Published: December 2023

Post-cardiac arrest brain injury constitutes a significant contributor to morbidity and mortality, leading to cognitive impairment and subsequent disability. Individuals within this patient cohort grapple with uncertainty regarding the potential advantages of extracorporeal life support (ECMO) cannulation. This study elucidates the neurological outcomes and quality of life of post-cardiac arrest patients who attained spontaneous circulation and underwent ECMO cannulation. This is a retrospective case study within a local context, the research involved 32 patients who received ECMO support following an intrahospital cardiac arrest with return of spontaneous circulation (ROSC). An additional 32 patients experienced cardiac arrest with ROSC before undergoing cannulation. The average age was 41 years, with the primary causes of cardiac arrest identified as acute coronary syndrome (46.8%), pulmonary thromboembolism (21.88%), and hypoxemia (18.7%). The most prevalent arrest rhythm was asystole (37.5%), followed by ventricular fibrillation (34.4%). The mean SOFA score was 7 points (IQR 6.5–9), APACHE II score was 12 (IQR 9–16), RESP score was −1 (IQR −1 to −4) in cases of respiratory ECMO, and SAVE score was −3 (IQR −5 to 2) in cases of cardiac ECMO. Overall survival was 71%, and at 6 months, the Barthel score was 75 points, modified Rankin score was 2, cerebral performance categories score was 1, and the SF-12 had an average score of 30. Notably, there were no significant associations between the time, cause, or rhythm of cardiac arrest and neurological outcomes. Importantly, cardiac arrest is not a contraindication for ECMO cannulation. A meticulous assessment of candidates who have achieved spontaneous circulation after cardiac arrest, considering the absence of early signs of poor neurological prognosis, is crucial in patient selection. Larger prospective studies are warranted to validate and extend these findings.
The effect of music therapy on tinnitus: A systematic review
Authors: Niu Yunlian , You Yijie
Published: December 2023

Objectives:

Tinnitus is a common otological symptom affecting almost all aspects of life, especially the quality of daily life. The present study aims to analyze music therapy effect on tinnitus patients. This paper mainly analyzes 3 kinds of music therapy: Heidelberg model of music therapy (HMOMT), standard music therapy (SMT), and tailor-made notched music training (TMNMT). To provide a reference for the follow-up treatment of tinnitus, whether to take and what kind of music therapy.

Method:

A systematic literature search was performed in PubMed, Cochrane Library, EMBASE, Web of Science, and MEDLINE to obtain potential studies from their inception to May 2023 in all languages. Two researchers independently screened the studies, extracted data, and assessed the quality of the included studies. We included all randomized and non-randomized controlled trials that used music therapy to treat patients with tinnitus. We used fixed-effects and random-effect models to analyze data based on the heterogeneity results. The data analysis was performed by using Stata 12.0.

Results:

A total of 19 studies with 904 cases were included. Compared with before treatment, music therapy significantly reduces the tinnitus questionnaire score and tinnitus handicap inventory score. HMOMT, SMT, and TMNMT all significantly decrease tinnitus scores. Although the order of effectiveness of the 3 drugs is TMNMT > SMT > HMOMT, there is no statistical significance (P > .5).

Conclusion:

This meta-analysis of accumulated clinical trial data suggests that music therapy can relieve tinnitus symptoms and loudness. Among music therapies, SMT is recommended first for tinnitus based on cost, efficacy, and convenience. At the same time, TMNMT and HMOMT can be used as alternative therapies for specific cases.
Type 1 diabetes mellitus: Roles of neutrophils in the pathogenesis
Authors: Obeagu Emmanuel Ifeanyi , Obeagu Getrude Uzoma
Published: December 2023

Circulating neutrophil counts are reduced both in healthy autoantibody-positive individuals and in patients with type 1 diabetes, which may be related on cell-specific autoimmunity. This paper was written to give an update on roles of neutrophils in the pathogenesis of type 1 diabetes mellitus. Different research search engines like PubMed Central, Scopus, Web of Science, Researchgate, Google Scholar etc were utilised for writing this paper. A drop in blood neutrophil counts in type 1 diabetes may be caused by decreased neutrophil generation and maturation, tissue maintenance, consumption, or peripheral damage. Neutrophil count variations between studies may be explained by results from various stages of diabetes or by ethnic groups. Neutrophils can induce type 1 diabetes by colonizing pancreatic islets and interacting with other immune cells, according to exciting findings that shed new light on their role in the pathogenesis of the disease. Knowing more about the function of neutrophils in the pathogenesis of type 1 diabetes will help in early diagnosis, treatment, and even prevention of the disease.

Authors: Chen Gao , Qin Chun-Jun , Wu Meng-Zheng , Liu Shu-Shu , Liu Li , Liu Jian-Ying
Published: December 2023

The aim of the present study was to analyze the clinical features, treatments, and short-term prognoses of 18 patients with novel coronavirus pneumonia (NCP) in order to provide reference for further clinical prevention and control of the epidemic. From January 29 to February 29, 2020, data from 18 patients with NCP who were positive for the 2019 novel coronavirus nucleic acid test were collected, and their clinical manifestations, laboratory tests, imaging features, and treatment protocols were analyzed retrospectively. From among the 18 patients with NCP, 9 (50%) were imported cases and 9 (50%) had contact histories with confirmed adult patients. Clinical classification was mainly of the normal type (16 cases, 88.9%). Fever and cough were common clinical symptoms, and the main laboratory indices were lymphocytopenia and leukocytopenia. The main imaging findings yielded ground-glass opacity in 12 cases (66.7%) and patchy opacity in 9 cases (50%). All 18 patients were treated with antiviral therapy and targeted treatment in accordance with their symptoms, returned negative nucleic acid tests (9–23 days) after their treatment, and were cured and discharged by March 5, 2020. During the early stages in Deyang, most patients with NCP were input cases; in the later stages, the main route of infection was close contact within the family. Close contact history in epidemiology, nucleic acid detection, and chest imaging were important references for diagnosis. Antiviral therapy resulted in good therapeutic effects. Adopting multi-departmental consultation and remote consultation in combination with traditional Chinese medicine treatment and psychological counseling may result in a good short-term prognosis.
Favorable response of a patient with primary B/myeloid mixed phenotype acute Leukemia to CD19-CAR-T: Case report and literature review
Authors: Wang Lixin , Pang Yanbin , Fang Chuling , Zhao Weiqiang , Xu Yuanyuan , Guo Xiao , Qiao Jingqiao , Mei Junhui , Wang Hongxin , Yu Chuan , Li Yisheng , Tang Zhixiong , Yu Li
Published: December 2023

Rationale:

Mixed phenotype acute leukemia (MPAL) is a rare and heterogeneous type of leukemia known for its poor prognosis. The optimal treatment strategy for this condition currently lacks consensus, leaving uncertainty in its management. Nonetheless, a potential therapeutic option for patients with refractory MPAL who express target antigens is donor-derived chimeric antigen receptor T (CAR-T) cell therapy.

Patient concerns:

We recently reported a 61-year-old woman with MPAL and elucidated its diagnosis and treatment.

Diagnosis:

The diagnosis of MPAL was established based on the classification of World Health Organization in 2016.

Interventions:

Despite undergoing 3 different acute lymphoblastic leukemia (ALL) regimens and 1 acute myelogenous leukemia (AML) regimen, the patient did not achieve remission. Subsequently, the patient received human CD19-targeted CAR-T cell therapy.

Outcomes:

The patient achieved a successful and complete remission after CAR-T cell therapy. Tragically, 8 months after CAR-T infusion, the patient experienced a relapse characterized by CD19-negative disease and ultimately passed away.

Lessons:

This case underscores the potential efficacy and safety of human-derived CD19 CAR-T cell therapy in treating refractory MPAL. While this particular patient outcome was unfortunate, it suggests that CAR-T cell therapy may still hold promise as a viable treatment option for MPAL patients unresponsive to other therapies. Further research in this field is warranted to determine the most effective treatment strategies for managing this challenging disease.

Authors: Zhang Dong , Xiang Kai-fang , Xiang Cheng , Wu Yan , Wang Ling
Published: December 2023

Advanced and metastatic THCA patients usually have a poor prognosis. Thus, this study aimed to establish a risk model to discriminate the high risk population. The expression and clinical data were obtained from TCGA database. The cluster analysis, lasso, univariate and multivariate cox analyses were used to construct risk model. K-M, ROC and DCA were applied to validate the efficiency and stability of the model. GO, KEGG, and ssGSEA analysis were performed to identify the potential mechanism of signatures. The 7-gene prognosis model was constructed, including FAM27E3, FIGN, GSTM4, BEX5, RBPMS2, PHF13, and DCSTAMP. ROC and DCA results showed our model had a better prognosis prediction performance than other risk models. The high risk score was associated with the poor prognosis of THCA patients with different clinical characteristics. The risk score was closely related to cell cycle. Further, we found that the expressions of signatures were significantly dysregulated in THCA and associated with prognosis. These gene expressions were affected by some clinical characteristics, methylation and CNV. Some signatures played a role in drug sensitivity and pathway activation. We constructed a 7-gene signature model based on the integrin-related genes, which showed a great prognostic value in THCA.

Published: December 2023

The objective of this study is to explore the application effect of B-ultrasound positioning in assisting nasointestinal tube implantation in critically ill patients. This study is a retrospective study. In this study, 90 cases of severe patients with nasointestinal tube implantation were included. According to the different ways of nasointestinal tube insertion received by patients, 61 patients with conventional blind insertion methods were included in the blind insertion group, and 29 patients with conventional methods and B-ultrasound assisted positioning were included in the B-ultrasound positioning group. The general clinical data, success rate of catheterization, catheterization time, pyloric passage rate, and target nutritional value time of the 2 groups were compared. The changes of the 2 groups after catheterization were compared by SOFA and APACHE II. The contents of albumin and lymphocyte count were compared between the 2 groups before and after catheterization. The time of target nutritional value of the patients of the B-ultrasound positioning group was markedly decreased comparing with the patients of the blind insertion group. The index of catheterization time of the patients between the blind insertion group and B-ultrasound positioning group had no obvious contrast. The APACHE II score and SOFA score of the patients of the B-ultrasound positioning group were obviously lower than the blind insertion group. The contents of lymphocyte count of the patients of the B-ultrasound positioning group were markedly increased comparing with the patients of the blind insertion group after catheterization, but the contents of albumin content had no obvious change. The scores of respiratory system, circulatory system, nervous system, and urinary system in the B-ultrasound positioning group were significantly higher than those in the blind insertion group, while the COPT scores were significantly lower than those in the blind insertion group. B-ultrasound assisted nasointestinal tube implantation is well tolerated in critically ill patients, and can effectively ameliorate the nutritional status and of the ill patients.

Authors: Gao Zhiling , Yin Shuomiao , Jin Kui , Nie Weiqun , Wang Longmei , Cheng Ling
Published: December 2023

Background:

This meta-analysis aimed to assess the efficacy and safety of probiotics in conjunction with early enteral nutrition for the treatment of severe acute pancreatitis (SAP). This study focused on multiple clinical endpoints, including mortality rate, risk of organ failure, and duration of hospital stay.

Methods:

In accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. The study adhered to the Patient, Intervention, Comparison, Outcome framework and utilized randomized controlled trials to examine the impact of probiotics on patients with SAP. Data extraction and quality assessment were conducted independently by 2 evaluators, with discrepancies resolved collaboratively, or by a third adjudicator. Statistical analyses were performed using chi-square statistics, I
2 metrics, and both fixed- and random-effects models, as dictated by heterogeneity levels.

Results:

The meta-analysis covered 6 randomized controlled trials. Compared to control groups (placebo or standard care without probiotics), probiotics did not significantly reduce mortality rates or organ failure risk. However, they notably shortened hospital stays by a weighted mean difference of −5.49 days (95% confidence interval: −10.40 to −0.58; P = .010). The overall bias risk was low to moderate.

Conclusions:

Probiotics combined with early enteral nutrition did not significantly improve mortality rates or reduce the risk of organ failure in patients with SAP, but shortened hospital stays. Further studies are required to corroborate these findings.
Demographic characteristics and prognosis of HHV8-positive diffuse large B-cell lymphoma, not otherwise specified: Insights from a population-based study with a 10-year follow-up
Authors: Wang Fan , Du Zhen
Published: December 2023

HHV8-positive diffuse large B-cell lymphoma, not otherwise specified (HDN) is a subtype of lymphoma that usually arises in association with HHV8-positive multicentric Castleman disease. However, the epidemiology, treatment patterns, and survival outcomes of HDN are poorly understood. A retrospective analysis was performed for 67 patients with HDN diagnosed from 2011 to 2020 using the SEER database. The demographic characteristics, treatment modalities, and survival outcomes of HDN patients were evaluated. Kaplan–Meier analysis and Cox regression analysis were employed to identify prognostic factors for overall survival (OS) and disease-specific survival (DSS). The age-adjusted incidence rate of HDN was 0.010 per 100,000 person-years. The median age at diagnosis was 51.8 years with male predominance. The primary site distribution was mainly nodal (79.1%), while the extranodal sites were rarely involved (20.9%). The majority of patients were white (65.7%). Only 3.0% of patients received radiotherapy, while 55.2% received chemotherapy. The 1-year, 3-year, and 5-year OS was 67.4%, 65.6%, 58.4%, and 56.3%, respectively, and the corresponding DSS was 73.1%, 73.1%, and 67.8%, respectively. The diagnosis year group of 2016–2020 had a significantly worse OS than the diagnosis year group of 2011–2015 (P = .040), but not for DSS (P = .074). No significant survival improvement was observed in patients underwent chemotherapy. Age and marital status were independent prognostic factors for OS, and age was an independent prognostic factor for DSS. In conclusion, HDN is a rare and aggressive disease, our study provides a comprehensive overview of the epidemiology, treatment patterns and survival outcomes of HDN patients for the first time. We revealed that older age and marital status of single were associated with worse survival of HDN, while chemotherapy was not associated with improved survival outcomes in HDN patients.

Published: December 2023

To investigate body mass index (BMI) of infertile couples and analyze its related influencing factors in Southwest China, so as to prevent and control the obesity. We analyzed the data of a total number of 8877 infertile couples who received treatment in our assisted reproductive center from October 2012 to March 2022. The mean age and BMI of men and women were 33.5 years, 23.9 kg/m2 and 31.6 years, 21.9 kg/m2. The prevalence of overweight (BMI 25–29.9) was 30.9% in men and 14.7% in women, 3.7% of men and 1.6% of women were obese (BMI ≥ 30), while 3.6% of men and 10.8% of women were underweight (BMI<18.5). Multivariable linear regression analysis indicated that the age and educational background of both women and men had an impact on BMI. In our study, the proportion of male obesity and overweight is much higher than that of female. On the other hand, the proportion of females with low weight was higher than that of males. The age and educational background of men and women have a certain correlation with BMI.

This study used metagenomic next-generation sequencing (mNGS) technology to explore the changes of the microbial characteristics in the lower respiratory tract in patients with acute exacerbations of bronchiectasis (noncystic fibrosis) to guide clinical treatment and improve patients’ quality of life and prognosis. This prospective study included 54 patients with acute exacerbation and 46 clinically stable patients admitted to the Respiratory and Critical Care Medicine Center of the People’s Hospital of Xinjiang Uygur Autonomous Region from January 2020 to July 2022. Sputum was subjected to routine microbiological tests, and bronchoalveolar lavage fluid (BALF) samples were subjected to microbiological tests and mNGS of BALF before empirical antibiotic therapy. Serum inflammatory markers (white blood cell count, interleukin-6, procalcitonin, and C-reactive protein) were measured. In addition, we evaluated the pathogen of mNGS and compared the airway microbiome composition of patients with acute exacerbation and control patients. The mean age of our cohort was 56 ± 15.2 years. Eighty-nine patients had positive results by mNGS. There was a significant difference in the detection of viruses between the groups (χ2 = 6.954, P < .01). The fungal species Candida albicans, Pneumocystis jirovecii, and Aspergillus fumigatus were significantly more common in patients with acute exacerbations (χ2 = 5.98, P = .014). The bacterial species Acinetobacter baumannii, Mycobacterium tuberculosis, Haemophilus influenzae, Haemophilus parahaemolyticus, Abiotrophia defectiva, and Micromonas micros were significantly more prevalent in patients with acute exacerbations (χ2 = 4.065, P = .044). The most common bacterial species isolated from the sputum and BALF samples of patients with acute exacerbation was A. baumannii. Chlamydia psittaci was found in 4 patients. In addition, of 77 patients with negative sputum culture, 66 had positive results by mNGS, demonstrating the increased sensitivity and accuracy of mNGS. Patients with acute exacerbation of bronchiectasis tend to have mixed infections in the lower respiratory tract. The frequency of viruses, fungi, and Mycoplasma was higher in these patients. Our findings suggest that mNGS could be used to identify pathogenic microorganisms in these patients, increasing the effectiveness of antibiotic therapy.

Renal involvement represents the major long-term morbidity associated with IgA vasculitis (IgAV). Our aim was to evaluate clinical characteristics and long-term renal outcomes of IgAV in pediatrics and adults comparing to IgA nephropathy (IgAN). Our retrospective study included children and adults with IgAV and IgAN patients, admitted in a 13-year period (2007–2019) to rheumatology clinics and in hospital pediatric and internal medicine departments. We compared frequencies of clinical manifestations, laboratory findings, treatments, long-term outcomes at 1 year follow-up, including all-cause mortality and dialysis until the end of follow-up time. A total of 60 adult IgAV, 60 pediatric IgAV and 45 IgAN patients were evaluated. Adult IgAV patients were significantly older than IgAN patients (53.1 ± 17.4 years vs 45.1 ± 15.7 years respectively, P = .02) and had significantly higher rates of cardiovascular comorbidities. The risk and time to dialysis were similar among IgAN and adult IgAV groups. Yet, overall mortality at long term follow up was higher in IgAV adult group compared to IgAN. No dialysis or renal transplantation were reported in pediatric IgAV patients. IgAV and IgAN adult patients were comparable regarding risk of end stage renal disease. Of note, high mortality rates were observed among adult IgAV group.
A meta-analysis of adverse effects of retinopathy of prematurity on neurodevelopment in preterm infants
Authors: Fang Lan , Wang Chan , Yang Yanzhang , Feng Jiajia , Chen Fengqin
Published: December 2023

Background:

Retinopathy of prematurity (ROP) increases with the survival of late preterm infants, but its relationship with neurodevelopmental outcomes in preterm infants remains controversial. To investigate the relationship between ROP and its severity and adverse neurodevelopmental outcomes in preterm infants.

Methods:

We conducted a meta-analysis. All relevant literature before November 2022 were retrieved from PubMed, Embase, Cochrane Library Web of Science, CNKI, CBM, Wan fang Data, and VIP Database. According to the inclusion criteria and exclusion criteria, eligible literature were included to conduct clinical trial quality assessment, and the Newcastle-Ottawa scale was used to evaluate the quality of evidence. Meta-analysis was performed using RevMan5.3. Data extraction, quality assessment, and meta-analysis were performed independently by 2 people. Mean difference or standardized mean difference of motor, language and cognitive scores (Bayley III or Bayley II) were used as effect sizes for continuous data analysis, all of which were represented by 95% CI. For heterogeneity (I
2 ≥ 50% or P < .10), a random effects model was used, otherwise a fixed effects model was used.

Results:

A total of 6 literature were included. The results of the ROP group for motor (comprehensive motor, proportional motor, and fine motor), language and cognitive scores were −5.57 (95%CI, −1.43 to 0.04), −0.95 (95%CI, 1.4–0.50), −1.34 (95% CI, 1.77–0.92), −1.75 (95% CI, 2.26–1.24) and −5.56 (95% CI, 9.56–1.57). Additionally, the results of severe ROP group for motor (comprehensive motor, proportional motor, fine motor), language and cognitive scores were −8.32 (95%CI, −8.91 to 7.74), −1.10 (95%CI, −1.83 to −0.36), −1.08 (95%CI, −1.75 to −0.41), −7.03 (95%CI, −7.71 to 6.35), and −7.96 (95%CI, −8.5 to −7.42).

Conclusions:

The Bayley Scale scores of the ROP group were lower than those of the not ROP group, and the scores of the severe ROP were significantly lower than those of the not severe ROP group. These findings suggest that ROP can indeed delay motor, language and cognitive, especially in severe cases.
Bronchiole adenoma/pulmonary ciliated mucinous nodular papillary tumor: Case series and literature review
Authors: Liu Shanshan , Cai Xiaoshan , Pan Jianliang , Liu Shaoyun , Lin Jianjun , Yue Xianwen
Published: December 2023

Objective:

To analyze the clinical-pathological characteristics of 3 cases of bronchiolar adenoma/pulmonary ciliary mucinous nodular papillary tumors, and to improve the understanding of bronchiolar adenoma (BA)/ciliated muconodular papillary tumors (CMPT) (bronchiolar adenoma/ciliated muconodular papillary tumor).

Methods:

Retrospective analysis was done on the clinical information, diagnosis, and treatment of 3 instances of BA/CMPT at the Second People’s Hospital of Weifang City. By scanning the CNKI, Wanfang, VIP database, and Pubmed database using the English key words “bronchiolar adenoma, ciliated muconodular papillary tumor,” respectively patients with comprehensive clinical data were gathered, and studies from January 2002 to August 2021 that were relevant to the patients were examined.

Results:

A total of 35 articles and 71 instances were found, including 3 cases in our hospital, for a total of 74 cases. There were 31 males and 43 females among them, ranging in age from 18 to 84 years (average 63 years), and 15 cases had a smoking history. The majority of them were discovered by physical examination and had no clinical symptoms. The majority of the imaging revealed solid nodules with variable forms, with some ground-glass nodules displaying vacuole and bronchial inflation signs. BA/CMPT are generally gray-white, gray-brown solid nodules with obvious boundaries but no envelope with a maximum dimension of 4 to 45 mm (average 10.6 mm) on gross examination. Acinar, papillary, and lepidic formations can be seen under the microscope at high magnification; the majority of these structures are made up of tripartite epithelial components, including basal cells, mucous cells, ciliated columnar cells, and alveolar epithelial cells, demonstrating a variety of combinations. An important basis for diagnosis in immunohistochemistry is the continuous positive basal cell layer that is shown by p63, p40, and CK5/6. BRAF and epidermal growth factor receptor are the genes that are most frequently mutated. All of the patients showed no signs of metastasis or recurrence during follow-up period.

Conclusion:

BA/CMPT is a rare benign tumor of lung epithelium. Because imaging and intraoperative cryosection diagnosis are easy to be misdiagnosed as malignant, it is necessary to further improve understanding and improve immunohistochemistry and genetic examination.

Published: December 2023

Background:

Chronic heart failure (CHF) is the terminal stage of several diseases. The present study aimed to investigate the impact of palliative care on the physical and mental status and quality of life of patients with CHF.

Methods:

This single-center randomized controlled clinical trial was conducted at Xiangtan Central Hospital. A total of 103 cases were included and divided into a study group (n = 54) and a control group (n = 49). The control group received usual care, whereas the study group received usual care plus palliative care. Statistical analyses were conducted on Simplified Coping Style Questionnaire, negative emotions, Minnesota Living with Heart Failure Questionnaire scores, and nursing satisfaction before and after intervention in the 2 groups.

Results:

After the intervention, the positive coping style score in the research group was higher than that in the control group, while the negative coping style score was lower than that of the control group (P < .05). After the intervention, the Beck Anxiety Inventory and Beck Depression Inventory-II scores of the 2 groups decreased compared to before the intervention, and the study group had lower scores than the control group (P < .05). After the intervention, the Minnesota Living with Heart Failure Questionnaire scores of the 2 groups decreased compared to those before the intervention, and the study group had lower scores than the control group (P < .05). Nursing satisfaction of the research group (94.44%) was higher than that of the control group (81.63%) (P < .05).

Conclusions:

Adopting palliative care to intervene in CHF patients can effectively regulate their physical and mental state, alleviate negative emotions, transform coping styles towards the disease, and improve their quality of life, with high patient satisfaction.
The prognostic value of Forkhead box P3 regulatory T cells in biliary tract cancer: A systematic review and meta-analysis
Authors: Cai Pengcheng , Wu Zhongli , Yang Xingjian , Wang Na , Yang Yong
Published: December 2023

Background:

This study aimed to explore the value of tumor-infiltrating Forkhead box P3(FoxP3+) regulatory T cells (Tregs) in evaluating the prognosis of biliary tract cancer.

Methods:

Four electronic databases were searched using 2 computers: PubMed, Embase, Web of Science, and Cochrane Library. The vocabulary and syntax were adapted according to the database. Two researchers independently selected the studies, collected information, and assessed the risk of bias. The Meta-analysis was performed using STATA 17.0, and HR and its corresponding 95% CI were used to evaluate the correlation between FoxP3+ Tregs and the overall survival of patients with biliary tract cancer. In addition, the quality of the included studies was evaluated.

Results:

Ten articles were included in this study. The results of the meta-analysis showed that patients with high FoxP3+ Tregs infiltration had worse overall survival (OS) (HR = 1.34,95% CI 1.16 to 1.71; P < .001). Subgroup analysis of gallbladder carcinoma and cholangiocarcinoma showed that the high infiltration of FoxP3+ Tregs was significantly correlated with the OS of the former (HR = 1.55,95% CI 1.11 to 2.00; P < .001), but not with the OS of the latter (HR = 1.00,95% CI 0.62 to 1.38; P > .05).

Conclusions:

Our meta-analysis reveals that high infiltration of FoxP3 + Tregs is significantly associated with reduced overall survival in gallbladder carcinoma, endorsing their use as a prognostic biomarker for this subtype. In contrast, no significant prognostic correlation was identified for FoxP3+ Tregs in cholangiocarcinoma, indicating the need for subtype-specific evaluation of their prognostic relevance in biliary tract cancers.

Published: December 2023

The objective of this study is to explore the relationship between cuproptosis-related long noncoding RNAs (lncRNAs) in hepatocellular carcinoma (HCC). RNA-seq data, including lncRNAs and related clinical information of HCC patients, were downloaded from The Cancer Genome Atlas database. A signature composed 3 cuproptosis-related lncRNAs was constructed by LASSO analysis, and HCC patients were classified into high- and low-risk groups. Patients in the high-risk group had a poorer prognosis compared with the low-risk group. Univariate Cox and multivariate Cox regression analyses confirmed that the signature model was an independent risk factor compared to other clinical biomarkers. Furthermore, gene set enrichment analysis indicated that metabolism-related pathways were enriched in low-risk group, including drug metabolism, and fatty acid metabolism. Further research demonstrated that there were markedly differences in drug response between the high- and low-risk group. Immune related analysis showed that the most type of immune cells and immunological function in the high-risk group were different with the risk-group. Finally, TP53 mutation rate and the tumor mutational burden in the high-risk group were higher compared with the low-risk group. In conclusion, we constructed a prognostic signature based on the expression of cuproptosis-related lncRNAs to predict HCC patients’ prognosis, drug response and immune microenvironment, and further research will be conducted to uncover the mechanisms.

Authors: Liu Xiaoqiang , Huan Yisen , Wang Yubin , Huang Yingxuan
Published: December 2023

Introduction:

We describe a rare case of a 54-year-old male diagnosed with both ulcerative colitis (UC) and hepatitis C virus (HCV), posing clinical challenges.

Patient Concerns:

The patient showed worsened UC symptoms, leading to further evaluations.

Diagnosis:

Dual diagnosis of UC and HCV was confirmed through endoscopy and serological tests, ruling out other hepatic causes. Interventions: Treatment involved methylprednisolone for UC and sofosbuvir/velpatasvir for HCV, with attention to drug interactions.

Outcomes:

Significant improvement was observed in both UC symptoms and HCV viral load post-treatment.

Conclusion:

This case underscores the need for nuanced treatment in managing concurrent UC and HCV, considering potential drug interactions and disease impacts.
Contrast-medium injury of spinal cord after cerebral angiography using nonionic contrast agents: A case report and literature review
Authors: Zhuo Shitu , Cao Lijing , Yang Meili , Chen Jixing , Yu Zheng
Published: December 2023

Introduction:

Contrast-induced spinal cord injury (CIS) is an uncommon yet severe neurological complication following cerebral angiography. It can lead to dire consequences, including limb paralysis, respiratory distress, and even death.

Patient concerns:

After undergoing cerebral angiography, a 41-year-old male initially displayed symptoms of dizziness and blurred vision, which advanced into dysphoria and limb weakness within 3 hours. These initial symptoms diminished by the 12th hour. Yet, 18 hours following the procedure, the patient developed quadriplegia and paresthesia below the T5 level, even though his deep sensory functions persisted unaffected.

Diagnosis:

The magnetic resonance imaging and diffusion weighted imaging scans excluded the presence of cerebrovascular ischemia or subarachnoid hemorrhage. However, the magnetic resonance angiography displayed arterial vasospasms in both posterior cerebral arteries and the V4 segment of the right vertebral artery. The encephalopathy symptoms faded within 12 hours, suggesting a probable contrast-induced encephalopathy diagnosis. An magnetic resonance imaging on day 4 revealed an intensified signal in the spinal cord from C1 to T1. This finding supported the diagnosis of CIS.

Interventions:

Following treatment with mannitol, methylprednisolone, and nimodipine, the patient’s contrast-induced encephalopathy symptoms resolved completely within 12 hours. With a 2-week regimen of aspirin, methylprednisolone, and rehabilitative training, the neurological symptoms from CIS showed steady improvement.

Outcomes:

The symptoms and signs of CIS gradually improved after 2 weeks’ treatment and rehabilitation program.

Conclusion:

Given the grave outcomes of CIS, like limb paralysis, breathing difficulties, and even fatality, it is imperative to remain cautious about this complication, even with the use of modern, less harmful contrast agents.
Genetic perspectives on the influence of circulating cytokines on acne: A Mendelian randomization study
Authors: Li Jiaxuan , Lu Yining , Zhao Xuelian
Published: December 2023

Previous studies have reported that the occurrence and development of acne are closely associated with immune-inflammatory responses. Mendelian randomization was performed to further assess the causal correlation between 41 inflammatory cytokines and acne. Mendelian two-sample randomization utilized genetic variants for acne from a large open genome-wide association study (1299 cases and 211,139 controls of European ancestry) and inflammatory cytokines from a genome-wide association study abstract containing 8293 healthy participants. The causal relationship between exposure and outcome was explored primarily using an inverse variance weighting approach. In addition, multiple sensitivity analyses including MR-Egger, weighted median, simple model, weighted model, and MR-PRESSO were applied simultaneously to enhance the final results. The results suggest that il-10, MIP-1A, and SCGF-β are suggestive of the risk of acne in clinical practice (OR = 0.799, 95% CI = 0.641–0.995, P = .045; OR = 0.55, 95% CI = 0.388–0.787, P = .001; OR = 1. 152, 95% CI = 1.001–1.325, P = .048). Our study conclusively identified a causal relationship between il-10 and circulating levels of acne risk and a suggestive link between MIP-1A and SCGF-β and acne. Our study may provide greater insight into the pathogenesis of acne and develop effective management strategies for the clinic. We believe that IL-10, MIP-1A, and SCGF-β could be potential therapeutic targets for acne development.

There is a need to consider the geographical origins when studying the association between COVID-19 and the comorbid conditions. To examine the role of inflammation in determining the severity of COVID-19 among hospitalized patients with diabetes and compare these roles with those who does not have diabetes. A cross sectional comparative design was used with a convenience sample of 352 patients. Samples were collected from hospitalized patients with COVID-19 who were divided into 2 groups (diabetes and non-diabetes). Data regarding results of selected inflammatory markers and sociodemographic were collected. The severity of COVID-19 differed significantly between the diabetes and non-diabetes groups (Chi square = 25.58 P < .05). There was significant difference in the mean scores of neutrophil counts, monocyte count, Basophil count, erythrocyte sedimentation rate, partial thromboplastin time, C-creative protein, platelets, white blood cells, and mean cellular hemoglobin center between those with and those without diabetes. The diabetes were shown more increased in the predictors and severity of the COVID-19 disease. However, neutrophil to lymphocyte ratio, neutrophil count, and age were the significant predictors of the severity level of COVID-19 among patients with diabetes. In conclusion, our study addressed the influence of having diabetes among hospitalized patients with moderate and severe COVID-19 infection. The results showed that severity of COVID-19 infection was affected by diabetes where those with diabetes had more tendency to suffer from the severe form of the disease rather that the moderate level.
Endoscopic papillectomy combined with endoscopic retrograde cholangio-pancreatography for duodenal gangliocytic paraganglioma: A case report
Authors: Cai Wenpin , Hu Weitao , Fang Taiyong
Published: December 2023

Rationale:

Gangliocytic paraganglioma is a rare tumor that can occur in several organs throughout the body. Gangliocytic paraganglioma of the main duodenal papilla is even rarer. This study analyzes and discusses the endoscopic management of a case of gangliocytic paraganglioma of the main duodenal papilla and reviews the relevant literature. It is hoped that this study will increase clinicians’ awareness of this disease.

Patient concerns:

Electron endoscopy reveals a duodenal main papillary tumor, and the patient desires further clarification of the nature of the tumor and the next step in the treatment plan.

Diagnoses:

Duodenal gangliocytic paraganglioma.

Interventions:

As the patient lesion was located in the main duodenal papilla, we successfully performed endoscopic minimally invasive treatment of the tumor by endoscopic papillectomy combined with endoscopic retrograde cholangiopancreatography.

Outcomes:

The patient was discharged after the postoperative removal of the nasobiliary drain and returned to the hospital 2 months later to have the biliary stent removed; the patient was in good general condition at follow-up.

Lessons:

For duodenal main papillary tumor, we need to be alert to the possibility of gangliocytic paraganglioma. Since the tumor is located in the submucosa of the juxta-abdominal region, the preoperative biopsy positivity rate is low, and the tumor is often adjacent to or involves the biliopancreatic duct, endoscopic resection combined with endoscopic retrograde cholangiopancreatography can be considered for diagnosis and treatment.
Gitelman syndrome combined with diabetes mellitus: A case report and literature review
Authors: Huang Xiaoyan , Wu Miaohui , Mou Lunpan , Zhang Yaping , Jiang Jianjia
Published: December 2023

Rationale:

Gitelman syndrome (GS) is an uncommon autosomal recessive tubulopathy resulting from a functional deletion mutation in the SLC12A3 gene. Its onset is typically insidious and challenging to discern, and it is characterized by hypokalemia, metabolic alkalosis, and reduced urinary calcium excretion. There is limited literature on the diagnosis and management of GS in individuals with concomitant diabetes.

Patient concerns:

A 36-year-old male patient with a longstanding history of diabetes exhibited suboptimal glycemic control. Additionally, he presented with concurrent findings of hypokalemia, hypomagnesemia, hypocalciuria, and metabolic alkalosis.

Diagnosis:

Building upon the patient’s clinical manifestations and extensive laboratory evaluations, we conducted thorough genetic testing, leading to the identification of a compound heterozygous mutation within the SLC12A3 gene. This definitive finding confirmed the diagnosis of GS.

Interventions:

We have formulated a detailed medication regimen for patients, encompassing personalized selection of hypoglycemic medications and targeted electrolyte supplementation.

Outcomes:

Following 1 week of comprehensive therapeutic intervention, the patient’s serum potassium level effectively normalized to 3.79 mmol/L, blood glucose parameters stabilized, and there was significant alleviation of clinical symptoms.

Lessons:

GS has a hidden onset and requires early diagnosis and intervention based on patient related symptoms and laboratory indicators in clinical practice, and personalized medication plans need to be provided according to the specific situation of the patient.

Patients with type 2 diabetes who have HbA1c values ≥ 10% have different previous glycemic trends, including new diagnosis of diabetes. We aimed to assess the efficacy of 3 months of intensive and facilitated antihyperglycemic treatment in patients with different glycemic backgrounds. In this observational study, patients with type 2 diabetes and poor glycemic control (indicated by an HbA1c level of > = 10%) were divided into groups based on their previous HbA1c levels (group 1; newly diagnosed type 2 diabetics, group 2; patients with previously controlled but now deteriorated HbA1c levels, group 3; patients whose HbA1c was not previously in the target range but was now above 10%, and group 4; patients whose HbA1c was above 10% from the start). Patients received intensive diabetes management with close monitoring and facilitated hospital visits. For further analysis, patients who were known to have previously had good metabolic control (either did not have diabetes or had previously had an HbA1c value < =7) and patients who had prior poor metabolic control were analyzed separately. Of the 195 participants [female, n = 84 (43.1%)], the median age was 54 years (inter-quantile range [IQR] = 15, min = 29, max = 80) and the median baseline HbA1c was 11.8% (IQR = 2.6%, min = 10%, max = 18.3%). The median duration of diabetes was 10 years (IQR = 9, min = 1, max = 35) when newly diagnosed patients were excluded. The ≥ 20% reduction in HbA1c at month 3 was observed in groups 1 to 4 in 97%, 88.1%, 69.1%, and 55.4%, respectively. The percentage of patients who achieved an HbA1c level of 7% or less was 60.6%, 38.1%, 16.4%, and 6.2% in the groups, respectively. The rate of those who achieved an HbA1c of 7% or less was nearly 50% of patients with type 2 diabetes mellitus who had previously had good metabolic control, whereas successful control was achieved in only 1 in 10 patients with persistently high HbA1c levels. Patients’ glycemic history played an important role in determining their HbA1c levels at 3 months, suggesting that previous glycemic management patterns may indicate future success in diabetes control.
