The impact of awake prone positioning (APP) on clinical outcomes in patients with COVID-19 and acute hypoxemic respiratory failure (AHRF) remains uncertain. To assess the association of APP with improved clinical outcomes among patients with COVID-19 and AHRF, and to identify potential effect modifiers. PubMed, Embase, the Cochrane Library, and ClinicalTrials.gov were searched through August 1, 2024. Randomized clinical trials (RCTs) examining APP in adults with COVID-19 and AHRF that reported intubation rate or mortality were included. Individual participant data (IPD) were extracted according to PRISMA-IPD guidelines. For binary outcomes, logistic regression was used and odds ratio (OR) and 95% CIs were reported, while for continuous outcomes, linear regression was used and mean difference (MD) and 95% CIs were reported. The primary outcome was survival without intubation. Secondary outcomes included intubation, mortality, death without intubation, death after intubation, escalation of respiratory support, intensive care unit (ICU) admission, time from enrollment to intubation and death, duration of invasive mechanical ventilation, and hospital and ICU lengths of stay. A total of 14 RCTs involving 3019 patients were included; 1542 patients in the APP group (mean [SD] age, 59.3 [14.1] years; 1048 male [68.0%]) and 1477 in the control group (mean [SD] age, 59.9 [14.1] years; 979 male [66.3%]). APP improved survival without intubation (OR, 1.42; 95% CI, 1.20-1.68), and it reduced the risk of intubation (OR, 0.70; 95% CI, 0.59-0.84) and hospital mortality (OR, 0.77; 95% CI, 0.63-0.95). APP also extended the time from enrollment to intubation (MD, 0.93 days; 95% CI, 0.43 to 1.42 days). In exploratory subgroup analyses, improved survival without intubation was observed in patients younger than age 68 years, as well as in patients with a body mass index of 26 to 30, early implementation of APP (ie, less than 1 day from hospitalization), a pulse saturation to inhaled oxygen fraction ratio of 155 to 232, respiratory rate of 20 to 26 breaths per minute (bpm), and those receiving advanced respiratory support at enrollment. However, none of the subgroups had significant interaction with APP treatment. APP duration 10 or more hours/d within the first 3 days was associated with increased survival without intubation (OR, 1.85; 95% CI, 1.37-2.49). This IPD meta-analysis found that in adults with COVID-19 and AHRF, APP was associated with increased survival without intubation and with reduced risks of intubation and mortality, including death after intubation. Prolonged APP duration (10 or more hours/d) was associated with better outcomes.

BackgroundCholecystectomy and common bile duct exploration for biliary stone disease are common hepatobiliary surgeries performed by general surgeons in Nigeria. These procedures can be complicated by injury to the biliary tree or retained stones, requiring repeat surgical intervention. This study presents the experience of using endoscopic retrograde cholangiopancreatography (ERCP) in the management of hepatobiliary surgery complications at the academic referral center of Obafemi Awolowo University Teaching Hospital (OAUTHC) Ile-Ife, Nigeria.MethodsAll patients with postcholecystectomy complications referred to the endoscopy unit at OAUTHC from March 2018 to April 2023 were enrolled. Preoperative imaging included a combination of abdominal ultrasound, CT, MRI, magnetic resonance cholangiopancreatography (MRCP), and T-tube cholangiogram. All ERCP procedures were performed under general anesthesia.ResultsSeventy-two ERCP procedures were performed on 45 patients referred for postcholecystectomy complications. The most common mode of presentation was ascending cholangitis [16 (35.6%)], followed by persistent biliary fistula [12 (26.7%)]. The overall median duration of symptoms after cholecystectomy was 20 weeks, with a range of 1-162 weeks. The most common postcholecystectomy complication observed was retained stone [16 (35.6%)]. Other postcholecystectomy complications included bile leakage, bile stricture, bile leakage with stricture, and persistent bile leakage from the T-tube in 12 (26.7%), 11 (24.4%), 4 (8.9%), and 2 (4.4%) patients, respectively. Ampullary cannulation during ERCP was successful in all patients (45, 100%). Patients with complete biliary stricture (10/12) required hepaticojejunostomy.ConclusionEndoscopic management of postcholecystectomy complications was found to be safe and reduce the number of needless surgeries to which such patients are exposed. We recommended prompt referral of such patients for ERCP.

In the United States, hepatitis C virus-associated hepatocellular carcinoma incidence and mortality are highest among minorities. Socioeconomic constraints play a major role in inequitable treatment. We evaluated the association between race/ethnicity and outcomes in a population that overcame treatment barriers. We report a retrospective cohort study of 666 patients across 20 institutions in the United States Hepatocellular Carcinoma Liver Transplantation Consortium from 2015 to 2019 with hepatitis C virus-associated hepatocellular carcinoma who completed direct-acting antiviral therapy and underwent liver transplantation. Patients were excluded if they had a prior liver transplantation, hepatocellular carcinoma recurrence, no prior liver-directed therapy, or if race/ethnicity data were unavailable. Patients were stratified by race/ethnicity. Primary outcomes were recurrence-free survival and overall survival, and secondary outcome was major postoperative complication. Race/ethnicity was not associated with differences in 5-year recurrence-free survival (White 90%, Black 88%, Hispanic 92%, Other 87%; p = 0.85), overall survival (White 85%, Black 84%, Hispanic 84%, Other 93%; p = 0.70), or major postoperative complication. Race/ethnicity was not associated with worse oncologic or postoperative outcomes among those who completed direct-acting antiviral therapy and underwent liver transplantation, suggesting that overcoming socioeconomic constraints equalizes outcomes across racial/ethnic groups. Eliminating barriers that prohibit care access among minorities must be a priority.

Target population These recommendations apply to adult patients with recurrent WHO grade 2 infiltrative diffuse glioma (oligodendroglioma, astrocytoma).Questions and Recommendations:Imaging Q1: In adult patients with suspected recurrence of histologically proven WHO grade 2 diffuse glioma, do advanced imaging techniques using magnetic resonance spectroscopy, perfusion weighted imaging, diffusion weighted imaging or PET provide superior assessment of tumor recurrence and histologic progression compared to standard MRI neuroimaging?Recommendation Level III: In adult patients with suspected recurrence of histologically proven WHO grade 2 diffuse glioma, advanced imaging techniques using magnetic resonance spectroscopy, perfusion weighted imaging, diffusion weighted imaging or PET are suggested for identification of tumor recurrence or histologic progression.Pathology Q1: In adult patients with suspected recurrence of histologically proven WHO grade 2 diffuse glioma, is molecular testing for IDH-1, IDH-2, and TP53 Mutations and MGMT promotor methylation mutation warranted for predicting survival and formulating treatment recommendations?Recommendation Level III: It is suggested that IDH mutation status be determined for diagnostic purposes. TP53 mutations occur early in WHO grade 2 diffuse glioma pathogenesis, remain stable, and are not suggested as a marker of predisposition to malignant transformation at recurrence or other measures of prognosis. Assessment of MGMT status is suggested as an adjunct to assessing prognosis. Assessment of CDK2NA status is suggested since this is associated with malignant progression of WHO grade 2 diffuse gliomas.Q2: In adult patients with suspected recurrence of histologically proven WHO Grade 2 diffuse glioma, is testing of proliferation indices (MIB-1 and/or BUdR) warranted for predicting survival and formulating treatment recommendations?Recommendation Level III: It is suggested that proliferative indices (MIB-1 or BUdR) be measured in WHO grade 2 diffuse glioma as higher proliferation indices are associated with increased likelihood of recurrence and shorter progression free and overall survival.Chemotherapy Q1: In adult patients with suspected recurrence of histologically proven WHO grade 2 diffuse glioma, does addition of temozolomide (TMZ), other cytotoxic agents or targeted agents to their treatment regimen improve PFS and/or OS?Recommendation Level III: Temozolomide is suggested in the therapy of recurrent WHO grade 2 diffuse glioma as it may improve clinical symptoms. PCV is suggested in the therapy of WHO grade 2 diffuse glioma at recurrence as it may improve clinical symptoms with the strongest evidence being for oligodendrogliomas. TMZ is suggested as the initial choice for recurrent WHO grade 2 diffuse glioma. Carboplatin is not suggested as there is no significant benefit from carboplatin as single agent therapy for recurrent WHO grade 2 diffuse gliomas. There is insufficient evidence to make any recommendations regarding other agents in the management of recurrent WHO grade 2 diffuse glioma.Radiotherapy Q1: In adult patients with suspected recurrence of histologically proven WHO grade 2 diffuse glioma, does addition of radiotherapy to treatment regimen improve PFS and/or OS?Recommendation Level III: Radiation is suggested at recurrence if there was no previous radiation treatment. Q2: In adult patients with suspected recurrence of histologically proven WHO grade 2 diffuse glioma after previous radiotherapy, does addition of re-irradiation or proton therapy to the treatment regimen improve PFS and/or OS?Recommendation Level III: It is suggested that re-irradiation be considered in the setting of WHO grade 2 diffuse glioma recurrence as it may provide benefit in PFS and OS.Surgery Q1: In adult patients with suspected recurrence of histologically proven WHO grade 2 diffuse glioma, does surgical resection improve PFS and/or OS?. There is insufficient evidence to make any new specific recommendations regarding the value of surgery or extent of resection in relationship to survival for recurrent WHO grade 2 diffuse glioma.

Hyperglycemia-induced involuntary movements (HIIM) include tremors,hemichorea-hemiballismus (HCHB), and more rarely, dystonia.Presentations may vary, but hyperintensityinvolving the basal ganglia area on the T1 sequence of MRI brain remains a commonality. We report the occurrence of focal dystonia with uncontrolled hyperglycemia but no focal abnormalities on MRI. On admission, the patient's blood glucose was861, and she claimed to have never missed insulin dosage. A physical exam revealed no cranial nerve abnormalities and weakness in the right upper extremitywith no sensory involvement. Reflexes were 1-2+ in all extremities with down-going toes. The abnormal movementswere triggered by overhead abduction of the right arm. Symptoms improved after a week with blood glucose control, as well asbenzodiazepines and anticholinergics. This specific case emphasizes the occurrence of uncontrolled hyperglycemia causing movement disorders that can have normal imaging findings. Understanding the complex presentation of patients with HIIM is pivotal for effective patient diagnosis and treatment.

Allergic rhinitis (AR), a condition characterized by sensitivity to allergens leading to poor quality of life, including disrupted sleep, reduced vitality, lowered mood, changes in blood pressure limited frustration tolerance, impaired focus, decreased performance in academic and professional settings, and millions of missed work and school days every year. Approximately 20–40% of individuals in the United States are affected by AR, which carries notable clinical and financial burdens. Interestingly, there is a strong link between AR and asthma to the extent that countries with a high prevalence of rhinitis have asthma rates ranging from 10% to 25%. Research has indicated that Allergen Immunotherapy (AIT) is associated with improved AR symptoms, a potential to resolve the AR over time, a decreased likelihood of asthma exacerbations and incidence of pneumonia in individuals with concurrent asthma, which are advantages that persist for years even after the cessation of treatment. Although patients presenting with allergies are first seen and treated in the primary care setting, gaps in training and the lack of available guidance for primary care practitioners have significantly impacted the quality of care for these patients with persistent AR symptoms, resulting in inefficient use of healthcare resources. To complicate matters, there is an insufficiency of allergists and immunologists, impacting the capacity to provide next-level care to the number of AR patients who could benefit from AIT. Hence, there is a critical need to equip primary care providers with educational experiences on essential concepts related to immune responses in allergies and asthma, recognizing the significance of the common airway in treating these entities and familiarization with the scientific evidence supporting various options for AIT. The development and implementation of medical education and algorithms designed to assess diverse patients’ symptoms, pharmacotherapy approaches, and situations where AIT can be initiated or sustained are warranted. The present commentary proposes a workflow model of the critical steps for managing and treating mild to moderate respiratory allergies via AIT in primary care settings. In addition, the initial development of medical education programs to minimize the burden on allergy-specialized care while, importantly, actively improving patient outcomes will be discussed.

e14028 Background: For 70 years, the best indicator of glioblastoma (GBM) survival has remained age at diagnosis. Factors across the entire genome affect every aspect of the disease. But typical artificial intelligence and machine learning (AI/ML) would require 3B-patient training sets to generate predictive models from the whole 3B-nucleotide genome. As a result, all other attempts to associate a tumor’s DNA copy-number alterations (CNAs) with the patient’s outcome failed. Methods: A genome-wide pattern of DNA CNAs in primary GBM tumors was recently validated in a retrospective clinical trial as the most accurate and precise predictor of survival and response to treatment [doi: 10.1063/1.5142559 ]. Applicable to the general population, this biomarker, the first to encompass the whole genome, and biomarkers in lung, nerve, ovarian, and uterine cancers, were repeatedly identified in open-source datasets from as few as 50–100 patients by using our data-agnostic unsupervised AI/ML, which extends the mathematics of quantum mechanics to overcome the limitations of typical AI/ML [doi: 10.1063/1.5099268 , 10.1073/pnas.0530258100 ]. Results: At 75–95% concordance, our biomarker is more accurate than and independent of age and all other indicators, including the one-gene tests for MGMT, IDH1, and TERT. Platform- and reference genome-agnostic, the biomarker’s >99% precision is greater than the community consensus of <70% reproducibility. It describes disease mechanisms and identifies drug targets and combinations of targets to sensitize tumors to treatment. Now, in follow-up results from the trial we, first, show correct prospective prediction of the outcome of the five of the 79 patients who were alive four years earlier, at the time of first results (log-rank P-value=3.9×10–2). Two patients, who were predicted to have shorter survival, lived less than five years from diagnosis, whereas of the three patients predicted to have longer survival, one lived more than five, and the remaining two are alive >11.5, years from diagnosis. Second, we demonstrate 100%-precise clinical prediction for the 59/79 patients with remaining tumor DNA, by using whole-genome sequencing in a Clinical Laboratory Improvement Amendments (CLIA)/College of American Pathologists (CAP) laboratory. Third, we establish that the risk that a tumor’s whole genome confers upon outcome, as is reflected by the biomarker’s univariate Cox hazard ratio of 4.2 and Kaplan-Meier median survival difference of 2.25 years (log-rank P-value=6.0×10–4), is greater than that conferred by the patient’s Karnofsky performance score and access to chemotherapy, and the tumor’s percent resection, and is surpassed only by the patient’s access to radiotherapy. Conclusions: This is a proof of principle that our AI/ML is uniquely suited for personalized medicine.
