Urban malaria has become a challenge for most African countries due to urbanization, with increasing population sizes, overcrowding, and movement into cities from rural localities. The rapid expansion of cities with inappropriate water drainage systems, abundance of water storage habitats, coupled with recurrent flooding represents a concern for water-associated vector borne diseases, including malaria. This situation could threaten progress made towards malaria elimination in sub-Saharan countries, including Senegal, where urban malaria has presented as a threat to national elimination gains. To assess drivers of urban malaria in Senegal, a 5-month study was carried out from August to December 2019 in three major urban areas and hotspots for malaria incidence (Diourbel, Touba, and Kaolack) including the rainy season (August-October) and partly dry season (November–December). The aim was to characterize malaria vector larval habitats, vector dynamics across both seasons, and to identify the primary eco- environmental entomological factors contributing to observed urban malaria transmission. A total of 145 Anopheles larval habitats were found, mapped, and monitored monthly. This included 32 in Diourbel, 83 in Touba, and 30 in Kaolack. The number of larval habitats fluctuated seasonally, with a decrease during the dry season. In Diourbel, 22 of the 32 monitored larval habitats (68.75%) were dried out by December and considered temporary, while the remaining 10 (31.25%) were classified as permanent. In the city of Touba 28 (33.73%) were temporary habitats, and of those 57%, 71% and 100% dried up respectively by October, November, and December. However, 55 (66.27%) habitats were permanent water storage basins which persisted throughout the study. In Kaolack, 12 (40%) permanent and 18 (60%) temporary Anopheles larval habitats were found and monitored during the study. Three malaria vectors (An. arabiensis, An. pharoensis and An. funestus s.l.) were found across the surveyed larval habitats, and An. arabiensis was found in all three cities and was the only species found in the city of Diourbel, while An. arabiensis, An. pharoensis, and An. funestus s.l. were detected in the cities of Touba and Kaolack. The spatiotemporal observations of immature malaria vectors in Senegal provide evidence of permanent productive malaria vector larval habitats year-round in three major urban centers in Senegal, which may be driving high urban malaria incidence. This study aimed to assess the presence and type of anopheline larvae habitats in urban areas. The preliminary data will better inform subsequent detailed additional studies and seasonally appropriate, cost-effective, and sustainable larval source management (LSM) strategies by the National Malaria Control Programme (NMCP).by Siting Chen, Corey L.

IntroductionMultimorbidity may confer higher risk for cognitive decline than any single constituent disease. This study aims to identify distinct trajectories of cognitive impairment probability among middle-aged and older adults, and to assess the effect of changes in mental-somatic multimorbidity on these distinct trajectories.
MethodsData from the Health and Retirement Study (1998–2016) were employed to estimate group-based trajectory models identifying distinct trajectories of cognitive impairment probability. Four time-varying mental-somatic multimorbidity combinations (somatic, stroke, depressive, stroke and depressive) were examined for their association with observed trajectories of cognitive impairment probability with age. Multinomial logistic regression analysis was conducted to quantify the association of sociodemographic and health-related factors with trajectory group membership.
ResultsRespondents (N = 20,070) had a mean age of 61.0 years (SD = 8.7) at baseline. Three distinct cognitive trajectories were identified using group-based trajectory modelling: (1) Low risk with late-life increase (62.6%), (2) Low initial risk with rapid increase (25.7%), and (3) High risk (11.7%). For adults following along Low risk with late-life increase, the odds of cognitive impairment for stroke and depressive multimorbidity (OR:3.92, 95%CI:2.91,5.28) were nearly two times higher than either stroke multimorbidity (OR:2.06, 95%CI:1.75,2.43) or depressive multimorbidity (OR:2.03, 95%CI:1.71,2.41). The odds of cognitive impairment for stroke and depressive multimorbidity in Low initial risk with rapid increase or High risk (OR:4.31, 95%CI:3.50,5.31; OR:3.43, 95%CI:2.07,5.66, respectively) were moderately higher than stroke multimorbidity (OR:2.71, 95%CI:2.35, 3.13; OR: 3.23, 95%CI:2.16, 4.81, respectively). In the multinomial logistic regression model, non-Hispanic Black and Hispanic respondents had higher odds of being in Low initial risk with rapid increase and High risk relative to non-Hispanic White adults.
ConclusionsThese findings show that depressive and stroke multimorbidity combinations have the greatest association with rapid cognitive declines and their prevention may postpone these declines, especially in socially disadvantaged and minoritized groups.
The WHO Safe Childbirth Checklist (WHO SCC) was developed to accelerate adoption of essential practices that prevent maternal and neonatal morbidity and mortality during childbirth. This study aims to summarise the current landscape of organisations and facilities that have implemented the WHO SCC and compare the published strategies used to implement the WHO SCC implementation in both successful and unsuccessful efforts.
This scoping review protocol follows the guidelines of the Joanna Briggs Institute. Data will be collected and reported according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews report. The search strategy will include publications from the databases Scopus, PubMed, Embase, CINAHL and Web of Science, in addition to a search in grey literature in The National Library of Australia’s Trobe, DART-Europe E-Theses Portal, Electronic Theses Online Service, Theses Canada, Google Scholar and Theses and dissertations from Latin America. Data extraction will include data on general information, study characteristics, organisations involved, sociodemographic context, implementation strategies, indicators of implementation process, frameworks used to design or evaluate the strategy, implementation outcomes and final considerations. Critical analysis of implementation strategies and outcomes will be performed with researchers with experience implementing the WHO SCC.
The study does not require an ethical review due to its design as a scoping review of the literature. The results will be submitted for publication to a scientific journal and all relevant data from this study will be made available in Dataverse.
To assess student nurses understanding and skills in the application of antimicrobial stewardship knowledge to practice.
Quantitative.
Cross-sectional survey.
Five hundred and twenty three student nurses responded across 23 UK universities. Although students felt prepared in competencies in infection prevention and control, patient-centred care and interprofessional collaborative practice, they felt less prepared in competencies in which microbiological knowledge, prescribing and its effect on antimicrobial stewardship is required. Problem-based learning, activities in the clinical setting and face-to-face teaching were identified as the preferred modes of education delivery. Those who had shared antimicrobial stewardship teaching with students from other professions reported the benefits to include a broader understanding of antimicrobial stewardship, an understanding of the roles of others in antimicrobial stewardship and improved interprofessional working.
There are gaps in student nurses' knowledge of the basic sciences associated with the antimicrobial stewardship activities in which nurses are involved, and a need to strengthen knowledge in pre-registration nurse education programmes pertaining to antimicrobial management, specifically microbiology and antimicrobial regimes and effects on antimicrobial stewardship. Infection prevention and control, patient-centred care and interprofessional collaborative practice are areas of antimicrobial stewardship in which student nurses feel prepared. Interprofessional education would help nurses and other members of the antimicrobial stewardship team clarify the role nurses can play in antimicrobial stewardship and therefore maximize their contribution to antimicrobial stewardship and antimicrobial management.
There is a need to strengthen knowledge from the basic sciences, specifically pertaining to antimicrobial management, in pre-registration nurse education programmes.
No patient or public contribution.
Nurses must protect health through understanding and applying antimicrobial stewardship knowledge and skills (Nursing and Midwifery Council 2018); however, there is no research available that has investigated nurses understanding and skills of the basic sciences associated with the antimicrobial stewardship activities in which they are involved.
There are gaps in student nurses' knowledge of the basic sciences (specifically microbiology and prescribing) associated with the antimicrobial stewardship activities in which nurses are involved. Problem-based learning, and activities in the clinical setting, were reported as useful teaching methods, whereas online learning, was seen as less useful.

Ketamine has been shown to produce analgesia in various acute and chronic pain states; however, abuse liability concerns have limited its utility. The ketamine metabolite (2R,6R)-hydroxynorketamine (HNK) has been shown to produce antidepressant-like effects similar to ketamine without abuse liability concerns. (2R,6R)-HNK produces sustained analgesia in models of chronic pain, but has yet to be evaluated in models of acute pain. The present study evaluated the efficacy of acute (2R,6R)-HNK administration (one injection) in assays of pain-stimulated (52- and 56-degree hot plate test and acetic acid writhing) and pain-depressed behavior (locomotor activity and rearing) in male and female C57BL/6 mice. In assays of pain-stimulated behaviors, (2R,6R)-HNK (1–32 mg/kg) failed to produce antinociception in the 52- and 56-degree hot plate and acetic acid writhing assays. In assays of pain-depressed behaviors, 0.56% acetic acid produced a robust depression of locomotor activity and rearing that was not blocked by pretreatment of (2R,6R)-HNK (3.2–32 mg/kg). The positive controls morphine (hot plate test) and ketoprofen (acetic acid writhing, locomotor activity, and rearing) blocked pain-stimulated and pain-depressed behaviors. Finally, the effects of intermittent (2R,6R)-HNK administration were evaluated in 52-degree hot plate and pain-depressed locomotor activity and rearing. Intermittent administration of (2R,6R)-HNK also did not produce antinociceptive effects in the hot plate or pain-depressed locomotor activity assays. These results suggest that (2R,6R)-HNK is unlikely to have efficacy in treating acute pain; however, the efficacy of (2R,6R)-HNK in chronic pain states should continue to be evaluated.by Nicodemus Songose Awarayi, Frimpong Twum, James Ben Hayfron-Acquah, Kwabena Owusu-Agyemang
This study aims to develop an optimally performing convolutional neural network to classify Alzheimer’s disease into mild cognitive impairment, normal controls, or Alzheimer’s disease classes using a magnetic resonance imaging dataset. To achieve this, we focused the study on addressing the challenge of image noise, which impacts the performance of deep learning models. The study introduced a scheme for enhancing images to improve the quality of the datasets. Specifically, an image enhancement algorithm based on histogram equalization and bilateral filtering techniques was deployed to reduce noise and enhance the quality of the images. Subsequently, a convolutional neural network model comprising four convolutional layers and two hidden layers was devised for classifying Alzheimer’s disease into three (3) distinct categories, namely mild cognitive impairment, Alzheimer’s disease, and normal controls. The model was trained and evaluated using a 10-fold cross-validation sampling approach with a learning rate of 0.001 and 200 training epochs at each instance. The proposed model yielded notable results, such as an accuracy of 93.45% and an area under the curve value of 0.99 when trained on the three classes. The model further showed superior results on binary classification compared with existing methods. The model recorded 94.39%, 94.92%, and 95.62% accuracies for Alzheimer’s disease versus normal controls, Alzheimer’s disease versus mild cognitive impairment, and mild cognitive impairment versus normal controls classes, respectively.Recent research has highlighted non-operative management (NOM) as a viable alternative for frail older adults with hip fractures in the final phase of life. This study aims to guide Dutch physicians and hospitals nationwide in a standardised implementation of shared decision-making regarding surgery or NOM in selected frail older adults with a hip fracture.
The patient population for implementation includes frail older adults aged ≥70 years with an acute proximal femoral fracture, nursing home care or a similar level of care elsewhere and at least one additional criterion (ie, malnutrition, severe mobility impairment or ASA≥4). The 2-year implementation study will be conducted in four phases. In phases 1 and 2, barriers and facilitators for implementation will be identified and an implementation protocol, educational materials and patient information will be developed. Phase 3 will involve an implementation pilot in 14 hospitals across the Netherlands. The protocol and educational material will be improved based on healthcare provider and patient experiences gathered through interviews. Phase 4 will focus on upscaling to nationwide implementation and the effect of the implementation on NOM rate will be measured using data from the Dutch Hip Fracture Audit.
The study was exempted by the local Medical Research Ethics Committee (MEC-2023-0270, 10 May 2023) and Medical Ethics Committee United (W23.083, 26 April 2023). The study’s results will be submitted to an open access international peer-reviewed journal. Its protocols, tools and results will be presented at several national and international academic conferences of relevant orthogeriatric (scientific) associations.
EndoTrac is a line-attached sheath-type traction device that enables us to control the direction and the force of traction during endoscopic submucosal dissection (ESD). The efficacy of EndoTrac for gastric ESD has not been fully verified.
The G-Trac study is a multicentre (nine general hospitals and two university hospitals in Japan) collaborative trial assessing the efficacy of EndoTrac for gastric ESDs. Patients with superficial gastric neoplasms will be enrolled and randomly assigned to undergo either conventional ESD or EndoTrac ESD. Allocation will be stratified according to tumour location, operator experience and tumour diameter at an allocation rate of 1:1. The type of endoknife used will be confirmed before randomisation. The primary outcome, procedure time, will be compared between the groups in both intention-to-treat and per-protocol analyses using the Wilcoxon rank sum test. The efficacy-related, safety-related and device-related outcomes will be assessed in the secondary analysis. The planned sample size of the 142 patients in the two groups will enable us to detect a difference with a power of 80% by using the Wilcoxon rank sum test, assuming an effect size of 0.54, asymptotic relative efficiency of 0.864 and a two-sided type 1 error rate of 5%.
This trial was approved by the certified review board of Kobe University (22 December 2022). The results from this trial will be disseminated through peer-review journals, presentations at national and international conferences, and data sharing with other researchers.

To examine family planning through the community’s perception, belief system and cultural impact; in addition to identifying the determining factors for family planning uptake.
A descriptive exploratory study.
Three communities were selected from three local government areas, each in the three senatorial districts in Ekiti State.
The study was conducted among young unmarried women in the reproductive age group who were sexually active as well as married men and women in the reproductive age group who are currently living with their partners and were sexually active.
Eight focus group discussions were conducted in the community in 2019 with 28 male and 50 female participants. The audio recordings were transcribed, triangulated with notes and analysed using QSR NVivo V.8 software. Community perception, beliefs and perceptions of the utility of family planning, as well as cultural, religious and other factors determining family planning uptake were analysed.
The majority of the participants had the perception that family planning helps married couple only. There were diverse beliefs about family planning and mixed reactions with respect to the impact of culture and religion on family planning uptake. Furthermore, a number of factors were identified in determining family planning uptake—intrapersonal, interpersonal and health system factors.
The study concluded that there are varied reactions to family planning uptake due to varied perception, cultural and religious beliefs and determining factors. It was recommended that more targeted male partner engagement in campaign would boost family planning uptake.

Chronic neuroinflammation is characterized by increased blood-brain barrier (BBB) permeability, leading to molecular changes in the central nervous system that can be explored with biomarkers of active neuroinflammatory processes. Magnetic resonance imaging (MRI) has contributed to detecting lesions and permeability of the BBB. Ultra-small superparamagnetic particles of iron oxide (USPIO) are used as contrast agents to improve MRI observations. Therefore, we validate the interaction of peptide-88 with laminin, vectorized on USPIO, to explore BBB molecular alterations occurring during neuroinflammation as a potential tool for use in MRI. The specific labeling of NPS-P88 was verified in endothelial cells (hCMEC/D3) and astrocytes (T98G) under inflammation induced by interleukin 1β (IL-1β) for 3 and 24 hours. IL-1β for 3 hours in hCMEC/D3 cells increased their co-localization with NPS-P88, compared with controls. At 24 hours, no significant differences were observed between groups. In T98G cells, NPS-P88 showed similar nonspecific labeling among treatments. These results indicate that NPS-P88 has a higher affinity towards brain endothelial cells than astrocytes under inflammation. This affinity decreases over time with reduced laminin expression. In vivo results suggest that following a 30-minute post-injection, there is an increased presence of NPS-P88 in the blood and brain, diminishing over time. Lastly, EAE animals displayed a significant accumulation of NPS-P88 in MRI, primarily in the cortex, attributed to inflammation and disruption of the BBB. Altogether, these results revealed NPS-P88 as a biomarker to evaluate changes in the BBB due to neuroinflammation by MRI in biological models targeting laminin.Non-adherence to antihypertensive medication significantly contributes to inadequate blood pressure control. Regarding non-pharmacological interventions to improve medication adherence, the question remains of which interventions yield the highest efficacy.
Understanding the complementary perspectives of patients and healthcare professionals can be valuable for designing strategies to enhance medication adherence. Few studies explored the perspectives of patients and healthcare professionals regarding medication adherence. None of them focused specifically on adherence to pharmacological therapy for hypertension in Portugal.
Considering the high prevalence of non-adherence and its location-specific aspects, the priority should be identifying its barriers and developing tactics to address them.
This study aims to gather the perspectives of patients with hypertension and healthcare professionals such as family doctors, nurses and community pharmacists from Portugal, regarding the most effective strategies to enhance antihypertensive medication adherence and to understand the factors contributing to non-adherence.
We will conduct qualitative research through synchronous online focus groups of 6–10 participants. Some groups will involve patients with hypertension, while others will include family doctors, nurses and community pharmacists. The number of focus groups will depend on the achievement of theoretical saturation. A purposive sample will be used. Healthcare participants will be recruited via email, while patients will be recruited through their family doctors.
The moderator will maintain neutrality while ensuring interactive contributions from every participant. Participants will be encouraged to express their opinions on the meeting summary. Meetings will be recorded and transcribed.
Two researchers will perform content analyses using MAXQDA V.12 through comparative analyses and subsequent consensus. A third researcher will review the analyses. The results will be presented narratively.
The Ethics Committee of the University of Coimbra has approved this study with the number: CE-026/2021. The results will be disseminated via peer-reviewed publications and national and international conferences.
En esta reseña, José Siles analiza y describe las características del último poemario del poeta Salvadoreño André Cruchaga.
Una de las principales novedades del debate parlamentario de la ley de beneficencia en el Trienio Liberal radicó en las delaciones de irregularidades en la gestión de este tipo de establecimientos. La meta principal de este estudio es analizar dichas denuncias sobre la base de una triple diferenciación: las que apuntan a las irregularidades debidas a una mala gestión de los recursos económicos, las que se refieren a la administración concejil y las que tienen que ver con la dejadez de quienes cuidaban a los menesterosos en tales casas. Los debates parlamentarios del Trienio liberal en la Ley de Beneficencia se constituyen como fuente principal del estudio. Metodológicamente se aborda el análisis de las intervenciones de los diputados que participaron en la elaboración de dicha normativa. Lo extraño en esta época no eran estas irregularidades, asumidas como algo natural, sino el hecho de que fueran denunciadas por los parlamentarios, pues ello evidencia un cambio sustancial en cuanto a la voluntad de controlar la gestión económica de estos establecimientos, así como la responsabilidad de los cuidadores.
In this paper, we present our experience with acute and chronic penile ulcers resulting from injection of an exogenous substance and their surgical treatment.
Community health workers are essential to front-line health outreach throughout low-income and middle-income countries, including programming for early childhood immunisation. Understanding how community health workers are engaged for successful early childhood vaccination among countries who showed success in immunisation coverage would support evidence-based policy guidance across contexts.
We employed a multiple case study design using qualitative research methods.
We conducted research in Nepal, Senegal and Zambia.
We conducted 207 interviews and 71 focus group discussions with 678 participants at the national, regional, district, health facility and community levels of the health systems of Nepal, Senegal and Zambia, from October 2019 to April 2021. We used thematic analysis to investigate contributing factors of community health worker programming that supported early childhood immunisation within each country and across contexts.
Implementation of vaccination programming relied principally on the (1) organisation, (2) motivation and (3) trust of community health workers. Organisation was accomplished by expanding cadres of community health workers to carry out their roles and responsibilities related to vaccination. Motivation was supported by intrinsic and extrinsic incentives. Trust was expressed by communities due to community health worker respect and value placed on their work.
Improvements in immunisation coverage was facilitated by community health worker organisation, motivation and trust. With the continued projection of health worker shortages, especially in low-income countries, community health workers bridged the equity gap in access to vaccination services by enabling wider reach to underserved populations. Although improvements in vaccination programming were seen in all three countries—including government commitment to addressing human resource deficits, training and remuneration; workload, inconsistency in compensation, training duration and scope, and supervision remain major challenges to immunisation programming. Health decision-makers should consider organisation, motivation and trust of community health workers to improve the implementation of immunisation programming.

AI assistants could be used to draft responses for physicians and nurses, potentially addressing a key element of burn-out. Further research is needed to assess the impact of communication on healthcare outcomes and should incorporate patient evaluations and feedback.
In the setting of increasing adoption of virtual healthcare and the surge in electronic patient messages, there has been a higher workload for physicians and nurses, contributing to burnout and potentially terse, unanswered or unhelpful patient messages. Given these challenges, there is a need to explore innovative solutions...
To explore home-dwelling people with dementia and family members' perceptions of the feasibility and acceptability of an intervention using dementia-related literature excerpts to facilitate conversations on ethical issues related to living with dementia.
Ethical issues in dementia care emerge throughout the illness. In the early stages, they may involve decisions about disclosing the illness to the family, shifting roles and responsibilities, and considerations of transitioning to a nursing home. Addressing ethical issues and providing adequate support to home-dwelling people with dementia and their families are often lacking.
An exploratory-descriptive qualitative study.
We conducted eight interviews with 14 home-dwelling persons with dementia and their family caregivers. Six were dyadic interviews, and two were individual interviews with family caregivers. We analysed the interview data using template analysis. We adhered to the COREQ checklist in reporting this study.
Using excerpts from dementia-related literature was a feasible and acceptable way of initiating discussions on ethical issues among home-dwelling persons with dementia and family caregivers. However, engaging the families of newly diagnosed individuals was challenging due to emotional distress. The intervention provided peer support, including identifying with others and sharing experiences. Moreover, participating couples found intimacy and relational attunement through shared reflections.
Based on the findings, it appears that the participants in this study felt that using excerpts from dementia-related literature to deliberate on ethical issues was feasible and acceptable. Deliberating on ethical issues with peers and family caregivers offers valuable social support and opportunities for strengthening relationships.
This study makes an important contribution by providing valuable insights into how ethical issues related to living with dementia can be addressed using related literature and suggests how the intervention can be integrated into existing care initiatives for home-dwelling people with dementia and their families.
We have adhered to relevant EQUATOR guidelines with the COREQ reporting method.
A healthcare professional working as a so-called dementia coordinator (a title used in the Danish context) was involved in the conduct of this study by being responsible for the recruitment of home-dwelling people with dementia and their family members. Moreover, she had joint responsibility for facilitating the intervention along with the first author.
