    Authors presented the case of a 4-year-old male patient who suffered a dog bite on his face with partial amputation of the nasal tip, managed at another institution conservatively, so that one year after the injury he came for the nasal deformity. A frontal flap was performed for reconstruction achieving excellent results, coverage was achieved with similar characteristics of the skin as color and texture. The patient had a follow-up of 5 years with an appropriate course. Authors presented the case due to few reports in the literature of its use in children, where it can be observed that it is an excellent reconstructive tool

    Background: Dog bites continue to be a frequent cause for plastic and reconstructive services in the world. The grand majority of these cases affect the head and neck area; and more often than not they involve the commissure and the lips. The latter leading to an increased level of difficulty and a substantial decrease on the posibilities for a successful reconstruction. This case report focuses on the exploration of the Abbe-Estlander flap as an efficient alternative in most of these cases.Methods: We present two clinical cases involving dog bites where the affected area of both patients was estimated to be one third of the total volume of the lip. Both patients required emergency reconstructive surgery. An Estlander flap was successfully performed in both instances. The purpose of the article is to share the results and motivate the medical community to continue to use this method as a strong avenue for an effective recovery.Results: After two months of the surgery, the team followed up with both patients and they were satisfied with the results. Patient A presented adequate healing of the wound; a lack of alignment of the mucocutaneous rim and rounding of the commissure was observed. Phonation, oral continence without any leakage and complete closure of the lip were also part of the recovery assessment. Patient B presented adequate healing of the wound, phonation and medium oral continence with occasional leakage of liquids and incomplete closure.Conclusions: The Abbe-Estlander flap is still an excellent reconstructive alternative for upper and lower lip reconstruction where the affected area is up to one third of the total volume. As long as the commissure involvement represents minimum difficulty, both aesthetic and functional objectives can be successfully attained using this flap

    The health risk of triatomines as vectors of Trypanosoma cruzi is related to the domiciliation of originally wild species that manage to adapt to human habitats, finding varied sources of food and shelter. Residual fumigation with pyrethroid insecticides is used to control these insects, but due to the resistance of triatomines to chemical insecticides and high costs of permanent fumigation, the potential of some entomopathogenic fungi as biological controllers has been successfully tested. However, the effect of sub-lethal doses on reproductive parameters is unknown, as these factors are very important in population growth and colonization of new habitats. In this work we tested the effect of a low concentration of Beauveria conidia. bassiana (1 x 10⁸ conidia/ml) on the reproductive parameters of Meccus pallipennis females inoculated in the adult stage, counting daily the number of eggs laid and hatched in a period of 44 days. No inhibition of oviposition was recorded, all the females laid eggs, but the fungal infection reduced the fertility of the treated females by 63%. The reproductive yield of the control females was 56.7 ± 3.8 eggs/female/life while the yield of the infected females was 20.8 ± 2.9 eggs/female/life, finding significant differences between the means of the groups. (p<0.0008). No significant differences were detected in the hatching percentage between both groups (p=.3737). The reproductive system of the infected females did not present variation in the size of the structures, however, organisms without terminal filament, germium, and empty ovarioles were observed, with some oocytes detached from the yolk. We confirmed the presence of B. bassiana in genitalia and oocytes. During the experimental design it was observed that the males treated with B. bassiana did not complete the mating pattern.El riesgo sanitario de los triatominos como vectores de Trypanosoma cruzi está relacionado con la domiciliación de especies originalmente selváticas que logran adaptarse a hábitats humanos, encontrando variadas fuentes de alimento y refugio. Para el control de estos insectos se utiliza la fumigación residual con insecticidas piretroides, pero debido a la resistencia de los triatominos a insecticidas químicos y altos costos de fumigaciones permanentes, alternativamente se ha probado con éxito el potencial de algunos hongos entomopatógenos como controladores biológicos. Sin embargo, se desconoce el efecto de dosis sub letales sobre parámetros reproductivos, siendo estos factores muy importantes en el crecimiento poblacional y colonización de nuevos hábitats. En este trabajo probamos el efecto de una concentración de conidios baja de Beauveria. bassiana (1 x 10⁸ conidios/ml) en los parámetros reproductivos de hembras de Meccus pallipennis inoculadas en el estadio adulto, contabilizando diariamente el número de huevos puestos y eclosionados en un periodo de 44 días. No se registró inhibición de la oviposición, todas las hembras pusieron huevos, pero la infección fúngica redujo un 63% la fertilidad de las hembras tratadas. El rendimiento reproductivo de las hembras control fue de 56.7 ± 3.8 huevos /hembra/vida mientras que el rendimiento de las hembras infectadas fue de 20.8 ± 2.9 huevos /hembra/vida encontrando diferencias significativas entre las medias de los grupos. (p<0.0008). No se detectaron diferencias significativas en el porcentaje de eclosión entre ambos grupos (p=.3737). El sistema reproductor de las hembras infectadas no presento variación en el tamaño de las estructuras, sin embargo, se observaron organismos sin filamento terminal, germario, y las ovariolas vacías, con algunos ovocitos desprendidos del vitelario. Confirmamos la presencia de B. bassiana en la genitalia y ovocitos. Durante el diseño experimental se observó que los machos tratados con B. bassiana no completaron el patrón de cópula

    Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is the causal agent of Coronavirus disease 2019 (COVID-19), a pandemic disease declared in 2020. The clinical manifestations of this pathology are heterogeneous including fever, cough, dyspnea, anosmia, headache, fatigue, taste dysfunction, among others. Survivors of COVID-19 have demonstrated several persistent symptoms derived from its multisystemic physiopathology. These symptoms can be fatigue, dyspnea, chest pain, dry and productive cough, respiratory insufficiency, and psychoemotional disturbance. To reduce and recover from the post-COVID-19 sequelae is fundamental an early and multifactorial medical treatment. Integral post-COVID-19 physiotherapy is a tool to reduce dyspnea, improve lung capacity, decrease psychoemotional alterations, as well as increase the muscle strength affected by this disease. Thus, the aim of this study was to establish a novel physiotherapeutic plan for post-COVID-19 patients, evaluating the effect of this treatment in the reduction of the sequelae in terms of lung capacity, cardio-respiratory, and muscular strength improvements. This was a cross-sectional study in which a protocol of 12 sessions in 4 weeks of physiotherapy was implemented in the patients enrolled. We conducted a medical assessment, an interview, a DASS-21 test, a spirometry, a 6-min walk test, and a hand dynamometer test to evaluate the post-COVID condition of patients before and after the sessions. A total of 42 patients participated in the program. Results of this work showed a decrease of around 50% of post-COVID-19 sequelae and an improvement in the psychoemotional status of patients. Also, we observed an increase of 7.16% in the FEV1 value and 7.56% for FVC. In addition, the maximal functional capacity increased by 0.577 METs, the 6-min walk test performance increased by 13%, and the SpO2 improved by 1.40%. Finally, the handgrip strength test showed an improvement in the left hand and right hand of 2.90 and 2.24 Kg, respectively. We developed this study to propose a novel methodology to provide information for a better treatment and management of post-COVID-19 patients

    Introduction: The COVID-19 pandemic has had a significant social and health impact. Given the high risk of contagion and the potential collapse of the healthcare system, strategies such as social isolation, the use of personal protective equipment, and an increased reliance on telemedicine were adopted. These measures altered the dynamics of end-of-life patient care. Methodology: This observational cross-sectional study explored the experiences of home care staff providing end-of-life care and the impact of the pandemic on the care process, as well as on their quality of life and emotional well-being. A survey incorporating the adapted Care Of the Dying Evaluation (iCODE) questionnaire was conducted, alongside an assessment of quality of life using question 30 of the EORTC QLQ, and emotional wellbeing using the PANAS scale. Results: The experiences of 131 deceased patients were characterized. Professionals reported adequate therapeutic efforts in managing pain, dyspnea, and delirium. Additionally, they noted that the pandemic impeded treatment in 24% of the patients. The average quality of life score for professionals was 6 points, with a predominantly positive affect reported. Conclusions: Healthcare professionals in home-based care programs observed that the pandemic affected the treatment of nearly a quarter of end-of-life patients. Nonetheless, they highlighted that satisfactory symptomatic care and control were maintained. Additionally, they reported an adequate quality of life

    Methionine Cycle Rewiring by Targeting miR-873-5p Modulates Ammonia Metabolism to Protect the Liver from Acetaminophen

    Drug-induced liver injury (DILI) development is commonly associated with acetaminophen (APAP) overdose, where glutathione scavenging leads to mitochondrial dysfunction and hepatocyte death. DILI is a severe disorder without effective late-stage treatment, since N-acetyl cysteine must be administered 8 h after overdose to be efficient. Ammonia homeostasis is altered during liver diseases and, during DILI, it is accompanied by decreased glycine N-methyltransferase (GNMT) expression and S-adenosylmethionine (AdoMet) levels that suggest a reduced methionine cycle. Anti-miR-873-5p treatment prevents cell death in primary hepatocytes and the appearance of necrotic areas in liver from APAP-administered mice. In our study, we demonstrate a GNMT and methionine cycle activity restoration by the anti-miR-873-5p that reduces mitochondrial dysfunction and oxidative stress. The lack of hyperammoniemia caused by the therapy results in a decreased urea cycle, enhancing the synthesis of polyamines from ornithine and AdoMet and thus impacting the observed recovery of mitochondria and hepatocyte proliferation for regeneration. In summary, anti-miR-873-5p appears to be an effective therapy against APAP-induced liver injury, where the restoration of GNMT and the methionine cycle may prevent mitochondrial dysfunction while activating hepatocyte proliferative response.We thank Ministerio de Ciencia e Innovación, Programa Retos-Colaboración RTC2019- 007125-1 (for J.S. and M.L.M.-C.); Instituto de Salud Carlos III: Proyectos de Investigación en Salud DTS20/00138 (for J.S. and M.L.M.-C.), PI20/00690 (for R.J.) and PT20/000127 (for M.I.L.); CIBERehd: EHD21TRF01/2022 (to M.L.M.-C.); Departamento de Industria del Gobierno Vasco (for M.L.M.-C.); Ministerio de Ciencia, Innovación y Universidades MICINN: PID2020-117116RB-I00 and RTI2018- 096759-1-100 integrado en el Plan Estatal de Investigación Cientifica y Técnica y Innovación, cofinanciado con Fondos FEDER (for M.L.M.-C. and T.C.D., respectively); BIOEF (Basque Foundation for Innovation and Health Research); Asociación Española contra el Cáncer (AECC) (to M.L.M.-C., T.C.D.); AECC: GCTRA18006CARR (to A.C.); Fundación Científica de la Asociación Española Contra el Cancer (AECC Scientific Foundation) Rare Tumor Calls 2017 (for M.L.M.); La Caixa Foundation Program (for M.L.M.); BFU2015-70067-REDC, BFU2016-77408-R and BES-2017-080435 (MINECO/FEDER, UE); Ministerio de Ciencia, Innovación y universidades PID2019-108787RB-100 (to A.C.), PID2019- 109055RB-I00 (L.A.M.-C.), PID2020-117941RB-100 (to F.J.C.); Spanish Ministry of Economy and Competitiveness Grants BFU2013-47531-R and BFU2016-77408-R (L.A.M.-C.) and the FIGHT-CNNM2 project from the EJP RD Joint Transnational Call (JTC2019) (Ref.

    Background: The contribution of the virus to the pathogenesis of severe COVID-19 is still unclear. We aimed to evaluate associations between viral RNA load in plasma and host response, complications, and deaths in critically ill patients with COVID-19. Methods: We did a prospective cohort study across 23 hospitals in Spain. We included patients aged 18 years or older with laboratory-confirmed SARS-CoV-2 infection who were admitted to an intensive care unit between March 16, 2020, and Feb 27, 2021. RNA of the SARS-CoV-2 nucleocapsid region 1 (N1) was quantified in plasma samples collected from patients in the first 48 h following admission, using digital PCR. Patients were grouped on the basis of N1 quantity: VIR-N1-Zero ([removed]2747 N1 copies per mL). The primary outcome was all-cause death within 90 days after admission. We evaluated odds ratios (ORs) for the primary outcome between groups using a logistic regression analysis. Findings: 1068 patients met the inclusion criteria, of whom 117 had insufficient plasma samples and 115 had key information missing. 836 patients were included in the analysis, of whom 403 (48%) were in the VIR-N1-Low group, 283 (34%) were in the VIR-N1-Storm group, and 150 (18%) were in the VIR-N1-Zero group. Overall, patients in the VIR-N1-Storm group had the most severe disease: 266 (94%) of 283 patients received invasive mechanical ventilation (IMV), 116 (41%) developed acute kidney injury, 180 (65%) had secondary infections, and 148 (52%) died within 90 days. Patients in the VIR-N1-Zero group had the least severe disease: 81 (54%) of 150 received IMV, 34 (23%) developed acute kidney injury, 47 (32%) had secondary infections, and 26 (17%) died within 90 days (OR for death 0·30, 95% CI 0·16–0·55; p<0·0001, compared with the VIR-N1-Storm group). 106 (26%) of 403 patients in the VIR-N1-Low group died within 90 days (OR for death 0·39, 95% CI 0·26–0·57; p[removed]11 página

    Biodiversity loss is one of the main challenges of our time,1,2 and attempts to address it require a clear un derstanding of how ecological communities respond to environmental change across time and space.3,4 While the increasing availability of global databases on ecological communities has advanced our knowledge of biodiversity sensitivity to environmental changes,5–7 vast areas of the tropics remain understudied.8–11 In the American tropics, Amazonia stands out as the world’s most diverse rainforest and the primary source of Neotropical biodiversity,12 but it remains among the least known forests in America and is often underrepre sented in biodiversity databases.13–15 To worsen this situation, human-induced modifications16,17 may elim inate pieces of the Amazon’s biodiversity puzzle before we can use them to understand how ecological com munities are responding. To increase generalization and applicability of biodiversity knowledge,18,19 it is thus crucial to reduce biases in ecological research, particularly in regions projected to face the most pronounced environmental changes. We integrate ecological community metadata of 7,694 sampling sites for multiple or ganism groups in a machine learning model framework to map the research probability across the Brazilian Amazonia, while identifying the region’s vulnerability to environmental change. 15%–18% of the most ne glected areas in ecological research are expected to experience severe climate or land use changes by 2050. This means that unless we take immediate action, we will not be able to establish their current status, much less monitor how it is changing and what is being lostinfo:eu-repo/semantics/publishedVersio
