Moreover, AC patients showed impaired LV-GLS (p<0.001), LV-GRS (p<0.001), LV-GCS (p<0.001) and RV-GRS (p0.026) as compared to control subjects. Group1 patients showed a significant reduction of LV-GRS (p<0.05) and LV-GCS p<0.01) as compared to control subjects. At univariate analysis LV-GCS was the most discriminatory parameter between Group1 vs heathy subjects with an optimal cut-off of -15.8 (Sensitivity 74%; Specificity 10%).

In patients with AC biopsy-proven, CMR-FT could improve the diagnostic yield in the subset of patients who results negative for imaging TFC criteria resulting as useful gatekeeper for indication of myocardial biopsy in case of equivocal clinical and imaging presentation.

Refractory hyperkalemia and hypervolemia with oligoanuria prompted initiation of hemodialysis. His serum albumin was 2.6g/dL and his urinary protein-creatinine ratio was 2,321mg/mmol. Given a high suspicion for rapidly progressive glomerulonephritis, empirical glucocorticoid treatment was initiated (3 methylprednisolone pulses followed by high-dose prednisone). A kidney biopsy showed MCD and acute tubular injury. Kidney function and proteinuria subsequently improved, and hemodialysis was discontinued 38 days after the start of therapy. This case describes de novo MCD after the Oxford-AstraZeneca vaccine. It adds to the few published case reports of MCD after the Pfizer-BioNTech COVID-19 vaccine. Further reports and studies will be needed to elucidate whether MCD is truly associated with COVID-19 vaccination.

The phase angle (PhA) is a measure of great clinical relevance provided through the Bioelectric Impedance Analysis (BIA). PhA is related to health status. Physical performance measures are also similarly associated to the health status of older individuals, however, studies which asses the relationship between these two measures are scarce.

To identify the relationship between PhA and physical performance measures in community-dwelling older adults in a Brazilian sample.

This was a cross-sectional study in which 200 community-dwelling older adults up to 65years of age of both genders were recruited. Physical performance was evaluated by walking speed and handgrip strength, and the PhA was derived from BIA. Linear regression models were used to estimate the associations between PhA and physical performance measures. Two models were built the first model was adjusted by handgrip and walking speed; and the second model additionally included the number of chronic diseases, gender, age and body mass index (BMI).

A total of 200 subjects were evaluated through BIA. Men showed a mean age of 72.13±3.42years and women 71.94±3.35years. Mean PhA among men was 5.99±0.67, while the mean obtained for women was 5.43±0.70. Linear regression showed that handgrip strength (β 0.036; p-value < 0.001; β 0.024; p-value 0.005) and walking speed (β 0.495; p-value 0.044; β 0.619, p-value 0.009) were correlated with the PhA in both models.

The results of our study revealed that PhA is a good marker of physical performance for the Brazilian community-dwelling older adults studied.

The contents of the nucleus are surrounded by the nuclear envelope, which acts as a hub of mechanosensation, transducing forces from the external cytoskeleton to the nucleus, thus impacting on nuclear morphology, genome organisation, gene transcription and signalling pathways. Muscle tissues such as the heart are unique in that they actively generate large contractile forces, resulting in a distinctive mechanical environment which impacts nuclear properties, function and mechanosensing. In light of this, mutations that affect the function of the nuclear envelope (collectively known as nuclear envelopathies and laminopathies) disproportionately result in striated muscle diseases, which include dilated and arrhythmogenic cardiomyopathies. Here we review the nucleus and its role in mechanotransduction, as well as associated defects that lead to cardiac dysfunction.Following the emergence of electronic cigarette, or vaping product use associated lung injury (EVALI) in 2019 in the US, regulation of e-cigarettes has become globally tighter and the collective evidence of the detrimental effects of vaping has grown. The danger of cellular distress and altered homeostasis is heavily associated with the modifiable nature of electronic cigarette devices. An array of harmful chemicals and elevated concentrations of metals have been detected in e-cigarette aerosols which have been linked to various pathogeneses. Vaping is linked to increased inflammation, altered lipid homeostasis and mitochondrial dysfunction whilst also increasing microbial susceptibility whilst the long-term damage is yet to be observed. The scientific evidence is mounting and highlighting that, along with traditional tobacco cigarette smoking, electronic cigarette vaping is not a safe practice.

HIV-infected patients with Pneumocystis-pneumonia (PCP) may develop paradoxical immune reconstitution inflammatory syndrome (IRIS), when combination antiretroviral therapy (cART) is started early during the course of PCP-treatment (PCPT). The aim of this study was to identify risk factors and predictors for PCP-IRIS and to improve individualized patient care.

An ICD-10 code hospital database query identified all Frankfurt HIV Cohort patients being diagnosed with PCP from January 2010 - June 2016. Patient charts were evaluated retrospectively for demographic, clinical and therapeutic (cART/PCPT) characteristics and incidence of paradoxical IRIS according to French's case definitions.

IRIS occurred in 12/97 patients that started cART while on PCPT (12.4%). They had a higher rate of re-hospitalization (41.7vs. 4.7%; odds ratio (OR) 14.46; p=0.009), intensive care treatment (66.7vs. 30.6%; OR=4.54; p=0.018), and longer median hospitalization (48 days vs. 23; p<0.001). A high HIV-RNA level (>6Log

/ml) before cART initiation was associated with IRIS development (41.6vs. 15.0%; OR 4.05; p=0.042). Serum immunoglobulin G-levels (IgG) [mg/dl] were lower (894.0vs. 1446.5; p=0.023).

Higher hospitalization rate and morbidity parameters underscore the clinical importance of PCP-related paradoxical IRIS. A baseline viral load of >6Log10/ml and serum IgG may help to assess individual risks for PCP-IRIS.

This synapse is best known for undergoing extensive morphological and functional changes throughout early development and thereby has served as a prominent model system to study presynaptic mechanisms of neurotransmitter release. However, the pivotal roles of N-methyl-d-aspartate receptors (NMDARs) in gating acute forms of activity-dependent, persistent plasticity in vitro and chronic developmental remodeling in vivo are hardly noted. This article will provide a retrospective review of key experimental evidence to conceptualize the impact of a transient abundance of NMDARs during the early postnatal stage on the functionality of fast-spiking central synapses while raising a series of outstanding questions that are of general significance for understanding the developing brain in health and diseases.Heat shock protein 90 (HSP90) is a highly conserved molecular chaperone that plays a pivotal role in folding, activating and assembling a variety of client proteins. In addition, HSP90 has recently emerged as a crucial regulator of vesicular transport of cellular proteins. In our previous study, we revealed Rab11b negatively regulated osteoclastogenesis by promoting the lysosomal proteolysis of c-fms and RANK surface receptors via the axis of early endosome-late endosome-lysosomes. In this study, using an in vitro model of osteoclasts differentiated from murine macrophage-like RAW-D cells, we revealed that Rab11b interacted with both HSP90 isoforms, HSP90 alpha (HSP90α) and HSP90 beta (HSP90β), suggesting that Rab11b is an HSP90 client. Using at specific blocker for HSP90 ATPase activity, 17-allylamino-demethoxygeldanamycin (17-AAG), we found that the HSP90 ATPase domain is indispensable for maintaining the interaction between HSP90 and Rab11b in osteoclasts. Nonetheless, its ATPase activity is not required for regulating the turnover of endogenous Rab11b. Interestingly, blocking the interaction between HSP90 and Rab11b by either HSP90-targeting small interfering RNA (siHSP90) or 17-AAG abrogated the inhibitory effects of Rab11b on osteoclastogenesis by suppressing the Rab11b-mediated transport of c-fms and RANK surface receptors to lysosomes via the axis of early endosome-late endosome-lysosomes, alleviating the Rab11b-mediated proteolysis of these surface receptors in osteoclasts. Based on our observations, we propose a HSP90/Rab11b-mediated regulatory mechanism for osteoclastogenesis by directly modulating the c-fms and RANK surface receptors in osteoclasts, thereby contributing to the maintenance of bone homeostasis.Only few genes are known from insects that encode multiple neuropeptides, i.e., peptides that activate different receptors. Among those are the capa and pk genes, which differentiated within Hexapoda following gene duplication. In our study, we focus on the early stages of differentiation of these genes. Specifically (1) What was the expression pattern of the ancestral capa/pk gene, i.e., prior to gene duplication? (2) What is the expression pattern of capa and pk in silverfish, whose ancestors diverged from Pterygota more than 400 mya? Our results suggest the location and projection of CAPA immunoreactive Va cells in abdominal ganglia (trunk ganglia in Remipedia) are a plesiomorphic trait that was already present in the ancestor of Remipedia and Hexapoda. General features of serial homology such as location of cells bodies, contralateral projection of primary neurites, and presumed peripheral peptide release from segmentally arranged neurohemal release sites could be observed in Remipedia and silverfish, but also in all Pterygota studied so far. Differences are mainly in the specific location of these peripheral release sites. This hypothetical basic pattern of capa/pk neurons underwent modifications in the anterior ganglia of the ventral nerve cord already in Remipedia. In silverfish, as in all Pterygota studied so far, pk expression in the CNS is apparently restricted to the gnathal ganglia, whereas capa expression is typical of abdominal Va cells. Thus, differentiation in the expression pattern of capa and pk genes occurred early in the evolution of Hexapoda; likely soon after the appearance of two separate genes.
