Frequency of polymorphisms in the CYP2C9, VKORC1, and CYP4F2 genes related to the metabolism of Warfarin in healthy donors from Cali, Colombia.
Alleles in the VKORC1, CYP2C9, and CYP4F2 genes can influence Warfarin dose requirement. We aimed to determine the frequency of the polymorphisms in these genes in healthy individuals from Cali, Colombia. Observational study where total blood was collected from 107 healthy donors who attended a higher educational institution in Cali, Colombia. ⋯ Both frequencies found in the VKORC1 and CYP2C9 alleles were similar to the ones reported for Latin Americans of European and Native American Ancestry. VKORC1*2 allele, the main genetic contributor to Warfarin dosing requirement, was the variant with the highest frequency (74.8% subjects, with a frequency of the alternative allele (A) of 50%). Our findings provide researchers with a greater insight regarding the frequency of common polymorphisms that affect anticoagulation treatment in the Cali (Colombia) population.

This retrospective study aims to identify the single nucleotide polymorphisms (SNPs) of 5,10-methylenetetrahydrofolate reductase (MTHFR) (C677T, A1298C), methionine synthase reductase (MTRR) (A66G) and ethnic distribution characteristics in pregnant women, and to explore the risk correlation with folate metabolism. The demographic data of 8735 pregnant women aged 15 to 47 years were retrospectively analyzed, and peripheral blood samples were collected and tested. Reverse transcription-quantitative polymerase chain reaction was applied to determine the genotype and allele frequency of MTHFR C677T, A1298C and MTRR A66G in blood samples. ⋯ The frequency distribution of SNPs in different ethnic groups revealed that the frequency of CT genotype among the MTHFR C677T locus, AA genotype among the MTHFR A1298C locus and the MTRR A66G locus was the highest in Han, Buyi, Miao and Dong ethnic groups. The results of logistic regression analysis showed that the Han, Buyi, Miao and other ethnic groups (including Yi, Bai, Zhuang, Chuanqing) had the possibility of increasing the risk levels of folate metabolism. The CC genotype of MTHFR C677T (adjusted OR = 2.46, 95% CI: 2.14-2.84, P < .001) and the AG genotype of MTRR A66G (adjusted OR = 1.89, 95% CI: 1.61-2.22, P < .001) were significantly related to the risk levels of folate metabolism, which is an independent risk factor for the susceptibility of folate metabolism.

The number of hospital visits with cervical cancer as the chief complaint among South Korean women aged 20 to 39 has increased by 1.2 times between 2016 and 2020, indicating a need for active screening for the disease. This study aimed to investigate the status of the Papanicolaou (Pap) test and identify factors influencing Pap test experience among South Korean women aged 20 to 39 years. An online questionnaire survey was conducted over 5 days starting from November 19, 2021. ⋯ Pap test attitude, Pap test self-efficacy, cervical cancer knowledge, HPV knowledge, and cancer prevention behavior scores were significantly higher in the Pap test experience group than in the no Pap test experience group (P < .05). Logistic regression analysis showed that experience of coitus (odds ratio [OR] = 10.46, 95% confidence interval [CI]: 4.54-24.11), marital status (OR = 5.96, 95% CI: 2.25-15.77), awareness of the National Cancer Screening Program (OR = 4.39, 95% CI: 1.66-11.58), HPV vaccination (OR = 2.62, 95% CI: 1.35-5.09), employment status (OR = 2.22, 95% CI: 1.08-4.59), and self-efficacy (OR = 1.09, 95% CI: 1.01-1.19) were the influencing factors in the Pap test experience group. To improve the Pap test screening rate among South Korean women aged 20 to 39, reinforcement strategies and intervention programs that involve age-specific approaches must be established.

Expression of miR-223-3p in patients with hepatitis B virus liver fibrosis and its effect on hepatic stellate cells: An observational study.
To analyze miR-223-3p expression in patients with hepatitis B virus (HBV) live fibrosis and its effects on proliferation, activation, and apoptosis of human hepatic stellate cell line. One hundred patients with HBV-associated liver fibrosis were divided into S0 to 1, S2 to 3, and S4 groups according to Scheuer histological staging; healthy individuals during the same period were enrolled as healthy group. Relative expressions of miR-223-3p in healthy, S0 to 1, S2 to 3, and S4 groups were 0.56 ± 0.11, 1.08 ± 0.27, 2.16 ± 0.42, and 3.59 ± 1.06, respectively. ⋯ Protein expressions of α-smooth muscle actin, transforming growth factor-β1, collagen I, collagen III, p-Smad3, p-Smad2, and B-cell lymphoma 2 were higher in miR-223-3p-mimic group than in CG and NC-mimic groups and lower in miR-223-3p-inhibitor group than in CG and NC-inhibitor group, whereas those of B-cell lymphoma 2-associated death promoter, B-cell lymphoma 2 associated X protein, cleaved caspase3, cleaved caspase9, poly ADP-ribose polymerase were lower in miR-223-3p-mimic group than in CG and NC-mimic group and higher in miR-223-3p-inhibitor group than in CG and NC-inhibitor group (P < .05). HBV liver fibrosis patients had elevated expression of miR-223-3p in plasma. Upregulation of miR-223-3p expression may be related to transforming growth factor-β1/Smad signaling pathway activation.

This study used a conceptual model to examine the factors influencing physical, mental, and overall health-related quality of life (HRQoL) in women and men aged 45 and older with knee osteoarthritis (KOA) in Saudi Arabia. In this multicenter cross-sectional study, we randomly included 356 individuals aged 45 years or above with doctor-confirmed KOA from the orthopedic and physiotherapy departments of the 5 tertiary hospitals in Riyadh, Saudi Arabia, between March 2016 and March 2017. We split all participants into men (n = 146) and women (n = 210) based on gender. ⋯ Women and men aged between 60 and 64 years were more strongly associated significantly with less physical composite scale score by -3.17, (standard error [SE] = 1.71, P = .021) and -3.18 (SE = 1.69, P = .023) respectively, followed by the primary school or less education by -3.40 (SE = 1.27, P = .0002), severe KOA of -8.94 (SE = 0.99, P < .001), eating on the floor bending the knee of -3.93 (SE = 1.63, P = .042), and pain of -2.39 (SE = 0.26, P < .0001). Women and men with primary school or less education significantly had low mental composite scale and 36-item short form health survey scores of -3.07 (SE = 1.22, P = .041) and -3.23 (SE = 0.99, P = .018), respectively, followed by severe KOA of -4.07 (SE = 1.22, P = .001) and -6.50 (SE = 0.83, P < .0001) and eating on the floor, extending the knee at -3.35 (SE = 1.74, P = .043). Risk factors like age, education, pain, body mass index, and severe KOA are linked to poor physical, mental, and overall HRQoL among women and men in Saudi Arabia.
