Éléments pour la compréhension du fonctionnement de la tourbière de Jouvion à Saint-Donat (Puy-de-Dôme) [Some ecological aspects of the peat bog of Jouvion (Saint-Donat, Puy-de-Dôme, Central France)]
Authors: Goubet Pierre , Christophe Hervé , Boichut Philippe
Published: January 2025

La tourbière de Jouvion à Saint-Donat (Puy-de-Dôme) est un ancien haut-marais aujourd’hui en phase d’érosion — corrosion : microtopographie inexistante, talus et lagg manquants, tourbe tassée compacte et végétation turfigène absente. Le complexe tourbeux comprend 5 autres unités principales : un ensemble de prairies tourbeuses, un ruisseau coupant le haut-marais, une moliniaie à l’endroit d’une ancienne exploitation artisanale de tourbe, une zone de haut-marais très piétinée et un réseau de dépressions sur la partie sud du haut-marais. La topographie de surface et de subsurface, comparée aux modèles théoriques de développement des hauts-marais, permet de proposer que deux édifices distincts ont coexisté sur le site. Des propositions d’études complémentaires sont proposées pour tester cette hypothèse.
Flore et dynamique des végétations des Gorges de la Monne en 1996-2003. Eléments pour leur gestion patrimoniale / Flora and dynamic of the vegetation in the « Gorges de la Monne » since 1996-2003. Materiels for patrimony conservation and administration

Flora and dynamic of the vegetation in the «Gorges de la Monne» since 1996-2003. Materials for patrimony conservation and administration.

«Gorges de la Monne» is a «Site classé» as scheduled place of landscape interest. In addition, flora is very rich : about 500 vascular plants species have been recorded in 1996 and 2003, 31 species are remarkable, which 5 are protected in Auvergne or in France. Because of north or south orientation of the slopes, varied altitude and a context of sheltered climate, vegetations are very varied. Some of them are Eurpoean interest habitats (following directive 1992/43/CEE) as priority lime-tree ravines and alder forests along the Monne river. During the 1996-2003 period, the evolution of vegetations is principally caused by the 1999 december storm : pine-forests and some of oak-grove have suffered from the wind ; many trees are falled to the ground. Natural regeneration ends at very rich herbaceous populations and impenetrable bushs. A slow natural dynamic is observed in lawns, heats and bushs on south slope : in 7 years, senescence is observed in some heats with withered brooms ; occasionally, Calluna vulgaris heath have supplanted a Artemisia campestris vegetation ; and, perrennial gramineous Festuca filiformis has spreaded in a Aira praecox lawn. On south slopes near Randolle, maintenancy of sheeps grazing is necessary for maintaining the diversity of vegetations. Conservation managements and valorization of floristic patrimony are proposed.

Collybia fusipes root rot of Quercus robur L. and Q. petraea Liebl. in the forest of Bagnolet (Central France).

The fungus Collybia fusipes (Bull. : Fr.) Quél. is the cause of a root rot of Quercus robur L. and Q. petraea Liebl. in the forest of Bagnolet (Central France). The symptoms and the evolution of the disease over 15 years are described in a sessile oak (Quercus petraea) stand on a soil affected by an important waterlogging.
Les sources d’eaux minérales de Sainte-Marguerite (Puy-de-Dôme, France) / Mineral water springs at Sainte-Marguerite (Puy-de-Dôme, France)
Authors: Bonhomme Anne , Mercier Francine
Published: January 2025

Mineral waters field of Sainte-Marguerite are placed in border of the river Allier (Puy-de-Dôme, Massif central, France). Several springs have an authorization to exploit since 1894 but only two springs are bottled nowaday by Intermarché society. Studies realised since 1978 showed that carbogazeuses waters of Sainte-Marguerite are of type bicarbonate chlorinates sodic, the mineralization is acquiered in granitic rock and the CO2 is of deep origin ; the multiannual chemical follow-up of waters of one unexploited borehole in particular the isotopes of the strontium show the chemical constant of the water but leash to suppose the complexity of the field.
L’avifaune du puy Saint-Romain (Puy-de-Dôme, France), de ses pentes, et des zones humides à ses pieds / Bird species at the puy Saint-Romain (Puy-de-Dôme, France) and proximate wetlands
Authors: Dulphy Jean-Pierre , Tourret Pierre
Published: January 2025

La liste des espèces d’oiseaux visibles sur le puy Saint-Romain est donnée avec les milieux fréquentés (prairies, cultures, haies, bois) et les périodes (surtout le printemps). Cette liste est assez conséquente puisque environ 80 espèces ont été notées. Certaines sont très courantes, mais d’autres sont très rares, comme le Hibou Grand Duc, l’Autour des palombes et le Circaête Jean-le-Blanc. Par ailleurs, le puy se trouve en bordure de zones humides et de la rivière Allier, ce qui amène au minimum 20 espèces supplémentaires, dont certaines originales (oiseaux d’eau et Guêpier en particulier). Au final, grâce à la mosaïque de milieux présents, on peut considérer que le site est d’un intérêt certain pour l’avifaune.

Les pacages estivaux semi-naturels du domaine expérimental du Pachou sur la planèze basaltique du Cézallier (Landeyrat, Cantal) / Semi-natural summer pastures in experimental Pachou's domain on Cézallier basaltic table-land (Landeyrat in Cantal, Central France)
Authors: Frain Michel , Blanchetête André , Decuq Francis
Published: January 2025

Le domaine du Pachou est un site expérimental de l'I.N.R.A. de 80 ha comprenant une ancienne habitation estivale de pierre (buron). Le site d''une altitude de 1100 m est localisé dans un paysage ouvert constitué de prairies établies sur un sol volcanique légèrement acide (andosol) et pauvre en nutriments. Les prairies du domaine sont pacagées modérément par un troupeau de 70 vaches de race Salers ; elles ont en général gardé un caractère semi-naturel typique des pacages estivaux extensifs. Cinq associations végétales sont décrites : une association hygrophile près du ruisseau d'un vallon (Deschampsio cespitosae-Oenanthetum peucedanifoliae) relevant de l'alliance du Bromion racemosi ; une association mésophile (Lolio perennis-Cynosuretum cristati) sur un sol fertilisé dans les environs du buron et classée dans l''alliance du Cynosurion ; le mésophile Festuco rubrae-Cynosuretum cristati relevant de la même alliance et moins fréquenté par le bétail ; une association mésophile nouvelle Agrostio capillaris-Festucetum rubrae

du Lino-Gaudinion à deux strates et la plus étendue dans le site ; et une sous-association inédite pour le Cantal (Pulsatillo rubrae-Dactylorhizetum sambucinae gentianelletosum campestris) du Koelerio-Phleion occupe les pentes méridionales du vallon. Les végétations comprennent de nombreuses espèces oligotrophes ; certaines sont des plantes acidiphiles fréquentes dans la nardaie montagnarde. Les pacages se caractérisent par une certaine richesse floristique : 150 plantes sont reconnues en 2001-2003. Les espèces les plus remarquables sont recensées dans la prairie à anémone rouge et orchidées comme le rare botryche lunaire (Botrychium lunaria) signalé dans un complément pour la flore d''Auvergne, et des plantes peu communes : Gentianella campestris, Dianthus deltoides et Gymnadenia conopsea, signalées dans un autre complément. 20 autres espèces colonisent les environs et les dépendances ruinées du buron du Pachou, en particulier la très toxique grande ciguë (Conium maculatum) introduite par d'anciens résidants et utilisée dans la pharmacopée traditionnelle
Bilan hydrique du lac Pavin / Water balance of the lake Pavin

Published: January 2025

The water balance of lake Pavin is not closed with superficial inputs only, so sublacustrine inflow(s) were invoked in order to complete the budget. But until now both superficial inputs and outputs were themselves poorly constrained, and so the derived budget was not reliable. The aim of this paper is to improve the knowledge of the water budget of this lake. New and numerous data, which were acquired from May 2006 to February 2008 for 12 streams feeding the lake, lead to a mean annual input of 2160 ± 300 m3 d-1. Most of the superficial inputs (> 90 %) are located in the South-East shore of the lake. Moreover, the chemical composition of the superficial inflows (17 streams or springs) allows to distinguish at least 3 kinds of water inputs corresponding to 3 subterranean reservoirs. The surface water outflow (North shore), which was determined from a limnigraphe data set, is estimated to a mean value of 5720 ± 500 m3 d-1.

New 14C data (for dissolved inorganic carbon) allow to assess a mineral water input at c. a. 68 m depth. The modeling of the oxygen isotope composition (δ18O) of the water column gives a corresponding inflow estimated to 150 m3 d-1 and an evaporation rate to 300 m3 d-1. Moreover, temperature show some artifacts on some vertical profiles that can be attributed to a cold sublacustrine intrusion of superficial water type, from 53 m depth to 35 m depth depending on the period. A water discharge coming from the upper monimolimnion zone is identified, but its outflow is negligible. All these data allow to propose a global water budget. The water residence time in the monimolimnion is calculated to be about 90 years. A global modeling of the water column shows that the observed steady state of the deep layer can be achieved in more than two centuries. In addition, chemical budget is given for some dissolved elements.

Les forêts autour du lac Pavin : présentation historique (commune de Besse-et-Saint-Anastaise, Puy-de-Dôme) / History of forest around the lake Pavin (Besse-et-Saint-Anastaise, Puy-de-Dôme)
Authors: Lathuillière Laurent
Published: January 2025

Le lac Pavin est ceinturé de versants boisés qui pourraient donner l’impression au visiteur qu’il en a toujours été ainsi. Et pourtant, l’analyse des archives forestières transmises au fil des ans montre qu’il y a seulement deux siècles, les paysages bordant le lac étaient presque complètement déboisés. C’est en grande partie grâce à la volonté constante des forestiers de protéger les quelques bois existants au début du 19ème siècle, et de reconstituer des peuplements forestiers aptes à calmer les effets des éléments, à retenir les sols, et à fournir les produits dont les populations avaient besoin (charpente, chauffage), que les forêts que nous observons de nos jours ont été progressivement façonnées. Elles remplissent aujourd‘hui les fonctions multiples attendues par la société : production de bois, environnement, protection, accueil du public. Nous présentons au travers de documents d’archives les principales étapes de leur constitution et de leur évolution depuis 1800.

La Banne d’Ordanche et le plateau du Guéry ont une richesse botanique due à leur passé géologique et à la diversité géoclimatique. Cet article est l’occasion de découvrir, sur la Banne, la grande gentiane, objet d’une exploitation intense, l’haüyne, minéral bleu si discret qu’on a du mal à le trouver, le majestueux et protégé Lys Martagon, sous le Puy-Gros, la Drosera, vedette des sagnes et tourbières, carnivore pour pallier au manque d’azote, remarquable exemple d’adaptation à son milieu… Nous rêverons, en hiver, aux héros de Jack London autour du lac de Guéry avec les P’tits Loups de la Banne. Nous apprendrons l’histoire de la Malvialle et le siège du château de la Roche Sanadoire rapporté par Froissard, de la Ferrandaise qui faillit disparaître, du vol à voile qui eut, sur le plateau, son heure de gloire entre les deux guerres. Nous découvrirons aussi la richesse des estives sans lesquelles il n’y aurait pas de Bleu de Laqueuille, les champignons qui permettent d’associer les plaisirs de la promenade et de la découverte à ceux de la table, les coulées de la Banne qui servent de filtre à l’eau de Laqueuille.

En août 2011 a été effectué l’inventaire des mollusques continentaux de la RNN de Chastreix-Sancy. Le prélèvement de litière et son tamisage, la recherche à vue, la disposition de pièges Barber, de bâches et l’utilisation du troubleau ont permis la découverte de 39 espèces (36 gastéropodes et trois bivalves, cinq aquatiques et 34 terrestres). Il ressort que peu d’espèces sont présentes au delà de 1 600 m d’altitude. De plus, les hêtraies et les tourbières sont les milieux les plus riches.

The Sioule metamorphic sequence 75 years after J. Richard’s (1938) works

The Sioule metamorphic sequence is a classically studied area within the French Massif Central. A large number of studies is available, ranging from fundamental geology (geodynamics) or economic geology (ore deposits such as for example in the Échassières district). Successive generations of geologists followed each other in order to observe, describe and interpret the complex geological phenomenon that can be outlined within this sequence.

Materials for the study of the brambles and their close relatives (Rubus L., Rosaceae) : specimens of the herbarium of the Museum Henri-Lecoq (Clermont-Ferrand, France)

The herbarium of the Museum Henri-Lecoq (MHLCLFE) preserved a not yet studied collection of dried and mounted brambles and close relatives collected during the 19th century. Our paper gives the list of the Rubus species contained in this herbarium : 34 taxons among 198 specimens are identified ;

Rubus godronii Lecoq & Lamotte was not found in this Henri Lecoq’s herbarium, but there is a Rubus wahlbergii Arrh. collected near Nancy (France) and given by Godron, but unfortunately Martial Lamotte identified it as a Rubus dumetorum Weihe & Nees ; further investigation should show if this sample may be a syntype of the Godron’s bramble. The geographical origins of the specimens are Europe, mainly from France and the Massif Central. Some famous batologists participated to this plant collection, such as D. A. Godron, H. Lecoq, M. Lamotte, J. Héribaud and E. Gatien, H. Sudre and D. Tuczkiewicz.

Contribution to the knowledge of terrestrial isopods of the Auvergne (Crustacea, Isopoda, Oniscidea)

The authors deliver an annotated list of the twenty-five species of terrestrial isopods crustaceans recorded in Auvergne region. This list is based on data from the literature and also from field surveys, detailed in this work. Surveys have targeted a sample of diverse habitats (grasslands and woodlands from medium altitude, limestone hills, caves, wetlands, gardens…). Twelve taxa are reported for the first time from Auvergne, enlarging known range for some species. This is particularly the case with Hyloniscus riparius and Tiroloscia pyrenaica, the latter being considered as endemic to the Pyrénées before. The authors update their distribution in France and set out the identifying characteristics of Tiroloscia pyreanaica.
La géologie des environs de Clermont-Ferrand / Geology of Clermont-Ferrand area

Published: January 2025

The geological history of Clermont area is the consequence of two major orogenic events : 1) the varician orogeny during Paleozoic, forming metamorphic and plutonic rocks. 2) the alpine subduction during Cenozoïc explains the subsidence of Limagne graben filled with oligocene sediments, the various volcanic activities and the late ascent and erosion of Massif central. All contribute to the formation of geological features which constitute microenvironments and reservoirs for local biodiversity.
Le Climat de la communauté de communes clermontoise / The climate around Clermont-Ferrand: a land of contrasts
Authors: Jolibert Nathalie
Published: January 2025

Une terre de contraste. La communauté de communes clermontoise est au croisement de différents types de climat. Les monts Dômes sont sous l’influence océanique avec de fortes et régulières précipitations tout au long de l’année (1042 mm à Orcines) tandis que la Limagne est sous influence continentale avec les précipitations les plus fortes en fin de printemps et été. La Limagne est une région sèche soumise à l’effet de Foëhn (600 mm/an). Les températures sont gouvernées par le relief avec une décroissance de 0.6°C par 100 m. Les températures moyennes sont de l’ordre de 11°C à Clermont-Fd et de 8°C à Orcines. De même manière, le vent dépend du relief. En Limagne, les directions sont à l’image de la vallée avec une prédominance des vents de nord et de sud tandis qu’à Orcines, le vent dépend de la circulation générale de l’atmosphère avec des vents d’ouest à sud-ouest dominants. Le soleil brille environ 1900 heures par an.

Published: January 2025

There is a remarkable diversity of natural environment in the Clermont-Ferrand area, thanks to the altitudinal gradient, the geological diversity, the topography etc. Previous studies in this region reported the distribution of priority habitats in the territory, and allowed us to select sites for the implementation of a long term monitoring of flora and vegetation. Nine sites were selected, each with their particularities, on which different methodologies were applied, like permanent sample plots or PhytoSocio-Ecological Toposequence (PSET) We report here the initial status of the monitoring, the exact location of the sample plots and the first phytoecological analysis of the studied environments.
Cartographie dynamique des habitats et des complexes d’habitats dans la région clermontoise / Vegetation dynamics and habitats mapping around Clermont-Ferrand
Authors: Roux Camille
Published: January 2025

Under the program CarHAB the French Ministry of Ecology Sustainable Development and Energy, trusted to Clermont University and IBHUC a study to propose a typology and methodology according dynamic catenal and landscape phytosociology approach. Clermont community’s territory was retained as a studied area because it consists of a very big variety of habitats. Five major types of systems were studied : an alluvial valley, xerothermic hills, tabelland and fault on crystalline rocks and mountain range of monts Dômes. A referential system and a catalog of plant associations of the studied area were set up to facilitate the phytosociological diagnosis, with the aim of determining the series and geoseries of vegetations. It emerges from this study that certain forest zones (channel of volcanic hills, plateau, breasts) were little studied by a phytosociologique point of view. Because of the artificialisation and of the anthropological effects, we also notice a disappearance of mature forests for the benefit of pioneers or post-pioneers woods. The first results show the diversity of the series of vegetation on the territory, a temporary map of the series and geoseries is proposed at the end of article.

La Roche Mandrin est un éperon granitique dominant la vallée de la Burande à proximité de Singles et de Larodde (Puy-de-Dôme). Elle est située le long d’une faille majeure du Massif central, le Sillon houiller. Compte-tenu de sa morphologie et de sa localisation sur le territoire d’anciennes baronnies, ainsi que de la présence sur son sommet de traces de constructions d’âge inconnu, elle est à l’origine de la légende de son occupation par le célèbre bandit Louis Mandrin (1725-1755). Cette courte note livre une description de cet affleurement rocheux en le replaçant dans son contexte géologique, et propose des éléments de description historiques.
L’existence de rythmes lunaires dans la vie des arbres a-t-elle été démontrée ? / Has influence of lunar rythms on the life of trees been proved ?
Authors: Baillaud Lucien
Published: January 2025

The diameter of tree-trunks oscillate during the succession of days and nights. Scientists have shown that during constant darkness it can happen two oscillations by a day. This result is questioned ; it has been credited with a sort of a tidal effect. It is hoped the experiments be done again by other scientists. Another research looks at the lunar dates of felling trees. In my opinion, in both cases, no lunar correlation has been really proved.

A propos de la première identification mondiale d'une excursion géomagnétique: Laschamp ou Laschamps ? / On the first ever identification of a geomagnetic excursion: Laschamp or Laschamps ?
Authors: Kornprobst Jacques
Published: January 2025

Cartographic records from the 18th, 19th and 20th centuries incorrectly transcribed the name of the village of Laschamps in the Puy-de-Dôme district (France) ; deprived of its final s, this name was generally written Laschamp. It is a betrayal of the medieval Occitan legacy from which the name is derived and it goes against the current inhabitants' spelling. Known worldwide since the discovery of the first geomagnetic excursion in 1967, it is unfortunate that this village is famous under an altered name.
Formas escolares: um olhar geográfico sobre a educação escolar

Published: January 2025

Estudar o processo da História da educação envolve uma série de fatores que perpetuam no ensino, principalmente na forma escolar que movimenta seus ideais, crenças, hábitos desde o seu objetivo de criação. A construção desse conceito causa uma reflexão sobre as práticas, modelos de ensino nas instituições escolares, papel da escola nesse contexto vista como um espaço de transmitir conhecimento e educar. Ademais, esse espaço específico é organizado através de uma infraestrutura, localizado em um lugar pela sociedade, visto como um espaço “isolado” desse social, na qual sofre imposições políticas configurando-se em uma forma escolar que está impregnada e reproduzimos atualmente. Utilizando metodologias de análise artigos e livros também como fontes de referências bibliográficas, o presente artigo tem como objetivo compreender e analisar as formas escolares buscando entender sobre uma perspectiva de um olhar geográfico a construção do espaço geográfico e a sua configuração atualmente considerando os temas acima expostos.
Eficácia da toxina botulínica no alívio dos sintomas da doença de Parkinson: uma revisão sistemática
Authors: Costa Mariane Brenda , Gasparin Caroline Cardozo , Santos Andressa Flores
Published: January 2025

A Doença de Parkinson (DP) é uma condição neurodegenerativa progressiva marcada pela perda de neurônios dopaminérgicos, resultando em sintomas motores como tremores, rigidez e bradicinesia, além de sintomas não-motores como distúrbios do sono e depressão. O tratamento inclui abordagens farmacológicas, como a levodopa e outros medicamentos que aumentam os níveis de dopamina, e intervenções não-farmacológicas, como exercício físico e fisioterapia. A importância da toxina botulínica na DP reside na sua capacidade de proporcionar alívio sintomático significativo com mínimos efeitos colaterais, melhorando a qualidade de vida dos pacientes. A aplicação precisa da TB A em músculos específicos pode ajudar a reduzir os sintomas motores incapacitantes e tratar problemas não-motores, oferecendo uma abordagem terapêutica complementar e muitas vezes essencial no manejo global da Doença de Parkinson.

Published: January 2025

Este estudo revisa as estratégias de diagnóstico e manejo terapêutico da candidíase oral em pacientes imunocomprometidos, com foco nos fatores predisponentes, como HIV, quimioterapia e diabetes mellitus. A candidíase oral é uma infecção fúngica frequentemente observada em indivíduos com sistemas imunológicos comprometidos, sendo Candida albicans a principal responsável pela infecção. Embora presente na microbiota oral de indivíduos saudáveis, a proliferação excessiva desse fungo ocorre em condições de desequilíbrio imunológico, resultando em infecção. O objetivo desta pesquisa é examinar as abordagens mais recentes para o diagnóstico e tratamento da candidíase oral em pacientes imunocomprometidos, explorando a relação entre a infecção e as complicações sistêmicas, como a candidemia. A metodologia consistiu em uma revisão de literatura descritiva, com análise de artigos publicados entre 2004 e 2024 nas bases PubMed, SciELO, LILACS e Google Scholar, incluindo estudos sobre prevalência, fatores de risco, diagnóstico e opções terapêuticas. Os resultados indicam que a candidíase oral é uma das infecções mais comuns entre pacientes imunossuprimidos, especialmente aqueles com HIV/AIDS. Os tratamentos mais frequentes envolvem antifúngicos tópicos como fluconazol e nistatina, embora o aumento da resistência antifúngica seja uma preocupação crescente. Alternativas terapêuticas, como fototerapia antimicrobiana, têm mostrado eficácia, mas necessitam de mais evidências. O diagnóstico precoce e o controle das condições predisponentes são cruciais para o manejo eficaz da infecção.

O ambiente universitário para os estudantes de medicina se torna, muitas vezes, propício ao desenvolvimento de quadros de depressão e ansiedade, o que pode resultar na redução do desempenho acadêmico, além do consequente descuido com a própria saúde. Desse modo, objetiva-se abordar a relação entre a graduação no curso medicina e o aparecimento de transtornos psiquiátricos, especificamente a ansiedade e a depressão, juntamente com a análise de um possível agrave de tal situação após os anos de 2020, pós-pandemia. Com isso, o presente estudo buscou avaliar artigos que tratassem sobre a temática ao longo do período de 2018 a 2023. Dessa forma, nota-se que os discentes do curso de medicina enfrentam demandas acadêmicas intensas e estressante ao longo da trajetória acadêmica, de modo mais intenso após o período da pandemia devido dificuldade de adaptação, o que implica em níveis elevados de ansiedade e depressão. Tal rotina desgastante com a universidade pode prejudicar o cotidiano do estudante dentro e fora desse ambiente. Com isso as instituições de ensino devem priorizar estratégias para garantia de suporte psicológico, como espaços de diálogo, contínuo que auxiliem diminuir o estresse psicológico.

Considerando que a poliomielite representa uma grave ameaça à saúde pública e que a cobertura vacinal no Brasil tem enfrentado desafios significativos, este estudo tem como objetivo analisar a evolução da vacinação contra a poliomielite nas diferentes regiões do país entre 2012 e 2022. Para isso, foi conduzido um estudo observacional, descritivo e transversal, com a coleta de dados do Sistema de Informação do Programa Nacional de Imunizações (SIPNI). Os resultados mostram uma queda alarmante na cobertura vacinal, especialmente entre 2020 e 2021, quando a taxa caiu para 71,04%, com a região Norte apresentando a menor cobertura, apenas 62,29%. Essa diminuição pode ser atribuída a diversos fatores, como a reorientação dos serviços de saúde em resposta à pandemia de COVID-19, bem como à insegurança econômica e à hesitação vacinal exacerbada pela desinformação nas redes sociais. Além disso, o recente ressurgimento de casos de poliomielite em países como Estados Unidos e Peru destaca a urgência de manter altas taxas de vacinação. Concluímos que é imperativo reforçar as campanhas de vacinação e implementar estratégias educativas que promovam a conscientização da população. A vigilância epidemiológica contínua e o engajamento da comunidade são essenciais para preservar os avanços na erradicação da poliomielite no Brasil e garantir a proteção da saúde infantil.

Depressão representa um importante problema de saúde, pois pode trazer incapacitação. Sua fisiopatologia não é totalmente esclarecida e seu diagnóstico é feito com base nos sintomas persistentes por mais de duas semanas. A vitamina B12 representa um grupo de micronutrientes chamados de cobalaminas e é encontrada exclusivamente em alimentos de origem animal. Tal vitamina tem importante papel na homeostase, participando desde a multiplicação celular (síntese de DNA) a processos de regulação do sistema nervoso central, como o bom funcionamento dos neurotransmissores e mielinização dos neurônios. Sua deficiência se dá principalmente pela má absorção entérica, podendo levar a quadros de anemia, neuropatia, fadiga e declínio cognitivo. A associação deficiência de vitamina B12 e depressão ainda não foi totalmente estabelecida, havendo discordância na literatura. Este estudo teve o intuito de comparar diferentes grupos de participantes que dosaram vitamina B12 e a relação com o uso de antidepressivo, visando estabelecer uma possível relação entre a deficiência de vitamina B12 e a presença de depressão. Para tanto, foram utilizados dados fornecidos por um laboratório de análises clínicas situado no interior do estado de São Paulo. A prevalência encontrada entre aqueles que apresentaram deficiência de vitamina B12, resultado normal ou acima do valor de referência parece não indicar uma relação entre deficiência de cobalamina e uso de antidepressivos. São necessários, portanto, mais estudos para elucidar esse tema ainda obscuro.

Published: January 2025

A perda progressiva de unidades dentarias comumente associada a doenças periodontais, extrações traumáticas, cistos, tumores e até mesmo trauma facial, ocasiona reabsorção óssea nos rebordos alveolares. Na região da maxila, esta gera uma atrofia óssea e pneumatização do seio maxilar, que como consequência, dificulta a reabilitação oral com a instalação de implantes dentários convencionais. Devido aos avanços tecnológicos e científicos, os implantes zigomáticos surgiram como uma boa alternativa na reabilitação em maxilas atróficas, reproduzindo maior previsibilidade e segurança. O objetivo deste artigo é relatar o caso de uma paciente de 80 anos de idade, sexo feminino, edentula total em ambas arcadas, sem uso de próteses dentaria há mais de 40 anos e com maxilas atróficas, com queixa de estar incomodada com a estética e função mastigatória, que compareceu na consulta privada para tratamento. Realizou-se um exame físico e avaliação tomográfica minuciosa, para o planejamento e intervenção cirúrgica de instalação de implantes zigomáticos duplos, para posterior reabilitação oral do paciente. O estudo reforça que a instalação de implantes zigomáticos é uma alternativa segura, e de boa aceitação para o tratamento reabilitador de pacientes com maxilas atróficas.

O trabalho explora a importância do Método Clínico Centrado na Pessoa (MCCP) na adesão ao tratamento do transtorno de ansiedade (TA), justificando-se pela alta prevalência desse transtorno no Brasil, que atinge 9,3% da população, e pela necessidade de abordagens que integrem fatores biopsicossociais no atendimento. O objetivo central é investigar como o MCCP pode influenciar positivamente a adesão dos pacientes ao tratamento, promovendo uma relação médico-paciente mais humanizada e colaborativa. Com base em uma revisão bibliográfica, destacam-se evidências de que o MCCP, ao favorecer a criação de vínculos e proporcionar ao paciente uma participação ativa em seu tratamento, aumenta a segurança e o conforto em seguir o plano terapêutico. Observa-se que a comunicação efetiva e a escuta ativa, aspectos essenciais do MCCP, contribuem diretamente para a satisfação do paciente e para o sucesso terapêutico. Conclui-se, assim, que a adoção do MCCP pode ser uma estratégia eficaz para melhorar a adesão ao tratamento do TA, promovendo uma abordagem integral que leva em conta as necessidades emocionais e sociais do paciente, reforçando, portanto, a eficácia terapêutica e o bem-estar.

Published: January 2025

Gallstone disease (GD) poses a substantial health challenge worldwide, and its complications are often associated with disturbances in the gut microbiota. The essential receptor through which the innate immune system detects bacterial components and controls inflammation, namely, nucleotide-binding oligomerization domain-containing protein 1 (
NOD1
), is a major participant in the interaction. This article examines the role of
NOD1
in GD, focusing on how gallstone-induced changes in the gut microbiota composition activate
NOD1
. Such activation initiates signaling pathways that lead to gut dysbiosis, further exacerbating GD. We investigate potential therapeutic targets within the
NOD1
signaling pathway and its interactions with other host factors, suggesting methods to restore imbalances in the gut microbiota and improve GD management. The clinical significance of these findings and future research directions are also discussed, highlighting the importance of comprehensive approaches to treat GD by targeting
NOD1
activity and the gut microbiota.

Developing advanced tissue-engineered membranes with biocompatibility, suitable mechanical qualities, and anti-fibrotic and anti-inflammatory actions is important for tympanic membrane (TM) repair. Here, we present a novel acoustically transmitted decellularized fish swim bladder (DFB) loaded with mesenchymal stem cells (DFB@MSCs) for TM perforation (TMP) repair. The DFB scaffolds are obtained by removing the cellular components from the original FB, which retains the collagen composition that favors cell proliferation. Benefitting from their spatially porous structures and excellent mechanical properties, the DFB scaffolds can provide a suitable microenvironment and mechanical support for cell growth and tissue regeneration. In addition, by loading mesenchymal stem cells on the DFB scaffolds, the resultant DFB@MSCs system exhibits remarkable anti-fibrotic and anti-inflammatory effects, together with the ability to promote cell migration and angiogenesis. In vivo experiments confirm that the prepared DFB@MSCs scaffolds can not only alleviate inflammatory response caused by TMP but also promote new vessel formation, TM repair, and hearing improvement. These features indicate that our proposed DFB@MSCs stent is a prospective tool for the clinical repair of TM.

Рассмотрена процедура расчета амплитуды и фазы сигналов в элементах антенной решетки для синтеза требуемой формы диаграммы направленности источника излучения и оптимизации условий приема/передачи радиосигналов с использованием нейрокомпьютерных процедур. Предложен нейросетевой подход к непрерывному контролю формы диаграммы направленности источника излучения. Описанная процедура призвана повысить вероятность приема полезных радиосигналов в условиях помех, вызванных многолучевостью, и эффективность цифровых систем и сетей связи в целом.

The procedure for calculating the amplitude and phase of signals in the antenna array elements for synthesizing the required shape of the radiation source radiation pattern and optimizing the conditions for receiving/ transmitting radio signals using neurocomputer procedures is considered. A neural network approach to the continuous control of the shape of the radiation source radiation pattern is proposed. The described procedure, as the authors believe, will increase the likelihood of receiving useful radio signals in conditions of interference caused by multipath and increase the efficiency of digital systems and communication networks in general.
