RESUMEN
Intravascular ultrasound (IVUS) has become crucial in contemporary percutaneous coronary interventions (PCIs), offering detailed two-dimensional (2D) arterial wall visualization. Current guidelines consider it valuable for guiding coronary stent placement, especially in complex cases like the left main (LM) artery, allowing a comprehensive assessment of vessel characteristics and stent performance. There are some studies that highlight the potential impact of IVUS on acute myocardial infarction (AMI) management, notably improving outcomes. This case involves a 37-year-old man who experienced an AMI, necessitating the use of IVUS to ascertain the underlying cause of his acute coronary syndrome (ACS). This approach was essential for guiding appropriate treatment and ultimately led to successful stent implantation.
RESUMEN
Coronary artery bypass graft (CABG) surgery has a major role in the management of obstructive coronary artery disease, especially in patients with diabetes or multiple vessel disease. Currently, in the USA, the annual incidence rate of CABG has been reported to be approximately 400,000. Overall, gastrointestinal (GI) complications occur in less than 2% of patients undergoing open-heart surgery. Acute colonic pseudo-obstruction, also known as Ogilvie's syndrome, is a disorder characterized by dilatation of the colon in the absence of an anatomic lesion that obstructs the flow of intestinal contents. This condition occurs in 0.06% of patients following cardiac surgery, and in CABG patients, the reported incidence is approximately 0.046%. In this report, we discuss a case of a patient who developed Ogilvie's syndrome after undergoing CABG.
RESUMEN
Myxedema Coma (MC) is a life-threatening medical emergency that occurs as a severe complication of untreated or poorly managed hypothyroidism. Prompt diagnosis is crucial as the condition can rapidly deteriorate and lead to life-threatening complications. Timely treatment of myxedema coma with intravenous levothyroxine is the cornerstone of treatment, along with glucocorticoids to support adrenal function. This condition is associated with cardiovascular manifestations that contribute to its high mortality rate. The heart in hypothyroidism typically shows reversible dysfunction that can be corrected with hormonal supplementation, and in some cases, requires inotropic and aminergic support. This case involves a patient who was admitted to the intensive care unit with suspected MC, and necessitated life-saving hormonal and cardiovascular support to manage the condition.
RESUMEN
Cardiac platypnea-orthodeoxia is a unique clinical syndrome characterized by dyspnea and deoxygenation when moving from a supine to an upright position. In this case report, we detail the experience of a 78-year-old male with persistent hypoxemia following a paradoxical embolic ischemic stroke. Despite proper management of his respiratory symptoms, the patient continued to be affected by marked dyspnea and hypoxemia, particularly when upright or in a right-sided decubitus position. Subsequent investigation revealed that his hypoxemia was a result of cardiac platypnea-orthodeoxia syndrome (POS). This condition was attributed to the enlargement of his aortic root and ascending aorta, coupled with a counterclockwise rotation of the heart axis. These factors facilitated a flow-directed, right-to-left interatrial shunt through a patent foramen ovale, even in the absence of elevated right heart pressures.
RESUMEN
We present an intriguing and rare case of a 71-year-old male who presented with a non-ST elevation myocardial infarction (NSTEMI). Initial coronary angiography revealed severe and unusual systolic extrinsic compression of the left main coronary artery (LM), warranting further advanced imaging investigations. Computed tomography angiography (CTA) and transesophageal echocardiography (TEE) were employed to determine the underlying cause, which was identified as a contained aortic rupture leading to the formation of a pseudoaneurysm in the left coronary sinus of Valsalva and aortic root. This condition was found to be a sequela of previously undiagnosed endocarditis, likely secondary to lower extremity osteomyelitis and bacteremia, for which the patient received prolonged intravenous (IV) antibiotic therapy. This case highlights the critical role advanced imaging techniques play in accurately diagnosing and characterizing complex cardiovascular abnormalities, enabling early intervention and optimizing patient outcomes. Healthcare providers should remain vigilant for such atypical presentations to ensure timely and appropriate management.
RESUMEN
Chronic kidney disease-associated pruritus is itching directly related to kidney disease that cannot be explained by any other condition. Despite technological advances in the different aspects of dialysis sessions and the best treatment for chronic kidney disease patients, it is still a common problem in our patients. The many complex physiological mechanisms involved, the different hypotheses made over the years on the aetiology of the condition, and the great clinical variability may partially explain the limited knowledge about this problem and the difficulties in treating it. The presence of all these factors leads to the persistence of unpleasant symptoms, which must affect the disease burden and quality of life of kidney patients. Through the presentation of an illustrative clinical case, the aim of this review article is to highlight the need for adequate diagnosis and an improved approach to all aspects of chronic kidney disease-associated pruritus, in view of the heavy burden of the disease and the huge impact on the patient's quality of life.
RESUMEN
Identifying underlying bleeding diathesis that is amenable to medical therapy must be determined to provide timely treatment and minimize morbidity. Nasal bleeding is viewed as an annoyance by most who suffer from its episodes. However, it can at times be a baleful ailment that can compromise a patient's airway, breathing, and circulation, which can result in death. A 75-year-old Hispanic man presented with life-threatening epistaxis and was ultimately diagnosed with multiple myeloma (MM). The patient suffered profuse bleeding and hemodynamic compromise, requiring endoscopic nasal packing, red cell transfusions, platelet transfusions, and right external carotid artery angiogram with maxillary arteries embolization prior to chemotherapy. Embolization of maxillary arteries helped to stabilize the patient to diagnose MM and start definitive management with chemotherapy. On data review, we could not find another case with severe epistaxis secondary to MM, which was controlled with endovascular embolization. This case highlights the difficulties in managing a rare condition and the importance of a multidisciplinary approach in patients who present with life-threatening epistaxis secondary to plasma cell dyscrasia.
RESUMEN
Syncope is a common cause of emergency department visits. Physicians must scrutinize for life-threatening causes to avoid patient morbidity and mortality. Clinical decision rules are used to stratify risks and guide the course of action, including the need for further testing. This is the case of a 83-year-old man was brought to the emergency department after a 5-minute episode of sudden loss of consciousness. Vital signs showed hypotension and physical examination was unremarkable. Despite Wells score of 0, clinical suspicion for pulmonary embolism persisted, for which further testing was pursued. D-dimer was elevated at 13.77 mcg/mL and a chest computed tomography with angiography showed an extensive bilateral pulmonary embolism involving the distal right and left main pulmonary arteries. He was started on full-dose anticoagulation. This case exemplifies the need of high clinical suspicion along with the importance of applying predictive scores for diagnosing unusual causes of syncope.

We present a new measurement of the bottom quark mass in the MS[over ¯] scheme at the renormalization scale of the Higgs boson mass from measurements of Higgs boson decay rates at the LHC: m_{b}(m_{H})=2.60_{-0.31}^{+0.36} GeV. The measurement has a negligible theory uncertainty and excellent prospects to improve at the HL-LHC and a future Higgs factory. Confronting this result and m_{b}(m_{b}) from low-energy measurements and m_{b}(m_{Z}) from Z-pole data, with the prediction of the scale evolution of the renormalization group equations, we find strong evidence for the "running" of the bottom quark mass.
RESUMEN
Significant (moderate or severe) paravalvular leak (PVL) after transcatheter aortic valve replacement (TAVR) remains a common phenomenon and has been associated with decrease survival and quality of life. Transcatheter valve embolization and migration (TVEM) is a rare post-TAVR complication that can occur in 1% of cases and has been associated with worse patient outcomes. Valve embolization or migration into the left ventricle can result in significant PVL causing hemodynamic instability, shock, heart failure, and hemolytic anemia. Although this complication most commonly occurs in the acute setting (90%) within 4 hours of TAVR, it can also present late (4 hr-43 days later) in 10% of cases. There are no clear guidelines as to how this condition should be managed; however, several percutaneous bailout techniques exist that can ultimately spare the patient from emergent cardiovascular surgery. We present a rare case of late ventricular transcatheter aortic valve migration 3 days after TAVR causing severe PVL and heart failure symptoms that was successfully treated using the percutaneous "double snare" technique.
RESUMEN
The success of hemodialysis (HD) treatments has been evaluated using objective measures of analytical parameters, or machine-measured parameters, despite having available validated instruments that assess patient perspective. There is an emerging interest regarding the use and relevance of patient-related outcomes (PROs). Electronic PROs (ePROs) involve the use of electronic technology, provide rapid access to this information, and are becoming more widely used in clinical trials and studies to evaluate efficacy and safety. Despite the scarce literature, this review suggests that ePROs are useful in providing a more customized and multidimensional approach to patient management and in making better clinical decisions in relevant aspects such as vascular access, duration and frequency of dialysis sessions, treatment of anemia, mental health, fatigue, and quality of life. The purpose of this review is to raise interest in the systematic use of ePROs in HD and to promote the development of studies in this field, which can respond to the gaps in knowledge and contribute to the implementation of the use of ePROs through new technologies, helping to improve the quality of health care.
RESUMEN
ANTECEDENTES Y OBJETIVOS: La acidosis tubular renal distal (ATRd) es una enfermedad minoritaria, de origen genético o adquirido, caracterizada por una incapacidad de excreción urinaria de hidrogeniones (H+), hipobicarbonatemia, hipercloremia, hipocitraturia y habitualmente hipokaliemia e hipercalciuria. Las formas genéticas suelen diagnosticarse en los primeros meses de vida y su tratamiento consiste en suplementos de álcali encaminados a evitar las consecuencias clínicas a largo plazo, sobre todo la enfermedad renal crónica (presente en algunas series hasta en el 82% de los pacientes) y la enfermedad ósea asociada. Se desarrolló una encuesta multirrespuesta cerrada de 10 preguntas encaminada a conocer aspectos epidemiológicos, diagnósticos, del manejo clínico y terapéutico, dentro del colectivo de nefrólogos españoles. MATERIALES Y MÉTODOS: Encuesta distribuida a los asistentes a un foro científico sobre ATRd durante el congreso de 2019 de la Sociedad Española de Nefrología (SEN); las respuestas se recogieron a la salida del mismo. Los resultados se analizaron con un test estadístico paramétrico estableciéndose el porcentaje de cada respuesta a las 10 preguntas. RESULTADOS: De entre los que respondieron a la encuesta, el 44,4 y el 37,7% no atendieron a ningún paciente con ATRd en el último año ni en los tres anteriores, respectivamente. Cuando se sospecha la patología, el diagnóstico genético confirmatorio se realiza solo en el 13,3% de los casos y el estudio familiar solo en el 11,1%. Solo el 26,6% afirman que el control metabólico es excelente, bueno o muy bueno, y el 69% piensan que el cumplimiento terapéutico es regular, malo o muy malo. CONCLUSIONES: La encuesta ha puesto de manifiesto el relativo desconocimiento de esta patología, así como la baja satisfacción con el control metabólico y el pobre cumplimiento terapéutico, lo cual puede conllevar una mayor severidad en la enfermedad renal y ósea asociadas a la ATRd
BACKGROUND AND OBJECTIVES: dRTA is a genetic or acquired rare disease, characterized by an unability to excrete hydrogens (H+) into urine, hypobicarbonatemia, hyperchloremia, and frequently hypercalciuria and hypokalaemia. Genetic forms are usually diagnosed during the first months of life and its treatment is based on providing alkali supplements in order to prevent long term clinical consequences, particularly chronic kidney disease (described in some cohorts up to 82% of dRTA patients) and the associated bone disease. A 10 queries multi choice closed response survey was designed to know more about epidemiological, diagnostics, clinical management and therapeutical issues of this disease among Spanish nephrologists. MATERIALS AND METHODS: This survey was delivered to the attendees to a scientific meeting on dRTA at the Spanish Nephrology Society congress in 2019. Surveys were collected at the end of this dRTA event. Results were analyzed by using a parametric statistical test, obtaining the percentage of each response for the 10 questions. RESULTS: Among the survey responders, 44.4% and 37.7% did not visit any dRTA patient during the 1st and 3rd last year respectively. When having a suspicious diagnose, confirming genetic diagnostic test is only performed on the 13.3% of cases and pedigree studies only on 11.1%. Only a 26.6% confirms that metabolic control is excellent, good or very good, and 69% of the responders believe that treatment compliance is not bad, bad or very bad. CONCLUSIONS: This survey enhances the fact that dRTA is not a well known entity, satisfaction with metabolic control is poor and compliance is low. All these factors can lead to a higher severity of renal and bone diseases associated to dRTA

RESUMEN
ANTECEDENTES Y OBJETIVO: Recientemente, se han desarrollado en España las Unidades de Enfermedad Renal Crónica Avanzada (UERCA) con el objetivo de ofrecer una mayor calidad de vida a los pacientes con ERCA, mejorar su supervivencia y disminuir la morbilidad en esta fase de la enfermedad. Al día de hoy, hay poca evidencia en la literatura española e internacional con respecto a la estructura y cómo conseguir estos objetivos en las UERCA. Desde el grupo de trabajo ERCA de la Sociedad Española de Nefrología (SEN) se impulsa este proyecto para mejorar la atención a los pacientes ERCA a través de la definición de estándares de calidad para el funcionamiento de las UERCA. MATERIAL Y MÉTODOS: Se conformó una propuesta inicial de estándares de calidad sobre el funcionamiento de las UERCA a través de la consulta de principales fuentes de referencias y el asesoramiento de un grupo de trabajo de expertos a través de reuniones presenciales y no presenciales. A partir de esta propuesta inicial de estándares, se diseñó y envío una encuesta vía correo electrónico a 121 especialistas de nefrología y profesionales de enfermería con experiencia en UERCA españolas para conocer entre otros, la idoneidad de cada estándar, es decir, su obligatoriedad o recomendación como estándar. Se permitió acceso a la encuesta entre el 16 de julio de 2018, hasta el 26 de septiembre de 2018. RESULTADOS: Participaron un total de 95 (78,5%) profesionales de los 121 que fueron invitados a participar. De éstos, 80 fueron especialistas en nefrología y 15 profesionales de enfermería, obteniéndose una variada representación de profesionales de la geografía española. Tras analizar las opiniones de estos participantes, los estándares quedaron definidos a un total de 68, 37 de ellos (54,4%) obligatorios y 31 de ellos (45,5%) recomendables. Además, se observó que el volumen de pacientes atendidos en las UERCA se sitúa usualmente por encima de los 100 pacientes, y que el criterio de derivación por regla general está por debajo de 25-29 mL/min/1,73 m2 de filtración glomerular. CONCLUSIONES: Este trabajo constituye una primera propuesta de estándares de calidad para el funcionamiento de una UERCA en España. La definición de estos estándares ha permitido establecer las bases para la estandarización de la organización de las UERCA, y trabajar posteriormente en la configuración de un manual de estándares para la acreditación de estas Unidades
BACKGROUND AND OBJECTIVE: Recently, the Advanced Chronic Kidney Disease Units (UERCA, in Spanish) have been developed in Spain to offer a better quality of life to patients with advanced chronic kidney disease (ACKD), improving their survival and reducing morbidity in this phase of the disease. Nowadays, there is not much evidence in the Spanish and international literature regarding the structure and how to achieve these objectives in the UERCA. From the ERCA working group of the Spanish Society of Nephrology (SEN), this project is promoted to improve care for ERCA patients through the definition of quality standards for the operation of the UERCA. MATERIAL AND METHODS: An initial proposal for quality standards concerning the operation of the UERCA was configured through consultation with the main sources of references and the advice of an expert working group through face-to-face and telematic meetings. Base on this initial proposal of standards, a survey was conducted and sent it via email to 121 nephrology specialist and nursing professionals with experience in Spanish UERCA to find out, among others, the suitability of each standards, that is, its mandatory nature or recommendation as standards. The access to the survey was allowed between July 16th, 2018, until September 26th, 2018. RESULTS: A total of 95 (78.5%) professionals participated out of the 121 who were invited to participate. Of these, 80 of the participants were nephrology specialists and 15 nursing professionals, obtaining a varied representation of professionals from the Spanish geography. After analyzing the opinions of these participants, the standards were defined to a total of 68, 37 of them (54.4%) mandatory and 31 of them (45.5%) recommended. Besides, it was observed that the volume of patients attended in the UERCA is usually above 100 patients, and the referral criteria is generally below 25-29 mL/min/1.73 m2 of glomerular filtration. CONCLUSIONS: This work constitutes a first proposal of quality standards for the operation of UERCA in Spain. The definition of these standards has made it possible to establish the bases for the standardization of the organization of UERCA, and to subsequently work on the configuration of a standards manual for the accreditation of ERCA Units

El fitato o myo-inositol-1,2,3,4,5,6-hexakis dihidrogenofostato (InsP6) es un compuesto fosforado de origen natural que está presente en numerosos alimentos, principalmente en legumbres, cereales integrales y frutos secos. Los pacientes con enfermedad renal crónica (ERC) experimentan una mortalidad por enfermedad cardiovascular hasta 30veces mayor que la población en general. Las calcificaciones vasculares (CV) contribuyen directamente en la morbimortalidad general, y de forma especial en la ERC. Esta elevada mortalidad se debe, en parte, a la elevación en los niveles de fósforo en sangre. Por ello, el control de fósforo en la dieta es fundamental. El fósforo dietético puede clasificarse en función de su estructura en fósforo orgánico (origen vegetal y animal) e inorgánico (conservantes y aditivos). El fósforo de origen vegetal (legumbres y frutos secos), principalmente asociado a InsP6, es menos absorbible por el tracto gastrointestinal humano siendo la biodisponibilidad del fósforo procedente de estos alimentos muy baja. Datos recientes indican que la restricción impuesta de alimentos que contienen fosfatos vegetales puede comprometer el aporte adecuado de nutrientes que tienen un efecto beneficioso en la prevención de episodios cardiovasculares, como pueda ser la fibra o al propio InsP6 presente en frutos secos y legumbres. Estudios experimentales en animales y observacionales en humanos sugieren que el InsP6 puede prevenir la litiasis, las CV y proteger de la osteoporosis. En conclusión, creemos necesario realizar estudios prospectivos para elucidar los posibles beneficios y riesgos de una dieta rica en fitato (InP6) en la ERC o de su uso como fármaco intravenoso en pacientes en hemodiálisis (AU)
Phytate, or myo-inositol 1,2,3,4,5,6-hexakis dihydrogen phosphate (InsP6), is a naturally occurring phosphorus compound that is present in many foods, mainly legumes, whole grains and nuts. Patients with chronic kidney disease (CKD) have cardiovascular disease mortality up to 30times higher than the general population. Vascular calcifications (VCs) directly contribute to overall morbidity and mortality, especially in CKD. In part, this high mortality is due to elevated levels of phosphorus in the blood. Therefore, control of dietary phosphorus is essential. Dietary phosphorus can be classified according to its structure in organic phosphorus (plant and animal) and inorganic (preservatives and additives). Plant-phosphorus (legumes and nuts), mainly associated with InsP6, is less absorbable by the human gastrointestinal tract as the bioavailability of phosphorous from plant-derived foods is very low. Recent data indicate that restriction of foods containing plant phosphates may compromise the adequate supply of nutrients that have a beneficial effect in preventing cardiovascular events, such as InsP6 or fibre found in legumes and nuts. Experimental studies in animals and observational studies in humans suggest that InsP6 can prevent lithiasis and VCs and protect from osteoporosis. In conclusion, we need prospective studies to elucidate the potential benefits and risks of phytate (InsP6) through the diet and as an intravenous drug in patients on haemodialysis (AU)

The aim of this study was to determine whether Human Papillomavirus was present in tongue and periodontium of periodontally healthy and diseased women who had genital lesions caused by the virus. Thirty non-menopausal women, systemically healthy and diagnosed with gynecological HPV lesions, were referred by the Gynecology Service Department of the University Maternal Neonatal Hospital of the City of Cordoba. Anamnesis, oral mucosa examination and periodontal clinical assessment were performed. Three brush samples were taken per patient: two from the same periodontal location (external epithelium of the gum and internal epithelium of the periodontal sulcus/pocket), and the third from the tongue. The 90 samples were submitted to Pap cytology and Polymerase Chain Reaction. The data were statistically analyzed by "Chi Square Test" (χ2) and "Kappa Index" (κ). High prevalence of HPV was found in the tongue (30%) and periodontal tissues (15%). High risk (HR) genotype -16 was detected with the highest percentage (67%), and genotypes -52 and -6 were also detected. Whenever HPV was present in periodontal location, it was also identified in the tongue of the same patients, of whom 88.89% reported that they practiced oral sex. Is worth noting the clinical finding of stomatologic lesions compatible with foliate papillitis in patients with positive intraoral HPV. High prevalence of HPV was found in the female population in Cordoba, with genotype -16 being detected at the highest percentage. No positive correlation was found between HPV and higher incidence and severity of periodontal lesions.

El objetivo del estudio fue identificar la presencia del virus Papiloma Humano en lengua y periodonto de mujeres sanas y enfermas periodontales con lesiones genitales del mismo. Se evaluarontreinta mujeres, no menopáusicas, de entre 18 y 50 años de edad, derivadas del Servicio de Ginecología del Hospital Universitario Materno Neonatal de la ciudad de Córdoba, sistémicamentesanas y con diagnóstico gineco lógico de lesiones por HPV. Se realizó, anamnesis, inspec ción de mucosas bucales, examen clínico periodontal y la toma de tres escobillados por paciente, dos de un mismo sitio periodontal (epitelio externo de encía y epitelio interno del surco/bolsa periodontal) y el otro de lengua. Las 90 muestras obtenidas fueron sometidas a estudios citológicos de Papanicolau y a estudios moleculares de amplificación de ácidos nucleicos por Reacción en Cadena de la Polimerasa. Los datos fueron agrupados y analizados por el Test Chi Cuadrado (χ2)y el Índice de Kappa (κ). Fue demostrada la alta prevalencia de la presencia del virus papiloma tanto en lengua (30 por ciento), como en tejidos periodontales (15 por ciento).
