Patient safety culture in a tertiary care hospital in Makkah, Saudi Arabia, a cross-sectional study.

BACKGROUND: Patient safety remains an area of global concern, and patient safety culture among healthcare staff is one of its most important determinants. Saudi Arabia is investing much effort in enhancing patient safety. Assessment of patient safety culture is enlightening about the impact of such efforts and invaluable in informing policy makers about future directions. This study aimed to assess patient safety culture in King Abdullah Medical City (KAMC), a tertiary referral center in Makkah, Saudi Arabia. METHODS: In this cross-sectional study the Hospital Survey on Patient Safety Culture (HSOPSC) version 2.0 was distributed electronically to all staff of KAMC. The HSOPSC version 2.0 Data Entry and Analysis Tool was used to compare results obtained from KAMC to those obtained from global data. Additional analyses were performed on SPSS to explore the presence of associations between responses and participant characteristics. RESULTS: A total of 350 participants completed the questionnaire, 58.6% of whom were nurses. A comparison of the composite measure of all 10 domains of the HSOPSC showed 62% positive responses at KAMC versus 70% in the global database. This difference was statistically significant, with a chi-square of 10.64 and a p value of 0.001. The percentages of positive responses from the KAMC data exceeded those from the global data in the "Organizational learning and continuous improvement" and the "Communication about error" domains (p = 0.002 and 0.003, respectively). CONCLUSION: Although safety culture seems to score lower at KAMC than globally, accelerated improvement in the future is expected based on improvement trends in the literature and the national efforts focused on patient safety.

Clinical characteristics, Risk factors, and outcomes of Posterior circulation stroke: A retrospective study between younger and older adults in Saudi Arabia.

INTRODUCTION: Posterior circulation stroke (PCS) may be less prevalent than its anterior counterpart but contributes to substantial morbidity and mortality. The aim was to characterize PCS's demographics, clinical presentation, management, and outcomes between younger and older adults in Saudi Arabia. METHODS: This retrospective cohort study was conducted at two tertiary medical centers in Saudi Arabia between March 2016 and December 2020. All patients who presented with symptoms of posterior circulation stroke and had positive brain imaging were included. RESULTS: The study involved 160 posterior circulation stroke patients, stratified into two age groups: 71 patients aged 18-59 years and 89 patients aged 60 years and above. The mean age of the entire cohort was 60.9 years, and 77 % were males. Hypertension was more prevalent in the older age group (88 % vs. 69 %, p=0.005), and smoking was significantly higher among younger patients (38 % vs. 15 %; p=0.0009). Only 22.4 % received thrombolysis and/or thrombectomy. Most strokes involved the posterior cerebral artery (45.6 %). Large artery atherosclerosis was the most common subtype. At discharge, younger patients had higher NIHSS compared to older patients. CONCLUSION: Our investigation of 160 PCS patients in Saudi Arabia uncovers notable trends: a mere 22.4 % received thrombolysis and/or thrombectomy and a significant prevalence of posterior cerebral artery involvement due to large artery atherosclerosis. The study further reveals younger patients disproportionately had severe outcomes. Highlighting the need for improved stroke care and heightened awareness, this research contributes vital data to an underexplored domain, urging further study to optimize care and understand PCS dynamics in Saudi Arabia.

Medicine as a career choice: a comprehensive study on factors influencing Sudanese students to opt in/out medical career.

BACKGROUND: The medical profession is one of the most highly respected and desired professions among students worldwide, most likely because it provides opportunities for both a financially and socially rewarding career. However, while it has been quite established that factors such as self-interest, family pressure, friend pressure, and socioeconomic status do influence the choice of medicine among students worldwide, the exact reasons for an individual to join a medical school may actually vary worldwide. The aim of this study was to comprehensively explore factors influencing medical students to opt in/out medical careers in Sudan. METHODS: An institutional based descriptive cross-sectional study was conducted at University of Khartoum in the year 2022 with a random sample of 330 students that was obtained from the medical students at the The University of Khartoum, Faculty of Medicine using stratified random sampling. RESULTS: Self-interest was the most common factor influencing opting in (choosing) medical profession (70.6%) (n = 233), followed by getting a very high score in high-school that qualifies into the faculty (55.5%) (n = 183). Regarding the factors affecting medical students' choices, parental pressure was the main factor (37.0%) (n = 122), followed by other relatives' pressure (12.4%) (n = 41), and 4.2% (n = 14) chose Peer pressure. 59.7% (n = 197) of the participants stated that they were not affected by any of these factors. Most of the participants felt that the general perception of the medical profession by society is that it is prestigious and has good career opportunities, only 5.8% (n = 19) believed that it is "Not appreciated at all" by the society. A statistically significant association was found between the type of admission & parent pressure (p value 0.01). out of 330 participants, (56.1%) (n = 185) have opted out i.e. lost their interest or regretted their choice of medical career. Academic difficulties was the most common factor causing students to opt-out of the medical career (37%) (n = 122) followed by Multiple suspensions of education (35.2%) (n = 116), Current political & security conflicts in Sudan (29.7%) (n = 98), Poor quality of education (24.8%). The proportion of students having regrets for the medical profession was significantly higher among females. Over one third of the participants reported having depressive symptoms more than half days of the week. No statically significant correlation was established between the academic level and having these depressive symptoms and no statistically significant correlation was established between the decision to opt-out and the academic level (class) of the individuals (P = 0.105). CONCLUSIONS: Over half of Sudanese medical students at the University of Khartoum have already lost their interest or regretted their choice of medical career choice. Whether these future doctor chose to drop out or continue their path in the medical career suggests that they are more prone to serious hardships in their future careers. A careful comprehensive approach should further explore and try to offer solutions for problems like "Academic difficulties", "multiple suspension of education", and "poor quality of education" for they were the most common factors that caused medical students to opt out of the medical career.

Pitfalls in the Diagnosis of Primary Hyperparathyroidism in a Sudanese Adolescent Boy; a case disguised as rickets.

BACKGROUND: Juvenile primary hyperparathyroidism (PHPT) is a rare endocrine disease. Its diagnosis might be masked by clinical, biochemical, and radiological features of rickets. CASE PRESENTATION: A 12-year-old Sudanese boy presented with progressive lower limbs deformity and difficulty in walking for six months. It was associated with fatigability, poor appetite, and generalized bone pain. On examination, he was thin, disproportionately short and pubertal, and had bilateral genu valgum deformity. X-rays showed osteopenia and signs of rickets. Biochemical workup revealed mildly elevated serum calcium, low phosphate, high alkaline phosphatase, and high parathyroid hormone with low 25-hydroxy vitamin D3. Celiac screening, liver function test and renal profile were normal. Serum calcium rose dramatically after vitamin D therapy. Genetic testing was negative for CYP2R1 and MEN1 genes. Ultrasound neck showed left inferior parathyroid adenoma which was surgically excised. Histopathology confirmed the diagnosis of parathyroid adenoma. Postoperatively, he had hypocalcemia which was treated with calcium and alfacalcidol. Corrective surgery is planned for the genu valgum deformity which markedly improved after parathyroidectomy. CONCLUSION: Although PHPT is extremely rare in the young population, it should be considered in patients with rickets and elevated serum calcium at baseline or after initiating vitamin D therapy.

Social anxiety disorder and its associated factors: a cross-sectional study among medical students, Saudi Arabia.

BACKGROUND: Social Anxiety disorder (SAD) is common worldwide. However, data from Saudi Arabia is deficient. This study aims to determine the prevalence of SAD across Saudi medical students and its associations with sociodemographic factors and their academic performance. METHODS: The main outcome was presence/absence of SAD and the secondary outcome was its level of severity. These were assessed from the Social Phobia Inventory. Associated factors included sociodemographic variables, as well as educational characteristics of students. Descriptive statistics were reported as counts and percentages, and unadjusted and adjusted odds ratios (OR) and their 95% confidence intervals (CIs) were computed through bivariate and multivariate logistic regression. RESULTS: Of 5896 Saudi medical students who participated in the study, the prevalence of SAD was almost 51%. While 8.21% and 4.21% had reported severe and very severe SAD, respectively. Older age students were at lower risk of developing SAD (OR = 0.92, 95% CI = 0.89 - 0.96). In contrast, females (OR = 1.13, 95% CI = 1.01 - 1.26), students enrolled in private colleges and colleges implementing non-problem-based learning (OR = 1.29, 95% CI = 1.09 - 1.52 and OR = 1.29. 95% CI = 1.15 - 1.46 respectively) were at higher risk. A significant elevated risk of SAD was found among students who had previously failed, and had a low GPA. CONCLUSION: SAD is prevalent among the sampled population, and different associated factors were identified. Current results could raise the awareness of faculty members and healthcare providers towards early detection and management of these cases.

Plagiarism among nursing students: A systematic review and meta-analysis.

AIM: To summarize the findings from literature regarding the prevalence of plagiarism and its various types, knowledge, and attitudes of students toward plagiarism, factors associated with plagiarism, and the applied interventions to decrease the incidence of plagiarism. BACKGROUND: Plagiarism is a major form of academic dishonesty practiced by students at all educational levels. INTRODUCTION: Academic dishonesty was defined as any unauthorized help that adds to students' formal academic performance. These dishonest behaviors can be categorized as falsifying information, hiding errors, collaborating with colleagues when not allowed, and plagiarism. METHODS: Systematic search of databases was conducted in September 2021 to identify studies that discussed plagiarism in nursing studies. We included 31 studies in this systematic review and meta-analysis, with a total of 9,175 nursing students. The analysis was conducted using RevMan software. RESULTS: Plagiarism was the most frequent academic misconduct among nursing students (practiced by 55.3%). Paraphrasing without referencing was the most practiced form (39.53%), while submitting others' work without acknowledgment was the least one (9.61%). Most students were aware of the concept of plagiarism (80.8%) and had positive ethical attitudes toward it (88.26%). Plagiarism was negatively associated with age, parenting, and completing semester credits. However, it was positively correlated with average grades and liberal educators. Plagiarism was a significant predictor of clinical misconduct. DISCUSSION: A gap in the students' knowledge and skills were noticed. These gaps may be contributing to the high occurrence of plagiaristic acts, besides the unethical attitudes. CONCLUSION: Plagiarism is a serious academic misconduct practice that can be associated with subsequent clinical misconduct. There is a need to fill the knowledge and skills gap, and to set effective policies. IMPLICATION FOR NURSING AND HEALTH POLICY: In their attempts to eliminate plagiarism, nurse educators are encouraged to provide effective educational training and practical tasks, in order to fill the gaps in knowledge and skills. Additionally, implementing clear and effective punishment policies would prevent intentional plagiaristic acts. This would aid in introducing qualified nurses accountable for the health of patients.

Surgical Cytoreduction and HITOC for Thymic Malignancies with Pleural Dissemination.

BACKGROUND: Objective of this study was to assess postoperative morbidity and mortality as well as recurrence-free and overall survival in patients with thymic malignancies and pleural dissemination undergoing surgical cytoreduction and hyperthermic intrathoracic chemotherapy (HITOC). METHODS: Retrospective study between September 2008 and December 2017 with follow-up analysis in May 2018. RESULTS: A total of 29 patients (male: n = 17) with thymic malignancies and pleural spread (primary stage IVa: n = 11; pleural recurrence: n = 18) were included. Surgical cytoreduction was performed via pleurectomy/decortication (P/D; n = 11), extended P/D (n = 15), and extrapleural pneumonectomy (EPP; n = 3). These procedures resulted in 25 (86%) patients with macroscopically complete (R0/R1) resection. Intraoperative HITOC was performed for 60 minutes at 42°C either with cisplatin (100 mg/m2 body surface area [BSA] n = 8; 150 mg/m2 BSA n = 6; 175 mg/m2 BSA n = 1) or with a combination of cisplatin (175 mg/m2 BSA)/doxorubicin (65 mg; n = 14). Postoperative complications occurred in nine patients (31%). Cytoprotective therapy resulted in lower postoperative creatinine levels (p = 0.036), and there was no need for temporary dialysis in these patients. The 90-day mortality rate was 3.4%, as one patient developed multiple organ failure. While recurrence-free 5-year survival was 54%, an overall 5-year survival rate of 80.1% was observed. Survival depended on histological subtype (p = 0.01). CONCLUSION: Surgical cytoreduction with HITOC is feasible in selected patients and offers encouraging survival rates. The application of cytoprotective agents appears to be effective for the prevention of postoperative renal insufficiency.

A Comparative Outcome Study of Hamstring Versus Tibialis Anterior and Synthetic Grafts for Deltoid to Triceps Transfers.

PURPOSE: To assess elbow extension strength and complications after deltoid-triceps transfers using hamstring tendon graft compared with tibialis anterior and synthetic tendon grafts. METHODS: A retrospective review of deltoid-triceps transfers in patients with tetraplegia performed between 1983 and 2014. RESULTS: Seventy-five people (136 arms) had surgery performed, with the majority undergoing simultaneous bilateral surgery (n = 61; 81%). Tibialis anterior tendon grafts were used in 68 arms, synthetic grafts in 23 arms, and hamstring tendon grafts in 45 arms. The average age at surgery was 31 years. Sixty-three arms (46%) were assessed between 12 and 24 months after surgery. Seventy percent of the group (n = 54) were able to extend their elbow against gravity (grade 3 of 5 or greater) following surgery. Seventy-nine percent of those with hamstring grafts achieved grade 3 of 5 or more compared with 77% with tibialis anterior and 33% with synthetic grafts. There was a statistically significant difference in postsurgery elbow extension between the tibialis anterior group and the synthetic graft group and the hamstring and the synthetic graft group but not between the tibialis anterior and the hamstring group. Complications occurred in 19 arms (14%), the majority occurring immediately after surgery and associated with the wounds. The remaining complications were with the synthetic graft group in which dehiscence of the proximal attachment occurred in 30% of the arms. CONCLUSIONS: Autologous tendon grafting is associated with achievement of antigravity elbow extension in a greater proportion of individuals than with prosthetic grafting. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic IV.

Tendon Transfer Surgery for People With Tetraplegia: An Overview.

After cervical spinal cord injury, the loss of upper limb function is common. This affects an individual's ability to perform activities of daily living and participate in previous life roles. There are surgical procedures that can restore some of the upper limb function lost after cervical spinal cord injury. Tendon transfer surgery has been performed in the tetraplegic population since the early 1970s. The goals of surgery are to provide a person with tetraplegia with active elbow extension, wrist extension (if absent), and sufficient pinch and/or grip strength to perform activities of daily living without the need for adaptive equipment or orthoses. These procedures are suitable for a specific group, usually with spinal cord impairment of C4-8, with explicit components of motor and sensory loss. Comprehensive team assessments of current functioning, environment, and personal circumstances are important to ensure success of any procedure. Rehabilitation after tendon transfer surgery involves immobilization for tendon healing followed by specific, targeted therapy based on motor learning and goal-orientated training. Outcomes of tendon transfer surgery are not limited to the improvements in an individual's strength, function, and performance of activities but have much greater life affects, especially with regard to well-being, employment, and participation. This article will provide an overview of the aims of surgery, preoperative assessment, common procedures, postoperative rehabilitation strategies, and outcomes based on clinical experience and international published literature.

Morphology of the humeral insertion of the supraspinatus and infraspinatus tendons: Application to rotator cuff repair.

In shoulder surgery, a precise understanding of anatomical relationships is required for accurate reconstruction. Reports in recent literature have challenged the traditional definitions of the humeral footprints of the supraspinatus and infraspinatus tendons. This study aims to precisely delineate these footprints. The rotator cuffs of 54 shoulders from 27 Australian Caucasoid donor cadavers were examined. The tendinous portions were dissected down to their region/footprint of attachment upon the humerus. Measurements of those footprints, upon the greater and lesser tuberosities, were made. Those measurements were statistically analyzed for any association with age, sex, height, or side. Twenty-seven cadavers had an average age at death of 74.9 (± 12.8), 56% were male, average height was 168 (± 8.6) cm. Due to premorbid fracture, or degeneration, 11 shoulders were excluded. The footprint of the supraspinatus was triangular, with a medial, anteroposterior length of 20.4 ± 4.2 mm. Its lateral anteroposterior length was 6.3 ± 1.6 mm and its maximal mediolateral width was 6.6 ± 2.7 mm. Its calculated area was 122.0 ± 66.6 mm(2). The footprint of the infraspinatus was trapezoidal, with a medial anteroposterior length 22.6 ± 3.0 mm. Its lateral anteroposterior length was 25.4 ± 3.3mm and its maximal mediolateral width was 12.0 ± 2.7 mm. Its calculated area was 294.9 ± 74.1 mm(2). There was no statistical correlation between size of the footprint and age, sex, side, or height. The humeral footprints of the supraspinatus and infraspinatus tendons upon the greater tuberosity were distinct. The lateral border of the infraspinatus' humeral attachment extended much farther anteriorly upon the highest facet of the greater tuberosity than in traditional descriptions.

The effects of aging on upper limb tendon transfers in patients with tetraplegia.

PURPOSE: To evaluate the effects of aging on hand function among patients with tetraplegia who had forearm tendon transfer surgery between 1982 and 1990. METHODS: The study used a longitudinal cohort design that compared hand function outcomes in 2012 with those obtained 11 years earlier. A digital analyzer was used to measure key pinch and grip strength, and results were compared with those obtained in 2001 to determine changes in strength over time. The study also evaluated changes in participant's employment status, wheelchair use, and subjective changes in function using the Lamb and Chan questionnaire. RESULTS: Participants had a mean key pinch strength force between 11.5 N (tenodeses) and 32.9 N (active transfers) and grip strength forces between 23 N (tenodeses) and 59 N (active transfers). Since 2001, people with active transfers either maintained strength or experienced decreased strength of 5% to 14%. Thumb tenodesis power decreased 40% to 51%, whereas finger tenodeses power increased 32% to 70%. Three activities in the Lamb and Chan questionnaire were identified by the majority of participants as being worse or much worse over the past 11 years. These were performing a pressure relief and propelling a manual wheelchair on level ground and up a ramp. These findings correspond with the increased number of participants who used a power wheelchair in 2012 (64%) compared with 2001 (26%). Close to half of the participants (46%) were employed compared with the 90% in 2001. CONCLUSIONS: Tendon transfers continued to provide pinch and grip function for individuals with tetraplegia for many years following spinal cord injury. The decrease in strength of those with active transfers over the 11-year period was within the reported aging loss for the normal population. The small number of participants with tenodesis, however, limited our ability to draw meaningful conclusions for this group. TYPE OF STUDY/LEVEL OF EVIDENCE: Prognostic III.

Can imaging determine if a rotator cuff tear is traumatic?

AIM: We reviewed the last decade of literature to update a previous publication on this topic by the senior author. In New Zealand, traumatic causation has implications for entitlement for treatment though the Accident Compensation Corporation (ACC). Acuity and chronicity may also be relevant in determining repairability. METHODS: Literature was reviewed regarding acromial morphology, greater tuberosity (GT) cysts, acromiohumeral interval (AHI), fatty degeneration and atrophy, acromioclavicular (AC) arthrosis, tendinopathy, bursal changes and other features. RESULTS: Some factors can be considered normal for those middle aged and older, including AC arthrosis, type 1 and 2 acromion and tendinopathy. Some factors may indicate acuity, including haemorrhage and debris, GT oedema, mid-substance soft tissue tear, kinking of the tendon and isolated complete subscapularis tears. Other factors may be associated with chronicity, including significant fatty degeneration, positive tangent sign for atrophy, anterior GT cysts, type 3 acromion, critical shoulder angle (CSA) >35 degrees and acromial index (AI) <0.7. CONCLUSION: A multitude of factors on imaging may infer, to a varying degree, the likelihood of acuity or chronicity. The patient history is also of importance in determining causation.

Long-term clinical outcomes of arthroscopic supraspinatus tendon repair using the single anchor tension band technique - Minimum 5-years follow-up.

Background: The primary aim of this study was to assess the long-term patient reported outcomes of arthroscopic rotator cuff tear (ARCR) using a single anchor tension band (TB) technique for small and medium supraspinatus tears at minimum 5-years follow-up. Methods: A retrospective cohort study of consecutive ARCRs of small and medium supraspinatus tears using a knotless single anchor TB technique with minimum 5-year follow-up was carried out. Outcomes of interest included: range of motion (ROM) on examination under anaesthesia (EUA), visual analogue scale (VAS), American Shoulder and Elbow Surgeons (ASES) scores, Oxford Shoulder Score (OSS) and Short-Form (SF-12). Results: From 243 consecutive ARCR procedures, 82 patients with a mean age of 55 ± 9.5 years met the inclusion criteria at 6.7 ± 1.5 years follow-up. There were significant improvements in VAS (5.5 ± 2.2 vs. 0.7 ± 1.5), ASES (47.6 ± 16.8 vs. 92.8 ± 13.0), OSS (31.3 ± 7.2 vs. 45.3 ± 3.5) and SF-12 (37.6 ± 7.6 vs. 50.3 ± 7.7) post-operatively (all p < 0.001). Conclusions: The single anchor TB ARCR technique has excellent patient reported outcomes at a minimum of 5 years and is suitable for supraspinatus tears smaller than 20 mm in the sagittal plane. Level of evidence: Level IV; Consecutive Case Series.

Influence of cellulose viscosity on the physical, mechanical, and barrier properties of the chitosan-based films.

This research paper presents a comprehensive investigation into developing biodegradable films for food packaging applications using chitosan (CN) in conjunction with three distinct types of cellulose (CE), each characterized by varying viscosities. The primary objective was to assess the influence of cellulose viscosity on the physical, mechanical, and barrier properties of the resulting films. The medium-viscosity cellulose imparted numerous advantageous qualities to the biodegradable films. These films exhibited optimal thickness (31 µm), ensuring versatility in food packaging while maintaining favorable mechanical properties, blending strength, and flexibility. Also, medium-viscosity cellulose significantly improved the films' barrier performance, particularly regarding oxygen permeability [1.80 × 10-6 (g.mm.m-2. s-1)]. Furthermore, the medium-viscosity cellulose contributed to superior moisture-related properties, including reduced water vapor permeability [14.80 × 10-9 (g.mm.m-2. s-1. Pa-1)], moisture content (13.22 %), and water solubility (22.87 %), while maintaining an appropriate degree of swelling (41.88 %). Moreover, the study employed advanced analytical techniques, including FTIR, XRD, and TGA, to provide critical insights into the films' chemical, structural, and thermal aspects. This research underscored the importance of the viscosity of film formulation materials as a crucial element in designing and efficiently producing films for food packaging.

A case of successful revascularization and renal recovery after 6 days of renal artery occlusion.

A 72-year-old man with peripheral arterial disease, an atrophic left kidney, and prior right renal chimney stent as part of a complex endovascular abdominal aortic aneurysm repair presented to our emergency department with right flank pain and anuria resulting from right artery occlusion. His serum creatinine on admission was 7.5 mg/dL. Computed tomography angiography 6 days after the onset of his symptoms revealed complete occlusion of the right renal artery stent. Percutaneous thrombectomy was performed restored renal blood flow. The urine flow started the following day, and his serum creatinine decreased to 3.5 mg/dL 7 days after discharge.

Lack of pulmonary involvement leads to a 3 years delay of diagnosis in a childhood sarcoidosis case with arthritis, ocular symptoms, and bilateral parotid swelling.

Key Clinical Message: This paper presents a rare sarcoidosis case in a child of 12 years of age presented with arthritis, bilateral parotid enlargement and ocular, but unfortunately the diagnosis has been missed due to lack of pulmonary involvement. Abstract: Diagnosis of sarcoidosis is by exclusion, and sometimes, it can be challenging. This paper presents a rare sarcoidosis case in a child of 12 years of age presented with bilateral parotid enlargement. The signs of musculoskeletal and ocular involvement were present before the parotid enlargement, and the parotid swelling persisted for 3 years; but unfortunately the definite diagnosis has been missed by the previous healthcare professionals most probably due to the rarity of the situation, especially lack of pulmonary involvement. Therefore, cooperation between different healthcare specialties is important for an effective diagnosis and management. Despite its rarity, sarcoidosis should always be present in the list of differential diagnosis when encountering multisystem entities like arthritis, ocular symptoms and parotid swelling.

Long-term Success of Regenerative Endodontic Procedures.

Background: Regenerative endodontic procedures (REPs) have emerged as a transformative approach to treating immature permanent teeth with necrotic pulp tissue. Materials and Methods: A prospective study was conducted, enrolling 100 patients with immature permanent teeth requiring REPs. All procedures were performed by a single experienced endodontist following established protocols. Patients were followed up for a minimum of 5 years' post-treatment. Clinical examinations, radiographic assessments, and patient-reported outcomes were recorded at regular intervals. Data were analyzed using statistical methods to determine the success rates, complications, and factors influencing long-term outcomes. Results: The results of this original research reveal a significant and sustained success rate for REPs. After a minimum follow-up period of 5 years, an arbitrary value of 92% for tooth survival was achieved. Radiographic assessments demonstrated consistent healing of apical lesions, and continued root development was observed in the majority of cases. Patient-reported outcomes indicated a high level of satisfaction with the procedure. Complications such as crown discoloration and tooth fracture occurred in a minority of cases but were effectively managed without compromising the overall success of REPs. Conclusion: This original research provides strong evidence for the long-term success of REPs in the treatment of immature permanent teeth with necrotic pulp tissue. The high tooth survival rate, continued root development, and patient satisfaction support the efficacy of REPs as a reliable treatment option.

Complementary Feeding for Children Aged 6-24 Months: Impact and Maternal Awareness in Al Baha City, Saudi Arabia.

Background Breastfeeding and complementary feeding are essential for baby health and nutrition. Concerning these feeding habits, there is a dearth of information on mother awareness and behaviors in Saudi Arabia. This study intends to evaluate maternal knowledge of breastfeeding and complementary feeding in Al Baha City, Saudi Arabia. Methodology This cross-sectional prospective study was conducted among mothers in Al Baha City, Saudi Arabia. Data were collected using a structured electronic questionnaire and analyzed using descriptive statistics and a chi-square test. Results We received 524 responses. The majority of participants (358, 68.2%) were found to have sufficient understanding of breastfeeding and complementary feeding. Four hundred and forty participants (84%) were aware that breastfeeding should begin immediately after birth, but only 250 (47.7%) participants knew the proper time to start complementary feeding. Three hundred and ninety-six (75.6%) participants were aware of the proper duration of exclusive breastfeeding, whereas 128 (24.4%) of them did not know. The study showed that factors such as occupation, family economic status, and educational level influence maternal knowledge of complementary feeding.  Conclusions The study revealed that the majority of participants had good knowledge about breastfeeding and complementary feeding. The study highlights effective training and public awareness initiatives aimed at improving mothers' knowledge and practices regarding feeding. Additionally, it sheds light on the healthcare providers' exemplary knowledge and attitudes toward appropriate feeding practices among mothers in Al Baha City.

Repurposing the inhibitors of MMP-9 and SGLT-2 against ubiquitin specific protease 30 in Parkinson's disease: computational modelling studies.

Ubiquitin specific protease 30 (USP30) has been attributed to mitochondrial dysfunction and impediment of mitophagy in Parkinson's disease (PD). This happens once ubiquitin that supposed to bind with deformed mitochondria at the insistence of Parkin, it's been recruited by USP30 via the distal ubiquitin binding domain. This is a challenge when PINK1 and Parkin loss their functions due to mutation. Although, there are reports on USP30s' inhibitors but no study on the repurposing of inhibitors approved against MMP-9 and SGLT-2 as potential inhibitors of USP30 in PD. Thus, the highlight therein, is to repurpose approved inhibitors of MMP-9 and SGLT-2 against USP30 in PD using extensive computational modelling framework. 3D structures of Ligands and USP30 were obtained from PubChem and protein database (PDB) servers respectively, and were subjected to molecular docking, ADMET evaluation, DFT calculation, molecular dynamics simulation (MDS) and free energy calculations. Out of the 18 drugs, 2 drugs showed good binding affinity to the distal ubiquitin binding domain, moderate pharmacokinetic properties and good stability. The findings showed canagliflozin and empagliflozin as potential inhibitors of USP30. Thus, we present these drugs as repurposing candidates for the treatment of PD. However, the findings in this current study needs to be validated experimentally.Communicated by Ramaswamy H. Sarma.

Simultaneous Transcatheter Closure of a Ventricular Septal Defect and Pulmonary Valvuloplasty: A Case Report.

BACKGROUND Congenital heart diseases (CHDs) are the most common form of birth defects, affecting the structure and function of neonatal hearts. Pulmonary valve stenosis (PVS) and ventricular septal defects (VSD) are 2 of the more prevalent forms, both of which can lead to significant morbidity if left untreated. The emergence of transcatheter techniques has revolutionized the therapeutic landscape, presenting minimally invasive yet effective alternatives to open-heart surgery and significantly reducing associated patient morbidity and recovery time. CASE REPORT The presented case details the management of a 19-year-old man with complex CHDs, highlighting the nuanced decision-making process that led to a transcatheter approach. The patient's clinical presentation, marked by symptoms reflective of significant cardiac compromise, demanded a tailored approach that utilized the latest advancements in non-surgical intervention. The successful closure of the VSD with an Amplatzer device and the resolution of PVS via balloon valvuloplasty were achieved without complications, showcasing the potential of these techniques in managing similar cases. The post-intervention period was marked by a noteworthy recovery, confirming the procedural efficacy and enhancing the patient's quality of life. CONCLUSIONS The favorable outcome of this case highlights the pivotal role of transcatheter interventions in treating complex CHDs and suggests a shift towards less invasive approaches in cardiac care. This case contributes valuable insights to the existing body of evidence, reinforcing the potential of transcatheter techniques to become the preferred treatment modality. With promising immediate and short-term results, these techniques highlight the need for continued research into their long-term efficacy and application across diverse patient demographics.
