Abstract
We analyze the cool gas in and around 14 nearby galaxies (at z < 0.1) mapped with the Sloan Digital Sky Survey IV MaNGA survey by measuring absorption lines produced by gas in spectra of background quasars/active galactic nuclei at impact parameters of 0–25 effective radii from the galactic centers. Using Hubble Space Telescope/Cosmic Origins Spectrograph, we detect absorption at the galactic redshift and measure or constrain column densities of neutral (H i, N i, O i, and Ar i), low-ionization (Si ii, S ii, C ii, N ii, and Fe ii), and high-ionization (Si iii, Fe iii, N v, and O vi) species for 11 galaxies. We derive the ionization parameter and ionization-corrected metallicity using cloudy photoionization models. The H i column density ranges from ∼1013 to ∼1020 cm−2 and decreases with impact parameter for r ≳ R

e
. Galaxies with higher stellar mass have weaker H i absorption. Comparing absorption velocities with MaNGA radial velocity maps of ionized gas line emissions in galactic disks, we find that the neutral gas seen in absorption corotates with the disk out to ∼10 R

e
. Sight lines with lower elevation angles show lower metallicities, consistent with the metallicity gradient in the disk derived from MaNGA maps. Higher-elevation angle sight lines show higher ionization, lower H i column density, supersolar metallicity, and velocities consistent with the direction of galactic outflow. Our data offer the first detailed comparisons of circumgalactic medium (CGM) properties (kinematics and metallicity) with extrapolations of detailed galaxy maps from integral field spectroscopy; similar studies for larger samples are needed to more fully understand how galaxies interact with their CGM.
A Rotating Satellite Plane around Milky Way–like Galaxy from the TNG50 Simulation

Published: August 2023

Abstract
We study the satellite plane problem of the Milky Way (MW) by using the recently published simulation data of TNG50-1. Here, we only consider the satellite plane consisting of the brightest 14 MW satellites (11 classical satellites plus Canes Venatici I, Crater II, and Antlia II). One halo (haloID = 395, at z = 0, hereafter halo395) of 231 MW-like candidates possesses a satellite plane as spatially thin and kinematically coherent as the observed one has been found. Halo395 resembles the MW in a number of intriguing ways: it hosts a spiral central galaxy, and its satellite plane is almost (∼87°) perpendicular to the central stellar disk. In addition, halo395 is embedded in a sheet plane, with a void on the top and bottom, similar to the local environment of MW. More interestingly, we found that 11 of the 14 of the satellites on the plane of halo395 arise precisely from the peculiar geometry of its large-scale environment (e.g., sheet and voids). The remaining three members appeared at the right place with the right velocity by chance at z = 0. Our results support previous studies wherein the satellite plane problem is not seen as a serious challenge to the ΛCDM model and its formation is ascribed to the peculiarities of our environment.
The Missing Link: Testing Galactic Chemical Evolution Models with the First Multi-isotopic Abundances in Solar Twin Stars

Published: August 2023

Abstract
We present the first isotopic abundances of both 13CO and C18O in solar twin stars and test the results against several galactic chemical evolution (GCE) models with different nucleosynthesis prescriptions. First, we compare M-band spectra from IRTF/iSHELL to synthetic spectra generated from custom solar atmosphere models using the PHOENIX atmosphere code. Next, we compare our calculated abundances to GCE models that consider isotopic yields from massive stars, asymptotic giant branch stars, and fast-rotating stars. The 12C/13C ratios determined for this sample of solar twins are consistent with predictions from the selected GCE models; however, the 16O/18O ratios tentatively contradict these predictions. This project constitutes the first in a stellar chemical abundance series seeking to (1) support the James Webb Space Telescope as it characterizes exoplanet atmospheres, interiors, and biosignatures by providing host star abundances; (2) identify how unexplored stellar abundances reveal the process of galactic chemical evolution and correlate with star formation, interior, age, metallicity, and activity; and (3) provide improved stellar ages using stellar abundance measurements. By measuring elemental and isotopic abundances in a variety of stars, we not only supply refined host star parameters, but also provide the necessary foundations for complementary exoplanet characterization studies—and ultimately contribute to the exploration of galactic, stellar, and planetary origins and evolution.

Published: August 2023

Introduction: Acute upper respiratory tract infections (AURTIs) are associated with a significant burden on society attributed to medical care and loss of productivity. Novel therapies that are able to shorten disease duration, while providing symptom relief and being well tolerated, are an unmet medical need.
Aim: The main objective of this trial was to investigate the efficacy and safety of Aviron Rapid, a dietary supplement containing andrographolide, proprietary spirulina, and humic acid, in the management of AURTIs in adolescents and children.
Materials and methods: This randomized, double-blind, placebo-controlled trial was conducted between January 2020 and March 2020 in 85 general practitioner practices in Bulgaria. Adolescents (13–17 years) and children (5–12 years) with a clinical diagnosis of AURTI were randomly assigned to receive standard symptomatic therapy + Aviron Rapid or placebo for 5 and 7 days, respectively. The primary endpoints of this trial were the number (and percentage) of clinically recovered patients and the mean disease duration.
Results: In total, 380 adolescents and 401 children were enrolled in 2 age cohorts and randomly assigned to treatment with Aviron Rapid or placebo. The percentage of patients meeting the criteria for clinical recovery was significantly higher in the Aviron Rapid group compared with the placebo group from 24 and 48 hours after initiation of treatment in adolescents and children, respectively. Aviron Rapid treatment significantly reduced the duration of disease, of fever, and of antipyretics intake in both adolescents and children. When compared to placebo, a significantly higher percentage of adolescents and children on Aviron Rapid achieved a persistent decrease in temperature of less than 37°C as soon as 24 hours after starting treatment. Overall, a low number of adverse events was reported and no major differences in the incidence of individual adverse events were observed between the two treatment groups in both cohorts.
Conclusions: This clinical trial demonstrated the efficacy of Aviron Rapid in the management of acute upper respiratory tract infections in adolescents and children. Aviron Rapid treatment rapidly increased the number of clinically recovered patients and reduced overall disease duration and duration of symptoms, in particular fever, while being well tolerated.

Published: August 2023

Introduction: Exercise-induced desaturation is common in patients with moderate to severe chronic obstructive pulmonary disease (COPD). It provides additional information about physical capacity and disease evolution, and it is an important predictor of mortality.
Aim: To compare the six-minute walk test (6MWT) and the cardio-pulmonary exercise test (CPET) as methods for detection of desaturation in COPD patients. To explore the relationship between exercise-related desaturation, symptom questionnaires (mMRC, CAT, and SGRQ), pulmonary function testing (PFT), and blood-gas analysis.
Patients and methods: Forty adult male COPD patients, mean age 67.2±8.4 years (mean ± SD) underwent 6MWT, CPET, PFT, blood-gas analysis, and scored their symptoms (mMRC, CAT, and SGRQ). Oxygen desaturation was monitored during exercise. Desaturation was defined as a decrease in SpO2 of ≥4% and values ≤88% held for ≥3 minutes.
Results: The studied patients had COPD stage 2A – 4D (GOLD 2011). The patients were categorized into two groups – with desaturation (A, n=19) and without desaturation (B, n=21). CPET elicited 21 individuals who experienced desaturation, 19 of them desaturated during 6MWT as well. In the whole group, the percentage of desaturation during CPET was 6.6±4.9% compared to 6.0±4.9% during 6MWT (p&lt;0.001). There was a significant difference in the maximal oxygen consumption reached by the patients in group A – 16.2±4.5 and group B – 19.9±4.7 (p=0.016). Desaturation during 6MWT correlated significantly with that during CPET (r=0.75, p&lt;0.001).
Conclusions: Exercise-related desaturation in patients with moderate to severe COPD could easily and reliably be detected by 6MWT.

Authors: Karamanliev Martin , Yotsov Tsanko , Dimitrov Dobromir 
Published: August 2023

Introduction: Totally implantable access ports (TIAPs) are commonly used in oncologic patients undergoing ongoing chemotherapy. The methods of choice for implantation are the subclavian vein puncture approach and the cephalic vein cutdown technique, followed by internal jugular vein access and external jugular vein access.
Materials and methods: We analyzed all patients who had a central venous access implanted by a single surgeon at the University Hospital in Pleven between October 2018 and January 2022, with the aim of determining the success rate and safety of the cephalic cutdown technique for placing totally implantable access ports.
Results: 135 totally implantable access ports were inserted in the study period. Median age of patients was 69.2 years (range, 35-86 years). There were 71 (52.59%) women and 64 (47.41%) men. In 7 patients, the tip of the catheter was reported to go at the distal part of the subclavian vein and axillary vein on the ipsilateral side after initial placement and was repositioned under real-time fluoroscopic guidance. Successful placement of a totally implantable access port using the cephalic cutdown technique was reported in 127 patients (94.07%). No postoperative pneumothorax, hemothorax, or vessel injury were reported. One case of surgical site infection was seen on postoperative day (POD) 7. Late postoperative complications occurred in 3 patients with catheter-related bacteremia all after POD 30 (81, 95, and 172 days after the procedure). One patient died.
Conclusions: Totally implantable access ports placed using the cephalic vein cutdown technique can be used safely and with high success rates in oncological patients.
Barriers and Enablers to Nurses' Engagement With Continuing Professional Development: A Survey
Authors: Pracilio Amy , Cashin Andrew , Wilson Nathan J. 
Published: August 2023

Background:
Continuing professional development (CPD) is perceived as a pivotal component of building and maintaining nursing skill and capacity. Exploring motivators for CPD engagement can aid program adaptation and improvement. The goal of this study was to survey the barriers, enablers, and changes of Australian RNs' engagement with CPD in general during the coronavirus disease 2019 (COVID-19) pandemic. An additional goal was to understand factors influencing the interest of participants to engage with programs focused on care for people with intellectual disability and/or autism.

Method:
This study was a cross-sectional exploratory survey.

Results:
Most of the sample had engaged with CPD in the previous 12 months, and the most reported topics were related to COVID-19. Sixty percent of nurses saw a change in volume of CPD. Younger nurses, with fewer years of experience, and practicing in major cities, were significantly more likely to report less CPD.

Conclusion:

It is pivotal that the design and promotion of CPD curricula consider the motivators and barriers for nurses' engagement with them.

Authors: Ranjan Ravi , Khare Rahul , Guguloth Naresh , Jaiswal Sankalp , Pandey Sarvesh Kumar , Shukla Ajay , Yadav Ajay Kumar , Singh Devender 
Published: August 2023

Abstract

Background:
Fragility fractures, which most typically afflict postmenopausal women’s wrists, hips, and spines, are frequently caused by osteoporosis. In comparison to other times and places, the incidence is approximately two times higher during perimenopause. The risk of future wrist fractures is markedly increased by a prior fracture. Many studies have emphasized the importance of screening as a preventative measure against future fractures in these people with osteoporosis. This study aimed to assess the utility of distal forearm dual-energy X-ray absorptiometry (DEXA) as a screening tool to assess the risk of development of primary osteoporotic fractures at the distal end radius (DER) in postmenopausal women.

Objectives:
The study’s objective was to determine whether DEXA at the distal end of the radius could be used as a screening technique to determine the fragility fractures.

Materials and Methods:
The method followed included a cross-sectional study conducted on 60 patients (30 in group A: postmenopausal women with DER fracture, and 30 in group B: postmenopausal women without fractures), who fulfilled the inclusion criteria.

Results:
All patients underwent DEXA scan at three sites (hip, spine, and distal radius). On comparison of T-score between Hip, Spine, DER in group A , T-score with value <−2.5 was 53.33% at Hip, 70% at Spine and 70 % at DER with Total of 64.44%. mean±S.D at Hip was −2.73±1.27, at Spine was −3.23±1.25 and at DER was −3.42±162. P-value 57 was 0.298, Hip vs Spine: 0.184 , Hip vs DER : 0.184, Spine vs DER : 1. On comparison of Tscore between Hip, Spine, DER in group B, T-score with value <−2.5 was 30% at Hip, 56.67% at Spine, 13.33% at DER with total of 33.33%. mean±SD was −2.09±0.9 at Hip, −2.54±1.32 at Spine and −1.64±0.78 at DER. P-value was 0.002,Hip vs Spine : 0.037, Hip vs DER: 0.209, spine vs DER: 0.0009. this supports above study and we can use DER DEXA Scan as a screening tool in postmenopausal women. There was a significant deterioration of T-score at DER and hip and spine in the fracture group compared with the control group (P < 0.001).

Conclusion:
Some postmenopausal women showed preferential bone loss at the distal region of the radius, which would make them more susceptible to fragility fractures there. In general, forearm DXA for the evaluation of local bone density may prove beneficial to screening people at risk for distal radial fractures and makes it easier to identify patients who need osteoporosis treatment early on.

Authors: Khan Mohammad Jesan , Asif Naiyer , Sankhwar Dilip Kumar , Aggarwal Pankaj 
Published: August 2023

Abstract
Periprosthetic fractures over the total knee arthroplasty (TKA) are increasing in aged population. When open reduction is considered as a treatment option there is excessive soft tissue insult causing reduction of periosteal blood supply resulting in delayed union and weight bearing. Patient of the case of postosteoarthritis TKA with periprosthetic supracondylar fracture treated with retrograde intramedullary nailing. The patient after 12 months of follow-up gained a comparable range of motion with early weight bearing and union. Retrograde intramedullary nail, through compatible TKA component, is a feasible option and has numerous advantages over other conventional methods being less invasive, less time-consuming, less blood loss, preservation of fracture hematoma, and periosteal blood supply.
Audiological findings and non-audiological correlates in individuals with acoustic neuroma: A systematic review
Authors: Jayagopi Chinnarasu , Neelamegarajan Devi 
Published: August 2023

Abstract
Many individuals with vestibular schwannoma experience hearing loss along with tinnitus and dizziness. The accurate diagnosis of acoustic neuromas requires audiological evaluation, radiological evaluations, and other brain imaging findings. This review study aimed to compile the articles comprising audiological and non-audiological evaluations of computed tomography (CT) and magnetic resonance imaging (MRI) and their correlations in individuals with acoustic neuroma. From the 38 finalized full-length articles, 13 studies were included in the systematic review. The results of these articles reported that most patients with acoustic neuroma have significant unilateral hearing loss, mostly descending or sloping type. Along with the hearing loss, these individuals showed marked abnormality in auditory brainstem response peaks and reduced speech discrimination scores. Approximately 4%–6% of the acoustic neuroma patients did not show any symptoms of hearing loss. The audiological test results did not significantly correlate with the tumor size or the site. However, small tumors or tumors at the early stage were difficult to diagnose through audiological tests alone. Non-audiological evaluations such as CT and MRI have increased the diagnosis of acoustic neuroma at the early stage. The incidence of vestibular schwannoma has increased globally during the past 30 years. This study insists on the utility of non-audiological evaluation in diagnosing acoustic neuroma, even though the patient shows no audiological symptoms such as hearing loss and tinnitus. Also, it recommends the audiologist consider the radiological findings while determining the diagnosis in patients indicating unilateral hearing loss, sudden sensorineural hearing loss, tinnitus, reduced speech understanding, and dizziness.

Published: August 2023

Abstract

Purpose:
The coexistence of problem behaviors and speech-language communication issues is widely known. But there is ambiguity in the management of children who have both behavioral and language difficulties on whether or when to make a referral for behavioral intervention. Hence, the present study aimed to develop a screening checklist to detect problem behaviors among children with communication disorders.

Materials and Methods:
A preliminary screening checklist was made after reviewing seven tests that are commonly used to assess problem behaviors. After content validation by three expert professionals and incorporating the observations made by them, a 13-item-screening checklist was finalized. The checklist was administered on 100 Malayalam-speaking parents of children with communication disorders aged below 14 years, identified using a systematic random sampling technique from the clinical service database (2019–2021) of All India Institute of Speech and Hearing. The interview was carried out over a telephone call.

Results:
The results showed that the 13-item-screening checklist was sufficient to assess problem behaviors in children in communication disorders. The results also showed a significant difference in problem behavior severity and frequency scores across communication disorders. Of the different communication disorders, the autism spectrum disorder group showed the highest presence of problem behavior.

Conclusion:
The easy and quick 13-item problem behavior-screening checklist, validated by expert professionals, is sufficient to assess problem behaviors in various communication disorders. The data show higher prevalence of and significant differences in problem behaviors across communication disorders, with autism spectrum disorder group showing the highest scores on problem behavior.
Comparison of Enamel Surface Roughness between Light-cured and Self-cured Composites used in Orthodontic Bonding by using Atomic Force Microscopy
Authors: Mandolil George S. , Louis Chraseeta , Rai E. Ajay , Shetty Praveena 
Published: August 2023

Introduction:
Debonding is a procedure of removing orthodontic attachments along with the entire residual adhesives from the surface of enamel following orthodontic treatment completion. The objective of the orthodontists should be to restore the surface of enamel as closely as possible to natural enamel without inducing iatrogenic injury and with minimal loss of enamel structure. Bonding of brackets on enamel involves surface etching, application of primer, and adhesive. All these steps involve the risk of damaging the enamel surface and changing its original morphology. Upon completion of orthodontic treatment, the debonding procedure followed by residual resin removal further damages the enamel, producing scratches, cracks, grooves, removal of fluoride-rich external enamel layer, and increasing the enamel roughness. The rough enamel surface inhibits proper cleaning and thus invites plaque deposition, bacterial retention, stain formation, and thus dampening the aesthetic appearance of the teeth. Restoring the enamel to its original morphology is a challenge. A variety of mechanical methods have been proposed to achieve satisfactory resin removal with least possible enamel damage following bracket debonding. The Enhance finishing and Pogo polishing system (Dentsply, Milford, USA) is also widely used and is made up of polymerized urethane dimethacrylate resin, aluminium oxide, silicon dioxide, and fine diamond powder.

Methods:
The sample of 50 tooth extracted for orthodontic purpose was procured as per the inclusion criteria. Buccal surfaces of teeth on the area where bracket is bonded and then debonding is done. After residual resin removal with Enhance system finishing and polishing bur. Measurements for each specimen were measured and mean was calculated and evaluated with the help of Atomic Force Microscopy (Baseline roughness data).

Result:
Self cure composite gives relatively lesser surface roughness when compared to light cure composites.

Conclusion:
The study shows that the self cure adhesive gives the smoother enamel surface when compared to the tooth treated with light cure adhesive after debonding and finishing and polishing.
