Abstract
Three-dimensional printing technologies can be implemented for the fabrication of personalized vaginal rings (VRs) as an alternative approach to traditional manufacturing. Although several studies have demonstrated the potential of additive manufacturing, there is a lack of knowledge concerning the opinions of patients and clinicians. This study aimed to investigate the perception of women and gynecologists regarding VRs with personalized shapes. The devices were printed with different designs (traditional, "Y", "M", and flat circle) by Fused Deposition Modeling for a cross-sectional survey with 155 participants. Their anticipated opinion was assessed through a questionnaire after a visual/tactile analysis of the VRs. The findings revealed that most women would feel comfortable using some of the 3D-printed VR designs and demonstrated good acceptability for the traditional and two innovative designs. However, women presented multiple preferences when the actual geometry was assessed, which directly related to their age, previous use of the vaginal route, and perception of comfort. In turn, gynecologists favored prescribing traditional and flat circle designs. Overall, although there was a difference in the perception between women and gynecologists, they had a positive opinion of the 3D-printed VRs. Finally, the personalized VRs could lead to an increase in therapeutic adherence, by meeting women's preferences.

Abstract
STUDY DESIGN A primary, observational, cross-sectional, analytical study. OBJECTIVE The development of a framework for systematic telemedicine (TM) for orthopedic physicians in frequent clinical care may increase agreement in diagnosis and satisfaction among users of TM. Therefore, this study aimed to estimate the agreement in the diagnosis of low back pain (LBP) between TM, systematized by a self-completed digital questionnaire, and face-to-face (FF) care in patients with LBP. METHODS This study included adults up to 75 years of age with LBP for more than 6 weeks. They were evaluated at 2 independent time points (TM and FF) by different orthopedists with 3 different levels of expertise. Professionals evaluated the sample without prior knowledge of the diagnosis, and each orthopedist provided a diagnosis. Diagnostic agreement was the primary outcome. Secondary outcomes were the duration of the visit and satisfaction among healthcare professionals. RESULTS A total of 168 participants were eligible, of whom 126 sought care through TM and 122 sought FF care (mean age, 47 years [range, 18-75 years]; 66.4% women). The agreement among professionals regarding the diagnosis was moderate (kappa = .585, P = .001). TM was faster than FF (11.9 minutes (standard deviation = 4.1) vs 18.6 (SD = 6.9), P < .001). Professional satisfaction was higher among spine specialists than among orthopedic residents and orthopedists who were not specialists in spine surgery. CONCLUSION Agreement in diagnosis was moderate for TM, with a 30% shorter visit duration than FF. Satisfaction varied by professional expertise and was higher among spine specialists than among professionals with other expertise.

Abstract
INTRODUCTION Fibromyalgia is a polysymptomatic syndrome with a prevalence between 0.2% and 13% of the population and causes work disabilities in approximately half of affected patients. Several treatments to fibromyalgia have been proposed with partial improvement. This study aims to evaluate the efficacy of hyperbaric oxygen therapy and when it should be introduced to fibromyalgia. METHODS AND ANALYSIS This is a protocol for an open-label, crossover, randomised clinical trial comparing treatment with hyperbaric oxygen therapy and standardised treatment to fibromyalgia. In the proposed study, 56 individuals with fibromyalgia will be randomised in a 1:1 ratio into a single, fixed, random block, in which one group will receive hyperbaric oxygen therapy and another will receive standard treatment. Subsequently, the groups will be crossed. Participants will be evaluated at baseline, eight and 16 weeks based on functional impairment assessed with the Fibromyalgia Impact Questionnaire-Brazilian Portuguese version, psychopathological symptoms questionnaire and short-form quality of life questionnaire. The improvement of symptoms concerning the moment of therapy used will be compared between groups. For sample size calculation, a moderate effect size, 80% power and 95% CI will be estimated, in a total of 46 patients. Considering a dropout of 20%, 56 patients should be recruited. ETHICS AND DISSEMINATION The study was approved by the Universidade Federal de Juiz de Fora Teaching Hospital ethics committee and assigned the number 53058421.9.0000.5133 (version 3). The results will be disseminated via publications in peer-reviewed journals and presentations in medical meetings. TRIAL REGISTRATION NUMBER RBR-6prps8g)/UTN U1111-1278-3224.

Abstract
Fibromyalgia (FM) is an idiopathic disorder characterized by generalized pain and associated symptoms such as depression and anxiety. Cannabis sativa shows different pharmacological activities, such as analgesic, anti-inflammatory, neuroprotective, and immunomodulatory. Associated with this, the use of an oil with low concentrations of THC can reduce the psychomimetic adverse effects of the plant. Therefore, the present study aimed to evaluate the analgesic effect of broad-spectrum cannabis oil with low THC concentration in an experimental model of FM. Mechanical hyperalgesia, thermal allodynia, depressive- and anxious-related behavior, and locomotor activity were evaluated after reserpine (0.25 mg/kg; injected subcutaneously (s.c.) once daily for three consecutive days) administration. Our results showed that oral administration of broad-spectrum cannabis oil (0.1, 1, and 3 mg/kg, p.o.) in a single dose on the 4th day inhibited mechanical hyperalgesia and thermal allodynia induced by reserpine. Relevantly, treatment during four days with broad-spectrum cannabis oil (0.1 mg/kg, p.o.) reduced mechanical hyperalgesia 1 h after reserpine administration. Intraplantar treatment with cannabis oil significantly reversed mechanical and heat thermal nociception induced by reserpine injection. Interestingly, spinal and supraspinal administration of broad-spectrum cannabis oil completely inhibited mechanical hyperalgesia and thermal sensitivity induced by reserpine. The repeated cannabis oil administration, given daily for 14 days, markedly mitigated the mechanical and thermal sensitivity during the FM model, and its reduced depressive-like behavior induced by reserpine. In summary, broad-spectrum cannabis oil is an effective alternative to reverse the reserpine-induced fibromyalgia model.

Abstract
BACKGROUND Hypovitaminosis D is a public health problem associated with several chronic inflammatory and immunological diseases, including psoriasis. OBJECTIVES This study aimed to determine the prevalence of hypovitaminosis D in patients with plaque psoriasis. A comparison was made between vitamin D levels in patients with psoriasis and those with other non-inflammatory dermatoses without photosensitivity. In addition, it evaluated the effects of the patients' Fitzpatrick skin phototype and the season of the year on the serum levels of vitamin D. DESIGN AND SETTINGS A retrospective cross-sectional study was conducted at an outpatient clinic in a university center in Juiz de Fora (MG), Brazil. METHODS A review of dermatology patients' demographic data, including skin phototype and serum levels of 25-hydroxyvitamin D [25(OH)D], over 12 months in 2016. RESULTS This study included 554 patients: 300 patients allocated to the plaque psoriasis group and 254 control patients with other dermatological diseases. Regarding the season of the year, 229, 132, 62, and 131 participants were evaluated in summer, autumn, winter, and spring, respectively. As for the skin phototype, 397, 139, and 18 patients had phototypes III, IV, and V, respectively. The serum levels of 25(OH)D were significantly lower in the psoriasis group (24.91 ± 7.16 ng/mL) than in the control group (30.37 ± 8.14 ng/mL). CONCLUSIONS Hypovitaminosis D (< 30 ng/mL) was present in 76.66% of patients with psoriasis versus 53.94% of control patients. Vitamin D deficiency (< 20 ng/mL) was observed in 25% of the patients with psoriasis versus 8.66% in the control group (P < 0.001). The season and patient's skin phototype were independent predictors of serum vitamin D levels.

Abstract
BACKGROUND Psoriasis is a systemic, immune-mediated disease characterized by inflammatory manifestations in the skin and joints. Vitamin D deficiency is currently considered a pandemic and is associated with comorbidities including psoriasis and psoriatic arthritis (PsA). OBJECTIVES To determine the prevalence of hypovitaminosis D [25(OH)D] in patients with plaque psoriasis, with and without PsA, and of independent predictors of serum 25(OH)D levels. DESIGN AND SETTING Retrospective cross-sectional study conducted among 300 patients at an outpatient clinic in a university center in Juiz de Fora, Minas Gerais, Brazil. METHODS Demographic and clinical data (psoriasis area and severity index [PASI], family history, age at onset, disease duration, and the presence of PsA according to Classification Criteria for Psoriatic Arthritis), skin phototype, and season of the year were reviewed. RESULTS Hypovitaminosis D (< 30 ng/mL) was highly prevalent in patients with psoriasis with and without PsA (82.2% and 74.9%, respectively). An inverse correlation between PASI and vitamin D was found (without PsA r = -0.59 and, PsA r = -0.52, P < 0.001), and multivariate regression revealed that hypovitaminosis D was associated with disease severity, season, and phototype. It was confirmed by binary logistic regression between PASI and vitamin D deficiency (< 30 ng/mL), (odds ratio, OR 1.78 CI: -0.20-0.53, P < 0.001). CONCLUSION Hypovitaminosis D (< 30 ng/mL) was highly prevalent in psoriatic patients with and without PsA. Season and skin phototype were associated with 25(OH)D levels. An inverse association between PASI and serum 25(OH)D levels was established.

Abstract
Rosmarinic acid (RA), an ester of caffeic acid and 3, 4-dihydroxyphenyllactic acid, has anti-inflammatory and neuroprotective activities. Herein, this study investigated in silico the drug-likeness and the potential molecular targets to RA. Moreover, it tested the antidepressant-like potential of RA in the lipopolysaccharide (LPS)-induced depression model. RA (MW = 360.31 g/mol) meets the criteria of both Lipinski's rule of five and the Ghose filter. It also attends to relevant pharmacokinetic parameters. Target prediction analysis identified RA's potential targets and biological activities, including the peroxisome proliferator-activated receptor (PPAR) and the cannabinoid receptors CB1 and CB2 . In vivo, RA's acute, repetitive, and therapeutic administration showed antidepressant-like effect since it significantly reduced the immobility time in the tail suspension test and increased grooming time in the splash test. Further, the pretreatment with antagonists of CB1 , CB2 , and PPAR-γ receptors significantly blocked the antidepressant-like effect of RA. Altogether, our findings suggest that cannabinoid receptors/PPAR-γ signaling pathways are involved with the antidepressant-like effect of RA. Moreover, this molecule meets important physicochemical and pharmacokinetic parameters that favor its bioavailability. RA constitutes a promising, innovative, and safe molecule for the pharmacotherapy of major depressive disorder.

Abstract
Background: Posttraumatic stress disorder (PTSD) is a psychiatric condition that manifests through a broad range of symptoms and shares several phenotypes with anxiety and depression. Refractory PTSD affects 10 – 30% of the patients and highlights the need for alternative pharmacotherapy. The suggested involvement of the endocannabinoid system (ECS) with the emotional processes has enlightened the use of Cannabis sp. Then, this study aimed to evaluate the therapeutic effects of a broad-spectrum Cannabis oil on anxiety- and depressive-like behaviors triggered by stressors from combined nature. In addition, this study investigated the effect of the oil on central cannabinoid receptor 1 and serum levels of cytokines, chemokines, and growth factors. Methods: Mice were randomized into five groups (vehicle; Cannabis oil; fluoxetine; single oral dose) and submitted to acute restraint and chronic unpredictable stress. Then, they were behaviorally assessed in the elevated plus-maze test (EPMT), forced swimming test (FST), splash test (ST), and open field test (OFT). The tetrad cannabinoid assay evaluated the central effect of the oil. Serum biomarkers levels were measured by a multiplex bead-based assay. Results: Cannabis oil (0.1 mg/kg, p.o.) significantly reduced the anxiety-like behavior in EPMT in the acute restraint stress model (p < 0.05) as compared to vehicle. Moreover, compared to the vehicle, Cannabis oil significantly reverted the despair and anhedonic-like behaviors in FST (p < 0.05) and ST (p < 0.05), respectively, in chronically stressed mice. Yet, compared to vehicle, therapy with Cannabis oil did not induce cannabinoid-tetrad (p < 0.0001); downregulated granulocyte-macrophage colony-stimulating factor (GM-CSF; p < 0.01) and advanced glycation end-products (RAGE; p < 0.0001); and upregulated vascular endothelial growth factor (VEGF; p < 0.01) serum levels. Conclusion: Altogether, our data suggest the potential of the broad-spectrum Cannabis oil to improve symptoms related to anxiety and depression caused by traumatic events.

Abstract
BACKGROUND Psoriatic arthritis is the most frequent and impactful comorbidity among psoriatic patients and appears in most cases after skin disease. Dermatologists play a key role in its early diagnosis and treatment. OBJECTIVE To determine the prevalence of psoriatic arthritis and associated variables among patients with plaque psoriasis seen at a reference center for treating psoriasis. DESIGN AND SETTING Retrospective cross-sectional study conducted among 300 patients at an outpatient clinic in a university center in Juiz de Fora, MG, Brazil. METHODS Standardized records of 300 patients with plaque psoriasis were examined. Demographic data and medical variables relating to psoriasis (Psoriasis Area and Severity Index (PASI), family history, age at onset and disease progression) and psoriasis arthritis (CASPAR criteria) were evaluated. Laboratory and radiographic tests in the medical records were reviewed. RESULTS Seventy-three (24.3%) of these 300 patients with plaque psoriasis had psoriatic arthritis. Asymmetric oligoarthritis (58.9%) was the most common clinical form, followed by polyarthritis (20.5%), distal interphalangeal arthritis (15.2%) and spondyloarthritis (5.4%). Dactylitis was present in 21.9% and enthesitis in 35.6% of patients. Compared with patients without arthritis, patients with arthritis had higher average age, higher frequency of positive family history of psoriasis, longer duration of evolution and higher PASI rates. CONCLUSION Psoriatic arthritis is often underdiagnosed. Since dermatologists perform the initial approach, these professionals need to be trained to diagnose this comorbidity and treat it, together with rheumatologists.

Abstract
Aim: To isolate licochalcone A (LicoA) from licorice, prepare LicoA-loaded solid lipid nanoparticles (L-SLNs) and evaluate the L-SLNs in vitro and in vivo against Schistosoma mansoni. Materials & methods: LicoA was obtained by chromatographic fractionation and encapsulated in SLNs by a modified high shear homogenization method. Results: L-SLNs showed high encapsulation efficiency, with satisfactory particle size, polydispersity index and Zeta potential. Transmission electron microscopy revealed that L-SLNs were rounded and homogenously distributed. Toxicity studies revealed that SLNs decreased the hemolytic and cytotoxic properties of LicoA. Treatment with L-SLNs showed in vivo efficacy against S. mansoni. Conclusion: L-SLNs are efficient in reducing worm burden and SLNs may be a promising delivery system for LicoA to treat S. mansoni infections.

Abstract
PURPOSE We aimed at verifying whether resveratrol can decrease cell proliferation and change osteogenic differentiation of cells obtained from patients with type 1 neurofibromatosis (NF1). METHODS Deciduous dental pulp derived stem cells were isolated from NF1 patient and healthy volunteer. These cells were subjected to increasing concentrations of resveratrol and evaluated for proliferation and mineralization of osteogenic differentiation. RESULTS The results showed that resveratrol reduced the difference in proliferation between CNT and NF1 cells in a dose-dependent manner and this property was more prominent in affected cells than in healthy cells. Resveratrol showed no statistically significant changes in mineralization in osteogenic differentiation of NF1 cells, at low doses tested. CONCLUSIONS In conclusion, in a dose-dependent manner, resveratrol displays interesting properties that could be applied in a possible treatment aimed at decreasing cellular proliferation in neurofibromatosis. Furthermore, it is selective concerning healthy cells and not affecting cell differentiation. Further research to cell selectivity, differentiation to other tissue types, and cell cytotoxicity are needed.

Abstract
OBJECTIVE To investigate the association between genetic polymorphisms in candidate genes or candidate regions and the development of endometriosis in Brazilian women. METHODS A total of 30 women between 25 and 64 years old with a diagnosis of endometriosis participated in the present study, as well as 30 matched control women from the same age group, asymptomatic and without family history of the disease. The patients genotypic and allelic frequencies of polymorphisms in the GREB1 gene (rs13394619) and in the intergenic region at position 7p15.2 (rs12700667) were analyzed and compared. RESULTS There was no significant difference in the frequency of genotypes for the A > G polymorphism (rs13394619) in the GREB1 gene between the two groups. However, the distribution frequencies of the genotypes for the A > G polymorphism (rs12700667) in an intergenic region on chromosome 7 were different for control patients and for patients with endometriosis, with higher frequency of the AG genotype compared to the GG between patients with the disease (odds ratio [OR] = 3.49; confidence interval [CI] = 1.47-8.26). CONCLUSION The present study suggests that the polymorphism in the intergenic region of chromosome 7 is associated with the risk of developing endometriosis in a population of Brazilian women from Juiz de Fora.

Abstract
Jaboticaba, Plinia cauliflora (Mart.) Kausel, is a Brazilian berry traditionally used in folk medicine as treatment for some health conditions. Phenolic compounds such as flavonoids and anthocyanins have previously been detected in the fruit. This current study aimed to evaluate the toxicological effects of jaboticaba peel extract (JPE) on Artemia salina, L929, and MDA-MB-231 cell lines. Besides, JPE antioxidant, acetylcholinesterase, and antifungal activities, and elemental analysis CHNS were also tested. JPE had moderate toxicity (LD50 = 360.92 μg mL-1) on A. salina, non-toxic effect on L929 cell line, and decreased the viability of cancer cell line MDA at 1,000 µg mL-1 and 500 µg mL-1 concentrations. The antioxidant activity toward 2,2-diphenyl-1-picrylhydrazyl (DPPH) performed IC50 = 37.45 ± 0.17 µg mL-1, whereas 45.7% of acetylcholinesterase activity was inhibited. By its elemental composition, JPE is an alternative food supplement and dermocosmetic component. Antifungal potential toward Candida strains was not observed.

Abstract
OBJECTIVE Organic silicon has been linked to positive effects on the skin rejuvenation, mainly by the oral route. Thus, the main objective of the present study was to assess whether monomethylsilanetriol (MMST, a source of organic silicon) can deliver silicon to the epidermis and dermis, when applied topically in a cream. Once the hypothesis was confirmed, the present study also evaluated whether the product was toxic to keratinocytes; additionally, its possible antioxidant activity was assessed. METHODS The ex vivo skin permeation profile was determined using human skin in Franz-cells equipment; cytotoxicity was assessed using HaCaT keratinocytes. Antioxidant capacity was determined as scavenging activity, measured according to the 1,1-diphenyl-2-picrylhydrazil free radical method. RESULTS The permeation percentage was almost 60% of the applied MMST, with a large quantity of drug found in the viable epidermis and dermis. The cell viability assay showed no significant difference in the percentage of viable keratinocytes among the treated groups at the doses used. In terms of antioxidant activity, the IC50 value obtained was 2400 μg mL-1 . Low antioxidant activity, negligible toxicity for keratinocytes and a significant percentage of permeation were observed. CONCLUSION We provide evidence that MMST applied topically can deliver silicon to the skin in biorelevant levels for cosmetic purposes.

Abstract
Halitosis can be described as unpleasant odors emanating from the oral cavity. It is usually associated with decomposition action of bacteria present mainly on the back of the tongue and periodontal pockets, and able to produce volatile sulfur compounds. We conducted a study at the Faculty of Dentistry, Federal University of Juiz de Fora and evaluated the therapeutic effect of two natural extracts, Camellia sinensis (green tea) and resveratrol in the form of oral polymer films, to control halitosis. Fifty volunteers (students of health courses) participated in the research after orientation and signing the informed consent form. The anamnesis was made by researchers. The physical examination was made to verify the inclusion criteria. Each participant received 45 polymeric films to be consumed in 15 days (3 films per day). Measurements of the volatile sulfur compound levels were performed using a halimeter in two stages: 1) before use and 2) 15 days after the first administration. Results showed a statistically significant reduction in volatile sulfur compound levels in 71.79% of the volunteers. We concluded that the compounded orodispersible films containing green tea and resveratrol demonstrated excellent results in reducing halitosis.

Abstract
In the 1990s, the development of microelectronics and communication technologies spawned the information technology paradigm, characterized by an intensity of information which, transformed into knowledge and innovation, plays a crucial role for development. In order for this to occur, countries need to build appropriate institutional arrangements. This led to the Triple Helix model for systems innovation, which views innovation and technical progress in a Knowledge Economy as the result of a complex set of relations between universities, companies, and government. In this context, the current study aims to identify the impact of knowledge production and public policies for the production of patent applications by life sciences and health sciences researchers affiliated with federal universities in the State of Minas Gerais, Brazil. The analysis covered the years 1995 to 2016 and used econometric techniques in panel data. According to the findings, educational factors (thesis supervision), economic factors (technological products and the provision of technological services), and political factors (legal framework, financial resources, and incentive policies) impact the production of patent applications by the selected researchers. The results reveal efforts by government, although incipient, in the attempt to promote a technological leap.

Abstract
Orodispersible film can be defined as a solid pharmaceutical form intended for the delivery and rapid local or systemic release of active ingredients, consisting of a water-soluble polymer film that hydrates rapidly, adhering and dissolving immediately when placed on the tongue or in the oral cavity (oral, palatal, gingival, lingual, or sublingual), without the need for water administration or mastication. Due to its outstanding importance in cases of emergency, practicality of use by patients in transit, and high adherence, orodispersible film has evolved in popularity and success among consumers. It is a promising dosage form for compounding pharmacies, as simpler technologies are being developed to make the compound process easier and faster for the pharmacist. This article aims to explore some of the basics on orodispersible film and the main possible preparations to be developed in compounding pharmacies worldwide.

Pharmacological advances in erectile dysfunction (ED) treatment have aroused growing interest among health professionals towards sexual dysfunction, generating an increasing demand for dosage forms and drug delivery systems, including tadalafil. This study aimed to develop a device to generate patches that would enable drug dosage individualization and transdermal administration. To create such a mechanical device, technical drawings were made using the CAD software. A functional prototype was built, and a pharmaceutical formulation containing tadalafil (10 mg cm-2) was prepared. An analytical method (HPLC) was developed and validated. The average weight of adhesives (n = 10) was 241.01 mg; the content uniformity for preparations in unit doses (n = 10) was 108.93%, and a CV <2% for intraadhesive tadalafil content (n = 40) was observed. The ex vivo permeation of patches containing tadalafil was determined in Franz cells (n = 6), equipped with human skin and kept for 12 h in contact with the patch, by using the tape stripping method. The optimized method showed acceptable confidence limits within the range recommended by regulatory agencies, being validated for use in this ex vivo permeation study. Tadalafil could permeate to the viable epidermis and dermis (5.7%). The created device produced homogeneous patches of tadalafil, showing such technological innovation as to be feasible in individualized therapy for the treatment of ED.

Abstract
O objetivo do presente estudo foi avaliar a eficácia ex vivo de um dentifrício dessensibilizante contendo biovidro (Sensodyne®Repair&Protect, GlaxoSmithKline Brasil Ltd., Rio de Janeiro, Brasil), quanto ao potencial de obliteração dos túbulos dentinários e compará-lo com os dentifrícios convencionais (Colgate® Sensitive Pro-Alívio™, Colgate-Palmolive, São Paulo, SP, Brasil eSensodyne® Rápido Alívio, GlaxoSmithKline Brasil Ltd., Rio de Janeiro, Brasil). Foram utilizados 12 pré-molares humanos divididos em: G1 (n=4) - escovação com Colgate®Sensitive Pró-Alívio; G2 (n=4) - escovação com Sensodyne® Rápido Alívio; e G3 (n=4) - escovação com Sensodyne®Repair&Protect. As amostras foram submetidas à simulação de escovação de um período de oito semanas, com duas escovações diárias e analisadas em microscopia eletrônica de varredura (MEV), quanto à presença e características dos túbulos dentinários; a espectroscopia de raios-X por dispersão em energia (EDS), a fim de avaliar os elementos químicos presentes nos túbulos dentinários. A análise qualitativa da obliteração dos túbulos dentinários foi avaliada por meio das fotomicrografias. Para verificar a distribuição normal dos dados da EDS, utilizou-se o teste de Shapiro-Wilk (p<0,05). De acordo com a normalidade apresentada, foram executados teste t-Studentde amostras pareadas e teste de Wilcoxon. No grupo G1 foi verificada diminuição na luz dos túbulos dentinários, enquanto no G2, além da diminuição dos túbulos, nítida deposição de partículas obliteradoras foi observada. No G3, foi detectada não só a obliteração dos túbulos, mas também a diminuição na quantidade dos mesmos; além da formação de uma camada de hidroxidocarbonato de apatita (HCA)sobre a dentina. A análise conjunta dos dados permitiu concluir que os dentifrícios testados foram capazes de ocluir os túbulos dentinários e que o dentifrício Sensodyne®Repair&Protect apresentou melhor eficácia na obliteração dos túbulos dentinários, seguido respectivamente dos dentifrícios Sensodyne® Rápido Alívioe Colgate®Sensitive Pró-Alívio.

Abstract
(−)-β-caryophyllene (BCP), a cannabinoid receptor type 2 (CB2)-selective phytocannabinoid, has already been shown in precedent literature to exhibit both anti-inflammatory and analgesic effects in mouse models of inflammatory and neuropathic pain. Herein, we endeavored to investigate the therapeutic potential of BCP on experimental autoimmune encephalomyelitis (EAE), a murine model of multiple sclerosis (MS). Furthermore, we sought to demonstrate some of the mechanisms that underlie the modulation BCP exerts on autoimmune activated T cells, the pro-inflammatory scenery of the central nervous system (CNS), and demyelination. Our findings demonstrate that BCP significantly ameliorates both the clinical and pathological parameters of EAE. In addition, data hereby presented indicates that mechanisms underlying BCP immunomodulatory effect seems to be linked to its ability to inhibit microglial cells, CD4+ and CD8+ T lymphocytes, as well as protein expression of pro-inflammatory cytokines. Furthermore, it diminished axonal demyelination and modulated Th1/Treg immune balance through the activation of CB2 receptor. Altogether, our study represents significant implications for clinical research and strongly supports the effectiveness of BCP as a novel molecule to target in the development of effective therapeutic agents for MS.

Abstract
Onychomycosis is a fungal infection of the nail caused by high densities of filamentous fungi and yeasts. Treatment for this illness is long-term, and recurrences are frequently detected. This study evaluated in vitro antifungal activities of 12 organic compounds derived from amino alcohols against standard fungal strains, such as Trichophyton rubrum CCT 5507 URM 1666, Trichophyton mentagrophytes ATCC 11481, and Candida albicans ATCC 10231. The antifungal compounds were synthesized from p-hydroxybenzaldehyde (4a–4f) and p-hydroxybenzoic acid (9a–9f). Minimum inhibitory concentrations and minimum fungicidal concentrations were determined according to Clinical and Laboratory Standards Institute protocols M38-A2, M27-A3, and M27-S4. The amine series 4b–4e, mainly 4c and 4e compounds, were effective against filamentous fungi and yeast (MIC from 7.8 to 312 μg/mL). On the other hand, the amide series (9a–9f) did not present inhibitory effect against fungi, except amide 9c, which demonstrated activity only against C. albicans. This allowed us to infer that the presence of amine group and intermediate carbon number (8C–11C) in its aliphatic side chain seems to be important for antifungal activity. Although these compounds present cytotoxic activity on macrophages J774, our results suggest that these aromatic compounds might constitute potential as leader molecules in the development of more effective and less toxic analogs that could have considerable implications for future therapies of onychomycosis.

Abstract
INTRODUCTION Nowadays it is described a high prevalence of hypovitaminosis D in Systemic Lupus Erythematosus (SLE), which is associated with some clinical manifestations and increased inflammatory activity. OBJECTIVE To evaluate the association between vitamin D insufficiency with SLE and inflammatory markers. METHODS Cross-sectional study, in which have been evaluated 45 SLE patients and 24 controls without the disease. Levels of 25-hydroxyvitamin D [25(OH) D] less than 30 ng/mL were considered inadequate. Disease activity was assessed by the Systemic Lupus Erythematosus Disease Activity Index (SLEDAI). High sensitivity C reactive protein (hsCRP) and interleukin-6 (IL-6) were evaluated for verification of the inflammatory status. For assessment of renal involvement, analysis of abnormal elements and urinay sediment (AES), quantitative hematuria and pyuria, proteinuria and creatinine clearance in 24-hour urine and serum anti-double stranded DNA were performed. RESULTS The prevalence of 25(OH)D insufficiency was 55% in SLE patients and 8% in the controls participants (p = 0.001). The median of 25(OH)D was lower in patients than in controls. Patients with insufficient 25(OH)D had higher levels of IL-6 and higher prevalence of hematuria in the AES. There was no correlation between vitamin D and SLEDAI or lupus nephritis. CONCLUSION In our study, vitamin D deficiency was more prevalent in patients with SLE and was associated with higher levels of IL-6 and hematuria.

Abstract
BACKGROUND Oxandrolone is a potent synthetic testosterone analogue that possesses strong anabolic property and weak androgenic activity. Apart of their clinical implicances, oral oxandrolone can potentially promote several adverse effects. It is known that the transdermal delivery of drugs may represent a means to avoid or minimize oral adverse effects Thus, the objective of this study was to evaluate the permeability of oxandrolone in human skin on a preliminary basis for possible future determination of the transdermal route as an alternative to oral treatments. METHODS We used a percutaneous absorption assay in Franz diffusion cells coupled with freshly excised human skin. The drug release kinetics were determined to predict the efficiency of this alternative route for the drug. RESULTS Nearly 236 μg (86.7%, in terms of applied dose) of the product was prevented to permeate due to the barrier function of the stratum corneum (SC); 21.6% reached the receptor medium (RM), and the remaining 4.3% were quantified within viable layers of the skin (in vivo, dermis is vascularized). The total amount of drug able to exert effect is the sum of the drug quantified within remained skin (RS) and RM: then, a total of 247.6 μg of oxandrolone (25.9% of the applied dose) would be able to permeate through a non damaged skin. The accuracy of the data is demonstrated by the calculated mass balance (average recovery = 112.6%). CONCLUSION Transdermal oxandrolone could be a viable alternative for traditional oral form, once clinical studies are conducted to prove this hypothesis.

Abstract
OBJECTIVE To confirm previous evidence suggesting an association between autism and low vitamin D serum levels. METHODS This preliminary exploratory study assessed the circulating levels of 25-hydroxyvitamin D (25-OHD) in pediatric patients with autism and in typically developing controls from Juiz de Fora, Brazil. RESULTS Serum levels of 25-OHD were lower in children with autism (26.48 ± 3.48 ng mL-1) when compared to typically developing subjects (40.52 ± 3.13 ng mL-1) (p < 0.001). CONCLUSION Our findings attest to the importance of vitamin supplementation during pregnancy and in the treatment of children with autism, who tend to present low vitamin D consumption rates.

Abstract
The aim of this study was to investigate the in vitro and in vivo efficacy and the tissue reaction of an antibiofilm coating composed of xylitol, triclosan, and polyhexamethylene biguanide. The antimicrobial activity was analyzed by a turbidimetric method. Scanning electron microscopy was used to evaluate the antiadherent property of central venous catheter (CVC) fragments impregnated with an antibiofilm coating (I-CVC) in comparison with noncoated CVC (NC-CVC) fragments. Two in vivo assays using subcutaneous implantation of NC-CVC and I-CVC fragments in the dorsal area of rats were performed. The first assay comprised hematological and microbiological analysis. The second assay evaluated tissue response by examining the inflammatory reactions after 7 and 21 days. The formulation displayed antimicrobial activity against all tested strains. A biofilm disaggregation with significant reduction of microorganism's adherence in I-CVC fragments was observed. In vivo antiadherence results demonstrated a reduction of early biofilm formation of Staphylococcus aureus ATCC 25923, mainly in an external surface of the I-CVC, in comparison with the NC-CVC. All animals displayed negative hemoculture. No significant tissue reaction was observed, indicating that the antibiofilm formulation could be considered biocompatible. The use of I-CVC could decrease the probability of development of localized or systemic infections.

Abstract
Glycogen synthase kinase-3B (GSK-3B) is involved with important neuronal processes such as cell survival, gene regulation, mood and cognitive performance. This enzyme is inactivated by phosphorylation at the phospho-Ser9 site. We compared GSK-3B levels in patients with schizophrenia to a health control group. The levels of phosphorylated and total GSK-3B in platelets of ten drug-free patients, ten long-term olanzapine treated patients and 20 healthy controls were determined by means of an enzyme immunoassay kit. In drug-free patients, GSK-3B levels were accessed again after 8 weeks on treatment with olanzapine. At baseline, drug-free patients presented lower phosphorylated and total GSK-3B levels than healthy controls (p < 0.05). After 8 weeks on olanzapine treatment, phosphorylated and total GSK-3B levels were significantly increased (p < 0.01). Reduced phospho-Ser9-GSK-3B in schizophrenia may disrupt signal-transduction pathways and influence crucial cellular processes, such as transcription, apoptosis, stress response and cell proliferation. Further studies should clarify whether the increment of GSK-3B phosphorylation by olanzapine is related to its antipsychotic effects.

Abstract
Background Due to high neutral lipids accumulation in the cytoplasm, in vitro-produced embryos from Bos primigenius indicus and their crosses are more sensitive to chilling and cryopreservation than those from Bos primigenius taurus. The objective of the present study was to evaluate the effects of trans-10, cis-12 conjugated linoleic acid (CLA) on the development and cryotolerance of crossbred Bos primigenius taurus x Bos primigenius indicus embryos produced in vitro, and cultured in the presence of fetal calf serum. Bovine zygotes (n = 1,692) were randomly assigned to one of the following treatment groups: 1) Control, zygotes cultured in Charles Rosenkrans 2 amino acid (CR2aa) medium (n = 815) or 2) CLA, zygotes cultured in CR2aa medium supplemented with 100 μmol/L of trans-10, cis-12 CLA (n = 877). Embryo development (cleavage and blastocyst rates evaluated at days 3 and 8 of culture, respectively), lipid content at morula stage (day 5) and blastocyst cryotolerance (re-expansion and hatching rates, evaluated 24 and 72 h post-thawing, respectively) were compared between groups. Additionally, selected mRNA transcripts were measured by Real–Time PCR in blastocyst stage. Results The CLA treatment had no effect on cleavage and blastocyst rates, or on mRNA levels for genes related to cellular stress and apoptosis. On the other hand, abundance of mRNA for the 1-acylglycerol-3-phosphate 0-acyltransferase-encoding gene (AGPAT), which is involved in triglycerides synthesis, and consequently neutral lipid content, were reduced by CLA treatment. A significant increase was observed in the re-expansion rate of embryos cultured with trans-10, cis-12 CLA when compared to control (56.3 vs. 34.4%, respectively, P = 0.002). However, this difference was not observed in the hatching rate (16.5 vs. 14.0%, respectively, P = 0.62). Conclusions The supplementation with trans-10, cis-12 CLA isomer in culture medium reduced the lipid content of in vitro produced bovine embryos by reducing the gene expression of 1-acylglycerol 3-phosphate 0-acyltransferase (AGPAT) enzyme. However, a possible improvement in embryo cryotolerance in response to CLA, as suggested by increased blastocyst re-expansion rate, was not confirmed by hatching rates.

Abstract
INTRODUCTION Ninety five percent of orthodontic patients routinely report pain, due to alterations in the periodontal ligament and surrounding soft tissues, with intensity and prevalence varying according to age. OBJECTIVE This study aimed to assess toothache and buccal mucosal pain in adults and children during two initial phases of the orthodontic treatment. METHODS The intensity of toothache and buccal mucosal pain reported by 20 patients, 10 children (11-13 years) and 10 adults (18-37 years) was recorded with the aid of a Visual Analog Scale (VAS), during 14 days--7 days with bonded brackets only and 7 days with the initial archwire inserted. RESULTS There was no significant difference in pain intensity among adults and children. After bracket bonding, 50% of the children and 70% of the adults reported pain. 70% of both groups reported pain after initial archwire insertion. While adults reported constant, low intensity, buccal mucosal pain, the children showed great variation of pain intensity, but with a trend towards decreasing pain during the assessment period. After initial archwire insertion the peaks of toothache intensity and prevalence occurred 24 hours in children and 48 hours in adults. CONCLUSIONS In general, children reported pain less frequently than adults did, though with greater intensity.

Abstract
OBJETIVO: Identificar os principais problemas de saúde, o perfil de utilização de medicamentos e os problemas relacionados aos medicamentos (PRMs) envolvidos no tratamento de idosos fragilizados da Zona da Mata Mineira. MÉTODOS: Foram avaliados prontuários de 260 idosos atendidos pelo Centro Mais Vida, Juiz de Fora-MG, entre agosto e setembro de 2010. As doenças foram agrupadas de acordo com a Classificação Internacional de Doenças - 10ª revisão, os medicamentos de acordo com o Anatomical Therapeutic Chemical Classification System e os PRMs de acordo com o Método Dáder. RESULTADOS: Observou-se que 73,8% dos idosos eram do sexo feminino e 42,7% possuíam entre 60 e 69 anos. Foram constatadas 1.300 doenças, sendo 31,07% do aparelho circulatório, 19,85% endócrinas, nutricionais e metabólicas e 13,46% do sistema osteomuscular e tecido conjuntivo. Dos 1.737 medicamentos, os mais prevalentes foram os do sistema cardiovascular (42,8%), seguidos pelos do trato alimentar e metabolismo (23,7%) e pelos do sistema nervoso (18,2%). Do total de medicamentos, 53,9% apresentaram algum PRM, sendo o PRM 1 (não utilização da medicação necessária) o mais frequente (37,4%). CONCLUSÃO: Os resultados evidenciam a necessidade da revisão dos esquemas terapêuticos dos idosos, visando o uso racional e efetivo dos medicamentos. Os dados apontam, ainda, a necessidade de aprofundar estudos de avaliação de riscos de PRM nessa população.

Abstract
Cellulose nanofibers (CNF) have mechanical properties that make them very attractive for applications in the construction of polymeric matrices, drug delivery and tissue engineering. However, little is known about their impact on mammalian cells. The objective of this study was to evaluate the cytotoxicity of CNF and their effect on gene expression of fibroblasts cultured in vitro. The morphology of CNF was analyzed by transmission electron microscopy and the surface charge by Zeta potential. Cell viability was analyzed by flow cytometry assay and gene expression of biomarkers focused on cell stress response such as Heat shock protein 70.1 (HSP70.1) and Peroxiredoxin 1 (PRDX1) and apoptosis as B-cell leukemia (BCL-2) and BCL-2 associated X protein (BAX) by RT-PCR assay. Low concentrations of CNF (0.02-100 μg ml(-1)) did not cause cell death; however, at concentrations above 200 μg ml(-1), the nanofibers significantly decreased cell viability (86.41 ± 5.37%). The exposure to high concentrations of CNF (2000 and 5000 μg ml(-1)) resulted in increased HSP70.1, PRDX1 and BAX gene expression. The current study concludes that, under the conditions tested, high concentrations (2000 and 5000 μg ml(-1)) of CNF cause decreased cell viability and affect the expression of stress- and apoptosis-associated molecular markers.

Abstract
In order to treat hyperpigmentation-related problems, there has been a global trend in developing cosmetics claiming to have skin-whitening properties, which act by inhibiting melanin biosynthesis. The objective of this work was to evaluate the in vitro mushroom tyrosinase inhibitory activity of five Amazonian native flora oils, and so to verify the possibility of their incorporation into cosmetic products. In addition, the fatty acid composition of the essential oils was determined by gas chromatography-flame ionisation detection in order to determine the main components of these oils. The tyrosinase inhibitory activity of the tested oils was found to be in the following order: açaí (IA50 = 66.08 µg mL-1) > tucumã > patauá > pracaxi > castanha do Brasil. This study suggests that açaí oil has great potential in the treatment of hyperpigmentation and other related disorders, due to its considerable tyrosinase inhibitory activity.

Abstract
Data on the prevalence of disabling hearing loss (DHL) in Brazil is scarce, which impacts healthcare professionals' knowledge on the extent of the problem. Objectives: This study aimed at estimating DHL prevalence in the municipality of Juiz de Fora, Minas Gerais, to identify individual-related variables and find risk areas. Materials and Methods: This was a descriptive sectional population study held from January to October of 2009. We randomly selected 349 households with 1,050 individuals who with ages ranging between 4 days and 95 years. The data collection instruments were: WHO structured questionnaire, ENT examination and laboratory tests. Chi-square and Poisson regression models were used for analyses. Results: DHL prevalence was estimated at 5.2% (95% CI = 3.1 to 7.3) which was classified as moderate in 3.9% (95% CI = 0.001 to 0.134), severe in 0.9% (95% CI = 0.001 to 0.107) and profound in 0.4% (95% CI = 0.001 to 0.095). We found correlation between DHL and tinnitus; age over 60 years and low educational level. Conclusions: Our data obtained pointed to the need to create hearing health programs targeted to specific risk groups, promoting quality of life for hearing impaired patients.

Abstract
INTRODUCTION: Since the emergence of antiretroviral therapy, the survival of patients infected with human immunodeficiency virus has increased. Non-adherence to this therapy is directly related to treatment failure, which allows the emergence of resistant viral strains. METHODS: A retrospective descriptive study of the antiretroviral dispensing records of 229 patients from the Center for Health Care, University Hospital, Federal University of Juiz de Fora, Brazil, was conducted between January and December 2009. RESULTS: The study aimed to evaluate patient compliance and determine if there was an association between non-adherence and the therapy. Among these patients, 63.8% were men with an average age of 44.0 ± 9.9 years. The most used treatment was a combination of 2 nucleoside reverse transcriptase inhibitors with 1 non-nucleoside reverse transcriptase inhibitor (55.5%) or with 2 protease inhibitors (28.8%). It was found that patients taking lopinavir/ritonavir with zidovudine and lamivudine had a greater frequency of inadequate treatment than those taking atazanavir with zidovudine and lamivudine (85% and 83.3%, respectively). Moreover, when the combination of zidovudine/ lamivudine was used, the patients were less compliant (χ2 = 4.468, 1 degree of freedom, p = 0.035). CONCLUSIONS: The majority of patients failed to correctly adhere to their treatment; therefore, it is necessary to implement strategies that lead to improved compliance, thus ensuring therapeutic efficacy and increased patient survival.
