Predicting disease prognosis and the efficacy of immunotherapy presents a significant challenge in the treatment of hepatocellular carcinoma (HCC). By analyzing transcriptome sequencing data from 69 patients and identifying differentially expressed immune genes, a prognostic index named the immune-related gene prognostic index (IRGPI) was established by Lasso-Cox regression. The IRGPI, which consists of six key genes, was found to be a significant predictor of poor prognosis in patients with high IRGPI scores. The model’s predictive accuracy was confirmed via receiver operating characteristic (ROC) curve analysis, with area under the curve (AUC) values of 0.85, 0.779, and 0.857 for 1-, 3-, and 5-year survival predictions, respectively. Additionally, patients with high IRGPI scores had increased levels of Treg cells and neutrophils, advanced tumor staging, microvascular invasion grading, and immune checkpoint expression. The IRGPI was also effective in predicting the efficacy of immunotherapy in the IMvigor210 dataset, demonstrating its potential as a valuable tool for assessing patient prognosis and guiding immunotherapy strategies in HCC.

Since the widespread use of combination antiretroviral therapy, the incidence of opportunistic infections has decreased in HIV infection populations. However, HIV-associated lymphoma become the most common causes of cancer death. Little is known about the epidemiology, survival and treatment of HIV-associated lymphoma patients in China as these are less common than HIV-negative lymphoma. We performed a multi-center retrospectively study to analyze the epidemiology, clinical characteristics and outcomes of HIV-associated lymphoma in China. Totally 407 newly diagnosed HIV-associated lymphoma patients at eleven medical centers from July 2008 to October 2021, were analyzed, as the largest cohort reported in China to date. In the entire cohort, including 373 (91.6

OBJECTIVES:To observe the effects of interactive scalp acupuncture on upper limb motor function and activities of daily living in patients with upper limb motor dysfunction after stroke.METHODS:One hundred and twenty patients with upper limb motor dysfunction after stroke were randomly divided into an observation group(60 cases, 2 cases dropped out)and a control group(60 cases, 1 case dropped out). Both groups were treated with routine medication and rehabilitation. The observation group was treated with interactive scalp acupuncture combined with suspension digital occupational therapy, interactive scalp acupuncture was applied at middle 2/5 of the parietal and temporal anterior oblique line, middle 2/5 of the parietal and temporal posterior oblique line and second lateral line of parietal of the hemiparalysis contralateral side, 30 min each time.The control group was treated with suspension digital occupational therapy alone. The treatment was given once a day, 5 times a week for 4 weeks in the two groups. The scores of Fugl-Meyer assessment scale of upper extremity(FMA-UE), action research arm test(ARAT), the modified Barthel index (MBI) and surface electromyography(sEMG)signal of the biceps and triceps on the affected side were observed before and after treatment in the two groups, and the clinical efficacy was evaluated.RESULTS:After treatment, the FMA-UE, ARAT and MBI scores were increased compared with those before treatment in both groups(P<0.05), the changes of the observation group were greater than those in the control group(P<0.05). After treatment, the integrated electromyography(iEMG)value and root mean square(RMS)value of the biceps and triceps on the affected side during elbow flexion and extension were increased compared with those before treatment in both groups(P<0.05), the changes of the observation group were greater than those in the control group(P<0.05). The total effective rate was 94.8%(55/58) in the observation group, which was higher than 83.1%(49/59) in the control group(P<0.05).CONCLUSIONS:Interactive scalp acupuncture could improve upper limb motor function and activities of daily living in patients with upper limb motor dysfunction after stroke.

Background and aims: The systemic immune-inflammation index (SII), neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), and lymphocyte-to-monocyte ratio (LMR) are novel inflammatory biomarkers used to determine various disease prognoses. However, the effects of these systemic inflammatory markers on all-cause mortality in patients with stroke remain unclear. Methods: We used data from the UK Biobank for this prospective analysis. Overall, 6,020 eligible individuals were included. Over a median follow-up of 13.4 years, 1,233 participants died. We examined the effects of systemic inflammatory markers on all-cause mortality using random survival forest (RSF) and Cox proportional hazards models. Covariate adjustments in the Cox model, selected by RSF, included age, sex, body mass index (BMI), Townsend deprivation index, smoking status, alcohol intake frequency, sleep duration, diabetes, and malignant neoplasms. Results: In the marginal effect plots and restricted cubic spline analysis for systemic inflammatory markers, LMR exhibited a linear negative correlation, NLR showed a linear positive correlation, and SII and PLR demonstrated a U-shaped association. After covariates were adjusted, the all-cause mortality risk increased by 14 % for LMR <4 (hazards ratio [HR]: 1.14, 95 % confidence interval [CI]: 1.01-1.29; p = 0.03), by 26 % for NLR >2 (HR: 1.26; 95 % CI: 1.11-1.43; p < 0.001),by 26 % for PLR >175 (HR: 1.26; 95 % CI: 1.07-1.47; p < 0.001), and by 31 % for SII >526 (HR: 1.31; 95 % CI, 1.16-1.47; p = 0.014). In addition, sensitivity analyses, excluding participants who had been followed-up for <2 years and those with malignant neoplasms, yielded results consistent with those of previous research. Conclusion: SII, NLR, PLR, and LMR significantly correlate with all-cause mortality in stroke patients. Thresholds established by the RSF model could potentially refine prognostic decision-making in stroke care.

Background We compared the efficacy fi cacy and safety profiles fi les of ainuovirine (ANV), a new-generation non-nucleoside reverse transcriptase inhibitor (NNRTI), with boosted elvitegravir (EVG), both coformulated with two nucleoside reverse transcriptase inhibitors (NRTIs), in people living with HIV-1 (PLWH) who had achieved virological suppression on previous NNRTI-based antiretroviral (ARV) regimen. Methods This study was a multi-centre, randomised, double-blind, active-controlled, non-inferiority trial recruiting PLWH from 10 clinical centres across China. Main inclusion criteria included age of 18-65 - 65 years (inclusive), and stably staying on an ARV regimen combining an NNRTI with a two-drug NRTI backbone for at least 12 months. Eligible participants must have maintained plasma HIV-1 ribonucleic acid (RNA) titre below 50 copies per mL confirmed fi rmed on two successive tests at an interval of at least one month prior to randomisation. Participants were randomly assigned to receive ANV 150 mg plus lamivudine (3TC) 300 mg, and tenofovir disoproxil fumarate (TDF) 300 mg (ANV/3TC/TDF), or cobicistat (Cobi) 150 mg boosted EVG plus emtricitabine (FTC) 200 mg, and tenofovir alafenamide (TAF) 10 mg. The primary efficacy fi cacy endpoint was the proportion of participants with HIV-1 RNA titre at 50 copies per mL or above at week 48 using the US Food and Drug Administration snapshot algorithm, with a non-inferiority margin of 4 percentage points at a two-side 95% confidence fi dence level. This trial is active, but not recruiting, and is registered with Chinese Clinical Trial Registry (ChiCTR), number ChiCTR2100051605. Findings Between October 2021 and February 2022, 923 patients were screened for eligibility, among whom 762 participants were randomized and had received at least one dose of ANV/3TC/TDF (n = 381) or EVG/Cobi/FTC/ TAF (n = 381). At week 48, 7 (1.8%) participants on ANV/3TC/TDF and 6 (1.6%) participants on EVG/Cobi/FTC/ TAF had plasma HIV-1 RNA titre at 50 copies per mL or above, including missing virological data within the time window (the Cochran-Mantel-Haenszel method, estimated treatment difference [ETD], 0.3%, 95% CI - 1.6 to 2.1), establishing the non-inferiority of ANV/3TC/TDF to EVG/Cobi/FTC/TAF. The proportions of participants experiencing at least one treatment-emergent adverse events (AEs) were comparable between the two arms (97.6% versus 97.6%). A small proportion of participants discontinued study drug due to AEs (0.3% versus 0.3%). Serious AEs occurred in 11 (2.9%) participants on ANV/3TC/TDF and 9 (2.4%) participants on EVG/Cobi/ FTC/TAF, respectively, none of which was considered related to study drug at the jurisdiction of the investigator. At week 48, participants on ANV/3TC/TDF showed a significantly fi cantly less weight gain from baseline compared to those on EVG/Cobi/FTC/TAF (least square mean, 1.16 versus 2.05 kg, ETD - 0.90 kg, 95% CI, - 1.43 to - 0.37). The changes in serum lipids from baseline also favoured ANV/3TC/TDF over EVG/Cobi/ FTC/TAF. Interpretation In virologically suppressed PLWH on previous NNRTI-based ARV regimen, switch to ANV/3TC/TDF resulted in less weight gain, and improved lipid metabolism while maintaining virological suppression non-inferior to that to EVG/Cobi/FTC/TAF.

IntroductionLittle is known about the first line induction chemotherapy cycles for HIV-associated diffuse large B-cell lymphoma (DLBCL) as these are less common than HIV-negative lymphoma. Currently, the optimal treatment cycles option remains undefined. Therefore, we performed a multi-center study to analyze the clinical characteristics and outcomes of HIV-associated DLBCL patients in different treatment modes in China.MethodsTotally 273 newly diagnosed HIV-associated DLBCL patients at eleven large academic centers from October 2008 to October 2021, were analyzed.ResultsIn the entire cohort, the median age was 47 years (range, 21-90) at lymphoma diagnosis, and 223 patients were male (81.7%). One hundred and ninety-four (71.1%) patients were germinal center B-cell-like lymphoma (GCB) subtype. Most patients (65.2%, 178/273) had elevated lactate dehydrogenase (LDH), and advanced Ann Arbor stage (78.9% 213/273) at diagnosis. High international prognostic index (IPI) score (3-5) at diagnosis was found in 65.2% (178/273) of patients. One hundred and fifty-five patients (56.8%) had extranodal involvement. The median CD4 cell count was 168/μl (range, 2-1067), of whom 174 (63.7%) had a CD4 cell count below 200/μl. The median follow‐up of our cohort was 10.1 (0.1-160) months. The overall 2-year OS rates 58.0%. Median OS times in the 0, 1-3, 4-6, and >6 cycles chemotherapy cohort were 7.1 months, 20.0 months, not reached, and not reached, respectively (Hazard Ratio (HR)=0.549, 95% Confidence interval (CI) 0.451-0.667; p<0.001). Cox multivariate analysis showed that age ≥60 (HR=2.207, 95%CI 1.321-3.690; p=0.003), high IPI score (3-5) (HR=2.926, 95% CI 1.716-4.988; p<0.001), B symptoms (HR=1.928, 95%CI 1.192-3.119; p=0.007), elevated LDH (HR=1.696, 95%CI 1.031-2.791; p=0.038) and received less than 4 cycles chemotherapy (HR=0.520, 95%CI 0.424-0.637; p<0.001) were independent risk factor for adverse prognosis based on overall survival (OS).DiscussionThese results demonstrated that 4-6 cycles chemotherapy were significantly associated with improved outcomes in HIV-associated DLBCL patients. However, >6 cycles chemotherapy did not further improve the survival of patients.

Background Despite the introduction of combined antiretroviral therapy, the clinical outcomes of HIV-associated Burkitt lymphoma (BL) remain poor. Methods To evaluate the clinical characteristics, prognostic factors, and outcomes of HIV-associated BL, we conducted a retrospective analysis of patients from multiple centers in China. Results The study included 41 patients from 8 medical centers. Among the included population, male patients accounted for 87.8%, with 75.6% in advanced stages. Notably, 46.3% of cases involved bone marrow, while 19.5% involved the central nervous system (CNS). The most commonly used chemotherapy regimen was DA-EPOCH ± R, accounting for 53.6% of cases. The overall response rates for patients receiving DA-EPOCH ± R and R-Hyper-CVAD were 59% and 58.2%, respectively. Interestingly, patients receiving regimens containing rituximab had similar complete remission rates (25% vs. 23.5%) and overall survival time (45.69 ± 11.58 vs. 47.79 ± 11.72 months, P = 0.907) compared to those without rituximab, but differed in progression rates (33.3% vs. 47.1%). For the entire cohort, the 1-year progression-free survival (PFS) and overall survival (OS) rates were 52% and 67%, respectively. CNS involvement was independent risk factors for survival, with 1-year PFS and OS rates of 0% and 38% for patients with CNS involvement, and PFS and OS rates of 66% and 75% for patients without CNS involvement. Conclusions HIV-associated BL patients in China have poor prognosis and show limited response to current treatment regimens. The absence of CNS involvement significantly improves clinical outcomes. The use of rituximab is not significantly associated with improved outcomes but can reduce disease progression.

Background Uterine cervical carcinoma is a severe health threat worldwide, especially in China. The International Federation of Gynecology and Obstetrics (FIGO) has revised the staging system, emphasizing the strength of magnetic resonance imaging (MRI). We aimed to investigate long-term prognostic factors for FIGO 2018 stage II–IIIC2r uterine cervical squamous cell carcinoma following definitive radiotherapy and establish a prognostic model using MRI-derived tumor volume. Methods Patients were restaged according to the FIGO 2018 staging system and randomly grouped into training and validation cohorts (7:3 ratio). Optimal cutoff values of squamous cell carcinoma antigen (SCC-Ag) and tumor volume derived from MRI were generated for the training cohort. A nomogram was constructed based on overall survival (OS) predictors, which were selected using univariate and multivariate analyses. The performance of the nomogram was validated and compared with the FIGO 2018 staging system. Risk stratification cutoff points were generated, and survival curves of low-risk and high-risk groups were compared. Results We enrolled 396 patients (training set, 277; validation set, 119). The SCC-Ag and MRI-derived tumor volume cutoff values were 11.5 ng/mL and 28.85 cm 3 , respectively. A nomogram was established based on significant prognostic factors, including SCC-Ag, poor differentiation, tumor volume, chemotherapy, and FIGO 2018 stage. Decision curve analysis indicated that the net benefits of our model were higher. The high-risk group had significantly shorter OS than the low-risk group in both the training ( p < 0.0001) and validation sets ( p = 0.00055). Conclusions Our nomogram predicted long-term outcomes of patients with FIGO 2018 stage II–IIIC2r uterine cervical squamous cell carcinoma. This tool can assist gynecologic oncologists and patients in treatment planning and prognosis.

BackgroundSleep disturbances are common in people living with Human Immunodeficiency Virus (HIV) and may lead to poor adherence to antiretroviral therapy and worsen HIV symptom severity. Due to the side effects of pharmacotherapy for sleep disturbances, there is more room for non-pharmacological interventions, but knowledge of how these non-pharmacological interventions have been used to improve sleep in people living with HIV (PLWH) is still missing.ObjectiveTo investigate the content of non-pharmacological interventions, sleep measurements, and the impact of these interventions on improving sleep in PLWH.MethodsFollowing PRISMA guidelines, we conducted a systematic search on PubMed, EMBASE, Cochrane Central Registry of Controlled Trials, Cumulative Index to Nursing and Allied Health Literature, Web of Science, China National Knowledge Infrastructure, Wanfang Data, and China Biology Medicine disc. Non-pharmacological interventions for improving sleep in PLWH were included, and study quality was assessed using the Joanna Briggs Institute (JBI) critical appraisal checklists. We performed a narrative approach to synthesize the data to better understand the details and complexity of the interventions.ResultsFifteen experimental studies in three categories for improving sleep in PLWH were included finally, including psychological interventions (components of cognitive-behavioral therapy for insomnia or mindfulness-based cognitive therapy, n = 6), physical interventions (auricular plaster therapy, acupuncture, and exercise, n = 8), and elemental interventions (speed of processing training with transcranial direct current stimulation, n = 1). Wrist actigraphy, sleep diary, and self-reported scales were used to measure sleep. Psychological interventions and physical interventions were found to have short-term effects on HIV-related sleep disturbances.ConclusionsPsychological and physical interventions of non-pharmacological interventions can potentially improve sleep in PLWH, and the combination of patient-reported outcomes and actigraphy devices can help measure sleep comprehensively. Future non-pharmacological interventions need to follow protocols with evidence-based dosing, contents, and measures to ensure their sustainable and significant effects.

Background People living with HIV (PLWH) carry a high risk for mental health problems, which has been extensively reported in the literature. However, an understanding of mental health characteristics in different subgroups of PLWH is still limited. In the present study, we conducted a cross-sectional survey to explore mental health characteristics and their associations with childhood trauma in two major subgroups of PLWH in China. Methods A total of 533 PLWH (213 prisoners in the prison system, and 320 outpatients) were assessed using the 8-item Positive Subscale of the Community Assessment of Psychic Experiences (CAPE-P8), Generalized Anxiety Disorder scale (GAD-7), Patient Health Questionnaire (PHQ-9), and Childhood Trauma Questionnaire (CTQ). Results From the total sample, 22.0% PLWH frequently experienced psychotic-like experiences (PLEs), 21.8% had clinically significant anxiety syndrome, 34.0% had clinically significant depressive syndrome, and 63.6% experienced at least one type of traumatic exposure during their childhood, with physical neglect being the most common. Compared to outpatients with HIV, prisoners living with HIV reported more severe mental health problems and a higher frequency of childhood trauma, with childhood trauma in turn predicting higher risk for mental health problems. Similarly, among outpatients living with HIV, both childhood emotional and sexual abuse had predictive effects on all the three mental health problems. Conclusions The study suggests that PLWH have higher risk of anxiety, depression and PLEs, and childhood trauma could serve as predicting factors for such risks. In addition, childhood trauma may play distinct roles in predicting the risk for the mental health problems, depending on different subgroup of PLWH.

Purpose Prophylactic intravenous nalbuphine was administered to observe its median effective dose (ED50) in reducing pain after undergoing laparoscopic total hysterectomy. To investigate the effect of different doses of nalbuphine on postoperative analgesia and adverse reactions in patients. Patients and Methods The 120 patients undergoing laparoscopic total hysterectomy were divided into 6 groups: group C (control) and group P (5 different doses of nalbuphine) with 20 patients per group. The doses of nalbuphine in group P were in an equally proportional series (groups P1, P2, P3, P4, and P5 received doses of 0.280, 0.200, 0.140, 0.100, and 0.070 mg/kg, respectively), diluted to 20 mL with saline and administered 5 min before the induction of anesthesia. A similar volume (20 mL) of saline was administered to group C 5 min before the induction of anesthesia. The numeric rating scale (NRS) of patients during awakening and after surgery, the number of postoperative salvage analgesia, and the occurrence of postoperative adverse effects were recorded. Results The ED50 (95% confidence interval (CI)) of nalbuphine in preventing pain during the awakening period in patients calculated using the point-slope method was 0.125 (0.108, 0.145) mg/kg. NRS scores differed among the 6 groups at 30 min and 1 h after extubation (P < 0.001; P < 0.001). Pairwise comparisons between groups revealed that, at 30 min after extubation, compared with group P1, the NRS scores of groups P4, P5, and C were higher (P = 0.001, P < 0.001, P < 0.001); compared with group P2, groups P5 and C had higher NRS scores (P = 0.011, P = 0.001). At 1 h after extubation, the NRS scores of groups P1 and P2 were lower than that of group P4 (P = 0.046, P = 0.036). Compared with the control, only the group P1 had a lower cough score (P = 0.009) and there were no differences in the other groups. There were no differences in sedation score at 10 min after extubation, the incidence of adverse events at 24 h postoperatively, or the number of remedial analgesics at 24 h postoperatively (P > 0.05). Conclusion The ED50 (95% CI) of nalbuphine as a prophylactic in reducing pain during recovery was 0.125 (0.108, 0.145) mg/kg. Compared with the control, nalbuphine at doses of 0.140, 0.200, and 0.280 mg/kg prevented pain during the awakening period. Among these doses, 0.280 mg/kg was determined to be the best, the occurrence of cough was less during extubation and the postoperative analgesic effect was good. However, it is necessary to pay attention to the occurrence of adverse reactions.

Epidemiological studies have repeatedly investigated the association between reduced pulmonary function and incident type 2 diabetes mellitus (T2DM). However, the results have been inconsistent. This meta-analysis aimed to clarify this association with prospective cohort studies. We searched PubMed, Web of Science (ISI), and Google Scholar for all studies (in English) reporting reduced lung function with a risk of T2DM. The measures of lung function included percentage of forced vital capacity for predicted values (FVC%pre), percentage of forced expiratory volume in the first second after expiration for predicted values (FEV1%pre) and FEV1-to-FVC ratio%. Summary risk ratios (RRs) and 95% confidence intervals (CIs) were calculated using fixed-effects or random-effects meta-analyses. A total of 5,480 incident T2DM patients among 88,799 individuals were identified from nine prospective cohort studies. Compared to the highest category of FVC%pre and FEV1%pre, the lowest category of FVC%pre and FEV1%pre were significantly associated with increased incident T2DM risk (FVC%pre: RR = 1.49, 95% CI: 1.39-1.59; FEV1%pre: RR = 1.52, 95% CI: 1.42-1.62). However, no significant relationship was found between the FEV1/FVC ratio and incident T2DM risk (RR = 1.01, 95% CI: 0.91-1.13). Current evidence suggests that restrictive rather than obstructive impairment of lung function is significantly associated with the incidence of T2DM. Further research is warranted to explore potential mediators of this relationship.

:Unfavorable fractures in sagittal split ramus osteotomy are hard to manage. The aim of this study is to develop a new classification method for unfavorable fractures of the proximal segment to guide clinical managements. After reviewing 964 cases of sagittal split ramus osteotomy, we found that the unfavorable fractures can be divided into 3 types: mandibular ramus transverse fractures (Type 1), bad fractures accompanied by free fragments (Type 2), and unexpected separation patterns without free fragments (Type 3). We calculated the incidence of each fracture type and provided instructions for their corresponding treatments. Thirty-six patients suffered from unfavorable fractures (7.4% of patients), among which 32 patients had unilateral fractures and 4 patients had bilateral fractures. There were 2 Type 1 fractures (0.2% of split sites), 8 Type 2 fractures (0.8% of split sites), and twenty-six Type 3 fractures (2.3% of split sites). Type 1 unfavorable fractures are difficult to deal with, but Types 2 and 3 are generally manageable and they have no significant impact on the final outcomes. The new classification can effectively guide treatment strategies for unfavorable fractures. Severe cases of unfavorable fractures are rare, and most unfavorable fracture cases have a positive prognosis if correctly treated in time.

There have been no prospective clinical studies investigating adherence and tolerability of HIV post-exposure prophylaxis (PEP) in China. Tolerability, adherence, and transmitted drug resistance are concerns, especially when single-tablet regimen (STR) usage is low. The present study aimed to explore the safety, tolerability, and adherence of regimens containing albuvirtide (ABT) compared with recommended non-STR antiretrovirals for HIV PEP. This was a prospective, open-label, multicenter cohort study. The subjects were stratified into 3 groups based on their preference: ABT + Dolutegravir (DTG) (Group 1), ABT + Tenofovir disoproxil fumarate (TDF) + Lamivudine (3TC) (Group 2), and DTG + TDF + 3TC (Group 3). All enrolled subjects received PEP within 72 h after exposure and continued for 28 days, and were followed-up for 12 weeks. A total of 330 participants were enrolled in the three groups. Most participants were male (87.2%). Sexual contact was the most frequent mode of exposure (91.9%). The average time from exposure to treatment was 26.8 ± 19.5 h. There were no statistically significant differences between the three study groups with respect to completion of oral medication at 28 days. The 28-day completion rate was shown to be significantly higher with ABT versus oral (88.9% vs. 64.0%; p < 0.0001), and adherence with ABT was 94.4% compared to 75.7% with oral PEP (p < 0.0001). Subjects in ABT-containing Group 1 exhibited higher adherence than those in Group 3 (87.3% vs. 72.9%; p < 0.05). None of the participants reported serious adverse drug reactions which led to withdrawal from the study. All the drug regimens were found to be safe and well tolerated. No HIV incident case was observed during the study period. ABT-containing regimens (ABT + DTG or ABT + TDF + 3TC) offer a good option for HIV PEP due to higher completion rates and adherence than the DTG + TDF + 3TC regimen. The overall safety was comparable and acceptable among the three groups. The study was registered in Chinese Clinical Trial Registry with registration number (ChiCTR1900022881, http://www.chictr.org.cn/showprojen.aspx?proj=37395 ).

Purpose: To present a nomogram to predict overall survival in patients with FIGO-2018 II to III squamous cell cervical carcinoma undergoing radical radiotherapy. Patients and Methods: Patients diagnosed with FIGO-2018 II to III squamous cell cervical cancer between December 2013 and December 2014 were analyzed retrospectively. The optimal cutoff point for tumor length and width were determined by R package. We identified prognostic factors by univariate and multivariate Cox proportional-hazard regression, then built a nomogram to visualize the prediction model. Our model was compared to the 2018 FIGO staging prediction model. Harrell's concordance index, receiver operating characteristic curve, calibration plot were used to evaluate the discriminability and accuracy of the predictive models, and decision curve analysis (DCA) was used to show the net benefits. Results: Data from 469 patients were included in the final analyses. The cutoff values of tumor length and width were 5.10 cm and 4.13 cm, respectively. Four independent prognostic variables-tumor length, tumor width, lower one-third vaginal involvement, and lymph node metastases-were used to establish the nomogram. The C-index of the nomogram was 0.71 (95%, CI = 0.66-0.77), which was better than that of the 2018 FIGO stage prediction model (C-index: 0.62, 95% CI = 0.58-0.66, p = 0.009). The calibration plot of the nomogram was a good fit for both 3-year and 5-year overall survival predictions. And DCA curves showed that net benefits for our model were higher than FIGO-2018 staging system. Conclusion: A clinically useful nomogram for calculating overall survival probability in FIGO-2018 II to III squamous cell cervical cancer patients who had received radical radiotherapy was developed. Tumor length, tumor width, lower one-third vaginal involvement, and lymph node metastases were found to be independent prognostic factors. Our model performed better than the 2018 FIGO staging model. The findings could help clinicians in China to predict the survival of these patients in clinical care and research.

Background: Sepsis patients with insufficient tissue perfusion and hypoxia should be identified and resuscitated immediately. Recently, venous‐to‐arterial carbon dioxide pressure changes and the arteriovenous oxygen content difference ratio (Pcv‐aCO2/Ca‐vO2) as a predictor of tissue perfusion recovery and poor prognosis. Objectives: Pcv‐aCO2/Ca‐vO2 is a substitute for respiratory entropy, the elevation of which indicates a lack of tissue perfusion. Pcv‐aCO2/Ca‐vO2 can be used as an indicator to predict the prognosis of patients with sepsis or septic shock, but its prognostic value has not been fully evaluated. Here, we have performed a meta‐analysis to assess its predictive value for mortality. Methods: Meta‐analysis of Observational Studies in Epidemiology group guidelines were followed for this meta‐analysis. We searched the comprehensive electronic databases of PubMed, EMBASE, Web of Science, and Cochrane libraries from inception to March 2019, using the terms including “venous‐arterial,” “carbon dioxide,” “Shock, Septic,” and related keywords. The Newcastle‐Ottawa scale was used for quality evaluation of the literature. A meta‐analysis was performed using RevMan 5.3 and Stata 14.0 software to evaluate the effects of Pcv‐aCO2/Ca‐vO2 on short‐term mortality, sequential organ failure assessment, and acute physiology and chronic health evaluation scores in patients with sepsis or septic shock. Results: The final analysis included 13 clinical studies involving a total of 940 subjects. The results of the meta‐analysis showed that non‐surviving patients had higher Pcv‐aCO2/Ca‐vO2 than survivors after fluid resuscitation (standardized mean difference = 0.68, 95% confidence interval = 0.24–1.12) and blood samples taken 6 h after resuscitation showed a greater risk of mortality (risk ratio = 1.89, 95% confidence interval = 1.48–2.41) and sequential organ failure assessment scores (mean difference = 1.58, 95% confidence interval = 0.88–2.28, P < 0.01) in patients with high Pcv‐aCO2/Ca‐vO2. These differences were statistically significant. Conclusion: This meta‐analysis indicates that Pcv‐aCO2/Ca‐vO2 has predictive value for mortality in patients with sepsis or septic shock. Further studies are now required to determine the optimal threshold for predicting sepsis mortality.

BACKGROUND: The intraoperative 15° left-tilt position during cesarean delivery has more recently been questioned regarding its effect on fetal acid-base balance and is a frequent source of complaints by surgeons. We hypothesized that a 30° left-tilt position during surgical preparation could improve the acid-base balance of the fetus compared with the 15° left-tilt or supine position during surgical preparation. METHODS: Women undergoing elective cesarean delivery under combined spinal epidural anesthesia were randomized to a supine position, 15° left-lateral tilt position or 30° left-lateral tilt position; the position was changed to supine before the incision. Anesthetic management was standardized and included fluid loading with 10 mL/kg of normal saline followed by colloid loading. Hypotension (systolic blood pressure [SBP] reduction >20% baseline value or SBP <90 mm Hg) was treated with boluses of phenylephrine or ephedrine according to maternal heart rate. The primary outcome was umbilical arterial blood pH and the secondary outcomes included maternal SBP within 15 minutes after induction of anesthesia, the amount of vasoactive drug administered before end of the surgery, and the incidence of hypotension during cesarean delivery. RESULTS: Seventy-five patients were included. After testing by analysis of variance, there was no significant difference in the umbilical arterial pH among the 3 groups (supine group: 7.31 ± 0.03 vs 15° group: 7.30 ± 0.04 vs 30° group: 7.31 ± 0.02, P = .28). The 30° group required significantly less phenylephrine (P = .007) and ephedrine (P = .005) before the end of surgery than the supine group; however, the only benefit observed in the 15° group was that the mean SBP at 3 minutes after spinal injection was significantly improved compared with the supine group. CONCLUSIONS: Compared with the supine position, the 30° left-tilt position during surgical preparation did not significantly improve the fetal acid-base status, but it significantly reduced the use of phenylephrine and ephedrine and reduced the incidence of hypotension; however, these benefits were not observed in the 15° left-tilt group.

Background: The Pittsburgh Sleep Quality Index (PSQI) has been a widely used instrument measuring sleep quality among people living with HIV (PLWH) in China while its psychometric properties have yet to be examined in this population. We aimed to assess the reliability and validity of the Chinese version of PSQI in PLWH and identify factors associated with sleep quality. Methods: This study was based on a longitudinal study of newly diagnosed PLWH, among whom the PSQI was used to measure sleep quality 5 years after HIV diagnosis (n = 386). To evaluate internal consistency, Cronbach's alpha and corrected item-total correlation were calculated. To assess construct validity, Pearson's correlation coefficients were calculated between PSQI scores and depression, anxiety, stress, and health-related quality of life (HRQoL). Known group validity was evaluated by comparing PSQI scores between participants with probable depression and those without. Binary logistic regression was conducted to identify factors associated with sleep disturbances. Results: The internal consistency Cronbach's alpha for the Chinese version of PSQI in PLWH was 0.713. Construct validity was established by significant relationships between PSQI and depression, anxiety, stress, and HRQoL. The PSQI scores in participants with probable depression were significantly higher than those without, indicating good known-group validity. Sleep disturbances were associated with less income, higher CD4 counts, antiretroviral treatment (ART) initiation, exercise, depression, and higher stress levels. Conclusions: The Chinese version of PSQI is feasible for use among Chinese PLWH. Over a third of PLWH reported sleep disturbances. More attention should be given to individuals with less income and on ART. Intervention aimed at improving mental health or facilitating exercise may improve sleep quality.
