A Cross-Sectional Analysis of Testicular Cancer Symptom Recognition and Stage of Diagnosis.

There is a need to further explore the relationship between atypical symptom reporting and stage diagnosis to help develop a clearer defined list of possible testicular cancer (TC) symptoms that could assist physicians diagnose the disease earlier. A cross-sectional study was employed to explore possible associations between TC symptom presentation and stage of diagnosis. An original 40-item survey was distributed among 698 TC survivors to determine the potential impact of several risk factors, experiences, and behaviors upon diagnosis. This analysis aimed to explore how certain patient-driven experiences (e.g., symptoms, perceptions, and behaviors) could serve as catalysts for seeking medical care for testicular health concerns. Experiencing hot flashes or having no symptoms had a positive association with later-stage diagnosis while change in shape had a significant negative association with later-stage diagnosis. While the logistic regression model explained relatively low variance in the data (R2 = .1415), it was statistically significant (χ2p < .001). Pain (odds ratio [OR] = 1.6524, p < .05), hot flashes (OR = 5.7893, p < .01), and no symptoms experienced (OR = 12.4836, p < .01) were all significant predictors of a more advanced stage diagnosis. The concern around uncommon/atypical symptoms are that they are indistinct and do not serve as clear signs that TC is present. However, perhaps in tandem with other more overt symptoms, their discovery can serve in a more confirmatory role for a suspect case. If observed with other uncommonly reported symptoms, these uncommon symptoms could provide another pathway in the TC diagnostic process. Clinical and patient education is warranted to increase awareness of uncommon TC symptoms.

The Association Between Testicular Self-Examination and Stages of Testicular Cancer Diagnosis: A Cross-Sectional Analysis.

Purpose: Testicular cancer (TC) is the most prevalent tumor diagnosed in men 15-40 years of age. Survivorship and quality of life dramatically decrease with late-stage diagnosis. Testicular self-examination (TSE) is a diagnostic method used to discover early-stage tumor incidence. This study examines the relationship between practicing TSE and stage of diagnosis for TC survivors. Methods: A cross-sectional study design was employed, a 40-item survey among TC survivors (n = 619). Bivariate analyses consisted of Spearman Rho correlations of all primary variables with stage diagnosis of TC. Multivariate analysis employed an ordered logistic regression to determine stage diagnosis predictors. Results: "Regular" TSE practice significantly related with awareness (r = 0.4533) and knowledge of (r = 0.4866) TSE, confidence performing TSE (r = 0.4961), and feeling shape/feel differences of the testicle before diagnosis (r = 0.2115). Factors that had a statistically significant negative association with later-stage diagnosis included awareness (r = -0.1180) and knowledge of (r = -0.1586) TSE, confidence performing TSE (r = -0.1138), and feeling shape/feel differences of the testicle before diagnosis (r = -0.2938), among others. Regular TSE practice significantly predicted decreased odds of later-stage diagnosis within the sample subset reporting delay (odds ratio = 0.1628; p < 0.05); however, there was no significant relationship between regular TSE practice and stage diagnosis within the other model variations. Conclusion: This exploratory analysis aimed to provide baseline evidence of the possible association between the practice of TSE and the stage of TC diagnosis, and therefore making an indirect claim that TSE has the potential to improve quality of life and decrease TC mortality, particularly among adolescents and young adults.

Testicular Cancer Incidence and Mortality Within Rural and Urban Regions.

Purpose: Testicular cancer (TCa) is among the most common cancers within adolescent and young adult (AYA) male populations. However, information is limited to variations in incidence and mortality outside of racial/ethnic subgroups. Rural regions historically have a greater overall cancer incidence than urban regions, although some key differences exist regarding site. TCa-specific incidence and mortality disparities are not commonly reported in this context. This study aims to help fill that gap by providing discovery evidence if there is an association between US rural/urban regions and TCa incidence and mortality. Methods: Secondary analysis of Surveillance, Epidemiology, and End Results incidence and mortality data were employed to determine if rural/urban TCa incidence and mortality disparities exist among U.S. males. Results: There was a 2.6% increased rate of TCa in U.S. urban as compared with rural geographic regions from 2011 to 2015. When geographic region is disaggregated, rural regions see higher rates than urban. When factoring in race/ethnicity, White/Caucasians and Hispanics had statistically higher urban rates whereas American Indian/Alaskan Natives and Asian/Pacific Islander groups had statistically higher rural rates. Conclusion: Geographic regional TCa variation research is virtually nonexistent for U.S. males, specifically AYAs of color. Determining preliminary trends in rural and urban regions can assist in the creation of more targeted services, particularly among underserved and vulnerable populations that have tenuous access to health care, to reduce disparate health outcomes. Exploring geographic differences in TCa incidence and mortality can have implications within service industry, health care accessibility, and public health justice areas of research and outreach.

The Connection Between Testicular Cancer, Minority Males, and Planned Parenthood.

Testicular cancer (TCa) is the most prevalent neoplasm diagnosed in males aged 15-40 years. Lack of access to care is a key impediment to early-stage TCa diagnosis. Health equity concerns arise, however, as poor access largely manifests within underserved male populations, therefore, placing them at a higher risk to develop late-stage TCa. Planned Parenthood Federation of America (PPFA) offers a myriad of male reproductive/sexual health care options, including TCa screening and referral services. Therefore, expanding these amenities in traditionally underserved communities may address the concern of TCa screening opportunities. An ecological analysis was performed using data from the United States Cancer Statistics, American Community Survey, and PPFA databases to assess the impact of TCa upon minority males, identify associations between PPFA services and minority males, and provide future implications on the role PPFA may play in bridging health-care access gaps pertaining to TCa screenings. Results indicate that states with higher rates of poverty and uninsured individuals, as well as specifically Black/African American males, have lower TCa incidence and limited access to screening services. PPFA service presence and Black/African American, as well as uninsured, males had a negative association but revealed positive correlations with TCa incidence. Considering the emerging TCa outcome disparities among minority males, expanding PPFA men's health services is crucial in providing affordable options to help identify testicular abnormalities that are early stage or carcinoma in situ. Many at-risk males have limited means to obtain TCa screening services. Expanding this discussion could provide a foundation for future advocacy.

USPSTF Testicular Examination Nomination-Self-Examinations and Examinations in a Clinical Setting.

In 2004, the U.S. Preventive Services Task Force (USPSTF) published a Grade D recommendation for both testicular self-examination (TSE) and clinical evaluation to screen for testicular cancer in asymptomatic males. This review committee reaffirmed these recommendations in 2009 and again in 2011 (Testicular Cancer: Screening Release Date: April 2011. Final Update Summary: Testicular Cancer: Screening. U.S. Preventive Services Task Force. September 2016). The 2011 USPSTF review found no significant evidence that would warrant a change from the last full review in 2004. We believe that the USPSTF erred in its assessments. As acknowledged in the task force report, testicular cancer is not believed to be preventable, and treatment of early detected testicular cancer is generally associated with very favorable outcomes; it is our belief therefore that every encouragement should be given to early detection. We are therefore requesting that the USPSTF review the D rating for testicular examination, both in a clinical setting and as self-examination. We are requesting this, as recent studies and public health warrant a change in grade. The new studies build on earlier studies that support the benefits of regular screening by individuals and their physicians. Further, and equally important, we believe that the current grade and attendant information confuses men and boys about the importance of self-care and wellness and continues to inadvertently reinforce negative cultural attitudes. We believe that adjusting the rating to a Grade B is both warranted and necessary.

The strong correlation between neonatal early-onset Group B Streptococcal disease and necrotizing enterocolitis.

BACKGROUND: Necrotizing enterocolitis (NEC) is a leading cause of newborn gastrointestinal emergencies, affecting 1-3 per 1000 live births. Although NEC has been linked to a microbial etiology, associations with maternal intrapartum and resultant newborn early-onset invasive Group B streptococcus (EO-GBS) have been weakly defined. OBJECTIVE: The study aim was to determine the relationship between EO-GBS and NEC. STUDY DESIGN: Data from 2008 to 2015 were collected from pediatric records with ICD diagnosis codes consistent with all stages of NEC, with the exception of neonatal EO-GBS data (only available 2011-2015). RESULTS: For the 131 newborns meeting inclusion criteria, the mean gestational age (GA) and birthweight at delivery was 30.2 weeks and 1449 g. Maternal comorbidities were not associated with a more advanced stage of NEC, however male gender (OR 3.2, p < .001), lower mean 1 (OR = 0.89, p = .045) and 5 min Apgar scores (OR = 0.84, p = .009) were significantly associated with higher NEC stage, after controlling for GA. Infectious morbidities including chorioamnionitis (OR = 1.5, p = .553) and intrapartum antibiotic administration (OR = 1.3, p = .524) were not significantly associated with higher NEC stage. Neither neonatal sepsis workup (OR = 0.27, p = .060) nor positive blood culture (OR = 0.97, p = .942) prior to NEC diagnosis were statistically significant. Type of feed prior to diagnosis (p = .530) was not significantly associated with NEC stage, however, expressed breast milk tended to be protective against higher stage of NEC (OR = 0.49, p = .055). Type of feed included total parenteral nutrition, mother's or donor expressed breast milk, trophic, full and high calorie feeds. Of the 579 newborns admitted from 2011 to 2015, 13 (2%) were diagnosed with EO-GBS and 64 met diagnostic criteria for NEC. GBS positive newborns had significantly higher odds of NEC (OR = 5.37, p = .009). NEC stage was not significantly different for patients with GBS positive vs. GBS negative mothers (p = .732), nor was there a significant difference in GA (p = .161). CONCLUSION: Our study is the first to describe a strong correlation between neonatal EO- GBS disease and NEC, with more than a five-fold increase in the odds of developing NEC in newborns of GBS positive mothers. PURPOSE: To investigate a possible relationship between EO-GBS disease and the neonatal diagnosis of NEC. Secondary analysis will determine if maternal antepartum and intrapartum factors along with neonatal variables contribute to a more advanced stage of NEC by retrospective chart review of patient data collected at Children's Hospital: New Orleans.

Phacodynamics: an aspiration flow vs vacuum comparison.

PURPOSE: To compare actual flow and the vacuum necessary to generate that flow for the Advanced Medical Optics Sovereign (Advanced Medical Optics, Santa Ana, California, USA) and the Alcon Legacy (Alcon, Fort Worth, Texas, USA) phacoemulsification machines. DESIGN: In vitro laboratory study. METHODS: Flow was collected and machine indicated vacuum noted from 12 ml/min to 40 ml/min in 2 ml/min steps (20-gauge). Nineteen and 20-gauge tips were also compared. Machine indicated vacuum was converted to actual tip vacuum. RESULTS: Legacy flow (102.4 +/- 3.8% of indicated) was significantly more than Sovereign (96.5 +/- 3.9%; P < .0001). 20-gauge flow was less than 19-gauge flow (96.1% vs 98.6% of indicated, P < .0001). Sovereign had less unoccluded vacuum (70.3 +/- 3.2 mm Hg) than Legacy (89.4 +/- 1.2 mm Hg) at 36 ml/min of flow (P < .0001 for 26 to 36 ml/min of flow). CONCLUSION: There is unoccluded vacuum at the phaco tip of these systems at 14 ml/min, of flow and at 40 ml/min, this was 112.0 mm Hg for the Legacy.

The evaluation of light sensitivity in benign essential blepharospasm.

PURPOSE: To test light sensitivity thresholds rigorously in patients with benign essential blepharospasm (BEB) compared with patients who have known light sensitivity (migraineurs) and to normal control subjects. DESIGN: Prospective, observational, case control study. METHODS: We recruited a total of 87 subjects into each of three groups: BEB, migraine, and normal control subjects. A modified slit-lamp chin rest, heat shield, light meter, and halogen light that was modulated by a rheostat were used to measure light sensitivity thresholds. Participants were tested without spectacles, with gray-tinted spectacles, and with FL-41-tinted spectacles. RESULTS: Light discomfort thresholds for subjects with BEB were significantly lower compared with normal control subjects (P < or = .009) and similar to the migraine group. Both gray and FL-41-tinted lenses improved light sensitivity thresholds in all groups (P < or = .0005). There was no observed difference in the improvement in light sensitivity when the gray and FL-41-tinted lenses were compared. CONCLUSION: Patients with BEB are considerably more sensitive to light than control subjects and as sensitive to light as patients with migraine. Physicians who care for patients with BEB should consider using tinted lenses to help ameliorate symptoms.

Comparison of thermal features associated with 2 phacoemulsification machines.

PURPOSE: To determine the thermal characteristics of the Legacy Advantec and Sovereign WhiteStar phacoemulsification machines during different clinically relevant scenarios. SETTING: In vitro study. METHODS: In water, temperature was recorded continuously on the sleeve in an artificial chamber, and the increase in temperature over baseline after 60 seconds of ultrasound was determined. This was done for continuous ultrasound, 50 ms on and 50 ms off (pulse), 6 ms on and 12 ms off (WhiteStar; Sovereign only) with aspiration blocked and not blocked, and with 100 g and 200 g weights suspended from the sleeve. RESULTS: Comparing temperature increase per 20% machine power increments, Sovereign ran hotter than Legacy Advantec for continuous ultrasound (2.31x) and pulse (2.23x). Blocking aspiration increased temperature over the unblocked state. Pulsing decreased temperature by 51% (Legacy Advantec, pulse), 52% (Sovereign, pulse), and 64% (WhiteStar). Weights had much more effect on the Legacy Advantec: 3.5 times more going from baseline to 100 g weights and 3.2 times more going from 100 to 200 g weights. For all these comparisons, the P value was less than 0.0001. CONCLUSIONS: The machines behaved fundamentally differently, with the Legacy Advantec controlling stroke length and Sovereign controlling a fixed power at any setting. Therefore, workload had a much bigger impact on Legacy Advantec thermal characteristics. Pulsing decreased heat produced directly related to the duty cycle. The most dangerous incision burn scenario is with continuous ultrasound, aspiration blocked, and a heavy workload.
