Bone Dimensional Stability With Versus Without A Stent Following Apically Repositioned Flap And Single-Stage Implant Placement: A Randomized Clinical Trial, Dalia Ghalwash, Ahmed Hamdy, Jazia Alblowi

Dentistry

Abstract Maintaining peri-implant bone and tissue health is essential for long-term implant success. The effectiveness of adjunctive stent stabilization is still unclear, though the apically repositioned flap (ARF) improves soft tissue conditions. Therefore, this study assessed whether the use of stents during single-stage placement improves peri-implant bone changes and clinical outcomes following ARF. This randomized clinical trial included twenty partially edentulous patients who were divided into two groups: ARF with stent stabilization (n = 10) and ARF using conventional suturing (n = 10). At baseline, three months, and six months, radiographic bone dimensions measured by cone-beam computed tomography (CBCT) were …

Department of Obstetrics & Gynecology Faculty Publications

[Introduction] Glucagon-like peptide-1 (GLP-1)-based therapies are increasingly prescribed for the treatment of type 2 diabetes and obesity, with rapid uptake of newer agents such as semaglutide and tirzepatide [1, 2]. These medications improve glycemic control and promote weight loss and are now widely used among reproductive-aged individuals [2, 3]. However, GLP-1-based therapies are typically discontinued prior to pregnancy because of limited safety data and potential fetal risks, and current guidance recommends avoiding use during pregnancy [3]. As prescribing expands, a growing number of individuals entering pregnancy may have recent exposure to GLP-1-based …

Low-Lying Placenta Is Associated With Increased Risk Of Hemorrhage And Severe Maternal Morbidity: A Nationwide Analysis, May Abiad, Giulia Bonanni, Nikan Zargarzadeh, Ali Javinani, Scott A. Shainker, Anna M. Modest, George R. Saade, Kjersti Aagaard, Alireza A. Shamshirsaz

Department of Obstetrics & Gynecology Faculty Publications

Background

Placenta previa (PP) is a well-recognized obstetric complication with established maternal risks, particularly hemorrhage, that contribute significantly to maternal morbidity. In contrast, low-lying placenta (LLP) has historically been grouped with previa in both coding and clinical practice, limiting our ability to study its imparted associated outcomes as a distinct entity. However, in 2017, coding revisions allowed for a parsed diagnosis of LLP and PP and enabled the current study of differentiated associated outcomes.

Objectives

To describe and compare the independent rates of hemorrhage and severe maternal morbidity (SMM) associated with LLP and PP relative to normal placentation.

Methods

Orthodox Traditionalism In The Late 16th – Early 17th Century: The Religious-Anthropological Dimension, Olena Hudzenko, Olga Dobrodum

Occasional Papers on Religion in Eastern Europe

This article explores the religious-anthropological concepts in the works of Ukrainian thinkers of the late 16th and early 17th centuries. Formed in the context of Catholic expansion and intense confessional conflict, their ideas sought to preserve the Byzantine and Old Rus’ Orthodox tradition. Thinkers of this period emphasized the importance of safeguarding ancestral faith through a return to the principles of Holy Scripture, the foundational structures of early Christian doctrine, and the spiritual legacy of Kyivan Rus. These themes were especially prominent in the theological discourse of the so-called “Ostroh traditionalists,” centered around the Ostroh and Derman religious and cultural …

Pilgrims Of Hope: Sociotheological Considerations, András Máté-Tóth

Occasional Papers on Religion in Eastern Europe

Today, we can no longer view Europe according to the old political division between the progressive West and the lagging but striving East. Europe is a continent struggling with geopolitical challenges, a struggle in which it needs the offer of Christian thinking and behavior, which fully recognizes and acknowledges human beings and is capable of bridging the divides created by selfish interests. The bishops and episcopal institutions of Europe can humbly but confidently draw on the resources of faith and social knowledge, and with courageous consistency take their part in evangelization, journeying together in synodality with hope.

On The Chekist Front: Little-Known Pages Of The Life Of Ivan Voronaev (Agent "Nepliuev"), Founder Of Soviet Pentecostalism, Oleksandr Korotaiev

Occasional Papers on Religion in Eastern Europe

The figure of Ivan Voronaev (1885-1937), founder of the Soviet Pentecostal movement, occupies a contested place in the history of Eastern European Protestantism. Confessional narratives portray him as an “apostle of the Slavs” and martyr of faith, while Soviet anti-sectarian literature depicted him as a “bourgeois agent” and conduit of foreign influence. Despite their opposition, both approaches largely ignore the Chekist dimension of Voronaev’s biography–his systematic interaction with the Soviet security services and his role in their operational activities as a covert agent.

This article reconstructs previously marginalized episodes of Voronaev’s life on the basis of operational, investigative, and reporting …

The study demonstrates that religion in Ukraine serves as a factor of moral support, national unity, and spiritual resistance during wartime, while simultaneously remaining an arena of jurisdictional and identity …

The Religious Landscape Of Ukraine During The War: Consolidation Potential And Destructive Imitations, Vadym Dyiak

Occasional Papers on Religion in Eastern Europe

The article examines the transformation of religion’s functional role in the context of the russian-Ukrainian war. The author analyzes how the extreme circumstances of armed conflict catalyze the polarization of Ukraine’s religious landscape, clearly distinguishing between authentic religiosity and its ideological imitations. The main focus is on conceptualizing the differences between churches that serve as a resource for spiritual consolidation and social therapy (the OCU, the UGCC) and religious institutions that are used as instruments of hybrid aggression. To describe the latter phenomenon, the author introduces and adapts Oswald Spengler’s concept of “historical pseudomorphosis.” It is argued that the activities …
