JMIR Mhealth Uhealth 2021 Jul 8;9(7):e29619. Epub 2021 Jul 8.

Division of Pediatric Hematology, Oncology, Neuro-Oncology & Stem Cell Transplantation, Ann & Robert H Lurie Children's Hospital of Chicago, Chicago, IL, United States.

Background: Telemedicine, including video-, web-, and telephone-based interventions, is used in adult and pediatric populations to deliver health care and communicate with patients. In the realm of hematology, telemedicine has recently been used to safely and efficiently monitor treatment side-effects, perform consultations, and broaden the reach of subspecialty care.

Objective: We aimed to synthesize and analyze information regarding the feasibility, acceptability, and potential benefits of telemedicine interventions in malignant and nonmalignant hematology, as well as assess the recognized limitations of these interventions.

Methods: Studies were identified through a comprehensive Medical Subject Headings (MeSH) search on the PubMed MEDLINE, Controlled Register of Clinical Trials (Cochrane CENTRAL from Wiley), Embase, and CINAHL (EBSCO) databases on February 7, 2018. A second search, utilizing the same search strategy, was performed on October 1, 2020. We followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines in the reporting of included evidence. Included studies were original articles researching the feasibility, acceptability, and clinical outcomes of telemedicine or telehealth interventions in pediatric or adult populations with malignant or nonmalignant hematological conditions. Data items in the extraction form included first author name, publication year, country, malignant or nonmalignant hematological condition or disease focus of the study, participant age, participant age subgroup (pediatric or adult), study design and setting, telemedicine intervention type and description, study purpose, and main study outcomes.

Results: A total of 32 articles met the preset criteria and were included in this study. Most (25/32) studies were conducted in adults, and the remaining (7/32) were conducted in the pediatric population. Of the 32 studies, 12 studied malignant hematological conditions, 18 studied nonmalignant conditions, and two studied both malignant and nonmalignant conditions. Study types included pilot study (11/32), retrospective study (9/32), randomized controlled trial (6/32), cross-sectional study (2/32), case study (1/32), pre-post study (1/32), noncomparative prospective study (1/32), and prospective cohort study (1/32). The three main types of telemedicine interventions utilized across all studies were video-based (9/32), telephone-based (9/32), and web-based interventions (14/32). Study results showed comparable outcomes between telemedicine and traditional patient encounter groups across both pediatric and adult populations for malignant and nonmalignant hematological conditions.

Conclusions: Evidence from this review suggests that telemedicine use in nonmalignant and malignant hematology provides similar or improved health care compared to face-to-face encounters in both pediatric and adult populations. Telemedicine interventions utilized in the included studies were well received in both pediatric and adult settings. However, more research is needed to determine the efficacy of implementing more widespread use of telemedicine for hematological conditions.

Adherence to Immunosuppression Medications among Heart Transplant Recipients: Challenges, Opportunities, and Potential Role of Digital Approaches in the COVID-19 Era.

J Cardiovasc Dev Dis 2021 Jun 10;8(6). Epub 2021 Jun 10.

Department of Pediatrics, Northwestern University Feinberg School of Medicine, Chicago, IL 60611, USA.

Society and medical practice have been restructured dramatically to avoid further spread of the COVID-19 virus; telehealth/telemedicine, mask wearing, and nationwide social distancing practices have become widespread. However, we still face unprecedented challenges in fields where patients require frequent and active follow-up visits for monitoring, including that of solid-organ transplant, and in particular, heart transplant. Adherence to immunosuppression remains a unique challenge in heart transplantation, especially during the COVID-19 pandemic. Failure to adhere to immunosuppression can have disastrous consequences, including graft rejection and death. In this article, we discuss challenges related to adherence to immunosuppression medications among heart transplant recipients, as well as opportunities to leverage digital approaches and interventions to monitor and optimize adherence behavior and health outcomes in this population.

Novel promising reproductive and metabolic effects of Cicer arietinum L. extract on letrozole induced polycystic ovary syndrome in rat model.

J Ethnopharmacol 2021 Oct 7;278:114318. Epub 2021 Jun 7.

Ethnopharmacological Relevance: Chickpea was used in both greek and indian traditional medicine for hormonal related conditions as menstrual induction, acceleration of parturation, treatment of retained placenta and stimulation of lactation. Chickpea (Cicer arietinum) sprout isoflavone isolates exhibited reasonable estrogenic activities. Isoflavones, a subtype of phytoestrogens, are plant derivatives with moderate estrogenic activity that tend to have protective effects on hormonal and metabolic abnormalities of women with polycystic ovary syndrome (PCOS).

Aim Of The Study: In this study, we investigated the effect of UPLC/ESI-MS characterized Cicer arietinum L. seeds ethanol extract (CSE) on ovarian hormones, oxidative response and ovarian histological changes on induced PCOS rat model.

Materials And Methods: Thirty-five rats were divided into five groups including negative control, PCOS, and treatment groups. PCOS was induced using letrozole (1 mg/kg) daily orally for 21 days. Each treatment group was treated with one of the following for 28 days after induction of PCOS: clomiphene citrate (1 mg/kg), and CSE at 250 and 500 mg/kg. Ovaries and uteri were excised, weighed and their sections were used for quantitative real-time reverse transcriptase polymerase chain reaction, antioxidant assays and histomorphometric study of the ovaries. The antioxidant assays, histopathological examination, hormonal and metabolic profiles, and Cyp11a1(steroidogenic enzyme) mRNA expression were measured.

Results: In all treatment groups, ovarian weight was significantly decreased despite having no significant effect on uterine weight. Histomorphometric study in the treatment groups revealed a significant decrease in the number and diameter of cystic follicles, a significant increase in granulosa cell thickness while, thickness of theca cells was significantly decreased when compared to PCOS. Hormone levels, metabolic profile and antioxidant status were improved in the treatment groups. Moreover, Cyp11a1 mRNA expression was significantly downregulated in the treatment groups compared to PCOS.

Conclusions: In the current study, CSE enhanced the reproductive and metabolic disorders which were associated with PCOS induction. For the first time, we have highlighted the effect of CSE in treating PCOS and its associated manifestations.

Linum usitatissimum seeds oil down-regulates mRNA expression for the steroidogenic acute regulatory protein and Cyp11A1 genes, ameliorating letrezole-induced polycystic ovarian syndrome in a rat model.

J Physiol Pharmacol 2021 Feb 3;72(1). Epub 2021 Jun 3.

Department of Physiology, Faculty of Veterinary Medicine, Cairo University, Giza, Egypt.

The safety and effectiveness of nutricetics suggest that they may offer an alternative to pharmaceutical and surgical therapy for hormone-dependent disorders, such as polycystic ovarian syndrome (PCOS). We investigated the effects of Linum usitatissimum seed oil (LSO) on ovarian functionality, its molecular targets, and the oxidative response in hyperandrogenism-induced polycystic ovary. The composition of LSO has been analyzed using ultra-performance liquid chromatography-electrospray ionization-tandem mass spectrometry (UPLC-ESI-MS). A well-established PCOS rat model orally administered with letrozole daily for 21 days was used to investigate the effect of LSO at doses of 1 and 2 mL/kg body weight for 28 days. The effect on hormonal profile and antioxidant status, histopathology (cell proliferation), and the expression ratio of the steroidogenic acute regulatory protein (StAR) and Cyp11A1 gene were evaluated. LSO exerted beneficial effects on PCOS rat models via restoring glutathione (GSH), malondialdehyde (MDA), beta subunit subunit luteinizing hormone (LH), testosterone levels, and histopathological scoring. Furthermore, LSO reversed the elevated StAR and Cyp11A1 genes in the PCOS rat model. This study demonstrated the molecular and cellular mechanisms of the beneficial effect of LSO against the reproductive and metabolic disorders of PCOS.
