Awareness of sickle cell disease among nursing undergraduates in Farasan: Its interference with malaria.

Aim: The present study was conducted to generate data on awareness and incidence of sickle cell disease (SCD) and also to adduce the widespread myths peddled about SCD. Materials and Methods: Students studying in the Department of Nursing were recruited. A pretested, self-administered sickle cell assessment questionnaire was distributed electronically through WhatsApp group to collect necessary data. Participants were screened for malaria by thin blood smear analyses, and their hemoglobin (Hb) contents (g/dL) were determined by Sahli's haemoglobinometer. Statistical analyses were done using Origin (version 8.1, USA). A reliability study was performed for the validity of questionnaire data. Results: Study participants had significantly high awareness regarding SCDs (89.9%, P < 0.001). Most participants (96.3%) were aware about government policy regarding premarital screening for genetic disorders and replied that the government has strict health policies backed by equally robust laboratory diagnostics. Moreover, none of the participants had SCDs, although their parents had a consanguineous marriage. Thin blood smear analyses of participants did not reveal any cases of Plasmodium falciparum. However, significant percentages (33.1%) were found to be anemic, probably due to their dietary habits and lifestyles, as has been reflected by questionnaire analyses. Furthermore, a very less number of students had knowledge about genetic variations that might occur in malaria-endemic regions after long exposure to offer protection from malaria. Knowledge about management practices was also lacking among study participants (29%). Conclusion: This research points to the necessity that the nursing study plan should focus on providing specific training on management skills and preventive measures for SCDs, which is of paramount importance.

Hexaconazole exposure may lead to Parkinson via disrupting glucocerebrosidase and parkin: molecular interaction, dynamics, MMPBSA and DFT based in-silico predictive toxicology.

Hexaconazole is a known fungicide for agricultural purposes. It has bioaccumulation ability which makes it important for its toxicological characterization. There are various neurological impacts of pollutants on human health. Therefore, in this study, we have done predictive analyses of the interaction mechanism of hexaconazole by molecular interaction analysis, molecular dynamics simulation, and Poisson-Boltzmann surface area (MM-PBSA) to assess hexaconazole's potency to disrupt the homeostasis of glucocerebrosidase (-7.9 kcal/mol) and parkin (-5.67 kcal/mol) proteins which have significant roles in the manifestation of Parkinson disease. The findings reveal that hexaconazole has the potency to form stable interactions with glucocerebrosidase and parkin. This research provides a molecular and atomic-level understanding of how hexaconazole exposure may disrupt the homeostasis of glucocerebrosidase and parkin. The root mean square deviation (RMSD), root mean square fluctuation (RMSF), radius of gyration, and hydrogen bonding exhibited the potent molecular interactions of hexaconazole, which may lead to neurological manifestations such as Parkinson disease.

Serotonin Receptor agonist and Risk of Paresthesia in Migraine Patients: A Dose-Response Model-Based (Network) Meta-Analysis.

Background: Migraine may be an important factor for paresthesia in the limbs, especially in the upper limbs. In several patients, paresthesia is responsible for a low quality of life. Treatment with the serotonin agonist may be a triggering factor for paresthesia in certain patients. Various serotonin receptor agonists are available for migraine treatment. We performed a meta-analysis of updated clinical trials of the serotonin agonist to figure out the risk of paresthesia. Methods: PubMed, Embase, and Cochrane Library databases were searched for clinical trials that evaluated the serotonin agonist for migraine treatment versus placebo. The main outcomes were to perform dose-response model-based network meta-analysis of different serotonin agonists and to compute the relative risk for paresthesia. In addition, probability of paresthesia among various treatments was estimated by the Surface Under the Cumulative Ranking (SUCRA) method. The R 4.30 and Rev Man 5.3 softwares were used to perform meta-analysis. Results: A total of 30 placebo-controlled clinical trials (29,154 subjects) were included in the study to perform dose-response model-based network meta-analysis to explore the risk of paresthesia with different serotonin agonists versus placebo. The drugs Topiramate 200 mg, Lasmiditan 400 mg, and Zolmitriptan 10 mg showed higher relative risks for paraesthesia as 2.71, 2.2, and 2.42, respectively. However, the SUCRA probabilities of paresthesia for each treatment in the network were higher for Lasmiditan. Conclusions: This meta-analysis of reported placebo-controlled clinical trials suggests that the SUCRA probabilities for the manifestation of paresthesia are higher with Lasmiditan. The relative risk of paresthesia is higher with the use of Topiramate 200 mg, Lasmiditan 400 mg, and Zolmitriptan 10 mg. In addition, Lasmiditan exhibited a gradual dose-response of relative risk for the manifestation of paresthesia.

Multi-Epitope-Based Vaccine Candidate for Monkeypox: An In Silico Approach.

Currently, there are limited treatment options available for the monkeypox disease. We used a computational strategy to design a specific antigenic vaccine against pathogens. After using various immunoinformatic tools and filters, cytotoxic T-cell lymphocyte (CTL)-, helper T-cell lymphocyte (HTL)-, and interferon gamma (IFN-γ)-inducing epitopes, which comprised the vaccine, in addition to other parameters, such as antigenic and allergic profiles, were assessed to confirm the safety of the vaccine. However, vaccine interaction and stability with Toll-like receptors (TLRs) were assessed by dynamic simulation methods, and it was found that the constructed vaccine was stable. In addition, C-IMMSIM tools were used to determine the immune-response-triggering capabilities of the vaccine. These immunoinformatic findings reveal that constructed vaccine candidates may be capable of triggering an efficient immune response for monkeypox viral infections. However, experimental evaluation is required to verify the safety and immunogenic profile of constructed vaccines.

Sunscreen Ingredient Octocrylene's Potency to Disrupt Vitamin D Synthesis.

Octocrylene is a widely used ingredient in sunscreen products, and it has been observed that the use of sunscreen has been increasing over the last few decades. In this paper, we investigated the way in which sunscreen's ingredient octocrylene may disrupt normal vitamin D synthesis pathway, resulting in an imbalance in vitamin D levels in the body. The key techniques used for this insilico investigation were molecular docking, molecular dynamic (MD) simulation, and MMPBSA-based assessment. Vitamin D abnormalities have become very common in human health. Unknown exposure to chemicals may be one of the important risk factors. In molecular docking analysis, octocrylene exhibited a binding energy of -11.52 kcal/mol with vitamin D binding protein (1KXP) and -11.71 for the calcitriol native ligand. Octocrylene had a binding potency of -11.152 kcal/mol with the vitamin D receptor (1DB1), and calcitriol had a binding potency of -8.73 kcal/mol. In addition, octocrylene has shown binding energy of -8.96 kcal/mol with CYP2R1, and the calcitriol binding energy was -10.36 kcal/mol. Regarding stability, the root-mean-square deviation (RMSD), the root-mean-square fluctuation (RMSF), the radius of gyration, hydrogen bonding, and the solvent-accessible surface area (SASA) exhibited that octocrylene has a stable binding pattern similar to calcitriol. These findings revealed that incessant exposure to octocrylene may disrupt normal vitamin D synthesis.

Haemoglobin status to determine nutritional anaemia and its association with breakfast skipping and BMI among nursing undergraduates of Farasan Island, KSA.

The present study was conducted to determine nutritional anaemia using haemoglobin levels of female nursing undergraduates studying at Farasan Island with the purpose to intervene at a point, before the potential problems become serious later in life. In total, 130 apparently healthy, female students of Department of Nursing were recruited by a random sampling method to collect information on socio-demographic, lifestyle and anthropogenic characteristics, and dietary habits including breakfast skipping. Haemoglobin content was estimated using Sahli's Haemoglobinometer and observations were interpreted as per WHO's criteria for anaemia. Body mass index (BMI) was recorded using a digital weighing machine. Correlation between haemoglobin concentration, breakfast skipping and body mass index of study participants was assessed by Pearson's correlation. Data analyses were done using Origin software. Overall, 51⋅6 % (n = 67) students were all together anaemic with 28⋅5 % (n = 37) had mild anaemia, 15⋅4 % (n = 20) moderate and 7⋅69 % (n = 10) had severe anaemia. Of these, 20⋅8 % (n = 27) were underweight, 63⋅8 % (n = 83) normal weight and 15⋅4 % (n = 20) were above normal weight (over weight and obese). The Hb content showed a positive correlation with the BMI and exhibited an increasing trend with increase in the BMI among study participants (P < 0⋅05). Questionnaire analyses revealed that the majority (96⋅9 %, n = 126) of students were taking junk food as bulk of their meal. A strong negative correlation was recorded between Hb contents and breakfast skipping tendencies (r = -0⋅987, P < 0⋅05). Findings of the present study are of high significance for public health professionals and educators to prioritise actions that could motivate these future nurses to adapt healthy lifestyles to strategically combat nutritional anaemia.

Morusflavone, a New Therapeutic Candidate for Prostate Cancer by CYP17A1 Inhibition: Exhibited by Molecular Docking and Dynamics Simulation.

Morusflavone, a flavonoid from Morus alba L., was evaluated for its interactive ability and stability with CYP17A1, in comparison with abiraterone, which is a Food and Drug Administration (FDA)-approved CYP17A1 inhibitor. CYP17A1 inhibition is an important therapeutic target for prostate cancer. The CHAMM36 force field was used to perform molecular dynamics (MD) simulations in this study. The results show that Morusflavone has significant interactive ability and stability for CYP17A1, in comparison with abiraterone. The final interaction energies for the Morusflavone-CYP17A1 and abiraterone-CYP17A1 complexes were -246.252 KJ/mol and -207.86 KJ/mol, respectively. Since there are only limited therapeutic agents available, such as abiraterone, galeterone, and seviteronel, which are being developed for prostate cancer, information on any potent natural anticancer compounds, such as vinca alkaloids, for prostate cancer treatment is limited. The results of this study show that CYP17A1 inhibition by Morusflavone could be an important therapeutic target for prostate cancer. Further preclinical and clinical evaluations of the lead compound Morusflavone are required to evaluate whether it can serve as a potential inhibitor of CYP17A1, which will be a new hope for prostate cancer treatment.

Molecular docking and dynamics simulation to screen interactive potency and stability of fungicide tebuconazole with thyroid and sex hormone-binding globulin: Implications of endocrine and reproductive interruptions.

Tebuconazole is a widely used fungicide in agriculture, and it may easily enter in the human food chain. In addition, tebuconzaol skin permeation coefficient (Log Kp) is -5.55 cm/s and it does not violate Lipinski's rule. It may mimic as a ligand for various endocrine and reproductive receptor leading to toxicological response or disease manifestation. We studied interactive potential of tebuconazole with thyroid and sex hormone-binding globulin. The main methods for this in silico analyses are molecular docking and molecular dynamic (MD) simulation. This paper explores how agriculture fungicide tebuconzaol exposure can be a risk for endocrine and reprotoxicity due to its stable interactive potency with thyroid and sex hormone-binding globulin (2CEO and 1D2S). Thyroid impairment is one of the most common endocrine issues in human health. In molecular docking analyses, tebuconazole exhibited binding potency of -6.28 kcal/mol with 2CEO compared to its native ligand thyroxin and inhibitor propylthiouracil which had the binding potency of -9.9 and -4.49 kcal/mol, respectively. The binding score of tebuconzaol with 1D2S was found to be -7.54 kcal/mol compared to native ligand dihydrotestosteron and inhibitor aminoglutethimide which exhibited the binding score of -6.84 and -11.41 kcal/mol, respectively. Therefore, each complex was subjected to MD simulation for comparative assessment of physical movement. The root mean square deviation (RMSD), root mean square fluctuation (RMSF), Radius of Gyration and hydrogen bonding exhibited that fluconazole had stable binding pattern with 2CEO and 1D2S which was almost similar to native ligand and its inhibitor. Study revealed that tebuconazole may lead to potent endocrine and reproductive disruptions.
