RESUMEN

BACKGROUND: To reduce health inequities in paediatric patients with complex diseases, our hospital developed a food security programme in 2022. The programme aims to mitigate food insecurity (FI) in paediatric patients with oncological, transplantation and congenital cardiovascular diagnoses, by providing a monthly nutritious food supply that covers up to 50% of the patient's family food intake, accompanied by social and nutritional follow-up. In this study, we aimed to assess the effect of the programme on FI and nutritional status and describe its implementation. METHOD: We conducted a before-and-after study of patients who entered the programme in a 14-month period. We used the Escala Latinoamericana y Caribeña de Seguridad Alimentaria (ELCSA) scale score, FI level and nutritional status measures to assess the effect of the programme. We used the Wilcoxon and McNemar tests to assess changes in scores and proportions of patients with moderate and severe FI, respectively, 31.5%-14.4% (p=0.0008) and of moderate FI from 68.5% to 36.9%. RESULTS: 111 patients were included. They had a baseline median (IQR) ELCSA score=8 (7-11) that changed to 6 (4-9) (p<0.0001). Severe FI according to ELCSA changed from 31.5% to 14.4% (p<0.001) and moderate from 68.5% to 36.9% (p<0.001). We found no differences in nutritional status regarding height for age (49.5% vs 51.3%, p=0.76), weight for height (42.5% vs 59.1%, p=0.75) or body mass index for age (38% vs 46%, p=0.42) CONCLUSION: The programme reduced FI in families by improving its level to mild or moderate. Children who entered the programme maintained an appropriate nutritional status despite the considerable risk of malnutrition described for oncological paediatric patients and paediatric solid organ transplantation receptors.

RESUMEN

The benefits of mycorrhizal interactions are only known in 8 of 210 recognized Agave taxa. We evaluated the effects of autochthonous and allochthonous arbuscular mycorrhizal fungi (AMF) on growth and nutrient assimilation in Agave maximiliana. The autochthonous consortium (Cn) of eight species was propagated from the rhizospheric soil of A. maximiliana, while Claroideoglomus claroideum (Cc) and Claroideoglomus etunicatum (Ce) were employed as allochthonous AMF. Six treatments were included in the study: Cn, Ce, Cc, Ce + Cc, Tf (fertilized control), and Tn (non-fertilized control, not inoculated). Mycorrhizal colonization increased over time, and the colonization percentages produced by Cn and the allochthonous AMF, both alone and mixed together, were equal at 6, 12, and 18 months. Height increased steadily and was higher in AMF-treated plants from seven months onward. Growth indicators of AMF-treated and AMF-free plants were equal at 6 months, but the beneficial effects of allochthonous and autochthonous AMF were evident in all growth indicators at 18 months and in sugar and mineral (P, K, Ca, Mg, and Fe) content. Arbuscular mycorrhizal fungi significantly improved all growth parameters of A. maximiliana regardless of the origin of the inoculums. This is the first study to report the positive effects of AMF colonization in A. maximiliana.

RESUMEN

Introducción: Las miopatías inflamatorias idiopáticas (MII) constituyen un grupo heterogéneo de enfermedades que comprometen la musculatura esquelética y se manifiestan por debilidad y signos inflamatorios en la biopsia muscular. El objetivo de este estudio es hacer una caracterización epidemiológica de una cohorte de pacientes con MII en una población del suroccidente colombiano. Metodología: De forma retrospectiva, se revisaron las historias clínicas de pacientes con diagnóstico de MII que fueron tratados en un hospital de cuarto nivel de complejidad en Cali, Colombia, entre el 2011 y el 2017. Se recolectaron variables demográficas, clínicas, serológicas y de tratamiento. Resultados: Se identificaron 72 pacientes con MII, mayoritariamente mujeres (n = 54, 75%). La media de edad al inicio de los síntomas fue de 37,11 ± 19,18 años. Las principales MII fueron dermatomiositis (DM) y polimiositis, las cuales se presentaron en 35 (48,6%) y 25 pacientes (34,7%), respectivamente. Veintiocho pacientes (38,8%) presentaban enfermedad autoinmune asociada, siendo el lupus eritematoso sistémico la más frecuente, al presentarse en7 (9,72%) pacientes. La biopsia de músculo se realizó en 25 pacientes (34,7%), mientras que28 (38,8%) tenían anticuerpos antinucleares positivos. La mediana de la creatinfosfoquinasa fue de 877,5 mg/dL (163,5-4.358,3). Sesenta y siete pacientes (93,1%) fueron tratados con glucocorticoides y 18 (25%) con rituximab (RTX) como monoterapia o combinado con otro fármaco inmunosupresor. Conclusiones: La DM es la condición clínica más frecuente, es común en mujeres y se presenta en la cuarta década de vida. Los tratamientos con los que más se obtuvo mejoría clínica fueron los glucocorticoides, seguidos del RTX en monoterapia o combinado con otros inmunosupresores.

Background: Idiopathic inflammatory myopathies (IIM) are a heterogeneous group of diseases characterised by skeletal muscle involvement, manifested by weakness and inflammatory signs in the muscle biopsy. The objective of this article is to describe the clinical, laboratory, and treatment features of a cohort of patients with IIM in southwest Colombia. Methods: A retrospective review was conducted on the medical records of patients diagnosed with IIM treated at a fourth-level complexity hospital in Cali, Colombia, from 2011 to 2017. Demographic, clinical, serological, and treatment data were collected. Results: A total of 72 patients with IIM were identified, mostly women (n = 54,75%). The mean age at onset of symptoms was 37.11 ± 19.18 years. The main subtypes of IIM were dermatomyositis (DM) and polymyositis, occurring in 35 patients (48.6%) and 25 patients (34.7%), respectively. Twenty-eight patients (38.8%) had associated autoimmune disease, with syste mic lupus erythematosus being the most frequent in 7 (9.72%) patients. Muscle biopsy was performed in 25 patients (34.7%), while 28 (38.8%) had positive antinuclear antibodies. The median creatine phosphokinase was 877.5 mg/dL (163.5-4358.3). Sixty-seven patients (93.1%) were treated with glucocorticoids, and 18 (25%) patients were treated with rituximab (RTX) as monotherapy or combined with another immunosuppressant drug. Conclusions: DM is the most frequent subtype of IIM, being common in women and occurring in the fourth decade of life. The most used treatments were glucocorticoids, followed by RTX monotherapy, or combined with other immunosuppressants.

RESUMEN

AIMS: Freedom from atrial fibrillation (AF) at 1 year can be achieved in 50-70% of patients undergoing catheter ablation. Recurrent AF early after ablation most commonly terminates spontaneously without further interventional treatment but is associated with later recurrent AF. The aim of this investigation is to identify clinical and procedural factors associated with recurrence of AF early after ablation. METHODS AND RESULTS: We retrospectively analysed data for recurrence of AF within the first 3 months after catheter ablation from the randomized controlled AXAFA-AFNET 5 trial, which demonstrated that continuous anticoagulation with apixaban is as safe and as effective compared to vitamin K antagonists in 678 patients undergoing first AF ablation. The primary outcome of first recurrent AF within 90 days was observed in 163 (28%) patients, in which 78 (48%) patients experienced an event within the first 14 days post-ablation. After multivariable adjustment, a history of stroke/transient ischaemic attack [hazard ratio (HR) 1.54, 95% confidence interval (CI) 0.93-2.6; P = 0.11], coronary artery disease (HR 1.85, 95% CI 1.20-2.86; P = 0.005), cardioversion during ablation (HR 1.78, 95% CI 1.26-2.49; P = 0.001), and an age:sex interaction for older women (HR 1.01, 95% CI 1.00-1.01; P = 0.04) were associated with recurrent AF. The P-wave duration at follow-up was significantly longer for patients with AF recurrence (129 ± 31 ms vs. 122 ± 22 ms in patients without AF, P = 0.03). CONCLUSION: Half of all early AF recurrences within the first 3 months post-ablation occurred within the first 14 days post-ablation. Vascular disease and cardioversion during the procedure are strong predictors of recurrent AF. P-wave duration at follow-up was longer in patients with recurrent AF. TRIAL REGISTRATION: Clinicaltrials.gov identifier NCT02227550.

RESUMEN

BACKGROUND: Paraneoplastic cerebellar degeneration (PCD) is a rare complication of some malignant cancers. It is most commonly described in women with gynecologic or breast malignancies; however, there have been reports in other types of cancers. Symptoms include ataxia, dysarthria, and tremors, which could be the first manifestations of an underlying malignancy. CASE DESCRIPTION: A 50-year-old woman had an acute PCD with anti-Yo antibodies from an underlying breast invasive ductal carcinoma. She presented with intracranial hypertension in the posterior cranial fossa that required an emergent decompressive craniectomy. CONCLUSIONS: PCD is an uncommon disease that may manifest initially as posterior cranial fossa hypertension and subsequent acute hydrocephalus owing to diffuse cerebellar swelling. To our knowledge, this is the first described case of an anti-Yo PCD that has manifested as acute posterior cranial fossa hypertension owing to diffuse cerebellar edema. Early diagnosis and treatment should be pursued to improve long-term outcomes.
