Psoriatic Arthritis Patients Face Higher Burden of Metabolic Syndrome, Meta-Analysis Shows

Sweden: A new meta-analysis published in Clinical Rheumatology highlights that individuals with psoriatic arthritis (PsA) face a significantly greater burden of metabolic syndrome (MetS) compared with the general population and patients with other inflammatory arthropathies such as rheumatoid arthritis (RA) and ankylosing spondylitis (AS).

The study, conducted by Sara Andreasson and Anna Södergren from the Department of Public Health and Clinical Medicine, Umeå University, Sweden, highlights the need for proactive screening and preventive strategies in PsA care.
The researchers systematically reviewed evidence from major databases, including Ovid Medline, Web of Science, and Scopus, up to February 2024. Out of 1,526 screened publications, 20 relevant studies were included in the final analysis. A random-effects model was used to assess prevalence, and funnel plots were used to evaluate potential bias.
The study revealed the following findings:
  • PsA patients had higher odds of developing metabolic syndrome compared to the general population (LogOR 0.93).
  • The risk of metabolic syndrome was greater in PsA patients than in those with rheumatoid arthritis (LogOR 0.63).
  • PsA patients also had a higher prevalence of metabolic syndrome than ankylosing spondylitis patients (LogOR 1.04).
  • The prevalence of metabolic syndrome in PsA was similar to that seen in cutaneous psoriasis (LogOR 0.15).
  • PsA patients showed increased risks of central obesity, hypertriglyceridemia, impaired glucose tolerance, and diabetes mellitus compared with rheumatoid arthritis patients.
The study emphasizes that MetS—a cluster of conditions including abdominal obesity, dyslipidemia, hypertension, and glucose intolerance—significantly contributes to cardiovascular morbidity. The overlap between psoriatic disease pathways, obesity, and endothelial dysfunction may partly explain why PsA patients are particularly vulnerable.
While the findings strongly support intensified monitoring of metabolic health in PsA patients, the authors acknowledged several limitations. Few studies matched participants for age and sex, sample sizes varied widely, and outcome measures were inconsistent. High heterogeneity was observed in some analyses, and a potential publication bias was suggested, particularly in comparisons between PsA and PsO. Moreover, limited data prevented detailed evaluation of MetS components in PsA versus PsO, AS, and general population groups.
Despite these challenges, the meta-analysis reinforces the importance of incorporating cardiovascular risk assessment into routine PsA management. According to the authors, understanding how disease activity, systemic inflammation, and antirheumatic treatments influence MetS development remains an area requiring further research.
“PsA was consistently associated with a higher prevalence of metabolic syndrome compared to the general population, RA, and AS. This highlights the need for systematic screening and early intervention to reduce long-term cardiovascular risks in these patients,” the study noted.
“The results add to growing evidence that comprehensive PsA care should extend beyond joint and skin manifestations to address broader metabolic and cardiovascular health. Proactive measures, including lifestyle modification, treatment of metabolic risk factors, and achieving minimal disease activity, could play a key role in reducing complications for this vulnerable patient population,” the authors concluded.

Excessive screen time among youth may pose heart health risks: Study

Children and young adults who spend excessive hours glued to screens and electronic devices may have higher risks for cardiometabolic diseases, such as high blood pressure, high cholesterol and insulin resistance, according to new research published today in the Journal of the American Heart Association, an open-access, peer-reviewed journal of the American Heart Association.

A 2023 scientific statement from the American Heart Association noted that “cardiometabolic risk is accruing at younger and younger ages,” and only 29% of American youth, ages 2 to 19 years, had favorable cardiometabolic health based on 2013-2018 data from the National Health and Nutrition Examination Survey.

This analysis of more than 1,000 participants in two studies in Denmark found that increased recreational screen time was significantly associated with higher cardiovascular risks and cardiometabolic risks among children and adolescents.

“Limiting discretionary screen time in childhood and adolescence may protect long-term heart and metabolic health,” said study lead author David Horner, M.D., PhD., a researcher at the Copenhagen Prospective Studies on Asthma in Childhood (COPSAC) at the University of Copenhagen in Denmark. “Our study provides evidence that this connection starts early and highlights the importance of having balanced daily routines.”

Using data from a group of 10-year-olds studied in 2010 and a group of 18-year-olds in 2000 that were part of the Copenhagen Prospective Studies on Asthma in Childhood cohorts, researchers examined the relationship between screen time and cardiometabolic risk factors. Screen time included time spent watching TV, movies, gaming or using phones, tablets or computers for leisure.

Researchers developed a composite score based on a cluster of metabolic syndrome components — waist size, blood pressure, high-density lipoprotein or HDL “good” cholesterol, triglycerides and blood sugar levels – and adjusted for sex and age. The cardiometabolic score reflected a participant’s overall risk relative to the study group average (measured in standard deviations): 0 means average risk, and 1 means one standard deviation above average.

The analysis found that each extra hour of screen time increased the cardiometabolic score by about 0.08 standard deviations in the 10-year-olds and 0.13 standard deviations in the 18-year-olds. “This means a child with three extra hours of screen time a day would have roughly a quarter to half a standard-deviation higher risk than their peers,” Horner said.

“It’s a small change per hour, but when screen time accumulates to three, five or even six hours a day, as we saw in many adolescents, that adds up,” he said. “Multiply that across a whole population of children, and you’re looking at a meaningful shift in early cardiometabolic risk that could carry into adulthood.”

The analysis also found that both sleep duration and sleep timing affected the relationship between screen time and cardiometabolic risk. Both shorter sleep duration and going to sleep later intensified the relationship between screen time and cardiometabolic risk. Children and adolescents who had less sleep showed significantly higher risk associated with the same amount of screen time.

“In childhood, sleep duration not only moderated this relationship but also partially explained it: about 12% of the association between screen time and cardiometabolic risk was mediated through shorter sleep duration,” Horner said. “These findings suggest that insufficient sleep may not only magnify the impact of screen time but could be a key pathway linking screen habits to early metabolic changes.”

In addition, a machine learning analysis identified a unique metabolic signature in the blood that appeared to be associated with screen time.

“We were able to detect a set of blood-metabolite changes, a ‘screen-time fingerprint,’ validating the potential biological impact of the screen time behavior,” he said. “Using the same metabolomics data, we also assessed whether screen time was linked to predicted cardiovascular risk in adulthood, finding a positive trend in childhood and a significant association in adolescence. This suggests that screen-related metabolic changes may carry early signals of long-term heart health risk.

“Recognizing and discussing screen habits during pediatric appointments could become part of broader lifestyle counseling, much like diet or physical activity,” he said. “These results also open the door to using metabolomic signatures as early objective markers of lifestyle risk.”

Amanda Marma Perak, M.D., M.S.CI., FAHA, chair of the American Heart Association’s Young Hearts Cardiovascular Disease Prevention Committee, who was not involved in this research, said focusing on sleep is a great starting point to change screen time patterns.

“If cutting back on screen time feels difficult, start by moving screentime earlier and focusing on getting into bed earlier and for longer,” said Perak, an assistant professor of pediatrics and preventive medicine at Northwestern University Feinberg School of Medicine in Chicago.

Adults can also set an example, she said. “All of us use screens, so it’s important to guide kids, teens and young adults to healthy screen use in a way that grows with them. As a parent, you can model healthy screen use – when to put it away, how to use it, how to avoid multitasking. And as kids get a little older, be more explicit, narrating why you put away your devices during dinner or other times together.

“Make sure they know how to entertain and soothe themselves without a screen and can handle being bored! Boredom breeds brilliance and creativity, so don’t be bothered when your kids complain they’re bored. Loneliness and discomfort will happen throughout life, so those are opportunities to support and mentor your kids in healthy ways to respond that don’t involve scrolling.”

As an observational study using prospectively collected data, the findings reflect associations rather than proving cause and effect. Moreover, parents of the 10-year-olds and the 18-year-olds reported screen time through questionnaires, which may not accurately reflect the actual time youth spent on screens.

Horner suggested that future research could explore whether limiting screen use in the hours before sleep, when light from screen exposure may disrupt circadian rhythms and disrupt sleep onset, may be an avenue to help reduce cardiometabolic risk.

Study details, background and design:

  • The two prospective research groups at COPSAC in Denmark consisted of mother-child pairs, with analysis of data collected at planned clinical visits and study assessments from the birth of the children through age 10 in the 2010 study group and age 18 in the 2000 study group.
  • Through questionnaires, parents of children in the 10-year-old group and 18-year-olds detailed the number of hours the young participants spent watching TV or movies, gaming on a console/TV and using phones, tablets or computers for leisure.
  • For the 2010 group, the number of hours of screen time was available for 657 children at age 6 and 630 children at age 10. Average screen time was two hours per day at age 6, and 3.2 hours per day at age 10, representing a significant increase over time.
  • For the 2000 group of 18-year-olds, screen time was available for 364 individuals. Screen time at 18 years was significantly higher at an average of 6.1 hours per day.
  • Sleep was measured by sensors over a 14-day period.

Exposure to air pollution worsens Alzheimer’s disease, Penn research finds

Exposure to high concentrations of air pollution may worsen Alzheimer’s disease (AD) by accelerating the buildup of toxic proteins in the brain and speeding up cognitive decline. For the first time, post-mortem tissue from people with AD revealed that those who lived in areas with higher concentrations of fine particulate matter in the air even just one year had more severe accumulation of amyloid plaques and tau tangles-hallmarks of Alzheimer’s pathology-compared to those with less exposure. These individuals also experienced faster cognitive and functional decline, including memory loss, impaired judgment, and difficulty with personal care, according to research published today in JAMA Neurology from the Perelman School of Medicine at the University of Pennsylvania.

“This study shows that air pollution doesn’t just increase the risk of dementia-it actually makes Alzheimer’s disease worse,” said Edward Lee, MD, PhD, co-director of Penn’s Institute on Aging. “As researchers continue to search for new treatments, it’s important to uncover all of the factors that contribute to the disease, including the influence of the environment in which they live.”

Health risks from tiny air particles

Air pollution is made up of fine particulate matter, or the tiny, inhalable particles, ranging from 10 micrometers to less than 2.5 micrometers wide, about half the width of a single strand of spider web. It can come from wildfire smoke, car exhaust, construction site debris, or combustion from factories. Particulate matter 2.5 micrometers and smaller (PM2.5) is so small that when inhaled, the particles can be absorbed into the blood stream and cause health concerns. Previous research has linked air pollution containing PM2.5 with dementia, loss of cognitive function, and accelerated cognitive decline.

The researchers examined brain samples from over 600 autopsies from the Penn Medicine Brain Bank. Using data from satellites and local air quality monitors, the researchers modeled the amount of PM2.5 in the air based on where each person lived. They found that for every increase of 1 microgram per cubic meter of PM2.5, the risk for worse Alzheimer’s disease amyloid and tau buildup increased by 19 percent.

Further, when they examined the clinical records of these individuals, researchers found that those who lived in areas with high concentrations of PM2.5 with advanced pathology also had greater cognitive impairment and more rapid onset of symptoms, including memory loss, difficulty with speech, and diminished judgement, compared to people who lived in areas with lower concentrations of air pollution.

While this study focused on exposures to PM2.5 based on geographic location, researchers acknowledge that they could not account for individual-specific exposures to air pollution, such as exposure to second-hand smoke in the home, or working with potentially dangerous chemicals.

“In the United States, air pollution is at the lowest levels in decades, but even just a year living in an area with high levels of pollution can have a big impact on a person’s risk for developing Alzheimer’s disease,” said Lee. “It underscores the value of environmental justice efforts that focus on reducing air pollution to improve public health.”

FDA Clears Apollo TMS Therapy Devices for Adolescent Depression

Apollo transcranial magnetic stimulation (TMS) therapy devices by neurocare group have received FDA clearance for treating adolescents with major depressive disorder (MDD).

Major depression affects an estimated 5 million adolescents in the U.S. each year, yet treatment options remain limited. Currently, only two oral antidepressants are FDA-approved for use in this age group, and both carry a “black box” warning-the strongest warning the FDA issues for medications-due to an increased risk of suicidal thoughts and actions. These medications have an effectiveness rate of only about 35% in achieving remission, and many patients discontinue due to side effects or lack of clinical benefit.

TMS offers a safe, non-invasive, and drug-free alternative, with no black box warning and no medication-related side effects. Clinical studies show that approximately 60% of patients achieve remission with TMS, making it a promising new treatment option for adolescents who have not found success with other treatments.

During TMS Therapy, clinicians position a magnetic coil on the patient’s head to deliver targeted stimulation to specific brain regions involved in mood regulation. neurocare’s engineering team in Germany has developed advanced technology where the magnetic field is more efficient at providing the prescribed stimulation. This advancement improves the impact of treatment, giving patients the best possible chance to benefit from their psychiatrist’s prescribed therapy.

“Our mission has always been to expand access to safe and effective treatments for those who need them most,” said Stanford Miller, Managing Director of neurocare group’s North American operations. “This clearance allows providers to offer adolescents a proven therapy without the risks and limitations of medication, giving hope to families searching for better treatment options.”

Since 2021, neurocare has installed more than 300 Apollo systems in clinics and major institutions across the U.S., helping with the treatment of complex cases of Major Depressive Disorder (MDD) in adults, as well as Obsessive Compulsive Disorder (OCD). The Apollo TMS Therapy product line is FDA-cleared for the treatment of MDD in adult patients who have not had an adequate response to oral antidepressants. It is also FDA-cleared as an adjunctive treatment for OCD in adult patients who have not responded to traditional therapies. The same advanced technology is now FDA-cleared as an adjunctive treatment for adolescents with MDD. Most private and public insurers cover TMS Therapy for adults with MDD, and an increasing number are extending coverage to adolescents.

Poor Glycaemic Control Around Conception Linked to Higher Preeclampsia Risk in Women With Type 1 Diabetes: Study

Sweden: Women living with type 1 diabetes (T1DM) face a significantly greater risk of preeclampsia during pregnancy, and this risk rises in a dose-dependent manner with worsening blood sugar control around conception, according to new research published in BJOG: An International Journal of Obstetrics & Gynaecology. 

The study, led by Natalie Holowko and colleagues from the Clinical Epidemiology Division, Department of Medicine, Solna, Karolinska Institutet, Stockholm, is the largest of its kind to date. It assessed how peri-conceptional glycaemic control influences the risk of preeclampsia among women with type 1 diabetes mellitus (T1DM), using national registry data from Sweden.
The population-based cohort included over 1.68 million singleton pregnancies between 2003 and 2019, of which 4,429 were in women with T1DM and more than 1.68 million in women without diabetes. Researchers linked the Swedish National Diabetes Register with other health registers to track outcomes, categorising glycaemic control according to HbA1c levels recorded within 90 days before or after conception. HbA1c was grouped as <48, 48–61, 62–75, and ≥76 mmol/mol.
The following were the key findings of the study:
  • 16.8% of women with type 1 diabetes developed preeclampsia compared with 2.9% of women without diabetes (aRR 4.7).
  • Risk of preeclampsia increased with higher peri-conceptional HbA1c levels: 11.6% (<48 mmol/mol), 23.3% (≥76 mmol/mol).
  • Adjusted relative risk rose in a dose–response manner: HbA1c <48 mmol/mol (aRR 3.4), 48–61 mmol/mol (aRR 4.6), 62–75 mmol/mol (aRR 5.7), ≥76 mmol/mol (aRR 6.3).
  • The term preeclampsia risk was 3.5 times higher in women with type 1 diabetes compared with women without diabetes.
  • The risk of early preterm preeclampsia (<34 weeks) was 7.2 times higher in women with type 1 diabetes.
  • Late preterm preeclampsia (34–36 weeks) was 9.9 times higher in women with type 1 diabetes.
  • Women with type 1 diabetes remained at a higher risk of preeclampsia even with HbA1c levels within guideline-recommended targets.
  • Optimal peri-conceptional glycaemic control was associated with the lowest risk of preeclampsia in women with type 1 diabetes.
The authors noted some limitations, including the fact that HbA1c values were typically recorded only once a year in the Swedish registry, potentially excluding some women with diabetes and introducing selection bias. Diagnosing preeclampsia in women with pre-existing kidney involvement, such as albuminuria, can also be complex due to overlapping symptoms. Sensitivity analyses, however, confirmed the robustness of the findings, even after excluding women with albuminuria or accounting for low-dose aspirin use, which can lower preterm preeclampsia risk. Another limitation was the absence of continuous glucose monitoring (CGM) data, which is now considered a more precise tool for managing diabetes in pregnancy.
Despite these caveats, the study provides strong evidence that type 1 diabetes is a major risk factor for preeclampsia, and that peri-conceptional glycaemic control plays a critical role in modifying that risk. The researchers stressed that while women with diabetes remain at elevated risk even when meeting guideline-recommended HbA1c targets, maintaining glucose levels as close to normal as possible around conception offers the best protection against preeclampsia, especially severe preterm forms.

taVNS Reduces Postpartum Uterine Contraction Pain After Cesarean Delivery: JAMA

China: Researchers have found in a new study that transcutaneous auricular vagus nerve stimulation (taVNS) appears to be a safe and effective therapy for reducing uterine contraction pain in women following cesarean delivery.

The trial, published in JAMA Network Open by Xingyu Xiong and colleagues from the Department of Anesthesiology at the Affiliated Hospital of Xuzhou Medical University in China, evaluated whether this non-invasive nerve stimulation technique could alleviate discomfort commonly experienced in the days after cesarean delivery. 
The randomized clinical trial enrolled 156 women aged 18 years or older who were scheduled for elective cesarean delivery under combined spinal-epidural anesthesia. Participants were assigned to either active taVNS or sham stimulation in a 1:1 ratio. Both groups received 30-minute sessions once daily on the day of surgery and on the first two postoperative days. The primary outcome measured was the rate of moderate to severe uterine contraction pain by the third day after surgery. Researchers also assessed incision pain, mood symptoms such as anxiety and depression, overall recovery quality, and sleep outcomes.
The findings of the study were as follows:
  • Only 5.1% of women in the taVNS group reported moderate to severe contraction pain on day three, compared with 28.2% in the sham group.
  • This represented an 82% relative risk reduction (relative risk, 0.18).
  • Participants in the taVNS group experienced less incision-related pain.
  • Women receiving taVNS reported lower levels of anxiety and depression.
  • Sleep quality was significantly better in the taVNS group compared to the sham group.
  • Overall recovery improvements were greater among taVNS participants.
  • The median depression score was 3 in the taVNS group compared with 5 in the sham group.
Postpartum uterine contraction pain is a common and often severe source of discomfort following cesarean delivery. Traditional pain management strategies frequently rely on medications, which may come with side effects or concerns about breastfeeding safety. The findings of this study suggest that taVNS, a non-pharmacological approach, could provide meaningful relief while also enhancing emotional well-being and recovery. “taVNS represents a novel, safe, and effective strategy for managing postpartum uterine contraction pain, with additional benefits for mood and recovery,” the authors concluded.
While the results are promising, the study had several limitations. Conducted at a single center and limited to women undergoing elective cesarean delivery, the findings may not be broadly generalizable. The trial also did not include objective biological measures, such as inflammatory markers, nor did it evaluate whether participants could correctly guess their treatment assignment, raising questions about potential bias. Furthermore, the optimal frequency and duration of taVNS sessions remain unclear and may vary between individuals.
“The randomized clinical trial provides encouraging evidence that taVNS can substantially reduce postpartum contraction pain and improve recovery in women after cesarean delivery. If validated in larger, multi-center studies, taVNS may become an important adjunctive option for postoperative pain management in obstetric care,” the authors wrote.

Millions of men could benefit from faster scan to diagnose prostate cancer: JAMA

A quicker, cheaper MRI scan was just as accurate at diagnosing prostate cancer as the current 30-40 minute scan and should be rolled out to make MRI scans more accessible to men who need one, according to clinical trial results led by UCL, UCLH and the University of Birmingham.

The PRIME trial, funded by the John Black Charitable Foundation and Prostate Cancer UK, and published in JAMA, confirms that a two-part MRI scan is just as effective at diagnosing prostate cancer, whilst cutting scan time to just 15-20 minutes and reducing the need for a doctor to be present.

The investigators say the results are likely to lead to changes in clinical practice, making MRI accessible to more men in the UK and beyond.

Prostate cancer is the most common cancer in men, with around 56,000 diagnoses and 12,000 deaths each year in the UK1. The introduction of MRI scans over the last decade, following work by UCL researchers, has been the biggest change in how prostate cancer is diagnosed for the past 30 years.

Abnormalities seen on the MRI scan allow targeted tissue biopsies to be taken that can improve cancer detection. A normal MRI result, which occurs in around a third of patients, is reassuring and allows men to avoid an unnecessary biopsy.

Despite the clear benefits of the MRI scan, in many healthcare settings around the world, men who need a scan still do not get one. For example, previous research has estimated that 35% of US prostate cancer patients received an MRI in 2022. In England and Wales, only 62% of men who needed a prostate MRI received one in 2019 (the most recent year for when data is available).

Associate Professor Veeru Kasivisvanathan, lead researcher and Chief Investigator on the trial from UCL Surgery & Interventional Science and UCLH, said: “Currently around four million MRI scans are needed each year globally to diagnose prostate cancer. This demand is set to rise rapidly with a predicted surge in prostate cancer cases over the next 20 years.

“Time, cost and staff availability are all limiting factors in how many scans can be offered, which makes the results of the PRIME trial particularly important. If we can do the scan in up to half the time, with fewer staff and at lower cost, that will make a huge difference in allowing every man who needs a scan to be able to get one in a timely fashion.”

In the study, cancer specialists from 22 hospitals in 12 countries across the world recruited 555 patients aged 59-70 to see whether a streamlined two-part ‘biparametric’ MRI could detect cancer at the same rate as a full three-part ‘multiparametric’ MRI, which is currently standard of care in the UK and includes a third stage where a dye is injected into the patient.

All patients underwent the full three-part scan. Radiologists then assessed the two-part scan without the dye, and separately assessed the three-part scan with the dye, for every patient. A prostate biopsy was done when required to confirm whether or not the diagnosis was correct.

Researchers from UCL and UCLH confirmed that the two-part scan was just as effective at diagnosing prostate cancer. In total, 29% of the patients had important prostate cancer diagnosed by the shorter two-part scan, the same percentage as the longer three-part scan.

Associate Professor Francesco Giganti, a lead radiologist on the trial from UCL Surgery & Interventional Science and UCLH, said: “The three-part multiparametric MRI scan has been a game-changer for the diagnosis of prostate cancer, sparing thousands of patients unnecessary biopsies and improving cancer detection.

“Currently we inject a dye into the patient that highlights the presence of cancer on the MRI scan, but this step requires time and the presence of a clinician, and can on rare occasion cause mild side effects.

“Being able to make accurate diagnoses without the contrast stage will reduce scan time meaning we can offer scans to more men using the same number of scanners and operators. However, it is vital that the scans are of optimal diagnostic quality and that they are interpreted by a radiologist with dedicated expertise in prostate MRI.”

As well as making the procedure more efficient in terms of time and personnel, a two-stage MRI would generate significant cost savings per scan. In the NHS currently, a three-phase MRI scan costs £273 on average3. At £145, a two-phase scan is 47% cheaper. In countries like the US where healthcare costs tend to be much higher, the savings are likely to be even greater.

Prostate Cancer UK’s TRANSFORM trial, the biggest prostate cancer screening trial for 20 years that will include MRI, is due to begin later this year. It will be jointly led by UCL researchers alongside collaborators from Imperial College London, The Institute of Cancer Research and Queen Mary University of London. The trial will find the best way to screen men for prostate cancer, achieving the evidence needed for the introduction of a national screening programme. The results of the PRIME trial are an important step towards realising this ambition.

Dr Matthew Hobbs, Director of Research at Prostate Cancer UK, said: “The results from the PRIME trial, showing that a faster, cheaper, type of prostate MRI is just as good as the current standard MRI at detecting prostate cancer, are a hugely important step in the right direction for making MRIs more efficient.

“Another trial is already happening in the UK and the results of the two trials together should provide the complete evidence package we need to change practice across the country. We encourage NICE to prepare to review their guidelines as soon as that evidence base is complete, so that we can make MRI quicker, cheaper and less onerous for men.

“Our funding for PRIME, alongside the John Black Charitable Foundation, also provided recommendations of a few simple ways for hospitals to improve scan quality. So, while we await a review by NICE, hospitals should use guidelines from UCL’s GLIMPSE trial, so that they are ready for the implementation of biparametric MRI if it’s recommended, and so that the men having MRI scans right now get the most accurate scan possible.”

Elevated CAR on POD3 Predicts Prolonged Hospital Stay After Advanced hepatobiliary or pancreatic surgery: Study

Researchers have found in a new study that an elevated C-reactive protein to albumin ratio (CAR) on postoperative day 3 was identified as an early independent predictor of prolonged postoperative length of stay (PPLOS). These findings underscore the importance of early monitoring and timely intervention using CAR to reduce PPLOS and minimize complication severity after advanced HBPS. This study was published in BMC Surgery by Masahiro F. and colleagues.

This single-center retrospective analysis included 737 patients who received highly sophisticated HBPS at Gifu University Hospital, Japan, from January 2010 through December 2023. Of these, 181 patients had severe postoperative complications within 30 days, which were graded as Clavien–Dindo grade III or IV. Predictive factors for PPLOS were assessed by univariate and multivariate analysis. The 75th percentile of postoperative length of stay was found to be 53 days, and patients with hospital stay greater than this were identified as having PPLOS.

Results

  • 45 patients developed PPLOS.

  • Univariate analysis showed intra-abdominal abscess, pancreatic fistula, postoperative bleeding, hepatic failure, unplanned intubation, CAR on POD3, and neutrophil-to-lymphocyte ratio (NLR) on POD3 as being significantly related to longer stay in hospital.

  • Multivariate analysis, however, disclosed that CAR on POD3 > 5.0 was an independent predictor of PPLOS with an odds ratio (OR) of 3.22 (95% confidence interval [CI]: 1.11–10.17; p = 0.03).

This research concluded that patients who had undergone highly complex HBPS with serious postoperative complications were at high risk for extended hospital stay. Of all perioperative factors under investigation, CAR on POD3 > 5.0 was the sole independent predictor of PPLOS. Researchers emphasized that early detection and targeted treatment on the basis of CAR could potentially lower extended hospital stays and counteract the adverse effects of critical complications on patient outcomes.

Oral vs. Topical TXA: Comparable Effectiveness and Safety in treatment of Melasma

Melasma is a chronic pigmentary disorder characterized by symmetric, hyperpigmented macules and patches on sun-exposed areas, most commonly the face. It disproportionately affects women and is associated with significant psychosocial distress. Among emerging therapies, tranexamic acid (TXA), an antifibrinolytic agent with anti-melanogenic properties, has gained attention as both an oral and topical treatment option. However, comparative data on route-specific efficacy and safety have remained limited.

A recent prospective study compared the effectiveness and safety profiles of oral and topical TXA in patients with moderate-to-severe melasma. Participants were randomly assigned to receive either oral TXA tablets or topical TXA formulations over a defined treatment period. Clinical improvement was evaluated using the Melasma Area and Severity Index (MASI), standardized digital imaging, and patient-reported outcomes. Safety was assessed through monitoring of adverse events and laboratory parameters. Results demonstrated that both oral and topical TXA significantly reduced MASI scores from baseline, with improvements visible within the first 8 weeks and sustained throughout the study duration. Patient satisfaction scores were similarly high in both groups, indicating clinically meaningful benefit regardless of administration route. Importantly, the incidence of adverse effects was low across both arms. Mild gastrointestinal discomfort was occasionally reported in the oral TXA group, while transient local irritation was observed in the topical TXA group. No serious adverse events or thromboembolic complications were reported, reinforcing the safety profile of both approaches. The findings suggest that oral and topical TXA offer comparable efficacy in melasma treatment, with similarly favorable safety outcomes. This provides clinicians with flexibility in tailoring treatment to patient preference, tolerability, and convenience. For patients reluctant to take systemic therapy, topical TXA represents a viable alternative, while oral TXA may be preferable for those seeking systemic benefits or with extensive involvement. Overall, this study supports the role of TXA as a versatile therapeutic agent in melasma management. Long-term studies with larger cohorts are warranted to confirm durability of response and further evaluate relapse rates post-treatment.

Cataract surgery on both eyes can be carried out safely and effectively in one go, reveals study

The results of two new studies show that it can be safe, effective and practical for most patients to have cataract surgery on both eyes in one day. Both studies will be presented at the 43rd Congress of the European Society of Cataract and Refractive Surgeons (ESCRS).

The first study, by Danish researchers, shows that the majority of patients can manage at home on their own after cataract surgery on both eyes, and carry out essential tasks such as preparing food and using their mobile phone.

The second study, by UK researchers, shows that patients receiving same-day cataract surgery on both eyes achieved visual outcomes as good as, or even better than those receiving treatment in two separate surgical procedures.

Cataract is a very common condition where the lens of the eye becomes cloudy, causing blurry vision and loss of sight. It can affect people at any age, but it becomes more common in older age. Cataract surgery, where the cloudy natural lens is replaced by an artificial lens, is one of the most common surgical procedures worldwide.

Cataracts often affect both eyes. Traditionally, when both eyes require cataract surgery, they are operated on separately, often weeks or months apart, a practice called delayed sequential bilateral cataract surgery. Increasingly, surgeons are offering immediate sequential bilateral cataract surgery, where both eyes are operated on during the same surgical session. But questions remain about whether this is as accurate and effective as delayed surgery, and how patients cope with day-to-day life immediately after surgery.

The Danish researchers, from Silkeborg Regional Hospital and Aarhus University Hospital, asked 157 patients who had undergone cataract surgery on both eyes on the same day to complete a questionnaire about their need for assistance immediately after they arrived home from surgery and again 24 hours later. A total of 72% of patients responded.

This showed that 88% of patients could find their way around the home independently, 79% managed to prepare food and 51% did not need help using their mobile phone, when they arrived home following surgery. On the other hand, 51% still needed help to use their eye drops. Sixty-two percent said they did not need a caregiver at all in the first 24 hours.

Speaking ahead of the Congress, ophthalmic nurse Mia Vestergaard Bendixen from Silkeborg Regional Hospital said: “There is very little research on patients’ self-sufficiency immediately after cataract surgery on both eyes in one day. Our results show that many people can expect to manage well soon after surgery, which may ease anxiety about needing support. However, some still benefit from a caregiver during the first day. For clinicians, these findings support offering same-day cataract surgery, while emphasizing patient education and planning for temporary help if needed. If surgery can be carried out in one go, this could reduce clinic visits and caregiver burden, as well as improving efficiency in healthcare delivery.”

The UK study, one of the largest of its kind, was carried out at Moorfields Eye Hospital NHS Foundation Trust in London. It included almost all patients having cataract surgery on both eyes at the hospital between December 2023 and December 2024, 10,192 in total.

Most were having delayed sequential bilateral cataract surgery (DSBCS), others were having immediate sequential bilateral cataract surgery (ISBCS). Some patients were having monofocal lenses, which provide sharp vision at one distance, others were having multifocal lenses, which split light to allow focus at multiple distances, aiming to reduce the need for reading or distance glasses.

The researchers analysed several different measures of vision in the patients following surgery, including whether they achieved excellent results, defined as 20/20 vision or better and a glasses prescription at or very near the intended target.

Patients receiving multifocal lenses with same-day surgery achieved the best overall visual outcomes, with 85% achieving 20/20 vision or better. In patients who received monofocal lenses, around 70% achieved 20/20 vision, regardless of whether they had surgery in both eyes on the same day or on different days. For patients having surgery on different days with multifocal lenses, the figure was 77%.

In terms of prescription accuracy, 88% of multifocal same-day patients were very near the target (within ±0.5 dioptres), while 67% of patients achieved this in the monofocal delayed group and 71% in the monofocal same-day group. One hundred percent of multifocal patients were near the target (within ±1.0 dioptre) regardless of whether they had surgery in both eyes on the same day or on different days.

The improved outcomes for multifocal same-day surgery remained even when researchers adjusted for patient age, gender, and the surgeon’s level of experience.

Speaking ahead of the Congress, Dr Gabriele Gallo Afflitto from Moorfields Eye Hospital NHS Foundation Trust said: “For patients, these findings are encouraging. They suggest that having cataract surgery performed in both eyes on the same day, particularly when combined with multifocal lens implantation, can deliver excellent vision, reduce dependence on glasses, and allow faster recovery.”

Mr Vincenzo Maurino, Consultant Ophthalmic Surgeon at Moorfields Eye Hospital NHS Foundation Trust, added: “For the patients and the hospital, this approach offers potential efficiency gains, including reduced waiting time, faster visual rehabilitation and fewer clinic appointments, as well as reduced waiting time and lower overall costs, all without compromising patient outcomes.”

Dr Joaquín Fernández, ESCRS Secretary, CEO of Qvision and Medical Director of Andalusian Ophthalmology Institute at Vithas Hospitals, Almería, Spain, who was not involved in the research, said: “There are many potential advantages to treating cataracts in both eyes in one go. Not only does it reduce hospital visits for patients, it also saves time for hospital staff, potentially allowing them to see more patients. However, we need to be sure that offering this approach maintains the highest standards of safety and does not increase the risk of surgical or postoperative complications.

“Taken together, these two studies show that cataract surgery to both eyes in one session can be performed safely, with patients recovering well at home and, crucially, achieving visual outcomes as good as or better than when surgery is performed in two steps. This should reassure patients, their families, and their surgeons that safety is not compromised.”
