Authors: Stonkutė Rima , Vansevičius Vladas 
Published: July 2024

Abstract
We have surveyed the complete extent of the disk of M33—a gas-rich low-mass dwarf spiral galaxy in the Local Group. The B-, V-, and I-passband (the Johnson–Cousins system) CCD images (typical seeing ∼0.″8) were obtained with the Subaru Telescope equipped with the Suprime-Cam mosaic camera. The wide-field (∼1.°0 × 1.°5) catalog of 803,095 (15 ≤ V ≤ 25) starlike objects, measured using the point-spread function and aperture photometry techniques, is presented. We determined the distance modulus of M33 using the tip of the red giant branch (I
TRGB = 20.64 ± 0.02) as a reference point of (m − M)0 = 24.63 ± 0.02stat ± 0.06syst (843 kpc). We found young (≲100 Myr) stellar populations residing up to the deprojected radius of ∼10 kpc. The scale length of the young main-sequence (MS) star surface-number density in the range of radial distances from 7 to 9 kpc is 0.53 ± 0.03 kpc. The youngest MS stars (≲15 Myr) reside up to the radius of ∼8 kpc. This distribution of stellar populations may suggest an outside-in scenario of recent star formation in the disk of M33.

L’autorité enseignante à l’épreuve de l’espace et du matériel : le cas singulier de l’EPS
Authors: Mayeko Teddy 
Published: July 2024

L’autorité d’un enseignant se bâtit dans l’exercice quotidien du métier. Relativement instable, elle s’éprouve et se construit dans la classe, au contact des élèves. À ce titre, l’EPS apparaît comme une discipline singulière, car elle propose aux acteurs (enseignant et élèves) des conditions de travail et d’apprentissage globalement éloignées des spatialités scolaires habituelles. Les repères matériels « classiques » (tables, chaises, tableau, etc.) disparaissent au profit d’autres artefacts (ballons, plots, chasubles, etc.) qui deviennent des objets incontournables du travail scolaire. Ainsi, cette contribution cherche à comprendre les fondements de l’autorité du professeur d’EPS. À travers une analyse comparative, elle met en avant l’importance des dimensions spatiales et matérielles. Le cas échéant, il semble que la proximité instaurée avec les élèves et l’usage que l’enseignant fait des objets pendant la leçon, déterminent des registres d’interaction plus ou moins compatibles avec la conduite de l’autorité.
Results of quadruple elastic nailing for length unstable fracture femur in pediatrics
Authors: Gaarour Osama S. , Abulsaad Mazen S. , Elkhouli Eslam H. , Abouelnas Bassam A. 
Published: July 2024

Background
Length-unstable shaft femur fractures including spiral, long oblique, and comminuted fractures are mechanically unstable under axial, bending, and rotational forces. The risk of shortening, rotation, and malalignment increases substantially with the standard technique using only two nails. Our study was the first to report the results of quadruple elastic nailing for length-unstable femoral fractures on a prospective basis. Moreover, our study was the first to correlate this technique to the operative time and to the radiation exposure time.

Patients and methods
In all, 26 patients with simple length-unstable pediatric shaft fracture femur were included from October 2020 to October 2022. We used four elastic stable intramedullary nails (ESINs) for fracture fixation. Operative time and radiation exposure time were calculated for each patient. Follow-up of union was judged by radiograph at 1, 2, 3, and 6 months postoperatively. The Flynn score was used for evaluation at the 6th month postoperatively.

Results
Most of the studied cases were associated with excellent outcomes (84.6%) with four cases being associated with satisfactory outcomes (15.4%). Entire cases were associated with full ROM with no recorded angular deformity or rotational deformity. The mean operative time, radiation exposure time, and full union duration were 1.23 ± 0.31 h, 1.26 ± 0.27 min, and 9.08 ± 2.78 weeks, respectively.

Conclusion
Our case series supports the use of ESIN in length-unstable diaphyseal femur fractures with 26 patients treated with a quartet of ESINs.
Early results of the combined grafting–cementation technique for the treatment of giant cell tumors with a large subchondral bone defect: a case series
Authors: Abdelaal Ahmed H.K. , Sleem Ahmed S.S. , Liodakis Emmanouil 
Published: July 2024

Background
Giant cell tumor (GCT) is a rare, locally aggressive bone tumor. It typically affects young adults close to the joints, mainly the knee joint. The high recurrence rate, along with erosion of the subchondral bone complicates the surgical plan. Current treatment standards involve extended curettage followed by space-filling by cement or graft. We present a detailed technique using a combined technique using both bone graft and cement for reconstructing GCT-related subchondral damage.

Patients and methods
Eighteen patients underwent surgery from January 2018 to December 2021. The surgery involved extended curettage using a high-speed burr, and lavage using hydrogen peroxide. Placement of the graft as a subchondral shelf helps to support the articular cartilage. Bone cement was applied to fill the cavity and support the graft; internal fixation was used in large-sized lesions.

Results
The mean follow-up is 34.5 months. Oncologically, local recurrence was reported in one case, with a distal radius location, and no distant metastasis was reported. Functionally, 86.6% had excellent/good Musculoskeletal Tumor Society score scores. Graft union had occurred in all cases; mean union time was 12 weeks. Rehabilitation included immediate passive range of motion exercises and partial weight bearing. The pain had improved significantly in all cases. Muscle power had been temporarily affected in five cases. One patient had a wound infection, managed with antibiotics.

Conclusion
Treatment of GCTs is challenging. The standard treatment involves curettage and gap filling. The presence of the cement close to the articular cartilage can lead to osteoarthritis due to different modulus of elasticity. We describe this combined technique to provide support, insulation, and stability, and minimize the stresses on the articular cartilage. The results of this technique are promising and yield good functional and oncological outcomes. Further research is needed to evaluate its long-term efficacy in preventing progressive osteoarthritis.
Closed-loop obstruction due to internal hernia: An atypical clinical presentation of acute abdomen — A case report
Authors: Chinta Varsha , Krishna Sunil M , Udupi Vivek Ramesh 
Published: July 2024

Abstract
Internal hernia is the protrusion of a viscus through a normal or abnormal peritoneal or mesenteric aperture within the confines of the peritoneal cavity. They can be congenital or acquired after abdominal surgery. We report a case of a 58-year-old woman who presented with complaints of abdominal pain and nonbilious vomiting for 2 days. She underwent an abdominal hysterectomy 15 years ago. After baseline blood investigations and imaging, a diagnosis of subacute intestinal obstruction was made. As she clinically worsened over 24 h, CT imaging was done, which suggested acute small bowel obstruction secondary to adhesions. Surgery revealed herniation with incarceration of distal ileal loops through a defect in the sigmoid mesocolon. Bowel resection was done, and the defect was closed. The clinical presentation of internal hernias, especially transmesosigmoid hernia, is nonspecific, and they rapidly progress to bowel ischemia. Early intervention and surgical correction are prudent for good clinical outcomes.

Authors: Zarei Ghasem , Mosleh Sorour , Zare Soraya , Abotalebi Mohammad Sadegh 
Published: July 2024

Abstract

Background:
Urinary retention is a postoperative problem that causes pain and discomfort for patients, even when catheters are used. The potential role of magnetic therapy in treating postoperative urinary retention through acupuncture points remains uncertain. This research aims to assess the impact of magnetic therapy on urinary retention in patients undergoing surgery.

Materials and Methods:
This single-blind clinical trial study was conducted in a recovery department within an operating room and subsequently in the Surgery Department of Amin Hospital. The study took place in Isfahan in 2022, with a sample of 64 patients selected using a simple random sampling method and divided equally into two groups. In the intervention group, magnet plates were applied, while the control group received iron plates at seven specific points for duration of 35 ± 5 minutes. Demographic information, the type of urinary excretion, the duration of urinary retention, and the volume of excreted urine were recorded using a researcher-made checklist for both intervention and control groups. These data were compared and subjected to descriptive and analytical statistical analysis.

Results:
Among the participants (N = 64), the majority were male (N = 37, 57.80%), and the mean age was 40.17 years. The Chi-square analysis revealed no significant difference between the intervention and control groups in terms of the type of urinary excretion (p = 0.106). However, the Mann–Whitney U-test demonstrated significant difference between the two groups regarding the duration required to eliminate urinary retention and the volume of excreted urine (F2,41 = 62 and F1,76 = 62; p < 0.001).

Conclusions:
The use of a novel approach involving magnetic therapy applied to acupuncture and reflexology points has been shown to reduce the time required for the first urination and increase the volume of urine in post-surgery patients.

Authors: Abbasi Mohammad , Asadoola Yousef , Ebrahimi Hossein , Bahonar Elahe , Dabirian Zinab , Esmaeili Seyed-Mahdi , Mahdizadeh Ahmad , Sadeghi Mahdi 
Published: July 2024

Abstract

Background:
The use of different educational methods and programs, such as simulation and virtual training, plays an important role in effective Cardiopulmonary Resuscitation (CPR) learning for nursing students. This study was conducted with the aim of comparing mannequin-based simulation training with virtual training on CPR learning among nursing students.

Materials and Methods:
This parallel randomized controlled trial was conducted in 2022. We selected 73 nursing undergraduate students and randomly assigned them to two groups: mannequin-based simulation and virtual training groups. The knowledge, attitude, and performance of CPR in both groups were evaluated and compared before, immediately after, and 1 month after the intervention. Data analysis was performed using independent t-test and the repeated-measure analysis of variance (ANOVA) using the Statistical Package for Social Sciences (SPSS) software.

Results:
Within-group differences were significant in both mannequin-based simulation and virtual training groups in terms of knowledge, attitude, and CPR performance before and after training, as well as between before and 1 month after training (p < 0.001). In addition, the mean performance of simulation group students was significantly higher than the virtual group (p < 0.001), but no significant difference was observed between the two groups in terms of knowledge and attitude dimensions before training, after training, and 1 month after training.

Conclusions:
Both mannequin-based simulation and virtual training methods increase CPR learning. Considering that students’ knowledge and attitude increase significantly using both training methods and the performance of students in the simulation group is better than in the virtual group, the use of a multimodal approach is recommended for CPR training of nursing students.

Published: July 2024

Abstract

Background:
This study is done to determine the translation and psychometric properties of the Persian version of Neonatal Intensive Care Unit Parental Belief Scale (NICU-PBS) in Iranian parents.

Materials and Methods:
The present study was conducted by the descriptive cross-sectional method. This research was conducted from January to August 2021. The population included all parents whose infants were hospitalized in NICUs of two university-affiliated hospitals (Kermanshah University of Medical Sciences and Shiraz University of Medical Sciences). Out of them, 291 subjects were selected by the purposeful sampling method. The utilized questionnaires included a demographic information form, NICU-PBS, Beck Depression Inventory, and Maternal role adaptation scale. The descriptive statistical indexes, Cronbach’s alpha, intra-class correlation coefficient, and Pearson’s correlation coefficient were used for data analysis. Also, to evaluate the construct validity of the NICU-PBS, we used Confirmatory Factor Analysis (CFA).

Results:
The participants included 97 fathers (33.33%) and 194 mothers (66.67%). According to the CFA results, the three-factor model NICU-PBS (confidence in the parental role, parent–child interaction, parental knowledge of the NICU) was approved in Iranian parents (χ2/df = 1.79; p < 0.001; GFI = 0.91; AGFI = 0.89; CFI = 0.91; RMSEA = 0.05). NICU-PBS with BDI-II (r = -0.42) has divergent validity, and material role adaptation (r = 0.46) has moderate and acceptable convergence validity (p < 0.01). The results of Cronbach’s alpha for the total NICU-PBS were 0.85.

Conclusions:
The results demonstrated the proper and acceptable validity and reliability of NICU-PBS among Iranian parents.
Laparoscopic versus open pancreaticoduodenectomy: Long-term outcome from a tertiary care centre
Authors: Kanchodu Sudheer , Rao H. T. Nagarjun , Mangyal Shivaraj S. , Ganesh M. K. 
Published: July 2024

Abstract

Introduction:
Laparoscopic Whipple’s pancreaticoduodenectomy (WPD) is one of the most advanced minimally invasive procedures. In recent years, with advancements in minimally invasive surgery, laparoscopic WPD has been increasingly adopted as a safe and feasible technique. This study aims to compare the short-term and long-term outcomes of laparoscopic WPD to open WPD in resectable ampullary, periampullary and head of pancreas malignancies.

Patients and Methods:
A retrospective analysis of a prospectively maintained database of patients who underwent WPD from January 2015 to January 2021 at the department of surgical gastroenterology in a tertiary care medical college hospital was conducted. Patient demographics and pre-operative details, intraoperative parameters (operating time and blood loss), post-operative length of hospital stay, median intensive care unit (ICU) stay, time to resume oral diet, post-operative complications, interventional procedures, mortality, 3-year survival, 3 year recurrence-free survival and overall survival were analysed.

Results:
Forty-two patients underwent WPD during our study period; 14 patients underwent laparoscopic WPD and 28 patients underwent open WPD. None required conversion. The majority of the patients had periampullary carcinoma in both the groups. Laparoscopic WPD showed a trend towards shorter ICU stays, hospital stays and surgical site infections (SSIs) compared to open WPD. The median operating time was significantly longer in the laparoscopic WPD group (380 min) compared to the open group (285 min). However, median blood loss was significantly lower in the laparoscopic group (250 mL vs. 300 mL). The pancreas-specific post-operative complications like delayed gastric emptying, post-operative pancreatic fistula or post-operative pancreatic haemorrhage did not differ significantly between the groups. All patients had R0 resection and the mean lymph node yield was comparable between the two groups (14.92 vs. 13.42). The reoperation rate or mortality rate did not show any statistical significance between the two groups. The overall survival was 46 months in the open group and 48 months in the laparoscopic group. Three-year survival was 74.1% in the open WPD group and 69.2% in the laparoscopic group. Three-year recurrence-free survival was 55.5% in the open group and 69.23% in the laparoscopic group.

Conclusion:
Laparoscopic WPD appears to be safe and feasible, with similar short-term and long-term survival outcomes. With a trend favouring laparoscopic WPD in terms of blood loss, hospital and ICU stay and post-operative SSIs, it should be offered to selected patients when the expertise is available.
An alternative combined revision of Roux-en-Y gastric bypass: Cover all aspects (of failure)!
Authors: Dalkılıç Muhammed Said , Yılmaz Merih , Gençtürk Mehmet , Erdem Hasan , Şişik Abdullah 
Published: July 2024

Abstract
The revisional surgical techniques for managing weight regain after laparoscopic Roux-en-Y gastric bypass have lacked a clear gold standard. Various methods such as pouch minimising, gastroenterostomy narrowing and distalization have been described, but none have consistently achieved optimal success. This study introduces a combined revision technique that enables the reassessment of both alimentary limb and biliopancreatic limb lengths based on the individual patient’s total bowel length. This approach aims to promote effective weight loss while minimising the pouch and gastroenterostomy.
Laparoscopic transection and partial resection of hernia sac in the treatment of indirect inguinal hernia: A preliminary observation
Authors: Dai Jinyu , Li Jian , Sun Xiaobing 
Published: July 2024

Abstract

Introduction:
This study aimed to investigate the feasibility of applying laparoscopic transection and partial resection of hernia sac in the treatment of indirect inguinal hernia in children.

Patients and Methods:
From December 2017 to November 2018, we recruited 20 children, who were aged 1–6 years old, with indirect inguinal hernia. At the time of admission, the participants had already developed an indirect inguinal hernia for 6 months to 1 year. A simple transection and partial resection of hernia sac was performed at the internal ring on each of the recruited children. The procedure was conducted under laparoscopy. Two 5-mm trocars were placed on either side of the umbilicus, one for the camera and the other for a surgical instrument. Another trocar was placed on the right abdomen. Laparoscopic camera curved forceps, and scissors were placed. Along the unclosed internal ring, the peritoneum was cut in a circular fashion to transect the hernia sac and dissociate it from the distal end. About 1–2 cm of the hernia sac was resected.

Results:
The operation was successfully completed in all 20 cases, who did not experience any complications, such as the absence of spermatic cord, vas deferens injury, scrotal swelling and incision infection. The children were discharged 1 day after the operation. In the post-operative follow-up for the first 3–4 years, recurrence and testicular atrophy did not occur in the study participants.

Conclusion:
The short-term results obtained from this study showed that the application of laparoscopic transection and partial resection of hernia sac in the treatment of indirect inguinal hernia is feasible. Long-term results and further observation are needed for validation.
Menstrual Cycle Changes after the COVID-19 Vaccine: A Cross-sectional Study in Saudi Arabia
Authors: Alshammari Hessah Fahan , Alrabiah Amal Humod , Shaheen Sameerah Yaseen , Mazi Sarah Ismail , Aljasser Rakia Suliman 
Published: July 2024

Abstract

Objective:
Various side effects of the COVID-19 vaccine, such as fatigue, have been reported. However, there has been a recent increase in reports of menstrual cycle changes among women. This study assessed the effect of the COVID-19 vaccine on the menstrual cycle of Saudi women.

Methods:
In this cross-sectional study, data were collected between November and December 2021 from 500 healthy Saudi females between 20 and 40 years. We included all women who reported having a normal menstrual cycle before being vaccinated against COVID-19.

Results:
A total of 65.6% of participants reported having significant changes in their cycle in terms of period timing, blood flow, and pain following the first and 65.6.% following the second COVID-19 vaccination doses. Both the mRNA and adenovirus vectored COVID-19 vaccines affected the cycle similarly. The induced COVID-19 vaccine menstrual cycle abnormality is a short-term effect lasting <3 months after the first and second doses.

Conclusion:
There are reported side effects of the COVID-19 vaccine; however, changes in the menstrual cycle have not been reported. Our study assumes that the menstrual cycle changes observed in the study’s participants were unlikely to be caused by reasons other than the COVID-19 vaccines, since we excluded all participants with medical interventions, medical conditions, and the age range that might affect the menstrual cycle. Although this effect is a short-term effect, the exact mechanism behind this phenomenon must be investigated.
