BACKGROUND
Posthepatectomy liver failure remains a potentially life-threatening complication after hepatectomy. Soluble suppression of tumourigenicity 2 is an injury-related biomarker. The aim of the study was to assess soluble suppression of tumourigenicity 2 elevation after hepatectomy and whether it can predict posthepatectomy liver failure.
METHODS
This was a single-centre retrospective study including all patients who underwent a liver resection between 2015 and 2019. Plasma concentrations of soluble suppression of tumourigenicity 2 were measured before surgery and at postoperative days 1, 2, 5 and 7. Posthepatectomy liver failure was defined according to the International Study Group of Liver Surgery and the morbidity rate was graded according to the Clavien-Dindo classification.
RESULTS
A total of 173 patients were included (75 underwent major and 98 minor resection); plasma levels of soluble suppression of tumourigenicity 2 increased from 43.42 (range 18.69-119.96) pg/ml to 2622.23 (range 1354.18-4178.27) pg/ml on postoperative day 1 (P < 0.001). Postoperative day 1 soluble suppression of tumourigenicity 2 concentration accurately predicted posthepatectomy liver failure ≥ grade B (area under curve = 0.916, P < 0.001) and its outstanding performance was not affected by underlying disease, liver pathological status and extent of resection. The cut-off value, sensitivity, specificity, positive predictive value and negative predictive value of postoperative day 1 soluble suppression of tumourigenicity 2 in predicting posthepatectomy liver failure ≥ grade B were 3700, 92%, 85%, 64% and 97% respectively. Soluble suppression of tumourigenicity 2high patients more frequently experienced posthepatectomy liver failure ≥ grade B (64.3% (n = 36) versus 2.6% (n = 3)) and Clavien-Dindo IIIa higher morbidity rate (23.2% (n = 13) versus 5.1% (n = 6)) compared with soluble suppression of tumourigenicity 2low patients.
CONCLUSIONS
Soluble suppression of tumourigenicity 2 may be a reliable predictor of posthepatectomy liver failure ≥ grade B as early as postoperative day 1 for patients undergoing liver resection. Its role in controlling hepatic injury/regeneration needs further investigation. Registration number: ChiCTR-OOC-15007210 (www.chictr.org.cn/).

Immunosuppression constitutes a significant risk for community-acquired pneumonia (CAP). Nevertheless, specific causes of immunosuppression and their relevance for incidence, etiology and prognosis of CAP are insufficiently investigated.We conducted a population-based cohort study within a statutory health insurance in Germany from 2015 to 2018. CAP was retrieved by ICD-10-GM codes. Episodes of immunosuppression were identified by coded conditions (hematologic neoplasms, stem cell or organ transplantation, neutropenia, HIV, primary immunosuppressive syndromes) or treatments (immunosuppressants, antineoplastic drugs, systemic steroids). Endpoints were defined as occurrence of CAP (primary), hospitalization, 30-day mortality and CAP associated with rare pathogens. Our analysis utilized the Andersen-Gill model adjusted for sex, age, level of long-term care, vaccination status, community type and comorbidities.942,008 individuals with 54,781 CAPs were included (hospitalization 55%, 30-day mortality 14.5%). 6% of individuals showed at least one episode of immunosuppression during the study period with systemic steroids (39.8%) and hematologic neoplasms (26.7%) being most common. Immunosuppression was recorded in 7.7% of CAPs. Besides classical risk factors such as age and level of long-term care, immunosuppressed patients were most prone to CAP (HR 2.4[2.3-2.5]) and consecutive death (HR 1.9[1.8-2.1]). Organ and stem cell transplantation (HR 3.2[2.6-4.0] and 2.8[2.1-3.7], respectively), HIV (HR 3.2[1.9-5.4]) and systemic steroids (> 20 mg prednisone daily dose equivalent (HR 2.7[2.4-3.1])) showed the highest risk for contracting CAP. CAP by rare pathogens was strongly associated with immunosuppression (HR 17.1[12.0-24.5]), especially HIV (HR 34.1[7.6-153]) and systemic steroids (HR 8.2[4.6-14.8]).Our study elucidates the relevance of particular immunosuppressive conditions including systemic steroids for occurrence and prognosis of CAP.

BACKGROUND
Metabolic dysfunction-associated steatotic liver disease (MASLD) is highly prevalent in people with obesity. We aimed to study the association of body mass index (BMI) with clinical outcomes in patients with MASLD.
METHODS
A retrospective cohort of 32,900 patients with MASLD, identified through the International Classification of Diseases-9 and 10 codes within the electronic health records of a large US-based health system, with a mean follow-up of 5.5 years (range: 1-15 y), was stratified into 6 BMI categories, <25, 25-<30, 30-<40, 40-<50, and ≥50 kg/m2.
RESULTS
The risk of liver decompensation and extrahepatic obesity-associated cancers had a J-shaped profile (both ps for linear and quadratic terms <0.05). Compared to patients with BMI 25-<30 kg/m2, the adjusted HRs (95% CIs) for liver decompensation of patients with BMI <25 and BMI ≥50 kg/m2 were 1.44 (1.17-1.77) and 2.27 (1.66-3.00), respectively. The corresponding figures for obesity-associated extrahepatic cancer were 1.15 (0.97-1.36) and 1.29 (1.00-1.76). There was an inverse association for BMI with liver transplantation and non-obesity-associated cancer (both ps for linear terms <0.05), but no association with HCC or all types of cancers combined. A similar J-shaped association between BMI and all-cause mortality was observed; adjusted HRs (95% CIs) for BMI <25 and ≥50 kg/m2 were 1.51 (1.32-1.72) and 3.24 (2.67-3.83), respectively, compared with BMI 25-<30 kg/m2 (both ps for linear and quadratic terms <0.001).
CONCLUSIONS
Patients with MASLD and very severe obesity (BMI ≥50 kg/m2) had the highest risk, exceeding that of patients with lean MASLD, for developing liver decompensation, obesity-associated extrahepatic cancers, or dying from any cause.

BACKGROUND
Kidney transplantation is a complex process requiring extensive preparation and ongoing monitoring. Artificial intelligence (AI)-powered chatbots hold potential for providing accessible health information, but our understanding of their role in offering health advice for kidney transplantation and how individuals assess such advice remains limited. This study investigates how individuals evaluate ChatGPT's responses to kidney transplantation questions in terms of information quality and empathy, focusing on potential differences across race/ethnicity and educational backgrounds.
METHODS
We collected Reddit posts (N = 4624) regarding kidney transplantation and selected 86 questions to represent typical clinician inquiries. These questions were used as input prompts for ChatGPT. A total of 565 participants assessed ChatGPT's responses through online surveys, rating information quality and empathy using Likert scales.
RESULTS
Multilevel analyses (N = 2825) show that there is a significant interaction between race/ethnicity and education levels in various measures related to perceived information quality, but not perceived empathy of ChatGPT's responses: accuracy (p < 0.05); authenticity (p < 0.01); believability (p < 0.05); informativeness (p = 0.053); usefulness (p < 0.05); recognizing users' feelings (p = 0.70) and understanding feelings and situations (p = 0.65). Among non-White individuals, higher education levels predicted higher perceived quality of ChatGPT's responses across all information quality measures. Notably, this trend was reversed for White individuals, where higher education levels led to lower perceived information quality.
CONCLUSIONS
Our results highlight the importance of developing AI tools sensitive to diverse communication styles and information needs.

Kidney organoids - 3D representations of kidneys made either from pluripotent or tissue stem cells - have been available for well over a decade. Their application could confer notable benefits over longstanding in vivo approaches with the potential for clinically aligned human cells and reduced ethical burdens. They been used, at a proof-of-concept level, in development in disease modeling (including with patient-derived stem cells), and in screening drugs for efficacy/toxicity. They differ from real kidneys: they represent only foetal-stage tissue, in their simplest forms they lack organ-scale anatomical organization, they lack a properly arranged vascular system, and include non-renal cells. Cell specificity may be improved by better techniques for differentiation and/or sorting. Sequential assembly techniques that mimic the sequence of natural development, and localized sources of differentiation-inducing signals, improve organ-scale anatomy. Organotypic vascularization remains a challenge: capillaries are easy, but the large vessels that should serve them are absent from organoids and, even in cultured real kidneys, these large vessels do not survive without blood flow. Transplantation of organoids into hosts results in their being vascularized (though probably not organotypically) and in some renal function. It will be important to transplant more advanced organoids, with a urine exit, in the near future to assess function more stringently. Transplantation of human foetal kidneys, followed by nephrectomy of host kidneys, keeps rats alive for many weeks, raising hope that, if organoids can be produced even to the limited size and complexity of foetal kidneys, they may one day be useful in renal replacement.

AIMS
Urogynecology and Reconstructive Pelvic Surgery (URPS) fellowship can be pursued after completion of either a urology (URO) or obstetrics and gynecology (GYN) residency. Our aim is to determine differences in graduating fellow cohort (GFC) case logs between URO- and GYN-based URPS programs.
METHODS
Accreditation Council for Graduate Medical Education case logs for URPS GFCs in both GYN- and URO-based programs were analyzed for the 2019-2023 academic years (AY). Unpaired t-tests with Welch's correction were used to compare annual mean logged cases between URO- versus GYN-based GFCs for select surgical categories and the top 11 most logged index cases.
RESULTS
GYN-based GFCs logged more cases for all pelvic organ prolapse (POP) categories including surgery on apical POP, anterior wall POP, and posterior wall POP (all p < 0.01), while URO-based GFCs logged more cases for surgery on the urinary system (p = 0.03). For the top 11 logged procedures, URO-based GFCs logged more sacral neuromodulation cases (p = 0.02), whereas GYN-based GFCs logged more slings, vaginal hysterectomies, minimally-invasive hysterectomies, vaginal apical POP, vaginal posterior POP, vaginal anterior POP, and minimally-invasive apical POP cases (all p < 0.01). There was no difference between URO- and GYN-based GFCs for complex urodynamics, cystoscopy with botox injection, or periurethral injection cases.
CONCLUSIONS
URO-based URPS fellows tend to graduate with more surgery on the urinary system and sacral neuromodulation cases, while GYN-based fellows perform more slings, hysterectomies, and POP surgery. These findings may help fellowships better understand potential differences in training among graduates from URO- and GYN-based programs and encourage collaboration to lessen these discrepancies.
