Article Synopsis
  • Standard information reporting is essential for consistent assay conditions and data, enabling easier comparisons between laboratories.
  • The publication presents the Minimum Information for Reporting on the TEER assay (MIRTA), a key method used to assess cell culture models and toxicity potential.
  • Developed through an international collaboration, the recommendations from the RespTox Collaborative aim to improve data transparency, reproducibility, and quality in both respiratory and other cell systems.

Purpose: To elucidate the long-term impacts of hearing loss, tinnitus and balance in people living with and beyond cancer (LWBC) treated with platinum-based chemotherapy (PBCT).

Methods: A literature search was conducted between March and June 2022 using PubMed, Web of Science and Google Scholar. Full-text papers in English were included.

Purpose: This study aimed to explore the burden of inner ear damage (ototoxicity) on adults living with and beyond cancer treated with chemotherapy and  the impact on their quality of life (QoL). Furthermore, this study aimed to explore patient awareness surrounding chemotherapy-induced inner ear damage, known as ototoxicity, and assess what support they had been offered.

Methods: Participants were adults who had undergone chemotherapy, recruited from cancer clinics, charities and social media.

Article Synopsis
  • * Research identified changes in metabolic pathways related to amino acids, glucose, and the TCA cycle in BAT when exposed to cold, using transcriptome and metabolome analysis.
  • * The study found that glucose uptake and processing in mitochondria, specifically through the MPC1 protein, are critical for effective thermogenesis, with alternative fuel sources like ketogenesis compensating when glucose metabolism is impaired.

To identify any change in quality of life (QoL) caused by chemotherapy-induced toxicities, such as hearing loss and tinnitus, to provide information in order to improve services and aid clinicians in their decision-making. This systematic review followed the preferred reporting items for systematic reviews and meta-analysis (PRISMA) checklist. The search terms were cancer, platinum-based chemotherapy, ototoxicity and "quality of life".

Article Synopsis
  • Prolonged cold exposure leads to the activation of beige fat cells, which are crucial for burning energy and generating heat through mitochondria.
  • The study reveals that the protein TLE3 plays a key role by inhibiting the expression of mitochondrial genes in these beige adipocytes, thereby affecting their function.
  • Blocking TLE3 could be a potential new treatment strategy for obesity and diabetes, as it enhances the cells' ability to metabolize energy and improve glucose levels.

Background: Many cancer patients and survivors experience permanent and life-debilitating effects, such as ototoxicity, from treatment. Ototoxicity manifests as high-frequency hearing loss and tinnitus, which can have a detrimental effect on the quality of life (QoL) of those affected. Currently, there is little information and support offered to these patients who experience ototoxicity, potentially leading to many being undiagnosed and untreated.

Cochleotoxicity following the treatment with platinum-based chemotherapy is well documented. The potential for vestibulotoxicity is still unclear. This scoping review examined the extent of current research literature, summarized research findings and identified research gaps regarding vestibular-related adverse effects associated with platinum-based chemotherapy in survivors of cancer.

Yoga has been shown to improve cancer survivors' quality of life, yet regular yoga practice is a challenge for those who are sedentary. We conducted a pilot randomized controlled study to assess feasibility and adherence of two types of yoga intervention among sedentary cancer survivors. Sedentary breast and ovarian cancer survivors were randomized to practice either restorative yoga (minimal physical exertion, Group R) or vigorous yoga (considerable physical exertion, Group V) in three 60-minute supervised sessions a week for 12 weeks, followed by 12 weeks of home practice.

Background: Several factors have been shown to influence first-time pass rates on the National Physical Therapy Examination (NPTE). It is unclear to what extent academic difficulty experienced by students in a physical therapist education program may affect NPTE pass rates. The effects of institutional status (public or private) and Carnegie Classification on NPTE pass rates also are unknown.

Objective: The purpose of this study was to assess the outcome after transabdominal-cerclage placement during pregnancy in women with previous unsuccessful transvaginal cerclage.

Study Design: We conducted a retrospective case series that described pregnancy outcome in women who were treated with transabdominal cerclage between 1994 and 2006.

Results: Seventy-five women with negative evaluation for recurrent pregnancy loss and > or = 1 previous unsuccessful transvaginal cerclage procedures were treated with transabdominal cerclage.

The IGF-II gene normally exhibits genomic imprinting, a DNA modification that allows the expression of only one of the two inherited alleles. With loss of imprinting, there is a gain of allelic gene expression (GOAGE) due to IGF-II being expressed by both alleles. GOAGE for IGF-II has been demonstrated in a number of malignancies and in normal epithelia surrounding malignancies, but not in epithelia without associated neoplasia.

Cyclooxygenase-2 (COX-2) has been linked to neoplastic progression in Barrett's esophagus. Acid exposure has been shown both to activate the MAPK pathways and to increase COX-2 protein expression in Barrett's metaplasia, but it is not known whether these effects are interrelated. We hypothesized that acid-induced activation of the MAPK pathways mediates an increase in COX-2 expression in Barrett's esophagus, and we tested this hypothesis in a Barrett's-associated adenocarcinoma cell line (SEG-1).
