The expression of SLC7A11, the cystine/glutamate transporter, was identified as a superior determinant of response to APR-246. Genetic regulators of SLC7A11, including ATF4, MDM2, wild-type p53, and c-Myc, were confirmed to also regulate cancer-cell sensitivity to APR-246. In conclusion, SLC7A11 expression is a broadly applicable determinant of sensitivity to APR-246 across cancer and should be utilized as the key predictive biomarker to stratify patients for future clinical investigation of APR-246.Lung cancers harboring mesenchymal-to-epithelial transition factor (MET) genetic alterations, such as exon 14 skipping mutations or high-level gene amplification, respond well to MET-selective tyrosine kinase inhibitors (TKI). However, these agents benefit a relatively small group of patients (4%-5% of lung cancers), and acquired resistance limits response durability. An antibody-drug conjugate (ADC) targeting MET might enable effective treatment of MET-overexpressing tumors (approximately 25% of lung cancers) that do not respond to MET targeted therapies. Using a protease-cleavable linker, we conjugated a biparatopic METxMET antibody to a maytansinoid payload to generate a MET ADC (METxMET-M114). METxMET-M114 promotes substantial and durable tumor regression in xenografts with moderate to high MET expression, including models that exhibit innate or acquired resistance to MET blockers. Positron emission tomography (PET) studies show that tumor uptake of radiolabeled METxMET antibody correlates with MET expression levels and METxMET-M114 efficacy. In a cynomolgus monkey toxicology study, METxMET-M114 was well tolerated at a dose that provides circulating drug concentrations that are sufficient for maximal antitumor activity in mouse models. Our findings suggest that METxMET-M114, which takes advantage of the unique trafficking properties of our METxMET antibody, is a promising candidate for the treatment of MET-overexpressing tumors, with the potential to address some of the limitations faced by the MET function blockers currently in clinical use.
There is international variation in hospital admission practices for patients with mild traumatic brain injury (TBI) and injuries on CT scan. Only a small proportion of patients require neurosurgical intervention, while many guidelines recommend routine admission of all patients. We aim to validate the Hull Salford Cambridge Decision Rule (HSC DR) and the Brain Injury Guidelines (BIG) criteria to select low-risk patients for discharge from the emergency department.

A cohort from 18 countries of Glasgow Coma Scale 13-15 patients with injuries on CT imaging was identified from the multicentre Collaborative European NeuroTrauma Effectiveness Research in TBI (CENTER-TBI) Study (conducted from 2014 to 2017) for secondary analysis. A composite outcome measure encompassing need for ongoing hospital admission was used, including seizure activity, death, intubation, neurosurgical intervention and neurological deterioration. We assessed the performance of our previously derived prognostic model, the HSC DR and the o be discharged, none of whom would have deteriorated. Use of the BIG criteria may select patients for discharge who have too high a risk of subsequent deterioration to be used clinically. Further validation and implementation studies are required to support use in clinical practice.
Research focused on postoperative outcomes among men and women undergoing minimally invasive lumbar decompression (MIS LD) spine surgery is sparse. This study aims to assess the influence of sex on postoperative patient-reported outcome measure (PROM) evaluations and achievement of a minimum clinically important difference (MCID).

A prospectively maintained surgical database was retrospectively queried for patients undergoing primary or revision, single or multilevel LD procedures from 2011 to 2019. Patients with incomplete visual analog scale (VAS) leg or back surveys were excluded. Demographic and operative variables were recorded, and a chi-squared analysis or
tests were used to compare by sex. PROMs were evaluated from preoperative to postoperative time points. PROM score differences and postoperative improvement were evaluated between sexes by a
test. Achievement of MCID by sex was compared using chi-squared analysis.

The study cohort (
= 572) was 70% male (
= 398), had an average age of 47 years, and 42% were obese. Sexes differed in preoperative VAS leg, Oswestry Disability Index (ODI), and 12-item short form (SF-12)-physical composite score (PCS) scores (all
< .05) and in ODI at 6 and 12 weeks (
= .048;
= .001) and VAS back and leg scores at 6 months (
= .039;
= .019). Both sexes significantly improved (
< .050) all PROMs at all time points except for VAS back at 1 year for women and ODI at 6 weeks and 6 months for men. The only significant difference in achievement of MCID was for ODI at 6 months (
= .008).

Significant preoperative differences were observed among sexes with ODI, SF-12-PCS, and VAS leg scores. By 1 year, there were no significant sex differences for any PROM or for achievement of MCID. MIS LD has an equivalent role for both sexes in achieving MCID.

Studies reporting multilevel anterior cervical corpectomy (>2 levels) and reconstruction in patients with long-segment anterior cervical compression are few and surgical outcomes are variable with increased surgical morbidity and a high incidence of graft-related complications. The aim of this study is to evaluate the effectiveness and safety of cervical corpectomy and anterior reconstruction of 3 or more levels in patients with long-segment anterior cervical compression.

We retrospectively reviewed patients who had undergone 3 or more levels of anterior cervical corpectomy and reconstruction from 2014 to 2018. Clinical and radiological parameters such as Nurick grading, modified Japanese Orthopedic Association (mJOA) score, cervical segmental angle, cervical sagittal angle, graft subsidence, and fusion rate were evaluated preoperatively and at a 2-year follow-up. Patients were divided into 2 groups according to their anterior reconstruction, either with fibular strut autogenous graft or titanium mesh follow-up.

Multilevel anterior cervical corpectomy and reconstruction is a safe and efficacious procedure. A titanium mesh cage filled with autogenous bone graft and a rigid anterior cervical plate gives best results. Posterior instrumentation should be considered along with a multilevel cervical corpectomy construct in patients with poor bone stock.

The design is a retrospective cohort study. Charcot spinal arthropathy (CSA) is a rare and poorly understood progressive destructive spine condition that usually affects patients with preexisting spinal cord injury. The complexity of this condition, especially when additionally burdened by superimposed infection in the CSA zone, can potentially lead to suboptimal management such as protracted antibiotic therapy, predisposition to hardware failure, and pseudarthrosis. While in noninfected CSA primary stabilization is the major goal, staged surgical management has not been stratified based upon presence of a superinfected CSA. We compare clinical and radiological outcomes of surgical treatment in CSA patients with and without concurrent spinal infections.

Our single-institution database was reviewed for all patients diagnosed with CSA and surgically treated, who were subsequently divided into 2 cohorts spinal arthropathy with superimposed infection and those without. Those were comparatively studied for com surgical treatment of CSA.
The proposed treatment algorithm including the use of a quadruple-rod construct with lumbopelivic fixation and a staged approach in patients with superinfected CSA represents a reasonable option in the surgical treatment of CSA.Morning glory disc (MGD) is known to develop secondary maculopathy and vision loss. We followed a 7-year-old girl with MGD in right eye from 2010 to 2021. Her best-corrected Snellen visual acuity (BCVA) was 20/20 in both eyes till 2017. She presented with reduced vision in right eye with BCVA of 20/80 in 2018. Optical Coherence Tomography (OCT) revealed maculopathy related to MGD in right eye and arcuate Vitelliform neurosensory detachment (V-NSD) temporal to fovea. She underwent 25G vitrectomy with internal limiting membrane peeling. Resolution of retinoschisis and V-NSD was analysed by OCT and fundus autofluorescence (FAF) postoperatively. Arcuate V-NSD was hyperfluorescent on FAF and concentric to optic disc. It resolved slowly with BCVA improving to 20/20 at 18 and 30 months postoperatively. We report excellent outcome following early vitrectomy for MGD-related maculopathy and recommend serial follow-up and considering early vitrectomy whenever traction and BCVA worsens. We also describe arcuate V-NSD with MGD.A 54-year-old male patient applied to our clinic with a sudden and painless loss of vision in his right eye. He was suffering from COVID-19. selleck kinase inhibitor His best-corrected visual acuity of the right eye was finger counting from 30 cm. The fundus examination revealed the presence of a 'cherry-red spot' appearance in the right eye. In optical coherence tomography imaging, hyper-reflectivity was observed in the inner retinal layers as well as increased retinal thickness in the right eye. In fundus fluorescein angiography, delayed arterial filling and prolonged arteriovenous transit time were observed in the right eye. The patient was diagnosed with central retinal artery occlusion after the COVID-19 infection. In this study, we report this case and its management.Atrial septal defect (ASD) is the most common congenital heart disease observed in adult. Several ECG findings are considered sensitive for the diagnosis of ASD. We describe a 50 years old man who displayed Crochetage sign, incomplete right bundle branch block (IRBBB) and right ventricular strain pattern on ECG. Crochetage sign is highly specific for ASD and it correlates with shunt severity. The diagnostic specificity for ASD increases if the R waves have both Crochetage patterns and IRBBB. It is important not to confuse Crochetage signs with IRBBB abnormalities on ECG. Our patient was ultimately diagnosed with a large ASD measuring 3 cm with bidirectional shunt and concomitant pulmonary thrombosis. This illustrates that high suspicion of the ASD with the use of good-old ECG signs remains relevant in this modern era. This also reminds us that patients with Eisenmenger syndrome are at higher risk for pulmonary thrombosis.Myopathy and peritoneal involvement are rare complications of sarcoidosis, and the latter can mimic malignancy with peritoneal dissemination. In this case, a patient with a history of polyarthritis and positive rheumatoid factor presented with proximal muscle weakness and abdominal pain. Biopsies of muscle and peritoneum revealed non-caseating granuloma suggesting sarcoidosis. Ocular and pulmonary involvement later developed and confirmed the diagnosis of sarcoidosis.A 51-year-old woman presented with a 2-week history of off balance, left lower limb weakness and neglect and neck pain radiating down the right arm. Investigations revealed a metastatic, ROS1 fusion-positive, non-small cell lung cancer, and treatment with entrectinib, a recently approved multikinase inhibitor, was started. Two weeks after, she was admitted to the emergency department with new-onset pressure-like chest pain and dyspnoea. Laboratory evaluation showed elevated troponin and mild left ventricular systolic dysfunction with reduced global longitudinal strain on transthoracic echocardiogram. Cardiac magnetic resonance revealed mild oedema and non-ischaemic fibrosis. A diagnosis of drug-induced myocarditis was made. Cardioprotective medication with an angiotensin-converting enzyme inhibitor and a beta-blocker was started. Entrectinib was temporarily discontinued and restarted at a reduced dose after a multidisciplinary team meeting involving both the oncology and cardio-oncology teams. This is the second described case of entrectinib-induced myocarditis and the first one without eosinophilia.
