Sex differences in the association between the muscle quality index and the incidence of depression: A cross-sectional study

BACKGROUND Depression presents significant challenges to mental health care.Although phy-sical activity is highly beneficial to mental and physical health,relatively few stu-dies have conducted on the relationship between them.AIM To investigate the association between muscle quality index(MQI)and incidence of depression.METHODS The data used in this cross-sectional study were obtained from the 2011-2014 National Health and Nutritional Examination Survey,which included informa-tion on MQI,depression,and confounding factors.Multivariable logistic regre-ssion models were employed,while taking into account the complex multi-stage sampling design.A restricted cubic spline model was utilized to investigate the non-linear relationship between the MQI and depression.Additionally,subgroup analyses were performed to identify influential factors.RESULTS The prevalence of depression in this population was 8.44%.With the adjusted model,the MQI was associated with depression in females(odds ratio=0.68,95%confidence interval:0.49-0.95)but not in males(odds ratio=1.08,95%confidence interval:0.77-1.52).Restricted cubic spline adjustment of all covariates showed a significant negative non-linear relationship between depression and the MQI in females.The observed trend indicated an 80%decrease in the risk of depression for each unit increase in MQI,until a value of 2.2.Subsequently,when the MQI exceeded 2.2,the prevalence of depression increased by 20%for every unit increase in the MQI.Subgroup analyses further confirmed that the MQI was negatively associated with de-pression.CONCLUSION The MQI was inversely correlated with depression in females but not males,suggesting that females with a higher MQI might decrease the risk of depression.

The Role of the Examination Management for Medical Students in Humanities Education and Training Professional Quality

It has been proved by years of research that if the function of examination management cannot be fully understood or be used effectively, the humanities education and train of professional quality for medical students will not make a fundamental achievement. Because it is not only an academic training but also the examination management and the humanities cultivation have a close connection. The humanities cultivation which is based on the core of virtue requires a good campus environment. Therefore, we should adjust to the medical students＇ humanities quality training requirements, making the targeted reform and innovation of examination management.

Tests to measure the quality of spermatozoa at spermiation

This commentary is to critique the revised World Health Organization （WHO） semen analysis manual as it pertains to characteristics of a spermatozoon at spermiation. The aims of the revised WHO manual include improving the ＇quality of semen analysis＇ without any restriction to clinical use. Furthermore, the manual states that semen analysis may be useful for （a） ＇investigating male fertility status＇ and （b） ＇monitoring spermatogenesis during and following male fertility regula- tion.＇ However, if the analysis of ejaculated spermatozoa is intended for the purposes described in （b）, then cells that are abnormal at spermiation must be identified. This paper takes the position that the manual does not identify methods to estimate the quality of spermatozoa at spermiation. Instead, it uses a ＇gold standard＇ of sperm passing through the cervical mucus or arriving near the site of fertilization. Although this standard is appropriate for drawing conclusions regarding the probability that an individual could impregnate his partner, it is not appropriate for studying illness of the testes per se. Herein, the measures of sperm quality presented in the WHO manual are critiqued with respect to the detection of spermatozoa that were abnormal at spermiation vs. those that became abnormal subsequently. Quality assessments based on the percentage of motile or ＇viable＇ spermatozoa are meaningless. Alternative quality attributes defining spermatozoa at spermiation are presented in this paper. In conclusion, assessment of spermatozoal quality at spermiation, on the basis of quality attributes of individual ejaculated spermatozoa, is best achieved through application of （a） a new paradigm for the morphological evaluation of sperm quality and （b） modern analytical techniques to evaluate, in an adequate sample, several appropriate independent attributes in each spermatozoon in order to more accurately identify the proportion of abnormal spermatozoa.

Health-related quality of life in Parkinson's disease patients in northeastern Sicily, Italy An ecological perspective

Parkinson＇s disease has a negative impact on health-related quality of life in Parkinson＇s disease patients. Depression, cognitive impairment, coping strategies, dyskinesia, gait disorders and complications of dopaminergic drugs are the variables that most affect health-related quality of life. The ecological model of human development focuses attention on both individual and social environmental factors as targets for health interventions. From this perspective, the aim of this cross-sectional survey was to evaluate the influence of gender, family size and perceived autonomy on health-related quality of life in Parkinson＇s disease patients in nOrtheastern Sicily, Italy. Ninety Parkinson＇s disease patients, attending the Movement Disorders Clinic at IRCCS Centro Neurolesi ＂Bonino-Pulejo＂ （Messina）, were consecutively enrolled. The Unified Parkinson Disease Rating Scale motor subscale （UPDRS-Ⅲ） scores, the Parkinson Disease Questionnaire-39 Item scores （as a disease-specific measure of health-related quality of life）, scores on the Short Form （36） Health Survey Questionnaire （as a generic measure）, and answers to a brief checklist were recorded. A total of 85 Parkinson＇s disease patients （49% males and 51% females; mean age 70.8 ± 8.6 years mean UPDRS-Ⅲ 24.15 ± 6.55; mean disease duration 5.52 ± 4.65 years） completed the booklet of questionnaires. In the multivariate regression analysis, we included clinical and social variables as independent predictors of health-related quality of life. Our results suggest a potential compounding effect of ecological intrapersonal and interpersonal levels on health-related quality of life outcomes. Gender, self-evaluated autonomy and family size significantly impacted health-related quality of life. If quality of life is used as an indicator of treatment outcomes, an ecological perspective of the case history will be important to disclose relevant prognostic information and trigger personalized health care interventions.

Magnetic resonance morphometry of the loss of gray matter volume in Parkinson's disease patients

Voxel-based morphometry can be used to quantitatively compare structural differences and func-tional changes of gray matter in subjects. In the present study, we compared gray matter images of 32 patients with Parkinson’s disease and 25 healthy controls using voxel-based morphometry based on 3.0 T high-field magnetic resonance T1-weighted imaging and clinical neurological scale scores. Results showed that the scores in Mini-Mental State Examination and Montreal Cognitive Assessment were lower in patients compared with controls. In particular, the scores of visuospatial/executive function items in Montreal Cognitive Assessment were significantly reduced, but mean scores of non-motor symptoms significantly increased, in patients with Parkinson’s dis-ease. In addition, gray matter volume was significantly diminished in Parkinson’s disease patients compared with normal controls, including bilateral temporal lobe, bilateral occipital lobe, bilateral parietal lobe, bilateral frontal lobe, bilateral insular lobe, bilateral parahippocampal gyrus, bilateral amygdale, right uncus, and right posterior lobe of the cerebel um. These findings indicate that voxel-based morphometry can accurately and quantitatively assess the loss of gray matter volume in patients with Parkinson＇s disease, and provide essential neuroimaging evidence for multisystem pathological mechanisms involved in Parkinson’s disease.

Association of Health-related Quality of Life with Health Examination and Lifestyles of Government Managers in China

In order to study the association of each item of a health examination and lifestyles with health-related quality of life (HRQoL), a cross-sectional survey by a self-administered questionnaire using the 12-Item Short Form Health Survey (SF-12, version 1) was conducted on 145 government managers that took health examinations in Tongji Hospital, Wuhan, China during 2005. The results showed that the determinations of organic functions including BMI, hemoglobin, blood platelet count, urine protein, urine WBC and lipid metabolism (LDL) were associated with HRQoL. The lifestyle items including age, sex, life satisfaction, drinking alcohol and kind of alcohol drunk, drinking tea, sleep quality and adhering to bedtime, working overtime, work stress were associated with HRQoL in the multiple regression models. Sex, age and life satisfaction were the lifestyle items most closely associated with HRQoL, while LDL, hemoglobin and urine protein were the health examination items most closely associated HRQoL. This study revealed that both lifestyle and health examination items were associated with HRQoL.

Preparation of Water Based Polymeric Binders for Paper Surface Coating

Binder is an important ingredient in pigment coating as it is used to impart adhesion, gloss and flexibility to the dried film as well as binding the pigment particles together. The aim of this work was to synthesize polymeric binders via radical copolymerization of acrylic acid (AA) with maleic anhydride (MA) and with 2-acrylamido-2-methyl-1-propane sulfonic acid (AMPS). The chemical structures of the prepared binders were characterized by FTIR and 1HNMR analysis. The rheology of the prepared binders was also investigated. The prepared binders were applied in paper coating suspensions and their effects on optical, mechanical, and physical properties in addition to printability of the coated paper were studied. The results showed that acrylic maleic anhydride copolymers increased the adhesion, gave good film forming properties and good surface activity which increased print quality of paper coating. It was also found that MA/AA (50:50) and the blend between MA/AA (50:50) with AMPS:AA (30:70) have more suitable coating film properties and have highest pick resistance which is resemble to the commercial binder.

Method of effective evaluation for examination of chloride ion in concrete

The chloride ion contained in reinforced concrete seriously corrodes the steel surface and damages concrete, resulting in inferior reinforced concrete that strength seriously compromises the entire structure’s safety. Consequently, the examination of chloride ions contained in reinforced concrete becomes an important part of a complete quality control procedure. To effectively check the concentration of chloride ions in concrete, the evaluation process should be accurate and precise. Laboratory data ob- tained using existing evaluation methods for the examination of chloride ion are not sufficiently objective to yield reliable results with accuracy and consistency for each sample. An evaluation algorithm with capability to define indices of precision degree (Ep) and accuracy degree (Ea) is presented in this paper. The authors established a statistically reliable index of unbiased estimators and equations to critically examine the laboratory methods’ precision, accuracy degrees and application value for measuring chlorine ion concentration in reinforced concrete.
