Patients with a diagnosis of HER2 positive early invasive breast cancer (cT1-3N0-1M0), from January 2012 to December 2014 were identified and enrolled continuously. The conditions of HER2-positive expression of primary breast cancer were defined as follows: HER2 3+ by immunohistochemical (IHC) method or HER2 2+ by IHC with a further positive result by fluorescence in situ hybridization (FISH). According to the real upfront treatment, all eligible patients were classified as PST group and surgery group. All the patients accepted standard one-year trastuzumab as anti-HER2 treatment combined with chemotherapy. In the PST group, the effect was evaluated according to RECIST1.1 every two cycles, the patients with clinical complete response (cCR) or partial response (PR) would receive the whole course of chemotherapy, those with stable disease (SD) or progressive disease (PD) would receive surgery promptly. After surgery, all patients underwent irradiation and endocrine therapies if necessary. The pCR was defined as the absence of infiltrating residual invasive disease in the breast and axillary nodes. For those non-pCR patients after PST, intensive adjuvant chemotherapy was not routine treatment except patients with progressive disease.The primary endpoint was DFS defined as the time from enrollment to local, regional, or distant recurrences; the occurrence of contralateral breast cancer; or death without evidence of breast cancer. Patients suffered disease progress becoming inoperable before surgery were counted as local treatment failures. The second endpoint was OS defined as the time from study entry to death from any cause. All the endpoints were compared between PST group and upfront surgery group, also further analysis according to pathological response status stratified in PST group.
The quest for scarless wound healing is imperative in healthcare, aiming to diminish the challenges of conventional wound treatment. Hyaluronic acid (HA), a key component of the skin's extracellular matrix, plays a pivotal role in wound healing and skin rejuvenation. Leveraging the advantages of HA hydrogels, this research focuses first on tuning the physicochemical and mechanical properties of photo-crosslinkable methacrylated HA (MAHA) by varying the methacrylation degree, polymer concentration, photo-crosslinker concentration, and UV exposure time. The optimized hydrogel, featuring suitable porosity, swelling ratio, degradability, and mechanical properties, was then used for the combined delivery of tannic acid (TA), known for its hemostatic, antibacterial, and antioxidant properties, and Wharton's jelly-derived mesenchymal stem cells (WJ-MSCs) cultured on the MAHA-TA hydrogel to enhance skin regeneration. The composite MAHA-TA-MSC hydrogel demonstrated favorable pores and biocompatibility, evidenced by cell viability, and promoted cell proliferation. When applied to dorsal wounds in rats, this composite hydrogel accelerated wound healing and reduced scarring. Additionally, molecular and histopathological analyses revealed increased expression of IL-10, the TGF-β3/TGF-β1 ratio, and the Collagen III/Collagen I ratio. These findings suggest that the MAHA-TA-MSC hydrogel is a promising candidate for scarless acute wound healing.
Posthemorrhagic shock mesenteric lymph (PHSML) return-contributed excessive autophagy of vascular smooth muscle cells (VSMCs) is involved in vascular hyporeactivity, which is inhibited by stellate ganglion block (SGB) treatment. The contractile phenotype of VSMCs transforms into a synthetic phenotype after stimulation with excessive autophagy. Therefore, we hypothesized that SGB ameliorates PHSML-induced vascular hyporeactivity by inhibiting autophagy-mediated phenotypic transformation of VSMCs. To substantiate this hypothesis, a hemorrhagic shock model in conscious rats was used to observe the effects of SGB intervention or intravenous infusion of the autophagy inhibitor 3-methyladenine (3-MA) on intestinal blood flow and the expression of autophagy- and phenotype-defining proteins in mesenteric secondary artery tissues. We also investigated the effects of intraperitoneal administration of PHSML intravenous infusion and the autophagy agonist rapamycin (RAPA) on the beneficial effect of SGB. The results showed that hemorrhagic shock decreased intestinal blood flow and enhanced the expression of LC3 II/I, Beclin 1, and matrix metalloproteinase 2, which were reversed by SGB or 3-MA treatment. In contrast, RAPA and PHSML administration abolished the beneficial effects of SGB. Furthermore, the effects of PHSML or PHSML obtained from rats treated with SGB (PHSML-SGB) on cellular contractility, autophagy, and VSMC phenotype were explored. Meanwhile, the effects of 3-MA on PHSML and RAPA on PHSML-SGB were observed. The results showed that PHSML, but not PHSML-SGB, incubation decreased VSMC contractility and induced autophagy activation and phenotype transformation. Importantly, 3-MA administration reversed the adverse effects of PHSML, and RAPA treatment attenuated the effects of PHSML-SGB incubation on VSMCs. Taken together, the protective effect of SGB on vascular reactivity is achieved by inhibiting excessive autophagy-mediated phenotypic transformation of VSMCs to maintain their contractile phenotype.
BACKGROUND: Approximately 2500 pediatric patients are awaiting kidney transplantation in the United States, with <5% comprising those ≤15 kg. Transplant in this cohort is often delayed by center-based growth parameters, often necessitating transplantation after the initiation of dialysis. Furthermore, prognostication remains somewhat ambiguous. In this report, we scrutinize the Organ Procurement and Transplantation Network (OPTN) data from 2001 to 2021 to help better understand specific variables impacting graft and patient outcomes in these children.
METHODS: The OPTN kidney transplant dataset from 2001 to 2021 was analyzed. Inclusion criteria included age <18 years, weight ≤15 kg, and recipient of primary living donor kidney transplantation (LDKT) or deceased donor kidney transplantation (DDKT). Patient and graft survival probabilities were calculated using the Kaplan-Meier method. The Cox proportional hazards model was used to calculate hazard ratio (HR) and identify variables significantly associated with patient and graft survival.
RESULTS: Two thousand one hundred sixty-eight pediatric transplant recipients met inclusion criteria. Patient survival at 1 and 3 years was 98% and 97%, respectively. Graft survival at 1 and 3 years was 95% and 92%, respectively. Dialysis was the sole significant variable impacting both patient and graft survival. Graft survival was further impacted by transplant era, recipient gender and ethnicity, and donor type. Infants transplanted at Age 1 had better graft survival compared with older children, and nephrotic syndrome was likewise associated with a better prognosis.
CONCLUSION: Pediatric kidney transplantation is highly successful. The balance between preemptive transplantation, medical optimization, and satisfactory technical parameters seems to suggest a "Goldilocks zone" for many children, favoring transplantation between 1 and 2 years of age.
Liver metastasis remains the primary cause of mortality in patients with colon cancer. Identifying specific driver gene mutations that contribute to metastasis may offer viable therapeutic targets. To explore clonal evolution and genetic heterogeneity within the metastasis, we conducted single-cell exome sequencing on 150 single cells isolated from the primary tumor, liver metastasis, and lymphatic metastasis from a stage IV colon cancer patient. The genetic landscape of the tumor samples revealed that both lymphatic and liver metastases originated from the same region of the primary tumor. Notably, the liver metastasis was derived directly from the primary tumor, bypassing the lymph nodes. Comparative analysis of the sequencing data for individual cell pairs within different tumors demonstrated that the genetic heterogeneity of both liver and lymphatic metastases was also greater than that of the primary tumor. This finding indicates that liver and lymphatic metastases arose from clusters of circulating tumor cell (CTC) of a polyclonal origin, rather than from a single cell from the primary tumor. Single-cell transcriptome analysis suggested that higher EMT score and CNV scores were associated with more polyclonal metastasis. Additionally, a mutation in the TRPS1 (Transcriptional repressor GATA binding 1) gene, TRPS1 R544Q, was enriched in the single cells from the liver metastasis. The mutation significantly increased CRC invasion and migration both in vitro and in vivo through the TRPS1R544Q/ZEB1 axis. Further TRPS1 mutations were detected in additional colon cancer cases, correlating with advanced-stage disease and inferior prognosis. These results reveal polyclonal seeding and TRPS1 mutation as potential mechanisms driving the development of liver metastases in colon cancer.
BACKGROUND: De-novo chronic neuropathic pain following COVID-19 is widely recognised. However, there are currently no published studies investigating the effect of SARS-CoV-2 infection on patients with pre-existing neuropathic pain who have required spinal cord stimulator (SCS) implantation. Here, the authors aimed to analyse outcomes in their institution's patients who had spinal cord stimulator (SCS) implantation or revision procedures to the system over a 5-year period. Specifically, the short-term and long-term outcomes of patients who contracted COVID-19 during the follow-up period were compared to the control group of patients who did not.
METHOD: Patients included in this study had spinal cord stimulator implantation (de-novo and revision procedures) between 1 January 2017 and 31 January 2022, for neuropathic pain of any aetiology. Patients deemed eligible for the study were invited to participate in a telephone survey through which clinical outcome data were collected. Pain scores were assessed with a modified form of the Brief Pain Inventory (BPI).
RESULTS: Of 91 patients, 48 (52.7%) had contracted COVID-19 by the time of the survey. Patients who contracted COVID-19 had significantly worse BPI scores in the 'Least pain' domain following their infection and at time of the survey, when compared to their score 6 months after the operation. 22.9% (n = 11) of the patients who contracted COVID-19 experienced a change in their symptoms following their infection. Within this sub-group, there was a statistically significant deterioration in BPI scores in 10/11 domains following their infection and in 2/11 domains at time of the survey. Worsening severity of COVID-19 symptoms was not associated with worse BPI scores.
CONCLUSIONS: Infection with SARS-CoV-2, in a significant proportion of patients with an SCS in situ, causes at least a transient deterioration in pain control. Further prospective multicentre studies are indicated to establish the prevalence of this phenomenon.

INTRODUCTION: Despite the decrease of hepatitis C in Spanish prisons in the last years, it still remains a reservoir for infection. The aim of this work is to analyze the characteristics of these patients and the response to antiviral treatment over the last 18 years.
METHODS: Retrospective observational study in inmates of Araba penitentiary center diagnosed with HCV infection between 2002 and 2020. A descriptive analysis of patient characteristics and the response to the three antiviral treatment modalities was performed: peg-interferon and ribavirin, peg-interferon, ribavirin and a first-generation protease inhibitor and different combinations of direct-acting antivirals.
RESULTS: A total of 248 antiviral treatments were prescribed. Treatment response rate up to 2015 was 65% and 93,7% after that year. Interferon non-responders were the main cause of non-response to treatment in periods 1 and 2 (40%-50%). Conversely, in period 3 viral breakthrough (67%) was the main culprit.
CONCLUSION: After 18 years, active hepatitis C infection in prison inmates has resolved with treatment according to clinical criteria. Therefore, the stay in prison may represent an opportunity to reduce the reservoir of the disease in the community, together with continued health care for those released from prison.
Subjects will apply the investigational product twice daily for 4 consecutive weeks. Subjects will be followed for 12 weeks post final application for a total of approximately 16 weeks of required participation in the study.
General Considerations

Ramipril capsules can cause symptomatic hypotension, after either the initial dose or a later dose when the dosage has been increased. Like other ACE inhibitors, ramipril capsules, have been only rarely associated with hypotension in uncomplicated hypertensive patients. Symptomatic hypotension is most likely to occur in patients who have been volume-and/or salt-depleted as a result of prolonged diuretic therapy, dietary salt restriction, dialysis, diarrhea, or vomiting. Correct volume-and salt-depletion before initiating therapy with ramipril capsules.

If excessive hypotension occurs, place the patient in a supine position and, if necessary, treat with intravenous infusion of physiological saline. Ramipril capsules treatment usually can be continued following restoration of blood pressure and volume.

Surgery and Anesthesia

In patients undergoing surgery or during anesthesia with agents that produce hypotension, ramipril may block angiotensin II formation that would otherwise occur secondary to compensatory renin release. Hypotension that occurs as a result of this mechanism can be corrected by volume expansion.

### General

Patients who are on corticosteroids are more susceptible to infections than are healthy individuals. There may be decreased resistance and inability to localize infection when corticosteroids are used. Infections with any pathogen (viral, bacterial, fungal, protozoan, or helminthic) in any location of the body may be associated with the use of corticosteroids alone or in combination with other immunosuppressive agents.

These infections may be mild, but can be severe and at times fatal. With increasing doses of corticosteroids, the rate of occurrence of infectious complications increases. Corticosteroids may also mask some signs of current infection. Do not use intra-articularly, intrabursally or for intratendinous administration for local effect in the presence of acute local infection.

A study has failed to establish the efficacy of Methylprednisolone Sodium Succinate in the treatment of sepsis syndrome and septic shock. The study also suggests that treatment of these conditions with Methylprednisolone Sodium Succinate may increase the risk of mortality in certain patients (i.e., patients with elevated serum creatinine levels or patients who develop secondary infections after Methylprednisolone Sodium Succinate).
Healthy subjects will be screened and different doses of X842 will be administered in multiple doses to assess the safety, tolerability, PK and PD profile of X842. The dose ascending at this stage will be based on the results of the single dose tolerability study.

Patients will be invited by mail to be screened for enrollment in the study. Interested patients will be able to complete an electronic consent form and enroll online via Research Electronic Data Capture (REDCap) version 5.0.8. Study participants will complete questionnaires electronically via email using REDCap at two time points: baseline (T0) and one-month follow-up (T1). Participants will complete a baseline questionnaire (T0) including basic demographic questions, items about computer usage and internet access, and validated measures of health literacy and eHealth literacy. Each participant will have access to MDC for 1 month.
BACKGROUND: Mobility limitation, a manifestation of impaired intrinsic capacity, is the first obvious sign of functional decline. However, few studies have been conducted on the prevalence and incidence of mobility limitation. This study aimed to estimate the prevalence and incidence of mobility limitation in Chinese older adults (over 60 years old) and evaluate its impact on mortality.
METHODS: The study used two waves of data from China Health and Retirement Longitudinal Study (CHARLS) in 2011 and 2013. The prevalence and incidence of mobility limitation were assessed using the methods recommended by the World Health Organization in the integrated care for older people guidelines, using the five-time sit-to-stand test as a screening and then the Short Physical Performance Battery assessment for diagnosis. Multivariable logistic regression was used to analyze the association between mobility limitation and death.
RESULTS: Of the 5507 participants with complete baseline data, 1486 had limited mobility, and 4021 had intact mobility at baseline; 4093 participants completed follow-up assessment 2 years later, and 189 died between the baseline and follow-up assessments. Of the 2828 participants with intact mobility at baseline who completed the follow-up mobility assessment, 408 developed mobility limitation. The standardized prevalence was 30.4% (95% CI = 28.8-32.1 %). The standardized incidence of mobility limitation in 2 years was 18.1% (95% CI = 15.8-20.4 %). A total of 189 patients died during the follow-up period. After adjusting for sociodemographic factors and chronic diseases, mobility limitation was associated with an increased risk of death (odds ratio = 1.84, 95% CI = 1.33-2.55, P < .001).
CONCLUSIONS: The standardized prevalence of mobility limitation in Chinese older adults living in the community was 30.4%, and the standardized incidence was 18.1%. Mobility limitation significantly predicts 2-year death in older adults. This suggests that early screening, assessment of intrinsic capacity (particularly locomotion domain) as well as tailored interventions to tackle mobility limitation in older adults might reduce mortality.
The purpose of this open-label extension to the Depressed MIND 3 study will be to gather data on longer-term benefits and safety in patients with late-life depression (LLD). Neuronal nicotinic receptors have long been known to play a critical role in memory function in preclinical studies, with nicotine improving attention, learning, and memory function. This may be particularly relevant in LLD, which is characterized both by affective symptoms and broad cognitive deficits. The co-occurrence of cognitive deficits in LLD is a clinically relevant phenotype characterized by significant disability and poor antidepressant response. Cognitive deficits can persist even with successful antidepressant treatment and increase the risk of depression relapse. Despite the clinical importance of cognitive deficits in LLD, there are no established treatments that specifically target cognition in this population. The lack of clear pharmacologic targets and therapies aimed at improving cognitive deficits in depression is a substantial deficiency in current therapeutics.

Investigators propose that modulation of the cognitive control network by stimulation of cholinergic system nicotinic acetylcholine receptors will improve both mood and cognition in depressed elders. The study is an open-label extension of a randomized double blind placebo control trial that will enroll 80 participants over a 3-year period. After randomization and completion of the blinded study phase, participants will be eligible for this 12-week extension.

At the completion of Week-12 visit of the Depressed MIND -3, all eligible subjects will be offered enrollment in the open label extension study. Study visits during the treatment period for all subjects will occur approximately 3 weeks with flexible dose titration. This will be followed by a 1-3 week taper phase. The total duration of study participation will be approximately 15 weeks.
Nitric Oxide (NO) acts as double-edged sword, which induces and prevents cell death, depending on various factors. The mechanism for the NO regulation of cells is not fully understood. The present invention provides experiment design methods and therapy design methods leveraging viable hypothesis supported by current research findings. This invention determines the effects of NO by controlling the majority parameters such as the steady-state concentration of NO, duration of NO exposure and the local level of oxygen. The experiment designs are structured to improve understanding of NO regulation of cells, and further can be directly adapted for therapy design. The invention directs these experiment design and therapy design methods to the study and treatment of cancer. In an application, the effects of exogenous NO on inducible Nitric Oxide Synthase (iNOS) expression and signal transduction in ovarian cancer is applied to drug discovery and therapy design for ovarian and other cancers.
