Architecture Classification for Extrasolar Planetary Systems
Authors: Howe Alex R. , Becker Juliette C. , Stark Christopher C. , Adams Fred C.
Published: February 2025

This paper presents a classification framework for the architectures of planetary systems based on a complete survey of the confirmed exoplanet population. With nearly 6000 confirmed exoplanets discovered, including more than 300 multiplanet systems with N ≥ 3 planets, the current observational sample has reached a point where it is both feasible and useful to build a classification system that divides the observed population into meaningful categories. This framework provides a criterion for splitting planetary systems into inner and outer regimes, then further dividing inner systems into dynamical classes. The resulting categories include “peas-in-a-pod systems,” with uniformly small planets, and “warm-Jupiter systems,” with a mix of large and small planets, as well as “closely spaced systems” and “gapped systems,” with further subdivisions based on the locations of gaps and other features. These categories can classify nearly all of the confirmed N ≥ 3 systems with minimal ambiguity. We qualitatively examine the relative prevalence of each type of system, subject to observational selection effects, as well as other notable features, such as the presence of hot Jupiters. A small number of outlier systems are also discussed. Potential additional classes of systems yet to be discovered are proposed.

Published: February 2025

We present the first results of JWST Cycle 1 and 2 observations of Sgr A* using NIRCam taken simultaneously at 2.1 and 4.8 μm for a total of ~48 hr over seven different epochs in 2023 and 2024. We find correlated variability at 2.1 and 4.8 μm in all epochs, continual short-timescale (a few seconds) variability, and epoch-to-epoch variable emission implying long-term (~days to months) variability of Sgr A*. A highlight of this analysis is the evidence for subminute, horizon-scale time variability of Sgr A*, probing inner accretion disk size scales. The power spectra of the light curves in each observing epoch also indicate long-term variable emission. With continuous observations, JWST data suggest that the flux of Sgr A* is fluctuating constantly. The flux density correlation exhibits a distinct break in the slope at ~3 mJy at 2.1 μm. The analysis indicates two different processes contributing to the variability of Sgr A*. Brighter emission trends toward shallower spectral indices than the fainter emission. Cross-correlation of the light curves indicates for the first time a time delay of 3–40 s in the 4.8 μm variability with respect to 2.1 μm. This phase shift leads to loops in plots of flux density versus spectral index as the emission rises and falls. Modeling suggests that the synchrotron emission from the evolving, age-stratified electron population reproduces the shape of the observed light curves with a direct estimate of the magnetic field strengths in the range between 40 and 90 G and an upper cutoff energy, E

Published: February 2025

CzeV195 is a variable star discovered by Jaroslav Trnka (CzeV) in 2017 and classified at the Variable Star Index as a suspected EA-type variable star. The SSV-UAI-GRAV research section of the Unione Astrofili Italiani, undertook an observing campaign with ground-based telescopes in 2024 June and July. The star turned out to be an eclipsing variable of the EA type with a period of 0.604905 days. It was possible to detect an oscillation between the primary and secondary minima, typical of chromospherically active stars such as BY Draconis. Thanks to Zwicky Transient Facility and All-Sky Automated Survey for Supernovae photometry, ourbursts typical of UV Cet eruptive stars were detected. Czev195 was ultimately classified after our studies as an EA+BY+UV.

Published: February 2025

Here, we describe and illustrate a new monospecific genus of Compositae, Ovicula biradiatagen. et sp. nov., from the Chihuahuan Desert in Big Bend National Park, Texas. Ovicula biradiata is a very locally abundant, yet range-limited, spring annual herb found in coarse calcareous alluvium. Based on its pistillate ray florets, pappus of hyaline, aristate scales, tomentose foliage and slightly saucer-shaped to flat, epaleate receptacle, we determine that the new species has affinities with the Helenioid subtribe Tetraneurinae in the Heliantheae alliance. Molecular phylogenetic analysis of nrDNA (ITS) sequence data supports the phylogenetic position of Ovicula biradiata within the subtribe Tetranuerinae, where it is resolved as the sister lineage to the genus Psilostrophe. We also present detailed habitat information, high-resolution images captured using a dissecting microscope and scanning electron micrographs of vegetative and reproductive characters of Ovicula biradiata and related taxa, as well as provide an updated key to the genera of Tetraneurinae. Finally, we discuss the significance of this remarkable discovery for community science, biodiversity exploration and plant conservation in the Chihuahuan Desert.
Les carbapénèmases chez Pseudomonas aeruginosa : quand et comment les détecter ?
Authors: Paulais Thierry , Fournier D.
Published: February 2025

En France, environ 20 % des souches cliniques de Pseudomonas aeruginosa sont résistantes à l’imipénème. Parmi celles-ci, 5 % expriment une carbapénèmase hydrolysant à divers degrés l’ensemble des β-lactamines à l’exception de l’aztréonam. Les carbapénèmases retrouvées chez P. aeruginosa appartiennent majoritairement (≈ 90 %) à la classe B de Ambler avec notamment les enzymes de types VIM (70-80 %) et IMP (5-15 %). Rares jusqu’au début des années 2010, les carbapénèmases de classe A représentent aujourd’hui 10 % de l’ensemble des carbapénèmases identifiées chez P. aeruginosa en France. Cette évolution a des conséquences sur le choix des tests de détection à utiliser au laboratoire. Le dépistage des souches productrices de carbapénèmase (PAPC) est cependant un prérequis pour la mise en place de mesures d’hygiène. Leur application doit permettre de limiter la diffusion des souches multirésistantes ayant un impact sur l’efficacité des antibiotiques. Maîtriser la circulation de ces souches, c’est aussi réduire le risque de transfert de gènes de résistance vers les entérobactéries.
Couverture du dépistage du cancer du col de l’utérus en France, 2012-2017
Authors: Djezou Wadjamse Beaudelaire , Hamers F. F.
Published: February 2025

Introduction – Le Programme national de dépistage organisé (PNDO) du cancer du col de l’utérus (CCU), en cours de déploiement depuis 2018, a pour objectif d’augmenter la couverture du dépistage pour atteindre 80 %, de réduire les inégalités d’accès à ce dépistage et de diminuer de 30 % l’incidence et la mortalité par CCU à 10 ans. Disposer d’estimations fiables de la couverture du dépistage du CCU avant la mise en place du PNDO CCU est essentiel pour mesurer l’impact de ce programme. Méthodes – En France, le dépistage du CCU repose actuellement sur la réalisation d’une cytologie (frottis cervico-utérin – FCU) tous les tois ans pour les femmes âgées de 25 à 65 ans. Le taux de couverture du dépistage triennal a été calculé à partir des données de l’Assurance maladie, pour l’ensemble des femmes de 25-65 ans et par classe d’âge quinquennale, pour la France entière et par région et département, pour la période 2015-2017 ainsi que pour les trois périodes triennales glissantes précédentes depuis 2012. Résultats – Parmi les 17,8 millions de femmes âgées de 25 à 65 ans résidant en France, 10,4 millions avaient réalisé un FCU au cours de la période 2015-2017, soit un taux de couverture national de 58,7 %. La couverture diminue de manière importante avec l’âge à partir de 50 ans pour tomber à 44,2 % chez les femmes de 60-65 ans. Les taux nationaux globaux et par âge étaient relativement stables depuis 2012. Les données révèlent d’importantes disparités géographiques, avec des taux variant de 42 % à 68 % et des taux particulièrement faibles dans les départements et régions d’outre-mer, à l’exception de La Réunion. Conclusion – Le suivi des tendances de la couverture du dépistage du CCU devrait permettre de mesurer le progrès du PNDO CCU vers ses objectifs d’amélioration de la couverture et de réduction des disparités d’accès à ce dépistage.

Balancing Public Safety and Individual Rights in AI-Driven Public Administration in Nigeria
Authors: Akindipe Dayo , Lalude Olalekan Moyosore
Published: February 2025

The chapter examines the complex ties among privacy, surveillance, and public safety in today's world of AI-driven governance. The chapter will further examine what happens when a data-driven decision-making process works without transparency in Nigeria. Historically, those in authority have had an easier time keeping power when the decision-making process is hidden from the citizens. It will outline compelling strategies for mitigating the privacy risks that come with using AI in law enforcement, such as strong democratic oversight, the use of AI in a “data minimized” way, and the design of AI systems that ensures privacy is maximized. The chapter concludes by arguing that these strategies—and the informed, equitable future they make possible—are better than the alternative: a society governed by AI systems that infringe on individual rights and are not safe or secure.

Authors: Tushar  , Pradhan Nandita , Jaiswal Pooja
Published: February 2025

This chapter examines robust beamforming to increase power economy and reliability in magnetic-based wireless power transfer with many transmitters and receivers while accounting for MII imperfection. Transfer learning saves energy and improves efficiency in wireless communications by learning from prior tasks using correlation and similarity information. Since CSI procurement takes energy, its benefits gradually drop as power driven gadgets increase, yet spread. With system stability, channel state information techniques expand power insurance. ISWPT's integrated operation decreases system size, hardware cost, power consumption, and spectrum, enabling 6G wireless networks. Reconfigurable intelligent surfaces in wireless power transfer systems and designs can optimize energy efficiency by addressing multi-user circumstances and power distribution. Using simultaneous lightwave information and power transfer to combine EH and data transmission is fascinating and matures efficiency.

Published: February 2025

The 6G wireless communication technology is the successor to the 5G cellular-based technique. It is aimed at the increased bandwidth and higher dimensions of data transmission with the measurement of less than one microsecond of latency communication. Artificial Intelligence (AI) is pivotal in establishing computational and intelligence infrastructure, data storing, transmission, and decision-making. With the increased frequencies of 6G, sampling rates will surge beyond those achievable with 5G (Fifth Generation). Access points will gain the capacity to serve multiple clients through orthogonal frequency-division multiple access concurrently. The expected spectrum of communication using 6G is up to terahertz (THz). Artificial Intelligence (AI) guides Quality of Service (QoS) in 6G communication. This chapter covers a high-level overview of the role of AI in 6G, architecture, protocols, transmission technologies, and applications.

In March 2021, the Nigerian Government approved Coronavirus 2019 (COVID-19) vaccines, including CHAd0x1 nCov-19, Ad26.Cov2.S, mRNA-1273 and BNT162b2. Many, including healthcare workers, expressed hesitancy due to potential adverse effects. We conducted an observational study to assess the adverse effects of post-vaccination.
We followed vaccinated and unvaccinated cohorts daily for 7 days and then weekly for 3 weeks. We compared adverse effects between groups.
Vaccinated participants were 21 times more likely to experience an adverse effect (Relative Risk, RR=21.30; 95% Confidence Interval, 95%CI=8.107-56.012) and 4 times more likely to experience systemic adverse effects (RR=3.97; 95%CI=1.70-9.27) when compared to unvaccinated participants. Female participants were significantly associated with the development of both local and systemic adverse effects, X2=77.9% (p≤0.001) and X2=47.1% (p=0.0037), respectively. Up to 81.6% of second-dose vaccine recipients compared to 68.4% of first-dose vaccine recipients developed at least one adverse effect, X2=5.25 (p=0.071). None of the vaccinated participants developed severe adverse effects during the study period.
Adverse effects from COVID-19 vaccination are common, but generally safe and tolerable. Females play a significant role in reporting adverse effects. Both systemic and local adverse effects are expected to resolve within a few days post-vaccination.

Authors: Khurana Ashi , Agarwal Pradeep , Chauhan Lokesh
Published: February 2025

Background:

Cataract surgery is a widely performed procedure aimed at restoring visual acuity in individuals with cataracts. Evaluating the visual outcomes of these surgeries is essential for assessing surgical effectiveness and patient satisfaction. This study presents a clinical audit conducted at CL Gupta Eye Institute to analyze the visual outcomes of patients who underwent cataract surgery, aiming to identify trends and areas for improvement.

Methodology:

A retrospective medical chart review was conducted on patients who underwent cataract surgery at CL Gupta Eye Institute between January 20 and December 21. The study included 2713 randomly selected patients, and data on demographics, preoperative visual acuity, surgical details, postoperative visual outcomes, and complications were collected and analyzed.

Results:

Among the 11,124 cataract surgeries performed during the study period, 2713 patients were included in the analysis. The average age of patients was 57.9 years, with a slight male predominance. Preoperatively, 2.6% of patients had vision <6/60 in both eyes, while postoperatively, 93.4% achieved a good visual outcome (>6/12). However, 2.3% experienced poor visual outcomes according to WHO standards. Complications necessitating a second surgery were observed in 25 patients, with subsequent visual improvement in 17 cases.

Conclusion:

The clinical audit demonstrates high rates of successful visual outcomes following cataract surgery at CL Gupta Eye Institute, exceeding WHO standards. The findings underscore the effectiveness of surgical interventions and highlight the areas for continued quality improvement. Planning for a re-audit in July 2024 will facilitate the assessment of long-term trends and enable the institute to maintain its commitment to delivering optimal visual outcomes for patients undergoing cataract surgery.

Authors: Cavenaghi-Altemio Angela Dulce , Fonseca Gustavo Graciano
Published: February 2025

Fish industry is innovating to create versatile food products from fish valorization, by adding value to fish waste. The aim of this study was to utilize mechanically separated meat (MSM) of spotted sorubim (Pseudoplatystoma coruscans), a by-product obtained from processing fish carcasses, to develop fish kibbeh added of flaxseed, to create a functional food. Fish kibbeh formulations contained bulgur flour (F1), a mixture 1:1 of bulgur flour and flaxseed (F2) or flaxseed (F3). pH, shear force (SF), microbiology, sensory attributes and acceptance were evaluated. Results of SF showed that the higher the bulgur wheat content, the harder the texture (12.06 N for T1; 4.02 N for F3) due to differences in the granulometry of the flour. Color, odor and taste did not differ (p>0.05) between F1 and F2, but all parameters differed (p<0.05) from F3. Texture of F1 and F3 differed (p<0.05) from each other, but texture of F2 did not differ (p>0.05) from F1 and F3. Average scores of the sensory attributes ranged from 5.47 to 7.80. F1 and F2 presented acceptances indexes above 70%. Purchase intentions were 80, 39.9, and 23.3% for F1, F2, and F3, respectively. Despite F2 demonstrated similar sensory scores to F1, the lower purchase intention indicates that the formulation requires further refinement to become commercially viable.

Published: February 2025

A Rocky Mountain spotted fever (RMSF) epidemic has spread through the state of Baja California, Mexico over the last decade and a half, beginning in Mexicali, and subsequently to Tijuana and to Ensenada by 2018. In October of 2022, we surveyed dogs and homes in randomly selected Áreas Geoestadisticas Básicas (AGEBs) with and without reported human cases. Brown dog ticks (Rhipicephalus sanguineus sensu lato) were found on 33.9% of dogs and in the yards of 23.6% of homes. Homes from AGEBs with cases had over a 6-fold increased odds of ticks being present in the yard than AGEBs without reported cases. Both dogs that were permitted to roam and the presence of roaming dogs in the neighborhood were strongly associated with tick infestation of dogs and homes. No ticks or blood samples were polymerase chain reaction-positive for Rickettsia (R.) rickettsii, the causative agent of RMSF, although 54.6% of dogs were seropositive for spotted fever group rickettsiae, and 17.4% were seropositive for typhus group rickettsiae. R. massiliae and R. felis were detected in eight (1.3%) and 29 (4.8%) ticks, respectively; and R. felis was also detected in eight (4.6%) dog blood samples. Although the pathogenic potential of these other rickettsial species and their role in RMSF transmission remains unclear, our data on tick burdens in dogs and homes as risk factors for RMSF exposure provide further support to the pivotal need to reduce tick burdens and the numbers of roaming dogs to successfully manage the RMSF epidemic in northern Mexico.

L’étude a été initiée pour améliorer la rentabilité économique des engrais dans un contexte d’appauvrissement continu des sols dans le  périmètre rizicole de Sindou à l’Ouest du Burkina Faso. Ainsi, l’efficacité des doses variées de NPK et de l’urée sur les performances  agronomiques du riz de variété FKR84 y a été examinée. Le dispositif utilisé a été du type split –plot avec trois répétitions. Les parcelles  principales étaient représentées par les trois doses de NPK (NPK1, NPK2, NPK3), respectivement (150, 200 et 250) kg.ha.-1. Les doses  NPK1, NPK3 ont été fractionnées en 100 kg.ha-1 et 200 kg.ha-1 appliquées au repiquage et 50 kg.ha-1 apportée à l’épiaison contre 200  kg.ha-1 de NPK2 appliquée en une dose unique. Chaque parcelle principale a été subdivisée en quatre parcelles secondaires  correspondantes aux doses d’urée (U1, U2,U3 et U4).La combinaison des doses de NPK et d’urée a permis d’obtenir douze traitements:  dont la combinaison NPK2*U1 était le témoin. Les parcelles U1, U2 ont reçu 50 kg.ha-1d’urée perlée 15 jours après le repiquage (JAR)  contre 72 kg.ha-1 d’USG au 10ème JAR pour U3 et U4. A l’épiaison, U2 et U4 ont reçu 50 kg.ha-1 d’urée perlée contre 50 kg.ha-1 de NPK pour les parcelles principales NPK1 et NPK3. Les résultats ont montré que le traitement NPK3*U1 a donné un rendement en paddy de  5004 kg.ha-1 soit un taux d’accroissement de plus 53% par rapport au témoin (3262 kg.ha-1 ), une efficacité agronomique (EAF) de 34%,  de générer une marge brute de 3451 FCFA.ha-1 pour un surplus d’un kilogramme de NPK. Ce traitement est économiquement rentable  (RV/C= 2) et pourrait être recommandé dans notre système de riziculture.

La cocoteraie ivoirienne est de plus en plus menacée par les attaques des insectes nuisibles dont celle de la punaise Pseudotheraptus  devastans. Pour la lutte contre ce ravageur tout en préservant l’environnement et la santé des consommateurs, des plantes à effet  insecticide sont préconisées. L’objectif de cette étude était de connaître les différentes molécules de ces plantes à effet insecticide  utilisées sur la Station de recherche Marc Delorme de Port-Bouët dans la lutte contre le ravageur Pseudotheraptus devastans. Ainsi, trois  plantes locales (Ocimum gratissimum, Ricinus communis et Tephrosia vogelii), ont été l’objet de notre étude. Les feuilles vertes de  chaque plante ont été séchées à l’étuve à 35°C pendant 5 jours avant d’être réduite en poudre fine. Les extraits des trois plantes ont été  obtenus après macération séquentielle à température ambiante dans des solvants organiques (hexane, dichlorométhane, acétate  d’éthyle et le méthanol), pendant 48 heures par solvant de 200 grammes de chaque poudre fine, suivie d’une filtration sur papier  Wattman et évaporation au rotavapor. Le méthanol a permis d’obtenir les rendements les plus élevés, soit : 12,85% ; 14,63% ; 15,41%,  respectivement pour O. gratissimum, R. communis et T. vogelii. Le screening phytochimiques réalisés sur 4 extraits (hexanique, dichlorométhanolique, acétate éthylique et méthanolique) de chaque plante a révélé que celles-ci contiennent des stérols, des  polyterpènes, des polyphénols, des alcaloïdes et des sucres réducteurs. Des quatre (4) solvants utilisés pour les extractions, le méthanol  est le solvant qui a produit les plus grandes quantités de masse extraite.
Impact de la production cotonnière dans les exploitations agricoles sur les cultures vivrières au Bénin en Afrique de l’Ouest : Revue Systématique
Authors: Olaitan Aliou , Akueson Adoté Hervé Gildas , Yabi Jacob A.
Published: February 2025

Cette revue systématique visait à explorer l'impact de la production de coton dans les ménages agricoles sur les cultures vivrières au  Bénin, en Afrique de l'Ouest. La motivation de cette étude est née de l'inquiétude croissante face à la concurrence entre les cultures de  rente et les cultures vivrières, une problématique cruciale pour la sécurité alimentaire dans la région. L'étude cherchait à comprendre  comment l'expansion de la culture du coton pourrait affecter la disponibilité et la productivité des cultures vivrières dans les ménages  agricoles. Le problème abordé est celui du déséquilibre potentiel dans l'utilisation des terres et l'allocation des ressources, qui pourrait  compromettre la durabilité de la production alimentaire. Les données de cette revue ont été collectées à partir de la base de données  Scopus en utilisant l'équation de recherche suivante : (Production de coton " OU " Culture du coton " OU " Coton") OU TITLE-ABS-KEY  ("Exploitation agricole " OU " Ménages agricoles") ET ("Afrique de l'Ouest"). Un total de 1 211 documents exportés de Scopus ont été  soumis à une analyse bibliométrique avec les logiciels Perish 8, VOSviewer et Excel. L'analyse des publications annuelles a révélé que la  majorité des articles ont été publiés entre 2000 et 2021. Il est apparu que les auteurs ayant un bon taux de réputation étaient cités en  moyenne 64 fois par an. 84% des documents les plus publiés étaient des articles scientifiques ; les domaines scientifiques avec le plus de  publications étaient les sciences agricoles (30%), suivis des sciences de l'environnement (14%) et des sciences sociales (12%). Dans  l'ensemble de la base de données, l'indice h était de 188, indiquant que les documents scientifiques étudiés avaient été cités au moins  une fois dans une revue scientifique. Cependant, l'indice ha était faible (24), suggérant qu'il y avait une marge d'amélioration à l'avenir.  Cette disparité reflète les niveaux de citation inégaux entre les différents documents et auteurs, ce qui pourrait s'améliorer avec une  augmentation de la recherche et des publications dans ce domaine.

Published: February 2025

Extensive use of such fungicides leads to Cu diffusion in most soils and increases risk of Cu phytotoxicity for the tropical gum tree  (Sterculia setigera) grown in these soils. A pot experiment was set to examine the effect of Arbuscular Mycorrhizal Fungus (AMF),  Rhizophagus fasciculatus, and soil copper levels content on mineral status of the tropical gum tree Sterculia setigera. Plants were grown  in soil with different Cu levels (0, 200, 400, 600 and 800 mg.kg-1 ). Control plants (C) were found to have survival rate were of 40% at 600  mg.kg-1 Cu. Inoculated plants (T) on their part had a survival rate of 100% on Cu contaminated soils up to 600 mg.kg-1 Cu. However, at  800 mg.kg-1 Cu level, 100% of the plants died. Root colonization rates (7.4%) were significantly lower at 600 mg.kg-1 Cu. In contaminated  soil, higher mycorrhizal colonization was measured at 0, 200, and 400 mg.kg-1Cu addition levels. AMF-inoculated plants had higher K, P,  N, Ca, Mg and Cu concentrations than uninoculated plants. In mycorrhized plants, nutrient concentrations increased with the increasing  levels of soil Cu and were higher than those of the non-mycorrhized plants. Unlike Na, the uptake of K increased in shoot tissues of  mycorrhizal plants with the increasing levels of Cu. Results suggested that S. setigera associated with AM fungus Rhizophagus  fasciculatus had the potential to survive and to grow under moderately Cu contaminated soil system.

Arsenic analysis is essential, as it is a carcinogenic compound according to the International Agency for Research on Cancer (IARC).  Currently, there are techniques based on powerful equipment that allow quantification with very low detection limits as Inductively  Coupled Plasma (ICP). However, groundwater pollution issues are not respectful of equipment’s availability or local financial resources.  Furthermore, standardised methods on the market are not sufficiently accessible to laboratories in developing countries that use them as  a reference, and only methods available in reference books are commonly used. We have therefore modified the available colorimetric  method, which has a quantification limit of 25 µg/L, to achieve a detection limit of 5 µg/L, which is lower than the WHO  standard, in order to further identify groundwater samples that would present a high health risk due to consumption. Colorimetric  method based on silver diethyldithiocarbamate has been used. The effects of various parameters such as arsenic initial concentration (up  to 800 µg/L), volume of solution (35-120 mL) were evaluated on arsine quantification. The results reveal that for concentrations  below 25 µg/L, a test volume of 100 mL is sufficient to measure arsenic concentrations in water up to 5 µg/L. However multiple extraction  is indicated in the less concentrated samples (<5 µg/L) for reliable quantification. Experiments performed with the previously used zinc  shots show that washing with appropriate mixture several times and drying allows arsenic quantification with 10% loss of zinc activity

Published: February 2025

La présente étude se propose de déterminer les niveaux et les risques potentiels pour la santé des pesticides chimiques de synthèse du  miel produit dans la Commune cotonnière de Banikoara. Ainsi, de 2021 à 2022, vingt-quatre (24) échantillons de miels multifloraux  prélevés dans les localités de Kérémou et de Founougo ont été analysés et quantifiés par chromatographie en phase gazeuse couplée à  la spectrométrie de masse. Les résultats ont montré que quels que soient la période de sa récolte, le lieu où le type de ruche de  prélèvement, le miel contenait des résidus de pesticides chimiques. Celui récolté en novembre contenait plus de résidus de pesticides et  de matières actives dangereuses que celui de mars. Les trente-cinq (35) molécules actives détectées dans le miel de novembre étaient  réparties en seize (16) familles chimiques dont les plus représentatives étaient les organophosphorés (17,14%), les pyréthrinoïdes  (17,14%), les triazoles (14,29%), les triazines (11,43%) et les néonicotinoïdes (8,57%). Les quotients de risque sanitaire les plus élevés avec  la lambda-cyhalothrine pour les adultes (1,29E-04) et les enfants (1,33E-04) étaient inférieurs à 1. Bien que ne présentant pas de risques  sanitaires, la surveillance du miel doit être de mise.

Authors: Barbi Lucas , Coelho Paloma , Profeta Zélia
Published: February 2025

O objetivo do artigo é analisar como a categoria território foi operacionalizada nas intervenções participativas de enfrentamento à dengue, zika e chikungunya a partir de uma revisão integrativa da literatura científica de 2016 a 2020. Os artigos foram selecionados por meio da Biblioteca Virtual em Saúde. Como critérios de inclusão, foram escolhidos os artigos indexados às bases LILACS e Medline, escritos em espanhol, português e inglês e disponíveis na íntegra sobre intervenções que incluíam a participação da comunidade em alguma etapa do seu desenvolvimento. Ao todo, 20 artigos foram classificados em 4 tipos, conforme quanto à natureza das intervenções: educação e participação comunitária, medidas de controle ou vigilância vetorial, Manejo Integrado de Vetores e desenvolvimento e teste de tecnologias. A análise evidenciou que o território, quando abordado nas produções selecionadas, foi raramente considerado como uma dimensão explícita, limitando-se em geral à divisão em clusters ou subdivisões administrativas. Por fim, a análise da participação e da mobilização social aponta que o poder de decisão concentrado nos organizadores das intervenções, dificultando a efetivação de ações verdadeiramente sustentáveis para o enfrentamento das três doenças analisadas.

Authors: Uribe Juan Mancilla , Cáceres Felipe Estrada , Daziano José Venegas
Published: February 2025

La osteonecrosis de maxilares relacionada a medicamentos (MRONJ) es una complicación grave asociada al uso de bisfosfonatos y denosumab mayormente, esta es más prevalente en pacientes oncológicos o con osteoporosis. La incidencia de MRONJ varía según el tipo de tratamiento, siendo más prevalente en pacientes tratados con medicamentos antirresortivos endovenosos. Actualmente, no existe un tratamiento definido para la MRONJ, particularmente en sus etapas avanzadas, lo que representa un desafío clínico significativo. La teriparatida, es un análogo de la hormona paratiroidea, ha surgido como una terapia innovadora al promover el remodelado óseo, aumentar la formación de hueso y favorecer la curación de diversas lesiones Oseas. Los estudios reportan tasas de éxito del 45.4% en lesiones asociadas a MRONJ tras un tratamiento de 8 a 12 semanas, junto con mejoras en los marcadores óseos de los pacientes. Sin embargo, su uso presenta limitaciones, como su costo elevado, necesidad de una administración subcutánea y riesgo de efectos adversos al largos plazo. Aunque la teriparatida es prometedora como una terapia adyuvante, se requieren más investigaciones para validar su efectividad y seguridad, estableciendo su lugar en las guías de tratamiento para MRONJ.

​Este estudio se centra en el diseño e implementación de un sistema basado en el Internet de las Cosas (IoT) para monitorear la calidad del aire en el centro de Quevedo (Ecuador), que utilizando sistemas embebidos como Arduino Mega y Raspberry Pi, se integraron sensores específicos, el PMS3003 para material particulado (PM2.5) y el MQ-7 para monóxido de carbono (CO). Estos dispositivos permitieron recopilar datos en tiempo real sobre los contaminantes, los cuales fueron procesados y almacenados en la base de datos InfluxDB, con visualización a través de la plataforma Grafana. El análisis de datos se realizó durante ocho meses, cuyos niveles máximos de CO alcanzaron 49.28 ppm, mientras que las concentraciones de PM2.5 registraron un máximo de 5.35 ppm. Estas cifras, aunque significativas, se encontraron por debajo de los niveles de alerta establecidos por la normativa nacional y la Organización Mundial de la Salud (OMS), indicando que no representan un riesgo crítico para la salud humana. Sin embargo, se identificaron patrones relacionados con factores climáticos y la actividad vehicular. Los niveles de contaminantes aumentaron durante períodos de mayor radiación solar y baja ventilación, mientras que disminuyeron en condiciones de viento y menor tráfico vehicular. El sistema mostró ser una herramienta eficiente para el monitoreo ambiental, destacándose por su bajo costo y capacidad de adaptación. Se recomienda ampliar la cobertura del sistema en otras áreas urbanas y promover la educación ciudadana sobre el impacto de las emisiones vehiculares en la calidad del aire. Este proyecto demuestra el potencial de las tecnologías IoT para enfrentar desafíos ambientales en contextos urbanos.

This study employs a dynamic approach to investigate the influence of blockchain integration on port export procedures in Algeria. This study aims to examine in detail the advantages and potential benefits of blockchain technology in this context. In addition, it seeks to identify and analyze the practical implications for the key stakeholders in the sector, including port authorities, freight forwarders, consignees, and maritime customs. A random sample was selected from the port companies in Ghazaouet (western Algeria) and Annaba (eastern Algeria) to conduct the survey. Of the 125 questionnaires distributed, five were rejected and ten were not collected, leaving 110 valid questionnaires for analysis. Therefore, the sample represents 88% of the target population and encompasses the categories concerned with using blockchain in the port export supply chain. The data collected was analyzed using the SPSS V27 statistical processing method. The results demonstrated a statistically significant effect of blockchain technology on export processes in the two port companies in Algeria.

Published: February 2025

La información relacionada a la eficacia de los tratamientos terapéuticos en el ámbito de las drogodependencias es limitada, pese a los esfuerzos de la administración pública en destinar recursos económicos. El presente artículo se ha desarrollado dentro de un análisis documental, metodología descriptiva – documental, es decir se inició la revisión de bibliografía variada, nacional e internacional, consultando artículos científicos, libros, revistas, manuales centrándose en el presente y pasado de los tratamientos para personas drogodependientes, en cada uno de los países investigados, se seleccionó los de mayor validez teórica con el objetivo de conseguir información precisa en cuanto a los tratamientos, modalidades y enfoques que se seleccionaron cognitivo conductual, humanista y sistémico utilizados en los centros, clínicas en países hispanohablantes. Una vez realizado el análisis de la bibliografía seleccionada en el artículo se evidenció que, en los países México y Perú que corresponden al 25% se empleó el enfoque cognitivo conductual, mientras que Chile y Costa Rica que corresponden al 25% emplearon la terapia humanista, de igual manera en España, Colombia y Guatemala que corresponden al 37.5% se abordó mediante el enfoque sistémico familiar, finalmente en Ecuador que corresponde al 12.5% dentro del Centro Especializado en el tratamiento a personas con consumo adictivo de alcohol y otras drogas (CETAD), se utilizó el enfoque integrativo. Una vez exploradas las diferentes modalidades de tratamiento, enfoques en cada país y contexto que se seleccionó dentro del artículo, se concluye que no existe un enfoque con una prevalencia significativa dentro de los tratamientos que se brindan en las diferentes entidades en el proceso terapéutico y rehabilitación a personas con consumo alarmante de drogas.
