In many ways, volunteering has a positive impact on the development of a volunteer's personality and experience. This study aimed to evaluate the impact of health volunteering on improving the self-skills and practical capacities of students in the western region of the Kingdom of Saudi Arabia. Materials and methods: The study was a descriptive cross-sectional electronic web-based survey that was submitted on a web-based questionnaire; 183 students answered the survey, and then, the data were analyzed using SPSS. Results: This study shows that 95.6% of participants agree and strongly agree that the health volunteering experience was useful, 2.7% of the participants neither agree nor disagree, and 1.6% disagree and strongly disagree. Regarding the distribution of the participants on skills learned from volunteering experience, the largest proportion of student (36.1%) volunteers in the health sector acquired communication skills and the smallest proportion of student (14.8%) volunteers in the acquired time management skills. Regarding the disadvantages, 81.4% of the participants do not think there were any disadvantages to their previous health volunteering experience, while only 18.6% of them think there were any disadvantages to their previous health volunteering experience. Additionally, the study found that the type of the sector affects the skills acquired from health volunteering.

Research paper thumbnail of Monkeypox genome mutation analysis using a timeseries model based on long short-term memory

This virus can transmit from human to human through direct contact with respiratory secretions, infected animals and humans, or contaminated objects and causing mutations in the human body. In May 2022, several monkeypox affected cases were found in many countries. Because of its transmitting characteristics, on July 23, 2022, a nationwide public health emergency was proclaimed by WHO due to the monkeypox virus. This study analyzed the gene mutation rate that is collected from the most recent NCBI monkeypox dataset. The collected data is prepared to independently identify the nucleotide and codon mutation. Additionally, depending on the size and availability of the gene dataset, the computed mutation rate is split into three categories: Canada, Germany, and the rest of the world. In this study, the genome mutation rate of the monkeypox virus is predicted using a ...

It assesses radiology professionals’ challenges in accessing continuing medical education during the pandemic and recommends prospects for CME practices in radiology. Methods The data were collected from two predefined groups: radiographers and radiologists. The data were collected through an online survey conducted via Google Forms. A total of 215 radiographers and 65 radiologists participated. The data used in this paper were collected through an online survey administered from November 2022 to January 2023. The survey was structured into two sections. The first section gathered participants' demographic information, and the second section captured the participants' experiences with CME before and during the pandemic. The results showed that there had been a shift from face-to-face to online CME events since the outbreak of the COVID...

The final diagnosis of SA of the left knee was confirmed by a microbiology examination, which found Pseudomonas aeruginosa. The patient was treated with arthroscopic drainage and appropriate antibiotic therapy.

Research paper thumbnail of Assessment of Pancreatic Duct Dilation in Patients with Pancreatic Cancer and Chronic Pancreatitis using Ultrasonography: A Retrospective Study

Methods and Results: A retrospective study was conducted at King Fahad Medical City in Riyadh from December 2019 to March 2020 on the use of ultrasonography to assess PD in patients with PC and CP. The sample included 73 patients: 39 (21 females and 18 males) with PC and 34 (20 males and 14 females) with CP. The diameter of the main PD was measured by ultrasonography. The mean age for PC patients was 61.17±13.96 years, and for CP patients was 42.14±17.08 years (P=0.000). The diameter of the main PD in PC was 0.52±0.22 cm, and in CP, it was 0.51±0.28 cm (P=0.865). Our results suggest that the dilation of the PD is one feature that accompanies PC and CP. In our study, there was no significant difference in in the prevalence of dilation in both conditions (64.1% and 64.7%). Additionally, PC is 2.4 times more likely to be associated with diabetes mellitus than CP. Conclusion: PC occurs more commonly in the older age group, while CP occurs more commonly in the younger age group. Most cases of PC and CP were associated with dilation of the PD with no significant difference in the amount of dilation.

It is an autosomal recessive type of familial disease that is commonly associated with a history of consanguinity. We have documented this case of a 22-year-old adult male who came with acute right iliac pain; after an ultrasound scan and hormone investigations, he was diagnosed with polycystic ovarian syndrome (PCOS).

Methods and Results: The study included 36 (18 males and 18 females) young adult Sudanese with normal brain MRI. The MO volume was measured from a T1-weighted MRI in healthy young adult Sudanese using ImageJ software to determine the effect of age, sex, and body mass index (BMI) on the MO volume. The study found that the stereological volume of MO was 717.39±82.31 mm3 with significant differences between genders. The mean MO volume was greater in males than in females (769.2±54.2 mm3 and 665.7±73 mm3, respectively. P<0.001). There was an inverse, positive, moderately significant correlation between the age and MO volume (r=-0.341, P<0.05). In contrast, there was no significant correlation between BMI and MO volume (P>0.05) Conclusion: Our study detected a significant difference between genders in MO volume, w...
