Morobe Province: Text summaries, maps, code lists and village identification

The major purpose of the Papua New Guinea Agricultural Systems Project is to produce information on small holder (subsistence) agriculture at provincial and national levels (Allen et al 1995). Information was collected by field observation, interviews with villagers and reference to published and unpublished documents. Methods are described by Bourke et al. (1993). This Working Paper contains a written summary of the information on the Agricultural Systems in this Province, maps of the location of agriculture systems, a complete listing of all information in the database in coded form, and lists of villages with National Population Census codes, indexed by agricultural systems. This information is available as a map-linked database (GIS) suitable for use on a personal computer in ESRI and MapInfo formats. An Agricultural System is identified when a set of similar agricultural crops and practices occur within a defined area. Six criteria are used to distinguish one system from another: 1. Fallow type (the vegetation which is cleared from a garden site before cultivation). 2. Fallow period (the length of time a garden site is left unused between cultivations). 3. Cultivation intensity (the number of consecutive crops planted before fallow). 4. The staple, or most important, crops. 5. Garden and crop segregation (the extent to which crops are planted in separate gardens; in separate areas within a garden; or are planted sequentially). 6. Soil fertility maintenance techniques (other than natural regrowth fallows). Where one or more of these factors differs significantly and the differences can be mapped, then a separate system is distinguished. Where variation occurs, but is not able to be mapped at 1:500 000 scale because the areas in which the variation occurs are too small or are widely dispersed within the larger system, a subsystem is identified. Subsystems within an Agricultural System are allocated a separate record in the database, identified by the Agricultural System number and a subsystem number. Sago is a widespread staple food in lowland Papua New Guinea. Sago is produced from palms which are not grown in gardens. Most of the criteria above cannot be applied. In this case, systems are differentiated on the basis of the staple crops only. The Papua New Guinea Resource Information System (PNGRIS) is a GIS which contains information on the natural resources of PNG (Bellamy 1986). PNGRIS contains no information on agricultural practices, other than an assessment of land use intensity based on air photograph interpretation by Saunders (1993. The Agricultural Systems Project is designed to provide detailed information on agricultural practices and cropping patterns as part of an upgraded PNGRIS geographical information system. For this reason the Agricultural Systems database contains almost no information on the environmental settings of the systems, except for altitude and slope. The layout of the text descriptions, the database code files and the village lists are similar to PNGRIS formats (Cuddy 1987). The mapping of Agricultural Systems has been carried out on the same map base and scale as PNGRIS (Tactical Pilotage Charts, 1:500 000). Agricultural Systems were mapped within the areas of agricultural land use established by Saunders (1993) from aerial photography. Except where specifically noted, Agricultural Systems boundaries have been mapped without reference to PNGRIS Resource Mapping Unit (RMU) boundaries. Agricultural Systems are defined at the level of the Province (following PNGRIS) but their wider distribution is recognised in the database by cross-referencing systems which cross provincial borders. A preliminary view of the relationships between PNGRIS RMUs and the Agricultural Systems in this Province can be obtained from the listing of villages by Agricultural System, where RMU numbers are appended.

Physical and Cultural Activity for Life Skills Development - Comparative Report

Life skills are defined as psychosocial abilities for adaptive and positive behaviour that enable individuals to deal effectively with the demands and challenges of everyday life. Life skills can be fostered and are fundamental for a person’s progression in life, both personal and professional. Some of those skills are creativity, critical thinking, problem-solving, effective communication and collaboration skills, cultivation of responsibility, development of healthy relationships and decision- making. These skills can be acquired through life experience but can be further developed through constant training and engagement. Life skills are particularly important for adolescents and young people. Adolescents and young people leave behind the dependence and the safety that childhood is associated with and enter adulthood with all its opportunities and freedoms but also with all its insecurities and anxieties. Life skills can help adolescents and young people strengthen their self-confidence, interpersonal skills, learn how to use them in assessing knowledge, use resources for their benefit, and make the proper decisions in order to promote their wellbeing2. This way life skills can help young people anticipate with all the difficulties that might occur in adulthood and be involved in the society. In other words, life skills can equip young people with all the necessary qualities in order to become resilient individuals and active citizens. The University of Gloucestershire (UK), Play Gloucestershire (UK), Rogers Személyközpontú Oktatásért Alapítvány (HU), KENTRO MERIMNAS OIKOGENEIAS KAI PAIDIOU(GR), CESIE (IT) and CLAVIS sprog & competence (DK) are implementing the 2 year Erasmus+ project entitled: PAClife – Physical and Cultural Activity for Life Skills Development (2020-2021). The project aims to support disadvantaged and migrant young people in building resilience through acquiring and developing life skills and key competences by participating in a programme of physical and cultural activity. This report presents the findings of a desk-based comparison of domestic projects that will inform the future development of the PAClife training tool to low-skilled/low qualified migrant and disadvantaged young people

Effects of dietary nitrate supplementation on symptoms of acute mountain sickness and basic physiological responses in a group of male adolescents during ascent to Mount Everest Base Camp

The purpose of this study was to investigate the effects of dietary nitrate supplementation, in the form of beetroot juice, on acute mountain sickness (AMS) symptoms and physiological responses, in a group of young males trekking to Mount Everest Base Camp (EBC). Forty healthy male students (mean age (SD): 16 (1) yrs) trekked to EBC over 11 days. Following an overnight fast, each morning participants completed the Lake Louise AMS questionnaire and underwent a series of physiological tests: resting blood pressure as well as resting and exercising heart rate, respiratory rate, and peripheral oxygen saturation. The exercise test consisted of a standardised 2-minute stepping protocol and measurements were taken in the last 10 seconds. Participants in the intervention arm of the study consumed 140 ml of concentrated beetroot juice daily, containing approximately 10 mmoles of nitrate, while those in the control arm consumed 140 ml of concentrated blackcurrant cordial with negligible nitrate content. Drinks were taken for the first seven days at high altitude (days 2 to 8), in two equal doses; one with breakfast, and one with the evening meal. Mixed modelling revealed no significant between-groups difference in the incidence of AMS (Odds Rationitrate vs. control: 1.16 (95% CI: 0.59; 2.29)). Physiological changes occurring during ascent to high altitude generally were not significantly different between the two groups (Model Coef (95% CI) – average difference nitrate vs. control: systolic blood pressure, 0.16 (-4.47; 4.79); peripheral oxygen saturation, 0.28 (-0.85; 1.41); heart rate, -0.48 (-8.47; 7.50) (Model Coef (95% CI) – relative difference nitrate vs. control: ventilatory rate, 0.95 (0.82; 1.08)). Modelling revealed that diastolic blood pressure was 3.37 mmHg (0.24; 6.49) higher for participants in the beetroot juice, however this difference was no larger than that found at baseline and no interaction effect was observed. Supplementation with dietary nitrate did not significantly change symptoms of AMS or alter key physiological variables, in a group of adolescent males during a high altitude trekking expedition. There was no evidence of harm from dietary nitrate supplementation in this context. Given the wide confidence intervals in all models, a larger sample size would be required to exclude a false negative result. Our data suggest that prolonged oral nitrate supplementation is safe and feasible at altitude but has little physiological or clinical effect

Human Leptospirosis Caused by a New, Antigenically Unique Leptospira Associated with a Rattus Species Reservoir in the Peruvian Amazon

As part of a prospective study of leptospirosis and biodiversity of Leptospira in the Peruvian Amazon, a new Leptospira species was isolated from humans with acute febrile illness. Field trapping identified this leptospire in peridomestic rats (Rattus norvegicus, six isolates; R. rattus, two isolates) obtained in urban, peri-urban, and rural areas of the Iquitos region. Novelty of this species was proven by serological typing, 16S ribosomal RNA gene sequencing, pulsed-field gel electrophoresis, and DNA-DNA hybridization analysis. We have named this species “Leptospira licerasiae” serovar Varillal, and have determined that it is phylogenetically related to, but genetically distinct from, other intermediate Leptospira such as L. fainei and L. inadai. The type strain is serovar Varillal strain VAR 010T, which has been deposited into internationally accessible culture collections. By microscopic agglutination test, “Leptospira licerasiae” serovar Varillal was antigenically distinct from all known serogroups of Leptospira except for low level cross-reaction with rabbit anti–L. fainei serovar Hurstbridge at a titer of 1∶100. LipL32, although not detectable by PCR, was detectable in “Leptospira licerasiae” serovar Varillal by both Southern blot hybridization and Western immunoblot, although on immunoblot, the predicted protein was significantly smaller (27 kDa) than that of L. interrogans and L. kirschneri (32 kDa). Isolation was rare from humans (2/45 Leptospira isolates from 881 febrile patients sampled), but high titers of MAT antibodies against “Leptospira licerasiae” serovar Varillal were common (30%) among patients fulfilling serological criteria for acute leptospirosis in the Iquitos region, and uncommon (7%) elsewhere in Peru. This new leptospiral species reflects Amazonian biodiversity and has evolved to become an important cause of leptospirosis in the Peruvian Amazon

A 51-year-old Aboriginal woman from northern Saskatchewan presented to a local family medical clinic in early October 2006 with a three-day history of left knee pain. Her vital signs included a blood pressure of 114/70 mmHg, a heart rate of 100 beats/min and a respiratory rate of 20 breaths/min. Her temperature was not documented. On examination, her knee was warm and painful, and an effusion was noted. Approximately six weeks prior, she had fallen on her right knee while walking. This injury was complicated by hemarthrosis and effusion, requiring needle drainage on two occasions. In addition, she had a history of pain, swelling and erythema involving her shoulder joint. Her past history was significant for alcohol abuse and unstable social and housing conditions. The laboratory results showed the followingwhite blood cell (WBC) count 9.8×10 9 /L (normal 0.2×10 9 /L to 10×10 9 /L); granulocyte count 8.8×10 9 /L (normal 2×10 9 /L to 7.8×10 9 /L); hemoglobin (Hb) level 102 g/L (normal 120 g/L to 180 g/L) and platelet count 68×10 9 /L (normal 150×10 9 /L to 450×10 9 /L). A presumptive diagnosis of inflammatory arthritis was made, and she was given indomethacin 50 mg three times a day for her symptoms. Two days later, the patient became progressively more confused, disoriented and unresponsive to questions. She was brought by ambulance to the local emergency department where her temperature was 38.8°C, pulse 98 beats/min, blood pressure 140/83 mmHg and respiratory rate 32 breaths/min. Her Glasgow coma scale score was 6. She was unresponsive to verbal commands but responsive to painful stimuli. Bruising was noted on both legs, and a large area of erythema was noted around the left knee. Her respiratory examination was unremarkable. Laboratory results showed the following -WBC count 3. 135 U/L) and creatine kinase isoenzyme -MB level 28 U/L (normal 0 U/L to 16 U/L). An evolving neurological condition was thought to be the primary diagnosis. Initial management included intravenous fluid (200 mL/h), cefotaxime 2 g administered intravenously, and blood cultures. She was transferred by air to the Royal University Hospital in Saskatoon, Saskatchewan. During the 1 h flight to Saskatoon, the area of erythema on her left leg tripled in size, and 3 L of intravenous fluids and dopamine were required to stabilize her blood pressure. On arrival, she was noted to be diffusely rigid with no response to painful stimuli. Her temperature was 39°C. She had rigors, peripheral mottling, absence of peripheral pulses, bronchial breath sounds over the right middle lobe, and erythema and target-like lesions over her left knee. Laboratory evaluation on admission showed the following -WBC count 3.

The “ebb and flow” of student learning on placement

There is a rise in interest in work based learning as part of student choice at subject level in the UK (DOE 2017) but there remains an absence of specific guidance on how to best support higher education students learning on placement. An alternative HE experience in England, the degree apprenticeship, underlies the continued focus by policy in securing placement experiences for students without stipulating the type of support that is required at the ‘coal face’ of work based learning. Policy documents (UUK 2016), that urge universities to enter into partnership agreements with both employers and FE colleges to plug skills shortages, are noticeably lacking in their appreciation of the unique qualities of work based learning and how best to support students in this setting (Morley 2017a). Unfortunately, this is not unusual as placements have predominantly been an enriching ‘add on’ to the real business of academic learning in more traditional university programmes. Support initiatives, such as that described in chapter 9, are a rare appreciation of the importance of this role. Undergraduate nursing programmes currently support a 50:50 split between practice learning in clinical placements and the theory delivered at universities. Vocational degrees, such as this, provide an interesting case study as to how students can be supported in the practice environment by an appreciation of how students really learn on placement and how hidden resources can be utilised more explicitly for practice learning. During 2013 – 2015 a professional doctorate research study (Morley 2015) conducted a grounded theory study of 21 first year student nurses on their first placement to discover how they learnt ‘at work’ and the strategies they enlisted to be successful work based learners

A Comparative Study of Leptospirosis and Dengue in Thai Children

Two of the most common causes of acute febrile illnesses among children in the tropics are leptospirosis and dengue. Early in illness, these two conditions are often indistinguishable and rapid laboratory confirmation of the infecting pathogen is generally not available. An enhanced ability to distinguish leptospirosis from dengue in children would guide clinicians and public health personnel in the appropriate use of limited healthcare resources

Detection and Quantification of Leptospira interrogans in Hamster and Rat Kidney Samples: Immunofluorescent Imprints versus Real-time PCR

A major limitation in the clinical management and experimental research of leptospirosis is the poor performance of the available methods for the direct detection of leptospires. In this study, we compared real-time PCR (qPCR), targeting the lipL32 gene, with the immunofluorescent imprint method (IM) for the detection and quantification of leptospires in kidney samples from the rat and hamster experimental models of leptospirosis. Using a virulent strain of Leptospira interrogans serovar Copenhageni, a chronic infection was established in the rat model, which were euthanized 28 days post-infection, while the hamster model simulated an acute infection and the hamsters were euthanized eight days after inoculation. Leptospires in the kidney samples were detected using culture isolation, qPCR and the IM, and quantified using qPCR and the IM. In both the acute and chronic infection models, the correlation between quantification by qPCR and the IM was found to be positive and statistically significant (P<0.05). Therefore, this study demonstrates that the IM is a viable alternative for not only the detection but also the quantification of leptospires, particularly when the use of qPCR is not feasible
