Papillary Thyroid Carcinoma and Pregnancy: What Impact on Prognosis?

Introduction: The impact of pregnancy on the prognosis of papillary thyroid carcinoma (PTC) has been debated for several decades;however, no definitive conclusions have been reached. The main objective of this study is to demonstrate the short-term influence of pregnancy on the evolution and prognosis of PTC. Materials and Methods: A prospective descriptive and analytical study was conducted in the Endocrinology and Diabetology Department at the Hassan II University Hospital in Fez, including patients followed for papillary thyroid carcinoma presenting with a pregnancy during the year 2019 and 2020. The follow-up of these patients was continued until 1 year postpartum. We studied the clinical, paraclinical and therapeutic factors that could influence the prognosis of the disease. Results: We included 26 patients. Our study showed a significant correlation between recurrence and the presence of unfavorable histological signs (p = 0.02) as well as the initial Tg level (0.01). However, pregnancy was not an influencing factor (p = 0.41). Conclusion: Pregnancy does not seem to be a factor aggravating the prognosis of differentiated thyroid cancers.

Numerical Study of Temperature and Electric Field Effects on the Total Optical Absorption Coefficient in the Presence of Optical Inter-Conduction-Subband Transitions in InGaN/GaN Single Parabolic Quantum Wells

In this paper,we theoretically investigate the total optical coefficient(TOAC)considering 1S-2P and 2S-2P conduction subband transitions in a single parabolic quantum well(SPQW)with an on-center hydrogen-like impurity.Within the framework of the effective-mass approximation,the Schrödinger equation is solved numerically to obtain the eigenvalues and their corresponding eigenvectors using the finite difference method.The calculations are performed for finite confinement potential height,taking into account the dielectric and effective mass mismatches between GaN and InGaN materials under the considered electric field and temperature effects.The temperature dependence of the effective mass,dielectric constant and band gap energy are obtained accordingly.On the one hand,the results show that a significant shift is produced with the variation of both the temperature and the intensity of the electric field.On the other hand,the absorption spectrum is shifted to lower energies with increasing both electric field strength and temperature.Moreover,its amplitude is enhanced with an increase in the intensity of the electric field,and show a slight drop with increasing temperature for the two optical transitions considered.The results show that such parameters can be used to adjust the optical properties of single parabolic Quantum Well for solar cell applications.

Embodied Faith and the Limits of Female Agency in Randa Abdel-Fattah's Does My Head Look Big in This?

The present essay discusses Randa Abdel-Fattah's Does My Head Look Big in This?by focusing on the rendition of Islam as an axis of social agency in an environment that is excessively antagonistic of any version of Islam that falls outside the contours of the "liberal model"morphed by the Western creed of equality,liberty.Amal,the protagonist,embodies the dilemmas of choice and agency within an ideological rubric which disassociates such notions from faith-based convictions.The analysis relies on the notion of Muslim agency as theorized by Saba Mahmood,for whom the conscious formation of deeply rooted religious subjectivities is sidelined within the modern secular rubrics of self-formation.The article also draws on W.E.B Du Bois's concept of double consciousness to highlight the extent to which Muslim female bodies are caught at the intersection between religion and nation.Hence,this essay discloses the challenges facing Muslim women whose exercise of agency is tied to their religious beliefs in a backdrop characterized by multicultural and secular economies.More particularly,it explores Amal's religious tradition of habituated practices-such as wearing the veil in a hostile environment--as embodiments of autonomous agency.
