Software Created To Help Find a Cure for a “Great Neglected Disease”

Published

on

For decades, scientists around the world have worked to develop a treatment for schistosomiasis, a debilitating water-born parasite that affects more than 200 million people worldwide.

To aid this research, Rahul Singh, professor of computer science at San Francisco State University, has developed software that solves the key challenge of quantitatively assessing the impact of a drug on the parasite. Singh and his team recently completed and made public the Quantal Dose Response Calculator (QDREC), software that analyzes images showing the effects of potential drugs on parasites and quantifies their effectiveness. A description of the software was published online in Bioinformatics (Oxford University Press) on Dec. 24, 2014.

QDREC is designed to streamline the screening stage of the drug-discovery process, during which possible drugs are first identified. Traditionally, after introducing a chemical compound to a parasite, a scientist is required to meticulously document and analyze changes.

The subjective and low-throughput nature of this process — requiring highly trained scientists to study, one by one, the effects of a potential drug — is one of the major barriers to breakthroughs, Singh said. “You are doomed to only a trickle of advancements,” he added.

“The thought came to my mind to try to use computational and algorithmic ideas to do something that humans can’t do yet, which is to automate the process of the parasites being exposed to the drug,” Singh said. “The biologist or chemist would capture images or videos of what happens to the parasite, then the computer would analyze the images automatically and, at the end of the process, the computer would come up with a single measurement that would quantify whether the compound is effective.”

For the past six years, Singh and his team of students have developed many of the algorithmic solutions that comprise QDREC. The software is now available for parasitologists, biologists and other drug developers around the world to use — free of charge — in the quest to find a cure for schistosomiasis.

Endemic in parts of Sub-Saharan Africa, South America and Southeast Asia, the parasite — which Singh describes as the cause of a “great neglected disease” — lives in fresh water and penetrates a person’s skin when they enter the water.

It can remain inside the body, reproducing, for decades. Symptoms, caused by the body’s reaction to the worms’ eggs, can include abdominal pain, liver enlargement and kidney damage. Children who are infected often develop learning difficulties.

Beyond causing physical pain and suffering, schistosomiasis creates an unfortunate domino effect, Singh explained. “Typically, poor people have to use water infected with this parasite, then they catch this debilitating disease, so it impacts them economically,” Singh said. “It’s a vicious circle of poverty, and it goes from bad to worse.”

While a drug, called praziquantel, does exist to treat the disease, Singh pointed out, using a single drug to treat millions of people across a large area over decades carries a high risk of the parasite building resistance. For that reason, the World Health Organization has designated the discovery of new therapies for schistosomiasis an urgent need.

Nonetheless, Singh said that the commercial drug discovery sector has typically neglected such diseases — even though they affect a large percentage of humankind — because most of the infected people are poor. “People who suffer from these diseases do not carry credit cards, so it would not fit the business models of pharmaceutical companies to try to pursue these diseases — they would not make enough money to recoup their research and development costs,” Singh said.

But Singh said that he is optimistic that QDREC will help make it possible to find an effective treatment for schistosomiasis. “This parasite has been studied since the 1800s, but until last month the kind of results obtainable with QDREC were not possible,” Singh said. “Now scientists can screen a large number of compounds, upload the data, press a button, and in a few moments they will have an answer as to which are efficacious — something that before could take months or years.”

Oakland Conducts Its Biennial ‘Point in Time’ Homelessness Count

Oakland, along with other cities in Alameda County, conducted their biennial ‘Point In Time’ census count on Feb. 1 to gain a thorough understanding of the size and dispersion of the homeless population in the region. The Point In Time (PIT) count is federally required by the Housing and Urban Development Department as a requirement to receive funding and resources to tackle homelessness in the area.

Oakland, along with other cities in Alameda County, conducted their biennial ‘Point In Time’ census count on Feb. 1 to gain a thorough understanding of the size and dispersion of the homeless population in the region.

The Point In Time (PIT) count is federally required by the Housing and Urban Development Department as a requirement to receive funding and resources to tackle homelessness in the area.

David Modersbach, Grants Manager of Alameda County Health Care for the Homeless program, said that the methodology this time around was different, as this count had a much more personal “lived experience” aspect that previous counts did not have.

In 2022, the county relied more on statistical extrapolation and assumptions, but this year’s survey questionnaires allowed for details on substance abuse issues, how long someone has been living without proper housing, what resources people are in need of and much more.

“[The PIT count is] a critical opportunity for the county, Continuum of Care, and cities to understand the magnitude of homelessness in Alameda County. [The count] enables us to better allocate resources and implement effective programs to tackle this issue head-on in a compassionate and inclusive way,” Modersbach said.

St. Mary’s Center was one of the many meeting hubs across the county that hosted volunteers and community officials the morning of the count. The organization has been deeply involved in the effort to provide resources for unhoused people and others in need.

St. Mary’s is a nonprofit in West Oakland that helps seniors and preschool families with food and housing. Last year, the organization helped about 50 seniors find housing after they had fallen on hard times.

Sharon Cornu, executive director of St. Mary’s, said a lot of the older couples and individuals that come into the center have borne the brunt of the skyrocketing cost of living in the Bay Area. The most recent influx of seniors St. Mary’s has seen coming in for help has been made up of people who were evicted when the COVID-19-related moratorium on rent payment ended.

“Seniors are the fastest growing segment of the unhoused and the incredibly high cost of housing is driving them to the streets,” Cornu said.

Among the volunteers were workers with Operation Dignity, a nonprofit organization that helps veterans and those living on the street find shelter, transitional housing and supportive services.

“These are our stomping grounds,” Ivan Magana, program manager for Operation Dignity said.

Magana stated that his team was extremely familiar with the people residing in the encampments they were conducting the count in since Operation Dignity made many visits to these areas while doing community outreach. He said they had even informed some of the unhoused people they knew about the count a few days prior so they would not be alarmed when the enumerators showed up early in the morning to conduct the count.

Not everyone got the memo though, as the volunteers encountered an almost violent situation around the 6 a.m.  when a young woman living in a bus yelled at the Operation Dignity workers to leave her alone.

Luckily, the three-year experience Mangana has working with Operation Dignity and his knowledge of therapeutic health services, equipped him with the techniques needed to deescalate the tension. The woman soon realized who the volunteers were and apologized, he said.

Another volunteer and Operation Dignity worker, Yolanda Kirkpatrick, noted that she was initially hesitant because of the early schedule. She felt the time deterred others from participating, too.

Her prediction would come true as the hours went on and they continued to walk along 24th St in downtown Oakland and there was very little activity on the streets.

The volunteers shared similar sentiments. Although the community the people they were engaging for the count and surveys encounter tend to distrust outsiders, the PIT count was necessary for the city to receive the appropriate level of federal funds to address a crisis that is spiraling out of control in California.

A full analysis and report of the count will be made available in the summer.

For Cervical Cancer Month, Medical Community Focused on Education

January was Cervical Cancer Awareness Month. Physicians, advocates and others in the medical community commemorated the month by raising awareness about a form of cancer they say is highly preventable and treatable. Cervical cancer is caused by a virus called the human papillomavirus (HPV) and it develops slowly over time but can be prevented with proper care in girls as young as 13 years old.

January was Cervical Cancer Awareness Month.

Physicians, advocates and others in the medical community commemorated the month by raising awareness about a form of cancer they say is highly preventable and treatable.

Cervical cancer is caused by a virus called the human papillomavirus (HPV) and it develops slowly over time but can be prevented with proper care in girls as young as 13 years old.

Sonia Ordonez, an OBGYN and gynecology surgeon at Kaiser Permanente, stated that as soon as people with cervixes reach the maturity reproductive age, they should start taking preventative measures like getting the HPV vaccine. The vaccine involves a series of two-doses for people aged 9 through 14 or three-doses for people 15 through 45 years old.

“I see a lot of young women who can’t remember or may not have gotten [the vaccine] when they were younger, or maybe got one, but we can give them the series of vaccines and restart at any point in time,” Ordonez said.

She said that cervical cancer is not the only cancer caused by HPV. Strains of the virus can also lead to throat, anal and penile cancers.

Screening is also an effective way to check for cervical cancer and should be done every three years after someone turns 21, doctors recommend. It is best to start as early as possible to catch occurrences early.

Ordonez said that this cancer is also more likely found in people of color and has led to more deaths overall.

A Mayo Clinic article published last month stated that Black women are more likely to be diagnosed and die of cervical cancer, compared to White women in the U.S.

2,000 Black women are diagnosed every year with cervical cancer and 40% die as a result.

“This disparity is not due to genetic differences among White, Black or Hispanic women, but rather related to systemic racism, access to healthcare and socioeconomic factors,” Dr. Olivia Cardenas-Trowers, a Mayo Clinic urogynecologist, said in the article.

Ordonez stated that immigrant women are also highly susceptible to the cancer, as many Latin American countries may not have accessibility to screenings or lack of insurance makes it harder for them to get tested.

Hispanic women are 40% more likely to be diagnosed with cervical cancer, and 30% more likely to die from it, as compared to non-Hispanic White women, according to the Office of Minority Health.

Family medicine physician, Joy Anyanwu, stated that the pandemic contributed to hesitancy about getting cervical cancer screenings among some women. Other factors are people’s aversion to vaccines, parents not wanting to believe that their children are or will become sexually active, and doubt about the overall effectiveness of the vaccine.

“The vaccine is very safe — over 97% effective in preventing cervical cancer,” Anyanwu said. “Even if you aren’t having sex, the earlier you start would actually help.”

Anyanwu said she understands that parents might not want to ask questions about their children’s reproductive health, but it’s a mindset that can be a barrier to having important conversation about prevention or care.

To keep families their families and communties healthy, the doctor emphasized that people should prioritize keeping up with their vaccine series and going to screenings every year.
