The aim of this review is to show the historical aspects of hands washing for healthy life and explains how can reduce the transmission of community-acquired infectious agents by healthcare workers and patients. This review article is prepared based on available database. The key words used were hands washing, risk assessment, hands hygiene, bacterial flora, contamination, infection, nosocomial, tap water, sanitizer, bacterial resistance, hands bacterial flora, washing methods, antiseptics, healthcare workers, healthcare personnel, from PubMed, ScienceDirect, Embase, Scopus, Web of Sciences, and Google Scholar. Data were descriptively analyzed. The insistence on hand washing has a history of 1400 years. The research results indicate that the bacteria released from the female washed hands in wet and dry condition was lower than from the male's hands with a significance level (3 CFU vs. 8 CFU; confidence interval 95%, P ≤ 0.001). The valuable results of the study indicated that released amount of bacterial flora from wet hands is more than 10 times in compared to dry hands. In addition, established monitoring systems for washing hands before and after patient's manipulation as well as after toilet were dominant indices to prevent the transfer of infectious agents to the patients. Increasing awareness and belief of the healthcare workers have shown an important role by about 30% reduction in the transfection. Hand washing could reduce the episodes of transmission of infectious agents in both community and healthcare settings. However, hand washing is an important key factor to prevent transmission of infectious agents to patients. There is no standard method for measuring compliance. Thus, permanent monitoring of hand washing to reduce the transmission of infections is crucial. Finally, the personnel must believe that hand washing is an inevitable approach to infection control.

Background:Cytokines play an important role in modulating the muscle’s metabolic and immunological responses to exercise.Objectives:In the present study, we investigated changes in the serum levels of Interleukin (IL)-15 as well as tumor necrosis factor (TNF)-α and high sensitivity C-reactive protein (hs-CRP), as markers of inflammation, in athlete and non-athlete young men following eccentric (ECC) and concentric (CON) emphasized resistance exercise (RE).Patients and Methods:This study recruited 28 young males, 14 athletes and 14 non-athletes. Subjects completed two bouts of ECC and CON emphasized RE five days apart. Each bout included seven exercises that emphasized all major muscle groups with weight loads of 70% - 80% of one repetition maximum (1RM) for CON RE and 90% - 100% of 1RM for ECC RE. We analyzed subjects’ blood samples before and immediately after each bout of exercise to determine cytokine and hs-CRP serum levels according to enzyme-linked immunosorbent assay.Results:Statistical analysis showed a significant difference between IL-15 serum levels before and after ECC and CON RE in non-athletes (P = 0.03). In athletes, IL-15 serum level only increased after ECC RE (P = 0.01), which was noted to be the highest degree of change in IL-15 levels in all subjects. For athletes, the hs-CRP levels significantly decreased (P < 0.05). The serum levels of both TNF-α and hs-CRP were also significantly down-regulated after ECC RE in non-athletes.Conclusions:These results indicated that fitness level and RE could modulate circulating levels of IL-15 and suggest the potential anti-inflammatory effects of IL-15 during RE.

Recreational athletes may listen to music or watch videos to prolong their exercise routines. In recent years, use of active videogames has increased. The effects of audiovisual encouragements have not been compared for their potential ergogenic effects on physiological variables during moderate- to high-intensity exercises. Here 60 sedentary healthy male students were divided into four groups-control (CON), audio feedback (A), videogame feedback (V), and a combination of A and V (AV)-based on previous measurement of maximum oxygen uptake using covariate adaptive randomization. Participants completed a bout of running (Balke treadmill test) until exhaustion based on the type of feedback. Exercise responses (time, heart rate, blood sugar level, and creatine kinase level) were compared in all groups before and after participation. Participants in group A ran significantly more than those in the CON group, and those in group AV ran significantly more than those in groups CON and V. In other physiological responses, the differences were not significant among groups. It is proposed that intentional functions from internal (physical feelings) to external perspective (music and video) may have been involved in increasing exercise time but were not strong enough to change levels of other physiological parameters. However, these findings have strong applications for improving fitness exercise programs while using a new generation of videogames.

Introduction: Using non-medical methods such as exercise can be effective for reducing the number of physical and mental disorders that occur after kidney transplantation. The present study aimed to investigate the effectiveness of a period of regular physical activity of choice as a non-medical method for reducing blood pressure, stress, anxiety and depression in patients with kidney transplants. Materials & Methods: Fifty kidney transplant patients (21 males and 29 females) volunteered as the study subjects and were randomly divided into two groups-an exercise group (n=30) and a control group (n=20). The exercise group partook in a progressive exercise program for ten weeks with three sessions of 60-90 minutes each week while the control group did not partake in any regular physical activityPsychological data of participants as well as their blood pressure before and after the 10-week period were collected using the DASS21 questionnaire. Data were analyzed using descriptive statistics and the t-test with the gain score method. Results: Exercise significantly reduced stress, anxiety and depression (P<0.001) as well as systolic blood pressure (P=0.007) in the exercise group compared to the control group. Conclusion: 1Partaking in ten weeks of a light-intensity exercise of choice can improve stress , anxiety and depression and control blood pressure in patients with kidney transplants.
