What motivates Muslims women to induce lactation?: An exploratory qualitative analysis
Authors: Che Abdul Rahim Norsyamlina , Sulaiman Zaharah , Tengku Ismail Tengku Alina
Published: November 2023

Induction of lactation occurs when breast milk is produced in a human (female), without going through the process of pregnancy and delivery. Induced lactation is a method of strengthening the bond between the adopted child and the adoptive mother.  The primary goal is to encourage bonding solely to develop an emotional connection and as a motivation for the mother to breastfeed her adopted child. This exploratory qualitative study examined the factors influencing women's decisions about induced lactation in Malaysia. Methods: This study used in-depth interviews with women who had induced lactation in five states based on five regions in Malaysia [Central Region (Selangor), Northern Region (Penang), Southern Region (Johor), East Coast Region (Kelantan), Malaysia Borneo (Sabah)]. The qualitative approach helped to establish a comprehensive insight into the women’s experiences throughout the journey of induced lactation. All interviews were consented, audio-recorded, and transcribed verbatim, followed by identification of emerging themes. Results: After interviewing 23 induced lactation women, data saturation was achieved. Data synthesized using thematic analysis revealed three themes describing the main factors in determining women's decisions on induced lactation: (1) mahram relationship, (2), and (3) the perceived superiority of breastfeeding.  This indicates that the mahram relationship, experiencing motherhood, and the perceived superiority of breastmilk motivated women to undergo induced lactation. Conclusions: Induced lactation is analogous to ordinary life, where favorable attitudes are followed by a strong drive to achieve. We hope that by identifying the various factors that motivate women to induce lactation, health care professionals and the community will be empowered to support breastfeeding in terms of facilitating motherhood, providing breastfeeding aid equipment, and assisting with daily necessities.

Published: November 2023

Background: Indonesia has reported more than 4 million confirmed COVID-19 cases as of November 2021. This has led to an increase in the use of personal protective equipment (PPE), for example, surgical masks in hospitals, especially referral hospitals for COVID-19 patients. The Potential Hydrogen (pH) or level of acidity plays an important role in the body's physiological functions and regulates the formation of an epidermal barrier (stratum corneum). Thus, the use of surgical masks is able to influence the pH of human skin. This study aimed to determine the difference in facial skin acidity (pH) levels of nurses at Sebelas Maret University Hospital before and after surgical mask use.

Methods: The study utilized a cross-sectional observational method and was conducted at the Sebelas Maret University Hospital, Surakarta. A total of 55 subjects were involved in this study, and each subject’s facial skin Potential Hydrogen (pH) was measured before and after surgical mask use. Subsequently, all data were analyzed with a T-test using SPSS 21.00, and a p-value <0.05 indicated statistical significance.

Results: The results showed facial skin pH increased after surgical mask use for nurses at the Sebelas Maret University Hospital (p = 0.000).

Conclusion: An increase in the physiological value of skin pH was observed in the nurses of Sebelas Maret University Hospital after surgical mask use.

Diffuse idiopathic skeletal hyperostosis and axial spondyloarthritis—similarities and differences
Authors: Kiefer David , Khan Muhammad Asim , Baraliakos Xenofon
Published: November 2023

Diffuse idiopathic skeletal hyperostosis (DISH) and axial spondyloarthritis (axSpA) are diseases with inflammatory involvement of the axial skeleton that can result in new bone formation that may lead to total ankylosis of the spine and functional impairment of different extent in individual patients. In these diseases, the new bone formation may lead to total ankylosis of the spine and impaired mobility with functional impairment. This review will highlight the similarities and differences of these two conditions. In axSpA, the genetic background with the association with human leukocyte antigen-B27 (HLA-B27) is known for 50 years, while in DISH, a genetic contribution is not yet proven. The phenotype of new bone formation and its anatomic features are different between these diseases. In axSpA symmetric, thin and marginal syndesmophytes representing an ossification of enthesitic inflammation at the area of the attachment of the annulus fibrosus that may extend to the adjacent deeper layers anterior longitudinal ligament and are typical, while in DISH the so-called “chunky bridging osteophytes” grow as an additional layer on the anterior longitudinal ligament. Besides distinct anamnestic and clinical features, magnetic resonance imaging is helpful differentiating the two diseases since inflammatory changes with the typical pattern of axSpA are reliably visualized. Similar in both diseases is the high prevalence of vertebral fractures, which are mainly caused by the local osteoporosis and decreased flexibility of the affected bones, and therefore may occur even after minor traumata. The presence of extraarticular manifestations like uveitis, inflammatory bowel disease or psoriasis are only linked to axSpA. In contrast, DISH is associated with obesity, diabetes mellitus, and other metabolic diseases. Although DISH and axSpA are distinct conditions, the cooccurrence of these two diseases exists in some patients. Various therapeutic options are becoming available for axSpA, but no therapy has been approved for DISH yet.
Development of a machine learning-based model for predicting risk of early postoperative recurrence of hepatocellular carcinoma
Authors: Zhang Yu-Bo , Yang Gang , Bu Yang , Lei Peng , Zhang Wei , Zhang Dan-Yang
Published: November 2023

BACKGROUND

Surgical resection is the primary treatment for hepatocellular carcinoma (HCC). However, studies indicate that nearly 70% of patients experience HCC recurrence within five years following hepatectomy. The earlier the recurrence, the worse the prognosis. Current studies on postoperative recurrence primarily rely on postoperative pathology and patient clinical data, which are lagging. Hence, developing a new pre-operative prediction model for postoperative recurrence is crucial for guiding individualized treatment of HCC patients and enhancing their prognosis.

AIM

To identify key variables in pre-operative clinical and imaging data using machine learning algorithms to construct multiple risk prediction models for early postoperative recurrence of HCC.

METHODS

The demographic and clinical data of 371 HCC patients were collected for this retrospective study. These data were randomly divided into training and test sets at a ratio of 8:2. The training set was analyzed, and key feature variables with predictive value for early HCC recurrence were selected to construct six different machine learning prediction models. Each model was evaluated, and the best-performing model was selected for interpreting the importance of each variable. Finally, an online calculator based on the model was generated for daily clinical practice.

RESULTS

Following machine learning analysis, eight key feature variables (age, intratumoral arteries, alpha-fetoprotein, pre-operative blood glucose, number of tumors, glucose-to-lymphocyte ratio, liver cirrhosis, and pre-operative platelets) were selected to construct six different prediction models. The XGBoost model outperformed other models, with the area under the receiver operating characteristic curve in the training, validation, and test datasets being 0.993 (95% confidence interval: 0.982-1.000), 0.734 (0.601-0.867), and 0.706 (0.585-0.827), respectively. Calibration curve and decision curve analysis indicated that the XGBoost model also had good predictive performance and clinical application value.

CONCLUSION

The XGBoost model exhibits superior performance and is a reliable tool for predicting early postoperative HCC recurrence. This model may guide surgical strategies and postoperative individualized medicine.
Application of the local Moran index to detect electoral anomalies
Authors: Materukhin Ilya
Published: November 2023

This article discusses the use of one of the methods of spatial analysis, as the local Moran index, for analyzing election results in order to identify the existence of electoral anomalies. The author conducted a study based on the results of the 2016 parliamentary elections in the context of Moscow districts for the five largest parliamentary parties:“Edinaya Rossiya”, KPRF, LDPR, “Spravedlivaya Rossiya” and “Yabloko”. Cartograms of clusters of spatial autocorrelation were obtained for each batch, according to the results of which areas with abnormal results were identified. Electorally abnormal areas were considered for which a violation of the neighborhood effect was recorded, that is, there was a difference in the voting index from neighboring areas. An analysis was also carried out and possible reasons for these differences were expressed. In conclusion, it was noted that some parties demonstrate uniformity in the territorial distribution of votes, which is why abnormal areas were not allocated. Conclusions were also drawn about the effectiveness of using this spatial analysis method to identify electoral anomalies. At the end, the general results of the work were spelled out, including also possible further ways of developing this topic.
Temporal speed prevails on interval duration in the SNARC-like effect for tempo
Authors: Mariconda Alberto , Murgia Mauro , De Tommaso Matteo , Mingolo Serena , Agostini Tiziano , Prpic Valter
Published: November 2023

The Spatial-Numerical Association of Response Codes (SNARC) effect is evidence of an association between number magnitude and response position, with faster left-key responses to small numbers and faster right-key responses to large numbers. Similarly, recent studies revealed a SNARC-like effect for tempo, defined as the speed of an auditory sequence, with faster left-key responses to slow tempo and faster right-key responses to fast tempo. In order to address some methodological issues of previous studies, in the present study we designed an experiment to investigate the occurrence of a SNARC-like effect for tempo, employing a novel procedure in which only two auditory beats in sequence with a very short interstimulus interval were used. In the “temporal speed” condition, participants were required to judge the temporal speed (slow or fast) of the sequence. In the “interval duration” condition, participants were required to judge the duration of the interval between the two beats (short or long). The results revealed a consistent SNARC-like effect in both conditions, with faster left-hand responses to slow tempo and faster right-hand responses to fast tempo. Interestingly, the consistency of the results across the two conditions indicates that the direction of the SNARC-like effect was influenced by temporal speed even when participants were explicitly required to focus on interval duration. Overall, the current study extends previous findings by employing a new paradigm that addresses potential confounding factors and strengthens evidence for the SNARC-like effect for tempo.

Due to the active development of marine transportation infrastructure and possible occurrence of accompanying hydrocarbon pollution, there is a need to develop new safe methods of both direct elimination of pollution and its consequences. One of the promising and safe ways is the use of products based on oil-degrading microorganisms. In this work the influence of Arthrobacter psychrochitiphilus ARC 42 strain on the main links of marine ecosystems is considered. It was found that the studied strain did not inhibit the development of saprophytic microbiota, in high concentrations influenced the development of phytoplankton culture, practically had no effect on benthic organisms. Strain ARC 42 in the recommended concentrations is safe for fish and does not affect their physiological parameters. Experiments with the addition of oil revealed the absence of toxicity of its decomposition products, which confirms the safety of using the preparation based on this strain.

Más allá de la Automatización: Inteligencia Artificial y sus Implicaciones en la Docencia y el Mundo del Trabajo
Authors: Zacarías Torres Antony del Ángel
Published: November 2023

La revolución de la inteligencia artificial (IA) ha permeado múltiples ámbitos de nuestra cotidianidad, con plataformas como Chat GPT en la vanguardia. Dicha evolución, aunque significativa, ha planteado retos éticos en el contexto educativo, especialmente en la integridad de las investigaciones académicas. Mientras que muchos académicos ven en la IA una herramienta valiosa, otros temen que pueda erosionar la esencia misma de la formación y la investigación. Según IBM, la IA se define como la capacidad de las máquinas de replicar habilidades cognitivas humanas, incluyendo el razonamiento y la toma de decisiones. En contraste, la Universidad Nebrija en España distingue dos corrientes de IA: la clásica o simbólica, que utiliza símbolos y es completamente programable; y la conexionista, que se autoconfigura mediante procesos de aprendizaje y se fundamenta en redes neuronales. Aunque la adopción de tecnologías basadas en IA no es nueva, su penetración en el tejido social ha generado un espectro variado de opiniones, reflejando tanto sus oportunidades como sus desafíos inherentes. La proliferación de plataformas basadas en IA ha generado un impacto social notable, facilitando el acceso a información y la generación de contenidos variados. No obstante, también ha suscitado preocupaciones en cuanto a la sustitución de trabajo humano y la posible perpetuación de desigualdades. La ONU promueve una perspectiva de derechos humanos hacia la IA, instando a una regulación basada en principios universales. Por su parte, la UNESCO ve en la IA una herramienta para combatir desigualdades educativas, impulsando un uso inclusivo y equitativo en la educación.

Se comparte con el lector el avance obtenido de la experimentación en el desarrollo de una nueva propuesta de hidroponia tipo NFT basada en integrar el reciclaje de botellas de PET y diseños en impresión 3d. Esto con la finalidad de proponer un nuevo método de cultivo de hortalizas el cual ahorre  aún mas agua que los sistemas conocidos e igualmente  pueda repercutir positivamente en el medio ambiente. Es importante aclarar que la técnica de película de nutrientes (nft) es un sistema hidropónico en el que las plantas se cultivan en canales poco profundos con una película de solución nutritiva que fluye continuamente sobre las raíces de las plantas. (Hernández, 2005) Se propone el uso de la metodología de experimentación pura para establecer una relación causal entre la confiabilidad del sistema hidropónico y los resultados en las hortalizas cosechadas, medidos en términos de peso, tamaño y calidad. Finalmente se abordarán temas técnicos tales como construcción del sistema, formulas nutrimentales para las hortalizas y evidencias que respalden gráficamente el desarrollo de este sistema.
Estilos de Vida y Rendimiento Académico de los Estudiantes de Ciencias e Ingenierías Físicas y Formales de una Universidad Privada Peruana
Authors: Pari Rodríguez Nelly Jaqaru
Published: November 2023

Las instituciones de educación superior tienen la crucial tarea de ofrecer una formación integral a sus alumnos, siendo esencial que sus planes de estudio enfaticen la promoción de un estilo de vida saludable. Esto influye directamente en la calidad del aprendizaje de los estudiantes y, por ende, en su desempeño académico durante su formación. No obstante, en la Universidad Católica de Santa María, se ha notado que el rendimiento académico de los estudiantes, especialmente en la Facultad de Ciencias Físicas y Formales, así como en Ingeniería, no alcanza las expectativas en la mayoría de los casos. Un alto porcentaje de estudiantes no logra obtener calificaciones que reflejen un sólido proceso de aprendizaje, y esto podría deberse a varios factores que dificultan su mejora. El problema central que aborda esta investigación se centra en la relación entre los estilos de vida de los estudiantes que cursaron el segundo semestre en la Facultad de Ciencias Físicas y Formales, así como Ingeniería, en la Universidad Católica de Santa María en Arequipa y su rendimiento académico. El propósito principal es determinar la asociación entre estos dos aspectos. La metodología empleada consistió en un estudio correlacional de corte transversal, con una muestra de 320 estudiantes de dicha facultad. Los resultados revelan una correlación moderadamente positiva entre los estilos de vida de los estudiantes y su rendimiento académico en las cinco carreras estudiadas, respaldada por un valor de p igual a 0.426 en la prueba estadística de r de Pearson, con un nivel de confianza del 95%.

Entre las varias técnicas constructivas empleadas por los artesanos de la época virreinal, la fabricación de cielorrasos en la cara interior de las coberturas de las edificaciones limeñas es una que ha pasado bastante desapercibida entre los historiadores de la arquitectura. Aunque de manera muy limitada, podemos trazar el uso de cielorrasos en algunos edificios desde el siglo XVII, fabricados con una variedad de materiales dependiendo de la época. Este artículo tiene como objeto documentar el uso de cielorrasos en Lima, describiendo los materiales utilizados, la técnica desarrollada para su fabricación y la decoración que pudieron haber ostentado, e identificando los ejemplares -existentes o desaparecidos- que se ejecutaron en la época virreinal. Esto con la finalidad de enriquecer el conocimiento de las técnicas constructivas empleadas durante dicho período, así como de echar luz sobre esta técnica en particular y su impacto en el desarrollo de la arquitectura limeña.
Les dynamiques de fusion face aux défis de la spécialisation : cas de la formation des enseignants du 21ème siècle au Maroc
Authors: Bouabdallah Ibrahim
Published: November 2023

La fusion comme un outil de modernisation des organisations est confrontée aux contraintes de la spécialisation qui peut limiter sa garantie de réussite. Une méta-analyse de quarante-six documents a permis d’identifier, depuis la dernière décennie, quatre principales fusions ayant guidé les réformes de la formation des enseignants visant améliorer la qualité des acquisitions des élèves. D’abord, les Centres régionaux des métiers de l’éducation et de la formation ont élargi les parcours de formation justifiant une convergence vers la généralisation qui ignore les détails. Ensuite, les deux concours de recrutement des enseignants des cycles secondaires ont été substitués par un seul concours suggérant une similitude entre les profils d’entrée des candidats. Par ailleurs, la fusion des dispositifs de formation pour les cycles secondaires a réduit de moitié le nombre des cursus de formation. Enfin, la fusion statutaire a permis de satisfaire les besoins des établissements scolaires, et a orienté les fonctions des enseignants vers le processus d’enseignement.

Ground level enhancements (GLEs) of cosmic radiation are the result of solar energetic particles (SEPs) arriving at the Earth, potentially causing major damage to technological systems, but also posing a threat for
human health. Intense SEPs, such as the GLE events, can influence the radiation exposure of aircrafts and consequently increase the radiation dose on human crew, but also have an impact on satellites and affect the
design of space missions, i.e electronic devices onboard the satellite platforms etc. Therefore, predicting such events is challenging and one of the most important aspects of space weather research. In this work the
updated GLE Alert++ System of the Athens Neutron Monitor Station (A.Ne.Mo.S.) implemented by the Athens Cosmic Ray Group of the National and Kapodistrian University of Athens (NKUA) is being presented. Moreover, the
innovations of the updated system in relation to the previous version of the GLE Alert Plus are introduced. Finally, the most recent and the first of solar cycle 25 GLE event, GLE73, is discussed. This event was
registered by several stations of the worldwide ground-based neutron monitor network. An accurate alert was issued successfully by the ESA R-ESC federated product GLE Alert Plus, as well as by the updated GLE Alert++
System of the NKUA/A.Ne.Mo.S. It should be emphasized that GLE Alert++ signal by NKUA/A.Ne.Mo.S. was issued 45 minutes earlier than the one issued by GOES satellites.

Published: November 2023

The inner slope (γ
DM) of the dark matter (DM) density profile of cosmological halos carries information about the properties of DM and/or baryonic processes affecting the halo gravitational potential. Cold DM cosmological simulations predict steep inner slopes, γ
DM ≃ 1. We test this prediction on the MACS J1206.2-0847 cluster at redshift z = 0.44, whose DM density profile has been claimed to be cored at the center. We determine the cluster DM density profile from 2 kpc from the cluster center to the virial radius (∼2 Mpc), using the velocity distribution of ≃500 cluster galaxies and the internal velocity dispersion profile of the Brightest Cluster Galaxy (BCG), obtained from VIMOS@VLT and MUSE@VLT data. We solve the Jeans equation of dynamical equilibrium using an upgraded version of the MAMPOSSt method. The total mass profile is modeled as a sum of a generalized Navarro–Frenk–White profile that describes the DM component, allowing for a free inner slope of the density profile, a Jaffe profile that describes the BCG stellar mass component, and a nonparametric baryonic profile that describes the sum of the remaining galaxy stellar mass and of the hot intra-cluster gas mass. Our total mass profile is in remarkable agreement with independent determinations based on X-ray observations and strong lensing. We find

To measure oxygen abundances, we exploit Integral Field Spectroscopy data from the GASP and MaNGA surveys, photoionization models generated with the code Cloudy and the code Nebulabayes to compare models and observations. In particular, we build Cloudy models to reproduce line ratios induced by photoionization from stars, AGN, or a contribution of both. We find that the distributions of metallicity and [O iii] λ5007 luminosity of galaxies undergoing RPS are similar to the ones of undisturbed galaxies. Independently of the RPS, we do not find a correlation between stellar mass and AGN metallicity in the mass range

Published: November 2023

We present spatially resolved gas kinematics, ionization, and energetics of 11 type 1 and 5 type 2 active galactic nuclei (AGNs) with strong ionized gas outflows at z <0.3 using Gemini Multi-Object Spectrograph Integral Field Unit data. We find a strongly blueshifted region in [O iii] velocity maps, representing an approaching cone in biconical outflows, and blueshifted and redshifted regions in Hα velocity maps, which show gravitationally rotating kinematics. AGN photoionization is dominant in the central region of most targets, and some of them also show ring-like structures of LINER or composite that surround the AGN-dominated center. Following our previous studies, we kinematically determine outflow sizes by the ratio between [O iii] and stellar velocity dispersion. Outflow sizes of type 1 AGNs follow the same kinematic outflow size–[O iii] luminosity relation obtained from the type 2 Integral Field Unit sample in Kang & Woo and Luo (updated slope 0.29 ± 0.04), while they are limited to the central kiloparsec scales, indicating the lack of global impact of outflows on the interstellar medium. Small mass outflow rates and large star formation rates of the combined sample support that there is no evidence of rapid star formation quenching by outflows, which is consistent with the delayed AGN feedback.
Screening Earth Analog Exoplanets on the Basis of a Predicted Nitrogen over Phosphorus Ratio
Authors: Toulhoat Hervé
Published: November 2023

Since the first discovery in 1995, data for over 5300 exoplanets have been documented in the NASA archive, revealing a vast diversity. Identifying life-enabling analogs of the Earth among this rapidly expanding catalog is of major interest. The stability of liquid water at the planetary surface defining the concept of the habitable zone (HZ) around the host star, may be necessary for the emergence of life as we know it but not sufficient. The practically constant atomic ratio nitrogen:phosphorous = 16:1 in oceanic surface layers of our planet Earth was discovered by Redfield in 1934. It corresponds to phytoplanktonic biomass in suspension and appears optimal to fertilize phytoplankton development and therefore the food pyramid of marine life. Loladze and Elser have shown that it corresponds to a homeostatic protein:RNA ratio and is therefore “rooted in the stoichiometry of the foundational structures of life.” I show that according to the recent theory of the chemical differentiation of planets, this optimal ratio is also an intrinsic chemical property of our planet Earth uniquely determined in the solar system by its average orbital radius. On that basis, I propose a criterion of fertility within the HZ of a stellar system, which when applied to screen the public database allows us to sort out an extended list of up to 74 Earth analogs. The latter and its future extensions could provide priority targets for focused detection techniques.
Disk Cooling and Wind Lines as Seen in the Spectral Line Evolution of V960 Mon
Authors: Carvalho Adolfo , Hillenbrand Lynne , Seebeck Jerome
Published: November 2023

We follow up our photometric study of the postoutburst evolution of the FU Ori object V960 Mon with a complementary spectroscopic study at high dispersion that uses time series spectra from the Keck/HIgh Resolution Echelle Spectrograph. Consistent with the photometric results reported in Carvalho et al., we find that the spectral evolution of V960 Mon corresponds to a decrease in the temperature of the inner disk, driven by a combination of a decreasing accretion rate and an increasing inner disk radius. We also find that although the majority of the absorption lines are well matched by our accretion disk model spectrum, there are several strong absorption line families and a few emission lines that are not captured by the model. By subtracting the accretion disk model from the data at each epoch, we isolate the wind and outflow components of the system. The residuals show both broad and highly blueshifted profiles, as well as narrow and only slightly blueshifted profiles, with some lines displaying both types of features.
ALMA 400 pc Imaging of a z = 6.5 Massive Warped Disk Galaxy

We present 0.″075 (≈400 pc) resolution Atacama Large Millimeter/submillimeter Array (ALMA) observations of the [C ii] and dust continuum emission from the host galaxy of the z = 6.5406 quasar, P036+03. We find that the emission arises from a thin, rotating disk with an effective radius of 0.″21 (1.1 kpc). The velocity dispersion of the disk is consistent with a constant value of 66.4 ± 1.0 km s−1, yielding a scale height of 80 ± 30 pc. The [C ii] velocity field reveals a distortion that we attribute to a warp in the disk. Modeling this warped disk yields an inclination estimate of 40.°4 ± 1.°3 and a rotational velocity of 116 ± 3 km s−1. The resulting dynamical mass estimate of (1.96 ± 0.10) × 1010
M
⊙ is lower than previous estimates, which strengthens the conclusion that the host galaxy is less massive than expected based on local scaling relations between the black hole mass and the host galaxy mass. Using archival MUSE Lyα observations, we argue that counterrotating halo gas could provide the torque needed to warp the disk. We further detect a region with excess (15σ) dust continuum emission, which is located 1.3 kpc northwest of the galaxy’s center and is gravitationally unstable (Toomre Q < 0.04). We posit this is a star-forming region whose formation was triggered by the warp because the region is located within a part of the warped disk where gas can efficiently lose angular momentum. The combined ALMA and MUSE imaging provides a unique view of how gas interactions within the disk–halo interface can influence the growth of massive galaxies within the first billion years of the Universe.

Five new orchid species from southwestern China’s Yunnan Province and the Tibetan Autonomous Region, Neottia lihengiae, Neottia chawalongensis, Papilionanthe motuoensis, Gastrochilus lihengiae, and Gastrochilus bernhardtianus, are described and illustrated. To confirm their identities, and to resolve phylogenetic relationships, we sequenced the complete plastomes of these taxa with their congeneric species, adding new plastomes of three Neottia species, two Papilionanthe species and nine Gastrochilus species. Combined with published plastid sequences, our well-resolved phylogeny supported the alliance of N. lihengiae with the the N. grandiflora + N. pinetorum clade. Neottia chawalongensis is now sister to N. alternifolia, while P. motuoensis is closely related to P. subulata + P. teres. Conversely, phylogenetic analyses based on complete plastomes and plastid sequences showed inconsistent relationships among taxa in the genus Gastrochilus, but the two new species, G. lihengiae and G. bernhardtianus were supported by all datasets.

Un enjeu de recherche fondamentale et clinique
Authors: Lethimonnier Franck , Samuel Didier
Published: November 2023

La recherche en biothérapies et en bioproduction est au cœur de l’innovation médicale. Le transfert de ces découvertes vers la clinique et l’industrie est crucial. Depuis 2005, l’Inserm et les CHU ont créé des CIC dédiés, propulsant la France vers des avancées pionnières. En France, environ 100 équipes de recherche travaillent sur des biothérapies innovantes, et 50 autres se concentrent sur la bioproduction. Les avancées en édition génique et en biologie synthétique élargissent les possibilités. Les avancées en ARNm montrent également leur potentiel thérapeutique. La recherche est structurée avec des centres cliniques, des infrastructures de recherche et des accélérateurs de recherche technologiques. Pour encourager le transfert industriel, des « Intégrateurs Biothérapies – Bioproduction » ont été labellisés. La recherche française a progressé dans les biothérapies, avec des succès et des start-up innovantes. La prise de conscience récente de l’importance du domaine renforce cette dynamique.
Les enjeux de l’évaluation thérapeutique des biothérapies : focus sur les médicaments de thérapie innovante
Authors: Bartoli Fabienne , Baba Joachim , Ghabri Salah
Published: November 2023

Porteur d’espoir thérapeutique, les médicaments de thérapie innovante (MTI) se distinguent des autres médicaments classiques par leur modalité d’administration en prise unique visant à guérir une pathologie chronique. Au-delà de la promesse de guérison apportée par les MTI et des prix unitaires revendiqués bien souvent très élevés, ces médicaments présentent des enjeux importants pour le processus d’évaluation et de tarification du système de soins français car la démonstration de leur efficacité est bien souvent complexifiée par de très nombreuses incertitudes. Face à l’émergence des MTI sur le marché français, la Haute Autorité de Santé (HAS), agence responsable de l’accès au remboursement des technologies de santé, est pleinement engagée dans l’évaluation de ce type de médicament afin d’éclairer les décideurs publics concernés.
