Cyclosporin A is a calcineurin inhibitor which has a narrow therapeutic window and high interindividual variability. Various population pharmacokinetic models have been reported; however, professional software and technical personnel were needed and the variables of the models were limited. Therefore, the aim of this study was to establish a model based on machine learning to predict CsA trough concentrations in Chinese allo-HSCT patients.
A total of 7874 cases of CsA therapeutic drug monitoring data from 2069 allo-HSCT patients were retrospectively included. Sequential forward selection was used to select variable subsets, and eight different algorithms were applied to establish the prediction model.
XGBoost exhibited the highest prediction ability. Except for the variables that were identified by previous studies, some rarely reported variables were found, such as norethindrone, WBC, PAB, and hCRP. The prediction accuracy within ±30% of the actual trough concentration was above 0.80, and the predictive ability of the models was demonstrated to be effective in external validation.
In this study, models based on machine learning technology were established to predict CsA levels 3-4days in advance during the early inpatient phase after HSCT. A new perspective for CsA clinical application is provided.

In recent years, there has been an increase in the awareness and detection of EIB in elite athletes. This narrative review aims to evaluate the risk, prevention, diagnosis, medication, and anti-doping policies of EIB in elite athletes, and to provide more references for athletes with EIB. The results showed that athletes of endurance, winter, and water sports generally have a higher prevalence of EIB than athletes of other sports. Adaptive warm-up before formal exercise and using heat exchange masks at low temperatures are effective ways for athletes to prevent EIB. find more For physicians, the exercise challenge test and eucapnic voluntary hyperpnea are the recommended diagnostic methods for EIB in athletes. The treatment of athletes with EIB is medication-based, such as inhaled corticosteroids and beta-2 agonists, but current anti-doping policies should be considered when used.
Staphylococcus aureus bacteremia (SAB) disproportionately affects Black patients. The reasons for this disparity are unclear.
We evaluated a prospectively ascertained cohort of patients with SAB from 1995 to 2020. Clinical characteristics, bacterial genotypes, and outcome were compared among Black and White patients with SAB. Multivariable logistic regression models were used to determine factors independently associated with the outcomes.
Among 3068 patients with SAB, 1107 (36%) were Black. Black patients were younger (Median 56 years vs. 63 years; p < 0.001), had higher rates of diabetes (47.5% vs. 34.5%; p < 0.001), hemodialysis dependence (40.0% vs. 7.3%; p < 0.001), and HIV (6.4% vs. 0.6%; p < 0.001). Black patients had higher rates of methicillin-resistant S. aureus (49.3% vs 44.9%; p = 0.020), including the USA300 hypervirulent clone (11.5% vs. 8.4%; p = 0.007). White patients had higher rates of corticosteroid use (22.4% vs. 15.8%; p < 0.0001), and surgery in the preceding 30 days (28.1% vs. 18.7%; p < 0.001). Although median Acute Physiology Score (APS) at the time of initial SAB diagnosis was significantly higher in Black patients (Median APS 9, Interquartile Range [IQR] 5-14; vs. Median APS 7, IQR 4-12; p < 0.001), race was not associated with 90-day mortality (risk ratio (RR) 1.02; 95% CI 0.93-1.12, and rates of metastatic infection were lower among Black patients (37.2% vs. 41.3% White; p = 0.029).
Despite differences in Black patients' higher APS on presentation and more risk factors, including a 5 times higher risk of hemodialysis dependence, 90-day mortality among Black and White patients with SAB was similar.

Superior labrum anterior posterior (SLAP) tears can cause shoulder pain, disability, instability, and humeral head translation. YouTube has become an increasingly popular source of medical information, but little is currently known in terms of quality control of the uploaded content. The purpose of this study was to assess the quality of YouTube videos related to the diagnosis and treatment of Superior Labrum Anterior Posterior (SLAP) tears.
YouTube was queried in August 2021 using the two predetermined keywords 'SLAP tear' and 'superior labral tear.' The first 50 videos were analyzed by two independent reviewers and scored using 3 scoring systems Global Quality Scale (GQS), the Journal of the American Medical Association (JAMA), and the Shoulder-Specific Score (SSS) to determine video accuracy and reliability. Title, number of views, video duration, video source, content type, views/day, number of likes, number of dislikes, days since upload, like ratio (Like × 100/ [Like + Dislike]) and Video Power Indeviews.
YouTube videos on the diagnosis and management of SLAP tears have low overall quality and reliability scores. Independent physician and academic institution sources received higher mean scores for JAMA, GQS, and SSS. Video quality was not correlated with number of views.
Circulating individual SFAs in pregnant females are critical for maternal and fetal health. However, research on identifying their modifiable factors is limited.
We aimed to examine the associations of total physical activity (PA) and types of PA with circulating individual SFAs during pregnancy in a multiracial/multiethnic cohort of pregnant females in the United States.
The study included participants in a nested case-control study (n=321) from the Eunice Kennedy Shriver NICHD Fetal Growth Studies-Singleton Cohort. Sampling weights were applied, so the results represented the entire Fetal Growth Cohort. Plasma phospholipid SFAs were measured at 4 visits [10-14 (visit 1), 15-26 (visit 2), 23-31 (visit 3), and 33-39 (visit 4) weeks of gestation] throughout pregnancy. PA of the previous year at visit 1 and since the previous visit at the subsequent visits was assessed using the validated Pregnancy PA Questionnaire. Time-specific and longitudinal associations were examined using multivariable linear and gvely associated with circulating pentadecanoic and heptadecanoic acids. The findings warrant confirmation by future studies.This trial was registered at clinicaltrials.gov as NCT00912132.
Adrenal 11-oxygenated androgens may support cancer progression in men with prostate cancer owing to their abundance and androgenic potential. We hypothesized that preoperative circulating levels of 11-oxygenated androgens influence clinical outcomes in men with newly diagnosed localized prostate cancer.
We studied 1,793 treatment-naïve patients and 155 patients who received preoperative treatment with 5α-reductase inhibitors in the prospective PROCURE cohort, for which preoperative plasma samples were obtained prior to radical prostatectomy. Adrenal 11-oxygenated precursors, potent 11-oxygenated androgens and their metabolites (n=7), were quantified using liquid chromatography-tandem mass spectrometry. Circulating levels were evaluated in relation to prognostic factors, disease-free survival, and metastasis-free survival using multivariable Cox proportional hazards models.
At a median follow-up of 93.8 months after surgery, 583 patients experienced biochemical recurrence, 104 developed metastatic diseash metastasis-free survival in men with localized prostate cancer undergoing radical prostatectomy and are affected by 5α-reductase inhibitor treatment.Previously, a Saccharomyces cerevisiae fermentation product (SCFP) was shown to positively alter fecal microbiota, fecal metabolites, oxidative stress, and circulating immune cell function of adult dogs. The objective of this study was to measure the effects of SCFP on fecal characteristics, serum oxidative stress biomarkers, and whole blood gene expression of dogs undergoing transport stress. Sixteen adult pointer dogs [8M, 8F; mean age = 6.7 ± 2.1 yr; mean body weight (BW) = 25.5 ± 3.9 kg] were used in a randomized crossover design study. All dogs were fed a control diet for 4 wk, then randomly assigned to a control or SCFP-supplemented diet (formulated to include approximately 0.13% of the active SCFP ingredient) and fed to maintain BW for 11 wk. A 6-wk washout preceded the second 11-wk experimental period with dogs receiving opposite treatments. After 11 wk, fresh fecal and blood samples were collected before and after transport in a van for 45 min. Change from baseline data (i.e., before and after transpport stress. These data suggest that the benefits of feeding a SCFP during transport stress may be mediated through suppression of innate immune cell activation.Body size is arguably one of the most important traits influencing the physiology and ecology of animals. Shifts in animal body size have been observed in response to climate change, including in bumble bees (Bombus spp. [Hymenoptera Apidae]). Bumble bee size shifts have occurred concurrently with the precipitous population declines of several species, which appear to be related, in part, to their size. Body size variation is central to the ecology of bumble bees, from their social organization to the pollination services they provide to plants. If bumble bee size is shifted or constrained, there may be consequences for the pollination services they provide and for our ability to predict their responses to global change. Yet, there are still many aspects of the breadth and role of bumble bee body size variation that require more study. To this end, we review the current evidence of the ecological drivers of size variation in bumble bees and the consequences of that variation on bumble bee fitness, foraging, and species interactions. In total we review (1) the proximate determinants and physiological consequences of size variation in bumble bees; (2) the environmental drivers and ecological consequences of size variation; and (3) synthesize our understanding of size variation in predicting how bumble bees will respond to future changes in climate and land use. As global change intensifies, a better understanding of the factors influencing the size distributions of bumble bees, and the consequences of those distributions, will allow us to better predict future responses of these pollinators.
Determining the diagnostic accuracy of "exclusion" tests for primary aldosteronism (PA) compared to the aldosterone to renin ratio (ARR) is fundamental to avoid invasive subtyping in false-positive patients at screening.
To assess the accuracy of exclusion tests for PA using the diagnosis of unilateral PA as reference.
PubMed, EMBASE, Web of Science, and Cochrane Library databases were searched for studies published from January 1, 1970, to December 31, 2021, meeting tight quality criteria. Data were extracted following the PRISMA methodology. We performed a two-stage meta-analysis that entailed an exploratory and a validation phase based on a "golden" or "gold" diagnostic standard, respectively. Pooled specificity, negative likelihood ratio, diagnostic odds ratio, and summary area under the ROC curve (sAUROC) were calculated to analyze the accuracy of exclusion tests.
A meta-analysis of 31 datasets comprising a total of 4242 patients fulfilling the predefined inclusion criteria found that pooled accuracy estimates (sAUROC) did not differ between the ARR (0.
