Mirroring Perinatal Outcomes in a Romanian Adolescent Cohort of Pregnant Women from 2015 to 2021.

Although the rates of adolescent pregnancies appear to have dropped according to the World Health Organization (WHO), the decrease in the age of the first menarche and better nutrition seems to contribute to the otherwise high rate of adolescent pregnancy worldwide, despite the efforts of different organizations to improve upon this trend. We conducted a population-based retrospective cohort study from January 2015 to December 2021 using our hospitals' database. We totaled 2.954 adolescent and 6.802 adult pregnancies. First, we compared younger adolescents' outcomes with those of older adolescents, as well as with adolescents aged between 18 and 19 years old; secondly, we compared adolescent pregnancies with adult ones. We detected higher percentages of cephalo-pelvic disproportion (43.2%), cervical dystocia (20.7%), and twin pregnancy (2.7%) in underage adolescents compared with 32%, 14.1%, and 1% in older underage adolescents, respectively, and 15.3%, 3.1%, and 0.6% in older ones. As teens became older, the likelihood of malpresentations and previous C-sections rose, whereas the likelihood of vaginal lacerations declined. When comparing adolescents with adult women, we found more cases that required episiotomy (48.1% compared with 34.6%), instrumental delivery (2.1% compared with 1%), and cervical laceration (10.7% compared with 8.4%) in the adolescent group, but the rates of malpresentation (11.4% compared with 13.5%), previous C-section (13.9% compared with 17.7%), and placenta and vasa praevia (4.5.6% compared with 14%) were higher in the adult women group. Adolescent pregnancy is prone to being associated with higher risks and complications and continues to represent a challenge for our medical system.

Hormonal, apoptotic, proliferative and inflammatory markers' expression in Desogestrel-treated women with ovarian endometriosis.

Endometriosis is a relatively frequent pathology in gynecological practice. We performed an analysis to demonstrate the molecular changes that occur in endometriosis synthetic progestin-treated patients, hoping to sketch a possible pathophysiological pathway that will help us to better understand and treat this debilitating disease. We conducted a prospective study that included a group of 40 women, evaluated in our hospital between 2020-2021. We evaluated immunohistochemical tissue expression of estrogen receptor (ER), progesterone receptor (PR), B-cell lymphoma 2 (Bcl-2) protein, Ki-67, and serum levels of osteopontin (OPN) and vascular endothelial growth factor (VEGF) in patients with ovarian endometrioma with and without progestin treatment. Our study revealed that Desogestrel treatment increases OPN serum levels, PR and Bcl-2 tissue expression and reduces VEGF serum levels and Ki-67 tissue expression. The results we have obtained are very interesting because the serum levels of OPN seem to be more influenced by progestin treatment, than by endometriosis itself. The study we have conducted gives a molecular complex view of what endometriosis represents and on how Desogestrel treatment works.

Research on myoma in Northeastern Romania and socio-medical outcomes.

Myomas are the most common benign uterine tumors in women of childbearing age, with an incidence of up to 77% and a major impact on women's health. The aim of our study was to provide information concerning the incidence and prevalence of myomas in the patients admitted to a tertiary referral center in Northeastern Romania. This retrospective study conducted at the Iasi 'Cuza Voda' University Hospital of Obstetrics and Gynecology (Romania) included 11,538 patients, representing all patients admitted to the gynecology department between January 2013 and December 2019. During the study interval, the number of hysterectomies (total and for myomas) had increased. The rate of laparoscopic surgery showed a small decrease (31.3% from 34%), classic therapy showed a decrease by more than 10% and the hysteroscopy rate was tripled. There are few studies in the literature that have established with accuracy the incidence of myomas. In the present study, the prevalence of hysterectomy for myomas was 54.42%. Our results are in agreement with the data in the literature, namely that 40-60% of all performed hysterectomies are for myomas. The vast majority of admissions for myomas involve a surgical procedure most commonly hysterectomy.

Genital infection with Ureaplasma urealyticum and its effect on pregnancy.

Chorioamnionitis or intra-amniotic infection is an infection that affects the intrauterine content during pregnancy. Numerous studies have reported vaginal colonization with various types of infectious agents as a risk factor for chorioamnionitis. Although this complication occurs due to the ascending polymicrobial bacterial infection at the time of membrane breakage, it may also occur in pregnant women with intact membranes, mainly due to Ureaplasma urealyticum (U. urealyticum) and Mycoplasma hominis (M. hominis). The main aim of the present study was to identify a region-specific panel of infectious agents that can be used more accurately determine premature birth, as well as the premature rupture of membranes (PROM). Thus, a 10-year retrospective study was conducted. A total of 1,301 pregnant women with PROM and premature birth or spontaneous abortion were included in the study. It was observed that the main infectious agent varied in the five groups analyzed in total. The infectious agent distribution also varied depending on environmental parameters. Ureaplasma was found to be the most frequently detected germ amongst the infectious agents of the vaginal cultures from pregnant women enrolled in the present study, regardless of gestational age. On the whole, the findings of the present study suggest that additional studies are required, in order to confirm that diagnosis and treatment according to laboratory results of vaginal infections with U. urealyticum/M. hominis during the first trimester of pregnancy could prevent premature birth, abortion or chorioamnionitis.

A Romanian study on the impact of glypressin in laparoscopic myomectomy.

A major myomectomy-associated problem is excessive blood loss. The aim of the present study was to evaluate the effect of glypressin on blood loss during laparoscopic myomectomy (LM) in women with uterine myomas. A total of 188 women scheduled for LM for uterine myomas were divided into two groups. The one group of women (n=64) received a 5-ml intramyometrial injection of glypressin 0.2 mg/ml (glypressin group; group 1). The other group of women (n=124) (group 2) had an LM performed without any other method to reduce blood loss. The decrease in postoperative hemoglobin (Hb), hematocrit (Ht), morbidity and duration of hospital stay were assessed. The results revealed that Hb and Ht (as it was presumed) exhibited similar changes in our study. Statistically significant differences (P<0.05) were obtained between the two groups in terms of Hb and Ht; after LM both Hb and Ht were decreased. In conclusion, the impact of glypressin administration in hemorrhage control in uterine leiomyomas may establish new future perspectives, regarding its administration in gynecological hemorrhagic pathologies.

Phthalate Exposure from Drinking Water in Romanian Adolescents.

Phthalates are plastic softeners that have been linked to several adverse health outcomes. The relative contributions of different sources to phthalate exposure in populations in different regions and at different life stages is unclear. We examined the relationships between water consumption, consumer product use, and phthalate exposure among 40 adolescents (20 males, 20 females) in Cluj-Napoca, Romania. Interviewers administered a questionnaire about drinking water consumption and use of phthalate-containing consumer products. Four common phthalates were measured in representative samples of participants' municipal drinking water and consumed bottled water using gas chromatography-mass spectrometry. Urine samples were collected from participants and analyzed for the corresponding phthalate metabolites. Relationships between different exposure measures were assessed using nonparametric tests (Spearman rank correlation coefficients and the Kruskal⁻Wallis test). Diisobutyl phthalate, dibutyl phthalate, and bis(2-ethylhexyl) phthalate were commonly detected in bottled water, but generally not the municipal drinking water samples. Mono-n-butyl phthalate (MnBP) was the most commonly detected urinary metabolite (detected in 92.5% of participants) and had the highest maximum concentration (1139.77 µg/g creatinine). We did not identify any statistically significant associations between water consumption or consumer product use practices and urinary phthalate metabolite concentrations in our adolescent group, and directions of correlation coefficients differed by individual phthalate compound. While phthalate exposure was widespread, these results highlight the challenges in examining phthalate exposure determinants and emphasize the need for further investigation into understanding exposure sources and potential health risks from chronic low-level exposures.

Impact of exposure to tobacco smoke, arsenic, and phthalates on locally advanced cervical cancer treatment-preliminary results.

BACKGROUND: Cancer research is a national and international priority, with the efficiency and effectiveness of current anti-tumor therapies being one of the major challenges with which physicians are faced. OBJECTIVE: To assess the impact of exposure to tobacco smoke, arsenic, and phthalates on cervical cancer treatment. METHODS: We investigated 37 patients with locally advanced cervical carcinoma who underwent chemotherapy and radiotherapy. We determined cotinine and five phthalate metabolites in urine samples collected prior to cancer treatment, by gas chromatography coupled to mass spectrometry, and urinary total arsenic by atomic absorption spectrometry with hydride generation. We used linear regression to evaluate the effects of cotinine, arsenic, and phthalates on the change in tumor size after treatment, adjusted for confounding variables. RESULTS: We detected no significant associations between urinary cotinine, arsenic, or phthalate monoesters on change in tumor size after treatment, adjusted for urine creatinine, age, baseline tumor size, and cotinine (for arsenic and phthalates). However, higher %mono-ethylhexyl phthalate (%MEHP), a putative indicator of phthalate diester metabolism, was associated with a larger change in tumor size (ß = 0.015, 95% CI [0.003-0.03], P = 0.019). CONCLUSION: We found no statistically significant association between the urinary levels of arsenic, cotinine, and phthalates metabolites and the response to cervical cancer treatment as measured by the change in tumor size. Still, our results suggested that phthalates metabolism may be associated with response to treatment for locally advanced cervical cancer. However, these observations are preliminary and will require confirmation in a larger, more definitive investigation.

Mercury analysis in hair: Comparability and quality assessment within the transnational COPHES/DEMOCOPHES project.

Human biomonitoring (HBM) is an effective tool for assessing actual exposure to chemicals that takes into account all routes of intake. Although hair analysis is considered to be an optimal biomarker for assessing mercury exposure, the lack of harmonization as regards sampling and analytical procedures has often limited the comparison of data at national and international level. The European-funded projects COPHES and DEMOCOPHES developed and tested a harmonized European approach to Human Biomonitoring in response to the European Environment and Health Action Plan. Herein we describe the quality assurance program (QAP) for assessing mercury levels in hair samples from more than 1800 mother-child pairs recruited in 17 European countries. To ensure the comparability of the results, standard operating procedures (SOPs) for sampling and for mercury analysis were drafted and distributed to participating laboratories. Training sessions were organized for field workers and four external quality-assessment exercises (ICI/EQUAS), followed by the corresponding web conferences, were organized between March 2011 and February 2012. ICI/EQUAS used native hair samples at two mercury concentration ranges (0.20-0.71 and 0.80-1.63) per exercise. The results revealed relative standard deviations of 7.87-13.55% and 4.04-11.31% for the low and high mercury concentration ranges, respectively. A total of 16 out of 18 participating laboratories the QAP requirements and were allowed to analyze samples from the DEMOCOPHES pilot study. Web conferences after each ICI/EQUAS revealed this to be a new and effective tool for improving analytical performance and increasing capacity building. The procedure developed and tested in COPHES/DEMOCOPHES would be optimal for application on a global scale as regards implementation of the Minamata Convention on Mercury.

The European COPHES/DEMOCOPHES project: towards transnational comparability and reliability of human biomonitoring results.

COPHES/DEMOCOPHES has its origins in the European Environment and Health Action Plan of 2004 to "develop a coherent approach on human biomonitoring (HBM) in Europe". Within this twin-project it was targeted to collect specimens from 120 mother-child-pairs in each of the 17 participating European countries. These specimens were investigated for six biomarkers (mercury in hair; creatinine, cotinine, cadmium, phthalate metabolites and bisphenol A in urine). The results for mercury in hair are described in a separate paper. Each participating member state was requested to contract laboratories, for capacity building reasons ideally within its borders, carrying out the chemical analyses. To ensure comparability of analytical data a Quality Assurance Unit (QAU) was established which provided the participating laboratories with standard operating procedures (SOP) and with control material. This material was specially prepared from native, non-spiked, pooled urine samples and was tested for homogeneity and stability. Four external quality assessment exercises were carried out. Highly esteemed laboratories from all over the world served as reference laboratories. Web conferences after each external quality assessment exercise functioned as a new and effective tool to improve analytical performance, to build capacity and to educate less experienced laboratories. Of the 38 laboratories participating in the quality assurance exercises 14 laboratories qualified for cadmium, 14 for creatinine, 9 for cotinine, 7 for phthalate metabolites and 5 for bisphenol A in urine. In the last of the four external quality assessment exercises the laboratories that qualified for DEMOCOPHES performed the determinations in urine with relative standard deviations (low/high concentration) of 18.0/2.1% for cotinine, 14.8/5.1% for cadmium, 4.7/3.4% for creatinine. Relative standard deviations for the newly emerging biomarkers were higher, with values between 13.5 and 20.5% for bisphenol A and between 18.9 and 45.3% for the phthalate metabolites. Plausibility control of the HBM results of all participating countries disclosed analytical shortcomings in the determination of Cd when using certain ICP/MS methods. Results were corrected by reanalyzes. The COPHES/DEMOCOPHES project for the first time succeeded in performing a harmonized pan-European HBM project. All data raised have to be regarded as utmost reliable according to the highest international state of the art, since highly renowned laboratories functioned as reference laboratories. The procedure described here, that has shown its success, can be used as a blueprint for future transnational, multicentre HBM projects.

Management of borderline ovarian tumors.

UNLABELLED: Borderline ovarian tumors are an intermediate stage between benign cystadenomas and adenocarcinomas. AIM: The paper evaluates the management of borderline ovarian tumors (BOTs) in the patients admitted and treated in our clinic in the interval January 2003 - June 2011. MATERIAL AND METHODS: The observation sheets and pathology results of 264 patients with malignant ovarian tumors were analyzed. RESULTS: Of the 264 malignant ovarian tumors 74 (28.03%) were low malignant potential. Patients with BOT were aged 18-72 years (mean 46 +/- 6.2 years) and those with invasive tumors 14-83 years (mean 53 +/- 9.8 years). 92.18% were in stage 1. Sixty tumors were graded G1. 53.52 % of the tumors were over 10 cm (maximum 30 cm) in size. The histological types were: serous - 35 cases, mucinous - 19 cases, mixed (serous and mucinous) - 8 cases, and endometrioid - 2 cases. Fifteen patients presented intraepithelial carcinoma and 11 noninvasive implants into the peritoneal cavity. Five women had recurrences. CONCLUSIONS: Ovarian borderline tumors with histological characteristics of carcinoma, but with good behavior are now with better defined histological features. The biggest challenge in the management of women with these tumors is to identify the subset that will behave in a malignant fashion and to develop effective treatment for them.

[Agnogenic myeloid metaplasia in pregnancy. Case report]. / Metaplazia mieloida agnogenica si sarcina. Prezentare de caz.

UNLABELLED: Idiopathic myelofibrosis is a rare myeloproliferative disorder characterized by excessive accumulation of connective tissue in the bone marrow in association with anemia, splenomegaly and extramedullary hematopoiesis. A rare case of pregnancy in a patient with agnogenic myeloid metaplasia who carried a term pregnancy is described. In spite of the increased perinatal risks, a favorable outcome was possible with close antepartum surveillance. CONCLUSION: Idiopathic myelofibrosis was once thought to be a contraindication to pregnancy. With careful management, successful pregnancies can be achieved.

Interferometric method for birefringence determination with a polarizing microscope.

We present a new mathematical technique which can be used to determine the main refractive indices and the birefringence of an anisotropic layer by using a polarizing microscope in conoscopic illumination. The values of the birefringence for the yellow radiation of a Na lamp are determined here for a Carpathian quartz sample, but the technique can also be applied to the study of other uniaxial substances such as liquid crystals, model membranes or biological tissues. The validity of the proposed method was tested by comparing the results with those obtained with a Rayleigh interferometer and by using the technology of channeled spectra.

[The management of unexplained recurrent abortions. Is immunotherapy an option?]. / Managementul avorturilor recurente de cauza neprecizata. Este imunoterapia o optiune?

Recurrent abortions, defined as more than three consecutive pregnancy losses, are associated with genetic, anatomic and endocrine causes. Whenever investigations fail to detect a cause, immunological dysfunctions are incriminated. The paper shortly reviews the main causes, investigation protocols and immune therapeutic attempts that have been made. Active immunization with allogenic leukocytes or trophoblastic membranes, passive immunization with intravenous immunoglobulins and immunomodulation with glucocorticoids in unexplained recurrent abortions generated contradictory results and was banned by reproductive immunology scientists as empirical, risky for the mother and harmful for the fetus. Confronted with desperate couples, clinicians use the immunotherapy with paternal lymphocytes or intravenous immunoglobulins in healthy women with unexplained recurrent abortions or in cases where accepted therapies failed.
