Background: Macrophages play an important role in the symptoms and structural progression of periodontitis, and are receiving increasing attention. In recent years, research has shown significant progress in macrophage associated periodontitis. However, there is still lack of comprehensive and methodical bibliometric analysis in this domain. Therefore, this research aims to describe the state of the research and current research hotspots of macrophage associated periodontitis from the perspective of bibliometrics.

Methods: This study collected and screened a total of 1424 articles on macrophage associated periodontitis retrieved between 2004 and 2023 from Web of Science Core Collection database. Use Citespace (6.1. R6), Bibliometrix-R (4.1.3), VOSviewer (1.6.19), and Graphpad Prism8 software to analyze and plot countries/regions, institutions, journals, authors, literature, and keywords to explore the research hotspots and development trends of macrophage associated periodontitis.

Result: After analysis, the amount of macrophage associated periodontitis publications has been rising consistently over time, with China having the most publications (29.32%). 3 countries accounted for 65.57% of the total publications: the United States, China, and Japan, occupying a dominant position in this research field. China publications have the fastest growth rate and played a driving role. The most productive institution is the Sichuan University in China. Journal of Periodontal Research is highly popular in the field of macrophage associated periodontitis, with the highest number of publications. Grenier, Daniel is the most prolific author. Inflammation and Bone Loss in Periodontal Disease are the most cited literature. "Biological pathogenic factors," "immune regulation," "mechanism research," "susceptibility factor research," "pathological processes and molecular correlation," "pathological characteristics," "inflammatory response" are the main keyword groups in this field.

Conclusion: This study systematically analyzes and describes the development process, direction, and hotspots of macrophage associated periodontitis using bibliometric methods, providing a reference for future researchers who continue to study macrophage associated periodontitis.

Rationale: Small-cell undifferentiated carcinoma (SmCC), as an aggressive malignancy, are most commonly arising in lung. Extrapulmonary SmCC is rare. It was reported that SmCC accounts for only 0.1% to 0.2% of colorectal cancers. Currently, no standard treatment regimen is recommended. Here, we presented a case of SmCC from rectum. The patient achieved pathological complete response (pCR) after surgery, which makes us feel gratified, and we are also eager to share this successful case with more peers to provide more references for clinical decision-making.

Patient concerns: A 32-year-old male patient presented himself to our outpatient clinic with defecation difficulty for more than 1 month in November 2021.

Diagnoses: Colonoscopy revealed a rectal mass 4 cm from the anal margin. Pelvic magnetic resonance imaging revealed a mass in the rectal wall, consistent with the appearance of rectal carcinoma. Cancer cell was found after several biopsies and the immunohistochemistry indicated rectal SmCC.

Interventions: Considering that the patient is very young and the malignancy of SmCC is very high, our treatment plan is also very cautious. Many literatures were also searched, but the literature on rectal SmCC is few and the prognosis is poor. Subsequently, we combined the treatment principles of rectal cancer and small cell lung cancer to develop an individualized treatment plan for patients. The patient received neoadjuvant chemoradiotherapy (nCRT) (short-course radiotherapy: 25 Gy/5 fractions, chemotherapy: etoposide + nedaplatin) combined with immune checkpoint inhibitors (ICIs) (tislelizumab). Then, the patient received laparoscopic radical transabdominal resection of rectal carcinoma with a temporary stoma on June 27, 2022.

Outcomes: Postoperative pathology showed that there was chronic inflammation in the rectal mucosa without residual cancer, which meant that the patient achieved pCR after nCRT combined with ICIs. On August 15, 2024, the patient returned to our hospital for review, and no signs of recurrence and metastasis were found. By the time this article is submitted, the patient has survived for more than 35 months.

Lessons: This is the first to be reported in a rectal SmCC patient who achieved pCR after nCRT combined with ICIs, which may provide supporting data for using this treatment option for rectal SmCC.

The relationship between the alkaline phosphatase-to-albumin ratio (APAR) and mortality remains unclear. This research looked into the association between APAR levels and cause-specific mortality in US adults. A cohort of 7561 participants from National Health and Nutrition Examination Survey (2005-2016) was analyzed, with mortality outcomes collected from National Death Index records. Cox proportional hazards models and restricted cubic spline (RCS) analysis were utilized to determine hazard ratio (HR) and reveal the nonlinear relationship between APAR levels and mortality. Inflection points were calculated using a recursive algorithm. Followed for an average 99.41 months, a total of 1048 deaths occurred, including 200 cancer deaths and 348 cardiovascular disease-related deaths. Following multivariate adjustment, significant associations were observed between APAR levels and increased all-cause (HR 1.50, 95% CI 1.28-1.75, P < .001) and cardiovascular disease (HR 1.39, 95% CI 1.06-1.82, P = .018) mortality. Furthermore, nonlinear correlations between APAR levels and all-cause and cancer mortality were revealed, characterized by an L-shaped pattern, with mortality rates stabilizing at 1.289 and 2.167, respectively. Participants with APAR levels above the inflection point exhibited a 29.2% increase in all-cause mortality risk per unit increase in APAR levels (HR 1.292, 95% CI 1.217-1.372, P < .001), and a 38.3% increase in cancer mortality risk (HR 1.383, 95% CI 1.199-1.596, P < .001). This study demonstrated nonlinear associations between APAR levels and all-cause and cancer mortality. Thresholds of 1.289 and 2.167 might serve as potential targets for APAR to reduce all-cause and cancer mortality, respectively. Our findings suggest that APAR can be a valuable prognostic tool for clinical mortality risk assessments, helping to identify individuals at higher risk. Nevertheless, these findings necessitate validation through large-scale clinical trials for further substantiation.

Recent studies have demonstrated a correlation between salt intake (SI) and various diseases. However, it remains uncertain whether the relationship between SI (including salt added to food and sodium levels in urine) and benign osteoarthritis is causal. To investigate this, we conducted a 2-sample Mendelian randomization (MR) analysis to estimate the causal impact of SI on osteoarthritis (OA). A genome-wide association study of salt added to food and sodium in urine was used as the exposure, while hip osteoarthritis, knee osteoarthritis, and rheumatoid arthritis were defined as the outcomes. Inverse variance weighting (IVW) was used to calculate causal estimates, and sensitivity analyses were performed using methods including weighted mode, weighted median, MR-Egger, and Bayesian weighted MR. All statistical analyses were conducted using R software. Our results, primarily based on the IVW method, support the existence of a causal relationship between salt added to food and knee osteoarthritis (KOA). Specifically, salt added to food was associated with a decreased risk of KOA (OR = 1.248, P = .024, 95% CI: 1.030-1.512). This study is the first MR investigation exploring the causal relationship between salt added to food and KOA, potentially providing new insights and a theoretical basis for the prevention and treatment of KOA in the future.

Background: The aim of this study was to retrospectively investigate the effect of Crinone vaginal gel on pregnancy outcomes in women undergoing natural cycle (NC) frozen embryo transfer (FET) and to obtain the most suitable population for its routine application.

Methods: The 1613 women who underwent FET in the NC regimen [including the controlled ovulation stimulation protocol for the natural cycle, or the controlled ovulation stimulation protocol for the natural cycle (NC-COS)] from 2017 to 2021 were included. All patients were divided into 2 groups including Control group and Crinone group, which administered with or without Crinone vaginal gel. The key clinical information and between the 2 groups was recorded in detail.

Results: The results indicated that there were no statistical differences in blood β human chorionic gonadotropin (HCG) positive rate, clinical pregnancy, live birth, abortion (spontaneous and induced) and stillbirth between Control group and Crinone group. Moreover, Crinone could prevent spontaneous abortion. The spontaneous abortion rate in the Crinone group was 5.93% while this in control group was 8.32%. In the cohort exposed to Femoston, the preventive result was more significant (0/32 vs 5/15, P = .001). Furthermore, Crinone exhibited a significant protective effect on spontaneous abortion in 1520 patients who received no human menopausal gonadotropin (HMG) treatment.

Conclusion: This study demonstrated that the Crinone could protect women against spontaneous abortion, especially in patients who do not need HMG or in combination with Femoston.

Background: The diagnosis of renal ischemia and reperfusion injury (RIRI) is crucial for renal transplant recipients. RNA-binding proteins (RBPs) may have an impact on disease development. Therefore, this study explored the biomarkers associated with RBPs in RIRI.

Methods: The RIRI related datasets, GSE37838 and GSE43974, and 3964 RBPs were employed in this research. The differential expression analysis was implemented for RIRI and control to gain differentially expressed genes in GSE37838. Then, differentially expressed genes were overlapped with RBPs to acquire intersection genes. Further, the machine learning, diagnostic analysis, and expression validation were executed to filtered biomarkers for RIRI. Additionally, pathway enrichment, molecular networks, and drug prediction were proceed.

Results: The area under the curve values of NR4A2 and NR4A3 were >0.7, as well as the expression trend was consistent in both datasets, and all of them were remarkably highly expressed in RIRI. Therefore, they were considered as biomarkers of RIRI. Enrichment analyses revealed that they were both associated with neuroactive ligand-receptor interactions, among others. Further, the lncRNA-miRNA-mRNA and transcription factors (TF)-mRNA network was constructed, revealing that they were all regulated by noncoding RNAs and TF, such as SNHG5-hsa-mir-10b-5p-NR4A3, CREB1, TFAP2A, etc. In addition, a large number of biomarker-related drugs were predicted, among which cadmium acetate, potassium chromate (VI), etc were associated with NR4A2 and NR4A3.

Conclusion: In this study, we identified biomarkers associated with RBPs in RIRI, explored their associated pathways and drugs, which provided new insights into the clinical diagnosis and treatment of RIRI.

Background: Breast cancer remains a leading cause of cancer-related mortality worldwide. Patient self-management plays a pivotal role in enhancing outcomes and quality of life for individuals affected by this disease. This study employed bibliometric and visual analysis techniques utilizing CiteSpace to elucidate the current status and research hotspots in breast cancer patient self-management from January 1, 2005, to August 31, 2023.

Methods: A comprehensive search was conducted in the Web of Science Core Collection (WoSCC). The retrieved literature was subjected to visualization and analysis using CiteSpace, focusing on publication timeline, article count, geographical distribution, institutional affiliations, journal sources, reference co-citation networks, and keyword analysis.

Results: The analysis encompassed 1413 English-language documents. The United States emerged as the most prolific contributor, while the University of Toronto demonstrated the highest institutional output. The two-map overlay revealed prominent citation paths, indicating strong interconnections between publications in "Medicine, Medicine, Clinical" and "Health, Nursing, Medicine," as well as "Psychology, Education, Health" and "Health, Nursing, Medicine." The most frequently co-cited reference was "Self-Management: Enabling and Empowering Patients Living with Cancer as a Chronic Illness." High-frequency keywords identified included quality of life, chronic disease, self-management, patient education, randomized controlled trials, education, and intervention. These keywords formed 11 distinct clusters related to intervention content, methodologies, outcome indicators, and emerging research trends. Keyword burst analysis predicted future research hotspots focusing on patient needs, psychological distress, Internet technology, and mobile applications.

Conclusions: Research in breast cancer self-management is experiencing significant growth. Enhanced collaboration between countries, regions, and institutions is imperative. Further investigation is warranted, particularly in the domains of "quality of life," "patient education," and "mobile health." These findings provide valuable insights to guide future research directions in this critical field.

Rationale: Abdominal cocoon is an uncommon abdominal disease. Intestinal rupture complicated with intestinal fistula rarely occurs in patients with abdominal cocoon.

Patient concerns: A 51-year-old man was referred to hospital, with a 4-hour history of abdominal injuries caused by traffic accident. Intraoperatively, the small intestine in the abdominal cavity was surrounded by dense, tough, grayish-white fibrous tissue. There were the rupture of 2 sites in the ileum. The ileum was anastomosed side-to-side using a cutting and closing device. The patient was postoperatively transferred to the intensive care unit and received ventilator-assisted breathing, along with anti-infection and supportive treatments. On the 10th day after surgery, grass green turbid fluid of approximately 150 mL was extracted from the abdominal drainage tube. The secondary laparotomy was performed on the 12th day post-surgery, revealing a 1.5 cm diameter fistula at the end of the ileum.

Intervention and outcomes: Nursing strategies included ensuring optimal mechanical ventilation for oxygenation, utilizing Li's double cannula for continuous abdominal irrigation and negative pressure drainage to prevent abdominal abscess formation, emphasizing the importance of enteral nutrition, implementing direct suture treatment to manage retrograde infection and expedite stoma healing, and employing Li's double cannula and vacuum-assisted closure technique to promote incision healing. After 48 days secondary post-surgery, the incision was fully healed, and the patient was discharged home with the stoma bag. Five months later, he was readmitted to the hospital, and the stoma was reversed.

Lessons: Intestinal fistula poses a remarkable challenge after abdominal cocoon surgery, typically manifesting 4 to 5 days postoperatively. However, in this case, it occurred on the 10th day, highlighting the critical role of vigilant monitoring of drainage fluid color and volume in postoperative care. Navigating the complex management of intestinal rupture in abdominal cocoon necessitates a more efficacious approach, highlighting the importance of accumulating comprehensive nursing expertise through such cases.

Vitamin D deficiency has been proven to be associated with dyslipidemia. Additionally, the synthesis of vitamin D depends on cytochrome P450 2R1 (CYP2R1). However, the relationship between CYP2R1 polymorphisms and lipid metabolism has shown inconsistent results. A case-control study was conducted in a Han Chinese population, including 92 septic patients and 92 polytrauma patients. Based on serum lipid levels, 28 septic patients were further divided into a hyperlipidemia group, while 64 were placed in the control group; similarly, 34 polytrauma patients were categorized into a hyperlipidemia group and 58 into the control group. Genotyping of CYP2R1-rs10741657 was performed and serum lipid levels were measured. The Genotype-Tissue Expression project was used to assess expression quantitative trait loci for CYP2R1 mRNA expression and rs10741657. The genetic analyses revealed that the G-allele of CYP2R1-rs10741657 was significantly associated with an increased risk of hyperlipidemia in both sepsis (OR = 2.333, 95% CI: 1.227-4.436, P = .010) and polytrauma groups (OR = 4.000, 95% CI: 2.048-7.811, P < .001). Further analysis indicated that the rs10741657 mutation was mainly linked to higher serum high-density lipoprotein cholesterol levels in controls (P < .05). In functional analysis of rs10741657, the mutation was found to be associated with high CYP2R1 mRNA expression in whole blood from expression quantitative trait loci data (P = 3.53 × 10-9). In conclusion, the G-allele of CYP2R1-rs10741657 could elevate high-density lipoprotein cholesterol levels and protect against sepsis development.

Sepsis triggers severe inflammatory responses leading to organ dysfunction and demands early diagnostic and therapeutic intervention. This study identifies differentially expressed genes (DEGs) in sepsis patients using the Gene Expression Omnibus database to find potential diagnostic and therapeutic markers. We analyzed the dataset GSE123731 via GEO2R to detect DEGs, constructed protein-protein interaction networks, and performed transcription factor analyses using Cytoscape. Gene Ontology and Kyoto Encyclopedia of Genes and Genomes pathway analyses were conducted using R and FunRich software. Key genes were validated by Quantitative Reverse Transcription Polymerase Chain and co-immunoprecipitation assays in granulocytes from sepsis patients. We identified 59 DEGs significantly involved in neutrophil degranulation and immune system activation. Cytokine signaling pathways were highlighted in Kyoto Encyclopedia of Genes and Genomes analysis. Co-immunoprecipitation assays confirmed interactions involving matrix metallopeptidase 8, matrix metallopeptidase 9, and arginase 1, supporting their roles as biomarkers. The identified DEGs and validated interactions reveal crucial molecular mechanisms in sepsis, offering new avenues for diagnostic and therapeutic strategies, potentially enhancing patient outcomes.
