Exploring the burden of irritable bowel syndrome among university students in Saudi Arabia: A study on prevalence, psychological associations, and well-being.

Patients with irritable bowel syndrome (IBS) experience not only a detrimental impact on their physical health but also a significant influence on their psychological well-being. This study aimed to assess the prevalence of IBS among university students, investigating the sociodemographic and lifestyle factors influencing its onset. Furthermore, it explored the potential impact of psychological factors such as depression, anxiety, and overall well-being on the prevalence of IBS. A cross-sectional analytical study was conducted at Saudi Arabian universities in November and December 2023. To collect data, an anonymous, validated, predesigned questionnaire was used. The diagnosis of IBS was carried out using the validated Arabic version of the Rome IV questionnaire. We used the Arabic version of the World Health Organization Well-being Index to assess the participants' well-being. We used the Arabic version of the Hospital Anxiety and Depression Scale (HADS) to identify people who show clinically significant symptoms of anxiety and depression. Our study included a total of 379 university students, 46.7% were female 86.0% of participants resided in urban areas, and 7.2% had been previously diagnosed with IBS. The prevalence of IBS among participants was found to be 31.9%. We observed a significant association between marital status and IBS (χ2 = 3.95, P = .047). Furthermore, the highest prevalence of IBS was observed among students majoring in literary and scientific disciplines (χ2 = 0.952, P = .049). Individuals with IBS demonstrate a significantly higher prevalence of anxiety (71.90% vs 41.09%, P < .001) and depression (64.46% vs 42.64%, P < .001) compared to those without IBS. Furthermore, people with IBS had a slightly higher prevalence of poor well-being (38.84%) compared to those without IBS (33.72%), but this association was not statistically significant. In multivariate analysis, having a family history of IBS [OR = 1.75 (95% CI, 1.06-2.87), P = .029] having borderline anxiety [OR = 7.58, 95% CI (2.12-27.06), P = .012] and anxiety [OR = 16.07, 95% CI (4.57-56.52), P < .001], and depression [OR = 2.97, 95% CI (1.13-7.83), P = .010] were the main significant predictors of IBS among university students. The high prevalence of IBS among university students was associated with a family history of IBS as well as depression and anxiety. Increasing awareness, multidisciplinary support, and access to mental health services is required to ensure university students' well-being.

Publications in Plastic Surgery and Reconstruction: A Review from a Developing Country, Sudan.

Background: Plastic and reconstructive surgery services need to be improved in developing African countries. Research and article publications from those countries are limited. This review was conducted to identify published articles from Sudan in the area of plastic and reconstructive surgery. Methods: This review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-analysis guidelines. The Preferred Reporting Items for Systematic Reviews and Meta-analysis guidelines were used for the preparation of this systematic review. A comprehensive systematic search was performed using PubMed, ScienceDirect, and Web of Science databases. Articles published in Sudan, specifically in the area of plastic and reconstructive surgery, and written in English were included in this review. Results: The total number of articles that fulfilled the inclusion criteria was 23. The articles were written from 1969 to 2023. Only two articles were published in the 20th century. The most common study type was a retrospective study of eight articles, and the most common study area was Khartoum Teaching Hospital. Regarding the publishing journals, the number of subscription journals was six (30%), whereas open access was 17 (70%). Conclusion: This review demonstrates the lack of articles published on plastic surgery in Sudan. Further investigation is needed to determine the challenges and problems associated with possible clarifications.

Degree of Hearing Improvement and Reduction of Air-Bone Gap After Tympanoplasty in a Tertiary Hospital in Saudi Arabia.

BACKGROUND:  A clinical condition known as chronic otitis media (COM) is characterized by tympanic membrane perforation, varying degrees of hearing loss, and otorrhea that lasts for two to six weeks. COM alone or with cholesteatoma may result in ossicular chain discontinuity and ossicular erosion. The hearing restoration procedure includes repairing the eardrum and building the ossicular chain in ears with damaged ossicles. Multiple studies suggest the predictive value of preoperative air-bone gap (ABG) to detect the ossicular chain status can help with proper preoperative planning for surgery. OBJECTIVE: To determine the degree of hearing improvement and reduction in ABG after tympanoplasty and to investigate the correlation between preoperative ABG and the status of the ossicular chain during surgery. Study design, setting, and date: This retrospective hospital file-based study was conducted at Aseer Central Hospital, Southern Region, Saudi Arabia, between November 2022 and April 2023. Hospital records of patients who underwent tympanoplasty during 2018-2023 were reviewed. Eighty-five patients were diagnosed with chronic suppurative otitis media (CSOM) between 2018 and 2023. A data collection sheet was employed to record extracted data, including the patient's age, sex, hearing assessment, type of surgical intervention, and outcome. We calculated the average of ABG decibels (dB) by summing the ABG values at 500 Hz, 1000 Hz, and 2000 Hz frequencies and dividing by three. RESULTS: In the present study, data from 85 patients who underwent tympanoplasty were analyzed. Approximately one-third of the patients were in the age group of 31 to 40 years (25, 29.4%), and 50 (58.8%) of them were females. Chronic medical conditions were observed in 30 (35.3%) patients, with diabetes being reported in 19 (63.3%) of those cases. CSOM was found to be present in the left ear of 47 (56.0%) patients. Among the patients, 25 (29.4%) had subtotal perforations, 12 (14.1%) had marginal perforations, and two (2.4%) had total tympanic membrane perforations. The majority of patients (67, 78.8%) exhibited conductive hearing loss, while the remaining 18 (21.2%) had mixed hearing loss. Of the patients, 13 (15.3%) and 20 (23.5%) had fixed and disrupted ossicular chains, respectively. In terms of ossicular disruption, incudostapedial joint (ISJ) fixing (21.2%), fixed stapes (18.2%), and ISJ dislocation (18.2%) were the most prevalent kinds. Prior to operations, the mean ± SD of ABG was 22.6 ± 7.5. ABG values were 19.0 ± 9.3 on average after surgery. The statistical difference between pre- and postoperative ABG was statistically significant (paired t-test, p = 0.007), with a mean difference of -3.7. There were no significant differences between the different statuses of ossicular chains and the type of tympanic membrane perforation. CONCLUSION: This study suggests that the degree of preoperative ABG (dB) is a valuable predictor of intraoperative ossicular chain status and can aid in preoperative planning for ossicular chain reconstruction. Furthermore, the study found that the type of tympanic membrane perforation preoperatively is not a reliable indicator of the ossicular chain status. Finally, tympanoplasty is considered a beneficial surgical procedure with a significant improvement in hearing status postoperatively.

The predictors and risk factors of two-year rejection in renal transplant patients: A multicenter case-control study.

INTRODUCTION: Kidney transplantation is a definitive treatment for end-stage renal disease. It is associated with improved life expectancy and quality of life. One of the most common complications following kidney transplantation is graft rejection. To our knowledge, no previous study has identified rejection risk factors in kidney transplant recipients in Saudi Arabia. Therefore, the purpose of this study was to determine the specific risk factors of graft rejection. METHODS: A multicenter case-control study was conducted at four transplant centers in Saudi Arabia. All adult patients who underwent a renal transplant in the period between 01/01/2015 and 31/12/2021 were screened for eligibility. Included patients were categorized into two groups (cases and control) based on the occurrence of biopsy-proven rejection within two years. The primary outcome was to determine the risk factors for rejection within the first two years of transplant. Exact matching was utilized using a 1:4 ratio based on patients' age, gender, and transplant year. RESULTS: Out of 1320 screened renal transplant recipients, 816 patients were included. The overall prevalence of two-year rejection was 13.9%. In bivariate analysis, deceased donor status, the presence Donor Specific Antibody (DSA), intraoperative hypotension, serum Chloride levels, Pseudomonas aeruginosa, Candida, and any Infection within two years were linked with increased risk of two-year rejection. However, in the logistic regression analysis, DSA was identified as a significant risk for two-year rejection (Adjusted OR 2.68; 95% CI, 1.10, 6.49, p = 0.03). While, the presence of Panel-reactive antibody (PRA) and higher serum chloride levels one week prior to transplant was associated with lower odds of rejection (Adjusted OR 0.12; 95% CI, 0.03, 0.53, p = 0.005 and Adjusted OR 0.93; 95% CI, 0.86, 0.98, p = 0.02, respectively). Furthermore, blood infection, infected with Pseudomonas aeruginosa or BK virus within two years of transplant was associated with higher odds of two-year rejection (Adjusted OR 3.10; 95% CI, 1.48, 6.48, p = 0.003, Adjusted OR 3.23; 95% CI, 0.87, 11.97, p = 0.08 and Adjusted OR 2.76; 95% CI, 0.89, 8.48, p = 0.07, respectively). CONCLUSION: Our findings emphasize the need for appropriate prevention and management of infections following kidney transplantation to avoid more serious problems, such as rejection, which could significantly raise the likelihood of allograft failure and probably death. Further studies with larger sample size are needed to investigate the impact of serum chloride levels prior to transplant and intraoperative hypotension on the risk of rejection.

Postoperative Patient Pain Severity and Its Association With Anxiety, Depression, and Sleep Quality.

Introduction The experience of pain is a complex phenomenon. A patient in the acute postsurgical pain setting may feel a constant bombardment of nociceptive input from the surgical site; this in turn influences psychological factors that determine the overall emotional experience of pain, which is significant. The aim of our study was to investigate the severity of pain in postsurgical patients three days after surgery using the 100 mm visual analog scale (VAS). Methods This was a cross-sectional assessment of postoperative pain. Participants were patients between 18 and 64 years of age who had undergone a surgical procedure (laparoscopic or open surgery), three days prior to the data collection and who were admitted or discharged postoperatively at the Al Salmaniya Complex, Manama, Bahrain. Participants were asked demographic questions about whether they had laparoscopic or open surgeries and completed self-reporting scales. Patient Health Questionnaire-9 (PHQ-9) was utilized to screen for both the presence and severity of depression; Generalized Anxiety Disorder 7-item (GAD-7) was administered to screen for anxiety; the Insomnia Severity Index (ISI) was used to evaluate insomnia; and the VAS was used to evaluate pain.  Results Sixty-seven patients were recruited, with a mean age of 61.53 years (SD = 7.37). Twenty-nine (43%) were females, 38 (57%) were males, 36 (54%) underwent elective surgery, 31 (46%) underwent emergency surgery, 31 (46%) underwent laparoscopic surgery, and 36 (54%) underwent open surgery. The average score on the Brief Pain Inventory Short Form (BPISF) was 8.12 (SD = 1.16), indicating a moderate level of pain. Twenty-six (43%) patients had moderate-severe insomnia, 21 participants (31%) had no insomnia, 17 participants (25%) had subthreshold insomnia, 28 (42%) had moderate depression, five (7%) had moderate-severe depression, and 34 (51%) had severe depression. Eighteen participants (27%) had mild anxiety, 46 (69%) had moderate anxiety, and 3 (4%) had severe anxiety. Six of the participants (9%) reported moderate pain, while 61 participants (91%) reported severe pain.

The analysis of a new fractional model to the Zika virus infection with mutant.

We present a new mathematical model to analyze the dynamics of the Zika virus (ZV) disease with the mutant under the real confirmed cases in Colombia. We give the formulation of the model initially in integer order derivative and then extend it to a fractional order system in the sense of the Mittag-Leffler kernel. We study the properties of the model in the Mittag-Leffler kernel and establish the result. The basic reproduction of the fractional system is computed. The equilibrium points of the Zika virus model are obtained and found that the endemic equilibria exist when the threshold is greater than unity. Further, we show that the model does not possess the backward bifurcation phenomenon. The numerical procedure to solve the problem using the Atangana-Baleanu derivative is shown using the newly established numerical scheme. We consider the real cases of the Zika virus in Colombia outbreak are considered and simulate the model using the nonlinear least square curve fit and computed the basic reproduction number R0=0.4942, whereas in previous work (Alzahrani et al., 2021) [1], the authors computed the basic reproduction number R0=0.5447. This is due to the fact that our work in the present paper provides better fitting to the data when using the fractional order model, and indeed the result regarding the data fitting using the fractional model is better than integer order model. We give a sensitivity analysis of the parameters involved in the basic reproduction number and show them graphically. The results obtained through the present numerical method converge to its equilibrium for the fractional order, indicating the proposed scheme's reliability.

Impacts of sugarcane industrial effluent as an alternate source of irrigation on growth, chlorophyll contents and antioxidants of different canola varieties.

The sugarcane industry often utilizes effluent for irrigation purposes; however, its intricate composition and elevated metal contaminants pose a potential risk of soil and crop contamination. Consequently, it is imperative to employ effective strategies to ensure the safe utilization of this resource for crop cultivation. One such strategy involves the dilution of sugarcane industry effluent. Dilution is a practical approach to mitigate its toxicity, minimizing its adverse impact on soil and crop health. That's why the current study explored the best dilution of sugarcane industrial effluent (SW) for cultivating canola varieties. A total of 15 canola varieties were cultivated 0%, 20%, 40%, 60%, 80%, and 100% SW. Results showed that 60% SW Faisalabad Canola and Punjab Canola improved germination, shoot length, root length, shoot fresh and dry weight, root fresh and dry weight, and chlorophyll contents compared to other treatments and control. AARI Canola and CON-III showed poor growth and chlorophyll contents under 60%SW. Dunkled and Oscar cultivars showed moderate improvement in growth and chlorophyll contents under 60SW. The 60% SW can be recommended for maximum growth benefits in canola cultivars, specifically Faisalabad Canola and Punjab Canola. At 20SW, the root dry weight of Faisalabad Canola increased by 2.7%, while Punjab Canola increased by 3.4%. Canola showed the highest increase in POD activity compared to the control, with a 55.45% increase, followed by Sandal Canola, with a 43.26% increase. However, additional field-level experiments are needed to determine the best cultivars suitable for optimal growth under 80SW and 60SW irrigation conditions.

Polyphenol Fingerprint, Biological Activities, and In Silico Studies of the Medicinal Plant Cistus parviflorus L. Extract.

Cistus parviflorus L. (Cistaceae) is a medicinal plant with several folkloric applications, including being used for urinary tract infections and as a food additive. In this study, the polyphenolic diversity and the antioxidant, antidiabetic, and antimicrobial activities of the C. parviflorus methanolic extract were evaluated. Spectrophotometric and HPLC-based analyses using standard polyphenolic compounds were conducted to measure the phenolics and flavonoids in the plant extract. The in vitro DPPH, ORAC, FRAP, and α-glucosidase assays were used to evaluate the plant's antioxidant and antidiabetic activities. Furthermore, disc diffusion and MIC-based microdilution tests were applied to evaluate the antimicrobial activity of the plant against broad-spectrum microorganisms. The analysis revealed the existence of high phenolic and flavonoid quantities that were measured at 302.59 ± 0.6 µg GAE and 134.3 ± 0.5 µg RE, respectively. The HPLC-based analysis revealed the existence of 18 phenolic acids and 8 flavonoids. The major phenolic acid was ellagic acid (169.03 ppm), while catechin was the major flavonoid (91.80 ppm). Remarkable antioxidant activity was measured using three different assays: DPPH, ORAC, and FRAP. Furthermore, strong inhibition of α-glucosidase compared to acarbose was recorded for the plant extract (IC50 0.924 ± 0.6). The results showed that C. parviflorus's extract had a strong anti-Escherichia coli effect with MIC value of 0.98 µg\mL and IZD value of 32.2 ± 0.58 mm compared to 25.3 ± 0.18 mm for gentamycin, the positive control. Moreover, Aspergillus niger, Aspergillus fumigatus, Staphylococcus aureus, Streptococcus pyogenes, and Salmonella typhimurium all showed significant growth inhibition in response to the extract, a result that may be related to the use of the plant in traditional medicine to treat urinary tract infections. The docking study indicated the higher binding affinity of the major identified compounds, i.e., ellagic acid, rutin, naringin, catechin, and punicalagin, to the S. aureus gyrase-DNA complex, which might suggest the possible mechanisms of the plant as antimicrobial agents.

Short Tandem Repeat (STR) DNA Analysis for Using Coffee Cups As Forensic Medicine Evidence.

Introduction Forensic science has continually evolved, with innovations in DNA analysis techniques playing a pivotal role in improving the accuracy and reliability of criminal investigations. Short tandem repeats (STRs) have been a game-changer in forensic science, offering unique genetic markers to pinpoint individual identities. This study explores the application of STR DNA analysis to an unconventional source: coffee cups. Materials and methods In a study involving 16 unrelated, healthy individuals aged 26 to 32, DNA was investigated from coffee cups and mouth cavities, comparing the results to a previous coffee cup DNA study. Buccal swabs provided reference samples, air-dried for 10 minutes, and stored at 20°C. DNA quantification revealed a significant decrease in coffee cup samples (0.015 to 0.049 ng/µL) compared to the reference, with no DNA in negative controls. Some STR loci displayed inhibition and lower heterozygosity in the research samples. Ethical approval (REC 53-592) and adherence to the Declaration of Helsinki ensured ethical standards. This research highlights potential challenges in obtaining efficient DNA profiles from various sources. Results There was a significant variation in DNA concentrations among the different cup types, with ceramic cups yielding the highest concentrations. Moreover, the DNA profiling outcomes ranged from full profiles, which allow for precise individual identification, to partial profiles, which pose challenges for conclusive matches. These findings have profound implications for forensic science. The study demonstrates the potential of coffee cups as sources of DNA evidence in criminal investigations, even if partial profiles are obtained. Such evidence can assist in suspect identification, victim profiling, and corroborating witness statements. Conclusion This study highlights the application of STR DNA analysis for coffee cups, opening new avenues for forensic investigations and highlighting the need for continued research and development in this exciting field. This observation aligns with existing research on DNA recovery from various surfaces, and further research is warranted to refine the methodology, consider usage patterns, and address ethical and legal concerns regarding the collection and use of DNA evidence from common objects.

Honokiol is a neolignan biphenol found in aerial parts of the Magnolia plant species. The Magnolia plant species traditionally belong to China and have been used for centuries to treat many pathological conditions. Honokiol mitigates the severity of several pathological conditions and has the potential to work as an anti-inflammatory, anti-angiogenic, anticancer, antioxidant, and neurotherapeutic agent. It has a long history of being employed in the healthcare practices of Southeast Asia, but in recent years, a greater scope of research has been conducted on it. Plenty of experimental evidence suggests it could be beneficial as a neuroprotective bioactive molecule. Honokiol has several pharmacological effects, leading to its exploration as a potential therapy for neurological diseases (NDs), including Alzheimer's disease (AD), Parkinson's disease (PD), cerebral ischemia, anxiety, depression, spinal cord injury, and so on. So, based on the previous experimentation reports, our goal is to discuss the neuroprotective properties of honokiol. Besides, honokiol derivatives have been highlighted recently as possible therapeutic options for NDs. So, this review focuses on honokiol's neurotherapeutic actions and toxicological profile to determine their safety and potential use in neurotherapeutics.

Prevalence of Sleep-Disordered Breathing and Its Association With Orofacial Symptoms Among Primary School Children in the Aseer Region, Saudi Arabia.

Background Sleep-disordered breathing (SDB) is a significant health concern affecting both adults and children. However, limited research has focused on SDB and its association with orofacial symptoms in primary school children in the Aseer Region, Saudi Arabia. Understanding the prevalence and impact of SDB in this specific population is crucial for early detection and intervention. The study aims to investigate the prevalence of SDB and its associations with orofacial symptoms among primary school children. Method A descriptive cross-sectional survey was conducted, involving 307 primary school children aged six to 12 years in the Aseer Region. Data was collected through a web-based questionnaire, analyzing demographic information, orofacial symptoms, sleep apnea symptoms, general symptoms, growth-related symptoms, and behavioral symptoms. Results The study showed a balanced gender distribution, with 67.8% of children falling between ages six and nine years. Most children were Saudi nationals, and 58.6% were enrolled in primary education. Orofacial symptoms were reported by 63.5% of children, with finger-sucking and grinding teeth while sleeping being the most common. Sleep apnea symptoms affected 44.3% of children, with snoring being the prevalent symptom. General symptoms were reported by 45% of children, with daytime sleepiness being the most common. Approximately 44.6% of children exhibited sleepiness and growth-related symptoms. No statistically significant relationship was found between age and the occurrence of these symptoms. Conclusion The study offers valuable insights into the prevalence of SDB and its associations with orofacial symptoms among primary school children in the Aseer Region. To truly gauge the impact of interventions on SDB, further research with therapeutic interventions is warranted. In the meantime, targeted strategies and awareness initiatives are needed to address SDB in this population and enhance their overall health and quality of life.

Bronchiolitis in Infants; Five Years' Experience of a Teaching Hospital.

Background: Bronchiolitis is a clinical syndrome affecting the lower respiratory tract of infants and toddlers <2 years old. Variability in clinical profile and response to therapy in children with Bronchiolitis calls for studying the different clinical aspects of local patient population. Aim: The goal of our study is to determine the clinical presentation, past medical history, hospitalization course and prognosis in children below two years of age who have been hospitalized in King Fahad University Hospital over the last five years. Materials and Methods: A retrospective chart review based on electronic health records of all Bronchiolitis-related hospitalization of infants and toddlers below two years of age, covering the period between January 1, 2015, to April 26, 2020. Results: Out of a total of 446 children <2 years of age, 202 were female (45.4%), and 243 were male (54.6%). Although the length of hospital stay was almost equal between the sexes, there was a significant (p-value=0.01) increase in length of intensive care unit stay among females compared to males. Furthermore, there was a significant prolongation in the duration of ventilator usage among females (p value = 0.062). Out of fifty-five patients admitted to the ICU, 83.63% of them were 12 months of age and below. Conclusion: Our results show a significant increase in length of ICU and ventilator use among females compared to males. It also shows that infants younger than 12 months account for most ICU admissions. These findings, among many others, may help pediatricians formulate a better diagnostic and therapeutic pathways.

Assessing the Knowledge and Practices of Burn First Aid in Al-Baha Region, Saudi Arabia.

Background Burns are a prevalent type of injury that can result in substantial morbidity and mortality. Burn first aid knowledge is essential for reducing its complications and improving outcomes. However, evidence of the amount of burn first aid knowledge among the general population in many nations is sparse. Methodology A cross-sectional survey was conducted among 346 persons over the age of 18 from the Al-Baha region of Saudi Arabia. The participants' knowledge of first aid for burns, including the appropriate steps to take in the event of a burn, the types of burns, and the proper application of burn dressings was assessed using a structured questionnaire. Results The majority of participants (73.6%) had inadequate knowledge of first aid for burns, while only 26.4% had adequate knowledge. The most common misconception among participants was the use of toothpaste, honey, or ice for burn treatment, which is not recommended. Additionally, hot water was the main cause of burning in this study. Conclusions This study underscores the necessity for targeted education and awareness-raising activities to improve the general population's knowledge and habits about first aid for burns. Such programs can be tailored to clarify myths and misunderstandings regarding burn treatment and encourage evidence-based strategies for preventing and treating burns.

Knowledge, Attitude, and Practice of Diabetic Foot Ulcer Care in Asser Region: A Cross-Sectional Study.

Background Foot problems continue to be the leading cause of hospital admissions among people with diabetes. The objective of this study was to explore and assess the knowledge and attitudes of individuals about diabetic foot ulcers in the Asser region, Saudi Arabia. Methodology An anonymous, online, cross-sectional survey was conducted. The questionnaire was distributed through commonly used social media platforms such as Instagram, Facebook, and Twitter. Results A total of 445 participants were included in this survey. Overall, 37.1% (165) were aged 18-25 years, 64.3% (286) were women, and 75.7% (337) had university-level education. A significant number of participants had relatives with diabetes (57.1%, 254), while a smaller percentage reported having diabetes themselves (7.3%, 33), and a substantial proportion were neither diabetic nor had a relative with diabetes (35.6%, (158). Nearly two-fifths of the participants (37.8%, 168) received information about diabetes and diabetic foot care from physicians, and 34.1% (152) of the participants accessed information online. There were significant differences between those who did not have diabetes mellitus (DM) and those who had DM or whose relatives were diabetic in responses to the following questions: "Do you think that diabetes may cause gangrene in the foot?" (50.9% (205) vs. 45.7% (32), p = 0.019), "Do you think that preventing diabetic foot ulcers is more important than treating diabetic foot ulcers?" (60.8% (228) vs. 46.9% (60), p = 0.002), and "Do you think it is important to constantly monitor diabetic foot wounds?" (63.1% (200) vs. 30.4% (17), p < 0.001). There was a statistically significant difference between groups in the practice of daily foot checks, washing feet, moisturizing feet, keeping feet away from hot and cold, and nail care (p < 0.001). Conclusions The participants in the study showed a lack of knowledge regarding diabetic foot care, indicating the potential for better outcomes through the implementation of enhanced health education programs.

Bioinspired fabrication of zinc hydroxide-based nanostructure from lignocellulosic biomass Litchi chinensis leaves and its efficacy evaluation on antibacterial, antioxidant, and anticancer activity.

Zinc-based nanostructures are known for their numerous potential biomedical applications. In this context, the biosynthesis of nanostructures using plant extracts has become a more sustainable and promising alternative to effectively replace conventional chemical methods while avoiding their toxic impact. In this study, following a low-temperature calcination process, a green synthesis of Zn-hydroxide-based nanostructure has been performed using an aqueous extract derived from the leaves of Litchi chinensis, which is employed as a lignocellulose waste biomass known to possess a variety of phytocompounds. The biogenic preparation of Zn-hydroxide based nanostructures is enabled by bioactive compounds present in the leaf extract, which act as reducing and capping agents. In order to evaluate its physicochemical characteristics, the produced Zn-hydroxide-based nanostructure has been subjected to several characterization techniques. Further, the multifunctional properties of the prepared Zn-hydroxide-based nanostructure have been evaluated for antioxidant, antimicrobial, and anticancer activity. The prepared nanostructure showed antibacterial efficacy against Bacillus subtilis and demonstrated its anti-biofilm activity as evaluated through the Congo red method. In addition, the antioxidant activity of the prepared nanostructure has been found to be dose-dependent, wherein 91.52 % scavenging activity could be recorded at 200 µg/ml, with an IC50 value of 45.22 µg/ml, indicating the prepared nanostructure has a high radical scavenging activity. Besides, the in vitro cytotoxicity investigation against HepG2 cell lines explored that the as-prepared nanostructure exhibited a higher cytotoxic effect and 73.21 % cell inhibition could be noticed at 25.6 µg/ml with an IC50 of 2.58 µg/ml. On the contrary, it was found to be significantly lower in the case of HEK-293 cell lines, wherein ~47.64 % inhibition could be noticed at the same concentration. These findings might be further extended to develop unique biologically derived nanostructures that can be extensively evaluated for various biomedical purposes.

Orbital and Intracranial Complications of Acute Rhinosinusitis in a Tertiary Center, Saudi Arabia.

Background Rhinosinusitis is an inflammatory condition affecting the nasal cavity's mucosa and paranasal sinuses. In rare cases, acute rhinosinusitis (ARS) might lead to significant orbital and intracranial complications. This study aims to review the patients who presented with orbital or intracranial complications of ARS and to identify the main outcomes of these complications and their prognosis. Methods In this study, a retrospective chart review of patients with orbital or intracranial complications of ARS who presented to the otolaryngology department at King Abdulaziz Medical City, Riyadh, Saudi Arabia from 2016 to 2022 was conducted. Results A total of 43 patients with orbital, intracranial, or both (orbital and intracranial) complications of ARS were included. The most involved sinuses were maxillary sinuses. The most reported orbital complications were subperiosteal abscesses, and the most reported intracranial complications were epidural abscesses. Conclusion Orbital and intracranial complications of ARS are serious and life-threatening if not recognized early and treated effectively. The majority of ARS complications in this study were orbital complications. Fortunately, most of the cases carry a favorable outcome.

Experimental and theoretical investigations of Erbium complex: DNA/BSA interaction, anticancer and antibacterial studies.

To assess the biological potential of an Er complex that contains a 2,2'-bipyridine ligand, various techniques such as multispectral and molecular modeling procedures were utilized to examine its DNA-binding ability, BSA binding affinity, antimicrobial effects, and anticancer properties. By analyzing fluorescent information and employing the vant' Hoff equation, important parameters such as the innate docking coefficient (Kb), Stern-Volmer coefficient (KSV), and thermodynamic properties including modifications in liberated energy (ΔG°), enthalpy (∆H°), and entropy (∆S°) were determined. The trial findings suggest that the compound can bind to DNA, primarily through groove binding. Additionally, the engagement between the Er compound and the protein BSA was examined using emission spectroscopy technique, revealing a powerful binding affinity between the compound and BSA. The Er complex binds to BSA primarily via hydrogen links and van der Waals forces, as indicated by the adverse values of ΔH° and ∆S°. Through a static quenching process, the complex significantly reduces the intrinsic fluorescence of BSA. Molecular binding calculations and rivalrous binding trials confirm that this compound dock to hydrophobic remains found in site III of BSA. Additionally, the Er complex demonstrates promising results in terms of its anticancer and antimicrobial activities based on screening tests.

Bilateral enlarged concha bullosa: a case report and literature review.

Concha Bullosa (CB) is a common sinonasal anatomical variant, which commonly extends into the middle turbinate. Generally, patients presenting with CB are asymptomatic and often incidentally diagnosed with a non-contrast computed tomography scan of the paranasal sinuses. In cases of extensive pneumatization, large CB may cause significant signs and symptoms-commonly, headaches, nasal obstruction, and hyposmia. With only a few reported cases of large CB in the literature; we herein, report a rare case of an unusually massive bilateral CB that resulted in complete obstruction of the left nasal cavity and partial obstruction of the right nasal cavity, in addition to a review of relevant literature.

A comprehensive insight into the role of small nucleolar RNAs (snoRNAs) and SNHGs in human cancers.

Long non-coding RNAs (lncRNAs), which comprise most non-coding RNAs (ncRNAs), have recently become a focus of cancer research. How many functional ncRNAs exist is still a matter of debate. Although insufficient evidence supports that most lncRNAs function as transcriptional by-products, it is widely known that an increasing number of lncRNAs play essential roles in cells. Small nucleolar RNAs (snoRNAs), 60-300 nucleotides in length, have been better studied than long non-coding RNAs (lncRNAs) and are predominantly present in the nucleolus. Most snoRNAs are encoded in introns of protein- and non-protein-coding genes called small nucleolar RNA host genes (SNHGs). In this article, we explore the biology and characteristics of SNHGs and their role in developing human malignancies. In addition, we provide an update on the ability of these snoRNAs to serve as prognostic and diagnostic variables in various forms of cancer.
