  • Implant safety and implementation problems remain a concern

    What the study found

    The authors argue that surgical implants can bring serious risks, including complications with potentially devastating consequences. They also say that problems can arise not only from the implant itself, but from how new devices are tested, introduced, trained for, and monitored in everyday healthcare systems.

    Why the authors say this matters

    The authors suggest that better system-wide handling of implantable devices is needed if they are to achieve their intended clinical impact. They say that standardized early studies, whole-team training, funding support, and post-implementation reporting are important parts of that process.

    What the researchers tested

    This is an opinion paper based on the reflections of two surgical technologists. It discusses challenges in safety, efficacy, and broad implementation of medical implants, and it uses the IDEAL-D framework, which stands for Idea, Development, Exploration, Assessment, and Long-term study, as a reference point.

    What worked and what didn't

    The abstract says the IDEAL-D framework is an important step toward structuring medical-device studies. However, it also says that first-in-human use is not sufficiently standardized or regulated, and that once devices are approved for mainstream use, problems remain with adoption, funding, training, patient selection, and accurate reporting of complications.

    What to keep in mind

    This paper is an opinion piece rather than a study reporting new experimental data. Its scope is limited to the authors' reflections and the issues they describe in the abstract, and it does not provide detailed results from a specific implant trial.

    • The authors say surgical implants can cause serious complications.
    • They argue that first-in-human testing of new implants is not sufficiently standardized or regulated.
    • They identify implementation problems after approval, including training, funding, patient selection, and complication reporting.
    • The IDEAL-D framework is described as an important step for medical-device studies.
    • The authors say additional system-wide changes are needed beyond IDEAL-D.

  • Poor evidence quality found for follow-up reviews in preterm-born children

    What the study found

    The review found that the quality of systematic-review evidence on post-discharge follow-up in preterm-born children is poor. It also found that a preliminary screening step can reduce the time spent assessing low-quality reviews.

    Why the authors say this matters

    The authors conclude that better-quality evidence is needed for evidence-based guideline recommendations on follow-up of preterm-born children. They also suggest that preliminary screening improves efficiency by limiting assessment time spent on low-quality reviews.

    What the researchers tested

    The researchers conducted a mapping review, which is a structured way to identify and organize existing evidence. They searched MEDLINE, Epistemonikos, and the Cochrane database for systematic reviews published from 2010 to May 6, 2025 on interventions, prognosis, risks, incidence, prevalence, or diagnosis in preterm or very low birth weight children, and they applied quality criteria using AMSTAR 2 and ROBIS.

    What worked and what didn't

    Out of 8,000 references, 643 full texts were assessed and 239 systematic reviews met inclusion criteria. Among interventional reviews, seven were judged high- or moderate-quality, while in the prognosis and risk area, preliminary screening excluded 192 of 197 reviews and ROBIS identified two high-quality reviews out of five assessed after screening.

    What to keep in mind

    The abstract does not provide detailed limitations beyond the finding that overall evidence quality was poor. The review focused on systematic reviews that met specific inclusion criteria, so its results apply only to that set of evidence.

    • The review concludes that evidence for post-discharge follow-up in preterm-born children is poor.
    • 239 systematic reviews met the study's inclusion criteria.
    • Seven interventional reviews were rated high- or moderate-quality.
    • Preliminary screening excluded 192 of 197 prognosis and risk reviews before full ROBIS assessment.
    • The authors say preliminary screening can save assessment time by filtering out low-quality reviews.

  • Donation pledge reduced smartphone use and increased donations

    What the study found

    The Ulysses Donation Pledge, a low-friction digital self-control tool that lets users pledge donations for exceeding self-set screen time limits, reduced smartphone use in this pilot study. It also increased donations and raised satisfaction compared with baseline.

    Why the authors say this matters

    The authors suggest the approach may support digital well-being while better preserving user autonomy and self-regulation than more restrictive tools. They also say the findings call for further investigation of low-friction interventions as ways to empower users.

    What the researchers tested

    The researchers tested the Ulysses Donation Pledge over three weeks in a mixed experimental design with 45 participants. The intervention asked users to set their own smartphone screen time limits and pledge charity donations if they went over those limits.

    What worked and what didn't

    UDP significantly reduced smartphone usage compared with simple screen time restriction and control. It also produced a substantial increase in donations, and satisfaction increased significantly compared with baseline. The abstract does not report which parts did not work beyond noting that more restrictive tools are often abandoned.

    What to keep in mind

    This was a pilot study with a small sample and a three-week period, so the abstract does not establish long-term effects. The summary does not describe other limitations beyond the scope of the study.

    • The Ulysses Donation Pledge links smartphone overuse to donations to charity.
    • In a three-week pilot study with 45 participants, it significantly reduced smartphone use.
    • It led to a substantial increase in donations compared with restriction and control.
    • User satisfaction increased significantly compared with baseline.
    • The authors say the approach may preserve autonomy better than more restrictive digital self-control tools.

  • Patients reported challenges with orthodontic retention and retainer adherence

    What the study found

    The study found that patient experiences with orthodontic retention and retainers were shaped by several connected factors, including how patients lived with retainer wear and how they decided whether to follow retention instructions. The authors report three main themes: lived experience and impact of retainer wear, factors influencing adherence to retention protocols, and information, support, and decision-making systems.

    Why the authors say this matters

    The authors conclude that the findings provide important insights into patient experiences with orthodontic retention and retainers. They suggest that problems in shared decision-making, information delivery, and clinician-patient relationships were linked to more difficulty following retention protocols and lower satisfaction for many patients.

    What the researchers tested

    The researchers carried out a qualitative meta-ethnography, a method for combining findings from qualitative studies to interpret shared themes across them. They searched four databases up to 28 January 2026, included relevant mixed-methods and qualitative studies, and used two independent reviewers for study selection, data extraction, and quality appraisal with the Critical Appraisal Skills Programme tool for qualitative research.

    What worked and what didn't

    Out of 1,225 investigations identified, seven studies from four countries with 140 participants were included. The included studies, mostly about removable retainers, produced three main themes and eight sub-themes; the authors report that parental support became less important and reminder strategies less effective the longer patients were in the retention phase, while peer influence could be either supportive or demotivating depending on context.

    What to keep in mind

    The summary does not provide detailed limitations beyond the small number of included studies and participants. It also notes that the included investigations were published between 2019 and 2025 and mostly concerned removable retainers, so the findings may mainly reflect that context.

    • Seven studies from four countries were included in the meta-synthesis.
    • The included evidence covered 140 participants and mostly focused on removable retainers.
    • Three main themes were identified: lived experience, adherence factors, and information/support/decision-making systems.
    • Deficiencies in shared decision-making, information delivery, and clinician-patient relationships were linked to poorer adherence and satisfaction for many patients.
    • Parental support and reminder strategies appeared less effective as patients spent longer in retention.
    • Peer influence could help or hinder adherence depending on the situation.

  • Lingual attached gingiva is widest near molars and narrowest near incisors

    What the study found

    The study found that lingual attached gingiva, the band of gum tissue attached on the tongue side of the lower teeth, is widest around the molars and narrowest around the incisors in periodontally sound young adults. The authors also report no significant width differences between males and females.

    Why the authors say this matters

    The authors conclude that lingual attached gingiva has been relatively overlooked compared with buccal attached gingiva, the gum tissue on the cheek side of the teeth. They say the findings suggest this area deserves greater attention in periodontal research.

    What the researchers tested

    The researchers conducted a cross-sectional observational study of 120 people aged 18 to 30 years who were periodontally sound. They located the mucogingival junction, the boundary between attached gum and movable tissue, using rolling probe and visual methods on mandibular teeth and measured width with a UNC-15 periodontal probe.

    What worked and what didn't

    The greatest average width of lingual attached gingiva was reported at the first and second molars, at 5.85 mm ± 1.26 mm, while the narrowest average width was around the incisors, at 1.08 mm ± 0.65 mm. The central incisor had the smallest band at 0.54 mm ± 0.54 mm, and the first molar had the widest band at 5.97 mm ± 1.3 mm; widths ranged from 0 mm to 10 mm, and no significant sex differences were observed.

    What to keep in mind

    The study sample was limited to 120 periodontally sound individuals aged 18 to 30 years, so the findings apply to that group. The abstract does not describe other limitations.

    • Lingual attached gingiva was widest near the first and second molars.
    • The narrowest lingual attached gingiva was found near the incisors.
    • No significant difference in lingual attached gingiva width was seen between males and females.
    • The study included 120 periodontally sound participants aged 18 to 30 years.
    • The authors say lingual attached gingiva has been relatively overlooked in periodontal research.

  • Full-mouth rehabilitation improved esthetics and function in one open-bite case

    What the study found

    The case report describes a full-mouth rehabilitation for a 26-year-old woman with an anterior open bite and mild chronic generalized periodontitis. The authors report significant improvements in esthetics and function, with stability at 1 year of follow-up.

    Why the authors say this matters

    The authors present the case as showing the use of contemporary digital methods for diagnosis, modeling, and restoration fabrication in complex rehabilitation. They suggest the approach supported both esthetic and functional improvement.

    What the researchers tested

    This was a clinical case report of comprehensive full-mouth rehabilitation. The treatment used CAD software, a Kois deprogrammer, extraction of impacted molars, a cut-back technique, and artistic layering of ceramics on a lithium-disilicate framework.

    What worked and what didn't

    The report says the rehabilitation led to significant esthetic and functional improvement. It also states that the results remained stable after 1 year of follow-up.

    What to keep in mind

    This is a single clinical case, so the abstract does not show how the approach would perform in other patients. The available summary does not describe any failures, complications, or broader limitations beyond the case itself.

    • The article describes a full-mouth rehabilitation in a 26-year-old woman with an anterior open bite.
    • The patient also had mild chronic generalized periodontitis.
    • The treatment used digital methods, including CAD software, plus a Kois deprogrammer and ceramic fabrication on a lithium-disilicate framework.
    • The authors report significant improvements in esthetics and function.
    • The reported results were stable after 1 year of follow-up.

  • A2-typed kidneys labeled A1 by serology were transplanted safely

    What the study found

    The study found that kidneys from donors labeled as blood group A1 by serology, but confirmed as A2 by genotyping, were transplanted safely into ABO O and B recipients. The authors report favorable outcomes and no graft losses attributed to ABO incompatibility.

    Why the authors say this matters

    The authors conclude that using ABO genotyping, a genetic test that identifies blood group more precisely than serologic testing, could expand the donor pool for disadvantaged candidates. They also suggest this approach may reduce wait times by making more kidneys available for transplantation.

    What the researchers tested

    The researchers studied kidney transplants from donors labeled A1 by serology but genotyped as A2. Genotyping was done with real-time PCR or next-generation sequencing, and the team analyzed biopsy-proven rejection, anti-HLA and anti-ABO antibodies, and allograft loss.

    What worked and what didn't

    In this cohort, allograft survival was 100%. No graft losses were attributed to ABO incompatibility, and the abstract does not report graft losses from this cause.

    What to keep in mind

    The abstract does not provide detailed sample size, follow-up length, or comparative data against other donor-recipient groups. It also does not describe limitations beyond the available summary.

    • Kidneys labeled A1 by serology but confirmed as A2 by genotyping were transplanted to ABO O and B recipients.
    • The cohort had 100% allograft survival.
    • No graft losses were attributed to ABO incompatibility.
    • Genotyping was performed using real-time PCR or next-generation sequencing.
    • The authors support ABO genotyping as a routine supplement to serologic testing.

  • Donor ventilator duration was not linked to 1-year lung function

    What the study found

    The article reports that donor ventilation duration did not have a discernible effect on recipient lung function after lung transplantation. In the study described, recipients of lungs from donors ventilated for less than 5 days were compared with recipients of lungs from donors ventilated for more than 5 days.

    Why the authors say this matters

    The authors suggest these findings mean clinicians should not be quick to dismiss lung transplant donors because of ventilation time alone. They also note that donor ventilation time may no longer be a major selection factor in some allocation systems.

    What the researchers tested

    Fioretti et al. compared donors ventilated for less than 5 days with donors ventilated for more than 5 days. Their main outcome was lung function measured by spirometry, which is a test of how well the lungs move air, and they analyzed forced expiratory volume in 1 second at 1 year after transplant in a cohort of 588 patients.

    What worked and what didn't

    The study did not find any discernible effect on absolute or predicted forced expiratory volume in 1 second at 1 year posttransplant. The article says this is the most robust study on donor ventilation and recipient lung function to date, and it is consistent with prior data showing no association with overall survival.

    What to keep in mind

    The article notes that registry studies and single-center studies can be affected by survivorship bias, meaning they only include donors who reached organ offer and transplant. It also cautions that results from Alberta may not fully apply to more complex systems in Europe or the United States, where allocation rules and incentives differ.

    • Donor ventilation time was not associated with measurable differences in recipient lung function at 1 year.
    • The comparison was between donors ventilated for less than 5 days and more than 5 days.
    • The main lung function measure was forced expiratory volume in 1 second, assessed by spirometry.
    • The study included 588 patients.
    • The article says the findings are consistent with earlier survival data showing no effect of donor ventilation duration.

  • Ethical tensions emerge over CPR in brain-dead pediatric organ donors

    What the study found

    The article presents ethical disagreement over organ-preserving cardiopulmonary resuscitation, or OP-CPR, in a brain-dead pediatric organ donor. The case of a 12-year-old patient whose parents authorized organ donation led to concern when OP-CPR was ordered after cardiovascular collapse.

    Why the authors say this matters

    The authors conclude that the situation highlights tensions between organ availability, family intent, bodily integrity, and the dignity and personhood of the donor. They say clearer guidelines and better collaboration between pediatric intensive care teams and organ procurement organizations are needed, along with ethical frameworks for conscientious objection and conscientious commitment.

    What the researchers tested

    This Ethics Rounds article examines one clinical case and presents three perspectives on OP-CPR. The perspectives come from an ethicist working for an organ procurement organization, two pediatric intensive care attendings and bioethicists, and three nurses.

    What worked and what didn't

    One perspective argues that OP-CPR fits the family's intent and justice because it may increase organ availability. Another argues it may not be ethically justified because the chance of reaching the main goal is low, and it may harm the donor's dignity and personhood; concerns were also raised about communication and lack of explicit permission. The nurses describe communication problems, moral distress, and policy challenges connected to the practice.

    What to keep in mind

    The abstract describes a single case and a discussion of viewpoints, not an outcome study. It does not provide data on how often OP-CPR is used or whether it improves organ procurement in practice.

    • The article focuses on OP-CPR in a 12-year-old brain-dead organ donor.
    • The parents had authorized organ donation before cardiovascular collapse occurred.
    • An organ procurement director instructed staff to perform OP-CPR, which raised ethical concerns in the PICU team.
    • One view supports OP-CPR as consistent with family intent and justice because it may increase organ availability.
    • Other views question OP-CPR because of low likelihood of success, possible harm to dignity and personhood, and communication problems.
    • The authors call for clearer guidelines and better collaboration between care teams and organ procurement organizations.

  • Echocardiographic measures predicted poor outcomes in advanced-age PIHS

    What the study found

    Women aged 35 years or older with pregnancy-induced hypertension syndrome (PIHS) who had adverse pregnancy outcomes showed worse echocardiographic measurements than those with favorable outcomes. The study found that several heart-function indicators and clinical risk factors were associated with poorer outcomes.

    Why the authors say this matters

    The authors conclude that multi-parameter echocardiographic assessment may offer a reliable, non-invasive way to identify high-risk PIHS patients. They suggest this could support closer monitoring and timely intervention to improve maternal and fetal prognosis.

    What the researchers tested

    The researchers retrospectively studied 240 women aged 35 years or older diagnosed with PIHS between February 2019 and June 2022. They compared echocardiographic indicators, including ejection fraction, stroke volume, cardiac output, E/A ratio, early diastolic mitral annular velocity, E/E′ ratio, left atrial volume index, pulmonary venous flow velocities, and the Tei index, between women with favorable and adverse pregnancy outcomes.

    What worked and what didn't

    Women with adverse outcomes had significantly lower ejection fraction, stroke volume, cardiac output, E/A ratio, early diastolic mitral annular velocity, and reduced S- and D-wave velocities. They also had higher E/E′ ratio, left atrial volume index, Ar-wave velocity, and Tei index, and the differences were reported as statistically significant. A history of hypertension, nephritis, and a family history of hypertension were also identified as significant clinical risk factors.

    What to keep in mind

    This was a retrospective study, so the abstract does not describe randomized testing or direct proof of cause and effect. The summary also does not provide details on how adverse pregnancy outcomes were defined beyond grouping patients into favorable and adverse outcome groups.

    • 240 women aged 35 years or older with PIHS were included in a retrospective study.
    • Adverse outcomes were linked to lower ejection fraction, stroke volume, cardiac output, E/A ratio, and early diastolic mitral annular velocity.
    • Adverse outcomes were linked to higher E/E′ ratio, left atrial volume index, Ar-wave velocity, and Tei index.
    • History of hypertension, nephritis, and family history of hypertension were significant clinical risk factors.
    • A combined echocardiographic model had an AUC of 0.925 for predicting outcomes.
