Impact Of Treating Maternal Periodontal Disease On The Risk Of Preterm Birth And Low Birth Weight: An Umbrella Review Of Systematic Reviews, May Salama, Abdullah Al-Taiar

College of Health Sciences Posters

Pregnancy involves complex physical and hormonal changes that significantly impact almost every organ system, including the oral cavity. The presence of oral disease in women has consequences for both their child and their health. The two main oral conditions linked to pregnancy are gingivitis and periodontal disease. Several studies have demonstrated that there is a positive association between periodontal disease and adverse pregnancy outcomes such as preterm birth (PTB) and low birth weight (LBW). PTB and LBW are among the leading causes of perinatal mortality and morbidity. It has been hypothesized that periodontal disease may cause PTB and/or LBW either …

Advanced Microstructural Characterization Of Functionally Graded Dental Ceramic Material For Materials-Informed Finishing, Angani Vigneswaran

Theses and Dissertations--Manufacturing Systems Engineering

Yttria-stabilized tetragonal zirconia polycrystal (Y-TZP) has gained popularity as the choice of material for dental prosthetics. Ivoclar Vivadent’s IPS e.max ZirCAD Prime dental ceramic incorporates a unique gradient technology that varies the yttria content over the thickness of the material. The top layer is composed of 5Y-TZP which is desired for its optical properties while the bottom layer is composed of a much stronger 3Y-TZP. In between the two layers, 5Y-TZP and 3Y-TZP are mixed to form a transition layer. Varying the amount of yttria allows for more esthetically pleasing translucency in the visible areas of the restoration without compromising …

The localized form of PP is characterized by a much more discreet inflammation and slow evolution. It can be associated with a known underlying systemic disease or may occur as part of a recognized syndrome or as an isolated finding. Different treatment modalities can be used …

Biological Parameters And The Histological Response In Rectal Cancer Treated By Neoadjuvant Chemoradiotherapy: A Moroccan Cohort, A. Naim, N. Bouanani, F. Safini, S. Mounaime, Soumaya Rafii, L. Lachker, F. Guessous, M. Khaliss, N. Tawfiq, A. Badou

Health Sciences

Introduction: Multimodal management of rectal cancer, combining neoadjuvant Radio chemotherapy followed by total Mesorectal therapy (TME), has been shown to improve locoregional control. However, the histological response is variable independently of the initial tumor stage. Some recent data suggest the usefulness of the lymphocyte-monocyte ratio (LMR), neutrophil-lymphocyte ratio (NLR), and platelet-lymphocyte ratio (PLR) in predicting the histological response to neoadjuvant therapy. This study aimed to investigate the correlation between the complete histological response (pCR) after neoadjuvant radio chemotherapy and biological parameters (LMR, NLR and PLR) in rectal cancer patients.

PATIENTS AND METHODS: This retrospective study was conducted in three Moroccan …

Cancer Immunotherapy: A Breakthrough In Patient Care, Abdou-Samad Kone, Nour El Imane Issam Salah, Amina Ghouzlani, Abdallah Badou

Health Sciences

Cancer is one of the world's leading causes of death. Conventional therapies, such as surgical resection, radiotherapy, and chemotherapy, have improved patient management and have shown overwhelming progress. However, the incidence and mortality rates among cancer patients are still extremely high, at approximately 20,5 % and 10,6 % for both sexes, respectively. This may be due to the heterogeneity of tumors, their special microenvironment, and the development of resistance to certain conventional therapies. The concept of immunotherapy provided a new perspective on patient treatment. The interaction of tumor cells with their microenvironment depends on different factors and conditions that promote …
