Ulnar Nerve Entrapment Among Cell Phone Users: Cell Phone Elbow (Cubital Tunnel Syndrome).

Introduction Cell phone usage has tremendously increased, and to make usage comfortable, accessories such as Bluetooth earphones are available. But still, most people use cell phones for a long period of time by flexing their elbows near their ears. When the users flex the elbow to hold the phone near the ear, this results in increased pressure over the ulnar nerve since the ulnar nerve runs superficially at the level of the elbow. The extensive pressure over the ulnar nerve may result in nerve compression, which results in cubital tunnel syndrome, recently called the cell phone elbow. Hence, this study was undertaken to assess the ulnar nerve function among cell phone users in relation to the duration of usage. Materials and methods Young healthy volunteers (n = 30) aged between 20 and 25 years were selected for the study in order to prevent age-related neuropathic changes. After getting a history of mobile phone usage, the subjects were asked about neural symptoms such as tingling, numbness, and pain while using cell phones. Ulnar nerve function was assessed by Froment's sign and Wartenberg's sign. An ulnar nerve conduction study was done. Results Seventy percent of the subjects (n = 21) out of the 30 subjects participating in the study reported tingling and numbness during mobile phone usage. But Froment's sign and Wartenberg's sign were negative for all the subjects. There was a significant positive correlation (r = 0.913 and r = 0.8253) between the duration of mobile phone use and latency and a negative correlation (r = -0.8439) with conduction velocity. Conclusion The malposition of the elbow during prolonged cell phone use results in ulnar nerve entrapment. The continuous usage of cell phones without rest by flexing the elbow causes nerve compression. This can be taken as a warning sign to prevent further damage.

Prevalence and genetic characteristics of Staphylococcus aureus isolates from cell phones of medical students from Iran.

Although mobile phones as a rapid communication vehicle can lead to improved quality of healthcare, they can also facilitate the transmission of pathogens to patients. This current research focuses on genetic diversity, and genes involved in resistance and biofilm production of Staphylococcus aureus isolates from mobile phones of medical students. Antibiotic resistance profiling and polymerase chain reaction (PCR) amplification of antibiotic resistance and biofilm-related genes were investigated and statistically analyzed. Staphylococcal cassette chromosome mec (SCCmec) types were analyzed by multiplex PCR, and S. aureus protein A gene typing (spa typing) was done using PCR and sequencing. Sixty-four S. aureus isolates (16.8%) were obtained from 380 medical students' mobile phones who were working in hospitals. The findings showed that 71.9% of the isolates were MRSA and 78.1% were classified as MDR. All isolates exhibited sensitivity to vancomycin and linezolid. Overall, 7.8% of the isolates displayed an inducible clindamycin resistance phenotype, while 26.7% showed resistance to mupirocin. The results indicated that 68.8% of the isolates were biofilm producers, with 7 isolates (15.9%) classified as strong producers, 22 isolates (50%) as moderate producers, and 15 isolates (34.1%) as weak producers. The most prevalent type was CC8-MRSA III/t030 (18.7%), followed by CC8-MRSA III/t037 (12.5%), CC/ST22-MSSA/t790 (10.9%), CC1-MRSA IV-t114 (9.4%), CC1-MRSA IV-t127 (7.8%), CC8-MRSA V/t064 (7.8%), CC/ST15-MSSA-t360 (7.8%), CC30-MSSA/t021(6.3%), MRSA V-t355 (6.3%), CC8-MRSA III/t421 (4.7%), CC1-MRSA V-t267 (4.7%), and CC/ST15-MSSA-t084 (3.1%). The genetic diversity and prevalent multidrug resistance indicate that the resistance situation of S. aureus recovered from mobile phones in Tehran is severe, posing a potential threat to patients, the community, and healthcare settings.

Construction of influencing factor segmentation and intelligent prediction model of college students' cell phone addiction model based on machine learning algorithm.

Mobile phone addiction among college students has emerged as a prevalent phenomenon in contemporary society, posing significant challenges to the development and well-being of these individuals. The assessment of the extent of mobile phone addiction has become an urgent concern in the present context. This study employed a sample of 3000 college students from a public university in Zhejiang Province, China, to gather questionnaire data. By utilizing a machine learning algorithm, we identified the most salient factors associated with college students' addiction, with perfectionism emerging as the primary influencer. Additionally, a machine learning-based prediction model for college students' cell phone addiction was developed, yielding a prediction accuracy of 76.68%. This intelligent model can serve as a reliable tool for subsequent evaluations of college students' cell phone addiction.

Cell Phones in the OR: A Cross-Sectional Study of Norwegian Perioperative Nurses' Knowledge, Practice, and Attitudes.

Few studies have focused on the use of cell phones in the OR. In Norway, researchers sought to assess perioperative nurses' knowledge, practice, and attitudes associated with cell phone use in the OR and distributed a nationwide questionnaire via a social media platform. More than 80% of the 332 respondents thought that cell phones were contaminated and that pathogens could contaminate hands. Almost all respondents brought their phone to work; approximately 61% of respondents carried it in their pocket in the OR. Responses to questions about phone cleaning showed that 39 (11.7%) of the respondents routinely cleaned their phone before entering the OR and 33 (9.9%) of the respondents cleaned it when leaving the OR. Less than 20% of respondents indicated their facility had guidelines for cleaning personal cell phones. Opportunities for improvement in cell phone cleaning in ORs exist and additional research involving all perioperative team members is needed.

Propiedades psicométricas de la “Escala de percepción del riesgo para el uso de la tecnología” en niños y adolescentes / Psychometric properties of the “Risk perception scale for the use of technology” in children and adolescents

Los objetivos de esta investigación son: 1) crear un instrumento válido y fiable que permita evaluar la percepción del riesgo que tienen del uso de la tecnología (móvil, Internet y videojuegos) niños y adolescentes; y 2) analizar la frecuencia con la que se dan algunas conductas de riesgo en función de la percepción, el uso de la tecnología y la edad. 807 niños y adolescentes de la provincia de Córdoba (España) respondieron una batería ad hoc que recoge información sobre datos sociodemográficos; uso problemático del móvil, internet y videojuegos; y percepción de riesgo con la “Escala de percepción del riesgo del uso de la tecnología para niños y adolescentes” (EPRUT). Los resultados indican que a partir del análisis factorial, la EPRUT cuenta con tres dimensiones que hacen referencia al móvil, Internet y videojuegos. Se han observado diferencias en función de la edad y la percepción de riesgo. Evaluar la percepción del riesgo favorecerá la detección y el desarrollo de programas de prevención de uso de la tecnología en niños y adolescentes.(AU)

The aim of this work is 1) to create a valid, reliable instrument with which toevaluate the risk perception of children and adolescents regarding their use oftechnology (cell phones, Internet, and video games); and 2) to analyze thefrequency with which some risk behaviors occur in relation to perception,technology use and age. 807 children and adolescents from the province ofCordoba (Spain) answered an ad hoc questionnaire with several instruments:sociodemographic data; problematic use of cell phones, Internet, and video games;and risk perception with the Scale on Risk Perception of Technology Use forchildren and adolescents (SRPTU). The results obtained from the factor analysisreveal that the RPSTU has three dimensions, related to cell phones, Internet, andvideo games, respectively. Differences were observed in the relationship betweenage and risk perception, with older people having the highest risk perception.Assessing risk perception will favor the detection and development of preventionprograms for the use of technology in children and adolescents.(AU)

Mobile phone specific radiation disturbs cytokinesis and causes cell death but not acute chromosomal damage in buccal cells: Results of a controlled human intervention study.

Several human studies indicate that mobile phone specific electromagnetic fields may cause cancer in humans but the underlying molecular mechanisms are currently not known. Studies concerning chromosomal damage (which is causally related to cancer induction) are controversial and those addressing this issue in mobile phone users are based on the use of questionnaires to assess the exposure. We realized the first human intervention trial in which chromosomal damage and acute toxic effects were studied under controlled conditions. The participants were exposed via headsets at one randomly assigned side of the head to low and high doses of a UMTS signal (n = 20, to 0.1 W/kg and n = 21 to 1.6 W/kg Specific Absorption Rate) for 2 h on 5 consecutive days. Before and three weeks after the exposure, buccal cells were collected from both cheeks and micronuclei (MN, which are formed as a consequence of structural and numerical chromosomal aberrations) and other nuclear anomalies reflecting mitotic disturbance and acute cytotoxic effects were scored. We found no evidence for induction of MN and of nuclear buds which are caused by gene amplifications, but a significant increase of binucleated cells which are formed as a consequence of disturbed cell divisions, and of karyolitic cells, which are indicative for cell death. No such effects were seen in cells from the less exposed side. Our findings indicate that mobile phone specific high frequency electromagnetic fields do not cause acute chromosomal damage in oral mucosa cells under the present experimental conditions. However, we found clear evidence for disturbance of the cell cycle and cytotoxicity. These effects may play a causal role in the induction of adverse long term health effects in humans.

Protocol: Prospective evaluation of feasibility, added value and satisfaction of remote digital self-assessment for mild cognitive impairment in routine care with the neotivCare app.

INTRODUCTION: Timely diagnosis of mild cognitive impairment (MCI) in Alzheimer's disease is crucial for early interventions, but its implementation is often challenging due to the complexity and time burden of required cognitive assessments. To address these challenges, the usability of new unsupervised digital remote assessment tools needs to be validated in a care context. METHODS AND ANALYSIS: This multicentric healthcare research evaluation survey, re.cogni.ze, aims to evaluate physician satisfaction with a remote digital assessment solution (neotivCare) in primary and specialised routine care in Germany. Over a period of 22 months, physicians in different regions of Germany will recommend the application (app) to approximately 1000 patients for a 12-week self-assessment of cognition. The primary endpoint is the evaluation of physicians' and patients' overall satisfaction with neotivCare and with neuropsychological questionnaires/standard procedures using a Likert scale, while secondary endpoints include user-friendliness, qualitative assessment of acceptance and potential improvements on medical routine services. The study also aims to evaluate the proportion of physicians or patients attributing added value to neotivCare compared with standard paper-pencil tests. The study results will provide insights into the feasibility, efficiency and acceptance of new digital tools for MCI diagnosis in routine care. The re.cogni.ze survey will thus provide proof-of-concept information for the implementation of remote digital cognitive assessment apps for MCI into medical routine care. ETHICS AND DISSEMINATION: This study was approved by the ethics committee of the State Medical Association (Landesärztekammer) Baden-Württemberg, (F-2021-161) as the leading committee and nine ethics committees local to the participating healthcare professionals (Lower Saxony, North Rhine, Westphalia-Lippe, Hesse, Bremen, Berlin, University of Göttingen, Charite, University of Rostock). The results can be shared (upon reasonable quest) to improve routine clinical processes and holistic approaches.

Is having your cell phone the key to happiness, or does it really matter? Evidence from a randomized double-blind study.

BACKGROUND: Affect can influence people's perceptions, decisions, and the way they make sense of an experience. Some studies show that having one's cell phone removed will lead to negative emotional reactions, while others have found no significant impact on how we feel. In this paper we investigate the impact of cell phone possession and removal on participant's affective state. METHODS: We use a randomized double-blind procedure to examine whether cell phone removal enhances negativity, promotes positivity, or is emotionally inconsequential. We measure affect using a PANAS self-report scale as well as a less transparent temporal-estimation procedure. RESULTS: Our findings suggest that cell phone possession or removal has no influence on a person's affective state. CONCLUSIONS: Measured through both the PANAS self-report scale and temporal estimation task, affect remained consistent regardless of cell phone possession. These results suggest that cell phones may not carry the emotional weight often attributed to them. This finding challenges a common theme revolving around the negative emotional impact of cell phones and technology. Consequently, these findings may have important implications for the generally perceived notion that cell phones are having a negative effect on people's emotions.

"It's okay because I'm just driving": an exploration of self-reported mobile phone use among Mexican drivers.

Introduction: Technological advancements have the potential to enhance people's quality of life, but their misuse can have a detrimental impact on safety. A notable example is the escalating issue of distracted driving resulting from the use of mobile phones behind the wheel, leading to severe crashes and injuries. Despite these concerns, both drivers' usage patterns and their risk-related associations remain scarcely documented in Mexico. Therefore, this descriptive study aimed to examine the mobile phone usage of Mexican drivers, its relationships to risk awareness and near-miss/crash involvement, and the self-reported underlying reasons for this behavior. Methods: This cross-sectional study utilized a sample of 1,353 licensed Mexican drivers who took part in a nationwide series of interviews regarding their onboard phone use settings. Results: A significant percentage of drivers (96.8%) recognize using a mobile phone while driving as high-risk behavior. However, only 7.4% reported completely avoiding its use while driving, with 22.4% identified as high-frequency users. Frequency was also found positively associated with the self-reported rate of near-misses and crashes. Furthermore, qualitative data analysis highlights the emergence of a 'sense of urgency' to attend to phone-related tasks in response to daily demands and life dynamics, offering a potential explanation for this behavior. Conclusion: The results of this study suggest common patterns of onboard mobile use among Mexican drivers concerning driving situations and associated risks. This underscores the need for increased efforts to discourage onboard phone use in the country.

Engaging and following physical injury survivors at risk for developing posttraumatic stress disorder symptoms: A 25 site US national study.

INTRODUCTION: Early intervention for patients at risk for Posttraumatic Stress Disorder (PTSD) relies upon the ability to engage and follow trauma-exposed patients. Recent requirements by the American College of Surgeons Committee on Trauma (College) have mandated screening and referral for patients with high levels of risk for the development of PTSD or depression. Investigations that assess factors associated with engaging and following physically injured patients may be essential in assessing outcomes related to screening, intervention, and referral. METHODS: This investigation was a secondary analysis of data collected as part of a United States level I trauma center site randomized clinical trial. All 635 patients were ages ≥18 and had high PTSD symptom levels (i.e., DSM-IV PTSD Checklist score ≥35) at the time of the baseline trauma center admission. Baseline technology use, demographic, and injury characteristics were collected for patients who were followed up with over the course of the year after physical injury. Regression analyses were used to assess the associations between technology use, demographic and injury characteristics, and the attainment of follow-up outcome assessments. RESULTS: Thirty-one percent of participants were missing one or more 3-, 6- or 12-month follow-up outcome assessments. Increased risk of missing one or more outcome assessments was associated with younger age (18-30 versus ≥55 Relative Risks [RR] = 1.78, 95 % Confidence Interval [CI] = 1.09, 2.91), lack of cell phone (RR = 1.32, 95 % CI = 1.01, 1.72), no internet access (RR = 1.47, 95 % CI = 1.01, 2.16), public versus private insurance (RR = 1.47, 95 % CI = 1.12, 1.92), having no chronic medical comorbidities (≥4 versus none, RR = 0.28, 95 % CI = 0.20, 0.39), and worse pre-injury mental health function (RR = 0.99, 95 % CI = 0.98, 0.99). CONCLUSIONS: This multisite investigation suggests that younger and publicly insured and/or uninsured patients with barriers to cell phone and internet access may be particularly vulnerable to lapses in trauma center follow-up. Clinical research informing trauma center-based screening, intervention, and referral procedures could productively explore strategies for patients at risk for not engaging and adhering to follow-up care and outcome assessments.

Cell phone distraction behavior of young pedestrians: evidence from China.

Cell phone use while walking escalates pedestrian safety risks, particularly among students, given their heavy reliance on these devices. Psychological factors wield significant influence on individual behavior, particularly among adolescents who navigate a blend of rational and social-reactive pathways in decision-making. Therefore, this paper employs the Prototype Willingness Model (PWM) to scrutinize psychological determinants of students' cell phone use while walking, drawing on data from 368 valid samples. Structural equation modeling (SEM) dissects the impact of psychological constructs on this behavior, highlighting the significance of both the social response and reasoning pathways within PWM. The study comprehensively analyzes direct, indirect, and overall effects of exogenous variables on behavioral intention and behavior.

Impact of telephone follow-up on COPD outcomes in pulmonary rehabilitation patients: A randomized clinical trial.

Background: The educational component is a comprehensive part of Pulmonary Rehabilitation (PR), and telephone follow-up (TFU) is an alternative to reinforce face-to-face education. The objective was to determine the effect of telephone follow-up on educational needs, dyspnea, quality of life and functional capacity in Chronic Obstructive Pulmonary Disease (COPD) patients undergoing PR. Methods: Double-blind randomized controlled clinical trial in patients with COPD in a PR program in Cali-Colombia, allocation by randomization tables. All patients received 24 sessions of PR, which included face-to-face education sessions. In addition, the experimental group received telephone calls twice a week to reinforce the face-to-face educational content. The Lung Information Needs Questionnaire (LINQ) was used to measure disease knowledge, the Saint George's Respiratory Questionnaire to measure quality of life, the modified Medical Research Council (mMRC) scale to measure dyspnea, and the 6-minute walking test (6MWT) to measure functional capacity. Results: Thirty-four patients were randomized and 31 were analyzed. PR group with conventional education (PRTE) n=15 and PR group with education plus telephone follow-up (PRTETFU) n=16. Significant improvement from baseline to endpoint in both groups: LINQ (PRTE 4±1.1, p=0.003, PRTETFU 5.8±10.6, p=0.000), mMRC (PRTE 1.6±0.3, p=0.000, PRTETFU 0.6±0.3, p=0.036) and functional capacity (PM6M: PRTE 45.9m±16.1, p=0.013, PRTETFU 62.8m±21.4, p=0.010). Analysis showed differences between groups for changes in LINQ knowledge domain after intervention, with greater improvement for PRTETFU (p=0.018). Discussion: The TFU is an alternative to reinforce the education. This study demonstrated greater positive effects for the autonomous management of the pathology. Conclusion: Adding educational reinforcement through phone calls to patients with COPD during PR leads to improved knowledge and skills for managing the disease.

Mhealth tools for community-based infectious disease surveillance in Africa: a scoping review protocol.

INTRODUCTION: Countries in the WHO's African region have found community-based surveillance useful in ensuring the effectiveness of the Integrated Disease Surveillance and Response strategy. This approach encourages community participation in the surveillance system, in addition to early detection of outbreaks and other health threats. Thus, advancements in mobile health have the potential to improve community-based surveillance in Africa. The purpose of this review is to map evidence on available mhealth tools for community-based infectious disease surveillance in Africa. METHODS AND ANALYSIS: The scoping review will follow a mixed-methods approach in line with the framework of Arksey and O'Malley amended by Levac and colleagues and the Joanna Briggs Institute. To retrieve published literature, PubMed, Scopus, Web of Science, Google Scholar and Google databases will be explored. Websites of organisations involved in surveillance activities across the African region will also be explored. Authors will be interested in published literature between 2000 and 2022 in any language. The primary investigator and a second author will independently review the retrieved titles according to the inclusion criteria, while a third reviewer will resolve conflicts that may arise. The review will map evidence according to the key concepts (mhealth, community-based surveillance and Africa) to inform stakeholders and mhealth designers on best practices to adopt involving mhealth approaches at the community level and mhealth tool designs, respectively. Results following the review will be presented according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses: Extension for Scoping Review Guidelines. ETHICS AND DISSEMINATION: Ethical approval is not required for scoping reviews as it does not involve the use of human subjects. This review is the first phase in an overall project on digital health. The findings of the review will be published in a peer-reviewed journal and disseminated at suitable forums and conferences.

Comparison of the Effects of Rosmarinic Acid and Electromagnetic Radiation-Induced Cardiotoxicity on Rats.

Background: Electromagnetic radiation (EMR) causes stable aggregation of reactive oxygen species (ROS), producing oxidative stress. Rosmarinic acid (RA), a plant-origin antioxidant, has been proposed against the side effects of cell phone and ultrahigh-frequency waves. Methods: Forty-two male Wistar rats were randomly divided into 6 groups. Group 1 (controls) received 5 mL of normal saline with the gavage method, Group 2 received 915 MHz radiation, Group 3 received 2450 MHz radiation, Group 4 received RA plus 915 MHz radiation, Group 5 received RA plus 2450MHz radiation, and Group 6 received oral RA (5 mg/kg). Treatment and radiation (1 hour per day) continued for up to 30 days. Results: EMR significantly reduced the activities of superoxide dismutase (SOD), catalase (CAT), and glutathione peroxidase (GPx), the content of glutathione (GSH), and the level of total antioxidant capacity (TAC) and significantly increased oxidative stress indices, such as the levels of malondialdehyde (MDA) and nitric oxide (NO), and the content of protein carbonyl (PC). In contrast, RA significantly elevated TAC level (all groups), GSH content (the RA/cell phone radiation group), GPx activity (the RA/ultrahigh-frequency radiation group), SOD activity (all groups), and CAT activity (RA/ultrahigh-frequency radiation group) and conversely reduced MDA level (all groups), NO level (all groups), and PC content (all groups) in the RA/cell phone and RA/ultrahigh-frequency radiation groups compared with the NS/cell phone and NS/ultrahigh-frequency radiation groups, respectively. The administration of RA resulted in a significant reversal of cardiac markers in EMR-intoxicated rats. Conclusion: RA treatment showed a significant protective effect against EMR-induced cardiotoxicity.

Effects of prenatal mobile phone radiation exposure on MMP9 expression: Implications for inflammation, oxidative stress, and sensory-motor impairment after neonatal hypoxia- ischemia in rats.

Objective: Non-ionizing radiofrequency radiation, which finds application in various sectors such as industry, commerce, medicine, and particularly in mobile phone technology, has emerged as a topic of significant concern during pregnancy. The aim of this study was to investigate the effect of cell phone radio-frequency (RF) radiation during pregnancy on the Matrix metalloproteinase 2 (MMP-2) and (MMP-9) 9 expressions after neonatal hypoxia-ischemia (HI) in rats. Materials and methods: Two groups were formed by randomly assigning female Wistar rats: Group 1 consisted of female rats that were not exposed to RF radiation during pregnancy, while Group 2 comprised female rats that were exposed to RF radiation during pregnancy. After delivery, male offspring were divided into four groups including: (a) SHAM, (b) Exposure (EXP), (c) hypoxia-ischemia (HI), (d) HI/Exposure (HI/EXP). Seven days after HI induction, neurobehavioral tests were performed, and then brain tissue was taken from the skull to measure MMP-2 and MMP-9 expressions, inflammation, oxidative stress, infarct volume and cerebral edema. Results: MMP-9 mRNA expression in the HI/EXP group was significantly higher than the HI, SHAM and EXP groups. MMP-2 mRNA expression levels in the HI group were significantly higher than Sham and the EXP groups.TNF-α and Total oxidant capacity (TOC) levels in the HI/EXP group were significantly higher than HI, EXP and SHAM groups. Total antioxidant capacity (TAC) level in the HI/EXP group were significantly lower than HI, EXP and SHAM groups. Cerebral edema and infarct volume in the HI/EXP group were significantly greater than the HI group. Sensory-motor function was significantly weaker in HI/EXP as compared HI group. Conclusion: Our findings indicate that during pregnancy, exposure to mobile phone RF radiation intensifies damage from HI in rat pups by elevating MMP-9 activity.

Altered gait parameters in distracted walking: a bio-evolutionary and prognostic health perspective on passive listening and active responding during cell phone use.

The underpinnings of bipedal gait are reviewed from an evolutionary biology and prognostic health perspective to better understand issues and concerns related to cell phone use during ambulation and under conditions of distraction and interference. We also consider gait-related health issues associated with the fear of or risk of falling and include prognostic dimensions associated with cognitive decline, dementia, and mortality. Data were acquired on 21 healthy young adults without hearing loss, vestibular, balance, otological or neurological dysfunction using a computerized walkway (GAITRite® Walkway System) combined with specialized software algorithms to extract gait parameters. Four experimental conditions and seven temporo-spatial gait parameters were studied: gait velocity, cadence, stride length, ambulatory time, single-support time, double-support time, and step count. Significant main effects were observed for ambulation time, velocity, stride velocity, and double-support time. The greatest impact of distraction and interference occurred during the texting condition, although other significant effects occurred when participants were verbally responding to queries and passively listening to a story. These experimental observations show that relatively simple distraction and interference tasks implemented through the auditory sensory modality can induce significant perturbations in gait while individuals were ambulating and using a cell phone. Herein, emphasis is placed on the use of quantifiable gait parameters in medical, psychological, and audiological examinations to serve as a foundation for identifying and potentially averting gait-related disturbances.

Analysing olive ripening with digital image RGB histograms.

Digital images are commonly used to monitor processes that are based on colour changes due to their simplicity and easy capture. Colour information in these images can be analysed objectively and accurately using colour histograms. One such process is olive ripening, which is characterized by changes in chemical composition, sensory properties and can be followed by changes in physical appearance, mainly colour. The reference method to quantify the ripeness of olives is the Maturity Index (MI), which is determined by trained experts assigning individual olives into a colour scale through visual inspection. Instead, this study proposes a methodology based on Chemometrics Assisted Colour Histogram-based Analytical Systems (CACHAS) to automatically assess the MI of olives based on R, G, and B colour histograms derived from digital images. The methodology was shown to be easily transferable for routine analysis and capable of controlling the ripening of olives. The study also confirms the high potential of digital images to understand the ripening process of olives (and potentially other fruits) and to predict the MI with satisfactory accuracy, providing an objective and reproducible alternative to visual inspection of trained experts.

Effects of cell phone presence on the control of visual attention during the Navon task.

BACKGROUND: Although cell phones can provide great convenience to our lives, research has shown that they can also affect our behavior, even when not in use. It seems that having a cell phone nearby may not be ideal when the user needs to concentrate on work. However, little is known about whether cell phone presence specifically impairs attentional control. METHODS: This study investigated whether cell phone presence can influence attentional control in the Navon task, which involves spatial switching of attention between global and local levels. RESULTS: It was found that the reaction time for all types of trials decreased when the participants had a cell phone nearby compared to when they had a mobile battery nearby. It was also found that phone dependency led to more incorrect responses among participants, but this effect was independent of the influence of phone presence on the Navon task performance. CONCLUSIONS: These findings indicate that cell phone presence may have a positive influence on the perceptual process of the Navon letter, suggesting that the effects of phone presence are not always negative. One implication provided by this study is that it is possible to challenge the assertion that cell phones should always be excluded from the workplace by highlighting the positive effects of their presence.

Sedentary behavior and neck pain in adults: A systematic review and meta-analysis.

Sedentary lifestyle is an imperative risk for musculoskeletal pain. We sought to investigate the association between different types of sedentary behaviors (SBs) and neck pain (NP) among adults. A systematic search was conducted in PubMed, Web of Science, Embase, Scopus, and Google Scholar up to the end of April 2023. The odds ratio (95% CI) was considered as the desired effect size for the association between SBs and the NP. Among 1881 records found by primary search, 46, and 27 reports were included in the qualitative and quantitative analysis respectively. All included studies qualified as good or fair. Our results indicated that SB is a risk factor for NP among adults (OR = 1.5, [1.29, 1.76]). Computer and mobile phone use were also found to be considerable risk factors for NP (OR = 1.3, [1.12, 1.53], and OR = 2.11, [1.32, 3.42] respectively). However, sitting time showed an insignificant association with NP (OR = 1.33, [0.86, 2.07]). Subgroup analysis revealed that SBs are a significant risk factor for NP among university students (OR = 1.58, [1.27, 1.97]), but the association among office workers was marginally insignificant (OR = 1.36, [0.98, 1.89]). According to the meta-regression results, the male gender was found to increase the risk of NP. Meanwhile, Egger's test revealed the presence of publication bias (p-value <0.0001). A sedentary lifestyle as well as computer and mobile phone use is associated with a considerable risk of NP among adults, especially university students. Further, longitudinal studies are needed to better clarify the causality relationships.

Risky driving behaviors and employer motor vehicle safety policies among U.S. oil and gas extraction workers.

INTRODUCTION: Over half of fatal occupational injuries in the oil and gas extraction (OGE) industry are due to transportation incidents. While driving for work is common in this industry and risky driving behaviors have been identified as contributing factors to fatal crashes among OGE workers, limited information is available on the frequency of risky driving behaviors and employer policies to reduce these behaviors. METHODS: Researchers conducted a cross-sectional survey of OGE workers in three states. Responses from 363 OGE workers who drive as a part of their work duties were analyzed to evaluate relationships between self-reported risky driving behaviors (i.e., speeding, cell phone use, and driving unbelted) and awareness of motor vehicle safety policies by their employers. RESULTS: Hands-free cell phone use was the most common risky driving behavior among participants (59.8%), while a hands-free cell phone ban was the least commonly reported employer motor vehicle safety policy (34.7%). Multiple logistic regression results identified longer work and commuting hours, lack of employer motor vehicle safety policies, having ever been in a work crash, and being employed by an operator to be significantly associated with risky driving behaviors. CONCLUSIONS: Workers whose employers lacked motor vehicle safety policies were more likely to engage in risky driving behaviors. PRACTICAL APPLICATIONS: Results of this survey support the implementation of motor vehicle safety interventions such as bans on texting and handheld and hands-free cell phone use, speed management, and in-vehicle monitoring systems by OGE employers as well as research focusing on the effectiveness of these interventions in OGE. Additional research could examine worker driving behaviors through self-reported data in combination with objective measures.
