Assessment of Mental Foramen Characteristics in Syrian Population Using Cone Beam Computed Tomography: A Pilot Study.

Background Knowledge of the mental foramen (MF) characteristics is crucial for avoiding iatrogenic injuries during dental implant placement, root canal treatment, orthognathic surgery, and other dental and surgical interventions. Cone beam computed tomography (CBCT) offers a valuable tool for evaluating the MF characteristics with its precise anatomical details. The current study investigates the horizontal and vertical position variations in addition to the exit angle of MF within the Syrian adult population. Materials and methods The sample included CBCT scans of 42 subjects with an equal number of males and females (21 males, 21 females), with no underlying pathology in the investigated region, mean age was 24.7 years (SD: 7.2 years). CBCT scans were retrospectively analyzed in terms of the vertical, horizontal, and exit angle direction of MF. The chi-square test was conducted to investigate statistical differences in terms of MF horizontal and vertical positions. A T-test was conducted to investigate statistical differences in terms of exit angle direction. Comparisons were conducted between males and females groups, and between the left and right sides in the total sample group. Results The most frequent horizontal position was position 3 (MF between the first and second premolars) on the right side (n=20, 47.61%), and on the left side (n=21, 50%). The most frequent vertical position was position 3 (MF below the apices of the premolars) on the right side (n=29, 69.04%), and on the left side (n=27, 64.28%). The exit angle of the MF was in a backward direction, with a mean value of 118.42° (SD: 6.45 degrees), and 115.97° (SD: 7.29 degrees) on the right and left side, respectively. Statistically significant differences were found in terms of the right vertical position between males and females (P value < 0.05). Conclusion Variations in MF characteristics exist in the Syrian population. Statistically significant differences were found in the right vertical position of MF. The current study findings necessitate precise preoperative three-dimensional imaging for dental interventions among this population. By establishing normative values for the Syrian population, the results can contribute to improved surgical planning and patient care, and can be used for comparative studies for more understanding of the human anatomical variations.

Kiwifruit (Actinidia deliciosa) aqueous extract improves hyperglycemia, testicular inflammation, apoptosis, and tissue structure induced by Streptozotocin via oxidative stress inhibition.

Diabetes mellitus (DM) is a well-known hyperglycemic metabolic condition identified by oxidative stress and biological function disruption. Kiwifruit is a valuable source of polyphenols and vitamin C with great antioxidant, nutritional, and health-promoting effects. Therefore, this study was initiated to explore the antioxidant and anti-hyperglycemic effects of kiwifruit aqueous extract (KFE) against oxidative injury and testis dysfunction in rats with diabetes. Twenty-four male Wistar Albino rats (160-170 g) were divided into four groups: Group 1 served as the control, Group 2 supplemented orally with kiwifruit extract (KFE; 1 g/kg/day) for one month, Group 3 was treated with a single streptozotocin dose (STZ; 50 mg/kg ip), and Group 4 where the diabetic rats were administered with KFE, respectively. According to the results, the GC-MS analysis of KFE revealed several main components with strong antioxidant properties. In diabetic rats, lipid peroxidation and hyperglycemia were accompanied by perturbations in hormone levels and sperm characteristics. Antioxidant enzymes, glutathione content, aminotransferase, phosphatase activities, and protein content were decreased. Furthermore, histology, immunohistochemical PCNA expression, and histochemical analysis of collagen, DNA, RNA, and total protein. were altered in rat testis sections, supporting the changes in biochemistry. Furthermore, diabetic rats supplemented with KFE manifested considerable amendment in all the tested parameters besides improved tissue structure and gene expressions (NF-kB, p53, IL-1ß, Bax, IL-10, and Bcl2) relative to the diabetic group. In conclusion, KFE has beneficial effects as it can improve glucose levels and testis function, so it might be used as a complementary therapy in DM.

Differences in colorectal cancer awareness between screening eligible vs. ineligible Palestinians: a national cross-sectional study.

BACKGROUND: This study aimed to compare colorectal cancer (CRC) awareness between screening-eligible and ineligible individuals in Palestine. METHODS: Convenience sampling was utilized to recruit Palestinian adults from diverse settings, including hospitals, primary healthcare centers and public spaces across 11 governorates. The evaluation of CRC awareness in terms of signs/symptoms, risk factors and causation myths was conducted using Arabic-translated, modified versions of the validated instruments, the Bowel Cancer Awareness Measure and the Cancer Awareness Measure-Mythical Causes Scale. RESULTS: The final analysis included 2698 participants, with 2158 (80.9%) eligible for CRC screening and 540 (19.1%) ineligible for it. The most recognized CRC sign/symptom was 'lump in the abdomen' in both screening-eligible (n = 386, 71.5%) and ineligible (n = 1582, 73.3%) groups. 'Lack of physical activity' was the most recognized risk factor in both groups (eligible: n = 451, 83.5%; ineligible: n = 1766, 81.8%). The most reported causation myth in both groups was 'having a physical trauma' (eligible: n = 340, 63.0%; ineligible: n = 1353, 62.7%). In the screening-eligible group, only 210 participants (38.9%) demonstrated high awareness of CRC signs/symptoms, 213 participants (39.4%) showed high awareness of CRC risk factors and only 46 participants (8.5%) displayed high awareness of CRC causation myths. There were no significant associations between being eligible for screening colonoscopy and the awareness levels of CRC signs/symptoms, risk factors and causation myths. CONCLUSION: Overall, awareness levels of CRC signs/symptoms, risk factors and causation myths were notably low among screening-eligible participants. There were no differences in awareness levels between individuals eligible for colonoscopy and those who were not.

Prevalence and trends in physical therapy interventions for erectile dysfunction: A Scopus-based bibliometric analysis (1989-2022).

BACKGROUND: Erectile dysfunction (ED) is a condition that affects many males. Physical therapy (PT) is the one potential treatment for ED that may improve blood flow, muscle strength, and other factors that may contribute to the issue. Data on the prevalence and trends of research on PT for ED are lacking. OBJECTIVE: This study aimed to evaluate the literature trends in PT for ED via bibliometric and visualized analysis. METHODS: Data on publications were collected from Scopus covering the period between 1989 and 2022. To refine the data, bibliometric analyses were conducted using Microsoft Access, Microsoft Excel, an online visualization platform, and BiblioAnalytics. Power BI and Bibliomaster were used to generate figures and tables, while Biblioshiny and VOSviewer were used for visualization. RESULTS: A total of 494 documents were identified. The year 2019 generated the largest number of publications, with a total of 54. These studies have received 12,917 citations related to PT for ED. The most common document type was the original article with 283 publications. The University of California, USA, was the most productive institution on this topic, with 21 publications and 2,035 citations. The USA led all countries with 114 publications on the topic. The Journal of Sexual Medicine secured the top ranking with an h-index of 18. The main topics studied were erectile dysfunction, shockwave therapy, and physiotherapy. CONCLUSION: The number of publications on PT for ED has demonstrated an upward trend over the last three decades.

Superficial Temple Lymphatic Malformation Appeared 13 Years after Initial Presentation With Orbital Lymphatic Malformation.

A 26-year-old male with a history of orbital lymphangioma and compressive optic neuropathy presented with recurrent proptosis in the OS. After examination and imaging, a left orbital lymphatic malformation and a new subcutaneous temporal-parietal vasculo-lymphatic malformation were diagnosed. The patient underwent a bleomycin injection for the orbital malformation and an excisional biopsy for the temporal lesion, leading to symptom resolution. Recurrence of lymphatic malformations and hemorrhage typically occurs at the same site, here we report a patient with the appearance of a new site lesion with orbital recurrence.

Estimation of alpha exposure on CR-39 detector using a UV-VIS spectrophotometer.

This work is dedicated to study the possibility of using UV-VIS spectrophotometer, a non-invasive technique with a versatile applications that is being used to determine the optical properties of matter, to estimate the CR-39 exposure to alpha particles. CR-39 detectors were exposed to alpha particles from two different alpha sources: 241Am and radon gas. Tracks densities on CR-39 were determined using the traditional counting method by an optical microscope. The transmittances of CR-39 detectors were measured using UV-VIS spectroscopy in the range of 400-1000 nm, and results were correlated with measured tracks densities. The comparison showed that this method is effective in estimating exposure of CR-39 to alpha particles, and that its efficiency has increased by increasing the etching time of the detectors.

Knowledge and Preparedness of Physicians in Relation to Anaphylaxis at Primary Healthcare Centers in Al-Qassim, Saudi Arabia.

Background Anaphylaxis is a significant, often fatal, systemic allergic reaction with a rapid start that may affect the respiratory and/or circulatory systems; for patients to survive, emergency management must be done properly. When anaphylaxis is confirmed or highly suspected, epinephrine should be injected intramuscularly. This study aimed to assess the preparedness of primary healthcare physicians for anaphylaxis in terms of recognition and management of this condition in Al-Qassim, Saudi Arabia. Methods This cross-sectional study was carried out among primary healthcare physicians in the Qassim region of Saudi Arabia. A self-administered questionnaire was distributed among the targeted physicians. The questionnaire comprised sociodemographic characteristics, general awareness and management of anaphylaxis, and a 10-item questionnaire to assess physicians' knowledge of anaphylaxis. Results Out of 121 primary healthcare physicians, 61.2% were male, and 47.9% were aged between 25 and 35 years. Nearly all physicians (97.5%) believed that anaphylaxis is a life-threatening situation. The overall mean knowledge score was 4.74 out of 10 points. Nearly half (48.8%) were categorized as having poor knowledge levels, 43% as moderate, and only 8.3% as having good knowledge. Being specialists/consultants and being trained in managing anaphylaxis were the factors associated with increased knowledge. Conclusion The knowledge of primary care physicians regarding anaphylaxis was deficient. However, increased knowledge of anaphylaxis was seen more frequently among consultants or specialists who attended training for managing anaphylaxis cases. A multi-center study involving a bigger sample size is needed to establish physicians' knowledge of anaphylaxis.

Dynamic cerebral autoregulation is preserved during orthostasis and intrathoracic pressure regulation in healthy subjects: A pilot study.

Resistance breathing may restore cardiac output (CO) and cerebral blood flow (CBF) during hypovolemia. We assessed CBF and cerebral autoregulation (CA) during tilt, resistance breathing, and paced breathing in 10 healthy subjects. Blood velocities in the internal carotid artery (ICA), middle cerebral arteries (MCA, four subjects), and aorta were measured by Doppler ultrasound in 30° and 60° semi-recumbent positions. ICA blood flow and CO were calculated. Arterial blood pressure (ABP, Finometer), and end-tidal CO2 (ETCO2) were recorded. ICA blood flow response was assessed by mixed-models regression analysis. The synchronization index (SI) for the variable pairs ABP-ICA blood velocity, ABP-MCA velocities in 0.005-0.08 Hz frequency interval was calculated as a measure of CA. Passive tilting from 30° to 60° resulted in 12% decrease in CO (p = 0.001); ICA blood flow tended to fall (p = 0.04); Resistance breathing restored CO and ICA blood flow despite a 10% ETCO2 drop. ETCO2 and CO contributed to ICA blood flow variance (adjusted R2: 0.9, p < 0.0001). The median SI was low (<0.2) indicating intact CA, confirmed by surrogate date testing. The peak SI was transiently elevated during resistance breathing in the 60° position. Resistance breathing may transiently reduce CA efficiency. Paced breathing did not restore CO or ICA blood flow.

Retrospective analysis of pediatric sepsis and the burden of antimicrobial resistance in Duhok, Kurdistan Region of Iraq.

Introduction: Sepsis is a life-threatening complication in pediatric patients. This study primarily aimed to investigate sepsis-causing bacteria and their antimicrobial resistance profile and check the change in the antimicrobial resistance trend for some selected bacteria. In addition, we evaluated the incidence of sepsis, the related mortality rate, and the effectiveness and outcome of the treatment regimes in sepsis pediatric patients. Methods: A retrospective analysis was conducted on 4-year data (2018-2021) collected from three intensive care units at the Hevi Pediatric Teaching Hospital. Sepsis screening involved clinical detection and confirmation by blood culture. Results: A total of 520 out of 1,098 (47.35%) blood samples showed positive microbial growth. A decrease in sepsis rate was observed during the COVID-19 pandemic. Coagulase-negative Staphylococci (CoNS) and Klebsiella pneumonia were the most commonly isolated bacteria. A notable variation in the antimicrobial resistance trend was observed among sepsis-causing bacteria. The empirical sepsis treatment recommended by the WHO was ineffective, as certain bacteria exhibited 100% resistance to every antibiotic tested. The mortality rate significantly increased from 1.3% in 2018 to 16.5% in 2021. Discussion: The antimicrobial resistance profile of sepsis causing bacteria is of concerns, indicating a potentially serious situation. Thus, to avoid treatment failure, the monitoring of antimicrobial resistance in pediatric patients is essential.

Screening Perspectives: The Role of Colorectal Cancer Awareness in Shaping Attitudes Toward Colonoscopy in Palestine.

PURPOSE: To assess colorectal cancer (CRC) awareness and its influence on attitudes toward colonoscopy in Palestine. MATERIALS AND METHODS: Convenience sampling was used to recruit Palestinian adults from hospitals, primary health care centers, and public spaces across 11 governorates. To evaluate the awareness of CRC signs/symptoms, risk factors, and mythical causes, the Bowel Cancer Awareness Measure and Cancer Awareness Measure-Mythical Causes Scale were used after translation into Arabic. For each correctly recognized item, one point was given. The total awareness score of each domain was calculated and categorized into tertiles; the top tertile was considered high awareness, and the other two tertiles were considered low awareness. RESULTS: A total of 4,623 questionnaires were included. Only 1,849 participants (40.0%) exhibited high awareness of CRC signs/symptoms. High awareness of CRC symptoms was associated with higher likelihood of showing positive attitudes toward colonoscopy (odds ratio [OR], 1.21 [95% CI, 1.07 to 1.37]). A total of 1,840 participants (38.9%) demonstrated high awareness of CRC risk factors. Participants with high awareness of CRC risk factors were more likely to display positive attitudes toward colonoscopy (OR, 1.20 [95% CI, 1.07 to 1.37]). Only 219 participants (4.7%) demonstrated high awareness of CRC causation myths. There was no association between awareness of CRC causation myths and positive attitudes toward colonoscopy. CONCLUSION: Awareness of CRC was poor with less than half of the study participants demonstrating high awareness of CRC signs/symptoms and risk factors, and a minority (<5%) displaying high awareness of CRC causation myths. High awareness of CRC signs/symptoms and risk factors was associated with greater likelihood of demonstrating positive attitudes toward colonoscopy. Educational initiatives are needed to address knowledge gaps and dispel misconceptions surrounding CRC.

Differences in Colorectal Cancer Awareness Between Vegetarians and Nonvegetarians: A National Cross-Sectional Study From Palestine.

PURPOSE: To compare colorectal cancer (CRC) awareness between vegetarians and nonvegetarians in Palestine. MATERIALS AND METHODS: The validated Bowel Cancer Awareness Measure and Cancer Awareness Measure-Mythical Causes Scale were translated into Arabic and used to assess awareness of CRC signs/symptoms, risk factors, and mythical causes. The total awareness score of each domain was calculated and categorized into tertiles; the top tertile was considered as good awareness. Multivariable logistic regression analysis was used to examine the association between being a vegetarian and displaying good awareness in each domain. RESULTS: This study included 4,623 participants: 560 vegetarians (12.1%) and 4,063 nonvegetarians (87.9%). Lump in the abdomen was the most recognized CRC sign/symptom among both nonvegetarians (n = 2,969, 73.1%) and vegetarians (n = 452, 80.7%). Vegetarians were less likely than nonvegetarians to display good awareness of CRC signs/symptoms (odds ratio, 0.59 [95% CI, 0.48 to 0.72]). Lack of physical activity was the most identified modifiable CRC risk factor in both nonvegetarians (n = 3,368, 82.9%) and vegetarians (n = 478, 85.4%). Similarly, having a bowel disease was the most identified nonmodifiable risk factor among both nonvegetarians (n = 2,889, 71.1%) and vegetarians (n = 431, 77.0%). There were no associated differences between both groups in the awareness levels of CRC risk factors. The most recognized food-related CRC causation myth in nonvegetarians was drinking from plastic bottles (n = 1,023, 25.2%), whereas it was eating burnt food in vegetarians (n = 176, 31.4%). Having a physical trauma was the most recognized food-unrelated myth in both nonvegetarians (n = 2,356, 58.0%) and vegetarians (n = 396, 70.7%). There were no associated differences in the awareness of CRC causation myths between both groups. CONCLUSION: Awareness of CRC was notably low in both Palestinian vegetarians and nonvegetarians. Particularly, vegetarians demonstrated lower awareness of CRC signs and symptoms.

Amine-Based MOF for Precious Metal Remediation.

Due to the continuous growth rate of the electronic industry, hi-tech companies depend on mining and extracting precious metals to meet the public demand. The high turnover of modern devices generates an alarming amount of electronic waste (e-waste), which contains more precious metals than mined ores and therefore needs efficient recovery procedures. A highly stable homopiperazine-derived Cd-MOF, poly-[Cd(H2L)]·9H2O, with a protonated amine ligand core, exists as a twofold interpenetrated 3D framework with 1D channels into which the N+-H bond is directed. The geometry of these channels appears to be suitable to host square planar metalate complexes. Under acidic conditions, [MCl4]x- anions containing Au, Cu, Ni, and Pt, representing common components of e-waste under extraction conditions, were tested for capture and recovery. Cd-MOF exhibits remarkable selectivity and uptake performance toward Au with an adsorbent capacity of 25 mg g-1ads and shows a marked selectivity for Au over Cu in competitive experiments. The adsorption mechanism of Au appears to be predominantly physical adsorption at the surface of the material.

Comparison of the Colonic J-Pouch Versus Side-To-End Anastomosis Following Low Anterior Resection: A Systematic Review and Meta-Analysis.

BACKGROUND: The aim of this systematic review and meta-analysis is to evaluate clinical, functional, and anorectal physiology outcomes of the side-to-end vs colonic J-pouch (CJP) anastomosis following anterior resection for rectal cancer. METHODS: A PRISMA-compliant systematic review and meta-analysis was conducted using multiple electronic databases and clinical trial registers and all studies comparing side-to-end vs CJP anastomosis were included. Peri-operative complications, mortality rate, functional bowel, and anorectal outcomes were evaluated. RESULTS: Eight randomized controlled trials (RCTs) and two observational studies with 1125 patients (side-to-end: n = 557; CJP: n = 568) were included. Of the entire functional bowel outcome parameters analyzed, only the sensation of incomplete bowel evacuation was significant in the CJP group at 6 months [OR: 2.07; 95% CI 1.06 - 4.02, P = .03]. Peri- and post-operative clinical parameters were comparable in both groups (total operative time, intra-operative blood loss, anastomotic leak rate, return to theater, anastomotic stricture formation and mortality). Equally, most of the analyzed anorectal physiology parameters (anorectal volume, anal squeeze pressure, maximum anal volume) were not significantly different between the two groups. However, anal resting pressure (mmHg) 2 years post-operatively was noted to be significantly higher in the side-to-end group than that of the CJP configuration [MD: -8.76; 95% CI - 15.91 - 1.61, P = .02]. DISCUSSION: Clinical and functional outcomes following CJP surgery and side-to-end coloanal anastomosis are comparable. Neither technique appears to proffer solution to low anterior resection syndrome in the short term but future well-designed; high-quality RCTs with long term follow-up are required.

Protein supplement intake by non-athlete gym attendees in Jazan region: misconceptions and gender differences.

BACKGROUND: Protein supplements (PSs) have gained widespread popularity among non-athlete gym attendees, who often perceive them as essential tools for muscle growth and recovery. However, misinformation surrounding PSs may lead to inappropriate use and negative health consequences. This study aimed to assess whether non-athlete gym attendees using PSs have greater misconceptions than non-users while also examining the prevalence of PS consumption and gender differences. METHODS: A cross-sectional study of 387 participants in the Jazan region was conducted. Customers of 10 fitness centers were screened with a questionnaire comprising questions to measure PS misconceptions. Participants were divided into PS users and non-users. Data were analyzed using descriptive statistics and the Chi-square test to assess the associations between variables. An independent t-test was used to compare the PS Misconception Index Score between the two groups. RESULTS: A total of 82.4% of non-athlete gym attendees consumed at least one PS. Our findings revealed a significant association between gender and PS utilization (P<0.001), with a higher proportion of females (90.8%) consuming PS than males (77.6%). PS users had a significantly lower PS Misconception Index Score than non-users (26.8 vs. 28.3; P=0.006), indicating that PS users had a higher number of misconceptions. The internet (41.37%) and coaches (gym instructors/trainers) (34.48%) were the most common sources of information about PSs, with muscle gain being the primary reason for consumption (82.75%). CONCLUSIONS: PS consumption is highly prevalent among non-athlete gym attendees in the Jazan region, with many individuals having misconceptions about their benefits and potential risks. Targeted educational interventions are needed to promote evidence-based knowledge about PSs for gym attendees, as well as for coaches, given that they were among the primary sources of information on supplements.

Awareness, Knowledge, and Attitude Towards Urinary Tract Infections: An Appraisal From Saudi Arabia.

Introduction Urinary tract infections (UTIs) are a common global health issue, yet awareness and knowledge about UTIs among the general population can vary widely. This study aimed to assess the awareness, knowledge, and attitudes regarding UTIs among Saudi Arabian citizens residing in Al-Ahsa, Saudi Arabia. Methods A descriptive cross-sectional study was conducted among Saudi Arabian citizens aged 18 and above residing in Alhassa. A structured questionnaire was used to collect data on participants' awareness, knowledge, attitudes, and experiences related to UTIs. Data were analyzed using IBM® SPSS® Statistics. Results The study included 445 participants, predominantly males, with 279 (62.7%) and a range of educational backgrounds. Approximately 302 (70.1%) of the participants were aware of UTIs. However, misconceptions about the definition of UTI and its risk factors were common. Most participants recognized bacteria as the primary cause of UTIs, with 261 (58.7%) identifying this factor. Symptoms such as painful urination were recognized by 390 participants, which is a significant proportion. When experiencing UTI symptoms, 285 (66.1%) indicated they would go to the hospital. Significant associations were found between awareness, knowledge, and socio-demographic factors. Conclusion This study highlights the need for increased awareness and knowledge about UTIs among Saudi Arabian citizens in Alhassa. Tailored educational interventions are essential to correct misconceptions, promote accurate risk factor awareness, and encourage appropriate management strategies. Public health campaigns can contribute to reducing the burden of UTIs in the community.

Measurements of Groomed-Jet Substructure of Charm Jets Tagged by D

Understanding the role of parton mass and Casimir color factors in the quantum chromodynamics parton shower represents an important step in characterizing the emission properties of heavy quarks. Recent experimental advances in jet substructure techniques have provided the opportunity to isolate and characterize gluon emissions from heavy quarks. In this Letter, the first direct experimental constraint on the charm-quark splitting function is presented, obtained via the measurement of the groomed shared momentum fraction of the first splitting in charm jets, tagged by a reconstructed D^{0} meson. The measurement is made in proton-proton collisions at sqrt[s]=13 TeV, in the low jet transverse-momentum interval of 15≤p_{T}^{jet ch}<30 GeV/c where the emission properties are sensitive to parton mass effects. In addition, the opening angle of the first perturbative emission of the charm quark, as well as the number of perturbative emissions it undergoes, is reported. Comparisons to measurements of an inclusive-jet sample show a steeper splitting function for charm quarks compared with gluons and light quarks. Charm quarks also undergo fewer perturbative emissions in the parton shower, with a reduced probability of large-angle emissions.

Wireless pulmonary artery sensor implantation in a unilateral lung transplant recipient.

Patients with lung transplantation can have concomitant left ventricular failure which can either precede the lung transplantation or develop after. Implantable wireless pulmonary artery (PA) pressure monitors to guide hemodynamic management in heart failure such as the CardioMEMS device (Abbott, Sylmar, CA, USA) have been shown to improve outcomes. However, in a lung transplant recipient there are unique physiological and practical considerations when contemplating to implant a PA pressure sensor such as safety of implanting the device, choice of site of implantation, accuracy of wedge tracings to calibrate, and exclusion of vascular stenoses post transplantation. We discuss these considerations in the context of a man in his early 60s with a known left lung transplant two years previously who developed worsening heart failure needing invasive monitoring. Right lung PA sensor placement was considered, but on selective pulmonary angiography the right PA was found to be of small caliber and with significant tortuosity. After careful hemodynamic assessment, the PA sensor was implanted in the PA of the transplanted lung which is the first such case to our knowledge. Learning objective: We report the first documented case of an implantable wireless pulmonary artery pressure monitor (CardioMEMs) into a transplanted lung. Device-related complications, such as pulmonary artery injury, infection, and hemoptysis, must be assessed after placement. Given the changes in pulmonary artery pressures after lung transplantation, recalibration of the CardioMEMs device may need to be considered if placed within first year of transplant.

Background: Medical education is known to be stressful and demanding. Medical students face a various stressors, which include academic pressure, fear of not reaching goals, and difficulty integrating into systems. This study aims to assess levels of stress and coping strategies among medical students at Jazan University in Saudia Arabia. Materials and Methods: A descriptive cross-sectional study was conducted that comprised of 240 students at Jazan Faculty of Medicine using a self-administrated questionnaire to obtain data on socio-demographic characteristics, perceived stress, stressors, and coping strategies. Results: Respondents mean age was 22.08 ± 1.82 years and 52.7% were female. Of these, 51.9% were in preclinical years of study, 29.5% were in the second academic year, and 39.8% had a GPA greater than 4. Students stress level ranges from moderate to high. The most common causes were academic problems and frequency of examinations and work overload (92.1%), worrying about the future (61.8%), and lack of entertainment and time for recreation (58.9%). The most common coping strategy was recreational activity such as going to movies, watching TV, reading, sleeping, or shopping (36.5%). Mean perceived stress scale (PSS) and Brief-COPE scores were 24.1 ± 4.85 and 66.16 ± 10.71, respectively. Participant age and PSS score have significant positive correlation (P < 0.05). Conclusion: Stress level is moderate to high especially among students in preclinical years and among females. It is recommended to improve teaching and learning environment plus proper counseling and academic support. Also, active involvement of students in the educational process may help reduce academic stressors. Plain Language Summery: Medical students face a range of stressors due to the demands of study.
