Combining a Frailty Index Based on Laboratory Data and Pneumonia Severity Assessments to Predict In-Hospital Outcomes in Older Adults with Community-Acquired Pneumonia.

OBJECTIVES: Due to the increased morbidity, mortality, and cost of community-acquired pneumonia (CAP) in older people, strategies directed at improving disease evaluation and prevention are imperative. We independently compared the 30-day in-hospital mortality prediction ability of a frailty index based on laboratory data (FI-Lab) with that of the CURB-65 and the Pneumonia Severity Index (PSI) and then proposed combining them to further improve prediction efficiency. DESIGN: Retrospective cohort study. SETTING AND PARTICIPANTS: Patients aged ≥ 65 years (n = 2039) with CAP who were admitted to Jiangsu Provincial People's Hospital of Nanjing Medical University and Jiangsu Provincial Hospital of Chinese Medicine from January 2019 to June 2022. MEASURES: The 29-item FI-Lab, PSI and, CURB-65 were administered at admission. We defined frailty by the cut-off value of the FI-Lab score (> 0.43). Multivariable logistic regression analysis, together with the calculation of the area under the receiver operating characteristic curve (ROC-AUC), was conducted to identify stratified risks and relationships between the three indices and 30-day mortality. Participants were divided into the following three groups based on age: 65-74 years, 75-84 years, and ≥ 85 years. Hazard ratios (HRs) and 95% confidence intervals (CIs) for mortality due to frailty were calculated. RESULTS: A total of 495 participants ranging from 65 to 100 years of age were ultimately included and divided into age groups (65-74 years, n = 190, 38.4%; 75-84 years, n = 183, 37.0%; ≥ 85 years, n = 122, 24.6%). A total of 142 (28.7%) of the 495 patients were defined as having frailty. All three scores tested in this study were significantly associated with 30-day mortality in the total sample. The ORs were as follows: 1.06 (95% CI: 1.03-1.09, P < 0.001) and 2.33 (95% CI: 1.26-4.31, P = 0.007) for the FI-Lab when the score was treated as a continuous and categorical variable, respectively; 1.04 (95% CI: 1.02-1.05, P < 0.001) for the PSI; and 3.70 (95% CI: 2.48-5.50, P < 0.001) for the CURB-65. In the total sample, the ROC-AUCs were 0.783 (95% CI: 0.744-0.819) for the FI-Lab, 0.812 (95% CI: 0.775-0.845) for the PSI, and 0.799 (95% CI: 0.761-0.834) for the CURB-65 (P < 0.001). The ROC-AUC slightly improved when the FI-Lab was added to the PSI (AUC 0.850, 95% CI: 0.809-0.892, P = 0.031) and to the CURB-65 (AUC 0.839, 95% CI: 0.794-0.885, P = 0.002). Older patients with frailty showed a higher risk of in-hospital mortality, with an HR of 2.25 (95% CI: 1.14-3.58, P < 0.001). CONCLUSION AND IMPLICATIONS: The FI-Lab seems to generate simple and readily available data, suggesting that it could be a useful complement to the CURB-65 and the PSI as effective predictors of 30-day mortality due to CAP in older populations.

[To analyse the histopathological results of patients with HPV16/18 positive and colposcopic suspicious lesions].

Objective: To explore the value of histopathologic diagnosis after colposcopy for high-risk HPV16/18 positive patients with negative cytology or atypical squamous cells of undetermined significance (ASCUS) for early screening of cervical lesions. Methods: A retrospective study of cervical histopathologic diagnosis in the HPV16/18 positive patients received colposcopy evaluation before got the histology was carried out between January 2014 and January 2016. The cytology of the patients should be negative or ASCUS. A total of 337 patients with age from 21 to 65 years old were enrolled, including 214 patients with negative cytology, and 123 patients with ASCUS. Results: (1) The results of pathology were as follows: 63 (18.7%) cases inflammation, 89 (26.4%) cases cervical intraepithelial neoplasia (CIN)Ⅰ, 182 (54.0%) cases CINⅡ-Ⅲ and adenocarcinoma in situ (AIS), and 3 (0.9%) cases minimal invasive cancer (stageⅠa1). The incidence of CINⅡ and above cervical lesions was higher in the patients with ASCUS (71.5%, 88/123) than that in the patients with negative cytology (45.3%, 97/214; χ(2)=24.876, P<0.01), and it was higher in the patients with HPV16 positive (64.4%, 150/233) than that in the patients with HPV18 positive (30.3%, 27/89; χ(2)=31.388, P<0.01). There was statistically significant difference among the different age group in which the patients of 20-29 years old was 69.3% (52/75), 30-39 years old was 55.1% (75/136), 40-49 years old was 44.8% (30/67) and 50 years old and above was 47.5% (28/59; χ(2)=16.512, P=0.032). (2) Among the patients with negative cytology, the incidence of CINⅡ and above cervical lesions in the patients with HPV16 positive was higher than that in the patients with HPV18 positive [54.8% (80/146) vs 26.0% (20/77) ; χ(2)=16.930, P<0.01]. The incidence was also higher in the patients with HPV16 positive than that in the patients with HPV18 positive [76.5% (78/102) vs 55.6% (15/27) ; χ(2)=4.642, P=0.031] among the patients with ASCUS. (3) Compared to the patients diagnosed inflammation or CINⅠ, the patients diagnosed CINⅡ and above cervical lesions had higher infection rate of HPV16, lower infection rate of HPV18, higher incidence of ASCUS, and smaller parities (all P<0.05). A multifactor analysis was carried out, the results showed that HPV16 positive and ASCUS might be independent risk factors to predict the incidence of CINⅡ and above cervical lesions (P<0.01) . Conclusions: The incidence of cervical precancerous lesions is high in the women with HPV16/18 infection. Patients with HPV16 infection are more likely to have the CINⅡ and above cervical lesions than patients with HPV18 infection. Patients with HPV16/18 infection are suggested to be directly transferred to clinic of colposcopy, and then getting the histology selectively, which would be help to early detection of the cervical precancerous lesions.

[Analysis of the effects on menopausal symptoms, quality of Life, and cardiovascular risk factors of five different therapy in women at early stage of menopause].

OBJECTIVE: To explore the effects of five different therapy in women at early stage of menopause on menopausal symptoms, quality of Life and cardiovascular risk factors. METHODS: A total of 140 women at early stage of menopause were randomly divided into five groups. Thirty women took Conjugated estrogen and medroxyprogesterone acetate(CEE+ MPA) sequential therapy, 27 women took estradiol valerate and medroxyprogesterone acetate(E2V+ MPA) sequential therapy, 26 women took estradiol valerate and Progesterone Soft Capsules(E2V+ P) sequential therapy, 30 women took Kuntai capsule, and 27 took Cohosh extract.Patients in the Menopausal Hormone Therapy(MHT) groups took twelve cycles of treatment course, in the botanical drug and Chinese patent drug groups took twelve months. The KMI scalewas used to measure the level of menopausal symptoms. MENQOL scale was used to measure the health-related quality of life before and at the 3(rd) month, 6(th) month, 9(rd) month and 12(th) month after the treatment. Some serological indicators which related to cardiovascular risk factors were collected before and at the 12(th) month after the treatment. RESULTS: (1) KMI: It showed that the KMI in five groups after the treatment were significantly different(P<0.01), the group of CEE+ MPA decreased most(13±1). The KMI after the treatment were all significantly lower than that before. (2)MENQOL: It showed that the MENQOL in five groups were significantly different(P<0.01), the group of CEE+ MPA decreased most (84±3), then the group of Kuntai(85±3). The MENQOL after the treatment were all significantly lower than that before. (3)The change of cardiovascular risk factors: it showed that the serological indicators FBGin group of CEE+ MPA after the treatment were significantly lower than that before(P<0.05); the TC, LDL, FI in group of E2V+ MPA after the treatment were significantly lower than that before(P<0.05); the FBG, FI in group of E2V+ P after the treatment were significantly lower than that before(P<0.05). CONCLUSION: The MHT, botanical drug and Chinese patent drug have great clinical curative effects in treating perimenopause syndrome, improving the health-related quality of life and decreasing risk factors of cardiovascular disease.With rare adverse events and good clinical medication safety, they could be widely applied to clinic to women at early stage of menopause who was suffering menopausal symptoms.

Increased plasma dipeptidyl peptidase-4 activities are associated with high prevalence of subclinical atherosclerosis in Chinese patients with newly diagnosed type 2 diabetes: a cross-sectional study.

OBJECTIVE: Hyperglycemia, insulin resistance, dislipidemia, oxidative stress and inflammation are well-documented risk factors for subclinical atherosclerosis. Dipeptidyl peptidase-4(DPP4) is a newly identified adipokine related to these risk factors. Hence, we aimed to investigate the association between plasma DPP4 activities and subclinical atherosclerosis in type 2 diabetes. METHODS: A total of 985 newly diagnosed type 2 diabetic subjects were studied. Plasma DPP4 activity, mannose 6-phosphate receptor (M6P-R), oxidative stress parameters, inflammatory markers and common carotid artery Intima-Media Thickness (c-IMT) were measured in all participants. RESULTS: Participants in the highest quartile of DPP4 activity had higher HbA1c, homeostatic model assessment of insulin resistance(HOMA-IR), triglyceride, low-density lipoprotein cholesterol(LDL-C), oxidized LDL, nitrotyrosine, 8-iso-PGF2a, interleukin-6 (IL-6), high-sensitivity C-reactive protein (hs-CRP), M6P-R, c-IMT compared with participants in the lowest quartile (all P < 0.001). DPP4 activities were associated positively with HbA1c, HOMA-IR, triglyceride, LDL-C, oxidized LDL, nitrotyrosine, 8-iso-PGF2a, IL-6, hs-CRP, M6P-R and c-IMT (all P < 0.05). The ORs for insulin resistance, dislipidemia, oxidative stress and inflammation were higher with increasing DPP4 quartiles (P < 0.001 for trend). In the highest DPP4 quartile, subclinical atherosclerosis risk was significantly higher (OR 4.97; 95% CI 3.03-8.17) than in the lowest quartile. This association remained strong (2.17; 1.21-3.89) after further controlling for HbA1c, HOMA-IR, triglyceride, oxidized LDL, nitrotyrosine, and IL-6. CONCLUSIONS: This study shows that increased DPP4 activities are positively and independently associated with subclinical atherosclerosis in type 2 diabetes. Our findings suggest of potential role of DPP4 in the pathogenesis of subclinical atherosclerosis and in the prevention and management of this disease.

Increased plasma DPP4 activities predict new-onset atherosclerosis in association with its proinflammatory effects in Chinese over a four year period: A prospective study.

OBJECTIVE: DPP4, a novel proinflammatory cytokine, is involved in the inflammatory process through its interaction with IGF-II/M6P receptor. We aimed to investigate whether it could predict new-onset atherosclerosis in Chinese. METHODS: A prospective study was conducted of 590 adults (213 men and 377 women) aged 18-70 years without atherosclerosis examined in 2007(baseline) and 2011(follow-up). Circulating DPP4 activity, inflammatory markers, IGF-II/M6P receptor and common carotid artery Intima-Media Thickness (C-IMT) were measured at baseline and four years later. RESULTS: At baseline, individuals in the highest quartile of DPP4 activity had higher age, WHR, BMI, SBP, fasting insulin, 2h-PG, TG, LDL-C, IL-6, hs-CRP, IGF-II/M6P-R, C-IMT and lower HDL-C compared with individuals in the lowest quartile. After a 4-year follow-up, 71 individuals developed atherosclerosis. In multiple linear regression analysis, baseline DPP4 activity was an independent predictor of an increase in inflammatory markers, IGF-II/M6P receptor, and C-IMT over a 4-year period (all P < 0.01). In multivariable-adjusted models, the odds ratio (OR) for incident atherosclerosis comparing the highest with the lowest quartiles of DPP4 activity was 3.17 (95%CI 1.33-7.58) after adjustment for confounding risk factors (P = 0.009). The incidence of atherosclerosis owing to DPP4 activity increased by 12.41%. CONCLUSIONS: DPP4 activity is an important predictor of the onset of inflammation and atherosclerosis in apparently healthy Chinese. This finding may have important implications for understanding the proinflammatory role of DPP-4 in the pathogenesis of atherosclerosis.
