We evaluated a protocolized endoscopic necrosectomy approach with a lumen-apposing metal stent (LAMS) in patients with large symptomatic walled-off pancreatic necrosis (WON) comprising significant necrotic content, with or without infection.Randomized trials have shown similar efficacy of endoscopic treatment compared to surgery for infected WON.We conducted a regulatory, prospective, multicenter single-arm clinical trial examining the efficacy and safety of endoscopic ultrasound (EUS)-guided LAMS with protocolized necrosectomy to treat symptomatic WON ≥ 6 cm in diameter with 30% solid necrosis. After LAMS placement, protocolized WON assessment was conducted and endoscopic necrosectomy was performed for insufficient WON size reduction and persistent symptoms. Patients with radiographic WON resolution to ≤ 3 cm and/or 60-day LAMS indwell had LAMS removal, then 6-month follow-up. Primary endpoints were probability of radiographic resolution by 60 days and procedure-related serious adverse events (SAEs).Forty consecutive patients were enrolled September 2018 - March 2020, of whom 27 (67.5%) were inpatients and 19 (47.5%) had clinical evidence of infection at their index procedure. Mean WON size was 15.0 ± 5.6 cm with mean 53.2% ± 16.7% solid necrosis. Radiographic WON resolution was seen in 97.5% (95% CI, 86.8%, 99.9%) by 60 days, without recurrence in 34 patients with 6-month follow-up data. Mean time to radiographic WON resolution was 34.1 ± 16.8 days. SAEs occurred in 3 patients (7.5%), including sepsis, vancomycin-resistant enterococcal bacteremia and shock, and upper gastrointestinal bleeding. There were no procedure-related deaths.EUS-guided drainage with protocolized endoscopic necrosectomy to treat large symptomatic or infected walled-off necrotic pancreatic collections was highly effective and safe.

Although most jurisdictions allow stereoscopically deficient and monocular individuals to drive, studies regarding these visual components' effects on driving have to date yielded contradicting results. Interviews, record reviews, and experiments have been used to unmask these effects. In interviews, participants with amblyopia reported several difficulties operating automobiles. Record reviews yielded mixed results, with studies revealing an increased crash rate and/or severity in a group of stereoscopically deficient commercial drivers, whereas studies of non-commercial drivers failed to make that association. Furthermore, experimental studies showed that individuals with reduced stereopsis braked earlier and were less likely to crash. With regard to monocularity, real-life experiments failed to demonstrate a poorer driving performance and simulation studies showed that drivers with sudden monocularity were more likely to crash and drive off the road.

Endoscopic ultrasound has evolved over the last decade from a purely diagnostic procedure into one with a rapidly growing list of therapeutic applications. One such evolution is the emergence of EUS-guided liver biopsy, which is currently considered a very safe and effective alternative to the traditional percutaneous and transjugular liver sampling techniques. EUS-guided liver biopsies allow for acquisition of liver tissue for a wide variety of indications and could have a dramatic impact on the management of patients with acute and chronic liver disorders. EUS-guided liver biopsy offers several advantages over the current standard of care techniques and appears to be associated with fewer contraindications and adverse events. There is a growing body of literature endorsing its efficacy by demonstrating comparable diagnostic yield to the percutaneous and transjugular methods. Improving diagnostic yield of EUS-guided liver biopsies remains a priority and hence, over the last decade, several needle types with enhanced tip designs have been introduced, and various tissue acquisition methods have been explored and modified to enhance the integrity of the liver specimen. This review covers the body of data on the efficacy and safety of EUS-guided liver biopsies. We closely examine the existing data on the diagnostic yield of the various needle types, tip designs and tissue acquisition techniques, and discuss proposals to enhance the adoption of EUS-guided liver biopsy across healthcare institutions.

This structure, critical in human development, enables mobility of the developing fetus within the gestational sac in contrast to the placenta, which is anchored to the uterine wall. The umbilical cord is protected by unique, robust anatomical features, which include: length of the umbilical cord, Wharton’s jelly, two umbilical arteries, coiling, and suspension in amniotic fluid. These features all contribute to protect and buffer this essential structure from potential detrimental twisting, shearing, torsion, and compression forces throughout gestation, and specifically during labor and delivery. The arterial components of the umbilical cord are further protected by the presence of Hyrtl’s anastomosis between the two respective umbilical arteries. Abnormalities of the umbilical cord are uncommon yet include excessively long or short cords, hyper or hypocoiling, cysts, single umbilical artery, supernumerary vessels, rarely an absent umbilical cord, stricture, furcate and velamentous insertions (including vasa previa), umbilical vein and arterial thrombosis, umbilical artery aneurysm, hematomas, and tumors (including hemangioma angiomyxoma and teratoma). This commentary will address current perspectives of prenatal sonography of the umbilical cord, including structural anomalies and the potential impact of future imaging technologies.Keywords: prenatal ultrasound, umbilical cord, color Doppler imaging

INTRODUCTION: Pancreatic cysts are incidentally detected in up to 13% of patients undergoing radiographic imaging. Of the most frequently encountered types, mucin-producing (mucinous) pancreatic cystic lesions may develop into pancreatic cancer, while non-mucinous ones have little or no malignant potential. Accurate preoperative diagnosis is critical for optimal management but has been difficult to achieve, resulting in unnecessary major surgery. Here, we aim to develop an algorithm based upon biomarker risk scores to improve risk stratification. METHODS: Patients undergoing surgery and/or surveillance for a pancreatic cystic lesion with diagnostic imaging and banked pancreatic cyst fluid were enrolled in the study following informed consent (n=163 surgical, 67 surveillance). Cyst fluid biomarkers with high specificity for distinguishing non-mucinous from mucinous pancreatic cysts (vascular endothelial growth factor [VEGF], glucose, carcinoembryonic antigen [CEA], amylase, cytology, and DNA mutation) were selected. Biomarker risk scores were used to design an algorithm to predict preoperative diagnosis. Performance was tested using surgical (retrospective) and surveillance (prospective) cohorts. RESULTS: In the surgical cohort, the biomarker algorithm outperformed the preoperative clinical diagnosis in correctly predicting the final pathological diagnosis (91% vs. 73%; P

BACKGROUND Megacystis-microcolon-intestinal hypoperistalsis syndrome (MMIHS) is a lethal congenital disorder characterized by a large, non-obstructed bladder, microcolon, and lack of proper peristalsis. MATERIALS AND METHODS Five cases of MMIHS were identified, confirmed histologically and were predominantly female (F:M, 4:1). DNA sequencing was also performed. RESULTS Four cases showed mutations in the α3 and β4 nicotinic acetylcholine receptor (ηAChR) subunits (CHRNA3 and CHRNB4, respectively) on chromosome 15q24. The 5th case had a delayed clinical presentation of intussusception at 11 months and showed a novel missense mutation in ATP2B4 on Chromosome 1q32. CONCLUSION The first four patients showed a previously identified mutation. The 5th patient shows a novel mutation in ATP2B4. This novel gene was associated with a less severe presentation and increases success of multiorgan transplant than the other four patients. This highlights how identifying various mutations may impact prognosis and clinical treatment plans for MMIHS patients.

Disorders of fluid balance and electrolyte homeostasis are commonly observed in critically ill patients and in those who require emergency anaesthesia. Consequently, anaesthetists and intensive care physicians must understand the physiological principles that govern fluid balance. This article discusses the compartmentalization of total body water and describes methods by which the volume of the fluid compartments may be measured. The novel concept of the endothelial glycocalyx is discussed in addition to the conventional and contemporary models of capillary filtration dynamics. The core elements of fluid balance and cardiovascular homeostasis are also explored.

Overexpression and activation of matrix metalloproteinase-13 (MMP-13) within atheroma increases susceptibility to plaque rupture, a major cause of severe cardiovascular complications. In comparison to pan-MMP targeting [18F]BR-351, we evaluated the potential for [18F]FMBP, a selective PET radiotracer for MMP-13, to detect extracellular matrix (ECM) remodeling in vascular plaques possessing markers of inflammation. [18F]FMBP and [18F]BR-351 were initially assessed in vitro by incubation with en face aortae from 8 month-old atherogenic ApoE−/− mice. Ex vivo biodistributions, plasma metabolite analyses, and ex vivo autoradiography were analogously performed 30 min after intravenous radiotracer administration in age-matched C57Bl/6 and ApoE−/− mice under baseline or homologous blocking conditions. En face aortae were subsequently stained with Oil Red O (ORO), sectioned, and subject to immunofluorescence staining for Mac-2 and MMP-13. High-resolution autoradiographic image analysis demonstrated target specificity and regional concordance to lipid-rich lesions. Biodistribution studies revealed hepatobiliary excretion, low accumulation of radioactivity in non-excretory organs, and few differences between strains and conditions in non-target organs. Plasma metabolite analyses uncovered that [18F]FMBP exhibited excellent in vivo stability (≥74% intact) while [18F]BR-351 was extensively metabolized (≤37% intact). Ex vivo autoradiography and histology of en face aortae revealed that [18F]FMBP, relative to [18F]BR-351, exhibited 2.9-fold greater lesion uptake, substantial specific binding (68%), and improved sensitivity to atherosclerotic tissue (2.9-fold vs 2.1-fold). Immunofluorescent staining of aortic en face cross sections demonstrated elevated Mac-2 and MMP-13-positive areas within atherosclerotic lesions identified by [18F]FMBP ex vivo autoradiography. While both radiotracers successfully identified atherosclerotic plaques, [18F]FMBP showed superior specificity and sensitivity for lesions possessing features of destructive plaque remodeling. The detection of ECM remodeling by selective targeting of MMP-13 may enable characterization of high-risk atherosclerosis featuring elevated collagenase activity.

In current research, we aimed to investigate the chemical composition of the EO of Erica manipuliflora extracted in two growth periods (before flowering and full flowering periods), to evaluate the differences between the two EOs in antibacterial activity against four pathogenic bacteria (Bacillus subtilis, Staphylococcus aureus, Escherichia coli and Salmonella enteritidis). Results showed the existence of 17 and 23 volatile components in the EOs extracted from E. manipuliflora before flowering and in full flowering periods, respectively. The main components in EO extracted from the plant before flowering period were Germacrene-D, tau-cadinol, β-caryophellene, Trans-pinocarveol and β-pinene; which represented 35.02, 26.36, 14.78, 9.25 and 3.65%, respectively. The EO extracted from the plant collected in full flowering period were β-citral, β-pinene, Germacrene-D, tau-cadinol and Trans-pinocarveol, which represented 22.26, 18.50, 16.90, 11.89 and 5.58%, respectively. The EO extracted from E. manipuliflora in the full flowering period was more active than that extracted before flowering period towards the bacterial species mentioned above. The most sensitive bacterium towards E. manipuliflora EOs was Bacillus subtilis, while the most resistant one was Salmonella enteritidis.

Objectives Chest CT has been widely used to screen and to evaluate the severity of COVID-19 disease in the early stages of infection without severe acute respiratory syndrome, but no prospective data are available to study the relationship between extent of lung damage and short-term mortality. The objective was to evaluate association between standardized simple visual lung damage CT score (vldCTs) at admission, which does not require any software, and 30-day mortality. Methods In a single-center prospective cohort of COVID-19 patients included during 4 weeks, the presence and extent of ground glass opacities(GGO), consolidation opacities, or both of them were visually assessed in each of the 5 lung lobes (score from 0 to 4 per lobe depending on the percentage and out of 20 per patient = vldCTs) after the first chest CT performed to detect COVID-19 pneumonia. Results Among 210 confirmed COVID-19 patients, the number of survivors and non-survivors was 162 (77%) and 48 (23%), respectively at 30 days. vldCTs was significantly higher in non-survivors, and the AUC of vldCTs to distinguish survivors and non-survivors was 0.72 (95%CI 0.628–0.807, p < 0.001); the best cut-off vldCTs value was 7. During follow-up, significant differences in discharges and 30-day mortality were observed between patients with vldCTs ≥ 7 versus vldCTs < 7: (98 [85.2%] vs 49 [51.6%]; p < 0.001 and 36 [37.9%] vs 12 [12.4%]; p < 0.001, respectively. The 30-day mortality increased if vldCTs ≥ 7 (HR, 3.16 (1.50–6.43); p = 0.001), independent of age, respiratory rate and oxygen saturation levels, and comorbidities at admission. Conclusions By using chest CT in COVID-19 patients, extensive lung damage can be visually assessed with a score related to 30-day mortality independent of conventional risk factors of the disease. Key Points • In non-selected COVID-19 patients included prospectively during 4 weeks, the extent of ground glass opacities(GGO) and consolidation opacities evaluated by a simple visual score was related to 30-day mortality independent of age, respiratory rate, oxygen saturation levels, comorbidities, and hs-troponin I level at admission. • This severity score should be incorporated into risk stratification algorithms and in structured chest CT reports requiring a standardized reading by radiologists in case of COVID-19.

Background Subsequent epidemic waves have already emerged in many countries and in the absence of highly effective preventive and curative options, the role of patient characteristics on the development of outcomes needs to be thoroughly examined, especially in middle-east countries where such epidemiological studies are lacking. There is a huge pressure on the hospital services and in particular, on the Intensive Care Units (ICU). Describing the need for critical care as well as the chance of being discharged from hospital according to patient characteristics, is essential for a more efficient hospital management. The objective of this study is to describe the probabilities of admission to the ICU and the probabilities of hospital discharge among positive COVID-19 patients according to demographics and comorbidities recorded at hospital admission. Methods A prospective cohort study of all patients with COVID-19 found in the Electronic Medical Records of Jaber Al-Ahmad Al-Sabah Hospital in Kuwait was conducted. The study included 3995 individuals (symptomatic and asymptomatic) of all ages who tested positive from February 24th to May 27th, 2020, out of which 315 were treated in the ICU and 3619 were discharged including those who were transferred to a different healthcare unit without having previously entered the ICU. A competing risk analysis considering two events, namely, ICU admission and hospital discharge using flexible hazard models was performed to describe the association between event-specific probabilities and patient characteristics. Results Results showed that being male, increasing age and comorbidities such as chronic kidney disease (CKD), asthma or chronic obstructive pulmonary disease and weakened immune system increased the risk of ICU admission within 10 days of entering the hospital. CKD and weakened immune system decreased the probabilities of discharge in both females and males however, the age-related pattern differed by gender. Diabetes, which was the most prevalent comorbid condition, had only a moderate impact on both probabilities (18% overall) in contrast to CKD which had the largest effect, but presented only in 7% of those admitted to ICU and in 1% of those who got discharged. For instance, within 5 days a 50-year-old male had 19% (95% C.I.: [15,23]) probability of entering the ICU if he had none of these comorbidities, yet this risk jumped to 31% (95% C.I.: [20,46]) if he had also CKD, and to 27% in the presence of asthma/COPD (95% C.I.: [19,36]) or of weakened immune system (95% C.I.: [16,42]). Conclusions This study provides useful insight in describing the probabilities of ICU admission and hospital discharge according to age, gender, and comorbidities among confirmed COVID-19 cases in Kuwait. A web-tool is also provided to allow the user to estimate these probabilities for any combination of these covariates. These probabilities enable deeper understanding of the hospital demand according to patient characteristics which is essential to hospital management and useful for developing a vaccination strategy.

Background: Loss of mismatch repair (MMR) occurs frequently in endometrial carcinoma (EC) and is an important prognostic marker. However, the frequency of MMR deficiency (D-MMR) in EC remains inconclusive. This systematic review and meta-analysis addressed this inconsistency and evaluated related clinicopathology. Materials and Methods: Electronic databases were searched for articles: PubMed, Science Direct, Web of Science, EMBASE, and the Wiley Online Library. Data were extracted from 25 EC studies of D-MMR to generate a clinical dataset of 7,459 patients. A random-effects model produced pooled estimates of D-MMR EC frequency with 95% confidence interval (CI) for meta-analysis. Results: The overall pooled proportion of D-MMR was 24.477% (95% CI, 21.022 to 28.106) in EC. The Lynch syndrome subgroup had 22.907% pooled D-MMR (95% CI, 14.852 to 32.116). D-MMR was highest in type I EC (25.810) (95% CI, 22.503 to 29.261) compared to type II (13.736) (95% CI, 8.392 to 20.144). Pooled D-MMR was highest at EC stage and grades I-II (79.430% and 65.718%, respectively) and lowest in stages III-IV and grade III (20.168% and 21.529%). The pooled odd ratios comparing D-MMR to proficient MMR favored low-stage EC disease (1.565; 0.894 to 2.740), lymphovascular invasion (1.765; 1.293 to 2.409), and myometrial invasion >50% (1.271; 0.871 to 1.853). Conclusion: Almost one-quarter of EC patients present with D-MMR tumors. The majority has less aggressive endometrioid histology. D-MMR presents at lower tumor stages compared to MMR-proficient cases in EC. However other metastatic parameters are comparatively higher in the D-MMR disease setting.

Women’s contributions to the medical field have increased substantially over the past 4 decades but women remain underrepresented. Since research productivity is an important criterion for promotion, it was essential to assess the gender differences within the faculty of medicine and across departments. We conducted a bibliometric analysis using the Scopus database between 2009 and 2018 at the American University of Beirut (N = 324, 93 women, 231 men). Women comprised 29% of the faculty. The rank of Professor was held by 34% of men and 18% of women (p

Background ABO blood groups have been linked to susceptibility to infection with certain microorganisms, including coronaviruses. We examined the relationship between blood group and clinical outcomes in individuals infected with severe acute respiratory syndrome coronavirus‐2 (SARS‐CoV‐2) and compared their blood group distribution with the general population. Methods At the inception of the pandemic, all individuals testing positive for SARS‐CoV‐2 in Kuwait were admitted to one designated coronavirus disease 2019 (COVID‐19) hospital and enrolled in a prospective registry. Patients admitted from February 24 to May 27, 2020, were stratified according to blood group. As a control, blood groups of 3,730,027 anonymized individuals representing almost Kuwait's entire population were obtained from a national database. Results Of 3305 SARS‐CoV‐2–positive patients, 37.1%, 25.5%, 28.9%, and 8.5% were groups O, A, B, and AB, respectively. Univariate analysis revealed no significant differences in severe clinical outcomes or death among the blood groups. However, multivariable analysis demonstrated that group A individuals had higher odds of developing pneumonia compared with non–group A (adjusted odds ratio 1.32, 95% confidence interval 1.02–1.72, p

This review aims to explore the burden of hypertension among refugees in the Middle East by reporting its prevalence, risk factors and access to care. A comprehensive literature search was performed using Web of Science, Ovid MEDLINE, PubMed, SCOPUS, CINHAL+, WHO Regional Office for the Eastern Mediterranean (EMRO) and United Nations High Commissioner for Refugees (UNHCR) on articles spanning from 1948 until 2020. Most studies were cross-sectional in design. After applying eligibility criteria 17 articles and 4 reports were included. Findings showed that hypertension represents a major burden among refugees. Hypertension risk factors present among the refugee population included increased salt intake, physical inactivity, and smoking. The majority of hypertensive refugees sought care for their condition at the public health care services. Barriers to seeking care included high cost of healthcare, accessibility to provided services, and lack of knowledge for the need to seek care. Non-adherence to medication among refugees was primarily linked to cost and lack of symptoms. This review highlights the need for further studies to shed light on the importance of targeting hypertension among refugees, to lower morbidity and mortality, in addition to providing adequate healthcare services to this population.

Purpose This study aims to investigate the influencers’ credibility dimensions (i.e. attractiveness, trustworthiness, expertise) on purchase intention (PI) through the mediating role of cognitive and affective online engagement among the aesthetic dermatology consumers in Jordan. Design/methodology/approach The population of this study entails all followers of aesthetic dermatology clinics on their Instagram accounts. However, only three influencers from the aesthetic dermatology industry were selected and approved the request of sharing the survey instrument on their official platforms. Overall, 600 surveys were distributed, but only 384 were completed fully, constituting a 64% response rate. Findings The data analysis revealed an excellent fit for the data and indicated an impact of attractiveness and expertise on online engagement and PI. Moreover, a mediating influence was also found for online engagement on the path between influencer credibility and PI. Research limitations/implications This study has a limitation of collecting the data from only three influencers; consequently, collecting data from the followers of more than four influencers would get more generalizable results. Second, considering further, examining the mediating role of other variables such as electronic word-of-mouth (EWOM) and loyalty programs could also provide further insights onto the nature of the factors affecting the PI. In addition, future studies should examine the differences of using more than one social media platform. Practical implications The main findings of this study have a number of managerial implications for marketing management that hint at liking the influencers who are highly trusted owing to their extensive expertise in the area they are marketing rather than only depending on their physical attractiveness. The Jordanian culture does not focus only on the image shared by the social media as the reviews can either support or decline the influence of even the celebrity. Significantly, a set of managerial implications come from the current research. Social implications Two major areas are the most important; these are the trustworthy issue and the EWOM. The marketers should encourage their customers to openly talk about their experiences as they have an imperative role in liking influencers in a way that improves their PI. The second implication is related to social media platforms management that marketing managers should resolve any negative EWOM caused and to enhance followers’ satisfaction levels of the services. The increase in satisfaction positively affects PI, and the service makes the influencer role become more effective. Originality/value This study was able to add a value to the current understanding of the main antecedents of customer engagement by looking at these dimensions of perceived credibility. Another contribution was captured in this study by successfully validating the meditating impact of customer engagement between influencers’ credibility dimensions and PI, especially in the absence of the studies that have addressed such relationship.

Color vision deficiencies are a group of vision disorders, characterized by abnormal color discrimination. They include red-green color blindness, yellow-blue color blindness and achromatopsia, among others. The deficiencies are caused by mutations in the genes coding for various components of retinal cones. Gene therapy is rising as a promising therapeutic modality. The purpose of this review article is to explore the available literature on gene therapy in the different forms of color vision deficiencies. A thorough literature review was performed on PubMed using the keywords: color vision deficiencies, gene therapy, achromatopsia and the various genes responsible for this condition (OPN1LW, OPN1MW, ATF6, CNGA3, CNGB3, GNAT2, PDE6H, and PDE6C). Various adenovirus vectors have been deployed to test the efficacy of gene therapy for achromatopsia in animals and humans. Gene therapy trials in humans and animals targeting mutations in CNGA3 have been performed, demonstrating an improvement in electroretinogram (ERG)-investigated cone cell functionality. Similar outcomes have been reported for experimental studies on other genes (CNGB3, GNAT2, M- and L-opsin). It has also been reported that delivering the genes via intravitreal rather than subretinal injections could be safer. There are currently 3 ongoing human clinical trials for the treatment of achromatopsia due to mutations in CNGB3 and CNGA3. Experimental studies and clinical trials generally showed improvement in ERG-investigated cone cell functionality and visually elicited behavior. Gene therapy is a promising novel therapeutic modality in color vision deficiencies.

Introduction Laparoscopic Sleeve Gastrectomy (LSG) is one of the most prevalent approaches to tackle obesity and its co-morbidities. The main complication following the LSG is Gastro-esophageal reflux disease (GERD), with most patients developing worsening symptoms of GERD, and a small number progressing to Barrett's esophagus. This retrospective analysis aims to assess the rate of GERD pre- and post- LSG as well as the rate of progression to Barrett's. Methods Data was collected from 1639 patients. 92 patients fit our inclusion criteria. Data was then analyzed and summarized against similar literature. Results Of 64 (69.6%) patients who had normal EGD findings pre-LSG, only 28 patients (30.4%) had the same results 5 years post-LSG (p=, Highlights • The main complication post-LSG is Gastro-esophageal reflux disease (GERD), with some progressing to Barrett’s esophagus. • We assessed Esophagogastroduodenoscopy (EGD) results pre-LSG and 5 yrs post-op to determine the development of Barrett’s. • This paper and the included literature demonstrate that LSG does lead to the development of Barrett’s Esophagus. • Performing an EGD pre- and post-LSG is an important protocol that aids in the diagnosis and management of LSG related GERD.

Aims and objectives This study aimed at describing the characteristics and outcomes of pediatric glaucoma patients in a university hospital in Lebanon and comparing them between primary congenital glaucoma (PCG) and secondary glaucoma. Materials and methods Sixty-four eyes of 40 pediatric glaucoma patients with a follow-up of 1 year or more were reviewed. Parameters were studied for both PCG and secondary glaucoma groups. Three major outcomes were considered: intraocular pressure (IOP) control, final best-corrected visual acuity (BCVA), and the proportion of failed angle surgeries. Results Sixty-four eyes were included divided into 29 PCG and 35 secondary glaucoma eyes, followed up for a mean of 6.6 ± 4.7 years. Eyes with PCG presented earlier, with a higher initial IOP and underwent earlier surgery than their secondary glaucoma counterparts. Although 85.9% of all eyes achieved good IOP control, 44.4% of them had a BCVA ≥20/50 with PCG having a better visual prognosis. Secondary glaucoma eyes needed more medications at the end of their follow-up. In this group, it was shown that a later age at first surgery, unilateral disease, and multiple surgeries were associated with a BCVA < 20/50. Conclusion Patients with PCG presented earlier and with a higher IOP than secondary glaucoma; they were also operated on earlier. Both groups demonstrated good IOP control at the end of the follow-up period with PCG eyes having a superior visual outcome. Secondary glaucoma eyes required a higher number of medications at their final visit. In this population, multiple surgeries, unilateral disease, and a delayed first surgery conferred a poorer visual prognosis. Clinical significance Data regarding the characteristics of pediatric glaucoma, especially in the Middle East, are scarce. Our study sheds the light on the presentation of different types of pediatric glaucoma and their outcomes namely IOP control and visual acuity.

Clinical presentation of coronavirus disease‐2019 (COVID‐19) ranges from asymptomatic to severe and life‐threatening. National‐level registries found that children, generally, have less severe disease when compared with adults. However, most asymptomatically infected children will not present to hospital and may be missed. We aimed to describe the clinical characteristics in pediatric COVID‐19 patients in Kuwait, and to estimate the potential duration of viral shedding. A retrospective cohort study was performed in Jaber Alahmad Hospital (JAH) from February 29 to April 30, 2020. During the study period and as part of the public health measures, all severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2)‐infected patients from 1 month to 18 years old, regardless of symptoms, were hospitalized at JAH, and were included. Polymerase chain reaction (PCR) negativity was defined as having two consecutive negative PCR results from a respiratory specimen. Descriptive statistics and multivariable regression analyses were performed. We found that 67.9% (95% CI, 59.4%–75.3%) of 134 SARS‐CoV‐2‐infected children were asymptomatic. Median PCR positivity was 15 days and did not vary with symptoms. Among patients who had laboratory investigations and chest imaging, symptomatic infection was associated with elevated C‐reactive protein and procalcitonin, and radiographic pneumonia. Asymptomatic SARS‐CoV‐2 infection is very common in children. Among symptomatic patients, the disease seems to be mild. Children exhibit substantial duration of viral shedding, regardless of symptoms.

Diabetes mellitus (DM) is one of the challenging health problems worldwide. Primary care centers manage and treat most of DM cases. Diabetes requires ongoing, and evidence-based health care which should be provided by highly qualified physicians.This study aims at evaluating the Family Medicine training efficacy on the quality of care for diabetic patients.This is a cross-sectional study conducted among patients with DM at the AlJafer training center situated in AlAhssa, Saudi Arabia. The data of diabetic patients who were followed up initially with general practitioners (GPs) and later with family physicians (FPs) collected from the patients' electronic files. Clinical parameters including HbA1c, blood pressure, total cholesterol, LDL, and statin, aspirin initiation measured during initial visits and follow-ups to compare the quality of diabetic care between the two groups (FPs vs. GPs). All statistical analyses carried using SPSS version 21.Eighty-three patients were included in the study. Regarding the measurement process, FPs more likely to measure HbA1c twice a year than GPs (P:0.001). The number of patients with HbA1c level8% decreased significantly during the period of follow-up with FPs (P:0.001). Furthermore, a significant number of patients meet the BP target ≤130/85 during the follow-up period with FPs. The statin initiation is substantially achieved more by FPs (P 0.001).Family medicine training has a significant influence on the clinical outcomes of patients with DM. This study's findings suggest that FPs ensure a better quality of care in terms of clinical and process measures.

Background Endometrial carcinoma (EC) is classified into four distinct molecular subgroups including ultramutated DNA polymerase epsilon (POLE). POLE-mutated tumors have the best prognosis and are a promising target for immunotherapy. This meta-analysis consolidated the reported variation of POLE-mutant frequency and assessed prognostic value in EC. Methods Internet searches explored scientific data bases: EMBASE, PubMed, and the Cochrane Central Register of Controlled Trials databases. Data was extracted from eligible studies including: sample size, number of positive POLE-mutant cases, sequencing information, clinicopathologic data, and survival data. Meta-analysis and a random-effects model produced pooled estimates of POLE frequency and prognostic parameters using 95% confidence intervals (CI), hazard ratios (HR), and odd ratios (OR). Results Six thousand three hundred and forty-six EC patient cases were pooled from 25 studies. The pooled proportion of POLE gene mutation in EC was 8.59% (95% CI, 7.01 to 10.32), of which 8.22% (95% CI, 6.27 to 10.42) were type I and 0.93% (95% CI, 0.34 to 1.81) type 2. Clinicopathologic data showed that POLE-mutated tumors are mostly endometrioid. They present at higher levels in earlier stages (I-II) of EC (89.51%; 95% CI, 81.11 to 95.66) at the highest grade III (51.53%; 95% CI, 36.08 to 66.84) with reduced myometrial invasion (OR, 1.48, 95% CI, 0.99 to 2.20). Survival analysis indicated favorable overall survival (HR, 0.90), disease-specific survival (HR, 0.41), and progression-free survival (HR, 0.23) for POLE mutant EC. Conclusions Almost one-tenth of EC patients have POLE-mutated tumors. Given their improved prognostic potential, identifying the POLE mutation status is key for the management of EC patients.

Background Pancreatic mass sampling has historically been performed by endoscopic ultrasound-guided fine needle aspiration (EUS-FNA). However, its sensitivity has been reported to be within a wide range, which limits its reliability. Fine needle biopsy (FNB) has been shown to have superior diagnostic performance and is increasingly replacing fine needle aspiration. In FNA, 25 gauge (G) needles appear to outperform 22G. Data comparing these sizes in FNB platforms is limited. We aimed to prospectively compare the performance of 22G and 25G Franseen-tip core biopsy needles in the sampling of solid pancreatic lesions. Patients and methods Patients who underwent EUS-FNB of pancreatic lesions at the Indiana University Hospital using 2 needle sizes: 25G (Study group) and 22G (Control group) using the Acquire needle (Boston Scientific Co., Natick, MA, USA) were enrolled. Needle choice was left to the discretion of the endosonographer. Tissue specimens were evaluated onsite, and underwent touch and smear and cellblock preparation. Specimens were independently evaluated by 2 expert cytopathologists blinded to diagnosis. Cytopathologists assessed cytological yield (on smears) and histological yield (on cellblock) using a validated scoring system reached by a consensus among our cytopathologists as we have previously published. Results A total of 75 patients (42 males, median=65 years) underwent EUS-FNB during the study period (2017-2018): 50 using 25G and 25 using 22G needle. Diagnostic yield was numerically higher in 25G (98% vs. 88%, p=0.105). Number of passes for smears were similar, however the 25G group required additional passes for cell-block (1.6 vs. 0.4, p=0.001). 25G was used more frequently for pancreatic head and uncinate process sampling (70% vs. 52%, p=0.126). Four patients had self-limited adverse events in the 22G group, but none in the 25G group. Conclusion We report no difference in the diagnostic yield between 25G FNB vs. 22G sampling device with Franseen style tip, however, the 25G needle use was associated with the need of additional passes to collect a sufficient cell block.

Background Endoscopic ultrasound-directed transgastric endoscopic retrograde cholangiopancreatography (ERCP; EDGE) is an alternative to enteroscopy- and laparoscopy-assisted ERCP in patients with Roux-en-Y gastric bypass anatomy. Although short-term results are promising, the long-term outcomes are not known. The aims of this study were: (1) to determine the rates of long-term adverse events after EDGE, with a focus on rates of persistent gastrogastric or jejunogastric fistula; (2) to identify predictors of persistent fistula; (3) to assess the outcomes of endoscopic closure when persistent fistula is encountered. Methods This was a multicenter retrospective study involving 13 centers between February 2015 and March 2019. Adverse events were defined according to the ASGE lexicon. Persistent fistula was defined as an upper gastrointestinal series or esophagogastroduodenoscopy showing evidence of fistula. Results 178 patients (mean age 58 years, 79 % women) underwent EDGE. Technical success was achieved in 98 % of cases (175/178), with a mean procedure time of 92 minutes. Periprocedural adverse events occurred in 28 patients (15.7 %; mild 10.1 %, moderate 3.4 %, severe 2.2 %). The four severe adverse events were managed laparoscopically. Persistent fistula was diagnosed in 10 % of those sent for objective testing (9/90). Following identification of a fistula, 5 /9 patients underwent endoscopic closure procedures, which were successful in all cases. Conclusions The EDGE procedure is associated with high clinical success rates and an acceptable risk profile. Persistent fistulas after lumen-apposing stent removal are uncommon, but objective testing is recommended to identify their presence. When persistent fistulas are identified, endoscopic treatment is warranted, and should be successful in closing the fistula.

Background Secretin-induced duodenal aspiration (SIDA) of pancreatic duct fluid has been proposed for pancreatic neoplasm screening in very high-risk patients. We sought to determine the clinical yield and safety of commercially-analyzed SIDA samples in patients at moderately elevated risk. Patients and methods A prospectively maintained institutional database of pancreatic fluid DNA profiles was retrospectively reviewed. Results Fifty-seven patients underwent SIDA testing, most commonly for intraductal papillary mucinous neoplasms (n=43) and not otherwise specified solitary cysts (n=9). SIDA mutation yield was low compared to 37 concomitant endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) samples of pancreatic fluid: KRAS (2.5% vs. 40.0%), GNAS (2.6% vs. 11.1%) and allelic loss of heterozygosity (3.1% vs. 0%). Patients undergoing SIDA alone experienced no complications while 3 patients with concomitant EUS-FNA had post-procedural pancreatitis. Conclusion The genetic yield of commercially-analyzed SIDA samples was relatively low in a moderately elevated risk cohort. SIDA testing may have a better safety profile than EUS-FNA.

Objectives The yield of genetic testing of main pancreatic duct (MPD) fluid collected during endoscopic retrograde cholangiopancreatography (ERCP) versus endoscopic ultrasound-guided fine-needle aspiration is unclear. Methods Consecutive MPD fluid samples obtained by endoscopic ultrasound/ERCP with DNA profiling were reviewed, excluding specimens designated "no amplification." Invasive disease included invasive cancer or malignant cytology. Results One hundred ten samples from 109 patients who underwent ERCP (n = 32) or endoscopic ultrasound-guided fine-needle aspiration (n = 78) were analyzed (2007-2018). Leading indications were dilated MPD and suspected intraductal papillary mucinous neoplasm. Elevated DNA quantity, KRAS, loss of heterozygosity (LOH), and GNAS mutations occurred in 61.5%, 25.5%, 16.4%, and 8.7% of samples, respectively. Elevated DNA quantity occurred more frequently in ERCP samples (84.4% vs 51.9%, P = 0.002); other mutation yields were similar (P > 0.05). Invasive pathology (P = 0.032) was associated with LOH in the subset of patients who underwent surgery (n = 44). Adverse events occurred more frequently after ERCP (28.1% vs 9.0%, P = 0.016). Conclusions Endoscopic MPD fluid sampling may yield genetic data to improve diagnosis and risk stratification. In our surgical cohort, LOH was the sole predictor of invasive pathology. Endoscopic ultrasound-guided fine-needle aspiration of MPD fluid, when possible, is preferred because of superior safety profile.

Cranial fasciitis is an uncommon benign fibroblastic tumor, generally histologically identical to nodular fasciitis. It develops almost exclusively in children. Cranial fasciitis manifests clinically as a painless rapidly growing solitary nodule in the head and neck area, frequently eroding the underlying bone. Thus, this entity is often confused with aggressive lesions such as sarcomas, both clinically and radiologically. Histopathologic examination is essential to differentiate between cranial fasciitis and fibrohistiocytic or even sarcomatous lesions observed in children. In this article, we present a case of cranial fasciitis with intracranial extension in a 2-year-old boy. Although USP6 rearrangement has recently been recognized as a recurring alteration in nodular fasciitis, we present a novel COL1A1-CAMTA1 fusion in this lesion.

Data on comparative efficacy of various available endoscopic ultrasound-guided liver biopsy (EUS-LB) needles are limited. We sought to compare the performance of a novel Franseen-tip 22G fine-needle biopsy (FNB) device to that of 19G needle platforms for liver parenchyma. Consecutive patients referred for EUS and suspected to have hepatic parenchymal disease underwent EUS-LB using different EUS needles and were included in this retrospective study. Two blinded expert liver pathologists independently reviewed and reported on: total number of tissue fragments, length of longest fragment, number of complete and incomplete portal tracts (CPT and IPT), and specimen adequacy. A 22G Franseen-tip needle (A) was used in 30 patients; 19G Tru-Cut needle (B) in 50 patients; 19G reverse beveled non-Tru-Cut needle (C) in 27 patients; and a 19G flexible non-Tru-Cut needle (D) in 28 patients. In the order of needles, A, B, C and D, > 10 tissue fragments were obtained in 100%, 6%, 82%, and 96% samples, the mean number of CPTs was 6.9; 3.0; 7.3; and 16.9, length of longest fragment was 3.8, 4. 7, 3.9, and 8.4 mm, and specimen adequacy was 66.7%, 46%, 82.1%, and 81.5%, respectively. A positive correlation was obtained between number of CPTs and length of longest fragment in samples accrued by 19G needles. EUS-LB specimens using 22G Franseen-tip needle appear highly fragmented, leading to inferior specimen adequacy compared to 19G non-Tru-Cut needles. We also report on using length of longest fragment as an additional criterion for specimen adequacy as it positively correlates with number of CPTs standard.
