Pathological and immunohistochemical assessment of the impact of three different strains of swine enteric coronaviruses in the intestinal barrier.

Swine enteric coronaviruses, such as porcine epidemic diarrhea virus (PEDV) or transmissible gastroenteritis virus (TGEV), have risen concern for the porcine industry and research community due to the increase in their virulence, their potential recombination capacity and the emergence of new variants. This in vivo study aims to compare the impact of three different strains of swine enteric coronaviruses [(two G1b (S-INDEL) PEDV strains and a recombinant TGEV-PEDV or Swine enteric coronavirus (SeCoV)] in the intestine of 3-weeks-old infected piglets, focusing on the pathology and main components of the intestinal barrier, including the number of goblet cells, and the expression of IgA as well as FoxP3, a regulatory T cell marker. Severity of lesions was evidenced in the three infected groups and was highly correlated with the viral load in feces and the frequency of viral antigen-positive cells. Furthermore, higher cellular death together with an increase in the expression of the FoxP3 marker was detected in the duodenum and jejunum of infected animals at 3 days post-infection. Our results highlight a recruitment of FoxP3+ cells in the small intestine of infected animals which may represent a response to the tissue damage caused by viral replication and cell death. Further studies should be addressed to determine the potential role of these cells during swine enteric coronavirus infections.

Estimulación cerebral profunda combinada del núcleo subtalámico y el globo pálido interno en la enfermedad de Parkinson / Combined subthalamic nucleus and globus pallidus internus deep brain stimulation in Parkinson’s disease

Introducción: La estimulación cerebral profunda (ECP) del núcleo subtalámico (NST) y el globo pálido interno (GPi) son los principales abordajes quirúrgicos en la enfermedad de Parkinson avanzada. La estimulación suele aplicarse de forma bilateral en la misma estructura cerebral. Sin embargo, cuando diferentes síntomas motores se presentan concomitantemente en el mismo paciente, la modulación simultánea de diferentes estructuras cerebrales puede ser una alternativa eficaz. Caso clínico: Presentamos un paciente con enfermedad de Parkinson avanzada en el que se realizó ECP combinada en NST y el GPi. La ECP del NST izquierdo controló de manera óptima la sintomatología del hemicuerpo derecho, mientras que las discinesias problemáticas que presentaba en el hemicuerpo izquierdo se redujeron con éxito mediante la estimulación del GPi derecho. Discusión. La estimulación combinada del NST/GPi puede considerarse un enfoque neuroquirúrgico adecuado cuando surge una sintomatología motora desafiante en pacientes con enfermedad de Parkinson avanzada.(AU)

Introduction: Subthalamic nucleus (STN) and globus pallidus internus (GPi) deep brain stimulation (DBS) are the main surgical approaches for advanced Parkinson’s disease. Stimulation is usually applied bilaterally in the same brain structure. However, when various motor symptoms concomitantly present in the same patient, simultaneous modulation of different brain structures may be a suitable alternative. Case report: We present a patient with advanced Parkinson’s disease with a combined DBS neurosurgery. Left STN DBS optimally controlled the off right hemibody symptomatology while left side troublesome dyskinesias were successfully relieved by right GPi stimulation. Discussion: Combined STN/GPi stimulation can be considered a suitable approach when challenging motor symptomatology arises in advanced Parkinson’s disease patients.(AU)

Person-centered strategies for delivering TB diagnostic services in Lima, Peru.

SETTING: Lima, Peru. OBJECTIVE: To close the gap in TB diagnosis, TB diagnostic services must match care-seeking preferences. We sought to identify preferred strategies for delivering TB diagnostic services and to determine whether preferences differ among demographic groups. DESIGN: During May 2022-January 2023, we recruited adults who recently initiated treatment for pulmonary TB. We used an object-case best-worst scaling instrument to assess the desirability of nine hypothetical strategies for delivering TB diagnostic services. A t-test was used to assess differences in preference scores between groups. RESULTS: Among 150 participants, the strategies with the highest preference scores were an integrated mobile unit offering screening for multiple conditions, expedited attention at the health center, and home-based screening. These were strongly preferred by 42%, 25%, and 27% of participants, respectively, and 80% of participants strongly preferred at least one of the three. Expedited attention at the health center scored more highly among people who experienced >2 months delay in TB diagnosis compared to those who experienced a more rapid diagnosis (0.37 ± 0.06 vs. 0.17 ± 0.06; P = 0.031). CONCLUSION: Providing person-centered TB diagnostic services at diverse access points could help reach different populations, which could promote early diagnosis and help close the diagnosis gap.

CONTEXTE: Lima, Pérou. OBJECTIF: Pour combler les lacunes dans le diagnostic de la TB, les services de diagnostic de la TB doivent correspondre aux préférences en matière de recherche de soins. Nous avons cherché à identifier les stratégies préférées pour la prestation de services de diagnostic de la TB et à déterminer si les préférences diffèrent entre les groupes démographiques. MÉTHODE: De mai 2022 à janvier 2023, nous avons recruté des adultes ayant récemment commencé un traitement contre la TB pulmonaire. Nous avons utilisé un instrument d'évaluation du meilleur et du pire pour évaluer la désirabilité de neuf stratégies hypothétiques de prestation de services de diagnostic de la TB. Un test-t a été utilisé pour évaluer les différences dans les scores de préférence entre les groupes. RÉSULTATS: Parmi les 150 participants, les stratégies ayant les scores de préférence les plus élevés étaient une unité mobile intégrée offrant un dépistage pour des conditions multiples, une attention accélérée au centre de santé et un dépistage à domicile. Ces stratégies ont été fortement préférées par 42%, 25% et 27% des participants, respectivement, et 80% des participants ont fortement préféré au moins l'une des trois. L'attention accélérée au centre de santé a obtenu un score plus élevé chez les personnes ayant subi un retard de diagnostic de la TB de plus de 2 mois que chez celles ayant subi un diagnostic plus rapide (0,37 ± 0,06 contre 0,17 ± 0,06 ; P = 0,031). CONCLUSION: La fourniture de services de diagnostic de la TB centrés sur la personne à divers points d'accès pourrait permettre d'atteindre différentes populations, ce qui pourrait favoriser un diagnostic précoce et contribuer à combler le fossé en matière de diagnostic.

Laparoscopic and robotic intracorporeal resection and end-to-end anastomosis in left colectomy: a prospective cohort study - stage 2a IDEAL framework for evaluating surgical innovation.

PURPOSE: To analyze the safety and feasibility of intracorporeal resection and anastomosis in upper rectum, sigmoid, and left colon surgery, via both laparoscopic and robotic approaches. The secondary aim was to assess possible short-term differences between laparoscopic versus robotic surgery. METHODS: A prospective observational cohort study according to IDEAL framework exploration and assessment stage (Development, stage 2a), evaluating and comparing the laparoscopic approach and the robotic approach in left colon, sigmoid, and upper rectum surgery with intracorporeal resection and end-to-end anastomosis. Demographic, preoperative, surgical, and postoperative variables of patients undergoing laparoscopic and robotic surgery are described and compared according to the surgical technique used. RESULTS: Between May 2020 and March 2022, seventy-nine patients were consecutively included in the study, 41 operated via laparoscopy (laparoscopic left colectomy: LLC) and 38 by robotic surgery (robotic left colectomy: RLC). There were no statistically significant differences between the two groups in terms of demographic variables. In surgical variables, the median surgical times differed significantly: 198 min (SD 48 min) for LLC vs. 246 min (SD 72 min) for RLC (p = 0.01, 95% CI: - 75.2 to - 20.5)). The only significant difference regarding postoperative complications was a higher degree of relevant morbidity in the LLC (Clavien-Dindo > II (14.6% vs. 0%, p = 0.03) and Comprehensive Complication Index (IQR 22 vs. IQR 0, p = 0.03). The pathological results were similar in both approaches. CONCLUSION: Laparoscopic and robotic intracorporeal resection and anastomosis are feasible and safe, and obtain similar surgical, postoperative, and pathological results than described in literature. However, morbidity seems to be higher in LLC group with fewer relevant postoperative complications. The results of this study enable us to proceed to stage 2b of the IDEAL framework. CLINICAL TRIAL REGISTRATIONS: The study is registered in Clinical trials with the registration code NCT0445693.

Primary Cutaneous Lymphoma Registry of the Spanish Academy of Dermatology and Venereology (AEDV): Data for the First 5 Years. / Registro de linfomas cutáneos primarios (RELCP) de la AEDV: datos tras 5 años de funcionamiento.

BACKGROUND AND OBJECTIVE: Primary cutaneous lymphomas (PCL) are uncommon. Observations based on the first year of data from the Spanish Registry of Primary Cutaneous Lymphomas (RELCP, in its Spanish abbreviation) of the Spanish Academy of Dermatology and Venereology (AEDV) were published in February 2018. This report covers RELCP data for the first 5 years. PATIENTS AND METHODS: RELCP data were collected prospectively and included diagnosis, treatments, tests, and the current status of patients. We compiled descriptive statistics of the data registered during the first 5 years. RESULTS: Information on 2020 patients treated at 33 Spanish hospitals had been included in the RELCP by December 2021. Fifty-nine percent of the patients were men; the mean age was 62.2 years. The lymphomas were grouped into 4 large diagnostic categories: mycosis fungoides/Sézary syndrome, 1112 patients (55%); primary B-cell cutaneous lymphoma, 547 patients (27.1%); primary CD30+lymphoproliferative disorders, 222 patients (11%), and other T-cell lymphomas, 116 patients (5.8%). Nearly 75% of the tumors were registered in stage I. After treatment, 43.5% achieved complete remission and 27% were stable at the time of writing. Treatments prescribed were topical corticosteroids (1369 [67.8%]), phototherapy (890 patients [44.1%]), surgery (412 patients [20.4%]), and radiotherapy (384 patients [19%]). CONCLUSION: The characteristics of cutaneous lymphomas in Spain are similar to those reported for other series. The large size of the RELCP registry at 5 years has allowed us to give more precise descriptive statistics than in the first year. This registry facilitates the clinical research of the AEDV's lymphoma interest group, which has already published articles based on the RELCP data.

Evaluation of the degradation of the graphene-polypropylene composites of masks in harsh working conditions.

The recent COVID-19 outbreak has led health authorities to recommend at least the use of surgical masks, most preferably respirators (FFP2 or KN95), to prevent the spread of the virus. Non-woven fabrics have been chosen as the best option to manufacture the face masks, due to their filtration efficiency, low cost, and versatility. Modifying the mask filters with graphene has been of great interest due to its potential use as antibacterial and virucidal properties. Indeed, some companies have commercialized face masks in which graphene is coated and/or embedded. However, the Canadian sanitary authorities advised against using the Shandong Shengquan New Materials Co. graphene masks because of the possibility of pulmonary damage produced by graphene inhalation. Thus, we have analyzed the stability of the graphene filter of these masks and compared it with two other commercially available graphene mask filters, evaluating the morphological and spectroscopical change of the fibers, as well as the particles released during the endurance tests. Our work introduces the necessary tools and methodology to evaluate the potential degradation of face masks under extreme working conditions. These methods complement the present standard tests ensuring the security of the new filters based on composites or nanomaterials.

Synchronous enteroid adenocarcinoma at the ureteral implantation site after ureterosigmoidostomy.

Ureterosigmoidostomy is considered to be the oldest urinary diversion technique performed for the first time in the 19th Century in patients with urinary malformations. However, the high rate of complications as well as the significant risk of developing tumors in the colonic portion of the ureteral anastomosis have given rise to other new intestinal urinary diversion techniques. We present the case of a patient with two synchronous enteroid adenocarcinomas, with a latency period of 66 years, at the site of both ureterocolonic anastomoses after ureterosigmoidostomy performed during childhood owing to bladder exstrophy.

Predictive factors of six-week mortality in critically ill patients with SARS-CoV-2: A multicenter prospective study.

OBJECTIVE: The objective of the study is to identify the risk factors associated with mortality at six weeks, especially by analyzing the role of antivirals and munomodulators. DESIGN: Prospective descriptive multicenter cohort study. SETTING: 26 Intensive care units (ICU) from Andalusian region in Spain. PATIENTS OR PARTICIPANTS: Consecutive critically ill patients with confirmed SARS-CoV-2 infection were included from March 8 to May 30. INTERVENTIONS: None. VARIABLES: Variables analyzed were demographic, severity scores and clinical condition. Support therapy, drug and mortality were analyzed. An univariate followed by multivariate Cox regression with propensity score analysis was applied. RESULTS: 495 patients were enrolled, but 73 of them were excluded for incomplete data. Thus, 422 patients were included in the final analysis. Median age was 63 years and 305 (72.3%) were men. ICU mortality: 144/422 34%; 14 days mortality: 81/422 (19.2%); 28 days mortality: 121/422 (28.7%); 6-week mortality 152/422 36.5%. By multivariable Cox proportional analysis, factors independently associated with 42-day mortality were age, APACHE II score, SOFA score at ICU admission >6, Lactate dehydrogenase at ICU admission >470U/L, Use of vasopressors, extrarenal depuration, %lymphocytes 72h post-ICU admission <6.5%, and thrombocytopenia whereas the use of lopinavir/ritonavir was a protective factor. CONCLUSION: Age, APACHE II, SOFA>value of 6 points, along with vasopressor requirements or renal replacement therapy have been identified as predictor factors of mortality at six weeks. Administration of corticosteroids showed no benefits in mortality, as did treatment with tocilizumab. Lopinavir/ritonavir administration is identified as a protective factor.

Long-term outcome predictors after functional remediation in patients with bipolar disorder.

BACKGROUND: Improving functioning in patients with bipolar disorder (BD) is one of the main objectives in clinical practice. Of the few psychosocial interventions that have been specifically developed to enhance the psychosocial outcome in BD, functional remediation (FR) is one which has demonstrated efficacy. The aim of this study was to examine which variables could predict improved functional outcome following the FR intervention in a sample of euthymic or subsyndromal patients with BD. METHODS: A total of 92 euthymic outpatients were included in this longitudinal study, with 62 completers. Partial correlations controlling for the functional outcome at baseline were calculated between demographic, clinical and neurocognitive variables, and functional outcome at endpoint was assessed by means of the Functioning Assessment Short Test scale. Next, a multiple regression analysis was run in order to identify potential predictors of functional outcome at 2-year follow-up, using the variables found to be statistically significant in the correlation analysis and other variables related to functioning as identified in the previous scientific literature. RESULTS: The regression model revealed that only two independent variables significantly contributed to the model (F(6,53): 4.003; p = 0.002), namely verbal memory and inhibitory control. The model accounted for 31.2% of the variance. No other demographic or clinical variable contributed to the model. CONCLUSIONS: Results suggest that patients with better cognitive performance at baseline, especially in terms of verbal memory and executive functions, may present better functional outcomes at long term follow-up after receiving functional remediation.
