Artificial intelligence-based epigenomic, transcriptomic and histologic signatures of tobacco use in oral squamous cell carcinoma.

Oral squamous cell carcinoma (OSCC) biomarker studies rarely employ multi-omic biomarker strategies and pertinent clinicopathologic characteristics to predict mortality. In this study we determine for the first time a combined epigenetic, gene expression, and histology signature that differentiates between patients with different tobacco use history (heavy tobacco use with ≥10 pack years vs. no tobacco use). Using The Cancer Genome Atlas (TCGA) cohort (n = 257) and an internal cohort (n = 40), we identify 3 epigenetic markers (GPR15, GNG12, GDNF) and 13 expression markers (IGHA2, SCG5, RPL3L, NTRK1, CD96, BMP6, TFPI2, EFEMP2, RYR3, DMTN, GPD2, BAALC, and FMO3), which are dysregulated in OSCC patients who were never smokers vs. those who have a ≥ 10 pack year history. While mortality risk prediction based on smoking status and clinicopathologic covariates alone is inaccurate (c-statistic = 0.57), the combined epigenetic/expression and histologic signature has a c-statistic = 0.9409 in predicting 5-year mortality in OSCC patients.

Future patterns in burden and incidence of squamous cell carcinoma of the anus in the United States, 2001-2035.

Squamous cell carcinoma of the anus (SCCA) incidence has been rising in the United States, particularly among older adults (≥65 years). We estimated the impact of this rise on future burden (through 2035) using age-period-cohort modeling. The SCCA burden (cases/year) is expected to rise, reaching ∼2700 among men and ∼7000 among women in 2031-2035 (burden during 2016-2020 among men and women was ∼2150 and ∼4600), with most cases aged ≥65 years (61% in men and 70% in women in 2031-2035; from 40% and 46% in 2016-2020). SCCA incidence (per 100,000) is projected to rise among older men aged 65-74, 75-84, and ≥85 years (5.0, 4.9, and 4.3, in 2031-2035 vs 3.7, 3.8, 3.4 in 2016-2020) and women (11.2, 12.6, 8.0 in 2031-2035 vs 8.2, 6.8, 5.2 in 2016-2020). The projected rise in SCCA burden among older adults is troubling and highlights the importance of improving early detection and clinical care.

Fabrication of acetazolamide loaded leciplex for intraocular delivery: Optimization by 32 full factorial design, in vitro, ex vivo and in vivo pharmacodynamics.

The complex structure of the eye poses challenges in delivering drugs effectively, which can be circumvented by employing nanotechnologies. The present study aimed to prepareacetazolamide-loadedleciplex (ACZ - LP) using a simple one-step fabrication approach followed byoptimization employing a 32 Full Factorial Design. The ACZ - LP demonstrated high entrapment efficiency (93.25 ± 2.32 %), average diameter was recorded around 171.03 ± 3.32 with monodisperse size distribution and zeta potential of 41.33 ± 2.10 mV. Invitro release and ex vivo permeation studies of prepared formulation demonstrated an initial burst release in 1 h followed by sustained release pattern as compared to plain acetazolamide solution. Moreover, an ex vivo corneal drug retention (27.05 ± 1.20 %) and in vitro mucoadhesive studies with different concentration of mucin indicated strong electrostatic bonding confirming the mucoadhesive characteristics of the formulation. Additionally, the histopathological studies ensured that the formulation was non-irritant and nontoxic while and HET-CAM ensured substantial tolerability of the formulation. The in vivo pharmacodynamic investigation carried out on a rabbit model demonstrated that treatment with ACZ - LP resulted in a significant and prolonged reduction in intraocular pressure as compared to plain acetazolamide solution, acetazolamide oral tablet, and Brinzox®. In summary, the ACZ - LP is anefficient and versatile drug delivery approach which demonstrates significant potential in controlling glaucoma.

Recent and projected incidence trends and risk of anal cancer among people with HIV in North america.

BACKGROUND: Anal cancer risk is elevated among people with HIV (PWH). Recent anal cancer incidence patterns among PWH in the United States (US) and Canada remain unclear. It is unknown how the incidence patterns may evolve in future years. METHODS: Using data from the North American AIDS Cohort Collaboration on Research and Design, we investigated absolute anal cancer incidence and incidence trends in the US, Canada, and different US regions. We further estimated relative risk compared with persons without HIV, relative risk among various subgroups, and projected future anal cancer burden among US PWH. RESULTS: During 2001-2016, in the US, age-standardized anal cancer incidence declined 2.2%/year (95%CI=-4.4% to -0.1%), particularly in the Western region (-3.8%/year [95%CI=-6.5% to -0.9%]. In Canada, incidence remained stable. Considerable geographic variation in risk was observed by US regions (eg, over four-fold risk in the Midwest and Southeast compared to the Northeast among men who have sex with men [MSM] with HIV). Anal cancer risk increased with a decrease in nadir CD4 count and was elevated among those with opportunistic illnesses. Anal cancer burden among US PWH is expected to decrease in future years (through 2035), but >70% of cases will continue to occur in MSM with HIV and people with AIDS. CONCLUSION: Geographic variation in anal cancer risk and trends may reflect underlying differences in screening practices and HIV epidemic. MSM with HIV and PWH with AIDS will continue to bear most anal cancer burden, highlighting the importance of precision prevention.

National Breast, Cervical, and Colorectal Cancer Screening Use in Federally Qualified Health Centers.

Importance: Federally qualified health centers (FQHCs) deliver health care to nearly 30 million underserved persons across the US, yet nationwide and state-level breast, cervical, and colorectal cancer screening use in FQHCs is not described. Furthermore, it is unknown how the underscreened FQHC population contributes to the total underscreened population at national and state levels. Objective: To describe national- and state-level breast, cervical, and colorectal cancer screening use among individuals served by FQHCs in the US and to estimate the percentage of underscreened individuals in the general population served by FQHCs. Design, Setting, and Participants: This cross-sectional analysis of cancer screening used data from January 1 through December 31, 2020, from the FQHC Uniform Data System, reported by 1364 FQHCs across the US, and self-reported estimates from the Behavioral Risk Factor Surveillance System. Participants were 16 696 692 US adults served by FQHCs who were eligible for breast (age, 50-74 years), cervical (age, 21-64 years), and colorectal (age, 50-75 years) cancer screening. Analyses were conducted between January 1 and June 30, 2023. Exposures: Breast, cervical, and colorectal cancer screening. Main Outcomes and Measures: Percentages of breast, cervical, and colorectal cancer screening-eligible individuals up to date on screening. Results: A total of 3 162 882 breast, 7 444 465 cervical, and 6 089 345 colorectal screening-eligible individuals were served by FQHCs in 2020. Nationally, screening use in FQHCs was 45.4% (95% CI, 45.4%-45.5%) for breast cancer, 51.0% (95% CI, 51.0%-51.1%) for cervical cancer, and 40.2% (95% CI, 40.1%-40.2%) for colorectal cancer. Screening use among the US general population was 78.2% (95% CI, 77.6%-78.9%) for breast cancer, 82.9% (95% CI, 82.3%-83.4%) for cervical cancer, and 72.3% (95% CI, 71.7%-72.8%) for colorectal cancer. The contribution of the underscreened population served by FQHCs to the national underscreened general population was 16.9% (95% uncertainty interval [UI], 16.4%-17.4%) for breast cancer, 29.7% (95% UI, 28.8%-30.7%) for cervical cancer, and 14.7% (95% UI, 14.4%-15.0%) for colorectal cancer. Conclusions and Relevance: Findings from this national cross-sectional study indicated major gaps in cancer screening use in FQHCs in the US. Improved prevention is urgently needed to address screening disparities.

Valorization of sugarcane bagasse for high-yield production of laccase through Aspergillus terreus for effective azo dye decolourization.

Synthetic dyes such as azo dyes are significant pollutants in the wastewater released from various textile industries. The low biodegradability and production from synthetic sources with high shelf life make azo dyes a challenging material for degradation. This study used chemically mutated Aspergillus terrus in the laccase production under solid-state fermentation using sugarcane bagasse. Initially, the wild-type strain produced a laccase activity of 4.12 U/mL. Later, the alkaline pretreatment of sugarcane bagasse showed a significant increase in laccase activity by 38.9%. Further, random mutagenesis treatment with 100 mM EMS generated a hyper laccase-producing strain with a 2.3-fold increment in laccase activity compared to the wild-type strain. The enzyme displayed optimal activity at pH 6.5 and 35 °C. The metal ions such as Fe3+ (29.4 U/mL), Fe2+ (20.8 U/mL) and Cu2+ (18.05 U/mL) showed positive effects on laccase activity. The crude laccase was used to bioremediate Congo red, a prominent azo dye used in textile and pharmaceutical industries. The preliminary studies with a crude enzyme displayed 68.86% dye decolourization after 24 h of incubation. Additionally, with Taguchi orthogonal array optimization experiments, the maximal dye decolorization of 78.24% was achieved by maintaining crude enzyme concentration (20 U), dye concentration (25 mg/L) and pH 4.5.

Trends in Oral Tongue Cancer Incidence in the US.

Importance: Oral tongue cancer (OTC) incidence has increased rapidly among young (<50 years) non-Hispanic White individuals in the US during the past 2 decades; however, it is unknown if age-associated trajectories have persisted. Objective: To examine US trends in OTC incidence and project future case burden. Design, Setting, and Participants: This cross-sectional analysis of OTC incidence trends used the US Cancer Statistics Public Use Database, which covers approximately 98% of the US population, and included individuals with an OTC diagnosis reported to US cancer registries between January 1, 2001, and December 31, 2019. Exposures: Sex, race and ethnicity, and age. Main Outcomes and Measures: Estimated average annual percentage change in OTC incidence from 2001 to 2019. Given the substantial incidence rate increases among non-Hispanic White individuals compared with those of racial and ethnic minority groups, subsequent analyses were restricted to non-Hispanic White individuals. Forecasted OTC incidence trends and case burden among non-Hispanic White individuals to 2034. Results: There were 58 661 new cases of OTC identified between 2001 and 2019. Male individuals (57.6%), non-Hispanic White individuals (83.7%), those aged 60 years or older (58.0%), and individuals with localized stage disease at diagnosis (62.7%) comprised most cases. OTC incidence increased across all age, sex, and racial and ethnic groups, with marked increases observed among non-Hispanic White individuals (2.9% per year; 95% CI, 2.2%-3.7%). Increases among female individuals aged 50 to 59 years were most notable and significantly outpaced increases among younger non-Hispanic White female individuals (4.8% per year [95% CI, 4.1%-5.4%] vs 3.3% per year [95% CI, 2.7%-3.8%]). While all non-Hispanic White birth cohorts from 1925 to 1980 saw sustained increases, rates stabilized among female individuals born after 1980. Should trends continue, the burden of new OTC cases among non-Hispanic White individuals in the US is projected to shift more toward older individuals (from 33.1% to 49.3% among individuals aged 70 years or older) and female individuals (86% case increase vs 62% among male individuals). Conclusions and Relevance: The results of this cross-sectional study suggest that the period of rapidly increasing OTC incidence among younger non-Hispanic White female individuals in the US is tempering and giving way to greater increases among older female individuals, suggesting a birth cohort effect may have been associated with previously observed trends. Recent increases among non-Hispanic White individuals 50 years or older of both sexes have matched or outpaced younger age groups. Continuing increases among older individuals, particularly female individuals, may be associated with a shift in the OTC patient profile over time.

Sustainable biorefinery approach by utilizing xylose fraction of lignocellulosic biomass.

Lignocellulosic biomass (LCB) has been a lucrative feedstock for developing biochemical products due to its rich organic content, low carbon footprint and abundant accessibility. The recalcitrant nature of this feedstock is a foremost bottleneck. It needs suitable pretreatment techniques to achieve a high yield of sugar fractions such as glucose and xylose with low inhibitory components. Cellulosic sugars are commonly used for the bio-manufacturing process, and the xylose sugar, which is predominant in the hemicellulosic fraction, is rejected as most cell factories lack the five­carbon metabolic pathways. In the present review, more emphasis was placed on the efficient pretreatment techniques developed for disintegrating LCB and enhancing xylose sugars. Further, the transformation of the xylose to value-added products through chemo-catalytic routes was highlighted. In addition, the review also recapitulates the sustainable production of biochemicals by native xylose assimilating microbes and engineering the metabolic pathway to ameliorate biomanufacturing using xylose as the sole carbon source. Overall, this review will give an edge on the bioprocessing of microbial metabolism for the efficient utilization of xylose in the LCB.

Enhancing Volleyball Athlete Performance: A Comprehensive Review of Training Interventions and Their Impact on Agility, Explosive Power, and Strength.

Volleyball is one of the most globally renowned sports in terms of global popularity. The game is a team sport that both men and women can participate in. The gameplay relies heavily on physical activities such as jumping, landing, and quick movements, often causing strain on the musculoskeletal system and leading to injuries. For this reason, agility training is crucial to improving a player's ability to change direction swiftly as and when required by the gameplay. Although it is relatively safer than other team sports, actions like jumping, blocking, and spiking can lead to potential injuries. Properly monitoring the training loads and injury prevention during training should be the major focus in formulating a holistic training methodology in volleyball training. The main goal of this literature study is to evaluate the impact of various training interventions on agility and other performance parameters specific to volleyball players. The range of research approaches and interventions described in this literature review highlights the significance of agility in volleyball training. In many studies, the use of tailored training programs for volleyball has been shown to have positive effects on agility, strength, and jump performance. Although there are limitations to the study design and sample size, the findings from this review necessitate the need for better scientifically informed training programs to reduce injury risk while enhancing player's overall performance potential. To conclude, the current literature review highlights the importance of agility training in volleyball, providing insights into effective training strategies and highlighting the low quality of evidence, suggesting the need for well-structured research on the topic.

Inter-atrial septal balloon dilation to facilitate intracardiac echocardiography guided left atrial appendage occlusion.

INTRODUCTION: Percutaneous left atrial appendage occlusion (LAAO) is traditionally performed under general anesthesia with trans-esophageal echocardiography guidance. Intracardiac echo (ICE)-guided LAAO closure is increasing in clinical use. The ICE catheter is crossed into LA via interatrial septum (IAS) after the septum is dilated with LAAO delivery sheath. This step can be time-consuming and requires significant ICE catheter manipulation, which increases the risk of cardiac perforation. Pre-emptive septal balloon dilation can potentially help with ICE advancement in the LA. We sought to evaluate the effect of pre-dilation of the IAS with an 8 mm balloon on the ease of crossing the ICE catheter, fluoroscopy time for crossing, and overall procedure time. METHODS: The Piedmont LAAO registry was used to identify consecutive patients who underwent LAAO. The initial 25 patients in whom balloon dilation of the IAS was performed served as the experimental cohort, and the 25 consecutive patients before that in whom balloon dilation was not performed served as controls. In the experimental group, after a trans-septal puncture, the sheath was retracted to the right atrium with a guidewire still in the LA. An 8 × 40 mm Evercoss™ over the wire balloon was inflated across the IAS. The ICE catheter was then crossed into the LA using the fluoroscopic landmark of the guide wire and the ICE imaging. The sheath was then advanced along the ICE catheter via the transseptal puncture (TSP) and the procedure continued. Follow-up compputed tomography imaging was obtained at 4-8 weeks. RESULTS: Each group consisted of 25 patients. There were no significant differences in baseline characteristics. All procedures were performed successfully under conscious sedation and ICE guidance. There was a significant reduction in the overall procedure time, fluoroscopy time, and time for transseptal puncture to ICE in LA. There was no difference in the size of the acute residual interatrial shunt, as measured via ICE, or the size and presence of iatrogenic ASD at follow-up. CONCLUSION: Balloon dilation of TSP is safe and is associated with increased efficiency in ICE-guided LAAO procedures.

Factors associated with parental human papillomavirus vaccination intentions among adolescents from socioeconomically advantaged versus deprived households: a nationwide, cross-sectional survey.

Background: In the USA, HPV vaccine coverage is substantially lower among adolescents from high-income households compared to their low-income counterparts. We examined and compared the factors associated with parental HPV vaccination intentions between socioeconomically divergent groups. Methods: Data from unvaccinated and not fully HPV-vaccinated adolescents from the 2017-2021 National Immunization Survey (NIS)-Teen were analyzed. Socioeconomically advantaged vs. deprived groups were identified based on dichotomized income (material capital) and education (social capital). Parental intent to initiate and complete the HPV vaccine series was compared using bivariable analysis and the factors associated with lacking intent were identified. Findings: The 2017-2021 NIS-Teen included a total of 212,643 participants; the final analytical sample consisted of 105,958 adolescents (an estimated 10.3 million adolescents) who were unvaccinated or not fully vaccinated. In the advantaged group, 64.7% of parents of unvaccinated adolescents (equating to 2.4 million US adolescents) had no intention to initiate the HPV vaccine compared to 40.9% of parents in the deprived group (equating to 0.2 million adolescents) (P < 0.0001; S > 13.29). The most frequent reason for lacking intent in the advantaged group was 'safety concerns' (25.5%). In the deprived group, 'lack of knowledge', 'not recommended', and 'not needed' were common reasons (nearly 15% each). Lack of intent to complete the HPV vaccine series was higher in the advantaged group (43.9%; 1.1 million adolescents) compared to the deprived group (25.2%; 0.08 million adolescents) (P < 0.0001; S > 13.29). More than half in the advantaged group (58.4%) and over a third (37.1%) in the deprived group cited 'already up to date' as the main reason for not completing the HPV vaccine series. Interpretation: Lack of intent to initiate and complete the HPV vaccination series, particularly among socioeconomically advantaged parents is a significant barrier to achieving the national goal in the USA.

The accuracy of anal self- and companion exams among sexual minority men and transgender women: a prospective analysis.

Background: Squamous cell carcinoma of the anus (SCCA) annual incidence among sexual minority men with and without HIV is 85/100,000 and 19/100,000 persons, respectively, which is significantly higher than the overall incidence (2/100,000). Incidence may also be higher in transgender women. Since SCCA tumours average ≥30 mm at diagnosis, we assessed the accuracy of individuals to self-detect smaller anal abnormalities. Methods: Using convenience sampling, the study enrolled sexual minority men and transgender women, aged 25-81 years, in Chicago, Illinois and Houston, Texas, USA, during 2020-2022. Individuals were taught the anal self-examination and anal companion examination (ASE/ACE). Then, a clinician performed a digital anal rectal examination (DARE) before participants conducted the ASE or ACE. The sensitivity, specificity and concordance of the ASE/ACE to detect an abnormality were measured along with factors associated with ASE/ACE and DARE concordance. Findings: Among 714 enrolled individuals, the median age was 40 years (interquartile range, 32-54), 36.8% (259/703) were living with HIV, and 47.0% (334/710), 23.4% (166/710), and 23.0% (163/710) were non-Hispanic white, non-Hispanic Black, and Hispanic, respectively. A total of 94.1% (671/713) identified as cisgendered men, and 5.9% (42/713) as gender minorities. A total of 658 participants completed an ASE and 28 couples (56 partners) completed an ACE. Clinicians detected abnormalities in 34.3% (245/714) of individuals. The abnormalities were a median of 3 mm in diameter. Sensitivity and specificity of the ASE/ACE was 59.6% (95% CI 53.5-65.7%) and 80.2% (95% CI 76.6-83.8%), respectively. Overall concordance was 0.73 (95% CI 0.70-0.76) between ASE/ACE and DARE and increased with increasing anal canal lesion size (p = 0.02). Concordance was lower when participants were older and received ASE/ACE training from a lay person rather than a clinician. Interpretation: Sexual minority men/transgender women may self-detect SCCA when malignant lesions are much smaller than the current mean dimension at presentation of ≥30 mm. Funding: National Cancer Institute.

Identification of authentic Phyllanthus amarus species in India.

The Phyllanthus is a plant used in the traditional Ayurvedic Medicine system and has more than 800 species. These species grow in the same area and there are chances of adulteration of other species and, incorrect identification may also lead to wrong reports. This study was attempted by Enovate Biolife Pvt. Ltd. to identify authentic Phyllanthus amarus. The nine raw material samples were collected from different populations/suppliers from various zones of India for the study. All the samples were analysed using microscopic and macroscopic ID, and by using the High Performance Thin Layer Chromatography (HPTLC) fingerprint method. The samples collected from the Central zone (Lucknow PA-08, Uttar Pradesh) and the Southern zone (Coimbatore PA-05, and Chennai PA-09, Tamil Nadu) of India were found to be authentic P. amarus by the mentioned identification methods.

Mixed food waste valorization using a thermostable glucoamylase enzyme produced by a newly isolated filamentous fungus: A sustainable biorefinery approach.

Food waste is a lucrative source of complex nutrients, which can be transformed into a multitude of bioproducts by the aid of microbial cell factories. The current study emphasizes isolating Glucoamylase enzyme (GA) producing strains that can effectively break down mixed food waste (MW), which serves as a substrate for biomanufacturing. The screening procedure relied heavily on the growth of isolated fungi on starch agar media, to specifically identify the microbes with the highest starch hydrolysis potential. A strain displayed the highest GA activity of 2.9 ± 0.14 U/ml which was selected and identified as Aspergillus fumigatus via molecular methods of identification. Exposure of the A. fumigatus with 200 mM Ethyl methanesulphonate (EMS) led to a 23.79% increase compared to the wild-type GA. The growth conditions like cultivation temperature or the number of spores in the inoculum were investigated. Further, maximum GA activity was exhibited at pH 5, 55 °C, and at 5 mM Ca2+ concentration. The GA showed thermostability, retaining activity even after long periods of exposure to temperatures as high as 95 °C. The improvement of hydrolysis of MW was achieved by Taguchi design where a maximum yield of 0.57 g g-1 glucose was obtained in the hydrolysate. This study puts forth the possibility that mixed food waste, despite containing spices and other microbial growth-inhibitory substances, can be efficiently hydrolyzed to release glucose units, by robust fungal cell factories. The glucose released can then be utilized as a carbon source for the production of value-added products.

Human Papillomavirus Vaccination Among Young Adults Before and During the COVID-19 Pandemic.

This cross-sectional survey study assesses the self-reported human papillomavirus vaccination rate by sociodemographic characteristics in adults aged 18 to 26 years from 2018 to 2022.

DDIT4L regulates mitochondrial and innate immune activities in early life.

Pattern recognition receptor responses are profoundly attenuated before the third trimester of gestation in the relatively low-oxygen human fetal environment. However, the mechanisms regulating these responses are uncharacterized. Herein, genome-wide transcription and functional metabolic experiments in primary neonatal monocytes linked the negative mTOR regulator DDIT4L to metabolic stress, cellular bioenergetics, and innate immune activity. Using genetically engineered monocytic U937 cells, we confirmed that DDIT4L overexpression altered mitochondrial dynamics, suppressing their activity, and blunted LPS-induced cytokine responses. We also showed that monocyte mitochondrial function is more restrictive in earlier gestation, resembling the phenotype of DDIT4L-overexpressing U937 cells. Gene expression analyses in neonatal granulocytes and lung macrophages in preterm infants confirmed upregulation of the DDIT4L gene in the early postnatal period and also suggested a potential protective role against inflammation-associated chronic neonatal lung disease. Taken together, these data show that DDIT4L regulates mitochondrial activity and provide what we believe to be the first direct evidence for its potential role supressing innate immune activity in myeloid cells during development.

Highly Ordered Eutectic Mesostructures via Template-Directed Solidification within Thermally Engineered Templates.

Template-directed self-assembly of solidifying eutectics results in emergence of unique microstructures due to diffusion constraints and thermal gradients imposed by the template. Here, the importance of selecting the template material based on its conductivity to control heat transfer between the template and the solidifying eutectic, and thus the thermal gradients near the solidification front, is demonstrated. Simulations elucidate the relationship between the thermal properties of the eutectic and template and the resultant microstructure. The overarching finding is that templates with low thermal conductivities are generally advantageous for forming highly organized microstructures. When electrochemically porosified silicon pillars (thermal conductivity < 0.3 Wm-1K-1) are used as the template into which an AgCl-KCl eutectic is solidified, 99% of the unit cells in the solidified structure exhibit the same pattern. In contrast, when higher thermal conductivity crystalline silicon pillars (≈100 Wm-1K-1) are utilized, the expected pattern is only present in 50% of the unit cells. The thermally engineered template results in mesostructures with tunable optical properties and reflectances nearly identical to the simulated reflectances of perfect structures, indicating highly ordered patterns are formed over large areas. This work highlights the importance of controlling heat flows in template-directed self-assembly of eutectics.

International Anal Neoplasia Society's consensus guidelines for anal cancer screening.

The International Anal Neoplasia Society (IANS) developed consensus guidelines to inform anal cancer screening use among various high-risk groups. Anal cancer incidence estimates by age among risk groups provided the basis to identify risk thresholds to recommend screening. Guided by risk thresholds, screening initiation at age 35 years was recommended for men who have sex with men (MSM) and transgender women (TW) with HIV. For other people with HIV and MSM and TW not with HIV, screening initiation at age 45 years was recommended. For solid organ transplant recipients, screening initiation beginning from 10 years post-transplant was recommended. For persons with a history of vulvar precancer or cancer, screening initiation was recommended starting within 1 year of diagnosis of vulvar precancer or cancer. Persons aged ≥45 years with a history of cervical/vaginal HSIL or cancer, perianal warts, persistent (>1 year) cervical HPV16, or autoimmune conditions could be considered for screening with shared decision-making, provided there is adequate capacity to perform diagnostic procedures (high-resolution anoscopy [HRA]). Anal cytology, high-risk (hr) human papillomavirus (HPV) testing (including genotyping for HPV16), and hrHPV-cytology co-testing are different strategies currently used for anal cancer screening that show acceptable performance. Thresholds for referral for HRA or follow-up screening tests are delineated. These recommendations from IANS provide the basis to inform management of abnormal screening results, considering currently available screening tools. These guidelines provide a pivotal foundation to help generate consensus among providers and inform the introduction and implementation of risk-targeted screening for anal cancer prevention.

Recent trends in cervical cancer incidence, stage at diagnosis, and mortality according to county-level income in the United States, 2000-2019.

Early evidence suggests that declining cervical cancer incidence reversed in low-income regions in the United States in recent years; however, it is unclear whether there are distinct patterns by race/ethnicity and stage at diagnosis and if the increase has translated into rising mortality. Using Surveillance, Epidemiology, and End Results data, we evaluated trends in hysterectomy-corrected cervical cancer incidence rates (2000-2019) and mortality rates (2005-2019) by county-level income and race/ethnicity, with further stratification of incidence by stage at diagnosis. Following a period of decline, hysterectomy-corrected cervical cancer incidence increased 1.0%/year (95% CI = 0.1% to 4.5%) among Non-Hispanic White women in low-income counties. Particularly, a statistically significant 4.4%/year (95% CI = 1.7% to 7.5%) increase in distant-stage cancer occurred in this group. Additionally, recent increases in cervical cancer mortality (1.1%/year [95% CI = -1.4% to 3.7%]) were observed among this group and Non-Hispanic Black women in low-income counties (2.9%/year [95% CI = -2.3% to 18.2%]), but trends were not statistically significant. Among Hispanic women in low-income counties, distant-stage cervical cancer incidence increased 1.5%/year (95% CI = -0.6% to 4.1%), albeit not statistically significant. The increasing incidence of distant-stage cervical cancer and mortality in specific racial/ethnic groups suggests that the recent introduction of higher sensitivity screening tests may not explain increasing trends in low-income counties. Our findings suggest that the observed rise in cervical cancer incidence may reflect disruptions along the screening and treatment continuum. Future research to further comprehend these trends and continued enhancements in prevention are crucial to combat rising cervical cancer incidence and mortality in low-income counties in the United States.
