title: AEROBIC TRAINING IN OBESE ADOLESCENTS: A MULTIDISCIPLINARY APPROACH

description: ABSTRACT Introduction: The prevalence of excess weight/obesity in adolescence has increased, and physical training may be effective in combating this scenario. Objective: To analyze the effect of different intensities of aerobic training on the body composition of obese adolescents undergoing multidisciplinary intervention. Methods: In this study, 107 pubertal (Tanner 3 and 4), obese (BMI=34.72±4.10 kg/m²) adolescents (14.85±1.44 years) were randomly assigned to three groups: high intensity training (HITG – ventilatory threshold I (VTI)); low intensity training (LITG – 20% below the VTI) and control group (CG), without intervention. The adolescents in the HITG and LITG underwent nutritional and psychological (1x/week) and clinical (1 x/month) follow-up and physical training (3x/week) for 12 weeks. Results: Reductions in fat mass (FM) and body fat percentage (BFP) (p&lt; 0.001) and an increase in fat-free mass (FFM) (p&lt;0.001) were observed in all groups. There was a reduction in BMI only in the experimental groups (p&lt;0.001). Conclusion: The effects of multidisciplinary treatment on the body composition of obese adolescents occur independently of the intensity of aerobic physical training. Level of Evidence I; High quality randomized clinical studies with or without statistically significant difference, but with narrow confidence intervals.

title: EFFECTS OF REPEATED SPRINT TRAINING ON ISOCAPNIC BUFFERING PHASE IN VOLLEYBALL PLAYERS

description: ABSTRACT Introduction: The region between the ventilatory threshold (VT) and respiratory compensation point (RCP) is defined as the isocapnic buffering (ICB) phase and represents a phase of compensation for exercise-induced metabolic acidosis. There is sparse literature examining the effects of physical training on ICB phase in athletes. Objectives: The purpose of this study was to examine the effects of a repeated sprint training program on the ICB phase of college volleyball players. Methods: Eighteen male volleyball players were randomly assigned to either an experimental group (n=9) or a control group (n=9) and followed a traditional volleyball training program three times per week for six weeks. The experimental group additionally performed a repeated sprint training protocol immediately before each volleyball training session. Before and after the 6-week training period, all participants performed an incremental treadmill test to determine VT, RCP, and maximal oxygen uptake (VO2max). The ICB phases were calculated as VO2 (ml/kg/min) and sprint speed (km/h). Results: The experimental group showed significant improvements in ICB phase, RCP, VO2max and maximal sprint speed after training (p&lt;0.01). There were no significant changes in VT after training in the experimental group (p&gt;0.05). None of these variables changed significantly in the control group (p&gt;0.05). Conclusions: These findings indicate that repeated sprint training can enhance the ICB phase of volleyball players, which may be attributable to an improvement in buffering capacity leading to a shift in RCP towards higher intensities without any change in VT. The increase in the ICB phase may an important factor in terms of improvement in the high-intensity exercise tolerance of athletes. Level of Evidence II; Therapeutic studies - Investigating the results of treatment.

title: Herpes zoster ophthalmicus and varicella zoster virus vasculopathy

description: ABSTRACT Herpes zoster (HZ) corresponds to the reactivation of varicella zoster virus (VZV). Among adults, the ophthalmic division of the trigeminal nerve is one of the most common sites of involvement. Vasculopathy caused by HZ is associated with significant morbidity and mortality, affecting structures such as the brain, which can lead to stroke. In this review, we analyzed the epidemiological and clinical aspects of the vascular involvement of VZV, focusing on the peculiarities of its association with ocular HZ. A review of the available literature indicated that ocular involvement of HZ was a risk factor for vasculopathy after adjusting for age, sex, body mass index, smoking, indicators of metabolic syndrome, and vascular and heart diseases. Considering the severity of this complication, vascular disease mediated by VZV requires early diagnosis and aggressive treatment. Finally, the anti-HZ vaccine has been recommended as a prophylactic measure in the elderly, but it should be used with caution in immunocompromised individuals.

title: Mental Health of First-Year Academics in the Medical School: a Gender Approach

description: ABSTRACT The medical school has a high academic load and usually demands a great student involvement. As a result, medical students may experience high prevalence of stress, Burnout syndrome and even depressive symptoms. Such factors can compromise the students’ quality of life. All of these aspects emphasize the need of deeper studies of this population group, especially in a new context of access to higher education. The objective of this study was to evaluate the overall medical students’ mental health entering the medical school, with emphasis on quality of life, Common Mental Disorders, depressive symptoms, daytime sleepiness level and Burnout, according to the gender. This is a cross-sectional study, performed with first-year undergraduate medical students from three institutions from the north of Minas Gerais. Questionnaires were applied to evaluate daytime sleepiness, depressive symptoms, Common Mental Disorders, Burnout and quality of life, as well as a questionnaire with sociodemographic information. Academics were approached at the college where they study, at the beginning or at the end of the class. Data were analyzed using the chi-square test, and Student’s t-test for independent samples, in the comparison between genders. Data from 101 incoming students were evaluated. Stress was present in 45.5% of the students. The prevalence of depressive symptoms of varying degrees was also significant, affecting 43.6% of the students. There was a statistically significant difference in the mental component of quality of life and in the presence of Common Mental Disorders between men and women. It was possible to observe that a significant portion had pathological levels of daytime sleepiness, symptoms of Common Mental Disorders, depressive symptoms of varying degrees, emotional exhaustion and depersonalization. More than a third of the academics consider their quality of life bad when it comes to the physical and mental domain. The quality of the course and health care requires a humanized professional who seek good health, that’s why it is essential that universities discuss strategies that promote health and the prevention of symptoms that compromise the mental health of academics.

title: Plant architecture influences gall abundance in a tropical montane plant species

description: ABSTRACT Sessile and host-specific herbivores, such as gall-inducing insects, are usually patchily distributed within the populations of their host plants, and it has been suggested that both inter- and intra-plant variation affect gall abundance, distribution and survivorship. Variation in plant traits, such as size and architecture, has been previously demonstrated as a determinant of gall distribution. We examined the influence of architectural complexity of the tropical plant Galianthe brasiliensis (Rubiaceae) on the abundance of the stem-galler Lopesia sp. (Diptera, Cecidomyiidae) along an elevation gradient where both insect and plant were distributed. A total of 120 plants were sampled along the gradient and more than 580 galls were counted, while plant architectural complexity was determined by a combination of height and branch ramification. Increased elevation did not influence plant complexity nor gall abundance (both P&gt;0.05), but plant architectural complexity explained more than 60% of the variation in gall abundance along the gradient (R2=0.62, P&lt;0.001). We suggest that the greater availability of meristematic tissues in more architecturally complex plants explains the results found, as this is a key resource for gall occurrence and establishment.

title: Amblyopia: neural basis and therapeutic approaches

description: ABSTRACT Abnormalities in visual processing caused by visual deprivation or abnormal binocular interaction may induce amblyopia, which is characterized by reduced visual acuity. Occlusion therapy, the conventional treatment, requires special attention as occlusion of the fellow normal eye may reduce its visual acuity and impair binocular vision. Besides recovering visual acuity, some researchers have recommended restoration of stereoacuity and motor fusion and reverse suppression in order to prevent diplopia. Recent studies have documented that the amblyopic visual cortex has a normal complement of cells but reduced spatial resolution and a disordered topographical map. Changes occurring in the late sensitive period selectively impact the parvocellular pathway. Distinct morphophysiologic and psychophysical deficits may demand individualization of therapy, which might provide greater and longer-lasting residual plasticity in some children.

title: TRANSFER IN ORAL EXERCISES FROM THIRD SEMESTER STUDENT-TEACHERS OF ENGLISH AS A FOREIGN LANGUAGE (EFL)

description: ABSTRACT This descriptive-exploratory study was carried out within three groups of undergraduate students who were undertaking their third semester in a Colombian foreign languages teaching program over a six-month period. During this time, relevant information was collected from a recording sample in English as a foreign language and from two surveys, after a metalinguistic theoretical and practical work led by a teacher of a phonetics and phonology course. The aim in using the first instrument was to identify the transfer cases from mother tongue in the oral production of the foreign language students. The second instrument was intended to explore the perceptions that learners had on the theoretical and contrastive exercise and on their oral productions self-assessment. Results revealed that students perceived L2 phonological system as being far too different from that of their mother tongue; they also unveiled that this fact exerts interference over their oral production originating errors and that beyond the linguistic domain, there are mistakes in learners' self-regulation process.

title: Short implants versus longer implants with maxillary sinus lift. A systematic review and meta-analysis

description: Abstract This study compared the survival rate of dental implants, amount of marginal bone loss, and rates of complications (biological and prosthetic) between short implants and long implants placed after maxillary sinus augmentation. This systematic review has been registered at PROSPERO under the number (CRD42017073929). Two reviewers searched the PubMed/MEDLINE, Embase, LILACS, and Cochrane Library databases. Eligibility criteria included randomized controlled trials, comparisons between short implants and long implants placed after maxillary sinus augmentation in the same study, and follow-up for &gt;6 months. The Cochrane Collaboration’s tool for assessing the risk of bias in randomized trials was used to assess the quality and risk of bias of the included studies. The search identified 1366 references. After applying the inclusion criteria, 11 trials including 420 patients who received 911 dental implants were considered eligible. No significant difference was observed in the survival rate [p = 0.86; risk ratio (RR): 1.08; 95% confidence interval (CI): 0.46–2.52] or in the amount of marginal bone loss (p = 0.08; RR: −0.05; 95%CI: −0.10 to 0.01). However, higher rates of biological complications for long implants associated with maxillary sinus augmentation were observed (p &lt; 0.00001; RR: 0.21; 95%CI: 0.10–0.41), whereas a higher prosthetic complication rate for short implants was noted (p = 0.010; RR: 3.15; 95%CI: 1.32–7.51). Short implant placement is an effective alternative because of fewer biological complications and similar survival and marginal bone loss than long implant placement with maxillary sinus augmentation. However, the risk of mechanical complications associated with the prostheses fitted on short implants should be considered.
