Top 100 most cited papers on diagnostic aids for oral cancer: A bibliometric analysis.

BACKGROUND: Oral cancer (OC) is a multifactorial disease that affects the oral cavity. The mortality rate is approximately 50 % and a high percentage of patients are diagnosed in advanced stages. Early diagnosis has been well demonstrated to improve overall survival, mainly when detected at a localized stage. Non-invasive techniques can help identify malignant features in real time, thus improving the path to diagnosis. This study aimed to perform a bibliometric analysis of the top 100 articles cited on diagnostic aids for oral cancer. METHODS: Articles from 2000 to 2023 in Scopus were scanned using five OC topic titles crossed with 27 diagnostic aid keywords. Duplicate manuscripts were eliminated using Microsoft Excel software and publications were ranked according to their citation count. This study selected and analyzed the top 100 most cited English-language papers. RESULTS: 86,676 citations were accumulated by the top 100 articles most cited. 2011 was the year with the highest number of publications with OC papers. The article with the most citations obtained a total of 30,832. The United States was the country with the most publications, with a total of 45, and UCLA was the institution with the most publications (7) among the top 100 most cited papers. CONCLUSIONS: This study identified the top 100 most cited articles on diagnostic aids for oral cancer. These results can help dentists, specialists, healthcare providers, and researchers become familiar with the most influential publications in this field.

Water discharge variations control fluvial stratigraphic architecture in the Middle Eocene Escanilla formation, Spain.

Ancient fluvial deposits typically display repetitive changes in their depositional architecture such as alternating intervals of coarse-grained highly amalgamated (HA), laterally-stacked, channel bodies, and finer-grained less amalgamated (LA), vertically-stacked, channels encased in floodplain deposits. Such patterns are usually ascribed to slower, respectively higher, rates of base level rise (accommodation). However, "upstream" factors such as water discharge and sediment flux also play a potential role in determining stratigraphic architecture, yet this possibility has never been tested despite the recent advances in the field of palaeohydraulic reconstructions from fluvial accumulations. Here, we chronicle riverbed gradient evolution within three Middle Eocene (~ 40 Ma) fluvial HA-LA sequences in the Escanilla Formation in the south-Pyrenean foreland basin. This work documents, for the first time in a fossil fluvial system, how the ancient riverbed systematically evolved from lower slopes in coarser-grained HA intervals, and higher slopes in finer-grained LA intervals, suggesting that bed slope changes were determined primarily by climate-controlled water discharge variations rather than base level changes as often hypothesized. This highlights the important connection between climate and landscape evolution and has fundamental implications for our ability to reconstruct ancient hydroclimates from the interpretation of fluvial sedimentary sequences.

The Protective Role of Ozone Therapy in Kidney Disease: A Review.

Ozone (O3) is a reactive oxygen species (ROS) that can interact with cellular components and cause oxidative stress. Following said logic, if O3 induces such a stressful milieu, how does it exert antioxidant functions? This is mediated by controlled toxicity produced by low concentrations of O3, which enhance the cell's suppliance of antioxidant properties without causing any further damage. Therapeutic concentrations vary extensively, although 50 µg/mL is commonly used in experimental and clinical procedures, given that augmented concentrations might work as germicides or cause endogenous damage. O3 therapy has been shown to be effective when applied before or after traumatic renal procedures, whether caused by ischemia, xenobiotics, chronic damage, or other models. In this review, we focus on discussing the role of O3 therapy in different models of kidney damage associated with fibrosis, apoptosis, oxidative stress, and inflammation. We integrate and report knowledge about O3 in renal therapy, debunking skepticism towards unconventional medicine, explaining its proven therapeutic properties, and thus providing background for its use in further research as well as in clinical settings.

A 3D-Printed Large Holding Capacity Device for Minimum Volume Cooling Vitrification of Embryos in Prolific Livestock Species.

Although many devices have been developed to reduce sample volume, with an explosion of methods appearing in the literature over the last decade, commercially available devices with simultaneous vitrification of a larger number of embryos are scarce, with the apparent gap for their use in prolific livestock species. In this study, we investigated the effectiveness of a new three-dimensional (3D)-printed device that combines minimum volume cooling vitrification with simultaneous vitrification of a larger number of rabbit embryos. Late morulae/early blastocysts were vitrified with the open Cryoeyelet® device (n = 175; 25 embryos per device), the open Cryotop® device (n = 175; 10 embryos per device), and the traditional closed French mini-straw device (n = 125; 25 embryos per straw) and compared in terms of in vitro development and reproductive performance after transfer to adoptive mothers. Fresh embryos constituted the control group (n = 125). In experiment 1, there was no difference in the development rate to the blastocyst hatching stage between the CryoEyelet® and the other devices. In experiment 2, the CryoEyelet® device showed a higher implantation rate compared with the Cryotop® (6.3% unit of SD, p = 0.87) and French mini-straw® (16.8% unit of SD, p = 1.00) devices. In terms of offspring rate, the CryoEyelet® device was similar to the Cryotop® device but superior to the French straw device. Regarding embryonic and fetal losses, the CryoEyelet® showed lower embryonic losses compared to other vitrification devices. The analysis of bodyweight showed that all devices showed a similar outcomes-a higher birthweight but a lower body weight at puberty than those in the fresh transfer embryos group. In summary, the CryoEyelet® device can be used for the vitrification of many late morulae or early blastocyst stage rabbit embryos per device. Further studies should be performed to evaluate the CryoEyelet® device in other polytocous species for the simultaneous vitrification of a large number of embryos.

Physical and geochemical characteristics of land mud volcanoes along Colombia's Caribbean coast and their societal impacts.

The Caribbean coast is characterized by the presence of mud volcanoes, a secondary phenomenon of volcanism similar to mud diapirs for its development and evolution, but different in terms of geological features and forms. These mud volcanoes are often located close to tectonic faults and oil and gas deposits. Their geological context is dominated by the presence of clay sediments and brackish water, that favors the decomposition of organic material and the formation of methane. Mud volcanoes can thus be an important reservoir of hydrocarbons. This paper aims to fill the existing gap in the knowledge of mud volcanoes (MVs) of Colombia. We analyze the physical and geochemical characteristics of nine onshore mud volcanoes located in the Departments of Atlántico (La Laguna), Bolívar (Las Palomas, La Bonga, Santa Catalina, Yerbabuena, Clemencia, and Membrillal), Cordóba (Los Olivos), and Magdalena (Cañaveral). These structures present a kaolinitic composition, except for La Laguna mud volcano in which smectite is predominant. Apart from tectonic processes, this influences the shape and size of MVs and, also, the type and frequency of eruptions. The abundance of methane in all sites confirms the thermogenic origin of these structures. MVs are often considered landscape attractions as well as a therapeutic resources, but unfortunately they also represent a serious risk for the local communities, due to the frequent unexpected, eruptions, sometimes accompanied by the release of toxic gases or by landslides, that can damage the infrastructures and hurt the population living in the area. The MVs are classified into five vulnerability classes using a novel synthetic index which could improve the understanding of risks associated with the presence of MVs in proximity to towns and infrastructures.

Endometrial autotransplantation in rabbits: Potential for fertility restoration in severe Asherman's syndrome.

OBJECTIVE: Uterine transplantation is now considered a feasible treatment for women with absolute uterine factor infertility and has been successfully performed for a woman with Asherman's syndrome (AS). The endometrium is a clinically and histologically distinct entity from the surrounding myometrium. Endometrial transplantation (ETx) may offer a less invasive option, with less immunogenic impact, to restore fertility in women with severe AS. The objective of this study was to assess the feasibility of ETx by evaluating surgical and reproductive outcomes following endometrial autotransplantation in a rabbit model. STUDY DESIGN: A longitudinal study assessing surgical, biochemical, radiological, reproductive and histological outcomes following endometrial autotransplantation in ten New Zealand white rabbits. RESULTS: Ten procedures were performed, including 8 endometrial auto-transplants (ETx) and 2 endometrial resections (ER), to control against endometrial regeneration. Eight procedures were successful, whereas two rabbits from the ETx group died intra-operatively. Three rabbits were euthanised at 48, 72 and 96 h post-operatively to assess gross and histological appearances. Two rabbits, one from the ETx group and one from the ER group, died four weeks and eight weeks post-operatively. Three rabbits subsequently underwent two cycles of in-vitro fertilization. The first cycle resulted in an implantation rate of 57% in the un-operated uteri. In two rabbits who underwent ETx, an implantation rate of 28.6% was seen. In the second cycle, an implantation rate of 61.9 % (13 implantations) was observed in the control uteri. In the two ETx females, an implantation rate of 14.3 % was seen. No pregnancies were seen in either cycle in the animals who underwent ER. Despite successful implantations in both cycles in the ETx rabbits, no livebirths were achieved. Following death or euthanasia there was gross and microscopic evidence of viable endometrium following ETx, but not following ER. CONCLUSION: This study has revealed, for the first time, the feasibility of ETx with gross and microscopic evidence of viable endometrium, and the demonstration of clinical pregnancies. Whilst further studies are essential, and the achievement of successful livebirths fundamental, ETx may offer a potential fertility restoring opportunity for women with severe, treatment refractory cases of AS.

Psychological Distress, Family Support and Employment Status in First-Year University Students in Spain.

Mental disorders are consistently and closely related to psychological distress. At the start of the university period, the relationship between a student's psychological distress, family support, and employment status is not well-known. The aims of this study were: To determine the prevalence of psychological distress in first-year university students and to analyze its relationship with family support and the student's employment status. Data from 4166 first-year university students from nine universities across Spain were considered. The prevalence of psychological distress was obtained using the GHQ-12, a valid and reliable screening tool to detect poor mental health. To analyze the relationship between psychological distress, family support, and employment status, logistic regression models were fitted. Regarding the prevalence found, 46.9% of men and 54.2% of women had psychological distress. In both genders, psychological distress levels increased as family support decreased. Among women, psychological distress was associated with their employment status. The prevalence of psychological distress among first-year university students in Spain is high. In addition, family support, and employment status for women, could be factors to take into account when developing psychological distress prevention strategies at the beginning of the university period.

Drug use, family support and related factors in university students. A cross-sectional study based on the uniHcos Project data / Consumo de drogas ilegales, apoyo familiar y factores relacionados en estudiantes universitarios. Un estudio transversal basado en datos del Proyecto uniHcos

Objective: To assess the prevalence of illegal drug use in college students on any previous occasion, during the previous year and the previous month, and to analyze the relationship between illegal drug use and family support and other factors. Methods: A cross-sectional study using data from students participating in the uniHcos project (n = 3767) was conducted. The prevalence and age of onset of consumption of cannabis, non-prescription sedatives, stimulants and depressants was evaluated. Polyconsumption was also assessed. The independent variables were: family support, age, residence, and employment status. To determine the factors related to drug use multivariate logistic regression models stratified by gender were fitted. Results: Differences between men and women in prevalence of illegal drug use except non-prescription sedatives were observed. In both genders, less family support was associated with higher consumption of all drugs, except depressants, and with polyconsumption. To be studying and looking for work was related to cannabis and stimulant use and to polyconsumption among women, but only to cannabis use among men. Conclusions: These results support the notion that the start of university studies is a particularly relevant stage in the onset of illegal drug use and its prevention, and that consumption may be especially associated with family support

Objetivo: Evaluar la prevalencia del consumo de drogas ilegales en estudiantes universitarios y analizar la relación entre dicho consumo, el apoyo familiar y otros factores. Método: Se realizó un diseño transversal basado en datos de participantes en el proyecto uniHcos (n = 3767). Se evaluaron la prevalencia y la edad de inicio del consumo de cannabis, tranquilizantes sin receta, estimulantes y depresores, y el policonsumo. Como variables independientes se consideraron el apoyo familiar, la edad, la residencia y la situación laboral. Para la determinación de los factores asociados al consumo de drogas se ajustaron modelos de regresión logística estratificados por sexo. Resultados: Se observaron diferencias entre hombres y mujeres en la prevalencia del consumo de todas las drogas ilegales, excepto tranquilizantes sin receta. En ambos sexos, cuanto peor apoyo familiar, mayor consumo de todas las drogas, excepto depresores y policonsumo. Encontrarse estudiando y buscando trabajo se relacionó con el consumo de cannabis, estimulantes y policonsumo en las mujeres, y solo con cannabis en los hombres. Conclusiones: Los resultados de este estudio aportan nueva evidencia a favor de que el inicio de la etapa universitaria es un momento de especial relevancia en el inicio del consumo de drogas ilegales y su prevención, pudiendo este consumo estar especialmente relacionado con el apoyo familiar

[Epidemiology of human immunodeficiency virus (HIV) infection in the province of Salamanca (1985-2002)]. / Epidemiología de la infección por virus de la inmunodeficiencia humana (VIH) en la provincia de Salamanca (1985-2002).

INTRODUCTION: Since effective treatment against HIV has become available, HIV infection surveillance is focussed not only on AIDS cases, but also on new cases of HIV infection. One of the methods used for this task is compilation of case records. We report the results of 18 years of recording information on new diagnoses of HIV (1985-2002) in the area of Salamanca (Spain). METHODS: Our report system is based on active monitoring of results from the microbiology laboratory of the Salamanca Health Area. All patients testing positive in HIV analytical studies and who had not been previously diagnosed as HIV-infected are included in the report system. RESULTS: A total of 188 579 analytical results were studied. We found 16,772 (9.23%) HIV-positive results, 1984 of which were new HIV infection diagnoses. The incidence for the entire period was 556 cases/100,000 inhabitants. The highest incidence was found in 1992 (62.2 cases/100,000), with a progressive decrease thereafter to 2002 (5.18/100,000). Among the total, 75.3% of patients were men between 20 and 39 years old and more than half (62.2%) were intravenous drug users. Over the period studied, there has been an increase in the age of patients at the time of diagnosis, a trend to increases in the number of cases acquired through heterosexual transmission and a reduction in the number of drug users. During the study period, 312 AIDS cases were declared. CONCLUSIONS: Epidemiological information systems for HIV surveillance are essential to know the features, magnitude and evolution of the epidemic. Creation of a national HIV infection surveillance system to compile the information from smaller regional or local organisms would contribute substantially to our understanding of the epidemiology and evolution of HIV infection.
