Relationships among Sleep Time, Physical Activity Time, Screen Time, and Nutrition Literacy of Adolescents: A Cross-Sectional Study in Chongqing, China.

Background: Unhealthy lifestyles among adolescents are reaching alarming levels and have become a major public health problem. This study aimed to assess the relationship between sleep time, physical activity (PA) time, screen time (ST), and nutritional literacy (NL). Methods: This cross-sectional online study involving adolescents aged 10-18 years was conducted in September 2020 in 239 schools in Chongqing, China. NL was measured using the "Nutrition Literacy Scale for middle school students in Chongqing (CM-NLS)". According to the recommended by the Chinese dietary guidelines (2022), we divided the sleep time of junior high school students into <9 h and ≥9 h, high school students into <8 h and ≥8 h, divided the workdays into weekend PA time < 1 h and ≥1 h, and divided the workdays into weekend ST < 2 h and ≥2 h. The multinomial logistic regression model was used to examine the association. Results: A total of 18,660 adolescents (50.2% males) were included. The proportion of participants that were junior high school students and attended boarding schools was 57.2% and 65.3%, respectively. Compared with senior high school students, junior high school students had a higher level of NL. Whether on workdays or weekends, participants with sleep time ≥ 8/9 h, PA time ≥ 1 h, and ST < 2 h per day had higher levels of NL. On weekdays, participants who met the sleep time ≥ 8 h/9 h (OR = 1.48, 95% CI: 1.36, 1.62) and PA time ≥ 1 h (OR = 1.69, 95% CI: 1.59, 1.81) had higher reporting of NL levels. Conclusions: Sleep time, PA time, and ST were positively correlated with NL among adolescents, especially junior high school students.

A GP130-Targeting Small Molecule, LMT-28, Reduces LPS-Induced Bone Resorption around Implants in Diabetic Models by Inhibiting IL-6/GP130/JAK2/STAT3 Signaling.

In this study, we examined the effect of the GP130-targeting molecule, LMT-28, on lipopolysaccharide- (LPS-) induced bone resorption around implants in diabetic models using in vitro and rat animal experiments. First, LMT-28 was added to osteoblasts stimulated by LPS and advanced glycation end products (AGEs), and nuclear factor-κB receptor-activating factor ligand (RANKL) and associated pathways were evaluated. Then, LMT-28 was administered by gavage at 0.23 mg/kg once every 5 days for 2 weeks to type 2 diabetic rats with peri-implantitis induced by LPS injection and silk ligature. The expression of IL-6 and RANKL was evaluated by immunohistochemistry, and the bone resorption around implants was evaluated by microcomputed tomography. The results showed that LMT-28 downregulated the expression of RANKL through the JAK2/STAT3 signaling pathway in osteoblasts stimulated by LPS and AGEs, reduced bone resorption around implants with peri-implantitis, decreased the expression of IL-6 and RANKL, and decreased osteoclast activity in type 2 diabetic rats. This study confirmed the ability of LMT-28 to reduce LPS-induced bone resorption around implants in diabetic rats.

Conservative Binary Dynamics with a Spinning Black Hole at O(G

We compute the conservative two-body Hamiltonian of a compact binary system with a spinning black hole through O(G^{3}) to all orders in velocity, including linear and quadratic spin terms. To obtain our results we calculate the classical limit of the two-loop amplitude for the scattering of a massive scalar particle with a massive spin-1 particle minimally coupled to gravity. We employ modern scattering amplitude and loop integration techniques, in particular numerical unitarity, integration-by-parts identities, and the method of regions. The conservative potential in terms of rest-frame spin vectors is extracted by matching to a nonrelativistic effective field theory. We also apply the Kosower-Maybee-O'Connell (KMOC) formalism to calculate the impulse in the covariant spin formalism directly from the amplitude. We work systematically in conventional dimensional regularization and explicitly evaluate all divergent integrals that appear in full- and effective-theory amplitudes, as well as in the phase-space integrals that arise in the KMOC formalism.

A novel antibiotic combination of linezolid and polymyxin B octapeptide PBOP against clinical Pseudomonas aeruginosa strains.

BACKGROUND: Antibiotic-resistant Gram-negative bacteria are becoming a major public health threat such as the important opportunistic pathogen Pseudomonas aeruginosa (P. aeruginosa). The present study investigated enhancement of the linezolid spectrum, which is normally used to treat Gram-positive bacteria, at inhibiting P. aeruginosa growth. METHODS: The checkerboard test or time-kill assay were carried out to determine the antibacterial effects of linezolid in cooperation with polymyxin B octapeptide PBOP (LP) against P. aeruginosa based on in vitro model. The protective effect of LP against P. aeruginosa infection was assessed based on a Caenorhabditis elegans (C. elegans) model. RESULTS: The synergistic activity and antibacterial effects were significantly increased against P. aeruginosa by LP treatment, while linezolid and PBOP as monotherapies exhibited no remarkably bactericidal activity against the clinical strains. Additionally, LP treatment modified biofilm production, morphology, swimming motility of P. aeruginosa, and protected C. elegans from P. aeruginosa infection. CONCLUSIONS: This research demonstrates that LP combination has significant synergistic activity against P. aeruginosa, and PBOP is potential to be an activity enhancer. Notably, this strategy improved the antibacterial activity spectrum of linezolid and other anti-Gram-positive agents and represents an effective choice to surmount the antibiotic resistance of bacteria in the long term.

Association between Selenium Status and Chronic Kidney Disease in Middle-Aged and Older Chinese Based on CHNS Data.

BACKGROUND: The association between selenium and chronic kidney disease (CKD) remains controversial. Population studies with large samples facilitate the reliability of conclusions. OBJECTIVE: In this study, we aimed to describe the prevalence of a CKD association with selenium intake in middle-aged and older Chinese. METHODS: Data for this study were obtained from the China Health and Nutrition Survey (CHNS). A total of 5381 participants (aged ≥ 45) with biochemical test data were included in the study. Logistic regression models were used to examine the association between diet selenium intake (quartile) and the prevalence of CKD. RESULTS: A total of 942 (17.01%) participants had CKD. The prevalence of CKD was 23.33%, 20.32%, 14.98%, and 9.25% among participants with average selenium intakes of 21.5 ± 4.82, 33.1 ± 2.79, 43.8 ± 3.70, and 67.0 ± 13.97 µg/day, respectively. In the fully adjusted model (Model 3), across the quartiles of selenium intake, the ORs for the prevalence of CKD were 1.00, 1.09 (95% CI 0.69-1.73), 0.82 (95% CI 0.49-1.38), and 0.43 (95% CI 0.22-0.85). The protein intake had a certain diagnostic significance for the selenium intake. CONCLUSIONS: An adequate selenium intake may have a positive effect on CKD. The influence of individual weight and location on the effect of selenium on CKD needs to be further explored.

Development of Nutrition Literacy Scale for Middle School Students in Chongqing, China: A Cross-Sectional Study.

Background: Information on nutrition literacy of middle schoolers is limited and tools for measuring nutrition literacy of middle schoolers are inadequate. Nutrition literacy has a positive effect on health. Improving children's nutrition literacy can help them to master the necessary nutritional knowledge, develop a healthy lifestyle, and learn to supplement nutrition according to their own needs for healthy growth. Objectives: To develop the Chongqing Middle school student Nutrition Literacy Scale (CM-NLS). Methods: Three experiments were conducted. A theoretical framework and an initial item pool of CM-NLS were established based on the literature review. And the two-round Delphi method was used to explore the suitable acceptance indicators and items. Item evaluation and reduction were performed using the classical test theory. Then, the items in the final CM-NLS were tested for their validity and reliability amongst 462 middle school students. The construct validity was assessed using exploratory factor analysis (EFA) and confirmatory factor analysis (CFA). The internal consistency reliability and split-half reliability were evaluated using Cronbach's alpha coefficients. Results: The final CM-NLS consisting of 52 items that were based on three primary items (functional, interactive and critical) and six sub-items (obtain, understand, apply, interact, medial literacy and critical skill) was developed and validated. EFA suggested six factors explaining 69.44% of the total variance (Kaiser-Meyer-Olkin test = 0.916, Bartlett's test χ2 = 5,854.037, P < 0.001). CFA showed that the model fit the data adequately, with χ2/df = 1.911, root mean square error of approximation = 0.063, goodness-of-fit index = 0.822 and adjusted goodness of fit index = 0.790. The total CM-NLS Cronbach's alpha values of internal consistency and split-half reliability were 0.849 and 0.521, respectively, with reasonable reliability. Conclusions: CM-NLS is a valid and reliable instrument for assessing nutrition literacy among middle school students in Chongqing. Specifically, it could be used by practitioners for needs assessment before the implementation of a nutrition education program.

Association Between Nutrition Literacy and Overweight/Obesity of Adolescents: A Cross-Sectional Study in Chongqing, China.

Objective: The burden of overweight and obesity in adolescents is increasing rapidly. This study aimed to assess the association between nutrition literacy and overweight/obesity among adolescents in China. Methods: This cross-sectional online study involving adolescents aged 10-18 years was conducted in September 2020 in 239 schools in Chongqing China. Overweight and obese adolescents were determined based on the International Obesity Task Force's recommended age-sex specific body mass index cutoff points. Nutrition literacy was measured using the "Nutrition literacy scale for middle school students in Chongqing (CM-NLS)." The CM-NLS included three subdomains (functional nutritional literacy, interactive nutrition literacy, and critical nutrition literacy). Multinomial logistic regression model was used to examine the association. Results: A total of 18,176 adolescents (49.8% girls) were included. The prevalence of overweight and obesity was 9.6% and 17.0%, respectively. Compared with those having a low nutrition literacy score (below median), those with a high score were less likely to be overweight and obese. The odds ratio (95% CI) for overweight was 0.87 (0.79-0.97) (nutrition literacy) and 0.81 (0.73-0.90) (functional nutritional literacy). The corresponding figures for obesity were 0.84 (0.77-0.91) and 0.73 (0.67-0.80), respectively. Significant interaction existed between grade and nutrition literacy. The inverse association between nutrition literacy and overweight/obesity was significant among those in senior school but not among those in junior high school. Conclusion: Nutrition literacy was inversely associated with overweight/obesity among adolescents, especially those attending senior high schools.

Scattering Amplitudes, the Tail Effect, and Conservative Binary Dynamics at O(G

We complete the calculation of conservative two-body scattering dynamics at fourth post-Minkowskian order, i.e., O(G^{4}) and all orders in velocity, including radiative contributions corresponding to the tail effect in general relativity. As in previous calculations, we harness powerful tools from the modern scattering amplitudes program including generalized unitarity, the double copy, and advanced multiloop integration methods, in combination with effective field theory. The classical amplitude involves complete elliptic integrals, and polylogarithms with up to transcendental weight 2. Using the amplitude-action relation, we obtain the radial action directly from the amplitude, and match the known overlapping terms in the post-Newtonian expansion.

Nutrition Literacy of Middle School Students and Its Influencing Factors: A Cross-Sectional Study in Chongqing, China.

Nutrition literacy plays an important role in children's dietary habits and nutrition. This study aimed to analyse the status of nutrition literacy and its influencing factors amongst middle school students in Chongqing, China. "Nutrition literacy scale for middle school students in Chongqing" was used in 29 districts of Chongqing in September 2020. The scores of nutrition literacy and its' three sub-domains (functional, interactive and critical nutrition literacy) were divided into low and high groups based on their median scores. Binary logistic regression was used to measure the influencing factors of nutrition literacy. A total of 18,660 middle school students were included in this study. The median of nutrition literacy of middle school students was 61.68 (IQR = 14.37). Interactive nutrition literacy had the highest score (median = 70.00, IQR = 20.00), followed by functional nutrition literacy (median = 68.69, IQR = 14.14) and critical nutrition literacy (median = 45.83, IQR = 25.00). Students who were the minority (OR = 0.71, 95% CI = 0.637-0.785), in senior high school (OR = 0.51, 95% CI = 0.477-0.548), in rural areas (OR = 0.85, 95% CI = 0.790-0.911), receiving school meal support from the government (OR = 0.63, 95% CI = 0.591-0.664), with other caregivers' parenting (OR = 0.86, 95% CI = 0.805-0.914), with parents having a low level of education and with an abnormal BMI [thin (OR = 0.91, 95% CI = 0.837-0.990), overweight (OR = 0.87, 95% CI = 0.785-0.968), and obese (OR = 0.83, 95% CI = 0.767-0.902)] presented less probability of being a high level of nutrition literacy. Our results could assist public health authorities in developing strategies of nutrition literacy promotion for references and theoretical foundations.

Highly Effective Activated Carbon-Supported Ni-Mn Bifunctional Catalyst for Selective Hydrodeoxygenation of 5-Hydroxymethylfurfural to 2,5-Dimethylfuran.

Designing highly efficient and low-cost catalysts for conversion of renewable biomass into high value-added chemicals and biofuels is important and challenging. Herein, a non-noble Ni-Mn bifunctional catalyst supported on activated carbon (Ni-Mn/AC) was developed by an incipient wetness impregnation method. The catalyst was found to be economic and efficient for the selective hydrodeoxygenation of biomass-derived 5-hydroxymethylfurfural (5-HMF) to 2,5-dimethylfuran (2,5-DMF). The optimal Ni-Mn/AC (Ni/Mn=3) catalyst achieved 98.5 % 2,5-DMF yield with 100 % conversion of 5-HMF under mild reaction conditions of 180 °C, 2.0 MPa H2 for 4 h. Furthermore, the catalyst exhibited outstanding reusability and could be recycled eight times without loss of activity. The addition of Mn not only enhanced the reactivity of 5-HMF but also resulted in the dominant reaction pathway shift from the hydrogenation of the C=O bond to the hydrogenolysis of C-OH bond, which was attributed to the synergy of highly dispersed Ni metallic nanoparticles and moderate Lewis acid sites from MnOx as revealed by detailed characterizations.

Geraniin as a potential inhibitor of SARS-CoV-2 3CLpro.

Geraniin is a polyphenolic compound first isolated from Geranium thunbergii. The major protease (Mpro), namely 3 C-like protease (3CLpro), of coronaviruses is considered an attractive drug target as it is essential for the processing and maturation of viral polyproteins. Thus, our primary goal is to explore the efficiency of geraniin on 3CLpro of SARS-CoV-2 using the computational biology strategy. In this work, we studied the anti-coronavirus effect of geraniin in vitro and its potential inhibitory mode against the 3CLpro of SARS-CoV-2. We found that geraniin inhibited HCoV-OC43 coronavirus-infected cells during the attachment and penetration phases. Molecular docking and dynamics simulations exhibited that geraniin had a strong binding affinity and high stable binding to 3CLpro of SARS-CoV-2. Geraniin showed a strong inhibitory activity on coronavirus and may be a potential inhibitor of SARS-CoV-2 3CLpro.

Impact of intraoperative intravenous magnesium on spine surgery: A systematic review and meta-analysis of randomized controlled trials.

BACKGROUND: The effectiveness and safety of intraoperative intravenous magnesium (IIM) on spine surgery remain uncertain, as recent randomized controlled trials (RCTs) yielded conflicting results. The purpose of this study was to determine the impact of IIM on spine surgery. METHODS: A literature search was performed on multiple electronic databases, ClinicalTrial.gov and Google Scholar on July 12th 2021, and reference lists were examined. We selected RCTs comparing the effects of IIM with placebo treatment on spine surgery. We calculated pooled standard mean difference (SMD) or risk ratio (RR) with 95% confident interval (CI) under a random-effect model. We assessed risk of bias using Cochrane risk-of-bias tool and Jadad score was applied to assess the quality of each included trial. Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) was used to determine the confidence in effect estimates. Sensitivity analysis was conducted by omitting each included study one by one from the pooled analysis. PROSPERO Registration: CRD42021266170. FINDINGS: Fourteen trials of 781 participants were included. Low- to moderate-quality evidence suggested that IIM reduces postoperative morphine consumption at 24 h (SMD: -1·61 mg, 95% CI: -2·63 to -0·58) and intraoperative remifentanil requirement (SMD: -2·09 ug/h, 95% CI: -3·38 to -0·81). High-quality evidence suggested that IIM reduces the risk of postoperative nausea and vomiting compared with placebo (RR: 0·43, 95% CI: 0·26 to 0·71). Besides, moderate-quality evidence suggested that recovery orientation time in the IIM group is longer than control group (SMD: 1·13 min, 95% CI: 0·83 to 1·43). INTERPRETATION: IIM as adjuvant analgesics showed overall benefits on spine surgery in terms of reducing analgesic requirement and postoperative nausea and vomiting; however, potential risks of IIM, such as delayed anesthetic awakening, should not be ignored. Future evidence will inform the optimal strategy of IIM administration for patients undergoing spine surgery. FUNDING: This study was funded by Beijing Municipal Natural Science Foundation (Grant No :7212117).

Comparison of sleep quality among puerperal women before and during the COVID-19 pandemic: a cross-sectional survey in Lanzhou, China.

PURPOSE: Few studies have yet examined sleep quality among puerperal women during the coronavirus disease 2019 (COVID-19) pandemic. This cross-sectional study aimed to compare the sleep quality of puerperal women before and during the COVID-19 pandemic in Lanzhou, China. The study exploreed the factors that affect sleep quality among puerperal women. METHODS: The study population comprised puerperal women who went to the obstetric department of the Gansu Provincial Maternity and Childcare Hospital on the 42nd day after childbirth. Sleep quality was measured using the Pittsburgh Sleep Quality Index (PSQI). Data were collected by doctors in the obstetric department before the COVID-19 pandemic (Oct.-Dec. 2019) and during the COVID-19 pandemic (Feb.-Apr. 2020) in China. Multiple linear regressions were used to examine the association between the sleep quality of puerperal women and COVID-19 and to identify factors that affect the total PSQI scores. RESULTS: In 2019, 546 puerperal women were assessed compared with 655 who were assessed in 2020. Compared with before COVID-19, the total PSQI scores of puerperal women improved during the COVID-19 pandemic. In addition, the influencing factors of sleep quality among puerperal women were the pandemic itself, age, conception method, and postpartum depression (PPD). CONCLUSIONS: In contrast with other studies, there was no evidence for worsening sleep quality of puerperal women during the COVID-19 pandemic in Lanzhou, China. Puerperal women who underwent assisted pregnancy or developed PPD were more likely to experience poor sleep quality.

Influence of soybean isolate on the formation of heterocyclic aromatic amines in roasted pork and its possible mechanism.

In this paper, the effects of soybean protein isolate (SPI) on the formations of five heterocyclic aromatic amines (HAAs) in roasted pork were investigated. The levels of all five HAAs improved upon addition of 2.5% of SPI (P < 0.05). With higher SPI dosage, the levels of HAA decreased after seeing an increase. Two HAAs (MeIQx and 4,8-DiMeIQx) were inhibited by 10.0% of SPI, with the inhibitory efficiencies of 7.0 % and 85.7%, respectively. After being heated, the levels of both the free amino acids and carbonyl groups in the SPI were observed significantly increased, from 55.04 µg g·SPI-1 to 91.66 µg g·SPI-1 and from 123.85 ± 13.07 to 931.78 ± 32.56, respectively (P < 0.05). Therefore, the possible promotion mechanism of the SPI was speculated that the heated SPI would provide both the HAA precursors and carbonyls, which significantly promoted the Strecker degradation and generated more HAA intermediates (P < 0.05).

Nutritional literacy and influencing factors among students from Nutrition Improvement Program for Rural Compulsory Education Students in Chongqing / 中国学校卫生

Objective@#To analyze the nutritional literacy and influencing factors among students from Nutrition Improvement Program for Rural Compulsory Education Students (NIPRCES) in Chongqing, and to provide a scientific basis for improving the nutritional literacy of middle school students in the NIPRCES.@*Methods@#Using cross sectional survey, a total of 3 365 students in the grade 7 and 8 were selected from the middle schools in 12 national pilot districts and 2 Chongqing pilot districts by online survey in September 2020. Students filled out a self designed nutritional literacy questionnaire anonymously. The relative evaluation method was used to convert the nutritional literacy of scores into a percentile, and the median score was used as the criterion for qualified nutritional literacy screening.@*Results@#The median score of nutritional literacy of participants was 63.5, and 64.2% achieved the qualified level. The results of multivariate Logistic regression analysis showed that boarding school ( OR =1.28, 95% CI =1.08- 1.51 ) and no parents as the primary caregiver ( OR =1.22，95% CI =1.05-1.42) were associated with poor nutritional literacy. Urban residence ( OR =0.75, 95% CI =0.63-0.90), NIPRCES local pilot ( OR =0.83, 95% CI =0.71-0.97) and high paternal education ( OR =0.70, 95% CI =0.52-0.95) were associated with higher nutritional literacy ( P <0.01). Classroom was the main channel for students to obtain nutrition information at present (65.1%) and in the future (72.8%).@*Conclusion@#The nutritional literacy among students in the NIPRCES in Chongqing needs to be improved. Nutritional literacy level of students can be strengthened by nutritional education in boarding schools, rural areas, national pilot areas, and primary caregivers.

Prevalence of anxiety and its associated factors among infertile patients after 'two-child' policy in Chongqing, China: a cross-sectional study.

BACKGROUND: With the prevalence of infertility increasing every year around the world, it has seriously impacted the individual quality of family and social life. Anxiety is one of the most prevalent anxiety disorders among infertile patients. After the two-child policy, whether it affected the prevalence of anxiety is controversial. This study aimed to determine the prevalence of anxiety and its potential risk factors among Chinese infertile women after the enforcement of 'two-child policy'. METHODS: This cross-sectional study included 693 infertile patients in a reproductive medical center in Chongqing, China, between February 2016 and December 2018. Data was collected by Self-filling questionnaires including basic demographic information and the Generalized Anxiety Disorder-7 (GAD-7). SPSS statistical software (IBM SPSS version 25) was used to analyse the obtained data. Descriptive analysis was used to describe basic information and anxiety scores, the chi-square test and binary logistic regression were used to analyse the relationship between anxiety and other variables. RESULTS: The prevalence of anxiety among total infertile patients was 21.8%, and its 23.5% among first-child infertile patients (FI), and 18.4% among second-child infertile patients (SI) respectively (P > 0.05). Binary logistic regression showed that patients with lower education levels were more likely to have anxiety (P < 0.01). Patients with middle salary incomes were more likely to have anxiety (OR = 1.860, 95% CI: 1.068-3.238). Oral contraception taking history (OR = 1.778, 95% CI: 1.186-2.667), and history of allergy (OR = 2.098, 95% CI: 1.219-3.612) were associated with anxiety. CONCLUSIONS: Under the full liberalization of the "two-child policy", the total prevalence of anxiety among Chinese infertile female is comparatively high. Low education levels, middle incomes, oral contraception taking and allergy history can be the related risk factors of anxiety. We promote that all infertile patients should be evaluated for the prevalence of anxiety, especially those with potential risks, and receive consultant or targeted treatment when needed.

The Effect of Erector Spinae Plane Blockade on Prevention of Postherpetic Neuralgia in Elderly Patients: A Randomized Double-blind Placebo-controlled Trial.

BACKGROUND: Postherpetic neuralgia (PHN) is the most common chronic complication following the onset of herpes zoster (HZ). Both the incidence of HZ and the proportion of patients with HZ who develop PHN rise with age. Ultrasound-guided erector spinae plane blockade (ESPB) has been reported to relieve neuropathic pain and PHN in elderly patients, but no randomized controlled trials have been conducted regarding the effect of ESPB on elderly patients with HZ in the acute or subacute phases. OBJECTIVES: To evaluate the effect of repeated ESPB on the occurrence of PHN in elderly patients with acute or  subacute HZ. STUDY DESIGN: A randomized double blind placebo-controlled trial with 2 parallel groups. SETTING: A university hospital in China. METHODS: Patients diagnosed with acute or subacute HZ were randomized to receive either ultrasound-guided ESPB (the ESPB group) or placebo subcutaneous injection (the control group) every 24 hours for 3 days. Patients were followed up at 12 weeks after the final treatment. The primary end point was the incidence of PHN at 12 weeks. RESULTS: A total of 52 patients were enrolled and randomized; 50 completed 12 weeks of follow-up. The incidence of PHN at 12 weeks was significantly lower in the ESPB group (15.4% [4/26]) than in the control group (41.7% [10/24]); relative risk 0.37, 95% confidence interval 0.13-1.02, P = 0.039. At 12 weeks, the VAS scores at rest and the total scores from the Short-Form McGill Pain Questionnaire-2 were significantly decreased in the ESPB group (P = 0.046 and P = 0.001, respectively). The incidence of neuropathic pain, sleep disturbance, and anxiety/depression were significantly reduced in the ESPB group (P = 0.002, P = 0.002, and P = 0.025, respectively). Patients using tramadol and hypnotics as well as total complications with oral medicines were remarkably decreased in the ESPB group (P = 0.008, P = 0.002, and P = 0.042 respectively). The adverse events during or after the procedure were comparable between the groups. LIMITATIONS: This trial was carried out in a single center with a 12-week follow-up. Nearly 8% of patients in the control group were lost to follow-up. CONCLUSIONS: For elderly patients suffering acute or subacute HZ, ESPB reduces the incidence of PHN at 12 weeks after treatment; it also decreases the occurrence of neuropathic pain, sleep disturbance, and anxiety/depression.

Gravitational Bremsstrahlung from Reverse Unitarity.

We compute the total radiated momentum carried by gravitational waves during the scattering of two spinless black holes at the lowest order in Newton's constant, O(G^{3}), and all orders in velocity. By analytic continuation into the bound state regime, we obtain the O(G^{3}) energy loss in elliptic orbits. This provides an essential step toward the complete understanding of the third-post-Minkowskian binary dynamics. We employ the formalism of Kosower, Maybee, and O'Connell (KMOC), which relates classical observables to quantum scattering amplitudes, and derive the relevant integrands using generalized unitarity. The subsequent phase-space integrations are performed via the reverse unitarity method familiar from collider physics, using differential equations to obtain the exact velocity dependence from near-static boundary conditions.

Influence of the request and purchase of television advertised foods on dietary intake and obesity among children in China.

BACKGROUND: This study aims to examine the effects of the request and purchase of Television (TV) advertised foods on children's dietary intake, overweight and obesity in China. METHODS: Data from 1417 children (aged 6-17 years) in the 2011 China Health and Nutrition Survey were analysed. The request and purchase of TV advertised foods were assessed through the frequency of children's requests to purchase TV advertised foods and the frequency of parents' purchases of these advertised foods, as well as the frequency of children's purchases of TV advertised foods. The height and weight of children were measured. Logistic regression models were used to identify the associations between the request and purchase of TV advertised foods and overweight/obesity of children. RESULTS: The request and purchase of TV advertised foods were positively associated with children's dietary intake of energy, protein, fat and carbohydrates. After adjusting for potential confounding factors, children's request and purchase of TV advertised foods and parent's purchase of TV advertised foods were positively associated with children's overweight/obesity: odds ratio (OR) and 95% confidence interval (CI) for overweight/obesity were: 1.46 (1.01-2.11) for children purchasing advertised foods ≥1 time/week, 1.59 (1.15-2.18) for parents purchasing advertised foods for their children ≥1 time/week and 1.39 (1.00-1.95) for children requesting advertised foods ≥1 time/week. CONCLUSIONS: The request and purchase of TV advertised foods are associated with children's dietary intake. Moreover, the request and purchase of TV advertised foods can increase the risk of overweight and obesity of children. Health education involving children's request and purchase of TV advertised foods and parents' purchase of TV advertised foods should be considered in China.

Puerarin reduces impairment of intestinal and adipose immune responses to influenza virus infection in mice.

Influenza is an acute viral respiratory disease that can also cause gastroenteritis-like symptoms, such as abdominal pain, nausea, vomiting, and diarrhea. Immune dysfunction of adipose tissue is involved in the occurrence and prognosis of influenza viral pneumonia. In this study, we analyzed intestinal and adipose immune responses in mice infected with influenza virus and found that the impairment of intestinal and adipose immunity to influenza virus infection could be reversed by treatment with puerarin, a medicinal compound isolated from Pueraria lobata (called "gegen" in Chinese). We found that the lungs, small intestines (duodenum, ileum, jejunum) and large intestines (colon and rectum) of infected mice showed obvious inflammatory lesions, with significantly increased levels of virus, inflammatory cytokines (interleukin [IL]-6, IL-17, and tumor necrosis factor-α), Toll-like receptors 3, 4, and 9, and integrin αvß3 and α4, and a decreased level of secreted IgA compared to the normal control group (NC) (P < 0.05-0.001). Influenza virus infected mesenteric lymph nodes and adipose tissue, and adipokines (leptin, visfatin, "chemerin", and adiponectin) of lung and mesenteric adipose tissue were dysregulated. Puerarin treatment reversed the impairment of the intestinal and adipose immune responses in mice infected with influenza virus. Our findings suggest that influenza virus can infect adipose tissue and lead to intestinal adipose immune dysfunction in normal-weight mice and that the impairment of the intestinal and adipose immune response to influenza virus infection can be reversed by puerarin treatment.
