Chemotherapy-induced nausea and vomiting (CINV) can lead to a significant deterioration in the quality of life of cancer patients receiving chemotherapy. This study aimed to determine whether ABCB1 2677G > T/A was associated with complete response (CR; defined as no vomiting and no rescue medication) in acute phase (CR
, as well as to explore the genetic factors affecting delayed phase (CR
) CINV in cancer patients treated with a standard triple antiemetic regimen that included aprepitant.
This prospective single-center study included a total of 166 chemotherapy-naïve patients with breast cancer who received a standard dose of doxorubicin and cyclophosphamide combination chemotherapy; granisetron, dexamethasone, and aprepitant were administered prior to chemotherapy. CR
was compared between minor allele homozygous (TT, AA, and TA) and major allele homozygous plus heterozygous (GG, GA, and GT) groups of ABCB1 2677G > T/A. In addition, 14 genetic polymorphisms were genotyped and their associations with CRs were investigated.
The proportion of patients who achieved CR
, which was the primary endpoint of this study, was 59% in the minor allele homozygous and 61% in the major allele homozygous plus heterozygous groups of ABCB1 2677G > T/A. #link# Although this difference was not statistically significant, multivariate logistic regression analysis adjusted for potential risk factors showed that TACR1 1323TT (OR, 2.57; P = 0.014) was a significant determinant of CR
.
No significant association was found between ABCB1 2677G > T/A and CR
. However, it was observed that the polymorphism of TACR1, which encodes the neurokinin 1 receptor, might be a potential genetic risk factor for the development of delayed phase CINV.

However, its effectiveness for multiplexed quantitation by traditional tandem mass spectrometry (MS2) suffers from ratio distortion. Synchronous precursor selection (SPS) MS3 has been widely accepted for improved quantitation accuracy, but concurrently decreased proteome coverage. Recently, Reparixin -Time Search algorithm has been integrated with the SPS MS3 pipeline (RTS MS3) to provide accurate quantitation and improved depth of coverage. In this mechanistic study of the impact of exposure to hydrogen sulfide (H2S) on the respiration of swine, we used TMT-based comparative proteomics of lung tissues from control and H2S-treated subjects as a test case to evaluate traditional MS2, SPS MS3, and RTS MS3 acquisition methods on both the Orbitrap Fusion and Orbitrap Eclipse platforms. Comparison of the results obtained by the MS2 with those of SPS MS3 and RTS MS3 methods suggests that the MS3-driven quantitative strategies provided a more accurate global-scale quantitation; however, only RTS MS3 provided proteomic coverage that rivaled that of traditional MS2 analysis. RTS MS3 not only yields more productive MS3 spectra than SPS MS3 but also appears to focus the analysis more effectively on unique peptides. Furthermore, pathway enrichment analyses of the H2S-altered proteins demonstrated that an additional apoptosis pathway was discovered exclusively by RTS MS3. This finding was verified by RT-qPCR, western blotting, and TUNEL staining experiments. We conclude that RTS MS3 workflow enables simultaneous improvement of quantitative accuracy and proteome coverage over alternative approaches (MS2 and SPS MS3). Graphical abstract.
The aims of this systematic review and meta-analysis are to provide a summary of the current literature concerning compulsory treatments in patients with eating disorders (ED) and to understand whether compulsorily and involuntarily treated patients differ in terms of baseline characteristics and treatment outcomes.
Relevant articles were identified following the PRISMA guidelines by searching the following terms "treatment refusal", "forced feeding", "compulsory/coercive/involuntary/forced treatment/admission", "eating disorders", "feeding and eating disorders", "anorexia nervosa", "bulimia nervosa". Research was restricted to articles concerning humans and published between 1975 and 2020 in English.
Out of 905 articles retrieved, nine were included for the analyses allowing the comparisons between 242 compulsorily and 738 voluntarily treated patients. Mean body mass index (BMI) was slightly lower in patients compelled to treatments. Mean illness duration, BMI at discharge and BMI variation showed no significant differences between the two groups. Average length of hospitalization was 3weeks longer among compulsory-treated patients, but this did not result in a higher increase in BMI. No significant risk difference on mortality was estimated (three studies).
Compulsory treatments are usually intended for patients having worse baseline conditions than voluntary ones. Those patients are unlikely to engage in treatments without being compelled but, after the treatments, albeit with longer hospitalisations, they do achieve similar outcomes. Therefore, we can conclude that forcing patients to treatment is a conceivable option.

Although chest pain and acute coronary syndrome (ACS) are among the most common complaints in the Emergency Departments (ED), little is known about this topic in the octogenarian population.
This study aimed to describe the clinical presentation and to evaluate survival time according to the ACS type in a group of 80-year-old or over patients admitted for chest pain to an ED.
Patients were classified according to the discharge diagnosis. A multivariable Cox regression analysis was done to assess the association between ACS type and mortality with the non-ACS chest pain group as the reference category.
ACS was diagnosed in 170 of the 391 patients analyzed and 51% of ACS patients were female. Within the ACS patients, 18.8% presented STEMI, 57% NSTEMI, and 24% unstable angina (UA). Most of the patients were treated conservatively. In the adjusted analysis, the incidence of death at 40months of follow-up was higher in patients with STEMI (HR 3.24; CI 1.59-6.56) than NSTEMI (HR 2.53; CI 1.56-4.11). There was no difference between patients with UA and the non-ACS group (HR 0.
