A modified tunnel technique to treat multiple gingival recessions: Case Series

Abstract This case series reports a modified tunnel technique with connective tissue graft for the root coverage of multiple Miller Class I, II, and III gingival recessions. The modified approach presents an innovative suture technique to improve the stability and position of the graft. Ten patients with multiple gingival recessions (n=85 teeth) received surgical root coverage treatment. The gingival recession height and width were measured and presented as median, minimum, and maximum values. The percentage of the root coverage after at least 12 months expressed the treatment effectiveness. The Shapiro-Wilk test evaluated the normality; pared Wilcoxon test determined the exact P-value for the differences in the height of the gingival recession before and after surgical treatment (α = 0.05). An average of 97.9% (± 5.6%, p < 0.0001) root coverage after treatment occurred, and 73 out of 85 recessions presented complete root coverage after 12 months. Treatment of Miller class I and II gingival recessions resulted in root coverage higher than 99 and class III higher than 95% (p < 0.0001). The presented case series report the efficacy of a modified surgical technique promoting more than 95% of root coverage after 12 months in multiple Miller Class I, II, and III gingival recessions. Well-designed blind randomized controlled trials are needed to validate the proposed technique.

Resumo Esta série de casos relata uma técnica de túnel modificada com enxerto de tecido conjuntivo para o recobrimento radicular de múltiplas recessões gengivais Classe I, II e III de Miller. A abordagem modificada apresenta uma técnica de sutura inovadora para melhorar a estabilidade e a posição do enxerto. Dez pacientes com múltiplas recessões gengivais (n=85 dentes) receberam tratamento cirúrgico de recobrimento radicular. A altura e a largura da recessão gengival foram mensuradas e apresentadas como valores medianos, mínimos e máximos. A eficácia do tratamento foi expressa como uma porcentagem da cobertura radicular após pelo menos 12 meses. O teste de Shapiro-Wilk avaliou a normalidade; o teste de Wilcoxon pared determinou o valor P exato para as diferenças entre a altura da recessão gengival antes e após o tratamento cirúrgico (α = 0,05). Uma média de 97,9% (± 5,6%, p < 0,0001) de cobertura radicular após o tratamento ocorreu, e 73 das 85 recessões apresentaram cobertura radicular completa após 12 meses. O tratamento das recessões gengivais classe I e II de Miller resultou em recobrimento radicular superior a 99 e classe III superior a 95% (p < 0,0001). A série de casos apresentada relata a eficácia de uma técnica cirúrgica modificada promovendo mais de 95% de cobertura radicular após 12 meses em múltiplas recessões gengivais Classe I, II e III de Miller. Ensaios controlados randomizados cegos bem desenhados são necessários para validar a técnica proposta.

Cognitive assessment of Brazilian patients with multiple sclerosis: weighing the impact of disability and depressive symptoms / Avaliação cognitiva de pacientes brasileiros com esclerose múltipla: análise do impacto da incapacidade e dos sintomas depressivos

ABSTRACT Multiple sclerosis (MS) is the most common demyelinating disease of the central nervous system. Cognition is not routinely assessed in patients with MS though they frequently have cognitive complaints or dysfunction. Objective: The aim of this study was to compare the cognitive status of patients with MS with age, sex, and schooling matched controls and to evaluate the potential influence of clinical parameters on cognition. Methods: A total of 35 patients with MS (mean±SD age 37.9 years±11.44, M/F: 12/23) and 33 healthy controls (mean±SD age 38.8 years±12.6, M/F: 12/21) were enrolled in this study. All subjects underwent a structured clinical assessment and the cognitive tools are as follows: Paced Auditory Serial Addition Test (PASAT), Symbol Digit Modalities Test (SDMT), Rey Auditory Verbal Learning Test (RAVLT), Digit Span, and Verbal Fluency Tests (letters F, A, and S and animal category). Psychopathology was assessed with the Mini International Neuropsychiatric Interview and the Beck Depression Inventory (BDI). The Expanded Disability Status Scale (EDSS) was used for patients. Results: Patients performed worse than controls in almost all tests, with approximately 70% of patients presenting cognitive impairment. The most affected cognitive domain was episodic memory (45.7%), followed by verbal fluency (42.8%) and information processing speed (22.8%). SDMT was inversely correlated with disease severity, as assessed by the EDSS. Depression did not influence cognitive performance in this cohort. Conclusions: Cognitive dysfunction is common among patients with MS. While motor impairment was associated with information processing speed, depression did not influence cognitive performance.

RESUMO A esclerose múltipla (EM) é a doença desmielinizante mais comum do sistema nervoso central. A cognição não é rotineiramente avaliada nos pacientes apesar da ocorrência frequente de queixas ou disfunção cognitivas. Objetivo: Comparar o perfil de pacientes com EM com controles pareados por idade, sexo e escolaridade e investigar a potencial influência de parâmetros clínicos na cognição. Métodos: Trinta e cinco pacientes com EM (idade média±desvio padrão [DP] 37,9 anos±11,44, H/M: 12/23) e 33 controles saudáveis (idade média±DP 38,8 anos±12,6, H/M: 12/21) foram incluídos neste estudo. Todos os participantes passaram por avaliação clínica estruturada e por testagem cognitiva com os seguintes instrumentos: Paced Auditory Serial Addition Test (PASAT), Symbol Digit Modalities Test (SDMT), Rey Auditory Verbal Learning Test (RAVLT), Digit Span e testes de fluências verbais (letras F, A e S e categoria-animais). A psicopatologia foi investigada com a Mini International Neuropsychiatric Interview e com o Beck Depression Inventory (BDI). A Expanded Disability Status Scale (EDSS) foi aplicada nos pacientes. Resultados: Pacientes tiveram desempenho pior que os controles na maioria dos testes — 70% deles tiveram déficit cognitivo. A função cognitiva mais frequentemente afetada foi memória episódica (45,7%), seguida por fluência verbal (42,8%) e velocidade de processamento (22,8%). A pontuação no SDMT correlacionou-se inversamente com a gravidade da doença, medida pela EDSS. A depressão não influenciou o desempenho cognitivo nesta série de pacientes. Conclusões: Declínio cognitivo é comum em pacientes com EM. Enquanto o déficit motor se associou com a velocidade de processamento, a depressão não influenciou o desempenho cognitivo.

Efecto sedativo de Dexmedetomidina intranasal versus sublingual más Remifentanil-Propofol mediante bombas de infusión

Objetivos: evaluar el efecto de dexmedetomidina sublingual frente a dexmedetomidina vía nasal más remifentanilo -propofol con bomba de infusión en procedimientos ginecológicos. Métodos: ensayo clínico no controlado, doble ciego, prospectivo. 68 pacientes con criterios de inclusión dividas en 3 grupos, grupo A [dexmedetomidina sublingual a 0.75 ug/kg], grupo B [dexmedetomidina vía nasal a 0,9 gg/kg] y grupo C [control] más adición de remifentanil y propofol por bombas de infusión. Análisis estadístico de variables cualitativas con chi cuadrado, variables cuantitativas de distribución libre se usó Kruskal-Wallis y distribución normal Anova. Nivel de confianza del 95 % y margen de error del 9 %. Resultados: edad con un rango de 30 a 32 años, la dosis de inicio y sostén tanto del remifentanilo y propofol se disminuyó hasta la mitad comparada con el grupo control, a predominio en el grupo A. Con poca variabilidad en los parámetros hemodinámicos sin repercusión clínica. Efectos adversos más frecuentes como depresión respiratoria en el grupo control, no se observó analgesia con el uso de dexmedetomidina. Y con menor tiempo de estancia en salas de recuperación en pacientes que se administró dexmedetomidina vía nasal. Conclusiones: la administración sublingual es superior con la nasal debido al menor requerimiento de propofol, menos cambios en la presión sanguínea media, sin efectos adversos que se puedan manejar, con mayor facilidad en su administración. Aunque la administración nasal produce un despertar más rápido y mejor control de la frecuencia cardiaca.

Objectives: to evaluate the effect of sublingual dexmedetomidine versus nasal dexmedetomidine plus remifentanil-propofol infusion pump in gynecological procedures. Methods: Uncontrolled, double-blind, prospective clinical trial. 68 patients with inclusion criteria were divided into 3 groups, group A [sublingual dexmedetomidine at 0.75 ug/kg], group B [nasal dexmedetomidine at 0.9 ug/kg] and group C [control] plus the addition of remifentanil and propofol by infusion pumps. Statistical analysis of qualitative variables with chi- square, quantitative variables with free distribution used Kruskal-Wallis and normal distribution Anova. Confidence level of 95% and margin of error of 9%. Results: age with a range of 30 to 32 years, the starting and maintenance dose of both remifentanil and propofol was halved compared to the control group, mainly in group A. With little variability in hemodynamic parameters without clinical repercussion. The most frequent adverse effects were respiratory depression in the control group, no analgesia was observed with the use of dexmedetomidine. And with a shorter stay in recovery rooms in patients who received nasal dexmedetomidine. Conclusions: sublingual administration is superior to nasal due to the lower requirement of propofol, less changes in mean blood pressure, with no adverse effects that can be managed, and with greater ease of administration. Although nasal administration produces a faster awakening and better control of heart rate.

Antimicrobial activity and partial chemical structure of acylpolyamines isolated from the venom of the spider Acanthoscurria natalensis

Abstract Background: Acylpolyamines are one of the main non-peptide compounds present in spider venom and represent a promising alternative in the search for new molecules with antimicrobial action. Methods: The venom of Acanthoscurria natalensis spider was fractionated by reverse-phase liquid chromatography (RP-HPLC) and the antimicrobial activity of the fractions was tested using a liquid growth inhibition assay. The main antimicrobial fraction containing acylpolyamines (ApAn) was submitted to two additional chromatographic steps and analyzed by MALDI-TOF. Fractions of interest were accumulated for ultraviolet (UV) spectroscopy and ESI-MS/MS analysis and for minimum inhibitory concentration (MIC) and hemolytic activity determination. Results: Five acylpolyamines were isolated from the venom with molecular masses between 614 Da and 756 Da, being named ApAn728, ApAn614a, ApAn614b, ApAn742 and ApAn756. The analysis of UV absorption profile of each ApAn and the fragmentation pattern obtained by ESI-MS/MS suggested the presence of a tyrosyl unit as chromophore and a terminal polyamine chain consistent with structural units PA43 or PA53. ApAn presented MIC between 128 µM and 256 µM against Escherichia coli and Staphylococcus aureus, without causing hemolysis against mouse erythrocytes. Conclusion: The antimicrobial and non-hemolytic properties of the analyzed ApAn may be relevant for their application as possible therapeutic agents and the identification of an unconventional chromophore for spider acylpolyamines suggests an even greater chemical diversity.

COVID-19 Vaccines: Bioethical Consideration / Vacunas contra la covid-19: consideración bioética / Vacinas contra a covid-19: consideração bioética

Abstract The COVID-19 pandemic produced immeasurable impacts on the economy, education, and socialization, besides the loss of mi llions of lives. Thus, there has been an accelerated development of an unprecedented number of COVID-19 vaccine candidates to control the pandemic. The World Health Organization's emergency use authorization of COVID-19 vaccines still in clinical trial allowed immunizing the population. This paper presents a perspective of the bioethical precepts of autonomy, non-maleficence, beneficence, and justice in the emergency use of COVID-19 vaccines. Furthermore, it emphasizes the importance of surveillance at all stages of vaccine development to detect adverse effects and ensure compliance with bioethical precepts.

Resumen La pandemia de la covid-19 ha tenido impactos inconmensurables en la economía, la educación y la socialización, además de la pérdida de millones de vidas. Por lo tanto, se ha acelerado el desarrollo de un número sin precedentes de candidatos a vacunas contra la covid-19 para controlar la pandemia. A su vez, la autorización para su uso de emergencia por parte de la Organización Mundial de la Salud permitió el inicio de la inmunización de la población a través de vacunas que aún se encuentran en ensayos clínicos. Aquí presentamos una perspectiva de los preceptos bioéticos de autonomía, no maleficencia, beneficencia y justicia en el contexto del uso de emergencia de vacunas contra la covid-19. Además, se enfatiza la importancia de la vigilancia en todas las etapas del desarrollo de la vacuna con el fin de detectar efectos adversos y asegurar el cumplimiento de los preceptos bioéticos.

Resumo A pandemia ocasionada pela covid-19, além da perda de milhões de vidas, vem trazendo consequências incomensuráveis para a economia, a educação e a socialização.

Por sua vez, a autorização para seu uso emergencial por parte da Organização Mundial da Saúde permitiu o início da imunização da população por meio de vacinas que ainda se encontram em ensaios clínicos. Aqui, apresentamos uma perspectiva dos princípios bioéticos de autonomia, não maleficencia, beneficência e justiça no contexto do uso emergencial de vacinas contra covid-19. Além disso, é enfatizada a importância da vigilância em todas as etapas do desenvolvimento da vacinação a fim de detectar efeitos adversos e assegurar o cumprimento dos princípios bioéticos.

Conhecimento de adolescentes e jovens sobre questões relacionadas ao sexo, em uma escola pública de Monte Alegre do Piauí-PI / Knowledge of adolescents and young people on issues related to sex, in a public school in Monte Alegre do Piauí-PI

O presente estudo objetivou avaliar o conhecimento de adolescentes e jovens sobre questões relacionadas ao sexo, na cidade de Monte Alegre do Piauí (PI). Para isso, utilizou-se o método descritivo quantitativo por meio de questionário semiestruturado aplicado a 81 estudantes, com idade entre 16 a 23 anos, da escola Ginásio Estadual Senador Chagas Rodrigues. A coleta de dados evidenciou que 97,5% (n=79) dos participantes já haviam praticado sexo, tendo iniciado com idade média de 15,5 anos. O preservativo foi o método contraceptivo mais conhecido, no entanto, observou-se que os adolescentes e jovens não se preveniram em todas as relações sexuais, mesmo cientes das consequências da não prevenção. Percebeu-se fragilidade dialógica entre os indivíduos, família e escola; a conversação sobre o assunto no âmbito familiar e escolar ainda era receosa e pouco atrativa. Como conclusão deste estudo, sugere-se como necessário a implementação eficaz de políticas públicas que envolvam de forma educativa a escola, os jovens, seus familiares e amigos.

This present study aimed to assess the knowledge of adolescents and young people on issues related to sex, in the city of Monte Alegre do Piauí (PI). For this, the quantitative descriptive method was used through a semi-structured questionnaire applied to 81 students, aged between 16 and 23 years old, from the school Ginásio Estadual Senador Chagas Rodrigues. The data collection showed that 97.5% (n = 79) of the participants had already had sex, having started with an average age of 15,5 years. The condom was the most known contraceptive method; however, it was observed that adolescents and young people did not prevent themselves in all sexual intercourse, even though they were aware of the consequences of non-prevention. Dialogical fragility was noticed among individuals, family and school; the conversation on the subject in the family and school environment was still fearful and unattractive. As a conclusion of this study, it is suggested as necessary the effective implementation of public policies that involve the school, young people, their families and friends in an educational way.

Manejo anestésico en paciente obstétrica con taponamiento cardíaco / Anesthetic management in obstetric patient with cardiac tamponade

El taponamiento cardiaco es la acumulación de líquido dentro del saco pericárdico, lo que conlleva a un aumento de la presión intrapericardica, permitiendo el deterioro de la capacidad del corazón para llenarse y actuar como bomba. Entre sus causas tenemos a la tuberculosis, las colagenopatías, y el cáncer. En el embarazo se pueden enmascarar los signos y síntomas del taponamiento cardiaco por los cambios fisiológicos propios del embarazo. El Gold estándar para su detección es la ecocardiografía. El tratamiento del taponamiento cardiaco es la pericardiocentesis o el drenaje quirúrgico. Se presenta el caso de una paciente de 26 años con: embarazo de 32,6 semanas, trabajo de parto pretérmino, taponamiento cardiaco y post pericardiocentesis de 2 horas, para culminación de embarazo. El manejo anestésico es complejo tanto para la madre y el recién nacido, basándose en mantener estabilidad hemodinámica y posterior traslado a unidad de terapia intensiva.

Cardiac tamponade is the accumulation of fluid within the pericardial sac, which leads to an increase in intrapericardial pressure, allowing the deterioration of the heart's ability to fill and act as a pump. Among its causes are tuberculosis, collagen disease, and cancer. In pregnancy, the signs and symptoms of cardiac tamponade can be masked by the physiological changes of pregnancy. The gold standard of detection is echocardiography. Treatment of cardiac tamponade is pericardiocentesis or surgical. The case of a 26-year-old patient is presented with: a 32.6 for week pregnancy in preterm labor, cardiac tamponade and 2-hour post-pericardiocentesis, for culminate of pregnancy. Anesthetic management is complex for both the mother and the newborn, basing on maintaining hemodynamic stability and subsequent transfer to the intensive care unit.

Perfil epidemiológico e conhecimento de gestantes sobre aleitamento materno em um município do nordeste brasileiro / Epidemiological profile and knowledge of pregnant women regarding breastfeeding in a city in northeastern Brazil

O aleitamento materno exclusivo propicia saúde ao recém-nascido e à mulher, fortalece o vínculo mãe e filho e leva à redução na mortalidade infantil. Objetivo: Identificar o perfil e os conhecimentos sobre aleitamento materno de gestantes atendidas em Unidades Básicas de Saúde, durante o pré-natal, no município de Gilbués, Piauí, Brasil. Material e Métodos: Trata-se de um estudo descritivo e abordagem quantitativa, com coleta de dados por meio de um formulário sobre as características sociodemográficas e conhecimentos em relação ao aleitamento materno. O estudo foi realizado com 40 gestantes nas Unidades Básicas de Saúde dos bairros São José e Santo Antônio. Resultados: Das gestantes, 75% estavam na segunda gestação ou mais e 47,5% no segundo trimestre gestacional. A maioria apresentou idade entre 18 e 30 anos, era solteira, possuía o ensino fundamental, não exercia atividade profissional e possuía renda familiar de até um salário mínimo. Quanto aos conhecimentos sobre aleitamento materno, houve orientação no pré-natal, porém, com pouca incorporação acerca dos benefícios que essa prática pode proporcionar à mãe. Apontaram-se, ainda, dúvidas e/ou inseguranças das gestantes sobre a quantidade de leite produzido e sua capacidade de nutrição, surgimento de fissuras na mama e transmissão de doenças por meio da amamentação. Conclusão: As atividades de educação em saúde no pré-natal são fundamentais para a saúde da criança e da mulher, promovendo estratégias de promoção, apoio e incentivo ao aleitamento materno.

Exclusive breastfeeding provides health to both the newborn and the mother, strengthening the bond between mother and child and leading to a reduction in infant mortality. Objective: Identify the profile and knowledge about breastfeeding of pregnant women attended at the Basic Health Units during prenatal care in the city of Gilbués, Piauí, Brazil. Methodology: This is a descriptive study, with a quantitative approach collected through a form on sociodemographic characteristics and knowledge regarding breastfeeding. The study was performed considering 40 pregnant women seen at the UBSs in the São José and Santo Antônio neighborhood. Results: Among the patients, 75% were in their second pregnancy or more, and 47.5% in the second gestational trimester. Most of them were aged between 18 and 30 years old, single, had only elementary education, did not work, and had family income up to a minimum wage. Regarding the knowledge about breastfeeding, they received guidance in the prenatal care, but with little emphasis on the benefits that exclusive breastfeeding can also provide to the mother. The doubts and/or insecurities of pregnant women were related to the amount of milk produced and its nutritional capacity, the appearance of cracks on the breast, and the transmission of diseases through breastfeeding. Conclusions: Prenatal health education activities are essential for the health of the child and the pregnant woman by providing strategies to promote, support, and encourage breastfeeding.

I See Golden Mussel! They are Everywhere! Environmental DNA Supports Widespread Dissemination of Limnoperna fortunei in Hydrographic Basins in the Paraná State, Brazil

Abstract The golden mussel is an aquatic invasive species that was introduced in South America in the '90s, including Brazil, and was firstly registered in 2001 in the Paraná state. This bivalve causes macrofouling issues because adhere in substrates and form dense aggregations, affecting especially hydroelectric power plants, and water treatment facilities, apart from the native biodiversity. The present research aimed to diagnose the distribution of Limnoperna fortunei in the Paraná state using environmental DNA (eDNA) from 174 sites from 12 basins, and scientific and technical previous records. L. fortunei eDNA was found in 90 sites from 11 hydrographic basins sampled. Most of the positive samples were detected in Iguaçu (42), Tibagi (15), and Ivaí (10) rivers basins. We also registered the first occurrence for five basins: Cinzas, Itararé, Ivaí, Pirapó e Ribeira rivers. Together, our and previous data recorded L. fortunei in 118 sites, between adult, larvae, and eDNA detection. Moreover, the results evidenced that eDNA is a low coast and reliable tool, and it may be very recommended for L. fortunei early detection and diagnosis. The present research was the greatest and most widespread survey for golden mussel prospection in a state in Brazil, supported a worrying scenario for Parana, with the urgent need for intense and continuous monitoring and prevention actions for controlling and mitigation of the L. fortunei impacts.

INTRODUCTION: we do not have experience on the use of intranasal dexmedetomidine for gynecological procedures in the environment. OBJECTIVES: to demonstrate the effects of intranasal use of dexmedetomidine in sedation for obstetric gynecological procedures. METHODS: a prospective, longitudinal, single-blind, uncontrolled clinical trial was conducted; Taking 24 patients from a universe of 80 patients, 0.9 µg/kg of intranasal dexmedetomidine was administered prior to performing the procedure. It was processed in IBM-SPPS v.25®. Calculation of mean and SD in quantitative and p value <0.05 significant. RESULTS: average age of 32 years old; basal heart rate 70 beats / min, being significant after induction and at the end of the procedure; the mean arterial pressure remained between 82 to 73 mmHg, not significant; Visual Numeric Scale was found from 0 in 18 patients; during induction and maintenance with Target Control Infusion it was found between 2 ng / ml of remifentanil and 2 mcg / ml of propofol. There were no complications in 18 patients. CONCLUSIONS: it provides hemodynamic stability at the dose used without adverse effects after administration of dexmedetomidine and produces a reduction in the doses of induction and maintenance drugs(AU)

Arritmia cardiaca posterior a anestesia espinal en cesárea / Cardiac arrhythmia after to spinal anesthesia in cesarean

La arritmia y taquicardia son muy comunes en las embarazadas, aunque el bloqueo espinal pueda ser una técnica anestésica segura, la taquicardia grave, la parada cardiaca y otras arritmias son relatadas durante las prácticas de raquianestesia. La bupivacaina y levobupivacaina pueden aumentar el intervalo PR y la duración del QRS y prolongar la conducción cardiaca. La dexmedetomidina tiene propiedades simpaticolíticas, sedativas, estabilidad respiratoria sin depresión ventilatoria, amnésicas y analgésicas, los efectos adversos de la dexmedetomidina son la hipertensión inicial, hipotensión, naúseas, bradicardia, fibrilación atrial, edema pulmonar, oliguria y sed. Paciente de 33 años de edad con embarazo de 39,2 sem. Sin antecedentes patológicos. Recibe anestesia espinal y a los 10 min bradicardica de 39 corregida con atropina y posterior con arritmia sinusal. En conclusión, la presencia de arritmias cardiacas puede deberse a varios factores, es trascendental la vigilancia y monitoreo continuo del electrocardiograma para reconocer y corregir de manera oportuna.

Arrhythmia and tachycardia are very common in pregnant women, although spinal block may be a safe anesthetic technique, severe tachycardia, cardiac arrest and other arrhythmias are reported during spinal anesthesia practices. Bupivacaine and levobupivacaine can increase the PR interval and the duration of QRS and prolong cardiac conduction. Dexmedetomidine with sympatholytic, sedative, respiratory stability without ventilatory depression, amnesic and analgesic properties, the adverse effects of dexmedetomidine are initial hypertension, hypotension, nausea, bradycardia, atrial fibrillation, pulmonary edema, oliguria and thirst. 33-year-old patient with a pregnancy of 39.2 weeks. No pathological history she received spinal anesthesia and at 10 min bradycardia of 39 corrected with atropine and later with sinus arrhythmia. In conclusion, the presence of cardiac arrhythmias can be due to several factors, the continuous monitoring and monitoring of the electrocardiogram to recognize and correct in a timely manner is transcendental.

Inclusion of crude corn oil with high acidity in the feed of laying hens: analysis of egs production and quality / Inclusão de óleo de milho bruto com alta acidez na alimentação de poedeiras: análise da produção e qualidade de ovos

The objective of this study was to evaluate egg production and quality after including crude corn oil with high acidity (CCOHA) in the feed of laying hens. The design was completely randomized to three treatments and six replicates each. The sample included 90 hens of the Lohmann LSL lineage, housed in cages; each cage contained five animals and constituted an experimental unit. The evaluated feeds were corn-based feed with degummed soybean oil (CSO), corn-based feed with CCOHA (CC) and sorghum-based feed with CCOHA (SC). At the end of the 28-day cycle, the following productivity parameters were evaluated: egg weight at laying (EWL), laying percentage (LP), feed conversion per dozen eggs (FCDZ) and feed conversion per egg mass (FCEM). The evaluated internal and external quality parameters of the eggs were yolk percentage (YP), yolk index (YI), and yolk pH (YpH); albumen percentage (AP), albumen index (AI), and albumen pH (ApH); percentage shell (PS) and shell surface area (SSA); Haugh unit (HU) and egg yolk color (EYC). There were no significant differences in EW, LP, FCDZ, and FCEM between the experimental feeds. Moreover, the use of crude corn oil with high acidity in laying hens rations did not influence the parameters of YP, YI, YpH, AP, AI, ApH, PS, SSA, HU, and EYC.

Objetivou-se avaliar a inclusão do óleo bruto de milho com alta acidez (OBMAA) em rações de galinhas poedeiras sobre a produção de ovos e sua qualidade interna e externa. O delineamento foi inteiramente casualizado com três tratamentos e seis repetições cada, com 90 galinhas da linhagem Lohmann LSL®, alojadas em número de cinco aves por gaiola, constituindo cada gaiola uma unidade experimental. Os tratamentos foram: rações base milho com óleo degomado de soja (MOS), milho com OBMAA (MOM) e sorgo com OBMAA (SOM). Ao final do ciclo de 28 dias determinou-se os parâmetros de produtividade: peso dos ovos na postura (POP), porcentagem de postura (POS) e conversões alimentares por dúzia (CAD) e por massa de ovos (CAM). Em seguida foram realizadas as análises de qualidade interna e externa dos ovos: percentagem, índice e pH da gema (GE%, IGE, pHGE), percentagem, índice e pH do albúmen (AL%, IAL, pHAL), percentagem e superfície de área de casca (CAS%, SACAS), unidade Haugh (UH) e colorimetria da gema. Não houve diferença para POS e POP, CAD e CAM das rações experimentais. A utilização do óleo bruto de milho com alta acidez nas rações de galinhas poedeiras não influenciou nos parâmetros de GE%, IGE, pHGE, AL%, IAL, pHAL, CAS%, SACAS, UH e colorimetria da gema
