Exploring Knowledge, Safety Practices, and Anxiety Level among Women of Reproductive Age During COVID-19 Outbreak: A Cross-Sectional Study.

Background: The global outbreak of coronavirus disease 2019 (COVID-19) and its consequences compromise the health of Women of Reproductive Age (WRA). The aim of this study was to assess the level of knowledge, safety practices, and anxiety levels among WRA during COVID-19 outbreaks.

Materials And Methods: A cross-sectional, correlational design was used to recruit a convenience sample of 453 WRA in Saudi Arabia.

Effectiveness of a low-intensity static magnetic field in accelerating upper canine retraction: a randomized controlled clinical trial.

Introduction: Neodymium-iron-boron magnets have been suggested as a contemporary method for accelerating the process of orthodontic tooth movement (OTM). A limited number of clinical trials evaluated their effectiveness in accelerating OTM which is desirable for both orthodontists and patients. The present study aimed to investigate the effectiveness of a low-intensity static magnetic field (SMF) in accelerating upper canine retraction movement.

Optimized Cylindrical Diffuser Powers for Interstitial PDT Breast Cancer Treatment Planning: A Simulation Study.

Purpose: It is well known that interstitial photodynamic therapy (iPDT) of large tumors requires effective planning to ensure efficient delivery of therapeutic dose to the target tumors. This should be achieved in parallel with minimal damage to the nearby intact tissues. To that end, clinical iPDT can be attained using cylindrical diffusing optical fibers (CDFs) as light sources.

A multi-bundle concentric coil wirelessly transferring power to in vivo implantable devices.

Biomedical devices implanted inside the human body have a heavy demand on battery power. The internal batteries are charged wirelessly through two coils. The primary is placed outside the chest and is fed with an electromagnetic field, while the implanted secondary delivers current to the batteries.

Statistical approach for brain cancer classification using a region growing threshold.

In brain cancer, a biopsy as an invasive procedure is needed in order to differentiate between malignant and benign brain tumor. However, in some cases, it is difficult or harmful to perform such a procedure, to the brain. The aim of this study is to investigate a new method in maximizing the probability of brain cancer type detection without actual biopsy procedure.

Utilizing wavelet transform and support vector machine for detection of the paradoxical splitting in the second heart sound.

Paradoxical splitting occurs when pulmonic valve (P2) closes before the aortic valve (A2). This causes second heart sound (S2) to be a single sound during inspiration and split during exhalation. Etiology delay in aortic closure: aortic stenosis, volume overload of left ventricle (LV), conduction defects in LV, and left bundle branch block (LBBB).

Experimental assessment of electrical impedance imaging for hyperthermia monitoring.

Two experimental studies are presented that attempt to assess the use of electrical impedance tomography (EIT) to map thermal changes deep in the body. The first was a joint study between our group in Sheffield and the Daniel den Hoed Cancer Center in Rotterdam, funded by the COMAC-BME Hyperthermia project. Phantom and in vivo experiments were conducted with a deep heating ring-capacitive hyperthermia device; the results highlighted some of the inherent problems (electromagnetic interference, nonuniform sensitivity) that remain to be solved for this application.

Electrical impedance tomography: prospects for non-invasive control of deep hyperthermia treatments.

Electrical Impedance Tomography (EIT) is assessed as a means of monitoring deep hyperthermia treatments in both phantom and in vivo studies. EIT measurements during heating of an inhomogeneous leg phantom show good correlation with internal temperatures measured with invasive probes. Measurements whilst altering the temperature of the stomach contents in volunteers demonstrate the capability of EIT for imaging temperature change at depth in the torso.

Quantitative assessment of impedance tomography for temperature measurements in microwave hyperthermia.

The objective of this study is a non-invasive assessment of the thermal dose in microwave hyperthermia. We intend to monitor the induced temperature rise via the change in the resistivity of body tissue, and hence control the microwave power during treatment. An initial feasibility study using electrical impedance tomography in vivo has indicated that a microwave induced temperature difference of a suitable magnitude can be mapped from a knowledge of the temperature coefficient of conductivity for tissue (typically 2% per degrees C).
