RESUMEN
BACKGROUND: In order to minimize the spread of seasonal influenza epidemic to communities worldwide, the Korea Disease Control and Prevention Agency has issued an influenza epidemic alert using the influenza epidemic threshold formula based on the results of the influenza-like illness (ILI) rate. However, unusual changes have occurred in the pattern of respiratory infectious diseases, including seasonal influenza, after the coronavirus disease 2019 (COVID-19) pandemic. As a result, the importance of detecting the onset of an epidemic earlier than the existing epidemic alert system is increasing. Accordingly, in this study, the Time Derivative (TD) method was suggested as a supplementary approach to the existing influenza alert system for the early detection of seasonal influenza epidemics. METHODS: The usefulness of the TD method as an early epidemic alert system was evaluated by applying the ILI rate for each week during past seasons when seasonal influenza epidemics occurred, ranging from the 2013-2014 season to the 2022-2023 season to compare it with the issued time of the actual influenza epidemic alert. RESULTS: As a result of applying the TD method, except for the two seasons (2020-2021 season and 2021-2022 season) that had no influenza epidemic, an influenza early epidemic alert was suggested during the remaining seasons, excluding the 2017-2018 and 2022-2023 seasons. CONCLUSION: The TD method is a time series analysis that enables early epidemic alert in real-time without relying on past epidemic information. It can be considered as an alternative approach when it is challenging to set an epidemic threshold based on past period information. This situation may arise when there has been a change in the typical seasonal epidemic pattern of various respiratory viruses, including influenza, following the COVID-19 pandemic.

BACKGROUND: The advent of the omicron variant and the formulation of diverse therapeutic strategies marked a new epoch in the realm of coronavirus disease 2019 (COVID-19). Studies have compared the clinical outcomes between COVID-19 and seasonal influenza, but such studies were conducted during the early stages of the pandemic when effective treatment strategies had not yet been developed, which limits the generalizability of the findings. Therefore, an updated evaluation of the comparative analysis of clinical outcomes between COVID-19 and seasonal influenza is requisite. METHODS: This study used data from the severe acute respiratory infection surveillance system of South Korea. We extracted data for influenza patients who were infected between 2018 and 2019 and COVID-19 patients who were infected in 2021 (pre-omicron period) and 2022 (omicron period). Comparisons of outcomes were conducted among the pre-omicron, omicron, and influenza cohorts utilizing propensity score matching. The adjusted covariates in the propensity score matching included age, sex, smoking, and comorbidities. RESULTS: The study incorporated 1,227 patients in the pre-omicron cohort, 1,948 patients in the omicron cohort, and 920 patients in the influenza cohort. Following propensity score matching, 491 patients were included in each respective group. Clinical presentations exhibited similarities between the pre-omicron and omicron cohorts; however, COVID-19 patients demonstrated a higher prevalence of dyspnea and pulmonary infiltrates compared to their influenza counterparts. Both COVID-19 groups exhibited higher in-hospital mortality and longer hospital length of stay than the influenza group. The omicron group showed no significant improvement in clinical outcomes compared to the pre-omicron group. CONCLUSION: The omicron group did not demonstrate better clinical outcomes than the pre-omicron group, and exhibited significant disease severity compared to the influenza group. Considering the likely persistence of COVID-19 infections, it is imperative to sustain comprehensive studies and ongoing policy support for the virus to enhance the prognosis for individuals affected by COVID-19.

Since October 2021, severe acute hepatitis of unknown etiology in pediatric patients has been observed in many countries around the world. Adenovirus (mainly enteric adenovirus) was detected in more than 50% of the cases. Nationwide surveillance on acute hepatitis of unknown etiology in pediatric patients was started in May 2022 in Korea. Taking into account the severity of the illness and the urgency of the epidemiological situation worldwide, we report a summary of changes in adenovirus epidemiology during the past five years and six months in Korea.

Prolonged viral shedding of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in an immunocompromised host is a challenge as the treatment and infection control for chronic coronavirus disease 2019 infection is not well established and there is a potential risk of new variants emerging. A 48-year-old woman who underwent chemotherapy, including rituximab and steroid, had reactivation of SARS-CoV-2 68 days after the virus was first detected. She successfully recovered after receiving convalescent plasma and intravenous immunoglobulin. Genomic analysis demonstrated that viruses collected from the nasopharyngeal specimens at day 0 and day 68 had 18 different nucleotide mutations, implying within-host evolution after in-depth epidemiologic investigation.

BACKGROUND: Nonpharmacological interventions (NPIs) reduce the incidence of respiratory infections. After NPIs imposed during the coronavirus disease 2019 pandemic ceased, respiratory infections gradually increased worldwide. However, few studies have been conducted on severe respiratory infections requiring hospitalization in pediatric patients. This study compares epidemiological changes in severe respiratory infections during pre-NPI, NPI, and post-NPI periods in order to evaluate the effect of that NPI on severe respiratory infections in children. METHODS: We retrospectively studied data collected at 13 Korean sentinel sites from January 2018 to October 2022 that were lodged in the national Severe Acute Respiratory Infections (SARIs) surveillance database. RESULTS: A total of 9,631 pediatric patients were admitted with SARIs during the pre-NPI period, 579 during the NPI period, and 1,580 during the post-NPI period. During the NPI period, the number of pediatric patients hospitalized with severe respiratory infections decreased dramatically, thus from 72.1 per 1,000 to 6.6 per 1,000. However, after NPIs ceased, the number increased to 22.8 per 1,000. During the post-NPI period, the positive test rate increased to the level noted before the pandemic. CONCLUSION: Strict NPIs including school and daycare center closures effectively reduced severe respiratory infections requiring hospitalization of children. However, childcare was severely compromised. To prepare for future respiratory infections, there is a need to develop a social consensus on NPIs that are appropriate for children.

We examined Asian American college students' adherence to traditional values that are salient in Asian cultures, the students' perceptions of their mother's and father's adherence to the same values, and the discrepancies between the students and their mothers and fathers on the levels of adherence to these values. Based on the data from 301 participants who self-identified as Asian Americans, paired-samples t tests revealed that the child-parent cultural value discrepancies were present across all generational statuses of the participants with the children adhering less strongly to most of the value dimensions than their parents. The results based on correlational analyses showed that many types of value discrepancies were positively associated with the likelihood and seriousness of conflict. Several types of value discrepancies also were inversely associated with the participants' life satisfaction and self-esteem. In addition, the results from the PROCESS Macro for mediation analysis revealed significant mediation role of family conflict on the relationships between various types of value discrepancies and life satisfaction. The significant mediators were the likelihood and seriousness of family conflict and the family conflict about education and career decisions, and the value discrepancies centered on the values of conformity to norms, family recognition through achievement, and humility.

Actin-based stress fiber formation is coupled to microtubule depolymerization through the local activation of RhoA. While the RhoGEF Lfc has been implicated in this cytoskeleton coupling process, it has remained elusive how Lfc is recruited to microtubules and how microtubule recruitment moderates Lfc activity. Here, we demonstrate that the dynein light chain protein Tctex-1 is required for localization of Lfc to microtubules. Lfc residues 139-161 interact with Tctex-1 at a site distinct from the cleft that binds dynein intermediate chain. An NMR-based GEF assay revealed that interaction with Tctex-1 represses Lfc nucleotide exchange activity in an indirect manner that requires both polymerized microtubules and phosphorylation of S885 by PKA. We show that inhibition of Lfc by Tctex-1 is dynein dependent. These studies demonstrate a pivotal role of Tctex-1 as a negative regulator of actin filament organization through its control of Lfc in the crosstalk between microtubule and actin cytoskeletons.

BACKGROUND: Patient-Reported Outcomes (PROs) can be used to inform the clinical management of individuals, including patient self-management, care planning, and goal setting. Despite a rapid proliferation of technology to collect and integrate PROs in clinical care, uptake by patients and healthcare providers remains sub optimal. A consideration of systems factors to understand these challenges is needed. OBJECTIVES: To apply the socio-technical systems (STS) model as a framework for understanding the usability and functional requirements of patients collecting PRO data using applications (apps), and of healthcare providers using these data at the point of care in ambulatory settings. METHODS: With questions guided by the STS model, semi-structured interviews were conducted with eighteen patients and nine healthcare providers to elicit feedback about facilitators and barriers to successful use of PRO apps and PRO data in ambulatory settings. Patient participants were selected to fit into two categories: older, low utilizers of technology with less than a bachelor's degree, and younger higher utilizers of technology with at least a bachelor's degree. Participants were from primary and specialty care practices. Data were analyzed inductively to identify emergent themes. RESULTS: Younger patients were only interested in using a PRO app if they had an active health issue to track. The nine older patients preferred passive means of data collection if they were to track a health issue, and preferred direct contact with their healthcare provider and using office visits to share information. All patients desired optimal usability and emphasized bidirectional communication in an app that is transparent about privacy. All nine healthcare providers agreed that PRO data would be most useful and relevant if key patient populations were targeted based on the specific measure. In this case the healthcare providers noted potentially optimal utility of collecting physical function PRO data for patients 65 and older. Access to the data was highlighted by each healthcare provider stating that these data would be most useful if they were seamlessly integrated into the electronic health record. DISCUSSION: Several emergent themes were identified under the five selected dimensions of the STS model (clinical content, human computer interface, hardware and software computing infrastructure, people, and workflow and communication). Findings highlighted the continued need for innovative methods to obtain more rapid cycle, continuous feedback to identify system factors impacting use of these technologies. CONCLUSION: The STS model provides a comprehensive framework that can be applied to collect patient and healthcare provider feedback to better guide the design and implementation of new health information technology.
RESUMEN
PURPOSE: The effective use of patient-reported outcomes (PROs) can play a critical role in improving health care delivery and patient experience with care. However, PROs are not widely collected and used in clinical practice. This study aims to understand current opportunities and challenges with the use of PROs and the potential for health information technology (IT) to advance their use. METHODS: The Agency for Healthcare Research and Quality held two technical expert panel (TEP) meetings to discuss the current use of PROs, challenges, and opportunities in implementation, and how health IT can be leveraged to support effective PRO use in clinical practice. Results were synthesized to identify major themes and takeaways based on different stages of PRO data utilization. RESULTS: Findings from the TEP meetings indicated varying degrees of PRO usage in ambulatory care settings. Practices often lack a business case to collect PROs. Primary care physicians face more challenges than specialists in selecting appropriate PRO measures due to extensive variation in their patient populations. Providers also need training to use PRO data for shared decision making and population health management. Potential research areas to address PRO implementation challenges include measures harmonization, implementation process and workflow, electronic data collection and integration, and user-friendly data displays. CONCLUSIONS: Opportunities exist during different stages of PRO implementation to advance the use of PROs in clinical practice. Health IT can be utilized to address challenges in data collection, integration, and visualization to make PRO data accessible and understandable to patients and providers.

BACKGROUND: An outbreak of respiratory tract infection due to Respiratory Syncytial Virus (RSV) type B in a postpartum center was reported on February 1, 2017. Investigation was conducted to identify the magnitude, possible source of infection and risk factors for this outbreak on February 2, 2017. METHODS: A retrospective cohort study was conducted. A case was defined as a neonate having respiratory symptoms with or without fever and stayed at the postpartum center between January 1, 2017 and February 3, 2017. Daily records of neonates were reviewed, and all parents who stayed at the postpartum center were interviewed. Virological testing of real-time polymerase chain reaction was conducted for the neonates having respiratory illness, the parents and all staff members in the facility. RESULTS: This outbreak occurred between January 17, 2017 and February 7, 2017 in a postpartum center. Thirty-five (58.3%) neonates among 59 neonates were identified as cases and 12 neonates were confirmed to be RSV-B positive. The longer length of stay in the postpartum center is the only risk factor (Relative Risk = 8.10, 95% Confidence Interval:1.84-35.62, p < 0.01) in this outbreak. Two nursing staffs and eight parents were confirmed as RSV-B positive. CONCLUSIONS: Longer periods of stay in the postpartum center had an increased chance of becoming infected with RSV during this outbreak. Isolation of cases and temporary closure with environmental cleaning were recommended to the postpartum center.

A single institution retrospective evaluation of nivolumab following disease progression on bevacizumab in adults with recurrent glioblastoma (GBM) with an objective of determining progression free survival (PFS). There is no accepted therapy for recurrent GBM after failure of bevacizumab. 16 adults, ages 52-72 years (median 62), with recurrent GBM were treated. All patients had previously been treated with surgery, concurrent radiotherapy and temozolomide, and post-radiotherapy temozolomide. Bevacizumab (with or without lomustine) was administered to all patients at first recurrence. Patients were treated with nivolumab only (3 mg/kg) once every 2 weeks at second recurrence. One cycle of nivolumab was defined as 2 treatments. Neurological evaluation was performed bi-weekly and neuroradiographic assessment every 4 weeks. A total of 37 treatment cycles (median 2) were administered of nivolumab in which there were 14 Grade 2 adverse events (AEs) and Grade 3 AEs in two patients. No Grade 4 or 5 AEs were seen. Following 1 month of nivolumab, seven patients demonstrated progressive disease and discontinued therapy. No patient demonstrated a response though nine patients demonstrated neuroradiographic stable response. Survival in the entire cohort ranged from 2 to 6 months with a median of 3.5 months (CI 2.8, 4.2). Median and 6-month PFS at 6 months was 2.0 months (range 1-5 months; CI 1.3, 2.7) and 0% respectively. Nivolumab salvage therapy demonstrated no survival advantage in patients with recurrent bevacizumab refractory GBM emphasizing a continued unmet need in neuro-oncology.

There is no standard therapy for recurrent anaplastic glioma (AG). Salvage therapies include alkylator-based chemotherapy, re-resection with or without carmustine implants, re-irradiation and bevacizumab. Bendamustine is a novel bifunctional alkylator with CNS penetration never previously evaluated in AG. Assess response and toxicity of bendamustine in recurrent AG in a phase II trial. Adults with radiation and temozolomide refractory recurrent AG were treated with bendamustine. A cycle of bendamustine was defined as two consecutive days of treatment (100 mg/m2/day) administered once every 4 weeks. Success of treatment was defined as progression free survival (PFS) at 6 months of 40 % or better. Twenty-six adults [16 males; 10 females: median age 40 years (range 30-65)] were treated, 12 at first recurrence and 17 at second recurrence. Prior salvage therapy included re-resection (14), chemotherapy (11) and re-radiation (2). Grade 3 treatment-related toxicities included lymphopenia (11 patients; Grade 4 in 3), myalgia, pneumonia, diarrhea, leukopenia, allergic reaction and thrombocytopenia in one patient each. One patient discontinued therapy due to toxicity. There were five instances of bendamustine dose delays all due to lymphopenia. There were no dose reductions due to toxicity. The median number of cycles of therapy was 3 (range 1-8). Best radiographic response was progressive disease in 12 (46 %), stable disease in 13 (50 %) and partial response in 1 (4 %). Median, 6- and 12-month PFS was 2.7 months (range 1-52), 27 and 8 % respectively. In patients with recurrent AG refractory to Z, bendamustine has manageable toxicity and modest single agent activity though not meeting pre-specified study criteria.

PURPOSE: To describe the clinical features and management strategies in patients whose limbal stem cell (LSC) disease reversed with medical therapy. DESIGN: Retrospective case series. PARTICIPANTS: Twenty-two eyes of 15 patients seen at 3 tertiary referral centers between 2007 and 2011 with 3 months or more of follow-up. METHODS: Medical records of patients with medically reversible LSC disease were reviewed. Demographic data, causes, location and duration of disease, and medical inventions were analyzed. MAIN OUTCOME MEASURES: Primary outcomes assessed included resolution of signs of LSC disease and improvement in visual acuity. RESULTS: Causes of the LSC disease included contact lens wear only (13 eyes), contact lens wear in the setting of ocular rosacea (3 eyes), benzalkonium chloride toxicity (2 eyes), and idiopathic (4 eyes). Ophthalmologic findings included loss of limbal architecture, a whorl-like epitheliopathy, or an opaque epithelium arising from the limbus with late fluorescein staining. The superior limbus was the most common site of involvement (95%). The corneal epithelial phenotype returned to normal with only conservative measures, including lubrication and discontinuing contact lens wear in 4 patients (4 eyes), whereas in 11 patients (18 eyes), additional interventions were required after at least 3 months of conservative therapy. Medical interventions included topical corticosteroids, topical cyclosporine, topical vitamin A, oral doxycycline, punctal occlusion, or a combination thereof. All eyes achieved a stable ocular surface over a mean follow-up of 15 months (range, 4-60 months). Visual acuity improved from a mean of 20/42 to 20/26 (P < 0.0184). CONCLUSIONS: Disturbances to the LSC function, niche, or both may be reversible with medical therapy. These cases, which represent a subset of patients with LSC deficiency, may be considered to have LSC niche dysfunction.

This article reports the development and psychometric properties of the Interpersonal Shame Inventory (ISI), a culturally salient and clinically relevant measure of interpersonal shame for Asian Americans. Across 4 studies involving Asian American college students, the authors provided evidence for this new measure's validity and reliability. Exploratory factor analyses and confirmatory factor analyses provided support for a model with 2 correlated factors: external shame (arising from concerns about others' negative evaluations) and family shame (arising from perceptions that one has brought shame to one's family), corresponding to 2 subscales: ISI-E and ISI-F, respectively. Evidence for criterion-related, concurrent, discriminant, and incremental validity was demonstrated by testing the associations between external shame and family shame and immigration/international status, generic state shame, face concerns, thwarted belongingness, perceived burdensomeness, self-esteem, depressive symptoms, and suicide ideation. External shame and family shame also exhibited differential relations with other variables. Mediation findings were consistent with a model in which family shame mediated the effects of thwarted belongingness on suicide ideation. Further, the ISI subscales demonstrated high alpha coefficients and test-retest reliability. These findings are discussed in light of the conceptual, methodological, and clinical contributions of the ISI.

BACKGROUND: This study investigated the characteristics of coronavirus disease 2019 (COVID-19) among individuals with disabilities on a nationwide scale in the Republic of Korea, as limited research has examined this population. METHODS: Between January 1 and November 30, 2021, a total of 5,687 confirmed COVID-19 cases among individuals with disabilities were reported through the Korea Disease Control and Prevention Agency's COVID-19 web reporting system. Follow-up continued until December 24, and demographic, epidemiological, and clinical characteristics were analyzed. RESULTS: Individuals with disabilities represented approximately 1.5% of confirmed cases, with a mean age of 58.1 years. Most resided in or near metropolitan areas (86.6%) and were male (60.6%). Frequent sources of infection included home (33.4%) and contact with confirmed cases (40.7%). Many individuals (75.9%) had underlying conditions, and 7.7% of cases were severe. People with disabilities showed significantly elevated risk of severe infection (adjusted odds ratio [aOR], 1.63; 95% confidence interval [CI], 1.47-1.81) and mortality (aOR, 1.65; 95% CI, 1.43-1.91). Vaccination against COVID-19 was associated with significantly lower risk of severe infection (aORs for the first, second, and third doses: 0.60 [95% CI, 0.42-0.85], 0.28 [95% CI, 0.22-0.35], and 0.16 [95% CI, 0.05-0.51], respectively) and death (adjusted hazard ratios for the first and second doses: 0.57 [95% CI, 0.35-0.93] and 0.30 [95% CI, 0.23-0.40], respectively). CONCLUSION: Individuals with disabilities showed higher risk of severe infection and mortality from COVID-19. Consequently, it is critical to strengthen COVID-19 vaccination initiatives and provide socioeconomic assistance for this vulnerable population.
RESUMEN
Synovitis, acne, pustulosis, hyperostosis, osteitis (SAPHO) syndrome is a rare inflammatory condition associated with inflammatory bowel disease. Limited data exist on standardized management. We report a case of refractory SAPHO syndrome and ulcerative colitis (UC) treated successfully with tofacitinib. A 54-year-old man with UC presented with an intractable headache. A diagnosis of SAPHO syndrome was made based on the finding of sterile osteitis in the skull base and persistent severe UC. Symptoms, imaging, and endoscopy revealed persistent UC and osteitis despite multiple therapies. Tofacitinib was initiated and clinical remission was achieved. Tofacitinib is an effective treatment of refractory inflammatory bowel disease and SAPHO syndrome.
RESUMEN
BACKGROUND: Guided by the data from the surveillance system, public health efforts have contributed to reducing the burden of influenza in many countries. During the COVID-19 pandemic, many surveillance resources were directed at tracking the severe acute respiratory syndrome-Coronavirus 2. However, most countries have not reported surveillance evaluations during the COVID-19 pandemic. METHODS: Using the U.S. CDC surveillance evaluation method, we evaluated the influenza-like illness (ILI) sentinel surveillance performance in South Korea between January 2017 and September 2023. For the timeliness, we measured the mean time lag between the reports from the sentinel sites to the Korea Disease Control and Prevention Agency (KDCA) and surveillance result dissemination from KDCA. For the completeness, we measured the submission rate of complete reports per overall number of reports from each sentinel site to the KDCA. For the sensitivity, we calculated the correlation coefficient between the monthly number of ILI reports and the patients with ILI from the Korea national reimbursement data by either Pearson's or Spearman's test. For the representativeness, we compared the age-specific distribution of ILI between the surveillance data and the national reimbursement data using a chi-squared test. RESULTS: We found that the surveillance performance of timeliness (less than 2 weeks) and completeness (97 %-98 %) was stable during the study period. However, we found a reduced surveillance sensitivity (correlation coefficient: 0.73 in 2020, and 0.84 in 2021) compared to that of 2017-2019 (0.96-0.99), and it recovered in 2022-2023 (0.93-0.97). We found no statistical difference across the proportion of age groups between the surveillance and reimbursement data during the study period (all P-values > 0.05). CONCLUSIONS: Ongoing surveillance performance monitoring is necessary to maintain efficient policy decision-making for the control of the influenza epidemic. Additional research is needed to assess the overall influenza surveillance system including laboratory and hospital-based surveillance in the country.

Background: South Korea has implemented a hand, foot, and mouth disease (HFMD) surveillance system since 2009 to monitor incidence trends and identify disease burden. This nationwide surveillance involves a network of approximately 100 pediatric clinics that report all probable and confirmed HFMD cases. Following the COVID-19 pandemic, infectious disease surveillance systems must be evaluated to ensure the effective use of limited public health resources. Objective: This study aimed to evaluate the HFMD sentinel surveillance system in South Korea from 2017 to 2022, focusing on the transition period after the COVID-19 pandemic. Methods: We retrospectively reviewed the HFMD sentinel surveillance system from the Korea Disease Control and Prevention Agency using systematic guidelines for public health surveillance system evaluation developed by the US Centers for Disease Control and Prevention. We assessed the system's overall performance in 5 main factors: timeliness, stability, completeness, sensitivity, and representativeness (ie, the age and geographic distribution of sentinels). We rated these factors as weak, moderate, or good. Results: Our study showed that the completeness, sensitivity, and age representativeness of the HFMD surveillance performance were temporarily reduced to moderate levels from 2020 to 2021 and recovered in 2022, while the timeliness and geographic representativeness were maintained at a good level throughout the study period. The stability of the surveillance was moderate from 2017 to 2021 and weak in 2022. Conclusions: This is the first study to evaluate the HFMD surveillance system after the acute phase of the COVID-19 pandemic. We identified a temporarily reduced level of performance (ie, completeness, sensitivity, and age-specific representativeness) during the acute phase of the pandemic and good performance in 2022. Surveillance system evaluation and maintenance during public health emergencies will provide robust and reliable data to support public health policy development. Regular staff training programs and reducing staff turnover will improve HFMD surveillance system stability.

In the United States, jail frequently disrupts access to HIV care. EnhanceLink, a 10-site demonstration project promoting linkage to HIV primary care upon jail discharge, offered an opportunity to gauge how many releasees had favorable clinical outcomes. Individual level data were available on 1270 participants. Persons never discharged from the correctional environment were excluded. Multivariate logistic regression identified factors associated with viral suppression 6 months post discharge (6M-VL < 400). Among 1082 individuals eligible for follow-up evaluation, 25.7 % had 6M-VL < 400. 6M-VL < 400 was associated with case managers assessing whether help was needed for linkage to HIV-related medical services and clients keeping an appointment with a case manager. The adjusted odds ratio (aOR) of 6M-VL < 400 associated with attending a meeting with an HIV care provider within 30 days of release was 1.85. The results of this non-controlled, observational study support further development and rigorous evaluation of transitional care programs for HIV-positive jailed persons across the country.

UNLABELLED: Black individuals represent 13 % of the US population but 46 % of HIV positive persons and 40 % of incarcerated persons. The national EnhanceLink project evaluated characteristics of HIV-positive jail entrants at ten sites and explored associations between race and HIV disease state. Between 1/2008 and 10/2011, 1,270 study participants provided demographic and clinical data. Adjusted odds ratios (aORs) were calculated for advanced HIV disease (CD4 < 200 cells/mm(3)) and uncontrolled viremia (viral load > 400 copies/ml) for Black (n = 807) versus non-Black (n = 426) participants. Sixty-five percent of HIV-positive jail participants self-identified as Black. Among all participants, fewer than half had a high school diploma or GED, the median number of lifetime arrests was 15, and major mental illness and substance abuse were common. Black participants were more likely to be older than non-Black participants, and less likely to have health insurance (70 vs 83 %) or an HIV provider (73 vs 81 %) in the prior 30 days. Among all male study participants (n = 870), 20 % self-identified as homosexual or bisexual. Black male participants were more likely to be homosexual or bisexual (22 vs 16 %) and less likely to have a history of injection drug use (20 vs 50 %) than non-Black male participants. Advanced HIV disease was associated with self-identification as Black (aOR = 1.84, 95 % CI 1.16-2.93) and time since HIV diagnosis of more than two years (aOR = 3.55, 95 % CI 1.52-8.31); advanced disease was inversely associated with age of less than 38 years (aOR = 0.41, 95 % CI 0.24-0.70). Uncontrolled viremia was inversely associated with use of antiretroviral therapy (ART) in the prior 7 days (aOR = 0.25, 95 % CI 0.15-0.43) and insurance coverage in the prior 30 days (aOR = 0.46, 95 % CI 0.26-0.81). CONCLUSIONS: The racial disparities of HIV and incarceration among Black individuals in the US are underscored by the finding that 65 % of HIV-positive jail participants self-identified as Black in this ten-site study. Our study also found that 22 % of Black male participants self-identified as men who have sex with men (MSM). We believe these findings support jails as strategic venues to reach heterosexual, bisexual, and homosexual HIV-positive Black men who may have been overlooked in the community. Among HIV-positive jail entrants, Black individuals had more advanced HIV disease. Self-identification as Black was associated with a lower likelihood of having health insurance or an HIV provider prior to incarceration. HIV care and linkage interventions are needed within jails to better treat HIV and to address these racial disparities.
