The health-beneficial effects of nutraceuticals in various diseases have received enhanced attention in recent years. Aging is a continuous process wherein physiological activity of an individual declines over time and is characterized by various indefinite hallmarks which contribute toward aging-related comorbidities in an individual which include many neurodegenerative diseases, cardiac problems, diabetes, bone-degeneration, and cancer. Cellular senescence is a homeostatic biological process that has an important function in driving aging. Currently, a growing body of evidence substantiates the connection between epigenetic modifications and the aging process, along with aging-related diseases. These modifications are now being recognized as promising targets for emerging therapeutic interventions. Considering that almost all the biological processes are modulated by RNAs, numerous RNA-binding proteins have been found to be linked to aging and age-related complexities. Currently, studies have shed light on the ability of the nutraceutical Withania somnifera (Ashwagandha) to influence RNA expression, stability, and processing, offering insights into its mechanisms of action. By targeting RNA-related pathways, Withania somnifera may exhibit promising effects in ameliorating age-associated molecular changes, which include modifications in gene expression and signaling networks. This review summarizes the potential role of Withania somnifera as a nutraceutical in modulating RNA-level changes associated with aging, encompassing both in vitro and in vivo studies. Taken together, the putative role(s) of Withania in modulation of key RNAs will provide insights into understanding the aging process and facilitate the development of various preventive and therapeutic strategies employing nutraceuticals for healthy aging.

Inflammaging, a coexistence of inflammation and aging, is a persistent, systemic, low-grade inflammation seen in the geriatric population. Various natural compounds have been greatly explored for their potential role in preventing and treating inflammaging. Withania somnifera has been used for thousands of years in traditional medicine as a nutraceutical for its numerous health benefits including regenerative and adaptogenic effects. Recent preclinical and clinical studies on the role of Withania somnifera and its active compounds in treating aging, inflammation, and oxidative stress have shown promise for its use in healthy aging. We discuss the chemistry of Withania somnifera, the etiology of inflammaging and the protective role(s) of Withania somnifera in inflammaging in key organ systems including brain, lung, kidney, and liver as well as the mechanistic underpinning of these effects. Furthermore, we elucidate the beneficial effects of Withania somnifera in oxidative stress/DNA damage, immunomodulation, COVID-19, and the microbiome. We also delineate a putative protein–protein interaction network of key biomarkers modulated by Withania somnifera in inflammaging. In addition, we review the safety/potential toxicity of Withania somnifera as well as global clinical trials on Withania somnifera. Taken together, this is a synthetic review on the beneficial effects of Withania somnifera in inflammaging and highlights the potential of Withania somnifera in improving the health-related quality of life (HRQoL) in the aging population worldwide.

Background The safety and efficacy of endovascular thrombectomy (EVT) in patients with acute ischemic stroke due to large vessel occlusion presenting beyond 24 hours from last known well (LKW) remains undetermined. Methods In this single center study, we identified patients with large vessel occlusion who were eligible for EVT based on noncontrast computed tomography (CT)/CT angiography (without CT perfusion or magnetic resonance imaging) using an Alberta Stroke Program Early CT Score of ≥5, National Institutes of Health Stroke Scale of ≥6, and presenting beyond 24 hours from LKW, between January 2018 and March 2022. During the study period, EVT service limitations meant patients eligible for EVT presenting outside service hours, routinely received best medical management (BMM). Functional and safety outcomes were compared between patients receiving EVT or BMM following multivariable adjustment for age, baseline stroke severity, Alberta Stroke Program Early CT Score, time from LKW, IV thrombolysis, and clot location. Results Among 35 patients presenting beyond 24 hours from LKW and eligible for EVT, 19 (54%) were treated with EVT and 16 (46%) with BMM. Alberta Stroke Program Early CT Score were similar across both groups (EVT: 7 [6.75–8] versus BMM: 7 [6–8]), but not the baseline National Institutes of Health Stroke Scale (EVT: 17 [11–19.5] versus BMM: 20 [9.75–26]). No significant difference was observed between the EVT and BMM groups in the symptomatic intracranial hemorrhage (5.3% versus 0%; P=0.28) or mortality (26.3% versus 37.5%; P=0.42) rates, respectively. The modified Rankin scale at 90 days (adjusted common odds ratio [OR], 1.94; [95% CI 0.42–8.87]; P=0.39) and functional independence rate, although numerically higher in the EVT group compared with the BMM group (modified Rankin scale≤2; 36.9% versus 18.8%; adjusted OR, 4.34; [95% CI 0.34–54.83]; P=0.25), were not significantly different. 94.7% of patients treated with EVT achieved successful reperfusion (modified thrombolysis in cerebral infarction 2b–3). Conclusion In routine clinical practice, EVT beyond 24 hours from LKW appears safe and feasible, when performed in patients with acute ischemic stroke who were deemed eligible for EVT by noncontrast CT /CT angiography alone. A large collaborative randomized trial assessing the efficacy of EVT beyond 24 hours is warranted. Our findings provide a basis for the sample size estimate for an adequately powered trial.

Background Patients with acute ischemic stroke onset during hospital admission often have concurrent illnesses, increased underlying comorbidities and are often associated with a delayed recognition of stroke onset, compared with patients with stroke onset in the community (community‐onset stroke [COS]). Endovascular thrombectomy (EVT) for large‐vessel occlusion in acute ischemic stroke has been proven to be effective, though the safety and feasibility of EVT among patients with in‐hospital stroke (IHS) onset remains undetermined. We aim to compare the workflow and clinical outcomes for patients undergoing EVT following IHS onset and COS. Methods Using data from a national stroke registry, we used propensity score‐matched individual‐level data of patients who underwent EVT, following IHS and COS, between October 2015 and March 2020. Univariate analysis was performed to assess the procedural, functional, and safety outcomes. Results We included 4353 patients (COS, 4104 [249 after propensity score matching]; IHS, 249 [249 after propensity score matching]). Compared with COS, patients with IHS had similar modified Rankin Scale on discharge (odds ratio [OR], 0.98 [95% CI, 0.72–1.34]; P=0.96) and at 6 months (OR, 1.25 [95% CI, 0.71–2.24]; P=0.48). No significant difference in achieving good functional outcome (modified Rankin Scale ≤ 2 at discharge; 31.3% [IHS] versus 29.3% [COS]; OR,=1.10 [95% CI 0.74–1.60]; P=0.61), successful reperfusion (modified Thrombolysis in Cerebral Infarction score of 2b–3), P=0.82; or safety outcomes of symptomatic intracranial hemorrhage (P=0.64) and in‐hospital mortality (P=0.26) were demonstrated. Shorter time interval from stroke onset to imaging in the IHS group (IHS, 80±88 versus COS, 216±292 minutes) was observed. The imaging‐to‐arterial‐puncture time was not significantly different between the groups (IHS, 160±140 versus COS, 162±184 minutes; P=0.85). Conclusions EVT in patients with IHS is safe and feasible, with comparable functional and safety outcomes to patients with COS, in this national stroke registry. Continued efforts are required to improve the inpatient stroke workflow in recognizing stroke symptoms and initiating reperfusion treatment for eligible patients with IHS.

Introduction The efficacy and safety of endovascular thrombectomy (EVT) beyond 6 hours from acute ischaemic stroke (AIS) onset for patients with proximal large vessel occlusion (LVO) selected without CT perfusion or MR imaging is undetermined in routine clinical practice. Methods In this single centre study, we identified consecutive AIS patients with an ICA or M1 MCA segment occlusion who were eligible for EVT based on non‐contrast CT/CT angiography (without CT perfusion or MR imaging) using an Alberta Stroke Program Early CT Score (ASPECTS) of ≥ 6, and an NIHSS score of≥ 6, presenting beyond 6 hours from stroke onset, between January 2018 and March 2022. During the study period, EVT capacity limitations meant EVT‐eligible patients presenting out of regular working hours (between 18.00 and 08.00 on weekdays) or on weekends, consistently received best medical management (BMM). This systemic unavailability of EVT, allows a comparison of EVT and BMM in patients who meet the same inclusion criteria, in which selection based on physician‐related bias is significantly reduced. Functional outcomes (modified Rankin Scale (mRS) at 90 days), symptomatic intracranial haemorrhage (sICH) and mortality at 90 days were compared between patients receiving EVT or BMM following multivariable adjustment for age, sex, baseline stroke severity, ASPECTS, onset‐to‐neuroimaging time, IV thrombolysis, and clot location.Pre‐specified subgroup analyses were performed. Results Among 4802 AIS patients, 150 patients (3.1%) presenting beyond 6‐hours of onset were eligible for EVT: 74 (49%) treated with EVT and 76 (51%) with BMM. Compared to the BMM group, patients treated with EVT had significantly improved functional outcome (mRS) (adjusted common OR = 2.23, 95%CI 1.18‐4.22, p = 0.013), and higher rates of functional independence (mRS≤2; 39.2.% vs 9.2%; aOR = 4.73, 95%CI 1.64‐13.63, p = 0.004). No significant difference was observed between the EVT and BMM groups in the sICH (5.4% vs 2.6%, p = 0.94) or mortality (20.2% vs 47.3%, p = 0.16) rates, respectively. EVT remained effective within the 6–12 hour and >12 hour time window subgroups. No significant treatment interaction was observed in all subgroups. Conclusions In routine clinical practice, of the 3.1% of patients in our AIS population presenting after 6 hours from stroke onset who were deemed eligible for EVT by NCCT/CTA alone, those treated with EVT achieved significantly improved functional outcome, compared to patients treated with BMM only. No significant differences were noted between the two groups with respect to sICH and mortality. While confirmatory randomised trials are awaited, these findings suggest that EVT is effective and safe when performed in AIS patients selected without CTP or MRI beyond 6 hours from stroke onset.

Background The efficacy and safety of endovascular thrombectomy (EVT) >6 hours from acute ischemic stroke (AIS) onset for patients selected without computed tomography (CT) perfusion or magnetic resonance imaging is undetermined in routine clinical practice. Methods In this single‐center study, we identified consecutive late‐presenting patients with AIS who were eligible for EVT on the basis of noncontrast CT/CT angiography (without CT perfusion or magnetic resonance imaging) using an Alberta Stroke Program Early CT Score of ≥6, >6 hours from stroke onset, between January 2018 and March 2022. During the study period, EVT capacity limitations meant EVT‐eligible patients presenting out of regular working hours, consistently received best medical management (BMM).

No significant differences were noted between the 2 groups with respect to symptomatic intracranial hemorrhage and mortality. While confirmatory randomized trials are awaited, these findings suggest that EVT is effective and safe when performed in patients with AIS selected without CT perfusion or magnetic resonance imaging >6 hours from stroke onset.

Multiple myeloma (MM) is an aggressive cancer characterised by malignancy of the plasma cells and a rising global incidence. The gold standard for optimum response is aggressive chemotherapy followed by autologous stem cell transplantation (ASCT). However, majority of the patients are above 60 years and this presents the clinician with complications such as ineligibility for ASCT, frailty, drug-induced toxicity and differential/partial response to treatment. The latter is partly driven by heterogenous genotypes of the disease in different subpopulations. In this review, we discuss emerging single cell technologies and applications in MM, population pharmacogenetics of MM, resistance to chemotherapy, genetic determinants of drug-induced toxicity, molecular signal transduction, as well as the role(s) played by epigenetics and noncoding RNAs including microRNAs (miRNAs) and long noncoding RNAs (lncRNAs) that influence the risk and severity of the disease. Taken together, our discussions further our understanding of genetic variability in ‘myelomagenesis’ and drug-induced toxicity, augment our understanding of the myeloma microenvironment at the molecular and cellular level and provide a basis for developing precision medicine strategies to combat this malignancy.

Vitamin K2-7, also known as menaquinone-7 (MK-7) is a form of vitamin K that has health-beneficial effects in osteoporosis, cardiovascular disease, inflammation, cancer, Alzheimer’s disease, diabetes and peripheral neuropathy. Compared to vitamin K1 (phylloquinone), K2-7 is absorbed more readily and is more bioavailable. Clinical studies have unequivocally demonstrated the utility of vitamin K2-7 supplementation in ameliorating peripheral neuropathy, reducing bone fracture risk and improving cardiovascular health. We examine how undercarboxylated osteocalcin (ucOC) and matrix Gla protein (ucMGP) are converted to carboxylated forms (cOC and cMGP respectively) by K2-7 acting as a cofactor, thus facilitating the deposition of calcium in bones and preventing vascular calcification. K2-7 is beneficial in managing bone loss because it upregulates osteoprotegerin which is a decoy receptor for RANK ligand (RANKL) thus inhibiting bone resorption. We also review the evidence for the health-beneficial outcomes of K2-7 in diabetes, peripheral neuropathy and Alzheimer’s disease. In addition, we discuss the K2-7-mediated suppression of growth in cancer cells via cell-cycle arrest, autophagy and apoptosis. The mechanistic basis for the disease-modulating effects of K2-7 is mediated through various signal transduction pathways such as PI3K/AKT, MAP Kinase, JAK/STAT, NF-κB, etc. Interestingly, K2-7 is also responsible for suppression of proinflammatory mediators such as IL-1α, IL-1β and TNF-α. We elucidate various genes modulated by K2-7 as well as the clinical pharmacometrics of vitamin K2-7 including K2-7-mediated pharmacokinetics/pharmacodynamics (PK/PD). Further, we discuss the current status of clinical trials on K2-7 that shed light on dosing strategies for maximum health benefits. Taken together, this is a synthetic review that delineates the health-beneficial effects of K2-7 in a clinical setting, highlights the molecular basis for these effects, elucidates the clinical pharmacokinetics of K2-7, and underscores the need for K2-7 supplementation in the global diet.

Background Pancreaticopleural fistulas are among the rarest complications of chronic pancreatitis. The main objective of the research, conducted on a total of seven patients, was to evaluate the effectiveness of early endoscopic management of pancreaticopleural fistula. Methods The diagnosis of fistula was reached when fistulous tract was demonstrated on imaging studies and/or pleural fluid amylase level was greater than 2,000 U/L. The data were retrospectively analyzed from the records. Results The prototype patient in our series was a chronic alcoholic male with median age of 45 years. Computed tomography scan was performed in all the seven patients but could diagnose leak only in four patients. Magnetic resonance cholangiopancreatography was better in the remaining three patients for diagnosing fistula. Endoscopic retrograde cholangiopancreatography was the most sensitive test that diagnosed fistula in all the seven patients. Pancreatic duct (PD) cannulation was successful and pancreatic sphincterotomy with PD stenting was performed in all the seven patients. We could avoid surgical intervention in our patients. Conclusions We advise early endoscopic treatment within 7 days of symptom onset as opposed to 3 weeks, which was proposed previously. Medical therapies should be complimentary to PD stenting.

Esophageal mucosal bridge is an elastic stretchable structure, connecting across the lumen, extending either obliquely or horizontally, more commonly seen in the mid or lower esophagus. It can be either congenital or secondary (acquired). Acquired ones are secondary to reflux esophagitis, corrosive esophageal injury, drug-induced esophagitis, radiation esophagitis, Crohn’s disease, Mallory-Weiss syndrome, malignant tumors, and infections like candidiasis, HSV, CMV, or tuberculosis. We present a case of an elderly female, who presented with progressive dysphagia for 3 months, more commonly to solids without any history of anorexia or weight loss. No history of corrosive ingestion, radiation exposure, or prior history of any surgical or endoscopic intervention was present. Upper gastrointestinal endoscopy revealed esophageal mucosal bridge at 20 and 25 cm from incisors and mucosal tag. Endoscopic resection was carried out successfully with hot biopsy forceps and needle knife after prophylactic application of hemoclips at two ends of each bridge, without any adverse event. Esophageal mucosal bridge, though rarely reported, should be kept in the differential diagnosis of patients presenting with dysphagia. Endoscopic resection with hot biopsy forceps or needle knife seems to be effective.

Neuropathic pain is a chronic pain condition seen in patients with diabetic neuropathy, cancer chemotherapy-induced neuropathy, idiopathic neuropathy as well as other diseases affecting the nervous system. Only a small percentage of people with neuropathic pain benefit from current medications. The complexity of the disease, poor identification/lack of diagnostic and prognostic markers limit current strategies for the management of neuropathic pain. Multiple genes and pathways involved in human diseases can be regulated by microRNA (miRNA) which are small non-coding RNA. Several miRNAs are found to be dysregulated in neuropathic pain. These miRNAs regulate expression of various genes associated with neuroinflammation and pain, thus, regulating neuropathic pain. Some of these key players include adenylate cyclase (Ac9), toll-like receptor 8 (Tlr8), suppressor of cytokine signaling 3 (Socs3), signal transducer and activator of transcription 3 (Stat3) and RAS p21 protein activator 1 (Rasa1). With advancements in high-throughput technology and better computational power available for research in present-day pharmacology, biomarker discovery has entered a very exciting phase. We dissect the architecture of miRNA biological networks encompassing both human and rodent microRNAs involved in the development of neuropathic pain. We delineate various microRNAs, and their targets, that may likely serve as potential biomarkers for diagnosis, prognosis, and therapeutic intervention in neuropathic pain. miRNAs mediate their effects in neuropathic pain by signal transduction through IRAK/TRAF6, TLR4/NF-κB, TXIP/NLRP3 inflammasome, MAP Kinase, TGFβ and TLR5 signaling pathways. Taken together, the elucidation of the landscape of signature miRNA regulatory networks in neuropathic pain will facilitate the discovery of novel miRNA/target biomarkers for more effective management of neuropathic pain.

Diabetes is one of the most frequently occurring metabolic disorders, affecting almost one tenth of the global population. Despite advances in antihyperglycemic therapeutics, the management of diabetes is limited due to its complexity and associated comorbidities, including diabetic neuropathy, diabetic nephropathy and diabetic retinopathy. Noncoding RNAs (ncRNAs), including microRNAs (miRNAs) and long noncoding RNAs (lncRNAs), are involved in the regulation of gene expression as well as various disease pathways in humans. Several ncRNAs are dysregulated in diabetes and are responsible for modulating the expression of various genes that contribute to the ‘symptom complex’ in diabetes. We review various miRNAs and lncRNAs implicated in diabetes and delineate ncRNA biological networks as well as key ncRNA targets in diabetes. Further, we discuss the spatial regulation of ncRNAs and their role(s) as prognostic markers in diabetes. We also shed light on the molecular mechanisms of signal transduction with diabetes-associated ncRNAs and ncRNA-mediated epigenetic events. Lastly, we summarize clinical trials on diabetes-associated ncRNAs and discuss the functional relevance of the dysregulated ncRNA interactome in diabetes. This knowledge will facilitate the identification of putative biomarkers for the therapeutic management of diabetes and its comorbidities. Taken together, the elucidation of the architecture of signature ncRNA regulatory networks in diabetes may enable the identification of novel biomarkers in the discovery pipeline for diabetes, which may lead to better management of this metabolic disorder.

Esophageal perforation is a life-threatening condition with a high mortality rate. First described around 300 years ago, management of this fatal condition has emerged from surgical to endoscopic modalities with much less morbidity and mortality when instituted early. We present this case of 55-year-old male, with double esophageal perforation by meat bone, perforating lower esophageal wall, leading to localized hydropneumothorax on right side with mild bilateral pleural effusion managed endoscopically with Over-the-Scope-Clip. Endoscopic management of esophageal perforation has been well mentioned in literature, without any mention of such management in case of double esophageal perforation. Surgery with or without endoscopy remains the main stay of management of such cases.

Background: Detecting and isolating cases of COVID-19 are amongst the key elements listed by the WHO to reduce transmission. This approach has been reported to reduce those symptomatic with COVID-19 in the population by over 90%. Testing is part of a strategy that will save lives. Testing everyone maybe ideal, but it is not practical. A risk tool based on patient demographics and clinical parameters has the potential to help identify patients most likely to test negative for SARS-CoV-2. If effective it could be used to aide clinical decision making and reduce the testing burden.Methods: At the time of this analysis, a total of 9,516 patients with symptoms suggestive of Covid-19, were assessed and tested at Mount Sinai Institutions in New York. Patient demographics, clinical parameters and test results were collected. A robust prediction pipeline was used to develop a risk tool to predict the likelihood of a positive test for Covid-19. The risk tool was analyzed in a holdout dataset from the cohort and its discriminative ability, calibration and net benefit assessed.Results: Over 48% of those tested in this cohort, had a positive result. The derived model had an AUC of 0.77, provided reliable risk prediction, and demonstrated a superior net benefit than a strategy of testing everybody. When a risk cut-off of 70% was applied, the model had a negative predictive value of 96%.Conclusion: Such a tool could be used to help aide but not replace clinical decision making and conserve vital resources needed to effectively tackle this pandemic.

In recent times, the role(s) of microRNAs (miRNAs) and long noncoding RNAs (lncRNAs) in the pathogenesis of various cancers has received great attention. Indeed, there is also a growing recognition of regulatory RNA cross-talk, i.e., lncRNA-miRNA interactions, that may modulate various events in carcinogenesis and progression to metastasis. This review summarizes current evidence in the literature of lncRNA-miRNA interactions in various cancers such as breast, liver, stomach, lung, prostate, bladder, colorectal, blood, brain, skin, kidney, cervical, laryngeal, gall bladder, and bone. Further, the potential prognostic and theragnostic clinical applications of lncRNA-miRNA interactions in cancer are discussed along with an overview of noncoding RNA (ncRNA)-based studies that were presented at the American Society of Clinical Oncology (ASCO) 2015. Interestingly, the last decade has seen tremendous innovation, as well as increase in complexity, of the cancer biological network(s) from mRNA- to miRNA- and lncRNA-based networks. Thus, biological networks devoted to understanding regulatory interactions between these ncRNAs would be the next frontier in better elucidating the contributions of lncRNA-miRNA interactions in cancer. Herein, a cancer biological network of lncRNA-miRNA interactions is presented wherein “edges” connect interacting lncRNA-miRNA pairs, with each ncRNA serving as a discrete “node” of the network. In conclusion, the untapped potential of lncRNA-miRNA interactions in terms of its diagnostic, prognostic and therapeutic potential as targets for clinically actionable intervention as well as biomarker validation in discovery pipelines remains to be explored. Future research will likely harness this potential so as to take us closer to the goal of “precision” and “personalized medicine” which is tailor-made to the unique needs of each cancer patient, and is clearly the way forward going into the future.

A 12-year-old ASA I female patient underwent correction of posterior scoliosis of dorsolumbar spine under total intravenous anesthesia using a combination of remifentanil and propofol. Induced hypotension was maintained between 55 and 65 mmHg. Intraoperatively, patient received a single injection of 1.0 g paracetamol. Surgery lasted 6 h and 40 min and was essentially uneventful. A follow-up investigation in the intensive care unit 6 h after the surgery revealed alanine transaminase levels of 547 I/U. This increased to 924 I/U on the 2 nd postoperative day after the patient received 500 mg per-rectal paracetamol. Stopping administration of paracetamol restored alanine transaminase level to normal without needing N-acetylcysteine.

Background: Observational studies have demonstrated improved outcomes with the adjunctive use of balloon guide catheters (BGC) during endovascular thrombectomy (EVT) for anterior circulation acute ischaemic stroke (AIS). However, the lack of high-level evidence and global practice heterogeneity justifies a randomised controlled trial (RCT) to investigate the effect of transient proximal blood flow arrest on the procedural and clinical outcomes of patients with AIS following EVT. Hypothesis: Proximal blood flow arrest in the cervical internal carotid artery during EVT for proximal large vessel occlusion is superior to no flow arrest in achieving complete vessel recanalisation. Methods: ProFATE is an investigator-initiated, pragmatic, multicentre RCT with blinding of participants and outcome assessment. An estimated 124 participants with an anterior circulation AIS due to large vessel occlusion, an NIHSS of ⩾2, ASPECTS ⩾ 5 and eligible for EVT using a first-line combined technique (contact aspiration and stent retriever) or contact aspiration only will be randomised (1:1) to receive BGC balloon inflation or no inflation during EVT. Outcomes: The primary outcome is the proportion of patients achieving near-complete/complete vessel recanalisation (eTICI 2c-3) at the end of the EVT procedure. Secondary outcomes include the functional outcome (modified Rankin Scale at 90 days), new or distal vascular territory clot embolisation rate, near-complete/complete recanalisation after the first pass, symptomatic intracranial haemorrhage, procedure-related complications and death at 90 days. Discussion: This is the first RCT to investigate the effect of proximal blood flow arrest during EVT using a BGC on the procedural and clinical outcomes of patients with AIS due to large vessel occlusion.

To find an association between genomic features of connective tissue and pejorative clinical outcomes on radical prostatectomy specimens. We performed a retrospective analysis of patients who underwent radical prostatectomy and underwent a Decipher transcriptomic test for localized prostate cancer in our institution (n = 695). The expression results of selected connective tissue genes were analyzed after multiple t tests, revealing significant differences in the transcriptomic expression (over- or under-expression). We investigated the association between transcript results and clinical features such as extra-capsular extension (ECE), clinically significant cancer, lymph node (LN) invasion and early biochemical recurrence (eBCR), defined as earlier than 3 years after surgery). The Cancer Genome Atlas (TCGA) was used to evaluate the prognostic role of genes on progression-free survival (PFS) and overall survival (OS). Out of 528 patients, we found that 189 had ECE and 27 had LN invasion. The Decipher score was higher in patients with ECE, LN invasion, and eBCR. Our gene selection microarray analysis showed an overexpression in both ECE and LN invasion, and in clinically significant cancer for COL1A1, COL1A2, COL3A1, LUM, VCAN, FN1, AEBP1, ASPN, TIMP1, TIMP3, BGN, and underexpression in FMOD and FLNA. In the TCGA population, overexpression of these genes was correlated with worse PFS. Significant co-occurrence of these genes was observed. When presenting overexpression of our gene selection, the 5-year PFS rate was 53% vs. 68% (p = 0.0315). Transcriptomic overexpression of connective tissue genes correlated to worse clinical features, such as ECE, clinically significant cancer and BCR, identifying the potential prognostic value of the gene signature of the connective tissue in prostate cancer. TCGAp cohort analysis showed a worse PFS in case of overexpression of the connective tissue genes.

BackgroundThere is a paucity of data on anesthesia-related outcomes for endovascular treatment (EVT) in the extended window (>6 hours from ischemic stroke onset). We compared functional and safety outcomes between local anesthesia (LA) without sedation, conscious sedation (CS) and general anesthesia (GA).MethodsPatients who underwent EVT in the early (ResultsA total of 4337 patients were included, 3193 in the early window (1135 LA, 446 CS, 1612 GA) and 1144 in the extended window (357 LA, 134 CS, 653 GA). Compared with GA, patients treated under LA alone had increased odds of an improved modified Rankin Scale (mRS) score at discharge (early: adjusted common (ac) OR=1.50, 95% CI 1.29 to 1.74, p=0.001; extended: acOR=1.29, 95% CI 1.01 to 1.66, p=0.043). Similar mRS scores at discharge were found in the LA and CS cohorts in the early and extended windows (p=0.21). Compared with CS, use of GA was associated with a worse mRS score at discharge in the early window (acOR=0.73, 95% CI 0.45 to 0.96, p=0.017) but not in the extended window (p=0.55). There were no significant differences in the rates of symptomatic intracranial hemorrhage or in-hospital mortality across the anesthesia modalities in the extended window.ConclusionLA without sedation during EVT was associated with improved functional outcomes compared with GA, but not CS, within and beyond 6 hours from stroke onset. Prospective studies assessing anesthesia-related outcomes in the extended time window are warranted.

BackgroundThe safety and functional outcome of endovascular thrombectomy (EVT) in the very late (VL; >24 hours) time window from ischemic stroke onset remains undetermined.MethodsUsing data from a national stroke registry, we used propensity score matched (PSM) individual level data of patients who underwent EVT, selected with CT perfusion or non-contrast CT/CT angiography, between October 2015 and March 2020. Functional and safety outcomes were assessed in both late (6–24 hours) and VL time windows. Subgroup analysis was performed of imaging selection modality in the VL time window.ResultsWe included 1150 patients (late window: 1046 (208 after PSM); VL window: 104 (104 after PSM)). Compared with EVT treatment initiation between 6 and 24 hours, patients treated in the VL window had similar modified Rankin Scale (mRS) scores at discharge (ordinal shift; common OR=1.08, 95% CI 0.69 to 1.47, p=0.70). No significant differences in achieving good functional outcome (mRS ≤2 at discharge; 28.8% (VL) vs 29.3% (late), OR=0.97, 95% CI 0.58 to 1.64, p=0.93), successful reperfusion (modified Thrombolysis in Cerebral Infarction score of 2b–3) (p=0.77), or safety outcomes of symptomatic intracranial hemorrhage (p=0.43) and inhospital mortality (p=0.23) were demonstrated. In the VL window, there was no significant difference in functional outcome among patients selected with perfusion versus those selected without perfusion imaging (common OR=1.38, 95% CI 0.81 to 1.76, p=0.18).ConclusionIn this real world study, EVT beyond 24 hours from stroke onset or last known well appeared to be feasible, with comparable safety and functional outcomes to EVT initiation between 6 and 24 hours. Randomized trials assessing the efficacy of EVT in the VL window are warranted, but may only be feasible with a large international collaborative approach.

- Abstract
Cancer chemopreventive agent sulforaphane (SFN) and dibenzoylmethane (DBM) showed antitumorigenesis effects in several rodent carcinogenesis models. In this study, we investigated the cancer chemopreventive effects and the underlying molecular mechanisms of dietary administration of SFN and DBM alone or in combination in the ApcMin/+ mice model. Male ApcMin/+ mice (12 per group) at age of 5 weeks were given control AIN-76A diet, diets containing 600 ppm SFN and 1.0% DBM, or a combination of 300 ppm SFN and 0.5% DBM for 10 weeks. Mice were then sacrificed, and tumor numbers and size were examined. Microarray analysis, Western blotting, ELISA, and immunohistochemical staining were done to investigate the underlying molecular mechanisms of cancer chemopreventive effects of SFN and DBM. Dietary administrations of SFN and DBM alone or in combination significantly inhibited the development of intestinal adenomas by 48% (P = 0.002), 50% (P = 0.001), and 57% (P < 0.001), respectively. Dietary administration of 600 ppm SFN and 1.0% DBM also reduced colon tumor numbers by 80% (P = 0.016) and 60% (P = 0.103), respectively, whereas the combination of SFN and DBM treatment blocked the colon tumor development (P = 0.002). Both SFN and DBM treatments resulted in decreased levels of prostaglandin E2 or leukotriene B4 in intestinal polyps or apparently normal mucosa. Treatments also led to the inhibition of cell survival and growth-related signaling pathways (such as Akt and extracellular signal-regulated kinase) or biomarkers (such as cyclooxygenase-2, proliferating cell nuclear antigen, cleaved caspases, cyclin D1, and p21). In conclusion, our results showed that both SFN and DBM alone as well as their combination are potent natural dietary compounds for chemoprevention of gastrointestinal cancers.

- Abstract
Proline-, glutamic acid–, leucine-rich protein 1 (PELP1), a novel nuclear receptor coactivator, and its expression is deregulated in hormone-dependent cancers, including those of the breast, endometrium, and ovary. PELP1 interacts with estrogen receptor and modulates its genomic and nongenomic functions. In this study, we examined whether PELP1 functions as an oncogene. The overexpression of PELP1 in fibroblasts and epithelial model cells resulted in cellular transformation. PELP1 also enhanced the transformation potential of c-Src kinase in focus formation assays, and PELP1 overexpression potentiated estradiol-mediated cell migratory potential and anchorage-independent growth. Using PELP1-small interfering RNA, we provided evidence that endogenous PELP1 plays an essential role in E2-mediated anchorage-independent growth, cell migration, and cytoskeletal changes. When compared with control vector transfectants, breast cancer cells stably overexpressing PELP1 showed a rapid tumor growth in xenograft studies. Immunohistochemical analysis of PELP1 expression using a tumor progression array of 252 breast carcinomas and normal breast tissue specimens revealed that PELP1 expression is deregulated to a greater degree in higher grade node-positive invasive tumors than in normal breast tissue or ductal carcinoma in situ. Our data suggest that PELP1 is a potential oncogene, that its expression is deregulated during cancer progression, and that PELP1 may play a role in oncogenesis. [Cancer Res 2007;67(11):5505–12]

Methods This was single-center, open-label, randomized trial. Patients who were undergoing ERCP and who were at high risk for the development of PEP were selected for the study. Patients were randomized into 3 treatment groups: diclofenac suppository group, RL group, and a combination group. Results Eight of 57 patients (14.03%) in the diclofenac group, 9 of 57 patients (15.78%) in the RL group, and 6 of 57 patients (10.52%) in the combination group developed PEP. The incidence of PEP between the three groups was not statistically significant (P = 0.70). Serum amylase level of >252 U/L had 91.3% sensitivity and 92.6% specificity for the diagnosis of PEP. Conclusions Post-ERCP pancreatitis is usually mild to moderate 95% times. Female sex, age younger than 50 years, a benign indication of ERCP, and low bilirubin levels have higher chances of PEP. A combination of rectal diclofenac and hydration with RL does not offer better protection for PEP, as compared with individual prophylaxis.

Several studies have reported the health-beneficial effects of dietary phytochemicals, namely polyphenols, to prevent various diseases, including cancer. Polyphenols, like (-)-epigallocatechin-3-gallate (EGCG) from green tea, curcumin from turmeric, and ellagic acid from pomegranate are known to act by modulating antioxidant, anti-inflammatory and apoptotic signal transduction pathways in the tumor milieu. The evolving literature underscores the role of epigenetic regulation of genes associated with cancer by these polyphenols, primarily via non-coding RNAs (ncRNAs), such as microRNAs (miRNA) and long noncoding RNA (lncRNA). However, there is little clarity on the exact role(s) played by these ncRNAs and their interactions with other ncRNAs, or with their protein targets, in response to modulation by these dietary polyphenols. Here, we review ncRNA interactions and functional networks of the complex ncRNA interactome with their targets in preclinical studies along with the role of epigenetics as well as key aspects of pharmacokinetics and phytochemistry of dietary polyphenols. We also summarize the current state of clinical trials with these dietary polyphenols. Taken together, this synthetic review provides insights into the molecular aspects underlying the anticancer chemopreventive effects of dietary polyphenols as well as summarizes data on novel biomarkers modulated by these polyphenols for preventive or therapeutic purposes in various types of cancer.

Background Little is known about the safety of off-label use of an 8Fr Angio-Seal VIP for large-bore arteriotomies in patients treated with mechanical thrombectomy (MT) and intravenous thrombolysis (IVT) for acute ischaemic stroke (AIS). We aimed to identify differences in the groin complication rate using an 8Fr Angio-Seal VIP for common femoral arteriotomy closures following the use of 8Fr and 9Fr sheaths. Methods All AIS patients who underwent MT at our tertiary neuroscience unit between January 2018 and March 2020 were retrospectively reviewed. Results 161 patients were included in the study, of whom 56 and 105 patients underwent an arteriotomy using an 8Fr sheath (36 of them receiving IVT) and a 9Fr sheath (57 of them receiving IVT). Overall, 17 groin complications were identified (10.5%) in 5 patients (8.9%) who had had 8Fr sheaths inserted and 12 patients (11.4%) who had had 9Fr sheaths inserted. Major complications were identified in only 2 patients (1.2%), one patient in each of the 8Fr and 9Fr cohorts suffering a pseudoaneurysm requiring intervention. No retroperitoneal haematoma, infection, acute limb ischaemia or ipsilateral DVT was identified. No significant difference in groin complications was observed between the 8Fr and 9Fr femoral arteriotomy cohorts or between the MT patients that did or did not receive adjunctive IVT. Conclusion In the setting of MT with IVT, off-label use of an 8Fr Angio-Seal VIP for closure of a femoral arteriotomy following use of a 9Fr sheath has a similar safety profile to the licensed use of an 8Fr Angio-Seal VIP for closure of a femoral arteriotomy following use of an 8Fr sheath or smaller.

An important goal in management of acute pancreatitis (AP) is early prediction and recognition of disease severity. Various predictive scoring systems are in clinical use with their own limitations and there is always a quest for simple, practical, quantifiable, dynamic and readily available markers for predicting disease severity and outcome. Complete hemogram is routinely ordered in all patients with AP. In recent years red cell distribution width (RDW), neutrophil-lymphocyte ratio (NLR), lymphocyte-monocyte ratio (LMR) and platelet lymphocyte ratio (PLR) have been found to be independent predictors of prognosis in various benign and malignant conditions. This prospective study evaluated complete hemogram based markers in AP. Complete hemogram analysis was done and NLR, LMR, PLR values were calculated. Development of organ failure, the need for intensive care unit (ICU) admission and interventions, development of complications (local/systemic) and 100-day mortality were assessed. In this study 160 subjects of AP were included. Complete hemogram analysis was performed within 24 h after admission. C‑reactive protein, RDW, NLR, PLR and bedside index of severity in acute pancreatitis (BISAP) values were higher in severe AP than moderate AP group than mild AP group, while LMR values were decreased in the corresponding severe, moderate and mild AP groups (p

Background: The impact on clinical outcomes of patient selection using perfusion imaging for endovascular thrombectomy (EVT) in patients with acute ischemic stroke presenting beyond 6 hours from onset remains undetermined in routine clinical practice. Methods: Patients from a national stroke registry that underwent EVT selected with or without perfusion imaging (noncontrast computed tomography/computed tomography angiography) in the early ( Results: We included 4249 patients, 3203 in the early window (593 with perfusion versus 2610 without perfusion) and 1046 in the late window (378 with perfusion versus 668 without perfusion). Within the late window, patients with perfusion imaging had a shift towards better functional outcome at discharge compared with those without perfusion imaging (adjusted common odds ratio [OR], 1.45 [95% CI, 1.16–1.83]; P =0.001). There was no significant difference in functional independence (29.3% with perfusion versus 24.8% without; P =0.210) or in the safety outcome measures of symptomatic intracerebral hemorrhage ( P =0.53) and in-hospital mortality (10.6% with perfusion versus 14.3% without; P =0.053). In the early time window, patients with perfusion imaging had significantly improved odds of functional outcome (adjusted common OR, 1.51 [95% CI, 1.28–1.78]; P =0.0001) and functional independence (41.6% versus 33.6%, adjusted OR, 1.31 [95% CI, 1.08–1.59]; P =0.006). Perfusion imaging was associated with lower odds of futile recanalization in both time windows (late: adjusted OR, 0.70 [95% CI, 0.50–0.97]; P =0.034; early: adjusted OR, 0.80 [95% CI, 0.65–0.99]; P =0.047). Conclusions: In this real-world study, acquisition of perfusion imaging for EVT was associated with improvement in functional disability in the early and late time windows compared with nonperfusion neuroimaging. These indirect comparisons should be interpreted with caution while awaiting confirmatory data from prospective randomized trials.

Background Pancreaticopleural fistulas are among the rarest complications of chronic pancreatitis. The main objective of the research, conducted on a total of seven patients, was to evaluate the effectiveness of early endoscopic management of pancreaticopleural fistula. Methods The diagnosis of fistula was reached when fistulous tract was demonstrated on imaging studies and/or pleural fluid amylase level was greater than 2,000 U/L. The data were retrospectively analyzed from the records. Results The prototype patient in our series was a chronic alcoholic male with median age of 45 years. Computed tomography scan was performed in all the seven patients but could diagnose leak only in four patients. Magnetic resonance cholangiopancreatography was better in the remaining three patients for diagnosing fistula. Endoscopic retrograde cholangiopancreatography was the most sensitive test that diagnosed fistula in all the seven patients. Pancreatic duct (PD) cannulation was successful and pancreatic sphincterotomy with PD stenting was performed in all the seven patients. We could avoid surgical intervention in our patients. Conclusions We advise early endoscopic treatment within 7 days of symptom onset as opposed to 3 weeks, which was proposed previously. Medical therapies should be complimentary to PD stenting.

Background: Temozolomide is used as frontline chemotherapy in the management of glioblastoma multiforme (GBM); however, its clinical utility is limited by the occurrence of significant resistance, majorly caused due to direct DNA repair. O6- methylguanine-DNA-methyltransferase (MGMT), a DNA repair protein, mediates this direct repair pathway and reverses the activity of temozolomide. Methods: We characterize and underscore the functional relevance and molecular aspects of MGMT in the development of sensitivity/resistance to temozolomide treatment. We review early translational, as well as clinical, evidence for the role of MGMT in mediating temozolomide resistance in vitro in cell lines, in vivo in small animals as well as in GBM patients. Results: Various approaches have been delineated to mitigate MGMT-induced temozolomide resistance. The most promising means in discovery biology appears to be the co-administration of MGMT inhibitors such as O6 benzyl guanine or lomeguatrib. Surprisingly, the validation of these pharmacologic inhibitors to assess the reversal of chemoresistance by appropriately designed safety and efficacy trials in combination with temozolomide is yet to be demonstrated. Conclusions: Taken together, given the regulation of temozolomide resistance by MGMT, intermediate and late discovery groups may focus their efforts on pharmacologic inhibition of MGMT, singly or in combination with radiotherapy or immunotherapy, to combat temozolomide resistance in GBM patients. In addition, one may speculate that the combined clinical use of temozolomide with a drug regulator-approved MGMT inhibitor as well as an immune checkpoint inhibitor such as nivolumab may prove beneficial. Future studies may also investigate any inter-ethnic variability in population pharmacogenetics of MGMT and pharmacometric approaches to optimize cancer precision medicine.

The health-beneficial effects of various phytochemicals and nutraceuticals have been known historically especially in ancient systems of medicine such as Indian Ayurvedic Medicine, Traditional Chinese Medicine and African Traditional Medicine for combating cancer, inflammation, cardiovascular and metabolic diseases. Moringa oleifera Lam., commonly known as the ‘drumstick’ tree, is a cruciferous tree belonging to the Moringaceae family, which shows antiinflammatory, anticancer and nutraceutical properties. The isothiocyanates present in the leaves or leaf extracts have been shown to modulate critical signal transduction pathways involved in cancer. The leaves are also widely used for their nutraceutical benefits in building body fitness and improving overall health. We discuss the phytochemistry, molecular mechanisms for anticancer chemopreventive activity as well as anticancer nanotheranostic formulations of Moringa. Relatively few preclinical and clinical studies have been conducted so far to scientifically establish the anticancer potential of Moringa and these are discussed here. Importantly, the available literature is encouraging and supports the use of Moringa in cancer chemoprevention. Future work needs to focus on appropriately designed clinical trials in cancer patients to systematically evaluate the clinical anticancer potential of Moringa. Taken together, scientific investigation of Moringa isothiocyanates alone, or Moringa leaf powder as a nutraceutical and/or functional food, can open new avenues in discovery research for translating the anticancer benefits of Moringa from bench-to-bedside for cancer prevention.

Esophageal mucosal bridge is an elastic stretchable structure, connecting across the lumen, extending either obliquely or horizontally, more commonly seen in the mid or lower esophagus. It can be either congenital or secondary (acquired). Acquired ones are secondary to reflux esophagitis, corrosive esophageal injury, drug-induced esophagitis, radiation esophagitis, Crohn’s disease, Mallory-Weiss syndrome, malignant tumors, and infections like candidiasis, HSV, CMV, or tuberculosis. We present a case of an elderly female, who presented with progressive dysphagia for 3 months, more commonly to solids without any history of anorexia or weight loss. No history of corrosive ingestion, radiation exposure, or prior history of any surgical or endoscopic intervention was present. Upper gastrointestinal endoscopy revealed esophageal mucosal bridge at 20 and 25 cm from incisors and mucosal tag. Endoscopic resection was carried out successfully with hot biopsy forceps and needle knife after prophylactic application of hemoclips at two ends of each bridge, without any adverse event. Esophageal mucosal bridge, though rarely reported, should be kept in the differential diagnosis of patients presenting with dysphagia. Endoscopic resection with hot biopsy forceps or needle knife seems to be effective.

Aim of the study: Decompensated hepatitis C virus (HCV) cirrhosis is a difficult to treat cohort, and there is no gold standard predictor of response to direct-acting antiviral (DAA) therapy. We conducted this study to look for factors responsible for improvement in post-therapy status, i.e. attainment of Child-Turcotte-Pugh (CTP) class A from B or C, and devise a new model to predict post-therapy response. Material and methods: Prospective analysis of data from decompensated HCV cirrhotics was done and association of each parameter with patient outcomes at 36 weeks after treatment was assessed. Results 34 patients (54.8%) attained CTP class A after treatment. Factors that were independently associated with disease outcome included albumin (odds ratio [OR] = 4.84, 95% confidence interval [CI]: 1.43-20.15, p = 0.018), alanine transaminase (ALT) (OR = 1.02, 95% CI: 1-1.04, p = 0.049), bilirubin (OR = 0.41, 95% CI: 0.2-0.75, p = 0.007) and estimated glomerular filtration rate (eGFR) (OR = 1.03, 95% CI: 1.0-1.06, p = 0.045). On multivariate analysis, bilirubin was significantly associated with treatment outcome (OR = 0.28, 95% CI: 0.1-0.64, p = 0.006). A composite model was devised using demographic, biochemical, and clinical features, which has sensitivity, specificity, positive predictive value, negative predictive value and accuracy of 67.86%, 79.41%, 73.08%, 75%, and 73.63% respectively in predicting response to therapy. Only 7.6% of patients with a Model for End-Stage Liver Disease (MELD) score > 15 and none of the patients with CTP class C met the primary end-point of our study. Conclusions 55% of our cohort met the primary end-point at 36 weeks. Patients with CTP class C and a MELD score > 15 should be referred for liver transplantation followed by DAA therapy. Our model was good at predicting improvement in post-therapy liver function.

Background Splanchnic venous system thrombosis is a well recognized local vascular complication of acute pancreatitis (AP). It may involve thrombosis of splenic vein (SplV), portal vein (PV) and superior mesenteric vein (SMV), either separately or in combinations, and often detected incidentally, indeed some cases present with upper gastrointestinal bleed, bowel ischemia and hepatic decompensation. Incidence is variable depending on study subjects and diagnostic modalities. Pathogenesis is multifactorial centered on local and systemic inflammation. Management involves treatment of underlying AP and its complications. Universal use of anticoagulation may lead to increased risk of bleeding due to frequent need of interventions (radiologic/endoscopic/surgical). Literature on anticoagulation in setting of AP is sparse and at present there is no consensus guideline on it. Current article details our experience on splanchnic venous thrombosis (SVT) in AP in a well defined cohort of patients at a tertiary care center. Methods Hospitalized patients with AP from January 2018 to December 2018 were included in the study. Detailed information on demographic, clinical, laboratory, radiologic features, and indication of anticoagulation use were collected prospectively during the index admission. Outcome variables were analyzed at the end of 6 months. Results Twenty four out of 105 (22.85%) patients with AP develop SVT. Etiology of AP was alcohol use in 21/24 (87.5%) subjects. Most common vessel involved was isolated SplV in 11/24 (45.8%) patients followed by SplV along with PV and SMV 9/24 (37.50%, P < 0.001). Bowel ischemia 4/12 (33.3%), hepatic decompensation 3/12 (25%), triple vessel involvement 4/12 (33.3%) and pulmonary embolism 1/12 (8.3%) were reasons for anticoagulation. There was no statistical difference with respect to development of varices, collateral formation, recanalization, bleeding and mortality with use of anticoagulation (P > 0.05 with respect to all above variables). Conclusions SVT is commonly seen in alcohol-induced AP. Anticoagulation does not affect outcomes of SVT. Subset of patients may benefit with anticoagulation.
