ABSTRACT Background Microbial overgrowth (MO) in the small intestine can cause gastrointestinal symptoms and may arise from stasis, such as dysmotility. Microtypes of MO include small intestinal bacterial overgrowth (SIBO) and intestinal methanogen overgrowth (IMO). Dyssynergic defecation (DD) is associated with constipation and slow colonic transit (STC). Our aim was to assess the relationship between DD and MO. Methods We retrospectively identified patients who underwent both anorectal manometry (ARM) and balloon expulsion testing (BET) for DD, and MO testing using either small intestinal aspirate culture or breath testing. SIBO was analyzed using two culture thresholds: ≥ 10 5 CFU/mL and ≥ 10 3 CFU/mL. Chi‐square tests compared positive vs. negative results. Key Results 436 patients underwent culture of SB aspirates. At the ≥ 10 5 CFU/mL threshold, 41.7% were diagnosed with SIBO, and 87.4% at ≥ 10 3 CFU/mL. At ≥ 10 5 CFU/mL, percent anal relaxation was significantly lower in SIBO‐positive patients. SIBO patients were more likely to have reduced anal relaxation ( p = 0.032), but no other ARM parameters or BET > 60 s. At ≥ 10 3 CFU/mL, a more negative recto‐anal pressure differential (RAPD) was observed, along with a combination of RAPD < −45 mmHg and resting anal pressure > 90 mmHg. 637 patients underwent breath testing for MO, with 174 positive results, predominantly showing IMO (73%). In this group, BET was significantly longer, and anal relaxation was significantly lower. SIBO at ≥ 10 3 CFU/mL was more prevalent in DD than STC (85.5% vs. 64.7%, p = 0.002). IMO was more common in DD than STC ( p = 0.021). Conclusion/Inferences DD may be a risk factor for MO, often with evidence of methanogenesis.

Background The management of unruptured intracranial aneurysms (UIA) requires a balance between procedural risks and the potential benefit of rupture prevention. Objective The aim of this study is to evaluate the clinical and anatomical results of endovascular treatment for UIAs at our institution, to benchmark our practice and potential areas for improvement, and enable transparent communication with patients by providing accurate, evidence-based information. Methods We reviewed all patients treated for an UIA between January 2017 and July 2022. Patients were grouped according to treatment technique: simple or balloon-assisted coiling; stent-assisted coiling; or flow-diverter stent placement. Clinical outcomes included perioperative mortality, transient (<3 months), and permanent morbidity (>3 months). Anatomical results were graded with the Raymond-Roy or the O’Kelly-Marotta scales. Retreatment rates, length of hospitalization, readmissions, irradiation time, and total radiation dose were assessed. Results In total, 169 patients with 201 UIAs underwent 187 endovascular procedures without death, 1% permanent morbidity, 8% transient morbidity, and 4% retreatment. The treatment subgroups analysis shows an absence of permanent morbidity associated with flow-diverter stenting and stent-assisted coiling. Simple/balloon-assisted coiling suffered 2.6% permanent morbidity. Transient morbidity was observed in 9%, 9.5%, and 6.6% of flow-diverter stenting, stent-assisted coiling, and simple/balloon-assisted coiling, respectively. Conclusions In our hospital, about one in a hundred procedures caused lasting problems, while about one in 25 aneurysms needed a second treatment. These results reflect our case selection and multidisciplinary approach. Reporting them transparently helps patients understand what outcomes to expect at our hospital.

OBJECTIVE While endonasal transsphenoidal surgery (ETS) is the standard treatment for nonfunctioning pituitary adenomas (NFPAs), the postoperative recovery rates of secondary adrenal insufficiency and their predictive factors remain poorly understood. The authors investigated the relationship between the tumor resection rate and adrenal function recovery in patients with NFPAs. METHODS This retrospective study included 450 patients with NFPAs who underwent ETS between January 2013 and November 2023. The rates of preoperative hypopituitarism and postoperative recovery rates of secondary adrenal insufficiency and their associated factors were analyzed. Recovery was defined as normalization of serum cortisol levels without replacement therapy for at least 24 hours, accompanied by symptom resolution. The tumor resection rate was calculated as the percentage of the tumor volume resected. RESULTS The median follow-up period for the entire cohort was 52 months (range 1–131 months). A total of 246 (55%) patients had dysfunction in one or more pituitary axes. Fifty-three (47%) of 114 patients with preoperative adrenal insufficiency showed postoperative adrenal insufficiency recovery. The cumulative adrenal insufficiency recovery rates were 12% at 1 month, 19% at 3 months, 32% at 6 months, and 41% at 12 months. Among the 114 patients with preoperative adrenal insufficiency, the factors associated with postoperative adrenal insufficiency recovery were investigated. Patients with smaller tumor sizes of < 20 mm (log-rank test, p = 0.001) and those with tumor resection rates of more than 85% (log-rank test, p = 0.032) demonstrated better postoperative adrenal insufficiency improvement. Bivariate Cox proportional hazards analysis demonstrated that smaller tumor sizes (continuous, HR 0.97, 95% CI 0.93–0.98; p = 0.043) and higher tumor resection rates (HR 1.03, 95% CI 1.01–1.07; p = 0.001) were significantly associated with better postoperative adrenal insufficiency recovery. Multivariable analysis confirmed that only higher tumor resection rates were significantly associated with better postoperative adrenal insufficiency recovery (HR 1.03, 95% CI 1.01–1.06; p = 0.019). CONCLUSIONS Nearly half of the patients with preoperative adrenal insufficiency achieved recovery after ETS for NFPAs. The enhanced extent of tumor removal was an independent factor associated with better postoperative recovery, indicating that optimizing safe maximal resection procedures may be crucial in enhancing adrenal function.

Abstract Selective myectomy has gained popularity for treating facial synkinesis. We examined the combined effectiveness of depressor anguli oris (DAO), partial buccinator, and platysma myectomies. Retrospective case series. Pre- and postoperative botulinum toxin-A (BTX-A) treatments of selective myectomy patients were collected. Facial photographs were analyzed using Emotrics + . Facial Asymmetry Index (FAI) and electronic facial paralysis assessment (eFACE) scores were calculated. Twenty patients underwent myectomies. Improvements (mean ± standard error) were seen in several smile metrics, including FAI by 2.80 ± 0.68 mm, nasolabial fold angle by 4.78 ± 1.83 degrees, and smile angle by 4.43 ± 1.18 degrees (all p < 0.05). Postoperative FAI was 2.79 mm. Total BTX-A decreased by 10.85 ± 4.48 units (p = 0.03). eFACE revealed improved oral commissure movement and platysmal synkinesis (p < 0.05 for both). Combined myectomies of the DAO, partial buccinator, and platysma clinically and statistically improve smile in facial synkinesis.

This practice recommendation serves as an update to the 2023 AASLD Practice Guidance on the clinical assessment and management of nonalcoholic fatty liver disease (NAFLD), now known as metabolic dysfunction–associated steatotic liver disease (MASLD), and provides implementable guidance on patient selection for treatment, consideration of comorbidities, and monitoring of treatment safety and efficacy of semaglutide. FDA-indication and Practice Recommendation: The Wegovy formulation, whose main ingredient is semaglutide, received accelerated FDA approval in August 2025 for treating MASH with moderate-to-advanced fibrosis (consistent with stages F2–F3 fibrosis), based on interim results of the phase 3 ESSENCE trial where 72 weeks of 2.4 mg/week subcutaneous injection resulted in achievement of both primary histologic endpoints: (1) resolution of MASH without worsening of fibrosis (62.9% vs. 34.3% placebo, p <0.001) and (2) ≥1 stage reduction in liver fibrosis without worsening of MASH (36.8% vs. 22.4% placebo, p <0.001); final approval awaits long-term outcomes. Patient Selection: Candidates should have MASH with stage 2–3 fibrosis, identified using non-invasive tests (NITs) such as VCTE (8–15 kPa), MRE (3.1–4.4 kPa), or ELF (9.2–10.5), rather than liver biopsy, which is impractical and unnecessary for most patients. In those with VCTE (15–20 kPa), MRE (4.4–5 kPa), or ELF (10.5–11.3), an individualized decision to treat should be based on exclusion of cirrhosis with another confirmatory NIT, or cross-sectional imaging excluding nodular-appearing liver contour and signs of portal hypertension, or a platelet count of <150,000/mm 3 . While semaglutide is not approved to treat patients with MASH cirrhosis (VCTE >20 kPa, MRE>5.0 kPa, ELF>11.3, and/or evidence of portal hypertension), those with compensated cirrhosis who are receiving semaglutide for another FDA-approved indication should be monitored carefully. Monitoring and Safety: Semaglutide showed a favorable hepatic safety profile in the ESSENCE trial, with no discontinuations due to liver enzyme elevations. Routine hepatic panels are recommended only as clinically indicated. The most common adverse events were gastrointestinal (nausea, diarrhea, constipation, vomiting), generally mild and transient; patient education and dose titration help improve tolerance. Clinicians should monitor for rare but serious risks, including acute kidney injury (from dehydration), symptomatic gallbladder disease, pancreatitis, thyroid C-cell tumors, retinopathy progression, and lean mass loss. Treatment Response and Concomitant Therapy: Lifestyle modification remains the cornerstone of MASLD/MASH management alongside semaglutide. Combination use of resmetirom with semaglutide 2.4mg/week has not been studied. While no NITs reliably predict histologic response at the individual patient level, reductions from baseline to 72 weeks of treatment suggest significant improvement in MASH resolution (ALT ≥17 U/L or ≥20%) and fibrosis improvement (VCTE LSM ≥30%; MRE LSM ≥20%; ELF ≥0.5). Non-response may be suspected if ALT or NITs worsen. The benefit is uncertain if a suboptimal response occurs, and may require an individualized approach and further follow-up.

Background. Delayed graft function (DGF) in deceased-donor kidney transplantation increases morbidity, prolongs hospitalization, and increases healthcare costs. Hypothermic machine perfusion (HMP) has emerged as a promising strategy to reduce DGF; however, large-scale real-world data remain limited. Methods. We performed a retrospective cohort analysis using the Scientific Registry of Transplant Recipients (2014–2024), including adult dialysis-dependent recipients of deceased-donor kidneys preserved using either static cold storage (SCS) or HMP. The primary outcome was DGF, defined as dialysis requirement within 7 d posttransplant. A matched-pairs analysis was conducted using kidneys from the same donor. Results. The overall cohort included 59 859 recipients (46.8% SCS, 53.2% HMP), with 2208 matched pairs identified. In the overall cohort, HMP grafts had longer cold ischemia times and a higher kidney donor risk index. They were more frequently obtained from older and donation after circulatory death donors. Although the overall DGF incidence was higher with HMP (34.4% versus 30.9%, P < 0.001), matched-pairs analysis revealed significantly lower DGF rates with HMP (29.8% versus 36.1%, P < 0.001). Adjusted analyses identified HMP as protective against DGF (overall cohort odds ratio, 0.71; 95% confidence interval, 0.66-0.78; paired cohort OR, 0.68; 95% CI, 0.50-0.93). Additional modifiable risk factors include prolonged cold ischemia time, higher recipient body mass index, and longer dialysis duration. Conclusions. This real-world study demonstrates that HMP is associated with a significant reduction in DGF risk in kidney transplantation compared with SCS, supporting its broader implementation and targeted management of modifiable risk factors.
