An interdisciplinary study led by researchers at the University of South Florida and Indiana University has uncovered significant findings on the long-term effects of one of the most common forms of chemotherapy on cancer survivors.

Published in JAMA Oncology, the study tracked a cohort of testicular cancer survivors who received cisplatin-based chemotherapy. The team followed the patients for an average of 14 years, revealing that 78% experience significant difficulties in everyday listening situations, negatively impacting their quality of life. This collaborative research is the first to measure real-world listening challenges and hearing loss progression in cancer survivors over a long period of time.

“It’s important that we understand the real-world effects of patients’ sensory problems and if we can understand that, then we can develop better therapeutic strategies and preventive measures to improve the long-term quality of life for cancer survivors,” said Robert Frisina, distinguished university professor and chair of the USF Department of Medical Engineering.

Cisplatin is commonly used in chemotherapy treatments for a variety of cancers, including bladder, lung, neck and testicular. It is administered intravenously and affects various parts of the body. However, the ears are particularly vulnerable as they have little ability to filter out the drug, causing it to become trapped. This leads to inflammation and the destruction of sensory cells that are critical for coding sound, causing permanent hearing loss that can progressively get worse well after cisplatin treatments are completed.

Lead author Victoria Sanchez, associate professor in the USF Health Department of Otolaryngology Head & Neck Surgery, said that despite the known risks, there’s a nationwide lack of routine hearing assessments for patients undergoing chemotherapy. “Most patients still do not get their hearing tested prior to, during or after chemotherapy. Our study highlights the need for regular auditory evaluations to manage and mitigate long-term hearing damage.”

The research team found higher doses of cisplatin led to more severe and progressing hearing loss, especially in patients with risk factors, such as high blood pressure and poor cardiovascular health. They also experienced increased difficulty hearing in common environments, such as a loud restaurant.

“It will be critically important to follow these patients for life. Their current median age is only 48 years, and eventually they will enter the years at which age-related hearing loss also begins to develop,” said Dr. Lois B. Travis, Lawrence H. Einhorn Professor of Cancer Research at Indiana University School of Medicine and a researcher at the IU Melvin and Bren Simon Comprehensive Cancer Center. This research is part of The Platinum Study, an ongoing research effort led by Dr. Travis and funded by the National Cancer Institute to study cisplatin-treated testicular cancer survivors.

The hope is that this study will inspire further investigation into alternative chemotherapeutic protocols and preventive measures, such as FDA-approved drugs to prevent or reduce hearing loss.

“This research gives oncologists the information they need to explore alternative treatment plans that could reduce the long-term side effects, such as altering the dosages and timing of the cisplatin in the treatment, when that could be an appropriate option,” Frisina said.

Innovative solutions, such as Pedmark, a new FDA-approved injection that mitigates cisplatin-induced hearing loss in children, represent promising steps forward, according to Frisina.

“We want to protect our hearing or treat a hearing loss if hearing damage occurs,” Sanchez said. “Hearing allows us to connect to the world we love. Staying connected through conversations with family and friends, enjoyment of music and entertainment, staying safe and finding pleasure in our vibrant surroundings. Promoting optimal hearing for overall wellness is essential for healthy living.”

According to the American Cancer Society, in addition to cisplatin, other platinum chemotherapy drugs, such as carboplatin, cause damage to the cochlea in the inner ear and lead to hearing loss. The risk of damage is greater with higher doses of chemotherapy.

Building a Culture of Wellness by Fostering a Healthy and Financially Secure Workforce

Celebrating Corporate Wellness Awareness Week by highlighting the vital role that companies play in fostering employee health and well-being is not just a matter of timing; it’s a matter of necessity. A healthy workforce is a productive workforce, and a focus on wellness goes beyond just physical health.

This is particularly relevant given that the magnitude of medical expenses has shifted over the years. While common illnesses like influenza pose a threat, the bigger concern lies in hospital stays and unexpected medical procedures. These events can leave employees with significant financial burdens, impacting their well-being and productivity.

The role of employers in mitigating costs

While encouraging healthy lifestyles through fitness programmes and mental health support is vital, ensuring financial security in the face of unforeseen medical expenses is equally important. Employers play a significant role in ensuring their workforce has access to adequate healthcare. Traditionally, medical aid cover has been a common employment benefit, but rising costs have made it less affordable for some employers and their employees. Nevertheless, employers can still help by offering their people assistance through:

  • Understanding medical aid options: A knowledgeable broker can guide employers through the complexities of medical aid options. This includes explaining the benefits, limitations, and potential shortfalls associated with each plan.
  • Considering primary healthcare: For employees who cannot afford comprehensive medical aid, primary healthcare plans are short-term insurance products that offer access to doctors, specialists, and medication, often with capped benefits for private hospital visits.
  • Offering gap cover: Gap cover bridges the gap between medical aid payouts and the actual costs charged by specialists and hospitals, acting as a financial safety net to provide peace of mind for employees facing unforeseen medical expenses.

Common unforeseen medical expenses

  • Hospital stays: These can be particularly expensive, with costs varying depending on the condition and treatment required.
  • Specialist charges: Specialists often charge above the rates covered by medical aid plans, leaving patients with significant bills.
  • Emergency room visits: Even a seemingly minor trip to the ER can result in a hefty bill.

Addressing misconceptions about medical aid

Many employees believe that medical aid offers complete coverage. Brokers can help dispel this myth by explaining the intricacies of the available plan options, such as co-payments, network restrictions, and shortfalls. Some plans limit coverage to specific hospitals or providers, and employees need to be aware of these restrictions to avoid surprise costs, while certain medical aid plans require co-payments for specific procedures or medications, leaving employees with out-of-pocket expenses. Even with medical aid, specialists’ fees often exceed the amount reimbursed and gap cover addresses these shortfalls.

Financial security boosts workplace wellness

By offering (and even subsidising) a combination of medical aid, primary healthcare options, and gap cover, employers can significantly improve the well-being of their people. This is because financial security in the face of medical emergencies will reduce stress and boost morale. Employees with peace of mind regarding healthcare costs are more likely to be happy, productive, and less prone to absenteeism.

However, such assistance is more than simply offering access to such benefits. Employers need to ensure that their workforce can make informed decisions about the healthcare benefits available to them by partnering with a qualified broker. The broker can fulfil a vital educational role by conducting informative workshops to explain medical aid options and limitations and advocate for the value of gap cover.

It makes business sense to invest in a healthy workforce

By prioritising a holistic approach to employee wellness that encompasses both physical and financial health, companies can create a thriving workplace environment. Offering a more comprehensive benefits package that includes access to gap cover demonstrates a commitment to employee well-being, ultimately leading to a happier, healthier, and more productive workforce.

Gauteng Non-profit Organisations Reject Findings of Province’s Forensic Probe

On By ModernMedia

Six out of 13 drug rehabs previously funded by the Gauteng Social Development Department are now “under investigation”

Non-profit organisations whose funding by the Gauteng Department of Social Development has been withdrawn say they are being unfairly punished for “frivolous” and “flimsy” findings made by forensic auditors.

Among the organisations concerned are women’s shelters, drug rehabilitation centres and organisations that provide meals and social work services to homeless people. Many say they have no choice but to scale down their services and even close their doors.

Only seven in-patient drug rehabilitation centres, out of 13 that received funding last year, will be receiving funds for the first two quarters of this financial year, the department confirmed to GroundUp on Wednesday. Six rehabs are under investigation, the department said. 

A manager at a children’s home told GroundUp earlier this week that they had to send a teenager struggling with substance use disorder back to their family because there were no state-funded in-patient drug rehabilitation centres available in the West Rand.

Forensic auditors were appointed by the department in 2023 to probe allegations of maladministration and fraud in the non-profit sector. The department’s budget for non-profit organisations is R1.9-billion for 2024/25, but Gauteng premier Panyaza Lesufi has promised it will be increased to R2.4-billion. Fourteen department officials have been suspended based on findings of forensic audits, the department has said.

The forensic audits were supported by outgoing MEC Mbali Hlophe. Hlophe has claimed several times that non-profit organisations in the province were “stealing from the poor” and that there has been extensive corruption in the sector.

A report provided by the department to the Gauteng Care Crisis Committee last week, on the orders of the Gauteng High Court, contains a list of 53 organisations that are under investigation, out of several hundred funded by the department.

Among the organisations on the list are Daracorp and Beauty Hub which received millions of rands in subsidies for training, while others have had their budgets cut.

But while organisations such as these have received large amounts of funding under questionable circumstances, the department has not provided evidence that this applies to all organisations on the list.

In May, almost two months into the new financial year, organisations flagged in the investigations started receiving letters informing them that they would not receive funding due to the findings made by the auditors. Some only received the letters in June.

When they requested clarity from the department, some received details in writing. But others were only given reasons for the suspension of their funding during a meeting with the department’s lawyers on Wednesday.

GroundUp spoke to representatives of five organisations who attended Wednesday’s meeting. They said the findings they were presented with on Wednesday were minor issues that should have been picked up by the department’s own monitoring and evaluation teams and would have been quickly resolved. They said they did not understand why a forensic audit was necessary.

The organisations have not received any funding from the department since the end of the financial year in March, and are battling to keep going.

“Flimsy and frivolous”

Derick Matthews, CEO of the Freedom Recovery Centre, which until March was funded for 52 beds for in-patient drug rehabilitation, told GroundUp that the allegations against the centre are “flimsy” and “frivolous”.

Matthews was told at Wednesday’s meeting that Freedom Recovery Centre had not submitted audited financial statements for 2022. GroundUp has seen evidence that he submitted the audited financial statements.

Matthews said the department had never before raised concerns about the organisation’s compliance with legislation. He said every quarter the department’s monitoring and evaluation officials would check the centre’s financial statements and that no concerns had ever been raised.

The auditors also found a “high turnover of security personnel” at Freedom Recovery Centre which was causing “instability in the organisation”. Matthews explained that this was because the security staff are employed from the centre’s skills development programme, through which a person who has been sober for a year works for three to six months at the centre.

“They are paid salaries from DSD funding. Our security is not working directly with the residents so they cannot impact the stability of the centre,” Matthews said.

The third finding against Freedom Recovery Centre was that staff members were being given “loans”. Matthews explained that sometimes when the department paid subsidies late, the centre would pay part of staff salaries from the tuck shop’s funds, which would later be deducted from their salaries.

Matthews says that they are in the process of discharging their last state-funded patients. “Both government-funded centres that we have been told to send people to during this crisis are full, they can’t help us. In the last week, I’ve received about 12 phone calls of people that needed urgent help and we can’t even help or intervene,” he said.

Representatives of other organisations GroundUp spoke to had similar concerns about the findings against them but did not want to be named for fear of victimisation.

They also raised concerns that their meeting on Wednesday was with only one department official and the department’s lawyers, while the organisations themselves did not have lawyers present.

They were told they have until Monday to provide evidence to dispute the allegations against them.

At the meeting on Saturday convened by Gauteng Premier Panyaza Lesufi, it was agreed that the organisations would receive an interim service-level agreement from the department by Monday, which would be finalised once the organisations were cleared. But not one organisation GroundUp spoke to has received an interim service-level agreement. Then on Wednesday they were told they will receive the agreements next week.

One organisation under investigation, Child Welfare Tshwane, was finally paid by the department last week after Gauteng High Court Judge Ingrid Opperman issued a directive that the organisation be paid to prevent harm to the beneficiaries.

GroundUp sent detailed questions to the Gauteng Department of Social Development, but we were told that the department will not be responding to media queries relating to the non-profit sector until further notice.

Cutting Down on Salt Levels Stimulates Kidney Regeneration

On By ModernMedia

A loss of salt and body fluid can stimulate kidney regeneration and repair in mice, according to a study published in The Journal of Clinical Investigation. This innate regenerative response relies on a small population of kidney cells in a region known as the macula densa (MD), which senses salt and exerts control over filtration, hormone secretion, and other key functions of this vital organ.

“Our personal and professional mission is to find a cure for kidney disease, a growing global epidemic affecting one out of seven adults, which translates to 850 million people worldwide…” said study leader Janos Peti-Peterdi, a professor of physiology, neuroscience and medicine at the Keck School of Medicine of USC. “Currently, there is no cure for this silent disease. By the time kidney disease is diagnosed, the kidneys are irreversibly damaged and ultimately need replacement therapies, such as dialysis or transplantation.”

To address this growing epidemic, Peti-Peterdi, first author Georgina Gyarmati, and their colleagues took a highly non-traditional approach. As opposed to studying how diseased kidneys fail to regenerate, the scientists focused on how healthy kidneys originally evolved.

“From an evolutionary biology perspective, the primitive kidney structure of the fish turned into more complicated and more efficiently working kidneys to absorb more salt and water,” said Peti-Peterdi. “This was necessary for adaptation to the dry land environment when the animal species moved from the salt-rich seawater. And that’s why birds and mammals have developed MD cells and this beautiful, bigger, and more efficient kidney structure to maintain themselves and functionally adapt to survive. These are the mechanisms that we are targeting and trying to mimic in our research approach.”

With this evolutionary history in mind, the research team fed lab mice a very low salt diet, along with a commonly prescribed drug called an ACE inhibitor that furthered lowered salt and fluid levels. The mice followed this regimen for up to two weeks, since extremely low salt diets can trigger serious health problems if continued long term.

In the region of the MD, the scientists observed regenerative activity, which they could block by administering drugs that interfered with signals sent by the MD. This underscored the MD’s key role in orchestrating regeneration.

When the scientists furthered analysed mouse MD cells, they identified both genetic and structural characteristics that were surprisingly similar to nerve cells. This is an interesting finding, because nerve cells play a key role in regulating the regeneration of other organs such as the skin.

In the mouse MD cells, the scientists also identified specific signals from certain genes, including Wnt, NGFR, and CCN1, which could be enhanced by a low-salt diet to regenerate kidney structure and function. In keeping with these findings in mice, the activity of CCN1 was found to be greatly reduced in patients with chronic kidney disease (CKD).

To test the therapeutic potential of these discoveries, the scientists administered CCN1 to mice with a type of CKD known as focal segmental glomerulosclerosis. They also treated these mice with MD cells grown in low-salt conditions. Both approaches were successful, with the MD cell treatment producing the biggest improvements in kidney structure and function. This might be due to the MD cells secreting not only CCN1, but also additional unknown factors that promote kidney regeneration.

“We feel very strongly about the importance of this new way of thinking about kidney repair and regeneration,” said Peti-Peterdi. “And we are fully convinced that this will hopefully end up soon in a very powerful and new therapeutic approach.”

Which is Better? Prolonged vs Intermittent Infusion of β-Lactams in Sepsis

On By ModernMedia

In adults with sepsis or septic shock, β-lactams are recommended by Surviving Sepsis Campaign guidelines, in a prolonged (after an initial bolus) rather than intermittent infusions – but owing to only moderate quality of evidence this is currently a weak recommendation. Now, a new systematic review and meta-analysis comparing the two approaches across multiple clinical trials has found a survival benefit for prolonged infusion The findings appear in JAMA.

To address whether prolonged infusions of β-lactams improve clinically important outcomes in critically ill adults with sepsis or septic shock, the study investigators searched medical databases for relevant randomised controlled trials comparing β-lactam infusion types in critically ill adults with sepsis or septic shock. The primary outcome was 90-day mortality, with secondary outcomes including intensive care unit (ICU) mortality and clinical cure.

In all, they found 18 eligible trials that included 9108 critically ill adults with sepsis or septic shock (median age, 54 years; 5961 men [65%]), 17 trials (9014 participants) contributed data to the primary outcome.

The pooled estimated risk ratio for all-cause 90-day mortality for prolonged infusions of β-lactam antibiotics compared with intermittent infusions was 0.86, with high certainty and a 99.1% posterior probability that prolonged infusions were associated with lower 90-day mortality. There was high certainty that prolonged infusion of β-lactam antibiotics was associated with a reduced risk of ICU mortality (risk ratio, 0.84) and moderate certainty of an increase in clinical cure (risk ratio, 1.16).

The findings were tempered with the authors’ understanding that, “Potential challenges associated with prolonged infusion administration, including drug instability and incompatibility with other intravenous medications, the need for a dedicated intravenous portal, and the potential effect on clinical workload, require some considerations before broad implementation. Future studies should determine the optimal duration of infusion when β-lactam antibiotics are administered as prolonged infusions.”

The authors concluded that, “Among adults in the intensive care unit who had sepsis or septic shock, the use of prolonged β-lactam antibiotic infusions was associated with a reduced risk of 90-day mortality compared with intermittent infusions. The current evidence presents a high degree of certainty for clinicians to consider prolonged infusions as a standard of care in the management of sepsis and septic shock.”
