The DSCFO detected substantial changes in forearm blood flow and oxygenation resulting from the artery occlusion, which meet physiological expectations and are consistent with previous study results.

The wearable DSCFO may be used for continuous and simultaneous monitoring of blood flow and oxygenation variations in freely behaving subjects.

A global downtrend in blood usage has been observed by many countries, while the demand for antigen-negative red blood cell (RBC) units used in antigen-matched transfusions keeps increasing. The declining number of units collected exposes blood providers to a rapidly evolving supply challenge.

This study was conducted retrospectively with use of internal data analysis to weigh Québec's situation regarding global and antigen-negative RBC demand, to measure the effects of community-directed recruitment and blood drives, and to evaluate the benefits of mass-scale RBC genotyping.

Our findings confirm a global RBC usage downtrend of over 20% total in the past 10 years with a steady antigen-negative usage and highlight the most requested negative antigen combinations. Marizomib solubility dmso Our data also show our +39.5% progress regarding the number of Black donors recruited for antigen matching of patients with sickle cell disease in the past 3 years, as well as a constantly growing number of just-in-time blood collection for complex orders. Finally, our data summarize the efficiency of our mass-scale RBC genotyping efforts.

Altogether, this study confirms the demand trends for regular and antigen-negative RBC units in Québec and the efficient effects of our recruitment and typing strategies.

This study aims to evaluate whether preoperative serum albumin-to-globulin ratio (AGR) could predict the prognosis of patients with urothelial bladder cancer (UBC) after radical cystectomy (RC).

A total of 176 patients with UBC who underwent RC in a tertiary hospital between 2008 and 2019 were retrospectively analyzed. The AGR was calculated as albumin/(total protein - albumin). In addition, the AGR was divided into two groups for the time-dependent receiver operating characteristic curve (ROC) analysis. Survival was estimated using the Kaplan-Meier analysis and compared using the log-rank test. Cox proportional- hazards models were used for multivariate survival analysis.

The best cutoff AGR value for metastasis prediction was 1.32 based on the ROC curve analysis. Patients who had lower pretreatment AGR (<1.32) values composed the low-AGR group (n = 57; 32.4%). On the other hand, the remaining patients (n = 119; 67.6%) composed the high-AGR group. The patients in the low-AGR group had more advanced stage tumors compared with the patients in the high-AGR group. The Kaplan-Meier curves revealed that the patients in the low-AGR group had significantly lower rates of metastasis-free survival (MFS) and cancer-specific survival (CSS). The multivariate Cox regression analysis showed that preoperative AGR was an independent prognostic factor for MFS and CSS.

In this single-institution retrospective study, lower preoperative AGR values demonstrated a poor prognostic effect on MFS and CSS in patients with UBC who underwent RC.

Serum thyroglobulin levels are often elevated in Graves' disease (GD) and in most cases decrease during treatment. Its relation to Graves' orbitopathy (GO) has not been clarified. Previously, a risk of GO has been linked to smoking, TSH receptor stimulation, high TSH-receptor antibodies (TRAb), low thyroid peroxidase and thyroglobulin antibodies (TPOAb, TgAb).

We examined Tg levels in 30 consecutive patients with GD were given drug therapy (methimazole + thyroxine) for up to 24months. GO was identified by clinical signs and symptoms. 17 patients had GO, 11 of whom had it at diagnosis while 6 developed GO during treatment. During the study, 5 subjects were referred to radioiodine treatment, 3 to surgery. The remaining 22 subjects (GO n = 12, non-GO n = 10) completed the drug regimen.

At diagnosis, Tg levels in GO patients (n = 11) were higher (84, 30-555µg/L, median, range) than in non-GO patients (n = 19) (38, 3.5-287µg/L), p = 0.042. Adding the 6 subjects who developed eye symptoms during treatment to the GO group (n = 17), yielded p = 0.001 vs. non-GO (n = 13). TRAb tended to be higher, while TPOAb and TgAb tended to be lower in the GO group. For the 22 patients who completed the drug regimen, Tg levels were higher in GO (n = 12) vs. non-GO (n = 10), p = 0.004, whereas TRAb levels did not differ.

The data may suggest that evaluation of thyroglobulin levels in GD could contribute to identify patients at increased risk of developing GO. Possibly, thyroidal release of Tg in GD reflects a disturbance that also impacts retroorbital tissues.

The relationship between urinary excretion rate of glucose (UEGL) and uric acid (UA) metabolism in adults with type 2 diabetes (T2D) remains unclear to date. This study aimed to investigate the relationships of UEGL with serum UA (SUA), urinary excretion rate of uric acid (UEUA), and renal clearance of uric acid (CLUA) in adults with T2D. We hypothesised that high UEGL increases UA excretion, which in turn leads to lower SUA.

This was a cross-sectional study of 635 inpatients with T2D recruited between 2018 and 2019. The relationships of UEGL with UEUA, CLUA, and hyperuricaemia were assessed using analysis of covariance and multivariate regression analysis.

Patients in the higher quartile of UEGL tended to have lower SUA levels than those in the lower quartile. In contrast, patients in the higher quartile of UEGL tended to have higher CLUA (p for trend < 0.0001), and a similar trend was observed for UEUA. In adjusted multivariable linear regression model, UEGL was negatively correlated with SUA (β = -0.
