Abstract
AIM People living with mental illness are more likely than the general population to experience adverse housing outcomes, including homelessness. The aim of the current study is to examine residential status when participants have their first contact with mental health services, and the correlates of residential status at that moment. METHODS First-time mental health service users were recruited from seven clinical sites across Québec. Data on residential status at entry in the project, as well as demographic, clinical and social variables, were collected using self-report and interviewer-rated questionnaires. Participants were classified as 'Homeless', 'At risk of homelessness' and 'Stably Housed', and correlates of residential status were identified through multivariate logistic regression and unbiased recursive partitioning. RESULTS Among the 478 participants, 206 (43.1%) were in stable housing, 171 (35.8%) were at risk of homelessness and 101 (21.1%) were classified as homeless. Placement in a youth protection facility was strongly associated with adverse housing outcomes, while having a high school diploma and more social support were associated with more stable housing situations. CONCLUSIONS First-time mental health service users are likely to experience a range of adverse housing situations, indicating the potential for clinical sites to implement homelessness primary prevention strategies. Factors related to family, foster care and schooling seem to be particularly salient in understanding risk of homelessness in first-time mental health service users, calling for intersectoral action to prevent adverse psychosocial outcomes in this population.

Abstract
Transitional age youth experiencing homelessness (TAY-EH) represent an underserved and understudied population. While an increasing number of empirical interventions have sought to address the high burden of psychopathology in this population, findings remain mixed regarding intervention effectiveness. In this systematic review of behavioral health interventions for TAY-EH, we sought to examine the structural framework in which these interventions take place and how these structures include or exclude certain populations of youth. We also examined implementation practices to identify how interventions involving youth and community stakeholders effectively engage these populations. Based on PRISMA guidelines, searches of Medline, PsycInfo, Embase, Cochrane Central, Web of Science, and ClinicalTrials.gov databases were conducted, including English language literature published before October 2022. Eligible studies reported on interventions for adolescent or young adult populations ages 13-25 years experiencing homelessness. The initial search yielded 3850 citations; 353 underwent full text review and 48 met inclusion criteria, of which there were 33 unique studies. Studies revealed a need for greater geographic distribution of empirically based interventions, as well as interventions targeting TAY-EH in rural settings. Studies varied greatly regarding their operationalizations of homelessness and their method of intervention implementation, but generally indicated a need for increased direct-street outreach in participant recruitment and improved incorporation of youth feedback into intervention design. To our knowledge, this is the first systematic review to examine the representation of various groups of TAY-EH in the literature on substance use and mental health interventions. Further intervention research engaging youth from various geographic locations and youth experiencing different forms of homelessness is needed to better address the behavioral health needs of a variety of TAY-EH.

Abstract
BACKGROUND Assertive community treatment (ACT) is a multidisciplinary, team-based approach providing comprehensive individualized care for the patients with various mental illness, has been adapted variably across the world in terms of patient-staff ratio, selection of patients, the pattern of service delivery and frequency of contact. We aim to review the extant literature on the modifications of ACT programs for severe mental disorders and their effectiveness. METHODS Studies on modified ACT approaches for mental illnesses were searched in multiple databases. We adopted a rapid appraisal approach. The searches were restricted to articles published in English. We appraised the fidelity assessment of the ACT studies wherever available. In addition, we assessed the study quality using a grading tool based on ten practice components of ACT. RESULTS We found 23 reports (10 RCTs and 13 non-controlled studies) on modified ACT. The extant literature on modified ACT programs is heterogeneous. The modifications in ACT included changes in patient-to-staff ratio, team composition, service hours, and interventions carried out. Most controlled studies were conducted in high-income settings and had inconsistent outcome, possibly due to the comprehensive nature of the 'usual care.' In contrast, modified ACT services from low and middle-income countries reduced hospitalization rates and improved treatment adherence. CONCLUSIONS Modifications in ACT programs were done to cater to specific subpopulation and the changes in program structure to suit the resources and setting. The outcome of modified ACT appears heterogenous, though the findings from low and middle-income countries are promising.

Abstract
The population of persons of color (POC) are increasing in the United States. Unfortunately, POC are significantly impacted by serious mental illness; psychosis represents a mental health disparity among POC. Fortunately, first episode coordinated specialty care (CSC) is an effective treatment for individuals who are in the early phases of a psychotic disorder. This systematic review of the literature examined POC inclusion rates in randomized controlled trials (RCT) examining First Episode Psychosis (FEP) programs. Our review yielded seven articles that met inclusion criteria. Our findings were mixed-researchers conducting RCTs on FEP programs did an excellent job including African American participants suggesting that findings from RCTs on FEP programs may generalize to African American participants. Regarding Latines, they were broadly underrepresented in RCTs on FEP CSC. Based on the data, we cannot definitively conclude to what extent findings from RCTs on FEP CSC generalize to Latines although results from studies that included a reasonable number of Latines offer promising results. Asians were overrepresented in three of the seven studies included in this review; thus it seems that the findings from RCTs on FEP CSC generalize to the Asian population in the United States.

Abstract
AIM Approximately 50% of individuals with first-episode psychosis meet criteria for a substance use disorder and these concurrent disorders are associated with worse long-term outcomes. Psychosocial interventions, including motivational interviewing as well as cognitive and behavioural therapies, have shown some evidence for effective treatment in substance use disorders; however, there is a paucity of existing studies that have successfully examined these interventions in first-episode psychosis. METHODS Participants (n = 64) received the concurrent disorders intervention, which included individual support alongside participation in at least one of two groups: a 4-week Motivational Engagement group utilizing motivational interviewing (n = 59) and an 8-week Relapse Prevention Training group emphasizing skill acquisition, which some participants entered directly (n = 5) and some participants entered following completion of the Motivational Engagement group (n = 16). RESULTS Participants who completed the Motivational Engagement group (n = 59) demonstrated significantly increased motivation to change substance use (d = -.0.58; t = -3.02, p < .01) and significantly decreased substance use frequency (d = 0.65; t = 3.26, p < .01). For participants who completed the Relapse Prevention Training group (n = 21), substance use frequency significantly decreased (d = 0.92; t = 3.46, p < .01) and self-efficacy in one's ability to maintain substance use changes significantly increased (d = -0.85; t = -3.59, p < .01). CONCLUSIONS This pilot evaluation suggests that motivational interviewing and relapse prevention skills training are acceptable and feasible interventions in the treatment of substance use disorders in young adults with first-episode psychosis.

Abstract
OBJECTIVES Specialized early intervention for psychosis can reduce the duration of untreated psychosis and improve clinical and functional outcomes. However, poor adherence to treatment is frequent. The literature on community treatment orders (CTOs) use in first-episode psychosis (FEP) as a means to improve treatment adherence is limited. In the context of early intervention for psychosis services (EIS), this study aims to describe (1) the frequency of CTOs utilisation, (2) the trend of CTOs use over time, (3) the timing and reasons for requesting CTOs and (4) the baseline characteristics of FEP patients on CTOs compared to those who were not. METHOD A 5-year prospective longitudinal study describing the use of CTOs among persons with FEP admitted to two urban EIS in Montreal, Quebec, from 2005 to 2013. At admission, and then annually for 5 years, CTOs data were collected through chart review. Baseline characteristics, assessed by patient interviews, standardized questionnaires and chart review, included socio-demographic data, illness severity, functioning and alcohol and substance use. Descriptive analyses were performed, and FEP patients on CTOs during follow-up and those who were not were compared using analyses of variance, chi-square test and multivariate logistic regression. RESULTS Among 567 FEP patients, 19.2% were placed on CTOs. The main reasons for requesting CTOs were to prevent further deterioration in mental state, social functioning, harmful behaviours to self and others and homelessness. FEP patients on CTOs had poorer premorbid and baseline functioning, more severe symptoms and social dysfunction at admission, including legal problems and homelessness. CONCLUSIONS CTOs can be a tool to improve adherence to treatment, which is crucial for relapse prevention in FEP. However, since it is a coercive method that limits a person's fundamental rights, further research is warranted to assess its impact on patients' lives, clinical and functional outcomes, as well as patients' and carers' perception.

Abstract
Assertive Community Treatment (ACT) is a multidisciplinary treatment approach to support people with severe mental illnesses (SMI) in their recovery. While the majority of ACT recipients report co-morbid substance use issues, limited reviews have evaluated the impact of receiving ACT services on substance use outcomes. The purpose of this systematic review was to evaluate the impact of ACT involvement on substance use outcomes among people with SMI. A systematic literature search was conducted including articles published prior to April 2021. Twenty-nine studies were included in this review. Of them, 15 studies implemented a controlled design (six studies demonstrated high quality) and 14 studies implemented a cohort design. From a synthesis of the reviewed studies, five areas of changes associated with substance use emerged including reduced alcohol and drug use severity, lower prevalence of alcohol and drug use, increased stage of change in substance use treatment, and fewer days of hospitalization and intoxication. Thus, future studies should examine the integration of substance use treatment services as part of ACT interventions for opportunities to enhance recovery outcomes among individuals with SMI.

Filges T, Dalgaard NT, Viinholt BCA. Outreach programs to improve life circumstances and prevent further adverse developmental trajectories of at-risk youth in OECD countries: A systematic review. CAMPBELL SYSTEMATIC REVIEWS 2022; 18:e1282. [PMID: 36908846 PMCID: PMC9577261 DOI: 10.1002/cl2.1282] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Indexed: 06/18/2023]
Abstract
Background At-risk youth may be defined as a diverse group of young people in unstable life circumstances, who are currently experiencing or are at risk of developing one or more serious problems. At-risk youth are often very unlikely to seek out help for themselves within the established venues, as their adverse developmental trajectories have installed a lack of trust in authorities such as child protection agencies and social workers. To help this population, a number of outreach programmes have been established seeking to help the young people on an ad hoc basis, meaning that the interventions are designed to fit the individual needs of each young person rather than as a one-size-fits-all treatment model. The intervention in this review is targeted outreach work which may be (but does not have to be) multicomponent programmes in which outreach may be combined with other services. Objectives The main objective of this review was to answer the following research questions: What are the effects of outreach programmes on problem/high-risk behaviour of young people between 8 and 25 years of age living in OECD countries? Are they less likely to experience an adverse outcome such as school failure or drop-out, runaway and homelessness, substance and/or alcohol abuse, unemployment, long-term poverty, delinquency and more serious criminal behaviour? Search Methods We identified relevant studies through electronic searches of bibliographic databases, governmental and grey literature repositories, hand search in specific targeted journals, citation tracking, and Internet search engines. The database searches were carried out in September 2020 and other resources were searched in October and November 2021. We searched to identify both published and unpublished literature, and reference lists of included studies and relevant reviews were searched. Selection Criteria The intervention was targeted outreach work which may have been combined with other services. Young people between 8 and 25 years of age living in OECD countries, who either have experienced or is at-risk of experiencing an adverse outcome were eligible. Our primary focus was on measures of problem/high-risk behaviour and a secondary focus was on social and emotional outcomes. All study designs that used a well-defined control group were eligible for inclusion. Studies that utilised qualitative approaches were not included. Data Collection and Analysis The total number of potentially relevant studies constituted 17,659 hits. A total of 16 studies (17 different interventions) met the inclusion criteria. Only five studies could be used in the data synthesis. Eight studies could not be used in the data synthesis as they were judged to have critical risk of bias and, in accordance with the protocol, were excluded from the meta-analysis on the basis that they would be more likely to mislead than inform. Two studies (three interventions) did not provide enough information enabling us to calculate an effect size and standard error, and one study did not provide enough information to assess risk of bias. Meta-analysis of all outcomes were conducted on each conceptual outcome separately. All analyses were inverse variance weighted using random effects statistical models incorporating both the sampling variance and between study variance components into the study level weights. Random effects weighted mean effect sizes were calculated using 95% confidence intervals. Too few studies were included to carry out any sensitivity analyses. Main Results Four of the five studies used for meta analysis were from the USA and one was from Canada. The timespan in which included studies were carried out was 32 years, from 1985 to 2017; on average the intervention year was 2005. The average number of participants in the analysed interventions was 116, ranging from 30 to 346 and the average number of controls was 81, ranging from 32 to 321. At most, the results from two studies could be pooled in a single meta-analysis. It was only possible to pool the outcomes drug (other than marijuana) use, marijuana use and alcohol use each at two different time points (one and 3 months follow up). At 1 month follow up the weighted averages varied between zero and 0.05 and at 3 months follow up between -0.17 and 0.07. None of them were statistically significant. In addition, a number of other outcomes were reported in a single study only. Authors' Conclusions Overall, there were too few studies included in any of the meta-analyses in order for us to draw any conclusion concerning the effectiveness of outreach. The vast majority of studies were undertaken in the USA. The dominance of the USA as the main country in which outreach interventions meeting our inclusion criteria have been evaluated using rigorous methods and within our specific parameters clearly limits the generalisability of the findings. None of the studies, however, was considered to be of overall high quality in our risk of bias assessment and the process of excluding studies with critical risk of bias from the meta-analysis applied in this review left us with only five of a total of 16 possible studies to synthesise. Further, because too few studies reported results on the same type of outcome at most two studies could be combined in a particular meta-analysis. Given the limited number of rigorous studies available from countries other than the USA, it would be natural to consider conducting a series of randomised controlled trials evaluating the effectiveness of outreach for at-risk youth in countries outside the USA. The trial(s) should be designed, conducted and reported according to methodological criteria for rigour in respect of internal and external validity to achieve robust results and preferably reporting a larger number of outcomes.

Abstract
AIMS High rates of mental illness among individuals experiencing homelessness, as well as documented contacts with psychiatric services prior to episodes of homelessness, indicate that early intervention could play a key role in homelessness prevention. Decision-makers and clinical teams need longitudinal data on housing trajectories following initial contact with psychiatric services, as well as on predictors of risk of housing instability and homelessness. This paper describes the AMONT study, a mixed-methods naturalistic longitudinal cohort study of individuals identified as new psychiatric service users in seven clinical sites across the province of Québec (Canada). METHODS The goal of AMONT is to examine the housing situations of individuals over 36 months after their initial contact with psychiatric services, and to identify environmental and individual correlates and predictors of housing outcomes. Participants complete a broad battery of instruments at baseline and follow-up assessments after 24 and 36 months. We explore housing stability following an initial episode of psychiatric service use from the perspective of service users, family members, and service providers, through qualitative interviews. RESULTS AND CONCLUSIONS The findings from the AMONT study will yield a better understanding of the residential pathways of individuals with mental illness, from their first contact with psychiatric services and for 3 years subsequently. This will inform service providers, decision-makers and managers on the specific housing concerns and issues that affect first-time mental health service users. This in turn can lead to the development and implementation of evidence-informed practices and policies that aim to prevent instability and homelessness.

Abstract
Housing stability is a complex concept to measure. One set of factors under consideration are those based on a personal or subjective sense of stability. We explore the variables associated with subjective stability and explore how subjective stability relates to housing stability across time. We use data from longitudinal, mixed methods research with 85 young people exiting homelessness. We find that subjective stability is a meaningful construct that can be validated through qualitative and quantitative data. The construct is primarily linked to indicators of environmental and social wellbeing. Subjective stability is also one of the only variables with a significant relationship to T2 housing stability. Qualitative analysis is used to explore these relationships in more detail. We conclude that subjective stability can provide holistic insight into the complex life circumstances influencing housing stability. However, this strength introduces complexity in that subjective stability appears to be developed in comparison with past experiences, as well as feelings of forward momentum on goals beyond housing.

BACKGROUND Patients with medically-treated opioid overdose are at high risk for subsequent adverse outcomes, including repeat overdose. Understanding factors associated with repeat overdose can aid in optimizing post-overdose interventions. METHODS We conducted a longitudinal, retrospective cohort study using NJ Medicaid data from 2014 to 2019. Medicaid beneficiaries aged 12-64 with an index opioid overdose from 2015 to 2018 were followed for one year for subsequent overdose. Exposures included patient demographics; co-occurring medical, mental health, and substance use disorders; service and medication use in the 180 days preceding the index overdose; and MOUD following index overdose. RESULTS Of 4898 individuals meeting inclusion criteria, 19.6% had repeat opioid overdoses within one year. Index overdoses involving heroin/synthetic opioids were associated with higher repeat overdose risk than those involving prescription/other opioids only (HR = 1.44, 95% CI = 1.22-1.71). Risk was higher for males and those with baseline opioid use disorder diagnosis or ED visits. Only 21.7% received MOUD at any point in the year following overdose. MOUD was associated with a large decrease in repeat overdose risk among those with index overdose involving heroin/synthetic opioids (HR = 0.30, 95% CI = 0.20-0.46). Among those receiving MOUD at any point in follow-up, 10.5% (112/1065) experienced repeat overdose versus 22.1% (848/3833) for those without MOUD. CONCLUSIONS Repeat overdose was common among individuals with medically-treated opioid overdose. Risk factors for repeat overdose varied by type of opioid involved in index overdose, with differential implications for intervention. MOUD following index opioid overdose involving heroin/synthetic opioids was associated with reduced repeat overdose risk.

Abstract
Little is known about clinical presentation and cascade of care among patients living with HIV (PLWH) in Beirut, Lebanon. The study aims to examine the reasons for HIV testing and to evaluate the clinical characteristics of, predictors of advanced HIV stage at presentation in, and rates of ART initiation, retention in care, and viral load suppression among PLWH in Lebanon. We conducted a retrospective study of PLWH presenting to a tertiary-care centre-affiliated outpatient clinic from 2008 to 2016 with new HIV infection diagnoses. We identified a total of 423 patients: 89% were men, 55% were 30-50 years old, and 58% self-identified as men who have sex with men. About 35% of the patients had concurrent sexually transmitted diseases at the time of HIV diagnosis. Thirty percent of infection cases were identified by provider-initiated HIV testing, 36% of cases were identified by patient-initiated testing, and 34% of patients underwent testing for screening purposes. The proportion of individuals presenting with advanced HIV disease decreased from 40% in 2008-2009 to 24% in 2014-2015. Age older than 50 years and identification of HIV by a medical provider were independent predictors of advanced HIV infection at presentation. Among patients having indications for treatment (n = 253), 239 (94%) were prescribed antiretroviral therapy, and 147 (58%) had evidence of viral suppression at 1 year. Furthermore, 266 patients (63%) were retained in care. The care continuum for PLWH in Lebanon is comparable with those in high-income countries yet still far behind the Joint United Nations Programme on HIV/AIDS 90-90-90 set target.

Abstract
PURPOSE MYC-driven medulloblastomas are highly aggressive childhood tumors with dismal outcomes and a lack of new treatment paradigms. We identified that targeting replication stress through WEE1 inhibition to suppress the S-phase replication checkpoint, combined with the attenuation of nucleotide synthesis with gemcitabine, is an effective strategy to induce apoptosis in MYC-driven medulloblastoma that could be rapidly translated into early phase clinical trials in children. Attenuation of replication stress is a key component of MYC-driven oncogenesis. Previous studies revealed a vulnerability in MYC medulloblastoma through WEE1 inhibition. Here, we focused on elucidating combinations of agents to synergize with WEE1 inhibition and drive replication stress toward cell death. METHODS We first analyzed WEE1 expression in patient tissues by immunohistochemistry. Next, we used high-throughput drug screens to identify agents that would synergize with WEE1 inhibition. Synergy was confirmed by in vitro live cell imaging, ex vivo slice culture models, and in vivo studies using orthotopic and flank xenograft models. RESULTS WEE1 expression was significantly higher in Group 3 and 4 medulloblastoma patients. The WEE1 inhibitor AZD1775 synergized with inhibitors of nucleotide synthesis, including gemcitabine. AZD1775 with gemcitabine suppressed proliferation and induced apoptosis. Ex vivo modeling demonstrated efficacy in Group 3 medulloblastoma patients, and in vivo modeling confirmed that combining AZD1775 and gemcitabine effectively suppressed tumor growth. CONCLUSION Our results identified a potent new synergistic treatment combination for MYC-driven medulloblastoma that warrants exploration in early phase clinical trials.

Abstract
Social isolation is a major problem in the United States that has adverse impacts on health and well-being. However, few studies investigate social isolation among African Americans or the impact of social isolation on psychiatric disorders. This study addresses this gap by investigating the impact of objective (absence of contact with others) and subjective (lacking feelings of closeness to others) social isolation on psychiatric disorders among African Americans. The sample includes 3,570 African Americans from the National Survey of American Life. Regression models were used to test the impact of objective and subjective isolation on 12-month MDD, any 12-month DSM disorder and number of 12-month DSM disorders. Analyses indicated that subjective isolation from family only, friends only, and both groups were associated with greater odds of meeting criteria for 12-month MDD, any 12-month disorder and number of 12-month DSM disorders. However, objective isolation was unrelated to either measure of psychiatric disorder. Study findings indicate that affective characteristics of social isolation (feelings of closeness with family and friends) are more significant for psychiatric disorders than are objective features (social contact). Our discussion notes that the connections between subjective and objective social isolation and psychiatric disorders are complex and potentially reciprocally associated with one another. Clinical practice should focus on both possible associations.

Abstract
Youth homelessness is a complex phenomenon as well as an important public health issue often compounded by mental illness of varying severity, in turn creating numerous deleterious consequences. While emergency health services usage remains high, access to mental health services is arduous and conventional interventions often fall short on providing integrated care and seldom lead to sustained positive outcomes for this group. From this observation, clinicians in Montreal, Canada, initiated collaborative meetings, eventually attended by a growing number of institutional and community stakeholders working with homeless youth. Acknowledging the unique needs of this population, the Réseau d'intervention de proximité auprès des Jeunes de la Rue (RIPAJ) or Montreal Homeless Youth Network was created to engage and seamlessly connect youth with the right resources within the network including mental health services amongst others. The genesis, philosophy and unique features of RIPAJ that allow for effective and cohesive interventions as well as future directions are discussed.

Abstract
BACKGROUND Psychosis augments the risk of homelessness, the latter is associated with increased morbidity and mortality. Young adults experiencing first-episode psychosis (FEP) are increasingly recognized as being vulnerable to homelessness. However, data on homeless in youth with FEP are sparse. OBJECTIVES To compare symptomatic and functional outcomes in homeless v. never homeless FEP, at admission and two years after admission to an Early Psychosis Intervention Service (EIS). METHOD From October 2005 to April 2011, 167 FEP consecutive admissions (aged 18-30 years old), were recruited in a 2-year prospective longitudinal study in an inner city EIS in Montreal, Canada. Socio-demographic characteristics, symptomatic and functional outcomes, as well as treatments and service use data were collected at admission and annually. RESULT 26% of FEP were homeless, prior or during the follow-up. Attrition rate was similar among the two groups. At baseline, the homeless group were more likely to have childhood abuse, forensic history, non-affective psychosis, negative symptoms, substance use disorder and cluster B personality. Despite the intensive care of EIS, the similarity of illness severity at baseline and medication adherence rate, homeless FEP had poorer 2-year symptomatic and functional outcomes, although having more long-acting injectable antipsychotics (LAI) (vs oral antipsychotics), community treatment order and hospitalizations. CONCLUSION Homelessness is a serious and prevalent phenomenon among FEP youth associated with worse symptomatic and functional outcomes. More studies on interventions focusing on potentially modifiable factors (e.g. substance use disorders, social support) are warranted.

Abstract
Iron deficiency is a common etiology of anemia that causes suboptimal response to erythropoietin therapy in hemodialysis (HD) patients. This study investigated the association between vitamin D receptor (VDR) genetic variant (FokI) rs2228570 with iron indices (serum iron, transferrin, transferrin saturation, and ferritin). Sixty adequately hemodialyzed patients subdivided into two groups; 31 patients with transferrin saturation (TSAT) < 20% and 29 with TSAT > 20% who received I.V sodium ferric gluconate, calcium, and vitamin D. Sixty normal healthy were selected as the control group.. VDR genetic variant (SNP rs2228570) was genotyped in all subjects using PCR/RFLP. HD patients showed a higher frequency of rs2228570 FF genotype (38.3%) than controls (31.7%). The frequency of ff genotype and f allele in patients (8.4 and 35% respectively) were significantly lower than controls (25 and 46.7% respectively). Allele model (f vs. F): OR 0.721, 95% CI 0.521-0.998, P = 0.049. While (ff vs. FF): OR 0.452, 95% CI 0.223-0.917, P = 0.028. The distribution of Ff + ff genotypes in HD cases with TSAT > 20% was higher than in HD cases with TSAT < 20%, Dominant model (Ff +ff vs FF): OR 2.753, 95% CI 1.902-3.409, P = 0.048. f allele showed lower frequency in low TSAT group than high TSAT group (27.4 vs. 43.1%) with significant P value (P = 0.042) with allele model (f vs. F): OR 2.012, 95% CI 1.923-4.226, P = 0.042. Fok-1 ff, Ff + ff genotypes were significantly associated with TSAT > 20% with a protective effect against low TSAT in HD patients.

Abstract
PURPOSE The purpose of this paper is to provide a brief overview of economic analysis methods used in estimating the costs and benefits of public health programs and systematically review the application of these methods to the National Breast and Cervical Cancer Early Detection Program (NBCCEDP). METHODS Published literature on economic analyses of the NBCCEDP was systematically reviewed. The Consensus on Health Economic Criteria checklist was used to assess methodological quality of the included studies. RESULTS Methods available for economic analysis of public health programs include program cost, cost-effectiveness, cost-utility, cost-benefit analysis, and budget impact analysis. Of these, program cost analysis, cost-effectiveness analysis, and cost-utility analysis have been applied to the NBCCEDP in previously published literature. CONCLUSION While there have been multiple program cost analyses, there are relatively fewer cost-effectiveness and cost-utility studies and no cost-benefit and budget impact analysis studies to evaluate the NBCCEDP. Addressing these gaps will inform implementation of effective public health programs with equitable resource allocation to all population subgroups.

Abstract
The striatum is an essential component of the basal ganglia that regulatessensory processing, motor, cognition, and behavior. Depending on the species, the striatum shows a unique structure called caudate-putamen as in mice, or its separation into two regions called caudate and lenticular nuclei, the latter formed by putamen and globus pallidus areas, as in primates. These structures have two compartments, striosome and matrix. We investigated the structural organization, GABAergic and tyrosine hydroxylase (TH) expression in the striatum and globus pallidus of the South American plains vizcacha, Lagostomus maximus. Its striatum showed regionalization arising from the presence of an internal capsule, and a similar organization to a striosome-matrix compartmentalization. GABAergic neurons in the matrix of caudate exhibited parvalbumin, calretinin, calbindin, GAD65, and NADPH-d-immunoreactivity. These were also expressed in cells of the putamen with the exception of calretinin showing neurofibers localization. Globus pallidus showed parvalbumin- and GAD65-immunoreactive cells, and calretinin- and calbindin-immunoreactive neuropil, plus GABA-A-immunoreactive neurofibers. NADPH-d-, GAD65- and GABA-A-immunoreactive neurons were larger than parvalbumin-, calretinin-, and calbindin-immunoreactive cells, whereas calbindin-immunoreactive cells were the most abundant. In addition, TH-immunoreactive neuropil was observed in the matrix of the striatum. A significant larger TH-immunoreactive area and neuron number was found in females compared to males. The presence of an internal capsule suggests an adaptive advantage concerning motor and cognitive abilities favoring reaction time in response to predators. In an anatomy-evolutive perspective, the striatum of vizcacha seems to be closer to that of humans than to that of laboratory traditional models such as mouse.
