Abstract
Background Social problems and suffering from treatment process for infertile couples requires the couples use coping strategies for balancing the infertility crisis. According to the close interactions of the couples with each other, the objective of the study was assess of interrelationships between coping strategies of the infertile couples under assisted reproductive treatment and women’s psychological symptoms.Method This cross sectional research was done on 212 infertile couples undergoing assisted reproductive treatment. The using level of coping strategies, the stress, anxiety and depression levels were evaluated by using valid questionnaire. The relations between the coping strategies of the couples with each other, and also women’s stress, anxiety and depression levels were evaluated.Results The results showed the relationship between using the coping strategies by men, except understanding emotion, maintaining optimism strategies, and the coping strategies by women showed a significant relation. The results showed that the stress, anxiety and depression levels of women were positively related to the using of self-focused rumination and other blame strategies.Conclusion The couples’ coping strategies toward infertility are interacted and psychological symptoms in women’s are affected by their partners’ coping strategies and using of self-focused rumination and other blame strategies by men may effect on partners’ psychological health.

Abstract
Background

Near-Infrared (NIR) fluorescence imaging is a novel technique for intraoperative sentinel lymph node (SLN) identification. It has demonstrated promising results in several surgical specialties. The study aims to evaluate the feasibility of identifying the SLN by indocyanine green (ICG) enhanced NIR endoscopy in squamous cell carcinoma of the oral cavity (OCSCC).
Methods

Five patients with (cT1-3N0) OCSCC were included. We injected 1–1.25 ml of ICG (5 mg/ml) at four to five points around the primary. After the elevation of a platysma flap and posterior retraction of the sternocleidomastoid muscle, fluorescence images were taken with the IMAGE1 S™ NIR/ICG system to define the SLN(s). We sampled fluorescence marked SLN(s) stratified to lymph node levels, followed by level-specified elective neck dissection.
Results

The detection of at least one uni- or bilateral SLN (range 1–4) was possible in every case. The fluorescence signal occurred, on average, 4.8 ± 2.6 minutes after injection. There was no case of neck metastasis in SLN (0/13) and non-SLN (0/189). No adverse reactions to ICG occurred.
Conclusions

Our first results are confirming the concept of SLN concerning OCSCC after the application of real-time NIR fluorescence endoscopy. However, this has to be verified by more extended studies.

Abstract
Background Exposure to secondhand smoke during pregnancy can cause pregnancy complications and adverse birth outcomes. About 40% of Chinese expectant fathers are smokers and they rarely attempt to quit smoking. There is a paucity of effective smoking cessation services targeting this population. In this study, we assessed the smoking behavior of Chinese expectant fathers and examined its association with smoking abstinence after their partner became pregnant, which is an essential prerequisite for designing effective smoking cessation interventions.Methods We conducted a cross-sectional survey in the obstetrics and gynecology clinic of three tertiary hospitals in China. Expectant fathers who smoked at least one cigarette per day for 1 month within the past 12 months were invited to participate in this study. The participants were asked to complete a structured questionnaire that assessed their smoking behaviors before and after their partner became pregnant.Results From December 2017 to March 2018, we recruited a total of 466 eligible expectant fathers, among whom 323 (69.3%) were identified as current smokers and 143 (30.7%) were ex-smokers. Using lasso regression, 19 features were selected from among 27 independent variables. The results of the selected multivariable logistic regression model showed that knowledge about the health hazards of smoking among smokers (odds ratio (OR) 1.39; 95% confidence interval (CI) 1.24 to 1.58; p < 0.001), knowledge about the health hazards of SHS among pregnant women (OR 1.46; 95% CI 1.09 to 1.97; p < 0.001), knowledge about harm to the fetus and newborn (OR 1.58; 95% CI 1.25 to 2.03; p < 0.001), and being a first-time expectant father (OR 2.08; 95% CI 1.02 to 3.85; p = 0.046) were significantly positively associated with smoking abstinence among expectant fathers after their partner became pregnant. Significantly negative associations were found for severe dysfunctionality in terms of family support (OR 0.48; 95% CI 0.24 to 0.95; p = 0.036) and smoking only outside the home (OR 0.81; 95% CI 0.26 to 0.98; p < 0.001).Conclusions In this study, we identified several factors associated with smoking abstinence among expectant fathers after their partner became pregnant. These findings can guide the development of effective interventions targeting expectant fathers, to help them quit smoking.
Energy-efficient hierarchical routing in wireless sensor networks based on Fog Computing

Published: April 2020

Abstract
Wireless sensor networks (WSNs) have been recognized as one of the most essential technologies of the 21st century. The applications of WSNs are rapidly increasing in almost every sector because they can be deployed in areas where cable and power supply are difficult to use. In the literature, different methods have been proposed to minimize energy consumption of sensor nodes so as to prolong WSNs utilization. In this article, we propose an efficient routing protocol for data transmission in WSNs; it is called Energy-Efficient Hierarchical routing protocol for wireless sensor networks based on Fog Computing (EEHFC). Fog computing is integrated into the proposed scheme due to its capability to optimize the limited power source of WSNs and its ability to scale up to the requirements of the Internet of Things applications. In addition, we propose an improved ant colony optimization (ACO) algorithm that can be used to construct optimal path for efficient data transmission for sensor nodes. The performance of the proposed scheme is evaluated in comparison with P-SEP, EDCF, and RABACO schemes. The results of the simulations show that the proposed approach can minimize sensor nodes’ energy consumption, data packet losses and extends the network lifetime.

Published: April 2020

Abstract
Direction of arrival (DOA) estimation has been discussed extensively in the array signal processing field. In this paper, we focus on the DOA information which is defined as the mutual information between the DOA and the received signal with complex additive white Gaussian noise. A theoretical expression of DOA information with multiple sources is presented in the uniform linear array. Specially, the upper bound of DOA information for sparse sources with high SNR is derived and compared with the information of single source. Moreover, the relationship between Cramer-Rao bound and the upper bound of DOA information is given. Finally, the paper investigate the performance evaluation of estimation based on the DOA information. We define the entropy error (EE) as a new performance evaluation index and find that EE is better than mean square error. Moreover, the lower bound of the EE can be regarded as the Generalized Cramer-Rao bound considering the sources' order in multi-source scenario.

Published: April 2020

Abstract
Background
Depression is a common co-morbidity in asthma, worsening asthma control and impairing patient’s quality of life. Previous studies have reported a higher risk of cognitive deficit in depression. However, few research has focused on the cognitive status of asthmatic patients with depression. Evidence showed that inflammation may play an important role in both asthma and depression. Moreover, cerebral white matter injury, which could be induced by inflammation, has been associated with depression. The present study aimed to assess the cognitive function and explore the potential mechanism in patients with asthma, depression and comorbidity.
Methods
We admitted four groups: Asthma comorbid Depression group (A + D, n = 26), Depression group (D, n = 25), Asthma group (A, n = 33) and Normal controls (N, n = 28). Cognitive function was assessed by Montreal Cognitive Assessment (MoCA). Various inflammatory cytokines were measured, including interleukin-1β (IL-1β), interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α), high-mobility group box 1(HMGB1) and Netrin-1. Cerebral white matter injury was assessed by serum myelin basic protein (MBP) and myelin oligodendrocyte glycoprotein (MOG), and their correlations with cognitive performance were calculated.
Results
A + D group showed the highest incidence of cognitive deficit with specific affected cognitive domain. Compared to N group, serum levels of IL-6, HMGB1, Netrin-1, MBP and MOG were significantly elevated in A + D group. MOG level was negatively correlated with MoCA score.
Conclusion
Patients with comorbid condition presented more definite, severe cognitive deficit and higher level of inflammatory cytokines. Cerebral white matter injury may account for the cognitive deficit in these patients and MOG could be a potential biomarker of this process.

Authors: Chehelgerdi Mohammad , Ranjbar Reza 
Published: April 2020

Abstract
Background

The present investigation aimed to assess the antibiotic resistance properties and distribution of virulence factors in the Streptococcus spp. isolated from hospital cockroaches.
Methods

Six-hundred and sixty cockroach samples were collected. Cockroaches were vigorously washed with normal saline, and the achieved saline was used for bacterial culture. Isolated Streptococcus spp. were subjected to disk diffusion as well as PCR amplification of virulence factors and antibiotic resistance genes.
Results

Prevalence of S. pyogenes, S. agalactiae and S. pneumonia was 4.82%, 1.66% and 6.96%, respectively. The highest prevalence of S. pyogenes, S. agalactiae and S. pneumonia were found in oriental (5.71%), oriental (2.85%) and American (7.71%) cockroaches, respectively. Cfb (53.93%), cyl (52.8%), scaa (51.68%) and glna (50.56%) were the most commonly detected streptococcal virulence factors. Pbp2b (71.91%), pbp2 × (58.42%), mefA (46.06%), ermB (46.06%) and tetM (46.06%) were the most commonly detected antibiotic resistance genes. Streptococcal spp. exhibited the highest prevalence of resistance against tetracycline (80.89%), trimethoprim (65.16%), and penicillin (56.17%).
Conclusion

To the best of our knowledge, this is the first prevalence report of virulence factors and antibiotic resistance genes in the Streptococcal spp. isolated from American, German and oriental hospital cockroaches. Findings recommended a certain role for cockroaches in the transmission of nosocomial infections and particularly those caused by virulent and resistant Streptococcus spp. in the hospital environment.

Abstract
Background
People increasingly search online for health information. Particularly, parents of patients often use the Internet as a source for health information. We conducted a survey to investigate the online searching behavior of parents of patients < 18 years, admitted for surgery in an Italian pediatric hospital.
Methods
The cross-sectional survey was nested in a prospective cohort study on surgical procedures. Parents of patients undergoing surgical procedures at Bambino Gesù Children's Hospital, Rome, Italy, were enrolled and contacted by phone after the procedure. We recorded socio-demographic data, sex, length of stay following surgery, proximity of residence to the hospital, use of the internet to search for information on the surgery before and after the intervention and effect of information found online.
Results
The majority (91%) of parents of children undergoing surgical intervention used the internet. Of these, 74.3% of parents searched for information before surgery, and 26.1% searched for information after. Most parents searched for information on the care provider’s website. Two thirds of parents reported that information found online had increased their understanding of the child’s condition. Multivariate analyses indicated that families living far from the hospital (> 43 km) were more likely to search for health information (OR 2.3; 95% CI 1.34–4.00), as were families of patients undergoing a major surgery (OR = 2.1; 95% CI 1.04–4.11).
Conclusions
Parents of children undergoing surgery often search online for information on their child’s intervention, in particular those whose child is scheduled for a major surgery and those living far from the hospital. A survey like the present one allows to understand parents’ information needs, to better guide them in online information seeking and to better tailor information provided on the care provider’s website.

Abstract
Background

The Human Immunodeficiency Virus (HIV) is the leading cause of death among adolescents in sub-Saharan Africa. Despite the long-term benefits of antiretroviral therapy (ART), adherence remains low among adolescents due to challenges related to cost, acquisition, and treatment regimen. Sub-optimal adherence to ART is associated with the development of viral resistance, treatment failure, and increased morbidity and mortality. Financial incentives and life skills training interventions have shown early promise in motivating protective behaviors, however, gaps still remain around effective and innovative ways to motivate adolescents to stay in HIV care. In partnership with youth, we developed an intervention to address their social and financial pressures in order to promote adherence.
Methods

A human-centered design approach was utilized to engage adolescents in the initial design of the intervention. Through random sampling, 72 adolescents ages 12–19 were then recruited from two clinics in Rwanda for the pilot study. Adolescents participated in three monthly peer-led life skills trainings at clinics and received financial incentives via mobile money upon clinic attendance and demonstration of suppressed viral load. Semi-structured interviews were then conducted with adolescents, healthcare workers, and caregivers to understand their experiences with the intervention.
Results

Participants responded favorably to the intervention because of the psychosocial, financial, and health benefits it provided. Caregivers felt that adolescents’ moods, attitudes, and overall well-being improved over time. Adolescents used funds to purchase school supplies and save for investments, thus mitigating their financial burdens. Additionally, we learned that logistical challenges such as SIM card registration and mobile phone access must be considered for scale-up of the intervention.
Conclusions

To our knowledge, this is the first intervention designed in partnership with youth in sub-Saharan Africa aimed at removing financial barriers to ART adherence. The findings suggest that involving youth in the design of programs, providing them with financial incentives, and training them to use and invest their money wisely has a positive effect on them and their families. Thus, to improve adherence to ART and retention in care among HIV-positive youth, it is critical to address their socioeconomic and psychosocial needs.

Abstract
Aim The aim of this study was to investigate the influence of caries-affected dentin on bonding effect of deciduous teeth, in turn to provide guidance for caries removal strategy of deciduous tooth caries before bonding. Methods Extracted second deciduous molars with one adjacent surface carious were collected. The half tooth with caries adjacent surface were grouped into the caries-affected group (Group test), while the caries-free half were grouped into the control group (Group control). For the Group test, carious tissue was removed with slow speed ball drill under the indication of caries indicator. For the Group control, at the other side of the occlusal surface sound dentin was prepared to the similar deep level. Single bond Universal was applied according to the manufacture’s instructions. The defective part was filled with Shofu Beautifil II Namer, a commonly used resin composite in pediatric dentistry. Vertical sticks were obtained and subjected to tensile stress test. The morphology of the bonding surfaces were observed by scanning electron microscope and transmission electron microscopy. Results Electron microscope observation showed that there was no significant difference in morphology between caries-affected dentin and normal dentin. The minerals and smear layer were removed after acid etching, and the collagen network of dentin tubules and intertubular dentin was exposed. The surface of caries-affected dentin was relatively rough and partially decomposed. TEM images of the caries-affected deciduous tooth dentin showed that the hydroxyapatite was sparsely distributed in strips. In normal dentin, hydroxyapatite was thicker and denser. The acidic environment produced by the bacteria demineralized the dentin part, which corresponded to the surface morphology of the caries-affected dentin as seen by SEM. There was no significant difference in the micro-tensile strengths between Group test and Group control (P > 0.05). Conclusion In vitro, caries-affected deciduous tooth dentin could achieve similar bonding strength to normal tooth dentin when Single Bond Universal adhesive was applied. The results of this study may provide theoretical basis for partial caries removal strategy of deciduous tooth caries treatment.

Published: April 2020

Abstract
Background
In the Dutch Armed Forces (DAF), low back pain is the third most reported musculoskeletal disorder. For the prognosis of chronic low back pain (CLBP) only limited evidence is available. This observation results in a lack of clarity on prognostic factors that might affect recovery from CLBP in service members.The main objective is to identify general and military-related factors that are associated with the level of recovery in DAF service members with CLBP who followed a rehabilitation program.
Methods
One hundred five consecutive service members with CLBP who completed the rehabilitation program have been included in this prospective observational cohort study. The primary outcome measurement, level of disability, was used to distinguish a recovered and non-recovered group. Level of pain and self-perceived recovery were used as secondary outcome measurements. Disability and pain were measured at baseline and 12 weeks follow-up and self-perceived recovery only at follow-up. Differences were evaluated within and between the groups using the Student’s t-test, according to the normality of the data distribution. Bivariate logistic regression analyses were used for identifying the prognostic factors related to various outcomes of recovery.
Results
After following the rehabilitation program, 64.8% of the service members recovered from CLBP. In the recovered group, there are significant effect sizes of -6.72 (CI: -7.57 - -5.87) in the level of disability and − 2.58 (CI: -3.17- -1.98) in level of pain, whereas the non-recovered group shows a non-significant effect size of -0.49 (CI: -1.27 - -0.29) in level of disability and a significant effect size of -0.94 (CI: -1.62 - -0.25) in level of pain. The self-perceived recovery in the recovered group is on average “much improved” and in the non-recovered group “slightly improved”. The results of the bivariate regression analyses show no significant independent prognostic factors related to recovery.
Conclusion
In this study, no significant independent prognostic factors could be identified that are associated to the various outcomes of recovery in service members with CLBP who followed a rehabilitation program.
