A low-cost IoT multi-spectral acquisition device.

Color and lighting quality assessment allow users to reliably examine the quality of light sources and the changes in the lighting conditions. Technological advance has led to an increase in the development of intelligent systems that are permanently connected to the Internet and that allow access to real time-data. Smart lighting systems have become a subject of great interest given their potential in different application areas, such as optimization for object reflectance and damage reduction to artwork. It has become necessary to develop new sensors that are aligned with the technological needs, that are easily integrated into IoT (Internet of Things) or smart lightning systems, and that allow estimating lighting quality measurements in real time. Here, a low-cost IoT multi-spectral acquisition device with wireless communication is presented. Insights into the overall system design and a validation of its operation is provided to allow reproducibility and independent testing of the proposed device. The device can be used for light source spectrum recovery and estimation of light quality and color rendering measures. The total cost of the device is below 130 USD, and customizability provides a great advantage over commercially available devices.

Sleep quality in fibromyalgia and rheumatoid arthritis: associations with pain, fatigue, depression, and disease activity.

OBJECTIVES: The aim of this study was to compare the sleep quality in patients with rheumatoid arthritis (RA) and fibromyalgia syndrome (FMS); and to evaluate the relationship between sleep quality and pain, fatigue, depression, and disease activity in patients with RA and FMS. METHODS: Forty RA, 40 FMS and 40 healthy controls were enrolled in the study. Disease activity and disease duration were reported in patients. Pain by visual analogue scale (VAS), fatigue by Multidimensional Assesment of Fatigue (MAF), depression by Beck Depression Index (BDI), and sleep quality by Pittsburgh Sleep Quality Index (PSQI) were gathered in all participants. RESULTS: All participants were aged between 20 and 65 years, with a mean age of 42.97±10.75 years. There was no significant difference with respect to demographic characteristics among the three study groups. Patients reported more depression than controls, but BDI scores were similar in FMS and RA patients. VAS pain scores and MAF scores were significantly different in the three groups (p<0.001). FMS and RA patients had poor sleep quality (p<0.001). FMS patients had daytime dysfunction due to sleep disorder and had worse habitual sleep efficiency than RA patients (p<0.05). In patients, positive correlations were found between PSQI and clinic assessment variables except disease duration. CONCLUSIONS: FMS and RA may have poor sleep quality when compared to subjects without rheumatologic disorders. The quality of sleep can be impaired by pain, fatigue, depression, and disease activity in such patients.

Frequency of juvenile fibromyalgia syndrome in children with familial Mediterranean fever: effects on depression and quality of life.

OBJECTIVES: To determine the prevalence of juvenile fibromyalgia syndrome (JFMS) in children with familial Mediterranean fever (FMF) and to evaluate quality of life (QoL) and depression. METHODS: Ninety-one FMF patients (M/F: 44/47) who fulfilled the Livneh criteria and 60 healthy children (M/F: 27/33) were enrolled in the study. Yunus and Masi's criteria were used for diagnosis of JFMS. Depression was assessed with Children's Depression Inventory (CDI) and QoL was evaluated with child and parent reports of Paediatric Quality of Life Inventory 4.0 (PedsQL™). RESULTS: While 20 (21.9%) of 91 FMF patients fulfilled JFMS criteria, 2 (3.3%) of the control group met the diagnostic criteria of JFMS (p=0.002). PedsQL™ scores (child self-report and parent-report) of the FMF patients were significantly lower and the depression scores were significantly higher than the healthy controls (p<0.001 for all). When the FMF patients were assigned to two groups as FMF with or without JFMS, patients with JFMS were found to have a higher depression score (p=0.007) and child and parent reports of PedsQL™ 4.0 were lower in the children with JFMS than in the patients without JFMS (p=0.001, p=0.003, respectively). CONCLUSIONS: We have determined that JFMS frequency was higher in children with FMF and patients with FMF and JFMS had a poor QoL and were more susceptible to depression. FMF patients with widespread and persistent pain should be evaluated for JFMS in order to avoid unnecessary investigations and inappropriate treatment.

Does short-wave diathermy increase the effectiveness of isokinetic exercise on pain, function, knee muscle strength, quality of life, and depression in the patients with knee osteoarthritis? A randomized controlled clinical study.

BACKGROUND: Knee osteoarthritis (OA) is a painful condition causing disability and muscle weakness. Shortwave diathermy (SWD) is one of several physical therapy modalities and used predominantly as a pain reduction modality in the clinical practice. However, the efficacy of SWD in knee OA is still inconclusive. AIM: The aim of this study was to determine if SWD increase the effectiveness of isokinetic exercise on pain, function, muscle strength, quality of life and depression in patients with OA. DESIGN: This was a randomised, controlled clinical trial. SETTING: Inpatient Physiotherapy Department. POPULATION: Forty women aged between 42 and 74 years, with a diagnosis of bilateral primary knee OA. METHODS: Patients were sequentially randomized into two groups. Group 1 (N.=20) received SWD and isokinetic muscular strengthening exercises. Group 2 (N.=20) served as control group and they received isokinetic exercises only. Both of the programs were performed three days a week, for a duration of four weeks, and a total of 12 sessions. Patients were assessed before treatment (BT), after treatment (AT), and at a three-month follow-up (F). Outcome measures included visual analogue scale, Western Ontario and McMaster University Osteoarthritis Index, six minute walking distance, isokinetic muscle testing, Short Form 36 and Beck depression index. RESULTS: The patients with OA in each group had significant improvements in pain, disability, depression, walking distance, muscle strength, and quality of life AT and F when compared with their initial status (P<0.05). There was no statistically significant difference between the groups according to all the parameters regarding the change scores between AT-BT test and F-BT test (P>0.05) except some isokinetic peak torque measurements (F-BT scores of extension right 60°, 120° and flexion right 60°). CONCLUSION: Use of SWD in addition to isokinetic exercise program seems to have no further significant effect in terms of pain, disability, walking distance, muscle strength, quality of life and depression in patients with knee OA. CLINICAL REHABILITATION IMPACT: Considering the time and cost of combination therapy is now, the isokinetic exercise program, as it is efficient, may be preferable for the treatment of knee OA, alone.
