Unintended Pregnancy After Kidney Transplantation

OBJECTIVE: To define risk factors, obstetric morbidity, and allograft outcomes associated with an unintended pregnancy after kidney transplant. METHODS: This is a retrospective cohort study of pregnancies in women after kidney transplantation enrolled in the Transplant Pregnancy Registry International with births between 1967 and 2019, with cohorts categorized as intended pregnancies and unintended pregnancies. The primary outcome was acute kidney rejection during pregnancy or by 6 weeks postpartum. Secondary outcomes included allograft loss, severe maternal morbidity, and neonatal composite morbidity. Multivariable logistic regression, Kaplan–Meier curves, and Cox proportional hazards regression models were performed, with adjustment for covariates pertinent to allograft function. RESULTS: Among 1,723 pregnancies of kidney transplant recipients, 1,081 (62.7%) were intended and 642 (37.3%) were unintended pregnancies. Risk factors for unintended pregnancy included younger age, Black race, nulliparity, chronic hypertension, and transplant from a deceased donor. Exposure to mycophenolate products (16.0% vs 5.7%) and termination (4.7% vs 0.4%) were more common in unintended pregnancies (P<.001). Unintended pregnancy was not associated with acute kidney rejection (2.3% vs 0.9%, adjusted odds ratio [AOR] 2.38, 95% CI, 0.91–6.30, P=.08). Unintended pregnancy was independently associated with allograft loss at 2 years from the end of pregnancy (8.1% vs 3.5%, AOR 2.27, 95% CI, 1.32–3.94, P=.003) but not allograft survival (adjusted hazard ratio 1.22, 95% CI, 1.00–1.49, P=.05). There were no differences in severe maternal morbidity (3.3% vs 3.6%) or neonatal composite morbidity (12.9% vs 14.3%) by pregnancy intention. CONCLUSION: Unintended pregnancy was not associated with acute kidney allograft rejection in the peripartum period, but it was associated with mycophenolate exposure and allograft loss at 2 years from pregnancy. The same social vulnerabilities that underlie difficulty in accessing reproductive care may be similarly important for transplant health. We recommend prepregnancy counseling and longitudinal follow-up of transplant recipients to reduce rates of unintended pregnancy and to optimize transplantation success over time.

Relationship between age and subfoveal choroidal thickness and its clinical implications

The retrospective study by Lei et al is an investigation of the relationship between age and subfoveal choroidal thickness (SFCT) in Chinese patients with proliferative diabetic retinopathy. Elements of the study design prevent the generalizability of the study findings, limiting their clinical implications. We recommend consideration of stricter eligibility criteria, other variables like duration of diabetes, interpretation of gender-differences in SFCT, longitudinal follow-up, use of newer choroidal flow indices, comparison of values with normal controls, subgroup analysis to determine the effect of prior treatment, as well as consideration of various real-world scenarios in future studies.

Prospective prediction of childhood body mass index trajectories using multi-task Gaussian processes.

Body mass index (BMI) trajectories have been used to assess the growth of children with respect to their peers, and to anticipate future obesity and disease risk. While retrospective BMI trajectories have been actively studied, models to prospectively predict continuous BMI trajectories have not been investigated. Using longitudinal BMI measurements between birth and age 10 y from a mother-offspring cohort, we leveraged a multi-task Gaussian process approach to develop and evaluate a unified framework for modeling, clustering, and prospective prediction of BMI trajectories. We compared its sensitivity to missing values in the longitudinal follow-up of children, compared its prediction performance to cubic B-spline and multilevel Jenss-Bayley models, and used prospectively predicted BMI trajectories to assess the probability of future BMIs crossing the clinical cutoffs for obesity. MagmaClust identified 5 distinct patterns of BMI trajectories between 0 to 10 y. The method outperformed both cubic B-spline and multilevel Jenss-Bayley models in the accuracy of retrospective BMI trajectories while being more robust to missing data (up to 90%). It was also better at prospectively forecasting BMI trajectories of children for periods ranging from 2 to 8 years into the future, using historic BMI data. Given BMI data between birth and age 2 years, prediction of overweight/obesity status at age 10 years, as computed from MagmaClust's predictions exhibited high specificity (0.94), negative predictive value (0.89), and accuracy (0.86). The accuracy, sensitivity, and positive predictive value of predictions increased as BMI data from additional time points were utilized for prediction. MagmaClust provides a unified, probabilistic, non-parametric framework to model, cluster, and prospectively predict childhood BMI trajectories and overweight/obesity risk. The proposed method offers a convenient tool for clinicians to monitor BMI growth in children, allowing them to prospectively identify children with high predicted overweight/obesity risk and implement timely interventions.

Longitudinal Follow-up Reveals Peripheral Immunological Changes Upon Tick Bite in a-Gal-Sensitized Individuals.

α-Gal syndrome is characterized by specific IgE (sIgE) antibodies to the carbohydrate galactose-α-1,3-galactose (α-Gal) and delayed onset of allergic symptoms after ingestion of mammalian meat. While tick bites are assumed to mediate sensitization, the immune response to tick bites has not yet been investigated. To investigate the peripheral immune response to tick bites in humans over time. In a longitudinal cohort study, immunological reactions associated with tick bites (Ixodes species) were analyzed within 1 day (V1), 2 weeks (V2), 1 month (V3), and 3 months (V4) after the occurrence of a bite. sIgE, sIgG, and sIgG subclass levels, as well as 10 cytokines, were quantified. Deep immune phenotyping was performed using mass cytometry. A total of 4 controls and 10 patients were bitten by a tick and followed up over 3 months. None of the controls developed sIgE to α-Gal, and sIgE increased in all patients from V1 until V2/V3, as did IL-8 levels. We noted a significant increase in CD19+ B cells and B-cell subpopulations, as well as a decrease in γδ CD56+ T cells in patients between V0 and V1. At V1, frequencies of plasmacytoid dendritic cells (pDCs) and γδ CD56+ T cells were lower in patients than in controls. Our study provides evidence of significant changes in several immune cell populations in α-Gal sensitized patients, along with increased levels of IL-8 and sIgE. This is the first exploratory study to investigate longitudinal peripheral immune profiles in patients and controls bitten by ticks.

Tobacco use, cirrhosis, and age are predictors of readiness to change and continued drinking following brief alcohol intervention in Veterans.

Alcohol-use disorder (AUD) is prevalent within the Veterans Health System, especially in patients being seen in hepatology clinics, and needs a point-of-care strategy. A brief alcohol intervention based on AUDIT-C (Alcohol Use Disorders Identification Test) may be needed for management of hazardous alcohol intake, but feasibility is unclear. We aimed to define predictors of readiness to cease alcohol intake (0-10, 10 being ready to quit now) and continued drinking after using a brief alcohol intervention in Veterans seen in hepatology clinics cross-sectionally and longitudinally over 6 months. A total of 414 men with liver disease (average age of 61 years old, 48% with cirrhosis, 31% with concomitant psychiatric conditions, 44% with tobacco use, 14% with prior AUD therapy) were approached. 144 patients (35%) had a positive AUDIT-C (8.9±4.0) and were given the brief intervention. 80 of these patients (56%) had a high readiness to change, listing "wanting to improve health" and "prior success at reducing alcohol intake" as their most frequent reasoning. On regression analysis, concomitant tobacco use was associated with a significantly lower readiness to quit alcohol score. On longitudinal follow-up at 6 months, 34 (23%) patients were still drinking. These patients were older, and more likely to have concomitant diagnoses of cirrhosis and anxiety. Overall, we found that in a large cohort of Veterans seen in hepatology clinics that in routine practice,a brief intervention targeted at alcohol use is feasible. Older patients with concomitant tobacco use, cirrhosis, and anxiety may need more longitudinal attention to ensure that the initial interest in reducing problem drinking is sustained.

Abstract 4138310: Successful Endovascular Closure of Ascending Aortic Pseudoaneurysm Using Atrial Septal Defect Occluder

Introduction: Ascending aortic pseudoaneurysms are mostly related to either surgery or non-surgical trauma. Any pseudoaneurysm arising from graft anastomoses, regardless of size or location, must be repaired due to the potential for catastrophic rupture. Traditional surgical intervention has a high mortality rate, but percutaneous treatment has emerged as an alternative. We present such a case of pseudoaneurysm treated by percutaneous intervention using a 6-mm Amplatzer device. Case: A 77-year-old female with a history of type A aortic dissection s/p emergent repair with a 32 mm tube graft one year ago presented with chest pain radiating to her back. Initial vital signs showed a BP of 185/105, SaO2 98% on RA, 98.3 F, HR 98 bpm, and RR 24/min. A chest CT scan suggested a pseudoaneurysm at the proximal anastomotic site of the aortic graft (Figs. 1A and B). Serial troponin and EKGs were unremarkable for acute ischemia. Multiple quaternary centers declined intervention due to the high risk of redo sternotomy for open repair and patient frailty. After multidisciplinary discussions, it was felt that percutaneous closure with an Amplatzer device was possible without coronary obstruction. In the catheterization lab, a TEE probe was placed to visualize the pseudoaneurysm of the ascending aorta (Fig. 1C). Angiography showed the aneurysm coming off the posterior aorta just above the noncoronary cusp, with the neck measuring ~6 mm (Fig. 1D). The aneurysm was successfully engaged using an 8-French sheath and an 8-French AL1. Based on measurements from the TEE and the angiogram, a 6 mm ASO device was used. After device deployment and release, aortograms showed that the pseudoaneurysm was excluded (Fig. 1H). Assessment with TEE and CTA showed no residual flow in the pseudoaneurysm (Fig. 1 E–G). Conclusion: Using an atrial septal occluder, endovascular intervention may be a safe and effective alternative to surgery for treating the ascending aortic pseudoaneurysm, especially in patients with a high prohibitive surgical risk. Longitudinal follow-ups are needed to comment on long-term mortality benefits for these individuals.

Who and how to screen for endogenous hypercortisolism in patients with mood disorders.

A strict association exists between mood disorders and endogenous hypercortisolism, namely Cushing's syndrome (CS). Indeed, CS is characterized by a wide range of mood disorders, such as major depression, generalized anxiety, panic disorders, bipolar disorders up to psychosis, with major depression being the most frequent, with a prevalence of 50-80%, and potentially representing the clinical onset of disease. Despite this observation, the exact prevalence of hypercortisolism in patients with mood disorders is unknown and who/how to screen for endogenous hypercortisolism among patients with mood disorders is still unclear. In this context, an accurate anamnestic and clinical examination are crucial in order to identify those patients who may benefit from CS screening. In particular, the presence of specific signs and symptoms of CS, comorbidities typically associated with CS, and lack of improvement of depressive symptoms with standard treatments can further guide the decision to screen for CS. Anyhow, it is noteworthy that mood disorders represent a cause of functional activation of hypothalamic-pituitary-adrenal (HPA) axis, a condition formerly known as non-neoplastic hypercortisolism (NNH). The differential diagnosis between CS and NNH is challenging. Beyond anamnestic and clinical features, various tests, including measurement of daily urinary cortisol and late-night salivary cortisol, together with low dose-dexamethasone suppression test, are used for initial screening. However, considering their low accuracy, a definitive diagnosis may require a longitudinal follow-up along with second-line dynamic tests like combined dexamethasone-CRH test and desmopressin test. In conclusion, available data suggest the need for a comprehensive assessment and follow-up of individuals with mood disorders to detect possible underlying CS, considering the pitfalls in diagnosis and the overlap of symptoms with other conditions like NNH. Specialized centers with expertise in CS diagnosis and differential testing are recommended for accurate evaluation and management of these patients.

Clinical features and progression of Parkinson's disease with LRRK2 variants: A prospective study.

We established a prospective cohort study to investigate the differences in motor and non-motor symptoms between idiopathic Parkinson's disease (IPD) and Parkinson's disease in carriers of leucine-rich repeat kinase 2 (LRRK2) gene risk variants (LRRK2-PD). The study included 1407 individuals with IPD and 649 individuals with LRRK2-PD (comprising 304 with LRRK2-G2385R, 220 with LRRK2-R1628P, and 105 with LRRK2-A419V). Differences in symptoms between LRRK2-PD and IPD were analyzed using LCMM modeling and Cox regression analysis. The LRRK2-G2385R variant showed slower progression in tremor symptoms and excessive daytime sleepiness compared with IPD. In contrast, symptoms associated with LRRK2-R1628P and LRRK2-A419V were more similar to those of IPD. Survival analysis revealed that LRRK2-PD does not affect life expectancy compared with IPD. Our extended longitudinal follow-up of LRRK2-PD in the Chinese population provided valuable insights, further confirming the clinical characteristics of the three LRRK2 variants.

Genetic variants for Alzheimer's disease and comorbid conditions.

Alzheimer's disease and related dementias (ADRD) frequently co-occur with comorbidities such as diabetes and cardiovascular diseases in elderly populations. Utilize a life-course approach to identify genetic variants that are associated with the co-occurrence of ADRD and another comorbid condition. Research data from African American participants of the Indianapolis-Ibadan Dementia Project (IIDP) linked with electronic medical record (EMR) data and genome-wide association study (GWAS) data were utilized. The age of onset for ADRD was obtained from longitudinal follow-up of the IIDP study. Age of onset for comorbid conditions was obtained from EMR. The analysis included 1177 African Americans, among whom 174 were diagnosed with ADRD. A semi-parametric marginal bivariate survival model was used to examine the influence of single nucleotide polymorphisms (SNPs) on dual time-to-event outcomes while adjusting for sex, years of education, and the first principal component of GWAS data. Targeted analysis of 20 SNPs that were reported to be associated with ADRD revealed that six were significantly associated with dual-disease outcomes, specifically congestive heart failure and cancer. In addition, eight novel SNPs were identified for associations with both ADRD and a comorbid condition. Using a bivariate survival model approach, we identified genetic variants associated not only with ADRD, but also with comorbid conditions. Our utilization of dual-disease models represents a novel analytic strategy for uncovering shared genetic variants for multiple disease phenotypes.

The introduction of a highly virulent PRRSV strain in pig farms is associated with a change in the pattern of influenza A virus infection in nurseries

The present study aimed to determine the dynamics of influenza A virus (IAV) infection in two endemically infected farms (F1 and F2), where a longitudinal follow-up of piglets was performed from birth to 8–12 weeks of age. During the study, a highly virulent isolate of porcine reproductive and respiratory syndrome virus (PRRSV) was introduced on both farms. This allowed us to examine the impact of such introduction on the patterns of infection, disease, and the antibody response of pigs to IAV infection. The introduction of the new PRRSV strain coincided with a change in the dynamics of IAV infection on both farms. In F1, the cumulative incidence of IAV increased from 20% before the outbreak to 67.5%, together with the existence of animals that tested positive for IAV (RT‒qPCR) in nasal swabs for two or more consecutive samples. In F2, the cumulative incidence of IAV increased from 50% before the PRRSV outbreak to 70%, and the proportion of prolonged IAV shedders increased sharply. Additionally, some animals were infected with the same IAV twice during the observation period. In contrast to previous reports, our study revealed that prolonged shedding was not related to the titres of maternally derived antibodies at the time of infection but was significantly (p < 0.05) related to PRRSV infection status. Notably, both before and after the PRRSV outbreak, a high proportion of IAV-infected piglets did not seroconvert, which was significantly (p < 0.05) related to the hemagglutination inhibition titres against IAV when infected.

Augmented Reality Versus Freehand Spinopelvic Fixation in Spinal Deformity: A Case-Control Study.

This study sought to compare screw placement accuracy and outcomes between freehand (FH) and AR-guided pelvic fixation. While pelvic fixation is a critical technique in spinal deformity surgery, S2-alar iliac (S2AI) screw placement poses challenges. We conducted a case-control study of 50 consecutive patients who underwent spinopelvic fixation at a single institution. AR guidance was performed using a head-mounted display (Xvision, Augmedics). Patient demographics, surgical characteristics, spinopelvic parameters, and screw breach grade were compared using univariate and multivariate statistics. Pelvic fixation was performed FH in 21 patients (median age, 64; female, 38.1%; median BMI 32.3kg/m2) and AR-guided in 29 patients (median age, 66; female, 51.7%; median BMI 28.4kg/m2). Mean follow-up was longer in the FH group (28 mos vs 11 mos, P < 0.001). Pelvic fixation in the FH group was performed using either S2AI (90.5%) or dual S2AI (9.5%) screws. There were no significant differences in length of surgery (FH, 439 minutes; AR, 490 minutes; P = 0.1) or estimated blood loss (FH, 2.1L; AR, 1.9L; P = 0.7). Accuracy of FH pelvic fixation was 95.6% (43/45 screws) and accuracy of AR pelvic fixation was 96.5% (55/57 screws). Multivariable logistic regression for screw breach revealed no significant association with AR guidance when controlling for age, BMI, osteoporosis, and smoking. We present the first case-control study of AR-guided spinopelvic fixation, with findings suggesting parity between FH and AR-guidance, serving as foundation for prospective controlled studies with longitudinal follow-up to interrogate the benefits of AR-guidance in spinal deformity surgery.

Mối tương quan giữa một số chỉ số trên cộng hưởng từ bó tháp trong tiên lượng khả năng phục hồi chức năng vận động ở bệnh nhân nhồi máu não vùng trên lều

Object: Correlation between some indices on pyramidal tract magnetic resonance in predicting motor function recovery in patients with supratentorial cerebral infarction. Method: Cross-sectional description with longitudinal follow-up includes 31 patients with supratentorial cerebral infarction within seven days and had an MRI at Bach Mai Hospital from January 2023 to December 2023. Result: The proportion of male patients with ischemic stroke predominated (61,3%). Hemiplegia was the most common symptom of ischemic stroke which damaged the path of the corticospinal tract. At three months after the stroke, no patient had severe NIHSS score ; the percentage of patients with mild and moderate NIHSS score was 61,3% and 38,7%, respectively. According to mRS, 25 patients (80,6%) recovered well after three months. The patient group, who had the axons did not go through the infarct lesion, had higher at rate of better motor function recovery after three months than the other groups who had the axons go through partly or completely inside the infarction lesion (respective rates were 64,5% and 16,1%); p&lt;0,05. FA index of the axons in the infarct side of the poor recovery group was smaller than the good recovery group, p&lt;0.05. Conclusion: The axonal signal, location versus the infarct lesion, and FA index of the axons in the infarct side are the factors that significantly predictive of motor recovery after three months in ischemic stroke patients.

Health related outcomes of patients with serious traumatic injury: Results of a longitudinal follow-up program delivered by trauma clinicians

IntroductionThe routine collection of long-term patient health outcomes after serious traumatic injury at the health service level is uncommon. In 2019, we implemented the longitudinal Trauma Service Follow Up (TSFU) program at a level I trauma centre. Delivered by the trauma service clinicians involved in inpatient care, it assesses quality of life and disability. This study reports the 6- and 12-month outcomes of the first two years of operation of the TSFU program. MethodsThis is a prospective cohort study of seriously injured adult trauma patients admitted to a level I trauma centre with 6- and 12-months post-discharge outcome assessments. Outcomes were quality of life and function/disability as measured using the EQ-5D-5L and WHODAS 2.0 validated instruments. Changes from 6 to 12 months were assessed using generalised estimating equations methods. Logistic regression models were used to identify factors associated with ongoing problems at each time point. ResultsFive-hundred and eight seriously injured patients were eligible for the TSFU program with follow-up rates over 80 % at both 6- and 12-month timepoints. At six months, ongoing problems with pain (69.9 %), anxiety and depression (49 %) and carrying out usual activities (57.5 %) were highly prevalent; at 12 months problems with pain (61.4 %) and anxiety and depression (43.8 %) persisted. Lower extremity and/or pelvic surgery was associated with ongoing pain, odds ratio (OR) = 3.77 (95 % CI 1.54–9.21, p=0.01), anxiety and depression (OR 1.95, 95 % CI 1.09–3.48, p=0.02) and problems carrying out their usual activities (OR 3.19, 95 % CI 0.75–13.5, p=0.11) at six months. These patterns mostly persisted at 12 months. Similar associations between surgical intervention and high levels of disability were evident at both time points. ConclusionPersistent impairments in physical and emotional health continues to affect many people following serious traumatic injury. The collection of longitudinal health outcomes by trauma clinicians enables identification of factors that contribute to disability and a reduction in quality of life. This in turn can drive quality improvement initiatives within the hospital trauma system. Longitudinal follow-up programs may provide a platform to provide ongoing specialist trauma-informed care after hospital discharge.

APOE ε4 and Dietary Patterns in Relation to Cognitive Function: An Umbrella Review of Systematic Reviews.

Carrying the apolipoprotein ε4 allele (APOE ε4) is the strongest genetic risk factor for late-onset Alzheimer's disease. There is some evidence suggesting that APOE ε4 may modulate the influence of diet on cognitive function. This umbrella review of systematic reviews evaluates the existing literature on the effect of dietary interventions on cognitive and brain-imaging outcomes by APOE status. PubMed, EMBASE, Web of Science, and Scopus were searched using terms appropriate to each area of research, from their respective starting dates of coverage until March 2023. Two independent reviewers conducted data extraction and performed a quality appraisal using the Measurement Tool to Assess Systematic Reviews (AMSTAR) 2. Six total reviews were included in the final analysis. Four reviews evaluated randomized controlled trials on individuals aged 50-93 years ranging the entire cognitive continuum. One review combined observational studies and clinical trials conducted on both cognitively healthy and cognitively impaired individuals (age range: 50-90), and 1 review included observational studies of both cognitively healthy and cognitively impaired adults (age range: 50-75). Both observational studies and clinical trials yielded inconclusive results attributed to both practical limitations associated with longitudinal follow-up and issues of methodological quality. Except for the Mediterranean diet, dietary interventions, such as the ketogenic diet, nutraceuticals, and supplements, were generally not effective in older APOE ε4 carriers. This review considers plausible biological mechanisms that might explain why older and cognitively impaired APOE ε4 carriers were less likely to benefit. This review identifies notable gaps in the literature, such as a shortage of studies conducted in middle-aged and cognitively healthy APOE ε4 carriers assessing the impact of dietary interventions and provides suggestions for novel trial designs.

Characteristics and treatment patterns of long-surviving patients with multiple myeloma: over 13 years of follow-up in the Connect® MM Registry

BackgroundOver the last 15 years, improvements in patient management and treatments have been associated with longer survival in patients with multiple myeloma (MM). The Connect MM Registry is a long-running, US, multicenter, prospective observational cohort study of patients with newly diagnosed MM (NDMM). We assessed the demographics, clinical characteristics, and treatment patterns of long-term survivors (LTS) enrolled in this registry. MethodsAdults with NDMM (N=3,011) were enrolled from 250 community, academic, and government sites across the US from 2009-2016. Baseline characteristics, treatment patterns, quality of life (QoL), and overall survival (OS) were examined among LTS, defined as patients with follow-up of ≥8 years after enrollment. ResultsAs of February 7, 2023, 518 patients were LTS and 2,493 were non-LTS. LTS were generally younger and had better performance status at enrollment compared with non-LTS. Most (65%) LTS received stem cell transplants and few (2%) experienced disease progression within 6 months of starting first line of therapy. At data cutoff, 63% of LTS were still on treatment at their most recent visit. QoL scores and QoL questionnaire completion rates were consistently higher among LTS than non-LTS. The estimated 8-year OS rate of all patients enrolled in the registry was 40%, comparable to an observed 8-year survival of 39% from the Surveillance, Epidemiology, and End Results (SEER) database. ConclusionThis analysis provides insights on long-surviving patients with MM using real-world data and therefore presents generalizability beyond data obtained in long-term follow-up of clinical trials, underscoring the need for longitudinal follow-up through registries.

Frontoparietal Structural Network Disconnections Correlate With Outcome After a Severe Stroke.

Structural disconnectome analyses have provided valuable insights into how a stroke lesion results in widespread network disturbances and how these relate to deficits, recovery patterns, and outcomes. Previous analyses have primarily focused on patients with relatively mild to moderate deficits. However, outcomes vary among survivors of severe strokes, and the mechanisms of recovery remain poorly understood. This study assesses the association between lesion-induced network disconnection and outcome after severe stroke. Thirty-eight ischaemic stroke patients underwent MRI brain imaging early after stroke and longitudinal clinical follow-up. Lesion information was integrated with normative connectome data to infer individual disconnectome profiles on a localized regional and region-to-region pathway level. Ordinal logistic regressions were computed to link disconnectome information to the modified Rankin Scale after 3-6 months. Disconnections of ipsilesional frontal, parietal, and temporal cortical brain areas were significantly associated with a worse motor outcome after a severe stroke, adjusted for the initial deficit, lesion volume, and age. The analysis of the underlying pathways mediating this association revealed location-specific results: For frontal, prefrontal, and temporal brain areas, the association was primarily driven by relatively sparse intrahemispheric disconnections. In contrast, the ipsilesional primary motor cortex, the dorsal premotor cortex, and various parietal brain regions showed a remarkable involvement of either frontoparietal intrahemispheric or additionally interhemispheric disconnections. These results indicate that localized disconnection of multiple regions embedded in the structural frontoparietal network correlates with worse outcomes after severe stroke. Specifically, primary motor and parietal cortices might gain particular importance as they structurally link frontoparietal networks of both hemispheres. These data shed novel light on the significance of distinct brain networks for recovery after a severe stroke.

Original salivary sex hormone data of naturally menstruating athletes and hormonal contraceptive users

ObjectivesThere is a lack of data on salivary sex hormones across the menstrual cycle (MC) or hormonal contraceptive (HC) cycle of elite athletes. We aimed to provide original data on salivary sex hormones (17β-estradiol, progesterone and free testosterone) in naturally menstruating female athletes with a regular cycle or irregular cycle and using combined HC. A secondary purpose was to compare these data with published data from the general population according to the menstrual status (MC or HC or irregularly menstruating).Methods367 saliva tests were performed on 44 elite athletes during 6 months of follow-up to certify for cycle regularity. Athletes were grouped into regular MC, n=13; irregular MC, n=5; and HC, n=26. We compared salivary data of regular MC across six cycle phases (menses, mid-follicular, late follicular, early luteal, mid-luteal and late luteal phases) with published data from women with a similar MC or HC status from the general population.ResultsWe provided salivary original data according to six sub-phases among elite athletes with regular MC. HC athletes showed lower salivary sex hormonal levels, markedly after the first week of active HC compared with regular MC. Athletes with irregular cycles do not show a progesterone rise from the first half to the second half of the cycle (Δirregular=0.38 (1.90), a rise detectable within regular MC group ΔregularMC=2.86 (2.88)).ConclusionsWe provided original data for salivary sex hormone levels in elite female athletes. These references may be valuable for research investigating MC or combined HC data, particularly in longitudinal follow-ups requiring repeated measurements.

Prostate Artery Embolization – Mid to Long-term Outcomes in 1075 Patients

BackgroundTo assess the mid to long-term safety and efficacy of Prostatic Artery Embolization (PAE) at a single-center, cohort of 1075 patients. MethodsThis IRB-approved retrospective-study included patients with moderate-to-severe Lower-Urinary-Tract-Symptoms(LUTS) or urinary-retention who underwent PAE from January-2014 to July-2023. Patients were assessed at 1, 3, 6, and 12-months post-PAE and yearly thereafter. International-Prostate-Symptom-Score(IPSS), Quality-of-Life(QoL) score, International-Index of Erectile-Function–5 score(IIEF-5), Prostate-Specific-Antigen(PSA), Prostate-volume(PV), Post-void-Residual(PVR), Benign-Prostatic-Obstruction(BPO)-medication usage, urinary-catheter status, and further prostate-interventions were assessed. Adverse-events were recorded and classified using the Society of Interventional-Radiology Adverse-Events(SIR-AE) severity classification. ResultsThe mean follow-up was 458.4±559.5 days. Mean age was 70.4±9.0 years, median(IQR) prostate-volume was 107gm(76-150), median pre-procedure IPSS, QoL, IIEF-5, and PSA were 23(18-28), 5(4-6), 17(10-21), and 4.7(2.6-8), respectively. In the LUTS subgroup, at 1-3, 6-12, and 48-60 months, the median-IPSS was 7(4-12, p<0.001), 6(3-11, p<0.001), and 9(4-15, p<0.001). The QoL was 2(1-2, p<0.001), 1(0-2, p<0.001), 2(0-3, p<0.001) at the same time-points. 119(94%) out of 126-patients in the retention cohort were catheter-free at the 3-month follow-up. Ninety-patients(16% of re-intervention eligible patients) required a second prostatic-intervention upto 60-months post-PAE. 65.5% of patients post-PAE were BPO-medication-free at 1-year. 7 patients (0.65%) had SIR-AE severity-Severe: transient ischemic-attacks:3, Urosepsis-2 (treated in inpatient-setting with IV-antibiotics), prostate-sloughing–2(needing TURP). All adverse events resolved without sequelae. ConclusionIn a large cohort with long-term longitudinal follow-up, PAE shows significant, sustained long-term relief of LUTS, improved QoL, low re-intervention rate, and high BPO medication-free rates. 94% of catheter-dependent patients at baseline were catheter-free at 3-months.

Do Children With Accidental Gunshot-related Fractures Experience Greater Risk of Mental Illness and Psychiatric Disorders? A Propensity-matched Study.

Firearm violence is the leading cause of death and is a major source of morbidity for children in the United States. While gunshot wounds (GSWs) are known to cause lasting psychological repercussions beyond physical injury, these effects are not well documented compared with the physical implications. Our study explores the association between accidental gunshot-related fractures in children and subsequent psychiatric outcomes. Relative to non-GSW-related fractures, do children sustaining an accidental GSW-related fracture experience higher risk of mental illness and psychiatric disorders? This study utilized the TriNetX US Collaborative Network as it provides comprehensive inpatient and outpatient data, longitudinal follow-up, and complete medical records across different facilities, closely reflecting real-world patient outcomes in orthopaedic practice. We retrospectively evaluated children diagnosed with an accidental GSW-related fracture and compared mental health diagnoses to children who experienced non-GSW-related fractures. Between January 1, 2003, and March 1, 2023, a total of 5071 children in the United States without preexisting anxiety, mood, psychotic, substance use, or insomnia disorders were reported to have experienced an accidental GSW-related fracture. Among these patients, 55% (2773) had a follow-up period of at least 1 year and met the inclusion criteria for the exposure cohort. In the non-GSW-related fracture cohort, a total of 61% (985,070) of children among 1,613,891 without the preexisting aforementioned conditions had a minimum follow-up period of 1 year and met the inclusion criteria. A total of 2769 children were successfully matched in each cohort using a greedy nearest neighbor propensity score-matching algorithm. Matching was based on age, gender, race, fracture location, and BMI, as these characteristics were identified through a regression analysis as potentially associated with psychiatric outcomes (p < 0.01). The mean ± SD age was 15 ± 4 years, and 16% (451) in the GSW cohort were girls. In the non-GSW cohort 17% (474) were girls. With respect to race and ethnicity, 62% (1709 in the GSW cohort; 1679 in the non-GSW cohort) were Black and 14% (384 in the GSW cohort; 386 in the non-GSW cohort) were Hispanic. Outcomes of interest were recorded for up to 3 years after the index event. The accidental GSW-related fracture cohort experienced a greater hazard of developing anxiety disorders (HR 3.8 [95% confidence interval (CI) 3.2 to 4.6]; p < 0.001), substance use disorders (HR 3.6 [95% CI 3.0 to 4.2]; p < 0.001), mood disorders (HR 2.4 [95% CI 1.9 to 3.1]; p < 0.001), non-mood psychotic disorders (HR 2.4 [95% CI 1.5 to 3.9]; p < 0.001), and insomnia (HR 1.8 [95% CI 1.4 to 2.3]; p < 0.001). Orthopaedic surgeons should implement early psychiatric screenings and integrate mental health support for children with gunshot-related fractures to address elevated risk of anxiety disorders, psychotic disorders, mood disorders, substance abuse, and insomnia. Future studies should focus on identifying effective interventions that mitigate these long-term psychological outcomes, with an emphasis on practical, targeted approaches in clinical care.
