Contrast-induced nephropathy (CIN) is a serious condition that may develop in patients undergoing diagnostic radiologic procedures. Several treatments have been assessed to prevent CIN development. This study aims to assess the efficacy and safety of vitamin E in the prevention of CIN compared to intravenous (IV) saline hydration. The literature search included MEDLINE/PubMed, Cochrane Central Register of Controlled Trials, the Web of Science, ProQuest, and Scopus for articles published until May 11, 2024, without language or time limits. The outcomes included the incidence of CIN, new-onset dialysis, and death (primary), as well as the change in serum creatinine and glomerular filtration rate (GFR) (secondary). Numerical and dichotomous outcomes were presented as standardized mean difference (SMD) and risk ratio (RR), respectively, with 95% confidence intervals (CI). Six clinical trials were included. Vitamin E was administered orally in varying doses, but one study used IV infusion. Vitamin E decreased the risk of developing CIN by 59% (n=5; pooled RR: 0.41; 95% CI: 0.25, 0.65; P<0.001) compared to IV hydration. None of the patients required renal replacement therapy. One patient on vitamin E died due to the occurrence of acute coronary syndrome. Vitamin E is a promising effective prophylaxis against CIN. However, the number of included studies and their sample sizes are small. The studies showed several limitations. There is a need for further high-quality clinical trials to ascertain the effectiveness of vitamin E compared to IV hydration and to compare vitamin E to other therapies, such as N-acetyl cysteine., Competing Interests: Conflicts of interest: In compliance with the ICMJE uniform disclosure form, all authors declare the following: Payment/services info: All authors have declared that no financial support was received from any organization for the submitted work.

The efficient degradation of organic pollutants in diverse environmental matrices can be achieved through the synergistic application of piezo-catalysis and photocatalysis. The focus of this study is on understanding the fundamental principles and mechanisms that govern the collaborative action of piezoelectric and photocatalytic materials. Piezoelectric nanomaterials, under mechanical stress, generate piezo-potential, which, when coupled with photocatalysts, enhances the generation and separation of charge carriers. The resulting cascade of redox reactions promotes the degradation of a wide spectrum of organic pollutants. The comprehensive investigation involves a variety of experimental techniques, including advanced spectroscopy and microscopy, to elucidate the intricate interplay between mechanical and photoinduced processes. The influence of key parameters, such as material composition, morphology, and external stimuli on the catalytic performance, is systematically explored. This study contributes to the increasing knowledge of environmental remediation and lays the foundation for the development of advanced technologies using piezo and photocatalysis for sustainable pollutant removal., (© 2024 John Wiley & Sons Ltd.)

Immunoglobulin E (IgE)-mediated allergy, which affects more than 30% of the population, is the most prevalent hypersensitivity illness. In an atopic individual, even a small amount of allergen exposure can cause IgE antibodies to be produced. Due to the engagement of receptors that are highly selective for IgE, even tiny amounts of allergens can induce massive inflammation. This study focuses on the exploration and characterization of the allergen potential of Olea europaea allergen (Ole e 9) affecting the population in Saudi Arabia. A systematic computational approach was performed to identify potential epitopes of allergens and complementary determining regions of IgE. In support, physiochemical characterization and secondary structure analysis unravel the structural conformations of allergens and active sites. Epitope prediction uses a pool of computational algorithms to identify plausible epitopes. Furthermore, the vaccine construct was assessed for its binding efficiency using molecular docking and molecular dynamics simulation studies, which led to strong and stable interactions. This is because IgE is known to play a role in allergic responses, which facilitate host cell activation for an immune response. Overall, the immunoinformatics analysis advocates that the proposed vaccine candidate is safe and immunogenic and therefore can be pushed as a lead for in vitro and in vivo investigations.Communicated by Ramaswamy H.

Objective: Both diabetes mellitus (DM) and thyroid dysfunction (TD) are endocrinopathies that are frequently inclined to coexist in patients. Most studies avoid explicitly supporting or opposing testing thyroid function for diabetic patients as a baseline. The association between hypothyroidism and diabetes is considerable when assessing thyroid functions in diabetic individuals based on clinical suspicion. Therefore, this study aimed to assess the relationship between thyroid dysfunction and its manifestations in DM patients in the Kingdom of Saudi Arabia., Subjects and Methods: The study included 301 DM subjects. A questionnaire divided into two sections was administered to all participants. The first section involved questions about diabetes control, monitoring, and disease severity. The second section included questions about thyroid disease and the 14-item Hypothyroidism Clinical Prediction (HCP) score we created for our research. The HCP score was obtained by summing up all discrete scores for different symptoms of hypothyroidism. ROC curve analysis was used to assess the predicted hypothyroidism cases based on the most precise cut-off point for the HCP overall score (highest sensitivity and specificity). HCP discriminant ability for detecting hypothyroid cases was assessed considering the Area Under the Curve (AUC) as a measurement., Results: Almost 53 (17.6%) diabetes mellitus subjects were previously diagnosed with hypothyroidism. Comparatively, regarding the given cut-off point, the total number of predicted hypothyroidism cases using the HCP score was 149 (49.5%). The most reported symptoms included tiredness (75%), followed by irritability (72%), and difficulty in losing weight (65%). Hypothyroidism was detected/predicted among 60.1% of female diabetics vs. 44.2% of males with recorded statistical significance (p=.006)., Conclusions: This study further proves a significant association between diabetes and hypothyroidism in Saudi Arabia. We recommend periodic screening for thyroid dysfunction in the diabetic population in specific cases; since some patients with diabetes are more likely to have hypothyroidism based on their clinical presentation.

Respiratory allergies have become a major public health concern and affect one-third of the world's population. Several factors like environmental changes, industrialization, and immunologic interactions are reported to contribute to allergic respiratory diseases. Immunological reactions because of mosquito bite (allergic proteins) have been reported to have a high contribution to IgE-mediated allergic airway disease but they are largely ignored. In this study, we aim to predict the potential allergens (proteins) from Aedes aegypti that might play a role in the reactions of IgE-mediated allergic airway diseases. The allergens are identified from an extensive literature search and the 3D structures were prepared using the SwissDock server. Computational studies were performed to identify the potential allergens that might be responsible for IgE-mediated allergies. Our docking and molecular dynamics (MD) simulation results suggest that ADE-3, an allergen from Aedes aegypti, has the highest docking score and is predicted to be responsible for IgE-mediated allergic reaction(s). Overall, this study highlights the importance of immunoinformatics, and the obtained information can be used for designing prophylactic peptide vaccine candidates and inhibitors for controlling IgE-mediated inflammations.Communicated by Ramaswamy H.

Currently, novel technologies are highly prerequisite as an outstanding approach in the field of photocatalytic water splitting (PWS). Previous research has shown that copolymerization technology could improve the photocatalytic performance of pristine carbon nitride (CN) more efficiently. As this technology further allows the charge carrier recombination constraints, due to novel monomer-incorporated highly abundant surface-active sites of metals in polymeric carbon nitride-based heterojunction. However, in present study, a novel previously unexplored thiophenedicarboxaldehyde (TAL) conjugated, strontium-titanium (SrTiO 3 ) induced and CN based heterojunction, i.e., SrTiO 3 /CN-TAL 10.0 , was prepared for solar-driven hydrogen evolution reaction (HER). This heterojunction effectively enables the proficient isolation of photoinduced charge carriers and enhanced the charge transport over the surface junction, by enhancing the optical absorption range and average lifetime of photogenerated charges. The incorporation of TAL within the structure of CN via copolymerization highly increases the photocatalytic activity, as well as maintaining its photostability performance. The SrTiO 3 concentration and the proportion of TAL among CN can be precisely controlled to provide the optimal photocatalytic efficiency with a maximum HER of 285.9 µmol/h under visible light (λ = 420 nm). Based on these results, our optical analysis shows that coupling of SrTiO 3 and TAL monomer in the structure of CN considerably reduce the band gap of superior sample from (3.42 to 2.66 eV), thereby, signifying the outstanding photocatalytic performance of SrTiO 3 /CN-TAL 10.0 . Thus, this study provide a new guideline in order to develop the multidimensional photocatalysts with proper functioning for sustainable energy conversion and production., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2023 Elsevier Inc.

SARS-CoV-2 has caused the most devastating pandemic of all time in recent human history. However, there is a serious paucity of high-quality data on aggravating factors and mechanisms of co-infection. This study aimed to identify the trending patterns of bacterial co-infections and types and associated outcomes in three phases of the pandemic. Using quality hospital data, we have investigated the SARS-CoV-2 fatality rates, profiles, and types of bacterial co-infections before, during, and after COVID-19 vaccination. Out of 389 isolates used in different aspects, 298 were examined before and during the pandemic ( n = 149 before, n = 149 during). In this group, death rates were 32% during compared to only 7.4% before the pandemic with significant association ( p -value = 0.000000075). However, the death rate was 34% in co-infected ( n = 170) compared to non-co-infected patients ( n = 128), indicating a highly significant value ( p -value = 0.00000000000088). However, analysis of patients without other serious respiratory problems ( n = 28) indicated that among the remaining 270 patients, death occurred in 30% of co-infected patients ( n = 150) and only 0.8% of non-co-infected ( n = 120) with a high significant p -value = 0.00000000076. The trending patterns of co-infections before, during, and after vaccination showed a significant decline in Staphylococcus aureus with concomitant peaks in Gram negatives n = 149 before/ n = 149 during, including Klebsiella pneumonian = 11/49 before/during, E. coli n = 10/24, A. baumannii n = 8/25, Ps. aeruginosa n = 5/16, and S. aureus 13/1. Nevertheless, in the post-vaccination phase ( n = 91), gender-specific co-infections were examined for potential differences in susceptibility. Methicillin-resistant S. aureus dominated both genders followed by E. coli in males and females, with the latter gender showing higher rates of isolations in both species. Klebsiella pneumoniae declined to third place in male patients. The drastic decline in K. pneumoniae and Gram negatives post-vaccination strongly implied a potential co-protection in vaccines. Future analysis would gain more insights into molecular mimicry.

Acute respiratory distress syndrome (ARDS) is one of the major problems in COVID-19 that is not well understood. ARDS is usually complicated by co-infections in hospitals. Although ARDS is inherited by Europeans and Africans, this is not clear for those from the Middle East. There are severe limitations in correlations made between COVID-19, ARDS, co-infectome, and patient demographics. We investigated 298 patients for associations of ARDS, coinfections, and patient demographics on COVID-19 patients' outcomes. Of the 149 patients examined for ARDS during COVID-19, 16 had an incidence with a higher case fatality rate (CFR) of 75.0% compared to those without ARDS (27.0%) ( p value = 0.0001). The co-infectome association showed a CFR of 31.3% in co-infected patients; meanwhile, only 4.8% of those without co-infections ( p value = 0.01) died. The major bacteria were Acinetobacter baumannii and Escherichia coli , either alone or in a mixed infection with Klebsiella pneumoniae . Kaplan-Meier survival analysis of COVID-19 patients with and without ARDS revealed a significant difference in the survival time of patients with ARDS (58.8 +/- 2.7 days) and without ARDS (41.9 +/- 1.8 days) ( p value = 0.0002). These findings prove that increased hospital time was risky for co-infectome-induced SDRS later on. This also explained that while empiric therapy and lethal ventilations delayed the mortality in 75% of patients, they potentially did not help those without co-infection or ARDS who stayed for shorter times. In addition, the age of patients ( n = 298) was significantly associated with ARDS (72.9 +/- 8.9) compared to those without it (56.2 +/- 15.1) and was irrespective of gender. However, there were no significant differences neither in the age of admitted patients before COVID-19 (58.5 +/- 15.3) and during COVID-19 (57.2 +/- 15.5) nor in the gender and COVID-19 fatality ( p value 0.546). Thus, Gram-negative co-infectome potentially induced fatal ARDS, aggravating the COVID-19 outcome. These findings are important for the specific differential diagnosis of patients with and without ARDS and co-infections. Future vertical investigations on mechanisms of Gram-negative-induced ARDS are imperative since hypervirulent strains are rapidly circulating. This study was limited as it was a single-center study confined to Ha'il hospitals; a large-scale investigation in major national hospitals would gain more insights.

Objective: To compare high-para and low-para women with respect to haematological findings, determinants, and consequences secondary to anaemia., Study Design: Descriptive cohort study. Place and Duration of the Study: Maternity and Child Hospital, Hail, Saudi Arabia and Specialist Care Hospital (private), Islamabad, Pakistan, from April 2022 to April 2023., Methodology: The study population comprised of pregnant women in the last trimester, with the exception of those women who had more than one fetus and history of haematological disease. Purposive non-probability sampling technique was adopted. Hospital data were retrieved retrospectively for the past obstetrical, contraception usage, and supplement history. Blood parameters, type of delivery, and maternofetal complications were noted down. For qualitative-variable and quantitative-variable comparisons, Chi-square test and t-test were applied, respectively. Significance level was kept at p ≤0.05., Results: The frequency of severe anaemia in high-para was 52%. High parity and anaemia had a significant dose-response relationship (p <0.05). There was a significant difference (p <0.05) in blood parameters between high-para and low-para groups. Main determinants identified for anaemia were lack of intake of iron-rich food (36%) followed by inadequate intake of oral iron (25%). Preterm birth (68%) and post-partum haemorrhage (96%) were significantly associated (p <0.05) with high parity. There was a significantly high proportion (83%) of high-para women with more than 3 cesarean deliveries and admissions in ICU., Conclusion: High parity and anaemia had a significant dose-response relationship. High parity was the main determinant of maternal and fetal admissions in ICU., Key Words: Parity, Comparison, Maternal anaemia, Haematological findings, Diet, Contraception, Cost-effective.

Metal-organic frameworks (MOFs), a material known for its multifunctionality, chemical stability, and high surface area, are now commonly utilized as an adsorbent for water treatment. The MOF (MIL-88(Fe)-NH 2 ) was synthesized and used to remove the commonly used toxic herbicide 2,4-dichlorophenoxyacetic acid (2,4-D) from water. The MIL-88(Fe)-NH 2 MOF was fully characterized using multiple techniques. A systematic investigation was conducted to evaluate the key parameters that impact the adsorption process, which include coexisting anions, adsorbent dosage, and solution pH. The adsorption isotherm was fitted using the Langmuir model, while the kinetics were fitted using pseudo-second-order. The adsorption process was both chemisorption and endothermic. The capacity for adsorption increased with rising temperatures. The MIL-88(Fe)-NH 2 adsorbent has a maximum adsorption capacity of 345.25 mg g -1 for removing 2,4-D, significantly higher than previous adsorbents used for this purpose. The adsorption mechanism could be ascribed to hydrogen bonding, pore filling, π-π conjugations between the 2,4-D molecules and the MIL-88(Fe)-NH 2 adsorbent, and electrostatic interactions. Furthermore, the adsorption capacity of MIL-88(Fe)-NH 2 adsorbent showed only a slight decrease after five successive recycles, and it could be easily regenerated through solvent washing. When used in environmental water samples, especially those containing electronic wastes, the MIL-88(Fe)-NH 2 adsorbent demonstrated satisfactory adsorption capacity and reusability. The MIL-88(Fe)-NH 2 adsorbent is more practical and reusable and has better adsorption capacity and shorter equilibrium time compared to previously reported adsorbents., Competing Interests: The authors declare no competing financial interest., (© 2023 The Authors.

Background Early-stage prostate cancer may not show any signs. Digital rectal examination and the prostate-specific antigen test are frequently used in the screening for prostate cancer. The objective of this research is to assess the knowledge and awareness of screening prostate cancer among males in Tabuk, Saudi Arabia. Methodology A cross-sectional study was performed among Saudi males in Tabuk City. A structured interviewing technique based on a questionnaire was used based on the objectives and research questions. Data were collected by well-trained data collectors from the general population in Tabuk City who were randomly chosen in proportion to the city's population density. A multivariate logistic regression analysis was done to evaluate the variables related to knowledge and awareness in this study. Results This questionnaire was completed by a total of 417 male participants. In the studied group, 86.8% of participants had heard about prostate cancer through friends (59%), TV/radio/newspaper (53.24%), and other health services (41.49%). In addition, around 67.6% of participants knew about the prostate cancer screening test. In addition, 32.4% of participants had no prior knowledge of prostate cancer or a screening test. Conclusions There was a good level of awareness and attitude toward screening methods for prostate cancer (54.7%). Aside from having good knowledge regarding prostate cancer symptoms among males in Tabuk City, all participants with regard to demographic distribution showed a significant level of good knowledge and awareness of screening prostate cancer methods and the necessity of performing regular prostate examinations., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2023, Shaqran et al.)

Multidisciplinary research efforts on potential COVID-19 vaccine and therapeutic candidates have increased since the pandemic outbreak of SARS-CoV-2 in 2019. This search has become imperative due to the increasing emergences and limited widely available medicines. The presence of bioactive anti-SARS-CoV-2 molecules was examined from various plant sources. Among them is a group of proteins called lectins that can bind carbohydrate moieties. In this article, we present ten novel, chitin-specific Hevein-like lectins that were derived from Selaginella moellendorffii v1.0's genome. The capacity of these lectin homologs to bind with the spike protein of SARS-CoV-2 was examined. Using the HDOCK server, 3D-modeled Hevein-domains were docked to the spike protein's receptor binding domain (RBD). The Smo446851, Smo125663, and Smo99732 interacted with Asn343-located complex N -glycan and RBD residues, respectively, with binding free energies of -17.5, -13.0, and -26.5 Kcal/mol. The molecular dynamics simulation using Desmond and the normal-state analyses via torsional coordinate association for the Smo99732-RBD complex using iMODS is characterized by overall higher stability and minimum deformity than the other lectin complexes. The three lectins interacting with carbohydrates were docked against five individual mutations that frequently occur in major SARS-CoV-2 variants. These were in the spike protein's receptor-binding motif (RBM), while Smo125663 and Smo99732 only interacted with the spike glycoprotein in a protein-protein manner. The precursors for the Hevein-like homologs underwent additional characterization, and their expressional profile in different tissues was studied. These in silico findings offered potential lectin candidates targeting key N -glycan sites crucial to the virus's virulence and infection.

Frequent washing of textiles poses a serious hazard to the ecosystem, owing to the discharge of harmful effluents and the release of microfibers. On one side, the harmful effluents from detergents are endangering marine biota, while on the other end, microplastics are observed even in breastfeeding milk. This work proposes the development of sunlight-driven cleaning and antibacterial comfort fabrics by immobilizing functionalized Zn-doped TiO 2 nanoparticles. The research was implemented to limit the use of various detergents and chemicals for stain removal. A facile sol-gel method has opted for the fabrication of pristine and Zn-doped TiO 2 nanoparticles at three different mole percentages of Zn. The nanoparticles were successfully functionalized and immobilized on cotton fabric using silane coupling agents via pad-dry-cure treatment. As-obtained fabrics were characterized by their surface morphologies, availability of chemical functionalities, and crystallinity. The sunlight-assisted degradation potential of as-functionalized fabrics was evaluated against selected pollutants (eight commercial dyes). The 95-98% degradation of dyes from the functionalized fabric surface was achieved within 3 h of sunlight exposure, estimated by color strength analysis with an equivalent exposition of bactericidal activities. The treated fabrics also preserved their comfort and mechanical properties. The radical trapping experiment was performed to confirm the key radicals responsible for dye degradation, and h + ions were found to be the most influencing species. The reaction pathway followed the first order kinetic model with rate constant values of 0.0087 min -1 and 0.0131 min -1 for MB and MO dyes, respectively.

Graphitic carbon nitride (g-C 3 N 4 ) has gained tremendous interest in the sector of power transformation and retention, because of its distinctive stacked composition, adjustable electronic structure, metal-free feature, superior thermodynamic durability, and simple availability. Furthermore, the restricted illumination and extensive recombination of photoexcitation electrons have inhibited the photocatalytic performance of pure g-C 3 N 4 . The dimensions of g-C 3 N 4 may impact the field of electronics confinement; as a consequence, g-C 3 N 4 with varying dimensions shows unique features, making it appropriate for a number of fascinating uses. Even if there are several evaluations emphasizing on the fabrication methods and deployments of g-C 3 N 4 , there is certainly an insufficiency of a full overview, that exhaustively depicts the synthesis and composition of diverse aspects of g-C 3 N 4 . Consequently, from the standpoint of numerical simulations and experimentation, several legitimate methodologies were employed to deliberately develop the photocatalyst and improve the optimal result, including elements loading, defects designing, morphological adjustment, and semiconductors interfacing. Herein, this evaluation initially discusses different dimensions, the physicochemical features, modifications and interfaces design development of g-C 3 N 4 . Emphasis is given to the practical design and development of g-C 3 N 4 for the various power transformation and inventory applications, such as photocatalytic H 2 evolution, photoreduction of CO 2 source, electrocatalytic H 2 evolution, O 2 evolution, O 2 reduction, alkali-metal battery cells, lithium-ion batteries, lithium-sulfur batteries, and metal-air batteries. Ultimately, the current challenges and potential of g-C 3 N 4 for fuel transformation and retention activities are explored., (© 2023 The Chemical Society of Japan & Wiley-VCH GmbH.)

In the context of the global increase in the rate of cesarean deliveries, with an associated higher morbidity and mortality, this study aimed to investigate the role of maternal age and parity in the cesarean section rate among women in the Hail Region of Saudi Arabia. This retrospective cohort study used data collected from the labor ward of the Maternity and Child Health Hospital, Hail, over a period of 8 months, forming a cohort of 500 women. Women were categorized into four different parity classes. The results revealed that there was no significant relationship between cesarean deliveries and maternal age ( p -value, 0.07). There was no significant difference in the mode of delivery between the study's parity cohort group. A significant increase in cesarean deliveries was noticed among obese women with a BMI between 35-39.9 (52.14%). This increase was even greater among those with a BMI above 40 (63.83%). Fetal distress, malpresentation and abruptio placenta were the most significant indications for CS among all age groups ( p -value 0.000, 0.021, and 0.048, respectively). Conclusions: The number of cesarean deliveries has no association with parity or age. However, there was a statistically significant association with BMI, a perineal tear after previous vaginal delivery, and a history of diabetes mellitus and gestational diabetes. The most reported reasons for CS were fetal distress, malpresentation, and abruptio placenta among all age groups.

The lethal pathogenic severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection has caused the COVID-19 pandemic, posing serious risks to people. The clove-like spike (S) protein that distinguishes coronaviruses from other viruses is important for viral pathogenicity, evolution, and transmission. The investigation of the unique structural mutations of the SARS-CoV-2 spike protein among 34 Asian countries, as well as the resulting phylogenetic relationship, provided critical information in understanding the pathogenesis. This can be utilized for the discovery of possible treatments and vaccine development. The current study analyzed and depicted phylogenetic and evolutionary models useful for understanding SARS-CoV-2 human-human transmission dynamics in Asian regions with shared land borders. Further, integrated bioinformatics analysis was performed to predict the pathogenic potential and stability of 53 mutational positions among 34 coronavirus strains. Mutations at positions N969K, D614G and S884F have deleterious effects on protein function. These findings are crucial because the Asian mutations could potentially provide a vaccine candidate with co-protection against all SARS-CoV-2 strains. This region is vulnerable because of the high population density and the volume of domestic and international travel for business and tourism. These discoveries would also aid in the development of plans for governments and the general populace to implement all required biocontainment protocols common to all countries., Competing Interests: The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (© 2023 The Authors.)

Temperature-driven colorful switching inks have been an interesting security encoding method to improve the anticounterfeiting properties of commercially available merchandise. Recently, thermochromic inks have faced many disadvantages, such as low efficiency, high cost, and low durability. In the current study, we developed self-healable ink from poly(2-acrylamido-2-methyl-1-propanesulfonic acid) (PAMPSA) integrated with the anthocyanidin(ACY)-based red-cabbage extract in the presence of ferrous sulfate for authentication purposes. Self-healable inks have been able to guarantee durability and thermal stability. Environmentally friendly, ACY-based chromophore was extracted from Brassica oleracea L. var. Capitata (red-cabbage) to serve as a spectroscopic probe immobilized into PAMPSA. The prepared self-healable nanocomposite ink (PAMPSA-ACY) displayed temperature-induced chromism with high reversibility and thermal stability. Different self-healable nanocomposite inks of thermochromic features were prepared employing different ratios of the ACY-based red-cabbage extract. As described by Commission Internationale de L'éclairage Lab coordinates, homogeneous films were stamped on the paper surface to show a purple color (631 nm) able to switch color into red (458 nm) with the increase in temperature from 25 to 65 °C, respectively. Transmission electron microscopy, infrared spectra (FT-IR), energy-dispersive X-ray, and scanning electron microscopy were utilized to inspect the morphological behavior and chemical compositions of thermochromic prints. Both mechanical and rheological properties of ink-printed paper substrates and ink solution were also investigated. Both of antimicrobial activity and cytotoxicity study of the nanocomposite ink (PAMPSA-ACY) were also evaluated. Various industries can take the advantage of the current ink as a competent approach for anticounterfeiting purposes., Competing Interests: The authors declare no competing financial interest., (© 2022 The Authors.

The burden of allergic illnesses is continuously rising, and patient diagnosis is a significant problem because of how intricately hereditary and environmental variables interact. The past three to four decades have seen an outbreak of allergies in high-income countries. According to reports on the illness, asthma affects around 300 million individuals worldwide. Identifying clinically important allergens for the accurate classification of IgE-mediated allergy respiratory disease diagnosis would be beneficial for implementing standardized allergen-associated therapy. Therefore, the current study includes an in silico analysis to identify potential IgE-mediated allergens in date palms and cockroaches. Such an immunoinformatic approach aids the prioritization of allergens with probable involvement in IgE-mediated allergic respiratory diseases. Immunoglobulin E (IgE) was used for molecular dynamic simulations, antigen-antibody docking analyses, epitope identifications, and characterizations. The potential of these allergens (Per a7, Per a 1.0102, and Bla g 1.0101) in IgE-mediated allergic respiratory diseases was explored through the evaluation of physicochemical characteristics, interaction observations, docking, and molecular dynamics simulations for drug and vaccine development.

High parity is associated with the risk of fetomaternal complications such as gestational diabetes mellitus, hypertensive disorders, maternal anemia, preterm labor, miscarriage, postpartum hemorrhage, and perinatal and preterm mortality. The objective of the study was to compare fetomaternal complications in women of high parity with women of low parity. This involved a cohort study on a sample size of 500 women who had singleton births. Data were collected from the Maternity and Child Hospital, Ha'il, Kingdom of Saudi Arabia. Participants were classified into two groups according to parity, i.e., women of low parity and women of high parity. Socio-demographic data and pregnancy complications, such as gestational diabetes, hypertension, preeclampsia, intrauterine growth restriction, etc., were retrieved from participants' files. Participants were followed in the postnatal ward until their discharge. The results revealed that women of high parity mostly (49%) were married before 20 years of age, less educated, obese, and were of un-booked cases. Premature babies and fetal mortality are significantly high (0.000) in this group. There is a significant difference between the two groups with respect to maternal anemia, gestational diabetes mellitus, joint pain, perineal tear, miscarriage, postpartum hemorrhage, preeclampsia, vaginal tear, and cesarean section. Determinants responsible for high parity should be identified via evidence-based medicine. Public health education programs targeting couples, weight control, nutrition, and contraception would be a cost-effective strategy for reducing the risk of possible fetomaternal complications.

The devastating COVID-19 pandemic has created several gaps in the management of viral infections, leaving biocontainment and supportive measures as the only resorts for control. As such, there has been a dramatic increase in the use of dietary supplementations and herbal medicine for COVID-19. However, serious concerns regarding the efficacy, safety, and recommended doses of these medicines have been raised. In this study, we aimed to assess the population knowledge about alternative medicine administration for COVID-19 and the associated factors. Using a self-administered cross-sectional survey, we analyzed a total of 2042 valid responses. Most of the included participants were females (69.7%), with an overall mean age of 20.8 ± 11.8 years. Most respondents (62.8%) obtained their knowledge from social media while only 16.6% received knowledge from the health care workers. Half of the participants (50.6%) correctly identified all COVID-19 symptoms, where fever (18.5%) and loss of smell and taste (17.1%) were the most frequent answers. On the use of traditional medicines and supplements for COVID-19, 57.8% did not answer, 23.7% admitted regular use, and 18.5% used sometimes. Family members or friends suggested the use of traditional medicines and dietary supplements to 28.0% of the participants while only 14.7% were advised by a nutritionist, physician, pharmacist, nurse, or a health worker. Moreover, seniors and illiterate portions of society had lower knowledge scores and increased utilization of alternative medicine. Marital status, income, and previous COVID-19 were all significant predictors of the awareness and knowledge score. Thus, this study has identified overuse of unregulated medicinal products in the region, which potentially aggravates COVID-19 or other underlying risks of the disease, making clinical management challenging, particularly in geriatrics and women's health. Regulation of medicinal products and establishment of educational campaigns about the disease have become imperative.

Background: Noise induced hearing loss is the one of the most preventable causes of hearing loss in all age groups. Occupational, environmental, infectious and genetic factors all play a role in determining the level of hearing loss. However, the use of headphones and personal listening devices is now very common, especially in younger generations. Healthy habits are needed to prevent them from developing hearing loss over time. We aim to assess the awareness level of hearing loss among residents of Hail region and its relation to personal listening devices., Methodology: This is a cross-sectional survey based study that was conducted in 2021 over a duration of four months. The survey purpose was to assess the level of awareness about the Relation of Noise-Induced Hearing Loss and Use of Headphones. The questionnaire had a total of 37 questions which were divided into 6 categories. All data was analyzed using SPSS 21, and a p-value of <0.05 was deemed significant., Results: The study included a total of 1086 participants. Sampled population age ranged from 18 to 55 years with a mean age of 24.8 ± 12.6 years old. Meanwhile, 636 (58.6%) of the participants were females and 1074 (98.9%) were Saudi. Hearing problems were significantly higher among those who were exposed to noise at work setting than others (26% vs. 15.9%, respectively; P = .001). Duration of the listening session/per day for more than 5 h was significantly associated with higher rates of hearing problems among participants (33.9% vs. 16.5%, respectively = .001). Typical level of TV or radio volume of 90-100 was associated with hearing problems among 32% compared to 11.2% for 0-49% (P = .001)., Conclusion: There is a low awareness level of hearing loss and its causes among the population with more than half of the respondent having unhealthy habits in listening to sounds through their personal devices. Factors related to develop hearing loss included age, volume level and duration of weekly sessions., Competing Interests: The authors declare no conflict of interest., (© 2021 The Authors.)

Aim: The aim of this study was to explore previous literature related to nurses understanding of Intimate partner violence (IPV) or domestic violence and abuse (DVA) against women and to identify the gaps in nursing education so as to use the findings as a baseline to inform potential intervention strategies, curriculum development and outline implications for future nursing practice., Design: An Integrative review of literature., Methods: Studies were extracted through a search of the electronic databases, such as Science direct, EBSCO host and PubMed, to identify relevant evidences published between January 2000-January 2017. "Joanna Briggs Institute (JBI) tool" was used to review primary research studies., Results: Seventeen empirical studies were analysed. Findings supported four themes including: educational and training experiences, identification of IPV/DVA, curriculum and communication skills of nurses. Continued efforts are further needed to highlight and address IPV/DVA in nursing education and training, to scale up nursing understanding to respond and identify IPV/DVA appropriately in a clinical environment.
