RESUMO

Allogeneic hematopoietic stem cell transplantation (allo-HSCT) is still a potentially curative option for B-cell Non-Hodgkin Lymphoma (B-NHL) in the modern immunotherapy era. The objective of this study was to analyze long-term outcomes of patients with B-NHL who received allo-HSCT. We analyzed overall survival (OS), progression-free survival (PFS) and graft versus host disease (GVHD) relapse-free survival (GRFS) in 53 patients undergoing allo-HSCT from two institutions. The median follow-up of the study was 72 months (range 29-115 months). The median number of lines of therapy before allo-HSCT was 3 (range 1-6) and twenty-eight patients (53%) had received a previous autologous transplant. The 3-year PFS, OS and GRFS were 55%, 63%, and 55%, respectively. One-year non-relapse mortality was 26%. Karnofsky Performance Scale < 90 was associated with worse OS in multivariable analysis. A non-comparative analysis of a cohort of 44 patients with similar characteristics who received chimeric antigen receptor T-cell therapy was done, showing a 1-year PFS and OS were 60% and 66%, respectively. Our data shows that allo-HSCT is still a useful option for treating selected patients with R/R B-NHL. Our retrospective analysis and review of the literature demonstrate that allo-HSCT can provide durable remissions in a subset of patients with R/R B-NHL.

RESUMO

Objetivo: Presentar una serie de casos de pacientes con fracturas cervicales de tipo "masa lateral flotante" con énfasis en describir el rol de la lesión discal en la potencial inestabilidad segmentaria. Materiales y métodos: Se realizó un estudio descriptivo y retrospectivo de una serie de pacientes con fracturas facetarias de tipo "masa lateral flotante", aisladas, diagnosticadas entre el 1 de enero de 2016 y el 1 de enero de 2022. Se incluyeron pacientes con lesiones de tipo "masa lateral flotante" según la clasificación AO, diagnosticadas por tomografía computarizada y, al menos, 6 meses de seguimiento. Se excluyó a aquellos con fracturas patológicas, lesiones por fragilidad ósea y registros incompletos. Resultados: Se analizó a 16 pacientes (media de la edad 42.86; DE 12,396), con predominio del sexo masculino (81,25%). El 68,75% tenía una lesión del disco intervertebral en el segmento fracturado y el 18,75%, anterolistesis. A 11 pacientes se les propuso un tratamiento conservador durante 12 semanas. La fractura consolidó en el 45,4% y 6 (54,6%) evolucionaron con traslación. El fracaso del tratamiento conservador se asoció con lesión del disco intervertebral. Once pacientes fueron operados, en su mayoría, con artrodesis cervical anterior monosegmentaria. Conclusiones: En esta serie de casos, la presencia de una lesión asociada del disco intervertebral fue más frecuente cuando el tratamiento conservador fracasó y cuando se decidió una artrodesis como tratamiento inicial. La mayoría de las cirugías se realizaron por vía anterior con discectomía y artrodesis cervical anterior en un único nivel, y se lograron buenos resultados. Nivel de Evidencia: IV


Introduction: We report a series of patients with "floating lateral mass" cervical fractures, focusing on the role of disc injury in potential segmental instability. materials and methods: We conducted a descriptive and retrospective study on a case series of isolated floating lateral mass facet fractures diagnosed between January 1, 2016 and January 1, 2022. Patients with floating lateral mass lesions according to the AO classification, diagnosed by computed tomography, and at least 6 months of follow-up were included. Patients with pathological fractures, bone fragility injuries and incomplete records were excluded. Results: We included 16 cases, the average age was 42.86 (SD 12.396), and the majority were male (n=13; 81.25%). 68.75% (n=11) had intervertebral disc injury in the fractured segment, while 18.75% (n=3) had anterolisthesis. Conservative treatment was proposed for 12 weeks in 11 patients (68.75%), of whom 5 (45.4%) achieved fracture healing and 6 (54.6%) progressed to translation. Cases where conservative treatment failed were associated with intervertebral disc injury. Eleven patients were treated surgically, mostly with monosegmental anterior cervical arthrodesis. Conclusions: We report a series of cases in which the existence of an associated intervertebral disc injury was more frequent in patients with failed conservative treatment and in those initially treated with arthrodesis. Most of the surgical cases were treated using an anterior approach with discectomy and anterior cervical arthrodesis at a single level, with favorable outcomes. Level of Evidence: IV

RESUMO

Less-intensive induction therapies are increasingly used in older patients with acute myeloid leukemia (AML). Using an AML composite model (AML-CM) assigning higher scores to older age, increased comorbidity burdens, and adverse cytogenetic risks, we defined 3 distinct prognostic groups and compared outcomes after less-intensive vs intensive induction therapies in a multicenter retrospective cohort (n = 1292) treated at 6 institutions from 2008 to 2012 and a prospective cohort (n = 695) treated at 13 institutions from 2013 to 2017. Prospective study included impacts of Karnofsky performance status (KPS), quality of life (QOL), and physician perception of cure. In the retrospective cohort, recipients of less-intensive therapies were older and had more comorbidities, more adverse cytogenetics, and worse KPS. Less-intensive therapies were associated with higher risks of mortality in AML-CM scores of 4 to 6, 7 to 9, and ≥10. Results were independent of allogeneic transplantation and similar in those age 70 to 79 years. In the prospective cohort, the 2 groups were similar in baseline QOL, geriatric assessment, and patient outcome preferences. Higher mortality risks were seen after less-intensive therapies. However, in models adjusted for age, physician-assigned KPS, and chance of cure, mortality risks and QOL were similar. Less-intensive therapy recipients had shorter length of hospitalization (LOH). Our study questions the survival and QOL benefits (except LOH) of less-intensive therapies in patients with AML, including those age 70 to 79 years or with high comorbidity burdens. A randomized trial in older/medically infirm patients is required to better assess the value of less-intensive and intensive therapies or their combination. This trial was registered at www.clinicaltrials.gov as #NCT01929408.

RESUMO

BACKGROUND: We aimed to assess the effects of safinamide on depression, motor symptoms, and the serotonin syndrome related to its co-administration with antidepressants in patients with Parkinson's disease (PD). METHODS: We retrospectively analyzed the data of patients at 1 and 3 months of follow-up compared to baseline. RESULTS: n = 82 (safinamide 50 mg = 22, 100 mg = 60, with antidepressants = 44). First, we found improvement in depression (Hamilton Depression Rating Scale: -6 ± 5.10 at 1 month and -7.27 ± 5.10 at 3 months, p < 0.0001; Patient Global Impression of Improvement Scale: 60.3% and 69.5% of patients at 1 and 3 months reported some improvement). Second, safinamide improved the daily life activities and motor symptoms/motor complications (Unified Parkinson's Disease Rating Scale (UPDRS-II): -2.51 ± 6.30 and -2.47 ± 6.11 at 1 and 3 months, p < 0.0001; III: -3.58 ± 8.68 and -4.03 ± 8.95 at 1 and 3 months, p < 0.0001; IV: -0.61 ± 2.61 and -0.8 ± 2.53 at 1 and 3 months, p < 0.0001). Third, 7.31% and 8.53% of patients developed non-severe adverse events related to safinamide at 1 and 3 months. Serotonin syndrome was not observed in the patients treated with antidepressants; some isolated serotonin syndrome symptoms were reported. CONCLUSIONS: Safinamide could be useful for treating depression in PD; it was effective for motor symptoms and motor complications and safe even when co-administered with antidepressants.

RESUMO

The occurrence of aflatoxin M1 (AFM1) in infant formulae commercialized in the metropolitan area of Monterrey (Nuevo León, Mexico) was determined by using immunoaffinity column clean-up followed by HPLC determination with fluorimetric detection. For this, 55 infant formula powders were classified in two groups, starter (49 samples) and follow-on (6 samples) formulae. Eleven of the evaluated samples (20%) presented values above the permissible limit set by the European Union for infant formulae (25 ng/L), ranging from 40 to 450 ng/L. The estimated daily intake (EDI) for AFM1 was determined employing the average body weight (bw) of the groups of age in the ranges of 0-6 and 6-12 months, and 1-2 years. The results evidenced high intake values, ranging from 1.56 to 14 ng/kg bw/day, depending on the group. Finally, with the EDI value, the carcinogenic risk index was determined, presenting a high risk for all the evaluated groups. Based on these results, it is a necessary extra effort by the regulatory agencies to reduce the AFM1 presence in infant formulae consumed in Mexico.

RESUMO

Importance: To our knowledge, this multicenter analysis is the first to test and validate (1) the prognostic impact of comorbidities on 1-year mortality after initial therapy of acute myeloid leukemia (AML) and (2) a novel, risk-stratifying composite model incorporating comorbidities, age, and cytogenetic and molecular risks. Objective: To accurately estimate risks of mortality by developing and validating a composite model that combines the most significant patient-specific and AML-specific features. Design, Setting, and Participants: This is a retrospective cohort study. A series of comorbidities, including those already incorporated into the hematopoietic cell transplantation­comorbidity index (HCT-CI), were evaluated. Patients were randomly divided into a training set (n = 733) and a validation set (n = 367). In the training set, covariates associated with 1-year overall mortality at a significance level of P < .10 constructed a multivariate Cox proportional hazards model in which the impact of each covariate was adjusted for that of all others. Then, the adjusted hazard ratios were used as weights. Performances of models were compared using C statistics for continuous outcomes and area under the curve (AUC) for binary outcomes. Exposures: Initial therapy for AML. Main Outcomes and Measures: Death within 1 year after initial therapy for AML. Results: A total of 1100 patients, ages 20 to 89 years, were treated for AML between January 1, 2008, and December 31, 2012, at 5 academic institutions specialized in treating AML; 605 (55%) were male, and 495 (45%) were female. In the validation set, the original HCT-CI had better C statistic and AUC estimates compared with the AML comorbidity index for prediction of 1-year mortality. Augmenting the original HCT-CI with 3 independently significant comorbidities, hypoalbuminemia, thrombocytopenia, and high lactate dehydrogenase level, yielded a better C statistic of 0.66 and AUC of 0.69 for 1-year mortality. A composite model comprising augmented HCT-CI, age, and cytogenetic/molecular risks had even better predictive estimates of 0.72 and 0.76, respectively. Conclusions and Relevance: In this cohort study, comorbidities influenced 1-year survival of patients with AML, and comorbidities are best captured by an augmented HCT-CI. The augmented HCT-CI, age, and cytogenetic/molecular risks could be combined into an AML composite model that could guide treatment decision-making and trial design in AML. Studying physical, cognitive, and social health might further clarify the prognostic role of aging. Targeting comorbidities with interventions alongside specific AML therapy might improve survival.

RESUMO

OBJECTIVE: To evaluate the psychometric properties of the Spanish version of the short-form of the Children Perceived Oral Health Questionnaire aimed at assessing child's oral health-related quality of life of children aged 11-14 years (CPQ11-14 ). A secondary objective was to explore its screening qualities for evaluating oral health needs and immediate referral for treatment. METHODS: This cross-sectional study was conducted during August-December of 2011 in Monterrey, Mexico (n = 303 schoolchildren). The CPQ11-14 consisted of 16 items and 2 key questions. Dental caries was diagnosed by visual-tactile exam, and malocclusion by WHO index. We estimated Cronbach's alpha and Spearman's correlations and compared rank scores with the Mann-Whitney test. As we did not have a preestablished cutoff point score, we identified one with the best combination of sensitivity/specificity values using receiver operating characteristic curves. RESULTS: Internal consistency was 0.85. Correlation was 0.40 (P < 0.001) between CPQ11-14 scores and self-perceived oral health rating and 0.51 (P < 0.001) between CPQ11-14 score and general well-being rating (concurrent validity). The mean score was 11.6 ± 8.6 for children in need of oral care and 8.1 ± 7.2 for those not in need of oral care (P < 0.01; discriminating validity). Sensitivity was 79.4% and specificity 48.7%; the positive and negative predictive values were 81.6% and 45.2%, respectively. CONCLUSIONS: The Spanish version short-form CPQ11-14 registered acceptable psychometric properties. We were able to identify a cutoff point score with acceptable sensitivity and positive predictive value but still needs future validation before generalizing its use.

RESUMO

Stereotactic bilateral electrode implantation in the medial portion of the posterior hypothalamus was performed on a 22-year-old male with drug-resistant aggressiveness. To localize the targets during implantation, microrecording was performed, and the clinical and electroencephalographic responses to intraoperative stimulation were monitored. The patient had an improved response to low-frequency stimulation that was sustained 18 months later at a follow-up examination.

RESUMO

We analyzed factors associated with skin erosion in 55 patients treated with deep brain stimulation (Kinetra or Soletra) for Parkinson's (PD) or other diseases. Nine of 55 patients developed erosion, all of whom were PD patients who had been fitted with a Kinetra device (r = 0.9292; p < 0.005). Erosions may be due to an increased pressure over the skin resulting from the larger size and weight of the Kinetra device. Alternatively, erosions in patients with the Kinetra device and bilateral leads may arise from the larger size of the 2 extension wires into the same subcutaneous tunnel and from the larger size of the 2 close parieto-occipital connections on the same cranial side. In PD patients, erosions were not related to age, immobility or PD severity. Specific studies examining the role of the skin of PD patients in erosion development and the use of smaller stimulation systems may help minimize the erosion rate.
