Immune cell function assay (ICFA) and CD3 lymphocyte counts have been considered to be useful in discerning the overall intensity of immunosuppression in pediatric orthotopic heart transplant (OHT) recipients.

The aim of this retrospective analysis was to evaluate trends of ICFA and CD3 lymphocyte counts and their association with adverse outcomes post-OHT.

A total of 381 ICFA and 493 CD3 laboratory values obtained in 78 patients within six months post-OHT were analyzed. There were 14 patients treated for biopsy-proven acute rejection, four of whom had ISHLT grade 2R/3A rejection. In patients with rejection versus those without, CD3 and ICFA values were 122 (IQR 74.5-308) cells/mm
and 224.5 (IQR 132-343.5) ng/ml compared to 231.8 (IQR 68-421) cells/m
and 191 (IQR 81.5-333) ng/mL (p=NS for both). Twenty-six patients had at least one detectable cytomegalovirus or Epstein-Barr virus DNAemia within the study timeframe. In patients with viremia versus those without, CD3 and ICFA values were 278.5 (IQR 68-552) cells/mm
and 130 (IQR 48-284) ng/ml compared to 195 (IQR 74.5-402.5) cells/mm
and 212 (IQR 89-342) ng/ml (p=NS for both).

No association was found between these immune markers and adverse outcomes. In the absence of larger pediatric studies justifying the role of these tests in identifying elevated risk profiles post OHT, we do not recommend their routine use.

Our study aimed to evaluate the association between NLR at COVID-19 diagnosis and survival during the following 90 days in hospitalized patients with solid cancer. Between May 2020 and June 2021, 120 patients were included in a retrospective cohort study. Univariable analysis showed patients with an NLR > 8.3 were associated with an increased risk of death (HR 4.34; 95% CI 1.74-10.84) compared to patients with NLR  8.3 is associated with an increased risk of death.
Therapeutic drug monitoring (TDM) of β-lactam antibiotics provides critical knowledge in hospital intensive care unit environments to support dosing within the narrow window between therapeutic failure and toxicity. Liquid chromatography-tandem mass spectrometry (LC-MS/MS) is the most suitable analytical technique for these drugs; however, clinicians, patients, and laboratories would benefit from shortening the timeframe between the collection of samples and reporting of results.

The authors developed a very rapid LC-MS/MS method for 9 β-lactam antimicrobial drugs on a commercial core-shell reverse-phase LC column by exploiting the performance of such stationary phase materials at a high mobile-phase linear velocity and using a simple flow split to optimize ionization conditions in the mass spectrometer ion source. The method's performance was assessed using a currently validated routine LC-MS/MS assay performed on the same instrument.

Routine ß-lactam assays were reduced from >6 minutes per sample tfor larger batch sizes and/or additional assays. The simple-to-implement technique demonstrated in this study may be applicable to other TDM assays or any LC-MS/MS method where faster turnaround times are desirable.
Dried blood spots (DBSs) are promising candidates for therapeutic drug monitoring. In this study, a simple method for the simultaneous measurement of tyrosine kinase inhibitors (TKIs), including bosutinib, dasatinib, ibrutinib, imatinib, nilotinib, and ponatinib, using DBS was developed and validated. The prediction of the plasma concentration of TKIs based on the TKI concentrations in the DBS was assessed using the developed measurement method.

DBS was prepared using venous blood on Whatman 903 cards. One whole DBS sample containing the equivalent of 40 μL of blood was used for the analysis. The analytical method was validated according to the relevant guidelines. For clinical validation, 96 clinical samples were analyzed. The regression equation was derived from a weighted Deming regression analysis, and correction factors for calculating the estimated plasma concentrations (EPCs) of the analytes from their concentrations in the DBS and the predictive performance of EPC were evaluated using 2 conversiong to the small clinical sample size, further clinical validation is needed to determine the predictive performance of EPCs for the 6 TKIs.
Escitalopram is metabolized by CYP2C19 to N-desmethyl escitalopram and escitalopram propionic acid. The primary aims of this study were to investigate the impact of the CYP2C19 phenotype on metabolic ratios of escitalopram in vivo and propose a biomarker for the CYP2C19 phenotype in patients treated with escitalopram.

Median steady-state serum metabolite/parent drug ratio of N-desmethyl escitalopram and escitalopram propionic acid was investigated across CYP2C19 genotype-translated phenotype groups. The receiver operator characteristics method and the area-under-the-receiver-operator-characteristics curve was used to determine the best suited metabolic ratio for detecting CYP2C19 poor metabolizers (PMs).

A total of 441 patients were included in the study. The N-desmethyl escitalopram/escitalopram ratio was 67% and 44% lower in CYP2C19 PMs and intermediate metabolizers (IMs), respectively, than normal metabolizers. Furthermore, the ability of the ratio to predict CYP2C19 PMs was 92%. A metabolic ratio ofscitalopram propionic acid/escitalopram ratio was also associated with CYP2C19 activity; however, the ratio was inferior to the DECT/ECT at predicting PMs.
The increased spectral dispersion achieved at ultra-high field permits quantification of γ-aminobutyric acid (GABA) concentrations at ultra-short-TE without editing. This work investigated the influence of spectral quality and different LCModel fitting approaches on quantification of GABA. Additionally, the sensitivity with which cross-sectional and longitudinal variations in GABA concentrations can be observed was characterized.

In - vivo spectra were acquired in the posterior cingulate cortex of 10 volunteers at 7T using a STEAM sequence. Synthetically altered spectra with different levels of GABA signals were used to investigate the reliability of GABA quantification with different LCModel fitting approaches and different realizations of SNR. The synthetically altered spectra were also used to characterize the sensitivity of GABA quantification.

The best LCModel fitting approach used stiff spline baseline, no soft constraints, and measured macromolecules in the basis set. CDK inhibitor With lower SNR, coefficients of variation increased dramatically. Longitudinal and cross-sectional variations in GABA of 10% could be detected with 79 and 48 participants per group, respectively. However, the small cohort may bias the calculation of the coefficients of variation and of the sample size that would be needed to detect variations in GABA.

Reliable quantification of normal and abnormal GABA concentrations was achieved for high quality 7T spectra using LCModel fitting.

Patients awaiting liver transplant are usually assessed for presence of dental foci to prevent bacterial infection post-transplant, but evidence to support dental examination and treatment is limited. We investigated if treatment of dental foci decreased bacterial infections before and after transplant.

Patients transplanted at the university hospital of Bonn were retrospectively assessed for occurrence of bacterial infections before and after transplant according to presence and treatment of dental foci.

35/110 patients showed good oral health, 39/110 patients received dental care and 36/110 patients did not receive dental care despite poor oral health. Patients with alcohol-associated liver disease presented with the highest rate of dental foci. Bleeding complications due to oral care occurred in five patients with poor coagulation. After transplant, the number of infections per patient was higher in patients with poor oral health (2.9) compared to patients after dental care (1.9) or with good oral health (1.8) (p=.02), with streptococcal infections being more frequent in patients with poor oral health. Before transplant, bacterial infections, in particular bacteraemia and spontaneous bacterial peritonitis, were also more common in patients with untreated dental foci. Streptococci and Staphylococci were more often detected in patients with dental foci. Dental treatment was associated with a reduction in bacterial infections.

Presence of dental foci is associated with an increased risk for bacterial infections not only after but also before liver transplant. Dental treatment might be a safe and effective procedure to mitigate this risk.

Evidence suggests that social support may be key to mitigating against adverse health impacts of such measures, particularly when such social support is identity-based. In this longitudinal study, we examined the role of social identity and perceived social support in mental and physical health outcomes during the COVID-19 pandemic. Participants completed a survey at 4 time points during the first year of the pandemic May/June 2020 (T1; N = 443); September/October 2020 (T2; N = 235); December 2020/January 2021 (T3; N = 243); and April 2021 (T4; N = 206). Results showed that at each time point, social support was predicted by identification with multiple groups before COVID-19, identity continuity, and identification with communities. Higher identity continuity and identification with communities both predicted greater mental and physical health at the same time point, mediated by perceived social support. Interestingly, higher identity continuity and identification with communities predicted higher social support at the same time point, which in turn predicted worse mental and physical health outcomes at the subsequent time point. Findings are discussed in relation to the context of the first year of the pandemic and the changing nature of societal restrictions across the four survey time points.
To report cerebrospinal fluid leak as an uncommon but noteworthy delayed complication after endoscopic orbital surgeries and to describe its incidence, mechanism, prevention, diagnosis, and management.

Case series of 3 patients who underwent endoscopic orbital surgery in the Department of Ophthalmology, Shanghai Ninth People's Hospital affiliated to Shanghai JiaoTong University School of Medicine from January 2003 to December 2020. A review of the literature was also conducted.

Three cases of delayed cerebrospinal fluid leaks occurred 10 years, 3 months, and 4 months after endoscopic orbital surgeries, respectively, were reviewed and reported. Two patients developed cerebrospinal fluid leaks after surgical repair of orbital blowout fractures with titanium mesh and porous polyethylene (Medpor), respectively, and 1 patient developed cerebrospinal fluid leak after transantral optic canal decompression. In the first case, head computed tomography (CT) cisternography and magnetic resonance imaging confirmed the site of the leak that required surgical repair.
