Vampires in the village Žrnovo on the island of Korčula: following an archival document from the 18th century

Središnja tema rada usmjerena je na raščlambu spisa pohranjenog u Državnom arhivu u Mlecima (fond: Capi del Consiglio de’ Dieci: Lettere di Rettori e di altre cariche) koji se odnosi na događaj iz 1748. godine u korčulanskom selu Žrnovo, kada su mještani – vjerujući da su se pojavili vampiri – oskvrnuli nekoliko mjesnih grobova. U radu se podrobno iznose osnovni podaci iz spisa te rečeni događaj analizira u širem društvenom kontekstu i prate se lokalna vjerovanja.The main interest of this essay is the analysis of the document from the State Archive in Venice (file: Capi del Consiglio de’ Dieci: Lettere di Rettori e di altre cariche) which is connected with the episode from 1748 when the inhabitants of the village Žrnove on the island of Korčula in Croatia opened tombs on the local cemetery in the fear of the vampires treating. This essay try to show some social circumstances connected with this event as well as a local vernacular tradition concerning superstitions

Spatial working memory in neurofibromatosis 1: Altered neural activity and functional connectivity.

BackgroundNeurofibromatosis Type 1 (NF1) is a genetic disorder that disrupts central nervous system development and neuronal function. Cognitively, NF1 is characterized by difficulties with executive control and visuospatial abilities. Little is known about the neural substrates underlying these deficits. The current study utilized Blood-Oxygen-Level-Dependent (BOLD) functional MRI (fMRI) to explore the neural correlates of spatial working memory (WM) deficits in patients with NF1.MethodsBOLD images were acquired from 23 adults with NF1 (age M = 32.69; 61% male) and 25 matched healthy controls (age M = 33.08; 64% male) during an in-scanner visuo-spatial WM task. Whole brain functional and psycho-physiological interaction analyses were utilized to investigate neural activity and functional connectivity, respectively, during visuo-spatial WM performance. Participants also completed behavioral measures of spatial reasoning and verbal WM.ResultsRelative to healthy controls, participants with NF1 showed reduced recruitment of key components of WM circuitry, the left dorsolateral prefrontal cortex and right parietal cortex. In addition, healthy controls exhibited greater simultaneous deactivation between the posterior cingulate cortex (PCC) and temporal regions than NF1 patients. In contrast, NF1 patients showed greater PCC and bilateral parietal connectivity with visual cortices as well as between the PCC and the cerebellum. In NF1 participants, increased functional coupling of the PCC with frontal and parietal regions was associated with better spatial reasoning and WM performance, respectively; these relationships were not observed in controls.ConclusionsDysfunctional engagement of WM circuitry, and aberrant functional connectivity of 'task-negative' regions in NF1 patients may underlie spatial WM difficulties characteristic of the disorder

Evaluation of an evidence-based guidance on the reduction of physical restraints in nursing homes: a cluster-randomised controlled trial [ISRCTN34974819]

<p>Abstract</p> <p>Background</p> <p>Physical restraints are regularly applied in German nursing homes. Their frequency varies substantially between centres. Beneficial effects of physical restraints have not been proven, however, observational studies and case reports suggest various adverse effects. We developed an evidence-based guidance on this topic. The present study evaluates the clinical efficacy and safety of an intervention programme based on this guidance aimed to reduce physical restraints and minimise centre variations.</p> <p>Methods/Design</p> <p>Cluster-randomised controlled trial with nursing homes randomised either to the intervention group or to the control group with standard information. The intervention comprises a structured information programme for nursing staff, information materials for legal guardians and residents' relatives and a one-day training workshop for nominated nurses. A total of 36 nursing home clusters including approximately 3000 residents will be recruited. Each cluster has to fulfil the inclusion criteria of at least 20% prevalence of physical restraints at baseline. The primary endpoint is the number of residents with at least one physical restraint at six months. Secondary outcome measures are the number of falls and fall-related fractures.</p> <p>Discussion</p> <p>If successful, the intervention should be implemented throughout Germany. In case the intervention does not succeed, a three-month pre-post-study with an optimised intervention programme within the control group will follow the randomised trial.</p> <p>Trial registration</p> <p>ISRCTN34974819</p
