Ranitidine (Zantac) recall expanded, many questions remain

As anticipated, recall of the popular heartburn medicine ranitidine (Zantac) has expanded. But we still have more questions than answers. As I mentioned in my original blog post on this topic, the online pharmacy Valisure, which originally alerted the FDA to the issue, found what they called “extremely high levels” of the probable cancer-causing substance N-nitrosodimethylamine (NDMA) in ranitidine products. The FDA has indicated that its own preliminary testing has detected low levels of NDMA in ranitidine. Testing methods may have influenced NMDA results The FDA has clarified that the testing method that found the “extremely high levels” of NDMA applied high heat, at a level much higher than normal body temperature. In other words, the testing did not reflect typical conditions under which the medication would be stored or taken. The FDA is asking all companies that manufacture ranitidine, as well as other similar medications (both H2 blockers, the class of drugs to which ranitidine belongs, and proton-pump inhibitors, or PPIs, a different class of drugs used for similar conditions), to test their products using lower heat closer to normal body temperature. So far, there is no indication that these other products are affected; the FDA is likely asking for these tests only as a precaution. As of now, the FDA has allowed ranitidine to remain on the market. Still, some manufacturers have issued voluntary recalls and some pharmacies have pulled it o...

tro V Abstract Immunotherapy has been showed as a promisor treatment, in special for hematological diseases. Chimeric antigen receptor T cells (CARs) which are showing satisfactory results in early-phase cancer clinical trials can be highlighted. However, preclinical models are critical steps prior to clinical trial. In this way, a well-established preclinical model is an important key in order to confirm the proof of principle. For this purpose, in this chapter will be pointed the methods to generate tumor cells expressing firefly Luciferase. In turn, these modified cells will be used to create a subcutaneous and...

Abstract Chimeric antigen receptor (CAR) T cell therapies are ex vivo manufactured cellular products that have been useful in the treatment of blood cancers and solid tumors. The quality of the final cellular product is influenced by several amenable factors during the manufacturing process. This review discusses several of the influences on cell product phenotype, including the raw starting material, methods of activation and transduction, and culture supplementation.

m KCR Abstract CAR-T cell immunotherapy is a promising therapeutic modality for cancer patients. The success of CAR-T cell therapy has been associated with the phenotype, activation and functional profiling of infused CAR-T cells. Therefore, immunophenotypic characterization of CAR-T cells during bioprocess is crucial for cell quality control and ultimately for improved antitumor efficacy. In this chapter, we propose a flow cytometry panel to characterize the immunophenotype of the CAR-T subsets. PMID: 31707677 [PubMed - in process]

It’s no exaggeration to say that lives are transformed by the Wheat Belly lifestyle. Look what happened to Susanne after her health was ruined by being gluten-free, reversed by following the Wheat Belly 10-Day Grain Detox. Food manufacturers, out of ignorance or ruthless profiteering, have chosen to replace wheat and gluten with cornstarch, rice flour, tapioca starch, or potato starch—among the few foods that provoke high blood sugar and insulin more than even our favorite grain to bash, wheat. It means that people who are gluten-free and consume such garbage replacement products gain weight in visceral inflamm...

Conclusion This larger set of observational data finds that PPI drugs are associated with an increase in the risk of early death compared with either H2 blockers or no acid suppression drugs. This was the case for participants both with and without gastrointestinal problems. It also appears as though the longer the PPIs drugs are taken, the greater the risk of death. Considering that these drugs are widely used in the UK, these findings may cause concern. But the research has a number of important limitations: The study was conducted in a population of mostly white, older US male veterans, which might limit the abi...

Conclusion This study has found that while overall gluten consumption in people without coeliac disease may not be related to heart disease risk, avoiding whole grains (wheat, barley and rye) in order to avoid gluten may be associated with increased heart disease risk. This study has several strengths, including its large size, the fact that data was collected prospectively and diet assessed at several time-points, the long period of follow up, and that it took into account a wide range of potential confounders. As with all studies of this type, it is possible that other factors may affect the results. However, the researc...

BackgroundPancreatic ductal adenocarcinoma (PDAC) is usually diagnosed in late adulthood; therefore, many patients suffer or have suffered from other diseases. Identifying disease patterns associated with PDAC risk may enable a better characterization of high-risk patients.MethodsMultimorbidity patterns (MPs) were assessed from 17 self-reported conditions using hierarchical clustering, principal component, and factor analyses in 1705 PDAC cases and 1084 controls from a European population. Their association with PDAC was evaluated using adjusted logistic regression models. Time since diagnosis of morbidities to PDAC diagno...

Conclusion Hyperexcitability of T5 and T6 sympathetic preganglionic fibers appears to be the main etiology of LPR. SNEPI can reduce LES relaxation and improve blood flow to the mucosa, thereby increasing the stability of the vagus reflex and laryngopharyngeal mucosal defense factors. To the best of our knowledge, this case represents the first report of a patient with LPR refractory to PPIs who was successfully treated with SNEPI alone. SNEPI can be considered as an alternative to anti-reflux procedures. References 1. Vakil N, van Zanten SV, Kahrilas P, et al. Global Consensus Group. The Montreal definition and classificat...
