Efficacy of Kinesio Taping and Postural Correction Exercises on Levator Scapula Electromyographic Activities in Mechanical Cervical Dysfunction: A Randomized Blinded Clinical Trial.

OBJECTIVE: Mechanical neck dysfunction (MND) is a major health burden. Although postural correction exercises (PCEs) are commonly used for its treatment, efficacy of Kinesio Taping (KT) has received considerable attention. This study was conducted to determine the effect of KT and PCEs on levator scapula (LS) electromyography. METHODS: Ninety-one patients with MND were randomly assigned into 1 of 3 groups that received 4 weeks' treatment: group A, KT; group B, PCE; and group C, both interventions. Neck pain, LS root mean square (RMS), and median frequency (MDF) were measured pretreatment and post-treatment with the Numerical Pain Rating Scale and surface electromyography, respectively, by an assessor blinded to the patients' allocation. RESULTS: Multivariate analysis of variance indicates a statistically significant group-by-time interaction (P = .000). Pain intensity was significantly reduced in group C more than in group B (P = .001). Mean values of RMS were significantly reduced in group C compared to both group A (P = .001) and group B (P = .022), whereas MDF was significantly increased in group C compared to either group A (P = .00) or group B (P = .026), and in group B compared to group A (P = 0.26). A paired t test revealed that there was a significant decrease in pain and RMS, and a significant increase in MDF in all groups (P < .01). CONCLUSION: Application of both KT and PCE combined can significantly reduce neck pain and normalize LS activities in patients with MND more than the application of either intervention.

The respective roles of modern and paleo recharge to alluvium aquifers in continental rift basins: A case study from El Qaa plain, Sinai, Egypt.

Even though assessment of aquifer characterization and recharge mechanisms in rift-related basins, especially in arid environments, is essential for developing sustainable management strategies and food security assurance, a little attention has been paid to understand these parameters. In this manuscript, we utilize an integrated remote sensing, hydrological and isotopic approach together with previously published data to better understand the aquifer characteristics and the respective roles of modern and paleo recharge to the post-Miocene alluvium aquifer in El Qaa plain, which represents the eastern margin of the Gulf of Suez continental rift basin. Our findings indicate that: (1) the alluvium aquifer is largely formed of sand and gravels intercalated with silt and clay lenses and exceeds 500 m thick, (2) the groundwater salinity gradually increases towards the Gulf of Suez (from 402 to 5613 mg/l) with increasing the distance from the crystalline rocks bounding the alluvium-dominated plain, (3) isotopic analysis reveals that all of the groundwater samples show mixed isotopic signature between modern and paleo waters (δ18O: -6.79 to -4.433‰, and δ2H: -46.36 to -21.99‰). Basin-scale hydrological parameters show that the aquifer receives an annual modern recharge of 39 × 106 m3 and isotopic mass balance calculations indicate that the modern water ranges between 20 and 70% of the total volume of water in the aquifer. We suggest three dam locations along the southernmost basins in El Qaa plain to enhance the modern recharge to the aquifer and to harvest surface runoff of an annual volume of 737 × 103 m3 sufficient to supply freshwater to 13 thousands of the residents of south Sinai. The present study suggests that topographically-driven modern recharge to rift-related basins is taking place with significant amounts even under hyper-arid conditions and calls for paying special attention to investigate the response of these aquifers to climate variability.

Impact of Early Dressing Removal on Tunneled Central Venous Catheters: A Piloting Study.

Background: Central Venous Catheters (CVC) are linked with Catheter-related bloodstream infections (CLABSI) or exit-site infections. Dressings may reduce the rate of infection, but they are uncomfortable, do not eliminate the risk of infection, and in some cases become the cause of infection. Aim: This study evaluates the impact of early CVC dressing removal on CLABSI, exit-site infections, and patient quality of life in an oncology setting. Method: A quasi-experimental pilot study was conducted over 15 months at a specialized oncology center. Sixteen patients were divided into control (n=8) and experimental (n=8) groups. The control group received the standard protocol of applying CVC dressings, while the experimental group received a "no-dressing" protocol. Results: There was no statistical significance in the infection rate between the two groups (p=1.0). Two cases developed CLABSIs, one in each group. One patient from the experimental group developed an exit-site infection as well. Patients in the experimental group reported high satisfaction and an improved quality of life. Conclusions: Applying a no-dressing protocol to a wellhealed exit site CVC showed encouraging results in terms of exit-site and bloodstream infections. That is to say; it did not predispose patients to increased risk of infections. Furthermore, patients with no dressing protocol feel more comfortable in their life.
