Aims Thresholds for operative eligibility based on body mass index (BMI) alone may restrict patient access to the benefits of arthroplasty. The purpose of this study was to evaluate the relationship between BMI and improvements in patient-reported outcome measures (PROMs), and to determine how many patients would have been denied improvements in PROMs if BMI cut-offs were to be implemented. Methods A prospective cohort of 3,449 primary total hip arthroplasties (THAs) performed between 2015 and 2018 were analyzed. The following one-year PROMs were evaluated: hip injury and osteoarthritis outcome score (HOOS) pain, HOOS Physical Function Shortform (PS), University of California, Los Angeles (UCLA) activity, Veterans Rand-12 Physical Component Score (VR-12 PCS), and VR-12 Mental Component Score (VR-12 MCS). Positive predictive values for failure to improve and the number of patients denied surgery in order to avoid a failed improvement were calculated for each PROM at different BMI cut-offs. Results There was a trend to improved outcomes in terms of pain and function improvements with higher BMI. Patients with BMI ≥ 40 kg/m2 had median (Q1, Q3) HOOS pain improvements of 58 points (interquartile range (IQR) 41 to 70) and those with BMI 35 to 40 kg/m2 had median improvements of 55 (IQR 40 to 68). With a BMI cut-off of 30 kg/m2, 21 patients would have been denied a meaningful improvement in HOOS pain score in order to avoid one failed improvement. At a 35 kg/m2 cut-off, 18 patients would be denied improvement, at a 40 kg/m2 cut-off 21 patients would be denied improvement, and at a 45 kg/m2 cut-off 21 patients would be denied improvement. Similar findings were observed for HOOS-PS, UCLA, and VR-12 scores. Conclusion Patients with higher BMIs show greater improvements in PROMs. Using BMI alone to determine eligibility criteria did not improve the rate of clinically meaningful improvements. BMI thresholds prevent patients who may benefit the most from surgery from undergoing THA. Surgeons should consider PROMs improvements in determining eligibility for THA while balancing traditional metrics of preoperative risk stratification.

OBJECTIVEDischarge to an inpatient rehabilitation facility or another acute-care facility not only constitutes a postoperative challenge for patients and their care team but also contributes significantly to healthcare costs. In this era of changing dynamics of healthcare payment models in which cost overruns are being increasingly shifted to surgeons and hospitals, it is important to better understand outcomes such as discharge disposition. In the current article, the authors sought to develop a predictive model for factors associated with nonroutine discharge after surgery for grade I spondylolisthesis.METHODSThe authors queried the Quality Outcomes Database for patients with grade I lumbar degenerative spondylolisthesis who underwent a surgical intervention between July 2014 and June 2016. Only those patients enrolled in a multisite study investigating the impact of fusion on clinical and patient-reported outcomes among patients with grade I spondylolisthesis were evaluated. Nonroutine discharge was defined as those who were discharged to a postacute or nonacute-care setting in the same hospital or transferred to another acute-care facility.RESULTSOf the 608 patients eligible for inclusion, 9.4% (n = 57) had a nonroutine discharge (8.7%, n = 53 discharged to inpatient postacute or nonacute care in the same hospital and 0.7%, n = 4 transferred to another acute-care facility). Compared to patients who were discharged to home, patients who had a nonroutine discharge were more likely to have diabetes (26.3%, n = 15 vs 15.7%, n = 86, p = 0.039); impaired ambulation (26.3%, n = 15 vs 10.2%, n = 56, p < 0.001); higher Oswestry Disability Index at baseline (51 [IQR 42–62.12] vs 46 [IQR 34.4–58], p = 0.014); lower EuroQol-5D scores (0.437 [IQR 0.308–0.708] vs 0.597 [IQR 0.358–0.708], p = 0.010); higher American Society of Anesthesiologists score (3 or 4: 63.2%, n = 36 vs 36.7%, n = 201, p = 0.002); and longer length of stay (4 days [IQR 3–5] vs 2 days [IQR 1–3], p < 0.001); and were more likely to suffer a complication (14%, n = 8 vs 5.6%, n = 31, p = 0.014). On multivariable logistic regression, factors found to be independently associated with higher odds of nonroutine discharge included older age (interquartile OR 9.14, 95% CI 3.79–22.1, p < 0.001), higher body mass index (interquartile OR 2.04, 95% CI 1.31–3.25, p < 0.001), presence of depression (OR 4.28, 95% CI 1.96–9.35, p < 0.001), fusion surgery compared with decompression alone (OR 1.3, 95% CI 1.1–1.6, p < 0.001), and any complication (OR 3.9, 95% CI 1.4–10.9, p < 0.001).CONCLUSIONSIn this multisite study of a defined cohort of patients undergoing surgery for grade I spondylolisthesis, factors associated with higher odds of nonroutine discharge included older age, higher body mass index, presence of depression, and occurrence of any complication.

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.

Objective: Obesity has recently been recognized as a chronic low-grade inflammation condition. We aimed to compare the predictive values of insulin resistance and inflammatory indices in individuals with obesity. Materials and Methods: 124 people who had a health check for obesity-related risk factors in our hospital between June 2018 and September 2019 were included in the study. Inflammatory markers of the patients were evaluated. Results: The study group consists of a total of 224 people, and we compared the demographic data and laboratory parameters of the individuals. C-reactive protein (CRP) levels of obese individuals were statistically higher than those with normal body mass index (p <0.001). There was no statistically significant difference between the groups in terms of neutrophil-lymphocyte ratio (NLR) and platelet-lymphocyte ratio (PLR) values, among other inflammation markers. A positive and statistically significant correlation was found between body mass index and CRP level (r = 0.334, p <0.001). There was no significant correlation between body mass index and NLR and PLR. Conclusion: As a result, CRP levels of obese individuals were statistically higher than individuals with normal body mass index. No statistically significant difference was found between the groups in terms of NLR and PLR values among other inflammation markers.

Introduction. The most frequent clinical outcomes in sarcoidosis patients are typically focused on the objective measurements of functions of the involved organs, but, generally, they do not take into account the individual perception of patients? everyday functioning. The aim of this study was to determine the type of association between the subjective disease outcomes and other objective conventional parameters in patients with sarcoidosis. Material and Methods. In the cross-sectional study including 172 sarcoidosis patients (122 females), quality of life was measured by a generic instrument, i.e. fifteen-dimensional measure of health-related quality of life together with a respiratory specific instrument, i.e. St George?s Respiratory Questionnaire; symptoms of fatigue were measured by Fatigue Scale and dyspnea was measured by the Basal Dyspnea Index. Body-mass index and the course of the disease (acute vs. chronic) were also evaluated. Pulmonary function was assessed by spirometry. Results. Acute sarcoidosis was present in 48 (28%) patients. Mean body mass index was 27.01?5.2. Only 20 (12%) patients had lower forced expiratory volume in one second values (<80%) that indicated the existance of obstructive ventilatory impairment. Multivariate linear regression analysis revealed that body mass index, clinical course of disease and spirometric parameter forced expiratory volume in one second were the significant predictors (R2=0.929, p<0.01) of sarcoidosis related fatigue (B=0.061, B=0.406, B=0.452; respectively). Body mass index and forced expiratory volume in one second were the only parameters that significantly predicted both patients? quality of life (R2=0.932; B=0.017, B=0.263) and dyspnea (R2=0.847; B=0.025, B=0.668). Conclusions. It is important to measure both subjective patient-reported outcomes and objective disease parameters in sarcoidosis since they represent different aspects of the disease. All applied measuring instruments for the examined subjective outcomes demonstrated good measuring properties.

Introduction The aetiology of coccydynia can be multifactorial, with several associated factors such as obesity, female gender and low mood. The long-term results of operative interventions, such as manipulation under anaesthesia and coccygectomy are variable, ranging from 63–90%. Materials and methods Our aim was to identify whether age, trauma and body mass index (BMI) were independent prognostic factors in coccydynia treatment. All patients who presented to the Royal Derby Hospital with a primary diagnosis of coccydynia between January 2011 and January 2015 who had injections, manipulation under anaesthesia or coccygectomy were included. We used patient-reported satisfaction score as the primary outcome measure. We hypothesised that patients with preceding history of trauma and with high BMI (> 25) would be less satisfied. We divided patient BMI into four groups, following World Health Organization guidelines: group A (18.5–24.9), group B (25–29.9), group C (30–39.9) and group D (> 40). Results A total of 748 patients were diagnosed with coccydynia. Of these, 201 patients had 381 injections, 40 had 98 manipulations under anaesthesia and 9 had coccygectomy. Mean age was 46.4 years; 26% of patients had trauma to the coccyx. The mean time to follow-up was 7.3 months. We found a statistically significant difference (P = 0.03) between satisfaction scores in groups B and D. Patients who had trauma improved significantly (P = 0.04). The odds ratio calculation of coccygectomy and BMI revealed a higher risk of coccygectomy in Group A. Discussion This is the first study to establish BMI and trauma as independent prognostic factors for coccydynia treatment. Our hypothesis that patients with higher BMI would have lower satisfaction levels has been proven true.

Abstract Background Obesity is defined as unhealthy excess body fat, which increases the risk of premature mortality from noncommunicable diseases. Early screening and prevention of obesity is critical for averting associated morbidity, disability, and mortality. Ethiopia has been using the international (WHO’s) BMI cut-off for diagnosing obesity even though its validity among Ethiopian population was questioned. To address this problem, a new body mass index cut-off was developed for Ethiopian adults using population-specific data. However, its performance in diagnosing obesity has not been validated. Therefore, this study determined the performance of the newly developed Ethiopian and World Health Organization (WHO) BMI cut-offs in detecting obesity among Ethiopian adults. Methods A cross-sectional study was carried out among 704 employees of Jimma University from February to April 2015. The study participants were selected using simple random sampling technique based on their payroll. Data on sociodemographic variables were collected using an interviewer-administered structured questionnaire. Anthropometric parameters including body weight and height were measured according to WHO recommendation. Body fat percentage (BF%) was measured using the air displacement plethysmography (ADP) after calibration of the machine. The diagnostic accuracy of the WHO BMI cut-off (≥ 30 kg/m2) for obesity in both sexes and Ethiopian BMI cut-off (> 22.2 kg/m2 for males and >  24.5 kg/m2 for females) were compared to obesity diagnosed using ADP measured body fat percentage (> 35% for females and >  25% for males). Sensitivity, specificity, predictive values, and kappa agreements were determined to validate the performance of the BMI cut-offs. Results In males, WHO BMI cut-off has a sensitivity of 5.3% and specificity of 99.4% (Kappa = 0.047) indicating a slight agreement. However, the Ethiopian cut-off showed a sensitivity of 87.5% and specificity of 87.7% (Kappa = 0.752) indicating a substantial agreement. Similarly, in females, the WHO BMI cut-off showed a sensitivity of 46.9%, while its specificity was 100% (Kappa = 0.219) showing a fair agreement. The Ethiopian BMI cut-off demonstrated a sensitivity 80.0% and a specificity 95.6% (Kappa = 0.701) showing a substantial agreement. The WHO BMI cut-off underestimated the prevalence of obesity by a maximum of 73.7% and by a minimum of 28.3% among males, while the values for underestimation ranged from 31.4–54.1% in females. The misclassification was minimal using the newly developed Ethiopian BMI cut-off. The prevalence of obesity was underestimated by a maximum of 9.2% and overestimated by a maximum of 6.2%. The WHO BMI cut-off failed to identify nearly half (46.6%) of Ethiopian adults who met the criteria for obesity using BF% in the overall sample. Conclusions The findings suggest that WHO BMI cut-off (≥ 30 kg/m2) is not appropriate for screening obesity among Ethiopian adults. The newly developed Ethiopian BMI cut-off showed a better performance with excellent sensitivity, specificity, predictive values, and agreement indicating the diagnostic significance of it use as a simple, cost-effective, and valid indicator in clinical and community setups.
