Violence and Health Promotion Among First Nations, Métis, and Inuit Women: A Systematic Review of Qualitative Research

Indigenous women experience a disproportionate burden of intimate partner violence (IPV) compared to other women in post-colonial countries such as Canada. Intersections between IPV and other forms of structural violence including racism and gender-based discrimination create a dangerous milieu where ‘help seeking’ may be deterred and poor health outcomes occur. The aim of this review was to explore the perspectives of First Nations, Métis and Inuit (FNMI) women living in Canada about how violence influenced their health and wellbeing. This systematic review of qualitative research used thematic analysis to produce a configurative synthesis. A comprehensive search of electronic databases was conducted. Two reviewers screened studies for relevance and congruence with eligibility criteria. Sixteen studies were included in the review. Four themes with subthemes emerged: 1) ruptured connections between family and home, 2) that emptiness… my spirit being removed, 3) seeking help and being unheard, and 4) a core no one can touch. Together these themes form complex pathways that influenced health among women exposed to violence. Findings from this review highlight the need for collaboration with FNMI women and their communities to prevent IPV and ensure access to trauma and violence informed care (TVIC). The strength and resiliency of FNMI women is fundamental to healing from violence. Working with FNMI women and their communities to build effective interventions and promote culturally meaningful care will be important directions for researchers and policy makers.
Quantitative Eye Gaze and Movement Differences in Visuomotor Adaptations to Varying Task Demands Among Upper-Extremity Prosthesis Users

Key Points Question Is task selection a factor in visuomotor adaptation strategies and therefore a complication in measuring outcomes for users of upper-extremity prostheses? Findings In this cross-sectional study of 8 prosthesis users and 16 participants with normal arm function, between tasks, prosthesis users changed their visuomotor compensatory strategies, and these strategies were different from those used by participants with normal arm function when performing the tasks. However, for a given task, prosthesis users demonstrated similar compensations despite varying amputation levels and technology. Meaning This study suggests that prosthesis users have inherently different ways of functioning for object interaction tasks compared with individuals with normal arm function, and compensation strategies appear to vary depending on the task.
Development of Tactile Imaging for Underwater Structural Damage Detection

Underwater structural damage inspection has mainly relied on diver-based visual inspection, and emerging technologies include the use of remotely operated vehicles (ROVs) for improved efficiency. With the goal of performing an autonomous and robotic underwater inspection, a novel Tactile Imaging System for Underwater Inspection (TISUE) is designed, prototyped, and tested in this paper. The system has two major components, including the imaging subsystem and the manipulation subsystem. The novelty lies in the imaging subsystem, which consists of an elastomer-enabled contact-based optical sensor with specifically designed artificial lighting. The completed TISUE system, including optical imaging, data storage, display analytics, and a mechanical support subsystem, is further tested in a laboratory experiment. The experiment demonstrates that high-resolution and high-quality images of structural surface damage can be obtained using tactile ‘touch-and-sense’ imaging, even in a turbid water environment. A deep learning-based damage detection framework is developed and trained. The detection results demonstrate the similar detectability of five damage types in the obtained tactile images to images obtained from regular (land-based) structural inspection.
A review on anti‐tuberculosis peptides: Impact of peptide structure on anti‐tuberculosis activity

Antibiotic resistance is a major public health problem globally. Particularly concerning amongst drug‐resistant human pathogens is Mycobacterium tuberculosis that causes the deadly infectious tuberculosis (TB) disease. Significant issues associated with current treatment options for drug‐resistant TB and the high rate of mortality from the disease makes the development of novel treatment options against this pathogen an urgent need. Antimicrobial peptides are part of innate immunity in all forms of life and could provide a potential solution against drug‐resistant TB. This review is a critical analysis of antimicrobial peptides that are reported to be active against the M tuberculosis complex exclusively. However, activity on non‐TB strains such as Mycobacterium avium and Mycobacterium intracellulare, whenever available, have been included at appropriate sections for these anti‐TB peptides. Natural and synthetic antimicrobial peptides of diverse sequences, along with their chemical structures, are presented, discussed, and correlated to their observed antimycobacterial activities. Critical analyses of the structure allied to the anti‐mycobacterial activity have allowed us to draw important conclusions and ideas for research and development on these promising molecules to realise their full potential. Even though the review is focussed on peptides, we have briefly summarised the structures and potency of the various small molecule drugs that are available and under development, for TB treatment.
Synthesis of Ergosterol Peroxide Conjugates as Mitochondria Targeting Probes for Enhanced Anticancer Activity

Inspired by the significant bioactivity of ergosterol peroxide, we designed and synthesized four fluorescent coumarin and ergosterol peroxide conjugates 8a–d through the combination of ergosterol peroxide with 7-N,N-diethylamino coumarins fluorophore. The cytotoxicity of synthesized conjugates against three human cancer cells (HepG2, SK-Hep1, and MCF-7) was evaluated. The results of fluorescent imaging showed that the synthesized conjugates 8a–d localized and enriched mainly in mitochondria, leading to significantly enhanced cytotoxicity over ergosterol peroxide. Furthermore, the results of biological functions of 8d showed that it could suppress cell colony formation, invasion, and migration; induce G2/M phase arrest of HepG2 cells, and increase the intracellular ROS level.
Integral Curve Clustering and Simplification for Flow Visualization: A Comparative Evaluation

Unsupervised clustering techniques have been widely applied to flow simulation data to alleviate clutter and occlusion in the resulting visualization. However, there is an absence of systematic guidelines for users to evaluate (both quantitatively and visually) the appropriate clustering technique and similarity measures for streamline and pathline curves. In this work, we provide an overview of a number of prevailing curve clustering techniques. We then perform a comprehensive experimental study to qualitatively and quantitatively compare these clustering techniques coupled with popular similarity measures used in the flow visualization literature. Based on our experimental results, we derive empirical guidelines for selecting the appropriate clustering technique and similarity measure given the requirements of the visualization task. We believe our work will inform the task of generating meaningful reduced representations for large-scale flow data and inspire the continuous investigation of a more refined guidance on clustering technique selection.
Molecular Cloning and Functional Identification of a Squalene Synthase Encoding Gene from Alfalfa (Medicago sativa L.)

The quality of alfalfa, a main legume forage worldwide, is of great importance for the dairy industry and is affected by the content of triterpene saponins. These natural terpenoid products of triterpene aglycones are catalyzed by squalene synthase (SQS), a highly conserved enzyme present in eukaryotes. However, there is scare information on alfalfa SQS. Here, an open reading frame (ORF) of SQS was cloned from alfalfa. Sequence analysis showed MsSQS had the same exon/intron composition and shared high homology with its orthologs. Bioinformatic analysis revealed the deduced MsSQS had two transmembrane domains. When transiently expressed, GFP-MsSQS fusion protein was localized on the plasma membrane of onion epidermal cells. Removal of the C-terminal transmembrane domain of MsSQS improved solubility in Escherichia coli. MsSQS was preferably expressed in roots, followed by leaves and stems. MeJA treatment induced MsSQS expression and increased the content of total saponins. Overexpression of MsSQS in alfalfa led to the accumulation of total saponins, suggesting a correlation between MsSQS expression level with saponins content. Therefore, MsSQS is a canonical squalene synthase and contributes to saponin synthesis in alfalfa. This study provides a key candidate gene for genetic manipulation of the synthesis of triterpene saponins, which impact both plant and animal health.
“I do all I can but I still fail them”: Health system barriers to providing Option B+ to pregnant and lactating women in Malawi

Malawi’s Option B+ program is based on a ‘test and treat’ strategy that places all HIV-positive pregnant and lactating women on lifelong antiretroviral therapy. The steep increase in patient load placed severe pressure on a health system that has struggled for decades with inadequate supply of health care workers (HCWs) and poor infrastructure. We set out to explore health system barriers to Option B+ by asking HCWs in Malawi about their experiences treating pregnant and lactating women. We observed and conducted semi-structured interviews (SSIs) with 34 HCWs including nine expert clients (ECs) at 14 health facilities across Malawi, then coded and analyzed the data. We found that HCWs implementing Option B+ are so overburdened in Malawi that it reduces their ability to provide quality care to patients, who receive less counseling than they should, wait longer than is reasonable, and have very little privacy. Interventions that increase the number of HCWs and upgrade infrastructure to protect the privacy of HIV-infected pregnant and lactating women and their husbands could increase retention, but facilities will need to be improved to support men who accompany their partners on clinic visits.
Enabling Self-management of a Chronic Condition through Patient-centered Coaching: A Case of an mHealth Diabetes Prevention Program for Older Adults

ABSTRACT Patient-centered communication (PCC) by healthcare professionals can contribute to enacting and facilitating patients’ self-management of chronic health conditions. This study investigates the emerging patterns of PCC that occur in an mHealth-based diabetes prevention program for older adults. The analysis of user-coach communication data during the 16-week period of the program revealed four PCC strategies employed by coaches: (a) triggering reflections on users’ routinized habits, (b) jointly determining a measurable health goal, (c) facilitating self-evaluations on recent behavior change, and (d) tailoring programs to adapt to users’ lifestyle and health status. To advance these strategies, coaches utilized various mHealth features that helped them (a) engage in data-driven coaching, (b) increase situational awareness of users’ health conditions and routines, (c) provide continuous support to users through regular and spontaneous in-app chats, and (d) foster user autonomy and engagement. The findings extend implications for developing technology-enabled healthcare practice to enhance self-management of chronic illness.
Identification of polyphenolic contents, in vitro evaluation of antioxidant and antidiabetic potentials of a polyherbal formulation-Mehani

Abstract Diabetes has become a global disease that needs an alternative drug treatment with lesser side effects. The present study was aimed to evaluate the antioxidant and antidiabetic activities of soxhlet and microwave assisted extraction of a polyherbal formulation-Mehani using aqueous, hydroalcoholic and hexane solvents. Preliminary investigation shows that the heavy metal contents were within the permissible limits. Comparative antioxidant studies showed that hydroalocoholic soxhlet (HAS) and microwave (HAM) extracts possessed highest activity as assessed through DPPH assay (93.8 ± 0.04%, 94.85 ± 0.04%), H2O2 assay (88.7 ± 0.9%, 87.2 ± 1.4%), reducing power assay (absorbance-1.61 ± 0.12, 2.08 ± 0.03) and nitric oxide scavenging activity (51.1 ± 0.9%, 56.5 ± 0.18%) at 500 µg/mL concentration. HAS and HAM also exhibited 80.3 ± 1.12% and 85.3 ± 1.86% of α-amylase inhibitory activity and 78.7 ± 0.15% and 80.0 ± 0.63% of glucosidase inhibitory activity. HPLC analysis in both the extracts reveals the presence of eight polyphenols with gallic acid being the predominant compound; these might be responsible for the highest activities. GRAPHICAL ABSTRACT
FLAMSA-RIC for Stem Cell Transplantation in Patients with Acute Myeloid Leukemia and Myelodysplastic Syndromes: A Systematic Review and Meta-Analysis

Reduced-intensity conditioning (RIC) regimens are established options for hematopoietic stem cell transplantation (HSCT) for patients with acute myeloid leukemia (AML) and myelodysplastic syndrome (MDS). However, the efficacy of RIC regimens for patients with high-risk disease is limited. The addition of a fludarabine, amsacrine, and cytarabine (FLAMSA)-sequential conditioning regimen was introduced for patients with high-risk MDS and AML to combine a high anti-leukemic activity with the advantages of RIC. The current systematic literature review and meta-analysis was conducted with the aim of identifying all cohort studies of patients with AML and/or MDS who received FLAMSA-RIC to determine its efficacy and toxicity. Out of 3044 retrieved articles, 12 published studies with 2395 overall patients (18.1–76.0 years; 96.8% AML and 3.2% MDS; follow-up duration of 0.7–145 months; 50.3% had active AML disease before HSCT) met the eligibility criteria and were included in the meta-analysis. In the pooled analysis, the 1- and 3-year overall survival (OS) rates were 59.6% (95% confidence interval (CI), 47.9–70.2%) and 40.2% (95% CI, 28.0–53.7%), respectively. The pooled 3-year OS rate of the patients who achieved CR1 or CR2 prior to HSCT was 60.1% (95% CI, 55.1–64.8%) and the percentage of those with relapse or refractory disease was 27.8% (95% CI, 23.3–32.8%). The pooled 3-year leukemia-free survival (LFS) rate was 39.3% (95% CI, 26.4–53.9%). Approximately 29% of the patients suffered from grades 2–4 acute graft-versus-host disease (GVHD), while 35.6% had chronic GVHD. The pooled 1- and 3-year non-relapse mortality (NRM) rates were 17.9% (95% CI, 16.1–19.8%) and 21.1% (95% CI, 18.8–23.7%), respectively. Our data indicates that the FLAMSA-RIC regimen is an effective and well-tolerated regimen for HSCT in patients with high-risk AML and MDS.
Comparison of Tacrolimus Starting Doses Based on CYP3A5 Phenotype or Genotype in Kidney Transplant Recipients

Background: Selection of expected phenotypes (ie, expressers/non-expressers) is currently used in CYP3A5*3 genotype-based tacrolimus dosing. The authors assessed whether a dosing regimen based on the 3 CYP3A5 genotypes may reduce the occurrence of inadequate exposure. Methods: Tacrolimus whole blood trough levels (C 0) were retrieved from a retrospective cohort of 100 kidney transplant recipients treated with a starting dose of 0.15 (non-expressers) or 0.30 (expressers) mg/kg/d. The authors evaluated the occurrence of overexposures (12 < C 0 < 20 ng/mL) or toxic concentrations (C 0 ≥ 20 ng/mL). These results were used to set up a new strategy based on the 3 distinct CYP3A5 genotypes, which relevance was evaluated in a prospective cohort of 107 patients. Results: In the retrospective cohort, non-expressers exhibited frequent overexposure (63.6%) or toxic C 0 (20.8%). Among expressers, none of the homozygous *1 carriers exhibited overexposure contrary to 25% of the heterozygotes. Based on these results, new tacrolimus starting doses were set at 0.10, 0.20, and 0.30 mg/kg/d for CYP3A5*3/*3, CYP3A5*1/*3, and CYP3A5*1/*1 genotypes, respectively. Tacrolimus overexposure was reduced in the CYP3A5*3/*3 group (63.6% vs 40%, P = .0038). None of the heterozygous patients exhibited toxic tacrolimus C 0. Clinical outcomes were not different between the 2 periods, whatever the genotype. Our results indicate that the best tacrolimus exposure was obtained for doses of 0.10, 0.20, and 0.20 mg/kg/d for CYP3A5*3/3, CYP3A5*1/*3, and CYP3A5*1/*1, respectively. Conclusions: Our results confirm that selecting tacrolimus dosing regimen according to the expected phenotype is appropriate, but that lower than currently recommended doses may be preferable.
No evidence of inbreeding depression in fast declining herds of migratory caribou

Identifying inbreeding depression early in small and declining populations is essential for management and conservation decisions. Correlations between heterozygosity and fitness (HFCs) provide a way to identify inbreeding depression without prior knowledge of kinship among individuals. In Northern Quebec and Labrador, the size of two herds of migratory caribou (Rivière‐George, RG and Rivière‐aux‐Feuilles, RAF) has declined by one to two orders of magnitude in the last three decades. This raises the question of a possible increase in inbreeding depression originating from, and possibly contributing to, the demographic decline in those populations. Here, we tested for the association of genomic inbreeding indices (estimated with 22,073 SNPs) with body mass and survival in 400 caribou sampled in RG and RAF herds between 1996 and 2016. We found no association of individual heterozygosity or inbreeding coefficient with body mass or annual survival. Furthermore, those genomic inbreeding indices remained stable over the period monitored. These results suggest that the rapid and intense demographic decline of the herds did not cause inbreeding depression in those populations. Although we found no evidence for HFCs, if demographic decline continues, it is possible that such inbreeding depression would be triggered.
Cognitive Dysfunction and Its Predictors in Adult Patients With Cancer Receiving Chemotherapy: A Cross-Sectional Correlational Study.

BACKGROUND Chemotherapy-related cognitive dysfunction, one of the most frequently reported symptoms in patients with cancer, has a negative impact on the daily lives of patients. No research has examined cognitive dysfunction and its potential predictors in adult patients with cancer receiving chemotherapy in Saudi Arabia. PURPOSE The purpose of this study was to examine the sociodemographic, clinical, and psychological factors associated with cognitive dysfunction in adult patients with cancer receiving chemotherapy. METHODS A cross-sectional correlational study was carried out with a convenience sample of 100 adult patients with cancer receiving chemotherapy at a university teaching hospital in Saudi Arabia. The Montreal Cognitive Assessment, the Hospital Anxiety and Depression Scale, and sociodemographic and clinical surveys were completed by participants. Descriptive statistics and linear regression were used to analyze the data. RESULTS The data showed that the participants experienced moderate-to-severe cognitive dysfunction. Participants performed poorly in the divided attention and memory cognitive domains. Age, educational level, and depression factors were found to be significant predictors of cognitive dysfunction. CONCLUSIONS/IMPLICATIONS FOR PRACTICE Cognitive dysfunction is commonly seen in patients with cancer receiving chemotherapy. Chemotherapy, age, and psychological factors increase susceptibility to cognitive dysfunction in adult patients with cancer. Oncology nurses should be aware that patients with cancer may be extremely vulnerable to cognitive dysfunction. Furthermore, age and psychological factors must be considered when developing symptom management and supportive care intervention programs to reduce the incidence of negative cognitive outcomes in this population.
Bacillus thuringiensis Cry5B is active against Strongyloides stercoralis in vitro.

Strongyloidiasis, caused by Strongyloides stercoralis infection, is an important neglected tropical disease that causes significant public health problems in the tropics and subtropics. The disease can persist in hosts for decades and may be life-threatening because of hyperinfection and dissemination. Ivermectin (mostly) and albendazole are the most common anthelmintics used for treatment. Albendazole is suboptimal for this parasite, and although ivermectin is quite effective in immunocompromised patients, a multiple-course regimen is required. Furthermore, reliance on a single drug class for treating intestinal nematodes is a recipe for future failure. Therefore, it is important to discover new anthelmintics to treat or prevent human strongyloidiasis. One promising candidate is the Bacillus thuringiensis crystal protein Cry5B. Cry5B is highly potent against parasitic nematodes, for example, hookworms and Ascaris suum. Here, we investigated the potential of Cry5B against S. stercoralis. Multiple stages of S. stercoralis, including the first larval stage (L1s), infective stage (iL3s), free-living adult stage, and parasitic female stage, were all susceptible to Cry5B as indicated by impairment of motility and decreased viability in vitro. In summary, Cry5B demonstrated strong potential as an effective anthelmintic for treatment and transmission control of human strongyloidiasis, justifying further experiments to investigate in vivo therapeutic efficacy.
Population Pharmacokinetics of Glecaprevir/Pibrentasvir in HCV‐infected Japanese Subjects in Phase 3 CERTAIN‐1 and CERTAIN‐2 Trials

Glecaprevir (GLE)/pibrentasvir (PIB) 300 mg/120 mg once daily (Mavyret/Maviret) is an all‐oral, pangenotypic, interferon‐ and ribavirin‐free combination regimen approved for the treatment of chronic hepatitis C virus (HCV) infection. The objective of the current analyses was to characterize the pharmacokinetics (PK) of GLE/PIB in HCV‐infected Japanese patients. Data from 332 subjects enrolled in 2 Japan phase 3 trials, CERTAIN‐1 and CERTAIN‐2, were used in the analyses. Pharmacokinetics of GLE/PIB were characterized using a nonlinear mixed‐effects modeling. The analyses evaluated the impact of covariates (concomitant medications and demographic and clinical covariates such as renal impairment, effect of cirrhotic status) on GLE/PIB PK. GLE and PIB PK were described by 1‐ and 2‐compartment models, respectively. Presence of cirrhosis, age, and body weight were identified as significant covariates on GLE/PIB PK. A trend toward higher GLE and PIB exposures in older patients and higher PIB exposures in heavier patients was observed; however, these increases were not considered clinically meaningful. GLE and PIB exposures were higher in HCV‐infected subjects with cirrhosis (Child‐Pugh A; GLE area under the plasma concentration–time curve was 160% higher, and PIB area under the plasma concentration–time curve was 21% higher) compared to subjects without cirrhosis. Renal function (including subjects with end‐stage renal disease with dialysis) had no impact on GLE or PIB exposures. The GLE/PIB dose was well tolerated in the Japanese population, and no dose adjustment is needed for the evaluated intrinsic and extrinsic factors.
