Preparation and anti-colon cancer effect of a novel curcumin analogue (CA8): in vivo and in vitro evaluation

Chemotherapy remains the first choice of treatment for colon cancer despite the inevitable adverse effects. Curcumin (CU) possesses antitumor activity but has poor aqueous solubility, low bioavailability, and weak activity. To address this, nine novel monocarbonyl CU analogues were designed, synthesized, and evaluated in the present study. Among them, CA8 exhibited the highest water solubility, which was approximately 2.37 × 106 times that of CU. In addition, compared with CU, its cytotoxicity on Caco-2 cells (19.2 times/48 h) was stronger. Of note, CA8 arrestedthe cell cycle of Caco-2 cells at the G2/M phase and induced apoptosis. Meanwhile, acute toxicity experiments indicated that KM mice tolerated CA8 for up to 300 mg/kg CA8 (oral administration) and 50 mg/kg CA8 (intraperitoneal injection). The oral administration of CA8 to Sprague Dawley rats exhibited higher AUC (0-t) (6.23-fold) and longer MRT (0-t) (3.35-fold) than that of CU. CA8 also inhibited the proliferation and angiogenesis of tumor cells more than CU and tegafur. Finally, CA8 may exert anti-tumor effects through the activation of JNK pathway and inhibition of AKT pathway. These results suggest that CA8 is a safe and highly effective new drug for colon cancer treatment.

SURG-22. BRAIN METASTASIS FROM ADVANCED GASTRIC CANCERS: HIGH INCIDENCE OF LEPTOMENINGEAL DISSEMINATION AND ITS CLINICAL IMPACT ON SURVIVAL

Abstract OBJECTIVE Advanced gastric cancer is one of the most common and fatal cancers worldwide, and due to its highest incidence rate in Eastern Asian, it is steadily considered important. However, brain metastasis from advanced gastric cancer is very rare, and its incidence is reported as less than 1% of patients with primary advanced gastric cancer. There have been very few studies describing on the incidence and clinical outcome of patients with brain metastasis from advanced gastric cancers. METHOD We retrospectively analyzed 128 patients diagnosed as brain metastasis from advanced gastric cancers, and then underwent treatment from 2005 to 2021 April in our institution. Patients’ survival and its associated prognostic factors were evaluated. Especially, subgroup analysis on patients with leptomeningeal dissemination (LMD) was performed. RESULT Of total 128 patients of advanced gastric cancer with brain metastasis, 74 patients (58%) were diagnosed with LMD. Overall survival of LMD group was significantly shorter than that of non-LMD group (p<0.001). Patients treated with tumor removal (TR) followed by whole brain radiotherapy (WBRT) showed superior overall survival than patients with WBRT alone (p=0.002). Among 74 LMD patients, those who underwent WBRT combined with intrathecal methotrexate (IT MTX) showed better outcome than patients with WBRT alone (p=0.025). Specifically, for the 51 pure LMD patients without parenchymal brain metastasis, the superiority of adjuvant IT TMX on survival outcome was more apparent (p=0.011). CONCLUSION The incidence of LMD has been underestimated as 58% of patient with brain metastasis from advanced gastric cancers presented LMD on radiological and cytological studies. If the brain tumor is surgically resectable, TR followed by WBRT can be the first choice of treatment provides survival benefit. Patients with LMD are most benefited from IT MTX combined with WBRT.

Comparative efficacy, toxicity, and insulin-suppressive effects of simvastatin and pravastatin in fatty acid-challenged mouse insulinoma MIN6 β-cell model

IntroductionFamilial hypercholesterolemia, the highly prevalent form of dyslipidemia, is a well-known risk factor for premature heart disease and stroke worldwide. Statins, which inhibit 3-hydroxy 3-methylglutaryl coenzyme A (HMG-CoA) reductase, are the first-choice treatment for dyslipidemias, and have been effective in reducing the risk of stroke and myocardial infarction. However, emerging evidence indicates that statins may increase the incidence of new-onset type 2 diabetes by reducing β-cell mass and function. Notably, past in vitro reports studying the effects of statins on β-cells were performed without including free fatty acids in the model. This factor should have been addressed since these agents are used to treat individuals with hyperlipidemia.MethodsHere, we used a mouse insulinoma MIN6 β-cell culture model to assess the efficacy, cytotoxicity, and insulin-suppressive effects of simvastatin and pravastatin in the presence of palmitic, linoleic, and oleic acids cocktail to mimic mixed lipids challenge in a biologically relevant setting.Results and discussionOur findings indicate that simvastatin was more effective in lowering intracellular cholesterol but was more cytotoxic as compared to pravastatin. Similarly, simvastatin exhibited a higher suppression of total insulin content and insulin secretion. Both drugs suppressed insulin secretion in phases 1 and 2, dose-dependently. No significant effect was observed on mitochondrial respiration. More importantly, elution experiments showed that insulin content diminution by simvastatin treatment was reversible, while exogenous mevalonate did not improve total insulin content. This suggests that simvastatin's influence on insulin content is independent of its specific inhibitory action on HMG-CoA reductase. In conclusion, our study identified that simvastatin was more effective in lowering intracellular cholesterol, albeit it was more toxic and suppressive of β-cells function. Notably, this suppression was found to be reversible.

A IMPORTÂNCIA DA EDUCAÇÃO PERMANENTE PARA OS AGENTES COMUNITÁRIOS DE SAÚDE NO ACOMPANHAMENTO DE PACIENTES COM SÍNDROME METABÓLICA

Metabolic syndrome (MS) is a series of metabolic disorders or abnormalities that together are considered risk factors in the same individual for the development of diabetes and cardiovascular diseases. artery, with the dietary plan being the treatment of first choice. Community health agents play an important role in helping to promote health and prevent diseases through home care, in addition to creating links with the community, promoting humanization, acceptance and accountability. They also provide guidance to the population on the use of and access to health system services. They have great responsibility in educating patients, enhancing health care actions. Community health agents encounter difficulties in carrying out educational work, often caused by the community due to the culture of medicalization, in addition to there being people in the community without comorbidity repressing the capacity of health education to carry out prevention. Therefore, the importance of educational practices is undeniable, as from them society obtains sufficient information to opt for healthier choices and modify their risk behaviors, resulting in a reduction in cases of metabolic syndrome.

Expert opinion on heat therapy for teenagers' musculoskeletal pain management.

Among children and adolescents, up to 40% will experience musculoskeletal pain (MP), which can significantly impair functional ability, reduce quality of life, cause emotional distress, and lead to sleeping disorders for both patients and their families. The first-line treatment often involves pharmacological interventions, even though there is a lack of evidence supporting the efficacy or the safety of this approach in this specific age group. Recent guidelines recommend the implementation of preventative strategies and physical tools as the first option to minimize the use of medications. We aimed to provide an expert opinion on the use of heat therapy for MP management in young patients. This paper is the result of a virtual advisory board held by the authors in order to discuss and provide an expert opinion about the use of heat therapy in MP in children and adolescents. MP is a significant burden affecting children and adolescents. While non-steroidal anti-inflammatory drugs are currently the first-choice treatment of acute and chronic MP in children and adolescents, avoiding or reducing them in such patients is advisable, to reduce side effects and to prevent the development of chronic pain and medication overuse headaches. Heat therapy can be an additional treatment option due to its ability to promote muscle relaxation, enhance blood circulation, and modulate nociceptors with a good safety profile. MP in children and adolescents is a common condition that should be approached multidisciplinary, including information, therapeutic exercise and physical therapies like hot or cold therapies. Future studies should be conducted to evaluate the safety, efficacy and indications of each treatment in MP.

Exome Sequence Data of Eight SLC Transporters Reveal That SLC22A1 and SLC22A3 Variants Alter Metformin Pharmacokinetics and Glycemic Control.

Background: Type 2 diabetes (T2D) is one of the leading causes of mortality and is a public health challenge worldwide. Metformin is the first-choice treatment for T2D; its pharmacokinetics (PK) is facilitated by members of the solute carrier (SLC) superfamily of transporters, it is not metabolized, and it is excreted by the kidney. Although interindividual variability in metformin pharmacokinetics is documented in the Mexican population, its pharmacogenomics is still underexplored. We aimed to identify variants in metformin SLC transporter genes associated with metformin PK and response in Mexican patients. Methods: Using exome data from 2217 Mexican adults, we identified 86 biallelic SNVs in the eight known genes encoding SLC transporters, with a minor allele frequency ≥ 1%, which were analyzed in an inadequate glycemic control (IGC) association study in T2D metformin treated patients. Metformin PK was evaluated in a pediatric cohort and the effect of associated SNVs was correlated. Results: Functional annotation classified two SNVs as pathogenic. The association study revealed two blocks associated with IGC. These haplotypes comprise rs622591, rs4646272, rs4646273, and rs4646276 in SLC22A1; and rs1810126 and rs668871 in SLC22A3. PK profiles revealed that homozygotes of the SLC22A1 haplotype reached lower plasma metformin concentrations 2 h post administration than the other groups. Conclusions: Our findings highlight the potential of pharmacogenomics studies to enhance precision medicine, which may involve dosage adjustments or the exploration of alternative therapeutic options. These hold significant implications for public health, particularly in populations with a high susceptibility to develop metabolic diseases, such as Latin Americans.

The impact of scabies in tent cities in Kahramanmaraş after the Turkish earthquakes: oral pharmacologic treatment efficacy

Background Our study was conducted to determine the impact of scabies in people living in collective living areas such as tent cities and container cities after the February 6 Kahramanmaraş earthquakes and to show the effectiveness of oral ivermectin treatment on scabies cases because topical treatments could not be used in this period when access to water was limited. Methods Among 233 patients diagnosed and treated with scabies in tent and container cities, 192 patients who met the criteria were included in the study. Descriptive statistics were given as number (n), percentage (%), mean, median, standard deviation (SD). In the comparison of categorical data, the chi-square test was applied; in the comparison of numerical data ANOVA analyses was applied. Results A total of 192 scabies patients (82.4%), 47.9% (N:92) of whom were women, were included in the study. The frequency of scabies in the total population in tent cities and container cities was found to be at least 0.54%. The most common symptoms were pruritis (99.0%) and rash (97.9%). The most common sites of lesion involvement were the umbilicus (87.0.%), forearm (75.0%), and back (70.3%). After the first dose of ivermectin, 159 (82.8%) patients showed complete recovery, while 30 (15.6%) patients showed partial recovery. 3 (1.6%) patients showed no improvement. After the second dose of ivermectin, 173 (90.1%) patients showed complete recovery. There were two (1.0%) patients who did not show improvement after two doses. Due to the deterioration of urban infrastructure after devastating earthquakes, the irregularity of mass living areas, the lack of hygiene conditions, and the difficulty of accessing clean, usable water, oral ivermectin may be the first choice for treatment in terms of ease of use and effectiveness.

Laparoscopic abdominoperineal resection and myocutaneous flap reconstruction for anal fistula cancer arising from complicated anal fistula: two case reports.

Anal fistula cancer is rare and definitive treatment has not yet been established. Laparoscopic abdominoperineal resection is generally the first choice of treatment if the cancer is determined to be resectable. However, complicated anal fistula cancer often requires extensive resection. Using a myocutaneous flap for reconstruction after resection in such cases, radical resection can be performed regardless of the size of the anal fistula cancer. We report two cases in which we performed laparoscopic abdominoperineal resection with extensive buttock resection and myocutaneous flap reconstruction for widespread anal fistula cancer. One of the cases was reconstruction with a posterior thigh flap, the other was with a bilateral expanded gluteus maximus flap. Both cases were anal fistula cancers that developed from complicated anal fistulas. If the size of anal fistula cancer is large and extended buttock resection is necessary, radical resection of anal fistula cancer is possible using myocutaneous flap for reconstruction after extended abdominoperineal resection.

Application of nanoparticles as surface modifiers of dental implants for revascularization/regeneration of bone

BackgroundOsseointegrated dental implants are widely established as a first-choice treatment for the replacement of missing teeth. Clinical outcomes are however often compromised by short or longer-term biological complications and pathologies. Nanoparticle-coated materials represent a very active research area with the potential to enhance clinical outcomes and reduce complications of implant therapy. This scoping review aimed to summarize current research on various types of nanoparticles (NPs) used as surface modifiers of dental implants and their potential to promote biological and clinical outcomes.MethodsA systematic electronic search was conducted in SCOPUS, PubMed and Google Scholar aiming to identify in vivo, in situ, or in vitro studies published between 2014 and 2024. Inclusion and exclusion criteria were determined and were described in the methods section.ResultsA total of 169 articles (44 original papers from Scopus and PubMed, and 125 articles from Google Scholar) were identified by the electronic search. Finally, 30 studies fit the inclusion criteria and were further used in this review. The findings from the selected papers suggest that nanoparticle-coated dental implants show promising results in enhancing bone regeneration and promoting angiogenesis around the implant site. These effects are due to the unique physicochemical properties of nanoparticle-coated implants and the controlled release of bioactive molecules from nanoparticle-modified surfaces.ConclusionNanoscale modifications displayed unique properties which could significantly enhance the properties of dental implants and further accelerate revascularization, and osseointegration while facilitating early implant loading. Yet, since many of these findings were based on in-vitro/in-situ systems, further research is required before such technology reaches clinical application.

Reconstruction methods in vulvar cancer: a narrative review

Background : Vulvar cancer is a rare type of cancer that accounts for 1% of all cancers in women and about 3-8% of all gynecological cancers in the world. Although resection of the lesion is the first choice for treatment, reconstructive methods of the vulva have been increasingly used recently. Flaps are most commonly used for this purpose. However, it is important to remember that the reconstruction must be adjusted to the patient's needs, taking into account the geometry of the wound, as well as potential secondary complications.Aim of the study: The aim of this study is to present the different methods of plastic surgery for vulvar cancer, which included V-Y, VRAM, ALT, DIEP and lotus flaps. The following article focuses on describing the above methods, presenting their advantages and disadvantages, in which cases they can be used, and potential complications.Material and methods: The literature review was conducted in the PubMed database. The inclusion criteria used in the review included compliance with topic, publication date after 2015 and English language. Articles of low credibility, duplicated, not in English language and with abstracts unrelated to the topic were excluded. Results: Of the articles found, 32 studies were eventually to be reviewed. The research shows that the choice of reconstruction method can be difficult, while there is no single correct approach in vulvar cancer cases.Conclusions: In summary, the interdisciplinary collaboration between the gynecologist oncologist, the surgeon and the radiotherapist, plays a key role in the treatment process.

Endoscopic biliary drainage for distal bile duct obstruction due to pancreatic cancer.

Approximately 60% of pancreatic cancers occur in the pancreatic head and may present as obstructive jaundice due to bile duct invasion. Obstructive jaundice often leads to poor general conditions and acute cholangitis, interfering with surgery and chemotherapy and requiring biliary drainage. The first choice of treatment for biliary drainage is the endoscopic transpapillary approach. In unresectable tumors, self-expandable metal stents (SEMSs) are most commonly used and are classified into uncovered and covered SEMSs. Recently, antireflux metal stents and large- or small-diameter SEMSs have become commercially available, and their usefulness has been reported. Plastic stents are infrequently used in patients with resectable biliary obstruction; however, owing to the recent trend in preoperative chemotherapy, SEMSs are frequently used because of the long time to recurrent biliary obstruction. Endoscopic ultrasound-guided biliary drainage (EUS-BD) is often performed in patients who are not eligible for the transpapillary approach, and favorable outcomes have been reported. Different EUS-BD techniques and specialized stents have been developed and can be safely used in high-volume centers. The indications for EUS-BD are expected to further expand in the future.

Hepatotoxicity due to albendazole: safe alternatives for echinococcosis therapy

Infection with Echinococcus multilocularis leads to the clinical manifestation of alveolar echinococcosis. This is characterized by the formation of alveolar liver tumours, which usually disintegrate necrotically in the course of the disease. Pseudocysts are formed. Especially in the early stages, curative resection followed by long-term treatment with albendazole is recommended. However, the majority of patients are not amenable to curative surgery. In these cases, albendazole therapy is the first-choice treatment. We present arare case of albendazole-associated hepatitis in apatient with inoperable Echinococcus multilocularis infection, with afavourable outcome following achange in treatment to mebendazole.

Myopic Maculopathy Stabilization in a Child with Progressive Complicated Myopia and Underlying Connective Tissue Dysplasia via Optical Therapy with HAL Spectacle Lenses Inducing Retinal Peripheral Defocus: Clinical Case

Background. Myopia is a serious medical and social problem specifically due to the high risk of such complications as cataracts, myopic maculopathy, glaucoma, and retinal detachment. Children with connective tissue dysplasia (CTD) syndrome are most subjected to myopia. Prevention of myopia progression in children remains the only effective way to prevent myopic maculopathy. Significant progress in this field has been achieved via optical technologies developed on the basis of peripheral defocus theory. Clinical case description. Patient, 10 years old, with CTD, mild myopia of both eyes with rapid progression, myopic maculopathy, grade 1. Ophthalmic status: spheroequivalent refraction — right eye (–)1.5 diopters / left eye (–)1.75 diopters; vision acuity with monocular correction — 1.0. Fundoscopy: optic disc is pale pink, with clear borders, arteries and veins are well-proportioned, their courses and calibers are intact; choriocapillary layer attenuation in the macular and paramacular zones, “parquet fundus”; areas of pigment redistribution on peripheral retina; no atrophic foci detected; anterior-posterior axis of the right and left eyes — 26.2 and 26.3 mm, respectively. Optical coherence tomography (OCT) has revealed retinal thinning in the upper and nasal sectors in the right eye during the first assessment. The left eye has demonstrated losses of retinal thickness within the middle parafoveal zone and significant thinning in the upper segment. Optical therapy with HAL spectacle lenses (inducing volumetric myopic peripheral defocus) was assigned to control myopia to slow down the pathological axial growth of the child's eyes and to stabilize refraction. 4 months of wearing glasses with HAL lenses has led to the stabilization of dystrophic changes in retina, signs of improvement in several sectors by were observed on OCT. No negative changes were revealed in all parafoveal segments of the left eye. The child was recommended to continue wearing glasses with HAL lenses with dynamic follow-up every 3 months. Conclusion. CTD in children is associated with high risk of complications in case of myopia progression, moreover, retinal pathology can occur even with mild myopia. Optical therapy with HAL spectacle lenses is effective and safe first treatment of choice in the control of myopia in children with CTD, and opens new opportunities in prevention of progressive myopia disabling complications in children, whose treatment results were not previously sufficient.

Updates on Endoscopic Stenting for Unresectable Malignant Hilar Biliary Obstruction.

Malignant hilar biliary obstruction (MHBO) can cause obstructive jaundice and/or cholangitis necessitating appropriate biliary drainage. Endoscopic biliary stenting is the first-choice treatment, especially in unresectable cases, owing to its minimally invasive nature and utility. However, the hilar region is complex because of the branching and curving of bile ducts, making strictures in this area more complicated. Therefore, MHBO stenting is challenging, and treatment strategies have yet to be established. Furthermore, recent advances in antitumor therapies have altered the background surrounding the development of stenting strategies. Therefore, it is necessary to understand and grasp the current evidence well and to accumulate additional evidence reflecting the current situation. This study reviews the current status, issues, and prospects of endoscopic stenting for MHBO, especially in unresectable cases.

Nationwide survey analysis of esophagogastric varices in portal hypertension based on endoscopic management in China

AbstractAimsThe endoscopic treatment of esophagogastric varices is challenging, and the nationwide application of endoscopic therapies for various types of esophagogastric varices and different clinical scenarios remains unclear. This study investigated the use of endoscopic therapy for portal hypertension in China.MethodsThis study used a questionnaire survey initiated by the Liver Health Consortium in China to investigate the use of endoscopic therapies for portal hypertension. Questionnaires were released online from January 30, 2023 to February 28, 2023 and filled out by chief physicians or senior instructors responsible for endoscopic therapies in participating hospitals across 31 provinces (autonomous regions and municipalities) in China. Comparisons of guideline adherence between primary and referral medical centers were performed using the chi‐square test or Fisher's exact test.ResultsIn total, 836 hospitals participated in the survey. For primary and secondary prophylaxis of esophagogastric variceal bleeding (EGVB), adherence to the national guidelines was 72.5% (606/836) and 39.2% (328/836), respectively. Significant differences were observed in the rate of adherence between the primary and referral centers for primary (79.9% [111/139] vs. 71.0% [495/697], p = 0.033) and secondary prophylaxis (27.3% [38/139] vs. 41.6% [290/697], p = 0.002). Of the hospitals, 78.2% (654/836) preferred endoscopic therapies for acute EGVB, and the timing of endoscopy was usually within 12 h (48.5%, 317/654) and 12–24 h (36.9%, 241/654) after bleeding. Endoscopic therapy was more likely to be the first choice of treatment for acute EGVB in referral centers than in primary centers (82.6% [576/697] vs. 56.1% [78/139], p < 0.001). Regarding the management of gastroesophageal varices type 2 and isolated gastric varices type 1, the most prevalent procedures were cyanoacrylate injection combined with sclerotherapy (48.2% [403/836] and 29.9% [250/836], respectively); however, substantial hospitals preferred clip‐assisted therapies (12.4% [104/836] and 26.4% [221/836], respectively). Nonselective beta‐blockers were routinely used in 73.4% (614/836) of hospitals during the perioperative period of EGVB management, and propranolol (88.8%, 545/614) and carvedilol (37.5%, 230/614) were the most widely used nonselective beta‐blockers.ConclusionsThis survey clarified that various endoscopic procedures have been implemented nationwide in China. Participating hospitals have actively performed emergent endoscopy for acute EGVB; however, these hospitals do not adequately follow recommendations regarding primary and secondary prophylaxis of EGVB. In the future, standardizing the selection of endoscopic procedures and improving compliance with guidelines is crucial.

Comparison of the Effectiveness of Transarterial Bland Embolization and Transarterial Chemoembolization for Intermediate-Stage Hepatocellular Carcinoma: A Propensity Score–Matched Study of 1,008 Patients

PurposeTo assess the effectiveness of transarterial bland embolization (TAE) compared with transarterial chemoembolization (TACE) therapy in the treatment of patients with intermediate-stage hepatocellular carcinoma (HCC). Materials and MethodsTwo thousand two hundred ninety-seven patients with intermediate-stage HCC were screened, and 1,461 patients who underwent TAE or TACE as the first-choice treatment were retrospectively analyzed and baseline matched according to the 2 treatment methods. Subgroup analysis was performed among patients according to the Up-to-7 criteria. The primary endpoint was overall survival (OS). ResultsA total of 1,461 patients with HCC who underwent TAE or TACE were included; 730 patients underwent TACE and 731 underwent TAE. The patients in the TAE group exhibited poorer liver function and a significantly higher rate of hepatitis B infection (P < .001) compared with the TACE group. After propensity score matching, 504 well-matched pairs of patients with intermediate-stage HCC were selected for analysis. Univariate analysis showed that TACE significantly prolonged patient survival compared with TAE (P < .001). The 1-, 2-, and 3-year OS rates were 74.3%, 57.1%, and 44.4% and for the TACE group and 58.3%, 32.4%, and 21.7% for the TAE group, respectively. Multivariate analysis showed a hazard ratio of 0.517 (95% CI, 0.442–0.605; P < .001) for the TACE approach over the TAE approach for OS. The TACE group had a significantly higher overall response rate than the TAE group (35% vs 26%; P = .024). ConclusionsTACE resulted in higher response rate and longer OS compared with TAE as the initial treatment for intermediate-stage HCC.

Importance of early detection of esophageal cancer before the tumor progresses too much for effective treatment

This editorial comments on an article by Qu et al published in the World Journal of Gastrointestinal Oncology . It focuses on the importance of early detection of esophageal cancer, including recurrence or secondary malignancy after chemoradiotherapy (CRT). Endoscopic resection is the first choice for treatment for esophageal cancer remaining within the mucous membrane, while surgery or radical CRT are treatment options for advanced stages depending on the patient’s general condition and desire. Although these treatments are potentially curative, they are more invasive than endoscopic resection. Early-stage esophageal cancer is often asymptomatic and difficult to detect. Uniform periodic endoscopy is unrealistic. Although less burdensome tests exist, including liquid biopsy and urinary biomarkers, these have not yet been widely used in clinical practice. Early detection is important after radical CRT because the local recurrence rate is higher than that after surgery. However, endoscopic resection or photodynamic therapy is indicated if detected in the early stages, and positive results have been reported. Early detection of esophageal cancer is crucial. Endoscopy is the main diagnostic method; however, new and less burdensome methods should be established to ensure early treatment for patients with esophageal cancer.

Endoscopic ultrasound-guided entero-colostomy with lumen-apposing metal stent as a rescue treatment for malignant intestinal occlusion: a multicenter study.

Surgery is the first-choice treatment for malignant intestinal obstruction (MIO); however, many patients are deemed unfit for surgery. Endoscopic ultrasound-guided entero-colostomy (EUS-EC) with a lumen-apposing metal stent (LAMS) could represent a new treatment option. Consecutive patients undergoing EUS-EC for MIO from November 2021 to September 2023 at four European tertiary referral centers were retrospectively enrolled. Multidisciplinary meetings determined whether patients were unsuitable for surgery or colonic stent placement, or refused surgery. The primary outcome was technical success of EUS-EC and secondary outcomes were clinical outcome, safety, and hospital stay. 12 patients were enrolled (median age 72.5 [range 42-85] years; 58.3% female). Colonic adenocarcinoma was the primary tumor in 75.0% of patients and 91.7% had stage IV disease. Technical success was 100%. No LAMS misdeployment or other procedural adverse events occurred; three patients (25.0%) had severe post-procedural complications. Clinical success was achieved in 10 patients (83.3%), with 5 (50.0%) resuming chemotherapy after the procedure. Median post-procedural hospital stay was 9 (1-20) days and median overall survival was 47.5 (2-270) days. EUS-EC was a feasible technique and could be considered a possible alternative to standard approaches for MIO in highly selected patients.

Factors associated with incomplete tuberculosis preventive treatment: a retrospective analysis of six-years programmatic data in Cambodia

Tuberculosis (TB) preventive treatment (TPT) effectively prevents the progression from TB infection to TB disease. This study explores factors associated with TPT non-completion in Cambodia using 6-years programmatic data (2018–2023) retrieved from the TB Management Information System (TB-MIS). Out of 14,262 individuals with latent TB infection (LTBI) initiated with TPT, 299 (2.1%) did not complete the treatment. Individuals aged between 15–24 and 25–34 years old were more likely to not complete the treatment compared to those aged < 5 years old, with aOR = 1.7, p = 0.034 and aOR = 2.1, p = 0.003, respectively. Individuals initiated with 3-month daily Rifampicin and Isoniazid (3RH) or with 6-month daily Isoniazid (6H) were more likely to not complete the treatment compared to those initiated with 3-month weekly Isoniazid and Rifapentine (3HP), with aOR = 2.6, p < 0.001 and aOR = 7, p < 0.001, respectively. Those who began TPT at referral hospitals were nearly twice as likely to not complete the treatment compared to those who started the treatment at health centers (aOR = 1.95, p = 0.003). To improve TPT completion, strengthen the treatment follow-up among those aged between 15 and 34 years old and initiated TPT at referral hospitals should be prioritized. The national TB program should consider 3HP the first choice of treatment.

Application of folded flap in laryngeal and hypopharyngeal function reconstructions after surgery of piriform sinus cancer

Objective: To investigate the use of folded flap for repair of laryngeal and hypopharyngeal defect and the clinical efficacies of laryngeal and hypopharyngeal function reconstructions after surgery of piriform sinus cancer. Methods: A retrospective analysis was performed for 10 cases of piriform sinus cancer that were treated in the Second Norman Bethune Hospital of Jilin University from January 2020 to April 2023 and all patients were males, aged 42-68 years. The first choice of treatment for all patients was surgery. After function neck dissection and tracheotomy, partial laryngectomy and hypopharyngectomy were carried out. The folded island flaps were prepared and used for the repairs of laryngeal and hypopharyngeal defects and the reconstructions laryngeal and hypopharyngeal functions. The patients were followed up. Results: The laryngeal and pharyngeal cavities were reconstructed well in 10 patients, and all the flaps survived, with no case of pharyngeal fistula. All patients were able to eat normally through the mouth at 2 weeks after surgery without obvious choking, and 4 patients completed the swallowing function evaluation without aspiration or only a small amount of aspiration. All the 10 patients underwent postoperative radiotherapy. The postoperative follow-up time was 5.4-41.4 months, and there was no case with tumor recurrence or death. Laryngoscopy showed that 8 patients had a spacious new laryngeal orifice, which met the conditions for extubation, of whom 7 patients had their tracheal tubes removed and 1 patient was still under observation, and that 2 patients had a slightly narrowed new laryngeal orifice due to a thick skin flap, with further follow-up observation. All patients retained their phonatory functions after surgery. Conclusion: Folded island flap can be used for the function reconstructions of the larynx and hypopharynx after surgery of pyriform sinus cancer.
