Published: March 2020

Background Recent Iraqi and Syrian immigrant families are exposed to stress, anxiety, and depressive symptoms due to civil war. Recruitment challenges specific to conducting research within this population include the lack of knowledge about research, stigma of mental illness, and mistrust. Purposes Among immigrant Iraqi and Syrian families: (1) evaluate the approach to recruitment and retention; and (2) evaluate the acceptability of the study procedures. Methods This feasibility study was conducted based on the work of Orsmond and Cohn. It is focused on the evaluation of recruitment capability and resulting sample characteristics and evaluation of acceptability and suitability of the study procedures. Mother–father–infant triads were recruited from a community center. Parents completed questionnaires about stress and depressive symptoms. Buccal swab samples were obtained from the triads to measure telomere length, and infant hair samples were obtained to measure cortisol level. Telomere length and hair cortisol were utilized as measures of chronic stress. Results Ten mother–father–infant triads were enrolled out of 11 approached. Challenges faced this study included inability to reach families by telephone and the effect of cultural norms where the husband’s permission was needed before proceeding, resulting in a slow pace of recruitment. The study strategy and procedures appeared to be feasible as all of the families who participated completed all study protocols. Conclusion This study provides feasibility data to inform the launching of a larger study to examine the associations of family stress with infant stress and development. These findings from Iraqi and Syrian families may be generalizable to studies seeking to recruit these and other immigrant and refugee population families.

Published: March 2020

There is substantial evidence that stem and progenitor cells secrete trophic factors that have potential for repairing injured tissues. We have previously reported that the conditioned medium (CM) obtained from endothelial progenitor cells (EPC) cultures protects striatal neurons against 3-nitropropionic acid-induced toxicity. In the present study we tested the hypothesis that EPC-CM may support cortical neuronal cell function and/or survival. EPC were isolated from the peripheral blood of healthy human donors and cultured in hypoxic conditions (1.5% O2) to stimulate the secretion of growth factors. The supernatant or conditioned medium (EPC-CM) was then collected and used for the various experiments. Primary cultures of cerebral cortex from fetal rat embryonic day 14 were treated with EPC-CM and challenged by glucose and serum deprivation. We observed that EPC-CM treatment significantly increased total cell number and cell viability in the cultures. Similarly, the number of lba1-expressing cells was significantly upregulated by EPC-CM, while western blot analyses for the astroglial marker glial fibrillary acidic protein did not show a marked difference. Importantly, the number of beta-lll-tubulin-positive neurons in the cultures was significantly augmented after EPC-CM treatment. Similarly, western blot analyses for beta-III-tubulin showed significant higher signal intensities. Furthermore, EPC-CM administration protected neurons against glucose- and serum deprivation-induced cell loss. In sum, our findings identified EPC-CM as a means to promote viability and/or differentiation of cortical neurons and suggest that EPC-CM might be useful for neurorestorative approaches.

Background: To our knowledge, there has been no study comparing intubation characteristics between attending and non-attending emergency physicians in Southeast Asia. We aim to identify whether the use of direct laryngoscopy compared to video laryngoscopy affects first-pass success rates between attending emergency physicians and non-attending emergency physicians. Materials and methods: Retrospective analysis of data from 2009 to 2016 in an existing airway registry managed by an academic Emergency Department in Singapore. Primary outcome was first-pass success intubation rate. Secondary outcome was first-pass success rate for difficult intubations. Difficult intubations were defined as LEMON (Look externally, Evaluate 3-3-2 rule, Mallampati score, Obstruction, Neck mobility) score of more than 1. Results: There were a total of 2909 intubations. Attending emergency physicians conducted 1748 intubations, while non-attending emergency physicians conducted 1161 intubations. The first-pass success rates for AEP were 84.2% and 67.4% for non-attending emergency physicians. Direct laryngoscopy was used in 86.2% of intubation by attending emergency physicians compared to 89.0% in the intubation by non-attending emergency physicians. Also, 7.6% of intubations by the attending emergency physicians were difficult compared to 8.8% by the non-attending emergency physicians (p = 0.25). Logistic regression of the effect of laryngoscopy device on first-pass success in all intubations showed a negative association with video laryngoscopy (odds ratio, 0.70; 95% confidence interval, 0.56–0.88). In the subgroup of difficult intubations, non-attending emergency physicians are 1.54 times (95% confidence interval, 0.53–4.42) as likely to have first-pass success with video laryngoscopy compared to that with direct laryngoscopy. On the contrary, in the subgroup of difficult intubations, attending emergency physicians are 0.90 times (95% confidence interval, 0.38–2.12) as likely to have first-pass success with video laryngoscopy compared to that with direct laryngoscopy. Conclusion: Our study showed that video laryngoscopy has a lower first-pass success rate for all intubations in general. Intubations performed by attending emergency physicians with direct laryngoscopy were associated with a higher first-pass success rate.

Published: March 2020

Background: Gravely ill patients admitted to the intensive care unit (ICU), and their families experience acute spiritual and existential needs and often require complex decisions about their care. Little is known about what constitutes chaplaincy care for patients or families in ICUs. Chaplains report that participation in medical decision-making is part of their role. Objective: To describe the spiritual care provided to patients and their families in the ICU. Methods: This was a retrospective observational study of spiritual care for patients and families in the medical ICUs (MICUs) at 4 medical centers over a 3-month period. Inclusion criteria were death in the MICU or discharge to palliative care or hospice. Measures included medical, treatment, and spiritual care information (number of visits, length of visit, chaplain categories, and type of spiritual care provided). Results: Of the 254 patients, 197 (78%) received a total of 485 spiritual care visits. Seventy-seven percent of visits included provision of emotional/spiritual support; only 15% included decision-making support such as family meetings or goals-of-care conversations. The proportion receiving spiritual care increased as patients neared death or discharge. Staff chaplains were involved in goals-of-care conversations to a greater extent than student or part-time chaplains ( P < .05). Conclusion: Spiritual care was provided to most patients and/or families at the end of life. Low chaplain involvement in decision-making in the MICU suggests opportunities to improve chaplains’ contributions to ICU care.

Introduction: There has been a rapid development in minimally invasive pancreas surgery in recent years. The most recent innovation is robotic pancreatoduodenectomy. Several studies have suggested benefits as compared to the open or laparoscopic approach. This review provides an overview of studies concerning patient selection, volume criteria, and training programs for robotic pancreatoduodenectomy and identified knowledge gaps regarding barriers for safe implementation of robotic pancreatoduodenectomy. Materials and methods: A Pubmed search was conducted concerning patient selection, volume criteria, and training programs in robotic pancreatoduodenectomy. Results: A total of 20 studies were included. No contraindications were found in patient selection for robotic pancreatoduodenectomy. The consensus and the Miami guidelines advice is a minimum annual volume of 20 robotic pancreatoduodenectomy procedures per center, per year. One training program was identified which describes superior outcomes after the training program and shortening of the learning curve in robotic pancreatoduodenectomy. Conclusion: Robotic pancreatoduodenectomy is safe and feasable for all indications when performed by specifically trained surgeons working in centers who can maintain a minimum volume of 20 robotic pancreatoduodenectomy procedures per year. Large proficiency-based training program for robotic pancreatoduodenectomy seem essential to facilitate a safe implementation and future research on robotic pancreatoduodenectomy.

Published: March 2020

Background Particulate matter 2.5 (PM2.5) refers to particulate matter with aerodynamic equivalent diameter less than or equal to 2.5 µm, which is an important component of air pollution. PM2.5 aggravates allergic rhinitis (AR) and promotes AR nasal mucosa inflammation. Therefore, the influence of PM2.5 inhalation exposure on microRNA (miRNA) expression profiles and function in the nasal mucosa of AR rats was investigated. Methods Female Sprague Dawley rats were distributed randomly to 2 groups: AR model PM2.5 exposure group (ARE group) and AR model PM2.5-unexposed control group (ARC group). The rats of ARE group were made to inhale PM2.5 at a concentration of 200 µg/m3, 3 h/day, for 30 days. miRNA expression profiles of the nasal mucosa from both groups were determined using an miRNA gene chip and were verified by quantitative real-time PCR (qRT-PCR). Gene function enrichment analysis was performed using bioinformatics analysis. Results The ARE group revealed 20 significantly differentially expressed miRNAs, including 4 upregulated and 16 downregulated miRNAs (fold change > 1.5 or < 0.66, P < .05). Of these, 9 selected miRNAs were verified by qRT-PCR, and the results of 8 miRNAs were in accordance with the miRNA gene chip results, with highly positive correlation ( r = .8583, P = .0031). Numerous target genes of differentially expressed miRNAs were functionally enriched in high-affinity immunoglobulin E receptor signaling, ErbB signaling, mucin O-glycans biosynthesis, transforming growth factor β signaling, mitogen-activated protein kinase signal transduction, phosphatidylinositol signaling, mucopolysaccharide biosynthesis, mammalian target of rapamycin signaling, T cell receptor signaling, Wnt signaling, chemokine signal transduction, and natural killer cell-mediated cytotoxicity pathways. Conclusions PM2.5 causes significant changes in miRNA expression in the nasal mucosa of AR rats. miRNA plays an important role in regulating PM2.5 effects in AR rat biological behavior and mucosal inflammation. This study provides a theoretical basis for the prevention and treatment of AR from the effects of environmental pollution on the gene regulation mechanism.

Published: March 2020

Objective The aim of this study was to differentiate suprasellar germinomas from chiasmatic/hypothalamic gliomas (CHGs) using apparent diffusion coefficient (ADC) values and magnetic resonance imaging (MRI) characteristics. Materials and methods A cross-sectional study was conducted on 11 patients with suprasellar germinomas and 11 patients with CHGs who underwent pretreatment MRI. The ADC values (minimum and average ADC values) of the tumors were measured and the MRI characteristics were evaluated. Results The average and minimum ADC values of suprasellar germinomas were significantly lower than those of CHGs ( p = 0.016 and 0.004 respectively). The selection of 941.15 × 10−6 mm2/s as a cutoff value of the minimum ADC value was used to differentiate suprasellar germinomas and CHGs; the best results were obtained with area under the curve of 0.889, sensitivity of 87.5%, specificity of 77.8% and accuracy of 82.4%. MRI characteristics suggested the diagnosis of suprasellar germinomas were T2W hypointensity and involvement of pituitary gland and/or stalk. MRI characteristics suggested the diagnosis of CHGs was higher degree of contrast enhancement and presence of macrocysts. Conclusion ADC values have a role in differentiating suprasellar germinomas and CHGs, especially when imaging findings on conventional MRI are inconclusive. Furthermore, some MRI features are in favor of differentiation between these tumor entities including tumor location, cyst pattern, T2W hypointensity, degree of contrast enhancement, stalk and pituitary gland involvement.

Published: March 2020

Abstract
Background
Screening for elevated serum alanine aminotransferase (ALAT) can help identifying individuals at the risks of chronic and metabolic diseases, but blood collection is invasive and cannot be widely used for investigations. Considered as simple and inexpensive screening indices, individual characteristics and anthropometric measurements can be measured in a large crowd and may be important surrogate markers for ALAT levels. This study aimed to examine the diagnostic performance of individual characteristics and anthropometric parameters as predictive factors for discerning an elevated ALAT activity among Shenzhen children and adolescents.

Methods
A school-based screening study was performed from 9 high schools in Shenzhen during February 2017 and June 2018. Receiver operating characteristic curve was used to examine the diagnostic performance of each variable for detecting elevated ALAT.

Results
Altogether 7271 students aged 9–17 years were involved. The proportion of elevated ALAT greatly increased with increasing classification of BMI-z. By the sex-specific cut-offs for elevated ALAT (30 U/L boys; 19 U/L girls), BMI showed the highest area under the curve of 0.789 (95% CI 0.765–0.812) and followed by weight (0.779 [0.755–0.802]), BMI-z (0.747 [0.722–0.772]), height (0.622 [0.597–0.647]), and age (0.608 [0.584–0.632]), while height-z was not capable. With the cut-off of 67.8 kg for weight and 22.6 kg/m2 for BMI, the accuracy to identify elevated ALAT was 87.1% for weight and 82.9% for BMI.

Conclusions
The presence of elevated ALAT was more common in overweight or obese children and adolescents. BMI and weight had the superiority of detecting elevated ALAT, followed by BMI-z, height, and age.
“My partner was not fond of using condoms and I was not on contraception”: understanding adolescent mothers’ perspectives of sexual risk behaviour in KwaZulu-Natal, South Africa
Authors: Govender Desiree , Naidoo Saloshni , Taylor Myra 
Published: March 2020

Abstract
Background
Adolescent pregnancy has been a persistent area of interest and concern in the field of public health. The debate about adolescents’ sexual risk behaviour has also gained prominence due to findings that have demonstrated that adolescent girls between 15 and 19 years of age give birth to 16 million infants and account for 62% of new HIV infections in the Caribbean and African regions. Health compromising behaviours often develop in adolescence, yet the sexual and reproductive health of adolescent mothers is often marginalised in the healthcare field. The aim of this study was to explore adolescent mothers’ understanding of sexual risk behaviour.

Methods
The study employed a descriptive qualitative design. To collect the data, four focus group discussions were conducted with adolescent mothers aged 16–19 years. The eighteen adolescent mothers were recruited using purposive sampling technique from a hospital in the Ugu district in KwaZulu-Natal, South Africa. Data were analysed using thematic analysis.

Results
The study revealed that decisions to engage in risky sexual behaviour is influenced by peer pressure, drugs and alcohol, sexual experimentation, myths about contraception, the media, poor parental supervision and power gender dynamics, poverty leading to transactional sex, the vulnerability of young girls, and the fear of partner rejection.

Conclusion
The findings of this study will contribute to a better understanding of adolescent mothers’ perspectives of sexual risk behaviour. In the subject matter of sexual and reproductive health, adolescents’ autonomy with respect to cultural and social recommendations should not be sidelined. Due to their vulnerability, adolescent women are exposed to transactional sex, and it is particularly due to poverty that adolescent women are driven into sexual relations with older men as a means of survival. Moreover, interventions to curb postpartum sexual risk behaviour are important to protect adolescent women and mothers against HIV/AIDS. The sexual and reproductive education of adolescent women should focus on resilience, negotiating skills, and protective decision making. Collaborative efforts to curb sexual risk taking by young women should be encouraged and should involve relevant agents from the educational, social and clinical fields.

Published: March 2020

AbstractBackgroundThe association between fibromyalgia and irritable bowel syndrome is well-established. Alterations in the composition and diversity of the gut microbiome in irritable bowel syndrome have been reported, however, this association is poorly understood in fibromyalgia.Our aim was to summarise the research reporting on the gastrointestinal microbiome and its biomarkers in people with fibromyalgia.MethodsA systematic review of published original research reporting on the gastrointestinal microbiota and its biomarkers in adults with a diagnosis of fibromyalgia was undertaken.ResultsFrom 4771 studies, 11 met our inclusion criteria and were separated into four main groups: papers reportingHelicobacter pylori; other gut bacterial markers; metabolomics and other biomarkers, which included intestinal permeability and small intestinal bacterial overgrowth.ConclusionThe results suggest there is a paucity of quality research in this area, with indications that the gut microbiota may play a role in fibromyalgia within the emerging field of the gut-musculoskeletal axis. Further investigations into the relationship between the gut microbiota, gut dysfunction and fibromyalgia are warranted.
A lower cut-off for lymph node harvest predicts for poorer overall survival after rectal surgery post neoadjuvant chemoradiotherapy
Authors: Yeo Charleen Shanwen , Syn Nicholas , Liu Huimin , Fong Sau Shung 
Published: March 2020

Abstract
Background
A lymph node harvest (LNH) of < 12 is a predictor for poor prognosis in rectal cancer patients. However, neoadjuvant chemoradiotherapy (NACRT) is known to decrease LNH; hence, a cut-off of 12 is inappropriate in such patients. This paper aims to establish a LNH cut-off predictive for disease-free and overall survival in NACRT patients.

Methods
A retrospective review of patients who underwent elective surgery for rectal cancer from 2006 to 2013 was performed. All patients with R1/2 resections and presence of metastases and those operated on for recurrence were excluded. Patient demographics, clinical features, operative details, LNH, 30-day mortality and disease-free and overall survival were recorded. P values of < 0.05 were considered significant.

Results
A total of 257 patients were studied, with 174 (68%) males and a median age of 66 years. Ninety-four (37%) patients received long-course NACRT, and 122 (48%) patients were stage 2 and below. Median LNH was 17, which was reduced in the NACRT group (14 versus 23, P < 0.01). Average length of stay was 9 ± 8 days, with a major post-operative complication rate of 4%. Using hazard ratio plots for the NACRT subgroup, LNH cut-offs of 16.5 and 8.5 were obtained for disease-free survival (DFS) and overall survival (OS) respectively. Survival analysis showed that a LNH cut-off of 8.5 was a significant predictor of OS (P < 0.001).

Conclusion
LNH is reduced in patients receiving NACRT before rectal cancer surgery. A LNH of 9 and above is associated with improved overall survival. We propose that this can be used as a tool for prognosis.
Circular RNA hsa_circ_0004812 impairs IFN-induced immune response by sponging miR-1287-5p to regulate FSTL1 in chronic hepatitis B
Authors: Zhang Liangdong , Wang Zichao 
Published: March 2020

Abstract
Background
The present study aims to explore the functions of circular RNA hsa_circ_0004812 in chronic hepatitis B (CHB) and its underlying molecular mechanisms.

Methods
The expression of circular RNA (circRNA)_0004812 was examined using qRT-PCR and Western blot in blood and liver tissues from CHB patients and healthy volunteers. In the in vitro study, the expression levels of circular RNA hsa_circ_0004812, miR-1287-5p, interferon (IFN)-α, IFN-β were determined using qRT-PCR and Western blotting in HBV-infected hepatoma cells, respectively. Luciferase and biotin pull-down assays were used to investigate the interactions between miR-1287-5p and circ_0004812.

Results
Levels of circ_0004812 were upregulated in CHB patients and HBV-infected hepatoma cells. Knockdown of circ_0004812 increased the expression of IFN-α and IFN-β in HBV-infected Huh7 cells. MiR-1287-5p was identified as a target of circ_0004812 whose overexpression inhibited the expression of miR-1287-5p. Additionally, circ_0004812 promoted the expression of Follistatin-related protein (FSTL) 1 through inhibiting miR-1287-5p. Circ_0004812/miR-1287-5p/FSTL1 axis regulated HBV-induced immune suppression.

Conclusion
Circ_0004812 was identified as a potential target for CHB infection. Circ_0004812 promoted the expression of FSTL1 by inhibiting miR-1287-5p.
