Are intelligent people more likely to get vaccinated? The association between COVID-19 vaccine adherence and cognitive profiles.

Introduction: Since vaccination adherence is crucial in reducing morbidity and mortality during a pandemic, we characterized the association between demographic, intelligence, and personal attributes and COVID-19 vaccination adherence among young adults.

Methods: Cohort study including vaccination data of 185,061 personnel, collected during 13 months of COVID-19 vaccination campaign, while a wide array of vaccination incentives were offered. The effect of demographic data (age, gender and socioeconomic status), military medical fitness - fit for combat service, administrative service, or unfit (volunteering), general intelligence score (GIS) and military social score (MSS) assessing social abilities, on vaccine adherence (allocating by IMOH guidelines) was examined.

Combined Presentation of Acute Confusion and Severe Pancytopenia in Vitamin B12 Deficiency.

Vitamin B12 deficiency is more prevalent in the elderly and can develop as a result of malnutrition, malabsorption, chronic alcoholism, and chronic use of common medications (e.g. metformin, PPI, methotrexate) along with other causes.

Statin-Induced Anti-3-Hydroxy-3-Methylglutaryl-Coenzyme A Reductase (Anti-HMGCR) Myopathy.

Statins are known to pharmacologically target 3-hydroxy-3-methylglutaryl-coenzyme A reductase (HMGCR). Several subtypes of anti-HMGCR autoimmune myopathies have been reported as a result of statin use. Although these types vary widely, a severe and rare form of statin-induced myopathy is immune-mediated necrotizing myopathy (IMNM), resulting in severe muscle injury that does not respond to statin cessation and is associated with poor outcomes.

Personalized microbiome-driven effects of non-nutritive sweeteners on human glucose tolerance.

Non-nutritive sweeteners (NNS) are commonly integrated into human diet and presumed to be inert; however, animal studies suggest that they may impact the microbiome and downstream glycemic responses. We causally assessed NNS impacts in humans and their microbiomes in a randomized-controlled trial encompassing 120 healthy adults, administered saccharin, sucralose, aspartame, and stevia sachets for 2 weeks in doses lower than the acceptable daily intake, compared with controls receiving sachet-contained vehicle glucose or no supplement. As groups, each administered NNS distinctly altered stool and oral microbiome and plasma metabolome, whereas saccharin and sucralose significantly impaired glycemic responses.

The Role of Paracellular Transport in the Intestinal Absorption and Biopharmaceutical Characterization of Minoxidil.

The purpose of this study was to evaluate mechanisms behind the intestinal permeability of minoxidil, with special emphasis on paracellular transport, and elucidate the suitability of minoxidil to be a reference drug for Biopharmaceutics Classification System (BCS). The permeability of minoxidil (vs. metoprolol) was evaluated in-silico, in-vitro using both the PAMPA assay and across Caco-2 cell monolayers, as well as in-vivo in rats throughout the entire intestine.

Introduction: The Israeli Defense Forces Medical Corps (IDF-MC) implemented the use of low-titer group O whole blood (LTOWB) as the first-choice resuscitation fluid in the IDF airborne Combat Search and Rescue Unit (IDF-CSAR) for aerial evacuation of both military and civilian casualties in June 2018 for injured patients with hemorrhagic shock and at least one of the following: systolic blood pressure <90 mm Hg, heart rate >130 beats/min, deterioration of consciousness without head injury or hemoglobin concentration ≤7 g/dL.

Method: All casualties treated with LTOWB by IDF-CSAR providers from June 2018 to January 2021 were included. Demographic and prehospital treatment data were collected in order to check compliance and adherence to the IDF-MC guidelines.

Optimized In Silico Modeling of Drug Absorption after Gastric Bypass: The Case of Metformin.

Bariatric surgery is an effective treatment for severe obesity and related comorbidities, such as type II diabetes. Gastric bypass surgery shortens the length of the intestine, possibly leading to altered drug absorption. Metformin, a first-line treatment for type II diabetes, has permeability-dependent drug absorption, which may be sensitive to intestinal anatomic changes during bypass surgery, including Roux-en-Y gastric bypass (RYGB).

Sub-cutaneous Pfizer/BioNTech COVID-19 vaccine administration results in seroconversion among young adults.

Route of vaccine administration plays a role in extent and quality of immunogenicity. 790 military personnel accidentally received the first of two doses of Pfizer/BioNTech mRNA anti Covid-19 vaccine using a needle intended for subcutaneous administration. A serological blood test (on day 21, prior to the second intramuscular dose) was performed, analyzing whether immunological response was elicited.

Background: This prospective study evaluated the effect of routine, uncontrolled, Israeli field storage conditions on the safety and efficacy of Lyo-Plas N Freeze-Dried Plasma (FDP) at the end of the manufacturer's shelf life, and up to 24 months post expiry. Clotting factors V, VIII and XI, proteins S, C, fibrinogen, PTT, ATIII, VWF, and INR as well as TEG, DDM, residual moisture, pH, and sterility of FDP returned from field units after uncontrolled storage were evaluated.

Study Design And Methods: Parameters measured at the end of manufacturer shelf life, as well as 6, 12, 18, and 24 months after expiry, were compared to those of freshly supplied FDP doses.

Stability of Diazepam Solution for Injection Following Long-Term Storage in an Ambient Temperature of the Mediterranean Climate.

Purpose: Diazepam is utilized as a convulsion antidote following nerve gas attacks. As an emergency medicine, it requires storage at ambient temperatures which often doesn't meet manufacturers' requirements, leading to an early invalidation of the product. Current work investigated this issue.

BCS Class IV Oral Drugs and Absorption Windows: Regional-Dependent Intestinal Permeability of Furosemide.

Biopharmaceutical classification system (BCS) class IV drugs (low-solubility low-permeability) are generally poor drug candidates, yet, ~5% of oral drugs on the market belong to this class. While solubility is often predictable, intestinal permeability is rather complicated and highly dependent on many biochemical/physiological parameters. In this work, we investigated the solubility/permeability of BCS class IV drug, furosemide, considering the complexity of the entire small intestine (SI).

The α7 nicotinic acetylcholine receptor agonist GTS-21 improves bacterial clearance in mice by restoring hyperoxia-compromised macrophage function.

Background: Mechanical ventilation, in combination with supraphysiological concentrations of oxygen (i.e., hyperoxia), is routinely used to treat patients with respiratory distress, such as COVID-19.

Biopharmaceutical characterization of rebamipide: The role of mucus binding in regional-dependent intestinal permeability.

In this study, we aimed to elucidate biopharmaceutical characteristics of the anti-ulcer drug rebamipide, with special emphasis on the influence of gastrointestinal (GI) mucus on rebamipide segmental-dependent permeability and absorption. Experimental studies and physiologically-based pharmacokinetic (GastroPlus) simulations were used to elucidate segmental-dependent absorption and pharmacokinetic (PK) profile, accounting for various drug properties, including solubility/dissolution limitations, regional-dependent drug affinity to mucus and membrane permeability, as well as physiological factors such as regional-pH differences along the intestine, thickness and types of mucus, transit time and surface areas. Low permeability and extensive binding to GI mucus were the key modeling features, and accounting for these resulted in good fitting between the predicted and in-vivo PK profiles, validating the ability of the model to pinpoint the underlying mechanisms of rebamipide limited oral bioavailability.

Segmental-Dependent Solubility and Permeability as Key Factors Guiding Controlled Release Drug Product Development.

The main factors influencing the absorption of orally administered drugs are solubility and permeability, which are location-dependent and may vary along the gastrointestinal tract (GIT). The purpose of this work was to investigate segmental-dependent intestinal absorption and its role in controlled-release (CR) drug product development. The solubility/dissolution and permeability of carvedilol (vs.

Methods And Materials: After reconstitution, clotting factor levels were compared to those of freshly supplied FDP doses.

Post-Antibiotic Gut Mucosal Microbiome Reconstitution Is Impaired by Probiotics and Improved by Autologous FMT.

Probiotics are widely prescribed for prevention of antibiotics-associated dysbiosis and related adverse effects. However, probiotic impact on post-antibiotic reconstitution of the gut mucosal host-microbiome niche remains elusive. We invasively examined the effects of multi-strain probiotics or autologous fecal microbiome transplantation (aFMT) on post-antibiotic reconstitution of the murine and human mucosal microbiome niche.

Personalized Gut Mucosal Colonization Resistance to Empiric Probiotics Is Associated with Unique Host and Microbiome Features.

Empiric probiotics are commonly consumed by healthy individuals as means of life quality improvement and disease prevention. However, evidence of probiotic gut mucosal colonization efficacy remains sparse and controversial. We metagenomically characterized the murine and human mucosal-associated gastrointestinal microbiome and found it to only partially correlate with stool microbiome.
