Leg Immersion in Warm Water,Stretch-Shortening Exercise,and Exercise-Induced Muscle Damage

Context:

Whether muscle warming protects against exercise-induced muscle damage is unknown.

Objective:

To determine the effect of leg immersion in warm water before stretch-shortening exercise on the time course of indirect markers of exercise-induced muscle damage.

Design:

Crossover trial.

Setting:

Human kinetics laboratory.

Patients or Other Participants:

Eleven healthy, untrained men (age  =  21.5 ± 1.7 years).

Intervention(s):

Participants'' legs were immersed in a water bath at 44 ± 1°C for 45 minutes.

Main Outcome Measure(s):

Creatine kinase changes in the blood, muscle soreness, prolonged (within 72 hours) impairment in maximal voluntary contraction force and height of drop jump, and electrically evoked muscle force at low and high stimulation frequencies at short and long muscle lengths.

Results:

Leg immersion in warm water before stretch-shortening exercise reduced most of the indirect markers of exercise-induced muscle damage, including creatine kinase activity in the blood, muscle soreness, maximal voluntary contraction force, and jump height. The values for maximal voluntary contraction force and jump height, however, were higher during prewarming than for the control condition at 48 hours after stretch-shortening exercise, but this difference was only minor at other time points. Muscle prewarming did not bring about any changes in the dynamics of low-frequency fatigue, registered at either short or long muscle length, within 72 hours of stretch-shortening exercise.

Conclusions:

Leg immersion in warm water before stretch-shortening exercise reduced most of the indirect markers of exercise-induced muscle damage. However, the clinical application of muscle prewarming may be limited, because decreasing muscle damage did not necessarily lead to improved voluntary performance.     

Suicidal ideation in patients undergoing brain tumor surgery: prevalence and risk factors

Purpose

Suicidal ideation (SI) is an important complication in cancer patients that should be promptly recognized and adequately managed. We investigated the prevalence rate and correlates of pre-operative SI in brain tumor (BT) patients admitted for elective BT surgery.

Methods

Two hundred and eleven consecutive patients (70 % women; mean age 55.9 ± 15.4 years) scheduled for BT surgery were evaluated for SI (“suicidal thought” item from the Beck Depression Inventory-II), depressive/anxiety symptom severity (Hospital Anxiety and Depression scale (HADS)), health-related quality of life (SF-36 scale), functional status (Barthel Index), and psychiatric histories and treatments. The majority of patients were diagnosed with meningioma (39 %) and high-grade glioma (17 %).

Results

SI was self-reported by 12 (6 %) patients. Patients expressing SI were most commonly diagnosed with meningioma (50 %). Patients with SI were more likely to have a past history of psychiatric disorders, scored higher on the HADS anxiety subscale, and reported worse health-related quality of life across physical and mental health domains. In multivariate regression analyses, worse perceived mental health was associated with increased risk for SI independently from clinical, sociodemographic, and other patient-oriented variables considered in the study.

Conclusions

SI was self-reported by 6 % of BT patients before surgical intervention and was associated with a past history of psychiatric disorders and worse perceived health status. Poor mental health was an independent correlate of SI. The perception of health status by a patient should be considered as an important determinant of poor mental health in BT patients.

Predictors of health-related quality of life in neurosurgical brain tumor patients: focus on patient-centered perspective

Background

In brain tumor (BT) patients, the association between health-related quality of life (HRQoL) and psychological characteristics remains largely unknown. We evaluated the association of personality traits, clinical factors, psychological distress symptoms, and cognitive state with HRQoL in BT patients.

Methods

On admission for BT surgery, 200 patients (69 % women; age 55.8?±?14.5 years) were evaluated for HRQoL (SF-36 scale), Big-Five personality traits (Ten-Item Personality Inventory), psychological distress symptoms (Hospital Anxiety and Depression Scale or HADS), cognitive function (Mini-Mental State Examination or MMSE) and clinical characteristics, including functional status (Barthel index or BI). The most common BT diagnoses were meningioma (39 %) and high-grade glioma (18 %).

Results

Only factors significantly associated with SF-36 domains in univariable regression analyses were included in their respective multivariable models and predicted from 6 %–49 % of the total variance of SF-36 scores. Greater TIPI emotional stability score was independently associated with greater SF-36 emotional well-being (β?=?0.23, p?<?0.001) and general health (β?=?0.18, p?=?0.01) scores, and greater TIPI consciousness score, with greater SF-36 emotional well-being score (β?=?0.13, p?=?0.02). HADS-anxiety and HADS-depression scores were the strongest independent determinants of all, except physical functioning, SF-36 scores (β-values range from 0.14 to 0.56; p values?≤?0.03). BI score was the strongest independent determinant of SF-36 physical functioning score (β?=?0.36, p?<?0.001). MMSE score was associated with all but emotional well-being and social functioning SF-36 scores.

Conclusions

Consciousness and emotional stability should be considered important personality-related determinants of HRQoL in BT patients. Psychological distress, functional disability, and cognitive impairment are also important predictors of HRQoL.
