The oral histone deacetylase (HDAC) inhibitor (vorinostat) is safe and results in low incidence of acute graft-versus-host disease (GVHD) after reduced-intensity conditioning, related donor hematopoietic cell transplantation (HCT). However, its safety and efficacy in preventing acute GVHD in settings of heightened clinical risk that use myeloablative conditioning, unrelated donor (URD), and methotrexate are not known. We conducted a prospective, phase 2 study in this higher-risk setting. We enrolled 37 patients to provide 80% power to detect a significant difference in grade 2 to 4 acute GVHD of 50% compared with a reduction in target to 28%. Eligibility included adults with a hematological malignancy to receive myeloablative HCT from an available 8/8-HLA matched URD. Patients received GVHD prophylaxis with tacrolimus and methotrexate. Vorinostat (100 mg twice daily) was started on day -10 and continued through day +100 post-HCT. Median age was 56 years (range, 18-69 years), and 95% had acute myelogenous leukemia or high-risk myelodysplastic syndrome. Vorinostat was safe and tolerable. The cumulative incidence of grade 2 to 4 acute GVHD at day 100 was 22%, and for grade 3 to 4 it was 8%. The cumulative incidence of chronic GVHD was 29%; relapse, nonrelapse mortality, GVHD-free relapse-free survival, and overall survival at 1 year were 19%, 16%, 47%, and 76%, respectively. Correlative analyses showed enhanced histone (H3) acetylation in peripheral blood mononuclear cells and reduced interleukin 6 ( P = .028) and GVHD biomarkers (Reg3, P = .041; ST2, P = .002) at day 30 post-HCT in vorinostat-treated subjects compared with similarly treated patients who did not receive vorinostat. Vorinostat for GVHD prevention is an effective strategy that should be confirmed in a randomized phase 3 study.

Full Text Available IntroductionConditioning regimens preceding allogeneic stem cell transplantation (alloSCT can cause tissue damage and acceleration of the development of graft-versus-host disease (GVHD. T-cell-depleted alloSCT with postponed donor lymphocyte infusion (DLI may reduce GVHD, because tissue injury can be restored at the time of DLI. In this study, we investigated the presence of tissue injury and inflammation in skin during the period of hematologic recovery and immune reconstitution after alloSCT.MethodsSkin biopsies were immunohistochemically stained for HLA class II, CD1a, CD11c, CD40, CD54, CD68, CD86, CD206, CD3, and CD8. HLA class II-expressing cells were characterized as activated T-cells, antigen-presenting cells (APCs, or tissue repairing macrophages. In sex-mismatched patient and donor couples, origin of cells was determined by multiplex analysis combining XY-FISH and fluorescent immunohistochemistry.ResultsNo inflammatory environment due to pretransplant conditioning was detected at the time of alloSCT, irrespective of the conditioning regimen. An increase in HLA class II-positive macrophages and CD3 T-cells was observed 12–24 weeks after myeloablative alloSCT, but these macrophages did not show signs of interaction with the co-localized T-cells. In contrast, during GVHD, an increase in HLA class II-expressing cells coinciding with T-cell interaction was observed, resulting in an overt inflammatory reaction with the presence of activated APC, activated donor T-cells, and localized upregulation of HLA class II expression on epidermal cells. In the absence of GVHD, patient derived macrophages were gradually replaced by donor-derived macrophages although patient-derived macrophages were detectable even 24 weeks after alloSCT.ConclusionConditioning regimens cause tissue damage in the skin, but this does not result in a local increase of activated APC. In contrast to the inflamed situation in GVHD, when interaction takes place between

Purpose Several open-label randomized studies have suggested that in vivo T-cell depletion with anti-T-lymphocyte globulin (ATLG; formerly antithymocyte globulin-Fresenius) reduces chronic graft-versus-host disease (cGVHD) without compromising survival. We report a prospective, double-blind phase III trial to investigate the effect of ATLG (Neovii Biotech, Lexington, MA) on cGVHD-free survival. Patients and Methods Two hundred fifty-four patients 18 to 65 years of age with acute leukemia or myelodysplastic syndrome who underwent myeloablative HLA-matched unrelated hematopoietic cell transplantation (HCT) were randomly assigned one to one to placebo (n =128 placebo) or ATLG (n = 126) treatment at 27 sites. Patients received either ATLG or placebo 20 mg/kg per day on days -3, -2, -1 in addition to tacrolimus and methotrexate as GVHD prophylaxis. The primary study end point was moderate-severe cGVHD-free survival. Results Despite a reduction in grade 2 to 4 acute GVHD (23% v 40%; P = .004) and moderate-severe cGVHD (12% v 33%; P < .001) in ATLG recipients, no difference in moderate-severe cGVHD-free survival between ATLG and placebo was found (2-year estimate: 48% v 44%, respectively; P = .47). Both progression-free survival (PFS) and overall survival (OS) were lower with ATLG (2-year estimate: 47% v 65% [ P = .04] and 59% v 74% [ P = .034], respectively). Multivariable analysis confirmed that ATLG was associated with inferior PFS (hazard ratio, 1.55; 95% CI, 1.05 to 2.28; P = .026) and OS (hazard ratio, 1.74; 95% CI, 1.12 to 2.71; P = .01). Conclusion In this prospective, randomized, double-blind trial of ATLG in unrelated myeloablative HCT, the incorporation of ATLG did not improve moderate-severe cGVHD-free survival. Moderate-severe cGVHD was significantly lower with ATLG, but PFS and OS also were lower. Additional analyses are needed to understand the appropriate role for ATLG in HCT.

Full Text Available CONTEXT AND OBJECTIVE: Non-myeloablative hematopoietic stem cell transplantation (NMA-HSCT is performed in onco-hematological patients who cannot tolerate ablative conditioning because of older age or comorbidities. This approach does not completely eliminate host cells and initially results in mixed chimerism. Long-term persistence of mixed chimerism results in graft rejection and relapse. Involvement of graft-versus-host disease is concomitant with complete chimerism and graft-versus-tumor effect. The aim of this study was to evaluate the prevalence of chimerism in onco-hematological patients who underwent NMA-HSCT. DESIGN AND SETTING: Observational clinical study on chimerism status after human leukocyte antigen-identical NMA-HSCT at the Discipline of Hematology and Hemotherapy of Universidade Federal de São Paulo. METHODS: We sequentially analyzed the amplification of APO-B, D1S80, DxS52, FVW, 33.6, YNZ-2 and H-ras primers using variable number of tandem repeats (VNTR on 17 pairs and fluorescent in situ hybridization (FISH with the XY probe and SRY primer on 13 sex-unmatched pairs. RESULTS: The informativeness of the primers using VNTR was 60% for APO-B, 75% D1S80, 36% DxS52, 14% FVW, 40% YNZ-22 and 16% H-ras. The SRY primer was informative in female receptors with male donors. The XY-FISH method was informative in 100% of the sex-unmatched pairs. CONCLUSION: These methods were sensitive and informative. In VNTR, the association of APO-B with D1S80 showed 88% informativeness. The quantitative FISH method was more sensitive, but had the disadvantage of only being used for sex-unmatched pairs.

CD20 has been used as target molecule for low-dose as well as high-dose, myeloablative RIT of B-cell NHL. MCL is an especially aggressive, prognostically unfavorable form of B-cell NHL. The aim of this study was to investigate whether high-dose, myeloablative RIT with the 131 I-labeled chimeric anti-CD20 antibody C2B8 (rituxan, Mabthera, Roche) may be therapeutically more effective than conventional low-dose therapy in MCL. A total of twelve patients with chemorefractory or relapsed mantle cell lymphoma were studied so far (all of them having relapsed after high-dose chemotherapy, seven of them combined with 12 Gy TBI). A diagnostic-dosimetric study was performed with 10 mCi of 131 I-C2B8 at a protein dose of 2.5 mg/kg. In case of splenic pooling, the protein dose was increased until a more 'favorable' biodistribution was obtained. Therapy was performed with conventional (30-75 mCi; n=4) or myeloablative activities (261-515 mCi; n=8) of 131 I-C2B8 at the previously optimized protein dose, aiming at whole-body doses of ≤ 0.8 Gy (for low-dose RIT) or lung doses of ≤ 27 Gy (for high-dose RIT). Clinical follow-up was obtained for up to 42 months. Overall, in 11 patients the 2.5 mg/kg protein dose was used, whereas in one patient with marked splenomegaly, 10 mg/kg were necessary to overcome the splenic antigenic sink. In the high-dose patients, non-hematologic toxicity was restricted to mild to moderate nausea, fever, transient bilirubin or liver enzyme elevations. Despite thyroid blocking, 6/8 high-dose (in contrast to 0/4 low-dose) patients developed hypothyroidism, requiring thyroxine substitution at 6-18 months after RIT. The response rate in the low-dose arm was only 1(PR)/4, whereas 7/8 high-dose patients experienced complete and the remainder a partial remission. 6 high-dose patients are still in CR (one of them relapsed locally at 3 months, one systemically at 26 months after RIT), and 7 are still alive for up to 42+ months. In contrast to low-dose therapy

Myeloablative temozolomide enhances CD8⁺ T-cell responses to vaccine and is required for efficacy against brain tumors in mice.

Full Text Available Temozolomide (TMZ is an alkylating agent shown to prolong survival in patients with high grade glioma and is routinely used to treat melanoma brain metastases. A prominent side effect of TMZ is induction of profound lymphopenia, which some suggest may be incompatible with immunotherapy. Conversely, it has been proposed that recovery from chemotherapy-induced lymphopenia may actually be exploited to potentiate T-cell responses. Here, we report the first demonstration of TMZ as an immune host-conditioning regimen in an experimental model of brain tumor and examine its impact on antitumor efficacy of a well-characterized peptide vaccine. Our results show that high-dose, myeloablative (MA TMZ resulted in markedly reduced CD4(+, CD8(+ T-cell and CD4(+Foxp3(+ TReg counts. Adoptive transfer of naïve CD8(+ T cells and vaccination in this setting led to an approximately 70-fold expansion of antigen-specific CD8(+ T cells over controls. Ex vivo analysis of effector functions revealed significantly enhanced levels of pro-inflammatory cytokine secretion from mice receiving MA TMZ when compared to those treated with a lower lymphodepletive, non-myeloablative (NMA dose. Importantly, MA TMZ, but not NMA TMZ was uniquely associated with an elevation of endogenous IL-2 serum levels, which we also show was required for optimal T-cell expansion. Accordingly, in a murine model of established intracerebral tumor, vaccination-induced immunity in the setting of MA TMZ-but not lymphodepletive, NMA TMZ-led to significantly prolonged survival. Overall, these results may be used to leverage the side-effects of a clinically-approved chemotherapy and should be considered in future study design of immune-based treatments for brain tumors.

Pulmonary toxicities, including infectious pneumonia (IP) and idiopathic pneumonia syndrome (IPS), are serious side effects of total body irradiation (TBI) used for myeloablative conditioning. This study aimed to evaluate clinical factors associated with IP and IPS following TBI. Fifty-eight patients with hematologic malignancies who underwent TBI before allogeneic hematopoietic stem cell transplantation between 2005 and 2014 were reviewed. Most patients (91%) received 12 Gy in 1.5 Gy fractions twice a day. Pulmonary toxicities were diagnosed based on either radiographic evidence or reduced pulmonary function, and were subdivided into IP and IPS based on the presence or absence of concurrent infection. Pulmonary toxicities developed in 36 patients (62%); 16 (28%) had IP and 20 (34%) had IPS. IP was significantly associated with increased treatment-related mortality (p = 0.028) and decreased survival (p = 0.039). Multivariate analysis revealed that the risk of developing IPS was significantly higher in patients who received stem cells from a matched unrelated donor than from a matched sibling donor (p = 0.021; hazard ratio [HR] = 12.67; 95% confidence interval [CI], 1.46–110.30). Combining other conditioning agents with cyclophosphamide produced a higher tendency to develop IP (p = 0.064; HR = 6.19; 95% CI, 0.90–42.56). IP and IPS involve different risk factors and distinct pathogeneses that should be considered when planning treatments before and after TBI.

Thiotepa is an alkylating compound with an antineoplastic and myeloablative activity and can mimic the effect of radiation. However, it is unknown whether this new regimen could safely replace the long-established ones. This retrospective matched-pair analysis evaluated the outcome of adults with acute myeloid leukaemia in first complete remission who received myeloablative conditioning either with a thiotepa-based (n = 121) or a cyclophosphamide/total body irradiation-based (TBI; n = 358) regimen for allogeneic hematopoietic stem cell transplantation from an HLA-matched sibling or an unrelated donor. With a median follow-up of 44 months, the outcome was similar in both groups. Acute graft-versus-host disease grade II-IV was observed in 25% after thiotepa-containing regimen versus 35% after TBI (P = 0.06). The 2-yr cumulative incidence of chronic graft-versus-host disease was 40.5% for thiotepa and 41% for TBI (P = 0.98). At 2 yrs, the cumulative incidences of non-relapse mortality and relapse incidence were 23.9% (thiotepa) vs. 22.4% (TBI; P = 0.66) and 17.2% (thiotepa) vs. 23.3% (TBI; P = 0.77), respectively. The probabilities of leukaemia-free and overall survival at 2 yrs were not significantly different between the thiotepa and TBI groups, at 58.9% vs. 54.2% (P = 0.95) and 61.4% vs. 58% (P = 0.72), respectively. Myeloablative regimens using combinations including thiotepa can provide satisfactory outcomes, but the optimal conditioning remains unclear for the individual patient in this setting. © 2015 John Wiley & Sons A/S.

Patients with leukemia relapsing after allogeneic hematopoietic SCT have a dismal prognosis. A second SCT offers a further opportunity for cure, but has a high rate of treatment failure. To determine the utility of this option, we analyzed 59 consecutive patients relapsing after a myeloablative HLA-matched sibling T cell-depleted (TCD) SCT. Twenty-five patients (13 relapsing within 6 months and 12 relapsing between 6 and 170 months after the first SCT) received a T-replete second SCT. Thirty-eight patients relapsing early had a shorter survival than the 21 patients relapsing later (median 96 vs 298 days, P=0.0002). In patients relapsing early, the second SCT did not improve OS compared with patients receiving non-SCT treatments (median survival 109 vs 80 days, P=0.41). In patients relapsing late, despite an early trend in favor of second SCT, survival was comparable for patients receiving a second SCT compared with non retransplanted patients (median survival 363.5 vs 162 days, P=0.49). Disappointingly, our results do not demonstrate an important survival benefit for a second T-replete allogeneic SCT to treat relapse following a TCD SCT.

There are no well-defined studies of chronic kidney disease (CKD) among long-term survivors after hematopoietic SCT. A retrospective longitudinal study was conducted to characterize CKD in 77 subjects that had undergone myeloablative allogeneic SCT, all of whom had their serum creatinine (Cr) levels followed-up during the 10-year period after SCT. Their mean (range) survival time was 14.4 (10.5-20.2) years. CKD was defined as a persistent decrease in the Cr-based estimated glomerular filtration rate to below 60 mL/min/1.73 m². Acute kidney injury (AKI) was defined as an increase in Cr within the first 100 days after SCT, and its severity was classified into three stages according to the AKIN criteria. Kaplan-Meier and Cox proportional hazards regression analyses evaluated the association between AKI and the incidence of CKD. The cumulative incidence of CKD increased over time and reached 34% at 10 years. After adjusting for known risks for post-SCT CKD, each AKIN stage was strongly associated with the incidence of CKD. The incidence of CKD probably increases over time among subjects who are alive at >10 years after SCT. This study places a new emphasis on AKI as an important risk factor for CKD in post-SCT subjects.

Full Text Available The article focuses on aspects of T. gondii reactivation/reinfection in patients undergoing allogeneic hematopoietic stem cell transplantation (alloHSCT. We have observed 297 patients who received conditioning therapy and allogeneic grafts due to different oncohematological or lymphoproliferative diseases (1 to 60 years old, at a mediane of 19 years. Conditioning regimens were either myeloablative (35%, or non-myeloablative (65%. DNA diagnostics of T. gondii was performed on a regular basis at 0 to 6 months post-HSCT. IgG and IgM antibodies against T. gondii were determined in 78 patients before HSCT, as well as in their donors. T. gondii DNA post-transplant proved to be positive in 13% of blood specimens, 9% of cerebrospinal liquor samples, 11% of bronchoalveolar cell lavages, and in 5% of urine sediments. In adolescent patients (10 to 14 years old, an increased prevalence of T. gondii was found in patients who received myeloablative treatment (p = 0.01. When assessing posttransplant dynamics of T. gondii, we have revealed distinct increase in the pathogen excretion within 1st month after HSCT (p = 0.03. Finally, initial presence of IgG antibodies against T. gondii in the patients was associated with lower incidence of the pathogen reactivation post-transplant.

The components of therapy required for patients with INSS Stage 3 neuroblastoma and high-risk features remain controversial. A retrospective cohort design was used to determine if intensive chemoradiotherapy with purged autologous bone marrow rescue (ABMT) and/or 13-cis-retinoic acid (13-cis-RA) improved outcome for patients with high-risk neuroblastoma that was not metastatic to distant sites. We identified 72 patients with INSS Stage 3 neuroblastoma enrolled between 1991 and 1996 on the Phase 3 CCG-3891 randomized trial. Patients were analyzed on an intent-to-treat basis using a log-rank test. The 5-year event-free survival (EFS) and overall survival (OS) rates for patients with Stage 3 neuroblastoma were 55 +/- 6% and 59 +/- 6%, respectively (n = 72). Patients randomized to ABMT (n = 20) had 5-year EFS of 65 +/- 11% and OS of 65 +/- 11% compared to 41 +/- 11 (P = 0.21) and 46 +/- 11% (P = 0.23) for patients randomized to CC (n = 23), respectively. Patients randomized to 13-cis-RA (n = 23) had 5-year EFS of 70 +/- 10% and OS of 78 +/- 9% compared to 63 +/- 12% (P = 0.67) and 67 +/- 12% (P = 0.55) for those receiving no further therapy (n = 16), respectively. Patients randomized to both ABMT and 13-cis-RA (n = 6) had a 5-year EFS of 80 +/- 11% and OS of 100%. Patients with high-risk Stage 3 neuroblastoma have an overall poor prognosis despite aggressive chemoradiotherapy. Further studies are warranted to determine if myeloablative consolidation followed by 13-cis-RA maintenance therapy statistically significantly improves outcome.

A significant association between KIR genotype mismatching (KIR-B/x donor into KIR-AA recipient or vice versa) and cGVHD was found in both discovery (p = 0.001; SHR = 2.78; 95%CI: 1.50-5.17) and validation cohorts (p = 0.005; SHR = 2.61; 95%CI: 1.33-5.11). High incidence of cGVHD associated with KIR genotype mismatching was applicable

Allogeneic hematopoietic stem cell transplantation (allo-SCT) is a potentially curative treatment option for eligible patients with chronic lymphocytic leukemia (CLL). However, it is known that cure of CLL is only possible if a graft-versus-leukemia effect is present. Between 1994 and 2007, 48 adults underwent allo-SCT for poor-risk CLL in Sweden. Of these, ten (21%) patients aged 24-53 years (median: 46 years) received myeloablative conditioning (MAC), based on TBI and cyclophosphamide. All MAC patients had refractory, poorly controlled CLL before allo-SCT (partial remission in 9/10 patients and progressive disease in one). The cumulative incidence of acute graft-versus-host disease (GVHD) grades II-IV was 30%. Nine patients developed chronic GVHD; extensive in four. Rates of nonrelapse mortality at 1, 3 and 10 years were 0, 10 and 20%, respectively. Two patients relapsed 36 and 53 months after transplantation. Six patients were still alive after a median follow-up time of 11.5 years (range 5.9-13.7). The probabilities of relapse-free and overall survival from 1, 3 and 5 years after transplantation were 100, 90 and 70%, and 100, 90 and 80%, respectively. Nevertheless, our analysis of long-term outcome after MAC allo-SCT for CLL suggests that younger patients with poorly controlled CLL may benefit from MAC allo-SCT.

Background The components of therapy required for patients with INSS Stage 3 neuroblastoma and high risk features remain controversial. Procedure A retrospective cohort design was used to determine if intensive chemoradiotherapy with purged autologous bone marrow rescue (ABMT) and/or 13-cis-retinoic acid (13-cis-RA) improved outcome for patients with high-risk neuroblastoma that was not metastatic to distant sites. We identified 72 patients with INSS Stage 3 neuroblastoma enrolled between 1991 and 1996 on the Phase III CCG 3891 randomized trial. Patients were analyzed on an intent-to-treat basis using a log-rank test. Results The 5-year event-free survival (EFS) and overall survival (OS) rates for patients with Stage 3 neuroblastoma were 55 +/- 6% and 59% +/- 6%, respectively (n=72). Patients randomized to ABMT (n=20) had 5-year EFS of 65% +/- 11% and OS of 65% +/- 11% compared to 41% +/- 11 (p=0.21) and 46% +/- 11% (p=0.23) for patients randomized to CC (n=23), respectively. Patients randomized to 13-cis-RA (n=23) had 5-year EFS of 70% +/- 10% and OS of 78% +/- 9% compared to 63% +/- 12% (p=0.67) and 67% +/- 12% (p=0.55) for those receiving no further therapy (n=16), respectively. Patients randomized to both ABMT and 13-cis-RA (n=6) had a 5-year EFS of 80% ± 11% and OS of 100%. Conclusion Patients with high-risk Stage 3 neuroblastoma have an overall poor prognosis despite aggressive chemoradiotherapy. Further studies are warranted to determine if myeloablative consolidation followed by 13-cis-RA maintenance therapy statistically significantly improves outcome. PMID:18937318

Induction of transplantation tolerance has the potential to allow for allograft acceptance without the need for life-long immunosuppression. Here we describe a novel approach that uses delivery of alloantigen by mature T cells to induce tolerance to fully allogeneic cardiac grafts. Adoptive transfer of mature alloantigen-expressing T cells into myeloablatively conditioned mice results in long-term acceptance of fully allogeneic heart transplants without evidence of chronic rejection. Since myeloablative conditioning is clinically undesirable we further demonstrated that adoptive transfer of mature alloantigen-expressing T cells alone into mice receiving non-myeloablative conditioning resulted in long-term acceptance of fully allogeneic heart allografts with minimal evidence of chronic rejection. Mechanistically, tolerance induction involved both deletion of donor-reactive host T cells and the development of regulatory T cells. Thus, delivery of alloantigen by mature T cells induces tolerance to fully allogeneic organ allografts in non-myeloablatively conditioned recipients, representing a novel approach for tolerance induction in transplantation.

CLL remains incurable with the standard therapy. Allogeneic hematopoietic stem cell transplant may be curative. We examined 50 patients with advanced CLL who underwent allogeneic HCT at the University of Michigan between 1996 and 2006. Twenty-one patients received reduced-intensity conditioning (RIC) and twenty-nine patients received full-intensity conditioning (FIC) consisting of CY, etoposide and BCNU (n=20) or BU and CY (n=9). RIC recipients were older than FIC recipients (median age 54 vs 51, P=0.009). There were no statistically significant differences between groups in terms of the number of earlier therapies or patients with adverse cytogenetics. There were more unrelated donors in the RIC group 62% than in the FIC group 31% (P=0.030). Despite their older age and greater use of URD, the 5-year overall survival (OS) rate was 63% in the RIC group as compared with 18% in the FIC group (P=0.006). The primary cause of inferior survival in the FIC recipients was TRM, which was twice as high at day 100 for the FIC group 27% compared with the RIC group 14% (P=0.005). The relapse rate was 15% regardless with the majority of relapses occurring after day 100. These results suggest a favorable outcome for advanced CLL who undergo a RIC regimen compared with FIC.

Purpose Haploidentical and human leukocyte antigen (HLA)-identical sibling hematopoietic stem transplantation are two main ways used in allogeneic hematopoietic stem cell transplantation (allo-HSCT). In recent years, remarkable progress has been made in haploidentical allo-HSCT (HID-SCT), and some institutions found HID-SCT had similar outcomes as HLA-identical sibling allo-HSCT (ISD-SCT). To clarify if HID-SCT has equal effects to ISD-SCT in hematologic malignancies, we performed this meta-analysis. Methods Relevant articles published prior to February 2017 were searched on PubMed. Two reviewers assessed the quality of the included studies and extracted data independently. Odds ratio (OR) and 95% confidence intervals (CIs) were calculated for statistical analysis. Results Seven studies including 1919 patients were included. The rate of platelet engraftment is significantly lower after HID-SCT versus ISD-SCT while there is no difference in neutrophil engraftment (OR = 2.58, 95% CI = 1.70–3.93, P SCT versus ISD-SCT (OR = 1.88, 95% CI = 1.42–2.49, P SCT group (OR = 0.70, 95% CI = 0.55–0.90, P = 0.005). The incidence rates of overall survival (OS) and disease-free-survival/leukemia-free survival/relapse-free survival (DFS/LFS/RFS) after ISD-SCT are all significantly superior to HID-SCT (OR = 1.32, 95% CI = 1.08–1.62, P = 0.006; OR = 1.25, 95% CI = 1.03–1.52, P = 0.02). There is no significant difference in transplantation related mortality (TRM) rate after HID-SCT and ISD-SCT. Conclusion After myeloablative conditioning, patients receiving ISD-SCT have a faster engraftment, lower acute GVHD and longer life expectancy compared to HID-SCT with GVHD prophylaxis (cyclosporine A, methotrexate, mycophenolate mofetil and antithymoglobulin; CsA + MTX + MMF + ATG). Currently, HID-SCT with GVHD prophylaxis (CsA + MTX + MMF + ATG) may not replace ISD-SCT when HLA-identical sibling donor available. PMID:29381772

We retrospectively evaluated the tolerability and efficacy of fractionated total body irradiation (TBI) (1,200 cGy) and melphalan (MEL) (100-110 mg/m(2)) myeloablative conditioning in 48 patients with nonremission AML (n = 14), ALL (n = 10), NHL (n = 18), and other refractory hematologic malignancies (n = 6) who received allogeneic stem cell transplantation (SCT) between 2002 and 2011. Median age was 48 years (22 to 68); 14 out of 26 leukemia patients (54 %) had circulating blasts at transplant, 20 (50 %) evaluable patients had poor-risk cytogenetics, 12 (25 %) had prior SCT, and 10 (21 %) received stem cells from a mismatch donor. All patients received tacrolimus with or without methotrexate for GVHD prophylaxis. At the time of analysis, 13 patients (27 %) were alive and disease free. Engraftment was complete in all patients. The median time to ANC recovery (>500) was 12 days (range, 6-28). The most common grade III and IV toxicities were mucositis and infections. Eighteen patients (43 %) developed grade II-IV acute GVHD, and eight (26 %) had extensive chronic GVHD. Of 44 evaluable patients for response, 28 (64 %) achieved a complete remission (CR), and seven (15 %) had a partial remission after the transplant. With a median follow-up of 30 months (4 to 124 months) for surviving patients, the cumulative incidence of relapse was 45 % at 1 year, and the probability of overall survival (OS) at 5 years was 22.5 %. Multivariate analysis showed that platelet count (500 IU/L) at SCT were associated with relapse. Age less than 53 years and CR after SCT were associated with better OS. Our data suggest that TBI-MEL can result in CR in two thirds, durable remission in one third, and 5-year survival in about one quarter of patients with nonremission hematologic malignancies. Further studies with TBI-MEL in standard risk transplant patients are warranted.

We evaluated the incidence and risk factors for hypogammaglobulinemia after allogeneic hematopoietic SCT (HSCT) in pediatric patients. Ig levels were measured pre-transplant, every 2 weeks until day 100 and then monthly post SCT in 185 patients undergoing myeloablative HSCT. Median age was 9 years; 142 (77%) had malignant disease and 114 (62%) received stem cells from an unrelated source. Hypogammaglobulinemia (IgG SCT. The cumulative incidence of hypogammaglobulinemia at 1 year was higher among patients who developed acute GVHD (97% vs 54%, PSCT (P<0.001) and development of acute GVHD (P<0.001) were all significantly associated with higher risk of hypogammaglobulinemia post HSCT. We conclude that hypogammaglobulinemia is common, following allogeneic HSCT in pediatric patients, especially in those with malignant diseases, those who receive an unrelated transplant or patients who develop GVHD.

Total body irradiation (TBI) is widely used for conditioning before hematopoietic cell transplantation. Its efficacy and toxicity may depend on many methodological aspects. The goal of the current study was to explore current clinical practice in this field. A questionnaire was sent to all centers collaborating in the European Group for Blood and Marrow Transplantation and included 19 questions regarding various aspects of TBI. A total of 56 centers from 23 countries responded. All centers differed with regard to at least 1 answer. The total maximum dose of TBI used for myeloablative transplantation ranged from 8 grays (Gy) to 14.4 Gy, whereas the dose per fraction was 1.65 Gy to 8 Gy. A total of 16 dose/fractionation modalities were identified. The dose rate ranged from 2.25 centigrays to 37.5 centigrays per minute. The treatment unit was linear accelerator (LINAC) (91%) or cobalt unit (9%). Beams (photons) used for LINAC were reported to range from 6 to 25 megavolts. The most frequent technique used for irradiation was "patient in 1 field," in which 2 fields and 2 patient positions per fraction are used (64%). In 41% of centers, patients were immobilized during TBI. Approximately 93% of centers used in vivo dosimetry with accepted discrepancies between the planned and measured doses of 1.5% to 10%. In 84% of centers, the lungs were shielded during irradiation. The maximum accepted dose for the lungs was 6 Gy to 14.4 Gy. TBI is an extremely heterogeneous treatment modality. The findings of the current study should warrant caution in the interpretation of clinical studies involving TBI. Further investigation is needed to evaluate how methodological differences influence outcome. Efforts to standardize the method should be considered. © 2014 American Cancer Society.

The Genotype of the Donor for the (GTn Polymorphism in the Promoter/Enhancer of FOXP3 Is Associated with the Development of Severe Acute GVHD but Does Not Affect the GVL Effect after Myeloablative HLA-Identical Allogeneic Stem Cell Transplantation.

Directory of Open Access Journals (Sweden)

Víctor Noriega

Full Text Available The FOXP3 gene encodes for a protein (Foxp3 involved in the development and functional activity of regulatory T cells (CD4+/CD25+/Foxp3+, which exert regulatory and suppressive roles over the immune system. After allogeneic stem cell transplantation, regulatory T cells are known to mitigate graft versus host disease while probably maintaining a graft versus leukemia effect. Short alleles (≤(GT15 for the (GTn polymorphism in the promoter/enhancer of FOXP3 are associated with a higher expression of FOXP3, and hypothetically with an increase of regulatory T cell activity. This polymorphism has been related to the development of auto- or alloimmune conditions including type 1 diabetes or graft rejection in renal transplant recipients. However, its impact in the allo-transplant setting has not been analyzed. In the present study, which includes 252 myeloablative HLA-identical allo-transplants, multivariate analysis revealed a lower incidence of grade III-IV acute graft versus host disease (GVHD in patients transplanted from donors harboring short alleles (OR = 0.26, CI 0.08-0.82, p = 0.021; without affecting chronic GVHD or graft versus leukemia effect, since cumulative incidence of relapse, event free survival and overall survival rates are similar in both groups of patients.

To analyze coping strategies used by children with cancer undergoing chemotherapy during hospitalization. This was an exploratory study to analyze qualitative data using an inductive thematic analysis. Semistructured interviews using puppets were conducted with 10 children with cancer, between 7 and 12 years old, who were hospitalized and undergoing chemotherapy. The coping strategies to deal with chemotherapy were: understanding the need for chemotherapy; finding relief for the chemotherapy's side effects and pain; seeking pleasure in nourishment; engaging in entertaining activities and having fun; keeping the hope of cure alive; and finding support in religion. Children with cancer undergoing chemotherapy need to cope with hospitalizations, pain, medication side effects, idle time, and uncertainty regarding the success of treatment. These challenges motivated children to develop their own coping strategies, which were effective while undergoing chemotherapy. By gaining knowledge and further understanding about valid coping strategies during chemotherapy treatment, health professionals can mobilize personal and material resources from the children, health teams, and institutions aiming to potentiate the use of these strategies to make treatments the least traumatic. © 2015 Sigma Theta Tau International.

Objectives This study aimed to review general anaesthesia protocols for patients undergoing electroconvulsive therapy (ECT) at a tertiary care hospital in Oman, particularly with regards to clinical profile, potential drug interactions and patient outcomes. Methods This retrospective study took place at the Sultan Qaboos University Hospital (SQUH), Muscat, Oman. The electronic medical records of patients undergoing ECT at SQUH between January 2010 and December 2014 were reviewed for demographic characteristics and therapy details. Results A total of 504 modified ECT sessions were performed on 57 patients during the study period. All of the patients underwent a uniform general anaesthetic regimen consisting of propofol and succinylcholine; however, they received different doses between sessions, as determined by the treating anaesthesiologist. Variations in drug doses between sessions in the same patient could not be attributed to any particular factor. Self-limiting tachycardia and hypertension were periprocedural complications noted among all patients. One patient developed aspiration pneumonitis (1.8%). Conclusion All patients undergoing ECT received a general anaesthetic regimen including propofol and succinylcholine. However, the interplay of anaesthetic drugs with ECT efficacy could not be established due to a lack of comprehensive data, particularly with respect to seizure duration. In addition, the impact of concurrent antipsychotic therapy on anaesthetic dose and subsequent complications could not be determined. PMID:28417028

Hypovitaminosis D in patients undergoing kidney transplant: the importance of sunlight exposure

Directory of Open Access Journals (Sweden)

Cristiane F. Vilarta

Full Text Available OBJECTIVES: Recent studies have shown a high prevalence of hypovitaminosis D, defined as a serum 25-hydroxyvitamin D level less than 30 ng/ml, in both healthy populations and patients with chronic kidney disease. Patients undergoing kidney transplant are at an increased risk of skin cancer and are advised to avoid sunlight exposure. Therefore, these patients might share two major risk factors for hypovitaminosis D: chronic kidney disease and low sunlight exposure. This paper describes the prevalence and clinical characteristics of hypovitaminosis D among patients undergoing kidney transplant. METHODS: We evaluated 25-hydroxyvitamin D serum levels in a representative sample of patients undergoing kidney transplant. We sought to determine the prevalence of hypovitaminosis D, compare these patients with a control group, and identify factors associated with hypovitaminosis D (e.g., sunlight exposure and dietary habits. RESULTS: Hypovitaminosis D was found in 79% of patients undergoing kidney transplant, and the major associated factor was low sunlight exposure. These patients had higher creatinine and intact parathyroid hormone serum levels, with 25-hydroxyvitamin D being inversely correlated with intact parathyroid hormone serum levels. Compared with the control group, patients undergoing kidney transplant presented a higher prevalence of 25-hydroxyvitamin D deficiency and lower serum calcium, phosphate and albumin but higher creatinine and intact parathyroid hormone levels. CONCLUSIONS: Our results confirmed the high prevalence of hypovitaminosis D in patients undergoing kidney transplant. Therapeutic strategies such as moderate sunlight exposure and vitamin D supplementation should be seriously considered for this population.

Management of coagulation in neurosurgical procedures is challenging. In this contest, it is imperative to avoid further intracranial bleeding. Perioperative bleeding can be associated with a number of factors, including anticoagulant drugs and coagulation status but is also linked to the characteristic and the site of the intracranial disorder. The aim of this review will be to focus primarily on the new evidence regarding the management of coagulation in patients undergoing craniotomy for neurosurgical procedures. Antihemostatic and anticoagulant drugs have shown to be associated with perioperative bleeding. On the other hand, an increased risk of venous thromboembolism and hypercoagulative state after elective and emergency neurosurgery, in particular after brain tumor surgery, has been described in several patients. To balance the risk between thrombosis and bleeding, it is important to be familiar with the perioperative changes in coagulation and with the recent management guidelines for anticoagulated patients undergoing neurosurgical procedures, in particular for those taking new direct anticoagulants. We have considered the current clinical trials and literature regarding both safety and efficacy of deep venous thrombosis prophylaxis in the neurosurgical population. These were mainly trials concerning both elective surgical and intensive care patients with a poor grade intracranial bleed or multiple traumas with an associated severe traumatic brain injury (TBI). Coagulation management remains a major issue in patients undergoing neurosurgical procedures. However, in this field of research, literature quality is poor and further studies are necessary to identify the best strategies to minimize risks in this group of patients.

To characterize the profile and speech characteristics of patients undergoing primary palatoplasty in a Brazilian university hospital, considering the time of intervention (early, before two years of age; late, after two years of age). Participants were 97 patients of both genders with cleft palate and/or cleft and lip palate, assigned to the Speech-language Pathology Department, who had been submitted to primary palatoplasty and presented no prior history of speech-language therapy. Patients were divided into two groups: early intervention group (EIG) - 43 patients undergoing primary palatoplasty before 2 years of age and late intervention group (LIG) - 54 patients undergoing primary palatoplasty after 2 years of age. All patients underwent speech-language pathology assessment. The following parameters were assessed: resonance classification, presence of nasal turbulence, presence of weak intraoral air pressure, presence of audible nasal air emission, speech understandability, and compensatory articulation disorder (CAD). At statistical significance level of 5% (p≤0.05), no significant difference was observed between the groups in the following parameters: resonance classification (p=0.067); level of hypernasality (p=0.113), presence of nasal turbulence (p=0.179); presence of weak intraoral air pressure (p=0.152); presence of nasal air emission (p=0.369), and speech understandability (p=0.113). The groups differed with respect to presence of compensatory articulation disorders (p=0.020), with the LIG presenting higher occurrence of altered phonemes. It was possible to assess the general profile and speech characteristics of the study participants. Patients submitted to early primary palatoplasty present better speech profile.

Background Of the 1.5 million people diagnosed with pleural effusion annually in the U.S., approximately 178,000 undergo thoracentesis. While it is known that malignant pleural effusion portends a poor prognosis, mortality of patients with nonmalignant effusions has not been well studied. Methods This prospective cohort study evaluated 308 patients undergoing thoracentesis. Chart review was performed to obtain baseline characteristics. The etiology of the effusions was determined using standardized criteria. Mortality was determined at 30-days and 1-year. Results 247 unilateral and 61 bilateral thoracenteses were performed. Malignant effusion had the highest 30-day (37%) and 1 year (77%) mortality. There was substantial patient 30-day and 1-year mortality with effusions due to multiple benign etiologies (29% and 55%), CHF (22% and 53%), and renal failure (14% and 57%). Patients with bilateral pleural effusion, relative to unilateral, were associated with higher risk of death at 30 days and 1 year (17% versus 47%; HR 2.58 CI [1.44–4.63] and 36% versus 69%; HR 2.32 CI [1.55–3.48]). Conclusions Patients undergoing thoracentesis for pleural effusion have high short and long-term mortality. Patients with malignant effusion had the highest mortality followed by multiple benign etiologies, CHF and renal failure. Bilateral pleural effusion is distinctly associated with high mortality.

Stress modeling in colloidal dispersions undergoing non-viscometric flows

Science.gov (United States)

Dolata, Benjamin; Zia, Roseanna

2017-11-01

We present a theoretical study of the stress tensor for a colloidal dispersion undergoing non-viscometric flow. In such flows, the non-homogeneous suspension stress depends on not only the local average total stresslet-the sum of symmetric first moments of both the hydrodynamic traction and the interparticle force-but also on the average quadrupole, octupole, and higher-order moments. To compute the average moments, we formulate a six dimensional Smoluchowski equation governing the microstructural evolution of a suspension in an arbitrary fluid velocity field. Under the conditions of rheologically slow flow, where the Brownian relaxation of the particles is much faster than the spatiotemporal evolution of the flow, the Smoluchowski equation permits asymptotic solution, revealing a suspension stress that follows a second-order fluid constitutive model. We obtain a reciprocal theorem and utilize it to show that all constitutive parameters of the second-order fluid model may be obtained from two simpler linear-response problems: a suspension undergoing simple shear and a suspension undergoing isotropic expansion. The consequences of relaxing the assumption of rheologically slow flow, including the appearance of memory and microcontinuum behaviors, are discussed.

The International Commission of Radiology recommends a pregnancy screening test to all female patients of childbearing age who will undergo a radiological study. Radiation is known to be teratogenic and its effect is cumulative. The teratogenic potential starts at doses close to those used during these procedures. The prevalence of positive pregnancy tests in patients undergoing electrophysiological studies and/or catheter ablation in our midst is unknown. To evaluate the prevalence of positive pregnancy tests in female patients referred for electrophysiological study and/or radiofrequency ablation. Cross-sectional study analyzing 2,966 patients undergoing electrophysiological study and/or catheter ablation, from June 1997 to February 2013, in the Institute of Cardiology of Rio Grande do Sul. A total of 1490 procedures were performed in women, of whom 769 were of childbearing age. All patients were screened with a pregnancy test on the day before the procedure. Three patients tested positive, and were therefore unable to undergo the procedure. The prevalence observed was 3.9 cases per 1,000 women of childbearing age. Because of their safety and low cost, pregnancy screening tests are indicated for all women of childbearing age undergoing radiological studies, since the degree of ionizing radiation needed for these procedures is very close to the threshold for teratogenicity, especially in the first trimester, when the signs of pregnancy are not evident.

(131) I-metaiodobenzylguanidine (MIBG) produces a 37% response rate in relapsed/refractory neuroblastoma, and could be used to improve remission status prior to myeloablative chemotherapy with autologous stem cell transplant (ASCT). The purpose of our report was to evaluate safety and response with MIBG therapy followed by myeloablative busulfan and melphalan (BuMel) with ASCT in patients with refractory neuroblastoma. Retrospective chart review was done on patients treated with MIBG (18 mCi/kg) on Day 1 and ASCT on day 14. Six to eight weeks after MIBG, patients without progressive disease received IV busulfan on days -6 to -2 (target Css 700-900), melphalan (140 mg/m2 IV) on day -1, and ASCT on Day 0. Response and toxicity were evaluated after MIBG and again after myeloablative therapy. Eight patients completed MIBG/ASCT followed by BuMel/ASCT. MIBG was well tolerated, with grade 3 or 4 non-hematologic toxicity limited to one patient with sepsis. Grade 3 mucositis occurred in six patients after BuMel/ASCT. One patient developed sinusoidal obstructive syndrome (SOS) and died 50 days post-ASCT following myeloablative conditioning. All patients engrafted neutrophils (median 16.5 days) and platelets (median 32 days) after BuMel, excluding the patient with SOS. After all therapy, there were three complete, two partial, and one minor response in seven evaluable patients. MIBG at doses up to 18 mCi/kg can be safely administered 6 weeks prior to a BuMel consolidative regimen for refractory neuroblastoma. Preceding MIBG did not impair engraftment following BuMel. This regimen is being further evaluated in a Children's Oncology Group (COG) trial. Copyright © 2012 Wiley Periodicals, Inc.

An increasing number of women are undergoing labiaplasty procedures; however, very little is known about the psychological factors that motivate women to seek out this procedure. To investigate the factors that influence women's decisions to undergo labiaplasty. Women seeking to undergo labiaplasty (n = 35) were compared with women who were not (n = 30). Standardized measures were employed to assess the patients' media exposure (television, the Internet, advertising, pornography), relationship quality, and psychological well-being. Women's motivations for deciding to undergo a labiaplasty procedure were characterized as "appearance," "functional," "sexual," or "psychological" motivations, with concerns about the labia's appearance being the most commonly reported motivation. Correspondingly, women seeking labiaplasty were significantly less satisfied with the appearance of their genitals than the comparison group (P media exposure and relationship status as important factors that influence women's decisions to undergo labiaplasty. 3 Risk. © 2016 The American Society for Aesthetic Plastic Surgery, Inc.

Full Text Available Background: The advanced era of technological development in child health care has resulted in more pediatric procedures being performed in various settings. Millions of children undergo surgery every year which is a stressful event. Many nonpharmacological strategies are being used to manage the preoperative fear and anxiety in children. The current study aims to assess the effectiveness of multimodal preoperative preparation program (MPPP on children undergoing surgery in terms of its effect on the psychophysiological parameters. Objective: The aim of this study is to assess the effectiveness of MPPP on the psychophysiological parameters of children undergoing surgery. Materials and Methods: A quasi-experimental study was conducted in a selected multi-specialty hospital. Using the purposive sampling technique, a total of 110 children aged 8–12 years were assigned to nonintervention (n = 55 and intervention (n = 55 groups, respectively. The MPPP was administered to the intervention group. The children in the nonintervention group received the routine preoperative care. Child's fear and anxiety was assessed on admission, prior to shifting the child to operation theater (OT, 24 and 48 h after surgery, whereas child's pulse, respiration, blood pressure (BP, and oxygen saturation was assessed on admission, prior to shifting the child to OT, 6, 12, 24, and 48 h after surgery and pain was assessed at 24 and 48 h after surgery. Results: The mean fear and anxiety scores of children were significantly lower in the intervention group than that of nonintervention group (P 0.05. This study also found that there is a significant association between the psychophysiological parameters of children with the selected demographic variables (P < 0.05. A positive correlation was found between the psychological and physiological parameters of children undergoing surgery. Conclusion: The MPPP is effective on psychophysiological parameters of children undergoing

To compare outcomes for women undergoing two in vitro fertilization (IVF) pregnancies with singletons and women undergoing one IVF twin pregnancy. The concept of single-embryo transfer in IVF has reduced the risks of both maternal and neonatal complications, but there is still a discussion of whether or not twins are a desired outcome of IVF. Registry study. Not applicable. All reported twins after IVF with double-embryo transfer (n = 1,982) and their mothers (n = 991) and all mothers (n = 921) who gave birth to two IVF singletons (n = 1,842). None. Maternal and neonatal outcomes including severe neonatal morbidity. Preterm birth, very preterm birth, low birth weight, very low birth weight, and small for gestational age were dramatically increased for IVF twins compared with two IVF singletons with the same mother, with adjusted odds ratios from 4 to 16. Significantly higher rates of respiratory complications, sepsis, and jaundice were detected among the IVF twins. Significantly higher rates of preeclampsia, preterm premature rupture of the membranes, and cesarean section were observed for IVF twin pregnancies. The neonatal and maternal outcomes were dramatically better for women undergoing two IVF singleton pregnancies compared with one IVF twin pregnancy after double-embryo transfer. These results support single-embryo transfer to minimize the risks associated with twin pregnancies. Copyright © 2013 American Society for Reproductive Medicine. Published by Elsevier Inc.

The aim of this study was to prospectively assess women's pain during rigid and flexible diagnostic cystoscopy and afterwards during a one-week follow-up. Prospective, multi-institutional trial analyzing numeric rating scales (NRS) of women undergoing diagnostic cystoscopy. Pain categories: no (0 points), mild (1-3), moderate (4-6) and severe pain (7-10). Assessing of pain before, during cystoscopy, and at day 1, 4 and 7 of follow-up. A total of 150 women undergoing rigid (N.=85) or flexible (N.=65) diagnostic cystoscopy were analyzed. Women undergoing flexible cystoscopy were more frequently pain-free (64.6% vs. 40%, P=0.003) and experienced mild pain less frequently (27.7% vs. 52.9% vs. P=0.002). No significant differences were noted among moderate (6.2% vs. 5.9%, P=0.95) and severe pain (1.5% vs. 1.2%, P=0.85). Patients undergoing their first (P=0.14) and repeat cystoscopy (P=0.08) had similar pain perception. In multivariate logistic regression analyses, women undergoing flexible cystoscopy had a 2.6 increased chance of being pain-free (OR=2.6, CI: 1.28-5.11, P=0.08) and their odds of experiencing mild pain were significantly lower (OR=0.34, CI: 0.17-0.71, P=0.004). The likelihood of experiencing moderate (OR=1.1, CI: 0.28- 4.4, P=0.83) or severe pain (OR=2.42, CI: 0.11-51.79, P=0.57) differed insignificantly. Rigid and flexible cystoscopies were well-tolerated by most women. However, flexible cystoscopy was associated with a higher likelihood of being pain-free and lower chances of experiencing mild pain. Patients' previous experience with cystoscopy did not influence pain perception.

To determine if dogs that undergo laparotomy for cholecystectomy suffer from a greater number or magnitude of perianesthetic complications, including hypotension, hypothermia, longer recovery time, and lower survival rate, than dogs that undergo laparotomy for hepatic surgery without cholecystectomy. Retrospective cohort study. One hundred and three dogs, anesthetised between January 2007 and October 2011. The variables collected from the medical record included age, weight, gender, surgical procedure, pre-operative bloodwork, American Society of Anesthesiologists (ASA) status, emergency status, total bilirubin concentration, anesthetic agents administered, body temperature nadir, final body temperature, hypotension, duration of hypotension, blood pressure nadir, intraoperative drugs, anesthesia duration, surgery duration, time to extubation, final diagnosis, days spent in the intensive care unit (ICU), total bill, survival to discharge, and survival to follow-up. No significant difference in body temperature nadir, final temperature, presence of hypotension, duration of hypotension, blood pressure nadir, the use of inotropes, or final outcome was found between dogs undergoing cholecystectomy and dogs undergoing exploratory laparotomy for other hepatic disease. Dogs that had cholecystectomy had longer anesthesia durations and longer surgery durations than dogs that did not have cholecystectomy. No significant differences existed for temperature nadir (34.8 versus 35.3°C; non-cholecystectomy versus cholecystectomy), final temperature (35.6 versus 35.9°C), time to extubation (30 versus 49 minutes), duration of hypotension (27 versus 21 minutes), or MAP nadir (56 versus 55 mmHg). Hypotension occurred in 66% and 74% and inotropes were used in 64% and 53%, for non-cholecystectomy and cholecystectomy patients, respectively. Dogs that underwent cholecystectomies did not suffer a greater number of anesthesia complications than did dogs undergoing hepatic surgery without

Cardiac disease frequently occurs in children with chronic kidney disease (CKD) undergoing dialysis (DI), but it is not well studied in patients undergoing conservative treatment (CT). The aim of our study was to use echocardiography to analyze and compare the cardiac involvement of children with CKD undergoing DI or CT. Seventy-one children with CKD were included; 41 undergoing DI and 30 undergoing CT. There were 33 controls. Measurements of arterial pressure and structural and functional echocardiographic variables were obtained; the children were followed up for 18 months. Tests of comparison and multiple regression were used; significant if P < 0.05. Arterial hypertension (AH) was present in 37 of 71 (52%) children with CKD: 27 (65.8%) in DI and 10 (33.3%) in CT (X2 = 8.7; P = 0.003). An abnormal left ventricular geometric pattern was present in 37/41 (90.3%) undergoing DI, 33 had left ventricular hypertrophy (LVH), and in 14/30 (46.7%) undergoing CT, 5 had LVH. Ejection fraction was normal in all groups; diastolic function alteration (DFA) occurred in 28/41 (68.3%) children on DI and in 10/30 (33.3%) on CT (X2 = 9.2; P = 0.002). For children with CKD, DI (P = 0.002) and hypertension (P = 0.04) were associated with LVH; among those on DI, only AH was associated with LVH (P = 0.02). During the follow-up, 18 (43.9%) children undergoing DI had at least one cardiovascular event. Children with CKD undergoing CT had less cardiac involvement than those undergoing DI. LVH was associated with DI and AH in all children with CKD and with AH in those on DI.

To analyze perceived health status and other health-related indicators in the adult population in Granada (Spain) undergoing an eviction process from their homes, whether rented or owned, in comparison with health indicators in the general adult population in Andalusia. A cross-sectional survey was administered by trained staff. The survey included instruments from the Andalusian Health Survey 2011 for measuring variables related to physical and mental health, as well as health-related habits. We compared the results with those obtained from the Andalusian general population through the Andalusian Health Survey. A bivariate analysis using the χ2 test and a multivariate logistic regression analysis were conducted. We obtained a total sample of 205 people in the process of eviction. A total of 59.5% (n=122) were women, and 40.5% (n=83) were men. Participants were more likely to have poor health (odds ratio [OR]: 12.63, 95% confidence interval [95%CI]: 8.74-18.27), have cardiovascular diseases (OR: 3.08; 95%CI: 1.54- 6.16), or to smoke (OR: 1.68; 95% CI: 1.21-2.33) compared with the Andalusian general population. Most of the health indicators analyzed showed a worse outcome for women undergoing an eviction process. Our results suggest that, in the current context of economic crisis, people undergoing a process of eviction in Granada and its metropolitan area show poorer health than the Andalusian general population. Further research is needed on health and evictions from different methodological approaches, for a better understanding of the topic. Copyright © 2015 SESPAS. Published by Elsevier Espana.

Darisi, Tanya; Thorne, Sarah; Iacobelli, Carolyn

2005-09-01

Research was conducted to gain insight into potential clients' decisions to undergo plastic surgery, their perception of benefits and risks, their judgment of outcomes, and their selection of a plastic surgeon. Semistructured, open-ended interviews were conducted with 60 people who expressed interest in plastic surgery. Qualitative analysis revealed their "mental models" regarding influences on their decision to undergo plastic surgery and their choice of a surgeon. Interview results were used to design a Web-based survey in which 644 individuals considering plastic surgery responded. The desire for change was the most direct motivator to undergo plastic surgery. Improvements to physical well-being were related to emotional and social benefits. When prompted about risks, participants mentioned physical, emotional, and social risks. Surgeon selection was a critical influence on decisions to undergo plastic surgery. Participants gave considerable weight to personal consultation and believed that finding the "right" plastic surgeon would minimize potential risks. Findings from the Web-based survey were similar to the mental models interviews in terms of benefit ratings but differed in risk ratings and surgeon selection criteria. The mental models interviews revealed that interview participants were thoughtful about their decision to undergo plastic surgery and focused on finding the right plastic surgeon.

The aim of this study was to evaluate the changes in salivary gland function in patients with chronic renal failure (CRF) undergoing hemodialysis. The group consisted of 23 patients with CRF (13 female, 10 male; mean age: 40±13 yr) and 14 healthy control subjects (mean age: 40±13 yr). All underwent dynamic salivary gland scintigraphy with gustatory stimulation. After intravenous administration of 99m Tc pertechnetate, first, perfusion images at 2 seconds per frame were acquired for 1 minute, then dynamic images at 1 minute per frame were acquired for 45 minutes. At 30 minutes after injection , 10 ml lemon juice was given for 15 minutes as a gustatory stimulus. We obtained time-activity curves derived from regions of interest centered over the four major salivary glands. The following functional indices were calculated for each gland: the time of maximum radioactivity (T max ) for the prestimulated period, the time of minimum radioactivity (T min ), as an indicator of velocity of secretion after stimulation, and the Lem E 5 % value as an indicator of the secretion function. When the patients with CRF undergoing hemodialysis were compared to the controls, there were statistically significant differences in T max , T min and Lem E 5 % values for bilateral parotid glands, and T min values for bilateral submandibular glands (p max and Lem E 5 % values for bilateral submandibular glands. There were also significant differences in T max and Lem E 5 % values for bilateral parotid glands between mild oral problems and severe oral problems in patients with CRF (undergoing hemodialysis). In this study, prolonged T max and T min values, and decreased Lem E 5 % values for parotid glands and prolonged T min values for submandibular glands on salivary scintigraphy pointed out decreased parenchymatous and excretory function in patients with CRF undergoing hemodialysis.

Sterilization is most widely used fertility regulation method in Nepal. However, prevalence of uptake of female sterilization in central hilly region is less than the national average. The objective of the study was to explore the number and factors related to intention of married women to undergo female sterilization in rural Kathmandu which lies within central hilly region. This is a community based cross-sectional survey research conducted in rural area of Kathmandu valley. Two hundred and forty currently married women with at least one child of any age were interviewed using a structured pre-tested questionnaire. More than four-fifth of the respondents intended to undergo sterilization. Almost two-third of them wanted to limit their family size by taking this option. More than one-third of women not-intending to undergo sterilization feared weakness after sterilization. Age of the respondents, duration of marriage, and number of living children were significantly associated with intention to undergo sterilization. 15-24 years age group were six times more likely to have the intention for sterilization (OR 6.79, CI 2.28-20.19) compared to age 35 years and above group. Mothers with less than 3 living children are about three times more likely to have the intention to undergo sterilization (OR 2.87, CI 1.3-6.33) compared to women with more than 2 living children. Women married for 6 to 10 years were three times more likely to have the intention (OR 3.0, CI 1.09-8.27). However, gender of the living children was not associated with intention to undergo sterilization. There were significant numbers of women intending to undergo sterilization. Age of the mother, number of living children and the duration of marriage were found to be significantly influencing the intention to undergo sterilization. However, as intention refers to future plan, the respondents' intention may change over time. The national family planning program also needs to identify the key factors in

AIM: To investigate the effect of pain relief after infusion of ropivacaine at port sites at the end of surgery. METHODS: From October 2006 to September 2007, 72 patients undergoing laparoscopic cholecystectomy (LC) were randomized into two groups of 36 patients. One group received ropivacaine infusion at the port sites at the end of LC and the other received normal saline. A visual analog scale was used to assess postoperative pain when the patient awakened in the operating room, 6 and 24 h after surgery, and before discharge. The amount of analgesics use was also recorded. The demographics, laboratory data, hospital stay, and perioperative complications were compared between the two groups. RESULTS: There was no difference between the two groups preoperatively in terms of demographic and laboratory data. After surgery, similar operation time, blood loss, and no postoperative morbidity and mortality were observed in the two groups. However, a significantly lower pain score was observed in the patients undergoing LC with local anesthesia infusion at 1 h after LC and at discharge. Regarding analgesic use, the amount of meperidine used 1 h after LC and the total used during admission were lower in patients undergoing LC with local anesthesia infusion. This group also had a shorter hospital stay. CONCLUSION: Local anesthesia with ropivacaine at the port site in LC patients significantly decreased postoperative pain immediately. This explains the lower meperidine use and earlier discharge for these patients. PMID:19452582

To evaluate predictors of allogenic blood transfusion requirements in patients undergoing minimal invasive oesophagectomy at a tertiary high volume centre for oesophago-gastric surgery. Retrospective analysis of all patients undergoing minimal access oesophagectomy in our department between January 2010 and December 2011. Patients were divided into two groups depending on whether they required a blood transfusion at any time during their index admission. Factors that have been shown to influence perioperative blood transfusion requirements in major surgery were included in the analysis. Binary logistic regression analysis was performed to determine the impact of patient and perioperative characteristics on transfusion requirements during the index admission. A total of 80 patients underwent minimal access oesophagectomy, of which 61 patients had a laparoscopic assisted oesophagectomy and 19 patients had a minimal invasive oesophagectomy. Perioperative blood transfusion was required in 28 patients at any time during hospital admission. On binary logistic regression analysis, a lower preoperative haemoglobin concentration (p blood transfusion requirements. It has been reported that requirement for blood transfusion can affect long-term outcomes in oesophageal cancer resection. Two factors which could be addressed preoperatively; haemoglobin concentration and type of oesophageal resection, may be valuable in predicting blood transfusions in patients undergoing minimally invasive oesophagectomy. Our analysis revealed that preoperative haemoglobin concentration, occurrence of significant complications and type of minimal access oesophagectomy predicted blood transfusion requirements in the patient population examined.

Retrospective database analysis. To investigate incidence, comorbidities, and impact on health care resources of Clostridium difficile infection after lumbar spine surgery. C. difficile colitis is reportedly increasing in hospitalized patients and can have a negative impact on patient outcomes. No data exist on estimates of C. difficile infection rates and its consequences on patient outcomes and health care resources among patients undergoing lumbar spine surgery. The Nationwide Inpatient Sample was examined from 2002 to 2011. Patients were included for study based on International Classification of Diseases, Ninth Revision, Clinical Modification, procedural codes for lumbar spine surgery for degenerative diagnoses. Baseline patient characteristics were determined and multivariable analyses assessed factors associated with increased incidence of C. difficile and risk of mortality. The incidence of C. difficile infection in patients undergoing lumbar spine surgery is 0.11%. At baseline, patients infected with C. difficile were significantly older (65.4 yr vs. 58.9 yr, Pinfection. Small hospital size was associated with decreased odds (odds ratio [OR], 0.5; Pinfection. Uninsured (OR, 1.62; Pinfection. C. difficile increased hospital length of stay by 8 days (Pdifficile infection after lumbar spine surgery carries a 36.4-fold increase in mortality and costs approximately $10,658,646 per year to manage. These data suggest that great care should be taken to avoid C. difficile colitis in patients undergoing lumbar spine surgery because it is associated with longer hospital stays, greater overall costs, and increased inpatient mortality. 3.

Stevens Johnson Syndrome in a patient undergoing gynaecological brachytherapy: An association or an incident?

International Nuclear Information System (INIS)

Ferreira, M. R.; Amado, A.; Jorge, M.; Grillo, I. M.

2011-01-01

Background: Stevens Johnson Syndrome and Erythema Multiforme are hypersensitivity skin reactions generally arising in the context of multiple causes. Radiation therapy is considered to be one of these causes, although most reports are hindered by concomitant medications. Aim: The aim of this paper was to present a case of Stevens Johnson Syndrome arising in a patient undergoing gynaecological brachytherapy with an unusual presentation. Case:We describe a case of a 56-year-old woman with endometrial cancer undergoing adjuvant gynaecological radiotherapy. While undergoing a gynaecological brachytherapy boost, she developed bilateral conjunctivitis that progressed to oral mucositis and pruritic erythema with sloughing of the skin on her arms and legs but not the torso or irradiated fields (namely the vaginal mucosa). Conclusion: This case illustrates the association of RT/SJS; however, it also raises the question of patients undergoing RT being more susceptible to SJS as opposed to a direct cause of the disease.

Utility of an Australasian registry for children undergoing radiation treatment

International Nuclear Information System (INIS)

Ahern, Verity

2014-01-01

The aim of this study was to evaluate the utility of an Australasian registry ('the Registry') for children undergoing radiation treatment (RT). Children under the age of 16years who received a course of radiation between January 1997 and December 2010 and were enrolled on the Registry form the subjects of this study. A total of 2232 courses of RT were delivered, predominantly with radical intent (87%). Registrations fluctuated over time, but around one-half of children diagnosed with cancer undergo a course of RT. The most prevalent age range at time of RT was 10–15years, and the most common diagnoses were central nervous system tumours (34%) and acute lymphoblastic leukaemia (20%). The Registry provides a reflection of the patterns of care of children undergoing RT in Australia and a mechanism for determining the resources necessary to manage children by RT (human, facilities and emerging technologies, such as proton therapy). It lacks the detail to provide information on radiotherapy quality and disease outcomes which should be the subject of separate audit studies. The utility of the Registry has been hampered by its voluntary nature and varying needs for consent. Completion of registry forms is a logical requirement for inclusion in the definition of a subspecialist in paediatric radiation oncology.

To investigate the effects of different tilt angles of head-up tilt test (HUTT) and different responses to HUTT on the psychological fear in children undergoing the test. HUTT was performed on children with unexplained syncope or pre-syncope (107 cases: 52 males and 55 females), aged 5.5-17.8 years (mean 12.0±2.8 years). All subjects were randomly assigned to undergo HUTT at an angle of 60°, 70° or 80°; the negative cases underwent sublingual nitroglycerin-provocation HUTT at the same tilt angle. The Wong-Baker Faces Pain Rating Scale was used for self-assessment of psychological fear in subjects during HUTT at the end point of the test. The positive rate, hemodynamic changes and distribution of response types showed no significant differences between children at tilt angles of 60°, 70° and 80° (P>0.05). The greater the tilt angle, the higher the degree of psychological fear in children undergoing the test, but there were no significant differences between them (P>0.05). The degree of psychological fear in children who showed a positive response to HUTT (n=76) was significantly higher than that in children who showed a negative response (n=31) (Pfear in children undergoing the test, and the degree of psychological fear increases in children tested at tilt angles from 60° to 80°, but the differences have no statistical significance. A positive response to HUTT can significantly increase the psychological fear in children.

Diverticular disease of the colon is frequent in clinical practice, and a large number of patients each year undergo surgical procedures worldwide for their symptoms. Thus, there is a need for better knowledge of the basic pathophysiologic mechanisms of this disease entity. Because patients with colonic diverticular disease have been shown to display abnormalities of the enteric nervous system, we assessed the frequency of myenteric plexitis (i.e. the infiltration of myenteric ganglions by inflammatory cells) in patients undergoing surgery for this condition. We analyzed archival resection samples from the proximal resection margins of 165 patients undergoing left hemicolectomy (60 emergency and 105 elective surgeries) for colonic diverticulitis, by histology and immunochemistry. Overall, plexitis was present in almost 40% of patients. It was subdivided into an eosinophilic (48%) and a lymphocytic (52%) subtype. Plexitis was more frequent in younger patients; and it was more frequent in those undergoing emergency surgery (50%), compared to elective (28%) surgery (p = 0.007). All the severe cases of plexitis displayed the lymphocytic subtype. In conclusion, myenteric plexitis is frequent in patients with colonic diverticular disease needing surgery, and it might be implicated in the pathogenesis of the disease.

2017-10-01

Because the islets of Langerhans are more prevalent in the body and tail of the pancreas, distal pancreatectomy (DP) is believed to increase the likelihood of developing new onset diabetes mellitus (NODM). To determine whether the development of postoperative diabetes was more prevalent in patients undergoing DP or Whipple procedure, 472 patients undergoing either a DP (n = 122) or Whipple (n = 350), regardless of underlying pathology, were analyzed at one month postoperatively. Insulin or oral hypoglycemic requirements were assessed and patients were stratified into preoperative diabetic status: NODM or preexisting diabetes. A retrospective chart review of the 472 patients between 1996 and 2014 showed that the total rate of NODM after Whipple procedure was 43 per cent, which was not different from patients undergoing DP (45%). The incidence of preoperative diabetes was 12 per cent in patients undergoing the Whipple procedure and 17 per cent in the DP cohort. Thus, the overall incidence of diabetes after Whipple procedure was 54 and 49 per cent in the DP group. The development of diabetes was unrelated to the type of resection performed. Age more than 65 and Caucasian ethnicity were associated with postoperative diabetes regardless of the type of resection performed.

Full Text Available Background: Primary hyperaparathyroidism (pHPT is often accompanied by underlying thyroid pathology that can confound preoperative parathyroid localization studies and complicate intra-operative decision making. The aim of this study was to examine the utility of preoperative thyroid ultrasonography (US in patients prior to undergoing parathyroidectomy for pHPT.Methods: An Institutional Review Board approved prospective study was undertaken from January 2005 through July 2008. All patients with pHPT meeting inclusion criteria (n=94 underwent preoperative thyroid ultrasound in addition to standard 99mTc-sestamibi scintigraphy for parathyroid localization. Demographics, operative management and final pathology were examined in all cases.Results: Fifty-four of the 94 patients (57% were noted to have a thyroid nodule on preoperative US, of which 30 (56% underwent further examination with fine needle aspiration biopsy. Alteration of the operative plan attributable to underlying thyroid pathology occurred in 16 patients (17%, with patients undergoing either total thyroidectomy (n=9 or thyroid lobectomy (n=7. Thyroid cancer was noted in 33% of patients undergoing thyroid resection, and 6% of all patients with HPT.Conclusions: The routine utilization of preoperative thyroid ultrasound in patients prior to undergoing parathyroid surgery for pHPT is indicated. The added information from this non-invasive modality facilitates timely management of co-incidental, and sometimes malignant, thyroid pathology.

Obesity continues to be an increasing global health issue contributing to the complexity of chemotherapy dosing in the field of SCT. Investigation into the optimal dosing weight used to calculate chemotherapy doses in obese patients undergoing SCT is limited and inconclusive. Our single-center, retrospective study compared safety and efficacy outcomes by body mass index (BMI) for 476 adult lymphoma patients who underwent auto-SCT with a myeloablative chemotherapeutic regimen of BU, CY and etoposide dosed using adjusted body weight. Three weight groups categorized based on BMI were defined: normal/underweight ⩽24.9 kg/m(2), overweight 25-29.9 kg/m(2) and obese ⩾30 kg/m(2). Severity of mucositis, incidence of secondary malignancy, incidence of bacteremia and median hospital length of stay did not differ among the groups. The median times to absolute neutrophil count and platelet recovery were 10 days (P=0.75) and 14 days (P=0.17), respectively. Obese patients had a lower 100-day mortality compared with other weight groups, although this did not translate into an OS benefit. OS and disease relapse were similar among the groups. Our study demonstrates that use of adjusted body weight to calculate chemotherapy doses does not negatively have an impact on outcomes in obese patients undergoing auto-SCT with BU, CY and etoposide.

Tranexamic acid reduces the risk of bleeding among patients undergoing cardiac surgery, but it is unclear whether this leads to improved outcomes. Furthermore, there are concerns that tranexamic acid may have prothrombotic and proconvulsant effects. In a trial with a 2-by-2 factorial design, we randomly assigned patients who were scheduled to undergo coronary-artery surgery and were at risk for perioperative complications to receive aspirin or placebo and tranexamic acid or placebo. The results of the tranexamic acid comparison are reported here. The primary outcome was a composite of death and thrombotic complications (nonfatal myocardial infarction, stroke, pulmonary embolism, renal failure, or bowel infarction) within 30 days after surgery. Of the 4662 patients who were enrolled and provided consent, 4631 underwent surgery and had available outcomes data; 2311 were assigned to the tranexamic acid group and 2320 to the placebo group. A primary outcome event occurred in 386 patients (16.7%) in the tranexamic acid group and in 420 patients (18.1%) in the placebo group (relative risk, 0.92; 95% confidence interval, 0.81 to 1.05; P=0.22). The total number of units of blood products that were transfused during hospitalization was 4331 in the tranexamic acid group and 7994 in the placebo group (Ptranexamic acid group and in 2.8% of the patients in the placebo group (P=0.001), and seizures occurred in 0.7% and 0.1%, respectively (P=0.002 by Fisher's exact test). Among patients undergoing coronary-artery surgery, tranexamic acid was associated with a lower risk of bleeding than was placebo, without a higher risk of death or thrombotic complications within 30 days after surgery. Tranexamic acid was associated with a higher risk of postoperative seizures.

The aim of this study is to evaluate the organ doses of patients undergoing hepatic chemoembolization procedures performed in two hospitals in the city of Recife-Brazil. Forty eight patients undergoing fifty hepatic chemoembolization procedures were investigated. For the 20 cases with PA projection only, organ and tissue absorbed doses as well as radiation risks were calculated. For this purpose organs and tissues dose to KAP conversion coefficients were calculated using the mesh-based phantom series FASH and MASH coupled to the EGSnrc Monte Carlo code. Clinical, dosimetric and irradiations parameters were registered for all patients. The maximum organ doses found were 1.72 Gy, 0.65Gy, 0.56 Gy and 0.33 Gy for skin, kidneys, adrenals and liver, respectively. (authors)

Advances in cancer therapy have improved the long term survival of young patients suffering from malignancies. However adverse effects of the treatment are sterlity and loss of gonadal function especially in females. Preservation of fertility in males by sperm freezing is more practical and already established. For young women undergoing cancer treatment , the availability of preserving the gonadal function and fertility has just begun.Today we can crypreserve the oocytes, the embryos or rhe ovarian tissue and those undergoing pelvic irradtion, laparascopic can be cnsidered. Because women with non-gynelical malagnencies seek advice from a general surgeon or a medical onconologist, increasing awawreness of physician and general public is recommended. (author)

This paper quantifies the extent of the radiation hazard to personnel from horses undergoing scintigraphy using technetium{sup 99m} methylene diphosphonate ({sup 99m}Tc{sup m}-MDP). From the data produced it is possible to derive safe working protocols which are comfortably within the legislated limits for whole body doses as set out in the Ionising Radiations Regulations 1985. Measurements were made of the surface and environmental activities which result from individuals undergoing scintigraphic evaluation and also from urine contaminated bedding. The use of both high and low activities in the assessment of the radiation hazard to personnel and owners is considered. (author).

Full Text Available Background and Objectives Chronic renal disease is a threatening condition for the health, economic, and social status of the affected person and his/her family. Patients undergoing hemodialysis encounter mental and health problems; the current study aimed at predicting resilience via social support and illness perceptions among patients undergoing hemodialysis. Methods The current descriptive-correlational study had a statistical population including 308 patients undergoing hemodialysis in Kerman, Iran, in 2017. Based on the Krejcie-Morgan table, the minimum required sample size was 169. The sample was selected using a convenience sampling method. Data collection tools were the Connor-Davidson resilience scale, the medical outcome study (MOS social support survey developed by Sherbourne and Stewart, and the brief illness perception questionnaire developed by Broadbent et al. Data were analyzed using a Pearson correlation coefficient and a stepwise regression analysis via SPSS version 19. Results Results indicated that resilience was significantly and positively related to social support (r = 0.318, P < 0.05 and illness perceptions (r = 0.165, P < 0.05. Among the subscales of social support, emotional support, tangible support, and social interaction could predict resilience, and among the subscales of illness perceptions, only cognitive representation could predict resilience. Conclusions The obtained results demonstrated that resilience was significantly and positively related to social support and illness perceptions. Additionally, the subscales of social support and illness perceptions could predict resilience among the patients undergoing hemodialysis.

Kennedy, C

2012-02-01

Thromboprophylaxis for women undergoing caesarean section (CS) was introduced in the hospital in 1995. This study audited the use of tinzaparin prophylaxis in a nested cohort of women who screened negative for diabetes mellitus at 28 weeks gestation. All the women had their weight measured and BMI calculated at the first antenatal visit. Of the 284 women, 68 (24%) had a CS and all received tinzaparin. Of the 68, however, 94% received a dose lower than recommended. Compliance with prophylaxis was complete but compliance with the recommended dosage was suboptimal, which may result in venous thromboembolism after CS despite thromboprophylaxis.

Adit

2014-01-01

Full Text Available Dermatillomania is a disorder in which a person habitually picks their skin, and this is a form of self-injury. It can involve any part of the body, but usually involves the face, neck, arms and shoulders. Symptoms often follow an event that has caused severe emotional distress. A dermatillomania or compulsive skin picking episode may be a conscious response to anxiety or depression but is frequently done as an unconscious habit. In this case report, a patient undergoing orthodontic treatment was found to be suffering from dermatillomania and was treated using psychological counseling.

Full Text Available The primary purpose of this study was to determine the oral manifestations of patients undergoing dialysis. Two subgroups of the population were studied: (1 Those who have been on dialysis for less than one year, (2 those who have been on dialysis for more than one year. Two dental indices–periodontal index and decayed, missing, filled index were used to identify periodontal status, dental canes activity. Data were compiled and analyzed by using the unpaired t-test. Results suggested that 100% (n = 26 of the patients undergoing dialysis presented with some form of periodontal disease (mean value = 2.24, standard deviation = 1.33. Majority of the patients displayed either established periodontal disease (57.6% or the beginning of periodontal disease (38 4%. Approximately, 70% of the patients had high decayed, missing, filled index (mean value = 6.19, standard deviation = 6.40. Findings led to the conclusion that patients on dialysis need comprehensive professional oral care and self-care instructions. The source of infection in oral cavity can cause variety of systemic diseases, causing morbidity and mortality in these immune-suppressed patients.

This study evaluated the efficacy and safety of oral triiodothyronine (T3; Tetronine, Dalim BioTech, Korea) for infants and children undergoing cardiopulmonary bypass in an Indonesian population. We performed a single-center, randomized, double-blind, and placebo-controlled trial in children aged 3 years and younger undergoing congenital heart disease operations with cardiopulmonary bypass. We administered oral T3 (1 μg/kg per body weight/dose) or placebo (saccharum lactis) by nasogastric tube every 6 hours for 60 hours after induction of anesthesia. The primary end point, time to extubation, was compared with Cox regression. The modified intention-to-treat group included 101 placebo and 104 treated patients. The stratified log-rank test did not show a significant treatment difference (p = 0.061) for time to extubation, but after adjustment for age, the nutritional Z score, and Aristotle surgical complexity, the hazard ratio was 1.33 (95% confidence interval, 1.00 to 1.76; p = 0.049). The effect of T3 was stronger in the strata aged 5 months and younger (hazard ratio, 1.86; 95% confidence interval 1.02 to 3.39; p = 0.043). Median intubation time was 47.3 hours for the placebo and 32.1 hours for the T3 group in aged 5 months and younger. Adverse events rates, including arrhythmia, were similar between groups, although sepsis was more frequent with placebo. Oral T3 supplementation may shorten time to extubation in children undergoing congenital heart disease operations, particularly infants aged 5 months or younger. Administration is relatively safe, simple and inexpensive. Copyright © 2017 The Society of Thoracic Surgeons. Published by Elsevier Inc. All rights reserved.

Assessing the neurodevelopmental status of infants with congenital heart disease before surgery provides a means of identifying those at heightened risk of developmental delay. This study aimed to investigate factors impacting clinical feasibility of pre-operative neurodevelopmental assessment of infants undergoing early open heart surgery. Infants who underwent open heart surgery prior to 4 months of age participated in this cross-sectional study. The Test of Infant Motor Performance and Prechtl's Assessment of General Movements were undertaken on infants pre-operatively. When assessments could not be undertaken, reasons were ascribed to either infant or environmental circumstances. Demographic data and Aristotle scores were compared between groups of infants who did or did not undergo assessment. Binary logistic regression was used to explore associations. A total of 60 infants participated in the study. Median gestational age was 38.78 weeks (interquartile range: 36.93-39.72). Of these infants, 37 (62%) were unable to undergo pre-operative assessment. Twenty-four (40%) could not complete assessment due to infant-related factors and 13 (22%) due to environmental-related factors. For every point increase in the Aristotle Patient-Adjusted Complexity score, the infants likelihood of being unable to undergo assessment increased by 35% (odds ratio: 0.35; 95% confidence interval: 1.03-1.77, P = 0.03). Over half of the infants undergoing open heart surgery were unable to complete pre-operative neurodevelopmental assessment. The primary reason for this was infant-related medical instability. Findings suggest further research is warranted to investigate whether the Aristotle Patient-Adjusted Complexity score might serve as an indicator to inform developmental surveillance with this medically fragile cohort. © 2017 Paediatrics and Child Health Division (The Royal Australasian College of Physicians).

Previous studies have indicated that music decreases intraoperative sedative requirements in patients undergoing surgical procedures under regional anesthesia. In this study we sought to determine whether this decrease in sedative requirements results from music or from eliminating operating room (OR) noise. A secondary aim of the study was to examine the relationship of response to intraoperative music and participants' culture (i.e., American versus Lebanese). Eighty adults (36 American and 54 Lebanese) undergoing urological procedures with spinal anesthesia and patient-controlled IV propofol sedation were randomly assigned to intraoperative music, white noise, or OR noise. We found that, controlling for ambient OR noise, intraoperative music decreases propofol requirements (0.004 +/- 0.002 mg . kg(-1) . min(-1) versus 0.014 +/- 0.004 mg . kg(-1) . min(-1) versus 0.012 +/- 0.002 mg . kg(-1) . min(-1); P = 0.026). We also found that, regardless of group assignment, Lebanese patients used less propofol as compared with American patients (0.005 +/- 0.001 mg . kg(-1) . min(-1) versus 0.017 +/- 0.003 mg . kg(-1) . min(-1); P = 0.001) and that, in both sites, patients in the music group required less propofol (P noise, intraoperative music decreases propofol requirements of both Lebanese and American patients who undergo urological surgery under spinal anesthesia.

Full Text Available Objective: to evaluate the self-esteem of cancer patients undergoing chemotherapy. Method: descriptive analytical cross-sectional study with a quantitative approach. Around 156 patients that attended an oncology unit of a mid-sized hospital participated in the study. Results: we found a higher frequency of patients with high self-esteem, but some of them showed average or low self-esteem. The scale showed a Cronbach's alpha value of 0.746, by considering its acceptable internal consistency for the evaluated items. No independent variables showed significant associations with self-esteem. Conclusion: the cancer patients evaluated have presented high self-esteem; thus, it becomes crucial for nursing to plan the assistance of patients undergoing chemotherapy treatments, which enables actions and strategies that meet their physical and psychosocial conditions, aiming to maintain and rehabilitate these people's emotional aspects.

As the potential role of genetic testing in disease prevention and management grows, so does concern about differences in uptake of genetic testing across social and racial groups. Characteristics of how genetic tests are delivered may influence willingness to undergo testing and, if they affect population subgroups differently, alter disparities in testing. Conjoint analysis study of the effect of 3 characteristics of genetic test delivery (ie, attributes) on willingness to undergo genetic testing for cancer risk. Data were collected using a random digit dialing survey of 128 African American and 209 white individuals living in the United States. Measures included conjoint scenarios, the Revised Health Care System Distrust Scale (including the values and competence subscales), health insurance coverage, and sociodemographic characteristics. The 3 attributes studied were disclosure of test results to the health insurer, provision of the test by a specialist or primary care doctor, and race-specific or race-neutral marketing. In adjusted analyses, disclosure of test results to insurers, having to get the test from a specialist, and race-specific marketing were all inversely associated with willingness to undergo the genetic test, with the greatest effect for the disclosure attribute. Racial differences in willingness to undergo testing were not statistically significant (P=0.07) and the effect of the attributes on willingness to undergo testing did not vary by patient race. However, the decrease in willingness to undergo testing with insurance disclosure was greater among individuals with high values distrust (P=0.03), and the decrease in willingness to undergo testing from specialist access was smaller among individuals with high competence distrust (P=0.03). Several potentially modifiable characteristics of how genetic tests are delivered are associated with willingness to undergo testing. The effect of 2 of these characteristics vary according to the level of

2014-02-01

Information on the coexistence of lumbar spondylosis and its influence on overall levels of pain and function in patients with advanced knee osteoarthritis (OA) undergoing total knee arthroplasty (TKA) would be valuable for patient consultation and management. The purposes of this study were to document the prevalence and severity of coexisting lumbar spondylosis in patients with advanced knee OA undergoing TKA and to determine whether the coexisting lumbar spondylosis at the time of TKA adversely affects clinical scores in affected patients before and 2 years after TKA. Radiographic lumbar spine degeneration and lumbar spine symptoms including lower back pain, radiating pain at rest, and radiating pain with activity were assessed in 225 patients undergoing TKA. In addition, the WOMAC score and the SF-36 scores were evaluated before and 2 years after TKA. Potential associations of radiographic lumbar spine degeneration and lumbar spine symptom severities with pre- and postoperative WOMAC subscales and SF-36 scores were examined. All 225 patients had radiographic degeneration of the lumbar spine, and the large majority (89% [200 of 225]) had either moderate or severe spondylosis (72% and 17%, respectively). A total of 114 patients (51%) had at least one moderate or severe lumbar spine symptom. No association was found between radiographic severity of lumbar spine degeneration and pre- and postoperative clinical scores. In terms of lumbar spine symptoms, more severe symptoms were likely to adversely affect the preoperative WOMAC and SF-36 physical component summary (PCS) scores, but most of these adverse effects improved by 2 years after TKA with the exception of the association between severe radiating pain during activity and a poorer postoperative SF-36 PCS score (regression coefficient = -5.41, p = 0.015). Radiographic lumbar spine degeneration and lumbar spine symptoms are common among patients with advanced knee OA undergoing TKA. Severe lumbar spine symptoms

2010-03-01

With the transition from infectious disease and acute illness to chronic disease and degenerative illness as leading causes of death, health-related quality of life has become an important aspect in assessing the burden of chronic disease. The quality of life of haemodialysis patients has been studied extensively; however, very limited research using exploratory descriptive design has been carried out in this area in China. The aim of this study was to explore health-related quality of life of end-stage renal disease patients undergoing haemodialysis in China. This study used the qualitative research design approach. A semi-structured, in-depth interview was conducted with 16 haemodialysis patients in two hospitals using Colaizzi's phenomenological method to transcribe and analyse the data. The results of this study showed that dialysis patients show improvement in physical competence, but they also experienced emotional instability and psychological distress, financial burdens, inadequate disease knowledge and less social support which influenced their quality of life. To optimise the patients undergoing dialysis health-related quality of life, support of psycho-social-economical aspects should be enhanced. Health care providers should give haemodialysis patients thorough health education, individualised psychological and emotional intervention and adequate social support to optimise health-related quality of life.

Coagulation profile in patients undergoing video-assisted thoracoscopic lobectomy: A randomized, controlled trial.

Directory of Open Access Journals (Sweden)

Full Text Available Knowledge about the impact of Low-Molecular-Weight Heparin (LMWH on the coagulation system in patients undergoing minimal invasive lung cancer surgery is sparse. The aim of this study was to assess the effect of LMWH on the coagulation system in patients undergoing Video-Assisted Thoracoscopic Surgery (VATS lobectomy for primary lung cancer.Sixty-three patients diagnosed with primary lung cancer undergoing VATS lobectomy were randomized to either subcutaneous injection with dalteparin (Fragmin® 5000 IE once daily or no intervention. Coagulation was assessed pre-, peri-, and the first two days postoperatively by standard coagulation blood test, thromboelastometry (ROTEM® and thrombin generation.Patients undergoing potential curative surgery for lung cancer were not hypercoagulable preoperatively. There was no statistically significant difference in the majority of the assessed coagulation parameters after LMWH, except that the no intervention group had a higher peak thrombin and a shorter INTEM clotting time on the first postoperative day and a lower fibrinogen level on the second postoperative day. A lower level of fibrin d-dimer in the LMWH group was found on the 1. and 2.postoperative day, although not statistical significant. No differences were found between the two groups in the amount of bleeding or number of thromboembolic events.Use of LMWH administered once daily as thromboprophylaxis did not alter the coagulation profile per se. As the present study primarily evaluated biochemical endpoints, further studies using clinical endpoints are needed in regards of an optimized thromboprophylaxis approach.

Reduction of cognitive function is a possible side effect after the use of cardiopulmonary bypass (CPB) during cardiac surgery. Since it has been proven that piracetam is cerebroprotective in patients undergoing coronary bypass surgery, we investigated the effects of piracetam on the cognitive performance of patients undergoing open heart surgery. Patients scheduled for elective open heart surgery were randomized to the piracetam or placebo group in a double-blind study. Patients received 12 g of piracetam or placebo at the beginning of the operation. Six neuropsychological subtests from the Syndrom Kurz Test and the Alzheimer's Disease Assessment Scale were performed preoperatively and on day 3, postoperatively. To assess the overall cognitive function and the degree of cognitive decline across all tests after the surgery, we combined the six test-scores by principal component analysis. A total of 88 patients with a mean age of 67 years were enrolled into the study. The mean duration of CPB was 110 minutes. Preoperative clinical parameters and overall cognitive functions were not significantly different between the groups. The postoperative combined score of the neuropsychological tests showed deterioration of cognitive function in both groups (piracetam: preoperative 0.19 ± 0.97 vs. postoperative -0.97 ± 1.38, p piracetam did not perform better than those taking placebo, and both groups had the same decline of overall cognitive function (p = 0.955). Piracetam had no cerebroprotective effect in patients undergoing open heart surgery. Unlike the patients who underwent coronary surgery, piracetam did not reduce the early postoperative decline of neuropsychological abilities in heart valve patients.

2013-01-01

Full Text Available The number of patients with a previously diagnosed malignancy who need cardiac surgery is increasing. Patients with hematological malignancies represent only 0.38% of all patients undergoing cardiac surgery. The literature in this subset of patients is limited to only a few retrospective case series, with limited number of patients undergoing emergency cardiac surgery. We describe three cases with hematological malignancies namely chronic myelogenous leukemia, acute promyelocytic leukemia and chronic lymphocytic leukemia presenting for coronary artery bypass grafting (CABG. Two patients were taken up for emergency CABG in view of ongoing ischemia, one of them was on preoperative intra-aortic balloon pump support. No mortality was observed. Two patients needed transfusion of blood products which was guided by thromboelastography. One patient developed superficial sternal wound infection requiring antibiotic therapy.

2013-01-01

At present, limited experience exists on the treatment of atrial fibrillation (AF) in patients undergoing mitral valve repair (MVR) for Barlow disease. The aim of this investigation was to prospectively evaluate the radiofrequency ablation of AF in patients undergoing MVR for severe regurgitation due to Barlow disease. From January 1, 2007 to December 31, 2010, out of 85 consecutive patients with Barlow disease, 27 with AF underwent RF ablation associated with MVR. They were examined every 4 months in the first year after surgery and thereafter twice yearly. At follow-up, AF was observed in 4/25 (16.0%). NYHA (New York Heart Association) functional class improved significantly, with no patients in class III or IV (before surgery, 81.5% had been). Otherwise, among 58 patients in sinus rhythm, 6 (11%) developed AF during follow-up. No clinical or echocardiographic predictive factor was found in this subgroup. Results from our investigation suggest that radiofrequency ablation of AF in patients with Barlow disease undergoing MVR for severe regurgitation is effective and should be considered in every patient with Barlow disease and AF undergoing valve surgical repair.

To explore the prevalence and risk factors for depression in men undergoing different assisted reproductive technique (ART) treatments in Chinese population. This was a prospective study of 844 men undergoing ART treatments. All men were distributed to four groups, according to they received treatments. The treatments included IUI (intrauterine insemination), IVF(in vitro fertilization), ICSI(intra cytoplasmatic sperm injection) and TESA/PESA (percutaneous epididymal sperm aspiration/testicular sperm aspiration). Their symptoms of depression were measured with use of the Center for Epidemiologic Studies of Depression scale(CES-D). Data were collected about age, BMI, education, duration of marriage, duration of infertility, smoking, type of infertility, infertility causes, history of ejaculation failure, and financial burden of the treatment. We estimated the prevalence of depressive symptom in men undergoing different ART and used logistic regression models to identify risk factors for depression in different groups. The overall prevalence of depression was 13.3 % for men undergoing ART treatments: 14.5 % of IUI group, 12.4 % of IVF group, 19.2 % of ICSI group and 6.2 % of TESA/PESA group. Prevalence of depression among IUI group, IVF group and ICSI group were not significantly different. For IUI group, the factors were found to increase depression risk were treatment financial burden and duration of marriage, to decrease depression risk was age. For IVF group, the risk factors independently associated with depression were both male and female infertility, unexplained infertility, and history of ejaculation failure. In a sample of Chinese men undergoing ART treatments, the prevalence of depression was higher than other country. The risk factors for depression varied in different ART treatments groups. when routine screening to identify the sub-group of vulnerable men which need counselling before ART treatments, we should also consider which pattern of ART

Infants born with orofacial clefts (OFCs undergo functional, anatomical, and aesthetic surgery. The aim of the present study was to determine whether infants with OFC and undergoing OFC surgery show deteriorated sleep and cortisol secretion compared with healthy controls and with their presurgery status.Methods: A total of 27 infants with OFC (mean age: 22 weeks and 30 healthy controls (mean age: 23 weeks took part in the study. For infants with OFC, sleep actigraphy was performed and saliva cortisol was analyzed 5 days before, during, and 5 days after surgery. For controls, sleep and saliva cortisol were assessed similarly, except for the period taken up with surgery.Results: Compared with healthy controls, infants with OFC undergoing OFC surgery did not differ in sleep and cortisol secretion. Their sleep and cortisol secretion did deteriorate during the perisurgical period but recovered 5 days postsurgery. Conclusion: In infants with OFC undergoing corrective surgery, the pattern of results for sleep and cortisol suggests that OFC surgery does not seem to constitute a traumatic event with long-term consequences.

Hypothermia prevention strategies during MRI scanning under general anesthesia in infants may pose a challenge due to the MRI scanner's technical constraints. Previous studies have demonstrated conflicting results related to increase or decrease in post-scan temperatures in children. We noted occurrences of post-scan hypothermia in anesthetized infants despite the use of routine passive warming techniques. The aims of our quality improvement project were (a) to identify variables associated with post-scan hypothermia in infants and (b) to develop and implement processes to reduce occurrence of hypothermia in neonatal intensive care unit (NICU) infants undergoing MRI. One hundred sixty-four infants undergoing MRI scanning were prospectively audited for post-scan body temperatures. A multidisciplinary team identified potential variables associated with post-scan hypothermia and designed preventative strategies: protocol development, risk factor identification, vigilance and use of a vacuum immobilizer. Another audit was performed, specifically focusing on NICU infants. In the initial phase, we found that younger age (P = 0.002), lower weight (P = 0.005), lower pre-scan temperature (P < 0.01), primary anesthetic technique with propofol (P < 0.01), advanced airway devices (P = 0.02) and being in the NICU (P < 0.01) were associated with higher odds for developing post-scan decrease in body temperature. Quality improvement processes decreased the occurrence of hypothermia in NICU infants undergoing MRI scanning from 65% to 18% (95% confidence interval for the difference, 26-70%, P < 0.001). Several variables, including being in the NICU, are associated with a decrease in post-scan temperature in infants undergoing MRI scanning under sedation/general anesthesia. Implementation of strategies to prevent hypothermia in infants may be challenging in the high-risk MRI environment. We were able to minimize this problem in clinical practice by applying quality improvement

The prognostic effects of poor nutritional status and cardiac cachexia on coronary artery disease (CAD) are not clearly understood. A well-accepted nutritional status parameter, the prognostic nutritional index (PNI), which was first demonstrated to be valuable in patients with cancer and those undergoing gastrointestinal surgery, was introduced to patients requiring coronary artery bypass grafting (CABG). The aim of the present study was to evaluate the prognostic value of PNI in patients with CAD undergoing CABG. We evaluated the in-hospital and long-term (3-y) prognostic effect of PNI on 644 patients with CAD undergoing CABG. Baseline characteristics and outcomes were compared among the patients by PNI and categorized accordingly: Q1, Q2, Q3, and Q4. Patients with lower PNI had significantly higher in-hospital and long-term mortality. Patients with lower PNI levels (Q1) had higher in-hospital mortality and had 12 times higher mortality rates than those with higher PNI levels (Q4). The higher PNI group had the lower rates and was used as the reference. Long-term mortality was higher in patients with lower PNI (Q1)-4.9 times higher than in the higher PNI group (Q4). In-hospital and long-term mortality rates were similar in the non-lower PNI groups (Q2-4). The present study demonstrated that PNI, calculated based on serum albumin level and lymphocyte count, is an independent prognostic factor for mortality in patients undergoing CABG.

To investigate whether malnutrition is associated with poor prognosis of patients who undergo salvage esophagectomy. We examined the association between the preoperative prognostic nutritional index (PNI) and prognosis of patients who undergo salvage esophagectomy. We conducted a single-center retrospective study and reviewed hospital patient records for tumor characteristics and patient outcomes. Univariate and multivariate survival analyses were carried out using the Cox proportional hazards regression model. Thirty-two patients with esophageal squamous cell carcinoma (ESCC) who underwent salvage esophagectomy between 1998 and 2015 at our Institute were included in this study. Univariate analysis revealed that clinical response (p=0.045), preoperative PNI (pnutritional status is associated with the prognosis of patients undergoing salvage esophagectomy.

Patients undergoing lobectomy are at significantly increased risk of lung injury. One-lung ventilation is the most commonly used technique to maintain ventilation and oxygenation during the operation. It is a challenge to choose an appropriate mechanical ventilation strategy to minimize the lung injury and other adverse clinical outcomes. In order to understand the available evidence, a systematic review was conducted including the following topics: (I) protective ventilation (PV); (II) mode of mechanical ventilation [e.g., volume controlled (VCV) versus pressure controlled (PCV)]; (III) use of therapeutic hypercapnia; (IV) use of alveolar recruitment (open-lung) strategy; (V) pre-and post-operative application of positive end expiratory pressure (PEEP); (VI) Inspired Oxygen concentration; (VII) Non-intubated thoracoscopic lobectomy; and (VIII) adjuvant pharmacologic options. The recommendations of class II are non-intubated thoracoscopic lobectomy may be an alternative to conventional one-lung ventilation in selected patients. The recommendations of class IIa are: (I) Therapeutic hypercapnia to maintain a partial pressure of carbon dioxide at 50-70 mmHg is reasonable for patients undergoing pulmonary lobectomy with one-lung ventilation; (II) PV with a tidal volume of 6 mL/kg and PEEP of 5 cmH 2 O are reasonable methods, based on current evidence; (III) alveolar recruitment [open lung ventilation (OLV)] may be beneficial in patients undergoing lobectomy with one-lung ventilation; (IV) PCV is recommended over VCV for patients undergoing lung resection; (V) pre- and post-operative CPAP can improve short-term oxygenation in patients undergoing lobectomy with one-lung ventilation; (VI) controlled mechanical ventilation with I:E ratio of 1:1 is reasonable in patients undergoing one-lung ventilation; (VII) use of lowest inspired oxygen concentration to maintain satisfactory arterial oxygen saturation is reasonable based on physiologic principles; (VIII) Adjuvant drugs

Full Text Available Objectives. To investigate the efficacy and safety of perioperative endocrine therapy (PET for patients with Cushing’s syndrome (CS undergoing retroperitoneal laparoscopic adrenalectomy (RLA. Methods. The novel, simplified PET modality of 82 patients who underwent RLA procedures for CS were studied. Clinical manifestations were observed for all patients on days 1 and 5 postoperatively, and clinical data, such as blood pressure (BP, levels of serum cortisol, adrenocorticotropin (ACTH, blood glucose, and electrolytes, were acquired and analyzed. Results. Supraphysiological doses of glucocorticoid were administered during the perioperative period, and the dosage was reduced gradually. In all 82 cases, the RLAs were performed successfully without any perioperative complication, such as steroid withdrawal symptoms. The patient’s symptoms and signs were improved quickly and safely during the hospital days. The serum cortisol and potassium levels were rather stable on days 1 and 5 postoperatively, and most were within the normal range. The clinical manifestations, serum levels of cortisol, ACTH, and potassium in most patients restored to normal gradually after several months (mean, 6.7 ± 1.2 months, except for one patient undergoing bilateral adrenalectomy. Conclusions. This perioperative endocrine therapy for patients with Cushing’s syndrome (mainly for adrenocortical adenoma undergoing retro-laparoscopic adrenalectomy is both effective and safe.

This study aimed to determine whether dental calculus formation is really higher among patients with chronic kidney disease undergoing hemodialysis than among controls. Furthermore, the study evaluated correlations between dental calculus formation and dental plaque, variables that are related to renal disease and/or saliva composition. The Renal Group was composed of 30 patients undergoing hemodialysis, whereas the Healthy Group had 30 clinically healthy patients. Stimulated whole saliva and parotid saliva were collected. Salivary flow rate and calcium and phosphate concentrations were determined. In the Renal Group the saliva collection was carried out before and after a hemodialysis session. Patients from both groups received intraoral exams, oral hygiene instructions, and dental scaling. Three months later, the dental calculus was measured by the Volpe-Manhold method to determine the rate of dental calculus formation. The Renal Group presented a higher rate of dental calculus formation (p dental calculus formation and whole saliva flow rate in the Renal Group after a hemodialysis session (r = 0.44, p dental calculus was associated with phosphate concentration in whole saliva from the Renal Group (p dental calculus formation, probably due to salivary variables.

The American Academy of Orthopaedic Surgeons, in collaboration with the American Dental Association, has developed Appropriate Use Criteria (AUC) for the Management of Patients with Orthopaedic Implants Undergoing Dental Procedures. Evidence-based information, in conjunction with the clinical expertise of physicians, was used to develop the criteria to improve patient care and obtain best outcomes while considering the subtleties and distinctions necessary in making clinical decisions. The Management of Patients with Orthopaedic Implants Undergoing Dental Procedures AUC clinical patient scenarios were derived from indications of patients with orthopaedic implants presenting for dental procedures, as well as from current evidence-based clinical practice guidelines and supporting literature to identify the appropriateness of the use of prophylactic antibiotics. The 64 patient scenarios and 1 treatment were developed by the writing panel, a group of clinicians who are specialists in this AUC topic. Next, a separate, multidisciplinary, voting panel (made up of specialists and nonspecialists) rated the appropriateness of treatment of each patient scenario using a 9-point scale to designate a treatment as Appropriate (median rating, 7 to 9), May Be Appropriate (median rating, 4 to 6), or Rarely Appropriate (median rating, 1 to 3).

Our objective was to describe our experience of managing a cohort of adult patients prescribed direct oral anticoagulants (DOACs) undergoing dentoalveolar procedures between November 2012 and May 2016. Prior to conducting a procedure a formal assessment was made of each patient's anticoagulation treatment. A specific plan was then formulated, balancing the risk of bleeding with the risk of thrombosis. Patients received a telephone consultation one week following treatment to assess any post-operative bleeding. Eighty-two patients underwent 111 oral surgical procedures, the majority of which were dental extractions. In the case of 35 (32%) procedures, advice was given to omit the DOAC, either before or after treatment. There was no bleeding following the majority of procedures. Persistent bleeding followed 15 (13.5%) procedures, of which 7 (6.3%) procedures required specific intervention. The majority of patients prescribed DOACs can undergo dentoalveolar procedures safely. Important considerations when planning treatment are: (i) when the patient usually takes their dose of DOAC, (ii) the time the procedure is performed and, (iii) when the DOAC is taken post-procedure. In our experience, if these factors are considered carefully, omission of DOAC doses is unlikely to be required for most patients.

Cobalamin (vitamin B12 deficiency is a common cause of neuropsychiatric symptoms and affects up to 40% of elderly people. The relationship between cobalamin deficiency and the occurrence of delirium after cardiac surgery has not been examined in previous studies. We examined the relationship between cobalamin deficiency and delirium in elderly patients undergoing coronary artery bypass grafting (CABG surgery.Material and methods: A total of 100 patients with cobalamin deficiency undergoing CABG were enrolled in this retrospective study. Control group comprised 100 patients without cobalamin deficiency undergoing CABG. Patients aged 65 years or over were included. Diagnosis of delirium was made using Intensive Care Delirium Screening Checklist. Delirium severity was measured using the Delirium Rating Scale-revised-98.Results: Patients with cobalamin deficiency had a significantly higher incidence of delirium (42% vs 26%; P=0.017 and higher delirium severity scores (16.5±2.9 vs 15.03±2.48; P=0.034 than patients without cobalamin deficiency. Cobalamin levels were significantly lower in patients with delirium than patients without delirium (P=0.004. Delirium severity score showed a moderate correlation with cobalamin levels (Ρ=-0.27; P=0.024. Logistic regression analysis demonstrated that

TEMPERATURE STRUCTURE OF PROTOPLANETARY DISKS UNDERGOING LAYERED ACCRETION

Lesniak, M. V.; Desch, S. J.

2011-01-01

We calculate the temperature structures of protoplanetary disks (PPDs) around T Tauri stars heated by both incident starlight and viscous dissipation. We present a new algorithm for calculating the temperatures in disks in hydrostatic and radiative equilibrium, based on Rybicki's method for iteratively calculating the vertical temperature structure within an annulus. At each iteration, the method solves for the temperature at all locations simultaneously, and converges rapidly even at high (>>10 4 ) optical depth. The method retains the full frequency dependence of the radiation field. We use this algorithm to study for the first time disks evolving via the magnetorotational instability. Because PPD midplanes are weakly ionized, this instability operates preferentially in their surface layers, and disks will undergo layered accretion. We find that the midplane temperatures T mid are strongly affected by the column density Σ a of the active layers, even for fixed mass accretion rate M-dot . Models assuming uniform accretion predict midplane temperatures in the terrestrial planet forming region several x 10 2 K higher than our layered accretion models do. For M-dot -7 M sun yr -1 and the column densities Σ a -2 associated with layered accretion, disk temperatures are indistinguishable from those of a passively heated disk. We find emergent spectra are insensitive to Σ a , making it difficult to observationally identify disks undergoing layered versus uniform accretion.

The purpose of this study is to investigate how family-related opinions and stressful situations are related to psychological distress in women undergoing infertility treatment. The subjects in this cross-sectional study were recruited from female patients undergoing infertility treatment (n = 2540) at 70 infertility treatment institutions in Japan. Because of non-participation or missing data, the number of subjects included in the analysis was 635 (response rate, 25.0%). The family-related opinions and stressful situations were evaluated using the original questions. Psychological distress was assessed using a self-report measure, the Kessler Six-question Psychological Distress Scale (K6). The K6 scores of the following participants were significantly (p women should devote themselves to their household duties" those who had considered stopping treatment, those without the opinion that "married life without children is favorable" and those who had experienced stressful situations such as inadequate explanation by doctors, frustration of multiple failed attempts, differences of opinion with the partner, and lack of knowledge regarding when to stop treatment. Family-related opinions and stressful situations associated with psychological distress in women undergoing infertility treatment are outlined. The results of this study may contribute to the prevention of and care for psychological distress in female patients undergoing infertility treatment.

The risks and costs of transfusion are a great concern in the area of pediatric spine surgery, because it is a blood-intensive procedure with a high risk for transfusion. Therefore, determining the predictors of transfusion in this patient population is an important first step and has the potential to improve upon the current approaches to reducing transfusion rates. In this study, we reveal several predictors of transfusion in a pediatric patient population undergoing spine surgery. In turn, we present a general rule of thumb ("rule of two's") for gauging transfusion risk, thus enhancing the surgeon's approach to avoiding transfusion in certain clinical scenarios. This study was conducted to determine the main factors of transfusion in a population of pediatric patients undergoing scoliosis surgery. The goal was to present an algorithm for quantifying the true risk of transfusion for various patient groups that would highlight patients "at high risk" for transfusion. This is especially important in light of the various risks associated with undergoing a transfusion, as well as the costs involved in maintaining and disposing of exogenous blood materials. This is a retrospective review of a group of children who underwent scoliosis surgery between 1988 and 1995 at an academic institution. A total of 290 patients were analyzed in this study, of which 63 were transfused and 227 were not. No outcomes measures were used in this study. A retrospective review of 290 patients presenting to our institution for scoliosis surgery was conducted, with a focus on socioclinical data related to transfusion risk. Univariate analysis and logistic regression were used to quantify the determinants of transfusion risk. Univariate analysis identified many factors that were associated with the risk of transfusion. However, it is clear that several of these factors are dependent on each other, obscuring the true issues driving transfusion need. We used multivariate analysis to control for

2017-06-01

Objective This study was designed to compare the effectiveness of granisetron plus dexamethasone for preventing postoperative nausea and vomiting (PONV) in patients undergoing laparoscopic surgery. Methods We searched the literature in the Cochrane Library, PubMed, EMBASE, and CNKI. Results In total, 11 randomized controlled trials were enrolled in this analysis. The meta-analysis showed that granisetron in combination with dexamethasone was significantly more effective than granisetron alone in preventing PONV in patients undergoing laparoscopy surgery. No significant differences in adverse reactions (dizziness and headache) were found in association with dexamethasone. Conclusion Granisetron in combination with dexamethasone was significantly more effective than granisetron alone in preventing PONV in patients undergoing laparoscopic surgery, with no difference in adverse reactions between the two groups. Granisetron alone or granisetron plus dexamethasone can be used to prevent PONV in patients undergoing laparoscopic surgery.

An association between celiac disease and renal diseases has been suggested, but the results are controversial. To investigate the prevalence of celiac disease autoimmunity among individuals undergoing renal biopsies and to evaluate whether co-existent celiac autoimmunity influences the clinical outcome of the renal disease. The prevalence of celiac autoimmunity (previous diagnosis of celiac disease or positive tissue transglutaminase antibodies) was determined in 827 consecutive patients undergoing kidney biopsies due to clinical indications. Up to 15 years' follow-up data on kidney function and co-morbidities were obtained. Celiac autoimmunity was found in 45 (5.4%) patients. Among the IgA nephropathy patients, 8.2% of had celiac autoimmunity. At the time of kidney biopsy and after a median follow-up of 5 to 6 years, renal function measured by estimated glomerular filtration rate (eGFR) was inferior in IgA nephropathy patients with celiac autoimmunity compared to those without it (P=0.048 and P=0.022, respectively). The prevalence of celiac autoimmunity seems to be high in patients undergoing renal biopsies, especially in patients with IgA nephropathy. Such autoimmunity may be associated with worse renal function in IgA nephropathy. Hence the co-existence of celiac disease should be taken into consideration when treating patients with renal diseases. Copyright © 2017 Editrice Gastroenterologica Italiana S.r.l.

The aim of this study was to investigate the relationships between personality and joint-specific function, general physical and general mental health in patients undergoing total hip (THA) and knee arthroplasty (TKA). One hundred and eighty-four patients undergoing THA and 205 undergoing TKA were assessed using the Eysneck Personality Questionnaire, brief version (EPQ-BV). General physical and mental health was measured using the Short-Form 12 (SF-12) questionnaire and the EuroQol (EQ-5D). Joint-specific function was measured using the Oxford hip or knee score. The "unstable introvert" personality type was associated with poorer pre-operative function and health in patients with hip arthrosis. In patients with knee arthrosis, there was poorer general health in those with "stable extrovert" and "unstable introvert" types. Personality was not an independent predictor of outcome following TKA or THA. The main predictor was pre-operative function and health. Comorbidity was an important covariate of both pre-operative and postoperative function. Personality may play a role in the interaction of these disease processes with function and health perception. It may also affect the response and interpretation of psychometric and patient-reported outcome measures. It may be important to characterise and identify these traits in potential arthroplasty patients as it may help deliver targeted education and management to improve outcomes in certain groups.

Full Text Available Abstract Background Blood flow in the corpus luteum (CL is closely related to luteal function. It is unclear how luteal blood flow is regulated. Standardized ovarian-stimulation protocol with a gonadotropin-releasing hormone agonist (GnRHa long protocol causes luteal phase defect because it drastically suppresses serum LH levels. Examining luteal blood flow in the patient undergoing GnRHa long protocol may be useful to know whether luteal blood flow is regulated by LH. Methods Twenty-four infertile women undergoing GnRHa long protocol were divided into 3 groups dependent on luteal supports; 9 women were given ethinylestradiol plus norgestrel (Planovar orally throughout the luteal phase (control group; 8 women were given HCG 2,000 IU on days 2 and 4 day after ovulation induction in addition to Planovar (HCG group; 7 women were given vitamin E (600 mg/day orally throughout the luteal phase in addition to Planovar (vitamin E group. Blood flow impedance was measured in each CL during the mid-luteal phase by transvaginal color-pulsed-Doppler-ultrasonography and was expressed as a CL-resistance index (CL-RI. Results Serum LH levels were remarkably suppressed in all the groups. CL-RI in the control group was more than the cutoff value (0.51, and only 2 out of 9 women had CL-RI values Conclusion Patients undergoing GnRHa long protocol had high luteal blood flow impedance with very low serum LH levels. HCG administration improved luteal blood flow impedance. This suggests that luteal blood flow is regulated by LH.

[Hereditary heterozygous factor VII deficiency in patients undergoing surgery : Clinical relevance].

A hereditary deficiency in coagulation factor VII (FVII) may affect the international normalized ratio (INR) value. However, FVII deficiency is occasionally associated with a tendency to bleed spontaneously. We hypothesized that perioperative substitution with coagulation factor concentrates might not be indicated in most patients. In this retrospective data analysis, we included all patients with hereditary heterozygous FVII deficiency who underwent surgical procedures at the University Hospital Basel between December 2010 and November 2015. In addition, by searching the literature, we identified publications reporting patients with FVII deficiency undergoing surgical procedures without perioperative substitution. We identified 22 patients undergoing 46 surgical procedures, resulting in a prevalence of 1:1500-2000. Coagulation factor concentrates were administered during the perioperative period in 15 procedures (33 %), whereas in the other 31 procedures (66 %), FVII deficiency was not substituted. No postoperative bleeding or thromboembolic events were reported. In addition, we found no differences in pre- and postoperative hemoglobin and coagulation parameters, with the exception of an improved postoperative INR value in the substituted group. In the literature review, we identified five publications, including 125 patients with FVII deficiency, undergoing 213 surgical procedures with no perioperative substitution. Preoperative substitution using coagulation factor concentrates does not seem to be mandatory in patients with an FVII level ≥15 %. For decision-making on preoperative substitution, patient history of an increased tendency to bleed may be more important than the FVII level or increased INR value.

HIV testing is currently a major prevention intervention and remains an entry point to early treatment, care and support. Uptake is however low and alternative approaches are currently being adopted. An HIV module was incorporated into the routine survey of the Kintampo Health and Demographic Surveillance System (KHDSS) to assess the willingness of adults living in the Kintampo North and South districts to undergo HIV testing. The study was a descriptive cross-sectional household survey. Univariate and multivariate analysis were used to identify predictors of the willingness to undergo HIV testing. Respondents were community members aged 15 to 49 years and selected from randomly generated household listings from the KHDSS. A total of 11,604 respondents were interviewed, 10,982 (94.6%) of respondents had good general knowledge on HIV/AIDS. Among those with knowledge about HIV/AIDS, 10,819 (98.5%) indicated their willingness to get tested for HIV. Rural residents were more willing to undergo HIV testing than urban dwellers Odds ratio=1.42 (95% Confidence interval: 1.03, 1.96; P-value=0.031). Respondents with primary education were more likely to go for testing relative to those without any education OR=2.02 (95% CI: 0.87, 4.70; P-value=0.046). Expressed willingness to test for HIV is high in this population. Exploring community and population-based interventions to HIV testing and counseling could increase uptake of HIV testing services and should be considered. The underlying motivations need to be explored in order to translate willingness into actual testing.

Patients often resort to religious and spiritual activities to cope with physical and mental challenges. The effect of spiritual coping on overall health, adaptation and health-related quality of life among patients undergoing haemodialysis (HD) is well documented. Thus, it is essential to establish a valid and reliable instrument that can assess both the religious and non-religious coping methods in patients undergoing HD. This study aimed to assess the validity and reliability of the Spiritual Coping Strategies Scale Arabic version (SCS-A) in Saudi patients undergoing HD. A convenience sample of 60 Saudi patients undergoing HD was recruited for this descriptive, cross-sectional study. Data were collected between May and June 2015. Forward-backward translation was used to formulate the SCS-A. The SCS-A, Muslim Religiosity Scale and the Quality of Life Index Dialysis Version III were used to procure the data. Internal consistency reliability, stability reliability, factor analysis and construct validity tests were performed. Analyses were set at the 0.05 level of significance. The SCS-A showed an acceptable internal consistency and strong stability reliability over time. The EFA produced two factors (non-religious and religious coping). Satisfactory construct validity was established by the convergent and divergent validity and known-groups method. The SCS-A is a reliable and valid tool that can be used to measure the religious and non-religious coping strategies of patients undergoing HD in Saudi Arabia and other Muslim and Arabic-speaking countries. © 2016 European Dialysis and Transplant Nurses Association/European Renal Care Association.

Patients undergoing lobectomy are at significantly increased risk of lung injury. One-lung ventilation is the most commonly used technique to maintain ventilation and oxygenation during the operation. It is a challenge to choose an appropriate mechanical ventilation strategy to minimize the lung injury and other adverse clinical outcomes. In order to understand the available evidence, a systematic review was conducted including the following topics: (I) protective ventilation (PV); (II) mode of mechanical ventilation [e.g., volume controlled (VCV) versus pressure controlled (PCV)]; (III) use of therapeutic hypercapnia; (IV) use of alveolar recruitment (open-lung) strategy; (V) pre-and post-operative application of positive end expiratory pressure (PEEP); (VI) Inspired Oxygen concentration; (VII) Non-intubated thoracoscopic lobectomy; and (VIII) adjuvant pharmacologic options. The recommendations of class II are non-intubated thoracoscopic lobectomy may be an alternative to conventional one-lung ventilation in selected patients. The recommendations of class IIa are: (I) Therapeutic hypercapnia to maintain a partial pressure of carbon dioxide at 50–70 mmHg is reasonable for patients undergoing pulmonary lobectomy with one-lung ventilation; (II) PV with a tidal volume of 6 mL/kg and PEEP of 5 cmH2O are reasonable methods, based on current evidence; (III) alveolar recruitment [open lung ventilation (OLV)] may be beneficial in patients undergoing lobectomy with one-lung ventilation; (IV) PCV is recommended over VCV for patients undergoing lung resection; (V) pre- and post-operative CPAP can improve short-term oxygenation in patients undergoing lobectomy with one-lung ventilation; (VI) controlled mechanical ventilation with I:E ratio of 1:1 is reasonable in patients undergoing one-lung ventilation; (VII) use of lowest inspired oxygen concentration to maintain satisfactory arterial oxygen saturation is reasonable based on physiologic principles; (VIII) Adjuvant drugs

Full Text Available Objective: This study aimed to explore the experiences of female breast cancer patients undergoing radiotherapy (RT in a public hospital in Peshawar, Pakistan. Methods: This study employed a descriptive exploratory method. A purposive sample of 14 breast cancer women undergoing RT was selected for this study. Data were collected over the period of 5 months, using a semi-structured interview guide and conducting in-depth face-to-face interviews. These interviews were audio taped and transcribed by a bilingual transcriber. The translated version of the interview was coded, and the analysis was done manually. Results: Four main categories emerged from data analysis, which were: feelings and perceptions of the patients, their challenges, coping strategies, and teaching and informational needs. Conclusions: Women undergoing RT in this culture experience more intense psychological effects, as compared to the physical effects. Keeping in mind, the magnitude of the emotional stress experienced by the participants, recommendations for policy reforms, and training for female RT staff are suggested based on findings of this research.

Diabetes mellitus (DM) and metabolic syndrome are important targets for secondary prevention in cardiovascular disease. However, the prevalence in patients undergoing elective percutaneous coronary intervention is not well defined. We aimed to analyse the prevalence and characteristics of patients undergoing percutaneous coronary intervention with previously unrecognized prediabetes, diabetes and metabolic syndrome. Data were collected from 740 patients undergoing elective percutaneous coronary intervention between November 2010 and March 2013 at a tertiary referral center. Prevalence of DM and prediabetes was evaluated using Haemoglobin A1c (A1c ≥ 6.5% for DM, A1c 5.7-6.4% for prediabetes). A modified definition was used for metabolic syndrome [three or more of the following criteria: body mass index ≥30 kg/m2; triglycerides ≥ 150 mg/dL; high density lipoprotein prediabetes at time of percutaneous coronary intervention. Overall, 54.9% met criteria for metabolic syndrome (69.2% of patients with DM and 45.8% of patients without DM). Among patients undergoing elective percutaneous coronary intervention, a substantial number were identified with a new DM, prediabetes, and/or metabolic syndrome. Routine screening for an abnormal glucometabolic state at the time of revascularization may be useful for identifying patients who may benefit from additional targeting of modifiable risk factors.

Full Text Available OBJECTIVE: The present study was designed to analyze the serum levels of aspartate and alanine aminotransferases, gamma-glutamyl transferase, and the hematocrit in patients with chronic kidney disease who were undergoing peritoneal dialysis or hemodialysis. PATIENTS AND METHODS: Twenty patients on peritoneal dialysis and 40 on hemodialysis were assessed, and the patients were matched according to the length of time that they had been on dialysis. Blood samples were collected (both before and after the session for those on hemodialysis to measure the enzymes and the hematocrit. RESULTS: In the samples from the patients who were undergoing peritoneal dialysis, the aspartate and alanine aminotransferase levels were slightly higher compared with the samples collected from the patients before the hemodialysis session and slightly lower compared with the samples collected after the hemodialysis session. The levels of gamma-glutamyl transferase in the hemodialysis patients were slightly higher than the levels in the patients who were undergoing peritoneal dialysis. In addition, the levels of aminotransferases and gamma-glutamyl transferase that were collected before the hemodialysis session were significantly lower than the values collected after the session. The hematocrit levels were significantly lower in the patients who were on peritoneal dialysis compared with the patients on hemodialysis (both before and after the hemodialysis session, and the levels were also significantly lower before hemodialysis compared with after hemodialysis. CONCLUSION: The aminotransferase levels in the patients who were undergoing peritoneal dialysis were slightly higher compared with the samples collected before the hemodialysis session, whereas the aminotransferase levels were slightly lower compared with the samples collected after the session. The hematocrits and the aminotransferase and gamma-glutamyl transferase levels of the samples collected after the

Renal failure (RF) represents a major postoperative complication for elderly patients undergoing cardiac surgery. This observational cohort study examines effects of preoperative use of renin-angiotensin system (RAS) inhibitors on postoperative renal failure in aging patients undergoing cardiac surgery. We retrospectively analyzed a cohort of 1287 patients who underwent cardiac surgery at this institution (2003-2007). The patients included were ≥65 years old, scheduled for elective cardiac surgery, and without preexisting RF (defined by the criteria of the Society of Thoracic Surgeons as described in Method). Of all patients evaluated, 346 patients met the inclusion criteria and were divided into two groups: using (n = 122) or not using (n = 224) preoperative RAS inhibitors. A comparison of the two groups showed no significant differences in baseline parameters, including creatinine clearance, body mass index, history of diabetes and smoking, preoperative medicines (except that more patients with RAS inhibitors had a history of hypertension or congestive heart failure, fewer RAS inhibitor patients had chronic lung disease), in intraoperative perfusion and aortic cross-clamp time, and in postoperative complications and 30-d mortality. Multivariate logistic regression analysis demonstrated, however, that preoperative RAS inhibitors significantly and independently reduced the incidence of postoperative RF in the patients undergoing cardiac surgery compared with those not taking RAS inhibitors: 1.6% versus 7.6%, yielding an odds ratio of 0.19 (95 % CI 0.04-0.84, P = 0.029). Preoperative RAS inhibitors may have significant renoprotective effects for aging patients undergoing elective cardiac surgery. Copyright © 2011 Elsevier Inc. All rights reserved.

Full Text Available Background. Diarrhea is a common problem in ovarian cancer patients undergoing chemotherapy and Clostridium difficile infection has been identified as a cause. The proper diagnosis and treatment of diarrhea are critical to patient care, especially to prevent the serious complications from a severe Clostridium difficile infection (CDI. Case. We present a heavily pretreated ovarian cancer patient who developed recurrent pseudomembranous colitis while receiving carboplatin chemotherapy. Despite treatment with oral metronidazole for fourteen days, the patient’s diarrhea relapsed and colonoscopy revealed extensive pseudomembranous colitis. The infection eventually resolved with the combination of oral vancomycin and metronidazole. Conclusions. Diarrhea is a common problem in patients undergoing chemotherapy for ovarian cancer. Management requires obtaining the proper diagnosis. Clostridium difficile associated pseudomembranous colitis must be part of the differential diagnosis. Treatment must be sufficient to prevent relapses of the Clostridium difficile infection to prevent serious consequences in an already vulnerable patient population.

Hematopoietic Stem Cell Transplantation in Thalassemia and Sickle Cell Anemia

2012-01-01

The globally widespread single-gene disorders β-thalassemia and sickle cell anemia (SCA) can only be cured by allogeneic hematopoietic stem cell transplantation (HSCT). HSCT treatment of thalassemia has substantially improved over the last two decades, with advancements in preventive strategies, control of transplant-related complications, and preparative regimens. A risk class–based transplantation approach results in disease-free survival probabilities of 90%, 84%, and 78% for class 1, 2, and 3 thalassemia patients, respectively. Because of disease advancement, adult thalassemia patients have a higher risk for transplant-related toxicity and a 65% cure rate. Patients without matched donors could benefit from haploidentical mother-to-child transplantation. There is a high cure rate for children with SCA who receive HSCT following myeloablative conditioning protocols. Novel non-myeloablative transplantation protocols could make HSCT available to adult SCA patients who were previously excluded from allogeneic stem cell transplantation. PMID:22553502

We aimed to determine the radiation doses delivered to patients undergoing general examinations using computed or digital radiography systems in Turkey. Radiographs of 20 patients undergoing posteroanterior chest X-ray and of 20 patients undergoing anteroposterior kidney-ureter-bladder radiography were evaluated in five X-ray rooms at four local hospitals in the Ankara region. Currently, almost all radiology departments in Turkey have switched from conventional radiography systems to computed radiography or digital radiography systems. Patient dose was measured for both systems. The results were compared with published diagnostic reference levels (DRLs) from the European Union and International Atomic Energy Agency. The average entrance surface doses (ESDs) for chest examinations exceeded established international DRLs at two of the X-ray rooms in a hospital with computed radiography. All of the other ESD measurements were approximately equal to or below the DRLs for both examinations in all of the remaining hospitals. Improper adjustment of the exposure parameters, uncalibrated automatic exposure control systems, and failure of the technologists to choose exposure parameters properly were problems we noticed during the study. This study is an initial attempt at establishing local DRL values for digital radiography systems, and will provide a benchmark so that the authorities can establish reference dose levels for diagnostic radiology in Turkey.

Full Text Available Cord blood hematopoietic progenitor cells (CB-HPCs transplanted immunodeficient NOD/LtsZ-scidIL2Rγ(null (NSG and NOD/SCID/IL2Rγ(null (NOG mice need efficient human cell engraftment for long-term HIV-1 replication studies. Total body irradiation (TBI is a classical myeloablation regimen used to improve engraftment levels of human cells in these humanized mice. Some recent reports suggest the use of busulfan as a myeloablation regimen to transplant HPCs in neonatal and adult NSG mice. In the present study, we further ameliorated the busulfan myeloablation regimen with fresh CB-CD34+cell transplantation in 3-4 week old NSG mice. In this CB-CD34+transplanted NSG mice engraftment efficiency of human CD45+cell is over 90% in peripheral blood. Optimal engraftment promoted early and increased CD3+T cell levels, with better lymphoid tissue development and prolonged human cell chimerism over 300 days. These humanized NSG mice have shown long-lasting viremia after HIV-1JRCSF and HIV-1Bal inoculation through intravenous and rectal routes. We also saw a gradual decline of the CD4+T cell count, widespread immune activation, up-regulation of inflammation marker and microbial translocation after HIV-1 infection. Humanized NSG mice reconstituted according to our new protocol produced, moderate cellular and humoral immune responses to HIV-1 postinfection. We believe that NSG mice reconstituted according to our easy to use protocol will provide a better in vivo model for HIV-1 replication and anti-HIV-1 therapy trials.

People's experiences of suffering a lower limb fracture and undergoing surgery.

To describe people's experiences of suffering a lower limb fracture and undergoing surgery, from the time of injury through to the care given at the hospital and recovery following discharge. There is a lack of research on people's experiences of suffering a lower limb fracture and undergoing surgery - from injury to recovery. A qualitative approach was used. Interviews with nine participants were subjected to thematic content analysis. One theme was expressed: from realising the seriousness of the injury to regaining autonomy. Participants described feelings of frustration and helplessness when realising the seriousness of their injury. The wait prior to surgery was a strain and painful experience, and participants needed orientation for the future. They expressed feelings of vulnerability about being in the hands of staff during surgery. After surgery, in the postanaesthesia unit, participants expressed a need to have control and to feel safe in their new situation. To mobilise and regain their autonomy was a struggle, and participants stated that their recovery was extended. Participants found themselves in a new and unexpected situation and experienced pain, vulnerability and a striving for control during the process, that is, 'from realising the seriousness of the injury to regaining autonomy'. How this is managed depends on how the patient's needs are met by nurses. The nursing care received while suffering a lower limb fracture and undergoing surgery should be situation specific as well as individual specific. The safe performance of technical interventions and the nurse's comprehensive explanations of medical terms may help the patient to feel secure during the process. © 2013 John Wiley & Sons Ltd.

To demonstrate the importance of pre-operative ear, nose and throat assessment in patients undergoing endoscopic, transsphenoidal surgery for pituitary tumours. Literature pertaining to the pre-operative otorhinolaryngological assessment and management of patients undergoing endoscopic anterior skull base surgery is sparse. We describe two cases from our series of 59 patients undergoing endoscopic pituitary surgery. The first case involved a young male patient with a large pituitary macroadenoma. His main complaint was visual impairment. He had no previous history of sinonasal pathology and did not complain of any nasal symptoms during the pre-operative neurosurgical assessment. At the time of surgery, a purulent nasal discharge was seen emanating from both middle meati. Surgery was abandoned due to the risk of post-operative meningitis, and postponed until the patient's chronic rhinosinusitis was optimally managed. The second patient was a 47-year-old woman with a large pituitary macroadenoma, who presented to the neurosurgical department with a main complaint of diplopia. She too gave no history of previous nasal problems, and she underwent uneventful surgery using the endoscopic, transnasal approach. Two weeks after surgery, she presented to the emergency unit with severe epistaxis. A previous diagnosis of hereditary haemorrhagic telangiectasia was discovered, and further surgical and medical intervention was required before the epistaxis was finally controlled. Pre-operative otorhinolaryngological assessment is essential prior to endoscopic pituitary or anterior skull base surgery. A thorough otorhinolaryngological history will determine whether any co-morbid diseases exist which could affect the surgical field. Nasal anatomy can be assessed via nasal endoscopy and sinusitis excluded. Computed tomography imaging is a valuable aid to decisions regarding additional procedures needed to optimise access to the pituitary fossa.

The presence of metabolic syndrome in men with prostate cancer (PCa) undergoing androgen-deprivation therapy (ADT), especially intermittent type, has not been completely evaluated. The aim of this study is to evaluate metabolic syndrome in men with PCa undergoing intermittent ADT. In this longitudinal study, we studied the prevalence of metabolic syndrome and its components in 190 patients who were undergoing intermittent ADT. The metabolic syndrome was defined according to the Adult Treatment Panel III criteria. All metabolic parameters, including lipid profile, blood glucose, blood pressures, and waist circumferences of the patients were measured six and 12 months after treatment. Mean age of the patients was 67.5 ± 6.74 years. The incidence of metabolic syndrome after six and 12 months was 6.8% and 14.7%, respectively. Analysis of various components of the metabolic syndrome revealed that patients had significantly higher overall prevalence of hyperglycemia, abdominal obesity, and hypertriglyceridemia in their six- and 12-month followups, but blood pressure has not been changed in the same period except for diastolic blood pressure after six months. Although there was an increased risk of metabolic syndrome in patients receiving intermittent ADT, it was lower than other studies that treated the same patients with continuous ADT. Also it seems that intermittent ADT has less metabolic complications than continuous ADT and could be used as a safe alternative in patients with advanced and metastatic PCa.

Full Text Available Objective: To investigate the etiology of menstrual disorders among patients undergoing hemodialysis due to chronic renal failure by assessing menstrual history, serum hormone levels, and other biochemical factors. Material and methods: Thirty patients undergoing hemodialysis and 30 healthy women at reproductive age were enrolled in our study. Demographic characteristics, hormonal and biochemical data, and sonographically measured endometrial thickness values of the subjects were compared. In addition, the present and the pre-hemodialysis menstrual pattern of the patients undergoing hemodialysis were recorded. The hormonal, hematological, and biochemical data of the patients were compared according to their menstrual patterns. Results: No statistical significance was seen between age, BMI, gravida, parity, abortion, and curettage among groups (p>0.05. Hemoglobin and hematocrit levels were significantly lower in the hemodialysis group than in the control (p0.05. Mean serum LH and prolactin levels were significantly higher in the hemodialysis group compared to the control (p0.05. Serum LH and prolactin levels were higher, and serum FSH, estradiol and TSH levels were lower in patients who developed amenorrhea after hemodialysis treatment when compared to non-amenorrheic subjects. However, these differences were not statistically significant (p>0.05. Discussion: The most important factor in the etiology of menstrual disorders seen in chronic renal failure patients was high serum LH and prolactin levels. Hemodialysis is a successful treatment that extends life expectancy and ameliorates the hypothalamo-pituitary-ovarian axis in chronic renal failure patients.

Abstract The majority of colorectal cancers (CRC) harbor somatic mutations and epigenetic modifications in the tumor tissue, and some of these mutations can be detected in plasma as circulating tumor DNA (ctDNA). Precancerous colorectal lesions also contain many of these same mutations. This study examined plasma for ctDNA from patients undergoing a screening or diagnostic colonoscopy to determine the sensitivity and specificity of the ctDNA panel for detecting CRC and precancerous lesions.

Chronic diseases increase the risk of unemployment even in non-disaster settings; therefore, in post-disaster settings, special attention needs to be paid to the employment status of those suffering from chronic diseases. To examine the association between chronic disease and the risk of unemployment in a disaster area. This cross-sectional study was conducted in Shichigahama Town, Miyagi, north-eastern Japan, where had been severely inundated by the 2011 tsunami. Logistic regression analyses were used to evaluate the association between undergoing medical treatment for a combination of chronic diseases (stroke, cancer, myocardial infarction and angina) and unemployment risk. Confounders such as psychological distress and levels of daily life activity were considered. Among the 2588 individuals studied, there was a statistically significant association between undergoing medical treatment for chronic disease and the risk of unemployment [odds ratio (OR) = 1.7, 95% confidence interval (CI) 1.02-2.7, P unemployment risk was observed only in participants with a higher degree of psychological distress and/or poorer levels of daily life activity. © The Author 2015.

Silvestri, Gerard A; Vincent, Brad D; Wahidi, Momen M

2011-01-01

BACKGROUND: Fospropofol disodium is a water-soluble prodrug of propofol. A subset analysis was undertaken of elderly patients (≥65 y) undergoing flexible bronchoscopy, who were part of a larger multicenter, randomized, double-blind study. METHODS: Patients received fentanyl citrate (50 mcg) followed by fospropofol at initial (4.88mg/kg) and supplemental (1.63mg/kg) doses. The primary end point was sedation success (3 consecutive Modified Observer's Assessment of Alertness/Sedation scores of ≤4 and procedure completion without alternative sedative or assisted ventilation). Treatment success, time to fully alert, patient and physician satisfaction, and safety/tolerability were also evaluated. RESULTS: In the elderly patients subset (n=61), sedation success was 92%, the mean time to fully alert was 8.0±10.9 min, and memory retention was 72% during recovery, and these were comparable with the younger patients subgroup (age, Sedation-related adverse events occurred in 23% of the elderly and 18% of the younger patients (age, sedation, rapid time to fully alert, and high satisfaction in this elderly subset undergoing flexible bronchoscopy, which was comparable with outcomes in younger patients.

Marriage confers various health advantages in the general population. However, the added value of marriage among patients who undergo percutaneous coronary intervention (PCI) beyond the standard cardiovascular risk factors is not clear. This study aimed to assess the effects of marital status on outcomes of patients undergoing elective or urgent PCI. Clinical observational analysis of consecutive patients undergoing elective or urgent PCI from 1993 to 2011 was performed. Patients were stratified by marital status, comparing married to unmarried patients. Clinical outcome up to 12 months was obtained by telephone contact or office visit. A total of 11,216 patients were included in the present analysis; 55% were married and 45% unmarried. Significant differences in baseline characteristics were noted, including a lower prevalence of hypertension (86% vs 88%), diabetes (34% vs 38%), and smoking (19% vs 25%) among married vs unmarried patients, respectively (P married patients had a higher prevalence of hypercholesterolemia and family history of coronary artery disease. Early and late major adverse cardiac event rates were significantly lower for married vs unmarried patients up to 1 year (13.3% vs 8.2%, P Married status was independently associated with improved outcome in multivariable analysis (hazard ratio 0.7, 95% CI 0.6-0.9). Married patients who undergo urgent or elective PCI have superior short- and long-term outcomes up to 1 year when compared with unmarried patients. These benefits persist after adjustment for multiple traditional cardiovascular risk factors. © 2013.

To prevent diseases among children they regularly undergo immunizations. Previous research show different approaches available to facilitate immunization-procedures for children to protect them from harm. To complement this research and provide care suited for children, research recognizing their perceptions of undergoing such a procedure is needed. The aim of this study was to describe 5-year-old children's perceptions of undergoing an immunization. A phenomenographic approach and analysis was used to describe the children's (n = 21) various perceptions. The data-collection was accomplished directly after the immunization to grasp the children's immediate perceptions. Drawings and reflective talks were used as they are considered as suitable methods when involving young children in research. The right to conduct research with children was approved by the appropriate research ethics committee and also by each child and the parents. The findings show that children's perceptions of an immunization-procedure may vary from effortlessly, to manageable or difficult. Regardless of how the child perceive the immunization-procedure each perception embrace the children's descriptions of actors and articles in the situation, their feelings in the situation and also their actions to deal with the immunization. Nevertheless, these descriptions vary according to how the children perceive the immunization as effortlessly, manageable or difficult. Children's and adults' perceptions of medical procedures may differ and children need guidance, time and space to deal with them. Recognizing children's perceptions of undergoing an immunization contributes to the promotion of their right to be involved in their own health care and towards the development of child-centred care. © 2014 Nordic College of Caring Science.

The chronic kidney disease is a major health concern. The number of the elderly people with chronic renal failure has increased across the world. Dialysis is an appropriate therapy for the elderly, but it involves certain challenges. The present paper reports uncertainty as part of the elderly experiences of living with hemodialysis. This qualitative study applied Max van Manen interpretative phenomenological analysis to explain and explore experiences of the elderly with hemodialysis. Given the study inclusion criteria, data were collected using in-depth unstructured interviews with nine elderly undergoing hemodialysis, and then analyzed according to Van Manen 6-stage methodological approach. One of the most important findings emerging in the main study was "uncertainty", which can be important and noteworthy, given other aspects of the elderly life (loneliness, despair, comorbidity of diseases, disability, and mental and psychosocial problems). Uncertainty about the future is the most psychological concerns of people undergoing hemodialysis. The results obtained are indicative of the importance of paying attention to a major aspect in the life of the elderly undergoing hemodialysis, uncertainty. A positive outlook can be created in the elderly through education and increased knowledge about the disease, treatment and complications.

Full Text Available Objective The National Surgical Quality Improvement Program (NSQIP calculator was created to improve outcomes and guide cost-effective care in surgery. Patients with head and neck cancer (HNC undergo ablative and free flap reconstructive surgery with prolonged postoperative courses. Methods A case series with chart review was performed on 50 consecutive patients with HNC undergoing ablative and reconstructive free flap surgery from October 2014 to March 2016 at a tertiary care center. Comorbidities and intraoperative and postoperative variables were collected. Predicted length of stay was tabulated with the NSQIP calculator. Results Thirty-five patients (70% were male. The mean (SD age was 67.2 (13.4 years. The mean (SD length of stay (LOS was 13.5 (10.3 days. The mean (SD NSQIP-predicted LOS was 10.3 (2.2 days ( P = .027. Discussion The NSQIP calculator may be an inadequate predictor for LOS in patients with HNC undergoing free flap surgery. Additional study is necessary to determine the accuracy of this tool in this patient population. Implications for Practice: Head and neck surgeons performing free flap reconstructive surgery following tumor ablation may find that the NSQIP risk calculator underestimates the LOS in this population.

Objective: To determine the frequency and leading factors of pulmonary hypertension among chronic hemodialysis patients. Study Design: Case series. Place and Duration of Study: Hemodialysis Unit, Department of Nephrology, Sindh Institute of Urology and Transplantation, Karachi, from September 2011 to March 2012. Methodology: Patients of either gender aged between 16 to 60 years of age undergoing hemodialysis for at least 3 months not having pre-existing valvular heart disease, chronic lung disease or connective tissue disorder were included. Pulmonary hypertension was prospectively estimated by Doppler echocardiogram on patients undergoing dialysis. Pulmonary artery pressure was calculated on the post-dialysis day and leading factors were compared between patients with and without pulmonary hypertension. Results: A total of 178 patients were included in study with male to female ratio120/58 (2.06:1). The mean age was 33.84 +- 11.9 years. The mean duration of hemodialysis was 23.85 +- 22.48 months. Pulmonary hypertension was found in 76 (42.7%) patients. Out of the studied factors, low serum albumin ( 3.4 mg/dl, p = 0.01) was found to be statistically significant in patients with pulmonary hypertension. Conclusion: Pulmonary hypertension was frequently present in dialysis population (42.7%). This subset of patients had significantly lower albumin levels in serum. More research is needed in its pathogenesis to arrest its course. (author)

This study was conducted to determine the association between the subjective quality of sleep and cognitive decline among the patients of chronic kidney disease (CKD) undergoing haemodialysis. Methods: In this cross-sectional study 106 patients of chronic kidney disease (CKD) undergoing haemodialysis at a tertiary care hospital in Rawalpindi, Pakistan were included in the final analysis. Cognitive decline was measured by British Columbia Cognitive Complaints Inventory (BC-CCI). Sleep quality was measured by using the Pittsburgh Sleep Quality Index (PSQI). Relationship of age, gender, marital status, education, occupation, BMI, duration of dialysis, dialysis count per week, family income, tobacco smoking and use of naswar was assessed with the cognitive decline. Results: Out of 106 patients screened through BC-CCI and PSQI, 13.1% had no cognitive decline while 86.9% had significant cognitive decline. Relationship between quality of sleep and cognitive decline was significant on binary logistic regression. Conclusion: This study showed significant relationship between the sleep quality and cognitive decline among the patients of CKD undergoing haemodialysis. The findings of our study also call for a greater degree of understanding of the physical and psychological state of patients of CKD undergoing haemodialysis. (author)

Aspirin in the Management of Patients with Prostate Cancer Undergoing Radiotherapy: Friend or Foe?

Science.gov (United States)

Mascan, Bianca; Marignol, Laure

2018-04-01

Aspirin has cyclooxygenase-2 (COX2)-mediated anti-inflammatory and anti-coagulant properties that may confer a positive effect in preventing and limiting the progression of prostate cancer. Prostate cancer has been shown to have poor treatment outcomes due to therapeutic resistance; therefore, COX2 inhibition caused by aspirin could represent an opportunity to augment current therapies. This is particularly of interest to patients undergoing radiation therapy (RT) where inflammation is a common side-effect. This review discusses the evidence for the potential role of aspirin in the management of patients with prostate cancer undergoing RT.

Full Text Available Background: Approximately 10% of Iranian couples wishing to have a child experience some types of infertility which may impose a considerable psychological burden on them. The main objective of this cross-sectional study was to examine the level of anxiety and depression among infertile couples undergoing IVF or ICSI treatment cycles in Iran. Methods: Fifty infertile couples that who undergoing IVF (n=25 or ICSI (n=25 cycles were considered for this descriptive cross-sectional study. Also, 25 married couples (18-40 years old with history of fertility served as control subjects. All husbands and wives were examined by means of Beck Depression and Spielberger Anxiety Inventories. Results: Comparing with controls, the highest rates of moderate and severe anxiety, were observed in women undergoing IVF (76% and 12%, respectively; P<0.05. However, the rate of depression among women in IVF group was comparable to women undergoing ICSI. Also, the highest rates of severe depression and anxiety were demonstrated among housewives (23.9% and 11%, respectively. The lowest rates of severe anxiety and depression were observed in husbands participated in either IVF or ICSI cycles. In addition, illiterates, compared with educated couples, undergoing IVF or ICSI program were shown to have the highest rates of both depression and anxiety. Conclusion: The results showed that the levels of anxiety and depression were higher in women, especially housewives, undergoing IVF or ICSI cycles than control subjects. Also, men showed lower rates of anxiety and depression than women undergoing IVF or ICSI. Therefore, this can provide useful information and guidance for health professionals working with infertile patients. KeyWords: anxiety, depression, infertility, IVF, ICSI, Iran

PURPOSE We aimed to determine the radiation doses delivered to patients undergoing general examinations using computed or digital radiography systems in Turkey. MATERIALS AND METHODS Radiographs of 20 patients undergoing posteroanterior chest X-ray and of 20 patients undergoing anteroposterior kidney-ureter-bladder radiography were evaluated in five X-ray rooms at four local hospitals in the Ankara region. Currently, almost all radiology departments in Turkey have switched from conventional radiography systems to computed radiography or digital radiography systems. Patient dose was measured for both systems. The results were compared with published diagnostic reference levels (DRLs) from the European Union and International Atomic Energy Agency. RESULTS The average entrance surface doses (ESDs) for chest examinations exceeded established international DRLs at two of the X-ray rooms in a hospital with computed radiography. All of the other ESD measurements were approximately equal to or below the DRLs for both examinations in all of the remaining hospitals. Improper adjustment of the exposure parameters, uncalibrated automatic exposure control systems, and failure of the technologists to choose exposure parameters properly were problems we noticed during the study. CONCLUSION This study is an initial attempt at establishing local DRL values for digital radiography systems, and will provide a benchmark so that the authorities can establish reference dose levels for diagnostic radiology in Turkey.

Biliary lithiasis is not much frequent in paediatric patients. The manegement of cholelithiasis in patients undergoing laparoscopic cholecystectomy is still controversial. We propose the preoperatory echographic study of the biliary tree 24-48 h before surgery, as the first choice, instead of the intraoperatory cholangiography. We made a retrospective study of 42 patients undergoing laparoscopic cholecystectomy due to symptomatic biliary lithiasis during the last 15 years, with ages between 18 months and 17-years-old (mean age 9,6-years-old) and weight between 11 and 70 kg (mean weight 42 kg) at the moment of surgery. Six of them had haematological illnesses, 17 came to the hospital because of acute abdominal pain, 10 had been studied because of recurrent abdominal pain and 9 had casual diagnoses. Abdominal sonography was performed in all patients 24-48 hours before surgery. Four children were diagnosed of biliary duct lithiasis: two choledocolithiasis and two stones in the cystic duct. One of the cystic stones was extracted in the operating room and the rest resolved spontaneously. One patient presented dilatation of choledocal duct after surgery, without any stones' evidence. Also this patient resolved spontaneously. We had no complications. Biliary lithiasis is not frequent in children, even if it seems to be increasing. A few of these patients will suffer of choledocolithiasis. The intraoperatory exploration of the biliary tree during laparoscopic surgery is technically difficult due the small size of paediatric patients. Cholangiography is not always successful and can produce some important complications as pancreatitis. Preoperative sonography 24-48 hours before surgery is a safe and efficient method for the diagnosis and follow-up of paediatric patients with biliary lithiasis undergoing laparoscopic cholecystectomy. It is safe enough to be performed without intraoperatory cholangiography.

Cardiac manifestations of Marfan syndrome include aortic root dilation and mitral valve prolapse (MVP). Only scant data exist describing MVP in patients with Marfan syndrome undergoing aortic root replacement. We retrospectively analyzed data from 166 MFS patients with MVP who were enrolled in a prospective multicenter registry of patients who underwent aortic root aneurysm repair. Of these 166 patients, 9% had mitral regurgitation (MR) grade >2, and 10% had MR grade 2. The severity of MVP and MR was evaluated by echocardiography preoperatively and ≤ 3 years postoperatively. Forty-one patients (25%) underwent composite graft aortic valve replacement, and 125 patients (75%) underwent aortic valve-sparing procedures; both groups had similar prevalences of MR grade >2 (P=0.7). Thirty-three patients (20%) underwent concomitant mitral valve (MV) intervention (repair, n=29; replacement, n=4), including all 15 patients with MR grade >2. Only 1 patient required MV reintervention during follow-up (mean clinical follow-up, 31 ± 10 months). Echocardiography performed 21 ± 13 months postoperatively revealed MR >2 in only 3 patients (2%). One early death and 2 late deaths occurred. Although the majority of patients with Marfan syndrome who undergo elective aortic root replacement have MVP, only 20% have concomitant MV procedures. These concomitant procedures do not seem to increase operative risk. In patients with MR grade ≤ 2 who do not undergo a concomitant MV procedure, the short-term incidence of progressive MR is low; however, more follow-up is needed to determine whether patients with MVP and MR grade ≤ 2 would benefit from prophylactic MV intervention.

To characterize trends in pain and functional outcomes and identify risk factors in patients with lumbar spinal stenosis (LSS) and neurogenic claudication undergoing the "Minimally Invasive Lumbar Decompression" (MILD) procedure. Retrospective observational cohort study. Academic multidisciplinary pain center at Stony Brook Medicine. Patients undergoing the MILD procedure from October 2010 to November 2012. De-identified perioperative, pain and function related data for 50 patients undergoing MILD were extracted from the Center for Pain Management's quality assessment database. Data included numerical rating scale (NRS), symptom severity and physical function (Zurich Claudication Questionnaire), functional status (Oswestry Disability Index [ODI]), pain interference scores (National Institutes of Health Patient-Reported Outcomes Measurement Information System [PROMIS]), and patients' self-reported low back and lower extremity pain distribution. No MILD patient incurred procedure-related complications. Average NRS scores decreased postoperatively and 64.3% of patients reported less pain at 3 months. Clinically meaningful functional ODI improvements of at least 20% from baseline were present in 25% of the patients at 6 months. Preliminary analysis of changes in PROMIS scores at 3 months revealed that pre-MILD "severe" lumbar canal stenosis may be associated with high risk of "no improvement." No such impact was observed for NRS or ODI outcomes. Overall, pain is reduced and functional status improved in LSS patients following the MILD procedure at 3 and 6 months. Given the small sample size, it is not yet possible to identify patient subgroups at risk for "no improvement." Continued follow-up of longer-term outcomes appears warranted to develop evidence-based patient selection criteria. Wiley Periodicals, Inc.

Cross-sectional study. To investigate the factors associated with work ability in patients undergoing surgery for cervical radiculopathy. Surgery is a common treatment of cervical radiculopathy in people of working age. However, few studies have investigated the impact on the work ability of these patients. Patients undergoing surgery for cervical radiculopathy (n = 201) were recruited from spine centers in Sweden to complete a battery of questionnaires and physical measures the day before surgery. The associations between various individual, psychological, and work-related factors and self-reported work ability were investigated by Spearman rank correlation coefficient, multivariate linear regression, and forward stepwise regression analyses. Factors that were significant (P work ability. Work ability was assessed using the Work Ability Index. The mean Work Ability Index score was 28 (SD, 9.0). The forward stepwise regression analysis revealed 6 factors significantly associated with work ability, which explained 62% of the variance in the Work Ability Index. Factors highly correlated with greater work ability included greater self-efficacy in performing self-cares, lower physical load on the neck at work, greater self-reported chance of being able to work in 6 months' time, greater use of active coping strategies, lower frequency of hand weakness, and higher health-related quality of life. Psychological, work-related and individual factors were significantly associated with work ability in patients undergoing surgery for cervical radiculopathy. High self-efficacy was most associated with greater work ability. Consideration of these factors by surgeons preoperatively may provide optimal return to work outcomes after surgery. 3.

Full Text Available Background & Objectives: Chronic renal failure (CRF, also known as chronic kidney disease, caused by devastated nephron mass of the kidney results in uremia. Hypertension, diabetes mellitus and glomerulonephritis are common etiologic factors of CRF. This condition causes miscellaneous oral manifestations especially in diabetic patients. The aim of this study was to comparison oral manifestations of diabetic and non-diabetic uremic patients undergoing hemodialysis.   Methods: A total of 95 patients who undergoing hemodialysis in Razi hospital in Rasht city participated in this descriptive analytical study. Patients were divided into two diabetic and non- diabetic groups. Oral cavity examinations were done by latex gloves and single use mirror. Objective and subjective oral manifestations such as xerostomia, bad taste, mucosal pain, uremic odor, coating tongue, petechial, purpura, pale oral mucosa, ulcer, dental erosion and candida infection were recorded in questionnaire. After gathering of information, the data were analyzed by SPSS 15 software using t-test and chi square statistical test.   Results: About 60% of patients (57 person were men and 40 % (38 person were women. The mean age of patients was 48 years (range of 20 -76 years. Common subjective oral manifestation in both groups was xerostomia and most common objective oral manifestations were pale oral mucosa, uremic odor and coating tongue respectively. The DMFT index in diabetic group was significantly higher (17.3±7.63 than non-diabetic patients (12.4±8.26. There was no significant statistical correlation between the time of dialysis, number of dialysis appointment during the week and objective and subjective oral manifestations in two groups.   Conclusion: Although, the present study has shown an increase in oral manifestations in diabetic patients undergoing hemodialysis relative to non-diabetic group, but this increase was not statistically significant.

Full Text Available Renal impairment is a well-known risk factor for cardiovascular complications, but the effect of different stages of renal impairment on thrombotic/thromboembolic and bleeding complications in patients with atrial fibrillation (AF undergoing percutaneous coronary intervention (PCI remains largely unknown. We sought to evaluate the incidence and clinical impact of four stages of renal impairment in patients with AF undergoing PCI.We assessed renal function by estimated glomerular filtration rate (eGFR and outcomes in 781 AF patients undergoing PCI by using the data from a prospective European multicenter registry. End-points included all-cause mortality, major adverse cardiac and cerebrovascular events (MACCE and bleeding events at 12 months.A total of 195 (25% patients had normal renal function (eGFR ≥90 mL/min, 290 (37% mild renal impairment (eGFR 60-89, 263 (34% moderate renal impairment (eGFR 30-59 and 33 (4% severe renal impairment (eGFR <30. Degree of renal impairment remained an independent predictor of mortality and MACCE in an adjusted a Cox regression model. Even patients with mild renal impairment had a higher risk of all-cause mortality (HR 2.25, 95%CI 1.02-4.98, p=0.04 and borderline risk for MACCE (HR 1.56, 95%CI 0.98- 2.50, p=0.06 compared to those with normal renal function.Renal impairment is common in patients with AF undergoing PCI and even mild renal impairment has an adverse prognostic effect in these patients requiring multiple antithrombotic medications.

Full Text Available The purpose of this study is to investigate how family-related opinions and stressful situations are related to psychological distress in women undergoing infertility treatment. The subjects in this cross-sectional study were recruited from female patients undergoing infertility treatment (n = 2540 at 70 infertility treatment institutions in Japan. Because of non-participation or missing data, the number of subjects included in the analysis was 635 (response rate, 25.0%. The family-related opinions and stressful situations were evaluated using the original questions. Psychological distress was assessed using a self-report measure, the Kessler Six-question Psychological Distress Scale (K6. The K6 scores of the following participants were significantly (p < 0.05 and independently high: those with more frequent miscarriage/stillbirth/abortions, those with repeated miscarriages as the cause of infertility, those with infertility of unknown causes, those living with no child, those having a low joint income with their partner, those with the opinion that “women should devote themselves to their household duties” those who had considered stopping treatment, those without the opinion that “married life without children is favorable” and those who had experienced stressful situations such as inadequate explanation by doctors, frustration of multiple failed attempts, differences of opinion with the partner, and lack of knowledge regarding when to stop treatment. Family-related opinions and stressful situations associated with psychological distress in women undergoing infertility treatment are outlined. The results of this study may contribute to the prevention of and care for psychological distress in female patients undergoing infertility treatment.

Vascular Platform to Define Hematopoietic Stem Cell Factors and Enhance Regenerative Hematopoiesis

Directory of Open Access Journals (Sweden)

Michael G. Poulos

2015-11-01

Full Text Available Hematopoietic stem cells (HSCs inhabit distinct microenvironments within the adult bone marrow (BM, which govern the delicate balance between HSC quiescence, self-renewal, and differentiation. Previous reports have proposed that HSCs localize to the vascular niche, comprised of endothelium and tightly associated perivascular cells. Herein, we examine the capacity of BM endothelial cells (BMECs to support ex vivo and in vivo hematopoiesis. We demonstrate that AKT1-activated BMECs (BMEC-Akt1 have a unique transcription factor/cytokine profile that supports functional HSCs in lieu of complex serum and cytokine supplementation. Additionally, transplantation of BMEC-Akt1 cells enhanced regenerative hematopoiesis following myeloablative irradiation. These data demonstrate that BMEC-Akt1 cultures can be used as a platform for the discovery of pro-HSC factors and justify the utility of BMECs as a cellular therapy. This technical advance may lead to the development of therapies designed to decrease pancytopenias associated with myeloablative regimens used to treat a wide array of disease states.

Alloreactive regulatory T cells allow the generation of mixed chimerism and transplant tolerance

Directory of Open Access Journals (Sweden)

Paulina eRuiz

2015-11-01

Full Text Available The induction of donor-specific transplant tolerance is one of the main goals of modern immunology. Establishment of a mixed chimerism state in the transplant recipient has proven to be a suitable strategy for the induction of long-term allograft tolerance; however, current experimental recipient preconditioning protocols have many side effects, and are not feasible for use in future therapies. In order to improve the current mixed chimerism induction protocols, we developed a non-myeloablative bone-marrow transplant protocol using retinoic acid induced alloantigen-specific Tregs, clinically available immunosuppressive drugs and lower doses of irradiation. We demonstrate that retinoic acid induced alloantigen-specific Tregs in addition to a non-myeloablative bone-marrow transplant protocol generates stable mixed chimerism and induce tolerance to allogeneic secondary skin allografts in mice. Therefore, the establishment of mixed chimerism through the use of donor-specific Tregs rather than non-specific immunosuppression could have a potential use in organ transplantation.

Kerr Winter, Ben; Odedra, Anand; Green, Steve

Medical tourism, where patients travel abroad intentionally to access medical treatment, is a growing trend. Some of these patients travel to undergo organ transplantation. This study aims to quantify the number of UK patients who undergo liver transplantation abroad, assessing their motivations and management. Questionnaires were sent to all seven UK liver transplant units enquiring about liver patients receiving transplant abroad. Included were questions on destination, motivation, and pre and post-transplant care. Responses were received from six of the seven transplant centres (86%). A total of 12 patients were identified as having undergone liver transplantation overseas. The top destinations were India, China and Egypt. Four units responded to questions regarding pre-transplant screening. One unit reported Hepatitis B and C screening not taking place. Four units responded to questions regarding post-transplant antimicrobial therapy. This revealed examples of patients inappropriately not receiving valganciclovir, co-trimoxazole, anti-fungal treatment and Hepatitis B immunoglobulins. UK patients are undergoing liver transplant abroad, albeit in small numbers. Pre and post-transplant management of these patients is of a lower standard than that provided to those undergoing transplantation in the UK. Information transfer between overseas and UK based transplant teams is poor. Copyright © 2016 Elsevier Ltd. All rights reserved.

To investigate how rewarming impacts the evolution of EEG background in neonates with hypoxic-ischemic encephalopathy (HIE) undergoing therapeutic hypothermia (TH). We recruited a retrospective cohort of 15 consecutive newborns with moderate (9) and severe (6) HIE monitored with a continuous EEG during TH and at least 12h after its end. EEG background was analyzed using conventional visual and quantitative EEG analysis methods including EEG discontinuity, absolute and relative spectral magnitudes. One patient with seizures on rewarming was excluded from analyses. Visual and quantitative analyses demonstrated significant changes in EEG background from pre- to post-rewarming, characterized by an increased EEG discontinuity, more pronounced in newborns with severe compared to moderate HIE. Neonates with moderate HIE also had an increase in the relative magnitude of slower delta and a decrease in higher frequency theta and alpha waves with rewarming. Rewarming affects EEG background in HIE newborns undergoing TH, which may represent a transient adaptive response or reflect an evolving brain injury. EEG background impairment induced by rewarming may represent a biomarker of evolving encephalopathy in HIE newborns undergoing TH and underscores the importance of continuously monitoring the brain health in critically ill neonates.

The Facial Affective Scale as a Predictor for Pain Unpleasantness When Children Undergo Immunizations

Directory of Open Access Journals (Sweden)

Stefan Nilsson

2014-01-01

Full Text Available Needle fear is a common problem in children undergoing immunization. To ensure that the individual child’s needs are met during a painful procedure it would be beneficial to be able to predict whether there is a need for extra support. The self-reporting instrument facial affective scale (FAS could have potential for this purpose. The aim of this study was to evaluate whether the FAS can predict pain unpleasantness in girls undergoing immunization. Girls, aged 11-12 years, reported their expected pain unpleasantness on the FAS at least two weeks before and then experienced pain unpleasantness immediately before each vaccination. The experienced pain unpleasantness during the vaccination was also reported immediately after each immunization. The level of anxiety was similarly assessed during each vaccination and supplemented with stress measures in relation to the procedure in order to assess and evaluate concurrent validity. The results show that the FAS is valid to predict pain unpleasantness in 11-12-year-old girls who undergo immunizations and that it has the potential to be a feasible instrument to identify children who are in need of extra support to cope with immunization. In conclusion, the FAS measurement can facilitate caring interventions.

The purpose of this qualitative descriptive study was to explore hemodialysis patients' family members' understanding of end-of-life decision-making processes. The project aimed to address (a) family members' constructions of advance care planning (ACP), including their roles and responsibilities, and (b) family members' perceptions of health care providers' roles and responsibilities in ACP. Eighteen family members of persons undergoing hemodialysis were recruited primarily from outpatient dialysis facilities and interviewed individually. Confirmed transcript data were analyzed, coded, and compared, and categories were established. Interpretations were validated throughout the interviews and peer debriefing sessions were used at a later stage in the analysis. The overarching construct identified was one of Protection. Family members protect patients by (a) Sharing Burdens, (b) Normalizing Life, and (c) Personalizing Care. Recommendations for future research include the need to explore ACP of persons undergoing hemodialysis who do not have a family support system. © The Author(s) 2013.

The objective of this study was to compare the postoperative analgesic effects of dexketoprofen, tramadol, and buprenorphine in dogs undergoing ovariohysterectomy. Seventy-five adult female dogs were randomly assigned to receive an intravenous injection (IV) of 1mg/kg of dexketoprofen (D), 0.02 mg/kg of buprenorphine (B) or 2mg/kg of tramadol (T). Pain assessment was performed during 48 h after ovariohysterectomy using a dynamic interactive visual analogue scale (DIVAS) and Glasgow composite measure pain scale (CMPS-SF). Rescue analgesia was required in 43%, 21%, and 5% of dogs in the B, T, and D groups, respectively, with significant differences between B and D (p=0.010) groups. The DIVAS and CMPS-SF values of the B group were significantly higher than those of the T and D groups. The most common undesirable effect was dysphoria in dexketoprofen group. Tramadol and dexketoprofen provide superior postoperative analgesia compared with buprenorphine in dogs undergoing ovariohysterectomy. Copyright © 2013 Elsevier Ltd. All rights reserved.

Full Text Available Human papilloma virus (HPV is related to respiratory mucosal diseases, such as recurrent respiratory papillomatosis, as well as to upper-respiratory-tract malignancies. There are few reports concerning the prevalence of HPV in the upper respiratory tract of non-affected individuals. We examined the prevalence of HPV in the tonsils of children of the general population scheduled for tonsillectomy. Samples were taken from the tonsils of 100 children undergoing tonsillectomy and were then tested for HPV with the polymerase chain reaction (PCR technique, utilizing the generic primers MY09 and MY 11. The study excluded children known to have HPV and HIV-related diseases. Parents and legal guardians completed a standardized socio-demographic questionnaire. The questionnaire revealed that 84% of the mothers had at least one risk factor for genital HPV. None of the tonsil samples were positive for HPV. Apparently HPV does not commonly colonize the tonsils of children undergoing routine tonsillectomy.

Attention-deficit/hyperactivity disorder (ADHD) is the most common childhood psychiatric disorder. This disorder is more prevalent in some chronic disease. The aim of this study was to investigate ADHD in children with end-stage renal disease (ESRD) undergoing continuous ambulatory peritoneal dialysis (CAPD) and to compare the results with those of healthy children. This case-control study was conducted for six months (December 22, 2013 to June 21, 2014) on five to 16-year-old children, visiting the Pediatric Dialysis Unit of Amirkabir Hospital, Arak, Iran, and Taleghani Hospital, Kermanshah, Iran. A total of 100 children with ESRD who had undergone CAPD for at least six months and 100 healthy children were included in this study as case and control groups, respectively. ADHD was diagnosed by Conner's Parent Rating Scale-48 (CPRS-48) and DSM-IV-TR criteria, and was confirmed through consultation by psychologist. Data were analyzed by Binomial test in SPSS 18. The ADHD inattentive type was observed in 16 cases (16%) with CAPD and five controls (5%) (P = 0.01). Moreover, ADHD hyperactive-impulsive type was observed in 27 cases (27%) with CAPD and seven controls (9%) (P = 0.002). Despite these significant differences, no children were diagnosed with ADHD combined type among all subjects. Inattentive type and hyperactive-impulsive type of ADHD are more prevalent in children with ESRD undergoing CAPD. Therefore screening methods for ADHD is necessary in these patients.

2015-09-01

Full Text Available The incidence and prevalence of cardiovascular disease (CVD are increasing rapidly in developing countries. Most patients with CVD do not respond to medical treatment and have to undergo cardiac surgery. This highly stressful experience results in increased levels of anxiety for patients. The objective of this review was to evaluate the efficacy of massage therapy on postoperative outcomes among patients undergoing cardiac surgery. A comprehensive literature search was made on PubMed-Medline, CINAHL, Science Direct, Scopus, Web of Science and the Cochrane library databases for original research articles published between 2000 and 2015. Original articles that reported the efficacy of massage therapy in patients undergoing cardiac surgery were included. The Cochrane data extraction form was used to extract data. A total of 297 studies were identified in the literature search. However, only seven studies were eligible for analysis. Of the seven studies, six studies demonstrated the effects of massage therapy on improving post-operative outcomes of patients, while one study found no evidence of improvement. Although the methods varied considerably, most of the studies included in this review reported positive results. Therefore, there is some evidence that massage therapy can lead to positive postoperative outcomes. Evidence of the effectiveness of massage therapy in patients undergoing cardiac surgery remains inconclusive. Additional research is needed to provide a strong evidence base for the use of massage therapy to improve post-operative outcomes and recovery among cardiac surgery patients

The purpose of this study was to detect Streptococcus mutans by using monoclonal antibodies (mAbs) against S. mutans that cause dental caries and compare the levels of the bacterium between the saliva of adolescents undergoing orthodontic treatment (OT) and those not undergoing treatment (NT). Saliva samples, collected from 25 OT adolescents (with a mean age of 12.84 years) and 25 NT adolescents (mean age of 12.4 years), were analyzed by Dentocult-SM and enzyme-linked immunosorbent assay using mAbs against Ag I/II (ckAg I/II) and GTF B (ckGTF B), GTF C (ckGTF C), and GTF D (ckGTF D) of S. mutans. The DMFT index was slightly higher in the OT group (5.12 in OT and 4.96 in NT) and the level of S. mutans (≥10 5 CFU/mL) was higher in OT (72%) than in NT (56%). The detected levels of ckAg I/II, ckGTF B, ckGTF C, and ckGTF D were slightly higher in OT than in NT. The results of this study indicate that use of mAbs against S. mutans yields sensitive detection for the bacterium in saliva samples and shows that it has a reliable connection to the number of S. mutans and decayed, missing, filled teeth (DMFT), suggesting that the levels of S. mutans in saliva can be defined and compared by the application of the mAbs.

The objective was to identify risk factors associated with blood transfusion in patients undergoing high-order Cesarean delivery (CD). This was a retrospective cohort study of patients undergoing third or more CD by a single maternal-fetal medicine practice between 2005 and 2016. We compared risk factors between women who did and did not receive a red blood cell transfusion during the operation or before discharge. Repeat analysis was performed after excluding women with placenta previa. A total of 514 patients were included, 18 of whom (3.5%; 95% confidence interval [CI], 2.2%-5.5%) received a blood transfusion. Placenta previa was the most significant risk factor for transfusion (61.1% of patients who received a transfusion vs. 1% of patients who did not; p blood transfusion. After women who had placenta previa were excluded, the incidence of blood transfusion was seven of 498 (1.4%; 95% CI, 0.7%-2.9%). Risk factors significantly associated with blood transfusion in the absence of previa were prophylactic anticoagulation during pregnancy and having labored. The incidence of transfusion in patients with no placenta previa, no anticoagulation, and no labor was 0.7% (95% CI, 0.3%-2.1%). Placenta previa was the most predictive risk factor for transfusion with a positive predictive value of 68.8% and a negative predictive value of 98.4%.

Gonad shielding has been advocated to reduce radiation exposure in patients undergoing pelvic radiography. The aim of this study is to evaluate the frequency and accuracy of gonad shield placement in patients undergoing pelvic radiography. A retrospective study was performed on 1230 anteroposterior (AP) pelvic radiographs of 939 children under 16 years old. All the radiographs were reviewed to determine the frequency of gonad shielding and to evaluate whether gonad shields were correctly positioned when they are used. The gonad shield was present in 82 radiographs (30 girls and 52 boys) and was completely disregarded in 1148 radiographs. From 82 images which shield was present, the gonad shields adequately positioned in 28 radiographs (3 girls and 25 boys) and in the remaining 54 radiographs, the shield did not adequately protected the gonads due to incorrect placement of the shield. The inaccuracy placement and absence of gonad shields were more common in girls than boys (P-value < 0.05). More care should be taken to correctly positioning of the gonad shields in boys and its usage should be encouraged. However, the practice of ovarian shielding is not an effective way to reduce radiation exposure in girls undergoing pelvis radiography. (author)

In solid triphenylmethanol, the molecules are arranged in hydrogen-bonded tetramers, and it is already well established that the hydrogen bonding in this material undergoes a dynamic switching process between different hydrogen bonding arrangements. In addition to this motion, we show here, from solid-state 2 H NMR studies of the deuterated material (C 6 D 5 ) 3 COH, that each phenyl ring in this material undergoes a 180 deg.-jump reorientation about the C 6 D 5 -C(OH) bond, with an activation energy of ca. 50 kJ mol -1 . The timescale for the phenyl ring dynamics is several orders of magnitude longer than the timescale for the hydrogen bond dynamics in this material, and is uncorrelated with the dynamics of the hydrogen bonding arrangement

Nasogastric intubation causes gastroesophageal reflux in patients undergoing elective laparotomy.

Manning, B J

2012-02-03

BACKGROUND: The routine use of nasogastric tubes in patients undergoing elective abdominal operation is associated with an increased incidence of postoperative fever, atelectasis, and pneumonia. Previous studies have shown that nasogastric tubes have no significant effect on the incidence of gastroesophageal reflux or on lower esophageal sphincter pressure in healthy volunteers. We hypothesized that nasogastric intubation in patients undergoing laparotomy reduces lower esophageal sphincter pressure and promotes gastroesophageal reflux in the perioperative period. METHODS: A prospective randomized case-control study was undertaken in which 15 consenting patients, admitted electively for bowel surgery, were randomized into 2 groups. Group 1 underwent nasogastric intubation after induction of anesthesia, and Group 2 did not. All patients had manometry and pH probes placed with the aid of endoscopic vision at the lower esophageal sphincter and distal esophagus, respectively. Nasogastric tubes, where present, were left on free drainage, and sphincter pressures and pH were recorded continuously during a 24-hour period. Data were analyzed with 1-way analysis of variance. RESULTS: The mean number of reflux episodes (defined as pH < 4) in the nasogastric tube group was 137 compared with a median of 8 episodes in the group managed without nasogastric tubes (P =.006). The median duration of the longest episode of reflux was 132 minutes in Group 1 and 1 minute in Group 2 (P =.001). A mean of 13.3 episodes of reflux lasted longer than 5 minutes in Group 1, with pH less than 4 for 37.4% of the 24 hours. This was in contrast to Group 2 where a mean of 0.13 episodes lasted longer than 5 minutes (P =.001) and pH less than 4 for 0.2% of total time (P =.001). The mean lower esophageal sphincter pressures were lower in Group 1. CONCLUSIONS. These findings demonstrate that patients undergoing elective laparotomy with routine nasogastric tube placement have significant gastroesophageal

The pharmacokinetics of flomoxef (FMOX), an oxacephem antibiotic, were investigated in pediatric patients undergoing chronic hemodialysis. The results are summarized as follows. 1. FMOX was given intravenously in a single dose of 10 mg/kg to 5 pediatric patients (ranging from 7 to 15 years of age) undergoing chronic hemodialysis. It was also given in a dose of 5 mg/kg to 2 of these patients. Its concentrations in serum and urine were determined using bioassay. Pharmacokinetic analyses were performed using a two compartment open model. 2. The serum concentrations of FMOX, administered in doses of 10 mg/kg or 5 mg/kg on non-hemodialysis days, were 33.3 +/- 4.09 micrograms/ml (mean +/- standard deviation) and 17.6 micrograms/ml (mean) at 30 minutes after injection, 29.6 +/- 3.51 micrograms/ml and 15.9 micrograms/ml at 1 hour, 27.2 +/- 2.14 micrograms/ml and 15.1 micrograms/ml at 2 hours, 23.5 +/- 1.90 micrograms/ml and 13.0 micrograms/ml at 4 hours, 20.8 +/- 2.44 micrograms/ml and 12.2 micrograms/ml at 6 hours, 18.9 +/- 1.86 micrograms/ml and 11.0 micrograms/ml at 8 hours, and 9.64 +/- 1.43 micrograms/ml and 6.16 micrograms/ml at 24 hours, respectively. 3. The urinary concentrations of FMOX, administered in a dose of 10 mg/kg, were 42.4-123 micrograms/ml between 0-6 hours after injection, 14.1-52.5 micrograms/ml between 6-24 hours, and 2.86-23.7 micrograms/ml between 24-48 hours. The urinary excretion rate in the first 48 hours after injection ranged from 9.1 to 10.5%.(ABSTRACT TRUNCATED AT 250 WORDS)

Full Text Available Abstract Background Psychiatric comorbidity is common in back pain patients undergoing disc surgery and increases economic costs in many areas of health. The objective of this study was to analyse psychiatric comorbidity as predictor of direct and indirect costs in back pain patients undergoing disc surgery in a longitudinal study design. Methods A sample of 531 back pain patients was interviewed after an initial disc surgery (T0, 3 months (T1 and 15 months (T2 using the Composite International Diagnostic Interview to assess psychiatric comorbidity and a modified version of the Client Sociodemographic and Service Receipt Inventory to assess resource utilization and lost productivity for a 3-month period prior interview. Health care utilization was monetarily valued by unit costs and productivity by labour costs. Costs were analysed using random coefficient models and bootstrap techniques. Results Psychiatric comorbidity was associated with significantly (p  Conclusion Psychiatric comorbidity presents an important predictor of direct and indirect costs in back pain patients undergoing disc surgery, even if patients do not utilize mental health care. This effect seems to be stable over time. More attention should be given to psychiatric comorbidity and cost-effective treatments should be applied to treat psychiatric comorbidity in back pain patients undergoing disc surgery to reduce health care utilization and costs associated with psychiatric comorbidity.

Preformed donor-specific human leukocyte antigen antibodies (DSAs) in patients undergoing simultaneous liver and kidney transplantation (SLKT) are an independent risk factor for poorer patient and renal allograft survival. The outcomes of patients highly sensitized (HS) against HLA antigens undergoing SLKT and select HS SLKT recipients undergoing desensitization at a high-volume desensitization center were investigated. Seventy-five patients undergoing SLKT at a high-volume desensitization center between January 1, 2001, and December 31, 2015, were retrospectively reviewed. HS patients were defined by panel-reactive antibody (PRA) >30% (n = 17 patients), 11 of whom received pre- or perioperative desensitization with high-dose intravenous immunoglobulin (IVIG) ± rituximab. HS patients had significantly higher class I and class II PRA (class I = 41.3% ± 40.0% vs 2.5% ± 6.3%; class II = 45.7% ± 36.4% vs 1.0% ± 2.9%; P Desensitization in select HS SLKT patients was well tolerated but did not improve patient and allograft survival or significantly curtail rejection. HS SLKT recipients demonstrated increased allograft rejection, particularly CMR, but patient and graft survival were not impacted in the first year post-transplant. Select HS SLKT patients tolerated desensitization with high-dose IVIG ± rituximab and may have received additional immunoprotection against ABMR but survival was not affected.

Glomerular filtration rate (GFR) is partially impaired in patients with multiple sclerosis (MS). When given chemotherapy before receiving hematopoietic stem-cell transplantation, GFR might be further deteriorated. To measure the effect of cyclophosphamide on GFR in patients with MS who undergo chemotherapy. We estimated GFR based on creatinine and cystatin C plasma concentrations in patients undergoing autologous hematopoietic stem-cell transplantation to treat their MS. Baseline GFR values were lower in the 28 patients with MS than in the 20 healthy individuals. Also, according to the Chronic Kidney Disease-Epidemiology Collaborative Group (CKD-EPI) 2012 Creat-CysC equation criteria, 4 of 28 patients were classified as having chronic kidney disease (CKD) before receiving the chemotherapy drugs. After receiving 4 × 50 mg per kg body weight cyclophosphamide, abnormal GFR results were recorded in 12 of 28 patients. Renal function must be monitored in patients with MS undergoing autologous stem-cell transplantation. Also, chemotherapy should be constrained as much as possible to prevent further deterioration of renal function.

Objective: Anxiety and stress are common in patients undergoing invasive procedures. Coronary angiography is a definitive diagnostic evaluation for coronary artery disease and valvular disease. It is necessary to give information to the patients in order to minimize levels of anxiety and stress to this invasive procedure. The aim of this study was to evaluate the effect of patients education by video on levels of anxiety, stress and depression of patients undergoing coronary angiography. Methodology: In a quasi-experimental, pretest-posttest design, 128 patients were randomly assigned to either control or experimental group. Control group received verbal routine education by nurses and experimental group received an informative video about coronary angiography procedure as well as pre and post angiography interventions. Using Depression, Anxiety, Stress Scale (DASS-21) levels of these variables were measured before and after education. Results: Seventy eight (60.9%) males and fifty (39.1%) females participated in the study. There was a statistically significant reduction in the Anxiety, stress and depression levels of experimental group after video information (P = .000). There was a statistically significant correlation between sex with anxiety (P = .000) and stress (P = .04). Conclusions: The use of patients education by informative video is a useful method for decreasing psychological parameters of patients undergoing coronary angiography procedure. Results of the study confirm the usefulness of video information prior to an Invasive angiography procedure. (author)

Full Text Available BACKGROUND The present study is to find out the prevalence of CAD in severe Aortic Stenosis (AS patients undergoing aortic valve replacement and the relation between the conventional risk factors and CAD in them. Calcific aortic stenosis is associated with the same risk factors as coronary artery disease. Studies on calcific aortic stenosis and CAD are rarely reported from India. The aim of the study is to find out the predictive value of angina for presence of CAD in severe aortic stenosis. MATERIALS AND METHODS All cases of isolated severe aortic stenosis undergoing CAG before aortic valve replacement were included in the study. Data regarding various risk factors, symptoms, echocardiographic parameters and angiographic profile were collected. RESULTS Among a total of 94 patients who have undergone aortic valve replacement for severe AS 40 (42.6% had CAD. Risk factors like advanced age, hypertension, diabetes and smoking were more in patients with CAD compared to isolate AS. Mean gradient was more in the AS + CAD group compared with AS group. Presence of angina had a sensitivity of 82.5% and specificity of 51.85% for predicting coexisting CAD. CONCLUSION Among severe aortic stenosis, patients undergoing AVR 42.6% of patients had significant obstructive CAD. The conventional risk factors predict presence of coronary artery disease. Angina has got a fairly good sensitivity, but moderate specificity for CAD.

Despite major advances in pain management, cancer pain is managed poorly in 80% of the patients with cancer. Due to deleterious side effects of pharmacology therapy in these people, there is an urgent need for clinical trials of non-pharmacological interventions. To examine the effect of therapeutic touch (TT) on the pain and fatigue of the cancer patients undergoing chemotherapy, a randomized and three-groups experimental study—experimental (TT), placebo (placebo TT), and control (usual care)—was carried out. Ninety patients undergoing chemotherapy, exhibiting pain and fatigue of cancer, were randomized into one of the three groups in the Cancer Center of Imam Khomeini Hospital in Tehran, Iran. Pain and fatigue were measured and recorded by participants before and after the intervention for 5 days (once a day). The intervention consisted of 30 min TT given once a day for 5 days between 10:00 a.m. and 10:30 a.m. The Visual Analogue Scale (VAS) of pain and the Rhoten Fatigue Scale (RFS) were completed for 5 days before and after the intervention by the subjects. The TT (significant) was more effective in decreasing pain and fatigue of the cancer patients undergoing chemotherapy than the usual care group, while the placebo group indicated a decreasing trend in pain and fatigue scores compared with the usual care group.

We instituted a ketamine-predominant analgesic regimen in the peri- and postoperative periods to limit the effects of narcotic analgesia on bowel function in patients undergoing radical cystectomy. The primary end points of interest were time to return of bowel function, time to discharge, and efficacy of the analgesic regimen. We performed a retrospective chart review of patients undergoing robotic-assisted laparoscopic cystectomy (RARC) with urinary diversion by a single surgeon at our institution from January 1, 2011 to June 30, 2012. Patients receiving the opioid-minimizing ketamine protocol were compared to a cohort of patients undergoing RARC with an opioid-predominant analgesic regimen. In total, 15 patients (Group A) were included in the ketamine-predominant regimen and 25 patients (Group B) in the opioid-predominant control group. Three patients (19%) in Group A discontinued the protocol due to ketamine side effects. The mean time to bowel movement and length of stay in Group A versus Group B was 3 versus 6 days (p return of bowel function and length of hospitalization after RARC. Our study has its limitations as a retrospective, single surgeon, single institution study and the non-randomization of patients. Notwithstanding these limitations, this study was not designed to show inferiority of one approach, but instead to show that our protocol is safe and efficacious, warranting further study in a prospective fashion.

To compare postoperative outcomes in children undergoing cardiac surgery during the viral respiratory season and nonviral season at our institution. This was a retrospective cohort study and secondary matched case-control analysis. The setting was an urban academic tertiary-care children's hospital. The study was comprised of all patients <18 years of age who underwent cardiac surgery at Johns Hopkins Hospital from October 2002 through September 2007. Patients were stratified by season of surgery, complexity of cardiac disease, and presence or absence of viral respiratory infection. Measurements included patient characteristics and postoperative outcomes. The primary outcome was postoperative length of stay (LOS). A total of 744 patients were included in the analysis. There was no difference in baseline characteristics or outcomes, specifically, no difference in postoperative LOS, intensive care unit (ICU) LOS, and mortality, among patients by seasons of surgery. Patients with viral respiratory illness were more likely to have longer postoperative LOS (p < 0.01) and ICU LOS (p < 0.01) compared with matched controls. We identified no difference in postoperative outcomes based on season in patients undergoing cardiac surgery. Children with viral respiratory infection have significantly worse outcomes than matched controls, strengthening the call for universal administration of influenza vaccination and palivizumab to appropriate groups. Preoperative testing for respiratory viruses should be considered during the winter months for children undergoing elective cardiac surgery.

About 85,000 patients have undergone replacement of diseased heart valves with prosthetic Björk-Shiley convexo-concave (CC) valves. These valves are prone to fracture of the outlet strut, which leads to acute valve failure that is usually fatal. Should patients with these valves undergo prophylactic replacement to avoid fracture? The incidence of strut fracture varies between 0% and 1.5% per year, depending on valve opening angle (60 degrees or 70 degrees), diameter (less than 29 mm or greater than or equal to 29 mm), and location (aortic or mitral). Other factors include the patient's life expectancy and the expected morbidity and mortality associated with reoperation. We have used decision analysis to identify the patients most likely to benefit from prophylactic reoperation. The incidence of outlet strut fracture was estimated from the data of three large studies on CC valves, and stratified by opening angle, diameter, and location. A Markov decision analysis model was used to estimate life expectancy for patients undergoing prophylactic valve replacement and for those not undergoing reoperation. Prophylactic valve replacement does not benefit patients with CC valves that have low strut fracture risks (60 degrees aortic valves and less than 29 mm, 60 degrees mitral valves). For most patients with CC valves that have high strut fracture risks (greater than or equal to 29 mm, 70 degrees CC), prophylactic valve replacement increases life expectancy. However, elderly patients with such valves benefit from prophylactic reoperation only if the risk of operative mortality is low. Patient age and operative risk are most important in recommendations for patients with CC valves that have intermediate strut fracture risks (less than 29 mm, 70 degrees valves and greater than or equal to 29 mm, 60 degrees mitral valves). For all patients and their doctors facing the difficult decision on whether to replace CC valves, individual estimates of operative mortality risk that

As life expectancy increases, it is expected that 60% of all cases of cancer will be detected in elderly patients in the next two decades. Cancer treatment for older persons is complicated by a number of factors, thus negatively affecting patients' quality of life. The purpose of this study is to investigate quality of life in elderly cancer patients undergoing chemotherapy. This study was descriptive and non-experimental. It was conducted in one large hospital in a major city of Northern Greece. The sample was convenience comprising 53 elderly cancer patients undergoing cycle 3 chemotherapy. The data was collected using the Functional Assessment of Cancer Therapy scale and included questions related to demographic and clinical characteristics. The majority of participants were men (n = 27, 50.9%) who were married (n = 32, 79.5%). Their mean age was 70.07 ± 3.60. Almost half of the sample (n = 30, 56.6%) had colon cancer. There was a statistical significant difference between men and women pertaining to physical wellbeing (p = 0.004) and overall quality of life (p family wellbeing (p = 0.029), functional wellbeing (p = 0.09) and overall quality of life (p family wellbeing (p = 0.029). These findings call attention to quality of life and its related factors in elderly cancer patients. It is highly recommended to envisage measures for improving quality of life in this group of cancer patients.

Full Text Available BACKGROUND Breast Cancer is the most common female cancer worldwide and carries significant psychosocial morbidity. The diagnosis of the disease and the treatment modalities like surgery and chemotherapy contribute to the morbidity. The recognition of the psychosocial morbidity associated with mastectomy can help us formulate effective counselling strategies. The objectives of this study were- to assess the psychosocial morbidity in patients undergoing mastectomy for carcinoma breast, to identify the preoperative variables that predict the morbidity and to find out the correlation between degree of neuroticism of the individual and morbidity. MATERIALS AND METHODS 35 female patients who had mastectomy for breast cancer were evaluated at three time-points, preoperatively, immediately after surgery and 2 months after surgery. Anxiety and depression was assessed using Hospital Anxiety and Depression Scale (HADS, psychological distress was measured using General Health Questionnaire (GHQ-12 and neuroticism was assessed by Eysenck Personality Inventory Neuroticism subscale (EPI-N. RESULTS There was a high level of anxiety, depression and GHQ scores preoperatively with a further worsening of these over the three interviews. Age, marital status and menopausal status were factors which had an influence on psychosocial morbidity. Preoperative EPI-N scores positively correlated with psychosocial morbidity. CONCLUSION There is a high level of psychosocial morbidity in patients undergoing mastectomy for breast cancer and mastectomy seems to worsen it in the first two months after surgery. Our study shows that psychosocial morbidity is affected by age, marital status, menopausal status and level of neuroticism.

A nonaffine network model for elastomers undergoing finite deformations

Davidson, Jacob D.; Goulbourne, N. C.

2013-08-01

In this work, we construct a new physics-based model of rubber elasticity to capture the strain softening, strain hardening, and deformation-state dependent response of rubber materials undergoing finite deformations. This model is unique in its ability to capture large-stretch mechanical behavior with parameters that are connected to the polymer chemistry and can also be easily identified with the important characteristics of the macroscopic stress-stretch response. The microscopic picture consists of two components: a crosslinked network of Langevin chains and an entangled network with chains confined to a nonaffine tube. These represent, respectively, changes in entropy due to thermally averaged chain conformations and changes in entropy due to the magnitude of these conformational fluctuations. A simple analytical form for the strain energy density is obtained using Rubinstein and Panyukov's single-chain description of network behavior. The model only depends on three parameters that together define the initial modulus, extent of strain softening, and the onset of strain hardening. Fits to large stretch data for natural rubber, silicone rubber, VHB 4905 (polyacrylate rubber), and b186 rubber (a carbon black-filled rubber) are presented, and a comparison is made with other similar constitutive models of large-stretch rubber elasticity. We demonstrate that the proposed model provides a complete description of elastomers undergoing large deformations for different applied loading configurations. Moreover, since the strain energy is obtained using a clear set of physical assumptions, this model may be tested and used to interpret the results of computer simulation and experiments on polymers of known microscopic structure.

Objectives To determine whether nonselective preoperative carotid artery ultrasound screening alters management of patients scheduled for coronary artery bypass grafting (CABG), and whether such screening affects neurologic outcomes. Methods From March 2011 to September 2013, preoperative carotid artery ultrasound screening was performed on 1236 of 1382 patients (89%) scheduled to undergo CABG. Carotid artery stenosis (CAS) was classified as none or mild (any type 0%–59% stenosis), moderate (unilateral 60%-79% stenosis), or severe (bilateral 60%-79% stenosis or unilateral 80%–100% stenosis). Results A total of 1069 (86%) hadundergoing CABG + CEA and 3 of 148 (2.0%) undergoing CABG alone experienced stroke (P = .4). In patients with moderate CAS, stroke occurred in 1 of 11 (9.1%) off-pump and 1 of 79 (1.3%) on-pump patients (P = .2). In patients with severe CAS, stroke occurred in 1 of 6 (17%) off-pump and 1 of 71 (1.4%) on-pump patients (P = .15). Conclusions Routine preoperative carotid artery evaluation altered the management of a minority of patients undergoing CABG; this did not translate into perioperative stroke risk. Hence, a more targeted approach for preoperative carotid artery evaluation should be adopted. PMID:26586360

Each exercise session was conducted as follows: initial cardiovascular activity (6-12 min, followed by stretching (5-10 min, resistance training (15-30 min, and a cool-down (approximately 8 min. Significant changes in TCI were observed among groups (F1,18 = 8.582; P = 0.009, at treatments 2 and 3, and at the end of the study [experimental (1973 ± 419, control (1488 ± 418; experimental (1946 ± 437, control (1436 ± 429; experimental (2315 ± 455, control (1474 ± 294, respectively]. A significant negative correlation was found (Spearman rho(18 = -0.759; P < 0.001 between TCI and %BF and between TCI and fatigue levels (Spearman rho(18 = -0.541; P = 0.014 at the end of the study. In conclusion, the results of this study suggest that an exercise intervention administered to breast cancer patients undergoing medical treatment may assist in the mitigation of some treatment side effects, including decreased TCI, increased fatigue, and negative changes in body composition.

Stereotactic ablative body radiotherapy (SABR) is an emerging treatment technique for pulmonary metastases in which conventional Response Evaluation Criteria in Solid Tumours (RECIST) may be inadequate. This study aims to assess the utility of CT perfusion imaging in response assessment of pulmonary metastases after SABR. In this ethics board-approved prospective study, 11 patients underwent a 26-Gy single fraction of SABR to pulmonary metastases. CT perfusion imaging occurred prior to and at 14 and 70 days post-SABR. Blood flow (mL/100 mL/min), blood volume (mL/100 mL), time to peak (seconds) and surface permeability (mL/100 mL/min), perfusion parameters of pulmonary metastases undergoing SABR, were independently assessed by two radiologists. Inter-observer variability was analysed. CT perfusion results were analysed for early response assessment comparing day 14 with baseline scans and for late response by comparing day 70 with baseline scans. The largest diameter of the pulmonary metastases undergoing SABR was recorded. Ten patients completed all three scans and one patient had baseline and early response assessment CT perfusion scans only. There was strong level of inter-observer agreement of CT perfusion interpretation with a median intraclass coefficient of 0.87 (range 0.20–0.98). Changes in all four perfusion parameters and tumour sizes were not statistically significant. CT perfusion imaging of pulmonary metastases is a highly reproducible imaging technique that may provide additional response assessment information above that of conventional RECIST, and it warrants further study in a larger cohort of patients undergoing SABR.

While transradial approach to conduct percutaneous coronary interventions offers multiple advantages, the procedure can cause radial artery damage and occlusion. Because radial artery is the preferred site for the creation of an arteriovenous fistula to provide dialysis, patients with chronic kidney disease are particularly dependent on radial artery for their long-term survival. In this retrospective study, we investigated the prevalence of chronic kidney disease in patients undergoing coronary interventions via radial artery. Stage of chronic kidney disease was based on estimated glomerular filtration rate and National Kidney Foundation - Kidney Disease Outcomes Quality Initiative guidelines. A total of 497 patients undergoing transradial percutaneous coronary interventions were included. Over 70.4% (350/497) of the patients had chronic kidney disease. Stage II chronic kidney disease was observed in 243 (69%) patients (estimated glomerular filtration rate = 76.0 ± 8.4 mL/min). Stage III was observed in 93 (27%) patients (estimated glomerular filtration rate = 49 ± 7.5 mL/min). Stage IV chronic kidney disease was observed in 5 (1%) patients (estimated glomerular filtration rate = 25.6 ± 4.3 mL/min) and Stage V chronic kidney disease was observed in 9 (3%) patients (estimated glomerular filtration rate = 9.3 ± 3.5 mL/min). Overall, 107 of 350 patients (30%) had advanced chronic kidney disease, that is, stage III-V chronic kidney disease. Importantly, 14 of the 107 (13%) patients had either stage IV or V chronic kidney disease. This study finds that nearly one-third of the patients undergoing transradial percutaneous coronary interventions have advanced chronic kidney disease. Because many of these patients may require dialysis, the use of radial artery to conduct percutaneous coronary interventions must be carefully considered in chronic kidney disease population.

Full Text Available SUMMARY Introduction: the EuroSCORE II and STS are the most used scores for surgical risk stratification and indication of transcatheter aortic valve implantation (TAVI. However, its role as a tool for mortality prediction in patients undergoing TAVI is still unclear. Objective: to evaluate the performance of the EuroSCORE II and STS as predictors of in-hospital and 30-day mortality in patients undergoing TAVI. Methods: we included 59 symptomatic patients with severe aortic stenosis that underwent TAVI between 2010 and 2014. The variables were analyzed using Student's t-test and Fisher's exact test and the discriminative power was evaluated using receiver operating characteristic curve (ROC and area under the curve (AUC with a 95% confidence interval. Results: mean age was 81±7.3 years, 42.3% men. The mean EuroSCORE II was 7.6±7.3 % and STS was 20.7±10.3%. Transfemoral procedure was performed in 88.13%, transapical in 3.38% and transaortic in 8.47%. In-hospital mortality was 10.1% and 30-day mortality was 13.5%. Patients who died had EuroSCORE II and STS higher than the survivors (33.7±16.7vs. 18.6±7.3% p=0,0001 for STS and 13.9±16.1 vs. 4.8±3.8% p=0.0007 for EuroSCORE II. The STS showed an AUC of 0.81 and the EuroSCORE II of 0.77 and there were no differences in the discrimination ability using ROC curves (p=0.72. Conclusion: in this cohort, the STS and EuroSCORE II were predictors of in-hospital and 30-days mortality in patients with severe aortic stenosis undergoing TAVI.

Little is known about the prevalence of nonalcoholic fatty liver disease (NAFLD) among severely obese adolescents or factors that determine its development. We investigated the prevalence of NAFLD in a multicenter cohort of adolescents undergoing bariatric surgery and the factors associated with it. We enrolled 242 adolescents undergoing bariatric surgery between March 2007 and February 2012 at 5 tertiary care centers into a multicenter, prospective observational cohort study. Intraoperative core liver biopsies were collected from 165 subjects; 17 were excluded because of insufficient liver tissue or use of hepatotoxic medications, so 148 remained in the study (mean age, 16.8 ± 1.6 years; median body mass index = 52 kg/m(2)). Liver tissues were analyzed by histology using validated criteria. Hepatic gene expression was analyzed in 67 samples. NAFLD was present in 59% of this predominantly female (72%), white (68%), non-Hispanic (91%) cohort. Of subjects with NAFLD, 24% had borderline and 10% had definite nonalcoholic steatohepatitis (NASH). Mild fibrosis (stage 2 or lower) was observed in 18% of liver biopsies and stage 3 was observed in 0.7%, but cirrhosis was not detected. Dyslipidemia was present in 78% of subjects, hypertension in 44%, and diabetes in 14%. More severe NAFLD was associated with increasing levels of alanine aminotransferase, fasting glucose level, hypertension (each P adolescents undergoing bariatric surgery in this cohort had NAFLD, yet the prevalence of severe or fibrotic NASH was low. Increasing severity of NAFLD was associated with level of alanine aminotransferase and cardiometabolic risk factors, but not body mass index. Based on gene expression analysis, borderline and definite NASH were associated with abnormal immune function, intestinal cholesterol absorption, and lipid metabolism. Copyright © 2015 AGA Institute.

Ansari, M.R.; Modani, H.

2008-01-01

The purpose of this study was to evaluate the conjunctival bacterial flora and its antibiotic susceptibility pattern in eyes of patients undergoing cataract surgery. Conjunctival soap was obtained on the day of surgery before the application of topical anesthetic, antibiotic or povidone-iodine. Culture and antibiotic susceptibility tests were performed. The data was analysed with X/sup 2/ and T tests. Of the 170 patients 89 cases (52.4%) had positive cultures in the eyes. In 79 eyes (88.8%) found coagulase-negative Staphylococcus (CoNS). Eighty two cases (95.3%) of isolated Staphylococcus were susceptible to Amikacin, 86 (100%) sensitive to Ciprofloxacin and 42 (48.8%) sensitive to Ceftazidime. Average susceptibility and resistancy to antibiotics was 2.6 (+-1.8) antibiotics in women and 1.6(+-1.4) in men (P= 0.009). This study showed that the bacterium most frequently found in the conjunctival flora of the patients undergoing cataract surgery was CoNS. Isolates of this bacterium had low CoNS susceptibility rates to Caftazidime and Vancomycin and high susceptibility to Ciprofloxacin and Amikacin. (author)

Purpose: Ultrasound-guided trans perineal interstitial permanent prostate brachytherapy (TIPPB) is generally performed with either 103 Pd or 125 I. The use of 125 I for low Gleason score tumors and 103 Pd for higher Gleason scores has been suggested based on isotope dose rate and cell doubling time observed in in vitro studies. While many centers follow these isotope selection criteria, other centers have elected to use only a single isotope, regardless of Gleason score. No clinical data have been published comparing these isotopes. This study was undertaken to compare outcomes between 125 I and 103 Pd in a matched pair analysis for patients undergoing prostate brachytherapy. Methods and Materials: Six hundred forty-eight consecutively treated patients with clinically confined prostate cancer underwent TIPPB between June 1992 and February 1997. Five hundred thirty-two patients underwent TIPPB alone, whereas 116 received pelvic external beam irradiation and TIPPB. Ninety-three patients received androgen deprivation therapy prior to TIPPB. The prescribed doses for TIPPB were 160 Gy for 125 I (pre-TG43) and 120 Gy for 103 Pd. Patients treated with combination therapy received 41.4 or 45 Gy (1.8 Gy/fraction) external beam irradiation followed by a 3- to 5-week break and then received either a 120-Gy 125 I or a 90-Gy 103 Pd implant. Until November 1994, all patients underwent an 125 I implant after which the isotope selection was based on either Gleason score (Gleason score 2-5: 125 I; Gleason 5-8: 103 Pd) or isotope availability. A matched pair analysis was performed to assess any difference between isotopes. Two hundred twenty-two patients were matched according to Gleason score, prostate-specific antigen (PSA), and stage. PSA relapse-free survival (PSA-RFS) was calculated based on the American Society for Therapeutic Radiology and Oncology (ASTRO) Consensus Group definition of failure. Kaplan-Meier actuarial survival curves were compared to assess differences in

This study was aimed at assessing the effectiveness and the importance of an oral hygiene (OH) protocol in patients undergoing radiation therapy and chemotherapy after prosthesis rehabilitation, in order to reduce or minimize oral complications. This study was carried out at the Department of Dental Science, at the University of Bari-Italy from December 2012 to December 2015 on 34 selected patients with primary oral cancer undergoing chemotherapy and radiotherapy after prosthesis rehabilitation. They were divided into 2 groups according to their age, sex and cancer therapy. Seventeen patients were assigned to the control group and seventeen in the experimental one. In the experimental group (Table 1), patients underwent an oral hygiene protocol whereas in the control group (Table 2) patients received the usual care provided within the clinical setting. All the patients gave written informed consent. It has been asked and obtained the authorisation from the Ethics Committee of the Dental Science and Surgery Department. Results show that in patients undergoing the oral hygiene protocol, the complications and the risks of infection and permanent dental problems have been minimized. Indeed, of the seventeen patients undergoing the OH protocol, 70% obtained positive results and were satisfied with the program outcome. The role of the health care providers is essential to educate patients to adhere to the prescribed treatments and reinforce their motivation in oral hygiene. The oral hygiene procedures prevent and ameliorate oral complications due to the radiation therapy and chemotherapy.

Children with cancer often undergo a long course of treatment, described as painful, and associated with feelings of discomfort and need of comfort. The aim of this descriptive interview study was to investigate how children, aged 3 to 9 years, undergoing cancer treatment describe their experience of comfort. The children were interviewed and asked to make drawings. Data were content analyzed and four themes were constructed--enduring discomfort, expressing discomfort, finding comfort, and comforting others. The findings show that the children endured discomfort during treatment, and were sometimes able to express it. They found comfort especially from their family and from hospital staff. The children also described that they comforted family members. The findings are in accordance with previous research about children's and adults' accounts of comfort. An incidental finding is that parents were surprised when they listened to the children's accounts of their experience of discomfort and comfort and achieved a better understanding of their children.

Objective The aim of this study was to investigate the association among gingival enlargement (GE), periodontal conditions and socio-demographic characteristics in subjects undergoing fixed orthodontic treatment. Methods A sample of 330 patients undergoing fixed orthodontic treatment for at least 6 months were examined by a single calibrated examiner for plaque and gingival indexes, probing pocket depth, clinical attachment loss and gingival enlargement. Socio-economic background, orthodontic treatment duration and use of dental floss were assessed by oral interviews. Associations were assessed by means of unadjusted and adjusted Poisson's regression models. Results The presence of gingival bleeding (RR 1.01; 95% CI 1.00-1.01) and excess resin around brackets (RR 1.02; 95% CI 1.02-1.03) were associated with an increase in GE. No associations were found between socio-demographic characteristics and GE. Conclusion Proximal anterior gingival bleeding and excess resin around brackets are associated with higher levels of anterior gingival enlargement in subjects under orthodontic treatment.

Full Text Available We evaluated 752 patients for endometriosis in consecutive laparoscopic procedures over a one year period. Six hundred eighty patients underwent laparoscopy for indications unrelated to symptoms of endometriosis and 72 patients were diagnosed clinically to have endometriosis before the procedures. In the 72 patients with clinical indications of endometriosis, 59 patients had disease confirmed at surgery (82%. Out of 680 asymptomatic patients, 186 patients (24.7% were documented to have the disease of various characteristics or appearances in which the typical lesions accounted for 42%. The overall prevalence among these women undergoing laparoscopy was 32.5%. However, a prevalence of 12% was shown in a subset of asymptomatic patients indicated for sterilization. This may reflect the appropriate prevalence in reproductive age population.

Salivary gland tumors are mostly benign tumors. Whether a more conservative surgical approach at greater risk of recurrence, or a more radical intervention with an increased risk of facial paralysis is warranted is still under discussion. Our study addresses the opportunity for improving surgical outcome by employing platelet-rich plasma (PRP) gel at the surgical site. Twenty consecutive patients undergoing superficial parotidectomy were randomized and assigned to two groups, one with and one without PRP gel. Many parameters were evaluated after surgery and during follow-up, such as the duration of hospitalization, facial nerve deficit, onset of Frey's syndrome, relapse, cosmetic results, presence of keloid or scar depressions, behavior of several facial muscles. Our explorative analysis suggests a positive effect of PRP on surgical outcome in patients undergoing parotidectomy, whereas no negative effects were detected. This work suggests that administration of PRP in patients undergoing parotidectomy is beneficial.

It has been previously demonstrated that T lymphocytes may be involved in the development of hypertension and microvascular remodeling, and that circulating T effector lymphocytes may be increased in hypertension. In particular, Th1 and Th 17 lymphocytes may contribute to the progression of hypertension and microvascular damage while T-regulatory (Treg) lymphocytes seem to be protective in this regard. However, no data is available about patients with severe obesity, in which pronounced microvascular alterations were observed. We have investigated 32 severely obese patients undergoing bariatric surgery, as well as 24 normotensive lean subjects and 12 hypertensive lean subjects undergoing an elective surgical intervention. A peripheral blood sample was obtained before surgery for assessment of CD4+ T lymphocyte subpopulations. Lymphocyte phenotype was evaluated by flow cytometry in order to assess T-effector and Treg lymphocytes. A marked reduction of several Treg subpopulations was observed in obese patients compared with controls, together with an increased in CD4+ effector memory T-effector cells. In severely obese patients, Treg lymphocytes are clearly reduced and CD4+ effector memory cells are increased. It may be hypothesized that they might contribute to the development of marked microvascular alterations previously observed in these patients.

This study was carried out on wholebody radiation dose assessment to paediatrics patient who undergo PET/CT scanner at Institut Kanser Negara. Consist of 68 patients with varies of malignancies and epilepsy disease case covering age between 2 years to 12 years old. This is a retrospective study from 2010-2014. The use of PET/CT scanner as an advanced tool has been proven to give an extra radiation dose to the patient. It is because of the radiation exposure from the combination of both CT and PET scans rather than a single CT or PET scan. Furthermore, a study on radiation dose to paediatric patient undergoing PET/CT is rare in Malaysia. So, the aim of this study is to estimate the wholebody effective dose to paediatric patient in Malaysia. Effective dose from PET scan was calculated based on the activity of F18 FDG and dose coefficient reported in International Commission on Radiological Protection (ICRP) Publication 106. Effective dose from CT was determined using k coefficient as reported in ICRP publication 102 and Dose Length Product (DLP) value. The average effective dose from PET and CT were found to be 7.05mSv and 5.77mSv respectively. The mean wholebody effective dose received by a patient with combined PETCT examination was 12.78mSv. These results could be used as reference for dosimetry of a patient undergoing PETCT examination in Malaysia.

The aim of this study is to compare the hemodynamic effects of neostigmine-atropine combination and sugammadex in patients with cardiac problems undergoing noncardiac surgery. Prospective randomized study. In the operating room. Ninety patients with a class 2 or 3 cardiovascular disease according to the New York Heart Association classification and aged between 18 and 75 years undergoing noncardiac surgery were randomized. Group N (n = 45) received 0.03 mg/kg IV neostigmine when T2 appeared as measured with a nerve muscle stimulator. When heart rate was 5 beats/min (±10 beats/min) lower than the heart rate before administration of the medication, 0.5 mg IV atropine sulfate was given. Group S (n = 45) received 3 mg/kg IV sugammadex when T2 appeared as measured with a nerve muscle stimulator. Heart rate, mean systolic and diastolic blood pressures, and electrocardiographic alterations including the QTc (QT Fredericia and QT Bazett) were recorded. There were no significant differences between and within the groups in terms of QTc values. Sugammadex group had a significant decrease on heart rate 1 minute after the medication when compared to the measurement before the medication (P Sugammadex group had lower systolic, diastolic, and mean blood pressures and heart rate when compared to neostigmine group (P sugammadex might be preferred as it provides more hemodynamic stability compared to neostigmine-atropine combination to reverse rocuronium-induced neuromuscular blockage in cardiac patients undergoing noncardiac surgery.

Infertility affects both women and men in the physical, emotional, existential, and interpersonal realms. When couples seek in vitro fertilisation (IVF) treatment, they further suffer from the difficulties of the treatment and the uncertainty of its outcome. The aim of this study was to develop a preliminary conceptual framework for couples undergoing IVF treatment to give health professionals a better understanding of the experiences of such couples, and to guide the development of an intervention. The process of identifying frameworks adopted in intervention studies confirmed that there is no established framework for infertile couples undergoing IVF treatment. A skeletal framework identified from previous studies provides an internal structure for the proposed framework for couples undergoing IVF treatment, filled out with concepts drawn from a concept analysis and a qualitative study, knitting the structure together. This preliminary framework is the Endurance with Partnership Conceptual Framework (P-EPCF). It consists of four domains: the impacts of infertility and stressors, dyadic mediators, dyadic moderators and dyadic outcomes. According to the P-EPCF, the impacts of infertility and IVF treatment can be mediated by the couples' partnership and dyadic coping. Improvements in the psychological well-being and marital functioning of IVF couples can then be expected. The P-EPCF would be potentially valuable in guiding the development of a complex, couple-based intervention, which could focus on enhancing the partnership of couples and their coping strategies.

The saliva of patients undergoing orthodontic treatment with fixed appliances can potentially present a delay in the diluting, clearing, and buffering of dietary acids due to an increased number of retention areas. The aim of this clinical trial was to compare salivary pH kinetics of patients with and without orthodontic treatment, following the intake of an acidic beverage. Twenty participants undergoing orthodontic treatment and 20 control counterparts had their saliva assessed for flow rate, pH, and buffering capacity. There was no significant difference between salivary parameters in participants with or without an orthodontic appliance. Salivary pH recovery following acidic beverage intake was slower in the orthodontic subjects compared to controls. Patients with fixed orthodontic appliances, therefore, seem to be at higher risk of dental erosion, suggesting that dietary advice and preventive care need to be implemented during orthodontic treatment.

We investigated the effect of high spinal anesthesia on postoperative delirium in opium dependent patients undergoing coronary artery bypass grafting (CABG). The study was conducted in a tertiary referral university hospital on a population of 60 opium dependent patients undergoing CABG surgery. Patients were divided into two groups based on anesthesia protocol. One group were given general anesthesia (GA Group), the other group additionally received intrathecal morphine and bupivacaine (SGA Group). Postoperative delirium (POD) was defined as the main outcome of interest. Incidence of POD was significantly higher in patients of GA Group as compared with those in SGA Group (47% and 17% for GA and SGA respectively; P-value = 0.01). Time to extubation was on average 2.2 h shorter in SGA than in GA (7.1 h and 9.3 h respectively, P-value opium dependent patients.

Long-Term-Monitoring (LTM) is a valuable tool for seizure localization/lateralization among children with refractory-epilepsy undergoing pre-surgical-monitoring. The aim of this study was to examine the factors predicting occurrence of single/multiple seizures in children undergoing pre-surgical monitoring in the LTM unit. Chart review was done on 95 consecutive admissions on 92 children (40 females) admitted to the LTM-unit for pre-surgical workup. Relationship between occurrence of multiple (≥ 3) seizures and factors such as home seizure-frequency, demographics, MRI-lesions/seizure-type and localization/AED usage/neurological-exam/epilepsy-duration was evaluated by logistic-regression and survival-analysis. Home seizure-frequency was further categorized into low (up-to 1/month), medium (up-to 1/week) and high (>1/week) and relationship of these categories to the occurrence of multiple seizures was evaluated. Mean length of stay was 5.24 days in all 3 groups. Home seizure frequency was the only factor predicting the occurrence of single/multiple seizures in children undergoing presurgical workup. Other factors (age/sex/MRI-lesions/seizure-type and localization/AED-usage/neurological-exam/epilepsy-duration) did not affect occurrence of single/multiple seizures or time-to-occurrence of first/second seizure. Analysis of the home-seizure frequency categories revealed that 98% admissions in high-frequency, 94% in the medium, and 77% in low-frequency group had at-least 1 seizure recorded during the monitoring. Odds of first-seizure increased in high vs. low-frequency group (p=0.01). Eighty-nine percent admissions in high-frequency, 78% in medium frequency, versus 50% in low-frequency group had ≥ 3 seizures. The odds of having ≥ 3 seizures increased in high-frequency (p=0.0005) and in medium-frequency (p=0.007), compared to low-frequency group. Mean time-to-first-seizure was 2.7 days in low-frequency, 2.1 days in medium, and 2 days in high-frequency group. Time

Introduction: Quality of life is an important topic in the study of chronic diseases, especially cancer which can have a major effect on patient self-confidence. This study was conducted to determine quality of life and its relationship with self-confidence in women undergoing treatment for breast cancer. Methods: This cross-sectional, descriptive, analytical study was conducted in 2016 on 166 women with breast cancer undergoing treatment at Ghazi, Al-Zahra, International and/or Shams hospitals in Tabriz. The subjects were selected through convenience sampling. A personal-demographic questionnaire, the Cancer Quality of Life Questionnaire (QLQ-C30), and the Rosenberg Self-Esteem Scale (RSES) were completed for each patient. The data obtained were analyzed using independent t-tests, one-way ANOVA, multivariate linear regression and Pearson’s correlation coefficients. Findings: The mean total score of quality of life was 59.1±17.4, ranging from 0 to 100. The highest mean score was obtained in the cognitive subscale (74.9±23.8) and the lowest in the emotional subscale (51.4±21.1). The mean score for self-confidence was 0.3 with a standard deviation of 0.1, ranging from -1 to +1. There was a significant positive relationship between self-confidence and quality of life, except in three symptom subscales for diarrhea, constipation and loss of appetite (Pquality of life. Discussion: Given the significant relationship between quality of life and self-confidence, health care providers may need to pay special attention to women undergoing treatment for breast cancer and perform timely measures to maintain their belief in themselves.

Highlights: ► Coffee residue, sawdust and rice husk undergoing torrefaction are investigated. ► A high-volatile bituminous coal and a low-volatile one are also regarded for comparison. ► Coffee residue is the most active biomass to torrefaction. ► Torrefied wastes approach the high-volatile coal as increasing temperature and duration. ► Torrefaction is conducive to the applications of biomass in industrial furnaces. -- Abstract: Three agricultural wastes, consisting of coffee residue, sawdust and rice husk, undergoing torrefaction are investigated to evaluate the potential of biomass as solid fuel. Two different torrefaction temperatures (240 and 270 °C) and durations (0.5 and 1 h) are considered in the study, and the properties and structures of the raw and torrefied wastes are extensively investigated by means of proximate, elemental, fiber, calorific, thermogravimetric, SEM and FTIR analyses. A high-volatile bituminous coal and a low-volatile one are also regarded for comparison. By virtue of more hemicellulose contained in the coffee residue, it is the most active biomass to torrefaction and its higher heating value (HHV) is improved up to 38%. The empirical atomic formula of the raw wastes is expressed by CH 1.54–1.76 O 0.65–0.89 and it changes to CH 1.02–1.57 O 0.26–0.64 after undergoing torrefaction. The torrefied biomasses approach high-volatile coal when the torrefaction temperature and duration increase. From fuel point of view, the improved properties and changed molecular structure are conducive to the applications of biomass in industrial furnaces such as boilers and blast furnaces.

Approximately 300 children, from 0 to 18 years old, are diagnosed with cancer in Sweden every year. Of these children, 80–90 of them undergo radiotherapy treatment for their cancer. Although radiotherapy is an encounter with advanced technology, few studies have investigated the child’s and the parent’s view of the procedure. As part of an ongoing multicenter study aimed to improve patient preparation and the care environment in pediatric radiotherapy, this article reports the findings from interviews with parents at baseline. The aim of the present study was twofold: to describe parents’ experience when their child undergoes radiotherapy treatment, and to report parents’ suggestions for improvements during radiotherapy for their children. Sixteen mothers and sixteen fathers of children between 2–16 years old with various cancer diagnoses were interviewed. Data were analyzed using content analysis. The findings showed that cancer and treatment turns people’s lives upside down, affecting the entire family. Further, the parents experience the child’s suffering and must cope with intense feelings. Radiotherapy treatment includes preparation by skilled and empathetic staff. The parents gradually find that they can deal with the process; and lastly, parents have suggestions for improvements during the radiotherapy treatment. An overarching theme emerged: that despair gradually turns to a sense of security, with a sustained focus on and close interaction with the child. In conclusion, an extreme burden was experienced around the start of radiotherapy, though parents gradually coped with the process. PMID:26509449

Reduction of cognitive function is a possible side effect after cardiac surgery using cardiopulmonary bypass. We investigated the cerebroprotective effect of piracetam on cognitive performance in patients undergoing coronary artery bypass surgery under cardiopulmonary bypass. Patients scheduled for elective, primary and isolated coronary bypass surgery were randomised either to piracetam or placebo group. The study was performed in a double blind fashion. Patients received either 12 g piracetam or placebo at the beginning of the operation. Six neuropsychological subtests from the Syndrom Kurz Test and the Alzheimer's Disease Assessment Scale were performed preoperatively and on the third postoperative day. To assess the overall cognitive function and the degree of cognitive decline across all tests after surgery we combined the six test-scores by principal component analysis. A total number of 120 patients were enrolled into the study. Preoperative overall cognitive function were not significantly different between the groups. The postoperative combined score of the neuropsychological tests showed a deterioration of cognitive function in both groups (placebo-pre: -0.06+/-0.99 vs placebo-post: -1.38+/-1.11; ppiracetam-pre: 0.06+/-1.02 vs piracetam-post: -0.65+/-0.93; ppiracetam patients performed significantly better compared to the placebo patients after the operation and had a less decline of overall cognitive function (pPiracetam has a cerebroprotective effect in patients undergoing coronary artery bypass surgery with the use of cardiopulmonary bypass. It reduces an early postoperative substantial decline of neuropsychological abilities.

It is a growing trend that patients seek health information on the internet to self-educate and self-diagnose, which impacts their health decisions. The aim of the study was to investigate how Chinese patients undergoing elective laparoscopic cholecystectomy (LC) sought information about their disease and treatment, how they preferred the information to be presented, and how it influenced them. A descriptive, cross-sectional-designed questionnaire was employed to obtain information from 248 Chinese patients undergoing elective LC in Peking Union Medical College Hospital. A total of 223 patients (89.9 %) sought health information from the internet. Patients searching the internet for information about LC were younger than those who did not. It varied with employment status, educational level, and household average income. Among patients searching the internet for LC information, 35.4 % felt more worried and 37.2 % felt more assured; 15.2 % went to visit other doctors and 8.5 % considered changing their treatment because of internet use. A significant proportion of patients used the internet to obtain information about their disease. Age, employment status, educational level, and household average monthly income had an effect on internet usage for LC information. The use of the internet could cause mixed emotional outcomes among patients. Physicians should guide Chinese patients to professional websites of high quality and take time to discuss the information with patients during their visits and consultations.

We present the experimental observation and theoretical analysis of fluid flow in acoustically levitated water drop undergoing sectorial oscillations. The fluid always flows between the extended sections and the compressed sections. The magnitude of fluid velocity decreases from the equatorial fringe to the centre of levitated drop. The maximum fluid velocity is 60-160 mm/s and the Reynolds number of the oscillations is estimated to be 137-367. The internal flow of the drop is analyzed as potential flow, and the fluid velocity is found to be horizontal. In the equatorial plane, the calculated stream lines and velocity profiles agree well with the experimental observations.

Background People with atrial fibrillation (AF) often undergo cardiac surgery for other underlying reasons and are frequently offered concomitant AF surgery to reduce the frequency of short- and long-term AF and improve short- and long-term outcomes. Objectives To assess the effects of concomitant AF surgery among people with AF who are undergoing cardiac surgery on short-term and long-term (12 months or greater) health-related outcomes, health-related quality of life, and costs. Search methods Starting from the year when the first “maze” AF surgery was reported (1987), we searched the Cochrane Central Register of Controlled Trials (CENTRAL) in the Cochrane Library (March 2016), MEDLINE Ovid (March 2016), Embase Ovid (March 2016), Web of Science (March 2016), the Database of Abstracts of Reviews of Effects (DARE, April 2015), and Health Technology Assessment Database (HTA, March 2016). We searched trial registers in April 2016. We used no language restrictions. Selection criteria We included randomised controlled trials evaluating the effect of any concomitant AF surgery compared with no AF surgery among adults with preoperative AF, regardless of symptoms, who were undergoing cardiac surgery for another indication. Data collection and analysis Two review authors independently selected studies and extracted data. We evaluated the risk of bias using the Cochrane ‘Risk of bias’ tool. We included outcome data on all-cause and cardiovascular-specific mortality, freedom from atrial fibrillation, flutter, or tachycardia off antiarrhythmic medications, as measured by patient electrocardiographic monitoring greater than three months after the procedure, procedural safety, 30-day rehospitalisation, need for post-discharge direct current cardioversion, health-related quality of life, and direct costs. We calculated risk ratios (RR) for dichotomous data with 95% confidence intervals (CI) using a fixed-effect model when heterogeneity was low (I2 ≤ 50%) and random

Importance of tissue perfusion in ST segment elevation myocardial infarction patients undergoing reperfusion strategies: role of adenosine.

Science.gov (United States)

Forman, Mervyn B; Jackson, Edwin K

2007-11-01

High risk ST segment elevation myocardial infarction (STEMI) patients undergoing reperfusion therapy continue to exhibit significant morbidity and mortality due in part to myocardial reperfusion injury. Importantly, preclinical studies demonstrate that progressive microcirculatory failure (the "no-reflow" phenomenon) contributes significantly to myocardial reperfusion injury. Diagnostic techniques to measure tissue perfusion have validated this concept in humans, and it is now clear that abnormal tissue perfusion occurs frequently in STEMI patients undergoing reperfusion therapy. Moreover, because tissue perfusion correlates poorly with epicardial blood flow (TIMI flow grade), clinical studies show that tissue perfusion is an independent predictor of early and late mortality in STEMI patients and is associated with infarct size, ventricular function, CHF and ventricular arrhythmias. The mechanisms responsible for abnormal tissue perfusion are multifactorial and include both mechanical obstruction and vasoconstrictor humoral factors. Adenosine, an endogenous nucleoside, maintains microcirculatory flow following reperfusion by activating four well-characterized extracellular receptors. Because activation of adenosine receptors attenuates the mechanical and functional mechanisms leading to the "no reflow" phenomenon and activates other cardioprotective pathways as well, it is not surprising that both experimental and clinical studies show striking myocardial salvage with intravenous infusions of adenosine administered in the peri-reperfusion period. For example, a post hoc analysis of the AMISTAD II trial indicates a significant reduction in 1 and 6-month mortality in STEMI patients undergoing reperfusion therapy who are treated with adenosine within 3 hours of symptoms. In conclusion, adenosine's numerous cardioprotective effects, including attenuation of the "no-reflow" phenomenon, support its use in high risk STEMI undergoing reperfusion.

Full Text Available Background and Aims: Magnesium, a physiological antagonist of calcium and N-methyl-d-aspartate, has a role in the prevention of pain in patients undergoing surgery for peripheral vascular diseases with cardiac comorbidities such as ischaemic heart disease and coronary artery disease. The objective of our study was assessment of effects of epidural magnesium in cardiac patients undergoing vascular surgery. Methods: Sixty patients of either sex American Society of Anesthesiologists physical status III undergoing surgeries for peripheral vascular diseases were enrolled. The control group had 30 patients who received levobupivacaine 0.25% 10 ml with fentanyl 50 μg while 30 patients in study group received levobupivacaine 0.25% 10 ml with fentanyl 50 μg and magnesium 100 mg. The primary outcome was duration of analgesia. Sedation score, pain assessment using visual analogue scale (VAS, systolic blood pressure (SBP and diastolic blood pressure (DBP, heart rate (HR, respiratory rate (RR and fentanyl consumption were also recorded. Statistical analyses were performed using Minitab 15 statistical software. Results: Both groups were similar demographically and with respect to baseline HR, SBP, DBP and RR. In the study group, compared to the control group, duration of analgesia was 4.17 ± 1.07 h versus 1.55 ± 0.47 h (P < 0.01, sedation score were\\ better (P = 0.003 and the VAS scores was lower (P < 0.01. sConclusion: Epidural magnesium, added to levobupivacaine and fentanyl as a single bolus dose effectively prolongs the duration of analgesia in high-risk cardiac patients undergoing peripheral vascular surgery.

"ROLE OF ALLOGENEIC TRANSPLANTATION IN MULTIPLE MYELOMA IN THE ERA OF NEW DRUGS"

Directory of Open Access Journals (Sweden)

Benedetto Bruno

2010-06-01

            Allografting is a potentially curative treatment for a subset of multiple myeloma patients for its well documented graft-vs-myeloma effects. However, its role has been hotly debated. Even though molecular remissions have been reported up to 50% after high-dose myeloablative conditionings, their applications, given the high toxicity, have been for long limited to younger relapsed/refractory patients. These limitations have greatly been reduced through the introduction of non-myeloablative/reduced-intensity conditionings.             The introduction of new drugs, characterised by low risks of early mortality, indeed requires to define role and timing of an allograft to capture the subset of patients who may most benefit from graft-vs-myeloma effects.   Ultimately, new drugs should not be viewed as mutually exclusive with an allograft. They may be employed to achieve profound cytoreduction before and enhance graft-versus-myeloma effects as consolidation/maintenance therapy after an allograft. However, this combination should be explored only in well-designed clinical trials.

Cryotherapy effect on oral mucositis severity among recipients of bone marrow transplantation: a literature review.

Science.gov (United States)

Tayyem, Abdel-Qader Mahmoud

2014-08-01

Oral mucositis is a distressing toxic effect of cancer therapy and one of the major side effects of the myeloablative conditioning used to prepare patients for bone marrow transplantation (BMT). Oral cryotherapy is one of the recent modalities used to prevent and manage oral mucositis. The purpose of this review is to clarify the cryotherapy effect on oral mucositis severity among patients receiving myeloablative conditioning followed by BMT. A literature search was performed using six different electronic databases: CINAHL®, MEDLINE®, Nursing Ovid, PubMed, Springer, and Science Direct. Six articles were deemed relevant and included in this review. Oral mucositis increases mortality rate, length of hospital stay, opioid use, and the need for parenteral nutrition usage. It also decreases patient's quality of life and his or her desire to complete treatment. However, oral cryotherapy significantly minimizes the incidence and severity of oral mucositis and decreases secondary oral mucositis complications. Using oral cryotherapy concurrently with a regular oral care protocol can improve its efficacy for preventing and managing oral mucositis. Additional studies should be conducted to create standard oral cryotherapy protocols.

Adolescents and young adults (AYAs) with cancer are a unique group of patients in terms of disease incidence and biology, outcome, and psychosocial needs. This study aims to correlate the risk of graft-versus-host disease (GvHD) and age in a population of children and young adults with acute leukemia undergoing hematopoietic stem cell transplantation (HSCT) in first complete remission (CR). We analyzed the outcome of 153 consecutive children (<15 years), AYAs (15-24 years), and adults (25-35 years) with lymphoblastic or myeloid acute leukemia in first CR who underwent HSCT with matched donors after myeloablative conditioning. GvHD prophylaxis was methotrexate and cyclosporine A (CsA) in all patients. The cumulative incidence of grade II-IV acute GvHD (aGvHD) was significantly higher in AYA patients than in children (subdistribution hazard ratio (SHR), 2.04, p = 0.005) or adults (SHR 1.59, p = 0.048). Both gut and skin aGvHD occurred more frequently in AYA patients. Increasing CsA blood levels with age could not fully account for this difference. No difference in terms of grade III-IV aGvHD was observed. Chronic GvHD was more frequent in AYAs (SHR 2.81, p = 0.007) and adults (SHR 2.31, p = 0.033) than in children. No difference in terms of nonrelated mortality and overall survival was observed among the age subgroups. Since GvHD occurrence is strongly correlated to quality of life, specific attention should be paid to AYAs undergoing HSCT. Further studies should investigate the reasons for the excess of GvHD observed in this population.

Full Text Available Selecting an ideal antithrombotic therapy for elderly patients with atrial fibrillation (AF undergoing percutaneous coronary intervention (PCI can be challenging since they have a higher thromboembolic and bleeding risk than younger patients. The current study aimed to assess the efficacy and safety of triple therapy (TT: oral anticoagulation plus dual antiplatelet therapy: aspirin plus clopidogrel in patients ≥75 years of age with atrial fibrillation (AF undergoing percutaneous coronary intervention (PCI.A prospective multicenter study was conducted from 2003 to 2012 at 6 Spanish teaching hospitals. A cohort study of consecutive patients with AF undergoing PCI and treated with TT or dual antiplatelet therapy (DAPT was analyzed. All outcomes were evaluated at 1-year of follow-up.Five hundred and eighty-five patients, 289 (49% of whom were ≥75 years of age (79.6±3.4 years; 33% women were identified. TT was prescribed in 55.9% of patients at discharge who had a higher thromboembolic risk (CHA2DS2VASc score: 4.23±1.51 vs 3.76±1.40, p = 0.007 and a higher bleeding risk (HAS-BLED ≥3: 88.6% vs 79.2%, p = 0.02 than those on DAPT. Therefore, patients on TT had a lower rate of thromboembolism than those on DAPT (0.6% vs 6.9%, p = 0.004; HR 0.08, 95% CI: 0.01-0.70, p = 0.004. Major bleeding events occurred more frequently in patients on TT than in those on DAPT (11.7% vs 2.4%, p = 0.002; HR 5.2, 95% CI: 1.53-17.57, p = 0.008. The overall mortality rate was similar in both treatment groups (11.9% vs 13.9%, p = 0.38; however, after adjustment for confounding variables, TT was associated with a reduced mortality rate (HR 0.33, 95% CI: 0.12-0.86, p = 0.02.In elderly patients with AF undergoing PCI, the use of TT compared to DAPT was associated with reduced thromboembolism and mortality rates, although a higher rate of major bleeding.

Increased cell surface metallopeptidase activity in cells undergoing UV-induced apoptosis

Full text: We have previously shown that UVC irradiation activated a range of cell surface peptidases (CSP) in HeLa cell monolayer cultures 20 h post-irradiation (1). In cells undergoing apoptosis there is an increase in CSP activity compared to control viable cells in cultures which have been treated by a wide range of agents including UV-irradiation (2). In order to further understand the mechanism involved in this process, we induced apoptosis in HeLa cells using 500 Jm -2 UVB. The separation of viable, apoptotic and necrotic cells of irradiated HeLa cell cultures was made by FACS analysis and sorting. The three populations were distinguished by their staining with PI and Hoechst 33342 dyes. CSP activity was measured using the P9 assay developed in this laboratory (1-3). The viable fraction of the irradiated cells had a higher level of CSP activity compared to unirradiated controls. The level of CSP activity in the apoptotic fraction was higher than that of the viable fraction, however that of the necrotic fraction was significantly lower. This finding agreed with that seen in UVC-irradiated (50 Jm -2 ) cultures (2). In order to elucidate the mechanism by which CSP activity was increased in UVB-irradiated cells undergoing apoptosis, the cultures were treated with the following agents: bestatin, aminopeptidase inhibitor, DEVD, caspase 3 inhibitor, and 3-aminobenzamide (3AB), PARP activation inhibitor. Bestatin and DEVD did not affect the level of CSP activity in the different cell subpopulations following UVB-irradiation. Treatment with 3AB abolished the increased CSP activity seen in the viable and apoptotic fraction following UVB-irradiation. All treated cells had the same morphology as observed under EM. The degree of phosphatidylserine eversion on the cell membrane was similar as were the cleavage profiles of PARP and actin. Only DEVD-treated cells had reduced caspase 3 activity which confirmed that the activation of CSP activity in apoptotic cells is

Full Text Available The usefulness of dental approaches, such as oral management, has gained recognition among patients treated for head and neck cancer. In particular, oral management plays a very important role before, during, and after treatment in patients undergoing radiotherapy, chemotherapy, or a combination of both. However, specialized dentistry knowledge and techniques that are useful for patients undergoing radiotherapy for head and neck cancer have yet to be reported. Therefore, in this review article, our aim is to introduce dental approaches in radiotherapy for patients with head and neck cancer that have been developed and are currently being used at our institute.

There are an increasing number of patients of working age undergoing hip and knee replacements. Currently there is variation in the advice and support given about sickness absence, recovery to usual activities and return to work after these procedures. Earlier, sustainable, return to work improves the health of patients and benefits their employers and society. An intervention that encourages and supports early recovery to usual activities, including work, has the potential to reduce the health and socioeconomic burden of hip and knee replacements. A two-phase research programme delivered over 27 months will be used to develop and subsequently test the feasibility of an occupational advice intervention to facilitate return to work and usual activities in patients undergoing lower limb arthroplasty. The 2 phases will incorporate a six-stage intervention mapping process: Phase 1: Intervention mapping stages 1-3: 1 Needs assessment (including rapid evidence synthesis, prospective cohort analysis and structured stakeholder interviews) 2 Identification of intended outcomes and performance objectives 3 Selection of theory-based methods and practical strategies Phase 2: Intervention mapping stages 4-6: 4 Development of components and materials for the occupational advice intervention using a modified Delphi process 5 Adoption and implementation of the intervention 6 Evaluation and feasibility testing The study will be undertaken in four National Health Service (NHS) hospitals in the United Kingdom and two Higher Education Institutions. OPAL (Occupational advice for Patients undergoing Arthroplasty of the Lower limb) aims to develop an occupational advice intervention to support early recovery to usual activities including work, which is tailored to the requirements of patients undergoing hip and knee replacements. The developed intervention will then be assessed with a specific focus on evaluating its feasibility as a potential trial intervention to improve speed of

This retrospective cohort study evaluated the obstetric outcomes in women with polycystic ovary syndrome (PCOS) and isolated polycystic ovaries (PCO) undergoing in vitro fertilization (IVF) treatment. We studied 104 women with PCOS, 184 with PCO and 576 age-matched controls undergoing the first IVF treatment cycle between 2002 and 2009. Obstetric outcomes and complications including gestational diabetes (GDM), gestational hypertension (GHT), gestational proteinuric hypertension (PET), intrauterine growth restriction (IUGR), gestation at delivery, baby's Apgar scores and admission to the neonatal intensive care unit (NICU) were reviewed. Among the 864 patients undergoing IVF treatment, there were 253 live births in total (25 live births in the PCOS group, 54 in the PCO group and 174 in the control group). The prevalence of obstetric complications (GDM, GHT, PET and IUGR) and the obstetric outcomes (gestation at delivery, birth weight, Apgar scores and NICU admissions) were comparable among the three groups. Adjustments for age and multiple pregnancies were made using multiple logistic regression and we found no statistically significant difference among the three groups. Patients with PCO ± PCOS do not have more adverse obstetric outcomes when compared with non-PCO patients undergoing IVF treatment.

OBJECTIVE To determine factors affecting race speed in Swedish Standardbred horses undergoing surgery of the carpal flexor sheath (CFS), to investigate whether preoperative racing speed was associated with specific intraoperative findings and whether horses returned to racing, and to compare the performance of horses undergoing surgery of the CFS with that of age- and sex-matched control horses. ANIMALS 149 Swedish Standardbred trotters undergoing surgery of the CFS and 274 age- and sex-matched control horses. PROCEDURES Medical records of CFS horses were examined. Racing data for CFS and control horses were retrieved from official online records. Generalizing estimating equations were used to examine overall and presurgery racing speeds and the association of preoperative clinical and intraoperative findings with preoperative and postoperative speeds. Multivariable regression analysis was used to examine career earnings and number of career races. Kaplan-Meier survival analysis was used to compare career longevity between CFS and control horses. RESULTS CFS horses were significantly faster than control horses. The CFS horses that raced before surgery were slower as they approached the surgery date, but race speed increased after surgery. There were 124 of 137 (90.5%) CFS horses that raced after surgery. No intrathecal pathological findings were significantly associated with preoperative racing speed. Career longevity did not differ between CFS and control horses. CONCLUSIONS AND CLINICAL RELEVANCE Horses undergoing surgery of the CFS had a good prognosis to return to racing after surgery. Racing careers of horses undergoing surgery of the CFS were not significantly different from racing careers of control horses.

Full Text Available Whether low-concentration desflurane reinforces propofol-based intravenous anesthesia on maintenance of anesthesia for patients undergoing laparoscopic cholecystectomy is to be determined. The aim of this study was to investigate whether propofol-based anesthesia adding low-concentration desflurane is feasible for laparoscopic cholecystectomy. Fifty-two patients undergoing laparoscopic cholecystectomy were enrolled in the prospective, randomized, clinical trial. Induction of anesthesia was achieved in all patients with fentanyl 2 μg/kg, lidocaine 1 mg/kg, propofol 2 mg/kg, and rocuronium 0.8 mg/kg to facilitate tracheal intubation and to initiate propofol target-controlled infusion (TCI to effect site concentration (Ce: 4 μg/mL with infusion rate 400 mL/h. The patients were then allocated into either propofol TCI based (group P or propofol TCI adding low-concentration desflurane (group PD for maintenance of anesthesia. The peri-anesthesia hemodynamic responses to stimuli were measured. The perioperative psychomotor test included p-deletion test, minus calculation, orientation, and alert/sedation scales. Group PD showed stable hemodynamic responses at CO2 inflation, initial 15 minutes of operation, and recovery from general anesthesia as compared with group P. There is no significant difference between the groups in operation time and anesthesia time, perioperative psychomotor functional tests, postoperative vomiting, and pain score. Based on our findings, the anesthetic technique combination propofol and desflurane for the maintenance of general anesthesia for laparoscopic cholecystectomy provided more stable hemodynamic responses than propofol alone. The combined regimen is recommended for patients undergoing laparoscopic cholecystectomy.

Current standard antithrombotic therapy after coronary stent implantation consists of lifelong aspirin and clopidogrel for a variable period depending in part on the stent type. Despite its well-established efficacy in reducing cardiac-related death, myocardial infarction, and stroke, dual antiplatelet therapy with aspirin and clopidogrel is not without shortcomings. While clopidogrel may be of little beneficial effect if administered immediately prior to PCI and may even increase major bleeding risk if coronary artery bypass grafting is anticipated, early discontinuation of the drug may result in insufficient antiplatelet coverage with thrombotic complications. Optimal and rapid inhibition of platelet activity to suppress ischemic and thrombotic events while minimizing bleeding complications is an important therapeutic goal in the management of patients undergoing percutaneous coronary intervention. In this article we present an overview of the literature on clinical trials evaluating the different aspects of antithrombotic therapy in patients

The Patient-Reported Outcomes Measurement Information System (PROMIS) was developed as an extensive question bank with multiple health domains that could be utilized for computerized adaptive testing (CAT). In the present study, we investigated the use of the PROMIS Physical Function CAT (PROMIS PF CAT) in an otherwise healthy population scheduled to undergo surgery for meniscal injury with the hypotheses that (1) the PROMIS PF CAT would correlate strongly with patient-reported outcome instruments that measure physical function and would not correlate strongly with those that measure other health domains, (2) there would be no ceiling effects, and (3) the test burden would be significantly less than that of the traditional measures. Patients scheduled to undergo meniscal surgery completed the PROMIS PF CAT, Knee injury and Osteoarthritis Outcome Score (KOOS), Marx Knee Activity Rating Scale, Short Form-36 (SF-36), and EuroQol-5 Dimension (EQ-5D) questionnaires. Correlations were defined as high (≥0.7), high-moderate (0.61 to 0.69), moderate (0.4 to 0.6), moderate-weak (0.31 to 0.39), or weak (≤0.3). If ≥15% respondents to a patient-reported outcome measure obtained the highest or lowest possible score, the instrument was determined to have a significant ceiling or floor effect. A total of 107 participants were analyzed. The PROMIS PF CAT had a high correlation with the SF-36 Physical Functioning (PF) (r = 0.82, p ceiling effects, with 0% of the participants achieving the lowest and highest score, respectively. The PROMIS PF CAT correlates strongly with currently used patient-reported outcome measures of physical function and demonstrates no ceiling effects for patients with meniscal injury requiring surgery. It may be a reasonable alternative to more burdensome patient-reported outcome measures.

The aim of this study was to characterize the pharmacokinetics (PK) of propofol in ICU patients undergoing long-term sedation and to assess the influence of routinely collected covariates on the PK parameters. Propofol concentration-time profiles were collected from 29 patients. Non-linear mixed-effects modelling in NONMEM 7.2 was used to analyse the observed data. The propofol pharmacokinetics was best described with a three-compartment disposition model. Non-parametric bootstrap and a visual predictive check were used to evaluate the adequacy of the developed model to describe the observations. The typical value of the propofol clearance (1.46 l/min) approximated the hepatic blood flow. The volume of distribution at steady state was high and was equal to 955.1 l, which is consistent with other studies involving propofol in ICU patients. There was no statistically significant covariate relationship between PK parameters and opioid type, SOFA score on the day of admission, APACHE II, predicted death rate, reason for ICU admission (sepsis, trauma or surgery), gender, body weight, age, infusion duration and C-reactive protein concentration. The population PK model was developed successfully to describe the time-course of propofol concentration in ICU patients undergoing prolonged sedation. Despite a very heterogeneous group of patients, consistent PK profiles were observed. Copyright © 2016 John Wiley & Sons, Ltd. Copyright © 2016 John Wiley & Sons, Ltd.

Approximately 300 children ages 0 to 18 are diagnosed with cancer in Sweden every year, and 80 to 90 of them undergo radiotherapy treatment. The aim was to describe children's experiences of preparing for and undergoing radiotherapy, and furthermore to describe children's suggestions for improvement. Thirteen children between the ages of 5 and 15 with various cancer diagnoses were interviewed. Data was analyzed using qualitative content analysis. The findings revealed five categories: positive and negative experiences with hospital stays and practical arrangements; age-appropriate information, communication, and guidance to various degrees; struggle with emotions; use of distraction and other suitable coping strategies; and children's suggestions for improvement during radiotherapy. An overarching theme emerged: "It is tough and tiring but it works". Some key areas were: explanatory visits, the need for information and communication, being afraid, discomfort and suffering, the need for media distraction, dealing with emotions, and the need for support. A systematic, family-centered preparation program could possible help families prepare and individualized distraction during radiotherapy could contribute to reducing distress. Further studies with interventions could clarify successful programs.

Disseminated intravascular coagulation (DIC) is a severe life-threatening acute bleeding disorder. Traumatized tissues, tumors, necrotic tissues, or bacterial endotoxines release similar material in the blood to the tissutal factors activating the coagulation cascade. This preliminary study was aimed at verifying the risk of DIV in patients undergoing US-guided transperineal prostatic biopsy with Chiba and Tru-Cut needles. To evaluate the activation degree of coagulation factors in the circulation, the authors measured the concentrations of urinary fibrin degradation products in 10 patients undergoing US-guided transperineal prostatic biopsy, both before and after biopsy, every second hour, for 24 hours. Every tube of urine sample contained soya bean trypsin inhibitor and bovine thrombin to prevent any further fibrin degradation during incubation period for the possible presence of blood in urine samples. The results showed that 7/10 patients had marked increase in urinary fibrin degradation product levels (up to 800 XXXX%), with a 3-phase trend: early peak after 2-6 hours, middle peak after 6-14 hours, and late peak after 18-24 hours, which proved the activation of the coagulation cascade

The aim of this study was to explore whether postmenopausal breast cancer survivors undergoing aromatase inhibitor therapy differ from healthy postmenopausal women in their response to the same aerobic + resistance training. The participants were separated into two groups: postmenopausal breast cancer survivors undergoing aromatase inhibitor therapy for an average of 20 months (18 women) and healthy postmenopausal women (24 women). We assessed aerobic capacity (predicted maximum oxygen uptake (VO 2 max) and maximum running velocity test (Vmax)) through a walking test, upper and lower body muscle strength using an estimated one-repetition maximum test, and body composition by dual-energy X-ray absorptiometry at baseline and at three, six, and nine months, respectively. The exercise program was performed three times/week over nine months and consisted of 40 min of machine-based strength training (seated cable row, bench press, leg extension, leg press, and leg curl, as well as bridge, abdominal, and standard plank exercises) followed by 30 min of treadmill walking. Analysis of variance (ANOVA) with repeated measures was used to compare the groups over time. Postmenopausal breast cancer survivors undergoing aromatase inhibitor therapy and healthy postmenopausal women presented similar improvements in estimated lower body strength, predicted VO 2max and V max , and body fat mass. For maximal upper body strength, there was a significant group x time interaction after six months of training (p = 0.01). The healthy postmenopausal women presented a significant increase in upper body strength after six months, while postmenopausal breast cancer survivors undergoing aromatase inhibitor therapy demonstrated an improvement only at nine months of training. The breast cancer survivors undergoing aromatase inhibitor therapy presented increased lean mass while healthy postmenopausal women maintained values over time (Breast cancer: 33.7 ± 3.9(Pre) vs. 34.1�

The purpose of this study was to determine differences in age, gender, and the need for bilateral surgery between high-level athletes grouped by sports with similar mechanical demands on the hip and recreational athletes undergoing hip arthroscopy for femoroacetabular impingement (FAI). By use of a hip-preservation center registry, a retrospective review of patients undergoing hip arthroscopy for FAI between March 2010 and April 2012 was performed. Athletes were categorized as high level (high school, collegiate, or professional) or recreational. We performed a subgroup analysis for high-level athletes, looking at differences among contact, cutting, impingement, overhead/asymmetric, endurance, and flexibility sports. The study included 288 high-level athletes and 334 recreational athletes. Being a high-level athlete was associated with a younger age (mean age, 20.2 years v 33.0 years; odds ratio, 0.69; P gender (61.5% v 53.6%; odds ratio, 1.75; P = .03). The percentage of high-level athletes undergoing bilateral surgery was higher than that of recreational athletes (28.4% v 15.9%); however, this association was found to be confounded by age on multivariate analysis. The most common sports for high-level athletes were soccer, hockey, and football. Athletes participating in cutting sports were significantly younger than athletes participating flexibility, contact, or impingement sports. When compared with recreational athletes undergoing arthroscopic treatment for FAI, high-level athletes are more likely to be younger, to be male, and to undergo bilateral surgery. When high-level athletes are grouped by the mechanical demands placed on the hip by their sport, athletes participating in cutting sports are more likely to be younger than those in the other groups.

Studies into Ge-Te, In-Te, Al-Mn, Sb-Zn, Sn-Au systems are carried out at melt cooling rates from 50 deg/h to 10 5 deg/h to establish regularities in stable and metastable crystallization of alloys undergoing peritectic transformations. Methods of metallographic, X-ray phase and X-ray diffraction analyses are used. Differentiation in types of peritectic transformations is made through their mechanisms under equilibrium and non-equilibrium crystallization conditions for various alloy systems. It is found out that ability to supercooling even at low or moderate cooling rates for Te-Ge and Te-In system melts can be one of the main indication of the possibility of amorphous alloy formation [ru

Abstract Aims The aim of this study was to investigate the association between hypothyroidism and major adverse cardiovascular and cerebral events (MACCE) in patients undergoing percutaneous coronary intervention (PCI). Methods and results Two thousand four hundred and thirty patients who underwent PCI were included. Subjects were divided into two groups: hypothyroidism ( n = 686) defined either as a history of hypothyroidism or thyroid-stimulating hormone (TSH) ≥5.0 mU/mL, and euthyroidism ( n = 1744) defined as no history of hypothyroidism and/or 0.3 mU/mL ≤ TSH hypothyroidism were further categorized as untreated ( n = 193), or those taking thyroid replacement therapy (TRT) with adequate replacement (0.3 mU/mL ≤ TSH hypothyroidism compared with those with euthyroidism (MACCE: HR: 1.28, P = 0.0001; myocardial infarction (MI): HR: 1.25, P = 0.037; heart failure: HR: 1.46, P = 0.004; revascularization: HR: 1.26, P = 0.0008; stroke: HR: 1.62, P = 0.04). Compared with untreated patients or those with inadequate replacement, adequately treated hypothyroid patients had a lower risk of MACCE (HR: 0.69, P = 0.005; HR: 0.78, P = 0.045), cardiac death (HR: 0.43, P = 0.008), MI (HR: 0.50, P = 0.0004; HR: 0.60, P = 0.02), and heart failure (HR: 0.50, P = 0.02; HR: 0.52, P = 0.017). Conclusion Hypothyroidism is associated with a higher incidence of MACCE compared with euthyroidism in patients undergoing PCI. Maintaining adequate control on TRT is beneficial in preventing MACCE.

We investigated whether patients undergoing vaginal delivery who developed peripartum fever (PPF) had increased rates of other gestational complications. A retrospective study was undertaken comparing pregnancy complications of patients who developed PPF with those who did not. A multivariable logistic regression model was constructed to control for confounders. To avoid ascertainment bias, the year of birth was included in the model. Women who underwent cesarean delivery and those with multiple pregnancies were excluded from the study. During the study period, there were 169,738 singleton vaginal deliveries, and 0.4% of the women suffered from PPF. Hypertensive disorders, induction of labor, dystocia of labor in the second stage, suspected fetal distress, meconium-stained amniotic fluid, postpartum hemorrhage, manual lysis of a retained placenta, and revision of the uterine cavity and cervix were found to be independently associated with PPF by multivariable analysis. Year of birth was found to be a risk factor for fever. Apgar scores lower than 7 at 1 but not 5 minutes were significantly higher in the PPF group. Perinatal mortality rates were significantly higher among women with PPF (6.7% versus 1.3%, odds ratio [OR] = 5.4; 95% confidence interval [CI] 3.9 to 7.3; P < 0.001). Using another multivariable analysis, with perinatal mortality as the outcome variable, PPF was found as an independent risk factor for perinatal mortality (OR = 2.9; 95% CI 1.9 to 4.6; P < 0.001). PPF in women undergoing vaginal deliveries is associated with adverse perinatal outcomes and specifically is an independent risk factor for perinatal mortality.

The aim of the present study was to investigate changes in emotional state and the relationship between emotional state and demographic/clinical factors and coping style among gynecologic patients undergoing surgery. Using the Japanese version of the Profile of Mood States (POMS), 90 patients (benign disease: 32, malignancy: 58) were examined on three occasions: before surgery, before discharge, and 3 months after discharge. They were also examined using the Coping Inventory for Stressful Situations (CISS) on one occasion before discharge. The scores for the subscales depression, anger, and confusion were the highest after discharge while those for anxiety were the highest before surgery. The average scores of the POMS subscales for all subjects were within the normal range. With regard to the relationship between these emotional states and other factors, multiple regressions showed that the principal determinants of anxiety before surgery were religious belief, psychological symptoms during hospitalization and emotion-oriented (E) coping style; further, it was found that depression after discharge could be explained by chemotherapy, duration of hospitalization, and E coping style. The principal determinants of anger after discharge and vigor before surgery were length of education and E coping style, and severity of disease, chemotherapy, E coping style and task-oriented coping style, respectively. Those of post-discharge fatigue and confusion were length of education, psychological symptoms, and E coping style. In summary it is suggested that the following should be taken into account in patients undergoing gynecologic surgery: anxiety before surgery, depression, anger, and confusion after surgery, including coping styles.

To compare the clinical outcomes and cost-effectiveness of luteal phase down-regulation with gonadotrophin-releasing hormone (GnRH) agonist protocol and GnRH antagonist protocol in patients undergoing repeated in vitro fertilization and intracytoplasmic sperm injection (IVF-ICSI) cycles. A retrospective analysis of clinical outcomes and costs was conducted among 198 patients undergoing repeated IVF-ICSI cycles, including 109 receiving luteal phase down-regulation with GnRH agonist protocol (group A) and 89 receiving GnRH antagonist protocol (group B). The numbers of oocytes retrieved and good embryos, clinical pregnancy rate, abortion rate, the live birth rate, mean total cost, and the cost-effective ratio were compared between the two groups. In patients undergoing repeated IVF-ICSI cycles, the two protocols produced no significant differences in the number of good embryos, clinical pregnancy rate, abortion rate, or twin pregnancy rate. Compared with group B, group A had better clinical outcomes though this difference was not statistically significant. The number of retrieved oocytes was significantly greater and live birth rate significantly higher in group A than in group B (9.13=4.98 vs 7.11=4.74, and 20.2% vs 9.0%, respectively). Compared with group B, group A had higher mean total cost per cycle but lower costs for each oocyte retrieved (2729.11 vs 3038.60 RMB yuan), each good embryo (8867.19 vs 9644.85 RMB yuan), each clinical pregnancy (77598.06 vs 96139.85 RMB yuan). For patients undergoing repeated IVF/ICSI cycle, luteal phase down-regulation with GnRH agonist protocol produces good clinical outcomes with also good cost-effectiveness in spite an unsatisfactory ovarian reserve.

In this study, we identified the factors influencing behavioral intention to undergo Papanicolaou testing among Japanese and Korean women in early adulthood. Their behavioral intentions were compared in this cross-sectional descriptive study. In total, 887 women (Japanese = 498, Korean = 389) aged 20-39 years participated in this study. Using a self-report questionnaire, knowledge, attitudes, subjective norm, perceived behavioral control, and behavioral intention were surveyed. There were significant differences between Japanese and Korean women's scores on all main variables. For Japanese women, all the variables moderately correlated with behavioral intention. In comparison, for Korean women, all independent variables, except for knowledge, moderately correlated with behavioral intention. Through a multiple regression analysis, age, undergoing Papanicolaou testing, attitudes, subjective norm, and perceived behavioral control were identified as significant predictors of behavioral intention among Japanese women. Among Korean women, job status, undergoing a Papanicolaou test, attitudes, subjective norm, and perceived behavioral control were demonstrated as significant predictors of behavioral intention. Health professionals should consider these factors to encourage Papanicolaou testing in women in early adulthood. © 2017 John Wiley & Sons Australia, Ltd.

To evaluate the effect of Supportan, an enteral nutrition (EN) specific for tumor patients, on the nutritional status and immune function of late-staged gastric cancer patients undergoing chemotherapy. Sixty-six late-staged gastric cancer patients undergoing chemotherapy were randomly divided into EN group (n=33) and control group (n=33). During chemotherapy, the patients in EN group received Supportan and the patients in the control group received basic diet. On the 14th day before chemotherapy and after chemotherapy, nutritional status and cell immune indicators were evaluated. As for nutrition indicators, there were no significant differences in EN group before and after chemotherapy (P > 0.05). Total protein, hemoglobin, prealbumin and transferrin significantly decreased after chemotherapy compared with those before chemotherapy in the control group (Pnutrition in EN group were superior to that in the control group, however, the differences were not statistically significant. The incidences of nausea, vomiting and marrow inhibition in Supportan group was lower compared with those in the control group, but with no significant difference. Supportan can prevent malnutrition of the late-staged gastric cancer patients undergoing chemotherapy, and improve immune function and alleviate adverse effects of chemotherapy.

To assess the prevalence of the oral lesions related to HIV-infection (HIV-OL) in HIV+/AIDS adolescents (=13 years old), and the differences with HIV+/AIDS children (=3 - 0.05). Oral candidiasis was the most prevalent oral lesion in both groups. Association (p<0.05) of a high prevalence of HIV-OL and oral candidiasis with a high viral load was observed in both study groups. Adolescents perinatally HIV-infected have a high prevalence of HIV-OL. Oral Candidiasis still is the most frequent oral opportunistic infection. Oral lesions could have association to viral failure in HIV+/AIDS adolescents undergoing HAART.

There is increasing interest in evaluating the use of nonpharmacologic interventions such as music to minimize potential adverse effects of anxiety-reducing medications. This study used a quasi-experimental design to evaluate the effects of a perioperative music intervention (provided continuously throughout the preoperative, intraoperative, and postoperative periods) on changes in mean arterial pressure (MAP), heart rate, anxiety, and pain in women with a diagnosis of breast cancer undergoing mastectomy. A total of 30 women were assigned randomly to a control group or to the music intervention group. Findings indicated that women in the intervention group had a greater decrease in MAP and anxiety with less pain from the preoperative period to the time of discharge from the recovery room compared with women in the control group. Music is a noninvasive and low-cost intervention that can be easily implemented in the perioperative setting, and these findings suggest that perioperative music can reduce MAP, anxiety, and pain among women undergoing mastectomy for breast cancer.

Label-retaining cells (LRCs) have been proposed to represent adult tissue stem cells. LRCs are hypothesized to result from either slow cycling or asymmetric cell division (ACD). However, the stem cell nature and whether LRC undergo ACD remain controversial. Here, we demonstrate label-retaining cancer cells (LRCCs) in several gastrointestinal (GI) cancers including fresh surgical specimens. Using a novel method for isolation of live LRCC, we demonstrate that a subpopulation of LRCC is actively dividing and exhibits stem cells and pluripotency gene expression profiles. Using real-time confocal microscopic cinematography, we show live LRCC undergoing asymmetric nonrandom chromosomal cosegregation LRC division. Importantly, LRCCs have greater tumor-initiating capacity than non-LRCCs. Based on our data and that cancers develop in tissues that harbor normal-LRC, we propose that LRCC might represent a novel population of GI stem-like cancer cells. LRCC may provide novel mechanistic insights into the biology of cancer and regenerative medicine and present novel targets for cancer treatment. PMID:22331764

to evaluate the epidemiological variables and diagnostic and therapeutic modalities related to hepatic trauma patients undergoing laparotomy in a public referral hospital in the metropolitan region of Vitória-ES. we conducted a retrospective study, reviewing charts of trauma patients with liver injuries, whether isolated or in association with other organs, who underwent exploratory laparotomy, from January 2011 to December 2013. We studied 392 patients, 107 of these with liver injury. The male: female ratio was 6.6 : 1 and the mean age was 30.12 years. Penetrating liver trauma occurred in 78.5% of patients, mostly with firearms. Associated injuries occurred in 86% of cases and intra-abdominal injuries were more common in penetrating trauma (p trauma was 60%, and penetrating trauma, 87.5% (p trauma remain high, especially in patients suffering from blunt trauma in relation to penetrating one.

Provision of preoperative information can alleviate patients' anxiety. However, the ideal method of delivering this information is unknown. Video information has been shown to reduce patients' anxiety, although little is known regarding the effect of preoperative multimedia information on anxiety in patients undergoing regional anaesthesia. We randomized 110 patients undergoing upper or lower limb surgery under regional anaesthesia into the study and control groups. The study group watched a short film (created by the authors) depicting the patient's in-hospital journey including either a spinal anaesthetic or a brachial plexus block. Patients' anxiety was assessed before and after the film and 1 h before and within 8 h after their operation, using the Spielberger state trait anxiety inventory and a visual analogue scale. There was no difference in state and trait anxiety between the two groups at enrollment. Women had higher baseline state and trait anxiety than men (P=0.02). Patients in the control group experienced an increase in state anxiety immediately before surgery (P<0.001), and patients in the film group were less anxious before operation than those in the control group (P=0.04). After operation, there was a decrease in state anxiety from baseline in both groups, but patients in the film group were less anxious than the control group (P=0.005). Preoperative multimedia information reduces the anxiety of patients undergoing surgery under regional anaesthesia. This type of information is easily delivered and can benefit many patients.

Current guidelines on venous thromboembolism (VTE) prevention do not reflect the potential varying risk for patients undergoing different urological procedures. Our study aimed to establish the procedure specific rate of postoperative VTE in patients undergoing urological surgery. Hospital Episode Statistics were obtained for all patients undergoing common urological procedures between April 2009 and April 2010. This cohort was followed up to identify all patients reattending with either deep vein thrombosis (DVT) or pulmonary embolism (PE) within 12 months. A total of 126,891 individuals underwent urological surgery during the study period. This included 89,628 men (70.6%) and 37,236 women (29.3%) with a mean age of 65.2 years. At the 12-month follow-up, 839 patients (0.66%) were readmitted with VTE. Of these, 373 (0.29%) were admitted with DVT and 466 (0.37%) with PE. The procedure-specific rate of VTE varied significantly between 2.86% following cystectomy and 0.23% following urethral dilatation. Procedures performed in the lithotomy position carried a significantly lower risk of VTE than those performed in the supine position (0.60% vs 1.28%, p <0.0001). Furthermore, of all procedures performed in the lithotomy position, those performed on benign conditions carried a significantly lower risk than those performed on malignant disease (0.52% vs 0.79%, p <0.0001). Procedure specific rates of postoperative VTE vary widely among patients undergoing urological procedures. These findings suggest the potential benefit of prolonging the use of thromboprophylaxis in high-risk patients but also exploring the apparent lack of need for routine thromboprophylaxis in patients undergoing low-risk procedures.

Full Text Available Objective: The objective of the present study is to determine the incidence of delirium and the associated factors in patients undergoing open heart surgery. Methods: This is an Analytic-descriptive study conducted on 404 patients undergoing elective open heart surgery in Fatemeh Zahra Heart Center, Sari, over the period of 6 months from July to December 2011. Sampling was achieved in a nonrandomized targeted manner and delirium was assessed using NeeCham questionnaire. A trained nurse evaluated the patients for delirium and completed the risk factor checklist on days 1 to 5 after surgery. Data analyses were accomplished using survival analysis (Kaplan-Meier and Cox regression on SPSS software version 15. Results: We found that variables, including ventilation time, increased drainage during the first 24 hours, the need for re-operation in the first 24 hours, dysrhythmias, use of inotropic agents, increased use of analgesics, increased arterial carbon dioxide, lack of visitors, and use of physical restrainers were associated with the development of delirium. In addition, we found a delirium incidence of 29%. Conclusion: Diagnosis of cognitive disorders is of utmost value; therefore, further studies are required to clarify the risk factors because controlling them will help prevent delirium.

Severe secondary hyperparathyroidism (SHPT) is a serious problem in patients undergoing hemodialysis. The efficacy and safety of microwave ablation (MWA), a minimally invasive treatment, for severe SHPT are as yet unclear. To clarify the role of MWA, we administered it to patients with severe SHPT and assessed its efficacy and safety. This was a prospective, single-center, single-arm, clinical trial. We enrolled patients with severe SHPT attending our hemodialysis center who met the inclusion and exclusion criteria. We then assessed primary outcome measures (serum concentrations of intact parathyroid hormone) and secondary outcome measures (serum concentrations of calcium and phosphorus). Twenty-six patients were enrolled in this study, 10 of whom (38.46%) were responsive to MWA and 16 (61.54%) of whom were not. The main complication was hypocalcemia (10 cases, 38.46%), which had occurred in all cases by one week after administration of MWA. Responding patients with hypocalcemia all achieved normal serum calcium concentrations within seven months and non-responding patients within three months. There were no changes in serum phosphorus concentrations after MWA in either responders or non-responders. Microwave ablation is relatively ineffective in patients with severe SHPT undergoing maintaining hemodialysis and should not be the initial therapy in such cases.

Full Text Available Background: Coronary artery bypass graft surgery is an important treatment for the patients with coronary artery disease to reduce angina and enhance the quality of life. Anxiety is a usual reaction to a stressful situation and is existing in patients awaiting surgery. Objective: The objective of the study was to assess pre-operative anxiety in patients who were undergoing coronary artery bypass graft surgery. Methods: A cross-sectional study consisting of 140 patients undergoing coronary artery bypass graft surgery were included in the study using a convenience sampling technique in a tertiary care referral hospital. The data was collected using state-trait anxiety inventory. The data were entered into SPSS (version – 20.0 for windows and descriptive and inferential statistics were performed. Results: The study enrolled 140 (117 males and 23 females patients. Their mean age was 57.29 ± 8.14 (range 35–70 years. Most of the patients 118 (84% had preoperative anxiety before coronary artery bypass graft surgery. There was an association found between gender and anxiety with Pearson chi-square value of 11.57 (p < 0.001. Discussion: Patients undergoing coronary artery bypass graft surgery is experiencing the high level of pre-operative anxiety and females had higher anxiety than the males. Identification of the pre-operative anxiety in patients undergoing CABG surgery is essential because it helps the health professionals and nurses to develop effective and appropriate interventions.

To compare the outcome of pars-plana-modified Ahmed glaucoma valve (AGV) versus limbal-based conventional AGV into the anterior chamber, in patients undergoing penetrating keratoplasty (PK) for glaucoma with coexisting corneal diseases. In this prospective randomized clinical trial, 58 eyes of 58 patients with glaucoma and coexisting corneal disease were divided into two groups. Group 1 (29 eyes of 29 patients) included patients undergoing limbal-based conventional AGV into the anterior chamber (AC) along-with PK and group 2 (29 eyes of 29 patients) included those undergoing pars-plana-modified AGV along-with PK. Outcome measures included corneal graft clarity, intraocular pressure (IOP), number of antiglaucoma medications, and postoperative complications. Patients were followed up for a minimum period of 2 years. Out of 58 eyes (58 patients), 50 eyes (50 patients: 25 eyes of 25 patients each in group 1 and group 2) completed the study and were analyzed. Complete success rate for AGV (group 1: 76%; group 2: 72%; p = 0.842) and corneal graft clarity (group 1: 68%; group 2: 76%; p = 0.081) were comparable between the two groups at 2 years. Graft failure was more in conventional AGV (32%) as compared to pars plana-modified AGV (24%) but not statistically significant (p = 0.078) at 2 years. Though both procedures were comparable in various outcome measures, pars-plana-modified AGV is a viable option for patients undergoing PK, as it provides a relatively better corneal graft survival rate and lesser complications that were associated with conventional AGV.

Generally, before being operated on, patients will be given informal information by the healthcare providers involved in the care of the patients (doctors, nurses, ward clerks, or healthcare assistants). This information can also be provided formally in different formats including written information, formal lectures, or audio-visual recorded information. To compare the benefits and harms of formal preoperative patient education for patients undergoing laparoscopic cholecystectomy. We searched the Cochrane Central Register of Controlled Trials (CENTRAL) (Issue 2, 2013), MEDLINE, EMBASE, and Science Citation Index Expanded to March 2013. We included only randomised clinical trials irrespective of language and publication status. Two review authors independently extracted the data. We planned to calculate the risk ratio with 95% confidence intervals (CI) for dichotomous outcomes, and mean difference (MD) or standardised mean difference (SMD) with 95% CI for continuous outcomes based on intention-to-treat analyses when data were available. A total of 431 participants undergoing elective laparoscopic cholecystectomy were randomised to formal patient education (215 participants) versus standard care (216 participants) in four trials. The patient education included verbal education, multimedia DVD programme, computer-based multimedia programme, and Power Point presentation in the four trials. All the trials were of high risk of bias. One trial including 212 patients reported mortality. There was no mortality in either group in this trial. None of the trials reported surgery-related morbidity, quality of life, proportion of patients discharged as day-procedure laparoscopic cholecystectomy, the length of hospital stay, return to work, or the number of unplanned visits to the doctor. There were insufficient details to calculate the mean difference and 95% CI for the difference in pain scores at 9 to 24 hours (1 trial; 93 patients); and we did not identify clear evidence of

Quality of life (QOL) of children with cancer reduces right from the diagnosis of disease and the start of treatment. Computer games in medicine are utilized to interact with patients and to improve their health-related behaviors. This study aimed to investigate the effect of an interactive computer game on the QOL of children undergoing chemotherapy. In this clinical trial, 64 children with cancer aged between 8 and12 years were selected through convenience sampling and randomly assigned to experimental or control group. The experimental group played a computer game for 3 hours a week for 4 consecutive weeks and the control group only received routine care. The data collection tool was the Pediatric Quality of Life Inventory (PedsQL) 3.0 Cancer Module Child self-report designed for children aged between 8 to 12 years. Data were analyzed using descriptive and inferential statistics in SPSS software. Before intervention, there was no significant difference between the two groups in terms of mean total QOL score ( p = 0.87). However, immediately after the intervention ( p = 0.02) and 1 month after the intervention ( p computer games seem to be effective as a tool in influencing health-related behavior and improving the QOL of children undergoing chemotherapy. Therefore, according to the findings of this study, computer games can be used to improve the QOL of children undergoing chemotherapy.

Patients undergoing PCI early after fibrinolytic therapy are at high risk for both thrombotic and bleeding complications. We sought to assess the pharmacodynamic effects of ticagrelor versus clopidogrel in the fibrinolytic-treated STEMI patients undergoing early PCI. Patients undergoing PCI within 24 hours of tenecteplase (TNK), aspirin, and clopidogrel for STEMI were randomized to receive additional clopidogrel 300 mg followed by 75 mg daily or ticagrelor 180 mg followed by 90 mg twice daily. The platelet reactivity units (PRU) were measured with the VerifyNow Assay before study drug administration (baseline) at 4 and 24 hours post-PCI. The primary end point was PRU ≤208 at 4 hours. A total of 140 patients (74 in ticagrelor and 66 in clopidogrel group) were enrolled. The mean PRU values at baseline were similar for the 2 groups (257.8±52.9 vs 259.5±56.7, P=.85, respectively). Post-PCI, patients on ticagrelor, compared to those on clopidogrel, had significantly lower PRU at 4 hours (78.7±88 vs 193.6±86.5, respectively, PPCI frequently had PRU >208. In this high-risk population, ticagrelor provides more prompt and potent platelet inhibition compared with clopidogrel (Funded by Astra Zeneca; NCT01930591, https://clinicaltrials.gov/ct2/show/NCT01930591).

To discuss risks and benefits of interhospital transport of children in cardiac arrest undergoing cardiopulmonary resuscitation. Narrative review. Not applicable. Transporting children in cardiac arrest with ongoing cardiopulmonary resuscitation between hospitals is potentially lifesaving if it enables access to resources such as extracorporeal support, but may risk transport personnel safety. Research is needed to optimize outcomes of patients transported with ongoing cardiopulmonary resuscitation and reduce risks to the staff caring for them.

WHO HAS TO UNDERGO CANCER GENETIC TESTING? A PERSPECTIVE.

Directory of Open Access Journals (Sweden)

Carmen Rinaldi

2017-10-01

Full Text Available Genetic testing is a medical tool employed to screen changes in genes linked to cancer and other genetic diseases. Genetic tests are available for breast, ovarian, colon, thyroid, and some other cancers and they represent the main tool for early identification of the “risk” subjects. The choice to undergo genetic testing by a healthy or affected cancer patient with family history of the cancer has to be the fruit of a careful and prudent assessment of the advantages and disadvantages discussed during oncogenetic counselling. The latter, in turn, in the case of a patient's positive and informed choice, must constantly affiliate the genetic testing, in order to preserve the prediction and information role of the test as much as possible.

Full Text Available Introduction. While patients undergoing orthotopic liver transplantation (OLT have high cardiovascular event rates, preoperative risk stratification may not necessarily predict those susceptible patients. Troponin T (TnT may help predict patients at risk for cardiovascular complications. Methods. Consecutive patients undergoing OLT at Mayo Clinic in Florida between 1998 and 2010 who had TnT obtained within 10 days following surgery were included. Three groups were compared based on TnT level: (1 normal (TnT ≤0.01 ng/mL, (2 intermediate (TnT 0.02–0.11 ng/mL, and (3 elevated (TnT >0.11 ng/mL. Overall and cardiovascular mortality was assessed. Results. Of the 78 patients included, there was no difference in age, gender, severity of liver disease, and echocardiographic findings. Patients in the normal and intermediate TnT groups had a lower overall mortality rate (14.3% and 0%, resp. when compared with those with elevated TnT (50%; P=0.001. Patients in the elevated TnT group had a cardiovascular mortality rate of 37.5% compared with 1.4% in the other groups combined (P<0.01. The elevated TnT group had a much higher mortality rate when compared with those in the intermediate group (P<0.0001. Conclusion. TnT may accurately help risk stratify patients in the early postoperative setting to better predict cardiovascular complications.

Objective: To assess the relationship of severity of coronary artery disease with obesity in patients undergoing coronary angiography. Design: Cross sectional study. Place and Duration of Study: Armed Forces Institute of Cardiology - National Institute of Heart Diseases (AFIC-NIHD), 1st February 2010 to 31st August 2010 Patients and Methods: The study population included 468 patients undergoing coronary angiography. Obesity was classified according to the BMI using the National Institutes of Health (NIH) criteria as normal (BMI 21-24 kg/m2), overweight (BMI 25-29 kg/m2), obesity class I (BMI 30-34 kg/m2), obesity class II (BMI 35 to 39 kg/m2 and obesity class III (BMI 40 or above kg/m2). Coronary angiography data were obtained from the Siemens Queries software system, which maintains the database including detailed angiographic findings of all patients at this institution. Significant lesions were defined as those with >70% diameter narrowing of coronary arteries (>50% for the left main coronary artery). We attempted to quantify the 'severity of CAD' by ascertaining the prevalence of High-Risk Coronary Anatomy (HRCA). Results: Insignificant difference was observed in traditional risk factors i.e. age, diabetes mellitus and smoking except hypertension and gender. Statistically significantly low prevalence of HRCA was encountered in the obese group (57.7%) as compared to normal/overweight group (75.8%) (p < 0.05). Conclusion: We conclude that obesity is associated with less severe coronary artery disease. (author)

Full Text Available Introduction: Dysphonia is the main symptom of lesions that affect the vocal tract. Many of those lesions may require surgical treatment. Polyps are one of the most common forms of vocal cord lesions and the most prevalent indication for laryngeal microsurgery. There are different types of polyps, and their different characteristics can indicate different prognosis and treatments. Aim: To conduct a comparative study of polypoid lesions (angiomatous and gelatinous in patients undergoing laryngeal microsurgery via an electronic protocol. Method: We prospectively evaluated 93 patients diagnosed with vocal fold polyps; the polyps were classified as angiomatous or gelatinous. Results: In total, 93 patients undergoing laryngeal microsurgery were diagnosed with vocal fold polyps. Of these, 63 (64.74% had angiomatous and 30 (32.26% gelatinous polyps. Most patients with angiomatous polyps were men; their polyps were frequently of medium size, positioned in the middle third of the vocal fold, and accompanied by minimal structural alterations (MSA. In contrast, the majority of patients with gelatinous polyps were women; their polyps were smaller, positioned in the middle and posterior third of the vocal fold, and were not accompanied by MSA. Both types of polyps were more frequently located on the right vocal fold. Conclusion: Angiomatous polyps were more frequently encountered than gelatinous polyps. In addition, correlations between polyp type and sex, polyp size, position, location, and the presence of MSA were observed. Different surgical techniques were used, but the postoperative results were similar and satisfactory after speech therapy.

Full Text Available Abstract Background Sexual function among women undergoing hemodialysis (HD is under-studied and there is no consensus about the effect of sexual dysfunction (SD on their quality of life (QoL. We aimed to determine the prevalence of SD and to compare QoL between women undergoing maintenance HD with and without SD. Methods We included female end-stage renal disease (ESRD patients undergoing HD during June 2011 in the only renal unit in the north of Ceará state, northeastern Brazil. The criteria for inclusion were age between 18 and 55, at least three months on dialysis and being sexually active. Women using antidepressant medication were excluded. We used the Female Sexual Function Index (FSFI, which evaluates six domains of sexual function, including desire, arousal, lubrication, orgasm, satisfaction and pain. The patients were classified as presenting SD if the total FSFI score was less than 26. For QoL evaluation, we used the validated Brazilian version of SF-36. This is a widely used 36-item questionnaire covering eight dimensions of QoL. Demographic data, time on dialysis, underlying etiology of ESRD, and laboratory measures were assessed in unit records. Results Of a total of 58 women, 46 (79.3% presented SD. There were lower scores related to physical functioning (48.2 vs. 71.2; p = 0.007, bodily pain (45 vs. 67.5; p = 0.010, vitality (52.1 vs. 69.1; p = 0.026 and social functioning (57.2 vs. 76.1; p = 0.034 among women with SD compared to women without SD. Physical functioning and role-physical presented positive linear correlation with FSFI scores, respectively, r = 0.322 (p = 0.013 and r = 0.345 (p = 0.007. Conclusion The prevalence of SD among women on HD is very high, reaching nearly 80%. Women on HD with SD had worse QoL, especially physical aspects of QoL, when compared to women without SD. Therefore, approaches aiming to improve QoL among women undergoing HD should be considered.

Adult patients undergoing nuclear medicine investigations may subsequently come into close contact with members of the public and hospital staff. In order to expand the available dosimetry and derive appropriate recommendations, dose rates were measured at 0.1, 0.5 and 1.0 m from 80 adult patients just before they left the nuclear medicine department after undergoing one of eight 99 Tc m studies, an 123 I thyroid, an 111 In leucocyte or a 201 Tl cardiac scan. The maximum departure dose rates at these distances of 150, 30 and 7.3 μSv h -1 were greater than those found in similar published studies of adult and paediatric patients. To limit the dose to an infant to less than 1 mSv, an 111 In leucocyte scan is the only investigation for which it may be necessary to restrict close contact between the infant and a radioactive parent, depending on the dose rate near the surface of the patient, the parent's habits and how fretful is the infant. It is unlikely that a ward nurse will receive a dose of 60 μSv in a working day if caring for just one radioactive adult patient, unless the patient is classified as totally helpless and had undergone a 99 Tc m marrow, bone or brain scan. The data and revised calculations of effective exposure times based on a total close contact time of 9 h in every 24 h period should allow worst case estimates of radiation dose to be made and recommendations to be formulated for other circumstances, including any future legislative changes in dose limits or derived levels.

Purpose/Objective: The overall quality of patient care is a function of the quality of both its technical and its nontechnical components. The purpose of this study was to identify the elements of nontechnical (personal) care that are most important to patients undergoing radiation therapy for prostate cancer. Methods and Materials: We reviewed the literature and interviewed patients and health professionals to identify elements of personal care pertinent to patients undergoing radiation therapy for prostate cancer. We identified 143 individual elements relating to 10 aspects of personal care. Patients undergoing radical radiation therapy for prostate cancer completed a self-administered questionnaire in which they rated the importance of each element. The overall importance of each element was measured by the percentage of respondents who rated it as “very important.” The importance of each aspect of personal care was measured by the mean importance of its elements. Results: One hundred eight patients completed the questionnaire. The percentage of patients who rated each element “very important” ranged from 7% to 95% (mean 61%). The mean importance rating of the elements of each aspect of care varied significantly: “perceived competence of caregivers,” 80%; “empathy and respectfulness of caregivers,” 67%; “adequacy of information sharing,” 67%; “patient centeredness,” 59%; “accessibility of caregivers,” 57%; “continuity of care,” 51%; “privacy,” 51%; “convenience,” 45%; “comprehensiveness of services,” 44%; and “treatment environment,” 30% (P<.0001). Neither age nor education was associated with importance ratings, but the patient's health status was associated with the rating of some elements of care. Conclusions: Many different elements of personal care are important to patients undergoing radiation therapy for prostate cancer, but the 3 aspects of care that most believe are most important are these: the perceived

Dolan, M.E.

1987-01-01

The gynecology patient undergoing radiation therapy treatments may experience physiological and psychological problems related to sexuality. The needs of this group must be met by the radiation oncology staff by their being informed, interested, and experienced in dealing with sexual problems created by radiation therapy treatments. Opportunities to obtain information and for discussion about how the disease and its treatments will affect sexual functioning must be provided for the patient and partner. It is important to remember that the ability to seek and preserve gratifying sexual function is of great importance to almost all women, regardless of age. The patient may feel much personal distress related to the disease, the treatments, and how they affect the way she feels as a sexual human being. Opportunities must be provided to share the feelings created by the treatment process and trained therapists should be available when intensive sexual counseling is needed

2012-01-01

Full Text Available Excision of a suspected retroperitoneal, duodenal duplication cyst was performed in a pre-operatively normotensive patient under combined epidural and general anaesthesia. Intraoperatively, the cystic tumour was discovered to be a retroperitoneal mass, free from duodenal or adrenal origin. Development of severe arrhythmias, ST segment changes and hypertensive spikes during cyst handling and dissection suggested the possibility of a catecholamine-secreting tumour. These were managed effectively with pharmacological agents. Subsequently, histopathology of the specimen revealed a paraganglioma. Vasoactive tumour has to be suspected in every patient undergoing anaesthesia for retroperitoneal cystic lesion.

Bariatric surgery has been shown to be the most effective method of achieving weight loss and alleviating obesity-related comorbidities. Yet, it is not being used equitably. This study seeks to identify if there is a disparity in payer status of patients undergoing bariatric surgery and what factors are associated with this disparity. We performed a case-control analysis of National Inpatient Sample. We identified adults with body mass index (BMI) greater than or equal to 25 kg/m 2 who underwent bariatric surgery and matched them with overweight inpatient adult controls not undergoing surgery. The sample was analyzed using multivariate logistic regression. We identified 132,342 cases, in which the majority had private insurance (72.8%). Bariatric patients were significantly more likely to be privately insured than any other payer status; Medicare- and Medicaid-covered patients accounted for a low percentage of cases (Medicare 5.1%, OR 0.33, 95% CI 0.29-0.37, p bariatric surgery had an increased risk of complications compared to privately insured patients. Publicly insured patients are significantly less likely to undergo bariatric surgery. As a group, these patients experience higher rates of obesity and related complications and thus are most in need of bariatric surgery.

Aromatherapy has been used to reduce anxiety in a variety of settings, but usefulness associated with breast biopsies has not been documented. This study was conducted in women undergoing image-guided breast biopsy. We explored the use of two different aromatherapy scents, compared to placebo, aimed at reducing anxiety with the intent of generating new knowledge. This was a randomized, placebo-controlled study of two different types of external aromatherapy tabs (lavender-sandalwood and orange-peppermint) compared with a matched placebo-control delivery system. Anxiety was self-reported before and after undergoing a breast biopsy using the Spielberger State Anxiety Inventory Scale. Eighty-seven women participated in this study. There was a statistically significant reduction in self-reported anxiety with the use of the lavender-sandalwood aromatherapy tab compared with the placebo group (p = .032). Aromatherapy tabs reduced anxiety during image-guided breast biopsy. The completion of the biopsy provided some relief from anxiety in all groups. The use of aromatherapy tabs offers an evidence-based nursing intervention to improve adaptation and reduce anxiety for women undergoing breast biopsy. Lavender-sandalwood aromatherapy reduced anxiety and promoted adaptation more than orange-peppermint aromatherapy or placebo. © 2017 Sigma Theta Tau International.

Full Text Available Peritonitis is a common and life-threatening complication of acute peritoneal dialysis (PD. Diagnosis requires the presence of clinical signs of peritonitis which are nonspecific and laboratory investigations [total leukocyte count (TLC, Gram-stain, and culture of PD effluent fluid] which are time-consuming and not available at the bedside. In this study, we evaluated the use of leukocyte esterase reagent strip (LERS as a bedside test to diagnose peritonitis in patients undergoing acute PD. Patients who underwent acute PD were monitored for signs and symptoms of peritonitis. PD effluent fluid analysis included TLC, absolute neutrophil count, Gram-stain, and culture for the diagnosis of peritonitis. LERS (Multistix 10SG was simultaneously dipped in PD effluent fluid and read at two minutes. Reading of + was considered as indicative of peritonitis. Twenty-one out of 166 (12.6% patients undergoing acute PD developed peritonitis. LERS detected peritonitis in 20 patients. The sensitivity, specificity, positive predictive value, and negative predictive value (NPV of LERS were 95.2%, 95.2%, 74.1%, and 99.3%, respectively. LERS has very high sensitivity and NPV and can be used as a rapid bedside tool to exclude peritonitis in patients undergoing acute PD.

To assess the effect of virtual reality distraction on pain among patients with a hand injury undergoing a dressing change. Virtual reality distraction can effectively alleviate pain among patients undergoing a dressing change. Clinical research has not addressed pain control during a dressing change. A randomised controlled trial was performed. In the first dressing change sequence, 98 patients were randomly divided into an experimental group and a control group, with 49 cases in each group. Pain levels were compared between the two groups before and after the dressing change using a visual analog scale. The sense of involvement in virtual environments was measured using the Pearson correlation coefficient analysis, which determined the relationship between the sense of involvement and pain level. The difference in visual analog scale scores between the two groups before the dressing change was not statistically significant (t = 0·196, p > 0·05), but the scores became statistically significant after the dressing change (t = -30·792, p virtual environment and pain level during the dressing was statistically significant (R(2) = 0·5538, p Virtual reality distraction can effectively alleviate pain among patients with a hand injury undergoing a dressing change. Better results can be obtained by increasing the sense of involvement in a virtual environment. Virtual reality distraction can effectively relieve pain without side effects and is not reliant on a doctor's prescription. This tool is convenient for nurses to use, especially when analgesics are unavailable. © 2014 John Wiley & Sons Ltd.

2017-03-01

Full Text Available Introduction and objectives: The prevalence of preoperative state anxiety is an unavoidable complication. Aside from its type and scope, the surgical operation is considered as a severe stressful situation for patients. Considering the importance of reducing the state anxiety in patients undergoing surgery, there are different methods, one of which is patient education; therefore the aim of the current study was compare the effect of written and planned training on the state anxiety among patients undergoing orthopedic surgery. Method: In this study, 81 patients candidate for orthopedic surgery were selected using convenience sampling and were randomly divided into 3 groups, including planned training, pamphlet and control groups. All patients answered 20 questions-State-Traits Anxiety Inventory (STAI Questionnaire the day before surgery and the intervention was later carried out in the planned training and pamphlet groups. Then the effect of preoperative state anxiety was re-evaluated about half an hour after training in three groups. For data analysis, in addition to mean and standard deviation, independent t-test and ANOVA were used in Spss16. Results: The results of comparing pre- and post-training mean score of the state anxiety in three groups showed that the mean score of state anxiety reached from 50.41 to 41.03, 52.41 to 44.37 and 45.04 to 50.56 in planned, pamphlet and control groups, respectively. ANOVA test showed that there is a significant difference in this comparison. The results of Tukey's test also revealed that the mean score of state anxiety in the planned and pamphlet groups was lower significantly than the control group (p<0.05. Conclusion: Based on research findings, the planned training method was more effective in decreasing state anxiety among patients compared to the pamphlet group before orthopedic surgery. Therefore, considering the fact that nurses play an important role in examining and relieving the state anxiety

Rheumatoid arthritis (RA) is an autoimmune disorder characterized by progressive joint destruction that requires aggressive treatment using appropriate disease-modifying antirheumatic drugs (DMARDs). RA patients with renal failure, however, are intolerant to most DMARDs due to the potential toxicity. In Japan, tacrolimus was approved for the treatment of RA in 2005. Based on its pharmacokinetics, tacrolimus may be administered to the patients undergoing hemodialysis. We report two cases of RA patients on hemodialysis treated effectively and safely with tacrolimus.

Prosthetic joint infection (PJI) remains a major complication after total joint replacement and is the primary indication for revision arthroplasty. Specifically, coagulase-negative Staphylococci (CNS) can cause low-grade infections. Despite the use of cephalosporin-based antimicrobial prophylaxis (AMP) and antiseptic treatment at the surgical site, evidence suggests that a significant number of cases of dermal CNS results in low-grade PJI. Thus, this study examined the bacterial colonization and resistance patterns at the surgical site. We hypothesized that the bacteria developed resistance to antibiotics that are frequently used in primary and revision total hip arthroplasty (THA) procedures. Ninety patients, including 63 primary and 27 revision THA patients, were enrolled in this study. For each patient, a single swab of the skin at the surgical site was subjected to clinical microbiology to assess bacterial colonization. Furthermore, resistance to a sentinel panel of antibiotics (benzylpenicillin, erythromycin, tetracycline, oxacillin, fusidic acid, clindamycin, gentamicin, levofloxacin/moxifloxacin, rifampicin, linezolid and vancomycin) was tested. In 96.7% of the patients, at least one bacterial strain was identified at the surgical site, with CNS strains comprising 93.1% of the total. The sentinel panel showed that 30.7% of the CNS strains exhibited maximal resistance to oxacillin, a commonly used cephalosporin. Additionally, oxacillin resistance increased 1.9-fold (p=0.042) between primary and revision THA. Notably, 8.1% of the CNS stains found on patients undergoing primary THA were resistant to gentamicin, an aminoglycoside, and this rate increased 4.7-fold (p=0.001) for patients undergoing revision THA. CNS strains have significant resistance to standard AMP, particularly in individuals undergoing revision THA. Copyright© 2017, International Institute of Anticancer Research (Dr. George J.

Liver dysfunction increases death and morbidity after cardiac operations. There are currently no data evaluating liver function in patients undergoing transcatheter aortic valve replacement (TAVR). We aimed therefore to evaluate our TAVR results in regard to liver function. A total of 640 consecutive TAVR patients were evaluated. Of those, 11 patients presented with chronic liver disease before TAVR. The Model for End-Stage Liver Disease score was used to measure liver function in these patients. The primary study end point was 30-day mortality in patients presenting with liver dysfunction. Secondary study end point was liver enzymes after TAVR. The mean Model for End-Stage Liver Disease score in patients with chronic liver disease was 16.8 ± 6.2 (median, 18; range, 7 to 26). The 30-day mortality was 9.1% (57 of 629) in patients presenting without liver disease and 9.1% (1 of 11) in patients with liver disease (p = 1.00). Patients with chronic liver disease showed significantly higher preoperative levels of γ-glutamyl transpeptidase (p < 0.001). After TAVR, we observed a significant increase in alanine aminotransferase on postoperative day 3 compared with preoperative values (p < 0.001), accompanied by a decrease in albumin (p < 0.001). Liver cirrhosis per se is not considered as a contraindication for cardiac operations. In the present study, we did not observe a higher 30-day mortality rate in liver cirrhotic patients undergoing TAVR, suggesting TAVR as a feasible alternative with acceptable outcomes in patients with chronic liver disease. Moreover, the present study is the first to evaluate liver variables in patients undergoing TAVR. Copyright © 2017 The Society of Thoracic Surgeons. Published by Elsevier Inc. All rights reserved.

To evaluate the incidence of myoclonus (involuntary movements during anaesthesia, unrelated to inadequate hypnosis or analgesia, and of sufficient severity to require treatment) in dogs anaesthetized with a TIVA of propofol with or without the use of fentanyl. Retrospective clinical study. Dogs, undergoing general anaesthesia for clinical procedures between January 2012 and January 2013 and subject to TIVA with propofol. A retrospective analysis reviewed the medical and anaesthetic records. Animals with existing or potential neurological or neuromuscular pathology in the anamnesis or upon clinical examination and cases with incomplete clinical records were excluded. Myoclonus was considered as involuntary muscle contractions which did not cease following a bolus administration of propofol or fentanyl and, due to their intensity and duration, made continuation of the procedure impracticable without other drug administration. Tremors, paddling or muscle spasms, explicable as insufficient hypnosis or analgesia, and transient excitatory phenomena only present during the awakening phase, were not considered as myoclonus. Out of a total of 492 dogs undergoing anaesthesia, six mixed breed dogs (1.2%), one male and five females, American Society of Anaesthesiologists (ASA) physical status I, median (range) weight 20.5 (7-37) kg and age 1.5 (1-5) years had myoclonus according to the aforementioned definition. In all subjects, myoclonus appeared within 20 minutes after induction of anaesthesia, and mainly involved the limb muscles. All subjects appeared to be in an adequate plane of anaesthesia before and during myoclonus. This study shows that 1.2% of dogs, undergoing TIVA with propofol with or without fentanyl administration, developed myoclonus, which required to be, and were treated successfully pharmacologically. The cause of this phenomenon is yet to be determined. © 2014 Association of Veterinary Anaesthetists and the American College of Veterinary Anesthesia and

To identify the incidence and timing of venous thromboembolism as well as any associated risk factors in patients with ovarian, fallopian tube, or primary peritoneal cancer undergoing neoadjuvant chemotherapy. We conducted a retrospective cohort study of patients diagnosed with ovarian, fallopian tube, and primary peritoneal cancer and receiving neoadjuvant chemotherapy from January 2009 to May 2014 at a single academic institution. The timing and number of venous thromboembolic events for the entire cohort were categorized as follows: presenting symptom, during neoadjuvant chemotherapy treatment, after debulking surgery, and during adjuvant chemotherapy. Of the 125 total patients with ovarian cancer undergoing neoadjuvant chemotherapy, 13 of 125 patients (10.4%, 95% confidence interval [CI] 6.1-17.2%) had a venous thromboembolism as a presenting symptom and were excluded from further analysis. Of the 112 total patients at risk, 30 (26.8%, 95% CI 19.3-35.9%) experienced a venous thromboembolism. Based on the phase of care, 13 (11.6%, 95% CI 6.8-19.1%) experienced a venous thromboembolism during neoadjuvant chemotherapy, six (5.4%, 95% CI 2.4-11.5%) developed a postoperative venous thromboembolism, and 11 (9.9%, 95% CI 5.5-17%) developed a venous thromboembolism during adjuvant chemotherapy. Two of the four patients with clear cell histology developed a venous thromboembolism in this cohort. Overall new diagnosis of venous thromboembolism was associated with one fourth of the patients undergoing neoadjuvant chemotherapy for ovarian cancer with nearly half of these diagnosed during chemotherapy cycles before interval debulking surgery. Efforts to reduce venous thromboembolism so far have largely focused on the postoperative period. Additional attention to venous thromboembolic prophylaxis during chemotherapy (neoadjuvant and adjuvant) in this patient population is warranted in an effort to decrease the rates of venous thromboembolism.

To analyze the related influencing factors of urinary tract infection in patients undergoing transurethral resection of the prostate (TURP). A total of 343 patients with benign prostatic hyperplasia admitted to this hospital from January 2013 to December 2016, were selected and treated by TURP. Patients were divided into infection group and non-infection group according to the occurrence of urinary tract infection after operation. The possible influencing factors were collected to perform univariate and multivariate logistic regression analysis. There were 53 cases with urinary tract infection after operation among 343 patients with benign prostatic hyperplasia, accounting for 15.5%. The univariate analysis displayed that the occurrence of urinary tract infection in patients undergoing TURP was closely associated with patient's age ≥ 65 years old, complicated diabetes, catheterization for urinary retention before operation, no use of antibiotics before operation and postoperative indwelling catheter duration ≥ 5 d (p urinary tract infection in patients receiving TURP (p urinary tract infection after TURP, while preoperative prophylactic utilization of anti-infective drugs can reduce the occurrence of postoperative urinary tract infection.

The aim is to investigate ethnic variation, in presentation and biometric parameters, within the population undergoing cataract surgery in Auckland. The design is a retrospective study. Four thousand nine hundred thirty-one eyes of 3524 consecutive patients undergoing cataract surgery in Auckland Public Hospital over 18 months were included in the study. Analysis of preoperative medical records was performed. Age, gender, self-reported ethnicity, keratometry, anterior chamber depth, axial length and intraocular lens (IOL) power data were collected. Māori (4.7%) were under-represented compared with the proportion of Māori attending the eye clinic (5.5%) and in the major patient catchment area (8.2%). People of Māori, Pacific and Indian ethnicities presented at a significantly younger age (66.4, 65.9 and 67.9 years, respectively) than those of Caucasian and Asian ethnicities (76.4 and 71.3 years, respectively, P biometric parameters. These data may help identify potential biometric refinements and those at risk of developing ocular morbidities known to be associated with these parameters. © 2015 Royal Australian and New Zealand College of Ophthalmologists.

Full Text Available Аbstract.  Patients  with  end-stage  renal  disease  need  their  kidney  functions  to  be  replaced.  Chronic haemodialysis represents a most common method of such substitution treatment. This procedure results in successful survival of such patients for years. Chronic haemodialysis is accompanied by a complication which is known as β2-microglobulin amyloidosis. In this case, amyloid substance consisting of β2-microglobulin (β2-MG accumulates in bones, ligaments and joints. Biological causes of β2-MG amyloidosis are still not established. To elucidate the role of inflammation in the pathogenesis of β2-MG amyloidosis, the levels of  IL-2,  IL-4,  IL-6,  IL-8,  IL-10,  GM-CSF,  IFNγ, TNFα were quantified in plasma of patients undergoing  long-term haemodialysis. Mean amounts of all the mentioned cytokines in haemodialysis patients proved to be significantly higher than in control group consisting of healthy subjects. When comparing a group receiving standard  dialysis  procedure  versus  a  subgroup  receiving  haemodiafiltration,  a  single  reliable  difference  was revealed for GM-CSF levels (p < 0.04, without any differences shown for other cytokines. With increasing terms of chronic haemodialysis, the levels of IL-2, IL-4, IL-6, IL-8, GM-CSF, IFNγ, TNFα were increased, or, at least, they did not decrease. After three years of dialysis, IL-10 concentrations were statistically indistinguishable from normal levels. In patients undergoing haemodiafiltration, plasma levels of IL-2, IL-4, IL-8, GM-CSF, IFNγ, TNFα did not drop with increasing terms of dialysis. The levels of IL-6 and IL-10 decreased after three years of dialysis, to near-normal levels.In general, these results suggest that IL-10 and IL-6 may be regarded as candidates for further studies as potential markers of β2-microglobulin amyloidosis.

Blood conservation is an important aspect of care provided to the patients undergoing cardiac operations with cardiopulmonary bypass (CPB). It is even more important in patients with anticipated prolonged CPB, redo cardiac surgery, patients having negative blood group and in patients undergoing emergency cardiac surgery. In prolonged CPB the blood is subjected to more destruction of important coagulation factors, in redo surgery the separation of adhesions leads to increased bleeding and difficulty in achieving the haemostasis and in patients with negative blood group and emergency operations, the availability of sufficient blood can be a problem. Harvesting the autologous platelet rich plasma (PRP) can be a useful method of blood conservation in these patients. The above four categories of patients were prospectively studied, using either autologous whole blood donation or autologous platelet rich plasma (PRP) harvest in the immediate pre-bypass period. Forty two patients were included in the study and randomly divided into two equal groups of 21 each, control group (Group I) in which one unit of whole blood was withdrawn, and PRP group (Group II) where autologous plateletpheresis was utilised. After reversal of heparin, autologous whole blood was transfused in the control group and autologous PRP was transfused in the PRP group. The chest tube drainage and the requirement of homologous blood and blood products were recorded. Average PRP harvest was 643.33 +/- 133.51 mL in PRP group and the mean whole blood donation was 333.75 +/- 79.58 mL in the control group. Demographic, preoperative and intra operative data showed no statistically significant differences between the two groups. The PRP group patients drained 26.44% less (pblood products (pconservation in terms of better haemostasis, and less requirement of blood and blood products in the postoperative period as compared with the autologous whole blood donation. This technique can be especially useful in the

Mouth and pharyngeal cancers account for approximately 6% of cancers worldwide. Radiotherapy is one of the means of treatment of head and neck cancer. Consultation with a dental team experienced in caring for patients undergoing treatment for head and neck cancer will improve the quality of life of such patients. To evaluate the attitude of oncologists toward dental consultation to patients planning for/prior to/undergoing/post radiation therapy for head and neck cancers and to evaluate the number of radiation oncologists who encounter oral complaints and consider worth referring to a dentist. A questionnaire-based study was carried out following mailing of covering letter and self-administered questionnaire comprising 11 items, to 25 radiation oncology centers selected in India based on convenient sampling. Out of the 25 centers, we received response from 20 centers with 60 completely filled questionnaires. Five centers did not respond for further correspondences. The study indicated a need for awareness and education among radiation oncologists regarding dental consultation in patients planned/undergoing /post radiation therapy for head and neck cancer.

Full Text Available Background: Prolonged mechanical ventilation is an important recognized complication occurring during cardiovascular surgery procedures. This study was done to assess the perioperative risk factors related to postoperative pulmonary complications and tracheostomy in women undergoing coronary artery bypass graft with cardiopulmonary bypass. Methods: It was a retrospective study on 5,497 patients, including 31 patients with prolonged ventilatory support and 5,466 patients without it; from the latter group, 350 patients with normal condition (extubated in 6-8 hours without any complication were selected randomly. Possible perioperative risk factors were compared between the two groups using a binary logistic regression model. Results: Among the 5,497 women undergoing coronary artery bypass graft (CABG, 31 women needed prolonged mechanical ventilation (PMV, and 15 underwent tracheostomy. After logistic regression, 7 factors were determined as being independent perioperative risk factors for PMV. Discussion: Age ≥70 years old, left ventricular ejection fraction (LVEF ≤30%, preexisting respiratory or renal disease, emergency or re-do operation and use of preoperative inotropic agents are the main risk factors determined in this study on women undergoing CABG.

Beta-amyloid (Aβ) peptides are secreted from neurons, resulting in extracellular accumulation of Aβ and neurodegeneration of Alzheimer's disease. Because neuronal secretion is fundamental for the release of neurotransmitters, this study assessed the hypothesis that Aβ undergoes co-release with neurotransmitters. Model neuronal-like chromaffin cells were investigated, and results illustrate regulated, co-secretion of Aβ(1-40) and Aβ(1-42) with peptide neurotransmitters (galanin, enkephalin, and NPY) and catecholamine neurotransmitters (dopamine, norepinephrine, and epinephrine). Regulated secretion from chromaffin cells was stimulated by KCl depolarization and nicotine. Forskolin, stimulating cAMP, also induced co-secretion of Aβ peptides with peptide and catecholamine neurotransmitters. These data suggested the co-localization of Aβ with neurotransmitters in dense core secretory vesicles (DCSV) that store and secrete such chemical messengers. Indeed, Aβ was demonstrated to be present in DCSV with neuropeptide and catecholamine transmitters. Furthermore, the DCSV organelle contains APP and its processing proteases, β- and γ-secretases, that are necessary for production of Aβ. Thus, Aβ can be generated in neurotransmitter-containing DCSV. Human IMR32 neuroblastoma cells also displayed regulated secretion of Aβ(1-40) and Aβ(1-42) with the galanin neurotransmitter. These findings illustrate that Aβ peptides are present in neurotransmitter-containing DCSV, and undergo co-secretion with neuropeptide and catecholamine neurotransmitters that regulate brain functions.

Music therapy, an innovative approach that has proven effectiveness in many medical conditions, seems beneficial also in managing surgical patients. The aim of this study is to evaluate its effects, under general anesthesia, on perioperative patient satisfaction, stress, pain, and awareness. This is a prospective, randomized, double-blind study conducted in the operating theatre of visceral surgery at Sahloul Teaching Hospital over a period of 4 months. Patients aged more than 18 undergoing a scheduled surgery under general anesthesia were included. Patients undergoing urgent surgery or presenting hearing or cognitive disorders were excluded. Before induction, patients wore headphones linked to an MP3 player. They were randomly allocated into 2 groups: Group M (with music during surgery) and group C (without music). Hemodynamic parameters, quality of arousal, pain experienced, patient's satisfaction, and awareness incidence during anesthesia were recorded. One hundred and forty patients were included and allocated into 2 groups that were comparable in demographic characteristics, surgical intervention type and anesthesia duration. Comparison of these two groups regarding the hemodynamic profile found more stability in group M for systolic arterial blood pressure. A calm recovery was more often noted in group M (77.1% versus 44%, p Music therapy is a non-pharmacological, inexpensive, and non-invasive technique that can significantly enhance patient satisfaction and decrease patients' embarrassing experiences related to perioperative stress, pain, and awareness.

Full Text Available PURPOSE: To evaluate the conjunctival bacterial flora and its antibiotic resistance pattern in eyes of patients undergoing cataract surgery. METHODS: From August to October 2004, 50 patients undergoing cataract surgery in the "Fundação Altino Ventura", Recife, Brazil, were prospectively evaluated. Conjunctival material was obtained on the day of surgery, before the application of topical anesthetic, antibiotic or povidone-iodine. The collected material was inoculated and bacterioscopic analysis was carried out. In the cases where there was bacterial growth, antibiotic susceptibility tests and cultures, for isolation and identification of the bacteria, were performed. RESULTS: Of the 50 eyes, 43 (86.0% had positive cultures. The coagulase-negative Staphylococcus (CNS, found in 27 (54.0% eyes, was the most frequent organism. More than 90% of the isolates of this bacterium were susceptible to cephalotin, vancomycin, chloramphenicol, ofloxacin and gatifloxacin; 70 to 90% were susceptible to gentamicin, cefotaxime, oxacillin and ciprofloxacin; and less than 70% were sensible to neomycin. Four (10.5% of the bacterial isolates were resistant to four or more antibiotics, two of them were CNS. CONCLUSION: The most frequent bacterium in the conjunctival flora is the coagulase-negative Staphylococcus. The isolates of this organism showed low susceptibility rate to neomycin, and high susceptibility rates to cephalotin, vancomycin, chloramphenicol, ofloxacin and gatifloxacin.

Full Text Available Purpose: To investigate the possible effects of the fetal echocardiography experience on the prenatal attachment process. The predictive effect of specific women’s psychological variables will be explored as well.Design and methods: This between groups study involved 85 women with pregnancy at risk who underwent the fetal echocardiography, and 83 women who were about to undergo the morphological scan. The tools employed were: the Prenatal Attachment Inventory (P.A.I. to explore the maternal-fetal attachment; the Maternity Social Support Scale to investigate the woman perception of being socially supported during pregnancy; both the Big Five Questionnaire and the FACES III to explore the personality traits of pregnant women and their perception of their couple relationship functioning.Findings: The outcomes of ANOVA do not show statistically significant differences between the two groups of the mothers-to-be with regard to the scores of the P.A.I. (F = .017; p = .897; η2 = .000, while the regression analysis of the possible effect of the maternal psychological variables on the mother-fetus relationship shows a statistically significant result only with regard to the “social support” variable (r2 = .061; df = 80; p = .025.Conclusions: It would seem that the process of the prenatal attachment develops independently whether the woman has to undergo a first level screening or a second level examination such as the fetal echocardiography.

Full Text Available Purpose: General anesthesia causes inhibition of thermoregulatory mechanisms. Propofol has been reported to cause more temperature fall, but in case of deliberate mild hypothermia, both sevoflurane and propofol were comparable. Thermoregulation is found to be disturbed in cases of pituitary tumors. We aimed to investigate which of the two agents, sevoflurane or propofol, results in better preservation of thermoregulation in patients undergoing transsphenoidal excision of pituitary tumors. Methods: Twenty-six patients scheduled to undergo transsphenoidal removal of pituitary adenomas were randomly allocated to receive propofol or sevoflurane anesthesia. Baseline esophageal temperature was noted. Times for temperature to fall by 1°C or 35°C and to return to baseline were also comparable ( P>0.05. After that warmer was started at 43°C and time to rise to baseline was noted. Duration of surgery, total blood loss, and total fluid intake were also noted. If any, side effects such as delayed arousal and recovery from muscle relaxant were noted. Results: The demographics of the patients were comparable. Duration of surgery and total blood loss were comparable in the two groups. The time for temperature to fall by 1°C or 35°C and time to return to baseline was also comparable ( P>0.05. No side effects related to body temperature were noted. Conclusion: Both propofol and sevoflurane show similar effects in maintaining thermal homeostasis in patients undergoing transsphenoidal pituitary surgery.

The prognostic value of cystatin C (CysC) has been documented in patients with acute coronary syndrome without ST-segment elevation. However, its value in acute ST-segment elevation myocardial infarction (STEMI) remains unclear. The aim of this study was to evaluate the prognostic value of CysC in patients with STEMI undergoing primary percutaneous coronary intervention (PCI). We prospectively enrolled 475 consecutive STEMI patients (mean age 55.6±12.4 years, 380 male, 95 female) undergoing primary PCI. The study population was divided into tertiles based on admission CysC values. The high CysC group (n=159) was defined as a value in the third tertile (>1.12 mg/L), and the low CysC group (n=316) included those patients with a value in the lower two tertiles (≤1.12 mg/L). Clinical characteristics and in-hospital and one-month outcomes of primary PCI were analyzed. The patients of the high CysC group were older (mean age 62.8±13.1 vs. 52.3±10.5, P1.12 mg/L) was found to be a powerful independent predictor of one-month cardiovascular mortality (odds ratio, 5.3; 95% confidence interval, 1.25-22.38; P=.02). These results suggest that a high admission CysC level was associated with increased in-hospital and one-month cardiovascular mortality in patients with STEMI undergoing primary PCI.

The prognostic value of D-dimer has been documented in patients with acute coronary syndrome without ST-segment elevation. However, its value in acute ST-segment elevation myocardial infarction (STEMI) remains unclear. We prospectively enrolled 453 consecutive STEMI patients (mean age 55.6 ± 12.4 years, 364 male, 89 female) undergoing primary PCI. The study population was divided into tertiles based on admission D-dimer values. The high D-dimer group (n = 151) was defined as a value in the third tertile [>0.72 ug/ml fibrinogen equivalent units (FEU)], and the low D-dimer group (n = 302) included those patients with a value in the lower two tertiles (≤0.72 ug/ml FEU). Clinical characteristics, in-hospital and 6-month outcomes of primary PCI were analyzed. The patients of the high D-dimer group were older (mean age 60.1 ± 13.5 versus 52.4 ± 10.6, P 0.72 ug/ml FEU) was found to be a powerful independent predictor of 6-month all-cause mortality (odds ratio: 10.1, 95% confidence interval: 1.24-42.73, P = 0.03). These results suggest that a high admission D-dimer, level was associated with increased in-hospital cardiovascular mortality and 6-month all-cause mortality in patients with STEMI undergoing primary PCI.

Full Text Available Objective: Evaluate the ability of clonidine to reduce pulmonary arterial pressure in patients with pulmonary hypertension undergoing heart surgery, either by reducing the pressure values from the direct measurement of pulmonary arterial pressure or by reducing or eliminating the need for intraoperative dobutamine and nitroprusside. Method: Randomized, double-blind, placebo-controlled, comparative study conducted in 30 patients with pulmonary arterial hypertension type 2 undergoing cardiac surgery. Mean pulmonary arterial pressure and dosage of dobutamine and sodium nitroprusside were assessed four times: before intravenous administration of clonidine (2 μg/kg or placebo (T0, 30 min after tested treatment and before cardiopulmonary bypass (T1, immediately after CPB (T2, 10 min after protamine injection (T3. Results: There were no significant differences regarding mean pulmonary arterial pressure at any time of evaluation. There was no significant difference between groups regarding other variables, such as mean systemic arterial pressure, heart rate, total dose of dobutamine, total dose of sodium nitroprusside, and need for fentanyl. Conclusion: Data analysis from patients included in this study allows us to conclude that intravenous clonidine (2 μg/kg was not able to reduce the mean pulmonary arterial pressure in patients with pulmonary hypertension in group 2 (pulmonary venous hypertension, undergoing heart surgery, or reduce or eliminate the need for intraoperative administration of dobutamine and sodium nitroprusside.

Petrenko, Natalia; Jin, Yi; Wong, Koon Ho; Struhl, Kevin

2016-11-03

Mediator is a transcriptional co-activator recruited to enhancers by DNA-binding activators, and it also interacts with RNA polymerase (Pol) II as part of the preinitiation complex (PIC). We demonstrate that a single Mediator complex associates with the enhancer and core promoter in vivo, indicating that it can physically bridge these transcriptional elements. However, the Mediator kinase module associates strongly with the enhancer, but not with the core promoter, and it dissociates from the enhancer upon depletion of the TFIIH kinase. Severing the kinase module from Mediator by removing the connecting subunit Med13 does not affect Mediator association at the core promoter but increases occupancy at enhancers. Thus, Mediator undergoes a compositional change in which the kinase module, recruited via Mediator to the enhancer, dissociates from Mediator to permit association with Pol II and the PIC. As such, Mediator acts as a dynamic bridge between the enhancer and core promoter. Copyright © 2016 Elsevier Inc. All rights reserved.

Venous thrombolembolism is one of the major postoperative complications in patients undergoing total hip replacement (THR) or knee anthroplasty (TKA). The reported incidence of pulmonary embolism in this group is as high as 20%. The purpose of this report was to evaluate the value of preoperative and 7th-day postpoperative ventilation-perfusion (V/Q) lung scans in the management of patients undergoing elective reconstructive surgery of the hips or knees. Routine preoperative and 7th-day postoperative V/Q lung scans were obtained in 34 patients who underwent THR (17 patients) or TKA (17 patients). There were 15 male and 19 female patients, with an age distribution ranging from 56 to 80 years. Chest radiographs were obtained within 1 day of the pre- or postoperative lungs scan. Lung scans were interpreted by two experienced nuclear physicians

Full Text Available Background Infertility treatment is a long-term process, spread out over months, or even years, and carries no guarantee of success. It generates an incessant state of uncertainty which becomes a chronic state of psychological discomfort. Each stage of treatment may become a source of more trouble. Women deciding to undergo infertility treatment are exposed to many negative feelings concerning different aspects of their life. Participants and procedure The present study was an attempt to understand psychological determinants of life satisfaction in women undergoing infertility treatment. The study group included 470 women treated for infertility. Results Patients perceiving more social support in general, as well as more of the support types used in the study, i.e. emotional, instrumental, informational and institutional support, and support from family and friends, have better self-esteem, higher acceptance of their infertility, higher satisfaction with life, higher hope as an emotional state, and lower levels of anxiety and depression. Three negative emotional states, i.e. anxiety, depression and irritation, are predictors influencing (lowering life satisfaction of women struggling with infertility. The strongest of these predictors is depression, which is also a factor lowering the acceptance of one’s own infertility. The conducted analyses revealed that predictors influencing the life satisfaction of patients treated for infertility are self-esteem and acceptance of one’s own infertility (apart from the aforementioned emotional state – anxiety, depression, irritation. It was found that the higher the self-esteem and acceptance of one’s own infertility, the higher was the satisfaction with life. Conclusions Knowledge of these determinants is extremely valuable for medical personnel conducting treatments, because, according to many studies, the psychological state of women suffering from procreation problems is connected not only with

Coral bleaching is a major threat to coral reefs worldwide and is predicted to intensify with increasing global temperature. This study represents the first investigation of gene expression in an Indo-Pacific coral species undergoing natural bleaching which involved the loss of algal symbionts. Quantitative real-time polymerase chain reaction experiments were conducted to select and evaluate coral internal control genes (ICGs), and to investigate selected coral genes of interest (GOIs) for changes in gene expression in nine colonies of the scleractinian coral Acropora millepora undergoing bleaching at Magnetic Island, Great Barrier Reef, Australia. Among the six ICGs tested, glyceraldehyde 3-phosphate dehydrogenase and the ribosomal protein genes S7 and L9 exhibited the most constant expression levels between samples from healthy-looking colonies and samples from the same colonies when severely bleached a year later. These ICGs were therefore utilised for normalisation of expression data for seven selected GOIs. Of the seven GOIs, homologues of catalase, C-type lectin and chromoprotein genes were significantly up-regulated as a result of bleaching by factors of 1.81, 1.46 and 1.61 (linear mixed models analysis of variance, P coral bleaching response genes. In contrast, three genes, including one putative ICG, showed highly variable levels of expression between coral colonies. Potential variation in microhabitat, gene function unrelated to the stress response and individualised stress responses may influence such differences between colonies and need to be better understood when designing and interpreting future studies of gene expression in natural coral populations.

2016-12-01

This exploratory study provides insights into everyday realities, concerns, and cultural perspectives of Latinas undergoing chemotherapy, and elicits information on stress management and information needs. Informed by a community-based participatory research approach using qualitative methods, we conducted ten interviews with providers, and two focus groups (n = 13) and 20 in-depth interviews with Latinas recently diagnosed with breast cancer. Providers and Latina patients acknowledged multiple physical and emotional stressors associated with cancer treatment, viewed a positive aspect of the cancer experience to include connection with God and enhanced spirituality, saw family as a motivating factor for recovery, and expressed a need to draw on existing coping strategies. Findings show considerable overlap between providers and Latina cancer patients' perceptions of stressors during chemotherapy. However, a few notable differences in perceptions of stress management needs during this treatment period emerged. While Latina cancer patients mentioned similar social/structural stressors (e.g., economic problems, lack of information) they tended to emphasize more of the interpersonal stressors related to family communication and relationships (e.g., providing and caring for family, distance from family), and intrapersonal stressors such as fear, changes in physical appearance, and side effects of chemotherapy. Our study illustrates the importance of including multiple perspectives. The information gained by including both providers and patient perspectives yielded a more complete understanding of the stress management needs of Latinas undergoing chemotherapy. Findings suggest that stress management educational interventions should aim to develop self-care skills, be culturally relevant and language-specific, and build upon stress-reducing strategies Latinas may already employ.

Coronary artery disease occurs frequently in patients undergoing aortic reconstruction, and it has been presumed that internal carotid artery occlusive disease is also common. This has led to the practice of screening for and repairing significant carotid lesions in asymptomatic patients prior to aortic reconstruction. The purpose of this study was to determine the true prevalence of internal carotid artery disease in these patients. The records of 240 patients who underwent duplex ultrasound screening for carotid artery disease prior to aortic reconstruction were reviewed. Surgery was performed for aortic aneurysm (AA) or aorto-iliac occlusive disease (AO). The prevalence of hyperlipidemia and coronary artery disease was similar between the two groups, but tobacco use, hypertension, and diabetes mellitus differed. Internal carotid artery stenosis > or = 50% occurred in 26.7% of the total group (64 of 240 cases). Stenosis > or = 50% was more common in the AO group (40 of 101 cases, 39.6%) than the AA group (24 of 139 cases, 17.3%, P = 0.0001). Severe disease (70% to 99%) was also more common in the AO group than the AA group (9.9% versus 3.6%, P = 0.0464). Internal carotid artery disease occurs commonly in patients undergoing aortic reconstruction, and screening is worthwhile. Significant disease is more common in patients with aorto-iliac occlusive disease than in those with aortic aneurysm, although atherosclerotic risk factors occur with varying frequency in the two groups. These findings suggest that additional factors may contribute to the higher prevalence of internal carotid artery stenosis in aorto-iliac occlusive disease.

DIDS is a unique form of combined immune deficiency characterized by an unusual susceptibility to cutaneous viral infections, severe allergies with eosinophilia and elevated immunoglobulin E titers, autoimmunity, and cancer. HSCT is considered the standard of care for this deadly disease. We have retrospectively analyzed the outcome of allogeneic HSCT from unrelated donors in patients with DIDS. Data from four patients, with five transplants, are presented. All patients received transplants from unrelated donors' BM, except for one patient who received a cord blood transplant. The conditioning regimens were based on myeloablative protocols for BM derived transplants; a NM regimen was pursued for the patient who received a cord blood transplant, which resulted in graft rejection. Although recurrent pneumonia and skin infections resolved immediately after transplantation, all patients subsequently developed human herpesvirus infection, including cutaneous herpetic lesions, cytomegalovirus reactivation, and zona zoster, which could be attributed to the use of ATG. Despite the presence of serious morbidities prior to transplantation, all patients recovered successfully. DIDS can be successfully treated with allogeneic HSCT from unrelated donors following a myeloablative conditioning regimen, with a reasonable safety profile. © 2017 John Wiley & Sons A/S.

Hemodialysis (HD) patients have been increasing recently. Some rheumatoid arthritis (RA) patients need hemodialysis (HD), though the proportion is not high. At present, such patients are almost treated with corticosteroids and/or nonsteroidal anti-inflammatory drugs alone, even if they have a high disease activity that would require disease-modifying anti-rheumatic drug (DMARD) therapy, partly because the safety of DMARDs in RA patients with end-stage renal disease has not been confirmed. Their joint destruction would be inevitable and lead to impaired activities of daily living. As there are no guidelines for the use of DMARDs in HD patients, here I reviewed the previous reports about the treatment of DMARDs including biologics for patients with RA undergoing HD.

2018-01-01

Full Text Available Purpose: Functional characteristics and durability of the artificial urinary sphincter (AUS among patients who develop bladder cancer has been poorly characterized. We sought to evaluate AUS outcomes among patients subsequently diagnosed with bladder cancer, in order to describe device survivability when subject to diagnostic and therapeutic procedures such as cystoscopy, transurethral resection, and cystectomy. Materials and Methods: We retrospectively reviewed 1,803 male patients treated with AUS surgery at a single institution between 1983–2014. We describe AUS device outcomes among patients undergoing surveillance and treatment for bladder cancer. Results: Following AUS placement, 14 (0.8% patients were subsequently diagnosed with and treated for bladder cancer and 4 patients with bladder cancer undergoing treatment and screening, subsequently received AUS placement. The median follow-up from device placement was 7.2 years (interquartile range [IQR], 2.8–11.5, and the median time from AUS placement to bladder cancer diagnosis was 6 (IQR, 0–9. There were a total of 8 primary and 1 secondary devices failures. Despite a median of 2 diagnostic cystoscopies (IQR, 1–6 and 0 bladder tumor resections (IQR, 0–0 per patient following device implantation, only 1 (5.6% patient experienced an iatrogenic erosion related to urethral manipulation. Among those undergoing cystectomy (n=4, 1 device was left in situ without complication. Conclusions: Bladder cancer surveillance and treatment with an AUS device in place appears to confer minimal additional risk to AUS survival. Careful attention should be given to device deactivation and use of the smallest caliber instruments available to minimize the risk of iatrogenic urethral erosion.

Nonlinear analysis of flexible beams undergoing large rotations Via symbolic computations

Directory of Open Access Journals (Sweden)

Yuan Xiaofeng

2001-01-01

Full Text Available In this paper, a two-stage approach is presented for analyzing flexible beams undergoing large rotations. In the first stage, the symbolic forms of equations of motion and the Jacobian matrix are generated by means of MATLAB and written into a MATLAB script file automatically, where the flexible beams are described by the unified formulation presented in our previous paper. In the second stage, the derived equations of motion are solved by means of implicit numerical methods. Several comparison computations are performed. The two-stage approach proves to be much more efficient than pure numerical one.

To evaluate the effects of perioperative oral administration of carprofen and meloxicam on concentrations of 3 acute-phase proteins in dogs undergoing elective ovariohysterectomy (OVH). 18 healthy adult anestrous female dogs undergoing elective OVH. Dogs were allocated to 3 groups (6 dogs/group). A placebo treatment, carprofen (2.0 mg/kg), or meloxicam (0.2 mg/kg) was orally administered to the dogs of the respective groups. The initial doses were administered 30 minutes before premedication prior to OVH; additional doses were administered once daily for 4 days after surgery. Blood samples were collected 45 minutes before premedication and 4, 8, 12, 24, 36, 48, 72, 96, and 120 hours after the end of OVH; samples were used for measurement of total WBC and neutrophil counts and concentrations of C-reactive protein (CRP), ceruloplasmin, and fibrinogen. Values did not differ significantly among groups for WBC and neutrophil counts, serum concentrations of CRP and ceruloplasmin, and plasma concentrations of fibrinogen. Concentrations of all inflammatory markers, except serum ceruloplasmin, increased significantly following OVH, but in a similar manner for each group. No significant changes were detected in serum ceruloplasmin concentrations over time. Perioperative administration of both carprofen and meloxicam did not significantly affect the concentrations of CRP, ceruloplasmin, and fibrinogen in dogs undergoing OVH. Thus, use of carprofen or meloxicam should not affect clinical interpretation of results for these 3 acute-phase proteins.

To investigate the effect of an on-site prototype metal artefact reduction (MAR) algorithm in cone-beam CT-catheter-arteriography (CBCT-CA) in patients undergoing transarterial radioembolisation (RE) of hepatic masses. Ethical board approved retrospective study of 29 patients (mean 63.7±13.7 years, 11 female), including 16 patients with arterial metallic coils, undergoing CBCT-CA (8s scan, 200 degrees rotation, 397 projections). Image reconstructions with and without prototype MAR algorithm were evaluated quantitatively (streak-artefact attenuation changes) and qualitatively (visibility of hepatic parenchyma and vessels) in near- (<1cm) and far-field (>3cm) of artefact sources (metallic coils and catheters). Quantitative and qualitative measurements of uncorrected and MAR corrected images and different artefact sources were compared Quantitative evaluation showed significant reduction of near- and far-field streak-artefacts with MAR for both artefact sources (p<0.001), while remaining stable for unaffected organs (all p>0.05). Inhomogeneities of attenuation values were significantly higher for metallic coils compared to catheters (p<0.001) and decreased significantly for both after MAR (p<0.001). Qualitative image scores were significantly improved after MAR (all p<0.003) with by trend higher artefact degrees for metallic coils compared to catheters. In patients undergoing CBCT-CA for transarterial RE, prototype MAR algorithm improves image quality in proximity of metallic coil and catheter artefacts. (orig.)

Gamble, Lisa M.; Farrell, Thomas J.; Jones, Glenn W.; Hayward, Joseph E.

2005-01-01

Purpose: To demonstrate the viability of radiochromic film as an in vivo, two-dimensional dosimeter for the measurement of underdosed areas in patients undergoing total skin electron beam (TSEB) radiotherapy. The results were compared with thermoluminescent dosimeter measurements. Methods and Materials: Dosimetry results are reported for an inframammary fold of 2 patients treated using a modified version of the Stanford six-position (i.e., six-field and dual-beam) TSEB technique. The results are presented as contour plots of film optical density and percentage of dose. A linear dose profile measured from film was compared with the thermoluminescent dosimeter measurements. Results: The results showed that the percentage doses as measured by film are in good agreement with those measured by the thermoluminescent dosimeters. The isodose contour plots provided by film can be used as a two-dimensional dose map for a patient when determining the size of the supplemental patch fields. Conclusion: Radiochromic film is a viable dosimetry tool that the radiation oncologist can use to understand the surface dose heterogeneity better across complex concave regions of skin to help establish more appropriate margins to patch underdosed areas. Film could be used for patients undergoing TSEB for disorders such as mycosis fungoides or undergoing TSEB or regional skin electron beam for widespread skin metastases from breast cancer and other malignancies

Anita Joselyn

2015-01-01

Full Text Available Purpose: One of the major advantages for patients undergoing minimally invasive surgery as compared to an open surgical procedure is the improved recovery profile and decreased opioid requirements in the perioperative period. There are no definitive studies comparing the analgesic requirements in patients undergoing two different types of minimally invasive procedure. This study retrospectively compares the perioperative analgesic requirements in severely obese adolescents and young adults undergoing laparoscopic versus robotic-assisted, laparoscopic gastric sleeve resection. Materials and Methods: With Institutional Review Board approval, the medication administration records of all severely obese patients who underwent gastric sleeve resection were retrospectively reviewed. Intra-operative analgesic and adjuvant medications administered, postoperative analgesic requirements, and visual analog pain scores were compared between those undergoing a laparoscopic procedure versus a robotic-assisted procedure. Results: This study cohort included a total of 28 patients who underwent gastric sleeve resection surgery with 14 patients in the laparoscopic group and 14 patients in the robotic-assisted group. Intra-operative adjuvant administration of both intravenous acetaminophen and ketorolac was similar in both groups. Patients in the robotic-assisted group required significantly less opioid during the intra-operative period as compared to patients in the laparoscopic group (0.15 ± 0.08 mg/kg vs. 0.19 ± 0.06 mg/kg morphine, P = 0.024. Cumulative opioid requirements for the first 72 postoperative h were similar in both the groups (0.64 ± 0.25 vs. 0.68 ± 0.27 mg/kg morphine, P = NS. No difference was noted in the postoperative pain scores. Conclusion: Although intraoperative opioid administration was lower in the robotic-assisted group, the postoperative opioid requirements, and the postoperative pain scores were similar in both groups.

We sought to develop a predictive model based exclusively on preoperative factors to identify patients at risk for PrlICULOS following coronary artery bypass grafting (CABG). Retrospective analysis was performed on patients undergoing isolated CABG at a single center between June 1998 and December 2002. PrlICULOS was defined as initial admission to ICU exceeding 72 h. A parsimonious risk-predictive model was constructed on the basis of preoperative factors, with subsequent internal validation. Of 3483 patients undergoing isolated CABG between June 1998 and December 2002, 411 (11.8%) experienced PrlICULOS. Overall in-hospital mortality was higher among these patients (14.4% vs. 1.2%, Prisk predictive model of PrlICULOS in patients undergoing CABG was constructed. Based on preoperative clinical factors, a scorecard was developed allowing identification of these patients prior to surgery and allowing for strategies aimed at optimizing hospital resources.

Radiotherapy is one of the primary treatment strategies for cancer. However, patients not only deal with the side-effects of radiotherapy, but they must also endure the psychological distress caused by cancer. This study explores how cancer patients adapt to the treatment process when receiving radiotherapy. This study used a grounded theory approach, and eight in-depth interviews were conducted with newly diagnosed cancer patients who received radiotherapy as a primary treatment. The core category that emerged from this study was "the desire to survive". The categories and subcategories that emerged from the data include facing unknown situations (e.g. searching for relevant information and decision-making considerations, and listening to healthcare professionals' suggestions), experiencing the pain of treatment (e.g. tolerating side-effects, tolerating inconvenience during the treatment, accepting support during the treatment, and adjusting lifestyles), and chances to extend life (e.g. accepting fate, determination to undergo the treatment, and adjusting negative emotions). The study results provide a better understanding of the experiences of cancer patients undergoing radiotherapy. Healthcare professionals should provide effective medical management for side-effects and psychological support to cancer patients during the journey of radiotherapy. © 2014 The Authors.

A simple, objective and accurate way of grouping children undergoing surgery into clinically relevant risk groups is needed. The purpose of this study, is to develop and validate a preoperative risk classification system for postsurgical 30-day mortality for children undergoing a wide variety of operations. The National Surgical Quality Improvement Project-Pediatric participant use file data for calendar years 2012–2014 was analyzed to determine preoperative variables most associated with death within 30 days of operation (D30). Risk groups were created using classification tree analysis based on these preoperative variables. The resulting risk groups were validated using 2015 data, and applied to neonates and higher risk CPT codes to determine validity in high-risk subpopulations. A five-level risk classification was found to be most accurate. The preoperative need for ventilation, oxygen support, inotropic support, sepsis, the need for emergent surgery and a do not resuscitate order defined non-overlapping groups with observed rates of D30 that vary from 0.075% (Very Low Risk) to 38.6% (Very High Risk). When CPT codes where death was never observed are eliminated or when the system is applied to neonates, the groupings remained predictive of death in an ordinal manner. PMID:29351327

This study compares the performance of the logistic regression and decision tree analysis methods for assessing the risk factors for infection in cancer patients undergoing chemotherapy. The subjects were 732 cancer patients who were receiving chemotherapy at K university hospital in Seoul, Korea. The data were collected between March 2011 and February 2013 and were processed for descriptive analysis, logistic regression and decision tree analysis using the IBM SPSS Statistics 19 and Modeler 15.1 programs. The most common risk factors for infection in cancer patients receiving chemotherapy were identified as alkylating agents, vinca alkaloid and underlying diabetes mellitus. The logistic regression explained 66.7% of the variation in the data in terms of sensitivity and 88.9% in terms of specificity. The decision tree analysis accounted for 55.0% of the variation in the data in terms of sensitivity and 89.0% in terms of specificity. As for the overall classification accuracy, the logistic regression explained 88.0% and the decision tree analysis explained 87.2%. The logistic regression analysis showed a higher degree of sensitivity and classification accuracy. Therefore, logistic regression analysis is concluded to be the more effective and useful method for establishing an infection prediction model for patients undergoing chemotherapy.

Health-related quality of life (HRQOL) reflects the general well-being of individuals. In patients with coronary artery disease (CAD), HRQOL is compromised. Female patients with CAD have been reported to have lower HRQOL. In this study, we investigate gender differences in HRQOL and in associations of patient characteristics with HRQOL in patients with coronary angiography (CAG). We cross-sectionally analysed patients from the Utrecht Coronary Biobank undergoing CAG. All patients filled in an HRQOL questionnaire (RAND-36 and EuroQoL) on inclusion. RAND-36 and EuroQoL HRQOL measures were compared between the genders across indications for CAG, CAD severity and treatment of CAD. RAND-36 HRQOL measures were compared with the general Dutch population. Additionally, we assessed interactions of gender with patient characteristics in their association with HRQOL (EuroQoL). We included 1421 patients (1020 men and 401 women) with a mean age of 65 in our analysis. Women reported lower HRQOL measures than men (mean EuroQoL self-rated health grade 6.84±1.49 in men, 6.46±1.40 in women, pgender differences were found in determinants of HRQOL in patients undergoing CAG, which deserve attention in future research.

Merve Mese

2015-01-01

Full Text Available The purpose of this case report was to present the multidisciplinary management of a subgingival crown-root fracture of a patient undergoing apexification treatment. A 12-year-old male patient was referred to the pediatric dentistry clinic with an extensive tooth fracture of the right permanent maxillary lateral incisor. Clinical and radiographic examinations revealed the presence of a complicated crown-root fracture, which had elongated to the buccal subgingival area. The dental history disclosed that the apexification procedure had been started to be performed after his first trauma experience and he had neglected his appointment. The coronal fragment was gently extracted; endodontic treatment was performed; flap surgery was performed to make the fracture line visible. The coronal fragment was reattached to the root fragment with a dual-cure luting composite. A fiber post was stabilized and the access cavity of the tooth was restored with composite resin. At the end of the 24th month, the tooth was asymptomatic, functionally, esthetically acceptable and had no periapical pathology. It is important for the patients undergoing apexification treatment to keep their appointments because of the fracture risk. Restoration of the fractured tooth by preparing retention grooves and a bonding fiber-reinforced post are effective and necessary approaches for successful management.

In patients undergoing elective partial pancreatectomy, our aim was to evaluate the effect of metabolic syndrome (MS) on postoperative mortality, morbidity, and utilization of hospital resources. Our hypothesis was that MS is associated with worse surgical outcomes after pancreatectomy. Fifteen thousand eight hundred thirty-one patients undergoing elective pancreatectomy from 2005 to 2012 were identified in the Participant User File of the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP). Univariable and multivariable analyses were performed examining the association of MS (defined as body mass index ≥30 kg/m(2), hypertension requiring medications, and diabetes requiring medications and/or insulin) and risk of 30-day mortality, morbidity, and utilization of hospital resources (risk of blood transfusion in the first 72 h after pancreatectomy and prolonged hospital stay, defined as ≥13 days, which was the 75th percentile of this cohort). Multivariable logistic regression models controlled for age, sex, race, pancreatectomy type (distal versus proximal), smoking status, alcohol consumption, functional status, dyspnea, cardiovascular disease, hematocrit, INR, serum albumin, bilirubin, and creatinine. Stratified analyses were conducted by type of pancreatectomy and indication for pancreatectomy (benign versus malignant). On univariate analysis, 1070 (6.8%) patients had MS. MS was associated with increased postoperative morbidity, major morbidity, surgical site infection, septic shock, cardiac event, respiratory failure, pulmonary embolism, blood transfusion, and prolonged duration of hospital stay (P pancreatectomy (P = 0.465). When stratified by distal versus proximal pancreatectomy and benign versus malignant disease, the effect of MS on outcomes appears to be modified by type of pancreatectomy and indication with poorer outcomes observed for distal pancreatectomies and benign indications for resection. MS is an under

Severe obesity in childhood is a major health problem with few effective treatments. Weight-loss surgery (WLS) is being used to treat severely obese adolescents, although with very limited data regarding surgical safety for currently used, minimally invasive procedures. To assess the preoperative clinical characteristics and perioperative safety outcomes of severely obese adolescents undergoing WLS. This prospective, multisite observational study enrolled patients from February 28, 2007, through December 30, 2011. Consecutive patients aged 19 years or younger who were approved to undergo WLS (n = 277) were offered enrollment into the study at 5 academic referral centers in the United States; 13 declined participation and 22 did not undergo surgery after enrollment, thus the final analysis cohort consisted of 242 individuals. There were no withdrawals. This analysis examined preoperative anthropometrics, comorbid conditions, and major and minor complications occurring within 30 days of operation. All data were collected in a standardized fashion. Reoperations and hospital readmissions were adjudicated by independent reviewers to assess relatedness to the WLS procedure. The mean (SD) age of participants was 17.1 (1.6) years and the median body mass index (calculated as weight in kilograms divided by height in meters squared) was 50.5. Fifty-one percent demonstrated 4 or more major comorbid conditions. Laparoscopic Roux-en-Y gastric bypass, vertical sleeve gastrectomy, and adjustable gastric banding were performed in 66%, 28%, and 6% of patients, respectively. There were no deaths during the initial hospitalization or within 30 days of operation; major complications (eg, reoperation) were seen in 19 patients (8%). Minor complications (eg, readmission for dehydration) were noted in 36 patients (15%). All reoperations and 85% of readmissions were related to WLS. In this series, adolescents with severe obesity presented with abundant comorbid conditions. We observed

The purpose of this study is to determine whether episode Target Prices in the Bundled Payment for Care Improvement (BPCI) initiative sufficiently match the complexities and expenses expected for patients undergoing hip arthroplasty for femoral neck fracture (FNF) as compared to hip degenerative joint disease (DJD). Claims data under BPCI Model 2 were collected for patients undergoing hip arthroplasty at a single institution over a 2-year period. Payments from the index hospitalization to 90 days postoperatively were aggregated by Medicare Severity Diagnosis-Related Group (469 or 470), indication (DJD vs FNF), and categorized as index procedure, postacute services, and related hospital readmissions. Actual episode costs and Target Prices were compared in both the FNF and DJD cohorts undergoing hip arthroplasty to gauge the cost discrepancy in each group. A total of 183 patients were analyzed (31 with FNFs, 152 with DJD). In total, the FNF cohort incurred a $415,950 loss under the current episode Target Prices, whereas the DJD cohort incurred a $172,448 gain. Episode Target Prices were significantly higher than actual episode prices for the DJD cohort ($32,573 vs $24,776, P expenses incurred by FNF patients undergoing hip arthroplasty. Better risk-adjusting Target Prices for this fragile population should be considered to avoid disincentives and delays in care. Copyright © 2018 Elsevier Inc. All rights reserved.

A common clinical dilemma regarding treatment of patients with a mechanical valve is the need for concomitant antiplatelet therapy for a variety of reasons, referred to as triple therapy. Triple therapy is when a patient is prescribed aspirin, a P2Y12 antagonist, and an oral anticoagulant. Based on the totality of the available evidence, best practice in 2017 for patients with mechanical valves undergoing percutaneous coronary intervention (PCI) is unclear. Furthermore, the optimal duration of dual antiplatelet therapy after PCI is evolving. With better valve designs that are less thrombogenic, the thromboembolic risks can be reduced at a lower international normalized ratio target, thus decreasing the bleeding risk. This review will offer an in-depth survey of current guidelines, current evidence, suggested approach for PCI in this cohort, and future studies regarding mechanical valve patients undergoing PCI.

Holding back, or withholding discussion of disease-related thoughts and emotions, is associated with negative outcomes including lower quality of life, diminished well-being, and relational distress. For patients undergoing hematopoietic stem cell transplantation (HSCT), the degree to which one holds back from discussing illness-related concerns may be an important determinant of social well-being and health; however, this has not been systematically assessed in this population. The purpose of the present study was to assess the moderating effects of holding back discussion of disease-related concerns on the relationship between health-related symptoms and social well-being in adult patients undergoing HSCT. Seventy autologous (n = 55) and allogeneic (n = 15) HSCT patients completed measures of holding back, social well-being, and health symptoms (i.e., pain, fatigue, sleep problems, cognitive problems) both before and after transplantation (i.e., three months after transplantation and six months after transplantation). In patients with average to high levels of holding back, health symptoms were significantly related to lower levels of social well-being; however, for patients with low levels of holding back, the relationship between health symptoms and social well-being was not significant. The results of the present study suggest that the level of holding back may be important in understanding how health-related symptoms relate to social well-being in patients undergoing HSCT. These findings underscore the importance of addressing how patients undergoing HSCT communicate about their disease with others as this may be related to their adjustment to illness and treatment.

Full Text Available Background: Quality of life (QOL of children with cancer reduces right from the diagnosis of disease and the start of treatment. Computer games in medicine are utilized to interact with patients and to improve their health-related behaviors. This study aimed to investigate the effect of an interactive computer game on the QOL of children undergoing chemotherapy. Materials and Methods: In this clinical trial, 64 children with cancer aged between 8 and12 years were selected through convenience sampling and randomly assigned to experimental or control group. The experimental group played a computer game for 3 hours a week for 4 consecutive weeks and the control group only received routine care. The data collection tool was the Pediatric Quality of Life Inventory (PedsQL 3.0 Cancer Module Child self-report designed for children aged between 8 to 12 years. Data were analyzed using descriptive and inferential statistics in SPSS software. Results: Before intervention, there was no significant difference between the two groups in terms of mean total QOL score (p = 0.87. However, immediately after the intervention (p = 0.02 and 1 month after the intervention (p < 0.001, the overall mean QOL score was significantly higher in the intervention group than the control group. Conclusions: Based on the findings, computer games seem to be effective as a tool in influencing health-related behavior and improving the QOL of children undergoing chemotherapy. Therefore, according to the findings of this study, computer games can be used to improve the QOL of children undergoing chemotherapy.

Distraction is often used in conjunction with analgesics to minimize pain in pediatric burn patients during treatment procedures. Computer tablets provide many options for distraction items in one tool and are often used during medical procedures. Few studies have examined the effectiveness of tablet distraction in improving the care of pediatric burn patients. This study examines the effectiveness of tablet distraction provided by a child life specialist to minimize pain and anxiety in pediatric burn patients undergoing hydrotherapy. Thirty pediatric patients (4-12) undergoing hydrotherapy for the treatment of burns participated in this randomized clinical trial. The tablet distraction group received tablet distraction provided by a child life specialist while those in the control group received standard care. Pain was assessed through self-reports and observation reports. Anxiety was assessed through behavioral observations. Length of procedure was also recorded. Nurses reported significantly less pain for the tablet distraction group compared to the control group. There was no significant difference between groups on self-reported pain. The tablet distraction group displayed significantly less anxiety during the procedure compared to the control group. Also, the tablet distraction group returned to baseline after the procedure while those in the control group displayed higher anxiety post-procedure. There was no difference in the length of the procedure between groups. These findings suggest tablet distraction provided by a child life specialist may be an effective method for improving pain and anxiety in children undergoing hydrotherapy treatment for burns.

Chemotherapy for breast cancer induces alopecia, representing a major source of patient distress. This study assesses whether a scalp-cooling device is effective in reducing chemotherapy-induced alopecia, and assesses adverse treatment effects. A prospective observational study including women with breast cancer undergoing chemotherapy and scalp cooling using a Paxman device. The primary efficacy end points were: successful hair preservation (no hair loss; <30% hair loss not requiring a wig; or <50% hair loss not requiring a wig) at the completion of chemotherapy. Secondary end points included adverse effects such as headache, pain, nausea or dizziness. The study enrolled 131 participants. Mean patient age was 49.8 years; 74% received anthracycline/taxane-based chemotherapy and 26% received taxane-monotherapy based chemotherapy. Hair preservation was successful in 102 women who underwent scalp cooling (71.0%; 95% CI = 63-79%). Only adverse events related to device use were collected, representing 7% (95% CI = 3-11%) of cases. Scalp cooling is effective in preventing hair loss among breast cancer patients undergoing standard chemotherapy treatment, and has minimal adverse effects. Copyright © 2018.

Approximately 300 children ages 0 to 18 are diagnosed with cancer in Sweden every year, and 80 to 90 of them undergo radiotherapy treatment. The aim was to describe children’s experiences of preparing for and undergoing radiotherapy, and furthermore to describe children’s suggestions for improvement. Thirteen children between the ages of 5 and 15 with various cancer diagnoses were interviewed. Data was analyzed using qualitative content analysis. The findings revealed five categories: positive and negative experiences with hospital stays and practical arrangements; age-appropriate information, communication, and guidance to various degrees; struggle with emotions; use of distraction and other suitable coping strategies; and children’s suggestions for improvement during radiotherapy. An overarching theme emerged: “It is tough and tiring but it works”. Some key areas were: explanatory visits, the need for information and communication, being afraid, discomfort and suffering, the need for media distraction, dealing with emotions, and the need for support. A systematic, family-centered preparation program could possible help families prepare and individualized distraction during radiotherapy could contribute to reducing distress. Further studies with interventions could clarify successful programs. PMID:27055258

To determine the prevalence of coronary artery disease in patients undergoing valve surgery at a tertiary care cardiac centre. The medical records of 144 consecutive patients who underwent mitral, aortic or dual (mitral and aortic) valve replacement surgery at the Tabba Heart Institute between January 2006 to December 2008 were retrospectively reviewed. All patients underwent coronary angiogram. Significant coronary artery disease (CAD) is defined as coronary stenosis of > 50%. There were 74 (51.4%) males and 70 (48.6%) females in the study. The mean age was 51.64 +- 11 years. Of all, 73 (50.7%) underwent mitral valve replacement, 47 (32.6%) had aortic and 24 (16.7%) had dual valve replacement. Out of 144 patients, 99 (68.8%) had 50% stenosis. In patients who had undergone mitral valve replacement (MVR), significant coronary disease was found in 32.9%, whereas in patients who had undergone aortic valve replacement (AVR) and dual valve replacement (DVR) the prevalence of coronary disease was 31.9% and 25% respectively. Our results suggest that the overall prevalence of coronary artery disease in patients undergoing valve surgery in our population is comparable with prevalence reported in international data.

The aim of this study was to describe the imaging appearance of patients undergoing active surveillance for ductal carcinoma in situ (DCIS). We retrospectively identified 29 patients undergoing active surveillance for DCIS from 2009 to 2014. Twenty-two patients (group 1) refused surgery or were not surgical candidates. Seven patients (group 2) enrolled in a trial of letrozole and deferred surgical excision for 6-12 months. Pathology and imaging results at the initial biopsy and follow-up were recorded. In group 1, the median follow-up was 2.7 years (range: 0.6-13.9 years). Fifteen patients (68%) remained stable. Seven patients (32%) underwent additional biopsies with invasive ductal carcinoma diagnosed in two patients after 3.9 and 3.6 years who developed increasing calcifications and new masses. In group 2, one patient (14%) was upstaged to microinvasive ductal carcinoma at surgery. Among the patients in both groups with calcifications (n = 26), there was no progression to invasive disease among those with stable (50%, 13/26) or decreased (19%, 5/26) calcifications. Among a DCIS active surveillance cohort, invasive disease progression presented as increasing calcifications and a new mass following more than 3.5 years of stable imaging. In contrast, there was no progression to invasive disease among cases of DCIS with stable or decreasing calcifications. Close imaging is a key follow-up component in active surveillance.

Cardiac complications are not uncommon in patients undergoing non-cardiac surgery, especially in patients with coronary artery disease (CAD) or at high risk of CAD. Perioperative cardiac complications can lead to mortality and morbidity, as well as higher costs for patient care. Nitrates, which are among the most commonly used cardiovascular drugs, perform the function of decreasing cardiac preload while improving cardiac blood perfusion. Sometimes, nitrates are administered to patients undergoing non-cardiac surgery to reduce the incidence of cardiac complications, especially for patients with CAD. However, their effects on patients' relevant outcomes remain controversial. • To assess effects of nitrates as compared with other interventions or placebo in reducing cardiac risk (such as death caused by cardiac factors, angina pectoris, acute myocardial infarction, acute heart failure and cardiac arrhythmia) in patients undergoing non-cardiac surgery.• To identify the influence of different routes and dosages of nitrates on patient outcomes. We searched the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, EMBASE and the Chinese BioMedical Database until June 2014. We also searched relevant conference abstracts of important anaesthesiology or cardiology scientific meetings, the database of ongoing trials and Google Scholar.We reran the search in January 2016. We added three potential new studies of interest to the list of 'Studies awaiting classification' and will incorporate them into our formal review findings for the review update. We included randomized controlled trials (RCTs) comparing nitrates versus no treatment, placebo or other pharmacological interventions in participants (15 years of age and older) undergoing non-cardiac surgery under any type of anaesthesia. We used standard methodological procedures as expected by Cochrane. Two review authors selected trials, extracted data from included studies and assessed risk of bias. We

We report a case of absolute vitamin K deficiency (VKD) diagnosed by measuring serum VK levels in an elderly woman undergoing warfarin therapy. A 78-year-old woman was admitted to our hospital because of dyspnea and sore throat diagnosed as pharyngitis 1 week before admission. On admission, the sore throat had exacerbated and dyspnea developed. She had history of atrial fibrillation, for which warfarin 1.5 mg/d was started approximately 10 years prior and her international normalized ratio (INR) had been maintained at an acceptable therapeutic level. Blood results revealed unmeasurable INR and abnormally prolonged activated partial thromboplastin time (APTT). She was diagnosed with adenoiditis and warfarin-related coagulopathy and administered intravenous VK (20 mg) and fresh frozen plasma (FFP; 4 U), which improved INR and APTT. Since the coagulopathy responded to intravenous VK administration, the patient was clinically diagnosed with warfarin-related relative VKD. Approximately 1 month later, she returned with complaints of sore throat. Blood results indicated abnormal INR (7.22) and APTT (N80.0 s). She was diagnosed with recurrent adenoiditis and VK deficient coagulopathy. The patient’s serum VK levels were low (VK1 level, 0.13 ng/mL; VK2 levels, 0.85 ng/mL). Initial treatment of VK (20 mg) and FFP followed by intravenous VK (20 mg/d) for 6 days, her symptoms dissipated. Warfarin was suspected to have caused absolute VKD. Severe coagulopathy in patients undergoing warfarin therapy is primarily caused by, relative VKD. However, the possibility of warfarin-related absolute VKD should be suspected when INRis not sufficiently improved by intravenous VK administration.

To evaluate the number, localisation and importance of non-traumatic incidental findings (IFs) in patients with suspected or obvious multiple trauma undergoing whole-body CT (WBCT) in a level-1 trauma centre. Between January 2009 and December 2013, a total of 2440 patients with trauma undergoing WBCT at admission to a level-1 trauma centre of a university hospital were retrospectively analysed, through imaging IFs unrelated to trauma with the radiological reports. All IFs were grouped into four categories according to their clinical relevance. Category 1: urgent treatment or further clarification needed; category 2: further examination and follow-up within 3-6 months required; category 3: findings with no immediate consequences for the treatment of the patient but of potential relevance in the future; category 4: harmless findings. Altogether, 5440 IFs in 2440 patients (1735 male, 705 female; mean age 45.1 years) were documented. In 204 patients (8.4%) urgent category 1 findings were reported, 766 patients (31.4%) had category 2 findings, 1236 patients (50.7%) had category 3 findings and 1173 patients (48.1%) had category 4 findings. Most IFs were detected in the abdomen/pelvis (42.5%). 602 (24.7%) of the patients had no IFs. WBCT scans of unrelated trauma patients demonstrate a high rate of IF. A substantial percentage (8.4%) of patients had urgent category 1IFs and a high percentage (31.4%) had category 2 IFs requiring a follow-up. This high number of patients with polytrauma undergoing WBCT, having IFs of high relevance, poses a major challenge for the level-1 trauma centre in the acute and postacute management of these patients. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

The Impact of Abdominal Fat Levels on All-Cause Mortality Risk in Patients Undergoing Hemodialysis

Directory of Open Access Journals (Sweden)

Takahiro Yajima

2018-04-01

Full Text Available Although an increased body mass index is associated with lower mortality in patients undergoing hemodialysis (HD, known as the “obesity paradox,” the relationship of abdominal fat levels with all-cause mortality has rarely been studied. We investigated the impact of computed-tomography-measured abdominal fat levels (visceral fat area (VFA and subcutaneous fat area (SFA on all-cause mortality in this population. A total of 201 patients undergoing HD were enrolled and cross-classified by VFA and SFA levels according to each cutoff point, VFA of 78.7 cm2 and SFA of 93.2 cm2, based on the receiver operator characteristic (ROC curve as following; group 1 (G1: lower VFA and lower SFA, G2: higher VFA and lower SFA, G3: lower VFA and higher SFA, G4: higher VFA and higher SFA. During a median follow-up of 4.3 years, 67 patients died. Kaplan–Meier analysis revealed 10-year survival rates of 29.0%, 50.0%, 62.6%, and 72.4% in G1, G2, G3, and G4 (p < 0.0001, respectively. The adjusted hazard ratio was 0.30 (95% confidence interval [CI] 0.05–1.09, p = 0.070 for G2 vs. G1, 0.37 (95% CI 0.18–0.76, p = 0.0065 for G3 vs. G1, and 0.21 (95% CI 0.07–0.62, p = 0.0035 for G4 vs. G1, respectively. In conclusion, combined SFA and VFA levels were negatively associated with risks for all-cause mortality in patients undergoing HD. These results are a manifestation of the “obesity paradox.”

The aim of this research was to determine whether presence of atrial fibrillation (AF) provides incremental prognostic information relative to myocardial perfusion single-photon emission computed tomography (MPS) with respect to risk of cardiac death (CD). The prognostic significance of AF in patients undergoing MPS is not known. A total of 16,048 consecutive patients undergoing MPS were followed-up for a mean of 2.21 +/- 1.15 years for the development of CD. Of those, 384 patients (2.4%) had AF. Cox proportional hazards method was used to compare clinical and perfusion data for the prediction of CD in patients with and without AF. Atrial fibrillation was a significant predictor of CD in patients with normal (1.6% per year vs. 0.4% per year in non-AF patients), mildly abnormal (6.3% per year vs. 1.2% per year), and severely abnormal MPS (6.4% per year vs. 3.7% per year) (p < 0.001 for all). By multivariable analysis, AF patients had worse survival (p = 0.001) even after adjustment for the variables most predictive of CD: age, diabetes, shortness of breath, use of vasodilator stress, rest heart rate, and the nuclear variables. In the 4,239 patients with left ventricular ejection fraction evaluated by gated MPS, AF demonstrated incremental prognostic value not only over clinical and nuclear variables, but also over left ventricular ejection in predicting CD (p = 0.014). The presence of AF independently increases the risk of cardiac events over perfusion and function variables in patients undergoing MPS. Patients with AF have a high risk of CD, even when MPS is only mildly abnormal. Whether patients with AF and mildly abnormal MPS constitute a group more deserving of early referral to cardiac catheterization is a question warranting further study.

Urinary retention is a common complication of pelvic surgery, leading to urinary tract infection and prolonged hospital stays. Tamsulosin is an alpha blocker that works by relaxing bladder neck muscles. It is used to treat benign prostatic hypertrophy and retention. We aim to investigate the potential benefits of preemptive tamsulosin use on rates of urinary retention in men undergoing pelvic surgery. This is a retrospective review of an institutional colorectal database. All men undergoing pelvic surgery between 2004 and 2013 were included. Patients given 0.4 mg of tamsulosin 3 days prior and after surgery at discretion of surgeon starting in 2007 were compared with patients receiving expectant postoperative management. One hundred eighty-five patients were included in the study (study group: N = 30; control group: N = 155). Study group patients were older (56.8 vs. 50.1 years). Overall urinary retention rate was 22% with significantly lower rates in the study group compared with control (6.7 vs. 25%; p = 0.029). Study group had higher rates of minimally invasive surgery (61 vs. 29.7%); however, this did not impact urinary retention rate (20.6 vs. 22.7% for minimally invasive surgery vs. open surgery; p = 0.85). Independent predictors of urinary retention included lack of preemptive tamsulosin (odds ratio (OR), 7.67; 95% confidence interval (CI), 1.4-41.7) and cancer location in the distal third of the rectum (OR, 18.8; 95% CI, 2.1-172.8). Preemptive perioperative use of tamsulosin may significantly decrease the incidence of urinary retention in men undergoing pelvic surgery. This may play a role in avoidance of urinary retention, particularly in patients with distal rectal cancer.

Approximately 4000 U.S. children undergo tracheostomy yearly [1], and these surgeries often result in hospital re-admissions that have definite cost and caregiver burdens due to complications that are avoidable with proper training and support. To assess the impact of a Family-Centered Care Coordination (FCCC) program on the quality of care received by children undergoing tracheostomy and their caregivers. Caregivers of children undergoing tracheostomies from January 2012 to January 2013 and then a different set of caregivers of children undergoing tracheostomies from January 2015 to January 2016 completed both the Pediatric Tracheostomy Health Status Instrument (PTHSI) 1 month after discharge and the Medical Complications Associated with Pediatric Tracheostomy (MCAT) questionnaire 6 months after initial tracheostomy. To assess complication rates, these same sets of caregivers were asked to complete the MCAT and only those who provided complete medical data for all 6 months were included for comparative analysis. The PTHSI and MCAT were administered at Massachusetts Eye and Ear in a hospital setting. Ten caregivers of children undergoing tracheostomies completed the PTHSI before FCCC program implementation and12 caregivers then completed the PTHSI after FCCC implementation. For each of the 2 groups, 5 caregivers provided complete data on the MCAT questionnaires. FCCC is a collection of programs, policies, and tools designed to ensure safe transition home for children undergoing tracheostomies, reduce re-admission rates, and minimize "caregiver burden". The PTHSI is a validated caregiver quality of life instrument that was supplemented by the MCAT which records post-discharge medical issues following tracheostomy that relate specifically to the tracheotomy placement. The time to first follow-up appointment decreased from 6.4 weeks (SD = 1.52) to 6 days (SD = 0.18) with FCCC implementation. The total MCAT scores decreased from 15.2 (SD = 1.1) to 1.3 (SD = 1

In open heart surgery using cardiopulmonary bypass, perfusion of the lower extremities is markedly reduced which may induce critical ischaemia in patients with pre-existing peripheral artery disease. Whether these patients have an increased risk for amputation and should better undergo peripheral revascularization prior to surgery remains unclear. From 1 January 2009 to 31 December 2010, 785 consecutive patients undergoing open heart surgery were retrospectively included. In 443 of these patients, preoperative ankle brachial index (ABI) measurements were available. The cohort was divided into four groups: (i) ABI heart surgery showed more wound-healing disturbances, and higher long-term mortality compared with those with normal ABIs. However, no perioperative ischaemia requiring amputation occurred. Thus, reduced ABIs were not associated with increased peripheral risks in open heart surgery but ABI may be helpful in selecting the site for saphenectomy to potentially avoid delayed healing of related wounds in legs with severely impaired arterial perfusion. © The Author 2015.

Intervention of medical clowns (MC) during various medical procedures performed in children has been used to relieve anxiety and pain. Their role in allergy skin testing has never been evaluated. To evaluate whether MC can diminish pain and anxiety perceived by children undergoing allergy skin prick tests (SPT). In a prospective, randomized, controlled, and blinded study, children undergoing SPT were or were not accompanied by MC. All parents and children ≥8 years completed the State-Trait Anxiety Inventory (STAI) before and after SPT. Videotapes recorded during the procedure were scored for anxiety (m-YPAS) for all children and for pain (FLACC) for children 2-7 years old by a psychologist who was unaware of the MC's presence. After SPT, children ≥8 years completed a visual analog score (VAS) for pain. Ninety-one children (mean age 8.2 years, M/F = 54/37) were recruited of whom 45 were accompanied by clowns. A significant reduction in state-STAI was found in the clowns group, in both parents and children, when compared with the regular group (26.9 ± 6.6 and 32.3 ± 10.0; P = 0.004, and 27.1 ± 4.2 and 34.3 ± 7.6; P = 0.002, respectively). Both m-YPAS and FLACC were reduced in the clowns group compared with the regular one. In the clowns group, m-YPAS positively correlated with both VAS and FLACC (P = 0.000 and 0.002, respectively). m-YPAS was positively correlated with FLACC in the regular group (P = 0.000). Medical clowns significantly decrease the level of anxiety perceived by both children undergoing allergy SPT and their parents, as well as the pain perceived by young children. © 2014 John Wiley & Sons A/S.

Society for Vascular Surgery practice guidelines for the medical treatment of intermittent claudication give a GRADE 1A recommendation for smoking cessation. Active smoking is therefore expected to be low in patients suffering from intermittent claudication selected for vascular surgical intervention. The aim of this study is to evaluate the prevalence of smoking in patients undergoing intervention for intermittent claudication at the national level and to determine the relationship between smoking status and intervention. The Vascular Quality Initiative (VQI) registries for infra-inguinal bypass, supra-inguinal bypass, and peripheral vascular intervention (PVI) were queried to identify patients who underwent invasive treatment for intermittent claudication. Patient factors, procedure type (bypass versus PVI), and level of disease (supra-inguinal versus infra-inguinal) were evaluated for associations with smoking status (active smoking or nonsmoking) by univariate and covariate analysis. Between 2010 and 2015, 101,055 procedures were entered in the 3 registries, with 40,269 (40%) performed for intermittent claudication. Complete data for analysis were present in 37,632 cases. At the time of intervention, 44% of patients were active smokers, with wide variation by regional quality group (16-53%). In covariate analysis, active smoking at treatment was associated with age smoking status. During follow-up, 36% of patients had quit smoking. Predictors of smoking cessation included age ≥70 years (RR 1.45), ABI ≥0.9 (RR 1.12), and bypass procedures (RR 1.22). At the time of treatment, 44% of patients undergoing intervention for intermittent claudication in the VQI were active smokers and there was a wide regional variation. Prevalence of active smoking was greater in the presence of younger age, fewer comorbidities, lower ABI, and supra-inguinal disease. Type of procedure performed, and in turn level of invasiveness required, did not appear to be influenced by smoking

Full Text Available Blood conservation is an important aspect of care provided to the patients undergoing cardiac operations with cardiopulmonary bypass (CPB. It is even more important in patients with anticipated prolonged CPB, redo cardiac surgery, patients having negative blood group and in patients undergoing emergency cardiac surgery. In prolonged CPB the blood is subjected to more destruction of important coagulation factors, in redo surgery the separation of adhesions leads to increased bleeding and difficulty in achieving the haemostasis and in patients with negative blood group and emergency operations, the availability of sufficient blood can be a problem. Harvesting the autologous platelet rich plasma (PRP can be a useful method of blood conservation in these patients. The above four categories of patients were prospectively studied, using either autologous whole blood donation or autologous platelet rich plasma (PRP harvest in the immediate pre-bypass period. Forty two patients were included in the study and randomly divided into two equal groups of 21 each, control group (Group I in which one unit of whole blood was withdrawn, and PRP group (Group II where autologous plateletpheresis was utilised. After reversal of heparin, autologous whole blood was transfused in the control group and autologous PRP was transfused in the PRP group. The chest tube drainage and the requirement of homologous blood and blood products were recorded. Average PRP harvest was 643.33 +/- 133.51 mL in PRP group and the mean whole blood donation was 333.75 +/- 79.58 mL in the control group. Demographic, preoperative and intra operative data showed no statistically significant differences between the two groups. The PRP group patients drained 26.44% less (p<0.001 and required 38.5% less homologous blood and blood products (p<0.05, in the postoperative period. Haemoglobin levels on day zero (day of operation and day three were statistically not different between the two groups. We

Full Text Available Abstract Background Prolonged, altered hematopoietic reconstitution is commonly observed in patients undergoing myeloablative conditioning and bone marrow and/or mobilized peripheral blood-derived stem cell transplantation. We studied the reconstitution of myeloid and lymphoid compartments after the transplantation of autologous CD34+ bone marrow cells following gamma irradiation in cynomolgus macaques. Results The bone marrow cells were first transduced ex vivo with a lentiviral vector encoding eGFP, with a mean efficiency of 72% ± 4%. The vector used was derived from the simian immunodeficiency lentivirus SIVmac251, VSV-g pseudotyped and encoded eGFP under the control of the phosphoglycerate kinase promoter. After myeloid differentiation, GFP was detected in colony-forming cells (37% ± 10%. A previous study showed that transduction rates did not differ significantly between colony-forming cells and immature cells capable of initiating long-term cultures, indicating that progenitor cells and highly immature hematopoietic cells were transduced with similar efficiency. Blood cells producingeGFP were detected as early as three days after transplantation, and eGFP-producing granulocyte and mononuclear cells persisted for more than one year in the periphery. Conclusion The transplantation of CD34+ bone marrow cells had beneficial effects for the ex vivo proliferation and differentiation of hematopoietic progenitors, favoring reconstitution of the T- and B-lymphocyte, thrombocyte and red blood cell compartments.

The intensive and prolonged immunosuppressive therapy required to prevent or treat graft-versus-host disease (GVHD) after allogeneic blood or marrow transplantation (alloBMT) puts patients at substantial risk for life-threatening infections, organ toxicity, and disease relapse. Posttransplantation cyclophosphamide (PTCy) can function as single-agent GVHD prophylaxis after myeloablative, HLA-matched related (MRD), or HLA-matched unrelated (MUD) donor T-cell-replete bone marrow allografting, obviating the need for additional prophylactic immunosuppression. However, patients who develop GVHD require supplemental treatment. We assessed the longitudinal requirement for immunosuppressive therapy in 339 patients treated with this transplantation platform: 247 receiving busulfan/cyclophosphamide (BuCy) conditioning (data collected retrospectively) and 92 receiving busulfan/fludarabine (BuFlu) conditioning (data collected prospectively). Approximately 50% of MRD patients and 30% of MUD patients never required immunosuppression beyond PTCy. In patients requiring further immunosuppression, typically only 1 to 2 agents were required, and the median durations of systemic pharmacologic immunosuppression for the BuCy MRD, BuFlu MRD, BuCy MUD, and BuFlu MUD groups all were 4.5 to 5 months. For these 4 groups, 1-year probabilities of being alive and off all systemic immunosuppression were 61%, 53%, 53%, and 51% and 3-year probabilities were 53%, 48%, 49%, and 56%, respectively. These data suggest that PTCy minimizes the global immunosuppressive burden experienced by patients undergoing HLA-matched alloBMT.

Is Antibiotic Prophylaxis Necessary in Patients Undergoing Ureterolithotripsy?

Ali Pasha Meysamie

2011-08-01

Full Text Available Transurethral Ureterolithotripsy (TUL is a frequently used procedure in urology departments. Many urologists perform TUL without antibiotic prophylaxis; however the use of chemoprophylaxis before TUL remains a controversial issue in urology. Thisstudy was carried out to assess the safety of omitting antibiotic prophylaxis prior to TUL. In a prospective randomized clinical trial from January 2005 to December 2007, 114 patients with ureteral stones were enrolled; Fifty seven had preoperative antibiotic prophylaxis administered before TUL and fifty seven patients underwent TUL without antibiotic prophylaxis. The rate of postoperative infectious complications (fever, positive blood culture, significant bactriuria, the length of hospital stay and overall stone free rate were compared between the two groups. There was no statistically significant difference between two groups in the operation time, length of hospital stay, postoperative bacteriuria, positive urine culture, postoperative fever and overall success rate of TUL. It appears that the incidence of infectious complications does not increase in patients undergoing TUL without antibiotic prophylaxis if they have negative pre-operative urine culture and antiseptic technique have been performed thorough the procedure.

This work discusses the production and management of liquid radioactive wastes as excretas from patients undergoing therapy procedures with {sup 131}I radiopharmaceuticals in Spain. The activity in the sewage has been estimated with and without waste radioactive decay tanks. Two common therapy procedures have been considered, the thyroid cancer (4.14 GBq administered per treatment), and the hyperthyroidism (414 MBq administered per treatment). The calculations were based on measurements of external exposure around the 244 hyperthyroidism patients and 23 thyroid cancer patients. The estimated direct activity discharged to the sewage for two thyroid carcinomas and three hyperthyroidisms was 14.57 GBq and 1.27 GBq, respectively, per week; the annual doses received by the most exposed individual (sewage worker) were 164 {mu}Sv and 13 {mu}Sv, respectively. General equations to calculate the activity as a function of the number of patient treated each week were also obtained.

Electrical impedance tomography (EIT) can determine ventilation and perfusion relationship. Most of the data obtained so far originates from experimental settings and in healthy subjects. The aim of this study was to demonstrate that EIT measures the perioperative changes in pulmonary blood flow after repair of a ventricular septum defect in children with haemodynamic relevant septal defects undergoing open heart surgery. In a 19 bed intensive care unit in a tertiary children's hospital ventilation and cardiac related impedance changes were measured using EIT before and after surgery in 18 spontaneously breathing patients. The EIT signals were either filtered for ventilation (ΔZV) or for cardiac (ΔZQ) related impedance changes. Impedance signals were then normalized (normΔZV, normΔZQ) for calculation of the global and regional impedance related ventilation perfusion relationship (normΔZV/normΔZQ). We observed a trend towards increased normΔZV in all lung regions, a significantly decreased normΔZQ in the global and anterior, but not the posterior lung region. The normΔZV/normΔZQ was significantly increased in the global and anterior lung region. Our study qualitatively validates our previously published modified EIT filtration technique in the clinical setting of young children with significant left-to-right shunt undergoing corrective open heart surgery, where perioperative assessment of the ventilation perfusion relation is of high clinical relevance.

Listening to music can be a noninvasive method for reducing the anxiety level without any adverse effects. The aim of this study was to explore whether music can reduce anxiety and to compare two different styles of music, informal classical music and light music, to ascertain the more effective style of music in reducing anxiety in patients undergoing colonoscopy without sedation. This study enrolled 138 patients who underwent colonoscopy without sedation during a general health examination from February 2009 to January 2015. The patients were randomly assigned to a group that did not listen to music, a group that listened to music by David Tolley, or a group that listened to music by Kevin Kern. The State-Trait Anxiety Inventory was used to evaluate the status of anxiety. A trend test for mild anxiety was performed on the patients in the three groups, and a significant trend was noted (p=0.017 for all patients; p=0.014 for analysis by sex). Multivariate analysis for mild anxiety on the patients in each group was also performed in this study, and music by Kevin Kern was found to have the lowest odds ratio (Odds ratio=0.34, p=0.045). Listening to music, especially music by Kevin Kern, reduced the level of anxiety in patients undergoing colonoscopy examination without sedation. Copyright © 2016. Published by Elsevier Taiwan LLC.

The purpose was to understand the processes Hispanic parents undergo in managing postoperative care of children after routine surgical procedures. Sixty parents of children undergoing outpatient surgery were interviewed. Data were analyzed using grounded theory methodology. Parents experienced five subprocesses that comprised the overall process of caring for a child after routine surgery: (a) becoming informed; (b) preparing; (c) seeking reassurance; (d) communicating with one's child; and (e) making pain management decisions. Addressing cultural factors related to pain management in underserved families may instill greater confidence in managing pain. © 2015, Wiley Periodicals, Inc.

Patients who undergo prolonged surgical procedures are at risk of developing pressure ulcers. Recent systematic reviews suggest that pressure redistribution overlays on operating tables significantly decrease the associated risk. Little is known about the cost effectiveness of using these overlays in a prevention program for surgical patients. Using a Markov cohort model, we evaluated the cost effectiveness of an intraoperative prevention strategy with operating table overlays made of dry, viscoelastic polymer from the perspective of a health care payer over a 1-year period. We simulated patients undergoing scheduled surgical procedures lasting ≥90 min in the supine or lithotomy position. Compared with the current practice of using standard mattresses on operating tables, the intraoperative prevention strategy decreased the estimated intraoperative incidence of pressure ulcers by 0.51%, corresponding to a number-needed-to-treat of 196 patients. The average cost of using the operating table overlay was $1.66 per patient. Compared with current practice, this intraoperative prevention strategy would increase slightly the quality-adjusted life days of patients and by decreasing the incidence of pressure ulcers, this strategy would decrease both hospital and home care costs for treating fewer pressure ulcers originated intraoperatively. The cost savings was $46 per patient, which ranged from $13 to $116 by different surgical populations. Intraoperative prevention was 99% likely to be more cost effective than the current practice. In patients who undergo scheduled surgical procedures lasting ≥90 min, this intraoperative prevention strategy could improve patients' health and save hospital costs. The clinical and economic evidence support the implementation of this prevention strategy in settings where it has yet to become current practice. Copyright © 2011 Mosby, Inc. All rights reserved.

Few studies have investigated the efficacy and safety of the nerve-sparing approach via minimally invasive surgery for the treatment of cervical cancer. We aimed to review the current evidence comparing nerve-sparing minimally invasive radical hysterectomy (NS-MRH) with conventional minimally invasive radical hysterectomy (MRH). This systematic review was registered in the International Prospective Register of Systematic Reviews (CRD#57655). Overall, 675 patients were included: 350 (51.9%) and 325 (48.1%) patients undergoing MRH and NS-MRH, respectively. MRH was associated with a shorter operative time in comparison with NS-MRH (mean difference = 32.57 minutes; 95% CI, 22.87-42.48). The estimated blood loss (mean difference = 97.14 mL, 20.01-214.29) and transfusion rate (odds ratio [OR] = 0.67; 95% confidence interval [CI], 0.15-3.01) did not differ statistically between the 2 groups. The risk of developing intraoperative (OR = 0.43; 95% CI, 0.08-2.23) and severe postoperative (OR = 0.63; 95% CI, 0.17-2.39) complications was similar between NS-MRH and MRH. Patients undergoing NS-MRH experienced lower voiding (OR = 0.39; 95% CI, 0.19-0.81) dysfunction rates than patients undergoing MRH. Moreover, a trend toward lower sexual (OR = 0.25; 95% CI, 0.06-1.07) and rectal (OR = 0.12; 95% CI, 0.01-1.02) issues was observed for patients having NS-MRH compared with patients undergoing MRH. Survival outcomes are not influenced by the type of surgical approach (recurrence [OR = 1.27; 95% CI, 0.49-3.28] and death [OR = 1.01; 95% CI, 0.36-2.83]) rates. The pooled data suggested that NS-MRH is equivalent to MRH for the treatment of cervical cancer and may be superior in reducing pelvic floor dysfunction rates. However, because of the low level of evidence of the included studies, further randomized trials are warranted. Copyright © 2017 American Association of Gynecologic Laparoscopists.

Bivalirudin use as a procedural anticoagulant in patients undergoing percutaneous coronary intervention (PCI) is associated with a lower incidence of thrombocytopaenia compared to other antithrombotic agents. We aimed to evaluate the prognostic impact of baseline thrombocytopaenia and early changes in platelet counts among patients undergoing PCI with exclusive use of bivalirudin. We evaluated 7,505 patients who underwent PCI over a period of eight years. Patients who received unfractionated heparin and glycoprotein IIb/IIIa receptor inhibitors were specifically excluded. Eight hundred and fifty-eight (11.4%) patients had baseline thrombocytopaenia and 451 (6.0%) developed acquired thrombocytopaenia. After adjustment for potential covariates, moderate to severe acquired thrombocytopaenia was the strongest independent predictor (HR 4.34, 95% CI: 2.13-8.84; pevents, which included major adverse cardiac events and major bleeding complications. Age, male gender, baseline platelet count and intra-aortic balloon pump (IABP) insertion were independent predictors of in-hospital acquired thrombocytopaenia. After a mean follow-up of 2.6±1.7 years, moderate to severe baseline thrombocytopaenia (HR 2.42, 95% CI: 1.79-3.29; p67 k) were significant predictors of mortality. In patients undergoing PCI with bivalirudin, moderate to severe baseline and acquired thrombocytopaenia along with severe changes in platelet count are associated with higher long-term mortality.

Diabetes mellitus (DM) is risk factor for complications after orthopedic surgery. We tested the hypothesis that anesthesia preoperative clinic (APC) referral for elevated glycosylated hemoglobin (HbA1c) reduces complication rate after total joint arthroplasty (TJA). Patients (n = 203) with and without DM were chosen from 1,237 patients undergoing TJA during 2006 - 12. Patients evaluated in the APC had surgery in 2006 - 8 regardless of HbA1c (uncontrolled). Those evaluated between in subsequent two-year intervals were referred to primary care for HbA1c ≥ 10% and ≥ 8%, respectively, to improve DM control before surgery. Complications and mortality were quantified postoperatively and at three, six, and twelve months. Length of stay (LOS) and patients requiring a prolonged LOS (> 5 days) were recorded. Patients (197 men, 6 women) underwent 71, 131, and 1 total hip, knee, and shoulder replacements, respectively. Patients undergoing TJA with uncontrolled HbA1c and those with HbA1c patients without DM. An increase in complication rate was observed in DM patients with uncontrolled HbA1c versus patients without DM (P patients with preoperative HbA1c that was uncontrolled or ≥ 10% required prolonged LOS versus those without DM (P diabetics undergoing TJA.

The aim of this study was to evaluate the prognostic value of soluble CD40 ligand (sCD40L) in patients with ST-segment elevation myocardial infarction (STEMI) undergoing a primary percutaneous coronary intervention (PCI). The prognostic value of sCD40L has been documented in patients with acute coronary syndrome; however, its value in acute STEMI remains unclear. We prospectively enrolled 499 consecutive STEMI patients (397 men, 102 women) undergoing primary PCI. The study population was divided into tertiles on the basis of admission sCD40L values. The high sCD40L group (n=168) included patients with a value in the third tertile (≥0.947 mg/l) and the low sCD40L group (n=331) included patients with a value in the lower two tertiles (0.947 mg/l) is a powerful independent predictor of 1-year all-cause mortality (odds ratio: 3.68; 95% confidence interval: 1.54-8.77; P=0.003). The results of this study suggest that a high sCD40L level at admission is associated with increased in-hospital and 1-year all-cause mortality rates in patients with STEMI undergoing primary PCI.

Although chronic obstructive pulmonary disease (COPD) has been implicated as a risk factor for abdominal aortic aneurysm (AAA) rupture, its effect on surgical repair is less defined. Consequently, variation in practice persists regarding patient selection and surgical management. The purpose of this study was to analyze the effect of COPD on patients undergoing AAA repair. We reviewed a prospective regional registry of 3455 patients undergoing elective open AAA repair (OAR) and endovascular AAA repair (EVAR) from 23 centers in the Vascular Study Group of New England from 2003 to 2011. COPD was categorized as none, medical (medically treated but not oxygen [O2]-dependent), and O2-dependent. End points included in-hospital death, pulmonary complications, major postoperative adverse events (MAEs), extubation in the operating room, and 5-year survival. Survival was determined using life-table analysis based on the Social Security Death Index. Predictors of in-hospital and long-term mortality were determined by multivariate logistic regression and Cox proportional hazards analysis. During the study interval, 2043 patients underwent EVAR and 1412 patients underwent OAR with a nearly equal prevalence of COPD (35% EVAR vs 36% OAR). O2-dependent COPD (4%) was associated with significantly increased in-hospital mortality, pulmonary complications, and MAE and was also associated with significantly decreased extubation in the operating room among patients undergoing both EVAR and OAR. Five-year survival was significantly diminished among all patients undergoing AAA repair with COPD (none, 78%; medical, 72%; O2-dependent, 42%; P < .001). By multivariate analysis, O2-dependent COPD was independently associated with in-hospital mortality (odds ratio 2.02, 95% confidence interval, 1.0-4.0; P = .04) and diminished 5-year survival (hazard ratio, 3.02; 95% confidence interval, 2.2-4.1; P < .001). Patients with O2-dependent COPD undergoing AAA repair suffer increased pulmonary

Postoperative vomiting (POV) is one of the most frequent complications of tonsillectomy in children. The aim of this study was to evaluate the antiemetic effect of super-hydration with lactated Ringer's solution in children undergoing elective otorhinolaryngological surgery. One hundred ASA I-II children, aged 1-12 yr, undergoing elective tonsillectomy, with or without adenoidectomy, under general anaesthesia were studied. Induction and maintenance of anaesthesia were standardized with fentanyl, mivacurium, and sevoflurane in N(2)O/O(2). Subjects were assigned to one of the two groups: 10 ml kg(-1) h(-1) lactated Ringer's solution or 30 ml kg(-1) h(-1) lactated Ringer's solution. A multivariable logistic regression was used for assessing the effects of super-hydration on POV (defined as the presence of retching, vomiting, or both). A value of P<0.05 was considered statistically significant. During the first 24 h postoperative, the incidence of POV decreased from 82% to 62% (relative reduction of 24%, P=0.026). In the adjusted logistic regression model, subjects in the 10 ml kg(-1) h(-1) group had an odds ratio of POV that was 2.92 (95% confidence interval: 1.14, 7.51) for POV compared with subjects in the 30 ml kg(-1) h(-1) group. Intraoperative administration of 30 ml kg(-1) h(-1) lactated Ringer's solution significantly reduced the incidence of POV during the first 24 h postoperative. Our results support the use of super-hydration during tonsillectomy, as an alternative way to decrease the risk of POV in children.

Full Text Available ABSTRACT Objective: To investigate the relationship between preoperative vitamin D and albumin levels and postoperative quality of life in patients undergoing spinal surgery. Methods: Patients undergoing thoracic and lumbar spine surgery were evaluated in this prospective study. Their vitamin D and albumin levels were assessed before surgery and quality of life was measured by two questionnaires, Oswestry Disability Index (ODI and Scoliosis Research Society - 22 (SRS-22, one year after the procedure. Data on infection occurrence and healing time were collected. Preoperative nutritional values and patients’ quality of life were analyzed using the chi-square test and ANOVA for albumin and vitamin D, respectively. The relationship among nutritional status, healing time, and the occurrence of infection was evaluated by the Pearson correlation coefficient. Results: Forty-six patients were included and their mean nutritional values were 19.1 (6.6 ng/mL for vitamin D and 3.9 (0.6 g/dL for albumin [mean (standard deviation]. No association was found between vitamin D and quality of life of patients measured by ODI (p=0.534 and SRS-22 (p=0.739 questionnaires. There was also no association between albumin levels and quality of life measured by ODI (p=0.259 and SRS-22 (p=0.076 questionnaires. No correlation was found between the healing time or occurrence of infection and nutritional values. Conclusions: There was no association between vitamin D and albumin levels and the surgical result, according to the patient’s perception, besides the occurrence of complications with the surgical wound.

Full Text Available ABSTRACT OBJECTIVE: To identify the characteristics of patients with spinal cord injury (SCI undergoing surgery. METHODS: Previously, 321 patients with SCI were selected. Clinical and socio-demographic variables were collected. RESULTS: A total of 211 patients were submitted to surgery. Fall and injuries in the upper cervical and lumbosacral regions were associated with conservative treatment. Patients with lesions in the lower cervical spine, worse neurological status, and unstable injuries were associated with surgery. Individuals undergoing surgery were associated with complications after treatment. The authors assessed whether age influenced the characteristics of patients submitted to surgery. Subjects with <60 years of age were associated with motorcycle accidents and the morphologies of injury were fracture-dislocation. Elderly individuals were associated to fall, SCI in the lower cervical spine and the morphology of injury was listhesis. Subsequently, the authors analyzed the gender characteristics in these patients. Women who suffered car accidents were associated to surgery. Women were associated with paraparesis and the morphologic diagnosis was fracture-explosion, especially in the thoracolumbar transition and lumbosacral regions. Men who presented traumatic brain injury and thoracic trauma were related to surgery. These individuals had a worse neurological status and were associated to complications. Men and the cervical region were most affected, thereby, these subjects were analyzed separately (n= 92. The presence of complications increased the length of hospital stay. The simultaneous presence of morphological diagnosis, worst neurological status, tetraplegia, sensory, and motor alterations were associated with complications. Pneumonia and chest trauma were associated with mortality. CONCLUSION: These factors enable investments in prevention, rehabilitation, and treatment.

Peri-operative management of infants with trisomy 18 syndrome is challenging due to various congenital cardiac and facial anomalies. We report the anaesthetic management of a 13-day-old neonate with 1 540 g body weight, undergoing closure of patent ductus arteriosus and pulmonary artery banding. Anaesthesia was induced with sevoflurane, fentanyl and rocuronium. Despite dysmorphic facial features, ventilation and endotracheal intubation were achieved uneventfully. Anaesthesia was maintained with sevoflurane and fentanyl and was uneventful. The patient was transferred to the neonatal ICU intubated and with ventilatory support. The baby was extubated on the second day postoperatively. Our knowledge of the proper anaesthetic technique for children undergoing palliative or corrective surgery is limited. Further case reports will increase our experience in peri-operative management of children with trisomy 18.

Background Symptoms of heart failure with preserved left ventricular systolic function are common among patients undergoing peritoneal dialysis (PD). Epicardial fat (EpF) is an ectopic fat depot with possible paracrine or mechanical effects on myocardial function. The aim of our current study is to assess the association between EpF and Left ventricular diastolic dysfunction (LVDD) in patients undergoing PD and to clarify the relationships among EpF, inflammation, and LVDD in this population....

It has long been recognized that differences exist between men and women in the impact of risc factors, symptoms, development and outcome of special diseases like the cardiovascular disease. Gender determines the cardiac baseline parameters like the number of cardiac myocyte, size and demand and may suggest differences in myofilament function among genders, which might be pronounced under pathological conditions. Does gender impact and maybe impair the contractile apparatus? Are the differences more prominent when other factors like weight, age, ejection fraction are added?Therefore we performed a study on 36 patients (21 male, 15 female) undergoing aortic valve replacement (AVR) or aortocoronary bypass operation (CABG) to examine the influence of gender, ejection fraction, surgical procedure and body mass index (BMI) on cardiac force development. Tissue was obtained from the right auricle and was stored in a special solution to prevent any stretching of the fibers. We used the skinned muscle fiber model and single muscle stripes, which were mounted on the "muscle machine" and exposed to a gradual increase of calcium concentration calculated by an attached computer program. 1.) In general female fibers show more force than male fibers: 3.9 mN vs. 2.0 mN (p = 0.03) 2.) Female fibers undergoing AVR achieved more force than those undergoing CABG operation: 5.7 mN vs. 2.8 mN (p = 0.02) as well as male fibers with AVR showed more force values compared to those undergoing CABG: 2.0 mN vs. 0.5 mN (p = 0.01). 3.) Male and female fibers of patients with EF > 55% developed significantly more force than from those with less ejection fraction than 30%: p = 0.002 for the male fibers (1.6 vs. 2.8 mN) and p = 0.04 for the female fibers (5.7 vs. 2.8 mN). 4.) Patients with a BMI between 18 till 25 develop significant more force than those with a BMI > 30: Females 5.1 vs. 2.6 mN; p 0.03, Males 3.8 vs. 0.8 mN; p 0.04). Our data suggest that female patients undergoing AVR or CABG

The cause of diabetes in morbidly obese patients is multifactorial, including genetic, social, and dietary components. Transcription factor 7-like 2 (TCF7L2) is a gene that is related to the development of diabetes. This pilot study examines TCF7L2 expression in liver samples obtained from morbidly obese patients undergoing bariatric surgery. TCF7L2 expression is compared between diabetic and nondiabetic patients. Liver samples were obtained from 20 morbidly obese patients undergoing bariatric surgery. Samples were flash frozen in liquid nitrogen. Total RNA was extracted from tissue samples using the TRIzol reagent (Invitrogen Inc, Carlsbad, CA). Using the iScript cDNA synthesis kit (Bio-Rad Laboratories, Hercules,CA), cDNA was synthesized. Quantitative polymerase chain reaction (qPCR) was done using SYBR Green qPCR Reagents (Stratagene, Cedar Creek TX) and the 7300 Real-Time PCR system (Applied Biosystems, Foster City CA). Preoperative demographic and gene expression data were correlated using univariate analysis and logistic regression models. Only associations with a p-value less than 0.05 were considered significant. For the entire group, there was no correlation between body mass index (BMI) and TCF7L2 expression. In morbidly obese nondiabetic patients, there was a positive correlation between TCF7L2 expression and BMI (R(2)=0.21). In morbidly obese diabetic patients, there was an inverse correlation between TCF7L2 expression and BMI (R(2)=0.58). There was no significant relationship between TCF7L2 expression and age or glycosylated hemoglobin (HbA1c). The cause of diabetes is multifactorial but the data from our pilot study documents the relationship of TCF7L2 with type 2 diabetes in morbidly obese patients.

A plethora of papers have been written regarding postcatheterization femoral pseudoaneurysms. However, literature is lacking on pseudoaneurysmal management in patients undergoing coronary artery bypass grafting (CABG). Thus, we examined if pseudoaneurysms with subsequent CABG can be managed with the same strategies as those not exposed to the intense anticoagulation accompanying CABGs. During a 14-year study period, we retrospectively examined femoral iatrogenic pseudoaneurysms (IPSAs) diagnosed postheart catheterization in patients having a subsequent CABG. Patient information was obtained from electronic medical records and included pseudoaneurysm characteristics, treatment, and resolution. Outcomes of interest included the occurrence of IPSA treatment failures and complications. In the 66 patients (mean age, 66 ± 11 years, 46% male) meeting inclusion criteria, mean dose of heparin received during the CABG procedure was 34 000 ± 23 000 units. The IPSA size distribution was the following: 17% of IPSAs measured 3 cm. Pseudoaneurysms were managed with compression, duplex-guided thrombin injection, and surgical repair (1%, 27%, and 26% of cases, respectively). Thrombin injection and surgical repair were 100% effective at treating pseudoaneurysms, with 1 patient experiencing a surgical site infection postsurgical repair. Observation-only management was employed in 30 (45%) patients. Nine of 30 patients with no intervention beyond observation had duplex documented resolution/thrombosis during follow-up. One patient initially managed by observation required readmission and surgical repair of an enlarging pseudoaneurysm (6 cm growth) following CABG. Management of pseudoaneurysms in patients prior to CABG should be similar to those patients not undergoing intense anticoagulation. In appropriate cases, small aneurysms can be safely observed, while thrombin injections are effective and safe as well. Thus, routine open surgical repair is not routinely required in patients

Dipyridamole-thallium imaging has been suggested as a method of preoperatively assessing cardiac risk in patients undergoing major surgery. To define more clearly its proper role in preoperative assessment, we prospectively evaluated 111 patients undergoing vascular surgery. In the first set of 61 patients, our data confirmed the value of preoperative dipyridamole-thallium scanning in identifying the patients who suffered postoperative ischemic events. Events occurred in eight of 18 patients with reversible defects on preoperative imaging, compared with no events in 43 patients with no thallium redistribution (confidence interval for the risk difference: 0.624, 0.256). The results also suggested that clinical factors might allow identification of a low-risk subset of patients. To test the hypothesis that patients with no evidence of congestive heart failure, angina, prior myocardial infarction, or diabetes do not require further preoperative testing, we evaluated an additional 50 patients having vascular procedures. None of the 23 without the clinical markers had untoward outcomes, while ten of 27 patients with one or more of these clinical markers suffered postoperative ischemic events (confidence interval for the risk difference: 0.592, 0.148). In the clinical high-risk subset, further risk stratification is achieved with dipyridamole-thallium scanning

We used {sup 18}F-FDG PET to evaluate the FDG uptake in patients with aggressive fibromatosis (AF, also known as desmoid tumours) undergoing therapy with imatinib (imatinib mesylate, Glivec). The pilot study included nine patients with progressive AF receiving oral treatment with imatinib at a daily dose of 800 mg. Patients were examined using PET prior to the start of therapy and during imatinib treatment. Restaging according to the Response Evaluation Criteria in Solid Tumors (RECIST) was performed in parallel using CT and/or MRI and served as reference. The clinical outcomes in nine evaluable patients were as follows: seven patients with stable disease, and two patients with progressive disease. A 27% decrease in the median average standardized uptake value (SUV) of the sequential PET examinations was demonstrated in all evaluable patients with three patients (33%) showing a decrease in SUV of more than 40% (48%, 52% and 54%, respectively); no patient showed a substantial increase in SUV. To our knowledge, this is the first series of AF patients undergoing treatment with imatinib and monitored using sequential PET imaging, that allows detection of SUV changes after imatinib induction, thus helping to decide whether treatment should be continued or not.

Pre-existing donor-specific HLA antibodies in patients undergoing HLA-mismatched SCT have increasingly been recognized as a risk factor for primary graft failure. However, the clinical implications of the presence of HLA antibodies in donors remain unknown. We prospectively examined 123 related donors for the presence of HLA antibodies by using a Luminex-based single antigen assay. Of these, 1/57 (1.8%) male, 6/27 (22%) parous female and 0/39 (0%) nonparous female donors were HLA antibody-positive. Then, we determined the presence of HLA antibodies in seven patients who received SCT from antibody-positive donors. Of these, four became HLA antibody-positive after SCT. The specificities of the antibodies that emerged in the patients closely resembled those of the antibodies found in the donors, indicating their production by donor-derived plasma cells. Moreover, the kinetics of the HLA antibody levels were similar in all four patients: levels started increasing within 1 week after SCT and peaked at days 10-21, followed by a gradual decrease. These results suggest that donor-derived HLA antibody production frequently occurs in patients undergoing SCT from antibody-positive donors. Further studies are warranted for clarifying the clinical significance of donor-derived HLA antibodies, including the role of these antibodies in post transplant platelet transfusion refractoriness.
