Authors: Inoue Kazuho , Yamada Shohei , Hoshino Seiko , Watanabe Minoru , Kimura Kenjiro , Kamijo-Ikemori Atsuko 
Published: May 2022

Abstract
Background
This study aims to investigate the effect of the glucagon-like peptide-1 (GLP-1) receptor agonist (GLP-1RA) liraglutide on retinal pathological findings as compared with insulin and hydralazine using an animal model of type 2 diabetes with obesity, hypertension, and hyperlipidemia.

Methods
Male spontaneously diabetic Torii (SDT) fatty rats at 8 weeks of age were randomly assigned to three groups: the liraglutide group (SDT-lira, n = 6) received a subcutaneous injection of liraglutide from the age of 8 to 16 weeks, the SDT-ins-hyd group (n = 6) was provided both insulin against hyperglycemia and hydralazine against hypertension to match levels of both blood glucose and blood pressure to those of the liraglutide group, and the control group of SDT fatty rats (SDT-vehicle, n = 7) and a nondiabetic control group of Sprague–Dawley rats (SD, n = 7) were injected with vehicle only. Both eyeballs of all groups were collected at the age of 16 weeks.

Results
Retinal thickness, which was found in the SDT-vehicle group, was significantly prevented to similar levels in both the SDT-lira and SDT-ins-hyd groups. Immunohistological analysis revealed that GLP-1 receptor was not expressed in the retina of all rats. The ocular protein expression of monocyte chemoattractant protein-1, which causes a proinflammatory situation, was significantly upregulated in all SDT fatty rats as compared to SD rats, but the expression levels were similar between all SDT fatty rats. With regard to neovascularization in the eyes, there were no significant differences in protein expressions of vascular endothelial growth factor, CD31, or endothelial nitric oxide synthase in all rats.

Conclusions
The present study indicates that liraglutide prevents retinal thickening, dependent on blood glucose and blood pressure levels in SDT fatty rats without ocular neovascularization. However, the effects did not improve the ocular proinflammatory state.

Abstract
Background
Paediatric traumatic cataracts are an important but preventable cause of acquired blindness. Understanding the epidemiology of paediatric traumatic cataracts is a prerequisite for prevention. This study aimed to characterize the epidemiological profile of paediatric traumatic cataracts in southwest China.

Methods
The medical records of children (age range, 0–14 years old) who developed traumatic cataracts following open-globe injuries and were hospitalized at the Department of Ophthalmology at West China Hospital, between January 2011 and December 2020 were retrospectively analyzed. The demographic data, causes of injuries, posttraumatic complications, and visual acuity were recorded and analysed.

Results
A total of 716 eyes from 716 patients were analysed in this study, including 521 (72.8%) males and 195 females in a gender ratio of 2.67:1; 117 of the patients were of ethnic minorities. Paediatric traumatic cataracts occurred more frequently in winter (32.5%). Sharp metal objects (scissors/knives/needles/sheet metal/nails/darts) – induced ocular injuries accounted for the highest proportion, followed by botanical sticks (wooden sticks /bamboo sticks /bamboo skewers)-induced injuries, and then stationery items (pencils/pens/rulers/paper)-induced injuries. The majority (68.7%) of the patients were aged 2–8 years, and the peak range of age was 4 - 6 years. The injuries were a result of penetrating trauma in 64.9% of patients, and blunt force trauma in the remainder (35.1%). Additionally, 131 (18.3%) cases developed posttraumatic infectious endophthalmitis after injuries. Patients with eye injuries caused by needles (P < 0.001), wooden sticks (P = 0.016), and bamboo skewers (P = 0.002) were at a greater risk of developing infectious endophthalmitis. The most common identified foreign organism was Streptococcus, which accounted for 42% (21/50) of all culture-positive specimens and was sensitive to vancomycin. Among the children who were younger than 5 years, 44.4% (55/124) of those with traumatic cataracts presented a corrected distance visual acuity less than or equal to 0.1 after undergoing cataract surgery, but among the children who were older than 5 years, this proportion was significantly smaller, just 20.4% of children aged 6-10 years (P < 0.001) and 18.4% of children aged 11-14 years (P < 0.001).

Conclusion
The main causative agents of paediatric traumatic cataracts in southwest China were sharp metal objects, botanical sticks, and stationery items. Specific preventive measures are essential to reduce the incidence of paediatric traumatic cataract.

Published: May 2022

Abstract
Background
The COVID-19 pandemic led to improved hygiene and reduced social encounters. Near elimination of the activity of respiratory syncytial virus and influenza viruses were observed, worldwide. Therefore, we assessed the rates of pediatric outpatient clinic visits and medications prescribed at those visits during the coronavirus disease 2019 (COVID-19) pandemic and pre-COVID-19 period (2016–2019).

Methods
Monthly and annual incidence rates for respiratory and non-respiratory diagnoses and dispensed prescription rates were calculated. Acute gastroenteritis (AGE) visits were analyzed separately since the mode of transmission is influenced by hygiene and social distancing.

Results
Overall, 5,588,702 visits were recorded. Respiratory and AGE visits declined by 49.9% and 47.3% comparing the COVID-19 and pre-COVID-19 periods. The respective rate reductions for urinary tract infections, trauma, and skin and soft tissue infections were 18.2%, 19.9%, and 21.8%. Epilepsy visits increased by 8.2%. Overall visits rates declined by 21.6%. Dispensed prescription rates of antibiotics and non-antibiotics respiratory medications declined by 49.3% and 44.4%, respectively. The respective declines for non-respiratory antibiotics and non-antibiotics were 15.1% and 0.2%. Clinic visits and prescription rates reductions were highest in April–May, following the first lockdown in Israel.

Conclusions
COVID-19 pandemic resulted in a substantial reduction in respiratory outpatient clinic visits and dispensed respiratory drugs, with only a mild reduction seen for non-respiratory visits. These trends were probably driven by COVID-19 mitigation measures and by the profound disruption to non-SARS COV-2 respiratory virus activity.
The predictive performance of surgical treatment in upper molars with combined bony defect and furcation involvement: a retrospective cohort study
Authors: Chiu Meng-Yao , Lin Cho-Ying , Kuo Pe-Yi 
Published: May 2022

AbstractBackgroundTo evaluate the impact of combined defects, bony destruction and furcation involvement, on disease resolution after surgery in terms of pocket elimination, absence of inflammation, furcation improvement and predictive performance.MethodsCombined bony (intrabony (+) or (−)) and furcation defects (FI degree 1 or 2) at maxillary molars in patients diagnosed as periodontitis stage III to IV, being through periodontal surgery and at least 6 months follow-up were retrospectively screened. Cumulative predictability (CR, %), failure of treatment and the change of clinical parameters from baseline at pre-operative visit to the latest maintenance care, including pocket depth (PD), horizontal and vertical furcation involvement (FI) were analyzed. Failure of treatment with low predictability was defined as residual PD > 4 mm with bleeding on probing during maintenance period.ResultsThirty-three patients with fifty-one combined defects were included. Statistical analysis showed significant overall PD reduction and FI improvement (p < 0.001). Combined FI degree 2 with intrabony (+) defects revealed more horizontal furcation improvement compared with FI degree 2 with suprabony defect (p = 0.007). However, type of combined defects was not relevant to CR (p = 0.702) and PD reduction (p = 0.707). Among all parameters, baseline PD with proximal FI degree 2 was indicated to failure of treatment.ConclusionsDifferent types of combined defects, deep baseline pocket and proximal FI degree 2 would compromise the predictability of treatment outcomes in upper molars. Nevertheless, the combination of surgical treatment and strict maintenance care could still yield high predictability and survival rate.Trial registration: retrospectively registered.
Antimicrobial effects and mechanical properties of poly(methyl methacrylate) as an orthodontic acrylic resin containing Curcumin-Nisin-poly(l-lactic acid) nanoparticle: an in vitro study
Authors: Pourhajibagher Maryam , Noroozian Mohammad , Ahmad Akhoundi Mohammad Sadegh , Bahador Abbas 
Published: May 2022

Abstract
Background
The porous surface of acrylic orthodontic removable appliances creates a niche for microbial plaque accumulation, and changes the oral flora by raising cariogenic bacteria including Streptococcus mutans. In this study, we evaluated the mechanical properties and antimicrobial activities of incorporating different concentrations of Curcumin-Nisin-poly(l-lactic acid) nanoparticle (CurNisNps) into orthodontic acrylic resin against Streptococcus mutans and Candida albicans.

Methods
Following synthesis and characterization of CurNisNps, acrylic resin specimens with different concentrations of CurNisNps (0, 1, 2, 5, and 10% w/w) were fabricated. Flexural strength values, antimicrobial effects, anti-biofilm potential, and anti-metabolic activity against S. mutans and C. albicans were assessed at different time intervals. Also, the expression of the virulence-factor-related genes of S. mutans and C. albicans was assessed by quantitative real-time polymerase chain reaction following treatment with CurNisNps.

Results
Acrylic resin containing 10% CurNisNps (30.76 ± 3.91 MPa) showed flexural failure in comparison with acrylic resin specimens without CurNisNps (50.67 ± 1.82 MPa) as the control group (P < 0.05). There was no significant decrease in the flexural strength values in samples containing 1, 2, and 5% of CurNisNps in comparison to the control group (P > 0.05). Acrylic resin with 5% CurNisNps showed the highest concentration of CurNisNps and clinically accepted flexural strength value (14.89 ± 3.26 MPa, P < 0.05) simultaneously. In the disc agar diffusion assay, 5% CurNisNps showed a high level of inhibitory activity for the test microorganisms. The reduction of growth inhibition zones of the different concentrations of CurNisNps against test microorganisms was positively associated with the time, in such a way that it was reduced significantly after 60 days. The anti-biofilm and anti-metabolic activities of acrylic resin specimens containing a 5% concentration of CurNisNps against S. mutans and C. albicans could significantly decrease the expression levels of gtfB (6.8-fold) and HWP (3.4-fold) in S. mutans and C. albicans, respectively.

Conclusions
Our data support that 5% (w/w) of CurNisNps can serve as an excellent orthodontic acrylic resin additive against S. mutans and C. albicans biofilm without adverse effects on its mechanical property.

Authors: Choi Sun-Gyu , Lee Eun-Young , Lee Ok-Jun , Kim Somi , Kang Ji-Yeon , Lim Jae Seok 
Published: May 2022

Abstract
Background
This study aimed to develop and validate five machine learning models designed to predict actinomycotic osteomyelitis of the jaw. Furthermore, this study determined the relative importance of the predictive variables for actinomycotic osteomyelitis of the jaw, which are crucial for clinical decision-making.

Methods
A total of 222 patients with osteomyelitis of the jaw were analyzed, and Actinomyces were identified in 70 cases (31.5%). Logistic regression, random forest, support vector machine, artificial neural network, and extreme gradient boosting machine learning methods were used to train the models. The models were subsequently validated using testing datasets. These models were compared with each other and also with single predictors, such as age, using area under the receiver operating characteristic (ROC) curve (AUC).

Results
The AUC of the machine learning models ranged from 0.81 to 0.88. The performance of the machine learning models, such as random forest, support vector machine and extreme gradient boosting was significantly superior to that of single predictors. Presumed causes, antiresorptive agents, age, malignancy, hypertension, and rheumatoid arthritis were the six features that were identified as relevant predictors.

Conclusions
This prediction model would improve the overall patient care by enhancing prognosis counseling and informing treatment decisions for high-risk groups of actinomycotic osteomyelitis of the jaw.
Long non-coding RNA TFAP2A-AS1 plays an important role in oral squamous cell carcinoma: research includes bioinformatics analysis and experiments
Authors: Jie Guo , Peng ShiXiong , Cui ZiFeng , He Chen , Feng XuPo , yang Kaicheng 
Published: May 2022

Abstract
Background
Oral squamous cell carcinoma (OSCC) is the most common neck and head malignancies, and the prognosis is not good. Studies shown that the long non-coding RNA (lncRNA) TFAP2A-AS1 is involved in the progression of multiple cancers. However, the role of lncRNA TFAP2A-AS1 in OSCC remains unclear. We aimed to explore the functions and expression in OSCC.

Methods
The lncRNA profiles for OSCC patients were acquired from the TCGA. Based on these data, the data mining of TFAP2A-AS1 in patients with OSCC were performed. The functions of TFAP2A-AS1 were determined by bioinformatics analysis. The expression and roles in cell growth were tested by RT-qPCR and MTS assay. Cell invasion and migration were tested by wound healing and transwell assays.

Results
The consequences displayed that TFAP2A-AS1 was upregulated in the TCGA datasets. The expression of TFAP2A-AS1 was higher in OSCC samples. Bioinformatics analysis shown that TFAP2A-AS1 might be associated with the P53 signaling pathway. Cell culture experiments indicated that deficiency of TFAP2A-AS1 inhibited cell growth, invasion, and migration, and overexpression of it could opposite results in SCC-25 cells.

Conclusion
The results suggested that TFAP2A-AS1 was overexpressed in OSCC cells, which could facilitate OSCC cell proliferation, migration, and invasion.
A cumulative prospect theory-based method for group medical emergency decision-making with interval uncertainty
Authors: Sun Jiayi , Zhou Xiang , Zhang Juan , Xiang Kemei , Zhang Xiaoxiong , Li Ling 
Published: May 2022

Abstract
Background
An emergency response to a medical situation is generally considered to be a risk decision-making problem. When an emergency event occurs, it makes sense to take into account more than one decision maker’s opinions and psychological behaviors. The existing research tends to ignore these multidimensional aspects. To fill this literature gap, we propose a multi-attribute model.

Methods
The model is based on cumulative prospect theory (CPT), considering multiple experts’ psychological factors. By not assuming full rationality, we extend existing models to allow multiple experts’ risk preferences to be incorporated into the decision-making process in the case of an emergency. Then, traditional CPT is extended by allowing for multiple attributes. In addition, rather than using crisp data, interval values are adopted to tackle the usual uncertainties in reality.

Results
The multi-attribute CPT based model proposed can deal with the selection of potential emergency alternatives. The model incorporates interval values to allow more uncertainty and the comparative studies show that the optimal solution changes under different scenarios.

Conclusions
Our illustrative example and comparative study show that considering multiple experts and multiple attributes is more reasonable, especially in complicated situations under an emergency. In addition, decision-makers’ risk preferences highly affect the selection outcomes, highlighting their importance in the medical decision-making process. Our proposed model can be applied to similar fields with appropriate modifications.

Published: May 2022

Abstract
Background
Iran’s nursing education has undergone significant modifications in the last decades, especially following the Islamic revolution and the Iran-Iraq war. This review outlined changing trends in Iran’s nursing education and evaluate its status compared to other developing and developed countries.

Methods
Six international and two national electronic data sources were searched up to May 2021, using relevant keywords and terms. The studies were included if they addressed history, development, or evolutionary aspects of Iran’s nursing education or evaluated its status by comparing it with developing or developed countries, using Bereday's model. To obtain more relevant information, the organizational documents of the Iranian Ministry of Health and Medical Education and the Iranian Ministry of Culture and Higher Education were searched. Of 753 evidence found in the initial search, 73 were considered eligible for this review. A systematic and unbiased data synthesis was performed and a narrative and tabulated summary was presented.

Results
The evolution in Iran’s nursing education has resulted in the establishment of Bachelor, Master, and Ph.D. programs. Iran’s nursing education system plays an important role in fulfilling the healthcare system’s mission, and it does not hold a dissatisfactory position in comparison with other developed and developing countries. However, this system is expected to be more versatile for the upcoming changes and advancements.

Conclusion
Iran’s nursing education has a moderate rating despite recent changes. Hence, this system has to be modified in some aspects by adopting experiences of other countries, with an appropriate and successful education system, to prepare future highly competent nurses.

Published: May 2022

Abstract
Background
Adenoid cystic carcinoma (ACC) is one of the most common malignant salivary gland tumors. Moreover, the unique biological characteristics and complex structures of ACC contribute to its poor survival rates. Recently, proteasome inhibitors have been shown to elicit satisfactory therapeutic effects in the treatment of certain solid tumors, but few studies have been implemented to investigate the effects of proteasome inhibitor therapy for ACC.

Methods
In this present study, cell counting kit-8 assay and flow cytometry assay were performed to examine the effects of proteasome inhibitor (MG132) on cell viability and apoptosis. We applied western blot and immunofluorescence staining to explore the expression of the Nrf2/Keap1 signaling pathway and P62, additionally Nrf2 inhibitor (ML385) was utilized to evaluate the role of Nrf2/Keap1 signaling pathway in MG132-induced cell apoptosis.

Results
Our data indicated that MG132 significantly suppressed the growth of ACC-83 cells(MG132 10µM P = 0.0046; 40µM P = 0.0033; 70µM P = 0.0007 versus control) and induced apoptosis (MG132 10µM P = 0.0458; 40µM P = 0.0018; 70µM P = 0.0087 versus control). The application of MG132 induced the up-regulation of Nrf2/Keap1 signaling pathway. Furthermore, inhibition of Nrf2 attenuated the therapeutic effects of MG132 for ACC (both ML385 + MG132 10µM P = 0.0013; 40µM P = 0.0057; 70µM P = 0.0003 versus MG132). P < 0.05 was considered statistically significant.

Conclusions
Our results revealed that proteasome inhibitors MG132 could inhibit the cell viability and induce the apoptosis of ACC through Nrf2/Keap1 signaling pathway.

AbstractBackgroundSome academic organizations recommended that physicians intubate patients with COVID-19 with a relatively lower threshold of oxygen usage particularly in the early phase of pandemic. We aimed to elucidate whether early intubation is associated with decreased in-hospital mortality among patients with novel coronavirus disease 2019 (COVID-19) who required intubation.MethodsA multicenter, retrospective, observational study was conducted at 66 hospitals in Japan where patients with moderate-to-severe COVID-19 were treated between January and September 2020. Patients who were diagnosed as COVID-19 with a positive reverse-transcription polymerase chain reaction test and intubated during admission were included. Early intubation was defined as intubation conducted in the setting of ≤ 6 L/min of oxygen usage. In-hospital mortality was compared between patients with early and non-early intubation. Inverse probability weighting analyses with propensity scores were performed to adjust patient demographics, comorbidities, hemodynamic status on admission and time at intubation, medications before intubation, severity of COVID-19, and institution characteristics. Subgroup analyses were conducted on the basis of age, severity of hypoxemia at intubation, and days from admission to intubation.ResultsAmong 412 patients eligible for the study, 110 underwent early intubation. In-hospital mortality was lower in patients with early intubation than those with non-early intubation (18 [16.4%] vs. 88 [29.1%]; odds ratio, 0.48 [95% confidence interval 0.27–0.84];p = 0.009, and adjusted odds ratio, 0.28 [95% confidence interval 0.19–0.42];p < 0.001). The beneficial effects of early intubation were observed regardless of age and severity of hypoxemia at time of intubation; however, early intubation was associated with lower in-hospital mortality only among patients who were intubated later than 2 days after admission.ConclusionsEarly intubation in the setting of ≤ 6 L/min of oxygen usage was associated with decreased in-hospital mortality among patients with COVID-19 who required intubation.Trial RegistrationNone.
