BACKGROUND: Post-stroke depression (PSD) affects approximately one-third of stroke survivors, leading to adverse outcomes in rehabilitation, reduced quality of life, and increased mortality rates. Despite these implications, the underlying causes of PSD remain unclear, posing challenges for prevention and treatment. Echinacoside (ECH), a natural compound with known neuroprotective and antidepressant properties, holds significant therapeutic potential for PSD. However, the precise mechanism of its action remains unknown.
PURPOSE: To unravel the specific mechanism through which ECH alleviates PSD by exploring the intricate interplay between ECH and Nrf2, as well as its impact on the BDNF/TrkB signaling axis.
STUDY DESIGN AND METHODS: A rat PSD model was established though middle cerebral artery occlusion coupled with chronic unpredictable mild stress, followed by ECH treatment. The rats' depressive state was evaluated using the sucrose preference test and force swimming test. Brain damage was assessed through TTC staining, Nissl staining, and TUNEL assay. The multifaceted mechanism of ECH in PSD was investigated using immunofluorescence, immunohistochemistry, RT-qPCR, dual-luciferase assay, and western blotting. Additionally, the interaction between ECH and Nrf2 was explored through molecular docking and microscale thermophoresis.
RESULTS: Our findings unveiled a novel facet of ECH action, demonstrating its unique ability to upregulate Nrf2 through acetylation within the hippocampus of PSD-affected rats (p < 0.05). Moreover, ECH showcased its distinctive potential by enhancing BDNF transcriptional activity, activating the BDNF/TrkB signaling axis, and orchestrating a comprehensive response against oxidative stress and apoptosis, thereby alleviating PSD symptoms in rats (p < 0.05).
CONCLUSIONS: This study not only provides insights into the pivotal role of Nrf2 in mediating the BDNF/TrkB axis activation by ECH but also highlights the novelty of ECH's mechanism in addressing PSD. The elucidation of these unique aspects positions ECH as a groundbreaking candidate for further exploration and development in the realm of PSD intervention.
(1) Background: The elderly suffer from functional constipation (FC), whose causes are not fully known, but nutritional factors may play a role. The aim of the present study was to assess the effect of a low FODMAP diet supplemented with L-tryptophan (TRP) on its metabolism and symptoms of functional constipation in elderly patients. (2) Methods: This study included 40 people without abdominal complaints (Group I, controls) and 60 patients with FC, diagnosed according to the Rome IV Criteria (Group II). Two groups were randomly selected: Group IIA (n = 30) was qualified for administration of the low FODMAP diet, and the diet of patients of Group IIB (n = 30) was supplemented with 1000 mg TRP per day. The severity of abdominal symptoms was assessed with an abdominal pain index ranging from 1 to 7 points (S-score). The concentration of TRP and its metabolites, 5-hydroxyindoleacetic acid (5-HIAA), kynurenine (KYN), and 3-indoxyl sulfate (3-IS) in urine were determined using the LC-MS/MS method. (3) Results: In Group II, 5-HIAA concentration in urine was lower, and KYN and 3-IS concentrations were higher than in the control group. A negative correlation was found between the S-score and urinary concentration of 5-HIAA (p < 0.001), and 3-IS concentration was positively correlated with the S-score. However, the correlation between the S-score and 3-IS concentration was negative (p < 0.01). After a dietary intervention, 5-HIAA concentration increased in both groups, and the severity of symptoms decreased, but the decrease was more pronounced in Group IIB. (4) Conclusion: A low FODMAP diet supplemented with L-tryptophan has beneficial effects in elderly patients suffering from functional constipation.
INTRODUCTION: Although there are some established prognostic evaluation models for clear cell renal cell carcinoma (ccRCC), more robust postoperative prognostic evaluation model is urgently needed. Our study intends to explore new clinical and pathological prognostic factors related to non-metastatic ccRCC, which help to establish a better prognostic risk evaluation model in non-metastatic ccRCC.
PATIENTS AND METHODS: A retrospective cohort study was conducted in non-metastatic ccRCC patients spanning from 2010 to 2018. Clinical and pathological factors of these patients were collected. Cox regression analysis was employed to assess the relationship between these factors and disease-free survival (DFS), and a nomogram risk prediction model was also constructed.
RESULTS: A total of 1467 patients were ultimately included, comprising 994 men (67.8%), with 800 patients aged between 40 and 60 years old (54.5%), and 80 patients (5.5%) experiencing relapse or metastasis of ccRCC within three years after operation. The follow-up duration ranged from 39 to 146 months. Univariate and multivariate Cox regression analysis identified five independent prognostic factors of DFS (P < 0.05) including sex, tumor maximum diameter, T stage, lactate dehydrogenase (LDH), and basophils. Leveraging these five factors, we established a prognostic evaluation model demonstrating good predictive efficacy.
CONCLUSION: Male, tumor maximum diameter, T stage, LDH, and basophils serve as prognostic indicators for DFS in patients with non-metastatic ccRCC. Patients with high scores based on our model exhibit an elevated likelihood of recurrence or metastasis, thereby potentially selecting postoperative patients with high risk for adjuvant therapy.
Up to 50% of patients with Crohn's disease develop a stricture within 10 years of diagnosis. Crohn's strictures can compose of inflammation, fibrosis or smooth muscle expansion and usually a combination of these. There have been numerous new developments in imaging modalities in determining the composition of Crohn's strictures. Magnetic resonance imaging remains the best upfront imaging modality to characterize Crohn's strictures. Gastrointestinal ultrasound (GIUS) has an increasing role in clinical practice, particularly for monitoring stricture response as a treat-to-target tool. Novel imaging techniques to differentiate between fibrosis and inflammatory strictures have been developed including contrast-enhanced GIUS, strain or shear wave elastography with GIUS and multiple new magnetic resonance imaging (MRI) protocols, including diffusion weighted, delayed contrast enhancement and magnetization transfer MR protocols. However, these techniques require further validation and standardization. Regarding therapeutics, anti-tumor necrosis agents with a treat-to-target strategy have the highest quality evidence in treating strictures and can lead to stricture regression in some cases. Endoscopic balloon dilatation remains a mainstay in the treatment algorithm of treating predominantly fibrostenotic Crohn's strictures, particularly those which are symptomatic, < 5 cm in length and not causing prestenotic dilatation. Endoscopic balloon dilatation has greater effectiveness in anastomotic strictures. Surgery remains an important treatment option in Crohn's strictures, with segmental resection and stricturoplasty having their own advantages and disadvantages. Kono-S anastomosis may be superior to conventional anastomosis for endoscopic recurrence; however, further high-quality studies are required to confirm this. Using risk stratification models such as the BACARDI risk model is important to guide management decisions between a medical and surgical approach. Early post-operative medical prophylaxis with an advanced therapy is an important consideration to prevent disease recurrence. This review expands on the above topics, highlights research gaps and provides a suggested investigation and management pathway in stricturing Crohn's disease.
BACKGROUND: Polycystic ovary syndrome (PCOS) is a heterogeneous metabolic and endocrine disorder that causes anovulatory infertility and abnormal folliculogenesis in women of reproductive age. Several studies have revealed inflammation in PCOS follicles, and recent evidence suggests that Berberine (BBR) effectively reduces inflammatory responses in PCOS, however, the underlying mechanisms remain unclear.
PURPOSE: To determine the underlying mechanisms by which BBR alleviates inflammation in PCOS.
STUDY DESIGN: Primary human GCs from healthy women and women with PCOS, and KGN cells were used for in vitro studies. ICR mice were used for in vivo studies.
METHODS: Gene expression was measured using RT-qPCR. HAS2, inflammatory cytokines, and serum hormones were assayed by ELISA. Protein expression profiles were assayed by Western blot. Chronic low-grade inflammatory mouse models were developed by intraperitoneal injection with LPS, and PCOS mouse models were established by subcutaneous intraperitoneal injection of DHEA. BBR and 4-MU were administered by gavage. Ovarian morphologic changes were evaluated using H&E staining. HAS2 expression in the ovary was assayed using Western blot and immunohistochemistry.
RESULTS: Our results confirmed that HAS2 expression and hyaluronan (HA) accumulation are closely associated with inflammatory responses in PCOS. Data obtained from in vitro studies showed that HAS2 and inflammatory genes (e.g., MCP-1, IL-1β, and IL-6) are significantly upregulated in PCOS samples and LPS-induced KGN cells compared to their control groups. In addition, these effects were reversed by blocking HAS2 expression or HA synthesis using BBR or 4-MU, respectively. Furthermore, HAS2 overexpression induces the expression of inflammatory genes in PCOS. These results were further confirmed in LPS- and DHEA-induced mouse models, where inflammatory genes were reduced by BBR or 4-MU, and ovarian morphology was restored.
CONCLUSIONS: Our results define previously unknown links between HAS2 and chronic low-grade inflammation in the follicles of women with PCOS. BBR exerts its anti-inflammatory effects by down-regulating HAS2. This study provides a novel therapeutic target for alleviating ovarian inflammation in women with PCOS.
BACKGROUND: Sarcopenia is an age-related condition characterized by progressive loss of muscle mass, strength, and function. The occurrence of sarcopenia has a huge impact on physical, psychological, and social health. Therefore, the prevention and treatment of sarcopenia is becoming an important public health issue.
METHOD: 35 six-week-old male C57BL/6 mice were randomly divided into five groups, one of which served as a control group, while the rest of the groups were constructed as a model of sarcopenia by intraperitoneal injection of D-galactose. The intervention with lactoferrin, creatine, and their mixtures, respectively, was carried out through gavage for 8 weeks. Muscle function was assessed based on their endurance, hanging time, and grip strength. The muscle tissues were weighed to assess the changes in mass, and the muscle RNA was extracted for myogenic factor expression and transcriptome sequencing to speculate on the potential mechanism of action by GO and KEGG enrichment analysis.
RESULT: The muscle mass (lean mass, GAS index), and muscle function (endurance, hanging time, and grip strength) decreased, and the size and structure of myofiber was smaller in the model group compared to the control group. The intervention with lactoferrin and creatine, either alone or combination, improved muscle mass and function, restored muscle tissue, and increased the expression of myogenic regulators. The combined group demonstrated the most significant improvement in these indexes. The RNA-seq results revealed enrichment in the longevity-regulated pathway, MAPK pathway, focal adhesion, and ECM-receptor interaction pathway in the intervention group. The intervention group may influence muscle function by affecting the proliferation, differentiation, senescence of skeletal muscle cell, and contraction of muscle fiber. The combined group also enriched the mTOR-S6K/4E-BPs signaling pathway, PI3K-Akt signaling pathway, and energy metabolism-related pathways, including Apelin signaling, insulin resistance pathway, and adipocytokine signaling pathway, which affect energy metabolism in muscle.
CONCLUSIONS: Lactoferrin and creatine, either alone or in combination, were found to inhibit the progression of sarcopenia by influencing the number and cross-sectional area of muscle fibers and muscle protein synthesis. The combined intervention appears to exert a more significant effect on energy metabolism.
Incubators in the developing world often lack humidifiers. The resting dry heat increases evaporative heat loss, the most prominent form of heat loss in premature infants due to their increased body surface area and immature stratum corneum. By potentially increasing humidity around the infants and decreasing evaporative heat losses, plastic bags may improve incubator warming. This study will compare the incidence of hypothermia in infants placed in an incubator for at least one hour randomized to receive standard incubator protocol (control group) or standard incubator protocol plus a plastic bag covering their torsos and lower extremities (intervention group). The axillary temperature of each infant will be taken before placement into the incubator and one hour later when the bag will be removed. Blood pressure, blood sugar, seizures, weight gain, hyperthermia, death, observation for respiratory distress syndrome, bronchopulmonary dysplasia, pneumothorax, sepsis, intraventricular hemorrhage, periventricular leukomalacia, necrotizing enterocolitis, intestinal perforation, pulmonary hemorrhage, incubator temperature, and humidity, and length of time in an incubator will be recorded throughout the hospitalization for all infants. With an estimated baseline hypothermia rate of 90% and a hypothesized 20% absolute risk reduction (22% relative risk reduction), a sample size of 118 will be used to have a power of 80% and a confidence interval of 95%.
Cohort of n=20 intensive care unit patients from the ages of 18 years will be collected. Participants of this cohort will have the opportunity to use the ICU Feel Better App every day from the second day after admission to the ICU until the day of discharge from ICU.
Participants in the intervention group will receive the EPO Feeding program and usual care. EPO Feeding program includes four, weekly group training sessions for parents of preschool children (aged 2-6) led by healthcare professionals. The intervention incorporates lessons and information (i.e., slide shows and handouts), group discussions, motivational interviewing, and other supplementary materials (e.g., stories, key messages, and educational videos) to improve parents' knowledge, skills, and behaviors regarding feeding preschool children. After each module, homework activities will be assigned to participants to help reinforce their knowledge, skills, and behaviors. The motivational interviewing will be conducted by healthcare professionals to provide individual support. Moreover, a WeChat group will be set up to facilitate parental involvement, learning, and communication.
Clonazolam is a designer triazolobenzodiazepine first synthesized in 1971 and is primarily used for its anxiolytic and sedative effects. It became a drug of misuse in 2012 and is known for its high potency and long duration of effect. Previous studies of nitrobenzodiazepines, such as nitrazepam, clonazepam, and flunitrazepam, as well as their metabolites, have demonstrated that bacterial species native to the gastrointestinal tract and active during postmortem (PM) decomposition are capable of affecting positivity and compound-to-metabolite ratios. Further studies have not been performed with clonazolam; however, it possesses the nitro functional group necessary for this biotransformation. To understand whether clonazolam may be similarly affected, PM cases (n = 288) and driving under the influence of drugs (DUID, n = 54) cases, positive for 8-aminoclonazolam reported by NMS Laboratories from 2020 to 2023, were selected for inclusion in this study. Concentrations of clonazolam and 8-aminoclonazolam were evaluated, and concurrent identification of parent drugs and their metabolites occurred less frequently in PM cases (n = 1, 0.30% of cases) than in DUID cases (n = 21, 38% of cases). The clonazolam concentration in one PM case was 13 ng/mL. In DUID cases, the median clonazolam concentration was 4.0 ng/mL and ranged from 2.0 to 10 ng/mL. 8-Aminoclonazolam had median concentrations of 13 and 19 ng/mL, with ranges 2.0-580 and 2.8-59 ng/mL for PM and DUID cases, respectively. Due to the ever-changing landscape of the designer benzodiazepine market, in vitro studies of PM microbial biotransformation of clonazolam are unavailable. The data reported herein provide valuable information in the absence of such studies and represent an alternative method of investigating this phenomenon as a potential cause of parent nitrobenzodiazepine to metabolite conversion.
Individuals vary in their ability to taste, and some individuals are more sensitive to certain tastes than others. Taste sensitivity is a predictor of various factors, such as diet, eating behavior, appetite regulation, and overall health. Furthermore, taste sensitivity can fluctuate within an individual over short to long periods of time: for example, in daily (diurnal) cycles, monthly (menstrual) cycles (in females), and yearly (seasonal) cycles. Understanding these temporal patterns is important for understanding individual eating habits and food preferences, particularly in the context of personalized and precision nutrition. This review provides a summary of the literature on taste sensitivity patterns across 3 temporal dimensions: daily, monthly, and yearly. Good evidence for diurnal patterns has been observed for sweet taste and fat taste, although the evidence is limited to rodent studies for the latter. Obese populations showed limited variation to sweet and fat taste sensitivities over a day, with limited variation in sweet taste sensitivity being linked to insulin resistance. There were mixed observations of temporal variation in sensitivity to sour and umami tastes, and there were no patterns in sensitivity to bitter taste. Menstrual patterns in sweet taste sensitivity were consistent with patterns in food intake. Other taste modality investigations had mixed findings that had little agreement across studies. Hormonal changes in females influence taste sensitivity to some degree, although the overall patterns are unclear. Seasonal patterns have been less well studied, but there is weak evidence that sweet, salty, and bitter taste sensitivities change across seasons. Differences in seasonal taste patterns have been observed in subgroups susceptible to mental health disorders, requiring further investigation. Patterns of taste sensitivity are evident across multiple temporal dimensions, and more research is needed to determine the influence of these patterns on food intake. Dysregulation of these patterns may also be a marker of certain diseases or health conditions, warranting further investigation. Notably, the alimentary tastes (umami, fat, and carbohydrate) are underrepresented in this research area and require additional investigation.
Provided is a virus antigen-immune coactivator-based bimolecular DNA vaccine, relating to the technical field of biomedicine. An expression vector is a DNA plasmid. A virus antigen is any virus immunogenic (antigen) molecule. An immune activate factor is a T-cell coactivator. An exogenous gene fragment for expressing a T-cell coactivator and a virus gene fragment of a virus antigen molecule are co-constructed in one DNA plasmid, and are simultaneously expressed in a same cell; such a bimolecule is used for activating a systematic immune response of a T-cell to a virus. Further provided is a bimolecular DNA vaccine technical platform. By means of the technical platform, a novel coronavirus S antigen fragment-immune coactivator-based bimolecular DNA vaccine is constructed for the immune prevention and control of novel coronaviruses.
BACKGROUND: Despite high satisfaction rates, reduction mammaplasty can have complications such as hematoma. Factors such as age, tobacco use, and comorbidities are known contributors, whereas the influence of race, BMI, certain medications, and blood pressure (BP) remain contentious. This study investigates hematoma risk factors in young women undergoing reduction mammaplasty.
STUDY DESIGN: A retrospective review was conducted including all female patients who underwent bilateral reduction mammaplasty at a single institution between 2012 and 2022. Data on demographics, BMI, medical comorbidities, surgical techniques, medications, and perioperative BP were collected. Differences between patients who developed a hematoma and those who did not were assessed using chi-square, Fisher's exact, and t -tests. The relationship between perioperative BP and hematoma formation was assessed using logistic regression.
RESULTS: Of 1,754 consecutive patients, 3% developed postoperative hematoma of any kind, with 1.8% returning to the operating room. Age (odds ratio [OR] 1.14, p = 0.01) and ketorolac use (OR 3.93, p = 0.01) were associated with hematoma development. Controlling for baseline BP, each 10 mmHg incremental increase in peak intraoperative BP (systolic BP [SBP]: OR 1.24, p = 0.03; mean arterial pressure: OR 1.24, p = 0.01) and postoperative BP (SBP: OR 1.41, p = 0.01; mean arterial pressure: OR 1.49, p = 0.01) escalated the odds of hematoma. Postoperative SBP variability also incrementally increased hematoma odds (OR 1.48, p < 0.01). Other factors, including race and surgical technique, were not significantly influential.
CONCLUSIONS: Age, ketorolac use, and intra- and postoperative BP peaks and variability are risk factors for hematoma in reduction mammaplasty. This emphasizes the importance of perioperative BP management and optimizing pain management protocols.
