Local vibration training improves the recovery of quadriceps strength in early rehabilitation after anterior cruciate ligament reconstruction: A feasibility randomised controlled trial

BackgroundAfter anterior cruciate ligament reconstruction (ACLR), quadriceps strength must be maximised as early as possible.ObjectivesWe tested whether local vibration training (LVT) during the early post-ACLR period (i.e., ～10 weeks) could improve strength recovery.MethodsThis was a multicentric, open, parallel-group, randomised controlled trial. Thirty individuals attending ACLR were randomised by use of a dedicated Web application to 2 groups: vibration (standardised rehabilitation plus LVT, n = 16) or control (standardised rehabilitation alone, n = 14). Experimenters, physiotherapists and participants were not blinded. Both groups received 24 sessions of standardised rehabilitation over ～10 weeks. In addition, the vibration group received 1 hour of vibration applied to the relaxed quadriceps of the injured leg at the end of each rehabilitation session. The primary outcome — maximal isometric strength of both injured and non-injured legs (i.e., allowing for limb asymmetry measurement) — was evaluated before ACLR (PRE) and after the 10-week rehabilitation (POST).ResultsSeven participants were lost to follow-up, so data for 23 participants were used in the complete-case analysis. For the injured leg, the mean (SD) decrease in maximal strength from PRE to POST was significantly lower for the vibration than control group (n = 11, ?16% [10] vs. n = 12, ?30% [11]; P = 0.0045, Cohen's d effect size = 1.33). Mean PRE–POST change in limb symmetry was lower for the vibration than control group (?19% [11] vs. ?29% [13]) but not significantly (P = 0.051, Cohen's d effect size = 0.85).ConclusionLVT improved strength recovery after ACLR. This feasibility study suggests that LVT applied to relaxed muscles is a promising modality of vibration therapy that could be implemented early in ACLR.Trial registrationClinicalTrials.gov: NCT02929004.     

Changes in health-related quality of life may predict recurrent breast cancer

BackgroundPatient-reported outcomes incorporated in cancer clinical trials, are increasingly hypothesized to be predictors of disease-free survival. Previous research supports health-related quality of life (HRQoL) as an independent predictor of survival in patients with advanced or metastatic breast cancer. In contrast, recent studies provide evidence that baseline HRQoL scores are not associated with increased risk of relapse or survival in women with early-stage breast cancer. One plausible assumption might be that baseline HRQoL scores are limited as predictors of a recurrence of breast cancer several years after the initial diagnosis. In this explorative study, we examined whether changes in HRQoL over time may predict breast cancer recurrence. As a supplement, we investigated whether baseline HRQoL predicted recurrence.MethodsThe study sample consisted of 141 participants in the International Breast Cancer Study Group adjuvant Trial 12-93 and Trial 14-93, from the Western region of Sweden. HRQoL was assessed, during a 5-year follow up. Poisson regression analysis was used to estimate the hazard function of recurrence depending on time since primary diagnosis and on HRQoL variables.ResultsAccording to the Poisson multivariable regression analysis changes in physical well-being (β = 0.00439, p-value = 0.0470), and nausea/vomiting (β = ?0.00612, p-value = 0.0136) significantly predicted recurrence. Baseline HRQoL outcomes were not predictors of recurrence.ConclusionsChanges of HRQoL during adjuvant therapy may be associated with recurrence. This explorative finding needs prospective investigation.     

Survival after Public Access Defibrillation in Stockholm,Sweden – A striking success

BackgroundIn Stockholm, a first responder system and a Public Access Defibrillation (PAD) program has been implemented. Additionally, the number of “unregulated” public Automated External Defibrillators (AEDs) sold “over-the-counter” has increased. The aim of this study was to evaluate the impact on survival from different defibrillation strategies in cases of out-of-hospital cardiac arrest (OHCA) available for PAD.Methods and ResultsDesign: Retrospective study of all OHCAs in Stockholm, 2006–2012. Witnessed OHCAs occurring outside home with cardiac origin and ventricular fibrillation were considered subjects for PAD. The sites within the PAD program increased from 60 to 135 while the number of unregulated AEDs outside the PAD program increased from 178 to 5016.Of 6532 OHCAs, 7% (n = 474) were defined as subjects for PAD. Of these, 69% (n = 326) were defibrillated by the EMS, 11% (n = 53) by first responders and 16% (n = 74) by public AEDs. Survival to one month was 31% (n = 101) for cases defibrillated by the EMS, 42% (n = 22) when defibrillated by first responders and 70% (n = 52) when defibrillated by a public AED. The AEDs within the PAD program constituted 2.6% of all public AEDs and were used in 28% (n = 21) of cases when a public AED was used.ConclusionsIn OHCAs available for PAD, 70% of patients survived if a public AED was used. Both the structured AED program as well as the spread of unregulated AEDs was associated with very high survival rates, but the structured approach was more efficient in relation to the number of AEDs used.     

Traditional Chinese Medicine treatment as maintenance therapy in advanced non-small-cell lung cancer: A randomized controlled trial

ObjectivesMaintenance therapy for patients with advanced non-small-cell lung cancer (NSCLC) is an increasingly hot topic in the field of clinical NSCLC research. This study aimed to evaluate the effects of Traditional Chinese Medicine (TCM) treatment as maintenance therapy on time to progression (TTP), quality of life (QOL), overall survival (OS) and 1-year survival rate in patients with advanced NSCLC.MethodsThis study was conducted as a randomized, controlled, open-label trial. 64 non-progressive patients who responded to initial therapy were randomized 1:1 to the TCM arm (treated with herbal injection (Cinobufacini, 20 ml/d, d1–d10), herbal decoction (d1–d21) and Chinese acupoint application (d1–d21), n = 32) or to the chemotherapy arm (treated with pemetrexed (non-squamous NSCLC, 500 mg/m², d1), docetaxel (75 mg/m², d1) or gemcitabine (1250 mg/m², d1 and d8), n = 32). Each therapy cycle was 21 days. They were repeated until disease progression, unacceptable toxicity, or until the patients requested therapy discontinuation. The primary end point was TTP; the secondary end points were QOL, OS and 1-year survival rate. “Intention-to-treat” analysis included all randomized participants.ResultsTCM treatment prolonged median TTP for 0.7 months compared with chemotherapy, but it was not statistically significant (3.0 months vs. 2.3 months, P = 0.114). Median OS time for TCM treatment did not offer a significant advantage over for chemotherapy (21.5 months vs. 18.8 months, P = 0.601). 1-year survival rate of TCM treatment significantly improved than that of chemotherapy (78.1% vs. 53.1%, P = 0.035). TCM treatment can significantly improve QOL when compared to chemotherapy as assessed by EORTC QLQ-C30 and EORTC QLQ-LC13 QOL instruments.ConclusionsTCM maintenance treatment had similar effects on TTP and OS compared with maintenance chemotherapy, but it improved patients' QOL and had higher 1-year survival rate. TCM Maintenance treatment is a promising option for advanced NSCLC patients without progression following first-line chemotherapy.     

Effect of a high-intensity interval training on serum microRNA levels in women with breast cancer undergoing hormone therapy. A single-blind randomized trial

BackgroundThe role of microRNAs (miRs) in hormone therapy (HT) is of keen interest in developing biomarkers and treatments for individuals with breast cancer. Although miRs are often moderate regulators under homeostatic conditions, their function is changed more in response to physical activity.ObjectiveThis single-blind randomized trial aimed to explore the effect of high-intensity interval training (HIIT) on serum levels of miRs in individuals with early-stage breast cancer undergoing HT.MethodsHormone receptor-positive women with breast cancer and healthy women were randomly assigned to a healthy control group (n = 15), healthy group with HIIT (n = 15), breast cancer group with HT (HT, n = 26), and breast cancer group with HT and HIIT (HT + HIIT, n = 26). The exercise groups underwent interval uphill walking training on a treadmill 3 times a week for 12 weeks. At the end of the study, we analyzed changes in levels of cancer-related miRs (oncomiRs) and tumour suppressor miRs (TSmiRs) in response to the HT and HIIT.ResultsIn women with breast cancer versus healthy controls, the expression of some oncomiRs was significantly increased — miR-21 (P < 0.001), miR-155 (P = 0.001), miR-221 (P = 0.008), miR-27a (P < 0.001), and miR-10b (P = 0.007) — and that of some TSmiRs was significantly decreased — miR-206 (P = 0.048), miR-145 (P = 0.011), miR-143 (P = 0.008), miR-9 (P = 0.020), and let-7a (P = 0.005). Moreover, HT considerably downregulated oncomiRs and upregulated TSmiRs. HIIT for 12 weeks with HT significantly decreased the expression of the oncomiRs and significantly increased that of the TSmiRs as compared with HT alone.ConclusionsHITT could amplify the decrease and/or increase in expression of miRs associated with HT in women with breast cancer. A prospective trial could determine whether the use of circulating miRs for monitoring treatment can be useful in therapy decisions.Trial registrationIranian Registry of Clinical Trials (No.: IRCT201202289171N1).     

Crenobalneotherapy (spa therapy) in patients with knee and generalized osteoarthritis: A post-hoc subgroup analysis of a large multicentre randomized trial

ObjectiveTo determine whether the addition of spa therapy to home exercises provides any benefit over exercises and the usual treatment alone in the management of generalised osteoarthritis associated with knee osteoarthritis.MethodsThis study was a post-hoc subgroup analysis of our randomised multicentre trial (www.clinicaltrial.gov: NCT00348777). Participants who met the inclusion criteria of generalized osteoarthritis (Kellgren, American College of Rheumatology, or Dougados criteria) were extracted from the original randomised controlled trial. They had been randomised using Zelen randomisation. The treatment group received 18 days of spa treatment in addition to a home exercise programme. Main outcome was number of patients achieving minimal clinically important improvement at six months (MCII) (≥ −19.9 mm on the VAS pain scale and/or ≥ −9.1 points in a WOMAC function subscale), and no knee surgery. Secondary outcomes included the “patient acceptable symptom state” (PASS) defined as VAS pain ≤ 32.3 mm and/or WOMAC function subscale ≤ 31 points.ResultsFrom the original 462 participants, 214 patients could be categorized as having generalised osteoarthritis. At sixth month, 182 (88 in control and 94 in SA group) patients, were analysed for the main criteria. MCII was observed more often in the spa group (n = 52/94 vs. 38/88, P = 0.010). There was no difference for the PASS (n = 19/88 vs. 26/94, P = 0.343).ConclusionsThis study indicates that spa therapy with home exercises may be superior to home exercise alone in the management of patients with GOA associated with knee OA.     

Adjunct therapies after botulinum toxin injections in spastic adults: Systematic review and SOFMER recommendations

BackgroundAdjunct therapies (ATs) may further improve outcomes after botulinum toxin injections in spastic patients, but evidence was unclear in previous systematic reviews.ObjectiveTo assess the efficacy of non-pharmacological ATs in spastic adults according to the International Classification of Functioning, Disability and Health and build an expert consensus-based on a Delphi process.MethodsFour electronic databases were searched up to May 2020 for reports of comparative trials of non-pharmacologic ATs after botulinum toxin injections in spastic adults. Then, 25 French experts participated in a two-round Delphi process to build recommendations on the use of ATs.ResultsWe included 32 studies (1202 participants, median 32/study) evaluating the effects of physical agents (n = 9), joint posture procedures (JPPs, n = 11), and active ATs (n = 14), mainly after stroke. The average quality of articles was good for randomised controlled trials (median [interquartile range] PEDro score = 7 [6–8]) but moderate (n = 2) or poor (n = 2) for non-randomised controlled trials (Downs & Black checklist). Meta-analysis was precluded owing to the heterogeneity of ATs, control groups and outcome measures. There is evidence for the use of JPPs except low-dose manual stretching and soft posture techniques. Continuous postures (by taping or casting) are recommended; discontinuous postures (by orthosis) may be preferred in patients with active function. Device-free or device-assisted active ATs may be beneficial in the mid-term (> 3 months after botulinum toxin injections), particularly when performed at a high-intensity (> 3 h/week) as in constraint-induced movement therapy. Self-rehabilitation remains understudied after a focal treatment, but its interest is highlighted by the experts. The use of physical agents is not recommended.ConclusionsJPPs and active ATs (device-assisted or device-free) may further improve impairments and activities after botulinum toxin injections. Further studies are needed to better define the best strategies for ATs as a function of the individual treatment goals, participation and quality of life.Review RegistrationPROSPERO (CRD42018105856).     

Diagnostic and prognostic potentials of microRNA-27a in osteosarcoma

AimGrowing evidence suggest that the microRNA (miR)-23a/24-2/27a cluster may play a crucial role in mammary tumorigenesis and act as a novel class of oncogenes. Among these members, miR-27a has been reported to promote proliferation, migration and invasion in human osteosarcoma cells. The aim of this study was to detect the serum levels of miR-27a in osteosarcoma patients and to investigate its associations with clinicopathological features and prognosis.MethodsmiR-27a levels in sera from 166 osteosarcoma patients and 60 healthy controls were detected by real-time quantitative RT-PCR. Then, the associations of serum miR-27a level with clinicopathological factors or survival of osteosarcoma patients were further evaluated.ResultsCompared to healthy controls, the serum levels of miR-27a were significantly increased in osteosarcoma patients (P < 0.001). Importantly, miR-27a could efficiently screen osteosarcoma patients from healthy controls (Area under receiver operating characteristic curve, AUC = 0.867). Then, high miR-27a expression was more frequently occurred in osteosarcoma patients with advanced clinical stage (P = 0.001), positive distant metastasis (P = 0.01) and poor response to chemotherapy (P = 0.008). In Kaplan–Meier survival analysis, high miR-27a expression was a significant indicator for poor overall survival (P = 0.006) as well as poor disease-free survival (P = 0.01). Furthermore, multivariate analysis demonstrated that miR-27a expression was an independent and significant prognostic factor to predict overall survival (P = 0.01) and disease-free survival (P = 0.03).ConclusionmiR-27a expression may be elevated in sera of osteosarcoma patients and in turn contributes to aggressive progression of this malignancy. Detection of serum miR-27a levels may have clinical potentials as a non-invasive diagnostic/prognostic biomarker for osteosarcoma patients.     

Impact of a stand-alone course in gerontological nursing on undergraduate nursing students' perceptions of working with older adults: A Quasi-experimental study

BackgroundWith an aging population, it is critical that nurses are educated and prepared to offer quality healthcare to this client group. Incorporating gerontology content into nursing curricula and addressing students' perceptions and career choices in relation to working with older adults are important faculty concerns.ObjectivesTo examine the impact of a stand-alone course in gerontological nursing on undergraduate nursing students' perceptions of working with older adults and career intentions.DesignQuasi-experimental, pre- and post-test design.SettingMedium-sized state university in the Mid Western United StatesParticipantsData were collected from three student cohorts during the spring semesters of 2012 (n = 98), 2013 (n = 80) and 2014 (n = 88) for a total of N = 266 with an average response rate of 85%.MethodsA survey instrument was administered via Qualtrics and completed by students prior to, and following completion of the course.ResultsThere was an overall significant increase (p = 0.000) in positive perceptions of working with older adults among nursing students following completion of the course. The majority of participants (83.5%) reported having previous experience with older adults. Those with previous experience had higher perception scores at pre-test than those without (p = 0.000). Post-test scores showed no significant difference between these two groups, with both groups having increased perception scores (p = 0.120). Student preferences for working with different age groups suggested an overall increase in preference for working with older adults following the course.ConclusionsA course in gerontological nursing, incorporating learning partnerships with community dwelling older adults, promotes positive perceptions of working with older adults, independently of the quality of prior experience. There was some evidence that students changed their preferences of working with different age groups in favor of working with older adults. Further research should be conducted to determine the mechanisms through which this takes place.     

Structured training in the management of emergencies in mothers,babies and children in a poorly resourced health system: Logbooks to document skill use

ObjectiveTo evaluate the use of a structured training programme in emergency care in Pakistan through the completion of logbooks documenting actual resuscitation attempts.DesignCross-sectional survey.SettingAll tiers of health care settings across all regions of Pakistan.Participants120 health workers, trained in the skills for managing maternal, neonatal and childhood emergencies as part of a system development programme called “Essential Surgical Skills–Emergency Maternal and Child Healthcare (ESS–EMCH).MethodsFollowing a series of 6 five-day training courses developed as part of the ESS–EMCH programme between January and December 2006, participants were provided with logbooks to document the actual use of their newly acquired skills during the resuscitation of mothers, infants and children.Results1123 resuscitation attempts were documented and received from 63 of the 120 participants (response rate 53%; number of forms 4–22 per participant). Seventy-six percent (858/1123) of documented cases were received from doctors and 24% (265) from nurses. The patients receiving resuscitation were neonates 31% (n = 349), infants and children 38% (n = 426), pregnant mothers 21% (n = 233) and other adults 10% (n = 111). The commonest emergencies treated in neonates were resuscitation at birth, sepsis, shock and difficulty in breathing. Haemorrhage was the commonest obstetric emergency (52%, n = 52/101), followed by eclampsia and shoulder dystocia. Skills used to secure the airway; breathing (use of oxygen and bag valve mask ventilation) and circulation were used in 58%, 82% and 73% of resuscitated patients. Oxygen was used in 87% of neonates and in 62% of pregnant mothers. The overall survival rate in the cases reported was 89%.ConclusionsResuscitation logbooks can be used to assess which skills are used in emergency care. This analysis provides some evidence that the skills taught during the ESS–EMCH programme are used by the trained health workers. Individually held and completed logbooks should continue to act as a feedback and audit mechanism to measure outcomes, in conjunction with other methods of evaluating the impact of the training component of this programme.     

Process evaluation of physical activity counselling with and without the use of mobile technology: A mixed methods study

BackgroundA monitoring-and-feedback tool was developed to stimulate physical activity by giving feedback on physical activity performance to patients and practice nurses. The tool consists of an activity monitor (accelerometer), wirelessly connected to a Smartphone and a web application. Use of this tool is combined with a behaviour change counselling protocol (the Self-management Support Programme) based on the Five A's model (Assess–Advise–Agree–Assist–Arrange).ObjectivesTo examine the reach, implementation and satisfaction with the counselling protocol and the tool.DesignA process evaluation was conducted in two intervention groups of a three-armed cluster randomised controlled trial, in which the counselling protocol was evaluated with (group 1, n = 65) and without (group 2, n = 66) the use of the tool using a mixed methods design.SettingsSixteen family practices in the South of the Netherlands.ParticipantsPractice nurses (n = 20) and their associated physically inactive patients (n = 131), diagnosed with Chronic Obstructive Pulmonary Disease or Type 2 Diabetes, aged between 40 and 70 years old, and having access to a computer with an Internet connection.MethodsSemi structured interviews about the receipt of the intervention were conducted with the nurses and log files were kept regarding the consultations. After the intervention, questionnaires were presented to patients and nurses regarding compliance to and satisfaction with the interventions. Functioning and use of the tool were also evaluated by system and helpdesk logging.ResultsEighty-six percent of patients (group 1: n = 57 and group 2: n = 56) and 90% of nurses (group 1: n = 10 and group 2: n = 9) responded to the questionnaires. The execution of the Self-management Support Programme was adequate; in 83% (group 1: n = 52, group 2: n = 57) of the patients, the number and planning of the consultations were carried out as intended. Eighty-eight percent (n = 50) of the patients in group 1 used the tool until the end of the intervention period. Technical problems occurred in 58% (n = 33). Participants from group 1 were significantly more positive: patients: χ²(2, N = 113) = 11.17, p = 0.004, and nurses: χ²(2, N = 19) = 6.37, p = 0.040. Use of the tool led to greater awareness of the importance of physical activity, more discipline in carrying it out and more enjoyment.ConclusionsThe interventions were adequately executed and received as planned. Patients from both groups appreciated the focus on physical activity and personal attention given by the nurse. The most appreciated aspect of the combined intervention was the tool, although technical problems frequently occurred. Patients with the tool estimated more improvement of physical activity than patients without the tool.     

Structured scoring of supporting nursing tasks to enhance early discharge in geriatric rehabilitation: The BACK-HOME quasi-experimental study

IntroductionIn geriatric rehabilitation it is important to have timely discharge of patients, especially if they have low nursing support needs. However, no instruments are available to identify early discharge potential.ObjectiveTo evaluate if weekly scoring of a nursing support scorecard in the evenings/nights and discussing the results in the multidisciplinary team meeting, leads to potential differences in discharge of geriatric rehabilitation patients.DesignQuasi-experimental study with a reference cohort (n = 200) and a Back-Home implementation cohort (n = 283).Setting/ParticipantsPatients in geriatric rehabilitation in the four participating skilled nursing facilities in the Netherlands.MethodsImplementation of the nursing support scorecard during one year consisted of (1) weekly scoring of the scorecard to identify the supporting nursing tasks during the evenings/nights by trained nurses, and (2) discussion of the results in a multidisciplinary team meeting to establish if discharge home planning was feasible. Data on patients’ characteristics and setting before admission were collected at admission; at discharge, the length of stay, discharge destination and barriers for discharge were collected by the nursing staff.ResultsBoth cohorts were comparable with regard to median age, gender [reference cohort: 81 (IQR 75–88) years; 66% females vs. Back-Home cohort 82 (IQR 76–87) years; 71% females] and reasons for admission: stroke (23% vs. 23%), joint replacement (12% vs. 13%), traumatic injuries (31% vs. 34%), and other (35% vs. 30%). Overall, the median length of stay for the participants discharged home in the reference cohort was 56 (IQR 29–81) days compared to 46 (IQR 30–96) days in the Back-Home cohort (p = 0.08). When no home adjustments were needed, participants were discharged home after 50 (IQR 29.5–97) days in the reference cohort, and after 42.5 (IQR 26–64.8) days in the Back-Home cohort (p = 0.03). Reasons for discharge delay were environmental factors (36.7%) and patient-related factors, such as mental (21.5%) and physical capacity (33.9%).ConclusionStructured scoring of supporting nursing tasks for geriatric rehabilitation patients may lead to earlier discharge from a skilled nursing facility to home, if no home adjustments are needed.     

Cancer-Related Symptom Clusters,Eosinophils, and Survival in Hepatobiliary Cancer: An Exploratory Study

ContextThe study of symptom clusters is gaining increased attention in the field of oncology in an attempt to improve the quality of life of patients diagnosed with cancer.ObjectivesThe aims of the present study were to 1) determine the prevalence and distribution of pain, fatigue, and symptoms of depression and their covariation as a cluster in people with hepatobiliary carcinoma (HBC), 2) characterize how variation in each individual symptom and/or their covariation as a cluster are associated with changes in immunity, and 3) determine if the symptom clusters, and associated biomarkers, are related to survival in people diagnosed with HBC.MethodsTwo hundred six participants diagnosed with HBC completed a battery of standardized questionnaires measuring cancer-related symptoms. Peripheral blood leukocytes were measured at diagnosis and at three- and six-month follow-ups. Survival was measured from the date of diagnosis to death.ResultsCancer-related symptoms were prevalent and two-step hierarchical cluster analyses yielded three symptom clusters. High levels of pain, fatigue, and depression were found to be associated with elevated eosinophil percentages (F[1,78] = 3.1, P = 0.05) at three- and six-month follow-up using repeated-measures analysis of variance. Using multivariate latent growth curve modeling, pain was the primary symptom associated with elevated eosinophil percentages between diagnosis and six months (z = 2.24, P = 0.05). Using Cox regression, vascular invasion and age were negatively associated with survival (Chi-square = 21.6, P = 0.03). While stratifying for vascular invasion, Kaplan-Meier survival analysis was performed, and eosinophil levels above the median for the sample were found to be related to increased survival in patients with and without vascular invasion (Breslow Chi-square = 4.9, P = 0.03). Symptom clusters did not mediate the relationship between eosinophils and survival.ConclusionCancer-related symptoms, particularly pain and depression, were associated with increased percentages of eosinophils. The presence of symptoms may reflect tumor cell death and be indicative of response to treatment, or other processes, in patients with HBC.     

Prevalence of systemic air-embolism after prolonged cardiopulmonary resuscitation in newborns: A pilot study

BackgroundChest compressions (CC) during cardiopulmonary resuscitation (CPR) are the cornerstone of adult CPR protocols and are meant to restore circulation and improve outcome. Although adverse effects such as air-embolisms have been reported, these are rare and considered to be outweighed by beneficial effect. In newborns, however, the lung tissue is more fragile. Thus, the high intra-thoracic pressures resulting from CC may make the newborns more vulnerable for air-embolisms.ObjectivesWe studied the postmortem prevalence of air-embolism in neonates that have received CPR.MethodsProspective cohort analysis of newborns receiving CC during CPR. CPR was performed by trained staff according to ILCOR guidelines, in a tertiary hospital. Air-embolisms were sought after using CT/MRI and autopsy.ResultsDuring a 61/2 year period (2007–2014), n = 56 newborns received CC. Newborns were resuscitated following severe perinatal hypoxia, or due to complications during NICU treatment. In n = 14 (25.0%) circulation could not be restored (mean CPR duration: 32.7 ± 15.2 min). Post-mortem CT/MRI was performed in n = 9, of whom n = 8 (88.9%) had air-embolisms. Autopsy was performed in n = 9. The air-embolisms could not be retraced on autopsy except for n = 1 patient.In patients with CPR resulting in restored circulation (n = 42), no CT or MRI was performed for comparison due to radiation and/or hemodynamic instability. Cerebral ultrasound could not identify or exclude air-embolisms in this subgroup.ConclusionsPost-mortem CT after prolonged resuscitation showed a high prevalence of intravascular air-embolism. Autopsy was not suited to detect air-embolism. The clinical importance of air-embolisms on the lethal outcome needs further research.     

Correlations of creatine and six related pyrimidine metabolites and diabetic nephropathy in Chinese type 2 diabetic patients

ObjectivesThe assessment of the clinical significance of creatine, cytosine, cytidine, uridine, thymine, thymidine, and 2′-deoxyuridine concentrations in patients with type 2 diabetes mellitus (T2DM) and diabetic nephropathy (DN) for the detection of the relationship between pyrimidine metabolites and disease.Design and methodsThe study group consisted of 119 subjects, which were divided to three groups: control (n = 31), type 2 diabetes without nephropathy (DM, n = 23), and with nephropathy (DN, n = 65). Levels of related metabolites were measured in plasma of all participants.ResultsThere is a significant increase in levels of cytosine (P < 0.001), cytidine (P < 0.001), and thymidine (P = 0.016) with DN compared to DM. The levels of uridine, thymine, 2′-deoxyuridine, and creatine did not change.ConclusionsThe levels of cytosine, cytidine, and thymidine may be useful for monitoring the progression of DM and evaluating the treatment.     

The association of gasping and outcome,in out of hospital cardiac arrest: A systematic review and meta-analysis

ObjectiveGasping is common after cardiac arrest, and its frequency decreases over time. The aim of this study was to conduct a meta-analysis to evaluate the association of gasping and survival to discharge in patients who suffered out-of-hospital cardiac arrest.MethodsRelevant studies were identified by searching in PubMed, Medline, Embase, OVID, Web of Science and Google Scholar. Risk ratios (RR) and 95% confidence intervals (CI) were calculated to assess the association of gasping and on out-of-hospital cardiac arrest outcomes. Heterogeneity, subgroup analysis, sensitivity analysis and publication bias were explored.ResultsIndividual patient data was obtained from 10,797 participants suffered out-of-hospital cardiac arrest in five cohort studies of 4 articles. A fixed effects model suggested that patients with gasping were 3.525 times (95% CI: 3.028–4.104; P < 0.01) more likely to survive to discharge than those without gasping, and there was no heterogeneity among studies (P = 0.564). Also it may be a favorable factor for return of spontaneous circulation (RR: 2.170; 95% CI: 1.691, 2.785) with high heterogeneity (Q = 5.26; P = 0.022).ConclusionsFindings of this meta-analysis demonstrated that gasping is common after cardiac arrest, and is associated with increased survival to discharge. Patients who are cardiac arrest with gasping should be promptly resuscitated.     

BCL2L12: A promising molecular prognostic biomarker in breast cancer

ObjectivesBCL2-like 12 (BCL2L12) is a new member of the BCL2 gene family that was discovered and cloned by members of our group and found to be expressed in the mammary gland. Many genes of the BCL2 family were found to be implicated in breast carcinogenesis and to serve as possible prognostic markers. The aim of the present study was the quantification of BCL2L12 mRNA expression in order to assess its value as a prognostic tissue biomarker in breast cancer (BC).Design and methodsBCL2L12 mRNA levels were determined in a statistically significant sample size of cancerous (N = 108) and adjacent non-cancerous (N = 71) breast tissues using a highly sensitive quantitative real-time polymerase chain reaction (qRT-PCR) method. Relative quantification analysis was conducted using the comparative C_T (2^− ΔΔC_T) method, whereas the association between BCL2L12 expression and clinopathological data, disease-free survival (DFS) and overall survival (OS) were estimated by statistical analysis.ResultsBCL2L12 mRNA expression was decreased in malignant samples compared to the histologically normal counterparts (p = 0.012). Significant relationships between BCL2L12 expression and TNM stages (p = 0.009), metastatic potential (p = 0.012), tumor size (p = 0.04) and age (p = 0.024) were observed. Moreover, Kaplan–Meier and Cox univariate analyses indicated that BCL2L12 expression is associated with longer DFS, whereas multivariate analysis pointed out the independent favorable prognostic value of BCL2L12.ConclusionsAccording to our results, BCL2L12 mRNA expression is a favorable prognostic marker of DFS for BC patients, suggesting its possible application as a novel prognostic indicator of this malignancy.     

Seated Tai Chi versus usual activities in older people using wheelchairs: A randomized controlled trial

ObjectiveCompare the effect of seated Tai Chi exercise (intervention) to usual activities on quality of life and depression symptoms in older people using wheelchairs.DesignRandomized controlled trial.SettingOne long-term care facility in Taiwan.Participants86 long-term care residents were screened; 60 were eligible and randomized to Tai Chi group (n = 30), or usual activity (n = 30).InterventionOne certified trainer provided the intervention group with 40 min of seated Tai Chi exercise, three times a week for 26 weeks. Trial registration ACTRN12613000029796.Main outcome measuresQuality of Life (WHOQOL (BREF)); depression symptoms (GDS-SF)ResultsParticipants in the Tai Chi group (M = 3.76, SD = 3.65) recorded significantly lower GDS-SF scores than participants in the control (M = 7.76, SD = 5.15) and the Tai Chi group registered significantly higher scores across overall QOL [p = 0.03], general health [p = 0.04], and the associated domains: physical health [p = 0.00], psychological health [p = 0.02], social relations [p = 0.00], and environment [p = 0.00].ConclusionsThe findings highlight the importance of Tai Chi in improving QOL and depression in this population.     

Serum Retinol-Binding Protein 4 (RBP4) and retinol in a cohort of borderline obese women with and without gestational diabetes

ObjectivesTo evaluate whether serum RBP4 correlates with gestational diabetes mellitus (GDM) in a cohort of borderline obese (BMI > 30) pregnant women.Design and methodsSerum RBP4 and retinol were measured in pregnant women with (n = 12) and without (n = 10) GDM.ResultsRBP4, retinol and RBP4:retinol molar ratio were not different between the groups and were not associated with markers of insulin resistance.ConclusionsGDM is not associated with RBP4 or retinol among borderline obese pregnant women.
