RESUMO
We aim to evaluate prostate health index as an additional risk-stratification tool in patients with Prostate Imaging Reporting and Data System score 3 lesions on multiparametric magnetic resonance imaging. Men with biochemical or clinical suspicion of having prostate cancer who underwent multiparametric magnetic resonance imaging in two tertiary centers (Queen Mary Hospital and Princess Margaret Hospital, Hong Kong, China) between January 2017 and June 2022 were included. Ultrasound-magnetic resonance imaging fusion biopsies were performed after prostate health index testing. Those who only had Prostate Imaging Reporting and Data System score 3 lesions were further stratified into four prostate health index risk groups and the cancer detection rates were analyzed. Out of the 747 patients, 47.3% had Prostate Imaging Reporting and Data System score 3 lesions only. The detection rate of clinically significant prostate cancer in this group was 15.0%. The cancer detection rates of clinically significant prostate cancer had statistically significant differences: 5.3% in prostate health index <25.0, 7.4% in prostate health index 25.0-34.9, 17.9% in prostate health index 35.0-54.9, and 52.6% in prostate health index ≥55.0 (P < 0.01). Among the patients, 26.9% could have avoided a biopsy with a prostate health index <25.0, at the expense of a 5.3% risk of missing clinically significant prostate cancer. Prostate health index could be used as an additional risk stratification tool for patients with Prostate Imaging Reporting and Data System score 3 lesions. Biopsies could be avoided in patients with low prostate health index, with a small risk of missing clinically significant prostate cancer.
RESUMO
SummaryBackground Data on the prevalence of cancer in coronavirus disease 2019 (COVID-19)-infected patients and the severe illness incidence and mortality of COVID-19 patients with cancers remains unclear. MethodsWe systematically searched PubMed, Embase, Cochrane Library, and Web of Science, from database inception to July 15, 2020, for studies of patients with COVID-19 infection that had available comorbidity information on cancer. The primary endpoint was the pooled prevalence of cancer in COVID-19 patients and the secondary endpoint was the outcomes of COVID-19-infected cancer patients with incidence of severe illness and death rate. We calculated the pooled prevalence and corresponding 95% confidence intervals (95% CIs) using a random-effects model, and performed meta-regression analyses to explore heterogeneity. Subgroup analyses were conducted based on continent, country, age, sample size and study design. FindingsA total of 107 eligible global studies were included in the systematic review. 90 studies with 94,845 COVID-19 patients in which 4,106 patients with cancer morbidity were included in the meta-analysis for prevalence of cancer morbidity among COVID-19 patients. 21 studies with 70,969 COVID-19 patients in which 3,351 patients with cancer morbidity who had severe illness or death during the studies. The overall prevalence of cancer among the COVID-19 patients was 0.07 (95% CI 0.05{bsim}0.09). The cancer prevalence in COVID-19 patients of Europe (0.22, 95% CI 0.17{bsim}0.28) was higher than that in Asia Pacific (0.04, 95% CI 0.03{bsim}0.06) and North America (0.05, 95% CI 0.04{bsim}0.06). The prevalence of COVID-19-infected cancer patients over 60 years old was 0.10 (95% CI 0.07{bsim}0.14), higher than that of patients equal and less than 60 years old (0.05, 95% CI 0.03{bsim}0.06). The pooled prevalence of severe illness among COVID-19 patients with cancers was 0.35 (95% CI 0.27{bsim}0.43) and the pooled death rate of COVID-19 patients with cancers was 0.18 (95% CI 0.14{bsim}0.18). The pooled incidence of severe illness of COVID-19 patients with cancers from Asia Pacific, Europe, and North America were 0.38(0.24, 0.52), 0.36(0.17, 0.55), and 0.26(0.20, 0.31), respectively; and the pooled death rate from Asia Pacific, Europe, and North America were 0.17(0.10, 0.24), 0.26(0.13, 0.39), and 0.19(0.13, 0.25), respectively. InterpretationTo our knowledge, this study is the most comprehensive and up-to-date metaanalysis assessing the prevalence of cancer among COVID-19 patients, severe illness incidence and mortality rate. The prevalence of cancer varied significantly in geographical continents and age. The COVID-19 patients with cancer were at-risk for severe illness and a high death rate. The European COVID-19 patients had the highest cancer prevalence among the three continents examined and were also the most likely to progress to severe illness and death. Although the Asia Pacific COVID-19 patients had the lowest cancer prevalence, their severe illness rate was similar to that of Europeans. Research in context Evidence before this studyCoronavirus disease (COVID-19) is an infectious disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), a newly discovered coronavirus, which leads to respiratory illness and can be transmitted from person to person. As the infection has become widespread, concern for the influence of COVID-19 on patients with cancer has grown. Previous studies suggest that patients with a history of active malignancy might be at increased risk for COVID-19, developing COVID-19-related complications and having a poorer prognosis. Until now, however, few studies explored the following two questions: 1) what is the estimated prevalence of cancer patients with COVID-19 infection; and 2) do COVID-19-infected cancer-patients have distinct clinical courses and worse outcomes compared with COVID-19-infected patients without cancers. The latter is based on the former to further explore the characteristics of clinical outcomes of such patients. The clarification of these two questions will greatly help to understand the relationship between COVID-19 and cancer in terms of clinical epidemiology, and thus facilitate the formulation of targeted and relevant public health policies. Added value of this studyTo our knowledge, this systematic review and meta-analysis of 107 studies is the most comprehensive and up-to-date assessing the prevalence of cancer among COVID-19 patients, the incidence of severe illness and mortality rate of COVID-19 patients with cancers. We provided a relatively accurate overall cancer prevalence among the all COVID-19 patients (7%), stratified by geographical continent, country, age, study sample size, and study design type. We also presented the pooled severe illness and mortality rates stratified by continent. European COVID-19-infected cancer patients seemed the most likely to both develop cancer and progress to severe illness and death. Implications of all the available evidenceOur findings have reinforced important considerations of clinical care and emphasized the urgent unmet needs for COVID-19 patients with cancers using the pooled prevalence, incidence of severe illness, and death rates as evidence. Also, after comparing the cancer prevalence, incidence of severe illness, and death rate of COVID-19 patients from different continents, European population may require stronger control measures than the Asia Pacific and North American populations. In the future, as more data will be available, it will be interesting to further investigate the differences of sociodemographic and climcopathological features between COVID-19-infected patients with cancer and without cancer.
RESUMO
Objective To analyze the prevalence of depression in early pregnancy, explore its possible influencing factors, and provide reference for mental health care during pregnancy. Methods A baseline survey of 9 193 early pregnant women recruited by the Chinese Pregnant Women Cohort Study (CPWCS) program was conducted. Edinburgh Postnatal Depression Scale was used to assess the depression symptoms in early pregnancy. The χ2 test and multivariable logistic regression were used to analyze the influencing factors. Results The rate of depression in early pregnant women in CPWCS was 46.50%. Multivariate analysis showed that unplanned pregnancy (OR=1.23, 95%CI: 1.12~1.35, P<0.001), passive smoking (OR=1.28, 95%CI: 1.18~1.39, P<0.001), drinking (OR=1.35, 95%CI: 1.12~1.63, P=0.002) and consumption of carbonated or sugary beverages （OR=0.80, 95%CI: 0.73~0.88, P<0.001） were risk factors for depression during early pregnancy, while enough sleep (OR=0.71, 95%CI: 0.57~0.88, P=0.002), moderate-high level of physical activity (OR=0.87, 95%CI: 0.78~0.98, P=0.023), healthy intake of vegetables and fruits（OR=0.60, 95%CI: 0.51~0.70, P<0.001), animal foods（OR=0.82, 95%CI: 0.74~0.91, P<0.001） and milk and dairy products（OR=0.81, 95%CI: 0.72~0.90, P<0.001）were protective factors. Conclusion The rate of depression was high and it was affected by many factors. It is necessary to pay more attention to depression symptoms during early pregnancy and carry out targeted psychological health care during pregnancy.
RESUMO
Objective To understand the status of economic burden of maternal health care of pregnant women in China, and to discuss the equity and accessibility of maternal health care during pregnancy among different regions and populations. Methods A total of 9 193 women during early pregnancy were recruited from the Chinese Pregnant Women Cohort Study between July 25, 2017 and November 26, 2018. Information on general condition and economic burden of maternal health care was surveyed. SPSS 25.0 software was used for statistical analysis. Results The median direct medical cost of maternity check-ups for pregnant women was 400 CNY per visit, and the median cost of lost work was 360 CNY per visit. The analysis of the results showed that the median medical expense was highest in pre-pregnant women with BMI 2 (P=0.008). The median medical expense was higher in urban residents than rural residents (Ptrend=0.003). The higher the socioeconomic status was, the higher the direct medical expense was (Ptrend=0.003). The cost of lost work was lower in pregnant women with higher socioeconomic status (P=0.025, Ptrend=0.017). In addition, the medical expense was highest in women living in the eastern part of China (P<0.001). The direct medical expenses (P=0.002) and lost-time expenses of pregnant women in the North were higher than those in the South (P=0.013). Conclusion The problem of equity and accessibility of maternal health care still existed. It is recommended that relevant departments further improve maternal health care services and build a diversified healthcare service system to ensure maternal and child health and promote eugenics.
RESUMO
Objective@#To study the relationship between exposure factors in early pregnancy and preterm birth (PB), low birth weight (LBW) and small for gestational age (SGA) of neonates.@*Methods@#A total of 3 172 pregnant women who were enrolled in the project of Chinese Pregnant Women Cohort Study-Peking Union Medical College (CPWCS-PUMC) from July 25, 2017 to July 24, 2018 and delivered before December 31, 2018 were selected as subjects in this study. The relationship between exposure factors in early pregnancy and adverse outcomes of neonatal delivery was analyzed by using binary logistic regression analysis.@*Results@#The incidence rates of PB, LBW and SGA were 4.76%, 3.53% and 5.74%, respectively. In terms of PB, the analysis results showed that the gestational weight gain (GWG) and living in northern China were protective factors, while premature rupture of membranes, gestational hypertension, dental examination or treatment within 1-3 years and family with 3-4 members were risk factors. In the respect of LBW, GWG and daily consumption of milk and dairy products were the protective factors, while premature rupture of membranes, gestational hypertension, sedentary working time more than 6 hours, dental examination or treatment within 1-3 years and passive smoking were risk factors. For SGA, baby girl, passive smoking, peanut oil consumption and unsalted taste were risk factors, while folic acid supplementation was protective factor.@*Conclusion@#The risk factors for PB, LBW and SGA were multifactorial, and relevant specific measures should be taken to reduce the occurrence of adverse neonatal outcomes.
RESUMO
Objective@#To explore oral health care behavior and related factors among women in their 1st trimester.@*Methods@#Our analysis included 7 014 women in their 1st trimester aged 16 years or above from the baseline survey of the Chinese Pregnant Women Cohort Study (CPWCS). Data on socio-demographic characteristics and oral health care behavior were collected using an electronic questionnaire. Multiple-factors Logistic regression was used to analyze factors associated with oral health care behavior.@*Results@#The results revealed that 5 134 (73.20%), 2 482 (35.39%), and 1 046 (14.91%) pregnant women brushed their teeth twice a day or more, never had an oral examination, and used special oral care products for pregnant women, respectively. The frequency of brushing teeth and oral examination was positively associated with age and annual household income. Compared to unemployed pregnant women with rural registered residences and low education levels, highly educated and employed pregnant women with city registered residences had a higher frequency of brushing teeth and undergoing oral examination. Pregnant women with depressive symptoms had a lower frequency of brushing teeth (OR=0.73, 95% CI: 0.65-0.81), while those with medical insurance underwent more frequent oral examination (OR=1.19, 95% CI: 1.02-1.39). Compared to pregnant women who were unaware of the risk of gingivitis, those who believed gingivitis to be harmful to both themselves and their fetus had a higher frequency of brushing teeth and oral examination and were more likely to use special oral care products.@*Conclusion@#Most pregnant women did not pay attention to the need for oral examinations and special oral care products. Their oral health behavior was associated with socioeconomic status, depressive symptoms, and awareness of the importance of oral health. Therefore, oral health care before and during pregnancy was required to help them improve their self-care behavior.
