2 autopsy situations together with accidental injuries on the tummy pursuing cardiopulmonary resuscitation.
Pharmacogenomics is increasingly moving into mainstream clinical practice. Careful consideration must be paid to inclusion of diverse populations in research, translation and implementation, in the historical and social context of population stratification, to ensure that this leads to improvements in healthcare for all rather than increased health disparities. This review takes a broad and critical approach to the current role of diversity in pharmacogenomics and addresses potential pitfalls in order to raise awareness for prescribers. It also emphasizes evidence gaps and suggests approaches that may minimize negative consequences and promote health equality.
In 2019, the United States Food and Drug Administration detected above-regulation levels of the human carcinogen N-nitrosodimethylamine (NDMA) in ranitidine, resulting in a complete removal of the medication from the market. NDMA is known to cause gastrointestinal malignancies in animal models.

To determine if patients who were receiving ranitidine have a higher risk of developing cancers of the digestive tract compared to patients taking other anti-reflux medications.

Using the nationwide database IBM Explorys, patients taking ranitidine were compared to patients on either famotidine or omeprazole. Incidence data of new malignancies of the oesophagus, stomach, liver, pancreas, and colon/rectum were obtained in 1-year intervals for up to 10years. Two multivariable logistic regression models were used to calculate odds ratios (ORs), one adjusting for common risk factors for each cancer studied, and the other for demographic factors.

Patients on ranitidine who were compared to patients on famotidine had ORs of 0.51(95% CI 0.43-0.60), 0.43(95% CI 0.36-0.51), 0.39(95% CI 0.36-0.41), 0.54(95% CI 0.49-0.62), and 0.46(95% CI 0.43-0.49) of developing oesophageal, gastric, hepatocellular, pancreatic, and colorectal cancers, respectively (P<0.001). Patients on ranitidine compared to omeprazole had ORs of 0.62(95% CI 0.52-0.72), 0.58(95% CI 0.49-0.68), 0.81 (95% CI 0.76-0.86), 0.68(95% CI 0.60-0.76), and 0.66(95% CI 0.62-0.70) of developing oesophageal, gastric, hepatocellular, pancreatic, and colorectal cancers respectively (P<0.001).

Use of ranitidine was not associated with an increased odds of developing gastrointestinal malignancies compared to omeprazole or famotidine use.

It is a tetrameric complex of two COP1 and two SPA proteins. Both COP1 and SPA are essential for the activity of this complex, and they both contain a C-terminal WD-repeat domain responsible for substrate recruitment and binding of DDB1. Here, we used a WD domain swap-approach to address the cooperativity of COP1 and SPA proteins. We found that expression of a chimeric COP1 carrying the WD-repeat domain of SPA1 mostly complemented the cop1-4-mutant phenotype in darkness, indicating that the WD repeat of SPA1 can replace the WD repeat of COP1. In the light, SPA1-WD partially substituted for COP1-WD. In contrast, expression of a chimeric SPA1 protein carrying the WD repeat of COP1 did not rescue the spa-mutant phenotype. Together, our findings demonstrate that a SPA1-type WD repeat is essential for COP1/SPA activity, while a COP1-type WD is in part dispensible. Moreover, a complex with four SPA1-WDs is more active than a complex with only two SPA1-WDs. A homology model of SPA1-WD based on the crystal structure of COP1-WD uncovered two insertions and several amino acid substitutions at the predicted substrate-binding pocket of SPA1-WD.
To assess the use of Medicaid programs, including waivers, to address the needs of aging autistic individuals.

We gathered data on Medicaid programs in place between 2004 and 2015 for 50 states and the District of Columbia from the Centers for Medicare and Medicaid Services website, by contacting state Medicaid administrators and advocacy groups, and by reviewing the Medicaid Analytic eXtract Waiver Crosswalk.

This retrospective analysis classified each Medicaid program and documented state changes over time in eligibility criteria those serving autism spectrum disorder only, autism spectrum disorder or intellectual disability, and intellectual disability only.

We captured age and diagnosis eligibility criteria for Medicaid programs serving any of the three target groups.

A total of 269 Medicaid programs met our criteria and most programs (51%) were 1915(c) waivers. The number of autism-specific 1915(c) waivers grew more than fivefold during the study period, outpacing increases in waivers serving individuals with intellectual disability.

States varied in their use of Medicaid to address the needs of the aging autism population. Further study of characteristics of states that changed their Medicaid programs, and of the health care use and outcomes associated with these changes, are needed to identify opportunities to replicate effective approaches to meeting the needs of this population.

In the present study, the insoluble dietary fiber was extracted from defatted rice bran by enzymatic treatments (IDF-dRB), followed by investigation about the adsorption and antioxidant activities in vitro. Moreover, the alleviating effects of IDF-dRB on hyperlipidemia were evaluated and analyzed. As a result, IDF-dRB possessed good adsorption capacities of glucose and cholesterol, and also exhibited excellent properties in scavenging radicals. Furthermore, intervention with IDF-dRB significantly improved lipid and glucose metabolism and alleviated inflammation and oxidative stress in rats fed high-fat diet. It was also observed that IDF-dRB treatment could recover the decline in species of gut microbiota caused by high fat diet, increase the community richness, and modulate the metabolic function of gut microbiota. In conclusion, the results indicated that IDF-dRB could ameliorate hyperlipidemia from many aspects and offered some perspectives about the effects of diet intervention with insoluble dietary fiber. PRACTICAL APPLICATION Rice bran and defatted rice bran are coproducts in the rice processing industry and potentially valuable for the preparation of insoluble dietary fiber. Here an insoluble dietary fiber IDF-dRB was extracted from defatted rice bran and showed good properties in improving lipid and glucose levels, alleviating inflammation and oxidative stress, and modulating gut microbiota in rats fed high-fat diet, suggesting the potential application in ameliorating hyperlipidemia.
Many patients with myelodysplastic syndromes (MDS) receive red cell transfusions to relieve symptoms associated with anemia, with transfusions triggered by hemoglobin level. It is not known if patients' quality of life (QOL) improves after transfusion, nor if peri-transfusion QOL assessment (PTQA) can guide future transfusion decisions.

We conducted a prospective pilot study of adults with MDS at three centers. Participants, who had to have hemoglobin ≥7.5, completed an MDS-specific measure of QOL (the Quality of Life in Myelodysplasia Scale, [QUALMS]) 1 day before and 7 days after red cell transfusion. A report was sent to each patient and provider before the next transfusion opportunity, indicating whether there were clinically significant changes in QOL. We assessed the proportion of patients experiencing changes in QOL, and with a follow-up questionnaire, whether they perceived their PTQA data were used for future transfusion decisions.

From 2018 to 2020, 62 patients enrolled (mean age 73 years) and 37 completed both pre- and post-transfusion QOL assessments. Of these, 35% experienced a clinically significant increase in QUALMS score 7 days after transfusion; 46% no change; and 19% a decrease. Among those completing the follow-up questionnaire, 23% reported that PTQA results were discussed by their provider when considering repeat transfusion.

These data suggest PTQA is feasible for patients with MDS. Moreover, while helpful for some, for many others, red cell transfusion may not achieve its intended goal of improving QOL. PTQA offers a strategy to inform shared decision-making regarding red cell transfusion.

This study was undertaken to describe long-term clinical and developmental outcomes in pediatric refractory status epilepticus (RSE) and identify factors associated with new neurological deficits after RSE.

We performed retrospective analyses of prospectively collected observational data from June 2011 to March 2020 on pediatric patients with RSE. We analyzed clinical outcomes from at least 30days after RSE and, in a subanalysis, we assessed developmental outcomes and evaluated risk factors in previously normally developed patients.

Follow-up data on outcomes were available in 276 patients (56.5% males). The median (interquartile range [IQR]) follow-up duration was 1.6 (.9-2.7) years. The in-hospital mortality rate was 4% (16/403 patients), and 15 (5.4%) patients had died after hospital discharge. One hundred sixty-six (62.9%) patients had subsequent unprovoked seizures, and 44 (16.9%) patients had a repeated RSE episode. Among 116 patients with normal development before RSE, 42 of 107 (39.3%) patients RSE duration as a predictor.
Adults with sickle cell disease (SCD) on chronic transfusion therapy are exposed to a large volume of blood products, thus increasing their risk of transfusion-associated human immunodeficiency virus (HIV), hepatitis C (HCV), and hepatitis B (HBV).

We performed a systematic chart review of chronically transfused SCD subjects at the Johns Hopkins Sickle Cell Center for Adults between October 2014 and September 2019 to determine our Center's adherence to the 2014 National Heart, Lung and Blood Institute (NHLBI) SCD guidelines for annual screening for Transfusion Transmitted infections (TTI) and assessed HBV immunity and HBV vaccination rates.

The study included 85 subjects with a median age of 34 years (23-63); 52% were female. No subject received annual screening; 68 subjects (80%) were screened for HIV, 60 subjects (71%) for HCV and 53 subjects (62%) for HBV infections at least once in the study period. Of those screened, one patient was newly diagnosed with HCV infection, and none with HIV or HBV infection.
