Introduction: The objective of the present study is to evaluate the various pelvi-calyceal anatomy related and stone related parameters and their influence on stone free rate in retrograde intrarenal surgery for lower calyceal stones. Methods: The retrospective analysis of records of 206 patients who underwent retrograde intrarenal surgery for lower calyceal stones from December 2021 and November 2023.The patients were divided into two groups: stone free group and residual stone group. Various factors like patients’ characteristics, stone size, volume, numbers, density, infundibular width, infundibulopelvic angle, operative time, lasing time, type of laser, and retreatment rate were compared between two groups. Results: The mean stone size in stone free group was 1.1 ± 0.7 cm whereas in residual stones group was 1.7 ± 0.4 cm ( p = 0.03). Overall stone free rate was 62.1% (128/206) whereas residual stone rate was 37.9% (78/206). In stone-free group only 2.3% (3/128) of the patients had an acute infundibulopelvic angle ⩽ 30° whereas in the residual stones group an acute infundibulopelvic angle ⩽ 30° was found in 58.9% (46/78) of the patients ( p < 0.001). Patients with an infundibulopelvic angle ⩽ 30°, 93.8% (46/49) had residual stones, whereas infundibulopelvic angle > 30° only 20.1% (32/157) had residual stones ( p < 0.001). Multivariate logistic regression analysis has demonstrated that Infundibulopelvic angle and stone size were the only significant factors in predicting stone free rate for lower calyceal stone. Conclusion: Infundibulopelvic angle and stone size have significant impact on the stone free rates in retrograde intrarenal surgery for lower calyceal stones.

Background Human papillomavirus (HPV) vaccination is one of the key preventative measures for cervical cancer, provided that effective vaccine uptake is employed. However, HPV vaccine uptake is low in settings with limited resources such as low- and middle-income countries. Objectives To assesses the uptake of HPV vaccine and associated factors among female students attending secondary schools in South West Shoa Zone, Oromia, Ethiopia, 2022. Methods A cross-sectional study was conducted in secondary schools of South West Shoa Zone between November 1st to November 30th 2022. A multi-stage sampling technique was employed among 634 female students attending secondary schools. Data were collected by self-administered structured questionnaires, entered into Epi-info version 7.2.2.6, and exported to SPSS version 25 for statistical analysis. Bivariable analyses were considered for Multivariable analysis. Adjusted odds ratio (AOR) along with 95% confidence levels were estimated to assess the strength of the association, and a P value <0.05 was considered to indicate statistical significance. Results The proportion of HPV vaccine uptake was 31.65% (95% CI, 25-38). Having adequate knowledge AOR = 8.51 (95% CI = 4.57-15.84), living in rural area AOR = 0.25 (95% CI = 0.15-0.42), having older sibling AOR = 4.07(95% = 2.50-6.63), mother’s educational level (Diploma and above) AOR = 4.08 (95% CI = 1.75-9.49), and secondary education AOR = 3.98 (95% CI = 1.87-8.48) were significantly associated with HPV vaccine uptake among female students attending secondary schools in South West Shoa Zone, Oromia, Ethiopia. Conclusions The study revealed that HPV vaccine uptake was very low among female students attending secondary schools in South West Shoa Zone, Oromia, Ethiopia. Adequate knowledge, having older sibling, living in rural area, and having mothers with higher educational level were significantly associated with HPV vaccine uptake. All concerned bodies should work jointly to enhance the uptake of HPV vaccination among female students.

Published: September 2024

Background: Short peripheral catheter (SPC)-associated complications occur frequently in hospitalised neonates. Few studies have reported the use of SPC care bundles in resource-limited neonatal units. Objective: To evaluate the impact of a SPC care bundle on SPC associated complications (infiltration, dislodgement, phlebitis) and catheter dwell time. Methods: We conducted a quasi-experimental study comparing neonatal SPC complications during a 2-month baseline and a 2-month intervention period, where a SPC care bundle was introduced including hand hygiene, insertion site antisepsis, nurse assistance during cannulation, IV insertion carts and IV securement dressings. Results: A total of 459 SPC days were observed in 223 neonates: 111 pre-intervention and 112 post-intervention (after SPC bundle implementation). Most neonates were preterm (208, 93.3%) with very or extremely low birth weight (133, 59.6%). SPC care bundle compliance was 43.8% for five bundle elements and 83.9% for four bundle elements. Most SPCs had unplanned removal within 48 h of insertion owing to infiltration or dislodgement (89/111 pre-intervention (80.2%) vs 90/112 post-intervention (80.4%); 0.974). No phlebitis was documented. The mean SPC dwell time was unchanged following bundle implementation (32.9 vs 34.2 h; p = 0.376). Conclusions: Infiltration and dislodgement occurred frequently necessitating replacement of four of every five SPCs. Despite moderate compliance with the SPC care bundle, the high rates of unplanned SPC removal and short duration of catheter dwell time were unchanged. Contribution: The SPC care bundle did not improve catheter dwell time; further research is needed to identify strategies to reduce unplanned SPC removal and extend catheter dwell time in hospitalised neonates.

Introduction: The best approach for total mesorectal excision (TME) remains controversial. Two recently described approaches are robotic TME (RTME) and transanal TME (TaTME). This systematic review and meta-analysis aimed to compare the outcomes between robotic surgery and TaTME in patients undergoing rectal cancer resection. Methods: We structured this systematic review and meta-analysis according to the Preferred Reporting Items for Systematic Review and Meta-analysis (PRISMA) guidelines 2020 and Assessing the Methodological Quality of Systematic Reviews (AMSTAR) guidelines. An electronic search of relevant literature was conducted on 20 May 2023. The protocol was registered in PROSPERO (CRD42023435259). Results: Eleven eligible nonrandomised studies were included in this study. The study included 2796 patients (RTME = 1800; TaTME = 996). The RTME group had a higher rate of complete TME. However, no significant differences were observed in mortality, morbidity, severe complications, operative time, conversion rate, anastomotic leak, hospital stay, CRM-positive resection margin, distal resection margin, number of harvested lymph nodes, abdominoperineal resection (APR) rate, or local recurrence between the RTME and TaTME groups. Conclusion: The RTME technique may ensure a higher rate of complete TME than TaTME. However, no significant differences were observed in most postoperative outcomes and oncological safety between the RTME and TaTME groups. Evidence does not conclusively favor one technique over the other, highlighting the need for additional randomized controlled trials to better define their roles in rectal cancer surgery.

Authors: Plaxco Allison P. , Kmet Jennifer , Smeltzer Matthew P. , Jiang Yu , Taylor Michelle , Nolan Vikki G. 
Published: September 2024

Background: Two monovalent mRNA vaccines, available in December 2020, were demonstrated to have high efficacy against both the original SARS-CoV-2 strain and variants circulating through the summer and into the fall of 2021. In the context of the Omicron/BA.1 variant, which was predominant from late fall 2021 into winter of 2022 in the United States, and subsequent Omicron subvariants that have been predominant thereafter, vaccine effectiveness of the monovalent mRNA vaccine option is attenuated. Objectives: We aim to investigate the relative effectiveness of the bivalent booster compared to the monovalent booster against SARS-CoV-2 infection in the 60 days following administration in Shelby County, TN. Design: This observational population-based cohort study utilizes COVID-19 surveillance data to identify adults who were vaccinated with a monovalent booster dose between August 1, 2022 and August 30, 2022 or a bivalent booster dose between September 1, 2022 and September 30, 2022. Both groups were followed for COVID-19 status for 60 days from their administration date. Methods: We calculated incidence rates with 95% confidence intervals and propensity-adjusted hazard ratios with 95% confidence intervals of COVID-19 diagnosis in the 60 days following administration of the booster dose between the bivalent group and the monovalent group. Stratified analysis was conducted by age group (18–34, 35–64, and 65+ years old). Results: The incidence of reported SARS-CoV-2 infection was substantially higher for those who received the monovalent booster, across age groups. Overall, we observed a 51% lower hazard of infection during the study period among those who received the bivalent booster, compared to the monovalent booster. Conclusion: These results support and extend prior findings that the bivalent booster dose may be more effective in preventing infection against the Omicron sub-variants of SARS-CoV-2.

Authors: Falchenberg Åsa , Andersson Ulf , Boysen Gabriella Norberg , Andersson Henrik , Sterner Anders 
Published: September 2024

Abstract
Introduction
Healthcare systems worldwide are facing numerous challenges, such as an aging population, reduced availability of hospital beds, staff reductions and closure of emergency departments (ED). These issues can exacerbate crowding and boarding problems in the ED, negatively impacting patient safety and the work environment. In Sweden a hybrid of prehospital and intrahospital emergency care has been established, referred to in this article as Medical Emergency Team (MET), to meet the increasing demand for emergency care. MET, consisting of physicians and nurses, moving emergency care from EDs to patients’ home. Physicians and nurses may encounter challenges in their healthcare work, such as limited resources for example medical equipment, sampling and examination, in unfamiliar varying home environments. There is a lack of knowledge about how these challenges can influence patient care. Therefore, the aim of this study was to explore the healthcare work of the METs when addressing patients’ emergency care needs in their homes, with a focus on the METs reasoning and actions.

Methods
Using a qualitative multiple case study design, two METs in southwestern Sweden were explored. Data were collected from September 2023 – January 2024 and consist of field notes from participant observations, short interviews and written reflections. A qualitative manifest content analysis with an inductive approach was used as the analysis method.

Result
The result of this study indicates that physicians and nurses face several challenges in their daily work, such as recurring interruptions, miscommunication and faltering teamwork. Some of these problems may arise because physicians and nurses are not accustomed to working together as a team in a different care context. These challenges can lead to stress, which ultimately can expose patients to unnecessary risks.

Conclusion
When launching a new service like METs, which is a hybrid of prehospital and intrahospital emergency care, it is essential to plan and prepare thoroughly to effectively address the challenges and obstacles that may arise. One way to prepare is through team training. Team training can help reduce hierarchical structures by enabling physicians and nurses to feel that they can contribute, collaborate, and take responsibility, leading to a more dynamic and efficient work environment.

Abstract
Objective
This study aimed to investigate the normal volumetric space and variations in the measurements of different landmarks in adults with different skeletal relations of the maxilla and the mandible based on CBCT data. The study also analyses these landmarks to locate any correlations.

Background
Numerous studies in orthodontics have found a relationship between orthodontic treatment and changes in the anatomy and function of the airway. Severe changes in airway morphology can cause breathing difficulties, lower quality of life, and even result in life-threatening conditions such as obstructive sleep apnoea. Consequently, orthodontic diagnosis and treatment planning require a thorough understanding of the airway space and its function.

Methods
The present retrospective study was conducted using CBCT records of 120 adult patients, containing 40 samples of each skeletal class (20 males and 20 females). The boundaries were defined for the 3 major regions: the nasopharynx, the oropharynx, and the hypopharynx. Various measurements were recorded across these regions, as well as selective cephalometric landmarks. The obtained data was used to calculate average and standard deviation, while regression analysis was used to evaluate correlations and t-test was used to test statistical significance of gender differences.

Results
The results demonstrate that skeletal Class III individuals exhibit a reduced airway volume in the nasopharynx compared to other groups, whereas skeletal Class II individuals displayed a diminished airway volume in the hypopharynx. A strong correlation was observed for Sella turcica parameters. There were no significant differences in skeletal parameters across genders. Nasopharynx cavity volume demonstrated significant differences between skeletal Class I–Class III as well as between skeletal Class II–Class III. Hypopharynx cavity volume also demonstrated significant differences between skeletal Class I–Class II and between skeletal Class II–Class III.

Conclusion
The major findings are the presence of a reduced nasopharyngeal volume in skeletal Class III malocclusions while skeletal Class II individuals displayed a diminished hypopharyngeal volume, making these critical areas to consider during the diagnostic and orthodontic treatment planning stages. This study also revealed a consistent correlation between Sella turcica parameters across various facial skeletal profiles, with skeletal Class II patients exhibiting a distinct pattern and skeletal Class I and Class III demonstrating an average relationship.

Authors: Hande Alka , Kalmegh Padmashri , Patil Swati , Sonone Archana , Pakhale Aayushi 
Published: September 2024

Abstract
Background
Fibrous dysplasia (FD) is a benign fibro-osseous lesion, a skeletal developmental anomaly of the bone-forming mesenchyme. The diagnosis of fibro-osseous lesions, particularly those of the jaw bones, poses significant challenges to clinicians and pathologists since it requires a correlation of clinical, radiological, histological, and surgical findings. Accurate and specific diagnosis is crucial as treatment modalities differ with different fibro-osseous lesions.

Methods
This retrospective analysis presents a case series of a rare condition of monostotic FD in the maxillofacial region affecting jaw bones diagnosed and/or treated over period of 10 years.

Results
Five cases of monostotic FD were diagnosed and treated between a period of 2013 and 2023. The cases from the 2nd to 8th decade were included in the analysis with equal involvement of males and females. Out of five cases, four cases were involving maxilla and 1 showed involvement of mandible.

Conclusion
FD is a rare entity affecting the jaw bones which often lead to disfigurement of face. Early detection is warranted to decrease potential complications. In addition, genetic analysis could help in understanding the occurrence in certain population.
Comparative analysis of factors and barriers intervening in research participation among romanian and international medical graduates from one romanian medical faculty across three generations
Authors: Pop Andreea Iulia , Lotrean Lucia Maria 
Published: September 2024

Abstract
Objectives
This study focuses on the factors that encouraged engagement in research activities, as well as the barriers that restricted their involvement, until the final year of study at Iuliu Hatieganu University of Medicine and Pharmacy Cluj-Napoca, Faculty of Medicine. The main objectives of this study are to investigate potential disparities in research culture and student engagement in various research opportunities between Romanian and international medical graduates, as well as to conduct an examination of the observed patterns across various graduating years (2021–2023).

Materials and methods
A cross-sectional investigation was conducted among graduate students of the Faculty of Medicine at the Iuliu Hațieganu University of Medicine and Pharmacy in Cluj-Napoca, Romania. From 2021 to 2023, all graduate students from the Romanian and international programs of the faculty were asked to participate in the study by filling out an anonymous online questionnaire. The final sample included 572 participants, of whom 392 were students from the Romanian section and 180 were students from international programs.

Results
Motivation and personal interest drive research engagement, according to over half of graduates. For over one-third of graduates, institutional elements like financial support and education also play a major role, as does the desire to enhance their curriculum vitae. More than 25% of graduates value community influence, 70% of graduates attended medical congresses, 12–15% presented papers at medical conferences, 23% wrote medical articles, 10–15% published at least one scientific paper in medical journals, and 20% participated in medical school research projects. Comparative analysis showed that Romanian students start research earlier, attend more medical conferences, present posters, collect data for studies, and are more interested in publishing graduation thesis data in scientific journals. To encourage international students to participate in research, the study found that colleagues’ examples were more important, and both time and funds were key barriers. The research also shows that 2022 and 2023 graduates will organize more scientific conferences. According to the study, 2022 graduates began their research earlier than others.

Conclusions
To increase student engagement in research activities, medical schools should prioritize the promotion of positive factors, minimize common barriers, offer customized support and resources, encourage collaborative research activities, and facilitate cross-cultural learning.

Published: September 2024

Abstract
Aim
Explore the mediating role of cognitive emotion regulation strategies used by nursing students between academic anxiety and procrastination. Design: A descriptive correlational design was used. Setting: This study was carried out in the faculty of nursing at the University of Alexandria. Sample: The participants in this study were all students enrolled in emergency nursing during the second semester of the academic year 2021–2022 and a convenience sampling of 654 nursing students. The Sobel test was used as a statistical method to determine the significance of a mediation effect by assessing whether the relationship between perceived academic anxiety and procrastination was significantly reduced when cognitive emotion regulation was included, using coefficients and standard errors from regression models to calculate the test statistic. Tools: Academic Anxiety Scale, Academic Procrastination Scale, and Cognitive Emotion Regulation Questionnaire were used to collect data.

Results
The study found that 46.5% of students reported high anxiety levels, with 40.1% perceiving moderate anxiety and only 11.3% experiencing low anxiety. Moreover, 80.4% of nursing students showed moderate academic procrastination. There is a positive correlation between procrastination and academic anxiety, with Adaptive and maladaptive coping strategies mediating this relationship, according to the Sobel test.

Conclusion
Based on the results, it can be concluded that there is a complex causal and effect relationship between academic anxiety and procrastination. Nursing students may resort to academic procrastination as a means of coping. Therefore, reducing anxiety, correcting maladaptive behaviors, and enhancing adaptive cognitive and emotional regulation strategies could effectively reduce academic procrastination.
