The ability to make informed decisions about reproductive health is a cornerstone principle of the practice of prenatal medical genetics. Unfortunately, these reproductive health decisions have become entangled in the current, contentious political climate. This debate reached an inflection point in 2022 with Dobbs v. Jackson when the Supreme Court of the United States (SCOTUS) overturned the national right to abortion previously established in Roe v. Wade. This decision prompted a reassessment of the opinions of medical students on reproductive health and abortion. Our study focused on a medical school in Alabama, a conservative state that enacted a restrictive abortion ban following the Dobbs ruling. Two surveys, conducted in 2015 and 2022, explored students' viewpoints on reproductive health topics, including abortion. The comparison revealed a significant shift toward more pro-choice perspectives among medical students. Notably, religious affiliation did not consistently align with opinions, as many Christian students supported pro-choice views. Our results suggest that medical students' reproductive health opinions at our institution have shifted to a more pro-choice position over the last decade.

OBJECTIVE
To investigate the incidence and risk factors of acute kidney injury (AKI) stage 3 in adult patients under veno-arterial extracorporeal membrane oxygenation (VA-ECMO) support.
DESIGN
A retrospective case-control study.
SETTING
Single center, Fuwai Hospital.
PARTICIPANTS
Adult VA-ECMO patients age ≥18 years and older treated between January 2020 and December 2022 were included.
INTERVENTIONS
The patients were grouped by whether they developed AKI Kidney Disease: Improving Global Outcomes (KDIGO) stage 3 or <3. Multivariate logistic regression was performed t"o evaluate risk factors of AKI stage 3.
MEASUREMENTS AND MAIN RESULTS
Among enrolled patients, 40 (53.3%) developed AKI stage 3. The in-hospital mortality of AKI stage 3 patients was significantly higher than that of AKI stage <3 patients (67.5% vs 34.3%; p = 0.004). Multivariate logistic regression analysis revealed that concomitant hypertension (odds ratio [OR], 0.250; 95% confidence interval [CI], 0.063, 0.987), p = 0.048), pre-ECMO hemoglobin (OR, 0.969; 95% CI, 0.947-0.992; p = 0.009), pre-ECMO lactate (OR, 1.173; 95% CI, 1.028-1.339; p = 0.018), and pre-ECMO creatinine (OR, 1.014; 95% CI, 1.003-1.025; p = 0.011) were independent risk factors for AKI stage 3.
CONCLUSIONS
This study found a high incidence (53.3%) of AKI stage 3 in adult patients with VA-ECMO support and an association with increased in-hospital mortality. Concomitant hypertension, low pre-ECMO hemoglobin, and elevated pre-ECMO lactate and pre-ECMO creatinine were independent risk factors for AKI stage 3 in patients receiving VA-ECMO. It is imperative to identify and adjust these risk factors to enhance outcomes for those supported by VA-ECMO.

Ophthalmology. Retina Jun 2024To demonstrate the therapeutic similarity of CT-P42 compared to reference aflibercept (Eylea®) in adult patients with diabetic macular edema (DME).
OBJECTIVE
To demonstrate the therapeutic similarity of CT-P42 compared to reference aflibercept (Eylea®) in adult patients with diabetic macular edema (DME).
DESIGN
Randomized, active-controlled, double-masked, Phase III clinical trial PARTICIPANTS: Patients with a diagnosis of either type 1 or 2 diabetes mellitus (DM) with DME involving the center of the macula.
METHODS
Patients were randomized (1:1) to receive either CT-P42 or reference aflibercept (2 mg/0.05 mL) by intravitreal injection every 4 weeks (5 doses) then every 8 weeks (4 doses) in the main study period. Results up to Week 24 are reported herein.
MAIN OUTCOME MEASURES
The primary endpoint was mean change from baseline at Week 8 in best corrected visual acuity (BCVA) using the Early Treatment Diabetic Retinopathy Study (ETDRS) chart. Equivalence between CT-P42 and reference aflibercept was to be concluded if the two-sided 95% confidence interval (CI) (global assumptions) and two-sided 90% CI (US Food and Drug Administration [FDA] assumptions) for the treatment difference fell entirely within the equivalence margin of ±3 letters, as assessed in the full analysis set.
RESULTS
Overall, 348 patients were randomized (CT-P42: 173; reference aflibercept: 175). BCVA improved from baseline to Week 8 in both groups, with a least squares mean (standard error) improvement of 9.43 (0.798) and 8.85 (0.775) letters in the CT-P42 and reference aflibercept groups, respectively. The estimated between-group treatment difference was 0.58 letters, with the CIs within the pre-defined equivalence margin of ±3 letters (95% CI -0.73, 1.88 [global]; 90% CI -0.52, 1.67 [FDA]). Through Week 24, other efficacy results for the two groups, in terms of change in BCVA and retinal central subfield thickness, as well as ETDRS Diabetic Retinopathy Severity Scale score, supported therapeutic similarity. Pharmacokinetics, usability, safety (including the proportions of patients experiencing at least one treatment-emergent adverse event [CT-P42: 50.3%; reference aflibercept: 53.7%]), and immunogenicity were also comparable between groups.
CONCLUSIONS
This study in patients with DME demonstrated equivalence between CT-P42 and reference aflibercept (2 mg/0.05 mL) in terms of efficacy, with similar pharmacokinetic, usability, safety, and immunogenicity profiles.

OBJECTIVES
In the endovascular aneurysm repair (EVAR) era, open surgical repair (OSR) is performed for ruptured abdominal aorta aneurysm (RAAA) in patients with complex aneurysm neck and technical difficulties. Understanding the risk factors of OSR is essential for the clinical selection of the ideal surgical procedure. We aimed to re-evaluate the outcomes of OSR and treatment options for RAAA.
METHODS
Patients who underwent OSR for RAAA between January 2010 and December 2022 were enrolled in this single-center, retrospective observational study. Preoperative status, operative findings, and postoperative course were retrospectively reviewed. The Cox proportional hazards model was used to evaluate the association between age and early postoperative mortality.
RESULTS
Among 142 patients, 43 (30.3%) and 99 (69.7%) were aged ≥80 and <80 years, respectively. Postoperative mortality within 30 days occurred in 24 (16.9%) patients (11/43 [25.6%] and 13/99 [13.1%] patients aged ≥80 and <80 years, respectively; hazard ratio [HR]=1.95; P=0.069). In a multivariable analysis, increased postoperative mortality within 30 days was associated with age ≥80 years (adjusted HR, aHR=2.36; P=0.049), the presence of pre- or intraoperative cardiopulmonary arrest (aHR=12.0; P<0.001), and postoperative gastrointestinal disorder (aHR=4.42; P=0.003).
CONCLUSIONS
EVAR may be preferable in older people; however, its use in cases of pre- or intraoperative cardiopulmonary arrest or perioperative gastrointestinal disorders remains controversial, and a careful discussion on the surgical indications is needed in such cases.

Review
OBJECTIVES
Endovascular aortic repair requires extensive preoperative, intraoperative, and postoperative imaging for planning, surveillance, and detection of endo-leaks. There have been many advancements in imaging modalities to achieve this purpose. This review discussed different imaging modalities used at different stages of treatment of complex endovascular aortic repair.
METHODS
We conducted a literature review of all the imaging modalities utilized in endovascular aortic repair by searching various databases.
RESULTS
Pre-operative techniques include analysis of images obtained via modified central line using analysis software and intravascular ultrasound. Fusion imaging, CO2 angiography, intravascular ultrasound, and Fiber Optic RealShape technology have been crucial in obtaining real-time imaging for the detection of endo-leaks during operative procedures. Conventional imaging modalities like CT Angiography and MR Angiography are still employed for post-operative surveillance along with computational fluid dynamics and contrast-enhanced ultrasound. The advancements in artificial intelligence have been the breakthrough in developing robust imaging applications.
CONCLUSIONS
This review explains the advantages, disadvantages, and side-effect profile of the abovementioned imaging modalities.

BACKGROUND AND AIMS
Computer-aided diagnosis (CADx) for optical diagnosis of colorectal polyps is thoroughly investigated. However, studies on human-artificial intelligence (AI) interaction are lacking. Aim was to investigate endoscopists' trust in CADx by evaluating whether communicating a calibrated algorithm confidence improved trust.
METHODS
Endoscopists optically diagnosed 60 colorectal polyps. Initially, endoscopists diagnosed the polyps without CADx assistance (initial diagnosis). Immediately afterwards, the same polyp was again shown with CADx prediction; either only a prediction (benign or pre-malignant) or a prediction accompanied by a calibrated confidence score (0-100). A confidence score of 0 indicated a benign prediction, 100 a (pre-)malignant prediction. In half of the polyps CADx was mandatory, for the other half CADx was optional. After reviewing the CADx prediction, endoscopists made a final diagnosis. Histopathology was used as gold standard. Endoscopists' trust in CADx was measured as CADx prediction utilization; the willingness to follow CADx predictions when the endoscopists initially disagreed with the CADx prediction.
RESULTS
Twenty-three endoscopists participated. Presenting CADx predictions increased the endoscopists' diagnostic accuracy (69.3% initial vs 76.6% final diagnosis, p<0.001). The CADx prediction was utilized in 36.5% (n=183/501) disagreements. Adding a confidence score led to a lower CADx prediction utilization, except when the confidence score surpassed 60. A mandatory CADx decreased CADx prediction utilization compared to an optional CADx. Appropriate trust, utilizing correct or disregarding incorrect CADx predictions was 48.7% (n=244/501).
CONCLUSIONS
Appropriate trust was common and CADx prediction utilization was highest for the optional CADx without confidence scores. These results express the importance of a better understanding of human-AI interaction.

BACKGROUND CONTEXT
Extreme Lateral Interbody Fusion (XLIF) has been established as an effective treatment for degenerative disorders of the lumbar spine. Nevertheless, there is a potential risk of lumbar plexus damage associated with XLIF, especially during surgeries at the L4-5 segment. Diffusion Tensor Imaging (DTI) evaluates the directional diffusion of water molecules in tissue, providing a more intricate depiction of internal tissue microstructure compared to conventional MRI techniques. The capability of DTI sequences to elucidate the three-dimensional interplay between lumbar nerve pathways and adjacent musculoskeletal structures, potentially reducing the incidence of nerve injury complications related to XLIF, remains to be established.
PURPOSE
This study evaluates the effectiveness of preoperative Diffusion Tensor Imaging (DTI) in reducing neurological complications after Extreme Lateral Interbody Fusion (XLIF) surgeries at the L4-5 level, focusing on the interaction between lumbar nerves and the psoas major muscle.
STUDY DESIGN
Retrospective case-control study.
PATIENT SAMPLE
The study included 128 patients undergoing XLIF surgery for degenerative disorders at the L4-5 segment: 68 in the traditional group and 62 in the DTI group.
OUTCOME MEASURES
The study assessed Visual Analogue Scale (VAS) and Oswestry Disability Index (ODI) scores, along with complication rates. It also documented psoas major muscle morphology and its correlation with nerve pathways.
METHODS
A retrospective analysis of 128 patients undergoing XLIF surgery for degenerative disorders at the L4-5 segment between February 2020 and August 2022 was conducted. The cohort was divided into a traditional group (68 patients) receiving pre-surgery MRI scans to identify surgical entry points at the intervertebral space midpoint (Zones II-III junction) and a DTI group (62 patients) who additionally underwent preoperative DTI to customize entry points. The study evaluated VAS and ODI scores, complication rates, psoas major muscle morphology, and its interaction with nerve pathways.
RESULTS
The traditional group uniformly chose the Zone II-III junction for entry. In contrast, the DTI group's entry points varied. Postoperative follow-up revealed significant improvements in VAS and ODI scores in both groups. However, the DTI group experienced fewer immediate postoperative complications such as thigh pain, numbness, and motor disturbances. The study also noted a ventral shift in nerve positioning in patients with elevated psoas muscles.
CONCLUSIONS
Preoperative DTI effectively maps the relationship between the psoas major muscle and lumbar nerves. Tailoring surgical entry points based on DTI results significantly reduces the risk of nerve damage in XLIF surgeries. The study underscores the importance of recognizing variability in lumbar nerve pathways due to differing psoas muscle morphologies, highlighting a higher risk of nerve injury in patients with elevated psoas muscles during XLIF procedures.

INTRODUCTION
Total knee arthroplasty (TKA) is performed on approximately 790,000 patients annually in the United States and is projected to increase to 1.5 million by 2050. This study aimed at assessing the use of preoperative cryoneurolysis on patients undergoing TKA by analyzing: 1) pain severity; 2) opioid use; 3) functional status; and 4) sleep disturbance over 6 months following discharge.
METHODS
Patients enrolled in the Innovations in Genicular Outcomes Registry (iGOR) between September 2021 and February 2024 were followed for 6 months. Our analyses included patients undergoing unilateral primary TKA with no pre-operative opioid prescription who either received, or did not receive, cryoneurolysis. Baseline patient demographics were collected before TKA and tabulated. Pain management was assessed via the Brief Pain Inventory-Short Form (BPI-SF) instrument for pain severity. Sleep disturbance was measured using the Patient-Reported Outcomes Measurement Information System (PROMIS) questionnaire. Each outcome measure was assessed prior to TKA, weekly, and at monthly follow-up. Data was analyzed by a generalized linear mixed-effect regression model to compare cryoneurolysis versus control patients, with a P < 0.05 as significant.
RESULTS
There were 80 patients who were treated with preoperative cryoneurolysis, while 60 control patients did not have treatment. Patients receiving cryoneurolysis experienced significantly lower pain severity and sleep disturbance over the 6-month follow-up than control patients (P = 0.046). Cryoneurolysis was also associated with a trend toward greater functional improvement that did not reach statistical significance (P = 0.061). Further, patients who underwent cryoneurolysis were 72% less likely than controls to take opioids over six months following discharge (P <0.001).
CONCLUSIONS
Pre-operative cryoneurolysis therapy in opioid-naïve patients undergoing TKA is associated with improved pain, decreased opioid use, and improved sleep disturbance for 6 months postoperatively. Cryoneurolysis, a non-opioid pain relief modality administered pre-operatively, demonstrated substantial benefits in patients who underwent TKA.

INTRODUCTION
Adverse Childhood Experiences (ACE) are associated with the development of negative health behaviors and medical illness. ACE's association with poor health outcomes has been well documented in the general population; however, this relationship remains less clear in liver transplant (LT) recipients. The aims of this study therefore were to determine the prevalence of ACE and the influence of ACE on LT outcomes.
METHODS
A retrospective electronic medical record review of all LT recipients over 11 years at an academic liver transplant center. Demographic, diagnostic, and disease characteristics were extracted and compared for a history of ACE. Associations between a history of ACE and extracted variables were statistically tested using Student's t-test and Chi-square tests or Fisher's Exact Test where appropriate. Graft and patient survival were tested using log-rank tests.
RESULTS
Of 1,172 LT recipients, 24.1% endorsed a history of ACE. Females (p = 0.017) and recipients with lower level of education (p < 0.001) had a higher frequency of ACE. Those with a history of ACE had a higher prevalence of HCV (p < 0.001) and higher pre-transplant BMI (P<0.001). Recipients with a history of ACE had higher prevalence of mood (p < 0.001), anxiety (p < 0.001), PTSD (p < 0.001), alcohol use (p < 0.001), and cannabis use (p < 0.001) disorders as well has higher PHQ-9 (p < 0.001) and GAD-7 (p < 0.001) scores pre and post-transplant. Those with ACE had higher incidence of recorded relapse to alcohol by 3 years post-transplant (p = 0.027). Mean lab values, graft survival, and patient survival were not significantly different between those with and without a history of ACE except for total bilirubin at 6 months (p = 0.021).
CONCLUSION
One quarter of LT recipients have experienced ACE. ACE was associated with a history of a psychiatric diagnoses, substance use disorders, elevated PHQ-9 and GAD-7 scores, and a higher prevalence of relapse to alcohol use after transplant. This population may benefit from increased/improved access to appropriate mental health and substance use services and support in the peri and post transplant period.

Review
Parkinson's disease (PD), the second most common neurodegenerative disorder, is characterized by loss of dopaminergic neurons in the substantia nigra, as well as the abnormal accumulation of misfolded α-synuclein. Clinically, PD is featured by typical motor symptoms and some non-motor symptoms. Up to now, although considerable progress has been made in understanding the pathogenesis of PD, there is still no effective therapeutic treatment for the disease. Thus, exploring new therapeutic strategies has been a topic that needs to be addressed urgently. Noteworthy, with the proposal of the microbiota-gut-brain axis theory, antimicrobial drugs have received significant attention due to their effects on regulating the intestinal microbiota. Nowadays, there is growing evidence showing that some antimicrobial drugs may be promising drugs for the treatment of PD. Data from pre-clinical and clinical studies have shown that some antimicrobial drugs may play neuroprotective roles in PD by modulating multiple biochemical and molecular pathways, including reducing α-synuclein aggregation, inhibiting neuroinflammation, regulating mitochondrial structure and function, as well as suppressing oxidative stress. In this paper, we summarized the effects of some antimicrobial drugs on PD treatment from recent pre-clinical and clinical studies. Then, we further discussed the potential of a few antimicrobial drugs for treating PD based on molecular docking and molecular dynamics simulation. Importantly, we highlighted the potential of clorobiocin as the therapeutic strategy for PD owing to its ability to inhibit α-synuclein aggregation. These results will help us to better understand the potential of antimicrobial drugs in treating PD and how antimicrobial drugs may alleviate or reverse the pathological symptoms of PD.
