The current status and global trends of clinical trials related to robotic surgery: a bibliometric and visualized study.

Conducting clinical trials can evaluate the effectiveness and safety of surgical robots. To promote the advancement of academic robotic programs in surgery, this study captures the development trend and research hotspots of clinical trials related to surgical robots by bibliometric analysis. Bibliometrix package in R software was used to analyze the publication year, authors, countries, institutes, and journals. The visualization maps of keywords were formed using VOSviewer. The keywords with the strongest citation bursts and the institutional collaboration map were created by CiteSpace. Urology dominates with 31.3% of publications and the controlled clinical trials in urology and orthopedic accounted for the highest proportion, reaching 73%. North America, the USA, and Seoul National University lead in productivity. The most productive country, region and institution are North America, USA and Seoul National University, respectively. The trend of collaboration is regional instead of international. Keyword and burst keyword analysis revealed a primary focus in clinical research on robotic surgery: evaluating process improvements, comparing robotic and traditional surgery, and assessing feasibility. Long-term clinical trials assess surgical robots not only intraoperative performance but also postoperative complications and overall surgical outcomes. The development in the field is unbalanced between regions and countries. To promote multi-center clinical trials, governments can streamline review procedures and establish international consensus review standards, while academic institutions can form academic alliances. Also, the study offers recommendations for the development of academic robotic programs and regional collaboration units in robotic surgery, which may provide researchers with a strong reference for future research.

Increasing Antibiotic-Resistant Infections With Inpatient Endoscopic Retrograde Cholangioscopies (ERCP) Is Associated With Higher Mortality in the United States: A Cross-sectional Cohort Study.

This study aims to investigate associated mortality with inpatient endoscopic retrograde cholangiopancreatography (ERCP) with and without resistant infections. The co-primary objective compares frequencies of inpatient ERCP with resistant infections to overall hospitalizations with resistant infections. The risks of inpatient antibiotic-resistant organisms are known, but the associated mortality for inpatient ERCP is unknown. We aim to use a national database of hospitalizations and procedures to understand trends and mortality for patients with antibiotic-resistant infections during inpatient ERCP. The largest publicly available all-payer inpatient database in the United States (National Inpatient Sample) was used to identify hospitalizations associated with ERCPs and antibiotic-resistant infections for MRSA, VRE, ESBL, and MDRO. National estimates were generated, frequencies were compared across years, and multivariate regression for mortality was performed. From 2017 to 2020, national weighted estimates of 835,540 inpatient ERCPs were generated, and 11,440 ERCPs had coincident resistant infections. Overall resistant infection, MRSA, VRE, and MDRO identified at the same hospitalization of inpatient ERCPs were associated with higher mortality (OR CI(95%): Overall: 2.2(1.77-2.88), MRSA: 1.90 (1.34-2.69), VRE: 3.53 (2.16-5.76), and MDRO: 2.52 (1.39-4.55)). While overall hospitalizations with resistant infections have been decreasing annually, there has been a yearly increase in admissions requiring ERCPs with simultaneous resistant infections ( P =0.001-0.013), as well as infections with VRE, ESBL, and MDRO ( P =0.001-0.016). Required Research Practices for Studies Using the NIS scoring was 0, or the most optimal. Inpatient ERCPs have increasing coincident resistant infections and are associated with higher mortality. These rising infections during ERCP highlight the importance of endoscopy suite protocols and endoscopic infection control devices.

Racial, biological sex, and geographic disparities of venous thromboembolism in the United States, 2016 to 2019

BackgroundVenous thromboembolism (VTE) stands as the leading cause of preventable death within hospitals in the United States. Although there have been some studies investigating the incidence rates of VTE, there has yet to be a large-scale study elucidating disparities in sex, race, income, region, and seasons in patients with VTE. The goal of this study was to report the disparities in race, sex, income, region, and seasons in patients with VTE, pulmonary embolism (PE), and deep vein thrombosis (DVT), in hospitalized patients from 2016 to 2019. MethodsWe used the United States National Inpatients Sample database to identify inpatients diagnosed with PE, DVT, and PE and DVT from 2016 to 2019. The inpatient incidence per thousand was calculated for sex and race using the weighted sample model. The regional and monthly incidence of DVT and PE per thousand inpatients and risk of incidence were calculated. Patients' characteristics including hospital type, bed size, median length of stay, median total charges, and mortality were also collected. ResultsWe examined 455,111 cases of VTE, 177,410 cases of DVT, 189,271 cases of PE, and 88,430 cases of both DVT and PE combined. Over the study period, we observed a statistically significant trend among PE hospitalization incidences. There was a strong and positive correlation between DVT and PE inpatients. Black inpatients had the highest cumulative incidence of hospitalizations in all cohorts with 10.36 per 1000 in PE and 9.1 per 1000 in DVT. Asian and Pacific Islander inpatients had the lowest cumulative incidence with 4.42 per 1000 in PE and 4.28 per 1000 in DVT. Females showed the lowest cumulative incidence with 7.47 per 1000 in PE and 6.53 per 1000 in DVT. The Mountain region was the highest among PE hospitalizations with 9.62 per 1000. For DVT, the Middle Atlantic region was the highest at 8.65 per 1000. The in-hospital mortality rate was the highest among the PE hospitalizations at 7.3%. Also, the trend analysis showed significant increases among all groups. ConclusionsOver the study period (2016-2019), we report the racial, biological sex, and geographical disparities from the National Inpatient Sample database, highlighting that Black inpatients had the highest incidence of PE and DVT, whereas Asian/Pacific Islander inpatients had the lowest incidences of PE and DVT. Moreover, women had a lower incidence compared with men. The observed regional variations indicated that the incidence of PE was highest in the Mountain region, whereas the incidence of DVT was lowest in the Middle Atlantic region. There was an increase in the mortality of inpatients diagnosed with VTE reflecting the growing burden of this condition in the US health care system.

Incidence of ocular pathology following bariatric surgery for with morbid obesity across a large United States National Database

Background/ObjectivesBariatric surgery, as indicated for treatment of morbid obesity, has been studied in association with short term effects on ocular pathology. However, effects of surgery on postoperative disease incidence is largely unknown.Subjects/MethodsIn this retrospective cohort study, the TriNetX United States Collaborative Network national database, was queried for patients with an ICD-10 code for morbid obesity and a procedural code for bariatric surgery. Patients were propensity score matched across baseline demographics at the time of surgery and compared to those presenting with an ICD10 code for morbid obesity with no records of a procedural code for bariatric surgery, identifying 42,408 patients per cohort. New diagnoses or procedural codes found after the surgical index date for diabetic retinopathy, age-related macular degeneration, glaucoma, low vision, and blindness along with pertinent treatment metrics were monitored.ResultsBariatric surgery was found to be associated with reduced future risk of diabetic retinopathy (RR: 0.283; 95% CI: 0.252–0.319), macular edema (RR: 0.224; 95% CI: 0.170–0.297), vitreous hemorrhage (RR: 0.459; 95% CI: 0.323–0.653), ocular hypertension (RR: 0.387; 95% CI: 0.387–0.487), glaucoma (RR: 0.360; 95% CI: 0.326–0.399), use of ocular pressure lowering medications (RR: 0.565; 95% CI: 0.496–0.644), age-related macular degeneration (RR: 0.628; 95% CI: 0.447–0.882), cataract surgery (RR: 0.524; 95% CI: 0.448–0.612), and low vision and blindness (RR: 0.328; 95% CI: 0.294–0.365) compared to patients not surgically managed.ConclusionsThe present analysis comprising a large US cohort of patients suggests that bariatric surgery is associated with a decreased risk of future ocular morbidity and mortality.

Reported Unmet Hearing Aid Need in Older People With Dementia: The US National Core Indicators Survey

ObjectivesHearing aids have important health benefits for older adults with Alzheimer disease and related dementias (ADRD); however, hearing aid adoption in this group is low. This study aimed to determine where to target hearing aid interventions for American long-term care recipients with ADRD by examining the association of ADRD and residence type with respondent-reported unmet hearing aid need. Design, Setting, and ParticipantsThis cross-sectional study used data from the United States National Core Indicators–Aging and Disabilities survey (2015-2019) for long-term care recipients aged ≥65 years. MethodsWe used multivariable logistic regression to model the likelihood of reporting unmet hearing aid need conditional on ADRD status and residence type (own/family house or apartment, residential care, or nursing facility/home), adjusting for sociodemographic factors and response type (self vs proxy). ResultsOf the 25,492 respondents [median (IQR) age, 77 (71, 84) years; 7074 (27.8%) male], 5442 (21.4%) had ADRD and 3659 (14.4%) owned hearing aids. Residence types were 17,004 (66.8%) own/family house or apartment, 4966 (19.5%) residential care, and 3522 (13.8%) nursing home. Among non–hearing aid owners, ADRD [adjusted odds ratio (AOR) 0.90, 95% CI 0.80-1.0] and residence type were associated with respondent-reported unmet hearing aid need. Compared to the nursing home reference group, respondents in their own/family home (AOR 1.85, 95% CI 1.61-2.13) and residential care (AOR 1.30, 95% CI 1.10-1.53) were more likely to report unmet hearing aid need. This pattern was significantly more pronounced in people with ADRD than in those without, stemming from an interaction between ADRD and residence type. Conclusions and ImplicationsAmerican long-term care recipients with ADRD living in their own/family home are more likely to report unmet hearing aid need than those with ADRD in institutional and congregate settings. This information can inform the design and delivery of hearing interventions for older adults with ADRD.

Risk of respiratory diseases among hospitalized patients with hidradenitis suppurativa.

Hidradenitis suppurativa (HS) is a systemic disorder associated with various metabolic and inflammatory comorbidities. Although HS shares risk factors and pathogenic pathways with various respiratory conditions, few studies have explored the relationship between HS and respiratory disease. This is a cross-sectional, case-control, population-based study that examined the United States National Inpatient Sample database from January 1, 2002, to December 31, 2012. HS was identified using ICD-9-CM codes during hospital admissions. Multivariable logistic regression was used to evaluate for adjusted associations between HS and respiratory diagnoses as compared to matched controls. Twenty-three thousand seven hundred and sixty-seven hospital admissions for HS were compared with 95,068 age- and sex-matched controls. HS patients had significantly higher adjusted odds of asthma (OR: 1.233; 95% CI: [1.170-1.299]; P < 0.001), chronic airway obstruction (OR: 1.532; 95% CI: [1.419-1.651]; P < 0.001), sarcoidosis (OR: 1.601; 95% CI: [1.157-2.214]; P < 0.001), and sleep apnea (OR: 1.274; 95% CI: [1.182-1.374]; P < 0.001). HS is associated with several common forms of respiratory disease. Knowledge of these associations may allow for better recognition of respiratory disease in HS patients.

Functional analysis, diversity, and distribution of the ean cluster responsible for 17β-estradiol degradation in sphingomonads.

17β-estradiol (E2) is a natural endocrine disruptor that is frequently detected in surface and groundwater sources, thereby threatening ecosystems and human health. The newly isolated E2-degrading strain Sphingomonas colocasiae C3-2 can degrade E2 through both the 4,5-seco pathway and the 9,10-seco pathway; the former is the primary pathway supporting the growth of this strain and the latter is a branching pathway. The novel gene cluster ean was found to be responsible for E2 degradation through the 4,5-seco pathway, where E2 is converted to estrone (E1) by EanA, which belongs to the short-chain dehydrogenases/reductases (SDR) superfamily. A three-component oxygenase system (including the P450 monooxygenase EanB1, the small iron-sulfur protein ferredoxin EanB2, and the ferredoxin reductase EanB3) was responsible for hydroxylating E1 to 4-hydroxyestrone (4-OH-E1). The enzymatic assay showed that the proportion of the three components is critical for its function. The dioxygenase EanC catalyzes ring A cleavage of 4-OH-E1, and the oxidoreductase EanD is responsible for the decarboxylation of the ring A-cleavage product of 4-OH-E1. EanR, a TetR family transcriptional regulator, acts as a transcriptional repressor of the ean cluster. The ean cluster was also found in other reported E2-degrading sphingomonads. In addition, the novel two-component monooxygenase EanE1E2 can open ring B of 4-OH-E1 via the 9,10-seco pathway, but its encoding genes are not located within the ean cluster. These results refine research on genes involved in E2 degradation and enrich the understanding of the cleavages of ring A and ring B of E2.IMPORTANCESteroid estrogens have been detected in diverse environments, ranging from oceans and rivers to soils and groundwater, posing serious risks to both human health and ecological safety. The United States National Toxicology Program and the World Health Organization have both classified estrogens as Group 1 carcinogens. Several model organisms (proteobacteria) have established the 4,5-seco pathway for estrogen degradation. In this study, the newly isolated Sphingomonas colocasiae C3-2 could degrade E2 through both the 4,5-seco pathway and the 9,10-seco pathway. The novel gene cluster ean (including eanA, eanB1, eanC, and eanD) responsible for E2 degradation by the 4,5-seco pathway was identified; the novel two-component monooxygenase EanE1E2 can open ring B of 4-OH-E1 through the 9,10-seco pathway. The TetR family transcriptional regulator EanR acts as a transcriptional repressor of the ean cluster. The cluster ean was also found to be present in other reported E2-degrading sphingomonads, indicating the ubiquity of the E2 metabolism in the environment.

Trends in prevalence of hearing loss in adults in the USA 1999-2018: a cross-sectional study.

A better understanding of how the prevalence of hearing loss and its associated factors change over time could help in developing an appropriate program to prevent the development of hearing loss. Population-representative cross-sectional data from the United States National Health and Nutrition Examination Survey (NHANES) were used to estimate the trends in the prevalence of hearing loss among adults in the USA over the period 1999-2018. A total of 15,498 adult participants aged 20years or older had complete audiometric examination data. Logistic regression was employed to evaluate the trend in hearing loss; weighted Rao-Scott χ2 tests and univariate logistic regression analyses were used to examine the association between hearing loss and relevant factors. The overall hearing loss prevalence in 1999-2018 was 19.1% 19.1 (95% CI, 18.0-20.2%). The prevalence of hearing loss decreased in cycles (P for trend < 0.001). For participants aged 20-69years, the prevalence decreased from 15.6% (95% CI, 12.9-18.4%) in 1999-2000 to 14.9% (95% CI, 13.2- 16.6%) in 2015-2016; for participants aged > 70years the prevalence decreased from 79.9% (95% CI, 76.1-83.8%) in 2005-2006 to 64.5% (95% CI, 58.8-70.2%) in 2017-2018. Participants with hearing loss were likely to be older, male, non-Hispanic white, and to have not completed high school. Mild hearing loss was more prevalent among those aged 20-79years; in those aged over 80years the prevalence of moderate hearing loss exceeded that of mild loss. Among all otologically normal participants, hearing thresholds increased with age across the entire frequency range. The prevalence of hearing loss in USA adults changed over the period 1999-2018. The trends observed provide valuable insight for making public health plans and allocating resources to hearing care. Further investigation is necessary to monitor hearing loss and its potential risk factors.

Pediatric neurosurgical medulloblastoma outcomes in La Paz, Bolivia: How a Lower Middle-Income Country (LMIC) institution in South America compares to the United States.

How pediatric medulloblastoma patients fare in Lower Middle-Income Country (LMICs) in South America is not well understood. Correspondingly, the aim of this study was to summarize the pediatric neurosurgical experience of an institution in La Paz, and compare outcomes to that of a generalized High Income Country (HIC) United States (US) experience. A retrospective review of all pediatric neurosurgical medulloblastoma patients at the Children's Hospital of La Paz, Bolivia (Hospital del Niño "Dr. Ovidio Aliaga Uria") between 2014 and 2023 was conducted and compared to a generalized US experience abstracted from the US National Cancer Database (NCDB) and National Inpatient Sample (NIS) databases. Categorical, continuous and survival data were statistically summarized and compared. A total of 24 pediatric medulloblastoma patients underwent neurosurgical treatment at the Hospital del Niño. In this La Paz cohort, there were 15 (63%) males and 9 (38%) females, with a mean age of 5.6 years old at diagnosis. The majority of patients underwent subtotal resection (STR, 79%), while the remaining patients underwent biopsy only. Ten (42%) patients expired during their hospitalization, and mean length of stay overall was 39 days. Only 8 (33%) patients received adjuvant treatment after surgery. Median overall survival from diagnosis in the La Paz cohort was 1.9 months. Compared to the US databases, the La Paz cohort experienced significantly more emergency room admissions for surgery, less gross total resection, more STR, more return to operating room for ventriculoperitoneal shunting, more bacteremia, more tracheostomy procedures, more percutaneous gastrostomy placements, longer lengths of stay, less adjuvant chemotherapy, less radiation therapy, shorter follow-up, and ultimately, significantly shorter overall survival (all P < 0.050). Pediatric neurosurgical medulloblastoma outcomes at the Children's Hospital of La Paz, Bolivia are significantly inferior to that of a generalized US experience. Future research is required to identify institution- and country-specific initiatives to improve discrepancies between institutions in LMICs in South America compared to HICs.

Associations of seven measures of biological age acceleration with frailty and all-cause mortality among adult survivors of childhood cancer in the St. Jude Lifetime Cohort.

Survivors of childhood cancer may experience accelerated biological aging, resulting in premature frailty and death. We used seven measures of biological age in the St. Jude Lifetime (SJLIFE) Cohort to compare biological age acceleration between the SJLIFE Cohort and the third United States National Health and Nutrition Examination Survey controls, explore trajectories of biological age according to cancer treatment and type, and test associations of biological age acceleration with frailty and death (mean follow-up of 26.5 years) among survivors. Survivors of cancer aged 5% faster per year and measured, on average, 0.6-6.44 years biologically older compared to controls and 5-16 years biologically older compared to age-matched individuals at the population level. Survivors treated with hematopoietic cell transplant and vinca alkaloid chemotherapy evidenced the fastest trajectories of biological aging. Biologically, older and faster-aging survivors consistently and robustly had a higher risk of frailty and died earlier than those with slower biological aging, suggesting a potential opportunity to intervene on excess aging.

The demand for male contraception: Estimating the potential market for users of novel male contraceptive methods using United States National Survey of Family Growth data

ObjectiveTo estimate the potential market for novel male contraceptives (NMCs) using United States National Survey of Family Growth (NSFG) data, 2015–2017. Study designWe described the market for NMCs via secondary analysis of the 2015–2017 NSFG’s weighted male respondent data, utilizing surrogate markers for contraceptive switching (NSFG) and contraceptive discontinuation data from the Contraceptive CHOICE project. Potential NMC users included men relying on: (1) no methods or less effective methods but who reported that they would be “very upset” if they got someone pregnant, (2) permanent methods but who reported that they might still want more children, (3) a female partner’s method that she might discontinue in the next year, (4) a male method even when his partner uses her own contraceptive. ResultsOf 3340 respondents—representing 55,890,830 sexually active, reproductive-age men—23.2% used no contraception at last intercourse, 15.8% condoms, 5.1% withdrawal, and 5.1% vasectomy. Among respondents relying solely on condoms, withdrawal, or no method, 19.7%, 3.8%, and 4.4% would be “very upset” if they got someone pregnant. For permanent contraceptive users, 17.3%−20.5% wanted another child. For men reliant on their partner’s long-acting reversible or combined hormonal contraceptive, 12–17% and 45–51% of partners might discontinue their method. These data conservatively suggest that 13% or more than 7 million men would potentially use NMCs, rising to 15.5 million with less restrictive contraceptive switching criteria. ConclusionAdjusting for pregnancy attitudes and likelihood of contraceptive switching, a substantial portion (between 7–15.5 million) of reproductive age men in the US are potential NMC users. ImplicationsThe population of potential novel male contraceptive users extends beyond just users of condoms, withdrawal and vasectomy and should include couples practicing dual-partner contraception and female partners using contraceptive methods that they may become dissatisfied with and discontinue.

Social Determinants Associated with Substance Use and Treatment Seeking in Females of Reproductive Age in the United States.

Introduction: Females of reproductive age (FoRA; 15-49 years) are the demographic most likely to be diagnosed with a substance use disorder. Preventative treatment prior to or during pregnancy is critical. Stigma and social inequities can delay access to care. There is limited research examining social determinants of health (SDoH) and how they are related to substance use and treatment seeking in this demographic. Methods: We analyzed the 2016-2019 data from the United States National Survey on Drug Use and Health using multivariable logistic regression models. Statistically significant variables were conceptually linked to the Office of Disease Prevention and Health Promotion's (ODPHP's) SDoH framework's five domains. Results: From a total sample of 1,477,336 (weighted) pregnant people and 39,600,523 (weighted) FoRA, substance use was reported by 879,209 (2.14% [95% confidence interval = 2.13-2.15]). Pregnancy status was not associated with substance use or treatment seeking. Past-month substance use was associated with high educational attainment, an annual income <$20,000, a history of criminality, low religiosity, and having health insurance. Past-month treatment-seeking behavior was associated with older age, an annual income >$20,000, a history of criminality, and greater religiosity. Behavioral health support seeking in the past month was associated with some college education. Higher depression severity was associated with all the three models. Conclusions: Using the ODPHP's SDoH framework, we begin to elicit critical connections that can describe substance use and treatment-seeking practices in FoRA. We encourage additional research to inform public health, health care, behavioral health, and other support service programming.

Gray whale (Eschrichtius robustus) post-mortem findings from December 2018 through 2021 during the Unusual Mortality Event in the Eastern North Pacific.

Beginning in December 2018, increased numbers of gray whale (Eschrichtius robustus) strandings were reported along the west coast of Mexico, the United States, and Canada, prompting declaration of a gray whale Unusual Mortality Event (UME) by the United States National Marine Fisheries Service. Although strandings declined in 2020 and 2021 from a peak in 2019, the UME is still ongoing as of fall 2023. Between 17 December 2018 and 31 December 2021, 503 animals stranded along the west coast of North America, with 226 strandings in Mexico, 71 in California, 12 in Oregon, 56 in Washington, 21 in British Columbia, and 117 in Alaska. These included 187 males, 167 females, and 149 whales of undetermined sex; and 193 adults, 194 subadults, 40 calves, 1 fetus, and 75 whales of undetermined age class. We report on 61 of the 503 carcasses (12%) that had external and internal gross necropsy and/or histopathology data: of these 61 whales, findings that contributed to death were identified in 33 (54%) whales. Sixteen of the 61 (26%) were severely emaciated. Gross lesions of blunt force trauma consistent with vessel strike were identified in 11 of the 61 animals (18%), only two of which were emaciated. Two whales (3%) were entangled at time of death, and one died from entrapment. Signs of killer whale (Orcinus orca) interaction were documented in 19 of the 61 animals; five were deemed from recent interactions and three (5%) likely contributed to mortality. A specific cause of death could not be identified in 28 of 61 whales (46%). Additionally, logistical challenges and the advanced state of decomposition of most examined carcasses precluded detection of potential infectious or toxic causes of morbidity or mortality. Up to 2016, the eastern North Pacific population of gray whale population had generally been increasing since the cessation of historic whaling and a prior UME in 1999-2000. However, recent abundance and calf production estimates have declined, a trend that overlaps the current UME. The relative contributions of carrying capacity, environmental change, prey shifts, and infectious, toxic, and other processes to the increased gray whale mortalities have not yet been resolved. Nevertheless, the marked temporal increase in strandings, including findings of malnutrition in some of the whales, along with low calf production, likely represent consequences of complex and dynamic ecological interactions in the ocean impacting the population.

Site-specific patterns of early-stage cancer diagnosis during the COVID-19 pandemic.

The COVID-19 pandemic caused widespread disruptions in cancer care. We hypothesized that the greatest disruptions in diagnosis occurred in screen-detected cancers. We identified patients (≥18 years of age) with newly diagnosed cancer from 2019 to 2020 in the US National Cancer Database and calculated the change in proportion of early-stage to late-stage cancers using a weighted linear regression. Disruptions in early-stage diagnosis were greater than in late-stage diagnosis (17% vs 12.5%). Melanoma demonstrated the greatest relative decrease in early-stage vs late-stage diagnosis (22.9% vs 9.2%), whereas the decrease was similar for pancreatic cancer. Compared with breast cancer, cervical, melanoma, prostate, colorectal, and lung cancers showed the greatest disruptions in early-stage diagnosis. Uninsured patients experienced greater disruptions than privately insured patients. Disruptions in cancer diagnosis in 2020 had a larger impact on early-stage disease, particularly screen-detected cancers. Our study supports emerging evidence that primary care visits may play a critical role in early melanoma detection.

Peers plus mobile app for treatment in HIV (PATH): protocol for a randomized controlled trial to test a community-based integrated peer support and mHealth intervention to improve viral suppression among Hispanic and Black people living with HIV

BackgroundSignificant disparities continue to exist in the HIV care continuum, whereby Hispanic and Black people living with HIV (PLWH) are less likely to achieve viral suppression compared to their White counterparts. Studies have shown that intervention approaches that involve peer navigation may play an important role in supporting patients to stay engaged in HIV care. However, implementation may be challenging in real-world settings where there are limited resources to support peer navigators. Combining a peer navigation approach with scalable mobile health (mHealth) technology may improve impact and implementation outcomes.MethodsWe combined a peer navigation intervention with a mHealth application and are conducting a randomized controlled trial (RCT) to test the efficacy of this integrated “Peers plus mobile App for Treatment in HIV” (PATH) intervention to improve HIV care engagement, and ultimately sustained viral suppression, among Hispanic and Black PLWH. We will enroll up to 375 PLWH into a two-arm prospective RCT, conducting follow-up assessments every 3 months up to 12 months post-baseline. Participants randomized to the control arm will continue to receive usual care Ryan White Program case management services. Individuals randomized to receive the PATH intervention will receive usual care plus access to two main intervention components: (1) a peer navigation program and (2) a mHealth web application. The primary outcome is sustained HIV viral suppression (undetectable viral load observed at 6- and 12-month follow-up). Secondary outcomes are retention in HIV care, gaps in HIV medical visits, and self-reported ART adherence. Recruitment for the RCT began in November 2021 and will continue until June 2024. Follow-up assessments and medical chart abstractions will be conducted to collect measurements of outcome variables.DiscussionThe efficacy trial of PATH will help to fill gaps in our scientific understanding of how a combined peer navigation and mHealth approach may produce effects on HIV care outcomes while addressing potential implementation challenges of peer navigation in Ryan White-funded clinics.Trial registrationThe PATH trial is registered at the United States National Institutes of Health National Library of Medicine (ClinicalTrials.gov) under ID # NCT05427318. Registered on 22 June 2022.

Prevalence and secular trends in premetabolic syndrome in the United States: Findings from 1999-2020 nationally representative data of adults

PurposeAlthough Premetabolic syndrome (PeMetSyn) is a precursor for metabolic syndrome (MetSyn), its prevalence and trends are unknown. This study examined the prevalence and trends in PreMetSyn and its association with sociodemographic risk factors in American adults. MethodsThe 1999–2000 to 2017–2020 United States National Health and Nutritional Health Surveys (NHANES) data were used. PreMetSyn was defined as co-occurrence two cardiometabolic risk factors consisting of abdominal obesity, elevated triglycerides, reduced HDL-C, elevated blood pressure, and fasting plasma glucose. We calculated sex-specific overall prevalence of PreMetSyn and by race/ethnicity, age, education, poverty, and body mass index (BMI) categories. Sex-specific logistic regression models were used to test the association between sociodemographic risk factors and PreMetSyn. ResultsFrom 1999 − 2000 to 2017–2020, the age-adjusted overall prevalence of PreMetSyn increased by 155.4% (from 9.2% to 23.5%) in men and by 131.3% (from 11.2% to 25.9%) in women. Increases in prevalence of PreMetSyn were observed by race/ethnicity, age, education, poverty and BMI levels in men and women from 1999–2000 to 2017–2020. Survey cycle, race/ethnicity, age, education, poverty-income ratio, and BMI were independently associated with greater odds of PreMetSyn in males and females. During this period, the co-occurrence of abdominal obesity and elevated blood pressure was the most common comorbidity and increased from 20.6% to 30.8% in men and from 27.8% to 36.1% in women. ConclusionsThis nationally representative study indicates a rapid increase from 1999–2000 to 2017–2020 in the proportion of American adults who meet the criteria for PreMetSyn. Early identification of subjects with PreMetSyn in the U.S. is a public health priority for initiating effective strategies to prevent the development of MetSyn and its associated chronic diseases.

Sugar-sweetened beverage intake and long-term mortality in individuals with metabolic dysfunction-associated steatotic liver disease: a longitudinal analysis of the National Health and Nutrition Examination Survey database.

Consuming sugar-sweetened beverages (SSBs) has been linked to the development of various adverse health conditions, including metabolic dysfunction-associated steatotic liver disease (MASLD). This study evaluated associations between SSB intake and long-term mortality among individuals with MASLD using a nationally representative database. This population-based, longitudinal study extracted data of adults aged 20-79 years with MASLD from the USA (US) National Health and Nutrition Examination Survey database 2003-2014. Associations between the amount of SSB intake and all-cause, cancer and cardiovascular disease mortality until the end of 2019 were determined using Cox proportional hazards regression analyses. A total of 12 965 individuals aged 20-79 years who had MASLD were identified in the database. After exclusion, 5630 participants remained for the analyses. This cohort can be extrapolated to 43 420 321 individuals in the entire US after proper weighting. The mean age of the study cohort was 44.1 years. After adjusting for confounders, no significant association was observed between SSB intake (tertile 3 vs. tertile 1) and all-cause [adjusted hazard ratio (aHR): 1.03, 95% confidence interval (CI), 0.60-1.76) or cancer mortality (aHR, 0.41; 95% CI, 0.15-1.16). However, higher SSB intake (tertile 3 vs. tertile 1) was significantly associated with elevated cardiovascular disease mortality risk (aHR = 2.83; 95% CI, 1.01-7.91). In US adults with MASLD, high SSB intake is associated with nearly three-fold increased cardiovascular disease mortality risk. The findings underscore the critical need for concerted action on the part of healthcare providers and policymakers.
