Mortality Among Children Under Five Years of Age Living With HIV on Antiretroviral Treatment From HIV Case Surveillance Data, Malawi, 2022.

From Malawi's HIV case surveillance, we report clinical characteristics and outcomes of 4461 children living with HIV on antiretroviral treatment aged <5 years from January to December, 2022. Among the 4% of children living with HIV who died, 43% were asymptomatic, 35% had advanced or severe symptoms at the time of HIV diagnosis and 50% died within 6 months of receiving an HIV diagnosis.

CEP hormones at the nexus of nutrient acquisition and allocation, root development, and plant-microbe interactions.

A growing understanding is emerging of the roles of peptide hormones in local and long-distance signalling that coordinates plant growth and development as well as responses to the environment. C-TERMINALLY ENCODED PEPTIDE (CEP) signalling triggered by its interaction with CEP RECEPTOR 1 (CEPR1) is known to play roles in systemic nitrogen (N) demand signalling, legume nodulation, and root system architecture. Recent research provides further insight into how CEP signalling operates, which involves diverse downstream targets and interactions with other hormone pathways.

Mpox Knowledge, Attitudes, and Practices Among Persons Presenting for JYNNEOS Vaccination-District of Columbia, August to October 2022.

Background: More than 30,000 mpox cases have been confirmed in the United States since May 2022. Mpox cases have disproportionally occurred among adult gay, bisexual, and other men who have sex with men; transgender persons; and Black and Hispanic/Latino persons. We examined knowledge, attitudes, and practices regarding mpox vaccination among adults presenting for vaccination to inform prevention efforts.

C-TERMINALLY ENCODED PEPTIDE (CEP) and cytokinin hormone signaling intersect to promote shallow lateral root angles.

Root system architecture (RSA) influences the acquisition of heterogeneously dispersed soil nutrients. Cytokinin and C-TERMINALLY ENCODED PEPTIDE (CEP) hormones affect RSA, in part by controlling the angle of lateral root (LR) growth. Both hormone pathways converge on CEP DOWNSTREAM 1 (CEPD1) and CEPD2 to control primary root growth; however, a role for CEPDs in controlling the growth angle of LRs is unknown.

CEP peptide and cytokinin pathways converge on CEPD glutaredoxins to inhibit root growth.

C-TERMINALLY ENCODED PEPTIDE (CEP) and cytokinin hormones act over short and long distances to control plant responses to environmental cues. CEP and cytokinin pathway mutants share phenotypes, however, it is not known if these pathways intersect. We show that CEP and cytokinin signalling converge on CEP DOWNSTREAM (CEPD) glutaredoxins to inhibit primary root growth.

Automated Sexual History and Self-Collection of Extragenital Chlamydia and Gonorrhea Improve Detection of Bacterial Sexually Transmitted Infections in People with HIV.

With consistently rising rates of (CT) and (GC) since 2014, the need for increased screening, testing, and treatment of bacterial sexually transmitted infections (STIs) in people at risk is clear. In this study, people with HIV were asked to complete a comprehensive audio computer-assisted self-interview sexual history at routine clinic-based laboratory visits every 3-6 months. The sexual health screening resulted in an automated summary of recommended bacterial STI tests.

A new method to visualize CEP hormone-CEP receptor interactions in vascular tissue in vivo.

C-TERMINALLY ENCODED PEPTIDEs (CEPs) control diverse responses in plants including root development, root system architecture, nitrogen demand signalling, and nutrient allocation that influences yield, and there is evidence that different ligands impart different phenotypic responses. Thus, there is a need for a simple method that identifies bona fide CEP hormone-receptor pairings in vivo and examines whether different CEP family peptides bind the same receptor. We used formaldehyde or photoactivation to cross-link fluorescently tagged group 1 or group 2 CEPs to receptors in semi-purified Medicago truncatula or Arabidopsis thaliana leaf vascular tissues to verify that COMPACT ROOT ARCHITECTURE 2 (CRA2) is the Medicago CEP receptor, and to investigate whether sequence diversity within the CEP family influences receptor binding.

Evaluation of the time to desensitization of the larynx of cats following topical lidocaine application.

Objectives: The objective of this study was to evaluate the time to decreased reactivity of the arytenoid cartilages in cats after application of topical lidocaine.

Methods: One hundred and ten mixed-breed cats were randomly assigned to one of five groups based on the time between application of lidocaine and stimulation of the larynx: 5 (T5), 15 (T15), 30 (T30), 45 (T45) or 60 (T60) s. Cats were premedicated with dexmedetomidine, ketamine and buprenorphine.

The Peptide Hormone Receptor CEPR1 Functions in the Reproductive Tissue to Control Seed Size and Yield.

The interaction of C-TERMINALLY ENCODED PEPTIDES (CEPs) with CEP RECEPTOR1 (CEPR1) controls root growth and development, as well as nitrate uptake, but has no known role in determining yield. We used physiological, microscopic, molecular, and grafting approaches to demonstrate a reproductive tissue-specific role for in controlling yield and seed size. Independent Arabidopsis () null mutants showed disproportionately large reductions in yield and seed size relative to their decreased vegetative growth.

CEP receptor signalling controls root system architecture in Arabidopsis and Medicago.

Root system architecture (RSA) influences the effectiveness of resources acquisition from soils but the genetic networks that control RSA remain largely unclear. We used rhizoboxes, X-ray computed tomography, grafting, auxin transport measurements and hormone quantification to demonstrate that Arabidopsis and Medicago CEP (C-TERMINALLY ENCODED PEPTIDE)-CEP RECEPTOR signalling controls RSA, the gravitropic set-point angle (GSA) of lateral roots (LRs), auxin levels and auxin transport. We showed that soil-grown Arabidopsis and Medicago CEP receptor mutants have a narrower RSA, which results from a steeper LR GSA.

CEP3 levels affect starvation-related growth responses of the primary root.

CEPs (C-TERMINALLY ENCODED PEPTIDEs) inhibit Arabidopsis primary root growth by unknown mechanisms. We investigated how CEP3 levels control primary root growth. CEP3 peptide application decreased cell division, S-phase cell number, root meristematic cell number, and meristem zone (MZ) size in a dose- and CEP RECEPTOR1-dependent manner.

CEP-CEPR1 signalling inhibits the sucrose-dependent enhancement of lateral root growth.

Lateral root (LR) proliferation is a major determinant of soil nutrient uptake. How resource allocation controls the extent of LR growth remains unresolved. We used genetic, physiological, transcriptomic, and grafting approaches to define a role for C-TERMINALLY ENCODED PEPTIDE RECEPTOR 1 (CEPR1) in controlling sucrose-dependent LR growth.

Perceptions of water insecurity from urban and peri-urban Haiti: A quantitative analysis.

Safe drinking water access has continued to be a growing issue in Haiti. Water accessibility, availability, and quality can have severe implications on health and safety, with those in urban areas often having more access. Key differences relating to water accessibility can be seen between the urban and peri-urban areas of Haiti.

Perceived water insecurity among adults from urban and peri-urban Haiti: A qualitative study.

Water and sanitation services are fundamental in preventing the spread of waterborne and hygiene-related diseases. However, in developing countries, such as Haiti, access to clean water continues to pose major challenges despite efforts to improve quality and reduce distance. With Léogâne being the epicenter of the earthquake in Haiti in 2010, there were dozens of interventions aimed to improve access to clean water, specifically well construction and use of water treatment strategies.

Knowledge that Acts: Evaluating the Outcomes of a Knowledge Brokering Intervention in Western Australia's Ningaloo Region.

Knowledge exchange involves a suite of strategies used to bridge the divides between research, policy and practice. The literature is increasingly focused on the notion that knowledge generated by research is more useful when there is significant interaction and knowledge sharing between researchers and research recipients (i.e.

Preoperative skin antiseptics for preventing surgical site infections: what to do?

Background: Safe and effective patient preoperative skin antisepsis is recommended to prevent surgical site infections (SSIs), reduce patient morbidity, and reduce systemic costs. However, there is lack of consensus among best practice recommendations regarding the optimal skin antiseptic solution and method of application.

Methods: In 2010 and 2011 the health technology appraisal committee of the Surgery Operational Clinical Network (SOCN), of Alberta Health Services (AHS), conducted an environmental scan to determine the current preoperative skin antisepsis in Alberta, reviewed key publications and existing guidelines, and requested a systematic review from the Canadian Agency for Drugs and Technologies in Health (CADTH).

"Measurement Monday": one facility's approach to standardizing skin impairment documentation.

Accurate, timely wound assessment and documentation is fundamental to nursing practice. A 2005 retrospective chart audit (N = 54) at a rural, 238-bed tertiary care facility in Northeastern Pennsylvania (average daily census 175 to 180) found that complete wound assessment documentation (including measurements) was lacking in 59% of patient charts. The purpose of this quality improvement initiative, led by the Wound Ostomy Continence Nurse (WOCN), was to evaluate and improve nursing assessment and documentation of impaired skin (pressure ulcers, skin tears, open surgical wounds, diabetic ulcers, and venous stasis ulcers).
