Introduction: To date, there is no comprehensive systematic review and meta-analysis to assess the suitability of COVID-19 vaccines for mass immunization. The current systematic review and meta-analysis was conducted to evaluate the safety and immunogenicity of novel COVID-19 vaccine candidates under clinical trial evaluation and present a contemporary update on the development and implementation of a potential vaccines. Methods: For this study PubMed, MEDLINE, and Embase electronic databases were used to search for eligible studies on the interface between novel coronavirus and vaccine design until December 31, 2020. Results: We have included fourteen non-randomized and randomized controlled phase I-III trials. Implementation of a universal vaccination program with proven safety and efficacy through robust clinical evaluation is the long-term goal for preventing COVID-19. The immunization program must be cost-effective for mass production and accessibility. Despite pioneering techniques for the fast-track development of the vaccine in the current global emergency, mass production and availability of an effective COVID-19 vaccine could take some more time. Conclusions: Our findings invited a revisit to the reported solicited and unsolicited SAE for COVID-19 candidate vaccines. Hence, it is alarming to judiciously expose thousands of participants to COVID-19 candidate vaccines at Phase-3 trials that have adverse events and insufficient evidence on safety and effectiveness that necessitates further justification.

Background: The novel coronavirus disease 2019 (COVID-19) outbreak, caused by the pathogenic severe acute respiratory syndrome-2 (SARS-CoV-2) virus, is exponentially spreading across the globe. Methods: The current systematic review was performed utilizing electronic databases i.e. PubMed, MEDLINE and EMBASE. We searched for the keywords "COVID-19 AND "pregnancy" between January 1st, 2020 until December 31, 2020. Results: Out of 4005 records which were identified, 36 original studies were included in this systematic review. Pooled prevalence of vertical transmission was 10%, 95% CI: 4-17%. Pooled prevalence of neonatal mortality was 7%, 95% CI: 0-21%. Conclusion: The contemporary evidence suggests that the incubation period of COVID-19 is 2-14 days, and this infection could be transmitted even from the infected asymptomatic individuals. It is found that the clinical presentation of pregnant women with COVID-19 infection is comparable with the infected non-pregnant females, and the frequent symptoms were fever, cough, myalgia, sore throat and malaise. There are some cases with severe maternal morbidity and perinatal deaths secondary to COVID-19 infection. Under these circumstances, the pregnant women should focus on maintaining personal hygiene, proper nutrition and extreme social distancing to reduce the risk of COVID-19. Therefore, a systematic data reporting for evidence base clinical assessment, management and pregnancy outcomes is essential for prevention of COVID-19 infection among pregnant women.

Purpose: To investigate the outcomes of premature neonates with short bowel syndrome (SBS) managed under a BEAR (Bowel Elongation and Advanced Rehabilitation) protocol. Methods: This was a retrospective cohort study of preterm patients with SBS, treated at Sidra Medicine between January 2018 and February 2024. Data were extracted from electronic medical records, including patient demographics, clinical history, surgical interventions, parenteral nutrition (PN) duration, and long-term outcomes. The BEAR protocol incorporated a multidisciplinary approach with structured intestinal rehabilitation, hepato-protective PN strategies, and staged surgical interventions to promote enteral autonomy. Results: A total of 20 premature neonates with SBS were analyzed, with a median gestational age of 28 weeks and a median birth weight of 860g. Necrotizing enterocolitis was the primary cause of SBS in 90% of cases. Of the cohort, 80% successfully weaned off PN, achieving enteral autonomy at a median corrected age of 19.7 months. Seven patients underwent serial transverse enteroplasty (STEP), with 6/7 successfully transitioning to full enteral feeding. The study demonstrated favorable survival rates and reduced PN-associated complications. Conclusion: The BEAR protocol provides a structured and effective approach to intestinal rehabilitation in premature neonates with SBS, facilitating early enteral autonomy and minimizing long-term PN dependence. These findings contribute valuable clinical insights into optimizing multidisciplinary management strategies for this high-risk population.

Background/Objectives: Hypospadias, a common congenital anomaly in males, presents significant challenges in diagnosis, management, and long-term care. Despite its prevalence, research into the condition has been hampered by the lack of integrated biobank cohorts linking clinical, phenotypic, and surgical data with biological samples. This study aimed to establish the Hypospadias Biobank Cohort (HBC), a comprehensive resource designed to advance the understanding of hypospadias etiology and improve patient outcomes. Methods: The HBC was developed using a multi-phase approach, enrolling participants from specialized clinics between April 2022 and September 2024. Biological samples (blood and tissue) were collected under standardized protocols following informed consent. Detailed clinical data, including hypospadias severity, associated anomalies, and surgical outcomes, were systematically recorded and integrated into a robust database to support translational research. Results: The cohort included a diverse group of patients with varying severity of hypospadias, many of whom also presented with associated anomalies. Surgical outcomes were tracked, revealing important correlations between severity and postoperative complications. Preliminary biological analyses identified potential biomarkers associated with hypospadias severity and recovery. The full details of these results will be presented in a separate publication. The comprehensive database is continuously updated with longitudinal follow-up data, supporting future translational research. Conclusions: The Hypospadias Biobank Cohort represents a groundbreaking resource for translational research, offering unprecedented insights into the clinical and phenotypic spectrum of hypospadias. By enabling the refinement of classification systems and the development of evidence-based surgical techniques, the HBC has the potential to transform the management of this congenital condition. Ongoing research leveraging the HBC will further unravel the complex interplay among clinical presentation, surgical interventions, and patient outcomes, paving the way for personalized care strategies and improved long-term results.

Background: Hypospadias is a common congenital condition in male infants, characterised by incomplete development of the underside of the penile shaft. Genetic factors play a major role in its development. Therefore, studying genetic contributions, especially in familial cases, can enhance our understanding of disease causes and guide targeted interventions. Materials and Methods: Through a structured biobank for hypospadias, we collected blood samples from individuals with familial hypospadias and their relatives. Whole-genome sequencing (WGS) was performed on 27 individuals across seven families to identify potential genetic causes. Bioinformatics analysis, including the GEMINI tool, was used to assess inheritance patterns of single-nucleotide variants (SNVs) within families and identify potential causative SNVs. Results: We identified three likely pathogenic variants in genes not previously associated with hypospadias in EIF2B5, INO80, and ACADVL genes, in three index patients. These variants co-segregated with the condition within the families. Additionally, we detected variants of uncertain significance in hypospadias-related gene families (DNAH12 and LHFP) and in other genes, such as COL6A3, which may cause the phenotype. No potential causative variants were found in two of the seven studied families, indicating the need for further analysis, including the assessment of copy number variants (CNVs). Functional studies will be crucial to establish the role of the identified variants in the development of hypospadias. Conclusions: This study underscores the importance of disease biobanking and genetic analysis in identifying potential underlying causes of congenital conditions, such as hypospadias. The identified variants provide new opportunities for functional research and may enhance our understanding of hypospadias pathophysiology. These findings broaden the genetic landscape of hypospadias and lay the groundwork for functional validation, improved risk assessment, and personalised medicine strategies.

Background: The purpose of the study is to determine the effectiveness of web-based self-care management program for type 2 diabetes mellitus through sharing evidenced-based information about Diabetes through the use of a web-based module. Materials and methods: The study used the quasi-experimental pre and posttest design to determine the effectiveness of a web-based self-care management program in the management of patients with type 2 Diabetes mellitus (DM). The study was conducted in three phases and acquired 30 purposively selected type 2 DM adult patients. The study used a web-based self-care management program that included basic information about Type 2 Diabetes mellitus using three designed modules specifically for diet, exercise and drug management. Results: The patient status during the pre and post-intervention phase is an FBS reading of 152 mg/dl or diabetes stage to pre-diabetes stage (119 mg/dl), normal BMI (22), low risk for obesity WHR and barely satisfactory to satisfactory level of knowledge to diabetes and DM management. There is very significant difference (p=<000) in the pre and post FBS reading of patients and the level of knowledge to diabetes and DM management after the web based DSME while there is no significant difference in the BMI and WHR. There is very significant difference (p=<000) in the RBS readings of the patients during the 1st, 2nd and 3rd phases of the intervention of .web based DSME (p=<000) post hoc analysis with Wilcoxon Signed Rank Test revealed that there is very significant difference (p=<000) between groups. Conclusion: The use of web-based self-care management program is effective in improving FBS/RBS and level of knowledge to diabetes and DM management of patients with type 2 diabetes mellitus but needed longer intervention to improve BMI and WHR .Nurses as part of the DSME group and as health educator may use technology in giving health education to patients to improve patients self-management to diabetes.
