Abstract
We report the discovery of intertwined/entangled substructures toward the bubble wall of NGC 3324 below a physical scale of 4500 au, which is the sharp edge/ionization front/elongated structure traced at the interface between the H ii region and the molecular cloud. The sharp edge appears wavy in the Spitzer 3.6–8.0 μm images (resolution ∼2″). Star formation signatures have mostly been traced on one side of the ionization front, which lies on the molecular cloud’s boundary. The James Webb Space Telescope’s (JWST) near- and mid-infrared images (resolution ∼0.″07—0.″7) are employed to resolve the sharp edge, which has a curvature facing the exciting O-type stars. The elongated structures are associated with the 3.3 μm polycyclic aromatic hydrocarbon (PAH) emission, the 4.05 μm ionized emission, and the 4.693 μm H2 emission. However, the PAH-emitting structures are depicted between the other two. The H2 emission reveals numerous intertwined substructures that are not prominently traced in the 3.3 μm PAH emission. The separation between two substructures in the H2 emission is ∼1.″1 or 2420 au. The intertwined substructures are traced in the spatial areas associated with the neutral to H2 transition zone, suggesting the origin of these structures by “thin-shell” instability. Furthermore, an arc-like feature traced in the Spitzer 3.6–8.0 μm images is investigated as a bipolar H ii region (extent ∼0.35 pc) at T

d
∼25–28 K using the JWST images. A massive-star candidate VPHAS-OB1 #03518 seems to be responsible for the bipolar H ii region.
Updated Reference Wavelengths for Si vii and Mg vii Lines in the 272–281 Å Range
Authors: Young Peter R. 
Published: November 2023

Abstract
New reference wavelengths for atomic transitions of Mg vii and Si vii in the 272–281 Å wavelength range are derived using measurements from the Extreme-ultraviolet Imaging Spectrometer (EIS) on board the Hinode spacecraft. Mg vii and Si vii are important ions for measuring plasma properties in the solar transition region at around 0.6 MK. The six Si vii wavelengths are 13–21 mÅ and 7–11 mÅ longer than the values in the NIST Atomic Spectra Database (ASD) and the compilations of B. Edlén, respectively. The four Mg vii wavelengths are shorter than the values in the ASD by 8–12 mÅ but show reasonable agreement with the Edlén values. The new wavelengths will lead to more accurate Doppler shift measurements from the EIS instrument and will be valuable for spectral disambiguation modeling for the upcoming Multi-Slit Solar Explorer mission.

Abstract
We present the results of new time-series photometric observations of 29 pre–white dwarf stars of PG 1159 spectral type, carried out in the years 2014–2022. For the majority of stars, a median noise level in Fourier amplitude spectra of 0.5–1.0 mmag was achieved. This allowed the detection of pulsations in the central star of planetary nebula A72 (Abell 72), consistent with g modes excited in GW Vir stars, and variability in RX J0122.9–7521 that could be due to pulsations, binarity, or rotation. For the remaining stars from the sample that were not observed to vary, we placed upper limits for variability. After combination with literature data, our results place the fraction of pulsating PG 1159 stars within the GW Vir instability strip at 36%. An updated list of all known PG 1159 stars is provided, containing astrometric measurements from the recent Gaia DR3 data, as well as information on physical parameters, variability, and nitrogen content. Those data are used to calculate luminosities for all PG 1159 stars to place the whole sample on the theoretical Hertzsprung–Russell diagram for the first time in that way. The pulsating stars are discussed as a group, and arguments are given that the traditional separation of GW Vir pulsators in “DOV” and “PNNV” stars is misleading and should not be used.
Regard d’un anthropologue
Authors: Laurent Pierre-Joseph 
Published: November 2023

Contempler un visage peut semer le doute, conduire au trouble, à l’équivoque. Incapable de se détacher d’un visage, la fascination relève de l’ineffable. La beauté favorise un monde à deux, la fabrication d’une bulle. En cela elle est asociale, elle ne permet pas de faire société. Je formule la proposition selon laquelle pour faire société, la beauté des corps, dans le sens de son inégale répartition, a dû être régulée, prise en charge, maîtrisée. Ce texte montre comment ce fut le cas pour les sociétés coutumières étudiées par les anthropologues. Il analyse ensuite comment les sociétés contemporaines se sont émancipées des anciens principes de la régulation sociale de la beauté pour finalement valoriser une identité à fleur de peau ; enfin, il examine les conséquences de cette émancipation sur les personnes, les relations sociales et la société dans son ensemble.
Le granite albitique à colombite-tantalite et topaze des Châtelliers (Vendée) utilisé comme pierre de taille depuis le Moyen Âge : les apports de l’étude pétrologique et minéralogique
Authors: Godard Gaston 
Published: November 2023

Les matériaux de construction du donjon de Pouzauges (Vendée) sont constitués d’un granite à biotite et de cornéennes qui proviennent du massif granitique de Pouzauges, comme le démontre la richesse en baryum du feldspath alcalin du granite. Cependant, un granite blanc très particulier, riche en albite et mica blanc, renfermant des minéraux singuliers (colombite-tantalite, topaze, zinnwaldite, béryl, spessartine), a été utilisé comme pierre de taille pour les ouvertures, cheminées, coussièges et latrines. Ce granite provient des Châtelliers, situés à 9 km de Pouzauges, où de vieilles excavations sont visibles. L’observation des édifices de la région montre que ce granite fut utilisé comme pierre de taille du 12e au début du 20e siècles. Choisie pour sa faible altérabilité et ses qualités esthétiques, en particulier sa couleur ivoire, cette roche servait à la confection de pierres ouvragées pour les ouvertures, corniches et cheminées des logis et châteaux, et pour les colonnes, chapiteaux, ogives et archivoltes des églises. Pour les parements ordinaires, au contraire, on utilisait des moellons en roches locales, schistes, granite ou cornéenne. Cette étude, parmi d’autres, illustre que l’examen pétrologique des matériaux de construction peut permettre d’identifier leur provenance, en particulier lorsqu’il s’agit de roches métamorphiques ou magmatiques, à la minéralogie variée.

Recent Developments in CTE-Matched Composite Thermal Materials
Authors: Saums David L. 
Published: November 2023

A surprisingly large number of engineered materials are available to the module and system packaging engineer that have been designed for a target coefficient of thermal expansion (CTE, stated both at room temperature and across a specified range of temperatures) and possessing bulk thermal conductivity values useful for device heat dissipation. There are continuing research and development programs for new forms and variations of such materials, intended to meet continuing demands for improvement on a spectrum of requirements. These requirements include higher bulk isothermal conductivity values, lower cost, lower CTE values, reduced density and weight, and, for certain types of applications, a target CTE and highly anisotropic property. This discussion seeks to identify both existing and common materials (for comparison purposes) and new developments that are being brought to market and/or are in production today. The purpose is to add to the design engineer’s tool kit for available materials of these types. In addition, high temperature effects on selected materials are illustrated.

Published: November 2023

Abstract

Introduction
Many grafts have been described for ACL reconstruction; however, disagreements regarding globally accepted gold standard graft choice persist. Recently, the peroneus longus tendon (PLT) Autograft has been used in the field of ACL reconstruction as an alternative autograft. This study aimed to evaluate the efficacy of the peroneus longus tendon as a graft for primary ACL reconstruction and to study its possible effects on foot and ankle function.

Patients and methods
This was a prospective study that included patients who underwent ACL reconstruction using Peroneus longus tendon autograft. Results were assessed via physical examination. Donor site morbidity of the foot and ankle was assessed using Medical American Orthopedic Foot & Ankle Society (AOFAS) score and Foot and Ankle Disability Index (FADI). Postoperative knee function was evaluated by the International Knee Documentation Committee (IKDC) and Tegner-Lysholm score.

Results
Thirty patients were included in the study with a mean age of 28 years old. Peroneus longus graft diameter was 8.5 ± 0.7 mm. There was a significant difference between pre and postoperative functional scores in IKDC and Tegner-Lysholm score. Ankle scores were excellent. The mean of AOFAS was 97.7 ± 3.1 and FADI was 98.5 ± 0.5.

Conclusion
The peroneus longus tendon is an appropriate autograft source for ACL reconstruction. Its use in primary ACL reconstruction is very encouraging with minimal donor site morbidity.

Abstract

Introduction
Fracture neck of femur (FNF) represents a major public health problem worldwide. The aim of this study is to evaluate the clinical, functional outcome and rate of complications of dual mobility cup total hip arthroplasty versus bipolar hemiarthroplasty in the management of displaced fracture neck femur in elderly patients.

Methods
A prospective Randomized control study was done in a university specialized unit between January 2018 and January 2021 on 40 elderly patients had a mean age of 70.5 years (range 60-91) with displaced intracapsular FNF. 20 patients were managed by Dual Mobility Cup Total Hip Arthroplasty (DMC THA group) and 20 patients underwent Bipolar Hemiarthroplasty (BHA group) for the treatment of their femoral neck fractures with a minimum 24 months follow-up (range 24-35). Rate of dislocation postoperatively was the primary outcomes while functional outcome (Harris Hip Score), intraoperative blood loss and length of operation were the secondary outcomes.

Results
The Harris hip score (HHS) was higher in the DMC THA group and was most significant after 6 and 12 months with P value (P < 0.05). The dislocation rate was less in the DMC THA group. The BHA group demonstrated less intraoperative blood loss (P < 0.001) and a shorter length of operation (P < 0.001). However, there was no significant difference in two-year mortality with P value (P > 0.05), blood transfusion rate with P value (P = 0.471) and infection rate with P value (P = 1.000).

Conclusion
In light of our results, the use of THA DMC did not seem to increase mortality, morbidity, or complications rate like infection or bleeding but it decreases dislocation rate and increase functional outcome when compared with BHA.
Artificial intelligence (AI) and ChatGPT involvement in orthopaedic research activities, the good, the bad, and the Ugly
Authors: Hussein Sara , Khalifa Ahmed A 
Published: November 2023

Abstract
“Scientific writing is a mandatory skill for most researchers, and orthoapedic surgeons are no exception. However, improvement of the writing quality could be achieved using some assistive tools. The most recent ones involve using artificial intelligence (AI), specifically ChatGPT. Although it seems appealing for improving scientific writing and assisting non-native English speakers, its usage is still not well regulated, and ethical issues were raised regarding the misuse of these tools in the scientific research and writing process. Strict regulations controlling the involvement of these tools are still needed, and their judicious and honest utilization is mainly dependent on the researchers themselves.”

Authors: Jose Anu , Dandagi Satyajit , Chour Girish V. , Bora Sushmit P. , Dharan Minu Parvathi 
Published: November 2023

Background:
Mandibular fracture is the second most common fracture of facial bone, next to nasal bone. Twenty-five to forty percent of mandibular fractures involve the condyle. In the literature, there exists no consensus “gold standard” treatment for mandibular condylar fractures, and there is a continuing debate on whether condylar fractures should undergo closed or open reduction.

Materials and Method:
Twenty patients who had undergone open reduction and closed reduction treatment were included in the study. Clinically maximal interincisal opening, laterotrusive and protrusive movements, pain on mouth opening, malocclusion, chin deviation on mouth opening, facial nerve palsy, hematoma, infected implant, and bite force were evaluated after a minimum of 3 months postoperatively. Also, a postoperative CT is done to evaluate the anatomical position of fragment.

Results:
On evaluation of clinical parameters, both groups had comparable results. However, none of the patients in open reduction group had deviation of mandible from midline on mouth opening. Also, better anatomical repositioning is obtained in open reduction group.

Conclusion:
The results of this study suggest that the open reduction method is a better alternative to closed reduction in treatment of mandibular condylar fractures.
Comparative evaluation of regenerative potential of injectable platelet-rich fibrin and platelet-rich fibrin with demineralized freeze-dried bone allograft in the treatment of intrabony defects: A randomized controlled clinical study
Authors: Salem Saba , Dhawan Shivani , Sharma Ena , Dhawan Rajan , Mukherjee Abhilasha , Sivaraman S M 
Published: November 2023

Background:
Injectable platelet-rich fibrin (i-PRF) being in liquid form keeps graft particles clumped together forming agglutinated steak of bone graft. It has been shown to contain more platelets and long-term deliverance of growth factors in comparison with platelet-rich fibrin (PRF).

Aim:
The aim of the present study was to assess regenerative potential of i-PRF and comparing it with PRF, along with demineralized freeze-dried bone allograft (DFDBA) in the treatment of intrabony alveolar defects.

Materials and Method:
Thirty defect sites in 15 patients with bilateral intrabony defects were assigned randomly into two groups (Group I (Control group)- DFDBA + PRF and Group II (Test group)-DFDBA + i-PRF). Gingival index (GI), plaque index (PI), pocket probing depth (PPD), and relative attachment level (RAL) were recorded at baseline, 3 months, and 6 months. Linear bone growth (LBG) was recorded radiographically at baseline and 6 months.

Statistical Analysis:
ANOVA test and post hoc Tukey test were used to assess intragroup comparison of clinical parameters. Paired t-test was used to assess intragroup comparison of the radiographic parameter. Unpaired t-test was used to assess intergroup variations in all the clinical as well as radiographic parameters.

Results:
Statistically significant PPD reduction (P = 0.005) and RAL gain (P = 0.003) were found in Group II than in Group I, and no significant difference was found in other parameters. Percentage LBG was higher in Group II than Group I but the difference was not statistically significant.

Conclusion:
i-PRF with DFDBA showed more favorable results as compared to PRF with DFDBA in the management of intrabony periodontal defects.

Authors: Wadhwa Deepti , Kumar Virendra , Hasija Mukesh Kumar , Bey Afshan 
Published: November 2023

Introduction:
The purpose of this study was to determine the level of nitric oxide (NO) in both serum and saliva of smokers and nonsmokers with chronic periodontitis before and after scaling and root planing, as well as to compare the same (NO levels) with the severity of periodontitis.

Materials and Methods:
Sixty people took part in the study and were divided into three groups. The control group (Group I) involved 20 patients who were nonsmokers with healthy periodontium. The other two groups included 20 patients each, where Group II was nonsmokers with chronic periodontitis and Group III was smokers with chronic periodontitis. In addition, NO generation was quantified indirectly in this study using the Griess reaction to determine the nitrite level in serum and saliva.

Results:
The mean value of salivary and serum NO was higher in Group III than in Group II, and NO decreased considerably (P < 0.01) in both Groups II and III after treatment compared to before treatment.

Conclusion:
Serum and salivary NO levels can be used as a good predictor of the inflammatory condition of the periodontium in smokers.
A Prescription Audit in the Outpatient Department of the National Accreditation Board for Hospitals and Healthcare Providers and Joint Commission International Approved Super Speciality Hospital in the Capital Territory of India
Authors: Suman Satyam , Pravalika Jakkula , Nupur Satya , Manjula Pulluru 
Published: November 2023

Abstract

Background:
An audit is the examination and evaluation of health-care procedures and documents to compare the quality of care provided with accepted standards. The prescribing audit study is part of an audit that monitors, evaluates, and, if necessary, recommends changes in physicians’ prescribing practices. Prescription validation is a quality improvement process that aims to improve patient care.

Methodology:
A prospective observational study was conducted in the outpatient department setting of the National Accreditation Board for Hospitals and Health-care Providers and Joint Commission International approved Super Speciality Hospitals of the Capital Territory of India. Data were collected randomly, 100 prescriptions across different department settings of Super Speciality Hospitals for 1 month in November 2022. Data were analyzed on the standard format of World Health Organization core prescribing indicators and in the form of mean and percentage.

Results:
A total of 17 parameters were accessed for the prescription audit. From the data, we can predict that in a total of (n = 100) samples of prescription audit, only 21.65% (368) cases had noncompliance, 67.59% (1149) cases had compliance, and 10.76% (183) did not apply to this parameters.

Conclusion:
According to this study, the compliance rate for prescription audit parameters is 67.59%, which should be improved by training staff regularly and holding large group meetings and internal audits. Small group meetings with experienced professionals of the organization can help in the constant maintenance of quality. It is also possible to automate the prescription creation process with software for at least the basic details. Finally, the study concludes this with the organization that needs to use its clinical pharmacy experts in the quality improvement process.
Surveillance of Health Care-associated Pseudomonas aeruginosa Infections in a Tertiary Care Teaching Hospital
Authors: Chauhan Yash , Trivedi Niyati 
Published: November 2023

Abstract

Background:
Among Gram-negative microorganisms, Pseudomonas aeruginosa is the most frequent causative pathogen in health care associated infection (HAI). P. aeruginosa infections are becoming more challenging to treat due to its innate as well as capacity to fast acquiring resistance to available antimicrobial agents (AMAs). There needs to be continuous surveillance to understand the sensitivity pattern as well as the clinical profile of the infections caused by P. aeruginosa.

Materials and Methods:
This was a prospective, observational, study conducted in various inpatient departments of a tertiary care hospital in India. Complete clinical and epidemiological profile of the patients, from whom P. aeruginosa was isolated as a causative organism, was recorded. Such patients were followed up daily till the outcome was achieved. The sensitivity of P. aeruginosa to various AMAs was noted. Data analysis was performed using suitable statistical tests.

Results:

P. aeruginosa was isolated from 103 clinical specimens during the study. Almost all the patients were diagnosed with HAI. With the most common being skin and soft-tissue infections. 41.75% of P. aeruginosa were multidrug resistant, with 25.24% being carbapenem resistant. The duration of hospitalization after isolation was 19.83 ± 5.79 days. Sixty-two patients were successfully treated and discharged from the hospital.

Conclusion:
A high prevalence of multidrug, especially carbapenem resistance among the P. aeruginosa isolates, has been observed, compromising the ability to choose efficacious empirical regimens, use of multiple high-end AMAs, and prolongation of hospitalization. Implementation of effective preventive and control measures along with antimicrobial stewardship strategies are urgently needed.
