RESUMO

OBJECTIVES: The objectives of this real-life study were to analyze the reversion of chronic migraine (CM) to episodic migraine (EM) with fremanezumab, evaluate its benefit on the symptomatology, and determine the influence of possible clinical features on the reversion. BACKGROUND: The clinical manifestations of CM have a high impact on the quality of life of patients, and monoclonal antibodies such as fremanezumab are used as prophylactic treatment. METHODS: Diagnosed CM patients treated for at least 3 months with monthly fremanezumab were interviewed. The data to assess efficacy were before treatment and at the time of the interview: monthly headache days (MHDs), daily headache hours (DHHs), monthly symptomatic medication days (MSMDs), percentage of patients with symptomatic medication overuse (SMO), and pain intensity with the numerical rating scale (NRS) score. Possible predictors of reversion were analyzed: percentage of patients treated for at least 12 months, hypertension, diabetes mellitus, depression, anxiety, symptomatic control with non-steroidal anti-inflammatory drugs (NSAIDs), triptans or both, and amitriptyline prophylaxis. RESULTS: A total of 54 patients were included, of whom 40 (74.1%) were converters to EM. There were significant improvements in converters compared to pre-treatment in MHDs (28.0 vs. 5.0 days), as well as on the variables DHHs, MSMDs, and SMO. The percentage of erenumab failures was significantly higher in non-converters than in converters, as was the percentage of patients with anxiety. CONCLUSIONS: High reversion from CM to EM was achieved with fremanezumab and notable symptomatological improvement, establishing previous failure to erenumab and anxiety as possible detrimental factors for reversion.

RESUMO

Objective. To determine the effectiveness of a pharma ceutical intervention, based on the CMO methodology (capac ity, motivation and opportunity), to decrease the prevalence of the PIMDINAC concept (potentially inappropriate medica tion+drug interactions+non-adherence to concomitant med ication) in people living with HIV infection. Material and methods. Longitudinal prospective multi center study, conducted between October 2021 and October 2022. Patients living with HIV older than 65 years, on antiret roviral treatment and concomitant drug prescription were included. Demographic, clinical, and pharmacotherapeutic variables were collected. Pharmaceutical care was provided for 6 months according to the CMO model in each patient. The main variable was the percentage of patients who simultane ously fulfilled the PIMDINAC concept, comparing the baseline value with the same value at the end of the study. In addi tion, the percentage of patient’s adherent to concomitant and antiretroviral treatment and the percentage of patients meet ing the pharmacotherapeutic targets established for the pre scribed medication at 24 weeks of follow-up were compared. Results. Sixty-eight patients were included. Seventy-two percent were men, with a median age of 68 years. The medi an number of concomitant drugs was 7. A 60.6% of the pa tients had polypharmacy. The prevalence of the presence of the PIMDINAC concept decreased significantly (10.3 vs. 0%). In isolation, each of the aspects also decreased significantly (p <0.031) The percentage of patients who met the objectives improved significantly from 48,5 at baseline to 88.2 (p <0.001). Conclusions. The pharmaceutical intervention based on the CMO methodology significantly decreased the prevalence of the PIMDINAC concept and increased the number of pa tients who achieved the objectives, optimising their pharma cotherapy (AU)

RESUMO

To determine the association between women's autonomy and the presence of childhood anemia in children under five years of age in Peru, a cross-sectional study utilizing data from the 2019 Demographic and Family Health Survey was carried out. The study employed generalized linear models with a Poisson distribution and log link function. Crude and adjusted prevalence ratios (aPR) were calculated, along with their corresponding 95% confidence intervals (CI), to assess the association of interest. A total of 15,815 women and their children under five years of age were analyzed. The prevalence of childhood anemia was 30.4% (95%CI: 29.5-31.3%), while the proportions of low, moderate and high autonomy of the mothers were 44.5%, 38.4% and 17.1%, respectively. Children under five years of age of women with a low level of autonomy were more likely to have anemia (aPR: 1.10; 95%CI: 1.00-1.21). Three out of ten children under five years of age suffer from anemia, and four out of ten mothers have a low level of autonomy. A low level of women's autonomy was associated with a higher probability of anemia in children under 5 years of age.

RESUMO

We sought to test the hypothesis that the cardiovascular responses to isolated muscle metaboreflex activation would be blunted in patients with cirrhosis. Eleven patients with cirrhosis and 15 healthy controls were evaluated. Blood pressure (BP; oscillometric method), contralateral forearm blood flow (FBF; venous occlusion plethysmography), and heart rate (HR; electrocardiogram) were measured during baseline, isometric handgrip at 30% of maximal voluntary contraction followed by postexercise ischemia (PEI). Forearm vascular conductance (FVC) was calculated as follows: (FBF / mean BP) × 100. Changes in HR during handgrip were similar between groups but tended to be different during PEI (controls: Δ 0.5 ± 1.1 bpm vs. cirrhotic patients: Δ 3.6 ± 1.0 bpm, P = 0.057). Mean BP response to handgrip (controls: Δ 20.9 ± 2.7 mm Hg vs. cirrhotic patients: Δ 10.6 ± 1.5 mm Hg, P = 0.006) and PEI was attenuated in cirrhotic patients (controls: Δ 16.1 ± 1.9 mm Hg vs. cirrhotic patients: Δ 7.2 ± 1.4 mm Hg, P = 0.001). In contrast, FBF and FVC increased during handgrip and decreased during PEI similarly between groups. These results indicate that an abnormal muscle metaboreflex activation explained, at least partially, the blunted pressor response to exercise exhibited by cirrhotic patients. Novelty: Patients with cirrhosis present abnormal muscle metaboreflex activation. BP response was blunted but forearm vascular response was preserved. HR response was slightly elevated.

RESUMO

We have previously shown that the combination of radiotherapy with human umbilical-cord-derived mesenchymal stromal/stem cells (MSCs) cell therapy significantly reduces the size of the xenotumors in mice, both in the directly irradiated tumor and in the distant nonirradiated tumor or its metastasis. We have also shown that exosomes secreted from MSCs preirradiated with 2 Gy are quantitatively, functionally and qualitatively different from the exosomes secreted from nonirradiated mesenchymal cells, and also that proteins, exosomes and microvesicles secreted by MSCs suffer a significant change when the cells are activated or nonactivated, with the amount of protein present in the exosomes of the preirradiated cells being 1.5 times greater compared to those from nonirradiated cells. This finding correlates with a dramatic increase in the antitumor activity of the radiotherapy when is combined with MSCs or with preirradiated mesenchymal stromal/stem cells (MSCs*). After the proteomic analysis of the load of the exosomes released from both irradiated and nonirradiated cells, we conclude that annexin A1 is the most important and significant difference between the exosomes released by the cells in either status. Knowing the role of annexin A1 in the control of hypoxia and inflammation that is characteristic of acute respiratory-distress syndrome (ARDS), we designed a hypothetical therapeutic strategy, based on the transplantation of mesenchymal stromal/stem cells stimulated with radiation, to alleviate the symptoms of patients who, due to pneumonia caused by SARS-CoV-2, require to be admitted to an intensive care unit for patients with life-threatening conditions. With this hypothesis, we seek to improve the patients' respiratory capacity and increase the expectations of their cure.

RESUMO

OBJECTIVE: To investigate the effects of aerobic exercise on the cardiac baroreflex function and vascular reactivity in patients with cirrhosis. METHODS: Thirteen patients with cirrhosis were submitted to exercise and control intervention. At baseline and at 30 and 60 min following intervention, we evaluated cardiac baroreflex sensitivity (cBRS) and the baroreflex effectiveness index (BEI) using sequence technique. Vascular reactivity was assessed inducing reactive hyperemia before and 60 min after intervention. RESULTS: At baseline, there was no difference (P interaction = 0.848) between exercise (from 3.0 ± 0.34 to 14.60 ± 1.06 ml/100ml/min) and control sessions (from 2.38 ± 0.10 to 13.73 ± 1.05 ml/100ml/min) regarding the increase in forearm blood flow during reactive hyperemia. However, this response was higher postexercise (from 3.38 ± 0.31 to 16.58 ± 1.58 ml/100ml/min) than postcontrol intervention (from 2.04 ± 0.23 to 11.98 ± 1.16 ml/100ml/min, P interaction < 0.001). BEI increased at 30- and 60-min postexercise (from 32 ± 7 to 42 ± 7 and 46 ± 7%), but not after control intervention (from 33 ± 6 to 31 ± 5 and 33 ± 7%, P interaction = 0.014). In contrast, cBRS decreased at 30-min postexercise (from 10.3 ± 1.9 to 8.2 ± 1.4 and 10.3 ± 2.1 ms/mmHg) and increased postcontrol intervention (from 7.9 ± 0.9 to 10.5 ± 1.5 and 10.3 ± 1.3 ms/mmHg, P interaction = 0.012). CONCLUSION: The results suggest that a single bout of aerobic exercise improved cardiac baroreflex function and increased vascular reactivity in patients with early-stage cirrhosis.

RESUMO

Monogeneans are parasitic flatworms that may be a threat for finfish aquaculture. In this study, the anthelmintic activity of two terpenes, geraniol and ß-citronellol, was tested in vitro against ancyrocephalin and diplectanid monogeneans. Experiments were performed in both water and a culture medium. We observed that monogeneans in culture medium may be more tolerant to treatments compared with bioassays performed only in water. Concentrations of 300 mg/L of both compounds were required to kill 100% of monogeneans at 1 h postexposure. The toxicity of ß-citronellol to fish was not evaluated. However, geraniol at 300 mg/L and 150 mg/L killed juvenile Nile Tilapia Oreochromis niloticus and White Snook Centropomus viridis, respectively, after a few minutes. Therefore, the present work suggests that other alternatives should be studied for use against monogeneans in aquaculture.

RESUMO

Metastasis is the leading cause of cancer-related deaths and despite measurable progress in the field, underlying mechanisms are still not fully understood. Circulating tumor cells (CTCs) disseminate within the bloodstream, where most of them die due to the attack of the immune system. On the other hand, recent evidence shows active interactions between CTCs and platelets, myeloid cells, macrophages, neutrophils, and other hematopoietic cells that secrete immunosuppressive cytokines, which aid CTCs to evade the immune system and enable metastasis. Platelets, for instance, regulate inflammation, recruit neutrophils, and cause fibrin clots, which may protect CTCs from the attack of Natural Killer cells or macrophages and facilitate extravasation. Recently, a correlation between the commensal microbiota and the inflammatory/immune tone of the organism has been stablished. Thus, the microbiota may affect the development of cancer-promoting conditions. Furthermore, CTCs may suffer phenotypic changes, as those caused by the epithelial-mesenchymal transition, that also contribute to the immune escape and resistance to immunotherapy. In this review, we discuss the findings regarding the collaborative biological events among CTCs, immune cells, and microbiome associated to immune escape and metastatic progression.

RESUMO

Terpenes are naturally produced compounds with a broad range of biological activities. Currently, there is limited information regarding the anthelminthic effect of terpenes against monogenean parasites of fish. The aim of this work was to evaluate the in vitro efficacy of two terpenes [α-terpinene and (+)-limonene oxide] against ancyrocephalid monogeneans found on farmed Nile tilapia (Oreochromis niloticus). (+)-Limonene oxide was more effective in killing these parasites than α-terpinene, with 86 and 90% mortality at concentrations of 36 and 55.4 mg/L, respectively, with a 5-h treatment. The estimated 5-h EC50 of (+)-limonene oxide was 4.8 mg/L. Even though this compound has the potential to be used as an anthelmintic compound in finfish aquaculture, before in vivo experiments are performed, additional studies are needed to find a more effective concentration, as well as to evaluate other terpenic compounds.

RESUMO

The in vitro and in vivo antihelmintic activity of cobalt(II), copper(II) and zinc(II) coordination compounds of tinidazole (tnz) were investigated in cultivated spotted rose snapper, infested with dactylogyrid monogeneans. The tinidazole coordination compounds [Co(tnz)2Cl2], [Co(tnz)2Br2], [Cu(tnz)2Cl2], [Cu(tnz)2Br2], [Zn(tnz)2Cl2] and [Zn(tnz)2Br2] were synthesized and spectroscopically characterized. Their molecular structures were determined by their single crystal X-ray diffraction. The metal ions presented distorted tetrahedral geometries, with an intramolecular bifurcated lone pair SO⋯π, from the sulfone group with the imidazolic ring, which contributed to the stability of the compounds in solid state and in solution. Adults of dactylogyrids were exposed in vitro to tinidazole and its coordination compounds. The effective median concentrations of copper(II) coordination compounds were lower than those of cobalt(II) and zinc(II), tnz showed no activity. In vivo oral intubation tests were carried out with [Cu(tnz)2Br2], [Zn(tnz)2Br2] and tnz on snappers infected with dactylogyrids, where the copper(II) compound showed better activity. The absorption and distribution assessment for the [Cu(tnz)2Br2], showed that copper concentrations in liver were significantly higher than in blood and gills, indicating bioaccumulation in this organ. In vivo baths of [Cu(tnz)2Br2] at 25mg/L showed an effective (95% at 8h) antihelmintic effect, while [Zn(tnz)2Br2] had low antihelmintic efficacy. This study indicates that [Cu(tnz)2Br2] has an effective antihelmintic activity towards dactylogyrids monogeneans affecting cultivated spotted red snapper.

RESUMO

Collaborative healthcare environments offer potential benefits, including enhancing the healthcare quality delivered to patients and reducing costs. As a direct consequence, sharing of electronic health records (EHRs) among healthcare providers has experienced a noteworthy growth in the last years, since it enables physicians to remotely monitor patients' health and enables individuals to manage their own health data more easily. However, these scenarios face significant challenges regarding security and privacy of the extremely sensitive information contained in EHRs. Thus, a flexible, efficient, and standards-based solution is indispensable to guarantee selective identity information disclosure and preserve patient's privacy. We propose a privacy-aware profile management approach that empowers the patient role, enabling him to bring together various healthcare providers as well as user-generated claims into an unique credential. User profiles are represented through an adaptive Merkle Tree, for which we formalize the underlying mathematical model. Furthermore, performance of the proposed solution is empirically validated through simulation experiments.

RESUMO

En los últimos años se han publicado algunos artículos que plantean las posibilidades que puede aportar el uso de la terapia celular para el tratamiento de ciertas retinopatías. El presente trabajo pretende comunicar la factibilidad y seguridad de la implantación de células madre en pacientes con degeneraciones de retina, como la retinosis pigmentaria y la degeneración macular seca relacionada con la edad, a partir de un estudio preliminar, realizado en pacientes atendidos en la consulta de oftalmología del Hospital General Docente Dr. Ernesto Guevara de La Serna, en la provincia de Las Tunas, Cuba. Los mismos fueron tratados con implantación de células madre adultas autólogas, procedentes de la médula ósea, y movilizadas a la sangre periférica mediante el factor estimulador de colonias de granulocitos. Se hizo aplicación local por las vías retrobulbar y peribulbar en ambos ojos, e intravitrea sólo en el ojo más afectado. El resto de las células obtenidas se inyectó por vía endovenosa. Se trataron 30 pacientes en ambos ojos en el periodo de marzo a agosto del presente año. Las variables analizadas fueron: agudeza visual y complicaciones del método de implante. Se pudo comprobar que la mejoría visual en ellos fue en el ojo del triple implante, aplicación intravitrea. En ningún caso hubo reacciones adversas generales y se presentaron complicaciones locales en dos casos, debido a uveítis anterior ligera en un ojo, después del implante de células madre, con resolución a las 72 horas con colirios esteroideos. El estudio evidenció la seguridad del método aplicado y los resultados obtenidos son alentadores, pues crean nuevas perspectivas que pueden contribuir significativamente al tratamiento de estas retinopatías (AU)


In recent years there have been some articles that show the possibilities that the use of cell therapy can add to the treatment of certain retinopathies. This paper aims to report the feasibility and safety of stem cell implantation in patients with retinal degenerations, such as retinitis pigmentosa and dry macular degeneration related to age, starting from a preliminary study carried out in patients seen in the ophthalmology consultation of Dr. Ernesto Guevara de La Serna General Teaching Hospital in Las Tunas province, Cuba. They were treated with implantation of autologous adult stem cells from bone marrow and carried to the peripheral blood by the granulocyte colony-stimulating factor. Local application was made by retrobulbar and peribulbar pathways in both eyes and intra-vitreous only in the affected eye. The rest of the cells obtained were injected intravenously. 30 patients were treated in both eyes from March to August, this year. The variables analyzed were: visual acuity and complications of the implant method. It was proved that their visual improvement was in the eye of the triple implant, intra-vitreous application. No case showed general adverse reactions and local complications occurred only in two cases, due to slight anterior uveitis in one eye after the implantation of stem cells, and solved within 72 hours with steroid eye drops. The study evidenced the safety of the method used and the results obtained are encouraging, since they create new perspectives that can contribute significantly to the treatment of these retinopathies (AU)

RESUMO

BACKGROUND: Lung cancer remains one of the most prevalent forms of cancer. Radiotherapy, with or without other therapeutic modalities, is an effective treatment. Our objective was to report on the use of radiotherapy for lung cancer, its variability in our region, and to compare our results with the previous study done in 2004 (VARA-I) in our region and with other published data. METHODS: We reviewed the clinical records and radiotherapy treatment sheets of all patients undergoing radiotherapy for lung cancer during 2007 in the 12 public hospitals in Andalusia, an autonomous region of Spain. Data were gathered on hospital, patient type and histological type, radiotherapy treatment characteristics, and tumor stage. RESULTS: 610 patients underwent initial radiotherapy. 37% of cases had stage III squamous cell lung cancer and were treated with radical therapy. 81% of patients with non-small and small cell lung cancer were treated with concomitant chemo-radiotherapy and the administered total dose was ≥60 Gy and ≥45 Gy respectively. The most common regimen for patients treated with palliative intent (44.6%) was 30 Gy. The total irradiation rate was 19.6% with significant differences among provinces (range, 8.5-25.6%; p<0.001). These differences were significantly correlated with the geographical distribution of radiation oncologists (r=0.78; p=0.02). Our results were similar to other published data and previous study VARA-I. CONCLUSIONS: Our results shows no differences according to the other published data and data gathered in the study VARA-I. There is still wide variability in the application of radiotherapy for lung cancer in our setting that significantly correlates with the geographical distribution of radiation oncologists.

RESUMO

Credential-based authorization offers interesting advantages for ubiquitous scenarios involving limited devices such as sensors and personal mobile equipment: the verification can be done locally; it offers a more reduced computational cost than its competitors for issuing, storing, and verification; and it naturally supports rights delegation. The main drawback is the revocation of rights. Revocation requires handling potentially large revocation lists, or using protocols to check the revocation status, bringing extra communication costs not acceptable for sensors and other limited devices. Moreover, the effective revocation consent--considered as a privacy rule in sensitive scenarios--has not been fully addressed. This paper proposes an event-based mechanism empowering a new concept, the sleepyhead credentials, which allows to substitute time constraints and explicit revocation by activating and deactivating authorization rights according to events. Our approach is to integrate this concept in IdM systems in a hybrid model supporting delegation, which can be an interesting alternative for scenarios where revocation of consent and user privacy are critical. The delegation includes a SAML compliant protocol, which we have validated through a proof-of-concept implementation. This article also explains the mathematical model describing the event-based model and offers estimations of the overhead introduced by the system. The paper focus on health care scenarios, where we show the flexibility of the proposed event-based user consent revocation mechanism.

RESUMO

Lafora disease is a progressive myoclonus epilepsy caused by mutations in the EPM2A gene encoding laforin or in the EPM2B gene encoding malin. It is characterized by the presence of polyglucosan intracellular inclusion bodies (Lafora bodies) in brain and other tissues. Targeted disruption of Epm2a or Epm2b genes in mice produced widespread neuronal degeneration and accumulation of Lafora bodies in neuronal and nonneuronal tissues. Here we analyzed the neurologic alterations produced by disruption of the laforin gene in Epm2a mice and compared them to those in malin-deficient mice. Both Epm2a and Epm2b mice showed altered motor activity, impaired motor coordination, abnormal hind limb clasping, and episodic memory deficits. Epm2a mice also had tonic-clonic seizures, whereas both Epm2a and Epm2b mice had spontaneous single spikes, spike-wave, polyspikes, and polyspike-wave complexes with correlated myoclonic jerks. Neurologic alterations observed in the mutants were comparable and correlated with the accumulation of abundant Lafora bodies in the cerebral cortex, the hippocampus, the basal ganglia, the cerebellum, and the brainstem, suggesting that these inclusions could cause cognitive and behavioral deterioration. Thus, both Epm2a and Epm2b mice exhibit many pathologic aspects seen in patients with Lafora disease and may be valuable for the study of this disorder.
