Hábitos alimentarios de la Corvina Cilus gilberti (ABBOTT, 1889) (PISCES: SCIAENIDAE) frente a la costa de Talcahuano.
Authors: Chong J. , Cortés N. , Bustos R.
Published: March 2024

La corvina o corvinilla Cilus gilberti (Abbott, 1889), es un pez de hábitos pelágicos que se distribuye en Chile desde Arica por el norte (18°20'S) hasta Chiloé (43°06'S) asociado a sectores costeros de fondos blandos. A pesar del gran interés pesquero por esta especie, especialmente para el sector artesanal, existen muy pocos antecedentes sobre aspectos básicos de su biología. En el presente trabajo se analizó la dieta de 827 ejemplares, provenientes de la zona pesquera comprendida entre Pta. Pingueral (36°30') y el Golfo

de Arauco (37°13'S) desde agosto de 1994 a julio de 1995. El comportamiento trófico de C. gilberti se analizó cualitativamente y cuantitativamente considerando la talla de los ejemplares y la variación estacional. Se determinó que la corvina preda ocasionalmente sobre un gran número de presas, pero que en términos de importancia relativa, la dieta esta reducida a un estrecho espectro trófico, dado que se alimenta preferentemente de pequeños crustáceos (Mysidacea y Eufausiacea) y peces (anchovetas y sardinas). Los resultados señalan que habría un cambio en la dieta a través del desarrollo ontogenético de las corvinas desde los individuos más pequeños, que presentan hábitos preferentemente carcinófagos hasta los ejemplares más grandes donde la carcinofagia se mantiene en igual proporción que la ictiofagia. La variación estacional está determinada exclusivamente durante el período de invierno en relación a las otras estaciones donde se produce un cambio específico en la dieta de los individuos.
Cuarenta años de Biología Pesquera: fin de un ciclo e inicio de uno nuevo para las publicaciones Chilenas en Ciencias del Mar. DE UN CICLO E INICIO DE UNO NUEVO PARA LAS PUBLICACIONES CHILENAS EN CIENCIAS DEL MAR
Authors: Camus Patricio A.
Published: March 2024

La revista Biología Pesquera cumple 40 años de existencia dedicados a servir a los investigadores en ciencias del mar. Biología Pesquera ha logrado mantenerse hasta hoy pese a las dificultades para sostener la continuidad de las revistas científicas chilenas, lo cual se refleja sin duda en su historia un tanto heterogénea. El primer número de la revista fue publicado en Octubre de 1961, en un esfuerzo conjunto de la Estación de Biología Marina de la Universidad de Chile y el Departamento de Pesca y Caza del Ministerio de Agricultura. No obstante, ya su segundo número, publicado en 1967, era auspiciado sólo por la Sección de Estudios Biológicos del Departamento de Pesca y Caza, mientras el número 3, publicado en 1968, había pasado a la División de Pesca del Servicio Agrícola y Ganadero (SAG). Para los números posteriores, la División de Pesca se había transformado en División de Protección Pesquera, aunque manteniendo la tutela del SAG, y más tarde en el Servicio Nacional de Pesca de Chile, que publicó hasta el número 12 en 1979. Posteriormente, la revista fue transferida a la Pontificia Universidad Católica de Chile publicándose el número 13 en 1984, en forma conjunta por los Departamentos de Biología y Tecnología del Mar (de la sede Talcahuano) y de Biología Ambiental y Poblaciones (Santiago). Esta etapa duró hasta 1990, cuando a partir del número 20 de 1991, la publicación de Biología Pesquera quedó a cargo de la Facultad de Ciencias de la Universidad Católica de la Santísima Concepción.
Histamina determinada por fluorometría en harina de pescado y la materia prima sometida a diferentes temperaturas.
Authors: Muñoz B. Christian , Herrera C. Carlos
Published: March 2024

Se optimizó un método fluorométrico para determinar la concentración de histamina en harinas de pescado, el método incluye etapas de extracción en metanol, purificación con una resina de intercambio iónico, reacción de fluorescencia con o-ftaldialdehido y lectura en fluorómetro. Se observó un comportamiento lineal para concentraciones de histamina que oscilan entre 0,1 y 15 pg/5mL y una excelente selectividad de histamina frente a otras aminas biogénicas. Por otro lado, se evaluó las características de recuperación que presenta la resina, la que se cuantificó utilizando soluciones estándares de aminas biogénicas y muestras de harina de jurel Trachurus symmetricus murphyi, (Nichols, 1920) que fueron eluídas a través de la resina para su cuantificación en el fluorómetro. Se registraron recuperaciones de un 100% para concentraciones inferiores a 350 mg/Kg de histamina, y recuperaciones de 85 a 90% para concentraciones superiores. Posteriormente se analizaron muestras de harina de jurel y los resultados se compararon con los entregados por laboratorios de certificación externos a fin de evaluar la correlación entre los respectivosvalores. Los resultados de correlación no mostraron diferencias significativas (p=0,05), sin embargo los valores obtenidos por el método fluorométrico fueron algo más bajos que los de HPLC, debido posiblemente a una retención de la histamina en la etapa de purificación por la resina. Finalmente el método fluorométrico fue aplicado al estudio del efecto de la temperatura de almacenamiento, sobre la materia prima antes de reducción a harina.

Authors: Tapiero Anibal L. , Guevara Yudy Alejandra
Published: March 2024

El caucho natural (Hevea brasiliensis), tiene limitantes económicos importantes ocasionados por la incidencia de plagas y enfermedades. Entre estas últimas se destaca el Mal Suramericano de las Hojas (SALB por sus siglas en inglés) y Caída de las Hojas o Antracnosis por Colletotrichum spp., con diferente nivel de incidencia y severidad en varias zonas. El área sembrada en Colombia cuenta con aproximadamente 65.000 Ha (Censo Nacional Cauchero, 2016 citado por MINISTERIO de AGRICULTURA y DESARROLLO RURAL, 2016), distribuidas en 5 núcleos productivos. Parte del área se encuentra en Zona de escape al SALB con restricciones menores, en su mayor proporción con RRIM 600. En Zona de no-escape predomina el cultivo de clones brasileros (FX 3864 y FX 4098). Ante la reducida diversidad genética, particularmente en la Orinoquia (con aproximadamente 55% del total de caucho y más del 85% del área con RRIM 600) se planteó la necesidad de determinar y proponer programas de manejo integrado que permitan reducir los riesgos de pérdida económica ocasionados por la incidencia de enfermedades. Para el efecto se propuso determinar y analizar la importancia relativa de componentes de los 2 elementos cuya conjunción resultan en la ocurrencia y desarrollo de una epidemia: “potencialidad epidémica y condiciones ambientales favorables”, de los patosistemas más importantes en 4 núcleos del cultivo y establecer el modelo epidemiológico de las enfermedades de importancia económica de las enfermedades del caucho en Colombia.
Health Care Workers’ Expectations of the Mercury Advance SMARTcare Solution to Prevent Pressure Injuries: Individual and Focus Group Interview Study
Authors: Slob Joeri , van Houwelingen Thijs , Kort Helianthe S M
Published: March 2024

Background

The transformation in global demography and the shortage of health care workers require innovation and efficiency in the field of health care. Digital technology can help improve the efficiency of health care. The Mercury Advance SMARTcare solution is an example of digital technology. The system is connected to a hybrid mattress and is able to detect patient movement, based on which the air pump either starts automatically or sends a notification to the app. Barriers to the adoption of the system are unknown, and it is unclear if the solution will be able to support health care workers in their work.

Objective

This study aims to gain insight into health care workers’ expectations of factors that could either hamper or support the adoption of the Mercury Advance SMARTcare unit connected to a Mercury Advance mattress to help prevent patients from developing pressure injuries in hospitals and long-term care facilities.

Methods

We conducted a generic qualitative study from February to December 2022. Interviews were conducted, and a focus group was established using an interview guide of health care workers from both the United Kingdom and the Netherlands. Thematic analysis was performed by 2 independent researchers.

Results

A total of 14 participants took part in the study: 6 (43%) participants joined the focus group, and 8 (57%) participants took part in the individual interviews. We identified 13 factors based on four themes: (1) factors specifically related to SMARTresponse, (2) vision on innovation, (3) match with health care activities, and (4) materials and resources involved. Signaling function, SMARTresponse as prevention, patient category, representatives, and implementation strategy were identified as facilitators. Perception of patient repositioning, accessibility to pressure injury aids, and connectivity were identified as barriers.

Conclusions

Several conditions must be met to enhance the adoption of the Mercury Advance SMARTcare solution, including the engagement of representatives during training and a reliable wireless network. The identified factors can be used to facilitate the implementation process.
Getting to Know Your Patient: Content Analysis of Patients’ Answers to a Questionnaire for Promoting Person-Centered Care
Authors: Bergers Juno HK , Wessels-Wynia Hester , Seute Tatjana , Janssens Astrid , van Delden Johannes JM
Published: March 2024

Background

Person-centered care (PCC) encourages patients to actively participate in health care, thus facilitating care that fits the life of the patient. Therefore, health care professionals (HCPs) need to know the patient. As part of a broad policy for improving PCC, a digital questionnaire (“We would like to know you”) consisting of 5 questions has previously been developed to help HCPs to get to know the patient with the help of patient and staff involvement.

Objective

The purpose of this study was to provide insight into the content and aims of the questionnaire to understand its potential and usability.

Methods

We conducted a qualitative, retrospective content analysis of patients’ answers using NVivo Pro (QSR International). The questionnaire was used in the outpatient neuro-oncology department of a Dutch academic hospital.

Results

Of 374 invited patients, 78 (20.9%) completed the questionnaire. We selected a sample of 42 (54%) of the 78 patients. Patients used a median of 16 (IQR 7-27) words per question, and most answers were easily interpretable. When asked about important activities, social activities, sports, or maintaining a normal life were most frequently mentioned. Patients wrote about fear of the disease, its possible influence on life, or fear of the future in general. Patients wanted HCPs to know about their care and communication preferences or shared personal information. They formulated expectations about effective treatment, communication, and the care process.

Conclusions

The questionnaire seems usable because patients provide interpretable answers that take little time to read, which HCPs can use to personalize care. Our study shows the potential of the questionnaire to help deliver PCC.

Published: March 2024

BACKGROUND

The influence of exercise deception and immersive virtual reality on ratings of perceived exertion and heart rate during exercise have been studied in isolation, but rarely in tandem. Given that there is evidence to suggest that both factors can affect perceived exertion and heart rate during exercise, addressing the gap in knowledge pertaining to such influences is imperative.

OBJECTIVE

This study investigated the influence of speed deception on heart rate and ratings of perceived exertion (RPE) during immersive virtual reality (IVR) while walking on a treadmill.

METHODS

Using a double-blinded, crossover research design, sixteen college-aged adults (eight females) were randomly assigned a testing order for a total of six, ten-minute trials of treadmill walking; three trials conducted with IVR on one day and three non-IVR trials (i.e. control) on another day at 3.3, 3.5, and 3.7 mph. A 24 hour washout period was given in between the first and second day of testing. Participants were told that all trials occurred at 3.5 mph. Borg RPE scores were assessed after each trial while HR was monitored throughout.

RESULTS

The IVR trials produced lower mean RPE scores in comparison to the non-IVR trials during 3.5 and 3.7 mph (p = 0.002, 95% CI: (0.6, 1.8); p = 0.002, 95% CI (1.2, 2.7), respectively). The IVR trials also yielded a lower mean HR compared to the non-IVR trials at the highest speed of 3.7 mph (p = 0.049, 95% CI: (2.0, 12.7)). Within group differences for the non-IVR group were identified in RPE for the 3.3 and 3.5 mph trials compared to those at 3.7 mph (p = 0.002, 95% CI: (-1.4, -0.5); p = 0.002, 95% CI: (-1.4, -0.5), respectively). No differences were detected within the IVR group.

CONCLUSIONS

These findings suggest that using deception via an immersive virtual reality exergaming experience may affect attenuated participant perceived effort and heart rate response without the user noticing the effect.

Published: March 2024

Objective: To compare the efficacy and safety of topical ciprofloxacin v/s fortified gentamicin-ceftazidime in bacterial keratitis.
Methods: This was a randomized control trial done on 60 subjects with 30 subjects in each group. The clinical signs and symptoms are recorded in two groups of bacterial keratitis patients at baseline and after 2 w of treatment using ciprofloxacin ophthalmic solution and standard therapy regimen of fortified gentamicin-ceftazidime using scoring of ocular signs and symptoms (1=minimum, not present), (5=maximum, severe) with a study period of 3 mo
Results: The group administered with fortified ceftazidime+gentamicin demonstrated superior clinical and statistical efficacy compared to ciprofloxacin in treating bacterial keratitis. This regimen led to a substantial alleviation of symptoms and minimized ocular discomfort to a greater extent. Notably, the calculated p-value for the day 14 score, standing at 0.02 (below the 0.05 threshold), underscores the significant superiority of fortified ceftazidime+gentamicin in symptom reduction.
Conclusion: We conclude that fortified ceftazidime+gentamicin is better than ciprofloxacin for the treatment of bacterial keratitis.

Published: March 2024

Objective: Pemphigus Vulgaris [PV] is a chronic autoimmune disease. Corticosteroids and Immunosuppressants are the main line of treatment. The aim of this study was to evaluate the prescription pattern and patient adherence behavior with therapy. We determined the association between patient adherence and quality of life in patients with pemphigus vulgaris.
Methods: A prospective observational study was conducted from February 2020 to May 2021. The age and sex of patients who were diagnosed with PV within 1 mo period and confirmative histopathological findings in Biopsy were included in the study. A total of 35 patients were analyzed and patients were reviewed for medication adherence and quality of life by using MMAS-8 and WHOQOL respectively, monthly till 3 mo after initiation of therapy. Statistical analysis was done by using Epi Info version 7.1.5.
Results: Out of 140 prescriptions, vitamin C and zinc were the most common drug prescribed in 129 prescriptions followed by prednisolone prescribed in 128 prescriptions. The average number of drugs per encounter was 8.67. 97.56 % of drugs were prescribed by generic names. No significant improvement was seen in the adherence behavior of patients from 1st follow-up to 3rd follow-up. It was observed that physical, psychological, and environmental domains have significant associations with medication adherence in all 3 follow-up visits.
Conclusion: It was concluded that Polypharmacy and inappropriate use of medicines may decrease the adherence behavior of patients to the therapy. Low adherence to pharmacotherapy affects the quality of life in PV patients. This study is beneficial for raising awareness about treatment adherence and also encouraging the development of appropriate interventions.

Guidelines for Winter Recreation near Wolverine Dens in Montane Western North America
Authors: Hausleitner Doris , Kortello Andrea , Barrueto Mirjam , Harrower William , Krebs John
Published: March 2024

Wolverine den in snowy areas with boulders or woody debris at or below tree line in montane western North America. They have naturally low reproductive rates, a fidelity to denning areas, and a sensitivity to human presence during denning. The goal was to synthesize existing ecological information for denning wolverine and identify risks from human presence in the categories of timing, distance, footprint, pattern of use, and frequency of use. The authors suggest commercial tenure holders and private users keep recreation in the low-risk category to minimize disturbance on denning females. Denning area surveys should be conducted prior to tenure application or renewals and dens can be identified by a concentration of tracks over more than three weeks from January 15 to May 15. Recreation should be restricted within a 5-km radius of confirmed dens during this window. Best practices include limiting the number of groups and concentrating movement on existing linear features as wolverine are sensitive to disturbance at a very low intensity of use and are at greatest risk when disturbances are dispersed and unpredictable.
Fire performance of Pinus taeda wood treated with zinc borate before and after leaching
Authors: Camargo Alvaro , Ibáñez Claudia Marcela
Published: March 2024

Owing to its physico-mechanical properties, wood is widely used in housing for both outdoor structures and indoors in floors, ceilings and others. However, its vulnerability to fire makes protection necessary for occupant safety and damage prevention. In this study, the fire performance of Pinus taeda (loblolly pine) wood from northeastern Uruguay treated with zinc borate  synthetized in our laboratory is tested. The effect of leaching on zinc borate fire retardant properties was also evaluated. The following parameters associated with the thermal degradation process of wood were analyzed: flame spread, carbonized area, carbonization index and mass loss. The wood was radially and tangentially exposed to the flame in a Vandersall tunnel under controlled conditions for three exposure times: 30, 60, and 80 seconds. The micromorphology of the surfaces exposed to the flame at each exposure time was analyzed with a scanning electron microscope in order to evaluate fiber damage, zinc borate distribution within the wood, and the effects of leaching on fire performance. A clear improvement in the fire resistance of the zinc borate -treated wood could be verified for all exposure times; leaching did not affect its fire retardant properties despite the harsh conditions of the test, making the product potentially suitable for outdoor use.
Science fiction media representations of exoplanets: portrayals of changing astronomical discoveries
Authors: Puranen Emma Johanna , Finer Emily , Helling Christiane , Smith V. Anne
Published: March 2024

Interest in science fiction's (SF's) potential science communication use is hindered by concerns about SF misrepresenting science. This study addresses these concerns by asking how SF media reflects scientific findings in exoplanet science.

Systemic lupus erythematosus (SLE) is a chronic, systemic autoimmune with autoantibody production, complementactivation, and immune complex deposition. SLE patients have higher mortality rates as compared to the general populationEven though there have been improvements in finding and treating diseases, cancer is still a major reason for death in this group.The most common type of cancer is Basal cell carcinoma, and it is widespread. The risk of malignancy in SLE is of considerableinterest because the immune and genetic pathways underlying the pathogenesis of SLE and the immunosuppressant drugs (ISDs)used in its management may mediate this altered risk. Here, we present a case of long-standing SLE in an elderly female who wason treatment for the same. She presented with a chronic ulcer over her scalp. She got checked, and a biopsy showed she hadBasal Cell Carcinoma on her scalp. Doctors removed it with surgery and covered the open area with skin from another part ofher body. At her first checkup, everything looked good, and the new skin was healing well. Even though skin cancers are knownto happen in people with certain skin conditions, getting Basal Cell Carcinoma with lupus is very uncommon. In various cohortstudies of adults with SLE and overall risk of malignancy, ranging from 1992 to 2017, it was found that though cutaneousmalignancies did occur, not a single study reported Basal Cell Carcinoma.

The organization competes to increase its productivity by implementing a form of governance that is agile to technological changes. However, in its implementation, challenges inevitably arise, such as resistance to change, especially in terms of organizational structure. This study aims to examine the effect of agile governance, as proposed by Luna et al. (2015), consisting of six sub-variables (environmental factors, moderator factors, agile capabilities, governance capabilities, business operations, value delivery), on structural resistance (Kumar & Kant, 2006). This study uses a quantitative approach. Data were obtained by distributing questionnaires to 400 civil servants in Indonesia. Data were analyzed using partial least squares structural equation modeling (SEM-PLS) with the help of R software. The results showed that environmental factors, moderator factors, and agile capabilities have a negative and significant effect on structural resistance. On the other hand, business operations and value delivery have a positive and significant effect on structural resistance. Meanwhile, governance capabilities do not have a significant effect on the structural resistance of public-sector organizations. These findings contribute to the understanding of the challenges associated with implementing agile governance and highlight the importance of addressing resistance to change, particularly in terms of organizational structure.
