LOFAR Search for Radio Emission from Galaxies Hosting Tidal Disruption Events
Authors: Kaushik Kamakshi , Omar Amitesh , Kumar Brijesh , Mishra Kuntal , Joshi Jagdish 
Published: September 2022

Abstract
Radio emission from 23 tidal disruption event host galaxies were searched in the 144 MHz LOFAR-LoTSS2 images. Three host galaxies are detected with diffuse radio emission, which can be interpreted as either galactic synchrotron radio emission or diffuse radio halo in dense galactic environments. Non-detection of (transient) radio emission in majority of galaxies could be due to self-absorption of radio emission associated with the tidal disruption event.
La biodiversité et les écosystèmes à travers le temps et l’espace
Authors: Bowler Chris 
Published: September 2022

Après 4,5 milliards d’années d’évolution, notre planète s’épuise du fait de l’exploitation intensive des énergies fossiles et de l’eau, de la surconsommation d’engrais agricoles et de la déforestation. Elle pourrait vivre la plus importante des extinctions massives.
Observer les organismes avec lesquels nous cohabitons permet de mieux comprendre les fonctions de chacun et de percevoir l’ampleur des phénomènes en cours, qui engagent dès à présent l’avenir de l’humanité : perte de la biodiversité, dégradation des écosystèmes, changement climatique, épidémies. Face à ce constat alarmant, les scientifiques ont un rôle déterminant à jouer : produire des modèles et formuler des prédictions pour susciter des actions politiques concrètes.
La question de la licéité des images dans le judaïsme ancien à travers l’exemple des pavements en mosaïque de deux synagogues africaines
Authors: Villey Thomas 
Published: September 2022

L’art juif a longtemps été considéré comme un art « aniconique », c’est-à-dire comme un art dépourvu de représentations figurées animales et humaines. Pourtant, les juifs ont eu au cours de leur histoire des attitudes variées à l’égard des représentations figurées : la proscription des images n’a pas toujours été de mise, en particulier durant l’Antiquité tardive. Ces différences d’attitude découlent notamment d’une interprétation plus ou moins stricte du deuxième commandement du Décalogue, qui interdit la fabrication des images afin d’éviter l’idolâtrie. Cet article cherche à déterminer si le programme iconographique des mosaïques de pavements des synagogues d’Hammam-Lif et de Kelibia est le reflet d’une interprétation particulière de ce deuxième commandement, et, plus généralement, du type de judaïsme pratiqué dans ces communautés juives africaines durant l’Antiquité tardive. Si ces mosaïques synagogales africaines comportaient des représentations animales, elles s’abstenaient en revanche de représenter la figure humaine, ce qui les distinguaient des mosaïques de certaines synagogues palestiniennes contemporaines, où de telles images étaient licites, mais aussi des pavements en mosaïque d’un certain nombre d’églises africaines des Ve-VIe siècle, qui comportaient des représentations de la figure humaine.

Indocyanine green fluorescence video angiography – An indispensable tool for avoiding vascular complications during microsurgical clipping of ruptured intracranial aneurysms and improving surgical outcome
Authors: Acharya Ashish , Grewal Sarvpreet 
Published: September 2022

Background:
The surgical complications in aneurysmal microsurgical clipping are attributable primarily to vascular compromise and retraction injury. The vascular complications almost 50% of these. ICG-VA gives us intraoperative real-time high definition functional imaging of the cerebrovascular tree, thereby allowing immediate quality assessment and control of aneurysm obliteration and parent vessel optimisation. Here we report our preliminary data of an ongoing series of patient study.

Objective:
This study aims at evaluating the role of ICG VA in avoiding vascular complications during microsurgical clipping of ruptured intracranial aneurysms and ascertaining normative data for ICG dye administration.

Materials and Methods:
The study aimed at determining the utility of microscope incorporated (Leica M530 OHX microscope) ICG VA in ruptured aneurysm surgery. We used ICG-VA in 17 patients of ruptured aneurysm with WFNS grade 1 and 2 as an adjunct to surgery. We studied multiple patient characteristics, intraoperative ICG peak flow and washout time of dye, and changes made in the operative decisions, and outcome of the surgeries.

Results:
ICG-VA helped in intraoperative decision making for 5 out of 17 patients. In one patient, inadequate clipping with residual neck was confirmed with ICG-VA and the clip was adjusted. In three patient's perforator/additional vessel compromise was found hence needed clip readjustment, whereas in two patients ICG-VA demonstrated residual filling of large neck sac and 2nd clip was applied in tandem.

Conclusion:
ICG VA is a conclusively simple adjunctive tool for the early detection and prevention of vascular compromise of multiple vessels and perforators during ruptured aneurysm surgery.
Judicious use of temporary clipping on atheromatous vessels and avoidance of its complications in aneurysm surgery
Authors: Manoharan Ganesh Kumar , Prasad Rjvv , Kumar S Senthil 
Published: September 2022

Introduction:
Since the invention of aneurysm clipping surgery, temporary clipping of proximal vessels has been an integral part of the surgery. Temporary clipping provides adequate control of the proximal vessel and allows the surgeon to clip the aneurysm more confidently. Whereas, its complications are numerous, and one has to be very conscious in applying temporary clips, especially over the atheromatous vessels.

Methods:
A cross-sectional observational study was conducted on 50 cases of intracranial aneurysms operated at the study centre, wherein temporary clipping is used, and atheromatous proximal vessels were seen and noted. intraoperatively. Post-operative complications in these cases were noted.

Results:
The atheromatous proximal vessel as identified intraoperatively was seen in 60% of the cases. The mean age of the study population was 55.86 years. About 32% of the study population were male. The average body mass index of the study population was 24.5. 72% of the study group were hypertensive and 44% were diabetic. About 48% of patients presented with the World Federation of Neurosurgical Societies Grade 2. About 88% of the aneurysms were in the anterior circulation, with a mean size of <7 mm, and mean neck size was 4.8 mm. The average frequency of usage of temporary in each case was 3.08 times, and the longest clip used was for 8 min. The complications encountered in post-operative period were multiple lacunar infarcts (12%), massive infarcts along the parent vessel (4%) and vasospasm (16%).

Conclusion:
Temporary clips are notorious for causing thromboembolism and strokes when applied on atheromatous vessels. One must be careful while applying it and try to use other methods like adenosine in facilitating aneurysm clipping.
Serum hepcidin levels and cardiovascular outcomes in patients on maintenance hemodialysis
Authors: Anupama Kankokaran Vadakkeveetil , Yadla Manjusha 
Published: September 2022

Background
Cardiovascular mortality is high in patients on maintenance hemodialysis. Different factors and plausible mechanisms have been explained for the increased risk. A recent concept of iron dysregulation and the related biomarker serum hepcidin was thought to be one of the novel markers of cardiovascular disease. We undertook this study to study the fatal and nonfatal cardiovascular events in dialysis population.

Patients and methods
All the patients who satisfied inclusion criteria were included in the study. All the patients have been on either twice-/thrice-weekly dialysis with polysulfone membrane of 1.3-m2 surface area. Serum hepcidin levels were estimated in blood samples using the appropriate techniques. All the patients were followed up for 18 months to assess the fatal and nonfatal cardiovascular outcomes.

Results
A total of 80 patients satisfied the criteria and were followed up. Mean serum hepcidin levels were 116.3 ± 32 ng/ml. On univariate analysis of factors influencing mortality, age, sex, and presence of comorbidities did not show significant association, but the levels of serum bicarbonate, albumin, creatinine, cholesterol, triglycerides, and the high-sensitivity C-reactive protein, hepcidin, showed a significant association with mortality. Serum hepcidin level of 120 ng/ml predicted mortality with a sensitivity of 100% and specificity of 85%.

Conclusions
Serum hepcidin is associated with all-cause mortality and cardiovascular mortality in patients on hemodialysis. Hepcidin levels may serve a good predictor of cardiovascular outcomes in patients on hemodialysis.

Published: September 2022

Background
Diabetic nephropathy is the major complication of diabetes and is one of the leading causes of end-stage renal disease. Early identification of nephropathy is crucial to slow down this process. Assessment of albuminuria is used as an early clinical marker for impaired kidney function. The aim of this study is to evaluate the magnitude of microalbuminuria (MA) in children with type 1 diabetes and determine the factors correlated to it.

Patients and methods
A cohort study that was carried out on diabetic children attained the endocrinology clinic in our hospital from August 2019 to October 2020. Children aged 6–18 years old with a history of 2 years of diabetes were subjected to history, examination, and investigation, including urea, creatinine, lipid profile, hemoglobin A1c, and 24-h urinary albumin were done twice.

Statistical analysis used

χ
2, Fisher exact, and independent Wilcoxon t test for comparison between groups. Spearman and Pearson's for correlations.

Results
The median (interquartile range) of MA in the first visit was 10 mg/24 h (6.15–20 mg/24 h) in the first visit versus 9.5 mg/24 h (4.9–23.55 mg/24 h) in the second visit, with an insignificant P value. The abnormal numbers of hemoglobin A1c in the first visit were 85.7 and 79.3% in the second visit; P value is 0.350. Children with abnormal MA were 13.2% in the first visit versus 20% in the second visit with only four patients having persistent MA. MA was positively correlated to the Tanner stage in the first visit to blood pressure, serum triglyceride, and Tanner stage in the second visit, and negatively correlated to high-density lipoprotein.

Conclusion
Most of our patients had uncontrolled diabetes with an increasing prevalence of MA over time.

Authors: Aderibigbe Gbenga Jacob , Agi Chukwuemeka , Robinson Ebbi D 
Published: September 2022

Background:
Chronic liver disease is characterized by progressive hepatic fibrosis and changes in hepatic vascular hemodynamics. Sonography is a readily available tool in the assessment of the hepatic hemodynamic alterations that occur in chronic liver diseases.

Aim:
This study was aimed at sonographically determining the portal vein indices in apparently healthy adults by estimating the portal vein diameter, cross-sectional area, and portal vein velocity.

Methods:
This was a prospective, cross-sectional study carried out among 62 apparently healthy individuals. The participants underwent gray scale and Doppler ultrasonographic examinations of the portal vein. Data were analyzed using the Statistical Package for the Social Sciences (SPSS) IBM Corp. version 23.0 (Armonk, NY: USA). The comparison of means of two groups was with the unpaired t-test, and level of significance was set at 5% (P < 0.05).

Results:
Forty-six (74.2%) of the 62 participants recruited were male and 16 (25.8%) were female. Participants were aged 18–65 years with a mean age of 39.90 ± 10.34 years. The means of portal vein diameter, cross-sectional area, and portal vein velocity are 1.15 ± 0.12 cm, 0.88 ± 0.18 cm2, and 18.37 ± 2.04 cm/s, respectively. There was no statistically significant difference of all portal vein ultrasound parameters between males and females, except portal vein flow velocity which was higher in males, t-test = 2.273 and P = 0.027 (>0.05). There was no significant correlation between age and ultrasound parameters P > 0.05.

Conclusion:
The normal values of portal vein diameter, cross-sectional area, and portal vein velocity were established.
Evaluation of Adherence to Emergency Department Point-of-Care Ultrasound Documentation and Billing Following Intervention
Authors: Lahham Shadi , Moeller John , Kurzweil Ami , Choi Heesun , Saadat Soheil , Dang Eric , Mazumder Proma 
Published: September 2022

Background:
Over the past few years, both the scope and utility of point-of-care ultrasound (POCUS) have tremendously expanded in the clinical setting. Despite this growth, few studies have evaluated the compliance, documentation, and billing of POCUS in the emergency department (ED). The objective of this study was to evaluate the compliance of billing and documentation of POCUS and determine if a single, individualized e-mail feedback can help improve billing and documentation.

Methods:
We performed a 6-week prospective review of ED POCUSs performed. Following this review, all emergency physicians were sent an individualized e-mail regarding their ultrasound performance including the total number of ultrasounds, ultrasounds per shift, and breakdown of specific ultrasound types. Following this intervention, we collected data from an additional 6 weeks regarding ultrasound billing performance.

Results:
A total of 1532 POCUS scans were recorded for data collection. Eight hundred and five scans were enrolled in the preintervention group and 727 scans in the postintervention group. Twelve different types of POCUS scans were recorded. The preintervention group had documented 484/805 scans resulting in a 60.1% (confidence interval [CI] 56.7%–63.5%) documentation ratio. The postintervention group had documented 521/727 resulting in a 71.7% (CI 68.2%–74.9%) documentation ratio.

Conclusion:
The implementation of timely quality assurance with continuous billing reminders is essential for the maintenance and fiscal sustainability of an emergency medicine ultrasound program. Future studies should further elucidate and quantify the financial impact of modifiable factors within EDs' ultrasound documentation and billing practices.
Investigation of the Effects of Marsupialization on Histomorphological and Immunohistochemical Markers of Odontogenic Keratocysts
Authors: Barış E , Seçen I Atak , Karabulut Ş , Gültekin SE 
Published: September 2022

Background:
Despite its extensive bone resorption and high recurrence rate, marsupialization is the preferred option in the treatment of odontogenic keratocysts (OKCs).

Aim:
We aimed to assess the effect of marsupialization on histomorphological and biochemical markers of OKCs.

Materials and Methods:
The study is conducted on 48 paraffin blocks of 24 OKC cases between the years 2012 to 2018. The main clinical, radiographic, and histomorphometric measurements were recorded. Immunohistochemical staining with E-cadherin, Ki67, IL1α, TNFα, Slug, and Snail were performed and compared for pre-marsupialization and post-marsupialization values.

Results:
OKCs mostly located in the mandibular posterior region. The mean marsupialization period was 8.8 ± 6.5 (3-25) months. The mean radiographic size of OKC (57.1 ± 53.5 mm) was significantly reduced after marsupialization (22.6 ± 19.9 mm, P = 0.002). Histologically, significantly increased thickness of the OKC epithelium (p = 0.002) and collagen production (p = 0.034) was detected after marsupialization. The post-marsupialization group showed positive correlation of inflammation score to both TNFα (r: 0.69, P < 0.001) and IL-1α (r: 0.58, P = 0.008) expressions in connective tissue. Among immunohistochemical parameters, only Slug expression was significantly higher after marsupialization (p = 0.019).

Conclusion:
Our study suggests that increased Slug expression may enable the second surgery by increasing fibrosis in the cyst wall.
Analysis of One-year Postoperative Mortality and Risk Factors of Elderly Patients with Intertrochanteric Fractures after PFNA
Authors: Gu J , He S , Wang L 
Published: September 2022

Background:
Intertrochanteric fracture is very common in elderly patients, It is one of the main reasons for the elderly to be hospitalized, and is closely related to the mortality rate. With the speeding up of the population aging, the treatment of intertrochanteric fracture is becoming more and more significant. PFNA (Proximal femoral nail antirotation) is the most commonly used surgical method, although the surgical technique has improved a lot, the postoperative mortality rate after one year is still high. If we can take active and effective control measures against the high-risk factors affecting mortality in time, it will help to improve the prognosis.

Aim:
To study the 1-year postoperative mortality rate of elderly patients with intertrochanteric fractures after being treated with proximal femoral nail antirotation (PFNA) and its influencing factors.

Patients and Methods:
The data of patients with intertrochanteric fracture treated by PFNA in our hospital during the period from August 2016 to April 2020 were retrospectively studied, and the data of age, sex, type of fracture, preoperative comorbid diseases, American Society of Anesthesiology (ASA) score, the timing of the operation, duration of operation, preoperative and postoperative hemoglobin levels, albumin level, and postoperative complications were collected through medical records, and the survival rate of patients in 1 year after operation was investigated by telephone follow-up, and single-factor analysis was carried out to analyze related influencing factors.

Results:
A total of 80 patients with complete data were followed up for 1–23 months (mean 12.5 months), and totally 22 patients died within 1 year, the mortality rate was 27.5%. Single analysis results suggested that the differences in factors such as age, number of preoperative combined diseases, ASA score, preoperative and postoperative albumin levels, and postoperative complications between the survival group and the death group were statistically significant (P < 0.05).

Conclusion:
The risk factors affecting long-term death in the treatment of intertrochanteric fractures in elderly patients with PFNA shall be taken into consideration fully, and the improvement of preoperative and postoperative health status will help to reduce the postoperative mortality and improve the efficacy of surgery.

Authors: Sharma A , Bhardwaj A , Mathur RP 
Published: September 2022

Background:
Kidney transplantation in spite of being the best modality for the treatment of ESRD remains a complex therapeutic option as it has its own set of problems due to associated morbidity especially in the first month after transplantation.

Aim:
The primary aim of this study was to find the incidence, causes, and factors responsible for early hospital readmissions (EHRs) and secondary aim was to find the effect of EHR on morbidity, mortality, and graft loss.

Patients and Methods:
A retrospective analysis of the records of the chronic kidney disease (CKD) patients who underwent living donor renal transplantation. 202 patients were included in the study. Inpatient records and charts were assessed for the medical status of the patients, cause of CKD, comorbidities, admissions 3 months prior to transplant, vintage dialysis, and modality of dialysis.

Results:
Sixty-one (30.2%) patients were readmitted to the hospital once or more within 30 days of discharge after renal transplantation. Thirty-four (55.7%) patients in the EHR group were admitted once or more in the 90 days prior to transplant as compared to 48 (34%) patients in the no readmission group. Thirty-four (55.7%) patients in the EHR group were hospitalised again within 1 year of EHR and 50 (35.5%) in the no EHR group got admitted within 1 year of discharge.

Conclusions:
Renal transplant recipients with hospital admissions 90 days before transplant and readmissions within 30 days of discharge after transplantation are at high risk of morbidity and should be treated as high-risk category and should have more stringent follow-up protocols.
