The effect of parental age on child development at 36 months: Insights from the Japan environment and children's study.

BACKGROUND: The impact of parent-childbearing age on child development at 36 months of age is controversial. AIMS: We used data from a large cohort study with multiple imputation and mediation analyses of variables. METHODS AND PROCEDURES: A total of 72,606 parent-child pairs from the Japan Environment and Children's Study were included in the study. Parents' ages were categorized into five groups. We used five domains of the Japanese translation of the Ages and Stages Questionnaire, Third Edition (J-ASQ-3). Scores below the cutoff value at 36 months were defined as developmental delays in each domain. We used three logistic analysis models. In Model 3, we analyzed maternal and paternal age using other variables and covariates. OUTCOMES AND RESULTS: The outcome was a developmental delay in the five domains of J-ASQ-3. In Model 3, ORs for the developmental delay scores regarding parental age were significantly associated with all five domains of J-ASQ-3. The mediation analysis showed a significant mediation interaction effect for mothers but localized for fathers. CONCLUSION: Advanced paternal and maternal ages were associated with developmental delay in children. Awareness of the risks of childbearing at an advanced age is crucial. WHAT'S THE PAPER ADDS: This manuscript used data from a large cohort study with multiple imputation and mediation analyses. With these analyses, we identified the pure effect of advanced parental age on their children's development at 36 months.

Early thrombus formation including hypo-attenuated leaflet thrombosis after surgical bioprosthetic aortic valve replacement.

OBJECTIVE: To assess the occurrence, predictors, and outcomes of hypo-attenuated leaflet thickening (HALT) and thrombus outside the prosthetic valve following surgical aortic valve replacement. METHODS: A total of 118 patients underwent surgical aortic valve replacement with bioprosthetic valves between July 2020 and June 2022. Sixty-two (52.5%) patients, which is a fairly high number of patients, underwent cardiac computed tomography and transthoracic echocardiography one week after surgery. Patients were divided into two groups, those with HALT (n = 14) and those without HALT (n = 48). RESULTS: Of the 62 patients who underwent cardiac computed tomography, HALT was observed in 14 (22.5%) patients during the very early postoperative phase. Reduced leaflet motion was observed in two of the 14 patients. The low-attenuation areas were located outside the prosthetic valve in 10 cases (71.4%) in the HALT group and in 14 cases (29.2%) in the non-HALT group. More than 50% of patients (57.1%) with HALT and 79.2% without HALT were administered warfarin. Neither in-hospital deaths nor postoperative thromboembolic events were observed during hospitalization. No patient had a mean pressure gradient > 20 mmHg in either group. CONCLUSION: HALT was observed in one-fifth of the cases after surgical aortic valve replacement during the very early postoperative phase in an institution wherein administration of continuous heparin infusion after surgery is a standard practice. HALT did not affect the early prognosis or incidence of cerebral infarction.

Preoperative management using Impella support for acute aortic dissection with left coronary malperfusion: a case report.

BACKGROUND: Acute aortic dissection (AAD) with impaired perfusion of the left coronary artery has a poor prognosis, even after urgent radical aortic surgery, due to extensive myocardial damage. Although Impella, a microaxial-flow catheter pump, is useful in managing acute myocardial infarction, it is generally contraindicated in patients with AAD because it is an intra-aortic device and the aortic structure is compromised in these cases. Here, we introduce a novel intervention that allowed a planned aortic repair after managing circulation using Impella and venoarterial extracorporeal membrane oxygenation in a case of AAD with left main trunk malperfusion. CASE PRESENTATION: A 40-year-old man presented with cardiogenic shock. Percutaneous coronary intervention was performed to address left main trunk obstruction using an intra-aortic balloon pump; however, circulatory instability persisted. The patient was transferred to our hospital after venoarterial extracorporeal membrane oxygenation. Impella CP™ was used to improve his circulatory status. However, a subsequent CT scan confirmed an AAD diagnosis. After 5 days of stable circulatory support, the patient underwent aortic root replacement and coronary artery bypass grafting. CONCLUSIONS: In patients with AAD and coronary malperfusion, adjunctive circulatory management with Impella may be a valuable therapeutic option.

A previously unreported case of suppurative thrombophlebitis due to Clavispora lusitaniae.

We report a case with Clavispora lusitaniae-induced purulent thrombophlebitis. The patient had multiple risk factors for the development of fungal thrombophlebitis including surgical procedure, mechanical ventilation, admission to intensive care unit, total parenteral nutrition and long-term antimicrobial therapy in addition to the insertion of central venous catheter. The symptoms finally improved by a combination therapy of micafungin and flucytosine, but the therapy did not rapidly resolve candidemia. The appropriate antifungal therapy for C. lusitaniae-induced purulent thrombophlebitis is uncertain. Further study is desired to seek the appropriate therapy for the disease.

A Case of Andexanet Alfa Induced Heparin Resistance in Emergent Aortic Surgery: Successful Anticoagulation Management Using Antithrombin Administration.

Andexanet alfa (AnAl) is utilized for the urgent reversal of direct oral anticoagulants (DOACs) in cases of severe bleeding. While the guidelines from the Society of Thoracic Surgeons recommend AnAl for urgent cardiac surgery in patients treated with DOACs, concerns persist regarding the potential of AnAl to induce heparin resistance. This report details the case of an 85-year-old woman diagnosed with acute type A aortic dissection, who received AnAl due to prior edoxaban use. During the emergent aortic surgery, she exhibited heparin resistance following the administration of unfractionated heparin (UFH). The administration of antithrombin III (ATIII) significantly influenced activated clotting times, facilitating successful surgery while maintaining adequate anticoagulation. This case underscores the importance of cautious management of AnAl-induced heparin resistance during critical surgeries, emphasizing the role of ATIII supplementation for effective anticoagulation.

Coronary artery bypass grafting via manubrium-sparing sternotomy in a patient with total laryngectomy and a permanent tracheostoma.

For patients who have previously undergone total laryngectomy and a permanent tracheostomy, median full sternotomy is not the ideal surgical approach because of the substantially increased risk of sternal wound complications and tracheal injuries. We present a case in which conventional coronary artery bypass grafting using bilateral internal thoracic arteries was performed safely via a manubrium-sparing sternotomy in a patient who had undergone total laryngectomy and a permanent tracheostoma. We also discuss the appropriate surgical approach for patients with total laryngectomy and a permanent tracheostoma.

Extracorporeal membrane oxygenation for the control of pulmonary artery hemorrhage.

We report a case of catheter-induced pulmonary hemorrhage, which had a favorable outcome on using extracorporeal membrane oxygenation. This procedure helped shunt pulmonary blood flow and significantly reduced bleeding from the pulmonary artery. Massive hemoptysis was observed while weaning the patient off cardiopulmonary bypass. Thus, catheter-induced pulmonary hemorrhage was suspected. After the bronchial blocker was inserted, extracorporeal membrane oxygenation was initiated to reduce pulmonary blood flow. The bronchial blocker was removed the day after the surgery, and the extracorporeal membrane oxygenation was withdrawn on the fourth day after the surgery. Tracheal bleeding did not recur during the postoperative period.

Short-segment coronary artery bypass grafting using radial artery to repair bilateral coronary ostial aneurysms after aortic root replacement in a patient with Marfan syndrome.

Coronary ostial aneurysm is a complication of aortic root replacement, particularly in Marfan syndrome. Reconstructing the coronary artery is an important problem during reoperation. Herein, we report a case of coronary artery bypass grafting using radial artery to repair bilateral coronary ostial aneurysms after aortic root replacement in a patient with Marfan syndrome.

Impact of the Trifecta bioprosthetic valve in patients with low-flow severe aortic stenosis.

Aortic stenosis (AS) is the most common valve disorder in advanced age. Previous reports have shown that low-flow status of the left ventricle is an independent predictor of cardiovascular mortality after surgery. The Trifecta bioprosthesis has recently shown favorable hemodynamic performance. This study aimed to evaluate the effect of the Trifecta bioprosthesis, which has a large effective orifice area, in patients with low-flow severe AS who have a poor prognosis. We retrospectively evaluated 94 consecutive patients with severe AS who underwent aortic valve replacement (AVR). Patients were divided into two groups according to the stroke volume index (SVI): low-flow (LF) group (SVI < 35 ml/m2, n = 22) and normal-flow (NF) group (SVI ≥ 35 ml/m2, n = 72). Patients' characteristics and early and mid-term results were compared between the two groups. There were no differences in patients' characteristics, except for systolic blood pressure (LF:NF = 120:138 mmHg, p < 0.01) and the rate of atrial fibrillation between the groups. A preoperative echocardiogram showed that the pressure gradient was higher in the NF group than in the LF group, but aortic valve area was similar. The Trifecta bioprosthesis size was similar in both groups. The operative outcomes were not different between the groups. Severe patient-prosthesis mismatch (PPM) (< 0.65 cm2/m2) was not observed in either of the groups. There were no significant differences in mid-term results between the two groups. The favorable hemodynamic performance of the Trifecta bioprosthesis appears to have the similar outcomes in the LF and NF groups. AVR with the Trifecta bioprosthesis should be considered for avoidance of PPM, particularly in AS patients with LV dysfunction.

Prevention of postoperative intrapericardial adhesion by dextrin hydrogel.

OBJECTIVE: Postoperative intrapericardial adhesion increases the risk of complications in patients undergoing reoperation. We investigated the effect of a bioabsorbable dextrin hydrogel (DHG) on the formation of intrapericardial adhesions. METHODS: Intrapericardial adhesion was surgically induced in Japanese white rabbits with DHG treatment (Adh + DHG) or without DHG treatment (Adh). The sham group was not treated with DHG and intrapericardial adhesion was not induced. The extent of intrapericardial adhesion was assessed by adhesion scoring and crystal violet staining of the pericardial cavity. Bromodeoxyuridine (BrdU) uptake assay was performed to assess the proliferative response to the injury in the tissue beneath the intrapericardial adhesion. RESULTS: The Adh + DHG group showed looser intrapericardial adhesions compared to the Adh group. The adhesion area of the Adh + DHG group was 4.6 ± 2.2%, whereas that of the Adh group was 32.6 ± 6.4% at the end of the 28-day observation period (p < 0.01). The induction of intrapericardial adhesion resulted in a proliferative response mainly in the cardiac tissue just beneath the adhesion. There were 48.6 ± 10.7 cells/0.1 mm2 BrdU-positive cells in the Adh + DHG group and 135.7 ± 23.8 cells/0.1 mm2 BrdU-positive cells in the Adh group on day 28 (p < 0.05). CONCLUSION: These findings indicate that DHG effectively prevented intrapericardial adhesion in this model.

Pathological Role of Receptor for Advanced Glycation End Products in Calcified Aortic Valve Stenosis.

Background Aortic stenosis (AS) is highly prevalent in patients with atherosclerotic cardiovascular disease. Advanced glycation end products (AGEs) and the receptor for AGEs (RAGE) play a pivotal role for vascular calcification in atherosclerosis. We hypothesize that the AGEs-RAGE axis could also be involved in the pathophysiological mechanism of calcified AS. Methods and Results A total of 54 patients with calcified AS who underwent aortic valve replacement were prospectively enrolled from 2014 to 2016 (mean age 75.3±7.7 years). Aortic valve specimens were obtained from 47 patients and 16 deceased control subjects without aortic valve disease (mean age 63.2±14.5 years). The valvular expression of RAGE was evaluated by immunohistochemistry. Serum levels of AGEs and soluble RAGE were measured in 50 patients with calcified AS and 70 age-matched and sex-matched control subjects without heart disease. The valvular RAGE expression in patients with calcified AS was higher than controls (P=0.004) and was significantly associated with a decreased ankle-brachial pressure index (P=0.007) and an increased intima-media thickness (P=0.026). RAGE and α-smooth muscle actin were coexpressed and were partially costained with osteocalcin and alkaline phosphatase. The serum levels of AGEs and soluble RAGE were significantly higher in the patients with calcified AS than in the controls (P=0.013 and P<0.001, respectively). Soluble RAGE (inversely) and use of aspirin were independently correlated with changes in left ventricular systolic function after aortic valve replacement (P=0.012 and P=0.002, respectively). Conclusions Our present study suggests that RAGE may play a role in the pathogenesis of calcified AS, which is a prognostic marker in patients with AS after aortic valve replacement.

Left ventricular apical pseudoaneurysm with aortic prosthetic valve endocarditis.

We report an 83-year-old man with a mycotic left ventricular apical pseudoaneurysm and aortic prosthetic valve endocarditis caused by Enterococcus spp. Mycotic left ventricular pseudoaneurysm is very rare and is associated with a high risk of rupture. Here, we report the clinical presentation, diagnosis, prognosis, and treatment of a case of mycotic left ventricular pseudoaneurysm to raise awareness regarding this unusual and potentially fatal complication.

Florida sleeve technique for a right sinus of Valsalva aneurysm: a case report.

BACKGROUND: Florida sleeve technique was reported by Hess et al. as a new technique of valve sparing aortic root replacement without the requirement of entire aortic root wall resection and coronary artery reconstruction. We present a rare case of an unruptured aneurysm of the right sinus of Valsalva that was successfully treated with resection of the aneurysm and the Florida sleeve technique. CASE PRESENTATION: A 72-year-old man was admitted for the treatment of an unruptured aneurysm of the right sinus of Valsalva. Computed tomography showed an aneurysm of the right sinus of Valsalva measuring > 40 mm and protruding into the right ventricular outflow tract. The aneurysm dilated up to 5 mm per year, and the left sinus of Valsalva and non-coronary sinus of Valsalva also showed dilation, and he underwent resection of only the right sinus of Valsalva aneurysm and valve sparing aortic root replacement with the Florida sleeve technique. CONCLUSIONS: We performed valve-sparing aortic root replacement with the Florida sleeve technique. It could reduce surgical risks and prevent a dilatation of the residual sinus of Valsalva through coverage with a graft for a long term.

A pediatric case with parvovirus B19-associated uveitis without autoantibody formation.

Acute parvovirus B19 (B19) infection is often accompanied by autoantibody formation, including antinuclear antibodies and rheumatoid factor, and the symptoms of the infection are similar to those of several autoimmune diseases. Uveitis is a representative manifestation of autoimmune diseases and is rarely caused by B19. Autoantibody formation was confirmed in 2 previously reported cases with B19-associated uveitis. However, whether B19-associated uveitis is caused by the direct invasion of the virus or the induction of autoimmunity remains unclear. We herein report a pediatric case with B19-associated uveitis without autoantibody formation. We speculated that B19 might have directly invaded the eye in this patient because of the development of uveitis without antibody formation and the negative results for anti-B19-specific antibodies in the serum at the onset of the disease. Although the mechanism of invasion is unknown, B19 may have a high affinity for tissue in the eye.

A recurrent homozygous NHLRC1 variant in siblings with Lafora disease.

We report a case of two siblings with progressive myoclonus epilepsy whose parents were not consanguineous. Their clinical symptoms were typical of Lafora disease (LD), but skin biopsies revealed no Lafora bodies. Whole-exome sequencing identified a recurrent homozygous frameshift variant in the NHLRC1 gene in both siblings. The genetic analysis was useful for the diagnosis of LD, as neither consanguinity nor Lafora bodies were found.

[ACTH therapy for two cases of epileptic spasms without hypsarrhythmia].

We present two patients with epileptic spasms without hypsarrhythmia (ESWoH) who were successfully treated with ACTH. One patient was an 18-month-old boy who had normal development for the first 16 months of his life. Thereafter, he experienced sudden flexion of the axial muscles, resulting in head nodings, or epileptic spasms (ES). EEG tracings showed generalized polyspikes that appeared frequently during sleep without associated hypsarrhythmia. We were thus able to diagnose him with ESWoH and treated him with ACTH, which resolved his seizures. Another patient was a 7-year-old boy. At 18 months of age, the patient began to sufferdil from sudden ES. Anti-epileptic drugs were administered individually and in combination but were proved ineffective. Like the first case, this child's EEG tracing showed generalized polyspikes during sleep without associated hypsarrhythmia. We diagnosed him with ESWoH and treated him with ACTH. His ES disappeared soon after the initiation of treatment. These two cases demonstrate the difficulty of treating ESWoH only with standard anti-epileptic drugs, we emphasize the importance of early treatment with ACTH.
