Background:

Frailty has been identified as a risk factor for adverse outcomes in older adults with diabetes. This study aimed to investigate the impact of frailty on the prognosis of older adults with diabetes through a systematic review and meta-analysis, with the goal of offering insights for clinical decision-making.

Methods:

PubMed, Web of Science, Embase, Cochrane were systematically searched from inception to September 10th, 2023. Reviewers independently selected studies, extracted data and evaluated the quality of studies. Stata 15.1 Software was used to perform the meta-analysis. The primary outcomes of this study were mortality, hospitalization and disability, and the secondary outcomes were diabetes complications (including nephropathy, microvascular complications, macroangiopathy, cardiovascular events, hypoglycemia) and urolithiasis.

Results:

A total of 14 studies were included in this study, with low risk of bias and moderate to good quality. The results showed that frailty increased the risk of mortality (HR 1.91, 95% CI 1.55–2.35, P < .001), hospitalization (HR 2.19, 95% CI 1.53–3.13, P < .001), and disability in older adults with diabetes (HR 3.84, 95% CI 2.35–6.28, P < .001). In addition, frailty was associated with diabetes complications (including nephropathy, microvascular complications, macroangiopathy, cardiovascular events, hypoglycemia), urolithiasis.

Conclusions:

Frailty is an important predictor of adverse outcomes, such as mortality, hospitalization, and disability in older adults with diabetes. Accurate assessment of the frailty in older adults with diabetes can help improve the adverse outcomes of patients.

Published: June 2024

Species of the genus Codonopsis (Campanulaceae) have a long history of application, acclaimed for its edible and therapeutic attributes. Scholarly inquiries into Codonopsis span botany, phytochemistry, quality assurance, pharmacodynamics, and toxicity, revealing a rich and comprehensive body of knowledge. This study synthesizes information from esteemed scientific databases like SciFinder, PubMed, China National Knowledge Infrastructure, and Chinese herbal classics to create a thorough scientific conceptual and theoretical framework for Codonopsis research. In this article, the phytochemical composition includes saccharides, polyacetylenes, polyenes, flavonoids, alkaloids, lignans, terpenoids, and organic acids was summarized. To date, over 350 monomeric compounds have been isolated and identified from Codonopsis, with recent studies primarily focusing on polysaccharides, aromatic derivatives, lignans, and polyacetylenes. Codonopsis exhibits broad pharmacological activities across various systems, including immune, blood, cardiovascular, central nervous, and digestive systems, with no significant toxicity or adverse effects reported. The existing research, focusing on various extracts and active parts without identifying specific active molecules, complicates the understanding of the mechanisms of action. There is an urgent need to advance research on the chemical composition and pharmacological effects to fully elucidate its pharmacodynamic properties and the basis of its material composition. Such efforts are crucial for the rational development, utilization, and clinical application of this herb.

Few studies have examined the risk factors associated with the type of acute respiratory failure (ARF) in patients with acute exacerbation of chronic obstructive pulmonary disease (COPD). This study evaluated the clinical characteristics and prognosis of patients hospitalized for acute exacerbation of COPD based on the type of ARF. The medical charts of hospitalized patients with acute exacerbation of COPD between 2016 and 2021 were retrospectively reviewed. We classified ARF into 2 types: type 1 ARF with PaO2 < 60 mm Hg in room air or a ratio of arterial partial pressure to fractional inspired oxygen < 300, and type 2 ARF with PaCO2 > 45 mm Hg and arterial pH < 7.35. A total of 435 patients were enrolled in study, including 170 participants without ARF, 165 with type 1 ARF, and 100 with type 2 ARF. Compared with the non-ARF group, the frequency of high-flow nasal cannula, noninvasive ventilation, intensive care unit admissions, and in-hospital deaths was higher in the ARF group compared with the non-ARF group. The ARF group had higher 1-year mortality group (hazard ratio [HR], 2.809; 95% confidence interval [CI], 1.099–7.180; P = .031) and readmission within 1-year rates (HR, 1.561; 95% CI, 1.061–2.295; P = .024) than the non-ARF group. The type 1 ARF group had a higher risk of 1-year mortality (HR, 3.022; 95% CI, 1.041–8.774; P = .042) and hospital readmission within 1-year (HR, 2.053; 95% CI, 1.230–3.428; P = .006) compared with the non-ARF group. There was no difference in mortality and readmission rates between the type 1 and type 2 ARF groups. In conclusion, patients with type 1 ARF rather than type 2 ARF had higher mortality and readmission rates than those without ARF. The prognoses of patients with type 1 and type 2 ARF were similar.

Authors: Wang Jiani , Li Jian , Ji Yong
Published: June 2024

Gut microbiota, a special group of microbiotas in the human body, contributes to health in a way that can’t be ignored. In recent years, Mendelian randomization, which is a widely used and successful method of analyzing causality, has been investigated for the relationship between the gut microbiota and related diseases. Unfortunately, there seems to be a shortage of systematic bibliometric analysis in this field. Therefore, this study aims to investigate the research progress of Mendelian randomization for gut microbiota through comprehensive bibliometric analysis. In this study, publications about Mendelian randomization for gut microbiota were gathered from 2013 to 2023, utilizing the Web of Science Core Collection as our literature source database. The search strategies were as follows: TS = (intestinal flora OR gut flora OR intestinal microflora OR gut microflora OR intestinal microbiota OR gut microbiota OR bowel microbiota OR bowel flora OR gut bacteria OR intestinal tract bacteria OR bowel bacteria OR gut metabolites OR gut microbiota) and TS = (Mendelian randomization). VOSviewer (version 1.6.18), CiteSpace (version 6.1.R1), Microsoft Excel 2021, and Scimago Graphica were employed for bibliometric and visualization analysis. According to research, from January 2013 to August 2023, 154 publications on Mendelian randomization for gut microbiota were written by 1053 authors hailing from 332 institutions across 31 countries and published in 86 journals. China had the highest number of publications, with 109. Frontiers in Microbiology is the most prolific journal, and Lei Zhang has published the highest number of significant articles. The most popular keywords were “Mendelian randomization,” “gut microbiota,” “instruments,” “association,” “causality,” “gut microbiome,” “risk,” “bias,” “genome-wide association,” and “causal relationship.” Moreover, the current research hotspots in this field focus on utilizing a 2-sample Mendelian randomization to investigate the relationship between gut microbiota and associated disorders. This research systematically reveals a comprehensive overview of the literature that has been published over the last 10 years about Mendelian randomization for gut microbiota. Moreover, the knowledge of key information in the field from a bibliometric perspective may greatly facilitate future research in the field.

Published: June 2024

Appendicitis is an inflammation caused by obstruction of the appendiceal lumen or termination of blood supply leading to appendiceal necrosis followed by secondary bacterial infection. The relationship between TYROBP gene and the nursing of appendicitis remains unclear. The appendicitis dataset GSE9579 profile was downloaded from the gene expression omnibus database generated from GPL571. Differentially expressed genes were screened, followed by weighted gene co-expression network analysis, functional enrichment analysis, gene set enrichment analysis, construction and analysis of protein–protein interaction network, Comparative Toxicogenomics Database analysis, and immune infiltration analysis. Heatmaps of gene expression levels were plotted. A total of 1570 differentially expressed genes were identified. According to gene ontology analysis, they were mainly enriched in organic acid metabolic process, condensed chromosome kinetochore, oxidoreductase activity. In Kyoto Encyclopedia of Gene and Genome analysis, they mainly concentrated in metabolic pathways, P53 signaling pathway, PPAR signaling pathway. The soft threshold power in weighted gene co-expression network analysis was set to 12. Through the construction and analysis of protein–protein interaction network, 5 core genes (FCGR2A, IL1B, ITGAM, TLR2, TYROBP) were obtained. Heatmap of core gene expression levels revealed high expression of TYROBP in appendicitis samples. Comparative Toxicogenomics Database analysis found that core genes (FCGR2A, IL1B, ITGAM, TLR2, TYROBP) were closely related to abdominal pain, gastrointestinal dysfunction, fever, and inflammation occurrence. TYROBP gene is highly expressed in appendicitis, and higher expression of TYROBP gene indicates worse prognosis. TYROBP may serve as a molecular target for appendicitis and its nursing.
Effectiveness and safety of Chaihu-Shugan-San for treating depression based on clinical cases: An updated systematic review and meta-analysis
Authors: Zhang Xiaohang , Zhao Qiulong , Wang Yang , Mao Yaqing , Sun Yue , Bian Xiaokun
Published: June 2024

Background:

Chaihu-Shugan-San (CSS), a Traditional Chinese Medicine formula, has been widely used for treating depression since the Ming Dynasty, as recorded in Jingyue Quanshu, but its effectiveness and safety lack comprehensive and objective evaluation. Based on our meta-analysis, we aimed to adequately evaluate the efficacy and risk of CSS by considering the latest clinical literature.

Methods:

Multiple databases, including PubMed, Embase, Web of Science, SinoMed, China National Knowledge Infrastructure, Chongqing VIP, and Wanfang, were used to collect clinical data. The quality of the included clinical studies was assessed using the Cochrane Risk of Bias Tool, and the data were meta-analyzed using Review Manager 5.0 and Stata 17. The data were obtained from a genome-wide association study, and Mendelian randomization (MR) was performed using R Software 4.3.2 with the TwoSampleMR and MR Pleiotropy RESidual Sum and Outlier packages.

Results:

A total of 15 studies with 1034 patients and 6 antidepressant drugs were included in this work. Meta-analyses revealed that drug combinations of CSS and antidepressants significantly improved depressive symptoms (weighted mean difference = −4.21; 95% confidence interval [CI]: −5.62–−2.81), increased the effective rate (odds ratio [OR] = 3.82; 95% CI: 2.44–6.83), and reduced side effects (OR = −3.55; 95% CI: −5.66–−1.43) compared with antidepressant monotherapy. Additionally, compared with antidepressant monotherapy, CSS alone exhibited fewer side effects (95% CI:−9.25–−6.95). Like antidepressants, CSS also improved depressive symptoms (weighted mean difference = −0.05; 95% CI: −0.63–−0.52) and increased the effective rate (OR = 1.07; 95% CI: 0.52–2.20). Additionally, MR was used to evaluate the safety of traditional antidepressants, as there was a causal association between amitriptyline and body mass index.

Conclusion:

This analysis demonstrated that compared with traditional antidepressants, CSS combined with antidepressants was more effective and safer for treating depressed patients. MR showed that a causal relationship may exist between amitriptyline and body mass index. Therefore, clinicians should carefully consider the advantages and potential drawbacks of Traditional Chinese Medicine and classic drugs to serve patients better.

Authors: Zhou Jingjing , Zhou Lili
Published: June 2024

Diabetic foot (DF) ulcer is one of the common complications of diabetic patients, with high incidence and amputation rate, which seriously affects the quality of life and health of patients. Therefore, how to effectively prevent and treat DF ulcers and reduce amputation rate has become an urgent problem in the medical field. As a comprehensive nursing model for patients with DF ulcers, comprehensive nursing intervention is designed to improve the therapeutic effect and prognosis and reduce the rate of amputation. Convenient sampling method was used to select 360 patients with DF who received routine care for DF ulcers from July 2013 to July 2023 for retrospective cohort analysis. According to the existence of exposure factors (comprehensive nursing intervention), 180 cases were divided into observation group and comparison group. The basic demographic data, amputation rate, severity of foot ulcer, neuropathy and vascular disease, and blood glucose control were compared between the 2 groups. The data was analyzed using SPSS26.0. Harman single factor test was used to check whether there was common method bias in the study data. Descriptive analysis, Spearman rank correlation analysis and multiple linear regression analysis were used to analyze the current situation of amputation rate of DF patients and the influence of comprehensive nursing intervention on the amputation rate of DF patients. The amputation rate was 2.8% in the Observation group compared to 8.3% in the Comparison group. The amputation rate of the observation group was generally higher in the age group, and the amputation rate of the observation group was higher in the middle school education level and below and the economic status of <5000 yuan. The difference was statistically significant (P < .05). Age (odds ratio [OR] = 1.96; 95% confidence interval [CI]: 0.88–4.38), education level (OR = 1.30; 95% CI: 1.69–6.46), economic status (OR = 2.28; 95% CI: 1.69–10.85) was an independent risk factor for amputation rate (P < .05). Comprehensive nursing interventions have played a positive role in reducing the rate of amputation in patients with DF.

Published: June 2024

An observational study to discover the common conditions affecting the lumbosacral region that may affect lumbosacral position and tension. All the patients, underwent MRI exaamination (magnetic resonance imaging) in the supine position, were examined by the same consultant radiologist. The article was revised by the institutional ethical approval committee. The position of the nerve roots was observed, and the number of nerve roots was calculated anterior to a line passing between the mid-transvers process of L3(third lumbar vertebra). The number of nerve roots ahead of this line was calculated by the radiologist at the level of the right intervertebral foramen and at the left one. This procedure was applied to the normal group, and 5 common pathological diseases were repeated including single-level lumbar disc prolapse, multiple-disc prolapse, multiple bulge, spinal stenosis and spondylolisthesis (at the level of L45 (fourth to fifth lumbar vertebrae) or L5S1 (fifth lumbar to first sacral vertebrae) being outside the study area, i.e., L3). We noticed significant difference in the number of the nerve roots between the cases with herniated discs, spinal stenosis, and spondylolisthesis with the normal group and the significance was in ascending increment in significance being the highest in cases with spondylolisthesis, and even in the groups of other pathologies which are statistically not significant, we noticed that the significance is proportional to the severity of the disease being the least in single level cases (p 0.427), to be more significant on cases with multiple prolapses(p 0.319) to be more in cases with multiple bulges to start to be statistically significant in herniated, higher significance in cases with spinal stenosis to be the highest in cases with spondylolisthesis.
Identification of shared disease marker genes and underlying mechanisms between rheumatoid arthritis and Crohn disease through bioinformatics analysis
Authors: Peng Peifei , Shen Ying
Published: June 2024

As chronic autoimmune inflammatory diseases, rheumatoid arthritis (RA) and Crohn disease (CD) are closely associated and display a significant positive correlation. However, the underlying mechanisms and disease markers responsible for their cooccurrence remain unknown and have not been systematically studied. Therefore, this study aimed to identify key molecules and pathways commonly involved in both RA and CD through bioinformatic analysis of public sequencing databases. Datasets for RA and CD were downloaded from the GEO database. Overlapping genes were identified using weighted gene co-expression network analysis and differential analysis crossover, and enrichment analysis was conducted for these genes. Protein-protein interaction networks were then constructed using these overlapping genes to identify hub genes. Expression validation and receiver operating characteristic curve validation were performed for these hub genes using different datasets. Additionally, the immune cell correlation, single-cell expression cluster, and the immune cell expression cluster of the core gene were analyzed. Furthermore, upstream shared microRNAs (miRNA) were predicted and a miRNA-gene network was constructed. Finally, drug candidates were analyzed and predicted. These core genes were found to be positively correlated with multiple immune cells that are infiltrated by the disease. Analysis of gene expression clusters revealed that these genes were mostly associated with inflammatory and immune responses. The miRNA-genes network analysis suggested that hsa-miR-31-5p may play an important role in the common mechanism of RA and CD. Finally, tamibarotene, retinoic acid, and benzo[a]pyrene were identified as potential treatment options for patients with both RA and CD. This bioinformatics study has identified ITGB2, LCP2, and PLEK as key diagnostic genes in patients with both RA and CD. The study has further confirmed that inflammation and immune response play a central role in the development of both RA and CD. Interestingly, the study has highlighted hsa-miR-31-5p as a potential key player in the common mechanism of both diseases, representing a new direction in research and a potential therapeutic target. These shared genes, potential mechanisms, and regulatory networks offer new opportunities for further research and may provide hope for future treatment of patients with both RA and CD.

Published: June 2024

Background:

Neutrophil to lymphocyte ratio (NLR) has been considered a prognostic biomarker of mortality and other major cardiac events. This study investigates NLR’s efficacy in predicting in-hospital and long-term outcomes in patients with ST-segment elevated myocardial infarction (STEMI) undergoing percutaneous coronary intervention (PCI).

Methods:

Electronic databases (PUBMED, Cochrane CENTRAL, ERIC, Embase, Ovid, and Google Scholar) were searched till June 2022 to identify studies having STEMI patients who underwent PCI. Risk ratios and mean differences (MDs), along with their corresponding 95% confidence intervals (Cis) and standard deviations (SDs), were pooled using a random-effect model. This meta-analysis has been registered on Prospero (ID: CRD42022344072).

Results:

A total of 35 studies with 28,756 patients were included. Pooled estimates revealed an increased incidence of primary outcomes; in-hospital all-cause mortality (RR = 3.52; 95% CI = 2.93–4.24), long-term all-cause mortality (HR = 1.07; 95% CI = 1.00–1.14), (RR = 3.32; 95% CI = 2.57–4.30); in-hospital cardiovascular mortality (RR = 2.66; 95% CI = 2.04–3.48), long-term cardiovascular mortality (RR = 6.67; 95% CI = 4.06–10.95); in-hospital major adverse cardiovascular events (MACE) (RR = 1.31; 95% CI = 1.17–1.46), long-term MACE (RR = 2.92; 95% CI = 2.16–3.94); length of hospital stay (WMD = 0.60 days; 95% CI = 0.40–0.79) in patients with high NLR compared to those with a low NLR.

Conclusion:

NLR might be a valuable tool for prognostication (in-hospital) and stratification of patients with STEMI who underwent PCI.

Published: June 2024

Isolated popliteal artery occlusions are rare compared with femoropopliteal occlusive diseases. Although endovascular procedures have gained importance in treatment, conventional surgery remains the gold standard. In this study, we reviewed popliteal endarterectomy and patch plasty using a posterior approach. Fourteen patients who underwent surgery for isolated popliteal artery occlusions were retrospectively examined. Patients were assessed in terms of age, sex, and risk factors, such as accompanying diseases and smoking, surgical method and anesthesia, incision type, preoperative and postoperative pulse examination, ankle-brachial indices, patency, wound infection, postoperative complications, and the treatment applied. Twelve (85.7%) patients were male, and 2 (14.3%) were female. Limb ischemia was critical (ABI < 0.7) in 11 (78.5%) patients. The average duration of postoperative hospitalization was 8 ± 3.7 days on average, and the average length of follow-up was 17 ± 3.4 months. Thrombosis and complications requiring secondary intervention did not develop during the early postoperative period. While the patency rate in the first 6 months of follow-up was 100%, it was 92.8% in the 1st year and 85.7% in the 2nd year. Surgical treatment with the posterior approach in isolated popliteal artery lesions is preferred by vascular surgeons as a prioritized treatment method, with a sufficient recanalization rate and low perioperative morbidity and mortality rates. Furthermore, it is promising because it does not prevent below-knee femoropopliteal bypass, which is the subsequent stage of treatment. Moreover, the great saphenous vein was protected, and the acceptable early- and mid-term results were encouraging.

Authors: Bayraktar Necmi , Bayraktar Ümmü
Published: June 2024

Background:

Understanding the knowledge and attitudes of university students regarding organ transplantation and donation is crucial, as these students can significantly influence public opinion and behavior. This study aims to assess the knowledge and attitudes of North Cyprus University students towards organ transplantation and donation.

Methods:

A cross-sectional study was conducted with 400 students from Northern Cyprus University, divided into medical and social science faculties. A structured questionnaire was utilized to assess their knowledge and attitudes towards organ transplantation and donation. Descriptive statistics, Chi-square tests, and effect size calculations were employed for data analysis.

Results:

Among the 400 students, 27% demonstrated sufficient knowledge of organ transplantation, and 62.7% had positive views on organ donation. Willingness to donate was expressed by 37% as living donors and 64% as deceased donors. There were no significant differences in knowledge and attitudes between medical and social science students. Factors such as sex, marital status, faculty, and contact with individuals with end-stage organ failure did not significantly influence the knowledge and attitudes.

Conclusions:

This study highlights the necessity for educational interventions and awareness campaigns to improve understanding and attitudes towards organ donation among Northern Cyprus University students. Incorporating organ donation education into university curricula, providing accurate online information, addressing misconceptions, and promoting awareness of donation centers and transplant hospitals are essential steps to mitigate organ shortages. Public engagement should be encouraged to foster a supportive environment for organ donation.

Authors: Min Ji Young , Hyung Sung Woo , Jeon Joon Pyo , Chung Mee Young , Kim Chang Jae , Kim Yoon Hee
Published: June 2024

I-gel has been used in various clinical situations. The study investigated alterations in respiratory parameters following a stepwise lung recruitment maneuver (LRM) using the i-gel. The research involved 60 patients classified as American Society of Anesthesiologists class I-II, aged 30 to 75 years, undergoing elective urologic surgery. Various respiratory parameters, including lung compliance, airway resistance, leak volume, airway pressure, and oxygen reserve index, were recorded at different time points: before LRM, immediately after LRM, and at 5, 15, and 30 minutes after LRM, as well as at the end of the surgery. The primary outcome was to assess an improvement in lung compliance. Dynamic lung compliance (mean ± SD) was significantly increased from 49.2 ± 1.8 to 70.15 ± 3.2 mL/cmH2O (P < .05) after LRM. Static lung compliance (mean ± SD) was increased considerably from 52.4 ± 1.7 to 65.0 ± 2.5 mL/cmH2O (P < .05) after the LRM. Both parameters maintained a statistically significant increased status for a certain period compared to baseline despite a decreased degree of increment. Airway resistance (mean ± SD) was significantly reduced after the LRM from 12.05 ± 0.56 to 10.41 ± 0.64 L/cmH2O/s (P < .05). Stepwise LRM using i-gel may improve lung compliance and airway resistance. Repeated procedures could lead to prolonged improvements in respiratory parameters.

Alterations in signaling pathways and modulation of cell metabolism are associated with the pathogenesis of cancers, including hepatocellular carcinoma (HCC). Small ubiquitin-like modifier (SUMO) proteins and NF-κB family play major roles in various cellular processes. The current study aims to determine the expression profile of SUMO and NF-κB genes in HCC tumors and investigate their association with the clinical outcome of HCC. The expression of 5 genes – SUMO1, SUMO2, SUMO3, NF-κB p65, and NF-κB p50 – was quantified in tumor and adjacent non-tumor tissues of 58 HBV-related HCC patients by real-time quantitative PCR and was analyzed for the possible association with clinical parameters of HCC. The expression of SUMO2 was significantly higher in HCC tumor tissues compared to the adjacent non-tumor tissues (P = .01), while no significant difference in SUMO1, SUMO3, NF-κB p65, and NF-κB p50 expression was observed between HCC tumor and non-tumor tissues (P > .05). In HCC tissues, a strong correlation was observed between the expression of SUMO2 and NF-κB p50, between SUMO3 and NF-κB p50, between SUMO3 and NF-κB p65 (Spearman rho = 0.83; 0.82; 0.772 respectively; P < .001). The expression of SUMO1, SUMO2, SUMO3, NF-κB p65, and NF-κB p50 was decreased in grade 3 compared to grades 1 and 2 in HCC tumors according to the World Health Organization grades system. Our results highlighted that the SUMO2 gene is upregulated in tumor tissues of patients with HCC, and is related to the development of HCC, thus it may be associated with the pathogenesis of HCC.
Mediterranean diet: Fighting breast cancer naturally: A review
Authors: Yao Yuanning
Published: June 2024

The effects and mechanisms of the Mediterranean diet (MD) on the incidence, recurrence, and prevention of breast cancer (BC) have been extensively investigated since the 1990s. Recent years have witnessed significant advancements in understanding the relationship between the components of the MD and BC, particularly in terms of their role and adherence. This comprehensive review focuses on several key aspects: the influence of the adherence of MD in cohort studies conducted across different regions on BC, the effects and mechanisms of individual component or main components as well as the supplementation of vitamins, drugs, exercise, and other factors of MD on BC; the variations in the impact of the MD on premenopausal and postmenopausal women, as well as different types in BC cases; the possible mechanisms underlying the development, recurrence, and prevention of BC in relation to the MD; and the interaction effects of individual genetic polymorphisms with the MD. Based on current research findings, this review highlights the key issues and identifies future research directions in investigating the relationship between the MD and BC. Furthermore, it suggests that healthy women of various ages and BC patients should adhere to MD in order to prevent BC or improve the prognosis.

Published: June 2024

Background:

Combining hydromorphone with ropivacaine in ultrasound-guided erector spinae plane blocks enhances postoperative analgesia and reduces interleukin-6 expression in breast surgery patients.

Methods:

In this study, breast cancer patients undergoing modified radical mastectomy were randomized into 3 groups for anesthesia (30 patients in each group): standard general (group C), Erector Spinae Plane Block (ESPB) with ropivacaine (group R), and ESPB with ropivacaine plus hydromorphone (group HR). Diagnosis: Breast cancer patients. Postsurgery, pain levels, IL-6, anesthetic doses, additional analgesia needs, and recovery milestones were compared to evaluate the efficacy of the ESPB enhancements.

Results:

The 3 groups were not significantly different in baseline characteristics, operation time, number of cases with postoperative nausea, and serum IL-6 concentrations at T1 (the time of being returned to the ward after surgery). At T2 (at 6:00 in the next morning after surgery), the serum IL-6 concentration in group HR was significantly lower than that in groups R and C (P < .05); the intraoperative doses of remifentanil, sufentanil, and propofol were significantly lower in groups HR and R than those in group C (P < .05); Groups HR and R had significantly lower visual analog scale scores at T3 (4 hours postoperatively), T4 (12 hours postoperatively), and T5 (24 hours postoperatively) than those in group C (P < .05); the proportions of patients receiving postoperative remedial analgesia were significantly lower in groups HR and R than in group C (P < .05); groups HR and R had significantly lower proportions of patients with postoperative nausea than group C (P < .05); the time to the first anal exhaust and the time to the first ambulation after surgery were significantly shorter in groups HR and R than those in group C (P < .05).

Conclusion:

Hydromorphone combined with ropivacaine for ESPB achieved a greater postoperative analgesic effect for patients receiving MRM under general anesthesia. The combined analgesia caused fewer adverse reactions and inhibited the expression level of the inflammatory factor IL-6 more effectively, thereby facilitating postoperative recovery. ESPB using hydromorphone with ropivacaine improved pain control post-MRM, reduced adverse effects, and more effectively suppressed IL-6, enhancing recovery.

There has been significant interest in the changes in menstrual cycles following coronavirus disease 2019 (COVID-19) infection or vaccination. This study aimed to investigate the evidence for such changes and their potential risk factors. We used a descriptive study design and gathered data by sharing an online survey questionnaire on social media platforms. The questionnaire included questions regarding sociodemographic factors, menstrual cycle changes, and COVID-19 anxiety. The study population comprised women aged 18 to 49 years from Izmir. All data analyses were performed using Statistical Package for the Social Sciences 21.0. The risk factors influencing menstrual irregularities were determined after the COVID binary logistic regression analysis, including univariate and multivariate models. Among the 465 participants, those with an associate’s degree had a significantly higher risk of menstrual irregularities than those with a high school diploma (P = .012). Anxiety scores emerged as a significant risk factor for menstrual cycle irregularities (P = .026). However, neither COVID-19 infection nor vaccination resulted in significant changes in the menstrual cycle characteristics (P > .05). Other sociodemographic variables, such as age, body mass index, and smoking, were not significantly associated with menstrual cycle changes(P > .05). The study findings suggest that educational level and anxiety may play a role in menstrual irregularities, whereas COVID-19 infection or vaccination itself may not directly affect menstrual cycle.

We aimed to identify quality indicator for esophagogastroduodenoscopy for detecting upper gastrointestinal (UGI) cancer. Data from 43,526 consecutive health checkups from August 2012 to January 2022 were retrospectively collected. The study ultimately analyzed 42,387 examinations by 12 endoscopists who performed more than 1000 examinations, including all cancers detected. These endoscopists were classified either into fast/slow group based on their mean examination time for a normal finding of esophagogastroduodenoscopy during their first year of the examination, or small/large group based on number of endoscopic images, respectively. The association between UGI cancer detection rate and examination time or the number of images was analyzed, using 5 minutes or 50 images as cutoff values. The detection rate of overall (8 pharyngeal, 39 esophageal, 69 gastric) cancers in the fast, slow, small, and large groups were 0.17%, 0.32%, 0.21%, and 0.31%, respectively. On multivariable analysis, endoscopists in the fast group or the small group were less likely to detect overall UGI cancer (OR: 0.596, 95% CI: 0.373–0.952, P = .030; OR: 0.652, 95% CI: 0.434–0.979, P = .039). Additionally, repeated endoscopy within 2 years had a higher overall cancer detection rate, compared with repeated screening after 2 years. In a sub-analysis, a significant negative relationship was found between the detection rate of gastric cancer and the number of gastric images < 35 (OR: 0.305, 95% CI: 0.189–0.492, P = .000). There was also a negative correlation trend between the detection rate of pharyngeal and esophageal cancers and the number of esophageal images < 11 (OR: 0.395, 95% CI: 0.156–1.001, P = .050). The optimal number of images and screening 2-year interval are considered useful quality indicators for detecting UGI cancer. This study also suggests that a total of 50 images, or 35 images of the stomach are suitable for detecting UGI cancer, or gastric cancer, during screening endoscopy.

Published: June 2024

Introduction:

Iran follows global trends with a growing aging population. To better understand ageism in Iranian context, the present study explores the concept using a hybrid model with both inductive and deductive approaches.

Methods:

A hybrid concept analysis model was used to further define the concept of ageism. In the first step, databases such as PubMed, Web of Knowledge, Science Direct, and Google Scholar were searched for studies up until August 2019. Key terms used in the search included “ageism”, “stereotype”, “discrimination”, “age”, “aging” “old”, and “elder”. Subsequently, semi-structured interviews were conducted with 10 community-dwelling older adults chosen through purposive sampling.

Results:

Data from the theoretical and fieldwork phases presented a definition of ageism: “Ageism engrained into older adults (no other age groups) is associated with personal, psycho-social, economic, and especially cultural factors that impose an acceptance of limitations based on chronological age or being perceived as old”.

Conclusion:

Ageism is a multi-faceted experience composed of psycho-social, economic, and cultural dimensions. While the present study has further clarified ageism, more research is needed, particularly in relation to diverse cultural contexts.
Precision medicine in peripartum cardiomyopathy: advancing diagnosis and management through genomic and phenotypic integration
Authors: Singh Ajeet , Irfan Hamza , Ali Tooba , Mughal Sanila , Shaukat Ayesha , Jawwad Mohammad , Akilimali Aymar
Published: June 2024

Peripartum cardiomyopathy (PPCM) is a rare and life-threatening cardiac condition characterized by heart failure due to left ventricular systolic dysfunction, often developing in late pregnancy or the early postpartum period. Despite being a leading cause of maternal morbidity and mortality, clinical presentation of PPCM frequently overlaps with normal pregnancy-related physiological changes, causing diagnostic delays and increased complications. Current management strategies, primarily derived from general heart failure protocols, are evolving to address the unique aspects of PPCM. This includes the development of personalized medicine approaches that integrate genetic profiling, biomarker evaluation, and clinical phenotyping. Notable genes such as titin (TTN), Bcl2-associated athanogene 3 (BAG3), and lamin A/C (LMNA) are implicated in PPCM, revealing a complex genetic landscape similar to other cardiomyopathies. Biomarkers like N-terminal pro-brain-type natriuretic peptide (NT-proBNP) and cardiac troponin T (cTnT) are under investigation for their diagnostic and prognostic value, indicating that personalized treatments hold the promise of enhancing diagnostic precision and therapeutic outcomes by tailoring interventions to individual patient profiles. This review article aims to highlight how integrating genetic and phenotypic data can establish a novel framework for managing PPCM, potentially transforming treatment paradigms and improving long-term outcomes.

Authors: Abdallah Adam M. , Odat Ramez M. , Hanifa Hamdah , Shakhatreh Zaid , Sharqiah Qosay M. , Daoud Suleiman
Published: June 2024

Introduction and importance:

Malignant peripheral nerve sheath tumor (MPNST) is a rare and aggressive soft tissue malignant tumor. MPNST in the spinal canal is rarely seen except in cases of neurofibromatosis type 1. However, a long-segment extradural spinal malignant spindle cell neoplasm has not been reported in the current literature.

Case presentation:

We present the first reported case of spinal malignant spindle cell neoplasm extended along the spine. The detected lesion is responsible for compressing various segments of the spinal cord, causing thinning of the cord and secondary stenosis of the spinal canal, leading to a condition known as multisegment compression myelopathy.

Clinical discussion:

MPNSTs are typically detected late due to nonspecific symptoms, with a higher incidence in extremities and a notable occurrence in unusual locations. Diagnosis relies on MRI and histopathology, with S_100 positivity as a neural marker. MPNSTs can arise from neurofibromas or Schwann cells, with a significant portion resulting from TP53 mutations or secondary to radiation exposure.

Conclusion:

This case stands out due to its unique presentation, characterized by a predominantly spindle cell morphology with certain epithelioid features. It is imperative to recognize this condition for an accurate diagnosis, emphasizing the spindle cell-type MPNST and highlighting its exceptionally poor prognosis.

Published: June 2024

Introduction:

Hemophagocytic lymphohistiocytosis (HLH) is a rare hyperinflammatory disorder characterized by fever, cytopenia, splenomegaly, and hemophagocytosis. Without prompt treatment, HLH can rapidly progress to life-threatening multiorgan failure. The authors present a case of occult HLH with severe bicytopenia and organ dysfunction requiring intensive care.

Case presentation:

A 20-year-old male presented with fever, cough, and constitutional symptoms. He developed hypoxia, elevated transaminases, and bicytopenia. Despite transfusions, platelet counts remained critically low. With high suspicion for HLH, head computed tomography and bone marrow biopsy was although panned but couldn’t be performed due to resource less settings. And with suspicion for HLH treatment with high-dose dexamethasone was initiated as counts improved.

Clinical course:

The patient required mechanical ventilation for pulmonary infiltrates. He exhibited seizure activity and epistaxis related to coagulopathy. On hospital day 9, he was successfully extubated as counts normalized. He was discharged from the intensive care unit once stable.

Conclusion:

This case illustrates a delayed diagnosis of HLH masquerading as a fever of unknown origin. HLH should be urgently considered in patients with unexplained cytopenia, organ dysfunction, and systemic inflammation. Early treatment with immunotherapy can be lifesaving, whereas delays may precipitate irreversible end-organ damage.
Lower li1mb mesenchymal hamartoma masquerading as hemangioma: a case report of AA2 atypical presentation and diagnostic challenges
Authors: Puduru Nikhil , KA Dilip Vasant , Shaikh Faiza A. , Shaikh Humaira , Acharya Bimarsh , Sydhom Pishoy
Published: June 2024

Introduction and importance:

Hamartomas are abnormal growths that consist of various types of mesenchymal tissues, including cartilage, fat, connective tissue, and smooth muscle. These tumors can occur in almost any organ system within the body. While head and neck hamartomas have been frequently documented, cases involving the lower limbs are relatively rare. However, a unique instance of a mesenchymal hamartoma located in the leg has recently emerged.

Case presentation:

A 30-year-old woman presented with a painless, gradually growing swelling on her left leg, diagnosed as a subcutaneous hemangioma preoperatively. Despite unsuccessful propranolol treatment, surgical excision revealed a mesenchymal hamartoma. Postoperative examination confirmed the diagnosis, and the patient recovered smoothly without recurrence after a week of hospitalization.

Clinical discussion:

Cutaneous mesenchymal hamartomas are benign tissue growths with unknown etiology, associated with syndromes like Cowden and Peutz-Jeghers. Smooth muscle hamartoma can be acquired after skin trauma. Hemartoma can be misdiagnosed as hemangiomas. Cutaneous mesenchymal hamartomas presents as painless swellings in various locations, occasionally in adulthood. Differential diagnoses include lipomas and fibromas. Surgical excision is recommended for symptomatic cases to prevent recurrence.

Conclusion:

This case highlights the atypical presentation of the hamartoma and emphasizes the importance of accurate diagnosis and management.
