Int Health. 2023 May 19:ihad037. doi: 10.1093/inthealth/ihad037. Online ahead of print.

ABSTRACT

Giardia duodenalis is one of the major causes of diarrhea among children. We performed a systematic review and meta-analysis to assess the prevalence of G. duodenalis and associated risk factors among Asian children. We searched online databases (PubMed, Scopus and Web of Science) and Google Scholar search engine for studies published from 1 January 2000 to 15 March 2022 that measured the prevalence of G. duodenalis among Asian children. Accordingly, the pooled prevalence and 95% CIs were estimated using a random-effects meta-analysis model for the included studies. A total of 182 articles from 22 Asian countries met the inclusion criteria. The pooled prevalence of G. duodenalis infection among Asian children was estimated as 15.1% (95% CI 14.1 to 16%). The highest and lowest pooled prevalence values of G. duodenalis infection were estimated for Tajikistan and China as 26.4% (95% CI 22.9 to 30%) and 0.6% (95% CI 0.001 to 1.02%), respectively. The infection had a higher prevalence in males than in females (OR=1.24; 95% CI 1.16 to 1.31; p<0.001), which was statistically significant. Giardiasis is common among Asian children, hence, a prevention and control scheme of this protozoan in children should be considered by health officials and health policymakers, especially in Asian countries where the prevalence is highest.

Nomograms incorporating primary tumor response at mid-radiotherapy to predict survival in locoregionally advanced nasopharyngeal carcinoma

Head Neck. 2023 May 19. doi: 10.1002/hed.27404. Online ahead of print.

ABSTRACT

BACKGROUND: A nomogram that incorporates tumor response at mid-radiotherapy (mid-RT) to predict the prognosis of locoregionally advanced nasopharyngeal carcinoma (LA-NPC) has not been established.

METHODS: This study retrospectively reviewed 583 patients with LA-NPC who underwent magnetic resonance imaging scans at mid-RT (the fourth week of RT) between 2015 and 2019.

RESULTS: Primary tumor (PT) response at mid-RT was found to predict disease-free survival (DFS) and overall survival (OS). Independent factors from multivariable analysis to predict DFS and OS were assembled into nomograms with (nomograms Amid-RT and Bmid-RT ) or without (nomograms Abaseline and Bbaseline ) PT response. Internal validation revealed good performance of these nomograms in discrimination: C-statistics = 0.761 for nomogram Amid-RT and 0.809 for nomogram Bmid-RT , which showed better discrimination performance than (C-statistics: 0.755) nomogram Abaseline and (C-statistics: 0.798) nomogram Bbaseline (Z-statistic = 2.476, p < 0.05; Z-statistic = 1.971, p < 0.05).

CONCLUSION: The nomograms based on PT response at mid-RT showed favorable predictive accuracy for DFS and OS in patients with LA-NPC.

In silico comparative structural and functional analysis of arsenite methyltransferase from bacteria, fungi, fishes, birds, and mammals

J Genet Eng Biotechnol. 2023 May 19;21(1):64. doi: 10.1186/s43141-023-00522-9.

ABSTRACT

BACKGROUND: Arsenic, a ubiquitous toxic metalloid, is a threat to the survival of all living organisms. Bioaccumulation of arsenic interferes with the normal physiological pathway. To overcome arsenic toxicity, organisms have developed arsenite methyltransferase enzyme, which methylates inorganic arsenite to organic arsenic MMA (III) in the presence of S-adenosylmethionine (SAM). Bacteria-derived arsM might be horizontally transported to different domains of life as arsM or as3mt (animal ortholog). A systematic study on the functional diversity of arsenite methyltransferase from various sources will be used in arsenic bioremediation.

RESULTS: Several arsenite methyltransferase protein sequences of bacteria, fungi, fishes, birds, and mammals were retrieved from the UniProt database. In silico physicochemical studies confirmed the acidic, hydrophilic, and thermostable nature of these enzymes. Interkingdom relationships were revealed by performing phylogenetic analysis. Homology modeling was performed by SWISS-MODEL, and that was validated through SAVES-v.6.0. QMEAN values ranged from – 0.93 to – 1.30, ERRAT score (83-96), PROCHECK (88-92%), and other parameters suggested models are statistically significant. MOTIF and PrankWeb discovered several functional motifs and active pockets within the proteins respectively. The STRING database showed protein-protein interaction networks.

CONCLUSION: All of our in silico studies confirmed the fact that arsenite methyltransferase is a cytosolic stable enzyme with conserved sequences over a wide range of organisms. Thus, because of its stable and ubiquitous nature, arsenite methyltransferase could be employed in arsenic bioremediation.

A novel less-traumatic needle for kidney puncture: first clinical experience

Int Urol Nephrol. 2023 May 19. doi: 10.1007/s11255-023-03584-3. Online ahead of print.

ABSTRACT

INTRODUCTION: To decrease complication rate, we developed a novel MG needle for kidney puncture consisting of a pointed cannula, an atraumatic mandrin-bulb and a spring mechanism pushing the mandrin-bulb forward.

AIM OF THE STUDY: To assess efficacy and safety of kidney puncture during percutaneous nephrolithotomy (PCNL) using a novel less-traumatic MG needle within a clinical trial.

MATERIALS AND METHODS: We conducted a prospective randomized single-center study. In the experimental group, kidney puncture was performed with a novel MG needle while in the control group, standard Trocar or Chiba puncture needles were used.

PRIMARY ENDPOINT: hemoglobin drop.

RESULTS: A total of 67 patients were enrolled. Patients who underwent standard puncture (n = 33) had higher hemoglobin drop in the early postoperative period (p = 0.024). Although there was no statistical difference in overall complication rate between the two groups (p = 0.351), two severe Clavien-Dindo IIIa complications with urinoma occurred in patients from the control group.

CONCLUSION: Less-traumatic needle for kidney puncture may reduce hemoglobin drop and prevent the development of severe complications. At the same time, in terms of stone-free rate (SFR), the efficacy of PCNL remains the same regardless of the needle used for renal access.

Assessing the Interchangeability of AVT02 and Humira® in Participants with Moderate‑to‑Severe Chronic Plaque Psoriasis: Pharmacokinetics, Efficacy, Safety, and Immunogenicity Results from a Multicenter, Double-Blind, Randomized, Parallel-Group Study

BioDrugs. 2023 May 19. doi: 10.1007/s40259-023-00600-x. Online ahead of print.

ABSTRACT

BACKGROUND: The US Food and Drug Administration (FDA) interchangeability guidelines state that the primary endpoint in a switching study should assess the impact of switching between the proposed interchangeable product and the reference product on clinical pharmacokinetics (PK) and pharmacodynamics (if available), as these assessments are generally sensitive to changes in immunogenicity and/or exposure that may arise due to switching. In addition, interchangeability designation requires no clinically meaningful difference in safety and efficacy of switching between the biosimilar and reference, compared with when using the reference product alone.

OBJECTIVES: The aim of this study was to investigate the PK, immunogenicity, efficacy, and safety in participants undergoing repeated switches between Humira® and AVT02 as part of a global interchangeable development program.

METHODS: This multicenter, randomized, double-blind, parallel-group study in patients with moderate-to-severe plaque psoriasis comprises three parts: lead-in period (weeks 1-12), switching module (weeks 12-28), and the optional extension phase (weeks 28-52). Following the lead-in period during which all participants received the reference product (80 mg in week 1, followed by 40 mg every other week), participants with a clinical response of ≥ 75% improvement in the Psoriasis Area and Severity Index (PASI75) were randomized 1:1 to receive AVT02 alternating with the reference product (switching arm) or reference product only (non-switching arm). At week 28, participants who were PASI50 responders could opt to take part in an open-label extension phase receiving AVT02 up to week 50, with an end of study visit at week 52. PK, safety, immunogenicity, and efficacy were evaluated at various timepoints throughout the study for both switching and non-switching arms.

RESULTS: In total, 550 participants were randomized to switching (277) and non-switching arms (273). The switching versus non-switching arithmetic least square means ratio [90% confidence intervals (CIs)] was 101.7% (91.4-112.0%) for the area under the concentration-time curve over the dosing interval from weeks 26-28 (AUCtau, W26-28) and 108.1% (98.3-117.9%) for maximum concentration over the dosing interval from weeks 26-28 (Cmax, W26-28). The 90% CIs for the switching versus non-switching arithmetic means ratio for primary endpoints AUCtau, W26-28 and Cmax, W26-28 were within the prespecified limits of 80-125%, demonstrating comparable PK profiles between groups. In addition, the PASI, Dermatology Life Quality Index, and static Physician’s Global Assessment efficacy scores were highly similar for both treatment groups. There were no clinically meaningful differences between the immunogenicity and safety assessments of repeated switching between AVT02 and the reference product, versus the reference product alone.

CONCLUSIONS: This study demonstrated that the risk, in terms of safety or diminished efficacy of switching between the biosimilar and the reference product, is not greater than the risk of using the reference product alone, as required by the FDA for interchangeability designation. Beyond the scope of interchangeability, a consistent long-term safety and immunogenicity profile, with no impact on the trough levels up to 52 weeks, was established.

CLINICAL TRIAL REGISTRATION: NCT04453137; date of registration: 1 July 2020.

Blood-Based Biomarkers for Managing Workload in Athletes: Considerations and Recommendations for Evidence-Based Use of Established Biomarkers

Sports Med. 2023 May 19. doi: 10.1007/s40279-023-01836-x. Online ahead of print.

ABSTRACT

Blood-based biomarkers can provide an objective individualized measure of training load, recovery, and health status in order to reduce injury risk and maximize performance. Despite enormous potentials, especially owing to currently evolving technology, such as point-of-care testing, and advantages, in terms of objectivity and non-interference with the training process, there are several pitfalls in the use and interpretation of biomarkers. Confounding variables such as preanalytical conditions, inter-individual differences, or an individual chronic workload can lead to variance in resting levels. In addition, statistical considerations such as the detection of meaningful minimal changes are often neglected. The lack of generally applicable and individual reference levels further complicates the interpretation of level changes and thus load management via biomarkers. Here, the potentials and pitfalls of blood-based biomarkers are described, followed by an overview of established biomarkers currently used to support workload management. Creatine kinase is discussed in terms of its evidence for workload management to illustrate the limited applicability of established markers for workload management to date. We conclude with recommendations for best practices in the use and interpretation of biomarkers in a sport-specific context.

Comparison of clinical effectiveness of conbercept and ranibizumab for treating retinopathy of prematurity: a meta-analysis

Int J Clin Pharm. 2023 May 19. doi: 10.1007/s11096-023-01584-y. Online ahead of print.

ABSTRACT

BACKGOUND: Conbercept and ranibizumab have been used to treat retinopathy of prematurity (ROP). However, the clinical effectiveness of conbercept and ranibizumab remains controversial.

AIM: This meta-analysis aimed to compare the effectiveness of conbercept and ranibizumab for treating ROP.

METHOD: We systematically searched Pubmed, Web of Science, Embase, the Cochrane Library, Ovid, Scopus, China National Knowledge Infrastructure, Wanfang Database, CQVIP, Duxiu Database, SinoMed, and X-MOL to screen relevant studies up to November 2022. Retrospective cohort studies and randomized controlled trials (RCTs) evaluating the effectiveness of conbercept and ranibizumab in treating patients with ROP were selected. The outcomes assessed were the rates of primary cure, ROP recurrence, and retreatment. Statistical analysis was performed using Stata.

RESULTS: Seven studies (n = 989) were selected in the meta-analysis. There were 303 cases (594 eyes) treated with conbercept and 686 patients (1,318 eyes) treated with ranibizumab. Three studies reported the primary cure rate. Compared to ranibizumab, conbercept had a significantly higher primary cure rate (odds ratio [OR] 1.91, 95% confidence interval [CI] 1.05-3.49, P < 0.05). Five studies reported the rate of ROP recurrence, and there were no significant differences between conbercept and ranibizumab (OR 0.62, 95% CI 0.28-1.38, P > 0.05). Three studies reported the rate of retreatment, and the rates were not significantly different between conbercept and ranibizumab (OR 0.78, 95% CI 0.21-2.93, P > 0.05).

CONCLUSION: Conbercept had a higher rate of primary cure in ROP patients. More RCTs are needed to compare the efficacy of conbercept and ranibizumab in treating ROP.

An analysis of publications originating from abstracts presented at the Society of American Gastrointestinal and Endoscopic Surgeons (SAGES) Meeting

Surg Endosc. 2023 May 19. doi: 10.1007/s00464-023-10139-1. Online ahead of print.

ABSTRACT

BACKGROUND: Research presentation has benefits, including CV building, networking, and collaboration. A measurable standard for achievement is publication in a peer-reviewed journal. Expectations regarding the likelihood of publication are unknown for studies presented at a national surgical scientific meeting. This study aims to evaluate predictors of manuscript publication arising from abstracts presented at a national surgical scientific meeting.

METHODS: Abstracts presented at the Society of American Gastrointestinal and Endoscopic Surgeons (SAGES) Meeting 2019 were reviewed. Identification of published manuscripts was completed using MedLine, Embase, and Google Scholar 28 months after the presentation to allow for time for publication. Factors evaluated for association with publication included author and abstract measures. Descriptive analyses and multivariable statistics were performed.

RESULTS: 724 abstracts (160 podiums, 564 posters) were included. Of the podium presentations, 128 (80%) were published in a median of 4 months after the presentation. On univariable and multivariable analyses, there was no association between publication and abstract topic, gender, degree, number of publications, or H-indices of first and senior authors. 154 (27.3%) poster presentations were published with a median of 13 months. On univariable analysis, there was a statistically significant difference regarding the abstract topic (p = 0.015) and senior author degree (p = 0.01) between published and unpublished posters. Multivariable analysis demonstrated that colorectal surgery (OR 2.52; CI 1.02-6.23) and metabolic/obesity (OR 2.53; CI 1.09-5.84) are associated with an increased odd of publication. There was an inverse association with female senior authors (OR 0.53; CI 0.29-0.98), while additional degrees (e.g., doctorate and/or master’s degree) of the senior authors were associated with an increased publication rate (OR 1.80; CI 1.00-3.22).

CONCLUSION: 80% of podiums but only 27% of posters were ultimately published. While some predictors of poster publication were noted, it is unclear if these are why these projects fail to publish. Future research is warranted to determine if there are effective strategies to increase poster publication rates.

Is food insecurity related to sustainable and healthy eating behaviors?

Environ Sci Pollut Res Int. 2023 May 19. doi: 10.1007/s11356-023-27694-8. Online ahead of print.

ABSTRACT

In this cross-sectional study, it was aimed to investigate the relationship between sustainable and healthy eating behaviors such as nutritional insecurity and a healthy and balanced diet, interest in regional and organic food products, consumption of seasonal food and avoidance of food waste, preference for locally produced foods, reduction of meat consumption, preference for eggs from free-range chickens, and sustainable fishery products, and consumption of low-fat food products in adults. The study included 410 adults who were reached through social media applications. Data were collected through an online questionnaire including the Descriptive Information Form, the Household Food Insecurity Access Scale (HFIAS), and the Sustainable Healthy Eating Behaviors Scale (SHEBS). The proportion of participants determined as mildly food insecure, moderately food insecure, and severely food insecure was 10.2%, 6.6%, and 7.6%, respectively. Linear regression analysis revealed that in Models 1, 2, and 3, there was a statistically significant negative association between food insecurity and the components of sustainable and healthy eating behaviors such as healthy and balanced diet (β – 0.226, p < 0.001), quality labels (β – 0.230, p < 0.001), seasonal foods, which are of avoidance of food waste (β – 0.261, p < 0.001), animal welfare (β – 0.174, p < 0.001), and fat intake (β – 0.181, p < 0.001). In conclusion, food insecurity negatively affects healthy and balanced diet behaviors, interest in regional and organic food products, seasonal food products consumption and avoidance of food waste, consumption of low-fat food products, and the choice of products such as free-range chicken eggs, and sustainable fisheries.

Bibliometric analysis of global research on bioretention from 2007 to 2021

Environ Sci Pollut Res Int. 2023 May 19. doi: 10.1007/s11356-023-27616-8. Online ahead of print.

ABSTRACT

Bioretention is a typical low impact development (LID) practice that helps reduce peak urban stormwater runoff and runoff pollutant concentrations (e.g., heavy metals, suspended solids, organic pollutants), which has become an important part of urban stormwater management over the past 15 years. To understand the research hotspots and frontiers in the field of bioretention facility research and provide a reference for research into bioretention facilities, we conduct a statistical analysis of global bioretention literature published during 2007-2021 using the Web of Science core database and the data visualization and analysis software VOSviewer and HistCite. The number of published articles related to bioretention facilities shows a rising trend over the study period, with research from China contributing greatly to global research on bioretention facilities. However, the influence of articles needs to be increased. Recent studies mainly focus on the hydrologic effect and water purification effect of bioretention facilities and on the removal of nitrogen and phosphorus nutrients from runoff rainwater. Further studies should focus on the interaction of fillers, microorganisms, and plants in bioretention facilities and its impact on the migration, transformation, and concentrations of nitrogen and phosphorus; the purification effect and mechanism of specific emerging contaminants in runoff; the selection and configuration optimization of filler materials and plant species; and the optimization of the design parameters of the model for bioretention systems.
