Long-term outcome of implants exhibiting buccal soft tissue dehiscence in the esthetic zone.

OBJECTIVE: Increasing aesthetic demands require that the color and contour of the peri-implant soft tissues be in harmony with the neighboring teeth. Recession, migration toward the apical, is a frequent clinical finding. Its presence can lead to inflammation and increased marginal bone loss. These complications, in addition to affecting the aesthetic results of our treatment, are difficult to treat and can threaten the survival of the implant. There are fewer studies showing the outcome of treatment of soft-tissue defects around implants. The aim of this article is to describe the treatment of a soft-tissue defect around an implant-supported prosthesis treatment, performed on two neighboring implants, in the esthetic zone in a patient with a high smile and to evaluate both the coverage achieved and the patient's esthetic satisfaction. CLINICAL CONSIDERATIONS: This study showed that a mucogingival approach, using a surgical technique designed for the treatment of alveolar ridge defects, together with tissue management with temporaries and a new restoration, achieved an optimal result. CONCLUSIONS: The case has been closely followed up, for 10 years, and the authors have been able to confirm the long-term stability of the result. CLINICAL SIGNIFICANCE: The following paper shows the result of an innovative approach. Connective tissue platform technique, usually performed for soft-tissue augmentation, was used for a defect in soft-tissue dehiscence. The authors followed the results for 10 years, and the results achieved were satisfactory in terms of esthetic.

Low-Cost Algorithms for Metabolic Pathway Pairwise Comparison.

Metabolic pathways provide key information for achieving a better understanding of life and all its processes; this is useful information for the improvement of medicine, agronomy, pharmacy, and other similar areas. The main analysis tool used to study these pathways is based on pathway comparison, using graph data structures. Metabolic pathway comparison has been defined as a computationally complex task. In a previous work, two new algorithms were introduced to treat the problem of metabolic pathway pairwise comparison. Here we provide an extended analysis with more data and a deeper analysis of metabolic pathway comparison as listed in the discussion and results section.

Comparison of Mechanical Outputs Between the Traditional and Ballistic Bench Press: Role of the Type of Variable.

Pestaña-Melero, FL, Jaric, S, Pérez-Castilla, A, Rojas, FJ, and García-Ramos A. Comparison of mechanical outputs between the traditional and ballistic bench press: role of the type of variable. J Strength Cond Res 34(8): 2227-2234, 2020-This study aimed to comprehensively explore the differences in mechanical outputs between the bench press (BP) and the bench press throw (BPT) exercises performed by 21 men (age: 22.0 ± 4.2 years, body mass: 73.4 ± 7.7 kg, height: 177.2 ± 8.0 cm, and concentric-only [C-O] BP 1 repetition maximum: 81.3 ± 6.8 kg) against a fixed external load of 27 kg using both the (C-O) and eccentric-concentric (E-C) execution techniques. The types of variables collected by means of a linear velocity transducer were the traditional mean values (i.e., from the first positive velocity until the barbell reaches maximum height), mean propulsive values (i.e., from the first positive velocity until the barbell acceleration become lower than gravity), mean values of the acceleration phase (i.e., from the first positive velocity until the barbell acceleration become negative), and maximum values (i.e., the highest instantaneous value of the concentric phase) of force, velocity, and power. The magnitude of the effect sizes (the negative sign indicates a higher value for the BP as compared to the BPT) ranged from -0.10 to -2.19 for force, 0.28 to 1.30 for velocity, and -0.73 to 0.67 for power variables, remaining mainly similar for the (C-O) and (E-C) execution techniques. These results highlight that the comparison of force, velocity, and power outputs between the BP and BPT exercises is largely affected by the type of variable considered. The shortcomings of linear position transducers in accurately determining the end point of the concentric phase suggest that the maximum values, particularly the maximum velocity, should be reported to assess ballistic performance.

Mean Velocity vs. Mean Propulsive Velocity vs. Peak Velocity: Which Variable Determines Bench Press Relative Load With Higher Reliability?

García-Ramos, A, Pestaña-Melero, FL, Pérez-Castilla, A, Rojas, FJ, and Haff, GG. Mean velocity vs. mean propulsive velocity vs. peak velocity: which variable determines bench press relative load with higher reliability? J Strength Cond Res 32(5): 1273-1279, 2018-This study aimed to compare between 3 velocity variables (mean velocity [MV], mean propulsive velocity [MPV], and peak velocity [PV]): (a) the linearity of the load-velocity relationship, (b) the accuracy of general regression equations to predict relative load (%1RM), and (c) the between-session reliability of the velocity attained at each percentage of the 1-repetition maximum (%1RM). The full load-velocity relationship of 30 men was evaluated by means of linear regression models in the concentric-only and eccentric-concentric bench press throw (BPT) variants performed with a Smith machine. The 2 sessions of each BPT variant were performed within the same week separated by 48-72 hours. The main findings were as follows: (a) the MV showed the strongest linearity of the load-velocity relationship (median r = 0.989 for concentric-only BPT and 0.993 for eccentric-concentric BPT), followed by MPV (median r = 0.983 for concentric-only BPT and 0.980 for eccentric-concentric BPT), and finally PV (median r = 0.974 for concentric-only BPT and 0.969 for eccentric-concentric BPT); (b) the accuracy of the general regression equations to predict relative load (%1RM) from movement velocity was higher for MV (SEE = 3.80-4.76%1RM) than for MPV (SEE = 4.91-5.56%1RM) and PV (SEE = 5.36-5.77%1RM); and (c) the PV showed the lowest within-subjects coefficient of variation (3.50%-3.87%), followed by MV (4.05%-4.93%), and finally MPV (5.11%-6.03%). Taken together, these results suggest that the MV could be the most appropriate variable for monitoring the relative load (%1RM) in the BPT exercise performed in a Smith machine.

Efectividad de la lacosamida en el tratamiento del dolor neuropático refractario: estudio observacional abierto / Effectiveness of lacosamide in the treatment of refractory neuropathic pain: an open observational trial

Introducción. Aunque se dispone de diferentes tratamientos para el dolor neuropático, en muchas ocasiones estos pacientes son refractarios, lo que hace necesario probar tratamientos que, por su utilidad en otras patologías, podrían ser eficaces en el dolor neuropático. Pacientes y métodos. Se recogieron las historias clínicas de pacientes que hubieran sido tratados con lacosamida para el dolor neuropático, en diferentes hospitales de la zona centro peninsular, y que cumplieran unas características similares en cuanto a refractariedad a otros tratamientos estándares, en un seguimiento de al menos seis meses, o que hubiesen tenido que suspender el tratamiento con dicho fármaco por cualquier motivo. Se obtuvo una muestra de 114 pacientes, 61 varones y 53 mujeres, con una edad media de 60,5 años. Resultados. Las causas de dolor neuropático más frecuentes fueron: polineuropatía diabética (31,6%), neuralgia postherpética (22,8%), neuralgia del trigémino (17,5%), neuralgia suboccipital y lumbociatalgia (un 12,3% en ambas). La eficacia fue buena/muy buena en la mayoría de los pacientes, con un descenso medio en la escala analógica visual tras seis meses de 7,7 a 4,8. No se registraron efectos secundarios graves en ningún paciente, pero en 12 y 10 pacientes no hubo registro más allá de seis meses, por ineficacia e intolerancia al tratamiento, respectivamente. Conclusiones. El tratamiento con lacosamida en el dolor neuropático de diferentes causas podría considerarse como una alternativa efectiva y bien tolerada para aquellos pacientes que no respondan a los tratamientos estándares (AU)

Introduction. Although different treatments are available for neuropathic pain, these patients are often refractory, which makes it necessary to test treatments that, as they have proven useful in other pathologies, could be effective in neuropathic pain. Patients and methods. The study made use of the medical records of patients who had been treated with lacosamide for neuropathic pain in different hospitals in the central area of the peninsula and who fulfilled similar characteristics in terms of refractoriness to other standard treatments, in a follow-up that lasted at least six months, or who had had to stop treatment with that drug for some reason or another. A sample of 114 patients (61 males and 53 females) with a mean age of 60.5 years was obtained from the data. Results. The most common causes of neuropathic pain were: diabetic polyneuropathy (31.6%), post-herpes neuralgia (22.8%), trigeminal neuralgia (17.5%), suboccipital and lumbar-radicular neuralgia (both 12.3%). Effectiveness was good/ very good in most patients, with the mean score on the visual analogue scale after six months dropping from 7.7 to 4.8. No serious side effects were reported in any of the patients, but in 12 and 10 patients no recordings were made beyond six months, due to ineffectiveness and intolerance to the treatment, respectively. Conclusions. Treatment with lacosamide in neuropathic pain due to different causes could be considered an effective and well-tolerated alternative for patients who fail to respond to standard treatments (AU)

Response timing in the lunge and target change in elite versus medium-level fencers.

The aim of the present work is to examine the differences between two groups of fencers with different levels of competition, elite and medium level. The timing parameters of the response reaction have been compared together with the kinetic variables which determine the sequence of segmented participation used during the lunge with a change in target during movement. A total of 30 male sword fencers participated, 13 elite and 17 medium level. Two force platforms recorded the horizontal component of the force and the start of the movement. One system filmed the movement in 3D, recording the spatial positions of 11 markers, while another system projected a mobile target over a screen. For synchronisation, an electronic signal enabled all the systems to be started simultaneously. Among the timing parameters of the reaction response, the choice reaction time (CRT) to the target change during the lunge was measured. The results revealed differences between the groups regarding the flight time, horizontal velocity at the end of the acceleration phase, and the length of the lunge, these being higher for the elite group, as well as other variables related to the temporal sequence of movement. No significant differences have been found in the simple reaction time or in CRT. According to the literature, the CRT appears to improve with sports practice, although this factor did not differentiate the elite from medium-level fencers. The coordination of fencing movements, that is, the right technique, constitutes a factor that differentiates elite fencers from medium-level ones.

Regeneración periodontal en defectos intraóseos de 2-3 paredes con tres membranas diferentes: Un ensayo clínico randomizado / Periodontal regeneration in two and three-wall intrabony defects by the use of three different barrier membranes. A randomized clinical study

Fundamento: El objetivo del presente artículo es valorar la eficacia clínica, medida en términos de ganancia de inserción clínica, de dos membranas reabsorbibles, frente a un control positivo, membrana no reabsorbible, en el tratamiento de defectos intraóseos de 2-3 paredes. Pacientes y método: Seleccionamos 36 pacientes en los que detectamos 43 lesiones intraóseas de 2-3 paredes. Previamente a la cirugía se registró la profundidad de sondaje y la recesión gingival (nivel de inserción clínica). Tras el abordaje con un colgajo de espesor total, el desbridamiento y medición de los defectos y la instrumentación de la pared radicular, se colocó la membrana. Se realizó un seguimiento clínico a las 1, 2, 4, 6, 8 semanas, 3, 6 y 12 meses, y radiográfico a los 6 y 12 meses. Resultados: Finalizaron el estudio 36 defectos, correspondientes a 30 pacientes. Al año hubo una reducción en la media de la profundidad de sondaje de 3,98 mm, un incremento de la recesión de 0,17 mm y la ganancia clínica de inserción (NCI) fue de 3,97 mm. No encontramos diferencias significativas entre las diferentes membranas utilizadas (AU)

Background: A study is made to evaluate the clinical efficacy, in terms of clinical attachment gained, of two resorbable membranes versus a positive control (non-resorbable membrane), in the treatment of two-three wall intrabony defects. Patients and method: We selected 36 patients in whom 43 two-three wall intrabony lesions were detected. Prior to surgery we recorded pocket depth and gingival recession (clinical attachment level). After a full thickness flap approach, debridement and measurement of the defects, and instrumentation of the root wall, the membrane was placed. Clinical follow-up was carried out after 1, 2, 4, 6 and 8 weeks, and 3, 6 and 12 months, with radiological controls after 6 and 12 months. Results: A total of 36 defects completed the study, corresponding to 30 patients. After one year a mean reduction in pocket depth of 3.98 mm was recorded, with a 0.17 mm recession increment and a clinical attachment gain (NCI) of 3.97 mm. No significant differences were observed between the different membranes used (AU)

Colutorios para el control de placa y gingivitis basados en la evidencia científica / Mouthrinses with evidence-based control of plaque and gingivitis

La alta incidencia de enfermedad periodontal entre los adultos indica que en la mayoría de casos la higiene oral diaria podría y debería ser mejorada considerablemente. Las limitaciones de las prácticas de higiene cotidianas sugieren que se necesita la aplicación de otras estrategias. Los colutorios, en particular, la clorhexidina y los aceites esenciales disminuyen la formación de placa y la gingivitis, incluso en zonas de difícil acceso, teniendo excelentes características de seguridad y tolerabilidad. Además, de la clorhexidina y los aceites esenciales, entre los antisépticos comunes en los colutorios se incluyen, el triclosán, la hexetidina, los compuestos de amonio cuaternario, el delmopinol, la sanguinarina, y otros. Existe evidencia científica que los enjuagues con colutorios pueden desempeñar un papel clave y de un valor significativo como coadyuvantes de los métodos mecánicos para la prevención y tratamiento de las enfermedades periodontales. No obstante, en ningún caso pueden sustituir al control mecánico de la placa sino que actuarán como coadyuvante del mismo

The high incidence of periodontal disease among adults indicates that in most cases oral hygiene could and should be considerably improved. The limitations of routine hygiene practices suggest that the application of other strategies is required. Mouthrinses, particularly chlorhexidine and essential oils, reduce the formation of plaque and gingivitis, even in areas of difficult access, and are characterized by their excellent safety and tolerability. Apart from chlorhexidine and essential oils, the antiseptics commonly found in mouthrinses include among others triclosan, hexetidine, quaternary ammonium compounds, delmopinol, and sanguinarine. There is scientific evidence that indicates that mouthrinses can play a key role and have a significant value as an adjunct to mechanical methods for the prevention and treatment of periodontal diseases. However, they under any circumstance cannot be a substitute for mechanical oral-care methods

Prediction of distance in hammer throwing.

The aim of this study was to determine how much the predicted distance of a hammer throw is affected by (1) ignoring air resistance and (2) assuming that the centre of mass of the hammer coincides with the centre of the ball. Three-dimensional data from actual throws (men: 72.82 +/- 7.43 m; women: 67.78 +/- 4.02 m) were used to calculate the kinematic conditions of the hammer at release. A mathematical model of the hammer was then used to simulate the three-dimensional airborne motion of the hammer and to predict the distance of the throw. The distance predicted for vacuum conditions and using the ball centre to represent the hammer centre of mass was 4.30 +/- 2.64 m longer than the official distance of the throw for the men and 8.82 +/- 3.20 m longer for the women. Predictions using the true centre of mass of the hammer reduced the discrepancy to 2.39 +/- 2.58 m for the men and 5.28 +/- 2.88 m for the women. Predictions using air resistance and the true centre of mass of the hammer further reduced the discrepancy to -0.46 +/- 2.63 m for the men and 1.16 +/- 2.31 m for the women. Approximately half the loss of distance produced by air resistance was due to forces made on the ball and the remainder to forces made on the cable and handle. Equations were derived for calculation of the effects of air resistance and of the assumption that the centre of mass of the hammer coincides with the centre of the ball, on the distance of the throw.
