A Systematic review of the presence and participation of students with intellectual disabilities in Spanish universities.

Inclusive education remains a challenge to be embraced by the national educational system, and this challenge becomes even more pronounced when considering the access and participation of young individuals with intellectual disabilities (ID) in higher education. The present systematic review aims to delve into the scientific literature addressing the theme of the presence of students with ID in Spanish university classrooms. To achieve this, a thorough examination of 34 scientific articles published between 2012 and 2022 was conducted across the databases of Dialnet, RedALyC, SCOPUS, Web of Science, and Google Scholar. Through the analysis of the selected studies, a research trend regarding the inclusion of students with ID in Spanish universities is identified, and the results are summarized. These results indicate a disparity between the increasing response of Spanish universities to students with ID and the limited production of scientific literature on the subject. The review concludes by emphasizing the need to promote high-quality inclusive research processes within the university environment, with a focus on accessibility and equal opportunities for young individuals with ID in higher education.

Keeping prior anticoagulation treatment in the acute phase of ischaemic stroke: the REKOALA study.

INTRODUCTION: A consensus on the management of anticoagulated patients in the acute phase of ischaemic stroke has not yet been established. We aimed to evaluate clinical outcomes in such patients based on the continuation or discontinuation of anticoagulation. METHODS: Retrospective study of patients with acute ischaemic stroke and cardioembolic source receiving anticoagulant therapy is done. Patients were classified based on the continuation or discontinuation of anticoagulation at admission. Clinical outcomes, haemorrhagic and ischaemic events were assessed. Multivariate logistic regression analysis, propensity score matching (PSM) analysis and a sub-analysis of patients with severe ischaemic stroke at admission (NIHSS score ≥ 15) were performed. RESULTS: Anticoagulation was continued in 147 (78.8%) of 186 patients. Patients continuing anticoagulant had lower NIHSS (median 5 vs 18, p < 0.001). There were no differences in haemorrhagic or ischaemic events. In the multivariate analysis, good functional outcome at discharge was higher in the continuation group, OR (CI95%) 3.77 (1.2-11.2). PSM analysis adjusted for potential confounders such as NIHSS had higher rates of good functional outcomes at discharge (80% vs 36%, p = 0.004) and at 90 days (76% vs 44%, p = 0.042) in the continuation group. Patients with severe stroke in this group had lower 90-day mortality (34.6% vs 62.5%, p = 0.045) and higher rates of good clinical outcome at discharge (33.3% vs 8.3%, p = 0.032). No differences were observed in 90-day haemorrhagic or ischaemic events. CONCLUSION: Continuation of anticoagulation in patients with acute ischaemic stroke and cardioembolic source did not increase the risk of intracranial haemorrhage and may be associated with better functional outcomes.

Variability in Definitions and Criteria of Extrauterine Growth Restriction and Its Association with Neurodevelopmental Outcomes in Preterm Infants: A Narrative Review.

Extrauterine growth restriction (EUGR) has been used in the literature and clinical practice to describe inadequate growth in preterm infants. Significant variability is seen in the criteria for EUGR, with no standard definition reached to date. Moreover, no consensus on the optimal timing for assessment or the ideal growth monitoring tool has been achieved, and an ongoing debate persists on the appropriate terminology to express poor postnatal growth. To ensure an adequate understanding of growth and early intervention in preterm infants at higher risk, it is critical to relate the diagnostic criteria of EUGR to the ability to predict adverse outcomes, such as neurodevelopmental outcomes. This narrative review was conducted to present evidence that evaluates neurodevelopmental outcomes in preterm infants with EUGR, comparing separately the different definitions of this concept by weight (cross-sectional, longitudinal and "true" EUGR). In this article, we highlight the challenges of comparing various published studies on the subject, even when subclassifying by the definition of EUGR, due to the significant variability on the criteria used for each definition and for the evaluation of neurodevelopmental outcomes in different papers. This heterogeneity compromises the obtention of a single firm conclusion on the relation between different definitions of EUGR and adverse neurodevelopmental outcomes.

Clinical report of Bosma arhinia microphthalmia syndrome with a new variant on SMCHD1 gene. A case report.

The Bosma syndrome (BAMS: Bosma arhinia microphthalmia syndrome) is a condition first described in 1972. Since then, several reviews have published the cases looking for diagnostic criteria and associated genetic alterations. The mutation in the SMCHD1 gene (Structural Maintenance of Chromosomes flexible Hinge Domain containing protein 1) seems to explain a part of the development of the phenotype. Not all cases show the same alterations or meet the classic diagnostic criteria, and few have undergone genetic analysis. We present a case with a new variant in this gene and an update of the literature on this syndrome with the aim of improving the diagnosis and follow-up of these patients.

Early hospital discharge through prediction of post-thyroidectomy hypoparathyroidism.

INTRODUCTION: Hypoparathyroidism is the most common postsurgical complication of total thyroidectomy. Furthermore, it is the main cause of prolonged hospitalisation after this procedure. OBJECTIVE: To predict the probability of post-thyroidectomy hypocalcaemia according to the levels of intact parathyroid hormone (iPTH), as well as to determine the needs for treatment with exogenous calcium according to the levels of serum calcium (Ca). MATERIALS AND METHODS: Retrospective study was carried out on patients who underwent total thyroidectomy between January 2017 and January 2020 at Los Arcos del Mar Menor University Hospital (HULAMM). iPTH and Ca levels ​​were measured at 4, 24 and 48 h after the surgery. Follow-up was 6 months. RESULTS: Ninety-four patients were operated on. Temporary and permanent postoperative hypoparathyroidism percentages were, respectively, 51.06% and 6.38%. iPTH level 24 h after the procedure was the most reliable predictor of post-thyroidectomy temporary hypoparathyroidism (Area Under the ROC Curve (AUC) = 0.933, p < .001). iPTH levels ​​≥29 pg/mL predicted normal parathyroid metabolism. CONCLUSIONS: The combined values of iPTH and Ca levels 24 h after thyroidectomy seems to be a reliable, safe and efficient method to control the post-thyroidectomy hypoparathyroidism. Our protocol could reduce the hospital stay of patients at low risk of hypocalcaemia, allowing them to be discharged from the hospital on the first postoperative morning and identifying patients at high risk of hypocalcaemia early.

Innovative Solutions for Patients Who Undergo Craniectomy: Protocol for a Scoping Review.

BACKGROUND: Decompressive craniectomy (DC) is a widely used procedure to alleviate high intracranial pressure. Multidisciplinary teams have designed and implemented external medical prototypes to improve patient life quality and avoid complications following DC in patients awaiting cranioplasty (CP), including 3D printing and plaster prototypes when available. OBJECTIVE: This scoping review aims to understand the extent and type of evidence about innovative external prototypes for patients who undergo DC while awaiting CP. METHODS: This scoping review will use the Joanna Briggs Institute methodology for scoping reviews. This scoping review will include noninvasive medical devices for adult patients who undergo DC while waiting for CP. The search strategy will be implemented in MEDLINE, Embase, Web of Science, Scielo, Scopus, and the World Health Organization (WHO) Global Health Index Medicus. Patent documents were also allocated in Espacenet, Google Patents, and the World Intellectual Property Organization (WIPO) database. RESULTS: This scoping review is not subject to ethical approval as there will be no involvement of patients. The dissemination plan includes publishing the review findings in a peer-reviewed journal and presenting results at conferences that engage the most pertinent stakeholders in innovation and neurosurgery. CONCLUSIONS: This scoping review will serve as a baseline to provide evidence for multidisciplinary teams currently designing these noninvasive innovations to reduce the risk of associated complications after DC, hoping that more cost-effective models can be implemented, especially in low- and middle-income countries.

Breast cancer survivors suffering from lymphedema: What really do affect to corporeality/body image? A qualitative study.

Breast cancer-related lymphedema is currently one of the most serious complications that most affect the quality of life of women undergoing breast cancer. The aim of this study was to explore in-depth the experience of women who suffer from lymphoedema after breast cancer and how does this condition affect corporeality, with no judgements. For this purpose, a qualitative methodology was followed. In-depth interviews, interviewer's field notes and participants' letters were used for data collection. The participants were twenty Spanish women with lymphoedema after overcome a breast cancer in the past. Healthcare specialists with experience in the topic were also included. Results showed 2 main categories: "From cancer to lymphedema, another disease another disease" and "Potential for transition and transformation towards a new way of life". As a conclusion, the difficulty in accessing adequate treatment, the need for greater awareness of lymphedema and the importance of the emotional and psychological dimension of this chronic disease. Highlighting the attitudes that these women develop for self-care and the concept of new corporeality. After breast cancer, women with lymphedema experience a drastic change that affects all areas of their lives. The adaptation process, and the search for resources and aid, play a fundamental role in overcoming this process.

The ABCG2 protein in vitro transports the xenobiotic thiabendazole and increases the appearance of its residues in milk.

Thiabendazole (TBZ) is a broad-spectrum anthelmintic and fungicide used in humans, animals, and agricultural commodities. TBZ residues are present in crops and animal products, including milk, posing a risk to food safety and public health. ABCG2 is a membrane transporter which affects bioavailability and milk secretion of xenobiotics. Therefore, the aim of this work was to characterize the role of ABCG2 in the in vitro transport and secretion into milk of 5-hydroxythiabendazole (5OH-TBZ), the main TBZ metabolite. Using MDCK-II polarized cells transduced with several species variants of ABCG2, we first demonstrated that 5OH-TBZ is efficiently in vitro transported by ABCG2. Subsequently, using Abcg2 knockout mice, we demonstrated that 5OH-TBZ secretion into milk was affected by Abcg2, with a more than 2-fold higher milk concentration and milk to plasma ratio in wild-type mice compared to their Abcg2-/- counterpart.

Identification and quantification of chain-pairing variants or mispaired species of asymmetric monovalent bispecific IgG1 monoclonal antibody format using reverse-phase polyphenyl chromatography coupled electrospray ionization mass spectrometry.

Developing a knob-into-hole asymmetric bispecific IgG1 monoclonal antibody (mAb) poses manufacturing challenges due to the expression of chain pairing variants, also called mispaired species, in the desired product. The incorrect pairing of light and heavy chains could result in heterogeneous mispaired species of homodimers, heterodimers, light chain swapping, and low molecular weight species (LMWS). Standard chromatography, capillary electrophoretic, or spectroscopic methods poorly resolve these from the main variants. Here, we report a highly sensitive reverse-phase polyphenyl ultra-high-performance liquid chromatography (RP-UHPLC) method to accurately measure mispaired species of Duet mAb format, an asymmetric IgG1 bispecific mAb, for both process development and quality control analytical tests. Coupled with electrospray ionization mass spectrometry (ESI-MS), it enabled direct online characterization of mispaired species. This single direct assay detected diverse mispaired IgG-like species and LMWS. The method resolved eight disulfide bonds dissociated LMWS and three mispaired LMWS. It also resolved three different types of IgG-like mispaired species, including two homodimers and one heterodimer. The characterization and quantification simultaneously enabled the cell line selection that produces a lesser heterogeneity and lower levels of mispaired species with the desired correctly paired product. The biological activity assessment of samples with increased levels of these species quantified by the method exhibited a linear decline in potency with increasing levels of mispaired species in the desired product. We also demonstrated the utility of the technique for testing in-process intermediate materials to determine and assess downstream purification process capability in removing diverse mispaired IgG-like species and LMWS to a certain level during the downstream purification process. Our investigation demonstrates that adopting this method was vital in developing asymmetric bispecific mAb from the initial stage of cell line development to manufacturing process development. Therefore, this tool could be used in the control strategy to monitor and control mispaired species during manufacturing, thus improving the quality control of the final product.

Repurposing rapid diagnostic tests to detect falsified vaccines in supply chains.

Substandard (including degraded) and falsified (SF) vaccines are a relatively neglected issue with serious global implications for public health. This has been highlighted during the rapid and widespread rollout of COVID-19 vaccines. There has been increasing interest in devices to screen for SF non-vaccine medicines including tablets and capsules to empower inspectors and standardise surveillance. However, there has been very limited published research focussed on repurposing or developing new devices for screening for SF vaccines. To our knowledge, rapid diagnostic tests (RDTs) have not been used for this purpose but have important potential for detecting falsified vaccines. We performed a proof-in-principle study to investigate their diagnostic accuracy using a diverse range of RDT-vaccine/falsified vaccine surrogate pairs. In an initial assessment, we demonstrated the utility of four RDTs in detecting seven vaccines. Subsequently, the four RDTs were evaluated by three blinded assessors with seven vaccines and four falsified vaccines surrogates. The results provide preliminary data that RDTs could be used by multiple international organisations, national medicines regulators and vaccine manufacturers/distributors to screen for falsified vaccines in supply chains, aligned with the WHO global 'Prevent, Detect and Respond' strategy.

Endocrine Adverse Events Related To Immune Checkpoint Inhibitor Treatment: Relationship Between Antibodies and Severity of Thyroid Dysfunction.

OBJECTIVE: The purpose of this study was to identify predictive and risk factors for the development of immune-related endocrinopathies and to analyze the incidence and characteristics of immune-related endocrinopathies in our population Design: A retrospective, single-centre cohort carried out at Gregorio Marañón Hospital between January 2018 -December 2019. METHODS: A total of 163 patients were enrolled. In January 2018 and December 2019, we treated patients who underwent ICI treatment in the Medical Oncology Department of General University Hospital Gregorio Marañón, a tertiary care public hospital in Madrid, as part of an observational, retrospective, single-center cohort study. RESULTS: Endocrinopathies were diagnosed in 19.5% of the patients (n=32). The tumours with the highest incidence of endocrinopathies were non-small cell lung cancer (25,9%), kidney cell cancer (25%) and hepatocarcinoma (20%). Among the 32 patients who developed endocrinopathy, 18,8%, 19,13%, and 21,28% received anti-CTLA-4, anti-PD-1 and anti-PDL-1, respectively. Thyroid dysfunction was the most frequent endocrinopathy (12,8%). A higher percentage of patients with negative antiTPO and antiTG antibodies developed G1 hypothyroidism compared to patients with positive antibodies who developed a higher proportion of G2 hypothyroidism. The presence of an initial phase of thyrotoxicity was not related to greater severity. We observed longer progression-free survival in patients who developed thyroid dysfunction. CONCLUSION: Pre-existing antibodies were independently associated with endocrinopathies. Moreover, our study let us conclude that the presence of thyroid autoantibodies may be related to its severity. It is important to determine anti-thyroid antibodies prior to the start of immunotherapy as a risk factor for thyroid dysfunction, which in turn is a prognostic marker.

Next-generation sequencing reveals remarkable genetic stability in primary and corresponding recurrent intestinal-type sinonasal adenocarcinoma.

BACKGROUND: Recurrent intestinal-type sinonasal adenocarcinoma (ITAC) can occur several years after primary treatment and with different histology. We aimed to clarify if such recurrences could be second primary tumors and to identify actionable mutations as targets for personalized treatment of recurrent ITAC. METHODS: Twelve pairs of primary and recurrent ITAC were histologically examined and analyzed by next-generation sequencing. RESULTS: Histological differences between primary and recurrent tumor pairs were observed in five cases. Frequent mutations included TP53, APC, TSC2, ATM, EPHA2, BRCA2, LRP1B, KRAS, and KMT2B. There was 86% concordance of somatic mutations between the tumor pairs, while four cases carried additional mutations in the recurrence. CONCLUSIONS: We found all cases to be clonal recurrences and not second primary tumors. Moreover, tumor pairs showed a remarkable genomic stability, suggesting that personalized treatment of a recurrence may be based on actionable molecular genetic targets observed in the primary tumor.

Biallelic variants in SNUPN cause a limb girdle muscular dystrophy with myofibrillar-like features.

Alterations in RNA-splicing are a molecular hallmark of several neurological diseases, including muscular dystrophies where mutations in genes involved in RNA metabolism or characterised by alterations in RNA splicing have been described. Here, we present five patients from two unrelated families with a limb-girdle muscular dystrophy (LGMD) phenotype carrying a biallelic variant in SNUPN gene. Snurportin-1, the protein encoded by SNUPN, plays an important role in the nuclear transport of small nuclear ribonucleoproteins (snRNPs), essential components of the spliceosome. We combine deep phenotyping, including clinical features, histopathology and muscle magnetic resonance image (MRI), with functional studies in patient-derived cells and muscle biopsies to demonstrate that variants in SNUPN are the cause of a new type of LGMD according to current definition. Moreover, an in vivo model in Drosophila melanogaster further supports the relevance of Snurportin-1 in muscle. SNUPN patients show a similar phenotype characterised by proximal weakness starting in childhood, restrictive respiratory dysfunction and prominent contractures, although interindividual variability in terms of severity even in individuals from the same family was found. Muscle biopsy showed myofibrillar-like features consisting of myotilin deposits and Z-disc disorganisation. MRI showed predominant impairment of paravertebral, vasti, sartorius, gracilis, peroneal and medial gastrocnemius muscles. Conservation and structural analyses of Snurportin-1 p.Ile309Ser variant suggest an effect in nuclear-cytosol snRNP trafficking. In patient-derived fibroblasts and muscle, cytoplasmic accumulation of snRNP components is observed, while total expression of Snurportin-1 and snRNPs remains unchanged, which demonstrates a functional impact of SNUPN variant in snRNP metabolism. Furthermore, RNA-splicing analysis in patients' muscle showed widespread splicing deregulation, in particular in genes relevant for muscle development and splicing factors that participate in the early steps of spliceosome assembly. In conclusion, we report that SNUPN variants are a new cause of limb girdle muscular dystrophy with specific clinical, histopathological and imaging features, supporting SNUPN as a new gene to be included in genetic testing of myopathies. These results further support the relevance of splicing-related proteins in muscle disorders.

Prescription trends for preservative free glaucoma medication in a public health system.

PURPOSE: To analyze the prescribing trends over a 7-years period, between 2013 and 2020, in a tertiary hospital (Hospital Clinico San Carlos, Madrid, Spain) and its health area. MATERIAL AND METHODS: A retrospective study on the data collected from the information systems, "farm@web" and "Farmadrid", of glaucoma prescriptions in the framework of a public health system (Spanish National Health System) during the last seven years. RESULTS: Prostaglandin analogues were the most commonly used drugs in monotherapy during the study period (range: 36.82% - 47.07%). Fixed combinations of topical hypotensives had an upward trend since 2013 (range: 39.99% - 54.21%), becoming the most dispensed drugs in 2020 (48.99%). Preservative-free eye drops (lacking benzalkonium chloride, BAK) have displaced preservative containing topical treatments in all pharmacological groups. In 2013, BAK-preserved eye drops accounted for 91.1% of the total prescriptions, however in 2020 they only accounted for 34.2% of total prescriptions. CONCLUSIONS: The results of the present study highlight the current trend to avoid BAK-preserved eye drops for the treatment of glaucoma.

Basal evaluation and rates of progression based on visual fields in six different glaucoma types of a large population.

PURPOSE: The aim of this study is to analyze the distribution of visual field (VF) mean defect (MD) in six subgroups of glaucoma patients at baseline and follow-up. METHODS: We assessed glaucoma patients treated in a Spanish tertiary care setting with a follow-up of at least 10 months. We have included 1036 visual fields and the following glaucoma subtypes: open-Angle Glaucoma (OAG); Angle-Closure Glaucoma (ACG); Congenital Glaucoma (CG); Ocular hypertension (OHT); Pseudoexfoliative Glaucoma (PSXG); Pigmentary Glaucoma (PG). We have calculated the baseline MD and the progression MD. We have stratified the MD progression in slow (MD rate > -0.5 dB/year); moderate (MD rate between -0.5 and -1 dB/year) fast (MD rate between -1 and -2 dB/year) and catastrophic (<-2 dB/year) progression and their glaucoma subtype. RESULTS: The glaucoma types with the worse baseline MD were CG and PG. We found significant differences after comparing the baseline MD of CG and OAG, ACG, OHT and between PG and OHT. Concerning the MD progression rate: OAG 73.54% showed slow MD progression rate; 9.85% fast; 7.3% moderate and 9.3% catastrophic. ACG 82.22% slow; 8.89% moderate; 2.22% fast and 6.67% catastrophic. CG 68.83% slow; 9.09% fast; 7.79% moderate and 14.29% catastrophic. OHT 88.6% slow; 6.14% moderate; 4.39% fast and 0.88% catastrophic. PSXG 63.24% slow, 13.24% moderate; 8.8% fast and 14.7% catastrophic. PG 89.29% slow; 3.57% moderate and 7.1% fast. CONCLUSIONS: The CG requires special attention because of its aggressive presentation and progression.

Ultraconfined Plasmons in Atomically Thin Crystalline Silver Nanostructures.

The ability to confine light down to atomic scales is critical for the development of applications in optoelectronics and optical sensing as well as for the exploration of nanoscale quantum phenomena. Plasmons in metallic nanostructures with just a few atomic layers in thickness can achieve this type of confinement, although fabrication imperfections down to the subnanometer scale hinder actual developments. Here, narrow plasmons are demonstrated in atomically thin crystalline silver nanostructures fabricated by prepatterning silicon substrates and epitaxially depositing silver films of just a few atomic layers in thickness. Specifically, a silicon wafer is lithographically patterned to introduce on-demand lateral shapes, chemically process the sample to obtain an atomically flat silicon surface, and epitaxially deposit silver to obtain ultrathin crystalline metal films with the designated morphologies. Structures fabricated by following this procedure allow for an unprecedented control over optical field confinement in the near-infrared spectral region, which is here illustrated by the observation of fundamental and higher-order plasmons featuring extreme spatial confinement and high-quality factors that reflect the crystallinity of the metal. The present study constitutes a substantial improvement in the degree of spatial confinement and quality factor that should facilitate the design and exploitation of atomic-scale nanoplasmonic devices for optoelectronics, sensing, and quantum-physics applications.

Improvement of objective ocular redness measured with Keratograph 5M in glaucoma patients after instilling brimonidine drops.

OBJECTIVE: To compare objective ocular redness measured using OCULUS Keratograph 5 M before and after 0.2% brimonidine instillation in glaucoma patients under topical hypotensive treatment. METHODS: 60 eyes from 60 subjects diagnosed with glaucoma or ocular hypertension under hypotensive ocular topical treatment were analyzed. Basal Ophthalmological examination was performed.Outcome variables were OCULUS Keratograph 5 M redness scores (RS) before and after 0.2% brimonidine instillation; overall, bulbar temporal (BT), bulbar nasal (BN), limbar temporal (LT), and limbar nasal (LN); non-invasive average tear film breakup time (Nia-BUT), non-invasive first tear film breakup time (Nif-BUT) and meibography. In addition, the following clinical data were collected: intraocular pressure, type, duration, amount, and preservatives/or not of hypotensive treatment, fluorescein corneal staining score and lower tear meniscus height. RESULTS: All eyes were under topical medication. All redness scores were reduced after brimonidine instillation, mean RS differences were BT 0.82 ± 0.62, BN hyperemia 1.03 ± 0.55, LN hyperemia 0.84 ± 0.49, LT hyperemia 0.71 ± 0.50 and total hyperemia 0.91 ± 0.52 (all p < 0.001). 30 min after brimonidine instillation mean overall RS reduction was 47.97 ± 12.39% (p < 0.001) and after 1 h there was a persistent reduction of overall RS of 45.92 ± 14.27% (p < 0.001). Hyperemia reduction was significant and comparable between preservative and preservative-free group 0.12 ± 0.14 (p > 0.392) and between patient with combination therapy and monotherapy 0.16 ± 0.14 (p > 0.258). CONCLUSION: A significant reduction of conjunctival hyperemia was objectively found in glaucoma patients under topical hypotensive treatment before and after brimonidine instillation. Its fast and long-lasting effect may be useful preoperatively in glaucoma patients to reduce intraoperative bleeding and associated complications.

International Validation of the Immunoscore Biopsy in Patients With Rectal Cancer Managed by a Watch-and-Wait Strategy.

PURPOSE: No biomarker capable of improving selection and monitoring of patients with rectal cancer managed by watch-and-wait (W&W) strategy is currently available. Prognostic performance of the Immunoscore biopsy (ISB) was recently suggested in a preliminary study. METHODS: This international validation study included 249 patients with clinical complete response (cCR) managed by W&W strategy. Intratumoral CD3+ and CD8+ T cells were quantified on pretreatment rectal biopsies by digital pathology and converted to ISB. The primary end point was time to recurrence (TTR; the time from the end of neoadjuvant treatment to the date of local regrowth or distant metastasis). Associations between ISB and outcomes were analyzed by stratified Cox regression adjusted for confounders. Immune status of tumor-draining lymph nodes (n = 161) of 17 additional patients treated by neoadjuvant chemoradiotherapy and surgery was investigated by 3'RNA-Seq and immunofluorescence. RESULTS: Recurrence-free rates at 5 years were 91.3% (82.4%-100.0%), 62.5% (53.2%-73.3%), and 53.1% (42.4%-66.5%) with ISB High, ISB Intermediate, and ISB Low, respectively (hazard ratio [HR; Low v High], 6.51; 95% CI, 1.99 to 21.28; log-rank P = .0004). ISB was also significantly associated with disease-free survival (log-rank P = .0002), and predicted both local regrowth and distant metastasis. In multivariate analysis, ISB was independent of patient age, sex, tumor location, cT stage (T, primary tumor; c, clinical), cN stage (N, regional lymph node; c, clinical), and was the strongest predictor for TTR (HR [ISB High v Low], 6.93; 95% CI, 2.08 to 23.15; P = .0017). The addition of ISB to a clinical-based model significantly improved the prediction of recurrence. Finally, B-cell proliferation and memory in draining lymph nodes was evidenced in the draining lymph nodes of patients with cCR. CONCLUSION: The ISB is validated as a biomarker to predict both local regrowth and distant metastasis, with a gradual scaling of the risk of pejorative outcome.

Local Regrowth and the Risk of Distant Metastases Among Patients Undergoing Watch-and-Wait for Rectal Cancer: What Is the Best Control Group? Multicenter Retrospective Study.

BACKGROUND: A proportion of rectal cancer patients who achieve a clinical complete response may develop local regrowth. Although salvage appears to provide appropriate local control, the risk of distant metastases is less known. OBJECTIVE: To compare the risk of distant metastases between patients who achieve a clinical complete response (watch-and-wait strategy) and subsequent local regrowth and patients managed by surgery after chemoradiation. DESIGN: Retrospective multicenter cohort study. SETTINGS: This study used data of patients from 3 institutions who were treated between 1993 and 2019. PATIENTS: Patients with initial clinical complete response (after neoadjuvant therapy) followed by local regrowth and patients with near-complete pathological response (≤10%) after straightforward surgery after chemoradiation were included. MAIN OUTCOME MEASURES: Univariate and multivariate analyses were performed to identify risk factors for distant metastases. Kaplan-Meier curves were created (log-rank test) to compare survival outcomes. Analyses were performed using time zero as last day of radiation therapy or as date of salvage resection in the local regrowth group. RESULTS: Twenty-one of 79 patients with local regrowth developed distant metastases, whereas only 10 of 74 after upfront total mesorectal excision following neoadjuvant chemoradiation therapy ( p = 0.04). Local regrowth and final pathology (ypT3-4) were the only independent risk factors associated with distant metastases. When using date of salvage resection as time zero, distant metastases-free survival rates were significantly inferior for patients with local regrowth (70% vs 86%; p = 0.01). LIMITATIONS: Small number of patients, many neoadjuvant therapies, and selection bias. CONCLUSIONS: Patients undergoing watch-and-wait strategy who develop local regrowth are at higher risk for development of distant metastases compared to patients with near-complete pathological response managed by upfront surgery after chemoradiation.

NUEVO CRECIMIENTO LOCAL Y EL RIESGO DE METSTASIS A DISTANCIA ENTRE PACIENTES SOMETIDOS A OBSERVACIN Y ESPERA POR CNCER DE RECTO CUL ES EL MEJOR GRUPO DE CONTROL ESTUDIO RETROSPECTIVO MUTICNTRICO: ANTECEDENTES:Una proporción de pacientes que logran una respuesta clínica completa pueden desarrollar un nuevo crecimiento local. Si bien el rescate parece proporcionar un control local apropiado, el riesgo de metástasis a distancia es menos conocido.OBJETIVO:Comparar el riesgo de metástasis a distancia entre los pacientes que logran una respuesta clínica completa (estrategia de observación y espera) y el nuevo crecimiento local posterior con los pacientes tratados con cirugía después de la quimiorradiación.DISEÑO:Estudio de cohorte multicéntrico retrospectivo.CONFIGURACIÓN:Este estudio utilizó datos de pacientes de 3 instituciones que fueron tratados entre 1993 y 2019.PACIENTES:Pacientes con respuesta clínica completa inicial (después de la terapia neoadyuvante) seguida de crecimiento local nuevo y pacientes con respuesta patológica casi completa (≤10 %) después de cirugía directa después de quimiorradiación.PRINCIPALES MEDIDAS DE RESULTADO:Se realizó un análisis univariante/multivariante para identificar los factores de riesgo de metástasis a distancia. Se crearon curvas de Kaplan-Meier (prueba de rango logarítmico) para comparar los resultados de supervivencia. El análisis se realizó utilizando el tiempo cero como último día de radioterapia (1) o como fecha de resección de rescate (2) en el grupo de recrecimiento local.RESULTADOS:Veintiuno de 79 pacientes con recrecimiento local desarrollaron metástasis a distancia, mientras que solo 10 de 74 después de una cirugía sencilla (p = 0,04). El recrecimiento local y la patología final (ypT3-4) fueron los únicos factores de riesgo independientes asociados con las metástasis a distancia. Cuando se utilizó la fecha de la resección de rescate como tiempo cero, las tasas de supervivencia sin metástasis a distancia fueron significativamente inferiores para los pacientes con recrecimiento local (70 frente a 86 %; p = 0,01).LIMITACIONES:Pequeño número de pacientes, muchas terapias neoadyuvantes, sesgo de selección.CONCLUSIONES:Los pacientes sometidos a observación y espera que desarrollan un nuevo crecimiento local tienen un mayor riesgo de desarrollar metástasis a distancia en comparación con los pacientes con una respuesta patológica casi completa manejados con cirugía por adelantado después de la quimiorradiación.

El 100% estaba escolarizado, el 12% tenía apoyo en el colegio y solamente el 4% necesitó acudir a un centro de educación especial. El 68% de las familias recibió apoyo tras el alta hospitalaria. El 56% fue incluido en un programa de atención temprana.Conclusión: la población infantil con EHI tratados con hipotermia presentan secuelas a medio-largo plazo, siendo las más relevantes las alteraciones visuales, las de la integridad de la piel, problemas de eliminación, crisis epilépticas y microcefalia. Se han de potenciar los programas de seguimiento y apoyo tras el alta para poder detectar de forma precoz los signos de alarma, así como para el acompañamiento de sus familias. (AU)

Objective: to describe the Nursing care needs derived of the main consequences in newborns (NBs) diagnosed with hypoxic-ischemic encephalopathy (HIE) and treated with therapeutic hypothermia at the Hospital Universitario Miguel Servet in Zaragoza (Spain).Method: a descriptive cross-sectional study with retrospective data about 32 patients, through clinical record review. The study variables were sociodemographic, clinical (the scale by García-Alix was used to determine the severity of GIE), and Nursing care needs.Results: thirty-two (32) patients were studied; 68.8% were diagnosed with moderate HIE and 31.2% with severe HIE, with 21.9% of death outcomes after treatment. Out of these patients, 31.3% suffered meconium fluid aspiration at the time of delivery; 32% had visual alterations, 20% had alterations in their skin integrity, 16% had elimination problems and epileptic seizures, and 12% presented microcephalia. 100% of them were enrolled in school, 12% had support at school, and only 4% needed to attend a special education centre. Regarding their families, 68% received support after discharge from hospital, and 56% were included in an early care program.Conclusion: the paediatric population with HIE treated with hypothermia presented sequels at medium-long term; the most relevant were visual and skin integrity alterations, elimination problems, epileptic seizures and microcephalia. Programs for follow-up and support after discharge from hospital must be promoted, for an early detection of warning signs, as well as for accompanying their families. (AU)
