e patient assessment and selection in this cohort.

Severe acute respiratory viral infections are frequency accompanied by multiple organ dysfunction, including acute kidney injury (AKI). In December 2019, the coronavirus disease 2019 (COVID-19) outbreak began in Wuhan, Hubei Province, China, and rapidly spread worldwide. While diffuse alveolar damage and acute respiratory failure are the main features of COVID-19, other organs may be involved, and the incidence of AKI is not well described. We assessed the incidence and clinical characteristics of AKI in patients with laboratory-confirmed COVID-19 and its effects on clinical outcomes.

We conducted a multicenter, retrospective, observational study of patients with COVID-19 admitted to two general hospitals in Wuhan from 5 January 2020 to 21 March 2020. Demographic data and information on organ dysfunction were collected daily. AKI was defined according to the KDIGO clinical practice guidelines. Early and late AKI were defined as AKI occurring within 72 h after admission or after 72 h, respectively.

Of thpment after 72 h of admission was related to prolonged hospitalization time.

Our findings show that admission SOFA score was an independent risk factor for AKI in COVID-19 patients, and patients with AKI had higher in-hospital mortality. PTX inhibitor mouse Moreover, AKI development after 72 h of admission was related to prolonged hospitalization time.

Up to now, tinnitus has been an almost non-treatable symptom affecting more than 18% of the population in industrialized countries. So far, there are only a few studies evaluating the effectiveness of acupuncture in tinnitus treatment, none of which include acute tinnitus (<3 months). The aim of this pilot study was to explore the feasibility of recruitment and adherence to acupuncture conducted according to the principles of traditional Chinese medicine in patients with acute idiopathic tinnitus and to assess effect sizes on subjective and objective outcomes within a randomized controlled design.

After randomization patients of the control group received usual care (n = 23), and patients of the intervention group (n = 25) received 4 additional acupuncture treatments in a 4- to 6-week period. Tinnitus severity was assessed by means of a visual analogue scale as well as standardized and validated tinnitus questionnaires (Tinnitus Functional Index and 12-item Mini Tinnitus Questionnaire) at baseline and ecruitment, although patient adherence to treatment remained challenging. However, considering the small intergroup differences, procedures regarding the numbers of acupuncture sessions and the total period of the acupuncture treatment should be reconsidered. The results of this pilot study provide a good basis for future confirmatory trials.

Depressive disorders are the 4th leading cause of health problems and the 2nd leading cause of burden among all diseases. Almost all depressive disorder patients have cognitive impairments to a certain extend. link2 Studies about cognitive impairments in depression had been conducted, but whether cognitive dysfunctions are the cause or the effect is still not clear.

To analyze the process of working memory and cognitive flexibility impairments in a rat model of depression.

In this experimental study, chronic unpredictable mild stress (CUMS) was used as a model of depression in 30 rats (Rattus novergicus). Cognitive function was assessed with the Morris water maze and attentional set shifting test.

This study found a significant difference on day 21 in working memory (p = 0.002) and cognitive flexibility (p = 0.036), which continued to day 41 in working memory (p = 0.001) and cognitive flexibility (p = 0.020). In the CUMS model of depression, parameters peak on day 41 and reveal parameter changes in weight gain (p = 0.018), food intake (p < 0.001), changes in food intake (p = 0.001), and the sucrose preference (p = 0.005), elevated plus maze (p = 0.001), and light dark box tests (p = 0.020).

In a rat model of depression, cognitive impairment preceded depression, but it might be caused by anxiety-like behavior that occurred in early stimulation of chronic unpredictable mild stress.

The differential diagnosis between HL bone localization and other malignant or benign skeletal diseases is challenging. We report the case of a girl affected by classic HL, initially staged IVA because of supradiaphragmatic lymph nodes and skeletal involvement. After 6 ABVD (adriamycin, bleomycin, vinblastine, dacarbazine) cycles, positron emission tomography (PET) showed a complete metabolic response of the nodal localizations and a persistent, high metabolic activity of bone lesions. Salvage treatment followed by autologous stem cell transplant was carried out. After the transplant, the bone lesions maintained a high metabolic activity at PET. A targeted bone biopsy led to the diagnosis of a fibrous dysplasia excluding the presence of HL. To our knowledge, the concomitant presence of HL and fibrous dysplasia has not been previously reported. An in-depth evaluation of disease response to frontline treatment with a biopsy of the PET-hypercaptant bone lesions could have avoided overtreatment in this patient.Chronic stress can accelerate biological aging, offering one mechanism through which stress may increase age-related disease risk. Chronic activation of the sympathoadrenal system increases cellular energy production, resulting in cell stress that can initiate cellular senescence, a permanent state of cell growth arrest. Our previous research linked psychosocial stress with increased expression of senescence marker p16INK4a; however, less is known about the role of protective psychosocial factors in biological aging. We examined relationship closeness (perceived interconnectedness with one's spouse) as a protective buffer of the effects of stress on expression of the p16INK4a-encoding gene (CDKN2A) and transcription control pathways activated under cell stress. Seventy parents (Mage=43.2) completed interview-based and questionnaire measures of psychosocial stress and relationship closeness. Blood samples assessed CDKN2A expression and inferred activity of a priori-selected transcription factors Nrf2 and heat shock factors (HSFs) via genome-wide transcriptome profiling. Random intercept models adjusting for age, sex, and ethnicity/race revealed that perceived stress was associated with elevated CDKN2A expression for parents with low but not high closeness. Secondary bioinformatics analyses linked the interaction of perceived stress and relationship closeness to Nrf2 and HSF-1 activity. Findings identify relationship closeness as a protective factor that may buffer the impact of stress on cellular stress and senescence pathways.Although aging in the liver contributes to the development of chronic liver diseases such as NAFLD and insulin resistance, little is known about the molecular and metabolic details of aging in hepatic cells. To examine these issues, we used sequential oxidative stress with hydrogen peroxide to induce premature senescence in AML12 hepatic cells. The senescent cells exhibited molecular and metabolic signatures, increased SA-βGal and γH2A.X staining, and elevated senescence and pro-inflammatory gene expression that resembled livers from aged mice. Metabolic phenotyping showed fuel switching towards glycolysis and mitochondrial glutamine oxidation as well as impaired energy production. The senescent AML12 cells also had increased mTOR signaling and decreased autophagy which likely contributed to the fuel switching from β-oxidation that occurred in normal AML12 cells. Additionally, senescence-associated secretory phenotype (SASP) proteins from conditioned media of senescent cells sensitized normal AML12 cells to palmitate-induced toxicity, a known pathological effect of hepatic aging. In summary, we have generated senescent AML12 cells which displayed the molecular hallmarks of aging and also exhibited the aberrant metabolic phenotype, mitochondrial function, and cell signaling that occur in the aged liver.To evaluate the effects of short-term administration of enriched branched-chain amino acids (BCAAs) on subjects with pre-sarcopenia or sarcopenia, our quasi-experimental study enrolled 33 subjects (12 pre-sarcopenia/21 sarcopenia; 6 men/27 women; mean age 66.6 ± 10.3 years) to take one sachet (3.6 g) of enriched BCAA powder twice a day for five weeks followed by a discontinuation period of 12 weeks. We evaluated sarcopenic parameters, including grip strength, 6-meter gait speed, and bioelectrical-impedance-analysis-derived skeletal mass index (SMI), at baseline, 5 weeks, and 17 weeks. We found that both pre-sarcopenic and sarcopenic subjects showed improved SMI, gait speed, and grip strength at 5 weeks. However, all three parameters progressively declined at 17 weeks, especially SMI and grip strength in subjects aged less then 65 years and gait speed and grip strength in subjects aged ≥ 65 years. It thus appears that supplementation with enriched BCAAs for 5 weeks correlates with short-term positive effects on sarcopenic parameters but attenuation of those effects following discontinuation for 12 weeks.Sarcopenia, the decline in muscle mass and functionality during aging, might arise from age-associated endocrine dysfunction. Ghrelin is a hormone circulating in both acylated (AG) and unacylated (UnAG) forms with anti-atrophic activity on skeletal muscle. Here, we show that not only lifelong overexpression of UnAG (Tg) in mice, but also the deletion of ghrelin gene (Ghrl KO) attenuated the age-associated muscle atrophy and functionality decline, as well as systemic inflammation. Yet, the aging of Tg and Ghrl KO mice occurs with different dynamics while old Tg mice seem to preserve the characteristics of young animals, Ghrl KO mice features deteriorate with aging. However, young Ghrl KO mice show more favorable traits compared to WT animals that result, on the whole, in better performances in aged Ghrl KO animals. Treatment with pharmacological doses of UnAG improved muscle performance in old mice without modifying the feeding behavior, body weight, and adipose tissue mass. The antiatrophic effect on muscle mass did not correlate with modifications of protein catabolism. However, UnAG treatment induced a strong shift towards oxidative metabolism in muscle. Altogether, these data confirmed and expanded some of the previously reported findings and advocate for the design of UnAG analogs to treat sarcopenia.Aberrant activation of the cholesterol biosynthesis supports tumor cell growth. In recent years, significant progress has been made by targeting rate-limiting enzymes in cholesterol biosynthesis pathways to prevent carcinogenesis. However, precise mechanisms behind cholesterol degradation in cancer cells have not been comprehensively investigated. Here, we report that codon optimization of the orthologous cholesterol 7-desaturase, NVD-BM from Bombyx mori, significantly slowed melanoma cell proliferation and migration, and inhibited cancer cell engraftment in nude mice, by converting cholesterol to toxic 7-dehydrocholesterol. link3 Based on these observations, we established a synthetic genetic circuit to induce melanoma cell regression by sensing tumor specific signals in melanoma cells. The dual-input signals, RELA proto-oncogene (RELA) and signal transducer and activator of transcription 1 (STAT1), activated NVD-BM expression and repressed melanoma cell proliferation and migration. Mechanically, we observed that NVD-BM decreased Akt1-ser473 phosphorylation and inhibited cytoplasmic RELA translocation.
