Rates Among Hospitalized Patients With COVID-19 Treated With Convalescent Plasma: A Systematic Review and Meta-Analysis.

Objective: To examine the association of COVID-19 convalescent plasma transfusion with mortality and the differences between subgroups in hospitalized patients with COVID-19. Patients and Methods: On October 26, 2022, a systematic search was performed for clinical studies of COVID-19 convalescent plasma in the literature from January 1, 2020, to October 26, 2022. Randomized clinical trials and matched cohort studies investigating COVID-19 convalescent plasma transfusion compared with standard of care treatment or placebo among hospitalized patients with confirmed COVID-19 were included. The electronic search yielded 3841 unique records, of which 744 were considered for full-text screening. The selection process was performed independently by a panel of 5 reviewers. The study followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Data were extracted by 5 independent reviewers in duplicate and pooled using an inverse-variance random effects model. The prespecified end point was all-cause mortality during hospitalization. Results: Thirty-nine randomized clinical trials enrolling 21,529 participants and 70 matched cohort studies enrolling 50,160 participants were included in the systematic review. Separate meta-analyses reported that transfusion of COVID-19 convalescent plasma was associated with a decrease in mortality compared with the control cohort for both randomized clinical trials (odds ratio [OR], 0.87; 95% CI, 0.76-1.00) and matched cohort studies (OR, 0.76; 95% CI, 0.66-0.88). The meta-analysis of subgroups revealed 2 important findings. First, treatment with convalescent plasma containing high antibody levels was associated with a decrease in mortality compared with convalescent plasma containing low antibody levels (OR, 0.85; 95% CI, 0.73 to 0.99). Second, earlier treatment with COVID-19 convalescent plasma was associated with a decrease in mortality compared with the later treatment cohort (OR, 0.63; 95% CI, 0.48 to 0.82). Conclusion: During COVID-19 convalescent plasma use was associated with a 13% reduced risk of mortality, implying a mortality benefit for hospitalized patients with COVID-19, particularly those treated with convalescent plasma containing high antibody levels treated earlier in the disease course.

Avoiding Blunders When Analyzing Correlated Data, Clustered Data, or Repeated Measures.

Rheumatology research often involves correlated and clustered data. A common error when analyzing these data occurs when instead we treat these data as independent observations. This can lead to incorrect statistical inference. The data used are a subset of the 2017 study from Raheel et al consisting of 633 patients with rheumatoid arthritis (RA) between 1988 and 2007. RA flare and the number of swollen joints served as our binary and continuous outcomes, respectively. Generalized linear models (GLM) were fitted for each, while adjusting for rheumatoid factor (RF) positivity and sex. Additionally, a generalized linear mixed model with a random intercept and a generalized estimating equation were used to model RA flare and the number of swollen joints, respectively, to take additional correlation into account. The GLM's ß coefficients and their 95% confidence intervals (CIs) are then compared to their mixed-effects equivalents. The ß coefficients compared between methodologies are very similar. However, their standard errors increase when correlation is accounted for. As a result, if the additional correlations are not considered, the standard error can be underestimated. This results in an overestimated effect size, narrower CIs, increased type I error, and a smaller P value, thus potentially producing misleading results. It is important to model the additional correlation that occurs in correlated data.

Prediction of permanent pacemaker implantation after transcatheter aortic valve replacement: The role of machine learning.

BACKGROUND: Atrioventricular block requiring permanent pacemaker (PPM) implantation is an important complication of transcatheter aortic valve replacement (TAVR). Application of machine learning could potentially be used to predict pre-procedural risk for PPM. AIM: To apply machine learning to be used to predict pre-procedural risk for PPM. METHODS: A retrospective study of 1200 patients who underwent TAVR (January 2014-December 2017) was performed. 964 patients without prior PPM were included for a 30-d analysis and 657 patients without PPM requirement through 30 d were included for a 1-year analysis. After the exclusion of variables with near-zero variance or ≥ 50% missing data, 167 variables were included in the random forest gradient boosting algorithm (GBM) optimized using 5-fold cross-validations repeated 10 times. The receiver operator curve (ROC) for the GBM model and PPM risk score models were calculated to predict the risk of PPM at 30 d and 1 year. RESULTS: Of 964 patients included in the 30-d analysis without prior PPM, 19.6% required PPM post-TAVR. The mean age of patients was 80.9 ± 8.7 years. 42.1 % were female. Of 657 patients included in the 1-year analysis, the mean age of the patients was 80.7 ± 8.2. Of those, 42.6% of patients were female and 26.7% required PPM at 1-year post-TAVR. The area under ROC to predict 30-d and 1-year risk of PPM for the GBM model (0.66 and 0.72) was superior to that of the PPM risk score (0.55 and 0.54) with a P value < 0.001. CONCLUSION: The GBM model has good discrimination and calibration in identifying patients at high risk of PPM post-TAVR.

Food-Specific IgG4 Is Elevated Throughout the Upper Gastrointestinal Tract in Eosinophilic Esophagitis.

BACKGROUND: Food-specific immunoglobulin G4 (FS-IgG4) is associated with eosinophilic esophagitis (EoE); however, it is not clear whether production is limited to the esophagus. AIMS: To assess FS-IgG4 levels in the upper gastrointestinal tract and plasma and compare these with endoscopic disease severity, tissue eosinophil counts, and patient-reported symptoms. METHODS: We examined prospectively banked plasma, throat swabs, and upper gastrointestinal biopsies (esophagus, gastric antrum, and duodenum) from control (n = 15), active EoE (n = 24), and inactive EoE (n = 8) subjects undergoing upper endoscopy. Patient-reported symptoms were assessed using the EoE symptom activity index (EEsAI). Endoscopic findings were evaluated using the EoE endoscopic reference score (EREFS). Peak eosinophils per high-power field (eos/hpf) were assessed from esophageal biopsies. Biopsy homogenates and throat swabs were normalized for protein content and assessed for FS-IgG4 to milk, wheat, and egg. RESULTS: Median FS-IgG4 for milk and wheat was significantly increased in the plasma, throat swabs, esophagus, stomach, and duodenum of active EoE subjects compared to controls. No significant differences for milk- or wheat-IgG4 were observed between active and inactive EoE subjects. Among the gastrointestinal sites sampled, FS-IgG4 levels were highest in the esophagus. Esophageal FS-IgG4 for all foods correlated significantly across all sites sampled (r ≥ 0.59, p < 0.05). Among subjects with EoE, esophageal FS-IgG4 correlated significantly with peak eos/hpf (milk and wheat) and total EREFS (milk). EEsAI scores and esophageal FS-IgG4 levels did not correlate. CONCLUSIONS: Milk and wheat FS-IgG4 levels are elevated in plasma and throughout the upper gastrointestinal tract in EoE subjects and correlate with endoscopic findings and esophageal eosinophilia.

Impact of Glomerulitis on Long-term Outcomes After Kidney Transplantation.

The Banff classification scheme provides a framework for interpreting transplant kidney biopsies and has undergone various updates in the past 2 decades especially related to antibody-mediated rejection. The clinical significance of early glomerulitis seen within 4 mo on protocol biopsies has received limited attention. We hypothesized that early glomerulitis seen on protocol biopsies will lead to significant adverse outcomes as assessed by histopathology and allograft outcome. Methods: A single-center retrospective study of a cohort of patients who underwent protocol biopsies within 4 mo after transplantation with timely follow-up protocol biopsies were assessed. Patients with recurrent glomerulonephritis were excluded. Results: We calculated glomerulitis (g) scores for 2212 biopsy specimens and identified 186 patients with glomerulitis (g > 0) and 2026 patients without glomerulitis (g = 0). The progression to chronic transplant glomerulopathy at 1 and 2 y was higher in patients with g > 0 as compared with g = 0 (year 1, 10.7% versus 2.3% [P < 0.001]' respectively; year 2, 17.2% versus 4.3% [P < 0.001], respectively) with no difference in other chronic lesions. The death-censored graft failure rate was higher in patients with g > 0 as compared with g = 0 (hazard ratio, 1.68 [95% CI, 1.07-2.65]; P = 0.02). We did not find any difference in outcomes in glomerulitis group based on donor-specific antibody. Conclusion: Our findings suggest that early glomerulitis (seen within 4 mo after transplantation) may lead to clinically significant long-term changes and thus could be a target for early intervention therapies.

Patient Versus Caregiver: Correlation and Differences in Pediatric Quality of Life Using a Prospective Registry in a Large-Volume, Multisite Practice.

PURPOSE: Patient-reported outcomes provide quality of life (QOL) data during and after radiation. When pediatric patients are unable to complete patient-reported outcomes, it is unknown whether caregiver responses are an accurate surrogate. We assessed whether caregiver scores for the Pediatric Quality of Life Inventory (PedsQL) Core and Brain Tumor Module questionnaires can substitute for missing child scores. METHODS AND MATERIALS: From 2016 to 2018, pediatric patients treated with radiation were followed in a prospective, institutional registry. Child and caregiver Core and Tumor PedsQL surveys were obtained at pretreatment, end of treatment, and in regular follow-up. The differences between the 2 scores at each time point were quantified using a linear mixed-model and the level of agreement was estimated with intraclass correlation coefficient (ICC). An ICC 95% confidence interval (CI) lower limit exceeding 0.75 was considered an acceptable threshold for using caregiver scores as imputed values for missing child scores. RESULTS: Ninety-one children completed 403 surveys. Caregivers underestimated QOL scores at baseline, but not at end of treatment or any follow-up time. The PedsQL Core total score had an ICC of 0.88 (95% CI, 0.81-0.92), and the emotional, physical, school, and social function subdomain scores were 0.81 (0.72-0.88), 0.72 (0.58-0.82), 0.79 (0.68-0.86), and 0.75 (0.62-0.83), respectively. The tumor total score ICC was 0.91 (0.85, 0.94), and each of the subdomains (cognitive problems, communication, movement and balance, nausea, pain and hurt, perceived physical appearance, procedural anxiety, treatment anxiety, and worry) had ICC lower bound 95% CI ≥0.75 except for communication (0.83, 0.74-0.89). Bland-Altman analysis demonstrated no visual change in discrepancy between child and caregiver estimates as overall QOL improved. CONCLUSIONS: Agreement between child- and caregiver-reported QOL was generally strong in the acute period after radiation, implying that caregiver scores may be imputed for child scores in future protocols and analyses of pediatric QOL.

Impact of timing of preoperative gabapentin administration on postoperative somnolence.

CONTEXT: Enhanced Recovery After Surgery (ERAS) is a multimodal protocol aimed to improve quality of postoperative recovery, minimize complications, and optimize overall self-regulation. Preoperative gabapentin decreases postoperative pain but can be associated with prolonged postoperative somnolence and respiratory depression risk. Although it is known that gabapentin affects the postoperative course, it is unclear if the timing of preoperative administration affects this finding. OBJECTIVES: This study aims to assess the optimal preoperative timing for gabapentin administration in patients undergoing gynecologic surgery to minimize postoperative somnolence risk. METHODS: A retrospective cohort study evaluated patients who underwent major gynecologic surgery and received preoperative gabapentin. Patients were grouped based on timing from gabapentin administration to surgical incision (<4 h group vs. ≥4 h group). Preoperative, intraoperative, and postoperative data were abstracted and compared. Univariate associations between the timing of gabapentin administration and the patient and surgical characteristics and outcomes were tested utilizing two-sample equal-variance t-tests, linear model ANOVA, or Fisher's exact tests. Associations between the timing of gabapentin administration and the time until the Richmond Agitation Sedation Scale (RASS) score of 0 were modeled utilizing linear regression, adjusted for age, initial postoperative anesthesia care unit (PACU), RASS score, and postoperative narcotics. RESULTS: Each group contained 127 patients. Demographics were similar except for age (<4 h group mean=44.2 years; ≥4 h group mean=40.5 years; p=0.021), chronic pain (<4 h group=17.6%; ≥4 h group=43.3%; p<0.001), and surgical indication (<4 h group=pelvic pain [29.1%]; ≥4 h group=pelvic pain [51.2%]; p=0.007). The <4 h group had a similar postoperative narcotic administration (<4 h group mean morphine milligram equivalents [MME]=3.667; ≥4 h group mean MME=4.833; p=0.185). The minutes from surgical closure until the patient received a RASS score of 0 and initial PACU pain score (Visual Analogue Scale [VAS]) were similar. The initial PACU oxygen administration volume, hours from surgical closure until the patient transitioned to room air, and initial PACU respiratory rate were similar. The PACU duration, admission secondary to somnolence, and initial PACU Glasgow Coma Scale (GCS) score showed no difference. Postoperative nausea/vomiting was decreased in the ≥4 h group (<4 h group=24.4%; ≥4 h group=13.4%; p-value=0.036), and urinary retention (<4 h group=14.2%; ≥4 h group=5.5%; p-value=0.033) was decreased in the ≥4 h group. CONCLUSIONS: The timing of gabapentin administration less than or more than 4 h preoperatively in patients ≥18 years does not significantly affect postoperative somnolence or respiratory depression. Further, it does not have a significant effect on GCS scores or VAS scores.

A Comparison of Perceived Lifetime Breast Cancer Risk to Calculated Lifetime Risk Using the Gail Risk Assessment Tool.

Background: Understanding the accuracy of a woman's perceived breast cancer risk can enhance shared decision-making about breast cancer screening through provider and patient discussion. We aim to report and compare women's perceived lifetime breast cancer risk to calculated lifetime breast cancer risk. Methods: Women presenting to Mayo Clinic in Arizona and Minnesota in July 2016 completed a survey assessing their perceived breast cancer risk. Lifetime Gail risk scores were calculated from questions pertaining to health history and were then compared with perceived breast cancer risk. Results: A total of 550 predominantly white, married, and well-educated (≥college) women completed surveys. Using lifetime Gail risk scores, 5.6% were classified as high risk (>20% lifetime risk), 7.7% were classified as intermediate risk (15%-20%), and 86.6% were classified as average risk (<15%). Of the 27 women who were classified as high risk, 18 (66.7%) underestimated their risk and of the 37 women who were intermediate risk, 12 (32.4%) underestimated risk. Women more likely to underestimate their risk had a reported history of an abnormal mammogram and at least one or more relative with a history of breast cancer. Surveyed women tended to overestimate risk 4.3 (130/30) times as often as they underestimated risk. Conclusion: In a group of predominantly white, educated, and married cohort of women, there was a large portion of women in the elevated risk groups who underestimated risk. Specific aspects of medical history were associated with underestimation including a history of abnormal mammogram and family history of breast cancer. Overall, in our sample, more women overestimated than underestimated risk.

Access to and safety of COVID-19 convalescent plasma in the United States Expanded Access Program: A national registry study.

BACKGROUND: The United States (US) Expanded Access Program (EAP) to coronavirus disease 2019 (COVID-19) convalescent plasma was initiated in response to the rapid spread of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the causative agent of COVID-19. While randomized clinical trials were in various stages of development and enrollment, there was an urgent need for widespread access to potential therapeutic agents. The objective of this study is to report on the demographic, geographical, and chronological characteristics of patients in the EAP, and key safety metrics following transfusion of COVID-19 convalescent plasma. METHODS AND FINDINGS: Mayo Clinic served as the central institutional review board for all participating facilities, and any US physician could participate as a local physician-principal investigator. Eligible patients were hospitalized, were aged 18 years or older, and had-or were at risk of progression to-severe or life-threatening COVID-19; eligible patients were enrolled through the EAP central website. Blood collection facilities rapidly implemented programs to collect convalescent plasma for hospitalized patients with COVID-19. Demographic and clinical characteristics of all enrolled patients in the EAP were summarized. Temporal patterns in access to COVID-19 convalescent plasma were investigated by comparing daily and weekly changes in EAP enrollment in response to changes in infection rate at the state level. Geographical analyses on access to convalescent plasma included assessing EAP enrollment in all national hospital referral regions, as well as assessing enrollment in metropolitan areas and less populated areas that did not have access to COVID-19 clinical trials. From April 3 to August 23, 2020, 105,717 hospitalized patients with severe or life-threatening COVID-19 were enrolled in the EAP. The majority of patients were 60 years of age or older (57.8%), were male (58.4%), and had overweight or obesity (83.8%). There was substantial inclusion of minorities and underserved populations: 46.4% of patients were of a race other than white, and 37.2% of patients were of Hispanic ethnicity. Chronologically and geographically, increases in the number of both enrollments and transfusions in the EAP closely followed confirmed infections across all 50 states. Nearly all national hospital referral regions enrolled and transfused patients in the EAP, including both in metropolitan and in less populated areas. The incidence of serious adverse events was objectively low (<1%), and the overall crude 30-day mortality rate was 25.2% (95% CI, 25.0% to 25.5%). This registry study was limited by the observational and pragmatic study design that did not include a control or comparator group; thus, the data should not be used to infer definitive treatment effects. CONCLUSIONS: These results suggest that the EAP provided widespread access to COVID-19 convalescent plasma in all 50 states, including for underserved racial and ethnic minority populations. The study design of the EAP may serve as a model for future efforts when broad access to a treatment is needed in response to an emerging infectious disease.

Menopausal symptoms in the Southwest United States: A cross-sectional survey of women from areas with different socioeconomic resources.

OBJECTIVE: Menopausal symptoms may differ by geography and ethnicity, but the impact of socioeconomic factors is less clear. The purpose of this study was to compare menopausal symptoms in women from areas of Arizona with different socioeconomic resources. STUDY DESIGN: Women aged 40-65 years in two cohorts were surveyed: (1) Phoenix women attending either a clinic for patients who are uninsured or a clinic for people experiencing homelessness; and (2) Scottsdale women living in zip codes with higher average income and neighborhood advantage (surveyed by mail). Surveys included the Greene Climacteric Scale (GCS) and demographic questions. MAIN OUTCOME MEASURES: GCS score by domain and subdomain, corrected for age, race, menopause stage and menopausal hormone therapy (HT). RESULTS: Phoenix participants (N = 104) were 51.2 years old (SD 6.45), Hispanic (54.4%), White (28.2%) or African American (8.7%), and uninsured (53.0%). Scottsdale participants (N = 151) were 52.6 years old (SD 5.52), mostly White (94.7%) and insured (100%). Three percent of Phoenix women were on HT vs. 23.3% in Scottsdale (p < 0.001). Multivariate analysis revealed higher total GCS scores in the Phoenix vs. Scottsdale cohort (39.13 vs 30.14, p < 0.001), which was also seen in the psychological and somatic domains, as well as the anxiety and depression subdomains. No statistically significant differences were seen in the vasomotor or sexual dysfunction domains. CONCLUSION: In a group of women living in Arizona from distinct socioeconomic areas, significant differences were demonstrated in menopausal symptom bother specifically with higher psychological and somatic symptoms in women who were uninsured or experiencing homelessness independent of age, race, menopause stage and HT use. Future studies controlling for co-morbidities associated with lower socioeconomic status such as depression would provide further insight into this population of midlife women.

Sex and gender specific health topics in medical student learners: pulse check eight years later.

BACKGROUND: An essential component of patient-centered, individualized medicine is considering how sex and gender affect mechanisms of health and disease. OBJECTIVES: To assess medical students' current knowledge of sex and gender specific health (SGSH) concepts compared to results from the same survey in 2012 to better inform development of curricular materials for medical education. METHODS: A previously designed survey tool, which assessed current knowledge of sex and gender-based medicine of medical students, was emailed to all Mayo Clinic Alix School of Medicine (MCASOM) students on Minnesota, Arizona, and Florida campuses in 2020. Descriptive and qualitative thematic results were compared to the same survey administered in 2012 to students enrolled in MCASOM. Changes in the inclusion of SGSH topics were assessed over the eight years. RESULTS: One hundred and one of 365 (27.7% response rate) surveys were returned with 2:1 female to male respondents with representation from all 4 years. The definitions of the terms "sex" and "gender" were correctly identified by most respondents (93.1%). However, only 36% (12/33) of questions related to other medical knowledge on SGSH topics had more than a 50% correct response rate. More than half of the students reported that SGSH topics were included in Gynecology, Cardiology, Pediatrics, and Immunology. SGSH topics were reported as not being routinely covered in Neurology and Nephrology, although more students said they were in 2020 then 2012. Sixty-two percent of students favored increasing SGSH in the current curriculum. CONCLUSIONS: Medical students appear to understand the definition of and importance of SGSH in education. While some improvements in coverage by subject matter and topic area appear to have occurred as reported by medical students, opportunity remains to more fully integrate SGSH concepts in medical school curricula.

Low-Dose Ketamine Infusion for Perioperative Pain Management in Patients Undergoing Laparoscopic Gastric Bypass: A Prospective Randomized Controlled Trial.

INTRODUCTION: Obesity is a common comorbidity seen in the perioperative setting and is associated with many diseases including cardiovascular disease and obstructive sleep apnea. Laparoscopic Roux-en-Y gastric bypass is the gold standard surgical treatment for patients whose weight is refractory to diet and exercise. Caring for these patients perioperatively presents unique challenges to anesthesiologists and is associated with an increased risk of adverse respiratory events. In our study, we hypothesize that a low-dose perioperative ketamine infusion will reduce opioid consumption and improve analgesia when compared to standard therapy. METHODS: This is a single-center, prospective randomized controlled study enrolling 35 patients in total. Patients were randomized equally into the ketamine and control group. Preop, intraop, and postop management regimens were standardized. The ketamine group received a 0.3 mg/kg ideal body weight ketamine bolus after induction followed by a 0.2 mg/kg/hr ketamine infusion continued into the postop setting for up to 24 hours. Data collected included total perioperative opioids used converted to oral morphine equivalents (ME), pain scores, side effects, hospital length of stay, and patient satisfaction captured via postoperative questionnaires. RESULTS: The use of perioperative opioid consumption was significantly lower in the ketamine group when compared with the control group (179.9 ME versus 248.7 ME, P=0.03). There was no statistically significant difference in pain scores or hospital length of stay postoperatively between the two groups. There were also no reported adverse respiratory events, prolonged sedation, agitation, or other side effects reported in either group. The patient satisfaction questionnaires showed a significant difference with the ketamine group reporting lower maximum pain scores, a decrease in how pain limited activities of daily living once discharged, and increased hospital pain management satisfaction scores. CONCLUSIONS: Perioperative low-dose ketamine infusions significantly reduced opioid consumption in morbidly obese patients undergoing laparoscopic gastric bypass surgery.

Mortality in individuals treated with COVID-19 convalescent plasma varies with the geographic provenance of donors.

Successful therapeutics and vaccines for coronavirus disease 2019 (COVID-19) have harnessed the immune response to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Evidence that SARS-CoV-2 exists as locally evolving variants suggests that immunological differences may impact the effectiveness of antibody-based treatments such as convalescent plasma and vaccines. Considering that near-sourced convalescent plasma likely reflects the antigenic composition of local viral strains, we hypothesize that convalescent plasma has a higher efficacy, as defined by death within 30 days of transfusion, when the convalescent plasma donor and treated patient were in close geographic proximity. Results of a series of modeling techniques applied to approximately 28,000 patients from the Expanded Access to Convalescent Plasma program (ClinicalTrials.gov number: NCT04338360) support this hypothesis. This work has implications for the interpretation of clinical studies, the ability to develop effective COVID-19 treatments, and, potentially, for the effectiveness of COVID-19 vaccines as additional locally-evolving variants continue to emerge.

Engaging the opioid epidemic head on: Improving proper disposal of unused opioid medications after surgery.

BACKGROUND: Currently, in the United States, there is an epidemic of opioid abuse. While this problem is well known to the public due to significant media and political attention, patients are poorly educated on the proper handling and disposal of unused opioids. Instead, the onus has fallen on the healthcare provider to minimize the number of opioids prescribed. STUDY OBJECTIVE: To improve proper opioid disposal rates after gynecologic surgery by providing educational materials along with a disposal bag. STUDY DESIGN: We performed a prospective study evaluating baseline understanding of medication disposal using a questionnaire given to the patients during their preoperative visit. Subsequently, patients were provided written information on proper disposal of their medications and an activated charcoal medication disposal bag. Study patients completed a survey about disposal of their unused opioids at their last post-operative visit. The success of education and proper disposal of opioid medications were evaluated. RESULTS: Thirty-five patients, average age of 45 (range 20-77), were enrolled, and 31 patients successfully completed both surveys. The surgeries performed included hysterectomy 23 percent (n = 7), laparoscopic excision of endometriosis 32 percent (n = 10), laparoscopic ovarian cystectomy 23 percent (n = 7), prolapse repair 3 percent (n = 1), and midurethral sling procedures 19 percent (n = 6). Chronic pelvic pain was identified in 39 percent (n = 12) of our patient population. Prior to education, 52 percent (n = 16) of patients did not dispose of their opioids. Furthermore, 71 percent (n = 22) of patients stated they had never been educated by a medical provider regarding appropriate disposal. Nineteen percent (n = 6) confirmed they have used an opioid medication prescribed to someone else. Demographic data show 65 percent (n = 20) of these patients had completed a college degree or greater. After education and being given a reliable option for medication disposal with the Deterra® bag, 94 percent (n = 29) of patients properly disposed of their opioids after surgery, demonstrating a 45 percent (p < 0.001) increase in proper disposal. In our study alone, 491 tablets of 5mg oxycodone were properly disposed. The majority of patients, 77 percent (n = 24) used the drug disposal bag, and when queried, stated they would be willing to pay on average $7.70 (range 0-20) per bag. Without education and a simple option for disposal, 422 tablets prescribed may have been subject to inappropriate diversion. CONCLUSION: This study clearly shows that patient education, coupled with a reliable option for opioid disposal, is effective. We strongly encourage other surgical institutions to implement similar practices not only for our surgical patients' safety, but also for the tens of thousands of patients who died of opioid abuse in the last year.

Differences in menopausal symptoms and female sexual function by region and ethnicity in West Texas and Central Arizona: a cross-sectional survey.

OBJECTIVE: To evaluate menopausal symptoms and sexual problems in Hispanic and non-Hispanic women in two Southwest areas. METHODS: An anonymous survey including the Green Climacteric Scale (GCS), Female Sexual Function Index (FSFI), and demographics was distributed to English and Spanish-speaking women age 40 to 60 in Scottsdale, Arizona, and West Texas. FSFI for sexually active women and GCS scores for the Hispanic and non-Hispanic women in Texas were analyzed with multivariable analysis and compared between Texas and Arizona for Non-Hispanic participants. RESULTS: Predominantly non-Hispanic women (70%), average age 51.5 (SD = 7.25) completed questionnaires (199 West Texas, 163 Scottsdale). A majority of sexually active women (88%) were found to be at risk of sexual dysfunction. Within the Texas cohort, GCS score was estimated to be 3.49 points lower (less symptoms) in Hispanic versus non-Hispanic participants [95% CI -6.58 to -0.40, P = 0.03], and FSFI score was estimated to be 2.31 points lower (more symptoms) in Hispanic versus non-Hispanic participants [95% CI -4.49 to -0.14, P = 0.04]. Among non-Hispanic women, GCS scores were lower (less symptoms) in Texas versus Arizona by 10.25 points [95% CI -14.83 to -5.66, P < 0.01], while FSFI scores were higher overall (less symptoms) in Texas by 3.65 points [95% CI 0.53-6.77), P = 0.02]. All FSFI and GCS scores were adjusted for multiple variables. CONCLUSIONS: In a group of menopausal women from the Southwest, most reported symptoms were consistent with FSD, and the degree of sexual problems appeared to be greater in the Hispanic participants from Texas.

Diagnosis of Pediatric Non-Esophageal Eosinophilic Gastrointestinal Disorders by Eosinophil Peroxidase Immunohistochemistry.

BACKGROUND: Diagnosis of non-esophageal eosinophilic gastrointestinal disorders requires quantification of tissue eosinophils. Our objective was to evaluate eosinophil peroxidase (EPX) immunohistochemistry (IHC) as a method for histologic diagnosis of eosinophilic gastritis (EG) and eosinophilic duodenitis (EoD). METHODS: We performed a retrospective analysis of biopsies from pediatric EG/EoD cases and controls. Subjects with EG or EoD had ≥30 eosinophils per high power field (eos/hpf) in ≥5 hpf in the stomach and/or ≥3 hpf in the duodenum, respectively. Controls had no histopathologic diagnosis recorded. Tissue eosinophil counts were assessed by hematoxylin & eosin stains. EPX stains were assessed using a unique histopathologic scoring system. Slides were digitized and EPX+ staining area/mm2 was quantified by image analysis. RESULTS: Twenty-six EG/EoD cases and 40 controls were analyzed. EPX scores and EPX/mm2 levels were markedly elevated in EG/EoD (p ≤ 0.0001). Eosinophil density (eos/mm2) correlated strongly with EPX scores and EPX/mm2 levels in the stomach (r ≥ 0.77) and moderately with EPX scores and EPX/mm2 levels in the duodenum (r ≥ 0.52); (p < 0.0001). EPX quantification identified EG/EoD subjects with high diagnostic accuracy (EPX score: AUC = 1 for EG and EoD; EPX/mm2: AUC = 0.98 (95%CI 0.96-1) for EG, AUC = 0.91 (95%CI 0.81-1) for EoD). CONCLUSION: EPX-based assessment of eosinophilic inflammation may facilitate automated histologic diagnosis.

Implications of neuroendocrine tumor and diabetes mellitus on patient outcomes and care: a matched case-control study.

AIM: We aimed to determine the impact of diabetes mellitus (DM) on survival of patients with neuroendocrine tumors (NETs) and of NETs on glycemic control. PATIENTS & METHODS: Patients with newly diagnosed NETs with/without DM were matched 1:1 by age, sex and diagnosis year (2005-2017), and survival compared (Kaplan-Meier and Cox proportional hazards). Mixed models compared hemoglobin A1c (HbA1c) and glucose during the year after cancer diagnosis. RESULTS: Three-year overall survival was 72% (95% CI: 60-86%) for DM patients versus 80% (95% CI: 70-92%) for non-DM patients (p = 0.82). Hazard ratio was 1.33 (95% CI: 0.56-3.16; p = 0.51); mean DM HbA1c, 7.3%. CONCLUSION: DM did not adversely affect survival of patients with NET. NET and its treatment did not affect glycemic control.

Program and patient characteristics for the United States Expanded Access Program to COVID-19 convalescent plasma.

BACKGROUND: The United States (US) Expanded Access Program (EAP) to COVID-19 convalescent plasma was initiated in response to the rapid spread of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the causative agent of coronavirus disease-2019 (COVID-19). While randomized clinical trials were in various stages of development and enrollment, there was an urgent need for widespread access to potential therapeutic agents particularly for vulnerable racial and ethnic minority populations who were disproportionately affected by the pandemic. The objective of this study is to report on the demographic, geographic, and chronological access to COVID-19 convalescent plasma in the US via the EAP. METHODS AND FINDINGS: Mayo Clinic served as the central IRB for all participating facilities and any US physician could participate as local physician-principal investigator. Registration occurred through the EAP central website. Blood banks rapidly developed logistics to provide convalescent plasma to hospitalized patients with COVID-19. Demographic and clinical characteristics of all enrolled patients in the EAP were summarized. Temporal trends in access to COVID-19 convalescent plasma were investigated by comparing daily and weekly changes in EAP enrollment in response to changes in infection rate on a state level. Geographical analyses on access to convalescent plasma included assessing EAP enrollment in all national hospital referral regions as well as assessing enrollment in metropolitan and less populated areas which did not have access to COVID-19 clinical trials.From April 3 to August 23, 2020, 105,717 hospitalized patients with severe or life-threatening COVID-19 were enrolled in the EAP. A majority of patients were older than 60 years of age (57.8%), male (58.4%), and overweight or obese (83.8%). There was substantial inclusion of minorities and underserved populations, including 46.4% of patients with a race other than White, and 37.2% of patients were of Hispanic ethnicity. Severe or life-threatening COVID-19 was present in 61.8% of patients and 18.9% of patients were mechanically ventilated at time of convalescent plasma infusion. Chronologically and geographically, increases in enrollment in the EAP closely followed confirmed infections across all 50 states. Nearly all national hospital referral regions enrolled patients in the EAP, including both in metropolitan and less populated areas. CONCLUSIONS: The EAP successfully provided widespread access to COVID-19 convalescent plasma in all 50 states, including for underserved racial and ethnic minority populations. The efficient study design of the EAP may serve as an example framework for future efforts when broad access to a treatment is needed in response to a dynamic disease affecting demographic groups and areas historically underrepresented in clinical studies.
