Providing support to psychiatric patients living in the community in Japan: patient needs and care providers perceptions

Background

Social support programs are a critical component of care for psychiatric patients living in community or residential settings. There is little information, however, on how to optimally deliver these services in the Japanese context.

Methods

We selected ten community life support centers for patients with major mental illness and administered questionnaires to 199 pairs of patients and staff members. These questionnaires consisted of twenty-six items from six categories: difficulties with interpersonal relationships; risks to physical well-being; risks to mental health; difficulties with life skills; challenges regarding living conditions; risks towards community safety. For each of these items, patients were asked whether they had experienced difficulties during the previous month, and staff members were asked the extent to which their patients needed support.

Results

The results demonstrated that staff members tended to understate patients' needs regarding chronic medical conditions (p < 0.01), dietary habits (< 0.01), and excessive smoking or alcohol drinking (< 0.05). On the other hand, staff members recognized patients' needs regarding mental health problems to a greater extent than patients themselves (< 0.05).

Conclusion

Results of this study suggest that social services geared towards specific tasks of daily living form an important component of comprehensive care for psychiatric patients living in community settings in Japan.     

Treatment of squamous cell carcinoma of the uterine cervix with radiation therapy alone: long-term survival, late complications, and incidence of second cancers

The objective of this retrospective study was to determine the survival rate, incidence of late complications, and incidence of second cancers when radiation therapy alone is used for carcinoma of the uterine cervix. Between 1971 and 1995, 1495 patients with squamous cell carcinoma of the uterine cervix (stages I-IV) were treated with radiation therapy alone in our hospital. Radiation therapy consisted of a combination of high-dose-rate intracavitary brachytherapy and external beam radiotherapy. The cumulative 5-year survival rates for stages Ib, II, and III/IVa carcinoma were 93.5, 77.0, and 60.3%, respectively, and the 10-year survival rates were 90.9, 74.5, and 56.1%, respectively. Local control rates for stages Ib, II, and III/IVa carcinoma were 92.0, 79.4 and 64.2%, respectively. Eighty-two (5.5%) patients suffered grade III/IV or V (fatal) complications. A second cancer developed in 13 (0.87%) patients. Second cancers were observed most frequently in the rectum (five cases), colon (three cases), and uterine body (two cases). Long-term follow-up data revealed that our method of radiation therapy alone for locally advanced carcinoma of the uterine cervix is effective, with low incidences of late complications and second cancers.     

Clinical study of varicocele: Statistical analysis and the results of long-term follow-up

BACKGROUND: The results of clinical examinations of varicocele and the clinical outcome of varicocelectomy conducted at Tsukuba University Hospital, Tsukuba City, Japan were analyzed. METHODS: The subjects of the present study were sixty-four infertile male patients with varicocele who visited our hospital from 1991 to 1999. A physical examination, semen analysis and hormonal evaluation were performed for each patient. Patients selected their preferred type of treatment (varicocelectomy or conservative treatment) after providing their informed consent. RESULTS: The age of the patients was 34.1 +/- 5.1(mean +/- standard deviation [s.d.]) years, and the infertile duration was 4.2 +/- 3.0 (mean +/- s.d.) years. Fifty-one cases were left-sided; 13 were bilateral. Mean sperm density ( yen 106/mL) was 37.2 for Grade I, 21.3 for Grade II and 9.4 for Grade III. Sperm density was significantly lower in the higher-graded patients (P = 0.008). Varicocelectomy was performed in 31 cases; the postoperative/preoperative ratio of sperm density was significantly higher in the higher-graded varicocele (P = 0.04), and the peak/base ratio of follicle-stimulating hormone (FSH) after luteinizing hormone-releasing hormone (LH-RH) stimulation was significantly decreased after varicocelectomy (P = 0.007). The pregnancy rate in the partners of the varicocelectomized group (60%) was significantly higher than in the conservatively treated group (28%) P = 0.04; the mean follow-up duration was 76.2 months. CONCLUSION: These results show that varicocele should influence spermatogenesis, therefore altered spermatogenesis could be effectively treated by varicocelectomy, and varicocelectomy should induce a higher probability of pregnancy.     

Monoclonal leukocyte antibody does not decrease the injury of transient focal cerebral ischemia in cats.

BACKGROUND AND PURPOSE: We tested the hypothesis that inhibition of leukocyte function by administration of monoclonal antibody 60.3 (MoAb 60.3) improves electrophysiological recovery and decreases injury volume following transient focal cerebral ischemia in cats. METHODS: Halothane-anesthetized cats underwent 90 minutes of left middle cerebral artery and bilateral common carotid artery occlusion followed by 180 minutes of reperfusion. Cats were assigned to receive either 2 mg/kg MoAb 60.3 (n = 8) directed at the CDw18 leukocyte antigen complex or an equal volume of diluent (sterile saline; n = 10) at 45 minutes of ischemia in a blinded fashion. RESULTS: Blood flow to the left temporoparietal cortex decreased to less than 5 ml/min/100 g with ischemia, but was minimally affected on the right side. Postischemic hyperemia occurred in the left caudate nucleus, whereas blood flow in other brain regions returned to control. No region demonstrated delayed hypoperfusion, and there were no differences between groups. Somatosensory evoked potential recorded over the left cortex was ablated during ischemia and recovered to less than 10% of baseline amplitude at 180 minutes of reperfusion in both groups. Left hemispheric injury volume, as assessed by 2,3,5-triphenyltetrazolium chloride staining, was not affected by drug treatment (mean +/- SE values: MoAb 60.3, 37 +/- 5%; placebo, 38 +/- 7% of hemisphere). CONCLUSIONS: Inhibition of leukocyte function with MoAb 60.3 does not afford protection from severe focal ischemia and reperfusion in cats.     

Triple-mutated oncolytic herpes virus for treating both fast- and slow-growing tumors

Oncolytic virus therapy has emerged as a promising treatment option against cancer. To date, oncolytic viruses have been developed for malignant tumors, but the need for this new therapeutic modality also exists for benign and slow-growing tumors. G47∆ is an oncolytic herpes simplex virus type 1 (HSV-1) with an enhanced replication capability highly selective to tumor cells due to genetically engineered, triple mutations in the γ34.5, ICP6 and α47 genes. To create a powerful, but safe oncolytic HSV-1 that replicates efficiently in tumors regardless of growth speed, we used a bacterial artificial chromosome system that allows a desired promoter to regulate the expression of the ICP6 gene in the G47∆ backbone. Restoration of the ICP6 function in a tumor-specific manner using the hTERT promoter led to a highly capable oncolytic HSV-1. T-hTERT was more efficacious in the slow-growing OS-RC-2 and DU145 tumors than the control viruses, while retaining a high efficacy in the fast-growing U87MG tumors. The safety features are also retained, as T-hTERT proved safe when inoculated into the brain of HSV-1 sensitive A/J mice. This new technology should facilitate the use of oncolytic HSV-1 for all tumors irrespective of growth speed.     

Pronociceptive effects of nociceptin/orphanin FQ (13-17) at peripheral and spinal level in mice

The heptadecapeptide nociceptin/orphanin FQ (N/OFQ) is reported to be metabolized by aminopeptidase N and endopeptidase 24.15. In the present study, N/OFQ C-terminal fragments elicited nociceptive responses in the peripheral nociceptors and in the spinal cord, whereas N-terminal fragments had no significant nociception. The nociceptive effect of N/OFQ (13-17) was most potent and remained unchanged in N/OFQ peptide receptor (NOPR) gene knockout mice, indicating that N/OFQ (13-17)-induced nociception is mediated through a novel mechanism independent of the activation of NOPR. This finding was further confirmed by in vitro guanosine 5'-O-(3-[35S]thio)triphosphate binding experiments, in which N/OFQ (13-17) showed no significant binding activity in baculovirus/sf21 cells expressing NOPR together with G protein alpha(i)1-, beta1-, and gamma2-subunits, whereas N/OFQ showed stimulation in a concentration-dependent manner. On the other hand, although a typical bell-shaped dose-response relationship was observed with a wide range of N/OFQ doses in both peripheral and central nociception tests, N/OFQ (13-17) did not show bell-shaped dose-response relationship in the central nociception test. This finding indicates that N/OFQ (13-17), in contrast to N/OFQ, lacks the postsynaptic antinociceptive actions modulating substance P signaling in the spinal cord. Together, our results suggest that C-terminal fragments of N/OFQ have potent nociceptive actions, and N/OFQ (13-17) could have the potential to mediate its actions through a novel mechanism independent of the activation of NOPR in the nociceptors and in spinal synapses.     

Plasma Lactic Acid and Pyruvic Acid Levels in Migraine and Tension-Type Headache

We examined the lactic and pyruvic acid levels in the plasma of 14 patients with migraine, 17 patients with tension-type headache, and 12 normal controls. The lactic and pyruvic acid levels in the plasma of the migraine patients were significantly higher than those of the normal controls (9.6 ± 5.0 mg/dL and 0.51 ± 0.30 mg/dL versus 3.3 ± 1.9 mg/dL and 0.26 ± 0.20 mg/dL, respectively). There were no significant differences in the levels between the patients with tension-type headache and normal controls. Our results suggest that migraine patients may have functional abnormalities in mitochondrial energy metabolism.     

Sludge and stone formation in the gallbladder in bedridden elderly patients with cerebrovascular disease: influence of feeding method

Purpose. The incidence of gallbladder sludge or gallstone formation in bedridden patients with cerebrovascular disease (CVD) remains obscure. The aim of this study was to determine the incidence, relationship to feeding method, and mechanisms of gallbladder sludge and gallstone formation in elderly patients with CVD. Methods. Using ultrasonography, we determined the development of gallbladder sludge and gallstone over a 12-month period, the area of the gallbladder, the gallbladder contractile response to cerulein, and fasting levels of plasma cholecystokinin (CCK) in 40 bedridden elderly patients with CVD. The patients were divided into three groups based on the feeding method: oral ingestion (OI), nasogastric feeding (NF), and total parenteral nutrition (TPN). Results. Gallbladder sludge and gallstone were not observed in any of the 14 OI patients, but occurred in 6 and 1 of the 11 NF patients, and in 14 and 3 of the 15 TPN patients, respectively. Fasting gallbladder areas were significantly larger in the TPN group than in the other two groups. The TPN group showed a marked decrease in cerulein-induced gallbladder contractility. Fasting plasma CCK levels were lower in the TPN group than in the OI group. Conclusions. Our results indicate that elderly patients with CVD confined to bed over long periods are not necessarily at risk of gallbladder sludge or gallstone formation, and the development of these features may be associated with the feeding method. The predisposition of CVD patients on TPN to gallbladder disease is probably caused by failure of gallbladder contraction, resulting from insufficient secretion of CCK and impaired sensitivity of the gallbladder to CCK.
