Coil embolization for ruptured and unruptured very small intracranial aneurysms: A retrospective review of a 10-year single-center experience
Authors: Ahn Jae Beom , Shin Hee Sup
Published: October 2023

Because of the risk of intraoperative rupture and technical difficulties, coil embolization of very small aneurysms (VSIAs) with a diameter of ≤3 mm is challenging. Herein, we reviewed our treatment strategies and outcomes in performing coil embolization for VSIAs compared to those for larger sized intracranial aneurysms (IAs) with 4 to 4.5 mm. We retrospectively reviewed the data on ruptured and unruptured VSIAs and larger-sized IAs treated with coiling from January 2012 to June 2021. Saccular IAs treated with coil embolization and followed up for at least 6 months with imaging studies were included in the study. Fifty-eight VSIAs (27 subarachnoid hemorrhages [SAH group] and 31 unruptured hemorrhages [URA group]) were identified. The wide-necked VSIAs were significantly more common in the URA group (90.3% vs 63.0%, P = .013). Procedural complications occurred in 8 cases (13.8%): intra-procedural rupture (n = 3), coil prolapse (n = 3), and thromboembolic events (n = 2). Complications were more frequent in the SAH group (P = .020). SAH was an independent risk factor for procedural complications (odds ratio, 11.293 [95% confidence interval: 1.173–108.684], P = .036), and the outcomes were affected by SAH presentation (P = .007) and poor clinical status of SAH (P = .001). When compared with larger IAs (n = 57), there were no significant differences in treatment outcomes, procedural complications, and clinical outcomes. VSIAs ≤ 3 mm in diameter were successfully treated with coil embolization, with reasonable procedure-related complications and treatment outcomes. The safety and efficacy of coil embolization for VSIAs were comparable to those of 4 to 4.5 mm sized IAs in this single-center cohort.
A case report of gastrointestinal hemorrhage caused by small intestinal hemangioma
Authors: Wei Yule , Yi Nan , Mo Yezhen , Liang Yunxiao
Published: October 2023

Rationale:

Small intestinal hemangioma is a rare condition and very difficult to diagnose preoperatively. It can occur in all segments of the small intestine, but jejunum is common. Its common symptoms are gastrointestinal bleeding and chronic anemia, while intussusception, intestinal obstruction and perforation are rare. In recent years, the popularization and application of capsule endoscopy, computed tomographic enterography and double-balloon enteroscopy play vital roles in the diagnosis and management of small bowel bleeding. We report a case of gastrointestinal hemorrhage caused by of the small intestine hemangioma.

Patient concerns:

A 56-year-old male complaint of hematochezia for 1 day with dizziness, fatigue, and vomiting of gastric contents.

Diagnosis:

Based on the clinical, laboratory, imaging tests, endoscopy, laparoscopic approach and pathological examination, the patient was diagnosed with small intestinal hemangioma.

Interventions:

Segmental resection was performed for the small intestinal hemangioma by a laparoscopic approach.

Outcomes:

The patient was discharged without operation complications, and his hemoglobin increased to 130 g/L at the second month after the operation.

Lessons:

Small intestinal hemangioma is a rare condition without specific symptoms and can cause gastrointestinal bleeding. The possibility of small intestinal hemangioma should be considered with unexplained gastrointestinal bleeding. Surgical resection is the preferred treatment option for symptomatic hemangiomas. Furthermore, double-balloon enteroscopy can increase the diagnostic yield. Applying endoscopic titanium clip combined with Indian ink marking can obtain an accurate positioning before surgery.
Does acupuncture improve the metabolic outcomes of obese/overweight children and adolescents?: A systematic review and meta-analysis
Authors: Quan Tingwei , Su Qi , Luo Yu , Su Xin , Chen Qiuxuan , Yang Jingjun , Tang Hongzhen
Published: October 2023

Background:

Although increasing evidence has revealed the efficacy of acupuncture in obesity/overweight, actual improvement in metabolism in children and adolescents is unclear. Therefore, we conducted a meta-analysis to evaluate this correlation.

Methods:

A comprehensive search was conducted using multiple databases, including Medline, Cochrane, Embase, Web of Science, Chinese Biomedical Literature Database, China National Knowledge Infrastructure, Chinese Scientific Journal Database, and Wan-fang Data, to identify relevant randomized controlled trials published before February 1, 2023. General information and data for the descriptive and quantitative analyses were extracted.

Results:

Fifteen randomized controlled trials of 1288 obese/overweight children and teenagers were included. All the trials were conducted in China and South Korea. Regarding quality assessment, no other significant risk of bias was found. The acupuncture groups were more likely to have improved metabolic indicators of obesity/overweight than the control groups, in terms of body mass index (standardized mean difference [SMD] = −0.45, 95% confidence interval [CI]: −0.69 to −0.21, I2 = 71.4%), body weight (SMD = −0.48, 95% CI: −0.92 to −0.05, I2 = 84.9%), and serum leptin (SMD = −0.34, 95% CI: −0.58 to −0.10, I2 = 91.8%). The subgroup analysis showed that for body mass index, the results were consistent regardless of the intervention duration, body acupuncture or auricular acupuncture combined with other interventions.

Conclusion:

Our results suggest that acupuncture is effective in improving metabolic outcomes of obese/overweight children and adolescents. Owing to the limited number of trials included in this study, the results should be interpreted with caution.
Predictive value of tumor mutational burden for PD-1/PD-L1 inhibitors in NSCLC: A meta-analysis
Authors: Li Wenjie , Zhao Yanjun , Zhang Hongjun , Zheng Wenying , Wang Ruixuan , Gu Xing
Published: October 2023

Background:

To investigate the association between tumor mutational burden (TMB) and the therapeutic effect of Programmed Death 1/Programmed Death Ligand 1 inhibitors in non-small cell lung cancer.

Methods:

Four electronic databases, PubMed, Embase, Web of Science, and Cochrane Library, were searched on May 10, 2023, and no time limitation was applied. Analyses were performed using STATA17.0. We assessed the methodological quality of each randomized controlled trial using the Newcastle-Ottawa scale.

Results:

After exhaustive database search and rigorous screening, 10 studies were included in the meta-analysis. Our findings indicate that high TMB significantly improves progression-free survival but reduces overall response rate. The overall survival was not significantly different between the high and low TMB groups. No significant publication bias was observed.

Conclusion:

High TMB serves as a potential predictive biomarker for improved progression-free survival and reduced overall response rate in patients with non-small cell lung cancer treated with programmed death 1/programmed death ligand 1 inhibitors. However, its predictive value in overall survival requires further investigation.
Potential roles of tumor microenvironment in gefitinib-resistant non-small cell lung cancer: A narrative review
Authors: Chen Mu-Tong , Li Bai-Zhi , Zhang En-Pu , Zheng Qing
Published: October 2023

During the course of treating non-small cell lung cancer (NSCLC) with epithelial growth factor receptor (EGFR) mutant, gefitinib resistance (GR) is unavoidable. As the environment for tumor cells to grow and survive, tumor microenvironment (TME) can significantly affect therapeutic response and clinical outcomes, offering new opportunities for addressing GR. Dynamic changes within the TME were identified during the treatment of gefitinib, suggesting the close relationship between TME and GR. Various dynamic processes like angiogenesis, hypoxia-pathway activation, and immune evasion can be blocked so as to synergistically enhance the therapeutic effects of gefitinib or reverse GR. Besides, cellular components like macrophages can be reprogrammed for the same purpose. In this review, we summarized recently proposed therapeutic targets to provide an overview of the potential roles of TME in treating gefitinib-resistant NSCLC, and discussed the difficulty of applying these targets in cancer treatment.
Systematic review and meta-analysis of the efficacy and safety of adjunctive use of tirofiban in patients treated with endovascular therapy for acute ischemic stroke at different embolic sites
Authors: Liu Chenxi , Yang Xun , Liu Mingsu , Wang Jinping , Li Guangqing
Published: October 2023

Background:

The use of tirofiban as an adjunct to endovascular therapy (EVT) for acute ischemic stroke has been controversial. We aimed to assess the differences in safety and efficacy of EVT adjuvant to tirofiban in patients with anterior circulation stroke (ACS) and posterior circulation stroke (PCS).

Methods:

We systematically searched Pubmed, Embase, Cochrane Library, and Web of Science. Cohort studies and randomized controlled trials that compared treatment with tirofiban combined with EVT and EVT alone were included in our meta-analysis. The safety outcomes were symptomatic intracranial hemorrhage, and 3-month mortality. The efficacy outcomes were good functional outcome, excellent functional outcome, and successful recanalization (mTICI ≥ 2b). We performed subgroup analyses of anterior and posterior circulation strokes.

Results:

We included 15 studies with 4608 patients. For safety outcomes, tirofiban significantly reduced 3-month mortality in the ACS subgroup (odd ratio [OR] = 0.80, 95% confidence interval [CI] = 0.65–0.98, P = .03) without increasing the rate of symptomatic intracranial hemorrhage (OR = 1.12, 95% CI = 0.88–1.44, P = .35). In the PCS subgroup, tirofiban significantly reduced 3-month mortality (OR = 0.63, 95% CI = 0.50–0.80, P = .0001) and symptomatic intracranial hemorrhage (OR = 0.60, 95% CI = 0.37–0.95, P = .03). For efficacy outcomes, in the ACS subgroup, tirofiban significantly improved good functional outcome (OR = 1.24, 95% CI = 1.06–1.45, P = .008) but did not improve recanalization (OR = 1.17, 95% CI = 0.93–1.47, P = .17) and excellent functional outcome (OR = 1.19, 95% CI = 0.97–1.46, P = .10). In the PCS subgroup, tirofiban significantly improved recanalization rate (OR = 1.94, 95% CI = 1.43–2.65, P < .0001) and did not improve good functional outcome (OR = 1.03, 95% CI = 0.81–1.30, P = .81) and excellent functional outcome (OR = 0.84, 95% CI = 0.58–1.20, P = .34).

Conclusion:

In acute ischemic stroke patients undergoing EVT, tirofiban improves good functional outcomes in ACS patients and increases recanalization rates in PCS patients on the 1 hand, reduces mortality, and does not increase the risk of symptomatic intracranial hemorrhage on the other. Tirofiban is safe and effective in both anterior circulation stroke and posterior circulation stroke patients undergoing EVT. More large multicentre randomized controlled studies are needed in the future.

Published: October 2023

Background:

Gastric cancer (GC) is highly biologically and genetically heterogeneous disease with poor prognosis. Increasing evidence indicates that biomarkers can serve as prediction and clinical intervention. Therefore, it is vital to identify core molecules and pathways participating in the development of GC.

Methods:

In this study, GSE54129, GSE56807, GSE63089, and GSE118916 were used for identified overlapped 75 DEGs. GO and Kyoto Encyclopedia of Genes and Genomes pathway analysis showed DEGs mainly enriched in biological process about collagen-containing extracellular matrix and collagen metabolic. Next, protein-protein interaction network was built and the hub gene was excavated. Clinicopathological features and prognostic value were also evaluated.

Results:

Hub genes were shown as below, FN1, COL1A2, COL1A1, COL3A1, COL4A1, COL6A3, COL5A2, SPARC, PDGFRB, COL12A1. Those genes were upregulation in GC and related to the poor prognosis (except COL5A2, P = .73). What is more, high expression indicated worse T stage and tumor, node, metastasis stage in GC patients. Later, the results of 25 GC tumor specimens and 34 normal tissues showed that FN1, COL3A1, COL4A1, SPARC, COL5A2, and COL12A1 were significantly upregulated in cancer samples.

Conclusion:

Our study systematically explored the core genes and crucial pathways in GC, providing insights into clinical management and individual treatment.

Authors: Chuang Te-Jung , Ko Chung-Wang , Shiu Sz-Iuan
Published: October 2023

Background:

Nonalcoholic fatty liver disease (NAFLD) or nonalcoholic steatohepatitis (NASH) is a leading cause of chronic liver disease worldwide with decreased life expectancy. Duodenal mucosal resurfacing (DMR) has been associated with metabolic improvement in glycemic and hepatic parameters of type 2 diabetes, but the metabolic impact of DMR for NAFLD/NASH remains inconclusive. We conducted a meta-analysis to investigate metabolic effects of DMR in patients with NAFLD/NASH.

Methods:

Three major bibliographic databases were reviewed for enrollment of trials prior to January 28, 2022. We included adults with biopsy-proven NAFLD/NASH or liver magnetic resonance imaging proton density fat fraction (MRI-PDFF) >5% at baseline and focused on the metabolic difference of MRI-PDFF at 12 weeks, and HbA1c or homeostatic model assessment index for insulin resistance (HOMA-IR) at 24 weeks.

Results:

Two studies involved a total of 67 participants for analysis. When compared with pre-intervention status, mean difference of MRI-PDFF, HbA1c, and HOMA-IR after DMR were −2.22 (95% CI: −12.79~8.34), −0.32% (95% CI: −0.80~0.16), and 0.15 (95% CI: −5.11~5.41) without statistical significance.

Conclusions:

For patients with NAFLD/NASH, DMR has the trend to improve liver fat at 12 weeks, and glycemic control in terms of HbA1c level at 24 weeks based on a very low quality of evidence.

Authors: Yokota Yuki , Hirose Satoshi , Hara Makoto , Nakajima Hideto
Published: October 2023

Autoimmune encephalitis (AE) subacutely causes severe and multiple symptoms; however, most patients achieve neurologically favorable outcomes. Despite the substantial recovery in motor function, persistent impairments in mental/social aspects lasting for several years have been recognized, and its potential effect on health-related quality of life (HRQOL) has been argued. To urgently evaluate the long-term effects of AE on patients’ HRQOL, we investigated patient-oriented long-term outcomes and assessed the HRQOL of patients with AE. Data of patients who were diagnosed with probable/definite AE, defined by Graus AE criteria 2016, and treated at our hospital between January 2011 and October 2020 were retrospectively retrieved. Their long-term (≥2 years) outcomes, which included various sequelae and handicaps in social activities such as returning to previous work/school life through structured interview forms, were evaluated, and the HRQOL was assessed using Neuro-QOL battery. We identified 32 patients who met the Graus AE criteria 2016 and eventually enrolled 21 patients in the study. The median interval between disease onset and survey period was 63 (25–156) months, and 43% of the patients had persistent neuropsychiatric symptoms, including memory disorders, personality changes, and seizures. No more than 71% returned to their previous work/school life. Although most of the patients had global QOL within normal limits, 48% had social QOL under normal limits. Patients with sequelae were significantly less likely to return to previous work/school and had worse global/social quality of life than patients without sequelae. In conclusion, nearly half of patients with AE had social QOL under normal limits 5 years after onset. The difficulty in returning to work/school and a worse HRQOL were notable in patients with sequelae.

Use network pharmacology combined with molecular docking to study the effects of Simiao-Yongan Decoction (SMYAD) intervenes in Knee Osteoarthritis (KOA) related targets and signaling pathways, and explores the molecular mechanism of SMYAD in treating KOA. The active ingredients and targets of SMYAD, which concluded 4 traditional Chinese medicines, were screened in TCMSP, and the related gene targets of KOA were screened in the disease databases GeneCards, MalaCards, DisGeNET, and Comparative Toxicogenomics Database, and their intersection data were obtained after integration. And used Cytoscape 3.9.1, the software topologies the network diagram of “compound—drug-active ingredient-target protein-disease.” Obtains the protein-protein interaction network diagram through STRING, and enriches and analyzes the obtained core targets. Carry out molecular docking matching verification on the main active ingredients and key targets of the drug. 106 active ingredients and 175 targets were screened from SMYAD to intervene in KOA, 36 core targets were obtained through protein-protein interaction screening, and 10 key targets played an important role. The enrichment results showed that the biological process of gene ontology mainly involved positive regulation of gene expression, negative regulation of apoptosis process, and positive regulation of apoptosis process. KEGG signaling pathway mainly involves AGE-RAGE signaling pathway in diabetic complications, TNF signaling pathway, hypoxia-inducible factor-1 signaling pathway, IL-17 signaling pathway. The pathway of Reactome mainly involves interleukin-4 and interleukin-13 signaling, cytokine signaling in immune system, immune system, apoptosis. Molecular docking showed that the mainly effective components of SMYAD can fully combine with TNF, IL1B, IL6, and CASP3. The results show that the main active ingredients and potential mechanism of action of SMYAD in the treatment of KOA have the characteristics of multiple targets and multiple pathways, which provides ideas and basis for further in-depth exploration of its specific mechanism.

The pandemic of COVID-19 is a traumatic event with distressing implications for mental health and several aspects of life. This study aimed to assess Post-traumatic Stress Disorder (PTSD) and Health-Related Quality of Life (HRQoL) among patients who experienced mild-to-moderate COVID-19 and their household contacts. This cross-sectional descriptive study was conducted between May 2020 and November 2020, in Ismailia and Suez governorates. A convenient sampling method was used. The sample size was calculated according to the prevalence of PTSD in COVID-19 patients to be 200 adult participants from both sexes, 100 patients with history of recent COVID-19 infection (up to 2 months after recovery) and their close family. COVID-19 was confirmed by a nasal swab sample tested by PCR in addition to suggestive symptoms and/or positive computed tomography lung findings. Data was collected by using the Arabic version of the Post-Traumatic Stress disorder checklist 5 (PCL5-PTSD) and the Arabic version of Health-Related Quality of Life (HRQoL). The questionnaire was collected through interviews at the Endemic and Infectious diseases and Family medicine outpatient clinics. Of the 200 studied participants, evidence of PTSD was found in 112 (56%) participants; all COVID-19 cases and 12 of their close-contact relatives. Impaired HRQoL was evident in 107 (53.5%) participants; all the COVID-19 cases and 7 contacts. The mean values total scores of the PTSD and HRQoL and its domains were significantly higher among cases compared to their contacts. The most frequently impaired domain was social (55%), psychological (54.5%), impairment (53.5%) followed by physical (48.5%) and the least was health perception (33.5%). The mean values of PTSD, HRQoL and their domains were significantly higher among participants who recalled respiratory symptoms and who had comorbid illness. The odds ratio of PTSD and HRQoL was 0.27 (95% CI: 0.2–0.36) and 0.3 (95% CI: 0.23–0.39) in participants who had more than a case of COVID-19 within their families. All the studied COVID-19 participants showed PTSD and impaired HRQoL, compared to 12% and 7% of their contacts, respectively. Past COVID-19 was associated with impairment of all domains of HRQoL and the most affected were the physical, psychological and impairment domains.
Senescence gene expression in clear cell renal cell carcinoma: Role of tumor immune microenvironment and senescence-associated survival prediction
Authors: Wu Yating , Li Xiaoyue
Published: October 2023

Clear cell renal cell carcinoma (ccRCC) constitutes the most prevalent histopathologic subtype of renal cell carcinoma. The interplay between aging and cancer is complicated, and we provide a relatively new set of senescence genes that has not yet been used in the study of clear cell renal cell carcinoma. Our objective is to investigate the involvement of senescence in the development and diagnosis of ccRCC. RNA-seq and clinical data for ccRCC was obtained from the cancer genome atlas and gene expression omnibus databases. Consensus clustering analysis was performed to identify novel molecular subgroups. Tumor immune status was assessed using estimating stromal and immune cells in malignancy using expression data, microenvironment cell populations, and single-sample gene set enrichment analysis analyses. Functional analysis, including gene ontology, gene set variation analysis, and gene set enrichment analysis, was conducted to explore potential mechanisms. A prognostic risk model was constructed using the LASSO algorithm and multivariate Cox regression analysis. Decision trees and nomograms were developed for survival prediction. SenMayo classified ccRCC patients into 2 molecular subtypes with significantly different survival rates, and significant differences in their immune status, characterized by poor prognosis with relatively high immune status. Besides, the differentially expressed genes between the 2 subgroups were mainly enriched in immune-related pathways. The burden of aging tissues and cells may lead to immune dysregulation and drug resistance, which could contribute to poor prognosis in ccRCC patients. Risk models, decision trees, and nomogram for ccRCC survival prediction have great potential applications. In conclusion, our study establishes a clear association between aging in ccRCC and the immune microenvironment, demonstrating the predictive potential of senescence genes for ccRCC prognosis.
Identification of two immune subtypes and four hub immune-related genes in ovarian cancer through multiple analysis
Authors: Tang Qin , Zhang Haojie , Tang Rong
Published: October 2023

Immune classification of ovarian cancer (OV) becomes more and more influential for its immunotherapy. However, current studies had few immune subtypes of OV. It is urgent to explore the immune subtypes and deeper hub immune-related genes (IRGs) of OV for follow-up treatment. A total number of 379 OV samples were obtained from UCSC online website. Single sample gene set enrichment analysis of 29 immune gene sets was used for identifying immune subtypes of OV and gene set variation analysis were used for exploring the hallmarks and Kyoto Encyclopedia of Genes and Genomes pathways of immune types. Two immunity subtypes (Immunity_H and Immunity_L) were identified by single sample gene set enrichment analysis. The OV patients in Immunity_H group had longer overall survival compared with those in Immunity_L group. The Immunity_H had higher stromal score, immune score and estimate score and the tumor purity had the adverse tendency. Besides, the gene set variation analysis enrichment results showed positive relationship between improved immunoreaction and pathways correlated to classical signaling pathway (PI3K/AKT/MTOR, P53, TNFA/NFkB signaling pathways) and immune responses (T/B cell receptor signaling pathways and primary immunodeficiency). Furthermore, 4 hub IRGs (CCR5, IL10RA, ITGAL and PTPRC) were jointly dug by weighted gene co-expression network construction and Cytoscape. Our team also explored the mutations of 4 hub IRGs and PTPRC showed nearly 7% amplification. Besides, 8 immune-checkpoint genes had higher expression in Immuity_H group compared with Immuity_L group, except CD276. The correlation between PD-1/PD-L1 and 4 hub IRGs were explored and gene set enrichment analysis were conducted to explore the underlying mechanisms of PTPRC in OV. Finally, western-blotting showed PTPRC could regulate immune checkpoint PD-L1 expression via JAK-STAT signaling pathway. In a word, 2 immune subtypes and 4 hub IRGs of OV were identified by multiple analysis.

Authors: Liu Liyu , Chen Bolin
Published: October 2023

The survival rate is significantly reduced in patients with colorectal cancer (CRC) who developing a second primary malignancy (SPM), and however, little has known about the factors that contribute to the mortality of SPMs among CRC survivors. This study aims to explore the influence factors in both the all-cause and cancer-specific mortality of patients with SPMs after CRC surgery. Data of adult CRC patients with SPMs were extracted from the Surveillance, Epidemiology, and End Results (SEER) database in this retrospective cohort study. The associations between potential influence factors and all-cause mortality and cancer-specific mortality were explored using univariate and multivariate Cox proportional hazards analyses. The evaluation indexes were hazard ratios (HRs), and 95% confidence intervals (CIs). We also drew pie charts to respectively reflect the distributions of SPMs sites and time interval in study population. A total of 1202 (56.14%) patients died for all-cause, and 464 (21.67%) died due to CRC. The results showed that after adjusting for covariates, age, sex, marital status, T stage of CRC, second primary cancer site, stage of SPMs, grade of SPMs, TNM stage of SPMs, and time interval were associated with all-cause mortality, while marital status, stage of CRC, T stage of CRC, chemotherapy, second primary cancer site, stage of SPMs, grade of SPMs, TNM stage of SPMs, and time interval were associated with cancer-specific mortality in patients with CRC. In addition, colon (23.5%) was the most common site of SPMs, followed by digestive system (19.0%), and the time interval between CRC and SPMs in most patients was over 5 years (28.4%). Our findings may assist clinicians to identify high-risk patients for SPMs after CRC surgery. Also, the postoperative long-term follow-up and close attention on the key systems where the SPMs may occur are of great necessary in patients with CRC.

In the United States (US), pressure ulcers affect ≤3 million people and costs exceed 26.8 billion US dollars in spending. To examine trends in primary pressure ulcer (PPU) hospitalization mortality, length of hospital stay (LOS), and inflation-adjusted charges (IAC) in the US from 2005 to 2014 by race/ethnicity. We secondarily examined the relationship between race/ethnicity with PPU mortality, LOS, and IAC with race/ethnicity. This cross-sectional study used Nationwide Inpatient Sample (NIS) data from 2005 to 2014. The study sample included all hospitalizations with the designated ICD-9-CM code of 707.20-25 (pressure ulcer). There was a notable decline in PPU hospitalization from 11.5% to 7.77 % between 2005 and 2014. The mean mortality decreased from 2.32% to 1.12% (P < .001), the mean LOS declined from 9.39 days (P < .001), and the mean IAC per hospitalization decreased from $30,935 to $29,432 (P < .001). Positive changes observed in mortality, LOS, and IAC trends were consistent across different racial and ethnic groups. The results of multivariable logistic and linear regression analyses revealed that Black patients (β = 0.68, 95% CI 0.36–1.01, P < .001) and patients belonging to the Other race/ethnic category (β = 0.93, 95% CI 0.18–1.69) had longer hospital stays compared to their White counterparts. Regarding IAC, Black patients (β = 2846, 95% CI 1254–4439, P < .005), Hispanic patients (β = 6527, 95% CI 4925–8130), and patients from the Other race/ethnic category (β = 3473, 95% CI 1771–5174) had higher IAC for PPU treatment compared to their White counterparts. PPU hospitalization discharges, as well as hospitalization mortality, LOS, and IAC, decreased during the study period, however, our findings revealed disparities in PPU outcomes among different racial/ethnic groups. Implications of the findings are discussed.

This study aimed to estimate dietary sodium and potassium consumption among Jamaicans and evaluate associations with sociodemographic and clinical characteristics. A cross-sectional study was conducted using data from the Jamaica Health and Lifestyle Survey 2016–2017. Participants were noninstitutionalized Jamaicans aged ≥15 years. Trained staff collected sociodemographic and health data via interviewer-administered questionnaires and spot urine samples. The Pan American Health Organization formula was used to estimate 24-hour urine sodium and potassium excretion. High sodium level was defined as ≥2000 mg/day, and low potassium levels as <3510 mg/day (World Health Organization criteria). Associations between these outcomes and sociodemographic and clinical characteristics were explored using multivariable ANOVA models using log-transformed 24-hour urine sodium and potassium as outcome variables. Analyses included 1009 participants (368 males, 641 females; mean age 48.5 years). The mean sodium excretion was 3582 mg/day (males 3943 mg/day, females 3245 mg/day, P < .001). The mean potassium excretion was 2052 mg/day (males, 2210 mg/day; females, 1904 mg/day; P = .001). The prevalence of high sodium consumption was 66.6% (males 72.8%, females 60.7%, P < .001) and that of low potassium intake was 88.8% (85.1% males, 92.3% females, P < .001). Sodium consumption was inversely associated with older age, higher education, and low glomerular filtration rate but was directly associated with being male, current smoking, and obesity. Overall, males had higher sodium consumption than women, with the effect being larger among hypertensive men. Women with hypertension had lower sodium consumption than nonhypertensive women; however, hypertensive men had higher sodium consumption than nonhypertensive men. Potassium consumption was higher among men, persons with obesity, and those with high total cholesterol but was lower among men with “more than high school” education compared to men with “less than high school” education. We conclude that most Jamaican adults have diets high in sodium and low in potassium. In this study, sodium consumption was directly associated with male sex, obesity, and current smoking but was inversely associated with older age and higher education. High potassium consumption was associated with obesity and high cholesterol levels. These associations should be further explored in longitudinal studies and population-based strategies should be developed to address these cardiovascular risk factors.

We described the proportion of adherence to the scheduled visual field (VF) examination and the associated factors in glaucoma patients in a tertiary referral center during the Coronavirus disease 2019 (COVID-19) outbreak in Taiwan. Patients with scheduled VF examinations during May 25th to July 12th, 2021, were retrospectively evaluated. Clinical characteristics including type of glaucoma, intraocular pressure (IOP) at the day of arranging VF examinations, prescriptions of anti-glaucoma medications, non-medical glaucoma treatment, length of glaucoma history, mean deviation (MD) of VF defect, and announcement of glaucoma progression were recorded. The associations between the adherence and the clinical factors were analyzed by univariate and multivariate logistic regression. There were 204 patients included, of which 37 patients (18.14%) adhered to VF examinations. A total of 161 patients (78.9%) were diagnosed with open-angle glaucoma (OAG), 27 patients (13.2%) with angle closure glaucoma, and 16 patients (7.8%) with glaucoma suspect. Most of the participants (41.2%) had mild VF defect and had been prescribed with no more than 1 bottle of anti-glaucoma medication. In the multivariate analysis, diagnosis of glaucoma suspect (P = .02) and history of SLT (P = .04) were significantly associated with better adherence. Glaucoma severity and the announcement of glaucoma progression were not significantly associated with adherence to VF examination. The COVID-19 pandemic had greatly influenced the adherence to VF examination in glaucoma patients. This study demonstrated that patients with the diagnosis of glaucoma suspect and history of SLT were more likely to adhere to VF examinations even during the COVID-19 pandemic.

To explore the value of applying different magnetic resonance imaging MRI sequences in the differential diagnosis of benign and malignant breast tumors. Routine breast magnetic resonance scans (T1-weighted image, T1WI; T2-weighted image, T2WI), dynamically enhanced scans, diffusion-weighted Imaging, and diffusion kurtosis imaging (DKI) scans were performed on 63 female patients with breast-occupying lesions. The benign and malignant lesions were confirmed by biopsy, excision-histopathology reports. There are 70 lesions, of which 46 are benign and 24 are malignant. Analyze the primary conditions, such as the shape, size, and boundary of the lesion, and determine the apparent diffusion coefficient (ADC), mean kurtosis (MK), and mean diffusion (MD) values. The receiver operating characteristic curve was used to evaluate the value and difference in differentiating benign and malignant lesions. In this study, the results of the 2 testers both showed that the MK of malignant lesions was significantly higher than that of benign lesions (P < .001), and the MD of benign lesions was higher than that of malignant lesions (P < .05). The ADC of benign lesions was higher than that of malignant lesions (P < .05). For MK, the area under the curve of the 2 testers was 0.855/0.869, respectively. When the best cutoff value of MK for tester 1 was 0.515, the sensitivity and specificity of MK for diagnosing malignant tumors were 83.3%/87.0%, respectively. For the 2 testers MD, and ADC, the area under the curve was < 0.5, and the diagnostic value was low. The MK value obtained by DKI has a specific value in the differential diagnosis of benign and malignant breast lesions. DKI is helpful in the identification of benign and malignant breast tumors. The diagnostic value is outstanding, and its importance to the changes in the microstructure of the organization needs to be further explored.

Authors: Lee Yong Woo , Lim Myung-Nam , Lee Jae Yeon , Yoo Yung-Ju
Published: October 2023

Background:

Optical coherence tomography (OCT) can detect visual alterations associated with Parkinson disease, such as damage to the retinal nerve fiber layer or changes in retinal vasculature. Macula thinning in association with Parkinson disease (PD) remains controversial. Therefore, we conducted a meta-analysis to investigate the central retina thickness in PD measured using spectral-domain OCT (SD-OCT).

Methods:

We searched PubMed and the Excerpta Medica database to identify studies that compared macular thickness between patients with PD and healthy controls published before July 31, 2021. A random-effects model was used to examine PD-associated changes in macular thickness. Meta-regression analysis was performed by assessing heterogeneity, publication bias, and study quality.

Results:

Thirty-two studies with a cross-sectional design were selected, including 2118 patients with PD and 2338 controls. We identified significant differences in the thickness of the ganglion cell–inner plexiform layer (standardized mean difference [SMD], –0.41; 95% confidence interval [CI], –0.66 to –0.16; I2 = 80%), ganglion cell complex (SMD, –0.33; 95% CI, –0.50 to –0.17; I2 = 0%), and of all inner and outer sectors of the macula (SMD range, –0.21 to –0.56; all P < .05) between patients with PD and controls.

Discussion:

These results corroborate the increased prevalence of changes in OCT measures in individuals with PD, highlighting the efficacy of SD-OCT–determined macular thickness as a biomarker for PD. Our findings may provide helpful guidelines for clinicians in rapidly evolving areas of PD diagnosis.

To compare the visual outcomes of early and late vitrectomy for breakthrough vitreous hemorrhage (VH) associated with exudative age-related macular degeneration (exudative AMD) and polypoidal choroidal vasculopathy (PCV). A retrospective chart review was performed with data of all patients diagnosed with exudative AMD and PCV-related breakthrough VH who underwent early or late vitrectomy (within or after 3 months, respectively). Demographic data and best-corrected visual acuity (BCVA) at baseline, and 1, 3, 6, and 12 months postoperatively were recorded and analyzed. Overall, 105 eyes with breakthrough VH were examined and categorized in either the early or late vitrectomy group. In the early and late vitrectomy group, LogMAR BCVA improved from 2.15 ± 0.08 and 2.07 ± 0.14 at baseline to 1.26 ± 0.09 and 1.27 ± 0.14 at 12 months, respectively (P < .001). Between early and late vitrectomy, the PCV subgroup demonstrated improved LogMAR BCVA at 1 year, but there was no statistically significant (P = .754). Conversely, the LogMAR BCVA improvement at 1 year in the early vitrectomy group demonstrated statistically significant differences from the late vitrectomy group (P = .025) in the exudative AMD subgroup. Both, early and late vitrectomy can improve visual acuity in patients with breakthrough VH secondary to exudative AMD and PCV. However, early vitrectomy is more beneficial for breakthrough VH-associated exudative AMD.

Diabetic nephropathy (DN) is a common and severe complication of diabetes mellitus and is the leading cause of chronic kidney disease (CKD) worldwide. Despite current treatments, many individuals with DN progress to end-stage renal disease (ESRD), requiring dialysis or kidney transplantation. The advancement in our understanding of the pathogenesis of diabetic nephropathy has led to the development of new prevention and treatment strategies. We comprehensively reviewed the literature on advances in the prevention and treatment of DN. We searched PubMed, Scopus, and Web of Science databases for articles published between 2000 and 2023, using keywords such as “diabetic nephropathy,” “prevention,” “treatment,” and “recent advances.” The recent advances in the prevention and treatment of DN include novel approaches targeting inflammation and fibrosis, such as inhibitors of the nuclear factor kappa-B (NF-kB) pathway, inhibitors of the transforming growth factor-beta (TGF-beta) pathway, and anti-inflammatory cytokines. Other promising strategies include stem cell therapy, gene therapy, and artificial intelligence–based approaches, such as predictive models based on machine learning algorithms that can identify individuals at high risk of developing DN and guide personalized treatment strategies. Combination therapies targeting multiple disease pathways may also offer the most significant potential for improving outcomes for individuals with DN. Overall, the recent advances in the prevention and treatment of DN represent promising avenues for future research and clinical development. Novel therapies targeting inflammation and fibrosis, stem cell and gene therapies, and artificial intelligence–based approaches all show great potential for improving outcomes for individuals with DN.

Published: October 2023

To analyze the predictive value of homocysteine (Hcy) combined with the Framingham risk score for cardio- and cerebrovascular disease in elderly patients with type 2 diabetes mellitus (T2DM) to provide a reference for clinical treatment. We retrospectively reviewed the clinical data of 1036 elderly patients with T2DM admitted to our hospital between July 2017 and July 2022. The patients were divided into occurrence (n = 438) and control (n = 598) groups based on the incidence of cardio- or cerebrovascular disease. Univariate and multivariate logistic analyses were used to analyze the factors associated with cardio-cerebral small-vessel disease in the elderly patients with T2DM. The predictive value of Hcy combined with the Framingham score for cardio- and cerebrovascular diseases in elderly patients with T2DM was determined using receiver operating characteristic curves. Univariate analysis showed that the occurrence group had significantly higher Framingham score, systolic blood pressure (SBP), total cholesterol (TC), fasting blood glucose (FBG), 2-hour postprandial plasma glucose, Hcy, glycated hemoglobin, smoking history, and disease duration than the control group (all P < .05). Food preferences, sleep duration, physical exercise, high density lipoprotein cholesterol (HDL-C), and low-density lipoprotein cholesterol levels were significantly lower in the occurrence group than in the control group (all P < .05). Multivariate logistic analysis showed that smoking history, duration of diabetes, Framingham score, SBP, TC, FBG, HDL-C, 2h postprandial plasma glucose, and Hcy levels were risk factors for cardio- and cerebrovascular disease in elderly patients with T2DM. The area under the curve for Hcy and Framingham scores was 0.741 (95% confidence interval [CI]: 0.635–1.871) and 0.717 (95% CI: 0.601–0.856), respectively. Hcy combined with the Framingham score demonstrated a significantly higher predictive value (0.852, 95% CI: 0.741–0.979). Long smoking history, long diabetes duration, high Framingham score, high SBP, high TC, high FBG, low HDL-C, and high Hcy levels are risk factors for cardio-cerebrovascular disease in elderly patients with T2DM. In addition, Hcy level combined with the Framingham score demonstrated superior predictive power for cardio- and cerebrovascular disease in elderly patients with T2DM.
FZD7: A potential biomarker for endometriosis
Authors: Lan Suwei , Zhang Zhengmao , Li Qing
Published: October 2023

Background:

Endometriosis is a chronic inflammatory, benign disorder that often co-occurs with adenomyosis and/or leiomyoma. The overall incidence of endometriosis in reproductive period women was nearly 10%. However, the exact mechanisms of endometriosis-associated pathogenesis are still unknown.

Methods:

In this study, we aimed to investigate whether Frizzled-7 (FZD7) would effectively promote the development of endometriosis. The microarray-based data analysis was performed to screen endometriosis-related differentially expressed genes. This process uncovered specific hub genes, and the nexus of vital genes and ferroptosis-related genes were pinpointed. Then, we collected human endometrial and endometriotic tissues from patients with endometriosis of the ovary (n = 39) and control patients without endometriosis (n = 10, who underwent hysterectomy for uterine fibroids) to compare the expression of FZD7.

Results:

These findings indicated that the expression of FZD7 was high compared with normal endometrium, and FZD7 may promote the progression of endometriosis.

Conclusion:

FZD7 may serve as a potential therapeutic target for endometriosis treatment.
Hemosiderin induced acute kidney injury requiring hemodialysis in patients with paroxysmal nocturnal hemoglobinuria: A case report
Authors: Choi Heejung , Yim Hyunee , Lee Min-Jeong
Published: October 2023

Rationale:

Paroxysmal nocturnal hemoglobinuria (PNH) is a rare hematopoietic stem cell disease with features of hemolytic anemia, thrombosis, and bone marrow failure. Due to intravascular hemolysis and hemoglobinuria, renal dysfunction is often accompanied in PNH patients.

Patient concerns:

A 25-year old woman presenting gross hematuria after coronavirus disease 2019 infection was admitted to our medical center. She had mild nausea and headache. She was diagnosed with iron deficiency anemia few years ago and had no other underlying disease. Her laboratory findings showed acute kidney injury (AKI) and severe anemia, with evidences of hemolysis.

Diagnosis:

Renal biopsy was done to determine the cause of renal failure and the result was acute tubular necrosis with deposition of golden pigments, hemosiderin. With pathologic result and laboratory finding of hemolysis, we did flow cytometry for PNH, and the patient was finally diagnosed with PNH.

Interventions:

With AKI and oliguria, the patient started to take hemodialysis.

Outcomes:

After taking 5 sessions of hemodialysis, the patient’s renal function was recovered from AKI. With diagnosis of PNH, the patient is now being treated with complement C5 inhibitor.

Lessons:

This challenging case tells us that we should consider the first manifestation of PNH as a cause of severe AKI requiring hemodialysis in a patient with anemia and evidence of hemolysis.
