Fejzo MS. Hyperemesis gravidarum theories dispelled by recent research: a paradigm change for better care and outcomes. Trends Mol Med 2024; 30:530-540.

Abstract
Nausea and vomiting (NVP) affect most pregnant women. At the severe end of the clinical spectrum, hyperemesis gravidarum (HG) can be life-threatening. The condition is fraught with misconceptions that have slowed progress and left women undertreated. Herein, recent scientific advances are presented that dispel common myths associated with HG related to maternal/offspring outcomes, etiology, and evolution. There is now strong evidence that (i) HG is associated with poor outcomes, (ii) a common cause of NVP and HG has been identified, and (iii) NVP is likely a protective evolutionary mechanism that occurs throughout the animal kingdom but is no longer necessary for human survival. Therefore, it is encouraging that we are finally on the cusp of testing treatments that may put an end to unnecessary suffering.

Cotinine concentrations in maternal serum and amniotic fluid during pregnancy and risk of testicular germ cell cancer in the offspring: A prospective nested case-control study. Int J Cancer 2024; 154:71-80. [PMID: 37603038 DOI: 10.1002/ijc.34688] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/25/2023] [Revised: 06/26/2023] [Accepted: 06/27/2023] [Indexed: 08/22/2023]
Abstract
Maternal smoking in pregnancy may increase the risk of testicular germ cell cancer (TGCC) in offspring, but current evidence remains inconclusive. We performed a nested case-control study using cotinine measurements in maternal serum and amniotic fluid as a biomarker for tobacco exposure during pregnancy. A total of 654 males with maternal serum (n = 359, ncases/controls = 71/288) and/or amniotic fluid (n = 295, ncases/controls = 66/229) samples were included. Data on TGCC diagnoses and relevant covariates were derived from nationwide Danish health registries. Cotinine was quantified by liquid chromatography tandem mass spectrometry. An adapted cox regression model estimated the risk of TGCC considering active and inactive tobacco use defined according to cotinine concentrations of <, ≥15 ng/ml. Overall, the concentrations of cotinine were comparable in maternal serum and amniotic fluid (medianserum/amniotic fluid : 2.1/2.6 ng/ml). A strong statistically significant correlation was detected in 14 paired samples (Spearman rho: 0.85). Based on maternal serum cotinine concentrations, exposure to active tobacco use was not associated with risk of TGCC in offspring (HR 0.88, 95% CI 0.51; 1.52). Similarly, based on amniotic fluid cotinine concentrations, exposure to active tobacco use was not associated with risk of TGCC (HR 1.11, 95% CI 0.64; 1.95). However, different risks were observed for seminomas and nonseminomas in both matrices, but none were statistically significant. Our findings did not provide convincing evidence supporting that exposure to tobacco during pregnancy is associated with TGCC.

[PMID: 37879293 PMCID: PMC10754053 DOI: 10.1016/j.canep.2023.102472] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/12/2023] [Revised: 10/05/2023] [Accepted: 10/10/2023] [Indexed: 10/27/2023]
Abstract
OBJECTIVE Only a few studies have reported on the association between hyperemesis gravidarum and the risk of childhood cancer. We examined possible associations in this population-based study in Denmark. METHODS Pediatric cancer cases (n = 6420) were ascertained from the Denmark Cancer Registry among children born between 1977 and 2013. Twenty-five controls were matched to each case by sex and birth date from the Central Person Registry (n = 160500). Mothers with hyperemesis gravidarum were ascertained from the National Patient Register. The risk of childhood cancer was estimated using conditional logistic regression. In a separate analysis, we examined pregnancy prescription of antinauseant medications, ascertained from the National Pharmaceutical Register, to determine associations with childhood cancers. RESULTS In Denmark, hyperemesis gravidarum was associated with an increased risk of childhood cancer [all types combined; Odds Ratio (OR) = 1.43, 95% confidence interval (CI) 1.12, 1.81; n = 73 exposed cases). Hyperemesis gravidarum was also associated with an increased risk of neuroblastoma (OR = 2.52, 95% CI 1.00, 6.36; n = 5 exposed cases), acute lymphoblastic leukemia (OR = 1.63, 95% CI 0.98, 2.72; n = 16 exposed cases), and non-Hodgkin's lymphoma (OR = 2.41, 95% CI 0.95, 6.08; n = 5 exposed cases). We observed no childhood cancer risk increase from antinauseant prescriptions (OR = 1.05, 95% CI 0.84, 1.30; n = 91 exposed cases). CONCLUSION Our results are suggestive of an association between hyperemesis gravidarum and the overall cancer risk in offspring, particularly for neuroblastoma. Mothers with hyperemesis gravidarum should be closely monitored and receive appropriate treatment during pregnancy.

MEDICINA (KAUNAS, LITHUANIA) 2023; 59:1305. [PMID: 37512119 PMCID: PMC10383207 DOI: 10.3390/medicina59071305] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/31/2023] [Revised: 07/05/2023] [Accepted: 07/11/2023] [Indexed: 07/30/2023]
Abstract
Background and Objectives: The relationship between male infertility (MI) and testicular cancer (TC) is bilateral. On one hand, it is well-established that patients diagnosed with TC have a high risk of pre- and post-treatment infertility. On the other hand, the risk of developing TC in male infertile patients is not clearly defined. The objective of this review is to analyze the histopathological, etiological, and epidemiological associations between MI and the risk of developing testicular cancer. This review aims to provide further insights and offer a guide for assessing the risk factors for TC in infertile men. Materials and Methods: A comprehensive literature search was conducted to identify relevant studies discussing the relationship between MI and the risk of developing TC. Results: The incidence rates of germ cell neoplasia in situ (GCNIS) appear to be high in infertile men, particularly in those with low sperm counts. Most epidemiological studies have found a statistically significant risk of developing TC among infertile men compared to the general or fertile male populations. The concept of Testicular Dysgenesis Syndrome provides an explanatory model for the common etiology of MI, TC, cryptorchidism, and hypospadias. Clinical findings such as a history of cryptorchidism could increase the risk of developing TC in infertile men. Scrotal ultrasound evaluation for testis lesions and microlithiasis is important in infertile men. Sperm analysis parameters can be useful in assessing the risk of TC among infertile men. In the future, sperm and serum microRNAs (miRNAs) may be utilized for the non-invasive early diagnosis of TC and GCNIS in infertile men. Conclusions: MI is indeed a risk factor for developing testicular cancer, as demonstrated by various studies. All infertile men should undergo a risk assessment using clinical examination, ultrasound, and semen parameters to evaluate their risk of TC.

Abstract
Background: Maternal exposure to cigarette smoke in pregnancy may play a role in the development of testicular cancer in offspring. An updated and comprehensive systematic review of the available evidence is needed. Objective: To identify and evaluate current evidence on maternal exposure to cigarette smoke during pregnancy and testicular cancer in offspring. Methods: A systematic search of English peer-reviewed original literature in PubMed through a block search approach. Publications were considered if assessing maternal exposure to cigarette smoke and the risk of testicular cancer in offspring. Results: Among the 636 identified records, 14 publications were eligible for review and 10 for meta-analysis. Quality assessment of the publications was conducted. Most included publications were case-control studies (n = 11, 79%), while the remaining were ecological studies (n = 3, 21%). Completeness of reporting was high, but more than half were considered subject to potential bias. The trend synthesis showed that half (n = 7) of the included publications demonstrated a higher risk of testicular cancer in the sons of mothers exposed to cigarette smoke during pregnancy. The meta-analysis generated an overall summary risk estimate of 1.00 (95% CI: 0.88; 1.15) (n = 10 publications), with a lower risk for seminoma (0.79, 95% CI: 0.59; 1.04) and nonseminoma (0.96, 95% CI: 0.74; 1.26) (n = 4 publications). Conclusions: This systematic review did not provide evidence of an association between maternal exposure to cigarette smoke and risk of testicular cancer in offspring. An overall positive trend was suggested, but it had low statistical precision. The methodological limitations across publications encourage further research based on valid exposure data.

Abstract
OY-TES-1 is reportedly involved in carcinogenesis and spermatogenesis. However, the tissue distribution of OY-TES-1 in the normal human body remains elusive. This study detected OY-TES-1 expression in human fetal and adult normal tissues by immunohistochemistry. We identified a general principle of OY-TES-1 expression. The expression of OY-TES-1 was found in neurons, smooth muscle cells, and cardiac muscle cells from both fetuses and adults. The connective tissue showed no specific staining throughout the fetal and adult samples. With OY-TES-1-positive staining of the epithelium irregular, OY-TES-1 was strongly expressed in the epithelium of the skin and bladder, as well as hepatocytes, pancreatic islets, and acinous cells during the fetal stage but was not detected in the postnatal period. In contrast to the epithelium of blood vessels, the fetal and adult central hepatic vein and glomeruli showed negative expression of the OY-TES-1 protein. Sex-dimorphism was observed in the distribution of OY-TES-1 in male and female germ cells. Collectively, our results indicate that OY-TES-1 is a member of the cancer-testis antigen and autoantigen, with tissue-specific and period-specific expression patterns, revealing potential contributions of OY-TES-1 to the diagnosis and therapeutic treatment for neoplasms and infertility.

Long-term health outcomes of children born to mothers with hyperemesis gravidarum: a systematic review and meta-analysis. Am J Obstet Gynecol 2022; 227:414-429.e17. [PMID: 35367190 DOI: 10.1016/j.ajog.2022.03.052] [Citation(s) in RCA: 11] [Impact Index Per Article: 5.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/17/2021] [Revised: 03/16/2022] [Accepted: 03/22/2022] [Indexed: 11/29/2022]
Abstract
OBJECTIVE Hyperemesis gravidarum is characterized by severe nausea and vomiting in pregnancy, frequently resulting in severe maternal nutritional deficiency. Maternal undernutrition is associated with adverse offspring health outcomes. Whether hyperemesis gravidarum permanently affects offspring health remains unclear. This review aimed to evaluate the effects of maternal hyperemesis gravidarum on offspring health. DATA SOURCES MEDLINE and Embase were searched from inception to September 6, 2021. STUDY ELIGIBILITY CRITERIA Studies reporting on health at any age beyond the perinatal period of children born to mothers with hyperemesis gravidarum were included. METHODS Two reviewers independently selected studies and extracted data. The Newcastle-Ottawa Quality Assessment Scale was used to assess risk of bias. We conducted a narrative synthesis and meta-analysis where possible. In meta-analyses with high heterogeneity (I2>75%), we did not provide a pooled odds ratio. RESULTS Nineteen studies were included in this systematic review (n=1,814,785 offspring). Meta-analysis (n=619, 2 studies: 1 among adolescents and 1 among adults) showed that hyperemesis gravidarum was associated with anxiety disorder (odds ratio, 1.74; 95% confidence interval, 1.04-2.91; I2, 0%) and sleep problems in offspring (odds ratio, 2.94; 95% confidence interval, 1.25-6.93; I2, 0%). Hyperemesis gravidarum was associated with testicular cancer in male offspring aged up to 40 years on meta-analysis (5 studies, n=20,930 offspring), although heterogeneity was observed on the basis of a wide 95% prediction interval (odds ratio, 1.60; 95% confidence interval, 1.07-2.39; I2, 0%; 95% prediction interval, 0.83-3.08). All 6 studies reporting on attention deficit (hyperactivity) disorder and autism spectrum disorder reported an increase among children of mothers with hyperemesis gravidarum in comparison with children of unaffected mothers. Meta-analysis showed high heterogeneity, precluding us from reporting a pooled odds ratio. Most studies reporting on cognitive and motor problems found an increase among hyperemesis gravidarum-exposed children. One study investigated brain structure and found smaller cortical volumes and areas among children from hyperemesis gravidarum-affected pregnancies than among those from unaffected pregnancies. Studies evaluating anthropometry and cardiometabolic disease risk of hyperemesis gravidarum-exposed children had inconsistent findings. CONCLUSION Our systematic review showed that maternal hyperemesis gravidarum is associated with small increases in adverse health outcomes among children, including neurodevelopmental disorders, mental health disorders, and possibly testicular cancer, although evidence is based on few studies of low quality.

Proximity to endocrine-disrupting pesticides and risk of testicular germ cell tumors (TGCT) among adolescents: A population-based case-control study in California. Int J Hyg Environ Health 2021; 239:113881. [PMID: 34839102 DOI: 10.1016/j.ijheh.2021.113881] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/20/2021] [Revised: 10/28/2021] [Accepted: 11/08/2021] [Indexed: 11/26/2022]
Abstract
BACKGROUND The incidence of testicular germ cell tumors (TGCT) is increasing steadily in the United States, particularly among Latinos. TGCT is thought to be initiated in utero and exposure to endocrine-disrupting chemicals, suspected contributors to TGCT pathogenesis, during this critical developmental period may contribute to the rise. OBJECTIVES To assess the relationship between fetal exposure to agricultural endocrine-disrupting pesticides (EDPs) and TGCT risk among adolescents in a diverse population in California. METHODS We conducted a registry-based case-control study of TGCT. Cases, diagnosed between 1997 and 2011, were 15-19 years of age (n = 381). Controls were matched on birth year and race/ethnicity (n = 762). Quantities (kilograms) of 33 pesticides applied within 3 km and 1 km radii of each individual's address before birth were estimated using the Pesticide Use Reporting database. Odds ratios (OR), 95% confidence intervals (CI), and population attributable risk (PAR) were calculated for each EDP (using log-2 transformed values). Risk models considered race/ethnicity, birth year, and neighborhood socioeconomic status. RESULTS A doubling of nearby acephate applications (3 km and 1 km radii) and malathion applications (1 km radius) was associated with increased risks of TGCT among Latinos only (OR = 1.09; 95% CI:1.01-1.17; 1.30; 95% CI:1.08-1.57, and 1.19; 95% CI:1.01-1.39, respectively), whereas application of carbaryl within a 3 km radius increased TGCT risk in non-Latinos only (OR = 1.14, 95% CI:1.01-1.28). We estimate that acephate was associated with approximately 10% of the TGCT PAR, malathion with 3% and carbaryl with 1%. CONCLUSIONS TGCT among adolescents in California was associated with prenatal residential proximity to acephate and malathion among Latinos, and with carbaryl among non-Latinos. These results suggest that the rise in TGCT risk among Latinos may be associated with exposure to these pesticides.

Abstract
Male factor infertility is a common problem. Evidence is emerging regarding the spectrum of systemic disease and illness harbored by infertile men who otherwise appear healthy. In this review, we present evidence that infertile men have poor overall health and increased morbidity and mortality, increased rates of both genitourinary and non-genitourinary malignancy, and greater risks of systemic disease. The review also highlights numerous genetic conditions associated with male infertility as well as emerging translational evidence of genitourinary birth defects and their impact on male infertility. Finally, parallels to the overall health of infertile women are presented. This review highlights the importance of a comprehensive health evaluation of men who present for an infertility assessment.

Abstract
PURPOSE We aimed to investigate the association of maternal nausea and vomiting during pregnancy (NVP) with infant growth in the first 24 months of life and compare the effect of fetal gender. METHODS This prospective cohort study was conducted in Zhoushan Maternal and Child Health Hospital, Zhejiang, from 2011 to 2018. 1942 pairs of singleton newborns and their mothers were selected as participants. Main outcomes were gestational weight gain (GWG), birth outcomes (birthweight and gestational age) and infant growth [weight, height, weight/height-for-age Z score (WAZ/HAZ), the weight gain during childhood]. The associations of NVP with birth outcomes and infant growth at children's age of 1, 3, 6, 12, 18, and 24 months were analyzed by multivariable regression models. RESULTS Of the 1942 women, 1395 had NVP at first trimester (T1) and among them, 210 still experienced NVP at second trimester (T2). Compared with women without NVP, women experienced severe NVP at T1 were related with lower total GWG. Mild and moderate NVP at T1 were negatively associated with lower birthweight among women with male infants. Female infants exposed to maternal NVP at T1, especially for severe degree, were showed greater weight, WAZ, height, HAZ, and weight gain after 1 year old (at age of 12, 18, 24 months). No association between maternal NVP and infant growth was observed among male infants. CONCLUSION Exposure to NVP at T1 was, respectively, associated with lower GWG. Favorable influence of NVP at T1 on infant growth was observed among female offspring.

Incident testicular cancer in relation to using marijuana and smoking tobacco: A systematic review and meta-analysis of epidemiologic studies. Urol Oncol 2020; 38:642.e1-642.e9. [PMID: 32409200 DOI: 10.1016/j.urolonc.2020.03.013] [Citation(s) in RCA: 17] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/21/2019] [Revised: 03/11/2020] [Accepted: 03/17/2020] [Indexed: 11/18/2022]
Abstract
BACKGROUND Recent epidemiologic studies identified credible associations between marijuana smoking and risk of nonseminomatous testicular germ cell tumors (TGCTs), but did not distinguish exposure to cannabinoid compounds from exposure to other constituents of smoke. METHODS We implemented a systematic review of scholarly literature followed by random effects meta-analysis to quantitatively synthesize published data relating incident TGCT to each of 2 exposure histories: ever using marijuana, and ever smoking tobacco. RESULTS We identified four epidemiologic studies of marijuana use and 12 of tobacco smoking. Summary data concur with earlier reports of a specific association of marijuana use with nonseminoma, summary odds ratio [sOR] = 1.71 (95% confidence interval [CI] 1.12-2.60), and identify a positive association, sOR = 1.18 (95% CI 1.05-1.33), between tobacco smoking and all TGCT. CONCLUSIONS Available data accord with positive associations between incident TGCT and each exposure, implicating both cannabinoid compounds and other constituents of smoke. Etiologic interpretation awaits epidemiologic studies that assess associations between tobacco smoking and nonseminomatous TGCT, investigating not only these exposures but also both co-use of tobacco and marijuana and smoke-free sources of cannabinoids, while adequately evaluating potential confounding among all of these exposures.

Abstract
Objective To examine incidence and survival of testicular cancer in New Mexico, overall and separately for border and non-border counties. Methods Incidence and 5-year survival rates for testicular cancer were obtained from the SEER18 database using the SEER*Stat program following established NCI protocols. Incidence data were compared using Student's t-test. Age-adjusted 5-year survival and Kaplan-Meier method were used to estimate survival. Log-rank tests were used to compare survival for New Mexico to the remaining17 geographical areas of the SEER 18 and for the New Mexico border counties to the New Mexico non-border counties. Odds ratios were used to compare testicular stage at diagnosis. Cox proportional hazards regression was performed to account for race/ethnicity, and border status. Results From 2000-2015, New Mexico had a testicular cancer incidence rate of 6.3 per 100,000 people, significantly higher than SEER18 (P<.001). The 5-year survival rate in New Mexico did not differ significantly from the SEER18 (P=.3). Border Hispanics had a lower survival rate than border non-Hispanic populations (P=.03). From 2000-2018, New Mexico had a significantly higher proportion of distant cancers than the SEER18 (OR: 1.29, 95% CI: 1.08 to 1.53, P=.005). Conclusions The higher incidence of testicular cancer in New Mexico does not appear to have a clear explanation based on the current understanding of risk factors; however, the increased incidence in New Mexico does not appear to be associated with increased mortality. The higher proportion of advanced testicular cancers in New Mexico may represent a delay in diagnosis. The increased mortality rate seen in Hispanic border populations may be due in part to barriers to care.

Abstract
BACKGROUND Testicular cancer (TC) is the most common malignancy in young adult men, and in many countries the incidence rates of testicular cancer have been increasing since the middle of the twentieth century. Since disease presentation and tumor progression patterns are often heterogeneous across racial groups, there may be important racial differences in recent TC trends. METHODS In this study, Surveillance, Epidemiology, and End Results (SEER) data on TC patients diagnosed between 1973 and 2015 were analyzed, including the following racial/ethnic groups: non-Hispanic whites (NHW), Hispanic whites (HW), blacks, and Asians and Pacific Islanders (API). Patient characteristics, age-adjusted incidence rates, and survival were compared across racial groups. A multivariate Cox model was used to analyze the survival data of TC patients, in order to evaluate racial differences across several relevant factors, including marital status, age group, histologic type, treatment, stage, and tumor location. RESULTS NHWs had the highest incidence rates, followed by blacks, HWs, and APIs. There were significant survival differences among the racial groups, with NHWs having the highest survival rates and blacks having the lowest. CONCLUSION An analysis of SEER data showed that racial differences existed among TC patients in the United States with respect to patient characteristics, incidence, and survival. The results can be useful to stakeholders interested in reducing the burden of TC morbidity and mortality.

Abstract
Background This study aims to explore and project the temporal trends in incidence and mortality of testicular cancer. Moreover, it can provide theoretical guidance for the rational allocation of health resources. Methods This study analyzed existing data on testicular cancer morbidity and mortality from 1990 to 2016 and predicted time-varying trends of age-standardized incidence rate (ASIR) and age-standardized death rate (ASDR) from 2017 to 2030 in different ages, regions and sociodemographic index (SDI) quintile sub-groups. Result Globally, numbers of testicular cancer cases in 2016 [66,833; 95% uncertainty interval (UI), 64,487–69,736] are 1.8 times larger than in 1990 (37,231; 95% UI, 36,116–38,515). The testicular cancer-related death cases increased slightly from 8,394 (95% UI, 7,980–8,904) in 1990 to 8,651 (95% UI, 8,292–9,027) in 2016. In aspect of ASIR, the data showed an up-trend from 0.74 (95% UI, 0.72–0.77) in 1990 to 0.88 (95% UI, 0.85–0.92) in 2016. The ASDR of testicular cancer declined from 0.18 (95% UI, 0.17–0.19) in 1990 to 0.12 (95% UI, 0.11–0.12) in 2016. From 2017 to 2030, predictions of trends in testicular cancer indicate that the ASIRs of most SDI countries are rising, but the ASDRs trends in testicular cancer will decrease. Conclusions By analyzing the available and reliable data in different ages, regions and SDI, this study shows a significant upward trend in incidence and a slow upward trend in mortality of testicular cancer from 1990 to 2016, and simultaneously, predicts the increase of ASIR and the downward trend of ASDR in 2017–2030.

Abstract
BACKGROUND Studies have suggested an association between prenatal hormonal environment and anogenital distance (AGD). We aimed to study the association between AGD and health characteristics in adult women. METHODS In this prospective cohort AGD was measured in 300 parturients during the years 2000-2001. In December 2017, study participants` hospital records were abstracted and medical diagnoses grouped into major categories, including gynecological, cardiovascular, and other. Associations between AGD and the morbidities categories were evaluated using multivariable survival models, which adjusted for confounding variables. RESULTS Participants were 44.3 ± 5.4 years old with mean AGD 40.3 mm (±10.7 mm). Women with below vs. above mean AGD were more likely to develop gynecological morbidities (39.9% vs. 27.1%, adjusted Hazard ratio 1.82; 95%CI 1.08-3.06). CONCLUSIONS Women with short AGD are at increased risk for gynecological morbidities. AGD should be studied further, and may possibly be used for screening of women at risk for these conditions.

Abstract
Background Early exposure to estrogen-like compounds has been implicated in the etiology of testicular cancer, but individual level epidemiologic data addressing this hypothesis are scarce. The synthetic estrogen diethylstilbestrol (DES) was administered during pregnancy from 1948 to 1971, but sequelae of in utero exposure have been more extensively characterized in females than in males. Methods By systematic review, we sought to identify all epidemiologic research relating testicular cancer to a history of in utero exposure to diethylstilbestrol. Identified studies were critically appraised to assemble a set of nonredundant data in which any in utero exposure to DES was compared between men with incident testicular cancer and cancer-free men. These data were synthesized using random effects meta-analysis to estimate the summary association between in utero DES exposure and testicular cancer. Results By meta-analysis of data from the six qualifying studies, the summary odds ratio estimate of the in utero DES-testicular cancer association was 2.98 (95% confidence interval = 1.15 to 7.67). Conclusions Results of this comprehensive meta-analysis accord with a threefold increase in testicular cancer risk among men who were exposed in utero to DES, implicating early hormonal exposures in etiology of testicular cancer. Because use of DES ceased in 1971, this work may provide the most comprehensive estimate of this association that will be made.

Abstract
The purpose of this study was to follow up on the reporting of neurodevelopmental disorders in children exposed in utero to Hyperemesis Gravidarum (HG). This was an exploratory descriptive study whereby neurodevelopmental outcomes of 267 children delivered by 177 mothers with HG were compared to neurodevelopmental outcomes from 93 children delivered by 60 unaffected mothers. Similar to at age 8, the children (now 12) exposed in utero to HG had over 3-fold increase in odds of neurodevelopmental disorders including attention, anxiety, sensory, sleep difficulty, and social development delay/social anxiety. However, with the longer follow-up, there was also a significant increase in Autism Spectrum Disorder (ASD), reported in 22/267 (8%) of children exposed to HG in utero and no unexposed children. As early intervention for ASD can be critical to prognosis, larger studies are urgently needed to determine whether ASD is associated with exposure to HG.

Sulforaphane as anticancer agent: A double-edged sword? Tricky balance between effects on tumor cells and immune cells. Adv Biol Regul 2018; 71:79-87.

Abstract
Sulforaphane (SFN) is a naturally occurring isothiocyanate derived from cruciferous vegetables such as broccoli. It has been reported to inhibit the growth of a variety of cancers, such as breast, prostate, colon, skin, lung, gastric or bladder cancer. SFN is supposed to act primarily as an antioxidant due to the activation of the Nrf2-Keap1 signaling pathway. This enhances the activity of phase II detoxifying enzymes and the trapping of free radicals. Finally, SFN induces cell cycle arrest or apoptosis of tumor cells. Here, we discuss effects of SFN on the immune defense system. In contrast to the situation in tumor cells, SFN acts pro-oxidatively in primary human T cells. It increases intracellular ROS levels and decreases GSH, resulting in inhibition of T cell activation and T cell effector functions. Regarding the use of SFN as an "anticancer agent" we conclude that SFN could act as a double-edged sword. On the one hand it reduces carcinogenesis, on the other hand it blocks the T cell-mediated immune response, the latter being important for immune surveillance of tumors. Thus, SFN could also interfere with the successful application of immunotherapy by immune checkpoint inhibitors (e.g. CTLA-4 antibodies and PD-1/PD-L1 antibodies) or CAR T cells. Therefore, a combination of SFN with T cell-mediated cancer immunotherapies does not seem advisable.

Abstract
BACKGROUND The etiology of testicular germ cell tumors (TGCT) is poorly understood, however, exposure to endocrine disrupting chemicals (EDCs) may be related to increased risk. Personal care products, some of which contain EDCs, are widely used on a daily basis and are known to cross the placenta, be present in breastmilk, and are capable of inducing reproductive tract abnormalities. To determine the association between personal care product use during pregnancy and breastfeeding and TGCT risk, an analysis among mothers of TGCT cases and controls was conducted. METHODS The US Servicemen's Testicular Tumor Environmental and Endocrine Determinants (STEED) study enrolled TGCT cases and controls and their mothers between 2002 and 2005. The current analysis examined personal care product use during pregnancy among 527 mothers of TGCT cases and 562 mothers of controls. Odds ratios (ORs) and 95% confidence intervals (CIs) were calculated using unconditional logistic regression adjusting for identified covariates. RESULTS Maternal use of face lotion more than one time per week was associated with a significantly increased risk of TGCT (OR: 1.42, 95% CI: 1.08-1.86, p-trend: 0.01). None of the other products examined (perfume, hairspray, nail polish, hair dye, permanent wave, body lotion, deodorant, sunscreen) were associated with TGCT risk. CONCLUSIONS Frequent exposure to face lotion during pregnancy and while breastfeeding may be associated with increased TGCT risk. Further investigation into the endocrine disrupting effects of personal care products is warranted.

Abstract
Background: Studies of family history of cancer in paediatric germ cell tumours (GCTs) are few, and none has had sufficient sample size to specifically evaluate family history of GCT. Methods: We utilised family history data from a paediatric GCT study to calculate standardised incidence ratios (SIR) for GCT and other cancers using age- and sex-specific incidence rates from the SEER Program. Results: This analysis included 7998 relatives of paediatric GCT probands. We observed a higher number of GCT cases than expected in male and female relatives of probands (SIR=2.38, 95% CI 1.25, 3.51 for males; SIR=14.3, 95% CI 0.29, 28.4 for females). Further, we observed a particularly strong SIR for relatives of probands with intracranial GCT (SIR=8.07, 95% CI 3.51, 12.6). The SIR for relatives of probands with ovarian GCT was also elevated but did not reach statistical significance (SIR 4.35, 95% CI 0-9.27). Other notable associations include elevated SIRs for melanoma in male relatives and reduced SIRs for lymphatic/haematologic malignancies in male and female relatives. Conclusions: These results support the hypothesis that familial aggregation of GCT occurs in males and females.

Abstract
Testicular germ cell tumors (TGCT) are the most frequent cancer among young men, with increasing incidence worldwide. Advanced paternal age has been linked to adverse health outcomes in offspring, but reports on the association of paternal age with TGCT are few and inconsistent. We aimed to examine the relationship of paternal age (PAB) at birth with the risk of TGCT and by histologic type: seminoma and non-seminoma. A population-based cohort of 1,056,058 males, examined at ages 16-19 between the years 1980-2011, was linked to the Israel National Cancer Registry to obtain incident TGCT through 2012. We applied multivariable Cox regression. During 16.5 million person-years of follow-up, 1247 incident cases (604 seminomas and 643 non-seminomas) were detected. Increasing PAB was linearly associated with lower risk of TGCT (HRper year = 0.983, 95% CI: 0.974-0.993, p = 0.001), after adjustment for year of birth, years of education, height, cryptorchidism history and origin, and also with additional adjustment for maternal age at birth (MAB) (HRper year = 0.980: 0.965-0.995, p = 0.008). The association was stronger for seminoma (HRper year = 0.968: 0.946-0.989, p = 0.004) and persisted in a subset adjusted for sibship size (HRper year = 0.950: 0.917-0.983, p = 0.003). In the fully adjusted model, young PAB (15-24 vs. ≥30) was a risk factor for seminoma (HR = 1.41: 1.07-1.85, p = 0.014). In models adjusted for PAB, MAB was not associated with risk of TGCT. In conclusion, our findings suggest that young paternal age is a risk factor of TGCT, especially seminoma. The findings warrant further investigation into the possible impact of young paternal age on their offsprings' testes.

Abstract
Germ cell tumors (GCT) are a rare form of childhood cancer that originate from the primordial germ cell. Recent genome-wide association studies (GWAS) have identified susceptibility alleles for adult testicular GCT (TGCT). We test whether these SNPs are associated with GCT in pediatric and adolescent populations. This case-parent triad study includes individuals with GCT diagnosed between ages 0 and 19. We evaluated 26 SNPs from GWAS of adult TGCT and estimated main effects for pediatric GCT within complete trios (N = 366) using the transmission disequilibrium test. We used Estimation of Maternal, Imprinting and interaction effects using Multinomial modelling to evaluate maternal effects in non-Hispanic white trios and dyads (N = 244). We accounted for multiple comparisons using a Bonferroni correction. A variant in SPRY4 (rs4624820) was associated with reduced risk of GCT (OR [95% CI]: 0.70 [0.57, 0.86]). A variant in BAK1 (rs210138) was positively associated with GCT (OR [95% CI]: 1.70 [1.32, 2.18]), with a strong estimated effect for testis tumors (OR [95% CI]: 3.31 [1.89, 5.79]). Finally, a SNP in GAB2 (rs948662) was associated with increased risk for GCT (OR [95% CI]: 1.56 [1.20, 2.03]). Nominal associations (P < 0.05) were noted for eight additional loci. A maternal effect was observed for KITLG SNP rs4474514 (OR [95% CI]: 1.66 [1.21, 2.28]) and a paternal parent-of-origin effect was observed for rs7221274 (P = 0.00007), near TEX14, RAD51C, and PPM1E. We observed associations between SNPs in SPRY4, BAK1, and GAB2 and GCTs. This analysis suggests there may be common genetic risk factors for GCT in all age groups.

Abstract
Smoking is a known modifiable risk factor in the development of genitourinary malignancies. Although the association has long been supported by numerous research studies, the impact of smoking cessation on the decreased risk of genitourinary malignancies is less well studied. PubMed databases were searched using the terms smoking, smoking cessation, bladder cancer, kidney cancer, prostate cancer, penile cancer, testicular cancer, their synonyms, and also targeted manual searches to perform a literature review in order to summarize the benefits of cessation on disease progression and patient outcomes including survival and morbidities. Our review yielded substantial evidence highlighting the improved outcomes observed in those diagnosed with bladder, renal, and prostate cancers. The risk of bladder cancer is reduced by up to 60% in those who were able to quit for 25 years and the risk of kidney malignancy was reduced by 50% in those who abstained from smoking for 30 years. A similar trend of reduced risk was observed for prostate cancer with those who quit for more than 10 years, having prostate cancer mortality risks similar to those that never smoked. Although the data were encouraging for bladder, renal, and prostate malignancies, there are comparatively limited data quantifying the benefits of smoking cessation for penile and testicular cancers, highlighting an opportunity for further study. The role of urologists and their impact on their patients' likelihood to quit smoking shows more than half of urologists never discuss smoking cessation upon diagnosis of a malignancy. Most urologists said they did not provide cessation counseling because they do not believe it would alter their patients' disease progression. Studies show urologists have more influence at changing their patients' smoking behaviors than their primary care physicians. The diagnosis of cancer may lead to a teachable moment resulting in increased smoking quit rates. Furthermore, implementing a brief 5-minute clinic counseling session increases quit attempts and quit rates. Diagnosis of genitourinary cancers and the following appointments for treatment provide a unique opportunity for urologists to intervene and affect the progression and outcome of disease.

Critical Function of PRDM2 in the Neoplastic Growth of Testicular Germ Cell Tumors. BIOLOGY 2016; 5:biology5040054.

Abstract
Testicular germ cell tumors (TGCTs) derive from primordial germ cells. Their maturation is blocked at different stages, reflecting histological tumor subtypes. A common genetic alteration in TGCT is a deletion of the chromosome 1 short arm, where the PRDM2 gene, belonging to the Positive Regulatory domain gene (PRDM) family, is located. Expression of PRDM2 gene is shifted in different human tumors, where the expression of the two principal protein forms coded by PRDM2 gene, RIZ1 and RIZ2, is frequently unbalanced. Therefore, PRDM2 is actually considered a candidate tumor suppressor gene in different types of cancer. Although recent studies have demonstrated that PRDM gene family members have a pivotal role during the early stages of testicular development, no information are actually available on the involvement of these genes in TGCTs. In this article we show by qRT-PCR analysis that PRDM2 expression level is modulated by proliferation and differentiation agents such as estradiol, whose exposure during fetal life is probably an important risk factor for TGCTs development in adulthood. Furthermore in normal and cancer germ cell lines, PRDM2 binds estradiol receptor α (ERα) and influences proliferation, survival and apoptosis, as previously reported using MCF-7 breast cancer cell line, suggesting a potential tumor-suppressor role in TGCT formation.

The epidemiologic evidence linking prenatal and postnatal exposure to endocrine disrupting chemicals with male reproductive disorders: a systematic review and meta-analysis. Hum Reprod Update 2016; 23:104-125. [PMID: 27655588 PMCID: PMC5155570 DOI: 10.1093/humupd/dmw036] [Citation(s) in RCA: 179] [Impact Index Per Article: 22.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/27/2016] [Revised: 08/22/2016] [Accepted: 08/31/2016] [Indexed: 12/11/2022] Open
Abstract
BACKGROUND More than 20 years ago, it was hypothesized that exposure to prenatal and early
postnatal environmental xenobiotics with the potential to disrupt endogenous
hormone signaling might be on the causal path to cryptorchidism, hypospadias, low
sperm count and testicular cancer. Several consensus statements and narrative
reviews in recent years have divided the scientific community and have elicited a
call for systematic transparent reviews. We aimed to fill this gap in knowledge in
the field of male reproductive disorders. OBJECTIVE AND RATIONALE The aim of this study was to systematically synthesize published data on the risk
of cryptorchidism, hypospadias, low sperm counts and testicular cancer following
in utero or infant exposure to chemicals that have been
included on the European Commission's list of Category 1 endocrine
disrupting chemicals defined as having documented adverse effects due to endocrine
disruption in at least one intact organism. SEARCH METHODS A systematic literature search for original peer reviewed papers was performed in
the databases PubMed and Embase to identify epidemiological studies reporting
associations between the outcomes of interest and exposures documented by
biochemical analyses of biospecimens including maternal blood or urine, placenta
or fat tissue as well as amnion fluid, cord blood or breast milk; this was
followed by meta-analysis of quantitative data. OUTCOMES The literature search resulted in 1314 references among which we identified 33
papers(28 study populations) fulfilling the eligibility criteria. These provided
85 risk estimates of links between persistent organic pollutants and rapidly
metabolized compounds (phthalates and Bisphenol A) and male reproductive
disorders. The overall odds ratio (OR) across all exposures and outcomes was 1.11
(95% CI 0.91–1.35). When assessing four specific chemical subgroups
with sufficient data for meta-analysis for all outcomes, we found that exposure to
one of the four compounds, p,p′-DDE, was related to an elevated risk: OR
1.35 (95% CI 1.04–1.74). The data did not indicate that this
increased risk was driven by any specific disorder. WIDER IMPLICATIONS The current epidemiological evidence is compatible with a small increased risk of
male reproductive disorders following prenatal and postnatal exposure to some
persistent environmental chemicals classified as endocrine disruptors but the
evidence is limited. Future epidemiological studies may change the weight of the
evidence in either direction. No evidence of distortion due to publication bias
was found, but exposure–response relationships are not evident. There are
insufficient data on rapidly metabolized endocrine disruptors and on specific
exposure–outcome relations. A particular data gap is evident with respect
to delayed effects on semen quality and testicular cancer. Although high quality
epidemiological studies are still sparse, future systematic and transparent
reviews may provide pieces of evidence contributing to the narrative and weight of
the evidence assessments in the field.

Abstract
Lactitol is a disaccharide sugar alcohol (polyol) which is derived from lactose by catalytic hydrogenation and which may be used as a noncariogenic, reduced calorie sugar substitute in different foods. In the context of the safety evaluation of lactitol, a chronic carcinogenicity/toxicity study was conducted in a Wistar-derived strain of rats. In addition to effects that occur commonly in rats fed high doses of polyols, an increased incidence of Leydig cell tumors was observed in rats fed a diet with 10% lactitol for their lifetime. A comparison group receiving a diet with 20% lactose exhibited the same effect. At the 5% dose level of lactitol, no testicular changes were seen. Although lactitol is not genotoxic in standard in vitro tests and was also not associated with tumor formation in female rats and mice of either sex, it was necessary to assess the relevance of the testicular neoplastic growth for human safety. A comparative evaluation of the spontaneous and chemically induced formation of Leydig cell tumors in rats and humans demonstrates that the spontaneous occurrence is extremely low in humans but rather high in rats. Chemical agents or experimental conditions that in rats are associated with interstitial cell hyperplasia or neoplasia have not been associated with similar effects in humans. This is also true for lactose which, in Western countries, is consumed regularly and in substantial amounts with dairy products. Since lactitol is essentially not hydrolyzed in the small intestine, it gains access to the metabolism only after fermentation by the intestinal flora. It is therefore reasonable to assume that the testicular effects of lactitol and lactose were mediated by changes in the digestive tract such as by the known increase of calcium absorption which occurs in lactitol- and lactose-fed rats but not in humans or by effects of these compounds on the enterohepatic cycling of steroid hormones. Although these mechanisms are not yet elucidated, the available data on Leydig cell tumors indicate that the effects seen in male rats are not relevant to humans. The major lines of evidence supporting the human safety of lactitol and lactose are: (1) the lack of genotoxicity of lactitol, (2) the rat specificity of the testicular effects of lactose and lactitol, (3) the long history of safe consumption of lactose in humans, (4) the insensitivity of the human Leydig cells to agents and conditions that are known to cause neoplastic growth of Leydig cells in rats, (5) the generally very low spontaneous incidence of Leydig cell tumors in the human population, and (6) the absence of any epidemiological evidence establishing a link between nutritional factors and the occurrence of Leydig cell tumors in humans.

Abstract
Study of the joint action of xenobiotics is important to fully explore their toxicity and complete risk analysis. In this study, we investigated the effects of low-dose and combined exposure of bisphenol A (BPA) and diethylstilbestrol (DES) on the reproductive system in adult male rats. The results showed that the sperm motility decreased in the BPA/DES and combined groups. Sperm deformity ratios and histological lesions of the testes were significantly higher and more significant, respectively, in the combined group compared with the single treated groups. No dose-effect relationship or significant additive effect on serum hormone levels was observed after combined exposure to BPA/DES. Ultrastructural results showed lesions of the Sertoli and Leydig cells, mainly in the endoplasmic reticulum (ER), in all treated groups. ER stress molecular sensor IRE1 was phosphorylated and activated after BPA and DES treatment in this study. The protein levels of ES stress molecular marker CHOP were significantly up-regulated after exposure to BPA, DES, and BPA and DES combined. These findings indicate that ER stress is important in BPA/DES-induced damage in rat testes. Low-dose and combined exposure to BPA and DES may have toxic effects on male fertility in the adult population.

Abstract
Nausea and occasional vomiting in early pregnancy (NVP) are common. When vomiting is severe or protracted, it is referred to as hyperemesis gravidarum (HG). HG affects up to 3% of pregnancies and is characterized by weight loss, dehydration, electrolyte imbalance, and the need for hospital admission. HG has significant consequences for maternal well-being, is associated with adverse birth outcomes, and leads to major health care costs. Treatment options are symptomatic, hampered by the lack of evidence-based options including studies on nutritional interventions. One of the reasons for this lack of evidence is the use of a broad range of definitions and outcome measures. An internationally accepted definition and the formulation of core outcomes would facilitate meta-analysis of trial results and implementation of evidence in guidelines to ultimately improve patient care.

Abstract
Malignant testicular germ cell tumors (TGCT) are the most frequent cancers in Caucasian males (20-40 years) with an 70% increasing incidence the last 20 years, probably due to combined action of (epi)genetic and (micro)environmental factors. It is expected that TGCT have carcinoma in situ(CIS) as their common precursor, originating from an embryonic germ cell blocked in its maturation process. The overall cure rate of TGCT is more than 90%, however, men surviving TGCT can present long-term side effects of systemic cancer treatment. In contrast, men diagnosed and treated for CIS only continue to live without these long-term side effects. Therefore, early detection of CIS has great health benefits, which will require an informative screening method. This review described the etiology and early pathogenesis of TGCT, as well as the possibilities of early detection and future potential of screening men at risk for TGCT. For screening, a well-defined risk profile based on both genetic and environmental risk factors is needed. Since 2009, several genome wide association studies (GWAS) have been published, reporting on single-nucleotide polymorphisms (SNPs) with significant associations in or near the genes KITLG, SPRY4, BAK1, DMRT1, TERT, ATF7IP, HPGDS, MAD1L1, RFWD3, TEX14, and PPM1E, likely to be related to TGCT development. Prenatal, perinatal, and postnatal environmental factors also influence the onset of CIS. A noninvasive early detection method for CIS would be highly beneficial in a clinical setting, for which specific miRNA detection in semen seems to be very promising. Further research is needed to develop a well-defined TGCT risk profile, based on gene-environment interactions, combined with noninvasive detection method for CIS.

Abstract
Purpose To analyze the differences of semen parameters in Korean young population for three periods from 2002 to 2013. Materials and Methods A total of 516 semen samples were collected from Korean men presenting for infertility, varicoceles or other infectious problems for three periods from 2002 to 2012: January 2002-December 2003, January 2007-December 2008, and January 2012-December 2013. A standard World Health Organization procedure for semen analysis was performed for assessment of semen concentration, volume, motility, morphology, and pH. Results A total of 160, 162, 194 men constituted the study populations in 2002 to 2003, in 2007 to 2008, and in 2012 to 2013, respectively. The overall sperm parameter results suggested a statistically significant difference between 2002 to 2003 and 2012 to 2013 except pH. However, considering the data from 2007 to 2008, there were no trends in changes in overall semen parameters. Negative correlations were observed in all semen parameters with increasing age in all patients, except for pH. In addition, semen volume, motility, and morphology had higher negative correlation coefficients with age, from 2002 to 2013, serially. Conclusions There were no significant changes in the semen parameters of Korean men from 2002 to 2013. In addition, semen volume, motility, and morphology showed higher negative correlation coefficients with age from 2002 to 2013, serially.

Hyperemesis gravidarum and risk of cancer in offspring, a Scandinavian registry-based nested case-control study. BMC Cancer 2015; 15:398. [PMID: 25963309 PMCID: PMC4430929 DOI: 10.1186/s12885-015-1425-4] [Citation(s) in RCA: 8] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/06/2014] [Accepted: 05/06/2015] [Indexed: 12/21/2022] Open
Abstract
BACKGROUND Hyperemesis gravidarum is a serious condition affecting 0.8-2.3% of pregnant women and can be regarded as a restricted period of famine. Research concerning potential long-term consequences of the condition for the offspring, is limited, but lack of nutrition in-utero has been associated with chronic disease in adulthood, including some cancers. There is growing evidence that several forms of cancer may originate during fetal life. We conducted a large study linking the high-quality population-based medical birth- and cancer registries in Norway, Sweden and Denmark, to explore whether hyperemesis is associated with increased cancer risk in offspring. METHODS A registry-based nested case-control study. Twelve types of childhood cancer were selected; leukemia, lymphoma, cancer of the central nervous system, testis, bone, ovary, breast, adrenal and thyroid gland, nephroblastoma, hepatoblastoma and retinoblastoma. Conditional logistic regression models were applied to study associations between hyperemesis and risk of childhood cancer, both all types combined and separately. Cancer types with five or more exposed cases were stratified by age at diagnosis. All analysis were adjusted for maternal age, ethnicity and smoking, in addition to the offspring's Apgar score, placental weight and birth weight. Relative risks with 95% confidence intervals were calculated. RESULTS In total 14,805 cases and approximately ten controls matched on time, country of birth, sex and year of birth per case (147,709) were identified. None of the cancer types, analyzed combined or separately, revealed significant association with hyperemesis. When stratified according to age at diagnosis, we observed a RR 2.13 for lymphoma among adolescents aged 11-20 years ((95% CI 1.14-3.99), after adjustment for maternal ethnicity and maternal age, RR 2.08 (95% CI 1.11-3.90)). The finding was not apparent when a stricter level of statistical significance was applied. CONCLUSIONS The main finding of this paper is that hyperemesis does not seem to increase cancer risk in offspring. The positive association to lymphoma may be by chance and needs confirmation.

Abstract
OBJECTIVE The purpose of this study is to determine the frequency of emotional, behavioral, and learning disorders in children exposed in utero to hyperemesis gravidarum (HG) and to identify prognostic factors for these disorders. STUDY DESIGN Neurodevelopmental outcomes of 312 children from 203 mothers with HG were compared to neurodevelopmental outcomes from 169 children from 89 unaffected mothers. Then the clinical profiles of patients with HG and a normal child outcome were compared to the clinical profiles of patients with HG and a child with neurodevelopmental delay to identify prognostic factors. Binary responses were analyzed using either a Chi-square or Fisher Exact test and continuous responses were analyzed using a t-test. RESULTS Children exposed in utero to HG have a 3.28-fold increase in odds of a neurodevelopmental diagnosis including attention disorders, learning delay, sensory disorders, and speech and language delay (P<0.0005). Among characteristics of HG pregnancies, only early onset of symptoms (prior to 5 weeks gestation) was significantly linked to neurodevelopmental delay. We found no evidence for increased risk of 13 emotional, behavioral, and learning disorders, including autism, intellectual impairment, and obsessive-compulsive disorder. However, the study was not sufficiently powered to detect rare conditions. Medications, treatments, and preterm birth were not associated with an increased risk for neurodevelopmental delay. CONCLUSION Women with HG are at a significantly increased risk of having a child with neurodevelopmental delay. Common antiemetic treatments were not linked to neurodevelopmental delay, but early symptoms may play a role. There is an urgent need to address whether aggressive treatment that includes vitamin and nutrient supplementation in women with early symptoms of severe nausea of pregnancy decreases the risk of neurodevelopmental delay.

Abstract
Reproductive toxicities and endocrine disruptions caused by chemicals in adult males are still poorly understood. It is our objectives to understand further details of the initial adverse effects leading severe testicular toxicities of a pharmaceutical endocrine disruptor, diethylstilbestrol (DES). Downregulations of both testicular regulatory proteins, such as the steroidogenic acute regulatory protein (StAR) and the peripheral benzodiazepine receptor (PBR), which play important roles in the transport of cholesterol into the mitochondria, and cytochrome P450 mediating the cholesterol side chain cleavage reaction (P450scc), were observed in the rat orally administered DES (340 μg/kg/2 days) for 2 weeks. We found that after only 1 week treatment with DES, the blood and testicular testosterone (TS) levels were drastically decreased without abnormalities of the StAR and PBR; however, the protein and mRNA levels of P450scc were diminished. Decrease in the conversion rate of cholesterol to pregnenolone was delayed in the in vitro assay using the testicular mitochondrial fraction from the rat treated with DES for 1 week. When the precursors in TS biosynthesis containing the testis were identified and determined by liquid chromatography-mass spectrometry analysis, decreased levels of all precursors except cholesterol were observed. In conclusion, suppressed cytochrome P450scc expression in adult male rat was identified as an initial target of DES in testicular steroidogenesis disorder leading reproductive toxicities.

Abstract
Maternal cigarette smoking may affect the intrauterine hormonal environment during pregnancy and this early fetal exposure may have detrimental effects on the future trajectory of reproductive health. In this review, we discuss the epidemiological literature on the association between prenatal exposure to maternal cigarette smoking and several aspects of reproductive health. The literature points towards an increased risk of the urogenital malformation cryptorchidism, but a potential protective effect on the risk of hypospadias in sons following prenatal cigarette smoking exposure. Studies on sexual maturation find a tendency towards accelerated pubertal development in exposed boys and girls. In adult life, prenatally exposed men have impaired semen quality compared with unexposed individuals, but an influence on fecundability, that is, the biological ability to reproduce, is less evident. We found no evidence to support an association between prenatal cigarette smoking exposure and testicular cancer. Among adult daughters, research is sparse and inconsistent, but exposure to cigarette smoking in utero may decrease fecundability. In conclusion, prenatal exposure to cigarette smoking may cause some long-term adverse effects on the reproductive health.

Abstract
OBJECTIVE To investigate the consequences of weight loss in pregnancy on pregnancy outcomes and cardiometabolic profile in childhood. DESIGN Prospective birth cohort (ABCD study). SETTING Between 2003 and 2004, all pregnant women in Amsterdam were approached for study participation. POPULATION 7818 pregnant women were included, of which 3165 consented to having their children examined at 5-6 years of age. In 1956 children fasting capillary blood samples were also taken. METHODS At antenatal booking, women answered questions about their pregnancy and whether they suffered from severe weight loss (SWL; >5 kg). Pregnancy details and outcomes were available through the obstetric caregiver. MAIN OUTCOME MEASURES At birth main outcome measures were prematurity (<37 weeks) and birthweight. At follow-up, body mass index (BMI), blood pressure, glucose and lipids were assessed. RESULTS SWL occurred in 6.8% of cases. Women with SWL had similar preterm birth rates compared with women without these complaints (adjusted OR 1.1, 95%CI 0.7, 1.7). Birthweight (adjusted difference - 31 g, 95%CI -76, 15) and BMI at 5-6 years of age (adjusted difference 0.2 kg/m(2) , 95%CI 0.0, 0.5) were similar in children born to mothers with SWL and without SWL, but blood pressure was increased. For diastolic blood pressure this association was independent of confounders (adjusted difference 1.4 mmHg, 95%CI 0.4, 2.4). Lipid and glucose levels were not significantly different between these groups. CONCLUSION Early pregnancy weight loss, usually occurring as a manifestation of hyperemesis gravidarum, could have long-term consequences for offspring health.

Abstract
Nausea and vomiting of pregnancy is a very common occurrence, but the reported incidence of hyperemesis gravidarum (a more severe form of vomiting in pregnancy) is much lower, estimated to vary from 0.3-3.6%. Studies have shown that nausea and vomiting of pregnancy is associated with improved fetal outcomes, such as lower rates of miscarriage. However, there are limited data on outcomes associated with hyperemesis gravidarum, which have focused on pregnancy and neonatal outcomes. Recently, studies showed adverse health outcomes, such as a reduction in insulin sensitivity in childhood and increased incidence of psychological disorders in adulthood. The effects of hyperemesis gravidarum in the offspring need to be further examined throughout childhood, adolescence, and into adulthood, so that long-term disease risks can be evaluated.

Abstract
Data from animal models, historical cohorts, and modern epidemiologic studies have suggested that maternal characteristics can affect reproductive health of offspring; however, distinguishing between prenatal and postnatal contributions is difficult. Anogenital distance (AGD), the distance from the anus to the genitals, is believed to be a biomarker of prenatal androgen exposure in many species, and in humans it has been associated with several adult reproductive health outcomes. We used data from a pregnancy cohort study conducted in 4 US cities from 1999-2005 to examine whether AGD measurements in infants were associated with maternal self-reported age at conception, age at menarche, age at first birth, parity, and gravidity. AGD was measured in 289 infants (140 male, 149 female) born to study participants. After adjustment for relevant covariates, in linear regression models stratified by infant sex, maternal age was positively associated with AGD in male infants (AGD, anus to penis: β = 0.50, P = 0.002; AGD, anus to scrotum: β = 0.29, P = 0.02) but not female infants. Parity was inversely associated with AGD (anus to scrotum; β = -1.68, P = 0.03) in male infants. No other maternal characteristic predicted AGD in either sex. The mechanism underlying the unexpected relationship between maternal characteristics and AGD is unknown; however, we suggest several possibilities for future study.

Abstract
OBJECTIVE This study aimed to share our experience with tumors of undescended testis (UDT) and to assess the impact of primary cisplatin-based chemotherapy on such tumors. MATERIALS AND METHODS This study included the cases of tumor in UDT from February 2005 to December 2011. Evaluation of the cases was done with proper clinical examination and laboratory investigations along with tumor markers (alfa-feto protein, beta-human chorionic gonadotropin, lactate dehydrogenase) and contrast-enhanced computed tomography abdomen. Fine needle aspiration cytologywas done in all cases. Primary chemotherapy with three cycles of bleomycin, etoposide, and cisplatin regimen at three weekly intervals started in all cases. Response to treatment was seen after four weeks of the third cycle. RESULTS Fourteen cases (12.5%) of germ cell tumor in UDT out of 112 cases of germ cell tumor of the testis were included. The age ranged from 16-60 years. Histological diagnosis was pure seminoma in all cases. After three cycles of BEP regime, complete response was seen in 11 cases and partial response in three cases where the residual tumor was excised along with retroperitoneal lymph node dissection RPLND. Of the 14 cases, 13 were in regular follow-up and one was lost to follow-up. All on follow-up were doing well without recurrence till now. CONCLUSION Surgical removal of the primary tumor in UDT with or without bulky metastasis is complicated. Primary chemotherapy with cisplatin-based regimen is a good option in such cases.

BACKGROUND Research on early life exposures and testicular germ cell tumors (TGCT) risk has focused on a possible perinatal etiology with a well-known hypothesis suggesting that hormonal involvement during fetal life is associated with risk. Second-to-fourth digit ratio (2D:4D) and left-hand dominance have been proposed as markers of prenatal hormone exposure. AIM To evaluate associations between 2D:4D digit ratio, right minus left 2D:4D (ΔR-L), and left-hand dominance and TGCT in the U.S. Servicemen's Testicular Tumor Environmental and Endocrine Determinants Study. METHODS A total of 246 TGCT cases and 236 non-testicular cancer controls participated in the current study, and completed a self-administered questionnaire. Associations between digit ratio, hand dominance and TGCT were estimated using unconditional logistic regression adjusting for identified covariates. RESULTS Right 2D:4D was not associated with TGCT [odds ratio (OR) for a one-standard deviation (SD) increase in right-hand 2D:4D: 1.12, 95% confidence interval (CI): 0.93-1.34]. The results were consistent when evaluating the association based on the left hand. The difference between right and left-hand 2D:4D was also not associated with TGCT risk [OR for a one-SD increase in ΔR-L: 1.03, 95% CI: 0.87-1.23]. Compared to men who reported right-hand dominance, ambidexterity [OR (95% CI)=0.65 (0.30-1.41)] and left-hand dominance [OR (95% CI)=0.79 (0.44-1.44)] were not associated with risk. CONCLUSIONS These results do not support the hypothesis that prenatal hormonal imbalance is associated with TGCT risk. Given the limited sample size, further evaluation of the relationship between TGCT and prenatal hormonal factors using digit ratio, ΔR-L, or left-hand dominance and larger sample size are warranted.

Abstract
Background Valid registration of medical information is essential for the quality of registry-based research. Hyperemesis gravidarum (HG) is characterized by severe nausea and vomiting, weight loss and electrolyte imbalance starting before 22nd gestational week. Given the fact that HG is a generally understudied disease which might have short- and long- term health consequences for mother and child, it is of importance to know whether potential misclassification bias influences the results of future studies. We therefore assessed the validity of the HG-registration in the in Medical Birth Registry of Norway (MBRN) using hospital records. Methods The sample comprised all women registered in MBRN with HG and who delivered at Ullevål and Akershus hospitals in 1.1.-31.3.1970, 1.4.-30.6.1986, 1.7.-30.9.1997 and 1.10.-31.12.2001. A random sample of 10 women per HG case, without HG according to MBRN, but who delivered during the same time periods at the same hospitals was also collected. The final sample included 551 women. Sensitivity, specificity, positive and negative predictive values (PPV and NPV) were estimated using strict and less strict diagnostic criteria of HG, indicating severe and mild HG, respectively. Hospital journals were used as gold standard. Results Using less strict diagnostic criteria of HG, sensitivity, specificity, PPV and NPV were 83.9% (95% CI: 67.4-92.9), 96.0% (95% CI: 93.9-97.3), 55.3% (95% CI: 41.2-68.6) and 99.0% (95% CI: 97.7-99.6), respectively. For strict diagnostic criteria, being hospitalised due to HG the corresponding values were 64% (95% CI: 38.8-87.2), 92% (95% CI: 90.2-94.6), 18.6% (95% CI: 10.2-31.9) and 99.0% (95% CI: 97.7-99.6). Conclusions The results from our study are comparable to previous research on disease registration in MBRN, and show that MBRN can be considered valid for mild HG but not for severe HG.

Abstract
Large discrepancy remains for the hormone-responsible cancers with regards to the conditions generating the optimal opportunity for cancerogenesis. In the research, altered steroid profiles were observed in patients with urogenital tract cancer diseases, namely bladder, kidney, prostate and testis ones. The presented steroid profiles from 154 subjects, including 77 urogenital tract cancer patient and 77 healthy controls were determined by liquid chromatography coupled to mass spectrometry method. Because the original experimental data obtained as a result of analytical experiment in order to interpret them in better way required the appropriate pre-treatment, the data were standardized by scaling and centering. In order to determine which samples form a collection for a high-capacity predictive model, Kennard-Stone's algorithm was used. A principal component analysis of preprocessed data provided better consistency of the steroid profiles with health status of subjects than PCA profiles without data preprocessing and showed a tendency to separate clusters of cancer patients from healthy subjects. The discriminant analysis was also performed and the percent of correct classification of cancer patients and control group was calculated. Finally, detailed studies examined the role of steroid profiles measured in urine, and considered as potential biomarkers related to urogenital cancer and associated renal dysfunctions.

Abstract
Background: Similarities between the age-specific incidence pattern of testicular germ cell tumours (TGCTs) and the age-specific incidence pattern of cancers of viral origin prompted us to evaluate the relationship between common infections occurring during childhood or young adult life and TGCT using existing data from the US Servicemen's Testicular Tumor Environmental and Endocrine Determinants (STEED) case–control study. Methods: TGCT cases diagnosed between 2002 and 2005 (n=767) were matched on age, race and serum draw date to at least one control (n=929). Results: None of the infections evaluated were associated with TGCT risk. Further, a meta-analysis of mumps and mumps orchitis or orchitis infection did not support an association with TGCT (mumps pooled odds ratio (OR): 1.03, 95% confidence interval (CI): 0.89–1.20; mumps orchitis or orchitis pooled OR: 1.80, 95% CI: 0.74–4.42). Conclusion: Based on our evaluation of childhood and early life infections and meta-analyses of mumps and mumps orchitis and/or orchitis, TGCT does not appear to be associated with common childhood infections.

Abstract
INTRODUCTION Risk of testicular germ cell tumors (TGCT) is consistently associated with a history of cryptorchidism (CO) in epidemiologic studies. Factors modifying the association may provide insights regarding etiology of TGCT and suggest a basis for individualized care of CO. To identify modifiers of the CO-TGCT association, we conducted a comprehensive, quantitative evaluation of epidemiologic data. MATERIALS AND METHODS Human studies cited in PubMed or ISI Web of Science indices through December 2011 and selected unpublished epidemiologic data were reviewed to identify 35 articles and one unpublished dataset with high-quality data on the CO-TGCT association. Association data were extracted as point and 95% confidence interval estimates of odds ratio (OR) or standardized incidence ratio (SIR), or as tabulated data. Values were recorded for each study population, and for subgroups defined by features of study design, CO and TGCT. Extracted data were used to estimate summary risk ratios (sRR) and evaluate heterogeneity of the CO-TGCT association between subgroups. RESULTS The overall meta-analysis showed that history of CO is associated with four-fold increased TGCT risk [RR = 4.1(95% CI = 3.6-4.7)]. Subgroup analyses identified five determinants of stronger association: bilateral CO, unilateral CO ipsilateral to TGCT, delayed CO treatment, TGCT diagnosed before 1970, and seminoma histology. CONCLUSIONS Modifying factors may provide insight into TGCT etiology and suggest improved approaches to managing CO. Based on available data, CO patients and their parents or caregivers should be made aware of elevated TGCT risk following orchidopexy, regardless of age at repair, unilateral vs. bilateral non-descent, or position of undescended testes.
