Effect of 4 weeks of plyometric training in the pre-competitive period on volleyball athletes' performance.

We aimed to evaluate the effect of 4 weeks of plyometric training (PT), performed in the pre-competitive period, on the vertical jump performance of professional volleyball athletes. We recruited 17 professional female volleyball players (age: 19 ± 3 years; weight: 67.2 ± 5.50 kg; height: 1.81 ± 0.22 m; body fat: 14.4 ± 2.12%; squat 1RM test: 75.5 ± 7.82 kg; training time experience: 6.2 ± 3.4 years) to participate in four weeks of training and assessments. They were divided into an experimental group (EG = 9) and a control group (CG = 8). Both groups were submitted to friendly matches, technical, tactical and resistance training (4 weeks/˜9 sessions per week), and internal load monitoring was carried out. The EG performed PT twice a week. At the beginning and end of the four weeks, jump tests were performed. The main findings are: 1) PT when incorporated into the pre-competitive period can induce greater improvements in jumping performance (EG = 28.93 ± 3.24 cm to 31.67 ± 3.39 cm; CG = 27.91 ± 4.64 cm to 28.97 ± 4.58 cm; when comparing the percentage delta, we found a difference between groups with ES of 1.04 and P = 0.02); 2) this result is observed when the training load is similar between groups and increases over the weeks, respecting the linear progression principle. Therefore, including plyometric training in the preparatory period for volleyball, with low monotony and training strain increment, is an effective strategy for further CMJ performance improvement.

Magnetic Resonance Imaging and Pelvic Fracture Urethral Injuries.

Pelvic fracture urethral injuries (PFUI) are devastating lesions that lead to fibrosis and urethral disruption, which result in recurrent strictures, urinary incontinence, fistulae, and even erectile dysfunction, representing a management problem for the urologist. Magnetic resonance imaging (MRI) may be a valuable tool in establishing or confirming the diagnosis by providing detailed anatomy and estimating disease extent. We present a comprehensive review of the current literature on the role of MRI on diagnostic evaluation and surgical management of patients with PFUI.

Análisis del entrenamiento resistido en el perfil glicémico: una revisión bibliográfica / Analysis of the resistance training in the glycemic profile: a bibliographic review

La presente revisión bibliográfica surge de la necesidad de revisar la evidencia sobre el efecto del entrena-miento resistido en el perfil glicémico. La búsqueda de información se realiza en las bases de datos Ebsco, PubMed, Google Académico y Researchgate, restringida a publicaciones de los años 2011 a 2016. Se utiliza-ron las siguientes palabras clave: Entrenamiento de Resistencia y de control de la diabetes, el Entrenamiento de Resistencia y el control de glucémico, el Entrenamiento de Resistencia y Control de la Salud. Fueron encontrados 841 artículos, a continuación, se excluyeron los artículos que no cumplían con los criterios de inclusión del estudio, de estos 75 fueron excluidos porque no manifestaran el efecto del entrenamiento de resistencia en la glucosa. Finalmente solo 6 estudios fueron seleccionados y analizados para la presente investigación. Los resultados de esta revisión muestran que los métodos de ER, se consideran importantes componentes cuando el objetivo principal es preservar el buen estado de salud, interviniendo positivamente en el perfil glucémico y minimizando los factores de riesgo inherentes a una dieta pobre y estilo de vida sedentario, demostrando que no es sólo el entrenamiento aeróbico el que puede mantener el buen estado de salud.

The present literature review arises from the need to review the evidence on the effect of resistance training on the glycemic profile. The search for information is carried out in the Ebsco, PubMed, Google Scholar and Researchgate databases, restricted to publications from the years 2011 to 2016. The following keywords were used: Resistance training and diabetes control, Resistance and glycemic control, Resistance Training and Health Control. 841 articles were found. Then, articles that did not meet the inclusion criteria of the research were excluded, and from those, 75 more were excluded because they did not manifest the effect of resistance training on glucose. Finally, only 6 research studies were selected and analyzed for this investiga-tion. The results of this review show that RT methods are considered important components when the main objective is to maintain good health by positively intervening on the glycemic profile and by minimizing risk factors inherent to a poor diet and a sedentary lifestyle, and therefore demonstrating that it is not just aerobic training that can maintain good health.

In vitro anti-Candida activity of selective serotonin reuptake inhibitors against fluconazole-resistant strains and their activity against biofilm-forming isolates.

Recent research has shown broad antifungal activity of the classic antidepressants selective serotonin reuptake inhibitors (SSRIs). This fact, combined with the increased cross-resistance frequency of the genre Candida regarding the main treatment today, fluconazole, requires the development of novel therapeutic strategies. In that context, this study aimed to assess the antifungal potential of fluoxetine, sertraline, and paroxetine against fluconazole-resistant Candida spp. planktonic cells, as well as to assess the mechanism of action and the viability of biofilms treated with fluoxetine. After 24 h, the fluconazole-resistant Candida spp. strains showed minimum inhibitory concentration (MIC) in the ranges of 20-160 µg/mL for fluoxetine, 10-20 µg/mL for sertraline, and 10-100.8 µg/mL for paroxetine by the broth microdilution method (M27-A3). According to our data by flow cytometry, each of the SSRIs cause fungal death after damaging the plasma and mitochondrial membrane, which activates apoptotic signaling pathways and leads to dose-dependant cell viability loss. Regarding biofilm-forming isolates, the fluoxetine reduce mature biofilm of all the species tested. Therefore, it is concluded that SSRIs are capable of inhibit the growth in vitro of Candida spp., both in planktonic form, as biofilm, inducing cellular death by apoptosis.

Malignant priapism: Penile metastasis originating on a primary prostate adenocarcinoma.

Malignant priapism is a definition invented in 1938 by Peacock, defined as a persistent erection, not related with sexual activity, caused by cavernous sinus and associated venous systems invasion with malignant cells. Penile secondary lesions are rare entities. Primary locations are usually the pelvic cavity organs, namely the prostate and the bladder as the most common ones. Priapism as a first manifestation of these kinds of lesions is even rarer. The aim was to present a 52-year-old patient harboring a penile metastasis that originated in the primary prostate adenocarcinoma, manifesting itself as a "common" priapism. The patient referred to the emergency room presenting with a priapism and nodules at the coronal sulcus, without previous similar episodes. His evolution until properly diagnosed was catastrophic with multiple lymph nodes, bone and organ involvement, and with his demise soon after from serious bleeding and congestive heart failure, almost 2 months after he first came to the emergency room. We review the literature concerning malignant priapism, diagnosis, and current treatment and survival perspectives.

Results of arthroscopic partial repair of large retracted rotator cuff tears.

PURPOSE: To evaluate the midterm results of partial rotator cuff repair using the Constant score and the acromiohumeral radiographic measurement. METHODS: Thirty-eight patients with a mean age of 65 years and a large retracted rotator cuff tear (at least 2 tendons) were included in the study. Patients underwent clinical examination, standard radiography, and isometric strength testing at a mean follow-up of 47 months. The rotator cuff tears were classified as posterosuperior, anterosuperior, or global tears (≥3 tendons), and an arthroscopic partial repair was performed. RESULTS: The mean Constant score significantly increased from 56 points before surgery to 71 points after surgery (P = .041); the mean age- and sex-adjusted Constant score significantly improved from 63% to 90% at a mean follow-up of 47 months after arthroscopic partial rotator cuff repair (P = .003); and the subcategories pain and activity significantly improved (P = .001, P = .014, respectively). The active range of motion improved from 133° of flexion and 111° of abduction before surgery to 163° of forward flexion and 156° of abduction after surgery (P < .001). However, the active range of external rotation decreased from 44° before surgery to 36° after surgery. Further, there was a trend toward a decrease in the mean acromiohumeral distance from 7.0 mm before surgery to 5.6 mm after surgery. The abduction strength did not significantly improve after surgery (4.2 kg before surgery and 4.8 kg after surgery; P = .116). CONCLUSIONS: An arthroscopic partial repair of the rotator cuff is an effective tool to improve the Constant score by restoring active forward flexion and abduction and through pain relief. Further, we found that a pathologically decreased acromiohumeral distance cannot be reversed by a partial rotator cuff repair. LEVEL OF EVIDENCE: Level IV, therapeutic case series.
