Aeromonas spp. are commonly found in the aquatic environment and have been responsible for motile Aeromonas septicemia (MAS) in striped catfish, resulting in significant economic loss. These organisms also cause a range of opportunistic infections in humans with compromised immune systems. Here, we conducted a genomic investigation of 87 Aeromonas isolates derived from diseased catfish, healthy catfish and environmental water in catfish farms affected by MAS outbreaks in eight provinces in Mekong Delta (years: 2012-2022), together with 25 isolates from humans with bloodstream infections (years: 2010-2020). Genomics-based typing method precisely delineated Aeromonas species while traditional methods such as aerA PCR and MALDI-TOF were unable identify A. dhakensis. A. dhakensis was found to be more prevalent than A. hydrophila in both diseased catfish and human infections. A. dhakensis sequence type (ST) 656 followed by A. hydrophila ST251 were the predominant virulent species-lineages in diseased catfish (43.7 and 20.7 %, respectively), while diverse STs were found in humans with bloodstream infections. There was evidence of widespread transmission of ST656 and ST251 on striped catfish in the Mekong Delta region. ST656 and ST251 isolates carried a significantly higher number of acquired antimicrobial resistance (AMR) genes and virulence factors in comparison to other STs. They, however, exhibited several distinctions in key virulence factors (i.e. lack of type IV pili and enterotoxin ast in A. dhakensis), AMR genes (i.e. presence of imiH carbapenemase in A. dhakensis), and accessory gene content. To uncover potential conserved proteins of Aeromonas spp. for vaccine development, pangenome analysis has unveiled 2202 core genes between ST656 and ST251, of which 78 proteins were in either outer membrane or extracellular proteins. Our study represents one of the first genomic investigations of the species distribution, genetic landscape, and epidemiology of Aeromonas in diseased catfish and human infections in Vietnam. The emergence of antimicrobial resistant and virulent A. dhakensis strains underscores the needs of enhanced genomic surveillance and strengthening vaccine research and development in preventing Aeromonas diseases in catfish and humans, and the search for potential vaccine candidates could focus on Aeromonas core genes encoded for membrane and secreted proteins.

OBJECTIVE: Extent of resection (EOR) is the most important modifiable prognostic variable for pediatric patients with posterior fossa ependymoma. An understanding of primary and recurrent ependymoma complications is essential to inform clinical decision-making for providers, patients, and families. In this study, the authors characterize postsurgical complications following resection of primary and recurrent pediatric posterior fossa ependymoma in a molecularly defined cohort.
METHODS: The authors conducted a 20-year retrospective single-center review of pediatric patients undergoing resection of posterior fossa ependymoma at the Hospital for Sick Children in Toronto, Canada. Complications were dichotomized into major and minor groups; EOR was compared across complication categories. The association between complication occurrence with length of stay (LOS) and mortality was also assessed using multivariable regressions.
RESULTS: There were 60 patients with primary resection included, 41 (68%) of whom were alive at the time of data collection. Gross-total resection was achieved in 33 (58%) of 57 patients at primary resection. There were no 30-day mortality events following primary and recurrent ependymoma resection. Following primary resection, 6 patients (10%) had posterior fossa syndrome (PFS) and 36 (60%) developed cranial neuropathies, 56% of which recovered within 1 year. One patient (1.7%) required a tracheostomy and 9 patients (15%) required gastrostomy tubes. There were 14 ventriculoperitoneal shunts (23%) inserted for postoperative hydrocephalus. Among recurrent cases, there were 48 recurrent resections performed in 24 patients. Complications included new cranial neuropathy in 10 patients (21%), of which 5 neuropathies resolved within 1 year. There were no cases of PFS following resection of recurrent ependymoma. Gastrostomy tube insertion was required in 3 patients (6.3%), and 1 patient (2.0%) required a tracheostomy. Given the differences in the location of tumor recurrence, a direct comparison between primary and recurrent resection complications was not feasible. Following multivariate analysis adjusting for sex, age, molecular status, and EOR, occurrence of major complications was found to be associated with prolonged LOS but not mortality.
CONCLUSIONS: These results detail the spectrum of postsurgical morbidity following primary and recurrent posterior fossa ependymoma resection. The crude complication rate following resection of infratentorial recurrent ependymoma was lower than that of primary ependymoma, although a statistical comparison revealed no significant differences between the groups. These results should serve to inform providers of the morbidity profile following surgical management of posterior fossa ependymoma and inform perioperative counseling of patients and their families.
Physical training has been recommended as a non-pharmacological therapeutic strategy that can promote improvements in blood pressure levels in patients with systemic arterial hypertension (SAH). Resistance training (RT) has emerged due to the various benefits it promotes, including reducing blood pressure (BP) in this population, as improvements in heart rate variability (HRV) and endothelial function (EF). Guidelines suggest an intensity between 50% and 80% of 1 repetition maximum (1RM) in RT, reflecting a range of maximum repetitions between 9 and 26. However, there is a lack of studies that have made a direct comparison of the effect of different intensities in cardiovascular parameters of these patients. Therefore, the objective of this study will be to evaluate, acutely and chronically, the effect of RT intensity on BP, heart rate (HR), HRV, endothelial function, salivary concentrations of nitric oxide (NO) biomarker synthesis, also affectivity and rate of perceived exertion (RPE) of postmenopausal women with SAH. The study will be conducted in two stages, with two experiments: one acute and one chronic. In the acute experiment, with a crossover design, participants will perform the same RT session (with the order of these sessions being random), but in one condition they will train with 60% of 1RM and in another with 80% of 1RM. BP, HR and HRV will be measured before, at the end and for one hour after the session (hypotensive effect of the exercise). Affectivity will be measured before each test and at the end together with PSE. In the chronic study, participants will be randomized to one group that will train with 60% of 1RM and another group that will train with 80% of 1RM. Before, during and after the intervention, which will last 10 weeks, participants will be evaluated for BP, HR, affective responses and RPE, with EF, HRV and salivary concentrations of NO biomarkers measured before and after the intervention.
Bath additive in the form of powder, tablets, paste or cream, consists mainly or wholly of a whey concentrate containing more than 40% of dry substance (preferably 40-90%, especially 50-60%). Scents, detergents or emulsifiers (40-1000g. per kg. of dry whey substance), and colouring agents can be included. These whey concentrates can be stored without decomposing and developing an unpleasant odour. Whey protects human skin and exerts a vitalising effect.
In addition to the standard enrollment, 6-month, and completion incentives, the subject will be told that they can weigh in again any time before the study ends when they think they have lost 5% of their initial body weight. If they did meet their 5% goal, they will begin receiving a bi-weekly premium discount during the next pay period for a total duration of 12 months. Subjects that do not meet the 5% cut off during a weigh in are allowed to re-weigh themselves as many times as they like although they are encouraged to do so when they think they have met their target weight. Their premium goes back to normal price after this 12-month discount ends.
BACKGROUND: In primary shoulder arthroplasty (SA), intravenous (IV) cefazolin has demonstrated lower rates of infectious complications when compared to IV vancomycin. However, previous analyses included SA cohorts with both complete and incomplete vancomycin administration. Therefore, it is currently unclear whether cefazolin still maintains a prophylactic advantage to vancomycin when it is appropriately indicated and sufficiently administered at the time of surgical incision. This study evaluated the comparative efficacy of cefazolin and complete vancomycin administration for surgical prophylaxis in primary shoulder arthroplasty with respect to infectious complications.
METHODS: A retrospective cohort study was conducted utilizing a single institution total joint registry database, where all primary SA types (hemiarthroplasty, anatomic total shoulder arthroplasty, and reverse shoulder arthroplasty) performed between 2000 to 2019 for elective and trauma indications using IV cefazolin or complete vancomycin administration as the primary antibiotic prophylaxis were identified. Vancomycin was primarily indicated for patients with a severe self-reported penicillin or cephalosporin allergy and/or MRSA colonization. Complete administration was defined as at least 30 minutes of antibiotic infusion prior to incision. All included SA had at least 2 years of clinical follow-up. Multivariable Cox proportional hazard regression was used to evaluate all-cause infectious complications including survival free of prosthetic joint infection (PJI).
RESULTS: The final cohort included 7177 primary SA, 6879 (95.8%) received IV cefazolin and 298 (4.2%) received complete vancomycin administration. Infectious complications occurred in 120 (1.7%) SA leading to 81 (1.1%) infectious reoperations. Of the infectious complications, 41 (0.6%) were superficial infections and 79 were (1.1%) PJIs. When categorized by administered antibiotics, there were no differences in rates of all infectious complications (1.6% vs. 2.3%; P = .352), superficial complications (0.5% vs. 1.3%; P = .071), PJI (1.1% vs. 1.0%; P = .874), or infectious reoperations (1.1% vs. 1.0%; P = .839). On multivariable analyses, complete vancomycin infusion demonstrated no difference in rates of infectious complications compared to cefazolin administration (hazard ratio [HR], 1.50 [95% confidence interval (CI), 0.70 to 3.25]; P = .297), even when other independent predictors of PJI (male sex, prior surgery, and Methicillin-resistant Staphylococcus aureus colonization) were considered.
CONCLUSIONS: In comparison to cefazolin, complete administration of vancomycin (infusion to incision time greater than 30 minutes) as the primary prophylactic agent does not adversely increase the rates of infectious complications and PJI. Prophylaxis protocols should promote appropriate indications for the use of cefazolin or vancomycin, and when necessary, ensure complete administration of vancomycin to mitigate additional infectious risks after primary SA.
OBJECTIVE: Non-alcoholic fatty liver disease (NAFLD) is a clinicopathological syndrome characterized by excessive fat deposition in hepatocytes caused by non-alcoholic liver injury. Porphyromonas gingivalis (P.g) is the main pathogen causing periodontitis, which can aggravate the progression of NAFLD in our previously study. The objective of this study was to further investigate the pathogenesis and moleculer michanisma of NAFLD aggravated by P.g.
METHODS: A mouse model of NAFLD was established, and the changes of inflammatory factors and NF-κB signaling pathway in liver tissue and L-02 cells were analyzed by transcriptome sequencing, Western blot, IHC and RT-PCR. In addition, the NF-κB signaling pathway inhibitor QNZ and ferroptosis inhibitor Fer-1 were used to analyze the relationship between NF-κB signaling pathway and ferroptosis in vitro.
RESULTS: In vivo and in vitro experiments, P.g can induce liver inflammation and activate NF-κB signaling pathway. At the same time, P.g promotes ferroptosis and inflammation in L-02 in vitro. QNZ alleviates ferroptosis and inflammatory activation in L-02. Fer-1 can relieve the L-02 inflammation caused by P.g products.
CONCLUSION: Porphyromonas gingivalis can induce ferroptosis and inflammation in hepatocytes and further worsen liver lesions. The mechanism of ferroptosis in hepatocytes depends on NF-κB signaling pathway, which provides a new strategy for clinical treatment and prevention of NAFLD.
Hemorrhagic shock (HS), a leading cause of preventable death, is characterized by severe blood loss and inadequate tissue perfusion. Reoxygenation of ischemic tissues exacerbates organ damage through ischemia-reperfusion injury. SUMOylation has been shown to protect neurons after stroke and is upregulated in response to cellular stress. However, the role of SUMOylation in organ protection after HS is unknown. This study aimed to investigate SUMOylation-mediated organ protection following HS. Male Wistar rats were subjected to HS (blood pressure of 40 ± 2 mmHg, for 90 min) followed by reperfusion. Blood, kidney, and liver samples were collected at various time points after reperfusion to assess organ damage and investigate the profile of SUMO1 and SUMO2/3 conjugation. In addition, human kidney cells (HK-2), treated with the SUMOylation inhibitor TAK-981 or overexpressing SUMO proteins, were subjected to oxygen and glucose deprivation to investigate the role of SUMOylation in hypoxia/reoxygenation injury. The animals presented progressive multiorgan dysfunction, except for the renal system, which showed improvement over time. Compared to the liver, the kidneys displayed distinct patterns in terms of oxidative stress, apoptosis activation, and tissue damage. The global level of SUMO2/3 in renal tissue was also distinct, suggesting a differential role. Pharmacological inhibition of SUMOylation reduced cell viability after hypoxia-reoxygenation damage, while overexpression of SUMO1 or SUMO2 protected the cells. These findings suggest that SUMOylation might play a critical role in cellular protection during ischemia-reperfusion injury in the kidneys, a role not observed in the liver. This difference potentially explains the renal resilience observed in HS animals when compared to other systems.

This systematic review aimed to summarize the most recent data on changes in brain structure and function in premenstrual dysphoric disorder (PMDD) as well as elucidate the possible correlations between these findings and symptom severity. Articles published in PubMed, EMBASE, ScienceDirect, PsycInfo, Web of Science, and Scopus from inception until April 2023 were systematically reviewed according to the PICO framework: population (women with PMDD), intervention (neuroimaging study), control (healthy subjects), and outcome (neuroimaging changes). In total, 1026 individuals were included from controlled (n = 22) and non-controlled (n = 2) trials. Among them, 608 had PMDD, and 418 were healthy controls. Different neuroimaging methods were addressed, such as task-based functional magnetic resonance imaging (MRI), resting-state functional MRI, proton magnetic resonance spectroscopy, diffusion tensor imaging, proton emission tomography, and structural MRI. Despite the absence of consensual results, several brain structures have been implicated in PMDD, including the prefrontal cortex, amygdala, hippocampus, insula, basal ganglia, and cerebellum. In addition, some brain changes are related to the intensity of symptoms and phases of the menstrual cycle, such as the correlation between depressive symptoms and increased serotonin transporter binding potential in the midbrain during the luteal phase.
The radiation prescription dose ranges from 45 Gy in 3 Gy fractions to 60 Gy in 4 Gy fractions. Patients will be assigned to receive 1 of 3 doses of radiation therapy, based on when they joined the study. The first group of at least 3 participants will receive the lowest total radiation dose. If the first dose is tolerated well by the first group of participants in this study, then the next group of participants will receive the second, higher dose of radiation. If this dose is tolerated, then a third group will be treated at the highest dose.
The CSAAC group (chlorhexidine-based soap + ethyl alcohol + alcoholic chlorhexidine): skin preparation process with 4% chlorhexidine-based soap for a period of 5 minutes, followed by a sterile and soaked with 70% alcohol compress. After removing the chlorhexidine-based soap excess, antisepsis was performed with alcoholic chlorhexidine and surgical drapes and gowns. Cultures were performed in the mannitol and EMB (Eosin Methylene Blue) media after being collected at the pre-skin preparation, post-skin preparation process and end of the surgical procedure.
Effectiveness of carvedilol in patients younger than 18 years of age has not been established. 

In a double-blind trial, 161 children (mean age 6 years, range 2 months to 17 years; 45% less than 2 years old) with chronic heart failure [NYHA class II-IV, left ventricular ejection fraction < 40% for children with a systemic left ventricle (LV), and moderate-severe ventricular dysfunction qualitatively by echo for those with a systemic ventricle that was not an LV] who were receiving standard background treatment were randomized to placebo or to 2 dose levels of carvedilol. These dose levels produced placebo-corrected heart rate reduction of 4 to 6 heart beats per minute, indicative of β-blockade activity. Exposure appeared to be lower in pediatric subjects than adults. After 8 months of follow-up, there was no significant effect of treatment on clinical outcomes. Adverse reactions in this trial that occurred in greater than 10% of patients treated with carvedilol and at twice the rate of placebo-treated patients included chest pain (17% versus 6%), dizziness (13% versus 2%), and dyspnea (11% versus 0%).
Randomization of subjects will be performed at the end of 7 days of sensitive intravenous antibiotic administration, provided the subjects meet randomization criteria. Those who are randomized to the 14-day group will receive 7 more days of the same antibiotics, to make it a total of 14 days.
PURPOSE:To prepare the titled drug which can be thrusted directly into the diseased part and is resistant to break, by adding a drug to polylactic acid or a lactic acid-glycolic acid copolymer, mixing the composition under melting, removing the low-boiling components under reduced pressure, and molding the mixture in a mold. CONSTITUTION:A drug is added to a polylactic acid or a lactic acid-glycolic acid copolymer containing >=30wt% of polylactic acid, and mixed in an inert gas stream under heating and melting at 220-240 deg.C. At an arbitrary stage, the low-boiling volatile components in the polymer are removed under reduced pressure. The degassed mixture is molded preferably by compression molding to obtain a rod-shaped product such as a needle. After the completion of molding, the mold is preferably quenched to 5-10 deg.C, and the needle is released from the mold. The drug is e.g. a carcinostatic agent having a decomposition point of >=250 deg.C (e.g. 5-fluorouracil), etc. Since the formed product is free from voids because of the degassing process, it is resistant to break, and prevents the intrusion of low-boiling components and air into the body.
