Working hours and nonalcoholic fatty liver disease according to sleep duration

ABSTRACT

There is no study on the relationship between working hours and nonalcoholic fatty liver disease (NAFLD). The objective of the present study was to determine the relationship between working hours and NAFLD by sleep duration using a large set of abdominal ultrasonography examination data. Data from 194,625 patients who underwent health examinations from 2015 to 2017 were analyzed. Chi-square tests, linear-by-linear association and ANOVA were performed to compare general characteristics according to working hours. Multivariate logistic regression analysis was performed to determine the relationship between working hours and NAFLD by sleep duration. There was no significant relationship between working hours and NAFLD prevalence in the group of short sleep duration of ≤5 hours or the group of long sleep duration of ≥7 hours. The risk of NAFLD in the >52 working hour group was significantly higher (aOR, 1.09; 95% CI, 1.04–1.14) than that in the 40- to 52-hour working hour group after adjusting for confounding factors in the 5- to 6-hour sleep duration group. There was no significant difference between ≤40 working hours and 40 ~ 52 working hours in the 5 ~ 6 hours sleep duration group (aOR, 1.02; 95% CI, 0.97–1.06). In general, working hours were significantly related to NAFLD. There was a difference in the relationship between working hours and NAFLD according to sleep duration.     

Abdominal Adiposity in Six Populations of West African Descent: Prevalence and Population Attributable Fraction of Hypertension

OKOSUN, IKE S., TERRENCE E. FORRESTER, CHARLES N. ROTIMI, BABATUNDE O. OSOTIMEHIN, WALINJOM F. MUNA, AND RICHARD S. COOPER. Abdominal adiposity in six populations of West African descent: prevalence and population attributable fraction of hypertension. Obes Res. Objectives: The objective of this investigation was to examine the prevalence of abdominal adiposity and its association with the prevalence of hypertension among African descent populations in Nigeria, Cameroon, Jamaica, St. Lucia, Barbados, and the United States (US). Research Method: The data for this investigation were obtained from the International Collaborative Study on Hypertension in Blacks. Hypertension was defined as mean diastolic blood pressure ≥90 mmHg, systolic blood pressure ≥140 mmHg or current treatment with prescribed anti-hypertension medication. Abdominal overweight was defined as waist circumference (WC) ≥94 and ≥80 cm for men and women, respectively. Abdominal obesity was defined as WC ≥102 and ≥88 cm for men and women, respectively. We estimated the site-specific prevalence of abdominal overweight and obesity across age and body mass index cut-points. We also calculated the population attributable fraction (AF) of hypertension due to abdominal adiposity. Results: The prevalence of hypertension in these populations was tightly linked to abdominal adiposity. Increases in abdominal overweight accompanied an increasing degree of Westernization, rising from 6. 4% and 26. 3% in Nigeria, 16. 5% and 62. 8% in Cameroon, 15. 8% and 58. 6% in Jamaica, 14. 3% and 62. 1% in St. Lucia, 21. 4% and 70. 3% in Barbados to 38. 9%, and 76. 4% in the US for men and women, respectively. The corresponding values for abdominal obesity were 1. 6% and 12. 3% in Nigeria, 5. 1% and 38. 9% in Cameroon, 5. 5% and 34. 0% in Jamaica, 2. 7% and 40. 7% in St. Lucia, 7. 8% and 44. 7% in Barbados to 21. 7% and 54. 1% in the US for men and women, respectively. Body mass index-adjusted estimates of AF suggest that in most of these populations, especially in females, avoidance of abdominal overweight or obesity would help to curb the development of hypertension. Discussion: An important public health challenge is to clarify how lifestyle factors influence risks of abdominal adiposity and ultimately the increased risk of cardiovascular diseases.     

A case of pulmonary paragonimiasis with involvement of the abdominal muscle in a 9-year-old girl

In Korea, many people enjoy eating raw or underkooked freshwater crayfish and crabs which unfortunately may cause paragonimiasis. Here, we describe a case of pulmonary and abdominal paragonimiasis in a 9-year-old girl, who presented with a 1-month history of abdominal pain, especially in the right flank and the right inguinal area, with anorexia. A chest radiograph revealed pleural effusion in both lungs, and her abdominal sonography indicated an inflammatory lesion in the right psoas muscle. Peripheral blood analysis of the patient showed hypereosinophilia (66.0%) and an elevated total serum IgE level (>2,500 IU/ml). The pleural effusion tested by ELISA were also positive for antibodies against paragonimiasis. Her dietary history stated that she had ingested raw freshwater crab, 4 months previously. The diagnosis was pulmonary paragonimiasis accompanied by abdominal muscle involvement. She was improved after 5 cycles of praziquantel treatment and 2 times of pleural effusion drainage. In conclusion, herein, we report a case of pulmonary and abdominal paragonimiasis in a girl who presented with abdominal pain and tenderness in the inguinal area.     

A revision of the Cossulinae of Costa Rica and cladistic analysis of the world species (Lepidoptera: Cossidae)

The Cossidae are an economically important family of moths consisting of six subfamilies and more than 700 species globally. Their larvae are often of serious concern to forestry and horticulture in that they are known to bore in the branches and trunks of a wide range of trees and shrubs. Cossulinae is one of the six subfamilies of Cossidae and is restricted to the New World. As a result of this revision, the Costa Rican Cossulinae has been found to consist of five genera and 18 species. The phylogenetic relationships of all Cossulinae genera were analysed using the computer programs WinClada and NONA. Glandular organs new to Cossidae and the Lepidoptera have also been discovered. Four genera, Biocellata gen. nov. , Magulacra gen. nov. , Simplicivalva gen. nov. and Spinulata gen. nov. , and the following nine species are described as new: Biocellata bifida sp. nov. , Biocellata davisorum sp. nov. , Cossula buspina sp. nov. , Cossula duplexata sp. nov. , Cossula longirostrum sp. nov. , Cossula minutiloba sp. nov. , Simplicivalva ampliophilobia sp. nov. , Spinulata oblongata sp. nov. and Spinulata quasivinnea sp. nov. © 2008 The Linnean Society of London, Zoological Journal of the Linnean Society, 2008, 154 , 222–277.     

腹主动脉瘤炎症机制的研究进展

腹主动脉瘤是血管外科最高危的血管退化性疾病之一,其最严重的后果是由于薄弱的动脉管壁无法承受血流冲击,导致动脉瘤壁破裂,引起的猝死。随着我国人口老龄化形势日趋严峻,腹主动脉瘤的发病率也逐年上升,成为威胁我国人民生命健康的重要疾病之一。随着对腹主动脉瘤认识的进步,影像学检查手段的增多,该疾病的确诊率已大大提高,但其具体的发病机制仍不完全清楚。目前已知腹主动脉瘤的发生与吸烟、性别、氧化应激、基质蛋白酶、血脂等多种因素相关,最新的研究显示炎症反应在腹主动脉瘤的发生发展过程中起到重要作用,本文主要对腹主动脉瘤与白细胞相关的炎症反应机制的最新研究进展予以综述。     

Trends of Abdominal Adiposity in White,Black, and Mexican‐American Adults, 1988 to 2000

Objective: To describe changes in the distribution of waist circumference (WC) and abdominal obesity (AO) in white, black, and Mexican‐American adults from 1988 through 2000. Research Methods and Procedures: Nationally representative cross‐sectional surveys of adults 20 to 79 years of age were examined using data from U.S. National Health and Nutrition Examination Surveys of 1988 to 1994 and 1999 to 2000. AO was defined as WC ≥102 cm in men and ≥88 cm in women. Results: There was a gradient of increasing WC and AO with increasing age in both study periods in whites and blacks. In men, the average increase between the study periods in overall WC in whites, blacks, and Mexican Americans were 3, 3.3, and 3.4 cm, respectively. The corresponding values in women were 2.4, 5.3, and 3.7 cm, respectively. In men, the percentage change in prevalence of AO between 1988 and 2000 ranged from 5.5% in Mexican‐American men to 8.2% in white men. In women, there was a 1.7% decrease in AO in Mexican Americans, whereas there was an increase of 6.3% for whites and 7% for blacks. Discussion: Despite increased understanding of the need for screening and treatment for obesity, this study indicates increasing prevalence of AO in white and black Americans. Without concerted effort to reduce the prevalence of overall obesity, the increasing prevalence of AO is likely to lead to increased prevalence of metabolic syndromes in the United States. Our results highlight the need to design evidence‐based programs that show promise for long‐term health behavior changes to facilitate the prevention of AO and related comorbidities.     

Transcervical collection of equine conceptuses between 10 and 16 days after ovulation

To recover intact Day-10.5 to Day-16.5 equine conceptuses (Day 0 = ovulation), a rigid catheter was used for 131 collections from donor mares diagnosed pregnant by ultrasonography. A total of 139 conceptuses were recovered, comprising 124 singletons, six pairs of twins and one set of triplets. Of these, 120 (86%) were intact after the collection, 14 (10%) had collapsed, and in five cases (4%), collapsed trophoblastic membranes were surrounded by an intact capsule. The recovery rate of intact conceptuses ranged from 99% on Days 10.5 to 12.5 to 40% on Day 16.5. More uterine flushes per recovery were needed to collect conceptuses on Day 14.5 than on Days 10.5 and 11.5 (x +/- SEM : 3.1 +/- 0.5 vs 1.4 +/- 0.1 and 1.3 +/- 0.2 flushes, respectively, P<0.05), and the total volume of flushing medium used was greater on Day 14.5 than on Days 10.5, 11.5 and 12.5 (1040 +/- 193 vs 406 +/- 49, 396 +/- 48 and 499 +/- 59 ml, respectively, P<0.01). Seventy of the 100 mares inseminated at the first estrus following embryo collection became pregnant, indicating that the technique used had no major effect on subsequent fertility.     

鸡PPAR基因单核苷酸多态与脂肪性状相关的研究

以AA肉鸡和 3个中国地方鸡品种 (石岐杂、北京油鸡、白耳鸡 )为实验材料 ,用 7对引物对PPAR α基因整个编码区用PCR SSCP方法进行了扫描 ,结果发现引物 4扩增片段上有一个C T的单碱基突变 ,使鸡群中表现出 3种基因型 (AA、AB、BB)。统计结果发现 3种基因型在各品种中的分布不一致 ,AA肉鸡同中国地方鸡品种差异很大 ,χ2 独立性检验差异极显著 (P <0 0 1)。将AA肉鸡 3种基因型同腹脂等屠体性状进行方差分析 ,结果表明BB基因型与其他 2种基因型相比有较高的腹脂重和腹脂率 ,同AA型比较差异显著 (P <0 0 5 )。因此推测PPAR α基因可能是影响鸡脂肪代谢的主效基因或与控制该性状的主效基因连锁 ,并且能够用于对鸡脂肪性状进行分子标记辅助选择。     

Abdominal fat and risk of coronary heart disease in patients with peripheral arterial disease

Objective: We investigated whether the presence of concomitant coronary heart disease (CHD) in patients with peripheral arterial disease (PAD) can be explained by intra‐abdominal fat accumulation and compared different measures of adiposity as predictors of CHD in patients with PAD. Research Methods and Procedures: Data were collected from patients enrolled in the Second Manifestations of ARTerial disease (SMART) study, an ongoing prospective cohort study of patients with manifest vascular disease or vascular risk factors at the University Medical Centre Utrecht. The current analysis includes 315 patients, mean age 59 ± 10 years, who had PAD with (n = 79) or without (n = 236) CHD. Parameters of adiposity were measured, and intra‐abdominal fat and subcutaneous fat were measured ultrasonographically. Metabolic syndrome was defined according to Adult Treatment Panel III. Results: The prevalence of metabolic syndrome was higher among patients with CHD (63%) than among patients without CHD (48%). All parameters of adiposity indicated more fat in patients with CHD, except for subcutaneous fat. Waist circumference was associated with 64% higher prevalence of CHD (confidence interval, 20% to 123%) per 1 standard deviation increase in waist circumference after adjustment for age and sex. The odds ratio for waist circumference remained virtually the same after additional adjustment for the components of the metabolic syndrome and smoking. Discussion: An increased waist circumference, a crude measure of intra‐abdominal fat, is associated with an increased risk of concomitant CHD in patients with PAD.
