RESUMO
BACKGROUND & AIMS: Noninvasive variceal risk stratification systems have not been validated in patients with hepatocellular carcinoma (HCC), which presents logistical barriers for patients in the setting of systemic HCC therapy. We aimed to develop and validate a noninvasive algorithm for the prediction of varices in patients with unresectable HCC. METHODS: We performed a retrospective cohort study in 21 centers in the United States including adult patients with unresectable HCC and Child-Pugh A5-B7 cirrhosis diagnosed between 2007 and 2019. We included patients who completed an esophagogastroduodonoscopy (EGD) within 12 months of index imaging but before HCC treatment. We divided the cohort into a 70:30 training set and validation set, with the goal of maximizing negative predictive value (NPV) to avoid EGD in low-risk patients. RESULTS: We included 707 patients (median age, 64.6 years; 80.6% male; 74.0% White). Median time from HCC diagnosis to EGD was 47 (interquartile range, 114) days, with 25.0% of patients having high-risk varices. A model using clinical variables alone achieved an NPV of 86.3% in the validation cohort, whereas a model integrating clinical and imaging variables had an NPV 97.4% in validation. The clinical and imaging model would avoid EGDs in more than half of low-risk patients while misclassifying 7.7% of high-risk patients. CONCLUSIONS: A model incorporating clinical and imaging data can accurately predict the absence of high-risk varices in patients with HCC and avoid EGD in many low-risk patients before the initiation of systemic therapy, thus expediting their care and avoiding treatment delays.
RESUMO
INTRODUCTION: Esophageal Stents are used to maintain esophageal lumen patency in esophageal strictures caused by intrinsic and/or extrinsic malignancies and the occlusion of concomitant esophageal fistulas. While data on the efficacy and safety of esophageal stents exist, comprehensive evaluation of adverse events is limited. The aim of this study is to investigate the reported adverse events and device failures associated with esophageal self-expandable metal stents (SEMS) using the FDA's Manufacturer and User Facility Device Experience (MAUDE) database. METHODS: Post-marketing surveillance data for the esophageal SEMSs were analyzed using the FDA's MAUDE database from January 2014 to December 10, 2023. The outcomes of interest were patient-related adverse events and device failures. Statistical analysis was performed using Microsoft Excel 2010 and SPSS. Pooled numbers and percentages were calculated for each adverse event. Continuous variables underwent analysis using a two-tailed student t test, and significance was set to p ≤ 0.05. RESULTS: During the study period, 548 MAUDE reports revealed 873 device failures and 186 patient-related adverse events. The most common device issues were stent activation, positioning, or separation problems (4 n = 403; 46.2%), followed by device detachment or migration (n = 109, 12.5%), and material problems (n = 93, 10.7%). Patient complications included dysphagia/odynophagia (10%), perforation, pain, and bleeding (each 7.6%). The most common device failures in over-the-wire (OTW) stents and through-the-scope (TTS) stents were activation, positioning, or separation problems (TTS: n = 183, 52.6% vs OTW: n = 220, 41.9%). Compared to OTW stents, TTS stents had higher migration and breakage (13.5% vs. 11.8%, p = 0.24), and (9.2% vs. 6.7%, p = 0.08) respectively, while OTW stents had more challenges with stent advancement or removal (5.1% vs. 0.3%, p < 0.001 and 4.6% vs 3.4%, p = 0.19, respectively) and material problems (14.7% vs. 4.6%, p < 0.001). Activation, positioning, and separation problems were the most frequent device failures in fully covered (FC) and partially covered (PC) stents (FC: n = 62, 32.8%, PC: n = 168, 43.5%). FC stents had higher migration rates (20.6% vs 9.8%, p < 0.001), while PC stents exhibited more material problems (17.4% vs. 5.8%, p < 0.001) and difficulties with advancing the stents (6.7% vs. 0%, p < 0.001). CONCLUSION: Our examination showed a prevalence of reported device complications associated with stent activation, positioning, and separation problems. Dysphagia or odynophagia emerged as the most frequently reported patient complication. Furthermore, our analysis, provides insights into TTS vs. OTW and FC vs. PC esophageal SEMSs, enabling endoscopists and manufacturers to better understand adverse events and potentially optimize device design for future iterations.

BACKGROUND: Surgical guides have been proposed in an attempt to reach more predictable outcomes for esthetic crown lengthening. The objective of the present study was to evaluate the effectiveness of esthetic crown lengthening using 3D-printed surgical guides in the management of excessive gingival display due to altered passive eruption type 1B. MATERIALS AND METHODS: Sixteen patients diagnosed with altered passive eruption type 1B, were divided into two groups. In the control group, the procedure was carried out conventionally, and in the study group, a dual surgical guide was used. The parameters of wound healing (swelling, color, probing depth, bleeding index, and plaque index), pain scores, gingival margin stability, and operating time were assessed at 1 week, 2 weeks, 3 months, and 6 months postoperatively. RESULTS: There was no statistically significant difference in terms of wound healing, pain scores, and gingival margin stability between both groups at different time intervals (P = 1), however, there was a statistical difference between both groups in terms of operating time with the study group being significantly lower (P < 0.001). CONCLUSION: Digitally assisted esthetic crown lengthening helps shorten the operating time and reduces the possibility of human errors during the measurements. This will be useful in helping practitioners achieve better results. PRACTICAL IMPLICATIONS: The conventional method remains to be the gold standard. However, shorter operating time and lower margins for errors will help reduce costs as the chair side time is reduced as well as the possibility for a second surgery is lower. This will improve patient satisfaction as well.

OBJECTIVES: To evaluate the frequency and pattern of pulmonary vascular abnormalities in the year following COVID-19. METHODS: The study population included 79 patients remaining symptomatic more than 6 months after hospitalization for SARS-CoV-2 pneumonia who had been evaluated with dual-energy CT angiography. RESULTS: Morphologic images showed CT features of (a) acute (2/79; 2.5%) and focal chronic (4/79; 5%) PE; and (b) residual post COVID-19 lung infiltration (67/79; 85%). Lung perfusion was abnormal in 69 patients (87.4%). Perfusion abnormalities included (a) perfusion defects of 3 types: patchy defects (n = 60; 76%); areas of non-systematized hypoperfusion (n = 27; 34.2%); and/or PE-type defects (n = 14; 17.7%) seen with (2/14) and without (12/14) endoluminal filling defects; and (b) areas of increased perfusion in 59 patients (74.9%), superimposed on ground-glass opacities (58/59) and vascular tree-in-bud (5/59). PFTs were available in 10 patients with normal perfusion and in 55 patients with abnormal perfusion. The mean values of functional variables did not differ between the two subgroups with a trend toward lower DLCO in patients with abnormal perfusion (74.8 ± 16.7% vs 85.0 ± 8.1). CONCLUSION: Delayed follow-up showed CT features of acute and chronic PE but also two types of perfusion abnormalities suggestive of persistent hypercoagulability as well as unresolved/sequelae of microangiopathy. CLINICAL RELEVANCE STATEMENT: Despite dramatic resolution of lung abnormalities seen during the acute phase of the disease, acute pulmonary embolism and alterations at the level of lung microcirculation can be identified in patients remaining symptomatic in the year following COVID-19. KEY POINTS: ⢠This study demonstrates newly developed proximal acute PE/thrombosis in the year following SARS-CoV-2 pneumonia. ⢠Dual-energy CT lung perfusion identified perfusion defects and areas of increased iodine uptake abnormalities, suggestive of unresolved damage to lung microcirculation. ⢠This study suggests a complementarity between HRCT and spectral imaging for proper understanding of post COVID-19 lung sequelae.

BACKGROUND AND OBJECTIVE: Endoscopic polypectomy is an excellent tool for colon cancer prevention. With the innovation of novel resection techniques, the best method is still being investigated. Hence, we aim to evaluate the efficacy and safety of cold snare polypectomy (CSP) versus hot snare polypectomy (HSP) for colorectal polyp resection. METHODS: A systematic review and meta-analysis synthesizing evidence from randomized controlled trials retrieved from PubMed, EMBASE, WOS, SCOPUS, and CENTRAL until July 16, 2022. We pooled dichotomous outcomes using risk ratio (RR) with the corresponding CI. This review's protocol was prospectively registered in PROSPERO with ID: CRD42022347496. RESULTS: We included 18 randomized controlled trials with a total of 4317 patients and 7509 polyps. Pooled RR favored HSP regarding the complete resection rate (RR: 0.96 with 95% CI: 0.95, 1, P = 0.03) and local recurrence incidence (RR: 5.74 with 95% CI: 1.27, 25.8, P = 0.02). Pooled RR favored CSP regarding the colonoscopy time (mean difference: -6.50 with 95% CI: -7.55, -5.44, P = 0.00001) and polypectomy time (mean difference: -57.36 with 95% CI: -81.74, -32.98, P = 0.00001). There was no difference regarding the incidence of immediate bleeding ( P = 0.06) and perforation ( P = 0.39); however, HSP was associated with more incidence of delayed bleeding ( P = 0.01), abdominal pain ( P = 0.007), and postresection syndrome ( P = 0.02). DISCUSSION: HSP is associated with a higher complete resection and lower recurrence rates; however, HSP is also associated with a higher incidence of adverse events. Therefore, improving the complete resection rate with CSP still warrants more innovation, giving the technique safety and shorter procedure duration.

BACKGROUND: A recent randomized phase II trial evaluated stereotactic ablative radiotherapy (SABR) in a group of patients with a small burden of oligometastatic disease (mostly with 1-3 metastatic lesions), and found that SABR was associated with a significant improvement in progression-free survival and a trend to an overall survival benefit, supporting progression to phase III randomized trials. METHODS: Two hundred and ninety-seven patients will be randomized in a 1:2 ratio between the control arm (consisting of standard of care [SOC] palliative-intent treatments), and the SABR arm (consisting of SOC treatment + SABR to all sites of known disease). Randomization will be stratified by two factors: histology (prostate, breast, or renal vs. all others), and disease-free interval (defined as time from diagnosis of primary tumor until first detection of the metastases being treated on this trial; divided as ≤2 vs. > 2 years). The primary endpoint is overall survival, and secondary endpoints include progression-free survival, cost effectiveness, time to development of new metastatic lesions, quality of life (QoL), and toxicity. Translational endpoints include assessment of circulating tumor cells, cell-free DNA, and tumor tissue as prognostic and predictive markers, including assessment of immunological predictors of response and long-term survival. DISCUSSION: This study will provide an assessment of the impact of SABR on survival, QoL, and cost effectiveness to determine if long-term survival can be achieved for selected patients with 1-3 oligometastatic lesions. TRIAL REGISTRATION: Clinicaltrials.gov identifier: NCT03862911. Date of registration: March 5, 2019.

We have shown that a high fat diet (HFD) induces the activation of retinal NOD-like receptor protein (NLRP3)-inflammasome that is associated with enhanced expression and interaction with thioredoxin-interacting protein (TXNIP). Here, the specific contribution of TXNIP and the impact of HFD on retinal leukostasis, barrier dysfunction and microvascular degeneration were investigated. Wild-type (WT) and TXNIP knockout (TKO) mice were fed with normal diet or 60% HFD for 8-18 weeks. TXNIP was overexpressed or silenced in human retinal endothelial cells (REC). At 8 weeks, HFD significantly induced retinal leukostasis and breakdown of the blood-retina barrier in WT mice, but not in TKO mice. In parallel, HFD also induced retinal expression of adhesion molecules and cleaved IL-1ß in WT mice, which were also abrogated in TKO mice. In culture, TXNIP overexpression induced NLRP3, IL-1b, and adhesion molecules expression, while TXNIP silencing inhibited them. Blocking the IL-1ß receptor significantly suppressed TXNIP-induced expression of NLRP3-inflammasome and adhesion molecules in HREC. Ex-vivo assay showed that leukocytes isolated from WT-HFD, but not from TKO-HFD, induced leukostasis and cell death. At 18 weeks, HFD triggered development of degenerated (acellular) capillaries and decreased branching density in WT but not in TKO mice. Together, HFD-induced obesity triggered early retinal leukostasis and microvascular dysfunction at least in part via TXNIP-NLRP3-inflammasome activation.

Oral cancer is a common malignancy in both men and women worldwide; this cancer is characterized by a marked propensity for invasion and spreading to local lymph nodes. On the other hand, Elaeagnus angustifolia (EA) is a medicinal plant that has been used for centuries for treating many human diseases in the Middle East. However, the effect of EA plant extract on human cancers especially oral has not been investigated yet. Thus, first we examined the outcome of EA flower extract on angiogenesis, using the chorioallantoic membrane (CAM) of the chicken embryo; we found that EA extract reduces blood vessel development of the CAM. Then, we investigated the effect of EA flower extract on selected parameters in FaDu and SCC25 oral cancer cell lines. Our results show that EA extract inhibits cell proliferation and colony formation, in addition to the initiation of S cell cycle arrest and reduction of G1/G2 phase. In parallel, EA extract provokes differentiation to an epithelial phenotype "mesenchymal-to-epithelial transition: MET" which is the opposite of "epithelial-to-mesenchymal transition, EMT": an important event in cell invasion and metastasis. Thus, EA plant extract causes a dramatic decrease in cell invasion and motility abilities of FaDu and SCC25 cancer cells in comparison with their controls. These changes are accompanied by an upregulation of E-cadherin expression. The molecular pathway analysis of the EA flower extract reveals that it can inhibit the phosphorylation of Erk1/Erk2, which could be behind the inhibition of angiogenesis, the initiation of MET event, and the overexpression of E-cadherin. Our findings indicate that EA plant extract can reduce human oral cancer progression by the inhibition of angiogenesis and cell invasion via Erk1/Erk2 signaling pathways.

AIMS/HYPOTHESIS: Obesity and hypertension, known pro-inflammatory states, are identified determinants for increased retinal microvascular abnormalities. However, the molecular link between inflammation and microvascular degeneration remains elusive. Thioredoxin-interacting protein (TXNIP) is recognised as an activator of the NOD-like receptor pyrin domain containing-3 (NLRP3) inflammasome. This study aims to examine TXNIP expression and elucidate its role in endothelial inflammasome activation and retinal lesions. METHODS: Spontaneously hypertensive (SHR) and control Wistar (W) rats were compared with groups fed a high-fat diet (HFD) (W+F and SHR+F) for 8-10 weeks. RESULTS: Compared with W controls, HFD alone or in combination with hypertension significantly induced formation of acellular capillaries, a hallmark of retinal ischaemic lesions. These effects were accompanied by significant increases in lipid peroxidation, nitrotyrosine and expression of TXNIP, nuclear factor κB, TNF-α and IL-1ß. HFD significantly increased interaction of TXNIP-NLRP3 and expression of cleaved caspase-1 and cleaved IL-1ß. Immunolocalisation studies identified TXNIP expression within astrocytes and Müller cells surrounding retinal endothelial cells. To model HFD in vitro, human retinal endothelial (HRE) cells were stimulated with 400 µmol/l palmitate coupled to BSA (Pal-BSA). Pal-BSA triggered expression of TXNIP and its interaction with NLRP3, resulting in activation of caspase-1 and IL-1ß in HRE cells. Silencing Txnip expression in HRE cells abolished Pal-BSA-mediated cleaved IL-1ß release into medium and cell death, evident by decreases in cleaved caspase-3 expression and the proportion of live to dead cells. CONCLUSIONS/INTERPRETATION: These findings provide the first evidence for enhanced TXNIP expression in hypertension and HFD-induced retinal oxidative/inflammatory response and suggest that TXNIP is required for HFD-mediated activation of the NLRP3 inflammasome and the release of IL-1ß in endothelial cells.

Hepatitis E virus (HEV) is a common cause of viral hepatitis worldwide. Genotypes 1 and 2 cause acute hepatitis in endemic regions (Asia and Africa), whereas genotypes 3 and 4 (America and Europe) result in sporadic acute or chronic hepatitis, specifically in certain groups. HEV infections are rising because of increased transplantation rates and immunosuppression. We report a 75-year-old heart transplant patient with nonspecific symptoms, diagnosed with HEV chronic hepatitis. Despite ribavirin-induced hemolytic anemia, the patient achieved sustained virological response and normalization of liver enzymes.
RESUMO
Colonic variceal bleeding is a rare cause of lower gastrointestinal (GI) bleeding, which carries a high mortality rate. Due to limited data, the optimal management of colonic variceal bleeding is not known. Coil-assisted retrograde transvenous obliteration (CARTO) has been shown to be very effective in managing non-esophageal variceal bleeding, but only a few cases demonstrate its effectiveness in treating colonic variceal bleeding. Here we present a case of colonic variceal bleeding treated with CARTO in order to expand on the limited body of evidence showing its efficacy in effectively treating this rare cause of life-threatening GI bleeding.
RESUMO
Objective: Nonalcoholic fatty liver disease (NAFLD) or metabolic dysfunction-associated steatotic liver disease (MASLD) is a significant contributor to chronic liver disease worldwide. Orlistat blocks intestinal fat absorption, leading to decreased liver fat content. Therefore, it is a viable option for NAFLD management. Methods: We performed a systematic review and metaanalysis using randomized controlled trials (RCTs). We used mean difference (MD) to pool continuous outcomes presented with the corresponding confidence interval (CI). Results: We included four RCTs with a total of 379 patients. Orlistat was effective in reducing liver fat content (MD: -5.02, 95% CI [-7.23, -2.82], P = 0.00001), alanine transferase (MD: -10.03, 95% CI [-17.80, -2.26], P = 0.01), aspartate transferase (MD: -4.29, 95% CI [-7.59, -0.99], P = 0.01), waist circumference (MD: -3.18, 95% CI [-4.25, -2.10], P = 0.00001), body mass index (MD: -1.03, 95% CI [-1.34, -0.73], P = 0.00001), total cholesterol (MD: -3.75, 95% CI [-4.02, -3.49], P = 0.00001), and low-density lipoprotein (MD: -3.83, 95% CI [-4.05, -3.61], P = 0.00001). However, orlistat was associated with increased serum triglycerides (MD: 7.46, 95% CI [6.48, 8.44], P = 0. 00001). Conclusion: Orlistat is a viable option for NAFLD management; however, it increases triglyceride levels. Larger RCTs are required.
RESUMO
Metabolic dysfunction-associated steatotic liver disease (MASLD) is characterized by hepatic steatosis and metabolic dysregulation. Growth hormone (GH) augmentation has emerged as a potential therapeutic intervention for treating MASLD. This systematic review and meta-analysis aimed to evaluate the impact of GH augmentation on different parameters of MASLD. A systematic literature search identified randomized controlled trials investigating GH augmentation in MASLD patients. Search results were screened via Covidence and the Risk of Bias 2 tool was used to assess bias in randomized controlled trials. Statistical analysis utilized RevMan v5.3. We combined dichotomous outcomes employing odds ratios and continuous outcomes utilizing mean difference (MD), each with a 95% confidence interval (CI). Statistical significance was indicated by a P-value less than 0.05. Heterogeneity was evaluated using I2 tests. Our results showed that GH augmentation resulted in a significant reduction in both relative (MD: -46.26; 95% CI: -71.52, -21.00; Pâ =â 0.0003) and absolute (MD: -5.15; 95% CI: -7.93, -2.37; Pâ =â 0.0003) hepatic fat fraction. GH augmentation significantly reduced alanine aminotransferase (MD: -5.97; 95% CI: -10.31, -1.62; Pâ =â 0.007) and gamma-glutamyl transferase (MD: -16.18; 95% CI: -30.76, -1.59; Pâ =â 0.03) levels. No significant changes were observed in hemoglobin A1c, C-reactive protein, fasting serum glucose, BMI, triglycerides, and low-density lipoprotein cholesterol levels. Our meta-analysis highlights GH augmentation as a promising therapy for reducing liver steatosis and improving liver enzyme levels in MASLD patients. Further large-scale trials are warranted to examine the long-term effects, safety profiles, and potential impact on various measures.
RESUMO
Background and Aim: Etrolizumab is a gut-targeted anti-ß7 integrin monoclonal antibody. However, the evidence of etrolizumab efficacy and safety in ulcerative colitis remains inconclusive. Therefore, we aim to evaluate the safety and efficacy of etrolizumab as an induction and maintenance therapy for active moderate to severe ulcerative colitis. Methods: We synthesized randomized controlled studies (RCTs) from MEDLINE, Scopus, EMBASE, PubMed, Web of Science, and Cochrane Library until April 2023. The risk ratio (RR) for dichotomous outcomes with the corresponding 95% confidence interval (CI) was used. The study protocol was registered in PROSPERO with ID: CRD42023437040. Results: Five RCTs with 1849 participants were included. The etrolizumab group had a significant clinical response (RR: 1.28 with 95% CI [1.08, 1.51], P = 0.005), clinical remission rates during the induction phase (RR: 2.47 with 95% CI [1.48, 4.11], P = 0.0005), compared with the placebo group in ulcerative colitis; however, there was no statistically significant difference between the two groups, regarding the corticosteroids-free remission rate (RR: 1.92 with 95% CI [0.94, 3.92], P = 0.07). Moreover, endoscopic improvement, endoscopic remission, and histologic remission rates were observed more in the etrolizumab group during both the induction and maintenance phases. For safety outcomes, etrolizumab was significantly safer, but any adverse event was higher in the etrolizumab group than in the placebo. Conclusion: Etrolizumab shows its effectiveness as both an induction and maintenance therapy for moderate or severe UC. The findings demonstrate its positive impact on clinical, endoscopic, and histologic remission rates. Regarding safety, other than any side effects, etrolizumab showed a good safety than a placebo.
RESUMO
Metabolic dysfunction-associated steatotic liver disease (MASLD) is a prevalent metabolic disorder characterized by excessive hepatic fat accumulation. Intermittent fasting (IF) has emerged as a potential therapeutic strategy with the ability to induce weight loss, improve insulin sensitivity and reduce hepatic steatosis. We aim to compare the efficacy of different IF regimens for MASLD management. A systematic review and network meta-analysis of randomized controlled trials investigating different IF regimens for MASLD. PubMed , EMBASE , WOS , SCOPUS and Cochrane Central Register of Controlled Trials were searched until 10 April 2023. Analysis was performed using R software with the meta and netmeta packages. Mean difference (MD) was used to pool continuous outcomes with 95% confidence intervals (CIs). Our meta-analysis was registered in PROSPERO (CRD42023418467). Our meta-analysis included eight randomized controlled trials with a total of 635 participants. The 5â :â 2 diet significantly improved liver stiffness (MD, -0.32; 95% CI, -0.55 to -0.09; P â <â 0.01). Time-restricted feeding significantly improved liver steatosis (controlled attenuation parameter score) (MD, -39.83; 95% CI, -64.78 to -14.87; P â <â 0.01). No significant changes were observed in asparate aminotransferase, gamma-glutamyl transpeptidase, low-density lipoproteins cholesterol, total cholesterol, triglyceride levels, basal metabolic index, blood pressure, Homeostatic Model Assessment of Insulin Resistance, fasting blood sugar, lean body mass or waist circumference across all IF regimens. However, alternate-day fasting showed positive results in anthropometric measures, including significant improvements in lean body mass, waist circumference, fat mass and weight reduction ( P â <â 0.05). IF regimens showed various positive effects on clinical outcomes in MASLD patients; however, these effects were not consistent. Therefore, a patient-tailored IF regimen should be considered.

INTRODUCTION: Gastrointestinal (GI) bleeding stemming from malignant tumors is increasingly recognized, due to advancements in oncology and detection methods. Traditional endoscopic hemostatic techniques have shown variable success rates in managing hemorrhagic GI neoplasms. Hemospray, an emerging endoscopic hemostatic powder, offers promise in treating upper GI bleeding, potentially extending its utility to neoplastic bleeding sites. This meta-analysis aims to evaluate Hemospray's efficacy in managing bleeding related to GI tumors. METHODS: We searched Embase, Scopus, Web of Science, Medline/PubMed, and Cochrane. Inclusion criteria encompassed studies focusing on malignancy-related GI bleeding and interventions utilizing Hemospray. Comparative studies contrasted Hemospray with standard endoscopic treatments (SET), while noncomparative studies assessed Hemospray's efficacy independently. The risk of bias was assessed using appropriate tools, and statistical analyses were performed using Review Manager and open Meta analyst software. RESULTS: We included 19 studies in our meta-analysis. Hemospray demonstrated higher rates of immediate hemostasis compared to SET (odds ratio: 17.14, 95% confidence interval: 4.27-68.86), with consistent outcomes across studies. Rebleeding rates at 14 and 30 days were comparable between Hemospray and SET groups, suggesting similar efficacy in long-term hemostasis. Hemospray showed a significantly lower need for nonendoscopic hemostasis compared to SET (odds ratio: 0.51, 95% confidence interval: 0.30-0.87), indicating a potential reduction in supplementary interventions. Safety assessments revealed no confirmed adverse events directly linked to Hemospray. CONCLUSION: This meta-analysis highlights Hemospray's efficacy in achieving immediate hemostasis in GI tumor-related bleeding, with potential benefits in reducing supplementary interventions and improving patient outcomes. Despite comparable rebleeding rates, Hemospray emerges as a valuable adjunctive therapy in managing malignant GI bleeding.
RESUMO
Worldwide, a majority of routine endoscopic procedures are performed under some form of sedation to maximize patient comfort. Propofol, benzodiazepines and opioids continue to be widely used. However, in recent years, Remimazolam is gaining immense popularity for procedural sedation in gastrointestinal (GI) endoscopy. It is an ultra-short-acting benzodiazepine sedative which was approved by the Food and Drug Administration in July 2020 for use in procedural sedation. Remimazolam has shown a favorable pharmacokinetic and pharmacodynamic profile in terms of its non-specific metabolism by tissue esterase, volume of distribution, total body clearance, and negligible drug-drug interactions. It also has satisfactory efficacy and has achieved high rates of successful sedation in GI endoscopy. Furthermore, studies have demonstrated that the efficacy of Remimazolam is non-inferior to Propofol, which is currently a gold standard for procedural sedation in most parts of the world. However, the use of Propofol is associated with hemodynamic instability and respiratory depression. In contrast, Remimazolam has lower incidence of these adverse effects intra-procedurally and hence, may provide a safer alternative to Propofol in procedural sedation. In this comprehensive narrative review, highlight the pharmacologic characteristics, efficacy, and safety of Remimazolam for procedural sedation. We also discuss the potential of Remimazolam as a suitable alternative and how it can shape the future of procedural sedation in gastroenterology.
RESUMO
BACKGROUND: Gallbladder cancer (GBC) is an aggressive malignancy that is usually diagnosed at a late stage. Prior data showed increasing incidence of GBC in the US. However, little is known about race/ethnic-specific incidence and mortality trends of GBC per stage at diagnosis. Therefore, we aimed to conduct a time-trend analysis of GBC incidence and mortality rates categorized by race/ethnicity and stage-at-diagnosis. METHODS: Age-adjusted GBC incidence and mortality rates were calculated using SEER*Stat software from the United States Cancer Statistics database (covers ~98% of US population between 2001 and 2020) and NCHS (covers ~100% of the US population between 2000 and 2020) databases, respectively. Race/Ethnic groups were Non-Hispanic-White (NHW), Non-Hispanic-Black (NHB), Hispanic, Non-Hispanic-Asian/Pacific-Islander (NHAPI), and Non-Hispanic-American-Indian/Alaska-Native (NHAIAN). Stage-at-diagnoses were all stages, early, regional, and distant stages. Joinpoint regression was used to generate time-trends [annual percentage change (APC) and average APC (AAPC)] with parametric estimations and a two-sided t-test (p-value cut-off 0.05). RESULTS: 76,873 patients were diagnosed with GBC with decreasing incidence rates in all races/ethnicities except NHB who experienced an increasing trend between 2001 and 2014 (APC = 2.08, p < 0.01) and plateauing afterward (APC = -1.21, p = 0.31); (AAPC = 1.03, p = 0.03). Among early-stage tumors (9927 patients), incidence rates were decreasing only in Hispanic (AAPC = -4.24, p = 0.006) while stable in other races/ethnicities (NHW: AAPC = -2.61, p = 0.39; NHB: AAPC = -1.73, p = 0.36). For regional-stage tumors (29,690 patients), GBC incidence rates were decreasing only in NHW (AAPC = -1.61, p < 0.001) while stable in other races/ethnicities (NHB: AAPC = 0.73, p = 0.34; Hispanic: AAPC = -1.58, p = 0.24; NHAPI: AAPC = -1.22, p = 0.07). For distant-stage tumors (31,735 patients), incidence rates were increasing in NHB (AAPC = 2.72, p < 0.001), decreasing in Hispanic (AAPC = -0.64, p = 0.04), and stable in NHW (AAPC = 0.07, p = 0.84) and NHAPI (AAPC = 0.79, p = 0.13). There were 43,411 deaths attributed to GBC with decreasing mortality rates in all races/ethnicities except NHB who experienced a stable trend (AAPC = 0.25, p = 0.25). CONCLUSION: Nationwide data over the last two decades show that NHB patients experienced increasing GBC incidence between 2001 and 2014 followed by stabilization of the rates. This increase was driven by late-stage tumors and occurred in the first decade. NHB also experienced non-improving GBC mortality, compared to other race and ethnic groups who had decreasing mortality. This can be due to lack of timely-access to healthcare leading to delayed diagnosis and worse outcomes. Future studies are warranted to investigate contributions to the revealed racial and ethnic disparities, especially in NHB, to improve early detection.

Hepatitis C virus (HCV) is a major global health concern, particularly in Egypt, due to historic schistosomiasis control efforts that inadvertently led to widespread HCV transmission. This study aimed to evaluate the efficacy of Egypt's national strategies in controlling and reducing the prevalence of HCV, including introducing sofosbuvir and implementing the "100 Million Healthy Lives" campaign. The approach includes a review of epidemiological data, an analysis of the national HCV control strategies implemented, and an assessment of their outcomes, focusing on the period from 2006 to 2022. Significant milestones were achieved, including a drastic reduction in new HCV infections from 300 per 100,000 in 2014 to 9 per 100,000 in 2022 and successful treatment of over 4 million people. Egypt has become the first country in the world to achieve the "gold tier" status based on World Health Organization criteria on the path to eradication of HCV. Egypt's comprehensive approach can serve as a model for similar endemic regions. Other nations with high HCV prevalence might benefit from adopting similar multidimensional strategies, emphasizing prevention and treatment.
RESUMO
Introduction: Burnout, resilience, and thriving significantly impact academics, particularly in health professions, where responsibilities are extensive. This study aimed to explore these constructs among academic health professionals, examining sociodemographic and work-related factors influencing these outcomes. Methods: A cross-sectional study was conducted among academic health professionals via web-based professional networks from August 2022 to February 2023. Validated tools were used, and descriptive and inferential statistics were applied. Results: 505 participants were included, predominantly female (63%), with a mean age of 38.15 ± 9.6 years. High burnout was reported by 10.9%, 13.7% experienced exhaustion, and 6.3% were disengaged. Resilience and thriving were moderate at 59.2 and 51.9%, respectively. Age correlated negatively with burnout (r = -0.131, p = 0.003) but positively with resilience (r = 0.178, p < 0.001). Females reported higher exhaustion (p = 0.014), while males showed greater resilience (p = 0.016). Instructors exhibited lower resilience compared to assistant professors (p < 0.001) and associate professors (p < 0.001). Those at public universities reported higher exhaustion than those at private universities (p < 0.001). Conclusion: Variable levels of burnout, resilience, and thriving were observed among academic health professionals, influenced by sociodemographic and work-related factors. Interventions targeting resilience and thriving may mitigate burnout risk and enhance engagement among academics in health professions.
