Early Interventional Treatment of High Output Chyle Leak After Esophagectomy is Associated With Improved Survival.

OBJECTIVE: To investigate overall survival and length of stay (LOS) associated with differing management for high output (>1 L over 24 hours) leaks (HOCL) after cancer-related esophagectomy. BACKGROUND: Although infrequent, chyle leak after esophagectomy is an event that can lead to significant perioperative sequelae. Low-volume leaks appear to respond to nonoperative measures, whereas HOCLs often require invasive therapeutic interventions. METHODS: From a prospective single-institution database, we retrospectively reviewed patients treated from 2001 to 2021 who underwent esophagectomy for esophageal cancer. Within that cohort, we focused on a subgroup of patients who manifested a HOCL postoperatively. Clinicopathologic and operative characteristics were collected, including hospital LOS and survival data. RESULTS: A total of 53/2299 patients manifested a HOCL. These were mostly males (77%), with a mean age of 62 years. Of this group, 15 patients received nonoperative management, 15 patients received prompt (<72 hours from diagnosis) interventional management, and 23 received late interventional management. Patients in the late intervention group had longer LOSs compared with early intervention (slope = 9.849, 95% CI: 3.431-16.267). Late intervention (hazard ratio: 4.772, CI: 1.384-16.460) and nonoperative management (hazard ratio: 4.731, CI: 1.294-17.305) were associated with increased mortality compared with early intervention. Patients with early intervention for HOCL had an overall survival similar to patients without chyle leaks in survival analysis. CONCLUSIONS: Patients with HOCL should receive early intervention to possibly reverse the prognostic implications of this potentially detrimental complication.

Factors associated with dating app use for sexual "hookups" in the United States: insights from the National Survey of Family Growth.

BACKGROUND: The use of dating applications for matchmaking and sexual exploits ("hookups") has increased, and this modern phenomenon has supplanted traditional socialization and relationship formation. To date, sociodemographic data on the use of dating apps has been limited. AIM: In this study, we sought to identify predictors associated with the use of dating apps in the United States. METHODS: Using cross-sectional data from the 2017-2019 National Survey of Family Growth, we examined sociodemographic determinants influencing the use of dating apps to find partners for sexual intercourse. We constructed survey-weighted regression models to study these associations, with additional sensitivity analyses performed within specific subgroups. Furthermore, this study investigated the correlation of app use with sexual frequency. OUTCOME: Study outcomes were participant data regarding reported use of dating apps for sexual intercourse in the 2017-2019 National Survey of Family Growth. RESULTS: A total of 11,225 respondents were examined, representing a survey-weighted total of approximately 143,201, 286 Americans. Among them, 757 respondents (6.7%), equating to approximately 8, 818, 743 individuals, reported dating app use for sexual hookups. Regression analysis revealed that factors such as male sex, White race, previous sexual experience, substance/alcohol use, history of sexually transmitted infections, same-sex attraction, and bisexuality increased the likelihood of dating app usage. Conversely, reduced odds of dating app use were observed among Catholics, Protestants, married/widowed individuals, and older respondents. Stratified analyses across various demographics, including male and female individuals aged 20 to 40 years, heterosexual, and lesbian, gay, and bisexual respondents, generally supported these trends. Notably, dating app use did not correlate with increased sexual frequency (adjusted incidence rate ratio: 1.10; 95% CI: 0.96-1.26; P = .16). CLINICAL IMPLICATIONS: Dating app use is prevalent among male patients and White individuals and correlates with increased sexually transmitted infection risk, alcohol/illicit substance use, past sexual experience, and popularity within the lesbian, gay, and bisexual community, all important considerations for public health interventions. Dating app use, however, was not associated with increased sexual encounters. STRENGTHS AND LIMITATIONS: Strengths of our study were the utilization of a national survey of individuals of reproductive age in the United States and focus on a clearly defined outcome of dating app utilization for the purposes of sexual intercourse. Limitations include self-reported survey responses and insufficient detail on the types and duration of dating app platforms and their use. CONCLUSIONS: Many sociodemographic factors, including male sex, White race, history of STIs, substance and alcohol use, and same-sex and bisexual attraction, were linked with dating app use. However, there was no increase in sexual frequency associated with dating app utilization. Further research is essential for integrating these technologies into the relational and sexual dynamics of individuals.

Relationship of Surgical Approach With Financial Toxicity in Patients With Resected Lung Cancer.

INTRODUCTION: Minimally invasive surgery (MIS) reduces lengths of stay, complications, and potentially perioperative hospital costs. However, the impact of MIS on financial toxicity (FT), defined as the costs resulting from oncologic care and their negative effects on quality of life, in patients with lung cancer is unknown. Our objective was to investigate the association between surgical approach and FT in this population. METHODS: A single-institution study was performed evaluating resected lung cancer patients (2016-2021). FT was assessed using the Comprehensive Score for Financial Toxicity (COST) questionnaire. The relationship between surgical approach (MIS vs. thoracotomy) and FT was evaluated using propensity score-matched (PSM) regression analysis. A sensitivity analysis involving the entire cohort was also performed using an inverse probability-weighted generalized linear model. RESULTS: As reported previously, of 1477 patients surveyed, 463 responded (31.3%) with FT reported in 196 patients (42.3%). Resection was performed by thoracotomy in 53.3% (n = 247), and by MIS in the remainder (n = 216, 46.7%; video-assisted thoracoscopic surgery [VATS] = 115; robotic-assisted = 101). There was no difference in FT in patients who underwent VATS and robotic-assisted surgery (p = 0.515). In the PSM analysis, MIS was not associated with FT (odds ratio [OR]: 0.980, 95% confidence interval [CI]: 0.628-1.533, p = 0.929). Similar results were found on sensitivity analysis (OR: 1.488, CI: 0.931-2.378, p = 0.096). CONCLUSIONS: Compared to MIS, thoracotomy was not associated with FT in patients with resected lung cancer. Though there are several benefits from MIS, it does not appear to be a meaningful strategy to alleviate FT in this population.

Do resected colorectal cancer patients need early chest imaging? Impact of clinicopathologic characteristics on time to development of pulmonary metastases.

BACKGROUND AND OBJECTIVES: For patients with colorectal cancer (CRC), the lung is the most common extra-abdominal site of distant metastasis. However, practices for chest imaging after colorectal resection vary widely. We aimed to identify characteristics that may indicate a need for early follow-up imaging. METHODS: We retrospectively reviewed charts of patients who underwent CRC resection, collecting clinicopathologic details and oncologic outcomes. Patients were grouped by timing of pulmonary metastases (PM) development. Analyses were performed to investigate odds ratio (OR) of PM diagnosis within 3 months of CRC resection. RESULTS: Of 1600 patients with resected CRC, 233 (14.6%) developed PM, at a median of 15.4 months following CRC resection. Univariable analyses revealed age, receipt of systemic therapy, lymph node ratio (LNR), lymphovascular and perineural invasion, and KRAS mutation as risk factors for PM. Furthermore, multivariable regression showed neoadjuvant therapy (OR: 2.99, p < 0.001), adjuvant therapy (OR: 6.28, p < 0.001), LNR (OR: 28.91, p < 0.001), and KRAS alteration (OR: 5.19, p < 0.001) to predict PM within 3 months post-resection. CONCLUSIONS: We identified clinicopathologic characteristics that predict development of PM within 3 months after primary CRC resection. Early surveillance in such patients should be emphasized to ensure timely identification and treatment of PM.

Octreotide's role in the management of post-esophagectomy chylothorax.

The use of octreotide in managing intrathoracic chyle leak following esophagectomy has gained popularity in the adult population. While the benefits of octreotide have been confirmed in the pediatric population, there remains limited evidence to support its use in the adults post-esophagectomy. Thus, we performed a single-institution cohort study to characterize its efficacy. The study was performed using a prospective, single-center database, from which clinicopathologic characteristics were extracted of patients who had post-esophagectomy chyle leaks. Kaplan-Meier and multivariable Cox regression analyses were performed to investigate the effect of octreotide use on chest tube duration (CTD), hospital length of stay (LOS), and overall survival (OS). In our cohort, 74 patients met inclusion criteria, among whom 27 (36.5%) received octreotide. Kaplan-Meier revealed no significant effect of octreotide on CTD (P = 0.890), LOS (P = 0.740), or OS (P = 0.570). Multivariable Cox regression analyses further corroborated that octreotide had no effect on CTD (HR = 0.62, 95% confidence interval [CI]: 0.32-1.20, P = 0.155), LOS (HR = 0.64, CI: 0.34-1.21, P = 0.168), or OS (1.08, CI: 0.53-2.19, P = 0.833). Octreotide use in adult patients with chyle leak following esophagectomy lacks evidence of association with meaningful clinical outcomes. Level 1 evidence is needed prior to further consideration in this population.

Male Reproductive Disorders and Fertility Trends: Influences of Environment and Genetic Susceptibility.

It is predicted that Japan and European Union will soon experience appreciable decreases in their populations due to persistently low total fertility rates (TFR) below replacement level (2.1 child per woman). In the United States, where TFR has also declined, there are ethnic differences. Caucasians have rates below replacement, while TFRs among African-Americans and Hispanics are higher. We review possible links between TFR and trends in a range of male reproductive problems, including testicular cancer, disorders of sex development, cryptorchidism, hypospadias, low testosterone levels, poor semen quality, childlessness, changed sex ratio, and increasing demand for assisted reproductive techniques. We present evidence that several adult male reproductive problems arise in utero and are signs of testicular dysgenesis syndrome (TDS). Although TDS might result from genetic mutations, recent evidence suggests that it most often is related to environmental exposures of the fetal testis. However, environmental factors can also affect the adult endocrine system. Based on our review of genetic and environmental factors, we conclude that environmental exposures arising from modern lifestyle, rather than genetics, are the most important factors in the observed trends. These environmental factors might act either directly or via epigenetic mechanisms. In the latter case, the effects of exposures might have an impact for several generations post-exposure. In conclusion, there is an urgent need to prioritize research in reproductive physiology and pathophysiology, particularly in highly industrialized countries facing decreasing populations. We highlight a number of topics that need attention by researchers in human physiology, pathophysiology, environmental health sciences, and demography.

Financial Toxicity in Patients With Resected Lung Cancer.

OBJECTIVES: To describe financial toxicity (FT) in patients with resected lung cancer and identify risk factors in this population. BACKGROUND: FT describes the financial burden associated with cancer care and its impact on the quality of survivorship. Few prior studies have examined FT in patients with lung cancer. METHODS: Patients who underwent lung cancer resection at our institution between January 1, 2016 and December 31, 2021, were surveyed to gather demographic information and evaluate FT using a validated questionnaire. A multivariable model was built to identify risk factors for FT. RESULTS: Of the total, 1477 patients were contacted, of whom 463 responded (31.3%). Most patients were stage I (n = 349, 75.4%) and lobectomy was performed often (n = 290, 62.8%). There were 196 patients (42.3%) who experienced FT. Upon multivariable analyses, divorced marital status [odds ratio (OR) = 3.658, 95% CI: 1.180-11.337], household income <$40,000 (OR = 2.544, 95% CI: 1.003-6.455), credit score below 739 (OR = 2.744, 95% CI: 1.326-5.679), clinical stage >I (OR = 2.053, 95% CI: 1.088-3.877), and change in work hours or work cessation (all P < 0.05) were associated with FT. Coping mechanisms, such as decreased spending on food or clothing and increased use of savings or borrowing money, were more likely to be reported by patients experiencing FT than those who did not ( P < 0.001). CONCLUSIONS: Patients undergoing lung cancer resection often experienced significant financial stress with several identifiable risk factors. FT should be considered early in the care of these patients to alleviate detrimental coping mechanisms and enhance their quality of survivorship.

Paternal Medications in Inflammatory Bowel Disease and Male Fertility and Reproductive Outcomes: A Systematic Review and Meta-analysis.

BACKGROUND & AIMS: Studies evaluating reproductive outcomes among male patients with inflammatory bowel disease (IBD) are limited. We evaluated use of IBD medications and association with semen parameters, a proxy of male fertility, and adverse pregnancy outcomes (early pregnancy loss [EPL], preterm birth [PB], congenital malformations [CM]). METHODS: We searched Medline, Embase, Scopus, and Web of Science (PROSPERO CRD42020197098) from inception to April 2022 for studies reporting semen parameters and adverse pregnancy outcomes among male patients exposed to biologics, thiopurine, or methotrexate. Standardized mean difference, prevalence, and odds ratios (ORs) of outcomes were pooled and analyzed using a random effects model. RESULTS: Ten studies reporting semen parameters (268 patients with IBD) and 16 studies reporting adverse pregnancy outcomes (over 25,000 patients with IBD) were included. Biologic, thiopurine, or methotrexate use were not associated with decreased sperm count, motility, or abnormal morphology compared with nonexposed patients. The prevalence of adverse pregnancy outcomes with paternal biologic (5%), thiopurine (6%), or methotrexate (6%) exposure was comparable to nonexposed patients (5%). Biologic use was not associated with risk of EPL (OR, 1.26; I2 = 0%; P = .12), PB (OR, 1.10; I2 = 0%; P = .17), or CM (OR, 1.03; I2 = 0%; P = .69). Thiopurine use was not associated with risk of EPL (OR, 1.31; I2 = 19%; P = .17), PB (OR, 1.05; I2 = 0%; P = .20), or CM (OR, 1.07; I2 = 7%; P = .34). Methotrexate use was not associated with risk of PB (OR, 1.06; I2 = 0%; P = .62) or CM (OR, 1.03; I2 = 0%; P = .81). CONCLUSIONS: Biologic, thiopurine, or methotrexate use among male patients with IBD are not associated with impairments in fertility or with increased odds of adverse pregnancy outcomes.

The Risk of Cardiovascular and Cerebrovascular Disease in Men With a History of Priapism.

PURPOSE: Priapism is a debilitating condition that affects sexual function. As a majority of cases are idiopathic, investigators have hypothesized underlying vascular dysfunction which may predispose men to priapism. We sought to determine if men are at risk for other sequelae of vascular dysfunction such as cardiovascular and thromboembolic disease after a priapism event. MATERIALS AND METHODS: Using a large commercial insurance claims data warehouse, we evaluated all men (age ≥20) with a diagnosis of priapism from 2003-2020 and matched them to a cohort of men with other urological disorders of sexual dysfunction (erectile dysfunction, Peyronie's disease, and premature ejaculation). We identified incident disease (cardiovascular disease, heart disease, embolism, thrombosis, cerebrovascular disease) for all cohorts. RESULTS: A total of 10,459 men with priapism were identified and were matched to men with erectile dysfunction, Peyronie's disease, or premature ejaculation. The mean age was 51.1 years old. Men with priapism showed increased incidence of heart disease, both ischemic (HR 1.24, 95% CI 1.09-1.42) and other heart disease (HR 1.24, 95% CI 1.12-1.38) in the years following the priapism diagnosis. Incident cerebrovascular disease was also more likely in men with a history of priapism (HR 1.33, 95% CI 1.15-1.55). Men requiring treatment for ischemic priapism had a higher hazard of cardiovascular and cerebrovascular disease. In addition, men with more priapism episodes had a higher rate of cardiovascular disease and thromboembolic events. CONCLUSIONS: Men with priapism are at increased risk for cardiovascular and cerebrovascular events in the years following a priapism.

Association of male fatty acid intake with fecundability among couples planning pregnancy.

STUDY QUESTION: To what extent is male fatty acid intake associated with fecundability among couples planning pregnancy? SUMMARY ANSWER: We observed weak positive associations of male dietary intakes of total and saturated fatty acids with fecundability; no other fatty acid subtypes were appreciably associated with fecundability. WHAT IS KNOWN ALREADY: Male fatty acid intake has been associated with semen quality in previous studies. However, little is known about the extent to which male fatty acid intake is associated with fecundability among couples attempting spontaneous conception. STUDY DESIGN, SIZE, DURATION: We conducted an internet-based preconception prospective cohort study of 697 couples who enrolled during 2015-2022. During 12 cycles of observation, 53 couples (7.6%) were lost to follow-up. PARTICIPANTS/MATERIALS, SETTING, METHODS: Participants were residents of the USA or Canada, aged 21-45 years, and not using fertility treatment at enrollment. At baseline, male participants completed a food frequency questionnaire from which we estimated intakes of total fat and fatty acid subtypes. We ascertained time to pregnancy using questionnaires completed every 8 weeks by female participants until conception or up to 12 months. We used proportional probabilities regression models to estimate fecundability ratios (FRs) and 95% CIs for the associations of fat intakes with fecundability, adjusting for male and female partner characteristics. We used the multivariate nutrient density method to account for energy intake, allowing for interpretation of results as fat intake replacing carbohydrate intake. We conducted several sensitivity analyses to assess the potential for confounding, selection bias, and reverse causation. MAIN RESULTS AND THE ROLE OF CHANCE: Among 697 couples, we observed 465 pregnancies during 2970 menstrual cycles of follow-up. The cumulative incidence of pregnancy during 12 cycles of follow-up after accounting for censoring was 76%. Intakes of total and saturated fatty acids were weakly, positively associated with fecundability. Fully adjusted FRs for quartiles of total fat intake were 1.32 (95% CI 1.01-1.71), 1.16 (95% CI 0.88-1.51), and 1.43 (95% CI 1.09-1.88) for the second, third, and fourth vs the first quartile, respectively. Fully adjusted FRs for saturated fatty acid intake were 1.21 (95% CI 0.94-1.55), 1.16 (95% CI 0.89-1.51), and 1.23 (95% CI 0.94-1.62) for the second, third, and fourth vs the first quartile, respectively. Intakes of monounsaturated, polyunsaturated, trans-, omega-3, and omega-6 fatty acids were not strongly associated with fecundability. Results were similar after adjustment for the female partner's intakes of trans- and omega-3 fats. LIMITATIONS, REASONS FOR CAUTION: Dietary intakes estimated from the food frequency questionnaire may be subject to non-differential misclassification, which is expected to bias results toward the null in the extreme categories when exposures are modeled as quartiles. There may be residual confounding by unmeasured dietary, lifestyle, or environmental factors. Sample size was limited, especially in subgroup analyses. WIDER IMPLICATIONS OF THE FINDINGS: Our results do not support a strong causal effect of male fatty acid intakes on fecundability among couples attempting to conceive spontaneously. The weak positive associations we observed between male dietary fat intakes and fecundability may reflect a combination of causal associations, measurement error, chance, and residual confounding.

A prospective cohort study of preconception COVID-19 vaccination and miscarriage.

STUDY QUESTION: To what extent is preconception maternal or paternal coronavirus disease 2019 (COVID-19) vaccination associated with miscarriage incidence? SUMMARY ANSWER: COVID-19 vaccination in either partner at any time before conception is not associated with an increased rate of miscarriage. WHAT IS KNOWN ALREADY: Several observational studies have evaluated the safety of COVID-19 vaccination during pregnancy and found no association with miscarriage, though no study prospectively evaluated the risk of early miscarriage (gestational weeks [GW] <8) in relation to COVID-19 vaccination. Moreover, no study has evaluated the role of preconception vaccination in both male and female partners. STUDY DESIGN, SIZE, DURATION: An Internet-based, prospective preconception cohort study of couples residing in the USA and Canada. We analyzed data from 1815 female participants who conceived during December 2020-November 2022, including 1570 couples with data on male partner vaccination. PARTICIPANTS/MATERIALS, SETTING, METHODS: Eligible female participants were aged 21-45 years and were trying to conceive without use of fertility treatment at enrollment. Female participants completed questionnaires at baseline, every 8 weeks until pregnancy, and during early and late pregnancy; they could also invite their male partners to complete a baseline questionnaire. We collected data on COVID-19 vaccination (brand and date of doses), history of SARS-CoV-2 infection (yes/no and date of positive test), potential confounders (demographic, reproductive, and lifestyle characteristics), and pregnancy status on all questionnaires. Vaccination status was categorized as never (0 doses before conception), ever (≥1 dose before conception), having a full primary sequence before conception, and completing the full primary sequence ≤3 months before conception. These categories were not mutually exclusive. Participants were followed up from their first positive pregnancy test until miscarriage or a censoring event (induced abortion, ectopic pregnancy, loss to follow-up, 20 weeks' gestation), whichever occurred first. We estimated incidence rate ratios (IRRs) for miscarriage and corresponding 95% CIs using Cox proportional hazards models with GW as the time scale. We used propensity score fine stratification weights to adjust for confounding. MAIN RESULTS AND THE ROLE OF CHANCE: Among 1815 eligible female participants, 75% had received at least one dose of a COVID-19 vaccine by the time of conception. Almost one-quarter of pregnancies resulted in miscarriage, and 75% of miscarriages occurred <8 weeks' gestation. The propensity score-weighted IRR comparing female participants who received at least one dose any time before conception versus those who had not been vaccinated was 0.85 (95% CI: 0.63, 1.14). COVID-19 vaccination was not associated with increased risk of either early miscarriage (GW: <8) or late miscarriage (GW: 8-19). There was no indication of an increased risk of miscarriage associated with male partner vaccination (IRR = 0.90; 95% CI: 0.56, 1.44). LIMITATIONS, REASONS FOR CAUTION: The present study relied on self-reported vaccination status and infection history. Thus, there may be some non-differential misclassification of exposure status. While misclassification of miscarriage is also possible, the preconception cohort design and high prevalence of home pregnancy testing in this cohort reduced the potential for under-ascertainment of miscarriage. As in all observational studies, residual or unmeasured confounding is possible. WIDER IMPLICATIONS OF THE FINDINGS: This is the first study to evaluate prospectively the relation between preconception COVID-19 vaccination in both partners and miscarriage, with more complete ascertainment of early miscarriages than earlier studies of vaccination. The findings are informative for individuals planning a pregnancy and their healthcare providers.

Association between priapism and HIV disease and treatment.

BACKGROUND: Priapism, a urologic emergency, has known associations with certain medical conditions. Many cases are idiopathic, suggesting an opportunity to identify novel risk factors. AIM: We sought to identify medical conditions and pharmaceutical treatments that are associated with priapism using data-mining techniques. METHODS: Using deidentified data in a large insurance claims database, we identified all men (age ≥20 years) with a diagnosis of priapism from 2003 to 2020 and matched them to cohorts of men with other diseases of male genitalia: erectile dysfunction, Peyronie disease, and premature ejaculation. All medical diagnoses and prescriptions used prior to first disease diagnosis were examined. Predictors were selected by random forest, and conditional multivariate logistic regressions were applied to assess the risks of each predictor. OUTCOMES: We identified novel relationships of HIV and some HIV treatments with priapism and confirmed existing associations. RESULTS: An overall 10 459 men with priapism were identified and matched 1:1 to the 3 control groups. After multivariable adjustment, men with priapism had high associations of hereditary anemias (odds ratio [OR], 3.99; 95% CI, 2.73-5.82), use of vasodilating agents (OR, 2.45; 95% CI, 2.01-2.98), use of HIV medications (OR, 1.95; 95% CI, 1.36-2.79), and use of antipsychotic medications (OR, 1.90; 95% CI, 1.52-2.38) as compared with erectile dysfunction controls. Similar patterns were noted when compared with premature ejaculation and Peyronie disease controls. CLINICAL IMPLICATIONS: HIV and its treatment are associated with priapism, which may affect patient counseling. STRENGTHS AND LIMITATIONS: To our knowledge, this is the first study to identify risk factors for priapism utilizing machine learning. All men in our series were commercially insured, which limits the generalizability of our findings. CONCLUSION: Using data-mining techniques, we confirmed existing associations with priapism (eg, hemolytic anemias, antipsychotics) and identified novel relationships (eg, HIV disease and treatment).

Use of phosphodiesterase 5 inhibitors is not associated with ocular adverse events.

BACKGROUND: Phosphodiesterase 5 inhibitor (PDE5i) use has been linked to a number of ocular side effects, such as serous retinal detachment (SRD), retinal vascular occlusion (RVO), and ischemic optic neuropathy (ION). AIM: We investigated the risk for SRD, RVO, and ION in patients using PDE5is. METHODS: We utilized the IBM MarketScan (2007-2021) Commercial and Medicare Supplemental Databases (version 2.0) for this analysis. To estimate overall events risk, Cox proportional hazard models were applied to calculate the hazard ratios (HRs) for erectile dysfunction (ED) diagnosis and the different treatments, adjusting for region, median age, obesity, diabetes mellitus, hyperlipidemia, smoking, hypertension, coronary artery disease, and sleep apnea. Additionally, the same analyses were performed to calculate the HRs for benign prostatic hyperplasia (BPH) diagnosis and the different treatments. OUTCOMES: HRs for SRD, RVO, and ION. RESULTS: In total, 1 938 262 men with an ED diagnosis were observed during the study period. Among them, 615 838 (31.8%) were treated with PDE5is. In total, 2 175 439 men with a BPH diagnosis were observed during the study period. Among them, 175 725 (8.1%) were treated with PDE5is. On adjusted Cox regression analysis, PDE5i use was not associated with SRD, RVO, ION, and any ocular event when compared with ED diagnosis and other ED treatments. Importantly, as the intensity of ED treatment increased, so did the risk of ocular events. In addition, PDE5i use was not associated with SRD and ION when compared with BPH diagnosis and other BPH treatments. In contrast, in patients with BPH, PDE5i use was associated with RVO (HR, 1.14; 95% CI, 1.06-1.23). Importantly, patients with BPH receiving other medical treatment (ie, 5a reductase/alpha blocker; HR, 1.11; 95% CI, 1.06-1.16) or surgical treatment (HR, 1.10; 95% CI, 1.02-1.19) had a higher risk of RVO. CLINICAL IMPLICATIONS: We did not observe any consistent association between PDE5i use and any ocular adverse events (SRD, RVO, and ION). STRENGTHS AND LIMITATIONS: Because we did not have access to the patients' medical records, we recorded outcome definitions using ICD-9 and ICD-10 coding. CONCLUSIONS: Patients using PDE5is for ED or BPH indications did not have an increased risk of ocular events, even when compared with other treatments for ED or BPH.

5-alpha reductase inhibitors (5-ARi) with or without alpha-blockers (α-B) for Benign Prostatic Hyperplasia do NOT lower the risk of incident Bladder Cancer: United States insurance claims data.

BACKGROUND: Chemoprotective effect of 5-alpha reductase inhibitors (5-ARi) on bladder cancer (BCa) risk in men with Benign Prostatic Hyperplasia (BPH) has been explored with conflicting results. We sought to examine the effect of 5-ARi on new BCa diagnoses in a large US database. METHODS: Men ≥ 50 y/o with a prescription for 5-ARi after BPH diagnosis were identified in the IBM® Marketscan® Research de-identified Databases between 2007 and 2016 and matched with paired controls. Incident BCa diagnoses were identified after BPH diagnosis and/or pharmacologic treatment. Multivariable regression modeling adjusting for relevant factors was implemented. Sub-group analyses by exposure risk were performed to explore the association between 5-ARi and BCa over time. Administration of alpha-blockers (α-B) w/o 5-ARi was also examined. RESULTS: In total, n = 24,036 men on 5-ARi, n = 107,086 on 5-ARi plus alpha-blockers, and n = 894,275 without medical therapy for BPH were identified. The percentage of men diagnosed with BCa was 0.8% for the 5-ARi, 1.4% for the 5-ARi + α-B, and 0.6% for the untreated BPH group of incident BCa (adjusted hazard ratio [aHR], 0.90, 95% confidence interval [CI] 0.56 - 1.47), and 1.08, 95%CI 0.89 - 1.30, respectively). This was also true at both shorter (≤ 2 yr) and longer-term (> 2 yr) follow up. In addition, α-B alone had no change in BCa risk (HR 1.06, 0.86-1.30). CONCLUSIONS: We did not find any diminished risk of new BCa in men treated with 5-ARi (i.e., chemoprotective effect). The current report suggests that 5-ARi do not change a man's bladder cancer risk.

Counseling for the man with severe male infertility.

PURPOSE OF REVIEW: This review summarize the proper counseling for men with severe male factor infertility. RECENT FINDINGS: Men who are experiencing infertility should have a semen analysis, the results of which may imply additional investigations, including genetic and hormonal. Moreover, possible modifiable factors that may harm men's reproductive health should be carefully evaluated. Finally, different treatment options are available. SUMMARY: Approximately 15% of couples struggle with infertility. Complete evaluations of both men and women are required to determine the etiology of infertility and determine appropriate treatment.

Removing Implicit Bias From Cardiothoracic Surgery Resident Recruitment: Changing the Paradigm.

INTRODUCTION: The cardiothoracic (CT) surgery workforce continues to suffer from underrepresentation of women and minority physicians. The presence of implicit bias in the recruitment process may impair efforts to enhance the diversity of our training programs. Using a systematic approach, we aimed to investigate and optimize our candidate selection processes to minimize implicit bias. METHODS: Internal review of a single center's CT fellowship program selection process was conducted. Areas of potential bias were evaluated. Specifically, we investigated how interview questions were selected, how candidates were assessed during interviews, and how they were compared after interviews. Proactive measures were implemented to remove identified sources of bias. RESULTS: Several areas of potential bias were identified, including variability in types of questions asked and disparities in how candidates were scored. We noted the presence of potentially gendered language, cultural bias, and stereotyping within traits being scored. With the goals of intentionally promoting diversity and inclusion, we selected five traits as likely predictors of success which served as the framework from which standardized interview questions were created. The interview scoresheet was modified to include all attributes felt to be important, while eliminating irrelevant confounders and language that could carry potential advantage to specific groups. CONCLUSIONS: By implementing strategies to identify and remove sources of implicit bias in the interview and recruitment process, our training program improved its process for the recruitment of a diverse cadre of matriculants. We must aim not only to diversify the composition of our trainee classes, but also to ensure equitable support, mentorship, and sponsorship throughout training and career advancement.

The role of immunotherapy and targeted therapy in the multimodal therapy for resectable lung cancer.

As the immunotherapeutic milieu in resectable nonsmall cell lung cancer continues to evolve, the field of thoracic oncology actively moves towards better patient selection based on biomarkers and oncogenic drivers. In this article, we review the current standard of oncologic care in this population and discuss the ongoing phase III clinical trials investigating the use of immunotherapy or targeted therapy in the perioperative period. We also discuss genotyping initiatives, biomarkers, and trial endpoints.

Salvage surgery in lung cancer following definitive therapies.

Salvage surgery refers to operative resection of persistent or recurrent disease in patients initially treated with intention-to-cure nonoperative management. In non-small-cell lung cancer, salvage surgery may be effective in treating selected patients with locally progressive tumors, recurrent local or locoregional disease, or local complications after nonoperative therapy. Importantly, those patients who may be candidates for salvage surgery are evolving, in terms of disease stage as well as the types of attempted definitive therapy received.

Preconception Antidiabetic Drugs in Men and Birth Defects in Offspring : A Nationwide Cohort Study.

BACKGROUND: Diabetes reduces semen quality and increasingly occurs during reproductive years. Diabetes medications, such as metformin, have glucose-independent effects on the male reproductive system. Associations with birth defects in offspring are unknown. OBJECTIVE: To evaluate whether the risk for birth defects in offspring varies with preconceptional pharmacologic treatment of fathers with diabetes. DESIGN: Nationwide prospective registry-based cohort study. SETTING: Denmark from 1997 to 2016. PARTICIPANTS: All liveborn singletons from mothers without histories of diabetes or essential hypertension. MEASUREMENTS: Offspring were considered exposed if their father filled 1 or more prescriptions for a diabetes drug during the development of fertilizing sperm. Sex and frequencies of major birth defects were compared across drugs, times of exposure, and siblings. RESULTS: Of 1 116 779 offspring included, 3.3% had 1 or more major birth defects (reference). Insulin-exposed offspring (n = 5298) had the reference birth defect frequency (adjusted odds ratio [aOR], 0.98 [95% CI, 0.85 to 1.14]). Metformin-exposed offspring (n = 1451) had an elevated birth defect frequency (aOR, 1.40 [CI, 1.08 to 1.82]). For sulfonylurea-exposed offspring (n = 647), the aOR was 1.34 (CI, 0.94 to 1.92). Offspring whose fathers filled a metformin prescription in the year before (n = 1751) or after (n = 2484) sperm development had reference birth defect frequencies (aORs, 0.88 [CI, 0.59 to 1.31] and 0.92 [CI, 0.68 to 1.26], respectively), as did unexposed siblings of exposed offspring (3.2%; exposed vs. unexposed OR, 1.54 [CI, 0.94 to 2.53]). Among metformin-exposed offspring, genital birth defects, all in boys, were more common (aOR, 3.39 [CI, 1.82 to 6.30]), while the proportion of male offspring was lower (49.4% vs. 51.4%, P = 0.073). LIMITATION: Information on underlying disease status was limited. CONCLUSION: Preconception paternal metformin treatment is associated with major birth defects, particularly genital birth defects in boys. Further research should replicate these findings and clarify the causation. PRIMARY FUNDING SOURCE: National Institutes of Health.

ALDH2 Expression, Alcohol Intake and Semen Parameters among East Asian Men.

PURPOSE: Inactivating mutations in mitochondrial aldehyde dehydrogenase 2 (ALDH2) are highly prevalent. The most common variant allele, ALDH2*2, is present in 40%-50% of East Asians, and causes acetaldehyde accumulation, flushing and tachycardia after alcohol intake. The relationship between alcohol intake and ALDH2 genotype on semen parameters remains unknown. MATERIALS AND METHODS: We conducted a cross-sectional study to determine the association between ALDH2 genotype, alcohol consumption and semen parameters among East Asian men. Volunteers completed a survey and submitted a semen sample for analysis. Participants were genotyped to determine ALDH2 status (ALDH2*1/*1, ALDH2*1/*2, ALDH2*2/*2), and immunohistochemical staining was used to determine protein expression of ALDH2 in spermatozoa. RESULTS: Of 112 men 45 (40.2%) were ALDH2*2 carriers. Among ALDH2*2 carriers, alcohol consumption was associated with significantly lower total sperm motility (median 20% [interquartile range 11%-42%] vs 43% [IQR 31%-57%], p=0.005) and progressive sperm motility (19% [IQR 11%-37%] vs 36% [IQR 25%-53%], p=0.008). Among alcohol consumers, ALDH2*2 carriers had significantly lower total sperm motility (20% [IQR 11%--42%] vs 41% [IQR 19%-57%], p=0.02), progressive sperm motility (19% [IQR 11%-37%] vs 37% [IQR 17%-50%], p=0.02) and total motile sperm count (28 million [M; IQR 9-79M] vs 71M [IQR 23-150M], p=0.05) compared to ALDH2*1/*1 individuals. Secondly, ALDH2 expression in human spermatozoa was significantly lower in ALDH2*2 carriers (ALDH2*1/*1 vs ALDH2*1/*2, p=0.01; ALDH2*1/*1 vs ALDH2*2/*2, p <0.001). CONCLUSIONS: Our findings suggest genotyping ALDH2, coupled with alcohol cessation counseling, may improve semen parameters among men.
