AbstractBackground and aimsNonalcoholic steatohepatitis (NASH) is associated with metabolic conditions that increase the risk of de novo malignancy following transplant. Patients often have more than one underlying liver disease, which could change the risk of de novo malignancy. This study assessed the incidence of NASH overlap and its effect on de novo malignancy in liver transplant recipients.MethodsData was analyzed from the United Network for Organ Sharing database for all liver transplant recipients from 1997 to 2017 for NASH alone or in combination with another liver disease.ResultsThere is an increasing prevalence of NASH overlap. Of the 98,679 patients included in the analysis, 1238 had a de novo malignancy identified (7.4% by 5 years post‐transplant). The cumulative incidence of de novo malignancy increases in primary sclerosing cholangitis (PSC)/NASH overlap after 5 years and was increased in alcohol‐related liver disease (ALD)/NASH through 10 years compared to ether disease alone. NASH overlaps with “other” diseases experience a cumulative incidence similar to NASH and not the “other” disease. An increased risk of de novo solid organ malignancy was associated with older age, male gender, previous malignancy, and multiorgan transplant.ConclusionThe prevalence of liver transplant recipients with NASH overlap is increasing. These patients may experience different long‐term outcomes than patients with either diagnosis alone. De novo malignancy risk can be influenced by multiple factors and metabolic comorbidities. Further study of patients with overlap diagnoses is important moving forward to guide individualized care and cancer screening programs.

Objective: To determine whether there are differences in asthma management provided in the retail clinic setting versus in the primary care setting, and whether it would increase the number of well controlled asthmatics as determined by ACT score of 20 or greater, and less than or equal to 1 ED or hospital visit due to asthma, within 6 months. Methods: All asthma patients with an asthma control test (ACT) of 19 or less, received a new or updated asthma action plan (AAP) at the visit. If the patient presented to the retail clinic during an asthma exacerbation or with any asthma symptoms, they were not given an ACT and received usual care. Asthma quality data was retrospectively collected for primary care patients seen in the 6-months prior to as well as up to 6 months after the patient’s enrollment visit. Results: There was no significant difference in the number of admissions between locations in either the pre-implementation period or the post-implementation period for either the pediatric or adult cohort. There was a significant improvement in the percentage of pediatric and adult patients with at least 1 ACT in the post-implementation compared to pre-implementation for both retail clinic and primary care sites. The percentage of pediatric and adult patients with at least 1 AAP increased in the post-implementation compared to pre-implementation for both retail clinic and primary care sites. Conclusion: Retail clinics may be able to provide asthma management with similar outcomes to primary care settings.

Background Sedatives are frequently administered in an ICU and are often dependent on patient population and ICU type. These differences may affect patient-centered outcomes. Objective Our primary objective was to identify differences in sedation practice among three different ICU types at an academic medical center. Methods This was a retrospective cross-sectional study of adult patients (≥18 years) requiring a continuous sedative for ≥6 h and admitted to a medical ICU, surgical ICU, and medical/surgical ICU at a single academic medical center in Rochester Minnesota from June 1, 2018 to May 31, 2020. We extracted baseline characteristics; sedative type, dose, and duration; concomitant therapies; and patient outcomes. Summary statistics are presented. Results A total of 2154 patients met our study criteria (1010 from medical ICU, 539 from surgical ICU, 605 from medical/surgical ICU). Propofol was the most frequently used sedative in all ICU settings (74.1% in medical ICU, 53.8% in surgical ICU, 68.9% in medical/surgical ICU, and 67.5% in all ICUs). The mortality rate was highest in the medical/surgical ICU (40.2% in medical ICU, 26.0% in surgical ICU, 40.7% in medical/surgical ICU, and 36.8% in all ICUs). 90.7% of all patients required mechanical ventilation (92.9% in medical ICU, 88.5% in surgical ICU, and 89.1% in medical/surgical ICU). Overall, patients spent more time in light sedation than deep sedation, 75% versus 10.3%, during their ICU admission. Patients in the medical ICU spent a greater proportion of time positive for delirium than the other ICU settings (35.7% in medical ICU, 9.8% in surgical ICU, and 20% in medical/surgical ICU). Similar amounts of opioids (morphine milligram equivalents) were used during the continuous sedative infusion between the three settings. Conclusions We observed that patients in the medical ICU spent more time deeply sedated with multiple agents which was associated with a higher proportion of delirium.

Abstract Objectives Despite low rates of bacterial coinfection in patients admitted with COVID-19, antimicrobials are frequently prescribed. Our primary objective was to evaluate antimicrobial prescribing over time in patients admitted with COVID-19. The secondary objectives were to evaluate the role of ID providers in antimicrobial utilization, describe the rate of confirmed bacterial infection and determine factors associated with empirical antimicrobial prescribing in COVID-19. Materials and methods Retrospective review was performed for adult patients admitted to a tertiary care centre with COVID-19 between 1 March 2020 and 30 November 2020. Patient demographics, disease severity, risk factors for severe disease, clinical outcomes, antimicrobial prescribing and respiratory microbiological testing were collected and analysed. Prescribing trends were evaluated by month, and factors contributing to prescribing were established using univariate and multivariable analysis. Results Antibiotics were prescribed during admission in 37.9% of the study cohort, with 85.1% of patients who received antibiotics having therapy initiated within 48 h of admission. Antibiotic prescribing incidence increased with disease. Over the study period, antimicrobial prescribing rates decreased by 8.7% per month. Multivariable analysis found ICU admission, obtainment of procalcitonin values, intubation, heart failure, haemodialysis and nursing home residence were associated with empirical antimicrobial prescribing. Conclusions Unnecessary antimicrobial prescribing in patients with viral syndromes like COVID-19 continues to represent an area of concern. Antimicrobial stewardship efforts during COVID-19 should consider patient-specific factors associated with antibiotic prescribing. Recognition of such factors, in combination with application of well-established antimicrobial stewardship tactics, may serve to impact antimicrobial prescribing trends, even as patient volumes rise.

Associations of sleep and female sexual function: good sleep quality matters

Menopause | April 21, 2021 | Volume: 28 | Issue: 6 | Pages: 619-625

Abstract Objective: To evaluate associations between sleep and female sexual function. Methods: A cross-sectional analysis from the Data Registry on Experiences of Aging, Menopause and Sexuality (DREAMS) was performed using questionnaires in women presenting for menopause or sexual health consult at Mayo Clinic from December, 2016 to September, 2019. Female Sexual Function Index (FSFI), Female Sexual Distress Scale-Revised (FSDS-R), and the Pittsburgh Sleep Quality Index (PSQI) assessed sexual function and sleep parameters, respectively. Associations between sleep quality (PSQI score ≥ 5 poor sleep quality), sleep durations (< 5 h, 5-6 h, 6-7 h, > 7 h) and female sexual dysfunction (FSFI ≤ 26.55 and FSDS-R ≥ 11) were evaluated utilizing a multivariable logistic model adjusting for multiple factors. A secondary analysis evaluated sleep quality by sexual activity and also included sexually inactive women. Results: A total of 3,433 women were included (mean age 53). Sexually active women (N = 2,487; 72.4%) were included in the primary analysis; 75% had poor sleep quality, and 54% met criteria for female sexual dysfunction. On multivariable analysis, women with poor sleep quality were 1.48 times more likely to report female sexual dysfunction (95% CI 1.21-1.80, P < 0.001). Of women who reported sleeping < 5 hours nightly, 63.3% had female sexual dysfunction, and their Female Sexual Function Index total and domain scores were significantly lower than women sleeping > 7 hours nightly (P = 0.004); however, this was not statistically significant in multivariable analysis. Sexually active women were more likely to report good sleep quality compared with sexually inactive women (25.3% vs 20.5%, P = 0.003). Conclusions: Poor sleep quality, but not sleep duration, was associated with greater odds of female sexual dysfunction. Good sleep quality was linked to sexual activity. In addition to its myriad effects on health, poor sleep quality is associated with female sexual dysfunction. Video Summary: http://links.lww.com/MENO/A714.

Aspirin and statin drugs have been associated with reduced risk of several gastrointestinal cancers, but their association with gallbladder cancer (GBC) has not been well established. We evaluated the association of aspirin and statins with the risk of GBC. Patients with GBC managed at Mayo Clinic between 2000 and 2019 were matched 1:2 with a general patient pool by age and sex. Univariable and multivariable logistic regression models were used to assess associations between GBC and aspirin or statin use. The analysis included 795 cases and 1590 controls, with a median age of 67 years. Aspirin or statin use alone or in combination was higher in controls (p < 0.001). Univariate analysis showed that the use of aspirin [odds ratio (OR): 0.11; 95%CI: 0.08–0.15] or statins (OR: 0.29; 95%CI: 0.20–0.40) and their combined use (OR: 0.18; 95%CI: 0.13–0.24) was associated with lower risk of GBC. Multivariable analysis revealed that aspirin (OR: 0.12; 95%CI: 0.09–0.16) and combined statins and aspirin (OR: 0.46; 95%CI: 0.31–0.67) were associated with lower risk of GBC. Aspirin alone or in combination with statins is associated with a strongly reduced risk of GBC. Further prospective studies are needed to confirm these results and to elucidate their mechanisms.

ABSTRACTThere is a high prevalence of blood-borne infections in West Africa. This study sought to determine the seroprevalence of blood-borne infections, including hepatitis B virus (HBV), hepatitis C virus (HCV), HIV, and syphilis, in blood donors in Burkina Faso. Blood donors were recruited from 2009 to 2013 in four major cities in Burkina Faso of urban area (Ouagadougou) and rural area (Bobo Dioulasso, Fada N’Gourma, and Ouahigouya). Serology tests including hepatitis B surface antigen, anti-HCV, anti-HIV, and rapid plasma reagin test were used for screening and were confirmed with ELISA. Disease prevalence was calculated among first-time donors. Incidence and residual risk were calculated from repeat donors. There were 166,681 donors; 43,084 had ≥ 2 donations. The overall seroprevalence of HBV, HCV, HIV, and syphilis were 13.4%, 6.9%, 2.1%, and 2.4%, respectively. The incidence rates (IRs) of HBV, HCV, HIV, and syphilis infection were 2,433, 3,056, 1,121, and 1,287 per 100,000 person-years. There was lower seroprevalence of HBV and HCV in urban area than in rural area (12.9% versus 14.0%, P < 0.001; and 5.9% versus 8.0%, P < 0.001), and no difference in HIV (2.1% versus 2.1%, P = 0.25). The IRs of new HBV, HCV, HIV, and syphilis were 2.43, 3.06, 1.12, and 1.29 per 100,000 person-years, respectively. The residual risk was one per 268 donations for HBV, one per 181 donations for HCV, and one per 1,480 donations for HIV, respectively. In conclusion, this comprehensive study from four blood donation sites in Burkina Faso showed high HBV and HCV seroprevalence and incidence with high residual risk from blood donation.
Cirrhotic Cardiomyopathy Predicts Posttransplant Cardiovascular Disease: Revelations of the New Diagnostic Criteria

Liver Transplantation | February 5, 2021 | Volume: 27 | Issue: 6 | Pages: 876-886

The diagnostic criteria for cirrhotic cardiomyopathy (CCM) were recently revised to reflect the contemporary advancements in echocardiographic technology. This study evaluates the prevalence of CCM, according to the new criteria, and its impact on posttransplant cardiovascular disease (CVD). This is a single‐center retrospective matched cohort study of liver transplantation (LT) recipients who underwent LT between January 1, 2008 and November 30, 2017. A total of 3 cohorts with decompensated cirrhosis (nonalcoholic steatohepatitis, alcohol‐related liver disease, or other etiologies) were matched based on age, sex, and year of transplant after excluding patients listed without evidence of hepatic decompensation. CCM was defined, according to 2020 criteria, as having diastolic dysfunction, left ventricular ejection fraction ≤50%, and/or a global longitudinal strain (GLS) absolute value <18%. The study echocardiographers were blinded to the clinical data. Posttransplant CVD included new coronary artery disease, congestive heart failure, atrial and ventricular arrhythmia, and stroke. The study included 141 patients of whom 59 were women. The mean age at LT was 57.8 (±7.6) years. A total of 49 patients (34.8%) had CCM. Patients with CCM were at an increased risk for post‐LT CVD (hazard ratio, 2.57; 95% confidence interval, 1.2‐5.5; P = 0.016). Changes in CCM individual parameters pretransplant, such as GLS, early diastolic transmitral flow to early diastolic mitral annular velocity, and left atrial volume index were associated with an increased risk for posttransplant CVD. CCM, defined by the new diagnostic criteria, affects approximately one‐third of decompensated LT candidates. CCM predicts an increased risk for new CVD following LT. Studies into addressing and follow‐up to mitigate these risks are needed.
De Novo Colorectal and Pancreatic Cancer in Liver‐Transplant Recipients: Identifying the Higher‐Risk Populations

Hepatology | February 5, 2021 | Volume: 74 | Issue: 2 | Pages: 1003-1013

Background and Aims Gastrointestinal (GI) malignancies are common after liver transplantation. The aim of this study was to identify the risk and timing of the more common GI malignancies, colorectal and pancreatic cancer, to aid in optimizing potential posttransplant screening practices. Approach and Results Data from the United Network for Organ Sharing database of all adult liver‐transplant recipients from 1997 to 2017 were analyzed and a comparison made with cancer incidence from general population data using Surveillance, Epidemiology, and End Results data. Of 866 de novo GI malignancies, 405 colorectal and 216 pancreas were identified. The highest cumulative incidence for colorectal cancer occurred in recipients with primary sclerosing cholangitis (PSC), recipients over the age of 50 with non‐alcoholic steatohepatitis (NASH) and hepatocellular carcinoma (HCC)/cholangiocarcinoma (CCA), and females >50 years with alcohol‐associated liver disease and HCC/CCA, with risk increasing above the general population within 5 years of transplant. Patients with PSC and HCC/CCA or NASH and HCC/CCA have the highest cumulative incidence of pancreatic cancer also rising within 5 years following transplant, with those patients >50 years old conferring the highest risk. Conclusions These data identify a high‐risk cohort that warrants consideration for intensified individualized screening practices for colorectal cancer after liver transplantation. In addition to recipients with PSC, further study of recipients with NASH and HCC/CCA and females with alcohol‐associated liver disease and HCC/CCA may be better tailored to colorectal cancer screening ideals. Higher‐risk patient populations for pancreatic cancer (PSC and NASH with HCC/CCA) would benefit from further study to determine potential screening practices. GI malignancies occur at higher rates in liver‐transplant patients compared with the general population. In the era of individualized medicine, this study identifies the highest‐risk transplant recipients (PSC and NASH cirrhosis with coexisting HCC/CCA) who may benefit from altered screening practices for these malignancies.
