Comparison of dexmedetomidine with midazolam for third molar surgery: A meta-analysis of randomized controlled trials
Authors: Wang Ling , Yang Hongmei , Le Xi
Published: June 2023

Introduction:

The analgesic sedation of dexmedetomidine compared with midazolam for third molar surgery remains controversial. We conduct a systematic review and meta-analysis to explore the influence of dexmedetomidine versus midazolam for third molar surgery.

Methods:

We have searched PubMed, EMbase, Web of science, EBSCO, and Cochrane library databases through December 2022 for randomized controlled trials assessing the effect of dexmedetomidine versus midazolam for third molar surgery. This meta-analysis was performed using the random-effect model.

Results:

Four randomized controlled trials were included in the meta-analysis. Overall, compared with midazolam for third molar surgery, dexmedetomidine administration leads to comparable oxygen saturation (standard mean difference [SMD] = 0.25; 95% confidence interval [CI] = −0.24 to 0.74; P = .31), heart rate (SMD = −0.37; 95% CI = −1.18 to 0.44; P = .37), SBP (SMD = −0.24; 95% CI = −0.57 to 0.09; P = .16), DBP (SMD = −0.26; 95% CI = −0.60 to 0.07; P = .12), as well as nausea and vomiting (OR = 0.58; 95% CI = 0.05–6.61; P = .66).

Conclusions:

Dexmedetomidine may obtain the comparable sedation efficacy with midazolam for third molar surgery.
The association between aldehydes exposure and female infertility: A cross-sectional study from NHANES
Authors: Zhang Wenchao , Cui Yugui , Liu Jiayin
Published: June 2023

Environmental pollutants could be implicated in the cause of female infertility beyond traditional factors. Until now, no study has focused on the association of environmental exposure to aldehydes with female infertility. This study intended to investigate the possible impact of serum levels of aldehyde on female infertility. A cross-sectional study was performed on 516 nationally representative participants from 2013 to 2014 National Health and Nutrition Examination Survey (NHANES) in US. Multivariate logistic regression models and restricted cubic splines were used to examine the association between serum levels of aldehydes and the risk of female infertility. Women in the highest tertile of exposure to benzaldehyde had a 66% (odds ratio [OR] = 0.34, 95% confidence interval [CI] = 0.14–0.79) lower risk of infertility compared to those in the lowest tertile, after adjusting for other variables. Restricted cubic spline indicated a linear and negative association of benzaldehyde with female infertility (p for nonlinearity = 0.74), while other aldehydes did not exhibit a significant correlation. In summary, this cross-sectional study indicates that higher benzaldehyde level correlated with a lower rate of female infertility, which could help guide future research and contribute to the development of interventions to prevent or treat infertility and improve reproductive health outcomes.

Authors: Ma Ling-Hui , Zhang Zhou , Ma Liang-Xiao , Mu Jie-Dan , Qian Xu , Zhang Qin-Yong , Sun Tian-Yi
Published: June 2023

Background:

Hypertension is a predominant risk factor for cardiovascular disease and has imposed a global disease burden. Poor medication compliance is the major obstacle to antihypertensive drug therapy, and negative mood status is also detrimental to blood pressure (BP) management. While transcutaneous electrical acupoint stimulation (TEAS), as an electrical stimulation modality for biofeedback physical regulation based on acupoints, offers a such nondrug alternative option that is noninvasive, safe, and effective with high adherence. However, the optimal stimulation parameters of TEAS for hypertension remain unclear, especially the frequency, which needs further exploration.

Objective:

The study aims to investigate the efficacy of TEAS for hypertension, and to screen the optimal electrical stimulation frequency.

Methods:

This is an 8-week, randomized, controlled pilot trial with 3 parallel groups. In a ratio of 1:1:1, 120 patients with stage 1 hypertension will be divided into the TEAS-2Hz group, TEAS-10Hz group, or usual care group. All patients will receive the usual care for hypertension including lifestyle education, etc. Additionally, the 2 TEAS groups will receive 12 sessions of TEAS interventions at 2 Hz or 10 Hz, 3 times weekly for 30 minutes each, with 4 weeks of follow-up. The main outcome will be the change from baseline to week 4 in systolic BP among the groups. Secondary outcomes consist of changes in diastolic BP, mean arterial pressure, heart rate, heart rate variability, medication adherence, and quality of life. The safety outcomes will be any adverse event during the treatment.

Discussion:

As a pre-study for the next large clinical trial of TEAS for hypertension, this study will offer references for optimized frequency of biofeedback electrical devices and promote more consciousness of the benefits of body-mind holistic regulation of BP, thereby achieving proactive and overall process management of BP.

Authors: Xiao Ganchen , Zhao Yingtao , Chen Xingyu , Xiong Fangli
Published: June 2023

Background:

Traditional Chinese medicine advocates the use of acupuncture for the treatment of postprandial distress syndrome (PDS) in people with Functional dyspepsia, but large clinical trials of acupuncture have produced controversial results. This study aims to confirm the clinical significance of acupuncture in the treatment of PDS .

Methods:

This study only randomized controlled trials were included from the following databases: CNKI, Medline, Cochrane Central, Web of Science, and Clinical Trial. The risk of bias in the included studies was assessed using Revman 5.4.1 (Revman 2020), and all 12 included studies were considered to have a low risk of bias. This study used Stata 16.1 for data analysis, including sensitivity analysis and publication bias test. The quality of each study was evaluated with the Cochrane tool. The main outcomes included the overall therapeutic rate, the SID score, the HADS Score, The NDI score, and Side effects.

Results:

This study identified a total of 1532 studies interested in the curative effect of acupuncture on Postprandial discomfort syndrome (PDS) and finally included a total of 12 studies with 1113 patients after identifying their abstracts, titles, and full text. The process of literature searches and identifying is shown in Figure 1 and data analysis showed that acupuncture is effective in the treatment of PDS and promotes the life quality of patients.

Conclusions:

This study analyzed the effects of acupuncture on PDS from 5 aspects: overall therapeutic rate, SID, HADS, NDI, and side effects, overall therapeutic rate as primary outcome measure. Statistical analysis results showed that acupuncture has a significant effect on the treatment of PDS. In conclusion, it is an effective clinical treatment method. Also, the potential bias in the included studies, high-quality studies are needed to further confirm the possible side effects of acupuncture in treatment.
Research progress of neuroinflammation-related cells in traumatic brain injury: A review
Authors: Zhao Qinghui , Li Huige , Li Hongru , Xie Fei , Zhang Jianhua
Published: June 2023

Neuroinflammation after traumatic brain injury (TBI) is related to chronic neurodegenerative diseases and is one of the causes of acute secondary injury after TBI. Therefore, it is particularly important to clarify the role of cellular mechanisms in the neuroinflammatory response after TBI. The objective of this article is to understand the involvement of cells during the TBI inflammatory response (for instance, astrocytes, microglia, and oligodendrocytes) and shed light on the recent progress in the stimulation and interaction of granulocytes and lymphocytes, to provide a novel approach for clinical research. We searched articles in PubMed published between 1950 and 2023, using the following keywords: TBI, neuroinflammation, inflammatory cells, neuroprotection, clinical. Articles for inclusion in this paper were finalized based on their novelty, representativeness, and relevance to the main arguments of this review. We found that the neuroinflammatory response after TBI includes the activation of glial cells, the release of inflammatory mediators in the brain, and the recruitment of peripheral immune cells. These inflammatory responses not only induce secondary brain damage, but also have a role in repairing the nervous system to some extent. However, not all of the mechanisms of cell-to-cell interactions have been well studied. After TBI, clinical treatment cannot simply suppress the inflammatory response, and the inflammatory phenotype of patients’ needs to be defined according to their specific conditions after injury. Clinical trials of personalized inflammation regulation therapy for specific patients should be carried out in order to improve the prognosis of patients.
Multiple epithelioid angiosarcoma of stomach and small intestine with multiple lymph node metastases: A case report
Authors: Yu Jun-Hua , Cao Lu-Lu , Qian Jun
Published: June 2023

Rationale:

Angiosarcoma is a mesenchymal soft tissue sarcoma with a tendency for vascular endothelial differentiation. It is highly malignant with a poor prognosis but has a low incidence. Epithelioid angiosarcoma of the gastrointestinal tract is rare, and simultaneous multiple lesions of the stomach and small intestine are even rarer. It is easy to be misdiagnosed clinically. We report on a case of preoperative misdiagnosis of gastric cancer and postoperative diagnosis of epithelioid angiosarcoma with multiple lymph node metastases.

Patient concerns:

A 75-year-old patient who was admitted to the hospital because of fatigue, melena and dysuria for >1 month.

Diagnosis, interventions and outcomes:

Gastroscopy revealed gastric fundus ulcer and the biopsy revealed poorly differentiated adenocarcinoma of the fundus. We performed a radical gastrectomy for gastric cancer during which multiple ulcers were found in the jejunum and resected. Postoperative pathology showed multiple epithelioid angiosarcoma in the stomach and small intestine with lymph node metastases. The patient did not receive further treatment and died 2 month after the surgery.

Lessons:

Gastrointestinal epithelioid angiosarcoma is one of the differential diagnoses of gastrointestinal adenocarcinoma and surgery is the main treatment. The lymph nodes are one of the main sites of metastasis.
Neurosarcomatous amelanotic transformation of malignant melanoma presenting as malignant periopheral nerve sheath tumor: Rare case report
Authors: Bofan Lu , Xiaofei Xiu , Jingwen Zhang , Zuzhuo Zhang , Tianxiao Ma , Feng Gao , Guochuan Zhang , Zhou Zhuang
Published: June 2023

Rationale:

Malignant melanoma (MM) is notorious for its remarkable morphological variation and aberrant histopathological patterns. In addition, Malignant Periopheral Nerve Sheath Tumor (MPNST) is an uncommon but aggressive soft tissue sarcoma. Because of the common embryological origin of melanocytes and Schwann cells in the neural crest, discriminating between a particular type of MM and MPNST can be difficult, particularly when they are amelanotic. Our goal is to increase awareness among clinicians of the rare variations of MM and the importance of medical history in improving the accuracy of the final clinical diagnosis.

Patient concerns:

A 68-year-old man was admitted to the hospital due to pain in his right ankle, which had persisted for 8 months, along with swelling for 4 months. Medical history revealed delayed healing of right plantar for 5 years after a traumatic injury.

Diagnoses:

The ankle mass was initially diagnosed as MPNST through biopsy. After reviewing the patient’s medical history and receiving the final pathological report following amputation, we have revised the diagnosis to metastatic amelanotic desmoplastic melanoma in the ankle part and lentigo maligna melanoma in the plantar part. This is due to both lesions displaying positive markers or mutated genes in immunohistology and Gene Mutation Detection, indicating homology between the 2 tumors.

Interventions:

Due to the malignant characteristics of the tumor and the patient’s wishes, amputation of the right lower leg was carried out.

Outcomes:

Subsequently, the patient was treated with interferon-γ and immunosuppressant PD-1 inhibitor, and survived for 1 year after amputation.

Lessons:

Clinical data, immunohistochemisty biomarkers and genes detection results can serve as valuable evidence for pathologists and clinicians in identifying the disease process. Collaborative efforts between clinicians and scientists are crucial in order to identify specific markers that can effectively differentiate between the 2 tumors, thereby enhancing the conclusiveness of the diagnosis.
A meta-analysis of randomized controlled trials of tonifying kidney and strengthen bone therapy on nondialysis patients with chronic kidney disease-mineral and bone disorder
Authors: Wu Guiling , Li Liang , Wu Zijian
Published: June 2023

Background:

Correction of calcium, phosphorus, and parathyroid hormone disorders is the standard of treatment in nondialysis patients with chronic kidney disease-mineral and bone disorder (CKD-MBD). However, the side effects and adverse reactions are still the main problems. Moreover, the lack of protection of kidney function in the treatment dramatically affects patients’ health. Although Traditional Chinese Medicine, specifically tonifying kidney and strengthen bone (TKSB) therapy, is wildly applied to patients with CKD-MBD in China, the evidence of TKSB therapy in the treatment of CKD-MBD is limited. Thus, we conducted this meta-analysis to evaluate the efficacy and safety of TKSB therapy combined with Western medicine (WM) for nondialysis patients with CKD-MBD.

Methods:

Two investigators conducted systematic research of randomized controlled trials of TKSB therapy for CKD-MBD from 7 electronic databases. Methodological quality evaluations were performed using the Cochrane collaboration tool, and data analysis was conducted by RevMan v5.3 software and STATA v15.0.

Results:

In total, 8 randomized controlled trials involving 310 patients met the criteria of meta-analysis. The complete results showed that compared with WM alone, TKSB treatment could improve the clinical efficacy rate (risk ratio = 4.49, 95% confidence interval [CI]: [2.64, 7.61], P  .00001), calcium (weighted mean difference [WMD] = 0.11, 95% CI: [0.08, 0.14], P < .00001), serum creatinine (WMD = 45.58, 95% CI: [32.35, 58.8], P < .00001) phosphorus (WMD = 0.11, 95% CI: [0.08, 0.13], P < .00001), parathyroid hormone (WMD = 16.72, 95% CI: [12.89, 20.55], P < .00001), blood urea nitrogen levels (WMD = 0.95, 95% CI: [0.26, 1.64], P = .007) on nondialysis patients with CKD-MBD, which was beneficial to improve the patients’ bone metabolic state and renal function. In addition, evidence shows that, compared with WM alone, TKSB treatment is safe and does not increase side effects.

Conclusion:

The systematic review found that TKSB therapy combined with WM has a positive effect on improving renal function and correcting bone metabolism disorder in nondialysis patients with CKD-MBD, which shows that Traditional Chinese Medicine is effective and safe in treating CKD-MBD. However, more high-quality, large-sample, multicenter clinical trials should be conducted to assess the safety and efficacy of TKSB therapy in treating nondialysis patients with CKD-MBD.

The 10 top-cited authors who published papers in journal medicine since 2000 using the betweenness centrality to identify unique names: Bibliometric analysis
Authors: Chang Chi-Sheng , Chow Julie Chi , Chien Tsair-Wei , Cheng Bor-Wen , Chou Willy
Published: June 2023

Background:

Numerous studies have explored the most productive and influential authors in a specific field. However, 2 challenges arise when conducting such research. First, some authors may have identical names in the study data, and second, the contributions of coauthors may vary in the article by line, requiring consideration. Failure to address these issues may result in biased research findings. Our objective was to illustrate how the author-weighted scheme (AWS) and betweenness centrality (BC) can be employed to identify the 10 most frequently cited authors in a particular journal and analyze their research themes.

Methods:

We collected 24,058 abstracts from the PubMed library between 2000 and 2020 using the keyword “Medicine [Journal].” Author names, countries/regions, and medical subject headings (MeSH terms) were collected. The AWS to identify the top 10 authors with a higher x-index was applied. To address the issue of authors with identical names affiliated with different research institutes, we utilized the BC method. Social network analysis (SNA) was conducted, and 10 major clusters were identified to highlight authors with a higher x-index within the corresponding clusters. We utilized SNA to analyze the MeSH terms from articles of the 10 top-cited authors to identify their research themes.

Results:

Our findings revealed the following: within the top 10 cited authors, 2 authors from China shared identical names with Jing Li and Tao-Wang; JA Winkelstein from Maryland (US) had the highest x-index (15.58); Chia-Hung Kao from Taiwan was the most prolific author, having published 115 articles in Medicine since 2003; and the 3 primary research themes, namely, complications, etiology, and epidemiology, were identified using MeSH terms from the 10 most frequently cited authors.

Conclusions:

Using AWS and BC, we identified the top 10 most cited authors. The research methods we utilized in this study (BC and AWS) have the potential to be applied to other bibliometric analyses in the future.
Analysis of the association between serum antiaging humoral factor klotho and cardiovascular disease potential risk factor apolipoprotein B in general population
Authors: Chen Zhiyi , Tao Tao , Huang Guixiao , Tong Xin , Li Qinhe , Su Guanyu
Published: June 2023

Cardiovascular disease (CVD) is a prevalent health issue, and various risk factors contribute to its development, including blood lipids, blood pressure, diabetes, smoking, and alcohol consumption. Apolipoprotein B (ApoB) is related to CVD. ApoB is present on the surface of low-density lipoprotein (LDL), and its cellular recognition and LDL uptake are mainly achieved through recognition. It plays a crucial role in the diagnosis and treatment of CVD. This study aims to investigate the relationship between Klotho and ApoB in the general population of the United States as the correlation between serum Klotho and apoB is currently unknown. These findings could potentially guide the development of future treatments for CVD. This study utilized data from the National Health and Nutrition Examination Survey (NHANES) collected between 2007 and 2016. A linear regression model and smooth curve fitting were conducted to analyze the relationship between serum Klotho and apoB. The results indicate a negative correlation between serum Klotho concentration and apoB concentration (β = −71.7; 95% confidence interval [CI]: −120.8, −22.6; P = .005). After adjusting for confounding variables, the negative correlation between apoB concentration and serum Klotho concentration became more significant (β = −91.8; 95% CI: −151.3, −32.2; P = .004). When apoB concentration was converted from a continuous variable to a categorical variable (tertiles: T1 <0.8 g/L; T2: ≥0.8 g/L to <1.0 g/L; T3: ≥1.0 g/L), the serum klotho level of participants in the highest tertile (≥1.0 g/L) was −44.8 pg/mL (95% CI: −86.3, −3.2; P = .040) lower than that in the lowest tertile (<0.8 g/L). The smooth curve fitting diagram revealed differences in the relationship between serum Klotho concentration and apoB among individuals with different CVD risk factors. This study demonstrates a significant negative correlation between serum Klotho concentration and apoB concentration, even after controlling for confounding factors. The findings suggest that serum Klotho and apoB may be involved in the development of CVD, and targeting these factors could be a potential approach for CVD prevention and treatment.
Analyzing the number of articles with network meta-analyses using chord diagrams and temporal heatmaps over the past 10 years: Bibliometric analysis
Authors: Liang Yu-Erh , Ho Sam Yu-Chieh , Chien Tsair-Wei , Chou Willy
Published: June 2023

Background:

Network meta-analyses (NMAs) are statistical techniques used to synthesize data from multiple studies and compare the effectiveness of different interventions for a particular disease or condition. They have gained popularity in recent years as a tool for evidence-based decision making in healthcare. Whether publications in NMAs have an increasing trend is still unclear. This study aimed to investigate the trends in the number of NMA articles over the past 10 years when compared to non-NMA articles.

Methods:

The study utilized data from the Web of Science database, specifically searching for articles containing the term “meta-analysis” published between 2013 and 2022. The analysis examined the annual number of articles, as well as the countries, institutions, departments, and authors associated with the articles and the journals in which they were published. Ten different visualization techniques, including line charts, choropleth maps, chord diagrams, circle packing charts, forest plots, temporal heatmaps, impact beam plots, pyramid plots, 4-quadrant radar plots, and scatter plots, were employed to support the hypothesis that the number of NMA-related articles has increased (or declined) over the past decade when compared to non-NMA articles.

Results:

Our findings indicate that there was no difference in mean citations or publication trends between NMA and non-NMA; the United States, McMaster University (Canada), medical schools, Dan Jackson from the United Kingdom, and the Journal of Medicine (Baltimore) were among the leading entities; NMA ranked highest on the coword analysis, followed by heterogeneity, quality, and protocol, with weighted centrality degrees of 32.51, 30.84, 29.43, and 24.26, respectively; and the number of NMA-related articles had increased prior to 2020 but experienced a decline in the past 3 years, potentially due to being overshadowed by the intense academic focus on COVID-19.

Conclusion:

It is evident that the number of NMA articles increased rapidly between 2013 and 2019 before leveling off in the years following. For researchers, policymakers, and healthcare professionals who are interested in evidence-based decision making, the visualizations used in this study may be useful.
Assessing ChatGPT’s capacity for clinical decision support in pediatrics: A comparative study with pediatricians using KIDMAP of Rasch analysis
Authors: Kao Hsu-Ju , Chien Tsair-Wei , Wang Wen-Chung , Chou Willy , Chow Julie Chi
Published: June 2023

Background:

The application of large language models in clinical decision support (CDS) is an area that warrants further investigation. ChatGPT, a prominent large language models developed by OpenAI, has shown promising performance across various domains. However, there is limited research evaluating its use specifically in pediatric clinical decision-making. This study aimed to assess ChatGPT’s potential as a CDS tool in pediatrics by evCDSaluating its performance on 8 common clinical symptom prompts. Study objectives were to answer the 2 research questions: the ChatGPT’s overall grade in a range from A (high) to E (low) compared to a normal sample and the difference in assessment of ChatGPT between 2 pediatricians.

Methods:

We compared ChatGPT’s responses to 8 items related to clinical symptoms commonly encountered by pediatricians. Two pediatricians independently assessed the answers provided by ChatGPT in an open-ended format. The scoring system ranged from 0 to 100, which was then transformed into 5 ordinal categories. We simulated 300 virtual students with a normal distribution to provide scores on items based on Rasch rating scale model and their difficulties in a range between −2 to 2.5 logits. Two visual presentations (Wright map and KIDMAP) were generated to answer the 2 research questions outlined in the objectives of the study.

Results:

The 2 pediatricians’ assessments indicated that ChatGPT’s overall performance corresponded to a grade of C in a range from A to E, with average scores of −0.89 logits and 0.90 logits (=log odds), respectively. The assessments revealed a significant difference in performance between the 2 pediatricians (P < .05), with scores of −0.89 (SE = 0.37) and 0.90 (SE = 0.41) in log odds units (logits in Rasch analysis).

Conclusion:

This study demonstrates the feasibility of utilizing ChatGPT as a CDS tool for patients presenting with common pediatric symptoms. The findings suggest that ChatGPT has the potential to enhance clinical workflow and aid in responsible clinical decision-making. Further exploration and refinement of ChatGPT’s capabilities in pediatric care can potentially contribute to improved healthcare outcomes and patient management.

Authors: Peng Xiaoyan , Sun Hui , Wang Lingxiao , Guo Wanji , Zhao Zhenxiang , Yang Jian
Published: June 2023

To study the difference of clinical characteristics and prognostic factors from elderly patients with renal cell carcinoma (RCC), the statistical analysis was carried out based on the surveillance, epidemiology, and end results database. The relevant clinical information of 19,472 RCC patients from 2010 to 2015 were collected, and the differences of clinicopathological characteristics and survival rate was analyzed by log-rank method and Chi square test, respectively. Multivariate Cox regression model was used to explore the independent risk factors affecting the long-term survival of RCC patients. Results showed that the proportion of elderly RCC patients in the 60–64-year group in 2010 was 15.20%, but the value elevated to 18.51% in 2015, and the Chi-square test revealed the significant correlation between elderly RCC patients with gender, race, American Joint Committee on cancer stage, T stage, N stage, and M stage. The difference of survival time between the 60–69 year, 70–79 year, 80–84 year, and 85+ year group was significant, and Kaplan–Meier analysis showed a negative effects of age on survival rate of RCC patients, indicating a worsening trend with increasing age. Cox proportional hazards model analysis further confirmed that age was the important independent prognostic factor. Our study reveals that the onset age of RCC in elderly population is gradually decreasing, and the malignant degree of elderly RCC patients is increasing with age. The female elderly population could be more susceptible to RCC than male elderly population, and 85+ year population could also be cancer susceptible with a higher lymph node metastasis rate, later tumor stage, and poor prognosis, suggesting that these elderly populations should pay more attention to the RCC screening.

Published: June 2023

Visceral obesity is an important factor that increases the risk of complications after colorectal cancer surgery. As calculating visceral fat is difficult and time-consuming, more practical fat measurements that are not time-consuming have been introduced. This study aimed to investigate the effects of perirenal fat thickness on postoperative complications and prognosis in patients undergoing surgery for colorectal cancer. Perirenal fat thickness was measured from the dorsal aspect of the left kidney on preoperative computerized tomography of patients who underwent surgery for colorectal cancer. The effects of perirenal fat thickness on postoperative complications were investigated. Diagnostic test performance was examined using the Roc Curve test to determine the cutoff value for the perirenal fat thickness values according to the complication findings of the patients. The cutoff value of perirenal fat thickness was found to be above 25.1, according to the presence of complications in the patients. Those with a perirenal fat thickness greater than 25.1 mm were considered to have high perirenal fat thickness values, and those with a low perirenal fat thickness value were considered low. Multivariate analysis revealed that increased perirenal fat thickness is an independent risk factor for postoperative complications. We believe that perirenal fat thickness measurement, as an indicator of visceral fat volume, can be used to identify patients at high risk of developing complications after colorectal cancer surgery. This may change the disease management and affect the patient information process.
Clinical efficacy of belimumab in central nervous system demyelinating syndromes with systemic lupus erythematosus: A case series
Authors: Liu Ya , Fan Qiuyu , Jia Chao , Wan Qibin , Yang Huiqin
Published: June 2023

Rationale:

Systemic lupus erythematosus (SLE) is a complex autoimmune disease involving multiple systems. Central nervous system (CNS) demyelinating syndromes are one of the rare neurological manifestations of SLE, whose diagnosis, treatment, and prognosis are rarely reported. Belimumab, an anti-BAFF monoclonal antibody, has been approved by the FDA for the treatment of SLE. We aimed to assess the effects of belimumab on demyelinating syndromes in patients with SLE.

Patient concerns:

Six patients with demyelination in SLE who were managed at Traditional Chinese and Western Medicine Hospital of Wuhan from March 2021 to March 2023, who received belimumab ≥ 5 times, were enrolled. Ten age- and sex-matched SLE patients with noutneuropsychiatric systemic lupus erythematosus (NPSLE) and normal controls were recruited to analyze potential biomarkers.

Diagnoses:

All patients were diagnosed with SLE based on the 2012 Systemic Lupus International Collaborating Clinics (SLICC) SLE classification criteria or the 2019 EULAR/ACR classification criteria. All SLE patients with CNS demyelinating syndromes were diagnosed by rheumatologists, neurologists, and radiologists.

Interventions:

These patients were administered belimumab combined with standard treatment (glucocorticoids and/or antimalarials and/or immunosuppressants [cyclophosphamide, mycophenolate, methotrexate, etc.]).

Outcomes:

Six patients were included in the study (100% female, mean [range] age at first demyelinating episode 42.8 [24–66] years). The most common extra-CNS features in these patients were rash, arthritis, alopecia, leukopenia, and hypocomplementemia. After Belimumab treatment, 3 of 6 (50%) patients achieved complete remission with decreased prednisone, 2 improvements, and 1 relapsed with uterine surgery. Compared with the baseline, 3.5 months post belimumab treatment, the disease activity score SLEDAI (21.5–5.5, P < .001), C3 and C4 increased, and extra-CNS symptoms improved rapidly. Moreover, The expression of lupus susceptibility gene PBX1 in CD19+ B cells was lowest in demyelinating syndromes with lupus patients compared with healthy volunteers and lupus patients without demyelination, and its relative expression negatively correlated with SLE disease activity.

Conclusion:

Belimumab could be an effective and safe option for the treatment of SLE demyelination. In addition, PBX1 might be a potential biomarker for the clinical diagnosis of lupus in patients with demyelinating syndrome.

Published: June 2023

The 2019 coronavirus disease (COVID-19) pandemic has affected different human populations since March 2020 and challenged healthcare systems, especially in chronic non-communicable diseases such as cancer. The present study aimed to evaluate the mortality, risk factors, and symptoms of cancer patients and control subjects, diagnosed with COVID-19 and admitted to intensive care unit (ICU). This retrospective, observational, non-randomized, controlled study of patients admitted to ICU was conducted between March and August 2020 in an Ecuadorian oncology center. Patient information collected from electronic medical records included sociodemographic information, clinical history, symptoms, laboratory test results, COVID-19 treatment, and discharge status. For patients with neoplasia, diagnosis, type, and status of cancer, as well as antineoplastic treatment received over the past month was also recorded. Descriptive statistics and multiple logistic regression were used to analyze the data. Statistical analysis was performed with SPSS (version 22.0) and R (version 4.1.3). In total, 79 adult COVID-19 patients were studied (40 with cancer and 39 controls). The total mean time until COVID-19 symptoms onset was 6.2 ± 3.5 days (5.3 ± 3.2 days in the cancer group vs 7.2 ± 3.6 days in the control group; P = .016) but no difference was observed in reported symptoms. All patients received an antibiotic treatment, but only 70% of the cancer group had antivirals (P < .001). Cancer patients had lower hemoglobin levels than controls (10.7 ± 2.8 vs 13.3 ± 1.7 g/dL; P < .001). In terms of mortality, not statistically significance difference was reported between groups. The study showed that high ferritin (Absolute Odds Ratio of 3.9; 95% CI 1.1–14.6) and mechanical ventilation (Absolute Odds Ratio of 4.9; 95% CI 1.3–18.6) were independent COVID-19 mortality risk factors. COVID-19 infection did not represent an increased risk of mortality in cancer patients, but elevated ferritin levels and the need for mechanical ventilation were identified as mortality risk factors.

New psychoactive substances (NPS) are emerging illegal substances or synthetic drugs that pose public health threats worldwide. This study was aimed at reporting the clinical characteristics of NPS and classical illicit substances used by patients who presented to the emergency room. We conducted a retrospective cohort study on patients with suspected illicit substance use who visited the emergency department (ED) with the suspicion of illicit substance use. We divided the patients into 4 groups based on the NPS testing results: NPS positive, NPS negative, NPS combined with classical illicit drugs (INPS), and subjects with negative testing results. The majority of patients in all groups were male. The NPS users were significantly younger than those with negative results on toxic testing (26.4 vs 37.5, P = .005 < 0.05). The heart rate of NPS users was significantly faster than that of the group with negative results of toxic testing (111.1 vs 93.5 beats per minute, P = .046). The heartbeats of INPS group were also significantly faster than those with a negative result in toxicology screen (119.6 vs 93.5 beats per minute, P = .024). Those who used classical illicit drugs combined with NPS had significantly higher palpitation than those with negative results of toxic testing (27.3% vs 3.1%, P = .017). Patients who were highly suspicious of NPS use were younger, had tachycardia, felt palpitations, and had fair oxygen saturation compared to patients who were negative for urine toxicity screening.

When the similarity of medicinal materials is high and easily confused, the traditional subjective judgment has an impact on the identification results. Use high-dimensional features to identify medicinal materials to ensure the quality of Chinese herbal concoction products and proprietary Chinese medicines. Objective: To study the identification algorithm of traditional Chinese medicinals (TCM) microscopic images based on convolutional neural network (CNN) to improve the objectivity and accuracy of microscopic image identification of TCM powders. Methods: Microscopic image datasets of 4 TCM powders sclereids of Rhizoma Coptidis, Cortex Magnoliae Officinalis, Cortex Phellodendri Chinensis, and Cortex Cinnamomi were constructed, and 400 collected images, as the model training and testing objects, were identified and classified by AlexNet model, VGGNet-16, VGGNet-19, and GoogLeNet model. Results: The average recognition accuracy in the tested microscopic image of AlexNet model, VGGNet-16, VGGNet-19, and the GoogLeNet model is 93.50%, 95.75%, 95.75%, and 97.50% correspondingly. Conclusion: The GoogLeNet model has a higher classification accuracy and is the best model to achieve real-time. Applying the CNN to the identification of microscopic images of TCM powders makes the operation of TCM identification simpler and the measurement more accurate while improving repeatability.

Published: June 2023

Background:

This study aimed to compare the clinical efficacy and safety of microwave ablation (MWA) and radiofrequency ablation (RFA) for the treatment of spinal metastases.

Methods:

A literature search was performed using the PubMed, Web of Science, and Cochrane Library databases according to the PRISMA statement (as of September 20, 2022). Two independent investigators screened articles based on the inclusion and exclusion criteria and included studies with primary outcomes of pain relief, tumor control, and complications. Article quality was assessed using the Risk Of Bias In Non-randomized Studies of Interventions tool.

Results:

Sixteen articles were finally included in this study, including 630 patients with spinal metastases, with ages ranging from 51.4 to 71.3 years. Of these, 393 (62.4%) underwent MWA and 237 (37.6%) underwent RFA. After MWA and RFA treatment, visual analog scale scores significantly decreased, and the local tumor control rates were all above 80%. Complications were reported in 27.4% of patients treated with MWA compared with 10.9% of patients treated with RFA.

Conclusion:

The results of this systematic review suggest that MWA alone or in combination with surgery and RFA in combination with other modalities may improve pain caused by primary tumor metastasis to the spine, and MWA alone or in combination with surgery may have better local tumor control. However, MWA appears to result in more major complications than RFA in combination with other treatment modalities.
Douyin as a source of information and education on humeral supracondylar fracture of children during the COVID-19 pandemic in Chinese Mainland: An observational study
Authors: Zhu Zhitao , Zheng Yan , Zhu Dongsheng
Published: June 2023

We aimed to investigate whether Douyin videos on pediatric humeral supracondylar fractures could be a useful source during the COVID-19 pandemic. A search was conducted using the term “humeral supracondylar fracture of children” on Douyin. The top 100 videos were selected based on view count. 74 was the final analysis, after excluding 26 videos for various reasons. First, the videos were classified into medical and the non-medical groups based on authorship. The medical team videos were about explanations or detailed surgical procedures directly related to child’s fracture. There were also non-medical videos, mostly about personal experiences and other things. The videos were then also divided into 2 groups abased on the year of COVID-19 pandemic. The number of views, content type, video duration and number of likes about the video were analyzed. Among the 74 videos included in this study, had a total of 19,647,988 views (median 205,129, range 7874–1,495,004). Compared to the medical group, the non-medical group had more views (P = .004), likes (P = .000), view ratio (P = .019), and video power index (P = .024). During the COVID-19 pandemic, views (P = .033), view ratio (P = .006), and video power index (P = .043) also increased. Douyin has been a valuable source of health information for patients during COVID-19 pandemic regarding the occurrence of humeral supracondylar fracture in children. Medical professionals and institutions should upload credible, informative videos and clear, high-quality, scientifically reviewed surgical footage of children with humeral supracondylar fracture. And the videos uploaded by medical professionals and filtered by Douyin’s staff appear to be necessary.

To evaluate the effects of aspirin in the primary prevention, we evaluated disability grades and mortality after ischemic/hemorrhagic stroke and myocardial infarction (MI). A retrospective nation-wide propensity score-matched cohort study was performed using the Korean National Health Information Database. From 3,060,639 subjects who were older than 55 and performed national health examinations in 2004 and 2005, we selected the aspirin group (N = 8770) was composed of patients who had received aspirin prior to cardiovascular events. Cox proportional hazards model was used to compare the acquisition times for neurologic disability grades and survival times between the aspirin and control groups. Only in hemorrhagic stroke, the severe neurologic disability risk was higher in the aspirin group (hazard ratio [HR], 1.21; 95% confidence interval [CI], 1.02–1.42). The aspirin group was associated with higher 90-day (HR, 1.33; 95% CI, 1.23–1.44) and long-term mortality risk (HR, 1.06; 95% CI, 1.03–1.10) after pooling 3 events. The old age was a strong risk factor for 90-day mortality in hemorrhagic stroke (50s: reference; 60s: HR 2.21, 95% CI 1.50–3.25; 70s: HR 3.63, 95% CI 2.48–5.30; 80s: HR 6.69, 95% CI 4.54–9.65; >90s: HR 11.28, 95% CI 6.46–19.70). Pre-aspirin use in cardiovascular events has detrimental effects on severe neurological disability in hemorrhagic stroke and short-/long-term mortality in 3 cardiovascular events. The use of aspirin for the primary prevention especially in the elderly should be very cautious because the old age is a strong risk factor for 90-day mortality after hemorrhagic stroke.

Authors: Kim Yoon Jung , Hwang So Yeong , Kim Hee-Soo
Published: June 2023

Background:

To evaluate the impact of abdominal binder (AB) use on postoperative shoulder pain in patients recovering from laparoscopic gynecologic surgery.

Methods:

This was a prospective randomized study conducted in a tertiary teaching hospital. Overall, 144 patients underwent laparoscopic gynecologic surgery. The postoperative use of an AB for 24 hours was added to the pulmonary recruitment maneuver.

Results:

Of 144 consenting patients, 72 patients each were allocated to the AB and control groups, respectively, and 14 patients were excluded. Finally, 130 patients were analyzed, with 68 in the AB group and 62 in the control group. There was no difference in the incidence of postoperative shoulder pain between the 2 groups (55.9% vs 56.5%, P = 1.000). The severity of the worst shoulder pain, measured using a numerical rating scale, did not differ between the 2 groups (Median [interquartile range] 2 [0–5] vs 2 [0–5]; P = .865). The severity of surgical site pain, pain and nausea medications, and the ambulation time were not different in the 2 groups.

Conclusion:

The use of an AB was not beneficial for postoperative shoulder pain following laparoscopic gynecologic surgery. Surgical site pain, ambulation time, and postoperative nausea and vomiting were not improved with the use of an AB.

Published: June 2023

To explore immune-related molecules that affect the prognosis of endometrial carcinoma (EC) using bioinformatic data mining. The expression data related to EC were downloaded from The Cancer Genome Atlas (TCGA) and Gene Expression Omnibus databases. After differential expression analysis, the intersection with immune related genes in the ImmPort database was used to obtain immune related differentially expressed genes (IRDEGs). The correlation between clinicopathological information and the prognosis of IRDEGs was further analyzed to obtain prognosis related differentially expressed immune genes (PRDEIG). Gene correlation analysis and Gene Set Enrichment Analysis (GSEA) enrichment analysis showed that PRDEIG was enriched in cancer-related functional pathways. We then analyzed the relationship between PRDEIG and immune cell infiltration, and further analyzed the mRNA and protein expression of PRDEIG in EC using TCGA and the human protein expression atlas (THPA) databases. After the intersection of the differential expression analysis results and immune-related genes, 4 IRDEGs were obtained: osteoglycin (OGN), LTBP4, CXCL12, and SPP1. After analyzing the relationship between 4 IRDEGs and clinicopathological parameters and prognosis of patients with EC, revealed that only OGN was not only related to tumor immunity, but also affected the prognosis of patients with EC. Gene correlation and GSEA enrichment of OGN were analyzed. The results showed that OGN was significantly enriched in 6 functional pathways: epithelial mesenchymal transition, KRAS signaling up, myogenesis, UV response, allograft rejection and apical junction. In addition, it was also found that OGN was significantly correlated with a variety of immune cells. The results of TCGA and THPA database showed that the mRNA and protein expression levels of OGN decreased in EC. OGN may affect the epithelial mesenchymal transformation (EMT) of tumor by affecting the infiltration of tumor immune cells.
