ABSTRACT

BACKGROUND: The impact of survivorship care plans (SCPs) on the proximal and distal outcomes of adult and childhood cancer survivors, and parent proxies, is unclear. This study aimed to determine the relationship between SCP receipt and these outcomes. METHODS: A cross-sectional survey of adult and childhood cancer survivors (and parent proxies for survivors aged younger than 16 years) across Australia and New Zealand was conducted. Multivariate regression models were fitted to measure the impact of SCP receipt on proximal (unmet information needs and propensity to engage with, and attend, cancer-related follow-up care) and distal outcomes (quality of life and satisfaction with cancer-related follow-up care) with control for cancer history and sociodemographic factors. RESULTS: Of 1123 respondents, 499 were adult cancer survivors and 624 were childhood cancer survivors (including 222 parent proxies). We found that SCP receipt was predictive of greater attendance at, and awareness of, cancer-related follow-up care (adult: odds ratio [OR], 2.46; 95% CI, 1.18-5.12; OR, 2.38; 95% CI, 1.07-5.29; child/parent: OR, 2.61; 95% CI, 1.63-4.17; OR, 1.63; 95% CI, 1.06-2.50; respectively). SCP receipt also predicted fewer unmet information needs related to "follow-up care required" and "possible late effects" (adult: OR, 0.44; 95% CI, 0.20-0.96; OR, 0.29; 95% CI, 0.13-0.64; child/parent: OR, 0.46; 95% CI, 0.30-0.72; OR, 0.57; 95% CI, 0.38-0.85; respectively). In terms of distal outcomes, SCP receipt predicted a better global quality of life for adult cancer survivors (ß, 0.08; 95% CI, -0.01-7.93), proxy-reported health-related quality of life (ß, 0.15; 95% CI, 0.44-7.12), and satisfaction with follow-up care for childhood cancer survivors (OR, 2.93; 95% CI, 1.64-5.23). CONCLUSIONS: Previous studies have shown little impact of SCPs on distal end points. Results suggest that SCPs may be beneficial to cancer survivors' proximal and distal outcomes.

ABSTRACT

BACKGROUND: The Institute of Medicine recommends that survivorship care plans (SCPs) be included in cancer survivorship care. Our meta-analysis compares patient-reported outcomes between SCP and no SCP (control) conditions for cancer survivors. Our systematic review examines the feasibility of implementing SCPs from survivors' and health care professionals' perspectives and the impact of SCPs on health care professionals' knowledge and survivorship care provision. METHODS: We searched seven online databases (inception to April 22, 2018) for articles assessing SCP feasibility and health care professional outcomes. Randomized controlled trials comparing patient-reported outcomes for SCP recipients versus controls were eligible for the meta-analysis. We performed random-effects meta-analyses using pooled standardized mean differences for each patient-reported outcome. RESULTS: Eight articles were eligible for the meta-analysis (n = 1,286 survivors) and 50 for the systematic review (n = 18,949 survivors; n = 3,739 health care professionals). There were no significant differences between SCP recipients and controls at 6 months postintervention on self-reported cancer and survivorship knowledge, physical functioning, satisfaction with information provision, or self-efficacy or at 12 months on anxiety, cancer-specific distress, depression, or satisfaction with follow-up care. SCPs appear to be acceptable and potentially improve survivors' adherence to medical recommendations and health care professionals' knowledge of survivorship care and late effects. CONCLUSION: SCPs appear feasible but do not improve survivors' patient-reported outcomes. Research should ascertain whether this is due to SCP ineffectiveness, implementation issues, or inappropriate research design of comparative effectiveness studies. IMPLICATIONS FOR PRACTICE: Several organizations recommend that cancer survivors receive a survivorship care plan (SCP) after their cancer treatment; however, the impact of SCPs on cancer survivors and health care professionals is unclear. This systematic review suggests that although SCPs appear to be feasible and may improve health care professionals' knowledge of late effects and survivorship care, there is no evidence that SCPs affect cancer survivors' patient-reported outcomes. In order to justify the ongoing implementation of SCPs, additional research should evaluate SCP implementation and the research design of comparative effectiveness studies. Discussion may also be needed regarding the possibility that SCPs are fundamentally ineffective.

ABSTRACT

A fundamental aspect of acute renal ischemia is energy depletion, manifest as a falling level of ATP that is associated with a simultaneous rise in AMP. The energy sensor AMP-activated protein kinase (AMPK) is activated by a rising AMP-to-ATP ratio, but its role in acute renal ischemia is unknown. AMPK is activated in the ischemic heart and is reported to phosphorylate both endothelial nitric oxide synthase (eNOS) and acetyl-CoA carboxylase. To study activation of AMPK in acute renal ischemia, the renal pedicle of anesthetized Sprague-Dawley rats was cross-clamped for increasing time intervals. AMPK was strongly activated within 1 min and remained so after 30 min. However, despite the robust activation of AMPK, acute renal ischemia did not increase phosphorylation of the AMPK phosphorylation sites eNOS-Ser(1177) or acetyl-CoA carboxylase-Ser(79). Activation of AMPK in bovine aortic endothelial cells by the ATP-depleting agent antimycin A and the antidiabetic drug phenformin also did not increase phosphorylation of eNOS-Ser(1177), confirming that AMPK activation and phosphorylation of eNOS are dissociated in some situations. Immunoprecipitation studies demonstrated that the dissociation between AMPK activation and phosphorylation of eNOS-Ser(1177) was not due to changes in the physical associations between AMPK, eNOS, or heat shock protein 90. In conclusion, acute renal ischemia rapidly activates the energy sensor AMPK, which is known to maintain ATP reserves during energy stress. The substrates it phosphorylates, however, are different from those in other organs such as the heart.

ABSTRACT

Diabetic neuropathy is associated with changes in the extracellular matrix of the perineurium, including thickening of the basement membrane of the perineurial cells. Peripheral vascular disease (PVD) is a common vascular condition that can occur in the absence or presence of diabetes. Thickening of the vascular basement membrane of the vasa nervorum is associated with both diabetes and nondiabetic peripheral vascular disease. However, perineurial cell basement membrane (PCBM) thickening in the nondiabetic PVD state has not, until now, been investigated. In this study, 36 nerve fascicles were examined from three patient groups: a diabetic group, a nondiabetic PVD group, and a group free of both PVD and diabetes (control group). PCBM thickness, fascicle size, and myelinated nerve fibre (MNF) density were measured in all three groups. Endoneurial blood vessels were also observed for evidence of morphological changes. The results showed that the thickness of the PCBM is significantly greater in the diabetic group in comparison with both the control and the nondiabetic PVD group, and this increase in thickness is linearly related to fascicle size. The thickness of the PCBM was not significantly different between the nondiabetic PVD and control groups. Although both the nondiabetic PVD and diabetic groups showed a loss of myelinated nerve fibres in comparison with the control group, this loss was statistically greater in the diabetic group. The endoneurial blood vessels of both the diabetic and nondiabetic PVD groups showed evidence of endothelial cell hyperplasia, hypertrophy, and basement membrane reduplication.

ABSTRACT

Enterohemorrhagic Escherichia coli (EHEC) is a prominent, food-borne cause of diarrhea, bloody diarrhea, and the hemolytic uremic syndrome in industrialized countries. Most strains of EHEC carry the locus for enterocyte effacement (LEE) pathogenicity island, but a proportion of isolates from patients with severe disease do not carry LEE and very little is known about virulence factors in these organisms. LEE-negative strains of EHEC typically express Shiga toxin 2 and carry a large plasmid that encodes the production of EHEC hemolysin. In this study, we determined the nucleotide sequence of the transfer region of pO113, the large hemolysin plasmid from LEE-negative EHEC O113:H21 (EH41). This 63.9-kb region showed a high degree of similarity with the transfer region of R64, and pO113 was capable of self-transmission at low frequencies. Unlike R64 and the related dot/icm system of Legionella pneumophila, however, pO113 was unable to mobilize RSF1010. In addition, the pO113 transfer region encoded a novel high-molecular-weight serine protease autotransporter of Enterobacteriaceae (SPATE) protein, termed EpeA. Like other SPATEs, EpeA exhibited protease activity and mucinase activity, but expression was not associated with a cytopathic effect on epithelial cells. Analysis of a second high-molecular-weight secreted protein revealed that pO113 also encodes EspP, a cytopathic SPATE identified previously in EHEC O157:H7. The nucleotide sequences encoding the predicted beta-domains of espP and epeA were identical and also shared significant homology with a third SPATE protein, EspI. Both espP and epeA were detected in several LEE-negative clinical isolates of EHEC and thus may contribute to the pathogenesis of this subset of EHEC.
