ABSTRACT

OBJECTIVE: This study focuses on evaluating the effectiveness, safety and efficacy of 2 surgical tissue extraction methods for treating bowel endometriosis: natural orifice specimen extraction (NOSE) and minilaparotomy. DATA SOURCES: A systematic search was conducted in MedLine, Embase, and Cochrane Library databases in October 2023, without date restrictions. METHODS OF STUDY SELECTION: This study included studies that directly compared NOSE and minilaparotomy in colectomy patients due to endometriosis. Primary outcomes were defined as operation duration, length of hospital stay, intraoperative blood loss, and major postoperative complication rates. The Clavien-Dindo classification was used to categorize complications. Statistical analysis was performed using Review Manager Software by Cochrane, with a DerSimonian and Laird random-effects model to account for anticipated high heterogeneity. Subgroup analysis was conducted for patients undergoing full laparoscopic (L/S) resection. TABULATION, INTEGRATION AND RESULTS: Out of 1236 identified studies, 6 met the inclusion criteria, comprising 372 patients. One study was a randomized controlled trial, and 5 were observational. Operation duration did not significantly differ between NOSE and minilaparotomy (MD: -10.85 min; 95% CI: [-23.33, 1.63]; p = .09). NOSE was associated with a significantly reduced length of hospital stay (MD: -0.76 day; 95% CI: [-1.21, -0.31]; p = .008). The major postoperative complication rates were 3.77% for NOSE and 5.55% for minilaparotomy, with no significant difference (OR: 0.84; 95% CI: [0.27, 2.60]; p = .76). Subgroup analysis revealed that Full L/S had significantly shorter operation duration (MD: -26.06 min; 95% CI: [-45.85, -6.27]; p = .01), reduced length of stay (MD: -0.75 day; 95% CI: [-1.25, -0.25]; p = .003), and lower blood loss (MD: -15.01 mL; 95% CI: [-29.64, -0.37]; p = .04). CONCLUSION: NOSE emerged as a potentially safer alternative to minilaparotomy for tissue extraction in colectomy for bowel endometriosis. However, standardization of the procedure and additional randomized controlled trials are needed to validate these findings.

ABSTRACT

Combinatorial CRISPR-Cas screens have advanced the mapping of genetic interactions, but their experimental scale limits the number of targetable gene combinations. Here, we describe 3Cs multiplexing, a rapid and scalable method to generate highly diverse and uniformly distributed combinatorial CRISPR libraries. We demonstrate that the library distribution skew is the critical determinant of its required screening coverage. By circumventing iterative cloning of PCR-amplified oligonucleotides, 3Cs multiplexing facilitates the generation of combinatorial CRISPR libraries with low distribution skews. We show that combinatorial 3Cs libraries can be screened with minimal coverages, reducing associated efforts and costs at least 10-fold. We apply a 3Cs multiplexing library targeting 12,736 autophagy gene combinations with 247,032 paired gRNAs in viability and reporter-based enrichment screens. In the viability screen, we identify, among others, the synthetic lethal WDR45B-PIK3R4 and the proliferation-enhancing ATG7-KEAP1 genetic interactions. In the reporter-based screen, we identify over 1,570 essential genetic interactions for autophagy flux, including interactions among paralogous genes, namely ATG2A-ATG2B, GABARAP-MAP1LC3B and GABARAP-GABARAPL2. However, we only observe few genetic interactions within paralogous gene families of more than two members, indicating functional compensation between them. This work establishes 3Cs multiplexing as a platform for genetic interaction screens at scale.

ABSTRACT

OBJECTIVE: The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) outbreak had an enormous global impact. Pregnant women with SARS-CoV-2 appear to have higher morbidity and mortality. This study aimed to evaluate the effect of the severity of maternal SARS-CoV-2 infection on neonatal outcomes. STUDY DESIGN: The clinical and laboratory data of 40 women and neonates evaluated retrospectively. RESULTS: This retrospective study showed that SARS-CoV-2 infection had an adverse impact on neonatal outcomes proportionally with the maternal disease severity including increased prematurity rates, postnatal resuscitation need, prolonged hospital stay and longer ventilatory support requirement in infants born to mothers with moderate or severe disease. CONCLUSION: Maternal disease severity had adverse effects on neonatal outcomes. The severity of maternal disease was found to be associated with increased rates of prematurity, requirement of postnatal resuscitation, prolonged hospital stay, and longer ventilatory support. KEY POINTS: · SARS-CoV-2 pandemic is a problem for pregnant women.. · Vertical transmission has been shown in limited studies.. · Maternal disease severity may have impact on neonatal outcomes..

ABSTRACT

OBJECTIVE: This study sought to compare the efficacy and outcomes of fetal intracardiac intraventricular and interventricular septal potassium chloride (KCl) injections during the induced fetal demise process in a cohort of pregnant women with severe fetal abnormality who opted for late termination of pregnancy (TOP). MATERIALS AND METHODS: This study consisted of 158 pregnant women who requested late TOP for severe fetal abnormality between 22 and 36 weeks of pregnancy. Participants were randomly assigned with the simple randomization procedure to one of two feticide procedure groups: the intraventricular KCl injection group and the interventricular septal KCl administration group. We studied the clinical outcomes of both the feticide procedures. RESULTS: The median total dose of strong KCl was significantly lower in the interventricular septal KCl administration group (3 mL) than in the intraventricular KCl injection group (5 mL, p < 0.001). The median time to reach asystole and the median total duration of the procedure was significantly shorter in the interventricular septal KCl administration group (42 s and 85 s, respectively) than in the intraventricular KCl injection group (115 s and 150 s, respectively, p < 0.001). We detected a statistically significant correlation between the gestational week at feticide and the total dose of KCl (r = 0.705, p < 0.001), time to reach asystole (r = 0.653, p < 0.001), and total duration of the procedure (r = 0.683, p < 0.001). CONCLUSION: KCl administered directly into the interventricular septum induces immediate and permanent fetal cardiac asystole with a 100% of success rate without comprising maternal safety. We did not observe any maternal complications related to the procedure in our cases. Since the consequences of failed feticide procedure are challenging for both parents and healthcare providers, and providers are also concerned about potential legal implications regarding an unintended live birth, it is crucial to guide a strict protocol to confirm permanent fetal cardiac asystole.

ABSTRACT

BACKGROUND: Although the influence of microbial invasion of the amniotic cavity on the development of spontaneous preterm delivery is unquestionable, the use of an invasive procedure to diagnose the status of an infection limits its clinical translation. OBJECTIVE: This study aimed to use exploratory and confirmatory analyses to investigate the presence of vaginal metabolome expression of microbial invasion of the amniotic cavity in women diagnosed as having preterm labor using high-performance liquid chromatography. STUDY DESIGN: In 140 women with singleton pregnancies and a diagnosis of preterm labor at <34 weeks' gestation, we analyzed vaginal amino acid concentrations using high-performance liquid chromatography. Vaginal samples were collected shortly after the amniocentesis performed at admission to rule out microbial invasion of the amniotic cavity. Data were normalized for the median of all the amino acid concentrations evaluated. Microbial invasion of the amniotic cavity was defined as a positive aerobic or anaerobic amniotic fluid culture for the presence of bacteria or yeast or Ureaplasma species or Mycoplasma hominis in the mycoplasma culture or a positive polymerase chain reaction result for 16S rRNA gene sequence. Exploratory analysis was performed in half of the sample and confirmatory analysis in the other half. We compared vaginal amino acid concentrations between women with and without microbial invasion of the amniotic cavity in both cohorts. The area under the curve with 95% confidence interval values were calculated for vaginal amino acids with significant differences. RESULTS: In the exploratory cohort (2014-2015), 17 of 76 women (22.3%) had microbial invasion of the amniotic cavity compared with 14 of 72 (19.4%) in the confirmatory cohort (2016-2017). In the exploratory cohort, we found significantly higher amino acid concentrations of vaginal taurine, lysine, and cysteine and significantly lower concentrations of vaginal glutamate, aspartate, and the aspartate to asparagine ratio. These significant differences were confirmed in the confirmatory cohort. The area under the curve of these vaginal amino acids to predict microbial invasion of the amniotic cavity ranged between 0.72 and 0.79, with cysteine being the amino acid with the best performance with an area under the curve of 0.79 (95% confidence interval, 0.71-0.88). CONCLUSION: We found the vaginal metabolome expression of microbial invasion of the amniotic cavity in women with preterm labor and intact membranes. These findings might open the possibility to develop noninvasive diagnostic tools of microbial invasion of the amniotic cavity with the aim of selecting women who would most likely benefit from an amniocentesis for this indication.

ABSTRACT

STUDY OBJECTIVE: Laparoscopic excision of a scar pregnancy and isthmocele repair with a barbed suture. DESIGN: A step-by-step explanation of the laparoscopic excision technique of a scar pregnancy and isthmocele repair. SETTING: Cesarean scar pregnancy occurs as a result of attachment of the products of conception to the uterine scar [1-3]. In the present case, a 34-year-old, gravida 4, para 1 patient with a history of 1 miscarriage and 1 ectopic pregnancy was diagnosed with type 2 cesarean scar pregnancy at 7 weeks of gestation. Dilation and curretage was performed at the 8th week of gestation to terminate the pregnancy. On ultrasonography performed 1 month later, placental material underlying the isthmocele was observed. Her beta human chorionic gonadotropin level was 13 836 mIU/mL. She was followed up for 1.5 months until the beta human chorionic gonadotropin levels were negative. However, the mass underneath the scar had grown larger, measuring up to 5 × 6 cm. Laparoscopy was performed because the patient reported vaginal spotting and pelvic pain. The incision was sutured with a synthetic absorbable unidirectional barbed suture (Stratafix Knotless Tissue Control Device; Ethicon Inc., Somerville, NJ). No residual scar defect was visible on follow-up ultrasonography 1 week and 1 month after surgery. CONCLUSION: Barbed sutures ease the repair of uterine scar defects and can provide ideal reapproximation of thick myometrial tissue. Laparoscopic treatment of a scar pregnancy and isthmocele repair are effective and safe modes of treatment.

ABSTRACT

BACKGROUND: We aimed to determine if there is a difference in the size of the cesarean scar defect using saline infusion sonography (SIS) performed on the postoperative third month in patients who underwent single- or double-layered unlocked closure of their uterine incision during their first cesarean delivery. METHODS: This study was conducted as a prospective cross-sectional study between February 2015 and January 2016 in patients admitted to the labour ward of the Kanuni Sultan Suleyman Training and Research Hospital who subsequently underwent their first delivery by cesarean section. Patients with a previous history of cesarean delivery, preterm pregnancies less than 34 gestational weeks, patients lost to follow-up or those who had an IUD inserted after delivery were excluded from the study. Out of the 327 patients who underwent primary cesarean delivery, 280 were included into the study. Patients were divided into two groups according to the single- (n:126) or double-layered (n:156) closure of their uterine incision. The maternal age, height, weight, obstetric and gynecologic histories, medical histories, indications for their cesarean delivery, technique of uterine closure, birth weight of the baby, duration of the cesarean delivery, need for extra suturing and transfusion were recorded. A Saline infusion sonography (SIS) was performed 3 months postoperatively to determine the presence, depth and length of the cesarean scar. The residual myometrial thickness overlying the scar defect and the fundal myometrial thickness were recorded. RESULTS: No difference was detected between the groups with respect to patient characteristics, whether the operation was elective or emergent, the type of anesthesia used, need for extra suturing, incidence of bladder injuries or uterine atony, need for blood transfusions, duration of labour or cervical dilatation and effacement between the two groups. No statistically significant difference was detected between the two groups with respect to the length and depth of the scar defect. CONCLUSION: Single- or double-layered closure of the uterus does not seem to affect the size of the uterine scar defect detected on SIS 3 months following the first cesarean delivery.

ABSTRACT

BACKGROUND: Tracing stable isotopes, such as 13C using various mass spectrometry (MS) methods provides a valuable information necessary for the study of biochemical processes in cells. However, extracting such information requires special care, such as a correction for naturally occurring isotopes, or overlapping mass spectra of various components of the cell culture medium. Developing a method for a correction of overlapping peaks is the primary objective of this study. RESULTS: Our computer program-MIDcor (free at https://github.com/seliv55/mid_correct) written in the R programming language, corrects the raw MS spectra both for the naturally occurring isotopes and for the overlapping of peaks corresponding to various substances. To this end, the mass spectra of unlabeled metabolites measured in two media are necessary: in a minimal medium containing only derivatized metabolites and chemicals for derivatization, and in a complete cell incubated medium. The MIDcor program calculates the difference (D) between the theoretical and experimentally measured spectra of metabolites containing only the naturally occurring isotopes. The result of comparison of D in the two media determines a way of deciphering the true spectra. (1) If D in the complete medium is greater than that in the minimal medium in at least one peak, then unchanged D is subtracted from the raw spectra of the labeled metabolite. (2) If D does not depend on the medium, then the spectrum probably overlaps with a derivatized fragment of the same metabolite, and D is modified proportionally to the metabolite labeling. The program automatically reaches a decision regarding the way of correction. For some metabolites/fragments in the case (2) D was found to decrease when the tested substance was 13C labeled, and this isotopic effect also can be corrected automatically, if the user provides a measured spectrum of the substance in which the 13C labeling is known a priori. CONCLUSION: Using the developed program improves the reliability of stable isotope tracer data analysis.

ABSTRACT

BACKGROUND: Placenta percreta is a life-threatening condition that places patients at risk of massive bleeding. It necessitates very complicated surgery and can result in mortality. Caesarean hysterectomy is the accepted procedure worldwide; however, recent studies discussing conservative treatment with segmental resections have been published. Foetal extraction and segmental resection can be performed through the same incision (single uterine incision) or through two different incisions (double uterine incision). In this study, we aimed to evaluate the effectiveness and results of the double incision technique. METHODS: Twenty-two patients with a diagnosis of placenta percreta who underwent conservative surgery were included. Segmental resection was performed via single incision in ten patients and double incision in twelve patients. RESULTS: There was no difference between the patients who underwent segmental resection via single and double incision in terms of age, gravida, number of previous caesarean deliveries, gestational age at delivery, or rate of elective surgeries. The operation time, transfusion requirement, intensive care unit admission, total hospitalization and success of conservative surgery were comparable between the groups. CONCLUSIONS: Based on the outcomes of our study, double uterine incision allows for the safe extraction of the foetus during uterus-preserving surgery in patients with placenta percreta without worsening the results compared to single uterine incision. TRIAL REGISTRATION: NCT02702024 , Date of registration: February 26, 2016, retrospectively registered.

ABSTRACT

A series of cyclometallated platinum(IV) compounds (3a, 3a' and 3b') with a meridional [C,N,N'] terdentate ligand, featuring an halido and an aryl group in the axial positions has been evaluated for electrochemical reduction and preliminary biological behavior against a panel of human adenocarcinoma (A-549 lung, HCT-116 colon, and MCF-7 breast) cell lines and the normal bronquial epithelial BEAS-2B cells. Cathodic reduction potentials (shifting from -1.463 to -1.570V) reveal that the platinum(IV) compounds under study would be highly reluctant to be reduced in a biological environment. Actually ascorbic acid was not able to reduce complex 3a', the most prone to be reduced according its reduction potential, over a period of one week. These results suggest an intrinsic activity for the investigated platinum(IV) complexes (3a, 3a' and 3b'), which exhibit a remarkable cytotoxicity effectiveness (with IC50 values in the low micromolar range), even greater than that of cisplatin. The IC50 for A-549 lung cells and clog P values were found to follow the same trend: 3b'>3a'>3a. However, no correlation was observed between reduction potential and in vitro activity. As a representative example, cyclometallated platinum(IV) compound 3a', exercise its antiproliferative activity directly over non-microcytic A-549 lung cancer cells through a mixture of cell cycle arrest (13% arrest at G1 phase and 46% arrest at G2 phase) and apoptosis induction (increase of early apoptosis by 30 times with regard to control). To gain further insights into the mode of action of the investigated platinum(IV) complexes, drug uptake, cathepsin B inhibition and ROS generation were also evaluated. Interestingly an increased ROS generation could be related with the antiproliferative activity of the cyclometallated platinum(IV) series under study in the cisplatin-resistant A-549 lung and HCT-116 cancer cell lines.

ABSTRACT

PURPOSE: The purpose of this study was to investigate fetal ductus venosus (DV) wave velocities, DV velocity ratios, and DV diastolic time intervals to derive additional information on fetal cardiac function in the presence of an intracardiac echogenic focus (IEF). METHODS: Seventy fetuses at 19-28 weeks of gestation with an IEF and 63 control fetuses were screened using two-dimensional and power Doppler echocardiography. DV wave velocities, DV velocity ratios, and diastolic time intervals were measured. The aortic peak velocity, pulmonary artery peak velocity, left ventricular shortening fraction, and right ventricular shortening fraction, atrioventricular early-diastolic filling velocity (E), atrial contraction velocity (A), and E/A ratio were also measured. RESULTS: The study and control groups were similar in terms of maternal age, body mass index, and gestational age in weeks at the time of examination (p > 0.05). Significant between-group differences were found in DV v-descent (p = 0.03) and a-wave velocities (p = 0.04). CONCLUSIONS: Although the presence of an IEF in the fetal heart does not influence conventional measurements (DV velocity ratios and DV diastolic time intervals), it is associated with changes in DV v-descent and a-wave velocities. These changes may be indirectly related to reduced end-systolic relaxation and augmented atrial contraction in the fetal heart. We therefore suggest examination of DV flow velocities in fetuses with IEF.

ABSTRACT

OBJECTIVE: To evaluate the associations between adverse perinatal outcomes and serum transaminase levels at the time of diagnosis in patients with intrahepatic cholestasis of pregnancy. METHODS: We performed a retrospective analysis of patients hospitalized for evaluation of intrahepatic cholestasis of pregnancy from January 2013 to June 2014 in a tertiary center. Seventy-one patients were divided into two groups according to the presence (Group I) or absence of adverse perinatal outcomes (Group II). RESULTS: The mean aminotransferase levels and conjugated bilirubin levels at the time of diagnosis were significantly higher in Group I than in Group II. Receiver operating characteristic curve analysis revealed that the alanine aminotransferase level could predict adverse perinatal outcomes with 76.47% sensitivity and 78.38% specificity, and the cut-off value was 95 IU/L. Among patients with intrahepatic cholestasis of pregnancy, those with adverse perinatal outcomes were significantly older, had an earlier diagnosis, and had higher alanine aminotransferase levels. Using the 95-IU/L cut-off value, patients with intrahepatic cholestasis of pregnancy had a 3.54-fold increased risk for adverse perinatal outcomes. CONCLUSIONS: Patients with intrahepatic cholestasis of pregnancy and high alanineaminotransferase levels should be followed up for possible adverse perinatal outcomes.

ABSTRACT

Selenium supplement has been shown in clinical trials to reduce the risk of different cancers including lung carcinoma. Previous studies reported that the antiproliferative and pro-apoptotic activities of methylseleninic acid (MSA) in cancer cells could be mediated by inhibition of the PI3K pathway. A better understanding of the downstream cellular targets of MSA will provide information on its mechanism of action and will help to optimize its use in combination therapies with PI3K inhibitors. For this study, the effects of MSA on viability, cell cycle, metabolism, apoptosis, protein and mRNA expression, and reactive oxygen species production were analysed in A549 cells. FOXO3a subcellular localization was examined in A549 cells and in stably transfected human osteosarcoma U2foxRELOC cells. Our results demonstrate that MSA induces FOXO3a nuclear translocation in A549 cells and in U2OS cells that stably express GFP-FOXO3a. Interestingly, sodium selenite, another selenium compound, did not induce any significant effects on FOXO3a translocation despite inducing apoptosis. Single strand break of DNA, disruption of tumour cell metabolic adaptations, decrease in ROS production, and cell cycle arrest in G1 accompanied by induction of apoptosis are late events occurring after 24h of MSA treatment in A549 cells. Our findings suggest that FOXO3a is a relevant mediator of the antiproliferative effects of MSA. This new evidence on the mechanistic action of MSA can open new avenues in exploiting its antitumour properties and in the optimal design of novel combination therapies. We present MSA as a promising chemotherapeutic agent with synergistic antiproliferative effects with cisplatin.

ABSTRACT

Fetal sacrococcygeal teratomas (SCTs) occur in one to two per 20 000 pregnancies that cause high-output cardiac failure. High-output cardiac failure leads to polyhydramnios, hydrops, intrauterine fetal demise and preterm birth. Vascular disruption defects refer to those involving the interruption or destruction of some part of the fetal vasculature. We present a rare case of huge SCT causing multiple fetal disruption defects like cleft lip and palate and limb anomalies besides hydrops.

ABSTRACT

BACKGROUND: To evaluate the patterns of lymphatic spread in epithelial ovarian cancer (EOC) macroscopically confined to the ovary and to determine risk factors for lymph node metastasis. MATERIALS AND METHODS: All patients with clinically apparent stage IA/B/C EOCs who underwent staging surgery between January 2003 and February 2013 were retrospectively identified. RESULTS: Two hundred and thirty-six (n = 236) consecutive patients were operated for primary epithelial ovarian carcinoma. Sixty-two of these patients (26.2 %) who underwent a comprehensive staging procedure including pelvic and paraaortic lymphadenectomy were diagnosed with tumors confined to one or two ovaries (stage IA/B/C). Of these 62 patients, 17 (27.4 %) had upstaged disease and 8 (12.9 %) had lymph node metastasis. Tumor histology was serous in 25 patients (40.3 %), mucinous in 23 patients (37 %), endometrioid in 9 patients (14.5 %), and clear cell in 5 patients (8 %). Positive lymph node status was found in 20 % (5/25) of those with serous histology while this rate was only 8.1 % (3/37) in those with non-serous disease. Although the presence of ascites was not associated with an increased risk of lymph node involvement (p = 0.24), positive peritoneal cytology (p = 0.001) and grade 3 disease (p = 0.001) were significant predictors of lymph node involvement. CONCLUSION: All patients diagnosed with EOC macroscopically confined to the ovary should be considered for comprehensive staging surgery including pelvic and paraaortic lymphadenectomy.

ABSTRACT

In this study, a total of 323 drag swab samples were taken from laying hen fresh feces from 3 different provinces (Kirklareli, Edirne, and Tekirdag), which are located in the European part of Türkiye. According to the ISO 6579: 2002 method, 17.3% of the samples were found positive for Salmonella. Obtained 56 Salmonella isolates were serotyped by slide agglutination using antisera according to Kauffmann White Le Minor Scheme. Sixteen serotypes of Salmonella were identified as S. Typhimurium (28.6%), S. Kentucky (17.9%), S. Abony (16.1%), S. Infantis (8.9%), S. Enteritidis (5.4%), S. Anatum (3.6%), S. Saintpaul (3.6%), S. Szentes (1.8%), S. Dibra (1.8%), S. Fallowfield (1.8%), S. Kimuenza (1.8%), S. Escanaba (1.8%), S. Nagoya (1.8%), S. Mbandaka (1.8%), S. Agona (1.8%), and Salmonella II 17: e, n, x, z15: 1,6 (1.8%). Isolations of S. Kimuenza, S. Escanaba, and S. Nagoya from laying hens are reported for the first time in Türkiye. The isolations of S. Dibra, S. Fallowfield, S. Szentes, and Salmonella II 17: e, n, x, z15: 1,6 from laying hens are the first report in the world. A total of 56 Salmonella isolates were tested for susceptibility to amoxicillin-clavulanic acid, cefepime, azithromycin, cefoxitin, and trimethoprim/sulfamethoxazole by the disk diffusion method. While 10% of S. Kentucky isolates were resistant to ofloxacin, and S. Kimuenza was only resistant to chloramphenicol.

ABSTRACT

The aim of this study was to evaluate maternal serological status and fetal sonographic findings of Cytomegalovirus (CMV) infection. This is a retrospective study performed at Perinatology Department of Istanbul Basaksehir Çam and Sakura City Hospital. A computerized search was conducted to identify cases who underwent prenatal diagnosis of fetal CMV infection between September 2020 and December 2023. We identified nine cases with fetal CMV infection. The clinical data of the patients, gestational age at the time of diagnosis, serological, sonographic findings, and pregnancy outcomes were analyzed. A computer search of the database was made for the seroprevalance of CMV-IgM and CMV-IgG in our population. The CMV-IgM and IgG results of the 1235 patients who underwent CMV screening in the first trimester between September 2020 and December 2023 were evaluated. Fetal CMV infection was identified in nine patients. None of the 9 cases showed maternal CMV-IgM positivity. Seven of the 9 patients showed high IgG avidity index. Pregnant population had 98 % positivity for CMV-IgG. The evaluation of serologic tests for CMV is not straightforward in the second and third trimester. IgM and IgG avidity should be interpreted with caution in the second and third trimester. In the presence of ultrasound findings suggesting fetal CMV infection and CMV-IgG positivity, invasive diagnostic tests rather than serological test should be discussed with the patient, and non-primary infections should always be considered to minimize overlooked fetal cytomegalovirus infections and missed antiviral treatment opportunity.

ABSTRACT

Entrapped placenta following vaginal delivery is an uncommon complication. In resistant cases, it needs to be removed by laparotomy, although this is exceptionally rare. Here, we report a 28-year-old woman, 33 weeks pregnant through in vitro fertilization, who delivered a premature male baby weighing 2400 grams with an Apgar score of 7. After delivery, the placenta remained in the unicornuate uterus. Ultrasound ruled out placenta accreta spectrum, and manual removal attempts under anesthesia failed due to lower uterine segment contraction despite using nitroglycerine. Conservative management with misoprostol and broad-spectrum antibiotics was initiated. However, increasing C-reactive protein levels and abdominal pain necessitated a computerized tomography scan, revealing the placenta trapped in the unicornuate uterus. Thirty-six hours after the delivery, the decision was made to remove the placenta laparoscopically instead of laparotomy. A unicornuate uterus containing a placenta on the right and the left rudimentary horn connected to the right uterus with bilateral adnexa, including theca cysts, were revealed during laparoscopic observation. No pelvic organ injury was noted. The placenta was removed via a fundal incision with a monopolar hook and using claw traumatic forceps. The uterus was closed with V-lock sutures; additional Z-sutures were applied. A 270-gram entire placenta was extracted using an endo bag successfully. The patient was discharged several days after the procedure without any complications. Laparoscopic extraction of a third-trimester placenta can successfully be used in resistant cases while avoiding laparotomy, even in the early postpartum period.

ABSTRACT

OBJECTIVE: This study aimed to evaluate the value of platelet activation markers in predicting preeclampsia and its severity. Preeclampsia is a serious pregnancy complication that affects 3-5% of pregnancies and can lead to significant morbidity and mortality for both the mother and the fetus. METHODS: The study included 99 patients diagnosed with preeclampsia and 60 healthy pregnant women as a control group. Platelet activation markers such as mean platelet volume (MPV), platelet distribution width (PDW), platelet count, and plateletcrit were evaluated along with other clinical parameters. RESULTS: The results of the study showed that platelet activation markers, particularly PDW and MPV, are valuable in the diagnosis and follow-up of preeclampsia. However, they are not sufficient to predict the severity of the disease. CONCLUSION: The study suggests that platelet activation markers could aid in predicting, diagnosing, and managing preeclampsia. However, further research is needed to determine the role of these markers in predicting the severity of the disease. The findings of this study could contribute to the development of more effective strategies for the prevention and management of preeclampsia, which could ultimately improve maternal and fetal outcomes.


OBJETIVO: El estudio tuvo como objetivo determinar el valor de los marcadores de activación plaquetaria en la predicción de la preeclampsia y su gravedad. MÉTODO: Se incluyeron 99 pacientes diagnosticadas con preeclampsia, incluyendo 36 casos graves, y un grupo control de 60 mujeres embarazadas sanas. Se evaluaron diversas variables, como el volumen plaquetario medio, el recuento de plaquetas, el hematocrito plaquetario y la amplitud de distribución plaquetaria. RESULTADOS: Los resultados mostraron que el volumen plaquetario medio y la amplitud de distribución plaquetaria son parámetros valiosos en el diagnóstico y seguimiento de la preeclampsia, aunque no son suficientes para predecir su gravedad. El análisis estadístico reveló que la edad, el volumen plaquetario medio, la amplitud de distribución plaquetaria, la semana de gestación y los puntajes de Apgar al primer y quinto minuto fueron significativamente diferentes en el grupo de preeclampsia en comparación con el grupo control. CONCLUSIONES: En conclusión, estos resultados sugieren que los marcadores de activación plaquetaria pueden ser útiles para el diagnóstico y seguimiento de la preeclampsia, y que el volumen plaquetario medio y la amplitud de distribución plaquetaria, por ser parámetros económicos y accesibles, podrían ayudar a predecir, diagnosticar y manejar esta complicación durante el embarazo.

ABSTRACT

OBJECTIVE: To compare salpingectomy and detorsion procedures and investigate the biochemical and histopathological changes in the fallopian tubes in the experimentally isolated fallopian tube torsion model in rats. DESIGN: Experimental study. SETTING: Experimental surgery laboratory in a training and research hospital. ANIMAL(S): Twenty-seven Sprague-Dawley rats in the reproductive period. INTERVENTION(S): Group 1, control group (n = 6); group 2, bilateral total salpingectomy group after 4 hours of tubal ischemia (n = 7); group 3: 4 hours of bilateral tubal ischemia plus 1 week of reperfusion (n = 7); and group 4, 4-hour period of bilateral tubal ischemia plus 30 days of reperfusion (n = 7). A 22-gauge catheter was administered before and after surgery using methylene blue through the uterine horn of the rat to evaluate tubal patency. MAIN OUTCOME MEASURE(S): Preoperative and postoperative serum antimüllerian hormone (AMH) levels, histopathological examination of the rat tuba uterine and histopathological damage scores, antioxidant compounds (superoxide dismutase [SOD], catalase, and glutathione peroxidase [GSH-Px]), and oxidative stress end product levels (malondialdehyde [MDA] and 8-hydroxy-2'-deoxyguanosine [8-OHdG]). RESULT(S): Although a significant difference was observed in the tissue SOD, GSH-Px, MDA, and 8-OHdG values, no significant difference was observed between the groups in serum samples. The tissue SOD and tissue GSH-Px levels in group 2 significantly decreased, and a significant increase was observed in the tissue MDA and 8-OHdG values in group 2. Among the histopathological parameters, epithelial changes, vascular congestion, and the total fallopian tube mean damage score of 4 showed a significant decrease in group 4. When the methylene blue transitions before and after ischemia-reperfusion injury were compared, the values of the methylene blue transition after ischemia-reperfusion injury in groups 2-4 significantly decreased. When the serum AMH levels were analyzed, the postoperative AMH value in group 2 significantly increased. CONCLUSION(S): This study reveals that biochemical and histopathological improvement is observed in the fallopian tube tissues gradually when the detorsion procedure is performed for the necrotized tubal tissue instead of salpingectomy. Although there is restoration of epithelial integrity after reperfusion, tubal passage remains absent. CLINICAL TRIAL REGISTRATION NUMBER: This study was approved by the Local Ethics Committee for Animal Experiments of the Health Sciences University, Istanbul Hamidiye Medicine Faculty (approval number 27.05.2022-9269). The study followed the ethics standards recommended by the Declaration of Helsinki.
