A phase II study on the role of gemcitabine plus romidepsin (GEMRO regimen) in the treatment of relapsed/refractory peripheral T-cell lymphoma patients

There is no consensus regarding optimal treatment for peripheral T-cell lymphomas (PTCL), especially in relapsed or refractory cases, which have very poor prognosis and a dismal outcome, with 5-year overall survival of 30 %.



A multicenter prospective phase II trial was conducted to investigate the role of the combination of gemcitabine plus romidepsin (GEMRO regimen) in relapsed/refractory PTCL, looking for a potential synergistic effect of the two drugs. GEMRO regimen contemplates an induction with romidepsin plus gemcitabine for six 28-day cycles followed by maintenance with romidepsin for patients in at least partial remission. The primary endpoint was the overall response rate (ORR); secondary endpoints were survival, duration of response, and safety of the regimen.



The ORR was 30 % (6/20) with 15 % (3) complete response (CR) rate. Two-year overall survival was 50 % and progression-free survival 11.2 %. Grade ≥3 adverse events were represented by thrombocytopenia (60 %), neutropenia (50 %), and anemia (20 %). Two patients are still in CR with median response duration of 18 months. The majority of non-hematological toxicities were mild and transient. No treatment-related death occurred and no toxicity led to treatment interruption.



GEMRO combination regimen shows efficacy data similar to those of single-agent romidepsin with additional hematologic toxicities. Synergy observed in preclinical phase did not turn into ability to improve clinical outcomes.
Identification of a preoperative predictive factor for lymph node metastasis in uterine papillary serous carcinoma: long-term results from a single institution.

The purpose of this study was to identify preoperative clinicopathological predictive factors for lymph node (LN) metastasis in women diagnosed with uterine papillary serous carcinoma (UPSC).



Women diagnosed with UPSC in our institution from 1997 to 2012 were identified. All patients underwent hysterectomy and bilateral salpingo-oophorectomy plus pelvic and/or para-aortic lymphadenectomy. The predictive values of the risk factors for LN metastasis were analyzed using χ and multivariate logistic regression analyses.



A total of 94 patients met our study criteria. A CA-125 cutoff of 47.5 IU/mL on the receiver operating characteristic curve provided the best sensitivity and specificity (56.5% vs 90.1%, respectively) for LN metastasis prediction. The sensitivities and specificities of old age (≥60 years), body mass index of 25 kg/m or greater, deep myometrial invasion, tumor size greater than 2 cm, tumor size greater than 4 cm, preoperative CA-125 greater than 47.5 IU/mL, LN metastasis on imaging, and extrauterine spread on imaging for the presence of a positive LN were 39.1%, 34.8%, 30.4%, 34.8%, 21.7%, 56.5%, 43.5%, and 52.2%, and 52.1%, 45.1%, 78.9%, 57.7%, 83.1%, 90.1%, 93.0%, and 90.1%, respectively. Preoperative CA-125 (P < 0.001), LN metastasis on preoperative imaging (P < 0.001), and extrauterine spread on preoperative imaging (P = 0.009) were risk factors for LN metastasis on univariate analysis. Multivariate analysis revealed that preoperative CA-125 (P = 0.001) was the only independent risk factor for LN metastasis.



Preoperative CA-125 is a preoperative predictive factor for LN metastasis in UPSC.
CT Scan Screening for Lung Cancer: Risk Factors for Nodules and Malignancy in a High-Risk Urban Cohort

Low-dose computed tomography (CT) for lung cancer screening can reduce lung cancer mortality. The National Lung Screening Trial reported a 20% reduction in lung cancer mortality in high-risk smokers. However, CT scanning is extremely sensitive and detects non-calcified nodules (NCNs) in 24-50% of subjects, suggesting an unacceptably high false-positive rate. We hypothesized that by reviewing demographic, clinical and nodule characteristics, we could identify risk factors associated with the presence of nodules on screening CT, and with the probability that a NCN was malignant.



We performed a longitudinal lung cancer biomarker discovery trial (NYU LCBC) that included low-dose CT-screening of high-risk individuals over 50 years of age, with more than 20 pack-year smoking histories, living in an urban setting, and with a potential for asbestos exposure. We used case-control studies to identify risk factors associated with the presence of nodules (n=625) versus no nodules (n=557), and lung cancer patients (n=30) versus benign nodules (n=128).



The NYU LCBC followed 1182 study subjects prospectively over a 10-year period. We found 52% to have NCNs >4 mm on their baseline screen. Most of the nodules were stable, and 9.7% of solid and 26.2% of sub-solid nodules resolved. We diagnosed 30 lung cancers, 26 stage I. Three patients had synchronous primary lung cancers or multifocal disease. Thus, there were 33 lung cancers: 10 incident, and 23 prevalent. A sub-group of the prevalent group were stable for a prolonged period prior to diagnosis. These were all stage I at diagnosis and 12/13 were adenocarcinomas.



NCNs are common among CT-screened high-risk subjects and can often be managed conservatively. Risk factors for malignancy included increasing age, size and number of nodules, reduced FEV1 and FVC, and increased pack-years smoking. A sub-group of screen-detected cancers are slow-growing and may contribute to over-diagnosis and lead-time biases.
Outcome of surgically resected thymic carcinoma: a multicenter experience.

Thymic carcinoma (TC) is a rare and invasive mediastinal tumor, with poor prognosis. Most of the previous published papers are single-institution based, reporting small series of patient, sometimes including palliative resection. This study collected patients with TC treated in 5 high-volume Italian Thoracic Surgery Institutions.



A multicenter retrospective study of patients operated for TC between 2000 and 2011 was conducted. Exclusion criteria were: Neuroendocrine thymic neoplasms, debulking/palliative resection and tumor biopsy. Cause specific survival (CSS) was the primary endpoint.



Four hundred and seventy-eight patients underwent surgery for thymic malignancies: 40 of them (8.4%) had TC. Eleven (27.5%) received induction chemotherapy because of their radiological invasiveness. A complete resection (R0) was achieved in 36 (90%; 9/11 submitted to induction chemotherapy). Adjuvant radio/chemotherapy was offered to 37 patients, according to the type of surgical resection and tumor invasiveness. Three, 5 and 10-year survival rates were 79%, 75% and 58%. Recurrences developed in 10 patients. R0 resection (p<0.0003) and absence of tumor recurrences (p=0.03) resulted significant prognostic factors at univariate analysis. Independent CSS predictor was the achievement of a complete resection (p<0.05).



TC is a rare and invasive mediastinal tumor. A multimodal approach is indicated especially in TC invasive forms. The achievement of a complete surgical resection is fundamental to improve survival.
Dissociable Deficits in the Decision-Making Cognition of Chronic Amphetamine Abusers, Opiate Abusers, Patients with Focal Damage to Prefrontal Cortex, and Tryptophan-Depleted Normal Volunteers: Evidence for Monoaminergic Mechanisms

We used a novel computerized decision-making task to compare the decision-making behavior of chronic amphetamine abusers, chronic opiate abusers, and patients with focal lesions of orbital prefrontal cortex (PFC) or dorsolateral/medial PFC. We also assessed the effects of reducing central 5-hydroxytryptamine (5-HT) activity using a tryptophan-depleting amino acid drink in normal volunteers. Chronic amphetamine abusers showed sub-optimal decisions (correlated with years of abuse), and deliberated for significantly longer before making their choices. The opiate abusers exhibited only the second of these behavioral changes. Importantly, both sub-optimal choices and increased deliberation times were evident in the patients with damage to orbitofrontal PFC but not other sectors of PFC. Qualitatively, the performance of the subjects with lowered plasma tryptophan was similar to that associated with amphetamine abuse, consistent with recent reports of depleted 5-HT in the orbital regions of PFC of methamphetamine abusers. Overall, these data suggest that chronic amphetamine abusers show similar decision-making deficits to those seen after focal damage to orbitofrontal PFC. These deficits may reflect altered neuromodulation of the orbitofrontal PFC and interconnected limbic-striatal systems by both the ascending 5-HT and mesocortical dopamine (DA) projections.
Validation of the Portuguese version of the quality of life questionnaire of the European foundation for osteoporosis (QUALEFFO-41) in Brazilian women with postmenopausal osteoporosis with vertebral fracture

To validate the Portuguese version of the quality of life questionnaire of the European foundation for osteoporosis (QUALEFFO-41) in Brazilian women with osteoporotic vertebral fractures (VF). A questionnaire validation study of 86 postmenopausal women was conducted. Women were divided into two groups: 43 in a group with VF and 43 in a group without osteoporosis, age-matched (±3 years). The QUALEFFO-41 questionnaire was administered twice in 4 weeks and compared to a generic questionnaire SF-36. For analysis of the QUALEFFO-41, internal consistency, repeatability, and discriminant capacity between VF patients and control patients were assessed. The significance level adopted was 5 %. The mean age of the women was 66.1 ± 7.2 years for the group with VF and 64.9 ± 6.3 years for the control group (p = 0.4259). The QUALEFFO showed adequate internal consistency in all domains (Cronbach's α of 0.74 to 0.84) and good repeatability (ICC of domains = 0.67–0.90). Of the total questions, 92.6 % demonstrated satisfactory convergent validity, and 95 % of the questions showed good discriminant validity. The mean scores of both questionnaires were significantly higher in the group with VF. There was a good correlation among the QUALEFFO-41 domains and their corresponding SF-36 domains, except for social function. All QUALEFFO-41 domains were significantly predictive of VF on assessment of the ROC curve. The Portuguese version of the QUALEFFO-41 may be used in Brazilian women with osteoporotic VF because it shows good reliability, repeatability, and validity. It was also shown to impair quality of life (QOL) in women with VF and had good ability to discriminate QOL in women with osteoporotic VF.
Prospective trial of high-frequency oscillation in adults with acute respiratory distress syndrome.

To evaluate the safety and efficacy of high-frequency oscillatory ventilation (HFOV) in adult patients with the acute respiratory distress syndrome (ARDS) and oxygenation failure.



Prospective, clinical study.



Intensive care and burn units of two university teaching hospitals.



Twenty-four adults (10 females, 14 males, aged 48.5 +/- 15.2 yrs, Acute Physiology and Chronic Health Evaluation II score 21.5 +/- 6.9) with ARDS (lung injury score 3.4 +/- 0.6, Pao2/Fio2 98.8 +/- 39.0 mm Hg, and oxygenation index 32.5 +/- 19.6) who met one of the following criteria: Pao2 < or =65 mm Hg with Fio2 > or =0.6, or plateau pressure > or =35 cm H2O.



HFOV was initiated in patients with ARDS after varying periods of conventional ventilation (CV). Mean airway pressure (Paw) was initially set 5 cm H2O greater than Paw during CV, and was subsequently titrated to maintain oxygen saturation between 88% and 93% and Fio2 < or =0.60.



Fio2, Paw, pressure amplitude of oscillation, frequency, blood pressure, heart rate, and arterial blood gases were monitored during the transition from CV to HFOV, and every 8 hrs thereafter for 72 hrs. In 16 patients who had pulmonary artery catheters in place, cardiac hemodynamics were recorded at the same time intervals. Throughout the HFOV trial, Paw was significantly higher than that applied during CV. Within 8 hrs of HFOV application, and for the duration of the trial, Fio2 and Paco2 were lower, and Pao2/Fio2 was higher than baseline values during CV. Significant changes in hemodynamic variables following HFOV initiation included an increase in pulmonary artery occlusion pressure (at 8 and 40 hrs) and central venous pressure (at 16 and 40 hrs), and a reduction in cardiac output throughout the course of the study. There were no significant changes in systemic or pulmonary pressure associated with initiation and maintenance of HFOV. Complications occurring during HFOV included pneumothorax in two patients and desiccation of secretions in one patient. Survival at 30 days was 33%, with survivors having been mechanically ventilated for fewer days before institution of HFOV compared with nonsurvivors (1.6 +/- 1.2 vs. 7.8 +/- 5.8 days; p =.001).



These findings suggest that HFOV has beneficial effects on oxygenation and ventilation, and may be a safe and effective rescue therapy for patients with severe oxygenation failure. In addition, early institution of HFOV may be advantageous.
A randomized trial of two types of adjuvant chemotherapy in radiotherapy-treated patients with clinical stages I and II high-grade non-Hodgkin's lymphoma

This paper reports the 8-year results of comparing the use of two types of adjuvant chemotherapy following involved field radiotherapy for clinical stages I and II high-grade non-Hodgkin's lymphoma. Twenty-four patients received 6 weeks of VAP plus 2 years of oral maintenance chemotherapy, and 30 had six cycles of CMOPP. Four patients were not in complete remission at completion of i. v. chemotherapy (CR rate 91%). Ten patients (18.5%) have relapsed (VAP/M=5; CMOPP=5), with only two of these remaining alive, both of them being disease free. There have been three deaths from intercurrent causes, one from malignant melanoma and the other two from myocardial infarction. The relapse-free survivals at 2, 5 and 8 years were 80%, 76% & 76% respectively. The overall survivals at the same time points were 86%, 72% & 68%. There were no significant differences in either relapse-free or overall survival for either of the two treatment groups. The shorter period of weekly intravenous chemotherapy (VAP/M) was better tolerated than 36 weeks of CMOPP, and the former appears to produce equivalent results.
Culturally appropriate education intervention on biospecimen research participation among Chinese Americans.

Chinese Americans are at increased risk for hepatitis B virus (HBV) infection. To reduce or eliminate disparities in HBV-related infection rates, participation in scientific investigations of HBV risk and treatment, including biospecimen sampling, is important. However, Asian Americans have low rates of participation in biospecimen research, and little is known about how educational interventions affect knowledge and participation in HBV-related biospecimen research.



Eight Chinese community-based organizations participated in a quasi-experimental, two-group design with education assessments at pre- and postworkshop and a 3-month follow-up. Four sites were randomly assigned to receive the intervention (n = 175) and four sites to receive general health education (control; n = 240).



Participant knowledge about biospecimen research increased from pre- to posteducation in the intervention but not in the control condition. Of intervention participants, 83.4% (146/175) donated one tube of blood for future HBV biospecimen research, and 50.9% (89/175) donated another tube of blood for HBV testing. In contrast, only 1.1% of participants in the control condition reported donating a blood sample at follow-up assessment.



The intervention program significantly increased knowledge of and participation in HBV biospecimen research among Chinese Americans. Community-based participatory research (CBPR) methods featured active support by community leaders, a culturally specific curriculum, and convenient, immediate access to blood sampling, which resulted in high donation rates.



HBV-related morbidity and mortality is an urgent problem faced by Chinese Americans. CBPR provides a model for engaging communities in early detection, vaccination, and treatment that can reduce this health threat.
Understanding engagement with tangible user interfaces

This paper examines the issues surrounding the successful design and development of tangible technology for optimal engagement in playful activities. At present there is very little data on how, and in what contexts, tangible interactions with technology promote lasting engagement and immersion. The framework at the core of this paper has been designed to guide the effective design of tangible technology for immersive interaction. The paper investigates the relationship between tangible user interfaces (TUI) characteristics of representation and control, and immersive flow experiences produced through balancing skill and challenge in user interaction.
The Difference-Bit Cache

The difference-bit cache is a two-way set-associative cache with an access time that is smaller than that of a conventional one and close or equal to that of a direct-mapped cache. This is achieved by noticing that the two tags for a set have to differ at least by one bit and by using this bit to select the way. In contrast with previous approaches that predict the way and have two types of hits (primary of one cycle and secondary of two to four cycles), all hits of the difference-bit cache are of one cycle. The evaluation of the access time of our cache organization has been performed using a recently proposed on-chip cache access model.
Gene therapy study of cytokine-transfected xenogeneic cells (Vero-interleukin-2) in patients with metastatic solid tumors

On the basis of compelling preclinical data in cats and dogs, we initiated a clinical gene therapy study in nine patients with advanced solid tumors using xenogeneic fibroblasts secreting human interleukin (IL)-2 (Vero-IL-2 cells). Cohorts of three successive patients with tumors accessible to computed tomography- or ultrasound-guided injection were treated repeatedly with 5 × 105, 5 × 106, or 5 × 107 Vero-IL-2 cells. The endpoints of the study were feasibility, toxicity, and the clinical and biological effects of this novel approach to immunotherapy of cancer. Histopathological, immunological, and molecular analyses were performed on biopsy specimens of tumors and blood samples before, during, and after treatment. Treatment was well tolerated, and toxicity consisted of transient fever in one patient and short-lived, mild itching and erythema in two others. One patient with soft-tissue sarcoma showed a reduction of >90% and >50% of the volume of two distant, noninjected metastases, lasting for 29+ and 26 months, respectively. Four other patients showed stabilization of their disease for 3–9 months; of these patients, one with melanoma developed marked vitiligo. We conclude that repeated injections of ≤5 × 107 Vero-IL-2 cells are feasible and safe in heavily pretreated patients with advanced solid tumors. An additional evaluation of an intratumoral application of Vero-IL-2 seems warranted.
Clinical Practice Experiences in Diagnosis and Treatment of Traumatic Brain Injury in Children: A Survey among Clinicians at 9 Large Hospitals in China

Proper diagnosis and treatment of traumatic brain injury (TBI) in children is becoming an increasingly problematic issue in China. This study investigated Chinese clinicians to provide information about their knowledge and experiences in diagnosis and treatment of pediatric TBI. We conducted a questionnaire survey among clinicians in the emergency departments and neurosurgery departments at 9 major hospitals in China. The questionnaire included demographic information, and knowledge and experiences regarding the diagnosis and treatment of pediatric TBI. A total of 235 clinicians completed questionnaires. 43.8% of the surveyed clinicians reported children with only scalp hematoma without any other signs and symptoms of concussion as TBI cases. Most clinicians (85.1%) reported no existing uniform diagnostic criteria for children with TBI in China. The majority of clinicians (91.9%) reported that CT scans were performed in all patients with suspected head injury as a routine procedure in their hospitals. Only 20.9% of clinicians believed that radiation from CT scanning may increase cancer risk in children. About 33.6% of the clinicians reported that they ordered CT scans to investigate suspected head injury due to the poor doctor-patient relationship in China, and to protect themselves against any medical lawsuits in the future. About 80% of the clinicians reported that there are no existing pediatric TBI treatment guidelines in China. Instead a senior doctor's advice is the most reported guidelines regarding treating pediatric TBI (66.0%). All of the surveyed clinicians reported that the lack of diagnosis and/or treatment standard is the biggest problem in effectively diagnosing and treating pediatric TBI in China. Developing guidelines for the diagnosis and treatment of children with TBI is a high priority in China. The extremely high usage of CT for pediatric TBI in China suggests that it is important to establish evidence-based clinical decision rules to help Chinese clinicians make diagnostic and therapeutic decisions during their practice in order to identify children unlikely to have a clinically-important TBI who can be safely discharged without a CT scan.
A multicentre case control study on complicated coeliac disease: two different patterns of natural history, two different prognoses

Coeliac disease is a common enteropathy characterized by an increased mortality mainly due to its complications. The natural history of complicated coeliac disease is characterised by two different types of course: patients with a new diagnosis of coeliac disease that do not improve despite a strict gluten-free diet (type A cases) and previously diagnosed coeliac patients that initially improved on a gluten-free diet but then relapsed despite a strict diet (type B cases). Our aim was to study the prognosis and survival of A and B cases.



Clinical and laboratory data from coeliac patients who later developed complications (A and B cases) and sex- and age-matched coeliac patients who normally responded to a gluten-free diet (controls) were collected among 11 Italian centres.



87 cases and 136 controls were enrolled. Complications tended to occur rapidly after the diagnosis of coeliac disease and cumulative survival dropped in the first months after diagnosis of complicated coeliac disease. Thirty-seven cases died (30/59 in group A, 7/28 in group B). Type B cases presented an increased survival rate compared to A cases.



Complicated coeliac disease is an extremely serious condition with a high mortality and a short survival. Survival depends on the type of natural history.
