Objective: To investigate the prevalence of hypertension, diabetes and hyperlipidemia among HIV/AIDS patients aged 50 years and above receiving antiretroviral therapy (ART) in Wuxi City, Jiangsu Province, so as to provide insights into the prevention and intervention of chronic diseases for these populations. Methods: The HIV/AIDS patients aged 50 years and above receiving ART were recruited at designated HIV/AIDS medical institutions in Wuxi City using the convenient sampling method from March to June 2024. Demographic information, treatment status and self-reported prevalence of hypertension, diabetes and hyperlipidemia were collected through questionnaire surveys. Factors affecting the prevalence of chronic diseases were analyzed using a multivariable logistic regression model. Results: A total of 830 HIV/AIDS patients receiving ART were surveyed, including 656 males (79.04%) and 375 patients aged 50 to <60 years (45.18%). Among them, 366 patients reported having at least one type of chronic disease, including hypertension, diabetes and hyperlipidemia, with a self-reported prevalence rate of 44.10%. Specifically, 280, 114 and 61 patients reported having hypertension, diabetes and hyperlipidemia, with the self-reported prevalence rates of 33.73%, 13.73% and 7.35%, respectively. Multivariable logistic regression analysis showed that male patients (OR=1.725, 95%CI: 1.187-2.507), those with monthly income less than 3 000 yuan (OR=1.521, 95%CI: 1.122-2.063), those with body mass index of 24 kg/m2 and above (OR=1.577, 95%CI: 1.168-2.130), those who initiated ART at ages of 50 years and above (50 to <60 years, OR=1.535, 95%CI: 1.052-2.238; ≥60 years, OR=3.322, 95%CI: 2.191-5.038), those with ART duration of 10 years and above (OR=2.069, 95%CI: 1.419-3.017), and those who received non-first-line regimens (OR=1.776, 95%CI: 1.304-2.418) had higher risks of developing at least one type of chronic disease, including hypertension, diabetes and hyperlipidemia. Conclusions The self-reported prevalence of at least one type of chronic disease, including hypertension, diabetes and hyperlipidemia among HIV/AIDS patients aged 50 years and above receiving ART in Wuxi City was 44.10%. Gender, monthly income, body mass index and ART status are the main influencing factors for the risk of chronic diseases.

Anxiety disorder is a major symptom of autism spectrum disorder (ASD) with a comorbidity rate of ~40%. However, the neural mechanisms of the emergence of anxiety in ASD remain unclear. In our study, we found that hyperactivity of basolateral amygdala (BLA) pyramidal neurons (PNs) in Shank3 InsG3680 knock-in (InsG3680^+/+) mice is involved in the development of anxiety. Electrophysiological results also showed increased excitatory input and decreased inhibitory input in BLA PNs. Chemogenetic inhibition of the excitability of PNs in the BLA rescued the anxiety phenotype of InsG3680^+/+ mice. Further study found that the diminished control of the BLA by medial prefrontal cortex (mPFC) and optogenetic activation of the mPFC-BLA pathway also had a rescue effect, which increased the feedforward inhibition of the BLA. Taken together, our results suggest that hyperactivity of the BLA and alteration of the mPFC-BLA circuitry are involved in anxiety in InsG3680^+/+ mice.

Objective:To understand the uptake of post-exposure prophylaxis (PEP) and related factors among male sex workers (MSW) and provide references for the promotion of PEP.Methods:A cross-sectional study was conducted using convenience sampling to recruit MSW participants with the help of a community-based organization in October 2023, in Wuxi City, Jiangsu Province. The sample size was estimated at 340 people. A self-administered questionnaire was used to collect their social demographic characteristics, sexual behaviors, knowledge, beliefs, and uptake of PEP. A logistic regression model was used to analyze factors associated with the uptake of PEP in MSW. The SPSS 26.0 software was used for statistical analysis.Results:A total of 357 participants were recruited, mainly aged 18-20 (55.7%,199/357), unmarried (94.4%,337/357), and having an education background of junior high school or below (50.1%,179/357). Among 357 participants, 64.4% (230/357) knew about PEP, 51.0% (182/357) believed in the efficacy of PEP, and 13.4% (48/357) had experience of using PEP. Among 68 respondents having high-risk sexual behaviors in the past 3 months, 17.6% (12/68) have had uptake of PEP. Multivariable logistic regression analysis showed that group sex with men in the past 3 months (a OR=7.51, 95% CI: 1.37-41.09), HIV testing in the past 3 months (a OR=2.89, 95% CI: 1.16-7.16), the experience of using pre-exposure prophylaxis (a OR=30.18,95% CI: 12.60-72.24) and believing in the efficacy of PEP (a OR=2.94, 95% CI: 1.04-8.29) were the associated factors with the uptake of PEP in MSW. Conclusions:Although the overall uptake rate of PEP in MSW was high, the proportion of using PEP was still low among participants having high-risk sexual behaviors in the past 3 months. Therefore, it is necessary to strengthen HIV risk awareness education considering their characteristics and promote timely uptake of PEP to interrupt HIV transmission.

Anthropometric indexes play a crucial role in identifying obesity. However, as an internationally commonly used indicator of obesity diagnosis, BMI has limitations in distinguishing lean body mass from fat mass. The weight-adjusted waist index (WWI), a novel anthropometric index, assesses adiposity through standardized waist circumference for weight, which presents an excellent capacity to predict the morbidity and mortality risks of various diseases. However, research on WWI is still in the exploratory stage, and there is a lack of unified standards for using this indicator to determine obesity. In addition, its potential application in children and adolescents also urgently needs to be explored. Therefore, this article comprehensively summarizes and compares the distinctive characteristics between WWI and other obesity-related anthropometric indexes. Bibliometric methods are used to analyze the hotspots and trends of WWI-related research, and we focus on discussing the value of WWI in predicting adverse health outcomes, including cardiovascular disease, diabetes, liver and kidney diseases. We aim to promote the application of WWI in a broader field and fully demonstrate its important public health significance and broad application prospects.

This paper presented the prenatal genetic analysis of a case of mosaic trisomy 2 combined with uniparental disomy 2. The pregnant women underwent non-invasive prenatal testing in Zhuhai Center for Maternal and Child Health Care on February 2019, which indicated an increased number of chromosome 2. Subsequently, amniocentesis was performed at 21 +2 weeks for prenatal diagnosis. No abnormalities were detected through the karyotype analysis of amniotic fluid cells. Chromosome microarray analysis of uncultured amniotic fluid cells revealed a duplication of 2.3 copies in chromosome 2 and 64.3 Mb regions of homozygosity in the 2q21.2q33.1 region. The comparison of single nucleotide information on fetus-parent chromosome 2 showed that the regions of homozygosity of the fetal 2q21.2q33.1 was paternal uniparental isodisomy (2), with the rest of chromosome 2 being paternal uniparental heterodisomy (2).Ultrasound results at 27 +6, 31 +6, and 34 +5 weeks of gestation showed continued exacerbation of fetal growth retardation with placental abnormalities and fetal blood flow spectrum abnormalities. Due to threatened preterm delivery at 35 +3 weeks, The pregnant woman chose to give up the fetus and delivered a stillbirth.

Objectives:To determine the effect of glucose-6-phosphate-dehydrogenase (G6PD) deficiency on patients’ complications and prognosis following allogeneic stem cell hematopoietic transplantation (allo-HSCT) .Methods:7 patients with G6PD deficiency (study group) who underwent allo-HSCT at Peking University People's Hospital from March 2015 to January 2021 were selected as the study group, and thirty-five patients who underwent allo-HSCT during the same period but did not have G6PD deficiency were randomly selected as the control group in a 1∶5 ratio. Gender, age, underlying diseases, and donors were balanced between the two groups. Collect clinical data from two patient groups and perform a retrospective nested case-control study.Results:The study group consisted of six male patients and one female patient, with a median age of 37 (range, 2-45) years old. The underlying hematologic diseases included acute myeloid leukemia ( n=3), acute lymphocytic leukemia ( n=2), and severe aplastic anemia ( n=2). All 7 G6PD deficiency patients achieved engraftment of neutrophils within 28 days of allo-HSCT, while the engraftment rate of neutrophils was 94.5% in the control group. The median days of platelet engraftment were 21 (6–64) d and 14 (7–70) d ( P=0.113). The incidence rates of secondary poor graft function in the study group and control group were 42.9% (3/7) and 8.6% (3/35), respectively ( P=0.036). The CMV infection rates were 71.4% (5/7) and 31.4% (11/35), respectively ( P=0.049). The incidence rates of hemorrhagic cystitis were 57.1% (4/7) and 8.6% (3/35), respectively ( P=0.005), while the bacterial infection rates were 100% (7/7) and 77.1% (27/35), respectively ( P=0.070). The infection rates of EBV were 14.3% (1/7) and 14.3% (5/35), respectively ( P=1.000), while the incidence of fungal infection was 14.3% (1/7) and 25.7% (9/35), respectively ( P=0.497). The rates of post-transplant lymphoproliferative disease (PTLD) were 0% and 5.7%, respectively ( P=0.387) . Conclusions:The findings of this study indicate that blood disease patients with G6PD deficiency can tolerate conventional allo-HSCT pretreatment regimens, and granulocytes and platelets can be implanted successfully. However, after transplantation, patients should exercise caution to avoid viral infection, complications of hemorrhagic cystitis, and secondary poor graft function.

Objective:To analyze the causes and demographic characteristics of pre-engraftment mortality in patients who underwent allogeneic hematopoietic stem cell transplantation (allo-HSCT) and investigate the risk factors and measures for preventing pre-engraftment mortality.Methods:A retrospective case analysis, involving a total of 7 427 patients who underwent allo-HSCT at Peking University People’s Hospital between January 2016 and July 2023, was conducted.Results:Among the 7 427 patients who underwent allo-HSCT, 56 cases (0.75% ) experienced pre-engraftment mortality. The median time to death for these 56 patients was +7 (-3 to +38) days after stem cell infusion. The median times to death for patients with acute leukemia (AL), severe aplastic anemia (SAA), and myelodysplastic syndrome (MDS) were +11 (-1 to +38), +3 (-1 to +34), and +16 (-1 to +38) days, respectively ( P=0.013). The main causes of pre-engraftment mortality were infection (39.3% ), cardiac toxicity (28.6% ), and intracranial hemorrhage (26.8% ). Infection was the most common cause of pre-engraftment mortality in patients with AL and MDS (55.0% and 60.0% ), whereas cardiac toxicity was predominantly observed in patients with SAA (71.4% ), with no cases in patients with AL and only one case in patients with MDS. Among patients who died from intracranial hemorrhage, 53.3% had severe infections. The median times to death for infection, cardiac toxicity, and intracranial hemorrhage was +11 (-1 to +38), +2.5 (-1 to +17), and +8 (-3 to +37) days, respectively ( P<0.001) . Conclusions:Infection is the primary cause of pre-engraftment mortality in allo-HSCT, and severe cardiac toxicity leading to pre-engraftment mortality should be closely monitored in patients with SAA.

Human parvovirus B19 (HPVB19) belongs to Parvoviridae, a genus of erythrovirus, and has been associated with various human diseases, and HPVB19 infection is one of the most important causes of refractory anemia after allogeneic hematopoietic stem cell transplantation (allo-HSCT). This study retrospectively analyzed 24 patients with HSCT combined with HPVB19 infection to collate and summarize the clinical presentation, treatment, and regression of patients with combined HPVB19 infection after allo-HSCT and provide experience in the management of HPVB19 infection after allo-HSCT. The median age of the patients with HPVB19 infection was 25 years, and the median time of infection occurrence was +107 days after transplantation, and 22 (91.7% ) had anemia with a median hemoglobin (HGB) level of 77.5 (46-149) g/L, and 13 (54.2% ) had new-onset anemia or persistent decline in HGB. The median length of hospital stay was 19 days. Among patients with new-onset anemia or persistent decline in HGB, the mean increase in HGB after treatment with intravenous immunoglobulin and/or antiviral therapy was 15.69 g/L, and treatment was effective in 10 (76.92% ) patients. HPVB19 infection should be alerted to the development of refractory anemia after HSCT; despite the lack of specific treatment, the overall prognosis of HPVB19-infected patients is good.
