BACKGROUND: Chronic obstructive pulmonary disease (COPD) is a preventable and treatable chronic condition characterized by progressive, partially reversible airflow obstruction. Osteoporosis represents a significant comorbidity in individuals with COPD. However, the incidence and prevalence of osteoporosis among the COPD population remain unclear in Taiwan. Therefore, our objective is to investigate the incidence and prevalence of osteoporosis in patients with COPD.
METHODS: In this cross-sectional study, we enrolled a COPD population retrieved from the Taiwan National Health Insurance Research Database (NHIRD) spanning the years 2003 to 2016. Osteoporosis patients were identified using diagnosis codes. The study included newly diagnosed COPD patients from 2003 to 2016. The case group comprised patients who developed osteoporosis or osteoporotic fractures after their COPD diagnosis. We calculated the prevalence and incidence of osteoporosis in individuals with COPD and conducted trend tests.
RESULTS: A total of 1,297,579 COPD patients were identified during the period from 2003 to 2016, with 275,233 of them in the osteoporosis group. The average prevalence of osteoporosis among individuals with COPD was 21.21% from 2003 to 2016 in Taiwan. The number of osteoporosis cases increased from 6,727 in 2003 to 24,184 in 2016. The prevalence of osteoporosis among COPD patients increased from 3.62% in 2003 to 18.72% in 2016. The number of osteoporosis cases among individuals with COPD continued to rise over the years, reaching its highest point in 2016 with 24,184 new cases. The incidence of osteoporosis fluctuated during the study period but generally remained around 3,000 cases per 100,000 person-years. Notably, there was a significant upward trend in incidence from 2003 to 2006, after which the trend stabilized and remained relatively constant.
CONCLUSIONS: Our study highlights an increase in both the prevalence and incidence of osteoporosis in individuals with COPD. Given the significant medical, economic, and social implications associated with osteoporosis, a comprehensive and robust assessment of its healthcare burden can offer valuable insights for healthcare system planning and policymaking.
INTRODUCTION: Robot-assisted laparoscopic radical prostatectomy (RALP) is a common procedure for the treatment of localised prostate cancer. Anorectal symptoms such as fecal incontinence (FI), rectal urgency or disturbed defecation have been reported after the operation. Anorectal function is dependent on the integrity of anal and pelvic nerves and muscles, rectal sensory function as well as rectal reservoir function. The aim of this study was to investigate the potential influence of RALP on anorectal physiological function and bowel symptoms.
MATERIALS AND METHODS: In this pilot study, 29 patients with localised prostate cancer scheduled for RALP were included. Anorectal physiology was used to measure rectal sensitivity and reservoir function as well as anal sphincter pressures. Bowel symptoms were measured by a bowel function questionnaire and a 2-week bowel function diary. Measurements were done before the operation and repeated at 6 months after the operation.
RESULTS: The study observed a significant postoperative increase in rectal sensory threshold for rectal balloon distention, from 20 to 40 mmHg, P < 0.001. This change is indicative of a decrease in rectal sensation after RALP. There were no other statistical significant differences in any of the physiological tests performed. Importantly, there was no change in any of the bowel symptoms after surgery.
CONCLUSION: This study showed that RALP may lead to impaired rectal sensory function. This finding did not, however, seem to have any influence on the patients´ postoperative clinical bowel function.
AIMS: The crosstalk between ferroptosis and neuroinflammation considerably impacts the pathogenesis of cerebral ischemia-reperfusion injury (CIRI). Neutral polysaccharide from Gastrodia elata (NPGE) has shown significant effects against oxidative stress and inflammation. This study investigated the potential effects of NPGE on CIRI neuropathology.
METHODS: The effects of NPGE were studied in a mouse model of ischemic stroke (IS) and in oxygen-glucose deprivation/reperfusion (OGD/R)-induced HT22 cells.
RESULTS: NPGE treatment decreased neurological deficits, reduced infarct volume, and alleviated cerebral edema in IS mice, and promoted the survival of OGD/R-induced HT22 cells. Mechanistically, NPGE treatment alleviated neuronal ferroptosis by upregulating GPX4 levels, lowering reactive oxygen species (ROS), malondialdehyde (MDA), and Fe2+ excessive hoarding, and meliorating GSH levels and SOD activity. Additionally, it inhibited neuroinflammation by down-regulating the level of IL-1β, IL-6, TNF-α, NLRP3, and HMGB1. Meanwhile, NPGE treatment alleviated ferroptosis and inflammation in erastin-stimulated HT22 cells. Furthermore, NPGE up-regulated the expression of NRF2 and HO-1 and promoted the translocation of NRF2 into the nucleus. Using the NRF2 inhibitor brusatol, we verified that NRF2/HO-1 signaling mediated the anti-ferroptotic and anti-inflammatory properties of NPGE.
CONCLUSION: Collectively, our results demonstrate the protective effects of NPGE and highlight its therapeutic potential as a drug component for CIRI treatment.
The invention comprises a polysaccharide comprising a fucosemethylpentose ether sulphate polymer having a molecular weight of about 5,000 to about 50,000, a specific rotation of [a ]25D = -119,6 DEG  in water, having in aqueous solution of 0,8% strength an ultra-violet absorption of very weak character in the range 256-280mm and being devoid of additional absorption maxima at 220-600 mm , having in 0,85 saline solution a relative viscosity of 1,2 being amorphous in character, containing the elements carbon, hydrogen, oxygen, sulphur, sodium, potassium and calcium, and being soluble in water.  The novel polysaccharide is obtained by fractional precipitation of an aqueous solution of crude fucoidin by means of a water-miscible organic solvent and collecting the polysaccharide precipitated as the concentration of the solvent in the solution is increased from about 45% to about 67%, or by treating the said aqueous solution with a quaternary ammonium compound, preferably one containing a carbon chain of 8 carbon atoms or more, collecting the water-insoluble precipitate, breaking up the obtained quaternary ammonium-polysaccharide complex by the addition of a strongly ionizable salt and collecting the polysaccharide from the obtained solution with a water-miscible organic solvent.  Both the fractional precipitation method and the quaternary ammonium complex formation may be used.  The new polysaccharide may be further purified by dialysis.  The product possesses anticoagulant and antilipemic activity.  An example also describes the extraction of crude fucoidin from ground, air-dried Fucus vesiculosus by heating with water, adding toluene, diluting and filtering the supernatant fluid, adding lead acetate solution and filtering, adding barium hydroxide to the filtrate, shaking the resultant precipitate with sulphuric acid, and dialysing for 3 days.  The non-dialysable material is concentrated in vacuo, freed of insoluble material by spinning at 12,000 g. for 45 minutes, the supernatant is poured into ethanol and dried in vacuo over P2O5.  The material is designated as crude fucoidin.ALSO:A new polysaccharide comprising a fucosemethylpentose ether sulphate polymer (obtained from crude fucoidin, see Group IV (a)) having anticoagulant and antilipemic properties, may be dispersed in any of the usual dosage unit forms of pharmaceutical preparations, for example, tablets, pills, capsules, solutions, powders, with any desired excipients, binders, fillers or other therapeutically inert ingredients.  For parenteral administration, the polysaccharide may be dissolved in any suitable liquid medium which is compatible with body fluids, e.g. physiological saline solution.  For oral administration, the polysaccharide may be employed with or without other physiological active ingredients in tablets, pills or capsules.
This study is a randomized controlled trial aiming to test the effect of the culturally-tailored in-office based intervention on physicians. A total of 24 Chinese physicians in the Washington DC and Philadelphia areas and a total of 24 eligible Chinese patients from each physician will be recruited for this study. Physicians and their patients are randomized into two groups: A and B. Physician in the intervention group (A) will receive mailed printed materials including a CRC physician guide, patient brochure, flip chart and a poster and two sessions of in-office training aimed to reinforce learning of the topic covered by the mailed materials and provide physicians with hands-on experience in using communication skills with standardized patients. Physicians in the control group (B) will receive nothing until the end of the study. Patients will be followed 12-month later after their completion of the baseline survey and their self-reported CRC screening status will be verified by chart audit.
BACKGROUND: Epilepsy is a common neurological disease; however, few if any of the currently marketed antiseizure medications prevent or cure epilepsy. Discovery of pathological processes in the early stages of epileptogenesis has been challenging given the common use of preclinical models that induce seizures in physiologically normal animals. Moreover, despite known sex dimorphism in neurological diseases, females are rarely included in preclinical epilepsy models.
METHODS: We characterized sex differences in mice carrying a pathogenic knockin variant (p.N1768D) in the Scn8a gene that causes spontaneous tonic-clonic seizures (TCs) at ∼3 months of age and found that heterozygous females are more resilient than males in mortality and morbidity. To investigate the cellular mechanisms that underlie female resilience, we utilized blood-brain barrier (BBB) and hippocampal transcriptomic analyses in heterozygous mice before seizure onset (pre-TC) and in mice that experienced ∼20 TCs (post-TC).
RESULTS: In the pre-TC latent phase, both sexes exhibited leaky BBB; however, patterns of gene expression were sexually dimorphic. Females exhibited enhanced oxidative phosphorylation and protein biogenesis, while males activated gliosis and CREB signaling. After seizure onset (chronic phase), females exhibited a metabolic switch to lipid metabolism, while males exhibited increased gliosis and BBB dysfunction and a strong activation of neuroinflammatory pathways.
CONCLUSION: The results underscore the central role of oxidative stress and BBB permeability in the early stages of epileptogenesis, as well as sex dimorphism in response to increasing neuronal hyperexcitability. Our results also highlight the need to include both sexes in preclinical studies to effectively translate results of drug efficacy studies.
Chronic pain, such as neuropathic pain, can lead to anxiety, depression, and other negative emotions, thereby forming comorbidities and increasing the risk of chronic pain over time. Both the infralimbic amygdala (IL) and the basolateral amygdala (BLA) are significantly associated with negative emotions and pain, and they are known to have reciprocal connections. However, the role of IL-BLA circuit pathways in neuropathic pain-induced anxiety and depression remains unexplored. Electroacupuncture (EA) is frequently employed in the treatment of chronic pain and emotional disorders. However, The mechanism by which EA mediates its analgesic and emotion-alleviating effects via the IL-BLA circuit remains uncertain. Here, we used chemogenetic manipulation combined with behavioral tests to detect pain induced anxiety-like and depression-like behaviors. We observed that activation of the IL-BLA circuit by chemogenetic activation induced depression-like behavior of mice. Additionally, we discovered that chemogenetic activation of the IL-BLA circuit successfully prevented the beneficial effects of EA on depression-like behavior brought on by chronic pain in mice with spared nerve injury (SNI). We discovered that SNI-induced depression-like behavior could be mitigated by inhibiting the circuit, and EA had a comparable depressive-relieving effect. Furthermore, the IL-BLA circuit's activation or inhibition had no effect on the anxiety-like feelings brought on by SNI. Overall, our findings identify a specific neural circuit that selectively regulates pain-induced depression-like emotions, without affecting pain-induced anxiety-like emotions. This discovery offers a precise target for future treatments of comorbid pain and depression and provides a plausible explanation for the efficacy of EA in treating depression-like emotions associated with chronic pain.
The study is as a cross-sectional, prospective, observational. After institutional review board approval and informed written consent, all patients aged ≥ 18 years undergoing spinal anesthesia in the Izmir Bozyaka Training and Research Hospital Operating Room will be included in the study. The specialist and assistant physician in charge of spinal anesthesia management of patients will undertake their own routine anesthesia management and the researcher will not be involved in any way. Patients who underwent combined spinal-epidural anesthesia and patients without consent were excluded. The primary aim of the study was to determine the rate of unsuccessful spinal anesthesia (total failure and partial failure) and to determine the factors that may be associated with these. Total failure was described as failure of localization of subarachnoid space with lumbar puncture; no motor and / or sensory block occurring within 10 minutes after the injection of local anesthetic into the subarachnoid space; repeated spinal anesthesia or general anesthesia. Partial failure was described as the need for anesthetic agents such as ketamine, propofol or opioid for the intraoperative pain relief, except for the use of midazolam and fentanyl in order to increase the patient's comfort.The secondary aim of the study was to determine the first attempt success and related factors. The first attempt success was described as identification or subarachnoid space at the first attempt.

Parameters will be recorded by Anesthesia Specialist, Anesthesia Assistant or Anesthesia Technician. At the end of the case, the registration form will be left at the designated place in the Anesthesia Clinic room.
Health controversies involve complex exchanges of disagreements over health and medicine. They unfold differently in different parts of the world, and they often extend over long periods of time. In contemporary argumentation theory, proposals have recently been emerging for "disagreement management at large scale" and for an explicit focus on design of disagreement management methods. Lewiński and Aakhus characterize large-scale disagreement as polylogic: formed of complex networks of players holding contrasting positions that are attacked and defended in multiple places. Large-scale disagreements such as health controversies are important sites for emergence of new disagreement management methods, including new ways of arriving at conclusions about questions of fact (affecting positions) and new formats for coming to decisions about questions of policy (affecting places). The controversy over myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS), spanning a period of very rapid change in reasoning about health, has been deeply entangled with the design of new institutional places for managing disagreements about health. It serves well to illustrate both the large, multi-scale structure of health controversies and the importance of long-term disagreement management strategies.
The regulation of leaf senescence and disease resistance plays a crucial role in determining rice grain yield and quality, which are important to meet the ever-increasing food demands of the world. Here, we identified an atypical Dof transcriptional factor OsDes1 that contributes to the stay-green phenotype, grain yield, and disease resistance in rice. The expression level of OsDes1 is positively associated with stay-green in natural variations of japonica rice, suggesting that OsDes1 would be alternatively used in breeding programs. Mechanistically, OsDes1 targets the promoter of the Rieske FeS protein gene OsPetC to activate its expression and interacts with OsPetC to protect against its degradation, thus promoting stay-green and ultimately improving the grain yield. OsDes1 also binds to the promoter region of defense-related genes, such as OsPR1b, and activates their expression, leading to enhanced disease resistance. These findings offer a potential strategy for breeding rice to enhance grain yield and disease resistance.
OBJECTIVE: The aim of this study was to investigate sex-related differences in the clinical characteristics and hospital outcomes of patients undergoing surgery for acute type A aortic dissection (AAAD).
METHODS: This study was a retrospective study. Patients who underwent surgery for AAAD at the Department of Cardiac Surgery, Fujian Medical University Union Hospital, from January 2014 to March 2023 were consecutively included. Data was extracted from electronic medical records. The primary outcome measure was in-hospital mortality, and secondary outcome measures included new-onset postoperative arrhythmia (POA), acute kidney injury (AKI), hepatic dysfunction, neurological complications, gastrointestinal hemorrhage, ICU length of stay, and hospital length of stay. Patients were divided into two groups based on sex, and data analysis was performed using SPSS 25.0 software.
RESULTS: A total of 1137 subjects were included, with 863 males (75.9%) and 274 females (24.1%). There were statistically significant differences in age and BMI between the two groups (P < 0.05). There was no statistically significant difference in the incidence of pain at the onset between the two groups, but chest tightness in females was higher than in males (22.6% vs. 13.8%). Regarding primary outcomes, the in-hospital mortality rate was 11.1% for males and 10.6% for females (P = 0.803). There were no statistically significant differences between the groups in ICU days, length of hospitalization, neurological complications, or liver dysfunction (P > 0.05). The rate of POA in females was 4.7%, higher than in males (2.2%), but AKI and gastrointestinal hemorrhage were both higher in males than in females (P < 0.05). Multivariate analysis showed that age, white blood cell (WBC) counts, lactic acid, operation duration and prolonged mechanical ventilation (PMV) increased the risk of in-hospital mortality in male patients. Hypertension, WBC counts, lactic acid, and PMV increased the risk of in-hospital mortality in female patients.
CONCLUSION: Despite significant baseline characteristic differences between male and female AAAD patients, there were no significant differences in onset symptoms. The in-hospital mortality rates were similar between male and female patients, but the risk factors for in-hospital mortality differed.
Recently developed new oral anticoagulants (OAC) overcome some of the limitations of established therapy with vitamin K antagonists (VKA) and low molecular weight heparin (LMWH) for treatment of acute venous thromboembolism (VTE), due to ease of administration and more predictable pharmacokinetic properties. Many clinical questions about the new OAC remain unanswered because there have not been direct head-to-head comparison trials. For example, although studies have shown that rivaroxaban and apixaban are at least as effective and safe as LMWH and VKA, meta-analyses suggest that apixaban may be associated with lower bleeding risk. Concerns about the potential impact of medication non-adherence have been raised. Compliance with twice daily medications (e.g. apixaban) is often worse than once daily medications (e.g. rivaroxaban). Both of these medications are approved by Health Canada for treatment of VTE yet there is genuine uncertainty about which of the two direct OAC confer the best risk-to-benefit ratio.This is a multi-centre, prospective randomized open blinded end-point (PROBE) trial assessing clinical feasibility for a larger multi-centered trial comparing bleeding outcomes using apixaban vs. rivaroxaban for treatment of acute VTE. The primary objective of the study is to determine if it is feasible to conduct a large randomized multicenter trial comparing apixaban vs. rivaroxaban for the treatment of acute VTE. The secondary objectives are to assess safety and superiority of apixaban vs rivaroxaban.
Neurodegenerative disorders have a pathophysiology that heavily involves neuroinflammation. In this study, we used lipopolysaccharide (LPS) to create a model of cognitive impairment by inducing systemic and neuroinflammation in experimental animals. LPS was injected intraperitoneally at a dose of 0.5 mg/kg during the last seven days of the study. Adalimumab (ADA), a TNF-α inhibitor, was injected at a dose of 10 mg/kg a total of 3 times throughout the study. On the last two days of the experiment, 50 mg/kg of curcumin was administered orally as a positive control group. Open field (OF) and elevated plus maze tests (EPM) were used to measure anxiety-like behaviors. The tail suspension test (TST) was used to measure depression-like behaviors, while the novel object recognition test (NOR) was used to measure learning and memory activities. Blood and hippocampal TNF α and nitric oxide (NO) levels, hippocampal BDNF, CREB, and ACh levels, and AChE activity were measured by ELISA. LPS increased anxiety and depression-like behaviors while decreasing the activity of the learning-memory system. LPS exerted this effect by causing systemic and neuroinflammation, cholinergic dysfunction, and impaired BDNF release. ADA controlled LPS-induced behavioral changes and improved biochemical markers. ADA prevented cognitive impairment induced by LPS by inhibiting inflammation and regulating the release of BDNF and the cholinergic pathway.
