Estudio de prevalencia, conocimiento y control de la hipertensión arterial en barrios vulnerables de Argentina / Prevalence, knowledge and control of arterial hypertension in vulnerable neighborhoods of Argentina: A Cross-sectional Study

Introducción: La hipertensión arterial (HTA) representa el principal factor de riesgo individual, con mayor carga a nivel mundial de enfermedades cardiovasculares (ECV). En nuestro país, algunos trabajos epidemiológicos han mostrado marcadas diferencias en las prevalencias de estos factores de riesgo de acuerdo con la población evaluada. Sin embargo, no hay estudios epidemiológicos de evaluación de factores de riesgo cardiovascular exclusivos referentes a barrios vulnerables con muy bajos recursos económicos, socioculturales y poca accesibilidad a los sistemas de salud. Materiales y métodos: Estudio observacional de corte transversal multicéntrico en habitantes de comunas vulnerables de muy bajos recursos, como asentamientos populares y barrios carenciados con muestreo aleatorizado simple de casas. Se realizaron tomas de presión arterial (PA), medidas antropométricas, así como cuestionarios epidemiológicos, económicos y socioculturales. Se describen los hallazgos: prevalencia, conocimiento y control de la PA en las distintas regiones. Se efectuó una regresión logística para determinar las variables independientes a los resultados principales. Resultados: Se analizaron 989 participantes. La prevalencia de HTA global fue de 48,2%. Un total de 82% tenía un índice de masa corporal (IMC) >25 kg/m2. De estos pacientes, 45,3% tenían menos de seis años de educación. Este último aspecto se asoció a mayor prevalencia de HTA de forma independiente. De los hipertensos, 44% desconocían su padecimiento y solo en 17,2% estaba controlado, asociándose esto a tener obra social (OS) y mayor nivel educativo. Únicamente 24% estaban bajo tratamiento combinado. Conclusión: La prevalencia de HTA en barrios vulnerables es elevada, superando a la de otros estratos sociales con niveles de conocimiento, tratamiento y control de la HTA bajos, similar a otras poblaciones. Se detectó un uso insuficiente de la terapia combinada.

Introduction: Hypertension (HTN) represents the primary individual risk factor, contributing significantly to the global burden of cardiovascular diseases (CVD). In our country, epidemiological research has highlighted substantial variations in the prevalence of these risk factors across different populations. However, there is a lack of epidemiological studies assessing exclusive cardiovascular risk factors within vulnerable neighborhoods characterized by extremely limited economic resources, sociocultural challenges, and inadequate healthcare access. Methods: A multicenter cross-sectional observational study was conducted among individuals residing in economically deprived and marginalized communities, including informal settlements and underprivileged neighborhoods. Simple random sampling of households was employed. Blood pressure measurements, anthropometric assessments, and epidemiological, economic, and sociocultural questionnaires were administered. Results encompass prevalence rates, awareness levels, and blood pressure control across diverse regions. Logistic regression was utilized to identify independent variables influencing primary outcomes. Results: A total of 989 participants were analyzed. The overall prevalence of hypertension was 48.2%. About 82% had a body mass index (BMI) >25. Approximately 45.3% had less than 6 years of formal education. Independent association was established between education levels below 6 years and higher hypertension prevalence Among hypertensive individuals, 44% were unaware of their condition, with only 17.2% achieving control, correlated with having health insurance and a higher educational background. Merely 24% were receiving combined therapy. Conclusion: The prevalence of hypertension within vulnerable neighborhoods is alarmingly high, surpassing rates in other social strata. Knowledge, treatment, and control levels of hypertension are suboptimal, comparable to other populations... (AU)

Can the Dose of Belimumab be Reduced in Patients with Systemic Lupus Erythematosus?

OBJECTIVES: The aims of this study were to investigate the prevalence of dose reduction in patients with SLE treated with belimumab (BEL) in Spain, analyze treatment modalities, and determine impact on control of disease activity. METHODS: Retrospective longitudinal and multicentre study of SLE patients treated with BEL. Data on disease activity, treatments and outcomes were recorded before and after reduction (6-12 months), and they were compared. RESULTS: A total of 324 patients were included. The dose was reduced in 29 patients (8.9%). The dosing interval was increased in 9 patients receiving subcutaneous BEL and in 6 patients receiving intravenous BEL. The dose per administration was reduced in 16 patients.Pre-reduction status was remission (2021 DORIS) in 15/26 patients (57.7%) and LLDAS in 23/26 patients (88.5%). After reduction, 2/24 patients (8.3%) and 3/22 patients (13.6%) lost remission at 6 months and 12 months, respectively (not statistically significant [NS]). As for LLDAS, 2/23 patients (8.7%) and 2/21 patients (9.5%) lost their status at 6 and 12 months, respectively (NS). Significantly fewer patients were taking glucocorticoids (GCs) at their 12-month visit, although the median dose of GCs was higher at the 12-month visit (5 [0.62-8.75] vs 2.5 [0-5] at baseline). CONCLUSION: Doses of BEL can be reduced with no relevant changes in disease activity-at least in the short term-in a significant percentage of patients, and most maintain the reduced dose. However, increased clinical or serologic activity may be observed in some patients. Consequently, tighter post-reduction follow-up is advisable.

Calidad de vida en pacientes con tumor vesical no músculo-invasivo sometidos a tratamiento adyuvante intravesical / Quality of life in patients with non-muscle invasive bladder tumor undergoing adjuvant intravesical treatment

Introducción El objetivo del estudio fue establecer posible relación entre los tratamientos con mitomicina-C (MMC) y bacilo de Calmette-Guérin (BCG) y la afectación en la calidad de vida. Material y métodos Estudio cuasiexperimental, prospectivo y longitudinal, recogiendo pacientes sometidos a tratamiento adyuvante en TVNMI. Se utilizaron los cuestionarios Short form-12 (SF-12) y Urogenital Distress Inventory-6 (UDI-6) para medir la calidad de vida. Se compararon las puntuaciones de los cuestionarios entre casos con MMC y BCG antes de iniciar la inducción (M1), a las 4 semanas (M2) y a los dos meses (M3). Resultados Se recogieron 90 pacientes, 54 en el grupo de BCG y 36 en el de MMC. Se comprobó que los pacientes con BCG percibían peor calidad de vida física comparados con los de MMC en M2 (OR:2,59, p=0,046). Además, se hallaron cambios significativos en la calidad de vida urinaria de los pacientes en tratamiento con MMC entre los diferentes momentos temporales (puntuación del UDI-6: 33,33 en M1, 27,78 en M2 y 16,67 en M3, p=0,001). Conclusiones No existen diferencias en la calidad de vida urinaria entre los pacientes tratados con MMC y BCG. Los pacientes con MMC muestran una recuperación significativa de la calidad de vida urinaria a partir de la finalización de la inducción, que aumenta aún más a los dos meses de la misma. Además, los pacientes tratados con BCG presentan peor calidad de vida física a las 4 semanas de tratamiento que aquellos tratados con MMC (AU)

Introduction The objective of the study was to establish a possible relationship between mitomycin-C (MMC) and bacillus Calmette-Guérin (BCG) treatments and quality of life impairment. Material and methods Quasi-experimental, prospective, and longitudinal study including patients undergoing adjuvant treatment in NMIBC. The Short form-12 (SF-12) and Urogenital Distress Inventory-6 (UDI-6) questionnaires were used to measure quality of life. Questionnaire scores were compared between cases with MMC and BCG before induction (M1), at 4 weeks (M2) and at 2 months (M3). Results Of the 90 patients enrolled, 54 were in the BCG group and 36 in the MMC group. It was found that BCG patients had worse perceived physical quality of life compared to MMC patients in M2 (OR:2.59, p=0.046). In addition, significant changes were found in the urinary quality of life of patients on MMC treatment between the different time points (UDI-6 score: 33.33 in M1, 27.78 in M2 and 16.67 in M3, p=0.001). Conclusions There are no differences in urinary quality of life between patients treated with MMC and BCG. Patients with MMC show a significant recovery of urinary quality of life from the completion of the induction course, which becomes even more significant after 2 months. In addition, BCG-treated patients have worse physical quality of life after 4 weeks of treatment than those treated with MMC (AU)

Women in urology: what is their current situation in Spain?

OBJECTIVE: To analyze the current state of women in urology in Spain. MATERIAL AND METHODS: Descriptive study based on the results of an online survey sent between February and April 2020 through the database of the Residents and Young Urologists group (RAEU) of the Spanish Association of Urology (AEU). Characteristics of the survey and its results were analyzed. RESULTS: In total, 257 responses were obtained from 210 women (81.71%) and 47 men (18.29%) belonging to 111 hospitals. Statistically significant differences were observed (p < 0.001) with a higher proportion of men in all categories except for the group of young female and male attendings (29-39 years, p = 0.789), and the group of female residents against male residents (p = 0.814). The number of men was higher in hospitals with subspecialty units except for the Pelvic Floor Unit, where no statistically significant difference was observed (p = 0.06). Regarding positions of responsibility, only 7 out of 111 hospitals had female Department Chiefs. CONCLUSIONS: Women's representation in urology is increasing, mainly due to the younger generations. However, the access of these women to relevant positions is anecdotal.

Role of PI3K, ERK1/2, and JAK2 Kinases in the Cardioprotective Effect of Deltorphin II during Cardiac Reperfusion.

The signaling mechanism of the cardioprotective effect of deltorphin II was studied in models of coronary occlusion (45 min) and reperfusion (120 min) in male Wistar rats. We used the selective δ2-opioid receptor agonist deltorphin II (0.12 mg/kg), which was administered intravenously 5 min before reperfusion, the PI3K inhibitor wortmannin (0.025 mg/kg), the ERK1/2 blocker PD-098059 (0.5 mg/kg), the inhibitor JAK2 AG490 (3 mg/kg). All kinase blockers were administered 10 min before reperfusion. The infarct-limiting effect of deltorphin II is associated with the activation of PI3K and ERK1/2 and does not depend on JAK2.

The Role of NO Synthase, MPT pore, and Protein Kinase A in the Cardioprotective Effect of the Opioid Receptor Agonist Deltorphin II.

In male Wistar rats, coronary occlusion (45 min) and reperfusion (120 min) were modeled. Selective δ2-opioid receptor agonist (deltorphin II, 0.12 mg/kg) was administered intravenously 5 min before reperfusion; NO synthase inhibitor (L-NAME, 10 mg/kg), MPT pore blocker (atractyloside, 5 mg/kg), and protein kinase A inhibitor (H-89, 10 µg/kg) were administered intravenously 10 min before reperfusion. Deltorphin II administered before reperfusion led to a 2-fold decrease in the infarct size. The infarct-limiting effect of deltorphin II was associated with blockade of MPT pore. Protein kinase A and NO synthase were not involved in the cardioprotective effect of deltorphin II.

Bilateral extensor digitorum brevis manus. / Extensor digitorum brevis manus bilateral.

INTRODUCTION: The extensor digitorum brevis manus (EDBM) is an accessory muscle of the dorsum of the hand that may appear as a painful mass. It is treated surgically, usually by excision of the muscle. CASE REPORT: 14-year-old male with bilateral painful masses on the dorsal aspect of his hands. Ultrasound confirmed the diagnosis of EDBM. Due to the associated symptoms, decision was made to conduct surgical treatment with resection of both muscle masses. DISCUSSION: EDBM is an infrequent cause of wrist pain, especially in children and adolescents. Surgical treatment has proven to have a significant impact on the improvement of the symptoms suffered by these patients.

Intravascular papillary endotelial hiperplasia, the unusual diagnosis of an orbital mass.

Intravascular papillary endotelial hyperplasia is a bening vascular lesion that rarely involves the periocular region, nevertheless, it should be considered in the differential diagnosis of a periorbital mass. It is histopatologically characterized by intravascular fibrous papillary fronds covered by endothelial cells. Histopathological differentiation from angiosarcoma can be challenging but is very important to avoid aggressive treatments. Complete surgical excision is frequently curative. Uncompleted excision can lead to recurrences. We describe the clinical and histological findings of intravascular papillary endotelial hyperplasia in the left lower lid of a 72-year-old woman who had a painless mass since 15 years ago, that caused hypertropia of her left eye. Histopathological examination revealed intralesional calcification, which is not an usual feature in this entity. The patient underwent complete surgical resection of the mass and there was no evidence of recurrence after 5 months of follow-up after surgery.

Hiperplasia endotelial papilar intravascular, el inusual diagnóstico de una masa orbitaria / Intravascular papillary endotelial hiperplasia, the unusual diagnosis of an orbital mass

La hiperplasia endotelial papilar intravascular es una lesión vascular benigna, infrecuente en la región periocular, pero que debe ser tenida en cuenta en el diagnóstico diferencial de una masa periorbitaria.Histopatológicamente se caracteriza por la proliferación intravascular de proyecciones papilares de tejido conectivo recubiertas por células endoteliales. La diferenciación anatomopatológica con el angiosarcoma puede ser difícil, pero es muy importante para evitar tratamientos agresivos. Generalmente, la escisión quirúrgica completa es curativa, mientras que una escisión incompleta puede causar recurrencias.Describimos un caso clínico de hiperplasia endotelial papilar intravascular en una mujer de 72 años que presentaba una masa palpebral inferior izquierda de 15 años de evolución que le provocaba hiperglobo del ojo izquierdo. El estudio histopatológico mostró la presencia de calcificación intralesional, característica infrecuente en esta patología.La masa fue extirpada completamente y tras 5 meses de seguimiento no mostró signos de recurrencia.

Diagnostic approach to small-bowel wall thickening: Beyond Crohn's disease and cancer.

Although small-bowel wall thickening is a common manifestation of Crohn's disease and tumors, many other entities can give rise to similar imaging findings. The small bowel is difficult to access by endoscopy, so radiologic imaging tests play an essential role in the diagnosis of conditions involving the small bowel. The main objectives of this paper are to explain the definition of small-bowel wall thickening, analyze the patterns of involvement seen in multidetector computed tomography (MDCT) with intravenous contrast administration, and provide an image-based review of the different causes of small-bowel wall thickening. The differential diagnosis must include many entities because wall thickening can result from immune-mediated, infectious, or vascular causes, as well as from toxicity and other lesser-known entities. As the imaging appearance of many of these conditions overlap, clinical and laboratory findings are necessary to support the imaging diagnosis.

A bibliometric study of the journal Radiología during the period 2010-2019. / Análisis bibliométrico de la revista Radiología en el periodo 2010-2019.

BACKGROUND AND AIMS: Bibliometrics makes it possible to measure the relative importance of a scientific journal in its field. The current study analyzed the scientific publications in Radiología and the bibliometric parameters of the journal in the period comprising 2010 through 2019. MATERIALS AND METHODS: We reviewed the bibliometrics for Radiología through information obtained from three sources: Scopus, the online version of the journal, and the publisher (Elsevier). We retrospectively analyzed aspects related to the editorial process (final decision and speed), the articles published (type, subspecialty of radiology, and imaging technique), the trends in citation and various indices (CiteScore, SNIP, and SJR), visibility, downloads, author characteristics (geographical origin and institutional collaboration), and the most cited articles. RESULTS: The number of articles published in Radiología gradually decreased during the decade, and the time to publication increased. Original research articles account for the largest share of the articles published. The most common subject areas were radiology of the digestive tract and neuroradiology. Nevertheless, the bibliometric indicators and the number of downloads of articles increased every year. Regarding the authorship of the articles published, although authors from Spain predominate, the participation of authors from other countries became increasingly common. Collaboration among different institutions also became increasingly common in the period analyzed. CONCLUSIONS: This review shows the progression of the journal's scientific work and some aspects that must be addressed to favor the growth of Radiología.

Ecografía de los cuerpos extraños subcutáneos: diferencias según naturaleza, complicaciones y potenciales errores diagnósticos / Ultrasonography of subcutaneous foreign bodies: differences depending on their nature, complications, and potential diagnostic errors

Los pacientes con heridas penetrantes y sospecha de cuerpos extraños retenidos representan un motivo frecuente de consulta en los servicios de urgencias. Es necesario un estudio radiográfico para descartar la presencia de cuerpos extraños. Sin embargo, las radiografías solo resultan de utilidad en los objetos radiopacos (metal, vidrio, piedra y algunos plásticos). Cuando la sospecha diagnóstica es alta y el estudio radiográfico es negativo, es necesario realizar otras pruebas de imagen. La ecografía ha demostrado su utilidad en la identificación y localización de cuerpos extraños tanto radiopacos como radiotransparentes. La ecografía permite una excelente evaluación de las estructuras adyacentes (músculos, tendones, ligamentos y estructuras neurovasculares) y ha demostrado ser de utilidad en la valoración de sus lesiones asociadas. Los diferentes materiales de los cuerpos extraños presentan patrones ecográficos característicos que resultan de utilidad para su aproximación diagnóstica. Por último, es importante estar familiarizado con los potenciales errores diagnósticos para evitar falsos positivos

Patients with penetrating wounds with suspected foreign bodies retained in the wound are often seen in emergency departments. Imaging studies are necessary to rule out the presence of retained foreign bodies. Plain-film X-rays, however, are only useful when the foreign bodies contain radiopaque material (metal, glass, stone, and some plastics). In cases with strong diagnostic suspicion and negative plain films, other imaging tests are necessary. Ultrasonography has proven useful in the identification and location of both radiopaque and radiotransparent foreign bodies. Ultrasonography enables excellent assessment of adjacent anatomical structures (muscles, tendons, ligaments, and neurovascular structures) and of associated lesions. The different materials found in foreign bodies have characteristic ultrasonographic patterns that are useful for diagnosis. Finally, it is important to be familiar with the diagnostic pitfalls to avoid false positives
