Published: October 2024

Abstract
We have conducted observations of the nearby (11.46 ly) star system Procyon, using MeerKAT’s UHF (544–1087 MHz) receivers. We produce full-Stokes time and frequency integrated continuum images, as well as total intensity time series imaging at 8 s cadence, and full-Stokes vector-averaged dynamic spectra from the visibilities in order to search for transient activity such as flaring events. We detect no significant radio emission from the system, and estimate an upper limit on the circular polarization fraction of 65% (3σ confidence level). A comparison with previous Very Large Array observations places a 3σ lower limit on the spectral index between 815.5 and 8400 MHz of 0.26, however long-term significant variability over the last 33 yr cannot be ruled out without further, regular radio monitoring of the system.

Abstract
We report the recent discovery of two new eruptions of the recurrent nova M31N 2017-01e in the Andromeda galaxy. The latest eruption, M31N 2024-08c, reached R = 17.8 on 2024 August 06.85 UT, ∼2 months earlier than predicted. In addition to this recent eruption, a search of archival Palomar Transient Factory data has revealed a previously unreported eruption on 2014 June 18.46 UT that reached a peak brightness of R ∼ 17.9 approximately a day later. The addition of these two eruption timings has allowed us to update the mean recurrence time of the nova. We find 〈T
rec〉 = 924.0 ± 7.0 days (2.53 ± 0.02 yr), which is slightly shorter than our previous determination. Thus, M31N 2017-01e remains the nova with the second shortest recurrence time known, with only M31N 2008-12a being shorter. We also present a low-resolution spectrum of the likely quiescent counterpart of the nova, a ∼20.5 mag evolved B star displaying an ∼14.3 days photometric modulation.
Nursing Students' Attitudes Toward Women With Maternal Substance Use Disorders
Authors: Renbarger Kalyn M. , Anyango Jane , Pannell Anabella 
Published: October 2024

Background
Maternal substance use disorders (SUD) have challenged relationships between women with SUD and their nurses. Nurses have reported biased attitudes toward women with SUD, which can interfere with their care. However, it is not well known how nursing students perceive women with SUD and their infants. This article describes nursing students' attitudes toward women with SUD, which can be used to inform educational strategies.

Method
An inductive content analysis was used to analyze 76 reflection papers written by nursing students at a midwestern university.

Results
Three main themes were identified: (1) stigma toward women with SUD; (2) concerns for infants with neonatal abstinence syndrome; and (3) influence of clinical experiences on attitudes toward women with SUD.

Conclusion

Nursing students need more evidence-based guidance on managing their biases as well as the biases of nurses who work in maternity settings.

Les fouilles archéologiques menées dans le quartier Mériadeck et ses abords témoignent de l’occupation des sols dans une zone suburbaine et humide de la capitale de cité Burdigala. À partir du ier s. apr. J.-C., des ateliers liés notamment au travail des peaux, du cuir et de la tabletterie y sont établis. Des indices forts indiquent en outre la présence de cornetiers. Au sein de ce quartier, le site de la rue Jean-Fleuret à Bordeaux (Gironde) met en lumière les techniques de travail des peaux et la production d’objets en cuir et révèle en partie l’organisation d’un tel atelier au Haut-Empire.Dans un premier état, entre 50 et 110-120 apr. J.-C., des artisans travaillent les peaux des caprinés à l’alun et/ou à l’huile d’olive, utilisent du macro-outillage lithique et des fiches métalliques en fer sans tête et collaborent avec d’autres artisans qui produisent des objets à partir de cuirs tannés de caprinés adultes et très probablement de peaux traitées à l’alun. Puis, entre 110-120 et 130-140 apr. J.-C., la spécialité de l’atelier change et les bovinés adultes sont préférés aux caprinés pour le travail des peaux. Il s’agit de la première attestation, durant l’Antiquité, d’emploi de l’alun pour le « passage en blanc » de peaux de bovinés, procédé de hongroyage que l’on pensait apparu à l’époque moderne. L’utilisation d’alun s’amplifie sur le site durant cette période, tandis que l’huile de Bétique n’est plus sollicitée.Au sein du même atelier, tabletiers et cornetiers s’associent aux artisans des peaux traitant les bovinés. Des objets en peau continuent à être assemblés, sans que l’on puisse déterminer si des cuirs tannés de bovinés sont exploités par les artisans de l’atelier.L’activité identifiée rue Jean-Fleuret cesse aux environs de 150-160 apr. J.-C., période à partir de laquelle l’espace semble mis en culture, peut-être jusqu’à la fin du iie s. Un site voisin localisé à 100 m à l’est du premier, l’îlot Fly, semble prendre le relais en termes d’activité artisanale, comme l’indiquent les batteries de cuves en bois réparties dans deux espaces desservis par un débarcadère en bois. Au iiie s., les installations y sont à leur tour abandonnées. Un dépotoir établi sur les berges du cours d’eau reflète une activité proche pratiquée par des cornetiers. L’association d’amphores de Lipari et d’amphores à huile africaines suggèrent que les artisans traitant les peaux devaient maintenir leur activité à proximité.

Authors: Kistan Jesne , Wing Jeffrey , Tshabalala Khanyisile , Van Hougenhouck-Tulleken Wesley , Basu Debashis 
Published: October 2024

Background: Screening for traditional risk factors of cardiovascular disease is well known in primary healthcare (PHC) settings. However, other risk factors through newer tools (such as bioelectrical impedance analysis [BIA]) could also be predictors of increased cardiovascular risk (CVR). Body composition estimates (body fat percentage, body water percentage, body lean mass) by BIA and its association to CVR have been studied with variable results.Aim: This study assesses the body composition estimates and their association with CVR in the South African PHC setting.Methods: A retrospective record analysis was conducted on a cohort of de-identified patients utilising the ABBY® Health Check Machine at a PHC facility in South Africa between May 2020 and August 2022. The ABBY Machine estimates body fat percentage (BF%) and body water percentage (BW%) estimates from BIA. Cardiovascular risk based on the Framingham-risk-score was stratified into high, medium and low CVR. An analysis of variance was used to determine mean differences of BF% and BW% among these groups.Results: A total of 4008 records (n = 4008) were used in the final analysis. The majority of patients were female (70.1%) with a mean age of 33.6 years. Higher mean BF% (35.75% vs. 31.10% vs. 27.73%; p 0.0001) and lower mean BW% (49.46% vs. 53.15% vs. 56.18%; p = 0000) were found to be significantly associated with high CVR.Lessons Learnt: This study demonstrated the use of newer technologies that could assist in the identification of CVR in low resource PHC settings.
Survey on the radiology report at Chris Hani Baragwanath Academic Hospital: Clinician and radiologist perspectives
Authors: Thormahlen Liane , Wessels Robyn M. , Viljoen Ilana M. 
Published: October 2024

Background: The radiology report is the primary means of conveying imaging findings between radiologists and clinicians. As a result, clinician satisfaction with the radiology report is an indicator of its quality and clinical relevance. It is crucial to identify factors that can enhance the radiology report in order to improve service delivery.Objectives: This study evaluates clinician and radiologist opinions, preferences and clinician utilisation of the radiology report.Method: Mixed quantitative and qualitative survey questionnaires were distributed in-person and online from December 2022 to February 2023 to a total of 287 clinicians and 43 independent medical practitioners specialising in radiology.Results: A total of 73.0% of radiologists and 56.5% of clinicians expressed satisfaction with the radiology reports. Additionally, 72.0% of radiologists expressed dissatisfaction with the history provided on the referral forms. It was found that 87.6% of clinicians read the radiology report, while 26.2% reviewed the radiological imaging without referring to it. Interestingly, 77.8% of clinicians preferred itemised listed reports, whereas 53.8% of radiologists preferred reports in paragraph format. It was discovered that 69.6% of radiologists and 65.4% of clinicians preferred a standardised reporting format.Conclusion: More than half of the clinicians and most of the radiologists expressed satisfaction with the radiology report. Both clinicians and radiologists showed a preference for a structured reporting format. A crucial element in constructing a good radiology report was having a relevant clinical history. The radiologist continued to be the preferred professional for interpreting radiological imaging.Contribution: This survey was a good starting point for improving communication between clinicians and radiologists. This will ultimately result in reports that are more useful to clinicians and radiologists who have a better understanding of what should be included in reports and how they should be structured.

Authors: Chalak Anita , Pawade Yogesh , Maksane Shalini 
Published: October 2024

Background and Aim:
Competency-based medical education curriculum introduces several innovative reforms like foundation course (FC) in Phase-I MBBS. However, the implementation process of FC has not been evaluated systematically, which necessitates the development and validation of an evaluation tool for FC. This study was aimed to develop and validate a reliable and valid tool for evaluating the implementation process of the FC, in order to enhance its effectiveness.

Materials and Methods:
This descriptive mixed-method study recruited 33 participants meeting the inclusion criteria. The evaluation tool was developed and shared with six experts participated in Delphi rounds. Multiple Delphi rounds were conducted, the responses were collected, and qualitative feedback from the experts was analyzed. The tool was revised based on the feedback and shared with 16 participants, including the six experts, for evaluating the relevance and usefulness of each item. The content validity ratio (CVR) and content validity index (CVI) of the items were calculated and items were further revised based on these scores. The revised tool was piloted on 17 participants for estimating its reliability.

Results:
The content validity of the tool was established by statistically high item-CVI (>79%) and scale-CVI (0.946). The CVR values of the items (0.5–1.0) indicated their essentiality. The acceptable reliability of the tool was confirmed by a Cronbach’s α of 0.73.

Conclusion:
The tool for evaluating the implementation process of FC met the criteria of validity and reliability and can be applied to FC for any medical college in India.
Investigating the role of various extracellular matrix in androgenetic alopecia: Insights from immunostaining and quantitative analysis – A pilot study
Authors: Lai I-Tzu , Chang Yi-Han , Chu Chia-Bao , Chung Pei-Lun , Hsu Chao-Kai , Yang Chao-Chun 
Published: October 2024

Abstract
Androgenetic alopecia (AGA) is the most common hair loss, characterized by miniaturization of hair follicles, shortened anagen, and prolonged telogen phases. Clinically, distinct patterns of hair loss distribution are evident between males and females. The pathogenesis of AGA is considered a mutual interplay of genetic, hormonal, and environmental factors. Mechanical properties of the scalp, for example, skin stiffness, have also been proposed as an important factor. To date, no comprehensive study has been conducted to demonstrate the density and distribution of various extracellular matrix (ECM) components at different dermal depths in AGA. To address this knowledge gap, we conducted immunohistochemical staining in patients with pattern hair loss to analyze the distribution of ECM components. Our findings reveal distinct distribution patterns of collagen I, collagen III, and elastin fibers within different dermal layers in male and female AGA cases. Notably, the intensity of elastin staining was significantly increased in all dermal layers in the male AGA skin, compared to the normal scalp skin. In summary, our study highlights the significance of ECM components in both male and female AGA.

Published: October 2024

BACKGROUND:
One common and blinding consequence of diabetes is diabetic retinopathy. However, adherence to regular screening remains a challenge for Saudi adults. The goal of this study is to investigate and identify the barriers that hinder Saudi diabetic adults from adhering to screening for diabetic retinopathy.

MATERIALS AND METHODS:
This cross-sectional study was conducted in a sample of adult diabetic patients throughout Saudi Arabia. Data was collected using a self-administered validated questionnaire comprising following five primary sections: sociodemographic information, profile of diabetes, knowledge of diabetic retinopathy, behaviors, and hurdles to diabetic retinopathy screening. Sample selected using snowball sampling technique. Questionnaire was converted into Google Forms and was shared with study participants via E-mail and several social media sites, including Facebook and WhatsApp during November and December 2023. Data analyzed using SPSS; mean and standard deviation were calculated for continuous variables, whereas categorical data was presented as frequency and percentage. Logistic regression analysis determined barriers for adherence to screening for diabetic retinopathy.

RESULTS:
The mean age of the study group was 61.6 ± 15 years, and 58.3% were female. Out of 393 respondents, 71% had undergone retinopathy screening in the past few months; 29.0% had a history of diabetic retinopathy. Participants who knew about retinopathy were eight times more likely to have eye screening compared to those who did not know about retinopathy (odds ratio = 8.05, P < 0.001). Less screening chance was observed among those who had acquired their knowledge from the Internet (odds ratio = 0.23, P = 0.002) or relatives (odds ratio = 0.21, P = 0.002) compared to those who had been advised by their physicians.

CONCLUSION:
These findings underscored the multifaceted nature of barriers to regular screenings within the Saudi Arabian healthcare system. By understanding and addressing these barriers, healthcare systems can enhance the effectiveness of screening programs and improve health outcomes.

Authors: Saeed Abdullah A. , Al Khaldi Yahia M. , Falqi Tariq A.I. , Qarnan Mohammed A. , Alharthi Zaid S. , Alshafea Abdullah A. 
Published: October 2024

BACKGROUND:
Efficient allocation of healthcare resources is essential for meeting the increasing demand for healthcare services. This study aimed at exploring the performance of both one- and two-shift Primary Healthcare Centers (PHCCs) and examining the efficiency of healthcare centers to discover how efficiency is affected by the levels of resource allocation and staffing.

MATERIALS AND METHODS:
The study was conducted at 31 PHCCs assigned to cover extended hours, from 4:00 PM to 8:00 AM during May-October 2023. Study employed a quantitative approach and the data envelopment analysis technique to assess the efficiency of PHCCs, specifically focusing on night shift performance. Data were collected through interviews and surveys with primary healthcare staff including 99 doctors, 119 nurses, and 139 support staff using structured questionnaire. The DEA technique was utilized to measure the relative efficiency of the PHCCs by comparing the inputs and outputs.

RESULTS:
Out of 31 PHCCs, 45.2% run two shifts. Over the reported period, a total of 126,619 patient visits were recorded; 81.7% came to the two-shift PHCCs and 18.3% to the one-shift PHCCs. On average, each two-shift PHCC received approximately 161 visits/ shift, and the one-shift received 123 visits. Upper respiratory tract infections accounted for 30% of morbidities and chronic diseases for more than 20%. The performance of the two-shifts PHCCs revealed varying levels of efficiency with a score of 1.00 for the most efficient PHCC and 0.31 for the least efficient PHCC.

CONCLUSION:
This study underscores the importance of data-driven decision-making for healthcare administrators. Ongoing assessments and benchmarking are essential for continuously improving the quality of healthcare service and optimizing utilization of resources. Future research in this field can further explore the factors that contribute to healthcare efficiency and provide deeper insights into healthcare resource management and optimization of service delivery.
Knowledge of self-management and asthma control among asthma patients attending a polyclinic in Western part of Singapore
Authors: Khor Joanne H. , Szücs Anna , Goh Lay Hoon 
Published: October 2024

BACKGROUND:
Self-management is important for asthma control, yet it is unclear whether asthmatic patients have sufficient knowledge to optimally manage their disease. We examined the associations between the knowledge of self-management in adult patients attending a polyclinic in Singapore, sociodemographic factors, and asthma control.

MATERIALS AND METHODS:
A cross-sectional survey was conducted among adult asthmatic patients in a public primary care clinic (polyclinic) using convenience sampling. A a structured and validated self-administered questionnaire solicited the responses of study participants. Questionnaire comprised three sections: (1) Sociodemographic and asthma-related variables, (2) Modified Asthma Self-Management Questionnaire (ASMQ), and (3) The GINA assessment of asthma control. Participants completed the questionnaire in the clinic waiting area and returned them into a sealed box in the same area. Data were analyzed using SPSS version 29.0. Summary statistics were used to describe the study sample; t-test or analysis of variance (ANOVA), as appropriate, tested the differences in self-management knowledge by sociodemographic characteristics. Logistic regression was used to determine the association between asthma control and self-management knowledge controlling for sociodemographic characteristics.

RESULTS:
The sample comprised 141 asthma patients; Out of a total of 100 points, the mean ASMQ score was 46.8 (standard deviation 21.7). The scores for the knowledge of self-management of Asthma differed by age, level of education, and having been taught about asthma on bivariate analyses (P < 0.05). Linear regression showed a significant association of asthma self-management knowledge with educational level only. No association was observed between ASMQ scores and asthma control.

CONCLUSION:
There were gaps in patients’ knowledge about asthma self-management, although they were generally knowledgeable about the inhaler technique. Higher education levels were associated with higher levels of knowledge beyond the effect of age and having been instructed about asthma, suggest that it is crucial that educational programs on asthma are made accessible to patients with lower levels of education. Further research needs to determine whether asthma educational programs targeting the knowledge gaps found in this study can improve knowledge of self-management and asthma control.

Published: October 2024

Abstract

Savrana Shukla is one of the Krishnagata Rogas (corneal pathologies) mentioned in Ayurvedic texts. The Lakshanas of Savrana Shukla can be correlated with the clinical features of superficial punctate keratitis. Superficial punctate corneal keratitis is characterized by multiple, spotty lesions in the outermost layer of the cornea. A 30-year-old male approached the Shalakya Tantra outpatient department with complaints of foreign body sensation, mild pricking pain, redness, and watering of the left eye for 4 days. On history taking and slit lamp examination, it was revealed that the patient had superficial punctate keratitis due to trichiasis. Seka (pouring medicine on the closed eyes) and Vidalaka (application of medicated paste on the outer part of the eyes) were given as treatment for 5 days and epilation was done considering the cause (trichiasis). The subject had significant improvement for both subjective and objective parameters. The clinical features in this subject correspond to Prathama Patala Savrana Shukla Lakshanas (epithelium and Bowman’s membrane involvement) and are Sadhya (curable) according to Acharya Vagbhata. This case report highlights the efficacy of Kriyakalpa treatments in managing Savrana Shukla.
