IUD-related Uterine Perforation Incidence and Risk (Apex-IUD)
IUD insertion timing should be based on individual desire for IUD contraception and patient convenience to assure an IUD insertion can occur.
KEY FINDINGS: Although the risk for uterine perforation with IUD insertion 4 days to 6 weeks or less post partum is nearly seven times that of insertion non-post partum, perforation remains an incredibly rare event for all clinical time points. Despite a slight increased risk of perforation with breastfeeding at IUD insertion, the benefits of breastfeeding and effective contraception generally outweigh risks and should have little clinical impact. Therefore, IUD insertion timing should be based on individual desire for IUD contraception and patient convenience to assure an IUD insertion can occur. Careful follow-up of individuals at higher risk of uterine perforation is warranted.
BACKGROUND: Reports of perforation risk related to intrauterine devices (IUDs) inserted immediately post partum and among non-post-partum individuals are scarce, and previous studies with only 12-month follow-ups underestimate the risk. Breastfeeding at IUD insertion and insertion within 36 weeks post partum have been associated with increased risk of uterine perforation. The aim of these analyses was to compare the incidence and risks of IUD-related uterine perforations by non-post-partum and post-partum intervals at IUD insertion, and among post-partum individuals, to assess the impact of breastfeeding on these outcomes.
DETAILS: Performed a multisite cohort study in the USA, using electronic health records (EHR). Study sites were three health-care systems and a site that used data from a health-care information exchange. The study population included individuals who were aged 50 years or younger and had an IUD insertion between Jan 1, 2001, and April 30, 2018. Individuals were excluded if they had not been in the health-care system for at least 12 months before IUD insertion. The primary outcome for this analysis was any IUD-related uterine perforation diagnosis for the first IUD insertion in this time period. Both complete and partial IUD-related perforations were identified. Chart abstraction was done to validate EHR-based algorithms or confirm perforations. The crude rate and cumulative incidence of uterine perforation were evaluated by non-post-partum and post-partum intervals at IUD insertion in the full cohort, and by breastfeeding status in a subcohort of post-partum individuals. Cox models estimated crude and adjusted hazard ratios (aHRs). Data from 326,658 individuals in the full cohort and 94,817 individuals in the post-partum subcohort were analysed. In the full cohort, we identified 1008 uterine perforations (51.2% complete), with the 5-year cumulative incidence being the lowest in the non-post-partum group (0.29%, 95% CI 0.26-0.34). The aHR for the post-partum interval relative to non-post partum ranged from 2.73 (95% CI 1.33-5.63; 0 to 3 days post partum) to 6.71 (4.80-9.38; 4 days to >=6 weeks post partum). The post-partum subcohort of individuals with breastfeeding information had 673 uterine perforations (62% complete), with a 5-year cumulative incidence of 1.37% (95% CI 1.24-1.52) and an increased risk with breastfeeding (aHR 1.37, 95% CI 1.12-1.66).

Enhanced Recovery Protocols May Improve Outcomes After Pediatric Gastrointestinal Surgery When Adherence Is High
In the ENRICH-US trial of 597 children and adolescents undergoing gastrointestinal surgery, implementing an enhanced recovery protocol did not significantly reduce overall hospital length of stay. However, patients who received at least 13 protocol elements had stays that were 1.14 days shorter and lower odds of postoperative complications. The findings underscore the importance of consistent protocol adherence when translating enhanced recovery strategies into better surgical outcomes.
KEY FINDINGS: The ENRICH-US trial did not demonstrate a significant overall reduction in length of stay from introducing a multifaceted implementation strategy. However, patients receiving a greater number of protocol elements experienced shorter hospital stays and fewer complications. These findings emphasize that the clinical benefit of enhanced recovery pathways may depend on consistent delivery of their components, not simply on adopting a protocol. Hospitals implementing pediatric ERPs should therefore monitor adherence alongside clinical outcomes and address organizational barriers that limit reliable implementation.
BACKGROUND: Enhanced recovery protocols (ERPs) combine evidence-based perioperative practices to support recovery, reduce opioid exposure, and minimize complications after surgery. Although these protocols are well established in adult surgical care, their implementation in pediatric populations has been slower. The ENRICH-US trial evaluated whether a structured implementation strategy could improve adherence to a pediatric gastrointestinal surgery ERP and enhance clinical outcomes.
DETAILS: This prospective, stepped-wedge cluster-randomized implementation-effectiveness trial included 597 patients aged 10-18 years undergoing elective gastrointestinal surgery at 18 US sites between September 2019 and June 2024. The protocol included 21 perioperative elements, supported by a structured implementation toolkit, multidisciplinary learning sessions, adherence feedback, and implementation reports. Outcomes were assessed during baseline usual care, implementation, and sustainability phases. The primary clinical outcome was postoperative hospital length of stay (LOS). Secondary outcomes included time to resumption of a regular diet, inpatient opioid use, postoperative complications, opioid prescriptions at discharge, 30-day readmission, and patient-reported health-related quality of life.

Inflammatory bowel disease was the most common surgical indication, accounting for 433 patients (72.5%). Across the three study phases, the implementation strategy did not significantly reduce overall hospital LOS or produce significant differences in most secondary outcomes. However, patients resumed a regular diet sooner and had lower opioid use during hospitalization as the protocol progressed. A patient-level analysis demonstrated the importance of adherence. Patients who received at least 13 ERP elements had a median hospital stay that was 1.14 days shorter (95% CI, -2.01 to -0.27) and lower odds of postoperative complications (adjusted odds ratio, 0.48; 95% CI, 0.28-0.82) than patients with lower adherence. The median number of protocol elements delivered increased from 11 during baseline to 14 during both implementation and sustainability phases (P < .001).

Timing of Vascular Access Creation in Older Adults With ESKD
A prospective European cohort of older adults with ESKD found that only 32% of AVFs were created within the defined 6-month window before hemodialysis initiation, while 42% were created early and 26% late. The findings highlight the difficulty of predicting dialysis timing and the need for better tools to individualize vascular access planning.
KEY FINDINGS: In this European cohort of older adults with ESKD, vascular access creation frequently did not coincide with the timing of hemodialysis initiation. More than 4 in 10 AVFs were created early, while approximately 1 in 4 were created late, resulting in substantial use of CVCs at dialysis initiation. The findings highlight the difficulty of predicting dialysis initiation in older adults and support the development of clinical prediction tools to better individualize vascular access planning.
BACKGROUND: Planning vascular access for older adults with end-stage kidney disease (ESKD) is challenging because the timing of hemodialysis initiation is difficult to predict. Arteriovenous fistulas (AVFs) created too early may remain unused, whereas delayed creation can result in hemodialysis being initiated through a central venous catheter (CVC). This study evaluated the timing of vascular access creation relative to hemodialysis initiation in older patients across Europe.
DETAILS: This secondary analysis used data from the EQUAL cohort, a prospective observational study involving patients aged 65 years or older with stage 4 or 5 chronic kidney disease in six European countries. Patients were included when their estimated glomerular filtration rate fell below 15 mL/min/1.73 m², provided they received a vascular access and had at least 6 months of follow-up. AVF timing was categorized as early when hemodialysis did not begin within 6 months after AVF creation, on time when hemodialysis was initiated with an AVF within 6 months, and late when hemodialysis was initiated with a CVC before or within 6 months after AVF creation.

A total of 332 patients were analyzed. An AVF was the first vascular access in 221 patients (67%), while 111 patients (33%) initially received a CVC. Among those initially receiving a CVC, 53 patients (48%) subsequently underwent AVF creation. At dialysis initiation, 158 patients (54%) were using an AVF and 136 (46%) were using a CVC. Among the 274 patients who underwent AVF creation, access was created on time in 88 patients (32%), early in 114 (42%), and late in 72 (26%). Despite the high proportion of early AVF creation, most fistulas were eventually used, with 90% of patients initiating hemodialysis within 3 years after AVF creation.

Overdiagnosis of Papillary Thyroid Cancer in the United States
A US simulation study estimated that 72% to 94% of papillary thyroid cancer cases diagnosed between 1991 and 2019 were overdiagnosed. Reducing ultrasonography for nonpalpable thyroid nodules was modeled to substantially lower PTC incidence, with less than a 0.1% change in overall mortality. The findings highlight the potential role of reducing unnecessary imaging and diagnosis while recognizing that the estimates are model-based.
KEY FINDINGS: The findings indicate that PTC overdiagnosis remained substantial even after accounting for a possible underlying increase in true disease incidence. The modeling suggests that limiting unnecessary ultrasonography referrals for nonpalpable thyroid nodules could reduce detection of cancers unlikely to affect population mortality, potentially reducing unnecessary diagnoses and treatment-related burdens without a meaningful modeled increase in overall mortality. Because these findings are based on a simulation model rather than observed outcomes from an intervention, they should be interpreted as population-level estimates rather than evidence that reducing imaging is appropriate for individual patients.
BACKGROUND: Papillary thyroid cancer (PTC) incidence in the United States has increased substantially over recent decades, largely driven by detection of small, early-stage tumors, while population-level mortality has remained relatively stable. This pattern has raised concern that some thyroid cancers detected through imaging may never have become clinically significant. This study used a validated simulation model to estimate the extent of PTC overdiagnosis in the United States and examine the potential effects of reducing thyroid ultrasonography for nonpalpable thyroid nodules.
DETAILS: Researchers used the Papillary Thyroid Carcinoma Microsimulation Model (PATCAM) to evaluate PTC incidence among US adults aged 18 years or older from 1991 through 2019. The model accounted for changes in underlying thyroid cancer risk and estimated the proportion and absolute number of PTC cases considered overdiagnosed, defined in the model as cancers whose detection and treatment did not affect population mortality. The investigators also modeled the potential effects of reducing thyroid ultrasonography referrals for nonpalpable thyroid nodules.

Between 1991 and 2019, the model estimated that 72% to 94% of diagnosed PTC cases were overdiagnosed. The estimated proportion was 75% to 95% among women and 63% to 90% among men. The corresponding absolute rate of overdiagnosis was 13 to 17 per 100,000 women and 3 to 5 per 100,000 men, translating to an estimated 443,212 to 573,705 women and 107,804 to 154,504 men overdiagnosed with PTC during the 28-year period. The model further estimated that reducing thyroid ultrasonography for nonpalpable nodules by 33% would reduce PTC incidence in 2019 by 17%, from 18 to 15 per 100,000 individuals. A 67% reduction in ultrasonography was associated with a modeled 41% reduction in incidence, from 18 to 11 per 100,000. In both scenarios, the modeled change in overall mortality was less than 0.1%.

Manual Detorsion by Pediatric Emergency Physicians May Shorten Ischemia Time in Pediatric Testicular Torsion
A study found that manual detorsion performed by pediatric emergency physicians can shorten ischemia time in children with testicular torsion. The findings highlight the potential value of prompt bedside intervention while definitive surgical management is being arranged. Manual detorsion remains a temporizing measure and does not replace urgent surgery.
KEY FINDINGS: The study highlights manual detorsion as a potentially useful time-saving intervention in pediatric testicular torsion. Having trained pediatric emergency physicians perform the procedure may allow restoration of testicular blood flow sooner and reduce the interval to definitive treatment. Because testicular viability is time-dependent, incorporating prompt manual detorsion into emergency management may be clinically relevant when appropriate expertise is available. The procedure should be viewed as an emergency temporizing measure followed by definitive surgical management.
BACKGROUND: Testicular torsion is a time-sensitive urologic emergency in which prolonged interruption of testicular blood flow can result in irreversible ischemic injury. Although definitive management requires urgent surgical detorsion and orchiopexy, manual detorsion may provide temporary restoration of blood flow while the patient is being prepared for surgery. This study evaluated whether manual detorsion performed by pediatric emergency physicians could reduce the time that the testis remains ischemic in children with testicular torsion.
DETAILS: The study examined pediatric patients with suspected testicular torsion who underwent manual detorsion by pediatric emergency physicians before definitive operative management. The investigators assessed the time from emergency department presentation to restoration of testicular perfusion and compared outcomes according to whether manual detorsion was successfully performed. The analysis focused on the potential role of emergency physicians in initiating immediate treatment rather than waiting for transfer to the operating room. Manual detorsion was considered an adjunct to, rather than a replacement for, definitive surgical management.

Manual detorsion performed by pediatric emergency physicians was associated with a shorter duration of testicular ischemia before operative treatment. Successful bedside detorsion allowed restoration of perfusion to occur earlier than would have been possible if treatment had been deferred until surgical exploration. The findings support the potential value of emergency physicians performing manual detorsion promptly when pediatric testicular torsion is suspected, particularly when operating-room preparation or surgical consultation may introduce additional delays. Definitive surgical exploration remains necessary because manual detorsion does not reliably correct the underlying torsion or prevent recurrence.

Global Differences in Pediatric Trauma Care Linked to Markedly Higher Mortality in Lower-Resource Settings
An international study of 237 children undergoing trauma laparotomy across 85 hospitals in 32 countries found substantial differences in access to timely surgery, senior clinicians, and perioperative resources. Overall 30-day in-hospital mortality was 8%, but children treated in lower-HDI settings had nearly sixfold higher adjusted odds of postoperative death than those in upper-HDI settings. The findings highlight major global disparities in pediatric trauma care and the need for dedicated, appropriately resourced pediatric trauma pathways.
KEY FINDINGS: The study demonstrates substantial international variation in pediatric trauma laparotomy pathways, particularly in prehospital delays, access to senior surgical and anesthesia providers, and available resources. Although crude 30-day mortality was 8% overall, children treated in lower-HDI settings had nearly sixfold higher adjusted odds of postoperative death than those in upper-HDI settings. The findings highlight disparities across the entire trauma-care pathway rather than differences attributable solely to operative management. The authors emphasize the need for trauma systems specifically designed around the physiological, surgical, and developmental needs of children.
BACKGROUND: Traumatic injury is a major cause of death and disability among children and adolescents worldwide, yet pediatric trauma systems and access to specialized care vary substantially between countries. This international study examined differences in injury patterns, treatment pathways, operative care, and postoperative outcomes among children requiring emergency laparotomy after traumatic injury.
DETAILS: The study was a planned post-hoc analysis of the international, multicentre, prospective GOAL-Trauma cohort, which collected data between April 1 and December 31, 2024. Patients aged 18 years or younger with blunt or penetrating trauma who underwent laparotomy within 5 days of presentation were eligible. Hospitals were grouped according to the Human Development Index (HDI) of their setting. A total of 237 pediatric patients from 85 hospitals across 32 countries met the inclusion criteria. Of these, 110 patients were treated in lower-HDI settings, 89 in middle-HDI settings, and 38 in upper-HDI settings. The investigators assessed differences in time to presentation, decision-making and surgery, perioperative interventions, staffing, injury severity, and 30-day in-hospital mortality.

The timing of trauma care differed substantially across HDI groups. Median time from injury to presentation, decision to operate, and operation itself was significantly longer in lower-resource settings, with the greatest variation occurring before hospital arrival. Overall median time from injury to operation was 7.4 hours (IQR 3.5-18.8). There were also major differences in the resources available during surgery. A consultant or attending general surgeon was the most senior surgeon present for 59% of cases in lower-HDI settings, compared with 78% in middle-HDI and 97% in upper-HDI settings. Similarly, a consultant or attending anesthetist was present in 35%, 62%, and 95% of cases, respectively. The overall crude 30-day in-hospital mortality was 8% (19 of 237 patients). After adjustment for relevant factors, children treated in the lower-HDI group had substantially higher postoperative mortality than those in the upper-HDI group, with an adjusted odds ratio of 5.69 (95% CI 1.58-20.44; P=0.0079).
