Solute carrier organic anion (SLCO) transporters (OATP transporters) are involved in cellular uptake of drugs and hormones. Germline variants in SLCO1B3 and SLCO2B1 have been implicated in prostate cancer progression and therapy response, including to androgen deprivation and statin medications, but results have appeared heterogeneous. We conducted a cohort study of five single-nucleotide polymorphisms (SNPs) in SLCO1B3 and SLCO2B1 with prior evidence among 3208 men with prostate cancer who participated in the Health Professionals Follow-up Study or the Physicians' Health Study, following participants prospectively after diagnosis over 32 years (median, 14 years) for development of metastases and cancer-specific death (lethal disease, 382 events). Results were suggestive of, but not conclusive for, associations between some SNPs and lethal disease and differences by androgen deprivation and statin use. All candidate SNPs were associated with SLCO mRNA expression in tumor-adjacent prostate tissue. We also conducted a systematic review and harmonized estimates for a dose-response meta-analysis of all available data, including 9 further studies, for a total of 5598 patients and 1473 clinical events. The A allele of the exonic SNP rs12422149 (14% prevalence), which leads to lower cellular testosterone precursor uptake via SLCO2B1, was associated with lower rates of prostate cancer progression (hazard ratio per A allele, 0.80; 95% confidence interval, 0.69–0.93), with little heterogeneity between studies (I 2, 0.27). Collectively, the totality of evidence suggests a strong association between inherited genetic variation in SLCO2B1 and prostate cancer prognosis, with potential clinical use in risk stratification related to androgen deprivation therapy.

Li‐Fraumeni syndrome (LFS), a rare cancer predisposition syndrome caused by germline mutations in the TP53 gene, is associated with significant lifetime risk of developing cancer and warrants extensive and long‐term surveillance. There are psychosocial impacts on individuals and families living with this condition, from the initial diagnosis throughout multiple stages across the lifespan, but these impacts have not been systematically reviewed and organized. The objective of this scoping review was to synthesize and characterize the literature on psychosocial screening and outcomes, educational needs, support services, and available interventions for patients and families with LFS. A systematic search of six databases was most recently conducted in August 2020: (PubMed/MEDLINE (NLM), EMBASE (Elsevier), Cochrane Library (Wiley), CINAHL (EBSCO), PsycINFO (OVID), and Web of Science (Clarivate Analytics). A total of 15 757 titles were screened, and 24 articles included. Several important themes were identified across studies: factors associated with TP53 genetic testing, LFS surveillance, psychological outcomes, and communication. Findings related to these themes were organized into age‐specific categories (age agnostic/across the lifespan, childhood, adolescence and young adulthood, and adulthood). [ABSTRACT FROM AUTHOR]

Language and cultural barriers can impede communication between patients and clinicians, exacerbating health inequity. Additional complications can arise when family members, intending to protect their loved ones, ask clinicians to lie or not disclose to patients their diagnoses, prognoses, or intervention options. Clinicians must express respect for patients' and families' cultural, religious, and social norms regarding health care decision making, but they might also be ethically troubled by some decisions' effects on patients' health outcomes. This article suggests strategies for clinicians trying to overcome linguistic and cultural barriers to equitable patient care. [ABSTRACT FROM AUTHOR]

Objective: Akathisia is a neuropsychiatric syndrome characterized by subjective and objective restlessness. It is a common side effect in patients taking antipsychotics and other psychotropics. Patients with delirium are frequently treated with antipsychotic medications that are well known to induce akathisia as a side effect. However, the prevalence, phenomenology, and management of akathisia in patients with delirium remain largely unknown. The purpose of this review was to examine the medical literature in order to establish the current state of knowledge regarding the prevalence of antipsychotic-induced akathisia in patients with delirium.Method: A systematic review of the literature was conducted using the EMBASE, MEDLINE, PsycINFO, and CINAHL databases. Ten studies addressing the incidence of akathisia in patients taking antipsychotic medication for delirium were identified and included in our review.Results: The included studies reported a variable prevalence of antipsychotic-induced akathisia. A higher prevalence was found in patients taking haloperidol. Among atypical antipsychotics, paliperidone and ziprasidone were associated with a higher risk of akathisia. The risk for akathisia appeared to be a dose-related phenomenon.Significance Of Results: Studies using specific scales for evaluation of akathisia in delirium are lacking. Some populations, such as patients with cancer or terminally ill patients in palliative care settings taking antipsychotics for the treatment of delirium, could be at higher risk for development of akathisia as a side effect.
