Overall, initiation and adherence to ET are suboptimal, though reasons are not well described. The study’s objective was to better understand ET decision making, prescribing, and patient management from oncology providers’ perspectives.Methods: Using purposive sampling, we recruited oncology providers who saw five or more breast cancer patients per week (n=20). We conducted 30–45-minute telephone interviews, using a semistructured guide to elicit perspectives on ET use. We used thematic content analysis to systematically identify categories of meaning and double-coded transcripts using Atlas.ti.Results: Providers recommend ET to all eligible patients except those with contraindications or other risk factors. Providers base their ET prescribing decisions on the patient’s menopausal status, side effects, and comorbidities. ET is typically discussed multiple times: at the onset of breast cancer treatment and in more detail after other treatment completion. Providers felt that the associated recurrence risk reduction is the most compelling argument for patients during ET decision making. While providers rarely perceived noninitiation as a problem, nonadherence was prevalent, often due to unresolvable side effects.Conclusion: From the clinicians’ perspectives, side effects from ET are the dominant factor in nonadherence. Efforts to improve adherence should focus on strategies to minimize side effects and ensure clinicians and patients are well informed regarding optimal side effect management. This finding has important implications for novel endocrine regimens that offer improved outcomes through longer duration or more intensive therapy.

We examined child temperamental characteristics and family environment characteristics as predictors of the level of parent-child agreement on household safety rules. Fifty children (ages 4-7) and their parents participated. Linear regression analysis indicated that child temperamental characteristics and family characteristics predicted parent-child rule agreement. Child activity level and family orientation toward social and recreational activities were significant predictors. The findings of this study highlight the importance of not relying only on household rules as a method of keeping children safe. [ABSTRACT FROM AUTHOR]

We sought to determine the types of commercials and the actual nutritional content of foods advertised to children during Saturday morning and to adults in evening prime time on 4 television broadcast networks. Food commercials for morning programming were greater in number and repetitions and took up more time overall. Foods advertised in the commercials were coded for actual nutritional content. In general, the morning commercials advertised more unhealthy food products than the evening commercials. Specifically, the morning food commercials advertised unhealthy products in terms of sugar and cholesterol. Viewers of both time periods were subjected to advertisements for unhealthy foods. These types of influences on children's health and development have a potentially negative impact and should be empirically investigated by child health care professionals. [ABSTRACT FROM AUTHOR]

Bacteroides spp. conjugative transposon Tn5030 is 150 kb which includes a 43 kb characterized region containing a number of defined genes and an open reading frame (ORF). The 43 kb region is organized with the ORF1 immediately upstream from the ermF gene, coding for an RRNA methylase, then an unknown 20 kb region downstream followed by the tetQ gene (coding for a ribosomal protection protein) then the rteA and rteB genes. The role of ORF1 is unclear; rteA is a putative sensor and rteB a regulator. Thirty-seven (62%) of 60 isolates, representing one Gram-positive anaerobic and 13 Gram-negative anaerobic species, co-transferred the ermF and tetQ genes to an unrelated Enterococcus faecalis recipient. We used the polymerase chain reaction to show the linkage between ORF1, ermF, tetQ, rteA and rteB. Our data suggest that the ORF1 gene product may participate in the transfer of the ermF gene with or without the ORF1-rteB region and has homology to bacterial transposases. Isolates that co-transferred the ermF and tetQ genes carried and transferred the rteB gene, suggesting that the rteB gene product may be important in transfer of the 43 kb ORF1-rteB region to E. faecalis. The rteB gene product is not required when ermF is transferred independently of tetQ. [ABSTRACT FROM PUBLISHER]

The mefE gene codes for a membrane bound efflux protein, which confers resistance to macrolides, and has been identified in Streptococcus pneumoniae. A variety of Gram-positive organisms were examined. Twenty-six isolates of S. pneumoniae carried mefE and were resistant to erythromycin (MIC of 2-16 mg/L). Two additional isolates of Emr S. pneumoniae carried both ermB and mefE (MIC of 16-128 mg/L). One Micrococcus luteus, one Corynebacterium jeikeium, three Corynebacterium spp., two viridans streptococci and seven Enterococcus spp. also carried mef genes. It was possible to move the mef gene from all 11 S. pneumoniae tested to susceptible S. pneumoniae and/or Enterococcus faecalis recipients. The addition of DNase (1 g/L) did not affect the gene transfer. It was also possible to move the mef gene from donor Enterococcus spp., viridans streptococci, M. luteus, C. jeikeium and Corynebacterium spp. to E. faecalis recipients. Transconjugant isolates were resistant to erythromycin (MIC = 16 mg/L). Hybridization with a labelled mef oligonucleotide probe against Southern blots and bacterial dot blots confirmed the presence of the mef genes. This is the first time that a mobile mef gene has been identified in four different genera, from three distinct geographical locations. [ABSTRACT FROM PUBLISHER]

We screened 183 different clinical anaerobic and aerobic bacteria isolated from humans and other animals for the presence of the ermF gene using a polymerase chain reaction (PCR) assay. The ermF gene was detected in 107 (58%) clinical isolates, including 42 (61%) of 69 Gram-positive bacteria and 65 (57%) of 114 Gram-negative bacteria. Twenty-five ATCC isolates were also tested; 20 (80%) carried the ermF gene. The gene products from the ermFPCR from four isolates were sequenced and showed 95-99% nucleotide homology with the ermF gene and 98-99% amino acid homology with the gene product. Eleven (58%) of the 19 Gram-negative donors tested were able to transfer the ermF gene. All nine (100%) of the Gram-positive donors tested transferred the ermF gene, using either Enterococcus faecalis or Haemophilus influenzae as the recipients. [ABSTRACT FROM PUBLISHER]

Seventy tetracycline-resistant Streptococcus pneumoniae were tested for the presence of tetracycline resistance genes, tetM and tetO, using a polymerase chain reaction (PCR) assay and DNA-DNA hybridization. Seven isolates representing five serotypes (12, 22, 6A, 19F and 23) carried the tetO gene. Five of the isolates were genetically unrelated as judged using pulsed field gel electrophoresis (PFGE) analysis. Two 19F isolates came from the same patient, carried both tetM and tetO genes and had the same PFGE pattern. The other 63 isolates carried only the tetM gene. DNA sequences from three of the tetO-carrying isolates were determined; they showed 91-95% nucleotide sequence identity over 300 nucleotides, and 93-95% amino acid sequence identity over 100 amino acids. The isolates carrying both tetO and tetM genes could transfer the tetM gene into both Enterococcus faecalis and S. pneumoniae recipients, but not the tetO gene. There was no detectable transfer of the tetO gene, by conjugation, from the other five isolates. [ABSTRACT FROM PUBLISHER]

Purpose: Streptococcus mutans is the primary organism associated with dental caries, an infectious, bacterial, and multi-factorial disease that remains the world's most common biofilm-related dental disease. However, the relationship between caries experience and the salivary mutans streptococci (MS) load is controversial. By understanding this relationship, we might better link caries activity to microbial diagnostic tests and improve caries management. This study aims to determine if caries experience in children is associated with salivary bacterial load of MS.Methods and Materials: We acquired adult institutional review board consent from parents and consent from their children to conduct oral examinations and collect buccal and salivary samples. A total of 149 children (88 female, 61 male; 11-15 years) were recruited. Overall, the children were healthy, with 91.8% having no history of major disease. Most children had permanent dentition (80.4%). The children presented with no decay (35%), low decay (32%, <3 D+F), and high decay (33%, =3 D+/-F) surfaces. From the 149 children, 20 with high caries experience and 20 with no caries were selected for study of salivary MS levels. The estimation of bacterial load in saliva was determined by radio-labeled ribosomal RNA probes using 10-fold dilutions of saliva samples. The lowest dilution at which salivary MS was detected was scored for correlation with caries experience. These data will be analyzed using the student's t test once all samples are assayed.Results: To date, 29 samples have been assayed, 16 from the high-caries group and 13 from the no-caries group. The high-caries children showed detectable salivary MS at dilutions of 102 and 103, while the no-caries group showed a wide distribution of detection ranging from 102 to 106. Thus, the high-caries group had lower levels of salivary MS than the group with no caries. One possible explanation for this surprising result is that MS in high-caries children may have greater adherence to teeth and, therefore, have low concentrations in saliva.Conclusion: These results emphasize the multi-factorial nature of the dental caries process in which bacteria, diet, oral hygiene, and genetic factors all contribute to the overall risk for caries.

Objective: Observational studies demonstrate reduced mortality after endovascular (EVAR) compared with open aneurysm repair (OAR) for ruptured abdominal aortic aneurysms (rAAAs). We sought to determine national trends in repair type and in-hospital mortality rates for rAAAs., Methods: We analyzed patients with rAAAs managed with OAR or EVAR from 2002 to 2020 in the National Inpatient Sample and evaluated annual trends in volume and in-hospital mortality by repair type. Multilevel mixed effects logistic regression model was fit for patient and system-level risk adjustment. We assessed interactions between time, sex, and Elixhauser index with repair type., Results: We examined 13,376 patients with rAAAs. Of these, 8357 (62.5%) underwent OAR. Patients receiving EVAR were slightly older (73.7 vs 72.5 years; P < .001) with slightly higher mean Elixhauser index (4.0 vs 3.8; P < .001). Unadjusted in-hospital mortality was 37.4% vs 22.4% for OAR and EVAR, respectively. EVAR offered a risk-adjusted survival advantage (odds ratio [OR], 0.39; 95% confidence interval [CI], 0.32-0.46). There was a statistically significant reduction of in-hospital mortality over time in the EVAR group (interaction OR, 0.96; 95% CI, 0.95-0.98). The interaction between Elixhauser index and repair was not statistically significant (interaction OR, 0.95; 95% CI, 0.87-1.05)., Conclusions: Survival rates for OAR and EVAR improved over time. EVAR persistently provided a substantial survival advantage over OAR in patients with rAAAs over the past 2 decades., Competing Interests: Disclosures None., (Copyright © 2024 Society for Vascular Surgery.

Objectives: We sought to understand why some women with early-stage breast cancer decide to forgo or discontinue endocrine therapy (ET), and to identify factors that might lead to greater acceptance of, and long-term adherence to, this treatment., Methods: We conducted in-depth interviews with N = 53 stage I-III HR+ women who were either non-initiators of ET, initiators who discontinued or initiators who continued with variable daily patterns of adherence. An inductive content analysis was performed to explore the decision-making process of women prescribed ET., Results: Qualitative analyses revealed 55 themes that drove complex decision making. The initiators generally trusted their physicians and did little research before starting the medication. Non-initiators were more suspicious of the medical system, believing that ET presented more risks than benefits. Most discontinuers stopped ET because of side effects. Both non-initiators and discontinuers indicated that push-back from their physicians could have changed their decision. Stories and social support were important in decision making., Conclusions: Although ET can significantly reduce the risk of breast cancer recurrence, substantial barriers prevent many women from initiating or continuing it., Practice Implications: Physicians have powerful influence over patients' decisions to initiate ET and can be important levers for motivating patients to persist., Competing Interests: Declaration of Competing Interest The authors report no conflicts of interest., (Copyright © 2024 Elsevier B.V.

Background: Previous studies report that patients of racial/ethnic minorities more frequently present with ruptured abdominal aortic aneurysms (rAAAs) than their counterparts. The distribution of rAAA treatment modality, whether open aneurysm repair (OAR) or endovascular aneurysm repair (EVAR), by race/ethnicity classification remains uncertain. This study aims to investigate disparities, as represented by race/ethnic classification, median income, and insurance status, in the management of rAAA in a national cohort., Methods: We conducted a retrospective analysis of patients admitted with rAAA managed with either OAR or EVAR from 2002 to 2020 using the National Inpatient Sample, comparing repair type by race/ethnicity group. Multilevel mixed effects logistic regression models, adjusted for patient- and system-level factors, were used to calculate difference in use of OAR or EVAR dependent on race/ethnicity classification., Results: We identified 10,788 admissions for rAAA repairs, of which 9506 (88.1%) were White, 605 (5.6%) were Black, 424 (3.9%) were Hispanic, and 253 (2.4%) were Asian/Native American. Asians/Native Americans underwent the highest frequency of OAR as compared with EVAR (61.7% vs 38.3%). In the adjusted model, there was no statistically significant difference in the use of OAR vs EVAR by race/ethnicity classification. In total, primary payer and median income were also not statistically significant predictors of AAA treatment modality., Conclusions: Our study found no statistical evidence of disparities with respect to race, insurance, or median income and use of OAR or EVAR for the management of rAAA., Competing Interests: Disclosures None., (Published by Elsevier Inc.)

Background: As a nexus of routine antibiotic use and zoonotic pathogen presence, the livestock farming environment is a potential hotspot for the emergence of zoonotic diseases and antibiotic resistant bacteria. Livestock can further facilitate disease transmission by serving as intermediary hosts for pathogens before a spillover event. In light of this, we aimed to characterize the microbiomes and resistomes of dairy workers, whose exposure to the livestock farming environment places them at risk for facilitating community transmission of antibiotic resistant genes and emerging zoonotic diseases., Results: Using shotgun sequencing, we investigated differences in the taxonomy, diversity and gene presence of 10 dairy farm workers and 6 community controls' gut metagenomes, contextualizing these samples with additional publicly available gut metagenomes. We found no significant differences in the prevalence of resistance genes, virulence factors, or taxonomic composition between the two groups. The lack of statistical significance may be attributed, in part, to the limited sample size of our study or the potential similarities in exposures between the dairy workers and community controls. We did, however, observe patterns warranting further investigation including greater abundance of tetracycline resistance genes and prevalence of cephamycin resistance genes as well as lower average gene diversity (even after accounting for differential sequencing depth) in dairy workers' metagenomes. We also found evidence of commensal organism association with tetracycline resistance genes in both groups (including Faecalibacterium prausnitzii, Ligilactobacillus animalis, and Simiaoa sunii)., Conclusions: This study highlights the utility of shotgun metagenomics in examining the microbiomes and resistomes of livestock workers, focusing on a cohort of dairy workers in the United States. While our study revealed no statistically significant differences between groups in taxonomy, diversity and gene presence, we observed patterns in antibiotic resistance gene abundance and prevalence that align with findings from previous studies of livestock workers in China and Europe. Our results lay the groundwork for future research involving larger cohorts of dairy and non-dairy workers to better understand the impact of occupational exposure to livestock farming on the microbiomes and resistomes of workers., (© 2024.

Precision public health (PPH) considers the interplay between genetics, lifestyle and the environment to improve disease prevention, diagnosis and treatment on a population level-thereby delivering the right interventions to the right populations at the right time. In this Review, we explore the concept of PPH as the next generation of public health. We discuss the historical context of using individual-level data in public health interventions and examine recent advancements in how data from human and pathogen genomics and social, behavioral and environmental research, as well as artificial intelligence, have transformed public health. Real-world examples of PPH are discussed, emphasizing how these approaches are becoming a mainstay in public health, as well as outstanding challenges in their development, implementation and sustainability. Data sciences, ethical, legal and social implications research, capacity building, equity research and implementation science will have a crucial role in realizing the potential for 'precision' to enhance traditional public health approaches., (© 2024.

Background and Aims: Familial hypercholesterolemia is an underdiagnosed genetic metabolic condition limiting the clearance of low-density lipoprotein cholesterol and increasing lifetime risk of cardiovascular disease. Population genetic screening in unselected individuals could quickly identify cases of familial hypercholesterolemia and enable early prevention, but the economic impact of widespread screening on patients has not been studied., Methods: We assessed the cost-effectiveness of population genetic screening for familial hypercholesterolemia in 20 and 35-year-old adults in the United States from the perspective of patients. We developed a decision tree Markov hybrid model to examine diagnoses, cardiovascular disease, cardiac events, quality of life, and costs under population genetic screening compared to family-based cascade testing., Results: While population genetic screening increased diagnoses and reduced incidence of cardiovascular disease, population genetic screening was not cost-effective compared to cascade testing at current levels of willingness to pay. Lower genetic testing costs, combined screening with other genetic conditions, and support to maintain lipid-lowering therapy use over time could improve the cost-effectiveness of population genetic screening., Conclusions: Future research is needed to examine how cost-sharing strategies may affect the cost-effectiveness of screening to patients and how families and providers experience the clinical and economic outcomes of population screening., Competing Interests: Declaration of competing interest LEH received predoctoral fellowship funding from Bristol Myers Squibb.

Nocturia has been increasingly recognized as a manifestation of various non-urological conditions including hypertension. In adults, blood pressure (BP) elevation has been identified as a robust correlate of nocturia, but such a relationship has not been studied in pediatric populations where nocturia is often attributed to hormonal, sleep, physiological or psychological disorders. Accordingly, this study aimed to determine the relationship between nocturia and BP elevation in adolescents. We prospectively studied 100 patients, aged 10-18 years, recruited from pediatric clinics at our institution. Nocturia (defined as ≥ 1 voids on voiding diary analysis) was present in 45% of the study sample (range: 1-4 voids/night). 37% of subjects self-reported awakening to urinate, and 34% of subjects had BP elevation according to age-dependent thresholds from current Pediatrics guidelines. On multivariate analyses, BP elevation was strongly associated with nocturia determined by both voiding diary (OR 26.2, 95% CI: 6.5, 106.0) and self-report. Conversely, nocturia was associated with increased odds of elevated BP by diary (26.3, 95% CI: 6.5, 106.4) and self-report (OR 8.1, 95% CI: 3.2, 20.5). In conclusion, nocturia appears to be common and is strongly associated with BP elevation in adolescents. These findings suggest that eliciting a history of nocturia holds promise as a simple method of identifying adolescents at risk for hypertension., (© 2023.
