RESUMO

INTRODUCTION: The use of telemedicine in oncology practice is rapidly expanding and is considered safe and cost effective. However, the implications of telemedicine on patient-physician interaction, patient satisfaction, and absence of the personal touch have not been studied to date. Following the spread of COVID-19, telemedicine services were rapidly incorporated at the Oncology Division of Tel Aviv Medical Center. We aimed to evaluate patients' perspectives and preferences regarding telemedicine and to assess whether this virtual communication platform affects the patient-physician relationship. METHODS: Between March 2020 and May 2020, adult cancer patients who conducted at least one successful telemedicine meeting were interviewed by trained medical personnel. The interview was based on validated patient satisfaction questionnaires and focused on patient-physician interaction in relation to the last in-patient visit. RESULTS: Of 236 patients, 172 (74%) patients agreed to participate. The study population comprised mainly patients with gastrointestinal malignancies (n = 79, 46%) with a median age of 63 years (range 21-88). The majority of patients were male (n = 93, 54%). Eighty-nine (51.7%) patients were receiving active oncologic treatment, and 58 (33.7%) were under routine surveillance following completion of active therapy. Almost all had a sense of secured privacy (n = 171, 96%), the majority of patients affirmed that their concerns were met (n = 166, 93%) and perceived that eye contact with the treating physician was perceived (n = 156, 87%). Only a minority felt that the absence of physical clinic visits harmed their treatment (n = 36, 20%). Most patients (n = 146, 84.9%) wished to continue telemedicine services. A multivariate analysis revealed that higher satisfaction and visits for routine surveillance were both predictors of willingness to continue future telemedicine meetings over physical encounters (odds ratio [OR] = 2.41, p = .01; OR = 3.34, p = .03, respectively). CONCLUSION: Telemedicine is perceived as safe and effective, and patients did not feel that it compromised medical care or the patient-physician relationship. Integration of telemedicine is ideal for patients under surveillance after completion of active oncologic treatment. Physician communication skills workshops are warranted with implementing this platform. IMPLICATIONS FOR PRACTICE: During the COVID-19 pandemic, telemedicine was rapidly implemented worldwide to facilitate continuity of quality care and treatment. Despite many potential setbacks, telemedicine has become a useful and safe tool for oncology practitioners to care for their patients. The use of telemedicine regarding patients' perspectives, emotions, and patient-physician communication in daily oncology practice has not been studied to date. This study demonstrated telemedicine is perceived as safe and effective and does not compromise medical care or the patient-physician relationship. Its use is ideal for surveillance after completion of active oncologic treatment. Physician communication skills workshops are warranted with implementing this platform.

RESUMO

Little is known about the effect of prematurity on later development of celiac disease (CD). We conducted a retrospective analysis of real-world data examining the association between very low birth weight (VLBW) prematurity and later development of CD autoimmunity (CDA) in 3580 infants born between years 2000 and 2012 and their matched controls. At a median of 12 years, VLBW prematurity was negatively associated with later development of CDA with a cumulative prevalence of 5.9 per 1000 versus 10.3 per 1000 (P = 0.02), though more former VLBW premature infants were ever tested for CDA (48.5% vs 37.4%, P < 0.001). The odds ratio for developing CDA among children born preterm at VLBW was 0.57 (95% confidence interval (CI) 0.35-0.92) as compared with matched controls. There was no difference in clinical characteristics of CDA between both groups. In conclusion, VLBW preterm infants present a decreased risk for the development of CDA during childhood and adolescence.

RESUMO

PURPOSE: Traditionally, pathologists have been branded the doctor's doctor, with a position behind the microscope and limited interaction among patients, despite their rich understanding of disease development and ability to navigate personalized medicine in an era of dynamic molecular testing. METHODS: We piloted a unique patient-pathology consultation service, whereby pathologists review tissue specimens with oncology patients, facilitating a platform for heightening patient understanding of their disease and guiding additional genetic and molecular evaluation. We conducted a retrospective survey assessing patient experience. RESULTS: Fifty-nine patients participated in the patient-pathology clinic consultation, with a median age of 64 years and a female predominance (33, 55.9%). The majority of patients were treated for sarcomas (11, 18.6%), breast cancer (10, 17%), and GI tumors (10, 17%). Half of the participants consulted regarding a metastatic disease (28, 47.5%). Thirty patients (50.8%) were referred to additional workup, 11 patients (18.6%) to a second opinion, and 25 participants (42.4%) were counseled to complete genetic sequencing or additional molecular profiles on their pathologic samples. Twelve patients (20.3%) were referred for pathology revision within our institution. Three patients (5.1%) had a change in treatment plan resulting from the clinic visit. The majority (90%) would recommend the patient-pathology clinic to other oncology patients. CONCLUSION: To our knowledge, this is the largest study of patient-pathologist consultation services implemented at a single institution. Our work suggests that the program may provide effective patient understanding and reinforce the role of the pathologist as the patient's doctor. This work surfaced the concerns of patients, regarding their pathology reports, and demonstrated that the patient-pathology clinics are a valuable platform to address patients' distress regarding uncertainty of their diagnosis and an integral resource engaging directly with patients, driving additional evaluation and patient-targeted treatment.

RESUMO

As the endothelial-to-mesenchymal transition (EndMT) supports the pro-angiogenic and invasive characteristics of glioblastoma multiforme (GBM), blocking this process would be a promising approach to inhibit tumor progression and recurrence. Here, we demonstrate that glioma stem cells (GSC) induce EndMT in brain endothelial cells (BEC). TGF-ß signaling is necessary, but not sufficient to induce this EndMT process. Cell-to-cell contact and the contribution of Notch signaling are also required. NEO212, a conjugate of temozolomide and perillyl alcohol, blocks EndMT induction and reverts the mesenchymal phenotype of tumor-associated BEC (TuBEC) by blocking TGF-ß and Notch pathways. Consequently, NEO212 reduces the invasiveness and pro-angiogenic properties associated with TuBEC, without affecting control BEC. Intracranial co-implantation of BEC and GSC in athymic mice showed that EndMT occurs in vivo, and can be blocked by NEO212, supporting the potential clinical value of NEO212 for the treatment of GBM.

RESUMO

Glioblastoma (GBM) is a highly aggressive primary brain tumor with a poor prognosis. Treatment with temozolomide, standard of care for gliomas, usually results in drug resistance and tumor recurrence. Therefore, there is a great need for drugs that target GBM. NEO214 was generated by covalently linking rolipram to perillyl alcohol (POH) via a carbamate bond to form the rolipram-perillyl alcohol conjugate. We show here that NEO214 is effective against both temozolomide-sensitive and temozolomide-resistant glioma cells. Furthermore, NEO214 is effective for different mechanisms of temozolomide resistance: overexpression of MGMT (O6-methylguanine methyl-transferase); deficiency in specific mismatch repair proteins; and overexpression of base excision repair (BER) proteins. NEO214-induced cytotoxicity involves apoptosis triggered by endoplasmic reticulum (ER) stress, as well as activating the Death Receptor 5 (DR5)/TNF-related apoptosis-inducing ligand (TRAIL/Apo2L) pathway. In vitro studies show that glioma cells treated with NEO214 express DR5 and exhibit cell death in the presence of recombinant TRAIL, a growth factor constitutively produced by astrocytes. Our in vitro 3D coculture data show that induction of DR5 in glioma cells with NEO214 and TRAIL cause tumor cell death very effectively and specifically for glioma cells. In vivo studies show that NEO214 has antitumor efficacy in orthotropic syngeneic rodent tumor models. Furthermore, NEO214 has therapeutic potential especially for brain tumors because this drug can cross the blood-brain barrier (BBB), and is effective in the TRAIL-rich astrocyte microenvironment. NEO214 is a strong candidate for use in the treatment of GBMs.
