RESUMEN
CONTEXT: Pneumonia is a leading cause of death in young infants. OBJECTIVES: To evaluate the efficacy of different antibiotic regimens to treat young infant pneumonia on critical clinical outcomes. DATA SOURCES: MEDLINE, Embase, CINAHL, World Health Organization (WHO) Global Index Medicus, Cochrane Central Registry of Trials. STUDY SELECTION: We included randomized controlled trials of young infants aged 0 to 59 days with pneumonia (population) comparing the efficacy of antibiotic regimens (intervention) with alternate regimens or management (control) on clinical outcomes. DATA EXTRACTION: We extracted data and assessed risk of bias in duplicate. We used Grading of Recommendations, Assessment, Development, and Evaluation to assess certainty of evidence. LIMITATIONS: Trials were heterogeneous, which precluded data pooling. RESULTS: Of 2601 publications screened, 10 randomized controlled trials were included. Seven trials were hospital-based (n = 869) and 3 were nonhospital-based (n = 4329). No hospital-based trials evaluated WHO-recommended first-choice regimens. One trial found the WHO-recommended second-choice antibiotic, cefotaxime, to have similar rates of treatment success as non-WHO-recommended regimens of either amoxicillin-clavulanate (RR 0.99, 95% confidence interval 0.82-1.10) or amoxicillin-clavulanate/cefotaxime (RR 1.02, 95% confidence interval 0.86-1.12). Among 3 nonhospital-based trials comparing oral amoxicillin to alternate regimens to treat isolated tachypnea among infants aged 7-59 days, there were no differences in treatment failure between amoxicillin and alternate regimens. Certainty of evidence was low or very low for all primary outcomes. CONCLUSIONS: We found limited evidence to support the superiority of any single antibiotic regimen over alternate regimens to treat young infant pneumonia.

The evolutionary origins of Bilateria remain enigmatic. One of the more enduring proposals highlights similarities between a cnidarian-like planula larva and simple acoel-like flatworms. This idea is based in part on the view of the Xenacoelomorpha as an outgroup to all other bilaterians which are themselves designated the Nephrozoa (protostomes and deuterostomes). Genome data can provide important comparative data and help to understand the evolution and biology of enigmatic species better. Here we assemble and analyse the genome of the simple, marine xenacoelomorph Xenoturbella bocki, a key species for our understanding of early bilaterian evolution. Our highly contiguous genome assembly of X. bocki has a size of ~111 Mbp in 18 chromosome like scaffolds, with repeat content and intron, exon and intergenic space comparable to other bilaterian invertebrates. We find X. bocki to have a similar number of genes to other bilaterians and to have retained ancestral metazoan synteny. Key bilaterian signalling pathways are also largely complete and most bilaterian miRNAs are present. Overall, we conclude that X. bocki has a complex genome typical of bilaterians, which does not reflect the apparent simplicity of its body plan that has been so important to proposals that the Xenacoelomorpha are the simple sister group of the rest of the Bilateria.
RESUMEN
The long and very long chain polyunsaturated fatty acids (LC-PUFAs) are preferentially transported by the mother to the fetus. Failure to supply LC-PUFAs is strongly linked with stillbirth, fetal growth restriction, and impaired neurodevelopmental outcomes. However, dietary supplementation during pregnancy is unable to simply reverse these outcomes, suggesting imperfectly understood interactions between dietary fatty acid intake and the molecular mechanisms of maternal supply. Here we employ a comprehensive approach combining untargeted and targeted lipidomics with transcriptional profiling of maternal and fetal tissues in mouse pregnancy. Comparison of wild-type mice with genetic models of impaired lipid metabolism allows us to describe maternal hepatic adaptations required to provide LC-PUFAs to the developing fetus. A late pregnancy-specific, selective activation of the Liver X Receptor signalling pathway dramatically increases maternal supply of LC-PUFAs within circulating phospholipids. Crucially, genetic ablation of this pathway in the mother reduces LC-PUFA accumulation by the fetus, specifically of docosahexaenoic acid (DHA), a critical nutrient for brain development.

Seric hyperviscosity syndrome is a medical emergency linked to hyperproteinemia. The clinical diagnosis hinges on a triad of symptoms: mucosal hemorrhages, visual disturbances, and neurological disorders, observed in the most severe cases. Diagnosis is swiftly confirmed through an urgent fundoscopic examination. Therapeutic plasma exchange is the primary treatment for severe cases or following confirmation by fundoscopy. Laboratory tests predominantly identify the syndrome's etiology, with Waldenström's macroglobulinemia (characterized by a marked IgM peak) being the most common cause, followed by multiple myeloma and cryoglobulinemias. To prevent recurrence, targeted treatment of the underlying cause is implemented following plasma exchange sessions.
RESUMEN
Gestational trophoblastic neoplasia (GTN) with spinal metastasis is rare with few documented cases worldwide. Few studies have explored chemotherapy combined with radiotherapy in the treatment of such cases. However, because of its rarity, there is still no standardized treatment regimen. A 34-year-old Gravida 1 Para 0 (0010) was diagnosed with GTN with metastasis to the lumbosacral spine, resulting in conus medullaris syndrome with lumbar radiculopathy. She presented with a 14-month history of amenorrhea, left lower extremity pain, and urinary and bowel retention. On examination, there was a 10.0 × 7.0 cm lumbosacral mass and atrophy of the left lower extremity. Transvaginal ultrasound showed a cul de sac mass, and diluted ß-human chorionic gonadotropin (ß-hCG) titer was markedly elevated at more than 1000 000 mIU/mL. Magnetic resonance imaging (MRI) of the lumbosacral spine showed an ill-defined sacral mass measuring 13.3 × 11.5 × 6.3 cm with spinal canal, bone, muscle, and nerve root involvement. She was treated with 10 cycles of EMACO and palliative radiotherapy with 10 sessions of 30 Gy of external beam radiation therapy directed toward the lumbosacral mass. Repeat MRI showed a decrease in size of the mass to 6.6 × 8.2 × 4.1 cm with concurrent decrease in ß-hCG to 1.30 mIU/ml, and resolution of leg pain and urinary and bowel symptoms. She was declared to be in remission 3 months after the last cycle of EMACO.
RESUMEN
BACKGROUND: Many organizations recommend clinicians use structured communication processes, referred to as "shared decision making," to improve patient-reported outcomes for patients considering lung cancer screening (LCS). RESEARCH QUESTION: Which components of high-quality patient-centered communication are associated with decision regret and distress? STUDY DESIGN AND METHODS: We conducted a prospective, longitudinal, repeated measures, cohort study among patients undergoing lung cancer screening in three different healthcare systems. We surveyed participants using validated measures of decision regret, decision satisfaction, distress, and patient-clinician communication domains up to a year after the low-dose computed tomography (LDCT) for LCS. For longitudinal analyses, we applied a series of generalized estimating equations to measure the association of the "patient as person" communication domain, screening knowledge, and decision concordance with decision regret and distress. RESULTS: When assessed 2-4 weeks after the LDCT, 202 (58.9%) and 8 (2.3%) of 343 total respondents reported mild and moderate/severe decision regret, respectively, while 29 (9.2%) participants of 315 total reported mild distress and 19 (6.0%) moderate or greater distress. The mean ± SD decision satisfaction scores (0 to 10 scale) were 9.82 ± 0.89, 9.08 ± 1.54, and 6.13 ± 3.40 among those with no, mild, and moderate/severe regret respectively. Distress scores remained low after the LDCT, even among those with nodules. Patient-centered communication domains were not associated with decision regret or distress. INTERPRETATION: Patients undergoing LCS rarely experience moderate or greater decision regret and distress. Although many participants reported mild decision regret, most were very satisfied over the year after their LDCT for LCS. Communication processes were not associated with regret and distress, suggesting that it may be challenging for communication interventions to reduce the harms of LCS.
RESUMEN
Post-transcriptional mechanisms are fundamental safeguards of progenitor cell identity and are often dysregulated in cancer. Here, we identified regulators of P-bodies as crucial vulnerabilities in acute myeloid leukaemia (AML) through genome-wide CRISPR screens in normal and malignant haematopoietic progenitors. We found that leukaemia cells harbour aberrantly elevated numbers of P-bodies and show that P-body assembly is crucial for initiation and maintenance of AML. Notably, P-body loss had little effect upon homoeostatic haematopoiesis but impacted regenerative haematopoiesis. Molecular characterization of P-bodies purified from human AML cells unveiled their critical role in sequestering messenger RNAs encoding potent tumour suppressors from the translational machinery. P-body dissolution promoted translation of these mRNAs, which in turn rewired gene expression and chromatin architecture in leukaemia cells. Collectively, our findings highlight the contrasting and unique roles of RNA sequestration in P-bodies during tissue homoeostasis and oncogenesis. These insights open potential avenues for understanding myeloid leukaemia and future therapeutic interventions.
RESUMEN
Topoisomerase I (TOP1) is an essential enzyme that relaxes DNA to prevent and dissipate torsional stress during transcription. However, the mechanisms underlying the regulation of TOP1 activity remain elusive. Using enhanced cross-linking and immunoprecipitation (eCLIP) and ultraviolet-cross-linked RNA immunoprecipitation followed by total RNA sequencing (UV-RIP-seq) in human colon cancer cells along with RNA electrophoretic mobility shift assays (EMSAs), biolayer interferometry (BLI), and in vitro RNA-binding assays, we identify TOP1 as an RNA-binding protein (RBP). We show that TOP1 directly binds RNA in vitro and in cells and that most RNAs bound by TOP1 are mRNAs. Using a TOP1 RNA-binding mutant and topoisomerase cleavage complex sequencing (TOP1cc-seq) to map TOP1 catalytic activity, we reveal that RNA opposes TOP1 activity as RNA polymerase II (RNAPII) commences transcription of active genes. We further demonstrate the inhibitory role of RNA in regulating TOP1 activity by employing DNA supercoiling assays and magnetic tweezers. These findings provide insight into the coordinated actions of RNA and TOP1 in regulating DNA topological stress intrinsic to RNAPII-dependent transcription.
RESUMEN
Background: Access to a primary care provider is not guaranteed for many living in rural settings. Notably, rural populations experience a higher degree of burden from chronic diseases compared to urban-dwellers. For example, diabetes can go undiagnosed and undertreated with lack of primary care. To address these care gaps at a large, rural family medicine practice in western North Carolina, a multidisciplinary pharmacist-led diabetes clinic was developed. Objectives: This article describes the implementation, evolution, and impact of the diabetes management clinic and explores future directions for improving the experience of patients and health care providers. Practice Description and Innovation: The diabetes management clinic at Mountain Area Health Education Center (MAHEC) is a pharmacy resident-led interdisciplinary clinic incorporating nutrition and pharmacy learners to provide patient care in both telehealth and in-office settings. Since its inception in 2018, the clinic has facilitated meaningful learning opportunities for students and residents and helped patients manage their diabetes in a multifaceted approach. Evaluation Methods: A retrospective, cross-sectional study evaluated diabetes-related outcomes for 80 patients seen in the diabetes management clinic during twelve months of appointments. The primary outcome measure was change in A1c from baseline. Results: Among patients with a follow-up A1c during the study (n=64), there was a mean reduction in A1c by 0.79% from baseline. Additionally, among those with a second follow-up A1c available (n=32), there was a mean reduction from baseline in A1c of 1.42%. Conclusion: The utilization of pharmacy residents as part of an interdisciplinary diabetes management clinic can extend access to care for underserved patients. The clinic also serves as a structured teaching clinic for interdisciplinary learners, and it has contributed to positive clinical outcomes, strong interprofessional collaboration, and expansion of experiential education opportunities since its inception in 2018.
RESUMEN
The human mammary gland represents a highly organized and dynamic tissue, uniquely characterized by postnatal developmental cycles. During pregnancy and lactation, it undergoes extensive hormone-stimulated architectural remodeling, culminating in the formation of specialized structures for milk production to nourish offspring. Moreover, it carries significant health implications, due to the high prevalence of breast cancer. Therefore, gaining insight into the unique biology of the mammary gland can have implications for managing breast cancer and promoting the well-being of both women and infants. Tissue engineering techniques hold promise to narrow the translational gap between existing breast models and clinical outcomes. Here, we provide an overview of the current landscape of breast tissue engineering, outline key requirements, and the challenges to overcome for achieving more predictive human breast models. We propose methods to validate breast function and highlight preclinical applications for improved understanding and targeting of breast cancer. Beyond mammary gland physiology, representative human breast models can offer new insight into stem cell biology and developmental processes that could extend to other organs and clinical contexts.
RESUMEN
Objectives: To evaluate relapses in giant cell arteritis (GCA), investigate the utility of vascular ultrasound to detect relapses, and develop and assess a composite score for GCA disease activity (GCAS) based on clinical symptoms, ultrasound imaging activity, and C-reactive protein (CRP). Methods: Patients with GCA were prospectively followed with scheduled visits, including assessment for clinical relapse, protocol ultrasound examination, and CRP. At each visit, patients were defined as having ultrasound remission or relapse. GCAS was calculated at every visit. Results: The study included 132 patients, with a median follow-up time of 25 months [interquartile range (IR) 21]. The clinical relapse rate was 60.6%. There were no differences in relapse rates between GCA subtypes (cranial-GCA, large vessel (LV)-GCA, and mixed-GCA) (p = 0.83). Ultrasound yielded a sensitivity of 61.2% and a specificity of 72.3% for diagnosing GCA- relapse in our cohort. In 7.7% of follow-up visits with clinical relapses, neither high CRP nor findings of ultrasound relapse were registered. In comparison, in 10.3% of follow-up visits without symptoms of clinical relapse, there were both a high CRP and findings of ultrasound relapse. Conclusion: We found moderate sensitivity and specificity for ultrasound as a monitoring tool for relapse in this prospective cohort of GCA patients. The extent or subtype of vasculitis at the diagnosis did not influence the number of relapses. Based on a combination of clinical symptoms, elevated CRP, and ultrasound findings, a composite score for GCA activity is proposed.
RESUMEN
Propagule dispersal is a crucial aspect of the survival and reproduction of sessile organisms, such as plants and fungi. As such, the colours of fleshy fruits serve as a visual cue for animal dispersers. However, little is known about how, or whether, specific traits of fungal fruiting bodies, such as colour or shape, attract animal dispersers, and additionally the identities of fungal dispersers are poorly understood. Globally, most truffle-like fungi are dull-coloured, subterranean, and likely have scents that are attractive to mammalian dispersers. In Aotearoa-New Zealand, however, brightly coloured truffle-like fungi that emerge from the forest floor have seemingly proliferated. This proliferation has prompted the hypothesis that they are adapted to dispersal by a bird-dominated fauna. In our study, we used the literature and citizen science data (GBIF) to explore whether colourful species occur at a higher proportion of the total truffle-like fungi flora in Aotearoa-New Zealand than elsewhere in the world. In addition, we tested for a relationship between biotic factors (avian frugivory and forest cover) and abiotic factors (precipitation, radiation, and temperature) and the prevalence of brightly coloured truffle-like fungi across the world. The most colourful truffle-like fungi are in three defined regions: Australia, South and Central America and the Caribbean, and Aotearoa-NZ. Potential dispersers and the environment both relate to the distribution of truffle-like fungi: we found that increasing levels of frugivory were associated with higher proportions of colourful truffle-like fungi. This finding provides new insights into drivers of certain fungal traits, and their interactions between birds and fungi. Unique ecosystems, such as Aotearoa-NZ's bird-dominated biota, provide fascinating opportunities to explore how plants and fungi interact with the sensory systems of animals.

Smoke-free laws (SFL) are more effective with public support. This study investigated the smoking prevalence, public perceptions of smoking rules, and support for comprehensive SFL among 1047 people who smoke (PWS) and 206 people who do not smoke (PNS) aged ≥18 in the 2020 International Tobacco Control Malaysia Survey. Smoking prevalence was highest in nighttime entertainment venues (85.7%), non-air-conditioned eateries (49.7%), and indoor workplaces (34.6%). Respondents reported that smoking was banned in most indoor workplaces (81.7% PNS, 69.2% PWS), air-conditioned eateries (84.7% PNS, 75.7% PWS), and non-air-conditioned eateries (81.2% PNS, 78.7% PWS), but much less so in nighttime entertainment venues (30.1% PNS, 24.6% PWS). Support for comprehensive SFL in public venues was highest among PNS (≥84.9%) but still substantial among PWS (≥49.9%). PWS under 40, Malay, married, and aware of smoking rules supported SFL more. Robust SFL enforcement is essential in Malaysia to reduce secondhand smoke exposure in public places.
RESUMEN
The potential-dependent negative fractional reaction orders with respect to the CO partial pressures were measured for CO2 electroreduction (CO2R) on Au under mass-transfer-controlled conditions using a rotating ring-disk electrode setup. At high overpotentials, the CO reaction order approaches -1 due to enhanced CO adsorption on Au, which is supported by kinetic analysis and density functional theory (DFT) simulations. This work illustrates that the CO site-blocking effect cannot be ignored, even on a weak CO-binding metal such as Au in the electrochemical environment. The CO site-blocking effect can greatly hamper the activity and the selectivity of the CO2R to CO. This observation enriches the current mechanistic understanding of the CO2R and could have significant implications not only in the theoretical modeling of the CO2R but also in the evaluation of intrinsic CO2R activity at practical current density and high conversion conditions.
RESUMEN
Purpose: Arterial and venous thromboembolism are a leading cause of mortality. Direct oral anticoagulants (DOACs) are highly effective in both stroke prevention and prevention of venous thrombotic events. Medication adherence is a prerequisite for optimal protection against thromboembolic complications. Recent studies have shown that good adherence cannot be taken for granted by DOACs. In this cross-sectional study adherence among DOAC users was investigated and associations between beliefs about medication, perceived side effects and adherence were explored. Patients and Methods: We included 100 randomly selected adult DOAC users visiting one of the two participating Dutch community pharmacies in the summer of 2020. The self-reported adherence (primary outcome) was assessed with the Medication Adherence Rating Scale-5 (MARS-5) using three different cut-off scores. Beliefs about DOACs were assessed with the Beliefs about Medicine Questionnaire Specific (BMQ-S), while side effects and side effect burden were assessed with a self-developed questionnaire based on the Lareb Intensive Monitoring (LIM) system. Results: Of the participants, 9% reported non-adherence on the primary MARS-5 cut-off score <24. For the MARS-5 scores <23 and <25 non-adherence percentages of, respectively, 3 and 33% were calculated. Associations were found between adherence and both side effects and side effect burden, regardless of the MARS-5 cut-off score. Bruising and minor bleeds were the most reported side effects (both 20%). For all patients, the necessity beliefs outweighed the concern beliefs. No associations were found between adherence and either gender, indication, DOAC or dosage. Conclusion: This study confirms that adherence in patients on DOACs cannot be taken for granted. High necessity beliefs do not guarantee good adherence, as side effects impair adherence even in patients having high necessity beliefs. Therefore, we recommend that both physicians and pharmacists evaluate both adherence and side effects with these patients on a regular base.
The issue Thrombosis affects many people. Complications like stroke and lung embolism are a major cause of health damage, disability and even death. Direct oral anticoagulants (DOACs) are highly effective drugs at preventing these complications. However, patients need to take their medication properly to get the best protection. Recent studies showed that not all patients consistently take their DOACs. What's new? In this study, we discovered that patients experiencing bothersome side effect were less likely to stick to their medication schedule. The most common side effects reported were bruising and minor bleeding, by 20% each. There were no differences in how well patients took their medication based on gender, medical condition, type of DOAC or prescribed dosage. Most patients believed their medication was necessary for their health. Why is this important? This study shows that side effects hinder patients taking their medication correctly even when they believe their medication is necessary for their health. This means that patients on DOAC therapy who experience side effects may be less protected against stroke and lung embolism. Therefore, we recommend that doctors and pharmacists regularly check in with patients about any side effects they experience and how consistently they take their DOACs. What's next? This study highlights the importance of developing, testing, and implementing practical tools to find and help patients who do not take their DOACs correctly, to ensure they are better protected against blood clots.

Most physical activity (PA) maintenance research has concerned adherence to small-scale interventions or infrequent observation in cohort studies. We analysed individual attendance trajectories and their drivers in a large-scale 'real-world' community-based weekly PA event (parkrun) cohort in Australia. Data were weekly attendance (walking/running) of 223 224 unique parkrun participants over their first 3 years of participation. An unweighted moving average of participation in the preceding 12 weeks from the 12th week since the first participation to the 156th week was calculated and submitted to a cluster analysis of attendance patterns. Association of individual- (demographic, personal parkrun performance) and site-level (aggregated site-level participant characteristics and area-level measures) covariates with cluster membership was estimated with multinomial logistic regression models. We identified four groups: Few-Timers (76.4%), Decliners (12.4%), Low Maintainers (6.9%) and High Maintainers (4.3%). In the first 12 weeks, attendances averaged 2, 6, 5 and 7.5 times for each cluster, respectively, and by 52 weeks, they were 0.17, 1.9, 3.4 and 7.6 times, respectively. Continuing participation (vs Few-Timers) was strongly associated with faster personal finish times, but slower performance at the site level. Higher running club/group membership at a participant's parkrun predicted higher odds of being a High Maintainer. Our identification of a Low Maintainer group shows a community-based initiative may sustain interest, despite not requiring continuous or near-continuous attendance. Where someone is placed 'in the pack' locally and degree of identification with others in the group may be bidirectionally associated with attendance, underscoring the importance of considering social environment of PA maintenance.

Microalgae have emerged as a promising source of biomass to produce renewable biofuels due to their ability to synthesize high-energy density compounds of commercial interest. This study proposes an approach for pilot-scale oil extraction, purification by fractional distillation, hydrocarbon characterization by gas chromatography coupled to mass spectrometry (GC-MS), evaluation of physicochemical parameters of the produced hydrocarbons, preliminary cost analysis, and challenges and future opportunities for green diesel on a commercial scale. Here, the microalgae Tetradesmus obliquus was cultivated in 12 m³ photobioreactors using biodigested swine waste as a culture medium. The resulting biomass was subjected to drying and harvesting, followed by oil extraction using a hot solvent extraction method, followed by distillation to purify the compounds. Three different extraction and distillation experiments were conducted, each using different solvent combinations. The results obtained revealed that extraction with a solvent blend, composed of hexane and ethanol, provided more significant yields compared to extraction with pure hexane. GC-MS analysis showed the presence of alkanes and alkenes in the oil samples, and the proportion of solvent used in the extraction directly influenced the production of alkanes. Additionally, specific hydrocarbons such as 4-methyl-1-decene, 8-heptadecene, 1-pentadecene, 9-heneicosene, and 2-dodecene were identified. The evaluation of the physicochemical parameters demonstrated that the calorific value of the distilled oil samples is within the range of typical values for petroleum diesel. However, it was observed that the distilled oil samples had higher sulfur content compared to conventional diesel. Regarding the cost analysis, it was found that it varies depending on the experimental conditions. In particular, the process using a solvent mixture of 70% hexane and 30% ethanol proved to be more economical than the others, since it extracted a greater quantity of oil with a lower initial biomass requirement. In summary, this microalgae-derived hydrocarbon production process is promising and offers insights for compound purification and future biofuel applications.
RESUMEN
OBJECTIVE: The objective of this study was to describe feeding practices and weight status in a cohort of children with congenital Zika syndrome (CZS) in northeastern Brazil. METHODS: This longitudinal study of children with CZS (N = 156) included data collection on child feeding practices and weight status at five timepoints between 2018 and 2022. The average age of the children was 32.1 months at enrollment and 76.6 months at the fifth assessment. Multilevel models, with repeated observations nested within children, were used to estimate time-related differences in each outcome. RESULTS: Use of enteral feeding, such as gastrostomy, increased from 19.2% to 33.3% over 4 years (p < .001). Among children who did not exclusively use an enteral feeding method, the percentage experiencing at least one dysphagia-associated behavior, such as coughing or gagging, increased from 73.9% to 85.3% (p = .030) while consuming liquids and from 36.2% to 73.5% (p = .001) while consuming solids. Based on weight-for-age z-scores, the percentage of children who were moderately or severely underweight increased from 42.5% to 46.1% over the 4 years but was not statistically significant. Children exclusively using an enteral feeding method had significantly decreased odds of being underweight at assessments 3, 4, and 5. CONCLUSIONS: These data highlight the ongoing and increasing challenges of feeding young children with CZS. Our findings elucidate the physiological reasons children with CZS may be underweight and point to intervention targets, such as enteral feeding, to improve their feeding practices.
RESUMEN
OBJECTIVES: In the United States, hepatitis C is the most commonly reported bloodborne infection. It is a leading cause of liver cancer and death from liver disease and imposes a substantial burden of hospitalization. We sought to describe regional differences in hepatitis C virus (HCV)-related hospitalizations during 2012 through 2019 to guide planning for hepatitis C elimination. METHODS: We analyzed discharge data from the National Inpatient Sample for 2012 through 2019. We considered hospitalizations to be HCV-related if (1) hepatitis C was the primary diagnosis or (2) hepatitis C was any secondary diagnosis and the primary diagnosis was a liver disease-related condition. We analyzed demographic and clinical characteristics of HCV-related hospitalizations and modeled the annual percentage change in HCV-related hospitalization rates, nationally and according to the 9 US Census Bureau geographic divisions. RESULTS: During 2012-2019, an estimated 553 900 HCV-related hospitalizations occurred in the United States. The highest hospitalization rate (34.7 per 100 000 population) was in the West South Central region, while the lowest (17.6 per 100 000 population) was in the West North Central region. During 2012-2019, annual hospitalization rates decreased in each region, with decreases ranging from 15.3% in the East South Central region to 48.8% in the Pacific region. By type of health insurance, Medicaid had the highest hospitalization rate nationally and in all but 1 geographic region. CONCLUSIONS: HCV-related hospitalization rates decreased nationally and in each geographic region during 2012-2019; however, decreases were not uniform. Expanded access to direct-acting antiviral treatment in early-stage hepatitis C would reduce future hospitalizations related to advanced liver disease and interrupt HCV transmission.
