Academic accountability to local communities and society through Programme Science: a case study from the HPV self-sampling programme HOPE in Peru.

Introduction: Health challenges in the 21st century underscore the need for adaptable and innovative approaches in public health. Academic institutions can and should contribute much more effectively to generate and translate scientific knowledge that will result in better programmes to improve societal health. Academic accountability to local communities and society requires universities to actively engage with local communities, understanding the context, their needs, and leveraging their knowledge and local experience.

[Septic shock originating from a pulmonary focus caused by Pasteurella multocida. Report of one case].

Pasteurella multocida is a gram-negative coccobacillus bacterium found as a commensal in the oropharynx of domestic animals such as cats and dogs and some farm animals. Soft tissue infections and occasionally bacteremia in immunocompromised patients with direct contact with animals are described. We report a 61 year old male with a history of scratches and close contact with domestic cats, with a septic shock originating from a pulmonary focus, requiring mechanical ventilation and vasopressors.

Multilevel visuomotor control of locomotion in Drosophila.

Vision is critical for the control of locomotion, but the underlying neural mechanisms by which visuomotor circuits contribute to the movement of the body through space are yet not well understood. Locomotion engages multiple control systems, forming distinct interacting "control levels" driven by the activity of distributed and overlapping circuits. Therefore, a comprehensive understanding of the mechanisms underlying locomotion control requires the consideration of all control levels and their necessary coordination.

Circuits for self-motion estimation and walking control in Drosophila.

The brain's evolution and operation are inextricably linked to animal movement, and critical functions, such as motor control, spatial perception, and navigation, rely on precise knowledge of body movement. Such internal estimates of self-motion emerge from the integration of mechanosensory and visual feedback with motor-related signals. Thus, this internal representation likely depends on the activity of circuits distributed across the central nervous system.

Motion vision: Drosophila neural pathways that go with the visual flow.

Processing visual motion cues to interpret self-motion, the movement of others, and the environment's structure is vital to all animals, whether prey or predator. A new study in Drosophila identifies multiple pathways likely contributing to visual motion-dependent computations and behaviors.

Evaluation of Women's Empowerment in a Community-Based Human Papillomavirus Self-Sampling Social Entrepreneurship Program (Hope Project) in Peru: A Mixed-Method Study.

Introduction: Understanding community women's relational and financial empowerment in social entrepreneurship could be the key to scaling up community-based human papillomavirus (HPV) self-sampling programs in low- and middle-income countries. The Hope Project, social entrepreneurship in Peru, trains women (Hope Ladies) to promote HPV self-sampling among other women in their communities. This study aims to evaluate the Hope Ladies' relational and financial empowerment after participating in the program.

Walking strides direct rapid and flexible recruitment of visual circuits for course control in Drosophila.

Flexible mapping between activity in sensory systems and movement parameters is a hallmark of motor control. This flexibility depends on the continuous comparison of short-term postural dynamics and the longer-term goals of an animal, thereby necessitating neural mechanisms that can operate across multiple timescales. To understand how such body-brain interactions emerge across timescales to control movement, we performed whole-cell patch recordings from visual neurons involved in course control in Drosophila.

The ARMADILLO text message intervention to improve the sexual and reproductive health knowledge of adolescents in Peru: Results of a randomized controlled trial.

Background: The ARMADILLO Study determined whether adolescents able to access SRH information on-demand via SMS were better able to reject contraception-related myths and misconceptions as compared with adolescents receiving pushed SMS or no intervention.

Trial Design: This trial was an unblinded, three-arm, parallel-group, individual RCT with a 1:1:1 allocation. Trial registration: ISRCTN85156148.

Fast tuning of posture control by visual feedback underlies gaze stabilization in walking Drosophila.

Locomotion requires a balance between mechanical stability and movement flexibility to achieve behavioral goals despite noisy neuromuscular systems, but rarely is it considered how this balance is orchestrated. We combined virtual reality tools with quantitative analysis of behavior to examine how Drosophila uses self-generated visual information (reafferent visual feedback) to control gaze during exploratory walking. We found that flies execute distinct motor programs coordinated across the body to maximize gaze stability.

DeepEthogram, a machine learning pipeline for supervised behavior classification from raw pixels.

Videos of animal behavior are used to quantify researcher-defined behaviors of interest to study neural function, gene mutations, and pharmacological therapies. Behaviors of interest are often scored manually, which is time-consuming, limited to few behaviors, and variable across researchers. We created DeepEthogram: software that uses supervised machine learning to convert raw video pixels into an ethogram, the behaviors of interest present in each video frame.

Developing an SMS text message intervention on sexual and reproductive health with adolescents and youth in Peru.

Background: Improved access to sexual and reproductive health (SRH) services and information is essential for supporting adolescents and youth in making informed decisions and optimizing each young person's outcomes related to their SRH, health and well-being and countries' current and future social and economic development. Mobile phones offer opportunities for young people to privately access SRH content and to be linked to SRH services. The objective of this study was to develop the content for an SMS (short message service or "text message") platform jointly with adolescents and youth in three regions in Peru (Lima, Ayacucho and Loreto) as part of the ARMADILLO (Adolescent/Youth Reproductive Mobile Access and Delivery Initiative for Love and Life Outcomes) Study.

A Single MicroRNA-Hox Gene Module Controls Equivalent Movements in Biomechanically Distinct Forms of Drosophila.

Movement is the main output of the nervous system. It emerges during development to become a highly coordinated physiological process essential to survival and adaptation of the organism to the environment. Similar movements can be observed in morphologically distinct developmental stages of an organism, but it is currently unclear whether or not these movements have a common molecular cellular basis.

Quality assurance for antimicrobial susceptibility testing of in Latin American and Caribbean countries, 2013-2015.

Objectives: A antimicrobial susceptibility quality control comparison programme was re-established in Latin America and the Caribbean to ensure antimicrobial susceptibility data produced from the region are comparable nationally and internationally.

Methods: Three panels, consisting of isolates comprising reference strains and other characterised isolates were sent to 11 participating laboratories between 2013 and 2015. Antimicrobial susceptibilities for these isolates were determined using agar dilution, Etest or disc diffusion methods.

Sexual health knowledge and practices and STI/HIV prevalence among long-distance truck drivers in Peru.

Objectives: HIV and other sexually transmitted infections remain a challenge globally and many key groups have yet to be studied. Evidence shows that truck drivers may have high-risk behaviors and higher sexually transmitted infection/HIV prevalence because they are a highly mobile population. However, there is little to no information on this group in Peru.

The odyssey of linking to and staying in HIV care among male sex workers in Peru.

Background: In Peru, there is little information about the HIV care continuum. Therefore, we conducted a study to describe the HIV care continuum among male sex workers (MSWs) in Lima.

Methods: We applied close-ended surveys with 209 MSWs about their engagement in the HIV care continuum and open-ended surveys with 34 MSWs who are people living with HIV (PLHIV) to explore their linkage to and retention in HIV care.

Sensation during Active Behaviors.

A substantial portion of our sensory experience happens during active behaviors such as walking around or paying attention. How do sensory systems work during such behaviors? Neural processing in sensory systems can be shaped by behavior in multiple ways ranging from a modulation of responsiveness or sharpening of tuning to a dynamic change of response properties or functional connectivity. Here, we review recent findings on the modulation of sensory processing during active behaviors in different systems: insect vision, rodent thalamus, and rodent sensory cortices.

Barriers and Solutions to Conducting Large International, Interdisciplinary Research Projects.

Global environmental problems such as climate change are not bounded by national borders or scientific disciplines, and therefore require international, interdisciplinary teamwork to develop understandings of their causes and solutions. Interdisciplinary scientific work is difficult enough, but these challenges are often magnified when teams also work across national boundaries. The literature on the challenges of interdisciplinary research is extensive.

[Complex trauma].

The effects of trauma have been the focus of study by several researchers. However, at present, there is no diagnostic criteria that includes all forms of clinical presentations of subjects who have been victims of prolonged trauma or that have started at developmentally vulnerable times in the victim's life. Unlike those individuals who are victims of a single traumatic event, individuals who suffer multiple traumas that occur at vulnerable times, are at risk of developing a complex trauma.

[Prevalence of bacterial vaginosis and associated factors in twenty peruvian cities].

Objetives.: To determine the prevalence of bacterial vaginosis (BV) and associated factors among 18-29-year-old women in 20 Peruvian cities using PREVEN project data.

Materials And Methods.

A faithful internal representation of walking movements in the Drosophila visual system.

The integration of sensorimotor signals to internally estimate self-movement is critical for spatial perception and motor control. However, which neural circuits accurately track body motion and how these circuits control movement remain unknown. We found that a population of Drosophila neurons that were sensitive to visual flow patterns typically generated during locomotion, the horizontal system (HS) cells, encoded unambiguous quantitative information about the fly's walking behavior independently of vision.

Partner Notification Among Peruvian Pregnant Women With Syphilis.

Introduction: As part of an implementation research study on the feasibility of implementing point-of-care tests for syphilis in Peru, we collected information on partner treatment of syphilis-seropositive pregnant women and explored womens' and health providers' knowledge and practices regarding partner notification and treatment (PNT) for maternal syphilis.

Methods: Mixed methods were used to collect information. Quantitative data were collected from consecutive pregnant women with a positive point-of-care test for syphilis.

Operations research study to implement HIV and syphilis point-of-care tests and assess client perceptions in a marginalised area of Lima, Peru.

In Peru, a significant proportion of people tested for HIV and syphilis do not receive timely results. Our objective was to assess the institutional feasibility of implementing simultaneous HIV/syphilis point-of-care tests and client perceptions regarding these point-of-care tests. Point-of-care tests were implemented in a hospital consultation room in a marginalised zone of Lima.

Reaching the unreachable: providing STI control services to female sex workers via mobile team outreach.

Background: As part of a community-randomized trial of a multicomponent intervention to prevent sexually transmitted infections, we created Mobile Teams (MTs) in ten intervention cities across Peru to improve outreach to female sex workers (FSW) for strengthened STI prevention services.

Methods: Throughout 20 two-month cycles, MTs provided counseling; condoms; screening and specific treatment for Neisseria gonorrhoeae (NG), Chlamydia trachomatis (CT), and vaginal Trichomonas vaginalis (TV) infections; and periodic presumptive metronidazole treatment for vaginal infections.

Results: MTs had 48,207 separate encounters with 24,814 FSW; numbers of sex work venues and of FSW reached increased steadily over several cycles.
