Visceral Leishmaniasis in a Twin Pregnancy: A Case Report and Review of the Literature.

Visceral leishmaniasis (VL), often referred to as kala-azar, is quite rare in developed countries during pregnancy. Only few studies have evaluated its impact on perinatal outcome. It is caused primarily by Leishmania donovani or Leishmania infantum and presents with a wide spectrum of clinical manifestations from cutaneous ulcers to multisystem disease. Differential diagnosis is challenging as symptoms and signs are insidious, mimicking other diseases. Misdiagnosis can result in severe adverse perinatal outcomes, even maternal/neonatal death. Early treatment with liposomal amphotericin-B (LAmB) is currently the first choice with adequate effectiveness. We report a rare case of VL in a twin pregnancy with onset at the second trimester, presenting with periodic fever with rigors, right flank pain, and gradual dysregulation of all three cell lines. The positive rK39 enzyme-linked immunosorbent assay test confirmed the diagnosis. Treatment with LAmB resulted in clinical improvement within 48 h and in the delivery of two late-preterm healthy neonates with no symptoms or signs of vertical transmission. The one-year follow-up, of the mother and the neonates, was negative for recurrence. To our knowledge, this is the first reported case of VL in a twin pregnancy, and consequently treatment and perinatal outcome are of great importance.

Serum Neuron-Specific Enolase as a Biomarker of Neonatal Brain Injury-New Perspectives for the Identification of Preterm Neonates at High Risk for Severe Intraventricular Hemorrhage.

Neonatal brain injury (NBI) is a critical condition for preterm neonates with potential long-term adverse neurodevelopmental outcomes. This prospective longitudinal case-control study aimed at investigating the levels and prognostic value of serum neuron-specific enolase (NSE) during the first 3 days of life in preterm neonates (<34 weeks) that later developed brain injury in the form of either periventricular leukomalacia (PVL) or intraventricular hemorrhage (IVH) during their hospitalization. Participants were recruited from one neonatal intensive care unit, and on the basis of birth weight and gestational age, we matched each case (n = 29) with a neonate who had a normal head ultrasound scan (n = 29). We report that serum NSE levels during the first three days of life do not differ significantly between control and preterm neonates with NBI. Nevertheless, subgroup analysis revealed that neonates with IVH had significantly higher concentrations of serum NSE in comparison to controls and neonates with PVL on the third day of life (p = 0.014 and p = 0.033, respectively). The same pattern on the levels of NSE on the third day of life was also observed between (a) neonates with IVH and all other neonates (PVL and control; p = 0.003), (b) neonates with II-IV degree IVH and all other neonates (p = 0.003), and (c) between control and the five (n = 5) neonates that died from the case group (p = 0.023). We conclude that NSE could be an effective and useful biomarker on the third day of life for the identification of preterm neonates at high risk of developing severe forms of IVH.

Delivery Progress, Labor Interventions and Perinatal Outcome in Spontaneous Vaginal Delivery of Singleton Pregnancies between Nulliparous and Primiparous Women with One Previous Elective Cesarean Section: A Retrospective Comparative Study.

Trial of labor after cesarean (TOLAC) is an alternative to repeated cesarean for women with singleton pregnancy and one previous transverse lower segment cesarean section (LSCS), resulting in most cases being a successful vaginal birth after cesarean section (VBAC). The primary objective of this study was to examine if the progress and the duration of the active first stage and the second stage of labor in nulliparous women with singleton pregnancy, spontaneous start of labor and vaginal birth differ from primiparous women succeeding VBAC after one previous elective LSCS in a country with a low cesarean section and high VBAC rate. Secondary objectives were to compare labor interventions and maternal-neonatal outcomes between the two groups. METHODS: This is a retrospective comparative study. Data were collected in a four-year period at the departments of Obstetrics and Gynecology at Kristianstad and Ystad hospitals in Sweden. Out of 14,925 deliveries, 106 primipara women with one previous elective LSCS and a spontaneous labor onset in the subsequent singleton pregnancy were identified. Of these women, 94 (88.7%) delivered vaginally and were included in the study (VBAC group). The comparison group included 212 randomly selected nulliparous women that had a normal singleton pregnancy, spontaneous labor onset and delivered vaginally. RESULTS: The rate of cervical dilation during the active first stage of labor as well as the duration of the second stage did not differ between the two groups. When adjusting for cervical dilation at admission, there was no significant difference between the two groups regarding the duration of the active phase of the first stage of labor. No significant differences were found in maternal-neonatal outcomes between the two groups except for higher birth weight in the VBAC group. The use of epidural analgesia was associated with slower dilation rhythm over the duration of the active phase and second stage of labor, need for labor augmentation, postpartum bleeding and need for transfusion at higher rates, irrespective of parity when epidural was used. CONCLUSIONS: Our study provides evidence that in women with one previous elective LSCS undergoing TOLAC in the subsequent pregnancy resulting in vaginal birth, the progress and duration of labor are not different from those in nulliparous women when labor is spontaneous and the it is a singleton pregnancy. The use of epidural was associated with prolonged labor, need for labor augmentation and higher postpartum bleeding, irrespective of parity. This information may be useful in patient counseling and labor management in TOLAC.

Lateral coagulation of the uterine artery at its origin prior to total laparoscopic hysterectomy. A randomized control trial.

BACKGROUND AND OBJECTIVES: Lateral occlusion prior to TLH has been suggested to reduce perioperative bleeding, operative time, and hospital stay. Furthermore, reducing the amount of bleeding and the length of the operation may affect parameters such as postoperative pain and the number of patients with postoperative vaginal vault hematoma. METHODS: This RCT was conducted at a single center at Odense University Hospital in Denmark. Between February 2016 and February 2019, a total of 58 patients undergoing TLH and bilateral salpingectomy for benign cases were recruited to the study. RESULTS: The mean operating time was significantly longer in the LA group with a mean difference between the two groups of six minutes. No other discrepancy regarding the primary outcomes was observed between the two groups. Total blood loss was similar in the two groups as well as the average hospital stay and the VAS score during the first seven days. 93% of the patients were discharged from the hospital within the first 24 h postoperatively. CONCLUSION: This RCT demonstrates that lateral occlusion of the uterine artery prior to TLH does not improve outcome for the patients and should therefore not be used as a standard procedure.

Investigation of Healthcare Professionals' Knowledge of Evidence-Based Clinical Practices for Preterm Neonatal Skin Care-A Pilot Study.

Neonatal skin care practices are considered crucial for a neonate's survival and are closely related to healthcare professionals' (HPs) knowledge and skills in delivering scientifically valid neonatal care interventions. In this descriptive cross-sectional pilot study, conducted in 2022, we aimed to assess HPs' basic theoretical knowledge of neonatal vernix caseosa, skin microbiota, and bathing as well as knowledge regarding evidence-based clinical practices (referred to as "clinical knowledge") for preterm neonatal skin care. Eligible participants were neonatologists, pediatricians, obstetricians, midwives and nurses working in the Greek setting. The research instrument was an online questionnaire designed by the research team. Finally, 123 HPs took part in the study. The theoretical, clinical and total knowledge scores were all significantly associated with age, healthcare profession and the sources used for education. Participants' theoretical and clinical knowledge scores were compared and found not to differ significantly (p = 0.566). A significant and positive correlation was found between theoretical and clinical knowledge scores. Thus, it is concluded that HPs should be updated with the latest evidence-based knowledge and clinical guidelines in order to provide neonatal skin care with high-quality standards.

Heterotopic pregnancy after bilateral salpingectomy, IVF and multiple embryos transfer. A case report and systematic review of the literature.

Heterotopic pregnancy after bilateral salpingectomy is an extremely rare complication of in vitro fertilisation/embryo transfer cycles. We report a case of a ruptured abdominal pregnancy on the omentum which was the stimulus to conduct the first systematic review on this complication according to 'PRISMA' guidelines (PROSPERO R.No CRD42020134104). PubMed, EMBASE and OpenAIRE databases were systematically reviewed for studies reporting (a) cases or case series of, (b) heterotopic pregnancies after, (c) prior bilateral salpingectomy, and (d) embryo transfer cycles. Twenty-two articles met the selection criteria including, with our case, 28 cases. Based on the results, clinical manifestations and laboratory findings can be unspecific or misleading. Transvaginal ultrasound is the main diagnostic tool as the ectopic foetus is more frequently located in the intramural part of the fallopian tubes, the tubal stump or the ovaries. Laparotomy or laparoscopy are the main treatment options with adequate perinatal outcome.

Lateral closure of the uterine artery prior to laparoscopic hysterectomy: a systematic review.

An alternative surgical technique with closure of the uterine artery at its origin, known as lateral approach prior to TLH, has been proposed and it may offer important benefits to both patients and surgeons. Our objectives were to review the current literature regarding surgical outcomes between lateral and conventional approach in relation to TLH. We followed the 'PRISMA' guidelines and conducted a systematic review, which involved searching PubMed and Embase databases for RCTs evaluating the topic. We identified four RCTs including 585 patients. Three of the four studies reported a significant lower bleeding during TLH with prior lateral approach. Operative time was also shorter in the lateral approach group compared to the conventional approach group in three studies.Our review provides evidence that lateral occlusion of the uterine arteries prior to total laparoscopic hysterectomy may be beneficial due to less blood loss and shorter perioperative time without compromising patient safety.

Serum glial fibrillary acidic protein as a biomarker of brain injury in premature neonates.

Neonatal brain injury is a serious adverse outcome of prematurity. Early detection of high risk premature neonates to develop neonatal brain injury is not currently feasible. The predictive value of many biomarkers has been tested, but none is used currently in clinical practice. The purpose of this study was to determine the levels and predictive value of serum glial fibrillary acidic protein (GFAP) in a prospective longitudinal case-control study during the first three days of life in premature neonates (<34 weeks of gestation) that later developed either intraventricular hemorrhage or periventricular leukomalacia. Each case (n=29) was matched according to birth weight and gestational age to one neonate with normal head ultrasound scans. No significant difference on GFAP levels was observed between the groups. Nevertheless, neonates with brain injury presented more frequently GFAP levels above the lowest detection limit (0.056 ng/ml) and this trend was significantly different during all days. The effectiveness of GFAP as an early biomarker of neonatal brain injury in premature neonates seems to be limited.

Serum Activin A as Brain Injury Biomarker in the First Three Days of Life. A Prospective Case-Control Longitudinal Study in Human Premature Neonates.

Disruption of normal intrauterine brain development is a significant consequence of premature birth and may lead to serious complications, such as neonatal brain injury (NBI). This prospective case-control longitudinal study aimed at determining the levels and prognostic value of serum activin A during the first three days of life in human premature neonates which later developed NBI. It was conducted in a single tertiary hospital and eligible participants were live-born premature (<34 weeks) neonates. Each case (n = 29) developed NBI in the form of an intraventricular haemorrhage, or periventricular leukomalacia, and was matched according to birth weight and gestational age to one neonate with normal head ultrasound scans. Serum activin A levels in both groups showed a stable concentration during the first three days of life as no difference was observed within the two groups from the first to the third day. Neonates diagnosed with NBI had significantly higher activin A levels during the first two days of life compared to control neonates and its levels correlated to the severity of NBI during the second and third day of life. Although serum activin A on the second day was the best predictor for neonates at risk to develop NBI, the overall predictive value was marginally fair (area under the ROC-curve 69.2%). Activin A, in combination with other biomarkers, may provide the first clinically useful panel for the early detection of premature neonates at high risk of NBI.

S100B as a biomarker of brain injury in premature neonates. A prospective case - control longitudinal study.

BACKGROUND: Neonatal brain injury (NBI) is a serious adverse outcome in premature neonates. We sought to determine the levels and prognostic value of serum S100B during the first three days of life in premature neonates (<34 weeks) that later developed NBI in the form of either intraventricular hemorrhage (IVH) or periventricular leukomalacia (PVL). METHODS: This is a prospective case - control longitudinal study. Each case (n = 29) was matched according to birthweight and gestational age to one neonate with normal head ultrasound scans. RESULTS: Neonates with NBI, had significantly higher S100B concentration during the first three days of life. In both groups S100B was significantly higher on the first day when compared to the next two days of life showing a downwards trend. Serum S100B on the first day was the best predictor for adverse neonatal outcome such as death or II-IV IVH grade. A cut-off value of 10.51 ng/ml serum S100B performed a sensitivity of 100% and a specificity of 93.9% to predict adverse neonatal outcome. CONCLUSION: Further research on the predictive value of serum S100B regarding NBI in premature neonates is of great interest and may provide the first clinically useful biomarker for early detection of neonates at high risk.

Postpartum human breast milk levels of neutrophil gelatinase-associated lipocalin (NGAL) and matrix metalloproteinase-9 (MMP-9)/NGAL complex in normal and pregnancies complicated with insulin-dependent gestational diabetes mellitus. A prospective pilot case-control study.

Neutrophil gelatinase-associated lipocalin (NGAL) and its complex with matrix metalloproteinase-9 (MMP-9) are present in a variety of human tissues and extracellular fluids. The aim of this pilot prospective case-control study was to detect NGAL and MMP-9/NGAL complex in human breast milk postpartum in women with normal and pregnancies that developed insulin-depended gestational diabetes mellitus (iGDM). We detected both biomarkers in human breast milk and concentrations were determined at the first day of colostrum secretion and two days after, in 22 normal pregnancies and 13 pregnancies with iGDM. Mean NGAL concentration decreased significantly from the first to the second sample, in both groups. Mean MMP-9/NGAL complex concentration decreased also significantly from the first to the second sample in normal pregnancies. Mean complex concentration was significantly higher in diabetic pregnancies compared to normal ones in the second sample.IMPACT STATEMENTWhat is already known on this subject? There is limited information on the presence of Neutrophil gelatinase-associated lipocalin (NGAL) in human milk and its physiological role.What the results of this study add? It is the first time that MMP-9/NGAL complex is detected in human milk in both normal and pregnancies complicated with insulin-depended gestational diabetes mellitus (iGDM). We confirm the presence of NGAL in colostrum of normal pregnancies and for the first time we detected NGAL in milk of pregnancies with iGDM. Concentrations of NGAL and MMP-9/NGAL complex tend to lessen postpartum in both groups. Pregnancies with iGDM compared to normal ones showed significantly higher concentration of MMP-9/NGAL complex two days after the beginning of lactation.What the implications are of these findings for clinical practice and/or further research? Further studies are necessary to determine the levels of NGAL and MMP-9/NGAL complex in human milk postpartum in normal and pathological pregnancies. Taking into consideration the well-established NGAL's ability to act as a bacteriostatic agent and its mucosal healing activity in gastrointestinal track, early breastfeeding of neonates is a logical recommendation. Finally, new studies on the actual physiological role of milk NGAL in neonates are necessary.

Questionnaire-based evaluation of sexual life after laparoscopic surgery for endometriosis: a systematic review of prospective studies.

INTRODUCTION: Endometriosis is a benign disease that affects women of reproductive age. Laparoscopic excision of endometriotic implants is considered one of the most effective therapeutic options. The disease and its treatment can have a major impact on psychosexual well-being but this is often overlooked as most studies focus on pain instead of sexuality in a holistic approach. The aim of this study was to review the current literature regarding the effect of laparoscopic surgery for endometriosis on quality of sexual life (QoSL). MATERIAL AND METHODS: Following the "Preferred Reporting Items for Systematic Reviews and Meta-Analyses" guidelines we conducted a systematic review that involved searching PubMed and Embase databases for prospective studies evaluating the effect of laparoscopic surgery for endometriosis on QoSL, using validated questionnaires. RESULTS: Of 357 papers, 17 were selected for full text evaluation. Twelve studies using seven different questionnaires fulfilled the inclusion criteria. All studies reported improvements in QoSL following laparoscopic surgery for endometriosis. A meta-analysis could not be performed due to substantial heterogeneity among the included studies arising from differences in questionnaires, follow-up duration, stages of endometriosis, use of hormonal treatment, and missing data. CONCLUSIONS: Laparoscopic excision of endometriosis can improve QoSL. However, there is a need for randomized controlled trials based on a new validated questionnaire regarding specifically QoSL in association with endometriosis. As sexual functioning is a complex phenomenon driven by multiple physical, psychological and social factors, QoSL should be holistically evaluated by a team of different healthcare providers, implementing treatment programs that are individualized to each woman.

Prediction of pre-eclampsia combining NGAL and other biochemical markers with Doppler in the first and/or second trimester of pregnancy. A pilot study.

OBJECTIVE: To determine the performance of maternal characteristics, Doppler and a set of biochemical markers for pre-eclampsia (PE) screening at 11+0 to 13+6 and 20+1 to 25+6 weeks' gestation. STUDY DESIGN: Prospectively enrolled women at 11+0 to 13+6 and 20+1 to 25+6 weeks. Maternal characteristics, uterine artery pulsatility index (UtA-PI), ductus venosus pulsatility index (DV-PI) and serum biomarkers including pregnancy associated plasma protein - A (PAPP-A), placental growth factor (PlGF), soluble fms-like tyrosine kinase 1 (sFlt-1), s-Flt-1/PLGF ratio, asymmetric dimethylarginine (ADMA), matrix metalloproteinase 9 (MMP-9), neutrophil gelatinase-associated lipocalin (NGAL) and MMP-9/NGAL complex were recorded. RESULTS: Combination of NGAL and BMI in a logistic regression model detected 70% of PE in the first trimester (p=0.001). Including UtA-PI and DV-PI in the model sensitivity reached 77.8% with 96.6% specificity (p=0.004). Combination of second trimester NGAL and s-Flt-1/PLGF ratio yield specificity 100% (p=0.001). Combination of second trimester UtA-PI with first trimester NGAL, BMI and age detected 80% of PE with specificity 91.9% (p=0.001). CONCLUSION: Combination of NGAL, maternal characteristics and Doppler parameters in the first and/or second trimester can detect a consistent number of PE pregnancies. NGAL is a potent new biomarker for the prediction of preeclampsia.

Maternal serum levels of neutrophil gelatinase-associated lipocalin (NGAL), matrix metalloproteinase-9 (MMP-9) and their complex MMP-9/NGAL in pregnancies with preeclampsia and those with a small for gestational age neonate: a longitudinal study.

BACKGROUND: The aim of this study was to determine maternal serum concentrations of neutrophil gelatinase-associated lipocalin (NGAL), matrix metalloproteinase-9 (MMP-9), and MMP-9/NGAL complex longitudinally in pregnancy, in normal pregnancies, in pregnancies that developed preeclampsia and in pregnancies that delivered a small for gestational age infant (SGA). METHODS: Neutrophil gelatinase-associated lipocalin, MMP-9, and MMP-9/NGAL were determined in the first, second, and third trimesters in 33 normal pregnancies, 12 pregnancies complicated by preeclampsia, and 14 pregnancies that delivered a SGA neonate. RESULTS: Median NGAL concentration (ng/mL) in normal pregnancies increased significantly from 12.8 in the first trimester to 25.9 in the second trimester (p = 0,002) and 48.0 (p < 0.0001) in the third trimester. In preeclamptic pregnancies, NGAL was significantly higher, compared with normal pregnancies, in the first (30.9; p = 0.006) and second (44.6; p = 0.015) trimesters. MMP-9 and MMP-9/NGAL complex concentrations in preeclamptic pregnancies did not differ significantly from normal pregnancies in either trimester. Pregnancies with an SGA infant did not have different marker concentrations in either trimester, compared with normal pregnancies. CONCLUSION: Maternal serum NGAL, MMP-9, and MMP-9/NGAL complex concentrations tend to increase during pregnancy in normal and preeclamptic pregnancies. NGAL was significantly elevated in the first and second trimesters, in pregnancies that later developed preeclampsia.
