The utility of dynamic contrast-enhanced intranodal magnetic resonance lymphangiography (MRL) in the investigation of primary lymphatic anomalies. Clin Radiol 2024; 79:e1180-e1188. [PMID: 39003166 DOI: 10.1016/j.crad.2024.06.009] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/24/2024] [Revised: 05/18/2024] [Accepted: 06/01/2024] [Indexed: 07/15/2024]
Abstract
AIM The aim of this study was to describe the technique of DCMRL to identify central lymphatic abnormalities in patients with primary lymphatic anomalies and discuss utility of the findings. MATERIALS AND METHODS Twenty-eight patients with primary lymphatic abnormalities underwent dynamic magnetic resonance imaging (MRI) following injection of gadolinium directly into inguinal lymph nodes at a tertiary lymphovascular referral center. RESULTS Technical success was achieved in 23 patients (82.1%). Pathological imaging findings included obstructed, hypoplastic, or absent lymphatic channels with collateralization/rerouting or reflux of flow, lymphangiectasia, lymphatic pseudoaneurysms, and lymph leaks. Protocol modifications for improved imaging are highlighted including technical aspects of lymph node injection, image acquisition and MRI parameters. In two patients, imaging findings warranted embolization of the abnormal lymphatic channels with subsequent symptomatic improvement. CONCLUSION DCMRL has been shown to be a safe, reproducible technique in patients with primary lymphatic anomalies enabling imaging of the central lymphatic system.

Abstract
This work explores the effects of solvent polarity on Janus Green B (JGB) photophysical properties. The Lippert-Mataga, Billot, and Ravi equations were utilized to calculate the singlet-state excited dipole moments (µe) and ground state dipole moments (µg) using absorption and fluorescence spectra analyses. The results showed an increase in the former, which is suggestive of electronic structural alterations upon excitation. Analysis of fluorescence quantum yield values revealed that JGB's environment had an impact on its emission characteristics; it was particularly sensitive to silver nanoparticles, suggesting possible interactions. While simulations of electron density, electrostatic potential, and energy gap (Eg) helped to understand the electronic structure of JGB, theoretical absorption spectra produced by Time Dependent Density Function Theory (TD-DFT) calculations offered insights into electronic transitions during absorption. To sum up, the present study contributes to our comprehension of the molecular behavior of JGB in various solvents by elucidating the intricate relationship among solvent polarity, molecular environment, and interactions with silver nanoparticles. Additionally, theoretical computations support the interpretation of experimental results.

Abstract
OBJECTIVES Evidence on non-communicable disease (NCD) prevalence and associated risk factors informs primary health care consolidation regarding prevention and treatment strategies. In Lebanon, the government and many international organisations are still working to decrease the burden of NCDs. The aim of this study was to assess the prevalence of selected NCDs and their risk factors among adults in Lebanon, and to investigate the relationship between these risk factors and NCDs. STUDY DESIGN A multicentric cross-sectional study was conducted over one year, from 1 June 2022 to 31 June 2023, across five Lebanese governorates. METHODS Participants aged ≥18 years were considered eligible for enrolment in the study. Data on the sociodemographic, behavioural and medical characteristics of participants were collected. RESULTS From the total study population (n = 4540), 52.4% reported one or more NCDs. The prevalence of most prominent NCDs were hypertension (32.8%), diabetes (26.8%), cardiovascular disease (16.1%), asthma (7.1%) and cancer (3.7%). Results showed a significant association between gender and smoking, high-fibre diet and asthma (P-value <0.05). Findings showed a highly significant association between age categories and smoking, high-fibre diet, physical activity, diagnosis with NCDs, hypertension, diabetes and cardiovascular disease (P-value <0.0001). CONCLUSIONS This study showed a high prevalence of NCDs among adults living in Lebanon. Prevention, treatment and control of NCDs and their risk factors are a public health priority in Lebanon, and resources are required to provide targeted interventions with a multisectoral approach.

Abstract
The perovskite solar cells (PSCs) are still facing the two main challenges of stability and scalability to meet the requirements for their potential commercialization. Therefore, developing a uniform, efficient, high quality and cost-effective electron transport layer (ETL) thin film to achieve a stable PSC is one of the key factors to address these main issues. Magnetron sputtering deposition has been widely used for its high quality thin film deposition as well as its ability to deposit films uniformly on large area at the industrial scale. In this work, we report on the composition, structural, chemical state, and electronic properties of moderate temperature radio frequency (RF) sputtered SnO2. Ar and O2 are employed as plasma-sputtering and reactive gases, respectively. We demonstrate the possibility to grow a high quality and stable SnO2 thin films with high transport properties by reactive RF magnetron sputtering. Our findings show that PSC devices based on the sputtered SnO2 ETL have reached a power conversion efficiency up to 17.10% and an average operational lifetime over 200 h. These uniform sputtered SnO2 thin films with improved characteristics are promising for large photovoltaic modules and advanced optoelectronic devices.

Abstract
Background In this study we aimed to assess and compare the rate of sem-irigid ureterorenoscope in the treatment of upper and lower ureter stones through pneumatic lithotripsy (PL). Materials and Methods Ninety-two patients with a mean age±SD of 45±15years who had had a surgical procedure performed by the same experienced surgeon between January 2013 and July 2015 were included in the study. The mean±SD stone size was 8.8±2.6 mm. Forty-two of the patients (45.7%) had upper ureter stones and 50 (54.3%) had lower ureter stones in order to increase the success rate and avoid stone migration. The medical files of the patients were reviewed regarding age, sex, stone size, stone location, success rate, complications, and presence of hydronephrosis. Success was operationally defined as the complete fragmentation of stone to very small parts that could pass or complete extraction of the stone. Results Eighty-four of the patients were stone free (91%). The success rates for patients with upper or lower ureteric stones were 93% and 90%, respectively (P=0.63). There were no complications during the operation. However, 4 patients (4.4%) had postoperative complications in terms of urinary tract infection or urosepsis. Those were accurately managed by the suitable medical treatment. Conclusion Semi-rigid ureterorenoscopy by using PL was a safe and practical treatment option for managing the upper and lower ureter stones. Performing the tips and tricks of ureterorenoscopy by an experienced surgeon seems to enhance the success rate, especially in upper ureter stones.

Abstract
In the present work, we report on the microstructural and optoelectronic properties of SnOx thin films deposited by a reactive radio frequency magnetron sputtering. After SnOx growth by sputtering under O2/Ar flow, we have used three different treatment methods, namely (1) as deposited films under O2/Ar, (2) vacuum annealed films ex-situ, and (3) air annealed films ex-situ. Effects of the O2/Ar ratios and the growth temperature were investigated for each treatment method. We have thoroughly investigated the structural, optical, electrical and morphology of the different films by several advanced techniques. The best compromise between electrical conductivity and optical transmission for the use of these SnOx films as an n-type TCO was the conditions O2/Ar = 1.5% during the growth process, at 250 °C, followed by a vacuum post thermal annealing performed at 5 × 10–4 Torr. Our results pointed out clear correlations between the growth conditions, the microstructural and optoelectronic properties, where highly electrically conductive films were found to be associated to larger grains size microstructure. Effects of O2/Ar flow and the thermal annealing process were also analysed and discussed thoroughly.

Abstract
OBJECTIVE Studies have shown that prenatal exome sequencing (PES) improves diagnostic yield in cases of fetal structural malformation. We have retrospectively analysed PES cases from two of the largest fetal medicine centres in the UK to determine the impact of results on management of a pregnancy. DESIGN A retrospective review of clinical case notes. SETTING Two tertiary fetal medicine centres. POPULATION Pregnancies with fetal structural abnormalities referred to clinical genetics via a multidisciplinary team. METHODS We retrospectively reviewed the notes of all patients who had undergone PES. DNA samples were obtained via chorionic villus sampling or amniocentesis. Variants were filtered using patient-specific panels and interpreted using American College of Medical Genetics guidelines. RESULTS A molecular diagnosis was made in 42% (18/43) ongoing pregnancies; of this group, there was a significant management implication in 44% (8/18). A positive result contributed to the decision to terminate a pregnancy in 16% (7/43) of cases. A negative result had a significant impact on management in two cases by affirming the decision to continue pregnancy. CONCLUSIONS We demonstrate that the results of PES can inform pregnancy management. Challenges include variant interpretation with limited phenotype information. These results emphasise the importance of the MDT and collecting phenotype and variant data. As this testing is soon to be widely available, we should look to move beyond diagnostic yield as a measure of the value of PES. TWEETABLE ABSTRACT Prenatal exome sequencing can aid decision-making in pregnancy management; review ahead of routine implementation in NHS.

Abstract
OBJECTIVE Fetal hydrops is associated with increased perinatal morbidity and mortality. The etiology and outcome of fetal hydrops may differ according to the gestational age at diagnosis. The aim of this study was to evaluate the cause, evolution and outcome of non-immune fetal hydrops (NIFH), according to the gestational age at diagnosis. METHODS This was a retrospective cohort study of all singleton pregnancies complicated by NIFH, at the Fetal Medicine Unit at St George's University Hospital, London, UK, between 2000 and 2018. All fetuses had detailed anomaly and cardiac ultrasound scans, karyotyping and infection screening. Prenatal diagnostic and therapeutic intervention, gestational age at diagnosis and delivery, as well as pregnancy outcome, were recorded. Regression analysis was used to test for potential association between possible risk factors and perinatal mortality. RESULTS We included 273 fetuses with NIFH. The etiology of the condition varied significantly in the three trimesters. Excluding 30 women who declined invasive testing, the cause of NIFH was defined as unknown in 62 of the remaining 243 cases (25.5%). Chromosomal aneuploidy was the most common cause of NIFH in the first trimester. It continued to be a significant etiologic factor in the second trimester, along with congenital infection. In the third trimester, the most common etiology was cardiovascular abnormality. Among the 152 (55.7%) women continuing the pregnancy, 48 (31.6%) underwent fetal intervention, including the insertion of pleuroamniotic shunts, fetal blood transfusion and thoracentesis. Fetal intervention was associated significantly with lower perinatal mortality (odds ratio (OR), 0.30 (95% CI, 0.14-0.61); P < 0.001); this association remained significant after excluding cases with a diagnosis of anemia or infection (OR, 0.29 (95% CI, 0.13-0.66); P = 0.003). In 104 fetuses not undergoing active fetal intervention, the gestational age at diagnosis was the only parameter that was significantly associated with the risk of perinatal mortality (OR, 0.92 (95% CI, 0.85-0.99); P = 0.035), while the affected body cavity and polyhydramnios were not (P > 0.05). CONCLUSIONS An earlier gestational age at diagnosis of NIFH was associated with an increased risk of aneuploidy and worse pregnancy outcome, including a higher risk of perinatal loss. Fetal therapy was associated significantly with lower perinatal mortality. © 2020 Authors.
