Lipid-based nutrient supplement to address child undernutrition and enteric parasitic infections in India
No full textUndernutrition is an outcome of insufficient food intake and repeated infectious diseases. Lipid-based nutrient supplements (LNS) are calorie and nutrient dense food products that are suitable to complement most food rations due to their long shelf life and convenience. Although available in other markets, staple-based LNS for India do not exist. More importantly, no currently available LNS formulations address the other immediate causes of undernutrition such as parasitic infections and gut inflammation in children. The objective of this study was to develop advanced LNS 2.0 with improved shelf stability, consumer acceptability, and antiparasitic activity via added oregano essential oil (OEO) bioactives.
LNS were formulated using Indian staple dairy ingredients, and optimized using Response Surface Methodology (RSM) via face centered composite design with four factors and three coded levels: antioxidant (ascorbyl palmitate; at 0.0, 0.01, 0.03%), emulsifier (soy lecithin; at 0.5, 1.0, 1.5%), omega-3 (flaxseed oil (FO); at 0, 5, 10%) and accelerated storage temperature and time (23 and 40±2°C; at 0, 3, 6 months). Consumer acceptability was assessed using a 9-point hedonic scale among Indian mothers and students. Next, a dual modality in vitro cell culture model was employed to investigate the effect of OEO and its main bioactive carvacrol on prevention of parasite C. parvum invasion and infection of HCT-8 cells. Finally, β-Cyclodextrin (β-CyD) encapsulation of OEO and carvacrol (1:1 molar) was utilized to mask the potent flavor of bioactives, and achieve controlled intestinal delivery of bioactives, measured using triangle sensory test and 2-phase in-vitro digestion model, respectively.
Optimal levels to maximize storage time and flaxseed oil and minimize oxidation were found as 0.02% antioxidant 1.5% emulsifier, and 4.9% FO. LNS formulations were found acceptable with or without FO similar to other commercial supplements. OEO and carvacrol were found to reduce relative C. parvum infectivity in a dose-dependent manner to 55.6 ± 10.4% and 45.8 ± 4.1% at 60 and 30 μg/mL of OEO and CV, respectively. Lastly, β-CyD complexes of OEO and CV were found significantly stable (p<0.05) through the gastric and intestinal phase enabling their potential release in colon via fermentation by colonic microflora. Triangle tests revealed no significant difference in color, smell, and taste between LNS with and without β-CyD-OEO complexes. In conclusion, staple-based LNS functionalized with β-CyD-OEO complex were feasible and can potentiate their application in addressing undernutrition and parasitic infections in at-risk populations.Submission published under a 24 month embargo labeled 'Closed Access', the embargo will last until 2019-08-01The student, Shashank Gaur, accepted the attached license on 2017-06-14 at 18:43.The student, Shashank Gaur, submitted this Dissertation for approval on 2017-06-14 at 18:58.This Dissertation was approved for publication on 2017-06-20 at 13:20.DSpace SAF Submission Ingestion Package generated from Vireo submission #11224 on 2017-09-29 at 11:13:44Made available in DSpace on 2017-09-29T16:39:10Z (GMT).

Can Distributional Semantic Models identify substitutes and complements in shopping cart data?
No full textSubstitutive and Complementary relationships are natural attributes behind products and crucial to identify in order to understand a product’s functional value, in turn consumer needs. Recent research claimed that distributional semantic models can effectively identify and retrieve substitutes and complements for any product in the shopping cart data, but falls short in providing any empirical evaluation. The aim of this dissertation was to test the validity of this hypothesis. Different types of DSMs were implemented and evaluated on shopping cart data for identifying substitutes. The results revealed unexpectedly poor performance of all the DSMs in retrieving appropriate substitutes and provided strong evidence of model’s incapability to capture these relations. Subjected to further evaluation, this study indicated a need for more intricate models to identify complex relationships of substitutes and complements

This systematic review synthesizes clinical evidence on its safety, efficacy, and pharmacological properties in managing arterial and venous thrombotic events.
Methods: Following PRISMA guidelines, we searched PubMed, Embase, Scopus, Cochrane Library, ClinicalTrials.gov, and Web of Science for clinical trials and observational studies on asundexian until January 2025. Inclusion criteria included studies reporting safety, efficacy, and pharmacokinetics/pharmacodynamics (PK/PD) outcomes. Two reviewers independently screened studies and extracted data, with quality assessed using the Cochrane Risk of Bias 2 tool.
Results: Eleven trials (n > 21,000, phases 1-3) were included. Asundexian suppressed FXIa activity, with phase 2 trials (e.g., PACIFIC-AF, PACIFIC-STROKE) showing reduced bleeding compared to apixaban. However, the phase 3 OCEANIC-AF trial was terminated early due to inferior efficacy in atrial fibrillation, with higher stroke/systemic embolism rates (2.5%) versus apixaban. PK/PD data support once-daily dosing with minimal drug interactions. Safety concerns include potential abnormal uterine bleeding, with limited data.
Conclusion: Asundexian shows promise in reducing bleeding but lacks efficacy in high-risk settings like atrial fibrillation. Ongoing trials are needed to define its role in specific thrombotic conditions

Despite an alarming rise in gastrointestinal (GI) conditions - including peptic ulcers, GI cancers, and infectious colitis - postgraduate training in gastroenterology remains underdeveloped. This narrative review examines the structural, educational, and systemic challenges facing GI training across the continent, drawing from peer-reviewed literature, institutional surveys, and global health databases. Findings reveal substantial heterogeneity in training program length, curriculum standards, and procedural exposure. Advanced techniques like endoscopic retrograde cholangiopancreatograph and endoscopic ultrasound remain inaccessible to most trainees, while simulation facilities and didactic teaching are often limited. Faculty shortages, lack of protected research time, and minimal access to conferences further compromise academic development and contribute to workforce attrition. Despite these challenges, several innovative approaches offer hope. Low-cost simulation models, tele-education, and hybrid conference formats are improving access to training. Regional centers of excellence and North-South collaborations - such as partnerships between African institutions and the British Society of Gastroenterology (BSG) - have demonstrated success in building local capacity. The expansion of digital platforms, diaspora engagement, and public-private partnerships presents further opportunities. Recommendations include implementing competency-based assessments, supporting faculty development, creating regional accreditation bodies, and investing in infrastructure. Addressing systemic inequities in conference access and leveraging geospatial surveillance tools could also enhance disease mapping and policy planning. Ultimately, strengthening gastroenterology education in Africa requires coordinated regional and international action to develop sustainable, context-sensitive training ecosystems. This review provides a roadmap for achieving equitable specialist training and improving digestive health outcomes across the continent

While traditionally associated with fever and systemic complications, the neurological impact of malaria, including stroke, has become a significant concern. This review aims to examine the incidence, clinical presentation, and outcomes of stroke in individuals with malaria, highlighting the role of malaria in both ischaemic and haemorrhagic strokes. A literature search identified nine studies published between 1999 and 2024, comprising case reports and case series involving malaria-related strokes in patients aged 2 to 47 years. Most cases involved Plasmodium falciparum, with a notable association between this parasite and haemorrhagic strokes. Plasmodium vivax, while less commonly implicated, was associated with ischaemic strokes, especially in younger patients. Diagnostic challenges, including misdiagnosis, were frequently encountered due to the overlap of neurological symptoms with cerebral malaria, emphasizing the need for a high index of suspicion. The pathophysiology of malaria-related strokes is multifactorial, with both mechanical obstruction of cerebral vessels and hypercoagulable states contributing to stroke development. Treatment generally involves a combination of anti-malarial therapy and supportive care, including management of complications such as raised intracranial pressure or seizures. Outcomes vary, with ischaemic stroke patients showing better recovery than those with haemorrhagic strokes. However, mortality remains high, particularly in cases with severe complications like cerebral venous thrombosis. Early diagnosis and intervention are crucial for improving survival and minimizing long-term neurological impairment. Further research is needed to refine diagnostic approaches, elucidate the underlying mechanisms, and optimize management strategies for stroke in patients with malaria
SPARK: Secure Pseudorandom Key-based Encryption for Deduplicated Storage
No full textDeduplication is a widely used technology to reduce the storage and communication cost for cloud storage services. For any cloud infrastructure, data confidentiality is one of the primary concerns. Data confidentiality can be achieved via user-side encryption. However, conventional encryption mechanism is at odds with deduplication. Developing a user-side encryption mechanism with deduplication is a vital research topic. Existing state-of-the-art solutions in security of deduplication are vulnerable to dictionary attacks and tag inconsistency anomaly. In this paper, we present SPARK, a novel approach for secure pseudorandom key-based encryption for deduplicated storage. SPARK achieves semantic security along with deduplication. Security analysis proves that SPARK is secure against dictionary attacks and tag inconsistency anomaly. As a proof of concept, we implement SPARK in realistic environment and demonstrate its efficiency and effectiveness

Heart rate variability, the physiological variation in time intervals between successive heartbeats, is a valuable marker used to index the functionality of the cardiac Autonomic Nervous System in healthy individuals and patients with cardiovascular and non-cardiovascular disorders. In cardiac surgery, heart rate variability can be a crucial tool for the operative management of patients. This manuscript reviews the role of heart rate variability in surgery, its current applications, and emerging trends in clinical settings.
Main body
Clinically, heart rate variability is used to evaluate surgical risk by identifying patients with impaired autonomic function who may be predisposed to complications such as arrhythmias or hemodynamic instability. During surgery, heart rate variability monitoring provides real-time insights into autonomic responses to anesthesia, fluid management, and surgical stress. Postoperatively, heart rate variability is instrumental in detecting early signs of sepsis, myocardial dysfunction, and autonomic dysregulation, thereby guiding timely interventions. Despite its clinical potential, heart rate variability analysis faces challenges, including variability in measurement techniques, limited standardization of interpretation, and the influence of confounding factors such as medications and mechanical ventilation. Additionally, real-time integration into surgical workflows remains underdeveloped.
Conclusions
Emerging trends in heart rate variability in cardiac surgery include the use of artificial intelligence for automated heart rate variability analysis, wearable biosensors for continuous monitoring, and tailored therapeutics. There are also new advances in machine-learning algorithms for heart rate variability interpretation, which are promising for enhancing ischemia detection and refining real-time decision-making during high-risk cardiac procedures. Thus, future research should focus on refining heart rate variability–based predictive models and integrating heart rate variability metrics into multimodal perioperative management strategies to improve surgical outcomes
