Helminth parasites of alien freshwater fishes in Patagonia (Argentina)

A survey of the helminth parasites of alien freshwater fishes from Argentinean Patagonia is presented, based on samples taken from 2010 to 2017 and including previous published records. A total of 1129 fishes were collected, belonging to 11 species from 7 families. We surveyed 34 localities in 12 river basins, and found 43 parasite taxa (15 digeneans, 14 monogeneans, 5 cestodes, 5 nematodes, and 4 acanthocephalans), belonging to 22 families. Data are presented as a parasite/host list with information on host species and localities, site of infection, parasite life–history stage, origin, previous records in Patagonia, and accession numbers to vouchers. The most frequently found helminths were monogeneans and digeneans. Our data suggest that invading fish in Patagonia have transmitted fewer parasite species than they have received by spillback. Twenty–three (53%) of the parasites seem to be acquired by the exotic fishes from native hosts, while 15 helminths were co–introduced along with their exotic fish host and continue to parasitize these alien fish but did not invade native hosts; 4 of these species were introduced with carp, 3 with Cheirodon interruptus, 3 with Corydoras paleatus, 3 with Cnesterodon decemmaculatus, 1 with Oncorhynchus tshawytscha, and 1 with Jenynsia multidentata. The majority of these co–introduced parasites came from the Brazilic ichthyogeographic region (10 species). This is the first review of helminth parasites of alien fishes in Argentina; in total 12 new records of parasites for Argentina, 6 new records of parasites for Patagonia, and 29 new host–parasite records are presented here. This list is far from complete, however, given that some basins in southern Patagonia remain unexplored in terms of parasite detection.Fil: Rauque Perez, Carlos Alejandro.

Impacto en la mortalidad tras la implantación de una red de atención al infarto agudo de miocardio con elevación del segmento ST: Estudio IPHENAMIC

[Abstract] Introduction and objectives: Little is known about the impact of networks for ST-segment elevation myocardial infarction (STEMI) care on the population. The objective of this study was to determine whether the PROGALIAM (Programa Gallego de Atención al Infarto Agudo de Miocardio) improved survival in northern Galicia. Methods: We collected all events coded as STEMI between 2001 and 2013. A total of 6783 patients were identified and divided into 2 groups: pre-PROGALIAM (2001-2005), with 2878 patients, and PROGALIAM (2006-2013), with 3905 patients. Results: In the pre-PROGALIAM period, 5-year adjusted mortality was higher both in the total population (HR, 1.22, 95%CI, 1.14-1.29; P <.001) and in each area (A Coruña: HR, 1.12; 95%CI, 1.02-1.23; P=.02; Lugo: HR, 1.34; 95%CI, 1.2-1.49; P <.001 and Ferrol: HR, 1.23; 95%CI, 1.1-1.4; P=.001). Before PROGALIAM, 5-year adjusted mortality was higher in the areas of Lugo (HR, 1.25; 95%CI, 1.05-1.49; P=.02) and Ferrol (HR, 1.32; 95%CI, 1.13-1.55; P=.001) than in A Coruña. These differences disappeared after the creation of the STEMI network (Lugo vs A Coruña: HR, 0.88; 95%CI, 0.72-1.06; P=.18, Ferrol vs A Coruña: HR, 1.04; 95%CI, 0.89-1.22; P=.58. Conclusions: For patients with STEMI, the creation of PROGALIAM in northern Galicia decreased mortality and increased equity in terms of survival both overall and in each of the areas where it was implemented. This study was registered at ClinicalTrials.gov (Identifier: NCT02501070).[Resumen] Introducción y objetivos. Se sabe muy poco del impacto que las redes de atención del infarto agudo de miocardio con elevación del segmento ST (IAMCEST) tienen en la población. El objetivo de este estudio es averiguar si el PROGALIAM (Programa Gallego de Atención al Infarto Agudo de Miocardio) mejoró la supervivencia en la zona norte de Galicia. Métodos. Se recogieron todos los eventos codificados como IAMCEST entre 2001 y 2013. Se identificó a 6.783 pacientes, divididos en 2 grupos: pre-PROGALIAM (2001-2005), 2.878 pacientes, y PROGALIAM (2006-2013), 3.905 pacientes. Resultados. En la etapa pre-PROGALIAM, la mortalidad ajustada a 5 años fue superior tanto en la población total (HR = 1,22; IC95%, 1,14-1,29; p < 0,001), como en cada una de las áreas (A Coruña, HR = 1,12; IC95%, 1,02-1,23; p = 0,02; Lugo, HR = 1,34; IC95%, 1,2-1,49; p < 0,001, y Ferrol, HR = 1,23; IC95%, 1,1-1,4; p = 0,001). Antes del PROGALIAM, la mortalidad a 5 años en las áreas de Lugo (HR = 0,8; IC95%, 0,67-0,95; p = 0,02) y Ferrol (HR = 0,75; IC95%, 0,64-0,88; p = 0,001) era superior que en A Coruña. Estas diferencias desaparecieron tras el desarrollo de la red (Lugo comparado con A Coruña, HR = 0,88; IC95%, 0,72-1,06; p = 0,18; Ferrol comparado con A Coruña, HR = 1,04; IC95%, 0,89-1,22; p = 0,58. Conclusiones. El desarrollo del PROGALIAM en el área norte de Galicia disminuyó la mortalidad e incrementó la equidad de los pacientes con IAMCEST tanto en general como en cada una de las áreas donde se implantó.

Acondicionamiento de garbanzo (Cicer arientium) por el proceso de nixtamalización para la obtención de harina utilizada en la elaboración de pan de caja

Objective: The aim was to establish the effect on quality characteristics of loaf bread added with chickpea flour obtained by nixtamalization and soaking processes. Design/methodology/approach: The nixtamalization process was realized using 2% Ca(OH)2 solution, 3:1 (w/v) with respect to the grain, and cooking for 80 min. After 14 h, the nixtamal was washing three times. Nixtamalized grains were dried, milled and sieved (U.S. 35 mesh). The flour obtained by the soaking method (12 h, T=21 °C), was cooked (95 °C, 45 min), drying (48 h, 48 °C) and milling. The characterization of colour and ashes was determined on the flour and bread, also physical, quality and sensorial characteristics were measured. Results: The results demonstrated that substitution with 35% of nixtamalized chickpea flour, showed the best quality on physical and nutritional characteristics according with the reference (hardness: 23.6 ± 3 and 20.8 ± 6.2 N, color (C): 28.4 ± 1.37 and 29.2 ± 0.927, ashes: 0.17 and 1.43%, respectively). Limitations on study/implications: Results of sensory analysis of bread obtained by the soaking method has shown that the colour and flavour characteristics were not desired. Findings/conclusions: The information obtained demonstrates that this process has a positive impact for the consumer, increasing the availability of some nutrients.Objetivo: Establecer el efecto en las características de calidad de pan de caja elaborado con harina de garbanzo (Cicer arientium L.) obtenida por nixtamalización y remojo.

Después de 14 h, el nixtamal se lavó tres veces. Los granos nixtamalizados se secaron, molieron y tamizaron (U.S. 35 mesh). Para el método de remojo (12 h, T = 21 ° C), el garbanzo se coció (95 °C, 45 min), se secó (48 h, 48 ° C) y se molió. Se determinó el color y cenizas en la harina y el pan, también se midieron las características físicas, de calidad y señoriales de este último. Resultados: Los resultados mostraron que el pan sustituido con 35% de harina de garbanzo nixtamalizado, presentó las mejores características de calidad, físicas y nutrimentales con respecto al testigo (dureza: 23.6±3 y 20.8±6.2 N, color (C): 28.41±1.368 y 29.23±0.927, cenizas: 0.17 y 1.43% respectivamente). Limitaciones del estudio/implicaciones: La evaluación sensorial del pan elaborado con harina de garbanzo obtenida por remojo indicó que estos presentaban sabor más intenso así como color no característico, que desagrado a los jueces. Hallazgos/conclusiones: Los resultados tienen un impacto positivo para el consumidor, incrementando la disponibilidad de algunos nutrientes

Performance of standardised colposcopy to detect cervical precancer and cancer for triage of women testing positive for human papillomavirus : results from the ESTAMPA multicentric screening study

Correspondence to: Dr Joan Valls, Early Detection, Prevention and Infections Branch, International Agency for Research on Cancer, Lyon 69366, France. [email protected]. Colposcopy, currently included in WHO recommendations as an option to triage human papillomavirus (HPV)-positive women, remains as the reference standard to guide both biopsy for confirmation of cervical precancer and cancer and treatment approaches. We aim to evaluate the performance of colposcopy to detect cervical precancer and cancer for triage in HPV-positive women. Methods. This cross-sectional, multicentric screening study was conducted at 12 centres (including primary and secondary care centres, hospitals, laboratories, and universities) in Latin America (Argentina, Bolivia, Colombia, Costa Rica, Honduras, Mexico, Paraguay, Peru, and Uruguay). Eligible women were aged 30–64 years, sexually active, did not have a history of cervical cancer or treatment for cervical precancer or a hysterectomy, and were not planning to move outside of the study area. Women were screened with HPV DNA testing and cytology. HPV-positive women were referred to colposcopy using a standardised protocol, including biopsy collection of observed lesions, endocervical sampling for transformation zone (TZ) type 3, and treatment as needed. Women with initial normal colposcopy or no high-grade cervical lesions on histology (less than cervical intraepithelial neoplasia [CIN] grade 2) were recalled after 18 months for another HPV test to complete disease ascertainment; HPV-positive women were referred for a second colposcopy with biopsy and treatment as needed. Diagnostic accuracy of colposcopy was assessed by considering a positive test result when the colposcopic impression at the initial colposcopy was positive minor, positive major, or suspected cancer, and was considered negative otherwise. The main study outcome was histologically confirmed CIN3+ (defined as grade 3 or worse) detected at the initial visit or 18-month visit. Findings. Between Dec 12, 2012, and Dec 3, 2021, 42 502 women were recruited, and 5985 (14·1%) tested positive for HPV. 4499 participants with complete disease ascertainment and follow-up were included in the analysis, with a median age of 40·6 years (IQR 34·7–49·9). CIN3+ was detected in 669 (14·9%) of 4499 women at the initial visit or 18-month visit (3530 [78·5%] negative or CIN1, 300 [6·7%] CIN2, 616 [13·7%] CIN3, and 53 [1·2%] cancers). Sensitivity was 91·2% (95% CI 88·9–93·2) for CIN3+, whereas specificity was 50·1% (48·5–51·8) for less than CIN2 and 47·1% (45·5–48·7) for less than CIN3. Sensitivity for CIN3+ significantly decreased in older women (93·5% [95% CI 91·3–95·3] in those aged 30–49 years vs 77·6% [68·6–85·0] in those aged 50–65 years; p<0·0001), whereas specificity for less than CIN2 significantly increased (45·7% [43·8–47·6] vs 61·8% [58·7–64·8]; p<0·0001). Sensitivity for CIN3+ was also significantly lower in women with negative cytology than in those with abnormal cytology (p<0·0001). Interpretation. Colposcopy is accurate for CIN3+ detection in HPV-positive women. These results reflect ESTAMPA efforts in an 18-month follow-up strategy to maximise disease detection with an internationally validated clinical management protocol and regular training, including quality improvement practices. We showed that colposcopy can be optimised with proper standardisation to be used as triage in HPV-positive women.Consejo Nacional de Ciencia y TecnologíaPrograma Paraguayo para el Desarrollo de la Ciencia y Tecnología.

Economic evaluation of complete revascularization versus stress echocardiography-guided revascularization in the STEACS with multivessel disease

[Resumen] Introducción y objetivos. Los estudios económicos pueden ayudar a tomar decisiones en el tratamiento de la enfermedad multivaso en el infarto. Se planteó realizar una evaluación económica del ensayo clínico CROSS-AMI (Complete Revascularization or Stress Echocardiography in Patients With Multivessel Disease and ST-Segment Elevation Acute Myocardial Infarction). Métodos. Se realizó un análisis de comparación de costes económicos de las estrategias (revascularización angiográfica completa [RCom] y revascularización selectiva guiada por isquemia en ecocardiograma de estrés [RSel]) comparadas en el ensayo clínico CROSS-AMI (N = 306), derivados de la hospitalización inicial y del primer año de seguimiento, según las tarifas oficiales vigentes en nuestro sistema de salud. Resultados. El coste de la hospitalización inicial resultó superior en el grupo de RCom que en la rama de RSel (19.657,9 ± 6.236,8 frente a 14.038,7 ± 4.958,5 euros; p < 0,001). No hubo diferencias entre ambos grupos en el coste del primer año de seguimiento (RCom, 2.423,5 ± 4.568,0 euros; Rsel, 2.653,9 ± 5.709,1 euros; p = 0,697). El coste total fue 22.081,3 ± 7.505,6 euros en la rama de RCom y 16.692,6 ± 7.669,9 euros en la rama de RSel (p < 0,001). Conclusiones. En el ensayo clínico CROSS-AMI, el sobrecoste inicial de la RCom frente a la RSel no se vio compensado por un ahorro significativo en el seguimiento. La RSel parece ser una estrategia más eficiente que la RCom para los pacientes con síndrome coronario agudo con elevación del segmento ST y enfermedad multivaso tratados mediante angioplastia emergente.[Abstract] Introduction and objectives. Economic studies may help decision making in the management of multivessel disease in the setting of myocardial infarction. We sought to perform an economic evaluation of CROSS-AMI (Complete Revascularization or Stress Echocardiography in Patients With Multivessel Disease and ST-Segment Elevation Acute Myocardial Infarction) randomized clinical trial. Methods. We performed a cost minimization analysis for the strategies (complete angiographic revascularization [ComR] and selective stress echocardiography–guided revascularization [SelR]) compared in the CROSS-AMI clinical trial (N = 306), attributable the initial hospitalization and readmissions during the first year of follow-up, using current rates for health services provided by our health system. Results. The index hospitalization costs were higher in the ComR group than in SelR arm (19 657.9 ± 6236.8 € vs 14 038.7 ± 4958.5 €; P < .001). There were no differences in the costs of the first year of follow-up rehospitalizations between both groups for (ComR 2423.5 ± 4568.0 vs SelR 2653.9 ± 5709.1; P = .697). Total cost was 22 081.3 ± 7505.6 for the ComR arm and 16 692.6 ± 7669.9 for the SelR group (P < .001). Conclusions. In the CROSS-AMI trial, the initial extra economic costs of the ComR versus SelR were not offset by significant savings during follow-up. SelR seems to be more efficient than ComR in patients with ST-segment elevation acute coronary syndrome and multivessel disease treated by emergent angioplasty

Multicentric study of cervical cancer screening with human papillomavirus testing and assessment of triage methods in Latin America : the ESTAMPA screening study protocol

Q1Q1Introduction Human papillomavirus (HPV) testing is replacing cytology in primary screening. Its limited specificity demands using a second (triage) test to better identify women at high-risk of cervical disease. Cytology represents the immediate triage but its low sensitivity might hamper HPV testing sensitivity, particularly in low-income and middle-income countries (LMICs), where cytology performance has been suboptimal. The ESTAMPA (EStudio multicéntrico de TAMizaje y triaje de cáncer de cuello uterino con pruebas del virus del PApiloma humano; Spanish acronym) study will: (1) evaluate the performance of different triage techniques to detect cervical precancer and (2) inform on how to implement HPV-based screening programmes in LMIC. Methods and analysis Women aged 30–64 years are screened with HPV testing and Pap across 12 study centres in Latin America. Screened positives have colposcopy with biopsy and treatment of lesions. Women with no evident disease are recalled 18 months later for another HPV test; those HPV-positive undergo colposcopy with biopsy and treatment as needed. Biological specimens are collected in different visits for triage testing, which is not used for clinical management. The study outcome is histological high-grade squamous intraepithelial or worse lesions (HSIL+) under the lower anogenital squamous terminology. About 50 000 women will be screened and 500 HSIL+ cases detected (at initial and 18 months screening). Performance measures (sensitivity, specificity and predictive values) of triage techniques to detect HSIL+ will be estimated and compared with adjustment by age and study centre. Ethics and dissemination The study protocol has been approved by the Ethics Committee of the International Agency for Research on Cancer (IARC), of the Pan American Health Organisation (PAHO) and by those in each participating centre. A Data and Safety Monitoring Board (DSMB) has been established to monitor progress of the study, assure participant safety, advice on scientific conduct and analysis and suggest protocol improvements. Study findings will be published in peer-reviewed journals and presented at scientific meetings. Trial registration number NCT01881659Revista Internacional - Indexad

Aportaciones a los estudios económico-administrativos. Reflexiones teóricas y evidencias empíricas

La economía y la administración están inmersas en el universo de las ciencias sociales, áreas del conocimiento que comprenden dominios diferentes, pero también convergen y se intersectan en un objeto de estudio: las organizacienones y sus agregados (industrias o sectores). Desde una perspectiva social, los estudios económico-administrativos informan sobre cómo hacer eficientes a las organizaciones y competitivos a los sectores con la finalidad de impactar positivamente en la justicia social (por ejemplo: mediante productos de mejor calidad a mejores precios). El auge de este tipo de estudios está extendido a fenómenos clave en el mundo de hoy, tales como: la ventaja competitiva, la innovación, la administración de la cadena de suministros y la administración verde, entre otros.El objetivo de este libro es difundir las aportaciones hechas a los estudios económico-administrativos, ya sea como reflexiones teóricas o a modo de evidencia empírica, pues la conjunción de varias ciencias ayuda a comprender fenómenos complejos mejor que una disciplina en forma aislada. Más que la homogeneidad de teorías o hegemonía de unas sobre otras, la investigación interdisciplinaria construye un acercamiento a la diversidad de puntos de vista: se buscan factores, métodos o lenguajes comunes alrededor de un objeto de estudio (Fernández, 2009; Martínez, 1997), llegándose a conformar una comunidad científica con antecedentes disciplinarios diferentes, pero con cierta unidad, relaciones y acciones recíprocas (Kuhn, 1995). Así, en este texto el objeto de estudio es el funcionamiento e interacción de las organizaciones, como integrantes de los sectores económicos, en los mercados locales y globales. La comunidad científica está conformada por investigadores y egresados del Doctorado en Ciencias Económico-Administrativas, el cual nace en 2006 en la Universidad Autónoma del Estado de México, a cargo de la Dependencia de Educación Superior (DES) Económico-Administrativa

Long-Term Real-World Effectiveness and Safety of Ustekinumab in Crohn’s Disease Patients: The SUSTAIN Study

Background Large real-world-evidence studies are required to confirm the durability of response, effectiveness, and safety of ustekinumab in Crohn’s disease (CD) patients in real-world clinical practice. Methods A retrospective, multicentre study was conducted in Spain in patients with active CD who had received ≥1 intravenous dose of ustekinumab for ≥6 months. Primary outcome was ustekinumab retention rate; secondary outcomes were to identify predictive factors for drug retention, short-term remission (week 16), loss of response and predictive factors for short-term efficacy and loss of response, and ustekinumab safety. Results A total of 463 patients were included. Mean baseline Harvey-Bradshaw Index was 8.4. A total of 447 (96.5%) patients had received prior biologic therapy, 141 (30.5%) of whom had received ≥3 agents. In addition, 35.2% received concomitant immunosuppressants, and 47.1% had ≥1 abdominal surgery. At week 16, 56% had remission, 70% had response, and 26.1% required dose escalation or intensification; of these, 24.8% did not subsequently reduce dose. After a median follow-up of 15 months, 356 (77%) patients continued treatment. The incidence rate of ustekinumab discontinuation was 18% per patient-year of follow-up. Previous intestinal surgery and concomitant steroid treatment were associated with higher risk of ustekinumab discontinuation, while a maintenance schedule every 12 weeks had a lower risk; neither concomitant immunosuppressants nor the number of previous biologics were associated with ustekinumab discontinuation risk. Fifty adverse events were reported in 39 (8.4%) patients; 4 of them were severe (2 infections, 1 malignancy, and 1 fever). Conclusions Ustekinumab is effective and safe as short- and long-term treatment in a refractory cohort of CD patients in real-world clinical practice

Using Interpretable Machine Learning to Identify Baseline Predictive Factors of Remission and Drug Durability in Crohn’s Disease Patients on Ustekinumab

Ustekinumab has shown efficacy in Crohn's Disease (CD) patients. To identify patient profiles of those who benefit the most from this treatment would help to position this drug in the therapeutic paradigm of CD and generate hypotheses for future trials. The objective of this analysis was to determine whether baseline patient characteristics are predictive of remission and the drug durability of ustekinumab, and whether its positioning with respect to prior use of biologics has a significant effect after correcting for disease severity and phenotype at baseline using interpretable machine learning. Patients' data from SUSTAIN, a retrospective multicenter single-arm cohort study, were used. Disease phenotype, baseline laboratory data, and prior treatment characteristics were documented. Clinical remission was defined as the Harvey Bradshaw Index <= 4 and was tracked longitudinally. Drug durability was defined as the time until a patient discontinued treatment. A total of 439 participants from 60 centers were included and a total of 20 baseline covariates considered. Less exposure to previous biologics had a positive effect on remission, even after controlling for baseline disease severity using a non-linear, additive, multivariable model. Additionally, age, body mass index, and fecal calprotectin at baseline were found to be statistically significant as independent negative risk factors for both remission and drug survival, with further risk factors identified for remission
