RESUMO

Diabetes mellitus is a major global health concern in the current scenario which is chiefly characterized by the rise in blood sugar levels or hyperglycemia. In the context, DPP4 enzyme plays a critical role in glucose homeostasis. DPP4 targets and inactivates incretin hormones such as glucagon-like peptide-1 (GLP-1) and gastric inhibitory polypeptide (GIP) as physiological substrates, which are essential to regulate the amount of insulin that is secreted after eating. Since the inactivation of incretins occurs, the hyperglycemic conditions continue to rise, and result in adverse physiological conditions linked with diabetes mellitus. Hence, inhibition of DPP4 has been the center of focus in the present antidiabetic studies. Although few DPP4 inhibitor drugs, such as alogliptin, saxagliptin, linagliptin, and sitagliptin, are available, their adverse effects on human metabolism are undeniable. Therefore, it becomes essential for the phytochemical intervention of the disease using computational methods prior to performing in vitro and in vivo studies. In this regard, we used an in-silico approach involving molecular docking, molecular dynamics simulations, and binding free energy calculations to investigate the inhibitory potential of Ocimum tenuiflorum phytocompounds against DPP4. In this regard, three phytocompounds (1S-α-pinene, ß-pinene, and dehydro-p-cymene) from O. tenuiflorum have been discovered as the potential inhibitors of the DPP4 protein. To summarize, from our in-silico experiment outcomes, we propose dehydro-p-cymene as the potential lead inhibitor of DPP4 protein, thereby discovering new a phytocompound for the effective management of hyperglycemia and diabetes mellitus. The reported compound can be taken for in vitro and in vivo analyses in near future.

RESUMO

Coumarin derivatives are proven for their therapeutic uses in several human diseases and disorders such as inflammation, neurodegenerative disorders, cancer, fertility, and microbial infections. Coumarin derivatives and coumarin-based scaffolds gained renewed attention for treating diabetes mellitus. The current decade witnessed the inhibiting potential of coumarin derivatives and coumarin-based scaffolds against α-glucosidase and α-amylase for the management of postprandial hyperglycemia. Hyperglycemia is a condition where an excessive amount of glucose circulates in the bloodstream. It occurs when the body lacks enough insulin or is unable to correctly utilize it. With open-source and free in silico tools, we have investigated novel 80 coumarin derivatives for their inhibitory potential against α-glucosidase and α-amylase and identified a coumarin derivative, CD-59, as a potential dual inhibitor. The ligand-based 3D pharmacophore detection and search is utilized to discover diverse coumarin-like compounds and new chemical scaffolds for the dual inhibition of α-glucosidase and α-amylase. In this regard, four novel coumarin-like compounds from the ZINC database have been discovered as the potential dual inhibitors of α-glucosidase and α-amylase (ZINC02789441 and ZINC40949448 with scaffold thiophenyl chromene carboxamide, ZINC13496808 with triazino indol thio phenylacetamide, and ZINC09781623 with chromenyl thiazole). To summarize, we propose that a coumarin derivative, CD-59, and ZINC02789441 from the ZINC database will serve as potential lead molecules with dual inhibition activity against α-glucosidase and α-amylase, thereby discovering new drugs for the effective management of postprandial hyperglycemia. From the reported scaffold, the synthesis of several novel compounds can also be performed, which can be used for drug discovery.

RESUMO

Background: Acute childhood diarrhea is one of the most common causes of dehydration, and if severe, can potentially lead to death as well. The present study was aimed at evaluating the knowledge and attitudes of community pharmacy professionals towards the management of acute childhood diarrhea and comparing them with their actual practices in Jazan Province, Kingdom of Saudi Arabia (K.S.A). Methods: Simulated patient visits and a cross-sectional survey making use of a 27-item self-report questionnaire were conducted amongst a sample of 303 community pharmacy professionals (51.2 % male and 48.8 % female) with an age range of 25-56 years, between August 1 and December 1, 2021, in Jazan Province, Saudi Arabia. Convenience sampling technique was used for the recruitment of the participants. Results: Significant positive correlations were seen between knowledge score (self-report survey) and practice score (simulated patient visit) regarding patients' history taking (r = 0.65; p < 0.01), drug recommendations (r = 0.71; p < 0.01) and providing information regarding food and fluid intake (r = 0.44; p < 0.01). The alpha coefficients for all the items of the survey instrument were noted to be greater than (or) equal to the 0.70 threshold for almost all sections, hence indicating good reliability and internal consistency of the developed scale. Conclusion: In the present study, even though we observed improved participants' performance during the self report survey, their performance level greatly dropped in actual practice. This warrants for a need for educational programs to improve their actual dispensing practices. The present study has also shown simulated patient visits to be a reliable, simple and a robust method of assessing the actual dispensing practices of community pharmacy professionals.

RESUMO

Objective To quantify the prevalence of depression, anxiety, and post-traumatic stress disorder (PTSD) among ICU survivors in the Jazan region, Saudi Arabia, and explore the correlational relationships among these conditions to inform targeted mental health interventions in this unique regional context. Methods The study employed a cross-sectional observational design to assess ICU survivors from two major hospitals in the Jazan Region: Prince Mohammed Bin Nasser Hospital and King Fahad Central Hospital. One hundred participants were interviewed face-to-face to gather detailed insights into their post-ICU experiences. We employed the hospital anxiety and depression scale (HADS) and the post-trauma symptom scale (PTSS-10) to systematically assess the psychological impacts of anxiety, depression, and PTSD among participants. Results The demographic breakdown of participants showed a youthful skew, with 37% under 35 years, 49% aged between 36-60 years, and only 14% over 60 years, contrasting with typical ICU demographics, which generally skew older. This younger distribution may influence the psychological outcomes observed. The sample was fairly gender-balanced, with 53% male and 47% female, closely reflecting the regional gender ratio of ICU admissions. Among the participants, 24% were classified as 'abnormal' and 20% as 'borderline abnormal' for anxiety, while 25% were 'borderline abnormal' and 21% 'abnormal' for depression. About 8% of participants were diagnosed with severe PTSD. Anxiety was more strongly correlated with PTSD than depression. The analysis demonstrated significant associations between demographic factors and psychological distress among ICU survivors. Females reported higher anxiety, while lower education and unemployment were associated with increased depression. Additionally, lower household income was associated with higher PTSS scores, and marital status was linked to depression, suggesting that socioeconomic factors play a critical role in post-ICU psychological recovery. Conclusion The findings emphasize the imperative need for comprehensive mental health evaluations and tailored interventions for ICU survivors in the Jazan region.

RESUMO

Introduction Functional constipation in children is described as irregular or difficult bowel motions without underlying systemic or anatomical causes. Although constipation can have a serious negative impact on a child's health and the lives of their parents. This study aimed to assess the knowledge of parents about childhood constipation, intending to reduce morbidity and mortality through increased public health education in Makkah, Saudi Arabia. Methods The current study was a web-based, descriptive cross-sectional study. The data were obtained from May 2023 to November 2023 through an online questionnaire directed to parents in Makkah, Saudi Arabia, and analyzed using SPSS version 27.0.1 (Armonk, NY: IBM Corp.). Results A total of 796 participants were included in the present study, of which 205 (25.8%) were males and 591 (74.2%) were females. The knowledge levels among them varied, with 11.1% correctly defining constipation and 63.6% recognizing it as a symptom. Common causes like organic and functional constipation were acknowledged by 88.4% and 81.3% of participants, respectively. Regarding practices, 27.9% recommended high-fiber foods for initial home treatment, and 42.8% acknowledged that an enema is effective for fecal impaction. In the dietary recommendations, 71.7% suggested fruits and 68.8% mentioned vegetables. Concerning attitudes, 65.1% expressed fear of childhood constipation continuing into adulthood, while 30.9% feared severe medical conditions. The internet (25.5%) and friends/relatives (23.6%) were the primary sources of information. Knowledge was significantly higher among females and those with postgraduate education. Conclusion This study highlights the variability in knowledge levels among parents, with an overall moderate understanding of childhood constipation. It emphasizes a moderate level of adherence to recommended practices related to childhood constipation, with some room for improvement in Makkah, Saudi Arabia.

RESUMO

Smart GxP inspections have gained increasing attention due to the COVID-19 pandemic, which, understandably, made it challenging for regulatory authorities to conduct on-site inspections. Smart GxP inspections are an oversight approach developed by the SFDA to enable remote compliance assessments of establishments. In this type of inspection, appropriate technical methods and tools (such as livestreaming video) are used without requiring the presence of inspectors onsite, ensuring efficient utilization of resources and the efficiency of inspection process. The objective of this research is to examine and document the shared encounters involving remote inspections and evaluations carried out by SFDA from 2020 to 2022. This will be achieved through the evaluation of the accuracy of document evaluation and the extent to which the objectives of smart GxP inspections were met. Data were collected from local and international smart inspections reports conducted by SFDA between 2020 and 2022, covering medical device manufacturers, pharmaceutical manufacturing sites, warehouses, accreditation offices, scientific offices, and food manufacturing facilities. The results indicate that smart GxP inspections were effective in achieving visit objectives, showing a high degree of document evaluation accuracy. The findings of this study support the use of smart GxP inspections as a valuable alternative to on-site inspections, offering a practical solution to regulatory compliance during the pandemic and beyond. Although the SFDA recognizes the usefulness of smart inspections in upholding regulatory oversight in the face of various challenges, it does not endorse the complete replacement of conventional on-site inspection methods. The SFDA acknowledges significant limitations associated with the current technological resources used in remote regulatory assessments, and these limitations will be explored in the relevant sections.

RESUMO

OBJECTIVES: To explore the epidemiology and patterns of pediatric trauma in addition to length of hospital stay and outcome. METHODS: A single-center retrospective study of 605 patients aged 14 years and younger was carried out from January to December 2022. The study included all patients who experienced intentional or unintentional trauma aged 14 years or below in 2022 and excluded trauma that did not prompt an emergency room visit. RESULTS: Most pediatric trauma cases involved boys (69.1%, n=418), and girls comprised only 30.9% (n=187). Trauma was most common in children one to 5 years old (41.5%, n=251). Falling from a height was the most common mode of injury in both girls and boys (n=253, 41.8%). The most common body parts involved were the extremities (n=357, 59%), followed by the head (n=210, 34.7%). Most children were transferred to hospital via emergency medical services (n=234, 38.7%). In most cases, the child was admitted to the surgical ward (n=458, 75.7%), while others were managed in the emergency department without admission (n=93, 15.4%). Most patients were stable after receiving standard care (n=558, 92.2%). CONCLUSION: To reduce health care expenses and improve public health outcomes, prioritizing preventive measures is crucial. This includes increasing public awareness, implementing safety protocols, and enacting government regulations to prevent avoidable injuries.

RESUMO

Background Undescended testis (UDT) or cryptorchidism is a common pediatric surgical presentation. The accepted time for surgical correction (orchidopexy) is when the patient is aged from six months, and should ideally be completed before one year of age. In Saudi Arabia, the median age at the time of orchidopexy is 25 months, exceeding the recommended surgery time. Objective The objective of the study was to determine the factors that cause delayed presentation of UDT among children in Saudi Arabia. Methods A cross-sectional, nationwide study targeting the general population of Saudi Arabia. The study was conducted in November 2022 using a validated questionnaire distributed through social media platforms. Results A total of 2360 participants were enrolled. Over half (54.92%) had not heard about UDT. Further, 48.5% of the participants did not know the age of UDT presentation, and 49.1% had no idea about the treatment modality. Moreover, 13.9% had known someone diagnosed with UDT, while 17.68% discovered UDT after more than a year. In addition, 1.5% had previous experience with UDT, and 22.86% were diagnosed after more than a year. There was a significantly high level of knowledge among participants who had experienced UDT. The three most common reasons for delaying the intervention for UDT patients were a lack of community awareness of UDT, parents' ignorance and neglect, and a lack of early screening programs (22.3%, 21.7%, and 19.7%, respectively). Conclusion Our data demonstrated a significant lack of awareness of UDT among the Saudi population since 1296 (54.92%) of the participants had not heard about UDT. The presence of such an awareness gap necessitates cultural education about the topic of UDT by all capable facilities, including medical schools, hospitals, and primary healthcare centers.

RESUMO

Introduction Testicular torsion (TT) is the most common urological emergency in children that requires immediate intervention. The prognosis of testicular torsion depends on the patient's time of presentation to the emergency department (ED), as well as on the time at which the diagnosis is established and treatment is initiated. Raising public awareness of testicular torsion, particularly among parents, plays a crucial role in preventing delay in presentation and reducing the frequency of orchiectomy. To this end, the study is designed to assess the level of awareness and knowledge of testicular torsion, as well as the response of parents to the scrotal pain of their children. Methods A descriptive cross-sectional study was conducted among parents in the western region of Saudi Arabia. Data was collected between the 23rd of November and the 22nd of December 2022. A simple random sampling technique was implemented. The data was collected and analyzed using SPSS software (IBM Corp., Armonk, NY). Results A total of 394 parents participated in this study. It showed that 13.5% of parents reported having a child with a previous experience of pain in the scrotum. Of them, only 25.4% previously heard about torsion of the testicles. Only 68.8% and 76.6% correctly reported that if the child complains of pain in the scrotum during working hours or over the weekend, they will drive him to the hospital immediately. Good knowledge about TT was significantly higher among children's fathers compared to mothers (66.7% vs. 33.3%) (p≤0.05).  Conclusion Testicular torsion (TT) represents significant morbidity among male patients and early identification is crucial to avoid the need for orchiectomy and all its prominent physical and psychological consequences. To improve children's well-being, we need to raise parents' awareness of TT and the potential future implications of this critical condition as it is not widely known in our community. Further studies evaluating the knowledge regarding testicular torsion among preadolescent and adolescent boys are warranted.

RESUMO

Background Foreign body aspiration (FBA) is a life-threatening event and one of the most common causes of mortality in children. As it has different clinical presentations, parental knowledge is essential for early management to prevent complications. Objectives This study was designed to assess the knowledge and practices relating to FBA in children among parents living in Makkah city, Saudi Arabia. Methods An online questionnaire was designed using Google Forms (Google LLC, Mountain View, California, United States) and distributed in October 2022 among parents living in Makkah city. After data collection, an appropriate statistical analysis was conducted. Results A total of 1087 parents enrolled in this study; 63.9% were women and the majority were married 93%. Additionally, 52% of the parents had at least three children. Moreover, 17.6% had an experience of a child having aspirated a foreign body once. The Internet was the most popular source of information on FBA (43.5%). Furthermore, the parents had poor levels of knowledge and practices related to FBA (65.4% and 78.6%, respectively). Conclusion This study reported that parental levels of knowledge of FBA and FBA practices were inadequate. There is a need to increase awareness, which will lead to better outcomes.

RESUMO

Objective: ICU workers are among the healthcare staff exposed to high occupational burnout in their daily interactions with patients, especially during the COVID-19 pandemic. This study aimed to investigate the prevalence and risk factors of burnout among ICU staff in the Jazan region of Saudi Arabia. Methods: A cross-sectional study was conducted using the Maslach Burnout Inventory (MBI), which was distributed to ICU staff between August 1 and November 30, 2021. A total of 150 ICU workers were invited to participate in the study. Results: A total of 104 ICU staff responded to the survey (69% response rate), including 62 nurses, 30 physicians, and 12 respiratory therapists. Among the respondents, 63 (61%) were female and 41 (39%) were male. The mean scores for emotional exhaustion, depersonalization, and personal accomplishment were 22.44 ± 14.92, 9.18 ± 7.44, and 29.58 ± 12.53, respectively. The ICU staff at high risk of emotional exhaustion, depersonalization, and personal accomplishment were 36%, 28%, and 47%, respectively. The leading cause of burnout among ICU staff in the study was workload, and taking a vacation was the most cited coping mechanism for occupational burnout. Conclusion: ICU staff are at high risk of emotional exhaustion, depersonalization, and lack of personal accomplishment. Policymakers should implement regulations that ensure hospitals have adequate employees to reduce the workload that leads to occupational burnout.

RESUMO

Aim: Nurses play a major role in critical care units (CCUs), providing care to critically ill patients while also facing numerous health challenges that impair their quality of life. This was especially evident during the COVID-19 pandemic. The aim of this study was to assess the professional quality of life (ProQOL) and establish the prevalence of compassion satisfaction and compassion fatigue among CCU nurses in Saudi Arabia. Methods: A cross-sectional survey of CCU nurses was conducted using the ProQOL Scale, consisting of three subscales: 1) compassion satisfaction and compassion fatigue, 2) burnout, and 3) secondary traumatic stress. The data were analyzed to obtain descriptive and inferential statistics. Results: A total of 238 ICU nurses, who were predominantly female (83%) and had a bachelor's degree (80%), participated in this study. The ProQOL subscales exhibited varied mean scores across demographic variables. Statistically significant differences were observed in the compassion satisfaction (p=0.014) of CCU nurses working in public hospitals, and in the secondary traumatic stress (p=0.006) among nurses working in night shifts. The percentage distribution of CCU nurses' individual levels for all the ProQOL subscales were within the average to high levels. Conclusion: The ProQOL was significantly affected by the COVID-19 pandemic. Furthermore, varied ProQOL mean scores across demographic characteristics suggest that interpersonal differences should be considered when developing improvement initiatives.

RESUMO

Background: Nurses play a major role in the delivery of complex and challenging critical care in intensive care units (ICUs). Assessment of work environment is essential indicators of hospital management and can be applied to workforce planning and identifying nursing profession needs. The American Association of Critical-Care Nurses (AACN) recognized six standards for a healthy work environment and developed the Healthy Work Environment Assessment Tool (HWEAT). The aim of this study was to assess the work environment of ICU nurses in Jazan, Saudi Arabia. Methods: This cross-sectional study was conducted at public and private hospitals. Data were collected using a self-administered questionnaire that included the sociodemographic characteristics and the AACN HWEAT. Data were analyzed to obtain descriptive and inferential statistics. The Mann-Whitney U and Kruskal-Wallis tests were employed to compare demographic data, on the basis of the overall mean HWEAT score. Results: The study participants were 238 ICU nurses, who were predominantly female (83%). The mean overall HWEAT score was 3.55±1.03, which is within the "good" range, and was higher for male nurses (3.66), nurses aged ≥41 years (3.76), and nurses with postgraduate education (4.04), work experiences of >10 years (3.63), and alternate work shifts (3.6). Nurses in private hospitals had significantly higher overall scores than nurses in public hospitals (3.83 vs 3.19, P<0.001). All HWEAT standards ("effective decision-making", "authentic leadership", "appropriate staffing", "true collaboration", "skilled communication", and "meaningful recognition") were rated as good (mean range, 3.43-3.63). Conclusion: The study results could assist hospitals in prioritizing the adoption of AACN HWE standards. A target benchmark of "good" was established for both the overall score and each standard, which indicates a good work environment as perceived by ICU nurses. In Addition, interpersonal differences should be considered when developing improvement initiatives.

RESUMO

The aim of this study was to assess the knowledge, sources of knowledge, attitudes (fears and misconceptions) toward epidural analgesia (EA), and practices of parturient delivery in the Jazan region of Saudi Arabia. A cross-sectional study was conducted using a self-administered survey questionnaire distributed in the antenatal care clinics of the obstetric departments of major hospitals. A total of 454 women participated in this study. Of the participants, 219 (48%) belonged to the 31 to 40-year age group and 134 (30%) to the 21 to 30-year age group. Most participants (344, 76%) had a bachelor's degree. The prevalence of epidural catheter use was 23.6% among pregnant women. Statistically significant differences in educational level and residence were found between the women (p < 0.001). The two most common sources of information cited by the pregnant women were healthcare staff and family and friends. The most common motive reported by women was to relieve labor pain effectively, and the most frequently cited barriers preventing women from receiving EA were the possibility of injury to important organs and the inability to walk after EA. The present study demonstrates a low level of knowledge about EA among pregnant women in the region. More awareness and guidance about EA are warranted.

RESUMO

Fermented food plays a major role in gastrointestinal health, as well as possesses other health benefits, such as beneficiary effects in the management of diabetes. Probiotics are thought to be viable sources for enhancing the microbiome of the human gut. In the present study, using biochemical, physiological, and molecular approaches, the isolated Lactobacillus spp. from dosa batter were identified. The cell-free supernatant (CS), cell-free extract (CE), and intact cells (IC) were evaluated for their inhibitory potential against the carbohydrate hydrolyzing enzymes α-glucosidase and α-amylase. Then, 16S rDNA amplification and sequencing were used to identify the species. A homology search in NCBI database was performed that suggests the isolates are >95% similar to Limosilactobacillus fermentum and Lacticaseibacillus casei. Different standard parameters were used to evaluate the probiotic potential of strains RAMULAB07, RAMULAB08, RAMULAB09, RAMULAB10, RAMULAB11, and RAMULAB12. The strains expressed a significant tolerance to the gastric and intestinal juices with a higher survival rate (>98%). A high adhesion capability was observed by the isolates exhibited through hydrophobicity (>65%), aggregation assays (>75%), and adherence assay on HT-29 cells (>82%) and buccal epithelial cells. In addition, the isolates expressed antibacterial and antibiotic properties. Safety assessments (DNase and hemolytic assay) revealed that the isolates could be classified as safe. α-glucosidase and α-amylase inhibition of the isolates for CS, CE, and IC ranged from 7.50% to 65.01% and 20.21% to 56.91%, respectively. The results suggest that these species have exceptional antidiabetic potential, which may be explained by their use as foods that can have health-enhancing effects beyond basic nutrition.

RESUMO

OBJECTIVES: Septic shock, defined as sepsis with hypotension not responding to fluid resuscitation or requiring vasopressor support, results in the worst outcomes in sepsis patients. This subtype of the patient is often difficult to detect. The shock index (SI) has demonstrated the potential for predicting hemodynamic compromise and collapse and predicting patient outcomes in multiple medical and surgical settings. In our study, we assessed the utility of the SI as a hemodynamic screening tool to identify patients likely to fail to respond to fluids and ultimately to be diagnosed with septic shock. METHODOLOGY: A single-center cross-sectional analysis of patients presenting with hypotension and septicemia over 1 year. The study was conducted using the electronic medical records of the emergency department patients presenting to King Saud University Medical City. The charts were reviewed from 2 May 2015 to 24 April 2016 using the local medical registry. The study was approved by the hospital institutional review board (IRB). Data extraction was performed using a standardized form. RESULTS: The area under the curve was 0.77 (P < 0.001) for the prediction of hemodynamic collapse. An initial SI ≥0.875 had a sensitivity of 81% and a specificity of 72% for the identification of patients in whom fluid resuscitation would fail. CONCLUSIONS: Based on our findings, we found that the SI was a reliable screening tool for the identification of hypotensive patients with sepsis who would ultimately be diagnosed with septic shock.
