Blood Astrocyte Biomarkers in Alzheimer Disease: A Systematic Review and Meta-Analysis.

Neuroinflammation, particularly early astrocyte reactivity, is a significant driver of Alzheimer disease (AD) pathogenesis. It is unclear how the levels of astrocyte biomarkers change in patients across the AD continuum and which best reflect AD-related change. We performed a systematic review and meta-analysis of 3 blood astrocyte biomarkers (glial fibrillary acidic protein [GFAP], chitinase-3-like protein 1 [YKL-40], and S100B) in patients clinically diagnosed with AD. MEDLINE and Web of Science were searched on March 23, 2023, without restrictions on language, time, or study design, for studies reporting blood levels of the astrocyte biomarkers GFAP, YKL-40, or S100B in patients on the AD continuum (including those with mild cognitive impairment [MCI] and dementia) and a cognitively unimpaired (CU) control population. AD diagnosis was based on established diagnostic criteria and/or comprehensive multidisciplinary clinical consensus. Studies reporting indirect biomarker measures (e.g., levels of biomarker autoantibodies) were excluded. Risk of bias assessment was performed using the revised Quality Assessment of Diagnostic Accuracy Studies tool. Pooled effect sizes were determined using the Hedge g method with a random-effects model. The review was prospectively registered on PROSPERO (registration number CRD42023458305). The search identified 1,186 studies; 36 met inclusion criteria (AD continuum n = 3,366, CU n = 4,115). No study was assessed to have a high risk of bias. Compared with CU individuals, patients on the AD continuum had higher GFAP and YKL-40 levels (GFAP effect size 1.15, 95% CI 0.94-1.36, p < 0.0001; YKL-40 effect size 0.38, 95% CI 0.28-0.49, p < 0.0001). Both biomarkers were elevated in more advanced clinical stages of the disease (i.e., in AD dementia compared with MCI due to AD: GFAP effect size 0.48, 95% CI 0.19-0.76, p = 0.0009; YKL-40 effect size 0.34, 95% CI 0.10-0.57, p = 0.0048). No significant differences in blood S100B levels were identified. We demonstrated significant elevations in blood GFAP and YKL-40 levels in patients on the AD continuum compared with CU individuals. Furthermore, within the AD clinical spectrum, significant elevation correlated with more advanced disease stage. Our findings suggest that both biomarkers reflect AD-related pathology. Our findings are limited by the lack of cultural and linguistic diversity in the study populations meta-analyzed. Future meta-analyses using a biomarker-defined AD population are warranted.

IntroductionBreast cancer has become the most common cancer worldwide. Various types of mindfulness-based interventions (e.g., mindfulness-based cognitive therapy, mindfulness-based stress reduction) have been conducted in different delivery methods (including face...

Incidence and prognostic factors of residual back pain in patients treated for osteoporotic vertebral compression fractures: a systematic review and meta-analysis.

Osteoporotic vertebral compression fracture (OVCF) is a common consequence of osteoporosis and can significantly impact the quality of life for affected individuals. Despite treatment options such as vertebroplasty and kyphoplasty, many patients continue to experience residual back pain (RBP) even after the fracture has healed. The incidence of RBP after OVCF treatment varies among studies, and there is a need for further research to understand the risk factors associated with RBP. A systematic review and meta-analysis were conducted following the PRISMA guidelines. Electronic databases were searched, and relevant studies were selected based on inclusion and exclusion criteria. Data extraction and quality assessment were performed independently by two authors. Statistical analysis included single-proportion meta-analyses and pooling of odds ratios (OR) using the inverse-variance method, to calculate the overall incidences of RBP and cement leakage and identify risk factors associated with RBP. A total of 19 studies were included in the analysis. The overall incidences of RBP and cement leakage were found to be 16% and 18%, respectively. Several risk factors were identified, including gender, bone mineral density, depression, baseline visual analog scale (VAS) score, intravertebral vacuum cleft, number of fractured segments, cement distribution, history of vertebral fracture, thoracolumbar fascial injury, and fracture non-union. This study provides potential value within the scope of the incidence and risk factors of RBP following treatment of OVCFs. The identified risk factors can help clinicians identify high-risk patients and tailor appropriate interventions. Future research should focus on standardizing the definition of RBP and patient selection criteria to improve the accuracy of estimates and facilitate better management strategies for OVCF patients.

The effectiveness of stretching exercises in patients with fibromyalgia: A systematic review.

Fibromyalgia is one of the most prevalent chronic pain disorders. Fibromyalgia is characterised by generalised pain. In addition, patients with fibromyalgia often have co-morbidity. Since no cure is available, the treatment is based on symptom management, with physical exercise being the recommended first-line treatment. Different exercise modalities have been examined, including the practice of stretching exercises. The aim of the systematic review is to summarise the efficacy of stretching exercises on fibromyalgia symptoms and to study the content and the quality of the current evidence. The review followed the recommendations of the PRISMA statement. The search for articles was performed in April 2023. We searched on MEDLINE, PubMed, CINAHL, Web of Science, SCOPUS, AMED, PEDro, ClinicalTrials.gov and the Cochrane Collaboration Trials Register. The search was updated in March 2024. The protocol was registered in PROSPERO. Risk of Bias was assessed using the Cochrane Risk of Bias tool, and quality assessment was performed using the GRADE approach. In total, 2586 studies were found in the database searches, of which nine were included in the analysis. The primary outcome was pain. Secondary outcomes were self-reported quality of life, fatigue and physical and mental functioning. The available evidence shows that stretching exercises may improve pain, health-related quality of life and physical and mental functioning, but the level of evidence is low. The main limitation is due to issues with the heterogeneity of the interventions and small sample sizes. Trial registration: PROSPERO registration number CRD42023399614. Key Points •Stretching exercises show promise in the treatment of fibromyalgia. They may improve pain, health-related quality of life, physical functioning and mental health, but the level of evidence is low. •This study goes beyond previous research by presenting a more comprehensive and detailed analysis of the content and methodological quality of the current evidence. •Further research with clearly outlined protocols must be carried out to advance our understanding of the benefits of stretching exercises on fibromyalgia symptoms.

Does HPV vaccination during periconceptional or gestational period increase the risk of adverse pregnancy outcomes?-An updated systematic review and meta-analysis based on timing of vaccination.

The human papillomavirus (HPV) vaccine is crucial in preventing cervical cancer, and a significant number of women in 135 countries worldwide may have unknowingly received the vaccine during peri-pregnancy or pregnancy due to a lack of regular pregnancy testing. Previous studies on the safety of pregnancy outcomes with vaccination before and after pregnancy have not reached definitive conclusions. Thus, we subdivided the vaccination time frame and conducted an updated study to further examine whether exposure to the HPV vaccine during pregnancy or the periconceptional period increases the likelihood of adverse pregnancy outcomes. The clinical trials and cohort studies published before August 1, 2023, were retrieved from PubMed, Embase, Web of Science, and Cochrane Central Register of Controlled Trials. The Newcastle-Ottawa Scale and Cochrane risk of bias assessment tool were adopted to evaluate the risk of bias in the included studies. In addition, the quality assessment was carried out using the Review Manager 5.4 Software, and a meta-analysis was conducted using the Stata 16 Software. Eleven studies were located. The results showed that receiving 4vHPV during the periconceptional or gestational period had no relationship with an increased risk of spontaneous abortion, stillbirth, preterm birth, birth defects, small for gestational age, and ectopic pregnancy. Neither receiving 2vHPV nor 9vHPV was associated with a higher risk of stillbirth, preterm birth, birth defects, small for gestational age, and ectopic pregnancy; however, receiving 2vHPV during the period from 45 days before last menstrual period (LMP) to LMP and 9vHPV during the period from 90 days before LMP to 45 days after LMP seemed to be related to an increased risk of spontaneous abortion (RR = 1.59, 95% CI: 1.04-2.45, RR = 2.04, 95% CI: 1.28-3.24). In conclusion, the likelihood of an elevated risk of spontaneous abortion caused by HPV vaccination during the periconceptional or gestational period could not be completely ruled out. Given the lack of evidence, further research is needed to examine the effect of HPV vaccination on spontaneous abortion.

An evaluation of education videos for women experiencing domestic and family violence in healthcare settings: protocol for a mixed methods systematic review

BackgroundDomestic and family violence (DFV) is a significant public health issue that poses a high risk to women, globally. Women experiencing DFV have higher rates of healthcare utilisation than women not experiencing DFV. Healthcare services are therefore well placed to address DFV and deliver education and awareness interventions to women. Video interventions are a strategy to deliver education to women, while overcoming barriers such as language, literacy, lack of rapport with clinician, or unwillingness to disclose. The current review will aim to further understand the characteristics, methods of evaluation, and outcomes of DFV video education interventions for perinatal women.MethodsThe review will be reported in accordance with the Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols (PRISMA-P) statement. A systematic search will be conducted of the following databases: Medline, Embase, PsycINFO, PsycArticles, Scopus, and Web of Science Core Collection. Two independent reviewers will screen titles and abstracts against the inclusion criteria, followed by a full text screening of eligible articles. A third reviewer will resolve discrepancies. All study types will be included. Only studies published in English will be included. Risk of bias will be assessed using the Quality Assessment with Diverse Studies (QuADS) tool. Data will undergo an aggregate mixed method synthesis informed by The Joanna Briggs Institute, before being analysed using a thematic approach.DiscussionThis systematic review will provide evidence on best practice for the creation, delivery, and evaluation of DFV video interventions for women in the peripartum.Systematic review registrationPROSPERO registration number CRD42023475338.

Assessment of lifestyle factors, stress levels, and quality of life among people with Type 2 Diabetes Mellitus

BackgroundIndia is deemed the “Diabetes Capital,” with over 100 million people suffering from this deadly disease. The disease is a lifestyle disorder and significantly impacts the quality of life. Thus, the study assesses the lifestyle factors and quality of life (QoL) among people suffering from Type 2 Diabetes (T2D).Materials and methodsA cross-sectional study was conducted among 100 T2DM participants aged 18–65. Data were collected from Diabetic Clinics across Pune City using the Modified Diabetes Quality of Life Questionnaire, having seven domains with 17 questions. Perceived Stress Scale (PSS) and International Physical Activity Questionnaire (IPAQ) were used to assess Stress and Physical Activity. Purposive and snowball sampling techniques were used to collect data. The data was entered and cleaned in Microsoft Excel and analysis was done using SPSS v23. Descriptive and inferential analysis was computed.Results60% of the participants were males with a mean age of 43.30 ± 10.89 years. The mean age of women was 50.17 ± 10.13 years. The mean HbA1c of males and females was 7.98 ± 1.41 and 7.83 ± 1.25, respectively. 83% have moderate stress, while 11% have low stress. Only 11% were found to be physically active. The average QoL score of the participants was 63.4 ± 11.2, non-significantly higher in males than in females (64.9 ± 11.03 vs 61.0 ± 11.22). Domain assessment of QoL showed statistical significance among general health (p = 0.002) and energy fatigue (p = 0.015), with males having better general health than women, and energy levels were better in females than males. However, no significance was seen between the genders in physical function, emotional well-being, and role limitation. A statistical significance for energy fatigue (p = 0.031) was observed when QoL was assessed across the disease duration.ConclusionDue to a sedentary lifestyle and increased stress, the glycemic profile of the participants was uncontrolled, which negatively impacted their quality of life. Thus, a holistic approach to managing diabetes will be more beneficial in improving the quality of life.

Spatial and seasonal assessment of surface water quality for domestic use in a semi-arid area of the Upper Kebir Sub-basin, NE Algeria

ABSTRACT The present study was conducted out in the Upper Kebir Sub-basin [North East (NE) Algeria] aiming to evaluate the status and spatial–seasonal variability of water quality for domestic purposes using hydrogeochemical parameters and water quality indices. Surface water samples were collected from selected 27 sites, in the period 2020–2021 during both the wet and dry seasons and were analysed for 22 parameters. The findings were compared with standards and the water quality indices were calculated. The analysis revealed that the basin was mainly polluted and showed significant seasonal and spatial variations in water quality, considerably influenced by climatic conditions (surface runoff) and human activities (urban sewage and agricultural activities). The results reveal significant spatio-temporal fluctuations and highlight areas likely to be affected by anthropogenic activities.

Bone turnover markers in the preoperative assessment of bone quality - A prospective investigation of bone microstructure and advanced glycation endproducts in lumbar fusion patients.

Effective tools to evaluate bone quality preoperatively are scarce and the standard method to determine bone quality requires an invasive biopsy. A non-invasive, and preoperatively available method for bone quality assessment would be of clinical value. The purpose of this study is to investigate the associations of bone formation marker, serum bone alkaline phosphatase (BAP), and bone resorption marker, urine collagen cross-linked N-telopeptide (uNTX) to volumetric bone mineral density (vBMD), fluorescent advanced glycation endproducts (fAGEs) and bone microstructure. A cross-secional analysis using prospective data of patients undergoing lumbar spinal fusion was performed. BAP and uNTX were preoperatively collected. Quantitative computed tomography (QCT) was performed at the lumbar spine (vBMD ≤ 120mg/cm3 osteopenic/osteoporotic). Bone biopsies from the posterior superior iliac spine were obtained and evaluated with multiphoton fluorescence microscopy for fAGEs and microcomputed tomography (µCT) for bone microarchitecture. Correlations between BAP/uNTX to vBMD, fAGEs and µCT parameters were assessed with Spearman's ρ. Receiver operating characteristic (ROC) analysis evaluated BAP and uNTX as predictors for osteopenia/osteoporosis. Multivariable linear regression models adjusting for age, sex, BMI, race and diabetes mellitus determined associations between BAP/uNTX and fAGEs. 127 prospectively enrolled patients (50.4% female, 62.5 years, BMI 28.7kg/m2) were analyzed. uNTX (ρ=-0.331,p < 0.005) and BAP (ρ=-0.245,p < 0.025) decreased with cortical fAGEs, and uNTX (ρ=-0.380,p < 0.001) decreased with trabecular fAGEs. BAP and uNTX revealed no significant correlation with vBMD. ROC analysis for BAP and uNTX discriminated osteopenia/osteoporosis with AUC of 0.477 and 0.561, respectively. In the multivariable analysis, uNTX decreased with increasing trabecular fAGEs after adjusting for covariates (β = 0.923;p = 0.031). This study demonstrated an inverse association of bone turnover markers and fAGEs. Both uNTX and BAP could not predict osteopenia/osteoporosis in the spine. uNTX reflects collagen characteristics and might have a complementary role to vBMD, as a non-invasive tool for bone quality assessment in spine surgery.

Chemical profiling and quality evaluation of raw and vinegar-processing frankincense by multiple UPLC-MS/MS techniques.

Frankincense is used for analgesic, tumor-suppressive, and anti-inflammatory treatments in Traditional Chinese Medicine but poses toxicological concerns. Vinegar processing is a common technique used to reduce the toxicity of frankincense. This study aimed to investigate the chemical composition and quality evaluation of raw and vinegar-processing frankincense by multiple UPLC-MS/MS techniques. Additionally, we purposed refining the vinegar processing technique and identifying potentially harmful ingredients in the raw frankincense. Sub-chronic oral toxicity studies were conducted on raw and vinegar-processing frankincense in rats. The composition of frankincense was identified by UPLC-Q-TOF-MS/MS. Chemometrics were used to differentiate between raw and vinegar-processing frankincense. Potential chemical markers were identified by selecting differential components, which were further exactly determined by UPLC-QQQ-MS/MS. Moreover, the viability of the HepG2 cells of those components with reduced contents after vinegar processing was assessed. The toxicity of raw frankincense is attenuated by vinegar processing, among which vinegar-processing frankincense (R40) (herb weight: rice vinegar weight = 40:1) exhibited the lowest toxicity. A total of 83 components were identified from frankincense, including 40 triterpenoids, 37 diterpenoids, and 6 other types. The contents of six components decreased after vinegar-processing, with the lowest levels in R40. Three components, specifically 3α-acetoxy-11-keto-β-boswellic acid (AKBA), 3α-acetoxy-α-boswellic acid (α-ABA), and 3α-acetoxy-β-boswellic acid (β-ABA), inhibited the viability of HepG2 cells. The processing of frankincense with vinegar at a ratio of 40:1 could be an effective method of reducing the toxicity in raw frankincense. Our research improves understanding of the toxic substance basis and facilitates future assessments of frankincense quality.

Methodological and reporting quality assessment of systematic reviews and meta-analyses in the association between sleep duration and hypertension

ObjectiveIt is crucial to conduct systematic reviews (SRs) and meta-analyses (MAs) to make causal references, in order to inform the clinical guidelines and decision-making. The high reporting quality of reviews through compliance with the guidelines Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) and Assessing the Methodological Quality of Systematic Reviews-2 (AMSTAR-2) could promote the consistency and reproducibility across the published articles. The purpose of this meta-epidemiological study is to evaluate the reporting methodological quality of SRs on the association between sleep duration and hypertension.MethodsAn electronic search in an online database was performed to retrieve systematic reviews and meta-analyses published up to 31st December 2022. Data screening and extraction were conducted by two investigators. The reporting quality of each included article was measured with reference to the 27-item 2020 PRISMA checklist, and methodological quality was evaluated using the AMSTAR-2. PRISMA evaluation was determined by total scores of individual SR and items scores and AMSTAR-2 assessment was also conducted using four categories.ResultsOf 2269 articles captured in the initial search, 15 SRs were included in the final analyses. All SRs had more than one incomplete PRISMA item. The mean of total scores was 20.5 (range 14–25), and the results of the AMSTAR-2 assessment were critically low to low. The reporting quality of “rationale,” “objectives,” “selection process,” “study selection,” “discussion,” and ‘support’ was fully reported. SRs that reported registration information and protocol had a higher PRISMA score than articles that reported certain deficiencies. From the results of the AMSTAR-2 assessment, the methodological quality of these SRs and MAs was critically low to low. None of the included literature provided a list of excluded articles, and the report of the search strategy was incomplete; half of the SRs did not use appropriate tools to assess the risk of bias in each included study.ConclusionsBoth the reporting and methodological quality of overall studies are less than ideal, with several key items being consistently under-reported. The quality measured by AMSTAR-2 is mainly consistent with the quality of reporting. Authors, reviewers, and journal editors should raise awareness and move forward to encourage completeness of SR reporting based on the results, which can aid in enhancing the quality of evidence.Systematic review registrationPROSPERO CRD42023459901.

Interactive Cascaded Network for Prostate Cancer Segmentation from Multimodality MRI with Automated Quality Assessment

The accurate segmentation of prostate cancer (PCa) from multiparametric MRI is crucial in clinical practice for guiding biopsy and treatment planning. Existing automated methods often lack the necessary accuracy and robustness in localizing PCa, whereas interactive segmentation methods, although more accurate, require user intervention on each input image, thereby limiting the cost-effectiveness of the segmentation workflow. Our innovative framework addresses the limitations of current methods by combining a coarse segmentation network, a rejection network, and an interactive deep network known as Segment Anything Model (SAM). The coarse segmentation network automatically generates initial segmentation results, which are evaluated by the rejection network to estimate their quality. Low-quality results are flagged for user interaction, with the user providing a region of interest (ROI) enclosing the lesions, whereas for high-quality results, ROIs were cropped from the automatic segmentation. Both manually and automatically defined ROIs are fed into SAM to produce the final fine segmentation. This approach significantly reduces the annotation burden and achieves substantial improvements by flagging approximately 20% of the images with the lowest quality scores for manual annotation. With only half of the images manually annotated, the final segmentation accuracy is statistically indistinguishable from that achieved using full manual annotation. Although this paper focuses on prostate lesion segmentation from multimodality MRI, the framework can be adapted to other medical image segmentation applications to improve segmentation efficiency while maintaining high accuracy standards.

Infant Cervical Vestibular Evoked Myogenic Potentials: A Scoping Review.

Children diagnosed with hearing loss typically demonstrate increased rates of vestibular loss as compared with their peers, with hearing within normal limits. Decreased vestibular function is linked with delays in gross motor development, acquisition of gross motor skills, and academic challenges. Timely development of sitting and walking gross motor skills aids in the progress of environmental exploratory activities, which have been tied to cognitive, language, and vocabulary development. Considering the time-sensitive development of gross motor skills and cognitive, language, and vocabulary development, identifying vestibular loss in infancy can support early intervention. This scoping review analyzes stimulus, recording, and participant factors relevant to assessing cervical vestibular evoked myogenic potentials (cVEMPs) in the infant population. The scoping literature review was conducted on literature published between 2000 and 2023, focusing on articles assessing cVEMPs in infants. Two authors independently followed Preferred Reporting Items for Systematic and Meta-Analysis guidelines for title and abstract screening, full-text review, data extraction, and quality assessments. Sixteen articles meeting the inclusion criteria were included in the analysis. The existing literature lacks consensus regarding stimulus and recording parameters for measuring infant cVEMPs. In addition, the review reveals a decrease in cVEMP response occurrence rates with the severity of hearing loss, especially in cases of severe to profound hearing loss, compared with mild to moderate sensorineural hearing loss in infants. This scoping review demonstrates the increasing use of cVEMP as a reliable tool for objectively assessing infant vestibular function. The lack of consensus in stimulus and recording parameters emphasizes the need for systematic research to establish an evidence-based protocol for cVEMP measurements in infants. Such a protocol will ensure the reliable measurement of cVEMPs in infants and enhance the effectiveness of cVEMP as part of the infant vestibular test battery. In addition, there is a necessity for a comprehensive large-scale study to evaluate the practicality and feasibility of implementing vestibular screening protocols for infants diagnosed with sensorineural hearing loss in the United States.

The efficacy of psychological interventions for posttraumatic stress disorder symptoms in incarcerated forensic populations: A meta-analysis of randomized controlled trials.

Given the high prevalence of posttraumatic stress disorder (PTSD) symptoms in incarcerated forensic populations, this meta-analysis estimated the efficacy of interventions in this field and explored predictors of intervention outcomes. Twelve randomized controlled trials of psychological interventions for PTSD symptoms in incarcerated forensic populations were included. A combined Hedges's g effect size was synthesized, quality assessments and risk of bias analyses were performed, and publication bias was assessed. Gender and type of control group were explored as predictors. Thirteen comparisons from 12 studies were included in the main analysis. A small to medium combined effect size (g = 0.43, p = .005) was found at posttreatment. The type of control group (p = .156) and gender (p = .953) did not predict outcomes. When we analyzed the available follow-up data (k = 5), the effect was nonsignificant (g = 0.36, p = .123). Study quality was poor and risk of bias high, and studies of first-line PTSD treatments were not found in the literature. A few studies suggest that PTSD treatment may improve symptoms in incarcerated forensic populations, at least temporarily. Follow-up data are still too scarce to draw conclusions about long-term outcomes. Findings of this study indicate that methodologically rigorous outcome research in these populations is needed, with a specific focus on first-line PTSD treatments, long-term efficacy, measurement of recidivism, as well as addressing comorbid conditions given the common complex clinical and social needs in this population.

Adverse Effects of Intravesical OnabotulinumtoxinA Injection in Patients with Idiopathic Overactive Bladder or Neurogenic Detrusor Overactivity: A Systematic Review and Meta-Analysis of Randomized Controlled Studies

Despite the efficacy of onabotulinumtoxinA, its safety profile remains a concern. This meta-analysis reviewed the major adverse events (AEs) associated with intravesical onabotulinumtoxinA treatment in patients with neurogenic detrusor overactivity (NDO) and idiopathic overactive bladder (iOAB). Randomized controlled trials (RCTs) conducted between January 2000 and December 2022 were searched for adult patients administered different onabotulinumtoxinA dosages or onabotulinumtoxinA vs. placebo. Quality assessment was performed using the Cochrane Collaboration tool, and statistical analysis was performed using Review Manager version 5.3. A total of 26 RCTs were included in the analysis, including 8 on NDO and 18 on iOAB. OnabotulinumtoxinA vs. placebo significantly increased the urinary tract infection (UTI) incidence in patients with NDO (relative risk, or RR, 1.54) and iOAB (RR, 2.53). No difference in the RR with different onabotulinumtoxinA dosages was noted. Urinary retention was frequent with onabotulinumtoxinA use in the NDO (RR, 6.56) and iOAB (RR, 7.32) groups. Similar observations were made regarding the risks of de novo clean intermittent catheterization (CIC). The risk of voiding difficulty increased with onabotulinumtoxinA use in patients with iOAB. Systemic AEs of onabotulinumtoxinA, including muscle weakness (RR, 2.79) and nausea (RR, 3.15), were noted in patients with NDO; most systemic AEs had a low incidence and were sporadic.

Proof-of-Stake Non-Fungible Tokens, the Distributed Autonomous Organization, and the Valuation of Art: A Proposal for a Nonprofit, Community Controlled NFT

Abstract This paper describes a way to use blockchain-based non-fungible tokens (NFTs) to address some fundamental failures of the art world introduced when the early-twentieth-century evolution of financial markets expanded to include objets d’art as commodities. It proposes the creation of a distributed autonomous organization (DAO) that uses domain experts’ Delphic consensus methods embedded in smart contracts to provide NFTs with meaningful nonfinancial assessments of intrinsic artistic qualities and merit.

Assessment of water quality in wells and springs across various districts of Taza City, Morocco

ABSTRACT The aim of this study is to assess groundwater pollution in the city of Taza, Morocco. This was accomplished through hydrochemical and biological investigations, focusing on analyzing the physicochemical and bacteriological parameters of groundwater. Water samples were collected from wells and sources within Taza City on a monthly basis during the spring and summer of 2023. These samples were subjected to analysis to identify physicochemical and bacteriological characteristics. The findings revealed multiple contaminations, primarily stemming from two sources: significant microbial pollution observed in 100% of samples due to runoff percolation and discharge of domestic and industrial wastewater, and varying degrees of chemical pollution observed across all samples. The results underscored deviations from national standards, notably in parameters such as dissolved oxygen, nitrate, and nitrite concentrations. These parameters exhibited values either lower or higher than the established norm.

Textbook anastomotic success in patients with low rectal cancer treated by intersphincteric resection: reappraising surgical, oncological, and functional outcomes.

Previous studies on successful anastomosis after intersphincteric resection (ISR) for low rectal cancer (LRC) primarily focused on anastomotic complications rather than functional outcomes. Here, we improved the anastomotic success criteria by considering surgical, oncological, and functional outcomes and proposed a new composite outcome, "textbook anastomotic success" (TASS). This retrospective single-center study included patients with LRC treated with ISR from January 2014 to April 2020. TASS was defined as (1) no anastomotic complications occurring after ISR; (2) ileostomy was closed and there was no severe intestinal dysfunction 2years after ISR; and (3) no local recurrence within 2years of surgery. TASS was achieved upon meeting all indicators. We analyzed 259 patients with LRC, with 125 (48.3%) achieving TASS. Multivariate analysis showed that male sex (OR 0.47; 95% CI 0.27-0.81; p = 0.007), hypertension (OR 0.48; 95% CI 0.24-0.97; p = 0.041), ASA score ≥ 3 (OR 0.28; 95% CI 0.10-0.81; p = 0.018), pre-treatment major low anterior resection syndrome (OR 0.37; 95% CI 0.15-0.94; p = 0.037), and preoperative neoadjuvant chemoradiotherapy (OR 0.41; 95% CI 0.22-0.77; p = 0.006) were independent risk factors for not achieving TASS. Conversely, transverse coloplasty pouch (OR 2.13; 95% CI 1.07-4.25; p = 0.032) and higher anastomosis level (OR 1.56; 95% CI 1.05-2.30; p = 0.026) were independent protective factors for achieving TASS. The nomogram constructed to evaluate the probability of achieving TASS demonstrated good accuracy in the dataset (area under curve, 0.737). TASS provides a comprehensive quality assessment for ISR in patients with LRC. The nomogram predicting TASS may assist surgeons in decision-making for managing LRC.
