ABSTRACT

This study sought to identify the Social Representations of Obesity among 15 individuals who underwent bariatric surgery through the Roux-en-Y Gastric Bypass (RYGB) method and were subjected to Argon Plasma Coagulation (APC) due to weight relapse. Data were collected through interviews and analyzed via Descending Hierarchical Classification. Obesity was associated with physical limitations and difficulties in social relationships. Prejudice and difficulty in changing habits are associated with the choice to undergo surgical treatment and to weight relapse. The suffering that goes along with obesity and the difficulty in changing habits seem to be associated with the search for surgical help.


Este estudo procurou identificar as representações sociais da obesidade entre 15 indivíduos submetidos à cirurgia bariátrica pelo método Bypass Gástrico em Y de Roux (RYGB) e submetidos à Coagulação por Plasma de Argônio (APC) devido à recidiva de peso. Os dados foram coletados através de entrevistas e analisados por meio da Classificação Hierárquica Descendente. A obesidade foi associada a limitações físicas e dificuldades nas relações sociais. Preconceito e dificuldades na mudança de hábitos estão associados à escolha de se submeter a tratamento cirúrgico e à recidiva de peso. O sofrimento que acompanha a obesidade e a dificuldade de mudar hábitos parecem estar associados à busca de ajuda cirúrgica.


Este estudio buscó identificar las representaciones sociales de la obesidad entre 15 individuos que se sometieron a cirugía bariátrica utilizando el método de bypass gástrico Roux-en-Y (RYGB) y que se sometieron a coagulación con plasma de argón (APC) debido a una recaída en el peso. Los datos fueron recolectados a través de entrevistas y analizados utilizando la Clasificación Jerárquica Descendente. La obesidad se asoció con limitaciones físicas y dificultades en las relaciones sociales. Los prejuicios y las dificultades para cambiar los hábitos están asociados con la opción de someterse a un tratamiento quirúrgico y una recaída del peso. El sufrimiento que acompaña a la obesidad y la dificultad para cambiar los hábitos parecen estar asociados con la búsqueda de ayuda quirúrgica.

ABSTRACT

ABSTRACT Introduction: In several conditions, outcome stability is a great challenge for Orthodontics. Previous studies have reported that relapse commonly occurs along the years after orthodontic treatment finishing. Objective: The aim of the present study was to evaluate in the long-term transversal dental arch changes of Class II division 1 patients treated with cervical headgear and fixed appliance. Methods: Plaster study casts of 20 patients treated with cervical headgear without dental extractions were 3D-scanned and evaluated in three distinct times: initial (T1), immediate post-treatment (T2) and long-term retention (T3 - minimum 20 years). Transversal teeth distance of maxillary and mandibular canines, premolars and first molars were measured. Results: A statistically significant increase during treatment was observed for all maxillary teeth transversal distances (p< 0.05). In turn, a significant reduction was observed in the long term (p<0.05). For the mandibular teeth, canine transversal distance presented statistically significant constriction in the retention period (p<0.05). Mandibular first molars distance was significantly expanded by treatment (p<0.05) and remained stable in the long term. The changes observed for the other teeth or other times were considered not statistically relevant. Conclusions: For the accessed sample, transversal changes occurred during treatment and retention phases in Class II division 1 patients treated with cervical headgear and fixed appliance. Relapse was considered statistically relevant, even with the institution of a retention protocol.


RESUMO Introdução: Em várias condições, a estabilidade dos resultados é um grande desafio para a Ortodontia. Estudos prévios relataram que a recidiva ocorre, comumente, ao longo dos anos, após o término do tratamento ortodôntico. Objetivo: O objetivo da presente pesquisa foi avaliar as alterações transversais da arcada dentária em longo prazo de pacientes Classe II, divisão 1, tratados com aparelho extrabucal cervical e aparelho fixo. Métodos: Modelos de gesso de 20 pacientes tratados com AEB cervical, sem extrações dentárias, foram escaneados e avaliados em três momentos distintos: inicial (T1), pós-tratamento imediato (T2) e acompanhamento de longo prazo (T3, mínimo de 20 anos). A distância transversal entre os caninos superiores e inferiores, pré-molares e primeiros molares foi medida. Resultados: Foi observado aumento estatisticamente significativo durante o tratamento para todas as distâncias transversais dos dentes superiores (p < 0,05). Por sua vez, foi observada redução significativa em longo prazo (p < 0,05). Para os dentes inferiores, a distância transversal intercaninos apresentou constrição estatisticamente significativa no período de contenção (p < 0,05). A distância dos primeiros molares inferiores aumentou significativamente com o tratamento (p < 0,05) e permaneceu estável em longo prazo. As alterações observadas para os outros dentes ou outros tempos foram consideradas sem significância estatística. Conclusões: Para a amostra estudada, as alterações transversais ocorreram durante as fases de tratamento e contenção em pacientes Classe II, divisão 1, tratados com aparelho extrabucal de tração cervical e aparelho fixo. A recidiva foi considerada estatisticamente significativa, mesmo com a instituição de um protocolo de contenção.

ABSTRACT

@#Condylar displacement can lead to temporomandibular joint (TMJ) symptoms and relapse after orthognathic surgery. To minimize condylar displacement, numerous condylar positioning techniques have been applied in clinical practice. To verify the effectiveness of condylar positioning techniques in preventing postoperative TMJ symptoms and relapse, we reviewed the literature related to all types of intraoperative condylar positioning techniques in the past 20 years. According to a literature review, positioning techniques aim to seat the condyles at a preoperative position during surgery and are divided into noncomputer-aided and computer-aided condyle positioning methods. At present, computer-aided design/computer-aided manufacturing condylar positioning devices (CAD/CAM CPDs) are the most superior positioning methods and are composed of teeth-supported and bone-supported guidance. The sequence of the remaining technology positioning effect from high to low is as follows: CAD/CAM titanium plate positioning > manual positioning > computer-aided navigation system > image positioning system. Different techniques reach considerable accuracy within 1-2 mm and 1°-2° in locating the preoperative condylar position and preventing TMJ symptoms or disorders and surgical relapse to provide a clinical reference for different levels of surgeons and cases. However, this study lacks randomized controlled trials with large samples and long-term follow-up. Future studies should upgrade the current methods, improve the clinical utility, and develop new positioning techniques.

ABSTRACT

OBJECTIVE@#To analyze the efficacy of children with B-cell acute lymphoblastic leukemia (B-ALL) without prognostic fusion genes treated by CCLG-ALL 2008, and investigate the related factors affecting the recurrence of the patients.@*METHODS@#B-ALL patients without prognostic fusion genes treated by the protocol of CCLG-ALL 2008 in our hospital from March 2008 to December 2012 were retrospectively analyzed. Follow-up time was ended in August 31, 2019. The median follow-up time was 92 months (range 0-136 months). Kaplan-Meier was used to detect the RFS, and COX multivariate regression analysis was employed to identify the independent factors affecting the recurrence of the patients.@*RESULTS@#There were 140 males and 99 females enrolled in this study. The ratio of male to female was 1.41∶1. The median age was 4.4 years old and the median number of WBC at initial stage was 4.98×109/L. There were 77 cases relapsed during the observation while 162 without relapsed, 16 cases lost to follow-up and 72 cases died. The recurrence and mortality rate was 32.22% and 30.1%, respectively, in which 45 cases died of recurrence (62.5% of the total deaths). Univariate analysis showed that the age≥6 years old, WBC >100×109/L, the bone marrow blasts on day 15≥25%, the bone marrow minimal residual disease (MRD) at week 12 >10-4, and the higher risk were the main factors affecting the recurrence of the patients (P<0.05). Multivariate COX regression analysis showed that age≥6 years old, WBC >100×109/L, bone marrow MRD >10-4 at the 12th week were the independent risk factors affecting recurrence of the patients.@*CONCLUSION@#Age, initial WBC, and bone marrow MRD at the 12th week were correlated with recurrence in children with B-ALL without prognostic fusion genes, which can be used as prognostic indices of recurrence risk in clinical.

ABSTRACT

@#AIM: To evaluate the efficacy of mycophenolate mofetil(MMF)on the prevention of relapse and visual prognosis of patients in neuromyelitis optica spectrum disorders(NMOSD)with AQP4 antibody positive optic neuritis. <p>METHODS: We retrospectively reviewed 11 patients with initial diagnosis of NMOSD and AQP4 antibody positive optic neuritis from January 2017 to December 2019. Among the 11 patients, 3 were male and 8 were female. The unique core clinical manifestation of NMOSD was optic neuritis. The onset age was 36.3±6.0(27-47)years old. Duration of the disease was 3.4±1.4(2.2-6.8)a. MMF was added in the relieving period of NMOSD for 1a or over 1a. Annualized relapsing rate(ARR), best corrected vision activity(BCVA)and adverse reactions of MMF were recorded.<p>RESULTS: The median time of MMF treatment was 18(12, 36)mo. The ARR was 0.66/a at baseline and 0.16/a after the treatment. There were 91% of the patients had decreased ARR and 82% of them had no clinical relapse. The patients had significant improvement on ARR after MMF treatment(<i>P</i><0.05 ). In total, there was no significant difference between the mean BCVA after treatment and that at baseline(<i>P</i>>0.05). Of the 11 patients, 3 patients had side effects(27%), including 1 patient with elevated liver transaminase(9%), and 2 patients with mild gastrointestinal reaction(18%)during follow-up period. None of them discontinued MMF due to adverse events.<p>CONCLUSION: MMF treatment for AQP4 antibody positive NMOSD can reduce the ARR of optic neuritis to a certain extent and protect the visual function of patients.

ABSTRACT

Abstract Introduction: To date, many studies have validated the Hematopoietic Cell Transplantation Specific Comorbidity Index (HCT-CI) scoring system in allogeneic hematopoietic stem cell transplantation (allo-HSCT), but studies from developing countries remain scarce. Objective: The aim of this study was to evaluate and categorize Mexican patients using the HCT-CI at a referral center. Methods: One hundred and nineteen consecutive patients undergoing allo-HSCT at the National Institute of Medical Sciences and Nutrition in Mexico City were included. Patients were classified according to the HCT-CI scores. Results: The median age was 31 years and most were males (56%). Most patients had hematological malignancies (73%) and a low HCT-CI score (72%). The non-relapse mortality and survival were predicted according to the score. Conclusions: This is one of the few studies to evaluate the HCT-CI in adults with HLA-matched donors in a developing country and our findings suggest that the high percentage of patients with a low HCT-CI scores, contrary to international reports, could be explained by different comorbidities and demographics, but mainly due to stricter filters applied to HSCT candidates and consequently, a potential selection bias caused by limited resources.

ABSTRACT

Background: Central nervous system international prognosis index (CNS-IPI) is validated in European and the USA cancer databases. However, no validation has been done in Mexican population. Objective: The objective of the study was to assess the impact of the CNS-IPI on central nervous system (CNS) relapse and survival in Mexican patients with diffuse large B-cell lymphoma (DLBCL). Methods: In this retrospective analysis, clinical, biochemical, and histological variables and the CNS-IPI were analyzed. Results: Six hundred and forty-two patients with DBLCL were included in the study. The mean ± SD age was 56.8 ± 14.9 years. Most had an ECOG of 0-1: 75% (n = 484) had absence of B-symptoms and advanced disease (clinical stage: III-IV, n = 433, 67.4%). According to the CNS-IPI, almost one-half were in the low-risk category. According to the CNS-IPI, CNS relapse rate was 1.36% (95% CI: 83.2-92.8), 3.1% (95% CI: 132.4-162.8), and 7.4% (95% CI 61-91) for patients in the low-, intermediate-, and high-risk categories, respectively. The median overall survival in the high-risk group (CNS-IPI) was 22 months, and it has not been achieved after 80 months of follow-up for the other groups. Conclusions: CNS-IPI was associated with survival; therefore, we propose its use as a prognostic tool for prospective validation.

ABSTRACT

Abstract Background: Pemphigus foliaceus is exceedingly rare around the world, except within the few regions where it occurs as an endemic variant. Various factors can trigger immune mechanisms that induce pemphigus foliaceus or worsen its course. Objective: To determine the demographic and clinical characteristics of the patients with pemphigus foliaceus in a large series from a non-endemic country, investigate the triggering factors, and seasonal patterns. Methods: The data of the patients diagnosed with pemphigus foliaceus in the study's center between 1989-2018 were retrospectively analyzed. Results: Sixty-eight patients (mean age, 45.7 ± 14.5 years) were included in the study. The number of onsets reached its peak in spring-summer (p = 0.008). A total of 117 relapses occurred in 42 patients and were most common in spring-summer (not significant). Specific trigger factors were detected in 45 relapses. In the other 72 relapses, the peak was observed in spring-summer (p = 0.005). There were no significant differences in the demographic and clinical variables investigated between relapsed and non-relapsed patients. Study limitations: Retrospective design. Conclusions: Triggering factors could not be identified in more than half of the relapses in the study's series. The subgroup of relapses (without identified causes), as well as the onsets of the disease, showed a significant seasonal variation with a peak in spring-summer; however, the seasonal variable did not justify the total group of relapses. Although the seasonal variation may be caused by a combination of factors, UV radiation should be considered a trigger factor for the peaks in spring-summer, particularly in Turkey.

ABSTRACT

SUMMARY OBJECTIVE: Pulmonary metastasectomy for the treatment of metastatic colorectal cancer is essential, but high ranked evidence of survival benefit is lacking. Here, we aimed to examine the prognostic factors after pulmonary metastasectomy in patients with colorectal cancer. METHODS: This is a single-center, retrospective hospital-based observational case series study. We reviewed data for 607 patients with metastatic colorectal cancer (mCRC) who were treated and observed from 2012 to 2019. Of the 607 patients with mCRC, 87 were with solitary lung metastases. Of the 87 patients, 39 were not appropriate for metastasectomy, while 15 patients recognized as suitable candidates by the multidisciplinary thoracic tumor board rejected metastasectomy. Consequently, only 33 patients were included in the final analysis. RESULTS: Rectum was detected as the primary site in 16 (48.5%) patients. Over 80% of patients had metachronous lung metastases, with a median of 29.0 months from initial diagnosis. Video-assisted thoracic surgery with wedge resection was performed in 20 (60.6%) patients. Over 90% of patients had solitary metastasis resected, with 97% of R0 resection. Median tumor size was 23.0 mm (min: 10; max: 90). Adjuvant treatment was given to 31 (93.9%) patients, while neoadjuvant treatment was given only to 8 (25%) patients. Of the 33 patients, there were 25 (75.7%) relapses. The most frequent site of relapse was lung in 15 (45.5%) patients. Interestingly, there were only 4 (12.2%) patients who had a relapse in the liver after lung metastasectomy. We found that median disease-free survival (DFS) and overall survival (OS) were 43.0 (13.0-73.0) and 55.0 (31.6-78.4) months, respectively. CONCLUSIONS: Pulmonary metastasectomy was associated with significantly long-time survival rates in mCRC (43 months of DFS and 55 months of OS). The second relapse occurred in 25 (75.7%) patients, with isolated lung metastases in nearly half of the patients (45.5%). Therefore, lung metastases in mCRC were unique and a multidisciplinary team including a thoracic surgeon should manage these patients.

ABSTRACT

Resumen Los tumores de células germinales (TCG) son las neoplasias malignas más comunes y afectan especialmente a hombres jóvenes de 15 a 35 años de edad. Los pacientes con estadios 2 y 3 que recaen ofrecen un gran reto para el tratamiento inicial de la primera recaída. La terapia óptima para estos pacientes depende de su tratamiento inicial y está pobremente definida. Las opciones incluyen regímenes de segunda línea de quimioterapia a dosis convencionales que combinan cisplatino e ifosfamida, con vinblastina, etopósido o paclitaxel, o quimioterapia de altas dosis con soporte de células madre. En vista de que todavía no hay evidencia concluyente en los ensayos clínicos, las indicaciones para el uso de quimioterapia de altas dosis permanecen poco claras y se basan en estudios fundamentalmente retrospectivos. El tratamiento en la segunda recaída debe individualizarse según el paciente y el tratamiento previo. La resección quirúrgica de masas residuales luego de la quimioterapia es un elemento clave para una terapia exitosa en pacientes con marcadores tumorales negativos. Actualmente, en Venezuela los pacientes que presentan recaídas deben recibir tratamiento con cualquiera de los regímenes establecidos que se utilizan a dosis convencionales en segunda línea. En algunos casos, los pacientes deben recibir tratamiento en centros de oncología con un manejo multidisciplinario que permita el acceso a tratamiento con altas dosis de quimioterapia y a cirujanos oncólogos expertos en esta patología.


Abstract Germ cell tumors (GCT) are the most common malignant neoplasms affecting young men aged 15 to 35 years. Patients with previous stage 2 and 3 who relapse offer a great challenge to the Medical team. The optimal therapy for these patients with recurrent disease is still poorly defined. Options include second-line chemotherapy regimens at conventional doses which combine cisplatin and ifosfamide, with vinblastine, etoposide or paclitaxel, or alternatively high-dose chemotherapy with stem cell support. As there is still no conclusive evidence from clinical trials, the indications for the use of high-dose chemotherapy remain unclear. Most of the present literature is based in retrospective studies. Second relapse treatment options should be individualized according to the patient and his previous treatment. Surgical resection of residual masses in patients with negative markers after chemotherapy is a key element for successful therapy. Currently, patients in Venezuela who have relapses should receive treatment with any of the established regimens that are used at conventional doses in the second line, however in some cases they should receive treatment in an oncology center with a multidisciplinary team having access to treatment with high dose chemotherapy and to oncologist surgeons who are experts in this area.

ABSTRACT

Abstract Background Anorexia nervosa is a complex and highly variable disorder. Preventing patients from becoming resistant to treatments is fundamental since an important percentage develops a severe and enduring disorder; and because relapse is highly associated with psychiatric comorbidity, poor prognosis, and serious medical consequences due to malnutrition. Contemporary treatments for anorexia nervosa support the benefits of involving the family in treatment, and although the gold standard of family psychotherapy offers an excellent option for anorexia nervosa, that intervention is aimed at early stages, and therapeutic options for later stages of the disorder are reduced and not clearly established. Objective Expose the therapeutic effect of the protocol for severe and enduring cases of anorexia nervosa at relapse, used at the Clinic of Eating Behavior of the National Institute of Psychiatry, Ramón de la Fuente Muñiz, whose theoretical foundation is systemic therapy. Method To develop this case report, we carried out an in-depth review of the clinical records, and of the clinic attendance records of the case presented here. CARE clinical case report guidelines format were used. Results The case shows how a young woman, diagnosed with anorexia nervosa with clinical signs of severe and enduring anorexia nervosa (SE-AN), was able to achieve symptomatic remission after her parents, but not her, were administered the protocol for SE-AN. Discussion and conclusion Here we present an emblematic case showing the importance of getting the parents involved in the treatment of anorexia nervosa.


Resumen Antecedentes La anorexia nervosa es un trastorno complejo y muy variable. Evitar que los pacientes se vuelvan resistentes a los tratamientos es fundamental, pues un porcentaje importante desarrolla un trastorno grave y duradero; adicionalmente, la recaída está muy asociada con una alta comorbilidad psiquiátrica, un mal pronóstico y graves consecuencias médicas debido a la desnutrición. El tratamiento actual de la anorexia nervosa respalda los beneficios de involucrar a la familia en el tratamiento, y, aunque el estándar de oro en psicoterapia familiar ofrece una excelente opción para la anorexia nervosa, dicha intervención está orientada a etapas tempranas y las opciones para las etapas tardías del trastorno son reducidas, además de no estar claramente establecidas. Objetivo Exponer el efecto terapéutico del protocolo para casos graves y duraderos de anorexia nervosa en recaída, de la Clínica de Trastornos de la Conducta Alimentaria (CTA) del Instituto Nacional de Psiquiatría Ramón de la Fuente Muñiz, cuya base teórica es la terapia sistémica. Método Para integrar este caso, realizamos una revisión a fondo del expediente clínico y de los registros asistenciales del caso que aquí presentamos. Se utilizó el formato de reporte de caso de las guías CARE. Resultados El caso muestra cómo una joven, con signos clínicos de anorexia nervosa grave y duradera (AN-GD), pudo lograr remisión sintomatológica después de que sus padres, pero no ella, recibieran tratamiento con el protocolo para AN-GD. Discusión y conclusión Aquí presentamos un caso emblemático que muestra la importancia de involucrar a los padres en el tratamiento de la anorexia nervosa.

ABSTRACT

Abstract Objective The aim of the present study was to analyze relapse rates and patterns in patients with endometrial cancer with the aim of evaluating the effectiveness of current follow-up procedures in terms of patient survival, as well as the convenience of modifying the surveillance strategy. Methods Retrospective descriptive study including all patients diagnosed with endometrial cancer relapse at the Department of Gynecology and Obstetrics of the Complejo Hospitalario Insular-Materno Infantil de Canarias, between 2005 and 2014. Results Recurrence was observed in 81 patients (10.04% of the sample); 66.7% of them suffered relapse within 2 years and 80.2% within 3 years after the termination of the primary treatment; 41.9% showed distant metastases while the rest corresponded to local-regional (40.7%) or ganglionar (17.4%) relapse; 42% of these were symptomatic; 14 patients showed more than 1 site of relapse. Relapse was detected mainly through symptoms and physical examination findings (54.3%), followed by elevated serummarker levels (29.6%), computed tomography (CT) images (9.9%) and abnormal vaginal cytology findings (6.2%). No differences in global survival were found between patients with symptomatic or asymptomatic relapse. Conclusion Taking into account that the recurrence rate of endometrial cancer is low, that relapse occurs mainly within the first 3 years post-treatment and that symptom evaluation and physical examination are the most effective follow-up methods, we postulate that a modification of the current model of hospital follow-up should be considered.

ABSTRACT

Abstract INTRODUCTION: Leprosy recurrence is the reappearance of the disease after treatment with current schemes and discharged for cure and may have variable incubation periods. METHODS: This is a descriptive observational study of leprosy recurrence in Espírito Santo diagnosed between January 2018 and January 2020. RESULTS: One hundred and ninety-two cases were available, of which 30 were diagnosed with leprosy recurrence. CONCLUSIONS: In 25 cases, the incubation period was 5-15 years after the first treatment, favoring bacillary persistence. In the remaining 5 cases, the disease had recurred after 15 years, pointing to reinfection as none of them exhibited drug resistance.

ABSTRACT

Resumo O reaparecimento de variabilidade comportamental previamente extinta (i.e., recaída) foi investigado por meio dos modelos experimentais de renovação, restabelecimento e ressurgência. Na Fase de Treino (contexto A), ao serem expostos ao esquema múltiplo Lag 10 Acoplado, ratos apresentaram níveis similares de variabilidade nos dois componentes. Na Fase de Eliminação (contexto B), o esquema múltiplo Repetição Repetição promoveu a extinção da variabilidade. Na Fase de Teste (contexto A), com a suspensão da contingência de repetição e a liberação de reforços independentes, a variabilidade reapareceu no componente "Lag 10", anteriormente correlacionado com reforçamento da variação, mas não no componente "Acoplado". Esse resultado sugere que a variabilidade observada no teste de recaída corresponde à variabilidade operante, e não à variabilidade induzida pela extinção.


Abstract The reappearance of previously extinguished behavioral variability (i.e. relapse) was investigated with three experimental models: renewal, reinstatement and resurgence. In the Training Phase (context A), when exposed to the multiple Lag 10 Yoke schedule, rats showed similar levels of variability in both components. In the Elimination Phase (context B), the multiple Repetition schedule promoted the extinction of variability. In the Test Phase (context A), with the suspension of the repetition contingency and the delivery of response-independent reinforcers, variability reappeared in the "Lag 10" component, the one previously correlated with the reinforcement of variation, but not in the "Yoke" component. This result suggests that the variability observed in the relapse test corresponded to operant variability, and not to extinction-induced variability.

ABSTRACT

Objective:To investigate the effects of naltrexone hydrochloride combined with trazodone on preventing relapse in heroin addicts after detoxification.Methods:A total of 274 opioid heroin addicts who received treatment in Beijing Gaoxin Hospital between June 2016 and January 2019 were included in this study. After detoxification with methadone, all patients were randomly assigned to receive either naltrexone hydrochloride combined with trazodone (group 1, n = 60) or naltrexone hydrochloride alone (group 2, n = 60) for preventing relapse in heroin addicts. The effects on relapse prevention were determined in each group. Results:There were no significant differences in age distribution, sex composition, marital status, and drug use between groups 1 and 2 (all P > 0.05). After 6 months of treatment, the non-relapse rate was 86.7% (52/60) and 6.7% (4/60) in groups 1 and 2 respectively, in the case of unchanged personal life status. There was significant difference in non-relapse rate between groups 1 and 2 ( χ2 = 77.1, P < 0.001). Conclusion:Naltrexone hydrochloride combined with trazodone exhibits superior efficacy in preventing relapse in opioid heroin addicts after detoxification to naltrexone hydrochloride alone.

ABSTRACT

Objective:To investigate the value of minimal residual disease (MRD) in prediction of prognosis in acute lymphoblastic leukemia (ALL) patients with or above complete remission 2 (CR2) underwent.Methods:A retrospective analysis was performed on 201 ALL patients who received allogeneic stem cell transplantation (allo-SCT) and pretransplant disease status ≥CR2 in Peking University People′s Hospital from January 2009 to December 2018. MRD was measured by multi-parameter flow cytometry at 1 month before transplantation and 1 month, 2 months, 3 months, 4 months, 6 months, 9 months or 12 months after transplantation. To investigate the influence of dynamic changes of MRD before and after transplantation on prognosis.Results:201 ALL patients, including 126 males and 75 females, with a median age of 18 years. The 3-year cumulative incidence of relapse (CIR), non-relapse mortality (NRM), leukemia-free survival (LFS) and overall survival (OS) of all cases were 34%, 16%, 50%, and 56%, respectively. Positive pre-SCT MRD patients with higher 3-year CIR (47% vs 26%, P=0.003), lower 3-year LFS (40% vs 55%, P=0.047) and OS (42% vs 60%, P=0.065) than those with negative one. Subjects with positive post-MRD had higher 3-year CIR (73% vs 22%, P<0.001) and lower 3-year LFS (28% vs 56%, P=0.005) and OS (32% vs 60%, P=0.040) compared with those with negative one. Multivariate analysis showed that both pre-MRD and post-MRD were associated with higher CIR ( HR=1.823, P=0.018; HR=3.474, P<0.001), lower LFS ( HR=1.779, P=0.007; HR=2.185, P=0.001) and OS ( HR=1.609, P=0.034; HR=1.970, P=0.001). Negative pre-and post-SCT MRD group had lower 3-year CIR (17%, 42%, 82%; P<0.001) and higher 3-year LFS (61%, 44%, 18%; P<0.001) and OS (63%, 47%, 27%; P<0.001) compared with those unrisen post-SCT MRD group, and increased post-SCT MRD group. Multivariate analysis showed that pre-and post-SCT MRD dynamics were associated with CIR, LFS and OS ( P<0.01 for all) independently. The pre-and post-SCT MRD dynamics could better distinguish CIR (C=0.669) from that of pre-SCT MRD (C=0.587) and post-SCT MRD (C=0.629). Conclusion:Our data suggest that pre-SCT MRD, post-SCT MRD and the dynamic peri-SCT MRD could be used to predict transplant outcome of ALLpatients with or above CR2 who underwent allo-SCT.

ABSTRACT

Objective:To explore the strategies of reducing relapse after allogeneic hematopoietic stem cell transplantation (allo-HSCT) in patients with high-risk myelodysplastic syndrome (MDS) from the perspectives of optimizing the conditioning regimen and pre-transplant cytoreductive therapy.Methods:A total of 84 patients with high-risk MDS undergoing allo-HSCT between January 2013 and September 2019 were retrospectively analyzed. Based upon preparative regimens, they were divided into two groups of decitabine intensified BUCY2 ( n=49) and BUCY2 regimen ( n=35), based upon whether or not pre-treatment prior to allo-HSCT: cytoredutive treatment ( n=34) and none ( n=50). Two groups were compared with regards to hematopoietic reconstitution, graft-versus-host disease (GVHD), relapse rate, transplant-related mortality (TRM) and survival. Results:No significant inter-group differences existed in hematopoietic reconstitution or acute/chronic GVHD. The relapse rate was significantly lower in decitabine intensified group than that in BUCY2 group (18.7% vs 40.0%, P=0.025). Survival was significantly better in decitabine intensified group than that in BUCY2 group (3-year OS: 71.3% vs 51.2%, P=0.038; 3-year DFS: 65.3% vs 45.2%, P=0.033). Moreover, the incidence of recurrence was markedly lower in pre-transplant treatment group than that in non-treatment group (20.7% vs 38.9%, P=0.035). The inter-group incidence of TRM was not different. Three-year OS/DFS of treatment group were remarkably superior to those of non-treatment group (71.2% vs 50.8%, P=0.024; 64.7% vs 45.9%, P=0.044). Conclusions:As an optimal conditioning regimen for high-risk MDS, decitabine intensified BUCY2 regimen could better eliminate tumor burden, remarkably lower relapse rate and improve OS after allo-HSCT. In addition, pre-transplant treatment significantly reduces relapse and offers benefit for OS after allo-HSCT. Therefore intensified conditioning regimen and pre-transplant treatment may be promising strategies of reducing relapse and improving survival for high-risk MDS. However, it still needs further confirmation from prospective randomized controlled trials.

ABSTRACT

To analyze the prognostic factors of extramedullary relapse (EMR) after allogeneic hematopoietic stem cell transplantation (allo-HSCT) in acute lymphoblastic leukemia (ALL).The clinical data of 33 relapsed patients in 95 ALL patients receiving allo-HSCT were analyzed retrospectively. The median time of relapse was 5.7 (0.7-52.3) months. Extramedullary relapse was recorded in 10 cases (10.5%), bone marrow relapse in 15 cases (15.8%), and both extramedullary and marrow relapse were seen in 8 cases (8.4%). The median time of EMR was 7.4(0.7-52.3) months. The most commonly involved organ was central nervous system, followed by testis and bone. The 3-year OS rate in EMR patients was (33.3±11.1) %. Univariate analysis showed that disease state before transplantation ( P=0.026), extramedullary infiltration before transplantation ( P=0.005), conditioning regimens ( P=0.033) and acute graft-versus-host disease(aGVHD) ( P=0.013) were significantly correlated with EMR. Multivariate analysis suggested that extramedullary infiltration ( RR=5.067, 95 %CI1.542-16.645, P=0.007) and aGVHD( RR=3.585, 95 %CI1.245-10.320, P=0.018) were independent predictive factors of EMR in ALL patients after allo-HSCT.

ABSTRACT

Drug-associated reward memories are conducive to intense craving and often trigger relapse. Simvastatin has been shown to regulate lipids that are involved in memory formation but its influence on other cognitive processes is elusive. Here, we used a mass spectrometry-based lipidomic method to evaluate the impact of simvastatin on the mouse brain in a cocaine-induced reinstatement paradigm. We found that simvastatin blocked the reinstatement of cocaine-induced conditioned place preference (CPP) without affecting CPP acquisition. Specifically, only simvastatin administered during extinction prevented cocaine-primed reinstatement. Global lipidome analysis showed that the nucleus accumbens was the region with the greatest degree of change caused by simvastatin. The metabolism of fatty-acids, phospholipids, and triacylglycerol was profoundly affected. Simvastatin reversed most of the effects on phospholipids induced by cocaine. The correlation matrix showed that cocaine and simvastatin significantly reshaped the lipid metabolic pathways in specific brain regions. Furthermore, simvastatin almost reversed all changes in the fatty acyl profile and unsaturation caused by cocaine. In summary, pre-extinction treatment with simvastatin facilitates cocaine extinction and prevents cocaine relapse with brain lipidome remodeling.

ABSTRACT

Relapse is the main problem after allogeneic hematopoietic stem cell transplantation (allo-HSCT). The outcome of a second allo-HSCT (HSCT2) for relapse post-HSCT has shown promising results in some previous studies. However, little is known about the efficacy of HSCT2 in patients with relapsed/refractory acute leukemia (AL) post-chemotherapy plus modified donor lymphocyte infusion (post-Chemo + m-DLI) after the first allo-HSCT (HSCT1). Therefore, we retrospectively analyzed the efficacy of HSCT2 in 28 patients with relapsed/refractory AL post-Chemo + m-DLI in our center. With a median follow-up of 918 (457-1732) days, 26 patients (92.9%) achieved complete remission, and 2 patients exhibited persistent disease. The probabilities of overall survival (OS) and disease-free survival (DFS) 1 year after HSCT2 were 25.0% and 21.4%, respectively. The cumulative incidences of nonrelapse mortality on day 100 and at 1 year post-HSCT2 were 7.1% ± 4.9% and 25.0% ± 8.4%. The cumulative incidences of relapse were 50.0% ± 9.8% and 53.5% ± 9.9% at 1 and 2 years post-HSCT2, respectively. Risk stratification prior to HSCT1 and percentage of blasts before HSCT2 were independent risk factors for OS post-HSCT2, and relapse within 6 months post-HSCT1 was an independent risk factor for DFS and relapse post-HSCT2. Our findings suggest that HSCT2 could be a salvage option for patients with relapsed AL post-Chemo + m-DLI.
