Stop the hovering : The helicopter mentor, a new view on the dysfunctional mentor

The concept of a helicopter mentor was introduced in the current study. A scale was developed to measure helicopter mentoring. To provide validity evidence for the helicopter mentoring measure, assessments of typical mentoring, dysfunctional mentoring, anxiety and self-esteem were used. A confirmatory factor analysis was conducted on the 20-item four factor helicopter mentoring measure, looking at the following four subscales: Results suggested dropping problematic items, resulting in a 14-item four factor model, where six of the original 20 items were removed. All subscales had acceptable levels of internal reliability. As hypothesized, the helicopter mentoring measure was negatively correlated with the typical mentoring measure, and distinct from but related to dysfunctional mentoring. Helicopter mentoring was also not significantly correlated to anxiety, but was significantly correlated to self-esteem. These results suggest that helicopter mentoring is an important construct to examine in the workplace, and future research should continue to investigate helicopter mentoring.  M.A

De novo descending aorta thrombus in a patient with metastatic colorectal cancer: A case report

Thromboembolic events in patients with cancer are frequently reported in literature and usually involve the venous circulation. De novo thrombus formation in the arterial system without any underlying atherosclerosis, dissection or aneurysm is extremely rare. We report the case of a patient with metastatic colorectal carcinoma who developed a thrombus in the descending aorta without any intervention or risk factors. The patient presented with non-specific gastrointestinal symptoms. A CT scan revealed an aortic thrombus obstructing 70% of the lumen. She opted for no treatment of her thrombus and was later complicated by extensive lower limb emboli. Patients with aortic thrombosis usually present with subtle symptoms which may be underestimated by both the patient and the physician. A high index of suspicion is required for early recognition and prevention of complications

Primary Hepatic Carcinoid Tumor with Poor Outcome

Primary Hepatic Carcinoid Tumor (PHCT) represents an extremely rare clinical entity with only a few cases reported to date. These tumors are rarely associated with metastasis and surgical resection is usually curative. Herein, we report two cases of PHCT associated with poor outcomes due to late diagnosis. Both cases presented late with non-specific symptoms. One patient presented after a 2-week history of symptoms and the second case had a longstanding two years symptomatic interval during which he remained undiagnosed and not properly worked up. Both these cases were diagnosed with hepatic carcinoid tumor, which originates from neuroendocrine cells. Case 1 opted for palliative care and expired in one month’s time. Surgical resection was advised to the second case, but he left against medical advice

El Acuarismo y sus riesgos

Por milenios los seres humanos hemos servido de agentes dispersantes de organismos, transportando voluntariamente nuestras especies domésticas (por ejemplo, aves de corral, ganado, etc.) que, a su vez, han dispersado inadvertidamente a sus parásitos. Ante el hallazgo de una nueva especie de parásito exótico en peces de acuarios locales, resulta necesario analizar el riesgo potencial de su dispersión a los ambientes acuáticos naturales

The southern river otter lontra provocax in the province of chubut: historical distribution and current situation

La distribución actual del huillín Lontra provocax en la Patagonia continental argentina representa ca. 20 % de su distribución histórica, con una única población estable conocida que se encuentra en el suroeste de la cuenca del Río Limay (límite de Neuquén y Río Negro). Aquí reconstruimos la distribución histórica de la especie en la provincia del Chubut en base a bibliografía; además, recopilamos información sobre la presencia potencial y con rmada de la especie e informamos un registro actual para la provincia. Finalmente analizamos estos avistajes con relación a la situación histórica y la importancia para la restauración de las poblaciones de huillín de la provincia del Chubut.. The present range of the southern river otter Lontra provocax in Argentinean continental Patagonia represents only c. 20 % of its original distribution, with only one known population that is found in the southwestern area of the Río Limay basin (border between Neuquén and Río Negro provinces). Based on bibliography, we reconstruct the historic distribution of the species in Chubut, we compile information on its potential and con rmed presence and report a new sighting for the province. Finally, we analyze these sightings in relation to the original situation and its relevance for the restoration of the southern river otter populations of Chubut province.Fil: Fasola, Laura.

Análisis de esfuerzo de muestreo de himenópteros parasitoides en tres ambientes del Este uruguayo = Sampling effort analysis for hymenopteran parasitoids in three environments of Eastern Uruguay

Los himenópteros parasitoides brindan el servicio ecosistémico de control biológico de numerosas plagas agrícolas. Muchos de ellos son minúsculos y su separación e identificación son altamente trabajosas. Entre diciembre de 2014 y diciembre de 2015 se condujeron colectas quincenales con dos trampas Malaise en un área natural, una de pastoreo con ganado vacuno y una con ganadería vacuna con agricultura inverno-estival, en las cercanías de la ciudad de Castillos, Rocha, Uruguay. La separación de taxones colectados se realizó en el Centro Universitario Regional del Este (CURE) – Rocha y se identificaron las familias de los himenópteros parasitoides en Ribeirão Preto, Brasil. Se colectaron 36.718 parasitoides de 31 familias de Hymenoptera parasitoides. Con datos transformados a abundancia proporcional en la muestra se construyeron sets considerando una (N = 72) o dos quincenas (N = 144) y se realizó un análisis multivariado de acumulación de familias (perMANOVA). Considerando la mitad (una quincena) o la totalidad (dos quincenas) de las fechas, indistintamente, es posible ajustar el esfuerzo de muestreo para disminuir la frecuencia y/o los meses de muestreo, sin pérdida significativa en el hallazgo de nuevas familias. Este estudio contribuye a mantener la eficiencia y validez del trabajo y a reducir costos en recursos humanos y materiales

Global distribution of a key trophic guild contrasts with common latitudinal diversity patterns

Most hypotheses explaining the general gradient of higher diversity toward the equator are implicit or explicit about greater species packing in the tropics. However, global patterns of diversity within guilds, including trophic guilds (i.e., groups of organisms that use similar food resources), are poorly known. We explored global diversity patterns of a key trophic guild in stream ecosystems, the detritivore shredders. This was motivated by the fundamental ecological role of shredders as decomposers of leaf litter and by some records pointing to low shredder diversity and abundance in the tropics, which contrasts with diversity patterns of most major taxa for which broad-scale latitudinal patterns haven been examined. Given this evidence, we hypothesized that shredders are more abundant and diverse in temperate than in tropical streams, and that this pattern is related to the higher temperatures and lower availability of high-quality leaf litter in the tropics. Our comprehensive global survey (129 stream sites from 14 regions on six continents) corroborated the expectedlatitudinal pattern and showed that shredder distribution (abundance, diversity and assemblage composition) was explained by a combination of factors, including water temperature (some taxa were restricted to cool waters) and biogeography (some taxa were more diverse in particular biogeographic realms). In contrast to our hypothesis, shredder diversity was unrelated to leaf toughness, but it was inversely related to litter diversity. Our findings markedly contrast with global trends of diversity for most taxa, and with the general rule of higher consumer diversity at higher levels of resource diversity. Moreover, they highlight the emerging role of temperature in understanding global patterns of diversity, which is of great relevance in the face of projected global warming. © 2011 by the Ecological Society of America.Peer Reviewe
