 14% ; P = 0,20) que pour le DM (10% ; P = 0,39). Les patients du groupe d'intervention étaient plus susceptibles d'observer correctement leur traitement antidiabétique. Moins de patients ont en effet rapporté avoir manqué une dose de leur traitement antidiabétique oral par rapport au groupe témoin (23% vs. 48% ; P = 0,03). Un niveau d'éducation plus élevé a été associé à de bonnes connaissances sur la TB et le DM. CONCLUSIONS: Le programme d'éducation structuré n'a pas amélioré de manière évidente les connaissances des patients. Ce programme a été associé à une meilleure observance du traitement antidiabétique, mais cela n'a pas pu être attribué au seul programme d'éducation. Davantage d'efforts sont nécessaires pour améliorer les connaissances des patients, notamment sur le DM.

Early chest X-ray in persons with presumptive tuberculosis increases Xpert® MTB/RIF diagnostic yield and efficiency.

Adult presumptive tuberculosis (TB) patients (n = 1690) were screened for TB using a questionnaire, chest X-ray (CXR) and sputum microscopy for acid-fast bacilli (AFB); Mycobacterium tuberculosis culture was performed for 74% of the patients and Xpert® MTB/RIF was done for 17.2%. Among patients recruited, 943 (55.8%) were diagnosed with TB, of whom 870 (92.3%) were bacteriologically confirmed and 73 (7.7%) were clinically diagnosed on the basis of CXR. Using CXR prior to culture or Xpert testing reduces the number needed to screen from 7.6 to 5.0. Using CXR to triage for culture or Xpert testing reduces the number of missed cases and increases the efficiency of culture and Xpert testing.

Des patients adultes présumés atteints de TB (n = 1690) ont été dépistés à l'aide d'un questionnaire, d'une radiographie pulmonaire (CXR) et d'une microscopie de crachats à la recherche des bacilles acido-alcoolo-résistants; une culture de Mycobacterium tuberculosis a été réalisée chez 74% des patients et un test Xpert® MTB/RIF, chez 17,2%. Parmi les patients recrutés, 943 (55,8%) ont eu un diagnostic de TB, dont 870 (92,3%) ont été confirmés par bactériologie et 73 (7,7%) ont été diagnostiqués sur la CXR. Recourir à la CXR avant la culture ou le test Xpert réduit le nombre requis pour dépister un cas de 7,6 à 5,0. L'utilisation de la CXR pour le triage avant la culture ou le test Xpert réduit les cas manqués et augmente l'efficacité de l'utilisation de la culture et de l'Xpert.

Se investigó de la tuberculosis (TB) en pacientes adultos con presunción clínica de la enfermedad (n = 1690) mediante un cuestionario, la radiografía de tórax (CXR) y la baciloscopia del esputo; se practicó el cultivo para Mycobacterium tuberculosis en 74% de los pacientes y la prueba Xpert® MTB/RIF en 17,2%. De los pacientes que participaron se diagnosticó la TB en 943 (55,8%), de los cuales 870 (92,3%) con confirmación bacteriológica y 73 (7,7%) con diagnóstico clínico a partir de la CXR. El hecho de realizar la CXR o la prueba Xpert antes del cultivo disminuye de 7,6 a 5,0 el número de pacientes que deben someterse a detección. El uso de la CXR para seleccionar los casos en que se debe practicar el cultivo o la prueba Xpert disminuye los casos pasados por alto y aumenta la eficiencia del uso del cultivo y la prueba Xpert.

Towards accurate residue-residue hydrophobic contact prediction for alpha helical proteins via integer linear optimization.

A new optimization-based method is presented to predict the hydrophobic residue contacts in alpha-helical proteins. The proposed approach uses a high resolution distance dependent force field to calculate the interaction energy between different residues of a protein. The formulation predicts the hydrophobic contacts by minimizing the sum of these contact energies. These residue contacts are highly useful in narrowing down the conformational space searched by protein structure prediction algorithms. The proposed algorithm also offers the algorithmic advantage of producing a rank ordered list of the best contact sets. This model was tested on four independent alpha-helical protein test sets and was found to perform very well. The average accuracy of the predictions (separated by at least six residues) obtained using the presented method was approximately 66% for single domain proteins. The average true positive and false positive distances were also calculated for each protein test set and they are 8.87 and 14.67 A, respectively.

Development and implementation of evidence-based laboratory safety management tools for a public health laboratory.

We developed an evidence-based continuous quality improvement (CQI) cycle for laboratory safety as a method of utilizing survey data to improve safety in a public health laboratory setting. • Expert Opinion: The CQI cycle begins with the solicitation of laboratory staff input via an annual survey addressing potential chemical, physical and radiological hazards associated with multiple laboratory activities. The survey collects frequency, severity and exposure data related to these activities in the context of the most pathogenic organisms handled at least weekly. • Gap Analysis: Step 2 of the CQI cycle used survey data to identify areas needing improvement. Typically, the traditional two-dimensional risk assessment matrix is used to prioritize mitigations. However, we added an additional dimension - frequency of exposure - to create three-dimensional risk maps to better inform and communicate risk priorities. • Mitigation Measures: Step 3 of the CQI cycle was to use these results to develop mitigations. This included evaluating the identified risks to determine what risk control measures (elimination, substitution, engineering, administrative or PPE) were needed. In the 2016 iteration of the CQI cycle described here, all mitigations were based on administrative controls. • Evaluation and Feedback: The last step of the CQI cycle was to evaluate the inferred effects of interventions through subsequent surveys, allowing for qualitative assessment of intervention effectiveness while simultaneously restarting the cycle by identifying new hazards. Here we describe the tools used to drive this CQI cycle, including the survey tool, risk analysis method, design of interventions and inference of mitigation effectiveness.

Point of care HbA1c level for diabetes mellitus management and its accuracy among tuberculosis patients: a study in four countries.

BACKGROUND: Diabetes mellitus (DM) is common among tuberculosis (TB) patients and often undiagnosed or poorly controlled. We compared point of care (POC) with laboratory glycated haemoglobin (HbA1c) testing among newly diagnosed TB patients to assess POC test accuracy, safety and acceptability in settings in which immediate access to DM services may be difficult. METHODS: We measured POC and accredited laboratory HbA1c (using high-performance liquid chromatography) in 1942 TB patients aged 18 years recruited from Peru, Romania, Indonesia and South Africa. We calculated overall agreement and individual variation (mean ± 2 standard deviations) stratified by country, age, sex, body mass index (BMI), HbA1c level and comorbidities (anaemia, human immunodeficiency virus [HIV]). We used an error grid approach to identify disagreement that could raise significant concerns. RESULTS: Overall mean POC HbA1c values were modestly higher than laboratory HbA1c levels by 0.1% units (95%CI 0.1-0.2); however, there was a substantial discrepancy for those with severe anaemia (1.1% HbA1c, 95%CI 0.7-1.5). For 89.6% of 1942 patients, both values indicated the same DM status (no DM, HbA1c <6.5%) or had acceptable deviation (relative difference <6%). Individual agreement was variable, with POC values up to 1.8% units higher or 1.6% lower. For a minority, use of POC HbA1c alone could result in error leading to potential overtreatment (n = 40, 2.1%) or undertreatment (n = 1, 0.1%). The remainder had moderate disagreement, which was less likely to influence clinical decisions. CONCLUSION: POC HbA1c is pragmatic and sufficiently accurate to screen for hyperglycaemia and DM risk among TB patients.

Distance dependent centroid to centroid force fields using high resolution decoys.

Simplified force fields play an important role in protein structure prediction and de novo protein design by requiring less computational effort than detailed atomistic potentials. A side chain centroid based, distance dependent pairwise interaction potential has been developed. A linear programming based formulation was used in which non-native "decoy" conformers are forced to take a higher energy compared with the corresponding native structure. This model was trained on an enhanced and diverse protein set. High quality decoy structures were generated for approximately 1400 nonhomologous proteins using torsion angle dynamics along with restricted variations of the hydrophobic cores of the native structure. The resulting decoy set was used to train the model yielding two different side chain centroid based force fields that differ in the way distance dependence has been used to calculate energy parameters. These force fields were tested on an independent set of 148 test proteins with 500 decoy structures for each protein. The side chain centroid force fields were successful in correctly identifying approximately 86% native structures. The Z-scores produced by the proposed centroid-centroid distance dependent force fields improved compared with other distance dependent C(alpha)-C(alpha) or side chain based force fields.

Endothelial cell- and lymphocyte-based in vitro systems for understanding KSHV biology.

Kaposi sarcoma (KS), the most common AIDS-associated malignancy, is a multifocal tumor characterized by deregulated angiogenesis, proliferation of spindle cells, and extravasation of inflammatory cells and erythrocytes. Kaposi sarcoma-associated herpesvirus (KSHV; also human herpesvirus-8) is implicated in all clinical forms of KS. Endothelial cells (EC) harbor the KSHV genome in vivo, are permissive for virus infection in vitro, and are thought to be the precursors of KS spindle cells. Spindle cells are rare in early patch-stage KS lesions but become the predominant cell type in later plaque- and nodular-stage lesions. Alterations in endothelial/spindle cell physiology that promote proliferation and survival are thus thought to be important in disease progression and may represent potential therapeutic targets. KSHV encodes genes that stimulate cellular proliferation and migration, prevent apoptosis, and counter the host immune response. The combined effect of these genes is thought to drive the proliferation and survival of infected spindle cells and influence the lesional microenvironment. Large-scale gene expression analyses have revealed that KSHV infection also induces dramatic reprogramming of the EC transcriptome. These changes in cellular gene expression likely contribute to the development of the KS lesion. In addition to KS, KSHV is also present in B cell neoplasias including primary effusion lymphoma and multicentric Castleman disease. A combination of virus and virus-induced host factors are similarly thought to contribute to establishment and progression of these malignancies. A number of lymphocyte- and EC-based systems have been developed that afford some insight into the means by which KSHV contributes to malignant transformation of host cells. Whereas KSHV is well maintained in PEL cells cultured in vitro, explanted spindle cells rapidly lose the viral episome. Thus, endothelial cell-based systems for studying KSHV gene expression and function, as well as the effect of infection on host cell physiology, have required in vitro infection of primary or life-extended EC. This chapter includes a review of these in vitro cell culture systems, acknowledging their strengths and weaknesses and putting into perspective how each has contributed to our understanding of the complex KS lesional environment. In addition, we present a model of KS lesion progression based on findings culled from these models as well as recent clinical advances in KS chemotherapy. Thus this unifying model describes our current understanding of KS pathogenesis by drawing together multiple theories of KS progression that by themselves cannot account for the complexities of tumor development.

Unlinked anonymous HIV prevalence among New Zealand sexual health clinic attenders: 2005-2006.

This unlinked anonymous study aimed at determining the prevalence of HIV among sexual health clinic attenders having blood samples taken for syphilis and/or hepatitis B serology in six major New Zealand cities over a 12-month period in 2005-2006. Overall, seroprevalence was five per 1000 (47/9439). Among men who have sex with men (MSM), the overall prevalence and that of previously undiagnosed HIV were 44.1 and 20.1 per 1000, respectively. In heterosexual men, the overall prevalence was 1.2 per 1000 and in women 1.4 per 1000. HIV remains to be concentrated among homosexual and bisexual men. Comparison with a previous survey in 1996-1997 suggests an increase in the prevalence of undiagnosed HIV among MSM and also an increase in the number of MSM attending sexual health clinics. The low prevalence of HIV among heterosexuals suggests no extensive spread into the groups identified at risk of other sexually transmitted infections.

Good outcome in HIV-infected refugees after resettlement in New Zealand: population study.

BACKGROUND: The aims of this study were to determine the clinical characteristics on arrival and the subsequent clinical outcome of HIV-infected UN quota refugees who settled in New Zealand during the last 11 years and to estimate their rate of HIV transmission. METHODS: A population study was conducted. Data were provided by the Mangere Refugee Resettlement Centre, the infectious disease physicians caring for the subjects, the New Zealand AIDS Epidemiology Group and laboratories carrying out HIV viral load assays. RESULTS: One hundred of 7732 (1.3%) UN quota refugees were HIV positive; mean age 30 years, 56% were men, median initial CD4 count was 320 (range 20-1358). HIV infection was most commonly acquired by heterosexual intercourse (74%). The median follow up was 5.0 years (range 1 month to 9.7 years). Five died and 15 subjects had 16 AIDS-defining illnesses, most commonly tuberculosis (n = 10). Sixty subjects commenced highly active antiretroviral therapy of whom 36/59 (61%) had an undetectable HIV viral load after 1 year of treatment. None of the six children born to HIV-infected women in New Zealand were infected. There were two known cases of horizontal transmission of HIV infection. CONCLUSION: Although HIV-infected quota refugees often have to overcome severe social, cultural and financial handicaps, their clinical outcome is generally very good, with response rates to highly active antiretroviral therapy that are similar to other patient groups. Furthermore, they have not been a significant source of transmission of HIV infection after resettlement in New Zealand.

The therapeutic role of mental health nurses in psychiatric intensive care: A mixed-methods investigation in an inner-city mental health service.

WHAT IS KNOWN ON THE SUBJECT?: Mental health services have been radically transformed since the 1990s, with an emphasis on care in the community. However, acute psychiatric wards remain an important component of service provision. Research shows that patients receive limited therapeutic interaction with nurses in such settings. A recent review showed that just 4%-12% of nurses' time was spent on activities that could be considered therapeutic. WHAT THIS STUDY ADDS TO EXISTING KNOWLEDGE?: Whereas nurses wanted more time for individual therapeutic activity, patients were content with brief interactions. However, such contact was not always available, partly due to workload pressures. Both nurses and patients believed that a collaborative approach, involving the whole multidisciplinary team, was key to the success of therapeutic engagement. The meaning of therapeutic engagement remains nebulous. WHAT ARE THE IMPLICATIONS FOR PRACTICE?: Nurse education, ward management and clinical supervision should have greater emphasis on therapeutic engagement. Further research is needed to develop therapeutic engagement in acute psychiatric settings; such work should involve patients as active and equal partners. ABSTRACT: Introduction Despite indications that therapeutic interaction is beneficial for patients and for nurses' job satisfaction in acute psychiatric care, research shows a small amount of nurses' time is spent on such activity. Aims This study investigated the actual and potential therapeutic role of the mental health nurse in psychiatric intensive care, where admission is due to violence or aggression. Methods In a mixed-methods concurrent triangulation design, clinician and patient activity was observed using a structured measurement tool, and qualitative interviews were conducted with four practitioners and six patients. Findings were generated using thematic analysis and descriptive statistics. Results Of the directly observed 234 clinician and 309 patient activities, 20.9% and 15.9%, respectively, were classified as therapeutic engagement. Interviews revealed that both clinicians and patients wanted more therapeutic contact, but whereas nurses wanted longer time to spend in individual sessions, patients preferred brief but more frequent interaction with nurses. Discussion This study shows disparity between actual and desirable levels of therapeutic interaction. Apart from organizational constraints, a fundamental problem is the lack of definition or established practices of therapeutic engagement. Implications for Practice There should be more emphasis on therapeutic engagement in nurse education, ward management and clinical supervision.

Feasibility of two active case finding approaches for detection of tuberculosis in Bandung City, Indonesia.

Setting: A community health clinic catchment area in the eastern part of Bandung City, Indonesia. Objective: To evaluate the feasibility of two different screening interventions using community health workers (CHWs) in detecting tuberculosis (TB) cases. Design: This was a feasibility study of 1) house-to-house TB symptom screening of five randomly selected 'neighbourhoods' in the catchment area, and 2) selected screening of household contacts of TB index patients and their neighbouring households. Acceptability was assessed through focus group discussions with key stakeholders. Results: Of 5100 individuals screened in randomly selected neighbourhoods, 48 (0.9%) reported symptoms, of whom 38 provided sputum samples; no positive TB was found. No TB cases were found among the 88 household contacts or the 423 neighbourhood contacts. With training, regular support and supervision from research staff and local community health centre staff, CHWs were able to undertake screening effectively, and almost all householders were willing to participate. Conclusion: The use of CHWs for TB screening could be integrated into routine practice relatively easily in Indonesia. The effectiveness of this would need further exploration, particularly with the use of improved diagnostics such as chest X-ray and sputum culture.

Contexte : Une zone de desserte d'un centre de santé communautaire dans la partie est de la ville de Bandung, Indonésie.Objectif : Evaluer la faisabilité de deux différentes interventions de dépistage recourant à des travailleurs de santé communautaire (CHW) dans la détection des cas de la tuberculose (TB).Schéma : Une étude de faisabilité : 1) du dépistage des symptômes de TB en porte à porte dans cinq quartiers sélectionnés au hasard dans la zone de desserte, et 2) recherche des contacts familiaux des patients TB index et leur voisinage. L'acceptabilité a été évaluée grâce à des groupes focaux avec les partenaires clés.Résultats : Sur 5100 individus dépistés dans des quartiers sélectionnés au hasard, 48 (0,9%) ont rapporté des symptômes, dont 38 ont fourni des crachats : aucune TB n'a été découverte. Aucun cas de TB n'a été trouvé parmi les 88 contacts familiaux ni parmi les 423 personnes du voisinage. Avec une formation, un soutien régulier et une supervision par le personnel de recherche et le personnel du centre de santé communautaire local, les CHW pourraient efficacement entreprendre le dépistage, et presque tous les habitants ont accepté de participer.Conclusion : Le recours aux CHW pour le dépistage de la TB pourrait assez facilement être intégré dans la pratique de routine en Indonésie. L'efficacité de cette stratégie mériterait d'être explorée davantage, en particulier en recourant à des outils diagnostiques améliorés comme une radiographie pulmonaire et une culture de crachats.

Marco de referencia: La zona de influencia de un consultorio comunitario en la parte oriental de la ciudad de Bandung, en Indonesia.Objetivo: Evaluar la factibilidad de dos intervenciones diferentes de detección sistemática practicadas por los agentes de salud comunitarios (CHW) en la búsqueda de casos de tuberculosis (TB).Método: Se llevó a cabo un estudio de factibilidad que examinó: 1) la detección sistemática de los síntomas de TB, de puerta a puerta, en cinco barrios de la zona de influencia escogidos de manera aleatoria y 2) la investigación de contactos de los casos nuevos de TB en sus hogares y en el vecindario. Se organizaron grupos de opinión con interesados directos clave a fin de evaluar la factibilidad de la intervención.Resultados: De las 5100 personas participantes en los vecindarios escogidos, 48 refirieron síntomas (0,9%) y 38 aportaron muestras de esputo, de las cuales ninguna fue positiva para TB. No se detectaron casos de TB en los 88 hogares de los contactos ni en los 423 contactos del vecindario. Con la capacitación, el apoyo periódico y la supervisión por parte del grupo de investigación y del personal de salud del centro comunitario local, los CHW emprendieron de manera eficaz una detección sistemática y casi todos los miembros de los hogares aceptaron participar.Conclusión: La participación de los CHW en la detección sistemática de la TB se puede integrar sin dificultad en la práctica corriente en Indonesia. Se precisa un examen más detenido de la eficacia práctica de esta medida, en especial con la utilización de métodos diagnósticos mejorados como la radiografía de tórax y el cultivo de muestras de esputo.
