The time constants of beat-by-beat heart rate decay for the first 30 seconds (T30) after exercise is a specific index for the vagally mediated component of heart rate recovery. The aim of our study was to determine whether cardiac rehabilitation (CR) can accelerate T30 in patients after coronary artery bypass grafting (CABG) . Thirteen male patients who underwent CABG (aged 60.5±7.7years) were assigned to 7-21 day Phase I CR. Exercise training consisted of 30 minutes of aerobic exercise (bicycle ergometer) at the anaerobic threshold 2 times per day. T30 was measured as the heart rate decay regulated in patients who rested immediately after 5 minutes of pedaling exercise. After CR, T30 significantly improved from 413.3±129.7 to 300.1±124.5 sec (p<0.01) . Peak oxygen uptake (peak V02: 14.0±4.0 16.7±3.2mlin/kg: p<0.01) and heart rate at anaerobic threshold (HR @ AT: 111.9±13.4 103.6±11.7 beatsin: p<0.01) also improved significantly. There was no correlation between ΔT30 (Δ: difference before and after CR) and Δpeak VO2or ΔHR @ AT. These results suggest that CR for patients following CABG accelerates vagally mediated heart rate recovery after dynamic exercise.

Urinary tract infections (UTIs) are among the most common entities in hospitals, accounting for about 40% of nosocomial infections. It is said that more than 80% of UTIs are associated with the use of catheters. The discharge opening of the Uro Bag, a type of urine storing bag, is alive with bacteria. The microorganisms can enter the bag and then bladder, causing UTIs. It can also be said that the longer the catheters are used, the greater the risk of catheter-related UTIs becomes. Furthermore, Pseudomonas aeruginosa, Staphylococcus aureas, Serratia mareescensand other kinds of bacteria that have acquired the resistance to drugs are increasing. The incidence of mixed infections with different organisms are on the rise. Such being the present situation, to prevent UTIS we think that the proper management of urinary catheterization and right use of urethral catheters are of the primary importance. Those health providers who handle catheters frequently need to take every precaution against inadvertently acting as intermediaries in the incidence of nosocomial infectious diseases including catheter-related UTIs. Recently, we reviewed the prophylactic measures which had been taken by our hospital, assessed the findings using the checklist made by the Nosocomial Infection Prevention Committee. Later, we held a seminar and discussed the standardization of prophylactic measures. As a result, the assessment items which were rated low in June marked 100% in September and March. Thus, our efforts have led the hospital employees to deepen their knowledge and understanding of the need to watch out nosocomial infection constantly. For the guidance of employees, we included in the educational program on-the-job training, which proved to be helpful for the trainees to have imagery. To maintain the effect of infection prevention and to keep up the interest awakened in the hospital staff, the holding of seminars and meetings for reviewing on a regular basis are called for.

Specific activities of the working group include reviewing the assessment score sheet of all falls and the preventive measures by degree of risk, making staff education, training, monitoring the implementation of the safety and preventive recommendations for prevention of falls.
The data of all inpatient falls which occurred during one year prior to and one year subsequent to the WG intervention were analyzed.
The incidence of inpatient secondary falls, decreased from 155 to 108 , and reports of level III severe falls, showed a reduction from five cases to three. Statistically, the total percentage of secondary falls incidence decreased from 2.19‰ to 1.54‰.
We therefore concluded that through the activities of the WG, the strengthening of the in-house system to prevent secondary falls, staff education, training, and heightened staff safety awareness have led to a decrease in the total number of primary and secondary inpatient falls.

We evaluated the efficacy of yokukansan-based prescriptions for patients with headache. Forty-five patients with headache (34 migraine, 6 tension-type, and 5 combined headaches), or 6 males and 39 females, mean age 38 (25 to 68) years were treated with yokukansan-based prescriptions according to their Sho diagnosis, for 1 to 24 months. Relationships between headache improvement, and 31 factors including age, sex, height, body weight and other symptoms at first examination, were qualified with multi-dimensional analysis. Factors such as painful eye sensation, back stiffness, eyestrain and irritability were significant indicators of headache improvement. Three of these factors (painful eye sensation, back stiffness and irritability) were the best subset of explanatory variables. Yokukansan-based prescriptions seemed to be effective for “liver-related” headache, and were thought to be useful to relieve a triggering or worsening of headache factors. And to our knowledge, this is the first paper to propose the importance of examinations of the back, when considering yokukansan-based prescriptions.

We encountered a terminally ill patient, who had resigned as hospital nurse soon after she had fallen ill. As a former health professional, she was acting the good patient and performing her part as a member of the family. The patient was suffering social pain, so much so that she seemed to be unable to express what was really on her mind. One day, the ex-nurse gave us her precious nurse pin. It was when it occurred to us that what the patient had said and behaved was an expression of spiritual pain. Then, we started exploring the meaning of what she had said and done and tried to get at the structure of her spiritual pain referring to Murata's three structures of the spiritual pain of terminally ill patients: “time existence,” “relational existence” and “autogenic existence.” Eventually, we found that her behavior to respond to the wish of her family and to keep a good relationship with her physicians, which she herself regarded as social pain, was to sweep away uneasiness about and fear of being left alone, that is, the spiritual pain associated with “relational existence.” We also found that the spiritual pain associated with “time existence” intermingled with her wish to continue to be a nurse as expressed in the handing over of her nurse's pin.

Purpose: Evaluation of the efficacy and safety of sublingual drug administration in palliative care patients lacking the ability to swallow as well as other drug administration routes. Methods: Buprenorphine, 0.1∼0.2mg/dose (n=15) and fentanyl, 0.05∼0.2mg/dose (n=26) were administered sublingually for cancer pain, and midazolam, 0.1mg/kg (n=16) for insomnia respectively. Results: The three drugs were all rapidly absorbed by the oral cavity and showed efficacy in about 90% of patients. No adverse events were observed other than drowsiness, nausea and over production of sputum in patients suffering from dysphagia. Conclusion: Sublingual administration is a viable alternative for maintaining the quality of life of patients not accessible through conventional administration routes in the palliative setting.

PURPOSE: Plasma neurotrophin-3 (NT-3) levels are associated with several neural disorders. We previously reported that neurotrophins were released from salivary glands following acute immobilization stress. While the salivary glands were the source of plasma neurotrophins in that situation, the association between the expression of neurotrophins and the salivary gland under chronic stress conditions is not well understood. In the present study, we investigated whether NT-3 levels in the salivary gland and plasma were influenced by chronic stress. MATERIALS AND METHODS: Expressions of NT-3 mRNA and protein were characterized, using real-time polymerase chain reactions, enzyme-linked immunosorbent assay, and immunohistochemistry, in the submandibular glands of male rats exposed to chronic stress (12 h daily for 22 days). RESULTS: Plasma NT-3 levels were significantly increased by chronic stress (p<0.05), and remained elevated in bilaterally sialoadenectomized rats under the same condition. Since chronic stress increases plasma NT-3 levels in the sialoadenectomized rat model, plasma NT-3 levels were not exclusively dependent on salivary glands. CONCLUSION: While the salivary gland was identified in our previous study as the source of plasma neurotrophins during acute stress, the exposure to long-term stress likely affects a variety of organs capable of releasing NT-3 into the bloodstream. In addition, the elevation of plasma NT-3 levels may play important roles in homeostasis under stress conditions.

This study investigated the difficulties that single caregivers face while providing home health care for a parent while continuing to work. Semi-structured interviews were conducted with 9 single caregivers who balanced working while providing home health care for more than 3 months for a parent discharged from the hospital. The interview contents were inductively analyzed. One core category with 2 factors was extracted, revealing the characteristics of difficulties that single caregivers face while balancing work and providing home health care. The factor [psychological stress associated with care] had the categories [opportunity to provide care] and [an environment where there is no one to take over caregiving. The factor [care reporting system of persons experienced in providing care] had the categories [presence of a person to talk to about troubles] and [areas to watch and respite system]. For single caregivers providing home health care for a parent for 3 months while continuing to work, the care burden was found to increase over time. The presence of a person whom they could talk to when they experienced difficulties influenced their ability both to provide care and to continue working. Establishing a system that allows for cooperation between medical institutions, the workplace, and society is necessary so that single caregivers can more easily provide care for a parent while continuing to work.

BACKGROUND/AIMS: There are no available data about the relationship between ghrelin gene genotypes and early phase of gastric emptying in functional dyspepsia (FD) as defined by Rome III classification. METHODS: We enrolled 74 patients presenting with typical symptoms of FD and 64 healthy volunteers. Gastric motility was evaluated using the 13C-acetate breath test. We used Rome III criteria to evaluate upper abdominal symptoms and self-rating questionnaires for depression (SRQ-D) scores to determine status of depression. The Arg51Gln (346G>A), preproghrelin (3056T>C), Leu72Met (408C>A), Gln90Leu (3412T>A) and G-protein beta3 (825C>T) polymorphisms were analyzed in the DNA from blood samples of enrolled subjects. Genotyping was performed by polymerase chain reaction. RESULTS: There was a significant relationship between the Gln90Leu3412 genotype and SRQ-D score in FD patients (P = 0.009). Area under the curve at 15 minutes (AUC15) value was significantly associated with the Leu72Met408 genotype (P = 0.015) but not with entire gastric emptying. CONCLUSIONS: The Leu72Met (408C>A) single nucleotide polymorphism was significantly associated with early phase of gastric emptying in FD patients. Further studies will be necessary to clarify the association between ghrelin gene single nucleotide polymorphisms and early phase of gastric emptying in FD patients.
