Background and Objectives:
The timing of the reinstitution of warfarin after cesarean section (CS) delivery was not adequately addressed in the literature. This study aims to evaluate the risks of early versus late initiation of warfarin post-CS in patients with mechanical heart valves.
Methods:
This randomized, open-label cohort study included 114 pregnant women with mechanical heart valves planned to be delivered by CS at or after 28 weeks of gestation.Patients were randomly divided into two groups: Day-2-group, where warfarin was started on day 2, and Day-5-group, where warfarin was started on day 5 after CS. Maternal postoperative bleeding complications, mechanical valve thrombosis, need for blood transfusion or reoperation, and maternal mortality were identified.
Results:
Ten women (8.8%) had 11 bleeding complications, of whom 2 patients (20%) had intraperitoneal hemorrhage (none in Day-2-group and 2 in Day-5-group), 3 patients (30%) had subcutaneous hematoma (none in Day-2-group and 3 in Day-5-group), and 6 patients (60%) had sub-rectus hematoma (3 in Day-2-group and 3 in Day-5-group). No mechanical valve thrombosis, other thromboembolic events, or in-hospital maternal mortality were reported.
Conclusion
Despite the small number of events, the bleeding risk was lower in the group with early post-CS warfarin introduction than in the group with late warfarin introduction in patients with prosthetic heart valves.

Antibody cross-reactivity among flaviviruses is a major limitation in understanding the prevalence
without vector control measures. In this study, we investigated the presence of Zika virus (ZIKV)-specific
antibodies and the significance of their cross-reactivity with other flaviviruses, which could affect the
serological specificity in both symptomatic and asymptomatic pregnant women. Among the results
obtained from 217 serum samples tested for ZIKV-specific IgM and IgG, no specific predictions regarding
seropositivity or exposure due to extensive cross-reactivity with dengue virus (DENV) serology could be
made. Clear-cut positivity was observed in 1.8% (n = 4) and 1.0% (n = 2) for ZIKV IgM and IgG, respectively.
The same samples assessed for DENV showed 1.3% (n = 3) seropositivity each for IgM and IgG levels.
None of the samples were positive for ZIKV and DENV IgM or IgG. However, one sample (0.4%) tested
positive for ZIKV and DENV IgM. No significant correlation was observed between DENV IgM and IgG
when comparing the overlapped serotiters. On the other hand, the ZIKV IgG-positive sample showed
higher serotiters for DENV IgG, indicating cross-reactivity with ZIKV but without statistical significance.
Therefore, screening for the incidence of ZIKV becomes particularly challenging in a population where
the presence or pre-exposure to DENV is observed. Our observations further suggest that unless
flavivirus prevalence is properly addressed, determining the prevalence of ZIKV antibodies, which may
be confounded with other uninvestigated flaviviruses, will be complicated.

Aims:
This study focused on new fish feed additives that could supply a nutritional value and inhibit or eliminate
mycotoxins. Four novel feed additives, including Albizia lebbeck (L.), Leucaena leucocephala leaf extracts, Serendipita indica and Bacillus megaterium were applied to contaminated fish feed; besides investigating the toxicity of these new fish feed additives.
Methodology and results :
Our data exhibited that the different tested feed additives were not toxic for brine shrimp larvae or fish. Albizia lebbeck extract at a concentration 0.5% was highly effective in detoxifying mycotoxins with efficacy ratios of 88.01%, 93.89% and 92.89% for aflaB1, aflaG1 and CPA, respectively and L. leucocephala at 0.5% had efficacy ratios of 93.52% and 100% for aflaG1 and CPA, respectively. The addition of S. indica with a concentration of 0.75% was highly effective for the usage of good feed approximately free of mycotoxins, with efficacy ratios of 85.65%, 90.81% and 100% for aflaB1, aflaG1 and CPA, respectively. Moreover, B. megaterium, with a concentration of 0.75% was recommended for detoxification.
Conclusion, significance and impact of study
Studied new feed additives as feed additives in fish diets to eliminate mycotoxin with the potential of providing antioxidant activity. Results suggest that mycotoxins degradation can happen in vitro and in vivo by applying new fish feed additives in the fish diet.

Objective:
The present study aimed to detect the behavioral problems pre- and post-cochlear implantation in comparison to normal hearing group to be able to manage these problems to get more benefit from using cochlear implants.
Methods:
A case-control study included 53 children was done. They were divided into 2 groups, the control group included 28 healthy volunteers with normal hearing and the case group included 25 children with severe to profound hearing loss, fitted for cochlear implantation. The Arabic Child Behavior Checklist (CBCL) was used to detect different behavioral problems in both groups. Case group children were followed up and reassessed again by CBCL 3 months later after cochlear implantation.
Results:
There were highly significant differences regarding total scores of internalizing and externalizing domains of empirically based CBCL between the control group and the case group after cochlear implants (p=0.001). There were non-significant differences in children within case group (pre- and post-cochlear implantation) regarding emotional and behavioral problems on both empirically based and Diagnostic and Statistical Manual of Mental Disorders-based CBCL.
Conclusion
For better results, it is necessary to include a specialist of psychosomatic medicine in the cochlear rehabilitation teamwork.

Objective:
This study investigated the impact of two stimulation protocols using highly purified human menopausal gonadotropin (HP-hMG) on the endocrine profile, follicular fluid soluble Fas levels, and outcomes of intracytoplasmic sperm injection (ICSI) cycles.
Methods:
This prospective clinical trial included 100 normal-responder women undergoing ovarian stimulation for ICSI; 55 patients received concomitant follicle-stimulating hormone (FSH) plus HP-hMG from the start of stimulation, while 45 patients received FSH followed by HP-hMG during mid/late follicular stimulation. The primary outcome was the number of top-quality embryos. The secondary outcomes were the number and percentage of metaphase II (MII) oocytes and the clinical pregnancy rate.
Results:
The number of MII oocytes was significantly higher in the concomitant protocol (median, 13.0; interquartile range [IQR], 8.5–18.0 vs. 9.0 [8.0–13.0] in the consecutive protocol; p=0.009); however, the percentage of MII oocytes and the fertilization rate were significantly higher in the consecutive protocol (median, 90.91; IQR, 80.0–100.0 vs. 83.33 [75.0–93.8]; p=0.034 and median, 86.67; IQR, 76.9–100.0 vs. 77.78 [66.7–89.9]; p=0.028, respectively). No significant between-group differences were found in top-quality embryos (p=0.693) or the clinical pregnancy rate (65.9% vs. 61.8% in the consecutive vs. concomitant protocol, respectively). The median follicular fluid soluble Fas antigen level was significantly higher in the concomitant protocol (9,731.0 pg/mL; IQR, 6,004.5–10,807.6 vs. 6,350.2 pg/mL; IQR, 4,382.4–9,418.4; p=0.021).
Conclusion
Personalized controlled ovarian stimulation using HP-hMG during the late follicular phase led to a significantly lower response, but did not affect the quality of ICSI.

No systematic review to date has examined histopathological parameters in relation to native liver survival in children who undergo the Kasai operation for biliary atresia (BA).A systematic review and meta-analysis is presented, comparing the frequency of native liver survival in peri-operative severe vs. non-severe liver fibrosis cases, in addition to other reported histopathology parameters. Records were sourced from MEDLINE, Embase, and CENTRAL databases. Studies followed the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines and compared native liver survival frequencies in pediatric patients with evidence of severe vs. non-severe liver fibrosis, bile duct proliferation, cholestasis, lobular inflammation, portal inflammation, and giant cell transformation on peri-operative biopsies. The primary outcome was the frequency of native liver survival. A random effects meta-analysis was used. Twenty-eight observational studies were included, 1,171 pediatric patients with BA of whom 631 survived with their native liver. Lower odds of native liver survival in the severe liver fibrosis vs. non-severe liver fibrosis groups were reported (odds ratio [OR], 0.16; 95% confidence interval [CI], 0.08–0.33; I2 =46%). No difference in the odds of native liver survival in the severe bile duct destruction vs. non-severe bile duct destruction groups were reported (OR, 0.17; 95% CI, 0.00–63.63; I2 =96%). Lower odds of native liver survival were documented in the severe cholestasis vs. non-severe cholestasis (OR, 0.10; 95% CI, 0.01–0.73; I2 =80%) and severe lobular inflammation vs. non-severe lobular inflammation groups (OR, 0.02; 95% CI, 0.00–0.62; I2 =69%). There was no difference in the odds of native liver survival in the severe portal inflammation vs. non-severe portal inflammation groups (OR, 0.03; 95% CI, 0.00–3.22; I2 =86%) or between the severe giant cell transformation vs. non-severe giant cell transformation groups (OR, 0.15; 95% CI, 0.00–175.21; I2 =94%). The meta-analysis loosely suggests that the presence of severe liver fibrosis, cholestasis, and lobular inflammation are associated with lower odds of native liver survival in pediatric patients after Kasai.

Background/Aims:
Malignant portal vein thrombus (PVT) is found in up to 44% of patients with hepatocellular carcinoma (HCC). The nature of the thrombus influences treatment selection. The aim of this study was to assess the safety and efficacy of endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) in determining the nature of PVT in liver cirrhosis and/or HCC.
Methods:
A prospective study was conducted in 34 patients with liver cirrhosis and/or HCC with PVT. Under EUS guidance, PVT was punctured using a 22 G FNA needle (Cook Medical, Bloomington, IN, USA) followed by monitoring of the puncture tract using color Doppler. Patients were followed for adverse events 2 hours after recovery.
Results:
Throughout the 30-month study period, 34 patients, including 24 males with a mean age of 59±8 years, were enrolled. There were 8 patients with known HCC and 26 with no liver masses detected by computed tomography (CT). EUS-FNA from PVT was positive for malignancy in 3 patients (8.8%), of which only 1 patient was diagnosed with HCC by CT and 2 patients were newly diagnosed with HCC after EUS-FNA. No major complications were reported.
Conclusions
EUS-FNA is a safe and effective technique for determining the nature of PVT that does not fulfill the malignant criteria via imaging studies in patients with liver cirrhosis and/or HCC.
