Quality, Reliability, and Readability of Online Information on Idiopathic Intracranial Hypertension.

BACKGROUND: To evaluate the quality & reliability, technical quality, and readability of patient-targeted online information on idiopathic intracranial hypertension. METHODS: In this cross-sectional study, we searched Google and Bing search engines for the terms "idiopathic intracranial hypertension" and "pseudotumor cerebri." We evaluated the first 50 search outcomes for each search term. Peer-reviewed articles, targeted advertisements, book chapters, videos, personal blogs, websites intended for healthcare professionals, and non-English websites were excluded. Websites were classified as institutional or private. Two independent reviewers assessed each website for 1) quality and reliability using DISCERN, Health on the Net Code of Conduct (HONcode), and JAMA criteria and 2) technical quality based on 11 criteria. Readability was evaluated using 6 measures (Flesch-Kincaid Reading Ease score and grade level, Gunning Fog, Simple Measure of Gobbledygook (Smog) index, Coleman-Liau index, and automated readability index). RESULTS: Sixty-three websites (37 institutional) were included. The mean scores for the DISCERN, HONcode, and JAMA criteria were 3.6 ± 1 (1-4.8; 1: worse, 5: best), 10.3 ± 2.8 (2-16; 0: worse, 16: best), and 2 ± 1.3 (0-4; 0: worse, 4: best), respectively. The mean technical quality score was 0.8 ± 0.1 (0.5-1). The mean Flesch-Kincaid grade level score was 8.9 ± 1.8 (3.3-13.3). For Flesch-Kincaid grade level, 47 (74.6%) websites scored a grade level of 10 or less. For Gunning Fog Score, 35 websites (55.6%) scored from 7.3 to 10.8. For the Smog Index, 46 (73%) websites scored 5.7-8. The mean Coleman Liau Index was 16 ± 2.1 (9.6-22.2). For the automated readability index, 30 (50.7%) websites scored less than the eighth grade. No statistically significant difference was present between institutional and private websites except for JAMA, which scored higher in private websites (2.4 vs 1.7, P = 0.03). CONCLUSIONS: Our findings suggest that online information on idiopathic intracranial hypertension/pseudotumor cerebri for patients generally demonstrates moderate to good quality and reliability. Although most websites maintain credible technical quality, the readability exceeds recommended levels for the average American reader. This may impede understanding, emphasizing the need for future improvements.

Effect on physiological parameters and semen quality upon oral administration of fresh onion juice to V-line rabbit buck during severe heat stress.

Severe heat stress is recognized as a factor that severely influences the semen quality and antioxidant status of rabbits. In this context, fresh onion juice (FOJ) may be a safe and useful option to improve reproductive performance. This research was designed to evaluate the anti-stress effects of FOJ on physiological and semen parameters in heat-stressed bucks. Thirty-six V-line rabbit bucks were randomly distributed into three groups. The bucks received FOJ orally at different doses [0 (water), 1.5, and 3 ml/kg live body weight] every 2 days over a period of 2 months, with 3 weeks as an adaptation period. FOJ treatments significantly improved semen characteristics, such as libido, mass and individual sperm motility, semen concentration, sperm viability, and acrosome reaction with increased initial seminal fructose, via the oral administration of 1.5 and 3 mL FOJ/kg body weight, compared with the findings in control bucks. Seminal plasma antioxidant status was significantly enhanced by FOJ treatments. It was concluded that the oral administration of FOJ under severe heat stress can improve bucks' semen characteristics and sex hormone concentrations except for testosterone, and it is considered a good strategy for improving the heat resistance of rabbit bucks, possibly due to its antioxidant activity.

Introducing EL-FIT (Exercise and Liver FITness): A Smartphone App to Prehabilitate and Monitor Liver Transplant Candidates.

Preserved physical function is key for successful liver transplantation (LT); however, prehabilitation strategies are underdeveloped. We created a smartphone application (app), EL-FIT (Exercise and Liver FITness), to facilitate exercise training in end-stage liver disease (ESLD). In this feasibility study, we tested EL-FIT app usage and the accuracy of physical activity data transfer and obtained feedback from initial users. A total of 28 participants used the EL-FIT app and wore a physical activity tracker for 38 ± 12 days (age, 60 ± 8 years; 57% males; Model for End-Stage Liver Disease-sodium, 19 ± 5). There was fidelity in data transfer from the tracker to the EL-FIT app. Participants were sedentary (1957 [interquartile range, 873-4643] steps/day) at baseline. Level of training assigned by the EL-FIT app agreed with that from a physical therapist in 89% of cases. Participants interacted with all app features (videos, perceived exertion, and gamification/motivational features). We rearranged training data to generate heart rate-validated steps as a marker of performance and showed that 35% of the participants had significant increases in their physical performance. Participants emphasized their interest in having choices to better engage in exercise, and they appreciated the sense of community the EL-FIT app generated. We showed that patients with ESLD are able to use and interact with the EL-FIT app. This novel smartphone app has the potential of becoming an invaluable tool for home-based prehabilitation in LT candidates.

First insights into the molecular basis association between promoter polymorphisms of the IL1B gene and Helicobacter pylori infection in the Sudanese population: computational approach.

BACKGROUND: Helicobacter pylori (H. pylori) infects nearly half of the world's population with a variation in incidence among different geographic regions. Genetic variants in the promoter regions of the IL1B gene can affect cytokine expression and creates a condition of hypoacidity which favors the survival and colonization of H. pylori. Therefore, the aim of this study was to characterize the polymorphic sites in the 5'- region [-687_ + 297] of IL1B in H. pylori infection using in silico tools. RESULTS: A total of five nucleotide variations were detected in the 5'-regulatory region [-687_ + 297] of IL1B which led to the addition or alteration of transcription factor binding sites (TFBSs) or composite regulatory elements (CEs). Genotyping of IL1B - 31 C > T revealed a significant association between -31 T and susceptibility to H. pylori infection in the studied population (P = 0.0363). Comparative analysis showed conservation rates of IL1B upstream [-368_ + 10] region above 70% in chimpanzee, rhesus monkey, a domesticated dog, cow and rat. CONCLUSIONS: In H. pylori-infected patients, three detected SNPs (- 338, - 155 and - 31) located in the IL1B promoter were predicted to alter TFBSs and CE, which might affect the gene expression. These in silico predictions provide insight for further experimental in vitro and in vivo studies of the regulation of IL1B expression and its relationship to H. pylori infection. However, the recognition of regulatory motifs by computer algorithms is fundamental for understanding gene expression patterns.

Development of Polyvinyl Alcohol/Kaolin Sponges Stimulated by Marjoram as Hemostatic, Antibacterial, and Antioxidant Dressings for Wound Healing Promotion.

The predominant impediments to cutaneous wound regeneration are hemorrhage and bacterial infections that lead to extensive inflammation with lethal impact. We thus developed a series of composite sponges based on polyvinyl alcohol (PVA) inspired by marjoram essential oil and kaolin (PVA/marjoram/kaolin), adopting a freeze-thaw method to treat irregular wounds by thwarting lethal bleeding and microbial infections. Microstructure analyses manifested three-dimensional interconnected porous structures for PVA/marjoram/kaolin. Additionally, upon increasing marjoram and kaolin concentrations, the pore diameters of the sponges significantly increased, recording a maximum of 34 ± 5.8 µm for PVA-M0.5-K0.1. Moreover, the porosity and degradation properties of PVA/marjoram/kaolin sponges were markedly enhanced compared with the PVA sponge with high swelling capacity. Furthermore, the PVA/marjoram/kaolin sponges exerted exceptional antibacterial performance against Escherichia coli and Bacillus cereus, along with remarkable antioxidant properties. Moreover, PVA/marjoram/kaolin sponges demonstrated significant thrombogenicity, developing high thrombus mass and hemocompatibility, in addition to their remarkable safety toward fibroblast cells. Notably, this is the first study to our knowledge investigating the effectiveness of marjoram in a polymeric carrier for prospective functioning as a wound dressing. Collectively, the findings suggest the prospective usage of the PVA-M0.5-K0.1 sponge in wound healing for hemorrhage and bacterial infection control.

Formulation of Quaternized Aminated Chitosan Nanoparticles for Efficient Encapsulation and Slow Release of Curcumin.

An effective drug nanocarrier was developed on the basis of a quaternized aminated chitosan (Q-AmCs) derivative for the efficient encapsulation and slow release of the curcumin (Cur)-drug. A simple ionic gelation method was conducted to formulate Q-AmCs nanoparticles (NPs), using different ratios of sodium tripolyphosphate (TPP) as an ionic crosslinker. Various characterization tools were employed to investigate the structure, surface morphology, and thermal properties of the formulated nanoparticles. The formulated Q-AmCs NPs displayed a smaller particle size of 162 ± 9.10 nm, and higher surface positive charges, with a maximum potential of +48.3 mV, compared to native aminated chitosan (AmCs) NPs (231 ± 7.14 nm, +32.8 mV). The Cur-drug encapsulation efficiency was greatly improved and reached a maximum value of 94.4 ± 0.91%, compared to 75.0 ± 1.13% for AmCs NPs. Moreover, the in vitro Cur-release profile was investigated under the conditions of simulated gastric fluid [SGF; pH 1.2] and simulated colon fluid [SCF; pH 7.4]. For Q-AmCs NPs, the Cur-release rate was meaningfully decreased, and recorded a cumulative release value of 54.0% at pH 7.4, compared to 73.0% for AmCs NPs. The formulated nanoparticles exhibited acceptable biocompatibility and biodegradability. These findings emphasize that Q-AmCs NPs have an outstanding potential for the delivery and slow release of anticancer drugs.

Efficacy of Glecaprevir and Pibrentasvir in Patients With Genotype 1 Hepatitis C Virus Infection With Treatment Failure After NS5A Inhibitor Plus Sofosbuvir Therapy.

BACKGROUND & AIMS: Treatment options are limited for patients with hepatitis C (HCV) infection with treatment failure after sofosbuvir plus an NS5A inhibitor. There are some data for the efficacy of glecaprevir/pibrentasvir (G/P) in these patients. We performed a randomized trial of the safety and efficacy of 12 and 16 weeks of G/P, with or without ribavirin, in patients with HCV genotype 1 infection with treatment failure after sofosbuvir and an NS5A inhibitor. METHODS: We performed a phase 3b, open-label study of patients with chronic HCV genotype 1 infection who received previous treatment with sofosbuvir plus an NS5A inhibitor. Patients without cirrhosis were randomly assigned to groups that received G/P for 12 weeks (n = 78, group A) or 16 weeks (n = 49, group B). Patients with compensated cirrhosis were randomly assigned to groups that received G/P and ribavirin for 12 weeks (n = 21, group C) or G/P for 16 weeks (n = 29, group D). The primary end point was a sustained virologic response 12 weeks after treatment. Samples collected at baseline and at time of treatment failure were sequenced for resistance-associated substitutions in NS3 and NS5A. RESULTS: Of the 177 patients in the 4 groups, 81% were men, 79% had HCV genotype 1a infection, and 44% were black. Proportions of patients with sustained virologic response 12 weeks after treatment in groups A, B, C, and D were 90%, 94%, 86%, and 97%, respectively. The treatment failed in 13 (7.3%) patients with HCV genotype 1a infection, 6 (7.9%) in group A, 3 (6.1%) in group B, 3 (6.1%) in group C (6.1%), and 1 (3.4%) in group D. Most patients had baseline resistance-associated substitutions in NS5A. Treatment-emergent resistance-associated substitutions in NS3 and NS5A were observed in 9 and 10 patients with treatment failure, respectively. G/P was well tolerated. Ribavirin increased adverse events but did not increase efficacy. CONCLUSIONS: In a randomized study of patients with chronic HCV genotype 1 infection who received previous treatment with sofosbuvir plus an NS5A inhibitor, 16 weeks treatment with G/P produced sustained virologic response 12 weeks after treatment in >90% of patients, including those with compensated cirrhosis.

Post-placental intrauterine device insertion vs puerperal insertion in women undergoing caesarean delivery in Egypt: a 1 year randomised controlled trial.

OBJECTIVE: The aim of the study was to compare 6 month expulsion rates of the copper-bearing intrauterine device (IUD) inserted after delivery of the placenta or at the 6 week postpartum visit in women undergoing caesarean section. METHODS: A parallel-group randomised trial was conducted in an Egyptian university hospital between February 2016 and December 2018. Participants were randomised to either post-placental IUD insertion or IUD insertion at the 6 week postpartum visit. Participants were followed for 12 months. Primary outcomes were IUD expulsion and the proportion of women using an IUD at 6 months. A secondary outcome was the cumulative pregnancy rate at 12 months. RESULTS: Five hundred participants were enrolled in each group. At 6 months the total expulsions were 58/416 (13.9%) in the post-placental group and 4/214 (1.9%) in the puerperal group; IUD use at 6 months was 416/478 (87.0%) in the post-placental group and 214/232 (92.2%) in the puerperal group. Data collected by phone at 12 months showed a higher cumulative pregnancy rate in the puerperal group (84/500, 16.8%) vs the post-placental group (22/500, 4.4%). IUD continuation at 12 months was higher in the post-placental group. CONCLUSION: Participants in the post-placental group had a higher expulsion rate at 6 months, but more IUDs were placed in this group and fewer pregnancies had occurred at 12 months compared with the puerperal group. TRIAL REGISTRATION: Clinicaltrials.gov NCT02679820.

Safety and efficacy of current direct-acting antiviral regimens in kidney and liver transplant recipients with hepatitis C: Results from the HCV-TARGET study.

Data outside of clinical trials with direct-acting antiviral regimens with or without ribavirin as treatment of chronic hepatitis C virus in solid organ transplant recipients are limited. Liver transplant (LT), kidney transplant (KT), and dual liver kidney (DLK) transplant recipients from the Hepatitis C Therapeutic Registry and Research Network database, a multicenter, longitudinal clinical care treatment cohort, treated with direct-acting antiviral regimens between January 1, 2014, and February 15, 2016, were included to assess safety and efficacy. Included were 443 posttransplant patients (KT = 60, LT = 347, DLK = 36); 42% had cirrhosis, and 54% had failed prior antiviral therapy. Most had genotype (GT) 1 (87% with 52% GT1a, 27% GT1b, and 8% GT1 no subtype) and were treated with sofosbuvir (SOF)/ledipasvir ± ribavirin (85%) followed by SOF + daclatasvir ± ribavirin (9%) and ombitasvir/paritaprevir/ritonavir + dasabuvir ± ribavirin (6%). Rates of sustained virologic response (SVR) at 12 weeks were available on 412 patients, and 395 patients (95.9%) achieved SVR at 12 weeks: 96.6%, 94.5%, and 90.9% among LT, KT, and DLK transplant recipients, respectively. Ribavirin did not influence SVR rates and was more often used in those with higher BMI, higher estimated glomerular filtration rate and lower creatinine. Female gender, baseline albumin ≥3.5 g/dL, baseline total bilirubin ≤1.2 mg/dL, absence of cirrhosis, and hepatic decompensation predicted SVR at 12 weeks. Six episodes of acute rejection (n = 2 KT, 4 LT) occurred, during hepatitis C virus treatment in 4 and after cessation of treatment in 2. CONCLUSION: In a large prospective observational cohort study, direct-acting antiviral therapy with SOF/ledipasvir, ombitasvir/paritaprevir/ritonavir + dasabuvir, and SOF plus daclatasvir was efficacious and safe in LT, KT, and DLK transplant recipients; ribavirin did not influence SVR, and graft rejection was rare.

Frequency of mitochondrial m.1555A > G mutation in Syrian patients with non-syndromic hearing impairment.

BACKGROUND: Mitochondrial maternally inherited hearing impairment (HI) appears to be increasing in frequency. The incidence of mitochondrial defects causing HI is estimated to be between 6 and 33% of all hearing deficiencies. Mitochondrial m.1555A > G mutation is the first mtDNA mutation associated with non-syndromic sensorineural deafness and also with aminoglycoside induced HI. Its prevalence varied geographically between different populations. METHODS: We carried out PCR, restriction enzyme based screening, and sequencing of 337 subjects (including 132 patients diagnosed clinically with hereditary deafness) from 54 families from Syria for m.1555A > G mitochondrial mutation. RESULTS: Mitochondrial m.1555A > G mutation was detected in one of fifty-four families (1.85%), six out of the 132 (4.5%) of all patients with NSHI and one propositus of the 205 individuals with normal hearing (0.48%). CONCLUSION: This is the first study to report prelingual deafness causative gene mutations identified by sequencing technology in Syrian families. It is obvious from the results that the testing for the m.1555A > G mutation is useful for diagnosis of hearing loss in Syrian patients and should also be considered prior to treatment with aminoglycosides in predisposed individuals.

Current contraceptive trends among married Egyptian women: a cross-sectional survey.

OBJECTIVE: The aim of our study was to assess the knowledge and attitudes of married Egyptian women towards the different methods of contraception, examining the role of employment and education in modulating contraceptive behaviour. METHODS: A cross-sectional survey was conducted among 2360 Egyptian women between 15 and 45 years of age who were attending outpatient clinics at a university hospital in Cairo between August 2017 and January 2018. The survey collected sociodemographic data as well as information on education, employment, knowledge about contraceptive methods, current and previous use of contraception, source of family planning advice and side effects from previous contraceptive use. RESULTS: The response rate was 90.2%. Current use of a contraceptive method was 38.3%. The intrauterine device (IUD) was the leading contraceptive method (50.7%), followed by oral contraceptives (OCs) (23.6%). Contraceptive prevalence was significantly higher among working women (p < .001), whose primary choice was OCs, while IUD use was significantly higher among non-working women (p < .001). Contraceptive prevalence was highest among women with secondary school education or higher (41.6%). CONCLUSION: Both employment status and educational level of the surveyed women played a significant role in their contraceptive behaviour.

Characteristics of US-Born Versus Foreign-Born Americans of African Descent With Chronic Hepatitis B.

Hepatitis B virus (HBV) infection is more common in African Americans than in white Americans. We compared the epidemiologic, clinical, and virological characteristics of US-born African Americans (USAAs) to those of foreign-born African Americans (FBAAs) with chronic hepatitis B. The adult cohort study of the Hepatitis B Research Network enrolls patients with HBV infection from 21 clinical sites in the United States and Canada. A total of 237 (15%) of the adult participants with chronic HBV infection that were enrolled from January 20, 2011, to October 2, 2013, were of African descent, including 57 USAAs and 180 FBAAs (76%). Compared with FBAAs, USAAs were older and more likely to have acquired HBV through sexual exposure, to be HBeAg-positive, to have higher HBV DNA levels, and to be infected with HBV genotype A2. FBAAs from West Africa were more likely to have elevated serum alanine aminotransferase (72% vs. 50%; P < 0.01) and higher HBV DNA levels (median, 3.2 log10 IU/mL vs. 2.8 log10 IU/mL; P = 0.03) compared with East African FBAAs. The predominant HBV genotype among West African FBAAs was E (67%), whereas genotypes A (78%) and D (16%) were common in East African FBAAs. Significant differences were found between USAAs and FBAAs, highlighting the need for tailored strategies for prevention and management of chronic HBV infection for African Americans.

Sofosbuvir plus ledispasvir for recurrent hepatitis C in liver transplant recipients.

Hepatitis C virus (HCV) recurrence after liver transplantation (LT) is associated with worse outcomes. The combination of ledipasvir (LDV) and sofosbuvir (SOF) has been approved for HCV treatment after LT, but there are limited data on the effectiveness and safety of LDV/SOF in the "real-world" setting. This multicenter study is the largest report to date on the effectiveness and safety of LDV/SOF in the post-LT setting. A total of 204 patients (72% male, 68% Caucasian, 66% genotype [GT] 1a, 21% METAVIR F3-F4, 49% treatment-experienced) were treated with LDV/SOF. The mean duration from LT to treatment initiation was 4.8 years. The overall sustained virological response rate 12 weeks after completion of therapy (SVR12) was 96%. Patients treated with 8 or 12 weeks of LDV/SOF without RBV experienced an SVR12 rate of 100% and 96%, respectively. Calcineurin inhibitors were used in 89% of patients, and 32% of patients underwent adjustment in immunosuppression during treatment. One episode of mild rejection, responsive to an increase in immunosuppression dosage, was observed. There was no graft loss attributed to HCV treatment. Four deaths occurred unrelated to HCV treatment, and no significant serious adverse events were documented. In conclusion, SOF and LDV with or without RBV for 8, 12, or 24 weeks in post-LT patients was effective and safe with a high SVR12 rate across a spectrum of GTs and stages of fibrosis.

The effectiveness of physical activity interventions on blood pressure in children and adolescents: A systematic review and network meta-analysis.

BACKGROUND: High blood pressure (BP) is a major contributor to mortality and cardiovascular diseases. Despite the known benefits of exercise for reducing BP, it is crucial to identify the most effective physical activity (PA) intervention. This systematic review and network meta-analysis (NMA) aimed to evaluate the available evidence on the effectiveness of various PA interventions for reducing BP and to determine their hierarchy based on their impact on BP. METHODS: A search of PubMed, SPORTDiscus, PsycINFO, Web of Science, CINAHL, Cochrane, and Eric databases was conducted up to December 2022 for this systematic review and NMA. Randomized controlled trials and quasi-experimental studies targeting healthy children and adolescents aged 6-12 years old were included in this study. Only studies that compared controlled and intervention groups using PA or exercise as the major influence were included. We followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Three independent investigators performed the literature screening, data extraction, and risk of bias assessment. We used Bayesian arm-based NMA to synthesize the data. The primary outcomes were systolic BP and diastolic BP. We calculated the mean differences (MDs) in systolic BP and diastolic BP before and after treatment. Mean treatment differences were estimated using NMA and random-effect models. RESULTS: We synthesized 27 studies involving 15,220 children and adolescents. PA combined with nutrition and behavior change was the most effective intervention for reducing both systolic BP and diastolic BP (MD = -8.64, 95% credible interval (95%CI):-11.44 to -5.84; MD = -6.75, 95%CI: -10.44 to -3.11), followed by interventions with multiple components (MD = -1.39, 95%CI: -1.94 to -0.84; MD = -2.54, 95%CI: -4.89 to -0.29). CONCLUSION: Our findings suggest that PA interventions incorporating nutrition and behavior change, followed by interventions with multiple components, are most effective for reducing both systolic BP and diastolic BP in children and adolescents.

Scuttle fly Megaselia scalaris (Loew) (Diptera: Phoridae) endoparasitoid as a novel biocontrol agent against adult American cockroaches (Periplaneta americana).

The American cockroach, Periplaneta americana (Linnaeus, 1758) (Blattodea: Blattidae), is one of the most common pests that thrive in diverse environments and carries various pathogens, causing critical threats to public health and the ecosystem. We thus report in this study the first observation of decapitated American cockroaches as a result of infestation with scuttle fly parasitoids. Interestingly, behavioral alterations in the form of zombification-like behavior could be observed in cockroaches reared in the laboratory before being decapitated, implying that the insect targets cockroach heads. To identify this parasitoid, cockroaches' corpora were isolated in jars, and apodous larvae were observed. Larvae developed into small coarctate pupae, and adults emerged. The scuttle flies were collected and exhibited tiny black, brown, to yellowish bodies. The fly was initially identified based on its morphological properties as a member of the order Diptera, family Phoridae. To provide further insights into the morphological attributes of the phorid species, the fly was examined using a scanning electron microscope (SEM) and then identified as Megaselia scalaris accordingly. SEM analysis revealed the distinctive structure of M. scalaris concerning the head, mouth parts, and legs. Specifically, the mouth parts include the labrum, labellum, rostrum, and maxillary palps. Although further investigations are still required to understand the complicated relationships between M. scalaris and American cockroaches, our findings provide a prominent step in the control of American cockroaches using M. scalaris as an efficient biological control agent.

Decision-making on peri-implant mucositis management and treatment approaches.

Peri-implant mucositis is characterised by inflammation of soft tissues surrounding a dental implant without associated bone loss beyond initial remodelling. Early detection and timely intervention are critical to prevent its progression to peri-implantitis. This paper focuses on various treatment options for treating peri-implant mucositis. The cornerstone of professional treatment lies in the mechanical disruption and removal of microbial biofilms around the implant. This can be achieved through careful use of manual or powered instruments, such as ultrasonic scalers or air polishing devices. However, there is a need for further research to determine the most effective single approach for treating peri-implant mucositis. Current evidence does not support the combination of mechanical debridement with locally administered antibiotics. Contrarily, evidence strongly supports the removal, cleaning, and modifications of prostheses to improve both self-performance and professional cleanability. The use of adjunctive therapies like photodynamic therapy and diode laser, in conjunction with mechanical instrumentation, is not currently recommended due to the limited strength of available evidence. Preventive measures emphasise the importance of comprehensive oral hygiene care, encompassing professional guidance and at-home practices, to manage biofilms effectively. This encompasses oral hygiene instruction, regular debridement, and maintenance care. Supporting peri-implant therapy is also vital for ongoing implant monitoring, preventing the recurrence of mucositis, and halting its progression to peri-implantitis. This multifaceted approach is key to effectively managing and treating peri-implant mucositis.

Prediction of the most deleterious non-synonymous SNPs in the human IL1B gene: evidence from bioinformatics analyses.

BACKGROUND: Polymorphisms in IL1B play a significant role in depression, multiple inflammatory-associated disorders, and susceptibility to infection. Functional non-synonymous SNPs (nsSNPs) result in changes in the encoded amino acids, potentially leading to structural and functional alterations in the mutant proteins. So far, most genetic studies have concentrated on SNPs located in the IL1B promoter region, without addressing nsSNPs and their association with multifactorial diseases. Therefore, this study aimed to explore the impact of deleterious nsSNPs retrieved from the dbSNP database on the structure and functions of the IL1B protein. RESULTS: Six web servers (SIFT, PolyPhen-2, PROVEAN, SNPs&GO, PHD-SNP, PANTHER) were used to analyze the impact of 222 missense SNPs on the function and structure of IL1B protein. Five novel nsSNPs (E100K, T240I, S53Y, D128Y, and F228S) were found to be deleterious and had a mutational impact on the structure and function of the IL1B protein. The I-mutant v2.0 and MUPro servers predicted that these mutations decreased the stability of the IL1B protein. Additionally, these five mutations were found to be conserved, underscoring their significance in protein structure and function. Three of them (T240I, D128Y, and F228S) were predicted to be cancer-causing nsSNPs. To analyze the behavior of the mutant structures under physiological conditions, we conducted a 50 ns molecular dynamics simulation using the WebGro online tool. Our findings indicate that the mutant values differ from those of the IL1B wild type in terms of RMSD, RMSF, Rg, SASA, and the number of hydrogen bonds. CONCLUSIONS: This study provides valuable insights into nsSNPs located in the coding regions of IL1B, which lead to direct deleterious effects on the functional and structural aspects of the IL1B protein. Thus, these nsSNPs could be considered significant candidates in the pathogenesis of disorders caused by IL1B dysfunction, contributing to effective drug discovery and the development of precision medications. Thorough research and wet lab experiments are required to verify our findings. Moreover, bioinformatic tools were found valuable in the prediction of deleterious nsSNPs.

Smartphone app-based interventions on physical activity behaviors and psychological correlates in healthy young adults: A systematic review.

BACKGROUND: The issue of low physical activity (PA) levels among the youth is a longstanding concern. Smartphone applications offer a promising avenue for delivering interventions that are both accessible and engaging. Up to now, there appears to be a gap in the literature, with no systematic reviews assessing the efficacy of smartphone apps in encouraging increased physical activity among healthy young adults. OBJECTIVE: To synthesize the effects of a smartphone app-based intervention on PA and PA-related psychological correlates in healthy young adults (18-35 years old). METHODS: A search was conducted on eighteen databases: PubMed, Medline, Web of Science, SPORTDiscus, Scopus, Academic Search Premier, Communication and Mass Media Complete, Article First, Biomed Central, BioOne, EBSCOHost, JSTOR, ProQuest, SAGE Reference Online, ScienceDirect, SpringerLink, Taylor&Francis, and Wiley Online. The search covered the period up until December 2023. This research included all randomized controlled trials (RCTs) that evaluated the effectiveness of smartphone app-based interventions on PA and PA related psychological outcomes in healthy young adults. The overall impact was determined by vote counting based on the direction of effect and aggregating p values. The quality of the evidence was evaluated using an 8-item scale. This study has been registered in the PROSPERO database with the identification number CRD42023390033. RESULTS: A total of 8403 articles were retrieved, and based on the predefined inclusion and exclusion criteria, seven articles were selected for inclusion. Among these articles, four high-quality RCTs were identified, and the results of vote counting and combining p values methods suggested that smartphone-based app interventions did not demonstrate significant effectiveness in improving PA and PA-related psychological outcomes. However, some improvements were observed. The analysis results, which were categorized into fitness apps and health apps based on the characteristics of the interventions, also failed to demonstrate significant intervention effects. CONCLUSION: The findings indicate that, currently, there are no significant effects of smartphone app interventions on improving PA and PA-related psychological outcomes in healthy young adults aged 18-35 years. It is important to note that these findings should be interpreted with caution due to the limited number of included studies. Future research should focus on employing high-quality study designs to determine the true effects of interventions and analyze various smartphone app interventions. These analyses should encompass different app characteristics (e.g., fitness app and health app), various combinations (e.g., fitness app alone and fitness app in combination with other interventions), diverse intervention goals (e.g., PA and PA along with other outcomes), and multiple intervention characteristics (e.g., frequency and duration).
