variable selection is critical to select characteristic variables of critical quality attributes to improve model performance and interpret the identified variables in multivariate calibration. However, classical variable selection methods were developed and optimized by the prediction error. It is rare for the robustness evaluation of variable selection methods. In this study, the robustness of four different variable selection methods was investigated by adding different types of simulate noises to validation set and calibration and validation sets, respectively. The reproducibility as well as root mean squared error of prediction (RMSEP) were used together as common measure in assessing the robustness of different variable selection methods. The robustness of four variable selection methods method was investigated using two near infrared (NIR) datasets including open-source dataset of corn and Chinese herbal medicine (CHM) dataset. The result illustrated that variable importance in projection (VIP) was substantially more robust to additive noise, with smaller RMSEP value and high reproducibility. This provides a novel strategy for the reliability evaluation of variable selection methods in NIR model of critical quality attributes.
To describe the efficacy of infigratinib, a potent, selective fibroblast growth factor receptor (FGFR) 1-3 tyrosine kinase inhibitor, across lines of therapy (LOT) in patients with metastatic urothelial cancer (mUC).

Eligible patients had mUC and prior platinum-based chemotherapy, unless contraindicated, and activating FGFR3 mutation/fusion. Patients received infigratinib 125 mg orally daily (3 weeks on/1 week off) in a single-arm, open-label study. Primary endpoint investigator-assessed confirmed objective response rate (ORR). Disease control rate (DCR), progression-free survival (PFS), best overall response (BOR) that included unconfirmed responses, and overall survival (OS) were also assessed. Subgroup analysis of efficacy and safety outcomes by LOT was performed.

Sixty-seven patients were enrolled; 13 (19.4%) received infigratinib as early-line therapy for mUC due to ineligibility to receive platinum-based chemotherapy. Overall, ORR was 25.4% (95% CI 15.5-37.5) and DCR was 64.2% (95% CI 51.5-75.5). s in mUC.
Combined resection of the right hepatic artery (RHA) is sometimes required to achieve complete resection of hilar cholangiocarcinoma. The present study aimed to evaluate the feasibility of combined resection and subsequent reconstruction by continuous suture of the RHA during left hepatectomy for cholangiocarcinoma.

We retrospectively compared the outcomes after left hepatectomy with biliary reconstruction for cholangiocarcinoma between patients with and without RHA resection and reconstruction.

Of the 25 patients who underwent left hepatectomy combined with biliary reconstruction, eight patients (32%) underwent combined resection and reconstruction of the RHA (AR group). The demographic characteristics were not different between the AR and non-AR groups. The amount of intraoperative bleeding was significantly greater in patients with AR (2350mL vs. 900mL, p=0.017). The prevalence of early complications above grade III in Clavien-Dindo classification and late complications were not significantly different between the AR and non-AR groups. In the AR group, complications directly associated with AR, such as thrombosis or reanastomosis, were not observed. On Kaplan-Meier analysis, recurrence-free survival (p=0.618) and overall survival (p=0.803) were comparable between the two groups despite the advanced T stages in the AR group.

Combined resection and subsequent reconstruction of the RHA during left-sided hepatectomy is a feasible treatment alternative for cholangiocarcinoma.

While more than half of these patients can be cured with modern chemoimmunotherapy regimens, the outcomes of relapsed or refractory disease continue to be very poor. Despite significant developments in targeted cancer therapies and immuno-oncology, the attainability of a cure remained an elusive goal outside of incorporating high doses of chemotherapy followed by hematopoietic stem cell transplantation, for patients who have chemosensitive disease. The development of chimeric antigen receptor T-cell therapy changed that paradigm and introduced a new field of therapeutic possibilities for these patients. In this review, we will discuss the current state of this therapeutic modality in B-cell lymphomas and provide opinions on where future efforts need to focus in order to further improve their clinical utility.
Cystic fibrosis (CF) is a recessive condition caused by variants in each CF transmembrane conductance regulator (CFTR) allele. Clinically affected individuals without two identified causal variants typically have no further interrogation of CFTR beyond examination of coding regions, but the development of variant-specific CFTR-targeted treatments necessitates complete understanding of CFTR genotype.

Whole genome sequences were analyzed on 5,058 individuals with CF. We focused on the full CFTR gene sequence and identified disease-causing variants in three phases screening for known and structural variants; discovery of novel loss-of-function variants; and investigation of remaining variants.

All variants identified in the first two phases and coding region variants found in the third phase were interpreted according to CFTR2 or ACMG criteria (n=371; 16 [4.3%] previously unreported). Full gene sequencing enabled delineation of 18 structural variants (large insertions or deletions), of which two were novel. selleck screening library Additional CFTR variants of uncertain effect were found in 76 F508del homozygotes and in 21 individuals with other combinations of CF-causing variants. Both causative variants were identified in 98.1% (n=4,960) of subjects, an increase of 2.3 percentage points from the 95.8% (n=4,847) who had a registry- or chart-reported disease-causing CFTR genotype. Of the remaining 98 individuals, 78 carried one variant that has been associated with CF (CF-causing [n=70] or resulting in varying clinical consequences n=8]).

Complete CFTR gene sequencing in 5,058 individuals with CF identified at least one DNA variant in 99.6% of the cohort that is targetable by current molecular or emerging gene-based therapeutic technologies.

Many cancers are caused by overweight; however, cancer risk varies among individuals with obesity. Few studies are addressing the relationship between metabolic obesity phenotypes and cancer. This study investigates the association between metabolically healthy overweight (MHOW) or metabolically healthy obesity (MHO) and cancer incidence.

In a nationwide, representative community-based prospective cohort study, 5734 Taiwanese adults were classified into eight phenotypes according to body mass index (underweight <18.5; normal weight 18.5-23.9; overweight 24-26.9; and obese ≥27 kg/m
) and metabolic status (healthy/unhealthy). Participants with healthy cardiometabolic blood profiles included in the metabolic syndrome criteria and an absence of hypertension, diabetes, and hyperlipidemia were considered metabolically healthy. We used the Cox proportional hazards models to estimate the adjusted hazard ratio (HR) and 95% confidence intervals (95% CI).

During 73,389 person-years of follow-up, 428 incident cancers were identified. Compared to the participants with metabolically healthy normal weight, participants with MHOW (adjusted HR 1.39, 95% CI, 0.90-2.13) or MHO (adjusted HR 1.07, 95% CI, 0.51-2.22) had a tendency toward a higher risk of cancer. These associations were stronger in MHOW (adjusted HR 1.77, 95% CI, 1.09-2.86) or MHO (adjusted HR 1.39, 95% CI, 0.66-2.93) participants younger than 65 years.

This study was the first to investigate the impact of metabolic obesity phenotype on the incidence of cancer in the Taiwanese population. Even in the absence of metabolic abnormalities, overweight, and obesity may cause a modest increase in the risk of developing cancer.

Greater visceral fat area (VFA) is associated with cardiometabolic outcomes. We sought to identify cross-sectional and longitudinal associations between amino acid (AA) levels and VFA in Japanese-Americans.

From the cohort of 342 Japanese-American participants (51% men) in a study of diabetes risk factors who were free from diabetes, we measured levels of 20 AA by mass spectrometry, height, weight, waist circumference (WC), VFA, subcutaneous fat area by single-slice CT at the umbilicus. Using AA significantly associated with VFA in univariate analyses, we created a VFA prediction index, termed the 4A index. We compared area under receiver-operating characteristic curve (AUROC) of the 4A index to WC and an existing AA index (Yamakado et al. Clin Obes 2012) in classifying VFA at different cutoff values. We fit age-adjusted linear regression models to evaluate associations between AA levels and change in VFA over 5 years.

All 20 AA levels significantly detected VFA excess, but WC was better. The 4A index performed better than Yamakado index at classifying VFA ≥ 100 cm
(0.798, 0.807 vs. 0.677, 0.671 for men and women, p < 0.0033) and VFA ≥ sex-specific median values (0.797, 0.786 vs. 0.676, 0.629 for men and women, p < 0.0017). AA significantly associated with change in VFA over 5 years were asparagine, glutamate, glutamine, glycine, methionine, proline, threonine in men; and histidine, isoleucine, tyrosine in women (p < 0.05).

The 4A index can serve as a biomarker for VFA in Japanese-Americans and be considered for this purpose when WC is not available.

Systematic review and meta-analysis conducted to investigate the effect of stratified pre-pregnancy maternal body mass index on twenty maternal and fetal/neonatal adverse outcomes.

PubMed, Google Scholar, Medline, Embase, Web of Science databases were searched from inception till July 11, 2020. Cohort studies were included. The pooled odds ratio with 95% confidence interval was reported considering the random effect and the quality effect model. The sub-group analysis and meta-regression were conducted for BMI cut-offs, geographical region, source of BMI, and sample size.

Overall, 86 studies representing 20,328,777 pregnant women were included in this meta-analysis. Our study reveals that overweight and obese mothers are at increased odds of cesarean delivery, elective cesarean delivery, emergency cesarean delivery, gestational diabetes, gestational hypertension, induction of labor, postpartum hemorrhage, pre-eclampsia, pre-term premature rupture of membrane, and the fetuses/neonates of overweight and obese mothers are at increased risk of admission in the newborn intensive care unit, APGAR scores less than 7 at 5 min, large for gestational age, macrosomia, extreme pre-term birth in pregnant mothers compared with standard BMI mothers.
