Disclosure of HIV status to sexual partners amongst people who receive antiretroviral treatment in Kampala, Uganda

Magister Public Health - MPHThe increased number of new infections in Uganda necessitates HIV prevention programmes that address risky behaviours especially among heterosexual populations. The AIDS Support Organisation (TASO) is the largest indigenous HIV/AIDS agency serving Uganda and the Great Lakes Region. TASO endeavours to empower sexually active clients to disclose their sero-status to their sexual partners and promotes partner testing for HIV. In spite of these efforts, only 12% of 2,071 sexually active clients in Mulago centre had disclosed by the end of 2006. This study aimed to explore the factors that influence clients’ decisions to disclose their HIV status to their partners in TASO Mulago, Kampala, Uganda. The study used a qualitative approach. Fourteen (14) in-depth interviews were conducted with English and Luganda speaking adult male and female clients on antiretroviral treatment (ART), in TASO Mulago. A focus group discussion (FGD) was conducted with 8 purposively selected ART clients who were considered to be ‘expert’ clients in TASO Mulago. These participants were expert clients/ peer educators, who were open about their HIV status and have been involved in HIV/AIDS education and advocacy. The individual interviews and the focus group discussion were transcribed verbatim, and subjected to thematic and content analysis. Male and female participants who were married (primary relationship) disclosed their sero-status to their sexual partners, while few of those cohabiting or in steady relationship (only one) disclosed to their partners. Enabling factors to disclose to current sexual partners included: desire for partner to get treatment, need for the partner’s support, having prior knowledge of partner’s HIV status, out of anger, and having anxiety about the future. Some of the barriers to disclosure included: fear of blame and disappointing the partner, fear of abandonment, fear of stigma and discrimination Participants suggested that couple counselling and testing, economic independence, peer support and involvement of the TASO staff in disclosure should be considered to facilitate or promote disclosure to sexual partners.While strategies like HBHCT and couple counselling have enhanced disclosure among sexual partners on ART living together in stable married relationships (primary), the partners in secondary relationships (cohabiting and steady) especially women, continue to face challenges in disclosure yet their sexual partners are at risk of HIV infection. The study has re-affirmed the fact that while some people living with HIV/AIDS wish to disclose their HIV status to their partners, there are compound factors that make it difficult to disclose. This calls for effective strategies by government, TASO and other agencies to ensure that sexual partners especially in cohabiting and steady relationships are disclosed to in order to reduce their vulnerability to HIV infection

A pilot study of the association of rs6127099 polymorphism with primary hyperparathyroidism

Primary hyperparathyroidism (PHPT) is the third most common endocrine disorder characterized by autonomous parathyroid hormone (PTH) secretion by one or more parathyroid glands and increased serum calcium concentration. A recent genome wide association study showed that the rs6127099 polymorphism, which is located upstream the CYP24A1 (Cytochrome P450, family 24, subfamily A, polypeptide 1) gene, is associated strongly with elevated serum PTH levels. CYP24A1 gene encodes an enzyme of cytochrome P450, which is responsible for inactivating vitamin D metabolites. As PTH hypersecretion is a common clinical sign of PHPT, the aim of the present study was to investigate the role of the polymorphism rs6127099 as a genetic predisposing factor for PHPT manifestation. Thirty-nine unrelated patients with sporadic PHPT and an equal number of healthy volunteers were enrolled in the study.Polymerase chain reaction and restriction fragment length polymorphism assays were used for rs6127099 genotyping in both groups. No statistically significant difference was observed comparing CYP24A1 rs6127099 A>T genotypes (p = 0.836) and A vs T allele (p = 0.383) distribution between PHPT patients and controls. In conclusion, rs6127099 polymorphism seems not to be associated with PHPT predisposition. Further independent studies, as the present one, are necessary to evaluate the strong association of rs6127099 polymorphism with PTH levels and its prognostic role in PHPT predisposition

Systematic review of the methods of health economic models assessing antipsychotic medication for schizophrenia

Background Numerous economic models have assessed the cost-effectiveness of antipsychotic medications in schizophrenia. It is important to understand what key impacts of antipsychotic medications were considered in the existing models and limitations of existing models in order to inform the development of future models. Objectives This systematic review aims to identify which clinical benefits, clinical harms, costs and cost savings of antipsychotic medication have been considered by existing models, to assess quality of existing models and to suggest good practice recommendations for future economic models of antipsychotic medications. Methods An electronic search was performed on multiple databases (MEDLINE, EMBASE, PsycInfo, Cochrane database of systematic reviews, The NHS Economic Evaluation Database and Health Technology Assessment database) to identify economic models of schizophrenia published between 2005–2020. Two independent reviewers selected studies for inclusion. Study quality was assessed using the National Institute for Health and Care Excellence (NICE) checklist and the Cooper hierarchy. Key impacts of antipsychotic medications considered by exiting models were descriptively summarised. Results Sixty models were included. Existing models varied greatly in key impacts of antipsychotic medication included in the model, especially in clinical outcomes used for assessing reduction in psychotic symptoms and types of adverse events considered in the model. Quality of existing models was generally low due to failure to capture the health and cost impact of adverse events of antipsychotic medications and input data not obtained from best available source. Good practices for modelling antipsychotic medications are suggested. Discussions This review highlights inconsistency in key impacts considered by different models, and limitations of the existing models. Recommendations on future research are provided

The UPBEAT nurse-delivered personalized care intervention for people with coronary heart disease who report current chest pain and depression: a randomised controlled pilot study

Background: Depression is common in people with coronary heart disease (CHD) and associated with worse outcome. This study explored the acceptability and feasibility of procedures for a trial and for an intervention, including its potential costs, to inform a definitive randomized controlled trial (RCT) of a nurse-led personalised care intervention for primary care CHD patients with current chest pain and probable depression. Methods: Multi-centre, outcome assessor-blinded, randomized parallel group study. CHD patients reporting chest pain and scoring 8 or more on the HADS were randomized to personalized care (PC) or treatment as usual (TAU) for 6 months and followed for 1 year. Primary outcome was acceptability and feasibility of procedures; secondary outcomes included mood, chest pain, functional status, well being and psychological process variables. Result: 1001 people from 17 General Practice CHD registers in South London consented to be contacted; out of 126 who were potentially eligible, 81 (35% female, mean age = 65 SD11 years) were randomized. PC participants (n = 41) identified wide ranging problems to work on with nurse-case managers. Good acceptability and feasibility was indicated by low attrition (9%), high engagement and minimal nurse time used (mean/SD = 78/19 mins assessment, 125/91 mins telephone follow up). Both groups improved on all outcomes. The largest between group difference was in the proportion no longer reporting chest pain (PC 37% vs TAU 18%; mixed effects model OR 2.21 95% CI 0.69, 7.03). Some evidence was seen that self efficacy (mean scale increase of 2.5 vs 0.9) and illness perceptions (mean scale increase of 7.8 vs 2.5) had improved in PC vs TAU participants at 1 year. PC appeared to be more cost effective up to a QALY threshold of approximately £3,000. Conclusions: Trial and intervention procedures appeared to be feasible and acceptable. PC allowed patients to work on unaddressed problems and appears cheaper than TAU

Influenza surveillance among children with pneumonia admitted to a district hospital in coastal Kenya, 2007-2010

Background: Influenza data gaps in sub-Saharan Africa include incidence, case fatality, seasonal patterns, and associations with prevalent disorders. Methods: Nasopharyngeal samples from children aged <12 years who were admitted to Kilifi District Hospital during 2007–2010 with severe or very severe pneumonia and resided in the local demographic surveillance system were screened for influenza A, B, and C viruses by molecular methods. Outpatient children provided comparative data. Results: Of 2002 admissions, influenza A virus infection was diagnosed in 3.5% (71), influenza B virus infection, in 0.9% (19); and influenza C virus infection, in 0.8% (11 of 1404 tested). Four patients with influenza died. Among outpatients, 13 of 331 (3.9%) with acute respiratory infection and 1 of 196 without acute respiratory infection were influenza positive. The annual incidence of severe or very severe pneumonia, of influenza (any type), and of influenza A, was 1321, 60, and 43 cases per 100 000 <5 years of age, respectively. Peak occurrence was in quarters 3–4 each year, and approximately 50% of cases involved infants: temporal association with bacteremia was absent. Hypoxia was more frequent among pneumonia cases involving influenza (odds ratio, 1.78; 95% confidence interval, 1.04–1.96). Influenza A virus subtypes were seasonal H3N2 (57%), seasonal H1N1 (12%), and 2009 pandemic H1N1 (7%). Conclusions: The burden of influenza was small during 2007–2010 in this pediatric hospital in Kenya. Influenza A virus subtype H3N2 predominated, and 2009 pandemic influenza A virus subtype H1N1 had little impact

Serotype Diversity of Respiratory Human Adenoviruses amongst Pediatric Patients from Western Kenya, 2010-2012

Background: Respiratory illnesses are common among pediatric patients in Kenya, and many are attributed to viral causes. However, there is limited knowledge of the diversity of viral etiologies associated with these illnesses. Objective: To characterize respiratory adenoviruses isolates using serological and molecular approaches. Methods: A total of 1,879 samples were collected from symptomatic pediatric patients seeking medical care at New Nyanza Provincial General Hospital during the period of June 2010 to June 2012 and screened for adenoviruses as well as other respiratory viruses. Sixteen respiratory human adenoviruses (HAdVs) were isolated in Hep2 cell culture and characterized them using Immunofluorescence Assay, viral DNA amplification, sequencing and phylogenomics. Results: Phylogenetic characterization of the HAdVs using the hyper variable region 7 of the hexon gene identified HAdV B and C as the major species associated with respiratory infections during the study period. Amongst these, a single B-type and four C-type serotypes were identified.  The serotype distribution consisted of 31% HAdV B7, 25% HAdV C1, 25% HAdV C2, 6% HAdV C5, and 13% HAdV C6. Positive selection was observed in the nucleotide sequences from HAdV B7 and HAdV C5 signaling evolution of these two serotypes. Conclusion: These finding may be useful to policy makers regarding appropriate strain selection for vaccination in Kenya. Keywords: Respiratory Human adenovirus, Kenya, Pediatric, Serotype, Hexon, HVR-

Seclusion and Psychiatric Intensive Care Evaluation Study (SPICES) : Combined qualitative and quantitative approaches to the uses and outcomes of coercive practices in mental health services

BackgroundSeclusion (the isolation of a patient in a locked room) and transfer to a psychiatric intensive care unit (PICU; a specialised higher-security ward with higher staffing levels) are two common methods for the management of disturbed patient behaviour within acute psychiatric hospitals. Some hospitals do not have seclusion rooms or easy access to an on-site PICU. It is not known how these differences affect patient management and outcomes.ObjectivesTo (1) assess the factors associated with the use of seclusion and PICU care, (2) estimate the consequences of the use of these on subsequent violence and costs (study 1) and (3) describe differences in the management of disturbed patient behaviour related to differential availability (study 2).DesignThe electronic patient record system at one trust was used to compare outcomes for patients who were and were not subject to seclusion or a PICU, controlling for variables, including recent behaviours. A cost-effectiveness analysis was performed (study 1). Nursing staff at eight hospitals with differing access to seclusion and a PICU completed attitudinal measures, a video test on restraint-use timing and an interview about the escalation pathway for the management of disturbed behaviour at their hospital. Analyses examined how results differed by access to PICU and seclusion (study 2).ParticipantsPatients on acute wards or PICUs in one NHS trust during the period 2008–13 (study 1) and nursing staff at eight randomly selected hospitals in England, with varying access to seclusion and to a PICU (study 2).Main outcome measuresAggression, violence and cost (study 1), and utilisation, speed of use and attitudes to the full range of containment methods (study 2).ResultsPatients subject to seclusion or held in a PICU were more likely than those who were not to be aggressive afterwards, and costs of care were higher, but this was probably because of selection bias. We could not derive satisfactory estimates of the causal effect of either intervention, but it appeared that it would be feasible to do so for seclusion based on an enriched sample of untreated controls (study 1). Hospitals without seclusion rooms used more rapid tranquillisation, nursing of the patient in a side room accompanied by staff and seclusion using an ordinary room (study 2). Staff at hospitals without seclusion rated it as less acceptable and were slower to initiate manual restraint. Hospitals without an on-site PICU used more seclusion, de-escalation and within-eyesight observation.LimitationsOfficial record systems may be subject to recording biases and crucial variables may not be recorded (study 1). Interviews were complex, difficult, constrained by the need for standardisation and collected in small numbers at each hospital (study 2).ConclusionsClosing seclusion rooms and/or restricting PICU access does not appear to reduce the overall levels of containment, as substitution of other methods occurs. Services considering expanding access to seclusion or to a PICU should do so with caution. More evaluative research using stronger designs is required.FundingThe National Institute for Health Research Health Services and Delivery Research programme

Factors associated with use of psychiatric intensive care and seclusion in adult inpatient mental health services

Aims.Within acute psychiatric inpatient services, patients exhibiting severely disturbed behaviour can be transferred to a psychiatric intensive care unit (PICU) and/or secluded in order to manage the risks posed to the patient and others. However, whether specific patient groups are more likely to be subjected to these coercive measures is unclear. Using robust methodological and statistical techniques, we aimed to determine the demographic, clinical and behavioural predictors of both PICU and seclusion.Methods.Data were extracted from an anonymised database comprising the electronic medical records of patients within a large South London mental health trust. Two cohorts were derived, (1) a PICU cohort comprising all patients transferred from general adult acute wards to a non-forensic PICU ward between April 2008 and April 2013 (N = 986) and a randomly selected group of patients admitted to general adult wards within this period who were not transferred to PICU (N = 994), and (2) a seclusion cohort comprising all seclusion episodes occurring in non-forensic PICU wards within the study period (N = 990) and a randomly selected group of patients treated in these wards who were not secluded (N = 1032). Demographic and clinical factors (age, sex, ethnicity, diagnosis, admission status and time since admission) and behavioural precursors (potentially relevant behaviours occurring in the 3 days preceding PICU transfer/seclusion or random sample date) were extracted from electronic medical records. Mixed effects, multivariable logistic regression analyses were performed with all variables included as predictors.Results.PICU cases were significantly more likely to be younger in age, have a diagnosis of bipolar disorder and to be held on a formal section compared with patients who were not transferred to PICU; female sex and longer time since admission were associated with lower odds of transfer. With regard to behavioural precursors, the strongest predictors of PICU transfer were incidents of physical aggression towards others or objects and absconding or attempts to abscond. Secluded patients were also more likely to be younger and legally detained relative to non-secluded patients; however, female sex increased the odds of seclusion. Likelihood of seclusion also decreased with time since admission. Seclusion was significantly associated with a range of behavioural precursors with the strongest associations observed for incidents involving restraint or shouting.Conclusions.Whilst recent behaviour is an important determinant, patient age, sex, admission status and time since admission also contribute to risk of PICU transfer and seclusion. Alternative, less coercive strategies must meet the needs of patients with these characteristics

A systematic review of economic models across the entire schizophrenia pathway

Background Schizophrenia is associated with a high economic burden. Economic models can help to inform resource allocation decisions to maximise benefits to patients. Objectives This systematic review aims to assess the availability, quality and consistency of conclusions of health economic models evaluating the cost effectiveness of interventions for schizophrenia. Methods An electronic search was performed on multiple databases (MEDLINE, EMBASE, PsycINFO, Cochrane database of systematic reviews, NHS Economic Evaluation Database and Health Technology Assessment database) to identify economic models of interventions for schizophrenia published between 2005 and 2020. Two independent reviewers selected studies for inclusion. Study quality was assessed using the National Institute for Health and Care Excellence (NICE) checklist and the Cooper hierarchy. Model characteristics and conclusions were descriptively summarised. Results Seventy-three models met inclusion criteria. Seventy-eight percent of existing models assessed antipsychotics; however, due to inconsistent conclusions reported by different studies, no antipsychotic can be considered clearly cost effective compared with the others. A very limited number of models suggest that the following non-pharmacological interventions might be cost effective: psychosocial interventions, stratified tests, employment intervention and intensive intervention to improve liaison between primary and secondary care. The quality of included models is generally low due to use of a short time horizon, omission of adverse events of interventions, poor data quality and potential conflicts of interest. Conclusions This review highlights a lack of models for non-pharmacological interventions, and limitations of the existing models, including low quality and inconsistency in conclusions. Recommendations on future modelling approaches for schizophrenia are provided

UPBEAT-UK::a programme of research into the relationship between coronary heart disease and depression in primary care patients

Many people with coronary heart disease (CHD) are depressed and research on people who have had a heart attack found that depression increases the chance of further heart attacks. The UPBEAT-UK team conducted research with people on general practitioner CHD registers in 33 south London practices to: examine any link between CHD, depression and worse future heart disease; and develop case\ud management by practice nurses for people with CHD and depression. We followed 803 people with CHD for up to 3 years, assessing them for depression, chest pain and\ud worsening of heart disease, and also measured care costs. We asked patients, GPs and nurses how people with CHD and depression should be treated. From this, we developed care designed for each person called ‘personalised care’ (PC). We tested it in 41 people (while 40 people received their usual care from GPs)\ud with chest pain and depression, to assess how acceptable it is, whether or not it helps and what the costs would be. PC was acceptable to people, and those who received it reported less chest pain 6 and 12 months later. Costs were lower following PC but the difference was not statistically significant. Just under half of those with CHD had chest pain. Depression was frequent, but anxiety was more\ud common and increased the chances of both heart attacks and death. We conclude that further research is needed to understand the links between anxiety, chest pain and heart\ud disease, and to further develop our promising findings that PC can be helpful in reducing chest pain in\ud general practice
