Impact of COVID-19 on youth's mental health in Egypt.

Background: Youth represent 21% of the Egyptian population; such proportion can create a leading demographic power for economic development and transition. However, with the current COVID-19 pandemic, everyone is exposed to more than usual stressors, adding a burden to their mental health and well-being.

Aim: This study aims to understand the pandemic's effect on youth's mental health in Egypt to strengthen the intervention areas needed to tackle such issues.

Teprotumumab-Related Hyperglycemia.

Context: Graves orbitopathy (GO) or thyroid eye disease is a potentially sight-threatening and disfiguring autoimmune disease. Teprotumumab is a monoclonal antibody against the insulin-like growth factor-I receptor that was recently approved for GO treatment. Hyperglycemia is a recognized adverse event of teprotumumab, occurring in 10% of patients in 2 recent randomized controlled trials.

New Onset or Deterioration of Thyroid Eye Disease After mRNA SARS-CoV-2 Vaccines: Report of 2 Cases and Literature Review.

Context: Occurrence of Graves' disease (GD) has been reported following SARS-CoV-2 vaccine administration, but little is known about thyroid eye disease (TED) after SARS-CoV-2 vaccination.

Objective: We describe 2 cases of TED activation following mRNA SARS-CoV-2 vaccination and review additional cases reported in the literature.

Methods: We report 2 cases of TED activation following SARS-CoV-2 vaccination: 1 case of TED worsening in a patient with GD, and 1 of de novo active TED progressing to dysthyroid optic neuropathy in a patient with a history of Hashimoto hypothyroidism.

Preparation, characterization, and analysis of multi-walled carbon nanotube-based nanofluid: an aggregate based interpretation.

Nanofluids are gaining attention as an attractive solution for the sustainable machining of difficult-to-cut materials. Despite the enormous recent work in the literature, there are still contradictions concerning the effect of different preparation factors on the characteristics of nanofluids and the underlying mechanisms governing them. In the present study, the effect of varying the preparation factors, namely, multi-walled carbon nanotube (MWCNT) concentration, sonication time, and surfactant amount on various nanofluid characteristics and the interactions among these characteristics were studied.

Ottawa Knee Rule: Investigating Use and Application in a Tertiary Teaching Hospital.

Background Knee injuries are encountered commonly in the emergency departments (EDs) in Ireland. Validated clinical decision rules such as Ottawa knee rule (OKR) can be used in acute knee injury settings to reduce the number of unnecessary radiography. Clinical judgment can be used to distinguish between suspected fractures and non-fractures in many cases; however, radiography is still routinely requested.

Spectrophotometric studies on the complexation equilibria of Ni and Pb with 2-carboxy-2-hydroxy-5'-sulfo-formazylbenzene. Simultaneous determination of trace amounts of Ni and Pb.

Spectrophotometric studies have been made to investigate the reaction of Nickel and Lead with 2-carboxy-2'-hydroxy-5'-sulfoformazyl-benzene (zincon) in 50%(v/v) ethanol-water at 25 degrees C and an ionic strength of 0.1 M NaClO4. A complete picture of the complexation equilibria in the pH range (4.
