Objective: The aim of this study was to identify the relationship between children's age and the incidence of unintentional injuries, and giving some basic data on the guidance for the prevention of unintentional injuries in children aged 0 to 18 years in China.Methods: The literatures on the incidence of unintentional injury in children included in China from 2008 to 2018 were analyzed by meta-analysis method. The data were retrieved according to the guidance of Cochrane Systematic review. A meta-analysis was carried out on homogeneous studies, and then subgroup analysis was conducted according to age group. Publication bias was also evaluated. Stata software (version 15.0) and SPSS software (version 18.0) were used to analyze the gathered information. Results: A total of 3，303 related pieces of literature were reviewed. Of the 37 that met the inclusion criteria. The meta-analysis showed that total sample sizes were 77，023, and the pooled incidence of unintentional injury is 20%, 95%CI (17%-23%), (P< 0.001). Subgroup analysis showed the following results: the incidence are 15%, 23%, 20% and 20% for aged in “0-2”, “3-5”, “6-11”, “12-18” subgroups, respectively. However, the trend of decreased incidence of unintentional injury with older age in children was not significant.Conclusions: The pooled incidence of unintentional injuries in children is high. Based on accessible literature, the incidence between different age subgroup were not statistically significant. We should pay attention to the incidence of unintentional injuries in children of all age subgroups.

The Relationship

This systematic review aimed to find attitudes toward Altruistic and Game-playing love styles across individualistic and collectivistic cultures. Addressing major moderators concerning Altruistic and Game-playing love styles are the secondary objectives of this review. This review included 102 articles comprising samples from 37 countries (N = 41997). The findings of this meta-analysis show that there is a collectivistic and individualistic difference in Game-playing but not in the Altruistic love style. Collectivistic and individualistic cultures, on average, demonstrate the same perception concerning the Altruistic love style, whereas collectivistic culture shows the Game-playing love style more strongly. To explain the role of moderators in key measures, the subgroup analysis and meta-regression show that both Game-playing and Altruistic love styles decline by increasing the length of the relationship. Likewise, having children affects these love styles such that the Altruistic love style is improved, and the Game-playing love style is reduced by the presence of children in families.

The Relationship

The objective of this study is to explain inconsistencies in the relationship between depression and all-cause mortality by performing a reassessment of the included studies of previous systematic reviews. We assessed study-level methodological variables with a focus on sample size and follow-up period, measurement and classification of depression, and model adjustment. We included the constituent studies of fifteen systematic reviews on depression and mortality, yielding 488 articles after the removal of duplicates. 333 studies were extracted, 40 of which used data that overlapped with other included studies. We included 313 estimates from 293 articles in the meta-analysis with a total sample of 3,604,005 participants and over 417,901 deaths. We identified a pronounced publication bias favoring large, positive associations in imprecise studies. Several factors moderated the relationship between depression and mortality. Most importantly, the 16 estimates adjusting for at least one comorbid mental condition (Pooled Effect: 1.08; 95% CI: 0.98-1.18), and the fraction of 8 of those estimates also adjusting for health variables (e.g., smoking, alcohol use, or physical inactivity; Pooled Effect: 1.04; 95% CI: 0.87-1.21), reported considerably smaller associations than the 204 unadjusted estimates (Pooled Effect: 1.32; 95% CI: 1.28-1.36). The sizable relationship of depression and mortality reported in previous systematic reviews is largely based on low-quality studies; controlling for important covariates attenuates the association considerably. Higher quality studies are needed based on large community samples, extensive follow-up, adjustment for health behaviors and mental disorders, and time-to-event outcomes based on survival analysis methodology.

Background: As society ages, the incidence of osteoporosis increases. In several studies, cadmium (Cd) is thought to be related to osteoporosis. However, there are conflicting reports about the relationship between Cd and the risk of osteoporosis and osteopenia. Therefore, the purpose of this meta-analysis was to explore the relationship between Cd and osteoporosis and osteopenia.Methods: Through a review of the literature, articles published in PubMed as of December 2020 were identified and the references of related publications and reviews were reviewed. Ultimately, 17 eligible articles were selected to determine the relationship between blood and urine Cd concentrations for the risk of osteoporosis or osteopenia. In this study, we performed a classification analysis, heterogeneity test, subgroup analysis, and evaluated publication bias.Results: A total of 17 studies were included, including seven on blood Cd and 10 on urine Cd. By combining the odds ratio (OR) and 95% confidence interval (CI) for the lowest and highest categories, the odds ratio of blood Cd concentration that increased the risk of osteoporosis or osteopenia was OR 1.21 (95% CI: 0.84–1.58) and that of urine Cd concentration that increased the risk of osteoporosis or osteopenia was OR 1.80 (95% CI: 1.42–2.18), and the results of the subgroup analysis were also consistent.Conclusions: Our research indicates that while urine cadmium (Cd) concentration may be related to increased risk of osteoporosis and osteopenia, blood Cd concentration may not. Therefore, compared to blood Cd concentration, urine Cd concentration may be more reliable as a risk factor for osteoporosis and osteopenia. This result should be interpreted with caution. Currently. research on the relationship between Cd concentration and osteoporosis and osteopenia is limited, thus, further large, high-quality prospective studies are required to elucidate the relationship between Cd concentration and osteoporosis and osteopenia.

4091 Background: The relationship between Helicobacter pylori (H.pylori) and hepatocellular carcinoma (HCC) was first proposed in 1994. Since then, several studies have been performed to explore the association. The role of Hepatitis C (HCV) viruses coexisting with H.pylori in causing HCC was also studied. With the emergence of data in this regard, a causal relationship has been postulated, but not confirmed, and hence the relationship remains controversial. Our meta-analysis aims to summarize the research on this topic and investigate if there exists a relationship between H. pylori infection and the development of HCC and if the presence of HCV along with H.pylori plays a role in liver carcinogenesis. Methods: Following PRISMA guidelines, we performed a systematic review of all relevant studies published in the literature using keywords “Helicobacter pylori” and “Hepatocellular carcinoma” on major literature databases, including PubMed, EMBASE, Web of Science, and Cochrane controlled trials register. A total of 656 studies were identified between 1994 to March 2020, out of which 26 studies qualified under our selection criteria. Patients positive for HCC are included as cases and patients that did not have HCC under control group. In both groups, H.pylori positive patients and their HCV status, was identified. Results: Out of the 26 studies included in the final analysis, the prevalence of H. pylori infection was 64.78% (561 of 866) amongst HCC cases and 47.92% (1718 of 3585) in the non-HCC control group. The summary odds ratio for the association of H. pylori infection with the risk for HCC using the random-effects model was determined to be 4.75 (95% CI, 3.06-7.37), I²=63%. Subgroup analysis to determine the odds of developing HCC in the presence of H.pylori and HCV coinfection, was 13.97 (95% CI, 3.94-49.61), I²=81%. Whereas, the odds of developing HCC in the presence of only HCV without H.pylori was found to be 2.21 (0.70-6.94), I²=79. Subgroup analysis by study design showed no significant difference between the study groups (P= 0.5705). Conclusions: Our meta-analysis showed a positive association between H. pylori infection and the development of HCC. It showed a significantly higher risk of developing HCC in the presence of HCV infection along with H.pylori. Further prospective cohort studies are needed to prove the causal relationship, especially in cases of Hepatitis B, C coinfection, and cirrhotic patients.[Table: see text]

The Impact

Previous meta-analyses were conducted during the initial phases of the COVID-19 pandemic, which utilized a smaller pool of data. The current meta-analysis aims to provide additional (and updated) evidence related to the psychological impact among healthcare workers. The search strategy was developed by a medical librarian and bibliographical databases, including Medline, Embase, CINAHL, PsycINFO, and Scopus were searched for studies examining the impact of the COVID-19 pandemic on the psychological health of healthcare workers. Articles were screened by three reviewers. Heterogeneity among studies was assessed by I2 statistic. The random-effects model was utilized to obtain the pooled prevalence. A subgroup analysis by region, gender, quality of study, assessment methods, healthcare profession, and exposure was performed. Publication bias was assessed by Funnel plot and Egger linear regression test. Sixty-five studies met the inclusion criteria and the total sample constituted 79,437 participants. The pooled prevalence of anxiety, depression, stress, post-traumatic stress syndrome, insomnia, psychological distress, and burnout was 34.4%, 31.8%, 40.3%, 11.4%, 27.8%, 46.1%, and 37.4% respectively. The subgroup analysis indicated higher anxiety and depression prevalence among females, nurses, and frontline responders than males, doctors, and second-line healthcare workers. This study highlights the need for designing a targeted intervention to improve resilience and foster post-traumatic growth among frontline responders.

The Relationship

Although prior research is congested with constructs intended to capture consumers’ dispositions toward globalization and global/local products, their effects appear to replicate with difficulty, and little is known about the underlying theoretical mechanisms. This investigation revisits the relationship between prominent consumer dispositions (consumer ethnocentrism, cosmopolitanism, global/local identity, globalization attitude) and perceived brand globalness as determinants of consumer responses to global brands. Drawing on selective perception and social identity theories, the authors consider several theory-based model specifications that reflect alternative mechanisms through which key consumer dispositions relate to brand globalness and affect important brand-related outcomes. By employing a flexible model that simultaneously accounts for moderating, mediating, conditional, and direct effects, we empirically test these rival model specifications. A meta-analysis of 264 effect sizes obtained from 13 studies with 23 unique data sets and a total sample of 1,410 consumers raises concerns regarding the (potentially overstated) utility of consumer dispositions for explaining consumer responses to global brands. It also reveals a need for further conceptual contemplation of their function in international consumer research and managerial practice.
