ABSTRACT

We investigate the effects of solvents on the geometry, absorption spectrum, and first hyperpolarizability of six push-pull molecules, each containing a 4,5-dicyanoimidazole group as an electron acceptor and a N,N-dimethylamino group as an electron donor, with systematically extended π-conjugated systems. Geometry optimizations in dichloromethane, methanol, water, and formamide under normal thermodynamic conditions were performed using the average solvent electrostatic configuration-free energy gradient method, which employs a discrete solvent model. The conformational structure of molecules is moderately affected by the environment, with the π-conjugated system becoming more planar in protic solvents. Solvent effects on the first hyperpolarizability result in marked increases that are in line with the red shifts of the absorption spectrum. The hyperpolarizability of smaller molecules within the set may be significantly influenced by the effects of geometry relaxation in highly polar protic solvents. The results illustrate the role of hydrogen bonds in the structure and electronic properties of push-pull molecules in protic environments. For smaller molecules, hydrogen bonds significantly contribute to enhancing the hyperpolarizability, but the effect of these specific interactions becomes less significant with the length of the π-conjugated system.

ABSTRACT

OBJECTIVES: Racial disparities are pervasive in access to pediatric surgery. The goal of this study was to test the hypotheses that, compared with White children, non-White and Hispanic children: (1) were less likely to attend evaluations by otolaryngologists after a diagnosis of otitis media (OM) eligible for surgical referral, and (2) these children were less likely to receive tympanostomy tube (TT) after surgical consultation. METHODS: The OptumLabs Data Warehouse is a de-identified claims database of privately insured enrollees. Guidelines on the management of OMs suggest that children should be evaluated for surgery if they have recurrent acute OM or chronic OM with effusion. A cohort of children who were diagnosed with OM were constructed. For Hypothesis 1, the primary outcome was otolaryngology office visit within 6 months of a diagnosis of recurrent or chronic OM. For Hypothesis 2, the outcome was TT placement within 6 months following the otolaryngology office visit. Cox regression models were used to determine the relationship between race/ethnicity and the primary outcomes. RESULTS: Among 187,776 children with OMs, 72,774 (38.8%) had otolaryngology visits. In a multivariate Cox model, the hazard ratios of attending otolaryngology visit for Black, Hispanic, and Asian children were 0.93 (95% CI,0.90, 0.96), 0.86 (0.83, 0.88), and 0.74 (0.71, 0.77), compared with White children. Among the children evaluated by otolaryngologists, 46,554 (63.97%) received TT. Black, Hispanic, and Asian children with recurrent acute OM had lower likelihood of receiving TT. CONCLUSIONS: Racial disparities in attending otolaryngology office visit contributed to the disparities in receiving TT. QUALITY OF EVIDENCE: Level 3 Laryngoscope, 134:3846-3852, 2024.

ABSTRACT

INTRODUCTION: Endoscopic eradication therapy (EET) is standard of care for T1a esophageal adenocarcinoma (EAC). However, data on outcomes in high-risk T1a EAC are limited. We assessed and compared outcomes after EET of low-risk and high-risk T1a EAC, including intraluminal EAC recurrence, extraesophageal metastases, and overall survival. METHODS: Patients who underwent EET for T1a EAC at 3 referral Barrett's esophagus endotherapy units between 1996 and 2022 were included. Patients with submucosal invasion, positive deep margins, or metastases at initial diagnosis were excluded. High-risk T1a EAC was defined as T1a EAC with poor differentiation and/or lymphovascular invasion, with low-risk disease being defined without these features. All pathology was systematically assessed by expert gastrointestinal pathologists. Baseline and follow-up endoscopy and pathology data were abstracted. Time-to-event analyses were performed to compare outcomes between groups. RESULTS: One hundred eighty-eight patients with T1a EAC were included (high risk, n = 45; low risk, n = 143) with a median age of 70 years, and 84% were men. Groups were comparable for age, sex, Barrett's esophagus length, lesion size, and EET technique. Rates of delayed extraesophageal metastases (11.1% vs 1.4%) were significantly higher in the high-risk group ( P = 0.02). There was no significant difference in the rates of intraluminal EAC recurrence ( P = 0.79) and overall survival ( P = 0.73) between the 2 groups. DISCUSSION: Patients with high-risk T1a EAC undergoing successful EET had a substantially higher rate of extraesophageal metastases compared with those with low-risk T1a EAC on long-term follow-up. These data should be factored into discussions with patients while selecting treatment approaches. Additional prospective data in this area are critical.

ABSTRACT

AIMS: To identify longitudinal trajectories of glycemic control among adults with newly diagnosed diabetes, overall and by diabetes type. METHODS: We analyzed claims data from OptumLabs® Data Warehouse for 119,952 adults newly diagnosed diabetes between 2005 and 2018. We applied a novel Mixed Effects Machine Learning model to identify longitudinal trajectories of hemoglobin A1c (HbA1c) over 3 years of follow-up and used multinomial regression to characterize factors associated with each trajectory. RESULTS: The study population was comprised of 119,952 adults with newly diagnosed diabetes, including 696 (0.58%) with type 1 diabetes. Among patients with type 1 diabetes, 52.6% were diagnosed at very high HbA1c, partially improved, but never achieved control; 32.5% were diagnosed at low HbA1c and deteriorated over time; and 14.9% had stable low HbA1c. Among patients with type 2 diabetes, 67.7% had stable low HbA1c, 14.4% were diagnosed at very high HbA1c, partially improved, but never achieved control; 10.0% were diagnosed at moderately high HbA1c and deteriorated over time; and 4.9% were diagnosed at moderately high HbA1c and improved over time. CONCLUSIONS: Claims data identified distinct longitudinal trajectories of HbA1c after diabetes diagnosis, which can be used to anticipate challenges and individualize care plans to improve glycemic control.

ABSTRACT

AIMS: To characterize glucagon fill rates and costs among youth with type 1 diabetes mellitus (T1DM). METHODS: Claims-based analysis of commercially-insured youth with T1DM included in OptumLabs® Data Warehouse between 2011 and 2021. Glucagon fill rates and costs were calculated overall and by formulation (injectable, intranasal, autoinjector, and pre-filled syringe). Sociodemographic and clinical factors associated with glucagon fills were examined using Cox regression. RESULTS: We identified 13,267 children with T1DM (76.4% non-Hispanic White). Over mean follow-up of 2.81 years (SD 2.62), 70.0% filled glucagon, with stable fill rates from 2011 to 2021. Intranasal glucagon had rapid uptake following initial approval, and it accounted for almost half (46.6%) of all glucagon fills by 2021. Family income was positively associated with glucagon fills in a stepwise fashion (HR 1.39 [95% CI 1.27-1.52] for annual household income ≥$200,000 vs. <$40,000), while Black race was negatively associated with fills (HR 0.83 [95% CI 0.76-0.91]) compared to White race). Annual mean out-of-pocket costs ranged from $21-$68 (IQR $29-$44). CONCLUSION: Roughly 30% of commercially-insured youth with T1DM may lack access to unexpired glucagon, with significant disparities among Black and low-income patients. Health systems, clinicians, schools, and caregivers should work together to ensure children have reliable access to this critical medication.

ABSTRACT

An overwhelming body of evidence points to an inextricable link between race and health disparities in the United States. Although race is best understood as a social construct, its role in health outcomes has historically been attributed to increasingly debunked theories of underlying biological and genetic differences across races. Recently, growing calls for health equity and social justice have raised awareness of the impact of implicit bias and structural racism on social determinants of health, healthcare quality, and ultimately, health outcomes. This more nuanced recognition of the role of race in health disparities has, in turn, facilitated introspective racial disparities research, root cause analyses, and changes in practice within the medical community. Examining the complex interplay between race, social determinants of health, and health outcomes allows systems of health to create mechanisms for checks and balances that mitigate unfair and avoidable health inequalities. As one of the specialties most intertwined with social medicine, emergency medicine (EM) is ideally positioned to address racism in medicine, develop health equity metrics, monitor disparities in clinical performance data, identify research gaps, implement processes and policies to eliminate racial health inequities, and promote anti-racist ideals as advocates for structural change. In this critical review our aim was to (a) provide a synopsis of racial disparities across a broad scope of clinical pathology interests addressed in emergency departments-communicable diseases, non-communicable conditions, and injuries-and (b) through a race-conscious analysis, develop EM practice recommendations for advancing a culture of equity with the potential for measurable impact on healthcare quality and health outcomes.

ABSTRACT

BACKGROUND: Pharmacovigilance agencies did not collect data regarding menstrual changes after COVID-19 vaccination even if many women experienced it. Our aim was to evaluate whether COVID-19 vaccination is associated with secondary changes in menstrual cycle and to assess both quality of life (QoL) and sexual function (SF). METHODS: This study is a retrospective analysis referred to our Department from January 2021 to December 2021. The study cohort responded to same questionnaires before the second dose of vaccination (referring to previous 3 months) and 3 months after that (referring to three menstrual cycles after full-dose vaccination). The surveys administered were FSFI, FSDS, SF-36, MEDI-Q and the VAS-scale for dysmenorrhea. RESULTS: Four-hundred-nineteen vaccinated women were included in the study. The survey did not show a significant change in menstrual cycle length before and after COVID-19 vaccine (5.88±3.67 vs. 4.97±2.89, P=0.21); the interval between periods was significantly higher after a full-cycle vaccination (28.32±7.34 vs. 32.38±7.45, P<0.02); 32 patients (7.6%) developed amenorrhea after the second dose; VAS Scale did not change significantly (median range 3 (3-5) vs. 4 (3-6), P=0.20). MEDI-Q did not show significant variations before and after the vaccination (43.21±11.65 vs. 40.28±9.88, P=0.35). QoL and SF did not change significantly (FSFI median 27 [24-29] vs. 28 [25-30], P=0.12, FSDS median 9 [5-11] vs. 8 [4-12], P=0.22), SF-36 median 81 [70-85] vs. 82 [72-86], P=0.43). CONCLUSIONS: COVID-19 vaccination is associated with a significant change in intervals between menstrual cycles without other alterations in menstrual characteristics, in QoL or SF.

ABSTRACT

We present a theoretical study on the structural and electronic properties of the p-dimethylamino-cinnamaldehyde (DMACA) merocyanine molecule in solvents of different polarities by combining the free energy gradient and the average solvent electrostatic configuration methods via an iterative procedure based on the sequential quantum mechanics/molecular mechanics hybrid methodology. Studying such a system in solution is a crucial step for understanding the solvent effects on its properties, which can have implications in fields such as optoelectronics and biophysics. We found that the DMACA molecule presents different geometries in nonpolar and polar solvents, changing from a polyene-like structure with a pyramidal dimethylamino group (in gas phase or nonpolar solvents) to a cyanine-like structure with a planar dimethylamino group in water due to the stabilizing effect of hydrogen bonds between DMACA and water. The molecular absorption spectrum showed a significant change, increasing solvent polarity with a large shift of the lower energy band, while the other two low lying bands did not shift significantly. The study accurately described the solvatochromic shift of the lowest-energy band and analyzed the structure of the excited states in terms of the one-electron transition density matrix, which showed that the dominant excited state (associated with the first lower energy band) is characterized by a local excitation on the benzene ring with charge transfer character to the carbon conjugated segment.

ABSTRACT

BACKGROUND: The aim of this study was to compare the efficacy of vaginal native tissue repair (VNTR) combined with tension-free transobturator tape (TVT-O) or pelvic floor muscle training (PFMT) in terms of quality of life (QoL) and sexual function (SF) in women affected by anterior defect and occult stress urinary incontinence (OSUI). METHODS: One hundred forty-seven patients with symptomatic anterior defect with OSUI underwent VNTR. In 71 patients TVT-O was inserted and 76 underwent PFMT after surgery. Clinical exam, 3-day voiding diary and urodynamic testing were evaluated in preoperative and postoperative times. Specific questionnaires were also administered, in order to indagate disease perception and the impact on QoL and SF. RESULTS: Nine patients had postoperative pain in the TVT-O group vs. 0 patients in the PMFT group (P=0.001) and 7 patients reported de novo urgency vs. 3 in the two groups, respectively. At 12 weeks follow-up (FU), the first voiding desire was at 88.12+19.70 mL in VNTR+TOT vs. 102.29+19.13 (P=0.03); the mean number of voids (24 hours) was 9.95±2.66 vs. 6.14±1.77 (P=0.04), respectively. No significant differences in terms of QoL and SF were shown. CONCLUSIONS: This retrospective study suggests that VNTR+TVT-O and VNTR+PMFT have the same efficacy in terms of QoL and SF, with several post-operative complications, even if minor, in patients treated with combined surgery.

ABSTRACT

BACKGROUND AND AIMS: Endoscopic eradication therapy (EET) is guideline endorsed for management of early-stage (T1) esophageal adenocarcinoma (EAC). Patients with baseline high-grade dysplasia (HGD) and EAC are at highest risk of recurrence after successful EET, but limited data exist on long-term (>5 year) recurrence outcomes. Our aim was to assess the incidence and predictors of long-term recurrence in a multicenter cohort of patients with T1 EAC treated with EET. METHODS: Patients with T1 EAC achieving successful endoscopic cancer eradication with a minimum of 5 years' clinical follow-up were included. The primary outcome was neoplastic recurrence, defined as dysplasia or EAC, and it was characterized as early (<2 years), intermediate (2-5 years), or late (>5 years). Predictors of recurrence were assessed by time to event analysis. RESULTS: A total of 84 T1 EAC patients (75 T1a, 9 T1b) with a median 9.1 years (range, 5.1-18.3 years) of follow-up were included. The overall incidence of neoplastic recurrence was 2.0 per 100 person-years of follow-up. Seven recurrences (3 dysplasia, 4 EAC) occurred after 5 years of EAC remission. Overall, 88% of recurrences were treated successfully endoscopically. EAC recurrence-related mortality occurred in 3 patients at a median of 5.2 years from EAC remission. Complete eradication of intestinal metaplasia was independently associated with reduced recurrence (hazard ratio, .13). CONCLUSIONS: Following successful EET of T1 EAC, neoplastic recurrence occurred after 5 years in 8.3% of cases. Careful long-term surveillance should be continued in this patient population. Complete eradication of intestinal metaplasia should be the therapeutic end point for EET.

ABSTRACT

Identifying patients' social needs is a first critical step to address social determinants of health (SDoH)-the conditions in which people live, learn, work, and play that affect health. Addressing SDoH can improve health outcomes, population health, and health equity. Emerging SDoH reporting requirements call for health systems to implement efficient ways to identify and act on patients' social needs. Automatic extraction of SDoH from clinical notes within the electronic health record through natural language processing offers a promising approach. However, such automated SDoH systems could have unintended consequences for patients, related to stigma, privacy, confidentiality, and mistrust. Using Floridi et al's "AI4People" framework, we describe ethical considerations for system design and implementation that call attention to patient autonomy, beneficence, nonmaleficence, justice, and explicability. Based on our engagement of clinical and community champions in health equity work at University of Washington Medicine, we offer recommendations for integrating patient voices and needs into automated SDoH systems.

ABSTRACT

INTRODUCTION: Despite literature on a variety of social risks and needs screening interventions in emergency department (ED) settings, there is no universally accepted or evidence-based process for conducting such interventions. Many factors hamper or promote implementation of social risks and needs screening in the ED, but the relative impact of these factors and how best to mitigate/leverage them is unknown. METHODS: Drawing on an extensive literature review, expert assessment, and feedback from participants in the 2021 Society for Academic Emergency Medicine Consensus Conference through moderated discussions and follow-up surveys, we identified research gaps and rated research priorities for implementing screening for social risks and needs in the ED. We identified three main knowledge gaps: 1) screening implementation mechanics; 2) outreach and engagement with communities; and 3) addressing barriers and leveraging facilitators to screening. Within these gaps, we identified 12 high-priority research questions as well as research methods for future studies. RESULTS: Consensus Conference participants broadly agreed that social risks and needs screening is generally acceptable to patients and clinicians and feasible in an ED setting. Our literature review and conference discussion identified several research gaps in the specific mechanics of screening implementation, including screening and referral team composition, workflow, and use of technology. Discussions also highlighted a need for more collaboration with stakeholders in screening design and implementation. Additionally, discussions identified the need for studies using adaptive designs or hybrid effectiveness-implementation models to test multiple strategies for implementation and sustainability. CONCLUSION: Through a robust consensus process we developed an actionable research agenda for implementing social risks and needs screening in EDs. Future work in this area should use implementation science frameworks and research best practices to further develop and refine ED screening for social risks and needs and to address barriers as well as leverage facilitators to such screening.

ABSTRACT

INTRODUCTION: Emergency departments (ED) function as a health and social safety net, regularly taking care of patients with high social risk and need. Few studies have examined ED-based interventions for social risk and need. METHODS: Focusing on ED-based interventions, we identified initial research gaps and priorities in the ED using a literature review, topic expert feedback, and consensus-building. Research gaps and priorities were further refined based on moderated, scripted discussions and survey feedback during the 2021 SAEM Consensus Conference. Using these methods, we derived six priorities based on three identified gaps in ED-based social risks and needs interventions: 1) assessment of ED-based interventions; 2) intervention implementation in the ED environment; and 3) intercommunication between patients, EDs, and medical and social systems. RESULTS: Using these methods, we derived six priorities based on three identified gaps in ED-based social risks and needs interventions: 1) assessment of ED-based interventions, 2) intervention implementation in the ED environment, and 3) intercommunication between patients, EDs, and medical and social systems. Assessing intervention effectiveness through patient-centered outcome and risk reduction measures should be high priorities in the future. Also noted was the need to study methods of integrating interventions into the ED environment and to increase collaboration between EDs and their larger health systems, community partners, social services, and local government. CONCLUSION: The identified research gaps and priorities offer guidance for future work to establish effective interventions and build relationships with community health and social systems to address social risks and needs, thereby improving the health of our patients.

ABSTRACT

OBJECTIVES: Patient and provider-facing screening tools for social determinants of health have been explored in a variety of contexts; however, effective screening and resource referral remain challenging, and less is known about how patients perceive chatbots as potential social needs screening tools. We investigated patient perceptions of a chatbot for social needs screening using three implementation outcome measures: acceptability, feasibility, and appropriateness. METHODS: We implemented a chatbot for social needs screening at one large public hospital emergency department (ED) and used concurrent triangulation to assess perceptions of the chatbot use for screening. A total of 350 ED visitors completed the social needs screening and rated the chatbot on implementation outcome measures, and 22 participants engaged in follow-up phone interviews. RESULTS: The screened participants ranged in age from 18 to 90 years old and were diverse in race/ethnicity, education, and insurance status. Participants (n = 350) rated the chatbot as an acceptable, feasible, and appropriate way of screening. Through interviews (n = 22), participants explained that the chatbot was a responsive, private, easy to use, efficient, and comfortable channel to report social needs in the ED, but wanted more information on data use and more support in accessing resources. CONCLUSION: In this study, we deployed a chatbot for social needs screening in a real-world context and found patients perceived the chatbot to be an acceptable, feasible, and appropriate modality for social needs screening. Findings suggest that chatbots are a promising modality for social needs screening and can successfully engage a large, diverse patient population in the ED. This is significant, as it suggests that chatbots could facilitate a screening process that ultimately connects patients to care for social needs, improving health and well-being for members of vulnerable patient populations.

ABSTRACT

Purpose: When treating esophageal cancer with radiation therapy, it is critical to limit the dose to surrounding structures, such as the lung and/or heart, as much as possible. Proton radiation therapy allows a reduced radiation dose to both the heart and lungs, potentially reducing the risk of cardiopulmonary toxicity. Here, we report disease control, survival, and toxicity outcomes among patients with esophageal cancer treated with proton radiation therapy and concurrent chemotherapy (chemoradiation therapy; CRT) with or without surgery. Materials and Methods: We enrolled 17 patients with thoracic esophageal carcinoma on a prospective registry between 2010 and 2021. Patients received proton therapy to a median dose of 50.4-GyRBE (range, 50.4-64.8) in 1.8-Gy fractions.Acute and late toxicities were graded per the Common Terminology Criteria for Adverse Events, version 4.0 (US National Cancer Institute, Bethesda, Maryland). In addition, disease control, patterns of failure, and survival outcomes were collected. Results: Nine patients received preoperative CRT, and 8 received definitive CRT. Overall, 88% of patients had adenocarcinoma, and 12% had squamous cell carcinoma. With a median follow-up of 2.1 years (range, 0.5-9.4), the 3-year local progression-free, disease-free, and overall survival rates were 85%, 66%, and 55%, respectively. Two patients (1 with adenocarcinoma and 1 with squamous cell carcinoma) recurred at the primary site after refusing surgery after a complete clinical response to CRT. The most common acute nonhematologic and hematologic toxicities, respectively, were grades 1 to 3 esophagitis and grades 1 to 4 leukopenia, both affecting 82% of patients. No acute cardiopulmonary toxicities were observed in the absence of surgical resection. Reagarding surgical complications, 3 postoperative cardiopulmonary complications occurred as follows: 1 grade 1 pleural effusion, 1 grade 3 pleural effusion, and 1 grade 2 anastomotic leak. Two severe late CRT toxicities occurred: 1 grade 5 tracheoesophageal fistula and 1 grade 3 esophageal stenosis requiring a feeding tube. Conclusion: Proton radiation therapy is a safe, effective treatment for esophageal cancer with increasing evidence supporting its role in reducing cardiopulmonary toxicity.

ABSTRACT

OBJECTIVE: To characterize contemporary trends in glucagon fill rates and expenditures in a nationwide cohort of adults with diabetes overall and by key demographic and clinical characteristics. RESEARCH DESIGN AND METHODS: In this retrospective cohort study, we examined 1) glucagon fill rates per 1,000 person-years and 2) patient out-of-pocket and health plan costs per filled glucagon dose among adults with diabetes included in OptumLabs Data Warehouse between 1 January 2011 and 31 March 2021. RESULTS: The study population comprised 2,814,464 adults with diabetes with a mean age of 62.8 (SD 13.2) years. The overall glucagon fill rate decreased from 2.91 to 2.28 per 1,000 person-years (-22%) over the study period. In groups at high risk for severe hypoglycemia, glucagon fill rates increased from 22.46 to 36.76 per 1,000 person-years (64%) among patients with type 1 diabetes, 11.64 to 16.63 per 1,000 person-years (43%) among those treated with short-acting insulin, and 16.08 to 20.12 per 1,000 person-years (25%) among those with a history of severe hypoglycemia. White patients, women, individuals with high income, and commercially insured patients had higher glucagon fill rates compared with minority patients, males, individuals with low income, and Medicare Advantage patients, respectively. Total cost per dosing unit increased from $157.97 to $275.32 (74%) among commercial insurance beneficiaries and from $150.37 to $293.57 (95%) among Medicare Advantage beneficiaries. CONCLUSIONS: Glucagon fill rates are concerningly low and declined between 2011 and 2021 but increased in appropriate subgroups with type 1 diabetes, using short-acting insulin, or with a history of severe hypoglycemia. Fill rates were disproportionately low among minority patients and individuals with low income.

ABSTRACT

BACKGROUND: The aim of this study was to evaluate the efficacy of ospemifene in the Vaginal Health Index (VHI), in the vulvovaginal vascular perfusion, and to assess its impact on quality of life and sexual function. METHODS: Among 52 eligible patients, 43 consecutive postmenopausal patients affected by vulvo-vaginal atrophy (VVA), or genitourinary syndrome (GSM) were evaluated. VVA evaluation and ultrasound of the vulvo-vaginal vascularization by sampling the Pulsatility Index (PI) of clitoris dorsal artery were performed before and after 3 months-treatment with ospemifene. The 36-Item Short Form Survey (SF-36) for the quality-of-life assessment before and after 3 months were available for all women; instead, Female Sexual Function Index (FSFI) and the Female Sexual Distress Scale (FSDS) questionnaires for the sexual function evaluation were performed for sexually active women in the study. The Patient Impression of Global Improvement (PGI-I) after 3 months of treatment was also calculated. RESULTS: The number of sexually active women significantly increased after 3 months (26 [60.46%] vs. 35 [81.39%]; P=0.01). The mean number of intercourses during the treatment increased (12.87±3.43 vs. 15.79±3.12, P=0.03). The PI of clitoris dorsal artery has significantly changed before and after treatment respectively (PI [1.69±0.42 vs. 1.28±0.45, P=0.001] RI [0.74±0.11 vs. 0.54±0.15, P=0.001]). The FSFI, FSDS and SF-36 Questionnaires scores showed a significant improvement after 3 months. VHI and PI were the independent factors of a lower FSFI after 3 months of treatment at multivariate analysis. CONCLUSIONS: Ospemifene improve the VHI and vulvovaginal vascular perfusion demonstrating a positive impact on sexual function and quality of life.

ABSTRACT

BACKGROUND: The aim of this study was to demonstrate that the implementation of remote medical care in the management of patients suffering from specific urogynecological diseases can be a valid alternative to outpatient visits leading to a huge saving of resources which can be used for real emergencies. Therefore, the primary aim of this study was to demonstrate that patients treated with telehealth had the same improvement in symptoms and Quality of Life as those treated with outpatient visits. METHODS: Observational analysis on women with urogynecological diseases was performed during restrictive measures period. One group of patients was assessed in the clinic and one group by video consultations. The population answered Female Sexual Function Index (FSFI), Female Sexual Distress Scale (FSDS), the Overactive Bladder Questionnaire Symptoms and Health-Related Quality of Life Short-Form Symptoms (OAB-Q), Prolapse Quality of Life Questionnaire (P-QoL), the Pelvic Pain and Urinary/Frequency Patient Symptom Scale (PUF) scores, the Short Form Health Survey questionnaires (SF-36) during the first visit and after 12 weeks. The primary endpoint was to evaluate the change in symptoms after the outpatient and telemedicine visit. The secondary endpoint was the evaluation of the telemedicine impact on the Quality of Life and sexual function. RESULTS: One hundred twenty-five patients were considered. Symptoms of overactive bladder, genitourinary syndrome, and recurrent urinary infections improved significantly in both groups with no significant differences. Sexual activity increased significantly in both groups with a significant change in FSFI and FSDS values. The SF-36 showed a significant change 12 weeks after the visit in both groups. CONCLUSIONS: Telemedicine is equally useful and effective as the outpatient visits in patients suffering from urogynecological diseases.

ABSTRACT

INTRODUCTION: Influenza vaccines are commonly provided through community health events and primary care appointments. However, acute unscheduled healthcare visits such as emergency department (ED) visits are increasingly viewed as important vaccination opportunities. Emergency departments may be well-positioned to complement broader public health efforts with integrated vaccination programs. METHODS: We studied an ED-based influenza vaccination initiative in an urban hospital and examined patient-level factors associated with screening and vaccination uptake. Our analyses included patient visits to the ED from October 1, 2019-April 1, 2020. RESULTS: The influenza screening and vaccination program proved feasible. Of the 20,878 ED visits that occurred within the study period, 3,565 (17.1%) included a screening for influenza vaccine eligibility; a small proportion (11.5%) of the patients seen had multiple screenings. Among the patients screened eligible for the vaccine, 916 ultimately received an influenza vaccination while in the ED (43.7% of eligible patients). There was significant variability in the characteristics of patients who were and were not screened and vaccinated. Age, gender, race, preferred language, and receipt of a flu vaccine in prior years were associated with screening and/or receiving a vaccine in the ED. CONCLUSION: Vaccination programs in the ED can boost community vaccination rates and play a role in both preventing and treating current and future vaccine-preventable public health crises, although efforts must be made to deliver services equitably.

ABSTRACT

Tumors are populated by antigen-presenting cells (APCs) including macrophage subsets with distinct origins and functions. Here, we examined how cancer impacts mononuclear phagocytic APCs in a murine model of breast cancer. Tumors induced the expansion of monocyte-derived tumor-associated macrophages (TAMs) and the activation of type 1 dendritic cells (DC1s), both of which expressed and required the transcription factor interferon regulatory factor-8 (IRF8). Although DC1s mediated cytotoxic T lymphocyte (CTL) priming in tumor-draining lymph nodes, TAMs promoted CTL exhaustion in the tumor, and IRF8 was required for TAMs' ability to present cancer cell antigens. TAM-specific IRF8 deletion prevented exhaustion of cancer-cell-reactive CTLs and suppressed tumor growth. Tumors from patients with immune-infiltrated renal cell carcinoma had abundant TAMs that expressed IRF8 and were enriched for an IRF8 gene expression signature. Furthermore, the TAM-IRF8 signature co-segregated with CTL exhaustion signatures across multiple cancer types. Thus, CTL exhaustion is promoted by TAMs via IRF8.
