Experiences and resultant care gaps among women with HIV in Canada: concept mapping the Canadian HIV Women's Sexual and Reproductive Health Cohort Study (CHIWOS) findings.

Objectives: The community-based, longitudinal, Canadian HIV Women's Sexual and Reproductive Health Cohort Study (CHIWOS) explored the experiences of women with HIV in Canada over the past decade. CHIWOS' high-impact publications document significant gaps in the provision of healthcare to women with HIV. We used concept mapping to analyse and present a summary of CHIWOS findings on women's experiences navigating these gaps.

Barriers to and facilitators of effective management of fever episodes in hospitalised Kenyan children with cancer: protocol for convergent mixed methods study.

Introduction: Febrile neutropenia is an oncological emergency in children with cancer, associated with serious infections and complications. In low-resourced settings, death from infections in children with cancer is 20 times higher than in high-resourced treatment settings, thought to be related to delays in antibiotic administration and management. The barriers to effective management of fever episodes in children with cancer have not previously been described.

Development, roll-out and implementation of an antimicrobial resistance training curriculum harmonizes delivery of in-service training to healthcare workers in Kenya.

Background: Antimicrobial resistance (AMR) is an increasingly severe threat to global public health that requires action across different sectors. Selection of appropriate antimicrobials is an urgent challenge due to the emergence of drug resistance. In 2017, Kenya developed an AMR policy and National Action Plan to drive prevention and containment of AMR.

Training pharmacy students to deliver bad news using the SPIKES model.

Background And Purpose: Delivery of bad news or negative health information is a complex skill critical to the provision of patient care. While counseling models with this focus exist within other health care professions, their use in pharmacy education is lacking. The purpose of this study is to assess pharmacy students' ability to deliver bad news with the implementation of a counseling model titled SPIKES (Setting, Perception, Invitation, Knowledge, Emotions with Empathy, and Strategy/Summary).

Assessing Learner Engagement and the Impact on Academic Performance within a Virtual Learning Environment.

Background: The objective of this pilot study was to examine student engagement with weekly self-paced learning materials in a virtual therapeutics course, and how sub-factors in the Motivated Strategies for Learning Questionnaire (MSLQ) may have influenced academic performance.

Methods: Students within a diabetes module of a therapeutics course were provided with weekly asynchronous optional self-directed learning activities. Student submissions, on-time rates, self-reported weekly study time, and exam performance were collected.

Review of Rapid Diagnostic Methods for Detection in the Last Decade (2011-2022).

Introduction: Cholera epidemic poses a global public health threat, heavily impacting the global economy and societies, with Africa and Asia particularly affected due to factors like; inadequate sanitation, contaminated water, and overcrowding. The associated high rates of morbidity and mortality strain productivity and healthcare costs while complicating control measures. Consequently, the World Health Organization's cholera control initiative and the Diarrhoeal Diseases Laboratory Network advocate for rapid responses to outbreaks and continuous environmental surveillance, since traditional cholera detection methods relying on phenotypic fingerprinting, although considered the gold standard, suffer from labour-intensiveness, time-consumption, and skill requirements.

The influence of organic and inorganic nutrient inputs on soil organic carbon functional groups content and maize yields.

Locally available organic inputs to soil, solely or in combination with inorganic fertilizers, are used to reverse declining soil fertility and improve soil organic matter content (SOM) in smallholder farms of most Sub-Saharan Africa (SSA) countries. Soil organic matter characterization can indicate soil organic input, carbon (C) sequestration potential, or even an authentication tool for soil C dynamics in C stocks accounting. This study determined the effects of the long-term application of selected integrated soil fertility management (ISFM) technologies on SOM functional group composition and maize yields.

Women-centred HIV care: a scoping review to understand the current state of service delivery for women living with HIV globally.

Women living with HIV (WLWH) face unique barriers and require specialized, integrated care that focuses on women's specific needs. We conducted a scoping review to examine factors important for a women-centred HIV care (WCHC) approach. We included published peer-reviewed articles which featured WCHC services as their central focus; included study populations of girls and WLWH aged 14 years of age or older; and contributed to the understanding of WCHC for WLWH.

Loss of capillary pericytes and the blood-brain barrier in white matter in poststroke and vascular dementias and Alzheimer's disease.

White matter (WM) disease is associated with disruption of the gliovascular unit, which involves breach of the blood-brain barrier (BBB). We quantified pericytes as components of the gliovascular unit and assessed their status in vascular and other common dementias. Immunohistochemical and immunofluorescent methods were developed to assess the distribution and quantification of pericytes connected to the frontal lobe WM capillaries.

Identification of Glutamic Acid as a Host Marking Pheromone of the African Fruit Fly Species Ceratitis rosa (Diptera: Tephritidae).

Host marking pheromones (HMPs) deposited by female fruit flies deter other females from overexploiting the same fruit for egg laying. Using a bioassay-guided approach, we identified the HMP of the Natal fruit fly species Ceratitis rosa as glutamic acid, 1, from the aqueous fecal matter extract of ovipositing females by liquid chromatography-quadrupole time-of-flight-mass spectrometry (LC-QTOF-MS). Dual choice oviposition assays showed that both the fecal matter extract and 1 significantly reduced oviposition responses in conspecific females of C.

Identification of the Ubiquitous Antioxidant Tripeptide Glutathione as a Fruit Fly Semiochemical.

Many insects mark their oviposition sites with a host marking pheromone (HMP) to deter other females from overexploiting these sites. Previous studies have identified and used HMPs to manage certain fruit fly species; however, few are known for African indigenous fruit flies. The HMP of the African fruit fly, Ceratitis cosyra, was identified as the ubiquitous plant and animal antioxidant tripeptide, glutathione (GSH).

Frontal white matter hyperintensities, clasmatodendrosis and gliovascular abnormalities in ageing and post-stroke dementia.

White matter hyperintensities as seen on brain T2-weighted magnetic resonance imaging are associated with varying degrees of cognitive dysfunction in stroke, cerebral small vessel disease and dementia. The pathophysiological mechanisms within the white matter accounting for cognitive dysfunction remain unclear. With the hypothesis that gliovascular interactions are impaired in subjects with high burdens of white matter hyperintensities, we performed clinicopathological studies in post-stroke survivors, who had exhibited greater frontal white matter hyperintensities volumes that predicted shorter time to dementia onset.

A major host plant volatile, 1-octen-3-ol, contributes to mating in the legume pod borer, Maruca vitrata (Fabricius) (Lepidoptera: Crambidae).

Previous studies on the legume pod borer, Maruca vitrata Fabricius (Lepidoptera: Crambidae), a serious pest of cowpea, Vigna unguiculata (L.) Walp. (Fabales: Fabaceae), in sub-Saharan Africa have focused on sex pheromones, but the role of the host plant on sexual behavior has not been explored.

Potential of the Desert Locust Schistocerca gregaria (Orthoptera: Acrididae) as an Unconventional Source of Dietary and Therapeutic Sterols.

Insects are increasingly being recognized not only as a source of food to feed the ever growing world population but also as potential sources of new products and therapeutic agents, among which are sterols. In this study, we sought to profile sterols and their derivatives present in the desert locust, Schistocerca gregaria, focusing on those with potential importance as dietary and therapeutic components for humans. Using coupled gas chromatography-mass spectrometry (GC-MS), we analyzed and compared the quantities of sterols in the different sections of the gut and tissues of the locust.

Cerebral amyloid β(42) deposits and microvascular pathology in ageing baboons.

Background: Previous studies have extensively reported the deposition of amyloid β (Aβ) peptide with carboxyl- and amino-terminal heterogeneity in cortical and cerebrovascular deposits in Alzheimer's disease (AD) and in non-human primates except baboons.

Methods: We examined the immunocytochemical distribution of Aβ peptides and Aβ oligomers in brain tissue from three subspecies of 18- to 28-year-old baboons (Papio) and in other monkeys including the squirrel (Saimiri sciureus) and rhesus (Macaca mulatta) for comparison.

Results: A general preponderance of Aβ(42) in parenchymal deposits and many vascular deposits in all cortical lobes was evident in the baboons.

Prevalence of substance use among college students in Eldoret, western Kenya.

Background: Substance use among college and university students predicts substance related problems in later life. Few studies on this phenomenon have been carried out in low income countries, and most focus on primary and secondary school students. This study therefore aimed to establish the prevalence and factors associated with drug use among university and college students in a low income country.

Comparison of volatile blends and gene sequences of two isolates of Metarhizium anisopliae of different virulence and repellency toward the termite Macrotermes michaelseni.

Previously, we reported an interesting relationship between virulence and repellency of different isolates of the fungus Metarhizium anisopliae towards the termite Macrotermes michaelseni: the higher the virulence of a given isolate, the greater its repellency. In the present study, we compared the volatile profiles of two isolates, one that was more virulent (and repellent) and one that was less virulent (and repellent) to the termite. The prominent components of the two blends were characterized by gas chromatography-mass spectrometry and authenticated by gas chromatography co-injections with synthetic standards.

Comparative responses of ovipositing Anopheles gambiae and Culex quinquefasciatus females to the presence of Culex egg rafts and larvae.

Field observations have demonstrated that gravid Anopheles gambiae Giles s.s. (Diptera: Culicidae) are selective in their choice of oviposition sites.

Relationship between virulence and repellency of entomopathogenic isolates of Metarhizium anisopliae and Beauveria bassiana to the termite Macrotermes michaelseni.

Termites encounter a diverse array of potentially useful and harmful fungi in their subterranean habitats. These vary from symbiotic to harmful species with varying levels of virulence. How these hemiedaphic insects survive in habitats with infective fungi is not well understood.

New mosquito larvicidal tetranortriterpenoids from Turraea wakefieldii and Turraea floribunda.

The crude methanol extracts of the root barks of Turraea wakefieldii and Turraea floribunda were found to show mosquito larvicidal activity against third-instar larvae of Anopheles gambiae sensu stricto. Four new limonoids comprising a vilasininoid 1 and three havanensinoids 2-4 were isolated from the chloroform fractions of the methanol extracts of T. wakefieldii and T.

Ring A-seco mosquito larvicidal limonoids from Turraea wakefieldii.

Five novel limonoids, 1-5, were isolated from the root bark of Turraea wakefieldii and were characterized as tecleaninoid derivatives. This is the first report of the natural occurrence of tecleanin-type limonoids with a five-membered-ring A-seco structure for which we propose the name neotecleanins. The relative stereochemical structures of compounds 1-5 were established on the basis of NMR spectroscopy.
