Abstract
Chemical anomalies in planet-hosting stars (PHSs) are studied in order to assess how the planetary nature and multiplicity affect the atmospheric chemical abundances of their host stars. We employ APOGEE DR17 to select thin-disk stars of the Milky Way, and crossmatch them with the Kepler Input Catalog to identify confirmed PHSs, which results in 227 PHSs with available chemical abundance ratios for six refractory elements. We also examine an ensemble of stars without planet signals, which are equivalent to the selected PHSs in terms of evolutionary stage and stellar parameters, to correct for Galactic chemical evolution effects, and derive the abundance gradient of refractory elements over the condensation temperature for the PHSs. Using the Galactic chemical evolution corrected abundances, we find that our PHSs do not show a significant difference in abundance slope from the stars without planets. However, when we examine the trends of the refractory elements of PHSs, based on the total number of their planets and their planet types, we find that the PHSs with giant planets are more depleted in refractory elements than those with rocky planets. Among the PHSs with rocky planets, the refractory depletion trends are potentially correlated with the terrestrial planets’ radii and multiplicity. In the cases of PHSs with giant planets, sub-Jovian PHSs demonstrate more depleted refractory trends than stars hosting Jovian-mass planets, raising questions on different planetary formation processes for Neptune-like and Jupiter-like planets.

Abstract
Jets and disk winds arise from materials with excess angular momentum ejected from the accretion disks in forming stars. How these structures are launched and how they impact the gas within the innermost regions of these objects remains poorly understood. MWC349A is a massive star that has a circumstellar disk that rotates in accord with Kepler’s Law, with an ionized wind and a high-velocity jet launched from the disk surface. The strongly maser-amplified emission of hydrogen radio recombination lines (RRLs) observed toward this system provides a comprehensive picture of its ionized environment with exquisite detail. In this Letter, we present Atacama Large Millimeter/submillimeter Array observations of the H26α RRL and continuum emission obtained with the highest angular resolution ever used toward this source (beam of ∼0.″02). The maser RRL emission is resolved for the first time and clearly delineates the ionized disk, wind, and jet. We analyzed the RRL data cubes with the 3D non-LTE radiative transfer model MORELI, confirming that the jet is poorly collimated. We found that the jet orientation is closer to the rotation axis of the system than derived from spatially unresolved data. This study confirms that hydrogen RRL masers are powerful probes of the physical structure and kinematics of the innermost ionized material around massive stars.
Spectral Variance in a Stochastic Gravitational-wave Background from a Binary Population
Authors: Lamb William G. , Taylor Stephen R. 
Published: August 2024

Abstract
A population of compact object binaries emitting gravitational waves that are not individually resolvable will form a stochastic gravitational-wave signal. While the expected spectrum over population realizations is well known from Phinney, its higher-order moments have not been fully studied before or computed in the case of arbitrary binary evolution. We calculate analytic scaling relationships as a function of gravitational-wave frequency for the statistical variance, skewness, and kurtosis of a stochastic gravitational-wave signal over population realizations due to finite source effects. If the time derivative of the binary orbital frequency can be expressed as a power law in frequency, we find that these moment quantities also take the form of power-law relationships. We also develop a numerical population synthesis framework against which we compare our analytic results, finding excellent agreement. These new scaling relationships provide physical context to understanding spectral fluctuations in a gravitational-wave background signal and may provide additional information that can aid in explaining the origin of the nanohertz-frequency signal observed by pulsar timing array campaigns.

Abstract
Multiwavelength polarimetry and radio observations of Swift J1727.8–1613 at the beginning of its recent 2023 outburst suggested the presence of a bright compact jet aligned in the north–south direction, which could not be confirmed without high-angular-resolution images. Using the Very Long Baseline Array and the Long Baseline Array, we imaged Swift J1727.8–1613 during the hard/hard-intermediate state, revealing a bright core and a large, two-sided, asymmetrical, resolved jet. The jet extends in the north–south direction, at a position angle of −0.60° ± 0.07° east of north. At 8.4 GHz, the entire resolved jet structure is

These images reveal the most resolved continuous X-ray binary jet, and possibly the most physically extended continuous X-ray binary jet ever observed. Based on the brightness ratio of the approaching and receding jets, we put a lower limit on the intrinsic jet speed of β ≥ 0.27 and an upper limit on the jet inclination of i ≤ 74°. In our first observation we also detected a rapidly fading discrete jet knot 66.89 ± 0.04 mas south of the core, with a proper motion of 0.66 ± 0.05 mas hr−1, which we interpret as the result of a downstream internal shock or a jet–interstellar medium interaction, as opposed to a transient relativistic jet launched at the beginning of the outburst.
Adaptation of Clinical Practice Guideline for Assessment of Liver Fibrosis in Patients with Non Alcoholic Fatty Liver Disease in Isfahan Province

Published: August 2024

Abstract
Non-alcoholic fatty liver disease (NAFLD) refers to the presence of hepatic steatosis (accumulation of fat in the liver to over 5% of its weight) in the absence of secondary causes of fat accumulation in the liver such as excessive alcohol use. NAFLD is divided into two types: non-alcoholic fatty liver (NAFL) and non-alcoholic steatohepatitis (NASH). Therefore, in this clinical guideline, we sought to determine general and important policies for this disease and modify its managment approaches. We adapted this guideline for the management of NAFLD in Isfahan Province. This guideline was developed by clinical appraisal and review of the evidence, available clinical guidelines, and in consultation with members of the Isfahan Chamber of the Iranian Association of Gastroenterology and Hepatology. Biopsy is recommended as the most reliable method (gold standard) to diagnose steatohepatitis and fibrosis in patients with NAFLD. NAFLD fibrosis score (NFS) and fibrosis-4 (FIB-4) are recommended as the test with the highest predictive value for advanced fibrosis in patients with NAFLD compared to other serologic tests. Among the noninvasive methods used to assess liver fibrosis, transient elastography (TE) is preferable to other methods.

Published: August 2024

AbstractTo adapt to the changing conditions and respond to the needs of society, health systems need continuous changes and reforms in their structure and performance, and subsequently, they need to evaluate their indicators. Therefore, this study aimed to investigate the impact of the health system transformation plan (HTP) on the functional indicators and efficiency of hospitals in a country in the Middle East region (Iran). A systematic literature review was conducted according to the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines using the online databases Medline, EMBASE, Scopus, Pubmed, SID, Magiran, and Medlib from 2013 to 2022 using a combination of medical subject heading terms (‘health system transformation plan [Mesh] OR ‘health reform [Mesh] OR implementation of the health transformation plan [Mesh] ‘’AND (‘performance indicators’ [Mesh]) ‘’AND (‘Iran’ [Mesh]). STATA version 11 were used for data analysis. A total of 20 reports (cross-sectional, cohort, and case-control) were identified for this study. The results showed that after the HTP, the indices of bed occupancy rate and bed turnover rate have increased and the index of bed turnover distance has decreased. On the other hand, after the implementation of this plan in hospitals, the average of patients’ length of stay has increased. The implementation of HTP has improved most of the performance indicators of hospitals and has generally led to an increase in the productivity of hospitals compared to that before the implementation of the plan. However, efforts to strengthen weak performance indicators and identify effective indicators along with adopting correct policies to increase the overall efficiency of hospitals can be effective in improving HTP.
Ideal Time to Practice Yoga: Insights from Traditional Yoga Texts and Observations from Scientific Studies: A Narrative Review
Authors: Iyer Swathi , Bhargav Hemant , Bhat Raghavendra 
Published: August 2024

Background:
Those interested in practicing yoga often lack clarity on what would be the best time to practice yoga. This paper intends to review the ancient, scientific and contemporary literature to understand this. Ancient texts on yoga mention that the best time to practice yoga is early morning hours. Lack of information and standardization regarding timing of the yoga practice is a key indicator for us to explore current study on the influence of time on yoga practice which can set a direction for the future studies and possible outcomes that can be derived by choosing the best time to practice yoga.

Methods:
In this review article we searched the scientific and traditional literature to find an answer to this question. We searched Google Scholar and PubMed using the following criteria: 1) Research studies examining the influence of timing on practice of Yoga, exercise, meditation or mindfulness on various variables 2) Studies published in English language until March 1, 2024.

Results:
We found sixteen studies; most of them were surveys that tried to assess the influence of time of physical activity/mindfulness on various health parameters. We observed that there are studies that suggest that the best time to practice yoga could depend on the specific outcome that is attempted to be achieved. Awareness of the appropriate time to practice yoga is important for several reasons, including enhancing the effectiveness of the practice, to regulating the body's internal clock, reducing the chances of distractions and developing a consistent regimen for practice.

Conclusion:
Engaging in morning vigorous exercise or yoga is better than evening vigorous yoga or exercise for enhancing the state of mind/mood of the practitioner and improving sleep quality in the night. Evening yoga should be less intense, relaxing and more meditative. Intense exercise / yoga in the evening may reduce the sleep quality in night. Studies also suggest that the difference in chronotype of the individual could possibly play a role in determining the best time to practice yoga.

Abstract

Background:
Sparse data is available comparing the outcome of Community-acquired acute kidney Injury (CA-AKI) and Hospital-acquired acute kidney injury (HA-AKI).

Aims:
This study was undertaken to compare the demographic, clinical spectrum and in-hospital outcomes of CA-AKI versus HA-AKI.

Patients and Methods:
A prospective cohort study was conducted from October 2020 to December 2021 in the inpatient departments (IPDs) of a tertiary-care referral centre in north India. A total of 65 patients with CA-AKI and 32 patients with HA-AKI were enrolled. The characteristics and outcomes of AKI in both groups were compared.

Results:
The mean age of patients in the CA-AKI and HA-AKI groups was 46.7 years and 45.5 years respectively. The CA-AKI group had significantly higher baseline serum creatinine, serum creatinine at admission, proportion of patients requiring renal replacement therapy, proportion of patients having oligo-anuria and hyperkalemia at presentation. Despite more patients in the CA-AKI group being in AKI-Stage 3 at presentation, in-hospital mortality was observed to be lower in this group. However, on comparing the overall survival, both groups were found to be comparable. The independent predictors of mortality were the presence of lung disease and the requirement of vasopressor support at presentation.

Conclusion:
It was observed that both recovery and dialysis dependency were more common in patients with CA-AKI. Both groups had comparable overall survival. Only two factors, i.e. the presence of lung disease and the requirement of vasopressor support at presentation predicted the survival of AKI patients. The type of AKI was not an independent predictor of mortality in such patients.

Published: August 2024

Abstract

Background:
Chronic rhinosinusitis is the most common otolaryngologic disease that has a great impact on patient’s quality of life. Patients refractory to medical therapy require functional endoscopic sinus surgery (FESS).

Aim:
To evaluate and compare the disease specific quality of life in patients of chronic rhinosinusitis pre operatively and after FESS using the Sino Nasal Outcome Test 22 (SNOT 22).

Patients and Methods:
This prospective longitudinal study was conducted on 30 patients with chronic rhinosinusitis. History, clinical, diagnostic sinonasal endoscopy and radiological findings were recorded. For assessing the quality of life, the SNOT-22 questionnaire was used preoperatively and after 1 week, 1 month and 3 months after undergoing FESS.

Results:
About 43.3% of the patients were males and 56.7% were females. Seventy percentage were between 18 and 30 years. Nasal obstruction was the most common presenting symptom (96.6%), followed by nasal discharge (80%). Diagnostic sinonasal endoscopy and non-contrast computed tomography scan of paranasal sinuses reflected the extent of the disease. The mean pre-operative SNOT-22 score was 40.4 ± 12.06 and a decrease in mean post-operatives scores was observed during their post-operative visits at 1 week (11.77 ± 3.39), 1 month (4.67 ± 2.77) and 3 months (2.47 ± 1.28) which were statistically significant.

Conclusion:
Chronic rhinosinusitis patient’s refractory to medical treatment showed statistically significant improvement in their quality of life after undergoing FESS.

Background: Weightlifting is one of the sports that contribute to Olympic medals for Indonesia. With the demand to contribute medals at the Olympics, a thorough screening is needed to evaluate athletes for possible risks of injury. Moreover, the lifting movements involve the joints, muscles, and skeleton. Therefore, the sport poses a very high risk of injury, especially to the shoulders. Knowing the athlete's Range of Motion (ROM) is important to see a good range of motion. This study aimed to observe ROM differences between injured and non-injured weightlifters. Method: An observational study was conducted on 16 athletes (10 male and 6 female) with the following characteristics for male (24.1 ± 6.7 years, 168.2 ± 2.5 cm, 83.0 ± 11.9 kg, 29.2 ± 4.0 kg/m2) and female (18.8 ± 1.6 years, 158.6 ± 3.8 cm, 65.2 ± 7.9 kg, 27.2 ± 4.5 kg/m2) participants. In data analysis, all athletes went through the screening stage. After that, the body composition and ROM of both arms were measured using InBody 270 and Humantrak 3D Human Movement Analysis, with statistical significance determined at a value <0.05 using the Mann-Whitney test in Minitab. Result: The study found a significant difference in the range of motion of the shoulder between athletes who had injuries and those who did not have injuries. Conclusion: This research revealed a decreased range of motion in weightlifting athletes with injuries.

Wolf Tones and Humidity in Violins
Authors: Yoshimura Hiro , Love Henry 
Published: August 2024

This paper attempts to, perhaps for the first time in this type of studies, quantitatively evaluate the severeness (as defined in this paper) of the undesired wolf tones on a violin as the surrounding humidity changes. The severity of the wolf tones was evaluated by a skilled violinist under various humidity conditions. It was found that a total duration and frequency of occurrence of wolf tones during a set period time are largest around 50% humidity, a humidity at which violins are recommended to be maintained for optimizing the projection across the entire register of the instrument, whereas other characteristics of the wolf tones, such as modulation index and the period, did not exhibit significant changes over the humidity change. When the humidity deviates from 50%, the total durations and the occurrence frequency of the wolf tones both diminishes. On the other hand, the amplitude (i.e. volume) of the wolf tones are larger on the lower humidity and the higher humidity ends, and was smallest around 50% humidity. These findings may shed new light on the traditional theories and analysis of wolf tones as well as on evaluations of various wolf tones elimination methodologies. It was also found that although the evaluation method involved some subjectivity, this way of evaluating the wolf tones had consistency and a good degree of reliability, paving a new way to quantify the wolf tones.
The Impact of Remittances on Food Inflation in Bangladesh: An ARDL Approach
Authors: Rahman Ashiqur , Afroza Akter Sumi  , Sadekin Md Nazmus 
Published: August 2024

Purpose of the study: This study aims to investigate how Bangladesh's food inflation is affected by remittance influx. Methodology: The analysis utilizes secondary data collected from 2005 to 2022. In order to accomplish the goals, this study employs the food inflation rate as an endogenous variable, while workers' remittance, official exchange rate, and broad money supply are used as exogenous factors. The data is sourced from the World Development Index (WDI). In this investigation, co-integration is assessed using the Autoregressive Distributed Lag (ARDL) model to provide an accurate outcome. Findings: The study's findings show that, both in the short and long term, the influx of remittances from migrants has a positive and considerable impact on driving up food inflation. This analysis shows that while having a negative short-term impact, the money supply and exchange rate have a long-term, positive, and considerable influence on food inflation. Application of the Study: This research proposes that promoting agricultural output and motivating recipients of remittances to invest in income-generating activities can effectively reduce their reliance on food consumption. If these recommendations are effectively followed, the inflow of workers' remittances will have a positive impact on the economy and contribute to reducing inflationary challenges. Originality of the study: By employing the most recent data set and cutting-edge methodology, the present research adds to the body of available research by demonstrating a link between food inflation and remittances.
