RESUMO

Medicinal plants are the primary raw materials used in the production of medicinal products all over the world. As a result, more study on plants with therapeutic potential is required. The tropical tree Ziziphus spina belongs to the Rhamnaceae family. Biological reports and traditional applications including management of diabetes and treatment of malaria, digestive issues, typhoid, liver complaints, weakness, skin infections, urinary disorders, obesity, diarrhoea, and sleeplessness have all been treated with different parts of Z. spina all over the globe. The plant is identified as a rich source of diverse chemical compounds. This study is a comprehensive yet detailed review of Z. spina based on major findings from around the world regarding ethnopharmacology, biological evaluation, and chemical composition. Scopus, Web of Science, BioMed Central, ScienceDirect, PubMed, Springer Link, and Google Scholar were searched to find published articles. From the 186 research articles reviewed, we revealed the leaf extract to be significant against free radicals, microbes, parasites, inflammation-related cases, obesity, and cancer. Chemically, polyphenols/flavonoids were the most reported compounds with a composition of 66 compounds out of the total 193 compounds reported from different parts of the plant. However, the safety and efficacy of Z. spina have not been wholly assessed in humans, and further well-designed clinical trials are needed to corroborate preclinical findings. The mechanism of action of the leaf extract should be examined. The standard dose and safety of the leaf should be established.

RESUMO

Garcinia kola belongs to the Garcinia genus of the Clusiaceae family and Malpighiales order. It contains more than 180 members all over the globe. It is found all over Asia and in tropical African countries. In Africa, traditionally, G kola is used to manage and treat cancer, diabetes, malaria, analgesics, hypertension, and other numerous ailments. This review aimed to comprehensively update relevant information regarding the pharmacological potential of Garcinia kola. Electronic databases such as ScienceDirect, PubMed, Wiley, Google Scholar, Hindawi, and Springer extracted valuable information from original scientific research papers. Inclusion Criteria. Antioxidant, antimicrobial, antidiabetic, antibacterial, medications, antiviral, traditional medicine, ethnopharmacology, toxicity, cytotoxic action, chemical composition, mineral elements, GCMS analysis, and any other related phrases were used as filters to find studies. Exclusion Criteria. Data from questionable online sources, as well as thesis reports and review publications, were excluded from this investigation. The investigation revealed that seeds of G. kola are very efficient as antioxidant, antimicrobial, antidiabetic, antihypertension, antianalgesic, and anti-inflammatory. The study also found that too much consumption of the seeds caused low fertility and toxicity. However, the safety and efficacy of G. kola have not been wholly assessed in humans, and further well-designed clinical trials are needed to corroborate preclinical findings. The mechanism of action of the seed extract should be examined. The standard dose and safety of the seed should be established.

RESUMO

Morinda elliptica L. (Rubiaceae) is a phytomedicinal herb, used to treat gastrointestinal complications in Peninsular Malaysia. The study evaluates the in vivo hepatoprotective activity of ethanolic extract of M. elliptica stem in thioacetamide (TAA) induced liver fibrosis in male Sprague Drawly rats. Thirty adult rats were divided into five groups of six rats each. Rats of the normal control group received intraperitoneal injections (i. p.) of vehicle 10% Tween-20, 5 ml/kg, and hepatotoxic group 200 mg/kg TAA three times per week respectively. Three supplementary groups were treated with TAA plus daily oral silymarin (50 mg/kg) or M. elliptica (250 or 500 mg/kg). After 8 weeks of treatment, all rats were sacrificed. Liver fibrosis was assessed by gross macroscopic and microscopic tissue analysis, histopathological, and biochemical analysis. The livers of the TAA treated group showed uniform coarse granules, hepatocytic necrosis with lymphocytes infiltration. Contrary, the livers of M. elliptica treated groups (250 and 500 mg/kg) were much smoother and the cell damage was much lesser. The livers of M. elliptica treated groups rats showed elevated activity of SOD and CAT with a significant decrease in MDA level at p < .0001. The level of liver damage parameters, that is, ALP, ALT, and AST, bilirubin, total protein, and albumin were restored to the normal comparable to silymarin. M. elliptica stem extract significantly promoted normal rat liver architecture with significant perfections in biochemical parameters. The molecular contents of M. elliptica with hepatoprotective influence could be discovered, is the future prospective of this study.

RESUMO

The development of hematopoietic stem cell transplantation (HSCT) programs can face significant challenges in most developing countries because such endeavors must compete with other government health care priorities, including the delivery of basic services. While this is may be a limiting factor, these countries should prioritize development of the needed expertise to offer state of the art treatments including transplantation, by providing financial, technological, legal, ethical and other needed support. This would prove beneficial in providing successful programs customized to the needs of their population, and potentially provide long-term cost-savings by circumventing the need for their citizens to seek care abroad. Costs of establishing HSCT program and the costs of the HSCT procedure itself can be substantial barriers in developing countries. Additionally, socioeconomic factors intrinsic to specific countries can influence access to HSCT, patient eligibility for HSCT and timely utilization of HSCT center capabilities. This report describes recommendations from the Worldwide Network for Blood and Marrow Transplantation (WBMT) for establishing HSCT programs with a specific focus on developing countries, and identifies challenges and opportunities for providing this specialized procedure in the resource constrained setting.

RESUMO

Several studies have reported an association between CMV reactivation and a decreased incidence of relapse for AML after adult donor allogeneic hematopoietic cell transplantation (HCT). Limited data, however, are available on the impact of CMV reactivation on relapse after cord blood (CB) stem cell transplantation. The unique combination of higher incidence of CMV reactivation in the seropositive recipient and lower incidence of graft versus host disease (GvHD) in CB HCT permits a valuable design to analyze the impact of CMV reactivation. Data from 1684 patients transplanted with CB between 2003 and 2010 for AML and ALL were analyzed. The median time to CMV reactivation was 34 days (range: 2-287). CMV reactivation and positive CMV serology were associated with increased non-relapse mortality (NRM) among both AML and ALL CB recipients (reactivation, AML: relative risk (RR) 1.41 (1.07-1.85); ALL: 1.60 (1.14-2.23); Serology, AML: RR 1.39 (1.05-1.85), ALL: RR 1.61 (1.18-2.19)). For patients with ALL, but not those with AML, this yielded inferior overall survival (P<0.005). Risk of relapse was not influenced by CMV reactivation or positive CMV serostatus for either disease.

RESUMO

Parainfluenza virus (PIV) may cause life-threatening pneumonia in allogeneic hematopoietic stem cell transplant (HSCT) recipients. Currently, there are no proven effective therapies. We report the use of inhaled DAS181, a novel sialidase fusion protein, for treatment of PIV type 3 pneumonia in two allogeneic hematopoietic SCT recipients with respiratory failure.

RESUMO

The impact of extramedullary disease (EMD) in AML on the outcomes of allogeneic hematopoietic cell transplantation (alloHCT) is unknown. Using data from the Center for International Blood and Marrow Transplant Research, we compared the outcomes of patients who had EMD of AML at any time before transplant, with a cohort of AML patients without EMD. We reviewed data from 9797 AML patients including 814 with EMD from 310 reporting centers and 44 different countries, who underwent alloHCT between and 1995 and 2010. The primary outcome was overall survival (OS) after alloHCT. Secondary outcomes included leukemia-free survival (LFS), relapse rate and treatment-related mortality (TRM). In a multivariate analysis, the presence of EMD did not affect either OS (hazard ratio 1.00, 95% confidence interval (CI) 0.91-1.09), LFS (0.98, 0.89-1.09), TRM (relative risk 0.92, 95% CI 0.80-1.16, P=0.23) or relapse (relative risk=1.03, 95% CI, 0.92-1.16; P=0.62). Furthermore, the outcome of patients with EMD was not influenced by the location, timing of EMD, or intensity of conditioning regimen. The presence of EMD in AML does not affect transplant outcomes and should not be viewed as an independent adverse prognostic feature.

RESUMO

Recent studies support the use of bortezomib-based therapies in light chain amyloidosis (AL). We performed a retrospective analysis of the safety, efficacy and long-term survival (median follow-up 3 years) after bortezomib-based treatment in 28 consecutive patients with de novo AL deemed ineligible at initial presentation. The first 14 patients received bortezomib and dexamethasone (VD), and the second 14 patients received cyclophosphamide, bortezomib and dexamethasone (CVD; CyBorD). Both regimens were well tolerated with no treatment-related mortality. The overall hematological response (HR) rate was 93% in both the groups. Median time to response was shorter in the CVD group (39 days vs 96 days in the VD group; P=0.002). Hematological and organ responses induced with bortezomib-based therapy enabled 8 (33%) of initially transplant ineligible patients to undergo autologous hematopoietic stem cell transplantation (AHCT), including 4 patients with cardiac stage III or IV. Seven of the eight patients (88%) who underwent subsequent AHCT achieved sustained HR at a median of 33 months posttransplant. These data suggest that bortezomib-based induction followed by AHCT is a viable therapeutic strategy for transplant-ineligible AL. Larger, multicenter prospective trials are necessary to confirm our findings.

RESUMO

Autologous hematopoietic cell transplantation (Auto-HCT) is commonly an in-patient procedure. However, Auto-HCT is increasingly being offered on an outpatient basis. To better characterize the safety of outpatient Auto-HCT, we compared the outcome of 230 patients who underwent Auto-HCT on an in-patient vs outpatient basis for myeloma or lymphoma within a single transplant program. All outpatient transplants occurred in a cancer center day hospital. Hematopoietic recovery occurred earlier in the outpatient cohort, with median time to neutrophil recovery of 10 vs 11 days (P<0.001) and median time to platelet recovery of 19 vs 20 days (P=0.053). Fifty-one percent of the outpatient cohort never required admission, with this percentage increasing in later years. Grade 3-4 non-hematologic toxicities occurred in 29% of both cohorts. Non-relapse mortality at 1 year was 0% in the outpatient cohort and 1.5% in the in-patient cohort (P=0.327). Two-year PFS was 62% for outpatient vs 54% for in-patient (P=0.155). One- and two-year OS was 97% and 83% for outpatient vs 91% and 80% for in-patient, respectively (P=0.271). We conclude that, with daily outpatient evaluation and aggressive supportive care, outpatient Auto-HCT can result in excellent outcomes for myeloma and lymphoma patients.

RESUMO

Alternative donor transplantation is increasingly used for high-risk lymphoma patients. We analyzed 1593 transplant recipients (2000-2010) and compared transplant outcomes in recipients of 8/8 allele HLA-A, -B, -C and DRB1 matched unrelated donors (MUDs; n=1176), 7/8 allele HLA mismatched unrelated donors (MMUDs; n=275) and umbilical cord blood donors (1 or 2 units UCB; n=142). Adjusted 3-year non-relapse mortality of MMUD (44%) was higher as compared with MUD (35%; P=0.004), but similar to UCB recipients (37%; P=0.19), although UCB had lower rates of neutrophil and platelet recovery compared with unrelated donor groups. With a median follow-up of 55 months, 3-year adjusted cumulative incidence of relapse was lower after MMUD compared with MUD (25% vs 33%, P=0.003) but similar between UCB and MUD (30% vs 33%; P=0.48). In multivariate analysis, UCB recipients had lower risks of acute and chronic GVHD compared with adult donor groups (UCB vs MUD: hazard ratio (HR)=0.68, P=0.05; HR=0.35; P<0.001). Adjusted 3-year OS was comparable (43% MUD, 37% MMUD and 41% UCB). These data highlight the observation that patients with lymphoma have acceptable survival after alternative donor transplantation. MMUD and UCB can extend the curative potential of allotransplant to patients who lack suitable HLA matched sibling or MUD.

RESUMO

The efficacy of reduced intensity conditioning (RIC) allogeneic hematopoietic cell transplantation (HCT) for Philadelphia chromosome positive (Ph+) acute lymphoblastic leukemia (ALL) is uncertain. We analyzed 197 adults with Ph+ ALL in first complete remission; 67 patients receiving RIC were matched with 130 receiving myeloablative conditioning (MAC) for age, donor type and HCT year. Over 75% received pre-HCT tyrosine kinase inhibitors (TKIs), mostly imatinib; 39% (RIC) and 49% (MAC) were minimal residual disease (MRD)(neg) pre-HCT. At a median 4.5 years follow-up, 1-year transplant-related mortality (TRM) was lower in RIC (13%) than MAC (36%; P=0.001) while the 3-year relapse rate was 49% in RIC and 28% in MAC (P=0.058). Overall survival (OS) was similar (RIC 39% (95% confidence interval (CI) 27-52) vs 35% (95% CI 27-44); P=0.62). Patients MRD(pos) pre-HCT had higher risk of relapse with RIC vs MAC (hazard ratio (HR) 1.97; P=0.026). However, patients receiving pre-HCT TKI in combination with MRD negativity pre-RIC HCT had superior OS (55%) compared with a similar MRD population after MAC (33%; P=0.0042). In multivariate analysis, RIC lowered TRM (HR 0.6; P=0.057), but absence of pre-HCT TKI (HR 1.88; P=0.018), RIC (HR 1.891; P=0.054) and pre-HCT MRD(pos) (HR 1.6; P=0.070) increased relapse risk. RIC is a valid alternative strategy for Ph+ ALL patients ineligible for MAC and MRD(neg) status is preferred pre-HCT.

RESUMO

Desmoplastic small round cell tumor of the peritoneum (DSRCTP) is a rare, frequently fatal tumor. This retrospective study, based on CIBMTR registry data, describes the largest reported cohort of DSRCTP patients who have undergone Auto-SCT. The probabilities of disease-free survival (DFS) at 1 year for patients in CR and not in CR were 75% (95% confidence interval: 48-94%) and 35% (15-59%), respectively. The probability of OS at 3 years was 57% (29-83%) and 28% (9-51%) for patients in CR and not in CR, respectively. Median survival for the entire cohort was 31 months (36 months and 21 months for those in CR and not in CR, respectively). Engraftment at 42 days was 97% (88-100%). Treatment-related mortality was low, with only one death in the first 100 days. Auto-SCT is a tolerable approach in patients with DSRCTP, with the greatest benefit seen in those patients who obtain CR. For those not in CR, the median OS in this series is greater than previously reported (21 months vs 17 months), suggesting Auto-SCT is useful in prolonging DFS and OS, even in patients with residual or persistent disease pre-transplant.

RESUMO

BACKGROUND: Knowledge of independent, baseline risk factors for catheter-related thrombosis (CRT) may help select adult cancer patients who are at high risk to receive thromboprophylaxis. OBJECTIVES: We conducted a meta-analysis of individual patient-level data to identify these baseline risk factors. PATIENTS/METHODS: MEDLINE, EMBASE, CINAHL, CENTRAL, DARE and the Grey literature databases were searched in all languages from 1995 to 2008. Prospective studies and randomized controlled trials (RCTs) were eligible. Studies were included if original patient-level data were provided by the investigators and if CRT was objectively confirmed with valid imaging. Multivariate logistic regression analysis of 17 prespecified baseline characteristics was conducted. Adjusted odds ratios (ORs) and 95% confidence intervals (CIs) were estimated. RESULTS: A total sample of 5636 subjects from five RCTs and seven prospective studies was included in the analysis. Among these subjects, 425 CRT events were observed. In multivariate logistic regression, the use of implanted ports as compared with peripherally implanted central venous catheters (PICCs), decreased CRT risk (OR, 0.43; 95% CI, 0.23-0.80), whereas past history of deep vein thrombosis (DVT) (OR, 2.03; 95% CI, 1.05-3.92), subclavian venipuncture insertion technique (OR, 2.16; 95% CI, 1.07-4.34) and improper catheter tip location (OR, 1.92; 95% CI, 1.22-3.02), increased CRT risk. CONCLUSIONS: CRT risk is increased with use of PICCs, previous history of DVT, subclavian venipuncture insertion technique and improper positioning of the catheter tip. These factors may be useful for risk stratifying patients to select those for thromboprophylaxis. Prospective studies are needed to validate these findings.

RESUMO

Chronic beryllium disease is an occupationally acquired granulomatous lung disease similar to sarcoidosis. It is caused by exposure to beryllium in genetically susceptible persons. It should be suspected in patients with beryllium exposure who present with pulmonary symptoms or have a positive screening blood beryllium-specific lymphocyte proliferation test. The diagnosis is confirmed by the finding of granulomas on transbronchial biopsy in the appropriate clinical and epidemiologic setting. Although there is no cure, treatment with corticosteroids is usually beneficial. In view of the potential side effects, treatment is reserved for patients with symptoms or a decline in pulmonary function.

RESUMO

Within a 40-month period ending in June 1992, we used the transseptal approach in performing mitral valve surgery on 18 patients. The patients selected had 1 or more of the following indications: small left atrium; adhesions from previous cardiac surgery or rheumatic activity; large, organized left atrial thrombus: the need for concomitant tricuspid valve surgery; or any combination of these factors. We made the septal incision in the long axis of the fossa ovalis and extended it anteriorly and posteriorly, taking care not to injure either the aortic root or the coronary sinus. In 15 patients, we easily obtained good mitral exposure; in 3, exposure was still difficult. One patient died, but the cause of death was not related to the surgical approach. Although none of our patients had early postoperative cardiac arrhythmias, the small number in our series and the short follow-up time prevent us from predicting the effect of this incision on late postoperative cardiac arrhythmias. Therefore, we recommend limiting the transseptal approach to complex reoperations and to operations necessitating right atriotomy for concomitant procedures. It is also very useful in patients with a large, organized left atrial thrombus. Under these conditions, we conclude that using the transseptal approach for mitral valve surgery is a simple, safe, and time-saving technique.

RESUMO

Intralesional corticosteroid injections were performed in 31 hemangiomas in 30 infants aged 1 to 10 months at first injection. One to five injections were given, spaced 6 weeks apart. Lesions were located throughout the head and neck region, except one that was on the buttock. A mixture of betamethasone acetate and triamcinolone acetonide was used. Four lesions (13 percent) virtually disappeared, ten (32 percent) showed greater than 50 percent reduction in volume, ten (32 percent) showed definite but less than 50 percent reduction in volume, and seven (23 percent) showed little or no decrease in size. None showed further growth. All injections were performed without anesthesia, and there were not significant complications. We conclude that intralesional corticosteroid injections are safe and effective in properly selected infants with hemangiomas.

RESUMO

More than 111 patients with traumatic diaphragmatic hernia (TDH) were treated in a 5 1/2-year period; eight (7.2%) were first recognized more than 30 days postinjury. All were men, and their average age was 33.4 years. Seven injuries were on the left side; one was on the right side. The mechanism of injury was equally divided between penetrating and blunt trauma. Chest roentgenographic abnormalities were seen in all patients. Visceral reduction and diaphragmatic repair, despite strangulation in four patients, was accomplished without mortality and with minimal morbidity. Delayed presentation of TDH is reviewed, emphasizing diagnostic features encountered in the emergency department (ED).

RESUMO

Indomethacin-treated bovine iris-ciliary body microsomes (IBIM) have been studied for their ability to convert PG endoperoxides into either thromboxane-A2 (TxA2)-like or prostacyclin (PGI2)-like activity. The biological activity of the ocular tissue microsomes were compared with either indomethacin-treated human platelet microsomes (for TxA2-like activity) or rabbit aorta microsomes (for PGI2-like activity) under appropriate incubation conditions. No evidence could be found for the formation of TxA2-like activity from PG endoperoxides by the IBIM. In contrast, when the IBIM were incubated with PGH2 for 1 min at 22 degrees C without cofactors, PGI2-like activity was produced, causing profound relaxation of the isolated dog coronary artery preparation without contracting the rabbit aorta and inhibiting arachidonic acid-induced platelet aggregation. Equivalent quantities of boiled IBIM failed to alter the biological activity of PGH2 under identical conditions. Tranylcypromine (500 microgram/ml) completely abolished the appearance of PGI2-like activity. Furthermore, the PGI2-like activity found was stable for 10 min at 22 degrees C at pH 8.5 but completely lost under similar conditions at pH 5.5. It is concluded that microsomal preparations of normal bovine iris-ciliary body can synthesize PGI2-like activity in substantial amounts but not TxA2-like activity.
