Purpose:
To investigate the effect of androgen deprivation therapy (ADT) on health-related quality of life (HRQOL) in Asian men with all stages of prostate cancer.
Materials and Methods:
READT (real-life evaluation of the effect of ADT in prostate cancer patients in Asia) was a multi-center, prospective observational study involving six sites across four Asian populations. We enrolled eligible prostate cancer patients, who opted for ADT alone or in combination without prior neoadjuvant or adjuvant ADT within 12 months. The EuroQoL-5 dimensions, 5 level scale (EQ-5D-5L) utility index scores and visual analog scale (VAS) were evaluated at baseline, month 6 and month 12.
Results:
A total of 504 patients were recruited into READT between September 2016 and May 2020 with 52.9% diagnosed with metastatic prostate cancer. The EQ-5D-5L was evaluable in 442/504 (87.7%) of patients. Overall baseline EQ-5D-5L utility index score was 0.924 (interquartile range [IQR] 0.876–1.000). We observed a statistically significant difference in baseline EQ-5D-5L utility index score among different populations with a median EQ-5D-5L utility index score of 1 for Taiwan & Hong Kong, 0.897 for China and 0.838 for Malaysia. Similar trend was observed throughout multiple treatment time-points. Stage IV prostate cancer were significantly associated with a lower baseline EQ-5D-5L utility index score compared to stage I–III prostate cancer, producing a median disutility value of -0.080. Participants had a high median VAS (80, IQR 70–90), indicating good overall health on average during ADT initiation.
Conclusions
The study highlights the differences in health state utility index scores among various Asian prostate cancer patients receiving ADT at real-world setting. Our findings will be informative and useful in cost-effectiveness evaluation and policy decision making.

To efficiently remove all recurrent lymph nodes (rLNs) and minimize complications, we developed a combination approach that consisted of 68Gallium prostate-specific membrane antigen (PSMA) ligand positron emission tomography (PET)/computed tomography (CT) and integrated indocyanine green (ICG)-guided salvage lymph node dissection (sLND) for rLNs after radical prostatectomy (RP). Nineteen patients were enrolled to receive such treatment. 68Ga-PSMA ligand PET/CT was used to identify rLNs, and 5 mg of ICG was injected into the space between the rectum and bladder before surgery. Fluorescent laparoscopy was used to perform sLND. While extensive LN dissection was performed at level I, another 5 mg of ICG was injected via the intravenous route to intensify the fluorescent signal, and laparoscopy was introduced to intensively target stained LNs along levels I and II, specifically around suspicious LNs, with 68Ga-PSMA ligand PET/CT. Next, both lateral peritonea were exposed longitudinally to facilitate the removal of fluorescently stained LNs at levels III and IV. In total, pathological analysis confirmed that 42 nodes were rLNs. Among 145 positive LNs stained with ICG, 24 suspicious LNs identified with 68Ga-PSMA ligand PET/CT were included. The sensitivity and specificity of 68Ga-PSMA ligand PET/CT for detecting rLNs were 42.9% and 96.6%, respectively. For ICG, the sensitivity was 92.8% and the specificity was 39.1%. At a median follow-up of 15 (interquartile range [IQR]: 6-31) months, 15 patients experienced complete biochemical remission (BR, prostate-specific antigen [PSA] <0.2 ng ml-1), and 4 patients had a decline in the PSA level, but it remained >0.2 ng ml-1. Therefore, 68Ga-PSMA ligand PET/CT integrating ICG-guided sLND provides efficient sLND with few complications for patients with rLNs after RP.

Work-related musculoskeletal disorders (WMSDs) refer to musculoskeletal disorders caused by work or work as the main cause, which are characterized by high prevalence and heavy burden of disease as a global problem. The classification and catalog of occupational diseases is of great significance for guiding the prevention and control of occupational diseases and safeguarding the rights and interests of workers. The types of WMSDs included in the list of occupational diseases vary greatly from country to country, and the regulations on specific pathogenic factors are also inconsistent. By sorting out and analyzing the lists and characteristics of WMSDs at home and abroad, and using the International Statistical Classification of Diseases and Related Health Problems (ICD-10) in occupational health to standardize of WMSDs in various countries, which would lay the foundation for future multi-country WMSDs occupational health registration and disease burden research, and provide a reference for China to revise the WMSDs list.

Objective: This study aims to investigate the sleep quality of pregnant women in Xuhui District, Shanghai, and the related factors of sleep disturbances during pregnancy. Methods: From February 2019 to February 2021, we used online integrated sleep questionnaire (including PSQI, BQ, ESS, AIS) in Shanghai Jiao Tong University School of Medicine Affiliated Sixth People's Hospital, The International Peace Maternity and Child Health Hospitals of China Welfare Institution, and Shanghai Eighth People's Hospital, to investigate the sleep quality across pregnancy. We also collected maternal physical examination results, childbearing history, sociodemographic, and other clinical data. The prevalences and related factors of various sleep disturbances in pregnant women were analyzed, including insufficient/excessive nighttime sleep, low sleep efficiency, difficulty falling asleep, poor sleep quality, insomnia, daytime sleepiness, and high risk of sleep-disordered breathing (SDB). Results: This study includes 1 898 cases in the first trimester (T1), 3 099 cases in the second trimester (T2), and 1 539 cases in the third trimester (T3). Poor sleep quality (38.6%), daytime sleepiness (mild 41.9%, moderate 17.7%, severe 2.1%), and suspicious insomnia (32.3%) are most prevalent among women in T1 (P<0.01). In comparison, short sleep time (2.7%), long sleep time (8.6%), difficulty falling asleep (12.2%), poor sleep efficiency (35.4%), very poor sleep quality (6.7%), clinical insomnia (21.8%), and high-risk SDB (6.4%) are most prevalent among women in T3 (P<0.05). During pregnancy, late gestation (OR=1.016, 95%CI: 1.006-1.025) and multiple induced/drug abortions (OR=1.329, 95%CI: 1.043-1.692) are risk factors for poor sleep quality (PSQI>5), while multiple full-term deliveries (OR=0.800, 95%CI: 0.675-0.949) is its protective factor. Advanced maternal age (OR=0.976, 95%CI: 0.956-0.997), multiple full-term deliveries (OR=0.808, 95%CI: 0.680-0.959), late gestation (OR=0.983, 95%CI: 0.974-0.992) and hypertension (OR=0.572, 95%CI: 0.401-0.814) are protective factors for daytime sleepiness (ESS>6). The high-risk pregnancy category (OR=9.312, 95%CI: 1.156-74.978) is a risk factor for insomnia (AIS≥4), while multiple full-term deliveries (OR=0.815, 95%CI: 0.691-0.961) is its protective factor. High BMI (OR=1.334, 95%CI: 1.270-1.402) and hypertension (OR=4.427, 95%CI: 2.539-7.719) are risk factors for high-risk SDB in pregnant women. Conclusions: The prevalences of various sleep disturbances are high throughout pregnancy. Noticeably, symptoms of maternal SDB develop along with pregnancy. Different types of sleep disturbances are associated with different factors. Women of high-risk pregnancy category, in late gestation, with high BMI, hypertension, a history of induced/drug abortion, or without a history of full-term delivery can be at high risk of sleep disturbances during pregnancy.

RNA binding protein (RBP) plays a key role in gene regulation and participate in RNA translation, modification, splicing, transport and other important biological processes. Studies have shown that abnormal expression of RBP is associated with a variety of diseases. The Musashi (Msi) family of mammals is an evolutionarily conserved and powerful RBP, whose members Msi1 and Msi2 play important roles in the regulation of stem cell activity and tumor development. The Msi family members regulate a variety of biological processes by binding and regulating mRNA translation, stability and downstream cell signaling pathways, and among them, Msi2 is closely related to embryonic growth and development, maintenance of tumor stem cells and development of hematological tumors. Accumulating evidence has shown that Msi2 also plays a crucial role in the development of solid tumors, mainly by affecting the proliferation, invasion, metastasis and drug resistance of tumors, involving Wnt/β-catenin, TGF-β/SMAD3, Akt/mTOR, JAK/STAT, Numb and their related signaling pathways (Notch, p53, and Hedgehog pathway). Preclinical studies of Msi2 gene as a therapeutic target for tumor have achieved preliminary results. This review summarizes the molecular structure, physiological function, role of Msi2 in the development and progression of various solid tumors and the signaling pathways involved.

Compared with human insulin, insulin lispro shows a faster hypoglycemic effect and a higher peak plasma concentration, which can better control postprandial hyperglycemia. In this study, we used a solid phase extraction pretreatment method and liquid chromatography-tandem mass spectrometry (LC-MS/MS) to quantify insulin lispro in rat plasma. Bovine insulin was used as an internal standard. Plasma samples were separated on an ACQUITY UPLC Peptide CSH C18 column (2.1 mm × 50 mm, 1.7 μm) after solid phase extraction. Positive electrospray ionization was performed using multiple reaction monitoring (MRM) with transitions of

Objective:To investigate the correlation between the imaging markers of cerebral small vessel disease (CSVD) and early hematoma expansion (HE) in patients with spontaneous intracerebral hemorrhage (sICH).Methods:Patients with sICH admitted to the Department of Neurology, the Affiliated Hospital of Qingdao University between January 1, 2015 and December 31, 2019 were enrolled retrospectively. All patients received noncontrast CT (NCCT) within 6 h after onset. Within 24 h after the initial NCCT examination, they were reexamed to determine whether HE occurred, and brain MRI examination was completed within 48 h after onset. HE was defined as the increase of hematoma volume on NCCT reexamination by >33% or >6 ml compared with the baseline. NCCT was used to evaluate the abnormal morphology and density signs, including blend sign, swirl sign, black hole sign, island sign, and satellite sign. MRI was used to evaluate CSVD imaging markers, including lacunar infarcts (LIs), enlarged perivascular space (EPVS), white matter hyperintensities (WMHs), cerebral microbleeds (CMBs), and cortical superficial siderosis (CSS). Multivariate logistic regression analysis was used to determine independent risk factors for HE. The receiver operator characteristic (ROC) curve was used to evaluate the predictive ability of imaging markers for HE in patients with sICH. Results:A total of 216 patients with sICH were included. Their age was 57±15 years, 113 (61.6%) were male, 88 (40.7%) had HE, 123 (56.9%) had NCCT signs, 122 (56.5%) had CMBs, 143 (66.2%) had WMHs, 44 (20.4%) had CSS, 25 (11.6%) had LIs, and 31 (14.4%) had EPVS. The baseline hematoma volume, blood calcium, the modified Rankin Scale score and the National Institutes of Health Stroke Scale score at admission, and detection rates of NCCT signs, CMBs, WMHs and CSS in the HE group were significantly higher than those in the non-HE group (all P<0.05). Multivariate logistic regression analysis showed that the blood calcium (odds ratio [ OR] 0.040, 95% confidence interval [ CI] 0.004-0.238; P=0.001), any NCCT signs ( OR 3.275, 95% CI 1.492-7.188; P=0.003), CMBs grade 4 ( OR 3.591, 95% CI 1.146-11.250; P=0.028), CSS ( OR 3.008, 95% CI 1.214-7.452; P=0.017), NCCT signs+ CMBs grade 3 ( OR 3.390, 95% CI 1.035-11.102; P=0.044), NCCT signs+ CMBs grade 4 ( OR 5.473, 95% CI 1.352-22.161; P=0.017), and NCCT signs+ CSS ( OR 3.544, 95% CI 1.215-10.336; P=0.021) were the independent risk factors for HE in patients with sICH. ROC curve analysis showed that the sensitivity of NCCT signs, CMBs and CSS for predicting HE were 81.8%, 64.8% and 34.1%, respectively, and the specificity were 60.2%, 60.9% and 89.1%, respectively. The predictive sensitivity of NCCT signs+ CMBs and NCCT signs+ CSS (59.1% and 30.7%, respectively) was lower than that of single imaging marker, while the specificity (78.1% and 93.7%, respectively) was higher than that of single imaging marker. Conclusions:The imaging markers of CSVD are closely associated with the risk of HE in patients with sICH. Severe CMBs and CSS are the independent risk factors for HE in patients with sICH. The specificity of NCCT signs combined with CSVD imaging markers for predicting HE is increased but the sensitivity decreased.
