Modified Vogel's approximation method for the unbalanced transportation problem

AbstractShimshak et al. [2] and Goyal [3] describe modifications to Vogel's Approximation Method for obtaining initial solutions to the unbalanced transportation problem. In this paper, we propose a further modification that could result in better initial solutions

Conservative management in case of placenta accreta followed by hysterectomy

With a rise in number of caesarean sections we are also seeing an increase in the adherent placenta that form a part of placenta accreta spectrum. Early identification and appropriate management and monitoring is very important in these patients as they can have hemorrhage that can cause significant maternal and fetal morbidity and mortality. This is a case of conservative management of a woman with placenta accreta spectrum, use of uterine artery balloon ligation to decrease the intra-operative blood loss, leaving placenta in situ, methotrexate therapy and follow up of the patient that ultimately led to hysterectomy. It highlights the importance of managing these women in adequately equipped center with the required expertise and intensive care support and multidisciplinary management to improve patient care leading to good maternal and fetal outcome.

Designing pedagogically-driven approaches to technology-enhanced learning for community health workers

Technology-enhanced learning (TEL) is well established as a teaching modality. However, there is a lack of evidence for the pedagogical approaches used to design TEL for community health workers (CHWs). This chapter highlights the importance of contextualizing CHW learning within the wider health system. Theoretical approaches to consider when designing a TEL-based education and training programme for CHWs are presented, with practical examples of how these approaches might be most appropriately embedded in the delivery of CHW training. Finally, a framework for the design of pedagogically-grounded TEL-based learning for CHWs is presented, which may be used to help guide the design of TEL-based educational interventions for CHWs
