Attenuated associations between increasing bmi and unfavorable lipid profiles in chinese buddhist vegetarians. Asia

Obesity is related to hyperlipidemia and risk of cardiovascular disease. Health benefits of vegetarian diets have well-documented in the Western countries where both obesity and hyperlipidemia were prevalent. We studied the association between BMI and various lipid/lipoprotein measures, as well as between BMI and predicted coronary heart disease probability in lean, low risk populations in Southern China. The study included 170 Buddhist monks (vegetarians) and 126 omnivore men. Interaction between BMI and vegetarian status was tested in the multivariable regression analysis adjusting for age, education, smoking, alcohol drinking, and physical activity. Compared with omnivores, vegetarians had significantly lower mean BMI, blood pressures, total cholesterol, low density lipoprotein cholesterol, high density lipoprotein cholesterol, total cholesterol to high density lipoprotein ratio, triglycerides, apolipoprotein B and A-I, as well as lower predicted probability of coronary heart disease. Higher BMI was associated with unfavorable lipid/lipoprotein profile and predicted probability of coronary heart disease in both vegetarians and omnivores. However, the associations were significantly diminished in Buddhist vegetarians. Conclusions: Vegetarian diets not only lower BMI, but also attenuate the BMI-related increases of atherogenic lipid/lipoprotein and the probability of coronary heart disease

Do Rural-Urban Identities Affect Individuals’ Health? Evidence From China

We study the relationship between household registration status (Hukou) and the state of individuals’ health to find out whether inequality in health between urban and rural population exists in China. We have used the probit model to regress the state of health on household registration using the individual-level data of the 2018 CFPS survey. We find that inequality in health between urban and rural population does exist in China. Individuals with rural Hukou have a higher probability by 1.4% to be admitted to hospital than individuals with urban Hukou. While, individuals with rural Hukou tend to over-estimate the state of their health as the probability for them to assess themselves healthy is higher by 1.7% than individuals with urban Hukou. The findings suggest that policy makers should recognize the issue of rural-urban health inequalities and take measures, such as controlling pollution in rural areas and providing high quality routine health checks for rural population to deal with the problem

Improvement of Oxygenation in Severe Acute Respiratory Distress Syndrome With High-Volume Continuous Veno-venous Hemofiltration

The efficacy and therapeutic mechanisms of continuous renal replacement therapy (CRRT) for improvement of oxygenation in acute respiratory distress syndrome (ARDS) remain controversial. These questions were addressed by retrospective analysis of severe ARDS patients admitted to the pediatric intensive care unit of our hospital from 2009 to 2015 who received high-volume continuous veno-venous hemofiltration during mechanical ventilation. There was a significant improvement in partial oxygen pressure/fraction of inspired oxygen (PaO 2 /FiO 2 ) 24 hours after CRRT onset compared with baseline (median change = 51.5; range = −19 to 450.5; P < .001) as well as decreases in FiO 2 , peak inspiratory pressure, positive end-expiratory pressure, and mean airway pressure ( P < .05). The majority of patients had a negative fluid balance after 24 hours of CRRT. White blood cell (WBC) count decreased in the subgroup with high baseline WBC count ( P < .05). PaO 2 /FiO 2 was higher in ARDS patients with extrapulmonary etiology than in those with pulmonary etiology ( P < .05). Improvement in oxygenation is likely related to both restoration of fluid balance and clearance of inflammatory mediators

Association of adverse birth outcomes with prenatal exposure to vanadium: a population-based cohort study

Background: Vanadium, an important pollutant produced from anthropogenic activities, has been suggested to be embryotoxic and fetotoxic in animal studies. However, little is known about its effects on humans. We aimed to assess the association of prenatal exposure to vanadium with the risk of adverse birth outcomes in babies born to women in China. Methods: For this population-based cohort study, the Healthy Baby Cohort, women were recruited from three cities in Hubei Province, China. Women included in this analysis were recruited from Wuhan Women and Children Medical Care Center, Wuhan. We measured urinary concentrations of vanadium and other metals simultaneously using inductively coupled plasma mass spectrometry. We used multivariable logistic regressions, with adjustment for potential confounders, to estimate the associations of natural logarithm transformed creatinine-corrected urinary vanadium (Ln-vanadium) concentrations as continuous variables and categorised into quartiles (Q; Q1: ≤0·84 μg/g creatinine, Q2: 0·84–1·40 μg/g creatinine, Q3: 1·40–2·96 μg/g creatinine, Q4: >2·96 μg/g creatinine, with the lowest quartile set as reference) with preterm delivery, early-term delivery, low birthweight, and being small for gestational age. We applied restricted cubic spline models to evaluate the dose-response relationships. Findings: Data from 7297 women recruited between Sept 22, 2012, and Oct 22, 2014, were included in this study. Urinary Ln-vanadium concentrations showed non-linear dose-response relationships with risk of preterm delivery (S-shaped, p<0·0001) and low birthweight (J-shaped, p=0·0001); the adjusted odds ratios (ORs) for increasing quartiles of urinary vanadium were 1·76 (95% CI 1·05–2·95) for Q2, 3·17 (1·96–5·14) for Q3, and 8·86 (5·66–13·86) for Q4 for preterm delivery, and 2·29 (95% CI 1·08–4·84) for Q2, 3·22 (1·58–6·58) for Q3, and 3·56 (1·79–7·10) for Q4 for low birthweight. Ln-vanadium concentrations were linearly associated with the risk of early-term delivery (linear, p<0·0001) and being small for gestational age (linear, p=0·0027), with adjusted ORs of 1·15 (95% CI 1·10–1·21) for early-term delivery and 1·12 (1·04–1·21) for being small for gestational age per unit increase in Ln-vanadium concentrations. Interpretation: Our findings reveal a relationship between prenatal exposure to higher levels of vanadium and increased risk of adverse birth outcomes, suggesting that vanadium might be a potential toxic metal for human beings. Further studies are needed to replicate the observed associations and investigate the interaction effects of prenatal exposure to different metals on adverse birth outcomes.

Midterm outcomes of open repair versus endovascular descending thoracic aortic aneurysm repairCentral MessagePerspective

Objective: The study objective was to evaluate the midterm outcome of thoracic endovascular aortic repair compared with open repair in patients with descending thoracic aortic aneurysm. Methods: From August 1993 to February 2023, 499 patients with descending thoracic aortic aneurysms underwent open repair (n = 221) or thoracic endovascular aortic repair (n = 278). Of these, 120 matched pairs were identified using propensity score matching based on age, sex, chronic lung disease, stroke, coronary artery disease, diabetes, ejection fraction, dialysis, peripheral vascular disease, prior cardiac surgery, connective tissue disease, and chronic dissection. Primary outcomes were postoperative paralysis, operative mortality, reoperation, and midterm survival. Results: After matching, the preoperative demographics and comorbidities were balanced in both groups. Intraoperatively, open repair had a lower temperature (18 °C vs 36 °C) and more patients required blood products (66% vs 8%), P < .001. Postoperatively, patients undergoing thoracic endovascular aortic repair had fewer strokes (2.5% vs 9.2%; P = .03), less dialysis (0% vs 3.3%; P = .04), and shorter length of stay (5 days vs 12 days, P < .001), but similar lower-extremity paralysis (2.5% vs 2.5%, P = 1.00) compared with open repair. Furthermore, thoracic endovascular aortic repair had higher 7-year incidence of first reoperation (16.1% vs 3.6%, P < .001) but similar operative mortality (0.8% vs 4.2%; P = .10) and 10-year survival outcome (56%; 95% CI, 43-72 vs 58%; 95% CI, 49-68; P = .55) compared with open aortic repair. The hazard ratio was 0.93 (P = .78) for thoracic endovascular aortic repair for midterm mortality and 6.87 (P < .001) for reoperation. Conclusions: Open repair could be the first option for patients with descending thoracic aortic aneurysms who were surgical candidates

Optimizing Respondent-Driven Sampling Survey to Identify Factors Associated With HIV Risk Behaviors Among Student MSM Aged 15 to 19

Male homosexual behavior dominates the mode of HIV infection among students in China. This study aims to identify factors associated with HIV risk behaviors among male students who have sex with men (student MSM) aged 15 to 19 in China. The online sampling used the standard respondent-driven sampling (RDS) method, with recruitment support from community-based organizations (CBOs) in Tianjin and Guangzhou. Multivariate logistic regression models were performed to identify factors associated with multiple HIV risk behaviors. A total of 449 subjects were recruited in this study, including 206 in Tianjin and 243 in Guangzhou. The presence of multiple HIV risk behaviors among student MSM, in many cases, was found to positively correlate with parental or friends’ awareness of their same-sex sexual behavior or sexual orientation, with some geographical differences. The prevalence of HIV risk behaviors among student MSM aged 15 to 19 was high and associated with the disclosure of their sexual orientation or their sex with males to parents and friends. These findings highlight the importance of addressing social support in HIV prevention among student MSM when delivering HIV-related education or services

An update on the prevalence, chronicity, and severity of atopic dermatitis and the associated epidemiological risk factors in the Singapore/Malaysia Chinese young adult population: A detailed description of the Singapore/Malaysia Cross-Sectional Genetics Epidemiology Study (SMCGES) cohort

Background: Atopic Dermatitis (AD) is a highly pruritic, chronic-recurrent inflammatory skin condition associated with erythematous lesions that affect a significant proportion of the population. Although AD is a non-communicable disease, it can cause pain, unbearable itchiness, sleep disturbance, loss of work productivity, and reduced quality of life. As a heterogeneous disease, AD is influenced by multiple genes and environmental triggers. As such, it is imperative to gain a deeper insight into the intricate gene-environment relationship that results in the manifestation of AD. Methods: There are 3 objectives in our study. We first aim to update the epidemiological status of AD amongst young adults in Singapore and Malaysia, in particular amongst the Chinese ethnic background. Next, we re-evaluated the possible associated risk factors, identified in our previous meta-analysis and review studies, on the current cohort. Finally, we described here a detailed disease presentation and symptoms profile of our Singapore and Malaysia Cross-Sectional Genetics Epidemiology Study (SMCGES) cohort, which forms the base population for the discovery of associated genetic factors in relation to asthma, allergic diseases and skin conditions. Based on a skin prick test (SPT) and investigator-administered medical history responses, we assessed the AD profiles of 11 494 participants and the significant modifiable and non-modifiable factors associated with disease presentation. Results: The prevalence of AD in the combined population was 13.5%. Chronic and moderate/severe AD were observed in 35.5% and 40.5% of the individuals with AD, respectively. Family history of atopic diseases, prior history of drug allergies, a history of acne, increased household family monthly income, higher number of individuals in the shared household, parental education, sedentary lifestyle, physical activities, alcoholic consumption, and even quality of diet was significantly associated with AD presentation, chronicity, and severity. Among all the factors evaluated, family and personal history of atopic diseases imposed the strongest associated risk. Conclusions: These findings supported our previous review studies and affirmed that familial history or genetic factors critically influence the development of AD in our population and environment. Environmental and other modifiable factors can also trigger AD throughout the lifetime of individuals who have especially inherited the atopic disease disposition. A better understanding of how these risk factors affect AD individuals in our population can facilitate disease surveillance, monitor disease control, and serve as a description for our future genetic epidemiology studies

LncRNA ANRIL is up-regulated in nasopharyngeal carcinoma and promotes the cancer progression via increasing proliferation, reprograming cell glucose metabolism and inducing side-population stem-like cancer cells.

Long noncoding RNAs play a vital role in diverse biological processes such as embryonic development, cell growth, and tumorigenesis. In this study, we report that LncRNA ANRIL, which encodes a 3834-nt RNA that contains 19 exons at the antisense orientation of the INK4B-ARF-INK4A gene cluster, generally up-regulated in nasopharyngeal carcinoma [1]. In a cohort of 88 NPC patients, ANRIL was highly expressed in advanced-stage cancer. Multivariate analyses revealed that ANRIL expression could serve as an independent predictor of overall survival (P = 0.027) and disease-free survival (P = 0.033). Further investigation showed that knockdown of ANRIL significantly repressed NPC cell proliferation and transformation. We also found that ANRIL could induce the percentage of side population cells (SP cells) in NPC. To meet the urgent needs of energy provision, ANRIL can also reprogram glucose metabolism via increasing glucose uptake for glycolysis, which was regulated by the mTOR signal pathway to affect the expression of essential genes in glycolysis. We concluded that ANRIL could promote NPC progression via increasing cell proliferation, reprograming cell glucose metabolism and inducing side-population stem-like cancer cells. Our results also suggested that ANRIL may serve as a novel diagnostic or prognostic biomarker and a candidate target for new therapies in NPC

Changing cancer survival in China during 2003–15: a pooled analysis of 17 population-based cancer registries

Summary: Background: From 2003 to 2005, standardised 5-year cancer survival in China was much lower than in developed countries and varied substantially by geographical area. Monitoring population-level cancer survival is crucial to the understanding of the overall effectiveness of cancer care. We therefore aimed to investigate survival statistics for people with cancer in China between 2003 and 2015. Methods: We used population-based data from 17 cancer registries in China. Data for the study population was submitted by the end of July 31, 2016, with follow-up data on vital status obtained on Dec 31, 2015. We used anonymised, individual cancer registration records of patients (aged 0–99 years) diagnosed with primary, invasive cancers from 2003 to 2013. Patients eligible for inclusion had data for demographic characteristics, date of diagnosis, anatomical site, morphology, behaviour code, vital status, and last date of contact. We analysed 5-year relative survival by sex, age, and geographical area, for all cancers combined and 26 different cancer types, between 2003 and 2015. We stratified survival estimates by calendar period (2003–05, 2006–08, 2009–11, and 2012–15). Findings: There were 678 842 records of patients with invasive cancer who were diagnosed between 2003 and 2013. Of these records, 659 732 (97·2%) were eligible for inclusion in the final analyses. From 2003–05 to 2012–15, age-standardised 5-year relative survival increased substantially for all cancers combined, for both male and female patients, from 30·9% (95% CI 30·6–31·2) to 40·5% (40·3–40·7). Age-standardised 5-year relative survival also increased for most cancer types, including cancers of the uterus (average change per calendar period 5·5% [95% CI 2·5–8·5]), thyroid (5·4% [3·2–7·6]), cervix (4·5% [2·9–6·2]), and bone (3·2% [2·1–4·4]). In 2012–15, age-standardised 5-year survival for all patients with cancer was higher in urban areas (46·7%, 95% CI 46·5–47·0) than in rural areas (33·6%, 33·3–33·9), except for patients with oesophageal or cervical cancer; but improvements in survival were greater for patients residing in rural areas than in urban areas. Relative survival decreased with increasing age. The increasing trends in survival were consistent with the upward trends of medical expenditure of the country during the period studied. Interpretation: There was a marked overall increase in cancer survival from 2003 to 2015 in the population covered by these cancer registries in China, possibly reflecting advances in the quality of cancer care in these areas. The survival gap between urban and rural areas narrowed over time, although geographical differences in cancer survival remained. Insight into these trends will help prioritise areas that need increased cancer care.
