ABSTRACT

BACKGROUND: Precise benign and malignant breast tumors classification is essential for effective treatment planning and outcome prognostication. Medical imaging’s capability to classify breast tumors has been greatly improved by the accelerated advancement of artificial intelligence (AI). This research presents a comprehensive evaluation of the efficiency of AI-assisted ultrasound elastography (UE) specifically applied to classify benign and malignant breast tumors for the first time.

METHODS: We conducted extensive literature search in PubMed, Embase, IEEE, Web of Science, Cochrane Library, China National Knowledge Infrastructure (CNKI), Wanfang database, and China Biology Medicine disc (CBM) to identify relevant studies that applied or developed AI algorithms for classifying benign and malignant breast masses employing UE. We used bivariate mixed-effects model for statistical analysis, obtaining binary diagnostic accuracy data to generate pooled estimates (e.g., sensitivity and specificity). The Quality Assessment of Diagnostic Accuracy Studies-AI (QUADAS-AI) tool was applied to assess the methodological quality of the included research. Sensitivity analysis was conducted to verify the robustness of the findings, and Deeks’ funnel plot was employed to examine potential publication bias. Meta-regression analysis was used to investigate the sources of heterogeneity. Clinical applicability was evaluated by Fagan nomogram.

RESULTS: The meta-analysis comprised sixteen relevant studies. Summary estimates indicated high diagnostic accuracy: the pooled sensitivity was 0.90 (95% CI: 0.85-0.94), the pooled specificity was 0.88 (0.81-0.93), the positive likelihood ratio (PLR) was 7.5 (4.7-11.9), and the negative likelihood ratio (NLR) was 0.11 (0.07-0.18). The diagnostic odds ratio (DOR) was 67 (33-137), and the area under the summary receiver operating characteristic curve (AUC) was 0.95 (0.93-0.97).

CONCLUSION: AI-assisted UE demonstrates outstanding performance in benign and malignant breast tumors classification. This study was registered with PROSPERO (CRD42024590031).

ABSTRACT

BACKGROUND: Iron folic acid supplementation is one of the most global public health interventions to alleviate iron deficiency anemia during pregnancy. Both folic acid and iron deficiencies constitute the major micronutrient deficiencies in Ethiopian women. Non-adherence to folic acid supplementation is a factor for iron deficiency anemia among pregnant women including at selected study area, OBJECTIVE: To identify determinants of non-adherence to iron-folic acid intake among pregnant women who attended antenatal care in Bishoftu town public health facilities, Ethiopia 2022.

METHODS: Facility-based unmatched case-control study was conducted from April 1 to May 30, 2022. A total of 105 cases and 211 controls of pregnant women participated in the study by using systematic random sampling methods for control and consecutive sampling was used for the case. Cases were pregnant women who started ANC service and take iron/folate supplements one month before data collection and who received IFA tablets less than 4 days per week. Controls were pregnant women who started ANC service and take iron/folate supplements one month before data collection and who take IFA tablets greater or equal to 4 days per week. Data were collected by trained health workers using interviewer administered structured questionnaires, entered into Epi-data version 4.6, and exported to Statistical Package for Social Sciences version 25 for analysis. Logistic regression was used to identify determinants of the non-adherence to iron-folic acid supplementation, and the variables with p-value < 0.25 were recruited for multivariable analysis, and an adjusted odds ratio with a 95% confidence interval and a p-value of ≤ 0.05 was used to declare the statistical significance of the variables.

RESULTS: Of the identified determinants of non-adherence to iron-folic acid supplementation:- women aged 15-24 years and 25-34 years [AOR = 5.0, 95% CI (3.04, 12.80), AOR = 11.8, 95% CI (8.01, 12.60)], women who started first ANC > 16 weeks (AOR = 2.41, 95% CI:1.11, 5.25), women who received ANC visit two and three [AOR = 5.17, 95% CI (2.50, 13.02), AOR = 2.95 95% CI (1.26, 6.80)], women with inadequate knowledge (AOR = 3.5,95% CI:1.70,7.20), women who received 30 and below tablets (AOR = 7.80, 95% CI:4.01, 18.02) were the determinants of non-adherence to iron-folic acid supplementation.

CONCLUSIONS: Women’s age, pregnancy weeks during first ANC, frequency of ANC follow-up, knowledge of women on iron-folic acid supplementation, women who received 30 and below tablets were significant predictors for non-adherence to folic acid supplementation. Thus, the town health office should work on non-adherence to folic acid supplementation during pregnancy to improve knowledge of all age groups of women during ANC visits with concerned stakeholders.

ABSTRACT

BACKGROUND: In Dutch general practice, urinary tract infections (UTIs) are the most common indication for prescribing antibiotics. General practice assistants (GPAs) are the first point of contact for patients with UTI-associated symptoms and sometimes even manage these cases without consulting a general practitioner. Nevertheless, literature on how GPAs provide and experience UTI-care is limited.

METHODS: To investigate the knowledge, attitude, and practice of Dutch GPAs regarding UTIs in general practice, we constructed a cross-sectional online survey. The survey assessed actively working Dutch GPAs’ knowledge, practice, and attitude in UTI-care. Participants were recruited through social media platforms in May and June 2024. Descriptive statistics were used to perform primary data-analysis. Secondary analysis was performed using univariate and multivariate logistic regression models.

RESULTS: 478 of the 643 obtained responses were eligible for analysis. Results showed 95.8% of the GPAs think their UTI knowledge is sufficient. However, only one-fourth of respondents selected all correct groups at higher risk of developing a complicated UTI. Additionally, almost 70% of the respondents would perform urinalysis as a precaution if a patient hands in urine, even when UTI-associated symptoms are absent. Nine out of ten GPAs would never disregard urinalysis results. Furthermore, while GPAs indicated to apply shared decision-making often, wait-and-see policies are not regularly advised.

CONCLUSIONS: GPAs seem to be unaware of their limitations regarding UTI-care, especially overvaluing the urine dipstick as a diagnostic tool. GPAs should adjust their preconceived notions of patient preferences, since patients’ willingness to try non-antibiotic treatments is higher than they think.

ABSTRACT

PURPOSE: Serous cystadenomas (SCAs), solid pseudopapillary neoplasms (SPNs), neuroendocrine neoplasms (NENs), and mucinous cystic neoplasms (MCNs) are pancreatic tumors that frequently develop calcifications. Identifying the presence and pattern of calcifications on unenhanced CT scans can significantly aid radiologists in differential diagnosis.

METHODS: Patients were included if they had a confirmed diagnosis through pathology or endoscopic ultrasound and MRI follow-up for at least one year. Exclusion criteria were the absence of CT imaging and multiple pancreatic lesions. Two radiologists independently reviewed unenhanced CT scans to assess lesion location, size, presence of calcifications, and calcification patterns, categorized as Type 1 (punctate), Type 2 (curvilinear/elongated), and Type 3 (coarse). Statistical analysis was performed using Fisher’s test for categorical variables, Kruskal-Wallis and Mann-Whitney tests for numerical variables, and logistic regression models to assess the impact of calcification patterns on diagnosis. Sensitivity, specificity, accuracy, and AUC-ROC were calculated for predictive models.

RESULTS: 311 patients (mean age 61 ± 14 years; 56.9% female) were included. Calcifications were present in 27.7% of cases. Calcified NENs and SPNs were more frequently in the body/tail (p = 0.003), and calcified NENs were larger than non-calcified ones (p < 0.001). Punctate calcifications were most common in NENs, while coarse calcifications predominated in SCAs, decreasing the likelihood of a NEN diagnosis and increasing the probability of SCA. The AUC-ROC values were 0.891 for NENs and 0.986 for SCAs.

CONCLUSIONS: Approximately 30% of pancreatic tumors exhibit calcifications. Punctate intratumoral calcifications are more indicative of NENs, whereas coarse calcifications strongly suggest SCAs, influencing the differential diagnosis.

ABSTRACT

Nearly half of patients with dementia have comorbid hypertension. However, evidence on the clinical outcomes of antihypertensive medications (AHMs) in these patients remains inconsistent. This review synthesises evidence on cognitive, functional and behavioural outcomes, cardiovascular events, hospitalisation, mortality and adverse drug events related to the use of AHMs in patients with dementia. The review was registered with PROSPERO (CRD42024619054) and is reported following the PRISMA guidelines. We searched MEDLINE, Embase, CENTRAL, PsycINFO, CINAHL and Google Scholar. Random-effects meta-analyses were conducted. We included 36 studies (10 randomised controlled trials (RCTs) and 26 observational follow-up studies) involving 276,793 patients. Meta-analysis showed a small but statistically significant cognitive benefit with AHM use versus non-use in observational studies (standardised mean difference (SMD) 0.23; 95% CI 0.20 to 0.27; p < 0.001), but not in RCTs (SMD – 0.01; 95% CI – 0.16 to 0.14; p = 0.92). Associations with functional outcomes (SMD 0.45; 95% CI – 0.52 to 1.42; p = 0.36), behavioural outcomes (SMD – 0.11; 95% CI – 0.79 to 0.57; p = 0.75) and mortality (hazard ratio 1.32; 95% CI 0.41 to 4.27; p = 0.64) were not significant. Regimens containing renin-angiotensin system blockers (RASBs) showed less cognitive decline compared to other AHMs. Data on the cardiovascular outcomes of AHM use were limited. In summary, AHM use was associated with slower cognitive decline in observational studies (not in RCTs), but no significant relationships with functional, behavioural, or mortality outcomes. The slowed cognitive decline was most pronounced with RASBs. More research, especially RCTs, examining the clinical benefits of AHM use in people with dementia is required.

ABSTRACT

BACKGROUND: Robotic surgery demands specialized training to ensure proficiency and patient safety. Deliberate practice using Virtual Reality (VR) robotic simulation platforms provides a safe method for skill acquisition. The first part of our Initial curriculum (IC) consisted of 33 VR drills on the SimNow Simulator, which was refined in 2021 to 19 VR drills using a Simulation-Based Mastery Learning (SBML) approach. This study evaluates the feasibility and effectiveness of our refined curriculum (RC).

METHODS: A total of 87 general surgery residents were included. IC was completed by 41 residents, while 46 residents completed the RC. Metrics such as console time, pre- and post-test VR drill scores, and inanimate drill performance were assessed. Statistical analyses included independent or paired t-tests and Mann-Whitney U, or Wilcoxon Signed Rank tests for non-parametric data.

RESULTS: In the IC, 83% of participants achieved mastery versus 100% in the RC. Mean console training time was significantly reduced from 7 h 6 m (95% CI: 6.20-7.92) in the IC to 5 h 42 m (95% CI: 4.74-6.10) in the RC (p = 0.005), demonstrating enhanced efficiency. For VR drills, the IC median score improved from 62 (126-28) to 353 (366-317) (p < 0.001), with a median time reduction of 847 s (1169-565) (p < 0.001). In the RC, the median test score improved from 65.5 (138.75-37.75) to 344.5 (365.5-291.25) (p < 0.001), with a median time reduction of 999 s (1449.5-548.25) (p < 0.001). Inanimate drill times also improved: the IC median time decreased from 928.5 s (1066-853.5) to 741.5 s (859-613.5) (p < 0.001), while the RC median time decreased from 909.5 s (1037.7-744.7) to 464.5 s (518-413.7) (p < 0.001).

CONCLUSION: Reducing VR drills from 33 to 19 content-aligned drills with new proficiency benchmarks maintained effectiveness while significantly decreasing VR console training time. These findings support the feasibility of implementing this streamlined robotic training curriculum in general surgery residency programs without compromising skill acquisition.

ABSTRACT

Clostridioides difficile infection (CDI) poses a significant healthcare burden. Patients with diabetes mellitus (DM) are at increased risk of poor outcomes. This study aims to compare CDI outcomes, including mortality, in patients with and without DM. Retrospective data between (2014-2024) from Clalit Health Services (CHS) electronic database were analyzed. Among 2319 patients with confirmed CDI, 1005 had DM, and 1314 did not. DM patients were significantly older (74.5 ± 12.0 vs. 68.6 ± 20.4 years; p < 0.001), more likely to be male (p = 0.029), and disproportionately represented in lower socioeconomic status (SES) groups (30.1% vs. 22.4%; p < 0.001). Additionally, patients with DM had a significantly higher prevalence of comorbidities, with a median Charlson comorbidity Index (CCI) of 7.5 compared to 4.9 (p < 0.001), along with higher serum creatinine levels and lower albumin levels (p < 0.001). All-cause mortality was significantly higher in the DM group (p < 0.001). Deceased patients were notably older (p < 0.001), more likely male, and had lower SES (27% vs. 25.1%, p = 0.028). Patients with DM and CDI exhibited different comorbidities compared to those without diabetes. DM, advanced age, low SES, and male gender are linked to poorer outcomes, including mortality, among patients with CDI. These findings underscore the need for intensive management in patients with diabetes and CDI.

ABSTRACT

Graft restenosis remains a significant challenge in coronary artery bypass grafting (CABG). Traditional function assessments, primarily relying on blood flow rate, often fail to capture the geometric and hemodynamic influences on graft patency. To address these limitations, this retrospective study aimed to establish a comprehensive risk prediction model that incorporates both flow dynamics and geometric features, facilitating clinically applicable evaluations. A total of 110 patient-specific CABG geometries were reconstructed from coronary computed tomography angiography (CCTA) images to extract key geometric parameters for subsequent statistical analysis. An additional 28 cases were analyzed for statistical and hemodynamic validation. Three logistic regression models were built and validated for restenosis risk prediction. Computational fluid dynamics (CFD) simulations were performed to investigate the hemodynamic characteristics of high-risk grafts. A MATLAB-based software tool was also developed to automate the analysis workflow. Among the three prediction models, the one combining graft flow and geometric factors balanced sensitivity and specificity, and performed best in the validation cohort (area under curve = 0.758, sensitivity = 89.1 %). CFD simulations on the validation cohort confirmed that grafts with high predicted risk exhibited poor hemodynamic conditions, including low time-averaged wall shear stress, high oscillatory shear index, and high relative residence time. Further statistical analysis revealed complex context-dependent interactions between graft flow and geometry. This study presents an integrated approach to restenosis risk prediction by combining patient-specific flow and geometric features. These findings are expected to enhance clinical decision-making and support more individualized postoperative management strategies in CABG.

ABSTRACT

OBJECTIVE: To evaluate the safety and feasibility of transaxillary robotic thyroidectomy (TART) in Japan by comparing early cases with video-assisted neck surgery (VANS).

METHODS: Single-center retrospective review of 31 consecutive thyroid lobectomies: 16 VANS (Nov 2020-Feb 2025) and 15 TART (Mar 2022-Feb 2025). TART used da Vinci Surgical system (da Vinci) Xi for early cases and predominantly da Vinci SP thereafter. Indications included differentiated cancer ≤4 cm, cN0, unilateral disease without extrathyroidal invasion, or follicular tumors 3-5 cm. Operative time, blood loss, hospital stay, complications, and cosmetic outcomes were evaluated and compared with statistical analysis.

RESULTS: All procedures were completed without conversion to open surgery. Blood loss (16.5 g vs 25.8 g) and length of stay (6.3 vs 6.1 days) were comparable. Complications included two transient recurrent laryngeal nerve palsies after VANS and, after TART, one axillary bleed controlled under local anesthesia and one lymphatic leak; overall rates were similar. High cosmetic satisfaction was reported in both cohorts.

CONCLUSION: Early experience shows TART is feasible and safe in Japan, achieving perioperative outcomes comparable to VANS with excellent cosmetic results.
