Introduction: Although many reports have analyzed the outcomes of central venous catheters (CVCs) in oncologic and oncohematologic patients, current guidelines do not routinely recommend a specific type of CVC over the other. Methods: We retrospectively evaluated the outcomes of 178 patients with CVCs referred to an Italian specialized cancer center between January 2016 and December 2018. The analysis compares midterm peripherally inserted central venous catheters (PICCs) with long-term centrally inserted catheters, including totally implanted ports and tunneled catheters with central insertion (tCVCs). Results: A total of 130 PICCs (73%) and 48 tCVCs (27%) were analyzed. The overall complication rate was significantly increased in the PICC cohort compared to the tCVC cohort (43.1% vs 25%, respectively; p = 0.037), leading to complication-related device removal in 30.8% of PICCs vs 12.5% of tCVCs ( p = 0.013). No significant differences in terms of catheter-related thromboses ( p = 0.676) or catheter-related infections ( p = 0.140) were detected. Nonthrombotic obstructions were significantly higher in the PICC group compared to the tCVC cohort ( p = 0.006). Overall complication-free survival was significantly longer for tCVCs compared to PICCs (hazard ratio [HR], 0.262; 95% confidence interval [CI], 0.128–0.536; p < 0.0001), as well as obstruction-free survival (HR, 0.082; 95% CI, 0.018–0.372; p < 0.0001). In multivariable analysis, the type of CVC was independently correlated with the occurrence of any complication (HR, 0.273; 95% CI, 0.135–0.553; p < 0.0001). Conclusions: This Italian real-world experience suggests that PICCs are associated with a higher risk of overall complications compared with tCVCs. Catheter choice in oncologic patients should be guided by treatment type and duration, risk–benefit assessment, patient preferences, and compliance.
How ordinary child language acquisition processes can lead to the unusual outcome of a mixed language
Authors: O’Shannessy Carmel 
Published: June 2020

Aims and Objectives: The aim of this study is to examine the language processing mechanisms involved when young children bring structural innovations into their community way of speaking, as part of conventionalising code-switching practices to become a mixed language. Approach: The study takes a qualitative approach to the analysis of child language acquisition and adult speech data in two contexts. Data and Analysis: The study analyses naturalistic and spontaneous speech data of children and adults speaking the mixed language, Light Warlpiri, and adults older than that age group who do not speak the new mixed language. It compares an innovative auxiliary form in Light Warlpiri to child non-target speech in English with data taken from the Child Language Data Exchange System corpus. Findings: The findings are that the Light Warlpiri-speaking children used processes of re-analysis that are commonly found in child first language acquisition in other contexts to re-analyse elements of the verbal input, but because of the sociolinguistic context they created an innovative structure. Originality: The study is the first to directly compare processes of innovation in language contact with those of non-target structures in monolingual child language acquisition, identifying the same processes in each. It is also the first to show that a dramatic structural change from a linguistic perspective may be a small, incremental change from a child learner’s perspective. Significance/Implications: The significance of the study is that until now processes of innovation in language contact situations have been thought by many to differ in quality from those in monolingual child language acquisition contexts. This study shows that the child language acquisition processes are the same in each situation, but different sociolinguistic contexts lead to different outcomes for the communities’ ways of speaking. It also shows that children do not bring in new structure that is not motivated by their input; rather, they make small changes to the input they receive.
MicroRNA-96-5p Facilitates the Viability, Migration, and Invasion and Suppresses the Apoptosis of Cervical Cancer Cells byNegatively Modulating SFRP4

Published: June 2020

Purpose: The current study was intended to research the functional role and regulatory mechanism of microRNA-96-5p in the progression of cervical cancer. Methods: MicroRNA-96-5p expression in cervical cancer tissues was assessed by quantitative real-time polymerase chain reaction. The association between microRNA-96-5p expression and clinicopathological features of patients with cervical cancer was analyzed. MTT, flow cytometry, wound healing, and transwell assay were performed to evaluate the viability, apoptosis, migration, and invasion of Hela and SiHa cells. Targetscan, dual-luciferase reporter gene assay, and RNA pull-down analysis were constructed to evaluate the target relationship between microRNA-96-5p and secreted frizzled-related protein 4. Results: MicroRNA-96-5p was overexpressed in cervical cancer tissues, and microRNA-96-5p expression was markedly associated with the clinical stage and lymph node metastasis of patients with cervical cancer. Overexpressed microRNA-96-5p facilitated the viability, migration, invasion, and inhibited the apoptosis of Hela and SiHa cells, whereas suppression of microRNA-96-5p exerted the opposite trend. Secreted frizzled-related protein 4 was proved to be a target of microRNA-96-5p. Silencing of secreted frizzled-related protein 4 eliminated the anti-tumor effect of microRNA-96-5p on cervical cancer cells. Conclusions: MicroRNA-96-5p facilitated the viability, migration, and invasion and inhibited the apoptosis of cervical cancer cells via negatively regulating secreted frizzled-related protein 4.
Analysis of the impact of secondary prophylaxis on Clostridioides difficile recurrence in critically ill adults
Authors: Connor Kathryn A , Conn Kelly M 
Published: June 2020

Introduction: Clostridioides (formerly Clostridium) difficile infection recurrence in patients re-exposed to antibiotics for treatment of a non- Clostridioides difficile infection is high at approximately 33%. Low-dose per os vancomycin (e.g. 125 mg q12 h) or metronidazole (e.g. 500 mg intravenous/per osq8 h) may help prevent recurrences, but study of secondary prophylaxis in critically ill patients is needed. Objectives: To determine whether critically ill adults receiving low-dose per os vancomycin for secondary Clostridioides difficile infection prophylaxis have fewer recurrences of Clostridioides difficile infection in 90 days compared with patients receiving metronidazole for secondary Clostridioides difficile infection prophylaxis or control (no secondary prophylaxis). Methods: This was a retrospective, two-center, observational study in a large academic medical center and affiliated community hospital. Included patients had a history of Clostridioides difficile infection within 1 year of receiving antibiotics for clinical care. We compared patients receiving secondary prophylaxis with vancomycin or metronidazole and control patients; in addition, an unplanned fourth group (vancomycin/metronidazole combination) was identified and analyzed. The primary outcome was Clostridioides difficile infection recurrence within 90 days of a course of broad-spectrum antibiotic therapy. Fisher’s exact, analysis of variance, and Kruskal–Wallis tests were used to compare Clostridioides difficile infection recurrence with prophylaxis group and additional contributing factors. Results: Eighty-two patients were included: 38 control (46.3%), 20 metronidazole (24.4%), 17 vancomycin (20.7%), and 7 combination (8.5%). Ten of 82 patients (12.2%) had at least one Clostridioides difficile infection recurrence; 8/38 patients in the control group (21.1%), 1/7 patients in the combination group (14.3%), 1/17 patients in the per os vancomycin group (5.9%), and 0/20 in the metronidazole group (0%; p = 0.073). As a post hoc secondary analysis, the three prophylaxis groups were coalesced into one group and compared with control (4.5% vs 21%; p = 0.039). Additional factors (e.g. age, obesity, immunosuppression, acid suppression) were not significantly associated with Clostridioides difficile infection recurrence or with prophylaxis group. Conclusion: There was no difference in Clostridioides difficile infection recurrence between prophylaxis groups, however, given the low recurrence rate, prospective evaluation with a larger sample of critically ill patients is necessary.
Features of YouTube™ videos produced by individuals who self-identify with borderline personality disorder
Authors: Woloshyn Vera , Savage Michael J 
Published: June 2020

Objectives Many individuals use YouTube™ to seek out information and share first-hand experiences about mental illnesses, as well as to gain a sense of community. YouTube™ use may be especially appealing when offline supports are lacking or difficult to access, and when there is a fear of stigmatisation. Borderline personality disorder (BPD), also referred to as emotionally unstable personality disorder (EUPD), is a complex and often stigmatised mental-health disorder. The primary objective of this study was to describe the dominant messages that individuals who self-identify with the diagnosis of BPD present through YouTube™ videos. Methods The content analysis method was used to review 349 first-person YouTube™ uploads. Videos were coded for information regarding video and vlogger characteristics, video type, vlogger motivation and video content. Associations between video features including upload date and style and vlogger experience and motivation were examined. Results Findings indicate that more people who self-identify as being diagnosed with BPD are creating YouTube™ videos about their experiences, and these videos have shifted over time from being mostly anonymous multimedia productions to being monologues where the vlogger speaks directly to their audience. Discussions related to DSM-5 symptoms, treatment, effective coping and hope for the future are elements found in the uploads. Conclusion The nature and content of BPD first-person YouTube™ uploads has increased and changed over time. Increased awareness of these changes may assist mental-health practitioners to support clients and direct them to explore uploads that offer hope and promote engagement in help-seeking and effective coping behaviours.

Abstract
Background
To investigate the species distribution of non-tuberculous mycobacteria (NTM) among tuberculosis (TB) specimens collected from January 2013 to December 2018 at Peking Union Medical Hospital (Beijing), China. NTM species identification was carried out by DNA microarray chip.

Results
Mycobacterial species were detected in 1514 specimens from 1508 patients, among which NTM accounted for 37.3% (565/1514), increasing from a proportion of 15.6% in 2013 to 46.1% in 2018 (P < 0.001). Among the 565 NTM positive specimens, the majority (55.2%) were from female patients. Furthermore, patients aged 45–65 years accounted for 49.6% of the total patients tested. Among 223 NTM positive specimens characterized further, the majority (86.2%) were from respiratory tract, whilst 3.6 and 3.1% were from lymph nodes and pus, respectively. Mycobacterium intracellulare (31.8%) and Mycobacterium chelonae / Mycobacterium abscessus (21.5%) were the most frequently detected species, followed by M. avium (13.5%), M. gordonae (11.7%), M. kansasii (7.6%), and others.

Conclusion
The proportion of NTM among mycobacterial species detected in a tertiary hospital in Beijing, China, increased rapidly from year 2013 to 2018. Middle-aged patients are more likely to be infected with NTM, especially females. Mycobacterium intracellulare and Mycobacterium chelonae/ Mycobacterium abscessus were the most frequently detected NTM pathogens. Accurate and timely identification of NTM is important for diagnosis and treatment.

Abstract
Background
In recent years, the prevalence rate of acute coronary syndrome (ACS) in Chinese young women has been increasing significantly, becoming one of the main causes of death in young females. A matter of constant concern is what is the characteristics and differences in risk factors between young women with ACS and without ACS. This study aimed to investigate the characteristics and difference of risk factors in Chinese young women with ACS and to provide references for ACS prevention and treatment.

Methods
A 1:1 case-control study was conducted to evaluate risk factors of 415 young females with ACS (ACS group) who underwent PCI treatment and 415 young females without ACS (control group) who were hospitalized and confirmed by coronary angiography to exclude coronary heart disease from January 2010 to August 2016. The average age of the cases in groups was respectively (40.77 ± 4.02) and (40.57 ± 4.01) years-old (P > 0.05).

Results
The risk factors in ACS group were overweight (64.10%), hypertension (49.88%), hyperlipidemia (40.72%), diabetes (23.37%), depression or anxiety (16.63%), gynecological diseases (16.39%), Hyperuricemia (14.94%), family history of early-onset CHD (14.94%), hyperhomocysteinemia (11.33%), hypothyroidism (9.64%), hypercholesterolemia (8.43%) and high C-reactive protein (7.47%), and were significant difference (P < 0.01) compared with that of the control group. The average number of risk factors per case in ACS group was significantly more than that of control groups (P < 0.01). Regression analysis showed that hyperlipidemia, hyperhomocysteinemia, overweight (obesity), high CRP, hypertension, hypothyroidism, gynecological diseases, depression or anxiety, cardiac insufficiency, hypercholesterolemia, diabetes, oral contraceptives, family history of early-onset CHD, and autoimmune diseases were independent risk factors (P < 0.01). The bivariate correlation analysis between CRP level and age was r = − 0.158 (P < 0.01). The result showed the younger ACS patient is the higher serum CRP.

Conclusion
The independent risk factors of ACS in young women are hyperlipidemia, hyperhomocysteinemia, overweight, high CRP, hypertension, hypothyroidism, gynecological diseases, depression or anxiety, cardiac insufficiency, hypercholesterolemia, diabetes, oral contraceptives, family history of early-onset CHD, and autoimmune diseases. The co-existence of multiple risk factors is the main cause suffering from ACS in young women.
Efficacy of serum miRNA test as a non-invasive method to diagnose nonalcoholic steatohepatitis: a systematic review and meta-analysis

Published: June 2020

Abstract
Background
Nonalcoholic steatohepatitis (NASH) is a key turning point during the progression of nonalcoholic fatty liver disease (NAFLD). Recent studies have shown that serum miRNA tests may be effective in the diagnosis of NAFLD. We conducted a meta-analysis to assess the evidence for the diagnostic efficacy of serum miRNAs in patients with NAFLD and its subtype, NASH, in particular.

Methods
After a systematic review, sensitivity, specificity, and area under the receiver operating characteristics curve (AUROC) were pooled to determine the efficacy of serum miRNA test for the diagnosis of NAFLD and NASH. Clinical utility was evaluated by Fagan’s nomogram and likelihood ratio scattergram. Heterogeneity was evaluated by subgroup analysis and meta-regression. Publication bias was detected by Deeks’ funnel plot.

Results
We included 27 trials containing 1775 NAFLD patients (including simple steatosis and NASH) and 586 NASH patients. For NAFLD vs NASH, the pooled sensitivity, specificity, and AUROC were (0.71 vs. 0.74), (0.76 vs. 0.85) and (0.80 vs. 0.86), respectively. Serum miRNA had high accuracy for distinguishing NASH from simple steatosis, with an AUROC of 0.91. Among the most commonly studied serum miRNAs, miRNA-34a showed moderate diagnostic accuracy for NAFLD and the lowest heterogeneity (sensitivity I2 = 5.73%, specificity I2 = 33.16%, AUROC = 0.85). According to subgroup analysis and meta-regression, a lower BMI (< 30 kg/m2) might be a crucial source of heterogeneity.

Conclusions
As a novel non-invasive method, serum miRNA test exhibited robust diagnostic efficacy for NASH. Among these well-studied miRNAs, miRNA-34a was more available for diagnosis. Diagnosis of NAFLD by serum miRNA is more likely to be accurate in patients with BMI ≥ 30 kg/m2.
Effect of reduced formal care availability on formal/informal care patterns and caregiver health: a quasi-experimental study using the Japanese long-term care insurance reform

Published: June 2020

Abstract
Background
It is unclear how formal long-term care (LTC) availability affects formal /informal caregiving patterns and caregiver health. We tested the impact of reduced formal LTC availability on formal LTC service use, intensity of informal caregiving, and caregiver health.

Methods
Using a representative, repeated cross-sectional sample of Japanese caregivers providing care to co-resident family members from 2001 to 2016, we applied a difference-in-differences approach by observing caregivers before and after the major reform of the public Japanese LTC insurance (LTCI) in 2006. The reform reduced coverage benefits for non-institutionalized older persons with low care needs, but not for those with high care needs. We analyzed 12,764 caregivers aged ≥30 years (mean age 64.3 ± 11.8 years, 73.5% women) and measured indicators of formal LTC use, hours of informal caregiving, and caregiver self-reported health outcomes after propensity score matching to balance caregivers’ background characteristics.

Results
We found the 2006 LTCI reform relatively reduced the use of formal LTC services and relatively increased the percentage of experiencing long hours of informal caregiving (> 3 h per day) among the caregivers for seniors with low care needs compared to those for seniors with high care needs. The effects of the LTCI reform for the caregivers for seniors with low care needs were 2.2 percentage point higher on caregivers’ experiencing poor self-rated health (95% confidence interval [CI]: 0.7–3.7; p = 0.01), 2.7 percentage point higher on experiencing symptoms of a depressive state (95%CI: 0.5–4.8; p = 0.03), and 4.7 percentage point higher on experiencing symptoms of musculoskeletal diseases (95%CI, 3.6–5.7; p < 0.001), compared to those for seniors with high care needs.

Conclusions
Reduced formal care availability under the Japanese LTCI reform increased hours of informal caregiving corresponding to reduced use of formal LTC and deteriorated multiple dimensions of caregiver health. Our findings may highlight the importance of enhancing the availability of formal LTC services for caregiver health.

Abstract
Background
Falls are the leading cause of injuries among older adults. Perturbation-based balance training (PBT) is an innovative approach to fall prevention that aims to improve the reactive balance response following perturbations such as slipping and tripping. Many of these PBT studies have targeted reactive balance after slipping or tripping, despite both contributing to a large proportion of older adult falls. The goal of this randomized controlled trial was to evaluate the effects of PBT targeting slipping and tripping on laboratory-induced slips and trips. To build upon prior work, the present study included: 1) a control group; 2) separate training and assessment sessions; 3) PBT methods potentially more amenable for use outside the lab compared to methods employed elsewhere, and 4) individualized training for older adult participants.

Methods
Thirty-four community-dwelling, healthy older adults (61–75 years) were assigned to PBT or a control intervention using minimization. Using a parallel design, reactive balance (primary outcome) and fall incidence were assessed before and after four sessions of BRT or a control intervention involving general balance exercises. Assessments involved exposing participants to an unexpected laboratory-induced slip or trip. Reactive balance and fall incidence were compared between three mutually-exclusive groups: 1) baseline participants who experienced a slip (or trip) before either intervention, 2) post-control participants who experienced a slip (or trip) after the control intervention, and 3) post-PBT participants who experienced a slip (or trip) after PBT. Neither the participants nor investigators were blinded to group assignment.

Results
All 34 participants completed all four sessions of their assigned intervention, and all 34 participants were analyzed. Regarding slips, several measures of reactive balance were improved among post-PBT participants when compared to baseline participants or post-control participants, and fall incidence among post-PBT participants (18%) was lower than among baseline participants (80%). Regarding trips, neither reactive balance nor fall incidence differed between groups.

Conclusions
PBT targeting slipping and tripping improved reactive balance and fall incidence after laboratory-induced slips. Improvements were not observed after laboratory-induced trips. The disparity in efficacy between slips and trip may have resulted from differences in dosage and specificity between slip and trip training.
