Species Delimitation in a Polyploid Group of Iberian Jasione (Campanulaceae) Unveils Coherence between Cryptic Speciation and Biogeographical Regionalization.

Groups with morphological stasis are an interesting framework to address putative cryptic species that may be hidden behind traditional taxonomic treatments, particularly when distribution ranges suggest disjunct and environmentally heterogeneous biogeographic patterns. New hypotheses of delimitation of evolutionary independent units can lead to the identification of different biogeographic processes, laying the foundation to investigate their historical and ecological significance. Jasione is a plant genus with a distribution centered in the Mediterranean basin, characterized by significant morphological stasis. Within the western Mediterranean J. gr. crispa species complex, J. sessiliflora s.l. and allied taxa form a distinct group, occupying environmentally diverse regions. At least two ploidy levels, diploid and tetraploid, are known to occur in the group. The internal variability is assessed with phylogenetic tools, viz. GMYC and ASAP, for species delimitation. The results are compared with other lines of evidence, including morphology and cytology. The fitting of distribution patterns of the inferred entities to chorological subprovinces is also used as a biogeographical and environmental framework to test the species hypothesis. Despite the scarcity of diagnostic morphological characters in the group, phylogenetic delimitation supports the description of at least one cryptic species, a narrow endemic in the NE Iberian Peninsula. Moreover, the results support the segregation of a thermophilic group of populations in eastern Iberia from J. sessiliflora. Ploidy variation from a wide geographical survey supports the systematic rearrangement suggested by species delimitation. Taxonomic reorganization in J. sessiliflora s.l. would allow ecological interpretations of distribution patterns in great accordance with biogeographical regionalization at the subprovince level, supporting geobotanical boundaries as a framework to interpret species ecological coherence of cryptic lineages. These results suggest that species differentiation, together with geographic isolation and polyploidization, is associated with adaptation to different environments, shifting from more to less thermophilic conditions. Thus, the recognition of concealed evolutionary entities is essential to correctly interpret biogeographical patterns in regions with a complex geologic and evolutionary history, such as the Mediterranean basin, and biogeographical units emerge as biologically sound frameworks to test the species hypothesis.

High yield production of cyanidin-derived pyranoanthocyanins using 4-vinylphenol and 4-vinylguaiacol as cofactors.

Pyranoanthocyanins are anthocyanin-derived pigments with vivid colors and enhanced stability, making them promising food colorants. We evaluated two 4-vinylphenols, decarboxylated p-coumaric (pCA) and ferulic acid (FA), as cofactors for pyranoanthocyanin formation. Cyanidin-3-glycosides from saponified black carrot were incubated with 4-vinylphenol or 4-vinylguaiacol in different anthocyanin-to-cofactor molar ratios (1:1-1:30) to form pyranoanthocyanins. Formation efficiency (45 °C, ≤96 h) was compared to their respective precursors at a 1:30 ratio. Composition changes were monitored using uHPLC-PDA-ESI-MS/MS. Pyranoanthocyanin yields with 4-vinylphenol (13.8-33.4%) were ∼12× higher than with pCA and yields with 4-vinylguaiacol (8.1-31.0%) were ∼6.5× higher than with FA. Molar ratios of 1:5 and 1:10 yielded significantly more pyranoanthocyanins. Pyranoanthocyanin formation with 4-vinylphenols followed first-order kinetics, whereas formation with hydroxycinnamic acids followed zero-order kinetics. Detection of intermediate compounds was consistent with a nucleophilic addition and aromatization formation mechanism. Overall, pyranoanthocyanin formation with 4-vinylphenols was more efficient than with hydroxycinnamic acids.

Nomenclature and Typification of the Jasione L. (Campanulaceae) Groups from the Eastern Mediterranean Basin.

In this research, all the published names of Jasione (Campanulaceae) in the species, subspecies, and variety ranks for populations from the Balkan and Anatolian peninsulas are reviewed, including names of taxa allied to these groups in surrounding areas. These two areas are among the main centers of diversity of the genus, albeit no recent revisions to address the regional taxonomical complexity of the genus have been published for the Balkans and Anatolia. In this work, the taxonomic status and typification of twenty-six published names are discussed, including the plethora of names within the Jasione heldreichii, J. supina, and J. orbiculata taxonomic complexes. In total, eleven lectotypes and one neotype are designated for names from the aforementioned regions, plus one from southern Italy. This nomenclatural clarification establishes a reference for ongoing and future taxonomic and evolutionary studies of Jasione in the Mediterranean basin. In a genus prone to micro-endemism and cryptospeciation, a number of the historically described forms, despite being disregarded by current taxonomic treatments, may, therefore, deserve further attention.

Does price-cap regulation work for increasing access to contraceptives? Aggregate- and pharmacy-level evidence from Colombia.

Price caps through international reference pricing are widely used worldwide but not so commonly in over-the-counter markets. We study the short-term effects of a price cap regulation for oral contraceptives in Colombia, a market dominated by the presence of several branded generics with multiple active ingredients. Most of the regulated products were fourth-generation contraceptives, and the Colombian health benefits plan only covers second-generation ones, resulting in a de facto over-the-counter market. Our aim is to establish whether the regulation triggered a competitive response within and across product categories, by price levels and regulatory status. The panel data analysis of quarterly level data for 52 drugs (and 79 drugs in an expanded sample without transactions for some quarters) reveals a massive expansion of transactions, for the directly regulated products that were formerly the most expensive, and for the indirectly regulated (i.e., a regulated ingredient) among those with an intermediate price. Although this price reduction could have led to a crowd out of the publicly provided contraceptives, we show that this is not the case. Since the information system cannot trace the final consumers' purchases, we complement our analysis with an audit study involving 213 pharmacies in Bogota. We find that the price reduction was effectively transmitted to the final consumers.

Diagnostic approach to Aicardi syndrome: A case report.

Aicardi syndrome is an X-linked-dominant genetic condition that is present almost exclusively in females. To diagnose Aicardi syndrome, the classic triad of agenesis of the corpus callosum, infantile spasms, and chorioretinal lacunae must be present. Here, we described a case of a female newborn baby delivered at 36 weeks of gestation that arrived at the emergency department with stiffening of arms and legs; therefore, an electroencephalogram was performed, showing generalized polypots confirming infantile spasms. Moreover, magnetic resonance was performed, showing complete agenesis of the corpus callosum. The patient was then transferred for an ophthalmoscopic examination, which evidenced multiple hypopigmented chorioretinal lesions corresponding to chorioretinal lacunae. Based on the clinical and radiological findings, the diagnosis of Aicardi syndrome was established, and treatment with anticonvulsive therapy and physiotherapy was initiated. This case report highlights the main characteristics that clinicians should consider to suspect this rare genetic condition, emphasizing the imaging and electroencephalographic findings.

Evaluation of seromas in postmastectomy breast reconstruction: A retrospective observational study.

BACKGROUND: To evaluate seroma complications, two techniques were carried out in breast reconstruction: conventional latissimus dorsi flap (CLD) and muscle-sparing latissimus dorsi flap (MSLD) after cancer-related mastectomy. METHODS: A total of 108 postmastectomy procedures were performed with autologous tissue reconstruction with latissimus dorsi flaps (LDs) between January 2016 and May 2020. The patients were divided into two groups. The first group was reconstruction with the CLD, and the second group was reconstruction with the MSLD. Forty (40) patients in the first group and 68 patients in the second group were analyzed. Seroma formation was evaluated as the primary outcome. RESULTS: The total number of seromas found in the donor area was 27, of which 45% (n = 18) were found with the CLD and 13.24% (n = 9) with the MSLD, with a difference of 31.76% in favor of the MSLD, with an 95% CI of 14-49 (p < 0.001). CONCLUSIONS: We found a significantly lower incidence of seroma as a complication in patients who underwent MSLD breast reconstruction compared with those who underwent CLD breast reconstruction.

Identification of Hazard and Socio-Demographic Patterns of Dengue Infections in a Colombian Subtropical Region from 2015 to 2020: Cox Regression Models and Statistical Analysis.

Dengue is a disease of high interest for public health in the affected localities. Dengue virus is transmitted by Aedes species and presents hyperendemic behaviors in tropical and subtropical regions. Colombia is one of the countries most affected by the dengue virus in the Americas. Its central-west region is a hot spot in dengue transmission, especially the Department of Antioquia, which has suffered from multiple dengue outbreaks in recent years (2015-2016 and 2019-2020). In this article, we perform a retrospective analysis of the confirmed dengue cases in Antioquia, discriminating by both subregions and dengue severity from 2015 to 2020. First, we conduct an exploratory analysis of the epidemic data, and then a statistical survival analysis is carried out using a Cox regression model. Our findings allow the identification of the hazard and socio-demographic patterns of dengue infections in the Colombian subtropical region of Antioquia from 2015 to 2020.

Prenatal ultrasound diagnostic approach to Omenn syndrome: case report / Aproximación diagnóstica ultrasonográfica prenatal al síndrome de Omenn: reporte de caso

Objective: To report the case of a pregnant woman with ultrasound diagnosis of altered fetal tegumental system and postnatal diagnosis of Omenn syndrome. Case presentation: A 27-year-old patient who presented at 31 weeks of gestation with prenatal ultrasound evidence of a fetus with significant scalp edema, echogenic amniotic fluid and scaly abdominal skin, with ichtyosis variant impression on diagnostic ultrasound. The baby was born with congenital erythroderma complicated with skin infection, and later developed septic shock and died. The genetic and pathologic workup led to the conclusion of Omenn syndrome. Conclusion: Omenn syndrome must be considered as part of the differential diagnoses when prenatal ultrasound shows findings of altered tegument system. Studies are required to assess the accuracy of ultrasound for prenatal diagnosis of erythroderma.

Objetivo: reportar el caso de una gestante con diagnóstico ultrasonográfico de alteración del sistema tegumentario fetal y diagnóstico posnatal de síndrome de Omenn. Presentación de caso: se presenta el caso de paciente de 27 años con embarazo de 31 semanas, con exploración ultrasonográfica prenatal que evidencia feto con edema significativo del cuero cabelludo, líquido amniótico ecogénico y descamación de la piel abdominal, con aproximación diagnóstica ultrasonográfica de variante de ictiosis. El recién nacido presentó eritrodermia congénita complicada con infección de piel, con posterior choque séptico y muerte. El estudio genético y patológico concluye síndrome de Omenn. Conclusión: el síndrome de Omenn debe ser tomado en cuenta en los diagnósticos diferenciales cuando en la ultrasonografía prenatal existan hallazgos ultrasongráficos de una alteración del sistema tegumentario. Se requieren estudios que evalúen la exactitud del ultrasonido en el diagnóstico antenatal de las eritrodermias.

Clinical outcome of patients with COVID-19 Pneumonia treated with corticosteroids and colchicine in Colombia.

BACKGROUND: To date, there is no specific antiviral therapy for severe acute respiratory syndrome Coronavirus 2 (SARS-CoV-2) that causes Coronavirus disease 2019 (Covid-19). Since there is no specific therapy against SARS-CoV2, current efforts aim to prevent contagion through public health measures and develop a protective vaccine. While waiting for the latter, it is necessary to evaluate the drugs that at least, in initial studies, suggested some degree of utility in the management of Covid-19 or its complications. The main objective of the study was to describe the clinical manifestations and outcomes of patients with severe Covid-19 Pneumonia treated with corticosteroids and colchicine. MATERIALS AND METHODS: A cross sectional study of 301 adult patients with Covid-19 Pneumonia confirmed by Real-Time Polymerase Chain Reaction for SARS-CoV2 (RT-PCR SARS-CoV2), Berlin protocol, who required hospitalization in three hospitals in Antioquia, Colombia. Patients were treated according to the institutional protocol (from March 20, 2020 to June 30, 2020) with corticosteroid if the patient required supplemental oxygen. From July 1, 2020, the management protocol changed with the addition of colchicine to all patients admitted to the institutions. The treatment was supervised and monitored by the same specialist in Infectology of the institutions. We describe the clinical manifestations and outcomes of the patients who received these treatments. The information of the patients was analyzed according to the outcome of interest (alive/dead) with univariate, bivariate, and multivariate measures to adjust the variables that presented statistical association. RESULTS: All patients had pneumonia documented by chest computed tomography with ground glass images and presented an alveolar pressure/inspired oxygen fraction (PaFi) less than 300. Three hundred one patients were included, 240 (79.7%) received corticosteroids, within these 145 (48.2%) received colchicine also, and the remaining 61 (20.3%) patients did not receive corticosterioids or colchicine. Mortality in the group that received colchicine was lower compared to the group that did not receive it (9.6 vs 14.6%, p-value = 0.179). CONCLUSIONS: Treatment with corticosteroids and colchicine for managing patients with severe Covid-19 Pneumonia was associated with low mortality at the hospital level. Randomized, placebo-controlled studies are required to evaluate the effect of corticosteroids and colchicine on complications or death from Covid-19.

Mental health interventions for college and university students during the COVID-19 pandemic: A critical synthesis of the literature.

BACKGROUND: The aim of the study is to compare the emotional effects of COVID-19 among three different groups, namely: health personnel, medical students, and a sample of the general population. METHODS: 375 participants were recruited for this study, of which 125 were medical students (preclinical studies, 59; clinical studies, 66), 125 were health personnel (COVID-19 frontline personnel, 59; personnel not related with COVID-19, 66), and 125 belonged to the general population. The PHQ-9, GAD-7, and CPDI scales were used to assess the emotional impact. A multinomial logistic regression was performed to measure differences between groups, considering potential confounding factors. RESULTS: Regarding CPDI values, all other groups showed reduced values compared to COVID-19 frontline personnel. However, the general population, preclinical and clinical medical students showed increased PHQ-9 values compared to COVID-19 frontline personnel. Finally, confounding factors, gender and age correlated negatively with higher CPDI and PHQ-9 scores. CONCLUSIONS: Being frontline personnel is associated with increased COVID-19-related stress. Depression is associated, however, with other groups not directly involved with the treatment of COVID-19 patients. Female gender and younger age correlated with COVID-19-related depression and stress.

Intervenciones para la salud mental de estudiantes universitarios durante la pandemia por COVID-19: una síntesis crítica de la literatura / Mental health interventions for college and university students during the COVID-19 pandemic: a critical synthesis of the literature

RESUMEN Introducción: Los estudiantes de educación superior son una población vulnerable a los trastornos mentales, más aún durante la pandemia por COVID-19. Su salud mental se ha visto afectada por el confinamiento, las dificultades en el desarrollo de las actividades académicas y las exigencias de las nuevas modalidades pedagógicas. Se planteó entonces la pregunta: en las instituciones de educación superior, ¿cuáles acciones en torno a a) promoción y prevención, b) atención a síntomas mentales y c) adaptaciones pedagógicas pueden desarrollarse con el fin de mejorar la salud mental de sus estudiantes? Métodos: Síntesis crítica a partir de la revisión sistemática de la literatura. Se realizó la búsqueda de artículos científicos de alcance descriptivo, analítico, experimental o evaluativo, así como recursos web de organizaciones relacionadas con el tema. Se realizó una síntesis en función de los 3 focos de la pregunta mediante comparación constante, hasta realizar la agrupación de acciones por similitud en los actores que las ejecutarían y recibirían. Se anticipó una baja calidad de la evidencia, por lo que no se realizó evaluación estandarizada. Resultados: Se exploraron 68 artículos y 99 recursos web. Después de la revisión del texto completo se incluyeron 12 artículos científicos y 11 recursos web. Como lineamentos generales, se encontró que la propuesta más frecuente es el diseño de un programa estructurado específico para el tema de salud mental en las instituciones educativas, que sea multidisciplinario, incluyente, dinámico y sensible a la cultura. Las acciones deben ser divulgadas periódicamente para que los estudiantes y demás miembros de la comunidad educativa las tengan claras, e idealmente se propone mantenerlas hasta el periodo pospandémico e incluir a los egresados. Para a) la promoción y prevención, se encontró la psicoeducación por vía electrónica, donde se expliquen estilos de vida saludable, reacciones emocionales en pandemia, estrategias de afrontamiento y signos de alarma. Se propone la participación de los pares como estrategia de apoyo y espacios de interacción social que no se enfoquen únicamente en aspectos académicos. Se reporta la necesidad de cribar síntomas mentales por medio de envío frecuente de formularios en línea o aplicaciones móviles, donde también se indague por la satisfacción de las necesidades básicas y tecnológicas. En cuanto a b) atención de síntomas mentales, una de las acciones que se encontró con mayor frecuencia es disponer de un centro de consultoría que sea capaz de realizar atención en salud mental por vía telefónica, por tecnologías e incluso presencial, con atención permanente las 24 h o equipos de respuesta rápida ante una situación de crisis, como la conducta suicida y la violencia doméstica. Para c) las adaptaciones pedagógicas, se señala como requisito indispensable la comunicación fluida para tener instrucciones claras sobre el desarrollo de las actividades académicas para disminuir la incertidumbre y, por ende, la ansiedad y favorecer la gestión del tiempo por el estudiante. Los profesores y pedagogos de la institución pueden ofrecer asesorías directas (por videollamadas o reuniones de grupos en línea) para proveer apoyo en hábitos de estudios, materias propias de cada carrera y salud mental. Conclusiones: Los recursos incluidos proponen que la institución educativa cree un programa que aborde específicamente la salud mental de los estudiantes. Esta síntesis puede proveer lineamientos que faciliten la toma de decisiones, sin perder de vista que la institución y el estudiante están inmersos en un contexto complejo, con circunstancias y otros actores en varios niveles que también intervienen en la salud mental. Se requieren investigaciones sobre la evolución de la situación de salud mental y el efecto de las acciones que se vayan tomando.

ABSTRACT Background: College and university students are a population vulnerable to mental disorders, especially during the COVID-19 pandemic. Their mental health has been affected by confinement, difficulties in the development of academic activities, and the demands of new pedagogical modalities. We aimed to respond to the question: what are the actions around a) promotion and prevention, b) mental symptoms care, and c) pedagogical adaptations that can be developed in order to improve the mental health of college and university students? Methods: We conducted a critical synthesis from a systematic review of the literature. A search was made for scientific articles with descriptive, analytical, empirical or evaluative designs, as well as web resources of organizations related to the topic. A synthesis was carried out based on the three aspects of the question by means of a constant comparative method, until the aggregation of actions by similarity in the actors. We anticipated low evidence quality; therefore, a standardized evaluation was not performed. Results: We explored 68 articles and 99 web resources. After reviewing the full text, 12 scientific articles and 11 web resources were included. As general guidelines, we found that the most frequent suggestion is the design of a specific structured mental health program within universities, one that should be multidisciplinary, inclusive, dynamic and culturally sensitive. All actions taken by the university should be reported and published periodically so that students and other members of the university community are clear about them. Ideally, it is suggested to keep them until the post-pandemic period and include alumni. Regarding a) promotion and prevention, digital psychoeducation was recommended, with information about healthy lifestyles, common emotional reactions to epidemics, coping strategies and warning signs. Peer participation is suggested as a support strategy, as well as spaces for social interaction that focus not only on academic aspects but also on leisure. Screening for mental symptoms is suggested through frequent submission of online forms or mobile applications. In addition to mental health, it is important to inquire about the degree of satisfaction of basic and technology-related needs. For b) the care of mental symptoms, one of the actions commonly identified was a consulting centre that can provide mental health care by telephone, by technology, and even in person -if required -, with permanent availability with rapid response teams for crisis situations, such as suicidal behavior and domestic violence. For c) pedagogical adaptations, fluent communication is an indispensable requirement; having clear instructions on academic activities can reduce uncertainty and therefore anxiety. The teaching and pedagogical staff at the institution can offer direct advice (via video calls or online group meetings) to provide support in study habits, degree-specific material and mental health. Conclusions: Included resources suggest the creation of a program that specifically addresses the mental health of students. This synthesis can provide guidelines that facilitate decision-making by the university, without losing sight of the fact that the institution and the student are immersed in a complex context, with circumstances and other actors at various levels that also intervene in mental health. Research is required on the evolution of the mental health situation and the effect of the actions that are being taken.

Multicolor Fluorescent Graphene Oxide Quantum Dots for Sensing Cancer Cell Biomarkers.

Onion-like carbon nanoparticles were synthesized from diamond nanoparticles to be used as the precursor for graphene oxide quantum dots. Onion-like carbon nanoparticles were exfoliated to produce two types of nanoparticles, graphene oxide quantum dots that showed size-dependent fluorescence and highly stable inner cores. Multicolor fluorescent quantum dots were obtained and characterized using different techniques. Polyacrylamide gel electrophoresis showed a range of emission wavelengths spanning from red to blue with the highest intensity shown by green fluorescence. Using high-resolution transmission electron microscopy, we calculated a unit cell size of 2.47 Å in a highly oxidized and defected structure of graphene oxide. A diameter of ca. 4 nm and radius of gyration of ca. 11 Å were calculated using small-angle X-ray scattering. Finally, the change in fluorescence of the quantum dots was studied when single-stranded DNA that is recognized by telomerase was attached to the quantum dots. Their interaction with the telomerase present in cancer cells was observed and a change was seen after six days, providing an important application of these modified graphene oxide quantum dots for cancer sensing.

Childhood onset homozygous recessive GDAP1 (p.Pro231Leu) mutation in a 9-year-old puerto rican pediatric female with axonal Charcot-Marie-Tooth disease: A case report.

Charcot-Marie-Tooth disease (CMT) is a progressive hereditary neuromuscular neuropathy with pathology in the myelin sheath or the axon. CMT caused by mutations in the Ganglioside-induced differentiation associated protein 1 (GDAP1) gene has been described by a spectrum of phenotypic presentations. GDAP1 is a mitochondrial protein responsible for protecting neuronal bodies from oxidative stress. It is associated with axonal and demyelinating pathophysiology with recessive and dominant modes of inheritance.We describe a case of a 9-year-old Puerto Rican female with clinical and electrodiagnostic results compatible with an axonal sensory-motor neuropathy where a genetic test describes a homozygous GDAP1 missense mutation at the c.692C>T (p.Pro231Leu), previously undetected in a pediatric Latino patient. Mutations in GDAP1 have been previously described in Tunisian, Old Order Amish, European and Japanese families with varying modes of inheritance. To our knowledge, this homozygous variant presentation of the GDAP1 gene is the first to be described in a pediatric Puerto Rican patient without a family history of hereditary sensory motor neuropathy.

Dexamethasone vs methylprednisolone high dose for Covid-19 pneumonia.

BACKGROUND: There is no effective therapy for the severe acute respiratory syndrome by coronavirus 2 (SARS-CoV2) responsible for the Coronavirus disease 2019 (Covid-19). To date, dexamethasone has shown a decrease in mortality in patients who require oxygen, especially those with invasive mechanical ventilation. However, it is unknown if another corticosteroid can be used, the optimal dose and its duration, to achieve a better clinical outcome. The objective of the study was to compare the differences in clinical outcome and laboratory results in hospitalized patients with severe SARS-CoV2 Pneumonia treated with dexamethasone at 6 mg doses versus patients treated with high-dose methylprednisolone. MATERIALS AND METHODS: Ambispective cohort study with survival analysis of 216 patients diagnosed with severe Covid-19 pneumonia confirmed by polymerase chain reaction for SARS-CoV2 by Berlin protocol, who were hospitalized in a high-complexity clinic in Medellín, Colombia. The patients should also have supplementary oxygen and radiological confirmation of Pneumonia by chest tomography. Sample size was not calculated since the total population that met the inclusion criteria was evaluated. 111 patients were treated with the institutional protocol with intravenous dexamethasone 6 mg QD for seven to 10 days if they required oxygen. Since September 15, 2020, the hospitalization protocol of the clinic was modified by the Infectious Diseases and Pulmonology service, recommending a high dose of methylprednisolone of 250 to 500 mg every day for three days with a subsequent change to oral prednisone 50 mg every day for 14 days. The protocol was not applied in the intensive care unit, where dexamethasone continued to be administered. The clinical outcome and differences in laboratory results of the patients who received dexamethasone vs. the prospective cohort that received methylprednisolone from September 15 to October 31, 2020, were evaluated. Follow-up was carried out by outpatient consultation one month after discharge or by telephone, inquiring about readmission or living-dead status. RESULTS: 216 patients had Covid-19 pneumonia documented by ground-glass imaging and alveolar pressure / inspired oxygen fraction (PaFi) less than 300. 111 patients received dexamethasone (DXM) and 105 received methylprednisolone (MTP). Patients in the DXM group evolved to severe ARDS in a higher proportion (26.1% vs 17.1% than the MTP group). Upon completion 4 days of treatment with parenteral corticosteroid, laboratory markers of severity decreased significantly in the group that received MTP, CRP 2.85 (2.3-3.8) vs 7.2 (5.4-9.8), (p-value < 0.0001), D-dimer 691 (612-847) vs 1083 (740-1565) (p-value = 0.04) and DHL 273 (244-289) vs 355 (270.6-422) (p-value = 0.01). After starting the corticosteroid, transfer to the intensive care unit (4.8% vs. 14.4%) and mortality (9,5% vs. 17.1%) was lower in the group that received MTP. Recovery time was shorter in patients treated with MTP, three days (3-4) vs. DXM 6 days (5-8) (p-value < 0.0001). At 30-day follow-up, 88 (92.6%) were alive in MTP vs 58 (63.1%) of those who received dexamethasone. CONCLUSIONS: In this study, the treatment of severe Covid-19 Pneumonia with high-dose methylprednisolone for three days followed by oral prednisone for 14 days, compared with 6 mg dexamethasone for 7 to 10 days, statistically significantly decreased the recovery time, the need for transfer to intensive care and the severity markers C-reactive protein (CRP), D-dimer and LDH. Randomized controlled studies with methylprednisolone are required to corroborate its effect, and studies in a population hospitalized in intensive care wards.

Cervical mesonephric adenocarcinoma: A case report of a rare gynecological tumor from embryological remains of the female genital tract / Adenocarcinoma mesonéfrico cervical: Relato de caso de um tumor ginecológico raro de restos embriológicos do trato genital feminino

Abstract Introduction Malignant mesonephric tumors are uncommon in the female genital tract, and they are usually located where embryonic remnants of Wolffian ducts are detected, such as the uterine cervix. The information about these tumors, their treatment protocol, and prognosis are scarce. Case report A 60-year-old woman with postmenopausal vaginal bleeding was initially diagnosed with endometrial carcinoma. After suspicion co-testing, the patient underwent a loop electrosurgical excision of the cervix and was eventually diagnosed with mesonephric adenocarcinoma. She was subjected to a radical hysterectomy, which revealed International Federation of Gynecology and Obstetrics (FIGO) IB1 stage, and adjuvant radiotherapy. The follow-up showed no evidence of recurrence after 60 months. Conclusion We present the case of a woman with cervical mesonephric adenocarcinoma. When compared with the literature, this case had the longest clinical follow-up without evidence of recurrence, which reinforces the concept that these tumors are associated with a favorable prognosis if managed according to the guidelines defined for the treatment of patients with cervical adenocarcinomas. Though a rare entity, it should be kept in mind as a differential diagnosis for other cervical cancers.

Cervical Mesonephric Adenocarcinoma: A Case Report of a Rare Gynecological Tumor from Embryological Remains of the Female Genital Tract.

INTRODUCTION: Malignant mesonephric tumors are uncommon in the female genital tract, and they are usually located where embryonic remnants of Wolffian ducts are detected, such as the uterine cervix. The information about these tumors, their treatment protocol, and prognosis are scarce. CASE REPORT: A 60-year-old woman with postmenopausal vaginal bleeding was initially diagnosed with endometrial carcinoma. After suspicion co-testing, the patient underwent a loop electrosurgical excision of the cervix and was eventually diagnosed with mesonephric adenocarcinoma. She was subjected to a radical hysterectomy, which revealed International Federation of Gynecology and Obstetrics (FIGO) IB1 stage, and adjuvant radiotherapy. The follow-up showed no evidence of recurrence after 60 months. CONCLUSION: We present the case of a woman with cervical mesonephric adenocarcinoma. When compared with the literature, this case had the longest clinical follow-up without evidence of recurrence, which reinforces the concept that these tumors are associated with a favorable prognosis if managed according to the guidelines defined for the treatment of patients with cervical adenocarcinomas. Though a rare entity, it should be kept in mind as a differential diagnosis for other cervical cancers.

Familial Hyperckemia and Calf Hypertrophy Secondary to a Caveolin-3 Mutation.

ABSTRACT: Idiopathic hyperckemia has been described as persistent serum creatine kinase elevation at least 1.5 times the upper limit of normal in individuals with otherwise normal laboratory findings and neurological examination. This type of hyperckemia encompasses both sporadic and familial cases, which have been found to be asymptomatic or subclinical, presenting with mild symptoms, such as myalgias or cramps. Genetic causes of hyperckemia have been rarely described. The authors aim to describe a benign autosomal dominant condition caused by a rare mutation in the caveolin gene. Caveolin gene encodes for structural membrane proteins in muscle. The purpose of this article was to discuss the presentation, pathophysiology, and diagnosis of familial hyperckemia secondary to a relatively unknown mutation in caveolin-3 gene.
