Using software for assessment of restorative work on typodonts in the simulation laboratory may enhance the objective evaluation of student work. The study aimed to evaluate the inter-rater and intra-rater reliability using 3-D scans from the Planmeca Emerald™ intra-oral scanner with Romexis Compare® software for assessing preparations for preformed metal crowns (PMCs). Three operators independently recorded 3-D scans and digitally measured the features of 30 PMC preparations on typodont primary teeth (# 75). Using Romexis Compare® software, preparations were measured from mesial, distal and occlusal aspects. Measurements were repeated after 2 weeks. The intraclass correlation coefficient (ICC) was used to measure the reliability of measurements between operators and within the one operator. For measuring the extent of tooth reduction, there was excellent intra-rater reliability for each operator (ICC 0.96–0.99). The highest inter-rater reliability was for measurements of the occlusal surface (0.946 and 0.956), followed by the mesial surface (0.852 and 0.862) and then the distal surface (0.746 and 0.724). This method was useful and reliable for measuring features of PMC preparation, but with some limitations. Improving the software to provide specific assistance tools would empower greater uptake of this method as an adjunct to traditional visual grading tool in paediatric dentistry preclinical teaching.

We conducted a single-centre, retrospective study for all consecutive cases of recurrent or refractory CDI who underwent FMT from 2013 to 2018. Clinical demographics, outcome, and safety parameters were collected.A total of 24 patients with recurrent or refractory CDI (median age 70 years, interquartile range=45.0-78.3 years; 67% male) were included. Over 80% had been recently hospitalised or were long-term care facility residents. Faecal microbiota transplantation was delivered by feeding tube in 11 (45.8%), oesophagogastroduodenoscopy in eight (33.3%), and colonoscopy in six (25%) of the patients. Resolution of diarrhoea without relapse within 8 weeks was achieved in 21 out of 24 patients (87.5%) after FMT. No deaths occurred within 30 days. The FMT was well tolerated and no serious adverse events attributable to FMT were reported.Our results confirm that FMT is a safe, efficacious, and feasible intervention for patients with refractory or recurrent CDI in Hong Kong. Given the increasing disease burden and the lack of effective alternatives in Hong Kong for difficult-to-treat cases of CDI, we recommend that a territory-wide FMT service be established to address increasing demand for this treatment.

Ectomycorrhizal (ECM) fungi historically were considered poorly represented in Neotropical forests but in the central Guiana Shield substantial areas are dominated by leguminous ECM trees. In the Upper Potaro Basin of Western Guyana, ECM fungi were sampled for 7 years during the rainy seasons of 2000–2008 in three 1-ha plots in primary monodominant forests of the ECM canopy tree Dicymbe corymbosa (Fabaceae subfam. Caesalpinioideae). Over the plot sampling period sporocarps of 126 species of putative or confirmed ECM fungi were recovered. These taxa represented 13 families and 25 genera of primarily Agaricomycetes, but also Ascomycota (Elaphomycetaceae), the majority of which are new to science. Russulaceae contained the most species (20 Russula; 9 Lactarius), followed by Boletaceae (8 genera, 25 spp.), Clavulinaceae (17 Clavulina), and Amanitaceae (16 Amanita). An additional 46 species of ECM fungi were collected in forests of the Upper Potaro Basin outside the study plots between 2000 and 2010, bringing the regional number of ECM species known from sporocarps to 172. This is the first long-term ECM macrofungal dataset from an ECM-dominated Neotropical forest, and sporocarp diversity is comparable to that recorded for ECM-diverse temperate and boreal forests. While a species accumulation curve indicated that ECM sporocarp diversity was not fully recovered inside of the plots, ~80% of the total species were recovered in the first year. Sequence data from ECM roots have confirmed the ECM status of 56 taxa represented by corresponding sporocarp data. However, >50% of ECM fungal species from roots remain undiscovered as sporocarps, leading to a conservative estimate of > 250 ECM species at the Potaro site. Dicymbe forests in Guyana are a hotspot for ECM fungal diversity in the Neotropics.

This paper describes a new ORCA FPGA that focuses on enhancing the speed and gate density of logic systems implemented using high-level logic synthesis. The new family called ORCA 3C/3T, follows the successful ORCA families: 1C, 2C, 2CA and 2TA. The architecture has been designed for efficiently implementing behavioral-level "functions", in addition to regular digital "logic". It includes Look-Up Tables (LUTs), Flip-Flops (FFs) and a PAL-type decoder block grouped in a twin-nibble fashion. The programmable interconnections are designed to provide fast hierarchical connections. To meet the challenge of implementing larger systems, the architecture supports system-level features such as a Programmable Clock Manager (PCM) and a microprocessor interface that can be used during and after the configuration.

A weight control program for junior high school students was developed to change eating, exercise and habit patterns. The course included dietary management, physical activity and behavior modification techniques. Classes were structured to emphasize peer group involvement and daily practical application. The curriculum was compiled in a book for educational personnel. The program was tested as a pilot project with a selected group of eighth grade obese adolescent girls and a comparison group. Immediately after the course, the subjects' percent of overweight had decreased; at a subsequent eight-month follow-up, additional losses were noted. The percent of overweight of the girls in the comparison group remained relatively unchanged. While the program was successful with this particular group of students, several key questions, requiring further study, were defined.

Adolescent pregnancy has long been considered high risk perinatally. It is also a symptom of social disorder. Older studies provided ominous portents of increased risk of toxemia, prematurity, anemia, cephalopelvic disproportion, and perinatal wastage. Studies during the past decade have shown more encouraging data, especially when representing a concerted effort toward this age group. The first 2 years of an intensive and individual approach to gravidas under age 17 are discussed. A total of 135 young women were studied and compared with 100 controls of similar age, treated routinely, and with 100 women of more nearly ideal childbearing age. Perinatal and social data are shown. The implications of the data are discussed in light of other studies. Few, if any, medical differences between the two groups of adolescents and the older women are noted. More important are the social and emotional factors in determining future difficulties.

This article describes a group weight control project with severely obese adolescent girls in a medical setting. Behavior modification and nutritional principles were utilized with peer group interaction. Significant others were included through separate group meetings. This approach produced small amounts of net weight loss for the girls. The drop-outs continued to have a net gain. As a treatment method, this program was more effective for these girls than previous individual clinic contacts had been. When losing weight, the girls tended to use behavior modification techniques more often, and their diets became more adequate nutritionally. Development of group cohesion was tenuous and temporary. Girls who were functioning more independently appeared to do better in weight loss. Disinterested significant others were preferable to nonsupportive ones. A predictive factor was identified, the girls' perception of control. This was measured by the I-E test. Those with a more internalized perception of control were more likely to continue with the program and more likely to lose weight. Because the patient group was small, findings are tentative. However, this program helped to define particular areas that deserve further exploration.
