BACKGROUND: Functional electrical stimulation-assisted cycle ergometry (FESCE) can deliver active exercise to critically ill patients, including those who are sedated. Aerobic exercise is known to stimulate skeletal muscle glucose uptake. We asked whether FESCE can reduce intravenous insulin requirements and improve insulin sensitivity in intensive care unit (ICU) patients. METHOD: We performed an a priori-planned secondary analysis of data from an outcome-based randomized controlled trial (NCT02864745) of FESCE-based early-mobility program vs standard of care in mechanically ventilated patients. We analyzed glucose profile, glucose intake, and insulin requirements during ICU stay in all enrolled patients. In a nested subgroup, we performed hyperinsulinemic (120 mIU/min/m2 ) euglycemic clamps at days 0, 7, and 180 (n = 30, 23, and 11, respectively). RESULTS: We randomized 150 patients 1:1 to receive intervention or standard of care. Seventeen (23%) patients in each study arm had a history of diabetes. During ICU stay, patients received 137 ± 65 and 137 ± 88 g/day carbohydrate (P = .97), and 31 vs 35 (P = .62) of them required insulin infusion to maintain blood glucose 8.61 ± 2.82 vs 8.73 ± 2.67 mM (P = .75, n = 11,254). In those treated with insulin, median daily dose was 53 IU (interquartile range [IQR], 25-95) vs 62 IU (IQR, 26-96) in the intervention and control arm, respectively (P = .44). In the subgroup of patients undergoing hyperglycemic clamps, insulin sensitivities improved similarly and significantly from acute and protracted critical illness to 6 months after discharge. CONCLUSION: The FESCE-based early-mobility program does not significantly reduce insulin requirements in critically ill patients on mechanical ventilation.

BACKGROUND: Plaque-induced gingivitis is the most prevalent periodontal disease associated with pathogenic biofilms. The host immune system responds to pathogens through pattern recognition receptors (PRRs), such as Toll-like receptors (TLRs) and their co-receptor cluster of differentiation 14 (CD14). AIM: This study investigated the association between the functional polymorphism in the CD14 gene and the dental plaque microbiota in children with gingivitis. DESIGN: A total of 590 unrelated children (307 with plaque-induced gingivitis and 283 controls, aged 13-15 years) were enrolled in this case-control study. Dental plaque was processed using a ParoCheck® 20 detection kit. The CD14 -260C/T (rs2569190) polymorphism was determined with the PCR-RFLP method. RESULTS: Gingivitis was detected in 64.2% of boys and 35.8% of girls (P < .001). Children with gingivitis had a significantly higher occurrence of dental caries (P < .001). No significant differences in the CD14 -260C/T allele and genotype distribution among individuals with or without gingivitis in the whole cohort were found. Children with gingivitis and P gingivalis, however, were significantly more frequent carriers of the CT and TT genotypes than children with gingivitis without P gingivalis or healthy controls (P < .05). CONCLUSIONS: The CD14 -260C/T polymorphism acts in cooperation with P gingivalis to trigger plaque-induced gingivitis in Czech children.

BACKGROUND: Patients with MS should be provided palliative care, which could help them manage symptoms more efficiently and could solve some psychosocial problems. Evaluating the satisfaction with provided care may be one of the factors of the quality of care evaluation. AIM: The aim of this controlled intervention study was to determine the factors affecting one's satisfaction with care in patients in advanced stages of MS and their caregivers. Furthermore, the aim was to study the difference in the satisfaction of patients and family members with the provided specialized palliative care, as opposed to the standard care. METHODS: The sample consisted of 103 patients with MS who were randomized to either a palliative care intervention or the control group. Family members of each patient were invited in the study, and 97 caregivers agreed to participe. The patients in the intervention group were provided with neuropalliative care in the form of consultations with a multidisciplinary palliative team. A modified questionnaire, CANHELP Lite, was used to collect data. Patients and family members completed the questionnaire 3 months after the intervention. RESULTS: The patients and caregivers in the intervention group expressed significantly greater satisfaction in all analyzed areas (p = 0.000-0.002). The provided intervention predicted the satisfaction in the domains of a relationship with the doctor, disease management, and decision-making/communication. Another important predictor of the satisfaction in all domains was the functional state of the patient. CONCLUSION: Targeted consultations resulted in the greater satisfaction of patients with MS and their caregivers with the provided care.
Foci of splenic tissue separated from the spleen can occur as a congenital anomaly. Isolated nodules of splenic tissue are called accessory spleens or spleniculli. However, nodules of splenic tissue can merge with other organs during embryonic development, in which case we speak of spleno-visceral fusions: most often, they merge with the tail of the pancreas (thus forming spleno-pancreatic fusion or an intrapancreatic accessory spleen), with the reproductive gland (i.e., spleno-gonadal fusion), or with the kidney (i.e., spleno-renal fusion). Our case report describes the fusion of heterotopic splenic tissue with the right adrenal gland, which was misinterpreted as a metastasis of a renal cell carcinoma. To the best of our knowledge, this is the first reported case of spleno-adrenal fusion. Spleno-visceral fusions usually represent asymptomatic conditions; their main clinical significance lies in the confusion they cause and its misinterpretation as tumors of other organs. We believe that the cause of retroperitoneal spleno-visceral fusions is the anomalous migration of splenic cells along the dorsal mesentery to the urogenital ridge, together with primitive germ cells, at the end of the fifth week and during the sixth week of embryonic age. This theory explains the possible origin of spleno-visceral fusions, their different frequency of occurrence, and the predominance of findings on the left side.

OBJECTIVES: This study explored the quality of life (QoL) and attitudes to aging in older adults with and without dementia, and ascertained the main factors that predict QoL and attitude to ageing. METHODS: A cross-sectional study involving 563 community-dwelling adults with (PwD) and without dementia (PwoD) >60 years of age was conducted in three Czech regions. A tools battery including the Quality of Life-Alzheimer's Disease Scale, Geriatric Depression Scale, Patient Dignity Inventory, Attitude to Aging Questionnaire (AAQ), Short Physical Performance Battery, and Barthel Index, were administered. RESULTS: PwD had worse scores in QoL and AAQ (both p = 0.0001). Less depression (p < 0.001), better sense of dignity (p < 0.05), and lower pain (p < 0.05) in PwoD predicted better scoring for QoL and AAQ. Physical ability in PwoD (p < 0.05), living alone (p < 0.05) and self-sufficiency (p < 0.001) in PwDwere predictors influencing QoL.Age (p < 0.01) in PwoD, gender (p < 0.05) and physical ability (p < 0.001) in PwD influenced AAQ. CONCLUSIONS: This research is the first study to show that dignity can influence the QoL and attitude to aging in community-dwelling older adults. Our findings suggest that depression and dignity are common predictors of QoL and AAQ in older adults with and without dementia.

Tento návrh doporučeného postupu laboratorní diagnostiky dermatomykóz byl vypracován na základě odborné diskuze členů Pracovní skupiny pro mykologii Společnosti pro lékařskou mikrobiologii České lékařské společnosti JEP (PSM SLM ČLS JEP). Vychází z dokumentu „Doporučený postup laboratorní diagnostiky dermatomykóz“ zveřejněného na webových stránkách SLM ČLS JEP 23. 6. 2020 k všeobecné odborné diskuzi. Dosud byly pokyny v této oblasti mykologické laboratorní diagnostiky omezeny pouze na informace v příručkách a neexistoval žádný ucelený a systematický dokument na uvedené téma. Tuto mezeru se členové PSM SLM ČLS JEP snažili zaplnit, a vzniklo tak doporučení, pokrývající všechny části dermatomykologické laboratorní problematiky, od způsobu získání kvalitní anamnézy, správného postupu při odběru vzorků, jejich vyšetřování konvenčními mikroskopickými a kultivačními technikami, až po interpretaci získaných výsledků. Do této základní osnovy byly začleněny informace o diagnostickém potenciálu nových, moderních technologií, zejména molekulárně genetických metod a hmotnostní spektrometrie. Nedávno došlo k vypracování standardní evropské metodiky pro testování citlivosti dermatofytů k antimykotikům, proto byla i tato problematika do doporučení zahrnuta. Je samozřejmě počítáno s budoucí periodickou revizí tohoto dokumentu na základě nových poznatků.
This draft of guidelines for the laboratory diagnosis of dermatomycoses was developed based on discussion among members of the Czech Society for Medical Microbiology Working Group on Mycology. The document Guidelines for the Laboratory Diagnosis of Dermatomycoses was published for discussion on the Czech Society for Medical Microbiology website on 23 March 2020. Until recently, recommendations concerning this area of laboratory diagnosis in mycology were only limited to information in manuals and no comprehensive and systematic document concerning these issues was available. In an effort to fill the gap, members of the working group developed recommendations covering various laboratory aspects of mycology, from obtaining a proper history, to adequate sampling techniques, sample analyses using conventional microscopy and culture techniques, to interpretation of results. Additional information was on the diagnostic potential of novel, modern technology, in particular molecular genetic methods and mass spectrometry. The recently developed European standards for testing the susceptibility of dermatophytes to antifungals were also included in the recommendations. The document will be regularly updated based on new findings.
PURPOSE: The aim of this study was to present outcomes of operative treatment of the posterior malleolus fractures of type four of the Bartonicek/Rammelt classification. METHODS: In 19 patients, direct reduction and fixation of the posterior malleolus was performed from the posterolateral or posteromedial approaches. The accuracy of reduction was assessed with the use of postoperative CT scans. RESULTS: The mean size of the avulsed articular surface carried by posterior malleolus amounted to 36%. Reduction of the posterior malleolus fracture was assessed as anatomical in 14 cases and as satisfactory in five cases. Position of the distal fibula was assessed as anatomical in 15 cases. The mean AOFAS score was 89.4 points. All nine patients with anatomical reduction of all lesions achieved the mean AOFAS score of 93.1 points, five patients with malposition of posterior malleolus 89.1 points and five patients with malposition of the fibula in the fibular notch 87.8 points. A total of six patients developed osteoarthritic changes of grades one and two according to the Kellgren and Lawrence classification. CONCLUSIONS: Outcomes of the study demonstrated good mid-term results in type four fractures of the posterior malleolus treated by direct reduction from posterior approaches. Postoperative CT examination allowed evaluation of the accuracy of reduction of all fractures and reduction of the distal fibula into the fibular notch. Based on postoperative CT examination, it will be possible to assess the effect of reduction of individual lesions on the functional results.
Herein, we report an efficient synthetic approach towards trisubstituted imidazo [4,5-c]pyridines designed as inhibitors of Bruton's tyrosine kinase (BTK). Two alternative synthetic routes for the simple preparation of desired compounds with variable substitutions at the N1, C4, C6 positions were introduced with readily available building blocks. Further, the developed synthetic approach was feasible for isomeric compounds bearing imidazo [4,5-b]pyridine scaffolds. In contrast to expectations based on previous studies, the imidazo [4,5-c]pyridine inhibitor exhibited a significantly higher activity against BTK compared to its imidazo [4,5-b]pyridine isomer. An inherent SAR study in the series of imidazo [4,5-c]pyridine compounds revealed a remarkably high tolerance of C6 substitutions for both hydrophobic and hydrophilic substituents. Preliminary cellular experiments indicated selective BTK targeting in Burkitt lymphoma and mantle cell lymphoma cell lines. The inhibitors could thus serve as starting points for further development, eventually leading to BTK inhibitors that could be used after ibrutinib failure.

Interictal epileptiform discharge (IED) is a traditional hallmark of epileptic tissue that is generated by the synchronous activity of a population of neurons. Interictal epileptiform discharges represent a heterogeneous group of pathological activities that differ in shape, duration, spatiotemporal distribution, underlying cellular and network mechanisms, and their relationship to seizure genesis. The exact role of IEDs in epilepsy is still not well understood, and there remains a persistent dichotomy about the impact on IEDs on seizures. Proseizure, antiseizure, and no impact on ictogenesis have all been described in previous studies. In this article, we review the existing knowledge on the role of interictal discharges in seizure genesis, and we discuss how dynamical approaches to ictogenesis can explain the existing dichotomy about the multifaceted role of IEDs in ictogenesis. This article is part of the Special Issue "NEWroscience 2018".
