Role regarding Lithium Doping in P2-Na0.67Ni0.33Mn0.67O2 for Sodium-Ion Electric batteries.
Intrahepatic Bruton's tyrosine kinase is mainly expressed on Kupffer cells and sinusoidal endothelial cells, and the inflammasome is activated in Kupffer cells. Our study found that inhibition of Bruton's tyrosine kinase effectively attenuated liver I/R injury by suppressing activation of the NLRP3 inflammasome in Kupffer cells.
Inflammatory Bowel Disease (IBD) treatment may increase the risk of infections. Vaccines are part of the comprehensive IBD patient care. The aim of this study was to describe indications and adherence of immunizations in IBD and identify possible associated factors.

A cross-sectional, analytic study was conducted in patients from an IBD Program of a tertiary center in Chile, between April - June 2019. Patients were asked to answer a vaccine survey and information also was obtained from the National Immunization Registry. Descriptive and association statistic were used (χ
; p<0.05).

A total of 243 patients were included (148 ulcerative colitis (UC), 86 Crohn's disease (CD) and 9 non-classifiable IBD). Only six patients (2%) of IBD patients received a complete immunization schedule. The highest vaccine rates were against influenza (67%), hepatitis B virus (40%), 13-valent pneumococcal (34%) and 23-polysaccharide pneumococcal (16%). The influenza vaccine rate has significantly increased, reaching 67% in 2019. The survey showed that 23% of patients have not been immunized with any vaccine, mainly due to lack of time, lack of medical prescription and high cost.

In this cohort, although vaccination rates are higher than previously reported, adherence to IBD immunization program would be improved, being considered since diagnosis by the multidisciplinary team.

Dermatomyositis (DM) in an auto-immune inflammatory myopathy with skin lesions, and, occasionally, organ involvement. Herein, we report a case of DM during anti-MDA5antibody therapy associated with interstitial lung disease (ILD) and pneumocystosis.

A 64-year-old woman was hospitalized for impairment of her general health and skin lesions. Dermatological examination revealed classic signs of DM associated with hyperkeratotic papules on the palm creases. This led us to suspect DM with anti-MDA5antibodies, which was subsequently confirmed by immunologic tests. We also noted dysphonia, exertional dyspnea and proximal muscles weakness. Despite early corticosteroid therapy, combined later with azathioprine, the patient's dyspnoea worsened; one month later, sudden pulmonary decompensation resulted in her admission to intensive care. A chest scan showed evidence of ILD and infectious signs, and the bronchoalveolar lavage was positive for Pneumocystisjiroveci. Despite treatment of this opportunist infection with endations concerning prophylaxis are currently available.This historical surgical retrospection focuses on the temporal de-escalation axillary surgery, focusing on the unceasing efforts of researchers toward new challenges, as documented by extensive studies and trials. Axillary surgery has evolved, aiming to offer the best oncologic treatment and improve the quality of life of women. Axillary lymph-node dissection (ALND) has been replaced by sentinel lymph-node biopsy (SLNB) in women with early clinically node-negative breast cancer, providing adequate axillary nodal staging information with minimal morbidity, and becoming the standard of care in the management of breast cancer. However, this is only the beginning. Strategies in defining systemic and radiotherapeutic treatments have gradually been optimized, offering increasingly refined and targeted breast cancer treatment tools. In recent years, the paradigm of completion ALND after a positive SLNB has been questioned, and several studies have led to revolutionary changes in clinical practice. Moreover, the increasingly pivotal role played by neoadjuvant chemotherapy (NAC) has had a profound effect on the extent of axillary surgery, paving the way to a more finite "targeted" procedure in women with node-positive breast cancer who convert to negative nodes clinically after NAC. The utility of SLNB itself and its subsequent omission in women with negative nodes clinically and breast conservative surgery is also under scientific evaluation. The changes over time in the surgical approach to breast cancer have been numerous and significant. The novel emerging perspective characterized by recent advances in biology and genetics, in dedicated axillary ultrasound imaging and chemotherapy regimens, is the present reality that points to the future of axillary node treatment in breast cancer.Refinement of therapies continues to improve the prognosis and survival of cancer patients. However, women of reproductive age face a risk of premature ovarian failure due to the gonadotoxicity of aggressive oncological treatment, which may also be used to treat other nonmalignant disorders. Development of cryobiology and assisted reproduction has allowed fertility preservation, which is increasingly requested, and can also aid fertility in iatrogenic and noniatrogenic conditions. Established protocols including embryo and oocyte freezing are only performed for adult women; however, ovarian tissue cryopreservation is an approach that can also assist prepubertal girls. Medical fertility cryopreservation for females has been recently legalized in Saudi Arabia. However, prior to implementing the service in clinical practice in Saudi Arabia, guidelines on patient selection criteria and adequate staff training are essential. Moreover, worldwide registry data and the findings of long-term studies involving many patients on the safety of ovarian tissue freezing are required to conclusively establish medical fertility cryopreservation as a safe procedure. Progress can be achieved in oncofertility by improving and optimizing techniques that include immature oocyte growth and maturation and artificial ovary development.
Fontan takedown remains an option for the management of Fontan failure. We sought to evaluate early and late outcomes after Fontan takedown.

The Australia and New Zealand Fontan Registry was interrogated to identify all patients who had a Fontan takedown.

Over a 43-year study period (1975-2018), 36 of 1540 (2.3%) had a Fontan takedown. The median age at takedown was 5.1years (interquartile range [IQR], 3.7, 7.0). Nine (25%) patients had a takedown within 48hours, 6 (16%) between 2days and 3weeks, 14 (39%) between 3weeks and 6months, whereas 7 (19%) had a late takedown (>6months). Median interval to takedown was 26days (IQR, 1.5, 127.5). Sixteen (44%) patients died at a median of 57.5days (IQR, 21.8, 76.8). The greatest mortality occurred between 3weeks and 6months (<2days 1/9, 11%; 2days to 3weeks 2/6, 33%; 3weeks to 6months 11/14, 79%; >6months 2/7, 28%; P=.007). At median follow-up of 9.4years (IQR, 4.5, 15.3), 11 (31%) patients were alive with an intermediate circulation (10 in New York Heart Association class I/II). Five (14%) patients underwent a successful second Fontan. Freedom from death/transplant after Fontan takedown was 59%, 56%, and 52% at 1, 5, and 10years, respectively.

The incidence of Fontan takedown is low, but mortality is high. The majority of takedowns occurred within 6months. Mortality was lowest when takedown occurred <2days and highest between 3weeks and 6months. A second Fontan is possible in a small proportion of survivors.

Anaplastic lymphoma kinase (ALK) rearrangement is a representative lung cancer with driver mutation because of the efficacy of ALK-tyrosine kinase inhibitors. ALK-tyrosine kinase inhibitors are extensively used for ALK-rearranged lung cancer, whereas the therapeutic benefit of surgery remains unclear. Thus, we aimed to assess the clinical benefit of surgery in ALK-rearranged lung cancer and to elucidate the oncologic characteristics of ALK-rearranged lung cancer through surgically resected cases.

We retrospectively evaluated 1925 lung adenocarcinoma cases surgically resected between 1996 and 2017 at our institute. Moreover, 75 ALK-rearranged and 75 non-ALK-rearranged cases were extracted using propensity score matching. The survival rates, prognostic factors, and post-recurrence state were assessed.

Multivariable analysis revealed that ALK rearrangement was an independent prognostic factor for improved cancer-specific survival (hazard ratio, 0.2;95% confidence interval, 0.05-0.88; P=.033). In the matcheombination of local and systemic therapies may be important treatment strategies for ALK-rearranged lung adenocarcinoma even in the post-recurrence state.
To assess the benefit/risk ratio to perform a coronary angiography (CA) before surgery for infective endocarditis (IE).

We conducted a single-center prospective registry including 272 patients with acute IE intended for surgery and compared patients who underwent a preoperative CA (n=160) with those who did not (n=112). A meta-analysis of 3 observational studies was also conducted and included 551 patients 342 who underwent a CA and 209 who did not.

In our registry, combined bypass surgery (CABG) was performed in 17% of the patients with preoperative CA. At 2years, the rate of the primary composite end point (all-cause death, new systemic embolism, stroke, new hemodialysis) was similar in the CA (38%) and no-CA (37%) groups. In-hospital and 2-year individual end points were all similar between groups. learn more There were only 2 episodes of systemic embolism after CA and only one possibly related to a vegetation dislodgement. In the meta-analysis, combined CABG was performed in 18% of the patients with preoperative CA. All-cause death was similar in both groups odds ratio, 0.98 [0.62-1.53], P=.92. Only 5 cases of systemic embolism possibly related to a vegetation dislodgement were reported. New hemodialysis was numerically more frequent in the CA group odds ratio, 1.68 [0.79-3.58] (18% vs 14%, P=.18).

In daily practice, two-thirds of the patients with acute IE who required surgery have a preoperative CA leading to a combined CABG in 18% of the patients. Our results suggest that to perform a preoperative CA in this context is not associated with improved prognosis.

Coarctation of the aorta (CoA) is associated with decreased exercise capacity despite successful repair with no residual stenosis; however, the hemodynamic mechanism remains unknown. This study aims to correlate aortic arch geometry with exercise capacity in patients with successfully repaired CoA and explain hemodynamic changes using 3-dimensional-printed aorta models in a mock circulatory flow loop.

A retrospective chart review identified patients with CoA repair who had cardiac magnetic resonance imaging and an exercise stress test. Measurements included aorta diameters, arch height to diameter ratio, left ventricular function, and percent descending aorta (%DAo) flow. Each aorta was printed 3-dimensionally for the flow loop. Flow and pressure were measured at the ascending aorta (AAo) and DAo during simulated rest and exercise. Measurements were correlated with percent predicted peak oxygen consumption (VO
max).

Fifteen patients (mean age 26.8±8.6years) had a VO
max between 47% and 126% predicted (mean 92±20%) with normal left ventricular function.
