Hypercalcemia worsened after vitamin D supplementation in a sarcoidosis patient: A case report
Authors: Mio Kimito , Haruhara Kotaro , Shimizu Akihiro , Oshiro Kentaro , Kawai Rena , Ikeda Masato , Yokoo Takashi
Published: October 2022

Rationale:

There are many causes of hypercalcemia, with hyperparathyroidism and malignancy accounting for 90% of cases. Sarcoidosis and the intake of vitamin D supplements may also cause hypercalcemia, although the occurrence rate is low if only one is involved. We herein report a sarcoidosis patient who developed hypercalcemia after taking cholecalciferol (vitamin D supplement) for a year.

Patient concern:

A 62-year-old Japanese man presented with hypercalcemia and acute kidney injury along with symptoms of fatigue and appetite loss while being followed up for sarcoidosis.

Diagnoses:

We determined that a combination of cholecalciferol supplementation and sarcoidosis had led to hypercalcemia for several reasons. First, hypercalcemia had not been noted when this patient had first been admitted due to sarcoidosis-related respiratory failure several years earlier, which we presumed that was the highest sarcoidosis disease activity. Second, low serum 25-OH Vit.D3 and high 1,25-(OH)2 Vit.D3 levels were noted despite cholecalciferol supplementation for a year, suggesting that 1-α-hydroxylase overexpression caused by sarcoidosis accelerated the conversion from 25-OH Vit.D3 to 1,25-(OH)2 Vit.D3.

Interventions:

Although initially resistant to preservative management, the hypercalcemia promptly improved after starting corticosteroid treatment.

Outcomes:

Hypercalcemia and acute kidney injury were normalized after corticosteroid treatment.

Lessons:

We should be aware of patients’ medications, especially in patients with granulomatosis disease. The concomitant measurement of 25-OH Vit.D3 and 1,25-(OH)2 Vit.D3 levels is useful for determining the cause of hypercalcemia.

Published: October 2022

Esophageal cancer (ESCA), one of the most aggressive malignant tumors, has been announced to be the ninth most common cancer and the sixth leading cause of cancer-related death in the world. Chromobox family members (CBXs) are important epigenetic regulators which are related with the transcription of target genes. The role of CBXs in carcinomas has been reported in many studies. However, the function and prognostic value of different CBXs in ESCA are still largely unknown. In this article, we first performed differential expression analysis through several methods including Oncomine and Gene Expression Profiling Interactive Analysis. The results led us to determine the differential expression of CBXs in pan-cancer, especially ESCA. Then we evaluated the prognostic value of different CBX messenger RNA (mRNA) expression in patients with ESCA through the Kaplan–Meier plotter and the Human Protein Atlas database. In addition, we used cBioPortal to explore all genetic alterations and mutations in the CBXs in ESCA. Simultaneously, the correlation between its expression and the level of immune infiltration of ESCA was visualized by TIMER. Finally, the biological function of CBXs in ESCA is obtained through Biological Enrichment Analysis including gene ontology and Kyoto Encyclopedia of Genes and Genomes. The expression levels of CBX3/4/5 and CBX8 in ESCA tissues increased significantly and the expression level of CBX7 decreased through differential expression analysis. Additionally, CBX1 is significantly related to the clinical cancer stage and disease-free survival of ESCA patients. The high mRNA expression of CBX4 is related to the short overall survival of patients with esophageal squamous cell carcinoma, and the high mRNA expression of CBX3/7/8 is related to the short overall survival of patients with esophageal adenocarcinoma, indicating that CBX1/3/4/7/8 may be a potential prognostic biomarker for the survival of ESCA patients. Besides, the expression of CBXs is significantly related to the infiltration of a variety of immune cells, including six types of CD4-positive T-lymphocytes, macrophages, neutrophils, bursindependentlymphocyte, CD8-positive T-lymphocytes cells and dendritic cells in ESCA. Moreover, we found that CBXs are mainly associated with the inhibition of cell cycle and apoptosis pathway. Further, enrichment analysis indicated that CBXs and correlated genes were enriched in mismatch repair, DNA replication, cancer pathways, and spliceosomes. Our research may provide new insights into the choice of prognosis biomarkers of the CBXs in ESCA.
Association between CARD14 gene polymorphisms and psoriasis vulgaris in Hainan Han population based on exon sequencing: A case-control study
Authors: Msafiri Makene Antonia , Liu Jun-lin
Published: October 2022

Psoriasis is a serious non-communicable, chronic immune-inflammatory mediated disease affecting about 125 million people worldwide. Its effects go beyond skin manifestation. Through genome-wide association studies, the caspase recruitment domain family member 14 (CARD14) gene and other gene variants have been implicated to have an association with Psoriasis, and as we move towards individualized therapy the discovery of single nucleotide polymorphism (SNP) is of great importance. This study aimed to determine whether the CARD14 gene is a susceptible gene for psoriasis vulgaris. In this study, 101 psoriasis patients and 79 healthy controls were subjected to exome sequencing. The CARD14 gene regions upstream and downstream of 1kb were sequenced. SNP-based association analysis and haplotype-based association analysis were performed in SNPs with minimum allele frequency (MAF) greater than 1%. Bioinformatic methods were used to predict the impact of risk loci on gene function. A total of 32 polymorphisms were identified in this study, of which 3 SNPs (1 in exon and 2 in intron) were susceptible to psoriasis (P < .05, OR = 0.19~0.53, 95%CI = 0.05~0.70). Bioinformatics analysis showed that rs144475004 located on the exon led to an amino acid change from aspartate to histidine. On the other hand, results of haplotype-based association analysis showed that 2 haplotypes (CARD14-1 and CARD14-2) were protective haplotypes of the disease (P < .05, OR = 0.18~0.38, 95%CI = 0.05~0.88), the frequencies in healthy controls and patients was 6.96% and 1.49%, respectively. CARD14 gene is associated with susceptibility to psoriasis vulgaris in the Hainan Han population.

Authors: Bai Guoxin , Yi Junyu , Yu Yuanyuan , Du Hongxing
Published: October 2022

Background:

To investigate the effect of Anwei Qingyou formula on the clinical treatment of patients with peptic ulcer (PU) and its effect on the levels of epidermal growth factor (EGF) and prostaglandin E2 (PGE2).

Methodology:

Medical records of 83 patients with PU, treated in our hospital from January 2020 to January 2021, were retrospectively analyzed. Among them, 40 patients received conventional triple therapy (scheme I), that is, oral omeprazole, clarithromycin and amoxicillin, twice a day, and 43 patients received conventional triple therapy + Anwei Qingyou formula, taken orally twice a day (scheme II). The improvement of clinical symptoms, the quality of ulcer healing, clinical effectiveness and recurrence rate were analyzed after 4 weeks of treatment. Patients were followed up for six months.

Results:

After treatment with corresponding regimen, the total clinical effective rate of scheme II was 97.57% (42/43), which was significantly higher than 82.50% (33/40) of scheme I. Six-month follow-up results showed that the recurrence rate in scheme II patients was 4.65% (2/43), which was significantly lower than 20.00% (8/40) in the scheme I group (χ 2 = 5.479, 4.607, all P < .05). After one course of treatment, the levels of serum EGF and PGE2 in scheme II group were higher than those in scheme I group (P < .05).

Conclusion:

In combination with the conventional western medicine treatment, Anwei Qingyou formula administration in PU patients effectively improves the overall control of the disease and therapeutic effectiveness.

Published: October 2022

During the novel coronavirus disease (COVID-19) pandemic, emergency medical services (EMS) has borne a huge burden in transporting emergency patients. However, the protocol’s effect on identifying emergency patients who are likely to have COVID-19 is unknown. We aimed to evaluate the diagnostic accuracy of a prehospital COVID-19 screening protocol for EMS.

We conducted this population-based retrospective study in Nara Prefecture, Japan. The Nara Prefectural Government implemented a screening protocol for COVID-19 comprising the following symptom criteria (fever, cough, sore throat, headache, malaise, dysgeusia, or anosmia) and epidemiological criteria (contact history with confirmed COVID-19 cases or people with upper respiratory symptoms, or travel to areas with high infection rate). A patient meeting at least one criterion of each class was considered positive. We evaluated all 51,351 patients from the regional EMS database of the Nara Prefecture (emergency Medical Alliance for Total Coordination of Healthcare) who were registered from June 15, 2020 to May 31, 2021 and had results of COVID-19 reverse transcription polymerase chain reaction (RT-PCR) tests. We assessed the sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of this protocol. We also assessed how these outcomes changed by adding vital signs and conducted a 10-fold and 100-fold prevalence simulation.

The screening protocol was used for 246/51351 patients (0.5%). Among them, 31 tested positive after EMS transportation. This protocol’s sensitivity, specificity, PPV, and NPV were 40.8%, 99.6%, 12.6%, and 99.9%, respectively. With the addition of ≥2 vital signs (body temperature ≥37.5 °C, respiratory rate ≥20 breaths/minute, and oxygen saturation <90%), sensitivity and PPV changed to 61.8% and 1.0%, respectively, while NPV remained 99.9%. With a 10-fold and 100-fold increase in disease, the protocol PPV would be 59.0% and 94.3%, and NPV would be 99.1% and 90.7%, respectively, and with additional vital signs, PPV would be 8.9% and 53.1%, and NPV would be 99.4% and 93.2%, respectively.

This COVID-19 screening protocol helped enable EMS transport for patients with COVID-19 with a PPV of 12.6%. Adding other vital sign variables may improve its diagnostic value if the prevalence rate increases.

Authors: Joo Young , Moon JeeYoun , Lee Yoon Jin , Bang Yun-Sic , Yi Jungmin , Jang Jae Ni , Su Min-Ying , Kim Young Uk
Published: October 2022

Carpal tunnel syndrome (CTS) is correlated with increased intracarpal canal pressure (ICP). The effect of palmaris longus tendon (PLT) loading on ICP is documented in previous researches. PLT loading induces the greatest absolute increase in ICP. Therefore, to analyze the connection between the PLT and CTS, we newly made the measurement of the PLT cross-sectional area (PLTCSA). We assumed that PLTCSA is a reliable diagnostic parameter in the CTS. PLTCSA measurement data were acquired from 21 patients with CTS, and from 21 normal subjects who underwent wrist magnetic resonance imaging (W-MRI). We measured the PLTCSA at the level of pisiform on W-MRI. The PLTCSA was measured on the outlining of PLT. The two different cutoff values in the analysis were determined using receiver operating characteristic (ROC) analysis. The mean PLTCSA was 2.34 ± 0.82 mm2 in the normal group and 3.97 ± 1.18 mm2 in the CTS group. ROC curve analysis concluded that the best cutoff point for the PLTCSA was 2.81 mm2, with 76.2% sensitivity, 71.4% specificity, and area under the curve of 0.88 (95% CI, 0.78‐0.98). PLTCSA is a sensitive, new, objective morphological parameter for evaluating CTS.
Abnormal uterine position during pregnancy secondary to abdominal surgery: Two case reports
Authors: Li Huanxi , Wu Quanfeng , Wei Wei , Lin Xueyan , Zhang Xueqin
Published: October 2022

Rationale:

The umbilical cord is the way to exchange gas, supply nutrients, excrete metabolized. Thrombosis of the umbilical cord leads to fetal hypoxia, which jeopardizes fetal health and can cause fetal death. Umbilical vessel thrombosis, which is rarely reported, is difficult to detect prenatally.

Patient concerns:

Both individuals included in this study had a history of abdominal operation before pregnancy. The abnormal uterine position demonstrated in the first patient developed secondary to adhesions between the anterior bladder wall and lower segment of the uterus. As the uterus increased in size in proportion with the gestational age, the uterine body continued to enlarge even as the lower uterine segment remained fixed by the adhesions, which resulted in cervical displacement. In comparison, the abnormal uterine position in the second patient was due to a rare case of uterine incarceration developed.

Diagnosis:

Both cases were diagnosed as abnormal uterine position during pregnancy secondary to abdominal surgery.

Interventions:

The first patient underwent a cesarean section at 33 weeks and 5 days age of gestation for pregnancy complications. The second patient performed a cesarean section at 37 weeks age of gestation.

Outcomes:

Due to reasonable treatment, the 2 cases achieved good maternal-infant outcomes.

Conclusion:

Abnormal uterine position during pregnancy should be considered seriously, because it can affect the prognosis of the mother and child. When appropriate, a cesarean section is an effective method for terminating such pregnancies. During cesarean section, a longitudinal skin incision may be more beneficial in avoiding secondary injuries. However, the choice of uterine incision should be adjusted for each patient. Care should be given to prevent postpartum hemorrhage.
The role of hepatic reserve in the mortality of cirrhotic patients with small hepatocellular carcinoma receiving radiofrequency ablation
Authors: Hung Tsung-Hsing , Tsai Chih-Chun , Lee Hsing-Feng
Published: October 2022

Although radiofrequency ablation (RFA) is considered a curative treatment for early stage small hepatocellular carcinoma (HCC), the long-term prognosis is suboptimal. The major complications in cirrhotic patients are usually related to poor prognosis and include esophageal variceal bleeding, ascites, and hepatic encephalopathy. This study aimed to evaluate the role of liver reserve on mortality after RFA for early stage HCC among cirrhotic patients, according to the presence of the number of complications. The Taiwan National Health Insurance Database was used to identify 2389 cirrhotic patients with treatment-naïve HCC (<3 cm) undergoing RFA hospitalized between January 1, 2010 and December 31, 2013. Of these, 594 patients had concurrent or a history of cirrhotic-related complications. The 1-year and 3-year survival rates in the cirrhotic patients with complications were 78.5% and 39.8%, respectively, and those in the patients without complications were 92.7% and 65.9% (P < .001), respectively. Age (hazard ratio [HR] 1.03, 95% confidence interval [CI] 1.02–1.04, P < .001) and cirrhotic-related complications (HR 2.65, 95% CI 2.22–3.16, P < .001) significantly increased 3-year mortality. The HR of mortality in patients with 1, 2, or 3 complications compared to those without complications were 2.35 (95% CI 1.92–2.88), 3.27 (95% CI 2.48–4.30), and 4.63 (95% CI 2.82–7.62), respectively (all P < .001). In cirrhotic patients with early stage HCC undergoing RFA, poor liver reserve correlates with poor outcome. The presence or history of three cirrhotic-related complications increased 3-year mortality 4-fold.

Published: October 2022

Introduction:

Both acupuncture and moxibustion have been used for thousands of years in China for diverse conditions. But there are few reports on their combined effect in managing benign prostatic hyperplasia (BPH). To answer this question, we designed a prospectively study and the present protocol described details of this randomized controlled trial (RCT).

Methods:

In this RCT, an estimated number of 200 patients with BPH will be enrolled from Shanghai Fourth People’s Hospital, China. They will be assigned to either the combined therapy group or the conventional western medicine group in a ratio of 1:1. The International Prostate Symptom Score (IPSS) will be assessed as the primary outcome, other parameters, including the post-voiding residual urine volume, maximum flow rate (Qmax), and average flow rate (Qave), voiding time, and time to maximum flow, are secondary outcomes.

Discussion:

Results of this study will provide the theoretical basis for clinicians to select combined therapy or conventional western medicine treatments for BPH patients based on the efficacy of these therapies.

Effectiveness and safety of repetitive transcranial magnetic stimulation on memory disorder in stroke: A protocol for systematic review and meta-analysis
Authors: Xie Haihua , Xiong Dan , Zhu Pan , Li Hao , Zhang Hong , Tan Jie , Zhao Ning
Published: October 2022

Background:

Approximately 23% to 55% of patients have memory impairments with a greatly negative effect on daily life 3 months after stroke. Repetitive transcranial magnetic stimulation (rTMS) has been widely used in the rehabilitation of stroke as it is safe, painless, and noninvasive. Moreover, few studies have investigated the effect of rTMS on poststroke memory disorder (PSMD). However, the efficacy of rTMS is not consistent and the optional stimulation frequency is unclear. Therefore, this protocol aims to evaluate the clinical effect and safety of rTMS on PSMD by analyzing results from randomized controlled trials.

Methods:

Search strategies will be performed on seven databases: PubMed, EMBASE, CENTRAL, Chinese Biomedical Literature Database (CBM), Chinese National Knowledge Infrastructure (CNKI), Wan Fang, and Technology Periodical Database (VIP). Only randomized controlled trials registered before August 2021 will be included. Additionally, the language will be limited to English or Chinese. For the outcome, we will focus on the Rivermead Behavioral Memory Test. Additionally, the Montreal Cognitive Assessment, Mini-mental State Examination, Modified Barthel Index, and advent events will be included. Two authors will independently select the study, extract data, and assess quality. Moreover, disagreements will be resolved by the third author. STATA 14 and Review Manager 5.4 will be used to perform the analysis. We will evaluate bias risk in accordance with the Cochrane Handbook for Systematic Reviews of Interventions. To assess the quality of evidence, the Grading of Recommendations Assessment, Development, and Evaluation method will be employed.

Results:

This study will provide a comprehensive analysis of the current evidence on rTMS for PSMD.

Conclusion:

A reliable conclusion regarding whether rTMS is an effective and safe intervention for patients with PSMD and the effect of stimulation frequency and sham stimulation will be provided. This study will provide new insights for TMS in treating PSMD, and offer appropriate treatmentoptions to patients and clinicians.

Authors: Luo Xuexing , Zhang Zheyu , Zheng Zhong , Ye Qian , Wang Jue , Wu Qibiao , Huang Guanghui
Published: October 2022

Background:

The efficacy of art therapy as an adjuvant treatment for schizophrenia remains inconclusive, and variation in the effects of art therapy on schizophrenia by the type of schizophrenia, severity of schizophrenia, type of art therapy, follow-up duration, or different populations has never been systematically assessed. The objective of this study is to systematically evaluate the effects of art therapy on schizophrenia and to determine whether there are some potential influencing factors affecting the effects of art therapy.

Methods:

Seven online databases will be searched from their inception until June 30, 2022. All the relevant randomized clinical trials (RCTs) comparing art therapy plus standardized treatment versus standardized treatment alone for schizophrenia will be selected and assessed for inclusion. The Cochrane risk-of-bias tool will be used to evaluate the methodological quality of the included RCTs. Review Manager 5.4 will be used to analyze all the data obtained. Mental health symptoms are defined as the primary outcome, and the secondary outcomes include the Global Assessment of Functioning score, quality of life, functional remission, and the level of self-esteem. Subgroup analyses will be performed based on the type of schizophrenia, severity of schizophrenia, type of art therapy, follow-up duration, or different populations.

Results:

The results will be published in a peer-reviewed journal.

Conclusions:

This updated systematic review and subgroup meta-analysis will evaluate the effects of art therapy as adjunctive treatment to standardized treatment in patients with schizophrenia and determine whether there are some potential confounding variables affecting the effects of art therapy on the outcomes of schizophrenia patients, thus strengthening the evidence base for the clinical application of this combination therapy for schizophrenia.

Published: October 2022

Background:

To explore the association between Angiotensin Converting Enzyme (ACE) insert(I)/defect(D) gene polymorphism and the susceptibility to idiopathic pulmonary fibrosis (IPF).

Methods:

Searching PubMed, EMbase, CENTRAL, MEDLINE, CBM, China National Knowledge Infrastructure, WanFang Database and VIP Chinese Science database through a computer and collect the literature from China and foreign countries published before January 22, 2022. Screen the literatures and extract data such as first author, year of publication, diagnostic criteria and gene frequency, and draw a funnel chart and perform Begg’s Test and Egger’s test to evaluate publication bias. The influence analysis was performed for heterogeneous results and at the same time, the trial sequential analysis (TSA) was also conducted to confirm the robustness of the meta-analysis results. Registration number: CRD42021259341.

Results:

There were a total of 4 literatures (4 studies conducted in the Chinese Han population), and a total of 292 IPF patients and 351 healthy controls were included in this study. The results showed that in the Chinese Han population, the ACE I/D gene polymorphism was associated with the susceptibility of IPF (D vs I: [odds ratio, OR] = 0.53, 95% confidence interval [95%CI] [0.42, 0.67], P < .00001; DD vs II: [OR] = 0.37, 95%CI [0.24, 0.57], P < .00001; DD vs II + ID:[OR] = 0.30, 95%CI [0.21, 0.43], P < .00001), and the angiotensin II (Ang Ⅱ) level of IPF patients was higher than that of the control group (mean difference [MD] = 14.29, 95%CI [11.20,17.37], P < .00001).The TSA also confirmed that D allele was closely related to the susceptibility of IPF.

Conclusion:

In the Chinese Han population, the D allele of the ACE I/D gene polymorphism is associated with the susceptibility of IPF.
Anterior segment pars plana vitrectomy combined with posterior capsulorhexis, phacoemulsification and trabeculectomy in treatment of medically uncontrolled acute primary angle-closure glaucoma: A retrospective study
Authors: Qu Jie , Tian Zhen , Li Xin , Zhang Yong
Published: October 2022

To explore the clinical efficacy of quadruple surgery (anterior segment pars plana vitrectomy + phacoemulsification + posterior capsulorhexis + intraocular lens (IOL) implantation + trabeculectomy) and dual surgery (phacoemulsification + IOL implantation + trabeculectomy) to treat medically uncontrolled acute primary angle-closure glaucoma (APACG). The clinical data of 44 patients (45 eyes) with APACG treated in the Department of Ophthalmology of Taihe Hospital were retrospectively analyzed. They were divided into 2 groups based on quadruple surgery and dual surgery. There were 20 patients (20 eyes) underwent quadruple surgery in group A. And there were 24 patients (25 eyes) dual surgery in group B. The changes in intraocular pressure (IOP), visual improvement, and complications were observed between the 2 groups preoperatively and 1 month, 3 months, and 6 months postoperatively. Preoperative best corrected visual acuity (BCVA) was the influencing factor of postoperative BCVA at 1 month, 3 months and 6 months. Before surgery, the mean IOP of group A was significantly higher than that of group B (P < .001), and no significant difference was found in the BCVA, age, gender, eyes, axial length (AL), anterior chamber depth (ACD) (P
BCVA = 0.12, P
age = 0.76, P
eyes = 0.20, P
gender = 0.37, P
AL = 0.94, P
ACD = 0.08). On comparison at postoperative 1week, there was no significant difference in the IOP and BCVA between the 2 groups (P
IOP = 0.64, P
BCVA = 0.66). The mean IOP of group A was significantly lower than that of group B 1 month, 3 months, and 6 months postoperatively (P
1month = 0.002, P
3months < 0.001, P
6months < 0.001). The degree of visual acuity recovery was significantly higher in group A at 1 month, 3 months, and 6 months postoperatively (P
1month = 0.03, P
3months = 0.02, P
6months = 0.02). During treatment, the incidence of complications in group B was significantly higher than that in group A (P < .01). The clinical efficacy of anterior segment pars plana vitrectomy combined with posterior capsulorhexis, phacoemulsification, and trabeculectomy elicits clinical safety in treating medically uncontrolled APACG. It has remarkable effects and leads to a significant decrease in the occurrence of complications.
Association between intraoperative fluid overload and postoperative debridement in major sacrum tumor resection: A propensity score matching study
Authors: Li Qi , Dong Sen , Yan Taiqiang , Zhao Hong
Published: October 2022

Intra-aortic balloon occlusion (IABO) is used to reduce intraoperative bleeding and facilitate successful sacrum tumor resection. Up to 20% of patients experience postoperative wound healing problems, but the risk factors related to this complication have not been clearly defined. The anesthetic database of Peking University People’s Hospital, Beijing, China, was searched for all patients (aged 14‐70 years old) who underwent sacrum tumor surgery with the application of IABO from 2014 to 2017. Data from 278 patients with an aortic occlusion duration of 72 ± 33 minutes were collected. Fifty-six patients required postoperative debridement because of wound infection. The independent risk factor identified by logistic regression was fluid excess (calculated as volume infused minus blood loss and urine output divided by body weight [kg]), and decision tree analysis revealed that the cutoff point for fluid excess was 38.5 mL/kg. Then patients were then divided into high fluid excess group (fluid excess > 38.5 mL/kg) and low fluid excess group (fluid excess ≤ 38.5 mL/kg) and 91 pairs of patients were generated through propensity score matching (PSM). Fluid excess was significantly higher in the high fluid excess group (46 vs 30 mL/kg, P < .001), and more patients required postoperative debridement than in the low fluid excess group (24 (26.3%) vs 12 (13.1%), P < .001). In this retrospective PSM study on sacrum tumor resection, fluid overload was related to postoperative debridement and further studies are needed to improve the clinical prognosis.
Gunao-Yizhi decoction combined with donepezil for vascular dementia: A systematic review and meta-analysis
Authors: Hu Yibin , Zhang Lijuan , Guan Xiuju , Hou Hanru , Bi Shuyue , Liu Changning , Li Mingxiang , Wang Kangfeng
Published: October 2022

Background:

Gunao-Yizhi decoction has the effects of supplementing intelligence, strengthening marrow, resolving phlegm, and reducing turbidity. It is clinically used for the treatment of vascular dementia (VaD). However, there is still a lack of systematic evaluation of its efficacy and safety. This review conducted a systematic review of the current evidence on the efficacy and safety of Gunao-Yizhi decoction combined with donepezil for VaD.

Methods:

China National Knowledge Infrastructure (CNKI), Wanfang database (Wanfang), Chinese Science and Technology Periodical Database (VIP), China Biology Medicine disc (CBM), MEDLINE, EMBASE, and Cochrane Library were searched for randomized controlled trials on Gunao-Yizhi decoction combined with donepezil for VaD. RevMan 5.3 software was used for data analysis.

Results:

Twelve studies were obtained, including 1036 patients. Compared with donepezil alone, meta-analysis showed that Gunao-Yizhi decoction combined with donepezil could improve clinical efficacy, mini-mental state examination (MMSE) score, Hasegawa dementia scale (HDS), increase the level of superoxide dismutase (SOD) in serum, and reduce the level of malonaldehyde dismutas (MDA) in serum. The GRADE system was adopted to evaluate the outcome index. Clinical efficiency and the MMSE score were evaluated as very-low-quality evidence. HDS score, serum SOD level, and serum MDA level were evaluated as low-quality evidence.

Conclusion:

Gunao-Yizhi decoction combined with donepezil has a significant prevalence in the treatment of vascular dementia, with no increase in adverse events. Gunao-Yizhi decoction can be recommended for routine use in the treatment of VaD.
The baseline and repeated measurements of DBP to assess in-hospital mortality risk among critically ill patients with acute myocardial infarction: A retrospective cohort study
Authors: Huang Sulan , Luo Yanlan , Liang Li , Guo Ning , Duan Xiangjie , Zhou Quan , Ge Liangqing
Published: October 2022

Changes in diastolic blood pressure (DBP) are common in patients with acute myocardial infarction (AMI). The relationship between the dynamic change of DBP and in-hospital mortality among patients with AMI remains unclear. This study aimed to explore the importance of DBP during disease development among patients with AMI. We performed a retrospective cohort study involving patients from the Medical Information Mart for Intensive Care III database, which included > 40,000 patients admitted to the intensive care unit (ICU). Overall, 3209 adult AMI admissions were identified. We extracted the clinical and laboratory information in the patients with AMI. Cox proportional hazards models were used to evaluate the prognostic values of baseline DBP. We used the generalized additive mixed model (GAMM) to compare trends in DBP over time among survivors and non-survivors, after adjusting for potential confounders. During the ICU stay, 189 patients died (mortality rate, 6.36%). The age of each non-survivor together with the variations in DBP over time from admission to the time of death is of great importance to the scientific community. Cox multivariable regression analysis displayed that after adjusting for confounding factors, ascended baseline DBP was an important hazard factor for hospital deaths (hazard ratio, 1.02; 95% confidence interval, 1.01–1.03; P = .003). Based on GAMM, DBP in the death group was markedly lower than that of the surviving group. Moreover, the difference between the two groups showed an increasing trend within 3 days after ICU admission. After adjusting for various variables, the results were stable. DBP significantly contributed to in-hospital mortality among patients with AMI. There was a nonlinear correlation between baseline DBP and in-hospital mortality among patients with AMI, and the DBP of the non-survivors decreased within the first 3 days after ICU admission.

Published: October 2022

Background:

Studies have found that pre-service teachers commonly face stressful circumstances that prevent them from completing their academic tasks effectively. In terms of psychological factors and interventions, pre-service history teachers in Nigeria are the least studied group. The objective of this study was to investigate the effect of stress management coaching among Nigerian pre-service history teachers.

Methods:

The research participants consisted of a randomized sample of 109 pre-service history teachers from Nigerian public higher education institutions (55 pre-service history teachers composed the stress management coaching group while 54 pre-service history teachers composed the waitlist control group). The stress management coaching for the pre-service history teachers was guided by a coaching manual created using the theoretical framework of rational emotive behavior coaching.

Results:

Pre-service history teachers who participated in stress management coaching showed significantly reduced stress levels at the post-test and follow-up. There was an interaction effect between group and time on the stress of pre-service history teachers.

Conclusion:

The study suggests that pre-service history teachers can benefit from a stress management coaching intervention that uses the rational emotive behavior coaching approach. The development of this form of stress management coaching program on a large scale among pre-service history teachers could prove beneficial to their academic and personal success. Studies may be conducted in the future to examine the stress of history teachers in colleges and the efficacy of stress management coaching.
Astrocytoma with myelin oligodendrocyte glycoprotein antibody associated encephalomyelitis: A case report
Authors: Zhong Guanghong , Zhang Jia , Liu Xi , Yang Shaoming , Gu Hongli
Published: October 2022

Background:

Demyelination is similar with malignancy in clinical symptoms. Magnetic resonance imaging (MRI) is an important auxiliary examination in the diagnosis of demyelinating diseases and malignancy. Since MRI and symptoms can be difficult to distinguish demyelination from malignancy, other auxiliary examinations, such as demyelinating disease-specific antibodies, play an important role in distinguishing them. Previous studies have reported demyelinating disease-specific antibodies in patients with malignancy. What’s more, it is more difficult to confirm the diagnosis when the malignant tumor co-occurs with demyelinating diseases, which has never been reported in previous studies. We report the diagnosis of myelin oligodendrocyte glycoprotein antibody associated encephalomyelitis (MOG-EM) in a patient who had astrocytoma for several years.

Case presentation:

Patient’s concerns and diagnoses: our case report records a 49-year-old woman with astrocytoma for more than 4 years, who recently developed the symptoms of MOG-EM, including dizziness, vomiting, and vision loss. This astrocytoma patient was diagnosed with MOG-EM according to comprehensive evidence, including MRI, visual evoked potential (VEP), serum myelin oligodendrocyte glycoprotein antibody (MOG-IgG), and therapeutic effect. Interventions and outcomes: this patient was diagnosed with astrocytoma by surgical biopsy 4 years earlier. This patient has been treated with tumor resection, postoperative radiation treatment and chemotherapy. After treatment, the patient was left with right limb weakness while other symptoms were improved. Recently, the intravenous steroid agent was used to treat this patient after being diagnosed with MOG-EM. Dizziness, vomiting, and vision loss have gone into remission. This patient did not relapse in 7 months after discharge. This patient is still being followed up at the outpatient clinic. And the patient will next be treated with azathioprine.

Conclusions:

In previous studies, polyclonal antibody has been found in cancer patients, such as aquaporin-4 and MOG-IgG in astrocytoma patients. But the case of our study finds that astrocytoma can coexist with MOG-EM. Therefore, MOG-EM should not be excluded easily in astrocytoma patients when the relative antibody of encephalomyelitis is positive. What’s more, it reminds us that the pathogenesis of MOG-EM might be related to astrocytoma.

Buyang Huanwu Decoction, a traditional Chinese medicine decoction, is widely used to treat spinal cord injury in China. However, the underlying mechanism of this decoction in treating spinal cord injury is unclear. This study used network pharmacology and molecular docking to examine the pharmacological mechanism of Buyang Huanwu Decoction in prevention and treatment of spinal cord injury. The active compounds and target genes of Buyang Huanwu Decoction were collected from the Traditional Chinese Medicine Systems Pharmacology and the SwissTargetPrediction Database. The network diagram of ”traditional Chinese medicine compound target“ was constructed by Cytoscape software. Genetic data of spinal cord injury were obtained by GeneCards database. According to the intersection of Buyang Huanwu Decoction’s targets and disease targets, the core targets were searched. The protein-protein interaction network were constructed using the STRING and BisoGenet platforms. Meanwhile, gene ontology enrichment and Kyoto encyclopedia of genes, and genome pathway were performed on the intersection targets by Metascape. Molecular docking technology was adopted to verify the combination of main components and core targets. A total of 109 active compounds and 5440 prediction targets were screened from 7 Chinese herbal medicines of Buyang Huanwu Decoction, with 98 active components and 49 related prediction targets being strongly linked to Spinal Cord Injury. By studying protein-protein interaction network, a total of 8 core proteins were identified, primarily interleukin-6, tumor protein P53, epidermal growth factor receptor, and others. Positive regulation of kinase activity regulation of reaction to inorganic chemicals are the basic biological processes. Buyang Huanwu Decoction cures Spinal Cord Injury primarily by moderating immunological inflammation, apoptosis, and oxidative stress, which involves the cancer pathway, the HIF-1 signaling pathway, the p53 signaling pathway, the MAPK signaling pathway, and so on. The results of molecular docking demonstrated that the primary components could attach to the target protein effectively. Finally, the mechanism of Buyang Huanwu Decoction in the treatment of spinal cord injury through multicomponent, multitarget, and multichannel was deeply explored. And it offers new ideas and directions for future research on the mechanism of the treatment of spinal cord injury.

Introduction:

Hyperosmolar solutions are prescribed in neurosurgery patients to provide satisfactory intraoperative brain relaxation and to lower cerebral injuries related to surgical retractors. Mannitol is traditionally considered as the first-choice solution for brain relaxation in neurosurgery patients. Hypertonic sodium lactate infusion was reported to provide a higher and longer osmotic effect compared to mannitol in severely brain-injured patients and to prevent impaired cerebral energetics related to brain injuries. To date, the clinical effectiveness of hypertonic sodium lactate infusion has never been studied in neurosurgery patients. The hypothesis of the study is that hyperosmolar sodium lactate infusion may provide satisfactory intraoperative brain relaxation in patients undergoing scheduled craniotomy for supratentorial brain tumor resection.

Methods and analysis:

We designed a phase II randomized, controlled, double-blind, single-center pilot trial, and aim to include 50 adult patients scheduled for craniotomy for supratentorial brain tumor resection under general anesthesia. Patients will be randomized to receive either mannitol (conventional group) or hypertonic sodium lactate (intervention group) infusion at the time of skin incision. Brain relaxation (primary outcome) will be assessed immediately after opening the dura by the neurosurgeon blinded to the treatment allocated using a validated 4-point scale. The primary outcome is the proportion of satisfactory brain relaxation, defined as brain relaxation score of 3 or 4.

Ethics and dissemination:

This study was approved by the Ethics Committee (Comité de Protection des Personnes Est III) and authorized by the French Health Authority (Agence Nationale de Sécurité des Médicaments, Saint-Denis, France). The University Hospital of Besancon is the trial sponsor and the holder of all data and publication rights. Results of the study will be submitted for publication in a peer-review international medical journal and for presentation in abstract (oral or poster) in international peer-reviewed congresses.

Registration:

The trial is registered with ClinicalTrials.gov (Identifier: NCT04488874, principal investigator: Prof Guillaume Besch, date of registration: July 28, 2020).

Published: October 2022

A retrospective observational study The purpose of this study was to characterize the learning curve for a single level unilateral laminectomy and bilateral decompression in lumbar spinal stenosis using a learning curve cumulative summation test. Unilateral laminectomy and bilateral decompression for lumbar spinal stenosis proposes a potential benefit with minimizing surgery-related instability compared to traditional bilateral laminectomy, by preserving posterior stabilizing structures and contralateral facet joint and neural arch. Due to a narrow surgical corridor, it is considered to exhibit a steep learning curve as other types of minimally invasive procedures. However, there are few reports available regarding learning curve of unilateral laminectomy and bilateral decompression. The learning curve of a single surgeon performing single level unilateral laminectomy and bilateral decompression was assessed using learning curve cumulative summation test analysis. The surgeon had minimal experience in open decompressive laminectomy but no previous experience in unilateral laminectomy and bilateral decompression. Procedure success was defined as an operation time less than 75 minutes. Surgery related complications were recorded. Total 194 consecutive patients, who underwent primary single level unilateral laminectomy and bilateral decompression by a single spine surgeon, were included. The mean operative time for unilateral laminectomy and bilateral decompression was 64.6 ± 23.6 minutes. The mean operative time in the early learning period (≤29th case) was 80.6 ± 20.9 minutes, and that in the late learning period (after 29th case) was 61.8 ± 22.7 minutes, respectively. The overall complication rate was 13.9%. Majority of complications occurred in the early learning period. The learning curve cumulative summation test signaled competency for unilateral laminectomy and bilateral decompression at the 29th operation, indicating that the surgeon reached the competent level. In addition, based on the cumulative summation test, the surgeon seemed to maintain his competency for the procedure. This study showed that surgical experience reduced the operation time and surgery related complications. For inexperienced surgeon to achieve an acceptable outcome in unilateral laminectomy and bilateral decompression, minimum 30 cases of unilateral laminectomy and bilateral decompression are required to reach competent level of surgery.
Hypoglycemia Management Using a Bundled Care Approach
Authors: Mattathil Reni
Published: October 2022

Background:

Hypoglycemia is a leading cause of preventable hospitalization, and can increase morbidity, mortality, and length of hospital stay. Up to 35% of diabetic patients experience severe hypoglycemia during hospitalization; this concerns veterans, as 25% have been diagnosed with diabetes.

Local Problem:

A medical-surgical unit in a Veterans Affairs facility saw increased hypoglycemic episodes, with 26.8 episodes per 1000 patient days. Staff noted knowledge deficits with how to manage hypoglycemia episodes.

Methods:

A pre-/post-implementation quality improvement project was conducted over 8 weeks.

Interventions:

An implementation bundle was used to improve hypoglycemic episodes, including patient and staff education, coordination between meal delivery and insulin coverage, and developing a hypoglycemia protocol.

Results:

Hypoglycemia rates significantly decreased to 10.27 per 1000 patient days (P = .001), and occasions where insulin was given with food increased significantly to 76.2% (P < .001).

Conclusions:

A bundled approach was effective in decreasing hypoglycemia episodes and improved consistent management of hypoglycemia.
