Both carcinoembryonic antigen and CA19-9 are considered as predictive markers of intestinal cancer recurrence and metastasis.In addition,CA19-9 elevation is considered as a predictive marker of connective tissue disease-related interstitial lung disease.The incidence of oxaliplatin and capecitabine-associated interstitial lung disease is low,and there is no report about CA19-9 as a predictive marker of oxaliplatin and capecitabine-associated interstitial lung disease.This paper reports a case of interstitial lung disease with CA19-9 elevation caused by oxaliplatin and capecitabine adjuvant therapy for ileocecal carcinoma.The change trend of serum carcinoembryonic antigen in this patient was consistent with tumor recurrence and metastasis,and that of serum CA19-9 was consistent with the severity of interstitial lung disease.Therefore,CA19-9 elevation after intestinal cancer surgery does not necessarily indicate the tumor recurrence and metastasis,and attention should be paid to the possibility of oxaliplatin and capecitabine-associated interstitial lung disease.

OBJECTIVE: To detect the serum level of chemokine CXC motif chemokine 10 (CXCL-10) and Krebs von den lungen-6 (KL-6) in patients with rheumatoid arthritis associated interstitial lung disease (RA-ILD), and to analyze their correlation with RA-ILD, as well as the significance in RA-ILD. METHODS: A total of 169 RA patients were enrolled in the study. According to imaging findings of with and without ILD in high-resolution computed tomography scans of chest, the subjects were divided into RA-ILD group and RA-non-ILD group. According to the inclusion and exclusion criteria, 80 patients in each of the two groups were finally selected. Two groups were matched according to the 1 ∶ 1 ratio using propensity score matching (PSM). The serum CXCL-10 and KL-6 levels were detected by enzyme-linked immunosorbent assay. The clinical features, laboratory data and medications between the two groups were compared after PSM and the correlation between serum levels and clinical parameters were analyzed. Binary Logistic regression was used to analyze the risk factors of ILD in the RA patients, and the predictive value of CXCL-10 and KL-6 in RA-ILD was evaluated. RESULTS: In this study, 49 patients with RA-ILD and 49 patients with RA-non-ILD were selected by PSM. The levels of CXCL-10 and KL-6 in the RA-ILD group [64.36 (34.01, 110.18) ng/L, 360.70 (236.35, 715.05) U/mL] were significantly higher than those in the RA-non-ILD group [29.80 (16.89, 40.55) ng/L, 210.69 (159.98, 255.50) U/mL] (all P < 0.001). The results of correlation analysis showed that the level of serum CXCL-10 was positively correlated with the Warrick score on chest CT (r=0.378, P=0.007) and negatively correlated with the percentage of forced vital capacity to the predicted value (FVC%, r=-0.338, P=0.018). And the level of KL-6 was positively correlated with rheumatoid factor (RF, r=0.296, P=0.039) and negatively correlated with FVC% (r=-0.436, P=0.002) and the percentage of diffusion capacity for carbon monoxide to the predicted value (DLCO%, r=-0.426, P=0.002). Both univariate and multivariate Logistic regression analysis showed that CXCL-10 and KL-6 were positively correlated with ILD, the values of OR were 1.035 and 1.023 in CXCL-10 and those were 1.004 and 1.005 in KL-6 respectively (P < 0.05). The ROC curves were plotted with CXCL-10 and KL-6. The area under the curve (AUC) was 0.770 and 0.752 respectively. The AUC of combined detection increased to 0.800. CONCLUSION Serum levels of CXCL-10 and KL-6 are significantly elevated in patients with RA-ILD and correlated with the severity of ILD. The combined estimate of them helps to improve the effectiveness of diagnosis.

OBJECTIVE: To investigate the clinical and immunological characteristics of anti-synthetase syndrome (ASS) patients overlap with rheumatoid arthritis (RA). METHODS: A retrospective analysis was conducted on ASS patients with arthritis who were treated at Peking University People' s Hospital. Data collected included demographic information, clinical manifestations, laboratory features, lymphocyte subsets in peripheral blood, and treatments. The patients with ASS were divided into two groups based on the presence or absence of RA for comparative analysis. RESULTS: A total of 104 ASS patients with arthritis were included, among whom 23.1% (24/104) were diagnosed with RA. The ASS with RA group had a significantly higher incidence of rapidly progressive interstitial lung disease (RP-ILD) (41.7% vs. 17.6%, P=0.032), number of tender joints [10 (7, 14) vs. 4 (0, 8), P < 0.001], number of swollen joints [4 (2, 8) vs. 2 (0, 4), P=0.012], and rate of bone erosion (47.8% vs. 2.5%, P < 0.001) compared with the non-RA group. Levels of platelets [(289.57±68.74)×10³/μL vs. (247.94±77.04)×10³/μL, P=0.022], erythrocyte sedimentation rate (ESR) [43 (19, 59) mm/h vs. 18 (10, 44) mm/h, P=0.019], and C-reactive protein (CRP) [19.20 (4.80, 55.36) mg/L vs. 5.68 (1.10, 14.96) mg/L, P=0.006] were found significantly higher in the ASS with RA group than those in non-RA group. Analysis of immune cells in peripheral blood mononuclear cell (PBMC) showed that significantly decreased proportions of CLA⁺ Treg cells [(11.12±4.10)% vs. (17.22±8.49)%, P=0.003], B cells [8.56% (4.80%, 11.90%) vs. 14.55% (8.75%, 20.29%), P=0.025], and natural killer (NK) cells [7.56% (4.65%, 13.20%) vs. 13.25% (7.46%, 19.25%), P=0.045] in the overlap group compared with non-RA group. Proportion of Naïve Th cells [(52.66±17.66)% vs. (40.76±14.96)%, P=0.033)] was significantly increased in overlap group compared with non-RA group. Overlap group had lower rate of complete clinical response than non-RA group (16.7% vs. 43.8%, P=0.031). CONCLUSION Among ASS patients with arthritis, those with RA have more severe lung and joint involvement and a lower treatment response rate, highlighting the need for early recognition and aggressive intervention.

OBJECTIVE: To summarize the clinical characteristics of 57 patients diagnosed with anti-glycyl tRNA synthetase (anti-EJ) positive antisynthetase syndrome (ASS), a subtype of anti-glycyl tRNA positive ASS, complicated by interstitial lung disease (ILD), and to investigate the factors asso-ciated with ILD recurrence. METHODS: A retrospective analysis was conducted on the clinical data of 57 anti-EJ positive ASS patientswho were treated at the First Affiliated Hospital of Nanjing Medical University from January 1, 2020 to June 30, 2024. The data collected included demographic information, clinical characteristics, laboratory test results, chest CT findings, and pulmonary function tests. The characteristics of ILD recurrence were also analyzed. RESULTS: All the 57 patients with anti-EJ positive ASS were diagnosed with ILD. The mean age at disease onset was (58.18±10.27) years, with a mean disease duration of 3.00 (2.00, 16.00) months. Among the patients, 70. 18% were female, 87.72% experienced a cough, 70. 18% had expectoration, 89.47% reported respiratory difficulties, and 14.04% developed respiratory failure. The results of pulmonary function test showed that the percentage of forced vital capacity (FVC) in the normal predicted value (FVC%), the percentage of forced expiratory volume in the first second (FEV1) in the normal predicted value (FEV1%) and the percentage of diffusion lung carbon monoxide (DLCO) in the normal predicted value (DLCO%) were 59.36±21.41, 58.34±19.46 and 58.17±27.95, respectively. The oxygenation index was (363.24±99.42) mmHg. Chest CT imaging showed that nonspecific interstitial pneumonia (NSIP) was the most common radiographic pattern. Among the 46 patients who completed a follow-up of more than 12 months, 21 cases (45.65%) showed recurrence of ILD. The average age of onset for the recurrence group was (61.38±8.63) years, while that for the non-recurrence group was (55.28±11.85) years, with a difference approaching statistical significance (P=0.056). Further analysis showed that the ESR (erythrocyte sedimentation rate) level was significantly higher in the recurrence group than in the non-recurrence group [(50.48±29.64) mm/h vs. 30.28±23.97) mm/h, P=0.025], and the IgM (immune globulin M) level was also significantly higher in the recurrence group (P=0.042). Moreover, the CD8+T proportion was significantly higher in the recurrence group than in the non-recurrence group (25.48±11.81 vs. 18.59± 8.53, P=0.027). Despite the fact that the recurrence group had a higher baseline age, higher ESR, IgM, and CD8+T proportion, multivariate binary logistic regression analysis showed that these indicators were not independent risk factors for ILD recurrence. CONCLUSION ILD is the most common clinical manifestation in patients with anti-EJ positive ASS, with a significant impact on pulmonary function. Although the patients responded well to a combination of glucocorticoid and immunosuppressive therapies, the recurrence rate remains high, particularly in those with increased sputum production, and elevated ESR. Close monitoring and early intervention for high-risk patients are essential to improving long-term outcomes.

BACKGROUND: Handgrip strength is a simple, convenient and economic tool measuring the muscle strength. A few studies investigated the relationship between diabetes and handgrip strength but the results are conflicting. This study investigated the association of handgrip strength with diabetes among the adult Koreans. METHODS: This cross-sectional study analyzed data from participants aged 20 years or more (n=8,082) who measured height, weight, handgrip strength and fasting blood glucose in the 2014–2015 Korea National Health and Nutrition Examination Survey. Relative handgrip strength (RHGS) was defined as the sum of the greatest handgrip strengths in both hands divided by body mass index. To investigate the association of diabetes with handgrip strength, complex sample multivariate logistic regression analyses were done after adjusting for socioeconomic (age, sex, education), lifestyle (smoking, alcohol drinking, physical activity, obesity) and comorbid (chronic obstructive pulmonary disease, stroke, coronary artery disease, arthritis) variables. Stratified analysis were done according to socioeconomic and lifestyle variables. RESULTS: The prevalence of diabetes was 8.3% (standard error, 0.4). After adjusting for socioeconomic, lifestyle, and comorbid variables, the risk of diabetes increased according to the decrease in sex-specific quartile of RHGS (P(trend)<0.001). Individuals with lower RHGS (per 1 standard deviation decrease) had higher odds of diabetes (adjusted odds ratio, 1.6; 95% confidence interval, 1.3–2.0). Furthermore, lower RHGS was associated with higher odds for diabetes throughout the strata of socioeconomic and lifestyle variables. CONCLUSIONS: This population-based, nationally representative study suggests that lower RHGS is associated with the increased risk of diabetes regardless of socioeconomic and lifestyle variables.

BACKGROUND: It is unclear whether impaired pulmonary function serves as a risk factor for decreased renal function. This study investigated the association between the forced vital capacity (FVC) and chronic kidney disease (CKD) in middle-aged and elderly men.METHODS: We investigated the association between FVC and CKD in 412 Korean men aged ≥50 years, without diabetes, who have not received treatment for chronic lung disease. CKD was defined based on evidence of renal tissue damage or reduced renal function indicated by estimated glomerular filtration rate < 60 mL/min/1.73 m² or proteinuria level ≥1+. We assessed the association between FVC and CKD using multivariate logistic regression analysis after adjusting for confounders.RESULTS: The overall prevalence of CKD was 29.2% in the study population. Multivariate logistic regression analysis showed that the odds ratio with a 95% confidence interval for CKD was 0.96 (0.92–0.99) with a 1% increment in FVC after adjusting for age, body mass index, smoking status, alcohol intake, regular exercise, systolic and diastolic blood pressures, fasting plasma glucose, triglyceride, and high-density lipoprotein-cholesterol levels, as well as antihypertensive and antidyslipidemic medications.CONCLUSION: We observed that FVC was independently and inversely associated with CKD. This finding suggests that careful monitoring of renal function is necessary to evaluate possible kidney dysfunction in patients with decreased FVC.

OBJECTIVE: To evaluate the value of anti-carbamylated protein (CarP) antibody in the diagnosis of rheumatoid arthritis-associated intersitial lung diseas (RA-ILD). METHODS: Clinical and laboratory data and serum samples of patients with RA between December 2017 and June 2019 in Department of Rheumatology, General Hospital of Ningxia Medical University were collected. The patients were subclassified as RA-ILD and RA-without ILD based on computed tomography scans of the chest, Enzyme 1inked immunosorbent assay (ELISA) was used to assess anti-CarP antibody in the serum of each group. The occurrence of ILD and other laboratory indexes were analyzed. Comparison of measurement data between the 2 groups was performed by two independent sample t-test or Mann-Whitney U nonparametric test, while the count data were compared by Chi square test; Receiver operating characteristic curve (ROC) was drawn to determine the cut-off value of anti-CarP antibody to RA-ILD diagnosis and to analyze its diagnostic efficacy. RESULTS: The anti-CarP antibody level in the RA-ILD group was 21.14 (12.29, 29.75), which was significantly higher than that in the RA-without ILD group 11.6 (6.66, 19.05) (P=0.000). The difference was statistically significant (P<0.05). The positive rate of anti-CarP antibody in RA-ILD group (53%) was significantly higher than that in RA-without ILD group (16%) (P<0.05); There was no significant differences in the levels of rheumatoid factor (RF) and anti-cyclic citrullinated peptide (CCP) between the two groups (P>0.05). The age and disease activity score (DAS28) in the RA-ILD group were significantly higher than those in the RA-withhout ILD group (P<0.05). The proportion of men and smoking in the RA-ILD group was higher than that in the RA-without ILD group, but the difference was not statistically significant. The ROC curve showed that the anti-CarP antibody had a cut off value of 20.56 U/mL, with the sensitivity of 53.50%, and specificity of 84.20%, the area under the ROC curve were 0.76. Spearman correlation analysis showed that rheumatoid factor (RF) and age were positively correlated with anti-CarP antibody (r=0.172, P=0.043; r=0.200, P=0.006). Anti-CarP antibody level was not associated with the DAS28 score, erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), anti-CCP antibody, swollen joint count, and tender joint count (P>0.05). CONCLUSION The anti-CarP antibody level in RA-ILD patients is higher than that in RA-without ILD, suggesting that anti-CarP antibody may have a role in the development of RA-ILD.

We need to understand the outcomes into adulthood for survivors born either extremely low birthweight (ELBW; < 1,000 g) or extremely preterm (EP; < 28 weeks' gestational age), particularly their blood pressure and cardiovascular metabolic status,respiratory function, growth, psychological and mental health performance, and functional outcomes. Blood pressure is higher in late adolescence and early adulthood in ELBW/EP survivors compared with controls. In some studies, expreterm survivors have higher insulin and blood lipid concentrations than controls, which may also increase their risk for later cardiovascular disease. ELBW/EP survivors have more expiratory airflow obstruction than do controls. Those who had bronchopulmonary dysplasia (BPD) in the newborn period have even worse lung function than those who did not have BPD. As a group, they are unlikely to achieve their full lung growth potential, which means that more of them are likely to develop chronic obstructive airway disease in later life. Although they are smaller than term born controls, their weight gradually rises and ultimately reaches a mean z-score close to zero in late adolescence, and they ultimately attain a height z-score close to their mid-parental height z-score. On average, ex-preterm survivors have intelligence quotient (IQ) scores and performance on tests of academic achievement approximately 2/3 SD lower than do controls, and they also perform less well on tests of attention and executive function. They have similar high rates of anxiety and depression symptoms in late adolescence as do controls. They are, however, over-represented in population registries for rarer disorders such as schizophrenia and Autism Spectrum Disorder. In cohort studies, ex-preterm survivors mostly report good quality of life and participation in daily activities, and they report good levels of self-esteem. In population studies, they require higher levels of economic assistance, such as disability pensions, they do not achieve education levels as high as controls, fewer are married, and their rates of reproduction are lower, at least in early adulthood. Survivors born ELBW/EP will present more and more to health carers in adulthood, as they survive in larger numbers.

PURPOSE: Interface pressure is a factor that contributes to the occurrence of pressure injuries. This study aimed to investigate interface pressure at common sites of pressure injury (occipital, gluteal and peritrochanteric areas), to explore the relationships among risk factors, skin condition and interface pressure, and to identify risk factors influencing interface pressure. METHODS: A total of 100 patients admitted to the intensive care unit were enrolled at a tertiary teaching hospital in Korea. Interface pressure was recorded by a scanning aid device (PalmQ). Patient data regarding age, pulmonary disease, Braden Scale score, body mass index, serum albumin, hemoglobin, mean blood pressure, body temperature, and oxygen saturation were included as risk factors. Data collected from July to September 2016 were analyzed using binary logistic regression. RESULTS: The mean interface pressure of the occipital, gluteal, and right and left peritrochanteric areas were 37.96 (±14.90), 41.15 (±16.04), 53.44 (±24.67), and 54.33 (±22.80) mmHg, respectively. Predictive factors for pressure injuries in the occipital area were age ≥70 years (OR 3.45, 95% confidence interval [CI]: 1.19~9.98), serum albumin deficit (OR 2.88, 95% CI: 1.00~8.26) and body temperature ≥36.5℃ (OR 3.12, 95% CI: 1.17~8.17); age ≥70 years (OR 2.81, 95% CI: 1.10~7.15) in the right peritrochanteric area; and body temperature ≥36.5℃ (OR 2.86, 95% CI: 1.17~6.98) in the left peritrochanteric area. CONCLUSION: Our findings suggest that old age, hypoalbuminemia, and high body temperature may be contributory factors to increasing interface pressure; therefore, careful assessment and nursing care of these patients are needed to prevent pressure injury. Further studies are needed to establish cutoff values of interface pressure for patients with pressure ulcers.
