RESUMO
This study describes the association of non-esterified fatty acids (NEFA) and calcium concentrations at calving with early lactation disease, reproductive performance and culling in 646 dairy cows from 13 commercial grazing dairy herds in Uruguay. During one year, health events were recorded from calving to 30 days in milk (DIM). The first author visited each farm every 20 days. During each visit, body condition score (BCS) was recorded (scale 1-5), defining BCS < 3 as suboptimal and BCS > 3 as optimal, and a blood sample was taken from cows between 0 and 4 DIM for metabolite determination. To evaluate the association between health events (i.e., retained placenta-metritis and clinical mastitis) and risk factors (parity, BCS, high NEFA (> 0.6â¯mmol/L) and subclinical hypocalcemia (SCH) (< 2.10â¯mM)) data were analysed using multivariable logistic regression models. To evaluate the association of health events and risk factors with reproductive performance and culling, data were analysed using Cox proportional hazard regression models. A risk factor and an outcome of interest were assumed to be associated at P < 0.05 and a tendency to be associated was defined at P < 0.10. Overall, 47â¯% (n = 303) of the cows showed elevated NEFA concentration and 77â¯% (n = 499) had SCH. In addition, 21.5â¯% (n = 139) of the cows recorded at least one clinical disease. Cumulative incidence was 17â¯% (n = 109) for clinical mastitis, 4.2â¯% (n = 27) for retained placenta (RP)-metritis and 1.4â¯% (n = 7) for lameness. Clinical mastitis was associated with parity, with lower odds in primiparous (PP) cows (OR = 0.42, P < 0.01). Cows in an optimal BCS also tended to have lower odds (OR = 0.66, P = 0.07). Moreover, high NEFA and SCH cows had higher odds of CM (OR = 4.5, P = 0.01 and OR = 1.75, P = 0.04, respectively). Retained placenta-metritis tended to be associated with high NEFA concentration (OR = 2.2, P = 0.06). Primiparous cows with suboptimal BCS showed an increased first insemination rate (HR = 2.34; P < 0.01). The risk of culling was lower in PP cows (HR = 0.19; P < 0.01) and in cows with optimal BCS and low NEFA concentration (HR = 0.38; P = 0.03). Our data show that metabolic challenge (defined as peripartum suboptimal BCS, high NEFA or SCH) is associated with increased odds of clinical mastitis and RP-metritis, decreased probability of insemination and increased hazard of culling. Under grazing conditions, we suggest that farm management to improve the metabolic adaptation to lactation represents an opportunity to enhance cow performance in terms of health, fertility and longevity.

Retained placenta is a common health issue, and appropriate prevention strategies are effective in postpartum health management. This study aimed to evaluate whether early intervention using GYS can prevent retained placenta and puerperal metritis, as well as enhance reproductive outcomes in cows. Each bovine in the GYS group (n = 591) received a single prophylactic dose of GYS (0.5 g/kg body weight) orally within 2 h after parturition, while those in the control group (n = 598) received no intervention. GYS treatment was associated with a decreased incidence of retained placenta (4.6% vs. 12.0%, P < 0.01, OR = 0.335), a lower puerperal metritis risk (8.8% vs. 20.1%, P < 0.01, OR = 0.369), and a reduced need for additional therapeutic antibiotics (11.2% vs. 26.1%, P < 0.01, OR = 0.342). We observed increases in the first service conception rate (59.7% vs. 49.1%, P < 0.01) and conception rate within 305 days postpartum (93.2% vs. 85.5%, P < 0.01) in the GYS group than in the control group. A significant decrease was observed in the number of services per conception (1.8 ± 1.1 vs. 2.1 ± 1.4, P < 0.01) and the calving-to-conception interval (83.6 ± 39.6 vs. 96.6 ± 52.5 days, P < 0.01) between the two groups. Additionally, GYS treatment increased milk yield on days 7, 14, and 28 postpartum without affecting milk fat, milk protein, somatic cell count (SCC), or milk urea nitrogen (MUN) on days 7 and 28 postpartum. Accordingly, the GYS was effective and safe in preventing retained placenta and to improve reproductive performance in cows. Therefore, it could be a prophylactic intervention for superior postpartum fertility in cows.

OBJECTIVE: To assess the accuracy of diagnosing retained products of conception (RPOC) in symptomatic versus asymptomatic women, and to identify potential divergent ultrasound features between these groups. METHODS: This retrospective study included women aged 17-50 years who underwent hysteroscopy for suspected RPOC during 2018-2021. Clinical and sonographic data were analyzed, and multivariable linear regression models employed, to examine correlations between RPOC and sonographic findings, and to compare diagnostic accuracy between symptomatic and asymptomatic women. RESULTS: Of the 225 women included, 123 (54.7 %) were symptomatic and 102 (45.3 %) were asymptomatic. Hysteroscopy complications were more frequent in asymptomatic women. Regarding sonography, statistically significant differences were not found between the groups in endometrial thickness or uterine fluid presence, but positive Doppler flow was more common in asymptomatic than symptomatic women. Endometrial thickness >1.49 cm demonstrated diagnostic utility, with similar sensitivity and specificity in the two groups. Multivariable models revealed significant associations of RPOC presence with endometrial thickness and Doppler flow in symptomatic women. In both groups, hysteroscopy enhanced diagnostic accuracy, with higher positive predictive values and lower false-positive rates compared to ultrasound alone. CONCLUSION: An endometrial thickness cutoff of 1.49 cm aids diagnosing RPOC. Doppler flow enhances diagnostic value in symptomatic women. Integration of hysteroscopy improves diagnostic accuracy compared to ultrasound alone. Regular sonographic assessment for women with identifiable risk factors assists in RPOC detection irrespective of symptoms.

A genome-wide association study of resistance to retained placenta (RETP) using 632,212 Holstein cows and 74,747 SNPs identified 200 additive effects with p-values < 10-8 on thirteen chromosomes but no dominance effect was statistically significant. The regions of 87.61-88.74 Mb of Chr09 about 1.13 Mb in size had the most significant effect in LOC112448080 and other highly significant effects in CCDC170 and ESR1, and in or near RMND1 and AKAP12. Four non-ESR1 genes in this region were reported to be involved in ESR1 fusions in humans. Chr23 had the largest number of significant effects that peaked in SLC17A1, which was involved in urate metabolism and transport that could contribute to kidney disease. The PKHD1 gene contained seven significant effects and was downstream of another six significant effects. The ACOT13 gene also had a highly significant effect. Both PKHD1 and ACOT13 were associated with kidney disease. Another highly significant effect was upstream of BOLA-DQA2. The KITLG gene of Chr05 that acts in utero in germ cell and neural cell development, and hematopoiesis was upstream of a highly significant effect, contained a significant effect, and was between another two significant effects. The results of this study provided a new understanding of genetic factors underlying RETP in U.S. Holstein cows.

In this study we explored the relationship between home birth rates and increasing rates of postpartum haemorrhage (PPH) and manual removal of the placenta (MROP). Data were used from the Dutch national perinatal registry (2000-2014) of women in midwife-led care. Adjusting for place of birth flattened the increasing trends of PPH and MROP. By adjusting for place of birth, the rising trend of MROP among multiparous women disappeared. This suggests that if home birth rates had not declined, PPH and MROP rates might not have increased as much. This study supports policies of enabling women to choose home births.

BACKGROUND: Most of critically ventilated patients with severe hemorrhagic shock experience metabolic acidosis, hypoalbuminemia, electrolyte imbalance, and increased production of free radical. Channa striata has a high content of albumin, an essential binding protein that contributes to homeostasis, and when combined with Moringa oleifera and Curcuma xanthorrhiza, they act as powerful antioxidants. Administration of C. striata, M. oleifera, and C. xanthorrhiza extract orally may benefit patient with hemodynamic issues, including significant blood loss. CASE REPORT: A 40-year-old Indonesian woman came to emergency department with decreased consciousness resulting from hemorrhagic shock grade 3 due to prolonged placenta retention for 10 days after delivery of her third child. She had an emergency hysterectomy and was sent to the intensive care unit with a hemoglobin level of 4.2 gr/dL, despite already receiving two bags of packed red blood cells during operation, and she continued with four more bags within her first day in the intensive care unit. The patient was ventilated, was supported by vasopressors, and had a low albumin level of 2.1 gr/dL. Her hemodynamic profile was difficult to stabilize, with persistent gastric residue and periodic urine output less than 1 cc/kg/hour, thereby slowing the ventilator and vasopressor weaning process. Oral supplementation of C. striata, M. oleifera, and C. xanthorrhiza was given in the second day divided in three doses every 6 hours. After the second dose, gastric residue started to subside and disappeared after the third dose. The patient's condition improved in the next 24 hours; she was extubated and discharged from the hospital in the fourth day. CONCLUSION: This is the first case report describing the effect of C. striata, M. oleifera, and C. xanthorrhiza extract in a patient with severe hemorrhagic shock due to a prolonged placenta. Accelerated recovery showed the possibility benefit of C. striata, M. oleifera, and C. xanthorrhiza extract in stabilizing oncotic pressure, neutralizing free radicals, and preventing further damage in hypoxic cells.

BACKGROUND: Traditionally, curettage has been the most widely performed surgical intervention for removing retained products of conception. However, hysteroscopic removal is increasingly performed as an alternative because of the potentially lower risk of intrauterine adhesions and higher rates of complete removal. Until recently, studies comparing curettage with hysteroscopic removal regarding reproductive and obstetrical outcomes were limited, and data conflicting. OBJECTIVE: This study aimed to assess reproductive and obstetrical outcomes in women wishing to conceive after removal of retained products of conception by hysteroscopy or ultrasound-guided electric vacuum aspiration. STUDY DESIGN: This was a prospective long-term follow-up study, conducted in 3 teaching hospitals and 1 university hospital. Patients were included from April 2015 until June 2022 for follow-up, either in a randomized controlled, nonblinded trial on the risk of intrauterine adhesions after removal of retained products of conception, or in a cohort alongside the randomized trial. Women with an ultrasonographic image suggestive of retained products of conception ranging from 1 to 4 cm were eligible. Surgical procedures in the randomized controlled trial were hysteroscopic morcellation or ultrasound-guided electric vacuum aspiration. In the cohort study, hysteroscopic treatment included hysteroscopic morcellation or cold loop resection compared with ultrasound-guided electric vacuum aspiration. RESULTS: A total of 261 out of 305 patients (85.6%) were available for follow-up after removal of retained products of conception, resulting in a cohort of 171 women after hysteroscopic removal and 90 women after removal by ultrasound-guided vacuum aspiration. Respectively, 92 of 171 women (53.8%) in the hysteroscopic removal group and 56 of 90 (62.2%) in the electric vacuum aspiration group wished to conceive (P=.192). Subsequent pregnancy rates were 88 of 91 (96.7%) after hysteroscopic removal and 52 of 56 (92.9%) after electric vacuum aspiration (P=.428). The live birth rates were 61 of 80 (76.3%) and 37 of 48 (77.1%) after hysteroscopic removal and electric vacuum aspiration, respectively (P=.914), with 8 of 88 pregnancies (9.1%) in the hysteroscopic removal group and 4 of 52 (7.7%) in the electric vacuum aspiration group still ongoing at follow-up (P=1.00). The median time to conception was 8.2 weeks (interquartile range, 5.0-17.2) in the hysteroscopic removal group and 6.9 weeks (interquartile range, 5.0-12.1) in the electric vacuum aspiration group (P=.262). The overall placental complication rate was 13 of 80 (16.3%) in the hysteroscopic removal group and 11 of 48 (22.9%) in the electric vacuum aspiration group (P=.350). CONCLUSION: Hysteroscopic removal and ultrasound-guided electric vacuum aspiration of retained products of conception seem to have no significantly different effects on subsequent live birth rate, pregnancy rate, time to conception, or pregnancy complications. Reproductive and obstetrical outcomes after removal of retained products of conception are reassuring, albeit with a high risk of placental complications.

BACKGROUND: Uterine sacculation refers to a temporary pouch or sac within the uterus that may contain the placenta or fetal parts and that may be diagnosed antepartum or after delivery. There is very limited published information about this rare condition and its management. CASES: We report two cases of uterine sacculation with entrapped placenta diagnosed immediately postpartum, managed with two different approaches. In one case, the patient underwent immediate laparotomy and placental extraction. In the second case, the patient was managed conservatively but ultimately developed signs of infection and underwent laparotomy. CONCLUSION: Uterine sacculation with entrapped placenta is a rare condition that is a potential etiology of retained placenta. Obstetric clinicians should be aware of this diagnosis and the management strategies available.

Pregnancy course depends on the appropriate connection between the mother and the developing foetus. Pregnancy is completed when the placenta is timely expelled. Placental retention is one of the possible pregnancy complications. Extracellular matrix, including adhesive proteins and enzymes that can break down collagens, seems to be responsible for it. The aim of the present study was to examine the impact of one of the adhesive proteins - glycodelin (Gd) - on selected metalloproteinases degrading collagens (MMP2, MMP3, MMP7). Placental tissues from healthy pregnant cows collected during early-mid pregnancy (2nd month n = 7, 3rd month n = 8, 4th month n = 6) and in cows that properly released placenta (NR; n = 6) and cows with retained foetal membranes (R; n = 6) were experimental material. The concentrations of glycodelin and protein content of selected metalloproteinases were measured by ELISA in the maternal and foetal placental homogenates as well as in the culture of epithelial cells derived from the maternal part of the placenta. The presence of these protein molecules was confirmed by Western Blotting. In the bovine placenta, the concentrations of examined proteins exhibit significant changes during placental formation. Gd, MMP3 and MMP7 concentrations decrease with pregnancy progress (between the 2nd and 4th month), while MMP2 concentrations were on the same level in this period. During parturition, concentrations of Gd and MMP3 were significantly higher in the R group compared to the NR group. In parallel, MMP2 concentrations did not show significant differences between the groups (NR vs R), and MMP7 concentrations decreased significantly in the maternal part of the placenta in cows with retained foetal membranes (R). Obtained results show correlations between the gestational age and proteins' (Gd, MMP3, MMP7) concentration, both in the maternal and foetal part of the placenta.

OBJECTIVES: To evaluate the occurrence of retained products of conception (RPOC) after termination of pregnancy in the first trimester and to assess the vascular signals with transvaginal ultrasonography (TVUS) examination in the detection of retained products. METHODS: A retrospective cohort study was performed using TVUS examination in patients following termination of pregnancy. In cases of RPOC, 3 scales of vascular signal were identified: type 1, no or small amount, spot flow signals; type 2, medium amount, strip-like flow signals; type 3, rich amount, circumferential-like flow signals. The correlation between vascular signals and placenta accreta spectrum (PAS) staging was proposed by sonography and histopathology findings. RESULTS: The 3 vascular patterns were differently distributed within non-RPOC as well as RPOC patients with and without PAS: type 1 vascular signal detection rates of non-RPOC and RPOC were 97.8% (262/268) and 28.1% (18/64), respectively. Of 64 cases of RPOC, 48.4% (31/64) of the patients had type 2 vascular signals. Vascular signals were enhanced in RPOC with PAS patients whose diagnosis was confirmed by histopathology. CONCLUSIONS: The vascularity (amount of flow), vascular pattern (spot, strip- or circumferential-like flow), and the flow penetrating myometrium were significant findings for distinguishing concomitant RPOC with and without PAS. Additionally, RPOC may contribute to PAS progression, or PAS and RPOC in coordination strengthen the observed vascular signals.

During pregnancy, it is necessary to create appropriate conditions for the development of the placenta and the fetus. However, during parturition, the placenta must be separated and subsequently removed as soon as possible to not expose the female to the possibility of infection. In this study, the relationship between thrombospondin-1 (THBS1) and transforming growth factor beta1 (TGFß1) concentrations was described during bovine pregnancy (second, fourth, and sixth months; n = 3/each month), at normal parturition (NR) and parturition with fetal membrane retention (R). The presence of THBS1 and TGFß1 was confirmed in bovine placental tissues of both maternal and fetal parts. Enzyme-linked immunosorbent assay showed statistically significant differences (p < 0.05) in THBS1 concentrations (pg/mg protein) between examined parturient samples (maternal part: 5.76 ± 1.61 in R vs. 2.26 ± 1.58 in NR; fetal part: 2.62 ± 1.94 in R vs. 1.70 ± 0.23 in NR). TGFß1 concentrations (pg/mg protein) were significantly lower (p < 0.05) in the retained fetal membranes compared to the released fetal membranes in the maternal part of the placenta (26.22 ± 7.53 in NR vs. 17.80 ± 5.01 in R). The participation of THBS1 in the activation of TGFß1 in parturient bovine placental tissues leading to the normal release of fetal membranes may be suggested.

The objective of the present study was to evaluate the effect of 2 dosages of prepartum cholecalciferol injection on blood minerals, vitamin D metabolites, and milk production. Cows entering their second or greater lactation (n = 158) were randomly assigned to a control group (CON) or one of 2 treatment groups receiving either 6 × 106 IU (6VitD) or 12 × 106 IU (12VitD) cholecalciferol intramuscularly on d 275 ± 1.2 (SD) of gestation. Concentrations of serum total Ca (tCa), phosphate, and Mg were determined on 1, 2, 3, 5, 7, and 10 d in milk (DIM). For a subsample of 30 cows entering the third lactation (n = 10/group), these samples were analyzed for cholecalciferol, 25-hydroxycholecalciferol (25-OHD3), and 24,25-dihydroxycholecalciferol (24,25-[OH]2D3). In these cows, we also determined 1,25-dihydroxycholecalciferol (1,25-[OH]2D3), the biologically most active metabolite, on 1, 2, 3, and 5 DIM. Repeated measures ANOVA was performed to evaluate the effect of different dosages of cholecalciferol on blood minerals, vitamin D metabolites, and milk yield over the first 5 test days after calving. Binary outcomes such as retained placenta and metritis were analyzed using a chi-squared test. Although the 12VitD treatment increased tCa concentrations on 1, 2, and 3 DIM compared with CON, administration of 6VitD increased tCa concentrations only on 1 DIM. Compared with CON cows and 6VitD cows, 12VitD cows had greater serum phosphate concentration during the first 10 DIM. Furthermore, 6VitD cows had greater serum phosphate concentrations compared with CON cows. On the contrary, 12VitD cows had lower serum Mg concentrations during the first 10 DIM compared with CON and 6VitD cows. Cholecalciferol was increased by the treatment and decreased quickly until 10 DIM. In respect to 25-OHD3, the 6VitD treatment resulted in a 4.1-fold increase in comparison to the CON group, while a 6.5-fold increase was observed in 12VitD animals. The vitamin D metabolite 24,25-(OH)2D3 increased linearly with 25-OHD3 serum levels, resulting in the highest concentrations in the 12VitD group. An increase of 1,25-(OH)2D3 until 3 DIM was observed in all cows. However, this rise was most pronounced in the CON group. The incidence of retained placenta was 1.9%, 11.5%, and 29.6%, and that of metritis was 11.5%, 15.4%, and 31.5% for CON, 6VitD, and 12VitD cows, respectively. Although none of the treated cows exerted clinical signs of hypocalcemia, one cow in CON incurred clinical hypocalcemia. Cows of the 12VitD group had a lower milk yield over the first 5 monthly test days compared with the control and 6VitD group (42.2 ± 0.5, 42.0, ± 0.5 and 40.7 ± 0.5 kg for control cows, 6VitD cows and 12VitD cows, respectively). Although no negative side effects were observed in 6VitD cows, we do not recommend the general application of 6 × 106 IU cholecalciferol before calving as positive effects on calcium homeostasis were marginal and restricted to the first DIM. The present findings confirm that the application of 12 × 106 IU cholecalciferol negatively affected milk production on this farm.

OBJECTIVES: To evaluate first-trimester ultrasound imaging of eccentric implantation in predicting the probability of retained placenta. METHODS: A total of 61 cases with gestational sac eccentrically implanted in first-trimester ultrasound imaging was selected. Demographic and obstetric data were collected through data extraction of the electronic medical record at the time of delivery admission. Baseline characteristics (including age, gestational age of first-trimester ultrasound, size of gestational sac, gestational age of delivery), delivery outcomes (mode of delivery, retained placenta or placental fragments, blood loss, postpartum hemorrhage and postpartum ultrasound imaging) were collected and analyzed. RESULTS: The risk difference for a woman with eccentric implantation to have a retained placenta was -0.18 (95% CI -0.28 to -0.08, p = 0.000) and the incidence of retained placenta in the study group was higher than in the control group (18% vs. 0%, p = 0.006). First-trimester ultrasound imaging of eccentric implantation was also found to be an independent risk factor for the incidence of inhomogeneous mass in postpartum ultrasound imaging (27.9% vs. 10.8%, adjusted OR 0.19, 95% CI 0.05 to 0.79, p = 0.012). Though 2 cases in the study group suffered postpartum hemorrhage, the risk difference for a woman with eccentric implantation to suffer postpartum hemorrhage was -0.03 (95% CI -0.08 to -0.01, not significant) and eccentric implantation did not increase postpartum hemorrhage rates (3.3% vs. 0%, not significant). CONCLUSIONS: First-trimester ultrasound imaging of eccentric implantation was associated with an increased risk of retained placenta and inhomogeneous mass in postpartum ultrasound imaging.

BACKGROUND: Retained placenta is a concern during labor and delivery. However, recent data regarding the profiles of retained placenta are scarce, especially nationwide and in minority populations. This study aimed to investigate the recent incidence of retained placenta and its associated outcomes. METHODS: We retrospectively analyzed an American population-based data from the National Inpatient Sample (NIS) 2016-2019. The outcomes of interest included the incidence of retained placenta, in-hospital mortality, length of hospital stay, and hospitalization costs. We estimated the incidence for retained placenta overall and by racial and ethnic subgroups, utilizing survey weights standardized for each subgroup. Multivariable linear or logistic regression models were employed in our study to investigate the associations between retained placenta and the impact of in-hospital mortality, duration of stay, and hospitalization expenditures for the entire population and further stratified by race and ethnicity, adjusting for potential confounders. RESULTS: Of the 13,848,131 deliveries, there were 108,035 (or 0.78%) birthing persons were identified as having retained placentas. Over time, the incidence of retained placenta increased from 730 per 100,000 (0.73%) in 2016 to 856 per 100,000 (0.86%) in 2019. Native American mothers have the highest rate of retained placenta, with a prevalence almost twice that of the general population, reaching 1,434 cases per 100,000 (1.43%). After adjusting for confounding factors, Native American mothers were more likely to have retained placenta (odds ratio [OR], 1.56; 95% confidence interval [CI], 1.35-1.81), whereas Black (OR, 0.92; 95% CI, 0.88-0.97) and Hispanic mothers (OR, 0.84; 95% CI, 0.80-0.89) were significantly less likely to have retained placenta than White mothers. Furthermore, those who delivered with a retained placenta were significantly associated with higher in-hospital mortality, a longer duration of stay, and hospitalization expenditures, which were disproportionately varied by maternal race and ethnicity. CONCLUSIONS: The incidence of retained placenta among people undergoing vaginal delivery is exhibiting an upward trend over time, with notable variations observed across different ethnic groups by unclear mechanisms. The ramifications of these findings have the potential to impact the clinical management of maternal health care and the creation of health policies, specifically in relation to the Native American birth population.

BACKGROUND: To date, the association between retained placenta and treatment success rate of misoprostol for early pregnancy failure has yet to be evaluated. The aim of this study was to evaluate this association and further investigated the connection between medical, clinical and sonographic parameters and treatment success. METHODS: We conducted a retrospective cohort study of women with early pregnancy failure treated with misoprostol from 2006 to 2021. The success rate of misoprostol treatment was compared between patients with history of retained placenta including women who underwent manual lysis of the placenta following delivery or patients who were found to have retained products of conception during their post-partum period (study group) and patients without such history (controls). Demographic, clinical, and sonographic characteristics as well as treatment outcomes were compared between the groups. RESULTS: A total of 271 women were included in the study (34 women in the study group compared to 237 women in the control group). Two-hundred and thirty-three women (86.0%) presented with missed abortion, and 38 (14.0%) with blighted ovum. Success rates of misoprostol treatment were 61.8% and 78.5% for the study and control groups, respectively (p = 0.032). Univariate analysis performed comparing successful vs. failed misoprostol treatment showed advanced age, gravidity, parity and gestational sac size (mm) on TVUS were associated with higher misoprostol treatment failure rate. Following a multivariate logistic regression model these variables did not reach statistical significance. CONCLUSION: Women who have an event of retained placenta following childbirth appear to have decreased success rate of treatment with misoprostol for early pregnancy failure. Larger studies are needed to confirm this finding.

OBJECTIVE: Postpartum retained products of conception (RPOC) can cause short- and long-term complications. Diagnosis is based on ultrasound examination and treated with hysteroscopy. This study evaluated the size of RPOC that can be related to a positive pathology result for residua. MATERIALS AND METHODS: This retrospective cohort study included women who underwent hysteroscopy for postpartum RPOC diagnosed by ultrasound, 4/2014-4/2022. Demographics, intrapartum, sonographic, intraoperative, and post-operative data were retrieved. We generated a ROC curve and found 7 mm was the statistically sonographic value for positive pathology for RPOC. Data between women with sonographic RPOC ≤ 7 mm and > 7 mm were compared. Positive and negative predictive values were calculated for RPOC pathology proved which was measured by ultrasound. RESULTS: Among 212 patients who underwent hysteroscopy due to suspected RPOC on ultrasound, 20 (9.4%) women had residua ≤ 7 mm and 192 (90.6%) had residua > 7 mm. The most common complaint was vaginal bleeding in 128 cases (60.4%); more so in the residua > 7 mm group (62.5% vs. 40%, p = .05). Among women with residua ≤ 7 mm, the interval from delivery to hysteroscopy was longer (117.4 ± 74.7 days vs. 78.8 ± 68.8 days, respectively; p = .02). Positive pathology was more frequent when residua was > 7 mm. PPV for diagnosis of 7 mm RPOC during pathology examination was 75.3% and NPV 50%. CONCLUSIONS: Sonographic evaluation after RPOC showed that residua > 7 mm was statistically correlated with positive RPOC in pathology and PPV of 75% and NPV of 50%. Due to the high NPV and low complication rate of office hysteroscopy, clinicians should consider intervention when any RPOC are measured during sonographic examination to reduce known long-term complications.

Measuring facility readiness to manage basic obstetric emergencies is a critical step toward reducing persistently elevated maternal mortality ratios (MMR). Currently, the Signal Functions (SF) is the gold standard for measuring facility readiness globally and endorsed by the World Health Organization. The presence of tracer items classifies facilities' readiness to manage basic emergencies. However, research suggests the SF may be an incomplete indicator. The Clinical Cascades (CC) have emerged as a clinically-oriented alternative to measuring readiness. The purpose of this study is to determine Amhara's clinical readiness and quantify the relationship between SF and CC estimates of readiness. Data were collected in May 2021via Open Data Kit (ODK) and KoBo Toolbox. We surveyed 20 hospitals across three levels of the health system. Commodities were used to create measures of SF-readiness (e.g., % tracers) and CC-readiness. We calculated differences in SF and CC estimates and calculated readiness loss across six emergencies and 3 stages of care in the cascades. The overall SF estimate for all six obstetric emergencies was 29.6% greater than the estimates using the CC. Consistent with global patterns, hospitals were more prepared to provide medical management (70.0% ready) compared to manual procedures (56.7% ready). The SF overestimate was greater for manual procedures 33.8% overall for retained placenta and incomplete abortion) and less for medical treatments (25.3%). Hospitals were least prepared to manage retained placentas (30.0% of facilities were ready at treatment and 0.0% were ready at monitor and modify) and most prepared to manage hypertensive emergencies (85.0% of facilities were ready at the treatment stage). When including protocols in the analysis, no facilities were ready to monitor and modify the initial therapy when clinically indicated for 3 common emergencies-sepsis, post-partum hemorrhage and retained placentas. We identified a significant discrepancy between SF and CC readiness classifications. Those facilities that fall within this discrepancy are unprepared to manage common obstetric emergencies, and employees in supply management may have difficulty identify the need. Future research should explore the possibility of modifying the SF or replacing it with a new readiness measurement.

Umbilical cord drainage involves releasing the cord clam from the umbilical cord after separation of the newborn from the maternal end of the umbilical cord. Consequently, there is emptying of blood from the placenta. This procedure is part of the active management of the third stage of labor (TSL). OBJECTIVE: This study is intended to provide knowledge about the duration of TSL and the risk of retention of the placenta using umbilical cord drainage and the no-drainage procedure. MATERIALS AND METHODS: A prospective randomized study of the management of the third stage of labor in 600 patients. The patients were equally divided into two groups with umbilical cord drainage (300) and without umbilical cord drainage (300). TSL was actively managed by FIGO (the International Federation of Gynecology and Obstetrics) recommendations. We monitored the duration of TSL and retention of the placenta after a 30 min period. RESULTS: The mean duration of TSLwas 6.8 ± 0.4 min in the drainage group and 11.6 ± 0.8 min in the control group. We conclude that umbilical cord drainage significantly shortens the duration of TSL (P = 0.026) as well as reduces the risk of placental retention. In a group where we use the drainage of the umbilical cord, placental retention 30 min after delivery of the fetus occurred in four cases while the second set occurred in 14 cases (RR 3.62; 95% CI 1.18-11.14). CONCLUSION: We assume that during umbilical cord drainage, the collapse of thin-walled uteroplacental vessels occurs earlier causing bleeding from these vessels between the placenta and the uterine wall, and therefore, earlier separation of the placenta occurs. Of course, the drainage of the umbilical cord is only one step in the algorithm of active management at the third stage of labor according to FIGO.
