The objective of this study was to determine the accuracy and reliability of 2 optical chlorophyll meters:FieldScout CM 1,000 NDVI and Yara N-Tester, in predicting neutral detergent fibre(NDF), acid detergent fibre(ADF), acid detergent lignin(ADL), acid detergent insoluble nitrogen(ADIN) and in vitro ruminal organic matter degradability(IVOMD) of 3 tropical grasses. Optical chlorophyll measurements were taken at 3 stages(4, 8 and 12 weeks) of regrowth in Brachiaria hybrid, and Megathyrsus maximus and at 6 and 12 weeks of regrowth in Paspalum atratum(cv. Ubon). Optical chlorophyll measurements showed the highest correlation(r = 0.57 to 0.85) with NDF concentration. The FieldScout CM 1,000 NDVI was better than the Yara N-Tester in predicting NDF(R^2 = 0.70) and ADF(R^2 = 0.79) concentrations in Brachiaria hybrid and NDF(R^2 = 0.79) in M. maximus. Similarly, FieldScout CM 1,000 NDVI produced better estimates of 24 h IVOMD(IVOMD_(24 h)) in Brachiaria hybrid(R^2 = 0.81) and IVOMD_(48 h) in Brachiaria hybrid(R^2 = 0.65) and M. maximus(R^2 = 0.75). However, these prediction models had relatively low concordance correlation coefficients, i.e., CCC >0.90, but random errors were the main source of bias. It was,therefore, concluded that both optical chlorophyll meters were poor and unreliable predictors of ADIN and ADL concentrations. Overall, the FieldScout CM 1,000 NDVI shows potential to produce useful estimates of IVOMD_(24h) and ADF in Brachiaria hybrid and IVOMD_(48 h) and NDF concentrations in M. maximus.

The aim of this study was to compare lower limb blood flow in asymptomatic diabetic patients with early-stage peripheral artery disease (PAD) and non-diabetic controls using duplex ultrasound parameters. This was a comparative cohort study of lower limb blood flow in 35 Black-African diabetic patients (25 females and 10 males with early-stage PAD median age 54 [IQR, 47 - 61] years;median HbA1c 6.3 [IQR, 5.7 - 8.0]%;BMI 29.2 ± 6.7;ABI 1.1 ± 0.1) and 36 non-diabetic controls (28 females and 8 males;median age 54 [IQR, 47 - 61] years;median HbA1c 6.3 [IQR, 5.7 - 8.0] %, BMI 29.2 ± 6.7;ABI 1.1 ± 0.1). Peak systolic velocity (PSV), pulsatility index (PI) and resistive index (RI), were utilised to compare blood flow in the popliteal arteries (PA), anterior tibial arteries (ATA) and posterior tibial arteries (PTA) in addition to ankle brachial index. All the ultrasound parameters showed good (ICC ≥ 0.7;0.50 - 0.85, 95% CI) to excellent (ICC = 1.0;1.0 - 1.0, 95% CI) reliability within groups as well as acceptable variability () other than pulsatility index of the anterior tibial artery within diabetic patients (11.1% CV). PSV, RI and PI were significantly and meaningfully higher (P;d ≥ 0.33), in diabetic patients compared to non-diabetic controls except for PI - PTA (P = 0.72;d = 0.11). Differences in PSV and RI highlighted the effects of early-stage PAD on lower limb blood flow of diabetic patients. In contrast, the effects of early-stage PAD on blood flow were not demonstrated in the PTA and ATA of diabetic patients by PI.

Forest biomass has great potential as a biofuel feedstock, but information on forest owner perceptions of using forest biomass to produce bioenergy is lacking. In this case study, we surveyed 3500 small to medium private forest landowners in southwestern Louisiana to better understand their attitudes and perceptions towards harvesting forest biomass for bioenergy production. Results indicate that landowners: 1) were positive about utilizing biomass for bioenergy, 2) believe viable biomass conversion technologies exist, 3) had antagonistic or neutral attitudes towards some technological, economic, and policy issues associated with using forest biomass for bioenergy due in part to lack of information or knowledge, and 4) felt biomass is a low-value product compared to traditional products. Landowners’ perceptions of participating in bio-based activities and markets vary among age and ownership size, and 51% of forest landowners were willing to participate in management activities specifically geared for bioenergy production.

Background: Operative vaginal delivery is a common obstetric intervention, with the potential to cause harm to mother and baby. Training in operative delivery traditionally comprised junior trainees learning the skills under supervision, then practicing and refining them independently. Recently this model has come under scrutiny, with the advent of simulation-based training suggesting a method by which the skills of safe delivery may be taught without risk. Multiple training courses exist, but few have been subjected to evaluation. Aims: The primary aim was to investigate if a simulation-based training workshop, where the development of a successful technique for vacuum delivery occurs using a collaborative, problem-solving approach, improves the rate of correct vacuum cup placement. The secondary aim was to determine if the workshop leads to improvement in theoretical knowledge of vacuum delivery. Methods: Participants on three workshops were assessed for their performance in vacuum delivery prior to and following a multimodal training program. Participants included general practitioner obstetricians, obstetric trainees and resident medical officers. Evaluation occurred using a standardised Likert-scaled rating sheet and utilising a diagrammatic representation of cup placement. Results: The participants demonstrated significant improvement (median post-pre score 1, p in the accuracy of cup placement, in a variety of practical core skills and in theoretical knowledge of vacuum delivery. Discussion: Participation in a simulation-based vacuum delivery workshop improves the performance of obstetric trainees and GP obstetricians. Further work is required to evaluate the performance of such training modalities on clinically relevant outcomes.

Bacterial transfer is a concern when sharing food and drink, so to address this concern, this study examined the bacterial transfer onto and into plastic drinking cups. Two experiments were performed to: 1) test bacterial transfer to the rim of a plastic drinking cup, and 2) test residual bacteria in the liquid that was consumed from the cup. Bacteria were enumerated from the cup rim and the water in the cup. The results for both types of transfer showed higher bacterial populations on cups exposed to drinking compared to those where no drinking occurred. However, there was more bacterial transfer to the rim of the plastic cup than the liquid inside the cup.
