Standardized acute care doctors training on the emerging pandemic of coronavirus pneumonia

The novel corona virus pneumonia epidemic poses a serious challenge to the medical and health systems of all nations in the world, especially discovering the severe shortage of intensive care medical professionals. Although our country’s intensive care medicine physicians have played a primary part in the combat against the epidemic, some problems have been debunked in the training of intensive care medicine personnel; equally there is inadequacy of standardized intensive care medicine training platform, and the lack of integrated training content and training format.
 Relatively single, insufficient preparations for responding to public health emergencies etc, Based on the actual experience of epidemic prevention and control and the treatment of critically ill patients, this article recommend that standardized training of resident physicians for critical care medicine should be carried out, the training content should be standardized, the combination of theory and clinical practice should be enhanced, the comprehensive quality of resident physicians should be improved, and the training methods should be expanded and strengthened. "Construction of a demand and capacity model for intensive care and hospital". These measures can make the critical care team become a professional team with a feel of social importance, which is of great acceptation for the long-term progress of critical care medicine, for the Nepalese medical system to easily respond to public health emergencies, and improve the comprehensive diagnosis and treatment capabilities of emergency and critical diseases. Excess deaths associated with COVID-19 are a direct result of the inadequate capacity of intensive care units and hospital beds.

The long-term effect of initial restoration intervention, landscape composition, and time on the progress of Pannonic sand grassland restoration

AbstractTo help upscale ecological restoration of degraded lands, landscape factors and longer time scales should be considered when assessing restoration efforts. We evaluated the impact of initial restoration intervention, landscape composition, and elapsed time since the restoration began on the long-term progress of Pannonic sand grassland restoration. Treatments (seeding, mowing, and carbon amendment) were implemented for 6–7 years and monitoring lasted up to 23 years after the first treatment applications in eight experimental blocks belonging to three field experiments. The abundance of target/neophyte species, and distance from primary grasslands and plantations (as major source of target/neophyte species) were estimated in 500 m landscape buffers around each block to characterize landscape composition. Restoration progress was calculated as the difference between the relative cover of target/neophyte species in treatment and control plots. Restoration intervention and neophyte abundance in the landscape had a significant effect on the restoration progress, but time did not. Seeding had the highest positive effect on target species and also prevented invasion by neophyte species. Higher abundance of neophytes in the landscape and the proximity to plantations increased the cover of neophytes in treatment plots. We conclude that restoration interventions may have a greater impact on restoration progress in the longer term than landscape factors or elapsed time. Seeding proved to be the best method in restoring sand grasslands by both favoring target species and controlling invasion. From the landscape factors, the abundance of neophyte species and distance to plantations should be considered when prioritizing areas and efforts for restoration.

Retinal layer thinning as a biomarker of long-term disability progression in multiple sclerosis

Background: Peripapillary retinal nerve fibre layer and macular ganglion cell plus inner plexiform layer thinning are markers of neuroaxonal degeneration in multiple sclerosis. Objective: We aimed to investigate the value of peripapillary retinal nerve fibre layer and ganglion cell plus inner plexiform layer thinning for prediction of long-term disability. Methods: This is a 6-year prospective longitudinal study on 93 multiple sclerosis patients. Optical coherence tomography scans were performed at baseline, after 1, 2 and 6 years. Primary endpoint was disability progression after 6 years, defined as expanded disability status scale worsening and/or cognitive deterioration. Univariate and multivariate analysis was used to investigate the value of peripapillary retinal nerve fibre layer and ganglion cell plus inner plexiform layer to predict the primary endpoint. Results: A total of 57 (61.3%) patients had disability worsening, 40 (43.0%) expanded disability status scale worsening and 34 (36.6%) cognitive deterioration. Mean peripapillary retinal nerve fibre layer and ganglion cell plus inner plexiform layer baseline thickness were 93.0 and 75.2 µm, and mean annualised peripapillary retinal nerve fibre layer and ganglion cell plus inner plexiform layer thinning rates over 6 years were 1.3 and 1.6 µm, respectively. Univariate and multivariate analysis revealed lower peripapillary retinal nerve fibre layer and ganglion cell plus inner plexiform layer baseline thickness and higher annualised thinning rates in patients with disability progression after 6 years. Effects were more pronounced for ganglion cell plus inner plexiform layer and expanded disability status scale worsening than for peripapillary retinal nerve fibre layer models and cognitive deterioration. Conclusion: Ganglion cell plus inner plexiform layer and peripapillary retinal nerve fibre layer measurements depict neurodegeneration and predict disability progression in multiple sclerosis.

Endogenous clues promoting remyelination in multiple sclerosis.

The introduction some 30 years ago of β-interferon, followed by a panel of immunomodulators and immunosuppressants has led to a remarkable improvement in the management of multiple sclerosis (MS) patients. Despite these noticeable progresses, which lower the number of relapses and thereby ameliorate patients' quality of life, preventing long-term progression of disability is still an unmet need, highlighting the necessity to develop therapeutic strategies aimed at repairing demyelinated lesions and protecting axons from degeneration. The capacity of human brain to self-regenerate demyelinated lesion has opened a field of research aimed at fostering this endogenous potential. The pioneer electron microscopic evidence by Périer and Grégoire [Périer O, Grégoire A. Electron microscopic features of multiple sclerosis lesions. Brain 1965; 88:937-952] suggesting the capacity of human brain to self-regenerate demyelinated lesion has opened a field of research aimed at fostering this endogenous potential. Here we review some recently identified mechanisms involved in the remyelination process, focusing on the role of electrical activity and the involvement of innate immune cells. We then provide an update on current strategies promoting endogenous myelin repair. Identification of therapeutic targets for remyelination has opened an active therapeutic field in MS. Although still in early phase trials, with heterogenous efficacy, the door for myelin regeneration in MS is now opened.

Novel Biomarkers of Kidney Disease in Advanced Heart Failure: Beyond GFR and Proteinuria.

Kidney disease is a common finding in patients with heart failure and can significantly impact treatment decisions and outcomes. Abnormal kidney function is currently determined in clinical practice using filtration markers in the blood to estimate glomerular filtration rate, but the manifestations of kidney disease in the setting of heart failure are much more complex than this. In this manuscript, we review novel biomarkers that may provide a more well-rounded assessment of kidney disease in patients with heart failure. Galectin-3, ST2, FGF-23, suPAR, miRNA, GDF-15, and NAG may be prognostic of kidney disease progression. L-FABP and suPAR may help predict acute kidney injury (AKI). ST2 and NAG may be helpful in diuretic resistance. Several biomarkers may be useful in determining prognosis of long-term kidney disease progression, prediction of AKI, and development of diuretic resistance. Further research into the mechanisms of kidney disease in heart failure utilizing many of these biomarkers may lead to the identification of therapeutic targets.

Is the Paris rulebook sufficient for effective implementation of Paris Agreement?

Glasgow Climate Conference concluded the negotiation on implementing rules for Paris Agreement and adopted the Glasgow Climate Pact. Based on practices under the UNFCCC and its Kyoto Protocol, Paris Agreement enhanced global climate change governance. Paris Agreement established a system centered around ‘nationally determined contributions’ (NDCs) of Parties, with a transparency framework to ensure information flow running the system, meanwhile facilitating implementation by Parties through the mechanism on facilitation and compliance, as well as urging Parties to enhance ambition both at individual level and aggregate level through the mechanism on Global Stocktake. By doing so, it is logical that the system would lead to the achievement of the goal set by Paris Agreement. However, the system still faces significant deficiency, such as lack of information timeliness, intransparency of some necessary information, hypothesis-based but not solution-based decision-making, and lack of effective assurance for developing countries to get finance and technology support. It is concluded that this system is beneficial to long-term climate change policy decision and tracking progress of actions, while for short-term decision-making, more comprehensive consideration is needed than only based on the mechanisms of and outcomes from the system. International society should pay more attention to the progress of implementation, as well as ambition of various support provided to developing countries, than only the ambition of mitigation target numbers.

Long-term clinical course and progression of lymphangioleiomyomatosis in a single lung transplant referral centre in Korea

We aimed to describe the clinical features of lymphangioleiomyomatosis (LAM) in Korean patients and identify factors associated with progressive disease (PD). Clinical features of 54 patients with definite or probable LAM from 2005 to 2018 were retrospectively analysed. Common features were pneumothorax (66.7%) and abdominal lymphadenopathy (50.0%). Twenty-three (42.6%) patients were initially treated with mechanistic target of rapamycin (mTOR) inhibitors. Lung transplantation (LT) was performed in 13 (24.1%) patients. Grouped based on the annual decline in forced expiratory volume in 1 s (FEV1) from baseline and LT, 36 (66.7%) patients exhibited stable disease (SD). All six deaths (11.1%) occurred in PD. Proportion of SD was higher in those treated initially with mTOR inhibitors than in those under observation (p = 0.043). Univariate analysis revealed sirolimus use, and baseline forced vital capacity, FEV1, and diffusing capacity of the lungs for carbon monoxide are associated with PD. Multivariate analysis showed that only sirolimus use (odds ratio 0.141, 95% confidence interval 0.021–0.949, p = 0.044) reduced PD. Kaplan–Meier analysis estimates overall survival of 92.0% and 74.7% at 5 and 10 years, respectively. A considerable proportion of LAM patients remain clinically stable without treatment. LT is an increasingly viable option for patients with severe lung function decline.

Crosstalk Between Autophagy and Innate Immunity: A Pivotal Role in Hepatic Fibrosis.

Liver fibrosis is a repair process of chronic liver injuries induced by toxic substances, pathogens, and inflammation, which exhibits a feature such as deposition of the extracellular matrix. The initiation and progression of liver fibrosis heavily relies on excessive activation of hepatic stellate cells (HSCs). The activated HSCs express different kinds of chemokine receptors to further promote matrix remodulation. The long-term progression of liver fibrosis will contribute to dysfunction of the liver and ultimately cause hepatocellular carcinoma. The liver also has abundant innate immune cells, including DCs, NK cells, NKT cells, neutrophils, and Kupffer cells, which conduct complicated functions to activation and expansion of HSCs and liver fibrosis. Autophagy is one specific type of cell death, by which the aberrantly expressed protein and damaged organelles are transferred to lysosomes for further degradation, playing a crucial role in cellular homeostasis. Autophagy is also important to innate immune cells in various aspects. The previous studies have shown that dysfunction of autophagy in hepatic immune cells can result in the initiation and progression of inflammation in the liver, directly or indirectly causing activation of HSCs, which ultimately accelerate liver fibrosis. Given the crosstalk between innate immune cells, autophagy, and fibrosis progression is complicated, and the therapeutic options for liver fibrosis are quite limited, the exploration is essential. Herein, we review the previous studies about the influence of autophagy and innate immunity on liver fibrosis and the molecular mechanism to provide novel insight into the prevention and treatment of liver fibrosis.

Ten-year Results after Conventional Corneal Cross-linking in Korean Patients with Progressive Keratoconus

Purpose: To evaluate the long-term effects of conventional corneal cross-linking in patients with progressive keratoconus.Methods: A total of 18 eyes of 9 patients diagnosed with keratoconus were analyzed retrospectively. One eye was diagnosed with progressive keratoconus and conventional corneal crosslinking was performed. The other eye was classified as non-progressive and remained untreated. All patients were assessed with best corrected visual acuity (BCVA), maximum keratometry (Kmax), mean keratometry (Kmean), corneal astigmatism, and corneal thickness. Clinical data were collected before the procedure and at 1, 3, 6 months and 1 to 10 years after the procedure.Results: The BCVA significantly improved from 0.63 ± 0.18 logarithm of the minimum angle of resolution (logMAR) to 0.46 ± 0.25 logMAR at 10 years after conventional corneal crosslinking (p = 0.027). The Kmax and Kmean decreased from 65.90 ± 9.43 D and 52.82 ± 5.16 D to 62.83 ± 8.16 D and 51.52 ± 5.18 D, respectively (p = 0.021, p = 0.028, respectively). Corneal astigmatism decreased from 6.97 ± 2.21 D to 5.53 ± 1.64 D (p = 0.008). The thinnest corneal thickness decreased from 435.11 ± 53.37 μm to 369.22 ± 64.00 μm 1 month after the procedure (p = 0.008), and gradually improved over time. At 10 years, the thinnest corneal thickness increased to 410.11 ± 61.32 μm (p = 0.097). In the untreated eyes, the mean keratometry significantly increased after 4 years of follow-up, but other factors did not change significantly. Although corneal opacity persisted for up to 10 years in 3 eyes of the treatment group, there was no significant difference of BCVA compared to the treated eyes without corneal opacity (p = 0.714).Conclusions: In patients with progressive keratoconus, conventional corneal crosslinking is a safe and effective procedure that suppresses long-term progression.

Transient versus persistent improved ejection fraction in non-ischaemic dilated cardiomyopathy.

The recent definition of heart failure with improved ejection fraction outlined the importance of the longitudinal assessment of left ventricular ejection fraction (LVEF). However, long-term progression and outcomes of this subgroup are poorly explored. We sought to assess the LVEF trajectories and their correlations with outcome in non-ischaemic dilated cardiomyopathy (NICM) with improved ejection fraction (impEF). Consecutive NICM patients with baseline LVEF ≤40% enrolled in the Trieste Heart Muscle Disease Registry with ≥1 LVEF assessment after baseline were included. ImpEF was defined as a baseline LVEF ≤40%, and second evaluation showing both a ≥10% point increase from baseline LVEF and LVEF >40%. Transient impEF was defined by the documentation of recurrent LVEF ≤40% during follow-up. The primary endpoint was a composite of all-cause death, heart transplantation and left ventricular assist device (D/HT/LVAD). Among 800 patients, 460 (57%) had impEF (median time to improvement 13 months). Transient impEF was observed in 189 patients (41% of the overall impEF group) and was associated with higher risk of D/HT/LVAD compared with persistent impEF at multivariable analysis (hazard ratio 2.54; 95% confidence interval 1.60-4.04). The association of declining LVEF with the risk of D/HT/LVAD was non-linear, with a steep increase up to 8% points reduction, then remaining stable. In NICM, a 57% rate of impEF was observed. However, recurrent decline in LVEF was observed in ≈40% of impEF patients and it was associated with an increased risk of D/HT/LVAD.

Recognition of the Effect of Indirect Revascularization for Moyamoya Disease: The Balance Between the Stage Progression and Neoangiogenesis.

ObjectiveTo explore the long-term progression of neoangiogenesis after indirect revascularization for moyamoya disease (MMD).MethodsWe enrolled patients who were diagnosed with MMD and treated by encephaloduroarteriosynangiosis (EDAS) surgery at our center from December 2002 through September 2009. A comparative study between short-term (6–12 months) and long-term (duration ≥ 8 years) follow-up angiographies was performed. The development of collateral circulation through EDAS was graded according to the system described by the Matsushima grade system.ResultsA total of 78 patients who received indirect EDAS were enrolled in the study. The mean age at the first operation was 26.9 ± 15.0 years. The Matsushima grades of the same hemisphere were higher at the long-term follow-up compared with the short-term follow-up. Importantly, no attenuation was observed in any hemisphere during the long-term follow-up. In total, 51 hemispheres (32.7%) and 26 hemispheres (16.6%) had progression during the short-term and the long-term follow-up, respectively. The ipsilateral Suzuki stage showed a significant negative correlation with progression pace. Furthermore, higher Suzuki stages were significantly correlated with the postsurgical Matsushima grade at both time points. A total of nine strokes (11.5%) occurred in 78 patients was reported at the long-term follow-up. The annual incidence rate of recurrent strokes was higher for the stage progression group than for the stable group.ConclusionFor patients with MMD, postsurgical neoangiogenesis after indirect bypass continuously improved with time. The short-term progression of the internal carotid artery (ICA) might be attributed to cerebral revascularization, while the long-term progression should be attributed to the natural progression of the disease.

Clinical outcomes of a large cohort of individuals with the F508del/5T;TG12 CFTR genotype

BackgroundIn recent years, patients with cystic fibrosis (CF) conductance regulator (CFTR) variant poly(T) sequences have been increasingly reported with a wide spectrum of clinical severity. We describe the long-term clinical outcomes and progression to a CF diagnosis over time in a large Italian cohort of patients carrying the CFTR F508del/5T;TG12 genotype. MethodsA retrospective analysis of subjects from 10 CF centres in Italy with the F508del/5T;TG12 genotype was performed. Demographic, clinical, microbiological, and biochemical data, as well as information about the follow-ups and complications of the enroled patients, were collected. ResultsA total of 129 subjects (54 females; median age: 15.0 years, range: 0–58 years; 59 older than 18 years) were included. In terms of initial diagnoses, 30 were CF (23.3%), 41 were CFTR-related disorder (CFTR-RD) (31.7%), and 58 were CF transmembrane conductance regulator-related metabolic syndrome/cystic fibrosis screen positive, inconclusive diagnosis (CRMS/CFSPID) (45.0%). After a median follow-up of 6.7 years (range 0.2–25 years), 15 patients progressed to CF, bringing the total number of CF diagnoses to 45/129 (34.9%). Most of these patients had mild lung diseases with pancreatic sufficiency and a low prevalence of CF-related complications. ConclusionsAt the end of the study, 34.9% of subjects with the CFTR F508del/5T;TG12 genotype were diagnosed with CF. We suggest including patients with the F508del/5T;TG12 genotype in long-term follow-ups.

MO442: COVID-19 Disease Severity and Risk of 12-Month CKD Progression

Abstract BACKGROUND AND AIMS Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection has been in our daily practice for almost 2 years now. Since the beginning of the pandemic, we have aimed to study its most immediate effects on patients to find the best line of treatment or, at least, mitigate its worst outcomes. Nevertheless, we also know some long-term health consequences such as fatigue, sleep difficulties, headache, among others, but its long-term kidney effects are not entirely clear yet. The aim of this study was to describe if coronavirus disease's (COVID-19) severity increases the risk of chronic kidney disease (CKD) progression after a previous hospitalization and observe if there are any additional risk factors that could help us predict this outcome. METHOD In this study, a sample of consecutive patients who required admission due to COVID-19 during the first wave of the pandemic (from March to May of 2020) was recruited. Patients were followed for 12 months since initial admission. The composite outcome of the study included either death or CKD progression. CKD progression was defined as incremental progression to a higher KDIGO CKD stage compared to baseline pre COVID-19 renal function [(in mL/min/1.73 m2): estimated glomerular filtration rate (eGFR) ≥60; stage 3a: 45–59; stage 3b: 30–44; stage 4: 15–29; stage 5: <15], or dialysis initiation. Cardiovascular disease was defined as a history of myocardial infarction, stroke, or peripheral vascular disease. Chronic lung diseases included asthma, chronic obstructive pulmonary disease and chronic bronchitis. RESULTS The sample was composed of 93 patients, of which 14 (15.1%) died during follow-up. Of those alive 12 months after initial admission, 17 (21.5%) suffered CKD progression. No patient required renal replacement therapy. Patients that suffered the composite outcome presented a higher prevalence of cancer, tended to be slightly older and suffered from additional comorbidities more frequently (Table). In multivariate logistic regression analysis, previous history of CKD [odds ratio (OR): 1.066 (0.433–2.624); P = 0.889], severe or critical COVID-19 on admission [OR: 0.657 (0.24–1.8); P =0.414] or ICU admission [OR: 0.986 (0.082–11.898); P = 0.991] failed to predict the composite outcome. CONCLUSION Our main hypothesis was that COVID-19 sequelae should be due to an exaggerated activation of the immune system against the virus. Thus, patients that suffered severe COVID-19 should be expected to develop more long-term health consequences of the infection when compared with those with milder disease. However, we failed to prove any link between COVID-19 severity and long-term CKD progression. History of CKD or ICU admission was also unable to predict the composite outcome. Previous studies have described a relationship between COVID-19 severity and adverse renal outcomes, a relationship that we failed to observe. These discrepancies could be due to the small sample size of our study and the different definition of CKD progression applied. In addition, age could act as a potential modifier of CKD progression after admission due to COVID. More studies are required to further clarify the mechanisms and long-term renal consequences of COVID-19 and define potential lines of treatment.

Bile Acids Metabolites as Predictors of long-term Multiple Sclerosis Progression (S5.004)

Bile Acids Metabolites as Predictors of long-term Multiple Sclerosis Progression (S5.004)

May Coronary Artery Bypass Grafting Affect Native Coronary Atherosclerosis progression?

Background: Coronary artery bypass grafting (CABG) continues to be the best standard in the management of severe coronary artery disease (CAD), providing good symptom management and life extension. Although CABG was first performed by reversed saphenous veins (SVGs), surgeons have increasingly adopted arterial conduits because of their longer-term patency and resistance to atherosclerosis. CABG's efficacy may potentially be affected by the extension of atherosclerosis in the native coronary arteries. Few researches have investigated the long-term angiographic disease progression of native coronary arteries after surgical revascularization, or the variables that may impact this progression. Proximal native disease progression was presented to be two to six times more common than distal disease progression, with greater rates of progression in coronaries bypassed by SVGs than arterial grafts. The goal of this research was to determine influence of CABG on the extension of native coronaries atherosclerosis.
 Methods: This prospective study was established on 25 patients who were diagnosed to have ischemic heart disease in cardiothoracic surgery department in Faculty of Medicine Menoufia University.
 Results: The study showed that according to the risk factors among the studied cases, smoking was (60%), Dyslipidemia was (32%), HTN was (32%) and Diabetes was (32). According to grafts in proximal lesions, there was progression of atherosclerosis up to total occlusion, but in Distal lesions, there was significant regression of atherosclerosis. As result, there was statistically significant difference between proximal with distal lesions. Also, study showed that there was a significant difference between left system (LAD, D, OM) in comparison with right system (PDA) regarding distal lesion. Our results showed that univariate logistic regression analysis for progression in distal lesion regarding Dyslipidemia and Diabetes.
 Conclusion: Progression of disease is more evident in coronary segment proximal to anastomosis, while regression of disease is more evident in coronary segment distal to anastomosis with statistically significant difference between them, also the risk of disease progression post CABG was found to be multifactorial, as certain risk factors can affect progression of the disease as Diabetes mellitus and dyslipidemia that were of statistically significance.

Comprehensive Evaluation of Long-term Dynamic Mechanical Behavior in a Rat MIA OA Model

Osteoarthritis (OA) is highly prevalent across the world with 30% of the US population who are 45 and older estimated to have knee osteoarthritis. The primary clinical indication of OA is pain. Mono-iodo acetate (MIA) induced osteoarthritis is commonly used to study pain in pre-clinical models. Currently mechanical allodynia and thermal hyperalgesia are used to measure the pain outcomes in most pre-clinical models however, the non-evoked dynamic weight bearing analysis provides more clinically relevant behavioral assessment of pain. The goal of the study is to comprehensively understand the changes in dynamic weight bearing behavior of rats with MIA induced OA over a period of 16 weeks. Osteoarthritis was induced in female Sprague-Dawley rats by C-arm guided injections of MIA (3 mg) into the intra-articular region of the right knee. Non-evoked dynamic weight bearing was evaluated using a pressure sensor system (Bioseb DWB 2.0), mechanical allodynia using Von Frey filaments, and transcriptional changes at the dorsal root ganglion using BioRad gene array. MIA model showed mechanical allodynia of the ipsilateral paw for over 3 months. The dynamic weight bearing parameters reveal continuous compensatory weight preference towards the uninjured limbs for the same period. Unlike Von Frey, significantly different dynamic behavioral parameters begin to appear within 24 hours post MIA injection. Moreover, parameters related to weight and area distribution showed temporal changes over the course of the study. The study shows that dynamic weight bearing assessment is an effective tool to understand the long-term progression of pain behavior in a MIA model. Grant support from NIH R01AR075143.

AP-517-01 THE LIKELIHOOD OF CLINICALLY SIGNIFICANT QTC PROLONGATION DURING LONG-TERM FOLLOW UP IN PATIENTS WITH CONCEALED LONG QT SYNDROME AND NORMAL QTC AT INITIAL PRESENTATION

Patients carrying genetic variants associated with long QT syndrome (LQTS) who initially present with normal QTc is a large and growing group of patients who are commonly diagnosed during genetic cascade family screening. Long-term progression of QTc interval in this patient group remains poorly described.

Persistent lipedema pain in patients after bariatric surgery: a case series of 13 patients.

Lipedema often remains undiagnosed in patients with obesity, leading to mismanagement of treatment. Because of this, despite remarkable weight loss after bariatric surgery and decreases in hip and abdomen circumference, some patients show only small decreases in circumference of the extremities and report persistent limb pain. The goal of this work is to raise awareness of lipedema coincident with obesity, mistakenly diagnosed as obesity alone, in order to ensure the correct diagnosis of the condition and to achieve better treatment outcomes for people with lipedema and coincident obesity. CG Lympha Clinic, Cologne, and Ernst von Bergmann Clinic, Potsdam. From clinical records, we identified 13 patients who were diagnosed with lipedema only after undergoing bariatric surgery. We describe the course of their pain before and after bariatric surgery, focusing on the long-term progression of symptoms accompanying the disease. Lipedema cannot be cured by bariatric surgery, and although the patients in this study lost an average of more than 50 kg of weight, they displayed no improvement in the pain symptoms typical of lipedema. Because of the different etiologies of lipedema and obesity, lipedema requires its own specific treatment. Patients suffering from obesity should always be assessed for pain and lipedema. If coincident lipedema is diagnosed, we suggest that bariatric surgery only be performed first if diet and exercise have failed, the patient's body mass index is >40 kg/m2, and the patient has been informed of the possible persistence of pain. Lipedema, like a coincident disease, must be additionally treated conservatively or preferably surgically. This optimized treatment may help to better manage patient expectations after weight loss.
