Cost-effectiveness study of FIB-4 followed by transient elastography screening strategy for advanced hepatic fibrosis in a NAFLD at-risk population.

BACKGROUND & AIMS: The cost-effectiveness to screen hepatic fibrosis in at-risk population as recommended by several professional societies has been limited. This study aimed to investigate the cost-effectiveness of this screening strategy in the expanded at-risk population recently proposed by several societies. METHODS: A combined model of the decision tree and Markov models was developed to compare expected costs, quality-adjusted life-years (QALYs) and incremental cost-effectiveness ratio (ICER) between screening and no screening groups. The model included liver disease-related health states and cardiovascular disease (CVD) states as a base-case analysis. Screening strategy consisted of fibrosis-4 index (FIB-4) followed by vibration-controlled transient elastography (VCTE) and intensive lifestyle intervention (ILI) as a treatment for diagnosed patients. RESULTS: Cost-effectiveness analysis showed that screening the at-risk population entailed $298 incremental costs and an additional 0.0199 QALY per patient compared to no screening (ICER $14 949/QALY). Screening was cost-effective based on the implicit ICER threshold of $25 000/QALY in Korea. When the effects of ILI on CVD and extrahepatic malignancy were incorporated into the cost-effectiveness model, the ICER decreased by 0.85 times from the base-case analysis (ICER $12 749/QALY). In contrast, when only the effects of liver disease were considered in the model, excluding cardiovascular disease effects, ICER increased from the baseline case analysis to $16 305. Even when replacing with medical costs in Japan and U.S., it remained cost-effective with the estimate below the countries' ICER threshold. CONCLUSIONS: Our study provides compelling evidence supporting the cost-effectiveness of FIB-4-based screening the at-risk population for advanced hepatic fibrosis.

Systematic Hospital-Based Travel Screening to Assess Exposure to Zika Virus1.

We queried hospital patients about international travel in the previous 30 days to assess potential importation of emerging infections. We used 12 months of deidentified data to analyze patient demographics, travel destinations, and diagnoses for exposure to Zika virus. Our approach could be used to analyze potential infectious disease exposures.

Epidemiological characteristics associated with uptake of pneumococcal vaccine among older adults living in the community in Singapore: Results from the National Health Surveillance Survey 2013.

AIMS: In Singapore, pneumococcal vaccination is recommended for the elderly (i.e. those ≥65 years of age) and people with chronic medical conditions. We investigated epidemiological characteristics associated with the uptake of pneumococcal vaccine based on a nationally representative cross-sectional sample of community-living adults aged ≥50 years. METHODS: The data were obtained from the National Health Surveillance Survey (NHSS) 2013. Associations between pneumococcal vaccination and sociodemographic and health-related variables were analysed using univariable and multivariable logistic regression models. RESULTS: Among 3672 respondents aged ≥50 years in the NHSS, 7.8% had taken the pneumococcal vaccination. A higher level of education and higher monthly household income were sociodemographic characteristics independently associated with pneumococcal vaccine uptake. Health-related characteristics predictive of pneumococcal vaccine uptake were better self-rated health and having a regular family doctor/general practitioner. Among those who responded to the two questions on vaccinations, 3.9% had been vaccinated against both seasonal influenza and pneumococcal infection, while 11.1% had taken only seasonal influenza vaccination in the past year. CONCLUSIONS: There is a need to boost pneumococcal vaccination coverage among community-dwelling older adults. These findings provide insights into reviewing and tailoring public-health strategies and programmes to increase vaccine uptake in at-risk population groups.

Factors associated with influenza vaccine uptake in older adults living in the community in Singapore.

In Singapore, influenza vaccination is recommended for persons at higher risk of complications of seasonal influenza, including those with chronic medical conditions and the elderly (individuals aged ⩾65 years). We investigated the factors associated with influenza vaccine uptake based on a nationally representative sample of community-dwelling adults aged >50 years. The data for this study were obtained from the National Health Surveillance Survey (NHSS) 2013. The association between influenza vaccine uptake and socio-demographic and health-related variables was analysed using univariable and multivariable logistic regression models. Of 3700 respondents aged ⩾50 years in the NHSS, 15·2% had received seasonal influenza vaccination in the past year. Older age, single marital status and economic inactivity were the socio-demographic variables independently associated with vaccine uptake. Health-related factors which were predictive of influenza vaccine uptake were sufficient total physical activity, better self-rated health, having at least one medical condition at risk of influenza complications and a regular family doctor/general practitioner. Influenza vaccine uptake in community-dwelling older adults was low. Our findings are of relevance in the formulation of public health policies and targeted health promotion strategies to increase vaccine uptake in this population group.

Cost-Savings Analysis of the Better Beginnings, Better Futures Community-Based Project for Young Children and Their Families: A 10-Year Follow-up.

This study examined the long-term cost-savings of the Better Beginnings, Better Futures (BBBF) initiative, a community-based early intervention project for young children living in socioeconomically disadvantaged neighborhoods during their transition to primary school. A quasi-experimental, longitudinal two-group design was used to compare costs and outcomes for children and families in three BBBF project neighborhoods (n = 401) and two comparison neighborhoods (n = 225). A cost-savings analysis was conducted using all project costs for providing up to 4 years of BBBF programs when children were in junior kindergarten (JK) (4 years old) to grade 2 (8 years old). Data on 19 government service cost measures were collected from the longitudinal research sample from the time the youth were in JK through to grade 12 (18 years old), 10 years after ending project participation. The average family incremental net savings to government of providing the BBBF project was $6331 in 2014 Canadian dollars. When the BBBF monetary return to government as a ratio of savings to costs was calculated, for every dollar invested by the government, a return of $2.50 per family was saved. Findings from this study have important implications for government investments in early interventions focused on a successful transition to primary school as well as parenting programs and community development initiatives in support of children's development.

Child-mother attachments in the face of grandparent HIV.

Child-mother attachment, as observed in the Strange Situation (SSP), was assessed in 61 families affected by HIV and 18 neighborhood comparison families not affected by HIV, but of similar ethnicity and socioeconomic status. Children were aged one to three years at the assessment. Secure attachment was significantly less likely among children in the HIV-affected group than among comparison group children (36% versus 67%). The most common pattern of attachment in the HIV-affected group was disorganized/disoriented, observed in 41% of children (versus 22% of comparison children). Children from families that included a surviving grandparent with HIV showed disorganized attachments more often than children whose grandparents died (53% versus 36%). Child attachment classifications were not associated with families' participation in a family-based, cognitive-behavioral HIV intervention. These results document the inter-generational impact of young mothers' who were growing up with an HIV-infected parent. These findings suggest that families affected by HIV may benefit from interventions that address attachment issues.

Comparative evaluation of non-invasive tests for risk stratification for cause specific mortality in at-risk population of hepatic fibrosis.

Our study aimed to conduct a comparative evaluation of various noninvasive tests (NITs) for risk stratification in at-risk population for non-alcoholic fatty liver disease (NAFLD), focusing on cardiovascular and liver-related mortality. A total of 21,715 adults aged 40 years and older were enrolled at baseline. The mean follow-up period was 12.39 years. Three types of NITs (fibrosis-4 index [FIB-4], NAFLD fibrosis score [NFS], and steatosis-associated fibrosis estimator [SAFE] score) were used. When using the low cut-off as a 'rule-out' strategy, there were no significant differences in cardiovascular mortality between the 'rule-out' (low-risk) group and the 'rule-in' (intermediate- or high-risk) group based on FIB-4 (aHR = 1.029, P = 0.845) or NFS (aHR = 0.839, P = 0.271) classification. However, the SAFE score exhibited higher sensitivity in predicting cardiovascular mortality compared to FIB-4 or NFS (73.3% in SAFE score vs. 29.6% in FIB-4 or 21.3% in NFS). Only the SAFE score could effectively differentiate the risk between low- and intermediate- or high-risk groups for all types of mortality (all P values for aHR < 0.001). The low cutoff value of the SAFE score discriminated not only liver-related mortality but also identified the cardiovascular high-risk group in the community cohort.

Exploring protective factors in a high-risk subsample: the pivotal role of paternal support in preventing depression in a cohort of young adults.

BACKGROUND: Major depressive disorder (MDD) is a global concern due to its widespread prevalence and morbidity. Identifying protective factors in high-risk individuals, including those with a familial predisposition, maltreatment history, and socio-economic vulnerabilities, is crucial. METHODS: We assessed a high-risk subsample within a young adult population cohort (n = 791; mean age = 31.94 [SD = 2.18]) across three waves. Using multiple regression models to analyse higher education, feeling supported, spirituality, psychotherapy access, higher socioeconomic status, involvement in activities, cohabitation, and family unity in Waves 1 and 2, and their association with MDD resilience at Wave 3. RESULTS: In the high-risk group, MDD incidence was 13.7% (n=24). Paternal support had a protective effect on MDD incidence (OR = 0.366; 95% CI [0.137 to 0.955], p = 0.040) and suicidal attempt risk (OR = 0.380; 95% CI [0.150 to 0.956], p = 0.038). Higher resilience scores were also protective (OR = 0.975; 95% CI [0.953 to 0.997], p = 0.030), correlating with reduced BDI (r = 0.0484; B = -0.2202; 95% CI [-0.3572 to -0.0738]; p = 0.003) and MADRS scores (r = 0.0485; B = -0.2204; 95% CI [-0.3574 to -0.0741]; p = 0.003). CONCLUSIONS: Our paper emphasizes reorienting the MDD approach, focusing on positive prevention strategies. It highlights fathers' crucial role in family-based interventions and promoting resilience in high-risk populations.

Alarming patterns of moderate and high-risk alcohol use among transgender women in Goiás, Central Brazil.

Background: Scant studies have examined alcohol consumption among transgender women in Latin America. This cross-sectional study estimated the prevalence and associated factors of risky alcohol use among transgender women in Goiás, a state located in the center of Brazil. Methods: Participants were 440 transgender women (median age = 35 years, interquartile range = 9) recruited through respondent-driven sampling. All participants were interviewed about sociodemographic characteristics, violence, and risk behavior. Alcohol use was assessed using the alcohol use disorders identification test (AUDIT). An AUDIT score greater than or equal to eight was considered as risky alcohol consumption. Logistic regression analysis was used to examine predictors of risky alcohol use, and p-values <0.05 were considered significant. Results: The majority were young, single, sex workers. Most transgender women had used alcohol in the previous year (85.7%), and more than half (56.6%) reported binge drinking and risky alcohol consumption (60.2%). There was a high overlap between sexual behavior, drugs, and alcohol use. Using alcohol during sex (adjusted odds ratio [aOR]: 2.9; 95% confidence interval [CI]: 1.7-4.8), cocaine/crack use (aOR: 2.3; 95% CI: 1.5-3.7) and having a drug user as a sexual partner (aOR: 2.9; 95% CI: 1.5-5.9) were independently associated with risky alcohol consumption. Conclusion: Alcohol consumption was highly prevalent, and drugs seem to play an important role in risky alcohol consumption among transgender women Goiás. These findings support stakeholders to promote intervention strategies to reduce this pattern of alcohol consumption and reduce the burden of substance use disorders among transgender women.

Clinical Classification, Screening, and Diagnosis in Beta-Thalassemia and Hemoglobin E/Beta-Thalassemia.

This article reviews the classification of beta-thalassemia syndromes, correlating clinical severity and genotype in the earlier classification, and broadening it recently based on clinical severity and transfusion status. The classification is dynamic, and individuals may progress from transfusion-independent to transfusion-dependent. Early and accurate diagnosis prevents delays in instituting treatment and comprehensive care, and precludes inappropriate and potentially harmful interventions. Screening can inform risk in an individual and subsequent generations when partners may be carriers as well. This article discusses the rationale for screening of the at-risk population. In the developed world, a more precise genetic diagnosis must be considered.

Heightened Sexual Misconduct Victimization Rates among Reserve Officers' Training Corps Women: Results From a Campus Climate Survey.

Sexual assault, harassment, and stalking are commonplace among college students, with identified subgroups being particularly at risk (e.g., Greek-life organizations and intercollegiate athletics). Despite higher rates of sexual misconduct among active-duty military and service academy women, no research has examined the risk for Reserve Officers' Training Corps (ROTC) women. A total of N = 1,562 college women were sampled from a sexual misconduct campus climate survey. ROTC women reported higher victimization rates for all variants of sexual misconduct and violence relative to the broader student population, as well as previously established high-risk groups. Directions for future research and implications for prevention programming/response are presented and discussed.

Burden of vaccine-preventable diseases among at-risk adult populations in the US.

Life-course immunization holds significant benefit for population health by reducing the burden of vaccine-preventable diseases (VPD) through vaccinating individuals at different stages and circumstances in life. The study aimed to determine the epidemiologic, clinical, economic, and societal burden of VPDs among at-risk adult subpopulations in the United States. A systematic literature review was conducted for articles published between January 2010 and June 2020, which identified 72 publications. There was heterogeneity in available epidemiology data, with the prevalence of VPDs ranging from 1.1% to 68.7%. Where the disease burden was described, outcomes were typically worse among high-risk subpopulations than in the general population. Several VPDs, including herpes zoster, meningococcal, and pneumococcal infections were associated with increased costs. This review suggests that subpopulations may not frequently interact with the healthcare system, or their risk factors may not be recognized by healthcare providers, and therefore individuals may not be appropriately targeted for vaccination.

Vaccine uptake and barriers to vaccination among at-risk adult populations in the US.

To reduce morbidity and mortality associated with vaccine-preventable diseases (VPD), it is imperative that vaccination programs are implemented and prioritized throughout all stages of life across all populations. This study aimed to determine vaccine uptake and barriers to vaccination against VPDs among at-risk adult populations in the United States. We conducted a systematic literature review for articles published between January 2010 and June 2020 and identified 153 publications. The review identified 17 at-risk populations. Vaccine uptake was suboptimal among many populations, with factors including age, gender, and disease severity, associated with uptake. This review identified several barriers that impact vaccine uptake among at-risk populations, with concerns over safety, vaccine costs, lack of insurance, and lack of provider recommendation commonly reported across populations. Embracing a national life-course immunization framework that integrates developing policies, guidelines, and education would be a step to addressing these barriers.

Effects of Reading Interventions Implemented for Upper Elementary Struggling Readers: A Look at Recent Research.

In this study, we conducted a review of reading intervention research (1988-2019) for upper elementary struggling readers and examined intervention area (e.g., foundational, comprehension, or multicomponent) and intensity (e.g., hours of intervention, group size, and individualization) as possible moderators of effects. We located 33 studies containing 49 treatment-comparison contrasts, found small effects for foundational reading skills (g = 0.22) and comprehension (g = 0.21), and decreased effects when considering standardized measures only. For intervention area, only multicomponent interventions predicted significant effects for both comprehension and foundational outcomes. For intensity, we did not find systematic evidence that longer or individualized interventions were associated with larger effects. However, interventions implemented in very small groups predicted larger comprehension outcomes. Overall, more research examining the quality of school provided reading instruction and how the severity of reading difficulties may impact effects of more intensive interventions is needed.

Pig-hunting dogs are an at-risk population for canine heartworm (Dirofilaria immitis) infection in eastern Australia.

BACKGROUND: Canine heartworm disease, caused by Dirofilaria immitis, has global veterinary importance. In Australia, the prevalence of canine heartworm infection decreased markedly following the introduction of over-the-counter macrocyclic lactones. We aimed to estimate the prevalence of canine heartworm infection in at-risk populations of dogs in eastern Australia and analyse published prevalence data from Australia. METHODS: In total, 566 dogs from eastern Australia were tested for the presence of D. immitis antigen. Four cohorts were studied: pig-hunting dogs from Queensland (Cohort 1, n = 104), dogs from remote New South Wales (NSW) (Cohort 2, n = 332), urban pets from rural NSW (Cohort 3, n = 45) and ex-racing Greyhounds from Sydney, NSW (Cohort 4, n = 85). Serum samples were screened for D. immitis antigen using a reference laboratory microwell-based assay (DiroChek®) or a point-of-care immunochromatography test kit (Anigen Rapid®). Risk factors associated with the odds of D. immitis antigen seropositivity were identified using binary logistic regression models. Seropositive blood samples were tested for the presence and quantity of D. immitis DNA using a species specific real-time (q)PCR assay. A metanalysis of the Australian canine heartworm literature was conducted. RESULTS: The prevalence of dirofilariasis in pig-hunting dogs from Queensland (Cohort 1) was 12.5% (95% CI: 6.5-18.9%), with a subpopulation of dogs from Central Queensland having a prevalence of 21% (95% CI: 12.3-33.4%). Age was significantly associated with D. immitis antigen seropositivity (increased risk with increased age). The odds of being > 5 years versus ≤ 5 years was 3.7-times (95% CI: 1.1-12.5) greater in antigen positive versus antigen negative dogs. No D. immitis antigen positive dogs were detected in dogs from NSW (Cohorts 2-4). The Australian canine heartworm disease literature includes 98 peer-reviewed publications (1901-2019) with 30 studies reporting on D. immitis prevalence in dogs. Throughout the publication peak period (1980s), the primary antemortem diagnostic test was detection of microfilariae. CONCLUSIONS: Canine heartworm infection in dogs used for pig hunting is a previously unexplored topic in Australia. Pig-hunting dogs are infected with canine heartworm in Queensland, Australia, placing pet dogs and cats at increased risk of infection.

Blended care in the treatment of subthreshold symptoms of depression and psychosis in emerging adults: A randomised controlled trial of Acceptance and Commitment Therapy in Daily-Life (ACT-DL).

In this study, the feasibility and efficacy of Acceptance and Commitment Therapy in Daily Life (ACT-DL), ACT augmented with a daily life application, was investigated in 55 emerging adults (age 16 to 25) with subthreshold depressive and/or psychotic complaints. Participants were randomized to ACT-DL (n = 27) or to active control (n = 28), with assessments completed at pre- and post-measurement and 6- and 12-months follow-up. It took up to five (ACT-DL) and 11 (control) months to start group-based interventions. Participants attended on average 4.32 out of 5 ACT-DL sessions. On the app, they filled in on average 69 (48%) of signal-contingent beep-questionnaires, agreed to 15 (41%) of offered beep-exercises, initiated 19 on-demand exercises, and rated ACT-DL metaphors moderately useful. Relative to active control, interviewer-rated depression scores decreased significantly in ACT-DL participants (p = .027). Decreases in self-reported depression, psychotic-related distress, anxiety, and general psychopathology did not differ between conditions. ACT-DL participants reported increased mean NA (p = .011), relative to active controls. Mean PA did not change in either group, nor did psychological flexibility. ACT-DL is a feasible intervention, although adaptations in future research may improve delivery of and compliance with the intervention. There were mixed findings for its efficacy in reducing subthreshold psychopathology in emerging adults. Dutch Trial Register no.: NTR3808.

Probiotic supplements might not be universally-effective and safe: A review.

Last few decades have witnessed the unprecedented growth in the application of probiotics for promoting the general gut health as well as their inception as biotherapeutics to alleviate certain clinical disorders related to dysbiosis. While numerous studies have substantiated the health-restoring potentials for a restricted group of microbial species, the marketed extrapolation of a similar probiotic label to a large number of partially characterized microbial formulations seems biased. In particular, the individuals under neonatal stages and/or those with some clinical conditions including malignancies, leaky gut, diabetes mellitus, and post-organ transplant convalescence likely fail to reap the benefits of probiotics. Further exacerbating the conditions, some probiotic strains might take advantage of the weak immunity in these vulnerable groups and turn into opportunistic pathogens engendering life-threatening pneumonia, endocarditis, and sepsis. Moreover, the unregulated and rampant use of probiotics potentially carry the risk of plasmid-mediated antibiotic resistance transfer to the gut infectious pathogens. In this review, we discuss the safety perspectives of probiotics and their therapeutic interventions in certain at-risk population groups. The embodied arguments and hypotheses certainly will shed light on the fact why probiotic usage should be treated with caution.

Nutrition Environment Food Pantry Assessment Tool (NEFPAT): Development and Evaluation.

OBJECTIVE: To develop and evaluate a nutrition environment assessment tool to assess the consumer nutrition environment and use of recommended practices in food pantries. METHODS: The Nutrition Environment Food Pantry Assessment Tool (NEFPAT) was developed based on a literature review and guidance from professionals working with food pantries. The tool was pilot-tested at 9 food pantries, an expert panel assessed content validity, and interrater reliability was evaluated by pairs in 3 pantries. After revisions, the NEFPAT was used in 27 pantries. RESULTS: Pilot tests indicated positive appraisal for the NEFPAT and recommendations were addressed. The NEFPAT's 6 objectives and the overall tool were rated as content valid by experts, with an average section rating of 3.85 ± 0.10. Intraclass correlation coefficients for interrater reliability were >0.90. CONCLUSIONS AND IMPLICATIONS: The NEFPAT is content valid with high interrater reliability. It provides baseline data that could be valuable for interventions within the nutrition environment of food pantries.

Emerging Adulthood: A Time of Changes in Psychosocial Well-Being.

The principal aim of this study was to investigate the psychosocial well-being of emerging adults using psychological states associated with this transitional phase and classic measures of emerging adulthood. We expected psychological states to be more closely associated with psychological well-being than classic markers of achieved adulthood. Data were collected in the Cohort Study on Substance Use Risk Factors from 4,991 Swiss men aged 18-25 years. The assessment included the Short Form of the Inventory of Dimensions of Emerging Adulthood (IDEA-8), classic markers of achieved adulthood (e.g., financial independence, stable relationship), and psychosocial well-being. Structural equation models (SEMs) were conducted to test the association between measures of emerging adulthood and psychosocial well-being. Overall, the results highlighted contrasting associations of measures of emerging adulthood and psychosocial well-being. Youths facing negative psychological states (dimension "negativity") and exploring life without knowing how to define themselves (dimension "identity exploration") had a decreased psychosocial well-being. On the contrary, youths exploring many opportunities with an optimistic perspective (dimension "experimentation") had an increased psychosocial well-being. By contrast, classic markers of adulthood were less related to psychosocial well-being. The IDEA-8 Scale appeared to be a useful screening tool for identifying vulnerable youths, and emerging adulthood should be measured with a focus on the psychological states associated with this period. This information may be valuable for mental health systems that have not yet adapted to emerging adults' needs.

Comparison of Models Analyzing a Small Number of Observed Meningitis Cases in Navrongo, Ghana.

The "meningitis belt" is a region in sub-Saharan Africa where annual outbreaks of meningitis occur, with epidemics observed cyclically. While we know that meningitis is heavily dependent on seasonal trends, the exact pathways for contracting the disease are not fully understood and warrant further investigation. Most previous approaches have used large sample inference to assess impacts of weather on meningitis rates. However, in the case of rare events, the validity of such assumptions is uncertain. This work examines the meningitis trends in the context of rare events, with the specific objective of quantifying the underlying seasonal patterns in meningitis rates. We compare three main classes of models: the Poisson generalized linear model, the Poisson generalized additive model, and a Bayesian hazard model extended to accommodate count data and a changing at-risk population. We compare the accuracy and robustness of the models through the bias, RMSE, and standard deviation of the estimators, and also provide a detailed case study of meningitis patterns for data collected in Navrongo, Ghana.
