Prediction of Nursing Home Admission Using the FRAIL-NH Scale Among Older Adults in Post-Acute Care Settings.

OBJECTIVES: The FRAIL-NH scale was developed to identify frailty status in nursing home residents. The purpose of this study was to examine the utility of the FRAIL-NH scale for predicting nursing home admission among patients in post-acute care settings. Design/ Setting/ Participants: This single-center, prospective, observational cohort study included participants aged 65 years or older who were admitted to a community-based integrated care ward (CICW) between July 2015 and November 2020. MEASUREMENTS: Using the CICW database, we retrospectively classified participants as robust, prefrail, or frail based on the FRAIL-NH scale the score by identifying variables from our database that were most representative of each component. The following data were collected: examination findings, CICW admission and discharge information, length of CICW stay, and nursing home admission. The participants were divided into two groups based on whether or not they were admitted to a nursing home after CICW discharge. The hazard ratios (HRs) and 95% confidence intervals (CIs) for nursing home admission were calculated according to the FRAIL-NH categories using the Cox proportional hazards models with reference to the robust group. In the multivariate adjusted model, we adjusted for age, sex, nutritional status, cognitive function, living status, and economic status. RESULTS: Data of 550 older adults were analyzed, of which 118 were admitted and 432 were not admitted to a nursing home. The frail group had a higher risk of nursing home admission (HR, 2.22; 95% CI 1.32-3.76) than the robust group. CONCLUSIONS: This study showed that the FRAIL-NH scale was beneficial for predicting nursing home admission among older adults in the post-acute care setting. Thus, assessment using the FRAIL-NH scale may help to consider preparation and support for life after discharge.

Motor cortex and spinal cord neuromodulation promote corticospinal tract axonal outgrowth and motor recovery after cervical contusion spinal cord injury.

Cervical injuries are the most common form of SCI. In this study, we used a neuromodulatory approach to promote skilled movement recovery and repair of the corticospinal tract (CST) after a moderately severe C4 midline contusion in adult rats. We used bilateral epidural intermittent theta burst (iTBS) electrical stimulation of motor cortex to promote CST axonal sprouting and cathodal trans-spinal direct current stimulation (tsDCS) to enhance spinal cord activation to motor cortex stimulation after injury. We used Finite Element Method (FEM) modeling to direct tsDCS to the cervical enlargement. Combined iTBS-tsDCS was delivered for 30min daily for 10days. We compared the effect of stimulation on performance in the horizontal ladder and the Irvine Beattie and Bresnahan forepaw manipulation tasks and CST axonal sprouting in injury-only and injury+stimulation animals. The contusion eliminated the dorsal CST in all animals. tsDCS significantly enhanced motor cortex evoked responses after C4 injury. Using this combined spinal-M1 neuromodulatory approach, we found significant recovery of skilled locomotion and forepaw manipulation skills compared with injury-only controls. The spared CST axons caudal to the lesion in both animal groups derived mostly from lateral CST axons that populated the contralateral intermediate zone. Stimulation enhanced injury-dependent CST axonal outgrowth below and above the level of the injury. This dual neuromodulatory approach produced partial recovery of skilled motor behaviors that normally require integration of posture, upper limb sensory information, and intent for performance. We propose that the motor systems use these new CST projections to control movements better after injury.

Impact of family history of gastric cancer on colorectal neoplasias in young Japanese.

AIM: The aim of this study was to elucidate risk factors for the development of colorectal neoplasia in the young population. In particular, we focused on the family history of gastric cancer. METHOD: Young Japanese subjects aged 30-49 years old who underwent colonoscopy for the first time from August 2007 to August 2008 were included in this study. A total of 300 unselected consecutive patients (mean age 40.5 years) were eligible for analysis, and family history of colorectal cancer and gastric cancer, sex, age, body mass index, positivity of faecal occult blood test and the presence of symptoms were evaluated. Risk factors for developing colorectal adenoma and/or carcinoma were assessed. RESULTS: Colorectal neoplasias were detected in 83 (27.7%) cases. Two were found to have invasive carcinoma. Univariate and multivariate analyses revealed that family history of gastric cancer (OR 2.09, 95% CI 1.12-3.92, P = 0.02) was an independent risk factor for the development of colorectal neoplasia, as well as male sex (OR 1.89, 95% CI 1.10-3.27, P = 0.02), older age (OR 2.05, 95% CI 1.18-3.55, P = 0.01) and positive faecal occult blood test (OR 1.99, 95% CI 1.14-3.48, P = 0.02). CONCLUSION: In the young population under 50 years of age, a family history of gastric cancer is an independent risk factor for the development of colorectal neoplasia.

Disseminated aspergillosis following resolution of Pneumocystis pneumonia with sustained elevation of beta-glucan in an Intensive Care Unit: a case report.

Invasive aspergillosis is a major cause of morbidity and mortality in immunocompromised patients receiving intensive care. The double-sandwich ELISA for galactomannan is reported to have a high sensitivity (96.5%) for the detection of invasive aspergillosis when a cut-off value of 0.8 ng/ml is used. However, we have experienced a case of lethal disseminated aspergillosis in a patient that presented with a negative galactomannan (GM) test and persistent elevation of beta-D glucan (BG) levels. A 63-year-old female was admitted to our Intensive Care Unit (ICU) in acute respiratory failure and elevated BG. She had been receiving medication for Good-pasture syndrome based on anti-glomerular basement membrane antibodies and myeloperoxidase-antineutrophil cytoplasmic antibodies for 9 months and was receiving long-term prednisolone therapy (20 mg/day). On admission, her trachea was immediately intubated, and a PCR analysis of the bronchoalveolar lavage sample revealed Pneumocystis jiroveci. Trimethoprimsulfamethoxazole therapy was started for Pneumocystis pneumonia. The levels of BG remained elevated (> 100 pg/ml) during the treatment period despite the clinical resolution of Pneumocystis pneumonia, raising concerns of another complicated invasive fungal disease; consequently, fosfluconazole was administered empirically. The serum BG levels, however, did not decrease. Blood cultures did not detect a fungal infection. Serum GM levels measured by a double-sandwich ELISA on the 6th, 11th, and 24th days in the ICU were negative (< 0.2 ng/ml). The patient ultimately died of multiple organ failure on the 45th ICU day. Postmortem examination revealed a disseminated fungal infection with aggressive vascular invasion of the lungs, heart, and brain. In situ hybridization with a 568-bp probe of the alkaline proteinase sequence of Aspergillus fumigatus showed specific positive staining within the fungus present in the infected lung tissue, revealing that this patient may have had a systemic infection by A. fumigatus or A. flavus. This is a case of serum GM-negative disseminated aspergillosis pathologically proven by autopsy. Persistent elevated BG levels (> 100 pg/ml) refractory to trimethoprim-sulfamethoxazole and fosfluconazole may suggest possible Aspergillus infection and should prompt the initiation of empiric anti-aspergillosis therapies in patients at risk for fungal infection.

Effect of matrix metalloproteinase-3 functional SNP on serum matrix metalloproteinase-3 level and outcome measures in Japanese RA patients.

OBJECTIVE: A bi-allelic polymorphism on the promoter region, -1612 ins/del A, was found to influence the production of MMP-3. Since MMP-3 plays a particularly pivotal role in joint destruction, the MMP-3 gene is thought to be an interesting target gene of disease severity in RA. We attempt to determine whether the MMP-3 promoter polymorphism is associated with serum titre of MMP-3, disease activity and severity in Japanese RA patients. METHODS: DNA samples were obtained from 1504 RA patients as part of the Institute of Rheumatology Rheumatoid Arthritis observational cohort study. From the 2006 spring data, serum MMP-3 levels of 820 patients were available by enzyme immunoassay. Joint damage score at 5-yr disease duration could be measured using the Sharp/van der Heijde method in 162 patients. Genotyping of -1612 ins/del A was performed using fluorescent-labelled fragment analysis. Differences in serum MMP-3 level and joint damage score among genotypes of -1612 ins/del A polymorphism were analysed by linear regression analysis. RESULTS: No significant differences were found among MMP-3 genotypes on patient characteristics including disease activity score (P = 0.51) or health assessment questionnaire (P = 0.99). A significant effect of risk allele on serum MMP-3 level was observed (P = 0.038), while no significant effect was observed on radiographic joint damage (P = 0.47). CONCLUSION: We conclude that MMP-3 functional polymorphism is associated with serum MMP-3 titre, but is not a direct predictor for outcome measures in Japanese RA patients.

[Surgical stabilization of multiple rib fracture and flail chest].

The experience of 14 cases with surgical stabilization of multiple rib fracture and flail chest was reported. They were 11 men and 3 women of 31 to 87 years of age. Paradoxical chest movement was noted in 10 patients. Thirteen of 14 patients successfully weaned from the ventilator less than 7 days after surgery. Of 14, 4 cases were treated with internal fixation and the others were with acetabular reconstruction plates with or without rib stapler. No case of death was experienced. Ten patients who were performed fixation with acetabular reconstruction plate weaned from the ventilator earlier than cases treated by internal fixation, suggesting the superiority of the acetabular reconstruction plate. Improvement of rib stapler and the development of a titanium plate of specific use for rib is expected in the future.

Patients with extraintestinal manifestations have a higher risk of developing pouchitis in ulcerative colitis: multivariate analysis.

BACKGROUND: Restorative proctocolectomy and ileal pouch-anal anastomosis (IPAA) have been the surgical treatments of choice for ulcerative colitis (UC). However, the IPAA is sometimes complicated with pouchitis. Furthermore, the cumulative risk and risk factors for developing pouchitis in patients with UC undergoing IPAA have not been reported in any Asian population. The aim of our study is to clarify the cumulative risk and risk factors for developing pouchitis in Japanese patients with UC undergoing IPAA. METHODS: Fifty-eight patients with UC undergoing IPAA were retrospectively evaluated for the presence of pouchitis, gender, age of onset, history of smoking, presence of extraintestinal manifestations (EIMs) and type of operation. The diagnosis of pouchitis was based on the pouchitis disease activity index. The cumulative risk and risk factors for developing pouchitis were assessed. RESULTS: The cumulative risks for developing pouchitis at 1 and 5 years were 9.0% and 14.4%, respectively. The estimated risks of pouchitis at 5 years was 48.1% in patients with EIMs and 4.6% in those without. Both univariate and multivariate analyses revealed that the presence of EIMs is a significant risk factor (hazard ratio 16.85, 95% confidence interval 3.12-91.00; P=0.001). CONCLUSIONS: The presence of EIMs is a significant risk factor for the development of pouchitis in Japanese patients with UC undergoing IPAA.

Earlier surveillance colonoscopy programme improves survival in patients with ulcerative colitis associated colorectal cancer: results of a 23-year surveillance programme in the Japanese population.

Patients with long-standing ulcerative colitis (UC) are known to have an increased risk for the development of colorectal cancer (CRC). The aim of this study was to clarify the cumulative risk for the development of dysplasia or invasive cancer and the effectiveness of surveillance colonoscopy in the Japanese population. A total of 217 patients received a total of 1027 surveillance colonoscopies between January 1979 and December 2001 at the University of Tokyo hospital. Patients with invasive cancer found in the surveillance group were compared to those referred to our hospital from the other hospitals without surveillance colonoscopy. Surveillance colonoscopy confirmed 15 patients with definite dysplasia. Of these, five were proved to have invasive cancer in the resected specimens. The cumulative risk for the development of invasive cancer at 10, 20, and 30 years was 0.5, 4.1, and 6.1%, respectively, while that for the development of definite dysplasia at 10, 20, and 30 years was 3.1, 10.0, and 15.6%, respectively. All the patients with invasive cancer in the surveillance group remained alive, while three out of four patients in the nonsurveillance group died. Our surveillance programme is useful for detecting UC-associated CRC, and survival may be improved by surveillance colonoscopy.

Superimposition of post-streptococcal acute glomerulonephritis on the course of IgA nephropathy: predominance of Th1 type immune response.

A 23-year-old man was admitted with macrohematuria and systemic edema appearing after an acute upper respiratory tract infection. He had been diagnosed 6 years earlier with IgA nephropathy (IgA-N). On admission, hypertension, nephrotic syndrome and hypocomplementemia were evident together with a high titer of anti-streptokinase (ASK). Renal biopsy showed severe glomerular mesangial proliferation, segmental endocapillary proliferation and crescent formation. Immunofluorescence microscopy (IF) showed strong deposition of C3 and reduced deposition of IgA. Electron microscopy showed a so-called "hump" on the epithelial side of the glomerular basement membrane. These features were consistent with post-streptococcal acute glomerulonephritis (PSAGN) superimposed on IgA-N. Following 2 weeks of observation, blood pressure, C3 level and ASK titer returned to normal ranges, although nephrotic syndrome was still evident, which necessitated oral prednisolone (30 mg/day) therapy. Another biopsy taken 2 months later demonstrated regression of endocapillary proliferation and IF showed decreased deposition of C3. Immunohistochemical staining of the specimen taken on admission revealed the presence of numerous T cells and macrophages in the interstitium. Macrophages were also seen in the glomerular tuft. Many interstitial infiltrating cells were positive for interferon-gamma, but their number diminished after treatment. Our findings suggest that PSAGN complicating pre-existing IgA-N activates cellular immunity and augments renal tissue injury.

Clinical features and management of hepatic portal venous gas: four case reports and cumulative review of the literature.

HYPOTHESIS: Hepatic portal venous gas (HPVG) has been considered a rare entity associated with a grave prognosis. Since 1978, when Liebman et al reviewed 64 cases of HPVG and reported a mortality of 75%, the number of reported cases has been increasing. DESIGN: Case series. PATIENTS AND METHODS: We reviewed the literature on 182 cases of HPVG in adults, including 4 of our patients, (transplantation and abdominal trauma cases were excluded) and analyzed the cause, pathogenesis, and clinical features. RESULTS: In this series, the underlying clinical events associated with HPVG were bowel necrosis (43%), digestive tract dilatation (12%), intraperitoneal abscess (11%), ulcerative colitis (4%), gastric ulcer (4%), Crohn disease (4%), complications of endoscopic procedures (4%), intraperitoneal tumor (3%), and other (15%). The overall mortality was 39% but varied depending on the underlying disease. CONCLUSIONS: Hepatic portal venous gas is a lethal or curable entity caused by various diseases. The underlying disease associated with HPVG determines the clinical features and prognosis of the patients. The treatment of patients with HPVG should be directed to the underlying disease.

Teratoma in a feline unilateral cryptorchid testis.

A 14- x 12- x 6-cm (approximately 600 g) cryptorchid testis was surgically removed with the omentum from the posterior portion of the abdominal cavity of a 2-year-old male American Shorthair cat. At the time of a previous orchiectomy, a unilateral testis had been discovered in the scrotum. The cut surface of the cryptorchid testis consisted of solid areas with many cysts containing fluid and spongy soft areas. Histologically, the cryptorchid testis was composed of neuroectodermal components and diffuse immature glial tissues, cystic, tubular, and papillary epithelial tissues, and immature cartilaginous tissues. A metastatic mass in the omentum had histologic structures similar to those of the cryptorchid testis. The present case was diagnosed as teratoma in a feline unilateral cryptorchid testis.

Right atrial rupture in blunt chest trauma.

The mortality rate from cardiac rupture by blunt chest injury is high. Here, we report a case of 27-year-old male who suffered a right atrial rupture by blunt chest injury and was successfully treated. The hemodynamics were stabilized by pericardiocentesis with a 5F Pigtail catheter for cardiac tamponade and rapid fluid transfusion. Then the right atrial rupture was repaired without a cardiopulmonary bypass. The postoperative course was uneventful, and the patient was discharged on the 14th postoperative day.

Transcatheter arterial embolization for bone metastases from hepatocellular carcinoma.

The objective of this study was to determine which of the following three methods is the most effective for the treatment of bone metastases from hepatocellular carcinoma (HCC): transcatheter arterial embolization (TAE); combination of TAE and external radiotherapy; or external radiotherapy alone. Thirty-nine metastatic bone lesions from HCC in 33 patients were retrospectively reviewed. Each lesion underwent either TAE alone (group A, n = 11), TAE followed by radiotherapy (group B, n = 17), or radiotherapy alone (group C, n = 11). They were evaluated on the following subjects: pain relief; improvement of daily activities; and complications. Each treatment was effective for pain relief (89-94%) and improvement of daily activities (73-82%). The mean time interval from the beginning of each treatment to the onset of initial pain relief was 4.7 days in group A, 4.8 days in group B, and 15 days in group C. Recurrence of the pain after the initial pain relief was noted in 75% in group A, 20% in group B, and 88% in group C. Pyrexia and local pain commonly occurred after TAE. In conclusion, TAE is effective in relieving pain immediately and in improving the patients' daily activities. The combination of TAE and radiotherapy is recommended for permanent pain relief.

[Anesthetic management of a patient with congenital antithrombin III Deficiency using temporal inferior vena cava filter].

We described the perioperative management of a patient with congenital antithrombin III deficiency using temporal inferior vena cava filter. A 30-year-old man with congenital antithrombin III deficiency was scheduled for artificial head replacement of the hip joint under general anesthesia. He was diagnosed as having congenital antithrombin III deficiency when he had had an episode of venous thrombosis after artificial head replacement of the right hip joint. He had been taking warfarin as an anticoagulant, and it was discontinued three days before surgery. To prevent perioperative thrombus formation, the plasma AT III activity was maintained above 80% before, during and after surgery using AT III concentrates. We also placed the temporal inferior vena cava filter. There was no serious thrombosis or embolism perioperatively. The use of the filter during the perioperative period helped to avoid development of serious thrombosis and embolism.

Intestinal perforation due to metastasis of breast carcinoma, with special reference to chemotherapy: a case report.

We report a case of small-bowel perforation due to metastatic carcinoma of the breast during chemotherapy. Partial resection of the small intestine and primary anastomosis were performed. Although the patient made a good recovery from panperitonitis, she died of the disease on the 55th postoperative day. Since perforation during chemotherapy results in an extremely poor prognosis, special caution during chemotherapy is needed for patients with possible gastrointestinal involvement with tumor.

Phase Ia study of a hypoxic cell sensitizer doranidazole (PR-350) in combination with conventional radiotherapy.

A phase Ia study of a 2-nitroimidazole nucleoside analog radiosensitizer doranidazole was conducted to evaluate its toxicity and pharmacokinetics in patients undergoing conventional external beam radiotherapy. Twenty-nine patients, aged 40-74 years, with a WHO performance status of 0-2 and with adequate organ functions, were entered in the study. Single administration of doranidazole was investigated first with 13 patients and then a course of five consecutive daily administrations was tested in 16 patients. Doranidazole was given i.v. 25 min before irradiation. Doranidazole doses of 400, 800, 1300 and 2000 mg/m2 were evaluated in the former study, and daily doses of 800, 1300 and 2000 mg/m2 were investigated in the latter study. All patients tolerated doranidazole administration. Although a transient decrease in the 24-h creatinine clearance rate was observed in five patients (one in the single administration study and four in the repeat administration study), this was not considered to be the dose-limiting toxicity. Other toxicities (hematological and gastrointestinal), which may not be related to doranidazole administration, were also mild and were not dose limiting. No neurotoxicity was observed. The average maximum concentration, area under the time-concentration curve and half-life of doranidazole in serum were 172-194 microg/ml, 502-582 microg x h/l and 4.2-4.6 h, respectively, at 2000 mg/m2. At the tested doses, administration of doranidazole was tolerable and achieved serum concentrations at which reasonable radiosensitization could be expected. A phase Ib/II study to evaluate the feasibility and efficacy of up to 30 repeat administrations seems to be warranted.

Localization of annexin V in rat normal kidney and experimental glomerulonephritis.

The localization of annexin V, a calcium binding protein, was immunochemically and immunohistologically studied in experimental rat glomerulonephritis using annexin V polyclonal antibody. Plasma and urinary annexin V levels were measured by a sandwich enzyme-linked immunosorbent assay (ELISA). Urinary annexin V level, which was correlated with urinary L-lactate dehydrogenase activity, N-acetyl-beta-D-glucosaminidase activity and protein level, increased time-dependently after the injection of nephritogenic antigen (bovine glomerular basement membrane), progressively increasing to attain a peak level at 4 weeks of 51.5 +/- 11.3 ng/h. However, plasma annexin V level showed no increase during the study period. Normal kidneys showed strong staining for annexin V in distal tubules, being particularly strong in tubules of the inner stripe of the outer medulla, but could not be detected in proximal tubules. Annexin V was seen in visceral epithelial cells. Bowman's capsule of the glomerulus, the vascular endothelium of arterioles and interlobular arteries, and vascular smooth muscle. In nephritis, the lumen of distal tubules and the luminal cell membrane were deeply stained, with leakage of annexin V being observed from tubular cells. In the present study, renal annexin V was markedly excreted into urine, and its urinary level reflected the severity of damage of renal tissue and the progression of nephritis. These changes of annexin V in the distal tubule and visceral epithelial cells may be of significance in cell injury of the kidney.

High proliferative activity is associated with dysplasia in ulcerative colitis.

PURPOSE: Ulcerative colitis is associated with an increased risk of colorectal neoplasia. Markers of proliferation are reported to be valuable in the diagnosis of dysplasia in ulcerative colitis. However, it is not known whether dysplastic change or proliferative change occurs first. Whether abnormal proliferation is present in normal-seeming mucosa in ulcerative colitis was investigated. METHODS: Eighteen cancer or high-grade dysplasia specimens and 9 low-grade dysplasia specimens from 5 patients and 51 specimens from 31 patients without neoplasia were studied. Immunostaining with anti-Ki 67 antibody was used to evaluate proliferative activity. Labeling index (in the superficial one-half of crypt) was calculated. Crypts with labeling index more than 0.3 were determined to have abnormal proliferation. RESULTS: The mean +/- standard error of the mean labeling index in specimens negative for dysplasia (0.056+/-0.004) was significantly lower than that in low-grade dysplasia specimens (0.418+/-0.024) and that in high-grade dysplasia specimens (0.503+/-0.027; P < 0.0001). In specimens negative for dysplasia, only 4 (4 cases) of 339 (1.2 percent) crypts had abnormal proliferation, whereas the ratio of crypts with abnormal proliferation was 76 percent (54/71) in low-grade dysplasia and 92.1 percent (35/38) in high-grade dysplasia. The labeling index in background mucosa was 0.139+/-0.009, which was significantly higher than that in specimens negative for dysplasia (P < 0.001). In background mucosa 15.7 percent of crypts showed abnormal proliferation. A follow-up study revealed that two of four cases developed cancer or high-grade dysplasia one and seven years after proliferative abnormality was detected in nondysplastic specimens. CONCLUSION: Ki-67 immunostaining can be an aid in the diagnosis of dysplasia. High proliferating activity in background mucosa suggests that proliferating activity change precedes dysplasia detected with hematoxylin-and-eosin staining.
