However, some patients have recently faced an additional load to treat life-related comorbidities and non-AIDS defining malignancies. The problem is that these diseases start to occur in the 40s- or 50s-year-old generations and that means HIV-infected persons are suffering from pre-mature aging. AIDS no longer signifies death. However, we still have a lot to improve for their quality of life.Balloon pulmonary angioplasty (BPA) has improved the survival rate of patients with chronic thromboembolic pulmonary hypertension (CTEPH). The resolution of symptoms is one of the remaining goals of BPA. Frailty affects the outcome of cardiovascular diseases or treatments. The aim of this study is to assess the association between frailty and outcome of BPA. The resolution of symptoms is evaluated by the post-BPA World Health Organization functional class (WHO-FC). A total of 54 patients with CTEPH were divided into 2 groups by post-BPA WHO-FC (WHO-FC I group; n = 34 vs. WHO-FC ≥ II group; n = 20). Frailty was assessed by physicians using the clinical frailty scale (CFS) at the point of patient admission for their first BPA sessions. Compared to the WHO-FC ≥ II group, the WHO-FC I group was younger (65.6 ± 13.9 years vs. 74.3 ± 8.0 years) and had a lower CFS (3 [3, 4] vs. 4 [4, 6]) (median [25th, 75th percentiles]). The WHO-FC I achievement rates for each CFS score were CFS 3 82.8%; 4 53.8%; 5 25.0%; 6 33.3%; and 7 20.0%. Logistic regression analysis showed that CFS was an independent predictor of WHO-FC I achievement (odds ratio 0.50, p = 0.012), but pre-BPA hemodynamic parameters and age were not independent predictors. Whether WHO-FC I can be achieved is predicted by pre-BPA patient frailty but not by pre-BPA hemodynamic parameters and age.In Japan, healthcare takes a "patient-centeredness" approach to prioritize providing rational medicine for patients under the initiative of medical doctors. This approach to healthcare is based on the concept that patients should receive the correct diagnosis and optimal treatment. The present report aims to provide an overview of the specific characteristics of healthcare in Japan to healthcare management professionals in other countries. We introduce the systems within Japan's healthcare framework, particularly "medical team approach", "nutrition management", and "infection controls", as well as treatment results in Japan using objective data to inform medical doctors in management positions in other parts of the world. Collectively, these three healthcare systems comprise the "patient-centeredness" philosophy through which Japanese healthcare professionals perceive ideal patient care and act accordingly. These healthcare systems are unique to Japan and were developed in accordance with the specific framework of Japanese history, systems, and culture. This report presents the effects of "patient-centeredness" healthcare based on treatment results and performance data by making a quantitative and qualitative comparison with healthcare in Europe and the USA. Further objective evaluation revealed that Japan demonstrates positive treatment results that are comparable to those of Europe and the USA due to its "patient-centeredness" rational medical system and the availability of the "correct diagnosis and optimal treatment". These findings introduce Japan's "patient-centeredness" medical and healthcare system with a view of informing and guiding improvements in the healthcare quality of other countries and promoting future international collaborations.Coronavirus disease (COVID-19) causes myocardial injury by inducing a cytokine storm in severe cases. Studies have reported that myocardial injury persists for a prolonged period during COVID-19 recovery, and cardiac troponin is a useful indicator of myocardial injury. Etomoxir The interleukin-6 (IL-6) level is known to be associated with the morbidity and mortality of COVID-19, but this association has not been studied during recovery. The current study examined the association between IL-6 levels and myocardial damage during COVID-19 recovery. Four of 209 patients (1.9%) who recovered from COVID-19 had elevated IL-6 levels. All 4 patients tested positive for high-sensitivity troponin T, and 3 patients had subclinical left ventricular (LV) dysfunction according to echocardiography. Positivity for IL-6 during COVID-19 recovery suggests ongoing myocardial damage due to inflammation.
Among various causes of insomnia, stress is the most common and representative cause. Insomnia is also known to negatively affect the quality of life (QoL). The objective of this study was to explore the effect of stress on QoL and the mediating role of insomnia symptoms in the relationship between stress and QoL.
In this study, the mediating effect of insomnia symptoms on the relationship between stress and QoL was analyzed by enrolling 3,714 participants from the Ansung and Ansan cohorts of the Korea Association Resource project from 2001 to 2004. These cohort participants were asked about how much they felt stressed during their everyday life. Insomnia symptoms were evaluated by asking participants whether they had trouble sleeping such as difficulty in falling asleep, disrupted sleep, and early morning awakening due to the lack of a validated questionnaire for this cohort. QoL was evaluated using the World Health Organization QoL Scale Brief Version.
In total, stress was positively associated with insomnia symptoms, which in turn predicted QoL. The same result could be derived from subgroup analysis according to sex, and it was confirmed that insomnia symptoms acted as a mediating factor more significantly in female than in male.
In this study, insomnia symptoms were confirmed to act as a significant mediating factor between stress and QoL, suggesting that insomnia symptoms should be actively identified and controlled to alleviate the negative effect of stress on QoL in clinical practice.

Optimal control is a reliable framework to prepare such a state while avoiding undesirable excitations, and, when applied to the time-dependent Gross-Pitaevskii equation (GPE) model of BEC in multiple space dimensions, results in a large computational problem. We propose a control method based on first reducing the problem, using a Galerkin expansion, from a partial differential equation to a low-dimensional Hamiltonian ordinary differential equation system. We then apply a two-stage hybrid control strategy. At the first stage, we approximate the control using a second Galerkin-like method known as the chopped random basis to derive a finite-dimensional nonlinear programing problem, which we solve with a differential evolution algorithm. This search method then yields a candidate local minimum which we further refine using a variant of gradient descent. This hybrid strategy allows us to greatly reduce excitations both in the reduced model and the full GPE system.Enhanced diffusion is an emergent property of many experimental microswimmer systems that usually arises from a combination of ballistic motion with random reorientations. A subset of these systems, autophoretic droplet swimmers that move as a result of Marangoni stresses, have additionally been shown to respond to local, self-produced chemical gradients that can mediate self-avoidance or self-attraction. Via this mechanism, we present a mathematical model constructed to encode experimentally observed self-avoidant memory and numerically study the effect of this particular memory on the enhanced diffusion of such swimming droplets. To disentangle the enhanced diffusion due to the random reorientations from the enhanced diffusion due to the self-avoidant memory, we compare to the widely used active Brownian model. Paradoxically, we find that the enhanced diffusion is substantially suppressed by the self-avoidant memory relative to that predicted by only an equivalent reorientation persistence timescale in the active Brownian model. We attribute this to transient self-caging that we propose is novel for self-avoidant systems. Additionally, we further explore the model parameter space by computing emergent parameters that capture the velocity and reorientation persistence, thus finding a finite parameter domain in which enhanced diffusion is observable.We propose a one-dimensional diffusion equation (heat equation) for systems in which the diffusion constant (thermal diffusivity) varies alternately with a spatial period a. We solve the time evolution of the field (temperature) profile from a given initial distribution, by diagonalizing the Hamiltonian, i.e., the Laplacian with alternating diffusion constants, and expanding the temperature profile by its eigenstates. We show that there are basically phases with or without edge states. The edge states affect the heat conduction around heat baths. In particular, rapid heat transfer to heat baths would be observed in a short-time regime, which is estimated to be t less then 10^-2s for the a∼10^-3m system and t less then 1s for the a∼10^-2m system composed of two kinds of familiar metals such as titanium, zirconium, and aluminium, gold, etc. We also discuss the effective lattice model which simplifies the calculation of edge states up to high energy. It is suggested that these high-energy edge states also contribute to very rapid heat conduction in a very short-time regime.By employing the exact enumeration technique on the lattice model of a polymer, we study the migration of the polymer chain across an entropic trap in a quasiequilibrium condition and explore the effect of solvent gradient present in the entropic trap which acts both parallel and perpendicular to the direction of migration. The Fokker-Planck formalism utilizes the free energy landscape of a polymer chain across the channel in the presence of the entropic trap to calculate the migration time. It is revealed that the migration is fast when the solvent gradient acts along the migration axis (i.e., x axis) inside the channel in comparison to the channel having the entropic trap. We report here for the first time that the entropic trap makes the migration faster at a certain value of solvent gradient. We also study the effect of transverse solvent gradient (along the y axis) inside the trap and investigate the structural changes of the polymer during migration through the channel. We observe the nonmonotonic dependence of migration time on the solvent gradient.Although hard rigid rods (k-mers) defined on the square lattice have been widely studied in the literature, their entropy per site, s(k), in the full-packing limit is only known exactly for dimers (k=2) and numerically for trimers (k=3). Here, we investigate this entropy for rods with k≤7, by defining and solving them on Husimi lattices built with diagonal and regular square-lattice clusters of effective lateral size L, where L defines the level of approximation to the square lattice. Due to an L-parity effect, by increasing L we obtain two systematic sequences of values for the entropies s_L(k) for each type of cluster, whose extrapolations to L→∞ provide estimates of these entropies for the square lattice. For dimers, our estimates for s(2) differ from the exact result by only 0.03%, while that for s(3) differs from best available estimates by 3%. In this paper, we also obtain a new estimate for s(4). For larger k, we find that the extrapolated results from the Husimi tree calculations do not lie between the lower and upper bounds established in the literature for s(k).
