Urbanisme et environnement dans l’enseignement de l’architecture à la veille de Mai 1968
Authors: Pinson Daniel
Published: March 2023

Jusqu’en 1967, l’urbanisme ne figurait que parmi les enseignements optionnels de la section architecture de l’École nationale supérieure des beaux-arts (Ensba). La réforme voulue par André Malraux se proposait d’y remédier. Au fil de réunions préparatoires largement ouvertes, l’urbanisme parviendra, avec l’architecte-urbaniste Michel Écochard, chargé d’une mission d’aménagement inédite de la Corse, à définir sa place, dans le voisinage, très conquérant, des sciences sociales, mais aussi de celui, plus prémonitoire, de l’environnement. Les difficultés de coordination avec les premières, ainsi que les tensions internes à l’Ensba, conduiront cependant à la démission de Michel Écochard, avant même que n’éclate Mai 1968.

Authors: Somashekhar S. P. , Saldanha Elroy , Pandey Kalyan , Kumar Rohit , Ashwin K. R.
Published: March 2023

Background:

Minimally invasive surgery in rectal cancer has gained prominence owing to its various advantages in surgical outcomes. Due to rapid adoption of robotics in rectal surgery, we intended to assess the pace in which surgeons gain proficiency using cumulative summation (CUSUM) technique in learning curve.

Materials and Methods:

This was a prospective study of 262 rectal cancer cases who underwent robotic-assisted low anterior resection and abdominoperineal resection (RA-LAR and RA-APR). Parameters considered for the study were console time, docking time, lymph nodal yield, total operative time and post-operative outcomes. We used Manipal technique of port placements and modified centroside docking for the procedure.

Results:

The mean age of our study was 46.62 ± 5.7 years, the mean body mass index (BMI) was 31.51 ± 3.2 kg/m2. 215 (82.06%) underwent RA-LAR and 47 (17.93%) underwent RA-APR. 2.67% of cases required to open during our initial period. We had three phases of learning curve, initial phase (11th case), plateau phase (29th case) and then phases of mastery (30th case onwards). Our mean total operative time reduced from 5.5 to 3.5 h (210 ± 8.2 min), console time from 4.5 to 2.9 h (174 ± 4.5 min) and docking time from 15 to 9 ± 1 min from 30th case onwards.

Conclusion:

RA surgeries for rectal cancer have got good oncological and functional outcomes in high BMI, male pelvis and low rectal cancers. Learning curve can be shortened with constant self-auditing of the surgeon and team with each surgeries performed, reviewing the steps and by improving techniques.
Laparoscopic management of an ileal lipoma presenting with massive gastrointestinal haemorrhage
Authors: Kumar Saket , Harisankar A. G. , Kumar Pankaj , Kumar Abhay , Parween Rana
Published: March 2023

Small bowel lipomas are benign submucosal neoplasm composed mainly of mature adipose tissue. Despite their rare occurrence, lipomas are the second most common benign tumour of the small intestine. These tumours are mostly small in size and remain clinically asymptomatic. However, larger lesions tend to be more symptomatic, presenting with complications such as intussusception, bleeding or obstruction. Definitive surgical or endoscopic intervention is indicated in such symptomatic lipomas. Herein, we describe a rare case of ileal lipoma presenting with ileo-ileal intussusception and a life-threatening haemorrhage that was managed by laparoscopic-assisted ileal resection.
Prospective analysis of 164 fires of da Vinci SureForm SmartFire stapler in oncological cases: Indian cohort of 76 consecutive cases
Authors: Somashekhar S. P. , Saldanha Elroy , Kumar Rohit , Pandey Kalyan , Dahiya Akhil , Ashwin K. R.
Published: March 2023

Background:

The application of robotic staplers in surgeries has increased in recent years. Robotic platform enhances ability of the surgeon to directly control and manoeuvre staplers to achieve required angulation and sealing within the confines of the thorax and pelvis. Hence, in this study, we intended to learn the effectiveness of the SureForm™ SmartFire™ technology stapling system in various oncological procedures.

Patients and Methods:

Prospective study of 76 patients who underwent robotic-assisted total oesophagectomy, gastrectomies, hemicolectomies, low anterior resection/abdominoperineal resection and lobectomies/metastasectomy for respective malignancies for 16 months. Internal data log of the da Vinci surgical system for reload colour, reloads used, clamp attempts and staple fires used during each procedure along with patient’s post-operative outcomes were recorded.

Results:

One hundred and sixty-four firings have been made in 76 cases, with the majority being green reloads (76.8%) and average reloads for radical cystectomy 3.5, lobectomies/metastasectomy 3.44 and oesophagectomy 2.55. None of the cases had incomplete firings and required force-fire activation. In forty per cent of cases, the robotic stapler had to pause for sequential compression and seal. Seventy per cent of anterior resection procedures had at least one firing >45° beyond the laparoscopy limit. Collectively 52% SureForm stapler fires in anterior resection with >45° angle of fire. None of the cases had bleed or leak.

Conclusion:

SureForm™ SmartFire™ robotic staplers can be used for various oncological surgeries with minimal peri-operative leak and bleeding and has better articulation in closed spaces. Further case-matched comparative studies with laparoscopic or handheld powered staplers would be required for useful operative decision-making and analyse the clinical outcomes.
Efficacy analysis of hybrid operating room-based laparoscopic cholecystectomy combined with intraoperative endoscopic retrograde cholangiopancreatography in the treatment of cholelithiasis combined with choledocholithiasis – A case–control study
Authors: Lv Shangdong , Wang Binfeng , Hu Peng , Shi Binyao , Zhang Wenlong , Wang Aidong
Published: March 2023

Objective:

The objective is to compare the therapeutic effects of laparoscopic cholecystectomy (LC) combined with intraoperative endoscopic retrograde cholangiopancreatography (ERCP) in hybrid operating room and ERCP + LC under traditional conditions in the treatment of cholelithiasis and choledocholithiasis.

Materials and Methods:

Data of 82 patients with cholelithiasis complicated with choledocholithiasis treated by our centre from November 2018 to March 2021 were retrospectively analysed. Amongst them, 40 patients treated with LC combined with intraoperative ERCP in a hybrid operating room were placed into Group A, and 42 patients treated with ERCP first followed by LC under traditional conditions were placed into Group B. The differences in operative time, intraoperative blood loss, surgical success rate, stone clearance rate, pain score, exhaust time, ambulation time, post-operative complications, length of hospital stay, hospitalisation cost and other indicators between the two groups were compared.

Results:

There were no significant differences in operative time, intraoperative blood loss, surgical success rate and stone clearance rate between the two groups (P > 0.05), while there were significant differences in post-operative pain score, exhaust time, ambulation time, length of hospital stay, hospitalisation cost and complications (P < 0.05).

Conclusion:

LC combined with intraoperative ERCP in hybrid operating room for the treatment of cholelithiasis combined with choledocholithiasis has a better therapeutic effect than traditional ERCP followed by LC, which is worthy of further popularization. Notably, the reasonable selection should be made based on patients’ own conditions and hospital facilities.
A review of the first 100 robotic cholecystectomies with a new cart-based surgical robot at a tertiary care centre
Authors: Chowbey Pradeep , Dewan Abhimanyu , Sharma Anil , Khullar Rajesh , Soni Vandana , Baijal Manish
Published: March 2023

Background:

Robotic cholecystectomy appears to be a natural evolution of the well-established gold standard procedure for gallstones, namely laparoscopic cholecystectomy. Akin to the early days of laparoscopy, robotic surgery is associated with a learning curve. We present our experiences in adapting to robotic surgery after the first 100 robotic cholecystectomies at a minimal access surgery tertiary care hospital.

Material and Methods:

The first consecutive 100 robotic cholecystectomies performed by a single surgeon on the Versius robotic surgical system (CMR Surgical, UK) were included in the study. Patients unwilling to give consent and complex pathologies such as gangrene, perforation and cholecystoenteric fistulas were excluded from the study. Operative time, robotic setup time, incidence and indication for conversion to manual (laparoscopic) procedure were recorded while subjective assessment of interruptions due to machine alarms and errors was made. All data were compared between the first 50 and last 50 procedures.

Results:

Our data revealed a gradual reduction in operative time from 28.53 min for the first 50 procedures to 22.06 min for the last 50 procedures. An improvement in draping and setup times was also noted, reducing from 7.74 to 5.14 min and 7.96 to 5.32 min, respectively. There were no conversions during the last 50 procedures, though the first 50 procedures resulted in 3 conversions to a laparoscopic procedure. In addition, we also noted a subjective reduction in the incidence of machine errors and alarms as we became more versed with the robotic system.

Conclusion:

Our single-centre experience indicates that newer modular robotic systems present a rapid and natural progression for experienced surgeons looking to venture into robotic surgery. The well-established advantages of robotic surgery in the form of enhanced ergonomics, three-dimensional vision and improved dexterity are validated as indispensable aids in a surgeon’s armamentarium. Our initial experience reveals that robotic surgery for more common surgical procedures such as cholecystectomies will be rapidly accepted, safe and effective. There is a need to innovate and expand the range of instrumentation and energy devices available.
Sestamibi-guided thoracoscopic excision of functional mediastinal parathyroid adenoma in a child: A case report and review of literature
Authors: Sahu Avilash , Zameer M. M. , Rao Sanjay , D’Cruz Ashley
Published: March 2023

Primary hyperparathyroidism secondary to ectopic parathyroid (in anterior mediastinum) is rare in children. We report the case of a 12-year-old girl with a history of multiple fractures, renal calculi and limb deformities. She was diagnosed with hyperparathyroidism secondary to an intrathymic parathyroid adenoma. Sestamibi scan showed a lesion in the anterior mediastinum. A biochemical evaluation revealed hypercalcaemia, elevated alkaline phosphatase and parathormone levels. The lesion was marked with radioisotope and confirmed intraoperatively using a gamma camera. The child underwent thoracoscopic left thymectomy with the adenoma. Immediate decrease in calcium and parathyroid hormone values were noted intraoperatively and serial monitoring showed a downward trend. On follow-up, the child is doing well. Ectopic parathyroid adenoma is very rare. CT with radioisotope scans is helpful in diagnosis. Thoracoscopic excision of ectopic adenoma is safe in children.
A case report of subconjunctival emphysema as a rare complication of pulmonary resections
Authors: Sarbay Ismail , Turna Akif
Published: March 2023

Lung volume reduction surgery (LVRS) is performed to the selected patients with lung emphysema who have higher residual volume, restricted pulmonary functions and limited diaphragmatic movement. Post-operative prolonged air leak is not uncommon following LVRS due to pulmonary emphysema. In some patients with prolonged air leak, pneumoderma may develop. Subconjunctival emphysema is a bizarre and very rarely seen complication. We report a patient suffering from subconjunctival emphysema after an LVRS along with a diagnostic wedge resection for a suspected pulmonary nodule which was revealed to be a large cell neuroendocrine carcinoma. The condition was resolved with conservative management with no visual impairment. He has been doing well and tumour free for 38 months.
Veress needle insertion simulation model: A simple new module for advanced surgical skill training
Authors: Durchholz William , Shea Connor , Kronner Daniel , Tuma Faiz
Published: March 2023

Introduction:

Training on Veress needle (VN) insertion cannot be done by observation without practicing tactile feedback. In this study, a simple and reproducible VN insertion training model was created. The aim of this study was to evaluate the validity of using the proposed model in simulating actual real-life surgical experiences.

Methods:

The proposed VN insertion training model is made of three layers of synthetic rubber and plastic materials, simulating the tensile strength and texture of the three abdominal wall muscle layers. Surgeons and senior residents with experience in minimally invasive procedures were asked to practice VN insertion on this model, each completing the procedure three times. Participants were then asked to record their comments and answer six questions regarding their experience practicing on the model.

Results:

Ten surgeons and four senior residents participated in this study. All participants agreed or strongly agreed that the model simulates the surgery experience regarding the shape and overall structure, tactile feedback and confirmation of complete/successful insertion. Twelve participants (86%) agreed or strongly agreed that the pressure/force needed for VN insertion was like real surgery experience and that the overall experience with using this model is similar to the real surgical experience. Almost all participants (93%) agreed or strongly agreed that the model is a valuable resource for training before practicing the procedure on real patients.

Conclusions:

The VN insertion training model provides a valuable training opportunity on a demanding surgical skill. It is simple, reproducible and closely simulates surgery.

Published: March 2023

Objective:

This study aimed to analyse the learning curve (LC) in laparoscopic rectal cancer resections of 2 millennial surgeons during the implementation of the first laparoscopic rectal cancer surgery programme in low- and middle-income country (LMIC) cancer centre.

Methods:

All consecutive patients operated by two millennial surgeons for primary rectal adenocarcinoma between January 2018 and March 2020 were included. The LC was analysed for operative duration and conversion to open surgery using both cumulative sum (CUSUM) and/or variable life-adjusted display (VLAD) charts.

Results:

Eighty-four patients were included, 45 (53.6%) men with a mean age of 57.3 years. Abdominoperineal resection was performed in 31 (36.9%) cases and resections were extended to other organs in 20 (23.8%) patients. Thirteen patients (15.5%) had conversion to open surgery. Using CUSUM, Learning curve based on conversion was completed at 12 cases for the first surgeon versus 10 cases for the second. While using VLAD and learning curve-CUSUM (LC-CUSUM), the cases needed were 26 vs 24 respectively. The median operative duration was 314 min with a LC completed at cases (17 vs. 26), and (18 vs. 29) using, respectively, standard and LC-CUSUM.

Conclusions:

This study shows a safe and short LC of millennial surgeons during the implementation of a laparoscopic rectal cancer surgery in an LMIC cancer centre, and the valuable use of modern statistical methods in the prospective assessment of LC safety during surgical training.

Authors: Alfaidi Raghad Ahmed , Aljdani Maha Saleh , Magliah Sultan Fahad , Farahat Fayssal M , Jaber Tariq Mohammad
Published: March 2023

Background and Aim:

The prevalence of type 2 diabetes mellitus (T2DM) and obesity and the associated direct healthcare costs have been increasing worldwide. Several bariatric surgical procedures, which have successfully resulted in body weight loss, were found to be superior to conservative therapies in managing T2DM. We aimed to assess the effect of laparoscopic sleeve gastrectomy (LSG) on the direct cost of antidiabetic medications among adult T2DM patients in Saudi Arabia.

Materials and Methods:

Following a retrospective chart review, this study included all adult T2DM patients with a body mass index (BMI) ≥ 35 kg/m2 who underwent LSG between January 2015 and June 2018 at King Abdulaziz Medical City in Jeddah. Patient files were reviewed at baseline, and 6 and 12 months postoperatively.

Results:

This study included 83 patients (mean age = 44.0 ± 10.9 years; men = 50.6%). BMI significantly decreased (P < 0.001) from the time of surgery (42.7 ± 6.4 kg/m2) to 6 and 12 months postoperatively (32.7 ± 6.2 kg/m2 and 29.7 ± 5.6 kg/m2, respectively), as did the glycosylated hemoglobin values (7.6% ± 1.6%, 6.0% ± 0.9%, and 6.1% ± 1.3%, respectively, P < 0.001). Overall, T2DM patients saved 1479 (95% confidence interval: 1053.75–1904.24) Saudi Riyal on their medications on their first-year post-LSG.

Conclusions:

LSG was effective in the management of T2DM in patients with obesity. Within 1 year postoperatively, it was associated with significantly improved diabetes control and reduced antidiabetic medication costs.

Background:

Literature evidence on periodontal disease-associated microorganism in pre-and postmenopausal women suggest a complicated relationship between steroid hormones, periodontal tissues, and microorganism.

Aim:

The objective of the study was to assess and contrast the periodontal health condition and quality of life (QoL) of pre-and postmenopausal women.

Materials and Methods:

100 patients were divided into four groups, i.e., healthy pre-menopausal, periodontitis pre-menopausal, healthy post-menopausal, and periodontitis post-menopausal. Periodontal parameters such as Gingival Index (GI), Plaque Index (PI), Probing Pocket Depth, Clinical attachment levels, Simplified Oral hygiene index, and a Utian QoL questionnaire were filled by the patients. The differences between three groups were analyzed using a one-way ANOVA test at baseline and 3 months, followed by a post hoc Tukey test.

Results:

The PI, GI, and Simplified Oral Hygiene Index levels were significantly different between healthy premenopausal and postmenopausal subjects. QoL scores were compared between the healthy premenopausal and healthy postmenopausal subjects, among which no statistically significant difference was found with P = 0.705 when compared between the positive questions score and P = 0.730 when compared between the negative questions score of the two groups.

Conclusion:

This study shows that there is no relation between menopause and QoL in women with periodontitis before and after menopause.

Background:

Parotid gland tumors are the most common major salivary gland tumors occurring in humans.

Aim:

This study aimed to evaluate the pattern of clinical presentation and management of parotid gland tumors in Northwestern Nigeria.

Materials and Methods:

In this retrospective study sociodemographics, nature of the lesion, fine-needle aspiration cytology result, surgical procedure, and complications of patients with parotid gland tumors were recorded and analyzed using SPSS version 25.

Results:

There were 31 (45.6%) males and 37 (54.4%) females in the age range of 17–72 years with a mean ± standard deviation of 49.03 ± 15.61 years. Benign tumors constitute the majority 50 (73.5%), with pleomorphic adenoma being the most common 46 (67.6%), whereas malignant tumors were 18 (26.5%), with adenoid cystic carcinoma being the most common 6 (8.8%). Superficial parotidectomy was the highest surgical procedure performed in 42 (70.6%) patients. Selective neck dissection was done in 5 (27.8%) cases and soft tissue reconstruction with deltopectoral flaps in 3 (16.7%) of the malignant cases. Transient facial nerve paralysis was seen in 14 (29.2%) and 8 (47.1%) of patients who had superficial and total parotidectomies, respectively. Permanent facial nerve paralysis was seen in all 5 (27.8%) patients who had radical parotidectomy.

Conclusion:

Pleomorphic adenoma was the most common parotid gland tumor, and superficial parotidectomy was the major surgical procedure performed. Facial nerve paralysis is an inevitable complication but can be minimized with meticulous surgical maneuver.

Authors: Prabhakar Praveena , Mahendra Raj R. R. , Saravanan Thalaimalai , Ramalingam Shakila
Published: March 2023

Background:

In completely edentulous patients, it is necessary to replace the teeth with at most esthetics and comfort with less patient strain.

Aim:

The current retrospective study was done to find the relationship between the intercondylar distance and intercanine distance of the mandible by obtaining the ratio using an orthopantomogram (OPG) for lower anterior teeth selection in completely edentulous patients.

Materials and Methods:

The OPG of 500 subjects was selected randomly. The OPGs were taken using the Sirona Orthophos XG machine and exposed for 14.1 s at 64 kvp, 8 mA. Then, the intercondylar distance and mandibular intercanine distance were measured from the soft copy of the OPG using the software “Sidexis.” The required measurements were taken digitally from the OPG using the software “Sidexis” in millimeters (mm). The SPSS software version 22.0 was used for statistical analysis.

Results:

Pearson correlation coefficients (r) displayed a significant positive association between the intercondylar distance and intercanine distance of the mandible (r = 0.42; P = 0.0002). The correlation between intercondylar width and mandibular intercanine width was significant and positive for men (r = 0.26, P = 0.0003) but negative for women (r = −0.41, P = 0.0001). The ratio between the mean intercondylar width and the mean intercanine width was 1:4.90.

Conclusion:

The mandibular intercanine distance and the intercondylar distance have a positive and significant association. The ratio obtained in this study was 1:4.90 between the mandibular intercanine distance and the intercondylar distance that could be employed for the choice of mandibular anterior teeth.

Effect of two different antifibrinolytic agents on platelet-rich fibrin
Authors: Ponnusamy Vishnu , Nalini H. Esther , Devi R. Renuka , Raja Nivetha
Published: March 2023

Background:

Platelet-rich fibrin (PRF) is a potent autologous regenerative material used in periodontal regeneration. PRF collapses easily into the periodontal defect due to its faster resorption rate and lesser rigidity. The degradation time of PRF has a direct impact on the clinical outcome.

Aim:

This study aimed to compare and analyze the effect of two different antifibrinolytic agents on the degradability of PRF membranes.

Materials and Methods:

Twenty-one PRF membranes were randomly divided into three groups: Group 1 – Conventional PRF obtained by adding normal saline (Control), Group 2 – PRF obtained by adding 200 mg tranexamic acid (TXA), and Group 3 – PRF obtained by adding 250 mg epsilon aminocaproic acid (EACA). After storing at room temperature in normal saline, PRF membranes were retrieved at 1st, 2nd, and 3rd weeks and the percentage of remaining weight was calculated. ANOVA is used for the statistical comparison of the data between groups.

Results:

In comparison to the baseline, the mean PRF weight was decreased in all groups in the 1st, 2nd, and 3rd weeks. In the 1st, 2nd, and 3rd weeks, the mean percentage of the remaining weight of PRF membrane in Group 1, Group 2, and Group 3 were 69.53 ± 12.96, 36.23 ± 9.28, and 17.43 ± 4.75 respectively. The statistical significance with the percentage of the remaining weight of the PRF was obtained in 3rd week with a P = 0.029.

Conclusion:

TXA efficiently delayed the degradability of the PRF membrane compared to EACA under experimental conditions.

Authors: Srinivedha C. V. , Bansal Adity , Chug Ashi
Published: March 2023

Introduction:

Kindler syndrome is an autosomal recessive disorder with multisystem involvement such as cutaneous, oral, gastrointestinal, and urogenital manifestations.

Rationale:

Timely diagnosis and management of this syndrome are warranted. The dental surgeon has a prime role in diagnosing the same and halting the progression of gingivitis to periodontitis and referring the patient to appropriate specialists for effective and timely management of the same.

Patient Concerns:

In this case report, a 17-year-old patient had reported with the chief complaint of spontaneous bleeding from gums and swollen gums since birth, and blackish pigmentation of the skin.

Diagnosis:

On examination, the patient had poikiloderma, photosensitivity, gingival fragility, and skin atrophy suggesting a diagnosis of Kindler syndrome.

Interventions:

Oral prophylaxis was done for the patient on several sittings and the patient was on continuous follow-up for 2 years. Dermatology and urology opinions were sought and advice was followed.

Outcomes:

The patient had complete regression of spontaneous gingival bleeding and oral hygiene had also become satisfactory.

Lesson:

Prompt diagnosis of the disease with appropriate and early intervention by a dental surgeon could definitely stop the disease progression.
Enamel island technique and nonrigid connectors
Authors: Bahri Maj Rahul , Prakash Poonam
Published: March 2023

Rationale:

Fixed denture prosthodontics is a commonly practiced treatment option for rehabilitation of partially edentulous clinical conditions. Certain local and systemic factors contraindicate utilization of implant therapy. Long edentulous span, pier abutment, distal abutments, and intersegment prosthesis extending from one sextant to another are a few challenging situations due to altered biomechanics and require modification in treatment planning to achieve optimum outcome.

Patient Concerns:

A 37-year-old male patient reported with difficulty in mastication due to partially edentulous mandibular arch.

Diagnosis:

Based on clinical features, a diagnosis of Class II partially edentulous mandibular arch was made.

Intervention:

Rehabilitation of partially edentulous mandibular arch was done using customized semiprecision attachment.

Outcomes:

Recall appointments were scheduled at 48 h, 1 week, 1 month, and 3 months and the patient was found to be satisfied with the prosthesis.

Lessons:

Semiprecision attachment is a viable modality that is used in rehabilitation of pier abutment situations. It protects the abutment from unwanted leverage forces and ensures longevity of the restoration.
1D crustal structure of Albania region
Authors: Dushi Edmond Dhimitraq , Havskov Jens
Published: March 2023

A new crustal 1D layered model for Albania has been determined. The data used consist of P and S readings from 108 evenly distributed and well located earthquakes using the Albanian Seismic Network and nearby seismic stations. The method used was to relocate the data using many thousand models, which were varied in a systematic way in a wide range around a start model determined from currently available models. The model with the lowest average travel time residual RMS was then selected as a final model. Tests with synthetic data showed this to be a robust method. With the dataset, the average RMS was reduced from 0.69s, using the current model, to 0.56s using the start model and to 0.49s using the final model. The new hypocenters were also found to be closer to a set of well located ISC hypocenters than the original locations. The final model found is: Depth to interface (km)          P-velocity (km/s)             0                                              5.5             12                                            6.0             23                                            6.3             41                                            7.7 with a Vp/Vs=1.81. This final model is different from the currently used model in Albania and should therefore represent a significant improvement for earthquake location.

This paper investigates the influence of bath pH values on the structural and optical properties of magnesium oxide (MgO) thin films synthesized using electrodeposition technique. The films were deposited on conductive fluorine tin oxide (FTO) substrates using magnesium nitrate hexahydrate as a precursor material. The structural, morphological and optical properties of the electrodeposited films were examined by scanning electron microscopy (SEM), X-ray diffraction and UV-Vis spectrophotometer. The morphology and optical properties of the films were found to vary with bath pH values. The band gap decreased as the bath pH values increased. The deposited MgO films exhibited average transmittance of 80%, 50%, and 25% with thicknesses 400 nm, 480 nm, and 540 nm for bath pH values of 2.0, 5.0, and 9.0, respectively. The results obtained indicate that bath pH values play significant role in the formation of MgO films and can be used to tune the material into useful optoelectronic applications.

Authors: Şenol Ahmet Kayra , Sayın Şakul Ayşe Arzu
Published: March 2023

There is an ongoing interaction between nutrition, immune system, and infectious diseases. Inadequate and unbalanced nutrition may reduce the defense efficiency of the immune system and increase the risk of contracting infectious diseases and the severity of disease symptoms. COVID-19 (coronavirus disease-2019) outbreak, which emerged in December 2019 and was declared a pandemic by the World Health Organization (WHO) in a short time, has become the most important public health problem worldwide in the last few years. COVID-19 is asymptomatic or causes with mild symptoms in most people, however, it progresses to severe illness accompanied by serious symptoms in some people, and it is known that this difference is mainly related to the effective immune responses of individuals. There is currently any easily accessible antiviral drug with proven therapeutic efficacy for the prevention and treatment of COVID-19 disease. Therefore, there has been an increasing effort to explore immune-supportive additional therapeutic options to strengthen the immune system and reduce disease-related complaints. The innate immune response, which is responsible for preventing transmission and invasion in the early stages of viral infections, is the first line of defense to eliminate the virus, and it is critical in the effective and balanced activation of the adaptive immune response. Therefore, the use of antimicrobial and antioxidant minerals, vitamins, medicinal plants, and probiotics that will strengthen the immune response is one of the accessible, easily applicable, and effective preventive measures. In this review, the effectiveness of therapeutic and supportive nutritional supplements against COVID-19 disease, which has become a major problem worldwide, has been discussed.

Authors:   Bulgarian Academy of Sciences, Institute of Mathematics and Informatics and Institute of Inormation and Communication Technologies: Sofia, BG, Todorov Venelin
Published: March 2023

Monte Carlo method is the only viable method for high-dimensional problems since its convergence is independent of the dimension. In this paper we implement and analyze the computational complexity of the Latin hypercube sampling algorithm. We compare the results with Importance sampling algorithm which is the most widely used variance reduction Monte Carlo method. We show that the Latin hypercube sampling has some advantageous over the importance sampling technique.

This qualitative research study looks at how reflective practices support preservice teachers’ professional growth and development and its impacts on their self-efficacy. This study takes place in a regionally recognized south-western Hispanic Serving Institution that serves a high needs school district. Preservice teachers were asked to reflect on their field experiences to integrate theory and practice. The common themes that emerge contend that preservice teachers with a high sense of self efficacy maintain a better understand of classroom management with its connection to building relationships. Another significant finding indicates that preservice teacher’s reflective practices lead to self-efficacy and professional growth.

Authors: Small Evan , Varker Frannie
Published: March 2023

Understanding, complexifying, and co-generating space for critique, growth, and transformation through experiential education informs and helps re-imagine education in more equitable ways. Through a critical lens, critical experiential education offers the potential to engage students and educators alike in putting what educators re-imagine education to be into practice. A more equitable educational system calls for transforming our world into communities that are more generous, liberatory, kind, engaged, and appreciative of difference. The work of building these communities is the work educators and activists should focus on more now than ever in today's ever-changing and tumultuous world.
Think Globally, Travel Locally: Doctoral Program Travel for Inquiry, Equity, and Social Justice
Authors: Lawrence Sara , Lease Kathy
Published: March 2023

Real-world experience is often considered subordinate to academic learning at the doctoral level. Lessons from experiential learning at the doctoral level show higher education can be equity-minded and focused on the needs of learners without sacrificing depth and quality even at the highest levels of educational attainment. Doctoral faculty developed a travel experience providing doctoral students the opportunity to better understand themselves as leaders, broaden their understanding of the “other,” and bring current issues and trends to life through experiential learning provided by traveling together for a fleeting time and a short distance. The doctoral program is seeing the byproducts of the experience in the inquiry of doctoral students focused on issues of diversity, inequity, and sustainability intended to improve educational outcomes in our nation. While the potential for inequity and disparity to divide the cohort was real, providing the opportunity for all to participate with minimum struggles associated with group travel allowed the cohort to form a bond that has provided a greater level of peer support through the dissertation process. Travel activities and components that led to the success of the experience are discussed.
Fostering Resilience in Experiential Learning Courses
Authors: Hackey Robert
Published: March 2023

A focus on resilience in experiential education provides students in pre-professional programs opportunities to reflect upon their experiences as interns while also supporting their mental health and professional growth. Faculty must help students to identify strategies to manage stress and develop professional norms needed to thrive in a variety of work environments – whether in-person, hybrid, or remote. Capstone internship experiences offer an ideal setting to help students develop practical skills to support their personal and professional growth and identify their personal values and priorities. Field experience courses can foster student resilience by incorporating time for student journaling and reflection into all class meetings, encouraging students to identify strategies to forge a healthy work-life balance, and focusing on professional socialization by curating their online presence and mastering online collaborative tools such as Microsoft Teams that are vital elements of hybrid and remote work settings.

This trial investigated the effect of dietary Ginkgo biloba leaf (GBL) on the growth performance and nonspecific immunity of red swamp crayfish Procambarus clarkii. 180 Crayfishes were randomly divided into three groups. One group was fed with basic diet, whereas the other two groups were fed with diets containing 1% and 3% GBL. After 32 days of feeding, GBL addition tended to increase the body weight gain rate compared with control. In 3% GBL group, the bodyweight gain rate of male crayfish was higher than that of female crayfish. While female crayfish were advantageous in terms of meat yield. Liver-related indexes were influenced by GBL addition and 3% GBL could reduce glutamic pyruvic transaminase and glutamic oxaloacetic transaminase as well as total cholesterol in male crayfish, showing its function in liver protection. Moreover, GBL addition effects on liver protection was better in male crayfish than female crayfish.
