RESUMO

BACKGROUND: A 21-year-old woman diagnosed with cystic fibrosis developed cirrhosis, exocrine pancreatic insufficiency, and insulin-dependent diabetes mellitus. The patient qualified for double organ liver-pancreas transplantation beyond typical indications. The respiratory symptoms of cystic fibrosis were moderate and well-treated. The patient was endangered mainly by liver insufficiency and recurrent hypoglycemia, which was due to the treatment of diabetes with high doses of insulin. Computed tomography showed mild bronchiectasis, cirrhotic liver, splenomegaly, and atrophy of the pancreas. Pseudomonas aeruginosa colonized the upper respiratory tract. Gastrointestinal complications were sufficient for the patient to be qualified for combined liver-pancreas transplantation. METHODS: First, a standard hepatectomy was performed. The liver was transplanted orthotopically. Subsequently, the team performed pancreas transplantation through a separate incision. The donor's duodenum was anastomosed to the recipient's jejunum, close to the ligament of Treitz. RESULTS: No serious complications were noted during the postoperative period. Transplanted organs started functioning without delay. The patient was discharged after 6 weeks in general good condition. Twenty months later, the patient felt well, and the grafts kept functioning properly. CONCLUSION: Combined liver-pancreas transplantation in patients with CF restores exocrine and endocrine pancreatic function and minimizes the risk of life-threatening complications associated with liver insufficiency. Improvement of life quality coincides with the possibility of discontinuing insulin and pancreatic enzyme supplementation. The combination of liver and pancreas transplantation may prevent advanced pulmonary complications, extend the prognosis of survival, and improve the long-term life quality.

RESUMO

The similarity of the clinical picture of metabolic syndrome and hypercortisolemia supports the hypothesis that obesity may be associated with impaired expression of genes related to cortisol action and metabolism in adipose tissue. The expression of genes encoding the glucocorticoid receptor alpha (GR), cortisol metabolizing enzymes (HSD11B1, HSD11B2, H6PDH), and adipokines, as well as selected microRNAs, was measured by real-time PCR in adipose tissue from 75 patients with obesity, 19 patients following metabolic surgery, and 25 normal-weight subjects. Cortisol levels were analyzed by LC-MS/MS in 30 pairs of tissues. The mRNA levels of all genes studied were significantly (p < 0.05) decreased in the visceral adipose tissue (VAT) of patients with obesity and normalized by weight loss. In the subcutaneous adipose tissue (SAT), GR and HSD11B2 were affected by this phenomenon. Negative correlations were observed between the mRNA levels of the investigated genes and selected miRNAs (hsa-miR-142-3p, hsa-miR-561, and hsa-miR-579). However, the observed changes did not translate into differences in tissue cortisol concentrations, although levels of this hormone in the SAT of patients with obesity correlated negatively with mRNA levels for adiponectin. In conclusion, although the expression of genes related to cortisol action and metabolism in adipose tissue is altered in obesity and miRNAs may be involved in this process, these changes do not affect tissue cortisol concentrations.

RESUMO

BACKGROUND Patients with obesity with interstitial lung diseases (ILD) are encouraged to lose weight, as it improves lung function and lung transplant eligibility. As exercise tolerance in these patients is low and weight gain is a common adverse effect of corticosteroids, bariatric surgery can be an effective method for the management of obesity in this patient group. However, perioperative complications in such high-risk patients remain a concern. Therefore, we aimed to demonstrate successful anesthetic management for obese patients with ILD, which may be practically utilized to reduce perioperative pulmonary complications and improve outcomes. CASE REPORT Our case report presents a 42-year-old man with ILD who underwent laparoscopic sleeve gastrectomy (LSG). Preoperative studies revealed severe restrictive disease, right ventricular overload with assessed intermediate risk of pulmonary hypertension, and heart failure, with preserved left ventricle fraction but with poor exercise tolerance. Patient had opioid-free anesthesia (OFA) and postoperative multimodal analgesia. Following a 24-h stay in the Post-Anesthesia Care Unit, the patient was transferred to the ward and ultimately discharged home 2 days thereafter. At the 1-year follow-up, the patient reduced his weight by 40 kg and reported a significant improvement in physical capacity. CONCLUSIONS Our record demonstrates that OFA can be successfully used in high-risk patients with ILD undergoing LSG. In a period of a year, the patient improved so much that he no longer required lung transplantation, which may encourage clinicians to provide bariatric surgery using the OFA technique in the population of patients with obesity and severe respiratory illness.

RESUMO

The advanced glycosylation end-product receptor (AGER) is involved in the development of metabolic inflammation and related complications in type 2 diabetes mellitus (T2DM). Tissue expression of the AGER gene (AGER) is regulated by epigenetic mediators, including a long non-coding RNA AGER-1 (lncAGER-1). This study aimed to investigate whether human obesity and T2DM are associated with an altered expression of AGER and lncAGER-1 in adipose tissue and, if so, whether these changes affect the local inflammatory milieu. The expression of genes encoding AGER, selected adipokines, and lncAGER-1 was assessed using real-time PCR in visceral (VAT) and subcutaneous (SAT) adipose tissue. VAT and SAT samples were obtained from 62 obese (BMI > 40 kg/m2; N = 24 diabetic) and 20 normal weight (BMI = 20-24.9 kg/m2) women, while a further 15 SAT samples were obtained from patients who were 18 to 24 months post-bariatric surgery. Tissue concentrations of adipokines were measured at the protein level using an ELISA-based method. Obesity was associated with increased AGER mRNA levels in SAT compared to normal weight status (p = 0.04) and surgical weight loss led to their significant decrease compared to pre-surgery levels (p = 0.01). Stratification by diabetic status revealed that AGER mRNA levels in VAT were higher in diabetic compared to non-diabetic women (p = 0.018). Elevated AGER mRNA levels in VAT of obese diabetic patients correlated with lncAGER-1 (p = 0.04, rs = 0.487) and with interleukin 1ß (p = 0.008, rs = 0.525) and resistin (p = 0.004, rs = 0.6) mRNA concentrations. In conclusion, obesity in women is associated with increased expression of AGER in SAT, while T2DM is associated with increased AGER mRNA levels and pro-inflammatory adipokines in VAT.

RESUMO

Over recent years, the global healthcare system has experienced a notable increase in the prevalence of obesity and its associated health complications such as hypertension, type 2 diabetes, lipid disorders, etc. What is more, one of the significant phenomena is the increasing demand for bariatric procedures among individuals of working age due to the high prevalence of type III obesity and type II obesity with co-morbidities. This trend is pronounced in Poland, due to the increasing number of patients meeting the qualifying criteria for surgery among professionally active and inactive patients. The aim of this study is to characterize the alarmingly high number of candidates for bariatric procedures among professionally active Poles. In total, the results of 2,056,861 initial, control, and periodic visits as part of the occupational medicine certificate were analyzed-collected from 1,342,749 unique patients (51.7% men; mean age of whole group: 36.81, SD = 10.91). Statistical calculations were performed, qualitative data were assessed using percentage and occurrence counts, while qualitative data were described using mean (M), standard deviation (SD), median, skewness, kurtosis, and range values. Results with p < 0.05 were deemed significant. Chi-square analysis and one-way ANOVA (with Scheffe's post hoc test) were employed. Charts were created in the R program. It was noticed that there was a consistent rise in the proportion of individuals classified as candidates for bariatric procedures (an increase of 0.3%) alongside a notable decrease in the percentage of individuals maintaining a healthy body weight. Moreover, it is imperative to conduct yearly evaluations of the prevalence of obesity and its associated health conditions. It should be noted that hypertension occurred in 42.2% of patients, type 2 diabetes in 6.2% of patients, and lipid disorders in 8.4% of patients with third-degree obesity. This proactive approach is essential in order to adequately equip the healthcare system to address the increasing population of obese individuals, especially candidates for bariatric procedures.

RESUMO

Anesthesia for laparoscopic sleeve gastrectomy and perioperative management remains a challenge. Several clinical studies indicate that opioid-free anesthesia (OFA) may be beneficial, but there is no consensus on the most optimal anesthesia technique in clinical practice. The aim of our study was to assess the potential benefits and risks of intraoperative OFA compared to multimodal analgesia (MMA) with remifentanil infusion. In a prospective, randomized study, we analyzed 59 patients' data. Primary outcome measures were oxycodone consumption and reported pain scores (numerical rating scale, NRS) at 1, 6, 12, and 24th hours after surgery. Postoperative sedation on the Ramsay scale, nausea and vomiting on the PONV impact scale, desaturation episodes, pruritus, hemodynamic parameters, and hospital stay duration were also documented and compared. There were no significant differences in NRS scores or total 24-h oxycodone requirements. In the first postoperative hour, OFA group patients needed an average of 4.6 mg of oxycodone while the MMA group 7.72 mg (p = 0.008, p < 0.05 statistically significant). The PONV impact scale was significantly lower in the OFA group only in the first hour after the operation (p = 0.006). Patients in the OFA group required higher doses of ephedrine 23.67 versus 15.69 mg (p = 0.039) and more intravenous fluids 1160 versus 925.86 ml (p = 0.007). The mode of anesthesia did not affect the pain scores or the total dose of oxycodone in the first 24 postoperative hours. Only in the first postoperative hour were an opioid-sparing effect and reduction of PONV incidence seen in the OFA group when compared with remifentanil-based anesthesia. However, patients in the OFA group showed significantly greater hemodynamic lability necessitating higher vasopressor doses and more fluid volume.

RESUMO

Smoking is a leading cause of preventable mortality. It affects both the health and economic situation within societies. The aim of the study is to perform an epidemiological analysis of smoking among professionally active adults in Poland in the years 2016-2020 and its Strong Relationship with Cardiovascular Co-morbidities. The article retrospectively analyzed the records of 1,450,455 who underwent occupational medicine examinations between 2016 and 2020. Statistical analyses performed using IBM SPSS Statistics 25 software were performed. In general, irrespective of the year of measurement, 11.6% of women and 17.1% of men declared smoking. After sorting by year of measurement, we found that the percentage of female smokers was decreasing, while that of males remained relatively consistent. In the case of BMI, it was found that among tobacco smokers the percentage of people with normal body weight decreases with successive years of measurement, while the percentage of overweight and level I obesity increases. Moreover, we analyzed in detail the occurrence of particular comorbidities in the group of people who declared smoking. The most common diseases in this group were: arterial hypertension (39%), lipid disorders (26.7%), and hypertension and lipid disorders (16.5%). Active preventive measures are necessary to reduce the number of smokers and the negative impact of smoking on the occurrence of comorbid diseases.

RESUMO

Estrogen affects adipose tissue function. Therefore, this study aimed at assessing changes in the transcriptional activity of estrogen receptor (ER) α and ß genes (ESR1 and ESR2, respectively) in the adipose tissues of obese individuals before and after weight loss and verifying whether epigenetic mechanisms were involved in this phenomenon. ESR1 and ESR2 mRNA and miRNA levels were evaluated using real-time PCR in visceral (VAT) and subcutaneous adipose tissue (SAT) of 78 obese (BMI > 40 kg/m2) and 31 normal-weight (BMI = 20−24.9 kg/m2) individuals and in 19 SAT samples from post-bariatric patients. ESR1 and ESR2 methylation status was studied using the methylation-sensitive digestion/real-time PCR method. Obesity was associated with a decrease in mRNA levels of both ERs in SAT (p < 0.0001) and ESR2 in VAT (p = 0.0001), while weight loss increased ESR transcription (p < 0.0001). Methylation levels of ESR1 and ESR2 promoters were unaffected. However, ESR1 mRNA in the AT of obese subjects correlated negatively with the expression of hsa-miR-18a-5p (rs = −0.444), hsa-miR-18b-5p (rs = −0.329), hsa-miR-22-3p (rs = −0.413), hsa-miR-100-5p (rs = −0.371), and hsa-miR-143-5p (rs = −0.289), while the expression of ESR2 in VAT correlated negatively with hsa-miR-576-5p (rs = −0.353) and in SAT with hsa-miR-495-3p (rs = −0.308). In conclusion, obesity-associated downregulation of ER mRNA levels in adipose tissue may result from miRNA interference.

RESUMO

Pancreas transplantation is considered a high-risk surgery with cardiovascular complications. Early detection of all potential cardiovascular risk factors can decrease the perioperative risk and improve the pancreas recipients' outcome. The present study aims to evaluate the association between serum uric acid (UA) levels and the prevalence of coronary artery disease (CAD) in patients eligible for pancreas transplantation. We prospectively enrolled 63 consecutive patients with type 1 diabetes (T1D) who underwent cardiological evaluation before pancreas transplantation in our center. Participants underwent clinical evaluation, laboratory assays, and coronary angiography. The median concentration of UA in patients with CAD was significantly higher than in participants without CAD (6.43 (4.93-7.26) vs. 4.41 (3.64-5.49) mg/dL, p = 0.0002). We showed the positive correlation between UA concentration and systolic blood pressure, pulse pressure (PP) and triglycerides (r = 0.271, p = 0.032; r = 0.327, p = 0.009; r = 0.354, p = 0.004, respectively). In a multivariate analysis, the concentration of UA (OR 2.044; 95% CI: 1.261-3.311, p = 0.004) was independently associated with the prevalence of CAD in pancreas transplant candidates with T1D. We demonstrated that elevated UA levels were strongly associated with the high prevalence of CAD in pancreas transplant candidates with T1D. To stratify cardiovascular risk, the measurement of the UA concentration should be considered in all T1D patients qualified for pancreas transplantation.

RESUMO

Liver transplantation (LTx) is the best treatment for patients with early-stage hepatocellular carcinoma (HCC). The Milan criteria positively influenced results of liver transplantation and were adopted by the majority of cancer centers, becoming the criterion standard treatment for early-stage HCC. Despite the use of restrictive criteria, recurrence is still high, affecting between 8% and 20% of cases, and is a significant predictor of survival after LTx. The diagnosis of both micro-and macro-invasion of vessels, which are significant factors in determining the frequency of recurrence and overall survival, significantly decreases the success of transplantation, causing an increase in mortality of 50% in comparison to recipients with no vascular invasion. The risk of recurrence depends on several factors, which are discussed in this review. The authors also discuss the clinical presentation and treatment methods of recurrence and its prognosis. In addition, the role of different models developed to identify groups of patients with high versus low risk of recurrence is discussed, enabling the planning of recommendations and screening protocols after transplantation to help early diagnosis and guide effective treatment. In the era of an increasing numbers of liver transplants due to HCC, the need to create robust screening tools is urgent.

RESUMO

BACKGROUND: As a restrictive procedure, laparoscopic sleeve gastrectomy (LSG) relies primarily on the reduction of gastric volume. It has been suggested that an immediate postoperative gastric remnant volume (GRV) may influence long-term results of LSG; however, there are no consensus in this matter. The aim of this study was to assess the reproducibility of different radiographic methods of GRV calculation and evaluate their correlation with the weight loss (WL) after surgery. METHODS: This retrospective study evaluated 174 patients who underwent LSG in the period from 2014 to 2017. Using UGI, GRV was measured with 3 different mathematical methods by 2 radiologists. Intraobserver and interobserver calculations were made. Correlation between GRV and WL were estimated with calculations percentage of total weight loss (%TWL) and percentage of excess weight loss (%EWL) after 1, 3, 6, 12, 18, and 24 months postoperatively. RESULTS: During analysis of intraobserver similarities, the results of ICC calculation showed that reproducibility was good to excellent for all GRV calculation methods. The intraobserver reproducibility for Reader I was highest for cylinder and truncated cone formula and for Reader II for ellipsoid formula. The interobserver reproducibility was highest for ellipsoid formula. Regarding correlation between GRV and WL, significant negative correlation has been shown on the 12th month after LSG in %TWL and %EWL for every method of GRV calculation, most important for ellipsoid formula (%TWL - r(X,Y) = -0.335, p < 0.001 and %EWL - r(X,Y) = -0.373, p < 0.001). CONCLUSION: Radiographic methods of GRV calculation are characterized by good reproducibility and correlate with the postoperative WL.

RESUMO

In the XXI century obesity has become one of the most demanding epidemiological threats worldwide. At the same time, bariatric surgery has established itself as an effective treatment for morbidly obese patients, with laparoscopic sleeve gastrectomy (LSG) emerging as the most popular bariatric procedure. This paper reviews the role of imaging studies of patients after LSG. Computed tomography is widely considered as the method of choice in detection of complications in early postoperative period. The dynamic character of upper gastrointestinal examination allows for the assessment of passage through the gastric remnant. The paper also discusses evaluation of the shape and volume of the gastric remnant assessed by imaging studies.

RESUMO

The effects of weight loss following bariatric surgery on autonomic balance, arrhythmias and insulin resistance are still of interest. We prospectively investigated 50 patients with BMI > 40 kg/m2, aged 36.5 (18-56) years who underwent laparoscopic sleeve gastrectomy. Among other examinations, all subjects had 24-h Holter monitoring with heart rate variability (HRV) and heart rate turbulence (HRT) evaluation. After a median of 15 months, BMI decreased from 43.9 to 29.7 kg/m2, the incidence of hypertension decreased from 54 to 32% (p = 0.04) and any carbohydrate disorders decreased from 24 to 6% (p = 0.02). Fasting insulin concentration and insulin resistance index improved significantly (p < 0.001). Improvements in HRV parameters related to the sympathetic autonomic division were also observed (p < 0.001), while HRT evaluation was not conclusive. The enhancement of autonomic tone indices was correlated with reduction of BMI (SDNN-I r = 0.281 p = 0.04; SDNN r = 0.267 p = 0.05), but not with reduction of waist circumference, and it was also associated with decrease of mean heart rate (OR 0.02, 95%CI 0.0-0.1, p < 0.001). The incidence of arrhythmias was low and similar before and after follow-up. In conclusion, improvement of homeostasis of carbohydrate metabolism and autonomic function is observed in relatively young patients after weight loss due to laparoscopic sleeve gastrectomy.

RESUMO

Augmented reality (AR) delivers virtual information or some of its elements to the real world. This technology, which has been used primarily for entertainment and military applications, has vigorously entered medicine, especially in radiology and surgery, yet has never been used in organ transplantation. AR could be useful in training transplant surgeons, promoting organ donations, graft retrieval and allocation, and microscopic diagnosis of rejection, treatment of complications, and post-transplantation neoplasms. The availability of AR display tools such as Smartphone screens and head-mounted goggles, accessibility of software for automated image segmentation and 3-dimensional reconstruction, and algorithms allowing registration, make augmented reality an attractive tool for surgery including transplantation. The shortage of hospital IT specialists and insufficient investments from medical equipment manufacturers into the development of AR technology remain the most significant obstacles in its broader application.

RESUMO

INTRODUCTION: Increased values of emerging fat indices are correlated with increased cardiovascular risk. AIM: To examine the novel non-invasive predictors of coronary disease, namely the carotid extra-media thickness (EMT), PATIMA, and epicardial adipose tissue (EAT), in a group of patients with morbid obesity. MATERIAL AND METHODS: We examined a group of 40 morbidly obese (OB) patients and a control group (CG). All patients were subjected to anthropometric measurements, as well as laboratory and ultrasound examinations. RESULTS: EATmean and EMTmean differed significantly between groups (OB vs. CG): 5.09 vs. 3.50 and 808.50 vs. 737.00, p < 0.0001, respectively. CONCLUSIONS: Strong correlations were found between novel non-invasive predictors of coronary disease, namely the carotid extra-media thickness, PATIMA, and epicardial adipose tissue. The above-mentioned fat indices were not found to correlate significantly with BMI or other body weight-related parameters used to assess the adipose tissue content. Further studies are required.

RESUMO

BACKGROUND Controversy exists with regard to the effectiveness and reasons for bariatric procedures in patients older than 60 years. The goal of our study was to determine the reduction in risk of developing cardiovascular disease and type 2 diabetes mellitus after undergoing bariatric surgery in obese patients over age 60 at our institution. MATERIAL AND METHODS Patients with severe obesity (BMI >40 kg/m²) were retrospectively included in the study. Risk of cardiovascular disease and type 2 diabetes at baseline and their reduction during the follow-up period were evaluated with the following selected, currently preferred risk algorithms: (1) the Systemic Coronary Risk Evaluation (SCORE) scale; (2) the Framingham Risk Score (of myocardial infarction or coronary death) for patients with no prior history of diabetes, coronary heart disease, or intermittent claudication; and (3) the Framingham Offspring Diabetes Risk Score, which estimates the 8-year risk of developing type 2 diabetes. RESULTS All 33 elderly patients (32 women and 1 man, mean age 62.3±2.7 (BMI 44.3±6.2 kg/m²) significantly reduced their risk levels. We observed a decrease in the 10-year risk of a first fatal cardiovascular event (3.5±0.5 vs. 2.4±0.5, absolute risk reduction [ARR] 1.0); reduced 10-year risk of myocardial infarction or death (5.0±1.6 vs. 3.25±1.6, ARR 1.7); and reduced predicted 8-year risk of developing type 2 diabetes (7.4±7.2 vs. 3.1±0.3, ARR 4.3). No intra- or postoperative complications were observed. CONCLUSIONS Our study showed a significant reduction in risk of developing cardiovascular diseases and type 2 diabetes, as measured by available risk scores, in elderly patients undergoing bariatric procedures.
