Published: April 2022

Abstract
Background
In neonatal patients with necrotizing enterocolitis (NEC) the inflammatory response is mediated by a plurality of different proteins. The proteins olfactomedin 4 (OLFM4) and lysozyme (LYZ) are part of the intestinal mucosal defense and especially OLFM4 has rarely been evaluated in neonatal gastrointestinal diseases. The aim of this study was to analyze whether expression levels of both proteins of innate immunity, OLFM4 and lysozyme, were increased during NEC in neonates.

Methods
Intestinal tissues of patients with NEC were examined with immunohistochemical staining of formalin-fixed and paraffin-embedded sections of resected tissue using antibodies against OLFM4 and lysozyme. Staining-positive tissues were semi-quantitatively scored from 0 (no staining), 1 (weak staining), 2 (moderate staining) to 3 (highly intense staining) by two individual investigators. Intestinal tissue of infants with volvulus was used as a control as other intestinal tissue without major inflammation was not available.

Results
Both applied antibodies against OLFM4 showed different staining patterns with higher staining intensity of the antibody OLFM4 (D1E4M). OLFM4 (median score of the antibody OLFM4 (D1E4M): 3.0) and lysozyme (median score: 3.0) are highly expressed in intestinal and immune cells during NEC. Expression of OLFM4 and lysozyme in the control samples with volvulus was observable but significantly lower (median score of the antibody OLFM4 (D1E4M): 1.25; median score of the antibody against LYZ: 2.0; p = 0.033 and p = 0.037, respectively).

Conclusions
Both proteins, OLFM4 and lysozyme, may play a role in the pathogenesis of NEC in neonatal patients, but the exact mechanisms of OLFM4 and lysozyme function and their role in immunological responses have not yet been resolved in detail. These observations add new insights as basis for further large-scale population research.

Abstract
Background
Behaviour change communication is a proven health communication strategy among used in promoting changes in knowledge, attitudes, beliefs, and behaviours’, especially for communicable diseases. Few studies have been conducted on its effectiveness for non-communicable diseases prevention and control. This study was conducted as an evaluation assessment for a non-communicable disease focused intervention implemented in Imo and Kaduna States, Nigeria.

Methods
A twelve-month long strategic behaviour change communication intervention on hypertension and diabetes was implemented in selected communities across Imo and Kaduna States, Nigeria. This study adopted a quasi-experimental design approach among adult residents aged at least 35 years to assess the effectiveness of the intervention. Data was collected at baseline (prior to implementation of the interventions) and at the endline; among study and control groups. A uniform study tool was used to collect information on awareness & lifestyle related factors for Hypertension & Diabetes.

Results
The awareness of hypertension was 98.9% among the respondents in the study group compared to 94.4% among the baseline respondents (χ2 = 20.276, p < 0.001). The history of blood pressure check was recorded among 86.8% of the study group compared to 79.0% of the baseline group (χ2 = 20.27, p < 0.001). In the last 6 months prior to the study, 71.9% of the study group compared to 30.6% of the baseline group (χ2 = 243.34, p = 0.002) had blood glucose check at least once. Daily alcohol consumers make up 36.8% of the baseline respondents, compared to 22.6% in the study group (χ2 = 33.84, p < 0.001) and 30.6% of those in the control group compared to the 22.6% of the study group (χ2 = 9.23, p = 0.002). The mean (± SD) knowledge score on hypertension and diabetes was 18.12 (± 8.36) among the study group compared to 11.84 (± 6.90) among the baseline group (t = 15.29, p < 0.001), and compared to 10.97 (± 8.79) among the control group (t = 13.08, p < 0.001).

Conclusion
Significant changes in lifestyle practices, knowledge of hypertension and diabetes and risk perception was observed following the implementation of community-based behaviour change communication interventions. There is a need to increased access to health education and promotion interventions for non-communicable diseases.

Published: April 2022

AbstractBackgroundBased on an increased prevalence of diabetes, asthma and hypertension among women in reproductive age, understanding the risk factors of non-communicable diseases (NCDs) is crucial to inform policy and program interventions to address the problem. In this study, we empirically assessed the associations of behavioural factors such as alcohol consumption and tobacco use and a variety of socioeconomic characteristics with prevalence of NCDs in adult women.MethodsThe data were derived from the National Family Health Survey conducted in 2015–16. The effective sample size for the present paper was 699,686 women aged 15–49 years in India. Descriptive statistics along with bivariate analysis were conducted to find the preliminary results. Additionally, multivariable logistic regression analysis was conducted to find the relationship between NCDs and behavioural factors such as alcohol consumption and tobacco use. Moreover, population attributable risk was estimated in the present study.ResultsIt was revealed that 15.9% of women had any of the NCDs. A proportion of 0.8% of women smoked tobacco whereas 5.5% of women consumed smokeless tobacco. Also, a proportion of 1.2% of women consumed alcohol in the current study. The odds of having NCDs among women who smoked tobacco, consumed smokeless tobacco and consume alcohol were 16, 8 and 20% significantly higher than the odds of having NCDs among women who did not smoke tobacco, consume smokeless tobacco and consume alcohol respectively. The population attributable risk of having NCDs was 1.8% (p < 0.001) for women who smoked, 0.8% (p < 0.001) for women who consumed smokeless tobacco and 2.2% (p < 0.001) for women who consumed alcohol. Besides, the odds of having NCDs among overweight and obese women were 2.25 and 3.60 times greater than the odds of having NCDs among women who were underweight.ConclusionThe findings revealed that smoking and using smokeless tobacco and alcohol consumption were risk factors of NCDs in women. The findings also alarm the focus of maternal and child health programs on NCDs’ risk factors like maternal obesity, due to their adverse health consequences on their children too. Also, the coexistence of higher levels of tobacco use and alcohol consumption requires different strategies to address the vulnerability of women towards NCDs, including screening and early detection of NCDs especially among those who smoke or chew tobacco and consume alcohol.
Notch1 activation of Jagged1 contributes to differentiation of mesenchymal stem cells into endothelial cells under cigarette smoke extract exposure
Authors: Cheng Yi , Gu Wen , Zhang Guorui , Guo Xuejun 
Published: April 2022

Abstract
Background
Mesenchymal stem cells (MSCs) have shown therapeutic potential for engraftment to, differentiation into, endothelial cells (ECs). However, low-efficiency yields hinder their use as ECs for therapeutic vascularization.

Methods
The Notch1 signaling pathway is key to optimal pulmonary development. Recent evidence has shown that this pathway participated in angiogenesis. Herein, we found that in MSCs, Jagged1 was a target for Notch 1, resulting in a positive feedback loop that propagated a wave of ECs differentiation.

Results
In vitro, Jagged1 was found to be activated by Notch1 in MSCs, resulting in the RBP-Jκ-dependent expression of Jagged1 mRNA, a response that was blocked by Notch1 inhibition. Notch1 promoted the formation of cord-like structures on Matrigel. However, cigarette smoke extract inhibited this process, compared to that in control groups. Moreover, Notch1-overexpressing cells upregulated the expressing of HIF-1α gene. The HIF-1α was an angiogenic factor that clustered with Notch1, underscoring the critical role of Notch1 pathway in vessel assembly. Interestingly, this was abrogated by incubation with Notch1 shRNA.

Conclusions
Notch signaling pathway promotes differentiation of MSCs in to ECs. It also regulates angiogenesis and transcription of specific markers on ECs. These results provide a mechanism that regulates differentiation of MSCs into ECs phenotypes.
Validity, reliability, and responsiveness of the Swedish version of Western Ontario Osteoarthritis of the Shoulder index
Authors: Hallberg Kristofer , Salomonsson Björn 
Published: April 2022

Abstract
Background
The Western Ontario of the Shoulder index (WOOS) is a patient-reported, disease-specific instrument, designed to measure quality of life in patients with osteoarthritis of the shoulder. The Swedish Shoulder Arthroplasty Registry (SSAR) uses WOOS and EuroQoL 5-dimensions 3 levels (EQ-5D-3L) as patient reported outcome measures. The purpose of this study was to test the validity, responsiveness, and reliability of the Swedish translation of WOOS for patients with osteoarthritis of the shoulder.

Methods
Data was collected from three shoulder arthroplasty studies performed during 2005–2013, with 23, 21, and 19 patients respectively. Forms were collected preoperatively, and postoperatively between 12 and 24 months. WOOS and EQ-5D-3L were used in all three studies. Additionally, the Oxford Shoulder Score (OSS) (n = 23) was used in one study, and the Constant-Murley score (CMS) (n = 40) in two of the studies. Validity was analysed by calculating Pearson’s correlation coefficient (PCC). Cronbach’s alpha (CA) was used to estimate internal consistency and reliability. The responsiveness of WOOS was measured by calculating effect size and standardized response mean. To assess the performance of WOOS over time, we present repeated measures of WOOS in the registry over a 10-year period.

Results
The validity analysis showed excellent correlations of WOOS to CMS, OSS and EQ-5D 3L, with Pearson’s correlation coefficient of 0.72, 0.83, and 0.62 respectively (P < 0.001). There were adequate floor effects in the sport and lifestyle domains preoperatively, and adequate ceiling effects in all domains postoperatively. There were no floor effects and adequate ceiling effects for total WOOS. Analyzing reliability, Cronbach’s alpha was 0.95 for the pre- and postoperative WOOS scores combined. The analysis of responsiveness for WOOS showed an effect size of 2.52 and a standardized response mean of 1.43.
The individual results measured by WOOS within the registry shows stable levels from 1 to 10 years.

Conclusion
The Swedish translation of WOOS is valid, reliable, and responsive for use in a clinical setting for patients with glenohumeral osteoarthritis treated with shoulder arthroplasty, and we regard it as an appropriate instrument for use in the Swedish Shoulder Arthroplasty Registry.

Abstract
Background
The concept of pediatric palliative care (PPC) is applied differently within the healthcare system and among healthcare professionals (HCPs). To our knowledge, no studies have investigated how multidisciplinary HCPs understand the concept of PPC and the aim of this study was to explore the concept of PPC from the view of HCP in a paediatric setting.

Methods
We employed an explorative and descriptive design and conducted four focus groups with a total of 21 HCPs working in hospitals with children in palliative care. The data were analysed using qualitative content analysis.

Results
The data analysis of the concept of pediatric palliative care resulted in two themes. The first theme “A frightening concept that evokes negative emotions,” contains categories to explore the meaning, named “An unfamiliar and not meaningful concept, “A concept still associated with death and dying” and “Healthcare professionals’ responsibility for introducing and using the concept and, to obtain a common meaning.” The second theme was named “A broad and complementary concept,” containing the categories “Total care for the child and the family,” “Making room for life and death at the same time” and “The meaning of alleviation and palliative care.”

Conclusions
The included HCPs reflected differently around PPC but most of them highlighted quality of life, total care for the child and the child’s family and interdisciplinary collaboration as core elements. Attention to and knowledge among HCPs might change the perception about PPC from a frightening concept to one that is accepted by all parties, implemented in practice and used as intended. However, our study reveals that there is still some work to do before PPC is understood and accepted by all those involved.

AbstractBackgroundAiming at the poor quality of small lectures due to the lack of lecturing skills of the clinical teachers in residency standardized training, the Teaching and Training Department of Shanghai East Hospital set up a continuous improvement project of lecturing skills for the clinical teachers to search for effective ways to improve lecture quality, then the effect was evaluated.MethodsBased on the ADDIE model of training design, the department conducted the project in accordance with a process of analysis, design, development, implementation and evaluation. A special course “Clinical Teacher Presentation Training” (CTPT) was developed to convey and train the 5 key behaviors in presentation to improving lecture quality of the clinical teachers. Ninety-nine clinical teachers who give lectures to the residents were recruited as subjects for the project. Adopted the model of “intensive training + practice transference” to strengthen lecturing skills, and applied the Kirkpatrick Four Levels to evaluate the effect of the project from multi-role and multi-stage.ResultsThe training satisfaction of the CTPT course from the subjects reaches 100%. The subjects have a high degree of knowledge acquisition through CTPT and the knowledge of the 5 key behaviors has been actually used in their lectures at the stage of practice transference. Comparing the data before training and after transference, it is found that the average increasing of the subjects’ 5 key behavior scores made by teaching secretaries is 14.12 points (14.12%) and that of the subjects’ self-efficacy scores is 9.31 points (9.31%); the performance values were modeling based on the scores from different types of evaluators and increased by an average of 12.61 points (12.61%); and the star ratings of the overall performance increased by an average of 1.17 points (23.4%). The results showed statistically difference (P < 0.001).ConclusionsThe project effectively promoted the improvement of the clinical teachers’ lecturing skills and the quality of small lectures.

Abstract
Background
Radial artery cannulation is a crucial investigative procedure for measuring patients’ blood pressure invasively and serial blood gases. However, radial artery cannulation can be challenging for medical residents, and it is necessary to establish a facile and straightforward teaching strategy. This study aimed to evaluate the efficiency of acoustic shadowing-facilitated ultrasound guidance on radial artery cannulation teaching for medical residents.

Methods
A total of 116 medical postgraduates who underwent standardized residency training programs in the Department of Anesthesiology were randomly divided into a new ultrasound-guided teaching group and a traditional ultrasound-guided teaching group. In the new ultrasound-guided teaching group, radial artery puncture technique was taught by acoustic shadowing-facilitated ultrasound guidance. The training included both theoretical and practical components. After the training, the success rate of the first puncture attempt, the success rate of the catheterization, the ultrasonic positioning time, and the catheterization time of the two groups were compared in a unified manner. A questionnaire on the subjective evaluation of the various aspects of the program by participants was conducted at the end of the training period.

Results
The study included 101 medical residents. The success rate for radial artery puncture at the first attempt in the new ultrasound-guided teaching group was 78.43%. It was significantly higher than that of the traditional ultrasound-guided group (58.00%, odds ratio = 0.380; 95% CI = 0.159 to 0.908; p = 0.027). The success rate for the first arterial catheterization in the new ultrasound-guided teaching group was significantly higher than that of the traditional ultrasound-guided group (74.51% vs. 52.00%, odds ratio = 0.371; 95% CI = 0.160 to 0.858; p = 0.019). The ultrasonic positioning time and catheterization time in minutes in the new ultrasound-guided teaching group were significantly shorter than that of the traditional ultrasound-guided group (14.36 ± 3.31 vs. 18.02 ± 4.95, p < 0.001; 10.43 ± 2.38 vs. 14.78 ± 8.02, p = 0.012). However, no significant differences were observed in the incidence of local hematomas and teaching satisfaction scores between the two groups.

Conclusion
Acoustic shadowing facilitates ultrasound-guided radial artery puncture and catheterization is beneficial in the standardized training and teaching of residents. It improves the success rate of the first attempt at radial artery puncture and catheterization and shortens the time of ultrasound location and catheterization.

Nasal and tracheobronchial nitric oxide production and its influence on oxygenation in horses undergoing total intravenous anaesthesia
Authors: Wilkens Henriette L. , Neudeck Stephan , Kästner Sabine B. R. 
Published: April 2022

AbstractBackgroundThe present study aimed to investigate the effect of endotracheal intubation on nasal and tracheal endogenous NO concentrations, gas exchange and oxygenation in horses undergoing general anaesthesia. In many species a major part of physiological nitric oxide (NO) production takes place in the nasopharynx. Inhaled NO acts as a pulmonary vasodilator and regulates lung perfusion and endotracheal intubation bypasses the nasopharynx. Six horses were randomly assigned to either the “intubated” (INT) or the “non-intubated” (nINT) treatment group. Horses were premedicated with dexmedetomidine (5 μg/kg IV). Anaesthesia was induced with 2.5 mg/kg ketamine and 0.05 mg/kg diazepam IV, and it was maintained by administration of a triple-drip (100 mg/kg/h guaifenesin, 4 mg/kg/h ketamine, 7 μg/kg/h dexmedetomidine). The horses were spontaneously breathing room air. Heart rate, cardiac output, arterial blood pressure, pulmonary arterial blood pressures and respiratory rate were recorded during a 100-min anaesthesia period. Arterial, venous and mixed venous blood samples were taken every 10 minutes and analysed for partial pressure of oxygen (PO2) and carbon dioxide (PCO2), oxygen saturation and haemoglobin content. Standard oxygenation indices were calculated. Nasal and tracheal endogenous NO concentration was determined by chemiluminescence.ResultsCardiovascular variables, respiratory rate, PO2, PCO2, oxygen saturation, haemoglobin content, CaO2, O2ER, P(a-ET)CO2and Qs/Qtdid not differ significantly between the two treatment groups. The P(A-a)O2was significantly higher in INT (6.1 ± 0.3 kPa) compared to nINT (4.9 ± 0.1 kPa) (p = 0.045), respectively. The nasal (8.0 ± 6.2 ppb) and tracheal (13.0 ± 6.3 ppb) endogenous NO concentration differed significantly in INT (p = 0.036), but not in nINT (nasal: 16.9 ± 9.0 ppb; tracheal: 18.5 ± 9.5 ppb) (p = 0.215).ConclusionEndotracheal intubation reduces the nasal and tracheal endogenous NO concentration. The influence on pulmonary gas exchange and oxygenation is negligible in horses breathing room air.

Abstract
Background
Global distributions and trends of the risk-attributable burdens of chronic obstructive pulmonary disease (COPD) have rarely been systematically explored. To guide the formulation of targeted and accurate strategies for the management of COPD, we analyzed COPD burdens attributable to known risk factors.

Methods
Using detailed COPD data from the Global Burden of Disease study 2019, we analyzed disability-adjusted life years (DALYs), years lived with disability (YLDs), years of life lost (YLLs), and deaths attributable to each risk factor from 1990 to 2019. Additionally, we calculated estimated annual percentage changes (EAPCs) during the study period. The population attributable fraction (PAF) and summary exposure value (SEV) of each risk factor are also presented.

Results
From 1990 to 2019, the age-standardized DALY and death rates of COPD attributable to smoking and household air pollution, occupational particles, secondhand smoke, and low temperature presented consistently declining trends in almost all socio-demographic index (SDI) regions. However, the decline in YLD was not as dramatic as that of the death rate. In contrast, the COPD burden attributable to ambient particulate matter, ozone, and high temperature exposure showed undesirable increasing trends in the low- and low-middle-SDI regions. In addition, the age-standardized DALY and death rates attributable to each risk factor except household air pollution and low temperature were the highest in the low-middle-SDI region. In 2019, the COPD burden attributable to smoking ambient particulate matter, ozone, occupational particles, low and high temperature was obviously greater in males than in females. Meanwhile, the most important risk factors for female varied across regions (low- and low-middle-SDI regions: household air pollution; middle-SDI region: ambient particles; high-middle- and high-SDI region: smoking).

Conclusions
Increasing trends of COPD burden attributable to ambient particulate matter, ozone, and high temperature exposure in the low-middle- and low-SDI regions call for an urgent need to implement specific and effective measures. Moreover, considering the gender differences in COPD burdens attributable to some risk factors such as ambient particulate matter and ozone with similar SEV, further research on biological differences between sexes in COPD and relevant policy-making of disease prevention are required.
