Intervalo de nacimiento entre gemelos como determinante del resultado neonatal precoz / Inter-twin delivery interval as a determinant of early neonatal outcome

INTRODUCCIÓN Y OBJETIVOS: La mayoría de las sociedades científicas recomiendan el parto vaginal del segundo gemelo siempre que el primer gemelo esté en presentación cefálica. En estos casos existe controversia cuánto tiempo transcurrido entre el parto de ambos es determinante en el resultado adverso del segundo gemelo. El objetivo de este estudio es examinar cómo influye dicho intervalo en el resultado perinatal precoz en nuestro Centro y el coste de las estancias neonatales y maternas. MÉTODOS: Estudio de cohortes retrospectivo entre mayo de 2014 y diciembre de 2018. Se comparó el resultado neonatal adverso estableciendo puntos de corte de intervalo entre el nacimiento de 10 y 30 minutos. Así mismo, se examinó la relación de otras variables del parto con el desenlace neonatal y se calcularon los costes de las estancias neonatales y maternas. RESULTADOS: Se incluyeron 128 partos gemelares vaginales asistidos en el Hospital Universitario Nuestra Señora de la Candelaria. Se evidenció triple tasa de resultado neonatal adverso en el grupo de más de 10 minutos (p=0,026 y OR 2,4) y tres veces peor en el de más de 30 minutos (p=0,013 y OR 6,4). Se obtuvo una correlación lineal negativa significativa entre el intervalo intergemelar y el pH umbilical. La prematuridad y el bajo peso al nacer fueron predictores de un mal desenlace neonatal. CONCLUSIONES: No parece recomendable que el intervalo intergemelar se prolongue más allá de los 30 minutos. Es seguro recomendar el parto vía vaginal en gestaciones gemelares siempre que el primero esté en presentación cefálica.

INTRODUCTION AND OBJECTIVES: Most scientific societies recommend vaginal delivery of the second twin when the first twin is in cephalic presentation. In these cases, there is controversy over how much inter-twin interval is decisive in the adverse outcome of the second twin. The aim of this study is to examine whether inter-twin delivery interval affects immediate perinatal outcome and the cost of neonatal and maternal stays. METHODS: Retrospective cohort study including 128 twin vaginal births attended in the Hospital Universitario Nuestra Señora de la Candelaria between May 2014 and December 2018. We compared the presence of composite adverse neonatal outcome by establishing interval cut-off points between birth of 10 and 30 minutes. Likewise, the relationship of other delivery associated variables with neonatal outcome was examined. Health care costs were calculated. RESULTS: There was a higher rate of composite adverse neonatal outcome in the 10 minute-group (p = 0.026, OR 2.4) and three times higher in the 30 minute-group (p = 0.013, OR 6.4). A significant negative linear correlation was obtained between birth interval and umbilical artery pH. Prematurity and low birth weight were predictors of a poor neonatal outcome. CONCLUSION: Our data suggests that inter-twin delivery interval shouldn't be prolonged beyond 30 minutes. Vaginal delivery is a safe option in twin gestations providing the first twin is in a cephalic presentation, regardless of the second twin presentation.

Calving difficulty in dairy cows has a longer effect on saleable milk yield than on estimated milk production.

A difficult calving affects the welfare of the cow and has economic implications for the farm. The degree of calving difficulty can vary from no assistance needed through a slight pull required to surgery being needed. With respect to milk production, it is not clear at which degree of calving difficulty adverse effects occur or for how long they last. Studies usually only consider the milk produced by animals who completed full lactations but the saleable milk production of the whole herd, regardless of each cow having achieved a full lactation, might be a better indicator of the productivity of the cows and the underlying stresses they experience, as well as being more representative of the real losses that producers incur. The objective of this study was to investigate how various degrees of calving difficulty would alter both the cow's milk production and their production of saleable milk over different stages of their subsequent lactation. The calving difficulty scores and the subsequent milk production were retrieved from an experimental dairy farm (in the United Kingdom) for 2 herds that contained 2,430 and 1,413 lactations. To account for milk saleable by the farmer, individual cumulative saleable milk yields, referred to as saleable milk yields (SMY), were calculated at 30, 60, 90, and 300 d in milk unconditional on the animal having achieved the lactation stage of interest. Lactation SMY were obtained based on the real lactation length achieved by the animal. Mean daily milk yields were also calculated for the same lactation stages as an estimate of the cow's milk production (CMP). Calving difficulty impaired milk production of dairy cows in terms of CMP and SMY in both herds, highlighting impaired income for dairy producers as well as detrimental effects to the productivity of the cows and potentially impaired health and survival. The management of the herd affected the presence of an effect of each degree of difficulty on SMY and CMP as well as its magnitude and duration. The analysis of SMY, independently of each animal having achieved a full lactation, could be a more sensitive indicator of the subsequent long-lasting biological stresses than CMP alone.

Reducing errors in health care: cost-effectiveness of multidisciplinary team training in obstetric emergencies (TOSTI study); a randomised controlled trial.

BACKGROUND: There are many avoidable deaths in hospitals because the care team is not well attuned. Training in emergency situations is generally followed on an individual basis. In practice, however, hospital patients are treated by a team composed of various disciplines. To prevent communication errors, it is important to focus the training on the team as a whole, rather than on the individual. Team training appears to be important in contributing toward preventing these errors. Obstetrics lends itself to multidisciplinary team training. It is a field in which nurses, midwives, obstetricians and paediatricians work together and where decisions must be made and actions must be carried out under extreme time pressure.It is attractive to belief that multidisciplinary team training will reduce the number of errors in obstetrics. The other side of the medal is that many hospitals are buying expensive patient simulators without proper evaluation of the training method. In the Netherlands many hospitals have 1,000 or less annual deliveries. In our small country it might therefore be more cost-effective to train obstetric teams in medical simulation centres with well trained personnel, high fidelity patient simulators, and well defined training programmes. METHODS/DESIGN: The aim of the present study is to evaluate the cost-effectiveness of multidisciplinary team training in a medical simulation centre in the Netherlands to reduce the number of medical errors in obstetric emergency situations. We plan a multicentre randomised study with the centre as unit of analysis. Obstetric departments will be randomly assigned to receive multidisciplinary team training in a medical simulation centre or to a control arm without any team training.The composite measure of poor perinatal and maternal outcome in the non training group was thought to be 15%, on the basis of data obtained from the National Dutch Perinatal Registry and the guidelines of the Dutch Society of Obstetrics and Gynaecology (NVOG). We anticipated that multidisciplinary team training would reduce this risk to 5%. A sample size of 24 centres with a cluster size of each at least 200 deliveries, each 12 centres per group, was needed for 80% power and a 5% type 1 error probability (two-sided). We assumed an Intraclass Correlation Coefficient (ICC) value of maximum 0.08.The analysis will be performed according to the intention-to-treat principle and stratified for teaching or non-teaching hospitals.Primary outcome is the number of obstetric complications throughout the first year period after the intervention. If multidisciplinary team training appears to be effective a cost-effective analysis will be performed. DISCUSSION: If multidisciplinary team training appears to be cost-effective, this training should be implemented in extra training for gynaecologists. TRIAL REGISTRATION: The protocol is registered in the clinical trial register number NTR1859.

[Obstetric urogenital fistula (OUGF): cost analysis at the Niamey National Hospital (Niger)]. / Fistule urogénitale d'origine obstétricale (Fugo) : coût de la prise en charge à l'hôpital national de Niamey (Niger).

BACKGROUND: A program to eliminate obstetric urogenital fistula (OUGF) was set up on February 19, 2004 in Niger. Though the consultations were free of charge, there was a cost involved, which constitutes the objective of this study. METHOD: The data were obtained from a documentary study completed by discussions with the principal management participants and interviews targeting the women suffering from OUGF attending the national hospital of Niamey during the surgery sessions of April and November 2006. Cost assessment included all resources devoted to activities involved in the program: hospital stay, hygiene education, medical and surgical treatment, social rehabilitation interventions (preparation for revenue generating activities and return to residence). Data analysis was performed with Excel and Epi2000 software. Average cost per item and patient was determined. RESULTS: The cost of the stay at the National hospital of Niamey was 96,445 francs CFA divided between transportation (4,688), room and board (21,572), assistance bonus (3,708) and indirect costs (66,477). The hygiene education cost 194,140 francs CFA: 30,150 for human resources, 143,965 for material resources and 20,025 for operational costs. The medical and surgery treatment had a cost of 144,009 francs CFA divided between consultations (15,000), complementary explorations (44,900), surgical operation (50,000) and consumables (34,109). The preparation for revenue generating activities had a cost of 118,244 francs CFA including training for clothes dying (22,084), soap manufacture (46,160) and the financial supportive grant (50,000). The return to the community cost 295,000 francs CFA, included room and board (2,500), human resources (65,000) and material resources (227,500). Altogether, the cost of the OUGF program came up to 742,018 francs CFA for our sample (76% of women with revenue generating activity), and was assessed at a maximum of 781,362 francs CFA if none of the woman had a revenue generating activity, and a minimum of 729,594 francs CFA if all of them did. CONCLUSION: Without the free consultations, the high cost of the OUGF program at the national hospital of Niamey would be inaccessible to Nigerian women owing to poverty and ignorance. Because of this observation, a long-term program is warranted for the treatment of overt cases and the reduction of prevalence, to enable Nigerian women to contribute to the development activities of their country.

Simple fistulas: diagnosis and management in low-resource settings--a descriptive report.

Obstetric fistulas occur in developing countries because of the scarcity or complete absence of obstetric services. The magnitude of the problem is unknown but thought to be sizeable. This article describes a basic approach to the care of women with fistulas in a low-resource rural hospital in northern Ghana, where the results were similar to those obtained at better-equipped centers. The facility includes an outpatient clinic for history taking and clinical examinations, and a laboratory for hemoglobin concentration assessment, sickling test, blood grouping, and cross-matching when necessary. Anesthesia consists of a spinal anesthesia given by the surgeon and monitored by a nurse while the surgeon scrubs up before repairing the fistula. Surgery is performed with the patient in exaggerated lithotomy position, and a bed sheet used as a sling prevents her from falling backwards. The patients are kept at the hospital for 14 days postoperatively for continuous bladder drainage.
