ABSTRACT

BACKGROUND AND OBJECTIVES: Blood transfusion is a vital medical procedure, yet it carries the risk of transmitting infectious diseases. This study aimed to assess the demographic characteristics and transfusion-transmitted infection (TTI) profiles of family replacement and voluntary blood donors in Saudi Arabia.

MATERIALS AND METHODS: A retrospective cross-sectional analysis was conducted using records from 49,590 blood donors at King Fahad Medical City, Riyadh, Saudi Arabia. Donors were classified as family replacement or voluntary. Demographic information and results of screening for hepatitis B virus (HBV), hepatitis C virus (HCV), human immunodeficiency virus (HIV), syphilis, and malaria were analysed. Statistical analyses included descriptive statistics, chi-square testing, stratified analysis by nationality, and logistic regression.

RESULTS: 49,590 donors were included, 10.6% were family replacement and 89.4% were voluntary. Males accounted for 92.6% of the donor population. No significant differences were observed between the two groups for HBV, HCV, HIV, or syphilis. However, malaria prevalence was significantly higher among family replacement donors (5.3%) compared to voluntary donors (2.9%). Family replacement donation was more common among younger donors, males, and non-Saudi nationals.‏ The higher malaria prevalence among family replacement donors was particularly evident among non-Saudi donors, and regression analysis confirmed that nationality modified the association between donation type and malaria positivity.

CONCLUSION: While rates of major viral TTIs were comparable between donor types, malaria risk was significantly higher among family replacement donors, especially among non-Saudi donors. These findings highlight the importance of continued malaria screening and donor selection strategies to maintain safe blood transfusion practices in Saudi Arabia.

ABSTRACT

AIM: Nausea and vomiting in pregnancy impact quality of life, yet many pregnant women feel dismissed by healthcare professionals, despite the safety of first-line antiemetic treatments for both mother and fetus. Therefore, this study aims to describe the prevalence of patient-reported antiemetic use in early pregnancy in Copenhagen, Denmark, the changes in use over two time periods, and the maternal characteristics of users and non-users.

METHODS: We analysed patient-reported data on antiemetic use during early pregnancy and maternal characteristics from the Copenhagen Pregnancy Cohort (2012-2022). Descriptive statistics were applied to assess the prevalence, changes in use over two time periods and differences between users and non-users.

RESULTS: Among 40 856 pregnancies, 1.0% (n = 412) reported using antiemetics in early pregnancy. Metoclopramide was the most used, reported by 0.2% (n = 93). The number of pregnancies with patient-reported antiemetic use doubled from 0.7% in 2012-2017 to 1.4% in 2018-2022. Among users, 83.3% received monotherapy, and 74.1% used antiemetics daily. Compared with non-users, a significantly higher proportion of antiemetic users scored <50 on the World Health Organization Five Well-Being Index (66.6% vs. 20.5%, p < .001) and to a higher extent reported sick leave (68.0% vs. 14.1%, p < .001).

CONCLUSION: We found a low but rising prevalence of antiemetic use in early pregnancy, and the treatment often deviated from clinical guidelines. Antiemetic users differed from non-users on several maternal characteristics, with a higher proportion reporting somatic and psychiatric disorders, as well as poorer mental well-being, despite antiemetic treatment.

ABSTRACT

OBJECTIVE: Many people with rheumatoid arthritis (RA) have chronic pain and flares of arthritis. The National RA Society has co-produced a freely available online learning module with an NHS multidisciplinary rheumatology team to support people with self-managing these RA impacts. This service evaluation assessed peoples’ self-reported knowledge and confidence in self-managing pain/flares before and after accessing the module, the extent to which they used the module suggestions, and how they felt the module could be improved.

METHODS: A survey was sent via email in March 2024 to the 500 people completing the module who consented to contact for feedback. Survey questions covered: pain experience/management; knowledge/confidence on managing pain/flares; likelihood of trying module suggestions; and free-text feedback. Descriptive statistics summarised responses. Fisher’s exact tests compared Likert-type responses for knowledge/confidence pre-/post-module.

RESULTS: One hundred and thirty four people completed the survey (27% response rate), of whom 98% experienced pain in the past 3 months and 36% reported ‘high impact’ chronic pain. More (95%) reported being ‘very/fairly/somewhat’ knowledgeable at managing pain after completing the module compared to before completing the module (62%; p < 0.01). For managing flares, these levels were 93% post-module versus 52% pre-module (p < 0.01). Similar findings were seen for confidence. 90% reported themselves as ‘very/fairly/somewhat’ confident at managing pain post-module versus 50% pre-module (p < 0.01). For managing flares, these levels were 90% post-module versus 44% pre-module (p < 0.01). Most reported they were likely to try module suggestions.

CONCLUSIONS: This freely available online digital information about pain/flares was appreciated by people with RA and helped them deal with these common condition aspects.

ABSTRACT

BACKGROUND: Lipodystrophy syndromes (LD) are a group of rare conditions characterised by the generalised or partial absence and/or dysfunction of adipocytes. Due to the lack of fat storage capacity, excess lipid accumulates in other tissues, leading to severe insulin resistance. At present, effective therapeutic options remain limited, with metreleptin currently the only specific licensed treatment. To this end, we evaluated the therapeutic impact of tirzepatide in people with partial lipodystrophy (PLD).

METHODS: This was a single-centre, retrospective, observational study, including all patients with PLD treated with tirzepatide between January 2022 and September 2025.

RESULTS: 40 patients with PLD were included (FPLD1 like =26 (65%), FPLD2 =4 (10%), FPLD3 =7 (17.5%), FPLD7=1 (2.5%), APLD=1 (2.5%), Unclassified=1 (2.5%)). 87.5% (n=35) were female with a median age of 47 years (IQR 39 – 59) and a median BMI of 31.5 kg/m2 (IQR 27.3 – 35.5). After a median 9.5 month follow-up (IQR 7 – 11), marked reductions were seen in body weight from 91.0kg (IQR 75.0 – 106.0) to 82.8kg (IQR 69.0 – 93.4; p<0.0001), in HbA1c from 65 mmol/mol (IQR 54.5 – 85) to 52 mmol/mol (IQR 39 – 62; p<0.0001) and in serum triglycerides from 2.80 mmol/L (IQR 1.6 – 3.7) to 1.83 mmol/L (IQR 1.0 – 2.9; P=0.0005). Daily insulin requirements fell from 177.5 IU (IQR 101.3 – 213.8) to 58.0 IU (IQR 0 – 112.5; P=0.0028).

CONCLUSION: In patients with partial lipodystrophy, tirzepatide use resulted in substantial statistically significant reductions in weight, glycaemic control, serum triglycerides and daily insulin requirement. We recommend further prospective studies to support these findings and to evaluate its impact earlier in the course of the disorder.

ABSTRACT

CONTEXT: BPA is a synthetic chemical used in consumer goods that has been linked to type 2 diabetes in observational studies. No human experimental studies have examined whether BPA reduces peripheral insulin sensitivity.

PURPOSE: To determine the effects of oral BPA administration on peripheral insulin sensitivity over 5 days.

METHODS: Forty sedentary, but otherwise healthy adults (22 F, 18 M; 21.3 ± 2.1 yr; 22.1 ± 2.3 kg/m2; 85% Non-Hispanic White) completed a 2-day baseline energy-balanced diet low in BPA during which urine, blood, and peripheral insulin sensitivity via 120 min euglycemic hyperinsulinemic clamp technique (40 mU/m2/min; 90 mg/dL) were assessed. In a double-blind fashion, participants were randomly assigned to receive 5 days of oral BPA administration at 50 μg/kg body weight (BPA-50) or placebo (PL). All participants were fed the same energy-balanced diet. Outcomes were assessed using a two-way repeated-measures ANOVA adjusted for baseline sex, BMI, physical activity, and ethnicity.

RESULTS: After treatment, urine BPA levels were significantly higher in BPA-50 compared to PL (+ 268,700 ± 63983 vs. PL: + 8893 ± 6786 pg/mL, P = 0.009). After treatment, body weight and fasting glucose were not statistically different between PL and BPA-50 (P > 0.05). However, BPA significantly decreased peripheral insulin sensitivity by 0.02 ± 0.01 mg/kg/min/uU/ml compared with an increase observed following PL by 0.02 ± 0.01 mg/kg/min/uU/ml (P = 0.01).

CONCLUSION: BPA administration decreased peripheral insulin sensitivity after 5 days. These data provide the first experimental evidence in humans that BPA administration may reduce insulin sensitivity.

ABSTRACT

Physicians require timely access to patient information to provide effective care. However, in Canada, most of this information is siloed in unconnected systems, limiting access at the point of care. This paper analyzes the current state of electronic access to and exchange of patient information among Canadian physicians, using data from the 2024 Infoway-Canadian Medical Association survey of physicians. Using descriptive analysis, the paper reveals an imbalance between the growing adoption of digital health solutions (notably electronic medical records and electronic health records) and advancements in interoperability. To achieve a more connected digital health ecosystem, the paper calls for policy efforts, data-sharing frameworks and incentive strategies.

ABSTRACT

BACKGROUND: Enhanced recovery after surgery (ERAS) protocols have demonstrated substantial benefits in improving postoperative outcomes. However, in low-resource settings such as Ethiopia, ERAS adoption remains limited, necessitating pragmatic context-sensitive implementation approaches. The perspectives of frontline perioperative providers who are central to implementation have rarely been systematically assessed. This study aimed to evaluate acceptance, perceived benefits, implementation challenges, and readiness for sustained adoption of a pragmatic triple enhanced recovery after surgery (T-ERAS) protocol, comprising early oral intake, early ambulation, and early urinary catheter removal, among healthcare workers participating in a multisite ERAS trial in Ethiopia.

METHODS: A descriptive cross-sectional survey was conducted among 20 perioperative care providers, including surgeons, obstetricians, anesthetists, and nurses, from five public hospitals involved in the ERAS implementation trial. A structured questionnaire administered via Google Forms captured demographic characteristics, ERAS knowledge and exposure, perceived benefits and challenges, and willingness to adopt ERAS practices. Data were analyzed using descriptive statistics and thematic summaries.

RESULTS: Twenty perioperative care providers participated, of whom 13 (65.0%) were male, and 15 (75.0%) were affiliated with tertiary-level public hospitals. Twelve respondents (60.0%) reported being very familiar with ERAS protocols, although only 11 (55.0%) had directly participated in implementation. Sixteen participants (80.0%) believed ERAS improves patient outcomes; however, adherence varied, with 8 (42.1%) reporting rarely applying the protocol. Key implementation challenges included limited resources (85.0%), insufficient staff training (70.0%), resistance to change (50.0%), and inadequate patient education (50.0%). Despite these barriers, 17 participants (85.0%) expressed willingness to adopt ERAS practices permanently, and all (100.0%) were open to further training. The T-ERAS components were viewed favorably, with 15 participants (75.0%) rating each as effective.

CONCLUSION: This study demonstrates high awareness and willingness among perioperative professionals in Ethiopian public hospitals to adopt ERAS principles, while highlighting persistent system-level barriers to consistent implementation. Strengthening institutional support, expanding training, and promoting locally led context-sensitive ERAS pathways such as T-ERAS may facilitate sustainable scale-up in low-resource settings.

ABSTRACT

BACKGROUND AND STUDY AIM: Bowel preparation is a crucial step in ensuring the success of pediatric colonoscopy. This study aimed to investigate the effects of adding Senna alkaloid syrup to laxative agents for bowel preparation in children scheduled for colonoscopy.

PATIENTS AND METHODS: This double- blind controlled trial study compared two bowel preparation methods in children attending the gastrointestinal ward at Namazee Hospital, affiliated with Shiraz University of Medical Sciences, Shiraz, Iran. The study was conducted in 2024. Eligible patients were randomized into two groups: one receiving conventional laxative agents and the other receiving conventional agents plus polyethylene glycol-3350 (PEG-3350) syrup. Efficacy was analyzed using the Aronchick Scale, alongside safety evaluations.

RESULTS: A total of 64 children completed the study: 32 patients (17 girls, 15 boys) in the Senna group and 32 patients (11 girls, 21 boys) in the control group. The mean age of participants was 11.03 ± 4.60 years (range: 1 to 18 years). There was a statistically significant difference in colon cleansing between the Senna group and the conventional group based on Aronchick Scale (p < 0.001). The Senna group had no children requiring repeat bowel preparation. No side effects were reported in either group.

CONCLUSION: These findings suggest that incorporating Senna into routine bowel preparation protocols may improve outcomes and could become standard practice for pediatric colonoscopy. (Clinical trial number: IRCT20250426065473N1).

ABSTRACT

Myocardial Perfusion Imaging is widely used to evaluate left ventricular perfusion in patients with ischemic heart disease. Semi-quantitative scores, such as Total Perfusion Deficit (TPD), are frequently used for the assessment of extent and severity of disease. TPD scores are based on a frequentist analysis of tracer distribution in perfusion polar maps, which are 2D polar representations of radiopharmaceutical tracer uptake in the left ventricular cardiac wall. In this paper, we propose a novel quantification method for MPI examinations. Our method approaches the problem from an inverse perspective to TPD, allowing the assessment of the severity and extension of abnormal perfusion from the synergetic contribution of all the left ventricular tracer uptake in a polar map. We analytically demonstrate that TPD can be viewed as a specific instance of a broader approach. Furthermore, we explore how to establish the quantitative analysis in a general approach. To test our new method, we leveraged a standard deep learning architecture for the prediction of abnormal perfusion and used gradient-based class activation maps as a measure of the abnormal perfusion territory, which facilitated the quantification of both the severity and extent of the perfusion deficit. In the absence of ground-truth data such as survival rates or major adverse cardiovascular events (MACE) criteria, our results demonstrate both statistical and visual consistency with the conventional TPD.

ABSTRACT

Objective: To investigate the association between baseline cumulative atherogenic index of plasma and the risk of new-onset cardiovascular disease in middle-aged and young populations. Methods: A total of 35 212 populations under 60-years old with complete physical examination in 2006 and 2010 from the Kailuan Study were retrospectively enrolled. Complete atherogenic index of plasma data were extracted and populations were grouped by cumulative atherogenic index of plasma quartile: Q1 group (<-0.80, n=8 803), Q2 group (-0.80-<-0.19, n=8 803), Q3 group (-0.19-<0.49, n=8 803), Q4 group (≥0.49, n=8 803). The study subjects were followed up, with the endpoint defined as the occurrence of new-onset cardiovascular disease, defined as myocardial infarction and stroke. The follow-up period began after the physical examination in 2010 and ended at the date of the endpoint event or December 31, 2022, whichever came first. Cox proportional hazard regression model was used to analyze the impact of cumulative atherogenic index of plasma on the risk of new-onset cardiovascular disease and its subtypes, with trend tests conducted. Stratification was performed based on hypertension status, diabetes status, and low-density lipoprotein cholesterol (LDL-C) levels (<3.4 mmol/L or ≥3.4 mmol/L) to examine multiplicative interactions with the cumulative atherogenic index of plasma, and Cox proportional hazards regression analysis was subsequently conducted. Results: Among 35 212 participants, 26 636 (75.6%) were male, with an age of (45.4±8.3) years. Cardiovascular disease occurred in 2 075 cases (5.9%), of which 390 (1.1%) had myocardial infarction and 1 725 (4.9%) had stroke. During a follow-up of (11.5±2.0) years, the incidence densities of new-onset cardiovascular disease from Q1 to Q4 groups were 3.08, 4.70, 5.55 and 7.23 per 1 000 person-years, respectively. Cox proportional hazard regression model showed that, compared with the Q1 group, after adjusting for confounding factors, the HRs(95%CIs) of cardiovascular disease in Q2, Q3 and Q4 groups were 1.27 (1.10-1.48), 1.33 (1.14-1.56), 1.43 (1.19-1.72), respectively, the differences were statistically significant (all P<0.05). The risk of cardiovascular disease showed an increasing trend across the Q1 to Q4 groups (P_trend<0.001). In the endpoint-specific analyses for myocardial infarction and stroke, stroke demonstrated a similar trend (P_trend=0.002), while no statistically significant difference was observed for myocardial infarction (P_trend=0.465). Subgroup analysis showed that there were potential multiplicative interactions between different levels of LDL-C, the presence or absence of hypertension or diabetes, and the cumulative atherogenic index of plasma (all P for interaction<0.05). In a low-risk population with LDL-C<3.4 mmol/L, non-hypertensive, or non-diabetic, the cardiovascular disease risk in the Q4 group increased by 48%, 59%, and 49% compared to the Q1 group (all P<0.05), respectively. Conclusions: In the middle-aged and young populations, a high level of cumulative atherogenic index of plasma is associated with an increased risk of cardiovascular disease. This elevated risk is independent of the effects of traditional risk factors and remains significant even among low-risk populations.
