RESUMO
Purpose: This study addresses the critical issue of fertility preservation among young patients with cancer in Japan, recognizing the brief decision-making window and the need for comprehensive support. Pharmacists, well-versed in the side effects of anticancer drugs, can play a vital role in this support process. However, the extent of pharmacists' involvement in fertility preservation remains unclear. We aimed to investigate pharmacists' roles in addressing cancer treatment-induced fertility concerns and their collaboration with physicians, offering insights into enhancing pharmacist participation in fertility preservation. Methods: A survey conducted between April and July 2022 targeted doctors and pharmacists at cancer treatment hospitals, along with pharmacists affiliated with the Japanese Society of Pharmaceutical Health Care and Sciences. Results: Our findings indicated that although pharmacists had limited knowledge about gonadotoxicity and fertility, they expressed readiness to conduct research and provide information when consulted. Approximately 10%-20% of the pharmacists participated in explaining the primary disease at diagnosis. Pharmacists played a more prominent role after establishing chemotherapy regimens, with less involvement in its formulation. Notably, treatment decision case conferences emerged as crucial forums for gathering patient data, confirming treatment plans, and identifying those in need for fertility preservation information. Roughly half of the pharmacists attended these conferences, suggesting a need for increased participation. Conclusion: Enhancing physician-pharmacist collaboration could be pivotal for effective fertility preservation. This requires augmenting the knowledge and awareness of both professions and encouraging greater participation in case conferences to create a conducive environment for addressing this critical aspect of cancer care.

A 63-year-old man with a confirmed case of coronavirus disease 2019 and having complaints of severe pain and paralysis in his right lower limb was transported to our hospital in an ambulance. Because of thrombosis, a computed tomography angiogram revealed the occlusion of right common iliac artery and stenosis of abdominal aorta. Emergency angiography and thrombectomy were performed; after surgery, the patient was managed in the intensive care unit with mechanical ventilation and hemodialysis for renal failure. However, on postoperative day 7, thrombosis recurred, and he died because of multiple organ failure.
RESUMO
We previously reported the effectiveness of autologous mesenchymal stromal cells (MSCs) for the treatment of aortic aneurysm (AA), mediated mainly by these cells' anti-inflammatory properties. In this study, we investigate whether the therapeutic effects of allogeneic MSCs on AA are the same as those of autologous MSCs. To examine the immune response to allogeneic MSCs, C57BL/6 lymphocytes were co-cultured with BALB/c MSCs for 5 days in vitro. Apolipoprotein E-deficient C57BL/6 mice with AA induced by angiotensin II were randomly divided into three groups defined by the following intravenous injections: (i) 0.2 ml of saline (n = 10, group S) as a control, (ii) 1 × 106 autologous MSCs (isolated from C57BL/6, n = 10, group Au) and (iii) 1 × 106 allogeneic MSCs (isolated from BALB/c, n = 10, group Al). Two weeks after injection, aortic diameters were measured, along with enzymatic activities of MMP-2 and MMP-9 and cytokine concentrations in AAs. Neither allogenic (BALB/c) MSCs nor autologous (C57BL/6) MSCs accelerated the proliferation of lymphocytes obtained from C57BL/6. Compared with group S, groups Au and Al had significantly shorter aortic diameters (group S vs Au vs Al; 2.29 vs 1.40 vs 1.36 mm, respectively, p < 0.01), reduced MMP-2 and MMP-9 activities, downregulated IL-6 and MCP-1 and upregulated expression of IGF-1 and TIMP-2. There were no differences in these results between groups Au and Al. Thus, our study suggests that treatment with allogeneic MSCs improves chronic inflammation and reduced aortic dilatation. These effects were equivalent to those of autologous MSCs in established mouse models of AA.

BACKGROUND: Several studies have analyzed risk factors that may influence the incidence of type II endoleak with sac expansion after endovascular aneurysm repair (EVAR). However, the impact of intraluminal thrombus volume on the incidence of sac expansion with type II endoleak requires further analysis. This study examined the correlation between preoperative intraluminal thrombus and the incidence of type II endoleak and late sac expansion by measuring the thrombus volume. METHODS: Between June 2007 and March 2014, 423 patients underwent EVAR at our institution. Two hundred and eighty patients with preoperative and postoperative computed tomography angiography (CTA) were included in this study. Data were collected prospectively and supplemented with a retrospective review of the medical records and radiologic images, and demographic and clinical characteristic profiles were collected. Logistic regression and Cox regression analyses were used to assess each variable's association with the incidences of persistent or new endoleak and sac expansion. RESULTS: Of the 280 patients, 46.7% (131 patients) had persistent type II endoleak, and 19.6% (55 patients) had persistent type II endoleak with significant sac expansion (≥5 mm). The mean follow-up duration was 60 months (interquartile range, 24-72 months). Cox regression analysis showed that older age (P = 0.001), intraluminal thrombus volume ratio (thrombus volume [T vol]/aortic aneurysm volume [A vol]) (P = 0.042) and IMA diameter (P = 0.004) were significant predictors of the incidence of sac expansion with persistent or new type II endoleak. The receiver operating characteristic curve analysis revealed a cutoff of 51% T vol/A vol (area under the curve [AUC]: 0.59) and 2.9 mm (area under the curve [AUC]: 0.60). The rate of freedom from sac expansion (≥5 mm) during followup was significantly higher in patients with ≥51% T vol/A vol than in those with a lower T vol/A vol (P = 0.010). CONCLUSIONS: Preoperative sac thrombus volume, IMA diameter, and older age predict the incidence of aneurysm expansion with type II endoleak after EVAR.

BACKGROUND: Several reports have indicated that suprarenal (SR) fixation may impair renal function after endovascular abdominal aortic aneurysm repair (EVAR). However, most were short-term or at most, 1-year observational studies; therefore, the midterm effects on renal function remain unclear. This study aimed to identify predictors of midterm renal dysfunction after EVAR and compare renal outcomes in patients after EVAR with SR and infrarenal (IR) fixation. METHODS: A total of 467 patients who underwent EVAR of nonruptured IR abdominal aortic aneurysm between 2007 and 2014 were reviewed in a prospectively collected database. Patients on hemodialysis at baseline were excluded. Among the remaining patients, those with 3-year laboratory testing were included in this study. Patients who developed acute kidney injury were excluded from the late renal function estimation. Predictors of 3-year renal function decline were estimated using logistic regression analysis. In addition, patients undergoing EVAR with IR (IR group) and SR fixation devices (SR group) were propensity matched by age, sex, baseline renal function, baseline aneurysm diameter, comorbidities, smoking habits, and regular use of medicines that may act on kidney function. Changes in renal function after surgery were compared between the IR group and the SR group. RESULTS: During the study period, 237 patients (102 IRs and 135 SRs) were followed up with laboratory testing 3 years after surgery. Logistic regression analysis revealed that the use of a SR fixation device was independently predictive of a more than 20% decrease in the estimated glomerular filtration rate at 3 years after EVAR (odds ratio, 2.06; 95% confidence interval, 1.18-3.58; P = .011). Eleven patients who developed acute kidney injury (1 IR and 10 SRs) were excluded from the subsequent analysis. After propensity score matching, 87 pairs were selected (mean age, 77.2 ± 6.3 years; 151 males [86.8%]). The mean follow-up duration was 5.5 ± 1.8 years. In the SR group, estimated glomerular filtration rate at 3 years after surgery decreased significantly more than that in the IR group (mean of 17.8% vs 11.6%, respectively; P = .034). CONCLUSIONS: This study suggests that, compared with EVAR with IR endograft fixation, EVAR with SR endograft fixation is associated with worse outcomes for midterm renal function.

BACKGROUND: Prior studies have shown that a bird-beak configuration causes serious complications after thoracic endovascular aortic repair (TEVAR). However, factors that cause bird-beak configurations are poorly understood. The purpose of this study was to assess the influences of anatomical and device-related factors on bird-beak configuration. METHODS: Sixty-eight consecutive patients (47 men, mean age, 72.8 ± 9.8 years) who underwent TEVAR with proximal fixation in zones 1 to 3 from March 2009 to February 2017 were included. Preoperative and postoperative computed tomography (CT) scans were retrospectively reviewed. Relationships between the incidence of a bird-beak configuration, preoperative aortic arch morphology, and type of stent graft were estimated. The influence of a bird-beak configuration on endograft migration over time was also estimated for 47 patients who underwent CT 12 months after TEVAR. RESULTS: The patients' aortic arch pathologies included 52 aneurysms, 11 aortic dissections, 4 pseudoaneurysms, and 1 patent ductus arteriosus. Stent grafts with (the proximal bare stent group [PBS group]) and without (the nonbare stent group [NBS group]) a proximal bare stent were implanted in 24 and 44 patients, respectively. A bird-beak configuration was detected in 30 patients (mean length ± standard deviation [SD], 6.2 ± 3.4 mm; mean angle ± SD, 31.7 ± 14.7°) and was significantly more frequent in the NBS group (n = 29) than in the PBS group (n = 1) (P < 0.001). Proximal landing zone, aortic lengths, and aortic arch morphology, including the radius, tortuosity, and angulation of aortic arch curvature, were not associated with the bird-beak configuration. The migration distance after 1 year was significantly longer in patients with a bird-beak configuration (3.5 ± 6.1 mm) than in patients without a bird-beak configuration (0.5 ± 1.0 mm) (P = 0.015). CONCLUSION: This study demonstrated that in aortic arch TEVAR, the use of stent graft with a proximal bare stent may reduce bird-beak configuration, which is associated with distal migration of the stent graft during follow-up.

BACKGROUND: Acquired somatic mutations of JAK2 have been reported to play a pivotal role in the pathogenesis of BCR-ABL1-negative myeloproliferative neoplasm (MPN). However, the molecular characteristics of childhood MPN remain to be elucidated. PATIENT AND METHODS: We investigated a group of pediatric patients diagnosed either with essential thrombocythemia (ET; N = 9) or polycythemia vera (PV; N = 4) according to WHO criteria (median age = 10 years; range 1.5-15 years) in whom direct sequencing was performed for the existence of genetic alterations in JAK2, MPL, TET2, ASXL1, CBL, IDH1, and IDH2. More sensitive allele specific polymerase chain reaction was used for JAK2(V617F) genotyping. RESULTS: We found three patients harbor JAK2(V617F) mutation (2/9 ET and 1/4 PV). Bone marrow examination showed small and large megakaryocytes with dysplastic features in JAK2(V617F)-positive ET patients compared to those without JAK2(V617F). We identified a previously unrecognized missense mutation at codon 1230 in exon 12 of ASXL1 gene in ET and PV patients (1/9 ET and 1/4 PV). Otherwise, no genetic alterations could be detected in JAK2 exon 12, MPL, TET2, CBL, IDH1, and IDH2 in all ET and PV patients. CONCLUSION: Although JAK2 mutations in childhood ET and PV are not as frequent as reported in adult patients, JAK2 is the most frequently mutated gene in childhood MPN known so far. Owing to the presence of childhood MPN without any genetic alterations in JAK2, MPL, TET2, ASXL1, CBL, IDH1, and IDH2, new biological markers have to be found.
