BACKGROUND: Dislocation is a major complication of total hip arthroplasty (THA). The modular femoral neck system provides practical advantages by allowing adjustment of neck version and length in the presence of intraoperative instability. Anatomical studies have identified morphological differences in the hip joint between men and women. Despite sex-based differences in hip morphology, it remains unclear whether such differences affect neck selectivity in THA using a modular neck system and whether this approach achieves anatomical reconstruction, thereby reducing complications such as dislocation. This study aimed to investigate gender differences in neck selectivity in THA with the modular neck system and assess the clinical impact of the modular neck system.
METHODS: A total of 163 THAs using a modular neck system were included in this study. Data on the type of modular neck and intraoperative range of motion (ROM) were retrieved from patient records. Pre- and post-operative leg length differences (LLD) were examined as part of the radiographic assessment. Dislocation was investigated as a postoperative complication.
RESULTS: Neck selectivity did not significantly differ between men and women. The comparison of pre- and post-operative LLD revealed a tendency for varus necks to improve LLD more than version-controlled necks. Furthermore, no significant correlation was found between intraoperative ROM and neck selectivity, or postoperative dislocation and neck selectivity.
CONCLUSIONS: This study on THA with a modular neck system provided valuable insights into sex-based differences in neck selectivity and highlighted the potential benefits of the modular neck system in addressing LLD and preventing postoperative dislocation.
OBJECTIVE: This study revealed a core regulator and common upstream mechanisms for the multifaceted pathological processes of age-related macular degeneration (AMD) and provided proof-of-concept for this new therapeutic target.
METHODS: Comprehensive gene expression analysis was performed using RNA sequencing of eye cup from old mice as well as laser-induced choroidal neovascularization (CNV) mouse model. Through integrative analysis and protein-protein interaction (PPI) analysis, common pathways and key transcription factor was identified simultaneously engaged in age-related retinal degeneration and CNV, the two typical pathological process of AMD. Subsequently, the expression changes of Spi1, the key regulator, as well as the alternation of the downstream mechanisms were validated in both models through qRT-PCR, Elisa, flow cytometry and immunofluorescence. Further, we assessed the impact of Spi1 knockdown in vitro and in vivo using gene intervention vectors carried by adeno-associated virus or lentivirus to test its potential as a therapeutic target.
RESULTS: Compared to corresponding controls, we found 1,939 and 1,319 genes differentially expressed in eye cups of old and CNV mice respectively. The integrative analysis identified a total of 275 overlapping DEGs, of which 150 genes were co-upregulated. PPI analysis verified a central transcription factor, SPI1. The significant upregulation of Spi1 expression was then validated in both models, accompanied by macrophage polarization towards the M1 phenotype. Finally, SPI1 suppression significantly inhibited M1 polarization of BMDMs and attenuated neovascularization in CNV mice.
CONCLUSION: This study demonstrates that SPI1 exerts a pivotal role in AMD by regulation of macrophage polarization and innate immune response, offering promise as an innovative target for treating AMD.
Cancer development and therapy resistance are driven by chromosomal instability (CIN), which causes chromosome gains and losses (i.e., aneuploidy) and structural chromosomal alterations. Technical limitations and knowledge gaps have delayed therapeutic targeting of CIN and aneuploidy in cancers. However, our toolbox for creating and studying aneuploidy in cell models has greatly expanded recently. Moreover, accumulating evidence suggests that seven conventional antimitotic chemotherapeutic drugs achieve clinical response by inducing CIN instead of mitotic arrest, although additional anticancer activities may also contribute in vivo. In this review, we discuss these recent developments. We also highlight new discoveries, which together show that 25 chromosome arm aneuploidies (CAAs) may be targetable by 36 drugs across 14 types of cancer. Collectively, these advances offer many new opportunities to improve cancer treatment.
BACKGROUND: COPD has been found to be associated with frailty. However, longitudinal evidence for associations of COPD with frailty progression is inadequate. Furthermore, recent studies revealed a new phenotype of lung function impairment: preserved ratio impaired spirometry (PRISm) findings. Associations of PRISm findings and their transitions with frailty progression are unclear.
RESEARCH QUESTION: What are the associations of PRISm findings, transitions of PRISm findings, and COPD with frailty progression?
STUDY DESIGN AND METHODS: To analyze the associations of PRISm findings and COPD with frailty progression, 5,901 patients were included from the English Longitudinal Study of Ageing. Patients were classified into three lung function patterns of normal spirometry (NS) findings, PRISm findings, and COPD. Frailty progression was assessed by repeated measurements of the frailty index (FI) during follow-up. Among these 5,901 patients, 3,765 patients were included to analyze the associations of PRISm findings transitions with frailty progression. PRISm findings transitions were assessed based on the changes of lung function patterns after a 4-year interval. Linear mixed-effect models were used for statistical analyses.
RESULTS: The median follow-up periods were 9.5 years for the analyses of PRISm findings and COPD with frailty progression and 5.8 years for PRISm findings transitions with frailty progression. When compared with participants with NS findings, patients with PRISm findings and COPD demonstrated accelerated FI progression with additional annual increases of 0.301 (95% CI, 0.211-0.392; P < .001) and 0.172 (95% CI, 0.102-0.242; P < .001), respectively. Patients who transitioned from NS findings to PRISm findings also demonstrated accelerated FI progression when compared with those with stable NS findings (β = 0.242; 95% CI, 0.008-0.476; P = .042). However, no accelerated FI progression was found in patients with PRISm findings who transitioned to NS findings (β = 0.119; 95% CI, -0.181 to 0.418; P = .438).
INTERPRETATION: Our findings indicate that PRISm findings and COPD are associated with accelerated frailty progression. Further studies are needed to elucidate the causality of the association of PRISm findings and COPD with frailty.
Trimethylamine-N-oxide (TMAO) is a carbon-containing organic compound formed from dietary precursors including TMAO (high in fish), choline (high in eggs) and carnitine (high in beef). However, TMAO production is highly variable (Zhang AQ et al., 1999), appears to be influenced by genetics (Cashman JR et al., 2001) and gut microbiome (Wang Z et al., 2011; Koeth RA et al., 2013), and is linked to heart disease in cardiac patients (Wang Z et al., 2011) and colorectal cancer among post-menopausal women (Bae S et al., 2015). At present, very little is known about the metabolic fate of TMAO and how it is used within the human body (Bain MA et al., 2005). This study sought to (i) quantify the effects of eggs, beef and fish on TMAO biomarkers in plasma, muscle, urine and stool; (ii) examine the metabolic fate of supplemental TMAO labeled isotopically with deuterium; and (iii) determine whether TMAO production is a function of the gut microbiome.

To accomplish these objectives, a randomized, controlled cross-over study was conducted in healthy male participants (n=40). The study incorporated four arms comprised of study meals representing animal sources of TMAO (egg, beef and fish) along with a fruit control. The study meals were (i) 3 whole hard-boiled eggs; (ii) 6 oz beef (Philly-Gourmet Beef Patties); (iii) 6 oz fish (cod fillet); and (iv) 2 single-serve packages of Mott's natural applesauce. Each meal was served with one cup of water, administered in a single day and separated by a 1-week washout period. For the fruit control, 50 mg deuterium-labeled methyl-d9-TMAO (d9-TMAO; Cambridge Isotopes) was added to one cup of water for oral consumption to enable the tracing of the metabolic fate of TMAO, and to assess its bioavailability and clearance.

Baseline blood sample was obtained by a phlebotomist using a standard venipuncture procedure, and participants collected their baseline urine sample. They also turned in self-collected baseline 24 h urine and stool samples. Following the consumption of the study meal, serial blood samples were collected at 15, 30 min and 1, 2, 4 and 6 h, while urine samples were collected throughout the 6 h study period. At 4.5 h, participants were provided a fixed fruit snack (i.e., applesauce) and water. On the day that participants consumed the d9-TMAO tracer, participants collected their urine throughout the next 24 h and their stool at the next bowel movement. In addition, a subset of this group (n=6) were invited to undergo a muscle biopsy procedure 6 h after the fruit + d9-TMAO tracer consumption.
\[68Ga\]CBP8 is a novel gallium-68 labeled positron emission tomography (PET) probe that selectively binds collagen type I, which constitutes the majority of fibrotic tissue. In pre-clinical mouse models, \[68Ga\]CBP8 had the sensitivity to detect pulmonary fibrosis even at early stages and specificity for collagen uptake with low non-specific uptake in background tissues and organs. In preliminary studies in humans with idiopathic pulmonary fibrosis, patients tolerated \[68Ga\]CBP8 without adverse effects, and there was a strong correspondence between high collagen tracer signal and fibrotic lung regions established by chest computed tomography (CT) scan. \[68Ga\]CBP8 may be a valuable tool to detect and quantify collagen in the heart. The investigators propose to test \[68Ga\]CBP8 in a pilot study to image myocardial fibrosis in patients with cardiac amyloidosis.

Cardiac amyloidosis is characterized by myocardial interstitial infiltration by misfolded amyloid fibrils. Infiltration leads to increased myocardial stiffness and heart failure. In patients with cardiac amyloidosis, myocardial stiffness may also be caused by extracellular collagen deposition in the myocardium. Collagen deposition (i.e. myocardial fibrosis) results in adverse cardiac remodeling through similar mechanisms as amyloidosis and may potentiate heart failure in patients with cardiac amyloidosis. Myocardial fibrosis can be mitigated or prevented. In addition, therapies directed against amyloid fibrils also have differential response rates in cardiac amyloidosis patients with or without coexistent fibrosis. Magnetic resonance imaging (MRI) is an established method of measuring extracellular volume (ECV), a reliable way of quantifying myocardial fibrosis in conditions where the primary reason for ECV expansion is myocardial fibrosis. ECV may not be an optimal surrogate of myocardial fibrosis in patients with cardiac amyloidosis, where ECV is already quite expanded due to myocardial amyloid infiltration. Thus, a means of accurate, non-invasive quantitation of myocardial fibrosis has the potential to significantly improve cardiac amyloidosis care.

This pilot study is designed to understand whether myocardial fibrosis can be measured using a collagen 1 targeted radiotracer (\[68Ga\]CBP8). The investigators would like to study 15 patients with light-chain (AL) cardiac amyloidosis and 15 patients with transthyretin (ATTR) cardiac amyloidosis to understand differences in radiotracer uptake, if any. The investigators will also enroll 15 patients with recent myocardial infarction and 15 patients with hypertrophic cardiomyopathy as positive controls for fibrosis and will enroll 5 individuals without cardiovascular disease as negative controls.

The aim of this proposed research study is, using simultaneous PET/MRI imaging, to determine whether \[68Ga\]CBP8 uptake will accurately identify and quantify myocardial fibrosis in patients with cardiac amyloidosis, recent myocardial infarction, and hypertrophic cardiomyopathy. The aim of this study is also to correlate \[68Ga\]CBP8 PET uptake with standard MRI measures in patients with cardiac amyloidosis.
Pregnancy and birth represent a major crisis and stressful period in a woman's life. The quality of experiences during birth affects the mother's physical and emotional health, her desire to have another child, and her emotional relationship with the child (Vaziri et al., 2012). It is stated that there are relationships between increased maternal birth satisfaction and the quality of care and birth services provided (Jha et al., 2017). Lack of satisfaction can lead to postpartum depression, breastfeeding disorders, changes in the mother's attitude towards having another child in the future, and subsequent changes at birth with associated disorders (Sayed et al., 2018). The applicability of methods that can alleviate pain during the birth stages can turn birth into a positive and satisfying experience (Kordi et al., 2018). Among these methods, non-drug and supportive treatments can improve the mental and emotional aspects of birth by reducing the severity of pain and fear, reduce the frequency of elective caesarean sections, and increase the statistics of natural birth. Despite treatment measures, when a pregnant woman experiences pain and stress, the sympathetic nervous system is constantly stimulated, resulting in an increase in the secretion of catecholamines and therefore an increase in pulse rate and systolic blood pressure (Makvandi et al., 2013). The increase in catecholamines may reduce blood flow from the mother to the fetus, ultimately causing uterine contractions to be less effective and prolonging labor. Therefore, improving maternal and fetal outcomes is recommended to positively impact maternal satisfaction with birth (Zare et al., 2017).

Measures aimed at reducing pain and shortening the length of labor stages may increase maternal satisfaction with the birth experience ( Kordi et al., 2018 ). Maternal and fetal complications limit the use of pharmacological methods to facilitate birth; For this reason, more user-friendly, non-prescription, lower-cost and less complicated methods are preferred (Mirghafourvand et al., 2014). Although there are many techniques available today to make the birth experience enjoyable, it is still important to find more easily applicable methods (Siddiquee et al., 2016). One of the non-medical interventions to reduce sensitivity is the cognitive-behavioral approach; With this approach, the individual's attention is shifted from a painful stimulus to an external stimulus (Indovina et al., 2016). This non-pharmacological approach can be adopted to alleviate stress and lower cortisol concentrations in response to stress. Having a patient with pain watch a video can be used to "direct attention to a different direction", which is a part of nursing care in pain management (İnal and Canbulat, 2015). There are studies using different non-invasive methods to reduce pain during labor (Ebrahimian and Bilandi, 2021; Kazeminia et al., 2020). However, no randomized controlled study has been found in which comedy videos were watched for labor pain management and birth satisfaction. For this reason, it is planned to investigate the effect of comedy video on pain and birth satisfaction in this study.

A secure and easily feasible vascular access is crucial for oncology patients because of the therapeutic need. Although intravenous port has been utilized for 3 decades, catheter-related complication still remain and had to deal with. According to investigators clinical experience, investigators summarized a standard algorithm as a recommendation for intravenous sport implantation. The complication before and after standard algorithm was 20 % and 3.5 %, respectively. However, catheter related infection and malfunction still could not be avoided. If patient was identified with these 2 complications, re-intervention is needed and cancer-related therapy has to be postpone. Investigators deconstructed the port that removed from patients and identified there were structural weakness, old blood clot and fibrin deposits. Investigators consider the problem may be exist in maintenance. After thoroughly examination the maintenance protocol, investigators identified the problem and try to remodel the maintenance protocol. The Goal of this study was to testify the clinical value of standard maintenance protocol.
Positive effects of n-3 long chain polyunsaturated fatty acids (PUFAs), as provided by fatty fish intake, on cognitive functions are widely accepted, but so far there is no clear evidence from randomized intervention studies in children and young adults, although fish intake has been positively associated with cognitive functions in observational studies. The main aim of this study is to test the effect of diet on improvement in cognitive performance in kindergarden children aged 4-6 years. In the intervention study, children will be randomly allocated into two groups, one consuming prepared meals with herring or mackerel for four months, and one group consuming meals containing meat as a control group. The children (n=200) will consume the prepared meals three times a week. Cognitive performance of the children will be tested at study start and end using the the Wechsler Preschool and Primary Scale of Intelligence (WPPSI_III) and nine hole peg test. Children will be screened for mental health problems in the Strengths and Difficulties Questionnaire (SDQ), which is a global measure of children's mental health. Compliance will be monitored by documentation of study fish intake and measuring fatty acid status. For a more detailed investigation of effects of increased herring and mackerel intake, before and after intervention blood and urine will be collected for lipidomic analysis (metabolites), vitamin D and iodine determination and genotyping (fatty acid metabolism and inflammation).
All subjects to receive first 50mg/d Safinamide with an increase of target dose of 100mg/d after 14 days of taper period until end of treatment visit. In case of any intolerance the daily dose of 100mg might be decreased to 50mg/d. Patients permanently discontinuing treatment will enter a 7day taper phase before treatment discontinuation at a dose of 50mg/day. Subjects already taking 50mg/d may stop Safinamide immediately.
Disrupted sleep has been linked to suicidal thoughts and behavior. Less is known, however, about the underlying mechanisms of this relationship. A more nuanced understanding of the link between sleep and suicide may help inform treatment decisions and the development of prevention and intervention strategies. The present study examined daily average sleepiness as a moderator to the relation between same-day passive and active suicide ideation (SI). Fifty-nine young adults (mean age = 21.04; SD = 2.22) endorsing SI at least twice in the two weeks prior to baseline completed 3-5 daily surveys of sleepiness and SI over 2 weeks as part of a broader study. Across several indicators of sleepiness (desire to stay awake, desire to fall asleep), passive SI (desire to die, desire to live), and active SI (occurrence, intensity, duration, and controllability), the overall findings demonstrated that daily average sleepiness magnified the relation between same-day passive SI and active SI severity. These findings indicate that being sleepier than usual may increase the likelihood that passive SI transitions to active SI. Future research is needed to test the causal influence of sleepiness on this transition.
Gastric cancer (GC) is the fifth most prevalent malignancy worldwide, characterized by poor prognosis. Apoptosis is interacted with hypoxia in tumorigenesis. This study attempted to delineate potential value of apoptosis and hypoxia-related genes (AHRGs) in prognosis of gastric cancer. Differential expression analysis was performed on GC transcriptomic data from TCGA. Apoptosis-related genes (ARGs) and hypoxia-related genes (HRGs) were obtained from MSigDB, followed by intersecting them with differentially expressed genes (DEGs) in GC. A prognostic model was constructed using univariate, LASSO, and multivariate regression analyses. The model was validated using a Gene Expression Omnibus dataset. DEGs between risk groups were subjected to enrichment analysis. A nomogram was plotted by incorporating clinical information. Non-negative matrix factorization based on core prognostic genes from the multifactorial model was employed to cluster tumor samples. The subsequent analyses involved immunophenoscore, immune landscape, Tumor Immune Dysfunction and Exclusion (TIDE) score, and chemosensitivity for distinct subtypes. A prognostic model based on AHRGs was established, and its predictive capability was verified in external cohorts. Riskscore was determined as an independent prognostic factor, and it was used, combined with other clinical features, to plot a prognostic nomogram. Patients were clustered into cluster1 and cluster2 based on prognostic model genes. Cluster2 showed poorer prognosis and IPS scores, higher immune cell infiltration, immune function and TIDE scores than cluster1. Distinct therapeutic potential for various chemotherapeutic agents was observed between the two clusters. The developed AHRG scoring introduced a novel and effective avenue for predicting GC prognosis and identifying potential targets for further investigation.
