Iatrogenic harm in functional neurological disorder.

Functional Neurological Disorder (FND) is continuing to gain increasing recognition globally as a valid and potentially treatable disorder. Iatrogenic harm towards patients with FND is significant however, and has been around for centuries. Despite advances in our understanding around the aetiology, pathophysiology, and treatment of FND, many aspects of such harm continue to persist. Avoidance of iatrogenic harm has been highlighted by clinicians as one of the most important therapeutic considerations in FND, however, the sources and range of potential harms, or indeed ways to mitigate them, have not been previously summarised. Using a combination of clinical and research experience and scoping review methodology, this review aims to describe the main sources of iatrogenic harm towards patients with FND, including harm from misdiagnosis, delayed diagnosis and treatment, direct harm from professional interactions, other stigma-related harms, harm related to diagnostic overshadowing and over-diagnosis of FND. We also describe some potential ways to address and prevent such harms, such as ways to reduce misdiagnosis with a focus on rule in signs, optimising teaching and communication, ensuring parity of FND with other medical conditions, and continued integration of patient and professional organisations.

Umbilical Cord Blood as an Alternative to Neonatal Blood for Complete Blood Count: A Comparison Study.

OBJECTIVE: To assess concordance between umbilical cord blood (UCB) and neonatal blood (NB) laboratory test results at birth. STUDY DESIGN: This retrospective study considered very preterm neonates (<32 weeks' gestational age) admitted to a tertiary neonatal intensive care unit from 2012 to 2023. Inclusion criteria required neonates with a complete blood count measured in both UCB and NB drawn within 2 hours after birth. Median hemoglobin (Hb) and hematocrit (Hct) concentrations were compared between UCB (venous samples) and NB (venous, arterial, or capillary samples). RESULTS: A total of 432 neonates with paired UCB and NB values were included in the study. Hb concentration in UCB was 14.7 g/dL (IQR 13.5-16.1 g/dL) compared with 14.8 g/dL (IQR 12.6-19.3 g/dL) in venous NB samples, 13.9 g/dL (IQR 12.9-15.3 g/dL) in arterial NB and 18.7 g/dL (IQR 16.6-20.8 g/dL) in capillary NB. The regression equation showed a correction factor of 1.08 for converting Hb values from UCB to venous NB. Median Hct concentration in UCB was 0.45 L/L (IQR: 0.41-0.49 L/L) compared with 0.48 L/L (IQR 0.43-0.54 L/L) in venous NB, 0.42 L/L (IQR 0.38-0.45 L/L) in arterial NB and 0.57 L/L, (IQR 0.51-0.63 L/L) in capillary NB. CONCLUSIONS: Hb and Hct concentrations measured in UCB are similar to those measured in venous blood in very preterm infants and are valid alternatives for NB tests at birth. Hb and Hct concentrations in arterial and capillary NB are respectively lower and higher compared with UCB measurements.

Systemic and iatrogenic factors contribute to the development of severe hypernatraemia in vulnerable inpatients.

OBJECTIVES: To determine all-cause in-hospital mortality associated with severe hypernatraemia and the causes, comorbidities, time to treatment, discharge destination and postdischarge mortality. DESIGN: Retrospective observational cohort study. PATIENTS: Severe hypernatraemia, (sodium concentration ≥ 155 mmol/L), at any time during a tertiary hospital admission in Melbourne, Australia, 1 January 2019 to 31 December 2019 (pre-COVID19). MEASUREMENTS: Deaths, Charlson Comorbidity Index (CCI), hypernatraemia causes, time to treatment, discharge destination. RESULTS: One hundred and one inpatients: 64 community-acquired, 37 hospital-acquired. In-hospital mortality was 38%, but cumulative mortality was 65% by 1 month after discharge, with only a minor further increase at 6 and 12 months. After adjusting for peak sodium concentration, the community acquired group had significantly reduced odds of in-hospital mortality (odds ratio 0.15, 95% confidence interval [0.04-0.54], p = .003). Iatrogenic factors were present in 57% (21/37) of the hospital-acquired group. Only 55% of all cases received active sodium directed treatment. Time to start treatment did not affect outcomes. High levels of comorbidity were present, median CCI (IQR) was 6 (5-8) in the community and 5 (4-7) in the hospital group. Dementia prevalence was higher in the community group, 66% (42/64) versus 19% (7/37) (p = .001). Infection was the most common precipitant with 52% (33/64) in the community and 32% (12/37) in the hospital group. Of the survivors, 32% who had been living independently required residential care after discharge. CONCLUSIONS: Mortality was high and loss of independence in survivors common. To potentially improve outcomes, hypernatraemia-specific guidelines should be formulated and efforts made to reduce system and iatrogenic factors.

Adequacy of thyroid hormone replacement for people with hypothyroidism in real-world settings: A systematic review and meta-analysis of observational studies.

OBJECTIVE: Thyroid hormone under-replacement and over-replacement are associated with adverse health outcomes. This systematic review aimed to evaluate the extent of thyroid hormone replacement adequacy for patients with known hypothyroidism in real-word settings, excluding those receiving thyroid hormone suppressive therapy as thyroid cancer treatment. DESIGN: Four electronic databases (Embase [Ovid], Medline [Ovid], PubMed and SCOPUS) were searched for published and unpublished observational studies until 12 December 2022. The results of the studies were meta-analysed to calculate pooled prevalence estimates for thyroid hormone supplementation adequacy, over-replacement and under-replacement. Quality assessment of studies was performed using the Joanna-Briggs appraisal tool for prevalence studies. RESULTS: Seven studies with a total of 4230 patients were eligible for quantitative synthesis. The pooled prevalence estimates of adequate thyroid replacement, over-replacement and under-replacement were 0.55 (95% confidence interval [CI]: 0.49-0.60, p = .001), 0.20 (95% CI: 0.14-0.27, p = .001) and 0.24 (95% CI: 0.13-0.36, p = .001), respectively. Four studies subclassified hypothyroidism and hyperthyroidism into overt and subclinical. The pooled prevalence of overt and subclinical hyperthyroidism was 0.04 (95% CI: 0.00-0.11, p = .01) and 0.17 (95% CI: 0.09-0.27 p = .001), respectively. For overt and subclinical hypothyroidism, the pooled prevalence was 0.02 (95% CI: 0.01-0.03, p = .001) and 0.20 (95% CI: 0.12-0.29, p = .001), respectively. CONCLUSIONS: On average, approximately half of patients with hypothyroidism are only treated to target euthyroidism. In real-world practice, a significant number of patients are over-treated or under-treated, leading to adverse healthcare outcomes. It is imperative that more effective thyroid monitoring strategies be implemented, with an emphasis on primary care thyroid function monitoring, to minimise inappropriate thyroid replacement treatments and optimise healthcare outcomes at a population level.

The substantial burden of iatrogenic vascular injury on the vascular surgery workforce at an academic medical center.

OBJECTIVE: Vascular surgeons are often called upon to provide emergent surgical assistance to other specialties for iatrogenic complications, both intraoperatively and in the inpatient setting. The management of iatrogenic vascular injury remains a critical role of the vascular surgeon, especially in the context of the increasing adoption of percutaneous procedures by other specialties. This study aims to characterize consultation timing, management, and outcomes for iatrogenic vascular injuries. METHODS: This study identified patients for whom vascular surgery was consulted for iatrogenic vascular complications from February 1, 2022, to May 12, 2023. Patient information, including demographic information, injury details, and details of any operative intervention, was retrospectively collected from February 1, 2022, to October 13, 2022, and prospectively collected for the remainder of the study period. Analyses were performed with R (version 2022.02.03). RESULTS: There were 87 patients with consultations related to iatrogenic vascular injury. Of these, 42 (46%) were female and the mean age was 59 years (±18 years). The most common consulting services were cardiology (32%), cardiothoracic surgery (26%), general surgery (8%), and neurointerventional radiology (10%). Reasons for consultation included hemorrhage (36%), limb ischemia (36%), and treatment of pseudoaneurysm (23%). A total of 24% of consults were intraoperative, 20% of consults related to extracorporeal membrane oxygenation cannulation, and 16% of consults related to ventricular assist devices including left ventricular assist device and intra-aortic balloon pump. The majority of these consult requests (60%) occurred during evening and night hours (5 PM to 7 AM). Emergent intervention was required in 62% of cases and consisted of primary open surgical repair of arterial injury (54%), endovascular intervention (21%), and open thromboembolectomy (15%). Overall, in-hospital mortality for the patient cohort was 20% and the reintervention rate was 23%, reflecting the underlying complexity of the illness and nature of the vascular injury in this patient group. CONCLUSIONS: Vascular surgeons play an essential role in managing emergent life-threatening hemorrhagic and ischemic iatrogenic vascular complications in the hospitalized setting. The complications require immediate bedside or intraoperative consult and often emergent open surgical or endovascular intervention. Furthermore, many of these require urgent management in the evening or overnight hours, and therefore the high frequency of these events represents a potential significant resource utilization and workforce issue to the vascular surgery workforce.

Diagnosis and management of secondary adrenal crisis.

Adrenal crisis (AC) is a life threatening acute adrenal insufficiency (AI) episode which can occur in patients with primary AI but also secondary AI (SAI), tertiary AI (TAI) and iatrogenic AI (IAI). In SAI, TAI and IAI, AC may develop when the HPA axis is unable to mount an adequate glucocorticoid response to severe stress due to pituitary or hypothalamic disruption. It manifests as an acute deterioration in multi-organ homeostasis that, if untreated, leads to shock and death. Despite the availability of effective preventive strategies, its prevalence is increasing in patients with SAI, TAI and IAI due to more frequent exogenous steroid administration, pituitary immune-related effects of immune checkpoint inhibitors and opioid use in pain management. The delayed diagnosis of acute AI which remains infrequently suspected increases the risk of AC. Its main precipitating factors are infections, emotional distress, surgery, cessation or reduction in GC doses, pituitary infarction or surgical cure of endogenous Cushing's syndrome. In patients not known previously to have SAI/TAI/IAI, recognition of its symptoms, signs, and biochemical abnormalities can be challenging and cause delay in proper diagnosis and therapy. Effective therapy of AC is rapid intravenous administration of hydrocortisone (initial bolus of 100 mg followed by 200 mg/24 h as continuous infusion or bolus of 50 mg every 6 h) and 0.9% saline. In diagnosed patients, preventive education in sick-day rules adjustment of glucocorticoid replacement and hydrocortisone parenteral self-administration must be performed repeatedly by trained health care providers. Strategies to improve the adequate preventive education in patients at risk for secondary AI should be promoted in collaboration with various medical specialist societies and patients support associations.

Systemic lupus erythematosus is associated with an increased frequency of spontaneous preterm births: systematic review and meta-analysis.

OBJECTIVE: Preterm birth is one of the most frequent complications of pregnancy in women with systemic lupus erythematosus. The high indicated preterm birth proportion due to hypertensive disorders of pregnancy and/or fetal growth restriction is well known, and preventive measures and screening for early detection are performed. The risk of spontaneous preterm birth is less well recognized. This study aimed to determine the proportions of spontaneous and indicated preterm birth in pregnancies of women with systemic lupus erythematosus. DATA SOURCES: A systematic literature search using Pubmed, Embase, Web of Science, and Google Scholar was performed in June 2021. STUDY ELIGIBILITY CRITERIA: Studies in pregnant women with systemic lupus erythematosus reporting spontaneous and indicated preterm birth rates were selected. Original research articles published from 1995 to June 2021 were included. METHODS: Quality and risk of bias of the included studies were assessed using the Newcastle-Ottawa quality assessment scale. To estimate the pooled event rates and 95% confidence intervals, meta-analysis of single proportions with a random-effects model was performed. RESULTS: We included 21 articles, containing data of 8157 pregnancies in women with systemic lupus erythematosus. On average, 31% (95% prediction interval, 0.14-0.50) of the pregnancies resulted in preterm birth, including 14% (95% prediction interval, 0.04-0.27) spontaneous and 16% (95% prediction interval, 0.03-0.35) indicated preterm birth. CONCLUSION: In pregnant women with systemic lupus erythematosus, spontaneous and indicated preterm birth proportions are high. This information should be applied in (prepregnancy) counseling and management in pregnancy. The knowledge obtained by this meta-analysis paves the way for further research of associated risk factors and development of interventions to reduce spontaneous preterm birth in systemic lupus erythematosus pregnancies.

Bladder trauma: a guideline of the guidelines.

OBJECTIVES: To identify and review the most up-to-date guidelines pertaining to bladder trauma in a unifying document as an updated primer in the management of all aspects relating to bladder injury. METHODS: In accordance with the PRISMA statement, the most recent guidelines pertaining to bladder injury were identified and subsequently critically appraised. An electronic search of PubMed and Scopus databases was carried out in September 2023. RESULTS: A total of six guidelines were included: European Association of Urology (EAU) guidelines on urological trauma (2023), EAU guidelines on paediatric urology (2022), Urotrauma: American Urological Association (AUA) (2020), Kidney and Uro-trauma: World Society of Emergency Surgery and the American Association for the Surgery of Trauma (WSES-AAST) guidelines (2019), Management of blunt force bladder injuries: A practice management guideline from the Eastern Association for the Surgery of Trauma (EAST) (2019), and EAU guidelines on iatrogenic trauma (2012). Recommendations were summarised with the associated supporting level of evidence and strength of recommendation where available. CONCLUSION: Several widely recognised professional organisations have published guidelines relating to the diagnosis, investigation, classification, management, and follow-up related to bladder injury. There is consensus amongst all major guidelines in terms of diagnosis and management but there is some discrepancy and lack of recommendation with regards to the follow-up of bladder injuries, iatrogenic bladder injury, paediatric bladder trauma, and spontaneous bladder rupture. The role of increasing minimally invasive techniques seem to be gaining traction in the select haemodynamically stable patient. Further research is required to better delineate this treatment option.

Parasomnias and sleep-related movement disorders induced by drugs in the adult population: a review about iatrogenic medication effects.

Parasomnias and sleep-related movement disorders (SRMD) are major causes of sleep disorders and may be drug induced. The objective of this study was to conduct a systematic review of the literature to examine the association between drug use and the occurrence of parasomnias and SRMD. Following Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines for reporting systematic reviews, we searched PubMed databases between January 2020 and June 2023. The searches retrieved 937 records, of which 174 publications were selected for full-text screening and 73 drugs were identified. The most common drug-induced parasomnias were nightmares and rapid eye movement (REM) sleep behaviour disorders and sleepwalking. In terms of drug-induced SRMD, restless legs syndrome, periodic limb movement disorders (PLMD), and sleep-related bruxism were most frequent. Medications that inhibit noradrenergic, serotonergic, or orexin transmission could induce REM sleep (e.g., nightmares). Regarding sleepwalking, dysregulation of serotoninergic neurone activity is implicated. Antipsychotics are mentioned, as well as medications involved in the gamma-aminobutyric acid (GABA) pathway. A mechanism of desensitisation-autoregulation of GABA receptors on serotoninergic neurones is a hypothesis. SRMD and PLMD could involve medications disrupting the dopamine pathway (e.g., antipsychotics or opioids). Opioids would act on mu receptors and increase dopamine release. The role of adenosine and iron is also hypothesised. Regarding bruxism, the hypotheses raised involve dysregulation of mesocortical pathway or a downregulation of nigrostriatal pathway, related to medications involving dopamine or serotonin. Parasomnias are rarely identified in drug product labels, likely due to the recent classification of their diagnoses. An analysis of pharmacovigilance data could be valuable to supplement existing literature data.

An international delphi survey and consensus meeting to define the risk factors for ureteral stricture after endoscopic treatment for urolithiasis.

PURPOSE: Iatrogenic ureteral strictures (US) after endoscopic treatment for urolithiasis represent a significant healthcare concern. However, high-quality evidence on the risk factors associated with US is currently lacking. We aimed to develop a consensus statement addressing the definition, risk factors, and follow-up management of iatrogenic US after endoscopic treatment for urolithiasis. METHODS: Utilizing a modified Delphi method, a steering committee developed survey statements based on a systematic literature review. Then, a two-round online survey was submitted to 25 experts, offering voting options to assess agreement levels. A consensus panel meeting was held for unresolved statements. The predetermined consensus threshold was set at 70%. RESULTS: The steering committee formulated 73 statements. In the initial survey, consensus was reached on 56 (77%) statements. Following in-depth discussions and refinement of 17 (23%) statements in a consensus meeting, the second survey achieved consensus on 63 (86%) statements. This process underscored agreement on pivotal factors influencing US in endoscopic urolithiasis treatments. CONCLUSIONS: This study provides a comprehensive list of categorized risk factors for US following endoscopic urolithiasis treatments. The objectives include enhancing uniformity in research, minimizing redundancy in outcome assessments, and effectively addressing risk factors associated with US. These findings are crucial for designing future clinical trials and guiding endoscopic surgeons in mitigating the risk of US.

Ureteral stricture rate after endoscopic treatments for urolithiasis and related risk factors: systematic review and meta-analysis.

PURPOSE: We aimed to accurately determine ureteral stricture (US) rates following urolithiasis treatments and their related risk factors. METHODS: We conducted a systematic review and meta-analysis following the PRISMA guidelines using databases from inception to November 2023. Studies were deemed eligible for analysis if they included ≥ 18 years old patients with urinary lithiasis (Patients) who were subjected to endoscopic treatment (Intervention) with ureteroscopy (URS), percutaneous nephrolithotomy (PCNL), or shock wave lithotripsy (SWL) (Comparator) to assess the incidence of US (Outcome) in prospective and retrospective studies (Study design). RESULTS: A total of 43 studies were included. The pooled US rate was 1.3% post-SWL and 2.1% post-PCNL. The pooled rate of US post-URS was 1.9% but raised to 2.7% considering the last five years' studies and 4.9% if the stone was impacted. Moreover, the pooled US rate differed if follow-ups were under or over six months. Patients with proximal ureteral stone, preoperative hydronephrosis, intraoperative ureteral perforation, and impacted stones showed higher US risk post-endoscopic intervention with odds ratio of 1.6 (P = 0.05), 2.6 (P = 0.009), 7.1 (P < 0.001), and 7.47 (P = 0.003), respectively. CONCLUSIONS: The overall US rate ranges from 0.3 to 4.9%, with an increasing trend in the last few years. It is influenced by type of treatment, stone location and impaction, preoperative hydronephrosis and intraoperative perforation. Future standardized reporting and prospective and more extended follow-up studies might contribute to a better understanding of US risks related to calculi treatment.

Iatrogenic cerebral amyloid angiopathy in older adults.

BACKGROUND AND PURPOSE: An increasing number of cases of iatrogenic cerebral amyloid angiopathy (CAA) have now been reported worldwide. Proposed diagnostic criteria require a history of medical intervention with potential for amyloid-ß transmission, for example those using cadaveric dura mater or requiring instrumentation of the brain or spinal cord. Clinical presentation occurs after an appropriate latency (usually three or four decades); to date, most patients with iatrogenic CAA have had 'early-onset' disease (compared to sporadic, age-related, CAA), as a consequence of childhood procedures. RESULTS: We describe five cases of possible iatrogenic CAA in adults presenting in later life (aged 65 years and older); all had prior neurosurgical interventions and presented after a latency suggestive of iatrogenic disease (range 30-39 years). Use of cadaveric dura mater was confirmed in one case, and highly likely in the remainder. CONCLUSION: The presentation of iatrogenic CAA in older adults widens the known potential spectrum of this disease and highlights the difficulties of making the diagnosis in this age group, and particularly in differentiating iatrogenic from sporadic CAA. Increased vigilance for cases presenting at an older age is essential for furthering our understanding of the clinical phenotype and broader implications of iatrogenic CAA.

Cerebral amyloid angiopathy decades after red blood cell transfusions: a report of two cases from a prospective cohort.

BACKGROUND AND PURPOSE: Patients who underwent red blood cell (RBC) transfusion from donors who later developed multiple spontaneous intracerebral hemorrhages (ICHs) have recently been identified to have increased risk of ICH themselves. This increased risk of ICH was hypothesized to be related to iatrogenic cerebral amyloid angiopathy (iCAA) transmission. Two cases are presented who had RBC transfusion as an infant and presented with CAA at a relatively young age decades later. METHOD: Cases were identified by prospectively asking all patients at our CAA outpatient clinic (November 2023 to January 2024) about a medical history with RBC transfusion or history with a high likelihood for RBC transfusion (e.g., hemolytic disease, trauma with massive hemorrhage). Eligible patients were all diagnosed with CAA, CAA with concomitant hypertensive arteriopathy or iCAA, and without hereditary CAA. RESULTS: Between November 2023 and January 2024, 2/35 (6%, 95% confidence interval 2%-19%) outpatient clinic patients had a history of RBC transfusion and none had a high likelihood medical history. The cases presented at age 47 and 57 and had already developed severe CAA. CONCLUSIONS: Red blood cell transfusion might be a possible mechanism for iCAA; however, further prospective data collection and experimental evidence concerning blood transmission of amyloid-ß are needed.

Risk factors and management of iatrogenic colorectal perforation in diagnostic colonoscopy: a single-center cohort study.

BACKGROUND AND AIMS: Diagnostic colonoscopy plays a central role in colorectal cancer screening programs. We analyzed the risk factors for perforation during diagnostic colonoscopy and discussed the treatment outcomes. METHODS: We performed a retrospective analysis of risk factors and treatment outcomes of perforation during 74,426 diagnostic colonoscopies between 2013 and 2018 in a tertiary hospital. RESULTS: A total of 19 perforations were identified after 74,426 diagnostic colonoscopies or sigmoidoscopies, resulting in a standardized incidence rate of 0.025% or 2.5 per 10,000 colonoscopies. The majority (15 out of 19, 79%) were found at the sigmoid colon and recto-sigmoid junction. Perforation occurred mostly in less than 1000 cases of colonoscopy (16 out of 19, 84%). In particular, the incidence of perforation was higher in more than 200 cases undergoing slightly advanced colonoscopy rather than beginners who had just learned colonoscopy. Old age (≥ 70 years), inpatient setting, low body mass index (BMI), and sedation status were significantly associated with increased risk of perforation. Nine (47%) of the patients underwent operative treatment and ten (53%) were managed non-operatively. Patients who underwent surgery were often diagnosed with delayed or concomitant abdominal pain. Perforations of rectum tended to be successfully treated with endoscopic clipping. CONCLUSIONS: Additional precautions are required to prevent perforation in elderly patients, hospital settings, low BMI, sedated patients, or by a doctor with slight familiarity with endoscopies (but still insufficient experience). Endoscopic treatment should be actively considered if diagnosis is prompt, abdominal pain absent, and especially the rectal perforation is present.

Blood over-testing: impact, ethical issues and mitigating actions.

Plenty of studies demonstrate that hospital-acquired anemia (HAA) can increase transfusion rates, mortality, morbidity and cause unnecessary patient burden, including additional length of hospital stay, sleep disruption and venipuncture harms resulting from blood samples unlikely to change clinical management. Beyond patient costs, community costs should also be considered, such as laboratory time and resources waste, environmental impact, increasing pressure on labs and fewer tests available on time for patients who can benefit from them most. Blood over-testing does not support the principles of non-maleficence, justice and respect for patient autonomy, at the expense dubious beneficence. Reducing the number and frequency of orders is possible, to a certain extent, by adopting nudge strategies and raising awareness among prescribing doctors. However, reducing the orders may appear unsafe to doctors and patients. Therefore, reducing blood volume from each order is a better alternative, which is worth implementing through technological, purchasing and organizational arrangements, possibly combined according to need (smaller tubes, adequate analytic platforms, blind dilution, blood conservative devices, aggregating tests and laboratory units).

An in-vitro three-dimensional surgical simulation technique to predict tibial tunnel length in transtibial posterior cruciate ligament reconstruction.

BACKGROUND: During the transtibial posterior cruciate ligament (PCL) reconstruction, drilling depth excessively longer than the tibial tunnel length (TTL) is an important reason to cause popliteal neurovascular bundle injury when preparing the tibial tunnel. This study aims to develop an in-vitro three-dimensional surgical simulation technique to determine the TTL in anteromedial (AM) and anterolateral (AL) approaches. METHODS: A total of 63 knees' 3-dimensional (3D) computed tomography models were included in this study. The SuperImage system was used to reconstruct the 3D knee model and locate the tibial PCL site. The established 3D knee model and the coordinates of the tibial PCL site were imported into Rhinoceros 3D modeling software to simulate AM and AL tibial tunnel approaches with different tibial tunnel angles (TTA). The TTL and the tibial tunnel height (TTH) were measured in this study. RESULTS: In AM and AL tibial tunnel approaches, the TTL showed a strong correlation with the TTA (for AM: r = 0.758, p < 0.001; for AL: r = 0.727, p < 0.001). The best fit equation to calculate the TTL based on the TTA was Y = 1.04X + 14.96 for males in AM approach, Y = 0.93X + 17.76 for males in AL approach, Y = 0.92X + 14.4 for females in AM approach, and Y = 0.94X + 10.5 for females in AL approach. CONCLUSION: Marking the TTL on the guide pin or reamer could help to avoid the drill bit over-penetrated into the popliteal space to damage the neurovascular structure.

Endoclip combined with colonic transendoscopic enteral tubing: a new approach for managing iatrogenic colonoscopy perforation.

BACKGROUND: Iatrogenic colonoscopy perforation (ICP) is a rare but most serious complication during colonoscopy investigation. However, endoscopic closure plays an important role in the dealing with ICP with the development of endoscopic techniques presently, there are still some portion of patients transferred to surgery. METHODS: Once a perforation was detected, endoclips were used to closed the defect of the colon. Then a colonic TET was planted inside the colon. The terminal end of the TET was put proximally to or near the location of the perforation. Then gas and fluid was sucked out through the TET with a syringe every 4 h. RESULTS: Three cases were treated with endoclip closure and colonic TET drainage. Case 1 was caused by urgent immediate perforation during routine colonoscopy, case 2 was delayed perforation after snare resection, and case 3 was ESD-related perforation. All patients got healed, no one transferred to surgery. CONCLUSIONS: A combination of endoclip closure and colonic TET drainage might be an easy and potential method in the dealing with different types of ICP. This study may offer a novel paradigm for addressing endoscopy-related intestinal perforations.

Making a Bad Situation Worse: Current and Potential Unintended Consequences of Juvenile Registration for Sexual Offences.

Within the US, children and adolescents who engage in sexually abusive behavior are often subjected to sex offender registration and notification requirements, which contribute to stigmatization and forfeiture of their civil rights without empirical basis (Lancaster, 2011; Pickett et al., 2023; Zilney & Zilney, 2009). To date, 39 states subject children with adjudicated sexual offenses to sex offender registration requirements, with most recent estimates revealing that approximately 200,000 youth have been placed on sex offender registries within the US and many are now on the registry as adults (Pickett et al., 2020). This severe response-by both members of the public and policymakers-toward children who engage in inappropriate sexual behavior is imposed upon children and adolescents with adjudicated sexual offenses in an effort to meet goals of reducing sexual violence and increasing community safety. Within the current discourse, we review the history of registration and notification practices for adolescents with sexual offenses, describe what registration and notification policies entail, and then present empirical and theoretical evidence of the harmful outcomes associated with implementation of registration and notification requirements for sexual offenses. Thus, the predominant aim of this discourse is to encourage thoughtful and critical examination of registration and notification policies and their iatrogenic impacts.

The first autopsy case of Epstein-Barr virus-positive marginal zone lymphoma that deteriorated after COVID-19 vaccination.

This is the first autopsy case of Epstein-Barr virus-positive marginal zone lymphoma (EBV + MZL) with an other iatrogenic immunodeficiency-associated lymphoproliferative disorders (LPD) (methotrexate [MTX]-associated LPD) that deteriorated after the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccine. This case had a unique immunophenotype. A 71-year-old female patient with rheumatoid arthritis receiving MTX presented with fatigue 1 week after the SARS-CoV-2 vaccination. She was hospitalized due to hepatorenal dysfunction and pancytopenia. Computed tomography revealed systemic lymphadenopathy. Her physical condition deteriorated, and the patient died. The autopsy revealed systemic lymphadenopathy comprising medium-sized atypical lymphocytes and scattered Hodgkin/Reed-Sternberg (H/RS)-like cells. An immunohistochemical examination showed that atypical lymphocytes were positive for CD79a and MUM-1 and some were positive for CD20 and IRTA-1. H/RS-like cells were immunoreactive for CD30 and CD15 and ringed by T cells. Both cell types were positive for EBV-encoded small RNA. The majority of H/RS-like cells were positive for CD20, whereas a small number of CD3-positive cells were admixed. We herein presented the first autopsy case of EBV + MZL that deteriorated after the SARS-CoV-2 vaccination.

Trends in preterm birth in the Netherlands in 2011-2019: A population-based study among singletons and multiples.

INTRODUCTION: Preterm birth (PTB) is the leading cause of infant mortality and morbidity worldwide. Rates of PTB in the Netherlands are declining, possibly due to the implementation of preventive strategies. In this study we assessed the overall trend in PTB rates in the Netherlands in recent years, and in more detail in specific subgroups to investigate potential groups that require scrutiny in the near future. MATERIAL AND METHODS: Based on the national perinatal registry, we included all pregnancies without severe congenital abnormalities resulting in a birth from 24 to 42 completed weeks of gestation between 2011 and 2019 in the Netherlands. We assessed PTB rates in two different clinical subtypes (spontaneous vs. iatrogenic) and in five gestational age subgroups: 24-27+6 weeks (extreme), 28-31+6 weeks (very), 32-33+6 weeks (moderate, 34-36+6 weeks [late] and, in general, 24-36+6 weeks [overall PTB]). Trend analysis was performed using the Cochran Armitage test. We also compared PTB rates in different subgroups in the first 2 years compared to the last 2 years. Singleton and multiple gestations were analyzed separately. RESULTS: We included 1 447 689 singleton and 23 250 multiple pregnancies in our study. In singletons, we observed a significant decline in PTB from 5.5% to 5.0% (p < 0.0001), mainly due to a decrease in iatrogenic PTBs. When focusing on different gestational age subgroups, there was a decrease in all iatrogenic PTB and in moderate to late spontaneous PTB. However, in spontaneous extreme and very PTB there was an significant increase. When assessing overall PTB risk in different subgroups, the decline was only visible in women with age ≥25 years, nulliparous and primiparous women, women with a medium or high socioeconomic status and hypertensive women. In multiples, the rate of PTB remained fairly stable, from 52.3% in 2011 to 54.1% in 2019 (p = 0.57). CONCLUSIONS: In the Netherlands, between 2011 and 2019, PTB decreased, mainly due to a reduction in late PTB, and more in iatrogenic than in spontaneous PTB. Focus for the near future should be on specific subgroups in which the decline was not visible, such as women with a low socioeconomic status or a young age.
