Impact of Population Pharmacogenomics on Cisplatin-Induced Neurotoxicities in Testicular Cancer Survivors.

Background: Cisplatin is a commonly used chemotherapeutic across numerous cancer types that can cause neurotoxicities in patients, including peripheral sensory neuropathy, tinnitus, hearing loss, and vertigo.

Objective: We aimed to evaluate, for the first time, how genetic ancestry impacts cisplatin-induced neurotoxicities and if disparities are related to population differences in allele frequency.

Methods: In a cohort of cisplatin-treated testicular cancer survivors, relationships between genetic ancestry and neurotoxicities, medications, and lifestyle factors were assessed using logistic regression and Kruskal-Wallis tests and multiple pairwise comparisons using the Wilcoxon rank-sum test (Benjamini-Hochberg adjustment).

Factors associated with longitudinal progression of the cumulative burden of morbidity and overall mortality after cisplatin-based chemotherapy for testicular cancer.

Background: To comprehensively evaluate the longitudinal progression of cumulative burden of morbidity (CBM) in testicular cancer survivors (TCS) following standard-dose cisplatin-based chemotherapy and the impact of modifiable risk factors on morbidity and early mortality.

Methods: Participants completed first-line chemotherapy at or longer than 6 months before baseline assessments with comprehensive questionnaires and physical examinations. Based on follow-up assessments (median: 7 years later), longitudinal progression of adverse health outcomes (AHOs) and CBM score (encompassing AHO number and severity) were examined.

Cognitive function in long-term testicular cancer survivors: impact of modifiable factors.

No study has comprehensively examined associated factors (adverse health outcomes, health behaviors, and demographics) affecting cognitive function in long-term testicular cancer survivors (TC survivors). TC survivors given cisplatin-based chemotherapy completed comprehensive, validated surveys, including those that assessed cognition. Medical record abstraction provided cancer and treatment history.

Comprehensive Audiologic Analyses After Cisplatin-Based Chemotherapy.

Importance: Cisplatin is highly ototoxic but widely used. Evidence is lacking regarding cisplatin-related hearing loss (CRHL) in adult-onset cancer survivors with comprehensive audiologic assessments (eg, Words-in-Noise [WIN] tests, full-spectrum audiometry, and additional otologic measures), as well as the progression of CRHL considering comorbidities, modifiable factors associated with risk, and cumulative cisplatin dose.

Objective: To assess CRHL with comprehensive audiologic assessments, including the WIN, evaluate the longitudinal progression of CRHL, and identify factors associated with risk.

Prevalence and risk factors for ototoxicity after cisplatin-based chemotherapy.

Purpose: Ototoxicity is a prominent side effect of cisplatin-based chemotherapy. There are few reports, however, estimating its prevalence in well-defined cohorts and associated risk factors.

Methods: Testicular cancer (TC) survivors given first-line cisplatin-based chemotherapy completed validated questionnaires.

Comprehensive association analysis of speech recognition thresholds after cisplatin-based chemotherapy in survivors of adult-onset cancer.

Purpose: Deficits in speech understanding constitute one of the most severe consequences of hearing loss. Here we investigate the clinical and genetic risk factors for symmetric deterioration of speech recognition thresholds (SRT) among cancer survivors treated with cisplatin.

Methods: SRT was measured using spondaic words and calculating the mean of measurements for both ears with symmetric SRT values.

Associations of Body Fat Distribution and Cardiometabolic Risk of Testicular Cancer Survivors After Cisplatin-Based Chemotherapy.

Background: It is unknown how body fat distribution modulates the cardiometabolic risk of testicular cancer survivors after cisplatin-based chemotherapy.

Methods: For 455 patients enrolled in the Platinum Study at Memorial Sloan Kettering Cancer Center, visceral (VAT) and subcutaneous (SAT) adipose tissue was quantified on prechemotherapy computed tomography. The VAT-to-SAT ratio was calculated as a quantitative measure of central adiposity.

Pharmacogenomics of cisplatin-induced neurotoxicities: Hearing loss, tinnitus, and peripheral sensory neuropathy.

Purpose: Cisplatin is a critical component of first-line chemotherapy for several cancers, but causes peripheral sensory neuropathy, hearing loss, and tinnitus. We aimed to identify comorbidities for cisplatin-induced neurotoxicities among large numbers of similarly treated patients without the confounding effect of cranial radiotherapy.

Methods: Utilizing linear and logistic regression analyses on 1680 well-characterized cisplatin-treated testicular cancer survivors, we analyzed associations of hearing loss, tinnitus, and peripheral neuropathy with nongenetic comorbidities.

Risk Patterns and Mortality in Postmenopausal Women Using Latent Class Analysis.

Introduction: Although risk factors often co-occur, previous studies examining lifestyle or psychosocial factors often treat these factors as individual predictors of health. This study aims to identify the underlying subgroups of women characterized by distinct lifestyle and psychosocial risk patterns and to investigate the prospective associations between risk patterns and mortality among postmenopausal women.

Methods: A total of 64,812 postmenopausal women aged 50-79 years without prevalent diabetes, cardiovascular disease, and cancer at baseline (1993-1998) were followed until 2019 with a mean follow-up duration of 14.

Cisplatin, environmental metals, and cardiovascular disease: an urgent need to understand underlying mechanisms.

Significantly increased risks of cardiovascular disease occur in testicular cancer survivors given cisplatin-based chemotherapy. The postulated mechanism of platinum-based chemotherapy's vascular toxicity has been thought secondary to its different early- and late- effects on vascular injury, endothelial dysfunction, and induction of a hypercoagulable state. We highlight for the first time the similarities between platinum-associated vascular adverse events and the vascular toxicity associated with other xenobiotic-metal contaminants.

Use of Medications for Treating Anxiety or Depression among Testicular Cancer Survivors: A Multi-Institutional Study.

Background: This study examined sociodemographic factors, cisplatin-related adverse health outcomes (AHO), and cumulative burden of morbidity (CBM) scores associated with medication use for anxiety and/or depression in testicular cancer survivors (TCS).

Methods: A total of 1,802 TCS who completed cisplatin-based chemotherapy ≥12 months previously completed questionnaires regarding sociodemographic features and cisplatin-related AHOs [hearing impairment, tinnitus, peripheral sensory neuropathy (PSN), and kidney disease]. A CBM score encompassed the number and severity of cisplatin-related AHOs.

The role of reproductive coercion in women's risk for HIV: A case-control study of outpatients in Gauteng, South Africa.

Objectives: To investigate how reproductive coercion, or men's attempts to control their partners' use of contraception, may contribute to adverse reproductive health outcomes for women including abortions, sexually transmitted infections, and HIV for young women in South Africa.

Methods: Findings are based on a case-control interview study of 882 South African women outpatients aged 15-29 years, 48.5% (n=427) of whom were HIV seropositive.

Associations of adiponectin and leptin with brain natriuretic peptide in African Americans: the Jackson Heart Study.

Unlabelled: Brain natriuretic peptide (BNP) is elevated in decompensated systolic and diastolic heart failure. The plasma levels of adipokines, such as adiponectin and leptin, may provide evidence for mechanistic differences in BNP concentrations. African-American-specific associations are limited in the literature.

Solid and Hematologic Neoplasms After Testicular Cancer: A US Population-Based Study of 24 900 Survivors.

Background: No large US population-based study focusing on recent decades, to our knowledge, has comprehensively examined risks of second malignant solid and hematological neoplasms (solid-SMN and heme-SMN) after testicular cancer (TC), taking into account initial therapy and histological type.

Methods: Standardized incidence ratios (SIR) vs the general population and 95% confidence intervals (CI) for solid-SMN and heme-SMN were calculated for 24 900 TC survivors (TCS) reported to the National Cancer Institute's Surveillance, Epidemiology, and End Results registries (1973-2014). All statistical tests were two-sided.

Lifestyle and Psychosocial Patterns and Diabetes Incidence Among Women with and Without Obesity: a Prospective Latent Class Analysis.

We conducted latent class analyses to identify women with homogeneous combinations of lifestyle and behavioral variables and tested whether latent classes were prospectively associated with diabetes incidence for women with or without baseline obesity. A total of 64,710 postmenopausal women aged 50-79 years without prevalent diabetes at baseline (years 1993-1998) were followed until 2018 with a mean follow-up of 14.6 years (sd = 6.

Adverse Health Outcomes Among US Testicular Cancer Survivors After Cisplatin-Based Chemotherapy vs Surgical Management.

We evaluated for the first time, to our knowledge, adverse health outcomes (AHOs) among US testicular cancer survivors (TCS) given chemotherapy (n = 381) vs surgery-only patients (n = 98) managed at a single institution, accounting for non-treatment-related risk factors to delineate chemotherapy's impact. Chemotherapy consisted largely of bleomycin-etoposide-cisplatin (BEP) administered in three or four cycles (BEPx3, n = 235; BEPx4, n = 82). Incidence of at least 3 AHOs was lowest in surgery-only TCS and increased with BEPx3, BEPx4, and other cisplatin-based regimens (12.

Associations of leptin and adiponectin with incident type 2 diabetes and interactions among African Americans: the Jackson heart study.

Background: Growing evidence suggests that leptin is critical for glycemic control. Impaired leptin signaling may also contribute to low adiponectin expression in obese individuals. We assessed the association of leptin and adiponectin with incident type 2 diabetes (T2D), their interactions with sex and obesity status, and mediation by insulin resistance.

The association between sleep duration and lipid profiles: the NHANES 2013-2014.

Background: In the current literature, the association between sleep and different lipids is inconsistent. We aimed to assess the association of sleep with HDL cholesterol, triglyceride, and LDL cholesterol in the National Health and Nutrition Examination Survey (NHANES), 2013/2014.

Methods: We included 2705 participants from NHANES, 2013/2014.

Testicular Cancer Survivorship.

Testicular cancer (TC) is the most common cancer among men aged 18 to 39 years. It is highly curable, with a 10-year relative survival approaching 95% due to effective cisplatin-based chemotherapy. Given the increasing incidence of TC and improved survival, TC survivors (TCS) now account for approximately 4% of all US male cancer survivors.
