OBJECTIVE: To compare the usefulness of MRI and PET/CT in nodal staging (N) of patients with locally advanced rectal cancer (LARC). MATERIAL AND METHODS: Retrospective study of patients with LARC, who completed their initial staging with PET/CT, between January-20 and March-23. Regional nodes were assessed, and N was determined using both techniques according to TNM criteria. Concordance between MRI and PET/CT was analyzed. The accuracy of both techniques was calculated for those patients who underwent direct surgery. Non-regional pelvic lymph nodes were evaluated by both modalities. RESULTS: Among the 73 patients, 48 were ultimately diagnosed with a locally advanced stage. Of these, 39 underwent neoadjuvant treatment (chemoradiotherapy) followed by surgery, and 9 direct surgery. In 25, the PET/CT extension study revealed distant disease, leading to systemic treatment. Weak concordance was observed between MRI and PET/CT in determining N (k=0.286; p<0.005). Out of 73 patients, 31(42%) exhibited concordance, and 42(58%) showed discordance. In 83% of the discordant cases, MRI overstaged compared to PET/CT, with 17 cases indicating nodal involvement (N+) by MRI and N0 by PET/CT. Diagnostic accuracy was 78% for both techniques. Sensitivity, specificity, positive predictive value, and negative predictive value were 80%, 75%, 80%, and 75% for MRI, and 60%, 100%, 100%, and 67%, for PET/CT. PET/CT identified pelvic metastatic adenopathies in 8 patients that were not visible/doubtful by MRI. CONCLUSIONS: In the initial nodal staging of rectal cancer MRI overstages relative to PET/CT. Both modalities are complementary, PET/CT offers higher specificity and MRI higher sensitivity.
PURPOSE: The aim of this study concerns the evaluation of peripapillary vessel indices in childhood glaucoma (CG) and healthy subjects. MATERIAL AND METHODS: In this prospective, unicenter, observational cross-sectional study, patients with CG and age and sex-matched healthy subjects were included. We compared retinal nerve fiber layer (RNFL) measurements in optical coherence tomography (OCT), peripapillary vessel density (PVD), and the flux index (FI) of the superficial vascular plexus from OCT angiography (OCT-A) between CG patients and control groups. RESULTS: We included 39 patients (68 eyes) with CG and 50 (95 eyes) healthy subjects. The peripapillary RNFL thickness, vessel density, and flux index were significantly lower in the CG group than in the control group. The mean PVD of CG patients was 0.52 ± 0.043%, compared with 0.55 ± 0.014%, p < 0.0001 in healthy subjects. The mean FI was 0.32 ± 0.054 versus 0.37 ± 0.028, p < 0.0001, in CG patients and healthy subjects, respectively. PVD and FI in the superior, inferior, and temporal sectors were significantly lower in CG. The peripapillary RNFL thickness showed a higher area under the ROC curve (AUROC) for discriminating healthy and CG eyes and was significantly different than the PVD (0.797, 95%CI 0.726-0.869; p < 0.0001 vs. 0.664, 95%CI 0.574-0.752; p 0.00037), p 0.012. CONCLUSIONS: PVD and FI show lower values in CG and correlate with RNFL thickness measurement but have lower diagnostic ability than RNFL thickness measurement. Our results reveal possible differences in the pathogenesis of microvascular compromise in childhood glaucoma patients.
Mexico is the third Latin American country with the most children and adolescents living with human immunodeficiency virus (ALHIV). There is a lack of information on the characteristics of this population. We aimed to describe the social and mental health characteristics of Mexican ALHIV. A census was conducted of all adolescent patients with HIV at a pediatric hospital (n = 47; mean age 14.39, S.D. = 3.65) and their caregivers. We collected data on socio-demographic characteristics, family, intelligence, mental health, adverse life events, substance use, treatment, knowledge of Antiretroviral Treatment (ART) and HIV, and biomarkers. Most cases were transmitted vertically and self-reported ART adherence was above 90%. Some obstacles to adherence were medicine discomfort, believing that they did not need it, and forgetfulness. The vulnerabilities were intellectual disability, adverse life events, possible mental health problems, and little knowledge of their illness and treatment. These findings suggest the importance of interventions to improve the perception and knowledge of HIV and ART to increase ART adherence.

Introducción: El miedo a la recaída es uno de los problemas psicológicos en los pacientes con cáncer, más específicos. El aumento en la esperanza de vida en el paciente oncológico, y la supervivencia, hace que cada vez más conozcamos las consecuencias emocionales, y vivir con el llamado Síndrome de la Espada de Damocles es sin duda una de las más importantes. Este miedo a la recaída puede llegar a ser invalidante y por ello cada vez más se elaboran programas terapéuticos para poderlo combatir. Uno de los más conocidos es el FORT (Fear of Recurrence Therapy) elaborado por Maheu y Lebel y que en este momento está siendo adaptado a otros lenguajes y culturas. Una de ellas es la adaptación de Gálvez en México. Objetivo: Nuestro objetivo en el presente trabajo preliminar es presentar los primeros datos de adaptación de esta terapia del español mexicano al europeo. Método: El procedimiento seguido es la validación ecológica propuesta por Bernal en base al consenso de dos psicooncólogas expertas. Resultados: Después de valorar el cambio de diferentes conceptos y terminologías, se han valorado de forma independiente por parte de ambas psicooncólogas, las 8 dimensiones de Bernal con un alto índice Kappa (de 0,8 a 1). Conclusiones: Este es un estudio preliminar al que le va a seguir los mismos pasos para el manual de la paciente por parte de profesionales y de pacientes con cáncer de mama (AU)
Introduction: Fear of recurrence is one of the most specific psychological problems faced by cancer patients. Their increase in life expectancy, and survival, makes them increasingly aware of the emotional consequences, and living with the so-called Sword of Damocles Syndrome is undoubtedly one of the most important. Fear of recurrence can become disabling and affect their emotional well-being, leading to the development of therapeutic programs like FORT (Fear of Recurrence Therapy) developed by Maheu and Lebel. This therapy is being adapted to different languages and cultures, including Mexican Spanish by Gálvez. Objective: In this preliminary work, we aim to present the first data on adapting FORT from Mexican Spanish to European Spanish. Methods: The procedure used was to follow the ecological validation method proposed by Bernal, by two skilled psychooncologists. Results: The assessment of different concepts and terminologies by the two psychooncologists in an independent way, the analysis yielded a high Kappa index (from 0.8 to 1) for the 8 dimensions of Bernal. Conclusions: This preliminary study will be followed by a similar process for the patient manual by professionals and breast cancer patients (AU)

Objetivo: evaluar las diferencias y relaciones por edad respecto al apoyo de pareja, ajuste diádico y calidad de vida relacionada con la salud (CVRS) entre los esposos de pacientes con cáncer de mama (CaMa). Método: estudio transversal-correlacional; participaron 120 esposos de pacientes con CaMa, divididos en dos grupos y basados en la edad de las pacientes: jóvenes (≤40) y mayores (≥50). Se aplicaron instrumentos validados en población mexicana de ajuste diádico, apoyo de pareja y CVRS en todos los participantes. Resultados: los esposos jóvenes reportaron menores niveles de ajuste diádico y menos apoyo por parte de su pareja y mejor CVRS, en comparación con esposos de mayores. Ajuste diádico y apoyo de pareja se asociaron positivamente en ambos grupos. En los esposos jóvenes el ajuste y el apoyo de pareja se relacionaron con dimensiones específicas de CVRS: salud en general, actividades sociales y salud mental. En los esposos mayores, se encontraron asociaciones entre ajuste diádico y un mayor número de dimensiones de CVRS; mientras que el apoyo de pareja que percibieron solo se relacionó con dos dimensiones de CVRS: actividades sociales y salud mental. Conclusiones: los esposos jóvenes perciben más dificultades dentro de su relación de pareja en comparación con los esposos mayores, y para estos últimos, el ajuste de su relación está asociada con más aspectos de su CVRS. Los resultados destacan la relevancia de diseñar y proporcionar intervenciones a la diada, con diferentes objetivos, considerando su edad (AU)
Objective: To evaluate the differences and relationships by age concerning couple support, dyadic adjustment, and health-related quality of life (HRQoL) of husbands of breast cancer patients. Methods: Cross-sectional correlational study; 120 spouses of breast cancer patients were recruited. The spouses were divided into two groups, based on patients age: ≤40, ≥50. Dyadic adjustment, couple support and HRQoL instruments were administered. All instruments were validated in the Mexican population. Results: Young spouses reported lower levels of dyadic adjustment and perceived fewer wives support, whereas older spouses had a better HRQoL. Both groups observed a positive association between dyadic adjustment and couple support. In younger spouses, adjustment and support were related to some dimensions of HRQoL: general health, social activities, and emotional aspects. In older spouses, more associations were found between dyadic adjustment and HRQoL. Support perceived by spouses was only related to social activities and mental health. Conclusions: Younger spouses perceive more difficulties within their relationship than older spouses. Additionally, their relationship adjustment is associated with more aspects of their HRQoL. The results highlight the relevance of designing and providing interventions to the dyad with different objectives depending on age (AU)

BACKGROUND: Optic nerve head (ONH) interpretation is a glaucoma screening method which may be influenced by criteria variability. Laguna ONhE software is a low-cost and non-invasive method of ONH analysis. METHODS: We analysed the results of the Laguna ONhE application, interpreting 552 ONH images from the ACRIMA database, publicly available on the Internet, and compared them with the opinion of five experts. Diagnostic agreement was investigated using Cohen's kappa (κ) with 95% confidence. RESULTS: The kappa concordance index obtained with Laguna ONhE and the majority of the experts' criterion (0.77) was significantly higher compared to that obtained with ACRIMA and the majority of the experts' criterion (0.61). In 44.7% of the cases there was absolute agreement among the 5 experts and the Laguna ONhE program. Removing borderline cases from the analysis yielded increased diagnostic agreement (0.81). The area under the receiver operating characteristic (AUROC) of the Laguna ONhE program (0.953, p < 0.001) was not significantly different than AUROC of the majority of the experts' criterion (0.925, p < 0.001), p = 0.052. Individually obtained expert's AUROCs were significantly lower (0.636 to 0.913; p < 0.01). CONCLUSIONS: Laguna ONhE's agreement with the experts is high, particularly where the diagnosis may be more obvious by the appearance of the ONH.
Mycetoma is one of the six Neglected Tropical Diseases that are prevalent in Turkana County (northwest Kenya). The aim of the study was to estimate the prevalence of mycetoma in the county, as well as to describe the main causative agents involved in the disease using methods affordable locally. Based on the data collected by the team of cooperative medicine Cirugia en Turkana (Surgery in Turkana), a specific study for mycetoma was started during the 16th humanitarian medicine campaign in February 2019. Patients with suspected mycetoma were studied at the Lodwar County Referral Hospital (LCRH). After informing the patient and getting their consent, the lesions were examined and sampled (mainly by biopsy) and clinical data were recorded. Samples were washed in sterile saline solution and cut in fragments. Some of these were inoculated on Sabouraud Dextrose Agar, Malt Extract Agar, and diluted Nutrient Agar plates. One fragment of each sample was used for DNA extraction. The DNA and the rest of the fragments of samples were kept at -20°C. All cultures were incubated at room temperature at the LCRH laboratory. The DNA obtained from clinical samples was submitted to PCR amplification of the ITS-5.8S and the V4-V5 16S rRNA gene region, for the detection and identification of fungi and bacteria respectively. From February 2019 till February 2022, 60 patients were studied. Most of them were men (43, 74,1%) between 13 and 78 y.o. (mean age 37). Half of the patients were herdsmen but, among women 40% (6) were housewives and 26.7% (4) charcoal burners. Lesions were mainly located at the feet (87.9%) and most of the patients (54; 93.1%) reported discharge of grains in the exudate, being 27 (46.6%) yellow or pale colored and 19 (32.8%) of them dark grains. Culture of clinical samples yielded 35 fungal and bacterial putative causative agents. Culture and molecular methods allowed the identification of a total of 21 causative agents of mycetoma (39.6% of cases studied). Most of them (17) corresponded to fungi causing eumycetoma (80.9%) being the most prevalent the genus Madurella (7; 41.2%), with two species involved (M. mycetomatis and M. fahalii), followed by Aspergillus (2; 11.8%). Other minority genera detected were Cladosporium, Fusarium, Acremonium, Penicillium, and Trichophyton (5.9% each of them). Actinobacteria were detected in 19.1% of samples, but only Streptomyces somaliensis was identified as a known agent of mycetoma, the rest being actinobacteria not previously described as causative agents of the disease, such as Cellulosimicrobium cellulans detected in two of the patients. Although Kenya is geographically located in the mycetoma belt, to our knowledge this is the first report on mycetoma in this country from 1973, and the first one for Turkana County.

Microneedle Array Patches (MAPs) are an emerging dosage form that creates transient micron-sized disruptions in the outermost physical skin barrier, the stratum corneum, to facilitate delivery of active pharmaceutical ingredients to the underlying tissue. Numerous MAP products are proposed and there is significant clinical potential in priority areas such as vaccination. However, since their inception scientists have hypothesized about the risk of a clinically significant MAP-induced infection. Safety data from two major Phase 3 clinical trials involving hundreds of participants, who in total received tens of thousands of MAP applications, does not identify any clinically significant infections. However, the incumbent data set is not extensive enough to make definitive generalizable conclusions. A comprehensive assessment of the infection risk is therefore advised for MAP products, and this should be informed by clinical and pre-clinical data, theoretical analysis and informed opinions. In this article, a group of key stakeholders identify some of the key product- and patient-specific factors that may contribute to the risk of infection from a MAP product and provide expert opinions in the context of guidance from regulatory authorities. Considerations that are particularly pertinent to the MAP dosage form include the specifications of the finished product (e.g. microbial specification), it's design features, the setting for administration, the skill of the administrator, the anatomical application site, the target population and the clinical context. These factors, and others discussed in this article, provide a platform for the development of MAP risk assessments and a stimulus for early and open dialogue between developers, regulatory authorities and other key stakeholders, to expedite and promote development of safe and effective MAP products.

Cytogenetic assessment in myelofibrosis is essential for risk stratification and patient management. However, an informative karyotype is unavailable in a significant proportion of patients. Optical genome mapping (OGM) is a promising technique that allows for a high-resolution assessment of chromosomal aberrations (structural variants, copy number variants, and loss of heterozygosity) in a single workflow. In this study, peripheral blood samples from a series of 21 myelofibrosis patients were analyzed via OGM. We assessed the clinical impact of the application of OGM for disease risk stratification using the DIPSS-plus, GIPSS, and MIPSS70+v2 prognostic scores compared with the standard-of-care approach. OGM, in combination with NGS, allowed for risk classification in all cases, compared to only 52% when conventional techniques were used. Cases with unsuccessful karyotypes (n = 10) using conventional techniques were fully characterized using OGM. In total, 19 additional cryptic aberrations were identified in 9 out of 21 patients (43%). No alterations were found via OGM in 4/21 patients with previously normal karyotypes. OGM upgraded the risk category for three patients with available karyotypes. This is the first study using OGM in myelofibrosis. Our data support that OGM is a valuable tool that can greatly contribute to improve disease risk stratification in myelofibrosis patients.
INTRODUCTION: Most of the pregnant women do not achieve the recommended dietary intake of vitamins A and E. These vitamins may counteract oxidative stress involved in some adverse perinatal outcomes. We aimed to assess the associations between maternal vitamin A and E at mid-pregnancy with both maternal and fetal outcomes and to identify possible early biomarkers during pregnancy to predict and prevent oxidative stress in the offspring. METHODS: Data on dietary and serum levels of vitamins A and E were collected from 544 pregnant women from the Nutrition in Early Life and Asthma (NELA) study, a prospective mother-child cohort set up in Spain. RESULTS: There were large discrepancies between low dietary vitamin E intake (78% of the mothers) and low serum vitamin E levels (3%) at 24 weeks of gestation. Maternal serum vitamins A and E at mid-pregnancy were associated with higher antioxidant status not only in the mother at this time point (lower hydroperoxides and higher total antioxidant activity [TAA]) but also with the newborn at birth (higher TAA). Gestational diabetes mellitus (GDM) was negatively associated with maternal serum vitamin A (OR: 0.95 CI: 0.91-0.99, p = 0.009) at mid-pregnancy. Nevertheless, we could not detect any association between GDM and oxidative stress parameters. CONCLUSIONS: In conclusion, maternal vitamin A and E serum levels may be used as an early potential biomarker of antioxidant status of the neonate at birth. Control of these vitamins during pregnancy could help avoid morbid conditions in the newborn caused by oxidative stress in GDM pregnancies.

La pandemia por COVID-19 resultó un problema para la salud pública mundial, que impactó particularmente al sector de trabajadores que debían trabajar y estar expuestos durante el periodo de cuarentena. Objetivo, analizar la incidencia de COVID-19 y sus características en trabajadores(as) activos(as) durante 34 semanas. Investigación descriptiva y transversal. Población constituida por todos los trabajadores(as) activos de sectores priorizados, con diagnóstico confirmado de COVID-19. De los 1.186 casos confirmados, 658 casos (55%) correspondió a trabajadores activos, una incidencia de 1,7 casos x 1000 (mayor a la esperada), con predominio en trabajadores(as) del sector salud (267casos), choferes del transporte y trabajadores de funerarias (253 casos). El 68,7% menor de 40 años y predominio del sexo masculino (61,2%). En el personal de salud, el 30% correspondió a personal de enfermería y 22% en médicos. La tasa de mortalidad en la población de trabajadores activos fue de 0,07 x cada 1000, con un índice de mortalidad de 0,05 y un índice de recuperación del 95,5%, comportamiento similar al de la población general. Sin embargo, la tasa de letalidad (trabajadores activos positivos fallecidos) fue del 4,4% (29 casos), donde el 75% (22/29) fueron enfermeras y médicos, lo que confirmó al sector salud y trabajadores(as) de servicios, como población trabajadora altamente expuesta y vulnerable, lo que justificó priorizar las medidas de prevención en estos trabajadores, al iniciar el sistema de vigilancia epidemiológica, la vacunación y la dotación con uso adecuado de la protección personal(AU)
The COVID-19 Pandemic was a problem for global public health, which particularly impacted the sector of workers who had to work and were exposed during the quarantine period. The objective was to analyze the incidence of COVID- 19 and its characteristics in active workers during 34 weeks. Descriptive and cross-sectional research. Population made up of all active workers in prioritized sectors, with a confirmed diagnosis of COVID-19. Of the 1,186 confirmed cases, 658 cases (55%) corresponded to active workers, an incidence of 1.7 cases per 1,000 (higher than expected), with a predominance of workers in the health sector (267 cases), transport drivers and funeral home workers (253 cases). 68.7% under 40 years of age and predominance of the male sex (61.2%). In health personnel, 30% corresponded to nursing personnel and 22% to doctors. The mortality rate in the population of active workers was 0.07 x every 1000, with a mortality rate of 0.05 and a recovery rate of 95.5%, behavior similar to that of the general population. However, the fatality rate (deceased positive active workers) was 4.4% (29 cases), where 75% (22/29) were nurses and doctors, which confirmed the health sector and service workers, as a highly exposed and vulnerable working population, which justified prioritizing prevention measures in these workers, by initiating the epidemiological surveillance system, vaccination and provision with adequate use of personal protection(AU)

PRCIS: Childhood glaucoma produces alterations in the postnatal development and function of various ocular structures, including the cornea. Childhood glaucoma patients present lower corneal transplant survival rates. Our series shows outcomes of corneal transplant in childhood glaucoma with survival rates of 29% at 2 years. OBJECTIVE: To investigate the surgical outcome of different types of keratoplasty in eyes with childhood glaucoma. PATIENTS AND METHODS: A retrospective review was made of the medical records from 17 eyes of 15 patients who were diagnosed with childhood glaucoma and received a corneal transplantation between January 2010 and July 2020. Patient demographics, intraocular pressure, previous ocular surgery, comorbidities, corneal transplant surgery, and follow-up outcome were collected. The primary efficacy endpoint was graft survival (in months) until failure, the latter being considered as irreversible loss of corneal transparency. Secondary efficacy points were the need for an increase in topical hypotensive therapy and the need for additional surgery. RESULTS: Seventeen eyes of 15 patients were included, 11 eyes (10 patients) with primary congenital glaucoma and 6 with other types of childhood glaucoma. Corneal transplantation was performed at the mean age of 23.76 ± 14.86 years. At the time of the transplantation, the number of topical medications was 1.35 ± 1.27, intraocular pressure was 15.00 ± 8.34 mm Hg, and patients had received up to 7 glaucoma surgeries. Descemet stripping automated endothelial keratoplasty was performed in 13 eyes (76%) and penetrating keratoplasty in 4 (24%). After surgery, 7 (41%) eyes required increased topical treatment and 2 (12%) glaucoma surgery. Twelve eyes (71%) developed graft failure at 24 months, the mean time of survival being 13.88 ± 8.25 months. CONCLUSIONS: Management of corneal decompensation in childhood glaucoma poses a challenge. In this series of childhood glaucoma with corneal transplantations, the survival rate was 29% at 24 months.
BACKGROUND: We assessed the relationship of estimated glomerular filtration rate values at hospital admission on the outcome of surgically treated older adults who had suffered a hip fracture. METHODS: Prospective study that included patients > 65 years of age, surgically treated for primary hip fracture, with no pathologic or high-energy trauma aetiology admitted to a tertiary teaching hospital between 2018 and 2019. We stratified patients based on their estimated glomerular filtration rate at admission and examined its association to demographic and clinical variables, including 90-day post-discharge mortality. RESULTS: The study included 942 hip fracture patients. Lowered estimated glomerular filtration rate was significantly associated to a worsening of the functional status, higher incidence of medical postoperative complications, higher postoperative renal dysfunction, and greater number of blood transfusions. Mortality displayed a staircase pattern, increasing with decreasing estimated glomerular filtration rate. Patients with estimated glomerular filtration rate <60 had significantly higher mortality at 90 days after discharge. In-hospital mortality rate was 10.7% in hip fracture patients with chronic kidney disease who experienced a significant variation in the estimated glomerular filtration rate (>5 mL/min/1.73m2) on admission in comparison to baseline values. CONCLUSION: Older adult patients treated for hip fracture with lower glomerular filtration rate values have poorer functional status and worse prognosis. A significant clinical variation of estimated glomerular filtration rate upon hospital admission for hip fracture may be associated with increased in-hospital mortality of chronic kidney disease patients.

Human ß-defensin 1 (hBD-1) is a constitutively expressed antimicrobial peptide with antiviral properties. CMV seropositivity has been associated with obesity. It is unknown if hBD-1 levels of are altered in women with obesity and/or CMV seropositivity. In a pilot project of 31 adult women with CMV seropositivity, we calculated the correlation among hBD-1 serum levels (ELISA) and IgG anti-CMV-Index with anthropometric measurements, lipid profiles and glucose levels. hBD-1 showed negative correlation with triglycerides (TG) (r = -0.617; p = 0.033,) and hip circumference (r = -0.596; p = 0.041,). IgG anti-CMV index was negatively correlated with hBD-1 levels and positively correlated with TG (r = 0.702; p = 0.011,) and HC (r = 0.583; p = 0.047,) in women with obesity. As expected, hBD-1 levels correlates with IFN-γ (an antimicrobial peptide elicitor) in the three analyzed groups.These results shows that CMV seropositivity correlates with both IFN-γ levels and hBD-1 levels which in contrast with non-CMV seropositivity scenario, is commonly found an IFN-γ upregulation in individuals with obesity. Further research is encouraged to test if CMV is causing the observed downregulation of the antiviral immune responses of both hBD-1 and IFN-γ as well as their involved mechanisms.

Fundamento: Evaluar la influencia de los valores de filtrado glomerular estimado (eFG) al ingreso en el pronóstico de los pacientes mayores con fractura de cadera tratados quirúrgicamente.Métodos: Estudio prospectivo de pacientes >65 años, tratados quirúrgicamente por una fractura de cadera primaria, sin etiología tumoral o traumatismo de alta energía, en un hospital universitario terciario entre 2018 y 2019. Estratificamos a los pacientes según el FG al ingreso y estudiamos su asociación con distintas variables demográficas y clínicas, incluida la mortalidad hasta 90 días después del alta hospitalaria.Resultados: Se incluyeron 942 pacientes. La disminución del eFG se asoció significativamente a peor estado funcional, mayor incidencia de complicaciones médicas postoperatorias, mayor disfunción renal postoperatoria y mayor necesidad de transfusión sanguínea. La mortalidad mostró un patrón en escalera que aumentaba con la disminución del eFG. A los 90 días, la mortalidad fue significativamente mayor en pacientes con eFG <60. Los pacientes con enfermedad renal crónica que sufrían una fractura de cadera y experimentan al ingreso una variación significativa del eFG (>5 mL/min/1,73m2) respecto a los valores basales mostraron una tasa de mortalidad intrahospitalaria del 10,7%.Conclusiones: Los pacientes ancianos tratados quirúrgicamente por fractura de cadera con valores más bajos de tasa de eFG presentan peor estado funcional y peor pronóstico. Una variación clínica significativa del FG (>5) en el momento del ingreso hospitalario tras una fractura de cadera podría asociarse a un aumento de la mortalidad intrahospitalaria de los pacientes con insuficiencia renal crónica.(AU)
Background: We assessed the relationship of estimated glomerular filtration rate values at hospital admission on the outcome of surgically treated older adults who had suffered a hip fracture. Methods: Prospective study that included patients > 65 years of age, surgically treated for primary hip fracture, with no pathologic or high-energy trauma aetiology admitted to a tertiary teaching hospital between 2018 and 2019. We stratified patients based on their estimated glomerular filtration rate at admission and examined its association to demographic and clinical variables, including 90-day post-discharge mortality. Results: The study included 942 hip fracture patients. Lowered estimated glomerular filtration rate was significantly associated to a worsening of the functional status, higher incidence of medical postoperative complications, higher postoperative renal dysfunction, and greater number of blood transfusions. Mortality displayed a staircase pattern, increasing with decreasing estimated glomerular filtration rate. Patients with estimated glomerular filtration rate <60 had significantly higher mortality at 90 days after discharge. In-hospital mortality rate was 10.7% in hip fracture patients with chronic kidney disease who experienced a significant variation in the estimated glomerular filtration rate (>5 mL/min/1.73m2 ) on admission in comparison to baseline values. Conclusion: Older adult patients treated for hip fracture with lower glomerular filtration rate values have poorer functional status and worse prognosis. A significant clinical variation of estimated glomerular filtration rate upon hospital admission for hip fracture may be associated with increased in-hospital mortality of chronic kidney disease patients.(AU)

PURPOSE: To assess the presence of macular intervortex venous anastomosis in central serous chorioretinopathy (CSCR) patients using en face optical coherence tomography (EF-OCT). METHODS: A cross-sectional study where EF-OCT 6 × 6 and 12 × 12 mm macular scans of patients with unilateral chronic CSCR were evaluated for anastomosis between vortex vein systems in the central macula. The presence of prominent anastomoses was defined as a connection with a diameter ≥150 µm between the inferotemporal and superotemporal vortex vein systems which crossed the temporal raphe. Three groups were studied: CSCR eyes (with an active disease with the presence of neurosensorial detachment; n = 135), fellow unaffected eyes (n = 135), and healthy eyes as controls (n = 110). Asymmetries, abrupt termination, sausaging, bulbosities and corkscrew appearance were also assessed. RESULTS: In 79.2% of the CSCR eyes there were prominent anastomoses in the central macula between the inferotemporal and superotemporal vortex vein systems, being more frequent than in fellow eyes and controls (51.8% and 58.2% respectively). The number of anastomotic connections was higher in the affected eye group (2.9 ± 1.8) than in the unaffected fellow eye group (2.1 ± 1.7) and the controls (1.5 ± 1.6) (p < 0.001). Asymmetry, abrupt terminations and the corkscrew appearance of the choroidal vessels were more frequent in the affected eyes, although no differences in sausaging or bulbosities were observed. CONCLUSIONS: Intervortex venous anastomoses in the macula were common in CSCR, being more frequently observed in affected eyes than in fellow unaffected eyes and healthy controls. This anatomical variation could have important implications concerning the pathogenesis and classification of the disease.
BACKGROUND/AIMS: Vascular factors are involved in the development of glaucoma, including diseases such as hypercholesterolemia (HC), systemic arterial hypertension (SAH), and diabetes mellitus (DM). The aim of this study was to determine the effect of glaucoma disease on peripapillary vessel density (sPVD) and macular vessel density (sMVD) on the superficial vascular plexus, controlling differences on comorbidities such as SAH, DM and HC between glaucoma patients and normal subjects. METHODS: In this prospective, unicenter, observational cross-sectional study, sPVD and sMVD were measured in 155 glaucoma patients and 162 normal subjects. Differences between normal subjects and glaucoma patients' groups were analyzed. A linear regression model with 95% confidence and 80% statistical power was performed. RESULTS: Parameters with greater effect on sPVD were glaucoma diagnosis, gender, pseudophakia and DM. Glaucoma patients had a sPVD 1.2% lower than healthy subjects (Beta slope 1.228; 95%CI 0.798-1.659, p < 0.0001). Women presented 1.19% more sPVD than men (Beta slope 1.190; 95%CI 0.750-1.631, p < 0.0001), and phakic patients presented 1.7% more sPVD than men (Beta slope 1.795; 95%CI 1.311-2.280, p < 0.0001). Furthermore, DM patients had 0.9% lower sPVD than non-diabetic patients (Beta slope 0.925; 95%CI 0.293-1.558, p = 0.004). SAH and HC did not affect most of the sPVD parameters. Patients with SAH and HC showed 1.5% lower sMVD in the outer circle than subjects without those comorbidities (Beta slope 1.513; 95%CI 0.216-2.858, p = 0.021 and 1.549; 95%CI 0.240-2.858, p = 0.022 respectively. CONCLUSIONS: Glaucoma diagnosis, previous cataract surgery, age and gender seem to have greater influence than the presence of SAH, DM and HC on sPVD and sMVD, particularly sPVD.
