Vega JN, Albert KM, Mayer IA, Taylor WD, Newhouse PA
(2019) J Cancer Surviv 13: 673-686
MeSH Terms: Adult, Aged, Aged, 80 and over, Antineoplastic Combined Chemotherapy Protocols, Cancer Survivors, Cognition, Cognitive Dysfunction, Female, Humans, Male, Middle Aged, Neoplasms, Nicotine, Pilot Projects, Quality of Life, Self Report, Survivors, Transdermal Patch
Show Abstract · Added March 3, 2020
PURPOSE - Persistent chemotherapy-related cognitive impairment (pCRCI) is commonly reported following cancer treatment and negatively affects quality of life; however, there is currently no pharmacological treatment indicated for pCRCI. This pilot study obtained preliminary data regarding the use of transdermal nicotine patches as a therapeutic strategy for women with pCRCI to (1) reduce subjective cognitive complaints and (2) enhance objective cognitive performance in breast, colon, lymphoma, or ovarian cancer survivors with pCRCI.
METHODS - Participants were randomized to either placebo (n = 11) or transdermal nicotine (n = 11) for 6 weeks, followed by 2 weeks of treatment withdrawal for a total of 8 weeks. Participants were assessed using both subjective and objective measures of cognitive functioning at five visits before, during, and after treatment.
RESULTS - Over the course of the study, women in both groups improved substantially in severity of self-reported cognitive complaints measured by Functional Assessment of Cancer Therapy-Cognitive Function Perceived Cognitive Impairments regardless of treatment arm. Additionally, objective cognitive performance measures improved in both groups; however, there was no significant difference in improvement between groups.
CONCLUSIONS - Due to a large placebo response, we were unable to determine if a drug effect was present. However, we did observe substantial improvement in self-reported cognitive symptoms, likely resulting from factors related to participation in the trial rather than specific drug treatment effects.
TRIAL REGISTRATION - The study was registered with clinicaltrials.gov (trial registration: NCT02312943).
IMPLICATIONS FOR CANCER SURVIVORS - These results suggest that women with pCRCI can exhibit improvement in subjective cognition, with attention paid to symptoms and close follow-up over a short period of time.

Self-reported Sensory Hypersensitivity Moderates Association Between Tactile Psychophysical Performance and Autism-Related Traits in Neurotypical Adults.
Bryant LK, Woynaroski TG, Wallace MT, Cascio CJ
(2019) J Autism Dev Disord 49: 3159-3172
MeSH Terms: Adult, Autism Spectrum Disorder, Female, Humans, Male, Phenotype, Self Report, Touch
Show Abstract · Added March 18, 2020
Atypical responses to tactile stimulation have been linked to core domains of dysfunction in individuals with autism spectrum disorder (ASD) and phenotypic traits associated with ASD in neurotypical individuals. We investigated (a) the extent to which two psychophysically derived measures of tactile sensitivity-detection threshold and dynamic range-relate to traits associated with ASD and (b) whether those relations vary according to the presence of self-reported sensory hypersensitivities in neurotypical individuals. A narrow dynamic range was associated with increased autism-related traits in individuals who reported greater sensory hypersensitivity. In contrast, in individuals less prone to sensory hypersensitivity, a narrow dynamic range was associated with reduced autism-related traits. Findings highlight the potential importance of considering dynamic psychophysical metrics in future studies.

Show Abstract · Added July 17, 2019
PURPOSE - Cisplatin, a commonly used chemotherapeutic, results in tinnitus, the phantom perception of sound. Our purpose was to identify the clinical and genetic determinants of tinnitus among testicular cancer survivors (TCS) following cisplatin-based chemotherapy.
EXPERIMENTAL DESIGN - TCS ( = 762) were dichotomized to cases (moderate/severe tinnitus; = 154) and controls (none; = 608). Logistic regression was used to evaluate associations with comorbidities and SNP dosages in genome-wide association study (GWAS) following quality control and imputation (covariates: age, noise exposure, cisplatin dose, genetic principal components). Pathway over-representation tests and functional studies in mouse auditory cells were performed.
RESULTS - Cisplatin-induced tinnitus (CisIT) significantly associated with age at diagnosis ( = 0.007) and cumulative cisplatin dose ( = 0.007). CisIT prevalence was not significantly greater in 400 mg/m-treated TCS compared with 300 ( = 0.41), but doses >400 mg/m (median 580, range 402-828) increased risk by 2.61-fold ( < 0.0001). CisIT cases had worse hearing at each frequency (0.25-12 kHz, < 0.0001), and reported more vertigo (OR = 6.47; < 0.0001) and problems hearing in a crowd (OR = 8.22; < 0.0001) than controls. Cases reported poorer health ( < 0.0001) and greater psychotropic medication use (OR = 2.4; = 0.003). GWAS suggested a variant near (rs7606353, = 2 × 10) and eQTLs were significantly enriched independently of that SNP ( = 0.018). overexpression in HEI-OC1, a mouse auditory cell line, resulted in resistance to cisplatin-induced cytotoxicity. Pathway analysis implicated potassium ion transport (q = 0.007).
CONCLUSIONS - CisIT associated with several neuro-otological symptoms, increased use of psychotropic medication, and poorer health. , expressed in the cochlear lateral wall, was implicated as protective. Future studies should investigate otoprotective targets in supporting cochlear cells.

Self-reported Cannabis Use and Changes in Body Mass Index, CD4 T-Cell Counts, and HIV-1 RNA Suppression in Treated Persons with HIV.
Lee JT, Saag LA, Kipp AM, Logan J, Shepherd BE, Koethe JR, Turner M, Bebawy S, Sterling TR, Hulgan T
(2020) AIDS Behav 24: 1275-1280
MeSH Terms: Adult, Anti-HIV Agents, Antiretroviral Therapy, Highly Active, Body Mass Index, CD4 Lymphocyte Count, CD4-Positive T-Lymphocytes, Cannabis, Female, HIV Infections, HIV-1, Humans, Male, Marijuana Smoking, RNA, Retrospective Studies, Self Report, Viral Load
Show Abstract · Added December 11, 2019
Cannabis use is prevalent among HIV-positive persons, but evidence regarding the impact of cannabis in HIV-positive persons is limited. We conducted a retrospective cohort study of HIV-positive adults initiating their first antiretroviral therapy (ART) regimen. A dedicated intake form assessed self-reported cannabis use in the preceding 7 days at each visit. The relationships between time-varying cannabis use and body mass index (BMI), CD4+ T-cell count, and HIV-1 RNA levels were assessed using random effects models adjusted for age, sex, race, and other reported substance use. 4290 patient-visits from 2008 to 2011 were available from 1010 patients. Overall, there were no statistically significant differences in CD4+ T-cell count and BMI across multiple adjusted models using different measures of cannabis use (ever use during the study period, any use, and number of times used in the preceding 7 days). Cannabis use by all three measures was associated with greater odds of having a detectable viral load at a given visit than no reported use (OR 2.02, 1.72, and 1.08, respectively; all adjusted p < 0.05). Self-reported cannabis use was not associated with changes in BMI or CD4+ T-cell count in ART-naïve HIV-positive persons starting treatment. However, reported cannabis use by multiple categories was associated with having a detectable HIV-1 RNA during the study period. Associations between cannabis use, adherence, and HIV-related outcomes merit further study.

Posttraumatic Stress Symptoms Mediate the Effects of Trauma Exposure on Clinical Indicators of Central Sensitization in Patients With Chronic Pain.
McKernan LC, Johnson BN, Crofford LJ, Lumley MA, Bruehl S, Cheavens JS
(2019) Clin J Pain 35: 385-393
MeSH Terms: Adult, Central Nervous System Sensitization, Chronic Pain, Female, Humans, Male, Middle Aged, Self Report, Stress Disorders, Post-Traumatic, Surveys and Questionnaires
Show Abstract · Added March 25, 2020
OBJECTIVE - Evidence supports high rates of co-occurrence of posttraumatic stress disorder (PTSD) and chronic pain disorders involving central sensitization (CS). The nature of this relationship, however, remains relatively unexplored. In this study, we aimed to (1) assess how both trauma exposure and current PTSD symptoms are related to clinical manifestations of CS, and (2) test whether PTSD symptoms explain the relationship between trauma exposure and CS. Because experiential avoidance has been shown to impact the relationship between trauma and health outcomes, we (3) explored experiential avoidance as a possible mediator or moderator of the trauma-CS relationship.
METHODS - A sample of 202 adult patients (79% female) with chronic pain completed validated self-report measures of trauma exposure, current PTSD symptoms, experiential avoidance, and 3 manifestations of CS: widespread pain, greater pain severity, and polysomatic symptom reporting. We used path analysis and multivariate regression to assess our study aims.
RESULTS - Both trauma exposure and PTSD symptoms were significantly associated with all 3 clinical indicators of CS. PTSD symptoms partially explained the relationship between trauma exposure and widespread pain, pain intensity, and polysomatic symptoms. Experiential avoidance did not mediate or moderate the trauma-CS relationship.
CONCLUSIONS - Our findings suggest that trauma exposure is linked to elevated clinical markers of CS but a critical factor in this relationship is the mediating effect of current PTSD symptoms.

MeSH Terms: Adult, Aged, China, Feeding Behavior, Female, Follow-Up Studies, Humans, Kidney Calculi, Male, Middle Aged, Proportional Hazards Models, Prospective Studies, Risk Factors, Self Report, Sex Factors, Tea
Show Abstract · Added February 26, 2019
OBJECTIVES - To investigate the association between green tea intake and incident stones in two large prospective cohorts.
METHODS - We examined self-reported incident kidney stone risk in the Shanghai Men's Health Study (n = 58 054; baseline age 40-74 years) and the Shanghai Women's Health Study (n = 69 166; baseline age 40-70 years). Information on the stone history and tea intake was collected by in-person surveys. Multivariable Cox proportional hazards models were adjusted for baseline demographic variables, medical history and dietary intakes including non-tea oxalate from a validated food frequency questionnaire.
RESULTS - During 319 211 and 696 950 person-years of follow up, respectively, 1202 men and 1451 women reported incident stones. Approximately two-thirds of men and one-quarter of women were tea drinkers at baseline, of whom green tea was the primary type consumed (95% in men, 88% in women). Tea drinkers (men: hazard ratio 0.78, 95% confidence interval 0.69-0.88; women: hazard ratio 0.8, 95% confidence interval 0.77-0.98) and specifically green tea drinkers (men: hazard ratio 0.78, 95% confidence interval 0.69-0.88; women: hazard ratio 0.84, 95% confidence interval 0.74-0.95) had lower incident risk than never/former drinkers. Compared with never/former drinkers, a stronger dose-response trend was observed for the amount of dried tea leaf consumed/month by men (hazard ratio 0.67, 95% confidence interval 0.56-0.80, P  < 0.001) than by women (hazard ratio 0.87, 95% confidence interval 0.70-1.08, P  = 0.041).
CONCLUSIONS - Green tea intake is associated with a lower risk of incident kidney stones, and the benefit is observed more strongly among men.

Deficits in Self-Reported Initiation Are AssociatedWith Subsequent Disability in ICU Survivors.
Wilson JE, Duggan MC, Chandrasekhar R, Brummel NE, Dittus RS, Ely EW, Patel MB, Jackson JC
(2019) Psychosomatics 60: 376-384
MeSH Terms: Activities of Daily Living, Aged, Cohort Studies, Critical Illness, Disabled Persons, Executive Function, Female, Humans, Intensive Care Units, Male, Middle Aged, Prospective Studies, Self Report, Survivors
Show Abstract · Added October 28, 2018
OBJECTIVE - To determine whether deficits in a key aspect of executive functioning, namely, initiation, were associated with current and future functional disabilities in intensive care unit survivors.
METHODS - A nested substudy within a 2-center prospective observational cohort. We used 3 tests of initiation at 3 and 12 months: the Ruff Total Unique Design, Controlled Oral Word Association, and Behavior Rating Inventory of Executive Function initiation. Disability in instrumental activities of daily living (IADL) was measured with the Functional Activities Questionnaire. We used a proportional odds logistic regression model to evaluate the association between initiation and disability. Covariates in the model included age, education, baseline Functional Activities Questionnaire, pre-existing cognitive impairment, comorbidities, admission severity of illness, episodes of hypoxia, and days of severe sepsis.
RESULTS - In 195 patients, after adjusting for covariates, only the Behavior Rating Inventory of Executive Function initiation was associated with disability at any time point. Comparing the 25th vs the 75th percentile scores (95% confidence interval) of the Behavior Rating Inventory of Executive Function initiation at 3 months, patients with worse initiation scores had 5.062 times the odds (95% confidence interval: 2.539, 10.092) of disability according to the Functional Activities Questionnaire at 3 months, with similar odds at 12 months (odds ratio: 3.476, 95% confidence interval: 1.943, 6.216). Worse Behavior Rating Inventory of Executive Function initiation scores at 3 months were associated with future disability at 12 months odds ratio (95% confidence interval) 5.079 (2.579, 10.000).
CONCLUSIONS - Executive function deficits acquired after a critical illness in the domain of initiation are common in intensive care unit survivors, and when they are identified via self-report tools, they are associated with current and future disability in instrumental activities of daily living.

Toileting Behaviors of Women-What is Healthy?
Kowalik CG, Daily A, Delpe S, Kaufman MR, Fowke J, Dmochowski RR, Reynolds WS
(2019) J Urol 201: 129-134
MeSH Terms: Adolescent, Adult, Aged, Aged, 80 and over, Female, Health Behavior, Humans, Independent Living, Middle Aged, Self Report, Socioeconomic Factors, Surveys and Questionnaires, Urinary Bladder Diseases, Urination, Young Adult
Show Abstract · Added September 16, 2019
PURPOSE - The objective of this study was to assess toileting behaviors in community dwelling women.
MATERIALS AND METHODS - Women 18 years old or older were recruited through a national registry of research volunteers. They were asked to complete validated questionnaires assessing urinary symptoms and toileting behaviors, specifically place preference for voiding, convenience voiding, delayed voiding, straining during voiding and position preference for voiding. The PPBC (patient perception of bladder condition) was administered to assess the participant impression of bladder health. Analyses were done to determine the prevalence of each toileting behavior reported to occur sometimes or more often as well as differences in toileting behaviors in women with vs without self-perceived bladder problems based on the PPBC response.
RESULTS - The 6,695 women who completed the questionnaires were 18 to 89 years old (mean ± SD age 41.4 ± 15). Of the women 79.9% identified as white and 71.0% were college educated. Of the women 6,613 (98.8%) reported a place preference for voiding. The 3,552 women (53.1%) who reported a bladder problem were more likely to report convenience voiding, delayed voiding and strained voiding behaviors. While 6,657 women (99.4%) reported sitting to void at home only 5,108 (76.2%) reported sitting when using public toilets.
CONCLUSIONS - Certain toileting behaviors, of which some may be considered unhealthy, were common in this sample of women and most were associated with a perception of bladder problems. Voiding positions other than sitting were frequently used when away from home. These data have important implications for defining bladder health and implementing behavior based interventions for women with lower urinary tract symptoms.

Self-reported chemotherapy-related cognitive impairment compared with cognitive complaints following menopause.
Vega JN, Dumas J, Newhouse PA
(2018) Psychooncology 27: 2198-2205
MeSH Terms: Breast Neoplasms, Cancer Survivors, Cognition, Cognitive Dysfunction, Female, Humans, Longitudinal Studies, Menopause, Middle Aged, Quality of Life, Self Report
Show Abstract · Added March 3, 2020
OBJECTIVE - Cancer-related cognitive impairment (CRCI) is commonly reported following the administration of cancer treatment. Current longitudinal studies, primarily in women with breast cancer, suggest that up to 35% to 60% of patients exhibit persistent CRCI (pCRCI) following completion of chemotherapy. Complaints of subjective cognitive decline (SCD) are also commonly reported by women during and following the menopause transition in noncancer patients. Although the majority of evidence for cognitive difficulties in cancer patients and survivors is attributed to chemotherapy, there is growing evidence to suggest that menopausal status can also influence cognitive function in cancer patients.
METHODS - Given that menopausal status may be contributing to pCRCI, we compared a group of primarily postmenopausal women with pCRCI to 2 groups of postmenopausal women: women who endorse menopause-associated SCD (maSCD+) and women who do not (maSCD-) to explore the similarities/differences between maSCD and pCRCI and the potential role of menopause in pCRCI.
RESULTS - Persistent CRCI participants report more severe SCD symptoms than women after natural menopause, despite being on average 2.5-year postchemotherapy, supporting previous findings that CRCI can persist for months to years after completing treatment. Persistent CRCI participants not only endorsed greater SCD but also exhibited objective performance differences. In addition, pCRCI participants endorsed significantly greater menopausal symptoms compared with either maSCD group. Results were not related to menopausal status prior to chemotherapy or current endocrine therapy use.
CONCLUSIONS - These results suggest that while menopausal symptoms may contribute to SCD experienced by cancer patients after chemotherapy, they do not fully account for pCRCI.
