Morphophysiological changes of Acca sellowiana (Myrtaceae: Myrtoideae) saplings under shade gradient / Alterações morfofisiológicas em mudas de Acca sellowiana (Myrtaceae: Myrtoideae) sob gradiente de sombreamento

Abstract Understanding morphological and physiological changes under different light conditions in native fruit species in juveniles' stage is important, as it indicate the appropriate environment to achieve vigorous saplings. We aimed to verify growth and morphophysiological changes under shade gradient in feijoa (Acca sellowiana (O. Berg) Burret) to achieve good quality saplings adequate to improve cultivation in orchards. The saplings were grown for twenty-one-month under four shading treatments (0%, 30%, 50%, and 80%). Growth, photosynthetic pigments, gas exchanges, chlorophyll fluorescence, and leaf anatomy parameters were evaluated. Saplings under full sun and 30% shade had higher height and diameter growth and dry mass accumulation due to higher photosynthesis rate. As main acclimatization mechanisms in feijoa saplings under 80% shade were developed larger leaf area, reduced leaf blade thickness, and enhanced quantum yield of photosystem II. Even so, the net CO2 assimilation and the electron transport rate was lower and, consequently, there was a restriction on the growth and dry mass in saplings under deep shade. Therefore, to obtain higher quality feijoa saplings, we recommend that it be carried out in full sun or up to 30% shade, to maximize the sapling vigor in nurseries and, later, this light environment can also be used in orchards for favor growth and fruit production.

Resumo A verificação de mudanças morfológicas e fisiológicas sob diferentes condições luminosas em espécies frutíferas nativas em estágio juvenil é importante, uma vez que indicam o ambiente adequado para a formação de mudas com alto vigor. Objetivou-se verificar o crescimento e as alterações morfofisiológicas sob gradiente de sombreamento em mudas de feijoa (Acca sellowiana (O. Berg) Burret) para obter mudas de boa qualidade, adequadas para fomentar os plantios da espécie em pomares. As mudas foram cultivadas por vinte e um meses sob quatro tratamentos de sombreamento (0%, 30%, 50% e 80%). Foram avaliados parâmetros de crescimento, pigmentos fotossintéticos, trocas gasosas, fluorescência da clorofila e anatomia foliar. Mudas a pleno sol e 30% de sombra apresentaram maior crescimento em altura, diâmetro e acúmulo de massa seca, devido à maior taxa de fotossíntese. Como principais mecanismos de aclimatação sob 80% de sombra, as mudas desenvolveram maior área foliar, redução da espessura do limbo foliar e aumento do rendimento quântico do fotossistema II. Mesmo assim, a assimilação líquida de CO2 e a taxa de transporte de elétrons foram menores e, consequentemente, houve restrição ao crescimento e acúmulo de massa seca das mudas no maior nível de sombreamento. Portanto, para a obtenção de mudas de feijoa de maior qualidade, recomendamos que seja realizada a pleno sol ou até 30% de sombra, para maximizar o vigor das mudas em viveiros e, posteriormente, este ambiente de luz também pode ser utilizado em pomares para favorecer o crescimento e a produção de frutos.

Twenty-four hours stay after colorectal surgery: a systematic review

Introduction: The introduction of Enhanced Recovery After Surgery led to increasing twenty-four hours discharge pathways, for example in laparoscopic cholecystectomy and bariatric surgery. However, implementation in colorectal surgery still must set off. This systematic review assesses safety and feasibility of twenty-four hours discharge in colorectal surgery in terms of readmission and complications in current literature. Secondary outcome was identification of factors associated with success of twenty-four hours discharge. Methods: Pubmed and EMBASE databases were searched to identify studies investigating twenty-four hours discharge in colorectal surgery, without restriction of study type. Search strategy included keywords relating to ambulatory management and colorectal surgery. Studies were scored according to MINORS score. Results: Thirteen studies were included in this systematic review, consisting of six prospective and seven retrospective studies. Number of participants of the included prospective studies ranged from 5 to 157. Median success of discharge was 96% in the twenty-four hours discharge group. All prospective studies showed similar readmission and complication rates between twenty-four hours discharge and conventional postoperative management. Factors associated with success of twenty-four hours discharge were low ASA classification, younger age, minimally invasive approach, and relatively shorter operation time. Conclusions: Twenty-four hours discharge in colorectal surgery seems feasible and safe, based on retro- and prospective studies. Careful selection of patients and establishment of a clear and adequate protocol are key items to assure safety and feasibility. Results should be interpreted with caution, due to heterogeneity. To confirm results, an adequately powered prospective randomized study is needed. (AU)

Relationship of Serum Lipid Profile and Blood Pressure with Body Mass Index (BMI)

Background: Obesity and overweight is a disorder of unusually increased body fat generally resulting from increased energy intake relative to energy expenditure and is a primary sustenance-related disorder globally. The extensive increase in its prevalence in current years and its association with reduced life expectancy has made obesity one of the most vital public health problems. The purpose of the study was to determine the relationship between serum lipid profile and blood pressure with body mass index (BMI). Material & Methods: A cross-sectional study was carried out in the Department of Physiology and Biochemistry, Rangpur Medical College, Rangpur from January 2013 to December 2013. A purposive sampling technique was followed. A total number of 90 people from 18 to 45 years old were included in the study, categorized into three groups, such as Group-A:(Control 30): Healthy subject of normal weight, Group-B:(Experimental 30): Healthy subject of overweight & Group-C(Experimental-30): Healthy subjects of obese. Verbal consent was taken before recruiting the study population. Completed data forms were reviewed, edited, and processed for computer data entry. The data analysis was performed using the “t” test, “r” test & Statistical Package for the Social Sciences (SPSS) Version 25.0. Results: In group A, the mean BMI of patients was 18.5-22.9, in group B mean BMI of patients was 23.0-24.9, and in group C, the mean BMI of people was 25.0 or greater. The mean ± SD serum LDL-C levels were 107.77 ± 26.720 mg/dl in group A and 134.70 ± 41.787 mg/dl in group B. There was a significant difference (p<0.001) between the two groups. The mean ± SD pulse pressure levels were 38 ± 6.644 mmHg in group A and 41.67 ± 11.167 mmHg in group B. There was no significant difference (p>0.05) between the two groups. Serum total cholesterol levels were positively correlated in groups A & B but the relationship of serum total cholesterol levels was statistically significant in groups A and B. Blood pressure levels were positively correlated in groups A &C but the relationship was statistically non-significant. Conclusion: In this current content, it is difficult to define the specific mechanism involved for significantly higher serum total cholesterol, serum triglyceride, and serum LDL-C levels and non-significantly lesser serum HDL-C levels in overweight & obese people and also non-significantly higher blood pressure in overweight people but significantly higher blood pressure in obese subjects.

Impact de la pandémie de COVID-19 sur le suivi des maladies systémiques: enquête transversale multicentrique à Dakar / How the outbreak of COVID-19 did affected the follow-up of patients known for an autoimmune or autoinflammatory systemic diseases in Dakar

Introduction : La pandémie de covid-19 a eu un impact sur les systèmes de santé, entravant la prise en charge optimale des maladies chroniques. L'objectif de notre étude était d'évaluer son impact sur le suivi des pathologies systémiques. Patients - Méthodes : Nous avons mené une enquête transversale multicentrique dans les services de Médecine Interne, de Rhumatologie et de Néphrologie à Dakar. Les patients étaient inclus en accord avec les critères de consensus internationaux. L'enquête a porté sur les dossiers concernant 13 questions et a été complétée par un entretien téléphonique avec 38 questions potentielles. Les réponses étaient collectées grâce à une application Web puis exportées et analysées avec le logiciel SPSS 26.0. Résultats : Du 1er Août au 31 Octobre 2021, 131 patients ont été inclus avec un âge moyen de 41,5 ans (+/-12,4) et un sex-ratio de 0,08. Les pathologies inflammatoires étaient dominées par la polyarthrite rhumatoïde (47,3%) et le lupus systémique (22,9%). Les patients ont rapporté avoir raté un ou plusieurs rendez-vous de suivi dans 45% des cas. Les motifs étaient dominés par une difficulté d'obtenir un rendez-vous de suivi (18,6%) et la peur de fréquenter les hôpitaux (16,9%). Une rupture médicamenteuse a été notée dans 33,6% des cas et concernait notamment l'hydroxychloroquine (40,9%) ou le méthotrexate (47,7%) avec comme raison principale les ruptures de stock en pharmacie et les difficultés économiques. Une poussée de la maladie systémique a été rapportée dans 31% des cas corrélée à la rupture médicamenteuse. Onze (11) patients ont présenté une infection confirmée à SARS CoV-2. Conclusion : La pandémie de covid-19 a eu un impact non négligeable sur le suivi des patients atteints de maladies inflammatoires systémiques. Elle a mis en exergue l'intérêt de la réorganisation de la prise en charge de ces patients en période de crise sanitaire, l'éducation thérapeutique des patients et le recours à la télémédecine pour assurer la continuité des soins.

Introduction: The covid-19 pandemic has had an impact on health systems, compromising the optimal management of chronic diseases such as systemic autoimmune and autoinflammatory diseases. The aim of our study was to assess its impact on the follow-up of systemic diseases in Dakar. Patients - Methods: We conducted a multicentre cross-sectional survey in the departments of Internal Medicine, Rheumatology and Nephrology in Dakar. Patients were included in accordance with international consensus criteria. The survey was based on records of 13 questions and was completed by a telephone interview with 38 potential questions. Responses were collected using a web-based application and then exported and analyzed using SPSS 26.0 software. Results: From 1 August to 31 October, 131 patients were included with a mean age of 41.5 years (+/-12.4) and a sex-ratio of 0.08. Inflammatory diseases were dominated by rheumatoid arthritis (47.3%) and systemic lupus erythematosus (22.9%). Patients reported missing one or more follow-up appointments in 45% of the cases. The reasons were dominated by difficulty in obtaining a follow-up appointment (18.6%) and fear of attending hospitals (16.9%). A drug shortage was also reported in 33.6% of the cases and concerned in particular hydroxychloroquine (40.9%) or methotrexate (47.7%), with the main reason being stock shortages in pharmacies and economic difficulties. A flare-up of the systemic disease was reported in 31% of the cases correlated with the drug rupture. Only 11 patients had a confirmed SARS CoV-2 infection. Conclusion: The covid-19 pandemic has had a significant impact on the follow-up of patients with systemic inflammatory diseases. It highlighted the interest of reorganizing the follow-up of these patients during a health crisis, the patient education and the use of telemedicine to ensure continuity of care

Facteurs associés à l'hospitalisation prolongée et à la mortalité au niveau du service de néphrologie de l'hôpital Aristide Le Dantec de Dakar / Factors associated with prolonged hospitalization and mortality in the nephrology department of the Aristide Le Dantec hospital in Dakar

Introduction : L'hospitalisation en néphrologie n'avait pas fait l'objet de plusieurs études au Sénégal et les données sont limitées. Notre travail avait pour but de déterminer les facteurs associés à l'hospitalisation prolongée et à la mortalité en néphrologie. Patients et méthodes : Il s'agissait d'une étude observationnelle prospective de 5 mois incluant tous les patients hospitalisés dans le service durant au moins 24H. La durée d'hospitalisation (la période allant du jour d'admission dans la chambre d'hospitalisation au jour de sortie du patient) était dite prolongée si > 12 jours. Résultats : Quatre-vingt-dix-neuf patients ont été analysés durant cette période avec une durée moyenne en hospitalisation de 11,14 ± 9,89 jours. L'âge moyen était de 45,22 ± 18,03 ans avec un sex-ratio (H/F) de 0,62. Les anomalies biologiques étaient : l'hyponatrémie (62,36%), l'hypokaliémie (23,91%), l'hypocalcémie (25%), l'hyperphosphatémie (51,21%), l'anémie (92,30%), la CRP élevée (90,90%) et l'hypoalbuminémie (80,76%). La protéinurie moyenne était de 3,38 ± 3,35 g/24h avec 34,61% de protéinurie néphrotique. La mortalité hospitalière était de 25,25%. En analyse univariée, l'hospitalisation prolongée était associée à l'âge ≤ 45 ans (p = 0,018), aux patients non dialysés chroniques (p=0,034), à la transfusion sanguine (p=0,008) tandis que la mortalité était liée à l'âge de plus de 45 ans (p=0,032), le diabète (p=0,014), l'hypokaliémie (p=0,045) et l'hospitalisation prolongé (p=0,007). En analyse multivariée, les patients présentant des œdèmes et ceux ayant été transfusés avaient respectivement 2,89 et 3,9 fois plus de risque d'avoir une hospitalisation prolongée. Les patients diabétiques avaient 4,63 fois plus de risque de décès et ceux ayant été hospitalisés de plus de 12 jours avaient 0,14 fois de risque de décès. Conclusion : La durée d'hospitalisation était relativement prolongée avec une mortalité élevée. Cependant l'impact de certains facteurs a été démontré permettant ainsi de réduire la durée d'hospitalisation et le nombre de décès.

Introduction: Hospitalization in nephrology had not been the subject of several studies in Senegal and the data are limited. Our work aimed to determine the factors associated with prolonged hospitalization and mortality in nephrology. Patients and methods: This was a 5-month prospective observational study including all patients hospitalized in the department for at least 24 hours. The duration of hospitalization (the period from the day of admission to the hospital room to the day of the patient's discharge) was said to be prolonged if > 12 days. Results: Ninety-nine patients were analyzed during this period with an average hospital stay of 11.14 ± 9.89 days. The mean age was 45.22 ± 18.03 years with a sex ratio (M/F) of 0.62. The biological abnormalities were: hyponatremia (62.36%), hypokalemia (23.91%), hypocalcemia (25%), hyperphosphatemia (51.21%), anemia (92.30 %), elevated CRP (90.90%) and hypoalbuminemia (80.76%). The mean proteinuria was 3.38 ± 3.35 g/24h with 34.61% nephrotic proteinuria. Hospital mortality was 25.25%. In univariate analysis, prolonged hospitalization was associated with age ≤ 45 years (p = 0.018), chronic non-dialysis patients (p = 0.034), blood transfusion (p = 0.008) while mortality was related to age over 45 (p=0.032), diabetes (p=0.014), hypokalaemia (p=0.045) and prolonged hospitalization (p=0.007). In multivariate analysis, patients with edema and those who had been transfused were respectively 2.89 and 3.9 times more likely to have prolonged hospitalization. Diabetic patients had a 4.63 times greater risk of death and those who had been hospitalized for more than 12 days had a 0.14 times greater risk of death. Conclusion: The duration of hospitalization was relatively prolonged with high mortality. However, the impact of certain factors has been demonstrated, thus making it possible to reduce the duration of hospitalization and the number of deaths

Ketamine pour la gestion de la douleur post hystérectomie au CHU Professeur Zafisaona Gabriel Mahajanga Madagascar / Ketamine for the management of post-hysterectomy pain at the Professor Zafisaona Gabriel University Hospital, Mahajanga, Madagascar

Une analgésie multimodale est incontournable pour la prise en charge de la douleur post opératoire. L'objectif de notre étude était de montrer l'intérêt de l'utilisation de la kétamine, avec son effet analgésique, parmi les différentes molécules disponibles. Méthodes : Il s'agit d'une étude prospective monocentrique en simple aveugle de 31 cas d'hystérectomie programmée sur une période de 6 mois (mai­octobre 2016) divisée en deux groupes soumis au même protocole anesthésique : un groupe recevant de la kétamine en bolus suivi d'une perfusion continue peropératoire et sur les premières 24 heures et un groupe contrôle sans kétamine. En période post opératoire les deux groupes bénéficient d'une analgésie multimodale. L'analyse statistique a été faite par le test de Student. Résultats : Les scores de douleur diffèrent peu en moyenne sur les 24 heures de surveillance, tandis qu'une épargne morphinique importante est notée dans le groupe kétamine de l'ordre de 50% avec une valeur de p<0,001 fortement significative. A côté nous n'avons constaté aucun effet indésirable notable. Conclusion : L'adjonction de kétamine même de brève durée dans la prise en charge de la douleur post opératoire a permis de baisser considérablement la consommation morphinique

Introduction : Le choc hypovolémique est une défaillance circulatoire aiguë et critique, mettant rapidement en jeu le pronostic vital. L'objectif de l'étude était de déterminer les aspects épidémio-cliniques et la prise en charge du choc hémorragique periopéraoire au centre hospitalier de Mahajanga. Méthodes : Il s'agit d'une étude rétrospective, descriptive, observationnelle et monocentrique réalisée dans le service de Réanimation Chirurgicale du CHU PZaGa de Mahajanga, sur une période de 52 mois. Les données socio-démographiques, les paramètres cliniques périopératoires, la prise en charge médico-chirurgicale, l'évolution et les retentissements organiques de l'état de choc hémorragique ont été les paramètres étudiés. Résultats : Nous avons collecté 6896 dossiers des patients, dont 70 cas de choc hémorragique ont été recensés (1,02%) pour tout type de chirurgie ; 62 dossiers ont été retenus dans l'étude. La majorité des cas était du genre féminin (87,10%). Les pathologies gynéco-obstétricales étaient la principale source de l'état de choc de (77,4%), dont 59,4% d'hémorragie du post-partum. L'insuffisance rénale aiguë était la principale atteinte viscérale (61%, n=38) suivie de 10% (n=6) des cas des troubles neurologiques. Tous les patients ont bénéficié d'une oxygénothérapie, et d'un remplissage vasculaire par des cristalloïdes et 3,2% ont eu des colloïdes. Les substances vasoactives utilisées étaient l'éphédrine 41,9%, suivie de l'adrénaline 27,4% et de la noradrénaline 17,7%. Vingt-sept virgule quarante pourcent de nos patients étaient décédés, et la cause la plus incriminée était la coagulopathie par défibrination. Conclusion: Les hémorragies obstétricales constituent la première cause de choc hémorragique ; le taux de mortalité reste encore élevé.

Introduction : Plus qu'un défi ou un enjeu, la chirurgie ambulatoire, constitue pour les pays en voies de développement une opportunité d'accroître l'accès aux soins. Elle est un concept d'organisation centrée sur le malade, basée sur la sélection des patients et des actes chirurgicaux afin d'assurer une qualité et une sécurité maximale de soins. Objectifs : Partager les résultats de notre expérience sur la chirurgie ambulatoire en orthopédie traumatologie et de déterminer les difficultés rencontrées lors de sa mise en place. Matériels et Méthodes: Il s'agit d'une étude prospective, descriptive et observationnelle allant de janvier 2018 au janvier 2019 (12 mois) réalisée au CHU Morafeno Toamasina. Résultats: Au total, 108 patients ont été retenus. Les interventions réglées étaient réalisées chez 82,40% des patients contre 17,59% d'urgences traumatologiques. L'âge moyen des patients était de 32 ans ± 8,6 ans avec une prédominance masculine (sex ratio:3,9) . Le type d'intervention réalisé était dominé par les ablations de matériels d'ostéosynthèses avec un taux de 25,92%, suivies des tentatives de réduction orthopédique de fractures dans 22,22 % des cas. Le type d'anesthésie la plus pratiquée était l'anesthésie locorégionale (52,77%). Les évènements en postopératoire étaient dominés par l'insomnie (4,62%), la céphalée (2,77 %), les nausées et vomissements (5,55%) et les hématomes (3,70%). Soixante-douze virgule deux pour cent des patients déclaraient satisfaits de leur prise en charge. Conclusion: Le développement extensif de la chirurgie ambulatoire est basé sur la sélection des patients à qui l'on propose ce type de prise en charge. Elle présente un enjeu majeur en matière de restructuration et d'amélioration de l'offre de soins en chirurgie orthopédique et traumatologie

The myocardial capillary network is altered in congenital diaphragmatic hernia in the fetal rabbit model

Congenital diaphragmatic hernia (CDH) is associated with thoracic compression of the lungs and heart caused by the herniated abdominal content, leading to cardiac modifications including pressure and vascular changes. Our aim was to investigate the experimental immunoexpression of the capillary proliferation, activation, and density of Ki-67, VEGFR2, and lectin in the myocardium after surgical creation of a diaphragmatic defect. Pregnant New Zealand rabbits were operated on the 25th gestational day in order to create left-sided CDH (LCDH, n=9), right-sided CDH (RCDH, n=9), and Control (n=9), for a total of 27 fetuses in 19 pregnant rabbits. Five days after the procedure, animals were sacrificed, and histology and immunohistochemistry studies of the harvested hearts were performed. Total body weight and heart weight were not significantly different among groups (P=0.702 and 0.165, respectively). VEGFR2 expression was increased in both ventricles in the RCDH group (P<0.0001), and Ki-67 immunoexpression was increased in the left ventricle in the LCDH group compared to Control and RCDH groups (P<0.0001). In contrast, capillary density was reduced in the left ventricle in the LCDH compared to the Control and RCDH groups (P=0.002). Left and right ventricles responded differently to CDH in this model depending on the laterality of the diaphragmatic defect. This surgical model of diaphragmatic hernia was associated with different expression patterns of capillary proliferation, activation, and density in the myocardium of the ventricles of newborn rabbits.

Immuno-oncology in head and neck squamous cell carcinoma - a narrative review

Immuno-oncology studies the immune system in cancer. In recent decades, immunotherapy has shown a good response to the treatment of various locally advanced and metastatic cancers. The main mechanisms of action include stimulation of the patient's own immune system to enhance immune responses acting in tumor escape pathways. This review examined the literature related to immune system mechanisms in head and neck squamous cell carcinoma (HNSCC) and their application in immunotherapy using biomarkers. The PUBMED, LILACS, MEDLINE, WHOLIS, and SCIELO databases were searched using the terms squamous cell carcinoma, head and neck, immuno-oncology, immunotherapy, and immunology. The main drugs currently available for clinical use in patients diagnosed with HNSCC include pembrolizumab and nivolumab, both classified as check-point inhibitors. These immunobiological agents improve patient survival and quality of life. Many authors and clinical trials point out that the recommendation of these agents is linked to the dose of PD-L1 (ligand expressed primarily by tumor cells), which proved to be an unreliable biomarker in the patient selection. Recommendation of immunotherapy depends on reliable biomarkers that must be identified in order to achieve good therapeutic results.

Influence of garlic extract on larval performance and survival of juvenile angelfish Pterophyllum scalare during transport / Influência do extrato de alho no desempenho larval e na sobrevivência durante o transporte de juvenis de acará bandeira Pterophyllum scalare

Abstract The objective of this study was to evaluate the properties of garlic as a growth promoter in larvae of angelfish Pterophyllum scalare and its benefits during transport of juveniles of this species. The experiment was conducted in recirculation aquaculture system, consisting of 20 tanks of 40 L equipped with independent water input and output. We used 1,400 larvae distributed among five treatments, with four repetitions, which totaled 20 experimental units. The treatments were 0, 50, 100, 200, and 400 mg of garlic extract per kilo of feed. The results showed that the inclusion of levels of garlic extract in the feed did not significantly effect the fish's development or their transport. Neither did the inclusion of levels of garlic extract affect the survival of the larvae during the trial period. New research with extracts of higher dosages should be performed to elucidate the effect of garlic extract as a growth promoter.

Resumo O estudo teve como objetivo avaliar as propriedades do alho como promotor de crescimento em larvas de acará bandeira Pterophyllum scalare e seus benefícios no transporte de juvenis da mesma espécie. O experimento foi conduzido em sistema de recirculação composto por 20 aquários de 40 L de volume útil, dotado de entrada e saída de água independentes e teve a duração de 40 dias. O delineamento experimental adotado foi o inteiramente casualizado (DIC), com cinco tratamentos e quatro repetições, totalizando 20 unidades experimentais. Foram utilizadas 1.400 larvas de acará bandeira (Pterophyllum scalare) divididas entre os tratamentos. Os tratamentos consistiram em: 0, 50, 100, 200 e 400 mg de extrato de alho por quilo de ração. Os resultados mostraram que não houve efeito significativo dos níveis de inclusão do extrato do alho sobre os índices zootécnicos avaliados e posteriormente no transporte dos juvenis. Também não foi observado influência na sobrevivência das larvas durante o período experimental.

Abstract Ri chicken is the most popular backyard chicken breed in Vietnam, but little is known about the growth curve of this breed. This study compared the performances of models with three parameters (Gompertz, Brody, and Logistic) and models containing four parameters (Richards, Bridges, and Janoschek) for describing the growth of Ri chicken. The bodyweight of Ri chicken was recorded weekly from week 1 to week 19. Growth models were fitted using minpack.lm package in R software and Akaike's information criterion (AIC), Bayesian information criterion (BIC), and root mean square error (RMSE) were used for model comparison. Based on these criteria, the models having four parameters showed better performance than the ones with three parameters, and the Richards model was the best one for males and females. The lowest and highest value of asymmetric weights (α) were obtained by Bridges and Brody models for each of sexes, respectively. Age and weight estimated by the Richard model were 8.46 and 7.51 weeks and 696.88 and 487.58 g for males and for females, respectively. Differences in the growth curves were observed between males and female chicken. Overall, the results suggested using the Richards model for describing the growth curve of Ri chickens. Further studies on the genetics and genomics of the obtained growth parameters are required before using them for the genetic improvement of Ri chickens.

Resumo O frango Ri é a raça de frango de quintal mais popular do Vietnã, mas pouco se sabe sobre a curva de crescimento dessa raça. Este estudo comparou o desempenho de modelos com três parâmetros (Gompertz, Brody e Logistic) e modelos contendo quatro parâmetros (Richards, Bridges e Janoschek) para descrever o crescimento do frango Ri. O peso corporal do frango Ri foi registrado semanalmente da semana 1 à semana 19. Os modelos de crescimento foram ajustados usando o pacote minpack.lm no software R e o critério de informação de Akaike (AIC); critério de informação bayesiano (BIC) e erro quadrático médio (RMSE) foram usados ​​para comparação de modelos. Com base nesses critérios, os modelos com quatro parâmetros apresentaram melhor desempenho do que os com três parâmetros, sendo o modelo de Richards o melhor para homens e mulheres. O menor e o maior valor dos pesos assimétricos (α) foram obtidos pelos modelos Bridges e Brody para cada um dos sexos, respectivamente. A idade e o peso estimados pelo modelo de Richard foram de 8,46 e 7,51 semanas e 696,88 e 487,58 g para homens e mulheres, respectivamente. Diferenças nas curvas de crescimento foram observadas entre frangos machos e fêmeas. No geral, os resultados sugeriram o uso do modelo de Richards para descrever a curva de crescimento de frangos Ri. Mais estudos sobre a genética e genômica dos parâmetros de crescimento obtidos são necessários antes de usá-los para o melhoramento genético de frangos Ri.

Influence of garlic extract on larval performance and survival of juvenile angelfish Pterophyllum scalare during transport / Influência do extrato de alho no desempenho larval e na sobrevivência durante o transporte de juvenis de acará bandeira Pterophyllum scalare

The objective of this study was to evaluate the properties of garlic as a growth promoter in larvae of angelfish Pterophyllum scalare and its benefits during transport of juveniles of this species. The experiment was conducted in recirculation aquaculture system, consisting of 20 tanks of 40 L equipped with independent water input and output. We used 1,400 larvae distributed among five treatments, with four repetitions, which totaled 20 experimental units. The treatments were 0, 50, 100, 200, and 400 mg of garlic extract per kilo of feed. The results showed that the inclusion of levels of garlic extract in the feed did not significantly effect the fish’s development or their transport. Neither did the inclusion of levels of garlic extract affect the survival of the larvae during the trial period. New research with extracts of higher dosages should be performed to elucidate the effect of garlic extract as a growth promoter.

O estudo teve como objetivo avaliar as propriedades do alho como promotor de crescimento em larvas de acará bandeira Pterophyllum scalare e seus benefícios no transporte de juvenis da mesma espécie. O experimento foi conduzido em sistema de recirculação composto por 20 aquários de 40 L de volume útil, dotado de entrada e saída de água independentes e teve a duração de 40 dias. O delineamento experimental adotado foi o inteiramente casualizado (DIC), com cinco tratamentos e quatro repetições, totalizando 20 unidades experimentais. Foram utilizadas 1.400 larvas de acará bandeira (Pterophyllum scalare) divididas entre os tratamentos. Os tratamentos consistiram em: 0, 50, 100, 200 e 400 mg de extrato de alho por quilo de ração. Os resultados mostraram que não houve efeito significativo dos níveis de inclusão do extrato do alho sobre os índices zootécnicos avaliados e posteriormente no transporte dos juvenis. Também não foi observado influência na sobrevivência das larvas durante o período experimental. Novas pesquisas com dosagens maiores de extratos devem ser realizados para melhor elucidação do efeito do extrato de alho como promotor de crescimento.

Liver-directed treatment is associated with improved survival and increased response to immune checkpoint blockade in metastatic uveal melanoma: results from a retrospective multicenter trial / 医学前沿

Metastases of uveal melanoma (UM) spread predominantly to the liver. Due to low response rates to systemic therapies, liver-directed therapies (LDT) are commonly used for tumor control. The impact of LDT on the response to systemic treatment is unknown. A total of 182 patients with metastatic UM treated with immune checkpoint blockade (ICB) were included in this analysis. Patients were recruited from prospective skin cancer centers and the German national skin cancer registry (ADOReg) of the German Dermatologic Cooperative Oncology Group (DeCOG). Two cohorts were compared: patients with LDT (cohort A, n = 78) versus those without LDT (cohort B, n = 104). Data were analyzed for response to treatment, progression-free survival (PFS), and overall survival (OS). The median OS was significantly longer in cohort A than in cohort B (20.1 vs. 13.8 months; P = 0.0016) and a trend towards improved PFS was observed for cohort A (3.0 vs. 2.5 months; P = 0.054). The objective response rate to any ICB (16.7% vs. 3.8%, P = 0.0073) and combined ICB (14.1% vs. 4.5%, P = 0.017) was more favorable in cohort A. Our data suggest that the combination of LDT with ICB may be associated with a survival benefit and higher treatment response to ICB in patients with metastatic UM.
