Abstract
Background Computed tomography (CT) is still fairly expensive in Cameroon and is mainly accessed through out-of-pocket (OOP) payments. Its introduction to peripheral health facilities in communities where many live below the poverty line and do not have financial risk protection is a laudable effort though current price listings suggest a mismatch with the purchasing power of potential users. Risk of financial hardship after CT use is an expected reality and we sought to determine predisposing factors and elaborate on how users adapt and cope. Methods We carried out a sequential explanatory mixed methods study with a quantitative hospital-based survey of CT users followed by an in-depth interview of some purposively selected participants who reported risk of financial hardship after CT use. Data was summarized using frequencies, percentages and 95% confidence intervals. Logistic regression was used in multivariable analysis to determine predictors of risk of financial hardship. Themes emerging from the in-depth interviews were categorized. Quantitative and qualitative data were integrated. Results A total of 372 participants were surveyed with a male to female sex ratio of 1:1.2. The mean age (standard deviation) was 52(17) years. CT scans of the head and facial bones accounted for 63% (95%CI: 59%-68%) and the top three indications were suspected stroke (27% [95%CI: 22%-32%]), trauma (14% [95%CI: 10%-18%]) and persistent headaches with blurred vision (14% [95%CI: 10%-18%]). Seventy-two percent (95%CI: 67%-76%) of respondents declared being at risk of financial hardship after CT use and predictors in the multivariable analysis were low socioeconomic status (aOR: 0.19 [95%CI: 0.10-0.38]; p<0.001) and not having any form of financial risk protection (aOR: 3.59 [95%CI: 1.31-9.85]; p=0.013). Coping strategies included relying on family members and friends for financial assistance, lobbying hospital administration, social services and healthcare staff for a reduction of the direct cost, and borrowing of money. Conclusion The risk of financial hardship is a real threat to CT utilization and some users resort to different practices to minimize the burden of OOP payments. Opportunities to improve CT affordability should be enhanced to reduce this burden and the negative consequences of the coping strategies.

Abstract
Background Studies document e-health as having potential to improve quality of healthcare services, resulting in both developed and developing countries demonstrating continued interest in e-health uptake and use. e-Health implementations are not always successful as high failure rates have been reported in both developed and developing countries. These failures are often a result of lack of e-health readiness. e-Health readiness has been defined as the preparedness of healthcare institutions or communities for the anticipated change brought by programs related to information and communication technologies. As such it is critical to conduct an e-health readiness assessment prior to implementation of e-health innovations so as to reduce chances of project failure. Noting the absence of an adequate e-health readiness assessment framework (eHRAF) suitable for use in developing countries, the authors conceptualised, designed, and created a developing country specific eHRAF to aid in e-health policy planning. The aim of this study was to validate the developed eHRAF and to determine if it required further refinement before empirical testing. Methods Published options for a framework validation process were adopted, and fifteen globally located e-health experts engaged. Botswana experts were engaged using saturation sampling, while international experts were purposively selected. Responses were collated in an Excel spreadsheet, and NVivo 11 software used to aid thematic analysis of the open ended questions. Results Analysis of responses showed overall support for the content and format of the proposed eHRAF. Equivocal responses to some open ended questions were recorded, most of which suggested modifications to terms within the framework. One expert from the developed world had alternate views. Conclusions The proposed eHRAF provides guidance for e-health policy development and planning by identifying, in an evidence based manner, the major areas to be considered when preparing for an e-health readiness assessment in the context of developing countries.

Abstract
Background The relationship between intraoperative low bispectral index (BIS) values and poor clinical outcomes has been controversial. Intraoperative hypotension is associated with postoperative complication. The purpose of this study was to investigate the influence of intraoperative low BIS values and hypotension on postoperative mortality in patients undergoing major abdominal surgery. Methods This retrospective study analyzed 1,862 cases of general anesthesia. We collected the cumulative time of BIS values below 20 and 40 as well as electroencephalographic suppression and documented the incidences in which these states were maintained for at least 5 minutes. Durations of intraoperative mean arterial pressures (MAP) less than 50 mmHg were also recorded. Multivariable logistic regression was used to evaluate the association between suspected risk factors and postoperative mortality. Results Ninety-day mortality and 180-day mortality were 1.5% and 3.2% respectively. The cumulative time in minutes for BIS values falling below 40 coupled with MAP falling below 50 mmHg was associated with 90-day mortality (odds ratio, 1.26; 95% confidence interval, 1.04-1.53; P = .019). We found no association between BIS related values and 180-day mortality. Conclusions Delicate adjustment of anesthetic depth is important to avoid excessive brain suppression and hypotension, which could be associated with postoperative mortality.

Abstract
Background: Pre-wetted disinfectant wipes are increasingly being used in healthcare facilities to help address the risk of healthcare associated infections (HAI). However, HAIs are still a major problem in the US with Clostridioides difficile being the most common cause, leading to approximately 12,800 deaths annually in the US. An underexplored risk when using disinfectant wipes is that they may cross-contaminate uncontaminated surfaces during the wiping process. The objective of this study was to determine the cross-contamination risk that pre-wetted disinfectant towelettes may pose when challenged with C. difficile spores. We hypothesized that although the tested disinfectant wipes had no sporicidal claims, they will reduce spore loads. We also hypothesized that hydrogen peroxide disinfectant towelettes would present a lower cross-contamination risk than quaternary ammonium products. Methods: We evaluated the risk of cross-contamination when disinfectant wipes are challenged with C. difficile ATCC 43598 spores on Formica surfaces. A disinfectant wipe was used to wipe a Formica sheet inoculated with C. difficile. After the wiping process, we determined log10 CFU on previously uncontaminated pre-determined distances from the inoculation point and on the used wipes. Results: We found that the disinfectant wipes transferred C. difficile spores from inoculated surfaces to previously uncontaminated surfaces. We also found that wipes physically removed C. difficile spores and that hydrogen peroxide disinfectants were more sporicidal than the quaternary ammonium disinfectants. Conclusion: Regardless of the product type, all disinfectant wipes had some sporicidal effect but transferred C. difficile spores from contaminated to otherwise previously uncontaminated surfaces. Disinfectant wipes retain C. difficile spores during and after the wiping process.

Abstract
Background The impact of social support on diabetes management and health outcomes has been investigated comprehensively, with recent studies examining social support delivered via digital technologies. This paper argues that social support has an impact on the use of diabetes technologies. Specifically, we postulate differences between the impact of healthcare professional versus non-professional (family/friends) support on mobile app use for diabetes self-management.Methods This research employed a triangulation of methods including exploratory semi-structured face-to-face interviews (N= 21, Study 1) and an online survey (N= 65, Study 2) with adult type 1 and type 2 diabetes patients. Thematic analysis (Study 1) was used to explore the relevance of social support (by professionals versus non-professionals) for diabetes app use. Binary logistic regression (Study 2) was applied to compare healthcare decision-making, healthcare-patient communication, and the support by the personal patient network as predictors of diabetes app use, complemented by other predictors from self-management and technology adoption theory.Results The interviews (Study 1) demonstrated that (technology-supported) shared decision-making and supportive communication by healthcare professionals depended on the medical specialty of attending physicians. The personal patient network was perceived as either facilitating or hindering the use of mHealth for self-management. Binary logistic regression (Study 2) showed that the specialty of the physician significantly predicted the use of diabetes apps, with supervision by diabetes specialists increasing the likelihood of app use (as opposed to general practitioners). In addition, specialist care positively related to a higher chance of shared decision-making and better physician-patient communication. The support by the personal patient network predicted diabetes app use in the opposite direction, with lower family/friend support increasing the likelihood of app use.Conclusion The results emphasize the relevance of support by healthcare professionals and by the patient network for diabetes app use and disclose differences from existing literature. In particular, we found that the use of diabetes apps may increase in the absence of social support by family or friends (e.g., compensation for lack of support), and that use of diabetes apps may decrease when support is high (e.g., no perceived need to use technology). Implications for practice are discussed.

Abstract
Background: Human exposure to high doses of radiation resulting in acute radiation syndrome and death could rapidly escalate to a mass casualty catastrophe in the event of nuclear accidents or terrorism. The primary reason is that there is presently no effective treatment option, especially for radiation-induced gastrointestinal syndrome. This syndrome results from disruption of mucosal barrier integrity leading to severe dehydration, blood loss and sepsis. In this study, we tested whether small extracellular vesicles/exosomes derived from mesenchymal stromal cells (MSC) could reduce radiation-related mucosal barrier damage and reduce radiation-induced animal mortality. Methods: Human MSC-derived small extracellular vesicles/exosomes were intravenously administered to NUDE mice, 3, 24 and 48 hours after lethal whole-body irradiation (10 Gy). Integrity of the small intestine epithelial barrier was assessed by morphologic analysis, immunostaining for tight junction protein (claudin-3) and in vivo permeability to 4 kDa FITC-labeled dextran. Renewal of small intestinal epithelium was determined by the quantification of epithelial cell apoptosis (TUNEL staining) and proliferation (Ki67 immunostaining). Statistical analyses were performed using one-way ANOVA followed by a Tukey test. Statistical analyses of mouse survival were performed using the methods of Kaplan-Meier and Cox. Results: We demonstrated that MSC-derived small extracellular vesicles/exosomes treatment reduced by 85% the instantaneous mortality risk in mice subjected to 10 Gy whole-body irradiation and thus increased their survival time. This effect could be attributed to the efficacy of MSC-derived small extracellular vesicles/exosomes in reducing mucosal barrier disruption. We showed that MSC-derived small extracellular vesicles/exosomes improved renewal of the small intestinal epithelium by stimulating proliferation and inhibiting apoptosis of the epithelial crypt cells. MSC-derived small extracellular vesicles/exosomes also reduced radiation-induced mucosal permeability as evidenced by the preservation of claudin-3 immunostaining at the tight junctions of the epithelium. Conclusions: MSC-derived small extracellular vesicles/exosomes promote epithelial repair and regeneration and preserve structural integrity of the intestinal epithelium in mice exposed to radiation-induced gastrointestinal toxicity. Our results suggest that the administration of MSC-derived small extracellular vesicles/exosomes could be a treatment modality to limit acute radiation syndrome.

Abstract
Background: Increasing evidence has revealed that long non-coding RNAs (lncRNAs) exert critical roles in biological mineralization. As a critical process for dentin formation, odontoblastic differentiation is regulated by complex signaling networks. The present study aimed to investigate the biological role and regulatory mechanisms of lncRNA-H19 (H19) in regulating the odontoblastic differentiation of human dental pulp stem cells (hDPSCs). Methods: We performed lncRNA microarray assay to reveal the expression patterns of lncRNAs involved in odontoblastic differentiation. H19 was identified and verified by qRT-PCR. The gain- and loss-of-function studies were performed to investigate the biological role of H19 in regulating odontoblastic differentiation of hDPSCs in vitro and in vivo. Odontoblastic differentiation was evaluated through qRT-PCR, Western blot and Alizarin Red S staining. Bioinformatics analysis identified that H19 could directly interact with miR-140-5p, which was further verified by luciferase reporter assay. After overexpression of miR-140-5p in hDPSCs, odontoblastic differentiation was determined. Moreover, the potential target genes of miR-140-5p were investigated and the biological functions of BMP-2 and FGF9 in hDPSCs were verified. Co-transfection experiments were conducted to validate miR-140-5p was involved in H19-mediated odontoblastic differentiation in hDPSCs.Results: The expression of H19 was significantly up-regulated in hDPSCs undergoing odontoblastic differentiation. Overexpression of H19 stimulated odontoblastic differentiation in vitro and in vivo, whereas down-regulation of H19 revealed the opposite effect. H19 binds directly to miR-140-5p and overexpression of miR-140-5p inhibited odontoblastic differentiation of hDPSCs. H19 acted as a miR-140-5p sponge, resulting in regulated the expression of BMP-2 and FGF9. Overexpression of H19 abrogated the inhibitory effect of miR-140-5p on odontoblastic differentiation.Conclusion: Our data revealed that H19 plays a positive regulatory role in odontoblastic differentiation of hDPSCs through miR-140-5p/BMP-2/FGF9 axis, suggesting that H19 may be a stimulatory regulator of odontogenesis.

Abstract
Background: It is known that dietary consumption of ω-3 fatty acids is correlated with a reduced incidence of cardiovascular events. Here, we investigated the effect of dietary ω-3 fatty acids on atrial fibrillation (AF) vulnerability in a canine model of AF and explored the related mechanisms. Methods: 24 male beagle dogs (weight, 8-10 kg) were randomly divided into four groups: (a) sham-operated group (normal chow), (b) AF group ( AF with normal chow), (c) AF+FO (AF and chow supplemented with fish oil (FO, 0.6 g ω-3 PUFA/kg/day)), (d) FO (chow supplemented with FO). Daily oral administration FO was initiated 1 week before surgery and continued throughout the study period. Results: Dietary FO significantly reversed atrial electric remodeling post rapid atria pacing (RAP). FO treatment also attenuated the elevated levels of biomakers for ER stress (all P<0.05 vs. AF). RAP-induced upregulation of inflammation factors IL-1β, IL-6, TNF-α in LA were significantly attenuated by FO treatment (all p<0.05 vs. AF). In addition, Masson staining revealed increased interstitial fibrosis in LA was significantly reduced in AF+FO group as compared to AF group (P<0.01). FO treatment also alleviated RAP-induced myocardial apoptosis (p<0.05). Conclusions: Dietary ω-3 fatty acids reduced RAP-induced AF vulnerability, possibly via attenuating myocardial ER stress and inflammation in this canine model of AF.

Abstract
Introduction: Surgical Site Infections (SSIs) are infections that occur at or near the surgical incision within 30 days of the surgery. SSIs are the commonest form of hospital acquired infections in sub Saharan Africa with estimates between 15%-45%. Cesarean section (CS) is the single most important risk factor for postpartum infections, carrying a 5 to 20-fold increase in the risk of developing sepsis, with an even higher risk when the operation is an emergency. In sub Saharan Africa, the leading cause of maternal mortality is puerperal sepsis. There is a need for simple interventions that can reduce this burden of SSI in the limited resource settings. Therefore, the purpose of this study was to measure the effectiveness of chloroxylenol in reducing the incidence of post Cesarean section surgical site infections at Mbarara Regional Referral Hospital (MRRH).Methods: We conducted a single blinded randomized controlled trial at MRRH maternity ward in which women due for CS were randomized into either control or intervention arms. The intervention was a complete body bath with chloroxylenol antiseptic soap before the operation, while the control arm study participants received a standard pre-operative preparation procedures according to the existing ward protocol. All participants were followed up for 30 days and assessed using a standard SSI screening tool. Results: Ninety-six women were randomized, and 48 were assigned to either arm. The overall incidence of SSI was 30.21%. The incidence of SSI was significantly lower in the intervention compared to the control arm, at 6.25% in the intervention arm versus 54.17% in the control arm (p value<0.001). Chloroxylenol bath was protective of SSI with a 90% risk reduction for SSI (95% confidence interval of 67% – 97%). Conclusion: A preoperative bath with chloroxylenol for pregnant mothers is associated with a significantly lower risk of post Cesarean section surgical site infections. Health facilities with a high burden of post SSI should consider adding this simple and effective intervention to the existing infection prevention measures.

Abstract
Purpose: Ectopic adrenocorticotropic hormone (ACTH)-secreting lung tumours represent the most common cause of ectopic Cushing syndrome (ECS). Pulmonary opportunistic infections are associated with ECS and occasionally difficult to differentiate from tumours by using computed tomography (CT) alone. The aim of the present study was to evaluate the usefulness of 18F-fluorodeoxyglucose (FDG) positron emission tomography/CT (18F-FDG PET/CT) for differentiating ectopic ACTH-secreting lung tumours from tumour-like pulmonary infections in patients with ECS.Methods: We retrospectively reviewed the imaging data for 24 patients with ECS who were suspected to have ACTH-secreting lung tumours and underwent 18F-FDG PET/CT between 2008 and 2019.Results: In total, 18 patients had lung tumours (17 carcinoids and 1 small cell lung cancer) and six had pulmonary infections (cryptococcosis, n = 3; aspergillosis, n = 4; pulmonary abscess, n = 1). The primary source of ECS remained occult in the six patients with pulmonary infections. The maximum standardized uptake value (SUVmax) for pulmonary infections was significantly higher than that for tumours (P = 0.008). Receiver operating characteristic analysis was performed, and it was found that a cut-off SUVmax of 4.95 helped in differentiating lung tumours from infections with 75% sensitivity and 94.4% specificity. In subgroup analysis of 12 typical and five atypical carcinoids, there was no significant between-group difference with respect to SUVmax, the lesion size, the ACTH level, and the prevalence of regional lymph node metastasis.Conclusions: Our findings suggest that pulmonary infections exhibit significantly higher FDG uptake than do ACTH-secreting lung tumours in 18F-FDG PET/CT. Therefore, SUVmax (cut-off 4.95) may be useful for differentiating the two conditions. Typical and atypical ACTH-secreting lung carcinoids may show a similar clinical behaviour and appearance on 18F-FDG PET/CT.
