RESUMEN

OBJECTIVES: Acceptance and commitment therapy (ACT) is a relatively new type of psychotherapy effective for treating depression and anxiety amongst family care partners of persons living with dementia [PLWD]. However, care partner engagement in mental health services is low and specific guidelines for designing ACT programs for care partners of PLWD do not exist. The purpose of this scoping review was to examine patterns in care partner engagement in ACT programs to identify program factors potentially influencing engagement. METHODS: A comprehensive scoping review according to Arksey and O'Malley's framework was followed. Databases and grey literature were searched for primary studies of ACT programs with care partners of PLWD. Data were charted and synthesized. RESULTS: Ten studies met inclusion criteria and were analyzed. Amongst these, engagement was highest in three ACT programs that were delivered individually, remotely and were therapist-led or supported. Conversely, engagement was the lowest in two ACT programs that were self-directed, web-based and had minimal or no care partner-therapist interaction. Program factors perceived as influencing engagement included tailoring and personalization, mode of delivery and format, therapeutic support and connectedness, program duration and pace. CONCLUSION: Findings from this review suggest that care partners engagement may be promoted by designing ACT programs that focus on the therapeutic client-therapist relationship, are delivered remotely and individually. Future research should focus on evaluation of best implementation practices for engagement and effectiveness.

RESUMEN

Bis(thiosemicarbazone) and pyridylhydrazone-thiosemicarbazone chelators have demonstrated utility in nuclear medicine. In particular, the 64Cu2+ complexes have been extensively developed for hypoxia imaging and molecular imaging of peptide and protein markers of disease. However, the chemistry and application of bis(thiosemicarbazone) and pyridylhydrazone-thiosemicarbazone chelators in combination with 99mTc, the most widely used radionuclide in nuclear medicine, is underexplored. Herein, a series of bis(thiosemicarbazone) and pyridylhydrazone-thiosemicarbazone chelators were radiolabeled with nitrido-technetium-99m in an optimized one-pot synthesis from [99mTc]TcO4-. Optimization of the radiochemical syntheses allowed for production of the complexes in >90% radiochemical conversion with apparent molar activities of 3.3-5 GBq/µmol. Competition experiments demonstrated the excellent stability of the complexes. The nitrido-technetium-99 complexes were synthesized, and the chemical identities were investigated using mass spectrometry, spectroscopy, and density functional theory calculations. Complexation of nitrido-rhenium(V) was achieved with the N4-dialkylated bis(thiosemicarbazones). Planar imaging and ex vivo biodistribution studies of the five 99mTc complexes were conducted on healthy BALB/c mice to determine in vivo behavior. The lipophilic nature of the complexes resulted in uptake of 1.6-5.7% ID g-1 in the brain at 2 min postinjection and retention of 0.4-1.7% ID g-1 at 15 min postinjection. The stability of the complexes and the biodistribution data demonstrate that these chelators are ideal platforms for future production of radiopharmaceutical candidates.

RESUMEN

Psychotherapy supervision is an essential component of graduate medical education in psychiatry. However, most psychotherapy supervisors have never had training specific to supervision, and the requisite skills have received little attention in the literature. The authors of this article describe the first year of a pilot project that was aimed at fostering interest and skill in psychotherapy supervision among senior residents. In this model, a postgraduate year (PGY)-4 resident supervised a PGY-2 resident's psychodynamic psychotherapy while receiving supervisory support from a senior faculty member. Feedback from the two residents and the residency program director was positive. The PGY-2 resident reported benefiting from near-peer supervision. The PGY-4 resident continued to supervise residents after graduation and felt well prepared to assume that role. The residency program continued to use this model after the pilot period. Other training programs can replicate this model to nurture the next generation of psychotherapy supervisors.

RESUMEN

BACKGROUND: The specificity of nucleic acid amplification tests (NAATs) used for early infant diagnosis (EID) of HIV infection is <100%, leading some HIV-uninfected infants to be incorrectly identified as HIV-infected. The World Health Organization recommends that infants undergo a second NAAT to confirm any positive test result, but implementation is limited. Our objective was to determine the impact and cost-effectiveness of confirmatory HIV testing for EID programmes in South Africa. METHOD AND FINDINGS: Using the Cost-effectiveness of Preventing AIDS Complications (CEPAC)-Pediatric model, we simulated EID testing at age 6 weeks for HIV-exposed infants without and with confirmatory testing. We assumed a NAAT cost of US$25, NAAT specificity of 99.6%, NAAT sensitivity of 100% for infants infected in pregnancy or at least 4 weeks prior to testing, and a mother-to-child transmission (MTCT) rate at 12 months of 4.9%; we simulated guideline-concordant rates of testing uptake, result return, and antiretroviral therapy (ART) initiation (100%). After diagnosis, infants were linked to and retained in care for 10 years (false-positive) or lifelong (true-positive). All parameters were varied widely in sensitivity analyses. Outcomes included number of infants with false-positive diagnoses linked to ART per 1,000 ART initiations, life expectancy (LE, in years) and per-person lifetime HIV-related healthcare costs. Both without and with confirmatory testing, LE was 26.2 years for HIV-infected infants and 61.4 years for all HIV-exposed infants; clinical outcomes for truly infected infants did not differ by strategy. Without confirmatory testing, 128/1,000 ART initiations were false-positive diagnoses; with confirmatory testing, 1/1,000 ART initiations were false-positive diagnoses. Because confirmatory testing averted costly HIV care and ART in truly HIV-uninfected infants, it was cost-saving: total cost US$1,790/infant tested, compared to US$1,830/infant tested without confirmatory testing. Confirmatory testing remained cost-saving unless NAAT cost exceeded US$400 or the HIV-uninfected status of infants incorrectly identified as infected was ascertained and ART stopped within 3 months of starting. Limitations include uncertainty in the data used in the model, which we examined with sensitivity and uncertainty analyses. We also excluded clinical harms to HIV-uninfected infants incorrectly treated with ART after false-positive diagnosis (e.g., medication toxicities); including these outcomes would further increase the value of confirmatory testing. CONCLUSIONS: Without confirmatory testing, in settings with MTCT rates similar to that of South Africa, more than 10% of infants who initiate ART may reflect false-positive diagnoses. Confirmatory testing prevents inappropriate HIV diagnosis, is cost-saving, and should be adopted in all EID programmes.

RESUMEN

BACKGROUND: Diagnosis of human immunodeficiency virus (HIV) infection during early infancy (commonly known as "early infant HIV diagnosis" [EID]) followed by prompt initiation of antiretroviral therapy dramatically reduces mortality. EID testing is recommended at 6 weeks of age, but many infant infections are missed. DESIGN/METHODS: We simulated 4 EID testing strategies for HIV-exposed infants in South Africa: no EID (diagnosis only after illness; hereafter, "no EID"), testing once (at birth alone or at 6 weeks of age alone; hereafter, "birth alone" and "6 weeks alone," respectively), and testing twice (at birth and 6 weeks of age; hereafter "birth and 6 weeks"). We calculated incremental cost-effectiveness ratios (ICERs), using discounted costs and life expectancies for all HIV-exposed (infected and uninfected) infants. RESULTS: In the base case (guideline-concordant care), the no EID strategy produced a life expectancy of 21.1 years (in the HIV-infected group) and 61.1 years (in the HIV-exposed group); lifetime cost averaged $1430/HIV-exposed infant. The birth and 6 weeks strategy maximized life expectancy (26.5 years in the HIV-infected group and 61.4 years in the HIV-exposed group), costing $1840/infant tested. The ICER of the 6 weeks alone strategy versus the no EID strategy was $1250/year of life saved (19% of South Africa's per capita gross domestic product); the ICER for the birth and 6 weeks strategy versus the 6 weeks alone strategy was $2900/year of life saved (45% of South Africa's per capita gross domestic product). Increasing the proportion of caregivers who receive test results and the linkage of HIV-positive infants to antiretroviral therapy with the 6 weeks alone strategy improved survival more than adding a second test. CONCLUSIONS: EID at birth and 6 weeks improves outcomes and is cost-effective, compared with EID at 6 weeks alone. If scale-up costs are comparable, programs should add birth testing after strengthening 6-week testing programs.

RESUMEN

BACKGROUND: Optimal laboratory monitoring of antiretroviral therapy (ART) for human immunodeficiency virus (HIV) remains controversial. We evaluated current and novel monitoring strategies in Côte d'Ivoire, West Africa. METHODS: We used the Cost-Effectiveness of Preventing AIDS Complications -International model to compare clinical outcomes, cost-effectiveness, and budget impact of 11 ART monitoring strategies varying by type (CD4 and/or viral load [VL]) and frequency. We included "adaptive" strategies (biannual then annual monitoring for patients on ART/suppressed). Mean CD4 count at ART initiation was 154/µL. Laboratory test costs were CD4=$11 and VL=$33. The standard of care (SOC; biannual CD4) was the comparator. We assessed cost-effectiveness relative to Côte d'Ivoire's 2013 per capita GDP ($1500). RESULTS: Discounted life expectancy was 16.69 years for SOC, 16.97 years with VL confirmation of immunologic failure, and 17.25 years for adaptive VL. Mean time on failed first-line ART was 3.7 years for SOC and <0.9 years for all routine/adaptive VL strategies. VL failure confirmation was cost-saving compared with SOC. Adaptive VL had an incremental cost-effectiveness ratio (ICER) of $4100/year of life saved compared with VL confirmation and increased the 5-year budget by $310/patient compared with SOC. Adaptive VL achieved an ICER <1× GDP if second-line ART and VL costs simultaneously decreased to $156 and $13, respectively. CONCLUSIONS: VL confirmation of immunologic failure is more effective and less costly than CD4 monitoring in Côte d'Ivoire. Adaptive VL monitoring reduces time on failing ART, is cost-effective, and should become standard in Côte d'Ivoire and similar settings.

RESUMEN

OBJECTIVE: The objective of this review is to map the infection prevention and control education and training that long-term care homes use with families during a pandemic or infectious outbreak. INTRODUCTION: During the COVID-19 pandemic, restrictions were imposed on visits to long-term care homes to decrease the risk of virus transmission. These restrictions had negative consequences for both residents and families. A scoping review of infection prevention and control education and training used with families will inform family visitation practices and policies during future infectious outbreaks. INCLUSION CRITERIA: This review will examine literature describing infection prevention and control education and training provided to families in long-term care homes. Research and narrative papers, including experimental; quasi-experimental; descriptive observational quantitative and qualitative studies; and reviews, text, policy, and opinion papers, will be considered for inclusion. METHODS: A 3-step approach will be followed, in line with the JBI methodology for scoping reviews. Published literature will be searched for in databases, including CINAHL, Embase, ERIC, MEDLINE, and AgeLine. Published and unpublished papers will be considered from 1990 to the present, in English or French. The World Health Organization, Centers for Disease Control, and the Public Health Agency of Canada websites will be searched for unpublished and gray literature. Two authors will independently review and assess studies for inclusion and extract the data. The findings will be charted in a narrative summary and tables.

RESUMEN

Objective: To characterize the socio-demographics and comorbid medical and psychiatric diagnoses of patients in the general hospital diagnosed with malingering. Method: We conducted a retrospective observational cohort study using data from the 2019 National Inpatient Sample, an all-payors database of acute care general hospital discharges in the United States, querying for patients aged 18 and older discharged with a diagnosis of "malingerer [conscious simulation]," ICD-10 code Z76.5. Results: 45,645 hospitalizations (95% CI: 43,503 to 47,787) during the study year included a discharge diagnosis of malingering. 56.1% were for male patients, and the median age was 43 years (IQR 33 to 54). Black patients represented 26.8% of the patients with a discharge diagnosis of malingering, compared to 14.9% of all patients sampled. Zip codes in the lowest household income quartile comprised 39.9% of malingering diagnoses. The top categories of primary discharge diagnoses of hospitalizations included medical ("Diabetes mellitus without complications"), psychiatric ("Depressive disorders"), and substance use ("Alcohol-related disorders") disorders. "Sepsis, unspecified organism," was the most common primary diagnosis. Conclusion: The striking overrepresentation of Black patients in hospitalizations with diagnosis of malingering raises concern about the roles of implicit and systemic biases in assigning this label. The disproportionate number of patients of low socioeconomic status is further suggestive of bias and disparity. Another potential contribution is that the lower health literacy in these populations results in a limited knowledge of traditional ways to meet one's needs and thus greater reliance on malingered behavior as an alternative means. Accurate description of these patients' socio-demographics and comorbid medical and psychiatric diagnoses with reliable data from large samples can lead to improved understanding of how the malingering label is applied and ultimately better patient care.

RESUMEN

OBJECTIVE: The Food and Drug Administration (FDA) warned about lamotrigine's arrhythmogenicity based on in vitro data. This systematic review investigates lamotrigine's effect on cardiac conduction and risk of sudden cardiac death (SCD) in individuals with and without cardiovascular disease. METHODS: We searched Web of Science and PubMed from inception through August 2021. We included studies measuring electrocardiogram (ECG) changes, laboratory abnormalities, or SCD among patients taking lamotrigine. Studies examining sudden unexpected death in epilepsy were excluded for scope. Two reviewers assessed articles and extracted data. We used the Effective Public Healthcare Panacea Project tool to evaluate confidence in evidence. RESULTS: Eight randomized controlled trials, 9 nonrandomized observational studies, and 24 case reports were identified, with >3054 total participants, >1606 of whom used lamotrigine. One randomized trial of older patients found an average QRS increase of 3.5 +/- 13.1 ms. Fifteen studies reported no changes in ECG parameters. Case reports documented QRS widening (13), Brugada syndrome (6), QTc prolongation (1) and SCD (2), though many ingested toxic quantities of lamotrigine and/or other medications. CONCLUSIONS: Evidence is insufficient to support the breadth of the FDA warning concerning lamotrigine's cardiac risk. Lamotrigine at therapeutic doses may be associated with modest, non-dangerous QRS widening.

RESUMEN

OBJECTIVE: This study aims to detail changes in presentations at a United States Emergency Department for suicidality before and after the outbreak of COVID-19. METHODS: A retrospective chart review was conducted of all adult patients who presented to an ED with suicidality and underwent psychiatric consultation during the study period. The cohorts consisted of patients who presented between December 2018 - May 2019 and December 2019 - May 2020. Information was collected on demographics, characteristics of suicidality, reasons for suicidality and disposition. The first wave from March - May 2020 was examined, using a difference-in-differences design to control for factors other than COVID-19 that may have influenced the outcomes' trend. RESULTS: Immediately following the pandemic outbreak there was a statistically significant increase in the proportion of undomiciled patients represented in visits for suicidality (40.7% vs. 57.4%; p-value <0.001). In addition, the proportion of patient visits attributed to social (18.0% vs. 29.2%; p-value 0.003) and structural (14.2% vs. 26.4%; p value <0.001) reasons for suicidality increased. Conversely, the proportion of visits due to psychiatric symptoms (70.5% vs 50.0%; p-value <0.001) decreased. Furthermore, patient visits were more likely to result in a medical admission (2.1% vs. 8.3%; p-value 0.002) and less likely to result in a psychiatric admission (68.4% vs 48.6%; p-value <0.001) during the initial phase of the pandemic. CONCLUSIONS: COVID-19 was associated with increased ED presentations for suicidality among undomiciled patients, as well as greater likelihood of social and structural reasons driving suicidality among all visits.

RESUMEN

INTRODUCTION: The Temprano and START trials provided evidence to support early ART initiation recommendations. We projected long-term clinical and economic outcomes of immediate ART initiation in Côte d'Ivoire. METHODS: We used a mathematical model to compare three potential ART initiation criteria: 1) CD4 <350/µL (ART<350/µL); 2) CD4 <500/µL (ART<500/µL); and 3) ART at presentation (Immediate ART). Outcomes from the model included life expectancy, 10-year medical resource use, incremental cost-effectiveness ratios (ICERs) in $/year of life saved (YLS), and 5-year budget impact. We simulated people with HIV (PWH) in care (mean CD4: 259/µL, SD 198/µL) and transmitted cases. Key input parameters to the analysis included first-line ART efficacy (80% suppression at 6 months) and ART cost ($90/person-year). We assessed cost-effectiveness relative to Côte d'Ivoire's 2017 per capita annual gross domestic product ($1,600). RESULTS: Immediate ART increased life expectancy by 0.34 years compared to ART<350/µL and 0.17 years compared to ART<500/µL. Immediate ART resulted in 4,500 fewer 10-year transmissions per 170,000 PWH compared to ART<350/µL. In cost-effectiveness analysis, Immediate ART had a 10-year ICER of $680/YLS compared to ART<350/µL, ranging from cost-saving to an ICER of $1,440/YLS as transmission rates varied. ART<500/µL was "dominated" (an inefficient use of resources), compared with Immediate ART. Immediate ART increased the 5-year HIV care budget from $801.9M to $812.6M compared to ART<350/µL. CONCLUSIONS: In Côte d'Ivoire, immediate compared to later ART initiation will increase life expectancy, decrease HIV transmission, and be cost-effective over the long-term, with modest budget impact. Immediate ART initiation is an appropriate, high-value standard of care in Côte d'Ivoire and similar settings.

RESUMEN

INTRODUCTION: In 2010, the WHO recommended women living with HIV breastfeed for 12 months while taking antiretroviral therapy (ART) to balance breastfeeding benefits against HIV transmission risks. To inform the 2016 WHO guidelines, we updated prior research on the impact of breastfeeding duration on HIV-free infant survival (HFS) by incorporating maternal ART duration, infant/child mortality and mother-to-child transmission data. METHODS: Using the Cost-Effectiveness of Preventing AIDS Complications (CEPAC)-Infant model, we simulated the impact of breastfeeding duration on 24-month HFS among HIV-exposed, uninfected infants. We defined "optimal" breastfeeding durations as those maximizing 24-month HFS. We varied maternal ART duration, mortality rates among breastfed infants/children, and relative risk of mortality associated with replacement feeding ("RRRF"), modelled as a multiplier on all-cause mortality for replacement-fed infants/children (range: 1 [no additional risk] to 6). The base-case simulated RRRF = 3, median infant mortality, and 24-month maternal ART duration. RESULTS: In the base-case, HFS ranged from 83.1% (no breastfeeding) to 90.2% (12-months breastfeeding). Optimal breastfeeding durations increased with higher RRRF values and longer maternal ART durations, but did not change substantially with variation in infant mortality rates. Optimal breastfeeding durations often exceeded the previous WHO recommendation of 12 months. CONCLUSIONS: In settings with high RRRF and long maternal ART durations, HFS is maximized when mothers breastfeed longer than the previously-recommended 12 months. In settings with low RRRF or short maternal ART durations, shorter breastfeeding durations optimize HFS. If mothers are supported to use ART for longer periods of time, it is possible to reduce transmission risks and gain the benefits of longer breastfeeding durations.

RESUMEN

INTRODUCTION: Men who have sex with men (MSM) and transgender women (TGW) in Brazil experience high rates of HIV infection. We examined the clinical and economic outcomes of implementing a pre-exposure prophylaxis (PrEP) programme in these populations. METHODS: We used the Cost-Effectiveness of Preventing AIDS Complications (CEPAC)-International model of HIV prevention and treatment to evaluate two strategies: the current standard of care (SOC) in Brazil, including universal ART access (No PrEP strategy); and the current SOC plus daily tenofovir/emtracitabine PrEP (PrEP strategy) until age 50. Mean age (31 years, SD 8.4 years), age-stratified annual HIV incidence (age ≤ 40 years: 4.3/100 PY; age > 40 years: 1.0/100 PY), PrEP effectiveness (43% HIV incidence reduction) and PrEP drug costs ($23/month) were from Brazil-based sources. The analysis focused on direct medical costs of HIV care. We measured the comparative value of PrEP in 2015 United States dollars (USD) per year of life saved (YLS). Willingness-to-pay threshold was based on Brazil's annual per capita gross domestic product (GDP; 2015: $8540 USD). RESULTS: Lifetime HIV infection risk among high-risk MSM and TGW was 50.5% with No PrEP and decreased to 40.1% with PrEP. PrEP increased per-person undiscounted (discounted) life expectancy from 36.8 (20.7) years to 41.0 (22.4) years and lifetime discounted HIV-related medical costs from $4100 to $8420, which led to an incremental cost-effectiveness ratio (ICER) of $2530/YLS. PrEP remained cost-effective (<1x GDP) under plausible variation in key parameters, including PrEP effectiveness and cost, initial cohort age and HIV testing frequency on/off PrEP. CONCLUSION: Daily tenofovir/emtracitabine PrEP among MSM and TGW at high risk of HIV infection in Brazil would increase life expectancy and be highly cost-effective.

RESUMEN

OBJECTIVES: Sexually transmitted and blood-borne infections (STBBIs) are associated with stigmatizing attitudes and beliefs, which can affect the quality of and access to health care, as well as mental health and quality of life. The current study describes the adaptation from an HIV-related stigma scale and pilot testing of a new STBBI Stigma Scale, assessing the stigmatizing attitudes and beliefs of health and social service providers in Canada. METHODS: 144 health and social service providers from across Canada completed the newly adapted scale assessing stigma associated with HIV, hepatitis C, other viral STBBIs and bacterial STBBIs, as well as demographic information, a scale of social desirability and measures of convergent and divergent validity. Participants were recruited through listservs and completed the scale online. RESULTS: The new scale, consisting of 21 items for each category, demonstrated excellent internal consistency, reliability, and convergent and divergent validity. The factor structure of the scale supports a tripartite model of stigma consisting of stereotyping, prejudice and discrimination. Stereotyping had the highest relative scores on the subscales, and attitudes regarding other viral STBBIs differed significantly from the other STBBI categories. CONCLUSION: The new scale provides a contextually relevant and applicable psychometrically valid tool to assess STBBI-related stigma among health and social service providers in Canada. The tool can be used to assess attitudes and beliefs, as well as guide self-assessment and possible trainings for providers.

RESUMEN

OBJECTIVE: In Brazil, universal provision of antiretroviral therapy (ART) has been guaranteed free of charge to eligible HIV-positive patients since December 1996. We sought to quantify the survival benefits of ART attributable to this programme. METHODS: We used a previously published microsimulation model of HIV disease and treatment (CEPAC-International) and data from Brazil to estimate life expectancy increase for HIV-positive patients initiating ART in Brazil. We divided the period of 1997 to 2014 into six eras reflecting increased drug regimen efficacy, regimen availability and era-specific mean CD4 count at ART initiation. Patients were simulated first without ART and then with ART. The 2014-censored and lifetime survival benefits attributable to ART in each era were calculated as the product of the number of patients initiating ART in a given era and the increase in life expectancy attributable to ART in that era. RESULTS: In total, we estimated that 598,741 individuals initiated ART. Projected life expectancy increased from 2.7, 3.3, 4.1, 4.9, 5.5 and 7.1 years without ART to 11.0, 17.5, 20.7, 23.0, 25.3, and 27.0 years with ART in Eras 1 through 6, respectively. Of the total projected lifetime survival benefit of 9.3 million life-years, 16% (or 1.5 million life-years) has been realized as of December 2014. CONCLUSIONS: Provision of ART through a national programme has led to dramatic survival benefits in Brazil, the majority of which are still to be realized. Improvements in initial and subsequent ART regimens and higher CD4 counts at ART initiation have contributed to these increasing benefits.

RESUMEN

Despite the existence of low-cost and effective interventions for childhood pneumonia and diarrhoea, these conditions remain two of the leading killers of young children. Based on feedback from health professionals in countries with high child mortality, in 2009, WHO and Unicef began conceptualising an integrated approach for pneumonia and diarrhoea control. As part of this initiative, WHO and Unicef, with support from other partners, conducted a series of five workshops to facilitate the inclusion of coordinated actions for pneumonia and diarrhoea into the national health plans of 36 countries with high child mortality. This paper presents the findings from workshop and post-workshop follow-up activities and discusses the contribution of these findings to the development of the integrated Global Action Plan for the Prevention and Control of Pneumonia and Diarrhoea, which outlines the necessary actions for elimination of preventable child deaths from pneumonia and diarrhoea by 2025. Though this goal is ambitious, it is attainable through concerted efforts. By applying the lessons learned thus far and continuing to build upon them, and by leveraging existing political will and momentum for child survival, national governments and their supporting partners can ensure that preventable child deaths from pneumonia and diarrhoea are eventually eliminated.

RESUMEN

It is evident that both tangible and intangible elements constitute heritage and this needs to be recognized by researchers, heritage professionals and government bodies charged with implementing development policies. However, the relationship between traditional beliefs, worldview, heritage conservation, and archaeological investigation is a complex one. This is considered with reference to the conflict that can occur between government policy and indigenous beliefs in relation to architecture, and with reference to perceptions of landscape amongst the Talensi communities of Tengzug in Upper East Region, Ghana.
