RESUMO

OBJECTIVES: To assess the value of intraovarian PRP in women with low ovarian reserve. SEARCH STRATEGY: Screening of databases from inception to January 2023 using the keywords related to "Platelet-rich plasma" AND "poor ovarian reserve" OR "ovarian failure". SELECTION CRITERIA: Fourteen studies (1632 participants) were included, 10 included women with POR, 1 included women with POI and 3 included both POR and POI women. DATA COLLECTION AND ANALYSIS: Extracted data included study settings, design, sample size, population characteristics, volume, timing and preparation of PRP administration, and outcome parameters. MAIN RESULTS: AMH level was evaluated in 11 studies (2099 women). The mean difference (MD) was 0.09 with 95% CI of - 0.06, 0.24 (P = 0.25). Antral follicular count level was assessed in 6 studies (1399 women). The MD was 1.73 with 95% CI of 0.81, 2.66 (P < 0.001). The number of oocytes retrieved was evaluated in 7 studies (1413 women). The MD was 1.21 with 95% CI of 0.48, 1.94 (P = 0.001). CONCLUSION: This systematic review found a significant improvement of AFC, the number of retrieved oocytes, the number of cleavage embryos and the cancellation rate in women with POR. TRIAL REGISTRATION: Registration number CRD42022365682.

RESUMO

BACKGROUND: Nontuberculous mycobacteria (NTM) are emerging pathogens increasingly implicated in healthcare facility-associated (HCFA) infections and outbreaks. We analyzed the performance of statistical process control (SPC) methods in detecting HCFA NTM outbreaks. METHODS: We retrospectively analyzed 3 NTM outbreaks that occurred from 2013 to 2016 at a tertiary care hospital. The outbreaks consisted of pulmonary Mycobacterium abscessus complex (MABC) acquisition, cardiac surgery-associated extrapulmonary MABC infection, and a bronchoscopy-associated pseudo-outbreak of Mycobacterium avium complex (MAC). We analyzed monthly case rates of unique patients who had positive respiratory cultures for MABC, non-respiratory cultures for MABC, and bronchoalveolar lavage cultures for MAC, respectively. For each outbreak, we used these rates to construct a pilot moving average (MA) SPC chart with a rolling baseline window. We also explored the performance of numerous alternative control charts, including exponentially weighted MA, Shewhart, and cumulative sum charts. RESULTS: The pilot MA chart detected each outbreak within 2 months of outbreak onset, preceding actual outbreak detection by an average of 6 months. Over a combined 117 months of pre-outbreak and post-outbreak surveillance, no false-positive SPC signals occurred (specificity, 100%). Prospective use of this chart for NTM surveillance could have prevented an estimated 108 cases of NTM. Six high-performing alternative charts detected all outbreaks during the month of onset, with specificities ranging from 85.7% to 94.9%. CONCLUSIONS: SPC methods have potential to substantially improve HCFA NTM surveillance, promoting early outbreak detection and prevention of NTM infections. Additional study is needed to determine the best application of SPC for prospective HCFA NTM surveillance in other settings.

RESUMO

OBJECTIVE: To evaluate the diagnostic accuracy of ultrasound and in the diagnosis of Placenta accreta spectrum (PAS). DATA SOURCES: Screening of MEDLINE, CENTRAL, other bases from inception to February 2022 using the keywords related to placenta accreta, increta, percreta, morbidly adherent placenta, and preoperative ultrasound diagnosis. STUDY ELIGIBILITY CRITERIA: All available studies- whether were prospective or retrospective- including cohort, case control and cross sectional that involved prenatal diagnosis of PAS using 2D or 3D ultrasound with subsequent pathological confirmation postnatal were included. Fifty-four studies included 5307 women fulfilled the inclusion criteria, PAS was confirmed in 2025 of them. STUDY APPRAISAL AND SYNTHESIS METHODS: Extracted data included settings of the study, study type, sample size, participants characteristics and their inclusion and exclusion criteria, Type and site of placenta previa, Type and timing of imaging technique (2D, and 3D), severity of PAS, sensitivity and specificity of individual ultrasound criteria and overall sensitivity and specificity. RESULTS: The overall sensitivity was 0.8703, specificity was 0.8634 with -0.2348 negative correlation between them. The estimate of Odd ratio, negative likelihood ratio and positive likelihood ratio were 34.225, 0.155 and 4.990 respectively. The overall estimates of loss of retroplacental clear zone sensitivity and specificity were 0.820 and 0.898 respectively with 0.129 negative correlation. The overall estimates of myometrial thinning, loss of retroplacental clear zone, the presence of bridging vessels, placental lacunae, bladder wall interruption, exophytic mass, and uterovesical hypervascularity sensitivities were 0.763, 0.780, 0.659, 0.785, 0.455, 0.218 and 0.513 while specificities were 0.890, 0.884, 0.928, 0.809, 0.975, 0.865 and 0.994 respectively. CONCLUSIONS: The accuracy of ultrasound in diagnosis of PAS among women with low lying or placenta previa with previous cesarean section scars is high and recommended in all suspected cases.

RESUMO

Early in the pandemic of coronavirus disease 2019 (COVID-19), face masks were used extensively by the general public in several Asian countries. The lower transmission rate of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in Asian countries compared with Western countries suggested that the wider community use of face masks has the potential to decrease transmission of SARS-CoV-2. A risk assessment model named Susceptible, Exposed, Infectious, Recovered (SEIR) model is used to quantitatively evaluate the potential impact of community face masks on SARS-CoV-2 reproduction number (R0 ) and peak number of infectious persons. For a simulated population of one million, the model showed a reduction in R0 of 49% and 50% when 60% and 80% of the population wore masks, respectively. Moreover, we present a modified model that considers the effect of mask-wearing after community vaccination. Interestingly mask-wearing still provided a considerable benefit in lowering the number of infectious individuals. The results of this research are expected to help public health officials in making prompt decisions involving resource allocation and crafting legislation.

RESUMO

OBJECTIVE: To assess the value of intrauterine PRP to improve IVF outcome in women with previous implantation failure. METHODS: Screening of Pubmed, Web of Science, and other databases from inception to August 2022 using the keywords related to "platelet-rich plasma" OR "PRP" AND "IVF" "implantation failure." Twenty-nine studies (3308 participants) were included in our analysis, 13 were RCTs, 6 were prospective cohorts, 4 were prospective single arm, and 6 were retrospective analyses. Extracted data included settings of the study, study type, sample size, participants' characteristics, route, volume, timing of PRP administration, and outcome parameters. RESULTS: Implantation rate was reported in 6 RCTs (886 participants) and 4 non-RCTs (732 participants). The odds ratio (OR) effect estimate was 2.62 and 2.06, with 95% CI of 1.83, 3.76, and 1.03-4.11, respectively. Endometrial thickness was compared in 4 RCTs (307 participants) and 9 non-RCTs (675 participants), which showed a mean difference of 0.93 and 1.16, with 0.59-1.27 and 0.68-1.65 95% CI, respectively. CONCLUSION: PRP administration improves implantation, clinical pregnancy, chemical pregnancy, ongoing pregnancy, live birth rates, and endometrial thickness in women with previous implantation failure.

RESUMO

BACKGROUND: Objective to assess the value of preoperative tranexamic acid (TXA) in reduction of intraoperative and postoperative blood loss in high-risk cesarean delivery (CD). METHODS: A double blind randomized controlled trial included 160 high risk women who underwent elective lower segment CD. They were equally randomized to receive either 1 g of TXA or placebo 15 min before surgery. The primary outcome was Intraoperative blood loss. RESULTS: The estimated blood loss was significantly higher in the placebo group when compared to TXA group (896.81 ± 519.6 vs. 583.23 ± 379.62 ml, P < 0.001). Both postoperative hemoglobin and hematocrit were lower (9.2 ± 1.6 and 27.4 ± 4.1 vs. 10.1 ± 1.2 and 30.1 ± 3.4, P values < 0.001and 0.012 respectively) and their change percentages (15.41 vs. 7.11%, P < 0.001) were higher in the placebo group when compared to TXA one. The need for further ecbolics was higher in placebo group when compared to TXA group (46.25 vs. 13.75%, P < 0.001). CONCLUSION: Preoperative TXA is safe and effective in reducing blood loss during and after high-risk CD. TRIAL REGISTRATION: ClincalTrial.gov ID: NCT03820206 .

RESUMO

OBJECTIVE: We aimed to evaluate the hysteroscopic management of first-trimester pregnancy loss compared to surgical evacuation either blind or under ultrasonographic guidance . METHODS: This clinical trial included 315 women with first-trimester pregnancy loss, divided equally into three groups. Group 1 underwent traditional blind surgical evacuation, group 2 underwent ultrasound-guided evacuation, and group 3 underwent hysteroscopic management. All women were assessed for retained products, surgical complications, the need for further management, and pregnancy occurrence after evacuation within 2 years of follow up. RESULTS: The rate of presence of conception remnants and the need for further treatment was significantly higher in group 1 compared to groups 2 and 3 (4.8% vs. 0% vs. 0%, P = 0.012). The conception rate within 2 years was significantly lower in group 1 compared to groups 2 and 3 (57.4% vs. 73.2% vs. 82.7%, P = 0.002), and the duration needed to conceive was significantly prolonged in group 1 compared to groups 2 and 3 (9.8 vs. 8.3 vs. 6.9 months, P < 0.001). Interestingly, women who underwent hysteroscopic management needed a significantly shorter time to conceive than those who underwent ultrasound-guided evacuation (6.9 vs. 8.3 months, P = 0.006). CONCLUSIONS: Hysteroscopic management of first-trimester pregnancy loss was superior to ultrasound-guided surgical evacuation regarding the time interval to conceive. Both techniques were superior to the blind evacuation technique regarding removal of the whole conception remnants, need for further treatment and fertility outcomes. Clinical trial registration: It was first registered at ClinicalTrials.gov on 16/03/2017 with registration number NCT03081104.

RESUMO

BACKGROUND: The aim of the study is to evaluate the efficiency and safety of a novel technique to treat large benign ovarian cysts combining benefits of laparoscopic management along with mini-laparotomy without affection of the ovarian reserve. METHODS: The study included 112 women with large benign ovarian cyst candidate for ovarian cystectomy. The technique started with laparoscopy followed by guided cyst aspiration followed by exteriorization of the ovary through minilaprotomy and completion of cystectomy through microsurgical technique. The primary outcome was ipsilateral recurrence of the cyst. Other outcomes included ovarian reserve assessment and postoperative pain. RESULTS: The number of women with recurrence in the ipsilateral ovary after 12, 18 and 24 months were 5 (4.5%),16 (14.3%),20 (17.85%) respectively. Assessment of ovarian reserve revealed a significant decrease in the level of serum AMH (2.82 ± 0.44 vs. 2.50 ± 0.42) and a significant increase in AFC (3.5 ± 1.7 vs. 4.9 ± 1.3) after our novel technique in surgical treatment of ovarian cysts (P value < 0.001). The operative time was 50 ± 7 and 62 ± 7 min in unilateral and bilateral cysts respectively. CONCLUSIONS: Laparoscopic guided minilaparotomy is a safe and effective technique for the management of large benign ovarian cysts with minimal recurrence rate, ovarian reserve affection and adhesions.

RESUMO

OBJECTIVES: To evaluate the efficacy of misoprostol to minimized blood loss during and after cesarean delivery (CD). SEARCH STRATEGY: Screening of MEDLINE, EMBASE, Web of Science, the Cochrane Central Register of Controlled Trials from inception to February 2021 using the keywords related to misoprostol, CD, postpartum hemorrhage, and intraoperative blood loss and their MeSH terms. SELECTION CRITERIA: Only RCTs were included. Participants included women undergoing CD whether elective or selective. Thirty studies including 6593 women, 26 in English, 2 in Thai, 1 in French, and 1 in Chinese. DATA COLLECTION AND ANALYSIS: Data from all selected studies were extracted independently by two authors. Data extracted included location of the trial, sample size, inclusion and exclusion criteria, participants characteristics, intervention details including timing, dose, and route of drug administration. Outcomes assessed included estimated intraoperative and postoperative blood loss, occurrence of postpartum hemorrhage, the need for additional uterotonics, and hemoglobin difference. MAIN RESULTS: Four studies (968 women) compared preoperative to postoperative misoprostol and found a mean difference in intraoperative blood loss of -205.00 (-339.22, -70.77), p = 0.003 and in postoperative blood loss -216.27 (-347.08, -85.46), p < 0.001 and a significantly lower need for additional uterotonics with a risk ratio of 0.54 (0.46, 0.64), p < 0.00001. Twenty-two studies (4701 participants) compared misoprostol to oxytocin. There was a mean difference in intraoperative blood loss of -108.43 (-156.04, -60.82), p < 0.0001. Nine of these trials with 1978 participants evaluated postoperative blood loss. These found a mean difference of -64.12 (-116.19, -12.04) with a p = 0.02. Fourteen trials with 3166 participants measured the difference between preoperative and postoperative hemoglobin. These found a mean difference of -0.25 (-0.35, -0.15) with a p < 0.001. Twenty trials with 4416 participants measured the need for administration of additional uterotonics. These found a risk ratio of 0.62 (0.49, 0.78) with a p value of <0.001. CONCLUSION: The combined use of misoprostol and oxytocin during CD is effective in reducing blood loss during and after CD.

RESUMO

This randomised controlled trial aimed to compare the effect of early and delayed pushing during the second stage of labour in women with occipitoposterior (OP) malposition. It included 184 nulliparous women with OP position randomised to early pushing in which women were allowed to push within one hour after full cervical dilatation or delayed pushing in which women were asked not to push for maximum of three hours or start pushing when the vertex was visible. The primary outcome was successful vaginal delivery. The rate of spontaneous vaginal delivery was significantly higher in the early pushing group (80.4 vs. 60.9%, p=.004) while the rate of instrumental vaginal delivery (30.4 vs. 15.4%) and CS (8.7 vs. 4.3%) was significantly higher in the delayed pushing group. Women in the delayed pushing group showed a significantly longer duration of the second stage (129.4 ± 7.5 vs. 61.6 ± 15.3 minutes, p<.001) and shorter duration of pushing (219.8 ± 74.8 vs. 693.9 ± 145.2 seconds, p<.001) .The rate of 2nd and 3rd degree perineal lacerations (19.6 and 13% vs. 5.4 and 8.7% respectively, p=.013) and vaginal tears (41.3 vs. 8.7%, p<.001) was significantly higher in the early pushing group. We concluded that early pushing during the second stage of labour is associated with higher rates of spontaneous vaginal delivery and vaginal and perineal lacerations.Clinical trial registration NCT03121274.Impact StatementWhat is already known on this subject? Occipitoposterior malposition is common during delivery especially in primigravida and is associated with higher rates of instrumental delivery and caesarean section. It can be managed through early or delayed pushing.What the results of this study add? Early pushing is associated with higher rates of spontaneous vaginal delivery, perineal and vaginal tears, shorter duration of second stage of labour, shorter duration of pushing, lower rates of both instrumental vaginal delivery and caesarean section.What the implications are of these findings for clinical practice and/or further research? Early pushing during the second stage of labour is associated with higher rates of spontaneous vaginal delivery and vaginal and perineal lacerations in women with OP malposition and should be tried and not delaying the pushing.

RESUMO

OBJECTIVE: To assess the safety and efficacy of hyoscine butyl bromide (HBB) in primipara with prolonged 1st stage of labor. MATERIALS AND METHODS: A double-blinded randomized controlled trial included 100 primiparas diagnosed with prolonged labor. They were randomly divided two equal groups. Group I received 40 mg HBB intravenously. Group II received 2 ml of normal saline. The primary outcome was the duration of the 1st stage of labor. Secondary outcomes included success of vaginal delivery, rate of cervical dilation, duration of 2nd and 3rd stages of labor, causes of CS, neonatal outcome and drug side effects. RESULTS: The duration of the 1st stage was 322.3 ± 89.8 min in women who received HBB compared with 451.3 ± 198.3 min in the control women (P < 0.001). The rate of cervical dilation was increased from 0.4 ± 0.2 to 1.5 ± 0.6 in women who received HBB compared with its increase from 0.4 ± 0.1 to 0.9 ± 0.2 in other women (P < 0.001). The rate of CS were significantly higher in control women when compared to those received HBB (34 vs. 20%, P < 0.001). The commonest indication for the operation was arrest of cervical dilatation (28 and 16%, respectively). CONCLUSION: HBB is associated with shortening of the 1st stage, lowered rate of CS without any side effects. GOV ID: NCT03430362 date of registration 6 February 2018. Synopsis Hyoscine butyl bromide is associated with shortening of the 1st stage, lowered rate of CS in primiparas with prolonged labor.

RESUMO

The aim of our study was to assess the value of serum AMH in prediction of metaphase II oocytes in poor responders. We performed a prospective cohort study included 206 poor responders candidate for ICSI using antagonist protocol. They were classified into 3 groups. Group I included 50 women with AMH < 0.3 ng/ml, group II included 85 women with AMH 0.3-0.7 ng/ml and group III included 71 women with AMH > 0.7-1.0 ng/ml. The primary outcome parameter was the number of MII oocytes. There was a highly significant difference between the study groups regarding E2 at triggering (481.41 ± 222.653, 648.17 ± 264.353 and 728.74 ± 305.412 respectively, number of oocyte retrieved (2.37 ± 1.178, 3.38 ± 1.622 and 3.80 ± 1.427 respectively), number of MII oocytes (1.66 ± 1.039, 2.35 ± 1.171 and 2.61 ± 1.080 respectively), number of fertilized oocytes (1.39 ± 0.919, 1.91 ± 0.983 and 2.21 ± 0.937 respectively), , total number of embryos (1.34 ± 0.938, 1.76 ± 0.956 and 2.09 ± 0.907 respectively), clinical pregnancy rates (4.9 vs. 7.7 and 19.7% respectively). We concluded that AMH is a good predictor for number of MII oocytes in poor responders undergoing ICSI.

RESUMO

OBJECTIVE: Postnatal scanty milk secretion is a common complaint. Some physical and medical interventions were advocated to help milk production. These interventions should be effective and safe for the mother and the infant. This study aimed to compare the effects of low-level laser therapy and electroacupuncture on postnatal scanty milk secretion. STUDY DESIGN: A randomized controlled study conducted on 60 healthy primiparous mothers with insufficient lactation. They were randomly divided into three equal groups: group A (control), group B (those who received low-power He-Ne laser beam on both breasts), and group C (those who received faradic current stimulation at Spleen 6, Liver 3, and Small Intestine 1 acupuncture points on both sides). All participants received 10 mg Domperidone three times a day and were given advice about lactation, nutrition, and fluid intake. Evaluation was done before and after the treatment program. RESULTS: The mean serum prolactin, infant weight, and visual analog scale (VAS) score were significantly increased in the three groups posttreatment when compared with their corresponding levels pretreatment. Posttreatment serum prolactin was significantly elevated in group C more than the other two groups (p = 0.001 and 0.012, respectively). Also, it was significantly elevated in group B more than in group A (p = 0.001). The mean value of infant weight was significantly elevated in group C when compared with its corresponding values in both groups A (p = 0.001) and B (p = 0.029). The VAS score was significantly increased in both groups B and C when compared with group A (p = 0.001). CONCLUSION: Electroacupuncture is more effective than low-level laser therapy in increasing postnatal scanty milk secretion. CLINICAL TRIAL REGISTRATION: NCT03806062.

RESUMO

OBJECTIVE: This study aimed to evaluate the effect of vaginal progesterone (P) administration during the second and third trimesters of pregnancy on Doppler velocimetry of uterine, umbilical, and middle cerebral vessels. STUDY DESIGN: A prospective cohort study conducted on 80 women at risk for preterm labor. Uterine artery, umbilical artery, and middle cerebral artery (MCA) Doppler indices were measured before and after 1 week of administration of 200 mg twice daily vaginal P. The primary outcome parameter was the change of MCA pulsatility index (PI) after P administration. Secondary outcomes included changes in uterine artery and umbilical artery Doppler measurement. RESULTS: There was no significant changes of umbilical artery resistance index (RI) (0.69 ± 0.049 vs. 0.68 ± 0.041), umbilical artery PI (1.14 ± 0.118 vs. 1.11 ± 0.116), uterine artery RI (0.66 ± 0.12 vs. 0.66 ± 0.107), uterine artery PI (1.00 ± 0.26 vs. 1.016 ± 0.24), and MCA PI (1.27 ± 0.18 vs. 1.26 ± 0.23) measurements before and after 1 week of P administration, respectively. CONCLUSION: Administration of vaginal P has no significant effects on uterine artery, umbilical artery, and MCA Doppler indices.

RESUMO

Polymers are widely used but their flammability remains a serious issue causing fatalities and property damage. Herein we present an investigation into the effectiveness of graphene platelets (GnPs) to simultaneously improve the flame retardancy and mechanical properties of ethylene propylene diene monomer rubber (EPDM). EPDM was melt compounded respectively with GnPs and a commercial flame retardant (ammonium polyphosphate, APP) to produce two groups of composites. Although both fillers were well dispersed in EPDM, GnPs significantly improved the mechanical properties of EPDM whilst APP compromised some of the mechanical properties particularly at high fractions. This difference was attributed to the filler particle size and interfacial bonding. Through cone calorimetry testing, 21 wt% char yield was recorded for the EPDM/GnP composite at 12.0 vol%, in comparison with 8 wt% for the EPDM/APP composite. APP was able to lower the peak heat release rate (PHRR) and specific mass loss rate (MLR), but unfortunately it decreased the ignition time and fire performance index (FPI). By contrast, GnPs has been found to increase ignition time by 29% and FPI by 62%, while still achieved the same level of reductions in PHRR and specific MLR, demonstrating clear advantages over APP. During combustion the highly thermally stable GnPs bonded with the viscous, degraded EPDM macromolecules, forming a thick solid char layer which prevented the transport of heat and smoke, contributing to its superior flame retarding performance over APP.

RESUMO

To assess the value of endometrial thickness, volume, and sub-endometrial perfusion in women undergoing IVF. In 82 women candidate for ICSI, endometrial thickness and sub-endometrial perfusion were measured with a trans-vaginal 2 D ultrasound and 3 D power Doppler respectively on day of hCG trigger and Embryo transfer (ET). The primary outcome was the clinical pregnancy rate. Endometrial volume showing a statistically significant difference between pregnant and nonpregnant women (4.11 ± 1.19 vs. 3.4 ± 1.1 p = .019) on day of triggering and at ET (4.02 ± 1.15 vs. 3.45 ± 0.90, p = .022). VFI was significantly higher in pregnant group at both days of triggering and ET (0.54 ± 0.48 vs. 0.33 ± 0.31 and 0.47 ± 0.22 vs. 0.34 ± 0.2, p = .02). At cutoff values of 3.265 and 2.95 cm3 (70 & 80% sensitivity, specificity 64.5 & 51.6%, a positive predictive value 38.9 & 34.8%, and negative predictive value 87.0 & 88.9%) to predict pregnancy on the day of hCG trigger & ET respectively. Cutoff value for Endometrial VFI on the day of ET was 0.674 (sensitivity of 70%, specificity of 80.6%, PPV 53.8%, and NPV 89.3%). Higher endometrial volume and VFI were associated with pregnancy.
