Geriatric assessment-guided interventions for older adults with multiple myeloma: A feasibility and acceptability study.

INTRODUCTION: Geriatric assessment (GA)-guided supportive care programs have been successful in improving treatment outcomes for older adults with solid-organ cancers. This study aimed to evaluate the feasibility of a GA-guided supportive care program among older adults treated for multiple myeloma (MM). MATERIALS AND METHODS: The study utilized an existing registry of adults with plasma cell disorders at the University of North Carolina. Patients with MM, aged 60 or older, and having a GA-identified deficit in one or more problem area were offered referrals to supportive care resources during routine visits. Problem areas included physical function deficits, polypharmacy, and anxiety or depression. Patients with physical function deficits were offered referral to physical therapy (PT), those with polypharmacy to an Oncology Clinical Pharmacist Practitioner (CPP), and those with mental health symptoms to the Comprehensive Cancer Support Program (CCSP). RESULTS: Of the 58 individuals identified as having at least one deficit on the GA, PT was the most commonly identified relevant resource (79%), followed by CPP visits (57%). Among individuals that were offered referral(s) to at least one new supportive care resource, the acceptance rate was 50%. Referral acceptance rates were highest among those recommended for a CPP visit (55% of those approached) and lowest for CCSP (0%). DISCUSSION: The study examined the feasibility and acceptability of a referral program for supportive care resources among older adults with MM who have deficits on GA. The most commonly identified deficit was physical functioning, followed by polypharmacy and mental health. The study found that physical interventions and referrals to CPPs were the most accepted interventions. However, the low proportion of patients who accepted physical therapy referrals indicates the need for tailored and more personalized approaches. Further research is needed to explore the feasibility and impact of supportive care referral programs for older adults with MM.

Cerebral palsy and the placenta: A review of the maternal-placental-fetal origins of cerebral palsy.

Accumulating evidence from clinical and neuropathological study has identified a number of seemingly disparate associations carrying a predisposition for cerebral palsy (CP). We narratively reviewed clinical studies reporting associations between prenatal and perinatal environmental factors and the risk of developing CP. As expected, some processes with direct central nervous system involvement (e.g. perinatal hypoxic-ischemic encephalopathy or infectious encephalomalacia) carry >10% absolute risk of CP. Other acute perinatal processes including placental abruption, uterine rupture, and neonatal sepsis are also associated with increased risk of CP but carry <3% absolute risk of CP. Indirect markers of chronic placental insufficiency such as fetal and placental growth patterns are associated with increased risk of CP, and risk of CP in infants with growth abnormalities born extremely preterm exceeds 10%. We synthesize these findings within a framework of risk accumulating across several defined pre- and perinatal developmental windows. Causal links remain incompletely understood, but genetic background, the intrauterine environment, general fetal health, and fetal neurologic health all appear to contribute.

Thyroid hormone signaling promotes hepatic lipogenesis through the transcription factor ChREBP.

Thyroid hormone (TH) action is essential for hepatic lipid synthesis and oxidation. Analysis of hepatocyte-specific thyroid receptor ß1 (TRß1) knockout mice confirmed a role for TH in stimulating de novo lipogenesis and fatty acid oxidation through its nuclear receptor. Specifically, TRß1 and its principal corepressor NCoR1 in hepatocytes repressed de novo lipogenesis, whereas the TH-mediated induction of lipogenic genes depended on the transcription factor ChREBP. Mice with a hepatocyte-specific deficiency in ChREBP lost TH-mediated stimulation of the lipogenic program, which, in turn, impaired the regulation of fatty acid oxidation. TH regulated ChREBP activation and recruitment to DNA, revealing a mechanism by which TH regulates specific signaling pathways. Regulation of the lipogenic pathway by TH through ChREBP was conserved in hepatocytes derived from human induced pluripotent stem cells. These results demonstrate that TH signaling in the liver acts simultaneously to enhance both lipogenesis and fatty acid oxidation.
