Invasive fungal infections (IFIs) have become prominent global health threats, escalating the burden on public health systems. The increasing occurrence of invasive fungal infections is due primarily to the extensive application of chemotherapy, immunosuppressive therapies, and broad-spectrum antifungal agents. At present, therapeutic practices utilize multiple categories of antifungal agents, such as azoles, polyenes, echinocandins, and pyrimidine analogs. Nevertheless, the clinical effectiveness of these treatments is progressively weakened by the emergence of drug resistance, thereby substantially restricting their therapeutic utility. Consequently, there is an imperative need to expedite the discovery of novel antifungal agents. This review seeks to present an exhaustive synthesis of novel antifungal drugs and candidate agents that are either under current clinical investigation or anticipated to progress into clinical evaluation. These emerging compounds exhibit unique benefits concerning their modes of action, antimicrobial spectra, and pharmacokinetic characteristics, potentially leading to improved therapeutic outcomes relative to conventional antifungal regimens. It is anticipated that these novel therapeutic agents will furnish innovative treatment modalities and enhance clinical outcomes in managing invasive fungal infections.

Objective Analysing the risk factors for the occurrence of pre-frailty or frailty of the community elderly in Chengdu and constructing a risk prediction model.Methods The general information questionnaire,MNA-SF scale,Changsha version of the MoCA scale,PSQI scale,FRAIL scale,and Traditional Chinese Medicine Constitution Scale for the elderly were used in the cross-sectional survey.A total of 400 elderly people who completed community physical examinations in Chengdu from April 2022 to April 2023 were selected as the research objects.Based on multivariate Logistic regression analysis,the independent influencing factors were determined,and RStudio software was used to construct a risk prediction model nomogram.The physical examination data of 200 elderly people collected in Deyang City from June 2023 to October 2023 were used for external verification.The area under the ROC curve,Hosmer-Lemeshow test and calibration curve,and decision curve were used to evaluate the discrimination,calibration,and clinical practicability of the model.Results Age,abdominal circumference,number of chronic diseases,PSQI score,allergy history,and balanced constitution were independent influencing factors for pre-frailty/frailty in the elderly in the community(P<0.05),and the regression equation was as follows:Logit(P)=0.063×age+0.025×abdominal circumference-1.006×allergy history+0.300×number of chronic diseases+0.082×PSQI-1.013×balanced constitution-8.269.The area under the ROC curve of the modeling group was 0.779(95%CI:0.733-0.825),the sensitivity was 67.1%,the specificity was 76.3%,and the maximum Youden index was 0.434.The area under the ROC curve of the external validation group was 0.783(95%CI:0.709-0.856),the sensitivity was 62.0%,the specificity was 95.0%,and the maximum Youden index was 0.570.The Hosmer-Lemeshow goodness of fit test results of the two groups were χ2=3.285,P=0.915 and χ2=8.376,P=0.398,and the calibration curve fit was good.DCA showed that the threshold probability of clinical benefit was 5%-99%and 21%-98%.Conclusions The pre-frailty/frailty risk prediction model established in this study has good predictive efficacy for the elderly in the community,and the use of this model for screening and early intervention of high-risk populations can be clinically beneficial.

Objective:To evaluate the predictive efficacy of different comorbidity indices for hospitalization due to acute exacerbations in chronic obstructive pulmonary disease (COPD) patients with comorbidities (CO-COPD).Methods:This retrospective cohort study included 259 stable COPD patients with comorbidities from Beijing Tongren Hospital, Capital Medical University, between October 2021 and September 2023, all with ≥1-year follow-up. Patients were categorized into hospitalized ( n=75) and non-hospitalized ( n=184) groups based on acute exacerbation events. Clinical characteristics, comorbidities, and comorbidity indices, including Charlson Comorbidity Index (CCI), COPD-specific Comorbidity Test (COTE), and comorbidities in chronic obstructive lung disease index (COMCOLD) were compared between two goups. Risk facors of hospitalization due to acute exacerbations were analyzed by Cox regression. Modified indices were developed by incorporating additional respiratory comorbidities (asthma, bronchiectasis, lung cancer) weighted by hazard ratios (HRs) from Cox reguression. The predictive performance of different comorbidity indices for hospitalization was assessed by receiver operating characteristic (ROC) curves. Results:Hospitalized patients exhibited lower BMI, FEV 1% predicted, and FEV 1/FVC (all P<0.05), alongside higher modified British Medical Research Coucil (mMRC) scores and COPD assessment test (CAT) scores, eosinophil counts, and Global Initiative for Chronic Obstructive Lung Disease, (GOLD)severity ( t=3.73, Z=-3.43, Z=-2.43, Z=-11.10, Z=-11.32, Z=-1.80, χ2=17.62, all P<0.05); and also higher use rates of inhaled corticosteroid (ICS) and systemic oral corticosteroid (OCS) ( χ2=5.48, 7.15, all P<0.05). The comorbidities of asthma, bronchiectasis, lung cancer, hypertension, coronary atherosclerotic heart disease, anxiety and depression in hospitalized group were significantly higher ( χ2=22.49, 18.30, 15.63, 5.10, 4.68, 7.46, 5.16, all P<0.05), along with the increased CCI and COTE index ( P<0.05). Comorbid asthma, bronchiectasis, and lung cancer were independent risk factors for hospitalization ( HR=1.841, 2.924, and 2.076, respectively; all P<0.05). Original CCI and COTE showed moderate predictive value ( AUC=0.609 and 0.655), while modified CCI, COTE, and COMCOLD demonstrated improved performance ( AUC=0.730, 0.760, and 0.713, respectively). At optimal cutoffs (modified CCI>3.5, COTE>4.5, COMCOLD>6.5), sensitivities were 61.3%, 76.0%, and 58.7%, with specificities of 70.1%, 61.4%, and 72.3%. Age-stratified analysis revealed enhanced predictive utility of modified indices across age groups. Conclusions:CCI, COTE, and COMCOLD provide modest predictive value for hospitalization in CO-COPD. Modified indices incorporating respiratory comorbidities significantly improve risk stratification, offering clinical utility for identifying high-risk patients in primary care settings.

Objective:To investigate the association between serum klotho level and risk of all-cause mortality in the population with diabetic kidney disease (DKD).Methods:It was a retrospective cohort study. DKD patients from the National Health and Nutrition Examination Survey (NHANES) database in the United States, which covered five survey cycles from 2007 to 2016 were selected. Relevant demographic and laboratory examination data were collected, and all-cause mortality was regarded as the endpoint event. Patients were divided into high serum klotho group and low serum klotho group according to the optimal klotho threshold of predicting survival outcomes, and the differences of baseline characteristics between the two groups were compared. The weighted Kaplan-Meier method was used to draw the survival curves of the high and low serum klotho groups during the follow-up period. Log-rank test was used to compare the survival rates between the two groups. Weighted Cox proportional hazards regression analysis and further stratified analysis were used to estimate the correlation between serum klotho level and the risk of all-cause mortality.Results:A total of 633 DKD patients were included in this study, with age of 65 (56, 72) years, and 323 (51.03%) males. Among them, there were 510 patients in the high klotho level (>556.6 ng/L) group, and 123 patients in the low klotho level (≤556.6 ng/L) group. The serum creatinine level in the high klotho level group was significantly lower than that in the low klotho level group ( Z=-2.650, P=0.010), while the estimated glomerular filtration rate (eGFR, Z=2.489, P=0.015) and fasting blood glucose ( Z=2.275, P=0.026) were significantly higher than those in the low klotho level group. There was no statistically significant difference between the two groups in terms of age, gender distribution, racial distribution, proportion of smoking, body mass index, proportion of hypertension, total cholesterol, triglyceride, and urine albumin/creatinine ratio (all P>0.05). The follow-up time was 81 (49, 116) months, and a total of 204 (32.23%) all-cause death events occurred. Kaplan-Meier survival analysis showed that the survival rate of the high klotho level group was significantly higher than that of the low klotho level group (Log-rank test, χ2=4.21, P=0.040). Cox proportional hazards regression analysis showed that, after adjusting for gender, age, race, smoking, body mass index, hypertension, blood glucose, triglyceride, total cholesterol and eGFR, the risk of all-cause death in the low klotho level group was 1.63 times than that in the high klotho level group ( HR=1.63, 95% CI 1.03-2.63). Further stratified analysis showed that there was no interaction effect of age, gender, race and eGFR on the impact between low serum klotho level and the risk of all-cause death (all P>0.05), indicating that the correlation between low serum klotho level and the risk of all-cause death was consistent when DKD individuals were divided into different subgroups. Conclusions:Low serum klotho level are significantly associated with increased risk of all-cause mortality in the DKD population. Maintaining an adequate serum klotho level may reduce the risk of death in DKD patients.

Objective:To preliminarily investigate the effect of blue light on the biological activity of human skin keratinocytes, fibroblasts and melanocytes.Methods:Discarded foreskin tissues were collected from 10 healthy children aged from 3 to 12 years after circumcision surgery in the First Affiliated Hospital of Kunming Medical University from June 2021 to December 2021. After epidermis-dermis separation, selective culture was performed to isolate keratinocytes, fibroblasts, and melanocytes. According to the pre-experiment results, the above three types of cells were irradiated with 440 - 450 nm blue light at doses of 0, 5, 10, 20, 30, and 40 J/cm 2, and then continued to be cultured for 0, 6, 24, and 48 hours. Cell counting kit 8 (CCK8) assay was performed to evaluate cellular proliferative activity at each time point, enzyme-linked immunosorbent assay (ELISA) to detect levels of interleukin (IL) -18, IL-33, nerve growth factor (NGF), and granulocyte-macrophage colony-stimulating factor (GM-CSF) secreted by keratinocytes, as well as levels of IL-33 and keratinocyte growth factor (KGF) secreted by fibroblasts, NaOH lysis method to determine melanin synthesis rates in melanocytes, and Western blot analysis to determine the relative expression of tyrosinase (TYR), tyrosine-related protease 1 (TRP-1) and dopachrome isomerase (DCT) in melanocytes. Two-way analysis of variance was used to analyze group effects, time effects and interaction effects. Results:After irradiation with blue light, the cellular proliferative activity significantly differed among different doses of blue light irradiation groups and different time points in keratinocytes ( Ftime = 516.20, Fdose = 421.20, Finteraction = 25.05, all P < 0.003), fibroblasts ( Ftime = 129.30, Fdose = 477.80, Finteraction = 10.91, all P < 0.003), and melanocytes ( Ftime = 77.61, Fdose = 138.70, Finteraction = 3.50, all P < 0.003) ; immediately after irradiation, the proliferative activity of keratinocytes and fibroblasts was significantly lower in the 20 - 40 J/cm 2 blue light group than in the 0 J/cm 2 blue light group (all P < 0.003), and the proliferative activity of melanocytes was significantly higher in the 5 J/cm 2 blue light group than in the 0 J/cm 2 blue light group ( P < 0.003) ; the proliferative activity of the 3 types of cells showed decreasing trends with the increase of blue light irradiation doses and culture time. ELISA showed that the concentrations of IL-18, IL-33, NGF, and GM-CSF secreted by keratinocytes, as well as the concentrations of IL-33 and KGF secreted by fibroblasts, tended to increase with the increase of blue light irradiation doses and culture time. The melanin synthesis rates in melanocytes significantly differed among different doses of blue light irradiation groups and different time points ( Ftime = 833.50, Fdose = 249.40, Finteraction = 81.38, all P < 0.003) ; during 0 - 24 hours after blue light irradiation, the melanin synthesis rates tended to increase with the increase of blue light irradiation doses and time; during 24 - 48 hours, the melanin synthesis rates showed decreasing trends with the increase of blue light irradiation doses and culture time compared with that at 24 hours after irradiation; 24 hours after irradiation, the melanin synthesis rates were significantly higher in the 5, 10, 20, 30 and 40 J/cm 2 blue light groups (159.50% ± 10.88%, 218.76% ± 8.49%, 333.72% ± 7.72%, 393.29% ± 6.00%, 427.21% ± 8.39%, respectively) than in the 0 J/cm 2 blue light group (102.29% ± 6.57%, all P < 0.003). The relative expression of TYR ( Ftime = 67.94, Fdose = 28.99, Finteraction = 3.71, all P < 0.003), TRP-1 ( Ftime = 21.73, Fdose = 8.38, both P < 0.003) and DCT ( Ftime = 34.51, Fdose = 11.79, both P < 0.003) in melanocytes significantly differed among different doses of blue light irradiation groups and different time points, and tended to increase with the increase of blue light irradiation doses and culture time. Conclusion:Blue light irradiation at doses of 5 - 40 J/cm 2 could inhibit the proliferative activity of human skin keratinocytes, fibroblasts, and melanocytes, and the inhibitory effect tended to increase with the increase of blue light irradiation doses, except an enhancing effect on the proliferative activity of melanocytes observed immediately after irradiation with blue light at 5 J/cm 2; additionally, blue light irradiation at 5 - 40 J/cm 2 could enhance the expression of melanin synthesis-related enzymes in melanocytes, and increase the melanin synthesis rate in melanocytes over a short period of time.
