ABSTRACT

BACKGROUND: Measles remain a significant public health concern, especially in Botswana, where sporadic and silent epidemics continue to challenge existing control measures. This study aimed to determine the health system and caregivers related factors influencing measles vaccine uptake.

METHODS: A cross-sectional study was conducted between September and October 2024 in Chadibe village. The facility registers served as the data source and the study analyzed information from 201 under-fives records with a follow up caregivers questionnaire used to capture information on sociodemographic variables and health system related factors. Statistical analysis involved frequencies, bivariate and multivariate logistic regression.

RESULTS: Our study revealed that 82.6% of children received first dose of measles vaccine, while 50.2% received the second dose. Both figures are lower than the WHO target. The key determinants related to two doses of measles vaccination include care giver characteristics and health system related. Caregivers aged 18-25 years (OR: 4.42; 95% C.I: 1.22-16.00, P = 0.023), 26-30 years (OR: 1.71; 95% C.I: 0.59-4.94) and 31-35 years of age (OR: 2.74; 95% C.I: 1.026-7.36) were more likely to get their children immunized. Care givers who walked to the health facility (OR: 2.28;95% CI:0.86-6.00), used public transport (OR:1.94; 95% CI 0.74-5.06) found vaccine to be always available (OR 12.8;95%CI: 2.24-73.92, P 0.004) sometimes available (OR 7.09;95% CI: 1.45-34.60, P0.01) were associated with the likelihood to have their children fully vaccinated. On multivariate analysis, caregivers who completed senior secondary education (AOR: 6.59; 95% CI: 1.02-7.36, P = 0.01), working full time (AOR = 1.77, 95% CI: 0.64-4.92) travelled less than 5 km to the health facility (AOR: 3.47;95% CI: 1.49-8.10, P = 0.004), received fairly good quality of service (AOR:2.20; 95% CI: 1.02-4.73, P = 0.043) had measles vaccine information (AOR = 3.97, CI = 1.455-10.85,P = 0.007) were also more likely to immunize their children.

CONCLUSION: The complete dose of measles vaccination rate in Chadibe is still low compared to the first dose of measles vaccination and global target. This study provides valuable insights into the epidemiology of the Measles vaccination. The low vaccination uptake highlights the urgency of raising awareness about vaccine importance and strengthening routine immunization programs.

ABSTRACT

BACKGROUND: Physically active persons frequently change their dietary intakes to get the best results in their exercises. These changes in dietary intakes, which are not healthy in some cases, might influence the risk of psychological disorders in them. In the present study, we investigated the association between adherence to the MIND diet and the odds of depression, anxiety, and sleep disturbances among physically active adults.

METHODS: A total of 684 participants were included in this cross-sectional study. Dietary intakes of study participants were assessed using a validated 168-item semi-quantitative Food Frequency Questionnaire (FFQ). The MIND diet score was calculated based on participants’ dietary intakes obtained from FFQ. To assess depression, anxiety, and sleep quality, the Beck Depression Inventory II (BDI-II), the Beck Anxiety Inventory (BAI), and the Pittsburgh Sleep Quality Index (PSQI) were used, respectively. All statistical analyses were conducted using SPSS (SPSS Inc., version 18).

RESULTS: After adjusting for the potential confounding factors, participants at the top tertile of MIND diet score were 51% less likely to have depression compared with those at the bottom tertile (OR: 0.69, 95% CI: 0.18, 0.90). We found no significant association between the MIND diet score and odds of anxiety (OR: 1.17; 95% CI: 0.71, 1.95) and sleep disturbances (OR: 1.25; 95% CI: 0.86, 1.81).

CONCLUSION: Our findings showed that more adherence to the MIND diet might be negatively associated with the odds of depression in physically active adults. No such significant association was found for the odds of anxiety or sleep disturbances. More studies are warranted.

ABSTRACT

OBJECTIVE: Heterogenous results were reported in the effects of hypoglycemia in pregnancy. This study evaluated pregnancy outcomes in women with hypoglycemia during the antenatal 75-gram oral glucose tolerance test (OGTT).

METHODS: OGTT results of the mothers of all live-born delivered in a tertiary obstetrics centre were evaluated between Jan 2021 and June 2022. All patients had OGTT at 26-30th weeks of gestation. Hypoglycemia was defined as any low plasma glucose ≤ 3.5mmol/L on OGTT. Maternal and neonatal outcomes were compared among the four groups; normal results (group 1), hypoglycemia in OGTT (group 2), gestational diabetes mellitus (GDM) (group 3) and pregestational diabetes mellitus (DM) (group 4).

RESULTS: There were 3715 women delivered within the study period and 3164 (85.2%) had normal results. 65 (1.7%) women had hypoglycemia, 464 (12.5%) women had GDM and 22 (0.6%) women had pregestational DM. None of the Group 2 patients were symptomatic. Maternal demographics were comparable. Patients with hypoglycemia during OGTT were not at an increased risk of preterm delivery (1.5% vs. 2.8%, p = 0.86). There was no statistical difference in the incidence of Caesarean Sect. (32.3% vs. 34.4%, p = 0.54), postpartum haemorrhage (10.8% vs. 14.7% p = 0.28). Women with hypoglycemia during OGTT were not at risk of adverse outcome in terms of neonatal intensive care unit admission (16.9% vs. 8.5%, p = 0.28) and Apgar score at 5th minute of life (9.8 vs. 9.8, p = 0.17).

CONCLUSION: Hypoglycemia in antenatal OGTT is not associated with adverse neonatal or maternal outcomes. It is likely to resolve after delivery.

ABSTRACT

BACKGROUND: The clinical heterogeneity observed in chronic lymphocytic leukemia (CLL) is largely attributed to diverse underlying genomic alterations. Fluorescence in situ hybridization (FISH) remains the standard cytogenetic technique but is limited to predefined loci. As a genome-wide approach, optical genome mapping (OGM) facilitates the identification of structural variants (SVs), such as copy number variations (CNVs), offering a broader genomic perspective. This study was designed to compare the findings of FISH and OGM in a cohort of CLL patients. By integrating these two cytogenetic approaches, we sought to evaluate the potential of OGM in detecting additional or cryptic genomic alterations that may impact prognosis and therapeutic decision-making.

METHODS: Twenty newly diagnosed or treatment-naive CLL patients were analyzed using both FISH and OGM. SVs, CNVs, and chromosomal abnormalities were compared across methods. Concordance and discordance were evaluated, and OGM-specific alterations were examined for clinical relevance. Statistical analysis was performed using IBM SPSS Statistics for Windows, Version 26.0. Given the limited sample size (n=20), only descriptive statistics were applied. Frequencies and percentages were used to summarize categorical variables, while continuous variables were expressed as median and range.

RESULTS: The cohort had a median age of 61.5 years (range: 44-83), with 60% male. No abnormalities were detected by either method in 2 patients. Among the remaining 18 patients OGM revealed 22 SVs, 32 CNVs, and 8 aneuploidies. In 3 patients, FISH results were negative, whereas OGM identified various abnormalities.

CONCLUSIONS: According to our results OGM identified additional chromosomal abnormalities not covered by the FISH panel in three of our patient cohort out of the five patients in whom FISH analysis had not detected any abnormalities, highlighting the potential to reshape prognostic algorithms in CLL. Our data emphasize the utility of OGM as a valuable adjunct to standard cytogenetic assessment.

ABSTRACT

BACKGROUND: Interferon-gamma release assays (IGRAs) are widely used for detecting latent tuberculosis infection (LTBI). However, these tests can yield indeterminate results, posing challenges for clinical management. The management of these indeterminate outcomes varies, creating uncertainty in clinical practice. This study systematically evaluates the effectiveness of repeat IGRA testing versus additional tuberculin skin testing (TST) in resolving indeterminate IGRA results during LTBI screening.

METHODS: We conducted a systematic review and meta-analysis, searching PubMed, Embase, Web of Science, and the Cochrane Library databases on May 18, 2024, without start date or language restrictions. Studies were included if they screened for LTBI in healthy or high-risk populations using IGRA, reported indeterminate results, and managed these results with repeat IGRA testing and/or additional TST. A random-effects model was used to calculate pooled results.

RESULTS: A total of 59 studies were included in this analysis. Among these, 40 studies assessed the use of additional TST in individuals with indeterminate IGRA results, yielding a pooled confirmation rate of 98.6% (95% CI: 96.2-99.8%). Additionally, 27 studies examined repeat IGRA testing, which resulted in a pooled confirmation rate of 68.9% (95% CI: 57.0-79.6%). Furthermore, eight studies evaluated both TST and repeat IGRA testing, with the pooled confirmation rate for the TST being 93.7% (95% CI: 78.7-99.9%), higher than the pooled confirmation rate for repeat testing at 76.5% (95% CI: 44.6-97.1%). However, there was no statistically significant difference in the confirmation rates between the two testing methods (OR = 2.13, 95% CI: 0.47-9.76).

CONCLUSIONS: In managing indeterminate IGRA results during LTBI screening, head-to-head studies show no significant difference in confirmation rates between additional TST and repeat IGRA. Across nearly 60 studies, additional TST tends to have a slightly higher confirmation rate, though the difference is not statistically significant. Clinically, for patients with an initial indeterminate IGRA who are immunocompetent, with convenient sample collection or a need for rapid results, additional TST may help achieve more reliable outcomes. Selection of follow-up testing should consider the cause of indeterminate results, feasibility, and risk of patient loss to follow-up.

ABSTRACT

PURPOSE: Artificial intelligence (AI) has become incredibly popular over the past several years, with large language models (LLMs) offering the possibility of revolutionizing the way healthcare information is shared with patients. However, to prevent the spread of misinformation, analyzing the accuracy of answers from these LLMs is essential. This study will aim to assess the accuracy of five freely accessible chatbots by specifically evaluating their responses to questions about patellofemoral instability (PFI). The secondary objective will be to compare the different chatbots, to distinguish which LLM offers the most accurate set of responses.

METHODS: Ten questions were selected from a previously published international Delphi Consensus study pertaining to patellar instability, and posed to ChatGPT4o, Perplexity AI, Bing CoPilot, Claude2, and Google Gemini. Responses were assessed for accuracy using the validated Mika score by eight Orthopedic surgeons who have completed fellowship training in sports-medicine. Median responses amongst the eight reviewers for each question were compared using the Kruskal-Wallis and Dunn’s post-hoc tests. Percentages of each Mika score distribution were compared using Pearson’s chi-square test. P-values less than or equal to 0.05 were considered significant. The Gwet’s AC2 coefficient was calculated to assess for inter-rater agreement, corrected for chance and employing quadratic weights.

RESULTS: ChatGPT4o and Claude2 had the highest percentage of reviews (38/80, 47.5%) considered to be an “excellent response not requiring classification”, or a Mika score of 1. Google Gemini had the highest percentage of reviews (17/80, 21.3%) considered to be “unsatisfactory requiring substantial clarification”, or a Mika score of 4 (p < 0.001). The median ± interquartile range (IQR) Mika scores was 2 (1) for ChatGPT4o and Perplexity AI, 2 (2) for Bing CoPilot and Claude2, and 3 (2) for Google Gemini. Median responses were not significantly different between ChatGPT4o, Perplexity AI, Bing CoPilot, and Claude2, however all four statistically outperformed Google Gemini (p < 0.05). Inter-rater agreement was classified as moderate (0.40 > AC2 ≥ 0.60) for ChatGPT, Perplexity AI, Bing CoPilot, and Claude2, while there was no agreement for Google Gemini (AC2 < 0).

CONCLUSION: Current free access LLMs (ChatGPT4o, Perplexity AI, Bing CoPilot, and Claude2) predominantly provide satisfactory responses requiring minimal clarification to standardized questions relating to patellar instability. Google Gemini statistically underperformed in accuracy relative to the other four LLMs, with most answers requiring moderate clarification. Furthermore, inter-rater agreement was moderate for all LLMs apart from Google Gemini, which had no agreement. These findings advocate for the utility of existing LLMs in serving as an adjunct to physicians and surgeons in providing patients information pertaining to patellar instability.

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.
