Abstract
We present the the new Swift/UVOT+MaNGA (SwiM) catalog (SwiM_v4.1). SwiM_v4.1 is designed to study star formation and dust attenuation within nearby galaxies given the unique overlap of Swift/UVOT near-ultraviolet (NUV) imaging and MaNGA integral field optical spectroscopy. SwiM_v4.1 comprises 559 objects, ∼4 times more than the original SwiM catalog (SwiM_v3.1), spans the redshift range z ≈ 0.0002–0.1482, and provides a more diverse and rich sample. Approximately 5% of the final MaNGA sample is included in SwiM_v4.1, and 42% of the SwiM_v4.1 galaxies are cross-listed with other well-known catalogs. We present the same data as SwiM_v3.1, including UVOT images, Sloan Digital Sky Survey (SDSS) images, and MaNGA emission-line and spectral index maps with the same pixel size and angular resolution for each galaxy, and a file containing galaxy and observational properties. We designed SwiM_v4.1 to be unbiased, which resulted in some objects having low signal-to-noise ratios in their MaNGA or Swift data. We addressed this by providing a new file containing the fraction of science-ready pixels in each MaNGA emission-line map, and the integrated flux and inverse variance for all three NUV filters. The uniform angular resolution and sampling in SwiM_v4.1 will help answer a number of scientific questions, including constraining quenching and attenuation in the local Universe and studying the effects of black hole feedback. The galaxy maps, catalog files, and their associated data models are publicly released on the SDSS website (a description of the SwiM VAC is provided at https://www.sdss4.org/dr17/data_access/value-added-catalogs/?vac_id=swift-manga-value-added-catalog, and the data are stored on the SDSS Science Archive Server at https://data.sdss.org/sas/dr17/manga/swim/v4.1/).
Fast Radio Bursts: Electromagnetic Counterparts to Extreme Mass-ratio Inspirals
Authors: Li Rui-Nan , Zhao Zhen-Yin , Gao Zhifu , Wang Fa-Yin 
Published: October 2023

Abstract
Recent observations discovered that some repeating fast radio bursts (FRBs) show a large value and complex variations of Faraday rotation measures (RMs). The binary systems containing a supermassive black hole and a neutron star can be used to explain such RM variations. Meanwhile, such systems produce low-frequency gravitational-wave (GW) signals, which are one of the primary interests of three proposed space-based GW detectors: the Laser Interferometer Space Antenna (LISA), Tianqin, and Taiji. These signals are known as extreme mass-ratio inspirals (EMRIs). Therefore, FRBs can serve as candidates of electromagnetic counterparts for EMRI signals. In this Letter, we study the EMRI signals in this binary system, which can be detected up to z ∼ 0.04 by LISA and Tianqin for the most optimistic case. Assuming the cosmic comb model for FRB production, the total event rate can be as high as ∼1 Gpc−3 yr−1. EMRI signals associated with FRBs can be used to reveal the progenitor of FRBs. It is also a new type of standard siren, which can be used as an independent cosmological probe.
Instrumental Effects of Lyα Properties in CLASSY and Implication for HETDEX and JWST
Authors: Martinez Zorayda , Gazagnes Simon , Berg Danielle A. 
Published: October 2023

Abstract
In this work, we quantify the effects of spectral resolution (R) on the measured Lyα properties and determine the robustness of Lyα trends measured with different spectrographs. We select 9 galaxies with diverse Lyα properties from the COS Legacy Archive Spectroscopic SurveY and measure the equivalent width and peak velocities of their Lyα profiles from their high-resolution spectra (R ∼ 4225–15000). We downgrade these spectra to several lower resolutions (R ∼ 800–3500) and re-measure the Lyα properties. Using these values, we derive the systematic errors and investigate the robustness of Lyα properties as a function of spectral resolution. We find that equivalent width can be robustly measured at low R. However, the minimal spectral resolution required to obtain robust measurements of the Lyα peak velocities is R ≳ 2600 (Δv = 115 km s−1).

Published: October 2023

Abstract
We present the discovery of a new stellar companion to GJ 835, detected using the Differential Speckle Survey Instrument on the 4.3 m Lowell Discovery Telescope and the Astrophysical Research Consortium 3.5 m telescope at Apache Point Observatory. This new companion joins a known companion in the system, making the system triple. Using 2MASS and Gaia data, as well as our observed properties, we estimate projected separations and spectral types for the three components in the system.
Nova traditio. La fête de la Conception de la Vierge Marie au Mont Saint-Michel (XIIe-XVe siècles)
Authors: Dary Marie-Bénédicte 
Published: October 2023

L’expression nova traditio employée par
Bernard de Clairvaux dans sa biographie de saint Malachie (§ 42) pour
louer son œuvre de restaurateur et d’innovateur convient pour désigner
le statut de la solennité de la Conception de la Vierge quand elle est
introduite début XIIe siècle au Mont Saint-Michel
au sein d’une tradition liturgique partiellement héritée de Guillaume
de Volpiano. En complément des études liturgiques réalisées à
l’occasion du Millénaire monastique du Mont Saint-Michel, l’auteur
montre la dépendance de l’ajout de la messe du 8 décembre au
Sacramentaire du Mont [Rouen, Bibl. patrim. François Villon,
ms Suppl. 116] avec le Missel de Winchester [Le Havre, Bibl. mun.,
ms 330 (A32)], propriété de la bibliothèque de saint Wandrille,
manuscrit qui a vraisemblablement été le pont entre Angleterre et
Normandie dans l’introduction de la fête du 8 décembre. On observe
durant les siècles suivants à l’abbaye montoise une fidélité à cette
solennité par son inscription dans les calendriers, par le choix d’un
rit propre à la fête pour la messe et l’office et par le degré de la
fête. Cependant la mise en ordre du XIIIe siècle
dont le poids s’exerce aussi dans le domaine liturgique modifie,
certes de façon réduite, la portée théologique de la fête. Ce double
mouvement, fondé sur la stabilité et la création d’une tradition
propre à l’abbaye mais qui reste perméable aux influences extérieures,
ne fait pas du scriptorium du Mont Saint-Michel un artefact mais un
paradigme du développement de la « Fête aux Normands ». La comparaison
avec les traditions des scriptoriums de Fécamp et Jumièges permet de
l’affirmer et de mieux cerner les enjeux de cette « innovation
traditionnée » pour l’abbaye montoise. Mais elle laisse également
entrevoir l’existence d’une réforme liturgique active au XIIIe siècle à laquelle les scriptoriums du Mont et de
Fécamp se sont soumis.
The decolonising of theology through African proverbs
Authors: Resane Kelebogile T. 
Published: October 2023

The decolonisation of theology has been a subject in academia for almost 60 years. In this article, although referring to African proverbs as a way of decolonising theology all the proverbs are in the Setswana language, which the author is knowledgeable of and is conversant with; however, most of these proverbs cut across tribal, ethnic, and geographical boundaries. The objectives are, among others, to demonstrate the richness of African philosophy and wisdom expressed through proverbs, idioms, and folklore. These proverbs are sapient and capable of articulating theology, therefore making theology contextual and relevant for Africans. Definitions of proverbs start the discussions. A literature review and common knowledge are used to validate the facts stated. Three areas are chosen where and how the proverbs can be used to formulate and validate theological truth. Firstly, the area of ethics where proverbs are used in ethical instructions regarding morality and values, community and cooperation, leadership, family life, as well as respect and integrity. The second area is theologising through proverbs by which dogmatisation can be achieved highlighting the view of theology, a database in theologising, an authority base, and hermeneutical principle. Thirdly, proverbs can be used to strengthen communion ecclesiology. The conclusion is drawn that theology can unshackle itself from the clutches of colonialism, if African philosophy and wisdom expressed through proverbs can be engaged in hermeneutical processes and the contextualisation of theology in the African context.Contribution: The article engages the Setswana language, African philosophy, and theology to strengthen the theme of decolonising theology. It is both interdisciplinary and intradisciplinary as it engages anthropology, linguistics, human philosophy, theological ethics, dogmatics, and ecclesiology.

Published: October 2023

Background
Gallbladder diseases (GBDs) are one of the most common surgical diseases. Gallbladder stones (GBSs) are the commonest pathology affecting the gallbladder. Gallbladder cancers (GBCs) are rare though lethal malignancy. GBCs represent a diagnostic and clinical challenge, since its presentation is often nonspecific and its diagnosis commonly occurs at an advanced stage.

Aim
The aim of this study is to evaluate the outcome of the routine histopathological examination of all cholecystectomy specimens.

Patients and methods
This study was a retrospective analysis, conducted on 1011 patients who underwent cholecystectomy for symptomatic cholecystitis, in KASR AL-AINY Hospital, General Surgery Department between June 2021 and November 2022.

Results
Age of patients ranged from 14 to 79 years, females patients were 857 and male patients were 154. Chronic cholecystitis was the most common GBD, 1006 specimens were benign. One specimen was premalignant; dysplasia, and 4 specimens were malignant; 1 case was focal intraepithelial neoplasia, and 3 cases were adenocarcinomas. There was no statistically significant difference between both sexes. The mean thickness of gallbladder was 0.39 cm. multiple gallbladder stones were found in 619 patients, single stones were found in 249 patients, and no stones were found in 143 patients. The largest stone size was 6.00 cm. Female patients have increased preponderance for the development of all GBDs. Nonneoplastic lesions were more common below fifth decade and neoplastic lesions thereafter.

Conclusion
In this study, the rate of incidental GBCs is very low. All cholecystectomy specimens were routinely sent for histopathology to detect incidental GBC.
Evaluation of a noninvasive uroflowmetry parameter (Delta Q value) in detrusor underactivity and bladder outlet obstruction
Authors: Mostafa Diaa , Higazy Ahmed , Ali Mohamed H. , Elsayaad Mohamed F. , Abuelnaga Mohamed 
Published: October 2023

Purpose
To determine the significance of the Delta Q value in discrimination between detrusor underactivity (DU) and bladder outlet obstruction (BOO) in adult male patients.

Methods
A total of 238 patients in this cohort study underwent pressure-flow study. Patients were divided into two groups based on UDS outcomes: DU (n = 121) and BOO (n = 117). From uroflowmetry, 5 variables including maximal flow rate (Qmax), average flow rate (Qave), voiding volume (VV), postvoid residual urine (PVR), and the difference between (Qmax) and (Qave) known as (Delta Q) were obtained. Diagnostic prediction of these variables was evaluated with DU and BOO.

Results
Delta Q was less in the DU group compared with the BOO group 2.9 ml/s and 6.2 ml/s, respectively. Delta Q showed a promising diagnostic value in the discrimination between DU and BOO. A cut-off value of 6.1 ml/s was found to be discriminatory between the two groups with a sensitivity of 96.58% and specificity of 92.79%.

Conclusion
Delta Q value has proven to be a useful noninvasive screening and diagnostic tool in differentiating between DU and BOO in men with obstructive lower urinary tract symptoms.
Evaluation of the diagnostic accuracy of preoperative ultrasound for axillary lymph nodes in breast cancer patients
Authors: Ali Mahmoud , Abusahmen Suzan S. , Khallaf Emad , Attia Mohamed 
Published: October 2023

Background
Breast cancer is the most prevalent cancer and the second leading cause of death among women is breast cancer. The likelihood of survival rises with early breast cancer diagnosis, which lowers death rates. For the treatment of breast cancer, axillary lymph nodes (ALNs) must be correctly staged and managed. The main goals of ALNs staging are to gather prognostic data and information that might influence management decisions.

Objective
To evaluate the accuracy of the preoperative ultrasound in detection of malignant ALNs in breast cancer patients.

Methods
The records of breast cancer patients at the breast surgery unit of Kasr Alainy Hospital, between 2017 and 2020, were reviewed. Patients with an axillary ultrasound report who underwent a sentinel lymph node biopsy (SLNB) or axillary lymph node dissection (ALND) were enrolled in the present study. Demographic and clinicopathologic characteristics including age, family history, body mass index (BMI), primary tumor size, histological and biological grade, Lymphovascular invasion (LVI), extracapsular invasion (ECE), were evaluated.

Results
Out of the 348 Breast Cancer patients who were managed in our department, the age range was 28–89 years (median age 52 years). The histopathology results of the tumor were 96% with invasive duct carcinoma (IDC) 2.3% invasive lobular carcinoma (ILC) and 1.7% were mixed ductal/lobular. Cortical thickness greater than 3 mm had a significant difference for positive nodal status, effacement of hilum had a sensitivity 56.2% in detecting positive lymph nodes (LNs), round LNs shape had a sensitivity of 82.3% in detecting true positive LNs. Pathological LNs by ultrasound had a sensitivity of 93% and specificity of 77% in detecting true positive LNS, BMI was not significant in ultrasound detection of pathological LNs.

Conclusion
The data shows that axillary ultrasound by its assessment has revealed to be useful in detection of malignant LNs with a sensitivity of 93.1% and specificity 77% in detecting true malignant LNs.
Assessment of the lipodermal flap for avoidance of lateral dog-ear deformity in mastectomy
Authors: Asal Mohamed F. , Elfayoumy Tarek A. , Sabry Sara , Abdullatif Ahmed 
Published: October 2023

BackgroundPatients who are at an elevated risk of developing lateral dog ears deformity following mastectomy, such as those who have high body mass index, or who have too much tissue in the lateral chest wall, and who are not ideal candidates for immediate reconstruction or the Goldilocks mastectomy, should have a lateral dog-ear assessment and should consider the lipodermal flap technique. The purpose of this study was to explain a modification to the mastectomy incision known as the lipodermal flap procedure that avoids this deformity and improve patient satisfaction and quality of life.MethodsThis study included 50 female breast cancer patients who were recommended for a modified radical mastectomy (MRM); they had large cup-size breasts and were expected to develop a dog-ear deformity after the mastectomy.ResultsThe type of mastectomy was MRM in 48 patients, and palliative toilet mastectomy in only two patients. The operative time median is about 1.5 h (1.5–1.5), the wound length median is about 20 cm (19–20), and the blood loss median is about 200cc (180–220). Scar discomfort: 45 patients (90%) did not experience scar discomfort, and five patients (10%) felt scar discomfort. Regarding wound dehiscence, 46 patients had no wound dehiscence and four patients (8%) had wound dehiscence and 48 patients (96%) had no flap necrosis and 2 patients (4%) had flap necrosis. Cosmetic result: 4 patients (8%) with wound cosmesis were not accepted and 46 (92%) patients were accepted; 46 (92%) patients were satisfied; 100% of the cases had no dog ear in the lateral part of the mastectomy scar.ConclusionsThe lipodermal flap technique is safe, feasible, and reliable and could be applied during MRM once lateral dog-ear deformity is anticipated with a high satisfaction rate and lower incidence of wound complication.
One stage repair of giant inguinal herniae: a feasible option
Authors: Musa-Olomu Abdus-Samiu A. , Musa Titilayo M. , Adeleke Nurudeen A. , Abdulraheem Nurudeen T. , Ajape Abdulwahab A. 
Published: October 2023

Background
Surgical repair of giant inguino-scrotal hernia (GIH), based mainly on anatomical considerations and minimal organ resection; without the use of mesh or pneumo-peritoneum.

Patients/method
Over a-15-year period (2005-2019), all patients managed for GIH were reviewed. They had an elevation of the scrotum, and foot of the bed, to allow for the reducible part of the hernia to gradually return and expand the abdominal cavity. Volume estimations of the hernias were done applying Archimedes’ principle followed by a-5-day bowel preparations. Abdomino-inguinal/Inguinal incisions (depending on the size), were made to repair the hernias taking advantage of the special anatomical make-up of the abdominal cavity.

Results
A total of 20 male patients with GIH were treated; 13 were on the right while seven were left-sided. All the GIHs were repaired successfully without any serious morbidity; one patient had a scrotal hematoma that was managed conservatively and another developed a ventral hernia (5 cm long), which was repaired at a later day. An average of 6 months follow-up revealed no recurrence or any other complications.

Conclusion
Surgical techniques in the repair of GIH are many and varied but its rarity has made the adoption of any specific technique(s) impossible. A fairly large series like ours over many years might be a fruitful attempt at solving this problem.
A prospective comparative study among Alvarado score, appendicitis inflammatory response (AIR) score, and adult appendicitis score (AAS) in the diagnosis of acute appendicitis in adults
Authors: Abouelnour Moataz T. , Elmahdy Tamer M. , Abdallah Hamdy S. , Elkhadrawy Osama H. 
Published: October 2023

Background
Acute appendicitis (AA) is the most common condition presenting with acute abdomen requiring emergency surgery. Several clinical scores were developed to diagnose AA.

Aim
This study aimed to compare the diagnostic accuracy of three clinical scores (Alvarado score, appendicitis inflammatory response (AIR) score, and adult appendicitis score (AAS)) in the diagnosis of AA.

Methods
This prospective study was conducted on 100 adult patients (aged ≥ 18 years) presenting with acute abdomen suspicious of noncomplicated AA. Patients with complicated AA (abscess, mass, or diffuse peritonitis) and patients with uncomplicated AA subjected to nonoperative management (NOM) were excluded from our study. The histopathological results were used as the gold standard for diagnosis of AA to which the three clinical scores results were compared.

Results
Our study included 100 patients (60 males and 40 females), all of whom, had histopathologically proven AA. Due to this outcome, we could only conclude and compare the sensitivities of the three scores. Alvarado score had the highest overall sensitivity (91% at cut-off value > 4 points), followed by AAS (80% at cut-off value > 10 points), then AIR score (71% at cut-off value > 4 points) however, the difference between Alvarado score and AAS was not statistically significant. In males, the Alvarado score had the highest sensitivity (88.3%), followed by AAS (86.7%), then the AIR score (71.7%) at the same cut-off values however, the difference between the Alvarado score and AAS was also not statistically significant. In females, Alvarado score had the highest sensitivity (95%) followed by AAS and AIR scores (70% for both) with a statistically significant difference. Obesity did not influence the outcome of the three scores.

Conclusions
Alvarado score and AAS are more sensitive than the AIR score. In relation to sex, Alvarado’s score is the most sensitive in females.
Acute surgical abdomen during the COVID-19 pandemic: a retrospective study on clinical and therapeutic challenges
Authors: Erfan Moatasem A. , Alwardany Ibrahim N. 
Published: October 2023

Background
As with other medical specialties throughout the epidemic, general surgical clinics’ treatment protocols have changed because of the COVID-19 pandemic, which has become a serious danger to healthcare systems. The presence of severe COVID-19 in young individuals and among medical workers has exacerbated the psychological burden on clinicians treating patients suspected of having or being infected with SARS-CoV-2, even if comorbidities and older age are statistically linked to higher death rates.

Patients and methods
A retrospective comparative study included patients who were admitted to the emergency room (ER), surgical, or managing conservatory for acute surgical abdomen. All subjects were divided into three groups. 1186 patients; out of them, 490 cases were examined before the pandemic, 334 cases were examined during the pandemic, and 362 cases were examined after vaccination.

Results
Before the pandemic, the commonest cause of acute abdomen was appendicitis (21.8%), strangulated hernia (21%), and cholecystectomy (17.8%). During the pandemic, the commonest cause of acute abdomen was appendicitis (21.8%), cholecystectomy (16.8%), and Mesenteric venous occlusion (MVO)/Mesenteric Artial occlusion (MAO) (13.8%). After the pandemic, the commonest causes of acute abdomen were cholecystectomy (25.4%), appendicitis (24.6%), and exploration abdomen (11.9%). The time of management differed significantly among the studied groups. The highest requirement for immediate intervention was attributed to the before pandemic group, while during the pandemic group was associated with conservative management, and after conservative management.

Conclusion
The Sars-Cov-2 pandemic highly affected the clinical presentation, aetiology, diagnostic and paraclinical investigations, and therapeutic management, as well as the changes in emergency practice procedures.
