Cancer mortality in Serbia, 1991-2015: an age-period-cohort and joinpoint regression analysis

Prevalence and spatial distribution characteristics of human echinococcosis: A county-level modeling study in southern Xinjiang, China

Objectives

Human echinococcosis remains an important public health problem. The aim of this study was to analyze the prevalence and spatial distribution characteristics of human echinococcosis cases in southern Xinjiang, China from 2005 to 2021.

Methods

Human echinococcosis cases were collected from the National Infectious Disease Reporting System. Joinpoint regression analysis was performed to explore the trends. Spatial autocorrelation, hot spot analysis, as well as spatial-temporal clustering analysis were conducted to confirm the distribution and risk factors.

Results

A total of 4580 cases were reported in southern Xinjiang during 2005-2021, with a mean annual incidence of 2.56/100,000. Echinococcosis incidence showed an increasing trend from 2005 to 2017 (APC = 17.939, 95%CI: 13.985 to 22.029) and a decreasing trend from 2017 to 2021 (APC = -18.769, 95%CI: 28.157 to -8.154). Echinococcosis cases had a positive spatial autocorrelation in 2005-2021 (Moran's I = 0.19, P < 0.05). The disease hotspots were located in the east and west in these areas, then returned to the east clusters, including Hejing, Heshuo, Wuqia, Atushi, Aheqi, and Yanqi Hui Autonomous County. Meanwhile, spatial-temporal analysis identified the first cluster comprised of five counties (cities): Yanqi Hui Autonomous County, Korla City, Bohu County, Hejing County, and Heshuo County. And secondary clusters 1-3 are predominantly in Wushi County, Aheqi County, Keping County, Atushi City, Wuqia County and Cele County.

Conclusions

Our findings suggest that echinococcosis is still an important zoonotic parasitic disease in southern Xinjiang, yet it showed a certain degree of spatial clustering. It is crucial to implement comprehensive prevention and control measures to effectively combat the epidemic of echinococcosis.

Predictors of Anxiety Before and After Diagnostic Procedures in Women with Abnormal Papanicolaou Smear in Cervical Cancer Screening Program

Anxiety is one of the most common causes of withdrawal from follow-up among women with abnormal Papanicolaou screening results. The purpose of this study was to investigate predictors of anxiety in women with abnormal Papanicolaou smear in cervical cancer screening program. A population-based, cross-sectional study concerning the factors related to anxiety was carried out during 2017 in a cohort of women (N = 172) with positive Papanicolaou screening test before and after diagnostic procedures (colposcopy/biopsy/endocervical curettage) at one university Clinical Center in Serbia. Women completed a socio-demographic questionnaire and scale concerning anxiety (Hospital Anxiety and Depression Scale, subscale HADS-Anxiety) immediately before and 2-4 weeks after the diagnostic procedures. Multivariate logistic regression was applied in the data analysis. In our study, 35.2% (n = 52) of women had abnormal anxiety scores before the diagnostic procedures and 40.1% (n = 69) after the diagnostic procedures. Predictors of anxiety before diagnostic procedures were family history of noncervical gynecological cancers, higher level of worry and high burden of depressive symptoms. Significant independent predictors of anxiety after diagnostic procedures in women were rural residence, tension and discomfort during medical procedures, and less satisfaction with information/support. Although there was no significant difference in the prevalence of anxiety before and after diagnostic procedures in women with abnormal Papanicolaou screening results, results of this research will enable doctors to successfully make decisions concerning timely psychological support for women with positive screening test for cervical cancer that is necessary to decrease anxiety in our population.

Identification of core carcinogenic elements based on the age-standardized mortality rate of lung cancer in Xuanwei Formation coal in China

In this study, the core carcinogenic elements in Xuanwei Formation coal were identified. Thirty-one samples were collected based on the age-standardized mortality rate (ASMR) of lung cancer; Si, V, Cr, Co, Ni, As, Mo, Cd, Sb, Pb, and rare earth elements and yttrium (REYs) were analyzed and compared; multivariate statistical analyses (CA, PCA, and FDA) were performed; and comprehensive identification was carried out by combining multivariate statistical analyses with toxicology and mineralogy. The final results indicated that (1) the high-concentration Si, Ni, V, Cr, Co, and Cd in coal may have some potential carcinogenic risk. (2) The concentrations of Cr, Ni, As, Mo, Cd, and Pb meet the zoning characteristics of the ASMR, while the Si concentration is not completely consistent. (3) The REY distribution pattern in Longtan Formation coal is lower than that in Xuanwei Formation coal, indicating that the materials of these elements in coal are different. (5) The heatmap divides the sampling sites into two clusters and subtypes in accordance with carcinogenic zoning based on the ASMR. (6) PC1, PC2, and PC3 explain 62.629% of the total variance, identifying Co, Ni, As, Cd, Mo, Cr, and V. (7) Fisher discriminant analysis identifies Ni, Si, Cd, As, and Co based on the discriminant function. (8) Comprehensive identification reveals that Ni is the primary carcinogenic element, followed by Co, Cd, and Si in combination with toxicology. (9) The paragenesis of Si (nanoquartz), Ni, Co, and Cd is an interesting finding. In other words, carcinogenic elements Ni, Co, Cd, and Si and their paragenetic properties should receive more attention.

Global burden and trends of respiratory syncytial virus infection across different age groups from 1990 to 2019: A systematic analysis of the Global Burden of Disease 2019 Study

OBJECTIVE

Understanding the global patterns of respiratory syncytial virus (RSV) is crucial for developing effective prevention and control strategies.

METHODS

Data on RSV-related burden were extracted from the Global Burden of Disease 2019. Joinpoint regression models were used to assess the global temporal trends of RSV and further stratified analyses were conducted according to the Socio-demographic Index (SDI), which is a composite measure of income, education, and total fertility. Age-period-cohort model was used to evaluate age, period, and cohort effects.

RESULTS

In 2019, the global age-standardized rate of mortality (ASMR) and disability-adjusted life years (ASR-DALYs) of RSV were 4.79/100,000 (95% uncertainty interval [95% UI]: 1.82/100,000-9.32/100,000) and 218.34/100,000 (95% UI: 92.06/100,000-376.80/100,000), respectively. The burden of RSV was higher in men than women. The highest ASMR (10.26/100,000, 3.80/100,000-20.16/100,000) and ASR-DALYs (478.71/100,000, 202.40/100,000-840.85/100,000) were reported in low-SDI region. Although mortality and DALYs rates in all age groups declined globally, the pace of decline was not uniform across age groups. Mortality rate in the elderly over 70 years surpassed that in children under 5 years in 2019.

CONCLUSION

This study highlights the need for targeted interventions to reduce the burden of RSV, particularly in low-SDI region, and among the elderly over 70 years.

Pancreatic cancer incidence and mortality trends in urban Shanghai, China from 1973 to 2017: a joinpoint regression and age-period-cohort analysis

Background and purpose

To provide a comprehensive overview of epidemiological features and temporal trends of pancreatic cancer in urban Shanghai from 1973 to 2017.

Methods

Data on pancreatic cancer in urban Shanghai were obtained through the Shanghai Cancer Registry and the Vital Statistics System. Joinpoint analysis was used to describe the temporal trends and annual percent changes (APCs) and age-period-cohort analysis were used to estimate the effects of age, period, and birth cohort on pancreatic cancer.

Results

There were a total of 29,253 cases and 27,105 deaths of pancreatic cancer in urban Shanghai over the 45-year study period. The overall average annual age-standardized incidence and mortality rates were 5.45/100,000 and 5.02/100,000, respectively. Both the incidence and mortality rates demonstrated fluctuating upward trends, with an average annual increase rate of 1.51% (APC = 1.51, P < 0.001) and 1.04% (APC = 1.04, P < 0.001), respectively. The upward trend in incidence was greater for females than for males, while the trend in mortality was seen in both sexes equally and continuously. In recent years (2013-2017), the age-specific incidence rates increased further than before, with statistically significant changes in the 35-year, 45- to 55-year and 70- to 85-year age groups (P < 0.05). The age-specific mortality rates also showed obvious upward trends, which in the 50- to 55-year, and 75- to 85-year age groups increased significantly. The results of the age-period-cohort analysis suggested significant effects of age, period, and cohort on the prevalence of pancreatic cancer.

Conclusion

The prevalence of pancreatic cancer, dramatically influenced by socioeconomic development and lifestyles, demonstrated a significant upward trend from 1973 to 2017 in urban Shanghai and underscored the necessity and urgency for additional efforts in primary and secondary prevention measures.

International patterns and trends in the brain cancer incidence and mortality: An observational study based on the global burden of disease

Background

Brain cancer is a serious issue in the global burden of diseases. This observational research aimed to assess trends of the brain cancer incidence and mortality in the world in the period 1990-2019.

Methods

Brain cancer incidence and mortality data were retrieved from the Global Burden of Disease 2019 study database. The joinpoint regression analysis was done to assess the brain cancer indicence and mortality trends: the average annual percent change (AAPC) along with its 95% confidence interval (95% CI) was calculated.

Results

In both sexes, the highest age-standardized rates of incidence and mortality were found in high-income regions (Europe and America), while the lowest were observed in the African Region. A significant rise in brain cancer incidence rates both in males and females was observed in all regions, with one exception of a significantly decreased trend only among males in the South-East Asia Region. Among countries with increased trends in incidence and mortality from brain cancer, Cuba experienced the most marked increase in both incidence (AAPC = +5.7% in males and AAPC = +5.4% in females) and mortality rates (AAPC = +5.5% in males and AAPC = +5.1% in females). Among countries that experienced a decline in brain cancer incidence and mortality, Hungary and Greenland showed the most marked decline in both sexes (equally by -1.0%).

Conclusion

Brain cancer shows increasing global incidence rates in both sexes and represents a priority for prevention and further research.

Worldwide long-term trends in the incidence of nonalcoholic fatty liver disease during 1990–2019: A joinpoint and age-period-cohort analysis

Background

Non-alcoholic fatty liver disease (NAFLD) was previously a neglected disease that is now becoming a worldwide pandemic. A better understanding of its incidence and long-term trends will help to increase public awareness of the disease and the development of future prevention strategies.

Methods

The incidence rates of NAFLD during 1990–2019 were collected from the Global Burden of Disease Study 2019 database according to the following parameters: sex, age, socio-demographic index, and geographical region. Estimated annual percentage changes and joinpoint models were used to assess the long-term trend of NAFLD, and an age-period-cohort model was used to assess the extents of the age, period, and cohort effects.

Results

Adult males, postmenopausal females, Latin American populations, and people in developing countries had a high risk of developing NAFLD. The joinpoint model indicated a new trend of increasing NAFLD incidence in 2005. Age was a risk factor affecting NAFLD incidence, with this effect increasing in more-recent periods. Younger birth cohorts had lower risks of NAFLD.

Conclusions

Recent prevention measures for NAFLD have achieved good initial results. However, it remains a high priority to increase the public awareness of this condition, develop its diagnostic criteria, identify cost-effective screening methods, and seek policy support to act against NAFLD, which will be a major public health problem in the future.

Predictors of depressive symptoms before and after diagnostic procedures in women with abnormal Pap smear attending cervical cancer screening programme in Serbia

OBJECTIVES

Receipt of a positive Papanicolaou screening result and subsequent referral for diagnostic tests can cause psychological stress. Still, not enough is known about depression before and after the diagnostic test in these women. The aim of this study was to determine the burden and predictors of depressive symptoms prior to and after diagnostic investigations in women who had received a positive Papanicolaou screening result.

METHODS

This was a cross-sectional study. Study cohort comprised women who received an abnormal Papanicolaou screening result. Women completed the socio-demographic questionnaire and 'The Center for Epidemiologic Studies Depression, CES-D' questionnaire before and after diagnostic tests (colposcopy/biopsy/endocervical curettage) to assess factors related to depression.

RESULTS

No significant difference was noted in the frequency of depressive symptoms (CES-D score ≥ 16) before and after diagnostic investigations, but the mean score on CES-D scale showed a significant difference before and after diagnostic investigations (13.98 ± 9.56 and 12.74 ± 9.15, respectively). A significant predictor of depression before diagnostic investigations was spontaneous abortion, whereas family history of other gynaecological cancers was a predictor of depression after diagnostic investigations.

CONCLUSIONS

Our findings could contribute to improving the rates of cervical cancer screening, by identifying women at risk for depression before and after investigations.

Application of metalloporphyrin sensitizers for the treatment or diagnosis of tumors

At present, metalloporphyrin compounds demonstrate three main uses as anticancer sensitizers: (1) photosensitizers, (2) photothermal conversion agents, and (3) ultrasound sensitizers. Developing efficient sensitizers for cancer with excellent controllability and biocompatibility is an important goal of oncology medicine. Because of the different structural diversity of anticancer sensitizers, such sensitizers are used for treating cancers by employing a variety of tumor treatment methods such as mature photodynamic therapy, commonly used clinically photothermal therapy and promising sonodynamic therapy. Among the many sensitizers, metalloporphyrin-complex sensitizers attract wide attention due to their excellent performance in tumor treatment and diagnosis. This review briefly describes some metalloporphyrin anticancer drugs and diagnostic agents related to photodynamic, photothermal and sonodynamic therapy, and discusses the roles of metal atoms in these drugs.

Depression before and after diagnostic procedures among women with abnormal finding of Papanicolaou screening test

Background

Some studies did find significant differences in the level of depression of women while undergoing diagnostic evaluation of an abnormal Papanicolaou screening smear, but findings were not consistent. This study aimed to assess prevalence and correlates of depression in women with abnormal cervical screening results before and after diagnostic procedures.

Methods

A cross‐sectional study was carried out during 2017 in a cohort of women with positive Papanicolaou screening test before and after diagnostic procedures (colposcopy/biopsy/endocervical curettage) at the university Clinical Centre Kragujevac, Serbia. Women completed a questionnaire about demographics, lifestyle, and other factors of interest. Also, questionnaire “Hospital Anxiety and Depression Scale” (HADS) was used immediately before and 2–4 weeks after the diagnostic procedures: a score of ≥8 on HADS‐D and HADS‐A subscales indicated depression and anxiety, respectively. Multivariate logistic regression was applied in the data analysis.

Results

The study comprised 172 women, giving a response rate of 72.3%. The mean age of the participants was 47.8 ± 11.1 years (range 23–65). The frequency of depressive symptoms was significantly higher after diagnostic procedures (48.3%) than before diagnostic procedures (37.2%) (p = 0.038). Before diagnostic procedures, older age (OR = 1.60; 95% CI = 1.09–2.34; p = 0.017), and level of anxiety according to the HADS‐A subscale (OR = 1.61; 95% CI = 1.38–1.88; p < 0.001) were significant independent predictors of depression. After diagnostic procedures, significant independent predictors of depression were urban place of residence (OR = 0.12; 95% CI = 0.03–0.47; p = 0.002) and level of anxiety according to the HADS‐A subscale (OR = 1.85; 95% CI = 1.54–2.21; p < 0.001).

Conclusion

Our study showed that older age, rural residence, and anxiety play a role in shaping the risk of depression among women undergoing additional diagnostic procedures after receiving an abnormal Papanicolaou screening result.

Cancer of unknown primary - incidence, mortality trend, and mortality-to-incidence ratio is associated with human development index in Central Serbia, 1999-2018: Evidence from the national cancer registry

OBJECTIVES

The aim was to estimate the trend of incidence, mortality and mortality-to-incidence ratio (MIR) in Central Serbia in 1999-2018 and its possible association with the human development index (HDI).

METHODS

In this study, cancer of unknown primary (CUP) was included as C77-C80 codes. Trend analysis was performed in the Joinpoint Regression Programme version 4.8.0.1. HDI combines life expectancy, educational attainment and gross national income. HDI values for Serbia are extracted from the global bank site.

RESULTS

Joinpoint regression analysis of the age-standardised incidence rate of CUP showed a significantly increasing trend with annual percent change (APC) of 8.5% (95% confidence interval [CI] 3.0-14.3%) in males and 7.8% (95%CI 2.7-13.2) in females. The age-standardised mortality rate of CUP showed a significantly decreasing trend with APC of -1.7% (95%CI -2.8 to -0.5%) in males and -1.4% (95%CI -2.7 to -0.1%) in females. MIR showed a significantly decreasing trend with APC of -9.3% (95%CI -14.6 - -3.6%) in males and -7.1% (95%CI -10.5% to -4.2%) in females. The linear regression showed significant inverse association among HDI and the MIR of CUP in males (r²  = 0.464, p = 0.002) and in females (r²  = 0.612, p < 0.001).

CONCLUSIONS

Decline of MIR was associated with HDI, suggesting that CUP prognosis follows socio-economic status.

Cancer death and potential years of life lost in Feicheng City, China: Trends from 2013 to 2018

This study aimed to evaluate the impact of cancer-related mortality on life expectancy in Feicheng City.We extracted the death records and population data of Feicheng City from 2013 to 2018 through the Feicheng Center for Disease Control and Prevention. The mortality, premature mortality, cause-eliminated life expectancy, potential years of life lost (PYLL), average potential years of life lost (APYLL), annual change percentage (APC), and other indicators of cancer were calculated. The age-standardized rates were calculated using the sixth national census (2010).From 2013 to 2018, the mortality rate of cancer in Feicheng City was 221.55/100,000, and the standardized mortality rate was 166.37/100,000. The standardized mortality rate increased from 2013 to 2014 and then decreased annually. The premature mortality of cancer was 8.98% and showed a downward trend (APC = -2.47%, t = -3.10, P = .04). From 2013 to 2018, the average life expectancy of residents in Feicheng City was 78.63 years. Eliminating the impact of cancer, life expectancy could increase by 3.72 years. The rate of life loss caused by cancer in men was higher than that in women. The total life loss caused by cancer deaths was 126,870.50 person-years, the potential life loss rate was 22.51‰, and the average potential life loss was 13.30 years. The standardized potential years of life lost rate showed a downward trend (APC = -2.96%, t = -3.72, P = .02), and APYLL decreased by 1.98% annually (t = -5.44, P = .01). The top 5 malignant tumors in APYLL were leukemia, breast cancer, brain tumor, liver cancer, and ovarian cancer.Lung cancer, esophageal cancer, female breast cancer, and childhood leukemia have a great impact on the life expectancy of residents in Feicheng City. Effective measures need to be taken to reduce the disease burden of malignant tumors.

Trends of Stomach Cancer in Central Serbia

Somach cancer is the third most common cause of cancer-related deaths worldwide. The objective of the paper was to analyze the incidence and mortality trends of stomach cancer in Central Serbia in the period between 1999-2017. Materials and Methods: trends and annual percentage change (APC) of the incidence and mortality rate with corresponding 95% confidence intervals (CI) were calculated by joinpoint regression analyses. The optimal number of Joinpoints was identified using the Monte Carlo permutation method. The trend was considered to be significantly increasing (positive change) or decreasing (negative change) when the p-value was below 0.05 (p < 0.05). Results: the total number of new cases was 16,914 (10,873 males and 6041 females) and the total number of mortality cases was 14,790 (9348 in and 5442 in females). Almost one third (30.8%) of new cases were registered in the 60-69-year age group, and new cases were significantly more frequent in males than in females (30.8% vs. 29.02%, p < 0.001). Joinpoint regression analysis showed a significant decrease of incidence trend in females during the 2000-2015 period with APC of -2.13% (95% CI: -3.8 to -0.5, p < 0.001). An insignificant decrease in incidence trend was in males with APC of -0.72% (95% CI: -2.3 to 0.9, p = 0.30). According to the joinpoint analysis, a significant decrease of mortality trends both in males during 2000-2015 with APC of -2.21% (95% CI: -1.6 to -7.5, p ≤ 0.001 and in females, during the same period, with APC of -1.75% (95% CI: -2.9 to -0.6, p < 0.001) was registered. From 2015 to 2017, a significant increase of mortality was registered with APC of 44.5% (95% CI: from 24.2 to -68.1, p ≤ 0.001) in females and in males with APC of 53.15% (95% CI: 13.5 to -106.6, p ≤ 0.001). Conclusion: a significant decrease of stomach cancer incidence trend in females and insignificant decrease of incidence trend in males were determined in Central Serbia. Based on presented results, the mortality trend decreased significantly both in males and in females during 2000-2015, and from 2015 to 2017 we recorded a significant increase in mortality in both sexes. We found significantly more new cases in women than in men in the age group of 40-49, and the mortality of stomach cancer was significantly more frequent among females compared to males in the age groups 30-39, as well as in the 50-59 age group. There is a need for improving recording and registration of new cases of stomach cancer, especially in females. Urgent primary and secondary preventive measures are needed-introducing stomach cancer screening and early detection of premalignant changes. Urgent primary and secondary preventive measures are needed.

Internal consistency and validity of the Hospital Anxiety and Depression Scale (HADS) in women with abnormal Pap smear in Serbia

Receiving a report of an abnormal finding of Pap screening test in women often leads to anxiety and depression. The purpose of this study was to investigate the construct validity and internal consistency reliability of the Serbian version of the Hospital Anxiety and Depression Scale (HADS) in women with abnormal Pap smear results. In 2017, a cross-sectional study was done involving 142 consecutive women attending cervical cancer screening who had received abnormal Pap smear results at one University clinical center in Serbia. We used exploratory factor analysis to establish the structure of the HADS and Cronbach's alpha coefficient was used for assessing the internal consistency. In our study, the HADS demonstrated high internal consistency, for both subscales (Cronbach's alpha coefficient for subscale Anxiety was 0.862, and for subscale Depression was 0.851). The intra-class correlation coefficients for the two components were significant (0.860 and 0.843, p < .001). Principal component analysis with Oblimin rotation indicated a two-factor structure that explained 56.4% of variance. In conclusion, the Serbian version of the HADS showed satisfactory internal consistency reliability and construct validity and could be useful as a screening questionnaire for the assessment of anxiety and depression among women with abnormal Pap smear results.

An Overview of Pharmacological and Non-Pharmacological Treatment as a Useful Tool for the Protection from Cardiotoxicity of Antineoplastic Drugs

Unfortunately, in patients with cancer disease, clinical application of antineoplastic drug results in severe side effects of cardiotoxicity.

We aim to review the research focused on elimination or reduction of antineoplastic drug-induced cardiotoxicity without affecting its anticancer efficacy by different agens.

This study is based on pertinent papers that were retrieved by a selective search using relevant keywords in PubMed and ScienceDirect. Based on mentioned purpose, various strategies were investigated and proposed, and thousands of compounds were screened. The literature mainly focusing on drugs, natural products and herb extracts with therapeutic efficacies as well as non-pharmacological treatment against differently induced cardiotoxicity during treatment in patients with cancers.

Larger future studies are necessary to reach a point of secure cytostatic therapy, improved patient survival and quality of life. Until that moment, baseline and serial cardiac evaluation is recommended to facilitate early identification and treatment of cardiotoxicity.

Reliability and validity of the Center for Epidemiologic Studies Depression (CES-D) scale in Serbian women with abnormal Papanicolaou smear results

OBJECTIVES

Cervical cancer ranks as the second most frequent cancer among women in Serbia. Organized screening for detection of cervical cancer was introduced in Serbia in 2013 and provided free of charge in all state health facilities. Studies have shown that depression frequently follows the notification of abnormal findings on the Papanicolaou (Pap) screening test. The aim of this study was to examine the reliability and validity of the Center for Epidemiologic Studies Depression (CES-D) scale among women in Serbia receiving a report of abnormal cytology.

METHODS

This population-based study used cross-sectional, self-reported data involving 198 consecutive women attending cervical cancer screening who had received abnormal Pap smear results. All participants completed the socio-demographic questionnaire and CES-D scale. Reliability of the CES-D scale was assessed by internal consistency reliability (measured with standardized Cronbach's coefficient α). Exploratory factor analysis was done using Promax rotation.

RESULTS

The overall Cronbach's α coefficient of the CES-D scale was 0.865, while the Cronbach's α coefficients for the subscales Depressed affect, Somatic complaints, Positive affect, and Interpersonal relationship were 0.885, 0.802, 0.851, and 0.593, respectively. Principal component analysis with Oblimin rotation indicated four main components that explained 62.0% of variance. Over one-quarter (28.8%) of the participants scored above the cut point (≥16) on the CES-D scale. The mean score for depressive symptoms was 13.0 for the study sample.

CONCLUSIONS

The Serbian version of the CES-D scale proved to be a valid and reliable instrument for identifying patients with depressive symptoms among women with abnormal Pap smear results.

Psychological distress among women with abnormal pap smear results in Serbia: Validity and reliability of the Cervical Dysplasia Distress Questionnaire

Background

Receiving report of an abnormal finding from a Pap screening test in women often leads to psychological distress.

Objectives

The purpose of this study was to assess the reliability and validity of the Cervical Dysplasia Distress Questionnaire (CDDQ) among women in Serbia.

Methods

In 2017, we conducted a cross-sectional study involving 154 consecutive women attending cervical cancer screening who had received abnormal Pap smear results.

Results

Reliability assessment showed good internal consistency for all CDDQ subscales (Tension and discomfort: Cronbach’s α = 0.844; Embarrassment: α = 0.864; Sexual and reproductive consequences: α = 0.867; and Health consequences: α = 0.913). The test-retest reliability showed that the correlation coefficients (between 0.805 and 0.983) were significant at the 0.01 level for all of the Serbian CDDQ subscales. Principal Axis Factoring with Direct Oblimin rotation indicated four main components that explain 55.0% of variance.

Conclusion

The Serbian version of the CDDQ scale is a valid and reliable instrument for the assessment of psychological distress among women with abnormal Pap smear results.

Changing trends of adverse pregnancy outcomes with maternal age in primipara with singleton birth: A join point analysis of a multicenter historical cohort study in China in 2011-2012

INTRODUCTION

Adverse pregnancy outcomes are related to two opposite maternal factors, youth and aging. However, the change in trend of specific outcomes with childbearing age is unknown. The aim of this study was to investigate the changing trend of various maternal and neonatal outcomes with maternal age from 17 to 44 years.

MATERIAL AND METHODS

Data were extracted from the medical records from 2011-2012 of 39 public hospitals of 14 cities in China. The eligibility criteria were primiparity and singleton birth. Join point regression analysis was used to estimate the percent change per year of age (PCA) to explore the trends of adverse pregnancy outcomes with regard to maternal age and to identify the join point of maternal age when the trend was changed.

RESULTS

A total of 89 171 women were eligible for analysis. There were four categories of trend styles. Continuously increasing trends were linear for placenta previa (PCA, 0.1%), placenta implantation (PCA, 0.09%) and postpartum hemorrhage (PCA, 0.22%), and nonlinear for gestational diabetes mellitus with one join point of 23 years (PCA, 0.17% and 0.71%) and cesarean section with four join points of 25, 28, 31 and 36 years (PCA, 1.39%, 0.34%, 1.51%, 3.49% and 0.94%). Continuously decreasing trends were linear for intrahepatic cholestasis (PCA, -0.02%) and nonlinear for anemia with one join point of 28 years (PCA, -0.49% and -0.04%). The bidirective trends were downward to upward for preterm birth (PCA, -2.93%, -0.36% and 0.38%), hypertension in pregnancy (PCA, -0.09%, 0.47%), low birthweight (PCA 0.51% and 0.38%), low 1-minute Apgar score (PCA, -0.28% and 0.07%), low 5-minute Apgar score at (PCA, -0.10% and 0.06%) and neonatal intensive care unit admission (PCA, -1.92%, -0.07% and 0.12%) with a nadir age of 28 years. The bidirective trend was upward to downward for macrosomia (PCA, 0.39% and -0.11%), with a peak age of 30 years.

CONCLUSIONS

The changes in the trend of specific outcomes were different with maternal age, which means that youth, aging or both could affect the outcomes.

TP53 and DNA-repair gene polymorphisms genotyping as a low-cost lung adenocarcinoma screening tool

AIM

TP53 and DNA repair polymorphisms have been proposed as cancer risk factors. This study evaluated the usability of TP53 Arg72Pro single-nucleotide polymorphism, X RCC1 Arg399Gln and RAD51 G135C as a low-cost lung adenocarcinoma screening tool.

PATIENTS AND METHODS

This case-control study included 78 atients with lung adenocarcinoma and 79 healthy matched controls. TP53, XRCC1 and RAD51 genotyping was done by PCR followed by restriction length polymorphism. Descriptive analyses included genotype and allelic frequencies and deviations of the frequencies from those expected under Hardy-Weinberg equilibrium were assessed using the χ² test. The OR and 95% CIs were calculated as an estimate of relative risk, with significance set at p value <0.05.

RESULTS

The TP53 codon 72 Pro allele and the XRCC1 codon 399 Arg allele in a homozygous state were associated with lung adenocarcinoma (p=0.037; OR (95% CI) 2.42 (1.10 to 5.31)), that is, p=0.037; OR (95% CI) 2.16 (1.08 to 4.33), respectively. Also, carriers of the TP53 codon 72 Pro allele and the XRCC1 codon 399 ArgArg genotype older than 50 showed an even higher risk of developing lung adenocarcinoma (p=0.03 in both cases).

CONCLUSIONS

The TP53 codon 72 Arg allele and XRCC1 codon 399 Gln allele are likely to have a protective effect against lung adenocarcinoma, especially in individuals older than 50 years of age. XRCC1 and TP53 genotyping might be a useful low-cost tool for evaluating individual lung cancer risk, leading to earlier detection and management of this disease.
