Characteristics and outcomes of in-hospital cardiac arrest in adults hospitalized with acute coronary syndrome in China

AimsThis retrospective study aims to analyze and explore the clinical characteristics, risk factors, and in-hospital outcomes - including return of spontaneous circulation (ROSC) and survival to discharge - of hospitalized patients admitted with acute coronary syndrome (ACS) suffering cardiac arrest.MethodsACS patients admitted to three tertiary hospitals in Fujian, China, were evaluated retrospectively from January 1, 2012 to December 30, 2016. Data were collected, based on the Utstein Style, for all cases of attempted resuscitation for IHCA. We analyzed patient characteristics, pre-event variables, event variables, and the main outcomes, including ROSC and survival to discharge, and identified the influencing factors on the outcomes.ResultsThe total number of ACS admissions across the three hospitals during this study period was 21,337. Among these admissions, 320 ACS patients experienced IHCA (incidence: 1.50%); 134 (41.9%) patients experienced ROSC; and 68 (21.2%) survived to discharge. The findings indicated that four factors were associated with ROSC, including age <70 years-old, shockable rhythm, duration of resuscitation (≤15 min and 16–30 min), and PCI. Five factors were associated with survival to discharge, including age <70 years-old, shockable rhythm, the duration of resuscitation (≤15 min and 16–30 min), Killip ≤ II, and CCI ≤ 2.ConclusionYounger age, shockable rhythm, and shorter duration of resuscitation were all factors demonstrated to be a predictor of ROSC and survival to hospital discharge.     

Decreased expression levels of DAL-1 and TOB1 are associated with clinicopathological features and poor prognosis in gastric cancer

PurposeWe previously demonstrated that the functional inactivation of DAL-1 and TOB1 promotes an aggressive phenotype in gastric cancer cells, but the links between both genes and the survival of patients with gastric cancer are unknown. Here, we investigated the correlations of the expression levels of DAL-1 and TOB1 with the progression of gastric cancer.MethodsA total of 270 patients who underwent resectable gastrectomy were included. The expression of DAL-1 and TOB1 was detected by immunohistochemistry.ResultsLow expression of DAL-1 in cancer tissue was significantly associated with tumor site (p < 0.05), histological grade (p < 0.01), depth of invasion (p < 0.05), lymph node metastasis status (p < 0.05), Lauren classification (p < 0.001), and clinical stage (p < 0.01). A lower level of TOB1 was observed in gastric cancer patients with diffuse type disease compared to patients with either intestinal or mixed type disease (p < 0.001). Additionally, Spearman’s correlation analysis revealed that decreased expression of DAL-1 was positively correlated with low TOB1 expression (r=0.304, p < 0.001). The survival analysis showed that low levels of DAL-1 and TOB1 were significantly associated with poor survival of gastric cancer patients (p <0.001 and p < 0.05, respectively).ConclusionThe downregulation of DAL-1 and TOB1 expression is associated with shorter survival of gastric cancer patients. Hence, DAL-1 and TOB1 may be considered potential novel markers for predicting the outcomes of patients with gastric cancer.     

Cross-Cultural Adaptation,Reliability, and Validity of the Chinese Version of the Tampa Scale for Kinesiophobia-11 Among Patients Who Have Undergone Total Knee Arthroplasty

BackgroundThe shortened version of the Tampa Scale for Kinesiophobia (TSK-11) has been well characterized in the literature. However, to the best of our knowledge, no previous studies have evaluated the reliability and validity of the TSK-11 for Chinese-speaking patients who have undergone total knee arthroplasty (TKA). Thus, the objectives of this study were to translate and adapt the TSK-11 cross-culturally into Chinese and to evaluate its reliability and validity in a sample of Chinese TKA patients.MethodsThe TSK-11 was translated and cross-culturally adapted into Chinese according to the international guidelines for the cross-cultural adaptation of self-report measures. The Chinese version of TSK-11 was administered to 254 patients following their TKA, along with the Fear-Avoidance Beliefs Questionnaire, Pain Catastrophizing Scale, Numerical Rating Scale, and 12-Item Short Form Health Survey. Psychometric testing included internal consistency, test-retest reliability, floor and ceiling effects, construct validity, and convergent validity.ResultsA high completion rate of 95.8% with no floor or ceiling effects was noted in the Chinese version of the TSK-11. The questionnaire also showed good internal consistency (Cronbach’s α = 0.883) and test-retest reliability (intraclass correlation coefficient = 0.798). Construct validity was assessed by exploratory factor analysis, and 3 factors were extracted that accounted for 65.2% of the variance. Convergent validity was confirmed by significant Pearson correlations between the Chinese version of the TSK-11 and the Pain Catastrophizing Scale (r = 0.751), Fear-Avoidance Beliefs Questionnaire (r = 0.719) and VAS (r = 0.450), as well as the 12-Item Short Form Health Survey subdomains Bodily Pain (r = ?0.391), Mental Health (r = ?0.356), Physical Functioning (r = ?0.339), Role-Emotional (r = ?0.317), and Role-Physical (r = ?0.277).ConclusionThe Chinese version of the TSK-11 demonstrated satisfactory acceptability, reliability, and validity; therefore, it can be used in clinical practice and research for assessing kinesiophobia in Chinese patients after TKA.     

Chevron osteotomy versus scarf osteotomy for hallux valgus correction: A meta-analysis

BackgroundThis study intended to investigate the optimal surgical strategy in hallux valgus (HV), and to provide a basis for clinical treatment of HV.MethodsStudies related to chevron osteotomy and scarf osteotomy for HV were enrolled from online databases. Hallux valgus angle (HVA) was the main outcome variable. Enrolled studies included posttreatment data for intermetatarsal angle (IMA), American Orthopaedic Foot & Ankle Society (AOFAS) score, and complications. A random-effects model was applied for significant heterogeneity. Otherwise, a fixed-effects model was used. Heterogeneity was assessed with Q test and I² statistics. Publication bias was evaluated with Egger's test. Based on the influence of weighted mean difference values or odds ratios, a sensitivity analysis was performed.ResultsFour studies including 384 subjects were evaluated to determine the optimal surgical strategy for HV. There was no statistically significant difference between chevron and scarf groups for HVA, IMA, AOFAS score, and complication rates. Sensitivity analysis showed good stability. The likelihood of publication bias was small.ConclusionThe effects of chevron osteotomy and scarf osteotomy for HV are comparable. Chevron osteotomy is less technically demanding.     

Risk Factors for Pressure Sores in Hospitalized Acute Ischemic Stroke Patients

BackgroundAcute ischemic stroke patients are a group at high risk for pressure sores. It is important to identify risk factors for pressure sores in acute ischemic stroke patients in order to facilitate early adoption of appropriate preventive and treatment measures.MethodsData were derived from the China National Stroke Registry. Acute ischemic stroke patients aged >18 years who presented at the hospital within 14 days after the onset of symptoms were eligible for this study. Comprehensive baseline data were collected. The definition of pressure sores was based on assessment at discharge of whether the patient had pressure sores at any time during hospitalization.Results12,415 patients with a mean age of 67 years and a mean length of hospitalization of 14 days were included in the study. Among these patients, 97 (0.8%) had pressure sores during hospitalization. In the multivariate analysis of risk factors for pressure sores, age (each increment of 5 years), being unmarried, NIHSS at admission (each increment of 3 points), mRS at admission (3-5 points), diabetes mellitus, hemoglobin at admission (each incremental reduction of 10 units), and history of peripheral vascular disease all were significantly correlated with the occurrence of pressure sores among acute ischemic stroke patients during hospitalization.ConclusionsOld age, severe neurological disability, being unmarried, low hemoglobin, and history of diabetes mellitus and peripheral vascular disease were risk factors for pressure sores in acute ischemic stroke patients.     

Activation of leukocyte immunoglobulin-like receptor B2 signaling pathway in cortical lesions of pediatric patients with focal cortical dysplasia type IIb and tuberous sclerosis complex

BackgroundsFocal cortical dysplasia type IIb (FCD IIb) and tuberous sclerosis complex (TSC) are very frequently associated with epilepsy in pediatric patients. Human leukocyte immunoglobulin-like receptor B2 (LILRB2) participates in the process of neurite growth, synaptic plasticity, and inflammatory reaction, suggesting a potential role of LILRB2 in epilepsy. However, little is known about the distribution and expression of LILRB2 in cortical lesions of FCD IIb and cortical tubers of TSC.MethodsIn this study, we have described the distribution and expression of LILRB2 signaling pathway in cortical lesions of pediatric patients with FCD IIb (n = 15) and TSC (n = 12) relative to age-matched autopsy control samples (CTX, n = 10), respectively. The protein levels of LILRB2 pathway molecules were assessed by western blotting and immunohistochemistry. The expression pattern was investigated by immunohistochemistry and double labeling experiment. Spearman correlation analysis to explore the correlation between LILRB2 protein level and seizure frequency.ResultsThe protein levels of LILRB2 and its downstream molecules POSH, SHROOM3, ROCK1, ROCK2 were increased in cortices of patients compared to CTX. Protein levels of LILRB2 negatively correlated with the frequency of seizures in FCD IIb and TSC patients, respectively. Moreover, all LILRB2 pathway molecules were strongly expressed in dysmorphic neurons, balloon cells, and giant cells, LILRB2 co-localized with neuron marker and astrocyte marker.ConclusionTaken together, the special expression patterns of LILRB2 signaling pathway in cortical lesions of FCD IIb and TSC implies that it may be involved in the process of epilepsy.     

Therapeutic effects of topical 0.03% Tacrolimus ointment in children with refractory vernal keratoconjunctivitis in Middle East

ObjectiveThe purpose of this paper is to review the efficacy and safety profile in children treated with topical 0.03% Tacrolimus ointment for vernal keratoconjunctivitis in Middle East and to propose a treatment posology. According to recent studies, a complex non-IgE dependent mechanism plays a relevant role in the pathogenesis of vernal keratoconjunctivitis. Numerous cells and mediators have been found in the serum, conjunctiva and tears of patients with Vernal keratoconjunctivitis.DesignThis case series included 10 patients from a single centre, pediatric department of a tertiary hospital with active symptomatic vernal keratoconjunctivitis. All the patients had proliferative lesions and corneal involvement despite conventional medications, including topical steroids. All other medications, systemic and topical: steroids, antihistamines and cyclosporine, were unsuccessful. Patients were treated with topical 0.03% Tacrolimus ointment twice daily for 8 weeks and then once a day for the next two month followed by thrice a week for two months. The changes in symptoms and signs after treatment were evaluated, also the development of possible complications was assessed.ResultsThe results showed a significant reduction in signs and symptoms after 4 weeks of the treatment. Clinical resolution of giant papillae and corneal lesions were seen within eight weeks and no additional drug was required during that period, except tear substitutes. Treatment was continued for period of two months and then slowly reduced.ConclusionThe use of 0.03% Tacrolimus ointment is safe and effective in children refractory to conventional treatment of vernal keratoconjunctivitis even in high temperature climate as Middle East. Due to the effectiveness of the treatment, the dosage used may be proposed for conventional use.     

Successful Treatment for BK Virus Nephropathy by Leflunomide in a Kidney Transplant Patient: A Case Report

IntroductionThe immunosuppressant agents in kidney transplantation (KT) may lead to various complications such as opportunistic infections and malignancies. BK virus associated nephropathy is a significant complication following KT, and it can result in graft failure. BK virus causes tubulointerstitial nephritis, ureter stenosis, and even graft failure in KT recipients with impaired immune system. We described a 63-year-old woman, who was a hepatitis C carrier and on dialysis for 22 years before KT, who received cadaveric-donor KT 2 years previously. She reported decreasing urine output and general weakness. The serum creatinine level was slightly increased from 2.94 to 4.38 mg/dL.MethodsImmunosuppressant medications including prednisolone, everolimus, cyclosporin, and mycophenolate sodium were continued as maintenance therapy post KT. Kidney biopsy was performed due to deterioration of graft function.ResultsThe kidney biopsy showed consistent results with early-stage polyomavirus nephropathy, characterized by focal viral cytopathic changes with positive immunohistochemical signals and mesangial proliferative glomerulonephritis, immune-complex-mediated (Fig 1 and Fig 2). Negative C4d staining at peritubular capillary was reported. The dosage of mycophenolate sodium was tapered from 720 to 360 mg daily and that of everolimus increased from 0.5 to 1.0 mg daily due to BK viral infection with BK nephropathy. The serum creatinine level was 2.75 mg/dL after treatment.ConclusionEarly detection of BK nephropathy and decreasing immunosuppressant agents are the mainstay of treatment. Substituting leflunomide for mycophenolate sodium and increasing dosage of everolimus has been proposed to solve BK nephropathy. We presented that the use of leflunomide in such situation is in a timely manner.
