Comparación de los efectos de las estatinas sobre las concentraciones séricas de leptina y adiponectina
Authors: Cárdenas-Parra Leidy Yurany , Henry Osorio José
Published: November 2022

Los estudios que relacionan el efecto de las estatinas sobre los niveles de adipocitoquinas, han reportado controversias; por lo que, es necesario contribuir a dilucidar la relación entre estas. El objetivo fue comparar las concentraciones séricas de leptina y adiponectina, en pacientes crónicos, según el régimen de estatina instaurado. El presente estudio es de tipo observacional, transversal, de nivel relacional. Fueron tomados datos de historias clínicas de 76 participantes y se les cuantificó leptina y adiponectina en suero, mediante la técnica de ELISA tipo sándwich. El análisis relacional se realizó mediante las pruebas de U-Mann-Whitney y H-Kruskal-Wallis. Las concentraciones séricas de leptina fueron homogéneas e independientes del régimen de estatina suministrado; por el contrario, las de adiponectina, fueron menores en quienes consumían 40 mg/ día de atorvastatina. Atorvastatina a 40 mg/día se relaciona con concentraciones plasmáticas de adiponectina inferiores, respecto a la adiponectinemia de los participantes manejados con otros regímenes de estatina. Para la comunidad científica es importante investigar sobre estos biomarcadores, para dilucidar relaciones que permitan predecir con mayor precisión el impacto, especialmente de atorvastatina a dosis intermedia y alta, como fármaco con mayores beneficios frente a eventos cardiovasculares y síndrome metabólico.

Published: November 2022

For N-terminally fluoresceine labelled KLALKLALKALKAALKLA-NH2 (I) extensive incorporation into aortic endothelial cells (AEC) was found, resulting in
an about 500-fold enrichment within the cell interior. The cellular uptake was not influenced by energy depletion and only partly by lowering the temperature
to 0oC. Using double-D-amino acid analogs of this peptide, possessing a graduate propensity to adopt anα-helical structure, clear dependency of the peptide
incorporation upon amphipathicity could be demonstrated.

Published: November 2022

Deposition of β-amyloid fibrils within senile plaques in the brain is a major hallmark of Alzheimer's disease. In this study, atomic force microscopy (AFM) has been used to provide surface topographical data of ­ amyloid fibrillization as a function of pH. Alteration of pH has led to observed changes in fibril self-assembly rate, diameter and branching. These results suggest that pH has a profound affect on β-amyloid self-assembly and surface morphology.

Authors: Bahammam Hammam Ahmed
Published: November 2022

Background:

The escalated technological development and the emergence of computer-aided manufacturing have improved dental restoration accuracy and the accurate manufacturing of prosthetic models.

Objective:

The study aims to assess patients' comfort level, preferences, and acceptance of treatment time for conventional impression technique vs. digital impression among orthodontic patients treated with clear aligners.

Methods:

A cross-sectional survey study was conducted between February 2019 and April 2019 by recruiting 50 patients from the orthodontic clinics at multiple centers. A self-administered questionnaire was designed to evaluate patients' perceptions in each impression technique group. Descriptive statistics and paired sample t-test were applied with statistical significance set at P<0.05.

Results:

The results showed that the impression technique bothered patients as they experienced helplessness during treatment. There was a significant impact on patients' perception of the treatment, whereas there was an insignificant association between comfort level and treatment of the patients.

Conclusion:

The technicalities of conventional impression were not applied to the intraoral scanners, making these scanners superior and more user-friendly. Digital impression techniques were also preferred by the participants regarding their time, taste/smell, and sensitivity.

Pulse starch as a promising gelling agent and resistant starch source for industrial applications
Authors:   University of Saskatchewan, Ai Yongfeng
Published: November 2022

As sustainable and protein-rich crops, pulses—including pea, lentil, faba bean, and dry bean—have attracted tremendous interests for the production of plant-based proteins. Nevertheless, starch is the main constituent of pulse grains, the content of which typically ranges from 35% to 52%. Therefore, the global pulse processing industry is developing effective strategies to find new markets for this co-product from pulse protein fractionation. Our recent research demonstrated that: (1) under normal processing conditions (e.g., at 95 °C cooking), round pea and lentil starches formed remarkably stronger gels than commercial starches from other botanical sources; (2) under high-temperature processing conditions (e.g., at 140 °C cooking), wrinkled pea starch developed the firmest gel among common native starches. The gelation mechanisms of various pulse starches over cooking temperatures of 95–140 °C will be illustrated in the presentation. Having relatively higher amylose contents (35–80%) than common commercial starches, pulse starches can be more suitable for the development of resistant starch (RS), a new type of dietary fiber that can deliver low glycemic and insulinemic benefits to consumers. Heat-moisture treatment (HMT) effectively increased the RS contents of round pea (CDC Bronco variety) and wrinkled pea (MPG87 variety) starches from 5.8% to 11.0% and from 21.4% to 29.9%, respectively. The “structure-function-digestibility” relationships of the HMT-modified pea starches will be discussed. The presented unique functional and nutritional attributes of pulse starches will be meaningful for the agri-food industry to generate new value from this leading carbohydrate component in pulse seeds.
Clearing the current confusion in the meaning of the surfactant term in the HLD equation
Authors:   FIRP Laboratory, Universidad de Los Andes, Venezuela, Salager Jean-Louis
Published: November 2022

With the petroleum price crisis in the 1975, new methods to recover crude oil beyond the waterflood typical 25% limit were proposed, in particular the ones using surfactant to produce an extremely low interfacial tension down to 0.001 mN/m or less. Linear relations to attain such exceptional physicochemical occurrence were proposed in 1979-1980 with many variables depending on the components (aqueous brine salinity, oil structure, surfactant head and tail type, temperature and pressure) as well as the composition in water, oil and surfactant. The manipulation of the multivariable equation(s) called  HLD (Hydrophilic-Lipophilic deviation from optimum) has been used in practice not only in petroleum EOR but also in many other applications involving the properties of single or multiple phase macro, mini, micro and nano-emulsions, and it is now clear after 40 years of discussion and interpretation that some names and meanings are confused and must be cleared.
Microbial lipids for nutrition: History, status and future challenges and opportunities
Authors:   DSM, Zirkle Ross
Published: November 2022

The study of and interest in microbial lipids go back for at least 140 years.  Historically, the production of these microbial oils was expensive and complex as compared to the inexpensive, consistent, and robust production of plant oils.  Additionally, the attributes of these microbial oils were often similar to commoditized plant oils.  In the 1960s and 1970s, more focus shifted to the discovery of unique attributes of microbial oils and the development of these systems led to some minor commercialization of nutritional microbial lipids in the 1970s and 1980s.  Starting in the 1990s, and continuing today,  significant success in the development and commercialization of nutritional microbial oils containing Omega-3 and Omega-6 long-chained polyunsaturated fatty (PUFA) acids has been seen.  Progress continues to be made in the technology of microbial lipid production in both genetically modified and non-genetically modified systems. While the interest level in microbial lipids and systems continues to run high, there has only been relatively narrow success in commercialization of PUFA microbial oils to date. The presentation will review the history, status, and future challenges and opportunities for microbial lipids for nutrition.
Cc variances as a result of sophorolipid lactone/lactonic acid ratios

Published: November 2022

It has been established that the so-called characteristic curvature (Cc) of a surfactant is helpful to formulators of various industries in optimizing systems for wetting, emulsifying, and so forth.  Determination of surfactant Cc has been well explored and methods of determination of that characteristic value abound.  Sophorolipids present a specific problem, however, as these biosurfactants may take one of two structures and usually a combination of both.  The first structure is the ring-like lactone structure, which is nonionic.  The second structure, the more linear lactonic acid, is formed when the first structure undergoes hydrolysis and becomes a bolaform surfactant.  One side of the bolaform is nonionic, but the other side, terminating with a carboxylic acid function, is anionic above pH 5.  Two difficulties in determining the Cc are presented as a result of this transformation.  The first is that of combining terms for a nonionic surfactant and an anionic surfactant at various ratios which are often pH dependant.  The second problem is that the lactonic acid has been shown exhibit unusual self-assembly properties as a single moiety, let alone as part of a two component system with the lactone.The discussed work examines variances in Cc for a commercial sophorolipid under pH induced ratios and aggregation.
Opportunities and challenges for the development of insect protein-rich ingredients
Authors:   Université Laval, Doyen Alain
Published: November 2022

Over the past decade, the potential of edible insects as a novel food ingredient in high value-added products has been investigated to find alternatives to conventional animal protein sources that are over-exploited and harmful to the environment. One of the most challenge for the edile insect industry is to improve the consumer acceptability for this non conventional food matrix. Although there are many complex factors that influence the consumers' perceptions and acceptability of insects as food, it is well-documented that insect-based foods in which insects were not visible to the consumer created less aversion, highlighting the importance of developing products with processed insects. In this context, the development of edible insect ingredients, from meal until insect protein isolate, is currently largely studied. More specifically, and because these ingredients are composed of a high amount of proteins, this macronutrient is of specific significance. In this context, edible insect proteins represent a great opportunity for the development of the edible insect industry due to their interesting nutritional aspect and bioactive properties. However, for the development of edible insect-based food for human consumption, it become necessary to control the impact of conventional and emerging food processing on the insect protein structures and techno-functional properties. Simultaneously, it is crucial to ensure that the insect-based food products generated after the different processing steps are safe for the consumer, mainly in terms of microbial contaminations and allergenicity. Consequently, and regarding the different points indicated above, this presentation will highlight the different opportunities and challenges regarding the development of insect protein-rich food ingredients.
Microalgae based triglyceride alternatives to vegetable and animal derived oils/fats for food and nutrition applications
Authors:   Checkerspot Inc., Rakitsky Walter
Published: November 2022

Triglycerides produced by microalgae can be optimized for replacement of targeted vegetable oils/animal fats via mutagenesis or genetic engineering. The natural tendency of microalgae to orient unsaturated fatty acids at the Sn2 position makes it an ideal organism to use for vegetable oil/fat alternatives but problematic for animal fats such as pork. Recent progress in the area of regiospecificity control indicates that fats/oils with significant selective enhancement of saturated fatty acid content at the Sn2 position is feasible in microalgae and can be further developed into viable alternatives to animal fats for inclusion in plant-based food formulations.
The zipper self-assembly effect applied to naphthenic acid systems
Authors:   University of Toronto, Acosta Edgar , Perez Rafael ,   University of Toronto
Published: November 2022

Naphthenic acids (NAs) are naturally-occuring cylic and aromatic fatty acids found in a variety of crude oils. Naphthenic acids and their neutralized form, sodium naphthenates (NaN), have been identified as the main surface-active species present in bitumenous oils, controlling most of their interfacial behavior. Different from other fatty acids, that upon neutralization undergo phase inversion and experience ultralow IFT, naphthenic acids do not produce such ultralow interfacial tension. This presentation introduces a discussion about the possible reasons that explain this unusual behavior. Some of those reasons include the possibility of extremely hydrophilic and hydrophobic components in the NA + NaN mixture, similar to the behavior of hydrophilic and lipophilic linkers used in microemulsion formulations. It has been previously shown that mixtures of hydrophilic and lipophilic linkers do not produce microemulsions (and thus ultralow interfacial tensions), but that with addition of a small amount of a surfactant of intermediate hydrophobicity, they can self-assemble to produce large bicontinuous microemulsions. This idea is explored in this work to produce low to ultralow interfacial tensions with partially neutralized naphthenic acids in the presence of a model oil. The potential implications and applications of these findings are discussed.

Published: November 2022

Lentil (Lens culinaris Medik) is an important source of plant-based protein, and the protein and amino acid contents have a significant influence on its nutritional value and use. This study developed near-infrared reflectance spectroscopy (NIRS) calibration models to predict the protein and 18 amino acid contents of lentil seeds. The effects of sample status (whole and ground), type of spectrometer (DA 7250 and FT 9700), and amino acid/protein correlation on model performance were analyzed and evaluated. In total, 361 lentil samples grown in Saskatchewan, Canada, were selected as a calibration set. These samples were scanned by spectrometers and analyzed by reference wet chemistry methods to obtain spectral data and reference data, respectively. NIRS models developed by partial least squares (PLS) equation had a satisfactory performance for measuring protein and most amino acids (except for histidine, tyrosine, methionine, and cysteine) in lentils with high coefficients of determination for calibration (R2C = 0.652–0.927) and residual predictive deviation (RPD = 1.570 – 3.101). NIRS models from DA 7250 achieved similar accuracy for the determination of crude protein and amino acids in whole and ground lentils. DA 7250 models had a slightly better predictive ability with higher coefficients of determination for cross-validation (R2CV) and RPD values than FT 9700 models for all compositions except histidine. However, the predicted data of the two spectrometers did not differ significantly (p > 0.05) for every composition. For amino acids highly correlated to crude protein, NIRS generally predicted them with higher accuracy. Overall, NIRS combined with PLS regression yielded significant potential for rapid and simultaneous prediction of protein and most amino acid contents in lentils with satisfactory accuracy, and these models were usable for research purposes or sample screening.

Water-in-oil emulsions are commonly unavoidable and undesirable in the production, transportation, and refining of petroleum and related products. The emulsions are stabilized by a variety of surface-active compounds found in crude oil such as natural surfactants and fine mineral particles. A critical step in the processing of crude oil is to break the interfacial film formed at the oil/water interface to enable the coalescence and separation of water from oil. Demulsifiers are commonly used to promote the water removal process. However, the effectiveness of a demulsifier varies greatly due to the oil sources, water content, and processing. This presentation will describe our research efforts on breaking water-in-oil emulsions focusing on water-in-oil interfacial properties that govern emulsion stability and demulsification. Fundamental studies were done to understand the effect of selected additives on the interfacial behaviors using molecular and dissipative particle dynamics simulations, and microfluidics. The modeling and empirical results show that the effectiveness of an additive is correlated inversely to the coalescence time of two water droplets.
How to use in practice a simplified HLDN linear equation for surfactant mixtures

Published: November 2022

In 1948 Winsor proposed the R ratio of the interactions at interface of the adsorbed surfactant molecules with oil (Aco) and water (Acw). At the R=Aco/Acw=1 condition, a three-phase behavior was attained. This occurrence in a continuous scan of a formulation variable, susceptible to change any interaction, was also mentioned to correspond to a low interfacial tension and low emulsion stability, among other properties. In 1975, Enhanced Oil Recovery initial studies indicated the necessity of attaining a very low interfacial tension minimum, i.e., the R=1 physicochemical balance situation presented by Winsor 25 years before. The experimental methods started expressing Winsor's optimum ratio condition (R=Aco/Acw=1) as the equivalent zero difference of interactions between the surfactant and oil and water, i.e., D=Aco-Acw=0. This motivated to numerically express the effects of formulation variables occurring in a petroleum reservoir to attain a minimum low IFT. The hydrophilic-lipophilic deviation (HLD=D/RT) from optimum formulation was expressed as a linear normalized equation as follows:HLDN = - ACN + Ks ln S €“ Kt T + C for ionic surfactants like sulfonates or carboxylatesHLDN = - ACN + K's S + K't  T + C' for nonionic ethoxylated surfactants. Where S is the aqueous salinity, ACN is the oil nature (alkane carbon number), T is the temperature. The C and C' term includes the remaining variables as the head and tail characterization of the surfactant and eventual co-surfactant, the pressure, and the SOW composition. The C and C' also consist of the proportion X of the different species if there are two or more surfactants when a mixture is used. Herein, it is shown that there are different ways to express the effect of the mixture in the previous equations, that is, as a linear relation Kc X term over some range of mixture composition.
Spent hen proteins: An untapped bioresource for food packaging applications
Authors:   University of Alberta, Zubair Muhammad , Ullah Aman ,   University of Alberta, Wu Jianping ,   University of Alberta
Published: November 2022

Spent hens, a poultry by-product, have little economic value for processing due to poor meat quality and low yield. In North America alone, 150 million spent hens are produced every year which are either end up in landfill or burnt. However, there are concerns over disposal of spent hens; therefore, it is pertinent to find out alternative uses that are environmentally friendly. On the other hand, single-use plastic packaging is leading to a global environmental crisis. The development of hybrid bionanocomposite films from spent hen proteins using cellulose nanocrystals (CNCs) is a viable option for food packaging applications. In this study, proteins were harvested from spent hen using alkali aided extraction method. To develop protein derived bionanocomposite films, glycerol was used as a plasticizer and chitosan as a cross-linker agent. Furthermore, cellulose nanocrystals (1,3,5%) were incorporated into the proteins/glycerol/chitosan mixture and sonicated it for an hour. Finally, mixture was transformed into food packaging films using compression molding and characterized using FTIR, XRD, TEM, DMA, DSC and TGA.The results indicated that alkali aided method provided excellent proteins recovery yield (74%) and percentage purity (96%) from spent hen. The physicochemical analysis showed an improvement in the thermal, mechanical, and barrier properties of the prepared bionanocomposite films. A greater enhancement in mechanical strength (2.65± 0.50 to 8.48±0.98 MPa) of CNCs derived films was observed as compared to films without nanoparticles. Transmission electron microscopy images confirmed the dispersion of CNCs into the protein polymeric chains which resulted in good exfoliation/intercalation of CNCs and improved the overall properties of the films.The above results suggested that spent hen proteins have great future potential to develop protein/CNCs hybrid bionanocomposite films with improved functional properties for food packaging applications. The petro-based plastic environmental impacts can be reduced with the development of these environmentally benign bionanocomposite films.
Structural design of plant protein gel networks for food applications
Authors:   University of Alberta, Chen Lingyun
Published: November 2022

Gelation is one of the most important functional properties of proteins as it provides texture and structure in foods. Gelatin, egg white and whey proteins are widely used as gelling agents in the food industry. Plant proteins are considered inferior to animal proteins in gelling properties. With the recent surge in demand led by sustainability and health considerations, plant-based food products have taken a center stage in food product innovation. This trend has spurred academic and industrial interest to explore the opportunity of developing gelling ingredients from diversified plant protein sources, replacing animal protein based gels. This presentation will introduce the recent research efforts in our group to develop gelling properties from emerging sources of plant proteins (e.g. pea, lentil and oat). The structural design approaches (e.g. pH-shifting, protein aggregates to build gel network) and novel technologies (e.g. cold plasma, high pressure) that have potential to increase gel performances from plant proteins will be highlighted. The gel rheological properties and mechanical strength as impacted by the protein composition, conformation and aggregation will be discussed. The food application of plant protein based gels will be illustrated.
Functional, nutritional properties and aroma profile of hemp protein isolate by reverse micelles extraction technique: impact of defatting processing
Authors:   North Dakota State University, Fang Baochen , Rao Jiajia ,   North Dakota State University
Published: November 2022

There is an increased awareness of the incorporation of hemp protein in a commercial product on account of its high nutritional value and neutral flavor. One of the factors that impact the functional properties of hemp protein is the isolation conditions. In recent years, reverse micelles (RMs) has emerged as a powerful technique for extracting protein and enzyme because of low cost, convenience, and potential for scaling up in the manufacturing process. For oil crops, it generally requires long defatting processing before protein extraction. Therefore, it would be interesting to investigate whether the defatting of hempseed flour would impact on physicochemical properties of hemp protein using the RM extraction method. Our results revealed that high protein recovery yield (69.37-70.21%) and protein purity (92.76-95.2%) of hemp protein isolate (HPI) could be obtained through the RM technique using either non-defatted hemp flour (ND-HF) or defatted hemp flour (D-HF). Concerning the defatting processing, both HPIs showed great similarity in protein composition, and functional properties including solubility, thermal stability, foaming, and emulsifying properties. Interestingly, HPI obtained from ND-HF had higher essential amino acid ratio when compared to D-HF. Beyond that, distinct gelling behaviors (least gelling concentration, gel strength, and color) have been observed. The HPI gel obtained from ND-HF displayed a higher least gelling concentration (4%) with yellowish color than that of HPI gel from D-HF (2%). In terms of aroma profile, a significantly high number of aromatic compounds with a greater abundancy were detected in HPI from ND-HF (33) as compared to HPI isolated from D-HF (26), which contributed to the different process conditions and lipid content. The research findings provided an eco-friendly protein isolation method with premium functional attributes, especially for oil crops, which pave the way for the future application of RMs in a wide range of protein extraction.
Protein gelation enhances resistance to proteolysis and in vivo cholesterol-lowering ability of the indigestible proteins
Authors:   University of Manitoba, Aluko Rotimi
Published: November 2022

Cardiovascular diseases are leading causes of death globally with excessive levels of blood cholesterol being a major risk factor. A dietary approach towards reducing this health risk is the intake of foods enriched with indigestible proteins that bind cholesterol to minimize reabsorption from the gastrointestinal tract. However, the level of indigestible proteins in regular foods is low and normal dietary intake may not provide sufficient cholesterol-lowering effect. Therefore, the aim of this work was to utilize various processing techniques to enhance resistance of food proteins to proteolysis and facilitate recovery of large amounts of indigestible proteins, which was then incorporated into the diet of Sprague-Dawley rats. Various legume seed protein isolates were subjected to the following pretreatments: dry heat, wet heat, autoclave, gelation, and freeze-thaw (3 cycles). The pretreated isolates were digested with pepsin followed by pancreatin to obtain insoluble residue as the indigestible product, which was tested for in vitro bile acid-binding ability. Results showed that the indigestible proteins from gelled cowpea protein isolate (ICP) was most abundant (68% yield) and had strong bile acid-binding ability. The rats were fed high fat diets and divided into 4 groups of 6 each (3 males + 3 females): group 1 was 20% casein diet while groups 2, 3 and 4 consumed same diets but casein was partially substituted with 1% ICP, 5% ICP, and 5% undigested cowpea protein isolate (CPI), respectively. After feeding for 6 weeks, rats that consumed the diet containing 5% ICP had the lowest increase in plasma total cholesterol of 1.8 mmol/L when compared to increases of 9.34 and 4.15 mmol/L for CPI and casein only diets, respectively. Analysis of the fecal matter by gel electrophoresis confirmed the presence of a high molecular proteins in the ICP-containing diets but absent in the casein only and CPI diets.
pavimentos Nolla de Meliana, una joya del mosaico cerámico. Estudio y catalogación para su conservación preventiva

Published: November 2022

La Fábrica de Mosaicos Nolla fue construida por Miguel Nolla Bruget hacia 1860 en las afueras de Meliana (Valencia, España). Su creación significó un gran cambio a nivel social, económico e industrial de la región.

Fue una empresa que consiguió situarse entre los máximos referentes europeos y exportó su producto tanto a nivel nacional como internacional, siendo ganadora de numerosos premios y medallas gracias a la calidad de los mosaicos cerámicos producidos, las buenas condiciones de trabajo de los operarios y las innovaciones tecnológicas que se implantaron en el sistema de producción.

La importancia y el impacto de la fábrica fueron rápidamente olvidadas desde el momento del cierre de la empresa en la década de los 70 del pasado siglo. Esto provocó el abandono del Palauet de Nolla, la destrucción de parte de las instalaciones originales de la fábrica, y la pérdida de una gran cantidad de mosaicos irrepetibles hoy en día.

Actualmente se está trabajando en la recuperación de este patrimonio y en su puesta en valor. Este proyecto contribuye a este objetivo mediante el estudio del caso concreto de los mosaicos Nolla que todavía se conservan in situ en Meliana y la creación de una ficha base para su catalogación.

Using Magnetic Resonance Imaging During Childbirth to Demonstrate Fetal Head Moldability and Brain Compression: Prospective Cohort Study
Authors: Ami Olivier , Maran Jean-Christophe , Musset Dominique , Dubray Claude , Mage Gérard , Boyer Louis
Published: November 2022

Background

Childbirth is a physiological process with significant medical risk, given that neurological impairment due to the birthing process can occur at any time. Improvements in risk assessment and anticipatory interventions are constantly needed; however, the birthing process is difficult to assess using simple imaging technology because the maternal bony pelvis and fetal skeleton interfere with visualizing the soft tissues. Magnetic resonance imaging (MRI) is a noninvasive technique with no ionizing radiation that can monitor the biomechanics of the birthing process. However, the effective use of this modality requires teamwork and the implementation of the appropriate safeguards to achieve appropriate safety levels.

Objective

This study describes a clinically effective and safe method to perform real-time MRI during the birthing process. We reported the experience of our team as part of the IMAGINAITRE study protocol (France), which aimed to better understand the biomechanics of childbirth.

Methods

A total of 27 pregnant women were examined with 3D MRI sequences before going into labor using a 1-Tesla open-field MRI. Of these 27 patients, 7 (26%) subsequently had another set of 3D MRI sequences during the second stage of labor. Volumes of 2D images were transformed into finite element 3D reconstructions. Polygonal meshes for each part of the fetal body were used to study fetal head moldability and brain compression.

Results

All 7 observed babies showed a sugarloaf skull deformity and brain compression at the middle strait. The fetus showing the greatest degree of molding and brain shape deformation weighed 4525 g and was born spontaneously but also presented with a low Apgar score. In this case, observable brain shape deformation demonstrated that brain compression had occurred, and it was not necessarily well tolerated by the fetus. Depending on fetal head moldability, these observations suggest that cephalopelvic disproportion can result in either obstructed labor or major fetal head molding with brain compression.

Conclusions

This study suggests the presence of skull moldability as a confounding factor explaining why MRI, even with the best precision to measure radiological landmarks, fails to accurately predict the modality of childbirth. This introduces the fetal head compliance criterion as a way to better understand cephalopelvic disproportion mechanisms in obstetrics. MRI might be the best imaging technology by which to explore all combined aspects of cephalopelvic disproportion and achieve a better understanding of the underlying mechanisms of fetal head molding and moldability.
Social Media is Addictive and Influences Behavior: Should it Be Regulated as a Digital Therapeutic?

Recently, we were deeply saddened by the findings of the coroner investigating the death of 14-year-old Molly Russell. Deeply saddened and angry but not surprised. This case should be seen as a sentinel event, given that this is the first time social media was directly implicated as a cause of death. We should use this opportunity to advance proposals for the regulations of the health effects of social media.
