Heart failure has always been a prevalent, disabling, and potentially life-threatening disease. For the treatment of heart failure, controlling cardiac remodeling is very important. In recent years, clinical trials have shown that sodium-glucose cotransporter-2 (SGLT-2) inhibitors not only excel in lowering glucose levels but also demonstrate favorable cardiovascular protective effects. However, the precise mechanisms behind the cardiovascular benefits of SGLT-2 inhibitors remain elusive. In this research, we assessed the impact of canagliflozin (CANA, an SGLT-2 inhibitor) on cardiac remodeling progression in mice and preliminarily elucidated the possible mechanism of action of the SGLT-2 inhibitor. Our results indicate that the administration of canagliflozin significantly attenuates myocardial hypertrophy and fibrosis and enhances cardiac ejection function in mice with isoprenaline (ISO)-induced cardiac remodeling. Notably, excessive mitophagy, along with mitochondrial structural abnormalities observed in ISO-induced cardiac remodeling, was mitigated by canagliflozin treatment, thereby attenuating cardiac remodeling progression. Furthermore, the differential expression of AMPK/PINK1/Parkin pathway-related proteins in ISO-induced cardiac remodeling was effectively reversed by canagliflozin, suggesting the therapeutic potential of targeting this pathway with the drug. Thus, our study indicates that canagliflozin holds promise in mitigating cardiac injury, enhancing cardiac function, and potentially exerting cardioprotective effects by modulating mitochondrial function and mitophagy through the AMPK/PINK1/Parkin pathway.
The pathological mechanism of sepsis-associated acute kidney injury (SA-AKI) is complex and involves tubular epithelial cell (TEC) death and immune cell activation. However, the interaction between tubular cell death and macrophage-mediated inflammation remains unclear. In this study, we uncovered that TEC ferroptosis was activated in SA-AKI. Increased levels of ferroptotic markers, including ferroptosis-related proteins, lipid peroxidation, malondialdehyde (MDA), 4-hydroxynonenal (4-HNE), reactive oxygen species (ROS), and mitochondrial damage, were observed in the kidney tissue of cecum ligation and puncture (CLP) and Lipopolysaccharide (LPS)-induced SA-AKI mouse models, which were subsequently suppressed by Ferrostatin-1 (Fer-1). In vitro experiments showed that Fer-1 inhibits LPS-induced mitochondrial damage, Fe2+ accumulation, and cytosolic ROS production. Moreover, it was found that TEC ferroptosis induced by promoted macrophage-inducible C-type lectin (Mincle) and its downstream expression and M1 polarization, which was mediated by the release of spliceosome-associated protein 130 (SAP130), an endogenous ligand of Mincle, from TEC. It was confirmed in vitro that the supernatant from LPS-stimulated TECs promoted Mincle expression and M1 polarization in macrophages. Further experiments revealed that M1 macrophages aggravated TEC ferroptosis, which was offset by neutralizing SAP130 or inhibiting Mincle expression. In addition, neutralizing the circulatory SAP130 blunted kidney ferroptosis and Mincle expression, as well as macrophage infiltration in the kidney of SA-AKI mice. In conclusion, the release of SAP130 from ferroptotic TECs promoted M1 macrophage polarization by triggering Mincle/syk/NF-κB signaling, and M1 macrophages, in turn, aggravated TEC ferroptosis.
PURPOSE: Lower back pain (LBP), mainly caused by intervertebral disk (IVD) degeneration (IDD), is widely prevalent worldwide and is a serious socioeconomic burden. Numerous factors may trigger this degenerative process, and microbial dysbiosis has recently been implicated as one of the likely causes. However, the exact relationship between IDD and the microbiome remains obscure. In this study, we investigated the gut microbiota composition and fecal metabolic phenotype and discussed the possible influences of microbiome dysbiosis on IDD.
METHODS: Fecal DNA was extracted from 16 fecal samples (eight rabbit models with IDD and eight sex- and age-matched healthy controls) and analyzed by high-throughput 16S rDNA sequencing. The fecal samples were also analyzed by liquid chromatography-mass spectrometry-based metabolomics. Multivariate analyses were conducted for the relationship between the omics data and IDD, linear discriminant analysis effect size was employed for biomarker discovery. Moreover, the Kyoto Encyclopedia of Genes and Genomes (KEGG) database was used to annotate the differential metabolites. The potential correlation between differential gut microbiota and metabolites was then assessed.
RESULTS: The 16S rDNA sequencing results showed that the β-diversity of the gut microbiota was significantly different between the IDD and control groups, with distinct abundance levels of dominant genera. Moreover, 59 metabolites were significantly upregulated and 91 were downregulated in IDD rabbits versus the controls. The KEGG enrichment analysis revealed that the top pathways remarkably impacted by IDD were tyrosine metabolism, amino sugar and nucleotide sugar metabolism, benzoate degradation, ABC transporters, ascorbate and aldarate metabolism, pantothenate and CoA biosynthesis, and pyrimidine metabolism. The correlation analysis revealed that DL-tyrosine and N-acetylmuramic acid were associated with multiple differential bacterial genera, including Helicobacter and Vibrio, which may play important roles in the process of IVD degeneration.
CONCLUSION: Our findings revealed that IDD altered gut microbiota and fecal metabolites in a rabbit model. The correlation analysis of microbiota and metabolome provides a deeper understanding of IDD and its possible etiopathogenesis. These results also provide a direction and theoretical basis for the clinical application of fecal transplantation, probiotics, and other methods to regulate gut microbiota in the treatment of LBP caused by IDD.
Doxorubicin is an anthracycline antitumor antibiotic with dose-dependent and cumulative cardiotoxicity. However, the necessity for serial cardiac evaluation is unknown in dogs without risk factors for dilated cardiomyopathy (DCM). This study aimed to investigate serial changes in echocardiographic and electrocardiographic measures in small- and medium-sized dogs after four doxorubicin doses. We included 17 dogs, weighting < 20 kg, with multicentric lymphoma. All dogs received doxorubicin over 30 min every 4 weeks as part of a multi-drug chemotherapy protocol. The average doxorubicin dose was 3.8 times per dog. Clinical cardiotoxicity was not observed during the monitoring period. The incidence of developing arrhythmia was not significantly associated with the number of doxorubicin doses received (P = 0.600). The development of valvular regurgitations and mitral regurgitation in these dogs was not significantly associated with the number of doxorubicin doses (P = 0.363 and P = 0.779, respectively). The other echocardiographic results were not significantly different between each evaluation. In conclusion, our results showed no significant cardiotoxicity under echocardiogram and electrocardiogram in small- and medium-sized dogs without risk factors for DCM after four doses of doxorubicin in a 30-minute infusion method.
Sleep deprivation (SD) is a recognized risk factor for atrial fibrillation (AF), yet the precise molecular and electrophysiological mechanisms behind SD-induced AF are unclear. This study explores the electrical and structural changes that contribute to AF in chronic partial SD. We induced chronic partial SD in Wistar rats using a modified multiple-platform method. Echocardiography demonstrated impaired systolic and diastolic function in the left ventricle (LV) of the SD rats. The SD rats exhibited an elevated heart rate and a higher low-frequency to high-frequency ratio in a heart-rate variability analysis. Rapid transesophageal atrial pacing led to a higher incidence of AF and longer mean AF durations in the SD rats. Conventional microelectrode recordings showed accelerated pulmonary vein (PV) spontaneous activity in SD rats, along with a heightened occurrence of delayed after-depolarizations in the PV and left atrium (LA) induced by tachypacing and isoproterenol. A Western blot analysis showed reduced expression of G protein-coupled receptor kinase 2 (GRK2) in the LA of the SD rats. Chronic partial SD impairs LV function, promotes AF genesis, and increases PV and LA arrhythmogenesis, potentially attributed to sympathetic overactivity and reduced GRK2 expression. Targeting GRK2 signaling may offer promising therapeutic avenues for managing chronic partial SD-induced AF. Future investigations are mandatory to investigate the dose-response relationship between SD and AF genesis.
Gamisoyo-san is an herbal formula widely used to treat psychological issues, menopausal symptoms, and dysmenorrhea. However, there is insufficient information on its safety profile. This study aimed to confirm the genotoxic and acute toxic potential of Gamisoyo-san. We performed a battery of tests, which included a bacterial reverse mutation test (Ames test) using five bacterial strains, an in vitro chromosomal aberration test using Chinese hamster lung (CHL) cells, an in vivo micronucleus test in mice, and human Cytochrome P450 (CYP450) and UDP-glucuronosyltransferase (UGT) assays. In the acute toxicity study, male and female rats were orally administered Gamisoyo-san 1000, 2000, or 5000 mg/kg and observed for 14 days. The activities of human CYP450s and UGTs were evaluated using recombinant baculosomes. Gamisoyo-san showed no signs of genotoxicity in the five bacterial strains, CHL cells, or mouse bone marrow cells. The acute toxicity test showed that the median lethal dose (LD50) of Gamisoyo-san was greater than 5000 mg/kg in rats. Gamisoyo-san inhibited the activities of CYP1A2, CYP2C19, and UGT1A1. In conclusion, Gamisoyo-san may not exert severe toxicological events or genotoxic effects at doses up to 5000 mg/kg in rats.
When discussing neurotransmitters whose signaling plays an important role in psychiatric illnesses, serotonin and dopamine may be the first that come to mind. Although serotonin and dopamine have significant roles, the impact of norepinephrine signaling is often overlooked. A growing body of evidence suggests that hyperactivity of norepinephrine signaling is an underlying issue in psychiatric disorders; conversely, there is evidence to suggest that deficits in the noradrenergic system are just as significant. Hence, alterations in noradrenergic activity are better characterized as dysregulation rather than a reductive, outdated formulation of "too much" or "too little" activity. Therefore, symptoms such as agitation, irritability, hyperarousal, and insomnia could be treated by targeting the underlying pathophysiology related to noradrenergic dysregulation with targeted treatments. In a recent consensus panel meeting, 5 experts reviewed the available evidence of altered noradrenergic activity and its potential role in some of the most common psychiatric disorders. This Academic Highlights article summarizes their discussion and presents the panel's conclusions.
Intrapartum blood glucose level has negative correlation to neonatal blood glucose level in type 1 diabetics. In gestational diabetes the correlation is less clear. In the view of current knowledge, it seems that moderately elevated intrapartum blood glucose may not cause neonatal hypoglycemia. There is no consensus of how to treat intrapartum blood glucose level in gestational diabetics. Some studies have implied that most of mothers with gestational diabetes would have normal blood glucose level during labour and hence would not need any intervention if their daily insulin dosage is less than 0,5-1 IU/kg.

Study participants are recruited into the study at Tampere University Hospital Maternity Ward when their daily insulin dose exceeds 30 IU. Randomization is done at 37th gestational week, if vaginal delivery is planned, and HbA1c is measured. Randomization envelope is opened at the delivery ward when active labour begins and treatment of blood glucose level is carried out accordingly. If insulin dose is 1 IU/kg or more, the participant is treated as in active treatment group despite of result of randomization. All neonates will receive milk substitute after birth in labour ward. Plasma glucose is measured immediately if neonate has symptoms of low blood sugar. If not, plasma glucose is measured approximately two hours after birth and after that every 4 hours until plasma glucose is 3,0 mmol/l or more in three consecutive measurements.
BACKGROUND: Dietary potassium (K+) has emerged as a modifiable factor for cardiovascular and kidney health in the general population, but its role in people with chronic kidney disease (CKD) is unclear. Here, we hypothesize that CKD increases the susceptibility to the negative effects of low and high K+ diets.
METHODS: We compared the effects of low, normal and high KChloride (KCl) diets and a high KCitrate diet for 4 weeks in male rats with normal kidney function and in male rats with CKD using the 5/6th nephrectomy model (5/6Nx).
RESULTS: Compared with rats with normal kidney function, 5/6Nx rats on the low KCl diet developed more severe extracellular and intracellular K+ depletion and more severe kidney injury, characterized by nephromegaly, infiltration of T cells and macrophages, decreased estimated glomerular filtration rate and increased albuminuria. The high KCl diet caused hyperkalemia, hyperaldosteronism, hyperchloremic metabolic acidosis and severe hypertension in 5/6Nx but not in sham rats. The high KCitrate diet caused hypochloremic metabolic alkalosis but attenuated hypertension despite higher abundance of the phosphorylated sodium chloride cotransporter (pNCC) and similar levels of plasma aldosterone and epithelial sodium channel abundance. All 5/6Nx groups had more collagen deposition than the sham groups and this effect was most pronounced in the high KCitrate group. Plasma aldosterone correlated strongly with kidney collagen deposition.
CONCLUSIONS: CKD increases the susceptibility to negative effects of low and high K+ diets in male rats, although the injury patterns are different. The low K+ diet caused inflammation, nephromegaly and kidney function decline, whereas the high K+ diet caused hypertension, hyperaldosteronism and kidney fibrosis. High KCitrate attenuated the hypertensive but not the pro-fibrotic effect of high KCl, which may be attributable to K+-induced aldosterone secretion. Our data suggest that especially in people with CKD it is important to identify the optimal threshold of dietary K+ intake.

FATALITIES ASSOCIATED WITH THE ADMINISTRATION OF SULFONAMIDES, ALTHOUGH RARE, HAVE OCCURRED DUE TO SEVERE REACTIONS, INCLUDING STEVENS-JOHNSON SYNDROME, TOXIC EPIDERMAL NECROLYSIS, FULMINANT HEPATIC NECROSIS, AGRANULOCYTOSIS, APLASTIC ANEMIA, AND OTHER BLOOD DYSCRASIAS.

SULFONAMIDES, INCLUDING SULFONAMIDE-CONTAINING PRODUCTS SUCH AS ERYTHROMYCIN ETHYLSUCCINATE AND SULFISOXAZOLE ACETYL FOR ORAL SUSPENSION, SHOULD BE DISCONTINUED AT THE FIRST APPEARANCE OF SKIN RASH OR ANY SIGN OF ADVERSE REACTION. In rare instances, a skin rash may be followed by a more severe reaction, such as Stevens-Johnson syndrome, toxic epidermal necrolysis, hepatic necrosis, and serious blood disorders. (See PRECAUTIONS.)

Clinical signs such as sore throat, fever, pallor, rash, purpura, or jaundice may be early indications of serious reactions.

There have been reports of hepatic dysfunction, with or without jaundice, occurring in patients receiving oral erythromycin products.

Cough, shortness of breath, and pulmonary infiltrates are hypersensitivity reactions of the respiratory tract that have been reported in association with sulfonamide treatment.

The sulfonamides should not be used for the treatment of group A beta-hemolytic streptococcal infections. In an established infection, they will not eradicate the streptococcus and, therefore, will not prevent sequelae such as rheumatic fever.

Pseudomembranous colitis has been reported with nearly all antibacterial agents, including erythromycin ethylsuccinate and sulfisoxazole acetyl for oral suspension, and may range in severity from mild to life-threatening. Therefore, it is important to consider this diagnosis in patients who present with diarrhea subsequent to the administration of antibacterial agents.

Treatment with antibacterial agents alters the normal flora of the colon and may permit overgrowth of clostridia. Studies indicate that a toxin produced by Clostridium difficile is one primary cause of “antibiotic-associated colitis”.

After diagnosis of pseudomembranous colitis has been established, therapeutic measures should be initiated. Mild cases of pseudomembranous colitis usually respond to drug discontinuation alone. In moderate to severe cases, consideration should be given to management with fluids and electrolytes, protein supplementation, and treatment with an antibacterial drug clinically effective against Clostridium difficile colitis.

There have been reports suggesting that erythromycin does not reach the fetus in adequate concentration to prevent congenital syphilis. Infants born to women treated during pregnancy with erythromycin for early syphilis should be treated with an appropriate penicillin regimen.

Rhabdomyolysis with or without renal impairment has been reported in seriously ill patients receiving erythromycin concomitantly with lovastatin. Therefore, patients receiving concomitant lovastatin and erythromycin should be carefully monitored for creatine kinase (CK) and serum transaminase levels. (See package insert for lovastatin.)
Patients should be informed of the availability of a Medication Guide and they should be instructed to read the Medication Guide before taking carbamazepine tablets.

Patients should be made aware of the early toxic signs and symptoms of a potential hematologic problem, as well as dermatologic, hypersensitivity or hepatic reactions. These symptoms may include, but are not limited to, fever, sore throat, rash, ulcers in the mouth, easy bruising, lymphadenopathy and petechial or purpuric hemorrhage, and in the case of liver reactions, anorexia, nausea/vomiting, or jaundice. The patient should be advised that, because these signs and symptoms may signal a serious reaction, that they must report any occurrence immediately to a physician. In addition, the patient should be advised that these signs and symptoms should be reported even if mild or when occurring after extended use.

Patients should be advised that serious skin reactions have been reported in association with carbamazepine. In the event a skin reaction should occur while taking carbamazepine, patients should consult with their physician immediately (see WARNINGS).

Patients should be advised that anaphylactic reactions and angioedema may occur during treatment with carbamazepine (see WARNINGS). Advise patients to immediately report signs and symptoms suggesting angioedema (swelling of the face, eyes, lips, or tongue, or difficulty in swallowing or breathing) and to stop taking the drug until they have consulted with their healthcare provider.

Patients, their caregivers, and families should be counseled that AEDs, including carbamazepine, may increase the risk of suicidal thoughts and behavior and should be advised of the need to be alert for the emergence or worsening of symptoms of depression, any unusual changes in mood or behavior, or the emergence of suicidal thoughts, behavior, or thoughts about self-harm. Behaviors of concern should be reported immediately to healthcare providers.

Carbamazepine may interact with some drugs. Therefore, patients should be advised to report to their doctors the use of any other prescription or nonprescription medications or herbal products.

Caution should be exercised if alcohol is taken in combination with carbamazepine therapy, due to a possible additive sedative effect.

Since dizziness and drowsiness may occur, patients should be cautioned about the hazards of operating machinery or automobiles or engaging in other potentially dangerous tasks.

Patients should be encouraged to enroll in the NAAED Pregnancy Registry if they become pregnant. This registry is collecting information about the safety of antiepileptic drugs during pregnancy. To enroll, patients can call the toll free number 1-888-233-2334 (see WARNINGS, Usage in Pregnancy subsection).
Background: Breast cancer is a common disease for which over 80% of women treated will still be in remission five years after diagnostic. They are a population that can benefit from support to reduce the risks associated with tobacco and alcohol consumptions. Moreover, it is well documented that health behaviors are part of a relational context. Thus, intervene on an individual level cannot suffice to apprehend health behaviors from a systemic perspective. Screening Brief Intervention and Referral to Treatment (SBIRT) program are evaluated for many years and are the reference model in health setting. However, despite national and international recommendations, SBIRT implementation in clinical routine is still very limited in oncology setting. Furthermore, intervene on multiple risk behaviors (contributing to many cancers, increasing the risk of second cancer, treatment morbidity and the risk of developing other chronic diseases) is recommended by several recent empirical studies. Involving the partner in the prevention process could help to develop healthy living environments. A SBIRT program, specifically dedicated to the oncological context and involving the partner may help to reduce tobacco and alcohol risk consumption. Methods/design: The study is a two-arm randomized trial including smoking couples. The intervention is a couple brief motivational intervention (CBMI) on tobacco/alcohol risk reduction, delivered in a single session and a booster session one month later. This intervention will be compared with an individual brief motivational intervention (IBMI) consisting a single brief motivational intervention and a booster session one month later, only delivered to the breast cancer patient; and the partner receive e-mail or postal brief advices. Measures are repeated at 6 weeks, 3 and 6 months post-intervention. The primary outcome is tobacco 7-day point prevalence abstinence (PPA) at 6 months.
