RESUMO
The bimodal preference is a fourth diurnal preference proposed by re-scoring the Morningness-Eveningness Questionnaire. The present work aimed to describe the prevalence of the bimodal preference in a sample of undergraduate students and to characterize the bimodal type in terms of their health and sleep-related outcomes. A web-based cross-sectional study conducted between September 2018 and March 2021 (convenience sampling method). The sample was composed of undergraduate students who completed an electronic form that included the Morningness and Eveningness Questionnaire, the Pittsburgh Sleep Quality Index, the Self-Compassion Scale, the Epworth Sleepiness Scale, the Hospital Anxiety and Depression Scale, and the World Health Organization Subjective Well-Being Index. The final sample consisted of 615 students (82% female, mean age: 23.4 ± 6.5 years), of whom 108 (18%) had positive bimodality indexes. Bimodal subjects comprised 48 students, 8% of the total sample. Bimodal subjects had poorer subjective sleep quality, more daytime sleepiness, lower subjective well-being, greater anxiety and depression symptoms, and lower self-compassion than morning and/or intermediate types; they did not differ from evening types. The description of bimodal diurnal preference in this population may be of interest for the design of academic policies more in line with the circadian reality of students.

Microcystin (MC) is most common cyanobacterial toxin. Few studies have evaluated the MC effects on the hypothalamic-pituitary-gonadal (HPG) axis and metabolic function. In this study, we assessed whether MC exposure results in HPG axis and metabolic changes. Female rats were exposed to a single dose of MC at environmentally relevant levels (5, 20 and 40 µg/kg). After 24 h, we evaluated reproductive and metabolic parameters for 15 days. MC reduced the hypothalamic GnRH protein expression, increased the pituitary protein expression of GnRHr and IL-6. MC reduced LH levels and increased FSH levels. MC reduced the primary follicles, increased the corpora lutea, elevated levels of anti-Müllerian hormone (AMH) and progesterone, and decreased estrogen levels. MC increased ovarian VEGFr, LHr, AMH, ED1, IL-6 and Gp91-phox protein expression. MC increased uterine area and reduced endometrial gland number. A blunted estrogen-negative feedback was observed in MC rats after ovariectomy, with no changes in LH levels compared to intact MC rats. Therefore, these data suggest that a MC leads to abnormal HPG axis function in female rats.

BACKGROUND: Spinal manipulative therapy (SMT) demonstrates small effects on pain intensity in low back pain. Combining SMT with a psychosocial intervention like pain neuroscience education (PNE) could promote additional effect. OBJECTIVES: To evaluate the additional effect of PNE when combined to SMT on pain intensity and low back pain-related disability in patients with chronic low back pain (CLBP). METHOD: One hundred and four patients with CLBP of both sexes aged between 18 and 55 years were treated with PNE + SMT compared to SMT alone. The primary outcome measures were pain intensity and disability post-treatment (4 weeks). Secondary outcomes were fear-avoidance beliefs, global perceived effect of improvement, and pain self-efficacy. Results were obtained immediately post-treatment and at three follow-ups (30-days, 90-days, and 180-days). RESULTS: No significant between-group difference was observed for pain intensity and disability post-treatment. In contrast, our results showed a significantly longer additional effect for the group treated with SMT + PNE for the following outcomes: pain intensity (change baseline to 90 day follow-up = -0.90 [95% CI= -1.76, -0.4] and change baseline to 180 day follow-up = -1.19 [95% CI= -2.06, -0.32]) and low back pain-related disability, global perceived effect of improvement and pain self-efficacy (180th day follow-up). CONCLUSION: The results of this trial suggest the addition of PNE to SMT did not bring any additional effect on pain intensity and disability in the short term, but SMT + PNE can result in longer-lasting effects in patients with CLBP and that such an effect could be related to a possible mediator effect of pain self-efficacy.

This study investigated whether the origin of sperm (epididymal vs. ejaculate) affects the cryopreservation efficiency in agouti (Dasyprocta leporina). Five sexually mature agoutis underwent electroejaculation, resulting in obtaining four semen samples. After 15 days, the same animals were euthanized, and through retrograde flushing, sperm samples were obtained from the epididymis tails. In both collection methods, samples were evaluated for sperm parameters (sperm concentration, motility, vigor, membrane integrity, osmotic response, and morphology). Then, samples were diluted in ACP 109c, added with 20% egg yolk, and a final concentration of 6% glycerol. Finally, the samples were packaged in 0.25 mL straws and frozen in liquid nitrogen. After one week, samples were thawed and evaluated in the same way as fresh samples, with the addition of membrane integrity analysis using fluorescent probes (C-FDA/PI) and computerized analysis (CASA). Immediately after obtaining the sperm, samples obtained directly from the epididymis presented higher values (P ≤ 0.05) than those obtained by electroejaculation concerning the parameters of volume, sperm concentration, and total number of sperm (1,398.25 ± 206.0 x106 and 184.5 ± 78.0 x106 sperm). On the other hand, in the classical evaluation of the other sperm parameters and the computerized analysis (CASA) after thawing, such as total motility, no statistical differences were observed between sperm from both origins (ejaculate: 16.7 ± 8.2% and epididymal: 24.8 ± 12.0%, P > 0.05). This demonstrates the possibility of direct application of the cryopreservation protocol for agouti (D. leporina) sperm obtained via the epididymis or ejaculate.

BACKGROUND: Tungiasis is a disease associated with extreme poverty. We aimed to evaluate the prevalence of tungiasis in six different settlements of the Sanumás indigenous community in a remote area in the Auaris region, Yanomami territory, Brazil. METHODS: We conducted an observational study to detect clinical and epidemiological factors associated with tungiasis using a cross-sectional strategy and multivariate logistic regression. Soil analysis was performed by visual and microscopic methods. RESULTS: We examined 555 persons, 45 of whom had active tungiasis; 18 cases were classified as mild, 16 as moderate and 11 as severe. The disease was significantly more prevalent in children than in adults (odds ratio (OR) 15.77; 95% confidence interval (CI) = 5.34-67.91; p < 0.001). Soil infestation was significantly related to the occurrence of human tungiasis (OR = 12.29; 95% CI = 3.75-45.88). The sex and GPS location of the houses were not related to the occurrence of tungiasis. CONCLUSIONS: We conclude that tungiasis is an important problem in the Sanumás community, especially for children. We suggest that interruption of the off-host transmission cycle, together with regular treatment [human and animal interventions], must be prioritized to achieve control of tungiasis in indigenous populations.
RESUMO
Invasive meningococcal disease (IMD), caused by Neisseria meningitidis, is a public health problem, associated with high levels of morbidity and mortality, capable of causing outbreaks or epidemics, but preventable through vaccination. In Brazil, the main serogroups isolated are C and B. The last epidemic occurred in the '80s, in São Paulo, because of a B:4:P1.15 strain. Adult Swiss mice were immunized with outer membrane vesicles (OMV) of N. meningitidis strain C:4:P1.15, adjuvanted by the cationic lipid dioctadecyldimethylammonium bromide in bilayer fragments (DDA-BF), administered via prime-booster (intranasal/subcutaneous) scheme. The humoral response was assessed by Immunoblotting and ELISA, using homologous immunization strain and a different serogroup but equal serosubtype strain, N. meningitidis B:4:P1.15. Immunoblotting revealed the recognition of antigens associated with the molecular weight of Porin A and Opacity proteins, which are immunogenic but highly heterogeneous, and Tbp and NspA, which are more homogeneous between meningococci strains. ELISA results showed antibody production that persisted after 190 days and recognized the C:4:P1.15 and the B:4:P1.15 strains, with high avidity index. The adjuvanted group recognized antigens following the IN prime and had a higher avidity index against the heterologous strain. DDA-BF improved the humoral response, but the OMV alone induced high avidity index antibodies as well. Even though these are preliminary results, we see it as a promising approach for affordable meningococcal immunization in developing countries, at outbreak or epidemic situations. (AU)

Undergraduate students are usually subjected to a routine with constant pressure, stress, circadian misalignment, and sleep irregularity that impairs their subjective well-being. Recent evidence suggests that circadian preference is also a risk factor for impaired mental health and factors related to subjective well-being. This study aimed to identify the sociodemographic factors associated with subjective well-being and describe the mediating behavioral variables. Between September 2018 and March 2021, 615 Brazilian students enrolled in higher educational institutions completed an electronic form containing questionnaires on subjective well-being, sociodemographic, and behavioral-related factors (convenience sample). A statistical mediation model was applied to describe how these variables influence subjective well-being. We observed that Morningness (p < .001), identification with the male gender (p = .010), not working while studying (p = .048), and the practice of Pilates/yoga (p = .028) were associated with greater subjective well-being. Except for employment status, no direct effects were observed, which reinforces the need to consider a multidimensional approach. The relationship between subjective well-being and sociodemographic factors exists only in the presence of behavioral mediators, specifically perceived stress, daytime sleepiness, symptoms of depression, sleep quality, and positive and negative affects. Future work should investigate in more detail the impact of sleep, stress, and circadian preferences on this relationship.

Introduction Systematic reviews and metanalyses have shown that mindfulness-based interventions can have positive effects on health, such as reducing anxiety, depression, and chronic pain. However, their effect on sleep-related outcomes is not yet well established. Sleep can be assessed subjectively (questionnaires, sleep logs, self-reporting) and/or objectively (actigraphy, polysomnography, biological markers), and outcomes may differ depending on which type of assessment is used. Objective In this study, we present a literature overview on mindfulness and sleep, innovatively presenting and discussing studies that address sleep subjectively and objectively. Methods The search was undertaken using four databases (Pubmed Medline, Scopus, Web of Science, Psychinfo) in September 2019, and repeated in May 2021. Studies were analyzed through a two-step process: (1) reading titles and abstracts, and (2) full text analysis that met the review's eligibility criteria, with the final sample comprising 193 articles. We observed a growth in the number of studies published, particularly since 2005. However, this was mostly due to an increase in studies based on subjective research. There is a moderate to nonexistent agreement between objective and subjective sleep measures, with results of subjective measures having higher variability and uncertainty.We identified 151 articles (78%) using an exclusively subjective sleep evaluation, which can cause a misperception about mindfulness effects on sleep. Conclusion Future studies should place greater emphasis on objective measurements to accurately investigate the effects of mindfulness practices on sleep, although subjective measures also have a role to play in respect of some aspects of this relationship.
RESUMO
Abstract Objective: The aim of this study was to identify which types of skin reactions are associated with slime toys and which of their ingredients are most frequently involved in cases of poisoning. Data source: Between January and July 2021, articles were selected using PubMed, SciELO, and LILACS databases. The following descriptors were used: (dermatitis OR rash OR eczema OR inflammation) AND slime. Inclusion criteria were articles available in full, in either Portuguese, English, or Spanish, published between January 2000 and July 31, 2021, and articles reporting cases of contact dermatitis or eczema potentially or directly attributed to slime toys. Articles not meeting these criteria and duplicate texts in the databases were excluded. Data synthesis: In total, 65 publications were identified, of which 16 were included in this review. This resulted in a total of 22 children (2 males, 20 females), aged between 4 and 13 years, who were reportedly intoxicated by slime toys, most of these being linked to homemade preparations. Studies reported the occurrence of contact or allergic dermatitis on hands, fingers, nails, forearms, and cheeks. The most allergenic and/or irritant ingredients included liquid detergent and soap. Additionally, patch tests identified positive reactions to methylisothiazolinone and methylchloroisothiazolinone, the preservatives used by chemical industries on preparation of glue, soap, detergents, etc. Conclusions: Although slime toys might be important for improving motor development and parental relationships, homemade slime toy recipes include several allergenic and irritant ingredients which might be exposed to vulnerable children and cause intoxications. Therefore, homemade slime toys preparations should be used cautiously and under the supervision of adults.
Resumo Objetivo: Identificar quais tipos de reações de pele e ingredientes do brinquedo slime estão frequentemente envolvidos em relatos de intoxicação. Fontes de dados: Entre janeiro e julho de 2021, ocorreu a seleção dos artigos, utilizando-se as bases de dados: United States National Library of Medicine (PubMed), Scientific Electronic Library Online (SciELO) e Literatura Latino-Americana e do Caribe em Ciências da Saúde (LILACS). Foram utilizados os seguintes descritores: (dermatitis OR rash OR eczema OR inflammation) AND slime. Incluíram-se artigos disponíveis na íntegra, em português, inglês ou espanhol, publicados entre janeiro de 2000 e 31 julho de 2021, que relatassem casos de crianças e adolescentes que apresentaram reação cutânea após a manipulação do brinquedo slime. Foram excluídos artigos sem aderência ao tema e textos duplicados nas bases de dados. Síntese dos dados: Identificaram-se 65 publicações, sendo 16 utilizadas para a elaboração desta revisão. Isso resultou no total de 22 crianças (duas do sexo masculino, 20 do feminino), com idades entre quatro e 13 anos, que teriam sido intoxicadas por slime, a maioria dos casos ligado a preparações caseiras. Estudos relataram a ocorrência de dermatite de contato ou alérgica nas mãos, dedos, unhas, antebraços e bochechas. Os ingredientes mais alergênicos e/ou irritantes foram detergentes líquidos e sabão. Ademais, o patch test identificou reações positivas para metilisotiazolinona e metilcloroisotiazolinona, que são conservantes utilizados em produtos como cola, sabão, detergente, etc. Conclusões: Ainda que o brinquedo slime seja importante para o desenvolvimento motor e das relações parentais, receitas caseiras incluem vários ingredientes alergênicos e irritantes, que podem ser expostos a crianças vulneráveis e causar intoxicações. Sendo assim, as preparações do slime devem ser feitas com cautela e sob supervisão de adultos.

RESUMO
Cardiovascular diseases (CVD) are the deadliest noncommunicable disease worldwide. Hypertension is the most prevalent risk factor for the development of CVD. Although there is a wide range of antihypertensive drugs, there still remains a lack of blood pressure control options for hypertensive patients. Additionally, natural products remain crucial to the design of new drugs. The natural product 7-hydroxycoumarin (7-HC) exhibits pharmacological properties linked to antihypertensive mechanisms of action. This study aimed to evaluate the vascular effects of 7-HC in an experimental model of essential hypertension. The isometric tension measurements assessed the relaxant effect induced by 7-HC (0.001 µM-300 µM) in superior mesenteric arteries isolated from hypertensive rats (SHR, 200-300 g). Our results suggest that the relaxant effect induced by 7-HC rely on K+-channels (KATP, BKCa, and, to a lesser extent, Kv) activation and also on Ca2+ influx from sarcolemma and sarcoplasmic reticulum mobilization (inositol 1,4,5-triphosphate (IP3) and ryanodine receptors). Moreover, 7-HC diminishes the mesenteric artery's responsiveness to α1-adrenergic agonist challenge and improves the actions of the muscarinic agonist and NO donor. The present work demonstrated that the relaxant mechanism of 7-HC in SHR involves endothelium-independent vasorelaxant factors. Additionally, 7-HC reduced vasoconstriction of the sympathetic agonist while improving vascular endothelium-dependent and independent relaxation.

BACKGROUND: Melasma is an acquired hyperpigmentation disorder. Microneedling is an alternative treatment for melasma especially by improving penetration of pharmacological agents into the skin. OBJECTIVE: The main objective of this review was to systematize and analyze available evidence on the efficacy and safety of microneedling alone or associated with topical agents in reducing skin stains and improving melasma-related quality of life in adult patients. METHODS: Only randomized clinical trials were included. The following databases were consulted: MEDLINE, Embase, Cochrane, and the gray literature. The Cochrane risk-of-bias tool for randomized trials (RoB 2.0) was used to assess risk of bias. RESULTS: The search retrieved 719 records and seven studies were included. A total of 368 participants (96.19% women) were evaluated. Two studies were split-face. Most of the studies evaluated microneedling associated with tranexamic acid. High risk of bias was presented by most studies, especially in the safety outcome. A significant decrease was observed in the MASI, mMASI, or hemi-MASI scores, regardless of the topical agents associated. Meta-analysis was not possible due to the heterogeneity of the studies. CONCLUSION: Based on the results of this review, microneedling can, in association with topical agents or isolated, be used safely in the treatment of melasma in the clinical practice, obtaining results on reduction of stain severity and improvement of patients' quality of life.

Human papillomavirus (HPV) and human immunodeficiency virus (HIV) infections are sexually transmitted. There are several HPV genotypes and clinical manifestations. Determining which genotypes circulate worldwide and/or in specific geographic areas can help with prevention programs and vaccine distribution. This systematic review aimed to investigate the most frequent anal and cervical HPV genotypes in women co-infected with HPV/HIV. The PubMed, Scientific Electronic Library Online, and Latin American and Caribbean Literature in Health Sciences databases were used to search for articles published between January 2015 and August 2021, and the included articles followed the defined selection criteria. Based on the 51 articles included, HPV16 was the most prevalent (41%) genotype, followed by HPV52 (17%) and HPV58 (14%). Based on the comparative analyses of the HIV-negative women with HPV and the HPV/HIV co-infected groups, HPV16 was frequent in both groups; HPV58, HPV31, and HPV52 were more frequent in the co-infected group; and HPV18 was more common in HIV-negative women with HPV. HPV/HIV co-infected women most frequently presented the HPV genotypes 16, 58, and 52, whereas HIV-negative women with HPV had a higher frequency of HPV16, HPV18, and HPV52 genotypes. The results indicate the importance of genotype surveillance as a strategy to improve preventive measures against HPV infection and its complications.

Path planning techniques are of major importance for the motion of autonomous systems. In addition, the chosen path, safety, and computational burden are essential for ensuring the successful application of such strategies in the presence of obstacles. In this context, this work introduces a modified potential field method that is capable of providing obstacle avoidance, as well as eliminating local minima problems and oscillations in the influence threshold of repulsive fields. A three-dimensional (3D) vortex field is introduced for this purpose so that each robot can choose the best direction of the vortex field rotation automatically and independently according to its position with respect to each object in the workspace. A scenario that addresses swarm flight with sequential cooperation and the pursuit of moving targets in dynamic environments is proposed. Experimental results are presented and thoroughly discussed using a Crazyflie 2.0 aircraft associated with the loco positioning system for state estimation. It is effectively demonstrated that the proposed algorithm can generate feasible paths while taking into account the aforementioned problems in real-time applications.

OBJECTIVE: The present study aimed to understand patient perception of the adverse effects of contraceptives to improve health care and adherence to treatment. METHODS: An online questionnaire was available for women in Brazil to respond to assess their perception of adverse effects and their relationship with contraceptive methods. RESULTS: Of all 536 women who responded, 346 (64.6%) reported current contraceptive use. One hundred and twenty-two (122-34.8%) women reported having already stopped using contraception because of the adverse effects. As for the contraceptive method used, the most frequent was the combined oral contraceptive (212-39.6%). When we calculated the relative risk for headache, there was a relative risk of 2.1282 (1.3425-3.3739; 95% CI), suggesting that the use of pills increases the risk of headache, as well as edema, in which a relative risk of 1.4435 (1.0177-2.0474; 95% CI) was observed. For low libido, the use of oral hormonal contraceptives was also shown to be a risk factor since its relative risk was 1.8805 (1.3527-2.6142; 95% CI). As for acne, the use of hormonal contraceptives proved to be a protective factor, with a relative risk of 0.3015 (0.1789-0.5082; 95% CI). CONCLUSION: The choice of a contraceptive method must always be individualized, and the patients must be equal participants in the process knowing the expected benefits and harms of each method and hormone, when present.
OBJETIVO: Este estudo é destinado a entender a percepção de pacientes sobre os efeitos adversos dos métodos contraceptivos para aprimorar o atendimento médico e a aderência das mulheres ao tratamento. MéTODOS: Um questionário online foi disponibilizado para que mulheres no Brasil respondessem a fim de avaliar a sua percepção em relação aos efeitos adversos e a associação desses aos métodos contraceptivos. RESULTADOS: Das 536 mulheres que responderam, 346 (64,5%) alegaram uso atual de método contraceptivo. Cento e vinte e duas (12234,8%) mulheres disseram que já haviam parado o uso de métodos contraceptivos devido aos seus efeitos adversos. Quanto ao método contraceptivo em uso, o mais frequentemente utilizado foi o contraceptivo hormonal oral combinado (21239,6%). Quando calculamos o risco relativo para cefaleia, foi encontrado um risco relativo de 2,1282 (1,34253,3739; 95% intervalo de confiança [IC]), sugerindo que o uso das pílulas aumenta o risco de ocorrência desse efeito adverso, bem como de edema, cujo risco relativo foi de 1,4435 (1,01772,0474; 95% IC). Em relação à redução da libido, o uso de contraceptivo hormonal oral combinado foi também considerado um fator de risco, pois seu risco relativo foi 1,8805 (1,35272,6142; 95% IC). No que se refere à acne, o uso de contraceptivos hormonais demonstrou ser um fator de proteção, com risco relativo de 0,3015 (0,17890,5082; 95% IC). CONCLUSãO: A escolha de um método contraceptivo deve sempre ser individualizada, e as pacientes devem participar igualmente nesse processo sabendo dos benefícios e malefícios esperados de cada método e hormônio, quando presente.

Abstract Objective The present study aimed to understand patient perception of the adverse effects of contraceptives to improve health care and adherence to treatment. Methods An online questionnaire was available for women in Brazil to respond to assess their perception of adverse effects and their relationship with contraceptive methods. Results Of all 536 women who responded, 346 (64.6%) reported current contraceptive use. One hundred and twenty-two (122-34.8%) women reported having already stopped using contraception because of the adverse effects. As for the contraceptive method used, the most frequent was the combined oral contraceptive (212-39.6%). When we calculated the relative risk for headache, there was a relative risk of 2.1282 (1.3425-3.3739; 95% CI), suggesting that the use of pills increases the risk of headache, as well as edema, in which a relative risk of 1.4435 (1.0177-2.0474; 95% CI) was observed. For low libido, the use of oral hormonal contraceptives was also shown to be a risk factor since its relative risk was 1.8805 (1.3527-2.6142; 95% CI). As for acne, the use of hormonal contraceptives proved to be a protective factor, with a relative risk of 0.3015 (0.1789-0.5082; 95% CI). Conclusion The choice of a contraceptive method must always be individualized, and the patients must be equal participants in the process knowing the expected benefits and harms of each method and hormone, when present.

This study aimed to elucidate the sedative effect and physiological changes associated with the intramuscular injection of detomidine combined with morphine in horses. Six healthy crossbred horses, aged 2 to 10 years, were included. A crossover experimental design was used to compare the effects of intramuscular injection of 30 µg/kg of detomidine alone (IMD) and intramuscular administration of 30 µg/kg of detomidine and 0.1 mg/kg of morphine (IMDM). The degree of sedation, height of head above ground, were assessed at the time points before and 5, 10, 20, 30, 40, 50, 60, 75, 90, 105, and 120 minutes after drug administration, and heart rate, respiratory rate, systolic blood pressure, rectum temperature and intestinal motility were assessed at the time points before and 10, 20, 30, 40, 50, 60, 75, 90, 105, and 120 minutes after drug administration. The physiological parameters were analyzed using the Kruskal-Wallis test with Dunn's post-hoc test and analysis of variance with t-test for independent samples and the sedation scores using the Friedman test and Mann Whitney U-test. P-values <0.05 indicated a statistically significant difference. IMDM promoted a higher sedative effect as compared to IMD, but the sedation occurred inconsistently. Additionally, a reduction in intestinal motility was observed with IMDM at 60, 75, 90, and 105 minutes after administration. IMDM promoted more variable sedation and prolonged reduction in the intestinal motility in the horses as compared to IMD.
Este trabalho teve por objetivo elucidar o efeito sedativo e alterações fisiológicas em cavalos associados à injeção intramuscular de detomidina combinada com morfina. Seis cavalos saudáveis e sem raça definida, com idade de dois a 10 anos, foram incluídos. Delineamento experimental cruzado foi usado para comparar os efeitos da administração intramuscular de 30 µg/kg detomidina isolada (IMD) e da administração intramuscular de 30 µg/kg de detomidina associada à morfina a 0,1 mg/kg (IMDM). Avaliou-se o grau de sedação, a altura da cabeça acima do solo nos momentos antes (M0) e 5, 10, 20, 30, 40, 50, 60, 75, 90, 105 e 120 minutos após administração dos fármacos, e frequência cardíaca, frequência respiratória, pressão arterial sistólica, temperatura retal e motilidade intestinal foram avaliados nos momentos antes (M0) e 10, 20, 30, 40, 50, 60, 75, 90, 105 e 120 minutos após administração dos fármacos. Para análise estatística foram utilizados: teste de Kruskal-Wallis, com pós-teste de Dunn, e ANOVA associada ao teste t para amostras independentes para os parâmetros fisiológicos; e teste de Friedman e teste de Mann Whitney para os escores de sedação. Valores de P < 0.05 indicaram diferença significativa. A administração de detomidina associada à morfina pela via intramuscular (IM) promoveu maior efeito sedativo, quando comparada à administração isolada de detomidina IM. Contudo, a sedação ocorreu de forma inconsistente. Também foi observado, no IMDM, redução da motilidade intestinal aos 60, 75, 90 e 105 minutos de avaliação. A associação de morfina e detomidina pela via intramuscular promove sedação de forma variável em cavalos, e resulta em redução da motilidade intestinal, mais prolongada quando comparada a administração isolada de detomidina intramuscular.
