Helicobacter pylori is an important risk factor for gastric ulcers. However, antibacterial therapies increase the resistance rate and decrease the eradication rate of H. pylori. Inspired by the microaerophilic characteristics of H. pylori, we aimed at effectively establishing an oxygen-enriched environment to eradicate and prevent the recurrence of H. pylori. The effect and the mechanism of an oxygen-enriched environment in eradicating H. pylori and preventing the recurrence were explored in vitro and in vivo. During oral administration and after drug withdrawal, H. pylori counts were evaluated by Giemsa staining in animal cohorts. An oxygen-enriched environment in which H. pylori could not survive was successfully established by adding hydrogen peroxide into several solutions and rabbit gastric juice. Hydrogen peroxide effectively killed H. pylori in Columbia blood agar and special peptone broth. Minimum inhibition concentrations and minimum bactericidal concentrations of hydrogen peroxide were both relatively stable after promotion of resistance for 30 generations, indicating that hydrogen peroxide did not easily promote resistance in H. pylori. In models of Mongolian gerbils and Kunming mice, hydrogen peroxide has been shown to significantly eradicate and effectively prevent the recurrence of H. pylori without toxicity and damage to the gastric mucosa. The mechanism of hydrogen peroxide causing H. pylori death was related to the disruption of bacterial cell membranes. The oxygen-enriched environment achieved by hydrogen peroxide eradicates and prevents the recurrence of H. pylori by damaging bacterial cell membranes. Hydrogen peroxide thus provides an attractive candidate for anti-H. pylori treatment.

To obtain the optimal dosage regimen in patients receiving extracorporeal membrane oxygenation (ECMO), we developed a population pharmacokinetics model for cefpirome and performed pharmacodynamic analyses. This prospective study included 15 patients treated with cefpirome during ECMO. Blood samples were collected during ECMO (ECMO-ON) and after ECMO (ECMO-OFF) at predose and 0.5 to 1, 2 to 3, 4 to 6, 8 to 10, and 12 h after cefpirome administration. The population pharmacokinetic model was developed using nonlinear mixed effects modeling and stepwise covariate modeling. Monte Carlo simulation was used to assess the probability of target attainment (PTA) and cumulative fraction of response (CFR) according to the MIC distribution. Cefpirome pharmacokinetics were best described by a two-compartment model. Covariate analysis indicated that serum creatinine concentration (SCr) was negatively correlated with clearance, and the presence of ECMO increased clearance and the central volume of distribution. The simulations showed that patients with low SCr during ECMO-ON had lower PTA than patients with high SCr during ECMO-OFF; so, a higher dosage of cefpirome was required. Cefpirome of 2 g every 8 h for intravenous bolus injection or 2 g every 12 h for extended infusion over 4 h was recommended with normal kidney function receiving ECMO. We established a population pharmacokinetic model for cefpirome in patients with ECMO, and appropriate cefpirome dosage regimens were recommended. The impact of ECMO could be due to the change in patient status on consideration of the small population and uncertainty in covariate relationships. Dose optimization of cefpirome may improve treatment success and survival in patients receiving ECMO. (This study has been registered at ClinicalTrials.gov under identifier NCT02581280.)

There is an ongoing need for safe and effective anti-bedbug compounds. Here, we tested the toxicity of three antimicrobial agents against bedbugs when administered orally. We reveal that doxycycline has direct insecticidal activity at 250 μg/ml (0.025%) that is particularly strong against immature bedbugs and appears to be independent of antimicrobial activity. Future studies to determine the mechanisms behind this property could be useful for the development of orally active insecticides or anti-bedbug therapeutics.

Hydroxychloroquine, the much-touted, much-maligned drug initially championed by President Trump as a “game changer” against the coronavirus, but which was later shown to have potential risks to patients, is still being used to combat the pandemic in hospitals across the country.

A new study has found that hydroxychloroquine, an antimalarial drug recommended by President Trump as a possible treatment for coronavirus, does not help patients hospitalized with COVID-19, the disease caused by the virus.

We speak with Dr. Richard Levitan, an emergency physician based in Littleton, New Hampshire, who volunteered at Bellevue Hospital in Manhattan for 10 days at the height of the COVID-19 surge in April. Based on what he saw, he argues patients should be going to hospitals sooner and that medical professionals could use a small device you clip on your fingertip, called a pulse oximeter, to help detect the virus earlier by revealing oxygenation problems and elevated heart rates. "A pulse oximeter is just a measure of identifying how well the lungs are working, and, I believe, can be basically an early warning system in terms of patients to know who has COVID pneumonia," says Dr. Levitan.

A consignment of hydroxychloroquine from India has reached the US, the global COVID-19 hotspot, days after New Delhi lifted a ban on the export of the anti-malarial drug to America and some other countries on humanitarian grounds to help them combat the coronavirus pandemic.

More than 1.7 million people have tested positive and 108,867 people have died from the novel coronavirus globally. The US has emerged as the global hotspot with 20,580 deaths and nearly 530,000 cases, according to Johns Hopkins University data. America has replaced Italy as the country with the highest number of COVID-19 deaths at 20,597, the data shows.

Earlier this week, India at the request of President Donald Trump cleared the export of 35.82 lakh tablets of hydroxychloroquine to the US along with nine metric tons of active pharmaceutical ingredient or API required in the manufacturing of the drug.

"Supporting our partners in the fight against COVID-19. Consignment of hydroxychloroquine from India arrived at Newark airport today (Saturday)," India's Ambassador to the US Taranjit Singh Sandhu tweeted. Hydroxychloroquine has been identified by the US Food and Drug Administration as a possible treatment for the COVID-19 and it is being tested on more than 1,500 coronavirus patients in New York.

Anticipating that it will work, given the initial positive results, Trump has bought more than 29 million doses of hydroxychloroquine for potential treatment of COVID-19 patients. The arrival of consignment was welcomed by Americans.

"US will never forget this great humanitarian gesture by India. Under President Trump and Prime Minister Narendra Modi, the two largest democracies of the world have come together than ever in the past,' said New York-based Al Mason, a real estate consultant and a Trump supporter. "A wonderful gesture by India to its friends in need," tweeted Dr Sampat Shivangi.

Stay put: Indian students in US told

India's Ambassador to the US Taranjit Singh Sandhu has advised the Indian students, stranded in America due to the sudden closure of universities and the ongoing lockdown back home because of the coronavirus pandemic, to stay where they are and assured them help in this crisis situation. Sandhu addressed the concerns of over 500 Indian students who attended the Instagram Live session hosted by the Indian Embassy on Saturday. There are an estimated 250,000 Indian students in the US, a significantly large numbers of whom are stranded due to the sudden closer of the universities and asked to vacate their hostels and follow stay-at-home order issued by the authorities. The Indian government imposed a 21-day nationwide lockdown from March 24 to stem the tide of the fast-spreading disease and also suspended rail, road and air services during the period. "At this time the most advisable thing to do is stay where you are," Sandhu said.
