Obesity is becoming more and more prevalent especially in Western industrial nations. The understanding of adipose tissue as an endocrine organ as well as the detection of adipocytokines - hormones that are secreted from the adipose tissue - gave reason to examine the interactions between adipose tissue and target organs. These efforts have been intensified especially in the context of bariatric surgery as promising weight loss therapy. Interactions between the lung and adipose tissue have rarely been investigated and are not well understood. There are obvious mechanical effects of obesity on lung function explaining the associations between obesity and lung diseases, in particular obesity hypoventilation syndrome, obstructive sleep apnea syndrome, asthma, and chronic obstructive pulmonary disease. The rise in the prevalence of obesity affects the epidemiology of pulmonary diseases as well. The aim of this review is to summarize the current knowledge on interactions, associations, and consequences of obesity and weight loss on lung function and lung diseases. Based on these data, areas for future research are identified.We report a case of graft intolerance syndrome in which transplant nephrectomy was performed 11 years after kidney transplantation. A 46-year-old man was admitted to our hospital in February 2018 with a mild fever, left lower abdominal pain, and gross hematuria with enlargement of the transplanted kidney. Urinary tract infection was ruled out. Estrone research buy Because the symptoms developed after the immunosuppressants had been stopped after kidney graft loss, graft intolerance syndrome was suspected. He had lost his graft in 2016 and had stopped all immunosuppressants since January of 2017. Immunosuppressive therapy was intensified, and steroid half-pulse therapy was added for 3 days. After the steroid pulse therapy, the C-reactive protein (CRP) decreased from 6.47 mg/dL to 0.76 mg/dL, but there was little improvement in the symptoms, and the CRP then increased to 4.44 mg/dL. Transplant nephrectomy was performed in March 2018. Postoperatively, the symptoms disappeared without the administration of immunosuppressants, and the CRP decreased. Pathologically, the resected kidney graft showed persistent active allograft rejection with severe endarteritis, transplant glomerulopathy, and diffuse interstitial fibrosis. Massive thrombi occluded the large arteries, and there was extensive hemorrhagic cortical necrosis. Transplant nephrectomy is uncommon in patients >6 months after transplantation. However, even if more time has passed since transplantation, as in this case, transplant nephrectomy may be a valid option in some cases of severe graft intolerance syndrome.

To date, sepsis remains one of the main challenges of intensive care in pediatrics. Newborns with low birth weight and infants with chronic diseases and congenital disorders are particularly at risk. The incidence of infectious complications in pediatric cardiac surgery is known to be approximately 15-30%. The main etiological factor of sepsis is endotoxin.

To evaluate the efficiency and safety of polymyxin (PMX) B-immobilized column-direct hemoperfusion in complex intensive therapy of sepsis in children after cardiac surgery with cardiopulmonary bypass.

Prospective cohort study.

This study enrolled 15 children, aged 9-96 months, with congenital heart diseases and with body weights of 6.2-22.5 kg. The criteria for admission were body weight >6 kg and clinical and laboratory signs of sepsis (microbiological analysis, procalcitonin [PCT] >2 ng/mL, and endotoxin activity assay [ЕАА] >0.6). Intensive care included inotropic and vasopressor support, mechanical ventilation, broad-spectrum antibiotihemodynamic parameters, oxygenation index, and laboratory signs of sepsis, with decreases in the endotoxin concentration according to the EAA, PCT, and presepsin levels. The 28-day survival of the patients in this severely affected group was 80%. Main Conclusion The inclusion of extracorporeal methods of blood purification, aimed at the selective elimination of circulating endotoxin, in the treatment of sepsis increases the survival rates of children after open heart surgery. Second Conclusion The obtained results of sepsis therapy with PMX hemoperfusion in children after cardiac surgery enable us to suggest the sufficient safety and efficiency of the procedures in this category of severely affected patients.

High expression of leucine-rich alpha-2-glycoprotein 1 (LRG1) is closely related to angiogenesis, which may play an important role in promoting invasion and metastasis. However, the current literature has yet to clarify the clinical significance of LRG1 in breast cancer.

The purpose of this work was to validate the correlation between LRG1 expression and prognosis in early breast cancer.

We utilized an LRG1 detection agent in 330 cases of early breast cancer. The correlation of LRG1 expression with clinicopathological features, patient recurrence, and survival was investigated.

Compared with adjacent tissue samples, an elevated expression of LRG1 was observed in breast cancer samples. Moreover, LRG1 expression is associated with the number of lymphatic metastases and TNM pathological stage (p = 0.000, p = 0.000, respectively). For disease-free survival (DFS), the Kaplan-Meier curve indicated a poorer prognosis for the group with high LRG1 levels compared with the low LRG1 group (p = 0.000). A similar result was found for overall survival (OS; p = 0.000). The multivariate Cox regression indicated that LRG1 was still associated with DFS (HR 2.090, 95% CI 1.205-3.625, p = 0.009) and OS (HR 2.112, 95% CI 1.167-3.822, p = 0.013). The histological grade, TNM pathological stage, and molecular subtype were identified as independent risk factors affecting OS.

In the malignant progression of breast cancer, high LRG1 levels are associated with lymphatic metastasis, histological grade, poor DFS, and poor OS. This study validates the use of LRG1 as a potential prognosis biomarker for early breast cancer.

Little is known about its clinical relevance, and inconsistencies in medical and surgical management remain among different settings. In this paper, we systematically reviewed the published cases of the IERA in terms of clinical presentation, diagnosis, and management. A total of 153 cases of IERA were covered. Arrhythmia, dyspnea, and palpitation were found to be the most common clinical manifestations. It tends to be associated with life-threatening complications and sudden cardiac death. Diagnosis was mostly established by using echocardiography. Presenting symptoms, abnormal ECG findings, and therapeutic modalities were significantly related to the prognosis of IERA. Symptomatic patients were significantly more likely to have poor outcomes than asymptomatic patients (p = 0.044), and conservative treatment was more associated with adverse outcomes compared to surgical resection (p = 0.016). In conclusion, IERA, although rare, tends to be associated with potential life-threatening complications and sudden cardiac death. Echocardiography is the most common diagnostic modality. Surgical resection is indicated for symptomatic patients.The COVID-19 outbreak is a global public health issue, having profound effects on most aspects of societal well-being, including physical and mental health. A plethora of studies, globally, have suggested the existence of a sex disparity in the outcome of COVID-19 patients, that is mainly due to mechanisms of viral infection, immune response to the virus, development of a hyperinflammation, and development of systemic complications, particularly thromboembolism. These differences appear to be more pronounced in elderly COVID-19 patients. Epidemiological data report a sex difference in the severity and outcome of COVID-19 disease with a more favourable course of the disease in women compared to men, regardless of age range although the rate of SARS-CoV-2 infection seems to be similar in both sexes. Sex hormones, including androgens and estrogens, may not only impact viral entry and load, but also shape the clinical manifestations, complications and, ultimately, the outcome of COVID-19 disease. The current reviollowing SARS-CoV-2 infection is even more palpable, as elderly men appear more prone to severe COVID-19 because of a greater predisposition to infections, a weaker immune defence and an enhanced thrombotic state compared to women. The review highlights potential novel therapeutic approaches employing the administration of hormonal or anti-hormonal therapy in combination with antiviral drugs in COVID-19 patients.Primary central nervous system lymphoma is a rare aggressive disease that largely affects elderly patients and is associated with poor prognosis. The optimal treatment approach is not yet defined and it consists of induction and consolidation phases. The combination of high-dose (HD) methotrexate-based chemotherapy followed by whole-brain radiotherapy (WBRT) prolongs the median progression-free survival (PFS) and overall survival 2- to 3-fold as compared to WBRT alone but is associated with significant delayed neurotoxicity. Alternative strategies are being investigated in order to improve disease outcomes and spare patients the neurocognitive side effects. These include reduced-dose WBRT, non-myeloablative HD chemotherapy, or HD chemotherapy with autologous stem cell transplantation (HDC/ASCT). There are no randomized studies that compare all these consolidation regimens head to head but recently HDC/ASCT has been evaluated versus WBRT in prospective randomized studies. These studies proved that WBRT and HDC/ASCT yield similar 2-year PFS with preserved or improved cognitive function after HDC/ASCT. Yet, the proportion of patients treated with such intensive consolidation is low, both in real life and in specialized centers, leaving many unsettled issues. This review is appraising current dilemmas related to the choice of consolidating therapeutic modalities, their associated acute and delayed toxicity, and future prospects for alternative approaches in the elderly.

To assess whether biopsy of multiparametric magnetic resonance imaging (MRI)-negative lobes can be avoided without compromising significant cancer (SC) detection among men with unilateral MRI-positive lobes.

From April 2013 to April 2019, 322 men with elevated prostate-specific antigen (PSA <20 ng/mL) and unilateral MRI-positive lobes underwent targeted 4-core and systematic 14-core biopsy. MRI findings were prospectively collected and evaluated according to the Prostate Imaging-Reporting and Data System (PI-RADS) version 2, and scores ≥3 were considered positive. SC was defined as Gleason score ≥3 + 4 or maximal cancer length ≥5 mm. We developed predictive models of overall cancer and SC in MRI-negative lobes and evaluated the performance of these models.

Detection rates of overall cancer/SC were 69%/61% for the overall cohort, 58%/48% for MRI-positive lobes, and 36%/20% for MRI-negative lobes. Age ≥75 years, PSA density ≥0.3, and PI-RADS ≥4 were independently predictive of both overall cancer and SC in MRI-negative lobes; 1 point was assigned for each risk factor, and the predictive score was defined as the sum of points (0-3) for both overall cancer and SC.
