Purpose
In this study, we assessed the incidence, contributing factors and outcome of prolonged neutropenia above 7 days and of bacteraemia in patients with lymphoma and multiple myeloma who underwent autologous haematopoietic stem cell transplantation (AHSCT) without antibacterial prophylaxis.Methods
This is a retrospective chart review of 190 adult patients who underwent AHSCT between 2005 and 2015 at a Lebanese hospital.Results
Neutropenia of 7 days duration and longer was documented in 66% of the patient population. Through univariate analysis, patients with lymphoma were significantly more likely to have prolonged neutropenia (≥?7 days) compared to those with myeloma. Mucositis above grade 3, diarrhoea and fever were more likely to occur in patients with prolonged neutropenia. Bacteraemia was documented in 12.6% of the patients. Total mortality rate was 3.7%, and that attributed to bacteraemia was 12.5% in the bacteraemia subgroup. Among bacterial isolates recovered from clinical specimens (89 isolates), 70% were Gram-negative, of which 57% were fluoroquinolone susceptible. Ninety-five percent of the Gram-negative bacteria causing bacteraemia were susceptible to fluoroquinolones.Conclusion
Bacterial pathogens causing bacteraemia were still highly susceptible to fluoroquinolones, despite the high prevalence of fluoroquinolone-resistant strains in the general bacterial ecology. Accordingly, the pertinence of fluoroquinolone prophylaxis in the AHSCT setting warrants further investigation. Moreover, continuous surveillance of local antibiograms in this patient population has become a must in an era of preponderant antibiotic resistance.992.

BACKGROUND Prior studies have linked limited literacy to poorer HIV medication adherence, although the precise causal pathways of this
relationship have only been initially investigated.
OBJECTIVE To examine whether social stigma is a possible mediator to the relationship between literacy and self-reported HIV medication
adherence.
DESIGN Structured patient interviews with a literacy assessment, supplemented by medical chart review, were conducted among patients
receiving care at infectious disease clinics in Shreveport, Louisiana and Chicago, Illinois. Literacy was measured using the
Rapid Estimate of Adult Literacy in Medicine (REALM), while stigma was measured using items taken from the Patient Medication
Adherence Questionnaire (PMAQ).
PARTICIPANTS Two hundred and four consecutive patients participated.
RESULTS Approximately one-third of the patients (30.4%) were less than 100% adherent to their regimen, and 31.4% had marginal (7th–8th
grade) or low (≤ 6th grade) literacy. In multivariate analyses, patients with low literacy were 3.3 times more likely to be
non-adherent to antiretroviral regimens (95% CI 1.3–8.7; p < 0.001). Perceived social stigma was found to mediate the relationship between literacy and medication adherence (AOR 3.1,
95% CI 1.3–7.7).
CONCLUSIONS While low literacy was a significant risk factor for improper adherence to HIV medication regimens in our study, perceived
social stigma mediated this relationship. Low literacy HIV intervention strategies may also need to incorporate more comprehensive
psychosocial approaches to overcome stigma barriers. 相似文献

Despite advances in preventive therapy, acute coronary syndromes (ACS) remain a significant cause of morbidity and mortality.
Patient risk varies widely along a spectrum from unstable angina to ST-segment elevation myocardial infarctions (STEMIs) and
can be estimated using risk prediction algorithms. Estimated risk is useful to select therapeutic options ranging from aggressive
medical therapy for patients at low risk to revascularization for high-risk patients in whom bypass or percutaneous coronary
intervention (PCI) is feasible. Appropriate timing of an invasive strategy is crucial, with early intervention maximally benefiting
the highest-risk patients. Facilitated PCI’s role in patients who present with STEMI and the most appropriate timing of interventional
therapy in patients at moderate risk after a non-ST-elevation ACS remain the subject of ongoing debate. 相似文献

Purpose of Review
Psoriatic arthritis is a distinct disorder, separate from rheumatoid arthritis, and first recognized in a thirteenth century Saxon skeleton. It was, however, the monumental work of Verna Wright in the 1950s that led to the acceptance by the American Rheumatism Association (now American College of Rheumatology) in 1964 as a distinct entity. Wright’s work provided the framework for a better understanding of the pathogenic mechanisms operating on this condition, and eventually led to the development of targeted therapy that has proven to be more effective and safe than conventional therapy.Recent Findings
Pathogenesis of psoriatic arthritis has been better delineated in recent years, as well as the use of biological therapy. Recent findings are discussed in detail.Summary
Historical aspects of psoriatic arthritis, recent developments in pathogenesis, and therapy are discussed, and the contributions of Verna Wright to our understanding of the disorder are presented.995.

Purpose of Review
This review focuses on new pathogenesis and clinical-therapeutic aspects of obstetric anti-phospholipid syndrome (ob-APS) in the last 5 years.Recent Findings
The pathogenesis of ob-APS is multifactorial, including placental infarctions, infiltration of inflammatory cells that cause acute and chronic inflammation, leading to uncontrolled inflammation and poor pregnancy outcomes. A preconception counseling and a patient-tailored treatment are fundamental to improve maternal and fetal outcomes. Thanks to conventional treatment, based on low-dose aspirin and heparin, 70% of women with ob-APS can have successful pregnancies. Women with positive anti-phospholipid antibodies (aPL) without clinical manifestations (“aPL carriers”) or with obstetric manifestation not fulfilling ob-APS criteria need to be further investigated in order to assess their best management.Summary
Great interest has been given to drugs that could interact in the pathophysiological mechanisms, such as hydroxychloroquine, statins, and eculizumab. These drugs could be considered for patients refractory to conventional therapy.996.

We hypothesized that serum urate-associated SNPs, individually or collectively, interact with BMI and renal disease to contribute to risk of incident gout. We measured the incidence of gout and associated comorbidities using the original and offspring cohorts of the Framingham Heart Study. We used direct and imputed genotypes for eight validated serum urate loci. We fit binomial regression models of gout incidence as a function of the covariates, age, type 2 diabetes, sex, and all main and interaction effects of the eight serum urate SNPs with BMI and renal disease. Models were also fit with a genetic risk score for serum urate levels which corresponds to the sum of risk alleles at the eight SNPs. Model covariates, age (P = 5.95E?06), sex (P = 2.46E?39), diabetes (P = 2.34E?07), BMI (P = 1.14E?11) and the SNPs, rs1967017 (P = 9.54E?03), rs13129697 (P = 4.34E?07), rs2199936 (P = 7.28E?03) and rs675209 (P = 4.84E?02) were all associated with incident gout. No BMI by SNP or BMI by serum urate genetic risk score interactions were statistically significant, but renal disease by rs1106766 was statistically significant (P = 6.12E?03). We demonstrated that minor alleles of rs1106766 (intergenic, INHBC) were negatively associated with the risk of incident gout in subjects without renal disease, but not for individuals with renal disease. These analyses demonstrate that a significant component of the risk of gout may involve complex interplay between genes and environment. 相似文献

Heat-induced hormesis, the beneficial effect of mild heat-induced stress, increases the average lifespan of many organisms. Yet little is known about the mechanisms underlying this effect. We used nuclear magnetic resonance spectroscopy to investigate the long-term effects of repeated mild heat treatments on the metabolome of male Drosophila melanogaster. 10 days after the heat treatment, metabolic aging appears to be slowed down, and a treatment response with 40 % higher levels of alanine and lactate and lower levels of aspartate and glutamate were measured. All treatment effects had disappeared 16 days later. Metabolic reprogramming has been associated with the life extending effects of dietary restriction. The metabolite changes induced by the hormetic treatment suggest that the positive effects might not be limited to the repair pathways induced, but that there also is a change in energy metabolism. A possible direct link between changes in energy metabolism and heat induced increase in Hsp70 expression is discussed. 相似文献

BACKGROUND
Enhancing patient-centered care and shared decision making (SDM) has become a national priority as a means of engaging patients in their care, improving treatment adherence, and enhancing health outcomes. Relatively little is known about the healthcare experiences or shared decision making among racial/ethnic minorities who also identify as being LGBT. The purpose of this paper is to understand how race, sexual orientation and gender identity can simultaneously influence SDM among African-American LGBT persons, and to propose a model of SDM between such patients and their healthcare providers.METHODS
We reviewed key constructs necessary for understanding SDM among African-American LGBT persons, which guided our systematic literature review. Eligible studies for the review included English-language studies of adults (≥ 19 y/o) in North America, with a focus on LGBT persons who were African-American/black (i.e., > 50 % of the study population) or included sub-analyses by sexual orientation/gender identity and race. We searched PubMed, CINAHL, ProQuest Dissertations & Theses, PsycINFO, and Scopus databases using MESH terms and keywords related to shared decision making, communication quality (e.g., trust, bias), African-Americans, and LGBT persons. Additional references were identified by manual reviews of peer-reviewed journals’ tables of contents and key papers’ references.RESULTS
We identified 2298 abstracts, three of which met the inclusion criteria. Of the included studies, one was cross-sectional and two were qualitative; one study involved transgender women (91 % minorities, 65 % of whom were African-Americans), and two involved African-American men who have sex with men (MSM). All of the studies focused on HIV infection. Sexual orientation and gender identity were patient-reported factors that negatively impacted patient/provider relationships and SDM. Engaging in SDM helped some patients overcome normative beliefs about clinical encounters. In this paper, we present a conceptual model for understanding SDM in African-American LGBT persons, wherein multiple systems of social stratification (e.g., race, gender, sexual orientation) influence patient and provider perceptions, behaviors, and shared decision making.DISCUSSION
Few studies exist that explore SDM among African-American LGBT persons, and no interventions were identified in our systematic review. Thus, we are unable to draw conclusions about the effect size of SDM among this population on health outcomes. Qualitative work suggests that race, sexual orientation and gender work collectively to enhance perceptions of discrimination and decrease SDM among African-American LGBT persons. More research is needed to obtain a comprehensive understanding of shared decision making and subsequent health outcomes among African-Americans along the entire spectrum of gender and sexual orientation.1000.
