Advancing Hepatitis C Elimination through Opt-Out Universal Screening and Treatment in Carceral Settings, United States.

Incarcerated persons are infected with hepatitis C virus (HCV) at rates ≈10 times higher than that of the general population in the United States. To achieve national hepatitis C elimination goals, the diagnosis and treatment of hepatitis C in incarcerated persons must be prioritized. In 2022, the Centers for Disease Control and Prevention recommended that all persons receive opt-out HCV screening upon entry into a carceral setting. We review recommendations, treatments, and policy strategies used to promote HCV opt-out universal HCV screening and treatment in incarcerated populations in the United States. Treatment of hepatitis C in carceral settings has increased but varies by jurisdiction and is not sufficient to achieve HCV elimination. Strengthening universal HCV screening and treatment of HCV-infected incarcerated persons is necessary for HCV elimination nationwide.

Real-world genetic testing outcomes of pan-cancer testing for mismatch repair deficiency.

BACKGROUND: In 2017, the Food and Drug Administration approved pembrolizumab for treatment of any mismatch repair-deficient (dMMR) tumor making MMR immunohistochemistry (IHC) testing beneficial for all tumor types. For the first time, MMR IHC was not performed exclusively to screen for Lynch syndrome (LS). METHODS: In this study, all MMR IHC reports issued between 2017 and 2021 at an academic hospital were reviewed and completion of genetic testing was determined through chart review. Colorectal cancers (CRCs), endometrial cancers (ECs), and noncancerous lesions were excluded. RESULTS: Between 2017 and 2021, MMR IHC was completed in 1939 patients with a malignancy other than CRC or EC. Absent or weak staining for at least one MMR protein was detected in 115 (5.9%) patients and 59 (51%) of those completed germline genetic testing. Overall, the identification rate of LS in this cohort was 0.72%, which is similar to the rate in our previously reported CRC and EC universal screening cohort. A diagnosis of LS was most commonly made in patients with dMMR brain (18.75%) and small intestinal cancers (10.20%). Five additional patients were found to carry a pathogenic variant in a non-LS gene. CONCLUSIONS: Pan-cancer MMR testing for pembrolizumab consideration can identify LS cases at a rate similar to universal CRC and EC screening programs. A persistent challenge is subsequent uptake of genetic testing. MMR testing should be prioritized in brain and small intestinal tumors, and multigene panel testing is recommended in patients with dMMR, as unexpected pathogenic variants in non-LS genes were found as frequently as LS gene variants.

Province-Wide Ascertainment of Lynch Syndrome in Manitoba.

BACKGROUND & AIMS: We describe the experience of Lynch syndrome (LS) diagnosis in the province of Manitoba, Canada, over the past 20 years. METHODS: We performed a retrospective review of charts from the provincial Genetics Clinic from January 1, 2000, to May 31, 2023. We extracted data on individuals identified to carry a germline pathogenic or likely pathogenic LS gene variant, the mode of ascertainment, family history, and cascade genetic testing (CGT). Data were stratified and compared before and after the year of implementation (October 2013) of the provincial LS screening program (LSSP) and ascertainment by the LSSP vs clinic referrals (CRs). RESULTS: Between 2014 and 2021, 50 of 101 (49.5%) index cases were identified by the LSSP compared with 51 of 101 (50.5%) from CRs. The proportion of PMS2 variants was 34% (17 of 50) for LSSP index cases compared with 21.6% (11 of 51) for CRs from 2014 to 2021 (P < .001). Among CRs from 2014 to 2021, 24 of 51 (47.1%) families met the Amsterdam criteria, compared with 11 of 50 (22.0%) for the LSSP (P = .01). CGT occurred among 46.8% (95 of 203; average, 1.9 relatives/index) of first-degree relatives of CR index cases vs 36.5% (84 of 230; average, 1.7 relatives/index) of first-degree relatives of LSSP index cases (P = .03). Daughters were most likely to undergo CGT. CONCLUSIONS: A tumor screening program is more effective at detecting individuals with lower penetrant gene variants and families who do not meet traditional family history-based criteria. Cascade genetic testing is higher among clinic referrals compared with the screening program. These findings suggest a complementary role of these 2 ascertainment methods for Lynch syndrome.

Influence of easing COVID-19 strategies following downgrading of the national infectious disease category on COVID-19 occurrence among hospitalized patients in Japan.

PURPOSE: We aimed to evaluate the influence of easing COVID-19 preventive measures following its downgrading to a common infectious disease on COVID-19 occurrence among hospitalized patients. METHODS: Nosocomial occurrence of COVID-19 was compared between periods with national infectious disease category 5 versus the preceding category 2 equivalent. Changes in the revised manual included a shorter duration of work restrictions for infected health care practitioners (HCPs); no work restriction for HCPs exposed to SARS-CoV-2 with a negative test on days 1, 3 and 5; discontinuation of universal pre-admission screening; and pre-emptive isolation of patients without screening. Wearing an N95 mask and face shield was required in procedure/care with moderate-to high-risk contact. RESULTS: Although the mean monthly number of infected HCPs increased from 8.1 to 12.7 in the category 5 period (p = 0.034) and that of pre-admission screening decreased to one-fourth, the COVID-19 incidence in hospitalized patients remained similar between the two study periods (1.60 ± 5.59/month versus 1.40 ± 2.63/month, p = 0.358). Clusters, defined as ≥3 COVID-19 patients on the ward, were experienced twice in the preceding period and only once in the category 5 period. The index cases causing nosocomial SARS-CoV-2 transmission mostly involved rehabilitation therapists in the preceding period; five of six index cases were patients in the category 5 period. Following the expanded indication for N95 masks, neither SARS-CoV-2 transmission to patients nor transmission from infected patients was observed in HCPs for 1 year. CONCLUSION: With sustained, enhanced standard precautions, easing prevention strategies could limit nosocomial SARS-CoV-2 infections.

SARS-CoV-2 RT-PCR as a universal screening on planned admission in asymptomatic patients.

Universal screening for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) on admission is reportedly beneficial in preventing nosocomial infections. However, some issues remain, including low positivity rate, cost, and time required for testing. We describe SARS-CoV-2 reverse transcription polymerase chain reaction (PCR) for universal screening in asymptomatic patients on planned admissions. In total, 14,574 patients were included between October 12, 2020, and June 23, 2022. The PCR-positive rate for the period was 0.44 % (64/14,574). The PCR positivity for the epidemic period by strain was 0.28 % (95 % confidence interval [CI] 0.12-0.56 %), 0.16 % (95 % CI 0.05-0.37 %), 0.21 % (95 % CI 0.09-0.41 %), and 0.9 % (95 % CI 0.65-1.2 %) for the wild-type strain, Alpha, Delta, and Omicron variants, respectively. The proportion of Ct values < 30 was higher in the first half of the epidemic (first vs. second, 29.4 % [95 % CI 16.9-44.8 %] vs. 16.7 % [95 % CI 6.0-28.5 %]), whereas that of Ct values ≥ 35 increased significantly in the second half (first vs. second, 32.4 % [95 % CI 19.3-47.8 %] vs. 70.0 % [95 % CI 53.5-83.4 %]). Of all positives, 50 % (32/64) had a coronavirus disease (COVID-19) history before PCR screening, with a median of 28 days (10-105) from COVID-19 onset or positive to PCR screening. PCR screening may help detect positives with high viral loads early in the epidemic for each mutant strain, with an increasing proportion of positives with low viral loads later in the epidemic. PCR testing may be unnecessary for recently diagnosed cases and patients in whom reinfection is unlikely.

Universal Child Mental Health Screening for Parents: a Systematic Review of the Evidence.

Childhood represents a critical window for the emergence and treatment of mental health disorders, yet many are not being identified, or are identified too late to receive adequate intervention. This systematic review (Prospero registration: CRD42022299560) aimed to determine the effectiveness and acceptability of parent reported universal mental health screening (UMHS) to improve the early identification of children at-risk of mental health difficulties, and to identify barriers and enablers that may influence parental engagement. Six databases were searched in February 2022 for peer-reviewed, primary research. Studies conducted in targeted populations, evaluating psychometric properties, or focused on screening non-psychological problems were excluded. Ten studies examined parent reported (n = 3,464 parents) UMHS for children from birth to 18 years, suggesting an overall scarcity of research. Findings are presented in a table of study characteristics and a narrative summary of acceptability, effectiveness, barriers, and enablers. Quantitative findings indicated that parents generally support and accept UMHS. Research assessing effectiveness was limited, although two studies indicated increased referrals and referral adherence following positive screens. Confidentiality and stigma were commonly identified barriers. Quality assessment using the Mixed Methods Appraisal Tool indicated that studies varied in quality, meeting four to seven of the seven quality criteria. Understanding and addressing parent attitudes to UMHS across settings is necessary for the successful implementation of screening and improvement of child mental health outcomes. More high-quality research studies, including randomized controlled trials are therefore needed to examine the acceptability and effectiveness of UMHS for parents and their children.

The Brief Evaluation of Adolescents and Children Online (BEACON): Psychometric development of a mental health screening measure for school students.

This paper describes the development and psychometric evaluation of a brief self-report measure (BEACON) to inform universal mental health screening in schools. Items assess symptoms and impairment associated with anxiety and attention/hyperactivity problems (grades 4-11) as well as depression and eating difficulties (grades 6-11), with optional items for suicidality and self-harm (grades 7-11). Initial item examination based on Item Response Theory (IRT) and classical test theory involved 3844 students in grades 4 through 11 (Study 1) and identified 18 items for grades 4-5 and 31 items for grades 6-11 that fulfilled pre-set criteria. Study 2 extended testing with 10,479 students in grades 4-11 and added an additional four items assessing impairment associated with eating difficulties for older students (grades 6-11) creating a total of 35 items for grades 6-11. All items, for both grade-level versions, met the pre-set criteria for IRT and classical test theory analysis supporting their strength in the measurement of the dimensions of concern. The measure showed good reliability (subscale alphas .87 to .95). Validity was also demonstrated against standard symptom measures, school grades, school absenteeism, and help-seeking. The BEACON appears to be a psychometrically sound measure to use in the first stage of school-based screening for mental health problems.

Preoperative MRSA screening using a simple questionnaire prior elective total joint replacement.

INTRODUCTION: The purpose of this study was to evaluate the management and results of our standarized protocol for preoperative identification of MRSA colonisation in patients undergoing primary total hip and knee replacement procedures. METHODS: Following hospital protocol, between January 2016 and June 2019 37,745 patients awaiting elective joint replacement underwent a standardized questionnaire to assess the risk of MRSA infection, identifying patients requiring preoperative MRSA screening. An evaluation of the questionnaire identified effective questions for identifying infected patients. Furthermore, an analysis evaluated the impact of comorbidities or Charlson Comorbidity Index scores on positive MRSA colonization. Additionally, we evaluated the cost savings of targeted testing compared to testing all surgery patients. RESULTS: Of the 37,745 patients, 8.057 (21.3%) were swabbed, with a total of 65 (0.81%) positive tests. From this group 27 (36.48%) who were treated were negative before surgery. Some of the questionnaire results were consistently associated with a higher chance of colonization, including hospitalization during the past year (47,7%), previous history of MRSA (44,6%), and agriculture or cattle farming related work (15,4%). By selectively testing high-risk patients identified through the questionnaire, we achieved a 79% reduction in costs compared to universal MRSA screening. CONCLUSION: Our results suggest that the simple and standardized questionnaire is a valuable tool for preoperative screening, effectively identifying high-risk patients prone to MRSA colonisation. The risk of periprosthetic joint infection (PJI) and its associated sequelae may be reduced by this approach.

Universal Suicidality Screening in a Pediatric Emergency Department to Improve Mental Health Safety Risk.

INTRODUCTION: Suicide is the second leading cause of death for youth 12 to 18 years of age. Suicidal ideation can be predictive of suicide attempt, so screening for suicidal ideation by emergency nurses can help identify those at risk and facilitate timely intervention. This study evaluates the use of a universal suicide screening using the Patient Safety Screener 3 and the Columbia Suicide Severity Rating Scale to identify youth ages 12 to 18 years experiencing suicide risk and assess factors predictive of suicide risk level. METHODS: We conducted a retrospective cohort study using data from patients presenting to the emergency department at an acute care hospital that uses a universal screening program for suicide risk. We determined the frequency of positive screens and performed multivariate analyses to identify predictive factors of scoring high on the Columbia Suicide Severity Rating Scale. RESULTS: Notably, 9.1% of patients were experiencing some level of suicide risk; 10% of those with positive scores had no mental health history and were not presenting for a mental health reason. After controlling for other independent variables, insurance status, mental health presentation, and known mental health history were significantly associated with Columbia Suicide Severity Rating Scale score. DISCUSSION: Universal screening for suicide risk in pediatric emergency departments by nurses is critical for all patients older than 12 years, given that we identified patients at risk of suicide who presented for non-mental health reasons. These patients may not have been identified or referred to treatment if they were not screened for suicidality increasing risk of future suicide attempt.

Validation of the Electronic Modified Checklist for Autism in Toddlers, Revised with Follow-Up: A Nonrandomized Controlled Trial.

OBJECTIVE: To examine the classification rates and screening properties, including sensitivity and specificity, of the web-based Modified Checklist for Autism in Toddler, Revised with Follow-Up (M-CHAT-R/F) compared with paper-phone administration, and to determine the extent to which electronic M-CHAT-R/F streamlines screening, increases screening fidelity, increases diagnostic evaluation participation, and decreases waiting time from screening to evaluation compared with paper-phone modality. STUDY DESIGN: Primary-care practices in urban and suburban settings administered either the web-based or paper-phone M-CHAT-R/F using a prospective nonrandomized control design. Toddlers (n = 17 900) were screened between 2009 and 2016 at routine well-child check-ups. Toddlers who screened at risk on the M-CHAT-R/F were invited to complete diagnostic evaluations; 176 children were diagnosed with autism. The χ2, Fisher exact, and t-tests, as well as regression and screening properties, were used to compare outcome distributions, screening properties, and implementation by modality. RESULTS: Classification rates of the initial M-CHAT-R into low, medium, and high risk were significantly different across modalities with very small effect sizes. Sensitivity and specificity were high across both modalities. For children in the medium-risk range, the web-based modality had a greater rate of predicting risk for autism after Follow-Up compared with the paper-phone modality, and the web eliminated delay between initial screen and Follow-Up. The web-based modality showed increased screening fidelity, no data loss, and similar rates of evaluation attendance and time to evaluation from Follow-Up administration. CONCLUSIONS: The web-based M-CHAT-R/F is a valid tool for universal autism screening. Systems-level decisions should balance the increased feasibility of the electronic administration with the increase in Follow-Up accuracy provided by skilled clinician interview.

Prevalence and characteristics of patients with upper urinary tract urothelial carcinoma having potential Lynch syndrome identified by immunohistochemical universal screening and Amsterdam criteria II.

BACKGROUND: This study aimed to identify patients with upper urinary tract urothelial carcinoma (UTUC) having potential Lynch syndrome (pLS) by immunohistochemistry (IHC) of DNA mismatch repair gene-related proteins (MMRPs) and Amsterdam criteria II and explore their clinical characteristics. METHODS: We retrospectively collected the clinical data of 150 consecutive patients with UTUC who underwent surgical resection at our institution between February 2012 and December 2020, and immunohistochemistry (IHC) of four MMRPs (MLH1, MSH2, MSH6, and PMS2) on all UTUC specimens was performed. Patients who tested positive for Amsterdam criteria (AMS) II and/or IHC screening were classified as having pLS and others as non-pLS, and their characteristics were explored. RESULTS: In this study, 5 (3%) and 6 (4%) patients were positive for AMS II and IHC screening, respectively. Two patient were positive for both AMS II and IHC screening, resulting in 9 (6%) patients with pLS. The pLS group was predominantly female (67% vs. 36%; p = 0.0093) and had more right-sided tumors (100% vs. 43%; p = 0.0009) than the non-pLS group. Of the 6 patients who were positive for IHC screening, 4 showed a combined loss of MSH2/MSH6 (n = 3) and MLH1/PMS2 (n = 1). Other two patients showed single loss of MSH6 and PSM2. CONCLUSIONS: AMS II and IHC screening identified pLS in 6% of patients with UTUC. The IHC screening-positive group tends to have relatively high rate of combined loss, but some patients have single loss. AMS II may overlook patients with LS, and a universal screening may be required for patients with UTUC as well as those with colorectal and endometrial cancer.

Routine screening of emergency admissions at risk of chronic hepatitis (SEARCH) identifies and links hepatitis B cases to care.

BACKGROUND AND AIMS: Significant barriers exist with hepatitis B (HBV) case detection and effective linkage to care (LTC). The emergency department (ED) is a unique healthcare interaction where hepatitis screening and LTC could be achieved. We examined the efficacy and utility of automated ED HBV screening for Overseas Born (OB) patients. METHODS: A novel-automated hepatitis screening service "SEARCH" (Screening Emergency Admissions at Risk of Chronic Hepatitis) was piloted at a metropolitan hospital. A retrospective and comparative analysis of hepatitis testing during the SEARCH pilot compared to a period of routine testing was conducted. RESULTS: During the SEARCH pilot, 4778 OB patients were tested for HBV (86% of eligible patient presentations), compared with 1.9% of eligible patients during a control period of clinician-initiated testing. SEARCH detected 108 (2.3%) hepatitis B surface antigen positive patients including 20 (19%) in whom the diagnosis was new. Among 88 patients with known HBV, 57% were receiving medical care, 33% had become lost to follow-up and 10% had never received HBV care. Overall, 30/88 (34%) patients with known HBV were receiving complete guideline-based care prior to re-engagement via SEARCH. Following SEARCH, LTC was successful achieved in 48/58 (83%) unlinked patients and 19 patients were commenced on anti-viral therapy. New diagnoses of cirrhosis and hepatocellular carcinoma were made in five and one patient(s) respectively. CONCLUSIONS: Automated ED screening of OB patients is effective in HBV diagnosis, re-diagnosis and LTC. Prior to SEARCH, the majority of patients were not receiving guideline-based care.

Reduction in cervical length after vaginal progesterone in women with short cervix is significantly associated with preterm delivery at ≤ 34 weeks and < 37 weeks of gestation.

OBJECTIVE: To evaluate the association between changes in cervical length (CL) after vaginal progesterone treatment and preterm delivery (PTD). METHODS: This was a retrospective cohort study that included 197 singleton pregnancies without (n = 178) and with (n = 19) a history of PTD which were found to have a short cervix (≤ 25 mm) between 18 + 0 and 23 + 6 weeks' gestation with a follow-up transvaginal CL measurement taken at least 1 week after vaginal progesterone treatment started. Receiver-operating-characteristics (ROC)-curve analysis was performed and three CL shortening patterns were evaluated: (1) ≥ 10% reduction; (2) ≥ 20% reduction; and (3) ≥ 5 mm reduction relative to the first CL measurement. The predictive performance of each CL reduction cut-off and its association with PTD ≤ 34 weeks and PTD < 37 weeks were evaluated. RESULTS: Overall, the rate of PTD ≤ 34 weeks was 16.8% (33/197) and that of PTD < 37 weeks was 36.5% (72/197). The area under the ROC curve of cervical shortening expressed in % for predicting PTD ≤ 34 weeks and PTD < 37 weeks was 0.703 and 0.608, respectively. Cervical shortening was observed in 60/197 (30.5%) patients, with 49/60 (81.7%) women showing ≥ 10% reduction, 32/60 (53.3%) ≥ 20% reduction and 27/60 (45.0%) ≥ 5 mm reduction in CL. Sensitivity and specificity for PTD ≤ 34 weeks were, respectively, 48.5% and 79.9% for ≥ 10% reduction; 36.4% and 87.8% for ≥ 20% reduction; and 27.3% and 89.0% for ≥ 5 mm reduction in CL. For PTD < 37 weeks, sensitivity and specificity were, respectively, 36.1% and 81.6% for ≥ 10% reduction; 27.8% and 90.4% for ≥ 20% reduction; and 20.8% and 90.4% for ≥ 5 mm reduction in CL. The highest positive likelihood ratios for PTD ≤ 34 and < 37 weeks were for ≥ 20% CL reduction (2.98 (95% CI, 1.62-5.49) and 2.89 (95% CI, 1.52-5.57), respectively). Despite significant differences in sensitivity among the different cut-offs for cervical shortening, favoring the ≥ 10% reduction cut-off, a reduction of ≥ 20% in CL showed the strongest association with PTD ≤ 34 weeks (odds ratio (OR), 4.11 (95% CI, 1.75-9.62)) and < 37 weeks (OR, 3.62 (95% CI, 1.65-7.96)), as compared with a less pronounced reduction in CL. CONCLUSIONS: In women with a short cervix treated with vaginal progesterone, a reduction in CL on a subsequent ultrasound scan can predict PTD ≤ 34 and < 37 weeks. A ≥ 20% reduction in CL had the highest positive likelihood ratio and association with PTD ≤ 34 and < 37 weeks compared with ≥ 10% or ≥ 5 mm reduction. © 2023 International Society of Ultrasound in Obstetrics and Gynecology.

Preferences and experiences of pediatricians on implementing national guidelines on universal routine screening of adolescents for major depressive disorder: A qualitative study.

BACKGROUND: To explore the preferences of pediatricians for key factors around the implementation of universal routine screening guidelines for major depressive disorder in adolescent patients in a primary care setting. METHOD: Semi-structured qualitative interviews were conducted with U.S. pediatricians. Participants were recruited by convenience sampling and snowball sampling. Qualitive data were summarized using thematic analysis to identify themes relevant to preferences around implementing screening strategies for adolescent patients. Recruitment ended upon reaching thematic saturation when no new themes were revealed. RESULTS: Of the 14 participants, 11 identified as female, 3 male, 10 white, and 4 Asian. Top themes among pediatrician participants were around the screening modality (14/14 participants), screening validity (14/14), time barriers (14/14), and confidentiality barriers (12/14). Less frequently mentioned themes by pediatricians were workplace coordination and logistics (7/14), alternative starting ages for screening (7/14), more frequent screenings than annual screenings (3/14), and additional clinical training regarding depression diagnosis and treatment (2/14). LIMITATIONS: Pool of interviewed participants was limited by diversity in terms of geography, race/ethnicity, or practice settings. CONCLUSIONS: To promote the uptake of universal routine screening of adolescent major depression, pediatricians expressed it was important to address key implementation factors regarding the screening modality, screening validity, time constraints, and confidential care concerns in a primary care delivery context. Findings could be used to inform the development of implementation strategies to facilitate depression screening in primary care. Future research is needed to quantitively assess decisions and tradeoffs that pediatricians make when implementing universal screening to support adolescent mental health.

Early Insights into Implementation of Universal Screening, Brief Intervention, and Referral to Treatment for Perinatal Substance Use.

OBJECTIVES: Perinatal substance use is a growing concern across the United States. Universal screening, brief intervention, and referral to treatment (SBIRT) is one systems-level approach to addressing perinatal substance use. The objective of this study is to assess early efforts to implement SBIRT in an outpatient obstetric clinic. METHODS: The research team implemented universal screening with the 5 P's screening tool. Providers then engaged patients in a brief intervention and referred to a care manager who then worked with patients via tele-health to connect patients with needed services. Feasibility was measured through the collection of aggregate data describing frequency of universal screening and referral to treatment. The implementation team met bi-weekly to reflect on implementation barriers and facilitators. RESULTS: In the first year of implementation, 48.5% of patients receiving care in the clinic completed the 5 P's screener at least once during the perinatal period. Screening occurred in a little over a quarter (26.5%) of eligible visits. Of the 463 patients that completed the 5 P's at least once during the perinatal period, 195 (42%) unique patients screened positive (answered yes to at least one question). CONCLUSIONS FOR PRACTICE: Early implementation efforts suggest this approach is feasible in this obstetric setting. Similar implementation studies should consider implementing universal screening for substance use and perinatal mood and anxiety disorders simultaneously; guide efforts using an implementation framework; invest resources in more intensive training and ongoing coaching for providers; and adopt strategies to track frequency and fidelity of brief intervention.

Parental Attitudes and Ideas Regarding Newborn Screening for Familial Hypercholesterolemia.

BACKGROUND: Familial hypercholesterolemia (FH) is an inherited disease which causes premature atherosclerotic cardiovascular disease. However, less than 10% of individuals with FH have been identified. OBJECTIVE: To assess parental perspectives for inclusion of FH on routine newborn screening (NBS) and to highlight potential benefits, harms, and ethical concerns. METHODS: Telephone interviews of two groups were conducted: 1) parents of children diagnosed with FH, and 2) parents of children diagnosed with a genetic condition through NBS. Stratified purposive sampling was used to ensure adequate representation. The 11 telephone interviews were conducted in 30-min sessions guided by a semi-structured interview script. At the beginning of the interview, participants were educated on the NBS process and FH. The interviews were transcribed verbatim, and a thematic analysis was performed in multiple steps. RESULTS: All interviewees indicated that they would be interested in having their child be screened for FH on the newborn screen. Reasons supporting screening during the newborn period included knowing their child's diagnosis, the ability to screen family members for FH, incorporation of lifestyle changes, and access to preventive care. Negatives surrounding screening during the newborn period included increased stress or anxiety, knowledge, stigma, and the delay from diagnosis to initiation of pharmacotherapy for FH. CONCLUSION: While these interviewees were in favor of NBS for FH, further education of parents and clinicians is needed to ensure proper implementation. The results of this study may be useful to formulate family notification and care protocols for newborns diagnosed with FH and other diseases.

What is already known on this subject? Familial hypercholesterolemia is a common inherited disorder that predisposes to early cardiovascular disease, but most affected individuals are not diagnosed. Childhood cholesterol screening is an effective but underutilized diagnostic tool. Previous studies report parents find childhood cholesterol screening acceptable, but it is not known if screening newborns would also be acceptable.What does this study add? Interviewees found screening newborns for familial hypercholesterolemia acceptable and would agree to screen their own newborn. The ability to screen other family members and access to early treatment were important factors in their decision to screen. Education of clinicians about familial hypercholesterolemia was an important concern raised by interviewees.

Using a multistep approach with multidisciplinary team to increase the diagnosis rate of Lynch syndrome-associated colorectal cancer after universal screening: a single-center study in Japan.

BACKGROUNDS: This study aimed to evaluate the changes in the rates of genetic counseling and genetic testing as well as the diagnosis rate of Lynch syndrome (LS)-associated colorectal cancer before and after multistep approach with multidisciplinary team in Japanese. METHODS: In September 2016, we started universal screening for LS by mismatch repair protein immunohistochemistry and prospectively collected the records. Following patient interviews, we started multistep approach with multidisciplinary team (MA) in January 2020. MA consists of six surgeons, one genetic counselor, one medical geneticist, and six pathologists. MA is set up to compensate for patients' lack of knowledge about genetic diseases and make case selection for elderly colorectal cancer patients with deficient mismatch repair (dMMR). MA is designed as a system that could be performed by a small number of medical genetic specialists. A total of 522 patients were included during the study duration, 323 and 199 patients in the pre-MA (P-MA) and MA groups, respectively. RESULTS: The frequency of dMMR in all patients was 10.0%. The patient interview results indicated a significant lack of patient education regarding genetic diseases. The rates of genetic counseling and genetic testing was significantly higher in MA group than in P-MA group (genetic counseling: MA 34.6% vs. P-MA 7.7%, p = 0.04; genetic testing: MA 30.8% vs. P-MA 3.8%, p = 0.02). Moreover, the diagnosis rate of LS-associated colorectal cancer was significantly higher in MA group (2.5%) than in P-MA group (0.3%) (P = 0.03). In addition, MA could be performed without problems despite the small number of medical and human genetics specialists. CONCLUSIONS: MA has achieved appropriate pickup of suspected hereditary colorectal cancer patients and complemented the lack of knowledge about genetic diseases. The introduction of MA increased LS-associated colorectal cancer after universal screening. MA is an appropriate LS screening protocol for Japanese patients who lag behind in medical and human genetics education.

Screening and Management of Lynch Syndrome: The Chinese Experience.

Lynch syndrome (LS), caused by germline mutations in the mismatch repair genes, is the most common hereditary colorectal cancer. While LS is also associated with various cancers, early detection of the proband is meaningful for tumor prevention, treatment, and familial management. It has been a dramatic shift on the screening approaches for LS. As the rapid development of the molecular biological methods, a comprehensive understanding of the LS screening strategies will help to improve the clinical care for this systematic disease. The current screening strategies have been well validated but mainly by evidence derived from western population, lacking consideration of the ethnic heterogeneity, which hampers the universality and clinical application in China. Hence, this review will focus on the Chinese experience in LS screening, aiming to help better understand the ethnic diversity and further optimize the screening strategies.

Cost-Effectiveness of 1-Time Universal Screening for Chronic Hepatitis B Infection in Adults in the United States.

BACKGROUND: An estimated 862 000 to 2.4 million people have chronic hepatitis B infection (CHB). Hepatitis B screening is recommended for pregnant women and populations with increased CHB risk. However, diagnosis rates remain low, with only 33% of people with CHB aware of their infection. This study aimed to assess the cost-effectiveness of universal adult screening for CHB. METHODS: We used a Markov model to calculate the costs, population health impact, and cost-effectiveness of 1-time universal screening and CHB monitoring and treatment compared with current practice. Sensitivity analysis was performed on model parameters to identify thresholds for cost-saving or cost-effectiveness based on a willingness to pay of $50 000/quality-adjusted life-year. The analysis assumed testing would be performed during routine healthcare visits and that generic tenofovir or entecavir would be dispensed for treatment. Testing costs were based on Medicare reimbursement rates. RESULTS: At an estimated 0.24% prevalence of undiagnosed CHB, universal hepatitis B surface antigen (HBsAg) screening in adults aged 18-69 years is cost-saving compared with current practice if antiviral treatment drug costs remain below $894/year. Compared with current practice, universal screening would avert an additional 7.4 cases of compensated cirrhosis, 3.3 cases of decompensated cirrhosis, 5.5 cases of hepatocellular carcinoma, 1.9 liver transplants, and 10.3 hepatitis B virus-related deaths at a saving of $263 000/100 000 adults screened. CONCLUSIONS: Universal HBsAg screening of adults in the US general population for CHB is cost-effective and likely cost-saving compared with current CHB screening recommendations.

Universal screening for familial hypercholesterolemia in 2 populations.

PURPOSE: In Europe, >2 million individuals with familial hypercholesterolemia (FH) are currently undiagnosed. Effective screening strategies for FH diagnosis in childhood are urgently needed. We assessed the overall performances of 2 different FH screening programs in children: universal screening program with opt-out and opt-in type participation. METHODS: We analyzed the data from 2 independent populations based on >166,000 individuals screened for hypercholesterolemia. Genetic analyses of FH-related genes were finalized in 945 children and 99 parents. RESULTS: A total of 305 (32.3%) children were genotyped as positive or with a variant of uncertain significance in FH-related genes. For low-density lipoprotein cholesterol levels of 3.5 mmol L (135.3 mg/dL), the overall sensitivity and specificity for confirming FH were 90.5% and 55.3%, respectively. As part of child-parent screening, in >90% of the families, the parent with reported higher cholesterol levels was positive for the familial genetic variant. The cohort-based prevalence of FH from the opt-out universal screening program was estimated to be 1 in 431 individuals (95% CI = 1/391-1/472). CONCLUSION: Universal 3-step FH screening approach in children enabled detection of most children and their parents in every generation screened at reasonable costs. Opt-out screening strategy might be preferable over opt-in screening strategy.
