Physiological Signal

Abstract Cell phones produce electromagnetic interference (EMI), which can cause artifacts in physiological recordings and be misinterpreted by the clinician. This study investigated the possible effect of EMI (electrical artifact) on physiological recordings when cell phones are activated/ringing. The procedure consisted of placing the cell phone at varying distances from surface electromyographic sensors. Depending on the orientation of the cell phone's antenna, the EMI produced an artifact in the physiological signal for up to 175 cm (6 ft) that can be misinterpreted by the therapist. To avoid EMI artifacts, clients and therapists should turn off their cell phones when recording physiological signals. This means turning the cell phone off and not just switching it to vibrate. In addition, recent epidemiological studies suggest that long-term intensive cell phone use may increase the risk of gliomas, auditory tumors, and salivary tumors on the side of the head to which the person places the cell phone. Thus, to reduce artifacts and biological harm, the authors recommend keeping the cell phone away from the body and the biofeedback equipment.

BACKGROUND Cell phone use brought convenience to people, but using phones for a long period of time or in the wrong way and with a wrong posture might cause damage to the human body. OBJECTIVE To assess the impact of improper cell phone use on transport and chronic injuries. METHODS Studies were systematically searched in PubMed, EMBASE, Cochrane, and Web of Science up to April 4, 2019 and relevant reviews were searched to identify additional studies. A random-effects model was used to estimate the overall pooled estimates. RESULTS Cell phone users were at a higher risk for transport injuries (RR: 1.37, 95%CI: 1.221.55), long-term use of cell phones increased the transport injury risk to non-use or short-term use (RR: 2.10, 95% CI: 1.632.70). Neoplasm risk caused by cell phone use was 1.07 times that of non-use (95% CI: 1.011.14); Compared with non-use, cell phone use had a higher risk of eye disease, with a risk of 2.03 (95% CI: 1.273.23), the risk of mental disease was 1.26 (95% CI: 1.171.35), the risk of neurological disorder was 1.16 (95% CI: 1.021.32), and a pooled risk of other chronic injuries was 1.20 (95% CI: 0.981.59). CONCLUSIONS Cell phone use at inappropriate situations has a negative impact on the human body. Therefore, it is necessary to use cell phones correctly and reasonably.

Abstract Background Cell phone use brought convenience to people, but using phones for a long period of time or in the wrong way and with a wrong posture might cause damage to the human body. This study was designed to assess the impact of cell phone use on transport and chronic injuries.Methods Studies were systematically searched in four database and relevant reviews were searched to identify additional studies. A total of 41 studies met the inclusion criteria.Results Cell phone users were at a higher risk for transport injuries (RR: 1.37, 95%CI: 1.22−1.55), long-term use of cell phones increased the transport injury risk to non-use or short-term use (RR: 2.10, 95% CI: 1.63−2.70). Neoplasm risk caused by cell phone use was 1.07 times that of non-use (95% CI: 1.01−1.14); Compared with non-use, cell phone use had a higher risk of eye disease, with a risk of 2.03 (95% CI: 1.27−3.23), the risk of mental disease was 1.26 (95% CI: 1.17−1.35), the risk of neurological disorder was 1.16 (95% CI: 1.02−1.32), and a pooled risk of other chronic injuries, was 1.20 (95% CI: 0.98−1.59). Subgroup analyses found that motor crashes had significantly increased (OR: 1.25; 95%CI: 1.18−1.32), as well as the risk for hearing problems (OR: 4.54; 95%CI: 3.29−5.80), headaches (OR: 1.25; 95%CI: 1.18−1.32), and abnormal biochemical indicators (OR: 0.51; 95%CI: 0.04−0.99).Conclusions Cell phone use at inappropriate situations has a negative impact on the human body. Therefore, it is necessary to use cell phones correctly and reasonably.

Introduction: Food is a carrier of many pollutants nowadays. For cadmium and dioxins, it is the main source of these compounds in the general population. Hence, the aim of this work was to collect data on the health effects associated with exposure to cadmium and dioxins which get into the human body through food.Materials and methods: A literature review was conducted by searching the scientific Medline database (PubMed) and Google Scholar.Results: Health effects associated with a long-term exposure to low doses of cadmium and dioxins may be nonspecific and are rarely attributed to food sources. These may cause disorders affecting hormonal balance, kidney function, lipid metabolism, fertility, cognitive function, bone mineralization, and susceptibility to diseases and allergies. These compounds may also lead to cancer development.Conclusions: The general population faces the problem of longterm exposure to small doses of these substances due to their accumulation in the body, even if their amounts do not exceed the relevant standards. The health effects of this type of exposure may be significantly delayed and are not likely to be attributed to the consumption of contaminated food. Consumers wishing to reduce the amounts of these compounds delivered to the body should limit the consumption of grilled and smoked products, and should also opt for organic food.

Long Term Prognosis

Obesity is one of the 10 risk factors of death. Many epidemiological studies have shown that overweight and obesity are associated with 44% cases of diabetes type 2, and 23% of cases of coronary heart disease. The body mass index (BMI) is traditionally a diagnostic marker of obesity and overweight are considered. However, in the last 15 years, there has been work on the «paradox» of obesity. So the obese long-term prognosis and stroke are more favorable than individuals without excess weight and obesity. A deeper analysis of the data showed that the highest risk of developing cardiovascular disease and disorders of carbohydrate metabolism associated with visceral obesity. This is largely due to metabolic disorders occurring on the background of visceral obesity, such as insulin resistance, hyperglycemia, dyslipidemia, an imbalance of adipokines and markers of inflammation. These changes in individuals with visceral obesity can occur regardless of the value of BMI.

Driver Distractions

Despite increased media attention and legislation banning some forms of cell phone use while driving, drivers continue to engage in illegal cell phone distractions. Several studies have used the theory of planned behavior (TPB) to explain why drivers voluntarily engage in cell phone distractions, and found that TPB constructs (attitudes, social norms, perceived behavioral control) predict intentions to engage in cell phone distractions while driving. Given that cell phone use is ubiquitous, habits that have formed around their general use may lead to automatic engagement in cell phone distractions while driving. This differs from voluntary engagement, in that habits are carried out automatically, with little thought given to the action or its consequences. Thus, in addition to the TPB constructs that explain intentions, habitual factors should also be considered in understanding why drivers use cell phones. A few studies have examined the role of habits in this context, but they only focused on texting behaviors. An online survey was conducted with 227 respondents to investigate the role of habitual cell phone use in driver engagement in a variety of illegal cell phone tasks (e.g., social media, email). Habitual cell phone use was found to explain unique variance in self-reported engagement after controlling for TPB constructs. Overall, the findings indicate that cell-phone-related distractions may not be entirely voluntary; instead, cell phone habits developed outside of the driving context appear to have a significant effect, suggesting that cell phone use while driving may have become automatic to a certain extent.

Whether it is hand held, in a pocket, on a backpack, clipped to a belt, or hidden in a brief case or purse, college students and cellular telephones go together.  Communication with fellow students, professors, parents, and everyone else is just a click away. While walking across campus and down the halls of academic buildings, cellular telephones are being used.  This research questions in what ways do students use cellular telephones and does this use interfere with or assist in learning and college life?  This paper reports the results of a survey of undergraduate business students addressing this question.  The objectives were to determine: (1) how much time is spent using a cell phone and which phone features are used most frequently, (2) what students believe concerning the impact of cell phones on learning in the classroom and during study, (3) how often students are in contact with parents on a cell phone, and (4) how much do students pay for cell phone services.  The results indicate that 100% of the students own a cell phone.  Sixty-six percent of the students use voice calls most frequently and 30% use text messages most often.  A total of 55.8% of students report that they spend 3 hours or less on their cell phone daily and 44.8% spend four or more hours daily on their cell phones.  Over half of the students report that they have some interaction with their cell phones during class time for every class.  Seventy-seven percent state that this cell phone use seldom or never interferes with classroom learning. All of the students (100%) believe that they should be able to receive emergency information over a cell phone during class time.  Seventy-six percent believe that cell phones seldom or never assist in classroom learning.  However, students report that cell phone use impacts on study time outside of class.  Cell phone distractions during study time outside class was reported by 34.6% of the students as happening often or always and an additional 43.5% are sometimes distracted by cell phones during study time. Bad or upsetting news received over a cell phone before class impacts academic performance of 14.2% of the students often or always.  Thirty-five percent of the students talk to parents more than once a day and another 23.7% have contact on a daily basis. Therefore, 59.5% report that they have contact with their parents at least once a day.    Fifteen percent of the students pay over $100 per month for cell phone service, 28% pay from $75 to $100, 34% spend $51 to $75, and 14% spend $26 to $50 per month.  More than 90% of the students report that they have text messaging, calculator, clock, calendar, and appointment reminder on their cell phone.  Over 70% have the internet and games.  Over 60% have a camera and email.  Only 13% have an MP3 music player and 7% have an FM radio.
