Prevalence and prognosis of cachexia according to the Asian Working Group for Cachexia criteria in sarcopenic dysphagia: A retrospective cohort study.

OBJECTIVE: The aim to examine the prevalence and prognosis of cachexia according to the Asian Working Group for Cachexia (AWGC) criteria in patients with sarcopenic dysphagia. METHODS: A retrospective cohort study was conducted with 271 patients diagnosed with sarcopenic dysphagia out of 467 patients enrolled in the Japanese sarcopenic dysphagia database. Cachexia was diagnosed by the AWGC criteria. The AWGC criteria includes chronic diseases, either or both weight loss (2% or more over 3-6 mo) or low BMI (<21 kg/m2), and at least one of the following: anorexia, decreased grip strength (<28 kg in men and <18 kg in women), or elevated C-reactive protein levels (>0.5 mg/dL). Outcomes were death, swallowing function as assessed by the Food Intake LEVEL Scale (FILS), and activities of daily living as assessed by the Barthel Index (BI) at follow-up. RESULTS: The mean age was 84 (±8) y; 152 (56%) were female, and 97 (36%) had cachexia. In univariate analysis, death was significantly more common in the cachexia group (15% versus 2%, P ≤ 0.001). Logistic regression analysis showed that cachexia was independently associated with death (odds ratio: 3.557, 95% confidence interval: 1.010, 12.529). No significant differences were found in the presence or absence of cachexia in the FILS (7 versus 8, P = 0.849) and BI (55 versus 52.5, P = 0.892). CONCLUSIONS: Cachexia was found in 36% of patients with sarcopenic dysphagia, and death was significantly higher in cachexia.

Rehabilitation nutrition for individuals with frailty, disability, sarcopenic dysphagia, or sarcopenic respiratory disability.

PURPOSE OF REVIEW: We describe the recent advances in rehabilitation nutrition, which is especially important for disabled or frail older individuals. RECENT FINDINGS: Recent evidence pertaining to rehabilitation nutrition conducted in rehabilitation wards and acute care hospitals has been accumulating. The combination of rehabilitation nutrition and rehabilitation pharmacotherapy is important for eliciting higher functions. The 2020 update of the clinical practice guidelines for rehabilitation nutrition provides a weak recommendation for enhanced nutritional care for patients with cerebrovascular disease, hip fracture, cancer, or acute illness who are undergoing rehabilitation. Rehabilitation nutritional care process and the International Classification of Functioning, Disability and Health-Dietetics are used to implement high-quality rehabilitation nutrition. Aggressive nutrition therapy incorporates the daily energy expenditure plus daily energy accumulation to increase body weight and muscle mass. Preventing and treating sarcopenic dysphagia should include iatrogenic sarcopenia prevention and aggressive nutrition therapy. The diagnosis criteria for respiratory sarcopenia and sarcopenic respiratory disability have been established. SUMMARY: The International Association of Rehabilitation Nutrition and Total Nutrition Therapy Rehabilitation program may contribute to international expansion of rehabilitation nutrition. Improving evidence-practice gaps in rehabilitation nutrition and increasing national health insurance coverage of aggressive nutrition therapy and rehabilitation nutrition teams are warranted.

A Case of Long-Term Survival after Checkpoint Inhibitor Pneumonitis in a Patient with Squamous Cell Lung Cancer.

The management of grade 1 checkpoint inhibitor pneumonitis (CIP) is to withhold immune checkpoint inhibitors; however, the natural history of this condition is unknown. We herein report the case of a woman with squamous cell lung cancer who was a long-term survivor after CIP. After 4 rounds of treatment with nivolumab, a chest CT revealed a reticular pattern and ground-glass attenuation with shrinkage of the primary nodule. Nivolumab treatment was withheld without the administration of steroids. Although she remained asymptomatic, subsequent images revealed an increasing interstitial shadow until 2 months after the stop of nivolumab treatment. Thereafter, the interstitial shadow began to improve spontaneously without steroid treatment. Moreover, although the patient has not received additional therapy, disease control of lung cancer has been obtained within a follow-up period of more than 3 years. Although the exacerbation of CIP may appear on images for several months, asymptomatic cases can be followed without the administration of steroids. If the tumor had already responded prior to the onset of CIP, a favorable long-term prognosis can be expected.

Recurrent Cerebral Infarction Due to Benign Uterine Myoma.

The hypercoagulable state in patients with cancer has been shown to be closely associated with ischemic stroke. However, it is unlikely that benign tumors are related to stroke. The development of benign uterine tumors is common in middle-aged women. Previous studies have shown cases of ischemic stroke with benign uterine tumor, but the causal relationship between these 2 remain unknown. We report a case of recurrent ischemic stroke in a middle-aged woman who had a benign uterine tumor. After excision, there was no recurrence for 2 years. Microemboli detection, clinical course and histological findings support a relationship between uterine tumor and ischemic stroke.

Associations of Mitral and Aortic Valve Calcifications with Complex Aortic Atheroma in Patients with Embolic Stroke of Undetermined Source.

BACKGROUND: This study investigated the associations of mitral and aortic valve calcification with complex aortic atheroma among patients with embolic stroke of undetermined source. METHODS: We included 52 consecutive patients (mean age 58.1 years; 75.0% male) with embolic stroke of undetermined source. Mitral annular calcification, aortic annular calcification, and aortic valve sclerosis were assessed by transthoracic echocardiography. Complex aortic atheroma was assessed by transesophageal echocardiography and was defined as plaque protruding greater than or equal to 4 mm into the lumen or with ulcerated or mobile components. RESULTS: Ten patients (19.2%) had complex aortic atheroma. Patients with and without complex aortic atheroma showed significant differences in terms of hypertension (80.0% versus 38.1%, P = .017), dyslipidemia (90.0% versus 31.0%, P <.01), chronic kidney disease (60.0% versus 14.3%, P <.01), previous coronary artery disease (30.0% versus 4.8%, P = .013), prior stroke (40.0% versus 7.1%, P <.01), left atrial dimension (4.0 cm versus 3.6 cm, P = .023), aortic valve sclerosis (80.0% versus 26.2%, P <.01), aortic valve calcification (aortic annular calcification or aortic valve sclerosis) (80.0% versus 26.0%, P <.01), and left-sided valve calcification (mitral annular calcification or aortic annular calcification or aortic valve sclerosis) (80.0% versus 28.6%, P <.01). In multivariate analysis, left-sided valve calcification was independently associated with complex aortic atheroma (odds ratio 4.1, 95% confidence interval 1.3-26.1, P = .049). CONCLUSIONS: Mitral or aortic valve calcification detected by transthoracic echocardiography can be a useful marker for predicting complex aortic atheroma in patients with embolic stroke of undetermined source.

Functional Outcomes of Decompressive Craniectomy in Patients with Malignant Middle Cerebral Artery Infarction and Their Association with Preoperative Thalamus Deformation: An Analysis of 12 Patients.

Objective Decompressive craniectomy (DC) in patients with malignant middle cerebral artery (MCA) infarction is known to decrease the mortality rate. However, the functional outcomes (communication and oral intake) of this procedure remain unclear. Most patients with malignant MCA infarction exhibit a loss of consciousness, which may be principally governed by the thalamus. We herein investigated the functional outcomes of DC at 90 days after the onset of malignant MCA infarction and their association with preoperative thalamus deformation, which can occur due to pressure and edema. Methods Twelve of 2,692 patients with acute cerebral infarction were diagnosed with malignant MCA infarction and underwent DC. We evaluated preoperative thalamus damage using brain computed tomography and its association with communication and oral intake abilities and the modified Rankin Scale (mRS) and Barthel index scores at 90 days after stroke onset. Results The mRS score at 90 days was 0-4 in five patients. Seven patients could communicate immediately after surgery, while five could do so by 90 days. Five patients were able to resume the oral intake of food at 90 days. All patients with preoperative thalamus deformation showed a poor recovery, while those with absent or slight preoperative thalamus deformation showed a good recovery. Conclusion Patients with preoperative thalamus deformation caused by pressure and edema show a poor oral intake and communication abilities after DC, suggesting that preoperative thalamus deformation is a predictor of poor functional outcomes after DC in patients with malignant MCA infarction.

Advanced stage of chronic kidney disease is risk of poor treatment outcome for smear-positive pulmonary tuberculosis.

Chronic kidney disease (CKD) is an increased risk for the development of active tuberculosis, but few studies have analyzed the treatment outcome of pulmonary tuberculosis among CKD patients. A retrospective cohort study was conducted at Chiba-East Hospital in Chiba, Japan. Our study estimated the treatment outcomes in smear-positive pulmonary tuberculosis in relation to CKD and its stages. Total subjects were 759 patients (12-99 years) hospitalized between 2007 and 2012. Patients suffering from multi-drug-resistant tuberculosis were excluded. Patients with CKD were 19.3% aged <65 years (n = 384), and 49.6% aged ≥ 65 years, respectively (P < 0.001). Successful treatment was 52.7% in CKD (n = 260) and 67.3% in non-CKD (n = 499) (P < 0.001). Death was 25.4% in CKD and 12.4% in non-CKD (P < 0.001). Treatment outcome was especially poor in patients with low estimated glomerular filtration rate (eGFR) of <30 ml/min/1.73 m(2), as successful treatment was 20.0%, and death was 50.0%, significantly lower than in other CKD and non-CKD patients. After multivariate logistic regression analysis, eGFR<30 ml/min/1.73 m(2) was an independent factor affecting successful treatment and death, and its adjusted odds ratios (aOR) were 0.20 (95% confidence interval (CI) 0.07-0.50) and 2.99 (95%CI 1.20-7.51), respectively. Other factors affecting successful treatment were serum albumin <3.0 mg/dl, steroid therapy for underlying disease and cardiovascular disease, with aOR (95%CI) of 0.28 (0.20-0.39), 0.32 (0.16-0.63) and 0.49 (0.28-0.86), respectively. Several factors were associated with poor treatment outcome of smear-positive pulmonary tuberculosis. Advanced stage of CKD with eGFR of <30 ml/min/1.73 m(2) was a risk factor for poor treatment outcome.

Brain natriuretic peptide in acute ischemic stroke.

Elevated serum brain natriuretic peptide (BNP) levels are associated with cardioembolic stroke mainly because of atrial fibrillation (AF). However, the mechanisms of increased serum BNP levels are hitherto unclear. We aimed to identify the factors associated with increased BNP levels in patients with acute ischemic stroke. We measured serum BNP levels in consecutive patients aged 18 years or older. Stroke subtypes were classified using the Trial of ORG 10172 in Acute Stroke Treatment criteria. Categorical variables included age, sex, smoking status, alcohol consumption status, hypertension, diabetes mellitus, dyslipidemia, coronary artery disease (CAD), AF, antiplatelet therapy, and anticoagulant therapy. Continuous variables included hemoglobin, creatinine (Cr), ß-thromboglobulin, platelet factor 4, thrombin-antithrombin complex, and d-dimer levels. We further determined the relationship between serum BNP and intima-media thickness, left ventricular ejection fraction, size of infarction, National Institutes of Health Stroke Scale score on admission, and modified Rankin Scale (mRS) score at discharge. Of the 231 patients (mean age, 71 ± 12 years) with acute ischemic stroke (AIS), 36% were women. Serum BNP levels significantly correlated with CAD, AF, Cr, mRS, and cardioembolism (CE) (Dunnett method, P = .004). BNP levels were significantly higher in patients with larger infarcts, higher mRS scores, and higher CHADS2 scores. The levels were higher in patients with larger infarcts, higher mRS scores at discharge, and higher CHADS2 scores among AF patients.

Risk of acute exacerbation of interstitial pneumonia after pulmonary resection for lung cancer in patients with idiopathic pulmonary fibrosis based on preoperative high-resolution computed tomography.

PURPOSE: In patients with lung cancer accompanied by idiopathic pulmonary fibrosis (IPF), acute exacerbation of the IPF often occurs after pulmonary resection; however, few studies have been done to identify its preexisting risk factors. METHODS: We analyzed the high-resolution computed tomography (HRCT) findings of IPF to identify the radiological characteristics of IPF susceptible to acute exacerbation after lung cancer surgery. We reviewed retrospectively 28 lung cancer patients with IPF who underwent pulmonary resection. Clinical data, respiratory function, HRCT findings, and historical features were compared between the acute exacerbation (n = 9) and nonexacerbation (n = 19) groups. The classification of radiological findings of IPF on HRCT was done using a scoring system of seven factors related to the interstitial shadow, including fibrosis, ground-glass opacity, and low-attenuation area. RESULTS: There were no significant differences in clinical background, respiratory function, composite physiologic index, or pathological features between the groups; however, the degree of fibrosis on preoperative HRCT was significantly higher in the exacerbation group (P < 0.003). The fibrosis score was higher on the opposite side to the lung cancer in the exacerbation group (P < 0.05). CONCLUSION: Although it is difficult to predict postoperative acute IPF exacerbation, the degree and laterality of co-existing fibrosis seem to be predictors.

Stomatal density is controlled by a mesophyll-derived signaling molecule.

Stomata are composed of a pair of guard cells and a pore between them, and their density and positions are regulated by developmental and environmental signals. In a screen in which we overexpressed many genes coding for putative secretory proteins one by one in Arabidopsis, we identified a gene named STOMAGEN, which increases stomatal density when overexpressed. The STOMAGEN gene encodes a small peptide with a putative secretory signal sequence at its N-terminus and is expressed preferentially in mesophyll cells. This peptide belongs to the EPIDERMAL PATTERNING FACTOR (EPF) family of the cysteine-rich peptides superfamily. The mature form was a 45-amino-acid peptide (stomagen) with three intramolecular disulfide bonds. Stomagen treatment at very low concentrations, as low as 10 nM, increased the stomatal density of wild-type Arabidopsis plants. We propose that stomagen is a mesophyll-to-epidermis signaling molecule that positively regulates stomatal density. We also suggest that stomagen increases stomatal density by competing with negative regulators EPF1 and EPF2 for the receptor-like protein TOO MANY MOUTHS.

[A hospital based study on evaluation of causes of death in 52 patients with pulmonary tuberculosis].

PURPOSE: To examine the clinical problems of died cases with pulmonary tuberculosis. METHODS: Clinical findings of 52 patients with active pulmonary tuberculosis, who had died in our hospital between April 2005 to March 2007, were analyzed. RESULTS: Mean age was 72.3 10.6 years old, 9 cases (17.3 %) were relapsed, and 35 cases (67.3%) had cavity on the chest X-ray. 34 cases (65.4%) were PS4 and none was PS0 or PS1 on admission. Complications were malignancy in 11 cases, diabetes mellitus in 10 cases, and respiratory diseases in 6 cases. 15 cases (28.8%) were treated with drugs including INH, RFP and PZA, 14 cases (26.9%) with drugs including INH and RFP, 16 cases (30.8%) with the other drugs, and 7 cases (13.5%) were not able to be administered any drug. 35 cases (67.3%) died of tuberculosis and 17 cases (32.7%) died of non-tuberculous conditions. CONCLUSION: Many died cases were under very poor general condition, needed frequent care, had many kind of complications and had difficulty with standard treatment on admission. Tuberculous death were observed highly, but death by complications were observed in many cases. It is necessary to control complications and enlighten society and docters about importance of early diagnosis and treatment of tuberculosis continuously.

[A case of pericostal tuberculosis occurred in a long period after thoracoplasty].

A 79-year-old man with past history of thoracoplasty due to pulmonary tuberculosis visited a general clinic complaining of left back pain and left axillary tumor. As the pus of tumor aspirated was positive for PCR-TB, the patient was diagnosed as pericostal tuberculosis and introduced to our hospital. At first, the operation was considered, but the patient had high risk for the operation because he was old and low body weight and the lesion of tuberculosis in his thorax was very extensive. Anti-tuberculous drugs were administrated and exclusion of pus by needle aspiration was repeated. After starting the treatment, the size of tumor had reduced guradually. Pericostal tuberculosis should be taken into consideration in case of pericostal mass with past history of tuberculosis, and the method of treatment should be decided with considering patient's condition.

Chronic obstructive pulmonary disease and interstitial lung disease in patients with lung cancer.

BACKGROUND AND OBJECTIVE: Although lung cancer is frequently accompanied by COPD and interstitial lung disease (ILD), the precise coincidence of these diseases with lung cancer is not well understood. The objectives of this study were to determine the prevalence of abnormal CT and spirometric findings suggestive of COPD or ILD in a population of patients with untreated lung cancer, and to estimate the lung cancer risk in this population. METHODS: The study population consisted of 256 patients with untreated lung cancer and 947 subjects participating in a CT screening programme for lung cancer. Semi-quantitative analysis of low attenuation area (LAA), fibrosis and ground glass attenuation (GGA) on CT was performed by scoring. Gender- and age-matched subpopulations, with stratification by smoking status, were compared using the Mantel-Haenszel projection method. RESULTS: Inter-observer consistency was excellent for LAA, but not as good for fibrosis or GGA scores. Pooled odds ratios for lung cancer risk using LAA, fibrosis, GGA scores and reduced FEV(1)/FVC and %VC were 3.63, 5.10, 2.71, 7.17 and 4.73, respectively (P < 0.0001 for all parameters). Multivariate regression analyses confirmed these results. CONCLUSION: Abnormal CT and spirometric parameters suggestive of COPD and ILD were strong risk factors for lung cancer, even after adjusting for gender, age and smoking status.

Lung cancer screening--comparison of computed tomography and X-ray.

Recent studies on lung cancer screening with CT disclosed a discrepancy between its efficiency in detecting early lung cancer and a lack of proof for decreasing mortality from lung cancer. The present study, in a city in Japan where an X-ray screening program is provided, bi-annual CT screening was performed for X-ray screening negative subjects for 4 years. Ten patients with lung cancer were detected among 22,720 person-year subjects (0.044%) through the X-ray screening. Among the X-ray screening-negative subjects, 3305 subjects participated in a CT screening program resulting in the detection of 15 patients with lung cancer (0.454%). All 15 cases detected by CT screening and 5 of the 10 cases detected by X-ray screening were at stage IA. In respect of gender, histological type and CT findings, patients detected by CT screening had a better prognostic profile than those detected by X-ray screening. Survival was significantly better in the former than the latter, both in its entirety comparison and in a comparison limited to patients who underwent surgery. In conclusion, CT screening might have the potential to detect lung cancer with good prognostic factors not limited to early detection. Sufficiently long follow-up time, therefore, would be required to evaluate the efficacy for decreasing lung cancer mortality with CT screening.
