Chronic kidney disease (CKD) patients have lower pulmonary function, respiratory and peripheral muscle strength values when compared to the general population, which reflects negatively in the quality of life (QoL). The aim of this study was to compare the pulmonary function, respiratory and peripheral muscle strength, and QoL between CKD patients and healthy individuals. Cross-sectional study with a consecutive sample of 39 individuals separated into three groups nondialysis-dependent CKD in stage 5 (CKD-5), HD group (CKD-HD), and healthy individuals. The tests performed were spirometry, manovacuometry, handgrip strength (HGS), and Medical Outcomes Short-Form Health Survey (SF-36). A significant difference between groups was observed in forced expiratory volume in 1 second (FEV1 ) and its predicted value (p = 0.004 and p  less then  0.001, respectively), forced vital capacity (FVC), and its predicted value (p = 0.008 and p  less then  0.001, respectively), peak expiratory flow (PEF) and its predicted value (p = 0.004 and p  less then  0.001, respectively), maximal inspiratory pressure (MIP) and its predicted value (p = 0.022), maximal expiratory pressure (MEP) and its predicted value (p = 0.030 and p = 0.009, respectively) in which CKD-5 presented the worst values, followed by CKD-HD and healthy group. The CKD-5 had worse pulmonary function, respiratory muscle strength, and QoL. Moreover, CKD-HD also showed some impairment in pulmonary function and QoL when compared with healthy individuals. Even with the peripheral muscle strength preserved, its decrease is proportional to the pulmonary impairment in the evaluated CKD patients.Imaging plays a fundamental role in all aspects of the cancer management pathway. However, conventional imaging techniques are largely reliant on morphological and size descriptors that have well-known limitations, particularly when considering targeted-therapy response monitoring. Thus, new imaging methods have been developed to characterise cancer and are now routinely implemented, such as diffusion-weighted imaging, dynamic contrast enhancement, positron emission technology (PET) and magnetic resonance spectroscopy. However, despite the improvement these techniques have enabled, limitations still remain. Novel imaging methods are now emerging, intent on further interrogating cancers. These techniques are at different stages of maturity along the biomarker pathway and aim to further evaluate the cancer microstructure (vascular, extracellular and restricted diffusion for cytometry in tumours) magnetic resonance imaging (MRI), luminal water fraction imaging] as well as the metabolic alterations associated with cancers (novel PET tracers, hyperpolarised MRI). Finally, the use of machine learning has shown powerful potential applications. By using prostate cancer as an exemplar, this Review aims to showcase these potentially potent imaging techniques and what stage we are at in their application to conventional clinical practice.Perovskite solar cells (PSCs) are attracting a tremendous attention from the scientific community due to their excellent power conversion efficiency, low cost, and great promise for the future of solar energy. The best PSCs have already achieved a certified power conversion efficiency (PCE) of 25.5 % after an unprecedented rapid performance rise. However, high requirements with respect to large area, high-efficiency devices, and stability are still the challenges. Major efforts, especially for achieving a high degree of chemical control, have been made to reach these targets. The use of halide additives has played a critical role in improving the efficiency and stability. The present paper reviews the important breakthroughs in PSC technologies made by using halide additives, especially chloride, and pseudo-halide additives for the preparation of the perovskite layers, other layers, and interfaces of the devices. These additives help perovskite (PVK) crystallization and layer morphology control, grain boundary reduction, bulk and interface defects passivation, and so on. Normally, these halide additives play different roles depending on their categories and their location. Herein, recent progresses made due to additives employment in every possible layer of PSCs are reviewed, with focus on chloride, other halides, and pseudo-halides as additives in PVK films, halide additives in carrier transport layers, and at PVK-contact interfaces. Finally, an outlook of engineering of these additives in PSC progress is given.A1 R-A2A R heterodimers regulate striatal glutamatergic neurotransmission. However, few researches about kinetics have been reported. Here, we combined Iem-spFRET and E-FRET to investigate the kinetics of A1 R and A2A R interaction. Iem-spFRET obtains the energy transfer efficiency of the whole cell. E-FRET gets energy transfer efficiency with high spatial resolution, whereas, it was prone to biases because background was easily selected due to manual operation. To study the interaction with high spatio-temporal resolution, Iem-spFRET was used to correct the deviation of E-FRET. In this paper, A1 R and A2A R interaction was monitored, and the changes of FRET efficiency of the whole or/and partial cell membrane were described. The results showed that activation of A1 R or A2A R leads to rapid aggregation, inhibition of A1 R or A2A R leads to slow segregation, and the interaction is reversible. These results demonstrated that combination of Iem-spFRET and E-FRET could measure A1 R and A2A R interaction with high spatio-temporal resolution.

This study aimed to evaluate nocturnal oximetry approaches in identifying obstructive sleep apnea (OSA) among bariatric surgical candidates.

This was a cross-sectional study involving adult bariatric patients who were undergoing in-lab polysomnography and who were previously screened with the GOAL questionnaire. OSA severity was established as any OSA, moderate/severe OSA, and severe OSA. Oximetry data were evaluated as oxygen saturation (average and nadir), oxygen desaturation index (ODI) at 3%, and proportion of time spent with oxygen saturation <90%. Associations between oximetry data and the apnea-hypopnea index (AHI) were assessed by Spearman correlation index (r), linear regression, logistic regression, and discrimination.

All oximetry values were significantly correlated with the AHI among 1,178 individuals, with the ODI emerging as the better parameter (r = 0.911, p < 0.001). Using linear regression, the ODI was the only predictor of the AHI (β = 0.952, p < 0.001). In the multivariate analysis, the ODI was the only independent parameter predicting OSA at all severity levels. In addition, the ODI exhibited excellent discrimination to predict OSA and displayed improved performance among individuals screened as being at high risk versus those at low risk with the GOAL instrument.

The ODI emerges as a valid surrogate predictor of the AHI, particularly among those screened as being at high risk for OSA.

Physical examination revealed multiple subcutaneous hematomas, gingival hyperplasia, bilateral knee effusion, lower extremities muscle weakness, and right hip joint movement limitation. The laboratory tests were remarkable only for iron and folate deficiency normocytic anemia (Hemoglobin 9 mg/dl). JAK drugs The Magnetic Resonance Imaging (MRI) findings in the coronal STIR sequence of the hips (Image A) revealed bone marrow edema in the right proximal femur (femoral head, neck, intertrochanteric and subtrochanteric regions), right hip joint effusion, edema of the right buttock muscles and bilateral proximal thigh muscles, and perifascial edema around bilateral external obturator muscles; similar changes were demonstrated on the right knee coronal and sagittal T2-weighted fat saturated MRI (Images B, C). Vitamin C's undetectable blood levels confirmed Scurvy; treatment with Vitamin C and Multivitamins led to full recovery. Subsequently, we found out that the patient suffers from a selective eating disorder and has restricted her diet to rice and non-fortified yogurt.

Kelch-like ECH-associated protein 1 (KEAP1) has been identified as a cancer driver gene in lung adenocarcinoma (LUAD), and increased evidence has given us clues about the association of KEAP1 mutation and immune characteristics. We assessed the association between KEAP1 mutation and tumor microenvironment in LUAD systematically.

With the data collected from The Cancer Genome Atlas (TCGA), we evaluated the association of KEAP1 mutation with tumor infiltrating leukocytes (TILs), including dendritic cell, CD8 T cell, CD4 T cell, neutrophil, B cells, and macrophage. Expression differences of the markers of those immune cells were also measured. We further compared the expression of antigen presentation genes and chemokines and the enrichment score of immune-related pathways.

KEAP1 mutation had significant association with lower TILs and cytotoxic T lymphocyte. Strikingly, almost all of antigen presentation genes and chemokine showed lower expression in KEAP1-mutated tumors. Moreover, most of immune-related pathways were less active in KEAP1-mutated tumors. As expected, KEAP1-wild type LUADs favored better overall survival after immunotherapy. Finally, one patient harboring KEAP1 mutation along with a lack of immune cells infiltration in tumor microenvironment failed to respond to checkpoint inhibitor despite high tumor mutational burden (TMB).

KEAP1 mutation has a significant effect on the tumor immune milieu of LUAD and may play as a predictive biomarker of immunotherapy for LUAD patients.

Solutions to improve the implementation of shared decision making (SDM) in oncology often focus on the consultation, with limited effects. In this study, we used a service design perspective on the care path of locally advanced pancreatic cancer (LAPC). We aimed to understand how experiences of patients, their significant others, and medical professionals over the entire care path accumulate to support their ability to participate in SDM.

We used qualitative interviews including design research techniques with 13 patients, 13 significant others, and 11healthcare professionals, involved in the diagnosis or treatment of LAPC. The topic list was based on the literature and an auto-ethnography of the illness trajectory by a caregiver who is also a service design researcher. We conducted a thematic content analysis to identify themes influencing the ability to participate in SDM.

We found four interconnected themes (1) Decision making is an ongoing and unpredictable process with many decision moments, often is often set outside the consultation, which might explain the limited effect currently seen of interventions focusing on consultation itself. Our findings serve as a starting point for (re)designing care paths to improve the implementation of SDM in oncology.
