Predictors of Weight Loss in Obese Older Adults: Findings from the USA and the UK

ObjectiveTo examine the prevalence and demographic predictors of clinically meaningful weight loss in community samples of obese older adults in the USA and the UK.MethodsData were from obese older adults (BMI ≥ 30 kg/m²; age ≥ 52 years), free of a cancer diagnosis, from the Health and Retirement Study (HRS; n = 3398) and the English Longitudinal Study of Ageing (ELSA; n = 998). Weight change was assessed from 2004 to 2008. Multivariable logistic regression tested whether age, sex, ethnicity, marital status, education, or BMI predicted ≥ 5% weight loss.ResultsOver a quarter (28.7%) of obese participants from HRS and 16.6% from ELSA lost ≥ 5% weight. Being female (odds ratio (OR) = 1.31, 95% confidence interval (CI) = 1.11-1.54) and heavier (BMI ≥ 35 kg/m²) (OR = 1.60, 95% CI = 1.37-1.87) predicted weight loss in HRS. Trends were similar in ELSA (female: OR = 1.18, 95% CI = 0.83-1.69; BMI ≥ 35 kg/m²: OR = 1.24, 95% CI = 0.85-1.82). ORs were increased in ≥ 65-year-olds in HRS (OR = 1.55, 95% CI = 1.33-1.81), and reduced in married people in ELSA (OR = 0.69, 95% CI = 0.48-1.00). Neither education nor ethnicity predicted weight loss in either cohort.ConclusionA high proportion of obese older adults experience clinically meaningful weight loss, but few demographic variables consistently predict weight loss in this population.Key Words: Weight loss, Aging, Obesity, Prevalence, Predictors     

Disparities in uptake of BRCA1/2 genetic testing in a randomized trial of telephone counseling

PurposeAs genetic counseling and testing become more fully integrated into clinical care, alternative delivery models are increasingly prominent. This study examines predictors of genetic testing for hereditary breast/ovarian cancer among high-risk women in a randomized trial of in-person versus telephone-based genetic counseling.MethodsMethods include multivariable logistic regression and interaction analyses.ResultsOf the 669 participants, 600 completed counseling and 523 received test results. As previously reported, participants randomized to telephone counseling were significantly less likely to be tested. In intention-to-treat analyses, completion of counseling and testing was associated with: race/ethnicity (odds ratio (OR) = 1.96, 95% confidence interval (CI): 1.20–3.20), perceived stress (OR = 0.89, 95% CI: 0.81–0.98), knowledge (OR = 1.12, 95% CI: 1.02–1.23), and randomization group (OR = 1.48, 95% CI: 1.01–2.16). Further, race/ethnicity moderated the association between randomization group and testing; minority women receiving telephone counseling were least likely to complete testing.ConclusionEvidence for logistical and communication-based explanations for this interaction is presented. The overall increased access made possible with telephone genetic counseling should be considered in light of the possibility that this may also lead to lower rates of testing among high-risk minority women. Additional care should be taken to assess and address potential barriers when services are delivered by telephone.Genet Med17 6, 467–475.     

Predictors of eHealth Usage: Insights on The Digital Divide From the Health Information National Trends Survey 2012

Background

Recent eHealth developments have elevated the importance of assessing the extent to which technology has empowered patients and improved health, particularly among the most vulnerable populations. With noted disparities across racial and social groups in chronic health outcomes, such as cancer, obesity, and diabetes, it is essential that researchers examine any differences in the implementation, uptake, and impact of eHealth strategies across groups that bear a disproportionate burden of disease.

Objective

The goal was to examine eHealth use by sociodemographic factors, such as race/ethnicity, socioeconomic status (SES), age, and sex.

Methods

We drew data from National Cancer Institute’s 2012 Health Information National Trends Survey (HINTS) (N=3959) which is publicly available online. We estimated multivariable logistic regression models to assess sociodemographic predictors of eHealth use among adult Internet users (N=2358) across 3 health communication domains (health care, health information–seeking, and user-generated content/sharing).

Results

Among online adults, we saw no evidence of a digital use divide by race/ethnicity. However, there were significant differences in use by SES, particularly for health care and health information–seeking items. Patients with lower levels of education had significantly lower odds of going online to look for a health care provider (high school or less: OR 0.50, 95% CI 0.33-0.76) using email or the Internet to communicate with a doctor (high school or less: OR 0.46, 95% CI 0.29-0.72), tracking their personal health information online (high school or less: OR 0.53, 95% CI 0.32-0.84), using a website to help track diet, weight, and physical activity (high school or less: OR 0.64, 95% CI 0.42-0.98; some college: OR 0.67, 95% CI 0.49-0.93), or downloading health information to a mobile device (some college: OR 0.54, 95% CI 0.33-0.89). Being female was a consistent predictor of eHealth use across health care and user-generated content/sharing domains, whereas age was primarily influential for health information–seeking.

Conclusions

This study illustrates that lower SES, older, and male online US adults were less likely to engage in a number of eHealth activities compared to their counterparts. Future studies should assess issues of health literacy and eHealth literacy and their influence on eHealth engagement across social groups. Clinical care and public health communication efforts attempting to leverage Web 2.0 and 3.0 platforms should acknowledge differential eHealth usage to better address communication inequalities and persistent disparities in health.     

Racial and insurance status disparities in imaging modality among pediatric patients diagnosed with appendicitis

BackgroundStudies have assessed the type of diagnostic imaging used in the treatment of appendicitis in children. Few studies investigated racial/ethnic and insurance disparities in imaging modalities used in pediatric patients diagnosed with appendicitis. Our study seeks to determine whether race/ethnicity and insurance status are associated with imaging modality chosen for pediatric patients diagnosed with appendicitis in the emergency department.MethodsThis was a retrospective cohort study utilizing data from the National Hospital Ambulatory Medical Care Survey (NHAMCS) from 2010 to 2019. We included children <18 years old with a ICD-9-CM and ICD-10-CM diagnosis of appendicitis. Exposures were patient race/ethnicity and insurance status. Outcome of interest was imaging modality. We conducted adjusted survey logistic regression to evaluate the patient characteristics and receipt each of the imaging modalities among those with a diagnosis of appendicitis.ResultsOf 308,140,115 emergency department (ED) visits, 1,126,865 (0.37%) had a diagnosis of appendicitis. Overall, male patients were more likely to receive CAT scan in comparison to female children (OR=2.52, 95% CI= 1.16–5.49). Additionally, Hispanic children who had significantly greater odds of obtaining ultrasound (OR= 4.56, 95% CI=1.09–19.12). Hispanic children were also less likely to receive x-ray (OR= 0.31, 95% CI=0.11–0.89) or computed tomography (CT) scans (OR= 0.23, 95% CI=0.07–0.76). Children diagnosed with appendicitis who had insurance other than private, Medicare, Medicaid, or self-pay were significantly more likely to receive x-ray studies (OR=4.39, 95% CI= 1.23–15.69).Conclusions and global health implicationsThis study demonstrated the presence of racial/ethnic and insurance status disparities in the imaging modality chosen to assist in diagnosing appendicitis in pediatric patients.     

Sociodemographic,behavioral, and clinical factors associated with low atrial fibrillation knowledge among older adults with atrial fibrillation: The SAGE-AF study

BackgroundManagement of AF requires patient engagement in disease management which requires adequate knowledge about AF.ObjectiveTo identify the patient characteristics associated with low AF knowledge among older adults with AF.MethodsThe SAGE-AF cohort enrolled adults aged ≥65 diagnosed with AF in 2016?2018. Patient characteristics associated with low AF knowledge (<6/8 JAKQ items correct) were examined using multivariable adjusted logistic regression models.ResultsParticipants (N = 950) were on average 74 years old (SD: 6.7), 50 % female, and 87 % non-Hispanic white. The average JAKQ score was 68.7 (SD: 17.1), and 78 % had low AF knowledge. Participants aged ≥ 75 (OR: 1.55, 95 % CI: 1.03, 2.33), without a college degree (OR: 0.46, 95 % CI: 0.32, 0.65), cognitively impaired (OR: 1.72, 95 % CI: 1.15, 2.58), with a history of anxiety (OR: 1.76, 95 % CI: 1.09, 2.83), myocardial infarction (OR: 1.82, 95 % CI: 1.08, 3.07), and heart failure (OR: 1.84, 95 % CI: 1.16, 2.91) were more likely to have low AF knowledge.Practice implicationsCharacteristics available in the electronic medical record may identify patients at risk for low AF knowledge. Formal assessment of AF knowledge may identify areas of weakness and allow for targeted education.     

Attendance of men at the familial cancer clinic: what they value from the consultation

PurposeThis study examined what men from high-risk breast/ovarian cancer families valued from attending a familial cancer clinic.MethodsOne hundred men from families with a BRCA1 or BRCA2 mutation completed a self-administered questionnaire.ResultsSeventy- two percent (72%) of men attended the familial cancer clinic at the request of a family member. Multivariate analyses showed that men with a preference for a collaborative decision-making style (B = −4.651, 95% CI = −9.014 to −0.289, P = 0.04), those with lower levels of education (B = −4.850, 95% CI = −9.16 to −0.537, P = 0.03), and those with higher levels of cancer-related anxiety (intrusion) (B = 0.920, 95% CI = 0.441–1.399, P < 0.001) were more likely to value emotional support from the clinic. Men with a collaborative decision-making style (B = −2.68, 95% CI = −4.91 to −0.467, P = 0.02) were less likely, and those with higher total levels of cancer-related anxiety (intrusion and avoidance) (B = 0.393, 95% CI = 0.008–0.779, P = 0.04) were more likely to value receiving information from the clinic.ConclusionsA preference for collaborative decision making and cancer-related anxiety predicted men valuing information and emotional support from the consultation. The finding that men's attendance is initiated by family members highlights the value men place on family responsibility.     

ORCA,a values-based decision aid for selecting additional findings from genomic sequencing in adults: Efficacy results from a randomized trial

PurposeIndividuals having genomic sequencing can choose to be notified about pathogenic variants in genes unrelated to the testing indication. A decision aid can facilitate weighing one’s values before making a choice about these additional results.MethodsWe conducted a randomized trial (N = 231) comparing informed values-choice congruence among adults at risk for a hereditary cancer syndrome who viewed either the Optional Results Choice Aid (ORCA) or web-based additional findings information alone. ORCA is values-focused with a low-literacy design.ResultsIndividuals in both arms had informed values-choice congruence (75% and 73% in the decision aid and web-based groups, respectively; odds ratio [OR] = 1.10, 95% CI = 0.58-2.08). Most participants had adequate knowledge (79% and 76% in the decision aid and web-based groups, respectively; OR = 1.20, 95% CI = 0.61-2.34), with no significant difference between groups. Most had information-seeking values (97% and 98% in the decision aid and web-based groups, respectively; OR = 0.59, 95% CI = 0.10-3.61) and chose to receive additional findings.ConclusionThe ORCA decision aid did not significantly improve informed values-choice congruence over web-based information in this cohort of adults deciding about genomic results. Both web-based approaches may be effective for adults to decide about receiving medically actionable additional results.     

Use of the Internet as a Health Information Resource Among French Young Adults: Results From a Nationally Representative Survey

Background

The Internet is one of the main resources of health information especially for young adults, but website content is not always trustworthy or validated. Little is known about this specific population and the importance of online health searches for use and impact. It is fundamental to assess behaviors and attitudes of young people looking for online health-related information and their level of trust in such information.

Objective

The objective is to describe the characteristics of Internet users aged 15-30 years who use the Web as a health information resource and their trust in it, and to define the context and the effect of such use on French young adults’ behavior in relation to their medical consultations.

Methods

We used the French Health Barometer 2010, a nationally representative survey of 27,653 individuals that investigates population health behaviors and concerns. Multivariate logistic regressions were performed using a subsample of 1052 young adults aged 15-30 years to estimate associations between demographics, socioeconomic, and health status and (1) the use of the Internet to search for health information, and (2) its impact on health behaviors and the physician-patient relationship.

Results

In 2010, 48.5% (474/977) of Web users aged 15-30 years used the Internet for health purposes. Those who did not use the Internet for health purposes reported being informed enough by other sources (75.0%, 377/503), stated they preferred seeing a doctor (74.1%, 373/503) or did not trust the information on the Internet (67.2%, 338/503). However, approximately 80% (371/474) of young online health seekers considered the information found online reliable. Women (P<.001) and people with higher sociocultural positions (OR 0.5, 95% CI 0.3-0.9 and OR 0.4, 95% CI 0.2-0.7 for employees and manual workers, respectively, vs individuals with executive or manager positions) were more likely to use the Internet for health purposes. For a subsample of women only, online health seeking was more likely among those having a child (OR 1.8, 95% CI 1.1-2.7) and experiencing psychological distress (OR 2.0, 95% CI 1.0-4.0). Finally, for online health seekers aged 15-30 years, one-third (33.3%, 157/474) reported they changed their health behaviors (eg, frequency of medical consultations, way of taking care of one’s own health) because of their online searches. Different factors were associated with different outcomes of change, but psychological distress, poor quality of life, and low income were the most common.

Conclusions

The Internet is a useful tool to spread health information and prevention campaigns, especially to target young adults. Young adults trust online information and consider the Internet as a valid source of health advice. Health agencies should ensure the improvement of online health information quality and the creation of health-related websites and programs dedicated to young adults.     

Association between HSD17B1 rs605059 polymorphisms and the risk of uterine diseases: a systemic review and meta-analysis

The aim of this study was to evaluate the HSD17B1 gene polymorphisms in the risks of endometrial cancer, endometriosis and uterine leiomyoma by meta-analysis. A comprehensive electronic search was conducted in PubMed, Medline (Ovid), Embase, Weipu, Wanfang and CNKI. The pooled ORs were performed using the Revman 5.2 softerware. 8 case-control studies were included: 3 were about endometrial cancer, 4 were about endometriosis and 1 was about uterine leiomyoma. The result showed no significant association between HSD17B1 rs605059 gene polymorphisms and risks of endometrial cancer (AA vs. AG+GG: OR = 1.11, 95% CI = 0.94-1.32; AA+AG vs. GG: OR = 1.79, 95% CI = 0.42-7.52; AG vs. AA+ GG: OR = 0.87, 95% CI = 0.76-1.00; AA vs. GG: OR = 1.43, 95% CI = 0.62-3.30; A vs. G: OR = 1.00, 95% CI = 0.91-1.11) or endometriosis (AA vs. AG+GG: OR = 0.99, 95% CI = 0.75-1.32; AA+AG vs. GG: OR = 1.73, 95% CI = 0.92-3.25; AG vs. AA+ GG: OR = 1.24, 95% CI = 1.00-1.53; AA vs. GG: OR = 1.54, 95% CI = 0.79-2.97; A vs. G: OR = 1.23, 95% CI = 0.90-1.68). No association was found in a subgroup analysis based on Asian ethnicity for endometriosis. This meta-analysis suggested that HSD17B1 rs605059 polymorphisms were not associated with the risks of endometrial cancer and endometriosis. Further studies are needed to validate the conclusion and clarify the relationship between HSD17B1 rs605059 polymorphisms and the risk of uterine leiomyoma.     

Association of Polymorphism rs1045411 in the HMGB1 Gene with Cancer Risk: Evidence from a Meta-analysis

The high-mobility group box protein 1 (HMGB1) rs1045411 polymorphism has been demonstrated to be associated with cancer risk in some studies. However, the results regarding this topic are inconsistent. A meta-analysis was applied to elucidate the association between the HMGB1 rs1045411 polymorphism and cancer risk. Ten relevant studies were subjected to our analysis, and pooled odds ratios (ORs) and 95% confidence intervals (CIs) were calculated. In total, of 3,918 cases and 5,296 controls were included in this study. The pooled ORs were calculated using a random-effects or fixed-effects model according to the heterogeneity. The pooled results revealed that TT genotype was significantly related to increased cancer risk in the comparisons of TT vs. CC+TC (OR=1.35; 95% CI: 1.09-1.67; p=0.005). Though no statistical significance was achieved between HMGB1 rs1045411 polymorphism and cancer risk in other four genetic models (T vs. C: OR=1.08, 95% CI 0.90-1.30; TC vs. CC: OR=1.01, 95% CI 0.82-1.24; CC vs. TC+TT: OR=0.95, 95% CI 0.77-1.18; TT vs. CC: OR=1.42; 95% CI 0.98-2.05), a trend of increased risk could be drawn. In the subgroup analysis by type of malignancy and ethnicity, no obvious difference was found in the tumour risk regarding the HMGB1 rs1045411 polymorphism amongst the cancer types except for breast cancer (OR=1.94; 95% CI: 1.05-3.59; p=0.03) and hepatocellular carcinoma (OR=1.82; 95% CI: 1.15-2.88; p=0.01), while rs1045411 polymorphism was positively associated with risks of cancer amongst Hans (OR=1.37; 95% CI: 1.11-1.69; p=0.004) rather than Caucasians (OR=0.89; 95% CI: 0.26-3.02; p=0.01). These results suggest that the HMGB1 rs1045411 polymorphism might be associated with increased cancer risk.     

Prevalence of Cigarette Smoking among Adult Cancer Survivors in Korea

PurposeCigarette smoking is associated not only with increased risk of cancer incidence, but also influences prognosis, and the quality of life of the cancer survivors. Thus, smoking cessation after cancer diagnosis is necessary. However, smoking behavior among Korean cancer-survivors is yet unknown.ResultsOverall, 2.1% of Korean adults were cancer-survivors. The smoking rate of Korean cancer-survivors was lower than that of non-cancer controls (7.8±1.3% vs. 26.4±0.4%, p<0.001). However, 53.4% of the cancer-survivors continued to smoke after their cancer diagnosis. In multivariate analysis, male gender [odds ratio (OR), 6.34; 95% confidence interval (CI), 2.62-15.31], middle-aged group (OR, 2.74; 95% CI, 1.12-6.72), the lowest income (OR, 4.10; 95% CI, 1.19-14.15), living with smoking family member(s) (OR, 5.49; 95% CI, 2.42-12.48), and the poor self-perceived health status (OR, 2.78; 95% CI, 1.01-7.71) were independently associated with persistent smoking among Korean cancer-survivors.ConclusionThe smoking rate among Korean cancer survivors is low. However, the smoking cessation rate after the cancer diagnosis is also low. This mandates comprehensive and systematic intervention for smoking cessation among cancer-survivors.     

A case-control study on risk factors of breast cancer in China

Introduction

To screen the risk factors associated with breast cancer among Chinese women in order to evaluate the individual risk of developing breast cancer among women in China.

Material and methods

A case-control study on 416 breast cancer patients and 1156 matched controls was conducted in 14 hospitals in 8 provinces of China in 2008. Controls were age- and region-matched to the cases. Clinicians conducted in-person interviews with the subjects to collect information on demographics and suspected risk factors for breast cancer that are known worldwide. Conditional logistic regression was used to derive odds ratios (OR) and 95% confidence intervals (CI) for the associations between risk factors and breast cancer.

Results

Compared with matched controls, women with breast cancer were significantly more likely to have higher body mass index (BMI, OR = 4.07, 95% CI: 2.98-5.55), history of benign breast disease (BBD) biopsy (OR = 1.68, 95% CI: 1.19-2.38), older age of menarche (AOM) (OR = 1.41, 95% CI: 1.07-1.87), stress anticipation (SA), for grade 1-4, OR = 2.15, 95% CI: 1.26-3.66; for grade 5-9, OR = 3.48, 95% CI: 2.03-5.95) and menopause (OR = 2.22, 95% CI: 1.50-3.282) at the level of p < 0.05. Family history of breast cancer (FHBC) in first-degree relatives (OR = 1.66, 95% CI: 0.77-3.59) and use of oral contraceptives (OC) (OR = 1.59, 95% CI: 0.83-3.05) were associated with an increased risk of breast cancer at the level of p < 0.20.

Conclusions

Our results showed that BMI, history of BBD biopsy, older AOM, SA and menopause were associated with increased risk of breast cancer among Chinese women. The findings derived from the study provided some suggestions for population-based prevention and control of breast cancer in China.     

Determinants of participation in cancer support groups: The role of health beliefs

Background: Although considerable attention has been directed toward cancer support groups, little is known about how often these services are actually used in clinical practice or the factors that influence participation. Purpose: Drawing in part on the Health Belief Model, this study examined group participation and its correlates among 425 patients with diverse malignancies treated at a large academic oncology center. Method: Patients were surveyed regarding utilization rates, health beliefs, and medical and demographic characteristics. Results: Only a small number of patients reported having participated in groups (8.0%). Consistent with the model, in univariate analyses, participation was significantly related to greater perceptions of illness severity (p < .0001), greater perceived benefits (p < .01), fewer perceived barriers (all p < .01), and greater cues for action (i.e., recommendation by family/friends, p < .000001). In multivariate analyses controlling for disease site and other covariates, the strongest predictors included recommendation by family/friends (OR = 5.04; CI = 1.98–12.81), perceived seriousness of the illness (OR = 4.07; CI = 1.42–11.60), and geographical residence (OR = 2.74; CI = 1.09–6.93). Conclusion: Results suggest that participation might be increased by involving the patient’s support network, improving access in underserved rural communities, addressing illness appraisals, and increasing outreach to certain diagnostic groups.     

Prevalence and sociodemographic correlates of diabetes among adults in Namibia and South Africa

ObjectiveThe aims of this study were to understand the prevalence and sociodemographic characteristics associated with diabetes among adults in Namibia and South Africa.MethodsData from the Demographic and Health Survey for Namibia (2013) and South Africa (2016) were analyzed. The dependent variable, diabetes, was defined using lab values for blood glucose≥ 126 for Namibia, and hemoglobin A1c (HbA1c) ≥ 6.5% for South Africa. Logistic regression was used to identify independent correlates of diabetes for each country. Demographic (age, sex, geographic location, number of children), economic (wealth index, education level), and cultural (religion – Namibia, ethnicity – South Africa) factors were added in blocks to the models.ResultsIn Namibia, 4.6% had diabetes based on blood glucose, and 14.6% had diabetes based on HbA1c in South Africa. In Namibia, after adjustment, higher wealth was independently associated with diabetes (OR:1.67; 95% CI: 1.11, 2.50). In South Africa, after adjustment, those who were older (OR: 1.06; 95% CI: 1.04, 1.07), female (OR: 1.25; 95% CI: 1.03, 1.52), lived in a rural area (OR: 1.54; 95% CI: 1.20, 1.96), and Black (OR: 2.27; 95% CI: 1.17, 4.42) or Other (OR: 5.74; 95% CI: 2.50, 13.20) compared to White, had increased odds of diabetes.ConclusionsPrevalence of diabetes is high in South Africa and relatively low in Namibia using reliable laboratory diagnostic indices. Strategies to address the rising burden of non-communicable diseases like diabetes are needed in sub-Saharan Africa.     

Association of GPs’ risk attitudes,level of empathy,and burnout status with PSA testing in primary care

BackgroundRates of prostate specific antigen (PSA) test ordering vary among GPs.AimTo examine whether GPs’ risk attitude, level of empathy, and burnout status are associated with PSA testing.MethodPSA tests from 2012 were retrieved from a register and classified as incident (that is, the first PSA test within 24 months), repeated normal, or repeated raised tests. This was merged with information on GPs’ risk attitudes, empathy, and burnout status from a 2012 survey.ResultsPatients registered with a GP with a high score on anxiety caused by uncertainty (odds ratio [OR] 1.03, 95% confidence interval [CI] = 1.00 to 1.06, P = 0.025) or concern about bad outcomes (OR 1.04; 95% CI = 1.00 to 1.08, P = 0.034) were more likely to have an incident PSA test, whereas those registered with a GP with increased tolerance for ambiguity were less likely (OR 0.98, 95% CI = 0.96 to 1.00, P = 0.025). Patients registered with a GP reporting high tolerance for ambiguity (OR 0.96, 95% CI = 0.94 to 0.99, P = 0.009) or high propensity to risk-taking (OR 0.97, 95% CI = 0.93 to 1.00, P = 0.047) were less likely to have a repeated normal PSA test.ConclusionVarious aspects of GPs’ risk-taking attitudes were associated with patients’ probability of having an incident and a repeated normal PSA test. The probability of having a repeated raised PSA test was not influenced by any of the psychological factors. Burnout and empathy were not associated with PSA testing.     

Physical inactivity and cognitive impairment in Korean older adults: gender differences in potential covariates

Background: Physical inactivity is one major lifestyle risk factor of mild cognitive impairment with ageing.

Aim: To investigate whether or not potential covariates modulate the association between physical activity (PA) and cognitive impairment in older adults.

Subjects and methods: Data from 10?245 Korean older adults (5817 women) were used.

Results: High PA older adults were younger and longer educated and had lower comorbidity and depression than low PA older adults. Compared with low PA men, moderate PA men only had a significantly lower odds-ratio (OR) and 95% confidence interval (95% CI) (OR?=?0.795, 95% CI?=?0.654?～?0.965, p?=?0.021) for having cognitive impairment, even after adjusting for measured covariates, which was no longer significant when additionally adjusted for comorbidity (OR?=?0.862, 95% CI?=?0.707?～?1.051, p?=?0.143). Compared with low PA women, moderate and high PA women had significantly lower risks of cognitive impairment (OR?=?0.830, 95% CI?=?0.712?～?0.969, p?=?0.018 and OR?=?0.784, 95% CI?=?0.651?～?0.943, p?=?0.010, respectively), even after adjusting for the measured covariates including comorbidity, which was no longer significant when additionally adjusted for depression (OR?=?0.897, 95% CI?=?0.776?～?1.049, p?=?0.173 and OR?=?0.919, 95% CI?=?0.761?～?1.111, p?=?0.385, respectively).

Conclusion: These findings suggest that gender differences in the covariates modulate the relationship between physical activity and cognitive decline in older Korean adults.     

Role of the family in Treatment Decision-Making process for Omani women diagnosed with breast cancer

Objective

There is limited number of studies from Arabic countries on the participation of family members in Treatment decision-making (TDM) process. The aim of this study is to evaluate the role of family members in the TDM process among adult Omani women diagnosed with breast cancer.

Racial differences in symptoms, comorbidity, and treatment for major depressive disorder among black and white adults

Objective: Racial differences in the clinical nature of major depressive disorder (MDD) could contribute to treatment disparities, but national data with large samples are limited. Our objective was to examine black-white differences in clinical characteristics and treatment for MDD from one of the largest, national community samples of US adults.Methods: Non-Hispanic black and white adults (n = 32752) from the 2001–2002 National Epidemiologic Survey on Alcohol and Related Conditions produced data on 1866 respondents who met criteria for MDD based on the Diagnosfic and Statistical Manual of Mental Disorders (Fourth Edition) in the preceding 12 months. Outcome measures were depressive symptoms, comorbid psychiatric and medical disorders, disability, and treatment.Results: Blacks with MDD had significantly higher odds of initial insomnia, early-morning awakening, and restlessness than whites. Odds of hypertension (odds ratio [OR], 2.16; 95% confidence interval [CI], 1.48-3.14), obesity (OR, 1.98; 95% CI, 1.45-2.69), and liver disease (OR, 3.68; 95% CI, 1.20-11.30) were higher among blacks than whites. In unadjusted models, blacks had greater impairment than whites in social and physical functioning. However, adjusting for sociode-mographic characteristics eliminated these differences. Blacks were less likely than whites to receive outpatient services (OR, 0.51; 95% CI, 0.36-0.72) and be prescribed medications for MDD, but were more likely to receive emergency room and inpatient treatment.Conclusions: We found few racial differences in depressive symptoms, psychiatric comorbidity, and disability after adjusting for sociodemographic factors. Blacks' lower utilization of ambulatory treatment for MDD and greater medical comorbidity, emergency department use, and hospitalization suggests that management of MDD among blacks should be emphasized in primary care or other settings where treatment is more accessible.     

Association of RASSF1A hypermethylation with risk of HBV/HCV-induced hepatocellular carcinoma: A meta-analysis

BackgroundResearchers have discovered a large number of DNA methylation patterns in human cancer. These cancer-specific methylation patterns can provide information for the diagnosis, treatment, and prognosis of cancer. Methylation studies can find new biomarkers based on epigenetic analysis and apply these biomarkers to clinical oncology. Many studies on the association between RAASF1A methylation status and susceptibility to hepatitis B virus (HBV)/hepatitis C virus (HCV)-induced hepatocellular carcinoma (HCC) have reached controversial conclusions. Hence, the current review comprehensively assessed the correlation between Ras association domain family 1A (RASSF1A) methylation and the risk of the HCV/HBV-induced HCC.MethodsThe appropriated publications were extracted in EMBASE, PubMed, Web of Science, Cochrane Library, and China National Knowledge Infrastructure databases using STATA 5.0 software. The odds ratios (ORs) with 95 % confidence interval (95 % CI) of RASSF1A methylation were computed.ResultsA total of 1015 HBV/HCV-related HCC samples, 124 non-HBV/HCV-related HCC (NBNC-HCC) samples, and 1225 nontumorous controls were extracted and examined in this research. The frequency of the methylated RASSF1A in the HBV/HCV-related tumor cases displayed a significantly increased OR compared with the overall nontumor samples (OR = 19.372, 95 % CI = 11.060–33.931, P = 0.000). The frequency of the methylated RASSF1A in HBV/HCV-related neoplasm cases displayed a significantly increased OR compared with the non-HBV/HCV-related neoplasm (NBNC-neoplasm) samples (OR = 2.150, 95 % CI = 1.398–3.308, P = 0.000). Compared with normal, chronic hepatitis B or C, cirrhosis, and paracancerous samples, the pooled OR of the RASSF1A promoter methylation in the HBV/HCV-induced HCC samples was 62.785(95 % CI = 35.224–111.909), 25.07 (95 % CI = 13.85–45.36), 6.89 (95 % CI = 3.33–14.264) and 9.02 (95 % CI = 0.91–89.80), respectively. The rate of RASSF1A hypermethylation was robustly correlated with tumor size and vascular invasion, and the pooled OR was 0.346 (95 % CI = 0.210 – 0.569) and 0.081 (95 % CI = 0.022 – 0.303), respectively.ConclusionResults showed robust associations between RASSF1A gene methylation in promoter region and enhanced HBV/HCV-related HCC susceptibility, thereby revealing that RASSF1A methylation status may serve as an important indicator for HCC oncogenesis.     

Impacts of CD152 polymorphisms on cervical cancer susceptibility

AimThe objective of this study was to discuss the effect of CD152 polymorphisms rs231775, rs3087243 and rs5742909 on the susceptibility to cervical cancer.MethodsThe databases of PubMed, EMBASE, Cochrane Library, ISI Web of Science, Google Scholar Web, CNKI and Wanfang were searched for eligible studies. Chi-square-based Q test examined heterogeneity between included studies, and when P_{heterogeneity} was less than 0.05, random-effect model was used to calculate odds ratios (ORs) with their 95 % confidence intervals (95 % CIs); or else, fixed-effect model was selected. Sensitivity analysis was implemented to determine the stability of final results through removing enrolled studies one at a time and then re-obtaining overall estimates. Publication bias among included studies was checked employing Begg’s funnel plot and Egger’s test.ResultsCD152 polymorphism rs231775 decreased cervical cancer risk in total analysis under the genetic models of GG vs. AA, GG vs. AA + AG and G vs. A (OR = 0.73, 95 % CI = 0.59–0.91; OR = 0.78, 95 % CI = 0.65–0.94; OR = 0.92, 95 % CI = 0.87–0.98), and so did the polymorphism rs3087243 in total analysis under the comparisons of AA vs. GG, AA + GA vs. GG, AA vs. GG + GA, A vs. G and GA vs. GG (OR = 0.51, 95 % CI = 0.42–0.60; OR = 0.71, 95 % CI = 0.62–0.82; OR = 0.57, 95 % CI = 0.50–0.66; OR = 0.70, 95 % CI = 0.64–0.77; OR = 0.83, 95 % CI = 0.72–0.97). Besides, the polymorphism rs5742909 elevated the disease onset in total analysis under the contrasts of TT vs. CC, TT + CT vs. CC, TT vs. CC + CT, T vs. C and CT vs. CC (OR = 2.66, 95 % CI = 1.75–4.04; OR = 1.54, 95 % CI = 1.24–1.91; OR = 2.13, 95 % CI = 1.12–4.03; OR = 1.44, 95 % CI = 1.17–1.78; OR = 1.49, 95 % CI = 1.22–1.83).ConclusionCD152 polymorphisms rs231775 and rs3087243 significantly decrease the risk of cervical cancer, while rs5742909 may increase the disease risk.
