Fungal infections have emerged as a critical public health issue endangering human health. However, the existing arsenal of antifungal agents is limited in diversity and is commonly plagued by drawbacks including narrow antimicrobial spectrums and the frequent emergence of drug resistance, which severely compromises the efficacy of clinical treatments. Pathogenic fungi can develop extensive adaptability to currently available drugs through multiple mechanisms, which are mainly manifested in three aspects: drug resistance, tolerance and persistence. The molecular mechanisms and regulatory pathways underlying drug resistance, tolerance and persistence in pathogenic fungi were systematically summarized in this review, and the counteractive strategies such as combination therapy and the development of novel antifungal agents were further discussed, which aimed to provide theoretical basis and practical reference for the precision treatment of fungal infections.

ObjectiveTo explore the construction of a risk assessment indicator system for common infectious diseases in Shanghai’s childcare institutions, and to provide a reference standard for the prevention and control of infectious diseases, staff training and system construction in childcare institutions. MethodsBy combining the Delphi method with the literature review and expert consultation, the hierarchical dimensions and items at all levels of the risk assessment indicator system for common infectious diseases in Shanghai’s childcare institutions were constructed, and the weighting coefficients were determined by analytic hierarchy process. ResultsA total of 14 experts from the field of childcare institutions, infectious disease control, child healthcare and health supervision participated in the Delphi consultation. The system consisted of four core dimensions: organizational management, team building, hardware equipment, and infectious disease surveillance and disposal, with the weighting coefficients of 0.285 9, 0.261 6, 0.204 3 and 0.248 2, respectively. The evaluation indicator system consisted of 4 primary indicators, 15 secondary indicators and 45 tertiary items. The positivity coefficients of the two rounds of Delphi consultation were 0.93 and 1.00, the authority coefficients were both 0.81, and the Kendall’s coefficient of concordance were 0.44 and 0.49, respectively (P<0.01). ConclusionThe high expert engagement and coordination indicate that organizational management and team building remain the critical priorities for infectious disease prevention and control in Shanghai’s childcare institutions. It is recommended to strengthen financial investment, improve institutional mechanisms, and enhance personnel reserves and capacity building for healthcare teachers, thereby systematically upgrading the infectious disease control capabilities of childcare institutions.

ObjectiveTo understand the infection characteristics of multidrug-resistant organisms (MDROs) in hospitalized patients in a tertiary sentinel hospital in Shanghai, so as to provide an evidence for the development of targeted prevention and control measures. MethodsData of MDROs strains and corresponding medical records of some hospitalized patients in a hospital in Shanghai from 2021 to 2023 were collected, together with an analysis of the basic information, clinical treatment, underlying diseases and sources of sample collection. ResultsA total of 134 strains of MDROs isolated from hospitalized patients in this hospital were collected from 2021 to 2023 , including 63 strains of methicillin-resistant Staphylococcus aureus (MRSA), 57 strains of carbapenem-resistant Acinetobacter baumannii (CRAB), and 14 strains of carbapenem-resistant Klebsiella pneumoniae (CRKP). Of the 134 strains, 30 strains were found in 2021, 47 strains in 2022 and 57 strains in 2023. The male-to-female ratio of patients was 2.05∶1, with the highest percentage (70.90%) in the age group of 60‒<90 years. The primary diagnosis was mainly respiratory disease, with lung and respiratory tract as the cheif infection sites. There was no statistically significant difference in the distribution of strains between different genders and infection sites (P>0.05). However, the differences in the distribution of strains between different ages and primary diagnosis were statistically significant (P<0.05). Patients who were admitted to the intensive care unit (ICU), had urinary tract intubation, were not artery or vein intubated, were not on a ventilator, were not using immunosuppresants or hormones, and were not applying radiotherapy or chemotherapy were in the majority. There was no statistically significant difference in the distribution of strains for whether received radiotherapy or chemotherapy or not (P>0.05), while the differences in the distribution of strains with ICU admission history, urinary tract intubation, artery or vein intubation, ventilator use, and immunosuppresants or hormones use or not were statistically significant (all P<0.05). The type of specimen was mainly sputum, the hospitalized ward was mainly comprehensive ICU, the sampling time was mainly in the first quarter throughout the year, the number of underlying diseases was mainly between 1 to 2 kinds, the application of antibiotics ≥4 kinds, and those who didn’t receive any surgery recently accounted for the most. There were statistically significant differences in the distribution of strains between different specimen types, wards occupied and history of ICU stay (P<0.05), but no statistically significant difference in the distribution of strains between different sampling times, number of underlying diseases and types of antibiotics applied (P>0.05). ConclusionThe situation of prevention and control on MDROs in this hospital is still serious. Focus should be placed on high-risk factors’ and infection monitoring and preventive measures should be strengthened to reduce the incidence rate of MDROs infection.

Objective:To investigate the correlation between platelet distribution width(PDW)and cerebral microbleeds(CMB)in the middle-aged and elderly population.Methods:A total of 2 839 subjects who underwent cranial magnetic resonance imaging(MRI)examination at Lishui Hospital of Zhejiang University from May 2016 to December were enrolled in this cross-sectional study.According to MRI results, subjects were divided into the CMB group(n=525)and the non-CMB group(n=2 314). Clinical data and PDW levels were compared between the two groups.CMB-related factors were analyzed by using a logistic regression equation.A receiver operating characteristics(ROC)curve was drawn to analyze the value of PDW levels in predicting the incidence of CMB.Results:The percentage of males, the proportion of smokers, the number of subjects with diabetes and serum creatinine levels were higher in the CMB group than in the non-CMB group[(55.05%(289/525) vs.45.12%(1 044/2 314), 42.67%(224/525) vs.34.67%(802/2 314), 12.76%(67/525) vs.9.51%(220/2 314), (68.91±21.38)μmol/L vs.(66.45±15.40)μmol/L, all P<0.05]. PDW levels were higher in the CMB group than in the non-CMB group(15.52±2.49)% vs.(14.67±2.90)%, χ2=93.75, P<0.05). Multivariate logistic regression analysis showed that the PDW level was an independent risk factor for CMB in the middle-aged and elderly population( OR=1.13, P<0.05). The area under the ROC curve(AUC)of PDW in predicting the incidence of CMB was 0.582, and with 15.95% as the optimal threshold value, the sensitivity and specificity were 75.0% and 41.8%.Patients were divided into the high PDW sub-group(n=1 691)and the low PDW sub-group(n=1 083)based on the PDW cutoff at 15.95%.The number of CMB and the incidence of CMB were higher in the high PDW group than in the low PDW group(0.75 vs.0.48, 23.3% or 394/1 691 vs.12.1% or 131/1 083, χ2=30.37 and 51.28, P<0.05). Conclusions:PDW levels are high in middle-aged and elderly patients with CMB, and elevated PDW levels are an independent risk factor for CMB.

BACKGROUND:
Particulate matter (PM), a major component of ambient air pollution, accounts for a substantial burden of diseases and fatality worldwide. Maternal exposure to PM during pregnancy is particularly harmful to children's health since this is a phase of rapid human growth and development.
METHOD:
In this review, we synthesize the scientific evidence on adverse health outcomes in children following prenatal exposure to the smallest toxic components, fine (PM
RESULTS:
Maternal exposure to fine and ultrafine PM directly and indirectly yields numerous adverse birth outcomes and impacts on children's respiratory systems, immune status, brain development, and cardiometabolic health. The biological mechanisms underlying adverse effects include direct placental translocation of ultrafine particles, placental and systemic maternal oxidative stress and inflammation elicited by both fine and ultrafine PM, epigenetic changes, and potential endocrine effects that influence long-term health.
CONCLUSION
Policies to reduce maternal exposure and health consequences in children should be a high priority. PM
