Prevalence of Lower Urinary Tract Symptoms in Women Planning to Undergo Hysterectomy for Uterine Leiomyoma and Abnormal Uterine Bleeding.

Introduction: Leiomyomas are associated with lower urinary tract symptoms (LUTS), but more specific characterization of their impact on LUTS is needed. Methods: This is a retrospective cohort study of 202 participants (101 per group) who underwent hysterectomy for leiomyomas versus abnormal uterine bleeding nonclassified (AUB-N) from July 2015 to May 2019. Baseline demographics, leiomyoma characteristics, and presence of baseline LUTS were collected. The main objective was to compare the prevalence of LUTS between these two groups. Secondary objectives were to analyze the association between leiomyoma characteristics and the prevalence of LUTS. Results: There was no difference in baseline prevalence of LUTS between the hysterectomy for leiomyoma versus AUB-N groups (42.6% vs. 45.5%, p = 0.67). When examining the entire study cohort of participants, irrespective of hysterectomy indication, leiomyoma size >6 cm was associated with an increased prevalence of LUTS when compared with leiomyoma <6 cm (64.9% vs. 40.4%, p = 0.02), and specifically difficulty passing urine (p = 0.02), nocturia (p = 0.04), and urinary frequency (p = 0.04). When controlling for age, body mass index, parity, chronic pelvic pain, and diabetes, leiomyomas >6 cm remained significantly associated with the presence of LUTS (odds ratio 3.1, 95% confidence interval = 1.2-8.3) when compared with leiomyoma <6 cm. Presence of >1 leiomyoma was associated with urinary frequency (67.9% vs. 32.1%, p = 0.02) when compared with ≤1 leiomyoma. Anterior location and uterine volume were not associated with a difference in LUTS. Conclusion: LUTS are prevalent in those planning hysterectomy for leiomyoma and AUB-N. Leiomyomas >6 cm are associated with the presence of LUTS. Future studies should evaluate change in LUTS following hysterectomy for leiomyomas.

Fertility preservation choices and decisional regret after gender-affirming surgery in transgender men or gender nonbinary persons.

Objective: To investigate the prevalence of decisional regret regarding preoperative fertility preservation choices after gender-affirming surgery or removal of reproductive organs. Design: Cross-sectional. Setting: University-based pratice. Patients: A total of 57 survey respondents identifying as transgender men or gender nonbinary with a history of gender-affirming surgery or removal of reproductive organs between 2014 and 2023 with the University of North Carolina Minimally Invasive Gynecology division. Intervention: Survey or questionnaire. Main Outcome Measures: The prevalence and severity of decisional regret regarding preoperative fertility preservation choices were measured with the use of the validated decisional regret scale (DRS) (scored 0-100). Secondary outcomes included patient-reported barriers to pursuing reproductive endocrinology and infertility consultation and fertility preservation treatment. Results: The survey response rate was 50.9% (57/112). "Mild" to "severe" decisional regret was reported by 38.6% (n = 22) of survey respondents, with DRS scores among all respondents ranging from 0-85. Higher median DRS scores were associated with patient-reported inadequacy of preoperative fertility counseling regarding implications of surgery on future fertility or family-building (0 vs. 50) and fertility preservation options (0 vs. 12.5). No desire for future fertility at the time of fertility counseling was the most frequent reason (68.4%) for declining a referral to reproductive endocrinology and infertility for additional fertility preservation discussion. Conclusions: Decisional regret regarding preoperative fertility preservation choices is experienced among transgender men or gender nonbinary persons after gender-affirming surgery or the removal of reproductive organs. Preoperative, patient-centered fertility counseling and fertility preservation treatments should be provided to reduce the risk of future regret.

The impact of COVID-19 on adolescent wellness in Chicago.

PURPOSE: This study aimed to understand the impact of the initial COVID-19 pandemic remote schooling period on self-reported wellness among adolescents in Chicago. METHODS: Students (n = 55) completed a 22-item wellness questionnaire before (February 2020) and shortly after the onset of the COVID-19 outbreak (April 2020). Precomparisons/postcomparisons (overall and by survey item) were evaluated using two-sided paired t-tests with an alpha level of 0.05. Descriptive statistics were used to evaluate mean scores overall by demographic variables. RESULTS: Significant differences were found in the following areas: Balance (Pre: 7.3, During: 6.4, p = 0.02), Education (Pre: 8.4, During 7.7, p = 0.03) and Friends (Pre:8.0, During: 6.3, p = 0.001). Overall wellness scores varied by demographic variables, though not significantly. CONCLUSIONS: Results suggest the onset of the pandemic impacted students' ability to effectively learn, as well as to maintain balance in their lives and social relationships. Comprehensive support is needed in these areas to promote adolescent wellness.

Food Insecurity in the Food Allergic Population: A Work Group Report of the AAAAI Adverse Reactions to Foods Committee.

Food allergies affect 32 million Americans. Restricted diets due to food allergies can be difficult to maintain especially when the household is food insecure. Food insecurity is defined as the inability to acquire food for household members due to insufficient money or resources for food. The COVID-19 pandemic has caused many people to face food insecurity for the first time with Latinx, Native American, and Black communities disproportionately affected. Because of the increase in food insecurity, this work group developed a survey regarding food insecurity screening. This survey was sent out to a random sample of American Academy of Allergy Asthma & Immunology members to assess food insecurity knowledge and practices. The majority of survey participants did not routinely screen their patients for food insecurity. The biggest barrier identified to screening was lack of knowledge of how to perform a screen and resources available when a patient screened positive. This work group report provides guidance on how to implement and perform a food insecurity screen, including federal resources and assistance programs.

Oral Immunotherapy-Related Awareness, Attitudes, and Experiences Among a Nationally Representative Sample of Food Allergy Patients/Caregivers.

BACKGROUND: Advances in oral immunotherapy (OIT) have led to recently expanded treatment options for food allergy (FA) patients. However, to inform future outreach efforts and ensure equitable access to emerging treatments, a greater understanding of current OIT-related awareness, attitudes, and experiences is needed. OBJECTIVE: To characterize current OIT awareness, attitudes, and experiences among a nationally representative sample of U.S. adults with FA and parents/caregivers of pediatric patients. METHODS: A probability-based sample of U.S. adults and parents/caregivers of children with FA was surveyed about OIT-related knowledge, attitudes, and experiences. RESULTS: Surveys were completed by respondents (n = 781) from all 50 states. Overall, 72% did not know what OIT was prior to the survey. Respondents from households earning over $100,000 or with a college degree each had significantly greater odds of reporting any OIT awareness compared with lower-income (odds ratio 2.0; 95% confidence interval 1.2-3.4) and non-college-educated (odds ratio 1.9; 95% confidence interval 1.2-3.0) respondents. Among respondents familiar or unfamiliar with OIT, 54% and 34%, respectively, reported their expected treatment outcome was to obtain protection against accidental exposure. Among respondents familiar or unfamiliar with OIT, 38% and 35%, respectively, reported their expected treatment outcome to be curing the allergy. Furthermore, 55% of OIT unfamiliar respondents said they would not be comfortable initiating a conversation with their health care provider about their suitability for OIT. CONCLUSIONS: This study shows that, among a nationally representative sample of FA patients and pediatric caregivers, awareness of OIT is low, and over 95% of patients lack personal experience with OIT. Furthermore, the data suggest current OIT awareness is disproportionately elevated among wealthier, more highly educated respondents.

Characterizing Biphasic Food-Related Allergic Reactions Through a US Food Allergy Patient Registry.

BACKGROUND: Understanding about patient-reported biphasic food-related allergic reactions is currently sparse. OBJECTIVE: To characterize patient-reported biphasic food-related allergic reactions among a national food allergy registry. METHODS: We used two patient registry surveys established by Food Allergy Research and Education. Variables were described with proportions and 95% confidence intervals (CIs); unadjusted results were stratified by respondent type. Multivariable logistic regression evaluated the adjusted odds of reporting a biphasic reaction. RESULTS: The incidence of reported biphasic reactions was 16.4% (95% CI, 15.3-17.7). A total of 12.8% of parent or guardian respondents (95% CI, 12.5-14.3) and 21.8% of self-respondents (95% CI, 19.7-23.8) indicated a biphasic reaction during their most recent food-allergic reaction. Among respondents with a mild initial reaction, 7.4% reported a biphasic reaction, compared with 30% with a very severe initial reaction. When the initial reaction was mild, 69.6% of parent or guardian respondents (95% CI, 47.2-85.4) and 52.0% of self-respondents (95% CI, 38.0-35.7) with a biphasic reaction reported a mild secondary reaction. When the initial reaction was very severe, 36.3% of parent or guardian respondents (95% CI, 26.4-47.5) and 42.9% of self-respondents (95% CI, 31.1-55.5) with a biphasic reaction reported a very severe secondary reaction. Female sex, Black race, reaction age 5-12 and 26-66 years, initial moderate, severe, or very severe reaction, and one or more annual reactions were associated with increased odds of a biphasic reaction. CONCLUSIONS: This study characterizes the incidence of patient-reported biphasic reactions and provides valuable information on the probable severity of a biphasic food-related allergic reaction. Further research is necessary to understand the epidemiology of food-related biphasic reactions.

Addressing the social needs of individuals with food allergy and celiac disease during COVID-19: A new practice model for sustained social care.

COVID-19 has led to high rates of food insecurity. Food insecure patients with food allergy and celiac disease are especially vulnerable during the pandemic when foods become limited. This paper describes a practice innovation implemented by a community-based organization, Food Equality Initiative (FEI), whose mission is improving health and ending hunger among individuals with food allergy and celiac disease. FEI responded to the pandemic by converting their in-person pantries to a contactless delivery of safe foods. The practice innovation is discussed in relation to three system-level elements necessary to sustain the integration of social care into the delivery of healthcare.

Egg Allergy in US Children.

BACKGROUND: Egg allergy is common in young children (<5 years) and has significant negative impacts on quality of life. OBJECTIVE: The objective of this study was to characterize egg allergy prevalence, severity, baked egg tolerance, and other associated factors in a large US cohort. METHODS: A national cross-sectional survey was administered from October 2015 to September 2016, resulting in complete parent-proxy responses for 38,408 children. Weighted proportions were estimated to compare egg allergy prevalence and characteristics between key subpopulations. RESULTS: The overall prevalence of current, convincingly egg allergy was 0.9% among all children and 1.3% among children <5 years. Black children were over-represented among children with egg allergy, accounting for 23.4% (95% confidence interval: 13.1-38.4) of egg-allergic children despite comprising 13.2% (12.3-14.2) of the US pediatric population. Among children with egg allergy, 64.2% reported baked egg tolerance and 60.2% had allergy to other foods, with 29.3% having peanut allergy. Asthma was more prevalent in children with an egg allergy than children with other top 8 food allergies (46.5% [35.8-57.4] vs 33.2% [29.6-37.0], P < .05). Among children with current egg allergy, those with baked egg tolerance reported that their food allergy resulted in significantly reduced psychosocial burden, relative to their baked egg-allergic counterparts (M = 3.1 [2.9-3.3] vs M = 3.7 [3.5-3.9]). CONCLUSIONS: Egg allergy is common amongst young children. Nearly two-thirds of children with egg allergy reported baked egg tolerance. Increased efforts are needed to ensure that children with egg allergy are appropriately evaluated as many have comorbid allergic disease and determination of baked egg tolerance may improve quality of life.

Limits in accuracy and a strategy of RNA structure prediction using experimental information.

RNA structural complexity and flexibility present a challenge for computational modeling efforts. Experimental information and bioinformatics data can be used as restraints to improve the accuracy of RNA tertiary structure prediction. Regarding utilization of restraints, the fundamental questions are: (i) What is the limit in prediction accuracy that one can achieve with arbitrary number of restraints? (ii) Is there a strategy for selection of the minimal number of restraints that would result in the best structural model? We address the first question by testing the limits in prediction accuracy using native contacts as restraints. To address the second question, we develop an algorithm based on the distance variation allowed by secondary structure (DVASS), which ranks restraints according to their importance to RNA tertiary structure prediction. We find that due to kinetic traps, the greatest improvement in the structure prediction accuracy is achieved when we utilize only 40-60% of the total number of native contacts as restraints. When the restraints are sorted by DVASS algorithm, using only the first 20% ranked restraints can greatly improve the prediction accuracy. Our findings suggest that only a limited number of strategically selected distance restraints can significantly assist in RNA structure modeling.
