The use of a biopsychosocial model in the treatment of patients with chronic.

OBJECTIVE: To explore the available knowledge on the application of biopsychosocial model (BPS) in patients with chronic low back pain (CLBP). METHODS: A scoping review, including 32 papers that used a BPS to manage adult patients with CLBP, published in any language. Six different databases were searched. RESULTS: According to the description of the protocols, most of them use BPS for assessment of the patients. In this first stage the most often evaluated were pain and disability, kinesiophobia and quality of life, and work-related factors. The intervention most used associate psychological and physical domains using pain education or cognitive functional therapy and active exercise. Even though was not the most common, in the social domain occupational, behavioral and family interventions were observed. CONCLUSION: BPS is more often used as combination of physical and psychological aspects, being the social domain restricted to work-related factors. Patien'ts perception of their health status is little explored, and it is suggested that the International Classification of Functioning, Disability and Health be used. PRACTICE IMPLICATION: Patient perception as well as social factors in addition to occupational ones should be included in the clinical approach of the patient with CLBP and should be further explored in research.

Comparison between exercise therapy and non-hydrolyzed collagen (UC-II) in functionality and quality of life in women with knee osteoarthritis : A randomized controlled clinical trial.

BACKGROUND: Knee osteoarthritis (OA) is characterized by a progressive degeneration of cartilage and menisci, leading to pain and locomotor disability. Here, we aimed to assess the effect of an exercise protocol and the oral use of non-hydrolyzed collagen (UC-II) on the functionality and quality of life of women with knee OA. MATERIAL AND METHODS: Individuals were divided into three groups (CG [control group]; MG [medication group]; EG [exercise group]). In the CG there was no intervention, while MG received an oral dose (1 capsule/day) of UC-II and the EG held 12 sessions of an exercise protocol. RESULTS: In the functionality tests (6-min walk test, 6MWT and timed up and go test [TUG]) the EG (p < 0.001/p = 0.020) and MG (p = 0.010/p = 0.010) revealed a significant improvement when compared to the CG. In the analysis of quality of life by WOMAC, a significant improvement was found only in the EG (p = 0.030) when compared to the CG; the same happened in the stiffness domain (EG, p = 0.010), despite in the pain domain, both the EG (p < 0.001) and the MG (p = 0.060) were better than the CG. CONCLUSION: Data obtained here reveal that an exercise protocol and UC-II have similar effects for functionality, despite exercise being superior in promoting the quality of life score.

Knee Osteoarthritis: Kinesiophobia and Isometric Strength of Quadriceps in Women.

Introduction: Osteoarthritis is a disease characterized by progressive wear and tear of the joint, with the knee being the most affected region. These patients have reduced mobility and mobility, among other symptoms. Thus, it is necessary to know the variables that influence the ability to walk. Objective: To analyze how much the gait capacity, in the performance of the six-minute walk test, can be influenced by the maximum isometric strength of the quadriceps or by kinesiophobia in women with knee osteoarthritis. Materials and Methods: This is a cross-sectional study with a sample of 49 women diagnosed with osteoarthritis. The evaluation was carried out in a single moment. Variables studied isometric quadriceps strength, level of fear of movement (kinesiophobia), and ability to walk. Simple linear regression analyzes were performed, with gait ability as the dependent variable and maximum isometric strength and kinesiophobia as independent. Data were presented with mean and standard deviation and were analyzed by the SPSS Statistic 22.0 software, considering p < 0.05 as significant. Results: The maximum isometric strength presents a significant difference, directly interfering with the gait ability; as kinesiophobia does not show a statistically significant difference, it does not directly interfere with the ability to walk. Conclusion: Maximal quadriceps isometric strength directly interferes with gait ability in women with knee osteoarthritis, thus suggesting the inclusion of this strategy in treatment programs for this population.

Physiological and Biochemical Evaluation of Different Types of Recovery in National Level Paralympic Powerlifting.

BACKGROUND: Recovery from training is vital as it ensures training and performance to continue at high intensities and longer durations to stimulate the body and cause further adaptations. OBJECTIVE: To evaluate different methods of post-workout recovery in Paralympic powerlifting athletes. METHODS: Twelve male athletes participated (25.4 ± 3.3 years; 70.3 ± 12.1 kg). The presence of muscle edema, pain threshold, plasma cytokines, and performance measurement were evaluated five times. The recovery methods used in this study were passive recovery (PR), dry needling (DN), and cold-water immersion (CWI). RESULTS: The data analysis showed that the maximal force decreased compared to the pretest value at 15 min and 2 h. The results also revealed that CWI and DN increased Interleukin 2 (IL-2) levels from 24 to 48 h more than that from 2 h to 24 h. After DN, muscle thickness did not increase significantly in any of the muscles, and after 2 h, muscle thickness decreased significantly again in the major pectoralis muscle. After CWI, pain pressure stabilized after 15 min and increased significantly again after 2 h for acromial pectoralis. CONCLUSION: The strength training sessions generate several changes in metabolism and different recovery methods contribute differently to maintain homeostasis in Paralympic powerlifting athletes.

Detection of hemoplasma and Bartonella species and co-infection with retroviruses in cats subjected to a spaying/neutering program in Jaboticabal, SP, Brazil.

Hemotrophic mycoplasmas and Bartonella species are important pathogens that circulate between cats and invertebrate hosts, occasionally causing diseases in humans. Nevertheless, there are few reports on occurrences of these agents in cats in Brazil. The present study aimed to detect the presence of hemoplasma and Bartonella DNA by means of PCR and sequencing. FIV antigens and anti-FeLV antibodies, were studied by using a commercial kit on blood and serum samples, respectively, among 46 cats that were sampled during a spaying/neutering campaign conducted in Jaboticabal, SP. Three (6.5%) cats were positive for hemoplasmas: two (4.3%) for 'Candidatus M. haemominutum' and one (2.2%) for both M. haemofelis and 'Candidatus M. turicensis'. One of the two 'Candidatus M. haemominutum'-infected cats was also positive for FeLV antigens and showed antibodies for FIV. Two cats (4.3%) were positive for B. henselae. One of them was also positive for FeLV antigens. Eight cats (17.4%) were positive for FeLV, and just one (2.2%) showed anti-FIV antibodies. Bartonella species and hemoplasmas associated with infection due to retroviruses can circulate among apparently healthy cats.

Micoplasmas hemotróficos e espécies de Bartonella são importantes patógenos que circulam entre gatos e hospedeiros invertebrados, causando ocasionalmente doenças no homem. Apesar disto, poucos são os estudos acerca da ocorrência destes agentes entre gatos no Brasil. O presente estudo objetivou detectar o DNA de hemoplasmas e Bartonella sp. pela PCR e sequenciamento. Antígeno de FIV e anticorpos anti-FeLV foram estudados utilizando um "kit" comercial, em amostras de sangue e soro, respectivamente, de 46 gatos amostrados em uma campanha de castração em Jaboticabal, SP. Três gatos (6,5%) foram positivos para hemoplasmas: dois (4,3%) para 'Candidatus M. haemominutum' e um (2,2%) para M. haemofelis and 'Candidatus M. turicensis'. Um dos gatos positivos para 'Candidatus M. haemominutum' mostrou-se também positivo na detecção de antígeno de FeLV e de anticorpos para FIV. Dois (4,3%) gatos mostraram-se positivos para B. henselae, sendo que um deles também se mostrou positivo para antígeno de FeLV. Oito gatos (17,4%) foram positivos para FeLV, e apenas um gato mostrou anticorpos anti-FIV. Bartonella sp. e hemoplasmas associados à infecção por retrovírus podem circular entre gatos aparentemente saudáveis.

Estimation of the diagnostic accuracy of the glyco-C and US9 gene-based polymerase chain reaction technique for the detection of bovine Herpesvirus type 5 DNA in decomposed brain suspension from a slaughter house using Bayesian analysis, Brazil.

Brazil represents the greatest beef producer among tropical countries, and the major obstacle for meat international trade is sanitary problems especially closely related to viral encephalitis. The goal of this study was to estimate the accuracy of the glycol and US9 gene-based polymerase chain reactions (PCRs) for the detection of bovine Herpesvirus type 5 (BoHV-5) from decomposed brain samples (n = 95). For this purpose, a latent-class (bayesian) approach was used. Sensitivity (Se) was estimated to be 70% (95% probability interval, 40-80) and specificity (Sp) 100% in the statistical analysis for both PCRs used. Accordingly, a minimum of ≥40% of the calves was estimated to harbor BoHV-5 DNA even after 72 h of decomposition at room temperature. It was concluded that US9 gene-based PCR could also be considered a cost-effective alternative in sanitary programmers. However, given the importance of veterinary diagnoses, PCR-positive samples should be further confirmed through in vitro isolation and/or sequencing.

A new algorithm for segmenting and counting Aedes aegypti eggs in ovitraps.

Dengue fever has become a major international public health concern in recent decades. As dengue fever not have available vaccine or specific treatment, the only known form to prevent the illness is by applying strategies to control its vector, the Aedes aegypti mosquito. Ovitraps, special traps to collect mosquito eggs, are used to detect Aedes aegypti presence and to approximate the gauge of the adult mosquitoes population in the environment by counting the number of eggs laid in an trap. This counting is usually performed in a manual, visual and non-automatic form. This work proposes a new automatic method to automatically count the number of eggs in digital images of ovitraps based on image processing techniques (color systems exploration) and k-Means clustering algorithm. The proposed method performs an improvement on the results when compared with previous studies.
