Long-Term Seizure Outcome With or Without Vagal Nerve Stimulation Therapy.

To compare long-term seizure control in patients with long-term VNS (vagal nerve stimulator) stimulation (VNS-on) with those who discontinued VNS after >3 years (VNS-off). Patients with refractory epilepsy with VNS therapy for >3 years (and follow-up for >2 years after VNS discontinuation for VNS-off patients) were included. Patients with brain surgery <3 years after VNS were excluded. We compared the percentage of patients with ≥50% seizure reduction (50% responder rate) and change in seizure frequency within and between groups in follow-up. Thirty-three VNS-on and 16 VNS-off patients were evaluated. VNS-on patients underwent stimulation for 9.7 years (mean). VNS-off patients had VNS treatment for 6.5 years (mean), discontinued treatment, then had additional 8.0 years (mean) follow-up. 50% responder rates were similar between groups (VNS-on: 54.5% vs VNS-off at last-on: 37.5%, p = 0.26; vs VNS-off at the last follow-up: 62.5%, p = 0.60). VNS-on patients had a significant reduction in seizure frequency at the last follow-up compared with baseline (median [Mdn] = -4.5 seizures/month, interquartile range [IQR] = 14.0, 56% reduction, p = 0.013). VNS-off patients also showed significant seizure reduction while still continuing VNS therapy (Mdn = -1.0 seizures/month, IQR = 13.0, 35% reduction, p = 0.020) and, after discontinuing therapy, at the last follow-up compared with baseline (Mdn = -3.2, IQR = 11.0, 52% reduction, p = 0.020). The 2 groups were comparable in seizure frequency change both at the last-on visit (absolute change, p = 0.62; relative change, p = 0.50) at the last follow-up (absolute change, p = 0.67; relative change, p = 0.76). Patients who discontinued VNS therapy and those who continued therapy had similar response during active treatment and similar long-term outcomes, suggesting that factors such as the natural disease course and/or medication treatment strongly affect long-term outcomes.

Education and employment outcomes in pediatric chronic kidney disease.

As outcomes and survival for children with chronic kidney disease (CKD) have improved over the last 30years, there is an emerging need to characterize and understand later educational and employment outcomes across the spectrum of pediatric CKD severity-ranging from mild CKD to requirement for dialysis and kidney transplantation. Although large-scale research on the topic of long-term educational and employment outcomes in the pediatric CKD population is relatively scarce, the existing literature does support that children across the spectrum of CKD severity are at risk for education-related difficulties including chronic school absenteeism. These education-related difficulties are compounded by well-described neurocognitive deficits-particularly in the domain of executive functioning-that may potentially perpetuate the risk for academic underachievement. This is particularly concerning given that data from the general pediatric population suggest that childhood academic underachievement is associated with higher likelihood of un-/underemployment in adulthood. This review highlights what is known about educational and employment outcomes among persons with a history of childhood CKD, as well as suggestions for interventions to improve educational outcomes for this population.

Impact of a novel oxidized regenerated cellulose application method on postoperative outcomes and lung function recovery in lung volume reduction surgery for emphysema

BackgroundOne of the significant complications associated with Lung volume reduction surgery (LVRS), which is a critical intervention for patients with advanced emphysema, is the development of postoperative air leaks. We have found that oxidized regenerated cellulose (ORC) can be used in LVRS to minimize postoperative air leaks and enhance recovery in our clinical work. This study evaluates the efficacy of a novel ORC application method in improving lung function and reducing complications in patients undergoing LVRS for emphysema. MethodsA comparative analysis was conducted on 83 patients who underwent LVRS, divided into two groups: 41 received ORC (ORC group), and 42 did not (No-ORC group). Lung function parameters, including Forced Expiratory Volume in One Second (FEV1), Forced Vital Capacity (FVC), FEV1/FVC ratio, and FEV1% predicted, were measured preoperatively and at 3, 6, and 12 months postoperatively. Postoperative outcomes, such as the duration of chest tube placement, hospital stay, and the incidence of air leaks, were also compared. ResultsPreoperative characteristics, including age, sex, smoking history, Body Mass Index (BMI), and baseline lung function, were similar between the two groups. Postoperatively, both groups showed improvements in lung function. By 12 months, lung function parameters between the groups were comparable. The ORC group had a shorter duration of chest tube placement (mean 4.41 days vs. 6.76 days, P < 0.01) and hospital stay (mean 6.78 days vs. 9.12 days, P < 0.01). Additionally, the incidence of postoperative air leaks was lower in the ORC group compared to the No-ORC group (P < 0.01). ConclusionsThe novel application method of ORC in LVRS is associated with enhanced early postoperative recovery, reflected in shorter chest tube duration, reduced hospital stays, and a lower incidence of postoperative air leaks. And, long-term lung function outcomes between ORC and No-ORC groups are similar.

Lumbocaval Shunt for Idiopathic Intracranial Hypertension: A Technical Report and Case Series

BACKGROUND AND OBJECTIVES: Neurosurgical management of idiopathic intracranial hypertension (IIH) can be challenging given high rates of revision associated with cerebrospinal fluid shunting. In this study, we present a technical report and early outcomes for lumbocaval shunt (LCS) placement in difficult-to-manage cases. METHODS: A literature search was performed for previous reports of LCS or lumboatrial shunt. Electronic medical records of patients who underwent placement of LCS for the treatment of IIH at a single institution were reviewed. Based on early experience and outcomes, our modified technique for LCS is described. RESULTS: Six patients (4 females, median age 36 years [IQR 31-43]) underwent placement of LCS between October 2023 and April 2024. LCS was completed in all cases without intraoperative complications. The median operative time was 88.5 minutes [IQR 79.5-158.8]. One patient developed low-pressure headaches that resolved after the addition of a shunt-assist device. Five of 6 patients reported improved headache at the last follow-up visit, with 4 of 5 patients reporting that their high-pressure headaches completely resolved (median time to the last follow-up of one month [IQR 1-2 months]). During the study period, one shunt revision was performed because of migration of the lumbar shunt into a suprafascial pocket. This led to modification of the surgical technique, specifically the inclusion of anchoring dips. CONCLUSION: LCS may represent an alternative shunting technique in difficult-to-manage patients with IIH. Further assessment of long-term outcomes is needed.

Outcomes of Management of Progressive Radiosurgery-Treated Brain Metastasis With Resection Followed by Pathology-Informed Management: A Retrospective Study

BACKGROUND AND OBJECTIVES: In patients treated with stereotactic radiosurgery (SRS) for brain metastases, follow-up imaging demonstrating progression may result from treatment effect/radionecrosis (RN) or tumor progression. We report long-term outcomes for a cohort of patients who demonstrated radiological progression on serial imaging after initial radiation and who underwent resection, at which point histology informed further management. METHODS: A retrospective chart review identified 76 patients with an associated 82 brain lesions between 2009 and 2022, that were initially treated with SRS, and then demonstrated suspicious imaging developing through at least 2 scan time points with either pathologic confirmation of tumor or RN. RESULTS: Of the 82 lesions, 55 lesions (67.1%) were found to be tumor and were treated with repeat radiation and 27 (32.9%) were found to have pathologically confirmed RN and conservatively managed. 14/27 lesions ultimately found to be radionecrotic required steroids preoperatively due to neurological symptoms. None of these lesions required further intervention with median postsurgery follow-up of 24.4 months (range 1-104 months). There were 55 instances (in 51 patients) of confirmed recurrent/progressive tumor who we treated with repeat aggressive radiation with either Cs-131 brachytherapy (12 [21.8%]) or SRS (43 [78.2%]). Among patients treated with reirradiation, the median follow-up to local failure was 15.2 months (95% CI 7.3-26.6 months). The 2-year local control rate was 79.5% (95% CI 68.3%-92.5%). CONCLUSION: These results support resection of radiosurgery-treated lesions with progression continuing through serial imaging, and this pathology-informed management results in excellent control of both RN and tumor progression after radiosurgery.

Best Available Outcomes Evidence Informing Standard of Care

Summary: Although nonoperative management is the mainstay for rib fracture treatment, surgical stabilization of rib fractures is becoming more common. Recently, the number of high-quality studies on management of rib fractures has also increased. The primary purpose of this review is to analyze the currently available prospective randomized studies on the management of rib fractures. In addition, we will summarize both short-term and long-term outcomes of patients with rib fractures.

Endovascular treatment for brain arteriovenous malformations via the anterior choroidal artery for casting Onyx-18.

Background: Few studies have investigated the safety of endovascular treatment (EVT) for brain arteriovenous malformations (BAVMs) via the anterior choroidal artery (AchA); therefore, this topic is worth studying further. Materials and methods: This was a retrospective study of 18 consecutive patients with BAVMs that were treated via the AchA with Onyx casting. Clinical and angiographic data were collected from the patients and analyzed. Results: The ages of the 18 patients ranged from 13 to 67years (mean 39.2 ± 14.7years), and eight patients were male (44.4%, 8/18). All patients had intracranial hemorrhages, including 2 with previous hemorrhages. All 18 BAVMs were mainly fed by the AchA and were treated via the AchA as the route for casting Onyx-18. Of the 13 single-trunk AchAs, after EVT, all proximal segments were preserved. For the 5 double-trunk AchAs, EVT was performed via the lower trunk; the proximal segments of the lower trunk were occluded for 2 of these AchAs. Among the 18 BAVMs, 16 niduses were embolized to different degrees, as were twelve associated aneurysms. Five (27.8%, 5/18) of the 18 patients experienced complications, and appropriate management was provided. During long-term follow-up, 14 (77.8%, 14/18) patients achieved good outcomes. Conclusion: EVT for BAVMs via the AchA has significant risks, but overall, good long-term outcomes were achieved in approximal 80% of the patients. This study highlights the potential of this technique for embolizing BAVMs via the AchA.

Vaccination in hemophilic children: Challenges, innovations, and future directions

Introduction: Hemophilia, an inherited disorder primarily affecting blood clotting due to deficiencies in clotting factors VIII or IX, presents complex challenges for vaccination. Children with hemophilia require vaccinations to prevent infections that may exacerbate their bleeding disorder. However, traditional intramuscular vaccination poses bleeding risks, necessitating specialized administration methods and careful post-vaccination care. Purpose: This study examines the efficacy and safety of vaccination in pediatric hemophilia patients, emphasizing the importance of individualized protocols to manage bleeding risks effectively. It explores recent advancements, including needle-free technologies, the potential of gene therapy, and mRNA vaccines. Materials and Methods: The study synthesizes current guidelines from global health organizations, hemophilia management protocols, and clinical studies on vaccine safety in hemophilia. It highlights techniques such as subcutaneous administration, clotting factor prophylaxis, and the use of fine-gauge needles to minimize bleeding complications. Results: Findings indicate that with appropriate management, hemophilic children achieve adequate immune responses to vaccines, with reduced bleeding risks. Emerging technologies, such as microneedle patches, jet injectors, and gene therapy, offer promising safer vaccination alternatives. Additionally, mRNA vaccines demonstrate strong immunogenicity without the need for live-virus vectors, reducing complication risks. Conclusions: Vaccination, when adapted to hemophilia-specific needs, remains essential for infection prevention in this vulnerable population. Newer vaccine technologies and individualized care protocols enhance safety and efficacy, contributing to improved quality of life and long-term health outcomes for hemophilic children.

Prevalence and Clinical Implications of Hemosiderin Deposits in Recent Small Subcortical Infarcts.

A quarter of ischemic strokes are of lacunar clinical subtype and have an underlying recent small subcortical infarct (RSSI), but their long-term outcomes remain poorly characterized. Hemosiderin deposits (HDs) have been noted in RSSIs at chronic stages and might mimic primary hemorrhage. We characterized HDs' morphology, frequency, and clinical relevance. Participants with RSSIs were identified from a prospective longitudinal study and evaluated on 3T MRI including susceptibility-weighted imaging (SWI) from stroke diagnosis to 12 months. We categorized HDs in RSSIs on SWI at all available time points into 4 types (spots, smudge, rim, cluster) and assessed their associations with demographic factors, stroke-related factors, and image markers with adjusted logistic regression. HDs were observed in 43 (55.0%) of 108 participants within 3 months and 83 (76.9%) of 108 within 12 months after stroke onset. The mean time to first detection of HDs was 87 (interquartile range 53-164) days. A "rim" pattern (similar to late appearance of primary hemorrhage) occurred in at least 26.5% of RSSIs at all follow-up time points, mainly those located in the lentiform/internal capsule (50.0%) or thalamus (36.4%). Infarct volume (odds ratio [OR] 1.003, 95% CI 1.001-1.006; p = 0.004) and the total small vessel disease (SVD) score at baseline (OR 2.50, 95% CI 1.28-4.86, p = 0.007) independently predicted HDs at 12 months. HDs were positively associated with more lacunes (OR 1.60, 95% CI 1.13-2.26, p < 0.01), but not the Fazekas score, number of microbleeds, basal ganglia mineral deposit score, or clinical outcomes. HDs occur commonly in RSSIs and may be associated with infarct volume and SVD score. Hemosiderin "rim" is common in RSSIs, urging caution to avoid mistaking ischemic RSSI for primary hemorrhage in subacute and chronic stages.

Long-term Outcomes of Surgical Treatment for Pancreatic Neuroendocrine Neoplasm with Synchronous Hepatic Metastasis: A Multicenter Retrospective Cohort Study

Abstract Objectives: To evaluate surgical impact on the overall survival (OS) of pancreatic neuroendocrine neoplasm (pNEN) with synchronous hepatic metastases (sHM). Methods: A total of 163 pNEN-sHM patients were recruited from 3 institutions in China, who were categorized into 3 groups: no resection (NR), resection of the primary lesion (PR) and resection of both primary and hepatic lesions (PHR). Cox regression was employed to evaluate surgical impact on the OS. Results: In the overall cohort analysis, PHR demonstrated a significant protective effect on OS (HR 0.302, 95% CI: 0.127–0.721, p = 0.007). Nevertheless, subgroup analysis revealed PHR conferred a survival advantage in patients with pancreatic neuroendocrine tumor (pNET) located on the pancreatic body/tail (bt-pNET-sHM) (HR 0.287, 95% CI: 0.087–0.946, p = 0.040), whereas surgical treatment did not significantly impact survival in the subgroups of pancreatic neuroendocrine carcinoma (pNEC)-sHM or pancreatic head/neck pNET-sHM (hn-pNET-sHM). Conclusions: In this study, the survival benefit of surgery was only observed in the bt-pNET-sHM subgroup. Considering the multifactorial nature of decision-making, surgical intervention for pNEN-sHM management should be approached with a careful and comprehensive assessment, to prevent excessive surgery strategies.

The protocol for BROWSE-P (breast reconstruction outcomes with Strattice™ or Artia™ – pre-pectoral): a cohort study to assess long-term outcomes of immediate pre-pectoral implant based breast reconstruction with Strattice™ or Artia™

Introduction: Techniques in implant-based breast reconstruction (IBBR) have evolved over the last 15 years due to the introduction of mesh or acellular dermal matrices (ADMs). Traditionally, total submuscular coverage progressed to upper pole muscle cover with lower pole ADM and now total or anterior ADM cover in the pre-pectoral plane. Data is scarce to support the pre-pectoral technique but, it is suggested to result in less postoperative pain, more natural cosmesis and avoidance of animation deformity. The BROWSE study concluded that subpectoral with Strattice™ IBBR resulted in better cosmesis and lower rates of capsular contracture when compared to the total submuscular technique. The BROWSE-P study aims to assess the safety profile of Artia™ a porcine derived ADM and review the long-term outcomes of pre-pectoral IBBR with Strattice™ and Artia™. Methods and analysis: BROWSE-P is a single center cohort study. Consecutive patients who have undergone immediate pre-pectoral IBBR with Strattice™ or Artia™ from January 2017 to December 2022 will be included. Demographic, operative, oncology, complication, and further surgery data with be collected to assess the rate of revision surgery and safety profile of Artia™. Those who have their implant reconstruction in situ will be invited for clinical assessment to assess for capsular contracture. Participants will also be asked to complete a BREAST-Q post-reconstruction module, to assess patient satisfaction and quality of life, and have medical photographs taken for an assessment of aesthetic outcome by a blinded panel using the 10-point Visser scale. We aim to collect data on 500 reconstructions and complete clinical assessment, patient reported outcomes and aesthetic assessment for 250 patients.

In vitro fertilization and long-term child health and development: nationwide birth cohort study in Japan

AbstractThe aim of this study is to compare long-term health outcomes between IVF-conceived children and non-IVF-conceived children in Japan, in the context of strong recommendation for single embryo transfer. Using data from a nationwide birth cohort linked with perinatal database, this study analyzed 2140 children born in Japan in May 2010. It compared child health and development outcomes up to 9 years of age between IVF-conceived and non-IVF-conceived children (binary exposure). A Poisson regression with robust variance to estimate the risk ratios for the association between IVF and various long-term child health and developmental outcomes. After adjusting for confounding factors, no significant differences were observed between IVF-conceived and naturally conceived children for most outcomes, including hospitalization, obesity, and developmental milestones. IVF-conceived children showed a slightly lower risk of attention problems at 8 years (adjusted Risk Ratio [aRR]: 0.73, 95% CI: 0.53–1.00). In subgroup analyses, IVF-conceived term children and singletons demonstrated reduced risk of cognitive delays at 5.5 years (aRR: 0.31, 95% CI: 0.10–0.96 and aRR: 0.37, 95% CI: 0.14–0.98, respectively).Conclusion: In this Japanese cohort, IVF conception was not associated with adverse long-term health or developmental outcomes. These findings provide reassurance about the safety of IVF, particularly in the context of single embryo transfer policies. Further research is needed to explore specific IVF protocols and subgroups. What is known:• Long-term health and developmental outcomes of IVF-conceived children remain inconsistent across studies and populations, despite the widespread use of this technology. What is new:• A nationwide population-based cohort study in Japan did not show adverse effects of IVF on long-term child health and development through age 9.• These findings provide reassurance about the safety of IVF, while indicating the need for careful monitoring in specific subgroups such as preterm and multiple births.

Long-term outcomes following posterior fossa decompression in pediatric patients with Chiari malformation type 1, a population-based cohort study

Abstract Objective Posterior fossa decompression for Chiari malformation type I (Chiari 1) is effective and associated with a low risk of complication. However, up to 20% of patients may experience continued deficits or recurring symptoms after surgical intervention. For pediatric patients, there are no established tools to predict outcomes, and the risk factors for unfavorable postoperative outcomes are poorly understood. Hence, our aim was to investigate baseline data and early postoperative predictors of poor outcomes as determined by the Chicago Chiari outcome scale (CCOS). Methods All pediatric patients (&lt; 18 years) receiving a posterior fossa decompression for Chiari 1 between the years of 2005 and 2020 at the study center were eligible for inclusion. Patients with congenital anomalies were excluded. Results Seventy-one pediatric patients with a median age of 9 years were included. Most patients (58%) were females. Chiari 1 was associated with syringomyelia (51%), scoliosis (37%), and hydrocephalus (7%). Perioperative complications occurred in 13 patients (18%) of which two required additional procedures under general anesthesia. On multivariable proportional odds logistic regression, motor deficits (OR: 0.09; CI95%: [0.01–0.62]; p = 0.015), and surgical complications (OR: 0.16; CI95%: [0.41–0.66]; p = 0.011) were significant predictors of worse outcomes. The presence of syringomyelia was identified as a predictor of better outcomes (OR: 4.42 CI95% [1.02–19.35]; p = 0.048). A persistent hydrocephalus during the early postoperative period after posterior fossa decompression was a strong predictor of worse long-term CCOS (OR: 0.026; CI95%: [0.002–0.328]; p = 0.005). Conclusion Results from this study indicate that the existence of motor deficits and syringomyelia prior to surgery, and surgical complications and persistent hydrocephalus despite posterior fossa decompression, were useful predictors of long-term outcome.

Epigenetic Alterations in Post-Traumatic Stress Disorder: Comprehensive Review of Molecular Markers

Background: Post-traumatic stress disorder (PTSD) can occur after a traumatic event. PTSD is characterized by nightmares, flashbacks and avoidance of stressors. It currently affects 2–8% of the population, with military personnel particularly susceptible. Studies show that environmental stressors can induce various epigenetic changes that shape the PTSD phenotype. Despite the significant impact of epigenetic factors on PTSD symptoms and susceptibility, they have not been widely discussed in the literature. This review focuses on describing epigenetic mechanisms in PTSD, especially DNA methylation, chromatin regulation, and noncoding RNA. Summary: The article includes relevant studies published from 2013 to 2023, excluding non-English-language studies or studies with insufficient data. This review investigated gene methylation changes in association with PTSD, including those related to the hypothalamic-pituitary-adrenal axis, brain-derived neurotrophic factor, neurotransmitters, and immune system functioning, as well as the role of histones and regulatory noncoding RNAs. Key Messages: Epigenetic alterations play a crucial role in shaping PTSD susceptibility, symptomatology, and long-term outcomes, highlighting their potential as important markers and therapeutic targets. Understanding these alterations can aid in developing clinical strategies to better predict, prevent, and treat PTSD. However, further large-scale longitudinal studies are needed to establish the temporal relationship between epigenetic changes and the onset of PTSD, as well as to classify other potential epigenetic mechanisms.

Meta-analysis of longitudinal comparison of transcatheter versus surgical aortic valve replacement in patients at low to intermediate surgical risk

Background: Surgical aortic valve replacement (SAVR) is the commonly used approach for aortic valve replacement (AVR) in patients with aortic stenosis at low or intermediate surgical risk. However, transcatheter aortic valve replacement (TAVR) has emerged as an alternative to SAVR for AVR. This meta-analysis aims to assess the comparative efficacy and safety of TAVR versus SAVR in low-to-intermediate surgical risk patients by analyzing temporal trends in the outcomes of TAVR and SAVR at various follow-up intervals, providing a more detailed understanding. Methods: A thorough literature search was performed across PubMed/MEDLINE, Embase, and the Cochrane Library from their inception up to May 2024 to identify eligible randomized controlled trials (RCTs). Clinical outcomes were evaluated using a random-effects model to pool risk ratios (RRs) with 95% confidence intervals (CIs). Results: A total of 17 studies reporting data at different follow-ups for 9 trials were included (n=9,092). No statistically significant difference was observed between TAVR and SAVR for reducing all-cause death at 30 days, 1 year, and 2 years but significantly increased risk with TAVR at 5 years or longer follow-up (RR=1.13, 95% CI: 1.03 to 1.23). However, TAVR was associated with a significantly decreased risk for cardiac death at 1-year follow-up (RR=0.79, 95% CI: 0.64 to 0.96) and comparable risk for cardiac death at 30 days, 2 years, and 5 years or longer follow-up when compared with SAVR. No statistically significant difference was observed between TAVR and SAVR for reducing the risk of myocardial infarction (MI) at 30 days, 1 year, 2 years, and 5 years or longer follow-up. TAVR was associated with a significantly lower risk of major bleeding events at 30 days (RR=0.38, 95% CI: 0.21 to 0.67); lower risk of acute kidney injury (AKI) at 30 days (RR=0.38, 95% CI: 0.26 to 0.54) and 1 year (RR=0.58, 95% CI: 0.41 to 0.82) and lower risk of new onset or worsening atrial fibrillation (AF) at 30 days (RR=0.25, 95% CI: 0.18 to 0.34), 1 year (RR=0.26, 95% CI: 0.16 to 0.41) and 2 years (RR=0.32, 95% CI: 0.20 to 0.49) when compared with SAVR. However, TAVR was associated with a significantly increased risk of permanent pacemaker implantation (PPI) at 30 days (RR: 2.62, 95% CI: 1.40 to 4.91), at 1 year (RR: 2.19, 95% CI: 1.24 to 3.87), at 2 years (RR: 2.74, 95% CI: 1.31 to 5.71), and beyond 5 years (RR: 1.95, 95% CI: 1.20 to 3.15). TAVR was also associated with a significantly increased risk of prosthetic valve thrombosis at 2 years (RR=2.70, 95% CI: 1.08 to 6.71), though no significant association was observed at 30 days, 1 year, or 5 years. Similarly, no significant differences were observed in aortic-valve reintervention rates at 30 days, 2 years, or 5 years, but TAVR showed a significantly increased risk at 1 year (RR=1.98, 95% CI: 1.21 to 3.24). TAVR was associated with a significantly increased risk of major vascular complications at 30 days (RR=2.37, 95% CI: 1.38 to 4.04) and a significantly increased risk of TIA at 2 years (RR: 1.43, 95% CI: 1.02 to 2.00, I2=0%). The risk of hospitalizations was comparable between the groups. Conclusion: TAVR and SAVR demonstrated comparable rates of all-cause death up to 2 years of follow-up. However, at 5 years or longer follow-up, TAVR was associated with a higher risk of all-cause death. While TAVR showed certain procedural advantages, such as a lower risk of major bleeding, AKI, and new-onset or worsening AF, the choice between TAVR and SAVR in patients with low or intermediate surgical risk should consider long-term outcomes, with SAVR potentially being more favorable due to better survival observed on longer follow-up durations.

Short- and long-term outcomes of adrenalectomy for primary aldosteronism in a single UK center: rear-mirror view

Abstract Purpose Primary aldosteronism (PA), which is the commonest cause of secondary hypertension, can be cured by unilateral adrenalectomy. We report the short-and long-term outcomes after adrenalectomy performed at a single UK center over a period of 24 years. Methods Retrospective analysis of biochemical (potassium, aldosterone, renin, and ARR) radiological (CT/MRI, AVS, and nuclear scans), and clinical (surgical complications, blood pressure, and number of antihypertensive medications) short-and long-terms outcomes in patients who underwent adrenalectomy for PA between 1998 and 2021. Standardized PASO and Clavien-Dindo criteria to assess biochemical, clinical, and surgical outcomes were used. Results A total of 82 patients were treated via adrenalectomy for PA over a 24-year period. Short-term follow-up data (within 3 months after surgery) was available for all 82 patients (M45, F37, mean age 51.7 years): 24 of them were followed up for at least 60 months (range 60 to 72 months) and 77 (93.9%) patients had laparoscopic surgery (one conversion). Seven patients had postoperative complications classified as Clavien-Dindo II (4), IIIa(1) and IVa(2). Median LOS was 2.5 days (1–12). Complete and partial clinical success was achieved in 29 and 58.3% and 41.7 and 45.8% of patients in the short and the long term, respectively. Clinical benefit was observed in 88% of patients. Complete biochemical success was achieved in 95.8% of patients in the short and the long term. Conclusion Unilateral adrenalectomy in patients with PA showed clinical benefit in 88% and achieved biochemical cure in almost all of them. Our data suggest that these benefits persisted for at least 5 years.

Adipose tissue retains an epigenetic memory of obesity after weight loss

AbstractReducing body weight to improve metabolic health and related comorbidities is a primary goal in treating obesity1,2. However, maintaining weight loss is a considerable challenge, especially as the body seems to retain an obesogenic memory that defends against body weight changes3,4. Overcoming this barrier for long-term treatment success is difficult because the molecular mechanisms underpinning this phenomenon remain largely unknown. Here, by using single-nucleus RNA sequencing, we show that both human and mouse adipose tissues retain cellular transcriptional changes after appreciable weight loss. Furthermore, we find persistent obesity-induced alterations in the epigenome of mouse adipocytes that negatively affect their function and response to metabolic stimuli. Mice carrying this obesogenic memory show accelerated rebound weight gain, and the epigenetic memory can explain future transcriptional deregulation in adipocytes in response to further high-fat diet feeding. In summary, our findings indicate the existence of an obesogenic memory, largely on the basis of stable epigenetic changes, in mouse adipocytes and probably other cell types. These changes seem to prime cells for pathological responses in an obesogenic environment, contributing to the problematic ‘yo-yo’ effect often seen with dieting. Targeting these changes in the future could improve long-term weight management and health outcomes.
