    Telemedicine in monitoring pediatric LT patients before and during COVID-19 pandemic
    (Wiley, 2022) N/A; N/A; Musaoğlu, Miraç Nur; Yüksel, Muhammed; Mizikoğlu, Özlem; Arıkan, Çiğdem; PhD Student; Researcher; Other; Faculty Member; Koç University Research Center for Translational Medicine (KUTTAM) / Koç Üniversitesi Translasyonel Tıp Araştırma Merkezi (KUTTAM); Graduate School of Health Sciences; N/A; School of Medicine; School of Medicine; N/A; N/A; N/A; 240198
    Background: the delivery of healthcare services by telemedicine decreases costs of traveling for patients, is less time-consuming, and most importantly permits the connection between highly skilled specialists and patients. However, whether the use of telemedicine (text messaging) for LT patients was affected by the COVID-19 pandemic is unknown. Methods: We collected data (following consent from patients and parents) from 57 patients (33 male/24 female) with a median age of 47 (IQR: 9-91) months, whom we followed up with text messaging between September 2019 and September 2020, spanning the 6 months prior to COVID-19 and during this period. Results: in total, 723 text message mediated consultations occurred during this period, henceforth simply referred to as "messages." Three hundred and twenty-eight (45%) messages occurred during the 6 months up to the start of the pandemic. Following the COVID-19 outbreak, the number of messages increased to 395 (55%). the three most common reasons of messaging were post-liver-LT follow-up messages (n = 215/723, 29.7%), consultations for drug use (n = 157/723, 21.7%), and medication prescriptions (n = 113/723, 15.6%). Protocol biopsy discussions (n = 33/723, 4.6%) and fever (n = 27/723, 3.7%) were among others (vaccination, rash, diarrhea, cough, fatigue, Acne). During the COVID-19 outbreak, only post-LT follow-up messages increased significantly to 132/395 (33%) from 83/328 (25%) (p-value: .02). Conclusions: We found that the pandemic resulted in an increase in the total number of text message mediated consultations and specifically for the use of post-LT follow-up. Messaging was effective for post-LT follow-ups and all patients were at least satisfied.

    FKBP5 methylation, psychiatric disorders and stress: a systematic review and synthesis
    (Elsevier Science Inc, 2022) Çiçek, Yusuf; N/A; İzgi, Büşra; Kuvvet, Yasemin; Musaoğlu, Miraç Nur; Öztosun, Çınar; Eser, Hale Yapıcı; PhD Student; Master Student; PhD Student; Undergraduate Student; Faculty Member; Koç University Research Center for Translational Medicine (KUTTAM) / Koç Üniversitesi Translasyonel Tıp Araştırma Merkezi (KUTTAM); Graduate School of Health Sciences; Graduate School of Health Sciences; School of Medicine; School of Medicine; School of Medicine; N/A; N/A; N/A; N/A; 134359
    Background FKBP5 methylation levels are among the most studied epigenetic modifications related to psychiatric disorder vulnerability, however there are contradictory findings. We aimed to investigate the role of FKBP5 methylation in psychiatric disorders, in addition to its association with stress exposure (either life adversities, traumatic events or acute stress). Methods In accordance with PRISMA guidelines, ‘FKBP5’ and ‘methylation’ were searched in PubMed and Web of Science in March 2021. 330 studies were identified. Studies on non-psychiatric disorders, animal or cell lines were excluded. Type of study, sample size, sociodemographic properties of the participants, type of stress exposure, type of psychiatric disorder, CPG loci at FKBP5, and other related methods and covariates were extracted from 53 studies found to be eligible based on the inclusion criteria. Results Preliminary analysis showed that 19 studies investigated FKBP5 methylation in psychiatric disorders, 32 studies investigated the effects of stress types on FKBP5 methylation. Among the 197 CpG sites investigated, CpG at chr6:35,590,711 (intron 7), chr6:35,689,425 (promoter region), and chr6:35,590,736 (intron 7/GRE) sites were investigated by 26, 24, and 22 studies, respectively. CpG sites at chr6:35,590,736 and chr6:35,590,711 were reported to be linked to psychiatric disorder; CpG site at chr6:35,590,711, were reported to be linked to types of stress by more than half of the studies that investigated this region. Conclusions The studies on FKBP5 methylation and psychiatric disorder vulnerability are highly heterogeneous and most significant associations are found in intron 7. However, a great percentage of literature report insignificant associations of FKBP5 methylation sites with psychiatric disorder vulnerability.

    3D printed personalized magnetic micromachines from patient blood-derived biomaterials
    (American Association for the Advancement of Science (AAAS), 2021) Ceylan, Hakan; Doğan, Nihal Olcay; Yaşa, İmmihan Ceren; Department of Mechanical Engineering; Sitti, Metin; Musaoğlu, Miraç Nur; Kulalı, Zeynep Umut; Faculty Member; Department of Mechanical Engineering; College of Engineering; School of Medicine; 297104; N/A; N/A
    While recent wireless micromachines have shown increasing potential for medical use, their potential safety risks concerning biocompatibility need to be mitigated. They are typically constructed from materials that are not intrinsically compatible with physiological environments. Here, we propose a personalized approach by using patient blood-derivable biomaterials as the main construction fabric of wireless medical micromachines to alleviate safety risks from biocompatibility. We demonstrate 3D printed multiresponsive microswimmers and microrollers made from magnetic nanocomposites of blood plasma, serum albumin protein, and platelet lysate. These micro-machines respond to time-variant magnetic fields for torque-driven steerable motion and exhibit multiple cycles of pH-responsive two-way shape memory behavior for controlled cargo delivery and release applications. Their proteinaceous fabrics enable enzymatic degradability with proteinases, thereby lowering risks of long-term toxicity. The personalized micromachine fabrication strategy we conceptualize here can affect various future medical robots and devices made of autologous biomaterials to improve biocompatibility and smart functionality.
