Sudden Maternal Death from Suspected Amniotic Fluid Embolism and a Dead Baby Delivered with Natal Teeth

Amniotic fluid embolism (AFE) is a rare presentation in obstetric emergencies that carries great risk for the life of both mother and fetus. It is usually characterized by sudden cardiovascular collapse, respiratory distress and disseminated intravascular coagulation. Here we present a case of sudden death of a pregnant woman due to suspected AFE. We also present a rare finding of natal teeth in her deceased baby, which along with reported AFE in the mother, is an unlikely event in the medical literature

Assessing feedback practices in classroom assessment at federal government educational institutions of Lahore, Pakistan

This study aimed at investigating current feedback practices in classroom assessment. A sample of 300 participants including 150 teachers and 150 students each was selected using a stratified random sampling technique. Under the positivist paradigm, a survey method was deployed to conduct the research. In this study, a self-developed questionnaire comprising 20 items was used for data collection from the participants. The collected data was analyzed using SPSS (24.0). Frequencies and percentages were calculated in descriptive stats, whereas an independent sample t-test was used to verify research hypotheses. The study explored that class tests, class exercises, homework, and trial work during lessons were the most commonly used assessment tools whereas essay-type questions, and multiple-type questions were the most commonly used assessment formats. Moreover, it was found that delayed marking and returning of assessment tasks, less or no motivation for better performance, and lack of contact with parents were the major issues in feedback on classroom assessment at Federal Government Educational Institutions (FGEIs). The study recommended that the workload of teachers should be reduced so that they may have sufficient time to design and evaluate assessment tasks. Professional training on assessment on regular basis may be arranged for the faculty. A comprehensive plan of classroom assessment may be proposed by school principals along with a defined syllabus and be timely communicated the same to all stakeholders. An effective mechanism of monitoring to assess classroom assessment feedback practices may also be established

Laparoscopic-assisted percutaneous endoscopic gastrostomy tube insertion in the immediate post-partum period for head and neck cancer

Abstract Percutaneous endoscopic gastrostomy (PEG) tube placement serves as a well-tolerated and efficacious technique for long-term enteral access in patients with medical conditions precluding oral food intake. The nutritional optimisation of patients with oral cancer is mostly achieved via PEG tube placement. However, certain special situations, such as pregnancy and the immediatepost-partum period, may render the placement of PEG tubes to be a challenge. A 28-year-old pregnant female patient presented to us with the diagnosis of squamous cell carcinoma of the tongue during her third trimester. Definitive surgical resection was planned post-delivery along with simultaneous PEG tube placement. Immediately following delivery via an elective Caesarean section, she successfully underwent laparoscopic-assisted PEG tube placement. A gravid uterus or an immediately post-partum distended uterus poses significant difficulties whilst attempting PEG insertion. However, laparoscopic-assisted PEG insertion in a controlled setting may make the process safer to perform

Disaster management using D2D communication with power transfer and clustering techniques

Device-to-device (D2D) communications as an underlay to cellular networks can not only increase the system capacity and energy efficiency but also enable national security and public safety services. A key requirement for these services is to provide alternative access to cellular networks when they are partially or fully damaged due to a natural disaster event. In this paper, we employ energy harvesting (EH) at the relay with simultaneous wireless information and power transfer to prolong the lifetime of energy constrained network. In particular, we consider a user equipment relay that harvests energy from radio frequency signal via base station and use harvested energy for D2D communications. We integrate clustering technique with D2D communications into cellular networks such that communication services can be maintained when the cellular infrastructure becomes partially dysfunctional. Simulation results show that our proposed EH-based D2D clustering model performs efficiently in terms of coverage, energy efficiency, and cluster formation to extend the communication area. Moreover, a novel concept of power transfer in D2D clustering with user equipment relay and cluster head is proposed to provide a new framework to handle critical and emergency situations. The proposed approach is shown to provide significant energy saving for both mobile users and clustering heads to survive in emergency and disaster situations

Investigation of Alumina-Doped Prunus domestica Gum Grafted Polyaniline Epoxy Resin for Corrosion Protection Coatings for Mild Steel and Stainless Steel

Eco-friendly inhibitors have attracted considerable interest due to the increasing environmental issues caused by the extensive use of hazardous corrosion inhibitors. In this paper, environmentally friendly PDG-g-PANI/Al$_2$O$_3$ composites were prepared by a low-cost inverse emulsion polymerization for corrosion inhibition of mild steel (MS) and stainless steel (SS). The PDG-g-PANI/Al$_2$O$_3$ composites were characterized by different techniques such as X-ray diffraction (XRD), UV/Vis, and FTIR spectroscopy. XRD measurements show that the PDG-g-PANI/Al$_2$O$_3$ composite is mostly amorphous and scanning electron micrographs (SEM) reveal a uniform distribution of Al$_2$O$_3$ on the surface of the PDG-g-PANI matrix. The composite was applied as a corrosion inhibitor on mild steel (MS) and stainless steel (SS), and its efficiency was investigated by potentiodynamic polarization measurement in a 3.5% NaCl and 1 M H$_2$SO$_4$ solution. Corrosion kinetic parameters obtained from Tafel evaluation show that the PDG-g-PANI/Al$_2$O$_3$ composites protect the surface of MS and SS with inhibition efficiencies of 92.3% and 51.9% in 3.5% NaCl solution, which is notably higher than those obtained with untreated epoxy resin (89.3% and 99.5%). In particular, the mixture of epoxy/PDG-g-PANI/Al$_2$O$_3$ shows the best performance with an inhibition efficiency up to 99.9% on MS and SS. An equivalent good inhibition efficiency was obtained for the composite for 1M H$_2$SO$_4$. Analysis of activation energy, formation enthalpy, and entropy values suggest that the epoxy/PDG-g-PANI/Al$_2$O$_3$ coating is thermodynamically favorable for corrosion protection of MS and exhibits long-lasting stability

Exploring organizational management of extrovert school leadership

The study aimed at determining the personality traits of extroversion and introversion of school leadership and evaluating their organizational management in Federal Government Educational Institutions (FGEIs). A quantitative research design along with a positivist paradigm was followed. The total population consisted of 68 school principals and 592 teachers of FGEIs in the Gujranwala, Fazaia, and Lahore Regions from which 54 principals and 381 teachers were selected using a random sampling technique. Eysenck Personality Inventory (EPI) was deployed to collect information about personality traits and data regarding organizational management, the researchers used a self-developed questionnaire. Pearson correlation r and t-tests were deployed for inferential stats. The results showed that extrovert school leaders perform their duties well as they hold a clear concept of the vision and mission of the organization, set up an accepted procedure to plan short-term and long-term goals, share responsibilities with all stakeholders following their skills, and ensure the smooth functioning of the school with the help of all stakeholders. In comparison, introverted school principals show less interest in the organizational management of their schools. Moreover, organizational management of school leadership has a positive correlation with the personality trait of extroversion and a significant difference can be seen in organizational management of an extrovert and an introvert school principal. It was recommended that the performance indicators and standards of school principals should be effectively communicated to school leadership. Introvert school leadership should be provided with the necessary psychological training to reduce this shortcoming of personality
