Scurvy: A Diagnosis Still Relevant Today
“Petechial rash often prompts further investigation into hematological, dermatological, or vasculitis causes. However, if the above investigations are negative and skin biopsy has not revealed a cause, there is a Renaissance-era diagnosis that is often overlooked but is easily investigated and treated,” wrote Andrew Dermawan, MD, and colleagues from Sir Charles Gairdner Hospital in Nedlands, Australia, in BMJ Case Reports. The diagnosis they highlight is scurvy, a disease that has faded from common medical concern but is reemerging, partly because of the rise in bariatric surgery.
Diagnosing Scurvy in the 2020s
In their article, Dermawan and colleagues present the case of a 50-year-old man with a bilateral petechial rash on his lower limbs, without any history of trauma. The patient, who exhibited no infectious symptoms, also had gross hematuria, microcytic anemia, mild neutropenia, and lymphopenia. Tests for autoimmune and hematological diseases were negative, as were abdominal and leg CT scans, ruling out abdominal hemorrhage and vasculitis. Additionally, a skin biopsy showed no causative findings.
The doctors noted that the patient had undergone sleeve gastrectomy, prompting them to inquire about his diet. They discovered that, because of financial difficulties, his diet primarily consisted of processed foods with little to no fruits or vegetables, and he had stopped taking supplements recommended by his gastroenterologist. Further tests revealed a vitamin D deficiency and a severe deficiency in vitamin C. With the diagnosis of scurvy confirmed, the doctors treated the patient with 1000 mg of ascorbic acid daily, along with cholecalciferol, folic acid, and a multivitamin complex, leading to a complete resolution of his symptoms.
Risk Factors Then and Now
It can cause mucosal and gastric hemorrhages, and if left untreated, it can lead to fatal bleeding.
Historically known as “sailors’ disease,” scurvy plagued men on long voyages who lacked access to fresh fruits or vegetables and thus did not get enough vitamin C. In 1747, James Lind, a British physician in the Royal Navy, demonstrated that the consumption of oranges and lemons could combat scurvy.
Today’s risk factors for scurvy include malnutrition, gastrointestinal disorders (eg, chronic inflammatory bowel diseases), alcohol and tobacco use, eating disorders, psychiatric illnesses, dialysis, and the use of medications that reduce the absorption of ascorbic acid (such as corticosteroids and proton pump inhibitors).
Scurvy remains more common among individuals with unfavorable socioeconomic conditions. The authors of the study emphasize how the rising cost of living — specifically in Australia but applicable elsewhere — is changing eating habits, leading to a high consumption of low-cost, nutritionally poor foods.
Poverty has always been a risk factor for scurvy, but today there may be an additional cause: bariatric surgery. Patients undergoing these procedures are at a risk for deficiencies in fat-soluble vitamins A, D, E, and K, and if their diet is inadequate, they may also experience a vitamin C deficiency. Awareness of this can facilitate the timely diagnosis of scurvy in these patients.

Angiotensin Receptor Blockers May Lead to Worse Outcomes in Celiac Disease
PHILADELPHIA — , according to a study presented at the American College of Gastroenterology (ACG) 2024 Annual Scientific Meeting.
The association may be related to the similar pathophysiology between ARB-associated enteropathy and celiac disease, though additional research is needed.
“Based on our findings, people should take caution when prescribing angiotensin receptor blockers to people with celiac disease,” said lead author Isabel Hujoel, MD, clinical assistant professor of gastroenterology and clinic director of the Celiac Disease Center at the University of Washington, Seattle.
“When we see someone with nonresponsive celiac disease, meaning persistent symptoms despite a gluten-free diet, I do think we should review their medication list, and if they’re on an ARB, we should consider a trial off those medications to see if they respond,” she said. “A primary care provider may choose other hypertensives as well.”
Hujoel and co-author Margaux Hujoel, PhD, a postdoctoral research fellow at Brigham and Women’s Hospital, Boston; Broad Institute, Cambridge; and Harvard Medical School, Boston, analyzed data from the National Institutes of Health’s All of Us, a large publicly available US longitudinal dataset.
The researchers conducted a survival analysis of time-to-first event after celiac disease diagnosis, allowing patients to have a time-dependent covariate of ARB use. They looked at outcomes such as iron deficiency, diarrhea, abdominal pain, vitamin deficiency, vitamin D deficiency, malabsorption, low hemoglobin, and weight loss.
The analysis included 1849 patients with celiac disease, including 1460 women and 389 men, with a median age of nearly 50 years at diagnosis. While the vast majority of patients (nearly 1600) didn’t take an ARB, 120 started one before celiac disease diagnosis and 142 started one after diagnosis.
Overall, taking an ARB was associated with increased hazard ratios [HRs] for low hemoglobin, iron deficiency, diarrhea, and abdominal pain. There weren’t increased risks for weight loss, malabsorption, or vitamin deficiencies.
When excluding those who had an ARB prescription before diagnosis, the HRs remained significantly higher for low hemoglobin (HR, 1.98) and iron deficiency (HR, 1.72) for those who started an ARB after diagnosis.
“The use of angiotensin receptor blockers may be associated with worse outcomes in the setting of celiac disease, specifically persistent symptoms and possibly poor small bowel healing as evidenced by malabsorption,” Hujoel said.
Future studies could look specifically at losartan, which was the most common ARB prescribed in this analysis, she said. Other studies could also analyze different patient outcomes, whether patients were on a gluten-free diet, medication adherence, and recurrence or persistence of symptoms rather than initial occurrence. The associations between ARB use and celiac disease could shift among patients who are in remission, for instance.
“ARBs are some of the most widely used medications, so studies like these can help people to understand that they may have symptoms but not know it’s related to their medication. Public awareness of this fact is key,” said Patricia Jones, MD, a hepatologist and associate professor of clinical medicine at the University of Miami Miller School of Medicine, Miami. Jones co-moderated the plenary session on small intestine, functional, and liver research.
“There are many types of antihypertensives, so while ARBs are used often, other options are available if people have symptoms, especially if they have worsening symptoms with celiac disease,” she said. “It’s important to make changes in your practice.”
The study was named an ACG Newsworthy Abstract. Isabel Hujoel and Patricia Jones reported no relevant disclosures.

Venetoclax-Obinutuzumab: CLL’s New Power Duo?
TOPLINE:
METHODOLOGY:
- A total of 432 patients with previously untreated CLL and coexisting conditions were enrolled in the study.
- Participants were randomized 1:1 to receive either 12 cycles of venetoclax with 6 cycles of obinutuzumab or 12 cycles of chlorambucil with 6 cycles of obinutuzumab.
- The primary endpoint was PFS, with secondary endpoints including TTNT, overall survival (OS), and adverse events.
- Minimal residual disease was assessed in peripheral blood and bone marrow at the end of treatment and at several follow-up points.
- The study was conducted across multiple centers and was registered with clinical trial identifiers NCT02242942 and EudraCT 2014-001810-24.
TAKEAWAY:
- The 6-year PFS rate was significantly higher in the venetoclax-obinutuzumab group (53%) than in the chlorambucil-obinutuzumab group (21.7%) (P < .0001).
- The TTNT rate was 65.2% in the venetoclax-obinutuzumab group vs 37.1% in the chlorambucil-obinutuzumab group (P < .0001).
- The OS rate at 6 years was 78.7% in the venetoclax-obinutuzumab group and 69.2% in the chlorambucil-obinutuzumab group (P = .052).
- Patients in the venetoclax-obinutuzumab group reported better quality of life and less fatigue than those in the chlorambucil-obinutuzumab group.
IN PRACTICE:
“Patients treated with the venetoclax-obinutuzumab combination showed a statistically significant sustained prolongation of PFS, compared with patients treated with chlorambucil-obinutuzumab (76.2 vs 36.4 months). Overall, the PFS rate was 53% in the venetoclax-obinutuzumab group vs 21.7% after chlorambucil-obinutuzumab,” the study’s authors wrote.
In a related article, Silvia Deaglio, University of Turin in Italy, noted: “A second important observation of the study is that in the venetoclax-obinutuzumab arm, patients who relapsed more frequently presented with unmutated IGHV genes, deletion of 17p, or TP53 mutations.”
SOURCE:
This study was led by Othman Al-Sawaf, Sandra Robrecht, and Can Zhang, University of Cologne in Germany. It was published online on October 31 in Blood.
LIMITATIONS:
This study’s limitations included the relatively small sample size and the short duration of follow-up for some endpoints. Additionally, the study population was limited to older adult patients with coexisting conditions, which may limit the generalizability of the findings to a broader CLL population.
DISCLOSURES:
This study was supported by F. Hoffmann-La Roche and AbbVie. Al-Sawaf disclosed receiving grants from BeiGene, AbbVie, Janssen, and Roche. Additional disclosures are noted in the original article.

Plasma Omega-6 and Omega-3 Fatty Acids Inversely Associated With Cancer
TOPLINE:
Higher plasma levels of omega-6 and omega-3 fatty acids are associated with a lower incidence of cancer. However, omega-3 fatty acids are linked to an increased risk for prostate cancer, specifically.
METHODOLOGY:
- Researchers looked for associations of plasma omega-3 and omega-6 polyunsaturated fatty acids (PUFAs) with the incidence of cancer overall and 19 site-specific cancers in the large population-based prospective UK Biobank cohort.
- They included 253,138 participants aged 37-73 years who were followed for an average of 12.9 years, with 29,838 diagnosed with cancer.
- Plasma levels of omega-3 and omega-6 fatty acids were measured using nuclear magnetic resonance and expressed as percentages of total fatty acids.
- Participants with cancer diagnoses at baseline, those who withdrew from the study, and those with missing data on plasma PUFAs were excluded.
- The study adjusted for multiple covariates, including age, sex, ethnicity, socioeconomic status, lifestyle behaviors, and family history of diseases.
TAKEAWAY:
- Higher plasma levels of omega-6 and omega-3 fatty acids were associated with a 2% and 1% reduction in overall cancer risk per SD increase, respectively (P = .001 and P = .03).
- Omega-6 fatty acids were inversely associated with 14 site-specific cancers, whereas omega-3 fatty acids were inversely associated with five site-specific cancers.
- Prostate cancer was positively associated with omega-3 fatty acids, with a 3% increased risk per SD increase (P = .049).
- A higher omega-6/omega-3 ratio was associated with an increased risk for overall cancer, and three site-specific cancers showed positive associations with the ratio. “Each standard deviation increase, corresponding to a 13.13 increase in the omega ratio, was associated with a 2% increase in the risk of rectum cancer,” for example, the authors wrote.
IN PRACTICE:
“Overall, our findings provide support for possible small net protective roles of omega-3 and omega-6 PUFAs in the development of new cancer incidence. Our study also suggests that the usage of circulating blood biomarkers captures different aspects of dietary intake, reduces measurement errors, and thus enhances statistical power. The differential effects of omega-6% and omega-3% in age and sex subgroups warrant future investigation,” wrote the authors of the study.
SOURCE:
The study was led by Yuchen Zhang of the University of Georgia in Athens, Georgia. It was published online in the International Journal of Cancer.
LIMITATIONS:
The study’s potential for selective bias persists due to the participant sample skewing heavily toward European ancestry and White ethnicity. The number of events was small for some specific cancer sites, which may have limited the statistical power. The study focused on total omega-3 and omega-6 PUFAs, with only two individual fatty acids measured. Future studies are needed to examine the roles of other individual PUFAs and specific genetic variants.
DISCLOSURES:
This study was supported by grants from the National Institute of General Medical Sciences of the National Institutes of Health. No relevant conflicts of interest were disclosed by the authors.

- A higher omega-6/omega-3 ratio was associated with an increased risk for overall cancer, and three site-specific cancers showed positive associations with the ratio. “Each standard deviation increase, corresponding to a 13.13 increase in the omega ratio, was associated with a 2% increase in the risk of rectum cancer,” for example, the authors wrote.
IN PRACTICE:
“Overall, our findings provide support for possible small net protective roles of omega-3 and omega-6 PUFAs in the development of new cancer incidence. Our study also suggests that the usage of circulating blood biomarkers captures different aspects of dietary intake, reduces measurement errors, and thus enhances statistical power. The differential effects of omega-6% and omega-3% in age and sex subgroups warrant future investigation,” wrote the authors of the study.
SOURCE:
The study was led by Yuchen Zhang of the University of Georgia in Athens, Georgia. It was published online in the International Journal of Cancer.
LIMITATIONS:
The study’s potential for selective bias persists due to the participant sample skewing heavily toward European ancestry and White ethnicity. The number of events was small for some specific cancer sites, which may have limited the statistical power. The study focused on total omega-3 and omega-6 PUFAs, with only two individual fatty acids measured. Future studies are needed to examine the roles of other individual PUFAs and specific genetic variants.

TOPLINE:
Higher plasma levels of omega-6 and omega-3 fatty acids are associated with a lower incidence of cancer. However, omega-3 fatty acids are linked to an increased risk for prostate cancer, specifically.
METHODOLOGY:
- Researchers looked for associations of plasma omega-3 and omega-6 polyunsaturated fatty acids (PUFAs) with the incidence of cancer overall and 19 site-specific cancers in the large population-based prospective UK Biobank cohort.
- They included 253,138 participants aged 37-73 years who were followed for an average of 12.9 years, with 29,838 diagnosed with cancer.
- Plasma levels of omega-3 and omega-6 fatty acids were measured using nuclear magnetic resonance and expressed as percentages of total fatty acids.
- Participants with cancer diagnoses at baseline, those who withdrew from the study, and those with missing data on plasma PUFAs were excluded.
- The study adjusted for multiple covariates, including age, sex, ethnicity, socioeconomic status, lifestyle behaviors, and family history of diseases.
TAKEAWAY:
- Higher plasma levels of omega-6 and omega-3 fatty acids were associated with a 2% and 1% reduction in overall cancer risk per SD increase, respectively (P = .001 and P = .03).
- Omega-6 fatty acids were inversely associated with 14 site-specific cancers, whereas omega-3 fatty acids were inversely associated with five site-specific cancers.
- Prostate cancer was positively associated with omega-3 fatty acids, with a 3% increased risk per SD increase (P = .049).
- A higher omega-6/omega-3 ratio was associated with an increased risk for overall cancer, and three site-specific cancers showed positive associations with the ratio. “Each standard deviation increase, corresponding to a 13.13 increase in the omega ratio, was associated with a 2% increase in the risk of rectum cancer,” for example, the authors wrote.

Prostate Cancer Treatment Associated With More Complications
TOPLINE:
Radiotherapy increases the risk for bladder cancer and radiation-specific complications, according to the new cohort study.
METHODOLOGY:
- Researchers conducted a cohort study to try to characterize long-term treatment-related adverse effects and complications in patients treated for prostate cancer, compared with a general population of older males.
- They used data from the Prostate Cancer Prevention Trial and the Selenium and Vitamin E Cancer Prevention Trial, linked with Medicare claims. A total of 29,196 participants were included in the study’s control group. Of 3946 patients diagnosed with prostate cancer, 655 were treated with prostatectomy, and 1056 were treated with radiotherapy.
- Participants were followed for a median of 10.2 years, with specific follow-up durations being 10.5 years and 8.5 years for the prostatectomy and radiotherapy groups, respectively.
- The study analyzed ten potential treatment-related complications using Medicare claims data, including urinary incontinence, erectile dysfunction, and secondary cancers.
- Multivariable Cox regression was used to adjust for age, race, and year of time-at-risk initiation, with stratification by study and intervention arm.
TAKEAWAY:
- At 12 years, there was a 7.23 increase in hazard risk for urinary or sexual complications for patients who had prostatectomy, compared with controls (P < .001).
- Radiotherapy-treated patients had a nearly three times greater hazard risk for bladder cancer and a 100-fold increased hazard risk for radiation-specific complications, such as radiation cystitis and radiation proctitis (P < .001).
- The incidence of any treatment-related complication per 1000 person-years was 124.26 for prostatectomy, 62.15 for radiotherapy, and 23.61 for untreated participants.
- The authors stated that these findings highlight the importance of patient counseling before prostate cancer screening and treatment.
IN PRACTICE:
“We found that, after accounting for baseline population rates, most patients with PCA undergoing treatment experience complications associated with worse quality of life and/or new health risks. The magnitude of these risks, compared with the relatively small benefit found by randomized clinical trials of PCA screening and treatment, should be explicitly reflected in national cancer screening and treatment guidelines and be integral to shared decision-making with patients before initiation of PSA screening, biopsy, or PCA treatment,” wrote the authors of the study.
SOURCE:
The study was led by Joseph M. Unger, PhD, SWOG Statistics and Data Management Center, Fred Hutchinson Cancer Center in Seattle, Washington. It was published online on November 7, 2024, in JAMA Oncology.
LIMITATIONS:
The study did not account for multiple comparisons, which may affect the statistical significance of some findings. Claims data are subject to misclassification and may underreport complications that are not reported to a physician. The study did not differentiate among strategies of prostatectomy or radiotherapy, which may result in different patterns of complications. The cohort comprised men enrolled in large, randomized prevention trials, which may limit the generalizability of the incidence estimates. Confounding by unknown factors cannot be ruled out, affecting the attribution of risks to prostate cancer treatment alone.
DISCLOSURES:
Unger disclosed consulting fees from AstraZeneca and Loxo/Lilly outside the submitted work. One coauthor reported grants from the US National Cancer Institute during the conduct of the study. Another coauthor reported employment with Flatiron Health at the time of manuscript submission and review. Additional disclosures are noted in the original article.

Common Crohn’s Immune Response to Gut Bacteria Suggests Therapeutic Target
Many patients with Crohn’s disease (CD) have a heightened immune response to flagellins expressed by commensal gut bacteria Lachnospiraceae, with seroreactivity appearing up to 5 years prior to development of Crohn’s complications, according to investigators.
These findings suggest that lead author Qing Zhao, MD, PhD, of the University of Alabama at Birmingham, and colleagues reported.
Previously, Zhao and colleagues found that about 30% of patients with CD had elevated IgG responses to multiple Lachnospiraceae flagellins, and stronger reactivity was associated with higher flagellin-specific CD4+ T cells in circulation.
“In this study, we aimed to identify immunodominant B cell peptide epitopes shared among Lachnospiraceae bacterial flagellins in patients with CD and to correlate this immune reactivity with the clinical disease course,” the investigators wrote in Gastroenterology.
To this end, the investigators analyzed serum samples from adult CD patients, pediatric CD patients, and healthy infants without inflammatory bowel disease, with data derived from multiple sources. Adult patients with CD were part of a regional cohort recruited at the University of Alabama at Birmingham, while pediatric patients with CD came from the RISK Stratification Study, a multisite cohort study across the United States and Canada. Samples from healthy infants were collected from three diverse geographic locations: Uganda, Sweden, and the United States, providing a broad comparison of immune responses to Lachnospiraceae flagellin across populations.
Samples were analyzed via two main methods: a flagellin peptide microarray and a cytometric bead array. The microarray, comprising sequential Lachnospiraceae-derived peptides, enabled identification of IgG responses specific to individual bacterial peptides. The cytometric bead array allowed for multiplexed detection of IgG, IgA, and IgM antibodies to these peptides, quantifying immune reactivity and enabling correlation with clinical disease data.
This approach revealed that nearly half of patients with CD — both adults and children — had a strong IgG immune response targeting a specific bacterial peptide in the Lachnospiraceae flagellin hinge region. This response was linked to an increased risk of disease complications over time, suggesting the peptide’s potential as a biomarker for CD severity and progression, according to the investigators.
Of note, healthy infants also exhibited an elevated IgG response to the same bacterial peptide at around 1 year of age, but this response declined as they grew older, in contrast to its persistence in CD patients. This difference points to a possible failure in immune tolerance in CD, where the natural immune response to gut bacteria in infancy may become dysregulated, Zhao and colleagues explained.
“The flagellin cytometric bead array used in this study holds potential for a simplified yet robust diagnostic and prognostic assay for Crohn’s disease,” they concluded. “Given that reactivity to the dominant flagellin epitope is strongly associated with the development of disease complications, this technique may also assist in identifying patients with Crohn’s disease who would benefit from early therapy.”
Zhao and colleagues also called for future studies to characterize the role of flagellin hinge peptide–specific IgG antibodies in CD pathogenesis, and to explore the hinge peptide as a potential therapeutic target.The study was supported by a Synergy Award from the Kenneth Rainin Foundation, a Career Development Award from the Crohn’s and Colitis Foundation, and grants from the Department of Veterans Affairs, National Institute of Allergy and Infectious Diseases, National Institutes of Health, and National Institute of Diabetes and Digestive and Kidney Diseases. One coauthor and the University of Alabama at Birmingham hold a patent on Lachnospiraceae A4 Fla2, licensed for clinical application by Prometheus Laboratories. Four study coauthors have filed a patent for the flagellin peptide cytometric bead array. One coauthor serves as the founder and chief scientific officer of ImmPrev Bio, a company developing an antigen-directed immunotherapy for Crohn’s disease.

FROM GASTROENTEROLOGY
Digital Danger: How Cyberattacks Put Patients at Risk
On September 27, 2024, UMC Health System in Lubbock, Texas, experienced an IT outage because of a cybersecurity incident that temporarily diverted patients to other healthcare facilities. So far, in 2024, there have been 386 cyberattacks on healthcare organizations. These high-impact ransomware attacks disrupt and delay patient care.
In recent years, many healthcare systems, including Scripps Health, Universal Health Services, Vastaamo, Sky Lakes, and the University of Vermont, have paid millions — even tens of millions — to recover data after a cyberattack or data breach. When healthcare systems come under cyber fire, the impact extends far past disrupting workflows and compromising data, patient safety can be also be compromised, vital information may be lost, and imaging and lab results can go missing or be held for ransom, making physicians’ job difficult or impossible.
In fact, cyberattacks on hospitals are far more common than you may realize. A new report issued by Ponemon and Proofpoint found that 92% of healthcare organizations have experienced a cyberattack in the past 12 months. Even more sobering is that about half of the organizations affected suffered disruptions in patient care.
Healthcare Systems = ‘Soft Targets’
Healthcare systems are a “soft target” for hackers for several reasons, pointed out Matthew Radolec, vice president, incident response and cloud operations at Varonis, a data security company. “One, they’re usually an amalgamation of many healthcare systems that are interconnected,” said Radolec. “A lot of hospitals are connected to other hospitals or connected to educational institutions, which means their computer vulnerabilities are shared ... and if they have an issue, it could very easily spread to your network.”
Another factor is the cost of securing data. “[With hospitals], they’ll say that a dollar spent on security is a dollar not spent on patient care,” said Radolec. “So the idea of investing in security is really tough from a budget standpoint…they’re choosing between a new MRI machine or better antivirus, backups, or data security.”
Because of the wealth of private data and healthcare information they maintain, hospitals are considered “high impact” for cybercriminals. Attackers know that if they get a foothold in a hospital, it’s more likely to pay — and pay quickly, Radolec told this news organization. Hospitals are also likely to have cyber insurance to help cover the cost of having their data stolen, encrypted, and ransomed.
The 2024 Microsoft Digital Defense Report also found that the bad actors are more sophisticated and better resourced and can challenge even the best cybersecurity. Improved defenses may not be good enough, and the sheer volume of attacks must be met with effective deterrence and government solutions that impose consequences for cybercriminals.
Vulnerable Users
Whether through a phishing email or text, password attack, or web attack, “the moment a ‘threat actor’ gets into your institution and gets credentials ... that’s the Nirvana state of a threat actor,” warned Ryan Witt, chair of the healthcare customer advisory board and vice president of Industry Solutions at Proofpoint, a cybersecurity platform. “They have those credentials and will go into deep reconnaissance mode. It often takes healthcare up to 6 months to even ascertain whether somebody’s actually in the network.” During that time, the hacker is learning how the institution works, what job functions matter, and how best to plan their attack.
“Attackers are getting in because they’re buying databases of usernames and passwords. And they’re trying them by the millions,” added Radolec. “For a sophisticated actor, all it takes is time and motivation. They have the skills. It’s just a matter of how persistent they want to be.”
Certain hospital staff are also more likely to be targeted by cyberhackers than others. “About 10% of a healthcare organization’s user base is much more vulnerable for all sorts of reasons — how they work, the value of their job title and job function, and therefore their access to systems,” said Witt.
High-profile staff are more likely to be targeted than those in lower-level positions; the so-called “CEO attack” is typical. However, staff in other hospital departments are also subject to cybercriminals, including hospice departments/hospice organizations and research arms of hospitals.
The Impact of Cyberattacks on Patients
Physicians and healthcare execs may have considered cybersecurity more of a compliance issue than a true threat to patients in the past. But this attitude is rapidly changing. “We are starting to see a very clear connection between a cyber event and how it can impact patient care and patient safety,” said Witt.
According to the Proofpoint report, cyber breaches can severely affect patient care. In 2024:
- 56% of respondents saw a delay in patient tests/procedures
- 53% experienced increased patient complications from medical procedures
- 52% noted a longer patient length of stay
- 44% saw an increase in patient transfers to other facilities
- 28% had an increase in mortality rate
What Hospitals and Physicians Can Do
Fortunately, hospitals can take measures to better protect their data and their patients. One strategy is segmenting networks to reduce the amount of data or systems one person or system can access. Educating staff about the dangers of phishing and spoofing emails also help protect organizations from ransomware attacks. Having staff avoid reusing passwords and updating logins and passwords frequently helps.
Most hospitals also need more robust security controls. Physicians and healthcare facilities must also embrace the cybersecurity controls found in other industries, said Witt. “Multifactor authentication is one of those things that can cause us frustration,” he said. “The controls can seem onerous, but they’re really valuable overall…and should become standard practice.”
Doctors can also prepare for a ransomware attack and protect patients by practicing some “old-school” medicine, like using paper systems and maintaining good patient notes — often, those notes are synced locally as well as offsite, so you’d be able to access them even during a data breach. “It’s smart to write prescriptions on pads sometimes,” said Radolec. “Don’t forget how to do those things because that will make you more resilient in the event of a ransomware attack.”
A Continuing Threat
Cyberattacks will continue. “When you look at the high likelihood [of success] and the soft target, you end up with ... a perfect storm,” said Radolec. “Hospitals have a lot of vulnerabilities. They have to keep operations going just to receive income, but also to deliver care to people.”
That means that the burden is on healthcare organizations — including physicians, nurses, staff, and C-level execs — to help keep the “security” in cybersecurity. “We are all part of the cybersecurity defense,” said Witt. Helping to maintain that defense has become a critical aspect of caring for patients.

Attackers know that if they get a foothold in a hospital, it’s more likely to pay — and pay quickly, Radolec told this news organization. Hospitals are also likely to have cyber insurance to help cover the cost of having their data stolen, encrypted, and ransomed.
The 2024 Microsoft Digital Defense Report also found that the bad actors are more sophisticated and better resourced and can challenge even the best cybersecurity. Improved defenses may not be good enough, and the sheer volume of attacks must be met with effective deterrence and government solutions that impose consequences for cybercriminals.
Vulnerable Users
Whether through a phishing email or text, password attack, or web attack, “the moment a ‘threat actor’ gets into your institution and gets credentials ... that’s the Nirvana state of a threat actor,” warned Ryan Witt, chair of the healthcare customer advisory board and vice president of Industry Solutions at Proofpoint, a cybersecurity platform. “They have those credentials and will go into deep reconnaissance mode. It often takes healthcare up to 6 months to even ascertain whether somebody’s actually in the network.” During that time, the hacker is learning how the institution works, what job functions matter, and how best to plan their attack.
“Attackers are getting in because they’re buying databases of usernames and passwords. And they’re trying them by the millions,” added Radolec. “For a sophisticated actor, all it takes is time and motivation. They have the skills. It’s just a matter of how persistent they want to be.”
Certain hospital staff are also more likely to be targeted by cyberhackers than others. “About 10% of a healthcare organization’s user base is much more vulnerable for all sorts of reasons — how they work, the value of their job title and job function, and therefore their access to systems,” said Witt.
High-profile staff are more likely to be targeted than those in lower-level positions; the so-called “CEO attack” is typical. However, staff in other hospital departments are also subject to cybercriminals, including hospice departments/hospice organizations and research arms of hospitals.
The Impact of Cyberattacks on Patients
Physicians and healthcare execs may have considered cybersecurity more of a compliance issue than a true threat to patients in the past. But this attitude is rapidly changing. “We are starting to see a very clear connection between a cyber event and how it can impact patient care and patient safety,” said Witt.
According to the Proofpoint report, cyber breaches can severely affect patient care. In 2024:
- 56% of respondents saw a delay in patient tests/procedures
- 53% experienced increased patient complications from medical procedures
- 52% noted a longer patient length of stay
- 44% saw an increase in patient transfers to other facilities
- 28% had an increase in mortality rate
What Hospitals and Physicians Can Do
Fortunately, hospitals can take measures to better protect their data and their patients. One strategy is segmenting networks to reduce the amount of data or systems one person or system can access. Educating staff about the dangers of phishing and spoofing emails also help protect organizations from ransomware attacks. Having staff avoid reusing passwords and updating logins and passwords frequently helps.
Most hospitals also need more robust security controls. Physicians and healthcare facilities must also embrace the cybersecurity controls found in other industries, said Witt. “Multifactor authentication is one of those things that can cause us frustration,” he said. “The controls can seem onerous, but they’re really valuable overall…and should become standard practice.”
Doctors can also prepare for a ransomware attack and protect patients by practicing some “old-school” medicine, like using paper systems and maintaining good patient notes — often, those notes are synced locally as well as offsite, so you’d be able to access them even during a data breach. “It’s smart to write prescriptions on pads sometimes,” said Radolec. “Don’t forget how to do those things because that will make you more resilient in the event of a ransomware attack.”
A Continuing Threat
Cyberattacks will continue. “When you look at the high likelihood [of success] and the soft target, you end up with ... a perfect storm,” said Radolec. “Hospitals have a lot of vulnerabilities. They have to keep operations going just to receive income, but also to deliver care to people.”
That means that the burden is on healthcare organizations — including physicians, nurses, staff, and C-level execs — to help keep the “security” in cybersecurity. “We are all part of the cybersecurity defense,” said Witt. Helping to maintain that defense has become a critical aspect of caring for patients.

On September 27, 2024, UMC Health System in Lubbock, Texas, experienced an IT outage because of a cybersecurity incident that temporarily diverted patients to other healthcare facilities. So far, in 2024, there have been 386 cyberattacks on healthcare organizations. These high-impact ransomware attacks disrupt and delay patient care.
In recent years, many healthcare systems, including Scripps Health, Universal Health Services, Vastaamo, Sky Lakes, and the University of Vermont, have paid millions — even tens of millions — to recover data after a cyberattack or data breach. When healthcare systems come under cyber fire, the impact extends far past disrupting workflows and compromising data, patient safety can be also be compromised, vital information may be lost, and imaging and lab results can go missing or be held for ransom, making physicians’ job difficult or impossible.
In fact, cyberattacks on hospitals are far more common than you may realize. A new report issued by Ponemon and Proofpoint found that 92% of healthcare organizations have experienced a cyberattack in the past 12 months. Even more sobering is that about half of the organizations affected suffered disruptions in patient care.
Healthcare Systems = ‘Soft Targets’
Healthcare systems are a “soft target” for hackers for several reasons, pointed out Matthew Radolec, vice president, incident response and cloud operations at Varonis, a data security company. “One, they’re usually an amalgamation of many healthcare systems that are interconnected,” said Radolec. “A lot of hospitals are connected to other hospitals or connected to educational institutions, which means their computer vulnerabilities are shared ... and if they have an issue, it could very easily spread to your network.”
Another factor is the cost of securing data. “[With hospitals], they’ll say that a dollar spent on security is a dollar not spent on patient care,” said Radolec. “So the idea of investing in security is really tough from a budget standpoint…they’re choosing between a new MRI machine or better antivirus, backups, or data security.”

Liquid Fasting Mitigates Negative Pre-Surgery Impact of Semaglutide
These findings suggest that patients taking GLP-1 receptor agonists (GLP-1RAs) may benefit from a 24-hour liquid fast before anesthetic procedures without the need for a medication hold, reported lead author Haarika Korlipara, MD, of NewYork–Presbyterian/Weill Cornell Medical Center, New York, and colleagues.
“[T]he effects of delayed gastric emptying in patients on long-acting GLP-1RAs are clinically important in the management of anesthetized patients, who may develop periprocedural complications in the setting of retained solid gastric contents,” the investigators wrote in Techniques and Innovations in Gastrointestinal Endoscopy.
The researchers retrospectively analyzed clinical data from 1,212 patients undergoing upper endoscopy at a tertiary care center. Among them, 602 were on semaglutide for more than four weeks, while 610 were controls not taking the medication.
The primary outcome was the presence of retained solid gastric contents. Secondary outcomes included the need for intubation, early procedure termination, and recommendations for repeat endoscopy.
Semaglutide use was an independent predictor of retained solid gastric contents (odds ratio [OR], 4.74; 95% CI, 2.40-9.35; P less than .0001). Multivariable propensity-matched analysis showed a 6% absolute increase in retained gastric contents in the semaglutide group compared to controls (P less than .0001).
This increase appeared clinically relevant, as semaglutide use was associated with a higher rate of early procedure termination (OR, 3.09; P = 0.02) and recommendations for repeat endoscopies (OR, 3.61; P = 0.02), “indicating the degree of retained solid gastric contents was enough to limit the intended gastric mucosal examination,” the investigators wrote.
However, patients who underwent same-day colonoscopy, which included a 24-hour clear liquid fast leading up to the procedure, were less likely to have retained gastric contents (OR, 0.41; 95% CI, 0.23-0.73; P = 0.003), suggesting that extended fasting protocols may mitigate the risk of procedural complications.
“Patients with a history of gastroparesis are often advised to stop ingesting solid foods and maintain a clear liquid diet for a longer period than standard ASA guidance before anesthetized procedures,” Dr. Korlipara and colleagues wrote. “In our opinion, this recommendation should be considered in patients on long-term GLP-1RA therapy, in response to the findings reported in this study and others about the protective effects of a 24-hour liquid fast.”
Point-of-care gastric ultrasound may also be considered to evaluate patients at higher risk of retained stomach contents, they added, especially in patients with additional risk factors for delayed gastric emptying.
“Previously published data have linked prolonged gastric emptying delays in patients chronically using these medications,” they wrote. “Considering the effect on blood sugar and associated procedural risk, especially in patients taking this medication for diabetes management, more studies are warranted to determine the effect of medication on periprocedural complications and recommend repeat evaluation.”
After this study was released, new clinical guidance on the use of GLP-1RAs before surgery was co-published by AGA and four other societies. The guidance notes that, in most cases, patients can continue to take GLP-1RAs, but individual risk factors for complications should be assessed prior to surgery. The guidance cautions that patients at high risk for significant GI side effects should follow a liquid diet for 24 hours before a procedure and the anesthesia plan be adjusted accordingly. In rare cases, the procedure should be delayed.
Dr. Korlipara disclosed no conflicts of interest.

FROM TECHNIQUES AND INNOVATIONS IN GASTROINTESTINAL ENDOSCOPY
Plastic Pollution’s Next Victim: The Human Urinary Tract
Although a 2019 World Health Organization (WHO) report concluded that microplastics in drinking water posed no risk to human health, accumulating evidence is beginning to challenge these findings.
Since plastics became widely used in the mid-20th century, they have evolved from a novel substance to an essential component in countless applications, with global production reaching 368 million tons in 2019 and expected to double by 2039. The production and degradation of plastics involve physical, chemical, and biological processes, leading to the formation of tiny fragments known as microplastics (MPs) and nanoplastics (NPs), which accumulate in the environment. Beyond the well-documented environmental harms of MPs and NPs, growing evidence of their presence within the human body raises concerns about their potential to trigger various harmful biological processes. Their detection in the urinary tract and their potential links to kidney and bladder diseases, as shown in animal studies, are particularly alarming.
Impacts Becoming Apparent
As the impact of plastic pollution becomes increasingly apparent, the need for standardized international definitions of MPs and NPs is pressing. Government publications reveal notable discrepancies between organizations in defining these fragmented plastics. The lack of consensus among regulatory bodies highlights the challenges in mitigating the environmental and health impacts of MPs and NPs. The International Organization for Standardization offers the most precise classification, defining MPs as solid, insoluble plastic particles ranging from 1 µm to 1 mm and NPs as particles smaller than 1 µm.
The intrusion of MPs and NPs into the human body, whether through inhalation, ingestion, or skin exposure (via wounds, hair follicles, or sweat glands), has been linked to harmful biological effects, including inflammation, alterations in cellular metabolism, physical cellular damage, and reduced cell viability.
Urinary Tract Plastics
The detection of MPs and NPs in the human urinary tract, combined with limited understanding of their effects, is a growing concern. An exploratory study published earlier this year aimed to systematically summarize the existing literature regarding the presence of MPs and NPs in the urinary tract and their potential consequences, guided by these research questions:
- What are the characteristics of the plastics detected in the human urinary tract?
- How are MPs and NPs defined in the current literature?
- What methodologies are used to explore the presence and effects of MPs and NPs?
- What are the pathophysiologic consequences of the presence of MPs and NPs in the human urinary tract?
For this study, the “urinary tract” included the kidneys, bladder, ureter, urethra, and urine. By focusing on the urinary tract, the study aimed to consolidate current understanding of MPs and NPs, raise awareness of this emerging issue, and lay the groundwork for further research that could contribute to public health policies and clinical practice guidelines.
The researchers conducted a scoping literature review following the recommendations of the JBI [formerly known as the Joanna Briggs Institute). They systematically searched five databases — PubMed, Scopus, CINAHL, Web of Science, and Embase — as well as gray literature sources.
Concerning Study Results
Eighteen articles were identified. The authors represent seven countries: Pakistan (n = 1), the Netherlands (n = 1), the US (n = 1), Taiwan (n = 1), Germany (n = 3), China (n = 5), and Italy (n = 6). Among these studies, six investigated and characterized the presence of MPs and NPs in the human urinary tract. MPs and NPs were detected in urine samples (n = 5), kidney cancer samples (n = 2), and bladder cancer samples (n = 1).
Additionally, 12 studies examined the effects of MPs and NPs on human urinary tract cell lines. Their findings suggest that MPs and NPs have cytotoxic effects, increase inflammation, reduce cell viability, and alter mitogen-activated protein kinase signaling pathways.
Raman spectroscopy was the primary method used to detect and characterize MPs and NPs in human samples (five out of six studies; 83%). Alternatively, pyrolysis-gas chromatography-mass spectrometry combined with direct laser infrared spectroscopy was used in one study.
Further Research Needed
This exploratory study underscores the urgent need for further research and policy development to address the challenges posed by microplastic contamination. It highlights the rapidly emerging threat of human urinary tract contamination by microplastics, questioning the WHO’s claim that microplastics pose no public health risk. The documented cytotoxic effects of microplastics, and their ability to induce inflammation, reduce cell viability, and disrupt signaling pathways, raise significant public health concerns related to bladder cancer, chronic kidney disease, chronic urinary infections, and incontinence.

It highlights the rapidly emerging threat of human urinary tract contamination by microplastics, questioning the WHO’s claim that microplastics pose no public health risk. The documented cytotoxic effects of microplastics, and their ability to induce inflammation, reduce cell viability, and disrupt signaling pathways, raise significant public health concerns related to bladder cancer, chronic kidney disease, chronic urinary infections, and incontinence.

Postpartum Depression Common After Cesarean Delivery
TOPLINE:
About one in six women experience symptoms of postpartum depression (PPD) 2 months after cesarean delivery, with certain obstetric factors such as emergency cesarean delivery before labor, cesarean delivery after labor induction, lack of social support in the operating room, and severe postoperative pain influencing the risk.
METHODOLOGY:
- Researchers conducted a prospective ancillary cohort study of the Tranexamic Acid for Preventing Postpartum Hemorrhage after Cesarean Delivery (TRAAP2) trial to examine the prevalence of PPD 2 months after cesarean delivery and associated risk factors.
- A total of 2793 women (median age, 33.5 years) were included who had a cesarean delivery at 34 or more weeks of gestation; they completed the Edinburgh Postnatal Depression Scale (EPDS), a self-administered questionnaire, at 2 months after delivery.
- Information about the cesarean delivery, postpartum blood loss, immediate postpartum period, psychiatric history, and memories of delivery and postoperative pain were prospectively collected.
- Medical records were used to obtain details about characteristics of patients; 5.0% had a psychiatric history (2.4% composed of depression).
- The main endpoint was a positive screening for symptoms consistent with this depression — defined as a PPD diagnosis — 2 months after caesarian delivery, with an EPDS score of 13 or higher.
TAKEAWAY:
- The prevalence of a provisional PPD diagnosis at 2 months after cesarean delivery was 16.4% (95% CI, 14.9-18.0) with an EPDS score of 13 or higher and was 23.1% (95% CI, 21.4-24.9%) with a cutoff value of 11 or higher.
- Women who had an emergency cesarean delivery before labor had a higher risk for PPD than those who had a normal cesarean delivery before labor started (adjusted odds ratio [aOR], 1.70; 95% CI, 1.15-2.50); women who had started labor after induction but then had a cesarean delivery also had a higher risk for PPD than those who had a cesarean delivery before going into labor (aOR, 1.36; 95% CI, 1.03-1.84).
- Severe pain during the postpartum stay (aOR, 1.73; 95% CI, 1.32-2.26) and bad memories of delivery (aOR, 1.67; 95% CI, 1.14-2.45) were also risk factors for PPD.
- However, women who had social support in the operating room showed a 27% lower risk for PPD (P = .02).
IN PRACTICE:
“Identifying subgroups of women at risk for PPD based on aspects of their obstetric experience could help to screen for women who might benefit from early screening and interventions,” the authors wrote.
SOURCE:
This study was led by Alizée Froeliger, MD, MPH, of the Department of Obstetrics and Gynecology at Bordeaux University Hospital in France, and was published online in American Journal of Obstetrics & Gynecology.
LIMITATIONS:
The study population was derived from a randomized controlled trial, which may have underestimated the prevalence of PPD. The use of a self-administered questionnaire for PPD screening may not have provided a definitive diagnosis. Moreover, this study did not assess the prevalence of depressive symptoms during pregnancy.
DISCLOSURES:
The TRAAP2 trial was supported by a grant from the French Ministry of Health under its Clinical Research Hospital Program. One author reported carrying out consultancy work and lecturing for Ferring Laboratories, GlaxoSmithKline, and other pharmaceutical companies.
