RESUMEN

OBJECTIVES: Elastography is considered a novel technique in the assessment of placenta parenchymal elasticity and very few data present the feasibility of elastography on human fetal tissue. This study aims to investigate the feasibility of fetal liver and placenta elastography and differences in pregnancies with GDM. METHODS: Fifty-five women with GDM and 40 women with uncomplicated pregnancy as the control group was enrolled prospectively in this case-control study. Fetal liver VTIQ and placenta VTIQ elastography were performed between 25 and 39 weeks of pregnancy. RESULTS: Mean placenta thickness at the level of umbilical cord insertion was significantly higher in the GDM group than in the control group (p=0.034). VTIQ elastography elasticity velocity (kPa) examinations revealed similar mean placenta and mean fetal liver stiffness in both groups. A weak to moderate correlation was observed between the mean elasticity of the placenta and the mean elasticity of the fetal liver (r=0.310; p=0.004). CONCLUSIONS: Elastography may provide valuable information of especially on fetal tissue development and pathology. While placenta and fetal liver VTIQ elastography are feasible in pregnancy, the diagnostic value of these examinations in GDM is not certain and it seems to be that significant differences in SWE examinations that reflect structural changes in fetal tissue or placenta are more prominent in more chronic conditions such as type 1 and type 2 diabetes mellitus.

RESUMEN

Objective: In the present study, we investigated the expression of CD56, ADAM17 and FGF21 antibodies (Ab), which we think have an effect on the pathophysiology of preeclampsia (PE), in pregnant patients with healthy placentas and placentas with PE. The expression of these antibodies has been investigated in a limited amount of former research, but their role in PE has not yet been clarified. With this study, we aimed to contribute to the elucidation of the pathophysiology of PE and the detection of new target molecules for treatment. Materials and Methods: Parturients with singleton pregnancy at 32 weeks or above without any maternal or fetal pathology who were admitted to the Department of Obstetrics and Gynecology, Zonguldak Bülent Ecevit University Practice and Research Hospital between 11 January 2020 and 7 January 2022 were included in the present study. Pregnant women with coexisting disease or a pathology related to the placenta (ablation placenta, vasa previa, hemangioma, etc.) were excluded. CD56, ADAM17 and FGF21 antibodies were histopathologically and immunohistochemically detected in 60 placentas with PE (study group) and 43 healthy placentas (control group). Results: CD56, ADAM17 and FGF21 proteins were all more intensely expressed in preeclamptic placentas and a statistically significant difference was found between the two groups for all three antibodies (p < 0.001). Deciduitis, perivillous fibrin deposition, intervillous fibrin, intervillous hemorrhage, infarct, calcification, laminar necrosis and syncytial node were found to be significantly more common in the study group (p < 0.001). Conclusions: We observed that CD56, ADAM17 and FGF21 expressions increased in preeclamptic placentas. These Ab may be responsible for the pathogenesis of PE, which can be illuminated with further studies.

RESUMEN

This study aimed to report a case of mild novel coronavirus disease (COVID-19) in a pregnant woman with probable viremia, as reverse transcription-polymerase chain reaction (RT-PCR) testing of endometrial and placental swabs for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) was positive. A 26-year-old multigravida at 35 weeks 2 days of gestation, who had extensive thigh and abdominal cellulitis, tested SARS-CoV-2 positive by RT-PCR performed on samples from the endometrium and maternal side of the placenta. However, other samples (amniotic fluid, fetal side of the placenta, umbilical cord, maternal vagina, and neonatal nasopharynx) tested negative for SARS-CoV-2. This is one of the rare reports of probable SARS-CoV-2 viremia with the presence of SARS-CoV-2 in the endometrium and placenta, but not leading to vertical transmission and neonatal infection. Because knowledge about transplacental transmission and results is very limited, we conclude that more RT-PCR tests on placental and cord blood samples are needed in order to safely make definite conclusions.

RESUMEN

The aim of this study was to determine the accuracy of the 24-h urine collection in preeclamptic pregnant women. This study included 65 singletons with preeclampsia and 53 singleton patients in a control-matched group. The ratio of inaccurate 24-h urine collection was measured by calculating expected urine creatinine excretion according to the proportion of pre-pregnancy weight and the lean body mass (LBM) of the patients. Comparisons were made between the accurately-collected 24-h urine protein excretion rates and the instant and 24-h urine protein/creatinine (P/Cr) and albumin/creatinine (A/Cr) ratios. Twenty-four-hour urine collection used to diagnose patients with preeclampsia was incorrectly collected 15-73.5% of the time among the patients and the control group. Instant and 24-h urine P/Cr and A/Cr ratios were correlated with total 24-h proteinuria among the patients in whom urine was collected correctly. Considering the 24-h urine P/Cr ratio, rather than the 24-h urine protein excretion value, is a better way to diagnose preeclampsia. IMPACT STATEMENT What is already known on this subject? Twenty-four-hour urine collection is considered as the gold standard of diagnosing proteinuria in preeclampsia, in case of the correctly collected. What do the results of this study add? Generally, in the literature the correctness of 24-h proteinuria is not questioned. However, it is actually quite important in daily practice to make the correct diagnosis of the proteinuria not to misdiagnose preeclampsia. What are the implications of these findings for clinical practice and/or further research? In this article, we aimed to show the importance of accurately collected 24-h urine in preeclampsia. We consider and advise to change the gold standard of this technique to 24-h protein/creatinine (P/Cr) ratio, in order to make correct diagnosis of the preeclampsia.

RESUMEN

Gestational diabetes is the most encountered metabolic disease in pregnancy and affects both the mother and fetus adversely. Low-grade subchronic inflammation is associated with gestational diabetes development. Platelets (PLT) play role in blood coagulation and inflammatory process. We aimed to compare the various platelet indices in patients with GDM and healthy pregnant controls and to determine whether PLT indices are useful in Gestational diabetes diagnosis. The present study was performed at the Zonguldak Bulent Ecevit University, School of Medicine, Department of Obstetrics and Gynecology. Statistically significant relationships with plateletcrit, mean platelet volume, and platelet distribution width and patients with GDM were found (p < 0.001). Plateletcrit had higher sensitivity and specificity than other platelet indices. Although plateletcrit is a largely unknown or an underestimated parameter in complete blood count, it gives more precise information than platelet count and mean platelet volume. Platelet-related indices and their determination are inexpensive and routinely ordered markers, the significance of which is often ignored. They may be useful in screening for gestational diabetes as an adjunct to oral glucose tolerance test.

RESUMEN

PURPOSE: Women with stress urinary incontinence (SUI) often require combined pelvic reconstructive surgeries because of shared risk factors of pelvic organ prolapse. The purpose of this study was to evaluate efficacies of Burch colposuspension, transobturator tape (TOT), and single-incision needleless (DynaMesh®-SIS minor) procedures in patients with SUI who also underwent combined pelvic reconstructive surgery or hysterectomy. METHODS: We performed this retrospective cohort study that comprising 122 patients who either underwent Burch colposuspension (n:43), TOT (n:40), or SIS (n:39) procedures along with pelvic reconstructive surgery or hysterectomy between January 2010 and July 2018. During the clinical follow-up, we analyzed cure rates, and surgical success rates of SUI surgery, quality of life, and symptom severity by IIQ-7, UDI-6, SSI, SSQ-8, OAB-V8, and PGI-I scale scores. The primary outcome was surgical success, whereas secondary outcomes included complications and patient-reported outcomes in the quality of life. RESULTS: We found that surgical success rates were higher in Burch group than SIS group and higher in TOT group than in SIS group (88.4% vs 61.5% and 87.5% vs 61.5%, p = 0.003). The quality of life was lower in SIS group than in Burch group. CONCLUSIONS: Both Burch and TOT are effective procedures in patients with SUI who require additional pelvic surgeries. Although surgical outcomes of SIS procedure in patients with SUI who underwent concomitant pelvic surgeries in our study were not promising, further studies with SIS are needed to clarify these observations.

RESUMEN

BACKGROUND: Polycystic ovary syndrome (PCOS) is the most frequent cause of anovulatory infertility. In women with PCOS, effective ovulation induction serves as an important first-line treatment for anovulatory infertility. Individual participant data (IPD) meta-analysis is considered as the gold standard for evidence synthesis which provides accurate assessments of outcomes from primary randomised controlled trials (RCTs) and allows additional analyses for time-to-event outcomes. It also facilitates treatment-covariate interaction analyses and therefore offers an opportunity for personalised medicine. OBJECTIVE AND RATIONALE: We aimed to evaluate the effectiveness of different ovulation induction agents, in particular letrozole alone and clomiphene citrate (CC) plus metformin, as compared to CC alone, as the first-line choice for ovulation induction in women with PCOS and infertility, and to explore interactions between treatment and participant-level baseline characteristics. SEARCH METHODS: We searched electronic databases including MEDLINE, EMBASE and Cochrane Central Register of Controlled Trials up to 20 December 2018. We included RCTs comparing the following interventions with each other or placebo/no treatment in women with PCOS and infertility: CC, metformin, CC plus metformin, letrozole, gonadotrophin and tamoxifen. We excluded studies on treatment-resistant women. The primary outcome was live birth. We contacted the investigators of eligible RCTs to share the IPD and performed IPD meta-analyses. We assessed the risk of bias by using the Cochrane risk of bias tool for RCTs. OUTCOMES: IPD of 20 RCTs including 3962 women with PCOS were obtained. Six RCTs compared letrozole and CC in 1284 women. Compared with CC, letrozole improved live birth rates (3 RCTs, 1043 women, risk ratio [RR] 1.43, 95% confidence interval [CI] 1.17-1.75, moderate-certainty evidence) and clinical pregnancy rates (6 RCTs, 1284 women, RR 1.45, 95% CI 1.23-1.70, moderate-certainty evidence) and reduced time-to-pregnancy (6 RCTs, 1235 women, hazard ratio [HR] 1.72, 95% CI 1.38-2.15, moderate-certainty evidence). Meta-analyses of effect modifications showed a positive interaction between baseline serum total testosterone levels and treatment effects on live birth (interaction RR 1.29, 95% CI 1.01-1.65). Eight RCTs compared CC plus metformin to CC alone in 1039 women. Compared with CC alone, CC plus metformin might improve clinical pregnancy rates (8 RCTs, 1039 women, RR 1.18, 95% CI 1.00-1.39, low-certainty evidence) and might reduce time-to-pregnancy (7 RCTs, 898 women, HR 1.25, 95% CI 1.00-1.57, low-certainty evidence), but there was insufficient evidence of a difference on live birth rates (5 RCTs, 907 women, RR 1.08, 95% CI 0.87-1.35, low-certainty evidence). Meta-analyses of effect modifications showed a positive interaction between baseline insulin levels and treatment effects on live birth in the comparison between CC plus metformin and CC (interaction RR 1.03, 95% CI 1.01-1.06). WIDER IMPLICATIONS: In women with PCOS, letrozole improves live birth and clinical pregnancy rates and reduces time-to-pregnancy compared to CC and therefore can be recommended as the preferred first-line treatment for women with PCOS and infertility. CC plus metformin may increase clinical pregnancy and may reduce time-to-pregnancy compared to CC alone, while there is insufficient evidence of a difference on live birth. Treatment effects of letrozole are influenced by baseline serum levels of total testosterone, while those of CC plus metformin are affected by baseline serum levels of insulin. These interactions between treatments and biomarkers on hyperandrogenaemia and insulin resistance provide further insights into a personalised approach for the management of anovulatory infertility related to PCOS.

RESUMEN

Objectives. The frequency, predisposing factors and impact of urinary incontinence (UI) on quality of life (QoL) during pregnancy were investigated. Materials and Method. A preliminary cross-sectional survey was studied among pregnant women between January and July of 2014. A total of 132 pregnant women were recruited using a questionnaire form for sociodemographic features, the Turkish version of the International Consultation on Incontinence-Short Form (ICIQ-SF), for the characteristics of UI and Wagner's Quality of Life scale to assess impact on QoL. p < 0.05 was set significant. Results.Urinary incontinence was present in 56 out of 132 pregnant women (42.4%, UI-present group): mean age, 26.7 ± 5.4y(p = 0.780); median height, 160 cm (min-max: 153-176, p = 0.037); median BMI, 28.7 kg/m(2)(min-max: 22.4-50.0, p = 0.881); urine leakage occurred per week once (n = 18, 32.1%), twice or thrice (n = 8, 14.3%); per day few times (n = 14, 25%), once (n = 5, 8.9%) and always (n = 8, 14.3%) with mainly a small amount of urine leakage (n = 33, 58.9%) or a moderate (n = 4, 7.1%). There were statistically significant relationships between QoL scores and frequency of UI (p = 0.002) or amount of leakage (p = 0.002). Impact on QoL scores ranged from mild (n = 33, 58.9%), moderate (n = 4, 7.1%) to severe (n = 4, 7.1%) levels in daily life. UI impacted the daily life activities of women by making them less likely to undertake activities outside their homes (23.2%), by affecting their working performance and friendships (8.9%), their daily home activities (7.1%), their general health status (12.5%), their sexual relations (12.5%), by making them more nervous or anxious (10.7%) and by the need to wear pads or protectors (25%). ANOVA, Tukey, and Tamhane tests as the minimal important difference model yielded significant relevance between statistical analyses and clinical outcomes by using standard deviations (p = 0.001, 0.001 and 0.005 respectively). The following features favored the occurence of UI: Age (OR = 0.845, 95% CI [0.268-2.669]), being a housewife (OR = 1.800, 95% CI [0.850-3.810]), anemia (OR = 0.939, 95% CI [0.464-1.901]), parity (OR = 0.519, 95% CI [0.325-0.829]), miscarriage (OR = 1.219, 95% CI [0.588-2.825]) and living in rural areas (OR = 1.800, 95% CI [0.887-3.653]). Height (p = 0, 037), educational status (0.016), miscarriage (0.002), parity (0.006) and place of living (0.020) were significant factors. Conclusions.Many pregnant women are suffering from UI, which warrants a significant public health consideration in the region. Age, height, being a housewife or graduation level higher than primary school, living in rural, parity, miscarriage, and anemia were the factors in favor of the onset of UI. The authors plan a health promotion program in the region according to the results in order to provide information to health caregivers, especially family physicians, and to educate women about the predictors of UI and pelvic floor exercises for primary prevention and secondary relief of UI during and after pregnancy and provide some hygienic supplies to the poor in this aspect.

RESUMEN

INTRODUCTION: Peritoneal adhesions are pathological fibrous connections between peritoneal surfaces resulting from incomplete peritoneal repair. Adhesions cause various health problems ranging from pelvic pain and bowel obstruction to infertility. To date, no effective agent exists for intra-abdominal adhesion prevention. Bromelain is the crude extract of the pineapple and it has fibrinolytic, antithrombotic, and anti-inflammatory properties. Bromelain has been shown to be effective for removing necrotic tissues and has been found to be effective for treating various wounds, inflammatory conditions, and thrombotic pathologies. In the present study, we evaluated bromelain as a novel agent for preventing intra-abdominal adhesions. METHODS: Group 1 (control group): Adhesions were produced by cecal abrasion method, and no treatment was applied. Group 2 (i.p. bromelain-treated group): After adhesion formation, 10 mg/kg/BW of bromelain dissolved in 1 mL saline solution was applied intraperitoneally for 10 days. Group 3 (i.p. saline-treated group): After adhesion formation, 1 mL saline solution was applied intraperitoneally for 10 days. On postoperative day 10, all animals were sacrificed. RESULTS: All 30 rats survived surgery. Throughout the follow-up period, no complications were observed. Statistically significant differences were found between the groups with regards to macroscopic adhesion scores, inflammation, fibrosis and neo-vascularization (p < 0.001, <0.001, p = 0.001, p = 0.002, respectively). Macroscopic and histopathologic (inflammation, fibrosis, neo-vascularization) adhesion scores were lowest in the bromelain-treated group. CONCLUSION: Bromelain, acting through its barrier, anti-inflammatory, antioxidant, and proteolytic effects and without increasing bleeding tendency or having any adverse effects on wound healing, may be a suitable agent for intra-abdominal adhesion prevention.
