The Coloniality of Language: Race, Expressivity, Power, and the Darker Side of Modernity
This article presents a new framework to analyze linguistic relations of power that examines the linguistic effects of what Aníbal Quijano has theorized as “the coloniality of power.” The argument is organized in two sections. The first section introduces “the coloniality of language,” an expression the author uses to refer to the process of racialization of colonized populations as communicative agents beginning in the sixteenth century and continuing until today. This section includes an account of the language and communication paradigm being developed at the time of the Conquest, which, the author argues, contains the coloniality inside. In the second section, the author proposes to shift paradigms to get outside the “conceptual and social prison” of modernity/coloniality and understand colonized-colonialized languages and colonized- colonialized speakers differently. The conclusion illustrates some ideas and concerns about accessing and fostering decolonial alternatives that come forth from the article’s critical analysis

Baseline conditions and nutritional state upon hospitalization are the greatest risks for mortality for cardiovascular diseases and for several classes of diseases : a retrospective study
The aim of this retrospective study was to evaluate risk factors for 3-years mortality after hospital discharge in all inpatients admitted to a general hospital in Milano, Italy. A total of 2580 consecutive patients admitted to Ospedale San Paolo, July 1 to December 31, 2012, for several classes of diseases (internal medicine, cancer, infectious diseases, trauma and surgery, pneumonia, and heart diseases) were studied. Age, total disease, type of admission, length of admission, age-adjusted Charlson index, prognostic nutritional index (PNI), and full blood count were evaluated. Univariate Cox models were used to evaluate the association between variables and death. Of the 2580 consecutive patients (age 66.8 +/- 19.36 years, mean +/- SD), 920 died within 3 years after discharge. At univariate analysis, all investigated variables, except sex and lymphocytes, were associated with patient death. Stepwise regression analyses revealed that the age-adjusted Charlson index or age plus total diseases, type of admission, number of admissions, and PNI were significant risk factors in the whole sample and in some classes of disease. Results were superimposable when considering death from date of admission instead of date of discharge, meaning that in-hospital death was not relevant to the total death count (115 out of 902). Seriousness of baseline conditions represents the major risk factor for mortality in most classes of disease, and possibly influences other predictors, such as type of admission and length of stay. This suggests that the current model of hospital admission might be improved, for instance, through comprehensive care at home, instead of hospital admission, or before admission

Explicit motor sequence learning after stroke: a neuropsychological study
Motor learning interacts with and shapes experience-dependent cerebral plasticity. In stroke patients with paresis of the upper limb, motor recovery was proposed to reflect a process of re-learning the lost/impaired skill, which interacts with rehabilitation. However, to what extent stroke patients with hemiparesis may retain the ability of learning with their affected limb remains an unsolved issue, that was addressed by this study. Nineteen patients, with a cerebrovascular lesion affecting the right or the left hemisphere, underwent an explicit motor learning task (finger tapping task, FTT), which was performed with the paretic hand. Eighteen age-matched healthy participants served as controls. Motor performance was assessed during the learning phase (i.e., online learning), as well as immediately at the end of practice, and after 90 min and 24 h (i.e., retention). Results show that overall, as compared to the control group, stroke patients, regardless of the side (left/right) of the hemispheric lesion, do not show a reliable practice-dependent improvement; consequently, no retention could be detected in the long-term (after 90 min and 24 h). The motor learning impairment was associated with subcortical damage, predominantly affecting the basal ganglia; conversely, it was not associated with age, time elapsed from stroke, severity of upper-limb motor and sensory deficits, and the general neurological condition. This evidence expands our understanding regarding the potential of post-stroke motor recovery through motor practice, suggesting a potential key role of basal ganglia, not only in implicit motor learning as previously pointed out, but also in explicit finger tapping motor tasks
The focal attention window size explains letter substitution errors in reading
Acquired Neglect Dyslexia is often associated with right-hemisphere brain damage and is mainly characterized by omissions and substitutions in reading single words. Martelli et al. proposed in 2011 that these two types of error are due to different mechanisms. Omissions should depend on neglect plus an oculomotor deficit, whilst substitutions on the difficulty with which the letters are perceptually segregated from each other (i.e., crowding phenomenon). In this study, we hypothesized that a deficit of focal attention could determine a pathological crowding effect, leading to imprecise letter identification and consequently substitution errors. In Experiment 1, three brain-damaged patients, suffering from peripheral dyslexia, mainly characterized by substitutions, underwent an assessment of error distribution in reading pseudowords and a T detection task as a function of cue size and timing, in order to measure focal attention. Each patient, when compared to a control group, showed a deficit in adjusting the attentional focus. In Experiment 2, a group of 17 right-brain-damaged patients were asked to perform the focal attention task and to read single words and pseudowords as a function of inter-letter spacing. The results allowed us to confirm a more general association between substitution-type reading errors and the performance in the focal attention task

Cholesterol metabolism after bariatric surgery in grade 3 obesity : differences between malabsorptive and restrictive procedures
OBJECTIVEdMalabsorptive bariatric surgery (biliopancreatic diversion and biliointestinal
bypass [BIBP]) reduces serum cholesterol levels more than restrictive surgery (adjustable gastric
banding [AGB]), and this is thought to be due to greater weight loss. Our aim was to evaluate the
changes of cholesterol metabolism induced by malabsorptive and restrictive surgery independent
of weight loss.
RESEARCH DESIGNANDMETHODSdIn a nonrandomized, self-selected, unblinded,
active-comparator, bicenter, 6-month study, glucose metabolism (blood glucose and serum insulin
levels and homeostasis model assessment of insulin resistance [HOMA-IR] index) and
cholesterol metabolism (absorption: serum campesterol and sitosterol levels; synthesis: serum
lathosterol levels; catabolism: rate of appearance and serum concentrations of serum 7-a- and
serum 27-OH-cholesterol after infusions of deuterated 7-a- and 27-OH-cholesterol in sequence)
were assessed in grade 3 obesity subjects undergoing BIBP (n = 10) and AGB (n = 10). Evaluations
were performed before and 6 months after surgery.
RESULTSdSubjects had similar values at baseline.Weight loss was similar in the two groups
of subjects, and blood glucose, insulin levels, HOMA-IR, and triglycerides decreased in a similar
way. In contrast, serumcholesterol, LDL cholesterol, non-HDL cholesterol, serum sitosterol, and
campesterol levels decreased and lathosterol levels increased only in BIBP subjects, not in AGB
subjects. A significant increase in 7-a-OH-cholesterol occurred only with BIBP; serum 27-OHcholesterol
decreased in both groups.
CONCLUSIONSdMalabsorptive surgery specifically affects cholesterol levels, independent
of weight loss and independent of glucose metabolism and insulin resistance. Decreased sterol
absorption leads to decreased cholesterol and LDL cholesterol levels, accompanied by enhanced
cholesterol synthesis and enhanced cholesterol catabolism. Compared with AGB, BIBP provides
greater cholesterol lowering
