Background: Tamoxifen (TAM) is a frequently used hormonal prodrug for patients with breast cancer that needs to be activated by cytochrome P450 2D6 (CYP2D6) into Zusammen-endoxifen (Z-END). Objective: The purpose of the study was to determine the association between CYP2D6*10 (c.100C>T) genotype and attainment of the plasma steady-state Z-END minimal threshold concentration (MTC) in Indonesian women with breast cancer. Methods: A cross-sectional study was performed in 125 ambulatory patients with breast cancer consuming TAM at 20 mg/day for at least 4 months. The frequency distribution of CYP2D6*10 (c.100C>T) genotypes (C/C: wild type; C/T: heterozygous mutant; T/T: homozygous mutant) was detected using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP), the results of which were subsequently confirmed by sequencing. The genotypes were categorized into plasma Z- END concentrations of <5.9 ng/mL and ≥5.9 ng/mL, which were measured using ultra performance liquid chromatography tandem mass spectrometry (UPLC-MS/MS). Results: Percentages of C/C, CT, and T/T genotypes were 22.4%, 29.6%, and 48.8%, respectively. Median (25-75%) Z-END concentrations in C/C, C/T, and T/T genotypes were 9.58 (0.7-6.0), 9.86 (0.7-26.6), and 3.76 (0.9-26.6) ng/mL, respectively. Statistical analysis showed a significant difference in median Z-END concentration between patients with T/T genotype and those with C/C or C/T genotypes (p<0.001). There was a significant association between CYP2D6*10 (c.100C>T) genotypes and attainment of plasma steady-state Z-END MTC (p<0.001). Conclusion: There was a significant association between CYP2D6*10 (c.100C>T) and attainment of plasma steady-state Z-END MTC in Indonesian breast cancer patients receiving TAM at a dose of 20 mg/day.

The Impact

Abstract Objectives Given the influence of sensory signals on food intake regulation and the subsequent nutritional status, it is important to reduce the impact of commonly observed smell and taste alterations on the pleasure of eating during chemotherapy. This study aimed to examine the effect of various types of flavor enhancement on the appreciation of an appetizer by a group of patients undergoing chemotherapy. Methods Five eggplant appetizers with no seasoning (REF) or enhanced with either salt, lemon, garlic or cumin were developed. In this cross-sectional study, 36 healthy female subjects (age 58 ± 7 y) (control group) and 84 breast cancer patients (age 56 ± 11 y) treated with chemotherapy were recruited. A hierarchical cluster analysis based on patients' self-reported smell and taste abilities classified the patients in two groups: the ‘unaltered, (high sensory abilities) n = 49’ and the ‘altered, (poor sensory abilities), n = 35’ group. Participants tasted and assessed the appreciation of the reference appetizer on a visual analog scale and performed a randomized comparative liking task, by rating the appreciation for each flavor-enhanced appetizer relative to the REF (one-sample t-test). Results There was no significant difference in the appreciation of the REF appetizer between the three groups (P &gt; 0.05). In the comparative liking task, the control group rated similarly the appreciation between the flavor-enhanced and the REF appetizers except for the cumin-enhanced appetizer, which was appreciated significantly more than the REF (P &lt; 0.001). Patients in both ‘altered’ and ‘unaltered’ groups appreciated similarly the cumin appetizer (P &gt; 0.05), more the salt and garlic-enhanced appetizers (P ≤ 0.001, P = 0.005, respectively) and significantly less the lemon-enhanced appetizer relative to the REF (P = 0.029), confirming a tendency for patients to reject acid-flavored foods. Conclusions The salt and garlic enhancements were appreciated by the patients independent of the stage of chemotherapy or the severity of smell and taste alterations. Flavor enhancement seems a good strategy to maintain the pleasure of eating in patients undergoing chemotherapy. Further research is still needed on the appreciation and intake of a complete meal (starter, main course, dessert). Funding Sources APICIL and ELIOR groups.

Abstract Background Sarcocystis species are obligatorily heteroxenous parasites, of which some are zoonotic, representing a public health and economic impact. This study investigated the occurrence of Sarcocystis spp. in cattle sampled from a Belgian slaughterhouse. Methods A total of 200 carcasses were included in the study, sampled during 10 sampling days. The sedimentation method was applied to isolate the sarcocysts from both heart and diaphragm muscles collected from each carcass. Multiplex PCR, PCR–RFLP as well as cox1 gene sequencing techniques were applied serially on collected sarcocysts for species identification. Results Sarcocystis spp. were detected in 64% (128/200; 95% CI 57–71%) of the sampled carcasses. Female dairy cattle presented the highest Sarcocystis occurrence rate (91%) as well as the highest Sarcocystis species diversity compared to female beef and male beef. Sarcocystis spp. were detected more often in the heart muscles than in the diaphragm among female beef (p < 0.001) and dairy carcasses (p = 0.001), while in male carcasses no significant difference was observed (p = 0.763). The effect of age was not significant in male carcasses (p = 0.872), while the odds of finding sarcocysts significantly increased with age (p = 0.003) within both types of female carcasses. S. cruzi was the most prevalent species and was found in 56.5% (113/200) of the carcasses, followed by S. hominis (21.0%, 42/200), S. bovifelis (12.5%, 25/200), S. bovini (2.0%, 4/200), S. hirsuta (1.5%, 3/200) and S. heydorni (0.5%, 1/200). Six different species were detected in the diaphragm, while only two species were recovered from the heart. S. cruzi was the most prevalent species in heart, while in the diaphragm, this was S. hominis. Conclusions The detection of S. hominis in 21% of the sampled carcasses presents a potential food safety issue, and further research is warranted into controlling this infection. Graphic Abstract

AbstractReports on the secular trend of pubertal onset indicate a recent earlier start especially in girls. Bisphenol A (BPA), which posses estrogenic activity, might be a cause of advanced puberty. The objective of the study was to determine the association between BPA and advanced puberty.A cross-sectional study was conducted in patients with advanced puberty (n=41) compared to age-matched controls (n=47). Anthropometric measurements, estradiol, basal and gonadotropin releasing hormone (GnRH)-stimulated follicle stimulating hormone (FSH) and luteinizing hormone (LH) levels, uterine sizes, ovarian diameters and bone ages were obtained. Urinary BPA concentrations were analyzed by ultra-performance liquid chromatography-tandem mass spectrometry (UPLC/MSMS) with the lower limit of quantification (LLOQ) of 0.05 ng/mL.The median adjust-BPA concentration in advanced puberty group was higher than in control groups [1.44 vs. 0.59 μg/g creatinine (Cr): p<0.05]. We also found that the median adjust-BPA concentration in girls with advanced puberty who were overweight/obese, was greater than in the normal pubertal overweight/obese girls (1.74 vs. 0.59 μg/g Cr: p<0.05), and was in the same trend among normal weight girls with advanced and normal puberty (0.83 vs. 0.49 μg/g Cr: p=0.09), but not statistically significant.The present findings suggest that BPA exposure appears to be related to an earlier age at onset of puberty especially in obese girls.

Background Breast cancer survivor goes through a period of needs in their post-treatment daily life. Relatively few studies have been conducted to understand the unmet needs among breast cancer survivors in Bangladesh. Recognize and measure patterns and predictors of unmet needs of breast cancer patients was the aim of the study. Objective To identify and measure patterns and predictors of unmet needs of breast cancer patients in Bangladesh. Method A cross-sectional study among 138 breast cancer patients; conveniently selected from two public and two private cancer institutes. Face-to-face interview for data collection and medical record review for checklist was done. Unmet needs have been determined by the supportive care needs survey short form 34 scale. Logistic regression analyses were performed to identify the predictors of unmet needs. Results The study indicated the top 10 moderate-to-high needs; among which the top five needs were from the information need domain. Surprisingly, private cancer treatment centers were identified as a significant predictor for unmet needs. Patients from private cancer institutes reported more explanation needs as well as needs with their physical and daily living and sexuality. Furthermore, the type of treatment like patient receiving combine treatment therapy reported more need for help compared to the patient receiving chemotherapy alone. Moreover, housewives reported the low need for patient care and support systems as a result of their reluctant behavior towards their health. Conclusion Individual’s unmet need assessment should be a part of every treatment protocol of breast cancer for a better treatment outcome.
