Objective:
: Glioblastoma multiforme (GBM), particularly the isocitrate dehydrogenase (IDH)-wildtype type, represents a significant clinical challenge due to its aggressive nature and poor prognosis. Despite advancements in medical imaging and its modalities, survival rates have not improved significantly, demanding innovative treatment planning and outcome prediction approaches.
Methods:
: This study utilizes a support vector machine (SVM) classifier using radiomics features to predict the overall survival (OS) of GBM, IDH-wildtype patients to short (<12 months) and long (≥12 months) survivors. A dataset comprising multi-parametric magnetic resonance imaging scans from 574 patients was analyzed. Radiomic features were extracted from T1, T2, fluid-attenuated inversion recovery, and T1 with gadolinium (T1GD) sequences. Low variance features were removed, and recursive feature elimination was used to select the most informative features. The SVM model was trained using a k-fold cross-validation approach. Furthermore, clinical parameters such as age, gender, and MGMT (O6-methylguanine-DNA methyltransferase) promoter methylation status were integrated to enhance prediction accuracy.
Results:
: The model showed reasonable results in terms of cross-validated area under the curve of 0.84 (95% confidence interval, 0.80–0.90) with (p<0.001) effectively categorizing patients into short and long survivors. Log-rank test (chi-square statistics) analysis for the developed model was 0.00029 along with the 1.20 Cohen’s d effect size. Most importantly, clinical data integration further refined the survival estimates, providing a more fitted prediction that considers individual patient characteristics by Kaplan-Meier curve with p-value <0.0001.
Conclusion
: The proposed method significantly enhances the predictive accuracy of OS outcomes in GBM, IDH-wildtype patients. By integrating detailed imaging features with key clinical indicators, this model offers a robust tool for personalized treatment planning, potentially improving OS.

Hepatocellular carcinoma (HCC) with portal vein tumor thrombosis (PVTT) is associated with a dismal prognosis. Atezolizumab plus bevacizumab (atezo-bev) is the recommended palliative treatment, and approximately 10% of the patients may experience a complete response (CR), according to the mRECIST criteria. The treatment duration is until disease progression or unacceptable side effects occur. Long-term continuation can cause potential toxicities and a substantial financial burden, making early treatment discontinuation a viable option. This report describes durable CR after discontinuing atezo-bev treatment in three patients with HCC and PVTT.

Surgery for a symptomatic epiphrenic esophageal diverticulum (EED) typically involves a diverticulectomy with myotomy and partial fundoplication. A 54-year-old male patients presented with postprandial retrosternal pain and regurgitation. A contrast-enhanced computed tomography scan revealed an 8 × 6 × 7 cm left-sided EED. We planned the EED excision using the da Vinci Xi robot (Intuitive Surgical) from an abdominal transhiatal approach.The lower esophagus was looped, followed by the mobilization of the diverticulum and division of its neck using a robotic stapler. A 7-cm long esophagogastric myotomy was performed on the right side with a Toupet fundoplication. The total operative time was 240 minutes with a blood loss of 200 mL. An oral contrast study on postoperative day 1 showed no leak, and the patient was discharged the next day on an oral soft diet. The robotic transhiatal approach to treat EED is safe and may successfully overcome the difficulties of exposure and reach encountered in conventional laparoscopic surgery.

Objective:
Colony-stimulating factor 1 receptor-related leukoencephalopathy (CSF1R-L) is a rare adult-onset leukoencephalopathy. Reports of CSF1R-L patients from the Indian subcontinent remain limited. We aimed to report four patients with genetically confirmed CSF1R-L from four Asian Indian families and described their clinical, molecular, and radiological features.
Methods:
All patients underwent clinical examination, brain magnetic resonance imaging, and whole-exome sequencing to identify causative variants in the CSF1R gene. We also reviewed published reports of Indian patients with CSF1R-L.
Results:
The age at enrollment ranged from 34 to 40 years. The duration of symptoms ranged from 11 months to 2 years. The chief clinical phenotype in three patients was a rapidly evolving cognitive-behavioral syndrome combined with atypical parkinsonism, and asymmetrical spastic tetraparesis was observed in one patient. We identified four different variants (three missense variants and one in-frame deletion). Radiological findings revealed white matter involvement and diffusion restriction involving the subcortical white matter and pyramidal tracts.
Conclusion
We expand the literature on CSF1R-L patients from India by reporting four new cases.

Objective:
To explore sleep patterns in individuals with essential tremor (ET) and essential tremor plus (ET-Plus) compared with healthy controls and assess differences between ET and ET-Plus, given the lack of established polysomnography (PSG) data on these groups and the potential for sleep disturbances to serve as clinical markers.
Methods:
We conducted a prospective cross-sectional study at National Institute of Mental Health and Neurosciences, Bengaluru, from November 2021 to August 2023 on 45 patients (26 ET, 19 ET-Plus) and 45 controls. Tremor severity was assessed using The Essential Tremor Rating Assessment Scale (TETRAS) and Fahn‐Tolosa‐Marin Clinical Rating Scale (FTMRS). Sleep symptoms were assessed via the Epworth Sleepiness Scale, Pittsburgh Sleep Quality Index, Mayo Sleep Questionnaire, restless legs syndrome questionnaire, Berlin questionnaire, Generalized Anxiety Disorder Scale 7, and Patient Health Questionnaire-9. All patients and controls underwent overnight video PSG. Sleep scoring was manually performed by a trained sleep research technician and the first author following the American Academy of Sleep Medicine (2017) guidelines, with data analyzed using R studio.
Results:
Compared with ET-Plus patients, ET patients had a younger onset age (46.8±11.1 years versus 30.8±16.7 years, respectively). Compared with ET patients, ET-Plus patients had higher TETRAS and FTMRS scores (p<0.005). Compared with controls, both ET patients and ET-Plus patients presented poorer sleep quality, excessive daytime sleepiness, rapid eye movement (REM) sleep behavior disorder, and restless legs syndrome symptoms. PSG findings supported these clinical observations, showing an elevated apnea‒hypopnea index, reduced total sleep time, prolonged REM latency, decreased sleep efficiency, increased N1 stage duration, and reduced N2/N3 durations and percentages in patients versus controls.
Conclusion
The study highlights significant sleep architecture abnormalities in both ET and ET-Plus patients compared with healthy controls, with no differences between the ET groups.

Obstructive sleep apnea (OSA) is a multi-level airway disease, and the specific site of obstruction may influence associated conditions such as eustachian tube dysfunction (ETD) and gastroesophageal reflux disease (GERD). This study aimed to explore the relationship between OSA, ETD, acid reflux, and the anatomical site of obstruction. Methods: Participants were assessed using validated questionnaires for OSA, ETD, and reflux symptoms. The site of upper airway collapse was determined objectively using apneagraphy or sleep MRI. Acid reflux symptoms were evaluated using a standardized reflux symptom questionnaire, and 24-hour pH monitoring was done when indicated. ETD was assessed both subjectively and objectively through the Toynbee maneuver. Results: Sixty-three individuals completed the evaluation. The mean age was 40.4 years, and the mean BMI was 28.1 kg/m2. Retroglossal obstruction was observed in 76.1% (48/63), while 23.9% (15/63) had retropalatal obstruction. ETD was diagnosed in 53% of participants, and GERD in 38% by objective testing. A statistically significant association was found between retroglossal collapse and complete ETD (p=0.02). However, no significant link was noted between the obstruction site and laryngopharyngeal reflux or partial ETD. Additionally, salivary pepsin levels showed no correlation with reflux (p=0.412). Conclusions: OSA is frequently accompanied by ETD and GERD. Notably, retroglossal obstruction appears to be significantly associated with complete ETD, suggesting a potential site-specific impact. These findings underscore the importance of anatomical localization in understanding OSA-related comorbidities and warrant further investigation in larger multicenter studies.
