Objective: We examined the relationships between tumor tissue calcifications of papillary thyroid cancer (PTC), body mass index (BMI), and tumor invasiveness. Methods: This was a retrospective analysis of 13,995 patients with PTC. Comparisons were made between the clinical and pathologic features of the tumor tissue calcifications group and non–tumor tissue calcifications group. Odds ratios (ORs) of tumor tissue calcifications, BMI, and tumor invasiveness features were calculated using a binary logistic regression model. We analyzed the relationship between tumor tissue calcifications and certain characteristics of thyroid cancer based on the pathologic findings. Results: BMI was positively correlated with tumor tissue calcifications in patients with PTC (OR, 1.015; P = .011), and obesity increased the risk of tumor tissue calcifications (OR, 1.374; P = .038). Calcifications were positively correlated with T-size (OR, 1.899; P<.001), multifocality (OR, 1.217; P<.001), extrathyroidal extension (ETE) (OR, 1.287; P<.001), high T-stage (OR, 1.765; P<.001), N+ (OR, 1.763; P<.001), and a higher number of lymph node metastases (OR, 1.985; P<.001). Compared with normal-weight patients with tumor tissue calcifications, obese patients with tumor tissue calcifications had an increased risk of ETE (ORobesity, 1.765 vs. ORnormal, 1.300) and N+ (ORobesity, 1.992 vs. ORnormal, 1.784). Conclusion: Tumor tissue calcifications are positively correlated with the invasiveness of PTC. Obesity further promotes the risk of tumor invasiveness in PTC combined with tumor tissue calcifications. These findings suggest that more comprehensive evaluations by trained pathologists may help physicians identify the optimal therapeutic regimens in the postoperative period.

The aim of this study was to evaluate steroid receptors’ status of tumor tissue in different molecular biological types of endometrial cancer (EC), subdivided according to the current classification, and their colonization by lymphocytic and macrophage cells, taking into account body mass index of the patients. Materials and methods: Material from treatment-naive patients with EC (total n = 229) was included; the number of sick persons varied depending on the method used. The average age of patients was close to 60 years, and about 90% of them were postmenopausal. It was possible to divide the results of the work into two main subgroups: a) depending on the molecular biological type of the tumor (determined on the basis of genetic and immunohistochemical analysis), and b) depending on the value of the body mass index (BMI). The latter approach was used in patients with EC type demonstrating a defective mismatch repair of the incorrectly paired nucleotides (MMR-D) and with a type without characteristic molecular profile signs (WCMP), but was not applied (due to the smaller number of patients) in EC types with a POLE gene mutation or with expression of the oncoprotein p53. According to the data obtained, when comparing various types of EC, the lowest values of Allred ER and PR scores were revealed for POLE-mutant and p53 types, while the “triple-negative” variant of the tumor (ER-, PR-, HER2/neu-) was most common in POLE-mutant (45.5% of cases) and WCMP (19.4%) types of EC. The p53+ type of EC is characterized by inclination to the higher expression of the macrophage marker CD68 and lymphocytic Foxp3, as well as mRNA of PD-1 and SALL4. In addition to the said above, for WCMP type of EC is peculiar, on the contrary, a decrease in the expression of lymphocytic markers CD8 (protein) and PD-L1 (mRNA). When assessing the role of BMI, its value of >30.0 (characteristic for obesity) was combined with an inclination to the increase of HER-2/neu expression in the case of MMR-D EC type and to the decrease of HER-2 /neu, FOXp3 and ER expression in WCMP type. Conclusions: The accumulated information (mainly describing here hormonal sensitivity of the tumor tissue and its lymphocytic-macrophage infiltration) additionally confirms our earlier expressed opinion that the differences between women with EC are determined by both the affiliation of the neoplasm to one or another molecular biological type (subdivided according to the contemporary classification), as well as by body mass value and (very likely) the associated hormonal and metabolic attributes.

The Impact

Abstract Background Although obesity is a well-recognised risk factor for cardiovascular disease (CVD), the impact of long-term body mass index (BMI) changes in overweight or obese adults, on the risk of heart failure, CVD and mortality has not been quantified. Methods This population-based cohort study used routine UK primary care electronic health data linked to secondary care and death-registry records. We identified adults who were overweight or obese, free from CVD and who had repeated BMI measures. Using group-based trajectory modelling, we examined the BMI trajectories of these individuals and then determined incidence rates of CVD, heart failure and mortality associated with the different trajectories. Cox-proportional hazards regression determined hazards ratios for incident outcomes. Results 264,230 individuals (mean age 49.5 years (SD 12.7) and mean BMI 33.8 kg/m2 (SD 6.1)) were followed-up for a median duration of 10.9 years. Four BMI trajectories were identified, corresponding at baseline, with World Health Organisation BMI classifications for overweight, class-1, class-2 and class-3 obesity respectively. In all four groups, there was a small, stable upwards trajectory in BMI (mean BMI increase of 1.06 kg/m2 (± 3.8)). Compared with overweight individuals, class-3 obese individuals had hazards ratios (HR) of 3.26 (95% CI 2.98–3.57) for heart failure, HR of 2.72 (2.58–2.87) for all-cause mortality and HR of 3.31 (2.84–3.86) for CVD-related mortality, after adjusting for baseline demographic and cardiovascular risk factors. Conclusion The majority of adults who are overweight or obese retain their degree of overweight or obesity over the long term. Individuals with stable severe obesity experience the worst heart failure, CVD and mortality outcomes. These findings highlight the high cardiovascular toll exacted by continuing failure to tackle obesity.

The Impact

Abstract Background Total knee arthroplasty is known to successfully alleviate pain and improve function in endstage knee osteoarthritis. However, there is some controversy with regard to the influence of obesity on clinical benefits after TKA. The aim of this study was to investigate the impact of body mass index (BMI) on improvement in pain, function and general health status following total knee arthroplasty (TKA). Methods A single-centre retrospective analysis of primary TKAs performed between 2006 and 2016 was performed. Data were collected preoperatively and 12-month postoperatively using WOMAC score and EQ-5D. Longitudinal score change was compared across the BMI categories identified by the World Health Organization. Results Data from 1565 patients [mean age 69.1, 62.2% women] were accessed. Weight distribution was: 21.2% BMI < 25.0 kg/m2, 36.9% BMI 25.0–29.9 kg/m2, 27.0% BMI 30.0–34.9 kg/m2, 10.2% BMI 35.0–39.9 kg/m2, and 4.6% BMI ≥ 40.0 kg/m2. All outcome measures improved between preoperative and 12-month follow-up (p < 0.001). In pairwise comparisons against normal weight patients, patients with class I-II obesity showed larger improvement on the WOMAC function and total score. For WOMAC pain improvements were larger for all three obesity classes. Conclusions Post-operative improvement in joint-specific outcomes was larger in obese patients compared to normal weight patients. These findings suggest that obese patients may have the greatest benefits from TKA with regard to function and pain relief one year post-op. Well balanced treatment decisions should fully account for both: Higher benefits in terms of pain relief and function as well as increased potential risks and complications.
