ABSTRACTObjectivesPrior studies have raised concerns about postpartum hemorrhage (PPH) risk associated with selective serotonin and serotonin‐norepinephrine reuptake inhibitors (SSRIs and SNRIs), although limitations include possible confounding by maternal indications. The current study examined the risk of PPH associated with prenatal S/NRIs accounting for diagnosed maternal depression during pregnancy.MethodsThe current study is a secondary analysis of data from a cohort of 2213 pregnancies (1997–2010) identified from a large electronic medical record‐linkage system. Exposures were identified from electronic prescriptions records and resulted in three main groups: S/NRI‐exposed pregnancies (S/NRI users), antidepressant‐unexposed pregnancies (non‐users), and S/NRI exposure in the year prior to (but not during) pregnancy (former users). Data used to identify PPH occurrences included obstetrician chart diagnoses, diagnosis codes, and recorded estimated blood loss (EBL). The risk of PPH by exposure group was estimated using unadjusted, minimally adjusted (maternal age at delivery, delivery year, parity, and maternal smoking), and depression‐adjusted models (previous covariates and maternal depression). Supplemental analyses included an examination of PPH risk with prenatal bupropion monotherapy.ResultsThe study cohort consisted of 837 S/NRI users, 401 former users, and 786 non‐users, as well as 114 bupropion users identified for additional analyses. The frequency of PPH was 11.6% in the overall cohort, and was 14.7% for S/NRI users, 10.2% for former users, and 8.7% for non‐users. The risk of PPH was significantly higher for S/NRI users than non‐users in unadjusted (OR 1.82 [95% CI 1.33, 2.49]), minimally adjusted (aOR 1.66 [1.19, 2.31]), and depression‐adjusted models (aOR 1.46 [1.02, 2.10]). The risk of PPH was also higher for S/NRI former users than non‐users in unadjusted models (OR 1.54 [1.05, 2.26]) but not minimally adjusted (aOR 1.42 [0.95, 2.11]) or depression‐adjusted models (aOR 1.41 [0.95, 2.10]). No significant differences in PPH risk were observed between S/NRI users and former users, between bupropion users and non‐users, or between S/NRI users and bupropion users.ConclusionsPrenatal S/NRI exposure was associated with an increased risk of PPH after adjusting for maternal depression, although residual confounding and confounding by other factors (including unmeasured factors) may be possible, as the risk of PPH appeared to be similar between S/NRI users and former users. Best‐practice PPH risk management strategies should be adhered to for depressed patients, especially those who require treatment with antidepressants during pregnancy.

Purpose: The prevalence and phenotype of capillaroscopic abnormalities in patients with autonomic nervous system dysfunction have not yet been investigated. Multiorgan involvement in dysautonomia entails abnormal vasoreactivity. We aim to correlate the diagnosis of autonomic dysfunction with certain clinical manifestations, which may provide prognostic or diagnostic information using a noninvasive technique, i.e., nailfold video capillaroscopy (NVC). Methods: Patients with autonomic nervous system dysfunction were recruited from rheumatology and neurology clinics with voluntary NVC procedures from 31 January 2024 to 10 January 2024, and a comparison with normal controls was performed. Additional recorded information include demographics and diagnoses of autonomic dysfunction types by autonomic testing, including, but not limited to, the following: reflex screen, sweat test, Valsalva maneuver, nerve fiber density, electromyography (EMG), serology, and history of autoimmune diseases. NVC was performed on a total of 27 patients. This study was approved by the Mayo Clinic Institutional Review Board. Results: The autonomic dysfunction group consisted of small-fiber neuropathy (37%), orthostatic hypotension (48%), autonomic neuropathy (30%), limited autonomic neuropathy (7%), postural orthostatic tachycardia syndrome (POTS) (7%), and connective tissue disease (7%), among other types. Patients with autonomic dysfunction had statistically significant increases in microhemorrhages, dilated capillaries, and ramifications when compared to controls. Conclusions: Autonomic dysfunction was associated with statistically significant microvascular abnormalities compared to normal controls with a distinct NVC pattern. There was a statistically significant correlation between age and BMI with microvascular abnormalities. Here, we demonstrate the diagnostic potential of NVC in autonomic dysfunction and advocate for further study of capillary structures in autonomic dysfunction.

ImportanceSpecialized ophthalmology terminology limits comprehension for nonophthalmology clinicians and professionals, hindering interdisciplinary communication and patient care. The clinical implementation of large language models (LLMs) into practice has to date been relatively unexplored.ObjectiveTo evaluate LLM–generated plain language summaries (PLSs) integrated into standard ophthalmology notes (SONs) in improving diagnostic understanding, satisfaction, and clarity.Design, Setting, and ParticipantsRandomized quality improvement study conducted from February 1, 2024, to May 31, 2024, including data from inpatient and outpatient encounters in a single tertiary academic center. Participants were nonophthalmology clinicians and professionals and ophthalmologists. The single inclusion criterion was any encounter note generated by an ophthalmologist during the study dates. Exclusion criteria were (1) lack of established nonophthalmology clinicians and professionals for outpatient encounters and (2) procedure-only patient encounters.InterventionAddition of LLM-generated plain language summaries to ophthalmology notes.Main Outcomes and MeasuresThe primary outcome was survey responses from nonophthalmology clinicians and professionals assessing understanding, satisfaction, and clarity of ophthalmology notes. Secondary outcomes were survey responses from ophthalmologists evaluating PLS in terms of clinical workflow and accuracy, objective measures of semantic quality, and safety analysis.ResultsA total of 362 (85%) nonophthalmology clinicians and professionals (33.0% response rate) preferred the PLS to SON. Demographic data on age, race and ethnicity, and sex were not collected. Nonophthalmology clinicians and professionals reported enhanced diagnostic understanding (percentage point increase, 9.0; 95% CI, 0.3-18.2; P = .01), increased note detail satisfaction (percentage point increase, 21.5; 95% CI, 11.4-31.5; P < .001), and improved explanation clarity (percentage point increase, 23.0; 95% CI, 12.0-33.1; P < .001) for notes containing a PLS. The addition of a PLS was associated with reduced comprehension gaps between clinicians who were comfortable and uncomfortable with ophthalmology terminology (from 26.1% [95% CI, 13.7%-38.6%; P < .001] to 14.4% [95% CI, 4.3%-24.6%; P > .06]). PLS semantic analysis found high meaning preservation (bidirectional encoder representations from transformers score mean F1 score: 0.85) with greater readability than SONs (Flesch Reading Ease: 51.8 vs 43.6; Flesch-Kincaid Grade Level: 10.7 vs 11.9). Ophthalmologists (n = 489; 84% response rate) reported high PLS accuracy (90% [320 of 355] a great deal) with minimal review time burden (94.9% [464 of 489] ≤1 minute). PLS error rate on ophthalmologist review was 26% (126 of 489). A total of 83.9% (104 of 126) of errors were deemed low risk for harm and none had a risk of severe harm or death.Conclusions and RelevanceIn this study, use of LLM-generated PLSs was associated with enhanced comprehension and satisfaction among nonophthalmology clinicians and professionals, which might aid interdisciplinary communication. Careful implementation and safety monitoring are recommended for clinical integration given the persistence of errors despite physician review.

There was statistically significant correlation of age and BMI with microvascular abnormalities. We demonstrate diagnostic potential of NVC in autonomic dysfunction and advocate for further study of capillary structure in autonomic dysfunction.

Purpose: Evaluate the relationship between CYP3A4 phenotype, the gene encoding the enzyme that metabolizes exogenous steroids, and the rate of steroid-induced intraocular pressure (IOP) response. Materials and Methods: Lymphocyte-derived DNA sequencing of CYP3A4 from 10073 patients was completed using the PGRN-Seq assay. Subjects with CYP3A4 intermediate metabolizer or slower phenotypes were identified and compared with controls matched by age, race, and sex. All subjects had at least 3 eye exams with at least an exam while on topical/systemic/local steroid in any body location except the eye. Patients with pre-existing glaucoma or glaucoma suspects were excluded. Results: Of the 10,073 patients, there were 63 patients who had CYP3A4 poor or intermediate metabolizer phenotype. Of the 63 patients, 22 had documented steroid use. Fifty-nine percent (13/22) of patients with CYP3A4 poor/intermediate metabolizer had a steroid-induced IOP response of 3 mm Hg or more, significantly higher compared with 23% (5/22) of matched controls (P=0.031). Although more poor/intermediate metabolizers were steroid responders, the average IOP elevation in steroid responders in both groups was similar (5.0±2.5 mm Hg in CYP3A4 poor/intermediate metabolizers compared with 4.1±2.1 mm Hg in controls, P=0.327). Family history of glaucoma was similar in both groups (7/22 vs. 8/22, P=1.0). Conclusion: Reduced CYP3A4 phenotypes may help identify patients at a higher risk of steroid-induced IOP elevation.

Abstract Aims Echocardiographic assessment of cancer-associated non-bacterial thrombotic endocarditis (Ca-NBTE) is limited to case reports and small clinical series. The study aimed to identify heart valve abnormalities and its relation to embolic complications and cancer types. Methods and results Manual review of echocardiographic images and medical records of Mayo Clinic patients (31 March 2002–30 June 2022) was performed. Ca-NBTE in 111 patients (mean age 63.2 ± 9.7 years, 66.7% female) predominantly affected mitral valves (MV) (69), 56 aortic (AV), 8 tricuspid (TV), and rarely pulmonic (PV) (1). In 18 patients, 2 valves were involved, 3 and 4 valve involvement in only a single patient each. Embolic complications were prevalent (n = 102, 91.9%). Ca-NBTE affected MV more frequently on the upstream (atrial) (90% vs. 49.3%) and TV downstream (ventricular) side (75% vs. 37.5%). NBTE size (cm) varied significantly among valves, with TV hosting the largest masses (0.63–2.40 × 0.39–1.77), compared with MV [(0.11–1.81 × 0.11–1.62), (length P = 0.001; width P = 0.03)] and AV [(0.20–2.70 × 0.11–1.51), (length P = 0.001; width P = 0.056)]; MV masses were borderline longer in systemic compared with cerebral emboli (P = 0.057). Majority of MV (79.6%) and AV (69.6%) had thickened leaflets. NBTE lesions commonly affected closing margins (73.9% MV, 85.7% AV, and 62.5% of TV) but rarely commissures of MV (8.7%), yet fairly frequently of AV (41.1%). Five patients had severe regurgitation of MV and 5 AV. Conclusion Ca-NBTE manifests mainly as thrombotic mobile masses attached to thickened MV and AV, with distinct variations in size based on valve type. Embolic destination but not cancer type is associated with NBTE mass size and location.

AbstractBackgroundSimultaneous liver kidney (SLK) transplant protects against acute cellular rejection. In 2017, UNOS implemented a “safety net” policy to allow patients with renal recovery to avoid renal transplantation. Whether kidney after liver transplantation (KALT) increases the risk of rejection is unknown.MethodsWe performed a retrospective analysis of the Organ Procurement and Transplantation Network (OPTN) database of adult patients who received liver transplant, SLK or KALT between 2010 and 2020. We examined rejection of the liver within 6 months and 1 year of the liver transplant, as well as rejection of the kidney within 6 months and 1 year of receiving the kidney, as well as patient and graft loss.ResultsSixty‐six thousand seventy‐nine patients were transplanted; 60 168 with liver transplant alone, 5627 with SLK, and 284 with KALT. Acute or chronic liver rejection rates within 6 or 12 months were statistically higher in the KALT group (10.0% and 10.9%) compared to the SLK group (6.1% and 7.5%), but comparable to the LTA group (9.3% and 11.1%). Kidney rejection and graft survival rates were not different. Liver graft survival was worse in KALT than SLK or LTA (Kaplan‐Meier estimates .61 vs. .89 and .90), but these patients were more ill at the time of transplantation. KDPI and LDRI scores were notably lower in the SLK than KALT group. Patient survival was not clinically different between the groups.ConclusionKALT does not increase the risk of acute or chronic kidney rejection. SLK has a lower risk of early liver rejection, but this effect diminishes by one year to being not clinically different compared to KALT. Given that KALT is immunologically safe, and potentially avoids unnecessary renal graft use, it should be preferred over SLK.Brief summaryPatients undergoing sequential kidney after liver transplant do not have an increased risk of liver or kidney rejection when compared to liver transplant alone or simultaneous liver and kidney transplant.

Abstract Premortem clinical presentation of cancer‐associated non‐bacterial thrombotic endocarditis (Ca‐NBTE), therapy, and the clinal course is limited to case reports and small clinical series. An electronic search of Mayo Clinic records (03/31/2002–06/30/2022) with a subsequent manual review was performed to identify adult patients with echocardiographically detected NBTE and active malignancy, excluding those with infectious endocarditis or lupus anticoagulant/antiphospholipid antibodies. In this retrospective cohort study, we analyzed 115 Ca‐NBTE patients (mean age 63.2 ± 9.7 years, 66.1% female) involving 71 (61.7%) mitral, 58 (50.4%) aortic, 8 (6.9%) tricuspid, and 1 (0.9%) pulmonary valve. The most common cancer was lung ( n = 45 cases (39.1%), followed by pancreatic ( n = 19, 16.5%), gynecological (17, 14.8%), gastrointestinal ( n = 10, 8.7%), and 10 (8.7%) with hematologic malignancy; 6 patients had two active cancers. Embolic complications at presentation were frequent: 94 (81.7%) brain, 11 splenic, 10 renal, 6 coronary, and 4 to the extremities. Of 104 anticoagulated patients, 60 received low molecular weight heparin, 17 unfractionated heparin, 16 apixaban, 8 warfarin, and 3 rivaroxaban. There were 18 arterial thromboembolisms; the Kaplan–Meier estimates of the incidence at 2 years were consistent with a rate of 15.9% [95% Confidence Interval (CI) 9.9–23.3], including 14 strokes (12.4%, 95%CI, 7.1–19.2), and 8 other arterial emboli (10.5%, 95%CI, 4.7–18.9); there were 10 venous thromboembolisms (8.9%, 95%CI, 4.5–15.0). Fourteen major bleedings occurred (12.8%, 95%CI, 7.3–19.9) and 94 patients died during follow‐up (77.9%, 95%CI, 71.1–85.8). Ca‐NBTE predominantly affected women with lung adenocarcinoma or digestive tract cancers and manifested by stroke with high mortality and frequent embolic and bleeding complications during anticoagulation therapy.

Background: Identifying the projected incidence of hepatobiliary cancers and recognizing patient cohorts at increased risk can help develop targeted interventions and resource allocation. The expected incidence of subtypes of hepatobiliary cancers in different age groups, races, and genders remains unknown. Methods: Historical epidemiological data from the Surveillance, Epidemiology, and End Results (SEER) database was used to project future incidence of hepatobiliary malignancies in the United States and identify trends by age, race, and gender. Patients ≥18 years of age diagnosed with a hepatobiliary malignancy between 2001 and 2017 were included. US Census Bureau 2017 National Population projects provided the projected population from 2017 to 2029. Age–Period–Cohort forecasting model was used to estimate future births cohort-specific incidence. All analyses were completed using R Statistical Software. Results: We included 110381 historical patients diagnosed with a hepatobiliary malignancy between 2001 and 2017 with the following subtypes: hepatocellular cancer (HCC) (68%), intrahepatic cholangiocarcinoma (iCCA) (11.5%), gallbladder cancer (GC) (8%), extrahepatic cholangiocarcinoma (eCCA) (7.6%), and ampullary cancer (AC) (4%). Our models predict the incidence of HCC to double (2001 to 2029) from 4.5 to 9.03 per 100,000, with the most significant increase anticipated in patients 70–79 years of age. In contrast, incidence is expected to continue to decline among the Asian population. Incidence of iCCA is projected to increase, especially in the white population, with rates in 2029 double those in 2001 (2.13 vs. 0.88 per 100,000, respectively; p < 0.001). The incidence of GC among the black population is expected to increase. The incidence of eCCA is expected to significantly increase, especially among the Hispanic population, while that of AC will remain stable. Discussion: The overall incidence of hepatobiliary malignancies is expected to increase in the coming years, with certain groups at increased risk. These findings may help with resource allocation when considering screening, treatment, and research in the coming years.
