ABSTRACT

The present study compared the effects of a footwear designed to enhance energy return (thermoplastic polyurethane, TPU) vs minimalist shoes on running economy (RE) and endurance performance. In this counterbalanced and crossover design study, 11 recreational male runners performed two submaximal constant-speed running tests and two 3-km time-trials with the two shoe models. Oxygen uptake was measured during submaximal constant-speed running tests in order to determine the RE at 12 km/h and oxygen cost of running (CTO2) at individual average speed sustained during the 3-km running time-trials wearing either of the two shoes. Our results revealed that RE was improved (2.4%) with TPU shoes compared with minimalist shoes (P=0.01). However, there was no significant difference for CTO2 (P=0.61) and running performance (P=0.52) comparing the TPU (710±60 s) and the minimalist (718±63 s) shoe models. These novel findings demonstrate that shoes with enhanced mechanical energy return (i.e. TPU) produced a lower energy cost of running at low (i.e., 12 km/h) but not at high speeds (i.e., average speed sustained during the 3-km running time-trial, ∼15 km/h), ultimately resulting in similar running performance compared to the minimalist shoe.

ABSTRACT

El objetivo fue analizar si el profesional de enfermería aplicaba el autocuidado en el uso del calzado en horario laboral. Es un estudio observacional, analítico, de corte trasversal con enfoque cuantitativo. La población estuvo constituida por 1.037 profesionales de Enfermería del Hospital de Clínicas, institución de carácter público, situada en la ciudad de San Lorenzo, Paraguay. Se incluyeron 366 profesionales de Enfermería a través de un muestreo probabilístico, la selección de la muestra fue multietápica con muestreo aleatorio simple. Se aplicó estadística descriptiva y chi2 para determinar asociaciones. Los hallazgos más relevantes fueron que mayoritariamente eran del grupo etario de 24 a 48 años con una media de 35 años; soltero, con una antigüedad de 10 años, con más de un empleo y del servicio de urgencias. Solo el 11,7% refirió conocer el calzado anatómico, sin embargo, 50,2% lo utilizaba. Más del 60% no tenía en cuenta las características del calzado anatómico al momento de adquirirlo, entre otros aspectos relacionados al utilizarlo en horario laboral. En el grupo etario de 31 a 35 años se concentró la mayor cantidad de trastornos músculo-esqueléticos (40%). En conclusión, el profesional de enfermería utilizaba de forma deficitaria el calzado adecuado; además, se ha encontrado evidencia de asociación (chi2 0,05) entre el tipo de calzado utilizado y la cantidad de trastornos músculo-esqueléticos que presentaba cada individuo


The objective was to analyze if the nursing professional applied self-care in the use of footwear during working hours. It was an observational, analytical, cross-sectional study with a quantitative approach. The population was constituted by 1,037 nursing professionals from the Hospital de Clínicas, a public institution, located in the city of San Lorenzo, Paraguay. The sample included 366 nursing professionals and the sampling wasprobabilistic while the selection of the multistage sample with simple random sampling. Descriptive statistics and Chi2 were applied to determine associations. The most relevant findings were that they were mainly in the age group of 24 to 48 years with an average of 35 years, single, with a career of 10 years, more than one job and from the emergency service. Only 11.7% referred to know the anatomical footwear, however, 50.2% used it. More than 60% did not take into account characteristics of the anatomical footwear at the time of purchase, among other aspects related to using it during working hours. The greatest number (40%) of musculoskeletal disorders were concentrated in the age group from 31 to 35 years. In conclusion, the nursing professional uses the right footwear in a loss-making way. In addition, evidence was found of an association between the type of footwear used and the number of musculoskeletal disorders that each individual presents

ABSTRACT

RESUMO Para a manutenção do equilíbrio, o organismo utiliza os sistemas visuais, vestibulares e proprioceptivos, que enviam informações para o sistema nervoso central acerca das condições do corpo com o objetivo de estabilizá-lo. Este estudo avaliou o efeito das palmilhas proprioceptivas sobre o equilíbrio postural estático e as dores musculoesqueléticas após dois meses de uso, por meio de uma pesquisa analítica longitudinal com 15 militares saudáveis do sexo masculino com média de idade de 34±7,5 anos. Eles foram submetidos à avaliação do equilíbrio por meio da plataforma Medicapteurs® e pelo protocolo CNT. Não houve diferença estatística para os desvios do corpo e velocidade do centro de pressão. A pressão plantar teve mudança estatisticamente significante para o pé esquerdo e o pé direito correspondendo a p=0,0001 e p=0,0007, respectivamente. Houve redução das médias de dores nos joelhos, pés e calcanhares e diminuição significativa da dor lombar, com p=0,0180. O equilíbrio estático não foi alterado significativamente com o uso das palmilhas proprioceptivas pelos militares, contudo elas proporcionaram melhor redistribuição das pressões plantares e parecem atenuar as dores musculoesqueléticas das extremidades inferiores. Por isso as palmilhas podem ser consideradas para esse grupo uma terapêutica de prevenção contra lesões relacionadas à sua atividade laboral.


RESUMEN Para mantener el equilibrio el cuerpo utiliza los sistemas visuales, vestibulares y propioceptivos, que envían información al sistema nervioso central sobre las condiciones del cuerpo para estabilizarlo. Este estudio evaluó el efecto de las plantillas propioceptivas sobre el equilibrio postural estático y los dolores musculoesqueléticas después de dos meses de uso, a través de una investigación analítica longitudinal con 15 soldados sanos con una edad media de 34±7.5 años. Ellos fueron sometidos a evaluación de equilibrio a través de la plataforma Medicapteurs® y por el protocolo CNT. No hubo diferencia estadística para las desviaciones del cuerpo y para la velocidad del centro de presión. La presión plantar tuvo un cambio estadísticamente significativo para el pie izquierdo y el pie derecho correspondiente a p=0.0001 y p=0.0007, respectivamente. Hubo una reducción en las promedio de los dolores en las rodillas, pies y talones y una disminución significativa en el dolor lumbar, con p=0.0180. El equilibrio estático no se modificó significativamente con el uso de plantillas propioceptivas por los militares, sin embargo, proporcionaron una mejor redistribución de las presiones plantares y parecen ablandar los dolores musculoesqueléticas en las extremidades inferiores. Por lo tanto las plantillas pueden considerarse para ese grupo como una terapia de prevención contra lesiones relacionadas con su actividad laboral.


ABSTRACT To maintain the balance, the body uses visual, vestibular and proprioceptive systems, which send information to the central nervous system about the body's conditions in order to stabilize it. This study evaluated the effect of proprioceptive insoles on static postural balance and musculoskeletal pains after two months of use, through a longitudinal analytical study with 15 healthy male soldiers with a mean age of 34±7.5 years. They were subjected to balance evaluation through the Medicapteurs® platform and by CNT protocol. There was no statistical difference for the deviations of the body and speed of the center of pressure. Plantar pressure had a statistically significant change for the left and the right feet, corresponding to p=0.0001 and p=0.0007, respectively. There was a reduction in the mean values of the pains in the knees, feet and heels and a significant decrease in lumbar spine pain, with p=0.0180. The static balance was not significantly altered with the use of proprioceptive insoles by the militaries; however, these insoles provided a better redistribution of plantar pressures and seem to attenuate the musculoskeletal pains of the lower extremities. Therefore, insoles can be considered as a prevention therapy against injuries for this group related to their work activity.

ABSTRACT

La carrera descalza ha sido ampliamente estudiada últimamente, pero poco se sabe de cambios anatómicos que produce en el pie. El objetivo de este estudio fue determinar estos cambios producidos de forma aguda y a largo plazo en sujetos que entrenan a pie descalzo. 29 sujetos divididos en dos grupos: Barefoot (BFGr) (n=17) y Shod (SGr) (n=12), realizaron un protocolo de efecto agudo consistente en correr durante 20 min sobre treadmill a 3.1 m/s y un protocolo de entrenamiento de 8 semanas de carrera de resistencia con aumento progresivo de volumen. BFGr realizó todas las sesiones a pie descalzo. Al finalizar cada protocolo se midió Foot Length (FL), Forefoot Width (FW), Hindfoot Width (HW), Navicular Height (NH), Arch Index (AI) y Maximum Surface (MS). Se efectuó ANOVA 3x2 para comprobar los efectos que el tiempo y la condición de calzado produjo. La condición de calzado produjo efectos significativos sobre todas las variables (FL: p=0.000, η2p=0.997; FW: p=0.000, η2p=0,997; HW: p=0.000, η2p= 0,994; NH: p=0.000, η2p=0.953; AI: p=0.000, η2p=0.898; MS: p=0.000, η2p=0.983) y el factor tiempo sobre AI (p=0.012, η2p=0.152) y MS (p=0.000, η2p=0.259). Hubo interacción significativa Tiempo x Condición en FW (p=0.036, η2p= 0.116) y NH (p=0.019, η2p= 0.143). MS aumentó luego del protocolo de efecto agudo (p=0.000) y a largo plazo (p=0.001) en BFGr. El porcentaje de sujetos con pie normal aumentó en BFGr y con pie plano aumentó en SGr. El entrenamiento de carrera a pie descalzo produce efectos, principalmente luego de un período de adaptación de 8 semanas, tendientes a un aumento armónico en la superficie de apoyo plantar con tendencia a una disminución relativa del área del mediopié, lo cual se tradujo en una disminución de sujetos con arco plantar de tipología plana.


Barefoot running has been studied extensively recently, but little is known of the anatomical changes that take place in the foot. The objective of this study was to determine the acute and chronic changes that are produced in subjects who train barefoot. 29 subjects divided into two groups, Barefoot (BFGr) (n=17) and Shod (SGr) (n=12), followed an acute effect protocol which consisted in running during 20 min on a treadmill at 3.1 m/s, and an eight-week long chronic effect protocol covering eight weeks of resistance running with progressively increasing volume. BFGr did all the sessions barefoot. At the end of each protocol Foot Length (FL), Forefoot Width (FW), Hindfoot Width (HW), Navicular Height (NH), Arch Index (AI), and Maximum Surface (MS) were measured. ANOVA 3x2 was run to verify the effects caused by time and the shod condition produced. Shod/ Unshod factor caused significant effects on all the variables (FL: p=0.000, η2p=0.997; FW: p=0.000, η2p=0,997; HW: p=0.000, η2p= 0,994; NH: p=0.000, η2p=0.953; AI: p=0.000, η2p=0.898; MS: p=0.000, η2p=0.983), and the time factor on AI (p=0.012, η2p=0.152) and MS (p=0.000, η2p=0.259). There was a significant Time x Condition interaction in FW (p=0.036, η2p=0.116) and NH (p=0.019, η2p= 0.143). MS increased after the acute (p=0.000) and the chronic (p=0.001) protocols in the BFGr. The percentage of subjects with normal feet increased in the BFGr and that with flat feet increased in SGr. Barefoot running training causes effects, mainly after an adaptation period of eight weeks, tending to a harmonic surface increase on the support plantar area, with a relative decrease of the midfoot area, which meant a decrease of subjects with plantar arch of flat type.

ABSTRACT

Forefoot disorders are often seen in clinical practice. Forefoot deformity and pain can deteriorate gait function and decrease quality of life. This review presents common forefoot disorders and conservative treatment using an insole or orthosis. Metatarsalgia is a painful foot condition affecting the metatarsal (MT) region of the foot. A MT pad, MT bar, or forefoot cushion can be used to alleviate MT pain. Hallux valgus is a deformity characterized by medial deviation of the first MT and lateral deviation of the hallux. A toe spreader, valgus splint, and bunion shield are commonly applied to patients with hallux valgus. Hallux limitus and hallux rigidus refer to painful limitations of dorsiflexion of the first metatarsophalangeal joint. A kinetic wedge foot orthosis or rocker sole can help relieve symptoms from hallux limitus or rigidus. Hammer, claw, and mallet toes are sagittal plane deformities of the lesser toes. Toe sleeve or padding can be applied over high-pressure areas in the proximal or distal interphalangeal joints or under the MT heads. An MT off-loading insole can also be used to alleviate symptoms following lesser toe deformities. Morton's neuroma is a benign neuroma of an intermetatarsal plantar nerve that leads to a painful condition affecting the MT area. The MT bar, the plantar pad, or a more cushioned insole would be useful. In addition, patients with any of the above various forefoot disorders should avoid tight-fitting or high-heeled shoes. Applying an insole or orthosis and wearing proper shoes can be beneficial for managing forefoot disorders.

ABSTRACT

Skin diseases associated with athletic activities can be classified as skin infections, inflammatory reactions, trauma, and abnormal proliferation, depending on the cause of the condition. Athlete's nodule is a generic term for reactive nodules that occur in athletes. It is particularly common in the foot due to tight sneakers, repetitive pressure or friction, and inappropriate choice of shoes or other sports equipment. The diagnosis of black heel (calcaneal petechiae) should be considered when numerous black spots occur on the soles in patients who frequently engage in abrupt movements, such as starts, stops, or leaps. Palmoplantar eccrine hidradenitis may occur in athletes who play baseball, dance, and climb, activities in which repetitive and strong stimuli are applied to the floor of the hands and feet. Painful fat herniation should be suspected in cases of painful skin-colored firm nodules on the feet of athletes who place a large amount of weight on their feet when moving. Itching, urticaria, angioedema, chest tightness, and syncope occurring within 5 minutes after starting exercise should be suspected to be exercise-induced angioedema/anaphylaxis. Excessive force can cause deformation of nails, as in tennis toe and jogger's toenail. For the diagnosis and treatment of sports-related skin diseases, it is essential to pay attention to patients' hobbies and exercise habits, including sports, and to consider the relationship of those habits with the presumed mechanisms of the skin disease. In addition, thorough pre-exercise warm-ups, increasing strength gradually, and wearing proper equipment will help prevent the occurrence of sports-related skin diseases.

ABSTRACT

BACKGROUND: This study aimed to investigate the effects of critical thinking and good communication skills on the problem-solving abilities of dental hygiene students. METHODS: A total of 508 dental hygiene students were convenience-sampled from 3 universities. RESULTS: The results revealed that critical thinking had the highest intellectual fairness score of 3.60, and systematicity was the lowest at 3.19. The values for communication skills were high in reaction, social adequacy, and concentration, with an average of 3.65. Problem-solving abilities were in the following order: clarification of the problem, seeking solutions, and decision making. According to general characteristics, more extroverted personalities possessed higher levels of critical thinking, communication skills, and problem-solving abilities (p<0.01). Critical thinking scores were high (p=0.016) in students who responded that peer relationship was difficult; however, their communication skills were the lowest (p<0.001). Additionally, problem-solving abilities were highest among students who reported a difficult peer relationship (p=0.001). The higher the satisfaction with dental hygiene academics, the higher the critical thinking, communication skill, and problem-solving ability (p<0.001). Critical thinking showed a high positive correlation with variables in the following order: clarification of the problem, performing the solutions, seeking solutions, decision making, and evaluation and reflection. The communication skills were also related to these variables listed above (p<0.01). With critical thinking, confidence, watchfulness, intellectual passion/curiosity, sound skepticism, objectivity, and systematicity all influenced the problem-solving ability. CONCLUSION: Communication skills were influenced by noise control, putting on the other's shoe, social tensions, and efficiency, which affected the problem-solving ability. Dental clinics require dental hygienists to have critical thinking to make analytical judgments and effective communication skills to solve human relation problems with patients and care-givers. Therefore, these skills should be developed in dental hygiene students to improve their problem-solving abilities.

ABSTRACT

BACKGROUND: Traditionally, conservative management with an offloading orthosis, such as total contact cast (TCC), has been the standard of care for midfoot Charcot arthropathy. Considering complications of TCC and surgery, we treated midfoot Charcot arthropathy without TCC in our patients. The purpose of this study was to report clinical and radiological outcomes of conservative management of midfoot Charcot arthropathy. METHODS: A total of 34 patients (38 feet) who were diagnosed as having midfoot Charcot arthropathy between 2006 and 2014 were included. Patients started full weight bearing ambulation in a hard-soled shoe immediately after diagnosis. Outcomes such as progression of arch collapse, bony prominence, ulcer occurrence, limb amputation, and changes in Charcot stage were evaluated. RESULTS: Of 38 feet, arch collapse was observed in four while progression of bottom bump of the midfoot was observed in five feet. Foot ulcers related to bony bumps were found in two feet. CONCLUSIONS: Conservative treatment without restriction of ambulation is recommended for midfoot Charcot arthropathy because it is rarely progressive, unlike hindfoot-ankle arthropathy. In some cases, simple bumpectomy can be required to prevent catastrophic infection.

ABSTRACT

Abstract: Background: In our country, the Brazilian Standard Series is the most used for the etiological diagnosis of allergic contact dermatitis to shoes. However, there is no assessment of the usefulness of specific allergens for shoes. Objectives: To measure the improvement in diagnostic accuracy of allergic contact dermatitis to shoes with the use of a specific complementary series in patch testing and describe the characteristics of the affected population, such as gender, location of lesions, time of evolution, and the most common allergens. Methods: This retrospective study evaluated the results of 52 patients with suspected shoe dermatitis subjected to patch tests with the standard and specific series to quantify the gain in diagnostic accuracy. Results: Among the 52 suspected cases, 29 cases (56%) were confirmed. In 13 (45%) cases the diagnosis was determined through the specific series, which results in an 81% increase in the number of diagnoses. Study limitation: Small sample size. Conclusions: Women were more commonly affected, with a mean time for the final diagnosis of 45 months, and the most common localization was the dorsum of the feet. There was an increase in diagnostic accuracy with the introduction of new haptens in the patch test of patients with suspected shoes dermatitis.

ABSTRACT

SUMMARY Many women have worn high-heel shoes (HHS) at some point in their lives and many wear them on a daily basis, with higher prevalence between 39% and 78% observed in institutional and clinical settings. The purpose of this study was to describe and compare the scores obtained with regard to foot health and health in general in a sample of women that use HHS as opposed to a sample of women without HHS with normalized reference values. A sample of 120 participants with a mean age of 41.94 ± 13.912 came to a health center where self-reported data were registered. The subjects with and without HHS were determined and the scores obtained were compared in the Foot Health Status Questionnaire (FHSQ). This questionnaire is made of 13 questions that assess 4 health domains of the feet, namely pain, function, general health and footwear. The women in the HHS group showed a worse quality of life related to health in general and to foot health specifically. Differences between the two groups were evaluated by means of a t-test for independent samples, showing statistical significance (P<0.01). Women with HHS present a negative impact on the quality of life related to foot health.


RESUMO Muitas mulheres usaram sapatos de salto alto (SSA) em algum momento de suas vidas e muitas usam diariamente, com maior prevalência entre 39% e 78%, observadas em contextos institucionais e clínicos. O objetivo deste estudo foi descrever e comparar os escores obtidos em relação à saúde dos pés e à saúde em geral em uma amostra de mulheres que utilizam SSA em oposição a uma amostra de mulheres sem SSA com valores de referência normalizados. Uma amostra de 120 participantes com idade média de 41,94 ± 13,912 chegou a um centro de saúde onde os dados autorrelatados foram registrados, os informantes com e sem SSA foram determinados e os escores obtidos foram comparados no Foot Health Status Questionnaire (FHSQ). Esse documento tem 13 questões que avaliam quatro domínios de saúde dos pés, nomeadamente dor, função, saúde geral e calçado. As mulheres do grupo SSA apresentaram pior qualidade de vida relacionada à saúde em geral e à saúde dos pés, especificamente. As diferenças entre os dois grupos foram avaliadas por meio de um teste t para amostras independentes, mostrando significância estatística (P <0,01). As mulheres com SSA apresentam um impacto negativo na qualidade de vida relacionada à saúde dos pés.

ABSTRACT

As the aging of the foot progresses, the stiffness of the soft tissues, the reduction of the range of motion, the decrease of the muscle strength, and the flattening of foot are manifested. These changes increase the risk of foot pain, the problem of weight distribution and transmission, and the risk of falls, resulting in secondary complications and lowering quality of life. The most common deformities and diseases of the elderly foot are hallux valgus, hammertoes, hallux rigidus, Achilles tendinitis, plantar fasciitis, metatarsalgia, hyperkeratosis, and other deformities of the feet caused by chronic conditions. Systemic diseases that promote these foot problems include diabetes, peripheral nerve damage, repetitive ankle ligament injuries, deformities due to fractures, and obesity. Understanding the mechanisms of aging and the processing of biomechanics in the elderly will enable them to reach a healthy life through appropriate rehabilitation, exercise and educations during aging. In addition, it is necessary to promote the healthy life in elderly by customized exercise, training, and shoes.

ABSTRACT

BACKGROUND: Increasing the slip resistance of floor surfaces would be desirable, but there is a lack of evidence on whether traction properties are linearly correlated with the topographic features of the floor surfaces or what scales of surface roughness are required to effectively control the slipperiness of floors. OBJECTIVE: This study expands on earlier findings on the effects of floor surface finishes against slip resistance performance and determines the operative ranges of floor surface roughness for optimal slip resistance controls under different risk levels of walking environments. METHODS: Dynamic friction tests were conducted among three shoes and nine floor specimens under wet and oily environments and compared with a soapy environment. RESULTS: The test results showed the significant effects of floor surface roughness on slip resistance performance against all the lubricated environments. Compared with the floor-type effect, the shoe-type effect on slip resistance performance was insignificant against the highly polluted environments. The study outcomes also indicated that the oily environment required rougher surface finishes than the wet and soapy ones in their lower boundary ranges of floor surface roughness. CONCLUSION: The results of this study with previous findings confirm that floor surface finishes require different levels of surface coarseness for different types of environmental conditions to effectively manage slippery walking environments. Collected data on operative ranges of floor surface roughness seem to be a valuable tool to develop practical design information and standards for floor surface finishes to efficiently prevent pedestrian fall incidents.

ABSTRACT

Background: During pregnancy, a number of changes affecting venous blood flow occur in the circulatory system, such as reduced vein wall tension or increased exposure to collagen fibers. These factors may cause blood stagnation, swelling of the legs, or endothelial damage and consequently lead to development of venous disease. Objectives: The aim of this study is to evaluate the effect of special footwear designed to improve blood circulation in the feet on venous blood flow changes observed during advancing phases of pregnancy. Methods: Thirty healthy pregnant women participated in this study at 25, 30, and 35 weeks of gestation. Participants were allocated at random to an experimental group (n = 15) which was provided with the special footwear, or a control group (n = 15). At each data collection session, Doppler measurements of peak systolic blood flow velocity and cross-sectional area of the right popliteal vein were performed using a MySonoU6 ultrasound machine with a linear transducer (Samsung Medison). The differences were compared using Cohen's d test to calculate effect size. Results: With advancing phases of pregnancy, peak systolic velocity in the popliteal vein decreased significantly in the control group, whereas it increased significantly in the experimental group. No significant change in cross-sectional area was observed in any of the groups. Conclusions: Findings in the experimental group demonstrated that wearing the footwear tested may prevent venous blood velocity from reducing during advanced phases of pregnancy. Nevertheless, there is a need for further investigation of the beneficial effect on venous flow of the footwear tested and its application


Contexto: Durante a gravidez, uma série de mudanças que afetam o fluxo venoso ocorrem no sistema circulatório, tais como menor tensão da parede venosa ou aumento da exposição a fibras de colágeno. Esses fatores podem causar estagnação sanguínea, inchaço das pernas ou dano endotelial e, consequentemente, levar ao desenvolvimento de doença venosa. Objetivos: O objetivo deste estudo foi avaliar o efeito do uso de calçados especiais projetados para melhorar a circulação sanguínea dos pés sobre as mudanças no fluxo venoso observadas nas fases avançadas da gravidez. Métodos: Trinta gestantes saudáveis participaram deste estudo às 25, 30 e 35 semanas de gestação. As participantes foram aleatoriamente designadas a um grupo experimental (n = 15) que recebeu calçados especiais, ou um grupo controle (n = 15). A cada sessão de coleta de dados, foram obtidas medidas Doppler do pico de velocidade do fluxo sanguíneo sistólico e da área transversal da veia poplítea direita, utilizando-se um aparelho de ultrassom MySonoU6 com transdutor linear (Samsung Medison). As diferenças foram comparadas utilizando-se o teste d de Cohen para calcular o tamanho do efeito. Resultados: Nas fases avançadas da gravidez, o pico da velocidade sistólica na veia poplítea diminuiu significativamente no grupo controle, porém aumentou significativamente no grupo experimental. Não houve mudanças significativas na área transversal da veia poplítea em nenhum dos grupos. Conclusões: Os achados do grupo experimental demonstraram que o uso dos calçados especiais testados pode evitar que a velocidade do fluxo venoso diminua nas fases avançadas da gravidez. No entanto, mais estudos são necessários para investigar os efeitos benéficos sobre o fluxo venoso do uso dos calçados testados e suas aplicações

ABSTRACT

ABSTRACT Objective: to understand the experience of care of people with venous ulcers using an Unna's boot. Method: a qualitative study, based on the social phenomenology by Alfred Schütz, was carried out with 12 adults interviewed in 2015. The statements were analyzed and organized in thematic categories. Results: the following categories emerged: "Unna's boot annoyance versus wound improvement", "Difficulties for accessing care with the Unna's boot", "Care for healing and preventing recurrence", and "Receiving more attention from the healthcare professional". Conclusion: the experience of care of people using an Unna's boot revealed the annoyance caused by this device, which was overcome due to the wound improvement. However, access to care was compromised by the lack of structure at the service, frustrating the patients' expectations regarding wound healing. The issues of these people's intersubjective universe should be considered in the management of care of venous ulcers.

ABSTRACT

In this work, we develop a device, called ‘Walk-Even’, that can provide real-time feedback to correct gait asymmetry commonly exhibited in post-stroke survivors and persons with certain neurological disorders. The device computes gait parameters, including gait time, swing time, and stance time of each leg, to detect gait asymmetry and provide corresponding real-time biofeedback by means of auditory and electrotactile stimulation to actively correct the user's gait. The system consists of customized force-sensor-embedded insoles adjustable to fit any shoe size, electrotactile and auditory feedback circuits, microcontroller, and wireless XBee transceivers. The device also offers data saving capability. To validate its accuracy and reliability, we compared the gait measurements from our device with a commercial gait and balance assessment device, Zeno Walkway. The results show good correlation and agreement in a validity study with six healthy subjects and reliability study with seventeen healthy subjects. In addition, preliminary testing on six post-stroke patients after an 8-week training shows that the Walk-Even device helps to improve gait symmetry, foot pressure and forefoot loading of the affected side. Thus, initial testing indicates that the device is accurate in measuring the gait parameters and effective in improving gait symmetry using real-time feedback. The device is portable and low cost and has the potential for use in a non-clinical setting for patients that can walk independently without assistance. A more extensive testing with stroke patients is still ongoing.

ABSTRACT

The present study was performed to reveal the current status and risk factors of Strongyloides stercoralis infections in the villages of Kenethao district, Xayaburi Province, Lao PDR. Fecal specimens were collected and examined for S. stercoralis using Koga-agar plate culture technique. Among 516 individuals, the prevalence of S. stercoralis and hookworm infection was 44.2% and 17.1%, respectively. Co-infection was detected in 13.2% of the cases. The prevalence did not significantly differ between males and females (P=0.193). However, the prevalence of S. stercoralis infection increased significantly with age (P=0.041). Of the risk factors examined, both performing farming activities (P=0.001) and walking barefoot when going outside of the house (P=0.003) showed significant correlations with S. stercoralis infections. Our results suggest that S. stercoralis is highly endemic in this area. The National Helminth Control Program of Lao PDR should take actions to control S. stercoralis infection. In addition, provision of health education about the benefits of wearing shoes would be important for reducing infection in the study area. Moreover, the application of high-sensitivity diagnostic approaches is needed to obtain the true impact of S. stercoralis infections in all rural communities in order to provide surveillance activities in Lao PDR.

ABSTRACT

PURPOSE: The purpose of this study was to explore the predictors of turnover intention among nurses working in small and medium-sized hospitals in South Korea. METHODS: Data were obtained from a survey conducted in 2016 on welfare policy and system improvement. The participants were nurses of the Korean Nurses Association who worked in small and medium-sized hospitals. The responses of 2,011 nurses were analyzed using hierarchical multiple regression analysis, which was performed to explore the predictors of nurses' turnover intentions. RESULTS: The findings of this study showed that the predictors significantly reducing nurses' desire to leave their hospitals were a 40-hour workweek, satisfaction with the salary, and six out of the 40 fringe benefits provided by their hospitals: the provision of uniforms and work shoes, paid menstrual leave, operational costs for the department, job-related educational costs, and in-house nurse training program. CONCLUSION: These findings suggest that hospitals should provide proper work hours and reasonable rewards for nurses' work in order to reduce turnover intention among their nurses.

ABSTRACT

The purpose of this study was to identity the probability of cross-contamination from the environment. For this, we examined foodservices at 20 universities/colleges for microbiological analysis of their working facilities and environment as well as their preventive equipment against cross-contamination. Seventy percent of the 20 foodservices were found to maintain one unified working area, which suggests high probability of contamination of food/utensils/equipment in the cooking area by pre-preparation or dish washing. According to the microbiological analysis, the hygiene acceptance ratio of working facilities in the clean zone was 70%, which was higher than the average 45% hygiene acceptance ratio of working facilities in the contamination operating zone. There was a significant difference in the total plate count (P<0.001) and coliform count (P <0.01), which demonstrates that work tables in the clean zone were in a good state compared to those in the contamination operating zone. In the contamination operating zone, refrigerator shelves had a high probability of cross-contamination. Regarding the floor surface and airborne microbes, cooking areas which should be maintained as clean zones had higher cross-contamination probability than those in the contamination operating zone. So corrective actions such as cleaning and sanitizing, keeping dry floors, lowered temperature and humidity, shoe disinfecting facilities, and checking concentrations, are necessary to manage floor surfaces and airborne microbes in the cooking area.

ABSTRACT

Summary Introduction: The use of an improper shoe size is common in older people and is believed to have a detrimental effect on the quality of life related to foot health. The objective is to describe and compare, in a sample of participants, the impact of shoes that fit properly or improperly, as well as analyze the scores related to foot health and health overall. Method: A sample of 64 participants, with a mean age of 75.3±7.9 years, attended an outpatient center where self-report data was recorded, the measurements of the size of the feet and footwear were determined and the scores compared between the group that wears the correct size of shoes and another group of individuals who do not wear the correct size of shoes, using the Spanish version of the Foot Health Status Questionnaire. Results: The group wearing an improper shoe size showed poorer quality of life regarding overall health and specifically foot health. Differences between groups were evaluated using a t-test for independent samples resulting statistically significant (p<0.05) for the dimension of pain, function, footwear, overall foot health, and social function. Conclusion: Inadequate shoe size has a significant negative impact on quality of life related to foot health. The degree of negative impact seems to be associated with age, sex, and body mass index (BMI).


Resumo Introdução: o uso de sapatos com tamanhos inadequados é comum em pessoas idosas e acredita-se resultar em efeito negativo sobre a qualidade de vida relacionada à saúde do pé. O objetivo é descrever e comparar o impacto de uma amostra de participantes usando calçados de tamanho adequado e indivíduos com calçados de tamanho inadequado, e as pontuações relacionadas com a saúde do pé e geral. Método: de uma amostra de 64 participantes, com idade média de 75,3±7,9, de um centro ambulatorial, dados de autorrelato foram registrados e medidas do tamanho dos pés e dos calçados foram determinadas. Os escores foram comparados pelo Foot Health Status Questionnaire, na versão em espanhol, entre os grupos que usavam sapatos de tamanhos corretos e incorretos. Resultados: o grupo que utilizava sapatos inadequados mostrou pior qualidade de vida relacionada à saúde geral e no pé. Diferenças entre os grupos foram avaliadas utilizando o teste t para amostras independentes, sendo estatisticamente significativas (p<0,05) para dimensão da dor, função, calçados, saúde geral, do pé e função social. Conclusão: o uso de calçado inadequado tem um impacto negativo significativo sobre a qualidade de vida relacionada à saúde do pé. O grau de impacto negativo parece estar associado com idade, sexo e índice de massa corpórea (IMC).

ABSTRACT

Most children and adolescents with flexible flatfeet are asymptomatic and most do not require treatment. Scant convincing evidence exists to support the use of inserts or shoe modifications for effective relief of symptoms, and there is no evidence that those devices change the shape of the foot. Surgical correction is indicated for failure of prolonged nonsurgical attempts to relieve pain that interferes with normal activities and occurs under the medial midfoot and/or in the sinus tarsi. Osteotomies with supplemental soft-tissue procedures or arthroereisis are the suggested operative procedures for symptomatic flatfoot. An associated contracture of the heel cord is present in nearly all cases. Concurrent rigid forefoot supination deformity should be addressed as well.
