Adrenal insufficiency (AI) is characterized by higher mortality and morbidity compared with the general population. Conventional replacement steroid therapy, currently recommended for the treatment of AI, is associated with increased frequency of metabolic comorbidities due to daily overexposure. By contrast, dual-release hydrocortisone is associated with a decreased risk of metabolic comorbidities, providing an adequate release of hydrocortisone and mimicking the physiological profile of cortisol. These favorable effects are due to a reduced daily steroid exposure that does not affect the expression of the clock genes which are involved in metabolic pathways and are regulated by the normal physiological circadian rhythm of endogenous cortisol. This narrative review focuses on the possible metabolic comorbidities of AI due to steroid replacement therapy, which evaluates the effects of conventional and novel drugs with attention to chronopharmacology.
Diagnosis of infections in returning international travellers can be challenging because of the broad spectrum of potential infectious etiologies potentially involved. Viral metagenomic next-generation sequencing (mNGS) has the potential to detect any virus present in a patient sample and is increasingly being used for difficult to diagnose cases. The aim of this study was to analyze the performance of mNGS for viral pathogen detection in the clinical setting of international travellers returning with febrile illness.

Thirty-eight serum samples from international travellers returning with febrile illness and presenting at the outpatient clinic of the Leiden University Medical Center in the Netherlands in the time period 2015-2016 were selected retrospectively. Samples were processed for viral metagenomic sequencing using a probe panel capturing all known vertebrate viruses. Bioinformatic analysis was performed using Genome Detective software for metagenomic virus detection. Metagenomic virus findings werenal travellers with a febrile syndrome. this website Furthermore, viral enrichment by probes resulted in high genome coverage and depth which enabled dengue virus typing.
Human pegivirus 1 (HPgV1) may cause persistent infections in immunocompetent and immunosuppressed individuals. Its clinical relevance, however, has not been determined. Previous studies have described a higher prevalence of HPgV1 infection in organ transplant recipients compared to healthy controls, but its occurrence in lung transplant recipients (LTRs) and its association with immunosuppressive therapy has not been assessed.

The aim of this study was to evaluate the prevalence and clinical significance of HPgV1 infection in LTRs, and to compare HPgV1 loads and kinetics to Torque Teno Virus (TTV) kinetics, which reflects the level of immunosuppression.

From each of 110 LTRs, five consecutive plasma samples were collected within the first year after transplantation and tested for HPgV1 RNA and TTV DNA loads by quantitative PCR. Data were related to demographic data and clinical parameters followed up for 3 years post transplantation.

HPgV1 prevalence in LTRs was 18,2%. HPgV1 detection was significantly associated with younger age, but not with graft rejections or other microbial infections. The viral replication level remained unaffected by immunosuppressive therapy. This was in contrast to TTV loads which increased after initiation of immunosuppressive therapy, independent of the patients' HPgV1 infection status.

In contrast to TTV, HPgV1 kinetics do not reflect the level of immunosuppression after lung transplantation, and there is no correlation between the replication of both persistent viruses in the post transplantation follow up. Thus the individual virus host interactions seem to differ substantially and require further investigation.

The properties of IEDs most detrimental to memory, however, are undefined. We studied the impact of temporal and spatial characteristics of IEDs on list learning. Subjects completed a memory task during intracranial EEG recordings including hippocampal depth and temporal neocortical subdural electrodes. Subjects viewed a series of objects, and after a distracting task, recalled the objects from the list. The impacts of IED presence, duration, and propagation to neocortex during encoding of individual stimuli were assessed. The effects of IED total number and duration during maintenance and recall periods on delayed recall performance were also determined. The influence of IEDs during recall was further investigated by comparing the likelihood of IEDs preceding correctly recalled items vs. periods of no verbal response. Across 6 subjects, we analyzed 28 hippocampal and 139 lateral temporal contacts. Recall performance was poor, with a median of 17.2% correct responses (range 10.4-21.9%). Interictal epileptiform discharges during encoding, maintenance, and recall did not significantly impact task performance, and there was no significant difference between the likelihood of IEDs during correct recall vs. periods of no response. No significant effects of discharge duration during encoding, maintenance, or recall were observed. Interictal epileptiform discharges with spread to lateral temporal cortex during encoding did not adversely impact recall. A post hoc analysis refining model assumptions indicated a negative impact of IED count during the maintenance period, but otherwise confirmed the above results. Our findings suggest no major effect of hippocampal IEDs on list learning, but study limitations, such as baseline hippocampal dysfunction, should be considered. The impact of IEDs during the maintenance period may be a focus of future research.The aim of the study was to assess the self-reported burden of disease in people with idiopathic/genetic generalized epilepsy and risk factors associated with high disease burden. We performed a nationwide online survey on epilepsy characteristics/treatment, quality of life/daily living followed by Standardized Assessment of Personality-Abbreviated Scale, Major Depression Inventory, Barratt Impulsiveness Scale (brief) and the brief Epilepsy Anxiety Survey Instrument. The survey was sent to 275 representative patients with IGE ('Funen cohort') and later publicly distributed via the Danish Epilepsy Association. The characteristics of the responders of the 'Funen cohort' (n = 119) did not differ from non-responders and previously assessed data. Out of 753 persons accessing the public survey, 167 had probable IGE. As compared to the 'Funen cohort', patients from the public survey reported similar age, time since last seizure, years with disease, seizure types, and IGE syndromes but more current and previously triimpulsivity, depression, anxiety, and personality disorders.
Focal onset epilepsy carries a higher risk of intractability than generalized onset epilepsy. Knowledge of the risk factors of intractability will help guide the treatment of children with focal epilepsy. In addition to risk factors present at initial diagnosis, the evolution of clinical and electroencephalographic features may also play a role in predicting intractability.

A prospective cohort study was done on children aged one month to three years with newly diagnosed focal epilepsy. Initial treatment of carbamazepine was given according to a standard protocol after assessment of clinical manifestations, neurologic and developmental status, EEG, and brain MRI. Depending on response to therapy, subjects may also receive valproic acid or phenobarbitone following the protocol. Follow-up was done in the second week and every month thereafter. At the end of the study period, seizure type was re-assessed and a repeat neurological and developmental examination and EEG was obtained to evaluate the role of clinical and EEG evolution in predicting intractability.

Out of 71 subjects, 21 (29.6%) had intractable epilepsy at the end of the study period. Age of onset (p = 0.216) and neurological status (p = 0.052) were not associated with intractable epilepsy. On logistic regression analysis, evolution of seizure type (p < 0.001; RR 56.45; 95%CI 6.56 to 485.85) and evolution of background EEG rhythm (p < 0.001; RR 56.51; 95%CI 2.77 to 1152.16) were significantly associated with intractable epilepsy.

Changes in seizure type and baseline EEG rhythm may predict intractability in children one month to three years of age with focal epilepsy.

However, one of the technical concerns is the size of the gold-nanocrystals, which are larger than the protein. In our previous results of mean square angular displacement curves in DXT analysis, dynamical movements of the DNA-binding protein, c-Myb R2R3, were observed in only one population in either DNA-unbound or -bound state, and was found to decrease upon DNA binding. In this study, c-Myb R2R3 dynamical movements were re-evaluated with a low density of the protein immobilized on the DXT substrate, to decrease the possibility that the gold-nanocrystals attached to more than one R2R3 molecule. We observed two dynamical moving populations in the DNA-bound state, which could be classified due to electrostatic attraction and repulsion between the DNA-protein complexes, and determined the apparent angular diffusion constant, which was similar to the value calculated in our previous study. We showed more real movement of the protein could be observed by lowering the immobilization density of the protein.
The objective of this study was to evaluate the relationship between clinical features and the presence of infection on thoracic and abdominal tomography (CT) scans in emergency department (ED) patients with acute febrile illness without apparent source.

Patients aged 18 years and over who presented to ED with acute fever of unknown origin between January 1, 2020 and December 31, 2020 and underwent CT imaging (thoracic and abdomen) as a diagnostic test were included in the study retrospectively. Acute fever of unknown origin was defined as the absence of a history or physical examination finding that could explain the possible cause of fever, normal values of parameters that would suggest an infection in the urine analysis, and absence of infiltration on chest X-ray. The patients were divided into two groups according to the presence and absence of a source of infection on CT. The clinical and demographic data of the patients were evaluated. The effect of clinical factors on the presence of infection in CT scans was determined using the logistic regression analysis.

Among the 173 patients included in the study, the CT scans were positive for the source of infection in 31.2% (n = 54) and negative in 68.8% (n = 119). In the multiple logistic regression analysis, age ≥ 65 years [odds ratio (OR) 2.72, 95% confidence interval (CI)1.15-4.35, p < 0.001), presence of comorbidity (OR2.37, 95%CI1.08-4.14, p = 0.033), and procalcitonin positivity (PCT) (OR 2.54, 95%CI 1.29-4.95, p = 0.006) were identified as risk factors for the presence of infection in CT.

Patient's age, presence of comorbidity and PCT level should be considered when deciding on the use of CT in determining the source of infection in acute febrile patients without clinical clues.
