Sensitivity of the Montreal Cognitive Assessment in screening for cognitive impairment in patients with newly diagnosed high-grade glioma

Journal of Neuro-Oncology - Cognitive impairment is frequent in patients with high-grade glioma and requires cognitive follow-up. Cognitive screening tools such as the Montreal Cognitive Assessment...     

Acute psycho-physiological responses to perceptually regulated hypoxic and normoxic interval walks in overweight-to-obese adults

ObjectivesWe investigated psycho-physiological responses to perceptually regulated interval walks in hypoxia versus normoxia in obese individuals.DesignWithin-participants repeated measures.MethodsTen obese adults (BMI = 32 ± 3 kg/m^?2) completed a 60-min interval session (15 × 2 min walking at a rating of perceived exertion of 14 on the 6–20 Borg scale with 2 min of rest) either in hypoxia (FiO₂ = 13.0%, HYP) or normoxia (NOR). A third trial replicating the HYP speed pattern was carried out in normoxia as a control (CON). Exercise responses were analysed comparing the average of 1st to 3rd exercise bouts to those of the 4th–6th, 7th–9th, 10th–12th and 13th–15th exercise bouts (block 1 versus 2, 3, 4 and 5).ResultsTreadmill speed was slower during block 4 (6.14 ± 0.67 versus 6.24 ± 0.73 km/h^?1) and block 5 (6.12 ± 0.64 versus 6.25 ± 0.75 km/h^?1) in HYP compared to NOR or CON (p = 0.009). Compared to NOR and CON, heart rate was +6–10% higher (p = 0.001), whilst arterial oxygen saturation (?12–13%) was lower (p < 0.001) in HYP. Perceived limb discomfort was lower in HYP and CON versus NOR (?21 ± 4% and ?34 ± 6%; p = 0.004).ConclusionsIn overweight-to-obese adults, perceptually regulated interval walks in hypoxia versus normoxia leads to progressively slower speeds along with lower limb discomfort and larger physiological stress than normoxia. Walking at the speed adopted in hypoxia produces similar psycho-physiological responses at the same absolute intensity in normoxia.

GENIPSO: a French prospective study assessing instantaneous prevalence,clinical features and impact on quality of life of genital psoriasis among patients consulting for psoriasis

Psoriasis is a common chronic inflammatory skin disease, affecting about 3% of the general population and approximately 2.5 million people in France, where this study took place. The genital area may be affected, however prevalence is poorly understood, meaning we do not know exactly how commonly this occurs. While it affects quality of life, genital psoriasis is under-recognized, probably due to the reluctance of patients to discuss genital involvement and sexual quality of life. The aims of this study, called the GENIPSO study, were to determine the prevalence of genital psoriasis, its clinical characteristics (its symptoms), whether it is associated with a particular type of psoriasis, and its impact on quality of life. The study included 776 adults seeing their doctor for psoriasis between November 2016 and March 2017. Among them, 336 (43.2%) had genital psoriasis. All these patients were aware that they had psoriasis on their genitals (genital lesions) but only 135 (40%) had already had a genital medical examination. Genital lesions were associated with (linked to) male gender, more severe psoriasis, first developing psoriasis when aged over 20 years, psoriasis of the skin folds, psoriasis on the scalp, nail and external auditory (ear) canal, but they were not associated with obesity or psoriatic arthritis. Itching was the main symptom. Genital psoriasis was associated with reduced quality of life and sexual health. The study found that genital psoriasis has a high prevalence in patients seeing their doctors about their psoriasis generally, it affects quality of life and should be better taken into account by dermatologists for the best possible care for patients.     

Complications and reoperations after surgery for 647 patients with spine metastatic disease

Background Context

Postoperative morbidity may offset the potential benefits of surgical treatment for spine metastatic disease; hence, risk factors for postoperative complications and reoperations should be taken into considerations during surgical decision-making. In addition, it remains unknown whether complications and reoperations shorten these patients' survival.
