Hyperacusis in children: a scoping review
Authors: Potgieter Iskra , Fackrell Kathryn , Kennedy Veronica , Crunkhorn Rosa , Hoare Derek J.
Published: June 2020

Background

Hyperacusis is a chronic condition commonly defined as a lowered tolerance or increased sensitivity to everyday environmental sounds. It has been viewed as a paediatric disorder which can cause significant impairment to a child’s normal functioning. Although clinical guidance highlights the importance of identifying whether the child has intolerance to loud sounds and managing this appropriately, there are currently no assessment or treatment methods that have been designed and tested for use with children with hyperacusis. A review is therefore indicated to consider the profile of children with hyperacusis as a basis for future research into their assessment and treatment.

Method

A scoping review methodology was followed with literature searches conducted in Embase, PsychINFO, PubMed CENTRAL, Scopus, Web of Science and Google Scholar. Research articles were included if they reported on research studies describing children diagnosed with hyperacusis, providing clinical profile information, and/or reporting on an assessment or management method for children with a primary complaint of hyperacusis. Data were charted on Excel and verified by a second researcher. Twenty-one research articles were included.

Results

Children with hyperacusis are typically described in terms of age at presentation, troublesome sounds, physical sensation, behavioural reactions, coping strategies, comorbid conditions and impact on daily life. Methods of assessing the children include semi-structured interviews, questionnaires, neurological assessment, observation and uncomfortable loudness levels. Management methods include psychological therapy, sound therapy, tinnitus retraining therapy, medication and neuro-rehabilitation.

Conclusion

The information we catalogued on various elements of clinical profile, assessment and management can serve as a stepping stone in future research developing questionnaires for clinical measurement of the impact of hyperacusis on children, and the measurement of treatment related change in clinic and in trials. Positive outcomes were noted by the authors following all of the above treatments; future research must compare these and specify the parameters for optimal results.
Severe constipation as the first clinical manifestation in multiple endocrine neoplasia type 2B: a case report and literature review
Authors: Zhang Lidan , Guo Yan , Ye Lei , Lu Wenli , Dong Zhiya , Wang Wei , Xiao Yuan
Published: June 2020

Background

The occurrence of multiple endocrine neoplasia type 2B (MEN2B) in Asians is very rare. In particular, patients with intractable constipation as the main clinical manifestation are even rarer. Atypical clinical manifestations are likely to lead to a diagnostic delay. In this report, we described a case of a delayed diagnosis of MEN2B, and the first clinical manifestation was intractable constipation.

Case presentation

A female teenager had suffered from intractable constipation since infancy. Because the colonoscopy and biopsy results from local hospitals did not confirm the presence of congenital megacolon, the girl had been followed up at a local clinic for a long time. The diagnosis was not confirmed until thyroid masses were found in the Pediatric Department of Shanghai Ruijin Hospital when she was 12 years old. According to our detailed evaluation, she suffered from Hirschsprung disease (HD), growth retardation, medullary thyroid carcinoma (MTC) and mucosal neuroma due to a mutation in the RET gene. Thus, the diagnosis of MEN2B was confirmed. Afterward, the girl underwent several surgeries and was still being followed up before the article was published.

Conclusion

MEN2B has atypical clinical symptoms in the early stage. Refractory constipation may be the only clinical manifestation that lasts for several years. Therefore, we recommend that early screening and gene sequencing should be performed for patients with severe constipation due to HD to determine the cause of the disease and to improve the survival outcome.

Published: June 2020

Background

Alcohol use during pregnancy is a significant public health problem, ultimately affecting the neonatal offspring. Recent studies explore that no safe amount and safe time to drink alcohol during pregnancy. Even though drinking in pregnancy has a wide range of problems, a small number of scientific publications document on the magnitude of drinking alcohol during pregnancy in Sub-Saharan African countries including Ethiopia. The aim of this study was to assess prevalence and associated factors of alcohol use among pregnant women attending prenatal care at public hospitals, Addis Ababa, Ethiopia.

Methods

Hospital based cross sectional study was employed from May 7 to June 6, 2019 at public hospitals, Addis Ababa. A total of 585 pregnant women participated in the study selected through systematic random sampling technique. Frequency of consumption was measured by using AUDIT. Frequency tables and graphs were used to describe the study variable. The association between variables analyzed with bi-variable and multivariable binary logistic regression. A statistical significance was declared at p value < 0.05 with 95% confidence interval.

Result

A total of 585 participants were included in the study with the response rate of 98.6%. The study showed that the prevalence of alcohol use among pregnant women were 37.1% with (95% CI, 33.2–41). Factors like no formal education [AOR = 3.22, 95%CI, 1.72, 6.02], pre-pregnancy alcohol use [AOR = 3.16, 95%CI, 2.03, 4.91], partner alcohol use [AOR = 3.43, 95%CI, 2.21, 5.32], and poor social support [AOR = 3.16, 95%CI, 1.88, 5.31] were statistically associated with alcohol use during pregnancy.

Conclusion

In this study the prevalence of alcohol use during pregnancy was high as compared to majority of other studies. This study observed that no formal education, pre-pregnancy alcohol use, partner alcohol use, and poor social support, were highly associated with alcohol use during pregnancy. Based on the findings of this study early management of alcohol use and problematic alcohol use is needed for pregnant women.

Authors: Beasley Jeannette M. , Wagnild Janelle M. , Pollard Tessa M. , Roberts Timothy R. , Ahkter Nasima
Published: June 2020

Background

This review examines the effectiveness of diet and physical activity interventions to reduce cardiometabolic risk among Chinese immigrants and their descendants living in high income countries. The objective of this review is to provide information to help build future interventions aimed at improving diet and increasing physical activity levels among Chinese immigrants.

Methods

Outcomes included BMI, weight, waist circumference (WC), waist-hip ratio (WHR), cholesterol (LDL, HDL), systolic and diastolic blood pressure (SBP, DBP), hemoglobin A1c (HgbA1c), fasting blood glucose (FBG), and HOMA-IR. Six databases were systematically searched from database inception to date of search (February 2020). Meta-analyses used random effect models to estimate pooled effects of outcomes with 95% confidence intervals. The outcomes assessed were changes in mean outcomes (post-intervention versus baseline) among the intervention group versus control groups.

Results

Twenty-one articles were included for synthesis, and eight of these were included in the meta-analysis. Among children/adolescents, there were no significant effects of intervention for any of the outcomes having sufficient data for meta-analysis (BMI, WHR, SBP, and DBP). Among adults, the pooled effect including three studies showed significant changes in BMI (effect size = − 1.14 kg/m2; (95% CI: − 2.06, − 0.21), I2 = 31%). There were also significant effects of intervention among adults in terms of changes in SBP and DBP, as the pooled effect across three studies was − 6.08 mmHg (95% CI − 9.42, − 2.73), I2 = 0% and − 3.81 mmHg (95% CI: − 6.34, − 1.28), I2 = 0%, respectively. Among adults there were no other significant effects among the meta-analyses conducted (weight, WC, LDL, HgbA1c, and FBG).

Conclusions

This review is the first to summarize the effectiveness of diet and physical activity interventions specifically designed for Chinese immigrants living in high income countries. There were clinically meaningful changes in BMI and blood pressure among adults, but evidence was weak for other cardiometabolic outcomes (weight, WC, LDL, HgbA1c, and FBG), and among children, there was no evidence of effect for any cardiometabolic outcomes. Given our mixed findings, more work is needed to support the design of successful interventions, particularly those targeting children and their families.

Trial registration

The systematic review protocol was registered in PROSPERO on December 17, 2018, the international prospective register of systematic reviews (registration number: CRD42018117842).

Authors: Moridi Khadijeh , Hemmaty Mohammad , Azimian Amir , Fallah Mohammad Hosein , Khaneghahi Abyaneh Hamid , Ghazvini Kiarash
Published: June 2020

Background

Although many species of mycoplasmas regard as normal flora, but some species causes serious genital disease. In Iran several epidemiological studies have documented the prevalence ofMycoplasma hominis, M. genitaliumandUreaplasma urealyticumin genital disorders. This meta-analysis is going to represent the prevalence ofM. hominis, M. genitaliumandU. urealyticumamong Iranian couples and the correlation between mycoplasmas infection and infertility.

Methods

We search online databases from January 2000 to June 2019. We used following MeSH keywords (Prevalence,M. hominis, M. genitalium, U. urealyticum, male, female, fertility, Infertility, genitourinary tract infection and Iran) with all possible combinations with “OR” and “AND”. Finally, forty-four articles from 2670 were chosen for data extraction and analysis by software using STATA version 14.0.

Results

This meta-analysis revealed that the prevalence ofU. urealyticumwas 17.53% in Iran and the prevalence ofM. genitaliumandM. hominiswere 11.33 and 9.68% respectively. The rate ofM. genitalium,M. hominisandU. urealyticuminfection in women with symptoms of genitourinary tract infection was higher than men with genitourinary tract infection (6.46% vs 5.4, 7.67% vs 5.88 and 21.04% vs 12.13%, respectively). As expected, the prevalence ofM. genitalium,U. urealyticumandM. hominisamong infertile women (12.73, 19.58 and 10.81%) were higher than fertile women (3%, 10. 85% and 4. 35%). Similarly, the prevalence ofM. hominisandU. urealyticumamong infertile men (14 and 21.18%) were higher than fertile men (4 and 3%). Based on this analysis, the rate ofU. urealyticumwas higher thanM. genitaliumandM. hominisamong infertile men and women compared to the fertile group. The prevalence rate ofM. genitalium,M. hominisandU. urealyticumin central provinces is higher than other parts of Iran.

Conclusions

This meta-analysis reemphasizes a significant relationship between the infertility rate andU. urealyticum,M. genitaliumandM. hominisinfections. Our finding help to plan the prevalence map ofM. hominis, M. genitaliumandU. urealyticumin Iran but further studies are needed to suggest routine screening of the pathogens.
Validation of depressive symptoms, social support, and minority stress scales among gay, bisexual, and other men who have with men (GBMSM) in Nigeria, Africa: a mixed methods approach
Authors: Ogunbajo Adedotun , Iwuagwu Stella , Williams Rashidi , Biello Katie B. , Kahler Christopher W. , Sandfort Theodorus G. M. , Mimiaga Matthew J.
Published: June 2020

Background

Gay, bisexual, and other men who have sex with men (GBMSM) in Nigeria experience social marginalization, discrimination and violence due to their sexual identity, which may negatively impact physical, mental, and sexual health outcomes. Studies on GBMSM in Africa utilize measurement scales developed largely for populations in the Global North. The validity and reliability of these instruments—to our knowledge—have never been thoroughly investigated among GBMSM in Nigeria. The aim of the current study was to determine the validity and reliability of the English versions of the Center for Epidemiologic Studies Depression Scale (CESD-R), Multidimensional Scale of Perceived Social Support (MSPSS), and LGBT Minority Stress Measure among a large multi-state sample of GBMSM Nigeria.

Methods

Between January and June 2019, we conducted cognitive interviews (N = 30) and quantitative assessments (N = 406) with GBMSM in Nigeria. The cognitive interviews assessed comprehension of scale items and elicited suggestions for scale modifications. The quantitative assessment was used to gather psychosocial health data and to evaluate psychometric properties and construct validity of the modified scales. We utilized confirmatory factor analysis to assess factor structure, correlation coefficients, and Cronbach’s alpha to examine scale validity and internal consistency.

Results

Based on participant feedback from the cognitive interviews, we made slight modifications (i.e., culturally appropriate word substitutions) to all three scales. Results of quantitative analyses indicated good psychometric properties including high factor loadings, internal consistency and construct validity among the CESD-R, MSPSS, and LGBT Minority Stress Measure among GBMSM in Nigeria.

Conclusion

These results suggests that modifying research scales to be more culturally relevant likely do not jeopardize their validity and reliability. We found that modified scales measuring depressive symptoms, perceived social support, and minority stress among GBMSM in Nigeria remained valid. More research is needed to explore whether the psychometric properties remain if the scales are translated into broken English (Pidgin) and other traditional Nigerian languages (Yoruba, Igbo and Hausa).
Implementation considerations for offering personal genomic risk information to the public: a qualitative study
Authors: Smit Amelia K. , Reyes-Marcelino Gillian , Keogh Louise , Dunlop Kate , Newson Ainsley J. , Cust Anne E.
Published: June 2020

Background

Genomic risk information, based on common genomic susceptibility variants associated with risk of complex diseases such as cancer, may be incorporated into personalised prevention and screening strategies. We aimed to engage with members of the public, who are important stakeholders in this process, to further inform program development and other implementation outcomes such as acceptability and appropriateness.

Methods

Semi-structured interviews were undertaken with 30 participants (aged 24–69 years, 50% female) recruited from a pilot trial in which they received personalised genomic risk information for melanoma. We explored participants’ views and attitudes towards offering general personal genomic risk information to the broader population. The data were analysed thematically.

Results

Two overarching themes relevant to implementation considerations were identified. Firstly, participants’ preferences for accepting an offer of genomic risk information were based on family history, disease incidence and the possibility of prevention. Secondly, participants felt that the processes for offering risk information should be based on individual preferences, triaged according to risk and be supported by a health professional trained in genomics.

Conclusions

Participants felt that offering personal genomic risk information to the general population to inform prevention and early detection recommendations is acceptable, particularly for common, complex conditions such as cancer. Understanding participants’ preferences for receiving genomic risk information will assist with communication strategies and health workforce planning. We anticipate that these findings will contribute to the development of implementation strategies for incorporating genomic risk information into routine clinical practice.
Acceptability and feasibility of the mHealth intervention ‘MyDayPlan’ to increase physical activity in a general adult population
Authors: Degroote L. , Van Dyck D. , De Bourdeaudhuij I. , De Paepe A. , Crombez G.
Published: June 2020

Background

Electronic health (eHealth) and mobile health (mHealth) interventions have the potential to tackle the worldwide problem of physical inactivity. However, they often suffer from large attrition rates. Consequently, feasibility and acceptability of interventions have become important matters in the creation of e- and mHealth interventions. The aim of this study was to evaluate participants’ opinions regarding acceptability and feasibility of a self-regulation, app-based intervention called ‘MyDayPlan’. ‘MyDayPlan’ provides an innovative daily cycle providing several self-regulation techniques throughout the day that guide users towards an active lifestyle via various self-regulation techniques.

Methods

Semi-structured interviews were conducted with 20 adults after using the app for 2 weeks. A directed content analysis was performed using NVivo Software.

Results

‘MyDayPlan’ was well-received and seems to be feasible and acceptable with inactive adults. The straightforward lay out and ease of use of the app were appreciated. Furthermore, the incorporation of the techniques ‘action planning’, and ‘prompting review of behavioral goals’ was positively evaluated. However, the users gave some recommendations: implementation of activity trackers to self-monitor physical activity could be of added value. Furthermore, increasing intuitiveness by minimizing text input and providing more preprogrammed options could further increase the ease of use. Finally, users indicated that they would benefit from more guidance during the “coping planning” component (barrier identification/problem solving), for example by receiving more tailored examples.

Conclusions

Based on these findings, adaptations will be made to the ‘MyDayPlan’ app before evaluating its effectiveness. Furthermore, involving potential end users and evaluating acceptability and feasibility during the development of an e- and mHealth intervention is key. Also, creating interventions with a large ease of use and straightforward layout that provides tailored support during action and coping planning is key.
Incidence, cost and gender differences of oropharyngeal and noncervical anogenital cancers in South Korea
Authors: Choi Inseon , Lee Donghwan , Son Kyung-Bok , Bae SeungJin
Published: June 2020

Background

Human papillomavirus (HPV) is associated with a significant public health burden, yet few studies have been conducted in Asia, especially on noncervical cancers. We estimated the incidence and cost of oropharyngeal and noncervical anogenital (anal, vulvar, vaginal, penile) cancer in Korea.

Methods

We conducted a retrospective cohort study using Korea’s National Health Insurance (NHI) claim database from 2013 to 2016. The main outcome measures were the number of respective cancer incidences during the study period and the annual costs per patient in the first year after diagnosis, which was adjusted by relevant variables based on the regression analysis.

Results

During the study period, 8022 patients with these cancers were identified, and oropharyngeal cancer comprised 46% of them. The crude incidence rate for male oropharyngeal cancer was significantly higher than that of females (3.1 vs. 0.7 per 100,000 as of 2016, respectively). Additionally, the crude incidence of male oropharyngeal cancer increased from 2.7 in 2013 to 3.1 in 2016, whereas that of female and other cancers was stable during the study period. The mean annual incidence-based cost per patient in 2016 was highest for oropharyngeal cancers (21,870 USD), and it was significantly higher in males than in females based on then regression analysis (p < .001).

Conclusions

Oropharyngeal cancer comprises the highest number of HPV-associated noncervical cancer incidences in Korea, and the incidence and cost of oropharyngeal cancer was significantly higher among males than females. More aggressive public health policy toward males may decrease gender gap of oropharyngeal cancer.
Scalpel can achieve better clinical outcomes compared with electric cautery in primary total knee arthroplasty: a comparison study
Authors: Lin Wei , Dai Yike , Niu Jinghui , Yang Guangmin , Li Ming , Wang Fei
Published: June 2020

Background

Whether using the scalpel can provide better and faster recovery after the primary total knee arthroplasty (TKA) is still controversial. The aim of this research was to compare the clinical outcomes of using the scalpel and the electric cautery in primary TKA.

Methods

From January 2016 to December 2017, a retrospective cohort study was conducted in 313 patients who underwent unilateral primary TKA by using the scalpel (group S). During this period, we selected 313 patients who underwent unilateral primary TKA by using the electric cautery (group E) for comparison. The tourniquet time, operative time, blood loss, wound complications, visual analog score for pain, range of motion, Knee Society Score were assessed between the two groups. The Forgotten Joint Score was used to analyze the ability to forget the joint.

Results

There were no significant differences in tourniquet time, operative time, blood loss between the two groups (p > 0.05). In the group S, the visual analog score for pain, range of motion, Knee Society Score were found better results at 1 week, 1 month, 3 months, 6 months, 12 months and 24 months after surgery (p < 0.05). Besides, during the follow-up period, the Forgotten Joint Score was significantly higher compared with group E (p < 0.05).

Conclusion

In this research, the patients who underwent TKA by using the scalpel could achieve better clinical outcomes. In addition, if forgotten artificial joint after TKA was the final goal, the patients who underwent TKA by using the scalpel would acquire better quality of life.
Thickness change of masseter muscles and the surrounding soft tissues in female patients during orthodontic treatment: a retrospective study
Authors: Pan Yichen , Chen Si , Shen Linhui , Pei Yuru , Zhang Yungeng , Xu Tianmin
Published: June 2020

Background

Facial esthetics is a major concern of orthodontic patients. This study aims to evaluate orthodontic treatment-related thickness changes of the masseter muscles and surrounding soft tissues and the potential factors that would influence these changes during orthodontic treatment in female adults.

Methods

Forty-two female adult patients were included in this retrospective study and were divided into extraction (n = 22) and nonextraction (n = 20) groups. Pretreatment and posttreatment cone-beam computed tomography (CBCT) images were superimposed and reconstructed. The thickness changes of the masseter area of facial soft tissue (MAS), masseter muscles (MM) and surrounding fat tissue (FT) were measured. Pretreatment age, treatment duration, sagittal relationship (ANB), and vertical relationship (Frankfort-mandibular plane angle, FMA)-related MAS, MM and FT changes were compared between extraction and nonextraction groups. Spearman’s correlation coefficient was calculated between the above variables. Regression analysis was conducted to confirm the causal relations of the variables.

Results

The thickness of MAS and MM significantly decreased in both groups, with larger decreases (> 1 mm) in the extraction group. There were strong correlations (r > 0.7) between the thickness decrease in MAS and MM in both groups and moderate correlations (r > 0.4) between MAS and FT in the nonextraction group. A significantly greater decrease of MAS and MM were found to be moderately correlated with a smaller FMA (r > 0.4) in the extraction group. Scatter plots and regression analysis confirmed these correlations.

Conclusions

Masseter muscles and the surrounding soft tissue exhibited a significant decrease in thickness during orthodontic treatment in female adults. Low-angle patients experienced a greater decrease in soft tissue thickness in the masseter area in the extraction case. But the thickness changes were clinically very small in most patients.
Rare genital malformations in women’s health research: sociodemographic, regional, and disease-related characteristics of patients with Mayer-Rokitansky-Küster-Hauser syndrome

Published: June 2020

Background

The Mayer-Rokitansky-Küster-Hauser syndrome, MRKHS, is a rare (orphan) disease characterized by the aplasia or hypoplasia of the uterus and the vagina. In women's health research, little is known as to how much care provision for patients with MRKHS takes into account their socio-demographic together with their clinical characteristics. This work examines the patients’ socio-demographic characteristics, highlighting issues of inappropriate and deficient provision of care.

Methods

The study was carried out as part of the larger TransCareO project and included a group of N=129 MRKHS patients who underwent surgery between 2008 and 2012. Using a specially developed questionnaire, we analyzed MRKHS patients’ data found both in the clinical documentation of the Department for Women's Health, University Hospital of Tübingen and the patient surveys of the Center for Rare Genital Malformations (CRGM/ ZSGF). Patients who took part in interviews were compared with non-respondents.

Results

Patient respondents and non-respondents did not differ as to the parameters of interest. In most cases, primary amenorrhea was reported as an admission reason. In 24% of patients, a medical intervention (hymenal incision or hormone treatment) already occurred before admission to the Center in Tübingen and proper diagnosis of MRKHS. About one third received in advance inappropriate treatment. During the therapy, more than half of the patients were in a solid partnership. 10% of the family anamneses documented the occurrence of urogenital malformations.

Conclusions

Care provision for MRKHS patients is largely characterized by delayed proper diagnosis and in part, by inappropriate treatment attempts; there are also indications of regional differences. Anamnestic clues such as an asymptomatic amenorrhea or renal abnormalities of unclear origin still fail to result early enough in referral to a center on the basis of suspected MRKHS diagnosis. Urogenital malformations in the family are more common in patients than in the general population. For patients, a wide range of burdens are associated with the diagnosis. Abnormalities compared to their female peers occur, for instance, in the partnership status: MRKHS patients have more rarely a partner.
Analysis of the pharmacological mechanism of Banxia Xiexin decoction in treating depression and ulcerative colitis based on a biological network module
Authors: Yu Ying , Zhang Gong , Han Tao , Huang Hailiang
Published: June 2020

Background

The network pharmacology method was used to predict the active components of Banxia Xiexin decoction, its targets and the key signalling pathways that are activated in the treatment of depression and ulcerative colitis to explore the common mechanism.

Methods

The active components and targets of Banxia Xiexin decoction were obtained by searching the ETCM,TCMSP and TCMIP database. The disease targets of depression and ulcerative colitis were obtained by combining the following the DisGeNET, OMIM,Drugbank,CTD and PharmGKB disease databases. The drug and disease target genes were obtained from the intersection of the herbal medicine targets and the disease targets and were imported into the STRING platform for the analysis of PPI network. The network modules were constructed using Cytoscape software. An analysis of the functional annotations of GO terms and KEGG signalling pathways was performed for each network module. Then, the tissue distribution, sub-cellular distribution and protein attributes of the key targets in the pathway were analysed by the BioGPS, Genecards and DisGeNET databases.

Results

The mechanism of Banxia Xiexin Decoction in the treatment of depression and ulcerative colitis is related to drug reaction, steroid metabolism, lipid metabolism, inflammatory response, oxidative stress response, cell response to lipopolysaccharide, insulin secretion regulation, estradiol response and other biological functions, mainly through the regulation of 5-hydroxytryptamine synaptic, arachidonic acid metabolism, HIF-1 signaling pathway and NF-kappa B signaling pathway can achieve the effect of same treatment for different diseases.

Conclusions

The mechanism of Banxia Xiexin Decoction in treating different diseases involves direct or indirect correlation of multiple signal pathways, mainly involved in drug metabolism and lipid metabolism, but also through comprehensive intervention of the body’s nervous system, immune system, digestive system and other systems. The effective components of Banxia Xiexin Decoction are mainly act on eight key target proteins (such as ALB, IL6, VEGFA, TNF, PTGS2, MAPK1, STAT3, EGFR) to carry out multi-target effect mechanism, biological mechanism of treating different diseases with the same treatment, and related mechanism of overall treatment, which provide theoretical reference for further research on the material basis and mechanism of Banxiaxiexin decoction on antidepressant and prevention and treatment of ulcerative colitis.
Building a Children’s Health Service and System Research Strategy: development and integration in an Australian paediatric healthcare setting
Authors: Littlewood Robyn , Canfell Oliver J. , Tracey Frank
Published: June 2020

Background

Health services and systems research (HSSR) strategies dedicated to paediatric health care and service delivery are limited. Strategies are available but are outdated and yet to be optimised for use in a paediatric health system. We aim to describe the development and integration of a Children’s Health Service and System Research Strategy (CHSSR-S) in Children’s Health Queensland (CHQ), a large specialist quaternary hospital and health service caring for children and young people in Queensland and northern New South Wales, Australia.

Methods

The CHSSR-S was developed using an inductive, bottom-up, participatory systems approach across three phases: (1) Identifying local HSSR capacity; (2) Development; (3) Integration. A HSSR “Champion” was appointed to lead all phases. Clinical, research and system-based stakeholders (n = 14) were individually identified, contacted and participated in dedicated meetings and a workshop to iteratively design the CHSSR-S. A health system-wide CHSSR-S governance committee was established to drive phase three. Health system integration was achieved by multicomponent, action-based strategies.

Results

The final CHSSR-S comprised ten Research Priorities and three Research Enablers, and was successfully integrated within CHQ via a range of platforms. Research Priorities included: (1) Population Health; (2) Adolescent and Young Adult (AYA) Cancer; (3) Indigenous Health; (4); Mental Health; (5) Nutrition and Obesity; (6) Rare Neurodevelopmental Disorders; (7) Sepsis; (8) Screening, surveillance and monitoring; (9) Innovation; and (10) Electronic Medical Record (EMR). Research Priorities were supported by three Research Enablers: (1) Data; (2); Evaluation and Health Economics; and (3) Policy.

Conclusions

The CHSSR-S is the first known paediatric HSSR strategy developed and integrated within a large dedicated paediatric health system. The CHSSR-S may be used to guide global paediatric healthcare systems to prioritise HSSR in their local setting to optimise health service delivery and patient outcomes.

Published: June 2020

Background

Provision of emergency obstetric care is considered the key for maternal mortality reduction worldwide. This study evaluated the impact of community- and facility-based educational programs on provision of emergency obstetric care in Egypt. The study focused on evaluating utilization of the available health services and care seeking behaviors of mothers in the childbearing period.

Methods

We implemented a package of community- and facility-focused educational interventions in two of Egypt’s lowest income governorates. At facility level, health professionals at rural health units from 21 villages over 5 years were trained. Mass media gathering, individual teaching at health facilities, printed materials and home-based care sessions were provided. Collectively, these interventions were designed to focusing on recognition of the early warning signs during pregnancy, delivery and postpartum period for timely referral to hospitals for 20,494 women and adolescents mothers.

Results

The impact of the interventions was highly reflected on the percent of mothers received care during their pregnancy period. Proper antenatal care at governmental or private health facilities was raised dramatically from 0.6 to 59.3% and those who utilized at least one family planning method from 61.4 to 74.4%. Accordingly, the rate of complications significantly reduced during pregnancy (38.1 to 15.1%), during delivery (24.1 to 13.1%) and during postpartum (81.7 to 7.0%). As an impact to the improvement, there was a marked reduction in adolescent pregnancy by 55% and better birth outcome with a reduction in the percent of stillbirth by 11.5%.

Conclusion

It is important to provide a comprehensive package that works at both improving qualities of care as well as empowering women by knowledge to first aid measures at the community level. The cost-effective way to empower mothers to provide first aid measures as emergency obstetric care is to adopt the outreach approach which could be more influential than mass media campaigns for the at-risk and vulnerable and low-income communities.
Phosphatidic acid-dependent localization and basal de-phosphorylation of RA-GEFs regulate lymphocyte trafficking
Authors: Ishihara Sayaka , Sato Tsuyoshi , Du Guangwei , Guardavaccaro Daniele , Nakajima Akihiko , Sawai Satoshi , Kataoka Tohru , Katagiri Koko
Published: June 2020

Background

Lymphocytes circulate between peripheral lymphoid tissues via blood and lymphatic systems, and chemokine-induced migration is important in trafficking lymphocytes to distant sites. The small GTPase Rap1 is important in mediating lymphocyte motility, and Rap1-GEFs are involved in chemokine-mediated Rap1 activation. Here, we describe the roles and mechanisms of Rap1-GEFs in lymphocyte trafficking.

Results

In this study, we show that RA-GEF-1 and 2 (also known as Rapgef2 and 6) are key guanine nucleotide exchange factors (GEF) for Rap1 in lymphocyte trafficking. Mice harboring T cell-specific knockouts of Rapgef2/6 demonstrate defective homing and egress of T cells. Sphingosine-1-phosphate (S1P) as well as chemokines activates Rap1 in a RA-GEF-1/2-dependent manner, and their deficiency in T cells impairs Mst1 phosphorylation, cell polarization, and chemotaxis toward S1P gradient. On the other hand, B cell-specific knockouts of Rapgef2/6 impair chemokine-dependent retention of B cells in the bone marrow and passively facilitate egress. Phospholipase D2-dependent production of phosphatidic acid by these chemotactic factors determines spatial distribution of Rap1-GTP subsequent to membrane localization of RA-GEFs and induces the development of front membrane. On the other hand, basal de-phosphorylation of RA-GEFs is necessary for chemotactic factor-dependent increase in GEF activity for Rap1.

Conclusions

We demonstrate here that subcellular distribution and activation of RA-GEFs are key factors for a directional movement of lymphocytes and that phosphatidic acid is critical for membrane translocation of RA-GEFs with chemokine stimulation.

Published: June 2020

Background

COVID-19 poses one of the most profound public health crises for a hundred years. As of mid-May 2020, across the world, almost 300,000 deaths and over 4 million confirmed cases were registered. Reaching over 30,000 deaths by early May, the UK had the highest number of recorded deaths in Europe, second in the world only to the USA. Hospitalization and death from COVID-19 have been linked to demographic and socioeconomic variation. Since this varies strongly by location, there is an urgent need to analyse the mismatch between health care demand and supply at the local level. As lockdown measures ease, reinfection may vary by area, necessitating a real-time tool for local and regional authorities to anticipate demand.

Methods

Combining census estimates and hospital capacity data from ONS and NHS at the Administrative Region, Ceremonial County (CC), Clinical Commissioning Group (CCG) and Lower Layer Super Output Area (LSOA) level from England and Wales, we calculate the number of individuals at risk of COVID-19 hospitalization. Combining multiple sources, we produce geospatial risk maps on an online dashboard that dynamically illustrate how the pre-crisis health system capacity matches local variations in hospitalization risk related to age, social deprivation, population density and ethnicity, also adjusting for the overall infection rate and hospital capacity.

Results

By providing fine-grained estimates of expected hospitalization, we identify areas that face higher disproportionate health care burdens due to COVID-19, with respect to pre-crisis levels of hospital bed capacity. Including additional risks beyond age-composition of the area such as social deprivation, race/ethnic composition and population density offers a further nuanced identification of areas with disproportionate health care demands.

Conclusions

Areas face disproportionate risks for COVID-19 hospitalization pressures due to their socioeconomic differences and the demographic composition of their populations. Our flexible online dashboard allows policy-makers and health officials to monitor and evaluate potential health care demand at a granular level as the infection rate and hospital capacity changes throughout the course of this pandemic. This agile knowledge is invaluable to tackle the enormous logistical challenges to re-allocate resources and target susceptible areas for aggressive testing and tracing to mitigate transmission.

Objective

This study investigated the influence of Coronavirus Disease 2019 (COVID-19) on lung function in early convalescence phase.

Methods

A retrospective study of COVID-19 patients at the Fifth Affiliated Hospital of Sun Yat-sen University were conducted, with serial assessments including lung volumes (TLC), spirometry (FVC, FEV1), lung diffusing capacity for carbon monoxide (DLCO),respiratory muscle strength, 6-min walking distance (6MWD) and high resolution CT being collected at 30 days after discharged.

Results

Fifty-seven patients completed the serial assessments. There were 40 non-severe cases and 17 severe cases. Thirty-one patients (54.3%) had abnormal CT findings. Abnormalities were detected in the pulmonary function tests in 43 (75.4%) of the patients. Six (10.5%), 5(8.7%), 25(43.8%) 7(12.3%), and 30 (52.6%) patients had FVC, FEV1, FEV1/FVC ratio, TLC, and DLCO values less than 80% of predicted values, respectively. 28 (49.1%) and 13 (22.8%) patients had PImax and PEmax values less than 80% of the corresponding predicted values. Compared with non-severe cases, severe patients showed higher incidence of DLCO impairment (75.6%vs42.5%,p = 0.019), higher lung total severity score (TSS) and R20, and significantly lower percentage of predicted TLC and 6MWD. No significant correlation between TSS and pulmonary function parameters was found during follow-up visit.

Conclusion

Impaired diffusing-capacity, lower respiratory muscle strength, and lung imaging abnormalities were detected in more than half of the COVID-19 patients in early convalescence phase. Compared with non-severe cases, severe patients had a higher incidence of DLCO impairment and encountered more TLC decrease and 6MWD decline.
Cardiovascular and diabetes burden attributable to physical inactivity in Mexico

Published: June 2020

Background

Physical inactivity (PI) is associated with the development of non-communicable chronic diseases. The purposes of this study were to estimate the extent to which the 31% relative increase in PI among 35–64 years old Mexicans between 2006 and 2012 influenced diabetes (T2D) and cardiovascular disease (CVD) incidence and mortality, and to estimate the impact of the World Health Organization recommended 10% and 15% relative decrease in PI on CVD and T2D incidence and mortality by 2025 and 2030, respectively.

Methods

Estimates were derived using the Cardiovascular Disease Policy Model-Mexico, a computer simulation, Markov model. Model inputs included cross-national data on PI levels from 2006 and 2012 measured using the International Physical Activity Questionnaire and the published literature review on the independent relationship between PI and cardiometabolic risk.

Results

The models estimated that the 31% increase in PI resulted in an increase in the number of cases of T2D (27,100), coronary heart disease (10,300), stroke (2200), myocardial infarction (1500), stroke deaths (400) and coronary heart disease deaths (350). A hypothetical 10% lowering of PI by 2025 compared to status quo is projected to prevent 8400 cases of T2D, 4200 cases of CHD, 1000 cases of stroke, 700 cases of MI, and 200 deaths of CHD and stroke, respectively. A 15% reduction resulted in larger decreases.

Conclusions

While the burden of T2D and CVD raised from 2006 to 2012 in association with increased PI, achieving the WHO targets by 2030 could help reverse these trends.

Background

SubmicroscopicPlasmodium falciparuminfections are widespread in many areas. However, the contribution of these infections to symptomatic malaria is not well understood. This study evaluated whether participants with submicroscopicP.falciparuminfections have higher prevalence of fever than uninfected participants in southern Malawi.

Methods

A total of 16,650 children and adults were enrolled in the course of six cross-sectional surveys during the dry season (October–November) and after the rainy season (April–May) between 2012 and 2014 in three districts in southern Malawi. Demographic and socioeconomic data were collected in conjunction with data on clinical histories, use of malaria preventive measures, and anti-malarial medication taken within 2 weeks of the survey. Axillary temperatures were measured, and blood samples were collected forP. falciparumdetection by microscopy and PCR. Participants without malaria parasites detected on microscopy but with a positive PCR forP. falciparumwere defined as having submicroscopic infection. Fever was defined as having any one of: reported fever in the past 2 weeks, reported fever in the past 48 h, or a temperature of ≥ 37.5 °C measured at the time of interview.

Results

SubmicroscopicP. falciparuminfections and fever were both detected in 9% of the study population. In the final analysis adjusted for clustering within household and enumeration area, having submicroscopicP. falciparuminfection was associated with reduced odds of fever in the dry season (odds ratio = 0.52; 95% CI 0.33–0.82); the association in the rainy season did not achieve statistical significance (odds ratio = 1.20; 95% CI 0.91–1.59). The association between submicroscopic infection and fever was consistent across all age groups. When the definition of fever was limited to temperature of ≥ 37.5 °C measured at the time of interview, the association was not statistically significant in either the rainy or dry season.

Conclusions

In this series of cross-sectional studies in southern Malawi, submicroscopicP. falciparuminfection was not associated with increased risk of fever. Submicroscopic detection of the malaria parasite is important in efforts to decrease transmission but is not essential for the clinical recognition of malaria disease.
