The Paradoxical Effect of Repeated Body Checking on Subjective Uncertainty.

Body checking is considered a behavioral expression of the core psychopathology of eating disorders (EDs), namely, overvaluation of body weight and shape. Compulsive checking is motivated by a desire to increase a sense of certainty regarding feared outcomes. Paradoxically, studies showed that repeated checking acts to reduce certainty, forming a vicious cycle. No previous study examined whether the same principle applies for body checking. This study filled this gap by examining the causal effect of repeated body checking on memory certainty regarding checked body parts. In a laboratory-based study, 77 female participants without an ED checked the size and shape of six body parts. Their objective memory regarding which body part was last checked, and subjective certainty about this memory were assessed. Then, one group of participants continued to engage in repeated body checking, and another group repeatedly checked a neutral object. Finally, all participants completed the six body parts checking procedure again, and their objective memory and memory certainty were re-assessed. In both checking groups, objective memory regarding the last body part checked was unaffected by the type of checking performed. Importantly, certainty about memory dropped considerably only among those in the repeated body-checking group. The findings provide the first empirical evidence of a paradoxical effect demonstrating that repeated body checking reduces certainty about checked body parts. The study implies that repeated body checking reduces the quality of information obtained through checking and, as such, could potentially motivate further checking.

X-RAY-GUIDED ENDOVASCULAR SURGERY FOR SUBCLAVIAN STEAL SYNDROME (CLINICAL CASE)

Defining the sequence and methods of revascularization in patients with multifocal atherosclerosis should be associated with a minimal risk of adverse events and identification of predictors of adverse outcomes of operations, which is of great importance for improving the results of surgical treatment. We present a clinical case of successful treatment of a patient with multifocal atherosclerosis. The case included atherosclerotic disease of the left subclavian artery with complete steal syndrome of the brachiocephalic arteries, arteries of the lower limbs and arteries of the heart. It is shown that, when choosing a method for treating multifocal atherosclerosis, treatment should begin with preserving and restoring blood supply to the brain, and followed by restoring blood supply to other body parts.

Improving Outdoor Thermal Comfort for Agricultural Workers: A Study of Heat Stress Relief Measures Using Sun Protection Lotions

The entire study was carried out on a group of 100 female farm workers at the CTAE university campus in Udaipur during the wheat crop harvesting season, with the aim of examining the effectiveness of various heat stress relief measures (sun protection lotion with different sun protection factors, SPF) in improving outdoor thermal comfort. The experiments were designed to assess the average skin temperature of Indian female farm workers under five fixed Wet Bulb Globe Temperature (WBGT) conditions (28, 29, 30, 31, 32°C), all falling within the heat stress category as per American Conference of Governmental Industrial Hygienists (ACGIH) standards. The mean skin temperature was determined using the Hardy du-bois 7-point model formula, which involved measuring the mean temperature of specific body parts of the 100 female farm workers. A variation of ± 0.5°C was considered due to the challenge of achieving precise thermal conditions in open field settings. The experiment aimed to evaluate the thermal and physiological responses of the participants. The findings revealed that the use of sun protection lotion alone resulted in increased cooling effect, thereby expanding the thermal comfort range. Additionally, the application of sun protection lotion alone reduced the mean skin temperature by 0.39, 0.38, 0.36, 0.30, 0.27°C by the end of the work period.

Prevalence and Parasitological Examination of Fish Parasites in Clarias gariefinus from Selected Fish Farms in Sokoto Metropolis, Nigeria

Study’s Excerpt The prevalence of fish parasites in fish farms within the Sokoto metropolis is assessed. The results revealed high prevalence of Camallanus spp. and Capillaria spp. among fish populations. Water quality analysis revealed that there is interaction between physicochemical parameters and parasite prevalence. A comprehensive approach to fish farm management and disease control is provided. Full Abstract Fish are known to be affected by parasites both internally and externally with detrimental effects on fish growth and development. This study aimed to determine the prevalence of fish parasites in selected fish farms in the Sokoto metropolis. A total of one hundred and twenty fish samples were collected from ten selected fish farms and subjected to microscopic examination. Water samples were collected from ten fish farms and analysed using the standard procedures recommended by the American Public Health Association. The results indicate that 35.0% of the fish were infected with the parasite (P<0.0300). Significant high prevalence of 50.0% and 48.1% was recorded in the gender and age groups of the fishes (P<0.0308) and (P=0.0003), respectively. However, a significantly high prevalence of 47.6%, 49.1% and 31.7% was also observed in the length, weight, and body part of the fishes (P<0.0.0000). This study identified two nematode species (Camallanus spp. and Capellaria spp.) with Camallanus spp. showing a higher prevalence of 60.3% was obtained in Camellanus spp. among the parasite species identified. The parameters such as pH, dissolved oxygen (DO) and nitrate (NO3) were assessed, and results were analysed using one-way analysis of variance (ANOVA) with the aid of SPSS version 27.0. The values of the physicochemical parameters were between the range of 6.68+0.11 to 7.83±0.05 for pH, 5.23+0.03 to 8.17±0.88 mg/L for DO, and 13.70+1.37 to 100.33+0.33 for NO3 respectively. All parameters examined were within acceptable limits recommended by the World Health Organization. Maintaining an optimum feeding strategy, regular monitoring of the water quality parameters and vaccinations will help to further decrease the rate of the parasite.

Trends in Upper Extremity Saw Injuries From 2003 to 2022.

Saws are a common source of upper extremity injury. There have been several commercial and government-mandated safety mechanisms designed to reduce the number of saw injuries. We aim to assess the trends in the incidence and impact of saw-related upper extremity injuries over the last 2 decades. The National Electronic Injury Surveillance System database was queried from January 2003 to December 2022 for upper extremity injuries caused by saws. Summary statistics for primary body part injured and diagnosis were calculated. Linear regression was performed to evaluate trends in the number of injuries over time. An estimated 1.38 million injuries (weighted) presenting to emergency departments were reported from January 2003 to December 2022. Patients had a mean age of 50.5 ± 18.1. Digits (82.2%) accounted for most injuries, followed by hands (11.9%). The lower arm (3.4%), wrist (1.66%), shoulder (0.3%), elbow (0.2%), and upper arm (0.2%) accounted for fewer injuries. There was a downtrend in number of saw injuries over the study period (R = 0.83, R2 = 0.69, p < .001). Subgroup analysis showed decreases in number of injuries to fingers (R = -0.82, R2 = 0.67, p < .001) and wrists (R = -0.61, R2 = 0.37, p = .004). The most common diagnoses were lacerations (69.7%), fractures (12.6%), and amputations (9.9%). Upper extremity saw injuries have significantly decreased over the last 20 years. The fingers and hands account for the vast majority of saw injuries, resulting most commonly in lacerations, fractures, and amputations. IV.

Prevalence and treatment of chronic musculoskeletal pain focused on service gaps: a comparative analysis by age group and body part.

Occupational health, grounded in occupational medicine, aims to enhance the well-being and labor productivity of the working population. Within this realm, there has been growing concern over the increasing instances of labor loss due to diminished physical capacity and the rise in musculoskeletal disorders. Chronic pain is also associated with musculoskeletal disorders. Another pressing issue related to chronic musculoskeletal pain was needed assistance services are underutilized, is referred to as a "service gap". Understanding trends based on age and affected regions of the body is indispensable for developing strategies to address chronic musculoskeletal pain in workers. This study aimed to elucidate age-specific trends in the prevalence and number of pain sites in chronic musculoskeletal pain as well as the patterns of treatment during chronic musculoskeletal pain, categorized by age and affected site. This study was conducted in December 2022 in contract to Cross Marketing Inc. The survey began on December 12, 2022 and ended on December 15, 2022. An online survey was administered to 1,946 participants (973 women and 973 men), and responses were collected, ensuring a roughly equal distribution of samples among men and women across six age groups ranging from their 20 to 70 s. The survey inquired about the presence of chronic pain in each of the eight body parts and the adoption of five different treatments when experiencing pain. Statistical analysis was performed using the chi-square test, with the measurement data categorized by age group and body part. The results indicated a significantly higher prevalence of chronic pain at three or more sites among individuals in their 30 s: the prevalence of pain at each of the eight body sites varied with age. Approximately half of the participants did not engage in specific treatments during episodes of chronic pain. The presence or absence of treatment showed no significant differences according to affected site or age group. This study revealed age- and body part-related relationships with chronic musculoskeletal pain in middle-aged patients and highlighted healthcare service gaps in its management in Japan.

THE EFFECT OF A MODIFIED TENODESIS WRIST-HAND ORTHOSIS ON HAND FUNCTION IN PATIENTS WITH TETRAPLEGIA

BACKGROUND: An individual experiencing tetraplegia faces functional limitations due to impaired hand function. The use of an affordable tenodesis wrist-hand orthosis (WHO) can enable finger flexion with active wrist extension, thereby enhancing the three-jaw chuck grasp and overall hand functionality. OBJECTIVES: To assess hand function and satisfaction in patients with tetraplegia using a modified tenodesis wrist-hand orthosis (WHO), utilizing the Duruöz Hand Index (DHI) and the Orthotics and Prosthetics User Survey (OPUS) satisfaction with device and services subscales. METHODOLOGY: The study was conducted at a tertiary care center in central India, enrolling patients with tetraplegia admitted to the Department of Physical Medicine and Rehabilitation. A modified tenodesis wrist-hand orthosis (WHO) was designed using low-temperature thermoplastic components. Twenty-two individuals with a minimum wrist extensor power of grade 3/5 were included in the study. These patients were provided with the modified tenodesis WHO and underwent daily training sessions for a period of 2 weeks. Duruöz Hand Index (DHI) scores were assessed at baseline, 6 weeks, and 12 weeks post-enrolment. Patient satisfaction was evaluated using the Orthotics and Prosthetics User’s Survey (OPUS) satisfaction with device and services subscales. FINDINGS: The analysis of the DHI scores indicated a significant enhancement in functional abilities at both 6-week and 12-week follow-ups compared to the baseline assessment. Notably, the most substantial progress at 6 weeks follow-up was observed in tasks such as buttoning a shirt, while significant improvement at the 12-week mark was noted in activities like turning a key in a lock. The median OPUS device satisfaction score was 50, corresponding to a Rasch score of 68.8. Additionally, the median OPUS satisfaction score for services stood at 46, with a Rasch score of 72.7. Patients expressed the highest satisfaction levels with the courteous demeanor of the staff, prompt scheduling of appointments, and accurate fitting of the orthosis. CONCLUSION: The study findings indicate that the modified tenodesis WHO is an effective and satisfactory therapeutic device for improving hand function in patients with tetraplegia. The findings encourage further investigation and application of the modified tenodesis WHO in clinical practice. Layman's Abstract Individuals who are affected due to spinal cord injury (SCI) are often unable to perform the basic daily activities of life due to weakness. The hands are one of the most specialized parts of the human body and loss of its function can be incapacitating. Certain wrist hand orthoses (WHO) can aid such individuals by assisting the weak hand muscles. One such WHO is a tenodesis wrist hand orthosis. Modifications to the previously available tenodesis wrist hand orthosis were made to make it cheaper, lighter, and easier to manufacture. The effectiveness of this modified tenodesis WHO on improving hand activity and satisfaction in the individuals using it was assessed in this study which was conducted in a tertiary care center in central India. Twenty-two individuals with cervical SCI, who had some ability to extend their wrists against gravity, were admitted to the Physical Medicine and Rehabilitation department and enrolled in this study. Notable improvements were observed in functional tasks such as buttoning a shirt, opening a lock, eating with a fork, brushing teeth, and writing, with considerable satisfaction in those trained with the modified tenodesis WHO.

Self-puberty staging in endocrine encounters during the COVID pandemic

BackgroundEvaluation of pubertal development is crucial in Endocrinology. The rise in telemedicine during COVID-19 has made conduct of physical examinations more challenging, especially for pubertal assessment. Previous studies on validity of pubertal self-staging versus clinical examination have yielded mixed results. This study aimed to determine validity and reliability of self-staging of puberty, with potential application during telemedicine visits. The present study is the first to assess pediatric self-rated pubertal staging during the pandemic.MethodsThe study included patients aged 7-22 years referred to Pediatric Endocrinology for specialty care, including pubertal staging. At clinic check-in, patients received a packet with study description, an option to “opt in” or “opt out”, sex-specific self-staging instructions, and Tanner (T) stage illustrations. Males received materials for pubic hair (PH) stages T1-T5; females received materials for PH and breast (BR) stages T1-T5. Patients who opted in had 10 minutes to select the image(s) that best matched their bodies, which they sealed in an envelope. This was followed by a clinic visit, where a board-certified pediatric endocrinologist conducted a physical examination, including breast staging (females), testicular size measurement (males), and pubic hair staging (both sexes). Pubertal stage Kappa statistics with 95% CI were calculated for each body part by sex, with Kappa ≥ 0.60 indicating significant agreement between self-assessment and physician assessment (0.40-0.60 moderate; 0.20-0.40 fair).ResultsOf 516 distributed packets, 243 self-assessments (125 females) were returned, with 81% (94 females/102 males) being complete (including pediatric endocrinologist staging). Mean age of participants was 12.8 years. Mean BMI was 22.2 kg/m² (males) and 23.7 kg/m² (females). Hypothyroidism was the most common endocrine diagnosis. For females, kappa was highest for BR and PH in T1 (BR 0.65, PH 0.57) and T5 (BR 0.57, PH 0.65). For males, kappa was highest in T1 (0.73) and T2 (0.58). Grouping Tanner stages into prepuberty (T1), early to mid-puberty (T2-T3), and late puberty (T4-T5) showed greater agreement.ConclusionPatients can reliably distinguish between “puberty” and “no puberty” using self-staging, though differentiating between later pubertal stages is more challenging. These findings help define the utility and limitations of self-staging during telemedicine visits.

Role of inflammation and macrophages in the formation of the atrial cardiomyopathy associated with obesity

Abstract Introduction The atrial fibrillation (AF), the most frequent cardiac arrhythmia in clinical practice is often associated with an atrial cardiomyopathy (ACM) which is favoured by several clinical conditions including metabolic diseases such as obesity. Recently, the epicardial adipose tissue (EAT) has emerged as an important component of ACM notably in the context of metabolic diseases. Epicardial progenitor cells (EPC) are the main source of EAT. The replacement of EAT by fibrosis is arrhythmogenic and involved inflammation but not yet characterized. The hypothesis tested here is that macrophages are central players for both the recruitment of EPC and replacement of EAT by fibrosis. Purpose-Aims First to characterize subpopulation of macrophages involves in the progression of ACM. Second, to study how the inflammatory environment regulates EPC differentiation. Method A spatial gene expression was used to analyze human samples (n=4) (Agreement, CODECOH, Declaration or authorization of activities involving the preservation and preparation of human body parts for scientific purposes DC-2020-4183). A well-characterized mouse model of atrial cardiomyopathy associated with obesity induced by high fat diet (HFD) was used to characterize macrophages associated with progression of ACM by using immunolabeling together with single nuclei RNA sequencing approaches. ACM was characterized by using echocardiography and atrial burst pacing to evaluate determine AF vulnerability. Transgenic RGB-MAC mice with macrophages tagged with McApple-Csf1R and ECGFP-CX3CR1 or with a knock-out for CCR2 were used to follow infiltration of myeloid cells in the atrial at the different stages of the ACM. Bi-photon microscopy was used to visualize cell subpopulations in the distinct area of the atrial wall. In some experiments EPC and macrophages were cocultured with transwell. Results Macrophages were detected in subepicardium of human atrial samples in area of fibro-fatty infiltrates. After 2 months of HFD, monocytes were infiltrated atria and macrophages were overexpressed in atria from 1 to 4 months of HFD. Using Bi-photon microscopy it was possible to visualise resident ECGFP-CX3CR1+ macrophages at the contact of EAT whereas McApple-Csfr1r+ macrophages were at the junction with fibrosis (figure 1). Preliminary data generated by single nuclei RNA sequencing showed clusters of different subpopulations of macrophages at different time point of the ACM (figure 2). We will present results on the effects of suppression of the CCR2 subpopulation of macrophages on characteristics of the ACM. Conclusion Distinct populations of macrophages i.e resident and monocyte-derived macrophages, participate to the distinct stages of the ACM caused by obesity in mice.Myeloid cells infiltration in epicardiumCCR2+cells infiltration in EAT-fibrosis

Insights from a hospital database: injuries among children under 6 years old due to falls

Abstract Background Pediatric injuries represent a significant public health concern globally, contributing to substantial morbidity and mortality among children. In Georgia, limited data exists regarding pediatric injuries. The aim of the study was to analyze epidemiological characteristics and trends of pediatric injuries among children aged under 6 years who received treatment in hospitals across whole country. Methods NCDC hospitalization database for 2015-2022 was used for the study. Results Over the study period, a total of 5979 children under the age of 6 received treatment in all hospitals across Georgia. The highest number of hospital admissions were registered in 2019. 60% were boys and 40% were girls of the hospitalized patients. Boys were predominant across all age groups, with the highest proportion among children aged 5 years old. There was a significant variation in hospital admissions according to the seasons, with the highest admissions occurrence in summer. As for the cause of admission, 37% resulted from falls on the same level, 10% from falls between different levels, 7% involved falling from a bed, 4% from falling out or through a building, and 4% from falling down stairs. The cause of falls was unspecified in 23%. In 72% of cases, the injured body part was the head, 17% were upper extremity injuries, and 7% were lower extremity injuries. Of the patients, 90% recovered, 2% discontinued treatment, 8% were transferred, and the outcome was fatal for 0.23% of patients. Among the fatal cases, 36% resulted from falls from, out of, or through a building, 29% from falls between different levels, 14% from falling or jumping, 7% from falls involving a bed, and 7% from falls on the same level. Conclusions These findings underscore the importance of preventive measures, especially regarding fall prevention, to reduce the incidence of pediatric injuries in Georgia. Key messages • There was a significant variation in hospital admissions according to the seasons, with the highest admissions occurrence in summer. • These findings underscore the importance of preventive measures, especially regarding fall prevention, to reduce the incidence of pediatric injuries in Georgia.

Improving family engagement during implementation of IEP-aided AAC services: an interdisciplinary US-based perspective

All IEP team members should find statements pointing to where and when the aided AAC system and accessible learning tools will be used. Classroom-based and research supported AAC learning strategies and teaching practices should be clearly listed, explained, and accessible to all team members. Aided AAC refers to a variety of communication tools that are portable and external to the body. Aided AAC ranges from paper-based picture communication cards, boards, binders, tablets, or digital smartphone applications to multifunctional/high-tech devices offering synthesized and digitized speech. Aided AAC allows students with CCN/ESNs to access speech or writing using any body part capable of performing voluntary and independent movement. Many electronic/high-tech aided AAC systems can store thousands of multilingual words, allowing seamless communication between home and school. Students with CCN/ESNs can also use hightech aided AAC with native keyboards as “alternative pencils” to practice spelling and early writing, thus allowing equitable academic access and opportunities to make progress on emergent literacy skills. High-tech/digital-aided AAC allows for the maturation of linguistic specificity and fuller participation in daily routines required for academic success. It is critical for students with CCN/ESNs to use high-tech aided AAC with ample vocabulary storage to increase opportunities for self-generation of complex and decontextualized messages for varied social interactions. Additionally, digital device platforms (e.g., iPads, other tablets, Smartphones) offer multiple.

The Physiological Effect Of Zinc Oxide (ZnO) Nanopesticide On Aedes aegypti Larvae

Aedes aegypti is responsible for transmitting various mosquito-borne diseases. Recently, there have been concerns about the negative impacts of the insecticides used in vector control including insecticide resistance development in the mosquito population. These circumstances lead to efforts to develop other strategies for controlling mosquito vectors. As technology in nanoparticles advances, zinc oxide (ZnO) nanoparticles have the potential as the alternative for chemical pesticides for mosquito larvicides due to their optical properties and widespread usage in different industries. The purpose of this study was to determine the toxicity of ZnO nanoparticles towards Ae. aegypti larvae and to examine the physiologies of Ae. aegypti mosquito larvae treated with ZnO nanoparticles at LC50 level. Toxicity bioassays were carried out to determine LC50 and LC90 values. The larvae surface and midgut treated with LC50 ZnO were examined using the Scanning Electron Microscope (FESEM) and Dispersive X-ray spectroscopy (EDX). The LC50 and LC90 concentrations of ZnO nanoparticles after 4 hr of direct UV exposure against Ae. aegypti larvae were 49.141 mg/L and 64.195 mg/L, respectively. After exposure to ZnO nanoparticles, Ae. aegypti larvae showed morphological abnormalities, including distorted and shrunk body parts as well as midgut rupture. Overall, the findings suggest that ZnO nanoparticles have the potential to replace chemical pesticides as a means of reducing the populations of Ae. aegypti mosquitoes.

Effectiveness of high-intensity laser therapy on pain in tendinopathy

Introduction: High-intensity laser therapies (HILT) have gained significant attention in therapeutic pain treat-ment. The aim of this systematic review was to determine the effectiveness of HILT therapies in the management of different types of tendinopathy-related pain, and the long-term benefits associated with treatment process.Methodology: A systematic literature review of prospective randomized controlled trials from electronic data-bases: Google Scholar, Pub Med, Embase, Science Direct, and ProQuest, using relevant key words, was per-formed. Randomized trials that included HILT, patients with tendinopathy, pain management, and at least one single clinically pertinent attribute were selected. Standard PRISMA protocols were followed when completing the assessment.Results: The physical, demographic, and theoretical insights from various studies suggest that HILT is a highly promising approach for managing pain in patients with tendinopathy. The most common body parts for treating tendinopathy using this method were the shoulder, elbow, ankle, and knee. Various attributes and parameters, such as Hand function evaluated by Quick Disabilities of Arm, Shoulder and Hand Questionnaire (QDASH) and Hand-grip Strength; pain assessed by the visual analogue score (VAS) during rest or activity, 36-item short-form health survey (SF-36) for physical and mental health, and the shoulder pain and Disability Index (SPADI) for shoulder and elbow assessment, were frequently significant across studies.Conclusion: HILT could be recommended as a treatment of choice for reducing pain and improving function in patients with tendinopathy, with potential benefits when combined with other physical therapy treatments. Further studies are needed to clarify optimal treatment protocols and long- term outcomes.

Ayurvedic Insights into Yakrit Vikara: A Comprehensive Study on Differential Diagnosis

In Ayurveda, the concept of Koshtanga highlights the intricate interconnectedness of various body parts, with the Yakrit(liver) identified as a vital organ that plays a crucial role in the functioning of the raktavahsrotas (blood channels). The relationship between Rakta (blood) and Yakritis essential for sustaining overall health and well-being. A definitive diagnosis is paramount for providing appropriate treatment for any disease. By examining the different stages of illness and the consequential changes that occur, practitioners can achieve a more accurate diagnosis. Ayurvedic texts typically do not classify liver disorders (Yakrita Vikara) as independent entities, largely because the system's classification of diseases is predominantly based on symptoms. This paper delves into various liver-related disorders, such as Pandu, both types of Kamala, Shakhashrita, and Kosthashrita. It also discusses the different stages of Kamalaand Madya Janya Yakrita Vikara, highlighting the importance of understanding the symptoms that overlap across these conditions to aid in differential diagnosis. Furthermore, there is a pressing need for a more thorough examination of liver disorders within the framework of this ancient traditional system. By exploring the unique concepts presented in ancient Ayurvedic literature, we can enhance our understanding of liver health and broaden the scope of research into the multidimensional aspects of Yakritvikara, along with its differential diagnosis. This exploration can lead to improved diagnostic accuracy and more effective treatment strategies rooted in traditional wisdom

Age related differences in whole body and body part angular momentum in the frontal plane during walking

The contribution of body part angular momentum (BPAM) to whole body angular momentum (WBAM) in the frontal plane during walking differs across age groups. We investigated age related differences in BPAM and WBAM during walking. We used marker coordinate data from a publicly available database for 54 individuals aged 20–30 years and 78 aged 60–70 years. Angular momentum in the frontal plane was calculated as the sum of the translational component and the rotational component for each segment. The angular momentum of each segment was categorized into five BPAM: right and left lower limbs (foot, shank, and thigh), right and left arms (hand, forearm, and upper arm), and torso (head, thorax, and pelvis). BPAM at WBAM peak frames during stride cycles was compared between older and younger adults. The peak WBAM, angular momentum of the stance-and swing side upper limbs, and torso in older adults was significantly larger than that in younger adults, with increases of 74.6% in the stance-side upper limb, 127.5% in the swing-side upper limb, and 30.9% in the torso. These results suggest that interventions aimed at improving torso control could decrease the amplitude of WBAM in the frontal plane in older adults.

Analisis Postur Kerja Pada Bagian Packing Menggunakan Metode ManTRA Dan REBA

PT. Indonesia Plafon Semesta is a company engaged in manufacturing, this company produces various kinds of PVC ceilings. Problems faced by PT. Indonesia Plafon Semesta is the activity of making PVC ceilings in the packing section, where the activity conditions or workers' posture is not good. When packing by squatting and bending, the position is less ergonomic, resulting in excessive force exertion and the risk of injury.

Waste 4.0: transforming medical waste management through digitalization and automated segregation

Medical waste management is a crucial issue due to its potential health risks to humans and harm to the environment. The World Health Organization (WHO) advises separating medical waste into seven groups based on its type. However, despite the implementation of color-coded bin bags, cases of missegregation still occur frequently, leading to injuries and spreading diseases. Infectious waste such as sharps, human tissue, and body parts are often found mixed in waste bins, posing a severe threat to waste employees. To address this issue, this paper proposes exploring the potential of digitalization in waste segregation. The literature on current segregation methods and technology applications is analysed and compared, and a framework for utilizing barcode tagging and scanning to ensure waste is correctly categorized is presented. The barcodes and scanner will be connected through a monitoring system, which can notify waste generators and collectors of misplacing or mixed waste. This digitalization system is expected to serve as a monitoring agent for segregating waste before it is collected from any health facilities. Additionally, the exchanged data from waste generator bins can inform collectors and other waste stakeholders about the waste's condition, potentially opening up opportunities for recycling companies to purchase used plastics or metals from hospital wastes. By implementing digitalization in medical waste management, waste segregation can improve, reduce the spread of diseases and injuries, and promote the recycling of hospital waste materials.

Customized Preparation of Heat-Resistant Fully Flexible Sensors Based on Coaxial 3D Printing.

The conventional behavior recognition strategy for wearable sensors used in high-temperature environments typically requires an external power supply, and the manufacturing process is cumbersome. Herein, we present a rational design strategy based on fully flexible printable materials and a customized device-manufacturing process for skin-conformable triboelectric nanogenerator sensors. In detail, using high temperature-resistant ink and 3D printing technology to manufacture a coaxial triboelectric nanogenerator (C-TENG) sensor, the C-TENG exhibits high stretchability (>400%), a wide working range (>250 °C), and high output voltage (>100 V). The C-TENG can be worn on various parts of the human body, providing a robust skin-device interface that recognizes diverse human behaviors. Using machine learning algorithms, behaviors such as walking, running, sitting, squatting, climbing stairs, and falling can be identified, achieving 100% behavior recognition accuracy through the selective input and optimization of an appropriate dataset. This paper provides a research perspective for the customization, extension, and rapid fabrication of heat-resistant, fully flexible TENGs.

Accounts of Spine and Paraspinal Disease while Playing Golf

The twisting motion associated with the golf swing puts the intervertebral discs and the paraspinal musculature under stress. The objective of this study was to characterize the spinal and paraspinal pathologies associated with golf and their outcomes. The National Electronic Injury Surveillance System (NEISS) was queried for emergency department visits between 2003-2023 for golf-related injuries with body part codes "neck", "upper trunk", and "lower trunk", which includes the cervical, thoracic, and lumbar spine, respectively. Narratives were screened for relevance and reports related to spinal and paraspinal injuries were included. Weighted survey analysis was utilized to construct national estimates. Injury and diagnosis trends were analyzed using binomial logistic regression, and time trends were analyzed with a linear model. P-value of < 0.05 was considered significant. A total of 1441 relevant samples led to a national estimate of 69,153 emergency department visits for golf-related spinal-/paraspinal injuries between 2003-2023. The weighted mean age of those injured was 52.8 years, and the majority were male (85%, 95% CI 83-87). Strain was the most diagnosed injury (57.5%, 95% CI 54-61). Those aged > 55 years constituted more injuries than any other age group (50.1%, 95% CI 47-53). Injuries in the lumbar region accounted for most cases (76.9%, 95% CI 74-80). Injury frequency did not change over the years (p= 0.54), although the age of injury did increase over time (p < 0.001). Golf-associated paraspinal injuries are more common than neurological injuries, necessitating study into their mechanisms and onset.

From faces to fingers: Examining attentional capture of faces and body parts using colour singleton paradigm.

Faces and body parts play a crucial role in human social communication. Numerous studies emphasize their significance as sociobiological stimuli in daily interactions. Two experiments were conducted to examine the following: (a) whether faces or body parts are processed more quickly than other visual objects when relevant to the task and serving as targets, and (b) the effects of presenting faces or body parts as distractors on task reaction times and error rates. The first experiment focused on either faces or body parts, with five different visual objects. The second experiment examined effector body parts (e.g., hands) and core body parts (e.g., the torso), paired with the same visual objects. Thirty-six participants took part in the study, equally divided between Experiment 1 (N = 18) and Experiment 2 (N = 18). Participants were instructed to find if a target item, indicated by a green placeholder, matched a previously presented word cue, while they were instructed to keep ignoring the singleton object that was surrounded by the red placeholder. The results indicated that participants responded more quickly when finding faces but not body parts in Experiment 1. No such advantage was seen in Experiment 2 for either effector or core body parts compared to other objects. Interestingly, when faces were presented as distractors as a singleton, reaction times increased (Experiment 1), indicating that faces capture attention. This effect was not observed for effector or core body parts (Experiment 2). These findings suggest that faces capture attention more effectively than body parts.
