ABSTRACT
BACKGROUND: Neck pain is a prevalent global musculoskeletal issue, significantly contributing to the loss of years of healthy life due to disability. Chronic nonspecific neck pain (CNNP) involves diverse symptoms impacting mobility and quality of life. While therapeutic exercises demonstrate efficacy, the role of photobiomodulation therapy (PBMT) remains uncertain. This study aims to assess the additional effects of PBMT within a multimodal therapeutic intervention for CNNP. METHODS: A randomized, two-arm, controlled, blind clinical trial follows CONSORT and SPIRIT guidelines. Participants diagnosed with CNNP will receive a stand-alone multimodal therapeutic intervention or the same program with additional PBMT. The primary outcomes will be assessed by the functional disability identified through applying the NDI (Neck Disability Index). Secondary outcomes will be pain intensity during rest and active neck movement, catastrophizing and kinesiophobia, functionality, and disability assessed at baseline, after 8 weeks, and at a 4-week follow-up. Both groups receive pain education before personalized interventions, including resistance exercises, neuromuscular activities, mobility, and body balance. The PBMT group undergoes low-level light therapy. Intention-to-treat analysis, using linear mixed models, employs data presented as mean, standard deviation, and differences with a 95% confidence interval. Non-normally distributed variables transform. Statistical significance is set at 5%. DISCUSSION: This study addresses a critical gap in understanding the combined effects of PBMT and therapeutic exercises for CNNP. The findings aim to guide clinicians, researchers, and CNNP sufferers through rigorous methodology and diverse outcome assessments, offering valuable insights into evidence-based practices for CNNP management. Data confidentiality is maintained throughout, ensuring participant privacy during statistical analysis. TRIAL REGISTRATION: Effects of adding photobiomodulation to a specific therapeutic exercise program for the treatment of individuals with chronic nonspecific neck pain, registration number: NCT05400473, on 2022-05-27.

INTRODUCTION: This study evaluated the probability of developing malocclusions in mixed dentition. METHODS: A longitudinal study was conducted with 598 children (aged 5 years) in deciduous dentition. The children were followed for 3 years until mixed dentition (aged 8 years). Overjet, overbite, and transversal relations were evaluated. Bayesian models were used to analyze the data and estimate the parameters. RESULTS: The parameter θ was used for the distributions, indicating the probability of presenting a given condition with a credibility index (ICr) of 95%. After 3 years of follow-up, 121 children were reevaluated. The results showed that children have a high probability of malocclusion in mixed dentition. There was a higher probability of developing an increased overjet in the mixed dentition of 20.5% (ICr 95%, 13.6-28.4) to 48.3% (ICr 95%, 39.1-57.7) and a higher probability of having a normal overbite in the deciduous dentition and a lower probability in the mixed dentition (ICr 95%, 9.2-21.3). CONCLUSIONS: Considering the probabilistic model of Bayesian analysis, children with normal overjet in the deciduous dentition may show an increased overjet in the mixed dentition. Concerning overbite, children may present an anterior open bite during the transition between deciduous and mixed dentition, as well as self-correction of deep overbite in mixed dentition. Furthermore, they may present a posterior crossbite during the mixed dentition when there is a normal transverse relationship in the deciduous dentition.

BACKGROUND: Head and neck cancer encompasses neoplasms affecting the oral cavity, pharynx, larynx, and thyroid. Identifying factors that modulate the carcinogenesis process can aid in identifying subgroups at higher risk of developing the disease, enabling implementation of prevention programs. Vitamin D receptor polymorphisms can affect the carcinogenesis of various tumors by altering vitamin D metabolism and cellular response. METHODS: To elucidate the role of vitamin D receptor polymorphisms in head and neck cancer, a systematic review was performed, searching the Embase, PubMed, Scopus, and Lilacs databases. A total of 19 articles met the inclusion criteria. The frequency of vitamin D receptors polymorphism alleles (FokI, ApaI, BsmI, TaqI, Cdx2, rs2107301, rs2238135) was recorded and pooled to calculate the odds ratio in a meta-analysis using the Review Manager software. RESULTS: Subgroup analysis demonstrated significant associations in the anatomical site of cancer (oral cancer in ApaI and BsmI, and unspecified subsites of head and neck cancer in TaqI), genotyping method (FokI and BsmI), and continent of the study (ApaI, FokI, and BsmI). CONCLUSION: Our findings were heterogeneous, as with other evidence available in the literature. Therefore, more clinical studies with larger sample sizes are needed to obtain more accurate results on the relationship between vitamin D receptor polymorphism and head and neck cancer.

OBJECTIVE: To analyze the effects of using foam roller on pain intensity in individuals with chronic and acute musculoskeletal pain. METHODS: This systematic review was registered in the National Institute for Health Research's prospective online registry of systematic reviews (PROSPERO) under CRD42023456841. The databases Pubmed, Medline (via Ovid), Embase, BVS, and PEDro (Physiotherapy Evidence Database) were consulted to carry out this systematic review. Notably, the records of clinical trials characterized as eligible were manually searched. The search terms were: (foam rolling OR foam rolling vibration) AND (acute musculoskeletal pain) AND (chronic musculoskeletal pain). The search was performed until August 22, 2023. For the analysis of the methodological quality, the PEDro scale was used for each of the manuscripts included in the systematic review. Due to the heterogeneity in the studies included in this systematic review, performing a meta-analysis of the analyzed variables was impossible. RESULTS: Only six manuscripts were eligible for data analysis. The type of FR used was non-vibrational, being applied by a therapist in only one of the manuscripts. With an application time ranging from at least 45 s to 15 min, the non-vibrational FR was applied within a day up to six weeks. Using the PEDro scale, scores were assigned that varied between 4 and 8 points, with an average of 6 ± 1.29 points. Only two randomized clinical trials found a significant benefit in pain intensity of adding FR associated with a therapeutic exercise protocol in individuals with patellofemoral pain syndrome and chronic neck pain. CONCLUSION: The results of this systematic review do not elucidate or reinforce the clinical use of FR in pain intensity in individuals with chronic and acute musculoskeletal pain.

Sulfamethazine (SMZ), trimethoprim (TMP) and doxycycline (DOXY) are drugs of choice used in the treatment of intestinal and respiratory infections that affect poultry and swine. The aim of this study was develop and validate a simple, sensitive and fast method for the simultaneous determination of SMZ, TMP and DOXY in veterinary formulations by high-performance liquid chromatography. The separation was performed on a Macherey-Nagel C8 analytical column (4 × 125 mm, 5 µm), with a flow rate of 0.5 ml min-1 and detection at 268, 270 and 350 nm, for SMZ, TMP and DOXY, respectively. All measurements were performed in acetonitrile-water (45:55 v/v; pH 3.0). The analytical curves were linear (r > 0.9997) in the concentration range of 5.0-35.0 µg ml-1 for SMZ, 1.0-7.0 µg ml-1 for TMP and 7.0-13.0 µg ml-1 for DOXY. The method proved to be precise, robust, accurate and selective. In accelerated stability, the sample was analyzed for 6 months, with no major variations observed in organoleptic analysis and pH. Therefore, the developed method was proved to be suitable for routine quality control analyses for the simultaneous determination of SMZ, TMP and DOXY in pharmaceutical formulations.

The effect of the use of Nilo tilapia filleting residues in the production of pâtés with the addition of oregano essential oil stored for 90 days at 4 °C was evaluated. For that, 5 treatments were performed as follows: TSA-control treatment; TES with the addition of sodium erythorbate; and formulation TOE1 with 600 ppm oregano essential oil; TOE2 with 1000 ppm essential oil; and TOE3 with 1400 ppm essential oil. The pâtés showed adequate technological and physicochemical characteristics and microbiological counts within the legislation standards. No significant differences were observed in the luminosity of the pâté formulations during storage, and the addition of oil contributed to the increase in a* values and stability of b* values. Regarding the lipid and protein oxidation, TOE3 showed lower values at the end of the shelf-life. The addition of essential oil did not affect the hardness and cohesiveness of the products. The fatty acids in greater amounts in the samples were linoleic, oleic, palmitic, and stearic acids. The analysis of biogenic amines indicated that only the treatments with the highest amounts of sodium erythorbate (TES and TOE1) showed losses of spermidine. It was observed that decreasing the inclusion of sodium erythorbate and increasing the inclusion of oregano essential oil resulted in a drop in cadaverine values. A total of 46 volatile compounds were detected in the samples with the highest amount of free fatty acids and all the formulations were well accepted sensorially.

BACKGROUND: Assessment instruments play an essential role in the management of knee osteoarthritis. This study aimed to verify the clinimetric properties and validate the short version of WOMAC's (SV-WOMAC) knee with two domains, pain (four items) and physical function (eight items) in individuals with knee osteoarthritis (KO). METHODS: Reliability and internal consistency Construct, criterion validity, Ceiling, and floor effects analyses were performed. In addition to the SV-WOMAC, the following instruments were used: the numerical rating scale (NRPS), International Knee Documentation Committee (IKDC), the Short Form Health Survey (SF-36), and WOMAC's original version. Spearman's correlation coefficient (rho) was used to determine the magnitude of the correlation between the AFAQ and the other instruments. Moreover, the test-retest reliability and internal consistency were assessed using the intraclass correlation coefficient (ICC) and Cronbach's alpha, respectively. In addition, standard error of measurement (SEM) and minimum detectable change (MDC) were calculated. RESULTS: One hundred and thirteen subjects with KO were included for validity analysis, and a subsample of 53 subjects was used for test-retest reliability. Adequate reliability and internal consistency were observed with ICC ≥ 0.76, SEM ≤ 1.85, MDC ≥ 5.1, and Cronbach's alpha ≥ 0.84. Regarding construct validity, correlations greater than 0.50 were observed with the IKDC, NRPS, and functional domains of the SF-36. The SV-WOMAC showed a correlation > 0.70 with the original version and did not show ceiling and floor effects. CONCLUSION: The SV-WOMAC knee has adequate measurement properties to analyze pain and physical function in Brazilian individuals with KO.

Global growth impacts on the increased use and demand for natural resources, requiring solutions for the high volume of industrial waste and by-products generated from the most diverse commercial areas, mainly the food sector. Among the main residues with a large volume generated, those from fruit processing, grain cleaning in processing units, vegetables, and discards from the animal production industry stood out. Approximately 1.3 billion all food produced worldwide is lost or wasted per year being fruits, vegetables, roots, and tubers responsible for about half of the total amount. Many of these by-products have interesting nutrients in their composition such as fibers, proteins, and bioactive compounds. An interesting example is the sugarcane bagasse. Fibrous residue, derived from sugarcane extraction, the bagasse represents about 30-34 % of the total sugarcane mass. This is one of the most abundant cellulosic residues and contains approximately 39 % of cellulose, 28 % of hemicellulose, and 18 % of lignin. Therefore, as well as the bagasse, several residues from agroindustrial can be considered promising alternative substrates, being valuable sources for the development of high-value-added products, such as biopolymers, bioenergy, and chemical products. In addition, the reuse of agroindustrial wastes may be considered an attractive option for reducing the environmental impact caused by their generation. In the case of biopolymers, the energy savings of bio-based polymers is around 20-50 GJ/t of polymer. In this review, we have selected two commercially promising approaches to the application and use of agroindustrial residues, aiming their use for biodegradable packaging and microbial polysaccharides bio-production, improving overall sustainability and economic aspects of the scientific research, technology and modern industry.

BACKGROUND: The COVID-19 pandemic primarily impacted long-term care facilities by restricting visiting and circulation of visitors, affecting the quality of life (QoL) of older adults living in these institutions. Volunteer activities, essential for older adults' daily life, were also interrupted and potentially negatively impacted the QoL of older adults, volunteers themselves, and also employees in these institutions. In this context, this study aims to evaluate the impact of the return of volunteer-led activities in a long-term care institution on the QoL of older adult residents, employees, and volunteers. METHODS: This study used a pre-test and post-test design within the same group. The first round of data collection was conducted before volunteer-led activities returned and the second round after 1 month of return. The instrument used to assess QoL was the EUROHIS-QoL-8 scale. This study was conducted within a nursing home in São Paulo, Brazil, created in 1937 by members of the Israeli community living in Brazil. Volunteer-led activities were part of residents' daily life before the COVID-19 pandemic, when these activities were interrupted for about 20 months. A total of 79 individuals participated in both rounds (pre and post), of which: 29 residents, 27 volunteers, and 23 employees of the long-term care institution. RESULTS: Using a Wilcoxon signed-rank test, the analyses indicated improvements after the 1 month return in different QoL aspects for the three groups. Volunteers improved their personal relationships (Z - 2.332, p < .05), residents their overall health (Z - 2.409, p < .05) and employees in their overall QoL perception (Z - 2.714, p < .05). Influencing factors for residents were the number of activities (3 or more), gender (male), and education (undergraduate/graduate). For employees, those who assumed additional activities due to the volunteer-led activities interruption had a significant impact on their overall QoL. CONCLUSIONS: Evidence from this study suggests that volunteers' return positively impacted different QoL aspects for volunteers, residents, and employees.

In this work, a hydrothermal method was proposed to fabricate a nanomaterial composed of titanium dioxide and graphene oxide (10 wt%) (TiO2-GO). The GO was synthesized according to the modified Hummers and Offeman method, followed by exfoliation. Several characterization analyses were performed in order to investigate the structure, functional groups, and elemental composition of the nanomaterial. XRD analysis showed that the presence of GO does not change the crystalline structure of TiO2. FTIR evidenced the characteristic peaks present in both precursor materials (TiO2 and GO) and EDX confirmed the presence of GO on the TiO2-GO material. The nanomaterial was used as a photocatalyst in the TWW treatment, where the color and COD removal and the decrease of the characteristic peaks presented in the UV-Vis spectrum were investigated. The dosages of TiO2-GO and pH were studied to find the optimum operating condition. The results revealed that 0.5 g of photocatalyst with an initial pH of 3 achieve the best results under UV-A radiation. The kinetic test shows a COD removal of 87% after 90 min. The reuse test shows a decrease in COD removal after four cycles attributed to the deposition of some oxidized compounds on the catalyst surface. Finally, the efficiency of the photocatalyst was evaluated under solar radiation and it was shown that despite the good results, the performance of the TiO2-GO was better under UV-A radiation.

OBJECTIVE: To analyze the association between adherence to a home exercise program and central sensitization, pain intensity, and functionality in individuals with knee osteoarthritis (KOA). METHODS: A cross-sectional study was conducted involving 57 individuals with KOA. Evaluations were performed using the Exercise Adherence Rating Scale (EARS), the numerical rating scale (NRPS), the International Knee Documentation Committee (IKDC), The Central Sensitization Inventory (CSI), and the 30 sec sit and stand test (30SSST). Histograms were created to determine the normality of the data. The Kolmogorov-Smirnov test was used to determine the normality of the data. Thus, Pearson's (r) and determination (R2) correlation coefficients were calculated to determine the strength of associations between variables. RESULTS: No significant association was found between adherence behavior or reasons for adherence and central sensitization symptoms, the intensity of pain on rest and movement, knee disability symptoms, and functionality. CONCLUSION: No significant association was identified between adherence to a home exercise program and central sensitization, pain intensity, and functionality in individuals with KOA.

OBJECTIVE: To verify the effects of replacing exercises targeted on core/hip muscles by exercises targeted on leg/foot muscles in a rehabilitation program for patellofemoral pain (PFP). DESIGN: Randomized Controlled Trial. PARTICIPANTS: Fifty women with PFP. METHODS: PFP participants were randomized into the standard rehabilitation group (SRG, n = 25) or distal exercise group (DEG, n = 25). Knee pain, patient-reported function, dynamic knee valgus and muscle strength were measured at baseline and after six and twelve weeks of the program start. RESULTS: SRG and DEG presented similar responses to rehabilitation (except for muscle strengthening). Knee pain reduced after 6 weeks (SRG: -37.7%, ES = 1.23; DEG: -30%, ES = 0.93) and 12 weeks (SRG: -47.4%, ES = 1.53; DEG: -43.3%, ES = 1.46). Patient-reported function improved after 6 weeks (SRG: +7.3%, ES = 0.45; DEG: +3.8%, ES = 0.22) and 12 weeks (SRG: +14.1%, ES = 0.80; DEG: +8.8%, ES = 0.50). Dynamic knee valgus reduced after 12 weeks (SRG: -29.7%, ES = 0.38; DEG: -34.5%, ES = 0.32). Both groups experienced increases in knee extension strength (SRG: +9%, ES = 0.28; DEG: +6%, ES = -0.29), but only SRG had strength gains for hip abduction (+10%, ES = 0.36) and extension (+11%, ES = 0.44). CONCLUSION: Exercises targeted on core/hip muscles can be replaced by exercises targeted on leg/foot muscles in a lower limb exercise-based rehabilitation program for women with PFP.

ABSTRACT
Mechanical forces acting within the plant body that can mold flower shape throughout development received little attention. The palette of action of these forces ranges from mechanical pressures on organ primordia at the microscopic level up to the twisting of a peduncle that promotes resupination of a flower at the macroscopic level. Here, we argue that without these forces acting during the ontogenetic process, the actual flower phenotype would not be achieved as it is. In this review, we concentrate on mechanical forces that occur at the microscopic level and determine the fate of the flower shape by the physical constraints on meristems at an early stage of development. We thus highlight the generative role of mechanical forces over the floral phenotype and underline our general view of flower development as the sum of interactions of known physiological and genetic processes, together with physical aspects and mechanical events that are entangled towards the shaping of the mature flower.
ABSTRACT
The direct methylation method developed in this work for coffee samples allowed the determination of fatty acids using smaller sample amounts (100 mg), lower solvent volumes (5 mL) and shorter experimental run time (~12 min). Hence, the experiments are more economical and collaborate with green chemistry, besides favoring the health of the analyst who handles a smaller amount of solvents in a short period. Design Expert software was employed to determine the optimal concentration of the acid and base (0.7 e 1.75 molL-1) and evaluate the sonication time (5 min for both procedures). The experiments were carried out on different coffee samples in which the fat content ranging from 10.18% to 14.86%. The relative standard deviation values for intraday and interday were 2.78% and 7.8%, respectively, confirming the good precision of the proposed method for fatty acid derivatization.

Resumo Introdução e objetivo: a análise do sorriso diante de um tratamento odontológico é imprescindível e deve sempre levar em consideração fatores como: idade do paciente, anomalias de tamanho e forma dos dentes, formato do rosto, lábios, cor, presença de diastemas, desvios de linha média dentária, entre outros. Investigar a possível influência do desvio da linha média superior na atratividade do sorriso em adolescentes. Métodos: foram utilizadas seis fotografias frontais de sorrisos posados de voluntários adolescentes tratados ortodonticamente que apresentavam uma oclusão aparentemente normal e a linha média dentária superior coincidente com a linha média facial e com a inferior. Cada fotografia real foi manipulada com auxílio do Adobe Photoshop 7.0, para obter-se fotografias com desvio de linha média superior de 1 a 4mm, totalizando 30 fotografias. Tais imagens foram analisadas por cirugiões-dentistas, alunos de odontologia e adolescentes leigos, os quais as classificaram levando em consideração a estética do sorriso. Para verificar a atratividade do sorriso foi utilizado a análise de variância (ANOVA) para a avaliação inter e intra-grupos, além da correlação de Pearson. Resultados: os grupos de alunos e cirurgiões-dentistas mostraram correlação negativa entre o desvio da linha media e a atratividade do sorriso (p≤0,05). Foi possível observar que não houve diferença estatisticamente significante na avaliação feita por adolescentes leigos independente do grau de desvio de linha média. Conclusão: desvios de linha média superior prejudicam a atratividade de sorriso quando avaliadas por pessoas que têm conhecimento sobre a área odontológica.
Abstract Introduction and objective: the analysis of the smile in the face of dental treatment is essential and must always take into account factors such as: age of the patient, anomalies in the size and shape of the teeth, face shape, lips, color, presence of diastema, dental midline deviations, between others. To investigate the possible influence of the deviation of the upper midline on the attractiveness of the smile in adolescents. Materials and methods: six frontal photographs in posed smile were selected from orthodontically treated adolescent volunteers who had an apparently normal occlusion and an upper dental midline coincident with facial and lower midline. Each real photograph was manipulated with the aid of Adobe Photoshop 7.0, in order to obtain photographs with an upper midline deviation of 1 to 4mm, totaling 30 photographs. Such images were analyzed by graduated dentists, dentistry students and lay adolescents, who classified them considering the aesthetics of the smile. To check the attractiveness of the smile, analysis of variance (ANOVA) was used for inter and intra-group evaluation, in addition to Pearson's correlation. Results: the groups of students and dentists showed a negative correlation between the deviation from the midline and the attractiveness of the smile (p ≤0.05). It was possible to observe that there was no statistically significant difference in the assessment made by lay adolescents, regardless of the degree of deviation from the midline. Conclusion: deviations from the upper midline impair the smile attractiveness when evaluated by people who are knowledgeable about the dental field.
Resumen Introducción y objetivo: el análisis de la sonrisa de cara al tratamiento odontológico es fundamental y siempre debe tener en cuenta factores como: edad del paciente, anomalías en el tamaño y forma de los dientes, forma de la cara, labios, color, presencia de diastemas, desviaciones de la línea media, entre otros. Investigar la posible influencia de la desviación de la línea media superior en el atractivo de la sonrisa en adolescentes. Materiales y métodos: se utilizaron seis fotografías frontales en sonrisa posada tomadas a adolescentes voluntarios tratados con ortodoncia que tenían oclusión aparentemente normal y línea media dentaria superior coincidente con línea media facial e inferior. Cada fotografía real fue manipulada con la ayuda de Adobe Photoshop 7.0, con el fin de obtener fotografías con una desviación de la línea media superior de 1 a 4 mm, totalizando 30 fotografías. Tales imágenes fueron analizadas por odontólogos graduados, estudiantes de odontología y adolescentes legos, quienes las clasificaron teniendo en cuenta la estética de la sonrisa. Para verificar el atractivo de la sonrisa, se utilizó el análisis de varianza (ANOVA) para la evaluación inter e intra-grupo, además de la correlación de Pearson. Resultados: los grupos de estudiantes y dentistas mostraron una correlación negativa entre la desviación de la línea media y el atractivo de la sonrisa (p ≤0.05). Se pudo observar que no hubo diferencia estadísticamente significativa en la evaluación realizada por los adolescentes legos independientemente del grado de desviación de la línea media. Conclusión: las desviaciones de la línea media superior perjudican el atractivo de la sonrisa cuando son evaluadas por personas que tienen conocimientos sobre el campo dental.
ABSTRACT
BACKGROUND: Health-related quality of life (HRQoL) is determined by multiple factors that include components such as spirituality and religiousness (S/R). Even though various systematic reviews have investigated the association between S/R and improved health outcomes in the most different groups, healthy young individuals are seldom addressed. OBJECTIVE: To assess the association between S/R and HRQoL among young, healthy individuals. METHODS: Systematic review of papers published in the last ten years and indexed in four academic research databases (PubMed, Web of Science, Cochrane Library, and Scopus) and two gray literature databases. Inclusion criteria were studies assessing S/R and HRQoL using validated instruments and assessing healthy adults (i.e., non-clinical patients, not belonging to any specific group of chronic diseases), aged between 18 and 64 years old. RESULTS: Ten out of 1,952 studies met the inclusion criteria: nine cross-sectional and one longitudinal cohort study, in which 89% of the participants were college students. Nine studies report a positive association between S/R and HRQoL, while one study did not report any significant association. The main HRQoL domains associated with S/R were the psychological, social relationships, and environment domains, while the S/R most influent facets/components were optimism, inner strength, peace, high control, hope, and happiness. CONCLUSIONS: Higher S/R levels among healthy adult individuals were associated with higher HRQoL levels, suggesting the S/R can be an important strategy to deal with adverse environmental situations even among those without chronic diseases, enhancing the wellbeing of individuals.

Although pain is a frequent complaint of patients with chronic kidney disease who undergo hemodialysis, few studies have assessed the functional interference of pain in activities of daily living (ADLs). Hence, the aim of this study was to evaluate the prevalence, location, intensity, and functional interference of pain in ADLs of chronic kidney disease patients undergoing hemodialysis and to estimate the association of specific pain sites with severe functional interference by pain in ADLs. This cross-sectional study included patients with chronic kidney disease undergoing hemodialysis. The prevalence, intensity, and functional interference of pain in ADLs were assessed using the brief pain inventory. Poisson regression was used to calculate the prevalence ratio. A total of 65 patients participated in the study. The overall prevalence of pain was 89.23%; the prevalence of headache was 18.46% and that of pain in the trunk was 55.38%, upper limbs was 35.38%, and lower limbs was 60.00%. The prevalence of moderate and severe pain at the time of hemodialysis was 13.85% and 21.54%, respectively. A high prevalence of severe functional interference of pain in general activity (61.54%), mobility (56.92%), and disposition (55.38%) was observed. Pain is a frequent complaint in patients undergoing hemodialysis, mainly musculoskeletal and intradialytic, and it interferes with ADLs and incapacitates the patient. Pain was highly prevalent in the upper and lower limbs and the trunk. Furthermore, a higher prevalence of severe pain at the time of hemodialysis and functional interference of pain, mainly in general activity, mobility, and disposition, were observed.
ABSTRACT
The aim of the present study was to evaluate whether the addition of red propolis extract (RPE), in different roughage: concentrate (R:C) ratios, influences the intake, digestibility, ruminal parameters, and serum biochemistry of sheep. We used eight Santa Inês sheep with an average body weight of 29.45 ± 1.58 kg, housed in metabolism cages for 60 days, and distributed in two simultaneous Latin square designs in a 2 × 2 factorial scheme. The factors consisted of two R:C ratios (70:30 and 30:70) with or without the addition of 15 mL/day of RPE. No interactions were found (P > 0.05) between R:C ratios and with or without RPE. Sheep fed 30:70 ratio showed higher (P < 0.05) intake and dry matter (DM) digestibility and non-fibrous carbohydrates and lower (P < 0.05) intake and neutral detergent fiber (NDF) digestibility. The addition of RPE did not influence (P > 0.05) the intake or nutrients digestibility, but the sheep that received RPE had a higher (P < 0.05) ruminal pH and longer (P < 0.05) time of rumination (min/kg DM) compared to the group without propolis. The ruminal ammonia concentration was higher for sheep fed 70:30 ratio, but the concentrations of total protein and albumin did not differ between R:C ratios. The addition of 15 mL of RPE does not influence the intake, digestibility, ingestive behavior, and rumen ammonical nitrogen of sheep. There is no association between the R:C ratio and the addition of 15 mL/day of RPE for sheep.

Introdução: Grande proporção dos atos violentos praticados contra as mulheres resulta em lesões maxilofaciais. A região facial é o local mais recorrente das violências físicas, uma vez que o violentador deseja evidenciar a fragilidade da vítima e distanciá-la socialmente, causando danos psicológicos, estéticos e morais. Objetivo: Analisar as regiões craniofaciais mais afetadas e o perfil das mulheres que sofreram violência não fatal. Método: Trata-se de uma revisão integrativa da literatura, com identificação de artigos nas bases SciELO, MEDLINE via PubMed, LILACS e BBO, usando os descritores "violência doméstica", "injúria facial", "traumatismo facial" e suas variantes nos idiomas inglês e português. Resultados: Foram selecionados 14 estudos. A idade das mulheres variou de 16 a 64 anos, com a maioria tendo ocupações domésticas e dependência financeira do cônjuge ou parceiro. Todos os estudos abordavam a região de cabeça e pescoço como o local mais acometido por lesões, por se tratar de uma região vulnerável. A órbita foi considerada a estrutura anatômica mais acometida mencionada em quatro estudos, seguida por boca, nariz e mandíbula. Hematomas e equimoses foram as lesões mais encontradas, identificadas em 9 estudos. Além disso, 13 estudos relataram o uso de instrumento contundente durante as agressões. Outras lesões como fraturas dentais, avulsão dentária, fraturas faciais e edema foram encontradas com menos frequência. Conclusão: O terço superior da face foi o mais atingido, em especial a órbita, e o tipo de injúria mais comum foram as equimoses e hematomas geralmente provocados pelos parceiros.
Introduction: A large proportion of violent acts against women result in maxillofacial injuries. The facial region is the most recurrent site of physical violence because the abuser wishes to highlight the victim's frailty and distance it socially, causing psychological, aesthetic and moral damage. Objective: To analyze the most affected craniofacial regions and the profile of women who have suffered non-fatal violence. Method: This is an integrative literature review, with identification of articles in SciELO, MEDLINE/ PubMed, LILACS and BBO, using the keywords "domestic violence", "facial injury", "facial trauma" and its variants in English and Portuguese. Results: 14 studies were selected. The age of the women ranged from 16 to 64 years, with the majority having domestic occupations and financial dependence on their spouse or partner. All studies mentioned the head and neck region as the location most affected by injuries, as it is a vulnerable region. The orbit was the most affected anatomical structure mentioned in four studies, followed by the mouth, nose and mandible. Bruises were the most frequently found lesions, identified in nine studies. In addition, 13 studies reported the use of a blunt instrument during attacks. Other injuries such as dental fractures, tooth avulsion, facial fractures and edema were found less frequently. Conclusion: The upper third of the face was the most affected, especially the orbit, and the most common type of injury was bruises usually caused by partners
