ABSTRACT

INTRODUCTION: Down syndrome (DS), a common genetic disorder, leads to various physical, cognitive, and developmental challenges. The supplementary copy of chromosome 21 introduces an abundance of genes, which potentially can influence metabolic irregularities. The aim of the study is to conduct a comprehensive comparative assessment of oxidative stress indicators (TAS, TOS, OSI), BMI, fasting glucose, and insulin levels, HOMA-IR among children and adolescents with DS in contrast to their non-DS siblings.

MATERIAL AND METHODS: and the control group (CG) comprised 20 individuals, siblings of SG (mean age 15.92 years). Anthropometric measurements were conducted. TAS, TOS, fasting glucose, and insulin were assessed. BMI, BMI SDS, OSI and HOMA-IR were calculated.

RESULTS: SG vs. CG: BMI – overweight (29,19% vs. 15%), obese (19,05% vs. 5%); TAS (1.92 mmol/l vs. 1.79 mmol/l (p = 0.0015)); TOS (51.52 mmol/l vs. 33.05 mmol/l (p = 0.014)); OSI (2475.02 vs. 1949,75 (p = 0.038)); no significant differences in fasting glucose, insulin and HOMA-IR. Statistically significant correlations in SG: TOS and BMI, BMI SDS, HOMA-IR; OSI and BMI, BMI SDS, HOMA-IR; HOMA-IR and BMI SDS; fasting insulin and BMI PC; in CG: TAS and BMI; fasting glucose and fasting insulin.

CONCLUSIONS: The research results indicate differences in metabolic processes between the group of individuals with DS compared to the CG, despite shared environmental conditions. The presence of an additional copy of chromosome 21 may contribute to the occurrence of metabolic disorders. These findings emphasize the need for further research that will lead to a better understanding of these relationships and contribute to the development of effective therapeutic strategies.

ABSTRACT

INTRODUCTION: Proper control of blood glucose in children with type 1 diabetes has a direct effect on their metabolism and quality of life by reducing the risk of complications. The use of probiotics may have a beneficial effect on glucose levels.

PURPOSE: The aim of this study was to evaluate the effect of oral consumption of probiotics on glycosylated haemoglobin in children with type 1 diabetes.

MATERIAL AND METHODS: In this single-blind randomized controlled clinical trial, 52 children with type 1 diabetes were studied. We created 2 groups of 26 individuals each. The probiotic group received a daily probiotic capsule for 90 days, in addition to routine insulin therapy. The control group received only insulin therapy. Blood samples were taken to measure HbA1c, fasting plasma glucose, and lipid profiles at the beginning and end of the trial.

RESULTS: The study showed that HbA1c was high in both groups, but this increase was lower in the probiotic group than in the control group. This difference was not statistically significant. The mean level of fasting plasma glucose in the probiotic group was significantly reduced compared to the control group (p = 0.016).

CONCLUSIONS: According to the results of our study, consumption of oral probiotics has no significant effect on HbA1c levels in children with type 1 diabetes mellitus.

ABSTRACT

AIM: To assess the potential heterogeneity in cardiovascular (CV), renal and safety outcomes of canagliflozin between Whites and Asians, as well as these outcomes in each subgroup.

MATERIALS AND METHODS: The CANVAS Program enrolled 10 142 patients with type 2 diabetes, comprising 78.34% Whites and 12.66% Asians. CV, renal and safety outcomes were comprehensively analysed using Cox regression models, while intermediate markers were assessed using time-varying mixed-effects models. Racial heterogeneity was evaluated by adding a treatment-race interacion term.

RESULTS: Canagliflozin showed no significant racial disparities in the majority of the CV, renal and safety outcomes. The heterogeneity (p = .04) was observed on all-cause mortality, with reduced risk in Whites (hazard ratio 0.84; 95% confidence interval 0.71-0.99) and a statistically non-significant increased risk in Asians (hazard ratio 1.64; 95% confidence interval 0.94-2.90). There was a significant racial difference in acute kidney injury (p = .04) and a marginally significant racial heterogeneity for the composite of hospitalization for heart failure and CV death (p = .06) and serious renal-related adverse events (p = .07).

CONCLUSION: Canagliflozin reduced CV and renal risks similarly in Whites and Asians; however, there was a significant racial discrepancy in all-cause mortality. This distinction may be attributed to the fact that Asian patients exhibited diminished CV protection effects and more renal adverse events with canagliflozin, potentially resulting from the smaller reductions in weight and uric acid. These findings highlight the importance of investigating the impact of race on treatment response to sodium-glucose cotransporter-2 inhibitors and provide more precise treatment strategies.

ABSTRACT

CONTEXT.—: Pleural effusion cytology has been widely used in the investigation of pathologic fluid accumulation in pleural spaces. However, up to one-tenth of the cases were not given a definitive diagnosis. These cases have largely been neglected in the bulk of the literature.

OBJECTIVE.—: To provide real-world data on indefinite diagnoses including “atypia of uncertain significance” (AUS) and “suspicious for malignancy” (SFM) in pleural effusion cytology and to investigate pathologists’ practice patterns on using these diagnostic categories.

DESIGN.—: We reported the diagnoses of 51 675 cases. Descriptive statistics and correlation coefficients were used to analyze the relationships between different diagnostic categories and pathologists’ practice patterns and possible explanatory variables.

RESULTS.—: The diagnoses AUS and SFM were reported in 4060 cases (7.86%) and 1554 cases (3.01%) in the cohort, respectively. The mean rates for these indefinite diagnoses varied up to 3-fold between pathologists. Correlations were found between AUS and SFM, as well as between indefinite diagnoses and negative for malignancy (NFM). No correlations were found between pathologists’ years of experience or case volume and the rates of indefinite diagnosis or diagnostic certainty.

CONCLUSIONS.—: A real-world baseline for the rates of indefinite diagnoses in pleural effusion cytology is provided in this large retrospective study. Pathologists show significant variation in their use of indefinite diagnostic categories, and the tendency to use these ambiguous terms was not correlated with individuals’ experience or case volume. How to untangle the intertwined relationship between the uncertainty of indefinite diagnoses and that of NFM requires future prospective studies.

ABSTRACT

BACKGROUND: COVID-19 vaccines have played a crucial role in reducing the burden of the global pandemic. However, recent case reports have indicated the association of the COVID- 19 vaccines with cardiovascular events but the exact association is unclear so far.

OBJECTIVE: Therefore, the objective of the current study is to find out the association of cardiovascular events with COVID-19 vaccines.

METHODS: The COVID-19 Vaccine Knowledge Base (Cov19VaxKB) tool was used to query the Vaccine Adverse Event Reporting System (VAERS) database. The proportional reporting ratio [PRR (≥2)] with associated chi-squared value (>4), and the number of cases > 0.2% of total reports, was used to assess the association of COVID-19 vaccines with cardiovascular events.

RESULTS: A total of 33,754 cases of cardiovascular events associated with COVID-19 vaccines were found in the Cov19VaxKB tool. The cases were observed in different age groups (18-64, and 65 years and above) and gender. The disproportionality measures indicate a statistically significant association between cardiovascular events and COVID-19 vaccines.

CONCLUSION: The current study identified a signal of various cardiovascular events with the COVID-19 vaccines. However, further causality assessment is required to confirm the association.

ABSTRACT

INTRODUCTION: Artificial intelligence (AI) in medical imaging rapidly expands regarding image processing and interpretation. Therefore, the aim was to explore radiographers’ and radiologists’ perceptions and attitudes towards AI use in medical imaging technologies in Saudi Arabia.

METHODS: The survey was distributed online, and responses were collected from 173 participants nationwide. Data analysis was performed using SPSS Statistics (version 27).

RESULTS: The participants scored an average of 1.7, 1.6, and 1.8 on a scale of 1-3 for attitudinal perspectives on clinical application and the positive and negative impact of integrating AI technology in diagnostic radiology. Lack of knowledge (43.9%) and perceived cyber threats (37.7%) were the most cited factors hindering AI implementation in Saudi Arabia.

CONCLUSION: The radiographradiology radiologists in this study had a favorable attitude toward AI integration in diagnostic radiology; nonetheless, concerns were raised about data protection, cyber security, AI-related errors, and decision-making challenges.

ABSTRACT

BACKGROUND: Diabetic retinopathy is the most common complication of diabetes mellitus and is one of the leading causes of vision impairment globally, which is also relevant for the Russian Federation.

OBJECTIVE: To evaluate the diagnostic efficiency of a convolutional neural network trained for the detection of diabetic retinopathy and estimation of its severity in fundus images of the Russian population.

METHODS: In this cross-sectional multicenter study, the training data set was obtained from an open source and relabeled by a group of independent retina specialists; the sample size was 60,000 eyes. The test sample was recruited prospectively, 1186 fundus photographs of 593 patients were collected. The reference standard was the result of independent grading of the diabetic retinopathy stage by ophthalmologists.

RESULTS: Sensitivity and specificity were 95.0% (95% CI; 90.8-96.4) and 96.8% (95% CI; 95.5- 99.0), respectively; positive predictive value – 98.8% (95% CI; 97.6-99.2); negative predictive value – 87.1% (95% CI, 83.4-96.5); accuracy – 95.9% (95% CI; 93.3-97.1); Kappa score – 0.887 (95% CI; 0.839-0.946); F1score – 0.909 (95% CI; 0.870-0.957); area under the ROC-curve – 95.9% (95% CI; 93.3-97.1). There was no statistically significant difference in diagnostic accuracy between the group with isolated diabetic retinopathy and those with hypertensive retinopathy as a concomitant diagnosis.

CONCLUSION: The method for diagnosing DR presented in this article has shown its high accuracy, which is consistent with the existing world analogues, however, this method should prove its clinical efficiency in large multicenter multinational controlled randomized studies, in which the reference diagnostic method would be unified and less subjective than an ophthalmologist.

ABSTRACT

BACKGROUND: There is no high-quality, evidence-based protocol for the treatment of postoperative fatigue syndrome (POFS) after total joint arthroplasty (TJA) or fracture surgery with Chinese herbal medicine (CHM).

PURPOSE: The purpose of this study was to explore the efficacy of CHM in the treatment of POFS after TJA or hip fracture surgery (HFS).

METHODS: We searched six databases to obtain randomized controlled trials (RCTs) of CHM for the treatment of POFS after TJA or HFS. The retrieval time limit was from the establishment of each database to August, 2022. According to the Cochrane Handbook for Systematic Reviews version 5.1, we used RevMan 5.3 to evaluate the quality of the studies. Stata 14.0 software was used to merge and analyze the data. The weighted mean difference (WMD) was the effect estimate for statistical analysis. We also performed subgroup analyses according to different types of surgeries.

RESULTS: A total of 11 RCTs were included in this study, comprising 430 cases in the CHM group and 432 cases in the control group (CG). The meta-analysis results showed that there was no significant difference in the Brief Profile of Mood States (BPOMS) score (WMD=0.08, 95% confidence interval (CI): -0.29 to 0.45, P=0.688), Christensen Fatigue scale (CHFS) score (WMD = 0.15, 95% CI: -0.09 to 0.39, P=0.214) or Identity-Consequence Fatigue Scale (ICFS) score (WMD=-0.40, 95% CI: -1.84 to 1.05, P=0.589) between the CHM group and the CG on the first postoperative day. The use of CHM significantly reduced the BPOMS score (WMD=-0.85 and WMD=-3.01, respectively), CHFS score (WMD=-1.01 and WMD= -1.45, respectively), and ICFS score (WMD=-3.51 and WMD=-5.26) on postoperative days 3 and 7. Compared with the CG, the CHM group had significantly increased serum transferrin and IgG levels on postoperative days 3 and 7. The subgroup analysis results suggested that the application of CHM in HFS patients improved fatigue symptoms on postoperative days 3 and 7, while the application of CHM to treat POFS in TJA patients had great inconsistency in the evaluation of different indicators.

CONCLUSION: The application of CHM improved the fatigue status of POFS patients after TJA or HFS and increased the levels of transferrin and IgG in serum, which is conducive to promoting the postoperative rehabilitation process of patients. The subgroup analysis results showed that the application of CHM to intervene in POFS in HFS patients had obvious benefits.

ABSTRACT

Cancer is a broad category of disease that can start in virtually any organ or tissue of the body when aberrant cells assault surrounding organs and proliferate uncontrollably. According to the most recent statistics, cancer will be the cause of 10 million deaths worldwide in 2020, accounting for one death out of every six worldwide. The typical approach used in anti-cancer research is highly time-consuming and expensive, and the outcomes are not particularly encouraging. Computational techniques have been employed in anti-cancer research to advance our understanding. Recent years have seen a significant and exceptional impact on anticancer research due to the rapid development of computational tools for novel drug discovery, drug design, genetic studies, genome characterization, cancer imaging and detection, radiotherapy, cancer metabolomics, and novel therapeutic approaches. In this paper, we examined the various subfields of contemporary computational techniques, including molecular docking, artificial intelligence, bioinformatics, virtual screening, and QSAR, and their applications in the study of cancer.

ABSTRACT

Examination of the impact of race and ethnicity on multiple myeloma (MM) outcomes has yielded inconsistent results. This retrospective, real-world (RW) study describes patient, disease, and treatment characteristics (and associations with survival outcomes) among newly diagnosed MM patients of non-Hispanic (NH) Black/African American (AA) and NH White race/ethnicity in the United States. We included patients from the nationwide Flatiron Health electronic health record-derived de-identified database who initiated first line of therapy (LOT) for MM between January 1, 2016 and March 31, 2022. Of 4,614 patients in our study cohort, 23.3% were NH Black/AA. Non-Hispanic Black/AA patients were younger than NH White patients at diagnosis (median 68 vs 71 years) and more likely to be female (53.4% vs 43.5%). Rates of high-risk cytogenetics and 1q21+ were similar between races/ethnicities. The most common primary regimen used was lenalidomide-bortezomib-dexamethasone (50.1% of NH Black/AA and 48.1% of NH White patients). Receipt of stem cell transplantation during first LOT was less common among NH Black/AA (16.5%) than NH White (21.9%) patients. Unadjusted RW progression-free survival (rwPFS) and overall survival (rwOS) were similar between races/ethnicities. After multivariable adjustment, NH Black/AA race/ethnicity was associated with slightly inferior rwPFS (hazard ratio [HR] 1.13; 95% CI 1.01-1.27). The difference in rwOS (HR 1.12; 95% CI 0.98-1.28) was not statistically significant. In general, associations between risk factors for rwPFS and rwOS were consistent between races/ethnicities. Findings from this analysis help to inform clinicians about the impact of race/ethnicity on MM treatment paradigms and outcomes in the United States.
