Fertility preservation in reproductive-aged female patients with colorectal cancer: a scoping review.

BACKGROUND: Colorectal cancer (CRC) incidence in adults younger than 50 years is steadily increasing in the USA, and treatment for CRC can impact future fertility. However, fertility decision-making in female patients with CRC can be complex, with fertility preservation (FP) counseling occurring inconsistently. PURPOSE: The goal of this scoping review was to assess the literature regarding the frequency and quality of fertility preservation (FP) discussions taking place among oncology clinicians and their reproductive-age female patients with colorectal cancer (CRC) in order to identify existing gaps in care and inform future research, interventions, or potential changes in practice. METHODS: A comprehensive literature search was conducted using the Ovid Medline, PsycInfo, and Scopus databases in order to identify studies pertaining to FP counseling in reproductive-age female patients with CRC. We used Covidence to screen studies for relevance and to extract data. Findings of interest included rate of fertility and/or FP discussions, patient characteristics associated with fertility discussions, initiators of discussions, rate of referrals to fertility specialists, patient utilization of FP services, and unmet fertility needs. We performed both quantitative and qualitative data synthesis. RESULTS: We identified five studies that met our inclusion criteria, all published between 2007 and 2022. Frequency of fertility counseling discussions was low across studies, with a range of 15 to 52.5% of female patients with CRC receiving counseling. Patient characteristics which may be associated with likelihood of fertility discussion included age, parity, number of children, cancer location and stage, treatment type, and quality of life. The literature suggested that fertility discussions were initiated by clinicians about two-thirds of the time, and medical oncologists were the clinicians most likely to initiate. Studies did capture unmet fertility-related patient needs; participants who did not receive counseling often expressed desire for these discussions and regret that they did not occur. CONCLUSION: Despite increasing incidence of CRC in patients at younger ages, this scoping review found a dearth of research conducted on young female CRC patients' experiences with fertility counseling and referrals. Notably, the existing research reveals that relatively few of these patients are receiving appropriate counseling. Additional research is needed to clarify current FP counseling practices, patient and clinician perceptions about FP, and ways to improve the quantity and quality of FP counseling in this patient population.

Understanding Retention in the HIV Pre-Exposure Prophylaxis Cascade Among Cisgender Women.

HIV remains a significant public health concern in the United States, with 34,800 new cases diagnosed in 2019; of those, 18% were among women. Oral pre-exposure prophylaxis (PrEP) with daily tenofovir disoproxil fumarate/emtricitabine is effective and safe, reducing HIV transmission by up to 92% in women. Though studies demonstrate low rates of PrEP adherence among cisgender women prescribed oral PrEP, little is known about the factors that shape PrEP continuation among them. This study focuses on understanding the experiences of cisgender women who have initiated PrEP to gain insight into the factors that shape PrEP continuation. We conducted semi-structured interviews with (N = 20) women who had been prescribed oral PrEP. Interviews were guided by the social-ecological framework to identify multilevel factors affecting PrEP continuation; we specifically examined the experience of engagement and retention in the PrEP cascade. We recruited women who had been prescribed oral PrEP by a government-sponsored sexual health center or a hospital-based family planning clinic in Washington, DC. Factors facilitating PrEP continuation included a positive emotional experience associated with PrEP use, high perceived risk of HIV acquisition, and high-quality communication with health care providers. The most common reason for PrEP discontinuation was low perceived HIV risk (n = 11). Other factors influencing discontinuation were side effects, a negative emotional experience while using PrEP, and negative interactions with the health care system. This study underscores the importance of specific multi-level factors, including the provision of high-quality communication designed to resonate with women and shared decision making between women and their health care providers.

Molecular Imaging of Opioid and Dopamine Systems: Insights Into the Pharmacogenetics of Opioid Use Disorders.

Opioid use in the United States has steadily risen since the 1990s, along with staggering increases in addiction and overdose fatalities. With this surge in prescription and illicit opioid abuse, it is paramount to understand the genetic risk factors and neuropsychological effects of opioid use disorder (OUD). Polymorphisms disrupting the opioid and dopamine systems have been associated with increased risk for developing substance use disorders. Molecular imaging studies have revealed how these polymorphisms impact the brain and contribute to cognitive and behavioral differences across individuals. Here, we review the current molecular imaging literature to assess how genetic variations in the opioid and dopamine systems affect function in the brain's reward, cognition, and stress pathways, potentially resulting in vulnerabilities to OUD. Continued research of the functional consequences of genetic variants and corresponding alterations in neural mechanisms will inform prevention and treatment of OUD.

Brain Imaging of Taste Perception in Obesity: a Review.

PURPOSE OF REVIEW: We summarize neuroimaging findings related to processing of taste (fat, salt, umami, bitter, and sour) in the brain and how they influence hedonic responses and eating behaviors and their role in obesity. RECENT FINDINGS: Neuroimaging studies in obese individuals have revealed alterations in reward/motivation, executive control/self-regulation, and limbic/affective circuits that are implicated in food and drug addiction. Psychophysical studies show that sensory properties of food ingredients may be associated with anthropometric and neurocognitive outcomes in obesity. However, few studies have examined the neural correlates of taste and processing of calories and nutrient content in obesity. The literature of neural correlated of bitter, sour, and salty tastes remains sparse in obesity. Most published studies have focused on sweet, followed by fat and umami taste. Studies on calorie processing and its conditioning by preceding taste sensations have started to delineate a dynamic pattern of brain activation associated with appetition. Our expanded understanding of taste processing in the brain from neuroimaging studies is poised to reveal novel prevention and treatment targets to help address overeating and obesity.
