There was also substantial variability in the methods used to develop PGSs, with between 3 and 6.6 million variants included in the PGSs. Finally, we observed significant inconsistencies in the reporting of PGS analyses and results, particularly in terms of risk model development and application, coupled with a lack of data transparency and availability, with only three pharmacogenomics PGSs deposited on the Polygenic Score Catalog. These findings highlight current gaps and key areas for future pharmacogenomic PGS research.Prevalence of osteoporosis is more than 50% in older adults, yet current clinical methods for diagnosis that rely on areal bone mineral density (aBMD) fail to detect most individuals who have a fragility fracture. Bone fragility can manifest in different forms, and a "one-size-fits-all" approach to diagnosis and management of osteoporosis may not be suitable. High-resolution peripheral quantitative computed tomography (HR-pQCT) provides additive information by capturing information about volumetric density and microarchitecture, but interpretation is challenging because of the complex interactions between the numerous properties measured. In this study, we propose that there are common combinations of bone properties, referred to as phenotypes, that are predisposed to different levels of fracture risk. Using HR-pQCT data from a multinational cohort (n = 5873, 71% female) between 40 and 96 years of age, we employed fuzzy c-means clustering, an unsupervised machine-learning method, to identify phenotypes of bonenotypes that capture key features of bone deterioration that are not distinguishable by aBMD. © 2021 American Society for Bone and Mineral Research (ASBMR).This article is a highlight of the paper by Ivanic and Schnermann et al. in this issue of Photochemistry and Photobiology (Daly et al. Photochem. Photobiol. 2022). The collaborative team utilized computational approaches to investigate the influence of electron-withdrawing groups at the 10' position of tetramethylrhodamine (TMR). Leveraging this information, the team was able to extend the emission of the TMR scaffold into the shortwave-infrared region (SWIR, 1000-2500 nm) by incorporation of a ketone functional group at the 10' position (Daly et al. Photochem. Photobiol. 2022). This work provides the first example of a TMR derivative with peak SWIR emission (λabs 862 nm, λem 1058 nm). The authors utilize the ketone rhodamine scaffold to generate fluorogenic, pH-responsive reporters. This work demonstrates the potential of the classic xanthene scaffold for use as a SWIR reporter, an important step in the ultimate expansion of the repertoire of small-molecule organic fluorophore scaffolds available for deep-tissue imaging applications.Photosynthetic bacteria can be useful biotechnological tools-they produce a variety of valuable products, including high purity hydrogen, and can simultaneously treat recalcitrant wastewaters. However, while photobioreactors have been designed and modeled for photosynthetic algae and cyanobacteria, there has been less work on understanding the effect of light in photosynthetic bacterial fermentations. To design photobioreactors, and processes using these organisms, robust models of light penetration, utilization, and conversion are needed. This stydy uses experimental data from a tubular photobioreactor designed to focus in on light intensity effects, to model the effect of light intensity on the growth of Rhodopseudomonas palustris, a model photosynthetic bacterium. The work demonstrates that growth is controlled by light intensity, and that this organism does experience photolimitation below 200 W/m2 and photoinhibition above 600 W/m2 . This has implications for outdoor applications, as there will be low growth during the periods of limited light, and growth may be inhibited during the light intensive hours of mid-day. Further, the work presents a model for light penetration in cylindrical photobioreactors, which tends to be the most common geometry. The model developed showed good fit to the experimental data for each light intensity investigated, with high R2 values and NRMSE values all below 20%. CP-690550 cell line The work extends the modeling tools for these organisms, and will allow for better photobioreactor design, and the integration of modeling tools in designing processes which use photosynthetic bacteria.We present a case of a 15-year-old female who was admitted in a comatose state with no spontaneous respiratory effort and absence of brainstem reflexes after cyclobenzaprine ingestion. Due to severe presentation and recent ingestion of high plasma protein binding medication with long half-life, therapeutic plasma exchange (TPE) was performed and resulted in full neurological recovery. This case explores the role of TPE as an effective treatment option for life-threatening cyclobenzaprine overdose. TPE is generally beneficial for drugs that have a low volume of distribution and high plasma protein binding. Cyclobenzaprine is known to have a relatively high volume of distribution. However, in the case of drug intoxication with relatively high-volume distribution, high protein binding, and long half-life, TPE could be effective if it is conducted promptly.Transition of rapid, ready-to-use, and low-cost nucleic acid-based detection technologies from laboratories to points of sample collection has drastically accelerated. However, most of these approaches are still incapable of diagnosis starting from sampling through nucleic acid isolation and detection in the field. Here we developed a simple, portable, low-cost, colorimetric, and remotely controllable platform for reliable, high-throughput, and rapid diagnosis using loop-mediated isothermal amplification (LAMP) assays. It consists of a thermally isolated cup, low-cost electronic components, a polydimethylsiloxane sample well, and a fast prototyped case that covers electronic components. The steady-state temperature error of the system is less then 1%. We performed LAMP, Colony-LAMP, and Colony polymerase chain reactions (PCRs) using the yaiO2 primer set for Escherichia coli and Pseudomonas aeruginosa samples at 65°C and 30 min. We detected the end-point colorimetric readouts by the naked eye under day light. We confirmed the specificity and sensitivity of our approach using pure genomic DNA and crude bacterial colonies. We benchmarked our Colony-LAMP detection against Colony PCR. The number of samples tested can easily be modified for higher throughput in our system. We strongly believe that our platform can greatly contribute rapid and reliable diagnosis in versatile operational environments.
Some guidelines allow for the use of either insulin or noninsulin antidiabetic agents for gestational diabetes, but only insulin is recommended for pregnant women with preexisting type 2 diabetes mellitus (T2DM). We aimed to document treatment patterns in routine care for women with preexisting T2DM.
We identified pregnancy cohorts within 2 US claims databases for publicly and privately insured individuals the Medicaid Analytical eXtract (2000-2014) and OptumClinformatics (2004-2014). T2DM was classified with a validated algorithm using ICD-9-CM and CPT codes. We assessed medication usage over the years of the study, and changes in medication use before and after the beginning of pregnancy, using prescription fills as a proxy for the use of insulin, metformin, sulphonylureas and other noninsulin antidiabetic agents before pregnancy and during each trimester.
Among 12,631 women with T2DM, insulin use in pregnancy was stable over the study years (55%-60% in the 2nd trimester), but 2nd trimester use of metformin increased from <5% to 20%. Over the study period, 41% of women filled a prescription for metformin before pregnancy, 37% in the 1st trimester and 17% in the 2nd trimester. By the 2nd trimester, few women used sulphonylureas (11%) or other noninsulin antidiabetic agents (1%). link2 Of the women on metformin only before pregnancy, 36% switched to insulin only by 2nd trimester, 11% added insulin and 16% continued on metformin only. Of the women on metformin and insulin before pregnancy, 61% switched to insulin only by 2nd trimester, 22% continued with metformin and insulin and <5% used only metformin.
The use of insulin-metformin combinations and other noninsulin antidiabetic drugs during pregnancy has increased. Safety studies for these medication regimens are needed.

Spina bifida is the most common neural tube defect. It has been associated with increased mortality, disability, and may require lifelong medical care. Higher-level lesions have been shown to be associated with increased mortality in infants with spina bifida.
A study was conducted using data from infants with myelomeningocele and related spina bifida reported to the New York State Birth Defects Registry for birth years 2008 through 2017. Descriptive statistics were conducted. Cox regression was used to calculate adjusted hazard ratios for mortality by age one, by lesion level. Hazard ratios were adjusted for birthweight and maternal race/ethnicity.
Overall survival at age one was 90.7%. link3 Cervical-level lesions had an increased risk of mortality compared to lumbar-level lesions (HR 8.32; 95% CI 2.56, 27.05). No statistically significant associations were found for sacral-level lesions compared to lumbar-level lesions.
These results suggest that infants with cervical-level spina bifida have a higher risk of death by age one than those with other lesion levels.

SMAD6 variants have been reported in patients with radioulnar synostosis (RUS). This study aimed to investigate the genotypes and phenotypes for a large cohort of patients with RUS having mutant SMAD6.
Genomic DNA samples were isolated from 251 RUS sporadic patients (with their parents) and 27 RUS pedigrees. Sanger sequencing was performed for the SMAD6 coding regions. For positive probands, co-segregation and parental-origin analysis of SMAD6 variants and phenotypic re-evaluation were performed for their family members.
We identified 50 RUS probands with SMAD6 variants (13 co-segregated with RUS in pedigrees and 37 in RUS-sporadic patients). Based on the new and previous data, we identified SMAD6 mutated in 16/38 RUS pedigrees and 61/393 RUS sporadic patients, respectively. Overall, 93 SMAD6 mutant patients with RUS were identified, among which 29 patients had unilateral RUS, where the left side was more involved than the right side (leftright=209). Female protective effects and non-full penetrance were observed, in which only 6.90% mothers (vs. ~50% fathers) of SMAD6 mutant RUS probands had RUS. Pleiotropy was observed as a re-evaluation of SMAD6 mutant families identified (a) three families had axial skeletal malformations; (b) two families had polydactyly; and (c) eight families had other known malformations.
SMAD6 was mutated in 42.11% RUS pedigrees and 15.52% RUS sporadic patients. The RUS patients with SMAD6 variants exhibit both non-full-penetrance, variable expressivity, pleiotropy, female protective effects, and the left side is more susceptible than the right side.
