RESUMEN

BACKGROUND: Obstructed labor (OL) and uterine rupture (UR) are common obstetric complications. This study explored the burden, risk factors, decomposition, and health inequalities associated with OL and UR to improve global maternal health. METHODS: This was a cross-sectional analysis study including data on OL and UR from the Global Burden of Diseases, and Risk Factors Study (GBD) 2019. The main outcome measures included the number and age-standardized rate (ASR) of incidence, disability-adjusted life years (DALYs), prevalence, and deaths. RESULTS: The global burden of OL and UR has declined, with a decrease in incidence (number in 2019: 9,410,500.87, 95%UI 11,730,030.94 to 7,564,568.91; ASR in 2019: 119.64 per 100,000, 95%UI 149.15 to 96.21; estimated annual percentage change [EAPC] from 1990 to 2019: -1.34, 95% CI -1.41 to -1.27) and prevalence over time. However, DALYs (number in 2019: 999,540.67, 95%UI 1,209,749.35 to 817,352.49; ASR in 2019: 12.92, 95%UI 15.63 to 10.56; EAPC from 1990 to 2019: -0.91, 95% CI -1.26 to -0.57) and deaths remain significant. ASR of DALYs increased for the 10-14 year-old age group (2.01, 95% CI 1.53 to 2.5), the 15-19 year-old age group (0.07, 95% CI -0.47 to 0.61), Andean Latin America (3.47, 95% CI 3.05 to 3.89), and Caribbean (4.16, 95% CI 6 to 4.76). Iron deficiency was identified as a risk factor for OL and UR, and its impact varied across different socio-demographic indices (SDIs). Decomposition analysis showed that population growth primarily contributed to the burden, especially in low SDI regions. Health inequalities were evident, the slope and intercept for DALYs were - 47.95 (95% CI -52.87 to -43.02) and - 29.29 (95% CI -32.95 to -25.63) in 1990, 39.37 (95%CI 36.29 to 42.45) and 24.87 (95%CI 22.56 to 27.18) in 2019. Concentration indices of ASR-DALYs were - 0.2908 in 1990 and - 0.2922 in 2019. CONCLUSION: This study highlights the significant burden of OL and UR and emphasizes the need for continuous efforts to reduce maternal mortality and morbidity. Understanding risk factors and addressing health inequalities are crucial for the development of effective interventions and policies to improve maternal health outcomes globally.

RESUMEN

BACKGROUND: Conjoined twins (CT), which used to be historically defined as "monstrous human" and previously so-called Siamese twins in the early eighteenth century, are one of the very rare congenital malformations with an uncertain etiology and complex yet remain inconclusively debatable regarding its pathophysiological mechanisms of fusion and fission theories. Among all types of CT, parasitic CT, especially the pygopagus sub-type, is exceedingly rarer. To the best of the authors' knowledge, no parasitic CT had been reported in Papua, and this is the first finding in South Papua. CASE REPORT: Herein, a 30-year-old multigravida female with 37th-week gestation, previous twice spontaneous miscarriage, and non-adequate antenatal care history is presented with a chief complaint of painful construction and greenish fluid leakage from the vagina, with an examination that showed a cephalic presentation with a "peculiar" big mass at the upper uterus and complete cervical dilation toward second-stage inpartu. Vaginal delivery was performed with a complication of obstructed labor due to uncommon dystocia with a suspected "big mass" below the fetal buttocks and intrapartum dead. Intrapartum transabdominal ultrasound demonstrates a gross anatomically like an organ inside a fluid-filled mass with unidentified parts, leading to a suspected type of congenital malformation at the baby's sacral region. Emergency C-section was done with findings of parasitic pygopagus CT, showing an attachment of a large irregular fluid-filled mass-like incomplete twin (parasite) with palpable soft tissue and bony structure inside to the buttocks of a male autosite twin, and an additional third leg which happened to be an under-developed lower extremity with a sacrum-like structure. CONCLUSIONS: An obstetrician's routine ANC and critical radiological evaluation will increase the odds of identifying CT or other congenital malformations to provide better delivery planning or further management. Increasing maternal health knowledge in society, improving medical skills and knowledge levels for health providers, and advancing supporting facilities and specialists are future strategies for managing and preventing such cases in low-middle-income countries.

RESUMEN

BACKGROUND: Female genital fistula is a traumatic debilitating injury, frequently caused by prolonged obstructed labor, affecting between 500,000-2 million women in lower-resource settings. Vesicovaginal fistula causes urinary incontinence, and other morbidity may occur during fistula development. Women with fistula are stigmatized, limit social and economic engagement, and experience psychiatric morbidity. Improved surgical access has reduced fistula consequences yet post-repair risks impacting quality of life and well-being include fistula repair breakdown or recurrence and ongoing or changing urine leakage or incontinence. Limited evidence on risk factors contributing to adverse outcomes hinders interventions to mitigate adverse events. This study aims to quantify these adverse risks and inform clinical and counseling interventions to optimize women's health and quality of life following fistula repair through: identifying predictors and characteristics of post-repair fistula breakdown and recurrence (Objective 1) and post-repair incontinence (Objective 2), and to identify feasible and acceptable intervention strategies (Objective 3). METHODS: This mixed-methods study incorporates a prospective cohort of women with successful vesicovaginal fistula repair at approximately 12 fistula repair centers in Uganda (Objectives 1-2) followed by qualitative inquiry among key stakeholders (Objective 3). Cohort participants will have a baseline visit at the time of surgery followed by data collection at 2 weeks, 6 weeks, 3 months and quarterly thereafter for 3 years. Primary predictors to be evaluated include patient-related factors, fistula-related factors, fistula repair-related factors, and post-repair behaviors and exposures, collected via structured questionnaire at all data collection points. Clinical exams will be conducted at baseline, 2 weeks post-surgery, and for outcome confirmation at symptom development. Primary outcomes are fistula repair breakdown or fistula recurrence and post-repair incontinence. In-depth interviews will be conducted with cohort participants (n ~ 40) and other key stakeholders (~ 40 including family, peers, community members and clinical/social service providers) to inform feasibility and acceptability of recommendations. DISCUSSION: Participant recruitment is underway. This study is expected to identify key predictors that can directly improve fistula repair and post-repair programs and women's outcomes, optimizing health and quality of life. Furthermore, our study will create a comprehensive longitudinal dataset capable of supporting broad inquiry into post-fistula repair health. Trial Registration ClinicalTrials.gov Identifier: NCT05437939.


Female genital fistula is a traumatic birth injury which occurs where access to emergency childbirth care is poor. It causes uncontrollable urine leakage and is associated with other physical and psychological symptoms. Due to the urine leakage and its odor, women with fistula are stigmatized which has mental health and economic consequences. Ensuring women's access to fistula surgery and ongoing wellbeing is important for limiting the impact of fistula. After fistula surgery, health risks such as fistula repair breakdown or recurrence or changes to urine leakage can happen, but studies during this time are limited. Our study seeks to measure these health risks and factors influencing these risks quantitatively, and work with patients, community members, and fistula care providers to come up with solutions. We will recruit up to 1000 participants into our study at the time of fistula surgery and follow them for three years. We will collect data on patient sociodemographic characteristics, clinical history, and behavior after fistula repair through patient survey and medical record review. If participants have changes in urine leakage, they will be asked to return to the fistula repair hospital for exam. We will interview about 80 individuals to obtain their ideas for feasible and acceptable intervention options. We expect that this study will help to understand risk factors for poor health following fistula repair and, eventually, improve women's health and quality of life after fistula.

RESUMEN

BACKGROUND: The prevalence and impact of fistulas are more common in developing countries with limited access to emergency obstetric care. As a result, women in these settings often experience adverse psychosocial factors. The purpose of this study was to describe the characteristics of Congolese women who developed urogenital fistula following Cesarean sections (CS) to determine the characteristics associated with two etiologies: (1) prolonged obstructed labor; and (2) a complication of CS following obstructed labor. METHODS: We performed a cross-sectional study on abstracted data from all patients with urogenital fistula following CS who received care during a surgical campaign in a remote area of the Democratic Republic of the Congo (DRC). Descriptive analyses characterized patients with fistula related to obstructed labor versus CS. Univariate and multivariate logistic regression models identified factors associated with obstetric fistula after cesarean delivery following obstructed labor. Variables were included in the logistic regression models based upon biological plausibility. RESULTS: Among 125 patients, urogenital fistula etiology was attributed to obstructed labor in 77 (62%) and complications following CS in 48 (38%). Women with a fistula, attributed to obstructed labor, developed the fistula at a younger age (p = .04) and had a lower parity (p = .02). Attempted delivery before arriving at the hospital was associated with an increased risk of obstetric fistula after cesarean delivery following obstructed labor (p < .01). CONCLUSION: CS are commonly performed on women who arrive at the hospital following prolonged obstructed labor and fetal demise, and account for almost 40% of urogenital fistula. Obstetric providers should assess maternal status upon arrival to prevent unnecessary CS and identify women at risk of developing a fistula.

RESUMEN

It is estimated that one million women worldwide live with untreated fistula, a devastating injury primarily caused by prolonged obstructed labor when women do not have access to timely emergency obstetric care. Women with fistula are incontinent of urine and/or feces and often suffer severe social and psychological consequences, such as profound stigma and depression. Obstetric fistula affects economically vulnerable women and garners little attention on the global health stage. Exact figures on fistula incidence and prevalence are not known. In Kenya, results from a 2014 population-based survey suggest that 1% of reproductive-aged women have experienced fistula-like symptoms. In collaboration with key stakeholders, Fistula Foundation launched the Fistula Treatment Network (initially known as Action on Fistula) in 2014 to increase access to timely, quality fistula treatment and comprehensive post-operative care for women with fistula in Kenya. The integrated model built linkages between the community and the health system to support women through all parts of their treatment journey and to build capacity of healthcare providers and community leaders who care for these women. Fistula Foundation and its donors provided the program's funding. Seed funding, representing about 30% of the program budget, was provided by Astellas Pharma EMEA.Over the six-year period from 2014 to 2020, the network supported 6,223 surgeries at seven hospitals, established a fistula training center, trained eleven surgeons and 424 Community Health Volunteers, conducted extensive community outreach, and contributed to the National Strategic Framework to End Female Genital Fistula. At 12 months post fistula repair, 96% of women in a community setting reported that they were not experiencing any incontinence and the proportion of women reporting normal functioning increased from 18% at baseline to 85% at twelve-months.The Fistula Treatment Network facilitated collaboration across hospital and community actors to enhance long-term outcomes for women living with fistula. This model improved awareness and reduced stigma, increased access to surgery, strengthened the fistula workforce, and facilitated post-operative follow-up and reintegration support for women. This integrated approach is an effective and replicable model for building capacity to deliver comprehensive fistula care services in other countries where the burden of fistula is high.

RESUMEN

This recommendation document follows the mission of the World Association of Perinatal Medicine in collaboration with the Perinatal Medicine Foundation. We aim to bring together groups and individuals throughout the world for standardization to implement the ultrasound evaluation in labor ward and improve the clinical management of labor. Ultrasound in labor can be performed using a transabdominal or a transperineal approach depending upon which parameters are being assessed. During transabdominal imaging, fetal anatomy, presentation, liquor volume, and placental localization can be determined. The transperineal images depict images of the fetal head in which calculations to determine a proposed fetal head station can be made.

RESUMEN

INTRODUCTION: The obstetric conjugate represents the shortest anteroposterior diameter of the birth canal and it reflects the capacity of the pelvic inlet to allow the passage and the engagement of the fetal head. The antepartum evaluation of this parameter may be attempted at digital examination to predict the risk of cephalopelvic disproportion, but the accuracy of clinical pelvimetry is notoriously poor. The aim of our study was to describe the sonographic measurement of the obstetric conjugate at transabdominal 2D-ultrasound and to assess its reproducibility. MATERIAL AND METHODS: This is a prospective cohort study conducted at a tertiary University hospital. A non-consecutive series of pregnant women with uncomplicated singleton pregnancies attending the antenatal clinic for routine booking from 34 weeks of gestation onward were included. The ultrasound probe was longitudinally placed above the level of the symphysis and the interpubic fibrocartilaginous disk was visualized. Then the promontory was identified as the most prominent segment of the sacral vertebral column. The obstetric conjugate was measured as the distance between the inner edge of the interpubic disk and the promontory. The inter- and intraobserver repeatability of this measurement was calculated using the intraclass correlation coefficient (ICC) and the Bland-Altman method. RESULTS: In all, 119 women were considered eligible for the study; of these, 111/119 (93.3%) women were included in the analysis with a median gestational age of 36.0 (35.0-37.0) weeks. The mean obstetric conjugate measurement was 11.4 ± 0.93 mm for the first operator and 11.4 ± 0.91 mm for the second operator. The overall interobserver ICC was 0.95 (95% [confidence interval] CI 0.92-0.96) and the overall intraobserver ICC was 0.97 (95% CI 0.96-0.98). Limits of agreement ranged from -0.84 to 0.80 for interobserver measures and from -0.64 to 0.62 for intraobserver measures. The degree of reliability was also analyzed for women with a body mass index ≥30 and for women with a gestational age ≥37 weeks. The inter- and intraobserver ICCs were respectively 0.97 (95% CI 0.90-0.98) and 0.98 (0.95-0.99) in the former group and 0.96 (95% CI 0.93-0.98) and 0.97 (95% CI 0.95-0.98) in the latter group. CONCLUSIONS: Our study demonstrated that among pregnant women at term gestation, sonographic measurement of the obstetric conjugate is feasible and reproducible.

RESUMEN

BACKGROUND: Obstructed labor is a preventable obstetric complication. However, it is an important cause of maternal mortality and morbidity and of adverse outcomes for newborns in resource-limited countries in which undernutrition is common resulting in a small pelvis in which there is no easy access to functioning health facilities with a capacity to carry out operative deliveries. Therefore, this systematic review and meta-analysis aimed to estimate the incidence, causes, and maternofetal outcomes of obstructed labor among mothers who gave birth in Ethiopia. METHOD: for this review, we used the standard PRISMA checklist guideline. Different online databases were used for the review: PubMed, Google Scholar, EMBASE, Cochrane Library, HINARI, AFRO Library Databases, and African Online Journals. Based on the adapted PICO principles, different search terms were applied to achieve and access the essential articles. The search included all published and unpublished observational studies written only in the English language and conducted in Ethiopia. Microsoft Excel 16 was used for data entrance, and Stata version 11.0 (Stata Corporation, College Station, Texas, USA) was used for data analysis. RESULTS: I included sixteen (16) primary studies with twenty-eight thousand five hundred ninety-one (28,591) mothers who gave birth in Ethiopia. The pooled incidence of obstructed labor in Ethiopia was 12.93% (95% CI: 10.44-15.42, I2 = 98.0%, p < 0.001). Out of these, 67.3% (95% CI: 33.32-101.28) did not have antenatal care follow-up, 77.86% (95% CI: 63.07-92.66) were from the rural area, and 58.52% (95% CI: 35.73- 82.31) were referred from health centers and visited hospitals after 12 h of labor. The major causes of obstructed labor were cephalo-pelvic disproportion 64.65% (95% CI: 57.15- 72.14), and malpresentation and malposition in 27.24% (95% CI: 22.05-32.42) of the cases. The commonest complications were sepsis in 38.59% (95% CI: 25.49-51.68), stillbirth in 38.08% (95% CI: 29.55-46.61), postpartum hemorrhage in 33.54% (95% CI:12.06- 55.02), uterine rupture in 29.84% (95% CI: 21.09-38.58), and maternal death in 17.27% (95% CI: 13.47-48.02) of mothers who gave birth in Ethiopia. CONCLUSION: This systematic review and meta-analysis showed that the incidence of obstructed labor was high in Ethiopia. Not having antenatal care follow-up, rural residency, and visiting hospitals after 12 h of labor increased the incidence of obstructed labor. The major causes of obstructed labor were cephalo-pelvic disproportion, and malpresentation and malpresentation. Additionally, the commonest complications were sepsis, stillbirth, postpartum hemorrhage, uterine rupture, and maternal death. Thus, promoting antenatal care service utilization, a good referral system, and availing comprehensive obstetric care in nearby health institutions are recommended to prevent the incidence of obstructed labor and its complications.

RESUMEN

Recently, we presented the cliff-edge model to explain the evolutionary persistence of relatively high incidences of fetopelvic disproportion (FPD) in human childbirth. According to this model, the regular application of Caesarean sections since the mid-20th century has triggered an evolutionary increase of fetal size relative to the dimensions of the maternal birth canal, which, in turn, has inflated incidences of FPD. While this prediction is difficult to test in epidemiological data on Caesarean sections, the model also implies that women born by Caesarean because of FPD are more likely to develop FPD in their own childbirth compared with women born vaginally. Multigenerational epidemiological studies indeed evidence such an intergenerational predisposition to surgical delivery. When confined to anatomical indications, these studies report risks for Caesarean up to twice as high for women born by Caesarean compared with women born vaginally. These findings provide independent support for our model, which we show here predicts that the risk of FPD for mothers born by Caesarean because of FPD is 2.8 times the risk for mothers born vaginally. The congruence between these data and our prediction lends support to the cliff-edge model of obstetric selection and its underlying assumptions, despite the genetic and anatomical idealizations involved.

RESUMEN

The strikingly high incidence of obstructed labor due to the disproportion of fetal size and the mother's pelvic dimensions has puzzled evolutionary scientists for decades. Here we propose that these high rates are a direct consequence of the distinct characteristics of human obstetric selection. Neonatal size relative to the birth-relevant maternal dimensions is highly variable and positively associated with reproductive success until it reaches a critical value, beyond which natural delivery becomes impossible. As a consequence, the symmetric phenotype distribution cannot match the highly asymmetric, cliff-edged fitness distribution well: The optimal phenotype distribution that maximizes population mean fitness entails a fraction of individuals falling beyond the "fitness edge" (i.e., those with fetopelvic disproportion). Using a simple mathematical model, we show that weak directional selection for a large neonate, a narrow pelvic canal, or both is sufficient to account for the considerable incidence of fetopelvic disproportion. Based on this model, we predict that the regular use of Caesarean sections throughout the last decades has led to an evolutionary increase of fetopelvic disproportion rates by 10 to 20%.

RESUMEN

INTRODUCTION AND HYPOTHESIS: The impoverished West African country of Niger has high rates of obstetric fistula. We report a 6-month postoperative follow-up of 384 patients from the Danja Fistula Center and assess factors associated with operative success or failure. METHODS: The medical records of 384 women who had completed a 6-month follow-up after fistula surgery were reviewed. Cases were categorized as "easy," "of intermediate complexity," or "difficult" based on a preoperative points system. Data were analyzed using simple chi-squared statistics and logistic regression. RESULTS: The patients were predominantly of Hausa ethnicity (73%), married young (average 15.9 years), had teenage first pregnancies (average first delivery 16.9 years), and experienced prolonged labor (average 2.3 days) with poor outcomes (89% stillbirth rate). The average parity was four. Patients commonly developed their fistula during their first delivery (43.5%), but over half sustained a fistula during a subsequent delivery (56.5%). Prior fistula surgery elsewhere (average 1.75 operations) was common. The overall surgical success ("closed and dry") was 54%. When the 134 primary operations were analyzed separately, the overall success rate was 80%. Increasing success was seen with decreasing surgical difficulty: 92% success for "easy" cases, 68% for "intermediate" cases, and 57% success for "difficult" cases. Success decreased with increasing numbers of previous attempts at surgical repair. CONCLUSIONS: These data provide further evidence that clinical outcomes are better when primary fistula repair is performed by expert surgeons in specialist centers with the support of trained fistula nurses.

RESUMEN

Fetal malpositions and cephalic malpresentations are well-recognized causes of failure to progress in labor. They frequently require operative delivery, and are associated with an increased probability of fetal and maternal complications. Traditional obstetrics emphasizes the role of digital examinations, but recent studies demonstrated that this approach is inaccurate and intrapartum ultrasound is far more precise. The objective of this review is to summarize the current body of literature and provide recommendations to identify malpositions and cephalic malpresentations with ultrasound. We propose a systematic approach consisting of a combination of transabdominal and transperineal scans and describe the findings that allow an accurate diagnosis of normal and abnormal position, flexion, and synclitism of the fetal head. The management of malpositions and cephalic malpresentation is currently a matter of debate, and individualized depending on the general clinical picture and expertise of the provider. Intrapartum sonography allows a precise diagnosis and therefore offers the best opportunity to design prospective studies with the aim of establishing evidence-based treatment. The article is accompanied by a video that demonstrates the sonographic technique and findings.

RESUMEN

INTRODUCTION AND HYPOTHESIS: We tested the null hypothesis that there were no differences between patients with obstetric fistula and parous controls without fistula. METHODS: A unmatched case-control study was carried out comparing 75 women with a history of obstetric fistula with 150 parous controls with no history of fistula. Height and weight were measured for each participant, along with basic socio-demographic and obstetric information. Descriptive statistics were calculated and differences between the groups were analyzed using Student's t test, Mann-Whitney U test where appropriate, and Chi-squared or Fisher's exact test, along with backward stepwise logistic regression analyses to detect predictors of obstetric fistula. Associations with a p value <0.05 were considered significant. RESULTS: Patients with fistulas married earlier and delivered their first pregnancies earlier than controls. They had significantly less education, a higher prevalence of divorce/separation, and lived in more impoverished circumstances than controls. Fistula patients had worse reproductive histories, with greater numbers of stillbirths/abortions and higher rates of assisted vaginal delivery and cesarean section. The final logistic regression model found four significant risk factors for developing an obstetric fistula: age at marriage (OR 1.23), history of assisted vaginal delivery (OR 3.44), lack of adequate antenatal care (OR 4.43), and a labor lasting longer than 1 day (OR 14.84). CONCLUSIONS: Our data indicate that obstetric fistula results from the lack of access to effective obstetrical services when labor is prolonged. Rural poverty and lack of adequate transportation infrastructure are probably important co-factors in inhibiting access to needed care.

RESUMEN

BACKGROUND: Obstetric fistula devastates the lives of women and is found most commonly among the poor in resource-limited settings. Unrepaired third- and fourth-degree perineal lacerations have been shown to be the source of approximately one-third of the fistula burden in fistula camps in Kenya. In this study, we assessed potential barriers to accurate identification by Kenyan nurse-midwives of these complex perineal lacerations in postpartum women. METHODS: Nurse-midwife trainers from each of the seven sub-counties of Siaya County, Kenya were assessed in their ability to accurately identify obstetric lacerations and anatomical structures of the perineum, using a pictorial assessment tool. Referral pathways, follow-up mechanisms, and barriers to assessing obstetric lacerations were evaluated. RESULTS: Twenty-two nurse-midwife trainers were assessed. Four of the 22 (18.2%) reported ever receiving formal training on evaluating third- and fourth-degree obstetric lacerations, and 20 of 22 (91%) reported health-system challenges to adequately completing their examination of the perineum at delivery. Twenty-one percent of third- and fourth-degree obstetric lacerations in the pictorial assessment were incorrectly identified as first- or second-degree lacerations. CONCLUSION: County nurse-midwife trainers in Siaya, Kenya, experience inadequate training, equipment, staffing, time, and knowledge as barriers to adequate diagnosis and repair of third- and fourth-degree perineal tears.

RESUMEN

BACKGROUND: Obstetric fistula is a debilitating and traumatic birth injury affecting 2-3 million women globally, mostly in sub-Saharan Africa and Asia. Affected women suffer physically, psychologically and socioeconomically. International efforts have increased access to surgical treatment, yet attention to a holistic outcome of post-surgical rehabilitation is nascent. We sought to develop and pilot test a measurement instrument to assess post-surgical family and community reintegration. METHODS: We conducted an exploratory sequential mixed-methods study, beginning with 16 in-depth interviews and four focus group discussions with 17 women who underwent fistula surgery within two previous years to inform measure development. The draft instrument was validated in a longitudinal cohort of 60 women recovering from fistula surgery. Qualitative data were analyzed through thematic analysis. Socio-demographic characteristics were described using one-way frequency tables. We used exploratory factor analysis to determine the latent structure of the scale, then tested the fit of a single higher-order latent factor. We evaluated internal consistency and temporal stability reliability through Raykov's ρ and Pearson's correlation coefficient, respectively. We estimated a series of linear regression models to explore associations between the standardized reintegration measure and validated scales representing theoretically related constructs. RESULTS: Themes central to women's experiences following surgery included resuming mobility, increasing social interaction, improved self-esteem, reduction of internalized stigma, resuming work, meeting their own needs and the needs of dependents, meeting other expected and desired roles, and negotiating larger life issues. We expanded the Return to Normal Living Index to reflect these themes. Exploratory factor analysis suggested a four-factor structure, titled 'Mobility and social engagement', 'Meeting family needs', 'Comfort with relationships', and 'General life satisfaction', and goodness of fit statistics supported a higher-order latent variable of 'Reintegration.' Reintegration score correlated significantly with quality of life, depression, self-esteem, stigma, and social support in theoretically expected directions. CONCLUSION: As more women undergo surgical treatment for obstetric fistula, attention to the post-repair period is imperative. This preliminary validation of a reintegration instrument represents a first step toward improving measurement of post-surgical reintegration and has important implications for the evidence base of post-surgical reintegration epidemiology and the development and evaluation of fistula programming.

RESUMEN

We report on the sonographic appearance of a new type of fetal head malposition in labor that has not been previously described systematically. In some circumstances, the fetal lie is characterized by a lateral orientation of the head with respect to the trunk and, on suprapubic ultrasound, a transverse section of the fetal chest together with the facial profile can be seen on the same image. These sonographic findings were documented in five cases of first-stage labor arrest. This report illustrates how, in these circumstances, ultrasound might be helpful in clarifying the precise cause of obstructed labor.

RESUMEN

Uterine prolapse is a rare condition in pregnancy that may lead to serious antepartum, intrapartum and postpartum complications for the mother and fetus. This is the case of a 30-year-old woman who presented at 38 weeks of gestation of her third pregnancy with spontaneous rupture of membranes and labor pain. Pelvic examination in dorsal lithotomy position revealed a stage 3 uterine prolapse, with a 3 cm dilated thick edematous cervix and rupture of membranes with clear liquor. Four hours after admission, the cervix became more edematous and there had been no change in cervical dilatation. Therefore, advanced apical prolapse (negatively affecting labor) was diagnosed, and the obstetric team decided on a cesarean delivery because a lack of progression of cervical dilatation. A live female baby weighing 3400 g was delivered and no abnormal findings or complications were reported. The patient had uneventful postoperative course with a significant reduction in uterine prolapse. Six weeks post-delivery, assessment in the urogynecology outpatient clinic revealed spontaneous resolution of the prolapse. The woman was advised to perform pelvic floor muscle exercises and to seek medical advice if the condition recurred. Obstetricians should be aware of this rare condition in pregnancy, as proper early diagnosis is crucial for a safe, uneventful pregnancy.

RESUMEN

BACKGROUND: Undernutrition refers to an overall deficiency of nutrients due to an inadequate intake of a well-balanced diet. Undernourishment during pregnancy is an important contributor to maternal morbidity and mortality. It remains a persistent problem in developing countries, where women usually fall behind men in having access to food, health care, and education. Despite the high prevalence of maternal undernourishment, its direct impact on obstetric outcomes has not been studied in developing countries, including Ethiopia. OBJECTIVE: This study aimed to assess the effect of maternal undernutrition on adverse obstetric outcomes in Gedeo zone public hospitals. METHOD: A cohort study design was employed in Gedeo zone public hospitals from June 30, 2022, to February 28, 2023. This study included 721 pregnant women, 237 were exposed group whereas 484 were non-exposed. A systematic random sampling technique was used to select a non-exposed group and the exposed group was selected consecutively. Both groups were followed for 7 months, from 16 weeks of gestation to 24 h of delivery. The pretested interviewer-administered questionnaire and checklist were used. EpiData 4.4.1.2.version was used for data entry and analyzed using Stata version 16 software. A modified Poisson regression model with robust standard errors was used to determine relative risk, and the statistical association was declared at a p-value ≤ 0.05. Finally, the findings were reported in figures, tables, and words. RESULT: The incidence of adverse obstetrics outcomes among undernourished and normally nourished mothers was hypertensive disorder during pregnancy (HDDP) (7.49% vs. 3.19%), antepartum haemorrhage (7.49% vs. 3.19%), obstructed labor (1.53% vs. 3.49%), premature rupture of the membrane (2.5% vs. 3.33%), preterm labor (6.52% vs. 6.93%), instrumental vaginal delivery (1.8% vs. 4.3%), postpartum haemorrhage (5.95% vs. 3.88%), and sepsis (3.74% vs. 1.94%). The risk of adverse obstetric outcomes among undernourished women was hypertensive disorder during pregnancy (HDDP) (aRR) = 4.07, 95%CI: 2.53-6.55), antepartum haemorrhage (APH) (aRR = 5.0, 95% CI: 2.08-12.72), preterm labor (aRR = 1.8, 95%CI: 1.23-2.62), operative delivery (aRR = 1.24, 95%C: 0.87-1.78), postpartum haemorrhage (aRR = 3.02, 95%CI: 1.91-4.79), and sepsis/chrioaminitis (aRR = 3.55, 95%CI: 1.83-6.89) times higher than normally nourished women. CONCLUSION: The incidence rates of hypertensive disorder during pregnancy (HDDP), antepartum haemorrhage, postpartum haemorrhage, and sepsis were higher among undernourished women than normally nourished women. Undernourished women during pregnancy have an increased risk of adverse obstetrics outcomes including hypertensive disorder during pregnancy, antepartum, preterm labor, operative delivery, postpartum haemorrhage, and sepsis/chorioamnionitis.

RESUMEN

The segmentation of the fetal head (FH) and pubic symphysis (PS) from intrapartum ultrasound images plays a pivotal role in monitoring labor progression and informing crucial clinical decisions. Achieving real-time segmentation with high accuracy on systems with limited hardware capabilities presents significant challenges. To address these challenges, we propose the real-time segmentation network (RTSeg-Net), a groundbreaking lightweight deep learning model that incorporates innovative distribution shifting convolutional blocks, tokenized multilayer perceptron blocks, and efficient feature fusion blocks. Designed for optimal computational efficiency, RTSeg-Net minimizes resource demand while significantly enhancing segmentation performance. Our comprehensive evaluation on two distinct intrapartum ultrasound image datasets reveals that RTSeg-Net achieves segmentation accuracy on par with more complex state-of-the-art networks, utilizing merely 1.86 M parameters-just 6 % of their hyperparameters-and operating seven times faster, achieving a remarkable rate of 31.13 frames per second on a Jetson Nano, a device known for its limited computing capacity. These achievements underscore RTSeg-Net's potential to provide accurate, real-time segmentation on low-power devices, broadening the scope for its application across various stages of labor. By facilitating real-time, accurate ultrasound image analysis on portable, low-cost devices, RTSeg-Net promises to revolutionize intrapartum monitoring, making sophisticated diagnostic tools accessible to a wider range of healthcare settings.

RESUMEN

BACKGROUND: Obstructed labor leading to a vesicovaginal fistula remains a devastating outcome of childbirth in low-resource countries. Women with an irreparable vesicovaginal fistula may be candidates for a urinary diversion, such as the Mainz II modified ureterosigmoidostomy procedure. Previous reviews state that the procedure should be considered in low-resource countries. However, given the limited duration of postoperative follow-up, these studies do not adequately represent the long-term morbidity and mortality that is likely associated with this procedure. We present data that strongly support avoiding the procedure in low-resource countries. OBJECTIVE: This study aimed to evaluate the postoperative status of the patient (dead, alive, lost to follow-up) and time to death following the Mainz II procedure. STUDY DESIGN: This is a case series including 21 patients who underwent a Mainz II urinary diversion from April 2013 to June 2015 for management of irreparable vesicovaginal fistula at the Fistula Care Centre in Lilongwe, Malawi. Patients were seen postoperatively at 3, 6, 9, and 12 months, followed by every 6 to 12 months thereafter. Descriptive statistics were performed to summarize the data. RESULTS: During the postoperative period, 8 (38.1%; 8/21) patients died, 5 (23.8%; 5/21) were lost to follow-up, and 8 (38.1%; 8/21) are currently alive and followed up at the Fistula Care Centre. We strongly suspect that 7 of the 8 deaths were related to the procedure given that the patients had illnesses that exacerbated the metabolic consequences of the procedure. The eighth patient died after being attacked by robbers. Unfortunately, the exact cause of death could not be determined for these patients. Given that most of the suspected illnesses would be treatable in an otherwise healthy patient, even in this low-resource setting, we surmised that the metabolic compromise from the Mainz II procedure likely contributed to their untimely death. The average time from procedure to death was 58 months, with the earliest death at 10 months and the most recent at 7 years after the procedure. CONCLUSION: The Mainz II procedure is an option for patients with irreparable fistula. However, it should likely not be performed in low-resource countries given the long-term complications that often cannot be adequately addressed in these settings, leading to significant morbidity and mortality.
