OBJECTIVE: We sought to investigate the clinical determinants of intestinal failure and death in preterm infants with surgical NEC. METHODS: Retrospective comparison of clinical information between Group A = intestinal failure (Parenteral nutrition (PN) >90 days) and death and Group B = survivors and with PN dependence < 90 days in preterm infants with surgical NEC. RESULTS: Group A (n = 99/143) had a lower mean gestational age (26.4 weeks [SD3.5] vs. 29.4 [SD 3.5]; p = 0.013), lower birth weight (873 gm [SD 427g] vs. 1425 gm [894g]; p = <0.001), later age of NEC onset (22 days [SD20] vs. 16 days [SD 17]; p = 0.128), received surgery later (276 hours [SD 544] vs. 117 hours [SD 267]; p = 0.032), had cholestasis, received dopamine (80.6% vs. 58.5%; p = 0.010) more frequently and had longer postoperative ileus time (19.8 days [SD 15.4] vs. 11.8 days [SD 6.5]; p = <0.001) and reached full feeds later (93 days [SD 45] vs. 44 [SD 22]; p = <0.001) than Group B. On multivariate logistic regression, higher birth weight was associated with lower risk (OR 0.35, 95% CI 0.15–0.82; p = 0.016) of TPN > 90 days or death. Longer length of bowel resected (OR 1.76, 95% CI 1.02–3.02; p = 0.039) and longer postoperative ileus (OR 2.87, 95% CI 1.26–6.53; p = 0.011) were also independently associated with TPN >90days or death adjusted for gestational age and antenatal steroid treatment. CONCLUSION: In preterm infants with surgical NEC, clinical factors such as lower birth weight, longer bowel loss, and postoperative ileus days were significantly and independently associated with TPN >90 days or death.

OBJECTIVE: We sought to determine the clinical and histopathological factors associated with intestinal hemorrhage and its correlation with clinical outcomes in neonates with surgical necrotizing enterocolitis (NEC). METHODS: A retrospective study compared clinical and histopathology information in neonates following surgical NEC with severe hemorrhage and those with mild/moderate hemorrhagic lesions seen on resected intestine pathology. RESULTS: The infants with severe hemorrhage (Grade 3-4, 81/148, 54.7%) had significantly lower exposure to antenatal steroids (52.5 % vs 76.9 %; p = 0.004), had higher gestational age (28.5 weeks [7.14] vs. 26.58 [2.90]; p = 0.034), lost more bowel length (p = 0.045), had higher CRP levels at 2 weeks (p = 0.035), and had less intestinal failure ([30.3 % vs 52.5 %]; p = 0.014) than mild/moderate (Grade 0–2, 67/148, 45.2%) hemorrhage group. Those with severe hemorrhage had significantly higher mean inflammation score (2.67 [0.94] vs. 1.63 [0.92]; p = <0.001), higher necrosis scores (1.95 [1.28] vs. 1.49 [1.35]; p = 0.037), higher neovascularization (p = 0.01), higher fibroblasts (p = 0.023) and higher lymphocyte percentages up to 48 hours (p < 0.05) following NEC than mild/ moderate hemorrhage group. On multivariable regression, less exposure to antenatal steroids (OR 0.18 [95% CI 0.05–0.58]; p = 0.005), higher inflammation (OR 3.7 [95% CI 2.09–7.32]; p = 0.001), and lymphocyte count on the day of onset/24 hours following NEC (OR 1.06 [95% CI 1.02–1.11]; p = 0.005) were independently associated with a higher odd of severe intestinal hemorrhage. CONCLUSION: The surgical NEC infants with intestinal hemorrhage were less likely to have antenatal steroid exposure but had higher inflammation grade and lymphocyte counts following NEC onset on multivariable regression modeling.

BackgroundIndia began COVID-19 vaccination in January 2021, initially targeting healthcare and frontline workers. The vaccination strategy was expanded in a phased manner and currently covers all individuals aged 18 years and above. India experienced a severe second wave of COVID-19 during March-June 2021. We conducted a fourth nationwide serosurvey to estimate prevalence of SARS-CoV-2 antibodies in the general population aged ≥6 years and healthcare workers (HCWs).Methods and findingsWe did a cross-sectional study between 14 June and 6 July 2021 in the same 70 districts across 20 states and 1 union territory where 3 previous rounds of serosurveys were conducted. From each district, 10 clusters (villages in rural areas and wards in urban areas) were selected by the probability proportional to population size method. From each district, a minimum of 400 individuals aged ≥6 years from the general population (40 individuals from each cluster) and 100 HCWs from the district public health facilities were included. The serum samples were tested for the presence of IgG antibodies against S1-RBD and nucleocapsid protein of SARS-CoV-2 using chemiluminescence immunoassay. We estimated the weighted and test-adjusted seroprevalence of IgG antibodies against SARS-CoV-2, along with 95% CIs, based on the presence of antibodies to S1-RBD and/or nucleocapsid protein. Of the 28,975 individuals who participated in the survey, 2,892 (10%) were aged 6-9 years, 5,798 (20%) were aged 10-17 years, and 20,285 (70%) were aged ≥18 years; 15,160 (52.3%) participants were female, and 21,794 (75.2%) resided in rural areas. The weighted and test-adjusted prevalence of IgG antibodies against S1-RBD and/or nucleocapsid protein among the general population aged ≥6 years was 67.6% (95% CI 66.4% to 68.7%). Seroprevalence increased with age (p < 0.001) and was not different in rural and urban areas (p = 0.822). Compared to unvaccinated adults (62.3%, 95% CI 60.9% to 63.7%), seroprevalence was significantly higher among individuals who had received 1 vaccine dose (81.0%, 95% CI 79.6% to 82.3%, p < 0.001) and 2 vaccine doses (89.8%, 95% CI 88.4% to 91.1%, p < 0.001). The seroprevalence of IgG antibodies among 7,252 HCWs was 85.2% (95% CI 83.5% to 86.7%). Important limitations of the study include the survey design, which was aimed to estimate seroprevalence at the national level and not at a sub-national level, and the non-participation of 19% of eligible individuals in the survey.ConclusionsNearly two-thirds of individuals aged ≥6 years from the general population and 85% of HCWs had antibodies against SARS-CoV-2 by June-July 2021 in India. As one-third of the population is still seronegative, it is necessary to accelerate the coverage of COVID-19 vaccination among adults and continue adherence to non-pharmaceutical interventions.

Chromosome numbers are reported for 13 species and four artificially produced interspecific hybrids of Fuchsia (Onagraceae). The chromosome number of F. encliandra is reported here for the first time and new chromosome numbers were obtained for F. triphylla and F. boliviana. An approximately 2.4-fold variation in DNA C-value was observed with a range of values from 1.46 pg to 3.44 pg per 2C nucleus. The lowest C-values were found in the species from New Zealand. The four polyploidy species had considerably lower 1Cx-values than most of the diploid species. The nuclear DNA content of the hybrids was, as expected, intermediate between those of the parental species. [ABSTRACT FROM AUTHOR]

Cardiac embolism plays a very significant role in acute ischemic strokes (AIS), constituting approximately one-third of cases. The origin of these emboli often stems from intracardiac thrombi in the left atrium or left ventricle. Utilizing the National Readmission Database from 2016 to 2019, we investigate the prevalence of cardiac thrombi in AIS patients and explore their potential correlation with endovascular thrombectomy (EVT) utilization, and mortality rates. Among 1,272,456 AIS patients, 0.6% had concurrent cardiac thrombus, with an increasing trend observed over the study period (P value < 0.001). The cardiac thrombus cohort showed a higher prevalence of comorbidities such as congestive heart failure and atrial fibrillation. After propensity-score matching, groups were well-balanced in terms of baseline characteristics. Patients within the cardiac thrombus cohort experienced a longer hospital stay (median 5 days vs. 3 days), but no significant difference in mortality was noted. Importantly, the cardiac thrombus cohort demonstrated a higher frequency of EVT utilization, suggesting a link to larger vessel occlusions. Despite matching based on atrial fibrillation, the EVT utilization in the cardiac thrombus cohort remained high, highlighting a significant association. While 30-day readmission rates were comparable, cardiac thrombus patients faced a higher risk of gastrointestinal bleeding and hemorrhagic stroke, likely attributed to anticoagulation use. Limitations include potential miscoding in the administrative database and a lack of detailed imaging findings. In conclusion, this study highlights the increased likelihood of EVT in AIS patients with cardiac thrombus, possibly indicative of larger vessel occlusion associated with cardiac thrombus., (© 2024.

Introduction: Evidence suggests that advice from health care professionals (HCP) increases the likelihood of quit attempts and successful quitting of tobacco use. However, previous studies primarily focussed on cigarette smoking and did not include all forms of tobacco products. This study aimed to investigate the prevalence and disparities in receiving HCP's advice to quit tobacco use (combustible or noncombustible) in the US adult population., Methods: Using the 2022 National Health Information Survey (NHIS) data, we examined 4,424 adults who reported (i) any tobacco product use within the past 12 months and (ii) having seen an HCP within the past 12 months. The outcome variable included the receipt of advice to quit tobacco use from an HCP, and predictors included sociodemographic variables. Weighted prevalence estimates were calculated, and multivariable regression analyses were conducted., Results: Over 38% of tobacco users who visited an HCP were advised to quit. The odds of receiving such advice were lower among Hispanics (AOR: 0.625; 95% confidence interval (CI) [0.464-0.843]; p  = 0.002), males (AOR: 0.767; 95% CI [0.659-0.893], p  = 0.001), those above the poverty level (AOR: 0.795; 95% CI [0.641-0.987]; p  = 0.037), foreign-born (AOR: 0.664; 95% CI [0.496-0.888]; p  = 0.006), those with a bachelor's degree or higher educational level (AOR: 0.477; 95% CI [0.349-0.653]; p < 0.001) and those aged less than 45 years (AOR: 0.404; 95% CI: [0.344-0.473]; p  < 0.001)., Conclusion: The prevalence of receiving HCP's advice to quit tobacco use remains suboptimal and disparate among sociodemographic groups. Our findings call for strategic implementation of the USPHS's recommendation on treating tobacco use and taking further actions to equip HCPs with the training and resources needed to provide appropriate advice to quit tobacco., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2024 Chandra, Talluri, Fokom Domgue and Shete.)

Background: Secondhand smoke exposure (SHSe) among youth is a serious public health concern, leading to an increased risk of conditions such as asthma and respiratory infections. However, there is little research on SHSe among vulnerable populations, such as racial and sexual minorities. Understanding the factors associated with youth SHSe in homes and vehicles is crucial to developing better protective policies., Methods: This study utilized 2020 data from the National Youth Tobacco Survey, a representative sample of middle- and high-school students in the US. The primary outcomes were youth SHSe at home and while riding in a vehicle. Multinomial regression models were used to assess factors associated with SHSe., Results: The data included 9,912 students enrolled in grades 6 through 12 in the United States who reported never using any form of tobacco. Non-Hispanic Black students living with someone who does not use any form of tobacco products were significantly more likely to experience moderate [OR = 2.1 (1.1-3.9), p  = 0.03] and severe [OR = 5.1 (2.2-11.7), p  < 0.001] secondhand smoke exposure (SHSe) in homes compared to their non-Hispanic White counterparts. Heterosexual female students had lower odds of reporting moderate SHSe in the home compared to heterosexual males [OR = 0.7 (0.6-0.99), p  = 0.02], whereas bisexual females had two-fold increased odds of severe SHSe in homes [OR = 2.0 (1.2-3.4), p  = 0.01]., Conclusion: Significant efforts are needed to develop targeted interventions to reduce SHSe in homes and vehicles, particularly in these vulnerable populations., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2024 Talluri, Shete, Shastri and Shete.)

Mendelian randomization (MR) is an epidemiological framework using genetic variants as instrumental variables (IVs) to examine the causal effect of exposures on outcomes. Statistical methods based on unidirectional MR (UMR) are widely used to estimate the causal effects of exposures on outcomes in observational studies. To estimate the bidirectional causal effects between two phenotypes, investigators have naively applied UMR methods separately in each direction. However, bidirectional causal effects between two phenotypes create a feedback loop that biases the estimation when UMR methods are naively applied. To overcome this limitation, we proposed two novel approaches to estimate bidirectional causal effects using MR: BiRatio and BiLIML, which are extensions of the standard ratio, and limited information maximum likelihood (LIML) methods, respectively. We compared the performance of the two proposed methods with the naive application of UMR methods through extensive simulations of several scenarios involving varying numbers of strong and weak IVs. Our simulation results showed that when multiple strong IVs are used, the proposed methods provided accurate bidirectional causal effect estimation in terms of median absolute bias and relative median absolute bias. Furthermore, compared to the BiRatio method, the BiLIML method provided a more accurate estimation of causal effects when weak IVs were used. Therefore, based on our simulations, we concluded that the BiLIML should be used for bidirectional causal effect estimation. We applied the proposed methods to investigate the potential bidirectional relationship between obesity and diabetes using the data from the Multi-Ethnic Study of Atherosclerosis cohort. We used body mass index (BMI) and fasting glucose (FG) as measures of obesity and type 2 diabetes, respectively. Our results from the BiLIML method revealed the bidirectional causal relationship between BMI and FG in across all racial populations. Specifically, in the White/Caucasian population, a 1 kg/m2 increase in BMI increased FG by 0.70 mg/dL (95% confidence interval [CI]: 0.3517-1.0489; p = 8.43×10-5), and 1 mg/dL increase in FG increased BMI by 0.10 kg/m2 (95% CI: 0.0441-0.1640; p = 6.79×10-4). Our study provides novel findings and quantifies the effect sizes of the bidirectional causal relationship between BMI and FG. However, further studies are needed to understand the biological and functional mechanisms underlying the bidirectional pathway., Competing Interests: he authors have declared that no competing interests exist., (Copyright: © 2024 Zou et al.

Background: We examined the awareness, interest, and information sources relating to cannabis use for cancer management (including management of cancer symptoms and treatment-related side effects) and determined factors associated with cancer survivors' awareness and interest in learning about cannabis use for cancer management., Methods: This was a cross-sectional study of adult cancer survivors (N = 1886) receiving treatment at a comprehensive cancer center. Weighted prevalence and multivariable logistic regression analyses were conducted., Results: Among cancer survivors, 88% were aware and 60% were interested in learning about cannabis use for cancer management. Common sources of information to learn about cannabis use for cancer management were cancer doctors/nurses (82%), other patients with cancer (27%), websites/blogs (26%), marijuana stores (20%), and family/friends (18%). The odds of being aware of cannabis use for cancer management was lower among male compared to female survivors (adjusted odds ratio [AOR]: 0.61; 95% confidence interval [CI]: 0.41-0.90), non-Hispanic Blacks compared to non-Hispanic Whites (AOR: 0.36; 95% CI: 0.21-0.62), and survivors who do not support the legalization of cannabis for medical use compared to those who do (AOR: 0.10; 95% CI: 0.04-0.23). On the other hand, the odds of being interested in cannabis use for cancer management was higher among non-Hispanic Blacks compared to non-Hispanic Whites (AOR: 1.65; 95% CI: 1.04-2.62), and among cancer survivors actively undergoing cancer treatment compared to patients on non-active treatment (AOR: 2.25; 95% CI: 1.74-2.91)., Conclusion: Awareness of cannabis use for cancer management is high within the cancer survivor population. Results indicated health care providers are leading information source and should receive continued medical education on cannabis-specific guidelines. Similarly, tailored educational interventions are needed to guide survivors on the benefits and risks of cannabis use for cancer management., (© 2024 The Authors.

Background: There is increasing discourse on the use of cannabis as a palliative for cancer/cancer-treatment-related symptoms. We described the prevalent reasons for use, perceived benefits, and awareness of health risks from cannabis use for cancer management among cancer survivors., Methods: Cross-sectional survey of adult (≥ 18 years) cancer survivors from 41 US states receiving treatment at a comprehensive cancer center., Results: Of 1,886 cancer survivors included, 17.4% were current users, 30.5% were former users, and 52.2% were never users of cannabis. Among survivors who currently or formerly used cannabis after their cancer diagnosis (n = 510), the reasons for cannabis use in cancer management were; sleep disturbance (60%), pain (51%), stress (44%), nausea (34%), and mood disorder/depression (32%). Also, about a fifth (91/510) of survivors used cannabis to treat their cancer. Across the different symptoms assessed, over half of the survivors who reported a reason for using cannabis currently or after their cancer diagnosis perceived that cannabis was helpful to a great extent in improving their symptoms. However, of the 167 survivors who reported awareness of potential health risks from cannabis use, the awareness of adverse health risks associated with cannabis use was low: suicidal thoughts (5%), intense nausea and vomiting (6%), depression (11%), anxiety (14%), breathing problems (31%), and interaction with cancer drugs (35%)., Conclusion: Prevalence of cannabis use among survivors was notable, with most reporting a great degree of symptomatic improvement for the specified reason for use. However, only a few were aware of the health risks of cannabis use during cancer management., Implications for Cancer Survivors: With more cancer survivors using cannabis as a palliative in managing their cancer-related symptoms, future guidelines and policies on cannabis use in cancer management should incorporate cannabis-based interventions to minimize the inadvertent harm from cannabis use during cancer treatment among survivors., (© 2023.

Despite growing interest in the use of cannabis for the treatment of cancer-related symptoms, there are limited studies that have assessed the use pattern, type, and mode of delivery of cannabis products used by cancer survivors. This study describes the current state of the use pattern, product type, and mode of delivery of cannabis used by cancer survivors. This was a cross-sectional study of cancer survivors from 41 U.S. states who received treatment at the largest NCI-designated comprehensive cancer center. The weighted prevalence of the use patterns, product types, and modes of delivery of cannabis used by cancer survivors was estimated. A total of 1886 cancer survivors were included in the study, with 915 (48% [95% CI: 45-51]) reporting ever using cannabis. Of survivors who had ever used cannabis, 36% (95% CI: 33-40) were current users. Among survivors who reported cannabis use after diagnosis, 40% used cannabis during and after cancer treatment, 35% used cannabis during treatment, and 25% used cannabis after completing their cancer treatment. Additionally, 48% of survivors reported an increase in cannabis use since cancer diagnosis. The commonest types of cannabis products used by cancer survivors were dry leaf cannabis (71%), cannabidiol (CBD) oil (46%), and cannabis candy (40%). Moreover, cancer survivors frequently used baked goods (32%), creams and gels (21%), and tinctures (18%). Furthermore, among ever users, the predominant mode of use was cannabis inhalation/smoking (69%) compared to eating/drinking (59%). More so, the common mode of inhalation/smoking of cannabis products were rolled cannabis cigarettes (79%), pipes (36%), water pipes (34%), vaporizers or vapes (14%), and e-cigarette devices (14%). A substantial number of cancer survivors use cannabis during cancer treatment, with increased use following cancer diagnosis. The forms and modes of delivery of cannabis varied among survivors, with most survivors inhaling or smoking cannabis. There is a need to educate healthcare providers (HCPs) and survivors on current evidence of cannabis use and strengthen cannabis regulatory frameworks to optimize benefits and minimize adverse events from cannabis use during cancer treatment.

Background: Despite the known benefits of preventing human papillomavirus (HPV)-related cancers, HPV vaccine coverage is low in the United States. Grounded in Social Ecological theory, we assessed the macro-level (state) and meso-level (organization) factors associated with HPV vaccine initiation and up-to-date., Methods: Data from 2020 National Immunization Survey-Teen were used to study a sample of 20 163 US adolescents (aged 13-17 years). The data were collected from each teen's parents or guardians and health-care professionals. Weighted prevalence estimates were calculated, and multivariable regression analyses were conducted., Results: The prevalence of HPV vaccine initiation was 75.1% and of remaining up-to-date was 58.6%. At the macro level, teens living in states with high and moderate religiosity had lower odds of HPV vaccine initiation (high religiosity adjusted odds ratio [AOR] = 0.63, 95% confidence interval [CI] = 0.50 to 0.78; moderate religiosity AOR = 0.68, 95% CI = 0.55 to 0.85) and up-to-date (high religiosity AOR = 0.69, 95% CI = 0.56 to 0.85; moderate religiosity AOR = 0.74, 95% CI = 0.61 to 0.91) than states with low religiosity. At the meso level, when none of their healthcare professionals ordered vaccine from the state, teens had lower odds of initiation (AOR = 0.68, 95% CI = 0.53 to 0.87) and up-to-date (AOR = 0.76, 95% CI = 0.60 to 0.95) than teens whose healthcare professionals ordered vaccine from the state. In addition, race and ethnicity, age, mother's education level, household income, well-child examination status, and doctor's recommendation were significantly associated with HPV vaccine uptake., Conclusion: A multiprong approach is needed to address religious and systemic barriers to HPV vaccination and expand healthcare professionals' access and enrollment in state vaccine initiatives, such as the Vaccine for Children program., (© The Author(s) 2023. Published by Oxford University Press.)

The most important determinant of HPV vaccination uptake is healthcare provider recommendation, yet not all eligible patients receive HPV vaccination recommendations. We used data from the 2020 National Immunization Survey-Teen to determine individual, systemic, and state factors associated with provider recommendation of HPV vaccination. A total of 18,534 teens were included, with 81.4% receiving provider recommendations for HPV vaccination. HPV vaccination recommendation was higher among females compared to males (AOR: 1.57; 95% CI: 1.27-1.93), teens who received a well-child exam at 11 or 12 years compared to those who did not (AOR: 2.10; 95% CI: 1.61-2.74), and teens whose mothers had college, some college or at least a high school education compared to those with less than high school education. In addition to individual factors, provider recommendation of HPV vaccination was higher in hospitals (AOR: 1.51; 95% CI: 1.00-2.29) and STD/school/teen clinics (AOR: 2.47; 95% CI: 1.05-5.78) compared to public facilities. However, the odds of provider recommendation were lower when none of the teen's providers ordered vaccines from the state compared to when all teen providers ordered vaccines from the state (AOR: 0.69; 95% CI: 0.52-0.93). Moreover, the state's mean prevalence of provider recommendations of HPV vaccination was 7.2% lower (Coefficient: -0.072; 95% CI: -0.107 - -0.036) in states with high religious ideology compared to those with low religious ideology. Interventions to increase provider recommendation of HPV vaccination should take a multiprong and comprehensive approach that addresses religious and systemic barriers to HPV vaccination recommendation.

Background: Transplant recipients have a 2- to 4-fold increased risk of developing malignancies over the general population. Cancer is the second most common cause of death for recipients. The magnitude of the risk depends on the cancer type and increases in viral-related malignancies. Skin cancer is the most common. However, data in most cancer registries is limited to cutaneous melanomas, thereby limiting the epidemiologic examination of cancer risk in non-melanoma skin cancer. Our goal was to evaluate post-kidney transplant cancer cases and sites in our population to guide screening recommendations., Methods: Between 2009 and 2015, a retrospective study of adult kidney recipients transplanted at East Carolina University was conducted. The first cancer diagnosis after transplant through February 18, 2020, was captured and analyzed. Patient demographics, cancer sites, and histological diagnoses were analyzed and compared. p16 immunohistochemistry was used as a surrogate marker for high-risk human papillomavirus (HPV) infection., Results: Retrospectively, kidney transplant recipients were analyzed (N = 439), the majority were non-Hispanic Black (NHB) individuals, 312 (71.1%), and 127 (28.9%) were non-Hispanic White (NHW) individuals. Of these, 59 (13.4%) developed a posttransplant malignancy, with the majority on sun-exposed skin found in NHW. NHB had all anogenital/mucosa skin cancers on non-sun-exposed skin. Of these detected in NHB, all were squamous cell carcinomas, with five out of six (83.3%) being positive for p16., Conclusions: Posttransplant malignancy differed significantly by race, site, and potential source of etiology. The majority of malignancies are likely explained by acceleration of precursor lesions from prior exposure to ultraviolet rays or HPV., (© 2022 The Authors.

Background: In 2021, the U.S. Preventive Services Task Force (USPSTF) updated its recommendation to expand lung cancer screening (LCS) eligibility and mitigate disparities. Although this increased the number of non-White individuals who are eligible for LCS, the update's impact on drivers of disparities is less clear. This analysis focuses on racial disparities among Black individuals because members of this group disproportionately share late-stage lung cancer diagnoses, despite typically having a lower intensity smoking history compared to non-Hispanic White individuals., Methods: We used data from the National Health Interview Survey to examine the impact of the 2021 eligibility criteria on racial disparities by factors such as education, poverty, employment history, and insurance status. We also examined preventive care use and reasons for delaying medical care., Results: When comparing Black individuals and non-Hispanic White individuals, our analyses show significant differences in who would be eligible for LCS: Those who do not have a high school diploma (28.7% vs. 17.0%, p = 0.002), are in poverty (26.2% vs. 14.9%, p < 0.001), and have not worked in the past 12 months (66.5% vs. 53.9%, p = 0.009). Further, our analyses also show that more Black individuals delayed medical care due to not having transportation (11.1% vs. 3.6%, p < 0.001) compared to non-Hispanic White individuals., Conclusions: Our results suggest that despite increasing the number of Black individuals who are eligible for LCS, the 2021 USPSTF recommendation highlights ongoing socioeconomic disparities that need to be addressed to ensure equitable access., (© 2022 The Authors.

Introduction: Both the triglyceride to HDL cholesterol (TG/HDL) ratio and timing of pubertal maturation have been identified as independent contributors to the development of atherosclerosis., Objective: The purpose of our study was to determine the relationship between the TG/HDL ratio and measures of vascular health in children and adolescents with dyslipidemia stratified by somatic maturity. We hypothesized that somatic maturity would have a significant interaction with TG/HDL ratio and vascular health., Methods: This was a longitudinal analysis of 120 children and adolescents (age 8-14 years) with dyslipidemia recruited from a pediatric preventive cardiology clinic. At baseline and each follow-up visit, a non-fasting serum lipid panel was collected and vascular health (carotid artery intima--media thickness, pulse wave velocity, augmentation index) was assessed. Peak height velocity (PHV) was calculated at each visit, and participants were stratified into groups by maturity offset (pre-PHV, mid-PHV, post-PHV). A mixed model design permitted baseline and follow-up visits to be classified as discrete data points., Results: Of the n = 235 data points (pre-PHV = 23%, mid-PHV = 19%, and post-PHV = 58%), we identified no significant interaction between TG/HDL ratio, maturity offset, and measures of vascular structure or function. There was also no significant relationship found between TG/HDL and maturity group. Within the mid-pubertal group, there was weak relationship found between TG/HDL and augmentation index., Conclusion: Despite the well-described relationship between early pubertal maturation and development of cardiovascular risk factors in adulthood, we found that vascular damage resulting from an elevated TG/HDL ratio is not independently associated with somatic maturity., (© 2022 Wiley Periodicals LLC.)

Background: Menthol cigarette use is associated with higher smoking initiation and reduced smoking cessation. We investigated sociodemographic differences in menthol and nonmenthol cigarette use in the United States., Methods: We used the most recent available data from the May 2019 wave of the nationally-representative Tobacco Use Supplement to the Current Population Survey. The survey weights were used to estimate the national prevalence of individuals who currently smoke among individuals who use menthol and nonmenthol cigarettes. Survey-weighted logistic regression methods were used to estimate the association of menthol cigarette use with formerly smoking cigarettes and attempting to quit within the past 12 months while adjusting for several sociodemographic factors associated with smoking., Results: The prevalence of current smoking in individuals who ever smoked menthol cigarettes was higher 45.6% (44.5%-46.6%) compared to 35.8% (35.2%-36.4%) in individuals who ever smoked nonmenthol cigarettes. Non-Hispanics Blacks who used menthol cigarettes had a higher likelihood of being an individual who currently smokes (OR 1.8, 95% CI: [1.6-2.0], P -value <.001) compared to Non-Hispanic Whites who used nonmenthol cigarettes. However, Non-Hispanics Blacks who used menthol cigarettes were more likely to make a quit attempt (OR 1.4, 95%CI: [1.3-1.6], P -value <.001) compared to non-Hispanic Whites who used nonmenthol cigarettes., Conclusions: Individuals who currently use menthol cigarettes are more likely to make attempts to quit smoking. However, this did not translate to successfully quitting smoking, as evidenced by the proportion of individuals who formerly smoked within the population which used menthol cigarettes.

Objective: We sought to determine the clinical and histopathological factors associated with intestinal hemorrhage and its correlation with clinical outcomes in neonates with surgical necrotizing enterocolitis (NEC)., Methods: A retrospective study compared clinical and histopathology information in neonates following surgical NEC with severe hemorrhage and those with mild/moderate hemorrhagic lesions seen on resected intestine pathology., Results: The infants with severe hemorrhage (Grade 3-4, 81/148, 54.7%) had significantly lower exposure to antenatal steroids (52.5 % vs 76.9 %; p = 0.004), had higher gestational age (28.5 weeks [7.14] vs. 26.58 [2.90]; p = 0.034), lost more bowel length (p = 0.045), had higher CRP levels at 2 weeks (p = 0.035), and had less intestinal failure ([30.3 % vs 52.5 %]; p = 0.014) than mild/moderate (Grade 0-2, 67/148, 45.2%) hemorrhage group. Those with severe hemorrhage had significantly higher mean inflammation score (2.67 [0.94] vs. 1.63 [0.92]; p = <0.001), higher necrosis scores (1.95 [1.28] vs. 1.49 [1.35]; p = 0.037), higher neovascularization (p = 0.01), higher fibroblasts (p = 0.023) and higher lymphocyte percentages up to 48 hours (p < 0.05) following NEC than mild/ moderate hemorrhage group.On multivariable regression, less exposure to antenatal steroids (OR 0.18 [95% CI 0.05-0.58]; p = 0.005), higher inflammation (OR 3.7 [95% CI 2.09-7.32]; p = 0.001), and lymphocyte count on the day of onset/24 hours following NEC (OR 1.06 [95% CI 1.02-1.11]; p = 0.005) were independently associated with a higher odd of severe intestinal hemorrhage., Conclusion: The surgical NEC infants with intestinal hemorrhage were less likely to have antenatal steroid exposure but had higher inflammation grade and lymphocyte counts following NEC onset on multivariable regression modeling.

Amid subpar uptake of HPV vaccination in the United States, gender-generated disparities in HPV vaccination uptake have the potential to perpetuate existing disparities in HPV-associated cancers. Yet few studies have investigated the influence of parent-child gender on intentions to refuse HPV vaccination due to safety concerns/side effects. This study used nationally representative data, spanning 2010-2019, from the National Immunization Survey-Teen (NIS-Teen). NIS-Teen respondents are parents/guardians or primary caregivers of adolescents 13-17 years old living in the United States. Over the study period, intentions to refuse HPV vaccination due to safety concerns rose among all parent-child gender pairings but were highest among respondent mothers regarding their unvaccinated daughters. The results revealed a statistically significant increased likelihood of having intentions to refuse HPV vaccination due to safety concerns among all parent-child combinations compared with father-son pairs. These odds were consistently highest among mother-daughter pairs. In 2019, compared with father-son pairs, fathers were 1.94 (95% CI: 1.21-3.12) times more likely to report the intention to not vaccinate against HPV for their daughters, while mothers were 2.23 (95% CI: 1.57-3.17) and 2.87 (95% CI: 2.02-4.09) times more likely to report intentions to refuse HPV vaccination for their sons and daughters, respectively. These findings were persistent and constantly increased over the 10-year study period. Interventions aimed at correcting gender-based misperceptions and countering misinformation about the safety of the HPV vaccine are warranted.
