A real-world study of infectious complications of venetoclax combined with decitabine or azacitidine in adult acute myeloid leukemia.

PURPOSE: The purpose of this study was to identify the incidence, sites and main pathogens, and risk factors for infectious complications occurring in patients with adult acute myeloid leukemia (AML) during the first course of venetoclax combined with decitabine or azacitidine. METHODS: A retrospective cohort analysis was performed of 81 patients with AML older than 14 years who received the first cycle of venetoclax combined with a hypomethylating agent (HMA) between March 2018 and March 2021 at our institution. Infectious complications, if any, were documented. RESULTS: Among a total of 81 cases of AML, 59 (72.8%) patients occurred infections, including fever without an identifiable source (28.8%), clinically documented infections (40.7%), and microbiologically documented infections (30.5%). The most commonly isolated organism in culture was Candida albicans, followed by Klebsiella pneumonia, and Pseudomonas aeruginosa. The 4-week and 8-week mortality rates were 3.7% and 7.4%, respectively. In multivariate analysis, a high proportion of blasts in bone marrow, decreased hemoglobin level, and fever with or without a documented infection at baseline were significant independent risk factors for infectious complications. CONCLUSION: Compared with conventional chemotherapy, the incidence of infectious complications of venetoclax combined with decitabine or azacitidine significantly decreased. Pretreatment high leukemia burden and fever were independent risk factors for infections.

Risk of birth defects in children conceived by artificial oocyte activation and intracytoplasmic sperm injection: a meta-analysis.

BACKGROUND: Whether artificial oocyte activation (ICSI-AOA) will increase the risk of birth defects remains controversial. Thus, we performed this study to evaluate the risk of birth defects and further compare the incidence of different birth defects types (chromosomal aberrations and non-chromosomal aberrations) in children conceived by ICSI-AOA and conventional intracytoplasmic sperm injection (ICSI) in an enlarged sample size. METHOD: A comprehensive review of the literatures comparing birth defects in children conceived by ICSI-AOA and conventional ICSI by October 2020 was performed in PubMed, Embase, Cochrane Libraries, Web of Science, and Chinese databases including China National Knowledge Infrastructure, China Biology Medicine disc and Wan Fang. Risk ratios (RR) and 95% confidence intervals (CI) were calculated. RESULTS: Five studies were included in the final analysis. Compared with conventional ICSI, ICSI-AOA did not increase the birth defects rate (RR = 1.27, 95%CI 0.70-2.28) of children. Furthermore, in a subgroup analysis, birth defects were classified into two types (chromosomal aberrations and non-chromosomal aberrations) in four studies and no statistical difference were revealed. CONCLUSION: Our analysis indicates that ICSI-AOA represents no significant difference in the prevalence of major birth defects or types of birth defects (chromosomal aberrations and non-chromosomal aberrations) comparing with conventional ICSI. This conclusion may provide clinicians evidence-based support in patient counseling and instruction of the application and safety concern about ICSI-AOA.

Combined indigenous yeast strains produced local wine from over ripen Cabernet Sauvignon grape in Xinjiang.

Cabernet Sauvignon grape produced in Xinjiang (China) is often overripe, with unusually high sugar content, which impedes utilization. We aimed to establish the optimal combination of indigenous yeast strains to produce a new sweet wine from the overripe grape. Five yeast strains with pronounced enological characteristics were selected from 88 indigenous yeast isolates. Using a series of co-fermentation experiments with different inoculated strategies, we achieved optimal co-fermentation with a combination of strains SC19 and NS68, later identified as Saccharomyces cerevisiae and Pichia kudriavzevii, respectively, simultaneously inoculated in a 1:1 ratio at the early stage of fermentation. The combination was characterized by vigorous fermentation with high resistance to 457.13 g/L sugar and high alcohol yield (16.01% vol). The sweet wine contained 17 aromatic compounds with odor activity value (OAV) ≥ 1 and pronounced sweet fruit, floral, herbaceous, and caramel odors. The co-fermentation has a good potential for utilization of overripe Cabernet Sauvignon grape.

In view of the particularity of microdialysis technology and its great differences from traditional sampling and pretreatment methods, the metabonomics process based on microdialysis technology has certain similarities with traditional metabonomics research, and its basic process has some particularity. Advantages and basic strategies of metabonomics research by microdialysis technology are systematically summarized for researchers' reference.

Levels of Furaneol in Msalais Wines: A Comprehensive Overview of Multiple Stages and Pathways of Its Formation during Msalais Winemaking.

4-Hydroxy-2,5-dimethyl-3(2H)-furanone (furaneol) is present in food. It has a caramel-like flavor, which affects the quality of food, and is formed via multiple pathways. Msalais is a traditional wine fermented from boiled local grape juice in Xinjiang (China). It has a strong caramel odor, which suggests high furaneol content. Furaneol formation during Msalais-making had not been investigated to date. Here, high-performance liquid chromatography and different fermentation models of Msalais-making were used to investigate the furaneol content and formation during Msalais-making. The furaneol content of Msalais is high, between 27.59 ± 0.493 mg/L and 117.6 ± 0.235 mg/L. It is formed throughout the entire Msalais-making process. The formation pathways include the Maillard reaction and chemical hydrolysis of bound furaneol during grape juice concentration; enzymatic release and/or chemical acidic hydrolysis of furaneol glucosides, and biosynthesis from Maillard products and d-fructose-1,6-diphosphate during fermentation; chemical transformation of Maillard products at room temperature (16-25 °C) and hydrolysis of furaneol glucosides during storage. Importantly, furaneol is formed by an efficient biotransformation of Maillard products. These findings suggest that furaneol content can be used as an important indicator of wine quality, and could be controlled by controlling the grape quality, grape juice concentration, fermentation, and wine storage.

[Brain lipidomics of intervention effect of Salviae Miltiorrhizae Radix et Rhizoma and Chuanxiong Rhizoma on ischemic stroke based on UPLC-Q-TOF-MS technique].

The aim of this paper was to investigate the intervention effect of Salviae Miltiorrhizae Radix et Rhizoma and Chuanxiong Rhizoma on brain lipid metabolism in rats with ischemic stroke. The ischemic stroke rat model was established by middle cerebral artery occlusion( MCAO) method. The brain tissues were collected after the last administration with Salviae Miltiorrhizae Radix et Rhizoma and Chuanxiong Rhizoma decoction lyophilizate. UPLC-Q-TOF-MS was used to carry out the brain lipidomics study. The lipidomics data were processed with the OPLS-DA model to find out the lipid regulation effect of Salviae Miltiorrhizae Radix et Rhizoma combined with Chuanxiong Rhizoma on ischemic stroke. The results showed that Salviae Miltiorrhizae Radix et Rhizoma and Chuanxiong Rhizoma decoction lyophilized powder can significantly alleviate brain lipidomics profiles in middle cerebral artery occlusion model rats. Eleven differential lipid metabolites in ischemic stroke model were identified. In this experiment,the protective effects of Salviae Miltiorrhizae Radix et Rhizoma and Chuanxiong Rhizoma decoction lyophilized powder on cerebral ischemia injury was verified,which might be related to the regulation of abnormal lipid metabolism.

Correlation between Quality and Geographical Origins of Poria cocos Revealed by Qualitative Fingerprint Profiling and Quantitative Determination of Triterpenoid Acids.

Poria cocos (Schw.) Wolf (PC) is a well-known saprophytic fungus, and its sclerotium without the epidermis (PCS) is widely used in traditional Chinese medicine and as a functional food in many countries. PCS is normally collected from multiple geographical regions, but whether and how the quality of PCS correlates with where it grows have not been determined. This correlation could be significant both for quality control and optimum utilization of PCS as a natural resource. In this study, a qualitative fingerprint profiling method performed by ultra-performance liquid chromatography (UHPLC) with diode array detection (DAD) combining quadrupole time-of-flight-mass spectrometry (QTOF-MS/MS) and a quantitative UHPLC coupled with triple quadrupole mass spectrometry (QqQ-MS/MS) approach were established to investigate whether and how the quality of PCS correlates with its collection location. A standard fingerprint of PCS was generated by median simulation of 25 tested samples collected from four main producing areas of China, and similarity analysis was applied to evaluate the similarities between the fingerprints of samples and the standard fingerprint. Twenty three common peaks occurring in the fingerprint were unequivocally or tentatively identified by UHPLC-QTOF-MS/MS. Meanwhile, principal component analysis (PCA), supervised orthogonal partial least squares-discriminate analysis (OPLS-DA) and hierarchical cluster analysis (HCA) were employed to classify 25 batches of PCS samples into four groups, which were highly consistent with the four geographical regions. Ten compounds were screened out as potential markers to distinguish the quality of PCS. Nine triterpene acids, including five compounds that played important roles in the clusters between different samples collected from the four collection locations, were simultaneously quantified by using the multiple reaction monitoring (MRM) mode of UHPLC-QqQ-MS/MS. The current strategy not only clearly expounded the correlation between quality and geographical origins of PCS, but also provided a fast, accurate and comprehensive qualitative and quantitative method for assessing the quality of PCS.

Influence of blood glucose level on the prognosis of patients with diabetes mellitus complicated with ischemic stroke.

We carried out this meta-analysis for the aim of exploring the influence of diabetes mellitus (DM) on the prognosis of patients with ischemic stroke. Relevant studies were identified using computerized databases supplemented with manual search strategies. The included studies were strictly followed the inclusion and exclusion criteria. Case-control studies which related to the influence of DM on the prognosis of patients with ischemic stroke were selected. Statistical analyses were implemented with the STATA version 12.0 statistical software. Our current meta-analysis initially retrieved 253 studies (227 in Chinese and 26 in English), 13 studies (6 in English and 7 in Chinese) were eventually incorporated in this meta-analysis. These 13 case-control studies included 8463 patients altogether (3249 patients with DM complicated with ischemic stroke and 5214 patients with ischemic stroke). The results of this meta-analysis manifested that there was a significant difference of the blood glucose level at 48 h after stroke between patients with DM complicated with ischemic stroke and patients with ischemic stroke (standard mean difference [SMD] =1.27, 95% confidence interval [CI] =0.02-2.51, P = 0.047); however, the effectiveness, fatality, and the National Institutes of Health Stroke Scale (NIHSS) score in patients with DM complicated with ischemic stroke, and patients with ischemic stroke had no significant difference (effectiveness: risk ratio [RR] = 0.88, 95% CI = 0.75-1.03, P = 0.121; fatality: RR = 1.29, 95% CI = 0.97-1.71, P = 0.081; NIHSS score: SMD = -0.14, 95% CI = -1.56-1.28, P = 0.849). The current evidence suggests that there is statistical difference of the blood glucose level at 48 h after stroke between patients with DM complicated with ischemic stroke and patients with ischemic stroke, but there is no statistical difference of prognostic indicators between patients in two groups. Thus, our study provides certain clinical value.

Direct stamp of technology or origin on the genotypic and phenotypic variation of indigenous Saccharomyces cerevisiae population in a natural model of boiled grape juice fermentation into traditional Msalais wine in China.

Saccharomyces cerevisiae strains worldwide show genetic and phenotypic diversity and their population substructures are greatly affected by their technological application or geographical origins. Msalais is a traditional wine obtained via a unique method of spontaneous fermentation of local boiled grape juice in Southern Xinjiang. We analyzed 436 indigenous S. cerevisiae strains associated with Msalais fermentation. These strains were highly diverse with respect to the interdelta region and 24 phenotypic traits, with apparent differentiation according to strain origins and technologies used to produce Msalais. The genetic and phenotypic diversity of strains from traditional workshops was higher than in strains from modern plants. These local strains had different origin- or technology-specific fermentative characteristics. Strains growing in large-scale fermentation tanks tolerated high temperature, whereas strains from traditional workshops tolerated high alcohol content (16%) and low temperature (13°C). Almost all the strains were characterized by the highest fermenting vigor, with weak H2S production and no histamine, cadaverine, phenethylamine and tryptamine production. Majority of strains had pronounced autolytic activity with high ß-glucosidase and polygalacturonase activity and alcohol production. Our study reveals a direct stamp of technology or origin on genotypic and phenotypic variation of an indigenous S. cerevisiae population.

Microbial functional diversity responses to 2 years since biochar application in silt-loam soils on the Loess Plateau.

The structure and function of soil microbial communities have been widely used as indicators of soil quality and fertility. The effect of biochar application on carbon sequestration has been studied, but the effect on soil microbial functional diversity has received little attention. We evaluated effects of biochar application on the functional diversities of microbes in a loam soil. The effects of biochar on microbial activities and related processes in the 0-10 and 10-20cm soil layers were determined in a two-year experiment in maize field on the Loess Plateau in China. Low-pyrolysis biochar produced from maize straw was applied into soils at rates of 0 (BC0), 10 (BC10) and 30 (BC30)tha-1. Chemical analysis indicated that the biochar did not change the pH, significantly increased the amounts of organic carbon and nitrogen, and decreased the amount of mineral nitrogen and the microbial quotient. The biochar significantly decreased average well colour development (AWCD) values in Biolog EcoPlates™ for both layers, particularly for the rate of 10tha-1. Biochar addition significantly decreased substrate richness (S) except for BC30 in the 0-10cm layer. Effects of biochar on the Shannon-Wiener index (H) and Simpson's dominance (D) were not significant, except for a significant increase in evenness index (E) in BC10 in the 10-20cm layer. A principal component analysis clearly differentiated the treatments, and microbial use of six categories of substrates significantly decreased in both layers after biochar addition, although the use of amines and amides did not differ amongst the three treatments in the deeper layer. Maize above ground dry biomass and height did not differ significantly amongst the treatments, and biochar had no significant effect on nitrogen uptake by maize seedlings. H was positively correlated with AWCD, and negatively with pH. AWCD was positively correlated with mineral N and negatively with pH. Our results indicated that shifts in soil microbial functional diversity affected by biochar were not effective indicators of soil quality in earlier maize growth periods in this region.

A mixed-method study of effects of a therapeutic play intervention for children on parental anxiety and parents' perceptions of the intervention.

AIM: To examine the effects of a therapeutic play intervention for children on parents' perioperative anxiety, the relationship between parents' and their children's anxiety and to explore parents' perceptions of the intervention. BACKGROUND: Therapeutic play intervention was found to reduce children's perioperative anxiety. Little is known about how such an intervention for children affects their parents' anxiety. DESIGN: A mixed method of randomized controlled trial with qualitative process evaluation was used. METHODS: Ninety-five pairs of parents and children were recruited between November 2011-August 2013 and randomized into a control or an intervention group. The State Anxiety Scale for Children and the State Anxiety Scale for Adults were used to measure children's and parents' anxiety, respectively, at baseline, on surgery day and around 24 hours after surgery. Parents were interviewed about their perceptions of the intervention. Data were analysed using SPSS version 22·0 and thematic analysis. RESULTS: There was no difference in parents' anxiety after participating with their child in the intervention compared with usual care. There were significantly positive relationships between parents' and their children's baseline anxiety and parents' postoperative anxiety and their children's pre-operative anxiety. Four themes were identified: reducing anxiety, increasing knowledge and understanding about anaesthetic procedure, the worthiness of attending the intervention and suggestions for improvement of the intervention. CONCLUSIONS: Therapeutic play intervention had no significant effect on parents' perioperative anxiety. Parents' and their children's perioperative anxiety are correlated. Parents perceived the intervention as helpful preparation for themselves and for their children undergoing elective surgery.

Identification of dominant functional microbes that contribute to the characteristic aroma of Msalais, traditional wine fermented from boiled local grape juice in China.

Msalais is a traditional wine produced from naturally fermented boiled local grape juice in China. It has characteristic dried fruit and caramel odors, mainly attributed to aromatic compounds, such as furaneol and 5-methylfurfural. However, it is unclear how microbes involved in the natural fermentation of Msalais contribute to this characteristic aroma. Here, we analyzed the Msalais-fermenting microbes and aromatic compounds formed during natural Msalais fermentation by using high-throughput sequencing and gas chromatography-mass spectrometry, respectively. The analysis revealed that Saccharomyces cerevisiae, Kazachstania humilis, Lactobacillus plantarum, and Lactobacillus farraginis are the dominant and key functional species that produce high amounts of furaneol and 5-methylfurfural during Msalais fermentation. Of these, K. humilis and L. farraginis are rarely detected during regular wine fermentation. The identified functional species could be used to control typical aromatic characteristics of Msalais.

Novel compound heterozygous mutations in DNAH1 cause primary infertility in Han Chinese males with multiple morphological abnormalities of the sperm flagella.

This study aimed to identify genetic causes responsible for multiple morphological abnormalities of the sperm flagella (MMAF) in the Han Chinese population. Three primary infertile males with completely immobile sperm and MMAF were enrolled. Whole-exome sequencing and Sanger sequencing were performed to identify disease-causing genes. Subsequently, morphological and ultrastructural analyses of sperm flagella were investigated. The probable impact of genetic variants on protein function was analyzed by online bioinformatic tools and immunofluorescence assay. Three patients with dynein axonemal heavy chain 1 (DNAH1) gene compound heterozygous variations were identified. DNAH1 c.7435C>T, p.R2479X and c.10757T>C, p.F3586S were identified in the patient from Family 1, c.11726_11727delCT, p.P3909fs and c.12154delC, p.L4052fs were found in the patient from Family 2, and c.10627-3C>G and c.11726_11727delCT, p.P3909fs existed in the patient from Family 3. Four of these variations have not been reported, and all the mutations showed pathogenicity by functional effect predictions. The absence of the center pair and disorganization of the fibrous sheath were present in sperm flagella at the ultrastructural level. Moreover, the expression of DNAH1 was absent in spermatozoa from the participants, validating the pathogenicity of the variants. All three couples have undergone intracytoplasmic sperm injection (ICSI), and two couples of them became pregnant after the treatment. In conclusion, the newly identified DNAH1 mutations can expand the mutational and phenotypic spectrum of MMAF genes and provide a theoretical basis for genetic diagnosis in MMAF patients. It is recommended to conduct genetic screening in male infertility patients with MMAF and provide rational genetic counseling, and ICSI might be an optimal strategy to help with fertilization and conception for patients with DNAH1 mutations.

The Role of Vesicle Release and Synaptic Transmission in Depression.

Depressive disorder is the leading cause of disability worldwide, yet the mechanisms underlying depression are not fully understood. Vesicle release is essential for synaptic neurotransmission, the abnormalities of vesicle release and synaptic plasticity are associated with various neuropsychiatric disorders. Neural circuits are ensembles of interconnected neurons that collectively perform specific functions. To some extent, depression may be caused by a disruption in the structural and functional connections of the neural circuits underlying emotion regulation. In this review, we summarized the role of abnormalities of vesicle release and synaptic transmission, as well as the related regulatory molecules and signal pathways in the regulation of depression.

Evolution of nonenzymatic browning during the simulated Msalais-production process in models of grape juice.

Msalais is a wine fermented from boiled grape juice. Nonenzymatic browning (NEB) greatly affects the quality of Msalais, but to date its mechanism has not been systematically analyzed. In the current study, the evolution of NEB during Msalais production was investigated using models of grape juice. 5-Hydroxymethylfurfural (5-HMF), browning index (BI), yellowness index (YI), sample absorbance at 420 (A420), and b* increased during heating, with a clear transition point at 110 min. The Maillard reaction (MR) was the major contributor to NEB. Vitamin C (VC) facilitated NEB in the late stage of heating. During heating that lasted over 130 min, glucose contributed to NEB more than fructose, while the reverse was true for heating lasting less than 130 min. Proline (Pro) was the most important amino acid in facilitating NEB. BI and A420 decreased during fermentation, while increasing slightly during wine storage. In conclusion, this study identified the evolution of NEB during the Msalais process, which will facilitate the control of traditional Msalais production for improved wine quality.

Update Knowledge Assessment and Influencing Predictor of Female Fertility Preservation in Oncologists.

OBJECTIVE: This study aims to offer an update assessment of the knowledge of Chinese oncologists on female fertility preservation, and identify the determinants that influence the implementation of fertility preservation. METHODS: A total of 713 Chinese oncologists with different specialties completed the online self-report questionnaire to assess their understanding of fertility risks in cancer treatment, knowledge on female fertility preservation, and perceptions on the barriers in referring patients for fertility preservation. RESULTS: Although most oncologists were familiar with fertility risk in cancer treatment, half of them lacked the knowledge for reproduction and preservation methods. In the multivariable model, oncologists in a hospital with a specialized reproductive institution, positive precaution for fertility risk, and fertility preservation discussion with patients were significantly correlated with the possibility of fertility preservation referral. CONCLUSIONS: The intervention targets based on the update evaluation and identified influencing determinants will be helpful for all the oncofertility researchers, oncologists and institutions in future efforts for well-established female fertility preservation services.

A comparison of postnatal depression and related factors between Chinese new mothers and fathers.

AIMS: This study aims to examine the differences in the prevalence of depression and related factors between new mothers and fathers during the postnatal period. BACKGROUND: Although the transition to motherhood and postnatal depression has been extensively studied, few studies compared maternal and paternal psychological health during the postnatal period. DESIGN: A cross-sectional design was used. METHODS: A total of 376 pairs of new parents participated in this study. The Edinburgh Postnatal Depression Scale, the Perceived Stress Scale and the Social Support Rating Scale were used to measure depression, perceived stress and social support, respectively. We performed paired t-test and multiple regression to analyse the data. RESULTS: No significant difference in the prevalence of postnatal depression was found between the new mothers and fathers (14.9 vs. 12.5%). Fathers experienced similar stress levels as mothers did, while they received lower level of social support than mothers. Perceived stress, social support and partner's Edinburgh Postnatal Depression Scale score were significantly associated with depression for both mothers and fathers. Less sleeping time of infant and a tense relationship between mothers and mother-in-law were related to mothers' depression. The preference for a male baby was associated with fathers' depression. CONCLUSION: Both new mothers and fathers experienced postnatal depression in China. RELEVANCE TO CLINICAL PRACTICE: Clinical nurses should pay attention to psychological health among new parents during postnatal period. Perinatal services, such as antenatal and postnatal education and counselling, should also be provided for fathers.

Aromatic characterization of traditional Chinese wine Msalais by partial least-square regression analysis based on sensory quantitative descriptive and odor active values, aroma extract dilution analysis, and aroma recombination and omission tests.

Msalais is produced from local grape juice in southern Xinjiang (China), by concentration and natural fermentation. In the current study, we combined partial least-square regression analysis based on sensory quantitative descriptive and odor active values (OAVs), aroma extract dilution analysis, and aroma recombination and omission tests to delineate the unique aromatic characteristics of traditional Msalais. Msalais has strong dried fruit, fruit jam, and fruity odors, intermediate-strength caramel and baked odors, and weak floral and herbaceous odors, attributed to 24 key aromatic compounds with OAV ≥1 or flavor dilution ≥4. Furaneol, methionol, and 5-methylfurfural greatly contribute to the dried fruit, fruit jam, and caramel odors, respectively. ß-Phenylethyl alcohol mostly contributes to fruit jam odor. ß -Damascenone has a complicated effect on dried fruit, fruit jam, and floral odors. Fruity esters contribute to fruity odor. Floral odor is attributed to terpenes. These findings allow precise improvement of the variable quality of traditional Msalais.
