Trait mindfulness and the mental and physical health of caregivers for individuals with cancer.

BACKGROUND: Mindfulness plays a role in moderating the negative mental and physical health outcomes associated with caregiving. The aims of this study were to examine the relationship between trait mindfulness and the (1) psychological functioning, (2) health behaviors, (3) and physical health of caregivers for individuals diagnosed with cancer. METHODS: Caregivers completed a battery of questionnaires and examinations assessing sociodemographic characteristics, trait mindfulness, depression, perceived stress, caregiver stress, sleep, diet, physical activity, tobacco use, alcohol use, blood pressure, and BMI. Demographics and cancer diagnostics were collected for the individuals whom caregivers supported. Linear regression, multivariate analyses, and moderator analyses were performed. RESULTS: Of the 78 caregivers, the mean age was 63.9 (S.D.=13.1); 59% identified as female; 97% identified as White. Regression analyses indicated that caregivers who reported higher levels of trait mindfulness reported significantly less perceived stress (b= -4.38, SE= 0.88, p <.001), lower levels of depression (b= -3.74, SE= 1.10, p = .001), greater caregiver quality of life (b= -9.05, SE=2.12, p < .001), better sleep quality (b= -0.98, SE=0.44, p = 0.03), and lower rates of tobacco use (b= -10.12, SE= 3.43, p =.003). Trait mindfulness was not significantly related to diet, alcohol use, blood pressure, or BMI. CONCLUSIONS: Higher levels of trait mindfulness are associated with positive mental and physical health measure for caregivers. Future research would benefit from further examining mindfulness-based interventions and their impacts in mitigating the negative toll of caregiving in the context of cancer.

High-mobility group box-1 in sterile inflammation.

High-mobility group box 1 (HMGB1) was originally defined as a ubiquitous nuclear protein, but it was later determined that the protein has different roles both inside and outside of cells. Nuclear HMGB1 regulates chromatin structure and gene transcription, whereas cytosolic HMGB1 is involved in inflammasome activation and autophagy. Extracellular HMGB1 has drawn attention because it can bind to related cell signalling transduction receptors, such as the receptor for advanced glycation end products, Toll-like receptor (TLR)2, TLR4 and TLR9. It also participates in the development and progression of a variety of diseases. HMGB1 is actively secreted by stimulation of the innate immune system, and it is passively released by ischaemia or cell injury. This review focuses on the important role of HMGB1 in the pathogenesis of acute and chronic sterile inflammatory conditions. Strategies that target HMGB1 have been shown to significantly decrease inflammation in several disease models of sterile inflammation, and this may represent a promising clinical approach for treatment of certain conditions associated with sterile inflammation.

Coalescent mastoiditis in a child with severe congenital neutropenia. Report of a case.

This is a report of a case of coalescent mastoiditis seen in a 3-year-old child with severe congenital neutropenia. Pseudomonas aeroginosa was the main bacterial species recovered from the affected ear. Modified radical mastoidectomy was done and appropriate antibiotics administered. Operative wound infection with delayed wound healing was the hallmark of the postoperative follow-up period. Large spectrum oral antibiotics in addition to regular wound cleansing was an effective adjunct to therapy. On last follow-up operative wound was healed and mastoid cavity was clean. Occurrence, treatment, clinical and microbiological aspects of coalescent mastoiditis were described and discussed.

Natural history of scoliosis in Friedreich's ataxia.

Does scoliosis associated with Friedreich's ataxia behave like an idiopathic or a typical neuromuscular scoliosis? Should it be treated like an idiopathic or a neuromuscular curve? Since no precise information to answer these questions could be found in the orthopaedic literature, a retrospective study was undertaken of seventy-eight patients with Friedreich's ataxia who had been followed at our neuromuscular clinic. Fifty-six of these patients were found to have typical Friedreich's ataxia in accordance with the criteria of Geoffroy et al., and their cases were retained for analysis. Their mean age was twenty years (range, eight to thirty-three years). The average length of clinical follow-up was nine years and the average duration of radiographic follow-up of the scoliosis was 3.5 years. A scoliosis of more than 10 degrees was found in all patients and was associated with a hyperkyphosis in 66 per cent. Both sexes were equally affected. Fifty-seven per cent of the curves were double thoracic and lumbar; 14 per cent were thoracolumbar; 7 per cent, double thoracic and thoracolumbar; 7 per cent, thoracic; 4 per cent, lumbar; and 11 per cent, multiple small curves. Of the fifty-six patients whose cases were studied, thirty-six had been followed for at least ten years. Among these thirty-six, there were twenty whose curves were more than 60 degrees and progressed (Group I) and sixteen whose curves were 40 degrees or less and did not progress (Group II).(ABSTRACT TRUNCATED AT 250 WORDS)

[Bacteria endocarditis of dental origin with neurological complications]. / Endocardite bactérienne d'origine dentaire avec complications neurologiques.

A 49 years old man suffered from transient hemiplegic episodes following bacterial endocarditis, cultures being negative and with a fever resistant to antibiotics. Complete stomatological evaluation revealed multiple dental infective sites constituting "portals of entry". Radical treatment of these sites contributed to the complete cure of the infective syndrome.
