Abstract

We conducted measurements of $K^- + {^3{\rm He}} \to \pi \!Y \!N + N'$ reactions using a $1~{\rm GeV}/c$ $K^-$-beam, with the objective of understanding the broad decay width of $\bar{K} \!N \!N$ (approximately twice as broad as that of $\Lambda(1405)$ considered to be the $\bar{K} \!N$ quasi-bound state). We successfully reproduced distributions of the $\pi \! Y \! N$ invariant mass and momentum transfer for $\pi \! Y \! N$ using model fitting functions for $\bar{K} \!N \!N$ formation and quasi-free $\bar{K}$ absorption (${\rm QF}_{\bar{K}-{\rm abs}}$) processes. The model can describe the experimental data quite well, and four $\bar{K} \! N \! N \to \pi \! Y \! N $ cross-sections were obtained. The results indicate that mesonic decay is the dominant decay branch of $\bar{K} \! N \! N$. The results also suggest that $\Gamma_{\pi \Lambda N} \sim \Gamma_{\pi \Sigma N}$, which indicates that the $I_{\bar{K} \! N}=1$ absorption channel, in addition to the $I_{\bar{K} \! N}=0$ absorption channel, substantially contribute to the $\bar{K} \! N \! N$ decay, making the $\bar{K} \! N \! N$ state approximately twice as unstable as $\Lambda$(1405).

Abstract

We measured a set of $\pi^\pm\Sigma^\mp$, $\pi^0\Sigma^0$, and $\pi^-\Sigma^0$ invariant mass spectra below and above the $\bar{K}N$ mass threshold in $K^-$-induced reactions on deuteron. We deduced the $S$-wave $\bar{K}N\rightarrow\pi\Sigma$ and $\bar{K}N\rightarrow\bar{K}N$ scattering amplitudes in the isospin 0 channel in the framework of a $\bar{K}N$ and $\pi\Sigma$ coupled channel. We find that a resonance pole corresponding to $\Lambda(1405)$ is located at 1417.7$^{+6.0}_{-7.4}$(fitting errors)$^{+1.1}_{-1.0}$(systematic errors) + $[-26.1^{+6.0}_{-7.9}$(fitting errors)$^{+1.7}_{-2.0}$(systematic errors)]$i$ MeV/$c^2$, closer to the $\bar{K}N$ mass threshold than the value determined by the Particle Data Group., Comment: 8 pages, 5 figures

Abstract

$\bar K$-nuclear bound systems, kaonic nuclei, have been widely discussed as products of the strongly attractive $\bar K N$ interaction in $I = 0$ channels. Recently, we demonstrated that kaonic nuclei can be produced via in-flight $(K^-,N)$ reactions using the low-momentum DC kaon beam at the J-PARC E15 experiment. We observed the simplest kaonic nuclei, $K^-pp$, having a much deeper binding energy than normal nuclei. For further studies, we have proposed a series of experimental programs for the systematic investigation of light kaonic nuclei, from $\bar K N$ ($\Lambda(1405)$) to $\bar K NNNN$. In the new experiment approved as J-PARC E80, we will measure the $\bar K NNN$ ($A=3$) system as a first step toward a comprehensive study., Comment: 10 pages, 5 figures, proceedings of the 8th Asia-Pacific Conference on Few-Body Problems in Physics (APFB2020), accepted for publication in Fwe-Body Systems

Abstract

We have performed an exclusive measurement of the $K^{-}+\! ~^{3}{\rm He} \to \Lambda pn$ reaction at an incident kaon momentum of $1\ {\rm GeV}/c$.In the $\Lambda p$ invariant mass spectrum, a clear peak was observed below the mass threshold of $\bar{K}\!+\!N\!+\!N$, as a signal of the kaonic nuclear bound state, $\bar{K}NN$.The binding energy, decay width, and $S$-wave Gaussian reaction form-factor of this state were observed to be $B_{K} = 42\pm3({\rm stat.})^{+3}_{-4}({\rm syst.})\ {\rm MeV}$, $\Gamma_{K} = 100\pm7({\rm stat.})^{+19}_{-9}({\rm syst.})\ {\rm MeV}$, and $Q_{K} = 383\pm11({\rm stat.})^{+4}_{-1}({\rm syst.})\ {\rm MeV}/c$, respectively. The total production cross-section of $\bar{K}NN$, determined by its $\Lambda p$ decay mode, was $\sigma^{tot}_{K} \cdot BR_{\Lambda p} = 9.3\pm0.8({\rm stat.})^{+1.4}_{-1.0}({\rm syst.})\ \mu{\rm b}$.We estimated the branching ratio of the $\bar{K}NN$ state to the $\Lambda p$ and $\Sigma^{0}p$ decay modes as $BR_{\Lambda p}/BR_{\Sigma^{0}p} \sim 1.7$, by assuming that the physical processes leading to the $\Sigma N\!N$ final states are analogous to those of $\Lambda pn$., Comment: 13 pages, 12 figures

Abstract

We observed a distinct peak in the $\Lambda p$ invariant mass spectrum of $^{3}{\rm He}(K^-, \, \Lambda p)n$, well below the mass threshold of $m_K + 2 m_p$. By selecting a relatively large momentum-transfer region $q = 350 \sim 650$ MeV/$c$, one can clearly separate the peak from the quasi-free process, $\overline{K}N \rightarrow \overline{K}N$ followed by the non-resonant absorption by the two spectator-nucleons $\overline{K}NN \rightarrow \Lambda N $. We found that the simplest fit to the observed peak gives us a Breit-Wigner pole position at $B_{\rm {\it Kpp}} = 47 \pm 3 \, (stat.) \,^{+3}_{-6} \,(sys.)$ MeV having a width $\Gamma_{\rm {\it Kpp}} = 115 \pm 7 \, (stat.) \,^{+10}_{-9} \,(sys.)$ MeV, and the $S$-wave Gaussian reaction form-factor parameter $Q_{\rm {\it Kpp}} = 381 \pm 14 \, (stat.)\,^{+57}_{-0} \,(sys.)$ MeV/$c$, as a new form of the nuclear bound system with strangeness -- "$K^-pp$"., Comment: 17 pages, 4 figures

Author

Andou, M, Yanai, S, Kanno, K, Sawada, M, Ochi, Y, and Kurose, Y

Abstract

This presentation will show five kinds of adnexal surgery using vNOTES. Five cases of vNOTES will be shown to highlight surgical techniques in adnexal tumor cases. All operations were conducted in a general hospital in Japan. Patients were all placed in the lithotomy position. Cases presented suffered from tubal pregnancy, simple ovarian cyst, solid ovarian tumor, benign cystic teratoma, and huge ovarian cystic tumor. The first case underwent a salphingectomy combined with adhesiolysis. The second case underwent an adnexectomy with a peri-ovarian adhesiolysis. The third case underwent an adnexectomy for a solid ovarian tumor using a retrieval protection bag. The fourth case underwent an ovarian cystectomy with intracorporeal suturing for hemostasis. The fifth case had a huge cystic tumor which required the draining of the content by a double balloon catheter to minimize spillage of tumor content. No patients experienced conversion to laparotomy or laparoscopy. No case underwent blood transfusion. No patients recorded pain on the second post operative day. vNOTES offers the advantage of a scarless surgery. This presentation shows how V-NOTES can be applied to a variety of adnexal tumor cases effectively and safely. [ABSTRACT FROM AUTHOR]

Abstract

Sitagliptin has been suggested as a treatment option for older adults with type 2 diabetes (T2D). However, no randomized controlled trial has been performed to evaluate the efficacy and safety of sitagliptin treatment in older Japanese patients with T2D. The STREAM study was a multicenter, open-label, randomized controlled trial. T2D outpatients aged 65–80 years with moderately controlled glycemic levels (HbA1c 7.4–10.4%) under lifestyle interventions without or with oral anti-diabetic drugs excluding DPP4 inhibitors or GLP-1 receptor agonists were recruited (n = 176). The participants were randomized into sitagliptin group (n = 88) who received sitagliptin as an initial or an additive anti-diabetic drug and control group (n = 88) who did not. The treatment goal was HbA1c level < 7.4%. Efficacy and safety during 12-month treatment period were investigated. The mean (± SD) ages were 70.6 ± 3.9 and 71.9 ± 4.4 years old in sitagliptin and control groups, respectively. According to a mixed-effects model analysis, average changes from baseline over the treatment period in fasting plasma glucose (FPG), HbA1c, and glycated albumin (GA) were − 27.2 mg/dL, − 0.61%, and − 2.39%, respectively, in sitagliptin group, and 0.50 mg/dL, − 0.29%, and − 0.93%, respectively, in control group. The reductions in FPG, HbA1c, and GA were significantly greater in sitagliptin group (P < 0.0001, P < 0.01, and P < 0.0001, respectively). There were no differences in the incidence of adverse effects, except for cystatin C elevation and platelet count reduction in sitagliptin group. Sitagliptin treatment effectively improved the glycemic profile without any serious adverse effects in older T2D patients. Trial registration number: UMIN000010376. [ABSTRACT FROM AUTHOR]

23. 12153 How Can We Manage Difficult Endometriosis Robotically?

Author

Andou, M, Yanai, S, Kanno, K, Sawada, M, Ochi, Y, and Hoshiba, T

Abstract

Endometriosis surgery can be difficult to perform due to fibrosis and severe adhesion. To make this surgery safer, we introduced robotics. Case studies from our da Vinci Xi and SP surgery series will be shown. All operations were conducted in a general hospital in Japan. Patient positioning was the same irrespective of whether procedures were single port or multi-port. Patients were all placed in the lithotomy position. Four cases suffering from severe and extensive deep endometriosis will be shown to explain the specific techniques used in each of the cases. Surgeries using the da Vinci Xi system will be Xi hysterectomy, and Xi lower anterior resection. Surgeries using the da Vinci SP system will be SP lower anterior resection, and SP ureteroneocystostomy. No patients underwent blood transfusion, and the maximum operative time was 2hr 50mins. The post-operative courses of all patients were uneventful. Patients could ambulate and take a regular diet the day after surgery. Robotic surgery for difficult endometriosis cases is feasible. Both da Vinci Xi and SP robots can be employed on a case-by-case basis and offer safe dissection and a good cosmetic result for patients. [ABSTRACT FROM AUTHOR]

24. Three Types of Minimally Invasive Paraaortic Lymphadenectomy.

Author

Andou, M, Yanai, S, Kanno, K, Sawada, M, Hoshiba, T, and Kurose, Y

Abstract

Originally open para-aortic dissection is very invasive. To reduce patient morbidity, we introduced minimally invasive extraperitoneal techniques. Techniques for minimally invasive para-aortic lymphadenectomy will be shown. All operations were conducted in a general hospital in Japan. Patients were all placed in the lithotomy position. Patient positioning was the same irrespective of whether procedures were single port or multi-port. We began laparoscopic para-aortic dissection in 1998 and da Vinci XP surgery in 2018. The SP system was introduced in 2023. In totally, we have performed more then 900 para-aortic lymphadenectomy surgeries. Techniques for minimally invasive para-aortic lymphadenectomy using various approaches will be shown. The progression of techniques using surgical robots top maximize minimally invasiveness will be described, specifically focusing on how-to's in real surgical circumstances. No patients underwent blood transfusion, and the post-operative courses of all patients were uneventful. Patients could ambulate and take a regular diet the day after surgery. Robotic surgery for para-aortic lymphadenectomy is feasible and makes this once invasive surgery patient-friendly. Both laparoscopy and robotics offer safe dissection and a good cosmetic result for patients. [ABSTRACT FROM AUTHOR]

Abstract

We have performed an exclusive measurement of the $K^{-}+\! ~^{3}{\rm He} \to ��pn$ reaction at an incident kaon momentum of $1\ {\rm GeV}/c$.In the $��p$ invariant mass spectrum, a clear peak was observed below the mass threshold of $\bar{K}\!+\!N\!+\!N$, as a signal of the kaonic nuclear bound state, $\bar{K}NN$.The binding energy, decay width, and $S$-wave Gaussian reaction form-factor of this state were observed to be $B_{K} = 42\pm3({\rm stat.})^{+3}_{-4}({\rm syst.})\ {\rm MeV}$, $��_{K} = 100\pm7({\rm stat.})^{+19}_{-9}({\rm syst.})\ {\rm MeV}$, and $Q_{K} = 383\pm11({\rm stat.})^{+4}_{-1}({\rm syst.})\ {\rm MeV}/c$, respectively. The total production cross-section of $\bar{K}NN$, determined by its $��p$ decay mode, was $��^{tot}_{K} \cdot BR_{��p} = 9.3\pm0.8({\rm stat.})^{+1.4}_{-1.0}({\rm syst.})\ ��{\rm b}$.We estimated the branching ratio of the $\bar{K}NN$ state to the $��p$ and $��^{0}p$ decay modes as $BR_{��p}/BR_{��^{0}p} \sim 1.7$, by assuming that the physical processes leading to the $��N\!N$ final states are analogous to those of $��pn$., 13 pages, 12 figures
