The role of neophobia in a pioneer olfactory enrichment for amazons, macaws, and toucans / El papel de la neofobia en un enriquecimiento olfativo pionero para guacamayos, loros y tucanes

Abstract Introduction: Despite sensory enrichment being critical for ensuring the well-being of captive wild animals, smells are not being included in enrichment protocols for birds. For this group, neophobia can be a problem when it comes to implementing new enrichment devices. Objective: To explore how participation in an olfactory enrichment and latency times varies between bird taxonomic groups (Amazona spp. / Ara spp. / Ramphastos spp.). Methods: We exposed 257 birds to a scent enrichment, and we recorded which individuals engaged with it and the time they took to interact with it. Results: We discovered that participation by toucans in the enrichment was higher compared to amazons and macaws. Furthermore, latency time to interact with the enrichment was higher in amazons that in the other species. Our findings could suggest that toucans are neophilic species which could benefit from higher exploration rates. Amazons on the contrary seem to be particularly neophobic, possibly because of their less opportunistic feeding habits compared to toucans and their higher vulnerability to predation compared to macaws. Conclusion: These results point out that toucans would be more inclined to engage in environmental enrichments, while a more natural design using smells inside familiar objects could be a more successful enrichment for psittacids.

Resumen Introducción: A pesar de que el enriquecimiento sensorial es fundamental para garantizar el bienestar de los animales silvestres en cautiverio, los olores no son incluidos de forma rutinaria en los protocolos de enriquecimiento para aves. Además, en el caso de estos animales, la neofobia puede ser un problema a la hora de implementar nuevos dispositivos de enriquecimiento. Objetivo: Explorar cómo varía la participación y la latencia en la interacción con un enriquecimiento olfativo entre grupos taxonómicos de aves (Amazona spp. / Ara spp. / Ramphastos spp.). Métodos: Expusimos a 257 aves a un enriquecimiento olfativo y registramos qué individuos participaron y el tiempo que tardaron en interactuar con él. Resultados: La participación en el enriquecimiento fue mayor en los tucanes en comparación con las amazonas y los guacamayos. Además, el tiempo de latencia para interactuar con el enriquecimiento fue mayor en las amazonas que en las otras especies. Nuestros hallazgos sugieren que los tucanes son especies neofílicas que podrían beneficiarse de tasas de exploración más altas. Por otro lado, las amazonas parecen ser particularmente neofóbicas, posiblemente debido a sus hábitos alimenticios menos oportunistas en comparación con los tucanes y a su mayor vulnerabilidad a la depredación en comparación con los guacamayos. Conclusión: Estos resultados señalan que los tucanes serían más proclives a participar en enriquecimientos ambientales, mientras que un diseño que utilice olores dentro de objetos más naturales o familiares podría ser más exitoso para las psitácidas.

Evaluación de las Lesiones Orofaciales y Traumatismos Dentales en Deportes de Combate y no Combate

Los deportes de combate conllevan un alto riesgo de padecer traumatismos dentoalveolares. Este estudio se evaluó la incidencia de traumatismos y lesiones orofaciales relacionadas con los deportes de combate, junto con la evaluación de las actitudes y hábitos de los deportistas respecto al uso de protectores bucales. Este estudio se realizó mediante sistema de encuestas digitales distribuidas en diferentes clubes deportivos donde se practican deportes de combate y no combate. Los deportistas de combate tienen más probabilidad sufrir alguna lesión orofacial que los no deportistas de combate. El sexo masculino y la experiencia son factores predisponentes en la aparición de traumatismos y lesiones orofaciales, siendo las laceraciones de tejidos blandos las más frecuentes. Los deportistas de combate llevan más protectores bucales que los deportistas en general, siendo el protector tipo II el más usado. Los deportistas que no llevan protectores no consideran que sea necesario. En caso de sufrir una avulsión dental, la mayoría de los participantes consideran que es posible reimplantar un diente avulsionado.

Combat sports carry a high risk of suffering dentoalveolar trauma. This study evaluated the incidence of dentoalveolar lesions related to combat sports, together with the evaluation of athletes' attitudes and habits regarding the use of mouth guards. This study was carried out using a digital survey system distributed in different sports clubs where combat and non-combat sports are practiced. Combat athletes are more likely to suffer a dentoalveolar lesion than non-combat athletes. Male sex and experience are predisposing factors in the appearance of dentoalveolar lesions, with soft tissue lacerations being the most frequent. Combat athletes wear more mouth guards than athletes in general, with the type II protector being the most used. Athletes who do not wear protectors do not consider it necessary. In case of suffering a dental avulsion, most of the participants consider that it is possible to reimplant an avulsed tooth.

Advancement in Tissue Culture Techniques for Fruit Crops

Tissue culture is a highly promising approach that enables the efficient propagation of many plants from tiny fragments of the parent plant within a relatively brief timeframe and confined area. Tissue culture, a contemporary approach, is primarily employed for the efficient and extensive replication of many commercially significant plant species, such as the date palm. Utilizing the tissue culture technique presents a potential approach for generating a substantial quantity of genetically homogeneous palm plants that resemble other plants and yield typical fruit within four years from initial planting. Furthermore, this technique allows to produce date palm plants devoid of diseases, exhibiting an exceptionally high survival rate of nearly 100% when compared to the traditional vegetative propagation of shoots, owing to the robustness of their root system. The process of surface sterilization holds significant importance in the production of explants for in vitro studies, as it effectively addresses the issue of bacterial and fungal contamination originating from field sources, which might vary considerably across different fruit plant species. The efficacy of tissue culture techniques for date palm acclimatization in vitro is contingent upon the observation of leaf count prior to transplantation in the greenhouse. Hence, the primary objective of this study was to investigate the determinants that govern the tissue culture of fruit trees. India is known for being the native land of various fruit crops that are both significant and minor in terms of their importance. These crops include Indian gooseberry (Emblica officinalis Gaertn.), Karonda (Carissa carandas L.), Bael (Aegle marmelos Corr.), Jamun (Syzygium cuminii L.), and jackfruit (Artocarpus heterophyllus L.), etc. These fruits possess considerable nutritional, medicinal, and therapeutic value, making them highly valuable in commercial sectors such as medicine, food, and cosmetics. The limited availability of suitable planting materials imposes constraints on the commercial production process for these crops. Using plant tissue culture techniques holds promise in substantially augmenting the number of novel cultivars or genotypes inside fruit crops. The primary aim of this review study is to consolidate and synthesize the extant body of knowledge about the tissue culture techniques employed in cultivating various fruit crops.

A Comprehensive Review on Role of Plant Tissue Culture in Ornamental Crops: Cultivation Factors, Applications and Future Aspects

Resumen Antecedentes: El tratamiento de la infección crónica por el virus de la hepatitis C (VHC) con antivirales de acción directa logra tasas de respuesta virológica sostenida superiores a 95 %. Sin embargo, el manejo del fracaso virológico sigue siendo un desafío clínico y la evidencia sobre el retratamiento es limitada, especialmente en poblaciones como los receptores de trasplante hepático (TH). Objetivo: Este estudio evaluó el régimen de sofosbuvir más glecaprevir/pibrentasvir (GLE/PIB) en receptores de TH en quienes falló el régimen basado en inhibidores de la proteína no estructural 5A (NS5A). Material y métodos: Estudio retrospectivo de 111 pacientes trasplantados entre enero de 2018 y diciembre de 2020; 18 pacientes presentaron infección recurrente por VHC posterior al TH, tres de ellos tuvieron antecedentes de al menos un régimen basado en inhibidores de NS5A. Se inició terapia de rescate con sofosbuvir más GLE/PIB durante 12 semanas posterior al TH; se registraron las características basales de los pacientes y sus desenlaces. Resultados: En los tres pacientes se logró obtener una carga viral indetectable de VHC a las 12 semanas de finalizar el tratamiento. No se observaron eventos adversos graves. Conclusión: En nuestra serie, sofosbuvir más GLE/PIB durante 12 semanas demostró ser una terapia de rescate efectiva y segura posterior al TH en pacientes previamente tratados con inhibidores de NS5A.

Abstract Background: Treatment of chronic hepatitis C virus (HCV) infection with direct-acting antivirals achieves a sustained virologic response rates higher than 95%. However, virologic failure remains a clinical challenge, and data on retreatment are limited, especially in special populations such as liver transplant (LT) recipients. Objective: This study evaluated the sofosbuvir plus glecaprevir-pibrentasvir (GLE/PIB) regimen in LT recipients who had failed to a nonstructural protein 5A (NS5A) inhibitor-based regimen. Material and methods: Retrospective study of 111 liver transplant recipients between January 2018 and December 2020; 18 patients presented with HCV recurrent infection after LT, out of whom three had a history of at least one NS5A inhibitor-based regimen. Salvage therapy with sofosbuvir plus GLE/PIB was started for 12 weeks; baseline characteristics and outcomes were recorded. Results: All three patients (100%) achieved an undetectable HCV viral load 12 weeks after treatment completion. No serious adverse events were observed. Conclusion: In our series, sofosbuvir plus GLE/PIB for 12 weeks is an effective and safe salvage therapy after LT in patients previously treated with NS5A inhibitors.

Background: The study aims to evaluate whether instillation of levo-bupivacaine intraperitoneally decreases post-operative pain after laparoscopic gynaecological surgeries, using VAS pain Scale.Methods: Randomized placebo controlled double blinded study conducted at tertiary care hospital in New Delhi. 90 ASA I & II women scheduled to undergo elective laparoscopic gynaecological surgeries. 20 ml 0.5% levo-bupivacaine diluted with 40ml normal saline (total 60ml) intraperitoneally at the end of surgery before closure of ports along with port site infiltration of levo-bupivacaine (3-5 ml) in intervention group and 60 ml normal saline intraperitoneally in control group.Results: Mean pain scores were significantly lower (p<0.01) in the intervention group when compared to the control group for initial 4 hours of the study after that mean pain score was lower in intervention group than control group but it was statistically not significant. The requirement of rescue analgesia was also significantly lesser in intervention group compared to control group.Conclusions: Levo-bupivacaine is an easy, cheap and non-invasive method which provides good analgesia in the immediate postoperative period after laparoscopic gynaecological surgery, without adverse effects, especially in the early postoperative period. This improves patients experience and should be made an integral part of all minimal gynaecological endoscopic surgery.

Effect of elective cerclage versus rescue cerclage in pregnancy and its pregnancy outcome

Prolongation of the pregnancy in cases of incompetence of cervix or short cervix can be done by prompt diagnosis at the correct time with a decision on encirclage taken at the right time. An observational retrospective study conducted over a period of 6 months in a tertiary care centre enrolling 14 pregnant women who had various risk factors like multiple gestation, short cervix, cervical incompetence, bad obstetric history, anomalous uterus, in vitro fertilization technique, history of primary infertility ,recurrent abortions and mid-trimester losses or preterm delivery, and the results were interpreted with various tables and charts showing the benefits of elective versus emergency encirclage. Through the study, it was found that there wasn't any significant difference in the incidence of a patient who underwent cervical encirclage whether the patient had a prior antenatal registration or not. 71% of the patients enrolled for encirclage were primigravida and the most common gestation age was between 12-24 weeks. The most common age group was 21-30 years of age. Cervical incompetence and short cervix were the most important risk factor needed for cervical cerclage. Most of the patients delivered at around 34-37 weeks of gestation. 21.4% patient underwent rescue cerclage and delivered between 34-37 weeks of gestation. 57.14% underwent elective cerclage and delivered near term. Elective cerclage has a better outcome of pregnancy to reach near term than rescue cerclage.

Strategies and methods of monitoring and rescue of DIEP flap in breast reconstruction (with video) / 中华内分泌外科杂志

Autologous tissue reconstruction accounts for a certain proportion in immediate or delayed breast reconstruction. Deep infra-epigastric perforator free flap has its significant advantages, gradually being widely promoted and applied in China. The success rate of DIEP surgery is generally over 95%. However, vessel crisis and flap necrosis are inevitable. Before surgery, personnel and equipment should be prepared and patients should be thoroughly evaluated. During the surgical process, it is necessary to follow certain programmed and standardized procedures. Meticulous manipulations through entire operation are the key to reduce the risk of vessel crisis. Standard of procedure for flap monitoring during and after surgery should be established, and strictly implemented. If vessel crisis occurs, timely and orderly organization, exploration, and rescue should be carried out. The surgical team should do their best to identify problems, and rescue the flap as much as possible. Ensuring the overall safety and reducing interference with subsequent adjuvant treatment for patients should be considered. Based on the author’s long-term and extensive clinical work experience, this paper shares and discusses the strategies and methods of monitoring and rescue of free flap in breast reconstruction.

Oral acetaminophen or high-dose ibuprofen as rescue treatment for very preterm infants with patent ductus arteriosus / 中国新生儿科杂志

Objective:To study the efficacy and safety of oral acetaminophen or high-dose ibuprofen as rescue treatment after failure of conservative management in very preterm infants (VPIs) with haemodynamically significant patent ductus arteriosus (hsPDA).Methods:From May 2020 to November 2022, VPIs with hsPDA (gestational age<32 weeks and age 4~6 d) admitted to NICU of our hospital were prospectively enrolled. The rescue treatment was initiated if hsPDA still exist after 3~4 d of conservative management. The infants were randomly assigned into acetaminophen group (oral acetaminophen 15 mg/kg, once every 6 h for 3 d) and high-dose ibuprofen group (oral ibuprofen 20 mg/kg for the first dose, 10 mg/kg each dose after 24 h and 48 h). Before and after rescue treatment, the following were recorded: echocardiography, complete blood count, biochemistry, B-type natriuretic peptide (BNP), fecal occult blood test (FOBT) and transcranial Doppler ultrasound. Urine output and complications were also examined. SPSS 20.0 was used for statistical analysis.Results:A total of 36 cases were in the acetaminophen group and 37 in the high-dose ibuprofen group. The two groups showed similar efficacy as rescue treatment [80.6% (29/36) vs. 78.4% (29/37), P>0.05]. No significant differences existed in the incidences of upper gastrointestinal bleeding, positive FOBT, oliguria, stage Ⅱ-Ⅲ necrotizing enterocolitis and stage Ⅲ-Ⅳ intraventricular hemorrhage between the two groups ( P>0.05). After rescue treatment, the serum cystatin C in high-dose ibuprofen group was higher [(1.72±0.29) mg/L vs. (1.58±0.26) mg/L] and 24-hours urine output was lower [(3.1±1.0) ml/(kg·h) vs. (3.7±0.7) ml/(kg·h)] than the acetaminophen group (all P<0.05). No significant differences existed in serum creatinine, platelet count, BNP, alanine aminotransferase and total serum bilirubin between the two groups ( P>0.05). Conclusions:After failure of early conservative management in VPIs with hsPDA, when initiated within 7-10 d after birth, rescue treatment with oral acetaminophen or high-dose ibuprofen has a similar efficacy of 80%, and both drugs are safe. Oral high-dose ibuprofen may have a greater effect on renal function than acetaminophen.
