Using the Eco-Map and Ecosystems Perspective to Guide Skilled Nursing Facility Discharge Planning.

Growing numbers of seniors across the United States require skilled nursing facility care after an inpatient hospital stay. Previous studies indicate that roughly 20 percent of all hospitalized Medicare beneficiaries are admitted to a skilled nursing facility following a qualifying hospital stay. Social workers address psychosocial problems, social support, networks, and healthcare needs during transitions in care, particularly discharge planning. Ecosystems perspective and the eco-map as a discharge planning tool is presented. Social workers can use these tools to examine the patient with respect to their transactional relationships with systems. This will further will facilitate provision of wrap-around services upon discharge.

Therapeutic efficiency of platelet gel for the treatment of oral ulcers related to chronic graft versus host disease after allogeneic haematopoietic stem cell transplantation.

BACKGROUND: Platelet (PLT) gel has been successfully used in tissue regeneration of diabetic and surgical wounds through the releasing of growth factors such as basic fibroblast and PLT-derived growth factors. Based on this background, our previous clinical trial have assessed the feasibility and efficacy of PLT gel for the treatment of muco-cutaneous lesions related to graft versus host disease (GvHD) after allogeneic haematopoietic stem cell transplantion (HSCT). The promising results reported in a small series of 6 patients, of whom 1 with oral ulcers, represent the rationale of the present study. MATERIALS AND METHODS: The aim of this study was to verify the efficacy and safety of PLT gel for treating oral ulcers due to chronic GvHD. Allogeneic hemocomponents were used to obtain PLT gel with an automated system for the on-site preparation and application of patient (autologous) or healthy blood donor (allogeneic)-derived fibrin sealant or PLT-rich fibrin (Vivostat system, Vivostat A/S). Ten patients with multiple oral lesions related to chronic GvHD underwent allogeneic PLT gel as local therapy alone or in combination with systemic therapy in half of the cases. RESULTS: After the second PLT gel application, all patients resumed the feeding and a significant improvement of the oral pain was observed. After a median of five PLT gel applications (range, 2-15), 7 out of 10 patients showed a complete response. No side effects were documented. CONCLUSION: These data confirm that the PLT gel may be used as a safe and effective tool, alone or in combination with systemic therapy, for the treatment of mucosal lesions of mouth related to cGvHD.

Serum thymosin α 1 levels in patients with chronic inflammatory autoimmune diseases.

Thymosin alpha 1 (Tα1) is a powerful modulator of immunity and inflammation. Despite years of studies, there are a few reports evaluating serum Tα1 in health and disease. We studied a cohort of healthy individuals in comparison with patients affected by chronic inflammatory autoimmune diseases. Sera from 120 blood donors (healthy controls, HC), 120 patients with psoriatic arthritis (PsA), 40 with rheumatoid arthritis (RA) and 40 with systemic lupus erythematosus (SLE), attending the Transfusion Medicine or the Rheumatology Clinic at the Policlinico Tor Vergata, Rome, Italy, were tested for Tα1 content by means of a commercial enzyme-linked immunosorbent assay (ELISA) kit. Data were analysed in relation to demographic and clinical characteristics of patients and controls. A gender difference was found in the HC group, where females had lower serum Tα1 levels than males (P < 0·0001). Patients had lower serum Tα1 levels than HC (P < 0·0001), the lowest were observed in PsA group (P < 0·0001 versus all the other groups). Among all patients, those who at the time of blood collection were taking disease-modifying anti-rheumatic drugs (DMARD) plus steroids had significantly higher Tα1 levels than those taking DMARD alone (P = 0·044) or no treatment (P < 0·0001), but not of those taking steroids alone (P = 0·280). However, whichever type of treatment was taken by the patients, serum Tα1 was still significantly lower than in HC and there was no treatment-related difference in PsA group. Further prospective studies are necessary to confirm and deepen these observations. They might improve our understanding on the regulatory role of Tα1 in health and disease and increase our knowledge of the pathogenesis of chronic inflammatory autoimmune diseases.

Higher CD3(+) and CD34(+) cell doses in the graft increase the incidence of acute GVHD in children receiving BMT for thalassemia.

We evaluated the incidence of GVHD, risk factors and the impact of graft composition on acute GVHD (aGVHD) in 92 children who underwent BMT for thalassemia following busulfan/cyclophosphamide (BUCY)-based conditioning regimens and GVHD prophylaxis with CSA/short-MTX and methylprednisolone. The incidence of grade 2-4 and 3-4 aGVHD was 35% (95% confidence interval (CI) 25-44) and 9% (95% CI 4-16), respectively. We found that CD3(+) and CD34(+) cell doses above the median were associated with high incidence of grade 2-4 aGVHD (49 vs 20%, P=0.005 and 46 vs 23%, P=0.021, respectively). In multivariate analysis, high CD3(+) (hazard ratio (HR) 4.6; 95% CI 1.4-14.7; P=0.010) and CD34(+) (HR 4.3; 95% CI 1.4-12.7; P=0.011) cell doses were associated with grade 2-4 aGVHD. We further examined the effect of CD3(+) and CD34(+) cell doses on aGVHD using quartile cutoff points and found a minimum threshold for CD3(+) (38 × 10(6)/kg) and CD34(+) (4 × 10(6)/kg) cells above which the incidence of grade 2-4 aGVHD is significantly increased. This study shows for the first time a positive correlation between the number of CD3(+) and CD34(+) cells and aGVHD in children receiving sibling BMT, and indicates that using tailored and more intensive post transplant immunosuppression may permit to better control aGVHD.

Treatment of diabetic ulcers, using autologous platelet and fibrinic gel. Experience the FIBRINET® device.

There is evidence that platelets may be used locally as a source of growth factors that play a fundamental role in wound healing. From October 2008 to September 2009, at Tor Vergata Rome University Hospital, seven patients were enrolled in the study. All of these patients had ulcers with a extension over 3.5 cm(2). Four patients achieved a total recovery of the ulcers, while three experienced a reduction of the diameter of the ulcers. Our data are preliminary, but it is possible to suggest that recovery of the ulcers using the FIBRINET® system is related to platelet activation in the specific ulcer area.

Accurate prediction of autologous stem cell apheresis yields using a double variable-dependent method assures systematic efficiency control of continuous flow collection procedures.

BACKGROUND AND OBJECTIVES: Stem cell collection is a standard procedure for the procurement of autologous grafts to rescue myelosuppression induced by high-dose treatments. Accurate prediction of collection yields may contribute to optimize planning and quality control of collection. MATERIALS AND METHODS: Data of 313 autologous haematopoietic stem cell (AHSC) evaluable collections performed in 208 patients with haematologic and non-haematologic neoplasms from seven centres were prospectively analysed to test the accuracy of yield predictions generated by a formula that required the input of peripheral blood (PB) CD34+ cell precount and desired PB volume to be processed. Data were matched in a standard linear regression, in a zero-point regression analysis and tested for prediction accuracy. Further 165 AHSC collections were analysed on a single-centre basis, using yield predictions as reference standards. RESULTS: Analysis showed high levels of correlation between measured collection yields (my) and predictions (py) (R = 0.85; P = 0.000000) as well as high degree of prediction accuracy (my vs. py at paired t-test: P = 0.114781; median my/py ratio = 1.23). Analysis of additional 165 AHSC collections on a single-centre basis showed that the analysed centres had 70% or more measured yields comprising the 0.6-1.8 interval of the my/py ratio. The observance of the 'efficiency' my/py interval assured collection quality control in these centres confirming the reliability of the method. CONCLUSIONS: This prediction method generates accurate and immediate yield predictions allowing collection planning and rapid efficiency control. As a consequence of our study, four centres out of seven use the described method to plan both leukapheresis number and single-procedure blood processing volume while the remaining three centres plan leukapheresis number on the basis of our predictions, maintaining a fixed single-procedure 200 ml/kg blood volume processing, according to their centre AHSC collection policy.

Femoral catheters: safety and efficacy in peripheral blood stem cell collection.

Central venous access is necessary in patients candidate for peripheral blood stem cell (PBSC) collection. We report our experience with a dual lumen femoral catheter (Gamcath, 11 french), initially designed for hemodialysis. We studied 147 patients and performed 488 collections after mobilization with either G-CSF alone or chemotherapy + G-CSF, when the white blood cell count exceeded 1 x 10(9)/L, or when a measurable population of CD34+ cells (20/microL) was detected in peripheral blood. All patients received systemic anticoagulation with a low weight heparin and ultrasound examination was performed after the removal of the catheter. Seven patients developed thrombosis (4.7%), ten experienced hematomas at the site of catheter placement (6.8%) despite prophylactic platelet transfusions, while only one patient (0.6%) had a catheter-related infection. In conclusion, the short-term use of large bore femoral catheters in setting up PBSC collection seems to be associated with minimal risk of infection and low thrombotic incidence.

Enumeration of CD34+ hematopoietic progenitor cells for clinical transplantation: comparison of three different methods.

Three different methods for determination of CD34+ cells in G-CSF-mobilized peripheral blood were compared. The methods were: the Milan/Mulhouse protocol, the ISHAGE guidelines for CD34+ cells enumeration and our own protocol. The procedure we have adopted is essentially a Milan/Mulhouse protocol-derived methodology combined with a multiparametric approach using the PAINT-A-GATE software analysis program. The samples were collected from 70 patients affected by acute leukemia, non-Hodgkin's lymphoma, Hodgkin's lymphoma, myeloma and breast cancer who were scheduled to receive autologous PBSC transplantation. PBSC collection was performed following mobilization with subcutaneous G-CSF at 5-10 microg/kg/day. A minimum target of 2 x 10(6)/kg CD34+ cells was considered an acceptable harvest to ensure a safe transplant. On average, three aphereses per patient were performed and a total of 204 apheresis samples were analyzed. Regression analysis of the percentage and absolute number of CD34+ cells, as calculated with each method, achieved an excellent correlation in spite of methodological differences. In fact, both CD34+dim and CD34+CD45- events were included in our gating strategy. In the setting of a triple staining associating CD34, CD38 and CD45, we identified a variable fraction of CD34+CD38+CD45- cells which would be otherwise undetected due to its CD45 negativity. To this end, we used a new technology referred to as laser-scanning cytometry (LSC) which allowed the isolation and morphological identification of CD34+CD45- cells. By comparing CD34+CD45+ and CD34+CD45- cells, we found that they share a common morphology, thus confirming the hypothesis that the latter are to be considered for CD34+ cell calculation. The median number of CD34+ cells/kg, as calculated by the three methods, was: 4.79 x 10(6)/kg (range 1-570) for the Milan/Mulhouse protocol, 3.9 x 10(6)/kg (range 0.8-498) for the ISHAGE one, and 5.17 x 10(6)/kg (range 2-599) for our protocol. The median time to ANC and PLT engraftment was 11 (range 9-24) and 20 (range 10-70) days, respectively. Our protocol achieved the best correlation between CD34+ cells/kg and time to ANC/PLT recovery according to the Spearman's rank test (r = -40 and P < 0. 015 for ANC, r= -46 and P = 0.005 for PLT). We conclude that (1) CD45 does not appear the ideal partner of HPCA-2 for determination of hematopoietic progenitors in mobilized peripheral blood; and (2) for clinical application, a single staining with 8G12 appears simple, reliable and feasible when rigorous procedures for sample preparation and acquisition are followed and an adequate software for multiparametric analysis is available.

Multiparametric analysis for the enumeration of CD34+ cells from bone marrow and stimulated peripheral blood.

Determination of CD34+ cells was performed in bone marrow and G-CSF mobilised peripheral blood samples. We adopted three different protocols of analysis: the Milan/Mulhouse protocol, the ISHAGE guidelines for CD34+ cell determination and our own protocol based upon the use of PAINT-A-GATEPRO software analysis program. An excellent correlation was demonstrated between the three methods (r2 0.98); however the analysis of variance showed a statistically significant difference between the results generated with the three methods (P=0.001). The differences between the three procedures are discussed with a special focus on the value of CD34+dim cells and the role of CD45 in the setting of a double staining. We have in fact identified a minor subset (CD34+CD38+CD45-) which would go unrecognised based upon its CD45 negativity.

Red blood cell depletion of cord blood using hydroxyethylstarch double sedimentation: analysis of 40 cases.

Cord blood has been shown to successfully reconstitute haematopoiesis following allogeneic transplantation in a variety of disorders. A major drawback of cord blood has been the risk of transfusion reaction secondary to ABO incompatibility and reduction in the stem cell pool if cord blood is manipulated to remove red cells. We report our experience on red blood cell depletion of cord blood (CB) with hydroxyethylstarch (HES) double sedimentation. The nucleated and mononucleated cell recovery passed from 78.4% at 90 min to 92.9% at 180 min and from 85% at 90 min to 96% at 180 min, respectively. The overall recovery of CCD34+ cells and of haemopoietic progenitors (CFU-GM) was 90.5% and 83.8%, respectively. The data indicate that HES double sedimentation is a simple and effective technique for cord blood manipulation, but further studies are necessary to evaluate the clonogenic progenitor recovery after thawing.

Efficacy and safety of human leucocyte interferon-alpha treatment in patients younger than 60 years of age with polycythaemia vera.

OBJECTIVES: To evaluate the therapeutic activity and toxicity of human leucocyte interferon-alpha (lIFN-alpha) in patients with polycythaemia vera (PV) aged less than 60 years. DESIGN: An open clinical study. SETTING: Department of Medical Sciences, Regina Apostolorum Hospital, Albano Laziale, and Chair of Haematology, University of Rome 'Tor Vergata', S. Eugenio Hospital, Rome, Italy. SUBJECTS: Fourteen patients with PV and aged < 60 years who had active disease as indicated by the need for phlebotomy and/or cytoreductive therapy. INTERVENTIONS: lIFN-alpha administered subcutaneously at the starting dose of 3 MU thrice weekly. The interferon dose could be escalated to six MU thrice weekly if it was well tolerated and disease was not controlled after three months of treatment at the lower dose. MAIN OUTCOME MEASURES: Change in phlebotomy requirements, spleen size, pruritus score and haematological parameters after 6 months of treatment. Evaluation of lIFN-alpha side effects. RESULTS: Complete or partial disease control was achieved in 13 patients. Six patients achieved a complete response (CR) and four a partial response (PR) after 3 months of therapy. Dose escalation in partial or nonresponders resulted in two patients switching from a status of PR to CR, and three other patients achieving a partial response after being unresponsive to the lower dosage. Human leucocyte interferon-alpha therapy significantly improved (P < 01) phlebotomy requirements, the degree of splenomegaly, pruritus scores, iron stores and MCV values, and platelet and leucocyte counts. A mild flu-like syndrome (low-grade fever, nausea and myalgias) appeared during the early phase of therapy in the majority of patients, but no patient had to discontinue lIFN-alpha because of intolerance. CONCLUSIONS: Subcutaneous human leucocyte interferon-alpha appears an effective and well tolerated therapy in the management of PV-associated myeloproliferation and pruritus in patients aged less than 60 years.

Minimally differentiated acute myeloid leukemia (AML-M0): a distinct clinico-biologic entity with poor prognosis.

FAB proposals for the diagnosis of AML-M0 represent the formal recognition of a distinct entity which has been described over the past few years by several authors and called minimally differentiated acute myeloid leukemia. By definition, AML-M0 includes acute leukemias which do not fit morphological and cytochemical criteria for the diagnosis of AML, and for which myeloid lineage assignment can be made by immunological assay showing positivity for MPO, CD13, and CD33 and negativity for lymphoid markers. Involvement of an early myeloid progenitor in the leukemic process is a possible theory hypothesized to explain the existence of such a form. Validity of this assumption has been based on the observation that AML-M0 frequently bears "stem cell" markers such as CD34, HLA-DR, Tdt, CD7, and promiscuous IgH/TCR gene rearrangements, which are thought to occur in uncommitted cells. Finally, AML-M0 very frequently carries cytogenetic abnormalities common to MDS or secondary AML, such as -5/5q- or -7/7q- deletions and or complex karyotype. In our experience, AML-M0 is also very often associated with the MDR phenotype, which in turn has been found strictly linked to "stem cell" features, especially in MDS. These biological aspects, altogether, translate into a very unfavorable prognosis, confirming even from a clinical point of view that AML-M0 is a distinct entity. In conclusion, "stem cell" markers, MDR phenotype, complex chromosome lesions, frequent occurrence in elderly patients, and intrinsic chemoresistance characterize AML-M0 and indicate the need for tailored treatments, possibly involving the use of MDR modulators and/or differentiating agents.

First report of t(8;21)(q22;q22) in a case of de novo acute monoblastic leukemia.

Here we describe the case of a 30-year-old man with a diagnosis of de novo acute monoblastic leukemia (FAB M5a), whose karyotype analysis revealed the presence of the translocation (8;21)(q22;q22) as the sole chromosome anomaly. In spite of the rather good prognosis patients suffering from acute leukemia and carrying this translocation are supposed to have, our patient had a very poor outcome, including an early relapse resistant to any treatment and meningeal localization. Death occurred within 5 months from diagnosis. To our knowledge this is the first report of t(8;21)(q22;q22) in de novo acute monoblastic leukemia.

Diagnosis of acute myeloid leukemia and system Coulter VCS.

BACKGROUND: The aim of this study was to evaluate the possible contribution VCS could make in a hematological laboratory for the diagnosis of acute myeloid leukemia (AML). MATERIALS AND METHODS: Peripheral blood samples from 42 AML patients and 58 normal donors were analyzed by flow cytometry with the VCS. Normal and leukemic peripheral blood samples were tested to establish a correlation between VCS data and the reference manual method. We evaluated the sensitivity threshold of the VCS for blast cell detection in progressively diluted samples. We looked at a correlation between different scatterplots and flags and the FAB classification of acute myeloid leukemia in order to identify a characteristic VCS image for each subtype. Thirty-four bone marrow samples (18 normal donors and 16 leukemic patients) were analyzed by the VCS system to demonstrate a characteristic scattergram distribution. Further, we tried to compare scatterplots to the flags of leukemic bone marrow samples and, finally, we compared VCS scatterplots with aberrant antigen expression in AML cases. RESULTS AND CONCLUSIONS: Overall VCS specificity was 93.1% (54/58) in peripheral blood samples; sensitivity was 100% (42/42) and VCS efficiency was 96%. In AML the characteristic X6 flag was observed in 95.23% of the cases (40/42). In peripheral samples discrimination was made between AML M1 with agranular blasts > 50% of the non erythroid cells (NEC), M4, M5 on the one hand, and AML M1 with granular blasts > 50% of NEC, M2, M3 on the other: the X5 flag was often present in the second group because of the different localization of the cells (p = 0.001). In all normal bone marrow samples we observed granuloblasts in different maturation stages in the neutrophil region of the DF1 VCS scatterplot corresponding to the X5X6 flags or, rarely, to the X5X6X1, because of the presence of immature erythroid cells. This association X5X6 was never observed alone in patients affected by AML. In our study, it was difficult to identify peculiar scatterplots and alarms for each FAB class of AML. Nevertheless, we observed that in all M4 and M5 FAB cases the blastic cells both in the peripheral blood and in the bone marrow samples were located in the monocyte region, with the frequent presence of the X3 flag often associated with the X6 flag. Eight out of the 16 AML bone marrow samples (1 FAB M0, 1 M2, 1 M3, 2 M4, 3 M5) showed the X2 flag and partial localization of blasts in the lymphoid region. In all these cases the presence of some small blastic cells with agranular cytoplasm was confirmed by morphological observation and cytochemical stainings.

Treatment of multiple myeloma with autologous blood stem cell transplantation. Preliminary results of an Italian multicentric pilot study.

Starting from May, 1991, 35 untreated myeloma patients entered a multicentric pilot study to evaluate the feasibility of a program of PBSC transplantation for previously untreated myeloma patients. The schedule was as follows: 2 cycles of VAD followed by CY, 7 g/mq+G-CSF (Granulokine, Roche) for 14 days, to increase and collect PBSC. The subsequent conditioning regimen was Melphalan+Busulfan followed by G-CSF. As maintenance R alpha-2 IFN was given, until relapse. The median follow-up is 14 months (4-22). On April 1993, 34 patients received at least 2 cycles of VAD, 27 were submitted to PBSC collection, 22 received conditioning regimen plus PBSC and 16 of them are in the maintenance treatment with IFN. Considering 28 patients for an intention to treat evaluation (35-7 in treatment), responding patients are 71% with 46% who achieved CR. White cells and platelets raised to > 1000/mmc and > 50,000/mmc after a median period of 10 and 13 days, from CY, and 11 and 14 days from transplant, respectively. Two patients relapsed, 2 others died while in PR because of CMV epatitis and candida pneumonia. The median number of CD34+ cells and CFU-GM was 24.75 x 10(6)/kg b.w. and 28.1 x 10(4)/kg b.w. respectively. In conclusion this treatment seems to be feasible and with low toxicity, but a longer follow-up is needed to evaluate the progression free survival of the high proportion of responding patients that we observed.

Concentration of human hematopoietic stem cells in bone marrow transplantation: results of a multicenter study using Baxter CS 3000 plus cell separator.

Preliminary BM processing to produce an enriched MNC fraction from large BM volumes improves subsequent pharmacological and/or immunological "ex vivo" treatment and cryopreservation. We detail on a multicenter study (6 Transplant Centers) performed to establish an effective and reliable protocol using a CS 3000 continuous flow separator on a large series of BM processed for autologous (96) and allogeneic (12) transplantation. The reduction in volume was 78.6 + 7.2% while 28.9 + 12.4% of the original nucleated cells were found in the final product. A mean of 84.3 + 13.2% of the staring MNC was yielded in a fraction containing over 81% MNC. Cloning efficiency indicated than the final graft was highly enriched in progenitor cells committed to the granulocyte/macrophage pathway (> 100%) as assessed in vitro (CFU-GM). Removal of RBC and PLT was 98.3 + 1.1 and 37.7 + 14.6%, respectively. The mean dose of MNC and CFU-GM was 0.6 + 0.37 x 10(8) and 0.96 + 1 x 10(5) recipient weight. The entire process was accomplished in 87.5 + 20 min. We concluded that this automated device is a simple and reproducible method for BM processing suitable as first step for further "ex vivo" automated negative and/or positive cell selections.

A metastatic breast carcinoma presenting as autoimmune hemolytic anemia.

The authors describe the case of a 75-year-old female who was hospitalized for anemia of unknown origin. Physical examination revealed a swelling in the right mammary region, where a mastectomy scar was present from surgery for a breast carcinoma. On admission, laboratory tests disclosed anemia (Hb, 8.5 g/dl), with a reticulocyte count of 65,000/mm3 and slightly increased bilirubin. Immunohematologic study revealed the presence of a red cell autoantibody with anti-D specificity in the serum and in the eluate from the patient's erythrocytes. A biopsy of the swelling was performed and histologic examination showed the presence of metastatic cells of breast carcinoma. The patient was given chemotherapy and radiotherapy. At this writing the anemia was absent, the immunohematologic study was negative, the swelling was greatly reduced, and no other metastatic lesions of breast carcinoma were present.
