Abstract
INTRODUCTION Systemic lupus erythematosus (SLE) causes kidney compromise in up to 40% of patients, contributing significantly to morbidity. Lupus nephritis (LN), an early onset manifestation in most patients, is histologically classified into six types, with types III, IV, and V requiring treatment with induction therapies, usually glucocorticoids with mycophenolate mofetil (MMF) or intravenous cyclophosphamide (IVC). However, up to 60% of patients fail to achieve complete remission, and 27%-66% have subsequent flares. There is scarce literature on the superiority of IVC or MMF in the Latin population. METHODOLOGY A retrospective cohort study of 72 LN patients at a high-complexity hospital in Chile between 2016 and 2021 was conducted. Demographics, urine studies, creatinine levels, complement levels, antibody profiles, biopsy results, and response to treatment were analysed. RESULTS The median age of the cohort was 29 years, with women representing 90% of patients. At diagnosis, 87.5% of the patients presented with proteinuria, 55% had haematuria, and 49% had acute kidney injury. The most common LN type was type IV. For induction therapy, half of the patients were treated with IVC, and the other half with MMF. The response to treatment did not differ significantly between the two. DISCUSSION This is one of the few studies to focus on the Latin American population, specifically Chile. These results are consistent with the current understanding of LN treatment. Despite its limitations, this study provides valuable insights into the treatment effectiveness of IVC and MMF in this population. CONCLUSION This study did not find significant differences in the clinical response to IVC or MMF at 6 months. Future prospective studies are required to determine the optimal induction therapy for LN, especially in Latin populations.

Can communities be mobilised to build capacity to respond to the COVID-19 pandemic? A qualitative process evaluation. BMJ Open 2024; 14:e078671. [PMID: 38594188 PMCID: PMC11015247 DOI: 10.1136/bmjopen-2023-078671] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/08/2023] [Accepted: 03/18/2024] [Indexed: 04/11/2024] Open
Abstract
OBJECTIVES Government guidance to manage COVID-19 was challenged by low levels of health and digital literacy and lack of information in different languages. 'Covid Confidence' sessions (CC-sessions) were evaluated to assess their effectiveness in counteracting misinformation and provide an alternative source of information about the pandemic. DESIGN We worked with community anchor organisations to co-ordinate online CC-sessions serving three economically deprived, ethnically mixed, neighbourhoods. We conducted a qualitative, participatory process evaluation, in tandem with the CC-sessions to explore whether a popular opinion leader/local champion model of health promotion could mobilise pandemic responses. Group discussions were supplemented by final interviews to assess changes in community capacity to mobilise. SETTING Sheffield, England, September 2020 to November 2021. PARTICIPANTS Community leaders, workers and volunteers representing a variety of local organisations resulted in 314 attendances at CC-sessions. A group of local health experts helped organisations make sense of government information. RESULTS CC-sessions fostered cross-organisational relationships, which enabled rapid community responses. Community champions successfully adapted information to different groups. Listening, identifying individual concerns and providing practical support enabled people to make informed decisions on managing exposure and getting vaccinated. Some people were unable to comply with self-isolation due to overcrowded housing and the need to work. Communities drew on existing resources and networks. CONCLUSIONS CC-sessions promoted stronger links between community organisations which reduced mistrust of government information. In future, government efforts to manage pandemics should partner with communities to codesign and implement prevention and control measures.

Fracture Resistance of Chairside CAD/CAM Lithium Disilicate-reinforced Ceramic Occlusal Veneers With and Without Margin and Full Coverage Crowns. Oper Dent 2024; 49:84-90. [PMID: 38058016 DOI: 10.2341/23-043-l] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 07/31/2023] [Indexed: 12/08/2023]
Abstract
OBJECTIVE The aim of this investigation was to compare the fracture resistance of chairside computer-aided design and computer-aided manufacturing (CAD/CAM) lithium disilicate-reinforced ceramic occlusal veneers with and without margin and traditional full coverage premolar crowns. METHODS AND MATERIALS A total of 60 chairside CAD/CAM lithium disilicate-reinforced ceramic (Amber Mill, Hass Bio) restorations were designed and fabricated with a chairside CAD/CAM system (CEREC Dentsply Sirona). The restorations were divided into three groups (n=20): 1) occlusal veneer with 1.0-mm uniform occlusal thickness and with chamfer margin; 2) occlusal veneer with 1.0-mm uniform occlusal thickness and without margin; and 3) full coverage crown with uniform occlusal thickness and gingival margin. Occlusal veneers and crowns were cemented with dual cured resin luting cement (Multilink, Ivoclar Vivadent) to printed resin dies, load cycled (5 million load cycles at 1 Hz with 275 N force), and then loaded until fracture. Load at break (LB) and peak load (PL) until fracture were recorded. Scanning electron microscope images of the tested restorations on the abutments were obtained. RESULTS Fracture strengths were different depending on the design of the restoration. There was no significant difference in fracture strength between the two types of occlusal veneer (LB: 1132.45 N; PL: 1143.30 N for veneers with margin; LB: 1149.25 N; PL: 1219.05 N for veneers without margin). Full coverage crowns showed the lowest fracture resistance (LB: 936.26 N, PL: 976.42 N), which was significantly lower than both designs of occlusal veneer. CONCLUSIONS The fracture resistance of the CAD/CAM lithium disilicate-reinforced ceramic restorations was influenced by the design. Occlusal veneers with and without margin displayed higher fracture resistance than traditional crowns.

The LIFR Inhibitor EC359 Effectively Targets Type II Endometrial Cancer by Blocking LIF/LIFR Oncogenic Signaling. Int J Mol Sci 2023; 24:17426. [PMID: 38139260 PMCID: PMC10744027 DOI: 10.3390/ijms242417426] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/28/2023] [Revised: 12/01/2023] [Accepted: 12/08/2023] [Indexed: 12/24/2023] Open
Abstract
Endometrial cancer (ECa) is the most common female gynecologic cancer. When comparing the two histological subtypes of endometrial cancer, Type II tumors are biologically more aggressive and have a worse prognosis than Type I tumors. Current treatments for Type II tumors are ineffective, and new targeted therapies are urgently needed. LIFR and its ligand, LIF, have been shown to play a critical role in the progression of multiple solid cancers and therapy resistance. The role of LIF/LIFR in the progression of Type II ECa, on the other hand, is unknown. We investigated the role of LIF/LIFR signaling in Type II ECa and tested the efficacy of EC359, a novel small-molecule LIFR inhibitor, against Type II ECa. The analysis of tumor databases has uncovered a correlation between diminished survival rates and increased expression of leukemia inhibitory factor (LIF), suggesting a potential connection between altered LIF expression and unfavorable overall survival in Type II ECa. The results obtained from cell viability and colony formation assays demonstrated a significant decrease in the growth of Type II ECa LIFR knockdown cells in comparison to vector control cells. Furthermore, in both primary and established Type II ECa cells, pharmacological inhibition of the LIF/LIFR axis with EC359 markedly decreased cell viability, long-term cell survival, and invasion, and promoted apoptosis. Additionally, EC359 treatment reduced the activation of pathways driven by LIF/LIFR, such as AKT, mTOR, and STAT3. Tumor progression was markedly inhibited by EC359 treatment in two different patient-derived xenograft models in vivo and patient-derived organoids ex vivo. Collectively, these results suggest LIFR inhibitor EC359 as a possible new small-molecule therapeutics for the management of Type II ECa.

Early Intraluminal Frozen Elephant Trunk Stent Graft Thrombosis After Aortic Arch Surgery. Ann Thorac Surg 2023; 116:450-457. [PMID: 36608753 DOI: 10.1016/j.athoracsur.2022.12.030] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/02/2022] [Revised: 11/15/2022] [Accepted: 12/06/2022] [Indexed: 01/05/2023]
Abstract
BACKGROUND Partial intraluminal thrombosis of the frozen elephant trunk (FET) stent graft is a poorly described but not infrequent complication after aortic arch surgery. This study aims to describe and analyze the occurrence of early FET stent graft thrombosis. METHODS Retrospective single-center analysis including patients who underwent aortic arch replacement with FET technique between 2006 and 2020. Stent graft thrombosis was diagnosed through computed tomography scan. Several computed tomography scan parameters and clinical variables were analyzed as predictors of this event. RESULTS A total of 125 patients were included for analysis. Among these, 21 (16.8%) patients developed early postoperative FET stent graft thrombosis. Mean volumetric size of the aorta was 12.2 ± 2.0 mL in patients with FET stent graft thrombosis and 10.1 ± 2.8 mL in patients without thrombosis (P < .01). Thrombosis occurred more frequently among patients requiring thoracic endovascular aortic repair completion (15 of 21 [71.4%] patients) than in patients with completely excluded aneurysms (6 of 21 [28.6%] patients) (P = .01). Mean stent-to-aneurysm diameter ratio was 0.8 ± 0.2 among patients with thrombosis and 1.0 ± 0.2 among patients without thrombosis (P < .01). Thrombosis was more frequently observed among patients with conservative management of postoperative bleeding (P = .04). Patients with early FET thrombosis had a nonsignificantly higher in-hospital all-cause mortality than patients without thrombosis (19.0% vs 8.7%; P = .3). CONCLUSIONS Early postoperative intraluminal thrombosis is a frequent complication post FET surgery. Smaller stent graft sizes, larger or partially covered aneurysms, and major bleeding are associated with early thrombosis. Slight FET oversizing, prompt thoracic endovascular aortic repair completion, and early reintervention for major bleeding may prevent early thrombosis.

Deficiency of ataxia-telangiectasia mutated kinase attenuates Western-type diet-induced cardiac dysfunction in female mice. Physiol Rep 2022; 10:e15434. [PMID: 36117462 PMCID: PMC9483716 DOI: 10.14814/phy2.15434] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/09/2022] [Revised: 07/29/2022] [Accepted: 08/05/2022] [Indexed: 11/24/2022] Open
Abstract
Chronic consumption of Western-type diet (WD) induces cardiac structural and functional abnormalities. Previously, we have shown that WD consumption in male ATM (ataxia-telangiectasia mutated kinase) deficient mice associates with accelerated body weight (BW) gain, cardiac systolic dysfunction with increased preload, and exacerbation of hypertrophy, apoptosis, and inflammation. This study investigated the role of ATM deficiency in WD-induced changes in functional and biochemical parameters of the heart in female mice. Six-week-old wild-type (WT) and ATM heterozygous knockout (hKO) female mice were placed on WD or NC (normal chow) for 14 weeks. BW gain, fat accumulation, and cardiac functional and biochemical parameters were measured 14 weeks post-WD. WD-induced subcutaneous and total fat contents normalized to body weight were higher in WT-WD versus hKO-WD. Heart function measured using echocardiography revealed decreased percent fractional shortening and ejection fraction, and increased LV end systolic diameter and volume in WT-WD versus WT-NC. These functional parameters remained unchanged in hKO-WD versus hKO-NC. Myocardial fibrosis, myocyte hypertrophy, and apoptosis were higher in WT-WD versus WT-NC. However, apoptosis was significantly lower and hypertrophy was significantly higher in hKO-WD versus WT-WD. MMP-9 and Bax expression, and Akt activation were higher in WT-WD versus WT-NC. PARP-1 (full-length) expression and mTOR activation were lower in WT-WD versus hKO-WD. Thus, ATM deficiency in female mice attenuates fat weight gain, preserves heart function, and associates with decreased cardiac cell apoptosis in response to WD.

Abstract
PURPOSE Patients with hereditary hypophosphatemic rickets are short and disproportionate and very little information is available on segmental growth, but the body disproportion at adulthood leads us to think that the growth velocity of legs is slower. METHODS A total of 96 children were included and molecular testing was carried out in 42. Children who reached adult height were classified into two groups according to their compliance to conventional treatment (phosphate supplement and calcitriol). Individual growth records of height and sitting height/height were plotted using Argentine reference data in 96 children and growth curves were estimated by fitting Preece-Baines Model 1 in 19 of the children. RESULTS Molecular testing revealed sequence deleterious alterations or large deletions in 36/42 patients. During childhood, 76% of children grew below - 1.88 standard deviation score (SDS) and 97% had body disproportion. During adolescence, the mean peak height velocity for the good and poor compliance to treatment groups was 7.8 (0.6) and 5.4 (0.4) cm/year in boys and 7.0 (0.7) and 5.2 (0.8) cm/year in girls, respectively. At adulthood, the median sitting height/height ratio was 2.32 and 6.21 SDS for the good and poor compliance to treatment groups, respectively. The mean pubertal growth spurt of the trunk was -0.8 (1.4) SDS, with a short pubertal growth spurt of - 1.8 (0.4) SDS for limbs in the good compliance group. Median adult height in 13/29 males and 30/67 females was -4.56 and -3.16 SDS, respectively. CONCLUSION For all patients the growth spurt was slower, secondary to a short growth spurt of limbs, reaching a short adult height with body disproportion that was more prominent in the poor compliance group.

Abstract
1571 Background: Mobile applications have changed the way that users access information and revolutionized healthcare by allowing patients to educate themselves regarding their diagnosis and treatment. Challenges in developing a mobile health application include patient satisfaction and usage over time. Barriers to usage include trust, personalization, and accessibility. Investigating the patient population’s preferences on app content and ease of use is imperative. The use of mobile applications specifically for Latina Gynecologic Oncology patients undergoing treatment has yet to be investigated. Methods: Fifty-six patients were recruited from the Gynecologic Oncology clinic at an urban academic health sciences center located on the Texas-Mexico border. Cross-sectional analyses were performed. Subjects were asked a series of 10-point Likert scale questions including how comfortable they would feel using medical applications on their smartphones. Linear regression models were fit with this scale score as the outcome. Results: The age of the 56 patients ranged from 28 to 77 years with a mean of 53.9 years (SD: 11.1). Spanish was the preferred language of 53.8% of the patients (28/52). Forty-four subjects were available for the regression analyses. Subjects were asked, “Would you feel comfortable using medical applications on your smartphone,” where 1 represented “not at all comfortable” and 10 represented “very comfortable”. The mean comfort scale score was 7.39 (SD: 2.85). Thirty of the 44 subjects (68.2%) replied “Multiple times per day” to the question about how frequently they use mobile apps on their phone. After controlling for the patient’s age in a regression model, patients who used mobile apps multiple times per day had an average comfort scale score that was 1.75 points higher than that of women who did not use mobile apps on their phone multiple times per day (p = 0.03). After adjusting for the frequency of mobile app use, there was a reduction of 0.11 points (p = 0.002) in the comfort scale score for every one year increase in the patient’s age. Conclusions: Our unique pilot study found a positive association between the frequency of current app use and anticipated comfort in using smartphone medical applications. Overall, patients demonstrated a considerable amount of comfort with the prospect of using a mobile app. These findings support the idea of creating a mobile app designed to monitor Latina Gynecologic Oncology patients in efforts to lessen patients’ postoperative burden, improve mortality and morbidity outcomes, and decrease health care system costs.[Table: see text]

Abstract
OBJECTIVES Severe left ventricular dysfunction (LVD) is associated with increased risk following coronary artery bypass grafting (CABG). Due to a dearth of reports on the choice of CABG technique in patients with LVD, this study aims to compare the outcomes of off-pump CABG (OPCAB) and conventional CABG (ONCAB) in such patients. METHODS Retrospective single-centre propensity-matched analysis comparing early- and long-term outcomes of OPCAB and ONCAB in patients with severe LVD. Primary outcome was long-term all-cause mortality. RESULTS Between 2002 and 2014, a total of 1161 consecutive patients with severe LVD underwent isolated CABG [442 patients underwent OPCAB and 719 ONCAB (430 matched pairs)]. Incomplete revascularization was observed more frequently among OPCAB than ONCAB patients (35.3% vs 21.6%; P < 0.01). The overall 30-day mortality was 5% and was comparable between the matched groups [OR 0.64 (0.34-1.22); P = 0.18]. OPCAB patients had shorter median hospital stay (11 vs 12 days; P = 0.02) and lower packed red blood cell transfusion rates [2.7 (2.21-3.19) vs 4.4 (3.56-5.24); P < 0.01]. Estimated adjusted survival was 86.0% vs 85.8%, 69.1% vs 65.5% and 59.9% vs 49.1% at 1, 5 and 10 years for OPCAB and ONCAB patients, respectively (P = 0.99). Long-term risk of mortality was similar between groups [hazard ratio (HR) 0.94 (0.66-1.32); P = 0.7]. Incomplete revascularization was weakly associated with increased risk of long-term all-cause mortality [HR 1.33 (0.99-1.77); P = 0.05]. CONCLUSIONS OPCAB is safe and effective in patients with severe LVD. Although incomplete revascularization is more commonly observed in patients undergoing OPCAB, it is not associated with increased late mortality.

Abstract
Decreasing graft rejection and increasing graft and patient survival are great challenges facing liver transplantation (LT). Different T cell subsets participate in the acute cellular rejection (ACR) of the allograft. Cell-mediated immunity markers of the recipient could help to understand the mechanisms underlying acute rejection. This study aimed to analyse different surface antigens on T cells in a cohort of adult liver patients undergoing LT to determine the influence on ACR using multi-parametric flow cytometry functional assay. Thirty patients were monitored at baseline and during 1 year post-transplant. Two groups were established, with (ACR) and without (NACR) acute cellular rejection. Leukocyte, total lymphocyte, percentages of CD4+ CD154+ and CD8+ CD154+ T cells, human leukocyte antigen (HLA) mismatch between recipient-donor and their relation with ACR as well as the acute rejection frequencies were analysed. T cells were stimulated with concanavalin A (Con-A) and surface antigens were analysed by fluorescence activated cell sorter (FACS) analysis. A high percentage of CD4+ CD154+ T cells (P = 0·001) and a low percentage of CD8+ CD154+ T cells (P = 0·002) at baseline were statistically significant in ACR. A receiver operating characteristic analysis determined the cut-off values capable to stratify patients at high risk of ACR with high sensitivity and specificity for CD4+ CD154+ (P = 0·001) and CD8+ CD154+ T cells (P = 0·002). In logistic regression analysis, CD4+ CD154+ , CD8+ CD154+ and HLA mismatch were confirmed as independent risk factors to ACR. Post-transplant percentages of both T cell subsets were significantly higher in ACR, despite variations compared to pretransplant. These findings support the selection of candidates for LT based on the pretransplant percentages of CD4+ CD154+ and CD8+ CD154+ T cells in parallel with other transplant factors.

Abstract
Abstract
Introduction
Right atrial dilation has also been established as a marker of adverse outcomes in pulmonary hypertension (PH), while right atrial mechanics remain relatively understudied.
Purpose
Transthoracic echocardiography is a practical and widely used tool for risk stratification in PH. We hypothesized that right atrial (RA) strain components [RA reservoir function (ƐR), peak RA contraction (ƐCT) and RA conduit function (ƐCD)] correlates better with strong prognostic parameters as 3D right ventricle ejection fraction (3D RV EF), 6 minutes walking test, systolic pulmonary artery pressure (SPAP) and B-type natriuretic peptide (BNP).
Methods
19 patients with diagnostic PH, type 2 patients were excluded. RA strain was analyzed and determined a correlation with right ventricle function and pulmonary variables.
Results
Morphology correlation was poor with all the variables as SPAP, 6 Minutes walking test, BNP, only RA/LA index has a good correlation with BNP (R = 0.76, P = 0.0004). Right atrial mechanics with strain has good correlation: ƐR correlates with BNP (R= -0.70, P = 0.001) and with SPAP (R= -0.68, P = 0.001). ƐCD correlates with BNP (R=-0.75;P = 0,0002) and with SPAP (R=-0.68, P = 0.001). ƐCT has no correlation with E/e, 3D RV EF, SPAP, pulmonary vascular resistance (PVR), 6 minutes walking test neither BNP. Right atrial deformation sum correlations with 3D RV EF (R= -0.70, P = 0.001), with SPAP (R= -0.72, P = 0.0005), with PVR (R= -0.68, P = 0.001) and with BNP (R=-0.71, P = 0.001).
Conclusion
Right atrium morphological characteristics have poor correlation with variables that evaluate right ventricle function and with variables that predicts outcomes, as BNP, in this patients population. Only RA/LA index as morphology parameter has good correlation with BNP level. Meanwhile right atrial mechanics analyzed by strain has strong correlation with other variables of severity at PH. Right atrial deformation sum has better correlation than other strain parameters in our study.

Abstract
INTRODUCTION Donation after circulatory death (DCD) has increased in the last decade, although a slight increase in surgical complications has been reported in liver transplantation (LT). Therefore, DCD is not overall recommended because it entails an added risk. However, DCD in selected patients shows acceptable results. OBJECTIVE The objective was to analyze the characteristics, early outcomes, and survival at 1 year post-LT from a single institute (January 2015 to May 2017). MATERIALS AND METHODS We included 18 DCD-LTs and compared them with a control group of 18 donation after brain death (DBD) LTs. We analyzed pre- and posttransplant variables related to donors, recipients, and intraoperative early outcomes within patients transplanted due to hepatocellular carcinoma (HCC). A descriptive analysis, Mann-Whitney U test, χ2, or Fisher test was performed when appropriate, as well as multivariate analysis in case of statistical significance. A variable is considered as statistically significant when it reaches a value of P < .05. RESULTS In DBD, we found a lower length of stay in the intensive care unit before retrieval and a higher rate of alcoholism and diabetes mellitus, Model for End-Stage Liver Disease score, and Child B and C score (P < .05). Most of the DCD were originally from the same LT recipient center, and a higher donor mean post-LT alanine aminotransferase level was found (P < .05). Survival for the DBD group was 88% and 75% in the DCD group at 1 year post-LT, being not significant (NS). CONCLUSION HCC recipients who are transplanted with good quality DCD livers do no worse than those transplanted with livers from DBD donors, although a good selection of them is crucial.

Burst-Like Subcutaneous Electrical Stimulation Induces BDNF-Mediated, Cyclotraxin B-Sensitive Central Sensitization in Rat Spinal Cord. Front Pharmacol 2018; 9:1143. [PMID: 30364099 PMCID: PMC6191473 DOI: 10.3389/fphar.2018.01143] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/28/2018] [Accepted: 09/21/2018] [Indexed: 11/18/2022] Open
Abstract
Intrathecal administration of brain derived neurotrophic factor (BDNF) induces long-term potentiation (LTP) and generates long-lasting central sensitization in spinal cord thus mimicking chronic pain, but the relevance of these observations to chronic pain mechanisms is uncertain. Since C-fiber activation by a high-frequency subcutaneous electrical stimulation (SES) protocol causes spinal release of BDNF and induces spinal cord LTP, we propose that application of such protocol would be a sufficient condition for generating long-lasting BDNF-mediated central sensitization. Results showed that application of burst-like SES to rat toes produced (i) rapid induction of hyperalgesia that lasted for more than 3 weeks, (ii) early increase of C-reflex activity followed by increased wind-up scores lasting for more than 1 week, and (iii) early increase followed by late decrease in BDNF protein levels and phosphorylated TrkB that lasted for more than 1 week. These changes were prevented by the TrkB antagonist cyclotraxin-B administered shortly before SES, while hyperalgesia was reversed by cyclotraxin-B administered 3 days after SES. Results suggest that mechanisms underlying central sensitization first involve BDNF release of probably neuronal origin, followed by brief increased expression of likely glial BDNF and pTrkB that could switch early phase sensitization into late one.

Matrix Metalloproteinase 1 as a Novel Biomarker for Monitoring Hepatocellular Carcinoma in Liver Transplant Patients. Transplant Proc 2018; 50:623-627. [PMID: 29579870 DOI: 10.1016/j.transproceed.2017.11.061] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/15/2017] [Revised: 10/20/2017] [Accepted: 11/11/2017] [Indexed: 12/17/2022]
Abstract
INTRODUCTION Orthotopic liver transplantation (LT) is considered to be one of the few curative treatments available for early stages of hepatocellular carcinoma (HCC). Alfa-fetoprotein (AFP) is the most-used biomarker for HCC despite low sensitivity and specificity. Matrix metalloproteinase 1 (MMP-1) has been considered to be involved in the process of vascular invasion of the malignant cells. The objective of this study was to assess the use of MMP-1 for the management of HCC patients for LT. METHODS Levels in serum of MMP-1 (ng/mL) and AFP (ng/mL) were assessed in 20 HCC patients (Milan criteria) before and 1, 6, and 12 months after LT. RESULTS There was a strong significant correlation between levels of MMP-1 and levels of AFP (ρ = .954; P ≤ .05). There were statistical differences in the levels of MMP-1 and APF between the pre-transplantation and post-transplantation groups (1 and 12 months). Increments of both markers 6 months after LT compared with the levels 1 month after LT were detected in 4 of the 20 HCC patients. The detection of recurrence by means of imaging was coincident with the increment of both markers 6 months after LT in 3 of those 4 patients. CONCLUSIONS After 12 months of follow-up, levels of MMP-1 were comparable to AFP levels after LT. Levels of both markers increase 6 months after LT in patients showing recurrence, indicating discriminatory power to predict relapse and thus serving as valuable markers for HCC monitoring. MMP-1 could be useful in the management of HCC after LT.

Abstract
Applications using multi-PW lasers necessitate high temporal pulse quality with a tremendous contrast ratio (CR). The first crucial prerequisite to achieve multi-PW peak power is the generation of ultrashort pulses with good spectral phase quality. Second, to avoid any deleterious pre-ionization effect on targets, nanosecond contrast better than 1012 is also targeted. In the framework of the Apollon 10 PW French laser program, we present a high-contrast 10 fs front-end design study to inject highly energetic Ti:sapphire PW lasers. The CR has been measured and analyzed in different time ranges highlighting the different major contributions for each scale.

Abstract
OBJECTIVE Hospital antimicrobial stewardship programmes have achieved savings and a more rational use of antimicrobial treatments in general wards. The purpose of this report is to evaluate the experience of an antimicrobial stewardship programme in an intensive care unit (ICU). DESIGN Prospective interventional, before-and-after study. SCOPE 24-bed medical ICU in a tertiary hospital. INTERVENTION Prospective audit and feedback antimicrobial stewardship programme. ENDPOINTS Antimicrobial consumption, antimicrobial related costs, multi-drug resistant microorganisms (MDRM) prevalence, nosocomial infections incidence, ICU length of stay, and ICU mortality rates were compared before and after one-year intervention. RESULTS A total of 218 antimicrobial episodes of 182 patients were evaluated in 61 team meetings. Antimicrobial stewardship suggestions were accepted in 91.5% of the cases. Total antimicrobial DDD/100 patient-days consumption was reduced from 380.6 to 295.2 (-22.4%; p=0.037). Antimicrobial stewardship programme was associated with a significant decrease in the prescription of penicillins plus b-lactamase inhibitors, linezolid, cephalosporins, and aminoglycosides. Overall antimicrobial spending was reduced by €119,636. MDRM isolation and nosocomial infections per 100 patient-days did not change after the intervention period. No changes in length of stay or mortality rate were observed. CONCLUSIONS An ICU antimicrobial stewardship programme significantly reduced antimicrobial use without affecting inpatient mortality and length of stay. Our results further support the implementation of an antimicrobial stewardship programme in critical care units.

Abstract
BACKGROUND Nursing students, as future professionals, have an enormous impact on the opinion of the rest of the population on topics of organ donation and transplantation (ODT). The objective of this study was to analyze the attitudes of nursing students at the University of Bialystok toward ODT, and to determine the factors that affect ithemt. METHODS Academic year 2011-2012. STUDY POPULATION nursing students at the University of Bialystok. Type of sampling: sampling points during 5 compulsory-attendance nursing courses with >80% fulfillment. Measuring instrument: validated questionnaire (PCID-ODT Rios) filled out anonymously and self-administered. RESULTS Completion rate of 90% (331/367): 58% (n = 191) in favor, 35% (n = 118) undecided, and 7% (n = 22) against. The most important variables were: being in the 1st year (odds ratio [OR], 4.444; 95% confidence interval [CI], 11.627-1.700; P = .002); not knowing any donor (OR, 12.048; 95% CI, 55.555-2.57; P = .018); being in favor of organ donation by a relative (OR, 6.25; 95% CI, 14.705-2.666; P < .001); discussing the topic with friends (OR, 2,785; 95% CI, 5.347-1.447; P = .002); not worried about the possible mutilation of the body after donation (OR, 3.039; 95% CI, 5.882-1.569; P = .001); favorable attitude toward ODT of mother (OR, 3.676 (0.881-1.814; P < .001); accepting other treatment options, such as inhumation (OR, 3.436; 95% CI, 7.092-1.655; P = .001); accepting autopsy after death (OR, 2.141; 95% CI, 4.065-1.126; P = .020); and professing the Catholic religion (OR, 3.436; 95% CI, 8.333-1.410; P = .007). CONCLUSIONS More than 42% of the nursing students were not in favor of organ donation, their attitudes influenced by various psychosocial factors.

Ventilator-associated pneumonia by methicillin-susceptible Staphylococcus aureus: do minimum inhibitory concentrations to vancomycin and daptomycin matter? Eur J Clin Microbiol Infect Dis 2017; 36:1569-1575. [PMID: 28378244 DOI: 10.1007/s10096-017-2970-3] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/01/2017] [Accepted: 03/16/2017] [Indexed: 01/21/2023]
Abstract
The use of vancomycin minimum inhibitory concentration (MIC) as an outcome predictor in patients with methicillin-susceptible Staphylococcus aureus (MSSA) bacteremia has become an important topic for debate in the last few years. Given these previous results, we decided to investigate whether MICs to vancomycin or daptomycin had any effect on the evolution of patients with ventilator-associated pneumonia (VAP) due to MSSA. An observational, retrospective, multicenter study was conducted among patients with MSSA VAP. We analyzed the relationship between vancomycin and daptomycin MICs and early clinical response (72 h), 30-day mortality, intensive care unit (ICU) length of stay (LOS), and duration on mechanical ventilation. Univariate and multivariate analyses were performed. Sixty-six patients from 12 centers were included. Twenty-six patients (39%) had an infection due to MSSA strains with a vancomycin MIC ≥1.5 μg/mL. Daptomycin MIC was determined in 58 patients, of whom 17 (29%) had an MIC ≥1.0 μg/mL. Ten patients (15%) did not respond to first-line treatment. Only daptomycin MIC ≥1.0 μg/mL had a significant association [odds ratio (OR): 30.00; 95% confidence interval (CI): 2.91-60.41] with early treatment failure. The 30-day mortality was 12% (n = 8). Any variable was associated with mortality in the multivariate analysis. None of the variables studied were associated with ICU LOS or duration on mechanical ventilation. In patients with MSSA VAP, vancomycin MIC does not influence the response to antibiotic treatment or the 30-day mortality. Daptomycin MIC was directly related to early treatment failure.

Abstract
The purpose of this study was to assess the effectiveness of silver-embedded surfaces (BactiBlock®) to prevent surface colonization by multi-resistant bacteria (MRB) and to reduce the incidence of MRB colonization and infection in patients admitted to an intensive care unit (ICU). A 6-month prospective observational study in a 24-bed mixed ICU divided into two identical subunits (12 beds each) was designed. Seven solid mobile screens were placed in one of the subunits while in the other cloth screens remained. Solid screens were constructed with high-density polyethylene embedded in Bactiblock®. To evaluate the effectiveness of screens coated with Bactiblock®, number of MRB isolates on screens were compared for 6 months. Likewise, numbers of new patients and ICU-stays with MRB colonization in the two subunits were compared. One hundred forty screen samples were collected in 10-point prevalent days. MRB were detected on 28 (20.0%) samples. Over the 70 samples taken on cloth folding screens, MRB were detected in 25 (35.7%), while only 3 (4.3%) of the 70 samples taken on Bactiblock® screens were positive for MRB (p < 0.001). The unit with Bactiblock® screens presented fewer number of ICU stays with MRB colonization (27.8% vs 47.1%; p < 0.001). No significant differences were found in the global incidence of MRB nosocomial infection. The presence of Bactiblock® embedded in solid folding screens avoided MRB surface colonization and reduced MRB transmission to patients admitted to critical care units, proving to be an useful tool in the control of MRB.

Abstract
BACKGROUND Social cognition refers to the mental processes involved in social interactions. Different aspects, such as the perception of others, self-knowledge, motivation and the cultural context, can modulate empathy responses and moral judgments regarding the actions of others. The National Mental Health Survey (ENSM for its acronym in Spanish) explored aspects of social cognition such as the perception of emotions, empathy and moral judgment in situations in which another person experiences pain. OBJECTIVE To describe the overall findings of the ENSM in relation to the emotional perception and empathic responses to situations where pain is inflicted on others in an intentional or accidental manner. METHODS A total of 3863 people aged 18-96 years old completed the social cognition module. They were asked to identify the emotions expressed in the images of several faces. A modified version of the awareness of social inference test (TASIT) was used. Additionally, the cognitive, affective, and moral elements of empathy were assessed with a modified version of the empathy for pain task (EPT), which uses a sequence of images in which someone is being hurt. RESULTS Happiness was identified by 91.5% of those interviewed; neutral or emotionless faces were identified by 65%; 55% of respondents correctly identified surprise. Only 19.7%, 21.8% and 27.4% could identify negative emotions like fear, disgust and sadness, respectively. When the data were analysed by age, poverty status, and different regions of the country, the results tend to vary. As regards empathy, 73.7% correctly identified intentional actions, and accidental actions were identified by 56.6%. According to the moral judgment of some respondents, even in situations where the pain was caused by accident, there must be some kind of punishment (20.7% deserved a low punishment and 26.8% a moderate one). CONCLUSIONS Noteworthy findings include the high recognition of happiness by the respondents, in contrast to the apparent difficulty in recognising sadness, and paradoxical results regarding punishment and empathy. This should be studied in greater detail, but these results can contribute to a deeper understanding of the complex Colombian social context.

Abstract
BACKGROUND Liver transplantation from living donors (LLD) has become a viable and important source of liver grafts. The objective of this study was to analyze the attitude of nursing students at the Pomeranian Medical University in Poland on donation of live liver, and to determine the factors that affect it. METHODS Academic year 2011-2012, nursing students at a university in Poland, sampling points in 5 compulsory-attendance nursing courses with a completion rate of 80%, validated questionnaire (PCID-DVH Rios) filled out anonymously and self-administered. RESULTS The completion rate was 89% (227/254). Of the 227 students surveyed, 92% (n = 209) were in favor, 6% (n = 14) undecided, and 2% (n = 4) against. When the LLD is not related, 44% (n = 100) of respondents would be in favor. With a positive attitude toward this type of donation, we associated the following variables: 1) age, with the youngest showing a more favorable attitude (P = .006); 2) attitude in favor of living kidney donation (98% vs 85%; odds ratio, 4.950; 95% confidence interval, 9.259-2.652; P = .002); 3) attitude in favor of accepting a family LLD (96% vs 81%; P = .003); 4) discussing donation and transplantation with family (95% vs 87%; P = .043). CONCLUSIONS Ninety-two percent of nursing students at the Pomeranian Medical University in Poland were in favor of live organ donation, an attitude conditioned by various psychosocial factors.

Abstract
Background We present the case of a patient with acute human immunodeficiency virus infection and a thrombotic microangiopathy as the first clinical manifestation, a presentation that has not, to the best of our knowledge, been previously reported. Case presentation A 35-year-old Bolivian man presented with epistaxis and thrombocytopenia. We found microangiopathic anemia, lymphopenia, elevated lactate dehydrogenase, progressive acute renal failure, negative direct antiglobulin test, and normal activity of ADAMTS13. An human immunodeficiency virus ELISA test was negative, with an human immunodeficiency virus viral load of 10,000,000 RNA copies/mL. Antiretroviral therapy and three sessions of therapeutic plasma exchange were able to control thrombotic microangiopathy. Conclusions Hematologic manifestations of human immunodeficiency virus infection are frequent. However, the debut of acute human immunodeficiency virus infection with thrombotic microangiopathy is a rare event. A high index of suspicion and early treatment is required.

Abstract
INTRODUCTION Liver transplantation from living liver donation (LLD) has become an important source of liver grafts. MATERIAL AND METHOD We studied the 2011-2012 academic year attitude of nursing students from a university in Poland. The sampling points were compulsory attendance in the 5 nursing courses. The validated questionnaire was Project Collaborative International Donor-Living Liver Donation Rios. The questionnaire was completed anonymously and was self-administered. RESULTS The completion rate was 89% (440 of 495); 91% (n = 398) were in favor of the related LLD, 8% (n = 37) were undecided, and 1% (n = 5) were against. When the attitude toward LLD is not related, 40% (n = 177) of respondents were in favor. The favorable attitude was associated with the following: consideration of the needs of organs for transplantations are covered (P ≤ .001); attitude in favor toward organ donation and transplantation (ODT) (P = .001); attitude in favor toward LLD (P = .007); attitude in favor of the acceptance of a LLD by a family member (P = .001); discussion of ODT with the family (P ≤ .001); being in favor of donating organs of a relative (P ≤ .001); and being Catholic (P = .003). After multivariate analysis, we observed the following significant correlations: the thought that the needs of transplantation organs are covered (odds ratio [OR] = 4.608; P = .020); being ready to accept a liver from a LLD (OR = 3.125; P = .038); discussion with the family about the subject of donation and transplantation (OR = 3.215; P = .003); and not belonging to any doctrine or religious belief (OR = 11.363; P = .039). CONCLUSIONS In this study 91% of nursing students were in favor of living organ donation.

Abstract
WHAT IS KNOWN AND OBJECTIVE Positive volume balance is related with high mortality in critically ill patients. We describe our experience in the use of tolvaptan in patients with fluid overload. CASE SUMMARY Six patients in the recovery phase from septic shock were included. All patients achieved an increase in diuresis after the first day, with a median fluid balance variation of -2362 (-485 to -3447) mL. At the end of treatment, median fluid balance variation was -9080 (-26,784 to -4395) mL. WHAT IS NEW AND CONCLUSION Tolvaptan could be an option in critically ill patients with fluid overload and resistant or not treatable with conventional diuretics.
