Vilém Flusser’s chiro-phenomenology fills an essential gap in scholarship by expanding and reinterpreting the ontological significance of gestures, focusing on the hand as a crucial site for understanding the embodied nature of human existence. This article explores Flusser’s unique contribution to the phenomenology of the hand, highlighting why his approach is necessary for a fuller understanding of gesture and embodiment. I begin by emphasizing the relevance of the hand in understanding gestures, arguing that phenomenology provides rich resources for this inquiry. Within the phenomenological tradition, two distinct perspectives emerge: Husserl and Merleau-Ponty, who concentrate on the perceptive and kinesthetic dimensions of the hand, and Heidegger and Levinas, who explore its ontological significance, viewing the hand as essential to human existence. I position Flusser within this ontological framework but show how he departs from his predecessors by developing an original manual approach that centers on the ‘gesture of making.’ By analyzing the eleven constitutive moments of this gesture, I demonstrate how Flusser’s chiro-phenomenology views gestures not only as expressive or communicative acts but as fundamental possibilities for human being-in-the-world. His work thus offers a crucial extension of phenomenology’s understanding of the body and action. [ABSTRACT FROM AUTHOR]

The significance of Elinor and Marianne Dashwood's bond in Jane Austen's Sense and Sensibility has been well acknowledged by critics. In the midst of lackluster suitors, malicious relations, and brazen gossips, Elinor and Marianne's relationship seems the only one that really matters in the end. Yet despite the centrality of Elinor and Marianne's intimacy, the novel concludes with their respective marriages to Edward Ferrars and Colonel Brandon. Turning our attention toward the phenomenology of hands and touch in Sense and Sensibility, however, changes the way we approach narrative by undermining the teleology of the marriage plot. In contrast to the hollow acts and mediating objects of affection offered by potential suitors, Willoughby and Edward Ferrars, Elinor and Marianne's handholding constitutes deeply affective and unmediated moments of physical contact that attest to the primacy of touch underlying the most passionate attachments. In this light, the concluding marriages do not recant the rest of the novel but rather serve a strategic choice motivated by what these marriages make possible. Far from enforcing heterosexual closure, Elinor and Marianne's marriages fulfill a different agenda: preserving the sisters' lasting haptic contact with one another. [ABSTRACT FROM AUTHOR]

AbstractThe term vibration perception threshold (VPT) refers to the minimum amplitude required for a vibration to be consciously perceived. Knowledge of VPTs can be used to aid in the diagnosis of various pathologies, or to support design decisions during human-machine interface development. However, several factors affect VPT measurements (e.g., contactor size and pressure), thus, comparing VPT results from multiple studies should not be done without considering both the similarities and differences between said studies. This paper presents a systematic review on VPT results obtained across multiple studies, taking into consideration the different factors affecting the values reported in the literature. We intended to answer the following question: “What are the Vibration Perception Thresholds assessed on the glabrous skin of the hands and fingers of healthy humans?” To the best of our knowledge, this is the first attempt at conducting a systematic review focused specifically on numerical VPT results. Starting from 936 records, VPT results from 37 studies were organized according to various factors (gender, age, probe size, contact pressure, psychophysical method, room temperature, skin temperature, and hand location). This data was organized into a table, the Organization Table that is available for readers. This review can help future researchers and developers working on or working with the topic of human perception of vibrations by examining the factors that affect VPTs and discussing strategies to address them. We offer recommendations for future research and insights on how design engineers can utilize VPTs in the development of new haptic devices. [ABSTRACT FROM AUTHOR]

Introduction: Cutaneous squamous cell carcinoma (SCC) accounts for 20% of all skin cancers and its incidence continues to increase globally. It represents 75% of non-melanoma skin cancer (NMSC) mortality. Risk factors include ultraviolet radiation (UVR) exposure, advanced age, chemical exposure, fair skin types, and immunosuppression. While most human papillomavirus (HPV) infections are associated with the development of warts, a subgroup is potentially implicated in the development of cutaneous SCC. The prevalence of alpha, beta, and gamma-HPV in Chilean patients with hand SCCs has not been previously addressed. The objective of this study was to evaluate the presence of HPV and genotyping in hand SCC from Chilean patients. Materials and methods: An observational, cross-sectional, descriptive study was conducted. Alpha (α), beta (β) and gamma (γ)-HPV detection was performed by conventional polymerase chain reaction (PCR) in paraffin-embedded tissue samples from 52 patients diagnosed with hand SCC from Santiago, Chile. HPV genotyping was carried out via direct amplicon sequencing by Sanger method. Results: The most frequent carcinoma site was the dorsum of the hands (52.5%). α-HPV was not detected in these specimens, whereas β-HPV and γ-HPV were detected in 25% of the analyzed samples. The most frequent genotypes found were β-HPV 100 (38%) and γ-HPV 178 (15%). Additionally, γ-HPV 101, 162, HPV-mSK_016, HPV-mSK_083, HPV-mSK_213 and HPV-mSK249nr genotypes were detected, none of which had been previously described in cutaneous SCC. Conclusion: β-HPV and γ-HPV are detectable in 25% of hand SCCs from Chilean patients. It is important to conduct prospective studies to better elucidate the role of these viruses in the development of this disease. [ABSTRACT FROM AUTHOR]

In ancient Hebrew, the word for “hand” can also refer metaphorically to personal power—or be innuendo for the phallus. This observation serves as a key to the many appearances of “hands” in the book of Esther, from the king’s superlative “hand” to the ever-active “hands” of eunuchs. This abundance of hands has an ironic significance, alternately humorous and profound, as it points to the non-procreative nature of power in Esther’s Persia. Drawing from Lee Edelman’s theory of reproductive futurism, this article examines the upside-down, queer world of Esther, where the “hands” that matter are precisely those “hands” that society views as disabled.

The English word digital (from the Latin, digitus) etymologically connects both fingers and technologies. In this special issue, we honor this dual meaning of the digital by foregrounding how living in a digital era both challenges and actualizes our senses, particularly our sense of touch. Ethnographically, the articles gathered offer intimate accounts of tactile experiences that intertwine with the digital in both direct and indirect ways. Despite ongoing—and often legitimate—anxieties about the disappearance of touch from our increasingly digitized world, our special issue shows that human engagements with digital technologies are more complex. We theorize touch through a phenomenological and relational lens and as a sensory experience that is deeply shaped and reconfigured by local, sociotechnical and political‐economic concerns. This special issue illuminates how attention to hands, fingers, or touch can help us understand the relationship between bodies, ethical life, social relations, selves, and subjectivities through a new lens.

Objectives: This study aims to conduct a thorough characterization of hand morphology. Employing a 2D geometric morphometric approach, we scrutinize individual fingers and the palm, delineating the ontogenetic trajectories for each biological sex and investigating the alterations that take place at various stages of human development. Materials and methods: A set of thirty‐two 2D anatomical landmarks were assessed in a sex‐balanced sample of human hands (F = 275, M = 250 males), spanning all stages of human development. Following Procrustes registration, the data on size and shape for individual fingers and the palm were examined for each biological sex and age group. Regression analysis was utilized to quantify ontogenetic trajectories for each biological sex. Results: The findings suggest a gradual escalation in sexual dimorphism throughout human development, with statistically noteworthy distinctions becoming apparent in size starting at the age of 3, and in shape from the age of 7 onwards. Additionally, our analyses uncover a distinctive sigmoid pattern between sexes, indicating that biological male hands exhibit a sturdier build compared to biological female hands from early childhood onward. Conclusions: In conclusion, this study enriches our insights into sexual dimorphism in human hands, stressing the importance of considering both size and shape across different ontogenetic stages. These findings not only expand our understanding of human biological variation but also lay the foundation for future interdisciplinary research in diverse scientific domains. [ABSTRACT FROM AUTHOR]

To understand conditions such as body dysmorphic disorder, we need to understand healthy individuals' perceptual, conceptual, and emotional representations of their bodies. Not much is known about the differences in these representations across body districts, for example, hands, feet, and whole-body, despite their differences at sensory and functional levels. To understand this, we developed more implicit and explicit measures of body satisfaction for these body districts. Sixty-seven participants (age M = 30.66, SD = 11.19) completed a series of online Implicit Association Tests (IAT) and a Body Image Satisfaction Visual Analogue Scale (BISVAS; explicit) for each body district (hands/feet/whole body). The results show no differences in the more implicit level of awareness in hands, feet and whole body, while differences are apparent at a more explicit level of awareness, with higher scores for body image satisfaction for the hands than the whole body and marginally significant lower scores for feet than hands. Those findings suggest that visual attention, level of concern attributed to a body district, and disgust drivers are possible factors affecting the experience of attitudinal body image satisfaction.

A filler composed of calcium hydroxylapatite and carboxymethylcellulose gel (CaHA/CMC) has been shown to possess biostimulatory and skin‐tightening properties that have been applied not just to the face but also to the body to boost rejuvenation. Recently, evidence and recommendations for CaHA/CMC treatment of the face have been provided, but they are still lacking in terms of body treatment. This article aims to perform a systematic review of the literature on CaHA/CMC applications on the body and provide evidence from the literature. Currently, the only FDA‐approved indication on the body is treating the hands and a recent European Union Medical Device Regulation approval has been released for decolletage treatment. The application of hyperdilutions on the neck, feet, arms, thighs, abdomen, and other body parts has been proven to provide a skin‐tightening effect. However, despite their wide use with a good safety profile in clinical practice, recent trends and guidelines of diluted and hyperdiluted CaHA/CMC have yet to be supported by randomized controlled trials.

Background: Acral actinic keratosis (AK) lesions are considered difficult to treat, and published data for photodynamic therapy (PDT) on these lesions is limited. Thus, we evaluated sustained efficacy, safety, and satisfaction after PDT for AK on the hands. Methods: We analysed subgroup data for treatment on the hands from a randomised, double-blind, intra-individual phase III study. All participants previously underwent up to two field-directed red light PDTs with 10 % 5-aminolevulinic acid nanoemulsion gel (BF-200 ALA). Assessments included pain during PDT, clearance and recurrence rates, and satisfaction. Results: 24 participants treated on the hands were included; 21 participants were analysed. Complete clearance rates with BF-200 ALA were 90.9 % (lesion-based) and 76.2 % (per participant's side), both markedly higher than with vehicle. The lesion recurrence rate with BF-200 ALA was 29.0 %. Adverse events reflected the mode of action. Mean pain intensities were 4.8 ± 3.8 (BF-200 ALA) and 0.8 ± 2.1 (vehicle) on an 11-point numeric rating scale. Most participants (81.0 %) rated their satisfaction with BF-200 ALA as very good or good. Conclusion: This subgroup analysis indicates that PDT with BF-200 ALA provides a suitable treatment for AK lesions on the hands.

The article discusses the effectiveness of dupilumab in treating atopic dermatitis on the hands, a common and challenging area for treatment due to exposure to various irritants. A study on 485 patients showed that after 3 years of treatment, 85.6% achieved complete remission in the hands. The research highlights the importance of prolonged treatment with dupilumab for patients with atopic dermatitis on the hands, emphasizing the potential for significant improvement in quality of life.

Climate change may impact human health through the influence of weather on environmental transmission of diarrhea. Previous studies have found that high temperatures and heavy precipitation are associated with increased diarrhea prevalence, but the underlying causal mechanisms have not been tested and validated. We linked measurements of Escherichia coli in source water (n = 1673), stored drinking water (n = 9692), and hand rinses from children

Abstract Background Fractures of hands and feet are common in children, but relevant epidemiological studies are currently lacking. We aim to study the epidemiological characteristics of hand and foot fractures and growth plate injuries in children and provide a theoretical basis for their prevention, diagnosis, and treatment. Methods We retrospectively analyzed the data of children with hand and foot fractures who were hospitalized at Shenzhen Children’s Hospital between July 2015 and December 2020. Data on demographic characteristics, fracture site, treatment method, etiology of injury, and accompanying injuries were collected. The children were divided into four age groups: infants, preschool children, school children, and adolescents. The fracture sites were classified as first-level (the first–fifth finger/toe, metacarpal, metatarsal, carpal, and tarsal) and second-level (the first–fifth: proximal phalanx, middle phalanx, distal phalanx, metacarpal, and metatarsal) sites. The changing trends in fracture locations and injury causes among children in each age group were analyzed. Results Overall, 1301 children (1561 fractures; 835 boys and 466 girls) were included. The largest number of fractures occurred in preschool children (n = 549, 42.20%), with the distal phalanx of the third finger being the most common site (n = 73, 15.57%). The number of fractures in adolescents was the lowest (n = 158, 12.14%), and the most common fracture site was the proximal phalanx of the fifth finger (n = 45, 29.61%). Of the 1561 fractures, 1143 occurred in the hands and 418 in the feet. The most and least common first-level fracture sites among hand fractures were the fifth (n = 300, 26.25%) and first (n = 138, 12.07%) fingers, respectively. The most and least common first-level foot fracture locations were the first (n = 83, 19.86%) and fourth (n = 26, 6.22%) toes, respectively. The most common first-level and second level etiologies were life related injuries (n = 1128, 86.70%) and clipping injuries (n = 428, 32.90%), respectively. The incidence of sports injuries gradually increased with age, accounting for the highest proportion in adolescents (26.58%). Hand and foot fractures had many accompanying injuries, with the top three being nail bed injuries (570 cases, 36.52%), growth plate injuries (296 cases, 18.96%), and distal severed fracture (167 cases, 10.70%). Among the 296 growth plate injuries, 246 occurred on the hands and 50 on the feet. Conclusions In contrast to previous epidemiological studies on pediatric hand and foot fractures, we mapped the locations of these fractures, including proximal, shaft, distal, and epiphyseal plate injuries. We analyzed the changing trends in fracture sites and injury etiologies with age. Hand and foot fractures have many accompanying injuries that require attention during diagnosis and treatment. Doctors should formulate accident protection measures for children of different ages, strengthen safety education, and reduce the occurrence of accidental injuries.

Introduction: Fireworks are commonly used to celebrate holidays and events with potential to impact livelihoods from blast injuries. This study aims to describe and analyse firework related burns in adults across Australia and New Zealand (ANZ). Methods: A retrospective review from January 2010 – January 2023 across all ANZ adult burns units. All firework related burn injuries in adults greater than 18 years that attended or were referred to the burns unit were included. Results: There were 173 patients with a firework related burn injury. The male to female ratio was 4.4:1 with the majority representing a younger age group (18–45 years). Men were significantly more likely to have firework related injuries at home and /or outside than women (49.3 % vs 24.2 %, p = 0.009). There were 29 firecrackers, 44 sparklers, and 99 firework burn injuries with significant differences in proportions between states for sparklers and fireworks. The mean TBSA was 4.3 % with significant differences amongst sex (men 4.7 % vs women 2.0 %, p = 0.042) and amongst states. Adequate first aid was reported higher in men than women (61.4 % vs 42.4 %, p = 0.047). Approximately half the injuries were hands and a third of injuries involved more than one body part. The most frequent type of injury was a full thickness burn (39.6 %), followed by mid dermal (24.1 %) and superficial (23.0 %) respectively. Conclusions: Firework related burns have distinct patterns of use and injuries amongst men and women with variations across states. Legislation and prevention are cornerstone to reducing the impact of burn related injuries.

Introduction: Acquired brain injuries (ABIs) form part of the caseload of occupational therapists treating adult clients with neurological conditions. One adjunct to treatment of the upper limb condition following ABI is splinting. Little is known about the occupational therapy splinting practices in this field. This study aimed to describe these practices within a South African context. Method: A quantitative, cross-sectional survey design was utilised. A convenience sample of occupational therapists from across South Africa completed a survey. The survey comprised of demographic factors; types of splints used; wear schedule regimens during the motor recovery phases and influencing factors. Data were analysed using Statistical Package for Social Sciences. Results: Fifty-two participants (n = 115) completed the survey, representing a 45.2% response rate. Participants (52.9% (n = 27) indicated that splints are provided to 25% of clients with ABI. Splints are used to maintain soft tissue length and to ensure correct biomechanical alignment. Conclusions: Splinting for clients with ABI in South Africa is used as a preventative and maintenance approach. Failing more high-level evidence to support the use of splints for clients with ABI, therapists should consider the client-, therapist- and environment-related factors when determining the suitability and appropriateness of splinting clients with ABI.

The article explains the aesthetic element of the hand in the artworks of Slovenian regionalist painter Ive Å ubic (1922â1989). It elaborates the reasons why the author believes that Å ubicâs work was a unique combination of regionalism and partisan art. During his professional life, after he participated in the partisan uprising against occupational forces in WW II, Å ubic was considered a genuine partisan painter. He was highly praised by the Communist establishment, and he received several prestige awards. However, after the middle of the 1950s, when he slowly and quietly withdrew from the public life, he gradually became nostalgic. The hands on his paintings and public murals, portrayed as overworked hands with thick fingers and knuckles affected by hard farm work, are the central link between Å ubicâs experiences of war and his perception of the once genuine experience of rural life in Poljane Valley, lost for good.

The acute management of deep burns to the dorsum of the hand and fingers represents a challenge for the reconstructive surgeon. The exposure of osteo-tendinous structures often requires flap coverage, in a context where loco-regional or free flaps are not always feasible. The aims of reconstruction are to preserve a maximum of digital length, provide supple tissue, obtain protective sensitivity, and achieve a functional hand at 1 year. We report here on a series of 8 deep burns to the dorsum of the hand. Six hands were covered by Colson abdominal flap-graft and two by pedicled inguinal flap. Four out of 6 patients were reviewed in consultation, 1 patient was lost to follow-up, and 1 patient died. Clinical evaluation was performed by a surgeon other than the operator. Functional results are highly variable. Coverage time varies according to lesion depth and patient severity. Flap weaning took place at an average of 30 days. DASH scores ranged from 17.5 to 93/100, with average to poor total active motion (TAM) scores. The aesthetic result was satisfactory, with a Vancouver score of 4.5/13 on average, and an overall patient opinion of 3.75/10 on the POSAS scale. For deep burns to the dorsum of the hand and fingers, local flaps are rarely possible, and loco-regional flaps are not feasible in cases of associated upper limb damage. For medium to large surface areas, pedicled inguinal flaps and pocketing are two reliable techniques. Nevertheless, they require relative immobilization of the upper limb, which leads to stiffness. The question of digital pinning in the intrinsic or straight position remains unresolved, and does not appear to prevent secondary deformities. There is also a learning curve for these two flaps, even though they are reputed to be easy to lift. McGregor's flap or pocketing can be weighed against free flaps. However, the operating time is long, the surgical technique is complex, and vascular damage is common in the burn patient population. Although there have been enormous technical advances since their descriptions, the pedicled inguinal flap and pocketing remain alternatives to be considered in the acute management of deep burns to the dorsum of the hand. In this presentation, we propose a surgical management algorithm to situate these two techniques in the plastic surgeon's therapeutic armament. [ABSTRACT FROM AUTHOR]

ABSTRACT Objective: To determine the epidemiological profile of patients treated at a philanthropic hospital specialized in Orthopedics and Traumatology, located in a significant urban center, and evaluate the efficacy of initial empirical antibiotic treatment. Methods: Patients diagnosed with hand infections from September 2020 to September 2022 were included, excluding cases related to open fractures or post-surgical infections and those with incomplete medical records. The chi-square test was performed using STATISTICA ® software to correlate various variables. Results: A total of 34 patients participated, including 24 men and 10 women, with an average age of 41.9 years. Most male patients had Diabetes Mellitus, HIV, and drug addiction, and they resided in urban areas. Half of the patients did not report any apparent trauma. The most common infectious agent was Staphylococcus aureus*. Nearly 62% of patients required a change in the initial antibiotic regimen, with Penicillin being the most frequently substituted medication. Beta-lactam antibiotics and Quinolones were the most effective. Conclusion: These results suggest the importance of carefully evaluating the epidemiological profile of patients with acute hand infections and improving initial empirical treatment to ensure appropriate and effective therapy.

Degenerative collagenous plaques of the hands is an underrecognized acquired dermatosis characterized by slowly progressive linear depressed bands appearing symmetrically at the margins of palmar and dorsal skin of the hands. It is more common in the elderly and is believed to result from chronic pressure and ultraviolet radiation. We present an elderly woman with degenerative collagenous plaques of the hands to highlight an underrecognized rare dermatosis.

Rheumatoid arthritis (RA) is a chronic autoimmune disease characterized by symmetric polyarthritis that can lead to joint deformity, disability, and osteoporosis. We aimed to evaluate whole hand and regional BMD in RA patients compared to controls. In addition, we evaluated the BMD of dominant versus non-dominant hands in healthy subjects. We included adult female and male RA patients and control subjects matched by age, sex, and BMI. BMD (g/cm2) was measured by DXA in lumbar spine (LS), whole hand, and three regions of interest: carpus, metacarpal bones, and phalanges. Results: 44 control subjects (49.5 ± 11.8 y) and 60 with RA (52.7 ± 12.7 y) were included. Significant lower BMD in RA patients was found in LS (−8.7%), dominant whole hand (−9.5%), carpus, metacarpal bones, and phalanges, and non-dominant whole hand (−8.7%), metacarpal bones, and phalanges compared to controls. A significant positive correlation was found between LS and whole-hand BMD (dominant r =.63, non-dominant r =.67). Finally, the whole hand, metacarpal bones, and carpus BMD measurements were significantly higher in the dominant hand compared to the non-dominant hand without differences in the phalangeal ROI. In conclusion, hand BMD was significantly lower in RA patients compared to control subjects and there was a significant correlation with LS BMD. We demonstrated that BMD measurements of the whole-hand, and different ROI (carpus, metacarpal bones, and phalanges) by DXA would be an easily reproducible technique to evaluate bone loss. In addition, the whole hand, metacarpal bones and carpus BMD measurements were significantly higher in the dominant hand compared to the non-dominant hand without differences in the phalanges.

Abstract Background Hand eczema (HE) is a highly prevalent, recurrent, and multifactorial disease. It encompasses a group of eczematous diseases that affect the hands, etiologically classified into irritant contact dermatitis (ICD), allergic contact dermatitis (ACD) and atopic dermatitis (AD). Few epidemiological studies in Latin America have investigated the characteristics of patients with this condition and the origin of the disease. Objectives To analyze the profile of patients diagnosed with HE submitted to patch tests aiming to determine its etiology. Methods A retrospective descriptive study was carried out on epidemiological data and patch tests of patients with HE treated at a tertiary hospital in the city of São Paulo from January 2013 to December 2020. Results A total of 173 patients were studied, whose final diagnosis was 61.8% of ICD, 23.1% of ACD and 5.2% of AD, with diagnostic overlap in 42.8% of the cases. The main positive and relevant patch tests were: Kathon CG (42%), nickel sulfate (33%), and thiuram mix (18%). Study limitations The number of treated cases and socioeconomic profile was limited to a vulnerable population group. Conclusion HE is a diagnosis in which overlapping etiologies are frequent, with the main sensitizers identified in ACD being Kathon CG, nickel sulfate and thiuram mix.

Abstract Background Estimating or predicting stature, using fragments of the body or components of the human skeleton, for this purpose, originates from the idea of proportionality between the different parts of the body. The aim of this study is to estimate stature from anthropometric measurements of the hands (length and width). The sample consisted of 300 individuals from a quilombola community in northeastern Brazil, 150 males and 150 females. All people from the quilombola community, enjoying good general health, were included, and those people who presented deformities of the hand, spine, and lower limbs were excluded. Result The correlation coefficients between stature and hand length values were positive and moderate. As for females, the correlation between stature and lengths of the right and left hands were respectively 0.574 (p

Using excerpts selected from a corpus of our films, we show the construction of manual thinking. We put these extracts in dialogue with each other, based on the theme of gesture that run through them. We analyse the gesture of sport and work. The gesture speak to us of masculine and feminine skills and know-how. We pay particular attention to the body, and more specifically to the hands, because they are an expression of the social and bodily identity of the person(s) filmed and are the "extension of manual thinking".

Atopic dermatitis (AD) is severely burdensome, and there has been poor characterization of any differences in impact based on the area affected. To estimate the prevalence and HRQoL impact of head/face/neck/hand (HFNH) involvement among patients with moderate-to-severe atopic dermatitis. All TARGET-DERM AD registry patients with moderate/severe Investigator Global Assessment (vIGA-AD) were assessed using the Patient Oriented SCORing Atopic Dermatitis, Patient Oriented Eczema Measure (POEM) and the (Children's) Dermatology Life Quality Index ((C)DLQI). 541 participants met the criteria (75.0% adults) and 84% (N = 453) reported HFNH involvement. HFNH and non-HFNH involved participants had similar characteristics; 55.2% female and 46.9% White. Compared to the non-HFNH involved, the involved had severe vIGA-AD (28.5% vs 16.3%, P =.02) and higher median body surface area affected (15% vs 10%, P ≤.01) and were twice as likely to have higher (C)DLQI and POEM scores. This was an analysis of real-world and patient reported outcome data. Real-world HFNH involved AD patients were associated with significantly worse quality of life, POEM/(C)DLQI, and more severe disease. Detailed assessments of specific areas affected by AD are needed to personalize treatment. [ABSTRACT FROM AUTHOR]

Muscular skeletal disorder is a difficult challenge faced by the working population. Motion capture (MoCap) is used for recording the movement of people for clinical, ergonomic and rehabilitation solutions. However, knowledge barriers about these MoCap systems have made them difficult to use for many people. Despite this, no state-of-the-art literature review on MoCap systems for human clinical, rehabilitation and ergonomic analysis has been conducted. A medical diagnosis using AI applies machine learning algorithms and motion capture technologies to analyze patient data, enhancing diagnostic accuracy, enabling early disease detection and facilitating personalized treatment plans. It revolutionizes healthcare by harnessing the power of data-driven insights for improved patient outcomes and efficient clinical decision-making. The current review aimed to investigate: (i) the most used MoCap systems for clinical use, ergonomics and rehabilitation, (ii) their application and (iii) the target population. We used preferred reporting items for systematic reviews and meta-analysis guidelines for the review. Google Scholar, PubMed, Scopus and Web of Science were used to search for relevant published articles. The articles obtained were scrutinized by reading the abstracts and titles to determine their inclusion eligibility. Accordingly, articles with insufficient or irrelevant information were excluded from the screening. The search included studies published between 2013 and 2023 (including additional criteria). A total of 40 articles were eligible for review. The selected articles were further categorized in terms of the types of MoCap used, their application and the domain of the experiments. This review will serve as a guide for researchers and organizational management. [ABSTRACT FROM AUTHOR]

Posing high-contact interactions is challenging and time-consuming, with hand-object interactions being especially difficult due to the large number of degrees of freedom (DOF) of the hand and the fact that humans are experts at judging hand poses. This paper addresses this challenge by elevating contact areas to first-class primitives. We provide end-to-end art-directable (EAD) tools to model interactions based on contact areas, directly manipulate contact areas, and compute corresponding poses automatically. To make these operations intuitive and fast, we present a novel axis-based contact model that supports real-time approximately isometry-preserving operations on triangulated surfaces, permits movement between surfaces, and is both robust and scalable to large areas. We show that use of our contact model facilitates high quality posing even for unconstrained, high-DOF custom rigs intended for traditional keyframe-based animation pipelines. We additionally evaluate our approach with comparisons to prior art, ablation studies, user studies, qualitative assessments, and extensions to full-body interaction. [ABSTRACT FROM AUTHOR]

Antisepsis of the hands of medical personnel is one of the most important steps in the process of patient care, since direct contact can cause the cross-transfer of potentially pathogenic microorganisms at surgical sites. This study aimed to analyze the prevalence of microorganisms on the hands of 131 surgeons in a university hospital before the surgical procedure. Swabs were collected from each clinician's hands before and after handwashing. The samples were placed in a transport medium and immediately delivered to a private clinical analysis laboratory from São Luis-Maranhão. The microorganisms were identified by ionization source mass spectrometry and matrix-assisted laser desorption (MALDI-TOF), and antibiotic susceptibility tests (AST) were performed using the Vitek2 and Phoenix-BD automated system. The results showed a high frequency (100%) of microorganisms before handwashing, but after surgical antisepsis, the rate dropped significantly (p < 0.05) to 27.5%. The gram-positive species most detected were Staphylococcus spp. and Micrococcus luteus, representing 83.9%, followed by gram-negative species, Stenotrophomonas maltophilia, Acinetobacter baumanii, Pseudomonas aeruginosa, Pseudomonas gessardi, Pantoea septica, Serratia marcescens, and Burkholderia lata. The effectiveness of hand antisepsis was 72.5%, demonstrating that surgeons' hands are an important source of microorganisms that can cause infections in hospitalized patients in different care settings.

To investigate risk, risk factors and effects on adherence to adequate clinical standards, of burnout and depression in veterinary anaesthesia residents. Closed online cross-sectional survey study. A sample of 89 residents registered to the European and/or the American Colleges of Veterinary An (ae)sthesia and Analgesia out of a total of 185. A link to access an online questionnaire, which included the Maslach Burnout Inventory-Human Services Survey (MBI-HSS), the Harvard National Depression Screening Day Scale (HANDS) and 28 questions developed to assess adherence to adequate clinical standards, was sent by email to 185 residents. The three components of the MBI-HSS namely emotional exhaustion (EE), depersonalization and reduced personal accomplishment were analysed separately. Analysis of proportions and two-step regression statistical modelling were used for data analysis, and p values < 0.05 were considered statistically significant. The response rate was 48%. Based on HANDS and MBI-HSS scores, 49% of the residents were at high risk of both depression and burnout. These residents expressed greater concern of delivering inadequate animal care (p < 0.001), of decreased quality of supervision during COVID-19 (p = 0.038) and of negative impact of the pandemic on their training programme (p = 0.002) than residents at low-to-moderate risk. Working in a clinical environment for ≥ 60 hours/week was a risk factor for both depression (p = 0.016) and EE (p = 0.022), while female sex was a risk factor for EE only (p = 0.018). A large proportion of residents is at high risk of depression and burnout, a scenario likely worsened by the pandemic. The findings of this study suggest that reducing the clinical workload and increasing the level of support and supervision may help to improve residents' mental health. [ABSTRACT FROM AUTHOR]

According to the standard interpretation of Mark 7:19b—"Thus Jesus declared all foods clean"—Jesus nullifies the dietary commandments of the Torah. A close examination, which draws together some important recent research on this text, reveals that this is a misreading. Instead, Mark maintains a consistent portrait of Jesus as one who is faithful to Torah, even to the dietary laws. This will be shown through a close study of the syntax, literary context, sociocultural situation, Matthean parallel, and early church reaction. This article offers a close look at the standard interpretation, followed by an evaluation of two alternate readings. [ABSTRACT FROM AUTHOR]

• Background level of blood on hands in the general population is extremely low. • Background level of semen on the hands in the general population is also low. • Large number of samples with low level background of α-amylase found using Phadebas. • Limited value in using the Phadebas® tube test to detect saliva on hand samples. • RSID™-Saliva test more suitable for the presence of saliva on hands. Forensic scientists are often asked to assist the court by evaluating the significance of finding body fluids on the hands of an individual; however, there is an absence of published data regarding the background levels of body fluids on hands. Whilst the scientist can use casework experience to inform the courts on the significance of the results, it would be advantageous to have data which could assist with this interpretation. This study was designed to ascertain the background levels of blood, semen, saliva, hairs/fibres and staining/debris on hands in the general population by sampling from delegates attending a scientific conference. The findings suggest that approximately one third of the population would be expected to have hairs or fibres on their hands and that females are more likely to have visible staining on their hands than males. Presumptive tests for blood and semen yielded negative results in all samples; however, almost 2 % of the samples were found to contain a very low number of sperm heads. In contrast, the majority of samples tested positive for the presence of saliva using the presumptive Phadebas® amylase test. The data supports the caution applied by forensic practitioners when evaluating the presence of saliva detected using the presumptive Phadebas® amylase test based on the lack of specificity and indicates that the RSID™-Saliva test would be more suitable to use.

Robots face a rapidly expanding range of potential applications beyond controlled environments, from remote exploration and search-and-rescue to household assistance and agriculture. The focus of physical interaction is typically delegated to end-effectors-fixtures, grippers or hands-as these machines perform manual tasks. Yet, effective deployment of versatile robot hands in the real world is still limited to few examples, despite decades of dedicated research. In this paper we review hands that found application in the field, aiming to discuss open challenges with more articulated designs, discussing novel trends and perspectives. We hope to encourage swift development of capable robotic hands for long-term use in varied real world settings. The first part of the paper centers around progress in artificial hand design, identifying key functions for a variety of environments. The final part focuses on the overall trends in hand mechanics, sensors and control, and how performance and resiliency are qualified for real world deployment.

Irritant contact dermatitis is the most common form of both contact dermatitis and occupational skin disease. The diagnosis of irritant dermatitis is often difficult, given the lack of confirmatory testing, and it is usually diagnosed confidently only after allergic contact dermatitis has been excluded with patch-testing. Early recognition, prevention and treatment are the mainstays of management, particularly when it is work-related. This article provides a comprehensive summary of the disease, clinical presentations and management. [ABSTRACT FROM AUTHOR]

Background: Estimating or predicting stature, using fragments of the body or components of the human skeleton, for this purpose, originates from the idea of proportionality between the different parts of the body. The aim of this study is to estimate stature from anthropometric measurements of the hands (length and width). The sample consisted of 300 individuals from a quilombola community in northeastern Brazil, 150 males and 150 females. All people from the quilombola community, enjoying good general health, were included, and those people who presented deformities of the hand, spine, and lower limbs were excluded. Result: The correlation coefficients between stature and hand length values were positive and moderate. As for females, the correlation between stature and lengths of the right and left hands were respectively 0.574 (p < 0.0001) and 0.612 (p < 0.0001). Conclusion: The measure that best correlated with stature in the quilombola community in northeastern Brazil was hand length for both sexes, with the highest correlation for females.

Background: At present, the clinical diagnosis of white matter change (WMC) patients depends on cranial magnetic resonance imaging (MRI) technology. This diagnostic method is costly and does not allow for large-scale screening, leading to delays in the patient's condition due to inability to receive timely diagnosis.Objective: To evaluate whether the burden of WMC is associated with the degree of invisible hand tremor in humans.Methods: Previous studies have shown that tremor is associated with WMC, however, tremor does not always have imaging of WMC. Therefore, to confirm that the appearance of WMC causes tremor, which are sometimes invisible to the naked eye, we achieved an optical-based computer-aided diagnostic device by detecting the invisible hand tremor, and we proposed a calculation method of WMC volume by using the characteristics of MRI images.Results: Statistical analysis results further clarified the relationship between WMC and tremor, and our devices are validated for the detection of tremors with WMC.Conclusions: The burden of WMC volume is positive factor for degree of invisible hand tremor in the participants without visible hand tremor. Detection technology provides a more convenient and low-cost evaluating method before MRI for tremor diseases. [ABSTRACT FROM AUTHOR]

Background: Fireworks are often used to celebrate holidays and events. With novel designs and availability, there is potential for blast and burn injuries that can impact livelihood and function. This study aims to describe and analyse firework-related burns in adults across New South Wales and the Australian Capital Territory. Methods: A retrospective statewide review was performed from January 2010 to December 2020 at the adult burns units. All firework-related burn injuries older than 18 years that attended or were referred to the burns unit were included. Results: There were 203 patients with a firework-related burn injury. The male to female ratio was 4:1 with an average age of 32.2 years. Men were 5.2 years younger than women (31.2 vs 36.4, p = 0.010). Men were more likely to have firework-related injuries on non-holidays, whereas women were more likely on holidays (p = 0.050). Men were more likely to operate fireworks after consuming alcohol resulting in burns than women (34.4% vs 12.5%, p = 0.007). Sparklers were more common amongst women, whereas fireworks had higher proportions amongst men (p = 0.009). The most common site of injury was the hands. The most frequent type of injury was a mid-dermal burn (61.6%), followed by superficial (25.2%), and full thickness (13.2%) respectively. The operative rate was 17.7% with a mean total length of stay of 2.2 days (range: 1–12). Conclusions: Firework-related burns have distinct patterns of use and injuries amongst men and women. Alongside legislation, awareness of the potential hazards for shopgood fireworks such as sparklers is critical for future prevention campaigns. Level of evidence: Level III, Risk/Prognostic.

Objective: Prolonged morning stiffness (>60 min) is considered a symptom of inflammatory arthritis, but has a poor discriminative ability. Knowledge about morning stiffness in patients with hand osteoarthritis (OA) is lacking. We therefore studied morning stiffness in patients with hand OA.Design: Patients with primary hand OA according to their treating rheumatologist in the Hand OSTeoArthritis in Secondary care (HOSTAS) cohort were studied. Severity of morning stiffness were examined with Australian/Canadian hand OA index (AUSCAN) and presence and duration of morning stiffness was examined with a standardized questionnaire. Association of patient and disease characteristics with prolonged morning stiffness (>60 min) were analyzed with logistic regression.Results: In total 519 of 538 patients had available data about duration of morning stiffness, of whom 89 (17%) had prolonged morning stiffness. Severity of stiffness was mild in 158 of 525 (30%), intermediate in 194 (37%), severe in 97 (18%) and extreme in 19 (4%) patients. Patients with prolonged morning stiffness reported more pain, worse physical function and had a reduced mental and physical quality of life. Patients with prolonged morning stiffness also had more severe radiographic disease, although the association did not reach statistical significance.Conclusions: Prolonged and severe morning stiffness are frequently present in patients with hand OA. Patients with these symptoms report more pain in general and have a lower quality of life than patients that do not report these symptoms. Prolonged morning stiffness does not preclude a diagnosis of hand OA. [ABSTRACT FROM AUTHOR]

Interpersonal interactions rely on various communication channels, both verbal and non-verbal, through which information regarding one's intentions and emotions are perceived. Here, we investigated the neural correlates underlying the visual processing of hand postures conveying social affordances (i.e., hand-shaking), compared to control stimuli such as hands performing non-social actions (i.e., grasping) or showing no movement at all. Combining univariate and multivariate analysis on electroencephalography (EEG) data, our results indicate that occipito-temporal electrodes show early differential processing of stimuli conveying social information compared to non-social ones. First, the amplitude of the Early Posterior Negativity (EPN, an Event-Related Potential related to the perception of body parts) is modulated differently during the perception of social and non-social content carried by hands. Moreover, our multivariate classification analysis (MultiVariate Pattern Analysis - MVPA) expanded the univariate results by revealing early (

The discipline of embodied cognitive science and associated concept of intercorporeality provide the theoretical framework of our analysis of Proverbs 31:10–31. This essay fleshes out the underlying cognitive and meaning-making processes and entailments inherent in the valiant woman’s use of her hands and body as depicted in the poem. The valiant woman is contrasted with the hands and body of the sluggard fool to unveil how the activity or inactivity of the hands (and body) substantially affects the knowing of the valiant woman and the fool. Knowledge and wisdom emerged and are shaped by one’s hands and bodily interaction with the real world.
