El Embriotomo de Torpin

Revista Colombiana de Obstetricia y Ginecología, 1954
La embriotomía es una operación destinada a reducir el volumen del feto destruyendo su integridad. Cuando se realiza seccionando íntegramente la co­lumna vertebral y las partes blandas que la rodean, es decir, dividiendo el feto en dos porciones, toma el

The 9+ month marathon: How pregnancy may have shaped human endurance capacities

The Anatomical Record, EarlyView.
Abstract Anthropology has long considered the evolution of our uniquely human endurance capacities to be the result of selection upon anatomical and physiological features imposed by the demands of thermoregulation and resource acquisition, particularly during the demands of persistence hunting. Research has focused on the anatomical changes present in

Historical birth records from 1896 to 1944 from the Basel maternity hospital, Switzerland, reveal significant obstetric selection pressures

The Anatomical Record, EarlyView.
Abstract Maternal and neonatal morbidity and mortality have declined dramatically during the last century. Historical data are therefore important sources to study the evolutionary selection pressures related to childbirth and how they have fluctuated over time.

British National Formulary Guidance on prescribing in pregnancy: A descriptive cross‐sectional study

British Journal of Clinical Pharmacology, EarlyView.
Aim To assess how well pregnancy‐specific guidance within the British National Formulary supports healthcare professionals to facilitate safe and effective medication use. Methods We performed a manifest content analysis of the text of all pregnancy sections within British National Formulary drug monographs, with inductive and iterative coding.

Humans are not unique: difficult birth is common in placental mammals

Biological Reviews, EarlyView.
ABSTRACT Human childbirth is widely presumed to be uniquely difficult and dangerous compared to birth in other mammals. Tight fetopelvic proportions can result in obstructed labour and contribute to high rates of maternal and neonatal mortality. Ideas summarised under the ‘obstetrical dilemma’ have contributed to this assumption by explaining difficult

Neuroimaging Findings and Risk Factors for Brain Injury in Foetuses Treated for Anaemia

Prenatal Diagnosis, EarlyView.
ABSTRACT Objective Characterize neuroimaging findings in foetuses with anaemia and identify associated risk factors. Methods Retrospective cohort study of pregnancies with foetal anaemia (defined as haemoglobin > 2 standard deviations below the gestational age mean) confirmed by foetal blood sampling (FBS) and treated with intrauterine transfusion (IUT)

Double Slag Operating Standard for Mitigation of CO2 Emissions in Basic Oxygen Steelmaking

steel research international, EarlyView.
Basic oxygen furnace (BOF) steelmaking uses a double slag process (DSP) to produce low‐phosphorus steel. To reduce carbon emissions in a BOF, the hot metal ratio (HMR) must be lowered. The present article describes the optimal conditions for DSP operations under low‐HMR conditions: temperature of 1360 ± 5 °C, total Fe content of 10 ± 2 wt%, basicity (=

Experimental and Computational Investigation of Slag–Refractory Interactions Under Conditions Relevant to Hydrogen Plasma Smelting Reduction

steel research international, EarlyView.
This study investigates how slag interacts with magnesia–carbon (MgO–C) refractories under conditions relevant to hydrogen plasma smelting reduction. High‐temperature refractory wear tests are combined with thermodynamic modeling to examine refractory dissolution into slag and slag infiltration into the refractory.

Feasibility, safety, and outcome of fetoscopic endoluminal tracheal occlusion for severe congenital diaphragmatic hernia at a low case-load center: one center's experience

Annals of Saudi Medicine
BACKGROUND: Antenatal fetoscopic endoluminal tracheal occlusion (FETO) has been introduced as an effective intervention to improve the outcome of severe congenital diaphragmatic hernia (CDH). OBJECTIVE: We report our early experience with FETO. DESIGN: A
