Previous observational studies suggested that hepatitis B virus (HBV) preS mutation plays an important role in the existence of HBV‐related hepatocellular carcinoma (HCC). However, the results are still debatable. With an increasing number of studies about this topic, this study employed a meta‐analysis to identify the association between HBV preS mutation and HCC risk. We searched for eligible studies from PubMed, ProQuest, CINAHL, ScienceDirect and Springer databases to assess the association between HBV mutation and HCC risk. This meta‐analysis was conducted using RevMan 5.3 to provide pooled estimate for odds ratio (ORs) with 95% confidence intervals (95% CIs). Twenty‐one clinical studies were included in this meta‐analysis study which consisted of 1738 participants with HBV‐related HCC and 3740 HBsAg‐positive patients without HCC. All studies used samples of Asian population. PreS deletion was the most common mutation found in all studies. We found that ORs of HBV overall preS deletion was associated with HCC (OR = 3.28; 95% CI = 2.32‐4.65; P < .00001; random‐effects model). Each preS1 and preS2 deletion was associated with increased risk of HCC, with OR 2.42 (95% CI = 1.25‐4.68, P = .008) and 3.36 (95% CI = 2.04‐5.55, P < .00001), respectively. PreS2 start codon mutation was also significantly associated with HCC risk (OR = 2.47; 95% CI: 1.15‐5.27; P = .02; random‐effect model). The result of this meta‐analysis suggested that HBV preS deletion (all, preS1 and preS2) and preS2 start codon mutation might contribute to the increased risk of HBV‐related HCC.

This study determined community knowledge, attitudes, and practices after COVID-19 socialization in Rambipuji and Suci Village, Jember District, East Java, Indonesia. This study used the analytic observational design study. As many as 40 people were given socialization about COVID-19 by gathering and online. The questionnaires were completed in two parts included before-socialization and after-socialization. The questionnaire data were analyzed descriptively by calculating frequency, percentage, and inferential statistics by t-test, Spearman correlation, and chi-square test. The data analysis used IBM SPSS version 23 software. The mean and standard deviation of percentage of knowledge pre-test, knowledge post-test, high attitude, moderate attitude, low attitude, very high practice, high practice, sufficient practice, and low practice were 58.33 ± 30.97, 77.70 ± 22.52, 62.5±21.7, 31±22.2, 6.5±17.1, 65±13.8, 32.3±13.8, 1.25±2.4, 1.25±1.8, respectively. Knowledge pre-test and post-test correlated 0.819 (p=0.001) and a t-test with p=0.003. Attitudes and practices correlated with p=0.001. Socialization of COVID-19 was useful to improve the community knowledge, attitudes, and practices in Rambipuji and Suci Village, Jember District, East Java, Indonesia that could prevent the transmission and inhibit the spread of the COVID-19 pandemic in Indonesia. Furthermore, continuous encouragement of COVID-19 socialization in wide areas was recommended.

Background Research focusing on the relationship between five types of tumor necrosis factor-alpha (TNF-α) SNPs and the risk of hepatocellular carcinoma (HCC) were still controversial. Hereby, we performed a meta-analysis to determine the association between TNF-α promoter SNPs: -1031 T/C, − 863 C/A, − 857 C/T, − 308 G/A, and − 238 G/A with HCC risk. Methods We interrogated articles from journal database: PubMed, Pro-Quest, EBSCO, Science Direct, and Springer to determine the relationship between five types of SNPs in TNF-α gene with HCC risk. RevMan 5.3 software was used for analysis in fixed/random effect models. Results This meta-analysis included 23 potential articles from 2004 to 2018 with 3237 HCC cases and 4843 controls. We found that SNP − 863 C/A were associated with a significantly increased HCC risk (A vs C, OR = 1.31, 95% CI = 1.03–1.67). Similar results were obtained in − 857 C/T (TT/CT vs CC, OR = 1.31, 95% CI = 1.06–1.62), − 308 G/A (AA vs GG, OR = 3.14, 95% CI = 2.06–4.79), and − 238 G/A (AA vs GG, OR = 3.87, 95% CI = 1.32–11.34). While no associations were observed between SNP TNF-α − 1031 T/C and HCC risk. Conclusions The present meta-analysis showed that TNFα SNPs -863C/A, − 857 C/T, − 308 G/A, and − 238 G/A were associated with the risk of HCC.

Introduction: Anemia in pregnant women is a factor that directly affects the incidence of LBW and can be measured to determine nutritional status during pregnancy. This research is to determine the association of infant birth weight in mothers with maternal anemia at Public Health Center working area in Surabaya.Methods: This research was a cross-sectional approach The sample of this research were 75 pregnant women at Dupak Public Health Center in Surabaya City in 2017 taken by total sampling technique. The data used was taken from the 2017 mother cohort book.Results: The incidence of LBW at Dupak Public Health Center Surabaya working area in 2017 was 12 people (16%). The incidence of anemia at Dupak Public Health Center Surabaya working area in 2017 was 38 people (50.7%). The correlation between LBW and anemia in pregnancy using Chi-Square was p = 0.496.Conclusion: There was no correlation between maternal anemia and LBW There are other factors that can affect the incidence of LBW, such as body weight and maternal height, the number of parity, a short pregnancy distance, and the existence of problems in the history of previous pregnancy and childbirth.
