Prior activation of social work team process by pre-admission one-click automatic referral system

Background

Coronary artery disease (CAD) is the leading global cause of mortality. Coronary angiography (CAG) is often performed for CAD patients, and the mean length of stay (LoS) is 4 d. Requests to the social work team (SWT) are often delayed until just before discharge, causing unnecessarily prolonged LoS and reduced chances of obtaining financial support. If the SWT’s support system is activated beforehand for scheduled CAGs, the LoS would be shorter and patients would be relieved of emotional and financial burdens.

Methods

Collaborating with the cardiology and medical informatics departments, a one-click automatic referral system (OARS) was set up (January-May 2021). When cardiologists scheduled a CAG in the outpatient department, an OARS cue popped automatically for the medical aid recipients. The cardiologists could also activate the pre-admission OARS for other patients when necessary. Subsequently, the SWT responded on that day to discuss initiating the financial support process with the candidates. The rate of cardiologists’ pre-admission referral to SWT, decision-making time on financial support provision, and proportion of patients receiving financial support were compared before and after initiating OARS.

Results

After initiating pre-admission OARS, the rate of cardiologists’ pre-admission referral to SWT increased from 17.8% (18/101: mean age, 64.6±12.0 y; 32 females; January-December 2020) to 59.1% (55/93: mean age, 64.0±11.8 y; 29 females; June-December 2021) (p < 0.001). Although the decision-making time to provide financial support did not change significantly (8.4±11.1 vs. 4.7±11.6 d; p = 0.96), the proportion of patients receiving financial support increased (45.5% [46/101] vs. 60.2% [56/93]; p = 0.045).

Conclusions

By enhancing the cardiologists’ pre-admission referral to SWT and success rate of receiving financial support, the proactive strategy of pre-admission OARS benefits CAD patients scheduled for CAG.

Key messages

• By building a proactive referral strategy of pre-admission OARS, more CAD patients scheduled for CAG could obtain timely financial support and be relieved both emotionally and financially by the SWT.

• This pre-admission OARS might be incorporated for more disease entities for patients in need.

[Dynamics of brain CD68+ and stabilin-1+ macrophage infiltration in patients with myocardial infarction]

Te aim of the study was to evaluate the temporal dynamics of brain CD68+ and stabilin-1+ macrophage infltration in patients with fatal myocardial infarction (MI) type 1.

MATERIALS AND METHODS

Te study included 31 patients with fatal MI type I. Te control group comprised 10 patients of 18-40 age group who died from injuries incompatible with life. Patients with MI were divided into two groups. Group 1 comprised patients who died during the frst 72 hours of MI, group 2 comprised patients who died on days 4‒28. Macrophage infltration in the brain was assessed by immunohistochemical analysis. We used CD68 as a marker for the cells of the macrophage lineage and stabilin-1 as an M2-like macrophage biomarker.

RESULTS

In group 1 the number of brain CD68+ macrophages was signifcantly higher than in the control group. In group 2 the intensity of brain CD68+ cells infltration was lower than in group 1 and higher than in the control group. Tere was a small amount of stabilin-1+ macrophages in the brain of healthy people, as well as of patients who died from MI. Tere were no signifcant differences in the number of stabilin-1+ cells between group 1 and group 2. Correlation analysis revealed the presence of positive correlation between the number of CD68 + macrophages in the infarct, peri-infarct, and non-infarct areas of the myocardium and the number of CD68+ macrophages in the brain in patients with MI. Tere were not correlations between the number of CD68 + and stabilin-1+ cells and the presence of diabetes mellitus, history of stroke, history of MI, and pre-infarction angina.

CONCLUSION

Te number of brain CD68+ macrophages signifcantly increased during the frst three days of MI. Te number of brain stabilin-1+ macrophages did not increase and did not differ from the control values. We observed a positive correlation between the number of CD68+ macrophages in the brain and myocardium.

Longitudinal Associations among Depression, substance Abuse, and Crime: A Test of competing Hypotheses for Driving Mechanisms

PURPOSE

Crime, depression, and substance abuse, often co-occur. This study examined competing models considering each problem domain individually as a driving mechanism for the other problems to better understand etiology and inform prevention efforts. Gender differences were also examined.

METHODS

Data were drawn from the Seattle Social Development Project, a multiethnic and gender-balanced urban panel of 808 participants constituted in 1985. Cross- lagged models examined prospective assessments of early (grades 7 & 8) and late (grades 9-12) adolescent internalizing problems, substance use, and delinquency, as well as measures of depression, substance dependence, and crime at early adulthood (ages 21-24) and later adulthood (ages 27-30).

RESULTS

Comparisons of nested models by gender showed (a) continuity in internalizing behaviors/depression, substance use/dependence, and delinquency/crime for both women and men; (b) accounting for continuity, depression did not consistently drive other problems for either women or men; (c) among women, both substance abuse and crime appeared to be important driving mechanisms; and (d) among men, crime emerged as the most pertinent driving mechanism.

CONCLUSION

Findings suggest that externalizing problems may be more important driving mechanisms for depression than vice versa. Preventing crime and substance abuse may have the important added benefit of reducing early adult depression.

Activation of caspase-8 in 3-deazaadenosine-induced apoptosis of U-937 cells occurs downstream of caspase-3 and caspase-9 without Fas receptor-ligand interaction

3-Deazaadenosine (DZA), a cellular methylation blocker was reported to induce the caspase-3-like activities-dependent apoptosis in U-937 cells. In this study, we analyzed the activation pathway of the caspase cascade involved in the DZA-induced apoptosis using specific inhibitors of caspases. In the U-937 cells treated with DZA, cytochrome c release from mitochondria and subsequent activation of caspase-9, -8 and -3 were observed before the induction of apoptosis. zDEVD-Fmk, a specific inhibitor of caspase-3, and zLEHD-Fmk, a specific inhibitor of caspase-9, prevented the activation of caspase-8 but neither caspase-3 nor caspase-9, indicating that caspase-8 is downstream of both caspase-3 and caspase-9, which are activated by independent pathways. zVAD-Fmk, a universal inhibitor of caspases, kept the caspase-3 from being activated but not caspase-9. Moreover, ZB4, an antagonistic Fas-antibody, exerted no effect on the activation of caspase-8 and induction of apoptosis by DZA. In addition, zVAD-Fmk and mitochondrial permeability transition pore (MPTP) inhibitors such as cyclosporin A (CsA) and bongkrekic acid (BA) did not block the release of cytochrome c from mitochondria. Taken together, these results suggest that in the DZA-induced apoptosis, caspase-8 may serve as an executioner caspase and be activated downstream of both caspase-3 and caspase-9, independently of Fas receptor-ligand interaction. And caspase-3 seems to be activated by other caspses including IETDase-like enzyme and caspse-9 seems to be activated by cytochrome c released from mitochondria without the involvement of caspases and CsA- and BA- inhibitory MPTP.

Induction of apoptosis in human leukemia cells by 3-deazaadenosine is mediated by caspase-3-like activity

3-Deazaadenosine (DZA), one of the potent inhibitors of S-adenosylhomocysteine hydrolase, is known to possess several biological properties including an induction of apoptosis. To evaluate a possibility that DZA may be utilized for the treatment of human leukemia, we studied molecular events of cell death induced by DZA in human leukemia HL-60 and U-937 cells. DZA induced a specific cleavage of poly ADP-ribose polymerase (PARP) and an activation of the cysteine protease caspase-3/CPP32 which is known to cleave PARP. DZA-mediated nuclear DNA-fragmentation was completely blocked in the presence of a universal inhibitor of caspases (z-VAD-fmk) or the specific inhibitor of caspase-3 (z-DEVD-fmk) unlike of cycloheximide (CHX). DNA fragmentation was preceded by the lowering of c-myc mRNA in the DZA treated cells. In addition, DZA-induced apoptosis was blocked by pretreatment with adenosine transporter inhibitors such as nitrobenzylthioinosine (NBTI) and dipyridamole (DPD). Taken together, these results demonstrate that DZA-induced apoptosis initiated through an active transport of DZA into human leukemia cells, is dependent on the caspase-3-like activity without de novo synthesis of proteins and possibly involves c-myc down-regulation.

[A study of the effects of health contracts on the performance level for activities of daily living in the hemiplegic patients]

The purpose of this study was to test the effects of health contract on the performance level for activity of daily living (ADL) in the hemiplegic patients. A quasi-experimental research for health contract, which was approved as an effective method of nursing intervention, was attempted to increase the performance of the hemiplegic patients' ADL. As a purpose sample, 69 hemiplegic patients hospitalized at Oriental medicine hospital of K university were taken and divided into the experimental group and the control group by means of random assignment. After Contracting with the experimental group, they were reinforced everyday for 20 minutes. The experimental group and the control group were observed and interviewed for five times at the interval of 3-4 days by the trained nurses for this research. The data Collected through above mentioned methods were compute analyzed by t-test and ANOVA according to the purpose of this study. The data collected through above mentioned methods were computer analyzed by t-test and ANOVA according to the purpose of this study. Strate increased the performance level for ADL than the Control group" was supported (t = 2.96, df = 52.76, p = .004). Sub Hypothesis 1,2,4,5: "The hypothesis that the experimental group with health contract will demonstrate increased the performance level for eating (t = 2.29, df = 42.70, p = .027), personal hygiene and grooming (t = 4.04, df = 43.10, p = .000), dressing (t = 3.32, df = 67, p = .001) and undressing (t = 3.47, df = 48.44, p = .001) than the control group" was supported. Sub Hypothesis 3.6: "The hypothesis that the experimental group with health contract will demonstrate increased the performance level for toiletting (t = .19, df = 67, p = .849) and mobilization (t = .30, df = 67, p = .765) than the control group" was not supported. The conclusion can be that the positive relationship between the nurse and the patient results in the desired performance level for ADL in the hemiplegic patients.

[Methods of suppression of adrenal hyperfunction]

Evolution of the methods for suppression of adrenal hyperfunction has now made it possible to give up bilateral adrenalectomy in favour of portalization of the adrenal blood flow from the left adrenal by its autotransplantation with maintained blood supply into the transverse mesocolon and cryodestruction of the right adrenal. Analysis of the mortality showed two-stage suppression of adrenal hyperfunction to be advisable.
