Direct and indirect links between children's socio-economic status and education: pathways via mental health, attitude, and cognition.

A child's socio-economic environment can profoundly affect their development. While existing literature focusses on simplified metrics and pair-wise relations between few variables, we aimed to capture complex interrelationships between several relevant domains using a broad assessment of 519 children aged 7-9 years. Our analyses comprised three multivariate techniques that complimented each other, and worked at different levels of granularity. First, an exploratory factor analysis (principal component analysis followed by varimax rotation) revealed that our sample varied along continuous dimensions of cognition, attitude and mental health (from parallel analysis); with potentially emerging dimensions speed and socio-economic status (passed Kaiser's criterion). Second, k-means cluster analysis showed that children did not group into discrete phenotypes. Third, a network analysis on the basis of bootstrapped partial correlations (confirmed by both cross-validated LASSO and multiple comparisons correction of binarised connection probabilities) uncovered how our developmental measures interconnected: educational outcomes (reading and maths fluency) were directly related to cognition (short-term memory, number sense, processing speed, inhibition). By contrast, mental health (anxiety and depression symptoms) and attitudes (conscientiousness, grit, growth mindset) showed indirect relationships with educational outcomes via cognition. Finally, socio-economic factors (neighbourhood deprivation, family affluence) related directly to educational outcomes, cognition, mental health, and even grit. In sum, cognition is a central cog through which mental health and attitude relate to educational outcomes. However, through direct relations with all components of developmental outcomes, socio-economic status acts as a great 'unequaliser'.

Chicago's Citywide COVID-19 Vaccine Equity Program: Protect Chicago Plus.

Vaccination is one of the most effective strategies to control the spread of COVID-19 and reduce morbidity and mortality; however, rapid and equitable vaccine distribution is required to achieve such outcomes. We conducted a basic interrupted time-series analysis to examine the short-term impacts of a citywide vaccine equity plan, the Protect Chicago Plus (PCP) plan. We compared vaccine coverage in zip codes in Chicago with high COVID-19 vulnerability, as identified from the Chicago COVID-19 Community Vulnerability Index, with coverage in all other zip codes in Chicago. From our analysis, we observed that implementation of PCP coincided with reduced vaccination disparities between Chicago communities with low and high vulnerability indexes over time. In our analysis of vaccination coverage before program implementation, vaccination coverage climbed nearly twice as fast among non-PCP zip codes (0.19% per day) than among PCP zip codes (0.10% per day) or by 0.09 percentage points (P < .001). In model analysis after program implementation, zip codes prioritized for the program had 0.42% additional coverage per day as compared with 0.27% per day for non-PCP zip codes. Our findings suggest that such programs may improve vaccine equity, but additional research is needed to better understand the longer-term effects of citywide vaccination strategies on vaccine uptake.

Poor disease knowledge is associated with higher healthcare service use and costs among patients with cirrhosis: an exploratory study.

BACKGROUND: Optimal management of cirrhosis is complex, and patients often lack knowledge and skills, which can affect self-management. We assessed patient knowledge about cirrhosis and examined whether knowledge was associated with clinical outcomes, healthcare service use, and healthcare costs. A cross-sectional 'knowledge survey' was conducted during 2018-2020. We assessed patient knowledge about cirrhosis and explore whether knowledge was associated with clinical outcomes, healthcare service use, and costs. METHODS: Patients with cirrhosis (n = 123) completed a 'knowledge survey'. We calculated the proportion of correct answers to eight questions deemed to be "key knowledge" about cirrhosis by an expert panel, and dichotomized patients as 'good knowledge'/'poor knowledge'. Clinical data, healthcare costs, and health-related quality of life (SF-36) were available. RESULTS: 58.5% of patients had 'good knowledge' about cirrhosis. Higher education level was associated with higher odds of having 'good knowledge' about cirrhosis (adjusted-OR = 5.55, 95%CI 2.40-12.84). Compared to patients with 'poor knowledge', those with 'good knowledge' had a higher health status in the SF-36 physical functioning domain (p = 0.011), fewer cirrhosis-related admissions (adjusted incidence rate ratio [IRR] = 0.59, 95%CI 0.35-0.99) and emergency presentations (adj-IRR = 0.34, 95%CI 0.16-0.72), and more planned 1-day cirrhosis admissions (adj-IRR = 3.96, 95%CI 1.46-10.74). The total cost of cirrhosis admissions was lower for patients with 'good knowledge' (adj-IRR = 0.30, 95%CI 0.29-0.30). CONCLUSION: Poor disease knowledge is associated with increased use and total cost of healthcare services. Targeted educational interventions to improve patient knowledge may be an effective strategy to promote a more cost-effective use of healthcare services.

Towards collaborative management of non-alcoholic fatty liver disease: a 'real-world' pathway for fibrosis risk assessment in primary care.

BACKGROUND: The optimal strategy to support primary care practitioners (PCP) to assess fibrosis severity in non-alcoholic fatty liver disease (NAFLD) and thereby make appropriate management decisions remains unclear. AIMS: To examine the feasibility of using a two-step pathway that combined simple scores (NAFLD Fibrosis Score and Fibrosis-4 Index) with transient elastography (FibroScan) to streamline NAFLD referrals from a 'routine' primary care population to specialist hepatology management clinics (HMC). METHODS: The two-step 'Towards Collaborative Management of NAFLD' (TCM-NAFLD) fibrosis risk assessment pathway was implemented at two outer metropolitan primary healthcare practices in Brisbane. Patients aged ≥18 years with a new or established PCP-diagnosis of NAFLD were eligible for assessment. The pathway triaged patients at 'high risk' of clinically significant fibrosis to HMC for specialist review, and 'low risk' patients to receive ongoing management and longitudinal follow up in primary care. RESULTS: A total of 162 patient assessments between June 2019 and December 2020 were included. Mean age was 58.7 ± 11.7 years, 30.9% were male, 54.3% had type 2 diabetes or impaired fasting glucose, and mean body mass index was 34.2 ± 6.9 kg/m2 . A total 122 patients was considered 'low risk' for clinically significant fibrosis, two patients had incomplete assessments and 38 (23.5%) were triaged to HMC. Among 31 completed HMC assessments to date, 45.2% were considered to have clinically significant (or more advanced) fibrosis, representing 9.2% of 153 completed assessments. CONCLUSION: Implementation of the two-step TCM-NAFLD pathway streamlined hepatology referrals for NAFLD and may facilitate a more cost-effective and targeted use of specialist hepatology resources.

COVID-19 health inequities and association with mechanical ventilation and prolonged length of stay at an urban safety-net health system in Chicago.

Millions of Americans have been infected with COVID-19 and communities of color have been disproportionately burdened. We investigated the relationship between demographic characteristics and COVID-19 positivity, and comorbidities and severe COVID-19 illness (use of mechanical ventilation and length of stay) within a racial/ethnic minority population. Patients tested for COVID-19 between March 2020 and January 2021 (N = 14171) were 49.9% (n = 7072) female; 50.1% (n = 7104) non-Hispanic Black; 33.2% (n = 4698) Hispanic; and 23.6% (n = 3348) aged 65+. Overall COVID-19 positivity was 16.1% (n = 2286). Compared to females, males were 1.1 times more likely to test positive (p = 0.014). Compared to non-Hispanic Whites, non-Hispanic Black and Hispanic persons were 1.4 (p = 0.003) and 2.4 (p<0.001) times more likely, respectively, to test positive. Compared to persons ages 18-24, the odds of testing positive were statistically significantly higher for every age group except 25-34, and those aged 65+ were 2.8 times more likely to test positive (p<0.001). Adjusted for race, sex, and age, COVID-positive patients with chronic obstructive pulmonary disease were 1.9 times more likely to require a ventilator compared to those without chronic obstructive pulmonary disease (p = 0.001). Length of stay was not statistically significantly associated with any of the comorbidity variables. Our findings emphasize the importance of documenting COVID-19 disparities in marginalized populations.

ADVANCE integrated group intervention to address both substance use and intimate partner abuse perpetration by men in substance use treatment: a feasibility randomised controlled trial.

BACKGROUND: Substance use is a risk factor for intimate partner abuse (IPA) perpetration. Delivering perpetrator interventions concurrently with substance use treatment shows promise. METHODS: The feasibility of conducting an efficacy and cost-effectiveness trial of the ADVANCE 16-week intervention to reduce IPA by men in substance use treatment was explored. A multicentre, parallel group individually randomised controlled feasibility trial and formative evaluation was conducted. Over three temporal cycles, 104 men who had perpetrated IPA towards a female (ex) partner in the past year were randomly allocated to receive the ADVANCE intervention + substance use treatment as usual (TAU) (n = 54) or TAU only (n = 50) and assessed 16-weeks post-randomisation. Participants' (ex) partners were offered support and 27 provided outcome data. Thirty-one staff and 12 men who attended the intervention participated in focus groups or interviews that were analysed using the framework approach. Pre-specified criteria assessed the feasibility of progression to a definitive trial: 1) ≥ 60% of eligible male participants recruited; 2) intervention acceptable to staff and male participants; 3) ≥ 70% of participants followed-up and 4) levels of substance use and 5) IPA perpetrated by men in the intervention arm did not increase from average baseline level at 16-weeks post-randomisation. RESULTS: 70.7% (104/147) of eligible men were recruited. The formative evaluation confirmed the intervention's acceptability. Therapeutic alliance and session satisfaction were rated highly. The overall median rate of intervention session attendance (of 14 compulsory sessions) was 28.6% (range 14.3-64.3% by the third cycle). 49.0% (51/104) of men and 63.0% (17/27) of their (ex) partners were followed-up 16-weeks post-randomisation. This increased to 100% of men and women by cycle three. At follow-up, neither substance use nor IPA perpetration had worsened for men in the intervention arm. CONCLUSIONS: It was feasible to deliver the ADVANCE intervention in substance use treatment services, although it proved difficult to collect data from female (ex)partners. While some progression criteria were met, others were not, although improvements were demonstrated by the third cycle. Lessons learned will be implemented into the study design for a definitive trial of the ADVANCE intervention. TRIAL REGISTRATION: ISRCTN79435190 prospectively registered 22nd May 2018.

Hospice care for end stage liver disease in the United States.

INTRODUCTION: Patients with end-stage liver disease (ESLD) have impaired physical, psychological, and social functions, which can diminish patient quality of life, burden family caregivers, and increase health-care utilization. For those with a life expectancy of less than six months, these impairments and their downstream effects can be addressed effectively through high-quality hospice care, delivered by multidisciplinary teams and focused on the physical, emotional, social, and spiritual wellbeing of patients and caregivers, with a goal of improving quality of life. AREAS COVERED: In this review, we examine the evidence supporting hospice for ESLD, we compare this evidence to that supporting hospice more broadly, and we identify potential criteria that may be useful in determining hospice appropriateness. EXPERT OPINION: Despite the potential for hospice to improve care for those at the end of life, it is underutilized for patients with ESLD. Increasing the appropriate utilization of hospice for ESLD requires a better understanding of patient eligibility, which can be based on predictors of high short-term mortality and liver transplant ineligibility. Such hospice criteria should be data-driven and should accommodate the uncertainty faced by patients and physicians.

Far and wide: Associations between childhood socio-economic status and brain connectomics.

Previous studies have identified localized associations between childhood environment - namely their socio-economic status (SES) - and particular neural structures. The primary aim of the current study was to test whether associations between SES and brain structure are widespread or limited to specific neural pathways. We employed advances in whole-brain structural connectomics to address this. Diffusion tensor imaging was used to construct whole-brain connectomes in 113 6-12 year olds. We then applied an adapted multi-block partial-least squares (PLS) regression to explore how connectome organisation is associated with childhood SES (parental income, education levels, and neighbourhood deprivation). The Fractional Anisotropy (FA) connectome was significantly associated with childhood SES and this effect was widespread. We then pursued a secondary aim, and demonstrated that the connectome mediated the relationship between SES and cognitive ability (matrix reasoning and vocabulary). However, the connectome did not significantly mediate SES relationships with academic ability (maths and reading) or internalising and externalising behavior. This multivariate approach is important for advancing our theoretical understanding of how brain development may be shaped by childhood environment, and the role that it plays in predicting key outcomes. We also discuss the limitations with this new methodological approach.

Migraine diagnosis and treatment: A knowledge and needs assessment of women's healthcare providers.

BACKGROUND: Studies suggest that migraine is often underdiagnosed and inadequately treated in the primary care setting, despite many patients relying on their primary care provider (PCP) to manage their migraine. Many women consider their women's healthcare provider to be their PCP, yet very little is known about migraine knowledge and practice patterns in the women's healthcare setting. OBJECTIVE: The objective of this study was to assess women's healthcare providers' knowledge and needs regarding migraine diagnosis and treatment. METHODS: The comprehensive survey assessing migraine knowledge originally developed for PCPs was used in this study, with the addition of a section regarding the use of hormonal medications in patients impacted by migraine. Surveys were distributed online, and primarily descriptive analyses were performed. RESULTS: The online survey was completed by 115 women's healthcare providers (response rate 28.6%; 115/402), who estimated that they serve as PCPs for approximately one-third of their patients. Results suggest that women's healthcare providers generally recognize the prevalence of migraine, but experience some knowledge gaps regarding migraine management. Despite 82.6% (95/115) of survey respondents feeling very comfortable or somewhat comfortable with diagnosing migraine, only 57.9% (66/114) reported routinely asking patients about headaches during annual visits. Very few were familiar with the American Academy of Neurology guidelines on preventative treatment (6.3%; 7/111) and the Choosing Wisely Campaign recommendations on migraine treatment (17.3%; 19/110), and many prescribed medications known to contribute to medication overuse headache. In addition, only 24.3% (28/115) would order imaging for a new type of headache, 35.7% (41/115) for worsening headache, and 47.8% (55/115) for headache with neurologic symptoms; respondents cited greater tendency with sending patients to an emergency department for the same symptoms. Respondents had limited knowledge of evidence-based, non-pharmacological treatments for migraine (i.e., biofeedback or cognitive behavioral therapy), with nearly none placing referrals for these services. Most providers were comfortable prescribing hormonal contraception (mainly progesterone only) to women with migraine without aura (80.9%; 89/110) and with aura (72.5%; 79/109), and followed American College of Obstetricians and Gynecologists (ACOG) guidelines to limit combination hormonal contraception for patients with aura. When queried, 6.3% or less (5/79) of providers would prescribe estrogen-containing contraception for women with migraine with aura. Only 37.3% (41/110) of respondents reported having headache/migraine education. Providers indicated interest in education pertaining to migraine prevention and treatment (96.3%; 105/109), migraine-associated disability (74.3%; 81/109), and diagnostic testing (59.6%; 65/109). CONCLUSION: Women's healthcare providers appear to have several knowledge gaps regarding the management of migraine in their patients. These providers would likely benefit from access to a headache-specific educational curriculum to improve provider performance and patient outcomes.

Use of mean platelet volume in the assessment of intrauterine infection in newborns with combined thrombocytopenia and leukopenia at birth.

Objective: Intrauterine stress can be reflected on hematological disturbance at birth. Thrombocytopenia and leukopenia may be a result of exposure to maternal hypertensive disorders but may also indicate fetal inflammatory response to intrauterine infection, prompting empiric antibiotics use during the initial assessment after birth. Emerging data suggest long-term adverse health outcomes associated with antibiotics exposure early in life. In this report, we sought to assess the use of mean platelet volume (MPV) at birth in predicting fetal inflammatory response in newborns with combined thrombocytopenia and leukopenia.Materials and methods: This is a retrospective study from a single academic medical center. Data were collected prospectively on all newborns with thrombocytopenia and leukopenia within the first 24 h of life. The primary outcome was a composite of fetal tachycardia, premature preterm rupture of membrane with preterm labor, and histological evidence of chorioamnionitis/funisitis/villitis on placental pathology reports evaluated using a multiple logistical regression analysis.Results: The prevalence of combined thrombocytopenia and leukopenia was 5.8% (99 out of 1693 newborns) during the study period. The prevalence was highly associated with gestational age (R2 = 0.873). Twenty-four (32.4%) had abnormal MPV values at birth, defined as MPV > 9 or < 7 fL. Newborns with abnormal MPV had lower platelet counts and were more likely to have I:T ratio ≥0.2. In a univariate analysis, abnormal MPV (OR: 6.205, 95% CI: 1.923-20.022, p = .002), I:T ratio ≥0.2 (OR: 8.462, 95% CI: 1.396-51.281, p = .02), and platelet counts (OR: 98.4, 95% CI: 96.9%-99.9%, p = .035) were each significantly associated with a positive composite outcome. In a multivariate analysis, only abnormal MPV remained significantly associated with an increased likelihood of having a positive composite outcome, with an OR of 3.922 (95% CI: 1.094-14.06, p = .036).Conclusions: MPV may be a more reliable marker than I:T ratio ≥0.2 for fetal inflammatory response in newborns with combined thrombocytopenia and leukopenia during the initial assessment of intrauterine infection. Future prospective studies are required to confirm findings from this report.

Evidence of Social and Structural COVID-19 Disparities by Sexual Orientation, Gender Identity, and Race/Ethnicity in an Urban Environment.

The ongoing COVID-19 pandemic has had widespread social, psychological, and economic impacts. However, these impacts are not distributed equally: already marginalized populations, specifically racial/ethnic minority groups and sexual and gender minority populations, may be more likely to suffer the effects of COVID-19. The COVID-19 Resiliency Survey was conducted by the city of Chicago to assess the impact of COVID-19 on city residents in the wake of Chicago's initial lockdown, with particular focus on the experiences of minority populations. Chi-square tests of independence were performed to compare COVID-19-related outcomes and impacts on heterosexual vs. sexual minority populations, cisgender vs. gender minority populations, and White vs. racial/ethnic minority subgroups. Marginalized populations experienced significant disparities in COVID-19 exposure, susceptibility, and treatment access, as well as in psychosocial effects of the pandemic. Notably, Black and Latinx populations reported significant difficulties accessing food and supplies (p = 0.002). Healthcare access disparities were also visible, with Black and Latinx respondents reporting significantly lower levels of access to a provider to see if COVID-19 testing would be appropriate (p = 0.013), medical services (p = 0.001), and use of telehealth for mental health services (p = 0.001). Sexual minority respondents reported significantly lower rates of using telehealth for mental health services (p = 0.011), and gender minority respondents reported significantly lower levels of primary care provider access (p = 0.016). There are evident COVID-19 disparities experienced in Chicago especially for Black, Latinx, sexual minority, and gender minority groups. A greater focus must be paid to health equity, including providing increased resources and supplies for affected groups, adapting to inequities in the built environment, and ensuring adequate access to healthcare services to ameliorate the burden of COVID-19 on these marginalized populations.

ICD-10-AM codes for cirrhosis and related complications: key performance considerations for population and healthcare studies.

OBJECTIVE: The utility of International Classification of Diseases (ICD) codes relies on the accuracy of clinical reporting and administrative coding, which may be influenced by country-specific codes and coding rules. This study explores the accuracy and limitations of the Australian Modification of the 10th revision of ICD (ICD-10-AM) to detect the presence of cirrhosis and a subset of key complications for the purpose of future large-scale epidemiological research and healthcare studies. DESIGN/METHOD: ICD-10-AM codes in a random sample of 540 admitted patient encounters at a major Australian tertiary hospital were compared with data abstracted from patients' medical records by four blinded clinicians. Accuracy of individual codes and grouped combinations was determined by calculating sensitivity, positive predictive value (PPV), negative predictive value and Cohen's kappa coefficient (κ). RESULTS: The PPVs for 'grouped cirrhosis' codes (0.96), hepatocellular carcinoma (0.97) ascites (0.97) and 'grouped varices' (0.95) were good (κ all >0.60). However, codes under-detected the prevalence of cirrhosis, ascites and varices (sensitivity 81.4%, 61.9% and 61.3%, respectively). Overall accuracy was lower for spontaneous bacterial peritonitis ('grouped' PPV 0.75; κ 0.73) and the poorest for encephalopathy ('grouped' PPV 0.55; κ 0.21). To optimise detection of cirrhosis-related encounters, an ICD-10-AM code algorithm was constructed and validated in an independent cohort of 116 patients with known cirrhosis. CONCLUSION: Multiple ICD-10-AM codes should be considered when using administrative databases to study the burden of cirrhosis and its complications in Australia, to avoid underestimation of the prevalence, morbidity, mortality and related resource utilisation from this burgeoning chronic disease.

1D and 2D error assessment and correction for extrusion-based bioprinting using process sensing and control strategies.

The bioprinting literature currently lacks: (i) process sensing tools to measure material deposition, (ii) performance metrics to evaluate system performance, and (iii) control tools to correct for and avoid material deposition errors. The lack of process sensing tools limits in vivo functionality of bioprinted parts since accurate material deposition is critical to mimicking the heterogeneous structures of native tissues. We present a process monitoring and control strategy for extrusion-based fabrication that addresses all three gaps to improve material deposition. Our strategy uses a non-contact laser displacement scanner that measures both the spatial material placement and width of the deposited material. We developed a custom image processing script that uses the laser scanner data and defined error metrics for assessing material deposition. To implement process control, the script uses the error metrics to modify control inputs for the next deposition iteration in order to correct for the errors. A key contribution is the definition of a novel method to quantitatively evaluate the accuracy of printed constructs. We implement the process monitoring and control strategy on an extrusion-printing system to evaluate system performance and demonstrate improvement in both material placement and material width.

Application of a Multisite Empowerment Evaluation Approach to Increase Evaluation Capacity Among HIV Services Providers: Results From Project Pride in Chicago.

In 2015, the Centers for Disease Control and Prevention (CDC) funded Project PrIDE, a national initiative to implement and evaluate demonstration projects to increase PrEP uptake among HIV-negative individuals and to re-engage HIV-positive individuals in HIV care. Our team served as the Evaluation Center for Project PrIDE organizations in Chicago and used an empowerment evaluation (EE) approach to enhance evaluation capacity at these organizations. To evaluate our approach, we assessed organizations' evaluation capacity and engagement in technical assistance and capacity building activities in 2016 and 2018. Respondents who self-reported higher engagement with the Evaluation Center and who spent a greater number of hours engaged with our evaluators experienced greater increases in evaluation capacity tied to implementation of evaluation activities and technical assistance utilization. These findings demonstrate that multisite EE can be successfully applied to increase the evaluation capacity of organizations providing both HIV prevention and care services.

Club Fit: Development of a Physical Activity and Healthy Eating Intervention at a Boys & Girls Club After School Program.

Children and adolescents from minority and low income backgrounds face social and environmental challenges to engaging in physical activity and healthy eating to maintain a healthy weight. In this study, we present pilot work to develop and implement a multi-component physical activity and healthy eating intervention at a Boys & Girls Club (BGC) afterschool program. Using a community-based participatory approach, BGC staff and academic researchers developed intervention components informed by formative studies and based on a Social Ecological Theory framework. Components included healthy eating and physical activity policy implementation, staff training, a challenge and self-monitoring program for healthy behaviors, a peer-coaching program for healthy behaviors, and a social marketing campaign. We assessed pilot feasibility through a single group, pre-post study design with measures collected at baseline and 6 months. The sample included 61 children with a mean age of 10.4 years. Mean (SD) body mass index (BMI) percentile was 72.8 (28.9); 47.5% were in the healthy weight range for their age. We found statistically significant improvements of self-efficacy and motivation for physical activity. Self-efficacy and motivation for fruit and vegetable consumption, sugary beverage consumption, and screen time improved but were not statistically different from baseline. We found no improvements of perceived social support, objectively measured physical activity, or self-reported dietary quality. Though BMI did not improve overall, a dose effect was observed such that attendance in Club Fit specific programming was significantly correlated with decreased BMI z scores. Processes and products from this study may be helpful to other communities aiming to address childhood obesity prevention through afterschool programs.

Awareness and Intent to Use Pre-exposure Prophylaxis (PrEP) Among African American Women in a Family Planning Clinic.

Due to the gap between cisgender women eligible for and those accessing pre-exposure prophylaxis (PrEP) for HIV prevention, it is critical to understand knowledge of and attitudes toward PrEP among HIV-vulnerable women. PrEP utilization is particularly low among African American women in the USA. Family planning clinics provide key access points to reach HIV-vulnerable African American women as well as to translate research findings into clinical practice. Our study aimed to (1) describe the awareness of and interest in PrEP among African American cisgender women attending a family planning clinic and (2) document the barriers and facilitators to PrEP uptake among these women. A cross-sectional survey was conducted with sexually active African American women of reproductive age attending a family planning clinic. Descriptive statistics were used to characterize the sample, and bivariate analysis was used to detect difference between categorical and outcome variables. In our survey (N = 109), over 80% of participants listed not knowing PrEP was available as the primary reason for not currently taking PrEP. Seventy percent reported they would probably or definitely like to take PrEP - demonstrating that barriers to uptake might stem from knowledge deficits rather than attitudes toward prevention. Study findings have the potential to inform strategies to increase awareness of PrEP as an HIV prevention option as well as to equip women with greater self-efficacy to access PrEP in family planning settings.

Cues play a critical role in estrous cycle-dependent enhancement of cocaine reinforcement.

While preclinical work has aimed to outline the neural mechanisms of drug addiction, it has overwhelmingly focused on male subjects. There has been a push in recent years to incorporate females into existing addiction models; however, males and females often have different behavioral strategies, making it important to not only include females, but to develop models that assess the factors that comprise female drug addiction. Traditional self-administration models often include light or tone cues that serve as discriminative stimuli and/or consequent stimuli, making it nearly impossible to disentangle the effects of cue learning, the cues themselves, and acute effects of psychostimulant drugs. To disentangle the interaction between drug-associated cues and the consummatory and appetitive responding driven by cocaine, we have developed a new behavioral procedure that combines Pavlovian-instrumental transfer with behavioral economic analysis. This task can be completed within a single session, allowing for studies looking at estrous cycle stage-dependent effects in intact cycling females, something that has been difficult in the past. In this study, we found no differences in self-administration across the estrous cycle in the absence of cues; however, when cues were introduced, the cues that acquired value during estrus-but not during diestrus or in males-increased motivation. Cues paired during estrus also increased c-fos expression to a greater extent in striatal regions, an effect that may underlie the observed increases in seeking induced by these cues, even weeks later. Together, these data suggest that fundamental differences in the motivational properties of psychostimulant drugs between males and females are complex and are driven primarily by the interaction between drug-associated stimuli and drug effects.

Evaluation capacity building-Results and reflections across two years of a multisite empowerment evaluation in an HIV prevention context.

As the need for rigorous evidence of program efficacy increases, integrating evaluation activities into program implementation is becoming crucial. As a result, external evaluators are placing increased focus on evaluation capacity building as a practice. However, empirical evidence of how to foster evaluation capacity in different contexts remains limited. This study presents findings from an evaluation capacity survey conducted within a multisite Empowerment Evaluation initiative, in which an external evaluator worked with 20 project teams at diverse community agencies implementing HIV prevention projects. Survey results revealed representatives from project teams (n = 33) reported significantly higher overall evaluation capacity after engaging with the external evaluator on planning and implementing their evaluation. Improvements differed across organization type, intervention type, staff position, and reported engagement on various activities throughout the course of the evaluation. Results indicated empowerment evaluation and other stakeholder-focused evaluation approaches are broadly applicable when evaluation capacity building is a desired outcome, particularly when able to engage project staff in the planning of the evaluation and in delivering technical assistance services. Accordingly, efforts should be made by program funders, staff, and evaluators to encourage active engagement starting in the early stages of program and evaluation planning.

Pharmacogenomics Can Enhance Prescribing of Psychiatric Medications.

Many psychiatric patients experience pharmaceutical intolerances, and some of them do not derive optimal efficacy from their pharmacotherapies. Clinical problems such as these may result in prolonged dysfunction, adverse consequences, and repeated changes in medication treatment regimens. Pharmacogenomics is a laboratory method that aids individualized medication selection by predicting drug efficacy and adverse effect profiles. It is a technique that involves the testing of patients' genetic makeup to improve medicinal response and tolerance. Pharmacogenomics aims to clarify pharmacokinetics and pharmacodynamics in addition to focusing on hepatic cytochrome enzyme metabolism. Ultimately, it facilitates optimal selection and adjustment of medications to enhance clinical outcomes. Pharmacogenomics is most useful in cases in which routinely prescribed pharmacotherapies are either suboptimally effective or have unacceptable adverse effects. Once there has been a failure of a therapeutic drug treatment, rather than "blindly" selecting an alternative medicine, pharmacogenomic test results can provide guidance for the selection of the most appropriate drug and its dose. The intent is to yield a greater likelihood of patient success in following a therapeutic intervention.
