The Association between Daytime Napping and Cognitive Functioning in Chronic Fatigue Syndrome
No full textOBJECTIVES
The precise relationship between sleep and physical and mental functioning in chronic fatigue syndrome (CFS) has not been examined directly, nor has the impact of daytime napping. This study aimed to examine self-reported sleep in patients with CFS and explore whether sleep quality and daytime napping, specific patient characteristics (gender, illness length) and levels of anxiety and depression, predicted daytime fatigue severity, levels of daytime sleepiness and cognitive functioning, all key dimensions of the illness experience.
METHODS
118 adults meeting the 1994 CDC case criteria for CFS completed a standardised sleep diary over 14 days. Momentary functional assessments of fatigue, sleepiness, cognition and mood were completed by patients as part of usual care. Levels of daytime functioning and disability were quantified using symptom assessment tools, measuring fatigue (Chalder Fatigue Scale), sleepiness (Epworth Sleepiness Scale), cognitive functioning (Trail Making Test, Cognitive Failures Questionnaire), and mood (Hospital Anxiety and Depression Scale).
RESULTS
Hierarchical Regressions demonstrated that a shorter time since diagnosis, higher depression and longer wake time after sleep onset predicted 23.4% of the variance in fatigue severity (p <.001). Being male, higher depression and more afternoon naps predicted 25.6% of the variance in objective cognitive dysfunction (p <.001). Higher anxiety and depression and morning napping predicted 32.2% of the variance in subjective cognitive dysfunction (p <.001). When patients were classified into groups of mild and moderate sleepiness, those with longer daytime naps, those who mainly napped in the afternoon, and those with higher levels of anxiety, were more likely to be in the moderately sleepy group.
CONCLUSIONS
Napping, particularly in the afternoon is associated with poorer cognitive functioning and more daytime sleepiness in CFS. These findings have clinical implications for symptom management strategies
O nítido e o obscuro da visao: propondo olhares
No full textA partir de considerações sobre a ideia de imagem, e em especial sobre a fotografia, da autora Susan Sontag, a pretensão desse texto será de transcrever as sensações despertadas pelo olhar que percorre trilhas sobre um conjunto específico de fotografias de um determinado autor. A gravitação será sobre os trabalhos do fotógrafo brasileiro Claudio Edinger, cujos cenários foram cidades como de São Paulo, Rio de Janeiro e Paris.Starting with some considerations about the concept of image, especially photographs, by Susan Sontag, the aim of this text is to transcribe the feelings that were raised by the pathways created by looking at a specific set of photographs by one specific author. The focus will be on the works of the Brazilian photographer Claudio Edinger, whose sceneries were the cities of São Paulo, Rio de Janeiro and Paris
Which Opinion Should a Clinical Ethicist Give: Personal Viewpoint or Professional Consensus?
No full textWhen clinical ethicists are called upon to give a recommendation
regarding patient care, they may be faced with a dilemma of their own. If
their own personal opinion is not widely shared, the ethicist will have three
options. These include: (1) giving their own opinion; (2) giving the widely
shared opinion; and (3) giving both opinions, leaving the physician to select
which opinion to accept. The intentions of this article are to evaluate
strengths and weaknesses of these three alternatives and to suggest that
ethics consultants recognize and deal with this issue. Two cases are presented
to explore the limitations of each option. The author suggests that when the
views of ethics consultants differ from the consensus view, the consultant
should give the consensus view, their own dissenting view and the arguments in
support of each position
CBT-I and the short sleep duration insomnia phenotype: a comment on Bathgate, Edinger and Krystal
No full textAlthough the DSM-5 and the ICSD-3 do not discriminate among insomnia types or subtypes anymore, it appears that some specific insomnia phenotypes remain important to study. One of them is the object of the present paper: insomnia with short sleep duration. Since Vgontzas and colleagues (1) put forward a heuristic model of two insomnia phenotypes based on objective sleep duration, they have suggested that insomnia with short sleep duration is the most severe biological phenotype of insomnia, and research in this area has been blooming. The Penn State group has studied the impact of this phenotype on adolescents and its association with depression risks and inflammation (2-4). A recent review by Fernandez-Mandoza (5) also suggested that besides increased physiological hyperarousal and cardiometabolic and neuropsychiatric risks, insomnia with short sleep duration may even respond differently to treatment compared to other insomnia phenotypes
Iophon piceum Arctic 1882

Brunel <i>et al.</i> 1998: 62–63, Dinn & Leys 2018: 32.</p> <p> <b>Material examined.</b> CMNI 2018-0177, specimen in 95% ethanol, collected by Curtis Dinn by BX 650 MK III box core; July 14, 2017, 507m depth (62° 49.126’ N, 66°56.354’ W) operated from the <i>CCGS Amundsen</i>, Frobisher Bay, Canada.</p> <p> <b>Description</b>. Large fragments of a cup shaped specimen were collected (Fig. 4A). The whole specimen is thought to have been 10–20 cm in diameter, but the growth form was not obvious as the sponge was collected in pieces. The spongin fibres and spicules form a lattice. The sponge is rough to the touch, fragile and dark black in colour. The black pigment leeches out of preserved specimens and will transfer the colour to ethanol. The spicules (Fig. 4 B–F) consist of acanthostyles 320 (275–349) x 16 (12–19) µm; tylotes with spined heads 260 (237–278) x 12 (9–16) µm; spurred anisochelae 18.5 (13–32) µm; and bipocilli with unequal alae, both with fine teeth 11.8 (8.7–16.5) µm.</p> <p> <b>Taxonomic Remarks</b>. The spicule measurements agree with those in the original description by Vosmaer (1882) and in subsequent descriptions by Lundbeck (1905) and Arndt (1935) (Table 4). Two slight variations in spicule size were noted in this specimen: tylote thickness reaches a maximum of 16 µm whereas the thickest tylotes described by Lundbeck (1905) are 11 µm. The acanthostyles in this specimen do not exceed 350 µm, whereas Lundbeck states that acanthostyles can reach 450 µm. Vosmaer (1882) described this species as being of a “pitchy colour” and having a cup-shape. Lundbeck (1905) describes the sponge as leaf shaped and erect with an attachment to the seafloor at the base. The overall spicule complement in the present specimen is very similar to Lundbeck’s (1905) description. The bipocilli in the present specimen are rounded, with numerous fine teeth, similar to those described in Lundbeck (1905). However, Lundbeck (1905) also describes some bipocilli that attain “monstrous forms” where the alae split from the shaft, but these types of spicules were not seen in the present specimen. Despite minor variations in spicule size, the present specimen agrees with previous descriptions, especially in growth form and colour.</p> <p> 1 from Van Soest <i>et al</i>. (2000)</p> <p> <b>Discussion</b>. <i>Iophon</i> c.f. <i>piceum</i> was previously identified by Murillo <i>et al.</i> (2018) from eighteen specimens collected in the eastern Canadian Arctic. The assignment of these specimens to species is not assured as spicule measurements and photos were not presented, and the author suggests that more than one species may be represented (J. Murillo personal communication, Nov. 2018). The cup-shaped growth form, thick acanthostyles, bipocilli with fine teeth, and pitch-black colouration are clear identifiers of this species, thus the difficulty of the authors to identify their specimens to the species level suggest congeneric species are present in their samples. Previous records show collections near SW Iceland and in the Barents Sea and White Sea (Lundbeck 1905). The species was also collected from a depth of 719 m on the western Greenland shelf by Lundbeck (1905) during the Danish Ingolf-Expedition. Vosmaer found this species at 350 m in the Barents Sea. Brunel <i>et al.</i> (1998) note that de Laubenfels thought that Lambe’s (1900) records of <i>I. cheliferum</i> were actually <i>I. nigricans,</i> and Lévi suggested that the specimens were actually <i>I. piceum</i>. Since there is much confusion about the identity of <i>Iophon</i> specimens in the region, a revision of the genus is recommended. This sponge was not seen in ROV video from the site near Hill Island, which supports reports that it is primarily a deep-water, rocky bottom species. The species was only found in the deep water near the mouth of Frobisher Bay and not in the sandy and shallow inner regions of the bay.</p>Published as part of <i>Dinn, Curtis, Edinger, Evan & Leys, Sally P., 2019, Sponge (Porifera) fauna of Frobisher Bay, Baffin Island, Canada with the description of an Iophon rich sponge garden, pp. 301-325 in Zootaxa 4576 (2)</i> on pages 311-313, DOI: 10.11646/zootaxa.4576.2.5, <a href="http://zenodo.org/record/2624952">http://zenodo.org/record/2624952</a>
When do companies have a positive duty to engage in philanthropy? An empirical application of Mieth’s five criteria for positive duties of individuals in the corporate context
No full textAlthough the negative duties of corporations have been intensively discussed and researched, the more elusive phenomenon of positive duties such as making an active effort to help people in need represents a major research void. On the level of individual actors, clear criteria exist to define cases of ethical failures to assist a person, or in other words, of disregarding one’s positive duties. The study at hand uses a framework of criteria developed to define positive duties of individuals from contemporary deontological philosophy developed by Mieth (2012). First, the framework is transferred to the corporate level to derive normative criteria for the positive duties of corporations. Second, the author uses a quantitative-empirical approach to test the framework
High resolution habitat mapping to describe coastal denning habitat of a Canadian species at risk, Atlantic wolffish (Anarhichas lupus)
No full textThe Atlantic Wolffish (Anarhichas lupus) is listed by Canadaâ s Species at Risk Act as a species of special concern. Effective conservation strategies rely on accurate knowledge of habitat requirements, distribution, and vulnerabilities; however, current management plans cite lack of wolffish habitat data as a key limitation. For this study, coastal Atlantic Wolffish denning habitat was characterized and mapped with high resolution multibeam data and seafloor video in Conception Bay, Newfoundland. Four Atlantic Wolffish dens, used for feeding, spawning and egg-guarding, were surveyed and mapped. Based on the geomorphology and substrate of these dens, a supervised classification was applied to the multibeam bathymetry and backscatter data to identify other potential denning areas. Predicted denning habitat, limited by the occurrence of suitable rocky substrate, is most prevalent in shallow waters (The accepted manuscript in pdf format is listed with the files at the bottom of this page.
