Objective Pancreatic cancer (PC) is a serious disease with poor outcomes, and its prevalence has been increasing steadily. The circadian rhythm (CR) is involved in multiple physiological events and maintains homeostasis. Alterations in the CR elevate the risk of developing cancer. The present case-control research was carried out to estimate the possible association between PERIOD2/PERIOD3 (PER2/PER3) gene variable number tandem repeat polymorphism (VNTR) variants and PC in the Turkish population. Materials and Methods A total of 198 subjects (78 patients with PC and 120 healthy controls) were enrolled in this work. Genomic DNA was collected from peripheral blood mononuclear cells, and genotypic analyses was performed using a polymerase chain reaction (PCR) method. Odds ratio (OR) with a 95% confidence interval (95% CI) was calculated using the χ2 test. Results The frequency of the 4R (4 repeats)/3R (3 repeats), 3R/3R genotypes, and 3R allele of PER2 VNTR in patients with PC was significantly higher than in the control group (p = 0003, p = 0.00004, respectively). PER2 VNTR 4/5 genotype was related to perineural invasion (p = 0.040). The genotype and allele distribution of PER3 VNTR variant did not show any statistical difference between the two groups (p > 0.05). The PER2/PER3 VNTR 4/5-4R/3R combined genotype was increased in the patient group (p = 0.013), while 4/5-4R/4R combined genotype was increased in the control group (p = 0.0001). Conclusions Our work has indicated that PER2 VNTR 3R allele may play a crucial role in the pathogenesis of PC in Turkish patients, which may become a useful marker for predicting the development of PC. Furthermore, the PER2 VNTR genotype seems to be related to perineural invasion in PC.We investigated the efficacy and safety profiles of 4-weekly docetaxel for castration-resistant prostate cancer. Patients treated with ≥2 courses of docetaxel chemotherapy (median, 70 mg/m2) between 2008 and 2018 were included. Among 125 Japanese men, 40 (32.0%) and 85 (68.0%) were treated with 3-weekly and 4-weekly regimens, respectively. In the 4-weekly regimen, the risks of progression, treatment failure, and any-cause mortality were comparable to those in the 3-weekly regimen. Galardin The incidences of severe adverse events were also similar between the 3-weekly and 4-weekly regimens. These data suggest that the 4-weekly regimen may be an acceptable option for selected patients.The computation of genomic distances has been a very active field of computational comparative genomics over the past 25 years. Substantial results include the polynomial-time computability of the inversion distance by Hannenhalli and Pevzner in 1995 and the introduction of the double cut and join distance by Yancopoulos et al. in 2005. Both results, however, rely on the assumption that the genomes under comparison contain the same set of unique markers (syntenic genomic regions, sometimes also referred to as genes). In 2015, Shao et al. relax this condition by allowing for duplicate markers in the analysis. This generalized version of the genomic distance problem is NP-hard, and they give an integer linear programming (ILP) solution that is efficient enough to be applied to real-world datasets. A restriction of their approach is that it can be applied only to balanced genomes that have equal numbers of duplicates of any marker. Therefore, it still needs a delicate preprocessing of the input data in which excessive copies of unbalanced markers have to be removed. In this article, we present an algorithm solving the genomic distance problem for natural genomes, in which any marker may occur an arbitrary number of times. Our method is based on a new graph data structure, the multi-relational diagram, that allows an elegant extension of the ILP by Shao et al. to count runs of markers that are under- or over-represented in one genome with respect to the other and need to be inserted or deleted, respectively. With this extension, previous restrictions on the genome configurations are lifted, for the first time enabling an uncompromising rearrangement analysis. Any marker sequence can directly be used for the distance calculation. The evaluation of our approach shows that it can be used to analyze genomes with up to a few 10,000 markers, which we demonstrate on simulated and real data.Neuromedin U (NMU) is a neuropeptide involved in gut-brain axis, energy balance and immune response. We aimed at analysing the association between NMU epigenetic variability and metabolic indices and the potential mediating role of low-grade inflammation in a general population of Italian adults.NMU Blood DNA methylation levels at two CpG islands (NMU76 and NMU32) were analysed using pyrosequencing in a randomly selected sub-cohort of 1,160 subjects from the Moli-sani study (≥35years; 49.20% men). Multivariable regressions adjusted for age, sex, smoking, alcohol and vegetable consumption were performed to estimate the associations between methylation and metabolic phenotypes (BMI, waist-to-hip ratio, blood pressure, glucose, HOMA-IR, lipids, lipoprotein(a) and apolipoproteins). Mediation analysis was performed to identify the influence of low-grade inflammation in the association using a composite index based on C reactive protein, granulocyte-to-lymphocyte ratio (GLR), platelet and white blood cell counts (INFLA-score).Using principal component analysis four methylation factors were identified NMU76-F1, NMU76-F2, NMU32-F1 and NMU32-F2. NMU76-F1 was FDR significantly associated with total cholesterol (for 1 SD increase β = 4.5 ± 1.4 mg/dL of, R2 = 10.8%, p = 0.001), ApoB (0.03 ± 0.01 g/L, 12.2%, p = 0.0004), with INFLA-score (1.05 ± 0.22, p = 2.7E-6) and GLR (-0.27 ± 0.03, 30.4%, p = 1.3E-20). GLR and lymphocyte numbers mediate the association of NMU76-F1 with cholesterol (24.0% of total effect, Sobel p = 0.013) and ApoB (42.6%, p = 9E-7), respectively.These findings suggest that NMU promoter methylation patterns could mark a pathway linking lipids with haematopoiesis and systemic inflammation.Bariatric surgery is an effective treatment for patients with idiopathic intracranial hypertension (IIH), a condition that is associated with skull base defects. A 55-year-old woman presented with symptoms of intractable nausea and vomiting, followed by headache and confusion two weeks after an elective laparoscopic vertical sleeve gastrectomy procedure. She had a presumed diagnosis of IIH and a remote history of CSF oto/rhinorrhea treated with a lumbar peritoneal (LP) shunt. Computed tomography (CT) scan of the head revealed tension pneumocephalus with midline shift and dehiscence of the tegmen. The patient underwent emergent craniotomy for decompression of the air-filled temporal lobe, clamping of the LP shunt, and repair of the skull base defect. Caution should be exercised in obese patients with a history of CSF leak secondary to a middle fossa skull base defect when being evaluated for bariatric surgery.
