Placement Of Fingers Research Articles

The comparison of Kardia Mobile and Hartmann Veroval 2 in 1 in detecting first diagnosed atrial fibrillation.

Atrial fibrillation (AF) is the leading cause of stroke. The European Society of Cardiology (ESC) advises opportunistic AF screening among patients aged ≥ 65 years. Considering this, the aim herein, was compare the feasibility of two different systems of smartphone-based electrocardiogram (ECG) recordings to identify AF among those without a previous arrhythmia history. Prospective AF screening was conducted at six pharmacies using Kardia Mobile and Hartmann Veroval 2 in 1. A single-lead ECG was acquired by the placement of fingers on the pads. A cardiologist evaluated findings from both devices. Atrial fibrillation was identified in 3.60% and previously unknown AF was detected in 1.92% of the study participants. Sensitivity and specificity of the Kardia application in detecting AF were 66.7% (95% confidence interval [CI] 38.4-88.2%) and 98.5% (95% CI 96.7-99.5%), and for Veroval 10.0% (95% CI 0.23-44.5%) and 94.96% (95% CI 92.15-96.98%), accordingly. Inter-rater agreement was k = 0.088 (95% CI 1.59-16.1%). Mobile devices can detect AF, but each finding must be verified by a professional. The Kardia application appeared to be more user-friendly than Veroval. Cardiovascular screening using mobile devices is feasible at pharmacies. Hence it might be considered for routine use.

Knowledge and Attitudes of Parents Regarding Digit Sucking Habit in Children in Pune: A Questionnaire-based Cross-Sectional Study

Introduction: Digit sucking is a most common oral fixation observed in children, which involves placement of thumb or fingers into the mouth. Knowledge of the risk factors for the presence of this habit helps to provide a better understanding of the phenomena and is of great significance to the establishment of preventive measures, which can avoid the damage caused by the persistence of these habits. Aim: To evaluate the knowledge and attitude of parents of children aged between 3-6 years regarding digit sucking habit. Materials and Methods: A cross-sectional study was carried out in the Department of Paediatric and Preventive Dentistry, belonging to urban and semiurban area of Pune, Maharashtra, India from December 2020 to May 2021. A total of 310 parents of children, aged between 3-6 years were included. A closeended questionnaire was administered to parents to assess their knowledge and attitude regarding digit sucking habit in children. Completely filled questionnaires were considered for result synthesis. The data obtained was tabulated and descriptive data were statistically analysed using software International Business Machines (IBM) Statistical Package for the Social Sciences (SPSS) version 21.0. Results: Although 229 (73.9%) of parents agreed that for achieving good oral health prevention of digit sucking habit is essential, but 197 (63.5%) parents were unaware of the predisposing factors for digit sucking habit. A total of 195 (62.9%) parents did not agree that inadequate parental attention may lead to thumb sucking habit. A total of 197 (63.5%) parents agreed that prolonged digit sucking can cause misaligned teeth but majority of the parents 205 (66.1%) and 166 (53.5%) disagreed on its effects on facial growth and speech respectively. A total of 219 (70.6%) parents did not receive any scientific information or counselling from healthcare worker regarding sucking habit. A total of 299 (96.5%) of parents agreed that guidance from healthcare workers is needed regarding oral habits in children. Conclusion: Present study concluded that the attitude towards learning about digit sucking habit was good the knowledge of the study participants was poor.

Addressing the MSICS learning curve: identification of instrument-holding techniques used by experienced surgeons.

To identify instrument holding archetypes used by experienced surgeons in order to develop a universal language and set of validated techniques that can be utilized in manual small incision cataract surgery (MSICS) curricula. Experienced cataract surgeons performed five MSICS steps (scleral incision, scleral tunnel, side port, corneal tunnel, and capsulorhexis) in a wet lab to record surgeon hand positions. Images and videos were taken during each step to identify validated hand position archetypes. For each MSICS step, one or two major archetypes and key modifying variables were observed, including tripod for scleral incision, tripod-thumb bottom for scleral tunnel, underhand-index to thumb grip for side port, index-contact tripod for corneal entry, and tripod-forceps for capsulorhexis. Key differences were noted in thumb placement and number of fingers supporting the instrument, and modifying variables included index finger curvature and amount of flexion. Identification of optimal hand positions and development of a formal nomenclature has the potential to help trainees adopt hand positions in an informed manner, influence instrument design, and improve surgical outcomes.

РОЛЬ АППЛИКАТУРЫ В ПРОЦЕССЕ ОБУЧЕНИЯ СЛАБОВИДЯЩИХ СТУДЕНТОВ В КЛАССЕ ДОМРЫ

The cognitive activity of executor begins with motor sensations and musical-auditory perceptions, transformed into ideas. One of the means to replace the lack of visual information of musicians with the partial or total loss of sight is the development along with hearing of tactile sensitivity, motor activity of fingers and hands. The capacity to build and to convert acquired practices depends on the development of coordination ability of the executor. The article examines the application of the intelligent, expedient, rational fingering, which includes narrow technical, timbre, articulation and dynamic functions. The basis of the fingering of plucked string instruments is the division of the neck into positions and the use of different types of placement of the left hand fingers. Detailed acquaintance of the domrist with the form of movements and their sensual orientations gives the opportunity of planning and effective control, accelerates mastery and formation of corresponding skills. The objective condition for the successful teaching of visually impaired students is the choice of convenient fingering, depending on the order of the positions study, versions of their change, as well as the possibility of using a narrowed and extended finger arrangement.

Feasibility of Atrial Fibrillation Screening With Mobile Health Technologies at Pharmacies.

Atrial fibrillation (AF) is the most common cardiac arrhythmia. Thus, the aim of our study was to evaluate the smartphone-based electrocardiogram (ECG) recordings aimed at AF screening at Polish pharmacies. Prospective AF screening among patients aged ≥65 years was conducted at 10 pharmacies using Kardia Mobile with a dedicated application (Kardia app). Prior AF was a study exclusion criterion. CHA2DS2-VASc score (congestive heart failure, hypertension, age, diabetes mellitus, previous stroke/transient ischemic attack, female sex, and vascular disease) has been collected from every patient. A single-lead ECG has been acquired by the placement of fingers from each hand on the pads. Kardia app diagnosis has been evaluated by the cardiologist. A total of 525 ECGs were performed. Kardia app diagnosis was provided in 490 cases. In 437 (89.18%) cases, it was "normal" rhythm, in 17 (3.47%) recordings "possible AF," in 23 (4.69%) ECGs "unreadable," and in 13 (2.65%) "unclassified". After the cardiologist reevaluation, the new AF was identified in 7 (1.33%) patients. Sensitivity and specificity of Kardia app in detecting AF was 100% (95% confidence interval [CI]: 71.5%-100%) and 98.7% (95% CI: 97.3%-99.5%), respectively. The positive predictive value was 64.7% (95% CI: 38.3%-85.7%) and the negative predictive value was 100% (95% CI: 99.2%-100%). CHA2DS2-VASc score was 2.14 ± 0.69 for those with new AF and 3.33 ± 1.26 in the non-AF group. Kardia app is capable of fast screening and detecting AF with high sensitivity and specificity. The possible diagnosis of AF deserves additional cardiological evaluation. The results obtained in patients with low CHA2DS2-VASc score and "silent" AF confirm the importance of routine AF screening. Cardiovascular screening with the use of mobile health technology is feasible at pharmacies.

The Signum Harpocraticum in the 8th-century Christian Art of Nubia

The Egyptian god Horus was known from the second millennium BC as “the child with a finger in his mouth”. Hieroglyphics show that the placement of fingers onto the lips pertains to the believer’s responsibility to stay silent in the presence of the divine out of respect. In Eastern Christianity, the ancient Egyptian prohibition of speaking when God is present – now effectuated in churches – was continued more prominently both in texts and less often iconography. In general, the significance of the gesture of silence is defined as the appropriate behaviour that the faithful should adopt when confronting god in their prayers or when entering religious spaces. However, textual and iconographical evidence shows that this particular gesture was multilayered and could be explained on a theological or philosophical level depending on the era and region it appears. This article explores the semiotics of the silence gesture for a female saint in the 8th-century Cathedral of Paul, in Faras, Nubia.

How Objects Are Grasped: The Interplay between Affordances and End-Goals

BackgroundSubstantial literature has demonstrated that how the hand approaches an object depends on the manipulative action that will follow object contact. Little is known about how the placement of individual fingers on objects is affected by the end-goal of the action.Methodology/Principal FindingsHand movement kinematics were measured during reaching for and grasping movements towards two objects (stimuli): a bottle with an ordinary cylindrical shape and a bottle with a concave constriction. The effects of the stimuli's weight (half full or completely full of water) and the end-goals (pouring, moving) of the action were also assessed. Analysis of key kinematic landmarks measured during reaching movements indicate that object affordance facilitates the end-goal of the action regardless of accuracy constraints. Furthermore, the placement of individual digits at contact is modulated by the shape of the object and the end-goal of the action.Conclusions/SignificanceThese findings offer a substantial contribution to the current debate about the role played by affordances and end-goals in determining the structure of reach-to-grasp movements.

Toe gangrene in an infant subsequent to application of adult-type pulse oximeter probe for 10 min

We present a case of ischemic changes after application of an adult pulse oximeter probe in an infant for a short period of only 10 min. To understand the physiology behind this mishap, we studied pressure exerted by the adult pulse oximeter probe on simulated fingers (fluid-filled pouches), which were filled under gravity through the three-way stopcock. A catheter was placed inside the pouch to continuously measure the pressure. The experiment was performed on different sizes of the finger-shaped pouches and by varying the positioning of the pouches in the pulse oximeter. It was observed that pressure exerted by the pulse oximeter was directly proportional to the extent to which it was stretched after placement on the fluid-filled pouches of different sizes. In the fully extended position, the pressure exerted was higher (up to 30 mmHg) than in the fully collapsed position (4 mmHg). Higher pressures were caused by greater stretch of the probe. This could occur due to larger fingers and closer placement of fingers to the hinge of the probe.

Endotracheal tube as a nasogastric tube introducer

To the Editor, Nasogastric tube (NGT) insertion is a procedure performed routinely in critical care settings. However, NGT placement often proves to be a daunting task, especially in the setting of anesthetized/uncooperative patients with anatomic distortion (i.e., patients with cervical spine instability and/or restricted neck movement) and an endotracheal tube (ETT) already in situ for airway protection and support of the respiratory system. In fact, serious complications secondary to NGT placement appear often in the literature. Therefore, NGT insertion may be a complex procedure that requires skill, experience, and the ability to improvise if it does not proceed smoothly. A 63-year-old male patient, who was sedated and mechanically ventilated in our intensive care unit, had a hard cervical collar in place after sustaining severe traumatic brain injury, cervical spine fracture, and multiple long bone fractures in a motor vehicle accident. The NGT was unintentionally removed during routine patient care, and despite many gentle and prolonged attempts, the on-call physicians’ efforts to re-insert the NGT were unsuccessful. The presence of the cervical collar created poor laryngoscopic views, even with the left molar approach, and the patient’s cervical spine injury did not allow maneuvres that could facilitate NGT insertion, such as neck flexion, turning the head laterally, lateral neck pressure, and forward displacement of the larynx. To this end, a number of techniques to advance the NGT were attempted without success, including blind insertion plus a combination of direct laryngoscopy and use of Magill forceps, placement of fingers in the posterior pharynx to guide the NGT tip downward, deflation of the ETT cuff, and use of a frozen NGT. Finally, a 9.5-mm internal diameter ETT (‘‘conduit’’ ETT) was placed in the oropharynx and—under direct laryngoscopy—was continually kept in contact with the posterior pharyngeal wall and behind the ETT already in place while simultaneously being advanced gently and as far as possible into the esophagus. A well-lubricated 14-Fr NGT was threaded into the ‘‘conduit’’ ETT and was advanced into the full length of the stomach without difficulty during the first attempt. Afterward, the ‘‘conduit’’ ETT was withdrawn and the NGT was pulled back, positioned at the appropriate length, and fastened in the usual way. It is worth noting that no change of head or neck position, no ETT cuff deflation, and no involvement of an assistant were necessary during this alternative mode of NGT insertion. The only technical requirement was to ensure that the ‘‘conduit’’ ETT diameter could accommodate the NGT, including its funnel-shaped proximal end. We did not determine fibreoptically the point where the NGT met resistance and was successfully bypassed by the ‘‘conduit’’ ETT. However, it has been previously shown that the most common sites of resistance at the laryngeal level are the piriform sinuses and the arytenoid cartilages. In conclusion, the use of an ETT as an introducer can facilitate NGT insertion in difficult settings. This alternative mode of NGT insertion is easy, inexpensive, and widely available in the operating room and the intensive care unit. In our view, it is worth considering this blind approach before the physician resorts to other techniques (i.e., videolaryngoscopy) that are either more expensive or that necessitate the involvement of additional equipment.

On the Complexity of Classical Guitar Playing: Functional Adaptations to Task Constraints

The authors performed a behavioral study of the complexity of left-hand finger movements in classical guitar playing. Six professional guitarists played movement sequences in a fixed tempo. Left-hand finger movements were recorded in 3 dimensions, and the guitar sound was recorded synchronously. Assuming that performers prefer to avoid extreme joint angles when moving, the authors hypothesized 3 complexity factors. The results showed differential effects of the complexity factors on the performance measures and on participants' judgments of complexity. The results demonstrated that keeping the joints in the middle of their range is an important principle in guitar playing, and players exploit the available tolerance in timing and placement of the left-hand fingers to control the acoustic output variability.

Computer-vision-based approach to personal identification using finger crease pattern

This paper describes a biometric approach for automated personal identification based on computer vision. It employs a CCD camera for imaging creases on the inner side of the fingers which are subsequently analysed to generate a wide line integrated profile pattern. Identification is made by comparing the submitted biometric pattern of an individual against the reference obtained at the time of enrolment. The complications in the image processing module have been eliminated by providing consistent illumination and positioning aids for proper placement of fingers. The paper also discusses scope of work that can be carried out to reduce false acceptance and false rejection rates further.

A Sign Language Manual (review)

Reviews The Language of Life, Elizabeth A. Gochnour & Theresa B. Smith, 411 pp., $7.50 paperback, Interstate Printers & Publishers, 19-27 N. Jackson St., Danville, IL 61832, 1984 (second edition). This book is a revised edition of a class language -reading program. It has been written for post-high school deaf people from a protective environment who not only need to develop language skills, but also need to develop a better understanding of the world around them. The Language of Life contains 36 lessons, providing one lesson per school week. The language used is carefully devised so that new vocabulary and idioms are introduced gradually and are reviewed frequently. Therefore, lessons should be assigned consecutively rather than randomly. In the preliminary pages, the authors give a brief but excellent statement for teachers, explaining the nature and purpose of each of the 36 lessons. Each lesson has six components which help teachers contribute to students' development : "The Story", "For the Class to Talk About", "Things to Do", "Enrichment Suggestions ", "Difficult Vocabulary", and "Exercises." Hopefully, this book will help young, overprotected deaf people cope with some of the difficulties they may encounter in their personal and professional lives.

Thomas, 2600 South First St., Springfield, IL 62717, 1984. There are two things I like about this manual in comparison with other sign language texts. A spiral binder allows the manual to lie flat during instruction or practice, and it has 32 chapters that include specific examples and cover more areas and signs than most texts. There are drawbacks, however. The price of $29.75 makes the text undesirable for the beginner with modest means. The biggest disappointment is that there are numerous errors: the drawings, although reasonably well done, frequently show the left hand while the description calls for the right hand. Some of the explanations accompanying the illustrations could be improved to enhance comprehension and retention of signs. Some signs appear to be local, if not incorrect. Incorrect placement of hand(s) or fingers is another common blunder. Had the manual been reviewed and mistakes corrected by a qualified person, it would have been an excellent book for schools, libraries, parents , and teachers. Robert R.
