Objective: To analyze the therapeutic effect of costochondral graft (CCG) in constructing nasal tip cartilage composite for rhinoplasty. Methods: 84 rhinoplasty patients who were admitted to the hospital between September 2021 and September 2023 were selected and randomly grouped into a study group and a reference group of 42 cases each. The study group was prepared with CCG to construct a nasal tip cartilage composite and the reference group was filled with silicone material to compare the effectiveness of plastic surgery. Results: The plastic effect scores and the perioperative indexes of the study group were all higher than those of the reference group (P < 0.05). Before treatment, there was no difference in the nose-shaping indexes between both groups (P > 0.05). After treatment, the nasal plasticity indexes of the study group were all better than those of the reference group (P < 0.05). The complication rate of the study group was lower than that of the reference group (P < 0.05). Conclusion: The preparation of nasal tip cartilage composite using CCG improved the therapeutic effect of rhinoplasty, improved the perioperative indexes and nasal contouring indexes, and had fewer complications.

Introdução: As queimaduras representam um sério problema de saúde pública, com consequências que vão além das lesões físicas imediatas. As deformidades resultantes podem variar de cicatrizes discretas a alterações extensas no corpo do paciente. Essas deformidades não só afetam a aparência física, mas também a qualidade de vida e o bemestar emocional. Objetivo: Analisar o que se tem publicado acerca da aceitação da autoimagem por pacientes grande queimados. Metodologia: trata-se de uma pesquisa qualitativa, descritiva de revisão integrativa da literatura realizada na BVS. Os critérios de inclusão consideraram os artigos publicados no período de 2019 a 2024 e no idioma português, utilizando os descritores: Autoimagem, Enfermagem; Queimados. Foram selecionados e categorizados 3 artigos que após leitura na íntegra, gerou as seguintes categorias temáticas: Me reencontrando no mundo: os desafios da aceitação da autoimagem pós Queimaduras. Resultados: Foram encontrados 26 artigos que após leitura integral emergiu nas categorias temáticas: os principais desafios enfrentados pelo paciente grande queimado, o papel do enfermeiro na promoção da autoimagem. As lesões decorrentes das queimaduras provocam marcas físicas e mentais, influenciando nos aspectos sociais, emocionais. Conforme a extensão das cicatrizes, pode ocorrer distorções na autoimagem, podendo provocar mudanças na reabilitação social do indivíduo. Diante dos inúmeros desafios encontrados, é perceptível que o enfermeiro tem papel fundamental no resgate da autoestima dos pacientes em grande queimado. Conclusão: Estudos apontaram que grande partes de vítimas de queimaduras, são acometidas pela doença depressão, ao impacto da percepção da autoimagem. Com isso conclui-se que a família tem grande importância no processo de recuperação e fortalecimento dos laços familiares durante e após tratamento da queimadura. Por isso, é importante que o enfermeiro compreenda as dificuldades vivenciadas pela vítima, visando favorecer uma hospitalização mais confortável, tranquila e minimizar as sequelas.

Introduction. In recent years, fundamental research has appeared proving the important role of the level of sex hormones on the microbiota of the urogenital tract. Evidence has emerged that the level of testosterone and estradiol not only in the blood but also in the seminal plasma affects the functional parameters of sperm, as well as the course of chronic prostatitis and chronic pelvic pain syndrome.The study objective. To identify the influence of the level of sex hormones in blood serum and seminal plasma on the microbiota of ejaculate in healthy men.Material and methods. A prospective pilot study was conducted on 20 fertile male volunteers who applied for a preventive examination and did not present active complaints. All patients underwent a double study of the ejaculate by PCR real-time (Androflor®) test, as well as determination of the level of hormones in the blood serum: total testosterone, estradiol, progesterone, sex hormone binding globulin, calculation of the free androgen index and testosterone/estradiol ratio, in the seminal plasma of total testosterone and estradiol.Results. In more than half of the cases, anaerobes and opportunistic microorganisms were found in the sperm. In the ejaculate, the levels of total testosterone and estradiol were statistically significantly higher compared to blood serum; the testosterone/estradiol ratio was not statistically different in the blood and seminal plasma. A statistically significant indirect relationship was revealed between the level of testosterone in the blood serum and the value of total bacterial mass in semen (p<0.05). A statistically significant indirect relationship was observed between the level of testosterone in the blood serum and the presence of Atopobium cluster and Sneathia spp./Leptotrichia spp./ usobacterium spp. in semen. (р<0.05). A pronounced tendency was revealed for a lower frequency of occurrence of Enterobacteriaceae spp./Enterococcus spp. in the ejaculate at high levels of testosterone/estradiol ratio.Conclusion. The levels of testosterone and estradiol in blood serum and ejaculate are significantly different and do not always correlate with each other. Our study demonstrates the presence of a correlation between the level of testosterone in the blood serum and testosterone/estradiol ratio with the total bacterial mass in the ejaculate, which is evidence of the etiological significance of sex hormones in the development of bacteriospermia in men.

Explore the significant impact of alignment on the optical performance data and resulting technical specifications of augmented reality (AR) and virtual reality (VR) devices providing insights into the considerations necessary for optimal alignment strategies. The relevance of true eye geometry is highlighted in considering pupil rotation in instantaneous/wide field of view cameras compared to true eye rotation of the human eye as represented by an active gaze tracking and imaging platform.

Our knowledge of tumor-infiltrating lymphocytes (TILs) is dramatically expanding. These cells have proven prognostic and therapeutic value for many cancer outcomes and potential to treat also disseminated breast, colorectal, or lung cancer. However, the therapeutical outcome of TILs is negatively affected by tumor mutational burden and neoantigens. On the other hand, it can be improved in combination with checkpoint blockade therapy. This knowledge and rapid detection techniques alongside gene editing allow us to classify and modify T cells in many ways. Hence, to tailor them precisely to the patient´s needs as to program T cell receptors to recognize specific tumor-associated neoantigens and to insert them into lymphocytes or to select tumor neoantigen-specific T cells, for the development of vaccines that recognize tumor-specific antigens in tumors or metastases. Further studies and clinical trials in the field are needed for an even better-detailed understanding of TILs interactions and aiming in the fight against multiple cancers.

Most secondary school students in developing countries have difficulty accessing higher Education after completing secondary Education, especially in Indonesia. The limited number of new job opportunities and the absence of a link and match between the competencies possessed by the workforce and employment have triggered the high Open Unemployment Rate (TPT) of VHS graduates, especially in West Java.This research uses mixed methods where data collection is carried out quantitatively and qualitatively. In collecting quantitative data, respondents to this study used data from 341 vocational students at six vocational schools in 5 districts/cities in West Java. Then strengthened by qualitative methods by conducting interviews. First, the thing that most influences the low quality of competitiveness of VHS students is that 21.07% of VHS students in West Java have a low VHS objective score. Second, the Quality of Education, Entrepreneurial Mindset, and Entrepreneurial Intentions simultaneously influence the goals of VHS in West Java Vocational School students, with an F count of 135,773 with a significance level of 0.000. Third, 54.7% of the goals of VHS students in West Java are influenced by the Quality of Education, Entrepreneurial Mindset, and Entrepreneurial Intentions. At the same time, 45.3% is influenced by other variables not analyzed in this study. to increase the competitiveness of VHS students, it is necessary to carry out various intervention efforts starting from the stages of input, process, output, and long-term results in the learning process in schools.

Abstract Cancer curing immune responses against heterogeneous solid cancers require that a coordinated immune activation is initiated in the antigen avid but immunosuppressive tumor microenvironment (TME). The plastic, immunosuppressive TME, and the poor systemic tolerability of immune activating drugs are, however, fundamental barriers to generating curative anticancer immune responses. Here, we introduce the CarboCell technology to overcome these barriers by forming a sustained drug release depot at the injection site that provides high payloads of immune stimulatory drugs selectively within the TME. The CarboCell thereby induces a hot spot for immune cell training and polarization and further drives and maintains the tumor-draining lymph nodes in an anticancer and immune activated state. Mechanistically, this transforms cancerous tissues to allow infiltration of T cells, consequently generating systemic anticancer immunoreactivity. The CarboCell technology can release multiple small molecule drugs - each with tailored release profiles - rendering it active across the broad composition of TME backgrounds. In the current study, impressive therapeutic performance is presented for a dual-drug CarboCell providing sustained release of a Toll-like receptor 7/8 agonist and a transforming growth factor-β inhibitor. CarboCell can be injected through standard clinical thin-needle technologies. Its inherent magnetic resonance imaging and ultrasound visibility, and optional radiographic contrast, make it possible to validate and plan CarboCell injections across clinical imaging modalities. These features, in combination with attractive injection intervals, secure optimal patient compliance and open new possibilities for intratumoral immunotherapy accurately across basically all anatomical locations.
