RESUMO
Purpose: To assess the effectiveness of contrast-enhanced mammography (CEM) recombinant images in detecting malignant lesions in patients with extremely dense breasts compared to the all-densities population. Material and methods: 792 patients with 808 breast lesions, in whom the final decision on core-needle biopsy was made based on CEM, and who received the result of histopathological examination, were qualified for a single-centre, retrospective study. Patient electronic records and imaging examinations were reviewed to establish demographics, clinical and imaging findings, and histopathology results. The CEM images were reassessed and assigned to the appropriate American College of Radiology (ACR) density categories. Results: Extremely dense breasts were present in 86 (10.9%) patients. Histopathological examination confirmed the presence of malignant lesions in 52.6% of cases in the entire group of patients and 43% in the group of extremely dense breasts. CEM incorrectly classified the lesion as false negative in 16/425 (3.8%) cases for the whole group, and in 1/37 (2.7%) cases for extremely dense breasts. The sensitivity of CEM for the group of all patients was 96.2%, specificity - 60%, positive predictive values (PPV) - 72.8%, and negative predictive values (NPV) - 93.5%. In the group of patients with extremely dense breasts, the sensitivity of the method was 97.3%, specificity - 59.2%, PPV - 64.3%, and NPV - 96.7%. Conclusions: CEM is characterised by high sensitivity and NPV in detecting malignant lesions regardless of the type of breast density. In patients with extremely dense breasts, CEM could serve as a complementary or additional examination in the absence or low availability of MRI.
RESUMO
PURPOSE: Neutropenia, defined as a number of neutrophils in patients' blood specimen lower than 1500 cells/µm3, is a common adverse event during myelosuppressive oncological chemotherapy, predisposing to febrile neutropenia (FN). Patients with coexisting moderate-to-severe chronic kidney disease (CKD) have an increased risk of FN, included in the guidelines for the primary prophylaxis of FN. However, this does not include mild kidney function impairment with estimated glomerular filtration rate (eGFR) 60-89 ml/min/1.73 m2. This prospective study analyzed the risk of neutropenia in patients on chemotherapy without indication for the primary prophylaxis of FN. METHODS: The study enrolled 38 patients starting chemotherapy, including 26 (68.4%) patients aged 65 years or more. The median duration of follow-up was 76 days. The methodology of creatinine assessment enabled the use of the recommended CKD-EPI formula for identifying patients with a mild reduction of glomerular filtration. RESULTS: Sixteen (42.1%) patients developed at least G2 neutropenia without episodes of FN. Only five (13.1%) patients had eGFR < 60 ml/min/1.73 m2, while 15 (62.5%) eGFR < 90 ml/min/1.73 m2. The relative risk of neutropenia in patients with impaired eGFR was over six times higher than in patients with eGFR > 90 ml/min/1.73 m2 (RR = 6.08; 95%CI:1.45-27.29; p < 0.01). CONCLUSIONS: Our observation indicates that even a mild reduction in eGFR is a risk factor for the development of neutropenia and a potential risk factor for FN.

BACKGROUND: In March 2020 lockdown due to the COVID-19 pandemic forced Polish Medical Universities to implement e-learning. The aim of the study was to evaluate the perception of e-learning by students of Medical Universities in Poland. MATERIAL AND METHODS: Survey was performed nationwide via the Internet from 30th November 2020 to 10th February 2021. Six hundred fifteen (615) medical students completed the survey. The study questionnaire included questions concerning sociodemographic data, perception of lecturers' effectiveness, assessment of stationary and online classes, changes in learning habits and restrictions on education, and advantages and disadvantages of e-learning. RESULTS: The respondents reported that 96.1% of lectures, 85.5% of seminars, and 40.0% of clinical classes were implemented by e-learning. The lectures conducted by e-learning were assessed as good and very good by 78.4% and seminars by 51.2% of respondents. While the clinical classes conducted by e-learning were assessed as bad and very bad by 62.9% of respondents. The most frequently indicated limitations of e-learning were the quality of the content and available materials (26.9%), restrictions in direct contact with the lecturer (19.6%), Internet connection (16.8%), and home conditions (13.8%). Only 4% of the students had to buy or retrofit computer equipment. Any other limitations were indicated by 9.7% of the respondents. CONCLUSIONS: Students were highly accepting of lectures and seminars conducted in the form of e-learning, but not laboratory and clinical classes. The main problems in e-learning are the quality of the classes conducted and the Internet connection. The students expect e-learning classes to be conducted in real-time, with direct, face-to-face contact with the lecturer.

Background and Objectives: Soluble cell adhesion molecules (sCAMs) play a significant role in the metastatic potential of breast cancer (BC). They might block lymphocytes and promote angiogenesis and migration of cancer cells. We assessed the usefulness of sCAMs in the prognosis and monitoring of the progression of advanced BC. Materials and Methods: We assessed soluble E-selectin, P-selectin, VCAM-1, ICAM-1, EpCAM, IL-6Ra, TNF-R1, and TNF-R2 in 39 women with aBC. Blood samples were obtained at the beginning of the treatment and after 2 months. Results: The median progression-free survival (PFS) was 9 months, and overall survival (OS) was 27 months. The higher levels of sICAM-1 (HR = 2.60, p = 0.06) and lower levels of sEpCAM (HR = 2.72, p < 0.05) were associated with faster progression of aBC. High levels of sEpCAM through the follow-up period were significantly associated with a lower risk of progression (HR = 0.40, p < 0.01). We found the independent predictive value of higher than median sICAM-1 levels for PFS (HR = 2.07, p = 0.08) and of sVCAM-1 levels for OS (HR = 2.59, p < 0.05). Conclusions: Our data support the predictive value of sICAM-1 and sVCAM-1 and suggest that they could become markers for tailoring new therapies in aBC. sEpCAM level could be used as an early indicator of response to the therapy.

BACKGROUND AND AIMS: Vitamin D (VD) deficiency is considered an important risk factor for the development of atherosclerosis and aortic aneurysms. The deficiency is claimed to enhance degeneration and remodeling of collagen and elastin fibers in the artery wall, leading to its weakening and progressive dilatation. This study aimed to assess vitamin D status, in outpatients with abdominal aneurysms (AAA) and peripheral artery disease (PAD) not treated with VD, and factors affecting serum 25-OH-D levels. METHODS AND RESULTS: This cross-sectional study involved 59 outpatients with AAA and 150 with PAD. AAA was defined as local dilation of the aorta diameter >30 mm in imaging. None of the patients was prescribed VD containing medicines. Serum 25-OH, iPTH, phosphorus and calcium levels were assessed in all study participants. VD status was categorized according to commonly used cut-offs for serum 25-OH-D (<20 ng/mL - deficiency, <30 ng/mL -insufficiency). Serum 25-OH-D levels were similar in patient with AAA and PAD [1-3Q: 26.2 (18.8-37.6) vs 21.8 (15.9-31.4) ng/mL; p = 0.30], with deficiency noted in 25.4% with AAA and 41.8% with PAD (p < 0.05). Multiple regression analysis revealed that VD deficiency was explained by past stroke episodes [OR = 2.80 (95%CI: 1.22-6.41)]. Secondary hyperparathyroidism was diagnosed in 1.7% of patients with AAA and 1.9% with PAD. CONCLUSIONS: The frequency of VD deficiency in outpatient with AAA is not greater than in those with PAD. Past stroke episode is associated with an increased occurrence of VD deficiency in both outpatients with AAA and PAD other than sun exposure and diet.

BACKGROUND: Various factors motivate people to undertake treatment for obesity. Among others they include health benefits, willingness to please others, and dissatisfaction with one's appearance. The present study aimed to assess body size dissatisfaction in patients with obesity seeking and not seeking treatment for obesity. METHODS: Two-hundred-sixteen adult subjects (154 women, 62 men) including 80 people with BMI ≥ 30 kg/m2 starting treatment for obesity (BMI 35.7 ± 5.3 kg/m2) and 136 volunteers with obesity (BMI 34.7 ± 4.3 kg/m2) not seeking treatment for obesity, were enrolled. Body size satisfaction was assessed using the Figure Rating Scale adapted by Stunkard. RESULTS: Patients with obesity starting obesity treatment had more often a high level of body size dissatisfaction than volunteers with obesity not seeking the treatment (p < 0.001). There was a significant difference in the distribution of body size dissatisfaction in women (p < 0.05), but not in men (p = 0.47). CONCLUSION: Patients with obesity, especially women, seeking obesity treatment more often represent a high level of body size dissatisfaction than volunteers with obesity not seeking treatment for obesity. This implies the need for public health campaigns to address negative attitudes or misconceptions about obesity and its treatment. Placing more attention and emphasis on body size dissatisfaction in more vulnerable women with obesity may help to define personal motivations and goals, strengthen the doctor-patient relationship and better adapt therapeutic strategies.

AIM: The aim of the study was to assess the influence of the number of hours of daily nursing care for NHPPD in medical departments on missed care and the correlation between NHPPD and in-hospital mortality. BACKGROUND: Patient mortality can be a consequence of missed care as it correlates with the nurse-patient ratio. One of the methods to measure missed care is the Nursing Hours per Patient Day rating. METHODS: The study sample included 44,809 patients including 971 deaths in 8 wards. The influence of nursing hours, nursing education, and the percentage of patients' classification on in-hospital mortality were evaluated with backward stepwise linear regression. RESULTS: One hour added to the average NHPPD in medical departments was related to a decrease in mortality rate by 6.8 per 1,000 patient days and a lower chance for the emergence of unplanned death by 36%. CONCLUSIONS: The number of NHPPD and the percentage of professional nurses are factors influencing missed care and in-hospital mortality. IMPLICATIONS FOR NURSING MANAGEMENT: The severe consequences of missed care, that is mortality, and the correlation between in-hospital mortality, nursing education and nursing-patient ratio, which are indicators of care quality, are arguments for maintaining adequate staffing levels to avoid missed care.

INTRODUCTION: The psychological profile of obese people deciding to start obesity treatment may be different from those not choosing to seek the therapy. Previous studies have shown a higher incidence of depression in obese than in normal weight people. However, data are lacking concerning the occurrence of depressive symptoms and their severity in obese subjects who do or do not decide to start treatment for obesity. Therefore, the aim of this study was to evaluate the prevalence and severity of depressive symptoms among obese people starting treatment and not seeking treatment for obesity. MATERIALS AND METHODS: Enrolled subjects were 331 adults (241 women, 90 men), including 193 obese subjects starting treatment for obesity (46.8 ± 13.2 years, BMI 37.6 ± 5.5 kg/m2) and 138 obese volunteers never seeking treatment for obesity (44.3 ± 12.5 years, BMI 34.7 ± 4.3 kg/m2). Depression levels were determined using the Beck Depression Inventory (BDI). RESULTS: The level of depression was significantly higher among those starting treatment for obesity than those never seeking treatment for obesity (13.2 ± 9.2 vs. 9.5 ± 7.9 points; p < 0.001). This difference was statistically significant in women (14.4 ± 9.2 and 11.0 ± 8.2 points, respectively; p < 0.01), but not in men (7.2 ± 6.4 and 7.3 ± 7.1 points, respectively; p = 0.95). There were more women with moderate/severe depressive symptoms in the group starting treatment than in the group not seeking treatment for obesity (44.7 and 24.4%, respectively). No such difference was observed in men. CONCLUSIONS: Obese subjects, especially women, with depressive symptoms are more likely to start treatment for obesity. LEVEL OF EVIDENCE: Level III, case-control analytic study.

BACKGROUND: Direct-acting antivirals (DAAs), including sofosbuvir (SOF), are recommended for treatment of chronic hepatitis C virus (HCV) infection. However, few studies have investigated the effectiveness and safety of new DAAs in kidney transplant recipients (KTRs). OBJECTIVES: To assess the effectiveness and safety of SOF-based therapy in stable KTRs. PATIENTS AND METHODS: Forty KTRs were treated with SOF-based regimens. Rapid, end-therapeutic, and sustained virologic responses were assessed, as was liver stiffness by elastometry. Safety was monitored by measuring the estimated glomerular filtration rate (eGFR), blood hemoglobin (Hb) concentration, proteinuria, and blood trough levels of calcineurin inhibitors (CNIs). Other side effects were also recorded. RESULTS: The effectiveness of DAAs was 100% at all time points. The therapy did not significantly influence eGFR or proteinuria, but significantly decreased mean blood Hb levels (13.5 ± 2.0 vs 11.6 ± 1.9, respectively, P < 0.001), which required a dose reduction or cessation of ribavirin (RBV) in 50% of patients. A profound, significant decrease in initial CNI concentrations was also observed during treatment in the majority of patients within the first month of therapy. CONCLUSIONS: In this cohort of KTRs, the new SOF-based therapies were characterized by 100% effectiveness and good safety profiles. However, in patients co-treated with RBV, close blood Hb monitoring and early RBV dose reduction are necessary. In the majority of KTRs, antiviral therapy leads to a substantial and early decrease in CNIs levels, thus frequent measurement of CNI levels is necessary during SOF-based therapy.

BACKGROUND: Elevated circulating osteoprotegerin (OPG) level is associated with an increased risk of hospitalization for ischemic stroke and coronary artery disease. The aim of the present study was to analyze whether OPG assessment may improve the prediction of mortality in patients with stroke. PATIENTS AND METHODS: Serum OPG, fetuin A, 25-OH-D3, intact parathyroid hormone levels were assessed in serum samples which were left over after routine tests in a hospital laboratory. This assessment was conducted in 240 consecutive patients with acute ischemic stroke, admitted within 24hours after the onset of symptoms to the Stroke Unit. Mortality data were obtained from the local registry office. RESULTS: The mean OPG serum level was 14.6 ± 6.0pmol/L (range: 3.7-43.4). There were no significant differences in the OPG values between men and women (13.9 ± 5.0 versus 15.1 ± 6.7 pmol/L; P = .12). Therefore, tertiles were calculated for the whole group. During the follow-up, 85 (35.4%) patients died and 92 (38.3%) died or had recurrent stroke. OPG level appeared a significant predictors of death and composite end-point (death/recurrent stroke), in addition to the well-established once (age, atrial fibrillation, diabetes RANKIN at admission and discharge, severity of stroke). In multivariable stepwise backward analyses, the OPG level persisted as a significant and independent predictor of death (hazard ratio [HR]â¯=â¯1.084 (95% confidence intervals: 1.036-1.134)] and composite and point (HRâ¯=â¯1.082 [1.037-1.129]). CONCLUSIONS: OPG level may be considered as a predictor of mortality in stroke patients.

Background and objectives: Patients diagnosed with incidentally found adrenal tumors (incidentaloma) that do not meet the criteria for surgical treatment require follow-ups with repeated imaging. The aim of this study is to compare the accuracy of the measurements of the adrenal tumor size in ultrasound (US) with and without contrast in comparison to computed tomography (CT) or magnetic resonance (MRI). Further, this study attempts to answer the question of whether contrast-enhanced ultrasound (CEUS) can improve imaging accuracy and replace CT/MRI in the monitoring of patients with adrenal tumors. Materials and Methods: The retrospective analysis included 79 adult patients with adrenal incidentalomas not exceeding a dimension of 6 cm who underwent a CT or MRI scan, US, and CEUS with the use of SonoVue in two-dimensional (2D) and three-dimensional (3D) projections and Doppler techniques. Tumor vascularization in CEUS was classified as follows: peripheral, peripheral-central, central, or poor. Results: Of 79 adrenal tumors, 48.1% showed peripheral, 29.1% showed poor, 21.5% showed peripheral-central, and only 1.3% showed central vascularization. The median volume of tumors detected with CEUS (69.9 cm3) was significantly higher than with US (44.5 cm3) and CT or MRI (57.1 cm3). The relative error of the adrenal volume with CEUS compared with CT or MRI was significantly higher than with standard US, regardless of the type of tumor vascularization. Conclusions: CEUS does not improve the accuracy of adrenal tumor size assessment regardless of the type of vascularization.

OBJECTIVE: Oxidized cholesterol derivatives are thought to exert atherogenic effect thus adversely affecting vascular endothelium. The aim of the study was to assess the effect of 5α,6α-epoxycholesterol on experimentally induced hypercholesterolemia in rabbits, and the levels of homocysteine (HCY), asymmetric dimethylarginine (ADMA), paraoxonase-1 (PON-1), and inflammatory parameters (IL-6, TNF-α, CRP). MATERIAL AND METHODS: The rabbits were divided into 3 groups, 8 animals each, and fed with basic fodder (C), basic fodder plus cholesterol (Ch) or basic fodder plus 5α,6α-epoxycholesterol, and unoxidized cholesterol (ECh). Serum concentrations of studied parameters were determined at 45-day intervals. The study was continued for six months. RESULTS: We demonstrated that adding 5α,6α-epoxycholesterol to basic fodder significantly affected lipid status of the experimental animals, increasing total cholesterol and LDL cholesterol levels, as well as HCY and ADMA levels, whilst leaving the PON-1 activity unaffected. Additionally, the ECh group presented with significantly higher concentrations of inflammatory biomarkers (IL-6, TNF-α, and CRP). In the Ch group, lower yet significant (as compared to the C group) changes of levels of studied parameters were observed. CONCLUSION: Exposure of animals with experimentally induced hypercholesterolemia to 5α,6α-epoxycholesterol increases dyslipidaemia, endothelial dysfunction, and inflammatory response.

BACKGROUND: The available literature suggests that circulating visfatin/Nicotinamide Phosphoribosyltransferase (NAMPT) level variability in humans is related to obesity, insulin resistance, inflammation, and lipid profile. The aim of the study was to assess the relationship between circulating visfatin/NAMPT, obesity, insulin resistance, inflammation, and lipid profile in a large population-based, elderly cohort, applying structural equation modeling. MATERIALS AND METHODS: The analysis included 2983 elderly participants of the PolSenior study with assessed total blood count, fasting concentrations of lipids, glucose, insulin, hs-CRP, interleukin-6, and visfatin/NAMPT (by ELISA), and calculated HOMA-IR. RESULTS: The circulating visfatin/NAMPT levels were higher in obese compared to normal weight subjects, in those with hs-CRP above 3 mg/L, with low serum HDL cholesterol, and in insulin resistant subjects. Based on results of the exploratory factor analysis, a baseline model of mutual relationship between four latent and measured variables was created and a final model was developed by maintaining only two significant categories. The important variables for 'latent inflammation' proved to be hs-CRP and IL-6 serum levels. In the case of 'nutritional status', important variables were BMI, waist circumference, and to a lesser extent insulin resistance. Additionally, the residual correlation between those two constructs was also statistically significant. CONCLUSION: The structural equation modeling provided support for the existence of a link between nutritional status, inflammation and circulating visfatin/NAMPT level. This indicates that circulating visfatin/NAMPT can be considered as a novel surrogate marker of systemic inflammation associated with fat depot, especially visceral, in the elderly population.

Background: Given the growing evidence for an environmental contribution to the etiology of Parkinson's disease (PD), searching for local and regional differences in PD prevalence in multiple areas across the world may further clarify the role of environmental toxins. Objective: To provide local and regional prevalence estimates of PD in Poland. Methods: We analyzed the prevalence of PD and its trend over the last decade (2010 to 2019) based on data from the National Health Fund in Poland. We specifically examined sex differences in PD prevalence, as well as differences across Polish regions. Results: During the above period, the prevalence of PD in Poland increased from 226 per 100,000 to 269 per 100,000 inhabitants. Unexpectedly, we found that PD was 1.2-times more common in women than men. The increase in prevalence over the past decade was different between both sexes: an increase from 250 to 283 per 100,000 for women (13.3% increase), and from 200 to 254 per 100,000 for men (27.1% increase). In addition, we observed differences in prevalence across different Polish regions, with some regions having up to 51% lower prevalence rates than others. Conclusions: The prevalence of PD in Poland is in line with previously reported prevalence rates across Europe. However, unlike the situation in most of the world, PD was more prevalent in women than men. We discuss several possible explanations as well as potential measures that might help to reduce the growth of PD.

The prediction of colorectal cancer (CRC) response to palliative chemotherapy (CTH) is still difficult. Patients at a higher risk of progression may benefit from more aggressive treatment. This study assessed the predictive value of prolactin (PRL) and a panel of cytokines, chemokines, and growth factors for the risk of rapid progression in CRC patients starting palliative CTH. This study included 51 CRC patients initiating palliative CTH with up to 5-year follow-up, divided into rapid and non-rapid progressors. Serum samples were collected before CTH for assessment of a large panel of cytokines, chemokines, growth factors, and PRL via a multiplex method. Rapid progressors (N = 19) were characterized by increased baseline values of IL-8 and IP10 but decreased PRL levels. In addition, PRL below 18.2 ng/mL was a strong predictor of weight loss during CTH. Grade 3 (HR = 2.97; 95%CI: 1.48-5.98) and PRL level (HR = 0.96; 95%CI: 0.91-1.01) were independent risk factors of progression. We showed that CRC rapid progressors are characterized by decreased baseline PRL levels. In addition, increased baseline levels of IP-10, sHER-2, IL-6, and IL-8 may be associated with longer survival; however, larger studies are needed to confirm their predictive role in CRC patients.
RESUMO
PURPOSE: Analysis of the morphology of lesions classified into the BI-RADS 4 category and assessment of the possibility of downgrade the BI-RADS category in those that did not show enhancement on recombinant contrast-enhanced mammography (CEM) images. METHOD: The retrospective, single-center study included 528 patients who underwent a core needle biopsy performed from January 2017 to November 2022 due to a breast lesion classified as BI-RADS 4 on CEM. Patients' electronic records and imaging examinations were reviewed. Individual lesions were classified into the morphological categories of mass, non-mass, and microcalcifications. Sensitivity, specificity, positive as well as negative predictive values were calculated for the whole group and individual morphological categories. The influence of the lesions' diameter on the results was analyzed. RESULTS: CEM NPV for the whole group was 93.9% (±95% CI: 90.0-96.4), for mass lesions 100% (±95% CI: 94.5-100), for non-mass lesions 97.8% (±95% CI: 87.0-99.9) and 87.9% (±95% CI: 80.3-93.0) for microcalcifications. Given that 230 out of 383 benign lesions were not contrast-enhancing, 60.1% of unnecessary CNBs would have been correctly avoided. CEM sensitivity for lesions < 20 mm was lower than for lesions ≥ 20 mm and was respectively 86.6% (±95% CI: 76.8-92.8) vs 94.6% (±95% CI: 86.0-98.2), respectively. CONCLUSION: CEM is characterized by high sensitivity in the detection of malignant lesions in the case of lesions with mass and non-mass morphology. The high NPV for recombinant images suggests that in the case of these lesions, the lack of enhancement supports the benign nature of the lesion and may lead to a downgrade of the BI-RADS category.

The external health locus of control (HLC) is based on an assumption that obtained health results depend on the influences of external factors. As for the internal HLC-that is the effect of our own actions and capabilities. Little is known regarding how the HLC can influence body weight or the occurrence of visceral obesity. The study aimed to assess the relationship between the health locus of control and nutritional status in adults. The study included 744 adults (452 women, 292 men; 2.8% underweight, 43.8% normal weight, 29.7% overweight, and 23.7% obese). In addition to anthropometric measurement and socio-demographic data, the health locus of control, using the Multidimensional Health Locus of Control Scale (MHLC) by Wallston K, Wallston B, and DeVellis R, was assessed. The percentage of subjects with an internal HLC did not differ significantly between obese, overweight, and normal-weight groups. However, the percentage of subjects with an external HLC-dependent on the impact of others-was significantly higher in both men and women with obesity than in corresponding overweight and normal-weight groups (p < 0.01). Yet, the percentage of subjects with an external HLC subject to the impact of chance was significantly higher among overweight and obese women than in those of normal weight (p < 0.05) only. Women with overweight or obesity, with external health locus of control, experienced both the impact of others and of chance more often than women with normal weight. However, men with overweight and with obesity more often had external health locus of control influenced only by others.

Soluble cell adhesion molecules (sCAMs) are involved in the development of neoplastic diseases. sCAMs can block lymphocytes and promote angiogenesis and migration of breast cancer (BC) cells. Interleukin 6 (IL-6) and tumor necrosis factor α (TNF-α) enhance metastatic potential via upregulation of CAMs. We assessed soluble interleukin-6 receptor subunit alpha (IL-6Ra), TNF-R1, TNF-R2, E-selectin, P-selectin, VCAM-1, ICAM-1, and EpCAM in 89 women with stage I-III BC and 28 healthy women. Blood samples were obtained at the beginning of neoadjuvant/induction (N = 49) or adjuvant treatment (N = 40), and after 2 months. Surgery revealed complete response in 29.4% of patients, partial response in 67%, and stable disease in 5.9%. Achieving a pathological response was 4 times greater for baseline levels of sIL-6Ra >5.63 ng/mL [odds ratio (OR) = 4.1, 95% confidence interval (CI): 0.8-20.4, P = 0.08] and more than 6 times for soluble tumor necrosis factor receptor 1 (sTNF-R1) ≥ 0.97 ng/mL (OR = 6.2, 95% CI: 1.2-32.3, P < 0.05). Compared with the control group, serum sP-selectin, soluble epithelial cell adhesion molecule (sEpCAM), and sTNF-R2 concentrations were significantly higher in patients who started adjuvant therapy (P < 0.05) and preoperative therapy (P < 0.01). Baseline serum sIL-6Ra concentrations were significantly higher in patients before surgery than in patients after tumor resection (P < 0.05), independent of the follow-up time. The baseline serum soluble receptors of IL-6 (sIL-6R) and TNF-α (sTNF-R1) concentrations have a predictive value for preoperative therapy in patients with BC.
RESUMO
Background: Thoracic surgery often demands separation of ventilation between the lungs. It is achieved with double-lumen tubes (DLTs), video double-lumen tubes (VDLTs) or bronchial blockers. We tested the hypothesis that intubation with the VivaSight double-lumen tube would be easier and faster than with a standard DLT. Methods: Seventy-one adult patients undergoing thoracic procedures that required general anaesthesia and one-lung ventilation (OLV) were enrolled in this randomized, prospective study. Patients were randomly assigned to procedure of intubation with a standard DLT or VDLT. The collected data included: patients' demographics, surgery information, anthropometric tests used for difficult intubation prediction, specifics of intubation procedure, tube placement, fiberoptic bronchoscopy (FOB) use, lung separation, trachea temperature, and reported complications of intubation. Results: For DLTs compared to video-double lumen tubes, intubation time was significantly longer (125 vs. 44 s; P<0.001), intubation graded harder (P<0.05) and FOB use was more prevalent [8 (20.5%) vs. 0; P<0.05]. Conclusions: The use of VDLTs when compared with standard-double lumen tubes offers reduced intubation time and is relatively easier. Also, the reduced need for fibreoptic bronchoscopy may improve the cost-effectiveness of VDLT use. In addition, constant visualization of the airways during the procedure allows to quickly correct or even prevent the tube malposition. Trial Registration: ClinicalTrials.gov Identifier: NCT04101734.
RESUMO
PURPOSE: Comprehensive rehabilitation in patients with severe periodontal destruction may require the use of dental implants. The primary aim of this study was to evaluate bone volume changes in periodontally compromised patients over a 12-month follow-up period after immediate full-arch implant reconstruction of the mandible. The secondary aim was to evaluate the repeatability of 3D bone volume change measurement methods around dental implants. The null hypothesis was that bone volume would decrease in the first year after delivery of the definitive prosthetic reconstruction. MATERIALS AND METHODS: This retrospective study analyzed CBCT scans of 16 patients before and after computer-guided immediate full-arch implant reconstruction of the mandible. The bone volume change in the mandibular body and around the implants and the peri-implant bone area in coronal and axial cross sections were calculated. RESULTS: The average bone gain for the mandibular body was 3.3% ± 1.8%. The average bone volume increase in the peri-implant area was 23.2% ± 16.7%. The interobserver and intraobserver ICC values for 3D measurements were high (> 0.85). CONCLUSION: The null hypothesis was rejected. Both mandibular body and peri-implant surroundings undergo bone remodeling in the form of bone gain over 12 months after immediate implantation.
