Background: In Kenya, the Maternal Mortality Ratio (MMR) is approximated to 362 maternal deaths per 100,000 live births while the stillbirth rate stands at 23 deaths per 100 live births which are far below the target of 147 maternal mortality per 100,000 live births and 12 stillbirths per 100 live births respectively. Progress in addressing preventable maternal and newborn deaths and stillbirths depend on the improvement of the quality of maternal, fetal and newborn care throughout the continuum of care. Objective: To determine the effect of mentorship and training in improving the provision of Basic Emergency Obstetric Newborn Care (BEmONC) and Comprehensive Emergency Obstetric Newborn Care (CeMONC) services among health workers in Samburu County. Methodology: A one-week training intervention was carried among health workers in level three, four and five health facilities by master trainers. Using two tools adopted from MEASURE Evaluation and a structured questionnaire, a total of 54 (before the intervention) and 64 (after the intervention) health workers from 29 health facilities were interviewed. Training effectiveness was assessed by means of questionnaires administered pre- and post-training, by correlating post-training results of health workers, and through participatory observations at the time of on-site supervisory visits, mentorship and monthly meetings. An assessment was conducted to measure the level of confidence of the health workers in performing their duties. Results: Central Samburu had the majority of the health workers both at the pre-intervention (44.4%) and post-intervention (51.6%), North Samburu had an extra health worker at post-test while no change in numbers was recorded in East Samburu. A majority of the health workers across the three sub-counties were 31 - 40 years old, with only 2 (3.8%) aged 51 years and above. Following the interventions, improvements in the practice of BEmONC servic

In a recent article published in Science,Sharma et *** the essential role of saposins in cross-presentation of tumor membraneassociated antigens by dendritic cells(DC)to CD8^(+)T cells.1 However,antigen cross-presentation,which is fundamental in cancer cell elimination,is hindered in tumor DC by hyperglycosylation of the common saposin precursor prosaposin(pSAP)leading to impaired T cell tumor immunity-yet,the potential of recombinant pSAP to re-establish T cell responses may offer a novel way to counteract immune evasion in a therapeutic approach.

Towards a lightweight security framework using blockchain and machine learning

BLOCKCHAIN-RESEARCH AND APPLICATIONS 2024年第1期5卷 107-118页

Cyber-attacks pose a significant challenge to the security of Internet of Things (IoT) sensor networks, necessitating the development of robust countermeasures tailored to their unique characteristics and limitations. Various prevention and detection techniques have been proposed to mitigate these attacks. In this paper, we propose an integrated security framework using blockchain and Machine Learning (ML) to protect IoT sensor networks. The framework consists of two modules: a blockchain prevention module and an ML detection module. The blockchain prevention module has two lightweight mechanisms: identity management and trust management. Identity management employs a lightweight Smart Contract (SC) to manage node registration and authentication, ensuring that unauthorized entities are prohibited from engaging in any tasks, while trust management uses a lightweight SC that is responsible for maintaining trust and credibility between sensor nodes throughout the network's lifetime and tracking historical node behaviors. Consensus and transaction validation are achieved through a Verifiable Byzantine Fault Tolerance (VBFT) mechanism to ensure network reliability and integrity. The ML detection module utilizes the Light Gradient Boosting Machine (LightGBM) algorithm to classify malicious nodes and notify the blockchain network if it must make decisions to mitigate their impacts. We investigate the performance of several off -the -shelf ML algorithms, including Logistic Regression, Complement Naive Bayes, Nearest Centroid, and Stacking, using the WSN-DS dataset. LightGBM is selected following a detailed comparative analysis conducted using accuracy, precision, recall, F1 -score, processing time, training time, prediction time, computational complexity, and Matthews Correlation Coefficient (MCC) evaluation metrics.
