Predicting performance of pharmacy calculations assessments via an algebra-based pre-test and other variables using a logistical regression model: A pilot study

Objective To determine the relationship between neck circumference (NC) and cardiovascular risk factors among Uygur, Kazak, Mongolian and Han populations in Boertala Mongol Autonomous Prefecture of Xinjiang. Methods A total of 4299 adults (Uygur 1237, Kazak 1047, Mongolian 812, and Han 1203) aged 20 to 79 years old were selected from a cross-sectional study of metabolic syndrome in Boertala Mongol Autonomous Prefecture of Xinjiang.Pearson's correlation was used to assess the relationship between NC and body mass index (BMI), waist circumference (WC), waist-to-hip ration (WHR), systolic blood pressur (SBP), diastolic blood pressure (DBP), fasting blood glucose (FBG), total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C) and triglyceride (TG). Linear regression and Logistic regression were used to evaluate the effects of NC on SBP, DBP, FBG, TC, LDL-C, HDL-C, TG, hypertension, high FBG and lipid disorders among multiethnic population. Results Mean NC was (36.2±3.8) cm in Uygur, (36.3±4.1) cm in Kazak, (35.9±3.6) cm in Mongolian and (35.7±4.0) cm in Han, respectively.After adjusting age and gender, in Pearson's correlation coefficients, a significant association was found between NC and BMI (for Uygur, Kazak, Mongolian and Han, r values were 0.552, 0.499, 0.709 and 0.459, respectively; all P<0.05) or WC (for Uygur, Kazak, Mongolian and Han, r values were 0.525, 0.479, 0.695 and 0.376, respectively; all P<0.05). When BMI, WC and other factors were adjusted, linear regression indicated that FBG in Uygur (t=3.746, P<0.05) and LogTG in Mongolian (t=2.876 P<0.05) were increased with NC.In Logistic regression, increased NC was a risk factor of higher FBG in Uygur (odds ratio (OR)=1.139, 95% confidence interval (CI): 1.027-1.264) and lipid disorder in Mongolian (OR=1.156, 95% CI: 1.009-1.325). Conclusions Our data suggest that NC may be associated with multiple risk factors of cardiovascular disease in Uygur, Kazak, Mongolian and Han adults, and the relationship could be different among multiethnic populations.It should be necessary to explore the role of upper-body fat in the development of metabolic disorders.

Dementia is associated with sleep disorders. However, the relationship between dementia and sleep arousal remains unclear. This study explored the associations among sleep parameters, arousal responses, and risk of mild cognitive impairment (MCI). Participants with the chief complaints of memory problems and sleep disorders, from the sleep center database of Taipei Medical University Shuang-Ho Hospital, were screened, and the parameters related to the Cognitive Abilities Screening Instrument, Clinical Dementia Rating, and polysomnography were determined. All examinations were conducted within 6 months and without a particular order. The participants were divided into those without cognitive impairment (Clinical Dementia Rating = 0) and those with MCI (Clinical Dementia Rating = 0.5). Mean comparison, linear regression models, and logistic regression models were employed to investigate the associations among obtained variables. This study included 31 participants without MCI and 37 with MCI (17 with amnestic MCI, 20 with multidomain MCI). Patients with MCI had significantly higher mean values of the spontaneous arousal index and spontaneous arousal index in the non-rapid eye movement stage than those without MCI. An increased risk of MCI was significantly associated with increased spontaneous arousal index and spontaneous arousal index in the non-rapid eye movement stage with various adjustments. Significant associations between the Cognitive Abilities Screening Instrument scores and the oximetry parameters and sleep disorder indexes were observed. Repetitive respiratory events with hypoxia were associated with cognitive dysfunction. Spontaneous arousal, especially in non-rapid eye movement sleep, was related to the risk of MCI. However, additional longitudinal studies are required to confirm their causality. Tsai C-Y, Hsu W-H, Lin Y-T, etal.

The Impact of School Building Conditions on Student Absenteeism and Performance in Upstate New York

To investigate the association between diabetes symptoms and physical activity (PA) levels among middle-aged and older Chinese adults. Data for this study were obtained from 2018 Charles data. Z test, logistic regression analysis, and linear hierarchical regression analysis were performed in 5352 individuals aged ≥50 years with complete information. In terms of diabetes, 6.8% of the middle-aged and elderly people with diabetes were detected, and 93.2% of the middle-aged and elderly people without diabetes symptoms. The proportion of middle-aged and elderly people with high PA levels was 50.5%, and the proportion of middle-aged and elderly people with low PA was 49.5%. There was a significant positive correlation between low PA and diabetes (P < .05). After adjusting demographic characteristics (gender, registered permanent residence type, education level, age, widowhood) and health status characteristics (poor mood, asthma, hyperlipidemia, disability, memory disease, self-assessment of health status, hypertension, smoking, stroke, depression), there was still a statistical significance between PA level and diabetes (P < .05). The risk of diabetes of middle-aged and elderly people in China increases with age, while the risk of diabetes of middle-aged and elderly people with low level of PA is higher. The risk of diabetes is high among middle-aged and elderly people who are old, have poor self-evaluation health, suffer from hyperlipidemia, memory disease, and asthma. The middle-aged and old people should increase their PA levels to prevent and improve diabetes.

To identify mortality trends and risk factors associated with stillbirths and neonatal deaths 1982-2011. Population-based cross-sectional study based on reported pregnancy history in Iganga-Mayuge Health and Demographic Surveillance Site (HDSS) in Uganda. A pregnancy history survey was conducted among women aged 15-49 years living in the HDSS during May-July 2011 (n = 10 540). Time trends were analysed with cubic splines and linear regression. Potential risk factors were examined with multilevel logistic regression with adjusted odds ratios (AOR) and 95% confidence intervals (CI). 34 073 births from 1982 to 2011 were analysed. The annual rate of decrease was 0.9% for stillbirths and 1.8% for neonatal mortality. Stillbirths were associated with several risk factors: multiple births (AOR 2.57, CI 1.66-3.99), previous adverse outcome (AOR 6.16, CI 4.26-8.88) and grand multiparity among 35- to 49-year-olds (AOR 1.97, CI 1.32-2.89). Neonatal deaths were associated with multiple births (AOR 6.16, CI 4.80-7.92) and advanced maternal age linked with parity of 1-4 (AOR 2.34, CI 1.28-4.25) and grand multiparity (AOR 1.44, CI 1.09-1.90). Education, marital status and household wealth were not associated with the outcomes. The slow decline in mortality rates and easily identifiable risk factors calls for improving quality of care at birth and a rethinking of how to address obstetric risks, potentially a revival of the risk approach in antenatal care.

Obesity Is Associated With Family History of ESRD in Incident Dialysis Patients

Objectives: To explore the independent correlation between serum uric acid and low-grade inflammation (measured by high-sensitivity C-reactive protein, hs-CRP) in postmenopausal women.Methods: A total of 378 healthy Iranian postmenopausal women were randomly selected in a population-based study. Circulating hs-CRP levels were measured by highly specific enzyme-linked immunosorbent assay method and an enzymatic calorimetric method was used to measure serum levels of uric acid. Pearson correlation coefficient, multiple linear regression and logistic regression models were used to analyze the association between uric acid and hs-CRP levels.Results: A statistically significant correlation was seen between serum levels of uric acid and log-transformed circulating hs-CRP (r = 0.25, p < 0.001). After adjustment for age and cardiovascular risk factors (according to NCEP ATP III criteria), circulating hs-CRP levels were significantly associated with serum uric acid levels (β = 0.20, p < 0.001). After adjustment for age and cardiovascular risk factors, hs-CRP levels ≥3 mg/l were significantly associated with higher uric acid levels (odds ratio =1.52, 95% confidence interval 1.18–1.96).Conclusion: Higher serum uric acid levels were positively and independently associated with circulating hs-CRP in healthy postmenopausal women.

Association of Metabolic Syndrome With Proximal and Synchronous Colorectal Neoplasm

To describe and compare the sociodemographic and lifestyle characteristics of urban and rural residents in Atlantic Canada. Cross-sectional analyses of baseline data from the Atlantic Partnership for Tomorrow's Health cohort were conducted. Specifically, 17,054 adults (35-69 years) who provided sociodemographic characteristics, measures of obesity, and a record of chronic disease and health behaviors were included in the analyses. Multiple linear regression and logistic regression models were used to calculate the multivariable-adjusted beta coefficients (β), odds ratios (OR), and related 95% confidence intervals (CI). After adjusting for age, sex, and province, when compared to urban participants, rural residents were significantly more likely to: be classified as very active (OR: 1.19, CI: 1.11-1.27), be obese (OR: 1.13, 1.05-1.21), to present with abdominal obesity (OR: 1.08, CI: 1.01-1.15), and have a higher body fat percentage (β: 0.40, CI: 0.12-0.68) and fat mass index (β: 0.32, CI: 0.19-0.46). Rural residents were significantly less likely to be regular or habitual drinkers (OR: 0.83, CI: 0.78-0.89). Significant differences remained after further adjustment for confounding sociodemographic, lifestyle, and health characteristics. No significant differences in smoking behavior, fruit and vegetable intake, multimorbidity, or waist circumference were found. As expected, obesity prevalence was higher in rural Atlantic Canadians. In contrast to much of the existing literature, we found that rural participants were more likely to report higher levels of total physical activity and lower alcohol consumption. Findings suggest that novel obesity prevention strategies may be needed for rural populations.

Associations between semen phytoestrogens concentrations and semen quality in Chinese men

Maternal chronic kidney disease and chronic hypertension have been linked with adverse pregnancy outcomes. We aimed to examine the association between these conditions and adverse pregnancy outcomes over the last 3 decades. We conducted this national cohort study to assess the association between maternal chronic disease (CH, CKD or both conditions) and adverse pregnancy outcomes with an emphasis on the effect of parity, maternal age, and BMI on these associations over the last three decades. We further investigated whether different subtypes of CKD had differing effects. We used data from the Swedish Medical Birth Register, including 2,788,490 singleton births between 1982 and 2012. Women with chronic kidney disease and chronic hypertension were identified from the Medical Birth Register and National Patient Register. Logistic regression models were performed to assess the associations between maternal chronic disease (chronic hypertension, chronic kidney disease, or both conditions) and pregnancy outcomes, including preeclampsia, in-labor and prelabor cesarean delivery, preterm birth, small for gestational age, and stillbirth. During the 30-year study period, 22,397 babies (0.8%) were born to women with chronic kidney disease, 13,279 (0.48%) to women with chronic hypertension and 1079 (0.04%) to women with both conditions. Associations with chronic hypertension were strongest for preeclampsia (adjusted odds ratio, 4.57; 95% confidence interval, 4.33-4.84) and stillbirth (adjusted odds ratio, 1.65; 95% confidence interval, 1.35-2.03) and weakest for spontaneous preterm birth (adjusted odds ratio, 1.07; 95% confidence interval, 0.96-1.20). The effect of chronic kidney disease varied from (adjusted odds ratio, 2.05; 95% confidence interval, 1.92-2.19) for indicated preterm birth to no effect for stillbirth (adjusted odds ratio, 1.16; 95% confidence interval, 0.95-1.43). Women with both conditions had the strongest associations for in-labor cesarean delivery (adjusted odds ratio, 1.86; 95% confidence interval, 1.49-2.32), prelabor cesarean delivery (adjusted odds ratio, 2.68; 95% confidence interval, 2.18-3.28), indicated preterm birth (adjusted odds ratio, 9.09; 95% confidence interval, 7.61-10.7), and small for gestational age (adjusted odds ratio, 4.52; 95% confidence interval, 3.68-5.57). The results remained constant over the last 3 decades. Stratified analyses of the associations by parity, maternal age, and body mass index showed that adverse outcomes remained independently higher in women with these conditions, with worse outcomes in multiparous women. All chronic kidney disease subtypes were associated with higher odds of preeclampsia, in-labor cesarean delivery, and medically indicated preterm birth. Different subtypes of chronic kidney disease had differing risks; strongest associations of preeclampsia (adjusted odds ratio, 3.98; 95% confidence interval, 2.98-5.31) and stillbirth (adjusted odds ratio, 2.73; 95% confidence interval, 1.13-6.59) were observed in women with congenital kidney disease, whereas women with diabetic nephropathy had the most pronounced increase odds of in-labor cesarean delivery (adjusted odds ratio, 3.54; 95% confidence interval, 2.06-6.09), prelabor cesarean delivery (adjusted odds ratio, 7.50; 95% confidence interval, 4.74-11.9), and small for gestational age (adjusted odds ratio, 4.50; 95% confidence interval, 2.92-6.94). In addition, women with renovascular disease had the highest increased risk of preterm birth in both spontaneous preterm birth (adjusted odds ratio, 3.01; 95% confidence interval, 1.57-5.76) and indicated preterm birth (adjusted odds ratio, 8.09; 95% confidence interval, 5.73-11.4). Women with chronic hypertension, chronic kidney disease, or both conditions are at an increased risk of adverse pregnancy outcomes which were independent of maternal age, body mass index, and parity. Multidisciplinary management should be provided with intensive clinical follow-up to support these women during pregnancy, particularly multiparous women. Further research is needed to evaluate the effect of disease severity on adverse pregnancy outcomes.

To illustrate the use of regression and logistic regression models to investigate changes over time in size of babies particularly in relation to social deprivation, age of the mother and smoking. Mean birthweight has been found to be increasing in many countries in recent years, but there are still a group of babies who are born with low birthweights. Population-based retrospective cohort study. Multiple linear regression and logistic regression models are used to analyse data on term 'singleton births' from Scottish hospitals between 1994-2003. Mothers who smoke are shown to give birth to lighter babies on average, a difference of approximately 0.57 Standard deviations lower (95% confidence interval. 0.55-0.58) when adjusted for sex and parity. These mothers are also more likely to have babies that are low birthweight (odds ratio 3.46, 95% confidence interval 3.30-3.63) compared with non-smokers. Low birthweight is 30% more likely where the mother lives in the most deprived areas compared with the least deprived, (odds ratio 1.30, 95% confidence interval 1.21-1.40). Smoking during pregnancy is shown to have a detrimental effect on the size of infants at birth. This effect explains some, though not all, of the observed socioeconomic birthweight. It also explains much of the observed birthweight differences by the age of the mother. Identifying mothers at greater risk of having a low birthweight baby as important implications for the care and advice this group receives.
