There is controversy in the literature regarding the indicated retentive mechanism for implant-supported crowns. When adjacent implants are restored, the restoration can be screw retained, cement retained, or a combination of cement and screw retained. Adjacent implant-supported crowns can be restored as individual implant supported crowns or can be splinted. A classification system is proposed when adjacent implants are restored. The classification system describes currently available options to restore adjacent implants. Six types of prosthetic design options are proposed as Class I through Class VI. In Class I design, individual cement-retained crowns are made. In Class II, individual screw-retained crowns are fabricated. Class III involves fabrication of individual screw-retrievable/cement-retained crowns. Class IV prosthetic design involves splinted cement-retained implant crowns. Class V prosthetic design involves splinted screw-retained crowns, and Class VI involves splinted screw-retrievable/cement-retained implant supported crowns.

ABSTRACT The type IV pili of plasmid R64 belonging to the type IVB group are required only for liquid mating. They consist of the major and minor components PilS pilin and PilV adhesin, respectively. PilS pilin is first synthesized as a 22-kDa prepilin from the pilS gene and is then processed to a 19-kDa mature pilin by PilU prepilin peptidase. In a previous genetic analysis, we identified four classes of the pilS mutants (T. Horiuchi and T. Komano, J. Bacteriol. 180:4613-4620, 1998). The products of the class I pilS mutants were not processed by prepilin peptidase; the products of the class II mutants were not secreted; in the class III mutants type IV pili with reduced activities in liquid mating were produced; and in the class IV mutants type IV pili with normal activities were produced. Here, we describe a novel class, class V, of pilS mutants. Mutations in the pilS gene at Gly-56 or Tyr-57 produced type IV pili lacking PilV adhesin, which were inactive in liquid mating. Residues 56 and 57 of PilS pilin are suggested to function as an interface of PilS-PilV interactions.

e15530 Background: CTCs have been widely used in monitoring the efficacy and prognosis of lung cancer. However, CTCs number count alone cannot accurately predict the recurrent disease in patients. In this study, we investigate whether the morphology classification of CTCs could be as a prognostic marker for increased risk of recurrence after surgery. Methods: In this study, 105 lung cancer patients (median age 68y) who underwent surgery were prospectively enrolled in this study. Samples were obtained before, after, and serially up to 24 months after surgery. CTCs were collected and morphology classified by utilizing a CTC test workflow which uses negative enrichment and immunofluorescence methods to capture and identify CTCs from blood sample. Captured CTCs (epithelial type) were screened with a customized imaging analysis pipeline, a cytological profile of each CTC was created, including cell size, shape, fluorescent intensity and texture etc. Results: The CTC detection rate was 78.1% (78 of 105) prior to surgery, and a total of 726 CTCs were enumerated. Median CTC count number was 3. 5 classes of CTCs with distinct morphological features were observed in lung cancer patients’ CTC tests, briefly, CTC class I and class II possessed large nuclei but relatively lower epithelial expression level, CTC class III, IV, V possessed small nuclei but relatively higher epithelial expression level, CTC class III possessed irregular shaped nuclei, CTC class V possessed relatively lower nuclei/cytoplasm ratio. Class III accounted for the highest proportion of captured CTCs III, about 35.5% with Class I 14.8%, Class II 15.3%,Class IV 17.8% and Class 5 16.6%. Postoperative recurrence and metastasis were observed in 16 patients. CTCs positive were found in 14 patients (87.5%). 145 CTCs were collected, Median CTC count number was 3,Cluster III accounted for 47.3%, with Class I 11.8%,Class II 13.3%,Class IV 14.5% and Class V 11.8%; Patients with Cluster 3 dominant were associated with increased risk of local recurrence ( p < 0.05) and distant metastasis ( p < 0.05). Conclusions: Small and irregular nuclei CTC is significant associated with increased risk of recurrence disease. Morphology Classification of circulating tumor cells is feasible in monitoring the recurrence of disease and may potentially identify the patients who may benefit from further therapy.

Introduction: The Pulmonary Embolism Severity Index (PESI) score predicts short-term mortality from pulmonary embolism and low-risk patients suitable for home therapy. However, it is unknown if it is a driver for disposition decisions for emergency department (ED) patients. The primary objective of this study was to define the relationship between disposition decisions and the PESI score in Calgary zone hospitals. Methods: The PESI score was calculated retrospectively for 576 patients presenting to one of four Calgary zone hospitals for pulmonary embolism over the last 2 years. The calculated PESI score allowed the mortality risk of each patient to be estimated for very low risk (Class I, 0-1.6% 30-day mortality rate), low risk (Class II, 1.7-3.5% 30-day mortality rate), intermediate risk (Class III, 3.2-7.1% 30-day mortality rate), high risk (Class IV, 4.0-11.4% 30-day mortality rate), and very high risk (Class V, 10.0- 24.5% 30- day mortality rate). The patients were grouped based on being admitted to the hospital for inpatient care, or discharged for outpatient care. Descriptive statistics were used to describe the data. Results: Of the 576 patients, 317 (55%) were discharged and 259 (45%) were admitted to the hospital for inpatient care. Among admitted patients, 20.5% were considered Class I, 29.3% were Class II, 24.3% were Class III, 17.6% were Class IV, and 8.1% were Class V. Among discharged patients, 53.9 % were Class I, 25.6% were Class II, 15.5% were Class III, 4.4% were Class IV, and 0.6% were Class V. Of the 25 very high-risk (Class V) patients, 2 (8.0%) were discharged from the ED and treated as outpatients. Of the 223 very low risk (Class I) patients, 171 (76.7%) were discharged and 52 (23.3%) were admitted to hospital. Conclusion: A significant percentage of pulmonary embolism patients admitted to Calgary Zone hospital wards are PESI low risk (29.3%) or very low risk (20.5%). Implementation of a PESI score-based disposition pathway could improve the safety, cost-effectiveness and quality of ED disposition decisions for PE.

AbstractThis paper begins with a discussion concerning the development of the term "atlatl weight" in archaeological literature. It then proceeds to analyze in detail data relative to 60 atlatl weights from 39 locations on the Plains area of Alberta, Saskatchewan, Montana, Wyoming, Colorado, North Dakota, South Dakota, Nebraska, Kansas, and Iowa. Although most of the specimens are surface finds, a number are from systematically excavated, radiocarbon-dated occupations.Differentiated primarily on their general shapes, five groups of atlatl weights seem apparent: Class I, loaf-shaped; Class II, end-ridged; Class III, long ellipsoidal; Class IV, zoomorphic; and a miscellaneous category.Available evidence suggests that atlatl weights were being made, in the area under consideration, from about 2500 B.C. until A.D. 800.

Background: Heart Failure (HF) is a major public health burden worldwide. Approximately 5 million Americans, 0.4–2% of the general European population and over 23 million people worldwide are living with heart failure. Like few other chronic disease, low serum albumin is common in patients with heart failure (HF). However, very few studies evaluated the outcome of albumin infusion in different stages of HF. Therefore, the objective of this study is to assess the outcome of albumin infusion in heart failure patients. Methods: It was a cross-sectional study. A total of 50 cases of chronic heart failure with reduced ejection fraction and NYHA class III or IV with serum albumin level <2.5g/dl who were admitted in CCUwere selected by purposive sampling, from September 2017 to August 2018. 100ml of 20% albumin was infused and serum albumin was measured after 3 days. Then the patients were divided into two groups, Patients who failed to attain serum albumin of 3g/dl(Group A) or Patients who attained serum albumin of ≥3g/dl (Group B). Analysis and comparison for symptomatic improvement of heart failure by NHYA classification and LVEF was done at 10th day after infusion between group A and B. Result: Among the 50 patients, mean age of patients was 53.64 ± 13.44 years (age range: 26-84 years) with a male-female ratio of 3:2 (60%-male vs 40%- female). Majority patients were previously re-admitted at least two times (40%), 28% were re-admitted once, 16% were re-admitted three times and 4% were re-admitted for four times. Of all, 56% patients presented NYHA class IV and AHA stage D heart failure (56%) and 44% patients presented with NYHA class III and AHA stage C. At day 10 follow up following albumin infusion, overall frequency of following ten days of albumin therapy, in group B, 8 patients (72.7%) among Class III improved to Class I and 3 patients (27.3%) improved to class II. Also, 7 patients (50%), 5 patients (35.7%) and 2 patients (14.3%) among class IV improved to respectively class I, class II and class III. In group A, 3 patients (27.3%) among class III improve to class II and 8 patients (72.7%) remain in class III. Also, 2 patients (14.3%), 5 Patients (35.7%) and 7 patients (50%) among class IV improve to respectively class I, class II and class III. Moreover, statistically significant improvement was noted in ejection fraction of patents irrespective of initial class of heart failure (p<0.001) in group B patients compare to group A (p<0.09). Conclusion: In this study, the improvement of heart failure was more in patients who attained albumin level of ≥3g/dl.Therefore, in can be concluded that albumin infusion improves both subjective and objective improvement of patients with heart failure.

Currently, the effectiveness of medical and surgical treatment of focal forms does not exceed 75 %. In cases when control over attacks by means of conservative therapy is not possible, and resection indications for surgical intervention are not present, the use of vagus nerve electrical stimulation is recommended.The study objective is to evaluate the effectiveness of vagus nerve electrical stimulation in treatment of drug-resistant epilepsy depending on the type of the disease and patient age.Materials and methods. Retrospective analysis of treatment results of 45 patients (22 children between 2 and 17 years of age (mean age 12.3 years) and 23 adults between 18 and 62 years of age (mean age 29.4 years)) with drug-resistant epilepsy was performed. All patients were implanted with electric stimulator of the left vagus nerve. Control examination was carried out 1 year after surgery, the evaluation method – McHugh scale.Results. In the child group, the results corresponded to class I per the McHugh sale in 30 % of cases, class II – in 26 %; class III – in 26 %, class IV – in 18 %. In the adult group, the results corresponded to class I in 18 % of cases, class II – in 19 %, class III – in 37 %, class IV – in 26 %. In patients with duration of the disease >10 years, results of electrical stimulation were good or excellent in 44 % of cases, for patients with duration between 5 and 10 years – in 40 % of cases, with duration <5 years – in 60 %, but due to small sample size the results are not statistically significant. In patients with simple partial seizures, the treatment was effective in 4 (54 %) of 7 cases, in patients with generalized seizures – in 16 (42.8 %) of 38 cases. The best results were also obtained for interventions in patients between 10 and 15 years of age.Conclusion. Children respond better to vagus nerve electrical stimulation; in the adult age group, it is noted that patients with aura have a better response to therapy with vagus nerve electrical stimulation; smaller epianamnesis is associated with better efficiency; patients with symptomatic epilepsy have a worse response to therapy, than patients with cryptogenic epilepsy; there were no gender differences in the effectiveness of vagus nerve electrical stimulation.

Forty zebrafish mutants with localized or general neural degeneration are described. The onset and duration of degeneration and the distribution of ectopically dying cells are specific characteristics of each mutant. Mutants are classified into four groups by these parameters. Class I: late focal neural degeneration mutants. These 18 mutants have restricted cell death mainly in the tectum and the dorsal hindbrain after 36 hours. The degeneration does not spread and disappears at later stages of development. Class II: early focal neural degeneration mutants. Ten mutants in this class exhibit transient restricted degeneration affecting mainly the diencephalon, the hindbrain and the spinal cord at 20 hours. The midbrain is less affected. The degeneration shifts to the dorsal diencephalon and the tectum at 36 hours. Class III: late spreading neural degeneration mutants. The 8 mutants in this class display a degeneration that is first seen in the tectum and subsequently spreads throughout the nervous system from 36 hours on. Class IV: early general neural degeneration mutants. This class of four mutants already shows overall cell degeneration in the nervous system at the 15-somite stage. Three of the class I mutants show a change in the pattern of gene expression in the anlage of a brain structure prior to the onset of degeneration. These results suggest that focal cell death may be a useful clue for the detection of early patterning defects of the vertebrate nervous system in regions devoid of visible landmarks.
