Cooperative Mercury Motion in the Ionic Conductor Cu2HgI4

We present the observation of glasslike dynamic correlations of mobile mercury ions in the ionic conductor Cu_2HgI_4, detected in both NMR and nonlinear conductivity experiments. The results show that dynamic cooperativity appears in systems seemingly unrelated to glassy and soft arrested materials. A simple kinetic two-component model is proposed, which seems to provide a good description of the cooperative ionic dynamics

Mnenje za spremljanje bolnikov po preboleli covidni pljučnici

Pljučnica je najpogostejši vzrok za težji potek okužbe z virusom SARS-CoV-2 in s hospitalizacijo. Potek covidne pljučnice je lahko različen; infiltrati, vidni na rentgenski sliki, se lahko resorbirajo spontano, včasih pa je potrebno zdravljenje s sistemskimi glukokortikoidi. Ob odpustu iz bolnišnice zdravljenje običajno še ni končano, zato je Združenje pulmologov Slovenije v želji po enotnem obravnavanju bolnikov s covidno pljučnico izdelalo mnenje za obravnavo in sledenje bolnikov po odpustu iz bolnišnice. Zavedamo se, da ob novi bolezni ne gre za dokončno mnenje, saj bodo nova spoznanja o covidni pljučnici zanesljivo zahtevala obnavljanje mnenj

Idiopathic pulmonary fibrosis in patients with early-stage non-small-cell lung cancer after surgical resection

Background. The outcomes of patients with both lung cancer and idiopathic pulmonary fibrosis (IPF) are unfavorable. Therapeutic interventions for lung cancer such as surgery can cause acute exacerbation of IPF (aeIPF). This study aimed to assess the frequency of IPF in a group of patients with early-stage non-small-cell lung cancer (NSCLC) and to report clinical characteristics and outcomes of this cohort of patients. Patients and methods. This observational cohort retrospective study analyzed 641 pathological records of patients after surgical resection of early-stage non-small-cell lung cancer (NSCLC) at University Clinic Golnik from May 2010 to April 2017. Pathological records of NSCLC with coexisting IPF were reviewed. CT scans and biopsy specimens for this group of patients were analyzed by a thoracic radiologist and pathologist, independently. We searched radiological and pathological features of usual interstitial pneumonia (UIP) pattern in this group of patients. We report the clinical characteristics and outcome of this cohort of patients. Results. Out of 641 patients with early-stage NSCLC, only 13 (2.0%) had histologically and radiologically proven coexisting UIP/IPF. Squamous cell carcinoma was the most common type of lung cancer (7/13 patients). The majority of tumors were small size (all being pT1 or pT2), stage I–II (11/13 patients), located in the lower lung lobes (11/13 patients). Almost all patients were current or ex-smokers (11/13 patients). There were two pathologically confirmed fatal cases (15.4%) due to aeIPF in the first two months after radical treatment, one after adjuvant radiotherapy and the other after surgery. Out of 13 patients, one patient had a lung cancer relapse. Conclusions. Frequency of UIP/IPF in surgically treated early stage NSCLC is rather low. Our observational study shows that radical treatment of lung cancer can cause aeIPF with dismal outcome in this group of patients. The standard of care in these mostly elderly patients still remains unresolved

Genomic Confirmation of the P-IIIe Subclass of Snake Venom Metalloproteinases and Characterisation of Its First Member, a Disintegrin-Like/Cysteine-Rich Protein

Disintegrin-like/cysteine-rich (DC) proteins have long been regarded just as products of proteolysis of P-III snake venom metalloproteinases (SVMPs). However, here we demonstrate that a DC protein from the venom of Vipera ammodytes (Vaa; nose-horned viper), VaaMPIII-3, is encoded per se by a P-III SVMP-like gene that has a deletion in the region of the catalytic metalloproteinase domain and in part of the non-catalytic disintegrin-like domain. In this way, we justify the proposal of the introduction of a new subclass P-IIIe of SVMP-derived DC proteins. We purified VaaMPIII-3 from the venom of Vaa in a series of chromatographic steps. A covalent chromatography step based on thiol-disulphide exchange revealed that VaaMPIII-3 contains an unpaired Cys residue. This was demonstrated to be Cys6 in about 90% and Cys19 in about 10% of the VaaMPIII-3 molecules. We further constructed a three-dimensional homology model of VaaMPIII-3. From this model, it is evident that both Cys6 and Cys19 can pair with Cys26, which suggests that the intramolecular thiol-disulphide exchange has a regulatory function. VaaMPIII-3 is an acidic 21-kDa monomeric glycoprotein that exists in at least six N-glycoforms, with isoelectric points ranging from pH 4.5 to 5.1. Consistent with the presence of an integrin-binding motif in its sequence, SECD, VaaMPIII-3 inhibited collagen-induced platelet aggregation. It also inhibited ADP- and arachidonic-acid-induced platelet aggregation, but not ristocetin-induced platelet agglutination and the blood coagulation cascade

Covid 19 - pneumonia is a serious illness and can lead to respiratory failure. Pulmonary infiltrates often resorb spontaneouslyhowever, sometimes treatment with systemic glucocorticoids is required. Upon discharge from the hospital, treatment is usually not yet completed. The Slovenian Respiratory society made suggestions for the treatment and follow-up of patients with covid 19 pneumonia after discharge from hospital. We are aware that with new findings we will need to update these recommendations

Recommendations for diagnosis and treatment of patients with lung cancer

In 2019, the Recommendations for the management of patients with lung cancer were published bringing much-needed standardisation of diagnosis and treatment to improve survival of patients with lung cancer. Three years after the original Recommendations were published, the update of the Recommendations brings the most innovations in the chapter on systemic treatment of patients with lung cancer. This reflects the remarkable progress made in the field of understanding the oncogenesis and biology of lung cancer and thus the development of new drugs. The burden of lung cancer remains high, as lung cancer is still the most common cause of cancer related death in our country and worldwide. Lung cancer is responsible for one of five cancer-related deaths. Almost one third of patients with lung cancer do not receive any oncological treatment, either because of poor performance status, comorbidities or the extent of the disease. Half of the patients have metastatic disease at diagnosis, resulting in only small improvements in survival despite advances in the treatment of lung cancer patients. These data remind us that if we are to make major shifts in the management of lung cancer patients, we will need to take different approaches. The most promising seems to be the detection of early stages of lung cancer which offers the best treatment results. The Recommendations written here are guidelines for the management of patients with lung cancer. Only with comprehensive multidisciplinary treatment approach, the best outcome from the prognostically unfavourable disease can be offered

Posodobitev Priporočil tri leta po izidu izvirnika prinaša največ novosti v poglavju o sistemskem zdravljenju bolnikov s pljučnim rakom. To kaže na izjemen napredek na področju razumevanja onkogeneze in biologije pljučnega raka ter s tem razvoja novih zdravil. Breme pljučnega raka ostaja veliko, saj je pljučni rak pri nas in v svetu še vedno najpogostejši vzrok smrti zaradi raka. Za vsako peto smrt zaradi raka je odgovoren pljučni rak. Skoraj tretjina bolnikov s pljučnim rakom ne prejme specifičnega onkološkega zdravljenja, bodisi zaradi slabega stanja zmogljivosti, spremljajočih bolezni ali obsega bolezni. Polovica bolnikov ima ob diagnozi razsejano bolezen, zaradi česar izboljšanje preživetja z malimi koraki sledi napredku v zdravljenju bolnikov s pljučnim rakom. Ti podatki nas opominjajo, da se bomo morali za velike premike v obravnavi bolnikov s pljučnim rakom lotiti drugačnih pristopov. Kot najbolj obetavno se ponuja zgodnje odkrivanje bolezni, ko so možnosti ozdravitve pljučnega raka najboljše. Zapisana Priporočila so usmeritev za obravnavo bolnikov s pljučnim rakom. Le s sodobnim multidisciplinarnim pristopom obravnave lahko bolniku ponudimo zdravljenje, ki mu omogoča najboljši izhod prognostično neugodne bolezni
