Lung and diaphragm ultrasound as predictors of successful weaning from nasal continuous positive airway pressure in preterm infants.

OBJECTIVE: Assessment of the utility of lung and diaphragm ultrasound in the prediction of successful weaning from nasal continuous positive airway pressure (NCPAP) in preterm infants. STUDY DESIGN: This prospective cohort study was conducted on preterm infants who were considered ready for weaning off NCPAP. Lung and diaphragm ultrasound were performed just before and 3 h after weaning off NCPAP. The primary outcome was to evaluate the accuracy of lung ultrasound (LUS) in predicting successful weaning from NCPAP. RESULTS: Out of 65 enrolled preterm infants, 30 (46.2%) were successfully weaned from NCPAP to room air. The successful weaning group had higher gestational ages, lower incidences of previous invasive mechanical ventilation, and treated hemodynamically significant patent ductus arteriosus before the trial weaning. A LUS score of ≤6, measured before discontinuation of NCPAP, exhibited a predictive sensitivity of 80% and specificity of 75% for successful weaning (Area under the curve (AUC) = 0.865, ≤.001). When the LUS score was assessed 3 h after weaning from NCPAP, a cutoff point of ≤7 predicted successful weaning with a sensitivity and specificity of 90% and 60% respectively (AUC = 0.838, p ≤ .001). The diaphragmatic thickness fraction (DTF) was significantly lower in the successful weaning group. After adjustment for various factors, LUS score remained the only independent predictor of successful weaning. CONCLUSION: LUS score before weaning from NCPAP has a good sensitivity and specificity for predicting successful weaning from NCPAP in preterm infants. Diaphragmatic excursion and DTF were not good predictors.

Oxytocin versus a combination of tranexamic acid and ethamsylate in reducing intraoperative bleeding during abdominal myomectomy: a randomized clinical trial.

OBJECTIVE: Myomectomy is the preferred surgical approach to manage uterine fibroids. However, uterine fibroids are highly vascular tumors and, consequently, extremely susceptible to problems from myomectomy-related hemorrhage. Hence, we aim to compare oxytocin efficacy and safety profile versus tranexamic acid (TA) with ethamsylate for reducing bleeding during myomectomy. METHODS: This randomized, double-blinded multicenter study was performed between 20th August 2020 and 20th October 2020 at El-Galaa Teaching Hospital, El Hussein University Hospital, Al-Azhar University Hospitals of Assiut, and Al-Azhar University Hospitals of Damietta. One hundred and eighty patients were enrolled and divided into three groups: group (1) received an injection of 30 IU of oxytocin in 500 ml of normal saline; group (2) received injections of 1 g of TA, 250 mg of Ethamsylate, and 110 ml of normal saline IV; and group (3) received an injection of 110 ml of normal saline IV just before surgical incision. RESULTS: In 180 premenopausal women, oxytocin and TA with ethamsylate had no significant value in lowering intraoperative blood loss compared with the placebo for abdominal myomectomy (666.25 ± 183.03, 630.72 ± 145.83, and 646.67 ± 168.92, respectively (P = 0.506)). Non-significant trends were observed for a reduction in operation time (P = 0.760), intra/postoperative blood transfusion (P = 0.624), hospital stay (P = 0.986), postoperative fever (P = 0.659), and wound infection (P = 1). CONCLUSION: Oxytocin and TA with ethamsylate had no significant value in lowering intraoperative blood loss compared with the placebo for abdominal myomectomy which opens a new question about the role of the use of the hemostatic drug during myomectomy especially in centers with limited resources and had higher rates. TRIAL REGISTRATION: The study was registered on Pan African Clinical Trials Registry with the following number: PACTR202008739887429 and was approved on 24/08/2020.

Recurrence pattern of non-syndromic familial congenital heart diseases among a large cohort of families from Egypt.

BACKGROUND: Congenital heart diseases (CHD) are the commonest congenital anomalies with increased risk in children born from families with affected members. However, various recurrence patterns of CHDs have been reported in different populations. Therefore, this work aimed to assess the recurrence patterns of CHDs in a large sample of Egyptian families. METHODS: From January 2020 to October 2021, non-syndromic children with confirmed CHDs were recruited. Data were collected from guardians of the recruited children and hospital records, including the index case's cardiac diagnosis and CHD diagnosis of other affected family members with to determine their recurrence pattern, consanguinity, and multi-gestation status. RESULTS: A total of 130 recurrent cases with CHD were documented in 1960 families of children with CHD, including 66,989 members. Most recurrences were detected among first-degree relatives 50/130 (38.46%), especially siblings. Discordant recurrence was the most detected pattern (45.38%), followed by concordant recurrence (42.31%), and the least was group concordance. Recurrence rate was the highest for septal defects with left ventricular outflow tract obstruction (LVOTO) (11.8%) and anomalous venous drainage (11.1%), followed by septal defect with right ventricular outflow tract obstruction (RVOTO) (9.4%), isolated ventricular septal defect (VSD) category (8.2%) and LVOTO (8%). Familial recurrence was significant in consanguineous marriages [p = 0.0001; OR (95%CI) = 4.5 (2.25-9.01)] and in multi-gestations siblings: [p = 0.036; OR (95%CI) = 12.5(1.03-6.04)]. CONCLUSION: The recurrence of non-syndromic CHD is evident among first-degree relatives in Egyptian families, with mostly a discordant recurrence pattern. Recurrence was more notable in septal defects with LVOTO, anomalous venous drainage, septal defect with RVOTO, isolated VSD, and isolated LVOTO diagnostic categories. This finding will significantly impact family counseling, emphasizing higher recurrence in consanguineous parents.

Intraventricular hemorrhage prediction in premature neonates in the era of hemodynamics monitoring: a prospective cohort study.

Unstable hemodynamics and prematurity are the main players in intraventricular hemorrhage (IVH) development. Our objective was to study 8 the use of superior vena cava flow (SVCF), left ventricular output (LVO), and right ventricular output (RVO), and anterior cerebral artery (ACA) Doppler measures in prediction of IVH in the first week of life in preterm infant ≤ 32 weeks and birth weight ≤ 1500 g. This prospective cohort study was conducted in 55NICU of Alexandria University maternity hospital. Of 147 enrolled patients, 132 infants born ≤ 32 weeks GA and birth weight ≤ 1500 g were eligible for- the study. One hundred twenty-seven infants completed the study. Infants were scanned for ACA-RI using transfontanellar ultrasound, and SVCF, LVO, and RVO using functional echocardiography in the first 24 h after birth. Patients had another two scans on DOL3 and 7 to detect IVH development. Low SVCF and high ACA-RI significantly increased the risk of IVH using logistic regression models with OR, 3.16; 95%CI, 1.19-8.39; P = 0.02 and OR, 1.64; 95%Cl, 1.10-2.44; P = 0.02, respectively. Low SVCF and high ACA-RI significantly increased risk of catastrophic IVH P = 0.025 and 0.023, respectively. Combined use of low SVCF < 55 ml/kg/min and ACA-RI > 0.75 is predictor of IVH with sensitivity 40.8% and 82.1% specificity. CONCLUSIONS: There are strong relations between both low SVCF and high ACA-RI, and IVH development in premature neonates ≤ 32 weeks and birth weight ≤ 1500 g, with more significance towards catastrophic IVH. Admission RSS and LVO are the strongest factors affecting SVCF. Maternal anemia, patent ductus arteriosus size (mm/kg), and capillary refill time were significantly associated with high ACA-RI. These findings help in more understanding of pathophysiological factors affecting central perfusion that might affect the longer term neurodeveopmental outcome. TRIAL REGISTRATION: This work was registered in clinical trial.gv no NCT05050032. WHAT IS KNOWN: •Whether SVCF and RI-ACA can predict IVH in preterm neonates is still debatable. WHAT IS NEW: •Low SVC flow and high ACA-RI significantly increased risk of IVH, confirming the role of hypoperfusion-reperfusion cycle in IVH development. The most striking result that combined metrics using the cut-off value of < 41 ml/kg/min for SVCF and > 0.85 for ACA-RI "in the first day of life" can correctly reject the presence of IVH in 98% of patients "during the first week of life."

Relationship Between Ano-vaginal Distance and Bacterial Vaginosis (Cross-sectional Study).

Bacterial vaginosis is a vaginal condition caused by the overgrowth of anaerobic bacteria, owing to a shift in the vaginal microbial ecosystem. The aim of the study is to investigate the relationship between the ano-vaginal distance and the risk of developing bacterial vaginosis. In this cross-sectional study, the ano-vaginal distance was measured in 100 women participants complaining of vaginal discharge, divided into two groups. Group (1) consisted of 74 women who were negative for bacterial vaginosis, and group (2) consisted of 26 women who had bacterial vaginosis based on Amsel criteria. The negative cases for bacterial vaginosis had significantly longer ano-vaginal distance as compared with those who had bacterial vaginosis (3.85 ± 0.54 versus 3.38 ± 1.02). A positive correlation was detected between ano-vaginal distance and the risk of developing bacterial vaginosis. Further extensive studies are required to investigate this finding in different population groups.

Antenatal perineal massage benefits in reducing perineal trauma and postpartum morbidities: a systematic review and meta-analysis of randomized controlled trials.

INTRODUCTION AND HYPOTHESIS: Most vaginal births are associated with trauma to the perineum. The morbidity associated with perineal trauma can be significant, especially when it leads to third- and fourth-degree perineal tears. We hypothesized that antenatal perineal massage could decrease the incidence of perineal trauma, particularly severe perineal tears and other postpartum complications. METHODS: We searched four different databases from inception until August 2019 for the available trials. We included randomized controlled trials (RCTs) which assessed the effect of antenatal perineal massage (intervention group) versus control group (no antenatal perineal massage) in perineal trauma patients. Data were extracted from eligible studies and meta-analyzed using RevMan software. Primary outcomes were the risk of episiotomies and perineal tears. Secondary outcomes were perineal pain, second stage of labor duration, wound healing, anal incontinence, and Apgar scores at 1 and 5 min. RESULTS: Eleven RCTs with 3467 patients were analyzed. Women who received antenatal perineal massage had significantly lower incidence of episiotomies (RR = 0.79, 95% CI [0.72, 0.87], p < 0.001) and perineal tears (RR = 0.79, 95% CI [0.67, 0.94], p = 0.007), particularly the risk of third- and fourth-degree perineal tears (p = 0.03). Better wound healing and less perineal pain were evident in the antenatal perineal massage group. Antenatal perineal massage reduced the second stage of labor duration (p = 0.005) and anal incontinence (p = 0.003) with significant improvement in Apgar scores at 1 and 5 min (p = 0.01 and p = 0.02). CONCLUSIONS: Antenatal perineal massage is associated with a lower risk of severe perineal trauma and postpartum complications.

Cancer during pregnancy: perinatal outcome after in utero exposure to chemotherapy.

OBJECTIVES: To study the outcome of pregnancies complicated by malignant disease, in particular neonatal morbidity and mortality after in utero exposure to chemotherapy. METHODS: This prospective study included 118 patients diagnosed with malignant disease for the first time during pregnancy over an 8-year period (March 2003-March 2011). Outcome of neonates born to mothers who received chemotherapy during pregnancy was studied and compared with a control group. RESULTS: The commonest cancer type diagnosed during pregnancy (56/118 = 47.45 %) was breast carcinoma followed by lymphoma/leukemia (32 = 27.12 %). Gynecological tumors (all ovarian) represented 10.16 %, soft tissue tumors 5.08 %, colorectal 4.23 %, thyroid 2.54 % and others 3.38 %. Sixty-one (51.64 %) women received chemotherapy (average 3 ± 2 cycles) during the second and third trimesters. The incidence of neonatal survival, preterm birth, small for gestational age and congenital malformations was not significantly different between women who received chemotherapy during pregnancy and the control group. Five (4.23 %) women with advanced disease died during or shortly after termination of pregnancy. CONCLUSION: In utero exposure to chemotherapy during the second and third trimesters of pregnancy carries minimal morbidity to the unborn fetus.
