Abstract
​ Background: Ganoderma sp., such as Ganoderma tsugae (GT), play an important role in traditional Chinese medicine. Ganoderma sp. contains several constituents, including Sacacchin, which has recently drawn attention because it can not only enhance the repair of muscle damagebut also strengthen themuscle enforcement. Although Ganoderma sp. have a therapeutic effect for neuromuscular disorders, the underlying mechanism remains unclear. This study investigated the effect and underlying molecular mechanism of micronized sacchachitin(mSC) on satellite cells (SCs), which are known as the muscle stem cells. Methods: The myogenic cells, included SCs (Pax7 +) were isolated from tibialis anterior muscles of a healthy rat and were cultured in growth media with different mSC concentrations. For the evaluation of SC proliferation, these cultivated cells were immunostained with Pax7 and bromodeoxyuridineassessed simultaneously. The molecular signal pathway was further investigated by using Western blotting and signal pathway inhibitors. Results: Our results revealed that 200 µg/mL mSC had an optimal capability to significantly enhance the SC proliferation. Furthermore, this enhancement of SC proliferation was verified to be involved with activation of TAK1-JNK-AP-1 signaling pathway through TLR2, whose expression on SC surface was confirmed for the first time here. Conclusion: Micronized sacchachitinextracted fromGT was capable of promoting the proliferation of SC under a correct concentration.

Abstract
Background: High-intensity statin therapy is typically used in patients with acute myocardial infarction (AMI) for secondary prevention. However, there have been consistent concerns regarding its association with diabetes mellitus. We investigated the effect of high-intensity atorvastatin and rosuvastatin on new-onset diabetes mellitus (NODM) and cardiovascular outcomes over a 3-year follow-up period.Methods: Data from the Korea Acute Myocardial Infarction Registry were collected from November 2011 to October 2015, and 13,104 patients with AMI were enrolled from major cardiovascular centers. Among them, 2,221 patients without diabetes who had been administered with high-intensity atorvastatin (40–80 mg) and rosuvastatin (20 mg) were investigated. The atorvastatin and rosuvastatin groups were evaluated for the incidence of NODM and major adverse cardiac events (MACE) including death, myocardial infarction, and revascularization cases in the following 3 years.Results: Baseline characteristics were comparable between the two groups. Event-free survival rate of NODM and MACE was not significantly different between the atorvastatin and rosuvastatin groups (92.5% vs. 90.8%, respectively; Log-rank P-value = 0.550). The event-free survival rate of MACE was also not significantly different between atorvastatin and rosuvastatin groups (89.0% vs. 89.6%, respectively; Log rank P-value = 0.662). Multivariate Cox analysis revealed that statin type was not a prognostic factor in the development of NODM and MACE.Conclusions: Administering high-intensity atorvastatin and rosuvastatin in patients with AMI produced comparable effects on NODM and clinical outcomes, suggesting their clinical equivalence in secondary prevention.

Abstract
Background: Hospitalizations carry considerable risks for frail, elderly patients; this is especially true for patients with dementia, who are more likely to experience delirium, falls, functional decline, iatrogenic complications, and infections when compared to their peers without dementia. Since up to two thirds of patients in long-term care (LTC) facilities have dementia, there is interest in identifying factors associated with transitions from LTC facilities to hospitals. The purpose of this study was to investigate the association between dementia status and incidence of hospitalization among residents in LTC facilities in Ontario, Canada, and to determine whether this association is modified by linguistic factors. Methods: We used linked administrative databases to establish a prevalent cohort of 81,188 residents in 628 LTC facilities from April 1st 2014 to March 31, 2017. Diagnoses of dementia were identified with a previously validated algorithm; all other patient characteristics were obtained from in-person assessments. Residents’ primary language was coded as English or French; facility language (English or French) was determined using language designation status according to the French Language Services Act. We identified all hospitalizations within 3 months of the first assessment performed after April 1st 2014. We performed multivariate logistic regression analyses to determine the impact of dementia and resident language on the incidence of hospitalization; we also considered interactions between dementia and both resident language and resident-facility language discordance. Results: The odds of hospitalization were 39% lower for residents with dementia compared to residents without dementia (OR 0.61, 95% CI 0.57–0.65). Francophones had lower odds of hospitalization than Anglophones, but this difference was not statistically significant (OR 0.91, 95% CI 0.81 – 1.03). However, Francophones without dementia were significantly less likely to be hospitalized compared to Anglophones without dementia (OR 0.71, 95% CI 0.53 – 0.94). Resident-facility language discordance did not significantly affect hospitalizations. Conclusions: Residents in LTC facilities were generally less likely to be hospitalized if they had dementia, or if their primary language was French and they did not have dementia. These findings could be explained by differences in end-of-life care goals; however, they could also be the result of poor patient-provider communication.

Abstract
Background

Several studies compared everolimus-eluting bioresorbable scaffolds (EE-BRS) with everolimus-eluting stents (EES), but only few assessed these devices in patients with diabetes mellitus.

Aim

To evaluate the safety and efficacy outcomes of all-comer patients with diabetes up to 2 years after treatment with EE-BRS or EES.

Methods

We performed a post-hoc pooled analysis of patient-level data in diabetic patients who were treated with EE-BRS or EES in 3 prospective clinical trials: The ABSORB DM Benelux Study (NTR5447), TWENTE (NTR1256/NCT01066650) and DUTCH PEERS (NTR2413/NCT01331707). Primary endpoint of the analysis was target lesion failure (TLF): a composite of cardiac death, target vessel myocardial infarction or clinically driven target lesion revascularization. Secondary endpoints included major adverse cardiac events (MACE): a composite of all-cause death, any myocardial infarction or clinically driven target vessel revascularization, as well as definite or probable device thrombosis (ST).

Results

A total of 499 diabetic patients were assessed, of whom 150 received EE-BRS and 249 received EES. Total available follow-up was 222.6 patient years (PY) in EE-BRS and 464.9 PY in EES. The adverse events rates were similar in both treatment groups for TLF (7.2 vs. 5.2 events per 100 PY, p=0.39; adjusted hazard ratio (HR)=1.48 (95% confidence interval (CI): 0.77-2.87), p=0.24), MACE (9.1 vs. 8.3 per 100 PY, p=0.83; adjusted HR=1.23 (95% CI: 0.70-2.17), p=0.47), and ST (0.9 vs. 0.6 per 100 PY, p>0.99).

Conclusion

In this patient-level pooled analysis of patients with diabetes mellitus from 3 clinical trials, EE-BRS showed clinical outcomes that were quite similar to EES.

Published: September 2020

Abstract
Background: To date, the rates of potentially life-threatening condition (PTLC), maternal near miss (MNM) and maternal deaths in pregnant patients with type 1 diabetes mellitus (T1DM) and variables associated to it have not been studied. Methods: This study was as a cross-sectional retrospective study conducted at São Paulo Hospital of Universidade Federal de São Paulo, a tertiary hospital that provides public medical care through the Brazilian unified health system to high-risk pregnancies. Inclusion criteria were T1DM pregnant women who delivered from January 2005 to December 2015. Three groups were established by the World Heath Organization criteria and associations were assessed using the chi-square test in between MNM and no morbidity or PLTC and no morbidity. A P value < 0.05 was considered statistically significant. Results: The final sample included 137 patients, 8 MNM cases (5.84%), 51 PLTC (37.23%), no cases of maternal deaths and 78 patients (56.93%) did not present any complication. Moreover, there were 122 live births, resulting in a near miss rate of 65.5 per 1.000 live births in patients with T1DM. Two of the MNM cases were for clinical criteria (uncontrollable fit in both) and laboratory criteria for the other six: one patient with severe acute azotemia (creatinine >300 μmol/ml), one patient with severe hypoperfusion (lactate >5 mmol/L) and four of them with loss of consciousness and the presence of glucose and ketoacids in urine. PLTC criteria were studied in MNM and PLTC cases. Prolonged hospital stay was the most prevalent PLTC criteria in both groups (100% of MNM cases and 96% of PLTC), followed by renal failure in 50% of MNM cases and severe preeclampsia in 22% of PLTC cases. This study could not find any association between prenatal factors or sociodemographic characteristics with maternal morbidity. Conclusions: MNM rate in T1DM was extremely high, and determined by complications of the primary disease or hypertensive disorders. No sociodemographic variables studied were related to maternal morbidity; therefore, we could not predict what increases MNM and PLTC in this specific population.

Published: September 2020

Abstract
Polylactic acid (PLA) is a thermoplastic and biodegradable polyester, largely derived from renewable resources such as corn starch, cassava starch and sugarcane. However, PLA is only soluble in a narrow range of solvents such as tetrahydrofuran, dioxane, chlorinated solvents and heated benzene. The limited choices of solvent for PLA dissolution have imposed singificant challenges in the development of specifically engineered PLA nanofibers with electrospinning techniques. Generally, the electrospun polymeric materials have been rendered with unique properties such as high porosity and complex geometry while maintaining its biodegradability and biocompatibility for emerging biomedical applications. In this study, a new anticancer drug delivery system composed of PLA nanofibers with encapsulated paclitaxel was developed by the electrospinning of the respective nanofibers on top of a spin-coated thin film with the same chemical compositions. Our unique approach is meant for promoting strong bonding between PLA-based nanofibers and their respective films in order to improve the prolonged release properties and composite film stability within a fluctuative phyiochemical environment during cell culture. PLA/paclitaxel nanofiber supported on respective polymeric films were probed by scanning electronic microscope, Fourier transform infrared spectrometer and water contact measurement for determining their surface morphologies, fibers’ diameters, molecular vibrational modes, and wettability, respectively. Moreover, PLA/paclitaxel nanofibers supported on respective spin-coated films at different loadings of paclitaxel were evaluated for their abilities in killing human colorectal carcinoma cells (HCT-116). More importantly, MTT assays showed that regardless of the concentrations of paclitaxel, the growth of HCT-116 was effectively inhibited by the prolonged release of paclitaxel from PLA/paclitaxel nanofibers. An effective prolonged delivery system of paclitaxel based on PLA nanofiber-based film has demonstrated exciting potentials for emerging applications as implantable drug delivery patch in post-surgical cancer eradication.

Abstract
The Drosophila melanogaster Germ cell-expressed protein (GCE) is a paralog of the juvenile hormone (JH) receptor - Methoprene tolerant protein (MET). Both proteins mediate JH function, preventing precocious differentiation during D. melanogaster development. Despite that GCE and MET are often referred to as equivalent JH receptors, their functions are not fully redundant and show tissue specificity. Both proteins belong to the family of bHLH-PAS transcription factors. The similarity of their primary structure is limited to defined bHLH and PAS domains, while their long C-terminal fragments (GCEC, METC) show significant differences and are expected to determine differences in GCE and MET protein activities. In this paper we present the structural characterization of GCEC as a coil-like intrinsically disordered protein (IDP) with highly elongated and asymmetric conformation. In comparison to previously characterized METC, GCEC is less compacted, contains more molecular recognition elements (MoREs) and exhibits a higher propensity for induced folding. The NMR shifts perturbation experiment and pull-down assay clearly demonstrated that the GCEC fragment is sufficient to form an interaction interface with the ligand binding domain (LBD) of the nuclear receptor Fushi Tarazu factor-1 (FTZ-F1). Significantly, these interactions can force GCEC to adopt more fixed structure that can modulate the activity, structure and functions of the full-length receptor. The discussed relation of protein functionality with the structural data of inherently disordered GCEC fragment is a novel look at this protein and contributes to a better understanding of the molecular basis of the functions of the C-terminal fragments of the bHLH-PAS family.

Published: September 2020

Abstract
Background: Intimate partner violence (IPV) against women and poor nutritional status are growing health problems in low and middle-income countries (LMICs). Moreover, violence against women has been shown to be associated with poor nutrition. This study investigated the relationship between IPV and nutritional status (i.e., underweight, overweight, and obesity) among women of reproductive age (15-49 years) in Zimbabwe. Methods: Pooled data from the 2005/2006, 2010/2011, and 2015 Zimbabwe Demographic Health Surveys (ZDHS) on 13,008 married/cohabiting women were analysed. Multinomial logistic regression models were used to examine the associations between the various forms of IPV and the nutritional status of women. We further estimated the prevalence of BMI ≥ 25.0 kg/m2 (overweight and obesity) by intimate partner violence type.Results: The mean BMI of women was 24.3 kg/m2, more than one-fifth (24%) were overweight and about 12% were obese. Forty-three percent (43%) of women reported to have ever experienced at least one form of intimate partner violence. More than one-third (35%) of women who reported to have ever experienced at least one form of intimate partner violence had a BMI ≥ 25.0 kg/m2 (p< 0.01). Relative to normal weight, women who had ever experienced at least one form of IPV (i.e., physical, emotional, or sexual) were more likely to be obese (aOR = 2.59; 95% CI = 1.05–6.39). Women’s exposure to any form of intimate partner violence was not significantly associated with the likelihood of being underweight or overweight relative to normal weight.Conclusions: The study findings showed that women of reproductive age in Zimbabwe are at high risk of both IPV and excess weight. Moreover, we found a positive relationship between IPV and obesity. Public health interventions that target the well-being, empowerment, and development of women are needed to address the complex issue of IPV and adverse health outcomes, including obesity.

Abstract
Background Loss to follow-up (LFTU) among HIV patients continues to be a major obstacle to achieving treatment goals with the risk of failure to achieve viral suppression and thereby increased HIV transmission. Although use of clinical decision support systems (CDSSs) has been shown to improve adherence to HIV clinical guidance, this is the first study ever conducted to show its effect on LTFU in low-resource settings. Methods We analyzed data from a cluster-randomized trial conducted at 20 HIV clinics in western Kenya to assess the effects of a CDSS implemented as alerts on an electronic health records (EHR) system on: (1) the proportion of patients that were LTFU, (2) LTFU patients traced and successfully referred back to treatment, and (3) the time from enrollment on treatment to LTFU. Results Among eligible 5,901 patients receiving ART, 40.6% (n=2,396) were LTFU at any time during the study period. Lack of a CDSS was associated with higher LTFU among the ART patients (Adjusted Odds Ratio - aOR=1.45, 95% CI: 1.35-1.55). The proportions of patients linked back to treatment were 29.1% (95% CI: 27.6– 0.6) and 34.1 % (95% CI: 32.1–36.2) in EHR only and EHR with CDSS sites respectively. There was no statistically significant association between the use of a CDSS and time to LTFU.Conclusion A CDSS can potentially improve quality of care through reduction of LTFU among HIV patients in a resource-limited country. CDSS is only part of the solution to LTFU and would be most effective if implemented together with other interventions.
Factors Hindering the Effective Application of User Knowledge in the Designing of New Home Healthcare Devices: Investigating Thirty-Eight Devices and Their Manufacturers
Authors: Yang Fan , Mahmud Abdullah Al 
Published: September 2020

Abstract
Background: This study explored the factors hindering the effective application of user knowledge in the designing of new Home Healthcare Device (HHCD), along with the interrelationships between the factors. The demand for HHCDs arises, however many HHCDs on the market are not designed to reflect the needs and features of the end-users. Methods: We first analysed the project documents of thirty-eight carefully selected HHCDs produced by five manufacturers. Then we interviewed in a total of thirty stakeholders who were involved in the development of these devices.Results: The use of insufficient user insights in HHCD development were mainly attributed to the four factors: (i) the user insights utilised in formulating project strategies and the designing of new devices; (ii) the sources of user information; (iii) the execution of user research; and (iv) the formulation of the manufacturers’ principal NPD processes.Conclusions: The users’ characteristics and needs were not sufficiently reflected within the device development processes, as the manufactures were in short of commitment and motivation in deploying formal user research. One root cause was that most of the projects were initiated following the requests from the public sector (the clients). In contrast, the end-users were perceived by the manufacturers as having little impact on the success of the devices. Actual or potential applications of this study include the facilitation of the appropriate application of human factors methods in the development of new HHCDs, and the improvement of the user performance of the end-devices.

Abstract
Objectives: Metallo-beta-lactamases play a major role in the resistance of Pseudomonas aeruginosa to carbapenems. The aim of this study was the phenotypic and molecular detection of IMP and SPM carbapenemase genes in 100 carbapenem-resistant clinical isolates of P. aeruginosa. The isolates identified using standard microbiological tests, and their antibiotic susceptibility pattern determined by disk agar diffusion (Kirby Bauer) method. Phenotypic identification of Metallo-beta-lactamase-producing strains assessed by the combined disk test (CDT). Then, PCR was used to detect the presence of IMP and SPM genes.Results: The highest and lowest levels of antibiotic resistance were observed against gentamicin (40%) and piperacillin-tazobactam (13%), respectively. Besides, 40 isolates (40%) had the Multi-drug Resistant (MDR) phenotype, while 5 (12.5%) MDR isolates were resistant to all antibiotics tested. The results of the CDT showed that among 43 carbapenem non-susceptible clinical isolates of P. aeruginosa, 33 (76.74%) isolates were Metallo-beta-lactamase-producing strains. Also, the frequency of the IMP gene was determined to be 9%, while none of these isolates carried the SPM gene. Due to the high prevalence of carbapenem-resistant and MDR P. aeruginosa in this study, routine antibiotic susceptibility testing and phenotypic identification of carbapenemase production by this bacterium are necessary for proper selection of antibiotics.
