Targeted therapies for HPV-associated cervical cancer: Harnessing the potential of exosome-based chipsets in combating leukemia and HPV-mediated cervical cancer.

Exosomes play a crucial role in intercellular communication and have emerged as significant vehicles for transporting disease-specific biomarkers. This feature provides profound insights into the progression of diseases and the responses of patients to treatments. For example, in leukemia, exosomes convey critical information through the carriage of specific proteins and nucleic acids. In the case of human papillomavirus (HPV)-mediated cervical cancer, exosomes are particularly useful for noninvasive detection as they transport high-risk HPV DNA and specific biomolecules, which can be indicators of the disease. Despite their vast potential, there are several challenges associated with the use of exosomes in medical diagnostics. These include their inherent heterogeneity, the need for enhanced sensitivity in detection methods, the establishment of standardization protocols, and the requirement for cost-effective scalability in their application. Addressing these challenges is crucial for the effective implementation of exosome-based diagnostics. Future research and development are geared towards overcoming these obstacles. Efforts are concentrated on refining the processes of biomarker discovery, establishing comprehensive regulatory frameworks, developing convenient point-of-care devices, exploring methods for multimodal detection, and conducting extensive clinical trials. The ultimate goal of these efforts is to inaugurate a new era of precision diagnostics within healthcare. This would significantly improve patient outcomes and reduce the burden of diseases such as leukemia and HPV-mediated cervical cancer. The integration of exosomes with cutting-edge technology holds the promise of significantly reinforcing the foundations of healthcare, leading to enhanced diagnostic accuracy, better disease monitoring, and more personalized therapeutic approaches.

Nurse Who Had MERS-CoV Complications with A Near-Death Experience during Pregnancy: A Narrative Analysis.

BACKGROUND: According to prevailing views in neuroscience, near-death experiences (NDE) occurring after severe head trauma, critical illness, or coma are often life-transforming experiences in which no awareness or sensory experience of any kind is possible. Although there are general patterns, each case is quite different from the other and requires accurate recording and reporting to potentially explain the phenomenon. AIM: This narrative study aimed to explore a pregnant woman's NDE due to complications from MERS-CoV. METHODS: This was a qualitative narrative study with the administration of two unstructured interviews. After the second interview, the participant completed the Greyson NDE scale, presented through descriptive statistics. Qualitative data were analyzed using Labov's model of narrative analysis through abstract, orientation, complicating action, evaluation, resolution, and coda. RESULTS: The Greyson scale resulted in a total score of 12, confirming that the patient had experienced an NDE. Labov's model of narrative analysis revealed that the patient's experience was not limited to the NDE but had implications for her recovery and life. The patient experienced all three types of NDEs: out-of-body, transcendental, including the transition of consciousness to another dimension, and a combined experience. She also suffered from prolonged hallucinations, neuropathy, and post-intensive care syndrome (PICS). At the same time, the patient experienced what is known as NDE aftereffects, which are caused by a change in beliefs and values; she began to lead a more altruistic life and became interested in the meaning of life. CONCLUSIONS: NDE survivors should be encouraged to talk more and share their stories with others if they wish. This study not only investigates the NDE but also considerably adds to the existing literature by integrating a unique cultural view from a country outside of the US and other Western nations, and it highlights the significant role of healthcare providers in NDEs and the importance of communication with comatose patients. It underscores the need for compassion when dealing with patients with NDEs.

Biosynthesis, characterization, magnetic hyperthermia, and in vitro toxicity evaluation of quercetin-loaded magnetoliposome lipid bilayer hybrid system on MCF-7 breast cancer.

Novel biocompatible and effective hyperthermia (HT) treatment materials for breast cancer therapeutic have recently attracting researchers, because of their effective ablation of cancer cells and negligible damage to healthy cells. Magnetoliposome (MLs) have numerous possibilities for utilize in cancer treatment, including smart drug delivery (SDD) mediated through alternating magnetic fields (AMF). In this work, magnesium ferrite (MgFe2O4) encapsulated with liposomes lipid bilayer (MLs), Quercetin (Q)-loaded MgFe2O4@Liposomes (Q-MLs) nano-hybrid system were successfully synthesized for magnetic hyperthermia (MHT) and SDD applications. The hybrid system was well-investigated by different techniques using X-ray diffraction (XRD), Fourier transforms infrared spectroscopy (FT-IR), Energy dispersive X-ray (EDX), Vibrating sample magnetometer (VSM), Transmission electron microscope (TEM), and Zeta Potential (ZP). The characterization results confirmed the improving quercetin-loading on the MLs surface. TEM analysis indicated the synthesized MgFe2O4, MLs, and Q-MLs were spherical with an average size of 23.7, 35.5, and 329.5 nm, respectively. The VSM results revealed that the MgFe2O4 exhibit excellent and effective saturation magnetization (MS) (40.5 emu/g). Quercetin drug loading and entrapment efficiency were found to be equal to 2.1 ± 0.1% and 42.3 ± 2.2%, respectively. The in-vitro Q release from Q-loaded MLs was found 40.2% at pH 5.1 and 69.87% at pH 7.4, verifying the Q-loading pH sensitivity. The MLs and Q-MLs hybrid system as MHT agents exhibit specific absorption rate (SAR) values of 197 and 205 W/g, correspondingly. Furthermore, the Q-MLs cytotoxicity was studied on the MCF-7 breast cancer cell line, and the obtained data demonstrated that the Q-MLs have a high cytotoxicity effect compared to MLs and free Q.

Diabetes education self-management intervention in improving self-efficacy for people with type 2 diabetes in the Gulf Cooperation Council countries: A systematic review.

AIMS: This research aims to evaluate the effectiveness of diabetes education self-management intervention for improving self-efficacy for people with type 2 diabetes mellitus in the Gulf Cooperation Council countries. METHODS: The Joanna Briggs Institute's methodology was applied to conduct a systematic review of type 2 diabetes interventions published from 2012 to 2022. This involved searching major databases, including Ovid, CINAHL, Scopus, Web of Science, and PubMed, with specific inclusion and exclusion criteria. The focus was on studies involving adults aged 18 or older with a Type 2 Diabetes (T2D) diagnosis, randomized controlled trials, and full-text English-language articles, while excluding materials such as editorials and conference abstracts. RESULTS: A total of 689 relevant articles initially retrieved; ultimately, only five studies met the inclusion criteria of this review. All five included studies were randomised control trials, and all five studies indicated that there was a significant and positive impact of diabetes education self-management intervention on diet and physical activities. Furthermore, three of the included studies indicated that interventions led to a substantial reduction in the levels of glycosylated haemoglobin (HbA1c) among people with type 2 diabetes. CONCLUSIONS: Diabetes education is an effective way of improving the health outcomes of people with type 2 diabetes. Diabetes education self-management interventions significantly increase the self-efficacy of people with Type 2 Diabetes (T2D) by enabling them to effectively control their blood glucose levels. Therefore, this study recommended that the GCC countries need to implement education intervention programmes to help and support people with Type 2 Diabetes.

Lupenone, a wonder chemical obtained from Euphorbia segetalis to boost affinity for the transcriptional factor escalating drought-tolerance in Solanum Lycopersicum: A cutting-edge computational biology approach.

Drought is the single greatest abiotic factor influencing crop yield worldwide. Plants remain in one area for extended periods, making them vulnerable to natural and man-made influences. Understanding plant drought responses will help us develop strategies for breeding drought-resistant crops. Large proteome analysis revealed that leaf and root tissue proteins respond to drought differently depending on the plant's genotype. Commonly known as tomatoes, Solanum Lycopersicum is a globally important vegetable crop. However, drought stress is one of the most significant obstacles to tomato production, making the development of cultivars adapted to dry conditions an essential goal of agricultural biotechnology. Breeders have put quite a lot of time and effort into the tomato to increase its productivity, adaptability, and resistance to biotic and abiotic challenges. However, conventional tomato breeding has only improved drought resistance due to the complexity of drought traits. The resilience of tomatoes under drought stress has been the subject of extensive study. Using contemporary sequencing approaches like genomics, transcriptomics, proteomics, and metabolomics has dramatically aided in discovering drought-responsive genes. One of the most prominent families of plant transcription factors, WRKY genes, plays a crucial role in plant growth and development in response to natural and abiotic stimuli. To develop plants that can withstand both biotic and abiotic stress, understanding the relationships between WRKY-proteins (transcription factors) and other proteins and ligands in plant cells is essential. This is despite the fact that tomatoes have a long history of domestication. This research aims to utilize Lupenone, a hormone produced in plant roots in response to stress, to increase drought resistance in plants. Lupenone exhibits a strong affinity for the WRKY protein at -9.64 kcal/mol. Molecular docking and modeling studies show that these polyphenols have a significant role in making Solanum Lycopersicum drought-resistant and improving the quality of its fruit. As a result of climate change, droughts are occurring more frequently and persisting for more extended periods, making it necessary to breed crops resistant to drought. While considerable variability for tolerance exists in wild cousins, little is known about the processes and essential genes influencing drought tolerance in cultivated tomato species.

Quality by design for sumatriptan loaded nano-ethosomal mucoadhesive gel for the therapeutic management of nitroglycerin induced migraine.

Migraine is a progressive neurological condition often accompanied by nausea and vomiting. Various drugs have recently been used in the treatment of migraine, including sumatriptan (SUT). However, SUT has poor pharmacological effects mainly due to its reduced permeability, blood brain barrier (BBB) effect, half-life and bioavailability. Herein, we developed SUT loaded nano-ethosomes (SUT-NEs) for intranasal (IN) delivery, after their incorporation into chitosan based mucoadhesive gel (SUT-NEsG). The observed mean particle size of SUT-NEs was 109.45 ± 4.03 nm with spherical morphology, mono dispersion (0.191 ± 0.001), negatively charged (-20.90 ± 1.98 mV) and with excellent entrapment efficiency (96.90 ± 1.85 %). Fourier-transform infrared (FTIR) spectra have depicted the compatibility of the components. Moreover, SUT-NEsG was homogeneous having suitable viscosity and mucoadhesive strength. In vitro release and ex vivo permeation analysis showed sustained release and improved permeation of the SUT-NEsG, respectively. Additionally, histopathological studies of nasal membrane affirmed the safety of SUT-NEsG after IN application. In vivo pharmacokinetic study demonstrated improved brain bioavailability of SUT-NEsG as compared to orally administered sumatriptan solution (SUT-SL). Furthermore, significantly enhanced pharmacological effect of SUT-NEsG was observed in behavioral and biochemical analysis, immunohistochemistry for NF-κB, and enzyme linked immuno assay (ELISA) for IL-1ß and TNF-α in Nitroglycerin (NTG) induced migraine model. It can be concluded that migraine may be successfully managed through IN application of SUT-NEsG owing to the direct targeted delivery to the brain.

Formulation of fortified instant weaning food from Musa paradisiaca (banana) and Eleusine coracana.

Weaning food is a soft, easily digestible type of food other than breast milk for infants aged 6 to 24 months. The present study was conducted to develop cereal-fruit-based complementary foods for infants and evaluate the nutritional quality of such types of foods. Few researchers have focused on formulating weaning foods from locally available, nutritious, and rich ingredients without nutrient loss to reduce malnutrition and infant morbidity rates. In this study, the formulated infant food was prepared from Musa paradisiaca (Nendran banana) and Eleusine coracana (ragi). Formulated weaning food was analyzed using various standard methods, demonstrating that it could provide adequate nutrients to growing infants for their proper growth and development. The shelf life of the weaning food was also studied for a period of 3 months at ambient conditions in two different packaging materials: aluminum and plastic (low-density polyethylene or LDPE), with the aluminum foil pouch exhibiting the best shelf life. This ready-to-serve food, which is formulated and fortified with natural ingredients containing essential macronutrients and micronutrients, could be regarded as highly effective supplementary food for infants. Furthermore, this development has the potential to introduce an affordable weaning product specifically targeted at low socioeconomic groups.

Nursing internship students' knowledge regarding the care and management of people with diabetes: A multicenter cross-sectional study.

BACKGROUND: Nursing students in their final year of study will soon become responsible for the care and management of people with diabetes, and they need to be knowledgeable to provide adequate information. OBJECTIVES: The aim of this study was to assess nursing students' knowledge regarding diabetes care and management. DESIGN: A descriptive cross-sectional multicenter study. SETTINGS AND PARTICIPANTS: A convenience sample of all nursing students' internship enrolled at three government universities in Saudi Arabia. METHODS: 306 Saudi nursing students were surveyed with a self-administered questionnaire of the sociodemographic characteristics of the participants. The second part contained 23 multiple-choice questions of the Michigan Diabetes Knowledge Test. Data were collected from July to September 2022. RESULTS: The overall percentage of correct responses was 49.28 %. There was a significant difference between sex, the university attended, attendance in courses related to diabetes, and diabetes management guidelines in any course and their knowledge about diabetes care and management (p = 0.024, 0.001, 0.036, and 0.038, respectively). There was a significant difference between nursing students' general knowledge and insulin use knowledge (p = 0.001). A multiple regression analysis revealed that the university attended was the only statistically significant factor (p = 0.001). CONCLUSION: Nursing internship students are likely to be responsible for providing people with diabetes care and management once they qualify. Inappropriate knowledge negatively affects the care and management of people with diabetes. Information related to diabetic insulin therapy should be provided in more detail in the nursing curriculum.

The Experiences of Newly Graduated Nurses during Their First Year of Practice.

The present study aimed to explore the experiences of newly graduated nurses during their first year of practise. A qualitative descriptive design was employed in this study. In-depth, semi-structured interviews were conducted with newly graduated nurses to gather detailed descriptions and experiences during their transition to the workplace in the first year after graduation. Thematic analysis was utilised to identify patterns and themes in the collected data. Ethical considerations were strictly enforced throughout the study. There are two main themes: factors contributing to the integration of new nurses into the workplace and the difficulties faced by new nurses in a work environment. Within the first theme, three subthemes emerged: the positive role of trainers, the gradual handling of patients, and the benefit of pre-employment training and volunteering. The theme of difficulties faced included three subthemes: difficulty dealing with the health system and devices, fear of dealing with new patients, and difficulty applying policies and procedures in the workplace. The study provides insights into the challenges faced by newly graduated nurses and the factors that contribute to their integration into practise settings. Educational departments in hospitals' support and efficient access to policies are crucial for these nurses as they begin their early professional years.

Knowledge and Attitude of Pediatric Nurses in Saudi Arabia Regarding Child Abuse.

Background: Child abuse, especially when caused by the child's parents or caregivers, can be either physical, psychological, and/or sexual. Pediatric nurses should be able to identify cases of child abuse, provide appropriate care, and address the issue. Nurses' knowledge, attitudes in child abuse are essential in safeguarding the well-being and safety of those children. This study aimed to investigate pediatric nurses' knowledge and attitude about child abuse and actions taken to address such abuse. Methods: Seventy pediatric nurses working in one educational hospital in Riyadh City, Saudi Arabia participated in the study. This study followed a quantitative design. A self-administrative questionnaire was distributed to pediatric nurses. A convenience sampling was followed to include the nurses who met the criteria. An adopted validated questionnaire was used for collecting data about nurses' knowledge and attitudes regarding child abuse. The data was analyzed by SPSS with a descriptive analysis, independent t-tests or ANOVA test, and regression analysis. Results: The descriptive results indicate that participants had adequate knowledge for identifying a child as a probable victim of child abuse. All participants agreed that an important role for nurses in managing and preventing child abuse is present. The study also indicated a favorable attitude of pediatric nurses toward child abuse. Linear regression analysis showed that nurses age between 31 and 40 years were positively associated with nurses' knowledge of child abuse, nurses with fewer years of experience and nurses with experience in dealing with a victim of child abuse had a more favorable attitude. Conclusion: The study concludes that pediatric nurses have adequate knowledge and a positive attitude toward child abuse. Middle age was positively associated with nurses' knowledge of child abuse, while years of experience and experience in dealing with child abuse was inversely associated with nurses' attitude.

The immunomodulatory effects of probiotics and azithromycin in dextran sodium sulfate-induced ulcerative colitis in rats via TLR4-NF-κB and p38-MAPK pathway.

Ulcerative colitis (UC), a chronic autoimmune disease of the gut with a relapsing and remitting nature, considers a major health-care problem. DSS is a well-studied pharmacologically-induced model for UC. Toll-Like Receptor 4 (TLR4) and its close association with p-38-Mitogen-Activated Protein Kinase (p-38 MAPK) and nuclear factor kappa B (NF-κB) has important regulatory roles in inflammation and developing UC. Probiotics are gaining popularity for their potential in UC therapy. The immunomodulatory and anti-inflammatory role of azithromycin in UC remains a knowledge need. In the present rats-established UC, the therapeutic roles of oral probiotics (60 billion probiotic bacteria per kg per day) and azithromycin (40 mg per kg per day) regimens were evaluated by measuring changes in disease activity index, macroscopic damage index, oxidative stress markers, TLR4, p-38 MAPK, NF-κB signaling pathway in addition to their molecular downstream; tumor necrosis factor alpha (TNFα), interleukin (IL)1ß, IL6, IL10 and inducible nitric oxide synthase (iNOS). After individual and combination therapy with probiotics and azithromycin regimens, the histological architecture of the UC improved with restoration of intestinal tissue normal architecture. These findings were consistent with the histopathological score of colon tissues. Each separate regimen lowered the remarkable TLR4, p-38 MAPK, iNOS, NF-κB as well as TNFα, IL1ß, IL6 and MDA expressions and elevated the low IL10, glutathione and superoxide dismutase expressions in UC tissues. The combination regimen possesses the most synergistic beneficial effects in UC that, following thorough research, should be incorporated into the therapeutic approach in UC to boost the patients' quality of life.

Nano-Emulsion Based Gel for Topical Delivery of an Anti-Inflammatory Drug: In vitro and in vivo Evaluation.

Introduction: Arthritic disorder is a common disease in elderly patients and the most common cause of joint dysfunction. This study aims to design Piroxicam-loaded nanoemulsion (PXM-NE) formulations to enhance the analgesic and anti-inflammatory activity of the drug for topical use. Methods: The nanoemulsion preparations were designed based on a high-pressure homogenization technique and were characterized for particle size (PS), poly dispersity index (Pi), zeta potential (ZP), drug content, and the selected formula was investigated for its topical analgesic activity and pharmacokinetic parameters. Results: The characterizations showed that the PS was 310.20±19.84 nm, Pi was 0.15±0.02, and ZP was -15.74±1.6 mV for the selected formula. A morphology study showed that the PXM-NE droplets were spherical with a uniform size distribution. The in vitro release study showed a biphasic release pattern with a rapid release within the first 2 hours followed by a sustained release pattern. The analgesic activity for optimal formula was 1.66 times higher than the commercial gel with a double duration of analgesic activity. The Cmax was 45.73±9.95 and 28.48±6.44 ng/mL for the gel form of the selected formula and the commercial gel respectively. The relevant bioavailability of the selected formula was 2.41 higher than the commercial gel. Conclusion: The results showed good physicochemical properties, higher bioavailability, and a longer analgesic effect of PXM from nanoemulsion gel, as compared to the commercial product.

An Insight into Codon Pattern Analysis of Autophagy Genes Associated with Virus Infection.

INTRODUCTION: Apoptosis and autophagy are the two fundamental processes involved in maintaining homeostasis, and a common stimulus may initiate the processes. Autophagy has been implicated in various diseases, including viral infections. Genetic manipulations leading to altered gene expression might be a strategy to check virus infection. AIM: Determination of molecular patterns, relative synonymous codon usage, codon preference, codon bias, codon pair bias, and rare codons so that genetic manipulation of autophagy genes may be done to curb viral infection. METHODS: Using various software, algorithms, and statistical analysis, insights into codon patterns were obtained. A total of 41 autophagy genes were envisaged as they are involved in virus infection. RESULTS: The A/T and G/C ending codons are preferred by different genes. AAA-GAA and CAG-CTG codon pairs are the most abundant codon pairs. CGA, TCG, CCG, and GCG are rarely used codons. CONCLUSION: The information generated in the present study helps manipulate the gene expression level of virus infection-associated autophagy genes through gene modification tools like CRISPR. Codon deoptimization for reducing while codon pair optimization for enhancing is efficacious for HO-1 gene expression.

The Lived Experience of Middle-Aged Saudi Patients With End-Stage Chronic Renal Disease on Hemodialysis Treatment.

INTRODUCTION: More than 20,000 patients with chronic renal disease are receiving hemodialysis treatment in Saudi Arabia. Approximately, 57.4% of nurses in Saudi are expatriates. However, these nurses may not have sufficient cultural knowledge, which may affect perception of nursing care. Our purpose was to understand the lived experiences of middle-aged Saudi Arabian hemodialysis patients. METHOD: This qualitative phenomenological study was conducted in Saudi Arabia in 2021. Data were analyzed using axial coding. RESULTS: Eleven patients aged 32 to 60 years participated. Two themes and three subthemes were identified: (a) hemodialysis's negative consequences (travel restriction, social isolation, and low responsibilities toward families) and (b) level of support (family support, nurses' support, and governmental support). DISCUSSION: Hemodialysis patients find travel and social engagement difficult. Furthermore, they cannot fully meet their family responsibilities due to fatigue and long hemodialysis hours. Health care providers should consider integrating these findings to deliver optimal holistic care.

Healthcare providers screening for childhood abuse among adult patients in Saudi Arabia: A cross-sectional study.

INTRODUCTION: Childhood abuse could potentially cause negative health consequences later in life, where they influence individuals' physiological, psychological, and behavioral health. Screening for ACEs is not widely incorporated during routine primary healthcare. The information about past childhood abuse screening among adult patients is elusive. The aim of the study was to investigate healthcare providers (HCPs) practices, skills, attitudes, and perceived barriers related to past childhood abuse screening among adult patients in Saudi Arabia. DESIGN: Cross-sectional study. METHODS: Data were collected from healthcare facilities in the Riyadh and Madinah regions of Saudi Arabia using a self-reported questionnaire. RESULTS: A total of 126 HCPs completed the survey. Less than one-third of the HCPs reported routinely (usually or always) screening for childhood abuse. HCPs were more concerned that they would offend their patients by examining history of adversities. HCP practice location, the extent to which they think it is part of their responsibilities to screen for history of adversities, and their self-reported of adverse childhood experiences were significantly associated with screening practices for childhood abuse. Four perceived barriers were significantly associated with HCP screening. CONCLUSION: Screening for past adversities is vital for identifying childhood trauma among the public; therefore, we might participate in reducing childhood trauma and further controlling consequences in the future. Developing a screening form for childhood abuse or adversities and providing this form in healthcare settings are appropriate at this stage. CLINICAL RELEVANCE: Early screening for ACEs is recommended, which prioritizes health promotion and disease prevention. It is highly needed to increase HCP awareness toward childhood abuse, screening for it, and reflection on it.

Attitudes toward Nursing Profession and Fear of Infectious Diseases among Undergraduate Nursing Students: A Cross-Sectional Study.

The uncertainty surrounding the effect of infectious diseases on nursing students' attitudes toward the nursing profession worldwide exists. This study sought to examine the association between fear of infectious diseases and students' attitudes toward the nursing profession. METHODS: This quantitative descriptive cross-sectional study used a convenience sample of 477 students enrolled in nursing programs from three universities located in urban and non-urban areas in Saudi Arabia. RESULTS: The study revealed a positive attitude toward nursing and minimal fear of infectious diseases. Junior nursing students reported significantly better attitudes and preferences toward the nursing profession than senior nursing students. Students who reported positive attitudes toward the nursing profession significantly had no intension to discontinue or transfer from nursing programs, whereas students with low attitudes reported significant intention to discontinue their enrollment in the nursing programs. Students in urban universities reported higher significant fear of infectious diseases compare to non-urban. The study revealed a significant negative correlation between fear of infectious diseases and students' preference for the nursing profession. CONCLUSIONS: Nurse educators need to support senior nursing students' attitudes toward the nursing profession and reduce their fear of infectious diseases, particularly among students studying in urban areas.

The effect of low-level laser on the quality of dentin barrier after capping with bioceramic material: A histomorphometric analysis.

The study aims to investigate the quality of dentin barriers and pulp reaction to EndoSequence Root Repair Material (ERRM) combined with low-level laser application. In eight dogs, pulps were exposed via class V, half of the samples received low-level diode laser at 870 nm. Thereafter, cavities were capped with fast-set or regular-set ERRM. The specimens were processed for histomorphological and immunohistochemical examination after 2 weeks and 2 months. Dentin bridges were observed in all samples, and 87.5% were complete. The low-level laser group had significantly more reparative dentin area than the non-lased group (p < 0.05). The dentin bridges were found to have an unprecedented tubularity of 43%-89%. Tiny dentin island formation was observed within the material particles. Initial mild-to-moderate inflammatory reactions were observed, which subsided after 2 months. RUNX2 and osteocalcin staining were evident for all samples at both time intervals. Low-level laser combined with bioactive ERRM is effective in inducing reparative dentin formation.

Patients' satisfaction with nursing care quality and associated factors: A cross-section study.

AIM: This research aimed to evaluate patients' satisfaction with the nursing care quality during their hospitalization. DESIGN: Quantitative cross-sectional descriptive design. METHODS: A convenience sample of 238 patients were recruited from hospitals in two provinces in Saudi Arabia. Patient satisfaction was measured by the Arabic version of the Patients' Satisfaction with Nursing Care Quality Questionnaire (PSNCQQ-Ar). RESULTS: Significant differences were found between Saudi provinces regarding the overall quality of nursing care (M = 4.65, p < 0.001). The study revealed mean significant variations between patient satisfaction with nursing care and sociodemographic factors, including age (p = 0.002), education level (p = 0.047), marital status (p = 0.017), employment status (p = 0.038), urban vs. suburban residence (p = 0.006), length of hospitalization (p = 0.001), and accompaniment by a family member (p = 0.014). Improving patients' experience during their hospitalization requires regular examination of the quality of nursing care services. PATIENT CONTRIBUTION: This research enhances our understanding of patients satisfaction toward the quality of nursing care received during hospitalization.

Nanotechnological synergy of mangiferin and curcumin in modulating PI3K/Akt/mTOR pathway: a novel front in ovarian cancer precision therapeutics.

Background: Ovarian cancer, colloquially termed the "silent killer" among gynecological malignancies, remains elusive due to its often-asymptomatic progression and diagnostic challenges. Central to its pathogenesis is the overactive PI3K/Akt/mTOR signaling pathway, responsible for various cellular functions, from proliferation to survival. Within this context, the phytochemical compounds mangiferin (derived from Mangifera indica) and curcumin (from Curcuma longa) stand out for their potential modulatory effects. However, their inherent bioavailability challenges necessitate innovative delivery systems to maximize therapeutic benefits. Objective: This study seeks to synergize the merits of nanotechnology with the therapeutic properties of mangiferin and curcumin, aiming to bolster their efficacy against ovarian cancer. Methods: Employing specific nanotechnological principles, we engineered exosomal and liposomal nano-carriers for mangiferin and curcumin, targeting the PI3K/Akt/mTOR pathway. Molecular docking techniques mapped the interactions of these phytochemicals with key proteins in the pathway, analyzing their binding efficiencies. Furthermore, molecular dynamics simulations, spanning 100 nanoseconds, verified these interactions, with additional computational methodologies further validating our findings. The rationale for the 100 nanoseconds time span lies in its sufficiency to observe meaningful protein-ligand interactions and conformational changes. Notably, liposomal technology provided an enhancement in drug delivery by protecting these compounds from degradation, allowing controlled release, and improving cellular uptake. Results: Our computational investigations demonstrated notable binding affinities of mangiferin and curcumin: PI3K at -11.20 kcal/mol, Akt at -15.16 kcal/mol, and mTOR at -10.24 kcal/mol. The adoption of exosome/liposome-mediated delivery significantly amplified the bioavailability and cellular uptake of these nano-formulated compounds, positioning them as potential stalwarts in ovarian cancer intervention. A brief explanation of exosome/liposome-mediated delivery involves the use of these vesicles to encapsulate and transport therapeutic agents directly to the target cells, enhancing drug delivery efficiency and minimizing side effects. Conclusion: Addressing ovarian cancer's intricacies, dominated by the erratic PI3K/Akt/mTOR signaling, mandates innovative therapeutic strategies. Our pioneering approach converges nanotechnological liposomal delivery with mangiferin and curcumin's natural efficacies. This confluence, validated by computational insights, heralds a paradigm shift in ovarian cancer treatment. As our findings underscore the collaborative potential of these phytochemicals, it beckons further exploration in translational studies and clinical applications, ensuring the best intersection of nature and technology for therapeutic advantage.

Assessment of the Proximity of the Inferior Alveolar Canal with the Mandibular Root Apices and Cortical Plates-A Retrospective Cone Beam Computed Tomographic Analysis.

Various endodontic interventions often lead to iatrogenic damage to the inferior alveolar nerve present in the inferior alveolar canal (IAC). The purpose of the present study was to analyze the relationships of IAC with the root apices of mandibular teeth and with the mandibular cortical plates. MATERIALS: 116 cone beam computed tomography (CBCT) scans were examined and the shortest distance of IAC with the root apices of mandibular canines, premolars and molars, and with cortical plates was analyzed. The data were statistically analyzed using SPSS. RESULTS: The shortest mean distance between IAC and lingual cortical plate (LCP) was found in the third molar area, and between IAC and buccal cortical plate (BCP) in the second premolar area. A high incidence of 60% direct communication (DC) was present in mandibular second molars; 38% in mandibular third molars; 13% in mandibular second premolars; 12% in mandibular first molars; and 1% in mandibular first premolars. CONCLUSION: Anteriorly, IAC was found to be significantly present in close approximation to the roots of mandibular canines. Posteriorly, IAC was found to be in significant proximity to the distal roots of mandibular second molars.
