Blockchain Based Auditable Access Control For Business Processes With Event Driven Policies.

The use of blockchain technology has been proposed to provide auditable access control for individual resources. Unlike the case where all resources are owned by a single organization, this work focuses on distributed applications such as business processes and distributed workflows. These applications are often composed of multiple resources/services that are subject to the security and access control policies of different organizational domains.

Orchestration and Management of Adaptive IoT-centric Distributed Applications.

Current Internet of Things (IoT) devices provide a diverse range of functionalities, ranging from measurement and dissemination of sensory data observation, to computation services for real-time data stream processing. In extreme situations such as emergencies, a significant benefit of IoT devices is that they can help gain a more complete situational understanding of the environment. However, this requires the ability to utilize IoT resources while taking into account location, battery life, and other constraints of the underlying edge and IoT devices.

Anesthetic Management of Emergency Insulinoma Resection: Case Report and Review of Literature.

Insulinoma, a neuroendocrine tumor originating from pancreatic islets, presents unique challenges in diagnosis and management. We present a case of a 73-year-old female with recurrent hypoglycemia leading to syncope, who underwent emergency pancreatectomy for a secreting insulinoma with multiple comorbidities. This case report aims to shed light on the complexities of insulinoma management and the importance of tailored perioperative strategies.

Tonsillar Trauma During Video Laryngoscopy: A Case Report.

Potentially difficult airways warrant the use of airway adjuncts, which, if not used with caution, can cause trauma to the oral cavity. Although most operators are familiar with modern airway adjuncts, as they are not routinely used, adverse events can occur. Since its introduction, a video laryngoscope (VL) has been lauded as a necessary instrument for airway management in and out of the operating room.

Impact Of Incentive-Based Game Therapy And Transporting Children On Toy Vehicle To Operation Theatre On Reducing Anxiety Prior To Induction Of Anesthesia.

Objective: To see if transporting paediatric patents to operation theatres using a battery operated vehicle decreases preoperative anxiety and reduce incidents of postoperative adverse events.

Methods: The study was conducted from May to August 2019 at the Shaukat Khanum Memorial Cancer Hospital and Research Centre, Lahore, Pakistan, and comprised paediatric patients aged 3-5 years assessed as American Society of Anaesthesiologists grade I and II who were scheduled to undergo elective intrathecal chemotherapy under general anaesthesia. The subjects were randomised into intervention group A and control group B.

An Integrated Framework for Fault Resolution in Business Processes.

Cloud and edge-computing based platforms have enabled rapid development of distributed business process (BP) applications in a plug and play manner. However, these platforms do not provide the needed capabilities for identifying or repairing faults in BPs. Faults in BP may occur due to errors made by BP designers because of their lack of understanding of the underlying component services, misconfiguration of these services, or incorrect/incomplete BP workflow specifications.

Emergency Management of Ventilation Failure Through Blocked Tracheostomy Tube in a Paediatric Patient.

The most common complication of tracheostomy tubes in children is blockage of the tube. We report a case where ventilation after induction of anaesthesia was not possible even though there were no signs of impending obstruction. An eight-year-old child, recently diagnosed with left tonsillar embryonal rhabdomyosarcoma, presented for an MRI face and bone marrow biopsy before starting treatment.

A Framework for Dynamic Composition and Management of Emergency Response Processes.

An emergency response process outlines the workflow of different activities that need to be performed in response to an emergency. Effective emergency response requires communication and coordination with the operational systems belonging to different collaborating organizations. Therefore, it is necessary to establish information sharing and system-level interoperability among the diverse operational systems.

A Service-oriented Framework for Developing Personalized Patient Care Plans for COVID-19.

The COVID-19 pandemic has identified weaknesses and stresses in the existing healthcare and governance system, even in the most developed countries. Given the scale and scope of the pandemic, existing healthcare systems are heavily resource constrained, and home-based isolation has been considered as a potential first step for reducing both the disease spread and the stress on the healthcare system. However, the needs and requirements of home-based isolation are extremely unique for each patient, depending on their medical condition and comorbidities, family responsibilities, and environmental constraints.

SARS-CoV-2 UK, South African and Brazilian Variants in Karachi- Pakistan.

The COVID-19 pandemic has been evolving in Pakistan with the emergence of the United Kingdom, South African, and Brazilian variants. These variants of concern (VOC) are known for increased transmissibility and can also be responsible for avoiding immune responses. The gold standard to detect VOC is sequencing, however routine genomic surveillance in resource-limited countries like Pakistan is not always readily available.

Clinical Practice for Venous Thromboembolism Prophylaxis in Patients Undergoing Oncological Surgeries.

Objective To determine the proportion of patients receiving venous thromboembolism (VTE) prophylaxis after oncological surgeries as per the hospital standards and its comparison with the international guidelines. Methodology In the month of September 2019, all patients after elective oncological surgeries were reviewed for VTE prophylaxis administration and education. Results were shared with the department of surgery and Hospital Quality and Patient Safety Department.

Blockchain Based Auditable Access Control for Distributed Business Processes.

The use of blockchain technology has been proposed to provide auditable access control for individual resources. However, when all resources are owned by a single organization, such expensive solutions may not be needed. In this work we focus on distributed applications such as business processes and distributed workflows.

Circulating miR-21 as a prognostic and predictive biomarker in oral squamous cell carcinoma.

Background & Objective: The high-throughput analysis of circulating microRNAs (miRNAs) is an active area of biomarker research. The oral cancer remains a common cancer among Pakistani males that continues to present at an advance stage, thus exhibiting poor survival. MiRNA 21 (miR-21) is the most consistently over-expressed miRNA in different types of tumor tissues.

Vesicoureteral Reflux Detected on Post-void Image of (99m)Tc MAG3 Renal Scintigraphy.

(99m)Tc MAG3 scintigraphic scan is sensitive at depicting focal parenchymal abnormalities and can be used for the measurement of overall renal function. We experienced a 5-year-old boy presenting with bilateral flank fain, intermittent urinary stream and dysuria. On the post-void delayed image of (99m)Tc MAG3 scintigraphic scan vesicoureteral reflux was detected in left non-functioning kidney, which was missed on voiding cystourethrography.

Prediction of clinical outcome in treated neuroendocrine tumours of carcinoid type using functional volumes on 111In-pentetreotide SPECT imaging.

The quantification of the tumour volume is essential for the assessment of therapy-induced changes. Traditional methods of assessing the response of neuroendocrine tumours using radiological methods yield poor results, particularly within the liver. The aim of this study was to establish whether it would be possible to identify a method using functional volumes to predict the response of tumours to various therapies.
