ABSTRACT

OBJECTIVES: To evaluate the diagnostic accuracy of salivary gland ultrasound (SGUS) in patients with high suspicion of Sjögren’s Disease (SjD) and to determine its potential role in the diagnostic process.

METHODS: This study is a cross-sectional diagnostic trial based on a prospective cohort, including 171 patients with high suspicion of SjD. SGUS of the parotid glands (PG) and submandibular glands (SMG) was performed according to the OMERACT scoring system. The predictive value of SGUS for diagnostic outcomes and labial salivary gland biopsy (LSGB) results was analyzed. The correlation between SGUS grading and unstimulated salivary flow rates (USFR) was also assessed using statistical tests.

RESULTS: Of the 171 participants, 130 were diagnosed with SjD. The OMERACT total score demonstrated moderate efficacy in diagnosing SjD, with an area under the curve (AUC) of 0.78, a sensitivity of 0.52, and a specificity of 0.93. In comparison, LSGB showed the highest diagnostic efficacy (AUC = 0.90), followed by anti-Ro/SSA antibodies (AUC = 0.79). Combining the OMERACT total score with either anti-SSA antibodies or LSGB significantly improved diagnostic performance, achieving a specificity of 1.00. The diagnostic accuracy of parotid gland (PG) and submandibular gland (SMG) ultrasound grading was comparable. However, SMG grading exhibited higher sensitivity but lower specificity than PG grading. Additionally, SGUS grade 3 strongly predicted positive biopsy results (AUC = 0.77) and showed a significant correlation with USFR, with Spearman correlation coefficients of -0.45 for PG and -0.51 for SMG.

CONCLUSION: Although the discriminatory efficacy of SGUS in patients highly suspected of SjD is suboptimal, SGUS may offer significant benefits for a specific subgroup of these patients. Grade 3 ultrasound findings are strongly associated with positive biopsy results and USFR, indicating a potential role in diagnosis and disease evaluation. SGUS may be considered for inclusion in future SjD classification criteria.

ABSTRACT

BACKGROUND: Non-adherence to antiretroviral therapy (ART) among pregnant women poses significant challenges to effective Immunodeficiency Virus (HIV) treatment outcomes and the promotion of maternal and infant health. This study identifies factors influencing ART non-adherence among HIV-positive pregnant women attending public health facilities in Dessie Town, Ethiopia.

METHODS: A facility-based case-control study was conducted with 278 participants across health institutions in Dessie Town, comprising 208 controls and 70 cases. Non-adherence to ART was assessed using the 8-item Morisky Medication Adherence Scale (MMAS-8. Data were collected through structured interviewer-administered questionnaires and by reviewing patients’ medical records using pretested instruments. The collected data were coded and entered into EpiData version 4.6, then analyzed using SPSS version 25. Variables with a P-value of 0.2 in Bivariable analysis were included in a multivariable regression model, and Adjusted Odds Ratios (AOR) with 95% confidence intervals (CI) were calculated. P-values less than 0.05 were considered statistically significant.

RESULTS: In total, 208 controls and 70 cases were included in the study. Significant factors determining non-adherence to ART among HIV-positive pregnant women included forgetfulness to take ART (AOR = 2.414, 95% CI = 1.067-5.464, P = 0.034), non-disclosure (AOR = 2.955, 95% CI = 1.431-6.103, P = 0.003), an unplanned pregnancy (AOR = 3.045, 95% CI = 1.439-6.445, P = 0.004), those who did not participate in mother-support groups (AOR = 3.278, 95% CI = 1.611-6.672, P = 0.001), World Health Organization (WHO) clinical stages III & IV (AOR = 2.669, 95% CI = 1.279-5.569, P = 0.009), and those who did not take opportunistic infection prophylaxis (AOR = 3.873, 95% CI = 1.549-9.688, P = 0.004).

CONCLUSIONS: Key determinants included forgetfulness, non-disclosure of HIV status, unplanned pregnancies, lack of participation in mother-support groups, advanced WHO clinical stages (III & IV), and non-use of opportunistic infection prophylaxis.

RECOMMENDATIONS: All relevant parties, including front-line healthcare professionals, should advise women to use family planning more frequently to reduce unintended pregnancies. They should also encourage health education regarding disclosing HIV status to her spouse and ensure that all pregnant women are provided with opportunistic infection prophylaxis.

ABSTRACT

BACKGROUND: Boars undergo physiological and biochemical changes in semen composition as they grow from puberty to sexual maturity. However, comprehensive metabolomic profiles of boar semen remain uncharacterised. Understanding metabolic alterations in semen during this period is important for optimising reproductive performance in breeding programs. The aim of this study was to characterise the semen metabolome as boars mature, utilising an untargeted metabolomic approach. Semen samples were collected from 15 Duroc boars at three developmental ages: ~ 7 months, 8.5 months, and 10 months. Sperm and seminal plasma were separated and analysed by hydrophilic interaction and reversed-phase liquid chromatography coupled with mass spectrometry to capture a wide range of metabolites.

RESULTS: We identified a total of 4,491 features in boar semen, annotating 92 distinct metabolites. Amino acids, peptides and analogues constituted the most abundant components, followed by fatty acid esters. Principal component analysis (PCA) and partial least squares discriminant analysis (PLS-DA) showed a clear separation between metabolomic profiles by age groups. PERMANOVA analysis of PCA scores confirmed statistically significant differences (P < 0.05) between younger (7 months) and more mature boars (8.5 months and 10 months). Pathway analysis identified porphyrin metabolism, taurine and hypotaurine metabolism, and glycerolipid metabolism as significantly enriched pathways in sperm, while glutathione and nitrogen metabolism were prominently enriched in seminal plasma. Using linear modelling, partial Spearman correlation and random forest analyses, we identified homoisovanillic acid as a key metabolite discriminating age groups in both sperm and seminal plasma. Additionally, L-glutamic acid, decanoyl-L-carnitine and N-(1,3-Thiazol-2-yl)benzenesulfonamide emerged as important sperm metabolites, while glyceric acid, myo-inositol, glycerophosphocholine, and several other compounds were identified as critical seminal plasma metabolites.

CONCLUSION: This study provides a detailed characterisation of metabolic changes in Duroc boar semen during the transition from puberty to sexual maturity. Our findings enhance the understanding of reproductive development and could inform strategies to assess sexual maturity in breeding programs.

ABSTRACT

BACKGROUND: Mental health disorders, including depression, anxiety, and pain, are prevalent among ambulatory patients. Nurse-Led Education and Telehealth interventions have emerged as promising approaches to improving mental health outcomes. However, their comparative effectiveness remains unclear, particularly in Saudi Arabia.

AIM: This study compares the impact of Nurse-Led Education and Telehealth interventions on mental health outcomes (depression, anxiety, and pain) for ambulatory patients in Saudi Arabia.

METHODS: A quasi-expremintal study with pre and post tests were conducted with 400 participants, who were recruited through purposive sampling and assigned to receive either Nurse-Led Education or Telehealth interventions over eight weeks. Depression, anxiety, and pain were measured using the PHQ-9, STAI, and VAS tools, respectively. Data were analyzed using descriptive statistics, independent t-tests, logistic regression, and Structural Equation Modeling (SEM), with anxiety examined as a potential mediator.

RESULTS: Both the Nurse-Led Education and Telehealth Intervention groups showed significant improvements in mental health outcomes, including reductions in depression (PHQ-9), anxiety (STAI), and pain (VAS). The Nurse-Led Education group improved from 20.3 to 12.4 in PHQ-9, while the Telehealth group decreased from 21.8 to 15.2, both with p < 0.001. Pain scores also decreased significantly in both groups, with the Nurse-Led group improving from 18.9 to 9.3 and the Telehealth group from 31.3 to 18.5 (p < 0.001). Anxiety levels decreased in both groups (p < 0.001). Regression analysis indicated that Telehealth had a stronger association with improvements across all outcomes, with anxiety playing a significant mediating role in the Telehealth group. Structural Equation Modeling (SEM) further demonstrated that Telehealth had a more pronounced effect on pain management and mental health outcomes, highlighting its potential for more robust results compared to Nurse-Led Education, though both interventions proved beneficial.

CONCLUSION: Telehealth interventions showed superior efficacy in managing depression and pain, potentially due to individualized care. Nurse-Led Education excelled in fostering peer support, which equally benefited anxiety management. These findings highlight the importance of tailored approaches in mental health care.

CLINICAL TRIAL: No clinical trial.

ABSTRACT

INTRODUCTION: Late requests for safe abortion during the second trimester are strongly associated with severe maternal complications, including infertility, preterm birth, low birth weight, and maternal mortality, especially in developing countries. These delays also contribute to adverse pregnancy outcomes beyond direct maternal deaths. Despite these serious concerns, data on the prevalence and contributing factors of late abortion requests in Ethiopia remain limited.

OBJECTIVE: To estimate the pooled prevalence of late requests for safe abortion and identify the determinants among Ethiopian women of reproductive age.

METHODS: This systematic review and meta-analysis was conducted following the PRISMA 2020 guidelines. A comprehensive search was performed across major international databases, including PubMed, Cochrane Library, Google Scholar, Hinari, Scopus, Web of Science, and African Journals Online, using the CoCoPop strategy. Study quality was assessed using the Joanna Briggs Institute (JBI) tool. Heterogeneity among studies was evaluated with the I² statistic, and publication bias was assessed using funnel plots and Egger’s test. A random-effects model was employed to estimate the pooled prevalence and adjusted odds ratios (AOR) with 95% confidence intervals (CI).

RESULTS: Ten studies involving a total of 5,559 women were included. The pooled prevalence of late requests for safe abortion was 35.20% (95% CI: 26.21, 44.19). Significant determinants identified were delayed pregnancy diagnosis (AOR: 3.23; 95% CI: 2.52, 4.13), irregular menstrual cycles (AOR: 2.36; 95% CI: 1.86, 3.00), rural residence (AOR: 2.89; 95% CI: 2.34, 3.58), unmarried status (AOR: 2.86; 95% CI: 2.13, 3.86), and age under 19 years (AOR: 4.01; 95% CI: 2.41, 6.67).

CONCLUSION: Late requests for safe abortion are common in Ethiopia and are influenced by factors such as rural residence, young age, delayed recognition of pregnancy, and irregular menstrual cycles. Enhancing access to reproductive health services especially for rural and adolescent populations is essential to reduce maternal complications and promote timely care.

ABSTRACT

OBJECTIVE: This study aimed to investigate the efficacy of endovascular embolization in treating ruptured intracranial aneurysms (RIAs).

METHODS: RIA patients (n = 89) were grouped according to different surgical methods. The control group (n = 42) received aneurysm clipping surgery, whereas the observation group (n = 47) received endovascular embolization. The National Institutes of Health Stroke Scale (NIHSS) was used to assess neurological function pre-treatment and at 7 days post-treatment. Oxidative stress status, including superoxide dismutase (SOD) levels and serum malondialdehyde (MDA) levels, was compared between the two groups pre-treatment and at 7 days post-treatment. Intraoperative bleeding, operative time, and hospitalization time were compared between the two groups. Vascular endothelial function, including von Willebrand factor (vWF), endothelin-1 (ET-1), and nitric oxide (NO), was evaluated pre-treatment and 3 months post-treatment. Postoperative complications and surgical outcomes were observed.

RESULTS: After treatment, compared to the control group, the observation group had lower NIHSS scores, higher SOD levels, and lower MDA levels, with statistically significant differences (all P < 0.001); the observation group also had less intraoperative bleeding, shorter operation times, and shorter hospital stays, along with lower vWF and ET-1 levels, higher NO levels, and statistically significant differences (all P < 0.001). The incidence of postoperative complications was lower in the observation group, with a statistically significant difference (P = 0.048). The therapeutic effect was better in the observation group, with a statistically significant difference (P = 0.041).

CONCLUSION: Compared with microscopic aneurysm clipping, endovascular embolization offers better efficacy for patients with RIA and causes less vascular endothelial damage.

ABSTRACT

INTRODUCTION: Since 1970, monkey-pox, the last outbreak of smallpox, coronavirus was outbreak in the world for more than 50 years. To find if the outbreak dates could be predicted by their one-dimension protein sequence, the mathematical model was needed to establish between them.

METHODS: (A) collecting the outbreak dates of monkey-pox, smallpox, and coronavirus, determine the outbreak time interval between the pathogen strain and the reference strain SARS-CoV-2 D614, z. (B) detecting the one-dimension antigenic amino acid sequence of the pathogen strain to determine the super-antigens. (C) calculating the super-antigen precision, determining the increase amount in antigen precision between the pathogen strain and the reference strain, x; y represents the number of tryptophan (W) in the super-antigen. (D) Determine the correlation among the outbreak time interval z, the increase amount in antigen precision, x, and the number of W the super-antigen contains, y.

RESULTS: The regression equation is z = 13.762x² – 109.376x- 63.290y + 221.197, with a correlation coefficient of R = 1.0000000. After statistical testing, the probability of class I errors occurring is P = 0.008.

CONCLUSIONS: The method can predict the outbreak dates by one-dimension protein sequence, such as monkey-pox, smallpox, and coronavirus.

ABSTRACT

BACKGROUND: This study investigates acute malnutrition among children aged 6-59 months in conflict-affected districts of western Ethiopia. It addresses the lack of localized data by examining the prevalence and key contributing factors, including maternal health, child feeding practices, and healthcare access. Findings aim to inform targeted, multisectoral interventions to improve child nutrition in similar crisis-affected settings.

METHOD: A community-based cross-sectional study was conducted from June 1 to July 1, 2024, involving 513 children aged 6-59 months. A proportionate sample was selected from each Woreda using systematic sampling, with one child randomly chosen from households with multiple eligible children. Trained enumerators collected data using a pre-tested questionnaire, and nutritional status was assessed using mid-upper arm circumference (MUAC) measurements. Data were entered into Epi-data version 3.1 and exported to SPSS version 25.0 for analysis. Descriptive statistics were performed, followed by bivariable and multivariable logistic regression to identify factors associated with acute malnutrition, with statistical significance declared at P-value < 0.05.

RESULTS: A total of 498 participants were included within the study with a response rate of 97%. The largest proportions (44.4%) were aged 24-59 months. Acute malnutrition prevalence was 20.7% [17.1% to 24.3%] with 6.2% having severe malnutrition and 14.5% moderate. Key risk factors for acute malnutrition included food insecurity with (AOR: 1.81, 95% CI: 1.03-3.17), pre-lacteal feeding (AOR: 2.01, 95% CI: 1.09-3.68), maternal malnutrition (AOR: 4.11, 95% CI: 2.40-7.05), less than four antenatal visits of current child pregancy (AOR: 3.94, 95% CI: 1.64-9.45), and bottle-feeding (OR: 2.79, 95% CI: 1.51-5.14).

CONCLUSION AND RECOMMENDATION: The severe burden of acute malnutrition demands immediate, comprehensive action. An integrated approach is essential, emphasizing improved access to nutritious food, strengthened maternal and child health services, and increased caregiver awareness. Key strategies include merging maternal and child health initiatives, encouraging exclusive breastfeeding, ensuring regular antenatal care, and promoting appropriate infant feeding. Together, these efforts can play a crucial role in lowering acute malnutrition rates and enhancing child health in the community.

ABSTRACT

Currently, no suitable parameter to predict the occurrence of azotaemic chronic kidney disease (CKD) after hyperthyroidism treatment in cats exists. The aim of this study was to evaluate various clinical and laboratory parameters as well as renal cortical thickness (assessed by ultrasound) as predictors of azotaemic CKD after radioiodine therapy (RAIT).Cats presented for RAIT (April 2021-April 2022) were prospectively enrolled. Cats with azotaemia (creatinine≥140 µmol/L) and cats with pathological renal morphology were excluded. After RAIT, cats were followed for 6-12 months (measurement of total thyroxine [TT4], thyroid-stimulating hormone and creatinine). Cats with persistent hyperthyroidism and cats with a follow-up<6 months were excluded from the statistical analysis, as their thyroid and kidney function could not be sufficiently evaluated. Following parameters obtained prior RAIT were compared between cats that developed azotaemic CKD following RAIT and those that did not: age, weight, duration since the diagnosis of hyperthyroidism and RAIT, blood pressure, haematocrit, concentration of creatinine, urea, potassium, phosphate, TT4 and symmetrical dimethylarginine, urine-specific gravity, urine protein/creatinine ratio and sonographically assessed renal cortical thickness.51 cats were enrolled; 29/51 were included in the statistical analysis (11/29 became euthyroid and 18/29 became hypothyroid post RAIT). There was no difference in the frequency of azotaemia between euthyroid and hypothyroid cats (5/11 vs. 6/18, p=0.7). None of the clinical, laboratory and morphological markers proved to be predictive of the development of azotaemic CKD following RAIT.None of the investigated parameters was predictive of the development of azotaemic CKD in hyperthyroid cats after RAIT. Due to the small study population, future larger studies should be undertaken, especially to assess morphological markers.

ABSTRACT

In South American Camelids (SAC), determining a suitable time point for mating poses challenges as females ready for conception do not show estrus signs or behavioral changes. Therefore, the applicability of measuring sex steroids in milk and vaginal cytology as non-invasive methods for monitoring ovarian activity was investigated.Samples were collected from a total of 10 alpacas (A) and 9 llamas (L) over a period of 4 weeks following parturition. The concentrations of progesterone (P4), estradiol-17β (E2) and total estrogens (GOE) in blood and milk were measured using radioimmunoassays after sample extraction. Vaginal swabs were prepared and evaluated according to the procedure routinely used in dogs.In A and L, the estrogen concentrations in milk were significantly lower than those in blood (E2 in blood: A: 11.1±2.9 pg/ml, L: 14.6±5.0 pg/ml; E2 in milk: A: 6.2±3.1 pg/ml, L: 7.9±5.8 pg/ml; GOE in blood: A: 120. 2±26.9 pg/ml, L: 143.7±45 pg/ml; GOE in milk: A: 57.1±16.1, L: 75.9±34.6 pg/ml), while the differences between the two species were not significant. The correlations between steroid concentrations in blood and milk were statistically significant in L, but not in A. While in L, correlations between estrogen concentrations and vaginal cytological parameters showed several statistical significances with p-values partly <0.01, in A only GOE in the blood was negatively correlated with the proportion of basal-/parabasal cells.P4 measurement in milk allows the detection of luteal phases in SAC with high reliability. Despite statistical significance, the correlations between estrogen concentrations in blood and milk were also too weak in L to estimate blood concentrations with acceptable accuracy based on estrogen concentrations in milk at the level of the individual animal. Vaginal cytology could in principle be suitable for the identification of the maturation phase of follicular waves in L. However, improvements of the methodology and further validation are warranted before its routine use.
