Addressing the psychosocial needs of cancer patients: a retrospective analysis of a distress screening and management protocol in clinical care

Background: A growing recognition of the impact of distress on the quality of life and adherence to treatment of cancer patients has been documented. As a result, national guidelines and standards of care mandate providers to implement distress screening protocols to connect patients with psychosocial services. However, limited literature has examined whether distressed patients are referred to care and their needs addressed. This article assessed differences in rates of referral and psychosocial services by demographic factors, clinical characteristics, and distress severity. Potential predictors of these two outcomes were investigated.

Methods: A retrospective analysis of patient data abstracted from electronic medical records of a NCI-designated Academic Comprehensive Cancer Center was conducted. Of the 399 cases meeting the inclusion criteria, 302 (75.7%) were screened for distress with the Distress Thermometer. Differences were examined with chi-square, t-tests, and ANOVAs. Predictors were identified with multivariate logistic regressions.

Results: Overall, patients who were identified as distressed were referred to a psychosocial provider (71.4%) and psychosocial services were delivered in approximately 64% of the cases. Referrals and service delivery rates varied by age group, clinic, health insurance coverage, distress severity, and presence of psychosocial issues. Only the distress score predicted the likelihood of being referred, and of a provider intervention to occur.

Conclusions and implications for psychosocial providers: Although the protocol appeared to facilitate referral and service delivery to patients scoring above the cutoff for distress, our results suggest that patients were more likely to not have their distress and psychosocial needs addressed if they were older, without insurance coverage, and were seen in clinics where a social worker was not consistently available. Future studies able to monitor patient outcomes in terms of quality of life, satisfaction with care, and service utilization are recommended.     

Endophytic fungi harbored in Cannabis sativa L.: diversity and potential as biocontrol agents against host plant-specific phytopathogens

The objective of the present work was isolation, phylogenetic characterization, and assessment of biocontrol potential of endophytic fungi harbored in various tissues (leaves, twigs, and apical and lateral buds) of the medicinal plant, Cannabis sativa L. A total of 30 different fungal endophytes were isolated from all the plant tissues which were authenticated by molecular identification based on rDNA ITS sequence analysis (ITS1, 5.8S and ITS2 regions). The Menhinick’s index revealed that the buds were immensely rich in fungal species, and Camargo’s index showed the highest tissue-specific fungal dominance for the twigs. The most dominant species was Penicillium copticola that could be isolated from the twigs, leaves, and apical and lateral buds. A detailed calculation of Fisher’s log series index, Shannon diversity index, Simpson’s index, Simpson’s diversity index, and Margalef’s richness revealed moderate overall biodiversity of C. sativa endophytes distributed among its tissues. The fungal endophytes were challenged by two host phytopathogens, Botrytis cinerea and Trichothecium roseum, devising a dual culture antagonistic assay on five different media. We observed 11 distinct types of pathogen inhibition encompassing a variable degree of antagonism (%) on changing the media. This revealed the potential chemodiversity of the isolated fungal endophytes not only as promising resources of biocontrol agents against the known and emerging phytopathogens of Cannabis plants, but also as sustainable resources of biologically active and defensive secondary metabolites.

Arch-first technique via clamshell incision: successful surgical reoperation for aortic arch dissection

We report a case of successful reoperation for aortic arch dissection with use of the "arch-first" technique in a patient who had Marfan syndrome. Extracorporeal circulation was initiated via right subclavian artery cannulation, and the chest was entered through a clamshell incision for the best exposure. When the patient was cooled to 18 degrees C, the perfusion was stopped. After the 1st aortic arch anastomosis to a 30-mm Dacron graft, cerebral perfusion was reestablished via the right subclavian artery. The aortic repair was then completed. The cerebral ischemic time was 18 minutes, the aortic cross-clamp time was 69 minutes, and the total extracorporeal circulation time was 334 minutes. The patient was discharged from the hospital on postoperative day 10 with no neurologic impairment. The arch-first technique shortens the duration of brain ischemia. When combined with a clamshell incision, the technique is particularly helpful for reoperation of the aortic arch and thoracic aorta.     

Elevated GLUT 1 level in crude muscle membranes from diabetic Zucker rats despite a normal GLUT 1 level in perineurial sheaths

Summary Recently, we demonstrated that approximately 60 % of GLUT 1 in a crude membrane fraction of rat skeletal muscle originates from perineurial sheaths. To study the in vivo regulation of GLUT 1 expression in different tissues in muscles, we measured the level of GLUT 1 in crude muscle membranes and in perineurial sheaths in diabetic (fa/fa) Zucker rats and lean controls, with and without metformin treatment. The GLUT 1 concentration in perineurial sheaths was identical in all four groups of rats, both when measured by quantitative immunofluorescence and by immunoblotting and densitometry. In a fraction of crude membranes of soleus muscles GLUT 1 expression was more than two-fold higher in (fa/fa) rats than in lean controls (p<0.005). Metformin treatment significantly elevated GLUT 1 in control rats (p<0.05) and tended to decrease GLUT 1 in diabetic rats (p<0.075). The expressions of GLUT 1 and GLUT 4 in crude muscle membranes were inversely correlated (p<0.01), and GLUT 1 expression correlated positively with fasting glucose (p<0.05). In conclusion, GLUT 1 expression in perineurial sheaths is unaffected by alterations in glucose homeostasis and by the genes responsible for obesity and diabetes in the Zucker rat. GLUT 1 expression in a crude membrane fraction of soleus muscle is increased in the diabetic animals, likely due to an increased expression in muscle cells proper.

Neuroprotective effect of edaravone in experimental glaucoma model in rats: a immunofluorescence and biochemical analysis

AIM: To evaluate the neuroprotective activity of systemically administered edaravone in early and late stage of experimental glaucoma in rats. METHODS: In this study, 60 Wistar albino rats were used. Experimental glaucoma model was created by injecting hyaluronic acid to the anterior chamber once a week for 6wk in 46 of 60 subjects. Fourteen subjects without any medication were included as control group. Edaravone administered intraperitoneally 3 mg/kg/d to the 15 of 30 subjects starting at the onset of glaucoma induction and also administered intraperitoneally 3 mg/kg/d to the other 15 subjects starting at three weeks after the onset of glaucoma induction. The other 16 subjects who underwent glaucoma induction was administered any therapy. Retinal ganglion cells (RGCs) have been marked with dextran tetramethylrhodamine (DTMR) retrograde at the end of the sixth week and after 48h, subjects were sacrificed by the method of cardiac perfusion. Alive RGC density was assessed in the whole-mount retina. Whole-mount retinal tissues homogenized and nitric oxide (NO), malondialdehyde (MDA) and total antioxidant capacity (TAC) values were measured biochemically. RESULTS: RGCs counted with Image-Pro Plus program, in the treatment group were found to be statistically significantly protected, compared to the glaucoma group (Bonferroni, P<0.05). The neuroprotective activity of edaravone was found to be more influential by administration at the start of the glaucoma process. Statistically significant lower NO levels were determined in the glaucoma group comparing treatment groups (Bonferroni, P<0.05). MDA levels were found to be highest in untreated glaucoma group, TAC levels were found to be lower in the glaucoma induction groups than the control group (Bonferroni, P<0.05). CONCLUSION: Systemic administration of Edaravone in experimental glaucoma showed potent neuroprotective activity. The role of oxidative stress causing RGC damage in glaucoma was supported by this study results.
