Resumo:

A case of congenital cleft foot deformity, also known as lobster claw or split foot, is presented. The condition is rare. A review of the literature reveals that this deformity will often coexist as part of a constellation of congenital and familial abnormalities. Surgical correction of the cleft foot is difficult and often deferred.

Resumo:

The aim of this study was to determine the pre- and post-plantar force differences of athletes competing in an ultra-endurance event. The study was exploratory and quasi-experimental in nature and utilized a quantitative approach. A Quasi-experimental, one group pretest, posttest design was used. The study involved 84 participants selected by means of convenient sampling from a total of 1552 participants. The equipment used for data collection was the RS Footscan®, stadiometer and a weight scale. Differences between the plantar forces before and after the competition were significant for the sample group, indicating higher forces before the competition (t = -3.62, p = 0.001, d = 0.40). Gender, and novice and expert groupings had no significant effect on the plantar forces (t = 1.43, p = 0.155 and t = 0.21, p = 0.837) respectively. Gender groups had large significant differences between the left and right forefoot (t = 3.90, p = 0.000) and the heel (t = 3.54, p = 0.001), before the competition, but this difference was reduced after the competition from large to moderate significance for the forefoot and the heel (t = 2.84, p = 0.006 and t = 2.99 and p = 0.004) respectively. Lower forces after the ultra-endurance event may indicate compensation due to overuse; with less muscle contraction to control foot roll over for force distribution. Favouring of the right foot for weight bearing changed after the event with smaller differences, which could indicate increase loading of the left feet, which may result in injury. The number of females included in this study was relatively few and therefore the effect of gender in respect of plantar foot force exerted should be interpreted with caution. The novices recorded higher forces in the forefoot, after the competition. Similar results were found in other studies that reported increased pressures under the forefoot after long distance running. The latter findings may suggest that novices have a higher chance for overuse injury.

Resumo:

Diabetes can affect the structure and function of the foot, resulting in severe limitation of mobility and reduction of life expectancy. Early warning signs include limited joint mobility (LJM), soft tissue changes, high plantar pressure (HPP), high pressure time integrals (P/TI) and plantar callus. These abnormalities were examined in 216 young people with diabetes and 57 controls. The fingers, toes, ankle subtalar and first metatarsophalangeal joints shows reduced motion and the plantar aponeurosis was thicker in diabetic subjects. Skin thickness was the same for diabetic and control subjects. LJM in the feet was more common in males and older subjects. Subtalar and finger LJM was associated with early sensory nerve changes and finger LJM was associated with retinopathy and higher HbAtc. Thicker plantar aponeurosis was associated with male gander and larger feet. High peak pressure, high P/TI and callus were no more common in diabetic subjects than controls. However, high P/TI and callus were associated with early sensory nerve changes in young people with diabetes. Diabetic subjects with callus were significantly older than those without callus. Those with HPP had higher body mass index and less motion at the first MTP joints than those without HPP. Although plantar callus, HPP and high P/TI were no more common in young people with diabetes these abnormailities may be complicated by diabetes. Cushioning, custom orthoses or both in combination significantly reduced peak pressure and P/TI in diabetic subjects.

Resumo:

Obesity prevalence is higher in Down syndrome (DS) than in the general population. Beyond metabolic alterations, individuals with DS present increased impulsivity, a trait observed in obese people and in compulsive eaters that may affect their control of food intake. In this Thesis, we used a trisomic DS mouse model (Ts65Dn) to understand the behavioral component of obesity in DS and explore some possible underlying mechanisms. Our meal pattern analysis revealed longer and slowly meals in Ts65Dn mice, leading to reduced eating rate, which may be associated to the mandible hypoplasia described in both human and mice. When exposed to obesogenic environments, Ts65Dn mice showed higher preference for energy-dense food, gained more weight in specific conditions and scored higher in compulsivity and inflexibility tests than WT mice, as measured by binge eating during limited access and persistence of consumption of quine adulteration of energy-dense food. High performance liquid chromatography revealed reduced levels of dopamine in prefrontal cortex in Ts65Dn mice. This could lead to higher reward sensitivity that in turn would facilitate overeating as a compensatory response to restore optimal dopamine levels. Feeding behavior is also regulated by hormones and other circulating signals. We detected higher plasma leptin and glucose levels along with reduced insulin levels in Ts65Dn mice. Upon a glucose challenge, Ts65Dn mice showed reduced glucose-stimulated insulin response both in vivo and in vitro, suggesting a deficient insulin secretion or the reduced pancreatic mass. Indeed, we detected that Ts65Dn mice had altered plasma profile for some markers of inflammation and oxidative damage, in agreement with the high prevalence of autoimmune diseases and diabetes in DS people. We also explored the involvement of the serine/threonine kinase DYRK1A, a candidate DS gene, in obesity and feeding behavior. Dyrk1A overexpression was sufficient to recapitulate some behavioral aspects associated to overeating in DS, but with a distinct profile. We conclude that increased obesity prevalence in DS is explained by both metabolic and behavioral alterations, in part driven by a hypodopaminergic status, and that Dyrk1A overexpression is only involved in specific DS obesity phenotypes.
La prevalencia de obesidad es más alta en el síndrome de Down (SD) que en la población general. Más allá de las alteraciones metabólicas, los individuos con SD tienen mayor impulsividad, rasgo común en personas obesas y en comedores compulsivos, que pueden afectar el control de la ingesta de alimentos. En esta Tesis, se ha utilizado un modelo de ratón trisómico (Ts65Dn) para comprender el componente de comportamiento en el desarrollo de la obesidad en SD. Nuestro análisis del patrón de ingesta mostró que los ratones Ts65Dn comen más lento que los euploides, lo que podría estar asociado con la hipoplasia mandibular descrita en ratones y humanos con SD. Cuando los ratones Ts65Dn son expuestos a ambientes obesogénicos, comen mayores cantidades de dietas hipercalóricas, engordan más en determinadas condiciones y puntúan más alto en pruebas de compulsividad e inflexibilidad que los ratones euploides. La cuantificación de los niveles de monoaminas mediante cromatografía líquida reveló que los ratones Ts65Dn presentan niveles más bajos de dopamina en corteza prefrontal. Dado que las dietas hipercalóricas promueven la liberación del neurotransmisor en el circuito de recompensa, el sobre consumo de las mismas podría indicar un intento de restaurar los niveles óptimos de dopamina. La regulación de la ingesta también depende de otras señales circulantes. Detectamos que los ratones Ts65Dn tienen mayores niveles de leptina y glucosa en plasma y niveles más bajos de insulina que los euploides. La administración exógena de glucosa produjo una menor respuesta secretoria de insulina en los ratones Ts65Dn in vivo e in vitro. Además, diversos marcadores de inflamación y estrés oxidativo son más elevados en los ratones Ts65Dn, en consonancia con la mayor incidencia de enfermedades autoinmunes y diabetes en personas con SD. En esta Tesis también se ha explorado la contribución de la proteína serina / treonina quinasa DYRK1A, un gen candidato para SD en la obesidad e ingesta. La sobreexpresión de Dyrk1A es suficiente para recapitular algunos comportamientos asociados a la ingesta compulsiva, pero con un perfil distinto al observado en el modelo trisómico. Concluimos que la prevalencia de la obesidad en SD se explica por alteraciones tanto metabólicas como conductuales, en parte como consecuencia de un estado de hipodopaminergia, y que la sobreexpresión de Dyrk1A está implicada en fenotipos específicos de la obesidad en SD.

Resumo: O objetivo deste trabalho foi avaliar a precisão do posicionamento maxilar em cirurgias ortognáticas bimaxilares utilizando sequência cirúrgica convencional e sequência invertida, isto é, quando a mandíbula foi osteotomizada e fixada antes da maxila. Neste estudo retrospectivo, 80 telerradiografias obtidas em norma lateral de pacientes submeditos à cirurgia ortognática foram analisadas, sendo 40 obtidas no período pré-operatório e 40 no pós-operatório. A amostra foi dividida em 2 grupos de acordo com a sequência cirúrgica executada. No Grupo 1 constaram as radiografias de pacientes submetidos à cirurgia através da sequência convencional, enquanto no grupo 2 constaram as radiografias dos pacientes submetidos à cirurgia pela sequência invertida. Em ambos os grupos foi analisada posição final do incisivo central superior, tanto no sentido vertical quanto no ântero-posterior, sendo este resultado comparado com o que fora planejado, na busca da precisão cirúrgica. O resultado encontrado nos grupos 1 e 2 foram então confrontados na busca de diferenças entre as duas técnicas. Foi testada a hipótese nula de que não havia diferença entre os grupos analisados. Após aplicado o teste t de Welch para comparação das médias das diferenças entre o desejado e o obtido nos grupos 1 e 2, considerando significância estatística de 5% (alpha) e um teste bi-caudal, chegou-se a evidência estatística de que a hipótese não nula foi rejeitada dados os resultados obtidos das amostras (p>0,05). Sendo assim, não houve diferença no grau de precisão do posicionamento maxilar entre os grupos. Concluiu-se que tanto a sequência cirúrgica convencional quanto a sequência cirúrgica invertida mostraram ser técnicas confiáveis no posicionamento maxilar após osteotomia. tipo Le Fort I
Abstract: The objective of this study was to evaluate maxillary positioning accuracy of double jaw orthognathic surgery using conventional surgical sequence and inverted sequencing, ie, when the mandible was osteotomized and fixed prior to the jaw. In this retrospective study, 80 lateral radiographs obtained in patients that underwent orthognathic surgery were analyzed, 40 obtained in the preoperative and 40 in the postoperative period. The sample was divided into two groups according to the surgical sequence performed. Group 1 consisted of the radiographs of patients submitted to conventional surgical sequence, while group 2 consisted of the radiographs of patients that underwent surgery by the inverted sequencing. In both groups the final position of the maxillary central incisor was analyzed (in the vertical and anteroposterior planes), and this result was compared with what was planned in the pursuit of surgical precision. The results found in groups 1 and 2 were then compared in the search of differences between the two techniques. The null hypothesis, which stated that there was no difference between the groups, was tested. After applying the Welch t test for comparison of mean differences between the desired and obtained in groups 1 and 2, considering a statistical significance of 5% (alpha) and a two-tailed test, the null hypothesis was not rejected given the results of the samples (p> 0.05). Thus, there was no difference in the accuracy of maxillary positioning between the groups. It was concluded that the conventional surgical sequence as well as the inverted sequencing proved to be reliable in positioning the maxilla after Le Fort I osteotomy

Resumo:

Craniofaciossinostose sindrômica (CS) é uma desordem congênita associada às mutações dos genes FGFR1, FGFR2 e FGFR3. Ocasiona uma fusão prematura das suturas craniofaciais, levando à deficiência no crescimento do crânio e terço médio da face. A severidade dos sintomas relacionados à hipertensão intracraniana, aparelho respiratório (síndrome da hipopneia-apneia do sono) e ocular (órbitas rasas, proptose ocular, exorbitismo e falta de proteção do globo ocular), são parâmetros para indicar o procedimento cirúrgico. A tomografia-3D é uma opção atual e pouco utilizada para avaliar os volumes orbitais e a magnitude dos avanços craniofaciais e seus vetores; esse método permite melhor definição das estruturas anatômicas sem distorção das imagens, promovendo uma avaliação adequada dos resultados. Os objetivos do presente estudo foram avaliar os volumes orbitais, os avanços craniofaciais e seus vetores nas osteotomias Le Fort III e Monobloco com uso de aparelhos distratores, a correlação entre os avanços craniofaciais e a variação dos volumes orbitais e determinar a eficácia dos avanços craniofaciais por meio da comparação com índices normais de volumes orbitais. No período de janeiro de 2001 a dezembro de 2012, foram selecionados 20 pacientes submetidos ao alongamento ósseo gradual do terço médio da face, divididos em dois grupos. Grupo LF (n = 9), submetidos à osteotomia Le Fort III e Grupo MB (n = 11), submetidos à osteotomia frontofacial monobloco. A avaliação constou da revisão de prontuários e exames tomográficos, em que foram mensurados o volume orbital pela segmentação de imagens no programa InVesalius e modelagem 3D no programa Magics, e a magnitude dos avanços craniofaciais, e seus vetores, foram medidos no programa Rhinoceros. Os resultados foram submetidos à análise estatística: teste t- Student e ANOVA. No Grupo MB, houve aumento de 8,94 mm3 e 9,84 mm3 para a variação do volume orbital, nas órbitas direita e esquerda, respectivamente; no Grupo LF: 5,70 mm3 e 5,77 mm3, respectivamente, para esses parâmetros. A resultante do avanço médio, para a órbita direita e esquerda no Grupo LF foi 11,36 ± 3,80 mm e 11,11 ± 3,45 mm, respectivamente; já no Grupo MB, foi 14,22 ± 4,12 mm e 14,48 ± 4,49 mm, respectivamente. A correlação entre a resultante do avanço e a variação dos volumes orbitais foi significante no Grupo LF e para a órbita esquerda no Grupo MB. Em conclusão, o procedimento cirúrgico foi eficaz, tanto para o Grupo LF como para o Grupo MB, pois, houve aumento estatisticamente significativo do volume orbital no período pós-operatório; não houve diferença estatisticamente significativa, na avaliação da simetria, entre os volumes orbitais pós-operatórios, direito e esquerdo. Ainda, não houve diferença estatisticamente significante entre os volumes orbitais pósoperatórios quando comparados aos índices de normalidade
Syndromic craniofacial synostosis (CS) is a congenital disorder, which is most often, an autosomal dominant mutation associated to FGFR1, FGFR2 and FGFR3 genes. It causes a premature fusion of craniofacial sutures, leading to deficiency in skull growth and middle-third of the face. The severity of the intracranial hypertension related, respiratory syndrome (hypopneaapnea) and eye (shallow orbits, ocular proptosis, exorbitism and lack of protection of the eyeball) symptoms, are parameters that indicate the surgical procedure. Distraction osteogenesis of the middle-third of the face is currently the chosen technique for the treatment of patients with Craniofacial Synostosis syndrome candidates for the advancement of the middle-third of the face. The 3D-tomography is a current option and seldom used for this purpose; this method allows better definition of anatomical structures without image distortion, providing a more accurate assessment of the results. The objectives of the present study, were to assess quantitatively the craniofacial advancement and its vectors through 3D tomographic images, the osteotomy Le Fort III and Monobloc with use of distractor devices; Also, to evaluate the correlation between the craniofacial advances and the variation of orbital volumes and determine the effectiveness of craniofacial advances through the comparison with normal levels of orbital volumes. From January 2001 to December 2012, 20 patients underwent distraction osteogenesis of the middle-third of the face, divided into two groups. LF group (n = 9) underwent a Le Fort III osteotomy and MB group (n = 11) underwent a monobloc frontalfacial osteotomy. The evaluation consisted of the reviewing of the records and tomographic exams; measured is the orbital volume by image segmentation on the InVesalius software and 3D modeling on Magics software and the magnitude of facial advances, and their vectors, were measured on Rhinoceros software. The results were subject to statistical analysis: t-Student test and ANOVA. In the MB group, there was an increase of 8.94 mm3 and 9.84 mm3 for the variation of the orbital volume, the right and left orbits, respectively; in Group LF: 5.70 mm3 and 5.77 mm3 for these parameters. The resulting of average advance, for right and left orbit in Group LF was of 11.36 ± 3.80 mm, 11.11 ± 3.45mm, respectively; as for group MB it was 14.22 ± 4.12 mm and 14.48 ± 4.49 mm, respectively. Correlation between the results from the progress and the variation of orbital volume was significant in Group LF and left orbit in MB Group. In conclusion, the surgical procedure was effective for both the LF group as for the MB Group because: there was a statistically significant increase in orbital volume on the postoperative period; there was no statistically significant difference in the evaluation of symmetry between the postoperative period left and right orbital volumes. Still, there was no statistically significant difference between the postoperative orbital volumes when compared to normal ranges

Resumo:

INTRODUÇÃO: A osteotomia em monobloco para o avanço do terço médio e superior da face combinada ao alongamento ósseo gradual consiste em uma modalidade consagrada de tratamento das craniossinostoses sindrômicas. No entanto, alguns aspectos referentes à morfologia do terço médio facial dessas condições, seu comportamento durante o crescimento e quando submetido à cirurgia ainda são pouco compreendidos. OBJETIVOS: Avaliar, por meio de imagens tomográficas tridimensionais, um grupo de pacientes submetidos ao avanço frontofacial em monobloco associado à distração osteogênica, em idade de imaturidade esquelética, quanto às características morfológicas do terço médio da face, aos resultados obtidos com o avanço e seus efeitos no crescimento craniofacial comparados a um grupo não sindrômico. MÉTODOS: A amostra foi constituída de 25 indivíduos, em idade de dentição mista sendo: 16 submetidos ao avanço com exames de tomografia pré e pós-operatório e 9 de um grupo comparativo não sindrômico com exames de tomografia com 1 ano de intervalo durante o período de crescimento. Pontos de referência foram marcados nos modelos de superfície tridimensional do terço médio facial e as seguintes mensurações foram realizadas para o grupo comparativo, dos pacientes antes e após a cirurgia: determinação das dimensões da maxila, ângulos faciais e distâncias entre pontos na base do crânio e superfície da face. A mensuração das distâncias entre pontos correspondentes marcados nas imagens sobrepostas dos diferentes tempos foi utilizada para determinação da magnitude do avanço e comparada aos valores do grupo não sindrômico. Da mesma forma, o crescimento craniofacial prévio à cirurgia foi avaliado em 4 pacientes da amostra que dispunham de exames de tomografia com 1 ano de intervalo previamente ao avanço. O crescimento pós-operatório foi avaliado em 9 pacientes que tinham exames de tomografia com 1 ano de intervalo após o procedimento e ambos foram comparados com o crescimento observado no grupo não sindrômico. RESULTADOS: A maxila dos pacientes com craniossinostose é menor em largura e comprimento comparada aos não sindrômicos. Os ângulos faciais formados pelos pontos orbitário direito e esquerdo e ponto A, zigomático direito e esquerdo e ponto A são estatisticamente diferentes dos não sindrômicos. As distâncias do ponto Sela aos pontos do terço médio são menores nos pacientes comprometidos mas atingem valores comparáveis aos não sindrômicos após o avanço. O crescimento no grupo de crianças com craniossinostose embora não tenha apresentado valores estatisticamente diferentes dos demais, numericamente cresce menos que o grupo comparativo tanto prévia como posteriormente ao procedimento. CONCLUSÕES: O terço médio facial nas craniossinostoses apresenta configuração anatômica alterada, a maxila é hipoplásica e os ângulos faciais mais obtusos denotam uma menor projeção da porção central em relação às laterais. O avanço permite a normalização da posição, no entanto não muda a configuração alterada do terço médio. O crescimento aparentemente está comprometido independente do procedimento cirúrgico
INTRODUCTION: The monobloc osteotomy combined with gradual bone lengthening to advance the upper and midface is an established treatment modality of syndromic craniosynostosis. However, some aspects related to midface morphology and changes during growth and following surgery are still poorly understood. OBJECTIVES: Three-dimensional tomographic image evaluation of patients undergoing frontofacial monobloc distraction group in immature skeletal age is the objective of the study. The morphological characteristics of the midface, the results obtained with the advancement and its effects on craniofacial growth compared to a nonsyndromic group were evaluated. METHODS: The sample consisted of 25 patients of mixed dentition age: 16 submitted to advancement with pre- and postsurgery CT scans and 9 of a comparison nonsyndromic group with CT scans at 1-year intervals during craniofacial growth. Reference points were placed in the 3-dimensional surface models of the midface, and the measurements were performed to compare patients in the pre- and postsurgery groups: determination of the maxillary dimensions, facial angles, and distances between points on the skull base and the surface of the face. The measurement of distances between homologous points placed in the 3D superimposition of images from different times was used to determine the magnitude of the advancement and compared to the values of the nonsyndromic group. Presurgical growth was evaluated in 4 patients that had a 1-year interval prior to the surgery CT scans. Postsurgical growth was evaluated in 9 patients who had CT scans at 1-year intervals after the procedure, and they were compared with the growth of the nonsyndromic group. RESULTS: The maxillary width and length of syndromic patients are smaller compared to the nonsyndromic group. Facial angles formed by right and left orbital points and point A and the right and left zygomatic and Point A are statistically different from those in the nonsyndromic group. The distances from the point Sela to the midface points are lower in syndromic patients but reach values comparable to the nonsyndromic group after advancement. However, growth in the group of children with craniosynostosis did not yield statistically different values of others; it is smaller than the comparison group. CONCLUSION: The midface of syndromic craniosynostosis has a changed anatomical shape, the maxilla is hypoplastic, and the most obtuse facial angles denote a lower projection of the central portion relative to the lateral. The advancement allows the normalization of the position, but the midface shape is not changed.The growth apparently is affected independently of the surgical procedure

Measurements of sequential Ground Reaction Force (GRF) can provide quite useful information for monitoring of gait abnormalities during activities in daily life. Measuring sequential GRF in conventional approach using force plates is difficult due to the limited number of force plates. Therefore, we developed a fully untethered GRF sensing system having the low height (12 mm) and the capability of sensing simultaneously shear and normal GRF. The biaxial force sensing shoe showed the excellent repeatability (0.6 %) under long-term periodic loading condition for two hours. Comparison experiments with commercially available film type force sensors, FSR (Interlink) and Flexiforce (Tekscan), were performed under walking condition for twenty minutes. Owing to the high repeatability of the proposed system, variabilities of swing time and stance time of user were investigated with two subjects, a healthy subject and a foot-drop patient. We suggested three diagnostic measures in consideration of conventional approaches — variability for gait symmetry, center of pressure distribution for balance, and ratio of shear and normal GRFs for foot pronation.

The viscoelastic cushion insoles respond to the unique curves and pressures of our foot with every movement whether walking, running, playing, or exercising. Initially NASA, USA had developed viscoelastic foam insole to support astronauts during the heavy G force applied to the body during space flight. Nowadays ¼ inch thick layer of viscoelastic foam sandwiched between two layers of different types of foam are available commercially at a high cost. In our country, viscoelastic PU foams as cushion inserts for shoes are imported from China. But the available materials are not scientifically characterized and optimized for the composition of PU for application as an insole for treating foot abnormalities. In this project PU, the viscoelastic foam was prepared using standard polyols and dissociates used by industries to prepare memory foam mattresses. The additives which are physiologically and environmentally safe were used.

The accelerated rate of development of modern technology has greatly expanded the range of health hazards. Lead, a widely used industrial material, is a significant environmental pollutant that contaminates food, water, soil and air. Although much progress has been made in elucidating its adverse effects on various systems of the body like hepatic, CNS, renal etc., its effect on coagulation remains to be established. In view of this an experimental study was carried out in animals to understand how lead influences hemostasis.Male albino rats were exposed to lead either acutely by administering 20 mg lead acetate per kg body weight daily i.p. for 3 days or chronically by administering lead through drinking water containing 5 ppm lead for 150 days. Acute exposure to lead caused severe coagulopathy characterized by significant prolongation of plasma recalcification time, decrease in platelet count and decreased wall adherence of blood, decreased fibrinogen and euglobulin lysis time and significant increase in prothrombin time, thrombin time, and partial thromboplastin time. Similar observations were found in chronically exposed animals. It is concluded that exposure to heavy metals like lead may lead to a state of hypocoagulability.

Ponseti technique is a common non-surgical treatment based on serial manipulation and casting for idiopathic infant clubfoot. We have used three dimensional MRI throughout the treatment, to investigate the effect of the casts on the clubfoot of a one week old (at the beginning of treatment) male with unilateral right idiopathic congenital clubfoot deformity. A total of 21 MRI scans were obtained during weekly serial manipulation and corrective casting. Changes in shape, volume, ossification, and positional relationships of the hind foot anlagen were studied. We found that immediate shape changes occur following casting, particularly in the talus and the navicular, and when after one week the cast is removed the anlagen do not elastically return to their original shape and position prior to casting. Furthermore, the growth rate of some of the clubfoot anlagen, in particular the talus, was faster than normal. A faster ossification was observed in the calcaneus and cuboid. Results also showed correction in parallelism of calcaneus and talus in the anteroposterior plane, minor correction of this parallelism in the lateral view necessitating a heel cord tenotomy, and correction of the medial rotation of calcaneus. Under this treatment changes in talar neck angle yielded a decreasing trend. The navicular moved with respect to the head of the talus from a medial to a lateral position. Relative to the talar body it shifted laterally. Also the geometrical center of talus ossific nucleus was noted to move towards the center of the whole anlagen suggesting that the ossification extends in the opposite direction from the head of the talus. It was concluded that the mechanism of adaptation to the casting loads was quick deformation immediately upon cast application followed by adaptation to the new shape in the cast. These were qualitative findings. It was also concluded that most of the correction occurred during the initial treatment period, primarily during the first and second weeks (1). On the quantitative end, it was confirmed that MRI and computer techniques can be utilized to ascertain and quantify the abnormalities which were impossible to well identify otherwise. MRI based studies have powerful potential to provide helpful information on the choice of treatment as well as guidance throughout. For instance, it may therefore be possible in the present case to shorten the treatment time without adverse effects on the outcome.

Introduction: Identifying factors that contribute to occupational accidents has been a general concern of companies in the present millennium. One of the factors identified is the quality and quantity of food, as well as meals times. In this context, the present systematic review aimed to identify how food intake influences the occurrence of accidents in shift work, with some focus, although not exclusive, on the mining industry. Methodology: The research-based literature was carried out in four electronic databases: Medline/PubMed, Science Direct, Scopus and Web of Science. Have been combined the following words “occupational accident” and “food intake”; “mining injury” and “food choice”; “meal timing” and “workplace”; “eating at night” and “mining injury”;“Circadian rhythm” and “diet shift”; “Food safety” and “ Health risk”; “workplace accidents” and “food choice”. Results: It was possible to identify 24 articles related to food intake. To better understand the analysis, the results were organized into five groups: Author surname and year, Study type, Accidents/injury causes, risk factor, Conditions for accidents/injuries to occur. Through the groups of causes, it was possible to regrouped on three, which facilitated the discussion of the topic; food choice n=10 (42%) articles, eating habits n=9 (37.5%), and emotional commitment n=5 (20.5%), showed the relativity of food intake causes for the occurrence of accidents and illnesses in shift workers. Discussion: The reviewed articles demonstrated that the materialisation of accidents was due to the relationship between food intake and consumption of nutrient-poor foods in shift work. That can develop chronic diseases, metabolic disorders such as blood pressure abnormalities, blood sugar fluctuation (dyslipidemia, dysglycemia), and obesity, neurobehavioural performance. Foods contain high content As, Cd, Cr, Hg, Fe, and Mn above the recommended standards by the FAO/WHO. Sleep disturbance during the 12-hour shift interferes with circadian rhythm and, consequently,with performance. These factors can be related to food and the precarious physical environment, increased workload, fatigue and poor diet, especially at night. Conclusion: In conclusion, the study demonstrated how food intake impacted workers' health on shifts but did not determine the causes or risk factors contributing to accidents/injuries. Further studies are needed to demonstrate a direct relationship which the risk factor of food intake and causes accidents/injuries.

ABSTRACT Background: Toxoplasmosis is a condition in which a person is infected with Toxoplasma gondii. Humanitarian transmission is closely linked to the environment in which they live and the conduct that allows the entry into the body of Oocyst Toxoplasma gondii. Toxoplasmosis in married women is very dangerous because it can cause conditions of infertility, repeated spontaneous abortion, stillbirth, and congenital abnormalities. This study aimed to analyze the association between environmental and behavior on toxoplasmosis incidences among married women. Subjects and Method: This was a case-control study carried out at the Alternative Medical Clinic, Aquatreat Therapy Indonesia Foundation in Bogor City during 2019. Total of 160 women were enrolled in this study and divided into 2 groups: 80 in case group and 80 in control group. The dependent variable was toxoplasmosis behavior. The independent variables were environmental and behavior factors. Data were collected from clinical laboratory results and questionnaire and analyzed using a multiple logistic regression. Results: In environmental factors, presence of pets at home (OR= 3.73; 95%CI= 1.83 to 7.61; p<0.001), presence of wild cats or neighboring cats that are often seen around the house (OR= 2.63; 95%CI= 1.24 to 5.58; p= 0.012), and risky environment (OR= 9.60; 95%CI= 3.74 to 24.61; p<0.001) were significantly associated with toxoplasmosis among married women. In behavior factors, consumption of raw vegetables/vegetables (OR= 4.53; 95%CI= 1.23 to 16.73; p= 0.023), consumption of smoked meat/ steak/ undercooked (OR= 3.32; 95%CI= 0.12 to 0.77; p<0.001), food buying habits at roadside stalls (OR= 8.64; 95%CI= 0.03 to 0.50; p<0.001), and washing hands before eating (OR= 0.29; 95%CI= 1.80 to 25.50; p= 0.006) were significantly associated with toxoplasmosis among married women. Conclusion: Environmental and behavior factors are positively associate with toxoplasmosis among married women.

Background. Automated-entry consumer devices that collect and transmit patient-generated health data (PGHD) are being evaluated as potential tools to aid in the management of chronic diseases. The need exists to evaluate the evidence regarding consumer PGHD technologies, particularly for devices that have not gone through Food and Drug Administration evaluation. Purpose. To summarize the research related to automated-entry consumer health technologies that provide PGHD for the prevention or management of 11 chronic diseases. Methods. The project scope was determined through discussions with Key Informants. We searched MEDLINE and EMBASE (via EMBASE.com), In-Process MEDLINE and PubMed unique content (via PubMed.gov), and the Cochrane Database of Systematic Reviews for systematic reviews or controlled trials. We also searched ClinicalTrials.gov for ongoing studies. We assessed risk of bias and extracted data on health outcomes, surrogate outcomes, usability, sustainability, cost-effectiveness outcomes (quantifying the tradeoffs between health effects and cost), process outcomes, and other characteristics related to PGHD technologies. For isolated effects on health outcomes, we classified the results in one of four categories: (1) likely no effect, (2) unclear, (3) possible positive effect, or (4) likely positive effect. When we categorized the data as “unclear” based solely on health outcomes, we then examined and classified surrogate outcomes for that particular clinical condition. Findings. We identified 114 unique studies that met inclusion criteria. The largest number of studies addressed patients with hypertension (51 studies) and obesity (43 studies). Eighty-four trials used a single PGHD device, 23 used 2 PGHD devices, and the other 7 used 3 or more PGHD devices. Pedometers, blood pressure (BP) monitors, and scales were commonly used in the same studies. Overall, we found a “possible positive effect” of PGHD interventions on health outcomes for coronary artery disease, heart failure, and asthma. For obesity, we rated the health outcomes as unclear, and the surrogate outcomes (body mass index/weight) as likely no effect. For hypertension, we rated the health outcomes as unclear, and the surrogate outcomes (systolic BP/diastolic BP) as possible positive effect. For cardiac arrhythmias or conduction abnormalities we rated the health outcomes as unclear and the surrogate outcome (time to arrhythmia detection) as likely positive effect. The findings were “unclear” regarding PGHD interventions for diabetes prevention, sleep apnea, stroke, Parkinson’s disease, and chronic obstructive pulmonary disease. Most studies did not report harms related to PGHD interventions; the relatively few harms reported were minor and transient, with event rates usually comparable to harms in the control groups. Few studies reported cost-effectiveness analyses, and only for PGHD interventions for hypertension, coronary artery disease, and chronic obstructive pulmonary disease; the findings were variable across different chronic conditions and devices. Patient adherence to PGHD interventions was highly variable across studies, but patient acceptance/satisfaction and usability was generally fair to good. However, device engineers independently evaluated consumer wearable and handheld BP monitors and considered the user experience to be poor, while their assessment of smartphone-based electrocardiogram monitors found the user experience to be good. Student volunteers involved in device usability testing of the Weight Watchers Online app found it well-designed and relatively easy to use. Implications. Multiple randomized controlled trials (RCTs) have evaluated some PGHD technologies (e.g., pedometers, scales, BP monitors), particularly for obesity and hypertension, but health outcomes were generally underreported. We found evidence suggesting a possible positive effect of PGHD interventions on health outcomes for four chronic conditions. Lack of reporting of health outcomes and insufficient statistical power to assess these outcomes were the main reasons for “unclear” ratings. The majority of studies on PGHD technologies still focus on non-health-related outcomes. Future RCTs should focus on measurement of health outcomes. Furthermore, future RCTs should be designed to isolate the effect of the PGHD intervention from other components in a multicomponent intervention.
