Abstract Objective: To provide evidence for selecting an appropriate peripherally inserted central catheter (PICC) insertion technique by comparing the insertion success rate and the incidence of complications with 3 PICC insertion techniques. Methods: We assigned enrolled patients to 3 groups according to the insertion technique selected by the individual patient: Group A, usual insertion technique (traditional, blind insertion); Group B, Modified Seldinger Technique (MST) insertion without ultrasound guidance; and group C, ultrasound-guided MST insertion. We compared the insertion success rate and the incidence of complications among these groups. Results: When comparing these 3 PICC insertion techniques, no significant difference was seen with respect to the insertion success rate and the incidence of catheter malposition (P > 0.05), although a significant difference existed in the incidence of bleeding at the insertion site after the PICC procedure (P < 0.05), with the ultrasound-guided MST insertion technique superior to the other 2 techniques; the incidence of mechanical phlebitis and catheter occlusion during the use of PICC had no significant difference among the 3 groups (P > 0.05); but a significant difference was seen in the incidence of thrombosis and catheter-related infections (P < 0.05), with a lower incidence in the ultrasound-guided MST insertion group than that in the other 2 groups. Conclusions: Ultrasound-guided MST insertion technique may address the problems occurring in patients with poor vascular access during the PICC procedure, whereas the usual insertion technique is the best choice for patients with good vascular access and poor economic status. Therefore, the selection of an appropriate insertion technique should be based on the economic and vascular status of the individual patient in clinical practice.

Background and aim: Malposition of peripherally inserted central catheters placed at the bedside is a well-recognized phenomenon. We report the success rate of the placement of peripherally inserted central catheters with ultrasound guidance for tip positioning and describe the knacks and pitfalls. Materials and methods: We retrospectively reviewed the medical case charts of 954 patients who received peripherally inserted central catheter procedure. Patient clinical data included success rate of puncture, detection rate of tip malposition with ultrasonography, adjustment rate after X-ray, and success rate of peripherally inserted central catheter placement. Results: The success rate of puncture was 100% (954/954). Detection rate of tip malposition with ultrasonography was 82.1% (78/95). The success rate of ultrasound-guided tip navigation was 98.2% (937/954). The success rate of ultrasound-guided tip location was 98.0% (935/954). Adjustment rate after X-ray was 1.79% (17/952). The final success rate of peripherally inserted central catheter placement was 99.8% (952/954). Conclusion: Ultrasound guidance for puncturing and tip positioning is a promising option for the placement of peripherally inserted central catheters. Ultrasound guidance could dispense with radiation exposure and the transfer of patients to the X-ray department.

Objective: To compare the effects of blunt separation combined with early sheath removal and conventional catheterization on the incidence of bleeding, exudation and subcutaneous congestion after peripherally inserted central catheter (PICC). Methods: 250 patients with PICC catheterization in our hospital were selected, including 125 in the control group and 125 in the observation group. The conventional catheterization method was used in the control group: The sheath was removed by scalpel skin expansion and complete tube delivery in place. The observation group used blunt separation combined with early sheath removal. The success rate of one-time sheath delivery, immediate bleeding, 24-hour bleeding and exudation were compared. Results: The success rate of sheath delivery in the observation group was 100%; The amount of immediate blood loss and blood loss 24h after catheterization in observation group was obviously lower than that in the control group, with statistical significance (P < 0.05). There were 6 cases of exudation in the control group and no exudation in the observation group. There was significant difference in the incidence between the two groups (P < 0.05); There were 10 cases of subcutaneous congestion in the control group and 2 cases of subcutaneous congestion in the observation group. There was significant difference in the incidence between the two groups (P < 0.05); Conclusion: Blunt separation combined with early sheath removal can reduce the occurrence of local blood and fluid leakage after PICC catheterization.

Reading and writing performance was observed in 30 adult aphasic patients to determine whether there was a significant difference when stimuli and manual responses were varied in the written form: cursive versus manuscript. Patients were asked to read aloud 10 words written cursively and 10 words written in manuscript form. They were then asked to write on dictation 10 word responses using cursive writing and 10 words using manuscript writing. Number of words correctly read, number of words correctly written, and number of letters correctly written in the proper sequence were tallied for both cursive and manuscript writing tasks for each patient. Results indicated no significant difference in correct response between cursive and manuscript writing style for these aphasic patients as a group; however, it was noted that individual patients varied widely in their success using one writing form over the other. It appeared that since neither writing form showed better facilitation of performance, the writing style used should be determined according to the individual patient’s own preference and best performance.

Abstract Background This study were designed to investigate the usefulness of the videolaryngoscope-guided insertion technique compared with the standard digital technique for the insertion success rate and insertion conditions of the Proseal™ laryngeal mask airway (PLMA). Methods Prospective, one hundred and nineteen patients (ASA I–II, aged 18–65 yr) were randomly divided for PLMA insertion using the videolaryngoscope-guided technique or the standard digital technique. The PLMA was inserted according to the manufacturer’s instructions in the standard digital technique group. The videolaryngoscope-guided technique was performed a C-MAC® videolaryngoscope with D-Blade, under gentle videolaryngoscope guidance, the epiglottis was lifted, and the PLMA was advanced until the tip of the distal cuff reached the oesophagus inlet. The number of insertion attempts, insertion time, oropharyngeal leak pressure, leak volume, fiberoptic bronchoscopic view, peak inspiratory pressure, ease of gastric tube placement, hemodynamic changes, visible blood on PLMA and postoperative airway morbidity were recorded. Results The first-attempt success rate (the primary outcome) was higher in the videolaryngoscope-guided technique than in the standard digital technique (p = 0.029). The effect size values with 95% confidence interval were 0.19 (0.01–0.36) for the first and second attempts, 0.09 (− 0.08–0.27) for the first and third attempts, and not computed for the second and third attempts by the groups, respectively. Conclusion Videolaryngoscope-guided insertion technique can be a help in case of difficult positioning of a PLMA and can improve the PLMA performance in some conditions. We suggest that the videolaryngoscope-guided technique may be a useful technique if the digital technique fails.

Do So

Self-touching gestures can be externally induced by the verbal presentation of anxiety-inducing stimuli and the active discussion of a passage. The frequency of these self-touching gestures appears to be affected by the individual interacting with the topic, the type of discourse (listening or discussing), the type of stimulus (canaries or leeches), and the interaction between the types of discourse and stimulus. This study assessed these variables as well as the sex of the participant and the order of presentation of stimulus type, neither of which were statistically significant. Participants were read two passages, one about a topic (leeches) expected to produce anxiety and the other about a topic (canaries) not expected to do so, and asked to answer questions about the passages. The number of self-touches was counted by an observer in another room. Each participant had both types of discourse (listening and discussing) and both types of stimulus (canaries and leeches). There was no significant difference between the number of self-touches by participants with either the male or female reader. Discussion as a method of discourse was associated with a significantly greater number of self-touches than listening. The interaction between discourse type and stimulus type was also significant. The combination of the anxiety producing stimulus and the active discourse (discussion) produced the highest average number of self-touches.

Calving Performance

An analysis of the growth and calving performance from a crossbreeding program involving four breeds of sires (Angus, Hereford, Friesian and Shorthorn) mated to three breeds of purebred dams (Angus, Hereford and Shorthorn) and three types of crossbred heifers (Angus x Hereford, Friesian x Angus and Friesian x Hereford) during the 1971 and 1972 calving seasons is presented. The performance of the individual breeds of dams and sires were evaluated from the size and growth rate of their progeny at birth, to weaning and post-weaning, as well as from the performance of the dams at calving measured in terms of incidence of difficult calving, percentage of calves dead at birth and twinning rate. Heritability estimates calculated from intra-class correlation of paternal half-sibs were compared from records obtained from purebred calves and from crossbred calves. Crossbred calves were heavier than the purebred calves at birth and grew faster between birth and weaning. After weaning, crossbred heifers grew significantly faster than the purebreds but no significant difference was observed among the steers. There was no significant difference in performance of crossbred calves produced by the purebred and crossbred dams. Calves from the Friesian sires and Friesian cross dams were heavier at birth than calves produced by the other three breeds of beef sires or the beef crossbred dams and they grew faster to weaning. Between weaning and yearling age both the crossbred steers and heifers from the Friesian sires continued to surpass the performance of the beef breeds of sires but there were no significant differences in the performance of three-breed-cross calves of the Friesian cross dams and the Angus x Hereford dams. Heritability estimates of growth rates calculated from data on the performance of the crossbred progeny generally were lower than those calculated from data of the purebred progeny. Higher estimates of heritability were obtained from the data of female progeny than from male progeny for birth weight but the trend was reversed for growth rates between birth to weaning and from weaning to yearling age.

Study Choice

We study choice of profession in three groups of Russian-speaking Jewish families with different occupational distributions of the ancestors. This study continues exploration of the persistence of social status of families over centuries that was initiated in recent years. It was found previously that in some cases professions remain associated with the same surnames for many generations. Here the studied groups are defined by a class of the surname of individuals composing them. The class serves as a label that indicates a professional bias of the ancestors of the individual. One group are the bearers of the class of surnames which were used by rabbinical dynasties. The other group is constituted by occupational surnames, mostly connected to crafts. Finally, the last group are generic Jewish names defined as surnames belonging to neither of the above groups. We use the self-collected database that consists of 858 and 1057 of the first two groups, respectively, and 7471 generic Jewish surnames. The statistics of the database are those of individuals drawn at random from the considered groups. We determine shares of members of the groups working in a given type of occupations together with the confidence interval. The occupational type’s definition agrees with International Standard Classification of Occupations. It is demonstrated that there is a statistically significant difference in the occupational structure of the three groups that holds beyond the uncertainty allowed by 95% confidence interval. We quantify the difference with a numerical measure of the overlap of professional preferences of different groups. We conclude that in our study the occupational bias of different population groups is preserved at least for two centuries that passed since the considered surnames appeared.

Abstract Treatment of serum with folic acid conjugase obtained from fresh chicken pancreas indicated the presence therein of polyglutamyl derivatives of pteroic acid. The polyglutamyl derivatives appeared to belong to a group higher than the triglutamate. Two groups of subjects, one with normal level and the other with low level of unconjugated folate, were studied. In the normal group, the level of unconjugated serum folate varied between 3.2 and 18.0 ng./ml., while that of total folate (unconjugated plus conjugated) varied between 14.0 and 47.0 ng./ml. In the other group, the level of unconjugated folate varied from 2.0 to 2.6 ng./ ml., while that of total folate varied from 14.5 to 31.0 ng./ml. No significant difference, either in the individual values or in their means, was noticed in the two groups of subjects.
