Abstract
Background Interventions to improve medication adherence in chronic conditions have shown limited success or sustainability. Previous data revealed that phone calls to patients regarding adherence goal awareness resulted in significant improvement in proportion of days covered (PDC). Objectives The objective of this study was to explore specific pharmacist adherence interventions via phone in various practice settings. Methods A prospective, randomized controlled study was conducted with patients who belonged to university-associated health care settings [ambulatory care, chain store, small health plan, and federally qualified health center (FQHC)]. At each site, patients with at least one chronic medication and a calculated PDC < 0.80 were randomized into control (n=115) and intervention (n=126) groups. Control groups (C) received usual pharmacy communication while intervention groups (X) were specifically called by a pharmacist to be informed of PDC goals and their commitment to adherence. PDC values were calculated 3 to 12 months for both groups the time of intervention, then compared with each patient's respective baseline/pre-PDC. Results Data from a total of 241 patients were pooled to examine change in PDC. There was no significant difference between groups in baseline criteria or PDC. Comparing within groups, there were significant correlations between Pre- and Post-PDCs for the intervention group (X = 0.32 p < 0.05) alone. There were significant improvements from initial PDC to those calculated at the time of Post-intervention PDC within both groups, (C = 0.18 ± 0.28 p < 0.05) and (X = 0.16 ± 0.24, p < 0.05). Approximately 44% of all sampled patients reached their adherence goals (PDC ≥ 0.80) after 3–9 months. Conclusions Results suggested that patient adherence behavior may improve after any call made by pharmacy staff. This communication and attention from the pharmacy may be enough for patients to consider their medication-taking habits without the need for discussing specific goals and importance of adherence.

Abstract
What is known and objective Favipiravir is a promising treatment candidate for managing coronavirus disease 2019 (COVID‐19). Warfarin has many drug interactions, but no interactions with favipiravir have been reported. Case summary Our patient was taking warfarin for deep vein thrombosis. The international normalized ratio (INR) was stable (1.65 to 2.0); however, it increased to 4.63 after administering favipiravir. The patient had no other factors justifying this change. What is new and conclusion Favipiravir and warfarin might have previously unidentified drug interactions that elevated the INR. Therefore, INR must be closely monitored when they are concomitantly administered in COVID‐19 patients.

Abstract
The frozen elephant trunk (FET) procedure enables easier replacement of the entire aortic arch because it does not require reaching the distal part of the left subclavian artery (LSCA). However, it requires additional management for reconstruction of the LSCA, which is associated with bleeding events. However, the fenestrated FET technique confers a risk of endoleakage from the fenestration site. We report our unique novel technique in which the proximal side of the hybrid stent graft is cut into V-shape around the subclavian artery and sutured continuously around the orifice of the subclavian artery during aortic stump fixation.

Abstract
Uterine leiomyosarcoma is a malignant soft tissue tumor resembling uterine fibroma clinically and is difficult to diagnose preoperatively. Since metastatic cardiac tumors are very rare and asymptomatic, most cardiac metastases are detected at autopsy after death due to other diseases. A 49-year-old woman presented with menorrhagia and anemia, and a uterine tumor. Total hysterectomy was performed for the uterine tumor. Histopathological examination revealed the tumor to be a leiomyosarcoma. Postoperative computed tomography showed multiple lung metastases and a metastatic cardiac tumor. The cardiac tumor, which was located within and almost entirely occluded the right ventricle, was 49 × 26 mm. To prevent sudden death, cardiac tumorectomy was performed semi-emergently. Chemotherapy was initiated in the early postoperative period, and the patient currently maintains a complete response. Cases with lung and cardiac metastases rarely undergo surgical resection of metastatic tumors. However, emergent surgical resection of cardiac metastatic tumors should be considered to prevent sudden death.

Abstract
Acceleration of particles from the interaction of ultraintense laser pulses up to 5×10^{21} W cm^{-2} with thin foils is investigated experimentally. The electron beam parameters varied with decreasing spot size, not just laser intensity, resulting in reduced temperatures and divergence. In particular, the temperature saturated due to insufficient acceleration length in the tightly focused spot. These dependencies affected the sheath-accelerated protons, which showed poorer spot-size scaling than widely used scaling laws. It is therefore shown that maximizing laser intensity by using very small foci has reducing returns for some applications.

Abstract
AIMS To provide information on the time-dependent behaviour of microbe staining by fluorescent dyes in the order of seconds, which is important in terms of the recent rapid and online techniques for microbe measurements and/or environmental microbe analysis. METHODS AND RESULTS For combinations of yeast (Saccharomyces cerevisiae) and typical dyes, including DAPI (4',6-diamidino-2-phenylindole) and Auramine-O, a suspension of yeast cells in ultrapure water was injected into a dye solution in a micro cuvette placed inside a spectrofluorometer and the fluorescence intensity of the resulting solution was measured at 1 s intervals, starting immediately after the mixing and continued until the time for the maximum intensity using various concentrations of yeast and dyes. The relaxation time τ, which corresponds to ~63·2% of the maximum fluorescence intensity, was shown to decrease to below 1 s with increasing DAPI concentration, whereas it remained constant for 2-3 s with increasing Auramine-O concentration, for example at a yeast concentration of 100 µg ml-1 . CONCLUSIONS For the conditions of yeast >10 µg ml-1 , DAPI >1 µg ml-1 and Auramine-O >0·1 µg ml-1 , τ could be adjusted to below 5 s to achieve a rapid and stable staining. SIGNIFICANCE AND IMPACT OF THE STUDY Design and operating conditions for rapid and online measurements of microbes can be optimized.

Abstract
Increasing the laser energy absorption into energetic particle beams represents a longstanding quest in intense laser-plasma physics. During the interaction with matter, part of the laser energy is converted into relativistic electron beams, which are the origin of secondary sources of energetic ions, γ-rays and neutrons. Here we experimentally demonstrate that using multiple coherent laser beamlets spatially and temporally overlapped, thus producing an interference pattern in the laser focus, significantly improves the laser energy conversion efficiency into hot electrons, compared to one beam with the same energy and nominal intensity as the four beamlets combined. Two-dimensional particle-in-cell simulations support the experimental results, suggesting that beamlet interference pattern induces a periodical shaping of the critical density, ultimately playing a key-role in enhancing the laser-to-electron energy conversion efficiency. This method is rather insensitive to laser pulse contrast and duration, making this approach robust and suitable to many existing facilities. Enhanced coupling of laser energy to the target particles is a fundamental issue in laser-plasma interactions. Here the authors demonstrate increased photon absorption leading into higher laser to electron and proton energy transfer through the interference of multiple coherent beamlets.

Abstract
Aims The role of hemofiltration (HF) during cardiopulmonary bypass (CPB) in adult cardiac surgery is controversial. It may be beneficial during prolonged CPB in high-risk surgery. Accordingly, we sought to compare two groups of patients undergoing high-risk cardiac surgery with or without HF. Methods One hundred and eighteen patients who underwent complex cardiac surgical procedures during a 12-month period were divided into two groups. Group I (n=61) comprised patients who were treated with hemofiltration during CPB. Group II (n=57) were not filtered. Estimated risk of death, standard demographic, clinical and surgical features were obtained and predetermined outcomes were studied. Statistical comparisons were made. Results Age, procedure times and mortality rates were similar in both groups. The mean volume of fluid removed in group I was 3.4 L. The preoperative mean Parsonnet score was 24.8 in group I and 22.5 in group II (ns). Postoperative serum hemoglobin, hematocrit, platelet, and albumin levels were all significantly higher in group I patients (p = 0.0015) indicating hemoconcentration. Post-operative chest drainage showed a trend toward decreased post-operative bleeding in group I (p=0.065). Postoperative pleural effusions requiring chest tube drainage were significantly less in group I (9.8% vs. 29.8% 6; p = 0.0062). The incidence of lung infection was also decreased from 26.3% to 13.1% (p=0.05). Operative mortality was similar in both groups (11.4% in group I, 10.5% in group II, ns). Conclusion Hemofiltration during CPB attenuates postoperative anemia, thrombocytopenia and hypoalbuminemia, may reduce post-operative bleeding and appears to decrease post-operative pulmonary complications.

Abstract
OBJECTIVE We previously reported a unique technique called "less invasive quick replacement (LIQR)" for treating type A acute aortic dissection with moderate hypothermic arrest (28 °C). This study examines the modified LIQR using mild hypothermic arrest (30 °C) with partial retrograde cerebral perfusion (RCP). METHODS 187 patients were divided into 2 groups: group L consisted of 130 patients underwent LIQR without any cerebral perfusion; group M consisted of 57 patients who were treated with modified LIQR. In modified LIQR, circulatory arrest was commenced under the 30 °C for open distal aortic stamp fixation. RCP was used during final half anastomosis of the prosthesis and then rapid re-warming was initiated. RESULTS The incidence of additional valve or coronary surgeries was significantly higher in group M (28.1%) than in group L (9.2%). The average rectal temperature was significantly higher in group M (29.5 °C) than in group L (27.4 °C). The durations of brain ischemia (M 7.7 min; L 18.6 min), cardiopulmonary bypass (M 82.0 min; L 93.3 min), and overall operation (M 145.2 min; L 154.2 min) were significantly shorter in group M. The incidence of postoperative brain damage was 6 patients (4.6%) in group L, but none in group M. The hospital mortality rate was 3 patients in group L (2.3%). All group M patients were discharged from the hospital without any complications. CONCLUSION Modified LIQR is safe and effective. It makes the surgery much quicker and is a less invasive procedure. The surgical outcome was also favorable.

Abstract
A 79-year-old man underwent bifurcated graft replacement for abdominal aortic aneurysm, but the graft was totally occluded owing to an acute type B aortic dissection. We could not have access to the root for performing endovascular stenting for dissecting aneurysm. Furthermore, it was difficult to remove the aneurysm via a left thoracotomy because it was impossible to perfuse the lower body with blood from the femoral artery and also a left axillary arterial cannulation was unusable. Herein, we report a patient who was successfully treated with open surgical aortic stenting for an enlarged ulcer-like projection complicated by a type B aortic dissection.

Abstract
PURPOSE We investigated the effectiveness of active renin-angiotensin-aldosterone system (RAAS) control with human atrial natriuretic peptide (hANP) and an angiotensin II receptor blocker (ARB) in patients with chronic kidney disease (CKD) undergoing coronary artery bypass grafting (CABG). METHODS A total of 286 consecutive patients with CKD undergoing CABG were divided into three groups: Group C (n = 50) receiving placebo, the hANP group (n = 60) receiving hANP, and the active RAAS control therapy (ARC) group (n = 56) receiving hANP plus an ARB. Renal function, brain natriuretic peptide (BNP) and RAAS parameters were analyzed. RESULTS After 1 year, renal function parameters were better in the hANP and ARC groups compared with group C, and the dialysis rate was significantly lower (group C: 12%, hANP group: 1.7%, ARC group: 1.8%, p = 0.018) in the hANP and ARC groups. BNP levels were significantly lower in the hANP and ARC groups compared with group C (p = 0.001). There was also a significant difference of aldosterone among the groups (p = 0.023), as well as a significant difference between group C and the ARC group (p = 0.017). CONCLUSIONS The present study showed that active RAAS control preserved renal function in patients with CKD undergoing CABG. The improved early postoperative outcome with RAAS control may lead to long-term inhibition of cardiovascular events.

Abstract
PurposeTo evaluate whether the length of the inner segment ellipsoid (ISe) band can be used as a prognostic factor for disease course in retinitis pigmentosa (RP) patients with EYS mutations by observation over a period of 5 years.MethodsTwelve RP patients with EYS mutations were studied. The horizontal and vertical ISe length of the right eye was manually measured at five time points annually, using spectral domain optical coherence tomography. A regression line through the five points from baseline to the final measurement was drawn and the ratio of the length (%) at each point to the baseline length was calculated; the slope was defined as the rate of ISe shortening (%/year). The correlation between the rate of ISe shortening and age, visual acuity, and mean deviation (MD) value were evaluated. The intraclass correlation coefficient (ICC) for the measurements was calculated.ResultsThe mean rate of ISe shortening was -4.65±2.89% per year and the decline was statistically significant. The rate of shortening was significantly negatively correlated with the baseline length (P=0.046, r=0.58), but not with the baseline age, visual acuity, and MD value. The ICC (2, 1) was 0.999.ConclusionsISe of all RP patients with EYS mutations shortened during the 5 years of annual observation. The measurement of the length of ISe is a simple and convenient method with high repeatability, and the length is a sensitive prognostic factor for the rate of ISe shortening in RP patients with EYS mutations.

Abstract
We assessed the midterm outcomes of 2 types of open surgical repair for type B dissecting aortic aneurysm (BDA). During the last 4 years, 86 patients with BDA (mean age, 68.5 ± 9.8 years; range: 41-87 years) underwent open repair. The average duration between the dissection onset and surgery was 51.5 ± 31.3 months. If the BDA was of open type with patent false lumen or the aneurysm extended for a long segment, descending or thoracoabdominal aortic repair was performed with left thoracotomy. If the BDA was of the closed type with thrombosed false lumen and the aneurysm was located around the distal arch, open stent implantation was performed with our unique technique using circulatory arrest with a rectal temperature of 28 °C without any cerebral perfusion. Left thoracotomy was performed in 68 patients. The durations of aortic clamping and cardiopulmonary bypass were 65.2 ± 16.9 and 78.5 ± 34.6 minutes, respectively. Open stent implantation was performed in 18 patients. The durations of circulatory arrest and cardiopulmonary bypass were 19.1 ± 5.1 and 86.2 ± 17.8 minutes, respectively. In the present study, 4 patients (4.7%) required reexploration for bleeding and 1 patient (1.2%) had a stroke, but none suffered paraplegia. The hospital mortality rate was 1.2% (1 patient), resulting from retrograde type A dissection. The actuarial aortic event-free survival rate, including operative death, was 96.4% at 3 years. Both open surgical procedures for BDA were relatively safe, with favorable early and midterm outcomes, and may be superior for avoiding neurologic complications.

Abstract
We use one- and two-dimensional particle-in-cell simulations to demonstrate that the propagation of an ultraintense laser (I=10(19)W/cm(2)) in critical density plasma can be interfered with by a high density plasma wall region generated at the propagation front. When the electron flow speed of the wall region exceeds a certain relativistic threshold, the region behaves as an overdense plasma due to a decrease of the effective critical density. The region forms then very small overdense plasma islands. The islands impede the propagation intermittently and slow down the propagation speed significantly.

Abstract
A new device of aortic stent graft made in Japan has been available since July 2014. Here, we describe a novel, unique surgical technique named "less invasive quick open stenting" at a rectal temperature of 28°C without any cerebral perfusion for treating distal arch aneurysms. All 12 patients were discharged from the intensive care unit within 24 hours after surgery without any complications. This technique aids in the exclusion of atherosclerotic plaques on the aortic wall and shortens the duration of circulatory arrest; moreover, it represents a very attractive option to prevent recurrent nerve injury.

Abstract
OBJECTIVES The US Food and Drug Administration has suggested that proton pump inhibitors (PPIs) increase the international normalized ratio (INR) when used concomitantly with warfarin (WF) because of being metabolized by cytochrome P450 2C19 (CYP2C19). We assessed whether CYP2C19 genotypes and type of PPI accentuated the drug interaction. METHODS AND RESULTS The study group was 82 patients who needed WF after surgery and had their CYP2C19 genotypes analyzed in advance. We randomly divided them into two groups: group I (n = 41) included patients who had lansoprazole 15 mg/day and group II (n = 41) included patients who had rabeprazole 10 mg/day. The dose of WF was controlled by the doctor in charge as a target INR of 1.6 to 2.6 during the 2 months after surgery. The maximum INR was significantly higher in group I (3.36 ± 0.98) than in group II (2.29 ± 0.55, p < 0.0001). The incidence of over-INR (> 3.5) was significantly higher in group I (15 cases) than in group II (2 cases, p = 0.0001). Several bleeding events complicated 10 patients in group I, but none in group II (p = 0.015). Logistic regression analysis revealed that over-INR (odds ratio [OR] 3.58, 95% confidence interval [CI]: 3.48-368.25, p < 0.0001), and pair of lansoprazole and CYP2C19 intermediate metabolizer (OR 2.39, 95% CI: 1.108-29.491, p = 0.0009) were independent predictors of bleeding events. CONCLUSION If a patient has had the intermediate metabolizer CYP2C19 genotype and concomitant use of WF and a PPI after open heart surgery, lansoprazole intensifies the effects of WF and is associated with bleeding events.

Abstract
AIM This subanalysis aimed to clarify whether intensive lipid-lowering therapy with statins slows the progression of atherosclerosis in Japanese subjects under treatment for primary prevention of cardiovascular disease. METHODS This was a subanalysis of the Justification for Atherosclerosis Regression Treatment (JART) Study. We compared the efficacy of intensive lipid-lowering therapy and conventional therapy with respect to changes in the mean intima-media thickness (IMT) and serum lipid levels. We also evaluated changes in the mean IMT over 24 months of treatment and assessed the relationship between these changes and reductions in the LDL-C levels using a post-hoc analysis. RESULTS Intensive lipid-lowering therapy with rosuvastatin was associated with significantly smaller changes in the mean IMT and a greater reduction in the serum lipid levels in comparison to conventional therapy with pravastatin. The average net change in the mean IMT was 0.010 mm (n=121) at 12 months and -0.004 mm (n=56) at 24 months. A decrease in LDL-C was found to be associated with a smaller change in the mean IMT (p=0.0009; Jonckheere-Terpstra trend test). A greater reduction in serum LDL-C was found to be associated with a smaller change in the mean IMT. Similar associations were observed for the serum TC and non-HDL-C levels and LDL-C/HDL-C ratio. There were no notable differences in the incidence of serious adverse events among the LDL-C quartiles. CONCLUSIONS Lowering the LDL-C level with intensive lipid-lowering therapy is associated with reduced changes in the IMT among Japanese subjects at moderate to high risk under treatment for primary prevention. Subjects suitable for primary prevention may receive cardiovascular benefits from intensive lipid-lowering therapy, in association with significantly slower IMT progression than that observed with conventional therapy.

Abstract
PURPOSE The aim of this study was to review the efficacy and toxicity of radiation therapy with concurrent retrograde superselective intra-arterial chemotherapy in the treatment of gingival carcinoma. METHODS AND MATERIALS In all, 34 patients (21 men and 13 women) with squamous cell carcinoma of the gingiva underwent radiation therapy with concurrent retrograde superselective intra-arterial chemotherapy. Treatment consisted of daily external irradiation and concurrent retrograde superselective intra-arterial infusion with cisplatin and docetaxel. A median total dose of 60 Gy in 30 fractions was delivered to tumors. RESULTS Of the 34 patients, 29 (85 %) achieved a complete response (CR) and 5 had residual tumors. Of the 29 patients with a CR, 2 had local recurrences and 1 had distant metastasis 1-15 months after treatment. Twenty-six of the 36 patients had survived at a median follow-up time of 36 months (range 12-79 months); 4 died of cancer and 4 died of non-cancer-related causes. At both 3 and 5 years after treatment, the overall survival rates were 79 % and the cause-specific survival rates were 85 %. Osteoradionecrosis of the mandibular bone only developed in 1 patient after treatment. CONCLUSION Radiation therapy with concurrent retrograde superselective intra-arterial chemotherapy was effective and safe in the treatment of gingival carcinoma. This treatment may be a promising curative and organ-preserving treatment option for gingival carcinoma.

Abstract
A 64-year-old man underwent a descending aortic replacement for a chronic type B dissecting aneurysm with left thoracotomy. The patient was weaned from the mechanical ventilator immediately after surgery without any neurological complications. However, on the second post-operative day, he suddenly suffered from cardiopulmonary arrest when talking with his family. Despite 6 hours of cardiopulmonary resuscitation, the patient died. The postmortem examination revealed a 1000 mL blood volume and huge hematoma in the pericardium owing to a retrograde type A dissection, which descended from an intimal laceration between the common carotid and left subclavian arteries that corresponded with aortic cross clamping. We here report a rare case of iatrogenic retrograde type A dissection caused by surgical clamping on the aortic arch 2 days post-surgery.

Abstract
BACKGROUND Febuxostat has been reported to have a stronger effect on hyperuricemia than allopurinol. METHODS AND RESULTS Cardiac surgery patients with hyperuricemia (n=141) were randomized to a febuxostat group or an allopurinol group. The study was single-blind, so the treatment was not known by the investigators. The primary endpoint was serum uric acid (UA) level. Secondary endpoints included serum creatinine, urinary albumin, cystatin-C, oxidized low-density lipoprotein (LDL), eicosapentaenoic acid/arachidonic acid ratio, total cholesterol, triglycerides, LDL, high-density lipoprotein, high-sensitivity C-reactive protein, blood pressure, heart rate, pulse wave velocity (PWV), ejection fraction, left ventricular mass index (LVMI), and adverse reactions. UA level was significantly lower in the febuxostat group than the allopurinol group from 1 month of treatment onward. Serum creatinine, urinary albumin, cystatin-C and oxidized LDL were also significantly lower in the febuxostat group. There were no significant changes in systolic blood pressure, PWV, and LVMI in the allopurinol group, but these parameters all had a significant decrease in the febuxostat group. CONCLUSIONS Febuxostat was effective for high-risk cardiac surgery patients with hyperuricemia because it reduced UA more markedly than allopurinol. Febuxostat also had a renoprotective effect, inhibited oxidative stress, showed anti-atherogenic activity, reduced blood pressure, and decreased PWV and LVMI.
