The influence of subjective factors on temporary threshold shifts after exposure to music and noise of equal energy.

The present study examined the influence of subjective factors on temporary threshold shifts (TTS) after exposure to noise and music. Two groups of subjects, those who indicated liking and those who indicated disliking pop/rock music, were exposed to both noise and music on separate occasions. Subjects who liked the music exhibited less TTS following music than noise. They also exhibited less TTS in music than the subjects who disliked the music. Those who disliked the music evidenced greater magnitude of TTS in music than noise.

Nonlinear ultrasonic phased-array imaging method for closed cracks based on conjugate delay-multiply-and-sum and fixed-voltage fundamental wave amplitude difference.

Conventional linear ultrasonic phased-array imaging is often limited by crack closure and propagation direction, making stable, high-contrast imaging of closed fatigue cracks difficult. To address residual linear artifacts in odd-even fundamental wave amplitude difference (OE-FAD) imaging associated with system nonlinearity in some conventional phased-array instruments, this study investigates a nonlinear ultrasonic phased-array imaging method based on complex-valued correction-factor-enhanced OE-FAD. The method is combined with conjugate delay-multiply-and-sum (conj-DMAS) post-processing and …

Occupational therapy (OT) allows individuals to participate in activities of daily living (ADLs) and improves their quality of life. However, whether OT improves health-related quality of life (HRQOL), ADLs, fatigue, occupational performance, rehospitalization, and mortality in patients with CVD remains unclear. This study aimed to determine whether OT improves HRQOL, ADLs, fatigue, occupational performance, rehospitalization, and mortality in patients with CVD using a systematic review and meta-analysis. METHODS A…

The role of obesity in physiological stress, balance, and proprioception during repetitive manual material handling tasks.

Manual laborers often experience fatigue-related incidents, which increase their risk of balance disturbances and falls. Previous research indicates that obese individuals may reach critical fatigue levels during repetitive lifting. This study examines whether this BMI-based fatigue pattern also applies to other manual handling activities. Therefore, assessing balance impairment under high physiological stress conditions will help quantify the increased fall risk in obese individuals. Thirty participants performed carrying and pushing/pulling tasks, with weights determined using the Liberty Mu…

The Casual Associations Between Brain Functional Networks and Fibromyalgia: A Large-Scale Genetic Correlation and Mendelian Randomization Study.

While the central mechanisms of fibromyalgia have gained attention, the causal effects between brain networks and fibromyalgia remain unclear. Two-sample Mendelian randomization and Linkage Disequilibrium Score Regression were performed to investigate the relationship between 191 rsfMRI traits and 8 fibromyalgia-related traits. A total of 4 rsfMRI traits were genetically correlated with trouble falling asleep, 11 with back pain for 3+ months, 16 with pain all over the body, 14 with insomnia, 5 with fibromyalgia, 4 with fibromyalgia, and 3 with malaise and fatigue. Pheno801 has significant caus…

Potential predictors of quality of life in patients with venous leg ulcers: A cross-sectional study in Taiwan.

Internationally, the impact of venous leg ulcers (VLUs) on the quality of life is well recognised; however, in Taiwan, the focus is only on chronic wound management. This cross-sectional correlational study conducted at the cardiovascular and plastic surgery clinics of a regional teaching hospital between August 2019 and June 2020 investigates venous clinical severity, pain, fatigue, depression, sleep quality, quality of life, and related factors among 167 patients with VLUs. The potential predictors of the quality of life in terms of activities were venous clinical severity (P < 0.001), pain …

Do fibromyalgia patients feel older than they really are? An observational study.

OBJECTIVES: This study aimed to test the hypothesis that fibromyalgia patients feel older than their actual age and to investigate the associations between their subjective age and clinical parameters such as cognition, depression, anxiety, widespread pain, sleep, and fatigue. METHODS: This observational cross-sectional study enrolled 176 patients with newly diagnosed fibromyalgia and 89 controls. Subjective age was determined by asking the question "how old do you feel?", and the difference between the physiological and subjective ages was calculated. Depression, anxiety, fatigue, sleep cogn…

Independent and joint associations of physical activity and fitness with fibromyalgia symptoms and severity: The al-Ándalus project.

We examined independent and joint associations of objectively measured physical activity (PA) and physical fitness (PF) with pain, fatigue and the overall impact of fibromyalgia in 386 fibromyalgia women aged 51.2 ± 7.6 years. Levels of PA (light, moderate and vigorous) and PF were measured with triaxial accelerometry and the Senior Fitness Test, respectively. We used the Short-Form health survey-36 pain sub-scale and the Multidimensional Fatigue Inventory to assess pain and multiple dimensions of fatigue, respectively. The impact of fibromyalgia was studied with the Revised Fibromyalgia Impac…

Disruption of melatonin circadian rhythm production is related to multiple sclerosis severity: A preliminary study.

Sunlight can influence the immune system independently of vitamin D, such as through melatonin production in the pineal gland. Inflammatory disorders can suppress nocturnal melatonin production, but only a few studies have investigated melatonin status in multiple sclerosis (MS). We aimed to study melatonin production in association with clinical and immunological data in MS patients. Eleven treated relapsing-remitting MS (RRMS) patients and eight controls underwent neurological examination and were assessed for fatigue severity and depressive symptoms. Inflammatory cytokines were analyzed in …

Нейромускульная функция у переживших полиомиелит.

Несмотря на отсутствие документально подтвержденных объективных доказательств того, что симптомы постполиологического заболевания быстро теряют свою силу, у них есть ряд нервно-мышечных недостатков, связанных с более серьезным полиомиелитом, что может объяснить, почему они жалуются на проблемы с силой, выносливостью и усталостью местных мышц. В период острого полиомиелита лица, страдающие симптомами постполиотического заболевания, госпитализировались дольше, восстанавливались медленнее и имели электромиографические данные, свидетельствующие о более значительной потере клеток переднего рога.
