First record of partial albinism in the critically endangered Angelshark (Squatina squatina) (Linnaeus, 1758).

We report the first case of partial albinism in the Critically Endangered angelshark, Squatina squatina. The encounter with this specimen took place while SCUBA diving on the beach of Tufia, located on the east coast of the island of Gran Canaria on 2 April 2021. This is also the first confirmed finding of an albino elasmobranch specimen in the Canary Island archipelago.

Advancing EBP culture and competencies through an academic-research partnership: Process and outcomes of an EBP scholar program.

BACKGROUND: Evidence-based practice (EBP) is increasingly being adopted in healthcare organizations to improve patient care and outcomes. Yet, barriers remain that prevent consistent implementation of EBP in clinical settings. AIMS: To increase EBP competencies and promote practice change, a regional academic-community hospital in Los Angeles, California, jointly with a university school of nursing, developed and implemented an EBP scholar program. METHODS: A multistep EBP process was delivered during monthly didactic workshops to ensure optimal delivery and acquisition of EBP core competencies. The Iowa Model of Evidence-Based Practice to Promote Quality Care was integrated into the curriculum to assist program scholar's efforts to systematically direct EBP implementation at the organizational level. Additional strategies were incorporated including one-to-one mentoring, institutional recognition, and protected time. The 13-item EBP Competency Scale for practicing registered professional nurses was used to measure EBP competency at baseline and post-program completion. RESULTS: Five recruited scholars completed the baseline survey and three completed the postsurvey. EBP competency increased from 52.9% to 62.75%. Scholars submitted abstracts for conference poster presentation, podium presentations, and conference poster awards. One article was submitted and accepted for journal publication. LINKING EVIDENCE TO ACTION: A multistep EBP process can enhance EBP delivery, improve EBP competency, and facilitate dissemination.

Angel sharks (Squatinidae): A review of biological knowledge and exploitation.

Angel sharks (Squatina spp.) are distributed in warm temperate to tropical waters around the world. Many species occur in shelf seas and exhibit seasonal inshore-offshore migrations, moving inshore to give birth. Consequently, there can be high spatial overlap of angel shark populations with fisheries and other human activities. Their dorso-ventrally flattened body shape, large size (most species attain >100 cm total length, LT ) and demersal nature means that they may be taken in a variety of demersal fishing gears from birth. Available data indicate that angel sharks typically have a biennial reproductive cycle, with litter sizes generally <20 and the young born at c. 20-30 cm. The biological characteristics of angel sharks render them susceptible to overexploitation, as exemplified by the decline of Squatina squatina from many parts of its former range in the north-east Atlantic and Mediterranean Sea. Currently, half of the 22 recognized extant species of angel shark are classed as Threatened on the International Union for Conservation of Nature (IUCN) Red List (with a further three classified as Data Deficient). Given the biological vulnerability of angel sharks, and that many species are data-limited, the current paper provides a review of available biological information and fisheries data pertaining to this family.

Exploring the association between diabetes and breast cancer morbidity: considerations for quality care improvements among Latinas.

OBJECTIVE: Cancer and diabetes are two severe chronic illnesses that often co-occur. In cancer patients, diabetes increases the risk for treatment complexities and mortality. Yet patient-reported outcomes with co-occurring chronic illness are understudied. DESIGN: This preliminary study investigated the association of diabetes with breast cancer-related morbidity among underserved Latina breast cancer survivors (BCS). PARTICIPANTS: 137 Latina BCS were recruited from the California Cancer Registry and hospitals.Setting and Main Outcome Measure(s): BCS completed a self-administered mailed questionnaire assessing demographic and medical characteristics e.g. Type2 diabetes mellitus (T2DM). RESULTS: 28% Latina BCS reported co-occurring T2DM at twice the general population rate. Diabetes was most prevalent among Latina BCS > 65 years (43%). Latina BCS with diabetes were more likely to report advanced cancer staging at diagnosis (P = 0.036) and more lymphedema symptoms (P = 0.036). Results suggest non-significant but lower general health and greater physical functioning limitations among BCS with T2DM. CONCLUSIONS: This study has relevance for precision population medicine by (i) consideration of routine diabetes screening in Latina BCS, (ii) underscoring attention to disease co-occurrence in treatment planning and care delivery and (iii) informing follow-up care and survivorship care planning e.g. patient self-management, oncology and primarily care surveillance and specialty care. Our findings can inform providers, survivors and caregivers about the impact of disease co-occurrence that influence clinically and patient responsive care for both initial treatment and long-term follow-up care to address disparities.

Aggregative Behaviour of Spiny Butterfly Rays (Gymnura altavela, Linnaeus, 1758) in the Shallow Coastal Zones of Gran Canaria in the Eastern Central Atlantic.

The presence of spiny butterfly rays, Gymnura altavela, in waters less than 20 m deep off the Canary Islands shows marked seasonality, with relatively high abundances in the summer and autumn. Large aggregations of sometimes hundreds of individuals, primarily females, appear in specific shallow areas of the archipelago and seem to be associated with the seasonal variation in water temperature. This seasonal pattern of presence or absence in shallow areas suggests that spiny butterfly rays migrate into deeper waters or other unknown areas during the rest of the year. G. altavela shows sexual dimorphism; in our study, females were larger and more abundant than males, with a sex ratio of 1:18.9. The species' estimated asymptotic length, L∞, was 183.75 cm and thus close to the common length reported for the species (200 cm). The von Bertalanffy growth constant (k) oscillated between 0.210 and 0.310 year-1, as similarly described for the species in the Western North Atlantic off the U.S. coast. From June to November, the seawater temperature oscillated between 19 and 24 °C, and massive aggregations of females occurred at 22-24 °C and in a few specific sandy beaches on the islands. Spiny butterfly rays, mostly females, show a preference for aggregating in shallow waters during summertime, probably conditionate to mating or breeding behaviour.

Differences in the occurrence and abundance of batoids across an oceanic archipelago using complementary data sources: Implications for conservation.

Batoids, distributed from shallow to abyssal depths, are considerably vulnerable to anthropogenic threats. Data deficiencies on the distribution patterns of batoids, however, challenge their effective management and conservation. In this study, we took advantage of the particular geological and geomorphological configuration of the Canary Islands, across an east-to-west gradient in the eastern Atlantic Ocean, to assess whether patterns in the occurrence and abundance of batoids varied between groups of islands (western, central, and eastern). Data were collected from shallow (<40 m, via underwater visual counts and by a local community science program) and deep waters (60-700 m, via ROV deployments). Eleven species of batoids, assessed by the IUCN Red List of Threatened Species, were registered, including three "Critically Endangered" (Aetomylaeus bovinus, Dipturus batis, and Myliobatis aquila), three "Endangered" (Gymnura altavela, Mobula mobular, and Rostroraja alba), two "Vulnerable" (Dasyatis pastinaca and Raja maderenseis), and two "Data Deficient" (Taeniurops grabata and Torpedo marmorata). Also, a "Least Concern" species (Bathytoshia lata) was observed. Overall, batoids were ~1 to 2 orders of magnitude more abundant in the central and eastern islands, relative to the western islands. This pattern was consistent among the three sources of data and for both shallow and deep waters. This study, therefore, shows differences in the abundance of batoids across an oceanic archipelago, likely related to varying insular shelf area, availability of habitats, and proximity to the nearby continental (African) mass. Large variation in population abundances among islands suggests that "whole" archipelago management strategies are unlikely to provide adequate conservation. Instead, management plans should be adjusted individually per island and complemented with focused research to fill data gaps on the spatial use and movements of these iconic species.

Survivorship: a qualitative investigation of Latinas diagnosed with cervical cancer.

Latinas experience high rates of cervical cancer (CCA) in the U.S. This health-related quality of life (HRQOL) qualitative study was conducted with key informant and focus groups (N = 26). The results indicate that overall Latinas experience persistent concerns: Physical challenges including pain, and bladder, bowel, and sexual health problems; medical care barriers (e.g., difficulties accessing quality care, poor patient-physician relationship); functional issues including employment difficulties; and personal concerns including family and relationship burdens. Spiritual, familial, and cultural factors promote coping and well-being but may delay care seeking. In summary, Latinas diagnosed with CCA face a burdensome survivorship experience. Increases in medical and psychosocial services are greatly needed for Latinas to improve cancer outcomes including HRQOL.
