AbstractBackgroundMany children and their families are affected by premature birth. Yet, little is known about their healthcare access and adverse family impact during early childhood. This study aimed to (1) examine differences in healthcare access and adverse family impact among young children by prematurity status and (2) determine associations of healthcare access with adverse family impact among young children born prematurely.MethodsThis was a secondary analysis of cross-sectional 2016 and 2017 National Survey of Children’s Health data. The sample included 19,482 U.S. children ages 0–5 years including 242 very low birthweight (VLBW) and 2205 low birthweight and/or preterm (LBW/PTB) children. Prematurity status was defined by VLBW (i.e., < 1500 g at birth) and LBW/PTB (i.e., 1500–2499 g at birth and/or born at < 37 weeks with or without LBW). Healthcare access measures were adequate health insurance, access to medical home, and developmental screening receipt. Adverse family impact measures were ≥ $1000 in annual out-of-pocket medical costs, having a parent cut-back or stop work, parental aggravation, maternal health not excellent, and paternal health not excellent. The relative risk of each healthcare access and adverse family impact measure was computed by prematurity status. Propensity weighted models were fit to estimate the average treatment effect of each healthcare access measure on each adverse family impact measure among children born prematurely (i.e., VLBW or LBW/PTB).ResultsBivariate analysis results showed that VLBW and/or LBW/PTB children generally fared worse than other children in terms of medical home, having a parent cut-back or stop working, parental aggravation, and paternal health. Multivariable analysis results only showed, however, that VLBW children had a significantly higher risk than other children of having a parent cut-back or stop work. Adequate health insurance and medical home were each associated with reduced adjusted relative risk of ≥$1000 in annual out-of-pocket costs, having a parent cut-back or stop work, and parental aggravation among children born prematurely.ConclusionsThis study’s findings demonstrate better healthcare access is associated with reduced adverse family impact among U.S. children ages 0–5 years born prematurely. Population health initiatives should target children born prematurely and their families.
Factors influencing the perceived importance of oral health within a rural Aboriginal and Torres Strait Islander community in Australia

Published: April 2020

Abstract
Background
Indigenous Australians suffer from higher rates of oral disease and have more untreated dental problems and tooth extractions than the general population. Indigenous Australians also have lower rates of accessing oral health services and are more likely to visit for a problem rather than a check-up. Multiple issues effect health service and prevention programs including: characteristics of health services such as distances to health services; existence of social and cultural barriers; available wealth and social support; and, characteristics of the individual and community including the importance given to the disease. This paper seeks to explore the perceived importance of oral health within a rural Indigenous community in Australia and the factors influencing this perception.

Methods
The study used a phenomenology research design incorporating focus group discussions and in-depth interviews. It was undertaken in partnership with communities’ Health Action Group who guided the focus, implementation and reporting of the research. A convenience sample was recruited from established community groups. Thematic analysis on the transcripts was completed.

Results
Twenty-seven community members participated in three focus groups and twelve in-depth interviews. The study found that the community gives high priority to oral health. Factors influencing the importance include: the perceived severity of symptoms of oral disease such as pain experienced due to tooth ache; lack of enabling resources such as access to finance and transport; the social impact of oral disease on individuals including impact on their personal appearance and self-esteem; and health beliefs including oral health awareness. Participants also noted that the importance given to oral health within the community competed with the occurrence of multiple health concerns and family responsibilities.

Conclusion
This paper highlights the high importance this rural Indigenous community gives to oral health. Its findings suggest that under-utilisation of oral health services is influenced by both major barriers faced in accessing oral health services; and the number and severity of competing health and social concerns within the community. The study results confirm the importance of establishing affordable, culturally appropriate, community-based oral health care services to improve the oral health of rural Indigenous communities.

AbstractBackgroundMalignant melanoma (MM) generally presents as a primary neoplasm of the skin, and most MM cases of the respiratory system are metastatic. Primary MM of the lung (PMML) is quite rare, and its diagnosis is relatively difficult.Case presentationWe report the case of a 57-year-old male patient with PMML who denied any history of tumours. His initial complaint was frequent coughs with bloody sputum for 4 days. Chest radiography demonstrated a high-density shadow in the lower lobe of the right lung, which was suspected to be a large space-occupying lesion on subsequent computed tomography (CT) and to be a hypermetabolic tumour by positron emission tomography–CT. To confirm the diagnosis, exploratory surgery was performed. Finally, we confirmed the diagnosis of PMML.ConclusionsPMML is extremely rare and easily misdiagnosed as lung cancer. Because of its morphological and immunophenotypic variations, the diagnosis of PMML remains difficult. This case report discusses the diagnosis and case management of a patient while referring to the existing literature.

Abstract
Background
Improving medication safety is a major concern in primary care settings worldwide. The Salford Medication safety dASHboard (SMASH) intervention provided general practices in Salford (Greater Manchester, UK) with feedback on their safe prescribing and monitoring of medications through an online dashboard, and input from practice-based trained clinical pharmacists. In this study we explored how staff working in general practices used the SMASH dashboard to improve medication safety, through interactions with the dashboard to identify potential medication safety hazards and their workflow to resolve identified hazards.

Methods
We used a mixed-methods study design involving quantitative data from dashboard user interaction logs from 43 general practices during the first year of receiving the SMASH intervention, and qualitative data from semi-structured interviews with 22 pharmacists and physicians from 18 practices in Salford.

Results
Practices interacted with the dashboard a median of 12.0 (interquartile range, 5.0–15.2) times per month during the first quarter of use to identify and resolve potential medication safety hazards, typically starting with the most prevalent hazards or those they perceived to be most serious. Having observed a potential hazard, pharmacists and practice staff worked together to resolve that in a sequence of steps (1) verifying the dashboard information, (2) reviewing the patient’s clinical records, and (3) deciding potential changes to the patient’s medicines. Over time, dashboard use transitioned towards regular but less frequent (median of 5.5 [3.5–7.9] times per month) checks to identify and resolve new cases. The frequency of dashboard use was higher in practices with a larger number of at-risk patients. In 24 (56%) practices only pharmacists used the dashboard; in 12 (28%) use by other practice staff increased as pharmacist use declined after the initial intervention period; and in 7 (16%) there was mixed use by both pharmacists and practice staff over time.

Conclusions
An online medication safety dashboard enabled pharmacists to identify patients at risk of potentially hazardous prescribing. They subsequently worked with GPs to resolve risks on a case-by-case basis, but there were marked variations in processes between some practices. Workload diminished over time as it shifted towards resolving new cases of hazardous prescribing.
CD4+ T cell expression of the IL-10 receptor is necessary for facial motoneuron survival after axotomy

Published: April 2020

AbstractBackgroundAfter peripheral nerve transection, facial motoneuron (FMN) survival depends on an intact CD4+ T cell population and a central source of interleukin-10 (IL-10). However, it has not been determined previously whether CD4+ T cells participate in the central neuroprotective IL-10 cascade after facial nerve axotomy (FNA).MethodsImmunohistochemical labeling of CD4+ T cells, pontine vasculature, and central microglia was used to determine whether CD4+ T cells cross the blood-brain barrier and enter the facial motor nucleus (FMNuc) after FNA. The importance of IL-10 signaling in CD4+ T cells was assessed by performing adoptive transfer of IL-10 receptor beta (IL-10RB)-deficient CD4+ T cells into immunodeficient mice prior to injury. Histology and qPCR were utilized to determine the impact of IL-10RB-deficient T cells on FMN survival and central gene expression after FNA. Flow cytometry was used to determine whether IL-10 signaling in T cells was necessary for their differentiation into neuroprotective subsets.ResultsCD4+ T cells were capable of crossing the blood-brain barrier and associating with reactive microglial nodules in the axotomized FMNuc. Full induction of central IL-10R gene expression after FNA was dependent on CD4+ T cells, regardless of their own IL-10R signaling capability. Surprisingly, CD4+ T cells lacking IL-10RB were incapable of mediating neuroprotection after axotomy and promoted increased central expression of genes associated with microglial activation, antigen presentation, T cell co-stimulation, and complement deposition. There was reduced differentiation of IL-10RB-deficient CD4+ T cells into regulatory CD4+ T cells in vitro.ConclusionsThese findings support the interdependence of IL-10- and CD4+ T cell-mediated mechanisms of neuroprotection after axotomy. CD4+ T cells may potentiate central responsiveness to IL-10, while IL-10 signaling within CD4+ T cells is necessary for their ability to rescue axotomized motoneuron survival. We propose that loss of IL-10 signaling in CD4+ T cells promotes non-neuroprotective autoimmunity after FNA.

Published: April 2020

Abstract
Background
WHO guidelines recommend breastfeeding for mothers living with HIV adherent to antiretroviral therapy in countries where formula is not accessible. In Canada and the US, guidelines for mothers living with HIV recommend exclusive formula feeding. Awareness of national infant feeding guidelines and socio-cultural factors influence infant feeding choices that may result in an increased risk of vertical transmission of HIV. The purpose of this paper is to present factors associated with awareness of guidelines among Black mothers living with HIV. Data were derived from a survey conducted as part of a recent international study that examined infant feeding practices among Black women living with HIV in Ottawa, Canada; Port Harcourt, Nigeria; and Miami, Florida.

Methods
Participants (n = 690) from Port Harcourt (n = 400), Miami (n = 201), and Ottawa (n = 89) were surveyed on their awareness of infant feeding guidelines for mothers living with HIV. Data were collected between November, 2016 and March, 2018.

Results
Participants’ mean ages were 34.3 ± 5.9 years. Across all sites, 15.4% (95% CI 13.2, 7.7) of mothers were NOT aware of their country’s infant feeding guidelines. Cultural beliefs (OR = 0.133, p = 0.004, 95% CI 0.03, 0.53) and functional social support influenced infant feeding choices (OR = 1.1, p = 0.034, 95% CI 1.01, 1.20) and were statistically significant predictors of guideline awareness (Χ2 = 38.872, p < .05) after controlling for age, years of formal education, marital status, and country of residence. As agents of functional social support, family members and health workers (e.g., nurses, physicians, social workers, other health care workers) influenced participants’ awareness of infant feeding guidelines and guided them in their infant feeding choices.

Conclusions
Among participants, awareness of national infant feeding guidelines was associated with functional social support and cultural beliefs influenced infant feeding choices. Therefore, culturally adapted messaging via social supports already identified by mothers, including family relationships and health workers, is an appropriate way to enhance awareness of infant feeding guidelines. Ultimately, contributing to the global health goals of maternal health and reduced infant mortality.
Prenatal infant feeding intentions and actual feeding practices during the first six months postpartum in rural Rwanda: a qualitative, longitudinal cohort study
Authors: Ahishakiye Jeanine , Bouwman Laura , Brouwer Inge D. , Vaandrager Lenneke , Koelen Maria 
Published: April 2020

Abstract
Background
Exclusive breastfeeding (EBF) is advocated by the WHO for the first 6 months. In Rwanda, the percentage of infants who are exclusively breastfed decreases from 94% among infants aged 0–1 month to 81% among those aged 4–5 months. Little is known about what influences mothers’ breastfeeding practices. This study aimed to gain insights into expectant mothers’ prenatal feeding intentions, the underlying reasons, actual practices after birth, and factors facilitating or impeding EBF for the first 6 months of a child’s life in Muhanga District, Rwanda.

Methods
This qualitative longitudinal study, conducted between December 2016 and October 2017 as part of a larger study, recruited a purposive sample of 39 pregnant women attending prenatal consultations during their last trimester in two rural health centers. Women were interviewed during pregnancy, within the first week after birth and at 4 and 6 months postpartum to explore intentions, actual practices, critical transition points, and facilitating or impeding factors. Interviews were recorded, transcribed verbatim, and analyzed thematically.

Results
Of the 39 participants, 38 intended to breastfeed within the first hour after birth, and 32 intended to breastfeed exclusively for the first 6 months. In practice, 34 initiated breastfeeding within the first hour, and 12 breastfed exclusively for 6 months. Impeding factors include perceived breastmilk insufficiency, pressure from family members, past experiences, mothers’ concerns over their infants’ health, mothers’ heavy workload, poverty and food insecurity. Factors facilitating early initiation and EBF include mothers’ awareness of EBF’s advantages, confidence in their breastfeeding ability, and support from health professionals and family members.

Conclusion
Despite participants’ intentions about breastfeeding, there was a gap between intentions and actual practices. An interplay of barriers at individual, group and societal levels impeded women from EBF for the first 6 months. EBF promotion interventions should consider supporting and equipping breastfeeding mothers with skills to deal with perceived breastmilk insufficiency and to recognize the true signs of baby hunger cues. Furthermore, important influential family and community members should be targeted to support mothers to breastfeed. Interventions that consider addressing the issue of poverty-driven food insecurity should not be overlooked either.
Biomechanical study of C1 posterior arch crossing screw and C2 lamina screw fixations for atlantoaxial joint instability
Authors: Liu Chuang , Kamara Allieu , Yan Yunhui 
Published: April 2020

Abstract
Background
The biomechanics of C1 posterior arch screw and C2 vertebral lamina screw techniques has not been well studied, and the biomechanical performance of the constructs cannot be explained only by cadaver testing.

Methods
From computed tomography images, a nonlinear intact three-dimensional C1-2 finite element model was developed and validated. And on this basis, models for the odontoid fractures and the three posterior internal fixation techniques were developed. The range of motion (ROM) and stress distribution of the implants were analyzed and compared under flexion, extension, lateral bending, and axial rotation.

Results
All three kinds of fixation techniques completely restricted the range of motion (ROM) at the C1-2 operative level. The C1-2 pedicle screw fixation technique showed lower and stable stress peak on implants. The C1 posterior arch screw + C2 pedicle screw and C1 pedicle screw + C2 lamina screw fixation techniques showed higher stress peaks on implants in extension, lateral bending, and axial rotation.

Conclusions
As asymmetrical fixations, C1 posterior arch screw + C2 pedicle screw and C1 pedicle screw + C2 lamina screw fixations may offer better stability in lateral bending and axial rotation, but symmetrical fixation C1-2 pedicle screw can put the implants in a position of mechanical advantage.
Epidemiology of rheumatoid arthritis in sub-Saharan Africa: a systematic review and meta-analysis protocol
Authors: Essouma Mickael , Nkeck Jan René , Endomba Francky Teddy , Bigna Jean Joel , Ralandison Stéphane 
Published: April 2020

Abstract
Background
So far, only one meta-analysis has estimated the prevalence of rheumatoid arthritis (RA) in Africa. Out of 10 studies included in that meta-analysis, nine came from sub-Saharan African countries and had been published between 1968 and 1988. We will conduct a new systematic review and meta-analysis to update their estimates and provide more consistent prevalence data on RA in sub-Saharan Africa.

Methods
We will comprehensively search electronic databases to select observational studies addressing RA in sub-Saharan Africa and published as from 1 January 2000: PubMed, EMBASE, African Journals Online, Web of Science, and Global Index Medicus. Summary estimates will be derived through random-effects meta-analysis whenever possible. Alternatively, estimates will be reported through narrative synthesis when the random-effects meta-analysis will be impossible. The risk of bias will be assessed using standard methods.

Discussion
This systematic review and meta-analysis shall quantify the magnitude of RA morbidity and mortality in sub-Saharan Africa. Results from this review will be disseminated in peer-reviewed journals, conferences and on social media platforms.

Published: April 2020

Abstract
Background
Cancer predominates in adults over age 65. Cancer treatments are known to create physical and psychosocial challenges, which may be amplified for older adults with cancer.
Learning and applying self-management behaviours and skills during treatment with cancer can help to manage/recover health and improve quality of life. In many other chronic illnesses, self-management interventions are known to improve health outcomes and lower healthcare costs. The purpose of this systematic review is to determine the effectiveness of self-management interventions for older adults with cancer on physical, psychosocial, and health system-related outcomes.

Methods
We are conducting a systematic review of self-management interventions for older adults (65+) diagnosed with cancer (solid tumour or haematological) in the active treatment phase of cancer. This systematic review is guided by the Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) statement. Studies are limited to experimental or quasi-experimental methods published in English, French, German, or Dutch. A search strategy was designed with a Health Sciences librarian and performed using the following electronic databases: Ageline, AMED, ASSIA, Cinahl, Cochrane, Embase, Medline, PsychINFO, and Sociological Abstracts. Approximately 14,000 titles and abstracts are being electronically screened by a minimum of 2 reviewers, with relevant studies to be screened for full text. The final sample of included studies will be assessed for quality using the Cochrane Risk of Bias tool and Down and Black for quasi-experimental studies, with data synthesized in a narrative and tabular format.

Discussion
This systematic review will expand the knowledge base of interventions supporting self-management for older adults with cancer. This study will inform future intervention development by identifying gaps and strengths in effective self-management interventions targeting the needs of older adults receiving active treatment for cancer.
