Abstract

Background
Malaria remains one of the most important causes of morbidity and death in sub-Saharan Africa. Along with early diagnosis and treatment of malaria cases and intermittent preventive treatment in pregnancy (IPTp), vector control is an important tool in the reduction of new cases. Alongside the use of long-lasting insecticidal nets (LLINs) and indoor residual spraying (IRS), targeting the vector larvae with biological larvicides, such as Bacillus thuringiensis israelensis (Bti) is gaining importance as a means of reducing the number of mosquito larvae before they emerge to their adult stage. This study presents data corroborating the entomological impact of such an intervention in a rural African environment.

Methods
The study extended over 2 years and researched the impact of biological larviciding with Bti on malaria mosquitoes that were caught indoors and outdoors of houses using light traps. The achieved reductions in female Anopheles mosquitoes were calculated for two different larviciding choices using a regression model.

Results
In villages that received selective treatment of the most productive breeding sites, the number of female Anopheles spp. dropped by 61% (95% CI 54–66%) compared to the pre-intervention period. In villages in which all breeding sites were treated, the number of female Anopheles spp. was reduced by 70% (95% CI 64–74%) compared to the pre-intervention period.

Conclusion
It was shown that malaria vector abundance can be dramatically reduced through larviciding of breeding habitats and that, in many geographical settings, they are a viable addition to current malaria control measures.

Abstract

Background
The economic crisis posed various challenges to policy-makers who had to decide on which health policy measures to focus on and on which to refrain from. The aim of this research was to assess the relevance of ethics and to highlight ethical dimensions in decision-taking by policy-makers with regard to policy and priority-setting in health systems posed by the economic crisis.

Methods
Semi-structured qualitative interviews were conducted with eight European policy-makers from six countries.

Results
All interviewees recalled difficult and strenuous situations where they had to prioritise between distinct areas to focus on and invest in, for example around choices between prioritising medications, health professional staffing, care specific equipment, or urgent infrastructure issues. Values could be identified which they deemed as important within the policy-making process, such as trust and responsibility. They explicitly expressed the need for ethical tools and assistance in terms of policy advice for reaching morally sustainable decisions in health policy matters.

Conclusions
The study showed that ethical concepts and values frequently come into play in health policy-making, and that ethics is highly relevant in policy-makers’ daily decision-taking, yet that they lack ethical guidance on what to base their decisions. The study is of relevance since it can provide future decisions on austerity-related issues with an ethical underpinning and could identify areas of moral concern.

Abstract
The methylation of N6 adenosine (m6A) plays a critical role in diverse biological processes. However, knowledge regarding the reconstitution of m6A across cancer types is still lacking. Here, we systematically analyzed the molecular alterations and clinical relevance of m6A regulators across > 10,000 subjects representing 33 cancer types. We found that there are widespread genetic alterations to m6A regulators, and that their expression levels are significantly correlated with the activity of cancer hallmark-related pathways. Moreover, m6A regulators were found to be potentially useful for prognostic stratification, and we identified IGF2BP3 as a potential oncogene across multiple cancer types. Our results provide a valuable resource that will guide both mechanistic and therapeutic analyses of the role of m6A regulators in cancer.

Abstract

Background
A negative status following confirmatory Early Infant Diagnosis (EID) is the desired pediatric outcome of prevention of Mother to Child Transmission (PMTCT) programs. EID impacts epidemic control by confirming non-infected HIV-exposed infants (HEIs) and prompting timely initiation of ART in HIV-infected babies which improves treatment outcomes.

Objectives
We explored factors associated with EID outcomes among HEI in North-Central Nigeria.

Method
This is a cross-sectional study using EID data of PMTCT-enrollees matched with results of HEI’s dried blood samples (DBS), processed for DNA-PCR from January 2015 through July 2017. Statistical analyses were done using SPSS version 20.0 to generate frequencies and examine associations, including binomial logistic regression with p < 0.05 being statistically significant.

Results
Of 14,448 HEI in this analysis, 51.8% were female and 95% (n = 12,801) were breastfed. The median age of the infants at sample collection was 8 weeks (IQR 6–20), compared to HEI tested after 20 weeks of age, those tested earlier had significantly greater odds of a negative HIV result (≤ 6 weeks: OR = 3.8; 6–8 weeks: OR = 2.1; 8–20 weeks: OR = 1.5) with evidence of a significant linear trend (p < 0.001). Similarly, HEI whose mothers received combination antiretroviral therapy (cART) before (OR = 11.8) or during the index pregnancy (OR = 8.4) had significantly higher odds as compared to those whose mothers did not receive cART. In addition, HEI not breastfed had greater odds of negative HIV result as compared to those breastfed (OR = 1.9).

Conclusions
cART prior to and during pregnancy, earlier age of HEI at EID testing and alternative feeding other than breastfeeding were associated with an increased likelihood of being HIV-negative on EID. Therefore, strategies to scale-up PMTCT services are needed to mitigate the burden of HIV among children.

Published: September 2019

AbstractBackgroundFollowing an amputation, the human postural control system develops neuromuscular adaptations to regain an effective postural control. We investigated the compensatory mechanisms behind these adaptations and how sensorimotor integration is affected after a lower-limb transfemoral amputation.MethodsCenter of pressure (CoP) data of 12 unilateral transfemoral amputees and 12 age-matched able-bodied subjects were recorded during quiet standing with eyes open (EO) and closed (EC). CoP adjustments under each leg were recorded to study their contribution to posture control. The spatial structure of the CoP displacements was characterized by measuring the mean distance, the mean velocity of the CoP adjustments, and the sway area. The Entropic Half-Life (EnHL) quantifies the temporal structure of the CoP adjustments and was used to infer disrupted sensory feedback loops in amputees. We expanded the analysis with measures of weight-bearing imbalance and asymmetry, and with two standardized balance assessments, the Berg Balance Scale (BBS) and Timed Up-and-Go (TUG).ResultsThere was no difference in the EnHL values of amputees and controls when combining the contributions of both limbs (p = 0.754). However, amputees presented significant differences between the EnHL values of the intact and prosthetic limb (p <  0.001). Suppressing vision reduced the EnHL values of the intact (p = 0.001) and both legs (p = 0.028), but not in controls. Vision feedback in amputees also had a significant effect (increase) on the mean CoP distance (p <  0.001), CoP velocity (p <  0.001) and sway area (p = 0.007). Amputees presented an asymmetrical stance. The EnHL values of the intact limb in amputees were positively correlated to the BBS scores (EO: ρ = 0.43, EC: ρ = 0.44) and negatively correlated to the TUG times (EO: ρ = − 0.59, EC: ρ = − 0.69).ConclusionThese results suggest that besides the asymmetry in load distribution, there exist neuromuscular adaptations after an amputation, possibly related to the loss of sensory feedback and an altered sensorimotor integration. The EnHL values suggest that the somatosensory system predominates in the control of the intact leg. Further, suppressing the visual system caused instability in amputees, but had a minimal impact on the CoP dynamics of controls. These findings points toward the importance of providing somatosensory feedback in lower-limb prosthesis to reestablish a normal postural control.Trial registrationDRKS00015254, registered on September 20th, 2018.
Humanism influencing the organization of the health care system and the ethics of medical relations in the society of Bosnia-Herzegovina

Published: September 2019

AbstractEvery successful health care system should be based on some general humanistic ideals. However, the nationally organized health care systems of most European countries usually suffer from a deficiency in common ethical values based on universal human principles. When transitional societies, such as that of Bosnia-Herzegovina are concerned, health care organizational models are even more dysfunctional. The sources of a dysfunction in medical care system of Bosnia-Herzegovina are manifold and mutually controversial, including a lack of shared principles, an inappropriate involvement of politicians in medical care and practice, administrative difficulties arising from superficial communication systems, as well as economic limits concerned with the financing of health care. The deficiency of a moral culture of medicine, which is correlated to a general collapse of morality is also responsible for many problems affecting various aspects of life including medical care. Hence, medical ethics from a virtue perspective is becoming an important ingredient of any improvement deigned to provide better-quality medical care.The aim of this paper is to underline the influence of humanism on the organization of health care systems and the ethics of medical interrelations in the society of Bosnia-Herzegovina. It is not intended to diagnose or resolve the problems, but to analyze them. It is also a critique of specific socio-political-economic influences on this health care system, inquiring if well-educated individuals in the virtues, which are involved in medical practice and education, would counteract them.In conclusion, humanism creates a universal ethical structure, which is based on human values such as fidelity, trust, benevolence, intellectual honesty, courage, compassion and truthfulness. These values should represent the standard around which medical care is organized. Since the health care system in Bosnia-Herzegovina is not entirely founded upon humanistic ideals, addressing the socio-political-economic conditions that constantly undermine those values is a prerequisite for any much-needed improvements of the medical care.

Abstract

Background
Leptomeningeal metastasis (LM) is a devastating and terminal complication of advanced non-small-cell lung cancer (NSCLC), especially in patients harboring epidermal growth factor receptor (EGFR) mutations. The role of whole brain radiation therapy (WBRT) in the treatment of EGFR-mutant NSCLC patients with LM is not conclusive. Therefore, we conducted a retrospective study to evaluate the therapeutic effect of WBRT in this setting.

Methods
EGFR-mutant NSCLC patients with LM, who had previously received treatment at the Shandong Cancer Hospital and Institute from July 2014 to March 2018 were reviewed retrospectively. LM was diagnosed by positive CSF cytology and/or leptomeningeal-enhanced magnetic resonance imaging (MRI). Survival was estimated using the Kaplan-Meier method.

Results
In total, 51 EGFR-mutated NSCLC patients with LM were eligible for analysis, subdivided into 26 in the WBRT group and 25 in the non-WBRT group. No significant differences were observed in intracranial ORR (15.4% vs. 16%, p = 0.952) and DCR (34.7% vs. 28%, p = 0.611) between the two groups. The median iPFSLM and OSLM for the entire cohort were 3.3 months (95% CI: 2.77–3.83) and 12.6 months (95% CI: 9.66–15.54), respectively. No difference in iPFSLM was observed between the WBRT and non-WBRT groups (median 3.9 vs. 2.8 months; HR = 0.506, p = 0.052). The median OSLM was 13.6 months in the WBRT group, compared with 5.7 months in the non-WBRT group (HR = 0.454, p = 0.022). Multivariate analyses of OSLM showed that KPS ≥ 80 at the time of LM diagnosis (HR = 0.428, 95% CI: 0.19–0.94; p = 0.034) and the administration of EGFR-TKIs (HR = 0.258, 95% CI: 0.11–0.58; p = 0.001) were independent predictors of survival, but WBRT (HR = 0.49, 95% CI: 0.24–1.01; p = 0.54) was not. Toxicities associated with WBRT or other treatment were rare.

Conclusion
For EGFR-mutated NSCLC patients with LM, WBRT did not improve intracranial treatment response and survival statistically.

Published: September 2019

Abstract

Background
There are no published studies of the influence of geometry of the scapula on the postoperative recovery of rotator cuff injuries. Our aim was to explore the relationship between the critical shoulder angle (CSA), acromion index (AI), glenoid inclination (GI), and postoperative repair outcomes in shoulder joints after arthroscopic supraspinatus tendon repair.

Methods
Sixty two patients suffering a supraspinatus tear were analyzed retrospectively following failure of conservative treatment and subsequent shoulder arthroscopy in our hospital. Standard anterior and posterior X-rays of the injured shoulder had been performed prior to surgery, with follow ups for at least 2 years (24–43 months). Magnetic resonance imaging (MRI) was performed 2 years after surgery to assess repair of the supraspinatus tendon. Patients were divided into either the intact or re-tear group, according to the MRI results. In addition, assessments using the Constant Shoulder Score (CSS), the American Shoulder and Elbow Surgeon (ASES) Shoulder Assessment Form, the University of California at Los Angeles (UCLA) score and visual analog scale (VAS) score were performed to establish shoulder function at the 2-year evaluation for each patient.

Results
The mean CSA of all patients was 35.79° ± 3.59°, mean AI was 0.72 ± 0.05, and mean GI was 15.87° ± 3.62°. The CSA, AI, and GI in the intact group were statistically significantly different than the re-tear group (p < 0.05). There was no correlation between the magnitude of the CSA, AI, or GI and any shoulder function score (p > 0.05).

Conclusions
The geometry of the scapula had no significant effect on the recovery of postoperative function of patients with rotator cuff injury, but the value of the CSA, AI, and GI affected the risk of rotator cuff re-tear.

Abstract

Background
Mitral valve disease is the most common heart valve disease worldwide. Heart valve operation is the predominant treatment strategy for heart valve disease. This study analyzed the death risk from heart valve disease with respect to the frequency of heart valve operation and other operations in patients with mitral valve disease.

Materials and methods
We conducted a retrospective nationwide population-based case–control study using a claims dataset from Taiwan’s National Health Insurance Research Database. The case and control groups enrolled mitral valve disease patients from 2002 to 2013 who had either underwent an heart valve operation procedure or not, respectively. Conditional logistic regression was estimated the odds ratios (ORs) associated with various risk factors for heart valve operation-related death, including other operations and comorbidities.

Results
A total of 25,964 patients with mitral valve disease were recruited for the study and divided into heart valve operation (600 patients) and non-heart valve operation (25,364 patients) groups. After matching, a total of 1800 non-heart valve operation patients were selected for final analysis. Heart valve operation was associated with decreased risk of death (adjusted OR [aOR] 0.439), but operations related to other cardiovascular disease (CVD, aOR 3.691), respiratory conditions (aOR 3.210), and the urinary system (aOR 1.925) were associated with increased risk of death for patients with mitral valve disease. Patients with mitral valve disease and diabetes (aOR 1.505), chronic kidney disease (CKD, aOR 3.760), or emphysema (aOR 2.623) also had a higher risk of death. Patients who underwent more heart valve operations had a lower risk of death from mitral valve disease, but patients who underwent more other operations had a higher risk of death from mitral valve disease.

Conclusions
The death risk for patients with mitral valve disease patients could be lowered by more frequently performing heart valve operations. However, the risk of death is increased for patients with mitral valve disease who more frequently undergo other operations, chiefly those for other CVD system, respiratory conditions, and urinary system, or have comorbidities such as diabetes, chronic kidney disease, and emphysema.

Abstract

Background
Men with the hereditary peroxisomal disorder X-linked adrenoleukodystrophy (ALD) are at risk of developing inflammatory demyelinating lesions in the brain. In the absence of inflammatory (post-contrast enhancing) lesions on MRI cognitive function is considered spared, but some form of cognitive dysfunction may nevertheless be present. The aim of this cross-sectional study was to characterize cognitive functioning of ALD men with no or minimal MRI abnormalities, which will define cognitive functioning in this category of patients.

Methods
A neuropsychological battery covering a broad range of cognitive domains, including language, verbal and non-verbal memory, visuoconstruction, executive functioning, and psychomotor speed, was used. Means and proportions of borderline and impaired T scores ≤36 were compared to the standardized norm group and a qualitative case-by-case analysis was performed for participants with T scores ≤36 within ≥2 domains. Patients with MRI abnormalities that were extensive (Loes score > 3) or showed enhancement post-contrast were excluded.

Results
Thirty-three men participated (median age 44 years, range 19–71). Mean performance on verbal fluency was poorer in patients (45.70 ± 8.85 patients vs. 50 ± 10 standardized norm group, p = 0.009), as was the percentage of borderline and impaired scores on visuoconstruction (Beery VMI: 19% patients vs. 8% standardized norm group, p = 0.02; RCFT copy: 81% patients vs. 2% standardized norm group, p < 0.0005) and mental reaction time during a complex decision task (18% patients vs. 8% standardized norm group, p = 0.055). Moreover, 9/33 (27.3%) patients had T scores ≤36 within ≥2 domains.

Conclusions
Given the heterogeneous pattern of mostly borderline scores cognitive functioning seems not impaired in the vast majority of adult ALD males with no or minimal MRI abnormalities. However, borderline to impaired cognitive dysfunction was present in 27.3%, with the majority being borderline scores. Longitudinal studies will have to determine if this reflects early cerebral disease under the detection limit of MRI.
Australian R U OK?Day campaign: improving helping beliefs, intentions and behaviours
Authors: Ross Anna M. , Bassilios Bridget 
Published: September 2019

Abstract

Background
Suicide is a major public health concern and has been recognised as a public health priority. R U OK?Day aims to prevent suicide by encouraging and empowering Australians to reach out to friends and family who might be experiencing personal difficulties. This study aims to update the evaluation of the public awareness campaign ‘R U OK?Day’ that was conducted using 2014 data.

Methods
Data from 2013 participants were collected via an online survey following the R U OK?Day campaign implemented in 2017. Outcome measures included campaign awareness and participation, past 12-month help-seeking, helping beliefs, helping intentions and helping behaviours. Data were analysed using z-tests, Chi square and regression analyses in SPSS.

Results
Both campaign awareness and participation have increased since 2014, from 66% and 19% to 78% and 32%. Campaign exposure was associated with stronger beliefs in the importance and the ease of asking “Are you okay?”, and increased the likelihood of intentions to use recommended helping actions by two to three times compared to those not exposed to the campaign. Participants who were exposed to the R U OK?Day campaign were up to six times more likely to reach out to someone who might be experiencing personal difficulties compared to those not exposed to the campaign. Interestingly, those who had sought help from a mental health professional in the past 12 months were more likely to be aware of, and participate in, the campaign, suggesting people experiencing mental health issues recognise the value of seeking—and giving—social support.

Conclusions
The R U OK?Day campaign continues to be relevant and effective in spreading key messages about the importance of reaching out to others and empowering members of the community to have conversations about life problems. The campaign’s impact is increasing over time through increased campaign awareness and participation, and improving helping beliefs, intentions and behaviours. Ongoing monitoring and evaluation of the campaign’s impact is vital and may inform potential changes needed to further enhance its impact.
