Evaluating laser interstitial thermal therapy for newly diagnosed, deep-seated, large-volume glioblastoma: survival and outcome analysis.

Laser interstitial thermal therapy (LITT) has emerged as an alternative for treating glioblastoma (GBM) in patients deemed unsuitable for resection due to deep-seated or eloquent location, age, or comorbidities. However, its safety and efficacy in large-volume, deep-seated, newly diagnosed GBM (nGBM) tumors remain insufficiently studied. Therefore, the authors aimed to assess the outcomes of LITT in the treatment of deep-seated, large-volume nGBM. A retrospective analysis of patients with nGBM who underwent LITT between February 2013 and August 2023 was conducted. Patients with deep-seated tumor volume ≥ 10 cm3 treated with LITT were compared to patients with deep-seated tumor volume < 10 cm3. Demographic, perioperative, and follow-up data were collected and compared among both groups. Kaplan-Meier survival analysis and Cox proportional hazards regression were performed to evaluate the impact of various clinical and treatment-related factors on patient survival. A total of 33 patients in the study group (mean ± SD age 65.7 ± 10.2 years, 58% male) with mean tumor volume 36.0 ± 21.6 cm3 were compared to 23 controls (mean age 67.0 ± 12.5 years, 61% male) with mean tumor volume 5.2 ± 2.7 cm3. There were no significant differences in hospital length of stay (p = 0.494), temporary neurological deficits and edema within 30 days (p = 0.705 and p > 0.999, respectively), 30-day readmissions (p = 0.139), < 30-day complications (p = 0.918), complications between 30 days and 3 months (p = 0.903), and new motor and speech deficits within 3 months (p = 0.883 and p > 0.999, respectively) between the study and control groups. Kaplan-Meier analysis did not reveal any statistically significant difference in overall survival (OS) between groups (p = 0.227). Multivariate analysis indicated that tumor volume did not significantly affect the hazard ratio for individuals undergoing LITT (HR 1.16, 95% CI 0.83-3.29, p = 0.150). This pilot study suggests that LITT is safe for treating patients with large-volume, deep-seated nGBM compared to those with small-volume tumor. Although there appears to be improved OS in patients with smaller lesions with greater EOA, significance was not achieved in this cohort.

A retrospective nationwide comparison of laparoscopic vs open inguinal hernia repair in children

BackgroundUtilization of the laparoscopic approach for inguinal hernia repair has increased significantly over the past decade. The purpose of this study is to compare rates of second hernia operation and same side recurrence following open and laparoscopic inguinal hernia repair in a large national cohort. MethodsThis retrospective analysis utilized the Pediatric Health Information System database to identify children <18 years-old who underwent laparoscopic or open primary inguinal hernia repair from 2017-2021. Data were collected through 2022 to allow minimum one year follow-up. Second hernia operation rates, inclusive of same side recurrence and metachronous contralateral hernia, and same side recurrence rates were compared by multivariable mixed effects model controlling for confounders and institutional clustering. Misclassification rates were determined through data validation at four constituent institutions. Sensitivity analyses determined true outcome rates. ResultsWe identified 53,287 operations (15.6% laparoscopic). Rate of second hernia operation was greater following laparoscopic repair (2.9% vs 2.6%, p=0.04) with no difference on multivariable analysis (OR 1.14, 95% CI 0.98-1.32). Same side recurrence rate was greater following laparoscopic repair (1.5% vs 0.4%, p<0.001) which persisted on multivariable analysis (OR 3.72, 95% CI 2.90-4.78). Sensitivity analysis demonstrated true laparoscopic and open repair rates of 14.2% and 85.8%, respectively. True rates of second hernia operation and same side recurrence were identical to those determined by PHIS. ConclusionLaparoscopic inguinal hernia repair in children has more than three times the odds of same side hernia recurrence than open repair which is balanced by a reduced rate of second operation for metachronous hernia.

Impact of Frailty on COVID-19 Hospitalizations: Results from the California State Inpatient Database.

Frail patients are at greater risk of experiencing adverse clinical outcomes in any critical illness due to decreased physiologic reserves, greater susceptibility to the adverse effects of treatment, and greater needs for intensive care. In this study, we sought to assess the prevalence of frailty and associated adverse in-hospital outcomes among coronavirus disease 2019 (COVID-19) hospitalizations using the 2020 California State Inpatient Database (SID). For this study, we conducted a retrospective analysis of data from all COVID-19 hospital patients aged 18 years and older. We identified hospitalizations that were at high risk of frailty using the Hospital Frailty Risk Score. The primary outcome of our study was in-hospital mortality, and the secondary outcomes were prolonged length of stay, vasopressor use, mechanical ventilation, and intensive care unit admission. The prevalence of frailty was 44.3% among COVID-19 hospitalizations. Using propensity score matching analysis, we found that the odds of mortality (odds ratio [OR] 4.54, 95% confidence interval [CI] 4.28-4.82), prolonged length of stay (OR 2.81, 95% CI 2.70-2.90), vasopressor use (OR 8.65, 95% CI 7.45-10.03), mechanical ventilation (OR 6.90, 95% CI 6.47-7.35), and intensive care unit admission (OR 7.17, 95% CI 6.71-7.66) were significantly higher among the group of frail patients. Our findings show that frailty could be used for assessing and risk stratifying patients for improved hospital outcomes.

Real word outcomes of cabozantinib therapy in poorly differentiated thyroid carcinoma.

Poorly differentiated thyroid carcinomas (PDTCs) are rare and aggressive head and neck malignancies with a poor prognosis. Systemic treatment for incurable PDTC consists of multi-kinase inhibitors (MKIs) based on extrapolation from the experience with radioiodine refractory differentiated thyroid cancer (DTC). Cabozantinib is an approved second line MKI therapy for DTC, but there are limited data regarding safety and efficacy of cabozantinib for PDTC. We conducted a single institution, retrospective analysis of patients with PDTC who received cabozantinib in any line of therapy. Baseline demographics, disease characteristics, treatment history, toxicity, and clinical outcomes were abstracted from the electronic medical record. Median PFS and OS were primary endpoints and estimated using Kaplan-Meier methodology. Seven patients with PDTC who received cabozantinib, were included. 4/7 (57%) patients had a partial response to cabozantinib, while 2/7 (29%) had SD as their best response. Median time on treatment for cabozantinib was 10.53 months. Median PFS from start of cabozantinib was 12.9 months and median OS was 14.21 months. Most adverse events to treatment (5/6) were low grade. Two (29%) patients were alive at date of last follow up. Cabozantinib is an effective and reasonably well-tolerated treatment option for patients with PDTC. Prospective studies are needed to further investigate the role of cabozantinib in the treatment of PDTC, alone and in combination with other agents including checkpoint inhibitors.

Adhesive restorations in primary dentition: A retrospective analysis of survival rate and associated factors.

Several clinical and individual factors may play a role in the survival rate of dental restorations, such as characteristics related to the child's age and oral hygiene, and factors associated with the tooth, such as the type of material and number of surfaces to be restored. To analyse the survival rate of adhesive restorations on primary teeth and factors associated with restoration survival. The study included dental records of children aged 3-12 years having received adhesive restorations on primary teeth at a Brazilian dental school between 2009 and 2019. A Kaplan-Meier survival curve was used to plot survival rates using the log-rank test. A multivariate Cox regression model was run to identify individual and dental factors associated with restoration failure. The sample comprised 269 restored teeth in 111 children. Survival curves were similar for all materials (p = .20) and types of isolation (p = .05). The annual failure rate was 3.60% for glass ionomer cement, 1.23% for resin-modified glass ionomer cement and 0.40% for composite resin. The following variables were associated with more failures: Class II restoration compared with Class I (HR = 1.96; 95%CI: 1.28-2.99, p < .001), proportion of decayed teeth (HR = 11.89; 95%CI: 2.80-50.57, p < .001) and child's age (HR = 1.17; 95%CI: 1.06-1.29, p < .001). The different materials and types of isolation had similar survival rates. Children with more decayed teeth have an increased risk of restoration failure.

Minimally Invasive Tube Surgery (MITS)—A Novel Method in Glaucoma Drainage Device Implantation

Background/Objectives: We introduce a new surgical technique for inserting the eyePlate-300—a glaucoma drainage device (GDD). The flexibility of the eyePlate-300 allows for folding and insertion through a smaller conjunctival incision. The procedure is termed minimally invasive tube surgery (MITS). Methods: We performed a retrospective analysis of thirteen eyes to assess the efficacy of the MITS technique in a large London tertiary teaching eye hospital with 12 months follow-up. The primary outcome was complete success: defined as ‘IOP &gt; 5 mmHg, &lt;21 mmHg and off drops’. Secondary outcomes: best corrected visual acuity at 12 months, complications, a reduction in the number of drops and need for further pressure-lowering surgery. Results: Twelve eyes (92%) achieved a lower IOP. The mean pre-operative IOP was 35.69 mmHg (20–53 mmHg); post-operatively, it was reduced to 11.08 mmHg (5–20 mmHg) (p &lt; 0.001). The mean pre-operative drops were 3.462 (3–4), reducing to 0.85 (0–3) at 12 months (p &lt; 0.001). There was no change in the mean BCVA. No intraoperative complications were recorded, and no further IOP lowering surgeries were required. Conclusions: The MITS technique facilitates the implantation of a glaucoma drainage device through a smaller, less traumatic incision. Preliminary one-year data suggest that the procedure may be safe and effective.

Temporal patterns and individual characteristics of compulsory treatment orders for mental disorders in Scotland from 2007 to 2020

Background Compulsory mental health treatment has increased globally. In Scotland, compulsory treatment for &gt;28 days is permitted under hospital- and community-based compulsory treatment orders. Community-based compulsory treatment has not been shown to lead to improved outcomes, and scrutiny of their use is needed. Aims To describe the trend, duration and demographic characteristics of compulsory treatment orders in Scotland over a 14-year period. Method We conducted a retrospective analysis of order use in Scotland from 1 January 2007 to 31 December 2020, focusing on the (a) number and demographic characteristics of those treated, (b) duration, (c) extensions beyond the 6-month review point and (d) characteristics of new versus continued orders. Results The number of individuals on a community-based order increased by 118% (571 v. 1243) from 2007 to 2020, compared with a 16% increase (1316 v. 1532) for hospital-based orders. Of orders starting in 2007, 57.3% were extended, compared with 43.7% in 2020. The median duration was 6 months for first-time orders and 9 months for subsequent orders, which were longest for males (median 11 months); those of African, Caribbean or Black (median 11 months), Asian (median 11 months) and mixed ethnicity (median 10 months); and individuals from the most deprived communities (median 10 months). Conclusions There has been a marked rise of community-based compulsory treatment orders in Scotland. If existing trends continue, there will be more people receiving care under community-based orders than hospital-based orders, fundamentally changing the nature of involuntary treatment. Further work needs to explore associations between demographic and diagnostic characteristics on order duration.

Wilms’ Tumor – An Audit

ABSTRACT Background and Aims: Outcome analysis of patients with Wilms’ tumors (WT) is presented. Materials and Methods: A retrospective analysis of 23 children having WT managed by a single surgeon over 3 years (2021–2024) using the International Society of Paediatric Oncology Umbrella protocol was done. Results: The median age at presentation was 36 months; 32 months and 24 months for the unilateral WT (uWT) (n = 19) and bilateral WT (bWT) (n = 4), respectively. M: F ratio was 2.3: 1. WTs were localized in 19 (uWT-16; bWT-3) and metastatic in 4 (uWT-3; bWT-1) patients. Core-needle biopsy was done in 22 patients (26 renal units). Pre-therapy contrast-enhanced computed tomography volumetry (n = 20) showed a median tumor volume of 1023 ml (range: 47–2680 ml). Post-neoadjuvant chemotherapy (NACT) median tumor burden (n = 19) was 612 ml (range 59–3775 ml). Post-NACT, tumor volume decreased in 11/18 patients but increased in seven patients. NACT was avoided in one neonate. Nephroureterectomy (including one with excision of bladder cuff) and nephron-sparing surgery were done in 17 and 10 renal units including 3 with multifocal WT, respectively. Risk stratification was intermediate in 21 and High in 2. Overall staging in 19 uWT included Stage I-7, Stage II-5, Stage III-4, and Stage IV-3 (local staging-stage I in 1 and stage II in 2). Local staging in 8 renal units with bWT was Stage I in 7 and II in 1. One stage IV uWT had bilateral pulmonary metastatectomy. Adjuvant chemotherapy has been completed in 18 patients; two patients are still on adjuvant chemotherapy; flank radiation was administered in six patients. Three patients with synchronous bWT died; two due to acute kidney injury in the immediate postoperative period and one with metastatic disease who had abandoned adjuvant chemotherapy after the 1st cycle. Another patient died of a huge metachronous tumor in the contralateral kidney after a year of completion of therapy. One patient had successful multimodality treatment of local relapse with liver metastasis. 1-year overall and event-free survivals are 84% and 76%, respectively. Conclusions: Excellent short-term results for localized uWT from a center in a low-middle-income country are reported.

Frailty and Malnutrition as Predictors of Major Complications Following Posterior Thoracolumbar Fusion in Elderly Patients: A Retrospective Cohort Study

Background ContextThe number of elderly patients with degenerative spinal deformity (DSD) is increasing, and posterior thoracolumbar fusion surgery is an effective treatment option, but there are often postoperative major complications, which may hinder the benefit for elderly patients. Currently, there is no consensus on the best risk assessment technique for predicting major complications in elderly patients undergoing long-segment fusion surgery. PurposeThis study constructs a risk assessment model using the Modified 5-Item Frailty Index (mFI-5) and serum albumin and evaluates its predictive value. Study DesignThis is a retrospective analysis of a prospectively established database of DSD. Patient SampleConsecutive patients (aged 65 and older) who underwent open posterior thoracolumbar fusion surgery for DSD between April 2018 and December 2023 were included. Outcome MeasuresOutcome measures included postoperative major complications, length of hospital stay [LOS], readmission and reoperation within 30 days, discharge disposition, physiological function recovery. MethodsThe study reviewed consecutive patients who underwent open posterior thoracolumbar fusion surgery for DSD. Patients were divided into three groups based on the presence or absence of frailty or frailty combined with malnutrition. Spearman ρ analysis was used to assess the correlation between mFI-5 and serum albumin levels. Univariate analyses and multivariate logistic regression were conducted to explore the relationship between frailty and malnutrition defined by mFI-5 and serum albumin and major postoperative complications. Finally, the Receiver Operating Characteristic (ROC) curve was used to evaluate the predictive value of this model for major complications. ResultsCompared to the Normal group (n = 59), both the Frailty group (n = 121) and the Frailty and Malnutrition group (n = 50) had higher rates of major complications (21.5% vs. 8.5%, p = .035; 28% vs. 8.5%, p = .002). Multivariate logistic regression showed that frailty and malnutrition status, higher ASA score, and more bleeding were independent predictors of major postoperative complications. The ROC curve demonstrated that frailty combined with malnutrition defined by mFI-5 and serum albumin had a larger area under the curve compared to mFI-5 or serum albumin alone (AUC: 0.676; 95% CI: 1.101-14.129; p < .001). ConclusionsCompared to considering frailty or malnutrition alone, the combined assessment of frailty and malnutrition using mFI-5 and serum albumin is valuable in predicting major complications in elderly patients undergoing posterior thoracolumbar fusion surgery.

Utilization and cost of non-insulin glucose-lowering drugs in Australia from 2013 to 2023.

To investigate the utilization and costs of non-insulin glucose-lowering drugs (GLDs) in Australia from 2013 to 2023. We conducted a retrospective analysis of the Australian Pharmaceutical Benefits Scheme (PBS) administrative dataset of 118 727 494 GLD prescriptions. The main outcome measures were the annual number of GLD prescriptions dispensed, accounting for type 2 diabetes mellitus (T2DM) prevalence and healthcare system costs, adjusted for inflation. Utilization of GLDs doubled from 6.4 million prescriptions in 2013 to 15.6 million in 2023. The average annual percent increase in utilization was 8.1%, compared to the average annual increase in prevalence of T2DM of 1.8%. The biggest change was in sodium-glucose cotransporter-2 (SGLT2) inhibitors, for which there was an average annual increase in utilization of 59.4% (95% confidence interval [CI] 51.7%, 68.2%; p < 0.05) from 2014 (first full year of PBS listing), followed by glucagon-like peptide-1 receptor agonists (GLP-1RAs), which showed an increase of 31.4% (95% CI 28.5%, 33.8%; p < 0.05) annually (2013 to 2023). Dipeptidyl peptidase-4 inhibitor utilization tripled, with an average annual increase of 10.9% (95% CI 8.1%, 13.8%; p < 0.05), but this plateaued from 2020. Metformin utilization increased by 4.7% (95% CI 2.0%, 6.9%; p < 0.05) annually. In contrast, sulphonylurea, glitazone and acarbose utilization declined. Total GLD costs increased threefold over the same period. Despite only accounting for 11.7% of utilization, GLP-1RAs contributed to 35% of the costs. Utilization of GLDs doubled, and associated costs tripled over the past 11 years, with no sign of either utilization or costs plateauing, predominantly due to increased GLP-1RA and SGLT2 inhibitor prescribing.

Torque Teno Virus Control by the Classical Pathway of Complement Activation-A Retrospective Analysis From a First-in-Human Trial Utilizing Sutimlimab.

Torque Teno virus (TTV) load is linked with the functionality of its host's immune system and has been proposed as a potential monitoring tool for immune-modulating therapy. However, the immunological mechanisms of TTV control are incompletely understood. To assess the effect of the classical complement pathway on TTV, 64 healthy volunteers and 10 kidney transplant recipients treated with the anti-C1s antibody sutimlimab were analyzed for serum TTV copy numbers (c/mL) by qPCR. Overall, a correlation was observed between the decrease in complement activity caused by sutimlimab and the TTV load increase (ρ = -0.367, p < 0.001). Subgroup analysis indicated a trend toward TTV load increase in healthy volunteers following the highest sutimlimab dose compared to baseline (100 mg/kg body weight; median 3.5 log10 c/mL, interquartile range [IQR] 2.8-4.4 vs. 2.9 log10 c/mL, 0.8-3.5; p = 0.063). Administering multiple lower doses (30 mg/kg) also showed a trend toward TTV load increase in healthy volunteers (1.8 log10 c/mL, 0-2.3 vs. 1.9, 1.3-2.8; p = 0.054) and a significant increase in transplant recipients (3.5 log10 c/mL, 3.0-6.1 vs. 4.1, 3.5-6.4; p = 0.004). This report suggests a role for the classical complement pathway in controlling TTV load.

Opioid Prescription Trends Among Sleep Surgeons in the United States.

This study aimed to describe trends in opioid prescriptions among US sleep surgeons between 2013 and 2021 via a retrospective analysis conducted using publicly available data. Utilizing the CMS part D database, we analyzed data from 82 sleep surgeons, focusing on metrics including number of opioid beneficiaries and claims, opioid cost, and opioid day supply per beneficiary. We employed statistical methods including ANOVA, t-tests, Fisher's exact test with Monte Carlo Simulation, and regression models. There were no significant changes in the number of opioid claims (p = 0.782) or beneficiaries per provider (p = 0.590) nor was there a decrease in opioid day supply per beneficiary (p = 0.489) over time. Surgeons who graduated residency before 2000 prescribed significantly more opioids over the course of the study period compared to those graduating after 2000 with higher opioid day supply per beneficiary (13.34 vs. 7.42, p < 0.001), higher opioid beneficiaries per provider (21.62 vs. 19.36, p = 0.028), and higher opioid claims per provider (30.30 vs. 21.78, p < 0.001). A significant annual decrease in opioid cost per beneficiary (ANOVA, p = 0.006) was noted. This study illuminates a significant impact of provider years in practice on opioid prescribing trends, alongside a decreasing trend in opioid cost per beneficiary. Despite the evolving paradigm emphasizing opioid reduction and evidence of decreasing opioid prescriptions in other otolaryngology subspecialties, our findings depict that opioid prescriptions among sleep surgeons remained stable from 2013 to 2021. 3 Laryngoscope, 134:4810-4817, 2024.

Frame-based stereotactic biopsies of brainstem lesions – Monocentric comparison of the transfrontal and the suboccipital-transcerebellar approach over a 16-year period

Both the transfrontal and the suboccipital-transcerebellar approach are frequently used trajectories for frame-based stereotactic biopsies of brainstem lesions. Nevertheless, it remains unclear which approach is more favorable in terms of complications, diagnostic success and outcome, especially considering the location of the lesion within the brainstem. This study compared the safety and diagnostic yield of these two approaches. Furthermore, a brainstem zone model was created to answer the question, whether there is a favorable approach depending on the location of the lesion in the brainstem. A retrospective analysis of 84 consecutive cases of frame-based stereotactic biopsies for brainstem lesions via either transfrontal or suboccipital-transcerebellar approaches over a 16-year period was performed. Clinical and surgical data regarding trajectories, histopathology, complications and outcome was collected. The brainstem was divided in anatomical zones to compare the use of the two approaches depending on the location of the lesions. A total of n = 84 cases of stereotactic biopsies for brainstem lesions were performed. In 36 cases the suboccipital-transcerebellar approach was used, while in 48 cases surgery was performed via the transfrontal approach. The patient’s demographic data were comparable between the two approaches. Overall diagnostic yield was 90.5% (93.8% transfrontal vs. 86.1% suboccipital, p = 0.21, Risk Difference (RD) 0.077, CI [-0.0550, 0.2090]). Complications occurred in 11 cases (total complication rate: 13.1%; 12.5% transfrontal vs. 13.9% suboccipital, p = 0.55, RD 0.014, CI [-0.1607, 0.1327]). The brainstem model showed a more frequent use of the suboccipital approach in lesions of the dorsal pons. The transfrontal approach was used more frequently in mesencephalic targets. No significant differences in terms of complications and diagnostic yield were observed, even though complications in medullary lesions appeared higher using the transfrontal approach. This study showed, that if the approaches are used for their intended target locations there are no significant differences between the transfrontal and the suboccipital-transcerebellar approach for frame-based stereotactic biopsies of brainstem lesions in terms of diagnostic yield and safety. Therefore, our data suggests that both approaches should be considered for stereotactic biopsy of brainstem lesions.

The Role of Radiotherapy in Indolent Ocular Adnexal and Orbital Lymphomas.

This study evaluates the oncological outcomes and toxicities of indolent ocular adnexal and orbital lymphomas (OOLs) treated with radiotherapy (RT) ± systemic therapy. A retrospective analysis of 44 patients with indolent OOLs treated with RT was conducted. Most patients (87%) had early-stage disease. Treatment involved RT alone (34%) or RT + systemic therapy (66%). The median RT dose was 30 Gy, with a median follow-up of 45 months. Local and systemic recurrence rates were 4% and 9%, respectively. Five-year overall and disease-free survival (DFS) rates were 96.2% and 83.6%. Early-stage patients showed similar DFS rates regardless of whether they received RT alone or RT plus systemic therapy. No grade 3 RT-related toxicity occurred, but systemic therapy led to grade 3 toxicity in 17% of patients. RT is essential for treating indolent OOLs, and combination with systemic therapies does not enhance outcomes for early-stage patients.

Comparative analysis of stereotactic radiosurgery outcomes for supratentorial hemangioblastomas in von hippel-lindau disease and sporadic cases: A multi-center international study

BackgroundHemangioblastomas (HBs) are rare, benign central nervous system (CNS) neoplasms that rarely occur in the supratentorial. Resection with the goal of gross total resection (GTR) is often considered the primary treatment. Stereotactic radiosurgery (SRS) has been utilized more commonly in unresectable or partially resected cases. In this study, we aimed to evaluate SRS’s effectiveness and clinical outcomes in supratentorial HBs. MethodsA retrospective analysis of multi-centers from 1993 to 2022 was conducted on patients with supratentorial HB treated with SRS. ResultsThe study included 13 patients with 30 supratentorial HBs (24 von Hippel-Lindau (VHL), 6 sporadic). Median age was 26 years. Most tumors were solid (86.2 %). SRS was primary treatment in 86.7 % of cases and adjuvant in 13.3 %. VHL lesions were significantly smaller than sporadic ones (0.2 vs. 3.7 cc, p = 0.009). Median margin dose was higher in VHL cases (17 vs. 13.0 Gy, P = 0.031). For VHL cases, local control (LC) was 100 % at 6 months, 96 % (95 % CI: 88 %, 100 %) from 12 to 60 months post-SRS. For sporadic cases, LC was 100 % at 6 months, 80 % (95 % CI: 52 %, 100 %) from 12 to 60 months post-SRS (p = 0.39). No adverse radiation events or mortality occurred. ConclusionSRS demonstrated a promising role in the clinical course of supratentorial HBs. It can be considered an effective alternative to surgical resection and even a first-line therapeutic option in appropriately selected cases.
