To assess the validation of a novel control selection design by comparing the consistency between the new design and a routine design in a large case-control study that was incorporated into a nationwide mortality survey in China. A nationwide mortality study was conducted during 1989-1991. Surviving spouses or other relatives of all adults who died during 1986-1988 provided detailed information about their own as well as the deceased person's smoking history. In this study, 130,079 males who died of various smoking-related cancers at age 35 or over were taken as cases, while 103,248 male surviving spouses (same age range with cases) of women who died during the same period and 49,331 males who died from causes other than those related to smoking were used as control group 1 and control group 2, respectively. Consistency in the results when comparing cases with each of the control groups was assessed. Consistency in the results was observed in the analyses using different control groups although cancer deaths varied with region and age. Equivalence could be ascertained using a 15% criterion in most cancer deaths which had high death rates in urban areas, but they were uncertain for most cancers in rural areas irrespective of whether the hypothesis testing showed significant differences or not. Sex-matched living spouse control design as an alternative control selection for a case-control study is valid and feasible, and the basic principles of the equivalence study are also supported by epidemiological survey data.

Consanguineous unions occur in all populations around the world. Couples related as second cousins or closer have been observed with deleterious effect. Among the clinical effects of parental consanguinity, the incidence of offspring with congenital malformations (CM) increases approximately two-fold. A hospital database of neonates with CM was searched to select neonates with parental consanguinity and two control groups. One control group consisted of healthy neonates and the other control group consisted of neonates with CM but without parental consanguinity. Both control groups consisted of the first neonate of the same sex to be born after a consanguineous neonate with CM. Family, sociodemographic and anthropometric variables, as well as the severity of the malformations, were compared between the two groups with CM. Neonates with CM were grouped into five categories: Major multiple CM, minor multiple CM, isolated major CM, isolated minor CM, and specific diseases. The indigenous Mayan subpopulation was also analyzed. Among 1117 neonates with CM, parental consanguinity was found in 21. Parental consanguinity was also found in 8 neonates in the group of healthy controls (OR 2.4 [1.05-5.95]). The most common form of consanguinity was between second cousins and was more frequent in the Mayan subpopulation. Major multiple CM were more frequent among consanguineous than among nonconsanguineous couples. No association was found between the severity of CM and the degree of relationship. The prevalence of consanguinity found in neonates with CM and healthy controls (1.9 % and 0.8 %) was similar to that found in other Latin populations. A higher prevalence was found in the Mayan population. Mayor multiple CM were more frequent among the neonates of consanguineous than among nonconsanguineous couples.

This study characterizes hypnagogic hallucinations reported during a polygraphically recorded 90-min daytime nap following or preceding practice of the computer game Tetris. In the experimental group (N = 16), participants played Tetris in the morning for 2 h during three consecutive days, while in a first control group (N = 13, controlling the effect of experience) participants did not play any game, and in a second control group (N = 14, controlling the effect of anticipation) participants played Tetris after the nap. During afternoon naps, participants were repetitively awakened 15, 45, 75, 120 or 180 s after the onset of S1, and were asked to report their mental content. Reports content was scored by three judges (inter-rater reliability 85%). In the experimental group, 48 out of 485 (10%) sleep-onset reports were Tetris-related. They mostly consisted of images and sounds with very little emotional content. They exactly reproduced Tetris elements or mixed them with other mnemonic components. By contrast, in the first control group, only one report out of 107 was scored as Tetris-related (1%), and in the second control group only three reports out of 112 were scored as Tetris-related (3%; between-groups comparison; P = 0.006). Hypnagogic hallucinations were more consistently induced by experience than by anticipation (P = 0.039), and they were predominantly observed during the transition of wakefulness to sleep. The observed attributes of experience-related hypnagogic hallucinations are consistent with the particular organization of regional brain activity at sleep onset, characterized by high activity in sensory cortices and in the default-mode network. © 2011 European Sleep Research Society.

Instructional multimedia: An investigation of student and instructor attitudes and student study behavior

PubMed Central

2011-01-01

Background Educators in allied health and medical education programs utilize instructional multimedia to facilitate psychomotor skill acquisition in students. This study examines the effects of instructional multimedia on student and instructor attitudes and student study behavior. Methods Subjects consisted of 45 student physical therapists from two universities. Two skill sets were taught during the course of the study. Skill set one consisted of knee examination techniques and skill set two consisted of ankle/foot examination techniques. For each skill set, subjects were randomly assigned to either a control group or an experimental group. The control group was taught with live demonstration of the examination skills, while the experimental group was taught using multimedia. A cross-over design was utilized so that subjects in the control group for skill set one served as the experimental group for skill set two, and vice versa. During the last week of the study, students and instructors completed written questionnaires to assess attitude toward teaching methods, and students answered questions regarding study behavior. Results There were no differences between the two instructional groups in attitudes, but students in the experimental group for skill set two reported greater study time alone compared to other groups. Conclusions Multimedia provides an efficient method to teach psychomotor skills to students entering the health professions. Both students and instructors identified advantages and disadvantages for both instructional techniques. Reponses relative to instructional multimedia emphasized efficiency, processing level, autonomy, and detail of instruction compared to live presentation. Students and instructors identified conflicting views of instructional detail and control of the content. PMID:21693058

Anger plays a major role in psychodermatological diseases. Researchers have reported that anger and other psychological factors play a role in the etiology of chronic urticaria. This study aimed to examine symptoms of anger, anger-related behavioral patterns, thoughts associated with anger, situations that cause anger and experiences of interpersonal anger in patients with chronic spontaneous urticaria (CSU). The authors hypothesized that patients with CSU react to more situations with anger and experience more anger symptoms as compared to alopecia areata (AA) patients and healthy controls. The cohort study population consisted of literate adult patients aged <65 years that were diagnosed with CSU at the outpatient dermatology clinics of Başkent and Gazi University, Ankara, Turkey, between September 2011 and October 2012. The first control group included individuals without any physical or mental disorders and the second one included literate adult patients diagnosed with AA. The patients and controls were matched according to age, gender, and level of education. A sociodemographic data form, and the Hospital Anxiety and Depression Scale and Multi-Dimensional Anger Inventory were administered to the participants. Data were analyzed using SPSS v.17.0 for Windows. The primary outcome was to determine whether there was a relationship between anger and CSU. The CSU group consisted of 30 participants; AA group consisted of 30 participants; and the healthy group consisted of 39 participants. Anxiety and depression scores in the CSU group were significantly higher than those in the healthy control group. Symptoms of anger, situations that cause anger, and thoughts associated with anger were significantly more common in the CSU group compared to AA group and healthy group. More of the CSU patients were observed to respond with excessive anger to most situations, to have high levels of anxiety anger and passive aggressive interpersonal relationships.

Effect of Audiovisual Distraction on Distress and Oxygenation Status in Children Receiving Aerosol Therapy.

PubMed

Shinta Devi, Ni Luh Putu; Nurhaeni, Nani; Hayati, Happy

Aerosol therapy, a treatment for children with disorders of the respiratory system, often causes distress, especially in young children. Distress during aerosol therapy can decrease the effectiveness of the treatment. This study aimed to determine the effect of audiovisual distraction on distress levels and oxygenation status (measured by oxygen saturation and respiratory frequency) in children who receive aerosol therapy for disorders of the respiratory system. A quasi-experimental design was employed, specifically a non-equivalent control group, pre-test-post-test design. The study sample consisted of 38 children who were divided into 2 groups (control and intervention), each group consisting of 19 children. The results of this study showed that there were significant differences in distress scores between the control group and the intervention group (p = .0001). There were also significant differences in the mean value changes in oxygenation status before and after intervention between the control and intervention groups. These findings could be used to prevent distress and increase oxygenation status in children who receive aerosol therapy.

The purpose of the present study was to validate the Mandarin version of the International Prostate Symptom Score (Mand-IPSS) in a Malaysian population. The validity and reliability were studied in patients with lower urinary tract symptoms (LUTS; benign prostatic hyperplasia [BPH] group) and without LUTS (control group). Test-retest methodology was used to assess the reliability while Cronbach alpha was used to assess the internal consistency. Sensitivity to change was used to express the effect size index in the preintervention versus post-intervention score in patients with LUTS who underwent transurethral resection of the prostate. For the control group and BPH group, the internal consistency was excellent and a high degree of internal consistency was observed for all seven items (Cronbach alpha = 0.86-0.98 and 0.90-0.98, respectively). Test-retest correlation coefficients for all items were highly significant. Intraclass correlation coefficient (ICC) was high for the control (ICC = 0.93-0.99) and BPH group (ICC = 0.91-0.99). The sensitivity and specificity showed a high degree of sensitivity and specificity to the effects of treatment. A high degree of significance between baseline and post-treatment scores was observed across all seven items in the BPH group but not in the control group. The Mand-IPSS is a suitable, reliable, valid and sensitive instrument to measure clinical change in the Malaysian population.

ABSTRACT Introduction. Clinical researches have shown an increased bone disintegration and lower bone mass in patients with calcium urolithiasis. Goal. The goal of our research was to establish the incidence of osteoporosis in adult patients with calcium urolithiasis, on the basis of measuring mineral bone density, using DEXA method, with a special reflection on age subgroups. Material and methods. Clinical research was prospective and it was implemented at the University Clinical Center of Banja Luka, at the Clinic for Endocrinology, Diabetes and Metabolic Diseases and at the Urology Clinic. Material in this research consisted of patients divided in two groups, a working and a control group. One hundred and twenty (120) patients were included in both these groups, divided in three age subgroups: 20-40, 40-60 and over 60. The working group consisted of the patients with calcium urolithiasis and the control group consisted of patients without calcium urolithiasis. Establishing of mineral bone density at L2-L4 of lumbal spine vertebrae and hip was done for the patients in both these groups, using DEXA method. Results. Analysis of mineral bone density using DEXA method in patients in age groups of working and control groups, as well as in the total sample of working and control groups, have shown that the patients of the working group, over 60, had a decreased mineral bone density (30% of osteopenia and 15% osteoporosis) significantly more expressed when compared to the other two age groups (12.5% in the subgroup 20-40 and 17.5% in the subgroup 40-60), which presents a statistically significant difference (p<0.05). In the control group, when taking into account age groups, osteopenia and osteoporosis were marked in 37.5% and 2.5% in the group of patients over 60, whereas in the youngest population, 5% of osteopenia was found, which presents a statistically significant difference (p<0.05). When observing the total sample of working and control group, there was a statistically significant difference in the working and control group (p<0.01); incidence of osteoporosis in the working group amounted to 7.5% and in the control group it was 0.8%. Conclusion. Urolithiasis and osteoporosis are two multifactorial diseases which are evidently reciprocal. This is why we suggest that educating the population about the risk factors for occurrence of these diseases as well as preventive measures that may contribute to their decrease should begin as early as possible.

The aim of this study was to explore the circadian blood pressure (BP) rhythm using ambulatory BP monitoring (ABPM) in normotensive children with a family history of essential hypertension. Group 1 consisted of children with hypertensive mothers and/or fathers (n = 20), Group 2 consisted of children with hypertensive grandparents (n = 20), and Group 3 consisted of children with normotensive parents (n = 20). All participating children underwent a 24-h ABPM and echocardiography. Significantly higher systolic burden was found in children with hypertensive parents (p < 0.05) and grandparents (p < 0.05) compared to controls. Ambulatory BP measurements had a higher daytime systolic BP in Group 1 compared to controls (p < 0.05). While left ventricular (LV) posterior wall thickness was similar in Group 1 and Group 2, it was significantly higher in both of these groups compared to the controls. The LV mass index (LVMI) was significantly higher in Group 1 than in controls (p < 0.05). However, diastolic BP was significantly higher in dippers compared to non-dippers (p < 0.05). LV posterior wall thickness, interventricular septum thickness and LVMI were significantly higher among non-dippers compared to dippers (p < 0.05). In children with a family history of hypertension, a positive correlation between nocturnal systolic BP and LVMI was found, and increasing nocturnal BP values were associated with increasing LVMI (p < 0.01). In children with a family history of hypertension, target-organ damage may precede the clinical detection of hypertension, and in those with a nocturnal non-dipper status, a more marked effect on LVMI may occur.

Twelve martian meteorites that have been re- covered so far are classified into five groups (basalt, lherzolite, clinopyroxenite, dunite, and orthopyroxenite) mainly from petrology and chemistry. Among them, the dunite and orthopyroxenite groups consist of only one meteorite each (dunite: Chassigny, orthopyroxenite: ALH 84001). The basalt group is the largest group and consists of four meteorites (Shergotty, Zagani, EETA 79001, and QUE 94201). The lherzolitic and clinopyroxenitic groups include three meteorites each (Lherzolite: ALH 77005, LEW 88516, and Y793605, clinopyroxenite: Nakhla, Governador Valadares, and Lafayette). These meteorites within each group are generally similar to the others, but none of them is paired with the others. In this abstract, we discuss the major factors that controlled mineralogical similarities and differences of basaltic, lherzolitic, and clinopyroxenitic meteorites within each group. This may help in understanding their petrogenesis and original locations on Mars in general.

Pulmonary Hypertension Among End-Stage Renal Failure Patients Following Hemodialysis Access Thrombectomy

Harp, Richard J.; Stavropoulos, S. William; Wasserstein, Alan G.

Purpose: Percutaneous hemodialysis thrombectomy causes subclinical pulmonary emboli without short-term clinical consequence; the long-term effects on the pulmonary arterial vasculature are unknown. We compared the prevalence of pulmonary hypertension between patients who underwent one or more hemodialysis access thrombectomy procedures with controls without prior thrombectomy.Methods: A retrospective case-control study was performed. Cases (n = 88) had undergone one or more hemodialysis graft thrombectomy procedures, with subsequent echocardiography during routine investigation of comorbid cardiovascular disease. Cases were compared with controls without end-stage renal disease (ESRD) (n = 100, group 1), and controls with ESRD but no prior thrombectomy procedures (n =more » 117, group 2). The presence and velocity of tricuspid regurgitation on echocardiography was used to determine the prevalence and grade of pulmonary hypertension; these were compared between cases and controls using the chi-square test and logistic regression.Results: The prevalence of pulmonary hypertension among cases was 52% (46/88), consisting of mild, moderate and severe in 26% (n = 23), 10% (n = 9) and 16% (n = 14), respectively. Prevalence of pulmonary hypertension among group 1 controls was 26% (26/100), consisting of mild, moderate and severe pulmonary hypertension in 14%, 5% and 7%, respectively. Cases had 2.7 times greater odds of having pulmonary hypertension than group 1 controls (p = 0.002). The prevalence of pulmonary hypertension among group 2 controls was 42% (49/117), consisting of mild, moderate and severe pulmonary arterial hypertension in 25% (n = 49), 10% (n = 12) and 4% (n = 5), respectively. Cases were slightly more likely to have pulmonary hypertension than group 2 controls (OR = 1.5), although this failed to reach statistical significance (p = 0.14).Conclusion: Prior hemodialysis access thrombectomy does not appear to be a risk factor for pulmonary arterial hypertension. Patients with ESRD are more likely to have pulmonary hypertension.« less

Attention control groups are often used in research testing the efficacy of psychosocial and behavioural interventions in order to control for placebo effects. The authors conducted a descriptive qualitative study to investigate how participants viewed their experiences in attention control and experimental intervention groups following a randomized controlled trial for women with fibromyalgia syndrome. Moderately structured interviews were conducted with 18 women (12 from the experimental intervention group and 6 from the attention control group). Members of the control group reported some benefits but few behavioural changes as a result of participating in the RCT, and some participants expressed disappointment at not receiving the intervention. Perceptions of changes in attitudes towards fibromyalgia syndrome and behaviours reported by the intervention group appear to be consistent with the theory underlying the intervention. Possible placebo effects identified in both groups include negative and positive social interactions with other participants.

This multicenter phase III study (NCT01340937) evaluated the consistency of immune responses to 3 separate lots of diphtheria-tetanus toxoids-acellular pertussis 5, inactivated poliovirus vaccine, Haemophilus influenzae type b, and hepatitis B (DTaP5-IPV-Hib-HepB), an investigational hexavalent vaccine (HV). Healthy infants were randomized (2:2:2:1) to receive HV or Pentacel (Control). Groups 1, 2 and 3 received HV at 2, 4 and 6 months, and Control at 15 months. Group 4 received Control at 2, 4, 6 and 15 months, plus Recombivax HB (HepB) at 2 and 6 months. Concomitant Prevnar 13 was given to all groups at 2, 4, 6 and 15 months; pentavalent rotavirus vaccine (RV5) was given to all groups at 2, 4 and 6 months. Blood specimens (3-5 mL) were collected immediately before administration of dose 1, postdose 3, immediately before toddler dose, and after toddler dose. Adverse events were recorded after each vaccination. The 3 manufacturing lots of HV induced consistent antibody responses to all antigens. Immunogenicity of HV was noninferior to Control for all antibodies, except for pertussis filamentous hemagglutinin geometric mean concentration postdose 3, and pertussis pertactin (PRN) geometric mean concentration after toddler dose. Postdose 3 immunogenicity of concomitantly administered Prevnar 13 was generally similar (except for serotype 6B) when given with HV or Control. Adverse events of HV were similar to Control, except for a higher rate of fever ≥38.0°C [49.2% vs. 35.4%, estimated difference 13.7% (8.4, 18.8)]. HV demonstrated lot-to-lot manufacturing consistency; safety and immunogenicity were comparable with the licensed vaccines. HV provides a new combination vaccine option within the US 2-month, 4-month and 6-month vaccine series.

Specific problems with time and timing that affect daily routines, homework, school work, and social relations have been recognized in children with ADHD. The primary treatments for children with ADHD do not specifically focus on time-related difficulties. The aim of this randomized controlled study (RCT) was to investigate how multimodal interventions, consisting of training in time-processing ability (TPA) and compensation with time-assistive devices (TAD), affect TPA and daily time management (DTM) in children with ADHD and time difficulties, compared with only educational intervention. Thirty-eight children on stable medication for ADHD in the 9-15-year age range were randomly allocated to an intervention or a control group. The children's TPA was measured with a structured assessment (KaTid), and the children's DTM was rated by a parent questionnaire (Time-Parent scale) and by children's self-reporting (Time-Self-rating). The intervention consisted of time-skill training and compensation with TAD. Data were analysed for differences in TPA and in DTM between the control and intervention groups in the 24-week follow-up. Children in the intervention group increased their TPA significantly (p = 0.019) more compared to the control group. The largest increase was in orientation to time. In addition, the parents in the intervention group rated their children's DTM as significantly (p = 0.01) improved compared with the parents in the control group. According to the children, their DTM was not significantly changed. In conclusion, a multimodal intervention consisting of time-skill training and TAD improved TPA and DTM in children with ADHD aged 9-15 years.

Background & objectives: Randomized controlled trials in developed countries have reported benefits of Lactobacillus GG (LGG) in the treatment of acute watery diarrhoea, but there is paucity of such data from India. The study was aimed to evaluate the efficacy and safety of Lactobacillus GG in the treatment of acute diarrhoea in children from a semi-urban city in north India. Methods: In this open labelled, randomized controlled trial 200 children with acute watery diarrhoea, aged between 6 months to 5 years visiting outpatient department and emergency room of a teaching hospital in north India were enrolled. The children were randomized into receiving either Lactobacillus GG in dose of 10 billion cfu/day for five days or no probiotic medication in addition to standard WHO management of diarrhoea. Primary outcomes were duration of diarrhoea and time to change in consistency of stools. Results: Median (inter quartile range) duration of diarrhoea was significantly shorter in children in LGG group [60 (54-72) h vs. 78 (72-90) h; P<0.001]. Also, there was faster improvement in stool consistency in children receiving Lactobacillus GG than control group [36 (30-36) h vs. 42 (36-48) h; P<0.001]. There was significant reduction in average number of stools per day in LGG group (P<0.001) compared to the control group. These benefits were seen irrespective of rotavirus positivity in stool tests. Interpretation & conclusions: Our results showed that the use of Lactobacillus GG in children with acute diarrhoea resulted in shorter duration and faster improvement in stool consistency as compared to the control group.

The purpose of this study was to investigate if adolescents with cleft lip, or palate, or both (CLP), have an altered self-concept, and to assess their degree of introversion, compared with a control group. The CLP group consisted of 55 adolescents (aged 17-20 years) and the control group consisted of 31 adolescents (16-19 years). The Tennessee Self Concept Scale (TSCS) was used to measure the subjects' self-concept, while the Eysenck Personality Questionnaire Inventory (EPQ-I) was used to measure introversion. The results indicate that those with CLP have a normal or even a high self-concept, and no signs of introversion.

To evaluate the effectiveness of school-based reproductive health education for adolescent girls on the reproductive knowledge level of the girls. This research was carried out as a quasi-experimental study at two vocational girls high schools, one of which was used as the study school and the other as the control school. The study group (97 students) consisted of three classes representing every grade. The control group consisted of students selected likewise (92 students). Reproductive health education was given to students in the study group for 10 weeks; the control group was not subjected to any educational program. The impact of the program was evaluated with reproductive health knowledge test designed for this study. A pretest evaluated baseline knowledge, and a posttest measured the gain in knowledge. Baseline knowledge score of students in study and control group were similar and low (p > 0.05). We found that the reproductive health knowledge level of students in the study group increased significantly after the program of education. Post-test knowledge scores (75.03 +/- 13.82) of the students in the study group were higher than those of the control group (36.65 +/- 14.17). The results showed students' low baseline knowledge and a good ability to learn. A school-based reproductive health education is needed to promote knowledge and prevention in reproductive health among teenagers.

Experts advocate educational programs addressing misinformation regarding donation decisions to increase the potential donor pool. However, few researchers have measured outcomes with nursing students. The purpose of this study was to evaluate the impact of an educational intervention on nursing students' knowledge, attitudes, registering as an organ donor, and family discussions. This quasi-experimental study used a pretest-posttest design with a control group. The research group consisted of 42 volunteers and the control group consisted of 73 volunteers. The written survey included 15 true-false knowledge items and 8 Likert items asking about attitude toward donation, registering as an organ donor, and family discussion. Normally distributed data showed no significant differences between groups on the pretest. The research group had no change in knowledge level 3 months later, but the control group had a significantly decreased knowledge level at that point. More members of the research group than the control group registered as organ donors after the intervention (χ2 = 4.5, P= .03). The control group had no change in registering as an organ donor between the pretest and posttest. Family discussions did not differ significantly from pretest to posttest in either group. One lecture/laboratory experience did make a difference in registering as an organ donor but not in discussing the decision with family members. Students can learn about organ donation from more than one specific class. Recommendations for educators and future research are provided.

Objective: An evaluation is made of pain, swelling and peri-implant attached mucosal width after implant-based rehabilitation involving guided surgery and a modification of the technique with the raising of a semicircular miniflap, in single and partial replacements. Study design: A case-control study was carried out. The study group consisted of 12 patients with the placement of 19 implants using a guided surgery and miniflap technique. The control group consisted of 12 patients with the placement of 22 implants using the conventional technique. Each patient scored postoperative swelling and pain by means of a visual analog scale (VAS). Attached vestibular mucosa width was evaluated 12 weeks after implant placement. Results: Twelve operations were carried out in each group. Immediate aesthetics were established for all implants of the study group. One implant failed in each group. Maximum pain was recorded after 6 hours in both groups (mean VAS score 4 and 4.9 in the study and control group, respectively). Maximum swelling was recorded after 24 hours (mean VAS score 2.5) in the study group and on the second day (mean VAS score 3.4) in the control group. The mean attached vestibular mucosa width was 2.9 mm in the study group and 3.2 mm in the control group. Conclusion: In this preliminary study, guided implant surgery with a semicircular miniflap in single and partial replacements resulted in slightly less postoperative pain and swelling than with the conventional implant technique. The attached vestibular mucosa width was greater in the control group, though the differences were very small. Key words:Guided surgery, flapless surgery, miniflap, peri-implant mucosa.

The relationship between the level of serum angiotensin converting enzyme (SACE) and the total body granuloma load in patients with sarcoidosis was studied in two groups using SACE levels and total body gallium67 scans. The study group consisted of 22 patients with SACE levels greater than or equal to 100 U/ml (EH-SACE group) and the control group consisted of 24 patients consecutively diagnosed to have sarcoidosis in a one year period with SACE level of less than 80 U/ml. The average number of organs involved in the EH-SACE group was 3.9 +/- 1 compared to 2.3 +/- 1 in the control group (p less than 0.0001). The incidence of extra pulmonary organ involvement in the EH-SACE group was 2.2 +/- 1 organs compared to 1.0 + 0.8 in the control group (p less than 0.0002). The SACE level was correlated with the number of organs involved for all patients with sarcoidosis (r = .55; p less than .0001). Following corticosteroid therapy for 39 +/- 41 weeks the SACE dropped to 64 +/- 45 units in the EH-SACE group. But it took only 13 +/- 10 weeks to normalize the SACE level to 27 +/- 9 units in the control group. The EH-SACE group patients were followed for 114 +/- 64 weeks and 73% of them still have active sarcoidosis requiring repeated cycles of corticosteroid therapy, while after 42 +/- 23 weeks of follow up only 10% of patients from the control group were still on therapy.(ABSTRACT TRUNCATED AT 250 WORDS)

AIM: To increase inspiratory muscle strength and improve the quality of life of candidates for liver transplantation. METHODS: Twenty-three candidates for liver transplantation participated in the control group and 14 made up the intervention group. The control group consisted of 18 men and 5 women, body mass index (BMI) 27.3 ± 4.5 kg/m2 and Model for End-Stage Liver Disease (MELD) 18.2 ± 6.1. The intervention group consisted of 11 men and 3 women, BMI 28.6 ± 5.4 kg/m2 and MELD 18 ± 4.5. The presence or absence of ascites was identified in the first patient evaluation and after three months. We evaluated maximal inspiratory pressure (MIP) and maximal expiratory pressure, spirometry, root mean square (RMS) of diaphragm and rectus abdominis, and the quality of life. The exercises were performed daily by patients at home for three months and were supervised at distance monthly. The manual consisted of diaphragmatic breathing exercises, diaphragmatic isometric exercise, Threshold IMT®, lifting upper limbs with a bat and strengthening the abdomen. RESULTS: There was significant difference (P = 0.01) between the first (initial) and the third month (final) MIP in the control group and in the intervention group, but there was no difference (P = 0.45) between the groups. The RMS of the diaphragm was lower (P = 0.001) and the functional capacity was higher (P = 0.006) in the intervention group compared to the control. The general health and mental health domains received higher scores after three months in the control group (P = 0.01) and the intervention group (P = 0.004), but there was no significant difference between them. The comparison between the presence of initial ascites with the presence of ascites was performed after three months in the control group (P = 0.083) and intervention group (P = 0.31). There was no significant difference, in relation to the presence of ascites after three months between groups (P = 0.21). In the intervention group, patients with ascites at the end of the time period had decreased scores on the social aspects SF-36 domain (P = 0.023) compared to those who had no ascites. CONCLUSION: The proposed exercises provide an increase in the inspiratory muscle strength and improve functional capacity, consequently bettering the quality of life of liver disease patients.

The aim of this study was to determine the effect of combination therapy consisting of acupuncture and traditional herbal medicine (Kampo medicine) for reducing the incidence rate of delirium in patients with cardiovascular (CV) disease in ICUs. Twenty-nine patients who had been urgently admitted to the ICU in the control period were treated with conventional intensive care. Thirty patients in the treatment period received conventional therapy plus a combination therapy consisting of acupuncture and herbal medicine. Acupuncture treatment was performed once a day, and the herbal formula was administered orally three times a day during the first week of the ICU stay. The standard acupuncture points were GV20, Ex-HN3, HT7, LI4, Liv3, and KI3, and the main herbal preparation was Kamikihito. The incident rates of delirium, assessed using the confusion assessment method for ICU, in the treatment and control period were compared. The incidence rate of delirium was significantly lower in the treatment group than in the control group (6.6% vs. 37.9%, [Formula: see text]). Moreover, sedative drugs and non-pharmacological approaches against aggressive behavior of patients who were delirious were used less in the treatment group than in the control group. No serious adverse events were observed in the treatment group. Combination therapy consisting of acupuncture and herbal medicine was found to be effective in lowering the incidence of delirium in patients with CV disease in ICUs. Further studies with a large sample size and parallel randomized controlled design would be required to establish the effects of this therapy.

Hyperprolactinemia could be one of possible causes of bone loss. The reason is thought to be connected with hypogonadism due to PRL excess and the role of other hormones like PTH and PTH-rP. There is no data on the influence of PTH fractions (CAP and CIP) on bone turnover and density in hyperprolactinemia. The aim of the study was to assess the influence of PTH and its fractions on bone metabolism in hyperprolactinemia of various origin. The study was carried out in 75 women. Group I consisted of 32 women with prolactinoma, group II consisted of 43 women with functional hyperprolactinemia. Both groups were subdivided in patients with hypogonadism and normal gonadal function. The control group consisted of 29 healthy women. In all subjects PRL, PTH and its fractions (CAP, CIP), and bone turnover markers (BAP, ICTP) were studied. BMD measurement was carried out using DXA. In patients with functional hyperprolactinemia i-PTH and CAP levels were lower than in controls. CIP concentrations were lower in patients than in controls. CAP/CIP ratio was higher in patients with prolactinoma than in patients with functional hyperprolactinemia and controls. Higher values of bone turnover markers (BAP, ICTP) in patients groups and subgroups were shown as compared to controls. Some correlations between PTH and its fractions, and BMD and bone turnover were observed. There is no direct benefit from the assessment of parathormone fractions and CAP/CIP ratio in the prognosis of bone metabolism changes in hyperprolactinemia of various origin.

Although a growing body of research suggests that mind-body therapies may be appropriate to integrate into the treatment of depression, studies consistently lack methodological sophistication particularly in the area of control groups. In order to better understand the relationship between control group selection and methodological rigor, we provide a brief review of the literature on control group design in yoga and tai chi studies for depression, and we discuss challenges we have faced in the design of control groups for our recent clinical trials of these mind-body complementary therapies for women with depression. To address the multiple challenges of research about mind-body therapies, we suggest that researchers should consider 4 key questions: whether the study design matches the research question; whether the control group addresses performance, expectation, and detection bias; whether the control group is ethical, feasible, and attractive; and whether the control group is designed to adequately control for nonspecific intervention effects. Based on these questions, we provide specific recommendations about control group design with the goal of minimizing bias and maximizing validity in future research.

To determine whether fenbendazole effectively eliminates Giardia organisms from chronically infected cats that have a concurrent Cryptosporidium parvum infection. 16 clinically normal cats. Eight cats with chronic concurrent Giardia and C parvum infections received fenbendazole (50 mg/kg, PO, q 24 h) for 5 days (treatment-group cats). Feces from each cat were collected and processed 3 days weekly for 23 days after treatment. By use of an immunofluorescent assay for detection of Giardia lamblia cysts and C parvum oocysts, organism numbers were counted and scored. Fecal results from treatment-group cats were compared with those of 8 untreated cats with Giardia infection but no C parvum infection (control-group cats). Four of 8 treatment-group cats had consistently negative results for Giardia infection after treatment. These 4 cats had consistently positive results for C parvum oocysts prior to treatment and consistently negative results after treatment. One treatment-group cat had positive results for cysts on all fecal samples, and 3 treatment-group cats had 1 to 3 negative results and then resumed shedding large numbers of cysts; each of these cats had consistently positive results for C parvum oocysts. When compared with control-group cats, treatment-group cats shed less Giardia cysts during week 1 after treatment but not during week 2. Administration of fenbendazole decreases Giardia cyst shedding to less than detectable numbers in some cats. In our study, persistent C parvum infection may have been associated with failure of fenbendazole to eliminate Giardia infection.

[Purpose] The aim of this study was to investigate the changes of baseball pitching velocity and electromechanical reaction times (EMG-RT) of the teres major of young amateur baseball players after neuromuscular joint facilitation (NJF) treatment. [Subjects] The subjects were 18 healthy males who were divided into two groups: a NJF group and a control group. The NJF group consisted of 10 subjects, and the control group consisted of 8 subjects. [Methods] Participants in the NJF group received NJF treatment. The baseball pitching velocity, the EMG-RT, the premotor time (PMT), and the motor time (MT) during shoulder internal rotation movement were measured before and after 8 weeks of exercise. [Results] There were no significant differences among the results of the control group. In the NJF group, there were significant differences in baseball pitching velocity, EMG-RT and MT after NJF treatment. [Conclusion] NJF intervention shortens not only EMG-RT but also MT, which implies that NJF is effective for motor processes. Since the baseball pitching velocity increased, NJF may be recommended for the improvement of the performance of baseball players.

[Purpose] This study examined the effects of deep flexor muscle-strengthening exercise on the neck-shoulder posture, and the strength and endurance of the deep flexor muscles of high-school students. [Subjects] The subjects were 30 seventeen-year-old female high-school students who complained about bad posture and chronic neck-shoulder pain. They were randomly divided into an experimental group of 15 subjects, who performed a deep flexor muscle-strengthening exercise and a control group of 15 subjects, who performed a basic stretching exercise. [Methods] The experimental group of 15 subjects performed a deep flexor muscle-strengthening exercise consisting of low-load training of the cranio-cervical flexor muscle, and the control group of 15 subjects performed a basic stretching exercise consisting of seven motions. [Results] The experimental group showed statistically significant changes in head tilt angle, neck flexion angle, forward shoulder angle, and the result of the cranio-cervical flexion test after the training. In contrast, the control group showed no statistically significant changes in these measures following the training. When the results of the groups were compared, statistically significant differences were found for all items between the experimental group and the control group. [Conclusion] Strengthening cranio-cervical flexor muscles is important for the adjustment of neck posture, and maintaining their stability is required to improve neck-shoulder posture.

To study the surface, coloring, consistency, continuity and healing of osteochondral defects produced in the femoral condyles of rabbits and filled with sugar cane biopolymer gel (SCBG), after 90, 120 and 180 days, and in comparison with a control group. Sixteen adult New Zealand white rabbits aged 6 to 7 months, weighing between 2 and 2.5 kg and without locomotor system abnormalities were studied. In all the animals, a defect was made in the femoral condyles of the right and left knees, measuring 3.2 mm in diameter and 4 mm in depth, using a trephine. The animals were divided into two groups: study group formed by the right knees, in which the medial and lateral condyles received implants of SCBG; and control group formed by the left knees, in which the medial and lateral condyles were allowed to heal naturally. The knees were assessed 90, 120 and 180 days after the operation. After the animals had been sacrificed, the anatomical specimens were resected and placed in Bouin's solution. They were then photographed with a Nikon Coolpix 5400(®) coupled to a Nikon SM2800(®) stereoscopic loupe, to analyze the surface, coloring, consistency, continuity and healing. The results were evaluated using the chi-square test. There were no significant differences in the macroscopic assessments of healing between the study and control groups. With regard to the surface, coloring, consistency, continuity and healing of the defects, the macroscopic appearance of the tissue repaired with SCBG was similar to that of the control group.

Vaccination of Chinese bovines (cattle and buffaloes) against Schistosomiasis japonica with 36 kR gamma-irradiated schistosomula was done for laboratory challenge and for field trials in China. Altogether, 61 bovines were used. All experimental animals were vaccinated 2-3 times with 10,000 irradiated schistosomula per time. For the laboratory challenge, all experimental and control cattle were challenged with 500 normal cercariae and each buffalo, with 2,000 cercariae. The laboratory-challenged bovines were killed after 54-57 days of challenge; the bovines for the field trial in the lightly endemic area, after 5 months in the field; and the bovines for the field trial inmore » the heavily endemic area, after 58-63 days. When the animals were killed, the number of mature worms in the vaccinated (experimental) and non-vaccinated (control) animals was recorded and the percentage of worm reduction in each group was calculated. The first group, consisting of three vaccinated and three non-vaccinated cattle, was given a laboratory challenge; the worm reduction was 71.6%. The second group, consisting of two vaccinated and three non-vaccinated buffaloes, was also given a laboratory challenge; the worm reduction was 74.4%. The third group, consisting of seven vaccinated and eight non-vaccinated buffaloes, was utilized in a field trial in a lightly endemic area; the worm reduction was 75.6%. The fourth group, consisting of eight vaccinated and nine non-vaccinated cattle, and the fifth group, consisting of nine vaccinated and nine non-vaccinated buffaloes, were pastured in a heavily endemic area.

2018-01-01

Background Attention-deficit/hyperactivity disorder (ADHD)-like symptoms are common in fetal alcohol spectrum disorders (FASD). FASD and ADHD groups both display executive function impairments; however, there is ongoing debate whether the pattern and magnitude of executive function deficits differs between these two types of disorders. Methods An electronic literature search was conducted (PubMed, PsychInfo; 1972–2013) to identify studies comparing the executive functioning of children with FASD with ADHD or control groups. FASD groups included those with and without dysmorphy (i.e., FAS, pFAS, ARND, and other FASD diagnoses). Effect sizes (Hedges’ g, standardized mean difference) were calculated. Random effects meta-analytic models were performed using the metafor package for R. Results Fifty-one studies met inclusion criteria (FASD N = 2,115; ADHD N = 453; controls N = 1,990). Children with FASD showed the strongest and most consistent deficits in planning, fluency, and set-shifting compared to controls (Hedges’ g = −0.94, −0.78) and children with ADHD (Hedges’ g = −0.72, −0.32). FASD was associated with moderate to large impairments in working memory, compared to controls (Hedges’ g = −.84, −.58) and small impairments relative to groups with ADHD (Hedges’ g = −.26). Smaller and less consistent deficits were found on measures of inhibition and vigilance relative to controls (Hedges’ g = −0.52, −0.31); FASD and ADHD were not differentiated on these measures. Moderator analyses indicated executive dysfunction was associated with older age, dysmorphy, and larger group differences in IQ. Sex and diagnostic system were not consistently related to effect size. Conclusions While FASD is associated with global executive impairments, executive function weaknesses are most consistent for measures of planning, fluency, and set-shifting. Neuropsychological measures assessing these executive function domains may improve differential diagnosis and treatment of FASD. PMID:26251262

First-line treatment for advanced ovarian cancer: paclitaxel, platinum and the evidence

2002-01-01

Four large randomised trials of paclitaxel in combination with platinum against a platinum-based control treatment have now been published in full, representing around 88% (3588 out of 4057) of patients randomised into the eight known trials of this question. There is substantial heterogeneity in the results of these four trials. Four main explanations for this heterogeneity have been proposed: differences in the extent and timing of ‘crossover’ to taxanes in the control groups; differences in the types of patient included; differences in the effectiveness of the research regimens used; differences in the effectiveness of the control regimens used. In this study we examine whether any of these explanations is consistent with the pattern of results seen in these trials. Each explanation suggests that a particular characteristic of each trial was responsible for the results observed. For each explanation the trials were split into groups according to that characteristic, in order to partition the total heterogeneity into that seen ‘within’ and ‘between’ groups of trials. If a particular explanation was consistent with the pattern of results, we would expect to see relatively little heterogeneity within each group of trial results viewed in this way, with most of the heterogeneity being between groups which are dissimilar with respect to the key characteristic. Heterogeneity ‘within’ and ‘between’ groups was formally compared using the F-ratio. If any explanation appeared to be consistent with the results of the trials, it was considered whether the explanation was also consistent with other evidence available about these regimens. Only one explanation appeared to be consistent with the pattern of results seen in these trials, and that was differences in effectiveness of the control arms used in these trials. This suggests that the very positive results in favour of paclitaxel/cisplatin seen in two of the trials may have been due to the use of a suboptimal control arm. There is no direct evidence about the relative effectiveness of the control arms used in these trials, but indirect evidence is consistent with the conclusion that the cyclophosphamide/cisplatin regimen used in two of the trials may be less effective than the control regimens used in the other trials. Specific concerns about the choice of a cyclophosphamide/cisplatin control arm in the first of these trials to report were raised before the results of the other trials were known, i.e. before any heterogeneity had been observed. Further investigation of this question would be useful. In the meantime, given all of the randomised evidence on the efficacy and toxicity associated with the regimens used in these trials, we conclude that single agent carboplatin is a safe and effective first-line treatment for women with advanced ovarian cancer.

To evaluate the effect of nephrostomy tubing with balloon on postoperative hemorrhage after percutaneous nephrolithotomy. A total of 284 patients with upper urinary calculi were enrolled for blocked randomization with 71 blocks and block length of 4. The experimental group consisted of 143 patients receiving 14-Fr silicone tubing with balloon, and the control group consisted of 141 patients receiving 14-Fr silicone tubing without balloon. One patient in the control group developed intraoperative bleeding as a result of calyceal laceration, and was reassigned to the experimental group receiving nephrostomy tubing with balloon. Postoperative drop in hemoglobin level at 3 days was significantly less in the experimental group (3.31 ± 2.85 g/L) compared with the control group (5.14 ± 3.43 g/L) (P < 0.001). The duration of gross hematuria, defined by urine with visible light or bright red color (2.73 ± 1.59 days vs. 3.55 ± 2.09 days, P < 0.001), and the incidence of postoperative extravasation (22/143 vs. 38/141, P < 0.05) for patients in the experimental group (implanted with 14-Fr silicone tubing with balloon) were significantly lower compared with the control group. Use of indwelling nephrostomy tubes with balloon after percutaneous nephrolithotomy can reduce blood loss. Further consideration for more widespread adoption of this type of tubing to limit perioperative bleeding complications is warranted. © 2015 The Japanese Urological Association.

To determine the normal serum levels of LDL-cholesterol, apolipoprotein-B, ferritin, uric acid, and the extent of erythrocytes lipid peroxidation in healthy control group subjects and to compare them with coronary heart disease patients. Secondly, to study the effects of age and sex on these parameters. The blood samples from 150 healthy Libyan control group subjects (110 men and 40 women) were classified into 3 groups according to their age. Group I consisted of 76 subjects with an age range from 20 to 35 years. Group II consisted of 45 subjects with an age range from 36 to 50 years. Group III consisted of 29 subjects with an age range from 51 to 74 years. The blood samples from these groups were analyzed for LDL-cholesterol, apolipoprotein-B, ferritin and uric acid levels. Lipid peroxidation was compared in the erythrocytes of 56 selected healthy control group subjects (31 men and 11 women) of the aforementioned age groups. These parameters have shown age-dependent elevation in their levels. Meanwhile, LDL-cholesterol and Apolipoprotein-B levels in female subjects were higher than those of males. However, lipid peroxidation in the erythrocytes has revealed a statistically significant increase with increasing age. The comparison between 93 selected, sex and age matched, healthy control group subjects with 87 selected coronary heart disease patients (55 men and 45 women) with an age range from 30 to 74 years (49.6+13.25) has demonstrated significantly higher concentration of LDL-cholesterol, Apolipoprotein-B, ferritin and uric acid in coronary heart disease patients than those of healthy control group subjects. Meanwhile, lipid peroxidation was also significantly enhanced in coronary heart disease patients compared with healthy control group subjects. Our study has revealed that an increase in the lipid peroxidation in erythrocytes with age and during coronary heart disease, makes red cell membranes more vulnerable to free radical damage via formation of reactive oxygen species. It is thus likely that peroxidative damage may be contributing to an increase in serum LDL-cholesterol, Apolipoprotein-B, probably after its oxidative modification, increase in ferritin and hyperuricemia in coronary heart disease patients.

Multiplayer virtual world (MVW) technology creates opportunities to practice medical procedures and team interactions using serious game software. This study aims to explore medical students' retention of knowledge and skills as well as their proficiency gain after pre-training using a MVW with avatars for cardio-pulmonary resuscitation (CPR) team training. Three groups of pre-clinical medical students, n = 30, were assessed and further trained using a high fidelity full-scale medical simulator: Two groups were pre-trained 6 and 18 months before assessment. A reference control group consisting of matched peers had no MVW pre-training. The groups consisted of 8, 12 and 10 subjects, respectively. The session started and ended with assessment scenarios, with 3 training scenarios in between. All scenarios were video-recorded for analysis of CPR performance. The 6 months group displayed greater CPR-related knowledge than the control group, 93 (±11)% compared to 65 (±28)% (p < 0.05), the 18 months group scored in between (73 (±23)%).At start the pre-trained groups adhered better to guidelines than the control group; mean violations 0.2 (±0.5), 1.5 (±1.0) and 4.5 (±1.0) for the 6 months, 18 months and control group respectively. Likewise, in the 6 months group no chest compression cycles were delivered at incorrect frequencies whereas 54 (±44)% in the control group (p < 0.05) and 44 (±49)% in 18 months group where incorrectly paced; differences that disappeared during training. This study supports the beneficial effects of MVW-CPR team training with avatars as a method for pre-training, or repetitive training, on CPR-skills among medical students.

Systolic Blood Pressure Intervention Trial (SPRINT) and Target Systolic Blood Pressure in Future Hypertension Guidelines.

Egan, Brent M; Li, Jiexiang; Wagner, C Shaun

2016-08-01

The Systolic Blood Pressure (SBP, mm Hg) Intervention Trial (SPRINT) showed that targeting SBP <120 mm Hg (intensive treatment, mean SBP: 121.5 mm Hg) versus <140 (standard treatment, mean SBP: 134.6 mm Hg) reduced cardiovascular events 25%. SPRINT has 2 implicit assumptions that could impact future US hypertension guidelines: (1) standard therapy controlled SBP similarly to that in adults with treated hypertension and (2) intensive therapy produced a lower mean SBP than in adults with treated hypertension and SBP <140 mm Hg. To examine these assumptions, US National Health and Nutrition Examination Survey 2009 to 2012 data were analyzed on 3 groups of adults with treated hypertension: group 1 consisted of SPRINT-like participants aged ≥50 years; group 2 consisted of participants all aged ≥18 years; and group 3 consisted of participants aged ≥18 years excluding group 1 but otherwise similar to SPRINT-like participants except high cardiovascular risk. Mean SBPs in groups 1, 2, and 3 were 133.0, 130.1, and 124.6, with 66.2%, 72.2%, and 81.9%, respectively, controlled to SBP <140; 68.3%, 74.8%, and 83.4% of the controlled subset had SBP <130. Mean SBPs in those controlled to <140 were 123.3, 120.9, and 118.9, respectively. Among US adults with treated hypertension, (1) the SPRINT-like group had higher mean SBP than comparison groups, yet lower than SPRINT standard treatment group and (2) among groups 1 to 3 with SBP <140, SBP values were within <3 mm Hg of SPRINT intensive treatment. SPRINT results suggest that treatment should be continued and not reduced when treated SBP is <130, especially for the SPRINT-like subset. Furthermore, increasing the percentage of treated adults with SBP <140 could approximate SPRINT intensive treatment SBP without lowering treatment goals. © 2016 American Heart Association, Inc.

2011-02-01

This research used a matching-to-sample procedure and equivalence learning process with language and verbal tasks. In the study, an application of the equivalence relationship of money was used with several kinds of euro coins presented. The sample consisted of 16 children (8 in the experimental group and 8 in the control group) aged 5 years. The prerequisite behaviors, the identification of coins and the practical use of different euro coins, were assessed in the pre and post phases for both groups. The children in the experimental group performed an equivalence task using the matching-to-sample procedure. This consisted of a stimulus sample and four matching stimuli, using a series of euro coins with equivalent value in each set. The children in the control group did not undergo this training process. The results showed a large variability in the children's data of the equivalence tests. The experimental group showed the greatest pre and post changes in the statistically significant data. They also showed a greater generalization in the identification of money and in the use of euro coins than the control group. The implications for educational training and the characteristics of the procedure used here for coin equivalence are discussed.

Grouping of reactions around key metabolite branch points can facilitate the study of metabolic control of complex metabolic networks. This top-down Metabolic Control Analysis is exemplified through the introduction of group control coefficients whose magnitudes provide a measure of the relative impact of each reaction group on the overall network flux, as well as on the overall network stability, following enzymatic amplification. In this article, the authors demonstrate the application of previously developed theory to the determination of group flux control coefficients. Experimental data for the changes in metabolic fluxes obtained in response to the introduction of six different environmentalmore » perturbations are used to determine the group flux control coefficients for three reaction groups formed around the phosphoenolpyruvate/pyruvate branch point. The consistency of the obtained group flux control coefficient estimates is systematically analyzed to ensure that all necessary conditions are satisfied. The magnitudes of the determined control coefficients suggest that the control of lysine production flux in Corynebacterium glutamicum cells at a growth base state resides within the lysine biosynthetic pathway that begins with the PEP/PYR carboxylation anaplorotic pathway.« less

2015-01-01

This in vitro study is intended to compare the shear bond strength of recent self-etching primers to superficial, intermediate, and deep dentin levels. All teeth were sectioned at various levels and grouped randomly into two experimental groups and two control groups having three subgroups. The experimental groups consisted of two different dentin bonding system. The positive control group consisted of All Bond 2 and the negative control group was without the bonding agent. Finally, the specimens were subjected to shear bond strength study under Instron machine. The maximum shear bond strengths were noted at the time of fracture. The results were statistically analyzed. Comparing the shear bond strength values, All Bond 2 (Group III) demonstrated fairly higher bond strength values at different levels of dentin. Generally comparing All Bond 2 with the other two experimental groups revealed highly significant statistical results. In the present investigation with the fourth generation, higher mean shear bond strength values were recorded compared with the self-etching primers. When intermediate dentin shear bond strength was compared with deep dentin shear bond strength statistically significant results were found with Clearfil Liner Bond 2V, All Bond 2 and the negative control. There was a statistically significant difference in shear bond strength values both with self-etching primers and control groups (fourth generation bonding system and without bonding system) at superficial, intermediate, and deep dentin. There was a significant fall in bond strength values as one reaches deeper levels of dentin from superficial to intermediate to deep.

Westin, S; Norum, D; Schlesselman, J J

1988-03-01

The effect of a factory shut-down on sick leave and disability pensions was investigated in a four-year controlled follow-up study in a general practice setting. The study population consisted of 85 people, 72 women and 13 men, who lost their jobs when a sardine factory near Bergen in Norway was shut down in 1975. The employees of a nearby sister factory' within the same company were chosen as a control population, consisting of 87 people, 66 women and 21 men. The average amount of sick leave for the study group within the first year of follow-up showed a twofold increase compared to the controls. The rate of disability pensions, estimated by the life table method with appropriate adjustments, was more than three times higher in the study group than in the control group from the second through the fourth year of follow-up. The results of this investigation provide further evidence in support of a causal relationship between job loss and illness.

2010-05-01

The present study examines the psychometric properties of the German version of the Eating Disorder Inventory EDI-2 (1997) in 371 adolescents aged 13 to 18 years. Internal consistency, convergent and divergent validity were examined and a confirmatory factor analysis was conducted. Internal consistency was high for the group of patients and satisfactory for both control groups. Associations with other clinical instruments point in the expected direction and support the external validity of the EDI-2. The EDI-2 differentiated very well between the group of eating disorder patients (n=71) and the female (n=150) and male control groups (n=150). A discriminant analysis demonstrated that 86.0% of the cases were correctly classified, and a confirmatory factor analysis largely supported the six-factor structure generated by the German version of the EDI-2 (Thiel et al., 1997).

To evaluate the survival rate of dental implants replacing failed implants in grafted maxillary sinuses using the lateral approach vs nongrafted posterior maxillae. A retrospective analysis was conducted to study the survival of secondary dental implants inserted in the posterior maxilla in previously failed implant sites between the years 2000 and 2010. The study group consisted of patients who had also undergone maxillary sinus augmentation, and the control group consisted of patients in whom implants in the posterior maxilla had failed. Clinical and demographic data were analyzed using a structured form. Seventy-five patients with a total of 75 replaced implants were included in the study. The study group comprised 40 patients and the control group, 35 patients. None of the replaced implants in the study group failed, resulting in an overall survival of 100%; three replaced implants in the control group failed (92% survival). The main reason for the primary implant removal was lack of osseointegration (35 [87.5%] of 40 study group implants and 23 [65.7%] of 35 control group implants [P = .027]). The difference between the groups with regard to the timing of primary implant failure was statistically significant. The study group had more early failures of the primary implant than did the control group (77% vs 62%; P = .038). Dental implants replaced in the posterior maxilla had a high survival rate. A higher rate of survival was found in augmented maxillary sinus sites. Within the limits of the present study, it can be concluded that previous implant failures in the grafted maxillary sinus should not discourage practitioners from a second attempt.

AIM: To assess the efficacy and safety of Saccharomyces boulardii (S. boulardii) in acute watery diarrhoea and its role in reducing the frequency of episodes of diarrhoea in subsequent two months. METHODS: Children from 2 mo to 12 years of age, with acute diarrhoea were selected according to inclusion criteria and randomised in S. boulardii group (treated with ORS, nutritional support and S. boulardii, 250 mg bid) and in control group (treated with ORS and nutritional support only). Active treatment phase was 5 d and each child was followed for two months afterwards. Frequency and consistency of stools as well as safety of drug was assessed on every visit. A comparison of two groups was done in terms of number of diarrhoeal episode in subsequent two months. RESULTS: There were fifty patients in each group. Baseline characteristics such as mean age and the average frequency of stools were comparable in S. boulardii and control group at the time of inclusion in the trial. By d 3 it reduced to 2.7 and 4.2 stools per d respectively and by d 6 it reduced to 1.6 (S. boulardii Group) and 3.3 (control group). The duration of diarrhoea was 3.6 d in S. boulardii group whereas it was 4.8 d in control group (P = 0.001). In the following two months, S. boulardii group had a significantly lower frequency of 0.54 episodes as compared to 1.08 episodes in control group. The drug was well accepted and tolerated. There were no reports of the side effects during treatment period. CONCLUSION: S. boulardii significantly reduces the frequency and duration of acute diarrhoea. The consistency of stool also improves. The drug is well-tolerated. PMID:16874872

Because of the specific structure of forensic medicine in Turkey, reexamination of histopathologic specimens is a frequent practice. The aim of the present study is the assessment of microscopic diagnostic consistency in forensic pathology between different laboratories. Reports of the Council of Forensic Medicine between 2001 and 2004 were examined, and 150 cases with second pathologic examination were found. Results of histopathologic reports from peripheral laboratories were compared with those made by the Council pathologists with regard to diagnostic consistency. Consistency was assessed in 3 groups and 1 subgroup. Group 1, consistent and minor inconsistency; includes a major consistency subgroup. Group 2, major inconsistency, is the second diagnosis which is lethal; group 3, major inconsistency, is the first diagnosis which is lethal. The lung was found to be the organ with the highest frequency of diagnostic major inconsistency (group 2 and 3) and major consistency. Bronchopneumonia was the most common diagnosis. The brain had the highest frequency of intercenter diagnostic overall consistency (90.2%, group 1). Myocardial infarction was the diagnosis most frequently rejected on reevaluation (group 3). In conclusion, forensic pathology requires different experience than surgical ones. In cases of discrepancy between the anamnesis of the lethal event and pathologic findings, reevaluation of specimen is mandatory to avoid any diagnostic errors. Quality assurance systems with all include internal and external control mechanisms will improve the diagnostic reliability.

It has been known that mind-body training (MBT) can affect personality and behavior system as well as emotional well-being, but different effects of MBT on them has not been reported according to BDNF genetic polymorphism. Healthy subjects consisted of 64 subjects and the MBT group who practiced meditation regularly consisted of 72 practitioners. Participants completed neuroticism-extraversion-openness (NEO) Five-Factor Inventory and Behavioral Activation System/Behavioral Inhibition System (BAS/BIS) scales. All subjects were genotyped for the BDNF Val66Met polymorphism. In the same genotypes of the BDNF Val/Val+Val/Met group, MBT group showed the increased Extraversion (p=0.033) and the increased Openness to Experience (p=0.004) compared to the control group. Also, in the same Met/Met carriers, MBT group exhibited the increase of Extraversion (p=0.008), the reduction of Neuroticism (p=0.002), and the increase of Openness to Experience (p=0.008) compared to the control group. In the same genotypes of the BDNF Val/Val+Val/Met group, MBT group showed the decreased BAS-Reward Responsiveness (p=0.016) and the decrease of BIS (p=0.004) compared to the control group. In the BDNF Met/Met group, MBT group increased BAS-Fun Seeking (p=0.045) and decreased BIS (p=0.013) compared to the control group. MBT would differently contribute to NEO personality and BAS/BIS according to BDNF genetic polymorphism, compensating for different vulnerable traits based on each genotype.

2017-02-01

To study the effects of person-centred care provided to patients with acute coronary syndrome, using four different health-related outcome measures. Also, to examine the performance of these outcomes when measuring person-centred care. The data used in this study consists of primary data from a multicentre randomized parallel group, controlled intervention study for patients with acute coronary syndrome at Sahlgrenska University Hospital in Gothenburg, Sweden. The intervention and control group consisted of 94 and 105 patients, respectively. The effect of the intervention on health-related outcomes was estimated, controlling for socio-economic and disease-related variables. Patients in the intervention group reported significantly higher general self-efficacy than those in the control group six months after intervention start-up. Moreover, the intervention group returned to work in a greater extent than controls; their physical activity level had increased more and they had a higher EQ-5D score, meaning higher health-related quality of life. These latter effects are not significant but are all pointing towards the beneficial effects of person-centred care. All the effects were estimated while controlling for important socio-economic and disease-related variables. The effectiveness of person-centred care varies between different outcomes considered. A statistically significant beneficial effect was found for one of the four outcome measures (self-efficacy). The other measures all captured beneficial, but not significant, effects.

Abstract The impact of the posterior callosal anomalies associated with spina bifida on interhemispheric cortical connectivity is studied using a method for estimating cortical multivariable autoregressive models from scalp magnetoencephalography data. Interhemispheric effective and functional connectivity, measured using conditional Granger causality and coherence, respectively, is determined for the anterior and posterior cortical regions in a population of five spina bifida and five control subjects during a resting eyes-closed state. The estimated connectivity is shown to be consistent over the randomly selected subsets of the data for each subject. The posterior interhemispheric effective and functional connectivity and cortical power are significantly lower in the spina bifida group, a result that is consistent with posterior callosal anomalies. The anterior interhemispheric effective and functional connectivity are elevated in the spina bifida group, a result that may reflect compensatory mechanisms. In contrast, the intrahemispheric effective connectivity is comparable in the two groups. The differences between the spina bifida and control groups are most significant in the θ and α bands.

Children with Specific Language Impairment (SLI) have demonstrated general spelling and writing difficulties. We investigated the sensitivity of children with SLI to the consistent spelling of root morphemes, a feature to which young typically developing children demonstrate sensitivity. We asked children with SLI and two groups of typically developing children (n = 17 in each group) to spell the same letter-sound sequence (e.g., win) as a root, and as a component of inflected, derived, and control words (e.g., win, wins, winner, wink). Children with SLI and spelling-age-matched children (mean age of 9 and 7 years, respectively) were more accurate and more consistent in spelling the initial sections of the inflected and derived words than of the control words, a pattern that suggests sensitivity to the representation of roots in spelling. The absence of a group-level interaction suggests comparable sensitivity in the two groups. Our results suggest that elementary-school-aged children with SLI are sensitive to the consistent spelling of roots, at least to the extent predicted by their general spelling abilities.

To evaluate whether a consultation skills training (CST) program with oncologists and trainees would improve skills in detecting and responding to patient distress, thereby improving their patients' emotional functioning and reducing psychological distress. Randomized-controlled trial with 29 medical and radiation oncologists from Australia randomized to CST group (n=15) or usual-care group (n=14). The CST consisted of a 1.5-day face-to-face workshop incorporating presentation of principles, a DVD modelling ideal behaviour and role-play practice, and four 1.5h monthly video-conferences. At the CST conclusion, patients of participating doctors were recruited (n=192 in CST group, n=183 in usual-care group), completing telephone surveys at baseline, 1 week and 3 months to assess quality of life, anxiety, depression and unmet psychosocial needs. Despite high patient functioning at baseline, anxiety significantly improved at 1-week follow-up in the CST group, compared to the control group. There were no statistically significant differences in emotional functioning, depression or unmet supportive care need between the groups. Consistent trends for greater improvements were observed in intervention compared to control group patients, suggesting the CST program deserves wider evaluation. Video-conferencing after a short training course may be an effective strategy for delivering CST.

The best surgical strategy for the management of perforated diverticulitis with generalized peritonitis of the sigmoid colon is not clearly defined. The aim of this retrospective cohort study was to evaluate the value of a damage control strategy. All patients who underwent emergency laparotomy for perforated diverticular disease of the sigmoid colon with generalized peritonitis between 2010 and 2015 were included. The damage control strategy (study group), included a two- stage procedure: limited resection of the diseased colonic segment, closure of proximal colon and distal stump, and application of an abdominal vacuum at the initial surgery followed by second-look laparotomy 24-48 h later At this point a choice was made between anastomosis and Hartmann's procedure. The control group consisted of patients receiving definitive reconstruction (anastomosis or Hartmann's procedure) at the initial operation. Thirty-seven patients were included in the study. Damage control strategy was applied in 19 patients and the control group consisted of 18 patients. Both groups were comparable in terms of demographics, severity of peritonitis, and comorbidities. The overall postoperative mortality was 11 % (n = 4). There were no statistically significant differences between both groups regarding postoperative morbidity and mortality; however, a significantly higher proportion of patients in the control group had a stoma after the initial hospital stay (83 vs. 47 %, p = 0.038). This difference was still significant after adjustment for sex, age, Mannheim Peritonitis Index, American Society of Anesthesiologists class and presence of septic shock at presentation. At the end of the follow-up period, 15 of 17 survivors in the study group and 13 of 16 survivors in the control group had their intestinal continuity restored (p = 0.66). Damage control strategy in patients with generalized peritonitis due to perforated diverticulitis leads to a significantly reduced stoma rate after the initial hospital stay without an increased risk of postoperative morbidity.

Physiologic responses of 30 enterally-fed long-term care residents with type 2 diabetes receiving total nutrition support via either a disease-specific (reduced-carbohydrate, modified-fat) formula or a standard high-carbohydrate formula for 3 mo were compared. Objectives of the study included evaluating metabolic response (glycemic control and lipids) and clinical outcomes. Thirty-four subjects requiring total enteral nutrition support by tube were enrolled in this prospectively randomized, double-blind, controlled, parallel group 3-mo pilot trial. Thirty were evaluable in that they completed 4 wk. Twenty-seven completed all 12 wk. The groups were well-matched for physiologic and demographic parameters at baseline. Fasting serum glucose and capillary (fingerstick) glucose values demonstrated better control in the disease-specific formula-fed group. Serum lipid profiles of this group were similar to or better than those of the standard formula-fed group. The amount of insulin administered to insulin-using subjects in the disease-specific formula-fed group was consistently less than before initiation of the formula, whereas the amount administered was consistently higher in the group fed the standard formula. Overall, subjects randomized to the disease-specific formula experienced better numerical biochemical control and better clinical outcomes when expressed on a numerical and percentage basis. These included surrogate markers of diabetes control such as serum glucose and glycohemoglobin, as well as clinical outcomes such as incidence of infections and pressure ulcers. These findings confirm that the disease-specific formula provides better glycemic control, poses no risk to lipoprotein metabolism, and provides for better clinical outcomes.

The objective of this pilot 6-month randomized controlled trial was to determine the effectiveness of an intensive, community-based, group intervention that focused on diet, physical activity, and peer support for reducing weight among urban-dwelling African Americans with comorbid type 2 diabetes and hypertension. Sixty-one participants were randomized into an intervention or control group. The 6-month intervention consisted of 18 group sessions led by a dietitian in a community setting and weekly telephone calls from a peer supporter. The intervention featured culturally tailored nutrition education, behavioral skills training, and social support focused on changes to diet and physical activity. The control group consisted of two 3-hour group sessions of diabetes self-management education taught by a community health worker. Outcome measures were assessed at baseline and 6 months. The primary outcome was achievement of a 5% weight reduction at 6 months. A secondary outcome was achievement of a 0.5 percentage-point reduction in hemoglobin A1c (HbA1c). Groups did not differ in achievement of the weight-loss goal. Intervention participants lost a mean of 2.8 kg (P = .01); control participants did not lose a significant amount of weight. A greater proportion of intervention (50.0%) than control (21.4%) participants reduced HbA1c by 0.5 percentage points or more at 6 months (P = .03). The intervention was more effective than usual care (short-term diabetes education) at improving glycemic control, but not weight, in low-income African Americans with comorbid diabetes and hypertension. A community-based 6-month group class with culturally tailored education, behavioral skills training, and peer support can lead to a clinically significant reduction in HbA1c.

This study was done to develop a children's sex education program for the parents of lower elementary grade students and to evaluate its effects on sexual knowledge, gender role attitude, parent efficacy for child's sex education, and marital consistency. A quasi-experimental with a non-equivalent control group pretest-posttest design was used. The participants were 29 couples (58 parents, experimental group=28, control group=30) from G city. The 5-week (5-session) program was developed based on 'A theory of protection: parents as sex educators' and used the case-based small group learning method. Data were collected during July and August 2015. The characteristics of the program developed in the present study were a theoretical-based, client-centered, multi-method. After the intervention, the experimental group showed a significant improvement in sexual knowledge, gender role attitudes, parent efficacy for child's sex education, and marital consistency, compared to the control group. The effect sizes of the program were .64 (knowledge), .65 (gender role attitudes), and .68 (parent efficacy). The results of this study provided implications for the parents as effective sex educator and the role expansion of school health nurses. © 2017 Korean Society of Nursing Science

The objective of this study is to determine the effect of yoga on functional recovery level in schizophrenic patients. The study was conducted in quasi-experimental design with pretest-posttest control group. The population of the study consisted of schizophrenic patients with registered in Malatya and Elazığ Community Mental Health Centers and regularly going to these centers. The sample group of the study consisted of totally 100 patients including 50 patients in the experimental group and 50 patients in the control group who were specified through power analysis and chosen by using random sampling method from this population. The data were collected between April 2015 and August 2015. 'Patient Description Form' and 'FROGS' were used to collect the data. Yoga was applied to patients in the experimental group. Any intervention was not made to patients in the control group. Percentage distribution, arithmetic mean, standard deviation, chi-square, independent samples t test, and paired t test were used to assess the data. Patients in the control and experimental group pretest subscale and the total means scores of FROGS was found to be low. In the posttest subscale and total means scores of FROGS in the experimental group were higher than in the control group and the differences between them were found to be statistically significant (p<0.05). In the experimental group pretest and posttest subscale and total means scores of FR0GS was determined to be statistically significant (p<0.05). Yoga that applied to schizophrenic patients it was determined to increased the level of functional recovery. It can be suggested that yoga should be used as an complementary method in nursing practise in order to increase the effectiveness of the treatment. Copyright © 2016 Elsevier Inc.

Folic acid deficiency is a risk factor for schizophrenia through epidemiology, biochemistry and gene-related studies. Compared with healthy people, schizophrenic patients may have high homocysteine plasma values and homocysteine or low levels of folic acid, which seems to correlate with extrapyramidal motor symptoms caused by neuroleptic therapy and with symptoms of schizophrenia. In this present study, we focus on the difference of folic acid level between schizophrenic patient and control group. The study sample consisted of schizophrenic patients and 14 people in the control group and performed blood sampling to obtain the results of folic acid levels. The folic acid level in both groups was within normal range, but the schizophrenic patient group had lower mean folic acid values of 5.00 ng/ml (sb 1.66), compared with the control group with mean folic acid values of 10.75 ng/ml (sb 4.33). there was the group of the control group had a higher value of folic acid than the schizophrenic group.

Striving for group agency: threat to personal control increases the attractiveness of agentic groups.

PubMed

Stollberg, Janine; Fritsche, Immo; Bäcker, Anna

2015-01-01

When their sense of personal control is threatened people try to restore perceived control through the social self. We propose that it is the perceived agency of ingroups that provides the self with a sense of control. In three experiments, we for the first time tested the hypothesis that threat to personal control increases the attractiveness of being part or joining those groups that are perceived as coherent entities engaging in coordinated group goal pursuit (agentic groups) but not of those groups whose agency is perceived to be low. Consistent with this hypothesis we found in Study 1 (N = 93) that threat to personal control increased ingroup identification only with task groups, but not with less agentic types of ingroups that were made salient simultaneously. Furthermore, personal control threat increased a sense of collective control and support within the task group, mediated through task-group identification (indirect effects). Turning to groups people are not (yet) part of, Study 2 (N = 47) showed that personal control threat increased relative attractiveness ratings of small groups as possible future ingroups only when the relative agency of small groups was perceived to be high. Perceived group homogeneity or social power did not moderate the effect. Study 3 (N = 78) replicated the moderating role of perceived group agency for attractiveness ratings of entitative groups, whereas perceived group status did not moderate the effect. These findings extend previous research on group-based control, showing that perceived agency accounts for group-based responses to threatened control.

Formula-fed (FF) infants often have harder stools and higher stool concentrations of fatty acid soaps compared to breastfed infants. Feeding high sn-2 palmitate or the prebiotic oligofructose (OF) may soften stools, reduce stool soaps, and decrease fecal calcium loss. We investigated the effect of high sn-2 palmitate alone and in combination with OF on stool palmitate soap, total soap and calcium concentrations, stool consistency, gastrointestinal (GI) tolerance, anthropometrics, and hydration in FF infants. This double-blind trial randomized 165 healthy term infants 25-45 days old to receive Control formula (n = 54), formula containing high sn-2 palmitate (sn-2; n = 56), or formula containing high sn-2 palmitate plus 3 g/L OF (sn-2+OF; n = 55). A non-randomized human milk (HM)-fed group was also included (n = 55). The primary endpoint, stool composition, was determined after 28 days of feeding, and was assessed using ANOVA accompanied by pairwise comparisons. Stool consistency, GI tolerance and hydration were assessed at baseline, day 14 (GI tolerance only) and day 28. Infants fed sn-2 had lower stool palmitate soaps compared to Control (P = 0.0028); while those fed sn-2+OF had reduced stool palmitate soaps compared to both Control and sn-2 (both P < 0.0001). Stool total soaps and calcium were lower in the sn-2+OF group than either Control (P < 0.0001) or sn-2 (P < 0.0001). The HM-fed group had lower stool palmitate soaps, total soaps and calcium (P < 0.0001 for each comparison) than all FF groups. The stool consistency score of the sn-2+OF group was lower than Control and sn-2 (P < 0.0001), but higher than the HM-fed group (P < 0.0001). GI tolerance was similar and anthropometric z-scores were <0.2 SD from the WHO growth standards in all groups, while urinary hydration markers were within normal range for all FF infants. Increasing sn-2 palmitate in infant formula reduces stool palmitate soaps. A combination of high sn-2 palmitate and OF reduces stool palmitate soaps, total soaps and calcium, while promoting softer stools. This study was registered on http://www.clinicaltrials.gov: number NCT02031003.

The aim of this study was to investigate the effect of an educational programme for patients with polyarthritis compared to usual care. Patients with rheumatoid arthritis, psoriatic arthritis and unspecified polyarthritis were randomised to the intervention (n=71) or usual care (n=70). The intervention consisted of three group educational sessions followed by one individual educational session. The primary outcomes were a patient's global well-being and arthritis self-efficacy. Secondary outcomes were patient activation, physical and psychological health status, educational needs and disease activity. After four months the intervention group had significantly better global well-being, 95% CI (2.3-14.1), p=0.01, and self-efficacy, 95% CI (0.2-8.1), p=0.04, than the control group. There were also trends for improved disease activity, and a statistically significant improvement in patient activation and pain in the intervention group. This patient educational programme consisting of group sessions and nurse-delivered individual education has statistically significant benefits for global well-being and maintaining a level of self-efficacy in managing other symptoms in patients with polyarthritis. This educational programme allows patients to learn from each other in addition to addressing individual educational needs. Copyright © 2011 Elsevier Ireland Ltd. All rights reserved.

Reducing bias and analyzing variability in the time-left procedure.

PubMed

Trujano, R Emmanuel; Orduña, Vladimir

2015-04-01

The time-left procedure was designed to evaluate the psychophysical function for time. Although previous results indicated a linear relationship, it is not clear what role the observed bias toward the time-left option plays in this procedure and there are no reports of how variability changes with predicted indifference. The purposes of this experiment were to reduce bias experimentally, and to contrast the difference limen (a measure of variability around indifference) with predictions from scalar expectancy theory (linear timing) and behavioral economic model (logarithmic timing). A control group of 6 rats performed the original time-left procedure with C=60 s and S=5, 10,…, 50, 55 s, whereas a no-bias group of 6 rats performed the same conditions in a modified time-left procedure in which only a single response per choice trial was allowed. Results showed that bias was reduced for the no-bias group, observed indifference grew linearly with predicted indifference for both groups, and difference limen and Weber ratios decreased as expected indifference increased for the control group, which is consistent with linear timing, whereas for the no-bias group they remained constant, consistent with logarithmic timing. Therefore, the time-left procedure generates results consistent with logarithmic perceived time once bias is experimentally reduced. Copyright © 2015 Elsevier B.V. All rights reserved.

Cariogenic Potential of Inhaled Antiasthmatic Drugs.

The organism of children with asthma is exposed to the effects of the disease but also the drugs for its treatment. Antiasthmatic drugs have different modes that promote the caries formation which varies according to their basic pharmacological composition. Namely, these drugs have a relatively low pH (5.5), can contain sweeteners such as lactose monohydrate in order to improve the drug taste or both. Frequent consumption of these inhalers in combination with reduced secretion of saliva increases the risk of caries. The study sample consisted of 200 patients, age from 7-14 years, divided into two groups: control group (n1 = 100) consisted of healthy children and the experimental group consisted of children suffering from asthma (n2 = 100). In both groups of respondents are determined the DMFT index, plaque index value and hygienic-dietary habits using the questionnaire. The subjects in the control group had significantly higher DMFT index than subjects in the experimental group (p = 0.004). It is determined that there are no significant differences in the values of plaque index (p>0.05). The effect of different diseases or medications from their treatment, diet and fermentable carbohydrates in the etiology of dental caries cannot be observed outside the living conditions of subjects, their social epidemiologic status, age, habits, oral hygiene, fluoride use, etc.

The purpose of this study was to compare the effects of light-emitting diode (LED) irradiation and whole-body vibration (WBV) delivered either in isolation or combination (LED + WBV), warm-up (WU), and a control (C) treatment on performance during a sprint bicycle exercise. Ten cyclists performed a 30-second sprint cycle test under these conditions. The LED light was applied at 4 points bilaterally. Whole-body vibration consisted of 5 minutes of squats associated with WBV. LED + WBV consisted of WBV followed by LED therapy. Warm-up consisted of 17 minutes of moderate-intensity bicycle exercise. Control consisted of 10 minutes at rest. Blood lactate (BL) and ammonia (BA) levels and skin temperature (ST) were determined. Peak power (842 ± 117 vs. 800 ± 106 vs. 809 ± 128 W [p = 0.02 and p = 0.01]), relative power (12.1 ± 1.0 vs. 11.5 ± 0.9 vs. 11.6 ± 1.0 W·kg [p = 0.02 and p = 0.02]), and relative work (277 ± 23 vs. 263 ± 24 vs. 260 ± 23 J·kg [p = 0.02 and p = 0.003]) were higher in the WU group compared with the control and LED groups. In the LED + WBV group, peak (833 ± 115 vs. 800 ± 106 W [p = 0.02]) and relative (11.9 ± 0.9 vs. 11.5 ± 0.9 W·kg [p = 0.02]) power were higher than those in the control group, and relative work (272 ± 22 vs. 260 ± 23 J·kg [p = 0.02]) were improved compared with the LED group. There were no differences for BL, BA, and ST. The findings of this study confirmed the effectiveness of a warm-up as a preparatory activity and demonstrated that LED + WBV and WBV were as effective as WU in improving cyclist performance during a sprint bicycle exercise.

The aim of this study was to establish how reliable a given tympanogram is in predicting the presence or absence of a middle ear effusion, and to provide new views for the diagnostic information of tympanometry. The use of tympanometric gradient in addition to static admittance is the focus of this study. The authors enrolled 146 female and 129 male patients. The participants were allocated into groups as follow: Group A1 consisted of 50 healthy children. Group A2 consisted of 86 children with otitis media with effusion. Group B1 consisted of 85 healthy adults. Group B2 consisted of 54 adults with otitis media with effusion. All diagnostic otoscopic examination and tympanometry were performed in both ears. The authors analyzed the distribution of tympanograms in patients with otitis media with effusion and healthy controls. When the right and left ear canal volume of either children or adults with otitis media with effusion compared with healthy controls, no statistically significant different was observed (P > 0.05). On the other hand, the statistically significant difference was detected for the values of compliance, pressure and gradient of either children or adults with otitis media with effusion compared with healthy controls (P < 0.05). The authors found the values range from 0.01 to 1.52 mL gradients (mean least value 0.15 mL) in adults and the values range from 0.01 to 0.93 mL gradients (mean least value 0.10 mL) in children in the presence of otitis media with effusion. The authors think that tympanometric gradient may be useful to detect the otitis media with effusion.

Developmental trajectories of bullying and social dominance in youth.

Bullying is increasingly conceptualized as strategic behavior motivated by a desire to gain social dominance in the peer group. Cross-sectional research has shown that relative to their peers bullies are higher in social dominance as indexed by resource control, and are often perceived as powerful and "cool." However, research examining the developmental relationship between bullying and resource control is lacking. The present longitudinal study fills this gap in the literature. Using a three wave design, participants (N=394) were followed from late childhood into early adolescence. Joint trajectory analyses were used to test whether groups with distinct developmental trajectories of bullying and resource control can be identified, and how these trajectories are related. For both bullying and resource control three groups emerged (high, medium, and low), indicating that bullies and social dominants do not constitute one homogeneous group. More intense bullying is associated with higher levels of social dominance. Being consistently high in bullying is almost synonymous with being consistently high in resource control, whereas the reverse is not the case. Findings suggest that high bullying leads to the attainment of high social dominance, and do not support the view that children high in social dominance engage in bullying to maintain their dominant position. This study further underscores the need for interventions targeting mechanisms by which the peer group assigns social dominance to bullies. Copyright © 2012 Elsevier Ltd. All rights reserved.

The present paper had three purposes: (a) presenting normative data for the Rosenberg Self-esteem Scale in a Spanish sample, (b) studying whether there are significant sex or age differences in self-esteem, and (c) studying whether there are significant differences between a Control group with no psychological diagnosis and a group of social phobics. Of the total sample of 266 persons, 214 belonged to the Control group and 52 to the Social Phobic group. Item-total score correlations and alpha reliabilities supported the internal consistency of the scale. There were statistically significant differences between the Control and Social Phobic groups, but not by sex or age.

EMG median frequency changes in the neck-shoulder stabilizers of symptomatic office workers when challenged by different physical stressors.

The problem of work-related neck and upper limb disorders among computer users has been reported extensively in the literature, and commonly cited risk factors include static posture, speed and force of keyboard operation. The present study examined changes in median frequency (MF) of the neck-shoulder muscles in symptomatic and asymptomatic office workers when they were exposed to these three physical stressors. A quasi-experimental Case-Control design was used to examine MF changes in two groups of female office workers when they were subjected to controlled doses of computer work involving prolonged static posture, increased typing speed and increased typing force. The MF of four major neck-shoulder muscles were examined bilaterally and compared between groups. The MF changes over time-at-task did not clearly illustrate any muscle fatigue mechanism. However, Case Group consistently showed trends for higher MF than the Control Group, and this pattern was observed in response to all three physical stressors. The consistent group differences in MF suggest different muscle recruitment strategies between symptomatic and asymptomatic office workers. These results implied that symptomatic individuals had altered motor control, which may have important implications in understanding the etiology of work-related musculoskeletal disorders.

Motor imagery has emerged as a potential rehabilitation tool in stroke. The goals of this study were: 1) to develop a translated and culturally-adapted Brazilian-Portugese version of the Kinesthetic and Visual Motor Imagery Questionnaire (KVIQ20-P); 2) to evaluate the psychometric characteristics of the scale in a group of patients with stroke and in an age-matched control group; 3) to compare the KVIQ20 performance between the two groups. Test-retest, inter-rater reliabilities, and internal consistencies were evaluated in 40 patients with stroke and 31 healthy participants. In the stroke group, ICC confidence intervals showed excellent test-retest and inter-rater reliabilities. Cronbach's alpha also indicated excellent internal consistency. Results for controls were comparable to those obtained in persons with stroke. The excellent psychometric properties of the KVIQ20-P should be considered during the design of studies of motor imagery interventions for stroke rehabilitation.

This study examined the effects of a multicomponent exercise program on depression and quality of life in institutionalized older adults. A quasi-experimental pretest-posttest design was used. Participants were recruited from a publicly funded shelter home in Seremban, Negeri Sembilan Malaysia. The experimental group consisted of 23 volunteers 60 or older who performed 60 minutes of supervised exercise three times per week for 12 weeks. The control group consisted of 20 volunteers who continued with a sedentary lifestyle. At 12 weeks, the exercise group demonstrated an improvement in quality of life by 10.74% (p > 0.05) but not depression (-1.6%, p > 0.05). The control group demonstrated a decrease in both quality of life by 11.26% (p > 0.05) and level of depression by 17.7% (p > 0.05). This study suggests a multicomponent exercise program is a feasible intervention to improve quality of life in institutionalized older adults. Copyright 2010, SLACK Incorporated.

2012-01-01

The purpose of this study was to determine whether and when individuals with aphasia and healthy controls use lexical and prosodic information during on-line sentence comprehension. Individuals with aphasia and controls (n = 12 per group) participated in a self-paced listening experiment. The stimuli were early closure sentences, such as “While the parents watched(,) the child sang a song.” Both lexical and prosodic cues were manipulated. The cues were biased toward the subject- or object- of the ambiguous noun phrase (the child). Thus, there were two congruous conditions (in which both lexical cues and prosodic cues were consistent) and two incongruous conditions (in which lexical and prosodic cues conflicted). The results showed that the people with aphasia had longer listening times for the ambiguous noun phrase (the child) when the cues were conflicting, rather than consistent. The controls showed effects earlier in the sentence, at the subordinate verb (watched or danced). Both groups showed evidence of reanalysis at the main verb (sang). These effects demonstrate that the aphasic group was sensitive to the lexical and prosodic cues, but used them on a delayed time course relative to the control group. PMID:22143353

The purpose of this study was to identify the effects of foot reflexology on nausea, vomiting and fatigue in breast cancer patients undergoing chemotherapy. The research was a quasi-experimental study using a non-equivalent pre-post design and was conducted from Jan. 26, to Mar. 20, 2004. The subjects consisted of 34 patients with 18 in the experimental group and 16 in control group. A pretest and 2 posttests were conducted to measure nausea, vomiting and fatigue. For the experimental group, foot reflexology, which was consisted of 4 phases for 40 minutes, was given by a researcher and 4 research assistants. The collected data were analyzed by repeated measures ANOVA using the SPSS WIN 10.0 program. There was a statistically significant decrease in nausea, and vomiting in the experimental group compared to the control group over two different times. In addition, there was a statistically significant decrease in fatigue in the experimental group compared to the control group over two different times. Foot reflexology was effective on nausea, vomiting and fatigue in breast cancer patients receiving chemotherapy in this study. Therefore, foot reflexology can be usefully utilized as a nursing intervention in the field of cancer nursing for breast cancer patients receiving chemotherapy.

The purpose of this study was to compare the effects of scaling and Nd:YAG laser treatments with that of scaling alone on cementum and levels of Actinobacillus actinomycetemcomitans, Bacteroides forsythus, Porphyromonas gingivalis, and Treponema denticola. Study samples consisted of 14 patients, age 30 to 75 years, 8 females and 6 males, with a total of 150 periodontally involved sites with probing depth > or = 5 mm. Group A consisted of 100 pockets that were subdivided into 4 equal groups that were treated with conventional scaling and pulsed Nd:YAG laser using an optic fiber of 300 microns and 4 different power levels as follows: Group 1: P = 0.8 W, f = 10 Hz, E = 100 mJ/pulse; Group 2: P = 1.0 W, f = 1.0 Hz, E = 100 mJ/pulse; Group 3: P = 1.2 W, f = 12 Hz, E = 100 mJ/purse; and Group 4: P = 1.5 W, f = 15 Hz, E = 100 mJ/pulse. The time of each treatment was 60 sec per pocket in all 4 groups. Group B consisted of 50 pockets that were treated by conventional scaling alone and served as a control group. Microbiological samples from group A were collected before scaling; after scaling = before laser, just after laser, 2 weeks later, 6 weeks later, and 10 weeks later. Microbiological samples from group B were collected before scaling, after scaling, 6 weeks later, and 10 weeks later. Microbiological analysis of all samples was done by the Institute Für Angewandte Immunologie (IAI) method. The effects of laser on root surfaces were assessed by SEM examination and the sample consisted of 13 teeth from 5 different patients. Four sets of 3 teeth each were treated with Nd:YAG laser using 0.8, 1.0, 1.2, and 1.5 W, respectively. One tooth was just scaled and not treated with laser to serve as a control. Microbiological analysis of Group A samples indicated posttreatment reduction in levels of all 4 bacterial types tested compared to pretreatment levels and Group B controls. SEM examination of the specimens treated with Nd:YAG laser at different levels exhibited different features of root surface alterations.

To report our intrapartum experience with routine delivery at 38 weeks of gestation of A-2 diabetic pregnancies requiring primarily oral hypoglycemic therapy. This retrospective study consisted of 143 consecutive women with gestational diabetes not controlled with diet alone (A-2). Each underwent a routine trial of labor at 38 weeks of gestation. The preinduction condition of the cervix, need for oxytocin, and primary cesarean rates were primary endpoints. For comparison, a control group during that same period consisted of 137 consecutive diet-controlled diabetic (A-1) pregnancies with the same eligibility criteria who underwent expectant management at 38 weeks. The study group was more likely to have an unfavorable cervix (75% versus 45%; p < 0.001) and to require oxytocin (76% versus 56%; p < 0.001). Early onset meconium was less common in the study group (3.5% versus 13.1%; p < 0.01). Primary cesarean rates were low and not different between the study and control groups (12.7% versus 11.7%; p < 0.8). The only stillbirth was in the control group and was associated with a tight double nuchal cord encirclement. Mean birth weights and the frequency of birth weights > 4000 g were not different between groups. Shoulder dystocia, low Apgar scores, and admissions to the special care nursery were infrequent in either group. No respiratory difficulties requiring resuscitation or prolonged nursery care were encountered. Routine delivery at 38 weeks in an A-2 diabetic population is not associated with additional intrapartum morbidity or a greater need for cesarean delivery.

To determine the sociocultural factors that have effect on spontaneous abortion in Burdur, Turkey. Study was designed as case-control study. The case group consist of 257 women whose pregnancies ended with spontaneous abortion. The control group consisted of 514 women whose pregnancy continued since 22 weeks and more during the study. Chi-square, and backward LR logistic regression were utilized in analyses. In multifactorial-analyses it was determined that four factors (educational status of women, employment status of women, exposure to physical violence and non-receipt of ANC) created independent risk on spontaneous abortions. Pregnant women with these risk factors should be followed up more frequently and in a more qualified way in primary and secondary and tertiary health institutions.

To test the hypothesis that the use of Bendectin in pregnancy increases the risk of pyloric stenosis, we determined rates of antenatal Bendectin exposure among 325 infants with pyloric stenosis and among two control groups comprising infants with other defects; one consisted of 3,153 infants with other conditions, and the other, a subset of that group, consisted of 724 infants with defects that may have had their origins at any time in pregnancy. Comparisons between the cases and the two control series yielded estimated relative risks of 0.9 (95% confidence interval, 0.6 to 1.2) and 1.0 (0.7 to 1.4), respectively. The findings from this large case-control study suggest that Bendectin does not increase the risk of pyloric stenosis.

This study adapts a widely-used acquired equivalence paradigm to investigate how opioid-addicted individuals learn from positive and negative feedback, and how they generalize this learning. The opioid-addicted group consisted of 33 participants with a history of heroin dependency currently in a methadone maintenance program; the control group consisted of 32 healthy participants without a history of drug addiction. All participants performed a novel variant of the acquired equivalence task, where they learned to map some stimuli to correct outcomes in order to obtain reward, and to map other stimuli to correct outcomes in order to avoid punishment; some stimuli were implicitly “equivalent” in the sense of being paired with the same outcome. On the initial training phase, both groups performed similarly on learning to obtain reward, but as memory load grew, the control group outperformed the addicted group on learning to avoid punishment. On a subsequent testing phase, the addicted and control groups performed similarly on retention trials involving previously-trained stimulus-outcome pairs, as well as on generalization trials to assess acquired equivalence. Since prior work with acquired equivalence tasks has associated stimulus-outcome learning with the nigrostriatal dopamine system, and generalization with the hippocampal region, the current results are consistent with basal ganglia dysfunction in the opioid-addicted patients. Further, a selective deficit in learning from punishment could contribute to processes by which addicted individuals continue to pursue drug use even at the cost of negative consequences such as loss of income and the opportunity to engage in other life activities.

To evaluate the efficacy of autologous platelet rich plasma (PRP) in regeneration of bone and to assess clinical compatibility of the material in mandibular third molar extraction socket. To compare the healing of mandibular third molar extraction wounds with and without PRP. Group A consists of the 30 patients where PRP will be placed in the extraction socket before closure of the socket. Group B consists of 30 patients who will be the control group where the extraction sockets will be closed without any intra socket medicaments. The patients would be allocated to the groups randomly. Soft tissue healing was better in study site compared to control site. The result of the study shows rapid bone regeneration in the extraction socket treated with PRP when compared with the socket without PRP. Evaluation for bone blending and trabecular bone formation started earlier in PRP site compared to control, non PRP site. Also there was less postoperative discomfort on the PRP treated side. Autologous PRP is biocompatible and has significant improved soft tissue healing, bone regeneration and increase in bone density in extraction sockets.

The anti-obesity effects of mushroom chitosan prepared from Flammulina velutipes were investigated using an animal model with diet-induced obesity. In this study, 5-week-old imprinting control region (ICR) mice were divided into six groups of 10 mice each and fed different diets based on the MF powdered diet (standard diet) for 6 weeks: standard diet control group, high-fat diet control group (induced dietary obesity) consisting of the standard diet and 20% lard, and mushroom chitosan groups consisting of the high-fat diet with mushroom chitosan added at 100, 500, 1,000, and 2,000 mg/kg body weight. On the final day of the experiment, mean body weight was 39.1 g in the high-fat control group and 36.3 g in the 2,000 mg/kg mushroom chitosan group, compared to 35.8 g in the standard diet control group. In the mushroom chitosan groups, a dose-dependent suppression of weight gain and marked improvements in serum triglycerides, total cholesterol, LDL-cholesterol, and HDL-cholesterol were found. The mushroom chitosan groups showed fewer and smaller fat deposits in liver cells than the high-fat diet control group, and liver weight was significantly reduced. Glutamic oxaloacetic transaminase (GOT) and glutamate pyruvic transaminase (GPT), which are indices of the hepatic function, all showed dose-dependent improvement with mushroom chitosan administration. These results suggested that mushroom chitosan acts to suppress enlargement of the liver from fat deposition resulting from a high-fat diet and to restore hepatic function. The lipid content of feces showed a marked increase correlated with the mushroom chitosan dose. These findings suggest the potential use of mushroom chitosan as a functional food ingredient that contributes to the prevention or improvement of dietary obesity by inhibiting digestion and absorption of fats in the digestive tract and simultaneously promotes lipolysis in adipocytes.

The aim of this study was to investigate the prevalence and intensity of masticatory muscle and temporomandibular joint (TMJ) pain in Croatian war veterans with posttraumatic stress disorder (PTSD). The examined group consisted of 100 Croatian war veterans, in whom PTSD had previously been diagnosed. Patients were compared with 92 subjects who had not taken part in the war and in whom PTSD was excluded by psychiatric examination. The clinical examination consisted of palpation of the masticatory muscles, the prominent neck musculature, and TMJ. The examination technique used and the definition of items were previously tested for reliability and validity. 93% of the subjects with PTSD had masticatory muscle tenderness compared to 45.65% of the subjects in the control group (chi2 = 51.46, p < 0.0001). The most frequent painful location in the subjects with PTSD was the left lateral pterygoid site in 88%, and in subjects of the control group the right lateral pterygoid site in 28.26% of cases. The most painful location in the PTSD group was the left lateral pterygoid site in 72%, and in the control group the left posterior digastric in 4.35% of cases. 58% of the subjects with PTSD had TMJ tenderness compared to 3.26% of subjects in the control group (chi2 = 66.23, p < 0.0001). The most frequent painful location of TMJ in both groups was the left posterior capsule; in the PTSD group 38% and in subjects in the control group 2.17% of cases. The most painful location was the left posterior capsule in 28% of subjects with PTSD, while not one subject in the control group reported severe painful sensitivity. The very high frequency and intensity of pain in subjects with PTSD confirms the effect of stress on muscle and joint sensitivity, i.e. perception of pain.

Striving for group agency: threat to personal control increases the attractiveness of agentic groups

PubMed Central

Stollberg, Janine; Fritsche, Immo; Bäcker, Anna

2015-01-01

When their sense of personal control is threatened people try to restore perceived control through the social self. We propose that it is the perceived agency of ingroups that provides the self with a sense of control. In three experiments, we for the first time tested the hypothesis that threat to personal control increases the attractiveness of being part or joining those groups that are perceived as coherent entities engaging in coordinated group goal pursuit (agentic groups) but not of those groups whose agency is perceived to be low. Consistent with this hypothesis we found in Study 1 (N = 93) that threat to personal control increased ingroup identification only with task groups, but not with less agentic types of ingroups that were made salient simultaneously. Furthermore, personal control threat increased a sense of collective control and support within the task group, mediated through task-group identification (indirect effects). Turning to groups people are not (yet) part of, Study 2 (N = 47) showed that personal control threat increased relative attractiveness ratings of small groups as possible future ingroups only when the relative agency of small groups was perceived to be high. Perceived group homogeneity or social power did not moderate the effect. Study 3 (N = 78) replicated the moderating role of perceived group agency for attractiveness ratings of entitative groups, whereas perceived group status did not moderate the effect. These findings extend previous research on group-based control, showing that perceived agency accounts for group-based responses to threatened control. PMID:26074832

Studies assessing the transversal treatment changes caused by the functional regulator III (FR-3) are limited in number. This clinical study was planned to analyse the transversal effects of the FR-3 appliance therapy. The treatment group consisted of 17 patients (8 males and 9 females) with Class III malocclusion, who were treated with the FR-3 appliance. The control group consisted of 17 subjects (7 males and 10 females) with a normal occlusion. Mean ages of the subjects were 10.73 and 10.66 years in the treatment and control groups, respectively. Postero-anterior radiographs and stone casts were obtained before (T1) and after (T2) treatment/observation. The results of the Student's t-test comparing initial values showed that maxillary dentoalveolar and skeletal widths are significantly larger in the control group than those in the treatment group. At the end of the treatment, significant transverse increments occurred only at the dentoalveolar level of the maxilla. The transversal changes in the mandible were not statistically significant. Buccal shields of FR-3 did not stimulate the growth of maxillary apical base but caused an enhanced and supplementary widening of maxillary dental and alveolar structures.

The correlation between male sexual behavior and catecholamine levels in the medial preoptic area (MPOA) and arcuate nucleus (ARN) was studied in middle-aged rats. Male rats (18-19 months) were assigned to three groups: (1) Group MIE, consisting of rats showing mounts, intromissions, and ejaculations; (2) Group MI, consisting of rats showing mounts and intromissions, but no ejaculation; and (3) Group NC, consisting of non-copulators showing no sexual behavior. Young adult rats (4-5 months) displaying complete copulatory behavior were used as the control group. Dopamine (DA) and norepinephrine (NE) tissue levels in the MPOA and ARN were measured by high pressure liquid chromatography with electrochemical detection. There were no differences between MIE rats and young controls in DA or NE tissue levels in these two brain areas. Furthermore, no differences were found between the MI and NC groups in DA or NE tissue levels in either the MPOA or ARN. DA tissue levels in the MPOA and ARN in the MI and NC groups were significantly lower than those in the MIE group. NE tissue levels in the MPOA of the NC group were significantly lower than those in the MIE group, but no differences in NE tissue levels in the ARN were seen between the four groups. These results suggest that, in male rats, complete male sexual performance is related to tissue levels of DA, but not of NE, in the MPOA and/or ARN. Furthermore, ejaculatory behavior might be associated with critical DA tissue levels in the MPOA and/or ARN in middle-aged rats.

The 15-minute work break provides an opportunity to promote health, yet few studies have examined this part of the workday. We studied physical activity and sedentary behavior among office workers and compared the results of the Booster Break program with those of a second intervention and a control group to determine whether the Booster Break program improved physical and behavioral health outcomes. We conducted a 3-arm, cluster-randomized controlled trial at 4 worksites in Texas from 2010 through 2013 to compare a group-based, structured Booster Break program to an individual-based computer-prompt intervention and a usual-break control group; we analyzed physiologic, behavioral, and employee measures such as work social support, quality of life, and perceived stress. We also identified consistent and inconsistent attendees of the Booster Break sessions. We obtained data from 175 participants (mean age, 43 y; 67% racial/ethnic minority). Compared with the other groups, the consistent Booster Break attendees had greater weekly pedometer counts (P < .001), significant decreases in sedentary behavior and self-reported leisure-time physical activity (P < .001), and a significant increase in triglyceride concentrations (P = .02) (levels remained within the normal range). Usual-break participants significantly increased their body mass index, whereas Booster Break participants maintained body mass index status during the 6 months. Overall, Booster Break participants were 6.8 and 4.3 times more likely to have decreases in BMI and weekend sedentary time, respectively, than usual-break participants. Findings varied among the 3 study groups; however, results indicate the potential for consistent attendees of the Booster Break intervention to achieve significant, positive changes related to physical activity, sedentary behavior, and body mass index.

2013-08-01

The reaction time (RT) was assessed in two groups of healthy males, yoga group (M age = 29.0 yr.) and non-yoga or control group (M age = 29.0 yr.), with 35 participants each. The yoga group had an average experience of 6 months, while the control group was yoga-naïve. The yoga group was assessed in two sessions, (i) bhastrika pranayama or bellows breathing and (ii) breath awareness, while the control group had a single control session. The two experimental sessions, one with each type of breathing, and the control session consisted of pre- (5 min.), during (18 min.), and post-session epochs (5 min.). Assessments were made in the pre- and post-session epochs using a Multi-Operational Apparatus for Reaction Time. Following 18 min. of bhastrika pranayama there was a statistically significant reduction in number of anticipatory responses compared to before the practice. This suggests that the immediate effect of bhastrika pranayama is to inhibit unnecessary responding to stimuli.

A twelve-week controlled intervention trial was carried out to evaluate the effects of combined physical activity and dietary intervention on obesity and metabolic risk factors among employees of Universiti Putra Malaysia. Participants consisted of adults aged 25-55 years with no reported chronic diseases but with abdominal obesity. They were assigned to either a combined physical activity and dietary intervention group or a control group. The final sample consisted of 56 participants, with an equal number of 28 for each study group. No significant group effect was observed for any variable except for hip circumference (HC) and fasting plasma glucose (FPG). There was a significant increase in HC (p=0.007) and reduction in FPG (p=0.02) in the intervention group compared to the control group. In the intervention group, HC (p=0.002), triglycerides (TG) (p=0.0001), total cholesterol (TC) (p=0.0001), LDL cholesterol (LDLC) (p=0.0001) and FPG (p=0.005) were significantly reduced, while waist circumference (WC) (p=0.025) and the waist-to-hip ratio (WHR) (p=0.027) were significantly reduced in the control group. No significant change in steps/day or calorie intake'was observed in either group. Taken together, these data indicate that the combined physical activity and dietary intervention was not effective at improving diet or physical activity level. However, the intervention was effective in improving FPG among participants with abdominal obesity. The significant increase in HC in the interventions group warrants further study. These findings will be useful to further improve group-based intervention for the prevention and management of obesity.

We aimed to investigate the effect of alcohol abuse on the conjunctival flora. The cases were evaluated as two groups. The study group consisted of 55 heavy-drinking males diagnosed with alcohol abuse, while the control group consisted of 55 males without a history of alcohol abuse. Samples were taken from the inferior fornix conjunctiva with sterile cotton-tipped swabs (Amies transport medium) for culture. The samples were inoculated into blood agar, chocolate agar, eosine methylene blue agar and Saboraud-Dextrose agar (Oxoid/UK) with the dilution method. The microorganisms that grew in study group subjects were Coagulase Negative Staphylococcus (CNS) in 30 (54.5%), Staphylococcus aureus in 14 (25.5%), Moraxella spp. in 3 (5.5%), Streptococcus spp. in 3 (5.5), Bacillus spp. in 3 (5.5%), Corynebacterium spp. in 3 (5.5%), Candida spp. in 3 (5.5%), Haemophilus spp. in 2 (3.6%), Acinetobacter spp. in 2 (3.6%), Neisseria spp. in 1 (1.8%) and Micrococcus spp. in 1 (1.8%). The results for control group were CNS in 31 (56.4%), Bacillus spp. in 7 (12.7%), S. aureus in 5 (9.1%), and Corynebacterium spp. in 2 (3.6%). Moraxella spp., Streptococcus spp., Candida spp., Haemophilus spp., Acinetobacter spp., Neisseria spp. and Micrococcus spp. microorganisms grew in the conjunctival flora samples of the study group but not in the control group. S. aureus colonization was significantly higher in the study group than the control group (p < 0.05). The S. aureus colonization rate was statistically significantly higher in the study group. Some microorganisms only grew in the conjunctival flora samples of the study group. These findings indicate that the conjunctival flora in persons with chronic alcoholism is different than the normal population.

Breastfeeding has a positive influence on physical and mental development. Attention-deficit/hyperactivity disorder (ADHD) is a common neurobehavioral disorder with major social, familial, and academic influences. The present study aimed to evaluate whether ADHD is associated with a shorter duration of breastfeeding. In this retrospective matched study, children 6-12 years old diagnosed at Schneider's Children Medical Center (Petach Tikva, Israel) with ADHD between 2008 and 2009 were compared with two control groups. The first one consisted of healthy (no ADHD) siblings of ADHD children; the second control group consisted of children without ADHD who consulted at the otolaryngology clinic. A constructed questionnaire about demographic, medical, and perinatal findings, feeding history during the first year of life, and a validated adult ADHD screening questionnaire were given to both parents of every child in each group. In children later diagnosed as having ADHD, 43% were breastfed at 3 months of age compared with 69% in the siblings group and 73% in the control non-related group (p=0.002). By 6 months of age 29% of ADHD children were breastfed compared with 50% in the siblings group and 57% in the control non-related group (p=0.011). A stepwise logistic regression that included the variables found to be significant in univariate analysis demonstrated a significant association between ADHD and lack of breastfeeding at 3 months of age, maternal age at birth, male gender, and parental divorce. Children with ADHD were less likely to breastfeed at 3 months and 6 months of age than children in the two control groups. We speculate that breastfeeding may have a protective effect from developing ADHD later in childhood.

Liquid epoxide resins, solvents and solvent-modified epoxide resins, as well as hardeners for epoxide resins, appear to be skin and mucosa irritants of different intensity and possibly have allergenic properties. Therefore, it is required that the employees are qualified and industrial safety rules are followed when these substances are in use in the manufacturing process. Our study evaluated the state of dentition and analysed the loss of teeth in the workers of the laminate and composite materials department of aircraft factory. The research has been carried out in a group of 114 workers, which consisted of 88 men and 26 women 20 to 61 years old. The control group consisted of 41 workers of the administration department in the aircraft factory who did not have any contact with chemical compounds. The workers in the studied group are characterised as having an unsatisfactory state of dentition, as shown by the high rate of lost teeth (74 %). Statistically significant difference between the studied group and the control was found when the relationship between the number of lost molar teeth in women in the studied group and those in the control group is taken into consideration, a statistically significant difference appears to refer to teeth 46 and 27. The same statistically important correlation between men in the control and studied groups concerns teeth 16. The research data shows that incisor teeth are the least frequently extracted teeth in the whole population studied. Statistically significant differences can be noted for teeth 21 and 23 between the women in the control group and those in the studied one. Future studies are necessary to assess the potential relationship between the loss of teeth among workers of the department of laminate and composite materials of aircraft factory and their workplace.

The aim of this study was to evaluate the flexor and extensor muscle tone of the upper limbs in patients with spasticity or rigidity and to investigate the difference in hypertonia between spasticity and rigidity. The two experimental groups consisted of stroke patients and parkinsonian patients. The control group consisted of age and sex-matched normal subjects. Quantitative upper limb pendulum tests starting from both flexed and extended joint positions were conducted. System identification with a simple linear model was performed and model parameters were derived. The differences between the three groups and two starting positions were investigated by these model parameters and tested by two-way analysis of variance. In total, 57 subjects were recruited, including 22 controls, 14 stroke patients and 21 parkinsonian patients. While stiffness coefficient showed no difference among groups, the number of swings, relaxation index and damping coefficient showed changes suggesting significant hypertonia in the two patient groups. There was no difference between these two patient groups. The test starting from the extended position constantly manifested higher muscle tone in all three groups. In conclusion, the hypertonia of parkinsonian and stroke patients could not be differentiated by the modified pendulum test; the elbow extensors showed a higher muscle tone in both control and patient groups; and hypertonia of both parkinsonian and stroke patients is velocity dependent.

Case-control study. To determine whether metal ion concentrations are elevated in patients with spinal instrumentation. Studies have shown that serum and urinary levels of component metal ions are abnormally elevated in patients with total joint arthroplasties. Little is known of metal ion release and concentrations in patients with spinal instrumentation. The study group consisted of patients who had undergone spinal instrumentation for various spinal disorders with a variety of stainless steel implants, 5 to 25 years previously. A group of volunteers without metal implants were controls. All subjects were tested for serum nickel, blood chromium, and random urine chromium/creatinine ratio estimation. The study group consisted of 32 patients with retained implants and 12 patients whose implants had been removed. There were 26 unmatched controls. There was no difference in serum nickel and blood chromium levels between all 3 groups. The mean urinary chromium/creatinine ratio for patients with implants and those with implants removed was significantly greater than controls (P < 0.001). The difference between study subgroups was not significant (P = 0.16). Of several patient and instrumentation variables, only the number of couplings approached significance for correlation with the urine chromium excretion (P = 0.07). Spinal implants do not raise the levels of serum nickel and blood chromium. There is evidence that metal ions are released from spinal implants and excreted in urine. The excretion of chromium in patients with spinal implants was significantly greater than normal controls although lower where the implants have been removed. The findings are consistent with low-grade release of ions from implants with rapid clearance, thus maintaining normal serum levels. Levels of metal ions in the body fluids probably do not reach a level that causes late side-effect; hence, routine removal of the implants cannot be recommended.

Rotator cuff tears are a common cause of pain and disability of the shoulder. Information on the prevalence and identification of potential risk factors could help in early detection of rotator cuff tears and improve treatment outcome. Patients treated for a symptomatic rotator cuff tear on one side have a higher prevalence of rotator cuff tears and decreased shoulder function on the contralateral side compared with an age- and sex-matched group of healthy individuals. Case control study; Level of evidence, 3. One group consisted of 55 patients who had been arthroscopically treated on one shoulder for rotator cuff tear (tear group). In this group, the nonoperated contralateral shoulder was examined. For comparison, the matching shoulder in a control group consisting of 55 subjectively healthy individuals matched by age (±1 year) and sex to the tear group was included. Diagnosis of a rotator cuff tear was made by ultrasound. Outcomes were measured using the Constant score. The prevalence of supraspinatus tears was significantly higher (P < .0001) in the tear group (67.3%) compared with the control group (11.0%). The Constant score for the activities of daily living subscale, however, was significantly lower (18.4) in the tear group compared with the control group (19.9; P = .012). No other subcategory score nor the overall score showed a significant difference. There was a significantly higher tear prevalence in the tear group of patients aged between 50 and 59 years (P < .001) and 60 and 69 years (P = .004). No tear was diagnosed in the control group in individuals younger than 60 years. Patients treated for partial and full-thickness rotator cuff tears have a significantly higher risk of having a tear on the contralateral side and have noticeable deficits in their shoulder function regarding activities of daily living even if the tear is otherwise asymptomatic.

The correlation between dopamine (DA) and norepinephrine (NE) levels in the bed nucleus of the stria terminalis (BNST) and male sexual behavior was examined in middle-aged rats. Male rats (18-19 months) were divided into: (a) Group MIE, consisting of rats showing mounts, intromissions, and ejaculations; (b) Group MI, composed of rats showing mounts and intromissions, but no ejaculation; and (c) Group NC, consisting of noncopulators. Young adult rats (4-5 months) displaying complete copulatory behavior were used as the control. Tissue levels of DA, NE, and DA metabolites in the BNST were measured by high-pressure liquid chromatography. DA, but not NE, levels in MIE rats were significantly lower than those in young controls. DA and NE levels in MIE rats were significantly higher than those in NC rats. These results suggest that DA and NE in the BNST might play an important role in the control of male sexual behavior in middle-aged rats.

Research on neural basis of inhibitory control has been extensively conducted in various parts of the world. It is often implicitly assumed that neural basis of inhibitory control is universally similar across cultures. Here, we investigated the extent to which culture modulated inhibitory-control brain activity at both cultural-group and cultural-value levels of analysis. During fMRI scanning, participants from different cultural groups (including Caucasian-Americans and Japanese-Americans living in the United States and native Japanese living in Japan) performed a Go/No-Go task. They also completed behavioral surveys assessing cultural values of behavioral consistency, or the extent to which one's behaviors in daily life are consistent across situations. Across participants, the Go/No-Go task elicited stronger neural activity in several inhibitory-control areas, such as the inferior frontal gyrus (IFG) and anterior cingulate cortex (ACC). Importantly, at the cultural-group level, we found variation in left IFG (L-IFG) activity that was explained by a cultural region where participants lived in (as opposed to race). Specifically, L-IFG activity was stronger for native Japanese compared to Caucasian- and Japanese-Americans, while there was no systematic difference in L-IFG activity between Japanese- and Caucasian-Americans. At the cultural-value level, we found that participants who valued being "themselves" across situations (i.e., having high endorsement of behavioral consistency) elicited stronger rostral ACC activity during the Go/No-Go task. Altogether, our findings provide novel insight into how culture modulates the neural basis of inhibitory control. Copyright © 2016 Elsevier Inc. All rights reserved.

The purpose of this study was to examine systematically our previous clinical impression regarding the prevalence of personality disorders in patients suffering from circadian rhythm sleep disorders (CRSD). We hypothesized that, in a group of patients suffering from CRSD, there would be a higher frequency of personality disorders than in a group of healthy controls. The experimental group consisted of CRSD patients diagnosed according to a clinical interview and actigraphic recordings. The control group consisted of healthy volunteers in whom CRSD had been ruled out by means of a self-administered questionnaire. Both groups were assessed for personality disorders using the MCMI, a diagnostic tool based on Millon's biopsychosocial theory of personality and the PRQ-R, a diagnostic tool based on the DMS-III-R. Both tests provided clear and significant support for the hypothesis that individuals suffering from CRSD are characterized to a greater extent by personality disorders than a control group. No specific characteristic pattern or profile of personality disorders was clearly detected. Correct early diagnosis and treatment of CRSD may improve afflicted individuals' adaptive capabilities and perhaps even prevent the development of a personality disorder. This suggests how important a greater awareness of CRSD on the part of the professional community may be.

Safwat, Osama; Elkateb, Mona; Dowidar, Karin; El Meligy, Omar

To evaluate the clinical changes in dentin of deep carious lesions in young permanent molars, following ozone application with and without the use of a remineralizing solution, using the stepwise excavation. The sample included 162 first permanent immature molars, showing deep occlusal carious cavities that were indicated for indirect pulp capping. Teeth were divided into 2 main groups according to the method of ozone treatment. Each group was further subdivided equally into test and control subgroups. Following caries excavation, color, consistency and DIAGNOdent assessments of dentin were evaluated after 6 and 12 months. Regarding dentin color and consistency, no significant differences were observed following ozone application, with and without a remineralizing solution. There were no significant differences between ozone treatment, and calcium hydroxide during the different evaluation periods, except in group I cases after 6 months, concerning the dentin color. The DIAGNOdent values were significantly reduced following ozone application, with or without a remineralizing solution, as well as between test and control cases in group I after 6 months. Ozone application through the stepwise excavation had no significant effect on dentin color and consistency in young permanent molars. DIAGNOdent was unreliable in monitoring caries activity.

Feelings of romanticism and self-esteem among pregnant adolescents, adolescent mothers, and a control group of nonpregnant, nonparenting adolescents were investigated. The Bachman Self-Esteem Scale (Bachman, O'Malley, & Johnston, 1978) and the Dean Romanticism Scale (Dean, 1961) were distributed to 649 U.S. female adolescents--255 pregnant adolescents, 121 adolescent mothers, and 273 teenagers in the control group. For romanticism, the results indicated a significant main effect for group (pregnant teens, teen mothers, and a control group consisting of nonpregnant, nonparenting teenagers) and ethnicity (White, Hispanic, African American, and Asian) but not for age (13 to 15 years and 16 to 19 years). The pregnant teens and teen mothers thus had a higher degree of romanticism than the control group did. For self-esteem, there was a significant main effect for race, but not for group or for age. This main effect was qualified by a significant interaction between ethnicity and age.

To evaluate the beneficial effects of green plantain-based diet on stool volume, frequency and weight gain as compared with a traditional yogurt-based diet in children with persistent diarrhea. In a prospective, in-hospital controlled trial, two different treatments were administered to a sample of 80 children of both sexes, with ages ranging from 1 to 28 months, who had experienced >or= 14 days of persistent diarrhea. The sample was divided into two groups of isocaloric (100 kcal/kg/d) diets: experimental and control, of 40 patients each. The experimental group was randomly given a-week treatment consisting of a 50 g/L of cooked green plantain-based diet. The control group was fed on a yogurt-based diet. Both groups were not statistically different at admission. Pathogens were isolated from stools in 21.2% and 25% of patients in the experimental and control groups respectively; Aeromonas hydrophilia and Shigela flexneri were the most frequently found bacteria. The experimental group fed on a green plantain diet had a significantly better response in: diminishing stool output and consistency (p < 0.002), stool weight, diarrhea duration (p < 0.001), and increasing daily body weight gain (p < 0.001) than the yogurt-based diet group. The average duration of diarrhea in the plantain-based diet group was 18 hours shorter (p < 0.005) and it also had lower cost (p < 0.005). Our results support the benefits of green plantain in the dietary management of persistent diarrhea in hospitalized children, in relation to diarrheal duration, weight gain and costs.

There is ample knowledge reported in the literature about the role of oxidative stress in asthma pathogenesis. It is also known that the interaction of reactive oxygen species with DNA may result in DNA strand breaks. The aim of this study was to investigate if montelukast monotherapy affects oxidative stress and DNA damage parameters in a population of pediatric asthma patients. Group I consisted of 31 newly diagnosed asthmatic patients not taking any medication, and group II consisted of 32 patients who had been treated with montelukast for at least 6 months. Forty healthy control subjects were also enrolled in the study. Plasma total oxidant status (TOS) and total antioxidant status (TAS) were measured to assess oxidative stress. DNA damage was assessed by means of alkaline comet assay. The patients in both group I and group II had statistically significant higher plasma TOS (13.1 ± 4 and 11.1 ± 4.1 μmol H2O2 equivalent/liter, respectively) and low TAS levels (1.4 ± 0.5 and 1.5 ± 0.5 mmol Trolox equivalent/liter, respectively) compared with the control group (TOS: 6.3 ± 3.5 μmol H2O2 equivalent/liter and TAS: 2.7 ± 0.6 mmol Trolox equivalent/liter; p < 0.05). DNA damage was 18.2 ± 1.0 arbitrary units (a.u.) in group I, 16.7 ± 8.2 a.u. in group II and 13.7 ± 3.4 a.u. in the control group. There were statistically significant differences only between group I and the control group (p < 0.05). According to the findings, montelukast therapy makes only minimal but not statistically significant improvement in all TOS, TAS and DNA damage parameters. © 2015 S. Karger AG, Basel.

The effects of 14 weeks of Kata techniques training on stereotypic behaviors of children with autism spectrum disorders (ASD) were investigated. The study included 30 eligible (diagnosed ASD, school age) children with ages ranging from 5 to 16 years whom they assigned to an exercise (n=15) or a no-exercise control group (n=15). Participants of the exercise group received Kata techniques instruction four times per week for 14 weeks (56 sessions). Stereotypy was assessed at baseline (pre-intervention), week 14 (post-intervention), and at one month follow up in both groups. Results showed that Kata techniques training significantly reduced stereotypy in the exercise group. Following participation in Kata techniques training, stereotypy decreased from baseline levels by a M of 42.54% across participants. Interestingly, after 30 days of no practice, stereotypy in the exercise group remained significantly decreased compared to pre-intervention time. The participants of the control group did not show significant changes in the stereotypy. Teaching martial arts techniques to children with ASD for a long period of time consistently decreased their stereotypic behaviors. Copyright © 2012 Elsevier Ltd. All rights reserved.

In an attempt to develop a short neuropsychological test battery five different tests of reaction time were assessed according to their ability to discriminate between HIV seropositive men and healthy controls. In all tests a patient group with clinical symptoms was slower than the control group. In the complex reaction time test, which has a large cognitive aspect, even a clinically "asymptomatic" group was slower than the control group. The movement test, a new test with a large motor component, identified most slow responders, defining approximately half of the patients with clinical symptoms and one third of the "asymptomatic" patients as such. A test battery consisting of three tests is suggested for serial assessment and screening.

Introduction. Bruxism is to press or grind teeth against each other in non-physiologic cases, when an individual does not swallow or chew. If not treated, teeth problems, stress, mental disorders, frequent night waking, and headache is expected. This research aimed to study the effect of hydroxyzine on treating bruxism of 2- to 14-year-old children admitted to the clinic of Bandar Abbas Children Hospital. Methodology. In this clinical trial, 143 children with the ages between 4-12 years were admitted to the Children Hospital and were divided randomly into test and control groups. The test group consisted of 88 hydroxyzine-treated children and the control group consisted of 55 children who used hot towels. Both groups were examined in some stages including the pre-test stages or the stage before starting treatments at two, four, and six weeks and four months after stopping the treatment. The effects of each treatment on reducing bruxism symptoms were assessed by a questionnaire. The data were analyzed by using SPSS in descriptive statistics, t-test, and ANOVA. Results. As far as bruxism severity was concerned, the results showed a significant difference between the test group members who received hydroxyzine and the control group members who received no medication. T-test results showed a statistically significant difference between the test and the control groups in the second post-test (four weeks later) (p. value ≤ 0.05). Mean of the scores of bruxism severity in the test group has changed significantly in the post-test (at two weeks, four weeks, and six weeks later) as compared to the pre-test. Whereas, as far as the response to the treatment, no significant difference was recorded between the control group and the test group 4 weeks after the treatment. Discussion. The results showed that prescribing hydroxyzine for 4 weeks had a considerable effect in diminishing bruxism severity between the test groups.

The purpose of this study was to investigate if multi-domain cognitive training, especially robot-assisted training, alters cortical thickness in the brains of elderly participants. A controlled trial was conducted with 85 volunteers without cognitive impairment who were 60 years old or older. Participants were first randomized into two groups. One group consisted of 48 participants who would receive cognitive training and 37 who would not receive training. The cognitive training group was randomly divided into two groups, 24 who received traditional cognitive training and 24 who received robot-assisted cognitive training. The training for both groups consisted of daily 90-min-session, five days a week for a total of 12 weeks. The primary outcome was the changes in cortical thickness. When compared to the control group, both groups who underwent cognitive training demonstrated attenuation of age related cortical thinning in the frontotemporal association cortices. When the robot and the traditional interventions were directly compared, the robot group showed less cortical thinning in the anterior cingulate cortices. Our results suggest that cognitive training can mitigate age-associated structural brain changes in the elderly. Trial Registration ClnicalTrials.gov NCT01596205 PMID:25898367

This study was designed to determine the levels of prolactin, leptin, osteopontin, and follistatin in workers chronically and subacutely exposed to lead compounds. The examined population consisted of three groups. The first group was composed of 56 male workers who were chronically exposed to lead for 13.38 ± 10.38 years. The second group served as a control group and consisted of 24 male administrative workers, while the third group included 32 male workers exposed to lead for 40 ± 3 days. The levels of leptin, osteopontin, and prolactin were significantly lower in the group of workers chronically exposed to lead than in the control group by 42%, 26%, and 41%, respectively. The levels of follistatin did not differ between those groups. The levels of all measured hormones did not change after a short-term exposure to lead compared to baseline. Chronic lead exposure is associated with significantly decreased level of prolactin, leptin, and osteopontin. Lead-induced changes in the levels of these hormones may disturb many functions of the human body, including the immune response, metabolism, reproduction, and bone turnover.

2012-01-01

Two hundred thirty-eight first-year college students were assessed using the Beck Depression Inventory (BDI). Thirty students meeting the BDI criteria for moderate to severe depression were randomly assigned to either a treatment or control group. The treatment group received four 90-minute group sessions of EFT (Emotional Freedom Techniques), a novel treatment that combines exposure, cognitive reprocessing, and somatic stimulation. The control group received no treatment. Posttests were conducted 3 weeks later on those that completed all requirements (N = 18). The EFT group (n = 9) had significantly more depression at baseline than the control group (n = 9) (EFT BDI mean = 23.44, SD = 2.1 versus control BDI mean = 20.33, SD = 2.1). After controlling for baseline BDI score, the EFT group had significantly less depression than the control group at posttest, with a mean score in the “nondepressed” range (P = .001; EFT BDI mean = 6.08, SE = 1.8 versus control BDI mean = 18.04, SE = 1.8). Cohen's d was 2.28, indicating a very strong effect size. These results are consistent with those noted in other studies of EFT that included an assessment for depression and indicate the clinical usefulness of EFT as a brief, cost-effective, and efficacious treatment.

Cohen's d was 2.28, indicating a very strong effect size. These results are consistent with those noted in other studies of EFT that included an assessment for depression and indicate the clinical usefulness of EFT as a brief, cost-effective, and efficacious treatment.

The purpose of this study was to evaluate the effects on immigrant couples' communication, intimacy, conflict and quality of life when using foot massage. The research design consisted of pre-and-post test consecutive experimental design through a nonequivalent control group. Data were collected July 6, 2009 to February 27, 2010. The 36 couples were divided into two groups, experimental and control with 18 couples in each group. Foot massage was applied twice a week for 6 weeks by the couples in the experimental group. There were statistically significant increases in communication (p=.011), intimacy (p<.001), quality of life (p=.017) between the couples in the experimental group compared to the control group. There was also a statistically significant decrease in conflict (p=.003) between the couples in the experimental group compared to the control group. Foot massage can be applied as a nursing intervention for improvement of marital relationship in immigrant couples.

An acceleration of the wound healing process expedites chronic wound patient's return to normal social environments significantly. Sildenafil, a cyclic guanosine monophosphate (cGMP)-dependent phosphodiesterase- 5 inhibitor has been shown to be a potent stimulator of angiogenesis through upregulation of cGMP. In our study, sildenafil was administered orally as a cost-effective supplement in the treatment of full thickness defects and chronic wounds in that manner with low incidence of side effects and morbidity. Randomly selected 72 Wistar-Albino rats were divided into the two groups, 36 rats in each group. Control group (n =36) was divided further into a secondary healing group consisting of 9 rats and a pathology group consisting of 27 rats (pathology group 1: 9 rats, 4th and 7th day of wound healing, pathology group 2: 9 rats, 10th and 14th day of wound healing, pathology group 3: 9 rats, 21st and 28th day of wound healing. Experimental group consisted of 36 rats which received sildenafil citrate (Viagra® Pfizer, Germany) for secondary wound healing to proceed. The average wound healing period in the control group was 17.89 days and in the sildenafil citrate administered group 14.56 days. The difference of the epithelialisation on full thickness defects were more prominent on days 5 and 11 postoperatively. In the sildenafil citrate applied group, on the 7th day, the defect was 25% smaller and on the 13th day, the defect contracted by 38%. In conclusion, we believe that sildenafil citrate administered orally is a cost- effective supplement in the treatment of full thickness defects and chronic wounds in that manner with low incidence of side effects and morbidity (Tab. 4, Fig. 7, Ref. 34).

2013-01-01

Background Intermediate cognitive phenotypes (ICPs) are measurable and quantifiable states that may be objectively assessed in a standardized method, and can be integrated into association studies, including genetic, biochemical, clinical, and imaging based correlates. The present study used neuropsychological measures as ICPs, with factor scores in executive functioning, attention, memory, fine motor function, and emotion processing, similar to prior work in schizophrenia. Methods Healthy control subjects (HC, n=34) and euthymic (E, n=66), depressed (D, n=43), or hypomanic/mixed (HM, n=13) patients with bipolar disorder (BD) were assessed with neuropsychological tests. These were from eight domains consistent with previous literature; auditory memory, visual memory, processing speed with interference resolution, verbal fluency and processing speed, conceptual reasoning and set-shifting, inhibitory control, emotion processing, and fine motor dexterity. Results Of the eight factor scores, the HC group outperformed the E group in three (Processing Speed with Interference Resolution, Visual Memory, Fine Motor Dexterity), the D group in seven (all except Inhibitory Control), and the HM group in four (Inhibitory Control, Processing Speed with Interference Resolution, Fine Motor Dexterity, and Auditory Memory). Limitations The HM group was relatively small, thus effects of this phase of illness may have been underestimated. Effects of medication could not be fully controlled without a randomized, double-blind, placebo-controlled study. Conclusions Use of the factor scores can assist in determining ICPs for BD and related disorders, and may provide more specific targets for development of new treatments. We highlight strong ICPs (Processing Speed with Interference Resolution, Visual Memory, Fine Motor Dexterity) for further study, consistent with the existing literature. PMID:19800130

The aim of the investigation was to evaluate of IL-1beta and PGE2 concentrations in gingival fluid, whole blood as well as IL-1beta, PGE2 production after Escherichia coli lipopolysaccharide stimulation in whole blood in women with preterm low birth weight (PLBW), as compared to the control group. A case-control study of 88 postpartum women aged 17 to 39 was performed. The case group consisted of 52 women with PLBW and the control group consisted of 36 women giving birth in time. Concentration of inflammatory mediators in gingival fluid, blood serum and IL-1beta, PGE2 production in whole blood after bacterial lipopolysaccharide stimulation were determined by means of immunoenzymatic method. The levels of IL-1beta and PGE2 in gingival fluid were significantly higher in all PLBW mothers (also PLBW primiparous) than in the control group. In addition in the primiparous with PLBW group significantly higher PGE2 concentration in blood serum was found compared to the primiparous controls. There were no significant differences between women with PLBW and the controls together with a significantly higher production of IL-1beta and PGE2 in whole blood after LPS stimulation in women with periodontitis and gingivitis compared to subjects with healthy periodontium. Such findings suggest that inflammatory mediator synthesis is mainly result of specific cells exposition to bacterial products. Therefore it seems that more frequent occurrence of the phenotype of hyperactive cells that synthesise these mediators is not responsible for PLBW.

The Eating Assessment Tool (EAT-10) is a 10-item self-administered questionnaire. It is a noninvasive tool to measure patients' perception of their swallowing problems. The purposes of the present study were to develop an Arabic version of the EAT-10 and to evaluate its validity, consistency, and reliability in the Arabic-speaking population with oropharyngeal dysphagia. This was a prospective study carried out at the Communication and Swallowing Disorders Unit, King Saud University, Riyadh, Saudi Arabia. The Arabic EAT-10 was administered to 138 patients with oropharyngeal dysphagia and 83 control subjects. Internal consistency and test-retest reliability were evaluated. Content and clinical validity were studied, and the EAT-10 results were compared across patients and control groups. The Arabic EAT-10 showed excellent internal consistency (Cronbach's α = 0.92). Also, good test-retest reliability was found for the total scores of the Arabic EAT-10 (intraclass correlation = 0.73). There was a significant difference in Arabic EAT-10 scores between the oropharyngeal dysphagia group and the control group (p < 0.001). This study demonstrated that the Arabic EAT-10 is a valid tool that can be used for screening of dysphagia-related problems in an Arabic-speaking population. © 2016 S. Karger AG, Basel.

This study investigates the importance of communication in surgery and how delivering preoperative patient education can lead to better health outcomes postoperatively, via promoting tolerable pain scores and minimizing the use of narcotics after surgery. Patients who underwent outpatient surgery were randomly divided into groups to compare the pain scores of those who received preoperative patient education, the experimental group, and those who did not receive any form of patient education, the control group. Two weeks before surgery, the experimental group subjects received oral and written forms of patient education consisting of how the body responds to pain, and how endorphins cause natural analgesia. Moreover, patients were educated on the negative effects narcotics have on endorphin production and activity, as well as mechanisms of non-opioid analgesics. Of the 69 patients in the experimental group, 90% declined a prescription for hydrocodone after receiving preoperative education two weeks prior to surgery. The control group consisted of 66 patients who did not receive preoperative patient education and 100% filled their hydrocodone prescriptions. Patients in both groups were offered and received gabapentin and celecoxib preoperatively for prophylaxis of postoperative pain unless they declined. The control groups were found to have average pain scores significantly greater (P <.05) than the experimental groups and also a significantly longer (P <.005) duration of pain. This study illustrates the power of patient education via oral, written and visual communication, which can serve as an effective means to minimize narcotic analgesia after surgery.

The effectiveness of an integrated conceptual approach to teaching middle school science: A mixed methods investigation

NASA Astrophysics Data System (ADS)

Frampton, Susan K.

This study was designed to compare the effectiveness of using traditional and integrated instructional strategies to increase student understanding of the core concepts of energy. There are mixed messages in the literature as to the success of using an integrated approach to teach science content, despite suggestions its use improves student achievement and attitudes toward science. This study used a mixed-method approach. The quantitative portion was a quasi-experimental non-equivalent control group design, and the qualitative portion included teacher journals, teacher interviews and student journals. There were three teacher participants, two in the treatment group from a district in Sussex County, Delaware. The third teacher participant, from a different district in Sussex County, Delaware was in the control group. The treatment group consisted of 180 students and the control group consisted of 124 students. The results of this study show that the treatment group had significantly less anxiety in science following the treatment, than students in the control group. The F value of 10.89 was significant at p = 0.001. Students in the treatment group also had more enjoyment of and motivation in science than did students in the control group. The F value of 25.025 was significant at a p = 0.000 for the subscale enjoyment of science. The F value of 14.1 was significant at a p = 0.000 for the subscale of motivation in science. Students in the treatment group performed significantly better on the achievement tests, the Integrated Summative Energy Assessment (ISEA) and the science portion of the Delaware State Testing Program (DSTP). The treatment group performed significantly better on the ISEA than did the control group, with an F value of 407.7 significant at p = 0.000. The treatment group performed significantly better on the science DSTP than the control group, with an F value of 65.81 which was significant at p = 0.000. The use of an integrated approach to science instruction decreases student anxiety, increases enjoyment of science and motivation in science more than a traditional approach to teaching science. The use of an integrated approach to science instruction increases student achievement on extended response assessments that measure integrated conceptual knowledge and increases student achievement on traditional summative assessments.

A stroke patient with hemiplegic gait is generally described as being slow and asymmetric. Body weight-supported treadmill training and backward gait training are recent additions to therapeutic gait trainings that may help improve gait in stroke patient with hemiplegic gait. Therefore, we examined the effect of progressive backward body weight-supported treadmill training on gait in chronic stroke patients with hemiplegic gait. Thirty subjects were divided to the experimental and control groups. The experimental group consisted of 15 patients and underwent progressive backward body weight-supported treadmill training. The control group consisted of 15 patients and underwent general treadmill gait training five times per week, for a total of four weeks. The OptoGait was used to analyze gait kinematics, and the dynamic gait index (DGI) and results of the 6-minute walk test were used as the clinical evaluation indicators. A follow-up test was carried out four weeks later to examine persistence of exercise effects. The experimental group showed statistically significant results in all dependent variables week four compared to the control group. However, until the eighth week, only the dependent variables, of affected step length (ASL), stride length (SL), and DGI differed significantly between the two groups. This study verified that progressive bodyweight-supported treadmill training had a positive influence on the temporospatial characteristics of gait and clinical gait evaluation index in chronic stroke patients.

To investigate whether the use of cognitive behavioural therapy in pulmonary rehabilitation addresses the depression and anxiety burden and thereby improves rehabilitation outcomes. Prospective controlled clinical trial. A total of 70 patients with chronic obstructive pulmonary disease who were referred to a community centre for pulmonary rehabilitation. Patients were allocated to either the control group, consisting of pulmonary rehabilitation alone, or to the treatment group, receiving pulmonary rehabilitation and an additional 6 sessions of group-based cognitive behavioural therapy. Assessments consisting of questionnaires and walk tests were conducted pre- and post-pulmonary rehabilitation. A total of 28 patients were enrolled. The cognitive behavioural therapy group had significant improvements in exercise capacity following pulmonary rehabilitation (mean change 32.9 m, p = 0.043), which was maintained at 3 months post-pulmonary rehabilitation (mean change 23.4 m, p = 0.045). Patients in the cognitive behavioural therapy group showed significant short-term improvements in fatigue, stress and depression (mean change 2.4, p = 0.016, 3.9, p = 0.024 and 4.3, p = 0.047, respectively) and a 3-month post-pulmonary rehabilitation improvement in anxiety score (mean change 3.1, p = 0.01). No significant changes were seen in the control group. The addition of cognitive behavioural therapy improved patients' physical, psychological and quality of life results. Cognitive behavioural therapy should be considered for inclusion in a pulmonary rehabilitation programme to enhance outcomes.

Research suggests that patients with a severe mental illness (SMI) are among the most social excluded in society. However, comparisons of social network composition and relationship satisfaction between SMI patients and a control group are rare. Our aim was to compare differences in size, satisfaction and composition of the social network between patients with SMI and a control group. Potential sociodemographic and clinical risk factors in relation to social network size in SMI patients were explored. The sample consisted of a control group ( N = 949) and SMI patients ( N = 211) who were under treatment in Dutch mental health care institutions. In these groups, network size, relationship satisfaction, sociodemographic and clinical (patients only) characteristics were assessed. Social network size was 2.5 times lower in SMI patients, which was also reflected in a lower relationship satisfaction. The composition of the social network of SMI patients differs from that of controls: patients' network seems to consist of a smaller part of friends. Different risk factors were associated with the impoverishment of the social network of family, friends and acquaintances of patients with SMI. SMI patients have very small networks compared to controls. This may be a problem, given the ongoing emphasis on outpatient treatment of SMI patients and self-dependence. This outcome advocates for more attention to social isolation of SMI patients and involvement of family in the treatment and aftercare of SMI patients.

This study aimed to explore the effect of standardized teaching ward rounds in clinical nursing on preventing hospital-acquired infection. The experimental group comprised 120 nursing students from our hospital selected between June 2010 and June 2012. The control group consisted of 120 nursing students selected from May 2008 to May 2010. Traditional teaching ward rounds for nursing education were carried out with the control group, while a standardized teaching ward round was carried out with the experimental group. The comprehensive application of nursing abilities and skills, the mastering of situational infection knowledge, and patient satisfaction were compared between the two groups. The applied knowledge of nursing procedures and the pass rate on comprehensive skill tests were significantly higher in the experimental group than in the control group (P < 0.05). The rate of mastery of sterilization and hygiene procedures was also higher in the experimental group than in the control group (P < 0.05). The patient satisfaction rate with infection control procedures in the experimental group time period was 98.09%, which was significantly higher than patient satisfaction in the control group time period (93.05%, P < 0.05). Standardized teaching ward rounds for nursing education expanded the knowledge of the nursing staff in controlling hospital-acquired infection and enhanced the ability of comprehensive application and awareness of infection control procedures.

This study was designed to examine the effects of a bereavement intervention program on levels of depression and life satisfaction in middle aged widows in Korea. A quasi-experimental design with non-equivalent control-group pretest-posttest was used. The subjects (control group, n = 10; intervention group, n = 17) were bereaved less than 6 months in G City and J Province, Korea. The bereavement intervention program consisted of Dan-jeon breathing, self-help group activities and a health examination. The experimental group attended 10 sessions of a bereavement intervention program. The control group had a health examination without the intervention program. For both groups, the level of depression and life satisfaction levels were measured before and after the experiment. The decrement of depression level in the experimental group was significantly greater than in the control group (p<.001). The increment in life satisfaction in the experimental group was significantly greater than in the control group (p<.001). The results suggested that the bereavement intervention program was effective in decreasing level of depression and in increasing the life satisfaction of widows. Accordingly, a bereavement intervention program can be applied as an intervention to help widows.

The purpose of this study was to investigate the consistency of working length control between hand instrumentation in comparison to engine driven Mtwo nickel-titanium rotary files. Forty extracted maxillary molars were selected and divided onto two parallel groups. The working lengths of the mesiobuccal root canals were estimated. The teeth were fixed in a phantom head. The root canal preparation was carried out group 1 (n=20) with hand K-files, (VDW, Munich, Germany) and group 2 (n=20) with Mtwo instruments (VDW, Munich, Germany). Vestibulo-oral and mesio-distal directional x-ray images were taken before the preparation with #10 K-file, inserted into the mesiobuccal root canal to the working length, and after preparation with #25, #30 and #40 files. Working lenght changes were detected with measurements between the radiological apex and the instrument tips. In the Mtwo group a difference in the working competency (p<0.05) could be noticed only in the vestibulo-oral direction from #10 to #40 file. The hand instrument group showed a significant difference in working length competency for each larger file size (p<0.05) (ANOVA). Regression analysis in the hand instrumentation group indicated a working length decrease with a mean of 0,2 mm after each consecutive file size (p<0.01). The outcome of our trial indicated a high consistency in working length control for root canal preparation under simulated clinical condition using Mtwo rotary files. Mtwo NiTi rotary file did therefore proved to be more accurate in comparison to the conventional hand instrumentation.

This study examined the effects of text message content (generic vs. culturally tailored) on the login rate of an Internet physical activity program in Hong Kong Chinese adolescent school children. A convenience sample of 252 Hong Kong secondary school adolescents (51% female, 49% male; M age = 13.17 years, SD = 1.28 years) were assigned to one of 3 treatments for 8 weeks. The control group consisted of an Internet physical activity program. The Internet plus generic text message group consisted of the same Internet physical activity program and included daily generic text messages. The Internet plus culturally tailored text message group consisted of the Internet physical activity program and included daily culturally tailored text messages. Zero-inflated Poisson mixed models showed that the overall effect of the treatment group on the login rates varied significantly across individuals. The login rates over time were significantly higher in the Internet plus culturally tailored text message group than the control group (β = 46.06, 95% CI 13.60, 156.02; p = .002) and the Internet plus generic text message group (β = 15.80, 95% CI 4.81, 51.9; p = .021) after adjusting for covariates. These findings suggest that culturally tailored text messages may be more advantageous than generic text messages on improving adolescents' website login rate, but effects varied significantly across individuals. Our results support the inclusion of culturally tailored messaging in future online physical activity interventions.

Syphilis serofast reaction (SSR) is common in clinical work. From June 2005 to May 2009, 1208 syphilis patients were chosen for research by the Xiamen Center of Clinical Laboratory in China. Serologic tests were performed with toluidine red unheated serum test (TRUST) and Treponema pallidum particle agglutination (TPPA). Then, T. pallidum-specific IgM antibody (TP-IgM) was detected with fluorescent treponemal antibody absorption (FTA-Abs) and TPPA. In this study, patients were divided into the following experimental groups according to the results of TRUST and TPPA: (1) the SSR group consisted of 411 cases with (+) TRUST and (+) TPPA, and without clinical manifestations after 1 year of recommended syphilis treatment; (2) the serum cure group, which was further subdivided into group A consisting of 251cases with (-) TRUST and (+) TPPA; (3) group B consisting of 546 cases with (-) TRUST and (-) TPPA; and (4) the blood donor control group which consisted of 100 cases. We demonstrated that a total of 136 cases (33.09%) of 411 SSR patients were TP-IgM positive by TPPA, and this percentage was markedly higher than that in serum cure group A (9.16%). FTA-Abs analyses revealed similar results. All samples in serum cure group B and the control group were TP-IgM negative, which is identical to our previous report. The present study also indicated that the TP-IgM positive rate was not significantly different among patients with different ages, genders, and clinical phases after 1 year of recommended therapy. From the total of 1208 syphilis patients, 289 were randomly selected for TP-DNA detection by fluorescence quantitative polymerase chain reaction, and the positive rate of TP-DNA was 32.53%, which was slightly higher than that of FTA-Abs TP-IgM, and no statistically significant difference by chi-square tests, indicating the TP-DNA result is preferably consistent with FTA-Abs and supporting our deduction that TP-IgM could be used as a serologic marker for the relapse and infection of syphilis.

Nailfold capillaroscopy (NFC) is a non-invasive diagnostic test that is mostly used for early diagnosis of collagen tissue diseases (CTDs). We aimed to evaluate whether NFC findings could be a clue for discriminating idiopathic interstitial lung diseases (ILD) from CTD associated ILDs (CTD-ILD). Additionally it was aimed to determine whether NFC could be helpful in discriminating usual interstitial pneumonia (UIP) pattern from non-specific interstitial pneumonia (NSIP) pattern. We grouped patients into three main groups: 15 CTD-ILD, 18 idiopathic ILD, and 17 patients in the control group. The CTD-ILD group was split into two subgroups: 8 patients with Sjögren's syndrome (SJS)-associated ILD and 7 with rheumatoid arthritis (RA)-associated ILD. The idiopathic-ILD group consisted of 10 idiopathic NSIP and 8 IPF patients. The control group consisted of 10 SJS and 7 RA patients without lung disease. None of the patients were on acute exacerbation at the time of examination, and none had Reynaud's phenomenon. Mean capillary density was significantly reduced only in the CTD-ILD group as compared to the control group (p= 0.006). In subgroup analysis, it was determined that RA-ILD, IPF, and SJS-ILD subgroups had more severe capillaroscopic abnormalities. Mean capillary density in patients with the UIP pattern was reduced compared to patients with the NSIP pattern and those in the control group; p values were 0.008 and < 0.001, respectively. This study is to be the first describing and comparing the nailfold capillaroscopic findings of patients with NSIP and UIP patterns. NFC findings can be helpful in discriminating UIP patterns from NSIP patterns. But to show its role in differentiating idiopathic disease, more studies with more patients are needed.

To compare the dietary habits between colorectal neoplasia patients, their first-degree relatives, and unrelated controls. From July 2008 to April 2011, we collected epidemiological data relevant to colorectal cancer from patients with colorectal neoplasias, their first-degree relatives, and also from a control group consisting of people referred for colonoscopy with a negative family history of colorectal cancer and without evidence of neoplasia after colonoscopic examination. The first-degree relatives were divided into two groups following the colonoscopic examination: (1) patients with neoplasia or (2) patients without neoplasia. Dietary habits of all groups were compared. A χ (2) test was used to assess the association between two dichotomous categorical variables. The study groups consisted of 242 patients with colorectal neoplasias (143 men, 99 women; mean age: 64 ± 12 years) and 160 first-degree relatives (66 men, 94 women; mean age: 48 ± 11 years). Fifty-five of the first-degree relatives were found to have a neoplastic lesion upon colonoscopy, while the remaining 105 were without neoplasia. The control group contained 123 individuals with a negative family history for neoplastic lesions (66 men, 57 women; mean age: 54 ± 12 years). Two hypotheses were tested. In the first, the dietary habits of first-degree relatives with neoplasia were more similar to those of patients with neoplasia, while the dietary habits of first-degree relatives without neoplasia were similar to those of the control group. In the second, no sex-related differences in dietary habits were expected between the particular groups. Indeed, no significant differences were observed in the dietary habits between the groups of patients, controls and first-degree relatives with/without neoplastic lesions. Nevertheless, statistically significant sex-related differences were observed in all groups, wherein women had healthier dietary habits than men. In all groups examined, women had healthier dietary habits than men. Modification of screening guidelines according to sex may improve the efficiency of screening programs.

LSS is a degenerative arthritic disease in the spine that results in decreasing function, impaired balance, and gait deficit, with increased levels of leg and back pain. This physical impairment may result in an increased risk of fall later in the disease process, as shown in KOA. However, there has been no study regarding the association between the risk of a fall and LSS. The study was an age- and weight-matched case control study consisting of two groups: one group consisting of 40 patients with LSS who were scheduled to undergo spine surgery (LSS group) and the other group consisting of 40 patients with advanced osteoarthritis in both knees, scheduled to undergo TKA on both knees (KOA group). For both groups, four functional mobility tests, such as a Six-Meter-Walk Test (SMT), Sit-to-Stand test (STS), Alternative-Step Test (AST), and Timed Up and Go Test (TUGT), were performed. There was no difference in demographic data between both groups except for body mass index. For the SMT and STS, the patients in the LSS group spent significantly more time performing these tests than the patients in the KOA. For the AST, however, patients in the KOA group presented a statistically worse performance in functional mobility, compared with the LSS group. The mean TUGT time was not statistically different between the two groups. The current study highlights that patients with symptomatic LSS have a risk of a fall comparable with the patients who had degenerative KOA based on the results of functional mobility tests (SMT, STS, AST, and TUGT).

We aimed to assess psychometric properties, including internal consistency, reliability, and clinical validity of the Danish version of the Voice Handicap Index (VHI). A cross-sectional survey study was carried out. For validation, the existing nonvalidated Danish version of the VHI was used. Data from 208 patients with voice disorders of different etiology (neurogenic, functional, and structural) and a control group of 85 vocally healthy individuals were included. A test-retest reliability analysis of 42 patients and 45 control persons was performed. The internal consistency, test-retest reliability, and clinical validity of the questionnaire were assessed. Internal consistency was high with a Cronbach α >0.90 for both the patient and control group. Test-retest reliability measured as intraclass correlation coefficient was good with 0.93 (95% confidence interval [95% confidence interval]: 0.87-0.96) for patients and 0.78 (95% confidence interval: 0.63-0.87) for the control group which indicates sufficient reliability of the questionnaire. The Danish VHI has good clinical validity as it has a strong correlation between patient's perception of the severity of their voice disorder and the VHI score from the Spearman correlation of 0.69. The existing Danish version of the VHI has been thoroughly validated and found to be in line with the original VHI from Jacobsen et al. It showed good internal consistency, test-retest reliability, and clinical validity. It is suitable for use in daily practice and in research projects as it is able to assess patients' perception of their voice disorder severity. Copyright © 2018 The Voice Foundation.

The Dysphagia Handicap Index (DHI) is one of the instruments used for measuring a dysphagic patient's self-assessment. In some ways, it reflects the patient's quality of life. Although it has been recognized and widely applied in English speaking populations, it has not been used in its present forms in Persian speaking countries. The purpose of this study was to adapt a Persian version of the DHI and to evaluate its validity, consistency, and reliability in the Persian population with oropharyngeal dysphagia. Some stages for cross-cultural adaptation were performed, which consisted in translation, synthesis, back translation, review by an expert committee, and final proof reading. The generated Persian DHI was administered to 85 patients with oropharyngeal dysphagia and 89 control subjects at Zahedan city between May 2013 and August 2013. The patients and control subjects answered the same questionnaire 2 weeks later to verify the test-retest reliability. Internal consistency and test-retest reliability were evaluated. The results of the patients and the control group were compared. The Persian DHI showed good internal consistency (Cronbach's alpha coefficients range from 0.82 to 0.94). Also, good test-retest reliability was found for the total scores of the Persian DHI (r=0.89). There was a significant difference between the DHI scores of the control group and those of the oropharyngeal dysphagia group (P‹0.001). The Persian version of the DHI achieved Face and translation validity. This study demonstrated that the Persian DHI is a valid tool for self-assessment of the handicapping effects of dysphagia on the physical, functional, and emotional aspects of patient life and can be a useful tool for screening and treatment planning for the Persian-speaking dysphagic patients, regardless of the cause or the severity of the dysphagia.

The aim of this study was to evaluate the clinical efficacy of submandibular gland transfer for the prevention of xerostomia after radiotherapy for nasopharyngeal carcinoma. Using the randomized controlled clinical research method, 65 patients with nasopharyngeal carcinoma were randomly divided into an experimental group consisting of 32 patients and a control group consisting of 33 patients. The submandibular glands were averted to the submental region in 32 patients with nasopharyngeal carcinoma before they received conventional radiotherapy; a lead block was used to shield the submental region during therapy. Prior to radiotherapy, the function of the submandibular glands was assessed using imaging. Submandibular gland function was measured using 99mTc radionuclide scanning at 60 months after radiotherapy. The data in the questionnaire regarding the degree of xerostomia were investigated and saliva secretion was measured at 3, 6, 12, and 60 months after radiotherapy. In addition, the 5-year survival rate was calculated. After follow-up for 3, 6, and 12 months, the incidence of moderate to severe xerostomia was significantly lower in the experimental group than in the control group. The average amount of saliva produced by the experimental and control groups was 1.60 g and 0.68 g, respectively (P<0.001). After follow-up for 60 months, the uptake and secretion functions of the submandibular glands in the experimental group were found to be significantly higher than in the control group (P<0.001 and P<0.001, respectively). The incidence of moderate or severe xerostomia was significantly lower than in the control group (15.4% and 76.9%, respectively; P<0.001). The 5-year survival rates of the experimental group and the control group were 81.3% and 78.8%, respectively, and there was no significant difference between the two groups (P=0.806). After a 5 year follow-up period involving 32 patients who had their submandibular glands transferred for the prevention of xerostomia after radiotherapy for nasopharyngeal carcinoma, we found that clinical efficacy was good. This approach could improve the quality of life of nasopharyngeal carcinoma patients after radiotherapy and would not affect long-term treatment efficacy.

Women with lifelong vaginismus (N=117) were randomly assigned to cognitive-behavioral group therapy, cognitive-behavioral bibliotherapy, or a waiting list. Manualized treatment comprised sexual education, relaxation exercises, gradual exposure, cognitive therapy, and sensate focus therapy. Group therapy consisted of ten 2-hr sessions with 6 to 9 participants per group. Assistance with minimal-contact bibliotherapy consisted of 6 biweekly, 15-min telephone contacts. Twenty-one percent of the participants left the study before posttreatment assessment. Intent-to-treat analysis revealed that successful intercourse at posttreatment was reported by 14% of the treated participants compared with none of the participants in the control condition. At the 12-month follow-up 21% of the group therapy participants and 15% of the bibliotherapy participants, respectively, reported successful intercourse. Cognitive-behavioral treatment of lifelong vaginismus was thus found to be efficacious, but the small effect size of the treatment warrants future efforts to improve the treatment.

Background Tobacco dependence management is a multi-component intervention that includes pharmacological treatments such as Nicotine Substitution Therapy (NST) or bupropion, and psychological therapy. There are some preliminary reports on topiramate efficacy for tobacco dependence. The aim of this study is to determine whether topiramate is as effective as the standard NST treatment for tobacco cessation at 1-year follow-up in patients with depression. Method/design Design: A randomised, controlled trial involving two groups, one of which is the control group consisting of patients on the standard pharmacological treatment for tobacco cessation (NST) and the other is the intervention group consisting of patients on topiramate as pharmacological treatment. Setting: 29 primary care health centres in the city of Zaragoza, Spain. Sample: 180 patients, aged 18–65 years, diagnosed with major depression, smoke more than 20 cigarettes/day, who have voluntarily asked for tobacco cessation therapy. Intervention: A multi-component programme for tobacco cessation is offered to all of the patients in the study. This programme is made up of pharmacological therapy + group cognitive-behavioural therapy. Pharmacological therapy consists of NST for the control group and topiramate (200 mg/day) for the intervention group. Psychological therapy is made up of 16 sessions of manualised group therapy. Measurements: Cessation will be assessed by patient self-declared abstinence, expired air carbon monoxide levels, and cotinine levels in saliva. Questionnaires on tobacco dependence, anxiety, depression, impulsiveness and self-efficacy will be administered. The interviewers will not know which group the patient belongs to (blind). The assessments will be carried out at baseline, D (cessation day) -1, D+1, weeks 1, 2, 3, 4, 6, 8, 10 and 13, and months 4, 5, 6, 8, 10 and 12. Main variables: Tobacco cessation rates and tobacco dependence. Analysis: The analysis will be per intent to treat. We will use the general linear models of the SPSS version 15 statistical package, to analyse the effect of the treatment on the result variable (tobacco cessation rate). Discussion It is necessary to develop new and more effective pharmacological treatments for tobacco cessation. This randomised clinical trial will determine whether topiramate is effective for tobacco cessation in patients with depression.

OBJECTIVE: To study the effectiveness of an intensive small group education and peer review programme aimed at implementing national guidelines on asthma/chronic obstructive pulmonary disease (COPD) on care provision by general practitioners (GPs) and on patient outcomes. DESIGN: A randomised experimental study with pre-measurement and post- measurement (after one year) in an experimental group and a control group in Dutch general practice. SUBJECTS AND INTERVENTION: Two groups of GPs were formed and randomised. The education and peer review group (17 GPs with 210 patients) had an intervention consisting of an interactive group education and peer review programme (four sessions each lasting two hours). The control group consisted of 17 GPs with 223 patients (no intervention). MAIN OUTCOME MEASURES: Knowledge, skills, opinion about asthma and COPD care, presence of equipment in practice; actual performance about peakflow measurement, non-pharmacological and pharmacological treatment; asthma symptoms (Dutch Medical Research Council), smoking habits, exacerbation ratio, and disease specific quality of life (QOL-RIQ). Data were collected by a written questionnaire for GPs, by self recording of consultations by GPs, and by a written self administered questionnaire for adult patients with asthma/COPD. RESULTS: Data from 34 GP questionnaires, 433 patient questionnaires, and recordings from 934 consultations/visits and 350 repeat prescriptions were available. Compared with the control group there were only significant changes for self estimated skills (+16%, 95% confidence interval 4% to 26%) and presence of peakflow meters in practice (+18%, p < 0.05). No significant changes were found for provided care and patient outcomes compared with the control group. In the subgroup of more severe patients, the group of older patients, and in the group of patients not using anti-inflammatory medication at baseline, no significant changes compared with the control group were seen in patient outcomes. CONCLUSION: Except for two aspects, intensive small group education and peer review in asthma and COPD care do not seem to be effective in changing relevant aspects of the provided care by GPs in accordance with guidelines, nor in changing patients' health status.

Psychological intimate partner violence (P-IPV) refers to verbal abuse from one partner to another and abuse of power or control from one partner to another. To date, no studies have examined the longitudinal course of P-IPV exposure among mothers or the effect that witnessing P-IPV can have on their children. Using latent class growth analysis, the current study identified five trajectory groups with the following intercept and growth characteristics: low stable, low-increasing, moderate-decreasing, high-decreasing, and consistently elevated. Membership in the four groups characterized by higher P-IPV exposure was predicted by maternal race and exposure to physical abuse. The children of mothers in the low-increasing and consistently elevated groups had elevated scores on the Internalizing and Externalizing scales of the Childhood Behavior Checklist. These findings remained after controlling for child sex, race, cumulative trauma exposure, and maternal depression.

Consistent, high-quality introductions to organic chemistry laboratory techniques effectively and efficiently support student learning in the organic chemistry laboratory. In this work, we developed and deployed a series of instructional videos to communicate core laboratory techniques and concepts. Using a quasi-experimental design, we tested the videos in five traditional laboratory experiments by integrating them with the standard pre-laboratory student preparation presentations and instructor demonstrations. We assessed the influence of the videos on student laboratory knowledge and performance, using sections of students who did not view the videos as the control. Our analysis of pre-quizzes revealed the control group had equivalent scores to the treatment group, while the post-quiz results show consistently greater learning gains for the treatment group. Additionally, the students who watched the videos as part of their pre-laboratory instruction completed their experiments in less time.

Several characteristics of sexual assault awareness programs for women are associated with meeting the goals of risk reduction. To date, the literature lacks an exploration of how single-sex programs affect women, particularly when they take a bystander intervention focus using women's risk recognition and avoidance as outcome measures. The purpose of this study was to investigate the effectiveness of The Women's Program (Foubert, 2011), a sexual assault awareness program geared toward women. Participants consisted of 103 undergraduate women attending a large, public university in the Midwest United States. Women in the treatment group viewed a presentation of The Women's Program, whereas the control group received no intervention. Consistent with hypotheses, program participants reported a greater ability to recognize risk cues, a greater willingness to engage in self-protective behaviors, and a greater level of perceived self-efficacy in handling threatening dating situations compared to the control group.

The ability to diagnose oral lichen planus (OLP) based on saliva analysis using THz time-domain spectroscopy and chemometrics is discussed. The study involved 30 patients (2 male and 28 female) with OLP. This group consisted of two subgroups with the erosive form of OLP (n = 15) and with the reticular and papular forms of OLP (n = 15). The control group consisted of six healthy volunteers (one male and five females) without inflammation in the mucous membrane in the oral cavity and without periodontitis. Principal component analysis was used to reveal informative features in the experimental data. The one-versus-one multiclass classifier using support vector machine binary classifiers was used. The two-stage classification approach using several absorption spectra scans for an individual saliva sample provided 100% accuracy of differential classification between OLP subgroups and control group.

To establish the efficacy of an internet based prevention program to reduce alcohol and cannabis use in adolescents. A cluster randomised controlled trial was conducted with 764 13-year olds from ten Australian secondary schools in 2007-2008. Half the schools were randomly allocated to the computerised prevention program (n=397), and half to their usual health classes (n=367). The Climate Schools: Alcohol and Cannabis prevention course is facilitated by the internet and consists of novel, evidence-based, curriculum consistent lessons aimed at reducing alcohol and cannabis use. Participants were assessed at baseline, immediately post, and at six months following the intervention. Compared to the control group, students in the intervention group showed significant improvements in alcohol and cannabis knowledge at the end of the course and the six month follow-up. In addition, the intervention group showed a reduction in average weekly alcohol consumption and frequency of cannabis use at the six month follow-up. No differences between groups were found on alcohol expectancies, cannabis attitudes, or alcohol and cannabis related harms. The course is acceptable, scalable and fidelity is assured. It increased knowledge regarding alcohol and cannabis, and decreased use of these drugs.

The aim of our study was to estimate whether the placement of cerclage in pregnancy to prevent preterm birth (PTB) is associated with higher incidence of intrapartum cervical lacerations. A retrospective cohort study was conducted on singleton pregnancies with risk factors for PTB. The study group consisted of women with either a history- or ultrasound-indicated cerclage placed between 12 and 24 weeks of gestation, while the control group consisted of women with similar risk factors for PTB but who did not receive a cerclage. Primary outcome was the incidence of intrapartum cervical lacerations. A sample size calculation was performed on the basis of the results of previous studies on cervical lacerations. We identified 134 women who had a cerclage placed in pregnancy. They were compared with 236 controls with no cerclage. Cases and controls had similar risk factors for cervical lacerations. Cervical lacerations occurred with similar frequencies in the cerclage and no-cerclage group (2.2 vs 1.3%, p = 0.78). There was no significant difference between the two groups for the risk of cervical lacerations (RR 1.76, 95% CI: 0.36-8.60). Cerclage placement during pregnancy is not associated with an increased risk of intrapartum cervical lacerations.

To evaluate the left ventricular twist characteristics in patients with type 2 diabetes by using two-dimensional speckle tracking imaging (STI). Ninety-three patients with type 2 diabetes admitted in Zhejiang Hospital from May 2012 to September 2013 were enrolled. According to left ventricular ejection fraction (LVEF), patients were divided into two groups: normal left ventricular systolic function group (group A, LVEF≥0.50, n=46) and abnormal left ventricular systolic function group (group B, LVEF <0.50, n=47). Forty-six healthy subjects were selected as normal controls. STI was applied to quantitatively analyze the left ventricular twist. Correlation of the peak of left ventricular twist angle (Peaktw), aortic valve closure time twist angle (AVCtw), and mitral valve opening time twist angle (MVOtw) with LVEF, Tei index, E/A, and E/e was evaluated. Consistency check for STI was conducted to assess its stability and reliability. The Peaktw, AVCtw, and MVOtw in group A were significantly elevated than those in normal controls (P<0.05). The Peaktw, AVCtw, and MVOtw in group B was lower than those in normal controls and group A (P<0.05). In diabetic patients, the Peaktw, AVCtw, MVOtw were positively correlated with LVEF (r=0.968, 0.966, 0.938;P<0.05) and E/A (r=0.798, 0.790, 0.788; P<0.05), and were negatively correlated with Tei index (r=-0.834, -0.811, -0.797; P<0.05) and E/e (r=-0.823, -0.805, -0.771; P<0.05). The agreement between measurers and within measurers of Peaktw was satisfactory (between measurers: R=0.957, bias=-0.1, 95% consistency limit=-2.8-2.7; within measurer: R=0.964, bias=-0.2, 95% consistency limits=-2.7-2.2). STI can be used for early recognition of abnormal changes of cardiac function in type 2 diabetic mellitus patients, with high stability and reliability.

SAGES FUSE curriculum provides didactic knowledge on OR fire prevention. The objective of this study is to evaluate the impact of an immersive virtual reality (VR)-based OR fire training simulation system in combination with FUSE didactics. The study compared a control with a simulation group. After a pre-test questionnaire that assessed the baseline knowledge, both groups were given didactic material that consists of a 10-min presentation and reading materials about precautions and stopping an OR fire from the FUSE manual. The simulation group practiced on the OR fire simulation for one session that consisted of five trials within a week from the pre-test. One week later, both groups were reassessed using a questionnaire. A week after the post-test both groups also participated in a simulated OR fire scenario while their performance was videotaped for assessment. A total of 20 subjects (ten per group) participated in this IRB approved study. Median test scores for the control group increased from 5.5 to 9.00 (p = 0.011) and for the simulation group it increased from 5.0 to 8.5 (p = 0.005). Both groups started at the same baseline (pre-test, p = 0.529) and reached similar level in cognitive knowledge (post-test, p = 0.853). However, when tested in the mock OR fire scenario, 70% of the simulation group subjects were able to perform the correct sequence of steps in extinguishing the simulated fire whereas only 20% subjects in the control group were able to do so (p = 0.003). The simulation group was better than control group in correctly identifying the oxidizer (p = 0.03) and ignition source (p = 0.014). Interactive VR-based hands-on training was found to be a relatively inexpensive and effective mode for teaching OR fire prevention and management scenarios.

The new methods of different administration times for the treatment of primary dysmenorrhea are more widely used clinically; however, no obvious mechanism has been reported. Therefore, an animal model which is closer to clinical evaluation is indispensable. A novel animal experiment with different administration times, based on the mice oestrous cycle, for primary dysmenorrhoea treatment was explored in this study. Mice were randomly divided into two parts (one-cycle and three-cycle part) and each part includes five groups (12 mice per group), namely, Jingqian Zhitong Fang (JQF) 6-day group, JQF last 3-day group, Yuanhu Zhitong tablet group, model control group, and normal control group. According to the one-way ANOVAs, results (writhing reaction, and PGF2α, PGE2, NO, and calcium ions analysis by ELISA) of the JQF cycle group were in accordance with those of JQF last 3-day group. Similarly, results of three-cycle continuous administration were consistent with those of one-cycle treatment. In conclusion, the consistency of the experimental results illustrated that the novel animal model based on mice oestrous cycle with different administration times is more reasonable and feasible and can be used to explore in-depth mechanism of drugs for the treatment of primary dysmenorrhoea in future.

Delay in ABR and CAEPs wave latencies in children with type 1DM indicates that there is abnormality in the neural conduction in DM patients. The duration of DM has greater effect on auditory function than the control of DM. Diabetes mellitus (DM) is a common endocrine and metabolic disorder. Evoked potentials offer the possibility to perform a functional evaluation of neural pathways in the central nervous system. To investigate the effect of type 1 diabetes mellitus (T1DM) on auditory brain stem response (ABR) and cortical evoked potentials (CAEPs). This study included two groups: a control group (GI), which consisted of 20 healthy children with normal peripheral hearing, and a study group (GII), which consisted of 30 children with type I DM. Basic audiological evaluation, ABR, and CAEPs were done in both groups. Delayed absolute latencies of ABR and CAEPs waves were found. Amplitudes showed no significant difference between both groups. Positive correlation was found between ABR wave latencies and duration of DM. No correlation was found between ABR, CAEPs, and glycated hemoglobin.

Practising target-shooting sport requires focused attention and motoric steadiness. A previous non-controlled pilot study suggests that children with impairing symptoms of attention-deficit/hyperactivity disorder (ADHD) benefit from participating in target-shooting sport in local shooting associations, as rated by parents and teachers. This study aims at examining if, and to which extent, target-shooting sport reduces parent- and teacher-reported severity of inattentiveness, hyperactivity, and impulsivity in children with attention difficulties, and if, and to which extend, target-shooting sport improves the children's wellbeing and quality of life. A mixed method approach is applied. A non-blinded, waiting list controlled study is combined with a case study, consisting of interviews and observations. The intervention consists of children practising target-shooting sport, by attending a local shooting association, once a week for six months, during regular school hours. Data from questionnaires (ADHD-RS, SDQ, Kidscreen-27), as well as a computerized continued performance test (Qb test), measure the children's activity and attention. The study includes 50 children in an intervention group and 50 children in a waiting list control group. The Qb test collects data from at least 20 children from the intervention group and at least 20 children from the waiting list control group. Data from the questionnaires and Qb-test is collected at baseline, and six months post intervention. In addition, a case study is carried out, consisting of interviews of at least five children from the intervention group, their parents, teachers and shooting instructors. Observations are carried out, when children are in school and while they are attending the local shooting association. The case study adds to an in-depth understanding of children's participation in target-shooting sports. At present, little is known about the effects and influence of practising target-shooting sport for children experiencing difficulties with inattentiveness, hyperactivity and impulsivity. This study is expected to contribute to an understanding of the influence of participating in target-shooting sports on inattentive, hyperactive and impulsive symptoms, and the effects on the children's psychological wellbeing and quality of life.

To investigate how suicide microblog users in China "act" and "speak" differently from other microblog users without suicide idea. The suicide group consisted of 31 Chinese microblog users identified as suicide via online information provided by a Sina microblog user, and the control group consisted of 30 active microblog users without suicide idea screened by using suicide-related psychological scales. The differences in 10 microblog use behavioral characteristics and 88 linguistic characteristics between the suicide group and the control group were compared with normality test and rank sum test respectively. In the behavioral characteristics, the suicide group used hyperlinks and "@" less frequently than the control group [0.04 (0.04) vs. 0.06 (0.04), P=0.029; 0.60 (0.27) vs. 0.69 (0.18), P=0.028], and was more self-focused [0.47 (0.25) vs. 0.30 (0.10), P=0.010]. In the linguistic characteristics, the suicide group showed less frequency in using measure word, work related word and apostrophe than the control group (P<0.05), and showed more frequency in using pronoun, personal pronoun, third person singular, non-specific pronoun, word expressing social experience, word expressing anxiety, word expressing exclusion, sexual word, religious word, second person singular, human being related word, negative emotion related word, anger related word, sadness or death related word (P<0.05). Suicides seemed to interact less with others, showed more self-concern and more negative expressions, use more cognitively exclusive, death-related, religion-related words, and use less work-related words. The results of this study might be helpful for the research on suicide among netizen.

Case-control studies to quantify oral cholera vaccine effectiveness (VE) often rely on neighbors without diarrhea as community controls. Test-negative controls can be easily recruited and may minimize bias due to differential health-seeking behavior and recall. We compared VE estimates derived from community and test-negative controls and conducted bias-indicator analyses to assess potential bias with community controls. From October 2012 through November 2016, patients with acute watery diarrhea were recruited from cholera treatment centers in rural Haiti. Cholera cases had a positive stool culture. Non-cholera diarrhea cases (test-negative controls and non-cholera diarrhea cases for bias-indicator analyses) had a negative culture and rapid test. Up to four community controls were matched to diarrhea cases by age group, time, and neighborhood. Primary analyses included 181 cholera cases, 157 non-cholera diarrhea cases, 716 VE community controls and 625 bias-indicator community controls. VE for self-reported vaccination with two doses was consistent across the two control groups, with statistically significant VE estimates ranging from 72 to 74%. Sensitivity analyses revealed similar, though somewhat attenuated estimates for self-reported two dose VE. Bias-indicator estimates were consistently less than one, with VE estimates ranging from 19 to 43%, some of which were statistically significant. OCV estimates from case-control analyses using community and test-negative controls were similar. While bias-indicator analyses suggested possible over-estimation of VE estimates using community controls, test-negative analyses suggested this bias, if present, was minimal. Test-negative controls can be a valid low-cost and time-efficient alternative to community controls for OCV effectiveness estimation and may be especially relevant in emergency situations.

To evaluate the influence of nandrolone decanoate on fracture healing and bone quality in normal rats. Male rats were assigned to four groups (n=28/group): Control group consisting of animals without any intervention, Nandrolone decanoate (DN) group consisting of animals that received intramuscular injection of nandrolone decanoate, Fracture group consisting of animals with a fracture at the mid-diaphysis of the femur, and Fracture and nandrolone decanoate group consisting of animals with a femur fracture and treatment with nandrolone decanoate. Fractures were created at the mid-diaphysis of the right femur by a blunt trauma and internally fixed using an intramedullary steel wire. The DN was injected intramuscularly twice per week (10 mg/kg of body mass). The femurs were measured and evaluated by densitometry and mechanical resistance after animal euthanasia. The newly formed bone and collagen type I levels were quantified in the callus. The treated animals had longer femurs after 28 days. The quality of the intact bone was not significantly different between groups. The bone callus did show a larger mass in the treated rats. The administration of nandrolone decanoate did not affect the quality of the intact bone, but might have enhanced the bone callus formation.

The objective of this study is to systematically evaluate the effects of a tissue-engineered bone complex for maxillary sinus augmentation in a canine model. Twelve sinus floor augmentation surgeries in 6 animals were performed bilaterally and randomly repaired with the following 3 groups of grafts: group A consisted of tissue-engineered osteoblasts/beta-TCP complex (n=4); group B consisted of beta-TCP alone (n=4); group C consisted of autogenous bone obtained from iliac crest as a positive control (n=4). All dogs had uneventful healings following the surgery. Sequential polychrome fluorescent labeling, maxillofacial CT, microhardness tests, as well as histological and histomorphometric analyses indicated that the tissue-engineered osteoblasts/beta-TCP complex dramatically promoted bone formation and mineralization and maximally maintained the height and volume of elevated maxillary sinus. By comparison, both control groups of beta-TCP or autologous iliac bone showed considerable resorption and replacement by fibrous or fatty tissue. We thus conclude that beta-TCP alone could barely maintain the height and volume of the elevated sinus floor, and that the transplantation of autogenous osteoblasts on beta-TCP could promote earlier bone formation and mineralization, maximally maintain height, volume and increase the compressive strength of augmented maxillary sinus. This tissue engineered bone complex might be a better alternative to autologous bone for the clinical edentulous maxillary sinus augmentation. Copyright (c) 2009 Elsevier Inc. All rights reserved.

Individuals spontaneously categorise other people on the basis of their gender, ethnicity and age. But what about the emotions they express? In two studies we tested the hypothesis that facial expressions are similar to other social categories in that they can function as contextual cues to control attention. In Experiment 1 we associated expressions of anger and happiness with specific proportions of congruent/incongruent flanker trials. We also created consistent and inconsistent category members within each of these two general contexts. The results demonstrated that participants exhibited a larger congruency effect when presented with faces in the emotional group associated with a high proportion of congruent trials. Notably, this effect transferred to inconsistent members of the group. In Experiment 2 we replicated the effects with faces depicting true and false smiles. Together these findings provide consistent evidence that individuals spontaneously utilise emotions to categorise others and that such categories determine the allocation of attentional control.

The effect of a live Mycoplasma gallisepticum vaccine on the horizontal transmission of this Mycoplasma species was quantified in an experimental animal transmission model in specific pathogen free White Layers. Two identical trials were performed, each consisting of two experimental groups and one control group. The experimental groups each consisted of 20 birds 21 weeks of age, which were housed following a pair-wise design. One group was vaccinated twice with a commercially available live attenuated M. gallisepticum vaccine, while the other group was not vaccinated. Each pair of the experimental group consisted of a challenged chicken (10(4) colony-forming units intratracheally) and a susceptible in-contact bird. The control group consisted of 10 twice-vaccinated birds housed in pairs and five individually housed non-vaccinated birds. The infection was monitored by serology, culture and quantitative polymerase chain reaction. The vaccine strain and the challenge strain were distinguished by a specific polymerase chain reaction and by random amplified polymorphic DNA analysis. In both experiments, all non-vaccinated challenged chickens and their in-contact 'partners' became infected with M. gallisepticum. In the vaccinated challenged and corresponding in-contact birds, a total of 19 and 13 chickens, respectively, became infected with M. gallisepticum. Analysis of the M. gallisepticum shedding patterns showed a significant effect of vaccination on the shedding levels of the vaccinated in-contact chickens. Moreover, the Cox Proportional Hazard analysis indicated that the rate of M. gallisepticum transmission from challenged to in-contact birds in the vaccinated group was 0.356 times that of the non-vaccinated group. In addition, the overall estimate of R (the average number of secondary cases infected by one typical infectious case) of the vaccinated group (R = 4.3, 95% confidence interval = 1.6 to 49.9) was significantly lower than that of the non-vaccinated group (R = infinity, 95% confidence interval = 9.9 to infinity). However, the overall estimate of R in the vaccinated group still exceeded 1, which indicates that the effect of the vaccination on the horizontal transmission M. gallisepticum is insufficient to stop its spread under these experimental conditions.

Subject descriptions, control groups, and research designs in published studies of language-impaired children.

We reviewed the 1983-1988 issues of six journals that frequently publish papers including specifically language-impaired (LI) subjects. A total of 92 research reports provided data for our review. The research reports included experimental studies, ex post facto studies, and intervention studies. These studies represent a broad spectrum of the theoretical and empirical foundations of knowledge regarding LI children. The analysis of the published research centered on subject descriptions and the use of control groups. A descriptive analysis of the data showed few consistent trends among the studies with respect to subject selection, subject description, and the number and types of control groups. We discuss the importance of more complete subject descriptions in studies of LI children as well as the importance of the choice of matching criteria for control groups in between-subjects designs.

To evaluate the theory of mind in autism spectrum disorders (ASD) and control individuals by applying the Strange Stories test that was translated and adapted to the Portuguese language. Twenty-eight children with ASD and 56 controls who were all male and aged between 6 and 12 years participated in the study. There were significant differences between the median scores of the groups for each of the 12 stories of the test and for the sum total of all the median scores. The median scores for all stories were significantly greater in the control group than those in the experimental group (children with ASD). In addition, the protocol had excellent internal consistency. The theory of mind skills assessed with the Strange Stories test indicated alterations in children with ASD compared with children in the control group.

The aim of this study was to investigate of oxidant/antioxidant balance in dogs with sarcoptic mange. The study materials consisted of totally 30 cross-breed male dogs; 15 with sarcoptic mange (study group) and 15 healthy as control. Blood samples for analyses were taken from control and study group. In study group, microscopic examination of dermal scrapings of 15 dogs revealed S. scabies. Lipid hydroperoxide level, total oxidant status and oxidative stress index in dogs with sarcoptic mange were higher (P<0.01, P<0.01 and P<0.05, respectively) than the control. Otherwise; sulphydril levels in dogs with sarcoptic mange were lower (P<0.05) than that of control. No significant differences were observed in total antioxidant capacity between groups. Our results suggest a possible relationship between oxidant/antioxidant imbalance and sarcoptic mange infestation in dogs.

A randomized controlled trial to investigate the impact of a low glycemic index (GI) diet on body mass index in obese adolescents

Background The role of a low glycemic index (GI) diet in the management of adolescent obesity remains controversial. In this study, we aim to evaluate the impact of low GI diet versus a conventional Chinese diet on the body mass index (BMI) and other obesity indices of obese adolescents. Methods Obese adolescents aged 15–18 years were identified from population-recruited, territory-wide surveys. Obesity was defined as BMI ≥95th percentile of Hong Kong local age- and sex-specific references. Eligible subjects were randomized to either an intervention with low GI diet (consisting of 45-50% carbohydrate, 30-35% fat and 15-20% protein) or conventional Chinese diet as control (consisting of 55-60% carbohydrate, 25-30% fat and 10-15% protein). We used random intercept mixed effects model to compare the differential changes across the time points from baseline to month 6 between the 2 groups. Results 104 obese adolescents were recruited (52 in low GI group and 52 in control group; 43.3% boys). Mean age was 16.7 ± 1.0 years and 16.8 ±1.0 years in low GI and control group respectively. 58.7% subjects completed the study at 6 months (65.4% in low GI group and 51.9% in control group). After adjustment for age and sex, subjects in the low GI group had a significantly greater reduction in obesity indices including BMI, body weight and waist circumference (WC) compared to subjects in the control group (all p <0.05). After further adjustment for physical activity levels, WC was found to be significantly lower in the low GI group compared to the conventional group (p = 0.018). Conclusion Low GI diet in the context of a comprehensive lifestyle modification program may be an alternative to conventional diet in the management of obese adolescents.

Recent studies aimed to evaluate the potential effects of perceptive rehabilitation in Parkinson Disease reporting promising preliminary results for postural balance and pain symptoms. To date, no randomized controlled trial was carried out to compare the effects of perceptive rehabilitation and conventional treatment in patients with Parkinson Disease. To evaluate whether a perceptive rehabilitation treatment could be more effective than a conventional physical therapy program in improving postural control and gait pattern in patients with Parkinson Disease. Single blind, randomized controlled trial. Department of Physical and Rehabilitation Medicine of a University Hospital. Twenty outpatients affected by idiopathic Parkinson Disease at Hoehn and Yahr stage ≤3. Recruited patients were divided into two groups: the first one underwent individual treatment with Surfaces for Perceptive Rehabilitation (Su-Per), consisting of rigid wood surfaces supporting deformable latex cones of various dimensions, and the second one received conventional group physical therapy treatment. Each patient underwent a training program consisting of ten, 45-minute sessions, three days a week for 4 consecutive weeks. Each subject was evaluated before treatment, immediately after treatment and at one month of follow-up, by an optoelectronic stereophotogrammetric system for gait and posture analysis, and by a computerized platform for stabilometric assessment. Kyphosis angle decreased after ten sessions of perceptive rehabilitation, thus showing a substantial difference with respect to the control group. No significant differences were found as for gait parameters (cadence, gait speed and stride length) within Su-Per group and between groups. Parameters of static and dynamic evaluation on stabilometric platform failed to demonstrate any statistically relevant difference both within-groups and between-groups. Perceptive training may help patients affected by Parkinson Disease into restoring a correct midline perception and, in turn, to improve postural control. Perceptive surfaces represent an alternative to conventional rehabilitation of postural disorders in Parkinson Disease. Further studies are needed to determine if the association of perceptive treatment and active motor training would be useful in improving also gait dexterity.

Tutoring in suturing was developed to compensate for a shortage of suturing cases. The objective of this study was to compare ideal suturing score (ISS; 9 points), suturing time (min:sec), and suture placement error (mm) between medical students completing the suturing tutoring program and medical students attending ordinary medical school training program. Participants consisted of 2 groups of medical students who had never performed suturing. The study group had the role of suturing tutor to teach interested high school students. The control group consisted of volunteers from the ordinary medical school program. Skills measurement was performed by having students from both the groups perform 3 vertical mattress sutures on a model. The study group was tested at weeks 1, 9, and 10 to assess improvement. Both the groups were tested at week 10 to compare final learning outcome. There were 41 and 40 participants in the study group and the control group, respectively. ISS was significantly improved in the study group from week 1-week 10 (7.0 ± 1.3 vs. 8.2 ± 0.9, p = 0.01). At week 10, the study group had a higher mean ISS than the control group (8.2 ± 0.9 vs. 7.8 ± 1.1, p = 0.68). Mean suturing time and mean placement error were also lower in the study group at the end of suturing training (5:1 ± 1:0 vs. 5:2 ± 1:2, p = 0.13; 7.4 ± 7.4 vs. 8.0 ± 10.8, p = 0.44). Tutoring trainees to suture can improve a student's ability to learn how to suture. Copyright © 2016 Association of Program Directors in Surgery. Published by Elsevier Inc. All rights reserved.

Although hyperseborrhea, follicular hyperkeratinization, Propionibacterium acnes colonization and inflammation are found to be responsible in the pathogenesis of acne, the exact mechanisms are unknown. Vitamin A and E are basic antioxidants vital for health. Zinc is also an essential element for human. But these parameters of the effects on skin are not fully understood. We aimed to evaluate plasma levels of vitamin A, E and zinc in acne patients in relation to the severity of the disease. There were 94 acne patients who were referred to our clinic, all new diagnosed, and 56 age and sex matched healthy volunteers as control group. All patients are assessed according to Global Acne Grading System and grouped as mild, moderate, severe and very severe. Acne patients further grouped as group 1 consist of patients with mild to moderate disease; and group 2 consist of patients with severe to very severe acne. The patients with the controls and group 1 with group 2 was compared. The level of vitamin E, vitamin A and zinc were significantly lower than the control group (Table 1,p < 0.001). When the patient group is compared among each other there was no statistically significant difference for plasma vitamin A levels between group 1 and 2 whereas vitamin E and zinc levels were significantly low in group 2 than group 1. Thus there was a negative correlation between acne severity and vitamin E and zinc levels. Our study marks the importance of diet in patients with acne. We offer supportive dietary measures with foods rich in vitamin A and E and zinc in the acne prophylaxis and treatment. Supportive treatment with these vitamins and zinc in severe acne may lead to satisfactory results.

The Lifestyle Improvement through Food and Exercise (LIFE) study is a community-based randomized-controlled trial to measure the effectiveness of a lifestyle intervention to improve glycemic control among African Americans with type 2 diabetes attending safety net clinics. The study enrolled African American adults with a diagnosis of type 2 diabetes and HbA1c ≥ 7.0 who had attended specific safety net community clinics in the prior year. 210 patients will be enrolled and randomized to either the LIFE intervention or a standard of care control group, which consists of two dietitian-led diabetes self-management classes. The LIFE intervention was delivered in 28 group sessions over 12 months and focused on improving diet through dietitian-led culturally-tailored nutrition education, increasing physical activity through self-monitoring using an accelerometer, increasing ability to manage blood sugar through modifications to lifestyle, and providing social support for behavior change. In addition to the group sessions, peer supporters made regular telephone calls to participants to monitor progress toward behavioral goals and provide social support. The 12-month intervention phase was followed by a six-month maintenance phase consisting of two group sessions. The primary outcome of the study is change in A1C from baseline to 12 months, and an additional follow-up will occur at 18 months. The hypothesis of the study is that the participants in the LIFE intervention will show a greater improvement in glycemic control over 12 months than participants in the control group.

The objective of the study was to perform a clinical, comparative assessment of the degree of postural deformities before and after the treatment of idiopathic scoliosis in patients treated with SpineCor brace compared to the control group. A group of 90 children with idiopathic scoliosis (including 74 girls) at the average age of 12.2 was subject to prospective observation. Average pre-treatment Cobb angle was 24.9° in the thoracic spine and 25.8° in the lumbar spine. The group actively treated with the SpineCor brace consisted of 45 children, while the control group consisted of the remaining 45 children with the natural course of the disease. Both groups did not differ significantly in terms of age, gender, height, body weight, Risser sign of skeletal maturity and baseline clinical and radiological parameters of scoliosis. Significant reduction of rib hump was observed upon 2-year SpineCor brace treatment (P=0.04) compared to the group treated by physiotherapy only (P=0.91). Similarly, improvement in lumbar prominence was observed in the actively treated group (P=0.009), with a trend towards worse results in the control group (P=0.07) In the group treated with the SpineCor brace, significant reduction in pectoral and hamstring muscle contractures as well as reduction in shoulder asymmetry and reduction in anterior and posterior vertical deviation were observed. Treatment using the SpineCor dynamic brace leads to a clinical improvement in posture, particularly to reduction in rib hump, lumbar prominence and muscular contractures.

The purpose of our study was to assess soft tissue features of acute patellar tendon rupture on lateral knee radiograph that would facilitate early diagnosis. The participants were divided into two groups of 35 patients each. There were 28 men and seven women with a mean age of 46 years in the control group and 26 men and nine women with a mean age of 47 years in the rupture group. The lateral knee radiograph of each patient was evaluated for Insall-Salvati ratio for patella alta, increased density of the infrapatellar fat pad, appearance of the soft tissue margin of the patellar tendon and bony avulsions. In the rupture group there were three consistent soft tissue radiographic features in addition to patellar alta. These were increased density of infrapatellar fat pad; loss of sharp, well-defined linear margins of the patellar tendon and angulated wavy margin of the patellar tendon while in the control group these features were not observed. The soft tissue radiographic features described in the rupture group are consistent and reliable. When coupled with careful clinical assessment, these will aid in early diagnosis and further imaging will be seldom required. © 2015 Chinese Orthopaedic Association and Wiley Publishing Asia Pty Ltd.

The subjects' body surface EMF was determined in the prone position before and after the chiropractic adjustment. A Toftness low-force chiropractic adjustment was applied to the cervical, thoracic, lumbar, and sacral areas as determined by the practitioner. Heart rate variability analysis was recorded once a week to determine autonomic nervous system activity in both the control and experimental groups. The EMF on the subjects' body surface decreased after chiropractic adjustment at the cervical, thoracic, lumbar, and sacral regions in all 6 visits during the 4-week treatment period. The EMF showed a downtrend over the 4-week period after the low-force adjustment. The same changes were not observed in the control group. The chiropractic adjustment group had a slight decrease in heart rate over the 4-week treatment period, and no significant change was observed in the control group. Heart rate variability analysis did not show consistent changes before and after the low-force adjustments during the treatment period. Low-force chiropractic adjustment in the cervical and thoracic areas resulted in a consistent reduction of the body surface EMF after 4 weeks of active treatment. No statistically significant differences were found in the heart rate and heart rate variability in the 4-week study.

To examine the effects of high-fidelity patient simulation (HFPS) led clinical reasoning course among undergraduate nursing students. A quasi-experimental study of non-equivalent control group pretest-post test design was applied. A total of 49 senior nursing students participated in this study. The experimental group consisted of the students who took the "clinical reasoning" course (n = 23) while the control group consisted of students who did not (n = 26). Self-administered scales including the nursing core competencies, problem solving, academic self-efficacy, and Kolb learning style inventory were analyzed quantitatively using SPSS version 20.0. Data analysis was conducted using one-way ancova due to a significant difference in nursing core competencies between the experimental group and control group. There was a significant improvement in nursing core competencies in the experimental group (F = 7.747, P = 0.008). The scores of problem solving and academic self-efficacy were higher in the experimental group after the HFPS led clinical reasoning course without statistical difference. There is a need for the development of effective instructional methods to improve learning outcomes in nursing education. Future research is needed related to simulation education as well as management strategies so that learning outcomes can be achieved within different students' learning style. © 2015 The Authors.

The present investigation examined intrinsic and extrinsic reasons for quitting among daily cigarette smokers with posttraumatic stress disorder (PTSD) as compared to clinical daily smokers with other anxiety and mood disorders (AM) and daily smokers with no current axis I psychopathology (C) prior to a self-guided quit attempt. It was hypothesized that (1) the PTSD group would report greater intrinsic (i.e., self-control and health concerns) reasons for quitting smoking, and (2) among those with PTSD, anxiety sensitivity (fear of anxiety; AS) would predict greater intrinsic reasons for quitting smoking. Participants were 143 (58.7% female; Mage = 29.66 years, SD = 11.88) daily cigarette smokers. Partially consistent with prediction, the PTSD group reported significantly greater self-control intrinsic reasons for quitting, but not health concern intrinsic reasons, than the C group (p <.01). The PTSD group also reported greater immediate reinforcement extrinsic reasons for quitting than the C group (p <.05). The PTSD and AM groups did not significantly differ on any reasons for quitting. Also partially consistent with hypotheses, higher levels of anxiety sensitivity in daily smokers with axis I psychopathology (both PTSD and AM groups) significantly predicted greater self-control intrinsic reasons for quitting. AS did not significantly predict immediate reinforcement extrinsic reasons for quitting. The current findings suggest that individuals with PTSD and other psychopathology may have unique motivations for quitting smoking that could be usefully explored within smoking cessation treatment programs.

Early cochlear implantation aids auditory feedback and supports better communication and self-monitoring of the voice. The objective of this study was to determine whether the age of cochlear implantation has an impact on vocal development in children implanted before age 4. The study consisted of 19 participants in total. All implant recipients (experimental group) were 3-5 years post-implantation, including four prelingual (0-2 years) and five perilingual (2-4 years) implant recipients. The control group consisted of 10 children whose hearing was within normal limits between the ages 3-6 years and 10 months, which was compared to the experimental group. Established paediatric norms were used for additional comparison. A questionnaire was used to gather information from each of the participant's caregivers to determine whether other personal and contextual factors had an impact on voice production. An acoustic analysis was conducted for each participant using the Multi-Dimensional Voice Program of the Computerized Speech Lab. When the experimental group and the control group were compared, similar results were yielded for fundamental frequency and short-term perturbation (jitter and shimmer). More variability was noted in long-term frequency and amplitude measures, with significantly higher differences, and therefore further outside the norms, in the prelingual group when compared to the perilingual and control groups. In this study, age of implantation did not impact vocal characteristics. Further research should include larger sample sizes, with participants that are age and gender matched.

Asthma is a common systemic disease occurring in infancy and adolescence, time periods that could encompass orthodontic treatment. Asthma is an inflammatory disease; therefore, it might interfere with orthodontic tooth movement. The purpose of the study was to analyze the histomorphologic aspects of the periodontal ligament of asthmatic Wistar rats in the initial period of orthodontic movement. Thirty-two Wistar rats were divided into 4 groups: 2 control groups consisting of rats without induced allergic asthma, and 2 experimental groups consisting of rats with induced allergic asthma. The animals of the first control and experimental groups did not receive orthodontic forces, whereas those in the second control and experimental groups were subjected to mesial movement of the maxillary left first molar for 3 days. The samples were prepared for histomorphometric analysis of the periodontal ligament. The area of the periodontal ligament was calculated as a function of root length in the cervical and apical regions of the distal face of the maxillary first molar mesial root. The Student t test and the Welch correlation test were applied to the data obtained. There was a statistically significant difference (P <0.05) between the control and experimental groups. An enhanced response to orthodontic force was observed in the asthmatic animals: the periodontal ligament was more compressed at the pressure area and more stretched in the traction area. Our findings indicate that experimental allergic asthma seems to exacerbate orthodontic movement in rats. Copyright © 2012 American Association of Orthodontists. Published by Mosby, Inc.

1. The effects of ascorbic acid (L-ascorbic acid) and melatonin supplementation on performance, carcase characteristics, malondialdehyde (MDA) as lipid peroxidation indicator, ascorbic acid, retinol, tocopherol and mineral status in the Japanese quail (Coturnix coturnix japonica) exposed to high ambient temperature were evaluated. 2. Two hundred and forty Japanese quails (10 d old) were randomly assigned to 8 treatment groups consisting of 10 replicates of three birds each. The birds were kept in a temperature-controlled room at 22 degrees C (Thermoneutral, TN groups) or 34 degrees C (for 8 h/d; 09:00 to 17:00 h; Heat stress, HS groups). Birds in both TN and HS were fed either a basal (control) diet or the basal diet supplemented with 250 mg of L-ascorbic acid/kg of diet (Ascorbic acid group), 40 mg of melatonin/kg of diet (Melatonin group) or both (Ascorbic acid + Melatonin group). 3. Supplementing heat-stressed quails with ascorbic acid and melatonin improved performance compared with the control group. Effects generally were greatest in quails supplemented with both ascorbic acid and melatonin. 4. Although supplementation did not consistently restore the concentrations of serum ascorbic acid, retinol and tocopherol to those of TN groups, these concentrations increased significantly with supplementation. Furthermore, serum and liver MDA and serum cholesterol and glucose concentrations were lower in the supplemented groups than in the heat-stressed controls. 5. Within each environment, excretion of Ca, P, Mg, Zn, Fe and Cr were lowest in the combination group and, in all cases, highest in the HS group. Interactions between diet and temperature were detected for live weight gain, cold carcase weight, MDA, ascorbic acid, tocopherol concentrations and excretion of zinc. 6. The results of the study indicate that ascorbic acid and melatonin supplementation attenuate the decline in performance and antioxidant and mineral status caused by heat stress and such supplementation may offer protection against heat-stress-related depression in performance of Japanese quails.

Comparing live to recorded speech in training the perception of spectrally shifted noise-vocoded speech.

PubMed

Faulkner, Andrew; Rosen, Stuart; Green, Tim

2012-10-01

Two experimental groups were trained for 2 h with live or recorded speech that was noise-vocoded and spectrally shifted and was from the same text and talker. These two groups showed equivalent improvements in performance for vocoded and shifted sentences, and the group trained with recorded speech showed consistently greater improvements than untrained controls. Another group trained with unshifted noise-vocoded speech improved no more than untrained controls. Computer-based training thus appears at least as effective as labor-intensive live-voice training for improving the perception of spectrally shifted noise-vocoded speech, and by implication, for training of users of cochlear implants.

1994-05-01

Two groups of 16 subjects, 8 of each gender, were examined on two occasions, one group before and after restricted environmental stimulation with floatation, and the other group without floatation was the control group. They were examined with a tactile object discrimination task carried out with each hand separately while blindfolded, and with a recognition memory test for words and unfamiliar faces, a test validated on neurological patients with left and right hemispheric lesions respectively. Consistent with both tasks the floatation group showed a significantly greater enhancement of right hemispheric processing after floatation than was found when retesting the controls. The results were distinguished from previous research on hypnosis where the same relative state of hemispheric imbalance was achieved with the same tasks, but largely through inhibitory influences on the left hemisphere.

The Sensory Perception Quotient (SPQ): development and validation of a new sensory questionnaire for adults with and without autism.

Questionnaire-based studies suggest atypical sensory perception in over 90% of individuals with autism spectrum conditions (ASC). Sensory questionnaire-based studies in ASC mainly record parental reports of their child's sensory experience; less is known about sensory reactivity in adults with ASC. Given the DSM-5 criteria for ASC now include sensory reactivity, there is a need for an adult questionnaire investigating basic sensory functioning. We aimed to develop and validate the Sensory Perception Quotient (SPQ), which assesses basic sensory hyper- and hyposensitivity across all five modalities. A total of 359 adults with (n = 196) and without (n = 163) ASC were asked to fill in the SPQ, the Sensory Over-Responsivity Inventory (SensOR) and the Autism-Spectrum Quotient (AQ) online. Adults with ASC reported more sensory hypersensitivity on the SPQ compared to controls (P < .001). SPQ scores were correlated with AQ scores both across groups (r = .-38) and within the ASC (r = -.18) and control groups (r = -.15). Principal component analyses conducted separately in both groups indicated that one factor comprising 35 items consistently assesses sensory hypersensitivity. The SPQ showed high internal consistency for both the total SPQ (Cronbach's alpha = .92) and the reduced 35-item version (alpha = .93). The SPQ was significantly correlated with the SensOR across groups (r = -.46) and within the ASC (r = -.49) and control group (r = -.21). The SPQ shows good internal consistency and concurrent validity and differentiates between adults with and without ASC. Adults with ASC report more sensitivity to sensory stimuli on the SPQ. Finally, greater sensory sensitivity is associated with more autistic traits. The SPQ provides a new tool to measure individual differences on this dimension.

It is not clear whether patient's psycho-education enhances compliance to antipsychotic treatments and reduces the number of relapses. Here we investigated the impact of a new psycho-educational program (SOLEDUC) on the one- and two-years rate of relapse (primary outcome measure) and a number of clinical assessments (secondary outcome measures). This was a multicentric French clinical trial (51 centers) of Phase IV, open, controlled, randomized, consisting in two parallel groups: the Soleduc group (N=111) and the control group (N=109). All subjects received a variable dose over the 2-year period of the same antipsychotic drug (amisulpride). Soleduc consisted of a 7-session program (1h per session), presented three times (at baseline, 6-months and 12-months). Patients in the control group received a non-specific psychosocial training for an equivalent period of time. The models of Andersen-Gill (AG) and Prentice, Williams and Peterson (PWP) were used to analyze relapses. Patients in the Soleduc group attended 14.8+/-6.1 sessions (mean+/-SD), including 17 patients who never attended a session. Intent to treat analysis showed less patients relapsing in the Soleduc group as compared to the control group (21.6% versus 28.4% after 1 year and 84.4% versus 90.8% after 2years), but the differences were not statistically significant. Relapse risk was significantly reduced for patients who followed at least 7 modules (p=0.015 AG-test; p<0.001 PWP-test). In conclusion, no significant differences in relapse rates were found between patients attending the Soleduc program and the control group. Attendance of at least 7 out of 21 program sessions was required to see a modest, but significant two-year relapse prevention in schizophrenia. Other well designed studies are required to evaluate the medical impact of patient's education programs.

The aim of this study was to lace dental glass fibre reinforced composite (FRC) prepreg with chlorhexidine digluconate and to examine the adherence of common oral fungal pathogen Candida albicans to FRC made of the prepreg. Four different test and control material groups each comprising 16 test specimens ((5.0 x 5.0 x 0.8) mm3) each were used as substrates for C. albicans adherence. A porous polymer pre-impregnated woven glass fibre prepreg was laced with solution of chlorhexidine gluconate and it was used with autopolymerized denture base polymer to fabricate FRC test specimens. Control group (Group 1) consisted of FRC test specimens stored in water. In Group 2, the test specimens were stored in 10% chlorhexidine digluconate solution for 24 h. Group 3 consisted of specimens fabricated using such fibre reinforcements which were pre-soaked in 20% chlorhexidine digluconate and dried before preparation with denture base resin, and followed by storage of the specimens in water. Group 4 was similar to Group 3 but instead of water storage the specimens were immersed in 10% chlorhexidine digluconate for 24 h. For the candidal adhesion assay the test and control specimens were incubated in standardized suspensions of four different strains of C. albicans, rinsed and prepared for light-microscopy. The mean number of adherent cells in each group was counted microscopically and analysed statistically. There were significantly (P < 0.05) more adherent C. albicans cells found in Group 1 than in the other three groups which did not differ significantly from each other. The lowest numbers of adherent cells were found in Group 3. Pretreating the porous polymer pre-impregnated glass fibre reinforcement with chlorhexidine digluconate result in reduction in the number of adherent yeast cells on the surface FRC material.

A cardiac catheterization laboratory can be a frightening environment and music can be a supportive source of environmental sound that stimulates and maintains relaxation. However, the results of studies are conflicting in this regard. The aim of this study was to investigate the effect of music therapy on patients' anxiety and hemodynamic parameters during percutaneous transluminal coronary angioplasty. This was a randomized controlled trial, conducted in the Catheterization Laboratory Unit of Baqiyatallah Hospital, in Tehran, Iran. A sample of 64 patients, who were planned to undergo coronary angioplasty, was recruited. Patients were randomly allocated to either the control or the experimental groups. In the experimental group, patients received a 20 to 40-minute music therapy intervention, consisting of light instrumental music albums by Johann Sebastian Bach and Mariko Makino. Patients in the control group received the routine care of the study setting, which consisted of no music therapy intervention. Study data were collected by a demographic questionnaire, the Spielberger's State Anxiety Inventory, and a data sheet for documenting hemodynamic parameters. Chi-square, independent-samples t tests, paired-samples t-test and repeated measures analysis of variance were used to analyze the data. Before the intervention, the study groups did not differ significantly in terms of anxiety level and hemodynamic parameters. Moreover, the differences between the two groups, regarding hemodynamic parameters, were not significant after the intervention (P > 0.05). However, the level of post-intervention anxiety in the experimental group was significantly lower than the control group (32.06 ± 8.57 and 38.97 ± 12.77, respectively; P = 0.014). Compared with the baseline readings, the level of anxiety in the control group did not change significantly after the study (41.91 ± 9.88 vs. 38.97 ± 12.77; P = 0.101); however, in the experimental group, the level of post-intervention anxiety was significantly lower than the pretest readings (32.06 ± 8.57 vs. 41.16 ± 10.6; P = 0.001). Music therapy is a safe, simple, inexpensive, and non-invasive nursing intervention, which can significantly alleviate patients' anxiety during coronary angioplasty.

Assessment of MMP-9, TIMP-1, and COX-2 in normal tissue and in advanced symptomatic and asymptomatic carotid plaques

PubMed Central

2011-01-01

Background Mature carotid plaques are complex structures, and their histological classification is challenging. The carotid plaques of asymptomatic and symptomatic patients could exhibit identical histological components. Objectives To investigate whether matrix metalloproteinase 9 (MMP-9), tissue inhibitor of MMP (TIMP), and cyclooxygenase-2 (COX-2) have different expression levels in advanced symptomatic carotid plaques, asymptomatic carotid plaques, and normal tissue. Methods Thirty patients admitted for carotid endarterectomy were selected. Each patient was assigned preoperatively to one of two groups: group I consisted of symptomatic patients (n = 16, 12 males, mean age 66.7 ± 6.8 years), and group II consisted of asymptomatic patients (n = 14, 8 males, mean age 67.6 ± 6.81 years). Nine normal carotid arteries were used as control. Tissue specimens were analyzed for fibromuscular, lipid and calcium contents. The expressions of MMP-9, TIMP-1 and COX-2 in each plaque were quantified. Results Fifty-eight percent of all carotid plaques were classified as Type VI according to the American Heart Association Committee on Vascular Lesions. The control carotid arteries all were classified as Type III. The median percentage of fibromuscular tissue was significantly greater in group II compared to group I (p < 0.05). The median percentage of lipid tissue had a tendency to be greater in group I than in group II (p = 0.057). The percentages of calcification were similar among the two groups. MMP-9 protein expression levels were significantly higher in group II and in the control group when compared with group I (p < 0.001). TIMP-1 expression levels were significantly higher in the control group and in group II when compared to group I, with statistical difference between control group and group I (p = 0.010). COX-2 expression levels did not differ among groups. There was no statistical correlation between MMP-9, COX-2, and TIMP-1 levels and fibrous tissue. Conclusions MMP-9 and TIMP-1 are present in all stages of atherosclerotic plaque progression, from normal tissue to advanced lesions. When sections of a plaque are analyzed without preselection, MMP-9 concentration is higher in normal tissues and asymptomatic surgical specimens than in symptomatic specimens, and TIMP-1 concentration is higher in normal tissue than in symptomatic specimens.

Mindfulness training modifies subsystems of attention.

PubMed

Jha, Amism P; Krompinger, Jason; Baime, Michael J

2007-06-01

Mindfulness is defined as paying attention in the present moment. We investigate the hypothesis that mindfulness training may alter or enhance specific aspects of attention. We examined three functionally and neuroanatomically distinct but overlapping attentional subsystems: alerting, orienting, and conflict monitoring. Functioning of each subsystem was indexed by performance on the Attention Network Test. Two types of mindfulness training (MT) programs were examined, and behavioral testing was conducted on participants before (Time 1) and after (Time 2) training. One training group consisted of individuals naive to mindfulness techniques who participated in an 8-week mindfulness-based stress reduction (MBSR) course that emphasized the development of concentrative meditation skills. The other training group consisted of individuals experienced in concentrative meditation techniques who participated in a 1-month intensive mindfulness retreat. Performance of these groups was compared with that of control participants who were meditation naive and received no MT. At Time 1, the participants in the retreat group demonstrated improved conflict monitoring performance relative to those in the MBSR and control groups. At Time 2, the participants in the MBSR course demonstrated significantly improved orienting in comparison with the control and retreat participants. In contrast, the participants in the retreat group demonstrated altered performance on the alerting component, with improvements in exogenous stimulus detection in comparison with the control and MBSR participants. The groups did not differ in conflict monitoring performance at Time 2. These results suggest that mindfulness training may improve attention-related behavioral responses by enhancing functioning of specific subcomponents of attention. Whereas participation in the MBSR course improved the ability to endogenously orient attention, retreat participation appeared to allow for the development and emergence of receptive attentional skills, which improved exogenous alerting-related process.

Dental implant insertion for oral rehabilitation is a worldwide procedure for healthy and medically compromised patients. The impact of systemic disease risks on the outcome of implant therapy is unclear, since there are few if any published randomized controlled trials (RCTs). The objective of this study is to investigate the rate of complications and failures following dental implantation in medically compromised patients in order to elucidate risk factors and prevent them. A retrospective cohort study was conducted from patient files treated with dental implantation between the years 2008-2014. The study group consisted of medically complex patients while the control group consisted of healthy patients. Preoperative, intraoperative, and post operative clinical details were retrieved from patients' files. The survival rate and the success rate of the dental implants were evaluated clinically and radiographically. A total of 204 patients (1003 dental implants) were included in the research, in the study group, 93 patients with 528 dental implants and in the control group, 111 patients with 475 dental implants. No significant differences were found between the groups regarding implant failures or complications. The failure rate of dental implants among the patients was 11.8 % in the study group and 16.2 % in the control group (P = 0.04). It was found that patients with a higher number of implants (mean 6.8) had failures compared with patients with a lower number of implants (mean 4.2) regardless of their health status (P < 0.01). We found a similar rate of failure and complications of dental implantation in medically complex patients and in healthy patients. Medically complex patients can undergo dental implantation. There are similar rates of complications and failures of dental implants in medically complex patients and in healthy patients.

[Adaptation of the Hinting Task theory of the mind test to Spanish].

2012-01-01

Many studies have found that patients with schizophrenia have a deficit in theory of mind. Some authors associate this deficit with the presence of symptoms, while others maintain that it can also be observed in patients in the remission phase. There is no reference test to assess theory of mind in schizophrenia, although one of the most used is the Hinting Task. The aim of the present study consists of adapting and validating, in Spanish, the 10 histories that make up this test. The study was conducted on a sample of 39 control subjects and 40 patients with schizophrenia. The internal consistency and the between-observer reliability and test-retest were assessed in both sample groups. The performance of the patients and control subjects were also compared. Good reliability data was obtained in the inter-observer and test-retest in the two samples. On the other hand, the internal consistency was somewhat low for all of the 10 histories. For this reason, and starting from a previous study, a reduced version of 5 histories was prepared, which showed good internal consistency. The patients with schizophrenia obtained a significantly lower score than the control subjects in 8 out of the 10 histories. The reduced Spanish version of the Hinting Task demonstrated good psychometric properties. When compared to the control group, the patients with schizophrenia had a deficit in theory of mind.

Central serous chorioretinopathy (CSCR) is a poorly understood disease and the choroidal circulation abnormality induced by the plasminogen activator inhibitor type 1 (PAI-1) seems to be associated with the pathogenesis. There are many reports indicating that 4 G/5 G polymorphism of the PAI-1 gene is a risk factor for several diseases related to the elevated serum levels of PAI-1. To evaluate the 4 G/5 G polymorphism of the PAI-1 gene and its association with serum levels of PAI-1 in acute CSCR patients. Sixty CSCR patients and 50 healthy control patients were included. The PAI-1 4 G/5 G was genotyped using the polymerase chain reaction-restriction technique. Serum PAI-1 level was measured using enzyme-linked immunosorbent assay. Demographic data consisting of age, sex, body mass index (BMI) as well as genotype disturbances and serum PAI-1 levels were compared between the groups. Statistical significance for differences in the serum PAI-1 levels of each group with different genotypes was also analyzed. The CSCR group consisted of 40 male (66.7%) and 20 female (33.3%) patients with a mean age of 46.7 ± 8.39 years. The control group consisted of 32 male (64%) and 18 female (36%) healthy subjects with a mean age of 45.8 ± 8.39 years. There was no statistically significant difference between the groups in terms of age, sex and BMI. In the CSCR group the genotype frequencies were 4 G/4G: 30% (n = 18), 4G/5 G: 50% (n = 30), 5 G/5G: 20% (n = 12) and in the control group genotype frequencies were 34% (n = 17), 42% (n = 21) and 24% (n = 12), respectively. There was no statistically significant difference in the distribution of genotypes among the groups (chi-squared, p = 0.70). The CSCR group had a significantly higher serum PAI-1 concentration than the control group (p = 0.001). In both groups the mean plasma PAI-1 concentration did not vary significantly among the different genotypes (p > 0.05). Although our results demonstrated that the patients with acute CSCR have higher serum PAI-1 concentrations than the controls, no significant difference was found in the genotype disturbances of the PAI-1 gene between the groups. The current study indicates that 4 G/5 G polymorphism in the promoter of the PAI-1 gene cannot be considered a risk factor for the elevated serum PAI-1 levels and consequent development of CSCR.

A major cause of skin aging is a chronic micro-inflammation triggered by UV radiation and external pollutants. It has been demonstrated that blue light diminishes inflammatory conditions and near infrared light enhances circulation. To assess the effectiveness of a non thermal dual wavelength -- blue (405 - 420 nm) and near infrared (850 - 900 nm) -- light source in skin rejuvenation, in the reduction of the duration of post skin resurfacing erythema and in the acceleration of healing of post surgical conditions (face lift and breast augmentation). We have utilized a non contact, hand free dual wavelength light source (iClearXL and Clear100XL, Curelight Ltd) to treat over 60 patients and perform three controlled studies in four centers. Follow up duration was three months. Control group for photo-rejuvenation consisted of patients treated with Glycolic peeling and daily appliance of vitamin C Control group for post skin resurfacing erythema duration consisted of patients untreated by the light source and control group for post surgical healing consisted of patients untreated by the light source or treated by the light source on one side only. Post skin resurfacing erythema duration is reduced by 90%. The healing of post surgical conditions is substantially accelerated and discomfort is reduced. The anti aging effect of the light source includes: reduction of pore size in 90% of patients with stable results at three months follow up, enhanced skin radiance in 90% of patients with stable results at three months follow up and smoothing of fine wrinkles in 45% of patients with stable results at three months follow up. The control group showed poor results which were stable for a duration of less than one month. A non thermal, non contact / hand free light source emitting at 405-420 nm and 850-900 nm considerably enhances aesthetic and surgical aesthetic procedures without consuming user time.

Betapol consists of triglyceride fatty acids commonly found in vegetable and animal fats. A similarity to human milk fat indicated a potential use in infant formulae as well as for food use in general. To test the potential for substantial equivalence with a related food grade oil, palm oil, Betapol was fed to rats at 15% content in the diet using an augmented two-generation study, in order to obtain information on general (6 months), reproductive and postnatal developmental toxicity in a single study rather than separate studies. For comparison there were two control groups, namely a comparative control fed a diet containing 15% of food grade oil and a negative, or laboratory standard control fed a commercial rodent breeding diet (LAD), containing 2.3-4.7% fat. It was reasoned that if Betapol fed groups showed differences from the comparative control in the direction of the negative control these would reflect differences in the nutritional value of the high fat diets. Presence of a toxicant might be indicated by differences from the comparative control group opposite to the negative control group. The group fed 15% Betapol showed occasional, statistically significant differences from the comparative control group but the direction of difference was towards the negative control group and did not indicate the presence of an unexpected toxicant.

Women undergoing surgery for ovarian cancer are severely ill and are high users of health services. Contributing to these increased utilization rates are the multiple modalities used to treat ovarian cancer and the complications and side effects from those treatments. The purpose of this study was to evaluate the effectiveness of an intervention provided by advanced practice nurses and a psychiatric consultation-liaison nurse on patients' self-report of healthcare utilization compared with an attention control intervention in women undergoing surgery for a suspected diagnosis of ovarian cancer. A two-group, experimental, longitudinal design was used to compare women who were assigned randomly to the intervention group or to an attention control group at baseline within 48 hours after surgery and 1, 3, and 6 months after surgery. Healthcare utilization was measured as the number of self-reported inpatient admissions and outpatient visits, including emergency room visits, oncology outpatient visits, and primary care visits. Nurse interventions consisted of 16 contacts: symptom management, counseling, education, direct nursing care, coordination of resources, and referrals. The attention control interventions consisted of nine contacts that included instructions on use of a symptom management toolkit and strategies on how to manage symptoms. There were no differences in hospitalizations and oncology outpatient visits between the two groups. The main finding of this study was a significant difference in the number of primary care visits between the two groups. Women in the attention control group went to their primary care providers more often than the intervention group. The women who reported more visits also reported more depressive symptoms. In addition, a trend was found in the number of emergency room visits between the two groups. The intervention group visited the emergency room more often because the nurse instructed patients to go when they recognized symptoms that needed urgent care after hours. Women in the intervention group appropriately used the emergency room to manage their problems after hours, whereas more women in the attention control group reported significantly more primary care visits. These findings highlight the need for healthcare providers representing various disciplines to coordinate services across specialties, especially for women who have depressive symptoms.

Introduction. Bruxism is to press or grind teeth against each other in non-physiologic cases, when an individual does not swallow or chew. If not treated, teeth problems, stress, mental disorders, frequent night waking, and headache is expected. This research aimed to study the effect of hydroxyzine on treating bruxism of 2- to 14-year-old children admitted to the clinic of Bandar Abbas Children Hospital. Methodology. In this clinical trial, 143 children with the ages between 4-12 years were admitted to the Children Hospital and were divided randomly into test and control groups. The test group consisted of 88 hydroxyzine-treated children and the control group consisted of 55 children who used hot towels. Both groups were examined in some stages including the pre-test stages or the stage before starting treatments at two, four, and six weeks and four months after stopping the treatment. The effects of each treatment on reducing bruxism symptoms were assessed by a questionnaire. The data were analyzed by using SPSS in descriptive statistics, t-test, and ANOVA. Results. As far as bruxism severity was concerned, the results showed a significant difference between the test group members who received hydroxyzine and the control group members who received no medication. T-test results showed a statistically significant difference between the test and the control groups in the second post-test (four weeks later) (p. value ≤ 0.05). Mean of the scores of bruxism severity in the test group has changed significantly in the post-test (at two weeks, four weeks, and six weeks later) as compared to the pre-test. Whereas, as far as the response to the treatment, no significant difference was recorded between the control group and the test group 4 weeks after the treatment. Discussion. The results showed that prescribing hydroxyzine for 4 weeks had a considerable effect in diminishing bruxism severity between the test groups. PMID:28316738

Consistency-based rectification of nonrigid registrations

2015-01-01

Abstract. We present a technique to rectify nonrigid registrations by improving their group-wise consistency, which is a widely used unsupervised measure to assess pair-wise registration quality. While pair-wise registration methods cannot guarantee any group-wise consistency, group-wise approaches typically enforce perfect consistency by registering all images to a common reference. However, errors in individual registrations to the reference then propagate, distorting the mean and accumulating in the pair-wise registrations inferred via the reference. Furthermore, the assumption that perfect correspondences exist is not always true, e.g., for interpatient registration. The proposed consistency-based registration rectification (CBRR) method addresses these issues by minimizing the group-wise inconsistency of all pair-wise registrations using a regularized least-squares algorithm. The regularization controls the adherence to the original registration, which is additionally weighted by the local postregistration similarity. This allows CBRR to adaptively improve consistency while locally preserving accurate pair-wise registrations. We show that the resulting registrations are not only more consistent, but also have lower average transformation error when compared to known transformations in simulated data. On clinical data, we show improvements of up to 50% target registration error in breathing motion estimation from four-dimensional MRI and improvements in atlas-based segmentation quality of up to 65% in terms of mean surface distance in three-dimensional (3-D) CT. Such improvement was observed consistently using different registration algorithms, dimensionality (two-dimensional/3-D), and modalities (MRI/CT). PMID:26158083

Chronic renal failure (CRF) is often accompanied by increased oxidative stress and euthyroid sick syndrome (ESS). The cause of ESS is unknown, and it is unknown whether there exists a link between oxidant stress and ESS in CRF patients. Therefore, we aim to investigate oxidative stress and type 1 deiodinase (DIO1) expression, which plays the key role in the ESS in CRF patients. In-patients with CRF were divided into the two group: Group 1 is ESS patients consisting of 60 patients with low free triiodothyronine (FT3) and Group 2 consisting of 60 patients with normal FT3. Group 3 consisted of 60 healthy volunteers recruited as controls. The baseline clinical parameters of patients were evaluated with standard routine methods in a clinical laboratory. Serum levels of 8-isoprostane and DIO1 were measured by enzyme-linked immunosorbent assay (ELISA). Multiple regression analysis was used to analyze the relationship between oxidative stress, DIO1 and FT3. The concentrations of serum 8-Isoprostane in Group 1 and Group 2 were substantially higher than that of Group 3 (p< 0.05), however there was no significant difference between Group 1 and Group 2 (p=0.516). The serum DIO1 level was higher in Group 2 than in Group 1 and Group 3 (p< 0.001). Multivariate linear regression analysis revealed that the DIO1 concentration and FT3 level were not associated with the concentration of serum 8-Isoprostane. CRF patients showed elevated oxidative stress. The CRF patients without ESS showed higher expression of DIO1 than patients with ESS and the control group. The concentration of serum 8-Isoprostane was not correlated with FT3 and DIO1 levels. © 2018 The Author(s). Published by S. Karger AG, Basel.

Total knee arthroplasty (TKA) accompanies the risk of bleeding and need for transfusion. There are several methods to reduce postoperative blood loss and blood transfusion. One such method is using tranexamic acid during TKA. The purpose of this study was to confirm whether tranexamic acid reduces postoperative blood loss and blood transfusion after TKA. A total of 100 TKA patients were included in the study. The tranexamic acid group consisted of 50 patients who received an intravenous injection of tranexamic acid. The control included 50 patients who received a placebo injection. The amounts of drainage, postoperative hemoglobin, and transfusion were compared between the groups. The mean amount of drainage was lower in the tranexamic acid group (580.6±355.0 mL) than the control group (886.0±375.5 mL). There was a reduction in the transfusion rate in the tranexamic acid group (48%) compared with the control group (64%). The hemoglobin level was higher in the tranexamic acid group than in the control group at 24 hours postoperatively. The mean units of transfusion were smaller in the tranexamic acid group (0.76 units) than in the control group (1.28 units). Our data suggest that intravenous injection of tranexamic acid decreases the total blood loss and transfusion after TKA.

Stimulus- and response-reinforcer contingencies in autoshaping, operant, classical, and omission training procedures in rats.

Separate groups of rats received 500 trials of lever-press training under autoshaping (food delivery followed 10-second lever presentations, or occurred immediately following a response); operant conditioning (responding was necessary for food delivery); and classical conditioning (food followed lever presentations regardless of responding). Each group then received 500 trials on an omission procedure in which food was omitted on trials with a response. Another group received 1000 trials on the omission procedure, and a fifth group, random control, received 1000 uncorrelated presentations of lever and food. The autoshaping, operant, and classical groups reached high response levels by the end of initial training. Acquisition was fastest in the autoshaping group. Responding remained consistently low in the control group. The omission group responded at a level between the control group and the other three groups. During omission training, responding in these three groups declined to the omission-group level. During omission training, the rats continued contacting the lever frequently after lever pressing had declined. Response maintenance under omission training seems not to require topographic similarity between the response and reinforcer-elicited consummatory behaviors.

We developed a method that enables differentiation between liquid crystalline-phase particles corresponding to different space groups. It consists of controlled tilting of the specimen to observe different orientations of the same particle using cryogenic transmission electron microscopy. This leads to the visualization of lattice planes (or reflections) that are present for a given structure and absent for the other one(s) and that give information on liquid crystalline structures and their space groups. In particular, we show that we can unambiguously distinguish among particles having the inverted micellar cubic (space group Fd(3)m, 227), the inverted bicontinuous gyroid (space group Ia(3)d, 230), the inverted bicontinuous diamond (space group Pn(3)m, 224), and the inverted bicontinuous primitive cubic structure (space group Im(3)m, 229).

This study aims to identify the effects of relaxation exercises and music therapy on the psychological symptoms and depression levels of patients with chronic schizophrenia. This semi-experimental study was conducted using pre- and post-tests with a control group. The study population consists of patients with schizophrenia who regularly attended community mental health centers in the Malatya and Elazığ provinces of Turkey between May 2015 and September 2015. The study's sample consists of 70 patients with schizophrenia (n=35 in the control group; n=35 in the experimental group) who were selected randomly based on power analysis. The "Patient Information Form," the "Brief Psychiatric Rating Scale (BPRS)" and the "Calgary Depression Scale for Schizophrenia (CDSS)" were used for data collection. Patients in the experimental group participated in relaxation exercises and music therapy 5 times a week for 4 weeks. The experimental group of 35 persons was divided into three groups of approximately 10-12 individuals in order to enable all participants to attend the program. No intervention was applied to the patients in the control group. The data were evaluated using percentage distribution, arithmetic means, standard deviations, Chi-square and independent samples t-tests. The study found that patients in the experimental group showed a decrease in total mean scores on the BPRS and CDSS; the difference between the post-test scores of the experimental group and the post-test scores of the control group was statistically significant (p<0.05). The practice of relaxation exercises and music therapy was proven to be effective in reducing schizophrenic patients' psychological symptoms and levels of depression. Relaxation exercises and music therapy can be used as a complementary therapy in the medical treatment of patients with chronic schizophrenia. Copyright © 2016 Elsevier Inc. All rights reserved.

This research study was conducted to establish the influence of familiarization on the information component of movement in a motor task for the assessment of preschool children's motor skills. The sample included 50 children whose mean age was 5.9 years (71.5 months). The experimental group consisted of 27 children who were 5.9 years (71.5 months) old, and the control group consisted of 23 children who were 5.9 years (71.5 months) old. The examinees performed 2 motor tasks, standing long jump (SJ, explosive strength) and standing on 1 leg on a beam "flamingo test" (FT, balance). The experimental group underwent a period of familiarization with the motor task in 3 sessions with 5 trials every 3 days. The results indicate statistically significant differences in the final testing between both groups of examinees; the experimental group mean was 112.73 cm, and the control group mean was 100.62 in the SJ test (p = 0.00), and the experimental group mean was 27.10 seconds and the control group mean was 15.01 seconds in the FT (for balance) (p = 0.00). The results obtained in this research indicate that children significantly improved the results in the motor test of strength and balance, being influenced by familiarization. It was confirmed that it was necessary for preschool children to be familiar with the test and it is not justified to use testing and assessment protocols and standards for adults. Physical educators and coaches, when testing preschool children, should introduce children to tests to obtain the best result.

A total of 28 Holstein-Friesian calves were experimentally infected with 10(5)Giardia duodenalis cysts. Eleven days later, all animals were allocated into two groups of 14 animals each, based on the average pre-treatment cyst counts. Treatment was randomly assigned to one of the two groups, and all animals in the treatment group received a daily oral dosage of 15mg fenbendazole per kg bodyweight during 3 consecutive days. The calves in the control group received a placebo (water). From 3 days after treatment onwards, cyst excretion was determined three times a week during 4 consecutive weeks. The faecal consistency and general health were recorded on a daily basis, and all animals were weighed prior to treatment and weekly thereafter. At the end of the experimental period, there was a significant (P<0.001) reduction (98%) of the cumulative cyst excretion. There were no significant differences in general health between both groups, but faecal consistency was significantly lower (P<0.002) in the control group compared to the treatment group, although none of the animals displayed overt gastro-intestinal symptoms. Prior to treatment the weight did not differ between both experimental groups. At the end of the 4-week experimental period however, the animals in the treatment group gained on average 2.86kg (=102g per day) more than the animals in the control group (P<0.031). This study demonstrates for the first time a significant difference in weight gain between fenbendazole treated and untreated calves experimentally infected with G. duodenalis, although additional data need to confirm the need for treatment in natural conditions.

The goals of this study were to establish prevalence of subjective memory complaints (SMC) and depressive symptoms (DS) and their relation to cognitive functioning and cognitive status in an outpatient memory clinic cohort. Two hundred forty-eight cognitively healthy controls and 581 consecutive patients with cognitive complaints who fulfilled the inclusion criteria were included in the study. A statistically significant difference (p < 0.001) between control group and patient group regarding mean SMC was detected. 7.7% of controls reported a considerable degree of SMC, whereas 35.8% of patients reported considerable SMC. Additionally, a statistically significant difference (p < 0.001) between controls and patient group regarding Beck depression score was detected. 16.6% of controls showed a clinical relevant degree of DS, whereas 48.5% of patients showed DS. An analysis of variance revealed a statistically significant difference across all four groups (control group, SCI group, naMCI group, aMCI group) (p < 0.001). Whereas 8% of controls reported a considerable degree of SMC, 34% of the SCI group, 31% of the naMCI group, and 54% of the aMCI group reported considerable SMC. A two-factor analysis of variance with the factors cognitive status (controls, SCI group, naMCI group, aMCI group) and depressive status (depressed vs. not depressed) and SMC as dependent variable revealed that both factors were significant (p < 0.001), whereas the interaction was not (p = 0.820). A large proportion of patients seeking help in a memory outpatient clinic report considerable SMC, with an increasing degree from cognitively healthy elderly to aMCI. Depressive status increases SMC consistently across groups with different cognitive status.

It has been suggested that recall bias may explain the discrepant results between case-control and cohort studies on diet and the risk of breast cancer. Two control groups were used for this case-control study of 25 to 75-year-old breast cancer cases (n = 310). The first group consisted of population controls drawn from the Finnish National Population Register (n = 454). The second group consisted of women who were referred to the same examinations as were the cases because of clinical suspicion of breast disease but who were later diagnosed as healthy (referral controls; n = 506). Because the diagnosis was unknown at the time of interview, it was possible to assess by comparing the two control groups whether the self-reporting of diet changed under the threat of disease. Dietary habits were examined using a validated, self-administered food-frequency questionnaire. Premenopausal women misreported their consumption of liquid milk products, tea, and sugar. Reporting bias was also associated with the intake of fat and vitamins. Postmenopausal women misreported consumption of milk products. When recall bias was taken into consideration, milk was associated with increased risk of premenopausal breast cancer, whereas high consumption of poultry or high intake of monounsaturated fatty acids, n-3 fatty acids, n-6 fatty acids, and vitamin E were related to lower risk. The study suggested that oil, milk, cheese, coffee and beta-carotene may act as protective factors in postmenopausal women, whereas butter and cream may be risk factors for breast cancer. In summary, it is possible that some food items may be overreported or underreported under the threat of disease in health-conscious population. However, most of the results in this study were not modified by recall bias.

Platelets can modulate lymphocytes' role in the pathophysiology of thyroid autoimmune diseases. The present study was performed to clarify the status of platelet-lymphocyte subpopulations aggregation in circulating blood in patients with Graves' disease (GD). One hundred and fifty patients with GD (GD group) and 45 hyperthyroid patients with toxic multinodular goiter (TMG group) were recruited in the study. Control group consisted 150 healthy subjects. Immunophenotyping of lymphocytes was performed by flow cytometry. Detection of lymphocyte-platelet aggregates (LPAs) was done using light microscope after Ficoll-gradient centrifugation. The group of GD patients exhibited reduced CD8 lymphocyte and higher CD19 cell counts compared with TMG group and healthy controls. A greater number of activated CD3, HLA-DR+ lymphocytes were observed in GD than in TMG group and control group. GD group was characterized by lower blood platelet count (232 ± 89 × 10 cells/µL) than TMG group (251 ± 97 × 10 cells/µL; P < 0.05) and control group (262 ± 95 × 10 cells/µL; P < 0.05). In GD group, more platelet-bound lymphocytes (332 ± 91 /µL) were found than that in TMG group (116 ± 67/µL, P < 0.005) and control group (104 ± 58 /µL; P < 0.001). GD is associated with higher levels of activated lymphocytes and lymphocyte-platelet aggregates.

The hypolipidemic effect of red gram prebiotics of raffinose family oligosaccharides was studied in Wistar National Institute of Nutrition male rat strain. The study consisted of 36 rats randomly divided into three groups of 12 rats each. For 16 weeks, Group I was fed with the control diet; Group II was fed with a diet containing 3% standard raffinose as the reference group; Group III received the diet containing 3% red gram prebiotics. The results showed that the gain in body weight was low in the red gram prebiotics-supplemented group followed by the control group; highest increase of body weight was seen in the raffinose standard-fed group. Serum glucose levels of the red gram prebiotic-fed group decreased 14.92% compared to the control group and increased 2.07% compared to the reference group. The decrease in serum triglycerides (TG) levels of the red gram prebiotic-fed groups was 32.76% compared to the control group and 33.64% compared to the reference group. Decrease in the serum TC of the red gram-fed animals was 18.51% and 4.63% compared to the control group and the reference group, respectively. Increase in the level of serum high-density lipoprotein cholesterol (HDL-C) in the red gram-fed animals was 18.51% compared to the control group and 4.63% compared to the reference group. The present study can be a proof for the use of prebiotics as a preventive measure for overweight and obesity in humans, and legume prebiotics can be explored as a novel prebiotic product in the consumer market.

[Consistency and firmness in rearing practices of parents of adolescent drug addicts].

This paper deals with the increasingly popular theoretical approaches to drug addiction as a "family disease". Many theories have appeared claming that ethiopathogenic role related to the family environment is of crucial importance in juvenikle drug consumption. The main objective is to understand, trough consideration of one part of family dynamics, the etiological potential of the juvenile drug addiction. This work focuses only on certain parts of parents' upbringing and variations in their upbringing practices, namely their consistency and strictness, which has been shown to reflect in disfucntional family systems producing juvenile drug addicts. The author cosiders two essential aspect of the upbringing practice and, by using relevant evaluation tools of these standarts, attempts to measure their importance in relation to adolescents who suffer of drug addiction (experimental group) and those who never had any contact with narcotics (control group). A part of the EMBU questionaire has been applied, which is the adolescent's memory of his/her parents' upbringing practices in the childhood and pre-juvenile period. Only two issues, which deal with the parents' firmness and consistency, have been selected as results of this method. Examination has been carried out individualy and obtained data analized by the chi square test. The results indicate distinctive differences with respect to the consistency and strictness of the upbringing methods of drug addict in comparison to control group of the examined juvenile.

49 paranormal healers working by laying-on-of-hands (direct healing) and distance healing were compared with 56 nursing staff and a control group of 73 on the information-processing styles of field-dependence and reflexivity-impulsivity. Apparently paranormal healers scored as more field-dependent than the other groups which is consistent with observations of paranormal healers when working. No differences appeared among groups on reflexivity-impulsivity.

Enhanced Early Neuronal Processing of Food Pictures in Anorexia Nervosa: A Magnetoencephalography Study

PubMed Central

Scaife, Jessica C.; Park, Rebecca J.

2016-01-01

Neuroimaging studies in Anorexia Nervosa (AN) have shown increased activation in reward and cognitive control regions in response to food, and a behavioral attentional bias (AB) towards food stimuli is reported. This study aimed to further investigate the neural processing of food using magnetoencephalography (MEG). Participants were 13 females with restricting-type AN, 14 females recovered from restricting-type AN, and 15 female healthy controls. MEG data was acquired whilst participants viewed high- and low-calorie food pictures. Attention was assessed with a reaction time task and eye tracking. Time-series analysis suggested increased neural activity in response to both calorie conditions in the AN groups, consistent with an early AB. Increased activity was observed at 150 ms in the current AN group. Neuronal activity at this latency was at normal level in the recovered group; however, this group exhibited enhanced activity at 320 ms after stimulus. Consistent with previous studies, analysis in source space and behavioral data suggested enhanced attention and cognitive control processes in response to food stimuli in AN. This may enable avoidance of salient food stimuli and maintenance of dietary restraint in AN. A later latency of increased activity in the recovered group may reflect a reversal of this avoidance, with source space and behavioral data indicating increased visual and cognitive processing of food stimuli.

Virtual reality exposure therapy (VRET) realistically incorporates traumatic cues into exposure therapy and holds promise in the treatment of combat-related posttraumatic stress disorder (PTSD). In a randomized controlled trial of 92 Iraq and Afghanistan veterans and active duty military personnel with combat-related PTSD, we compared the efficacy of Trauma Management Therapy (TMT; VRET plus a group treatment for anger, depression, and social isolation) to VRET plus a psychoeducation control condition. Efficacy was evaluated at mid- and post-treatment, and at 3- and 6-month follow-up. Consistent with our hypothesis, VRET resulted in significant decreases on the Clinician Administered PTSD Scale and the PTSD Checklist-Military version for both groups. Also consistent with our hypothesis, significant decreases in social isolation occurred only for those participants who received the TMT group component. There were significant decreases for depression and anger for both groups, although these occurred after VRET and before group treatment. All treatment gains were maintained six-months later. Although not part of the original hypotheses, sleep was not improved by either intervention and remained problematic. The results support the use of VRET as an efficacious treatment for combat-related PTSD, but suggest that VRET alone does not result in optimal treatment outcomes across domains associated with PTSD.

Parietal cortex and episodic memory retrieval in schizophrenia.

PubMed

Lepage, Martin; Pelletier, Marc; Achim, Amélie; Montoya, Alonso; Menear, Matthew; Lal, Sam

2010-06-30

People with schizophrenia consistently show memory impairment on varying tasks including item recognition memory. Relative to the correct rejection of distracter items, the correct recognition of studied items consistently produces an effect termed the old/new effect that is characterized by increased activity in parietal and frontal cortical regions. This effect has received only scant attention in schizophrenia. We examined the old/new effect in 15 people with schizophrenia and 18 controls during an item recognition test, and neural activity was examined with event-related functional magnetic resonance imaging. Both groups performed equally well during the recognition test and showed increased activity in a left dorsolateral prefrontal region and in the precuneus bilaterally during the successful recognition of old items relative to the correct rejection of new items. The control group also exhibited increased activity in the dorsal left parietal cortex. This region has been implicated in the top-down modulation of memory which involves control processes that support memory-retrieval search, monitoring and verification. Although these processes may not be of paramount importance in item recognition memory performance, the present findings suggest that people with schizophrenia may have difficulty with such top-down modulation, a finding consistent with many other studies in information processing.

The viability of a fungal formulation using the nematode-trapping fungus Duddingtonia flagrans was assessed for the biological control of horse cyathostomin. Two groups (fungus-treated and control without fungus treatment), consisting of eight crossbred mares (3-18 years of age) were fed on Cynodon sp. pasture naturally infected with equine cyathostome larvae. Each animal of the treated group received oral doses of sodium alginate mycelial pellets (1g/(10 kg live weight week)), during 6 months. Significant reduction (p<0.01) in the number of eggs per gram of feces and coprocultures was found for animals of the fungus-treated group compared with the control group. There was difference (p<0.01) of 78.5% reduction in herbage samples collected up to (0-20 cm) between the fungus-treated group and the control group, during the experimental period (May-October). Difference of 82.5% (p<0.01) was found between the fungus-treated group and the control group in the sampling distance (20-40 cm) from fecal pats. During the last 3 months of the experimental period (August, September and October), fungus-treated mares had significant weight gain (p<0.01) compared with the control group, an increment of 38 kg. The treatment with sodium alginate pellets containing the nematode-trapping fungus D. flagrans reduced cyathostomin in tropical southeastern Brazil and could be an effective tool for biological control of this parasitic nematode in horses.

The Termination of Checking and the Role of Just Right Feelings: A Study of Obsessional Checkers Compared with Anxious and Non-clinical Controls.

Salkovskis, Paul M; Millar, Josie; Gregory, James D; Wahl, Karina

2017-03-01

Repeated checking in OCD can be understood from a cognitive perspective as the motivated need to achieve certainty about the outcome of a potentially risky action, leading to the application of Elevated Evidence Requirements (EER) and overuse of subjective criteria. Twenty-four obsessional checkers, 22 anxious controls, and 26 non-clinical controls were interviewed about and rated recent episodes where they felt (a) they needed to check and (b) checked mainly out of habit (i.e. not obsessionally). Both subjective and objective criteria were rated as significantly more important in obsessional checkers than in controls; obsessional checkers also used more criteria overall for the termination of the check, and rated more criteria as "extremely important" than the control groups. The termination of the check was rated as more effortful for obsessional checkers than for the comparison groups. Analysis of the interview data was consistent with the ratings. Feelings of "rightness" were associated with the termination of a check for obsessional checkers but not for controls. Results were consistent with the proposal that the use of "just right feelings" to terminate checking are related to EER.

The objective was to determine if lay-rescuers' acquisition of infant basic life support (BLS) skills would be better when skills teaching consisted of videotaping practice and providing feedback on performances, compared to conventional skills-teaching and feedback methods.   This pilot-exploratory, single-blind, prospective, controlled, randomized study was conducted on November 12, 2007, at the Rappaport Faculty of Medicine, Technion-Israel Institute of Technology, Haifa, Israel. The population under study consisted of all first-year medical students enrolled in the 2007-2008 year. BLS training is part of their mandatory introductory course in emergency medicine. Twenty-three students with previous BLS training were excluded. The remaining 71 were randomized into four and then two groups, with final allocation to an intervention and control group of 18 and 16 students, respectively. All the students participated in infant BLS classroom teaching. Those in the intervention group practiced skills acquisition independently, and four were videotaped while practicing. Tapes were reviewed by the group and feedback was provided. Controls practiced using conventional teaching and feedback methods. After 3 hours, all subjects were videotaped performing an unassisted, lone-rescuer, infant BLS resuscitation scenario. A skills assessment tool was developed. It consisted of 25 checklist items, grouped into four sections: 6 points for "categories" (with specific actions in six categories), 14 points for "scoring" (of accuracy of performance of each action), 4 points for "sequence" (of actions within a category), and 1 point for "order" of resuscitation (complete and well-sequenced categories). Two blinded expert raters were given a workshop on the use of the scoring tool. They further refined it to increase scoring consistency. The main outcome of the study was defined as evidence of better skills acquisition in overall skills in the four sections and in the specific skills sets for actions in any individual category. Data analysis consisted of descriptive statistics. Means and mean percentages were greater in the intervention group in all four sections compared to controls: categories (5.72 [95.33%] and 4.69 [92.66%]), scoring (10.57 [75.50%] and 7.41 [43.59%]), sequence (2.28 [57.00%] and 1.66 [41.50%]), and order of resuscitation (0.96 [96.00%] and 0.19 [19.00%]). The means and mean percentages of the actions (skill sets) in the intervention group were also larger than those of controls in five out of six categories: assessing responsiveness (1.69 [84.50%] and 1.13 [56.50%]), breathing technique (1.69 [93.00%] and 1.13 [47.20%]), chest compression technique (3.19 [77.50%] and 1.84 [46.00%]), activating emergency medical services (EMS) (3.00 [100.00%] and 2.81 [84.50%]), and resuming cardiopulmonary resuscitation (0.97 [97.00%] and 0.47 [47.00%]). These results demonstrate better performance in the intervention group. The use of videotaped practice and feedback for the acquisition of overall infant BLS skills and of specific skill sets is effective. Observation and participation in the feedback and assessment of nonexperts attempting infant BLS skills appeared to improve the ability of this group of students to perform the task. 2010 by the Society for Academic Emergency Medicine

Dynamic stability of the knee joint depends on the appropriate strength ratio of quadriceps and hamstring muscles. The purpose of this investigation was to determine the maximum peak torque (MPT) and MPT ratios of hamstrings to quadriceps (H/Q) muscles in patients with knee osteoarthritis (OA). Two groups of patients were included in the study. The first group consisted of 30 patients (Group A) with the clinical and radiologic findings of knee OA. The second group consisted of 30 patients (Group B) exhibiting knee joint pain without roentgenologic findings of knee OA. The findings of two patient groups were compared with each other and also with 30 healthy subjects (Group C). Isokinetic (at 60 degrees/s and at 180 degrees/s) and isometric (at 30 degrees and at 60 degrees of knee flexion) tests were performed by the rate-limiting isokinetic dynamometer system. Isokinetic and isometric MPT loss of knee flexors and extensors was found in both patient groups with respect to controls, but MPT ratios of H/Q muscles did not show a statistically significant difference compared with the control group. This may be related to the equal strength loss of knee flexors and knee extensors in patients with knee OA. It is concluded that strengthening exercises of hamstring muscles is as important as quadriceps strengthening in rehabilitation of knee OA.

The purpose of this study was to examine the effect of a rhythmic gymnastics program on the dynamic balance ability of a group of adults with intellectual disability (ID). The sample consisted of 18 adults with ID. The control group consisted of 8 adults and an intervention group of 10. The subjects were assigned to each group according to their desire to participate or not in the intervention program. Both groups were comparable in terms of age, weight, height, IQ, and socioeconomic background. The intervention group received a 12-week rhythmic gymnastics program at a frequency of 3 lessons per week, of 45 minutes. The methods of data collection included pre/post-test measurements of the dynamic balance for all subjects of both groups. The dynamic balance ability was measured by means of a balance deck (Lafayette) and was determined by the number of seconds the subject could remain standing on the platform of the stabilometer in durations of 30-, 45-, and 60-second intervals. As the results indicated, the intervention group showed a statistically significant improvement (p < 0.05) in terms of dynamic balance ability in each interval after the application of the rhythmic gymnastics program when compared with the control group. It is concluded that adults with ID can improve their balance ability with the application of a well-designed rhythmic gymnastics program.

The impact of stereotype threat and self-efficacy beliefs on neuropsychological test performance in a clinical traumatic brain injury (TBI) population was investigated. A total of 42 individuals with mild-to-moderate TBI and 42 (age-, gender-, educationally matched) healthy adults were recruited. The study consisted of a 2 (Type of injury: control, TBI) × 2 (Threat Condition: reduced threat, heightened threat) between-participants design. The purpose of the reduced threat condition was to reduce negative stereotyped beliefs regarding cognitive effects of TBI and to emphasize personal control over cognition. The heightened threat condition consisted of an opposing view. Main effects included greater anxiety, motivation, and dejection but reduced memory self-efficacy for head-injured-groups, compared to control groups. On neuropsychological testing, the TBI-heightened-threat-group displayed lower scores on Initial Encoding (initial recall) and trended toward displaying lower scores on Attention (working memory) compared to the TBI-reduced-threat-group. No effect was found for Delayed Recall measures. Memory self-efficacy mediated the relation between threat condition and neuropsychological performance, indicating a potential mechanism for the threat effect. The findings highlight the impact of stereotype threat and self-referent beliefs on neuropsychological test performance in a clinical TBI population.

This study examines the effectiveness of a wellness-based prevention program on elementary and junior high students' body image, personal attitudes, and eating behaviors. Group differences in measures of student attitudes and eating behaviors are examined to determine the effect of targeting different participant combinations (students, parents, and teachers) in 10 groups. For elementary schools, student participants consisted of control (no intervention) (n = 36), student only (n = 81), student/parent (n = 124), student/parent/teacher (n = 103), and parent/teacher (n = 149). For junior high schools, student participants consisted of control (n = 143), student only (n=215), student/parent (n=65), student/parent/teacher (n = 14), and parent/teacher (n = 177). Overall, complete data was available for 1,095 students, 114 parents and 92 teachers. Results indicate that self-concept and eating attitudes and behaviors were positively affected by participation in the program. For example, in elementary schools posttest scores on the behavior subscale of the self-concept measure are significantly higher for the student/parent/teacher group than for the control group. Results indicate that a one-time wellness-based eating disorder prevention program with students, which have in the past shown to be minimally effective, may be more effective in changing attitudes and behaviors when teachers and parents are involved.

The purpose of this study was to explore the effectiveness of a spiritual care training package in maternal caregivers of children with cancer. This study was a quasi-experimental study with pretest and posttest design consisting of a sample of 42 mothers of children diagnosed as having cancer. Participants were randomly assigned to either an experimental or a control group. The training package consisted of seven group training sessions offered in a children's hospital in Tehran. All mothers completed the Spirituality and Spiritual Care Rating Scale (SSCRS) and the Depression, Anxiety and Stress Scale (DASS-21) at pre and post test and after a three month follow up. There was significant difference between anxiety and spiritual, religious, Personalized care and total scores spiritual care between the intervention and control groups at follow-up (P<0.001).There was no statistically significant difference in stress and depression scores between the intervention and the control groups at follow-up. Findings show that spiritual care training program promotes spirituality, personalized care, religiosity and spiritual care as well as decreasing anxiety in mothers of children with cancer and decreases anxiety. It may be concluded that spiritual care training could be used effectively in reducing distressful spiritual challenges in mothers of children with cancer.

Antimicrobial methods of controlling dental caries that include probiotic agents can play a valuable role in establishing caries control in children at moderate to high risk for developing dental caries. Several studies have demonstrated the beneficial effects of use of various Probiotic products including curd. The objective of this study was to compare the effect of short-term consumption of probiotic curd containing Lactobacillus acidophilus and normal curd on salivary Streptococcus Mutans counts, as well as salivary pH. Forty, caries-free, 10-12 years old children were selected and randomly allocated to two groups. Test Group consisted of 20 children who consumed 200ml of probiotic curd daily for 30 days. Control Group consisted of 20 children who were given 200ml of regular curd for 30 days. Salivary pH and salivary Streptococcus Mutans counts were recorded at baseline and after 30 days and statistically compared using the Student's t-test. Consumption of probiotic curd resulted in a statistically significant reduction in S. Mutans colony counts (P<0.001) as compared to regular curd. However, there was a slight reduction in pH (P>0.05) in both the groups. Short-term consumption of probiotic curds can reduce oral S. Mutans counts. However, this caused a slight reduction in salivary pH.

To investigate the relationship between sarcopenia and diabetic nephropathy. 56 diabetic patients without complications, 50 diabetic patients with nephropathy, 53 healthy controls included in this present study. Demographic characteristics such as sex, age, anthropometric measurements such as weight, body mass index [BMI], hip circumference, waist circumference and upper arm circumference were measured. Sarcopenia diagnosis was based on European Working Group on Sarcopenia in Older People [EWGSOP] criteria which consist of hand grip strength, 6-meter walking test and muscle mass. The frequency of sarcopenia increased gradually from 15.1% in healthy control group to 21.4% in the diabetes group, and 34% in diabetic nephropathy group (X2 for trend, p = 0.029). The frequency of sarcopenia was similar in diabetes and diabetic nephropathy group. However, the frequency of sarcopenia was higher in diabetic nephropathy than healthy controls (OR = 2.89, CI [1.11-7.51] in logistic regression). In the present study, the prevalence of sarcopenia was higher in patients with diabetic nephropathy compared to healthy controls.

To evaluate facial asymmetry changes in pre-school patients with orofacial clefts after neonatal cheiloplasty and to compare facial asymmetry with age-matched healthy controls. The sample consisted of patients with unilateral cleft lip (UCL), unilateral cleft lip and palate (UCLP), and bilateral cleft lip and palate (BCLP). The patients were divided in two age groups with a mean age of 3 years (n = 51) and 4.5 years (n = 45), respectively, and 78 age-matched individuals as controls. Three-dimensional (3D) facial scans were analyzed using geometric morphometry and multivariate statistics. Geometric morphometry showed positive deviations from perfect symmetry on the right side of the forehead in the intervention groups and the controls. The UCL groups showed the greatest asymmetric nasolabial area on the cleft-side labia and the contralateral nasal tip. The UCLP group showed, moreover, asymmetry in buccal region due to typical maxillar hypoplasia, which was accentuated in the older group. The BCLP groups showed slightly similar but greater asymmetry than the control groups, except for the philtrum region. Asymmetry of each of the cleft groups significantly differed from the controls. Except for the buccal region in the UCLP and BCLP groups, asymmetry did not significantly increase with age. Copyright © 2018 Elsevier B.V. All rights reserved.

Falls are a major problem in the elderly population, but few communications address the influence of anesthesia on balance control. This study reports how a general balanced anesthesia (GBA) and a spinal anesthesia (SA) affect balance control in the elderly. We divided into three groups, according to electronystagmography findings and type of anesthesia, 21 men older than 65 years (mean age, 72 years) who were scheduled for prostate adenectomy. One group, designated GBN, consisted of normal subjects who underwent surgery under GBA. In another group, designated GBP, were pathological subjects who had clinically compensated central vestibular disorders (CVDs) and underwent surgery under GBA. The third group, designated SP, contained CVD patients who underwent surgery under SA. We assessed balance control via static posturography preoperatively and 48 hours postoperatively. We observed no change in balance control parameters (center of pressure distribution area [COPa] or COP sway velocity [SV]) for those patients in the GBN group or for those in the SP group. We did observe a significant difference for the patients in the GBP group, with higher postoperative values of COPa and SV (Wilcoxon signed rank test). Our results showed that in subjects with clinically compensated underlying CVD prior to a GBA, balance control worsens after the procedure, whereas no change in balance control occurs after an SA. Balance control in subjects with normal vestibuloocular function did not change even after a GBA.

Attributional Biases in Psychiatric Patients, a Religious, and a Control Group in the Assessment of a Hallucinatory Experience: The "White Christmas Test".

PubMed

Parra, Alejandro; Maschi, Gianina

The aim of this study was to evaluate the auditory hallucinatory experience in a clinical sample of patients with psychiatric symptoms (e.g. Schizophrenia), a religious group (eg. Christians) and a "control" group (with no mental disorder and non-religious). The sample consisted of individuals of both sexes. The patient sample was recruited in two psychiatric hospitals of Buenos Aires City, the religious from an evangelical cult, and people with no religious beliefs or previous psychiatric symptoms (control group). The Hallucinatory Experiences Questionnaire and the Oxford-Liverpool Inventory Feelings and Experiences were the measurement tools used. The White Christmas Test was also administered in order to assess the degree of vivid imagery hearing based on a version of signal detection paradigm in which the subjects think that they hear a song in the background of white noise. The results showed that patients showed greater attributional bias (compared with evangelicals and the control group), but the religious group also tended to show greater bias (although less) than the control group. In addition, patients tended to show greater schizotypal and hallucinatory experiences compared with the evangelicals and the control group, but surprisingly, the control group showed higher negative schizotypy than the religious group, which indicates that religious practices could help reduce the negative effects of schizotypy.

Regular physical exercise and healthy lifestyle can improve aerobic power of the elderly, although lung capacity gradually deteriorates with age. The aims of the study are: a) to evaluate the therapeutic effect of a treadmill exercise program on arterial blood oxygenation (SaO2), maximum oxygen consumption (VO2max) and maximum walking distance (MWD) in healthy elderly people; b) to examine the outcome of the program at a supervised short-term and at an unsupervised long-term. A prospective, not-randomized controlled intervention trial (NRCT) was conducted. Eighty participants were allocated into two homogeneous groups (training group, TG, n = 40; control group, CG, n = 40). Each group consisted of 20 men and 20 women. Pre-intervention measures of SaO2, VO2max and MWD were taken of each participant 1-week before the training program to establish the baseline. Also, during the training program, the participants were followed up at the 12, 30 and 48th week. The exercise program consisted of walking on a treadmill with fixed 0 % grade of inclination 3 times weekly for 48 weeks; the first 12 weeks were supervised and the remaining 36 weeks of the program were unsupervised. Participants in the control group were encouraged to walk twice a week during 45 min, and received standard recommendations for proper health. Related to the baseline, the SaO2, VO2max, and MWD is greater in the intervention group at the 12(th) (p <.001), 30(th) (p <.001) and 48(th) week (p <.001). Compared with the control group, there was also a significant improvement of SaO2, VO2max, and MWD valuesin the intervention group (p <.001) at the 12(th) (p <.001), 30(th) (p <.001) and 48(th) week (p <.001). Supervised intervention shows greater improvement of SaO2, VO2max, and MWD values than in the unsupervised one. These results show that performing moderate exercise, specifically walking 3 days a week, is highly recommended for healthy older people, improving aerobic power.

de Montigny, C; Chouinard, G; Annable, L

1979-11-01

In a double-blind placebo-controlled study, deanol acetamidobenzoate, administered in doses up to 1.5 g q.d. for three weeks to chronic schizophrenic patients presenting moderate to severe tardive dyskinesia, failed to alleviate the dyskinetic movements. However, there was a tendency for a significant increase in the schizophrenic symptoms of the deanol-treated group relative to the control group. The ineffectiveness of deanol in alleviating tardive dyskinesia is consistent with its inability to enhance brain acetylcholine synthesis. The worsening of the schizophrenic symptoms may possibly result from an interference by deanol with central cholinergic function.

Attention-deficit hyperactivity disorder (ADHD) is one of the most prevalent childhood psychiatric disorder, it affects around 3-12% of the children. ADHD is associated with numerous social and emotional impairments. Quality of life (QoL) studies of children with ADHD established low QoL in the most cases. Our aim was to examine QoL of children with ADHD according to the following aspects: age, children's self-report and parentproxy report, and we also would like to compare them with healthy control group along several dimensions of QoL. The clinical group consist of a treatmant naive group of children with ADHD, who were just diagnosed in the Vadaskert Hospital. The healthy control group consist of children from elementary schools. The children of control group do not have ADHD and do not stand under psychological or psychiatrical treatment. In our study we applied Mini International Neuropsychiatric Interview Kid and Intervertat Lebensqualitat Kindern und Jugendlichen questionare. Compared children with ADHD to healthy control group they have significantly lower QoL at many areas (school, peer realtions, generally) due their self report. By parent's proxy report children with ADHD have lower QoL according to all of the QoL domains. Parents of children with ADHD reported significantly lower QoL for their children in the most areas (school, family, peer realtion, mental state, generally) then the affected children. Adolescent with ADHD have lower QoL in 3 domains (school, peer relations, generally) than children with ADHD, while children with ADHD have lower QoL in one dimension (being alone) compared with adolescents with ADHD. Based on our results children with ADHD compared to healthy control group have lower QoL in many dimensions and there are age-related differences in the assessment of QoL. Additionally, our study draw the attention to the differences of QoL assessment between children and parents.

Effectiveness of a neuropsychological treatment for confabulations after brain injury: A clinical trial with theoretical implications

Confabulators consistently generate false memories without intention to deceive and with great feelings of rightness. However, to our knowledge, there is currently no known effective treatment for them. In order to fill this gap, our aim was to design a neuropsychological treatment based on current theoretical models and test it experimentally in 20 confabulators sequentially allocated to two groups: an experimental and a control group. The experimental group received nine sessions of treatment for three weeks (three sessions per week). The sessions consisted of some brief material that participants had to learn and recall at both immediate and delayed time points. After this, patients were given feedback about their performance (errors and correct responses). Pre- and post-treatment measurements were recorded. Confabulators in the control group were included in a waiting list for three weeks, performed the pre- and post- measurements without treatment, and only then received the treatment, after which a post-treatment measurement was recorded. This applied to only half of the participants; the other half quit the study prematurely. Results showed a significant decrease in confabulations and a significant increase in correct responses in the experimental group; by contrast, patients in the control group did not improve during the waiting list period. Only control group patients who subsequently received the treatment after serving as controls improved. The effects of the treatment were generalized to patients’ everyday lives, as reported by relatives, and persisted over time. This treatment seems to be effective and easy to implement and consequently of clinical interest. Moreover, it also has theoretical implications regarding the processes related to the genesis and/or maintenance of confabulations. In particular, results point to a deficit in early stages of memory retrieval with the preservation of later strategic monitoring processes. Specifically, some of the processes involved may include selective attention or early conflict detection deficits. Future research should test these hypotheses. PMID:28257420

This study was conducted to develop and to determine the effects of an integrated symptom management program for prevention of recurrent cardiac events after percutaneous coronary intervention. Subjects consisted of 58 CAD patients (experimental group: 30, control group: 28). The experimental group participated in an integrated symptom management program for 6 months which was composed of tailored education, stress management, exercise, diet, deep breathing, music therapy, periodical telephone monitoring and a daily log. The control group received the usual care. The experimental group significantly decreased symptom experiences and the level of LDL compared to the control group. The experimental group significantly increased self care activity and quality of life compared to the control group. Although no significant difference was found in cardiac recurrence, the experimental group had fewer recurrences. These results suggest that an integrated symptom management program for prevention of recurrent cardiac events after percutaneous coronary intervention can improve symptom aggravation, recurrent rate, self care activity and quality of life. Nursing interventions are needed to maintain and further enhance the quality of life of these patients and the interventions should be implemented in the overall transition period.

The objective of the study was to investigate the effects of a galacto-oligosaccharides (GOS)-supplemented formula on the intestinal microbiota in healthy term infants, with a specific consideration for gastrointestinal symptoms as colic, stool frequency and consistency, regurgitation. This was a randomized, double-blind, controlled, parallel-group clinical trial performed simultaneously by 6 centers in Italy. Three groups were considered: breastfed, formula-fed, and GOS-supplemented formula-fed infants. Formula-fed infants were randomized to receive either the control or the study formula and consume the assigned formula exclusively until the introduction of complementary feeding. The nutritional composition of the 2 formulas were identical, apart from the supplemented GOS (0.4 g/100 mL) in the study formula. Four different types of bacteria were evaluated in order to assess the efficacy of GOS-supplemented formula on infants: Bifidobacterium, Lactobacillus, and Clostridium, Escherichia coli. A total of 199 breastfed infants and 163 formula-fed infants were recruited. When considering stool frequency and consistency, GOS-supplemented formula presented normal and soft stools in the majority of episodes (89%). In the supplemented group the incidence of colic was lower with respect to the control group. A significantly lower count of Clostridium and a higher count of Bifidobacterium were found when comparing study formula and control formula in infants with colic. In children with colic the ratio between Clostridium count and Bifidobacterium and Lactobacillus count was in favor of the latter two when considering the GOS-supplemented formula group with respect to the control one. The prebiotic-supplemented formula mimicked the effect of human milk in promoting Bifidobacterium and Lactobacillus growth and in inhibiting Clostridium growth, resulting in a significantly lower presence of colic.

The comparative experience of mechanical and manual intestinal anastomoses in newborns was analyzed. The main group (mechanical suture) consisted of 23 patients; the group of control consisted of 21 little patients. The mechanical intestinal suture was performed with the use of linear endoscopic stapler with 2.5 mm high staples. There were no differences in age and body weight between the two groups. The mean operative time was 77.4 min for the 1st group, whereas for the 2nd group it was 56.4 min. There were no significant difference in time before enteral feeding after the operation - 6.7 days on average. The hospital stay time was also identical (13.3 vs. 14.1 days). Postoperative period was uncomplicated in both groups. Thus, the use of mechanical stapler for intestinal anastomosis allows shorten the operative time, though preserving the same results of hospital stay and enteral feeding beginning.

The problem of cancer-related pain afflicts millions of people annually. The study described here was aimed at improving cancer patients' pain control through a planned patient education program. A randomized clinical trial with a Solomon Four-Group design was used to assess the effectiveness of a patient education intervention consisting of nurse counseling and printed materials. The sample included 230 cancer patients. One month later, patients in the experimental group were more likely to have taken their pain medicine on the correct schedule and to have taken the correct dosage. The experimental group also was significantly less likely to report stopping the medicine when they felt better. In addition, they were significantly less worried about tolerance and addiction to pain medicines. Forty-four percent of the experimental group compared to 24% of the control group reported no or mild pain at the posttest.

Effects of an intervention with teachers in the physical education context: A Self-Determination Theory approach

PubMed Central

2017-01-01

Framed within Self-Determination Theory, the purpose of the present study was to test the effects of a training program with physical education (PE) teachers. Participants were 21 high school PE teachers (experimental group, n = 10; control group, n = 11), and their 836 students, aged 12 to 16 years. Teachers in the experimental group received a training program consisting of strategies to support autonomy, competence, and relatedness need satisfaction. A repeated measures ANCOVA was carried out for each dependent variable. After the intervention, students in the experimental group significantly increased their scores on autonomy support, relatedness support, autonomy satisfaction, autonomous motivation, controlled motivation, and intention to be physically active, as compared to the control group. These findings emphasize the utility of a training program with PE teachers to promote the students’ psychological need satisfaction, and hence, self-determined motivation toward PE classes.

This study consisted of a survey given to college students (N = 560) at a rural university in the Pacific Northwest. The sample was randomly assigned into four groups, following the Solomon four-group study design. The two levels of treatment included interventions consisting of a visit to the AIDS Memorial Quilt for the experimental groups and attendance at an unrelated event for the control groups. Pretests were completed 4 weeks prior to interventions; posttests were completed by the entire sample 4 weeks after the interventions. Results confirmed expected differences among the four groups in terms of social distance, perceptions of people with AIDS, self-efficacy, and discussion of risky behavior. The results suggest that the AIDS Memorial Quilt addresses issues centrally related to behavior change and indicates support for the message interpretation process and stages of change models.

Dissociative identity disorder and prepulse inhibition of the acoustic startle reflex

A group of persons with dissociative identity disorder (DID) was compared with a group of persons with other dissociative disorders, and a group of nondiagnosed controls with regard to prepulse inhibition (PPI) of the acoustic startle reflex. The findings suggest maladaptive attentional processes at a controlled level, but not at a preattentive automatic level, in persons with DID. The prepulse occupied more controlled attentional resources in the DID group compared with the other two groups. Preattentive automatic processing, on the other hand, was normal in the DID group. Moreover, startle reflexes did not habituate in the DID group. In conclusion, increased PPI and delayed habituation is consistent with increased vigilance in individuals with DID. The present findings of reduced habituation of startle reflexes and increased PPI in persons with DID suggest the operation of a voluntary process that directs attention away from unpleasant or threatening stimuli. Aberrant voluntary attentional processes may thus be a defining characteristic in DID. PMID:18830396

The purpose of the study was to investigate the effectiveness of case-based learning instruction over traditionally designed chemistry instruction on eleventh grade students' epistemological beliefs and their attitudes toward chemistry as a school subject. The subjects of this study consisted of 63 eleventh grade students from two intact classes of an urban high school instructed with same teacher. Each teaching method was randomly assigned to one class. The experimental group received case-based learning and the control group received traditional instruction. At the experimental group, life cases were presented with small group format; at the control group, lecturing and discussion was carried out. The results showed that there was a significant difference between the experimental and control group with respect to their epistemological beliefs and attitudes toward chemistry as a school subject in favor of case-based learning method group. Thus, case base learning is helpful for development of students' epistemological beliefs and attitudes toward chemistry.

To validate the construct and discriminant properties of a hospital infection prevention and control program. The program consisted of four indicators: technical-operational structure; operational prevention and control guidelines; epidemiological surveillance system; and prevention and control activities. These indicators, with previously validated content, were applied to 50 healthcare institutions in the city of São Paulo, Southeastern Brazil, in 2009. Descriptive statistics were used to characterize the hospitals and indicator scores, and Cronbach's α coefficient was used to evaluate the internal consistency. The discriminant validity was analyzed by comparing indicator scores between groups of hospitals: with versus without quality certification. The construct validity analysis was based on exploratory factor analysis with a tetrachoric correlation matrix. The indicators for the technical-operational structure and epidemiological surveillance presented almost 100% conformity in the whole sample. The indicators for the operational prevention and control guidelines and the prevention and control activities presented internal consistency ranging from 0.67 to 0.80. The discriminant validity of these indicators indicated higher and statistically significant mean conformity scores among the group of institutions with healthcare certification or accreditation processes. In the construct validation, two dimensions were identified for the operational prevention and control guidelines: recommendations for preventing hospital infection and recommendations for standardizing prophylaxis procedures, with good correlation between the analysis units that formed the guidelines. The same was found for the prevention and control activities: interfaces with treatment units and support units were identified. Validation of the measurement properties of the hospital infection prevention and control program indicators made it possible to develop a tool for evaluating these programs in an ethical and scientific manner in order to obtain a quality diagnosis in this field.

This study was designed to determine the effects of health coaching and mediating variables on quantitative aspect of health in low-income hypertensive people. The experimental group for the current study consisted of 21 clients who received health coaching services, and the control group consisted of 22 clients who received home-visiting nursing services. Two groups received health coaching or homevisiting nursing services once a week for 8 weeks. The evaluation variables were self-efficacy, nutrition management, health behaviors, self-rated health, and quality of life. The results revealed that the level of nutrition management was significantly higher in the experimental group than the control group (F=10.33, p=.005). These results confirm that health coaching is a useful strategy that encourages clients to continuously maintain their own health behaviors. Thus, the findings of the current study provide useful data for establishing measures for the health management of those afflicted with chronic disease, such as hypertension. Furthermore, health coaching may be developed into useful intervention strategies for dealing with chronic diseases and improving home-visiting nursing. © 2017 Korean Society of Nursing Science

Factors contributing to the pathogenesis of decompression sickness (DCS) in divers have been described in many studies. However, relative importance of these factors has not been reported. In this case-control study, we compared the diving profiles of divers experiencing DCS with those of a control group. The DCS group comprised 35 recreational scuba divers who were diagnosed by physicians as having DCS. The control group consisted of 324 apparently healthy recreational divers. All divers conducted their dives from 2009 to 2011. The questionnaire consisted of 33 items about an individual's diving profile, physical condition and activities before, during and just after the dive. To simplify dive parameters, the dive site was limited to Izu Osezaki. Odds ratios and multiple logistic regression were used for the analysis. Odds ratios revealed several items as dive and health factors associated with DCS. The major items were as follows: shortness of breath after heavy exercise during the dive (OR = 12.12), dehydration (OR = 10.63), and maximum dive depth > 30 msw (OR = 7.18). Results of logistic regression were similar to those by odds ratio analysis. We assessed the relative weights of the surveyed dive and health factors associated with DCS. Because results of several factors conflict with previous studies, future studies are needed.

To assess the efficiency and treatment outcome of patients treated with corticotomy-assisted en-masse orthodontic retraction as compared with the en-masse retraction without corticotomy. Forty adult patients with bimaxillary protrusion requiring correction of bidental proclination constituted the sample. The study group consisted of 22 patients (male 11, female 11) willing to undergo surgery to reduce the duration of their orthodontic treatment and 18 patients (male 9, female 9) desirous of undergoing conventional orthodontic treatment without surgical intervention constituted the control group. Comparison of rate of retraction and anchor loss between the study and the control group was assessed. Average rate of space closure of 1.8 mm/month in the maxilla and 1.57 mm/month in the mandible was observed in the study group compared to 1.02 mm/month in the maxilla and 0.87 mm/month in the mandible in the control group. The rate of retraction accelerated during the first 2 months of retraction. Molar anchor loss of approximately 0.6 mm occurred in the study group, and 1.8 mm occurred in the control group during the 4 months. The rate of retraction with study group was twice as faster when compared to the control group, accelerating during the first 2 months of retraction. There was better anchorage control with the undecorticated molar segment during the retraction period but was found to increase as time advanced.

Recurrent pregnancy loss (RPL) is defined by two or more failed clinical pregnancies. Three to four percent of the couples with RPL have chromosomal aberrations (CA) in at least one partner. The parent's structural chromosomal abnormalities may cause an unbalanced karyotype in the conceptus which could lead to implantation failure, early or late pregnancy loss, or delivery of a child with severe physical and/or mental disabilities. To compare live birth rates of couples with CA to couples with normal karyotypes and to investigate medical and obstetric characteristics and pregnancy outcomes of couples with CA and RPL who attend an RPL clinic at a tertiary hospital. A retrospective cohort study, including 349 patients with two or more consecutive pregnancy losses. The study group consisted of 52 patients with CA, and the control group consisted of 297 couples with normal karyotype. All patients were evaluated and treated in the RPL clinic at Soroka University Medical Center and had at least one subsequent spontaneous pregnancy. The demographic and clinical characteristics were not found to be statistically different between the two groups. The group of carriers of CA had 28/52 (53.8%) live births in their index pregnancy vs. the normal 202/297 (68%) (P=0.067, CI 95%) in the control group. No statistically significant etiology was found between the study group and the control group. A statistically significant difference in live birth rates was found when comparing the total amount of pregnancies [index pregnancy (IP)+post index pregnancy (PIP)] between the study group and the control group (54.16% vs. 67.82%, respectively, P=0.0328). Patients with RPL and CA who have spontaneous pregnancies, have a good prognosis (63.4%) of a successful pregnancy with at least one of the pregnancies (index or post index) resulting in a live birth.

BACKGROUND In the Medicare Shared Savings Program (MSSP), accountable care organizations (ACOs) have financial incentives to lower spending and improve quality. We used quasi-experimental methods to assess the early performance of MSSP ACOs. METHODS Using Medicare claims from 2009 through 2013 and a difference-in-differences design, we compared changes in spending and in performance on quality measures from before the start of ACO contracts to after the start of the contracts between beneficiaries served by the 220 ACOs entering the MSSP in mid-2012 (2012 ACO cohort) or January 2013 (2013 ACO cohort) and those served by non-ACO providers (control group), with adjustment for geographic area and beneficiary characteristics. We analyzed the 2012 and 2013 ACO cohorts separately because entry time could reflect the capacity of an ACO to achieve savings. We compared ACO savings according to organizational structure, baseline spending, and concurrent ACO contracting with commercial insurers. RESULTS Adjusted Medicare spending and spending trends were similar in the ACO cohorts and the control group during the precontract period. In 2013, the differential change (i.e., the between-group difference in the change from the precontract period) in total adjusted annual spending was −$144 per beneficiary in the 2012 ACO cohort as compared with the control group (P = 0.02), consistent with a 1.4% savings, but only −$3 per beneficiary in the 2013 ACO cohort as compared with the control group (P = 0.96). Estimated savings were consistently greater in independent primary care groups than in hospital-integrated groups among 2012 and 2013 MSSP entrants (P = 0.005 for interaction). MSSP contracts were associated with improved performance on some quality measures and unchanged performance on others. CONCLUSIONS The first full year of MSSP contracts was associated with early reductions in Medicare spending among 2012 entrants but not among 2013 entrants. Savings were greater in independent primary care groups than in hospital-integrated groups. PMID:27075832

An experimental demonstration of stem damage as a predictor of fire-caused mortality for ponderosa pine

van Mantgem, P.; Schwartz, M.

2004-01-01

We subjected 159 small ponderosa pine (Pinus ponderosa Dougl. ex P. & C. Laws.) to treatments designed to test the relative importance of stem damage as a predictor of postfire mortality. The treatments consisted of a group with the basal bark artificially thinned, a second group with fuels removed from the base of the stem, and an untreated control. Following prescribed burning, crown scorch severity was equivalent among the groups. Postfire mortality was significantly less frequent in the fuels removal group than in the bark removal and control groups. No model of mortality for the fuels removal group was possible, because dead trees constituted <4% of subject trees. Mortality in the bark removal group was best predicted by crown scorch and stem scorch severity, whereas death in the control group was predicted by crown scorch severity and bark thickness. The relative lack of mortality in the fuels removal group and the increased sensitivity to stem damage in the bark removal group suggest that stem damage is a critical determinant of postfire mortality for small ponderosa pine.

The effects of an integrated Algebra 1/physical science curriculum on student achievement in Algebra 1, proportional reasoning and graphing abilities

The purpose of this investigation was to determine if an integrated curriculum in algebra 1/physical science facilitates acquisition of proportional reasoning and graphing abilities better than a non-integrated, traditional, algebra 1 curriculum. Also, this study was to ascertain if the integrated algebra 1/physical science curriculum resulted in greater student achievement in algebra 1. The curriculum used in the experimental class was SAM 9 (Science and Mathematics 9), an investigation-based curriculum that was written to integrate physical science and basic algebra content. The experiment was conducted over one school year. The subjects in the study were 61 ninth grade students. The experimental group consisted of one class taught concurrently by a mathematics teacher and a physical science teacher. The control group consisted of three classes of algebra 1 students taught by one mathematics teacher and taking physical science with other teachers in the school who were not participating in the SAM 9 program. This study utilized a quasi-experimental non-randomized control group pretest-posttest design. The investigator obtained end-of-algebra 1 scores from student records. The written open-ended graphing instruments and the proportional reasoning instrument were administered to both groups as pretests and posttests. The graphing instruments were also administered as a midtest. A two sample t-test for independent means was used to determine significant differences in achievement on the end-of-course algebra 1 test. Quantitative data from the proportional reasoning and graphing instruments were analyzed using a repeated measures analysis of variance to determine differences in scores over time for the experimental and control groups. The findings indicate no significant difference between the experimental and control groups on the end-of-course algebra 1 test. Results also indicate no significant differences in proportional reasoning and graphing abilities between the two groups over time. However, all subjects (experimental and control groups) made significant improvement in graphing abilities over one school year. In this study, students participating in an investigation-based curriculum integrating algebra 1 and physical science performed as well on the instruments as the students in the traditional curriculum. Therefore, an argument can be made that instruction using an integrated curriculum (algebra l/physical science) is a viable alternative to instruction using a more traditional algebra 1 curriculum. Finally, the integrated curriculum adheres to the constructivist theoretical perspective (Krupnik-Gotlieb, 1995) and is more consistent with recommendations in the NCTM Standards (1992) than the traditional curriculum.

We randomly assigned 62 patients scheduled for total hip arthroplasty to the following IV dosing schedule: 1) placebo at induction, at wound closure, and 12 h after induction (control); 2) parecoxib 40 mg at induction, placebo at wound closure, and parecoxib 40 mg 12 h after induction (pre); or, 3) placebo at induction, parecoxib 40 mg at wound closure, and parecoxib 40 mg 12 h after induction (post). Pain scores at rest and with movement were recorded every 4 h for 24 h using a visual analog scale. Treatment side effects were recorded every 4 h. Red cell loss for 5 days after surgery was calculated. Postoperative pain scores were less in the pre and post groups than in the control group. Postoperative bleeding was similar in the three groups. There were no significant differences between the pre and post groups, nor was their any trend suggesting a preemptive analgesic efficacy from preincision administration of parecoxib. Morphine use in the Postanesthesia Care Unit was reduced in the pre and post groups compared with the control group (14.2 +/- 2.0, and 15.7 +/- 2.0, vs 20.4 +/- 2.3 mg), although the trend was only significant (P < 0.05) in the pre group. The first pain score was also reduced in the pre and post groups compared to the control group (56.1 +/- 7.5 and 64.2 +/- 7.0 vs 78.3 +/- 5), but this was also only significant for the pre group (P = 0.001). The delay for first analgesic demand was increased for both the pre and post group compared to the control group (38 +/- 9 and 28.2 +/- 6.6 vs 18 +/- 6 min) but, again, this was only significant for the pre group (P = 0.05). Twenty-four hour consumption of morphine was similar in the pre (26 +/- 12 mg) and post groups (25 +/- 13 mg); both were significantly less than in the control group (47 +/- 27 mg, P < 0.001). Administration of parecoxib before hip arthroplasty did not provide preemptive analgesia. There was a trend towards improved analgesia immediately after surgery with preincision administration, consistent with the expected time course of nonsteroidal antiinflammatory drug's effect. Perioperative parecoxib administration, consisting of two injections spaced 12 h apart, improved postoperative analgesia over the first 24 h without increasing bleeding.

The purpose of this study was to test the effectiveness of an online problem-based learning (e-PBL) program that offers multimedia scenarios to develop sexual health care competencies. A pretest–posttest control group design was used with two randomized groups in one Korean tertiary hospital. The sample included 32 RNs who cared for oncology patients. The intervention group completed an e-PBL cycle consisting of eight tutorials. Nurses in the intervention group scored significantly higher on knowledge than did those in the control group. The intervention group exhibited no significant differences in attitude and practices following the intervention. The results show the potential of e-PBL to enhance traditional PBL by offering multimedia scenarios in an interactive and flexible learning environment.

Timing variability of reach trajectories in left versus right hemisphere stroke.

2011-10-24

This study investigated trajectory timing variability in right and left stroke survivors and healthy controls when reaching to a centrally located target under a fixed target condition or when the target could suddenly change position after reach onset. Trajectory timing variability was investigated with a novel method based on dynamic programming that identifies the steps required to time warp one trial's acceleration time series to match that of a reference trial. Greater trajectory timing variability of both hand and joint motions was found for the paretic arm of stroke survivors compared to their non-paretic arm or either arm of controls. Overall, the non-paretic left arm of the LCVA group and the left arm of controls had higher timing variability than the non-paretic right arm of the RCVA group and right arm of controls. The shoulder and elbow joint warping costs were consistent predictors of the hand's warping cost for both left and right arms only in the LCVA group, whereas the relationship between joint and hand warping costs was relatively weak in control subjects and less consistent across arms in the RCVA group. These results suggest that the left hemisphere may be more involved in trajectory timing, although the results may be confounded by skill differences between the arms in these right hand dominant participants. On the other hand, arm differences did not appear to be related to differences in targeting error. The paretic left arm of the RCVA exhibited greater trajectory timing variability than the paretic right arm of the LCVA group. This difference was highly correlated with the level of impairment of the arms. Generally, the effect of target uncertainty resulted in slightly greater trajectory timing variability for all participants. The results are discussed in light of previous studies of hemispheric differences in the control of reaching, in particular, left hemisphere specialization for temporal control of reaching movements.

The prevention and treatment of childhood obesity is a key public health challenge. However, certain groups within populations have markedly different risk profiles for obesity and related health behaviours. Well-designed subgroup analysis can identify potential differential effects of obesity interventions, which may be important for reducing health inequalities. The study aim was to evaluate the consistency of the effects of active video games across important subgroups in a randomised controlled trial (RCT). A two-arm, parallel RCT was conducted in overweight or obese children (n=322; aged 10-14 years) to determine the effect of active video games on body composition. Statistically significant overall treatment effects favouring the intervention group were found for body mass index, body mass index z-score and percentage body fat at 24 weeks. For these outcomes, pre-specified subgroup analyses were conducted among important baseline demographic (ethnicity, sex) and prognostic (cardiovascular fitness) groups. No statistically significant interaction effects were found between the treatment and subgroup terms in the main regression model (p=0.36 to 0.93), indicating a consistent treatment effect across these groups. Preliminary evidence suggests an active video games intervention had a consistent positive effect on body composition among important subgroups. This may support the use of these games as a pragmatic public health intervention to displace sedentary behaviour with physical activity in young people.

To examine the effectiveness of aquatic exercise training on fatigue and health-related quality of life (HRQOL) in women with multiple sclerosis (MS). Randomized controlled trial, 4-week and 8-week follow-up. Referral center of a multiple sclerosis society. Women (N=32) diagnosed with relapsing-remitting MS (mean age ± SD, 32.6±8.0y) were recruited into this study. After undergoing baseline testing by a neurologist, participants were randomly assigned to either an intervention (aquatic exercise) or a control group. The intervention consisted of 8 weeks supervised aquatic exercise in a swimming pool (3 times a week, each session lasting 60min). At baseline, 4 weeks, and 8 weeks, fatigue and HRQOL were assessed by a blind assessor using the Modified Fatigue Impact Scale and the Multiple Sclerosis Quality of Life-54 questionnaire, respectively. A mixed-model approach to repeated-measures analysis of variance was used to detect within- and between-subject effects. Findings are based on 21 patients (10 from the exercise group and 11 from the control group) who had data available on outcomes. There was no significant difference between the 2 groups at the baseline. Patients in the aquatic exercise group showed significant improvements in fatigue and subscores of HRQOL after 4 and 8 weeks compared with the control group. Results obtained from the intention-to-treat analysis were consistent with those of per-protocol analysis. The findings suggest that aquatic exercise training can effectively improve fatigue and HRQOL of patients with MS and should be considered in the management of this relatively common public health problem.

Biased and less sensitive: A gamified approach to delay discounting in heroin addiction.

People with addiction will continue to use drugs despite adverse long-term consequences. We hypothesized (a) that this deficit persists during substitution treatment, and (b) that this deficit might be related not only to a desire for immediate gratification, but also to a lower sensitivity for optimal decision making. We investigated how individuals with a history of heroin addiction perform (compared to healthy controls) in a virtual reality delay discounting task. This novel task adds to established measures of delay discounting an assessment of the optimality of decisions, especially in how far decisions are influenced by a general choice bias and/or a reduced sensitivity to the relative value of the two alternative rewards. We used this measure of optimality to apply diffusion model analysis to the behavioral data to analyze the interaction between decision optimality and reaction time. The addiction group consisted of 25 patients with a history of heroin dependency currently participating in a methadone maintenance program; the control group consisted of 25 healthy participants with no history of substance abuse, who were recruited from the Western Sydney community. The patient group demonstrated greater levels of delay discounting compared to the control group, which is broadly in line with previous observations. Diffusion model analysis yielded a reduced sensitivity for the optimality of a decision in the patient group compared to the control group. This reduced sensitivity was reflected in lower rates of information accumulation and higher decision criteria. Increased discounting in individuals with heroin addiction is related not only to a generally increased bias to immediate gratification, but also to reduced sensitivity for the optimality of a decision. This finding is in line with other findings about the sensitivity of addicts in distinguishing optimal from nonoptimal choice options.

Structural and functional properties of hemoglobins from unicellular organisms as revealed by resonance Raman spectroscopy.

PubMed

Egawa, Tsuyoshi; Yeh, Syun-Ru

2005-01-01

Hemoglobins have been discovered in organisms from virtually all kingdoms. Their presence in unicellular organisms suggests that the gene for hemoglobin is very ancient and that the hemoglobins must have functions other than oxygen transport, in view of the fact that O2 delivery is a diffusion-controlled process in these organisms. Based on sequence alignment, three groups of hemoglobins have been characterized in unicellular organisms. The group-one hemoglobins, termed truncated hemoglobins, consist of proteins with 110-140 amino acid residues and a novel two-over-two alpha-helical sandwich motif. The group-two hemoglobins, termed flavohemoglobins, consist of a hemoglobin domain, with a classical three-over-three alpha-helical sandwich motif, and a flavin-containing reductase domain that is covalently attached to it. The group-three hemoglobins consist of myoglobin-like proteins that have high sequence homology and structural similarity to the hemoglobin domain of flavohemoglobins. In this review, recent resonance Raman studies of each group of these proteins are presented. Their implications are discussed in the context of the structural and functional properties of these novel hemoglobins.

The aims of our study were to compare quality of life (QOL) in obese patients after bariatric surgery with that in controls seeking surgery and to investigate which factors are associated with QOL in the Moorehead-Ardelt Quality of Life Questionnaire II (MA II). This was a cross-sectional study. The operated group consisted of patients after laparoscopic sleeve gastrectomy or laparoscopic Roux-en-Y gastric bypass. The MA II was administered by e-mail to 305 patients 12-18 months after surgery. The control groups consisted of 101 obese patients. We compared the QOL scores and considered good and very good outcomes to be satisfactory. Multiple logistic regression and correlation analysis was performed to identify factors associated with QOL. In the operated group, the total MA II score was 1.70 ± 0.76, which was higher than 0.59 ± 1.17 in the control group. The score adjusted for the type of surgery was comparable. The prevalence of satisfactory QOL outcomes was similar in both post-operative subgroups and was still higher than in the control group. We identified four factors associated with higher QOL in obese patients. Weight loss was not correlated with total score in MAII. This study demonstrates that patients after bariatric surgery have a higher score in MA II, which reflects better QOL. The scoring adjusted by type of operation is comparable. QOL among obese patients is dependent on age, gender, history of bariatric surgery, and partnered status. Body mass reduction was not associated with outcome in MAII.

Total knee arthroplasty (TKA) is a common procedure resulting in significant post-operative pain. Percutaneous cryoneurolysis targeting the infrapatellar branch of the saphenous nerve and anterior femoral cutaneous nerve could relieve post-operative knee pain by temporarily blocking sensory nerve conduction. A retrospective chart review of 100 patients who underwent TKA was conducted to assess the value of adding perioperative cryoneurolysis to a multimodal pain management program. The treatment group consisted of the first 50 patients consecutively treated after the practice introduced perioperative (five days prior to surgery) cryoneurolysis as part of its standard pain management protocol. The control group consisted of the 50 patients treated before cryoneurolysis was introduced. Outcomes included hospital length of stay (LOS), post-operative opioid requirements, and patient-reported outcomes of pain and function. A significantly lower proportion of patients in the treatment group had a LOS of ≥2days compared with the control group (6% vs. 67%, p<0.0001) and required 45% less opioids during the first 12weeks after surgery. The treatment group reported a statistically significant reduction in symptoms at the six- and 12-week follow-up compared with the control group and within-group significant reductions in pain intensity and pain interference at two- and six-week follow-up, respectively. Perioperative cryoneurolysis in combination with multimodal pain management may significantly improve outcomes in patients undergoing TKA. Promising results from this preliminary retrospective study warrant further investigation of this novel treatment in prospective, randomized trials. III. Copyright © 2016 The Authors.

2016-01-01

Background Early cochlear implantation aids auditory feedback and supports better communication and self-monitoring of the voice. The objective of this study was to determine whether the age of cochlear implantation has an impact on vocal development in children implanted before age 4. Method and procedures The study consisted of 19 participants in total. All implant recipients (experimental group) were 3–5 years post-implantation, including four prelingual (0–2 years) and five perilingual (2–4 years) implant recipients. The control group consisted of 10 children whose hearing was within normal limits between the ages 3–6 years and 10 months, which was compared to the experimental group. Established paediatric norms were used for additional comparison. A questionnaire was used to gather information from each of the participant’s caregivers to determine whether other personal and contextual factors had an impact on voice production. An acoustic analysis was conducted for each participant using the Multi-Dimensional Voice Program of the Computerized Speech Lab. Results When the experimental group and the control group were compared, similar results were yielded for fundamental frequency and short-term perturbation (jitter and shimmer). More variability was noted in long-term frequency and amplitude measures, with significantly higher differences, and therefore further outside the norms, in the prelingual group when compared to the perilingual and control groups. Conclusion In this study, age of implantation did not impact vocal characteristics. Further research should include larger sample sizes, with participants that are age and gender matched.

Pritchard, Verena E; Neumann, Ewald; Rucklidge, Julia J

2007-01-01

Three visual selective attention tasks were used to measure potential differences in susceptibility to interference and inhibitory cognitive control processes in 16 adolescents diagnosed with attention deficit hyperactivity disorder (ADHD) and 45 similar-aged controls. Susceptibility to interference was assessed using the Stroop color and word naming test. Efficiency of distractor inhibition was assessed in two conceptual negative priming tasks. The majority of studies in this area indicate that people with ADHD demonstrate higher levels of interference and lower negative priming effects in comparison with age-matched peers. However, we found that although the ADHD group was consistently slower to name target stimuli than the control group, there were no differences in interference or negative priming between the two groups.

Owing to the significant increase of mild motor delays and the strong intolerance of infants to be placed on prone position observed in the Physiotherapy Unit of the Maternal and Children's University Hospital of the Canaries (HUMIC), a study was conducted to determine whether positioning infants in the prone position while awake affected the achievement and quality of head control at three months. A prospective comparative practice-based study of a representative sample of 67 healthy infants born in the HUMIC, and divided into an experimental group (n = 35) and control group (n = 32). The Alberta Infant Motor Scale (AIMS) and a parent questionnaire were used as measurement tools. The intervention consisted of regular home visits to the experimental group (from the first to the third month). The two groups were evaluated in their homes at the end of 3 months. The differences in mean raw score of the AIMS at 3 months were, 16.26 in the experimental group and 10.38 in control group (P<.001). The percentile mean was 94 in the experimental group, and less than 50 (42) in the control group. All of the experimental group babies achieved the head control, with only 8 in the control group (25%). The significant findings suggest a direct relationship between the time spent in the prone position when the baby is awake and the achievement of head control at three months.

Remediation for Students With Mathematics Difficulties: An Intervention Study in Middle Schools.

PubMed

Moser Opitz, Elisabeth; Freesemann, Okka; Prediger, Susanne; Grob, Urs; Matull, Ina; Hußmann, Stephan

As empirical studies have consistently shown, low achievement in mathematics at the secondary level can often be traced to deficits in the understanding of certain basic arithmetic concepts taught in primary school. The present intervention study in middle schools evaluated whether such learning deficits can be reduced effectively and whether the type of instruction influences students' progress. The sample consisted of 123 students in 34 classes, split among one control group and two intervention groups: (a) small group instruction and (b) independent work partially integrated into regular classrooms. Over a period of 14 weeks, students were taught basic concepts, such as place value and basic operations. In addition, they practiced fact retrieval and counting (in groups). Multilevel regression analyses demonstrated that the interventions can be used to reduce given deficits.

Various forms of art therapy have been tested as adjuvants in the treatment of physical and emotional disorders, including music and poetry. To evaluate the effect of passive listening to music and poetry on the variation in pain, depression, and hope scores. This was a randomized trial, with multiple aspects and an allocation ratio of 1:1:1, in which one group listened to music, one group listened to poetry, and another group received no intervention over a period of three days. A total of 75 adult patients experiencing pain and hospitalized in a cancer facility were included. The study was conducted over a period of three months. The primary outcome consisted of pain evaluation using a Visual Analog Scale, and the secondary outcomes consisted of evaluations of depression (Beck Depression Inventory) and hope (Herth Hope Scale). The final sample consisted of 65 participants, with 22 in the music group, 22 in the poetry group, and 21 controls. Music promoted an improvement in pain (p < 0.001) and depression (p = 0.004), while poetry promoted an improvement in pain (p < 0.001), depression (p = 0.001), and hope (p = 0.009). However, a difference between the music and poetry groups and the control group after the study was only observed for the pain outcome (p < 0.001) (confidence interval = 95%). Both music and poetry produced a similar improvement in the pain intensity. The two therapies also affected depression scores, and only poetry increased hope scores. Further investigation of the effects and comparisons between the two therapies should be performed.

Effects of autoshaping procedures (Paired versus Random) and sipper fluid [chlordiazepoxide (CDP) versus water] on sipper-directed drinking were evaluated in 32 male Long-Evans rats maintained with free access to food and water. For the Paired/CDP group (n = 16), autoshaping procedures consisted of the presentation of the CDP sipper conditioned stimulus (CS) followed by the response-independent presentation of the food unconditioned stimulus (US). The concentration of CDP in the sipper CS (0.05, 0.10, 0.15, 0.20, and 0.25 mg/ml CDP) was increased across sessions. The Paired/Water group (n = 8) received only water in the sipper CS. The Random/CDP group (n = 8) received the CDP sipper CS and food US randomly with respect to one another. The Paired/CDP group drank significantly more of the 0.20 mg/ml and 0.25 mg/ml CDP solutions than the Random/CDP control, and more fluid than the Paired/Water control group when the sipper CS for the Paired/CDP group contained the three highest concentrations of CDP. CS-Only extinction procedures reliably reduced sipper CS-directed drinking in the Paired/CDP and the Paired/Water groups, but not in the Random/CDP group. Data are consistent with the hypothesis that Pavlovian autoshaping procedures induce sipper CS-directed drinking of CDP in rats deprived of neither food nor fluid. Implications for the autoshaping model of drug abuse are discussed.

Behavior management and reducing anxiety and pain are very important for success of treatment. Hence, apart from pharmacological management, such as conscious sedation, nonpharmacological interventions like music play a significant role. This study aims to evaluate the effects of music in reducing anxiety, pain, and behavior management. This study was conducted at the Department of Pedodontics in 2015. It consisted of 60 patients, age ranging from 3 to 7 years, who required dental treatment with local anesthesia. They were divided into three groups of 20 each. Group I consisted of upbeat music distraction group. Group II consisted of relaxing music distraction group. Group III consisted of control group. We scheduled the treatment in two visits. We used Venham picture test, North Carolina behavior rating scale, and visual analog scale test for the study. Baseline heart rate was also recorded. No significant differences were found among the three groups based on three scales used in the study. Management of child patient in dental clinic is a challenge for clinician. Apart from various pharmacological techniques, management of pediatric patients using audio music distraction has been introduced. However, music did not produce a reduction in pain, anxiety, or disruptive behavior. Various pharmacological techniques are present for the management of pediatric patients. Apart from it, there is need of introducing nonpharmacological techniques to reduce pain, anxiety, and to alter behavior of child. By this study, we have tried to evaluate the usefulness of music in child management.

Combined use of autogenic therapy and biofeedback in training effective control of heart rate by humans

NASA Technical Reports Server (NTRS)

Cowings, P. S.

1977-01-01

Experiments were performed on 24 men and women (aged 20-27 yr) in three equal groups who were taught to control their own heart rates by autogenic training and biofeedback under dark and sound-isolated conditions. Group I was parasympathetic dominant, group II was sympathetic dominant, and group III consisted of parasympathetic-dominant subjects and controls who received only biofeedback of their own heart rates. The results corroborate three hypotheses: (1) subjects with para-sympathetic-dominant autonomic profiles perform in a way that is both qualitatively and quantitatively different from subjects with sympathetic-dominant autonomic profiles; (2) tests of interindividual variability yield data relevant to individual performance in visceral learning tasks; and (3) the combined use of autogenic training, biofeedback, and verbal feedback is suitable for conditioning large stable autonomic responses in humans.

Improving Managers' Psychophysical Well-Being: Effectiveness of Respiratory Sinus Arrhythmia Biofeedback.

Munafò, Marianna; Patron, Elisabetta; Palomba, Daniela

2016-06-01

High work stress has been consistently associated with disturbed autonomic balance, specifically, lowered vagal cardiac control and increased sympathetic activity, which may lead to increased cardiovascular risk. Stress management procedures have been proposed to reduce autonomic dysfunctions related to work stress in different categories of workers exposed to heightened work demands, while a limited number of studies addressed this issue in managers. The present study was aimed at evaluating the effectiveness of a respiratory sinus arrhythmia (RSA) biofeedback (BF) intervention on psychological and physiological outcomes, in managers with high-level work responsibilities. Thirty-one managers leading outstanding private or public companies were randomly assigned to either a RSA-BF training (RSA-BF; N = 16) or a control group (N = 15). The RSA-BF training consisted of five weekly 45 min sessions, designed to increase RSA, whereas controls had to provide a daily stress diary once a week. After the training, managers in both groups reported reduced heart rate at rest, lower anxiety levels and improvement in health-related quality of life. More importantly, managers in the RSA-BF group showed increased vagal control (as indexed by increased RSA), decreased sympathetic arousal (as indexed by reduced skin conductance and systolic blood pressure) and lower emotional interferences, compared to managers in the control group. Results from this study showed that RSA-BF training was effective in improving cardiac autonomic balance at rest. Moreover, findings from this study underline the effectiveness of biofeedback in reducing psychophysiological negative outcomes associated with stress in managers.

The aim of the present study was to assess the feasibility of using mandibular CBCT radiomorphometric indices and box-counting fractal dimension (FD) to detect osteoporosis in post-menopausal females, compare them with the healthy control group and to correlate the findings with the bone mineral density measured by dual X-ray absorptiometry (DXA). This study consisted of 50 post-menopausal females, with age ranging from 55 to 70 years. Based on their DXA results, they were classified into osteoporotic and control groups. Mandibular CBCT radiomorphomertic indices and FD analysis were measured. Significant differences were found for the CT cortical index scores (CTCI), CT mental index (CTMI) and CT mandibular index (CTI) between the control and osteoporotic groups. The control group showed higher mean values than the osteoporotic group. For FD values, no significant differences were found between the two groups. CBCT radiomorphometric indices could be used as an adjuvant tool to refer patients at risk of osteoporosis for further assessment.

This study was conducted to develop and test the effects of a motivational interviewing self-management program for use with elderly patients with diabetes mellitus. A non-equivalent control group pretest-posttest design was used. The participants were 42 elderly diabetic patients (experimental group: 21, control group: 21). The motivational interviewing self-management program for elders with diabetes mellitus developed in this study consisted of a 12-week program in total (8 weeks for group motivational interviewing and education and 4 weeks for individual motivational interviewing on the phone). Data were collected between February 13 and May 3, 2013 and were analyzed using t-test, paired t-test, and repeated measure ANOVA with SPSS/WIN 18.0. For the experimental group, significant improvement was found for self-efficacy, self-care behavior, glycemic control and quality of life (daily life satisfaction, influence of disease) as compared to the control group. The study findings indicate that the motivational interviewing self-management program is effective and can be recommended as a nursing intervention for elderly patients with diabetes mellitus.

Previous studies have shown that mindfulness meditation may improve well-being in healthy individuals and be effective in the treatment of mental and neurological disorders. Here, we investigated the effects of an 8-week mindfulness-mediation program on the personality profiles of three groups of healthy individuals with no previous experience with meditation as compared to a control group not enrolled in any training. Personality profiles were obtained through the Temperament and Character Inventory (Cloninger et al., 1993). In the experimental groups, significant increments after the training were obtained in all the three character scales describing the levels of self maturity at the intrapersonal (Self-Directedness), interpersonal (Cooperativeness), and transpersonal (Self-Transcendence) levels. No changes were found in the control group. Strikingly, these effects were significant only in those groups who were engaged in consistent daily meditation practice but not in the group who attended the meditation training but were less consistent in home practice. Since higher scores in the character scales are associated to a lower risk of personality disorder, we propose that the increase of self maturity after the training may be an important mechanism for the effectiveness of mindfulness-oriented meditation in psychotherapeutic contexts.

Peritonitis, which is one of the leading complications of peritoneal dialysis (PD) worldwide, severely affected morbidity and mortality of the PD patients. Although many efforts have been made to prevent PD-related peritonitis, it seems impossible to prevent it completely. Many causes have been reported to lead to peritonitis, and contamination during bag exchange is one of the important risk factors for peritonitis. Here, we introduce an operating vehicle, which we invented to provide a sterile and safe space for bag exchange. A single-center, retrospective, case-control study was undertaken to determine whether this operating vehicle has a protective role in preventing peritonitis. In total, 462 continuous ambulatory peritoneal dialysis patients were included in this study from October 2014 to March 2017. According to their personal will, these patients chose to use operating vehicle or traditional method during their bag exchange. The demographic, clinical and laboratory data of these patients in the two groups were collected, analyzed and compared. Of 462 patients with home dialysis, operating vehicle group consisted of 61 patients, and control group consisted of 401 patients. In the control group, over 677 patient-years, peritonitis occurred in 69 of 401 patients (17.2%), while in the operating vehicle group, over 60 patient-years, only 4 of 61 patients (6.6%) had episodes of peritonitis. The number of patients suffered from peritonitis was significantly decreased in the operating vehicle group (P = 0.034). Besides, there were a total of 99 episodes of peritonitis, and the rate was 1 episode every 7.2 patient-years in control group and 1 episode every 12 patient-years in the operating vehicle group. There was significant difference between the two groups (0.013). Positive dialysate cultures were obtained in majority of the peritonitis episodes (60.6%). Operating vehicle might help to reduce PD-related peritonitis by preventing contamination during bag exchange. Further studies are still needed to demonstrate the protective role of the operating vehicle in preventing peritonitis.

We aimed to investigate whether agoraphobia (A) in panic disorder (PD) has any effects on oxidative and anti-oxidative parameters. We measured total antioxidant capacity (TAC), paraoxonase (PON), arylesterase (ARE) antioxidant and malondialdehyde (MDA) oxidant levels using blood samples from a total of 31 PD patients with A, 22 PD patients without A and 53 control group subjects. There was a significant difference between the TAC, PON, ARE and MDA levels of the three groups consisting of PD with A, PD without A and the control group. The two-way comparison to clarify the group creating the difference showed that the TAC, PON, and ARE antioxidants were significantly lower in the PD with A group compared to the control group while the MDA oxidant was significantly higher. There was no significant difference between the PD without A and control groups for TAC, PON, ARE and MDA levels. We clearly demonstrated that the oxidative stress and damage to the anti-oxidative mechanism are significantly higher in the PD group with A. These findings suggest that oxidative/anti-oxidative mechanisms may play a more important role on the pathogenesis of PB with A. PMID:24474979

To explore articulatory kinematic differences between normal and dysarthric speakers post-traumatic brain injury (TBI) during syllable and sentence productions. A comparison between the control, mild (MTBI) and severe TBI groups for all measured kinematic parameters was carried out using the Kruskal Wallis test. Ten participants with a severe TBI and six post-MTBI formed the experimental group. The control group consisted of 14 age and sex matched non-neurologically impaired speakers. Articulatory kinematic profiles for the three groups were obtained using the Electromagnetic Articulograph (EMA) while repeating sentence and syllable embedded /t/ and /k/ productions at a habitual rate and loudness level. Significant differences between the severe TBI and control group were identified only for the release phase of the /t/ sentence productions wherein an increase in mean maximum acceleration was observed for the severe TBI group. While a simple syllable repetition task at a moderate rate was unable to differentiate the three groups, a complex sentence production task precipitated an increase in mean maximum acceleration which may be indicative of increased articulatory effort and impaired speech motor control even at a convenient rate for the severe group.

This study investigated the effects of cocoa butter and sunflower oil alone and in combination on performance, some biochemical parameters, immunoglobulin, and antioxidant vitamin status in Wistar rats. Forty-eight male rats were assigned to four groups, consisting of 12 rats with 3 replicates. Control received balanced rat diet without oil, cocoa butter group received 3.5% cocoa butter, sunflower oil group received 3.5% sunflower oil, the last group received 1.75% sunflower oil + 1.75% cocoa butter supplementation in the rat diet for 8 weeks. The total feed consumption in sunflower oil group was statistically lower than in the other groups. The serum creatinine level was decreased in cocoa butter group compared to control. Triglyceride and VLDL cholesterol levels were decreased in only sunflower oil and only cocoa butter groups as compared to control. The level of Ig M was statistically lower in cocoa butter and cocoa butter + sunflower oil groups than in control and sunflower oil groups. There were no statistically important difference in vitamin concentrations among trial groups. It was concluded that the supplementation of cocoa butter in diet decreased Ig M level, while the supplementation of cocoa butter and sunflower oil alone decreased the triglyceride and VLDL cholesterol levels.

Although the amygdala has been repeatedly implicated in normal primate social behavior, great variability exists in the specific social and nonsocial behavioral changes observed after bilateral amygdala lesions in nonhuman primates. One plausible explanation pertains to differences in social context. To investigate this idea, we measured the social behavior of amygdala-lesioned and unoperated rhesus monkeys (Macaca mulatta) in two contexts. Animals interacted in four-member social groups over 32 test days. These animals were previously assessed in pairs (Emery et al., 2001), and were, therefore, familiar with each other at the beginning of this study. Across the two contexts, amygdala lesions produced a highly consistent pattern of social behavior. Operated animals engaged in more affiliative social interactions with control group partners than did control animals. In the course of their interactions, amygdala-lesioned animals also displayed an earlier decrease in nervous and fearful personality qualities than controls. The increased exploration and sexual behavior recorded for amygdala-lesioned animals in pairs was not found in the four-member groups. We conclude that the amygdala contributes to social inhibition and this function transcends various social contexts. PMID:18410164

The study of animal personality, defined as consistent inter-individual differences in correlated behavioral traits stable throughout time and/or contexts, has recently become one of the fastest growing areas in animal biology, with study species ranging from insects to non-human primates. The latter have, however, only occasionally been tested with standardized experiments. Instead their personality has usually been assessed using questionnaires. Therefore, this study aimed to test 21 common marmosets (Callithrix jacchus) living in three family groups, in five different experiments, and their corresponding controls. We found that behavioral differences between our animals were not only consistent over time, but also across different contexts. Moreover, the consistent behaviors formed a construct of four major non-social personality components: Boldness-Shyness in Foraging, Boldness-Shyness in Predation, Stress-Activity, and Exploration-Avoidance. We found no sex or age differences in these components, but our results did reveal differences in Exploration-Avoidance between the three family groups. As social environment can have a large influence on behavior of individuals, our results may suggest group-level similarity in personality (i.e., "group personality") in common marmosets, a species living in highly cohesive social groups.

Outcomes of long-term outpatient tinnitus-coping therapy: psychometric changes and value of tinnitus-control instruments.

Caffier, Philipp P; Haupt, Heidemarie; Scherer, Hans; Mazurek, Birgit

2006-12-01

Increasing tinnitus compliance and coping are desirable aims of successful treatment in chronic tinnitus. However, application of established procedures such as tinnitus retraining therapy (TRT) is often relatively short. In addition, the value of tinnitus control instruments (TCI) is questionable, especially for minor severity levels of tinnitus, and the comparability of treatment results is low. To evaluate long-term changes of tinnitus-related distress, defined psychometric data were collected in patients with compensated tinnitus (cT) or decompensated tinnitus (dT) during a standardized 2-yr outpatient tinnitus-coping therapy (TCT). In a prospective clinical investigation, the data of 70 tinnitus patients were recorded at the beginning and at 6-mo intervals, with a final investigation after 24 mo. The first group consisted of 40 patients with cT and dT who were randomly assigned to a treatment group and a waiting-list control group. After a period of 12 mo without treatment, the control group was treated similarly. The tinnitus questionnaire (TQ) of Goebel and Hiller, visual analog scales (VAS), and a severity questionnaire for tinnitus-associated complaints were used as psychodiagnostic instruments. Therapy components consisted of counseling, fitting patients with TCIs (TCI provision), auditory and relaxation training, and psychosomatic care if necessary. A second group of 30 patients with cT receiving TCT without TCI devices was investigated to evaluate the additive efficacy of TCI in cT. The initial TQ score did not differ between the treatment group and the waiting-list control group. After 12 mo, the control group did not show any significant changes, but the treatment group had improved significantly. During TCT, the combined data of both groups showed a statistically significant decrease of the TQ score in dT (59.1 to 34.8) and cT (32.8 to 24.0). These changes were especially reflected by the subscales of cognitive and emotional distress and also by the VAS and the severity questionnaire. dT patients benefitted without dependence on age or duration of pre-existing tinnitus; for cT patients, this was true mainly of the younger and older subjects and for tinnitus lasting for less than 1 yr. TCI provision improved the efficacy of TCT in patients with cT. The psychometric changes demonstrate a clear decrease of tinnitus-related distress in all severity levels of sufficiently treated chronic tinnitus. Long-term TCT induces improvement even up to the time of 24 mo. With TCIs established particularly in patients with dT, our results suggest that a supporting adjustment of TCI devices is helpful in cT to foster quicker rehabilitation. The outpatient interdisciplinary TCT, consisting of cognitive tinnitus desensitization, TCI provision, and psychosomatic support if required, represents a successful treatment strategy for both dT and cT patients.

2008-01-01

Objectives. We tested the efficacy of a combined pharmacologic and behavioral smoking cessation intervention among women in a state prison in the southern United States. Methods. The study design was a randomized controlled trial with a 6-month waitlist control group. The intervention was a 10-week group intervention combined with nicotine replacement therapy. Two hundred and fifty participants received the intervention, and 289 were in the control group. Assessments occurred at baseline; end of treatment; 3, 6, and 12 months after treatment; and at weekly sessions for participants in the intervention group. Results. The intervention was efficacious compared with the waitlist control group. Point prevalence quit rates for the intervention group were 18% at end of treatment, 17% at 3-month follow-up, 14% at 6-month follow-up, and 12% at 12-month follow-up, quit rates that are consistent with outcomes from community smoking-cessation interventions. Conclusions. Female prisoners are interested in smoking cessation interventions and achieved point-prevalence quit rates similar to community samples. Augmenting tobacco control policies in prison with smoking cessation interventions has the potential to address a significant public health need. PMID:18703440

Neonatal jaundice is a common condition that occurs in newborn infants in the first week of life. Today, techniques used for detection are required blood samples and other clinical testing with special equipment. The aim of this study is creating a non-invasive system to control and to detect the jaundice periodically and helping doctors for early diagnosis. In this work, first, a patient group which is consisted from jaundiced babies and a control group which is consisted from healthy babies are prepared, then between 24 and 48 h after birth, 40 jaundiced and 40 healthy newborns are chosen. Second, advanced image processing techniques are used on the images which are taken with a standard smartphone and the color calibration card. Segmentation, pixel similarity and white balancing methods are used as image processing techniques and RGB values and pixels' important information are obtained exactly. Third, during feature extraction stage, with using colormap transformations and feature calculation, comparisons are done in RGB plane between color change values and the 8-color calibration card which is specially designed. Finally, in the bilirubin level estimation stage, kNN and SVR machine learning regressions are used on the dataset which are obtained from feature extraction. At the end of the process, when the control group is based on for comparisons, jaundice is succesfully detected for 40 jaundiced infants and the success rate is 85 %. Obtained bilirubin estimation results are consisted with bilirubin results which are obtained from the standard blood test and the compliance rate is 85 %.

The purposes of this study were to: (a) develop a comprehensive communication course combined with a group program for improving communication skills; and (b) examine the effects of the comprehensive communication course on interpersonal communication, relationship change, self-esteem, and depression in nursing students. The experimental group consisted of 82 nursing students, and the control group, 108 nursing students. Both groups each took communication courses from March to June, 2002 and 2003. A group program for improving communication skills was conducted for each 8 subgroups of the experimental group for 90 minutes once a week during the 6 weeks, while the existing communication lecture was conducted for the control group. Both groups were post-tested after the intervention for verifying the difference of variables between the two groups, and the experimental group was also pre-tested for verifying the difference between before and after the treatment. Interpersonal communication score of the post-test in the experimental group was significantly higher than in the control group and the depression score of the post-test in the experimental group was significantly lower than in the control group. Interpersonal communication, relationship change and self-esteem scores were significantly increased and the depression score was significantly decreased in experimental group after the treatment. In conclusion, the comprehensive communication course that was developed in this study had positive effects on communication skills in nursing students.

We discuss the analytic and practical considerations in a large case-control study that had two control groups; the first control group consisting of partners of patients and the second obtained by random digit dialling (RDD). As an example of the evaluation of a general lifestyle factor, we present body mass index (BMI). Both control groups had lower BMIs than the patients. The distribution in the partner controls was closer to that of the patients, likely due to similar lifestyles. A statistical approach was used to pool the results of both analyses, wherein partners were analyzed with a matched analysis, while RDDs were analyzed without matching. Even with a matched analysis, the odds ratio with partner controls remained closer to unity than with RDD controls, which is probably due to unmeasured confounders in the comparison with the random controls as well as intermediary factors. However, when studying injuries as a risk factor, the odds ratio remained higher with partner control subjects than with RRD control subjects, even after taking the matching into account. Finally we used factor V Leiden as an example of a genetic risk factor. The frequencies of factor V Leiden were identical in both control groups, indicating that for the analyses of this genetic risk factor the two control groups could be combined in a single unmatched analysis. In conclusion, the effect measures with the two control groups were in the same direction, and of the same order of magnitude. Moreover, it was not always the same control group that produced the higher or lower estimates, and a matched analysis did not remedy the differences. Our experience with the intricacies of dealing with two control groups may be useful to others when thinking about an optimal research design or the best statistical approach.

In our previous study, we used composite grafts consisting of meshed porcine acellular dermal matrix (PADM) and thin split-thickness autologous epidermis to cover full thickness burn wounds in clinical practice. However, a certain degree of contraction might occur because the distribution of dermal matrix was not uniform in burn wound. In this study, we prepare a composite skin graft consisting of PADM with the aid of laser to improve the quality of healing of burn wound. PADM was prepared by the trypsin/Triton X-100 method. Micropores were produced on the PADM with a laser punch. The distance between micropores varied from 0.8, 1.0, 1.2 to 1.5mm. Full thickness defect wounds were created on the back of 144 SD rats. The rats were randomly divided into six groups: micropore groups I-IV in which the wound were grafted with PADM with micropores, in four different distances, respectively and split-thickness autograft; mesh group rats received meshed PADM graft and split-thickness autograft; control group received simple split-thickness autografting. The status of wound healing was histologically observed at regular time points after surgery. The wound healing rate and contraction rate were calculated. The wound healing rate in micropore groups I and II was not statistically different from that in control group, but was significantly higher than that in mesh group 6 weeks after grafting. The wound healing rate in micropore groups III and IV was lower than that in mesh and control groups 4 and 6 weeks after grafting. The wound contraction rate in micropore groups I and II was remarkably lower than that in control group 4 and 6 weeks after surgery and it was significantly much lower than that in mesh group 6 weeks after surgery. Histological examination revealed good epithelization, regularly arranged collagenous fibers and integral structure of basement membrane. Laser micropore PADM (0.8 or 1.0mm in distance) grafting in combination with split-thickness autografting can improve wound healing. The PADM with laser micropores in 1.0mm distance is the better choice.

Purpose Total knee arthroplasty (TKA) accompanies the risk of bleeding and need for transfusion. There are several methods to reduce postoperative blood loss and blood transfusion. One such method is using tranexamic acid during TKA. The purpose of this study was to confirm whether tranexamic acid reduces postoperative blood loss and blood transfusion after TKA. Materials and Methods A total of 100 TKA patients were included in the study. The tranexamic acid group consisted of 50 patients who received an intravenous injection of tranexamic acid. The control included 50 patients who received a placebo injection. The amounts of drainage, postoperative hemoglobin, and transfusion were compared between the groups. Results The mean amount of drainage was lower in the tranexamic acid group (580.6±355.0 mL) than the control group (886.0±375.5 mL). There was a reduction in the transfusion rate in the tranexamic acid group (48%) compared with the control group (64%). The hemoglobin level was higher in the tranexamic acid group than in the control group at 24 hours postoperatively. The mean units of transfusion were smaller in the tranexamic acid group (0.76 units) than in the control group (1.28 units). Conclusions Our data suggest that intravenous injection of tranexamic acid decreases the total blood loss and transfusion after TKA. PMID:27595071

Associations between tongue movement pattern consistency and formant movement pattern consistency in response to speech behavioral modificationsa)

Mefferd, Antje S.

2016-01-01

The degree of speech movement pattern consistency can provide information about speech motor control. Although tongue motor control is particularly important because of the tongue's primary contribution to the speech acoustic signal, capturing tongue movements during speech remains difficult and costly. This study sought to determine if formant movements could be used to estimate tongue movement pattern consistency indirectly. Two age groups (seven young adults and seven older adults) and six speech conditions (typical, slow, loud, clear, fast, bite block speech) were selected to elicit an age- and task-dependent performance range in tongue movement pattern consistency. Kinematic and acoustic spatiotemporal indexes (STI) were calculated based on sentence-length tongue movement and formant movement signals, respectively. Kinematic and acoustic STI values showed strong associations across talkers and moderate to strong associations for each talker across speech tasks; although, in cases where task-related tongue motor performance changes were relatively small, the acoustic STI values were poorly associated with kinematic STI values. These findings suggest that, depending on the sensitivity needs, formant movement pattern consistency could be used in lieu of direct kinematic analysis to indirectly examine speech motor control.

Despite the important role that health professionals have in reducing tobacco use, many have a smoking habit themselves. The prevalence of smoking is particularly high among nurses. To test the efficacy, acceptability and feasibility of a motivational interviewing (MI) based smoking cessation intervention with nurses. Two group parallel experimental design with random allocation to groups. A large teaching hospital in the North of Spain. Nurses who smoked (n=30) were randomised into two groups: motivational interviewing based intervention (n=15) and usual care (n=15). Motivational interviewing based intervention consisted of four individual MI sessions. Usual care consisted of brief advice. Variables considered to assess efficacy were biochemically verified smoking cessation, mean cigarettes smoked, stages of change, self-efficacy and depression score. Variables to assess acceptability and feasibility included participant satisfaction, adherence to MI, and duration of sessions. Data were collected at: baseline, end of intervention and three months after the end of the intervention. At three month follow up, compared with the control group, more nurses in the intervention group had quit (absolute difference 33.3%; 95% confidence interval [CI] 2.6-58.2). In the nurses who did not quit, there was no significant difference between the intervention and control groups in the number of cigarettes smoked per day, although progress in the stages of change was greater in the intervention group compared to the control group. Measures of acceptability and feasibility indicated good satisfaction with the intervention, with high levels of attendance and completion. This study found a beneficial effect of motivational interviewing on nurses' smoking cessation. The intervention was acceptable for nurses and a number of aspects were identified that need to be considered prior to conducting a larger scale in order to optimise the intervention. Using MI might be a novel approach to the problem of health professionals who smoke. Copyright © 2013 Elsevier Ltd. All rights reserved.

Cruciferous vegetable intake is inversely associated with lung cancer risk among smokers: a case-control study

PubMed Central

2010-01-01

Background Inverse associations between cruciferous vegetable intake and lung cancer risk have been consistently reported. However, associations within smoking status subgroups have not been consistently addressed. Methods We conducted a hospital-based case-control study with lung cancer cases and controls matched on smoking status, and further adjusted for smoking status, duration, and intensity in the multivariate models. A total of 948 cases and 1743 controls were included in the analysis. Results Inverse linear trends were observed between intake of fruits, total vegetables, and cruciferous vegetables and risk of lung cancer (ORs ranged from 0.53-0.70, with P for trend < 0.05). Interestingly, significant associations were observed for intake of fruits and total vegetables with lung cancer among never smokers. Conversely, significant inverse associations with cruciferous vegetable intake were observed primarily among smokers, in particular former smokers, although significant interactions were not detected between smoking and intake of any food group. Of four lung cancer histological subtypes, significant inverse associations were observed primarily among patients with squamous or small cell carcinoma - the two subtypes more strongly associated with heavy smoking. Conclusions Our findings are consistent with the smoking-related carcinogen-modulating effect of isothiocyanates, a group of phytochemicals uniquely present in cruciferous vegetables. Our data support consumption of a diet rich in cruciferous vegetables may reduce the risk of lung cancer among smokers. PMID:20423504

To investigate vitamin D status in children with Hashimoto thyroiditis. The study group consisted of 78 children recently diagnosed as Hashimoto thyroiditis and 74 subjects as the control group. Parameters of calcium metabolism, thyroid function tests, and 25-hydroxyvitamin D [25(OH)D] levels were measured. Vitamin D deficiency rate was significantly higher in the Hashimoto group compared with the control subjects (73.1% vs. 17.6%, p < 0.0001). In the Hashimoto group, mean 25(OH)D levels were significantly lower compared with the control group (31.2 +/- 11.5 versus 57.9 +/- 19.7 nmol/L, p < 0.001) and was inversely correlated with the anti-thyroid peroxidase (anti-TPO) levels (r = -0.30, p = 0.007). The higher vitamin D deficiency rates besides lower vitamin D levels in the Hashimoto group together with the inverse correlation between vitamin D and anti-TPO suggest that vitamin D deficiency may have a role in the autoimmune process in Hashimoto thyroiditis in children.

2006-12-01

This study investigated the effect of conceptual change text-oriented instruction over traditional instruction on students' understanding of solution concepts (e.g., dissolving, solubility, factors affecting solubility, concentrations of solutions, types of solutions, physical properties of solutions) and their attitudes towards chemistry. The sample of this study consisted of 87 undergraduate students from two classes enrolled in an introductory chemistry course. One of the classes was assigned randomly to the control group, and the other class were assigned randomly to the experimental group. During teaching the topic of solution concepts in the chemistry curriculum, a conceptual change text-oriented instruction was applied in the experimental group whereas traditional instruction was followed in the control group. The results showed that the students in the experimental group performed better with respect to solution concepts. In addition, it has been found that there was no significant difference between the attitudes of students in the experimental and control groups towards chemistry.

Most studies on conduct disorder (CD) have focused on male adolescents, disregarding analysis of this psychopathology in women. The purpose of this study was to identify differences in empathy and theory of mind (ToM) in a group of adolescent women with CD and a control group. Thirty-six adolescent women were selected from an initial sample of 239 adolescents (CD group = 18, control group = 18). Empathy and ToM were evaluated through objective instruments. Mean comparisons and multivariate analysis were performed to ascertain differences between cases and controls and to propose a prediction model based on clinical status. Significant differences in empathic abilities and ToM were found between the groups. The model that differentiated both groups was composed of eye-reading ability, perspective taking, and personal distress. These findings are consistent with previous studies. Capacity to take the other's perspective and the recognition of emotions in the face are protective factors against CD in women.

Ultrasonographic assessment of the thyroid gland structure in inflammatory bowel disease patients.

Neubauer, Katarzyna; Woźniak-Stolarska, Barbara

2012-01-01

The etiopathogenesis of inflammatory bowel disease (IBD), encompassing Crohn's disease (CD) and ulcerative colitis (UC), is still not fully elucidated and seems to be multifactorial. It has been suggested that genetic, immunological and environmental factors participate in IBD development. IBD extraintestinal manifestations include rheumatic, metabolic, dermatologic, ophthalmologic, hepatobiliary, pancreatic, urologic, pulmonary, neurological, hematological and thromboembolic complications. Thyroid gland diseases have not been confirmed as extraintestinal manifestations of IBD. However, it is known that some thyroid diseases share an immunological background with IBD, and that dysfunction of the thyroid gland may induce gastrointestinal symptoms. Ultrasound examination is the gold standard for evaluation of thyroid gland morphology. This study was designed to assess the prevalence of abnormalities in the structure of the thyroid gland in IBD patients and to compare it to the control group. The study group consisted of 199 consecutive IBD patients (80 CD patients and 119 UC patients) hospitalized at the Department of Gastroenterology and Hepatology of Wroclaw Medical University (Poland). The control group consisted of 42 healthy volunteers and patients with functional gastrointestinal disorders. The most common finding in the ultrasound examination in IBD patients were tumors. Tumors, which were smaller than or equal to 10 mm were present in 11.5% of IBD patients; and tumors larger than 10 mm were present in 13.1%. These results show that small tumors (less than 10 mm in diameter) of the thyroid gland are more frequent among patients with CD and UC compared to the control group (p = 0.0001 and p = 0.001, respectively). Additionally, enlargement of the thyroid gland occurs more often in UC patients compared to the control group (p = 0.003). There was no difference in the frequency of thyroid abnormalities between UC and CD patients. In patients with inflammatory bowel diseases focal lesions relating to tumors of the thyroid gland are more common than in the control group. In patients with ulcerative colitis enlargement of the thyroid gland is more frequent than in the control group. Initial assessments of IBD patients should include ultrasound examinations of the thyroid gland.

investigate impulsivity levels and inhibitory control in women crack users and explore the relationships between impulsivity and inhibitory control. 52 healthy women (M = 32.83 years; SD = 9.54) and 46 crack cocaine users (M = 31.02 years; SD = 7.73), in abstinence, performed the assessment protocol included a Sociodemographic Data Questionnaire, Mini-Mental State Examination (MMSE), a GO/No-Go Task and the Barratt Impulsiveness Scale-11 (BIS-11). It was a quantitative research with cross-sectional design and control group. crack group showed higher levels of impulsivity in all domains when compared to the control group (crack group M = 76.39, SD = 11.39, control group M = 58.53, SD = 10.76, p <.01). Participants from the crack group presented a significantly higher total reaction time in the Go-NoGo task (F(1,93) = 9.93, p =.002; effect size =.09, observed power =.87) and significantly more commission (F(1,93) = 7.20, p =.009; effect size =.07, observed power =.75) and omission errors (F(1,93) = 6.04, p =.01; effect size =.06, observed power =.68), in Go/NoGo Task. Groups did also significantly differ on total standard deviations suggesting that variability in total reaction time was significantly greater in the crack group. Results showed that only in the crack group there were significant correlations between Go-NoGo parameters and Barratt Impulsiveness Scale. Our findings are consistent that impulsivity and inhibitory control are closely linked to crack use in women. Future studies should consider to evaluate crack users in different withdrawal times, controlling the impact of abstinence time in the variables studied.

To identify clinical predictors of heteroaggressive behavior. Three hundreds and three women serving sentence in a penal colony were examined using clinical, neurologic and statistical methods. The main group consisted of 225 women with heteroaggressive behavior, the control group included 78 women without aggressive behavior. Differences between the main and control groups in the structure of mental disorders and key syndromes were revealed. The authors conclude that the states with elements of dysphoria, dysthymia, decompensation of personality disorders, which are defined in the various forms of mental pathology, are the most significant predictors of heteroaggressive behavior in women in the penal colony.

The aim of this study was to determine the effects of low-level laser therapy (LLLT) on wound healing at free gingival graft (FGG) donor sites. Forty patients requiring FGG were selected for this randomized, controlled, and double-blinded prospective clinical trial. The FGG donor sites were treated with LLLT and compared with an untreated control group. The Wound-Healing Index (WHI), tissue consistency, color match, and H 2 O 2 bubbling test for the evaluation of complete wound epithelialization were recorded on the 3rd, 7th, 14th and 21st days. The pain-burning level, number of analgesics, and bleeding were recorded for 7 days. Donor area soft tissue thickness (TT) was measured at baseline and at the first month. The prevalence of Complete Wound Epithelization was higher in the LLLT group than in the control group on the 14th day (p < 0.001). The bleeding was lower in the test group than in the control group during the first 2 days (p ≤ 0.001). Higher WHI Scores were observed in the test group relative to the control group at all visits (p ≤ 0.001). Color match scores were higher in the test group than in the control group at the first 3 visits (p < 0.05). The TT changed from 4.62 ± 0.79 to 4.71 ± 0.82 mm in the LLLT group and from 4.23 ± 0.62 to 4.01 ± 0.68 mm in the control group. It can be concluded that LLLT enhances FGG donor site wound healing and preserves TT at palatinal donor sites.

The aim of the current study was to evaluate the effect of pelvic floor muscle training in men with poststroke lower urinary tract symptoms. Thirty-one poststroke men, median age 68 years, were included in this single-blinded randomized controlled trial. Thirty participants, 15 in each group, completed the study. The intervention consisted of 3 months (12 weekly sessions) of pelvic floor muscle training in groups and home exercises. The effect was evaluated by the DAN-PSS-1 (Danish Prostate Symptom Score) questionnaire, a voiding diary, and digital anal palpation of the pelvic floor muscle. The DAN-PSS-1, symptom score indicated a statistical significant improvement ( p < .01) in the treatment group from pretest to posttest, but not in the control group. The DAN-PSS-1, total score improved statistically significantly in both groups from pretest to posttest (treatment group: p < .01; control group: p = .03). The median voiding frequency per 24 hours decreased from 11 at pretest to 7 (36%; p = .04) at posttest and to 8 (27%; p = .02) at follow-up in treatment group, although not statistical significantly more than the control group. The treatment group but not the control group improved statistically significantly in pelvic floor muscle function ( p < .01) and strength ( p < .01) from pretest to posttest and from pretest to follow-up ( p = .03; p < .01). Compared with the control group the pretest to posttest was significantly better in the treatment group ( p = .03). The results indicate that pelvic floor muscle training has an effect for lower urinary tract symptoms, although statistical significance was only seen for pelvic floor muscle.

Study Objectives: To investigate cost-effectiveness of adolescent cognitive behavioral therapy for insomnia (CBTI) in group- and Internet-delivered formats, from a societal perspective with a time horizon of 1 y Methods: Costs and effects data up to 1-y follow-up were obtained from a randomized controlled trial (RCT) comparing Internet CBTI to face-to-face group CBTI. The study was conducted at the laboratory of the Research Institute of Child Development and Education at the University of Amsterdam, and the academic youth mental health care center UvAMinds in Amsterdam. Sixty-two participants meeting Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision criteria for insomnia were randomized to face-to-face group CBTI (GT; n = 31, age = 15.6 y ± 1.8, 71.0% girls) or individual Internet CBTI (IT; n = 31, age = 15.4 y ± 1.5, 83.9% girls). The intervention consisted of six weekly sessions and a 2-mo follow up booster-session of CBTI, consisting of psychoeducation, sleep hygiene, restriction of time in bed, stimulus control, cognitive therapy, and relaxation techniques. GT sessions were held in groups of six to eight adolescents guided by two trained sleep therapists. IT consisted of individual Internet therapy with preprogrammed content similar to GT, and guided by trained sleep therapists. Results: Outcome measures were subjective sleep efficiency (SE) ≥ 85%, and quality-adjusted life-years (QALY). Analyses were conducted from a societal perspective. Incremental cost-effectiveness ratios (ICERs) were calculated using bootstrap sampling, and presented in cost-effectiveness planes. Primary analysis showed costs over 1 y were higher for GT but effects were similar for IT and GT. Bootstrapped ICERs demonstrated there is a high probability of IT being cost-effective compared to GT. Secondary analyses confirmed robustness of results. Conclusions: Internet CBTI is a cost-effective treatment compared to group CBTI for adolescents, although effects were largely similar for both formats. Further studies in a clinical setting are warranted.

The aim of this study was to determine the effects of nutritional education and vigorous physical activity on health-related parameters. The sample group consisted of 134 children from 5 rurally located schools. Participants were divided between 5 different experimental groups: control group (CG), physical activity group (PA), nutritional education group (NE), combined intervention group (PA+NE), and a combined intervention group with additional substitution of normally used oil for extra virgin olive oil (EVOO; PA+NE+EVOO). The intervention consisted of 60 minute sessions of physical activity held twice a week as well as nutritional education sessions held over 6 months. Students in the groups receiving physical activity reduced their fat percentage and increased their muscle mass post intervention. At posttest the lipid profile improved in all intervention groups. The proportion of macronutrients and dietary cholesterol improved in the groups receiving nutritional education. The posttest comparison showed significantly lower fat percentage, sum of skinfolds and waist circumference in NE relative to CG and PA relative to CG. Diastolic blood pressure and glycaemia were significantly lower in PA+NE+EVOO relative to CG. A school-based program consisting of nutritional education or nutritional education plus a physical activity program showed a positive effect on health-related parameters in children.

To assess the impact of a nutrition education program for teachers in the nutritional status, food knowledge and food consumption of their pre basic and basic students, and in the controls. A nutrition education intervention was conducted in pre basic and basic teachers in a school year, with a pre-post evaluation of their students, compared with a control group. Subjects were 817 students (389 men and 428 women) from pre kindergarten to the second grade. The 465 students of the intervened group were distributed in two schools (Liceo 1 = 283; Liceo 2 = 182) and 352 in the control school. The nutrition intervention consisted in 9 interactive workshops for teachers with the utilization of Information and Communication Technologies (ICT). The pre post evaluation consisted in a nutritional status assessment, and a food and nutrition survey with questions related with food knowledge and food consumption, at the beginning and at the end of the school year. There were no significant differences in nutritional status between the beginning and the end of the intervention. In one of the experimental schools (Liceo 2) there was a significant decrease in obesity, in women and in the age-group 7-9 years. In the experimental group there was a significant improvement in food knowledge and a decrease in non-healthy food consumption. In the control group, consumption of non-healthy food was stable, with a decrease in fruits and vegetables consumption. As it was demonstrated in similar studies, a short interactive nutrition education intervention with utilization of ICT in pre basic and basic teachers can produce positive changes in nutritional status of their students, improving food knowledge and healthy food consumption and decreasing non-healthy food consumption, compared with the control group. However, a strategy to incorporate parents in school nutrition education programs is still a pending issue. Copyright AULA MEDICA EDICIONES 2014. Published by AULA MEDICA. All rights reserved.

Prevalence of high frequency hearing loss consistent with noise exposure among people working with sound systems and general population in Brazil: A cross-sectional study

2008-01-01

Background Music is ever present in our daily lives, establishing a link between humans and the arts through the senses and pleasure. Sound technicians are the link between musicians and audiences or consumers. Recently, general concern has arisen regarding occurrences of hearing loss induced by noise from excessively amplified sound-producing activities within leisure and professional environments. Sound technicians' activities expose them to the risk of hearing loss, and consequently put at risk their quality of life, the quality of the musical product and consumers' hearing. The aim of this study was to measure the prevalence of high frequency hearing loss consistent with noise exposure among sound technicians in Brazil and compare this with a control group without occupational noise exposure. Methods This was a cross-sectional study comparing 177 participants in two groups: 82 sound technicians and 95 controls (non-sound technicians). A questionnaire on music listening habits and associated complaints was applied, and data were gathered regarding the professionals' numbers of working hours per day and both groups' hearing complaint and presence of tinnitus. The participants' ear canals were visually inspected using an otoscope. Hearing assessments were performed (tonal and speech audiometry) using a portable digital AD 229 E audiometer funded by FAPESP. Results There was no statistically significant difference between the sound technicians and controls regarding age and gender. Thus, the study sample was homogenous and would be unlikely to lead to bias in the results. A statistically significant difference in hearing loss was observed between the groups: 50% among the sound technicians and 10.5% among the controls. The difference could be addressed to high sound levels. Conclusion The sound technicians presented a higher prevalence of high frequency hearing loss consistent with noise exposure than did the general population, although the possibility of residual confounding due to unmeasured factors such as socioeconomic status cannot be ruled out.

The objective of our randomized, double-blind study was to compare the effectiveness of intratympanic (IT) dexamethasone versus high-dosage of betahistine in the treatment of patients with intractable unilateral Meniere disease (MD). Sixty six patients with definite unilateral MD were randomly divided in two groups: Group A received a combination of IT dexamethasone (DX) and identical-appearing placebo pills while Group B received a combination of high-dosage betahistine and IT saline. Intratympanic injections were repeated for three times with an interlude of 3days. High-dosage of betahistine entailed 144mg/day. Mean outcome measures consisted of vertigo control, pure tone average (PTA), speech discrimination score, Functional Level Score, Dizziness Handicap Inventory and Tinnitus Handicap Inventory. Fifty nine patients completed the study and were available at 12months for analysis. In Group A complete vertigo control (class A) was attained in 14 patients (46.6%) and substantial control (class B) in 7 patients (20%). In Group B, 12 patients (41%) achieved complete vertigo control (class A), 5 patients (17%) substantial control (class B). There is no statistical difference in vertigo control between the two treatment groups. In Group A hearing was unchanged in 14 patients and improved in 4 patients, while in Group B hearing was unchanged in 16 patients and improved in 2 patients. Our preliminary results demonstrate that high-dosage of betahistine achieved similar outcomes as IT dexamethasone in the control of vertigo and hearing preservation. Copyright © 2015 Elsevier Inc.

Critical thinking is essential to nursing practice. This study examined differences in the critical thinking dispositions of registered nurses (RNs) in a nursing fellowship program. Control and experimental groups were used to compare differences in scores on the California Critical Thinking Disposition Inventory (CCTDI) of RNs at three points during a fellowship program: baseline, week 7, and month 5. The control group consisted of RNs who received no education in critical thinking. The experimental group received education in critical thinking using simulated scenarios and reflective journaling. CCTDI scores examined with analysis of variance showed no significant difference within groups over time or between groups. The baseline scores of the experimental group were slightly higher than those of the control group. Chi-square analysis of demographic variables between the two groups showed no significant differences. Critical thinking dispositions are a combination of attitudes, values, and beliefs that make up one's personality based on life experience. Lack of statistical significance using a quantitative approach did not capture the development of the critical thinking dispositions of participants. A secondary qualitative analysis of journal entries is being conducted. Copyright 2013, SLACK Incorporated.

To evaluate the levels of glycated hemoglobin (HbA1c) in patients heterozygous for hemoglobin variants and compare the results of this test with those of a control group. This was an experimental study based on the comparison of HbA1c tests in two different populations, with a test group represented by individuals heterozygous for hemoglobin variants (AS and AC) and a control group consisting of people with electrophoretic profile AA. The two populations were required to meet the following inclusion criteria: Normal levels of fasting glucose, hemoglobin, urea and triglycerides, bilirubin > 20 mg/dL and non-use of acetylsalicylic acid. 50 heterozygous subjects and 50 controls were evaluated between August 2013 and May 2014. The comparison of HbA1c levels between heterozygous individuals and control subjects was performed based on standard deviation, mean and G-Test. The study assessed a test group and a control group, both with 39 adults and 11 children. The mean among heterozygous adults for HbA1c was 5.0%, while the control group showed a rate of 5.74%. Heterozygous children presented mean HbA1c at 5.11%, while the controls were at 5.78%. G-Test yielded p=0.93 for children and p=0.89 for adults. Our study evaluated HbA1c using ion exchange chromatography resins, and the patients heterozygous for hemoglobin variants showed no significant difference from the control group.

The role of gastrointestinal peptides in eating disorders has yet to be determined. Methods: In this study we examined plasma levels of gastrin (G), cholecystokinin (CCK), and pancreatic polypeptide (PP) in adolescent anorexic, and obese female subjects hospitalized for feeding behavior disorders. Six anorexic, six obese and six control young females (ages 13-26) were studied after an overnight fast and after consuming a liquid test meal. The liquid test meal (Ensure, Ross Laboratories; Columbus OH) consisted of 14% calories as protein, 31.5% calories as fat and 54.5% calories as carbohydrate in a 240ml volume. Plasma levels of gastrointestinal peptides, G,more » CCK and PP were determined by specific radioimmunoassay. The data were analyzed by one way analysis of variance and the Student's t-test. Results: show that fasting levels of G were greater in control and obese groups than the anorexic subjects. Postprandial G levels for controls were higher than the anorexic, and obese groups respectively. When fasting and postprandial G levels were compared among the same groups only the controls increased after eating. Fasting CCK levels were lower in control and anorexic groups than the obese group. Postprandial CCK levels were higher among control patients compared to anorexic and obese subjects. When fasting and postprandial CCK levels were compared among groups, only control levels increased after eating. Fasting and postprandial PP levels were not different between groups. Postprandial PP levels increased over fasting PP levels only in controls.« less

Spelling deficits have repeatedly been observed in children with dyslexia. However, the few studies addressing this issue in dyslexic adults have reported contradictory results. We investigated whether Spanish dyslexics show spelling deficits in adulthood and which components of the writing production process might be impaired in developmental dyslexia. In order to evaluate the involvement of the lexical and the sublexical routes of spelling as well as the graphemic buffer, lexical frequency, phonology-to-orthography consistency and word length were manipulated in two writing tasks: a direct copy transcoding task and a spelling-to-dictation task. Results revealed that adults with dyslexia produced longer written latencies, inter-letter intervals, writing durations and more errors than their peers without dyslexia. Moreover, the dyslexics were more affected by lexical frequency and word length than the controls, but both groups showed a similar effect of P-O consistency. Written latencies also revealed that while the dyslexics initiated the response later in the direct copy transcoding task than in the spelling-to-dictation task, the controls showed the opposite pattern. However, the dyslexics were slower than the controls in both tasks. Results were consistent with the hypothesis that spelling difficulties are present in adults with dyslexia, at least in a language with a transparent orthography such as Spanish. These difficulties seem to be associated with a deficit affecting both lexical processing and the ability to maintain information about the serial order of the letters in a word. However, the dyslexic group did not differ from the control group in the application of the P-O conversion procedures. The spelling impairment would be in addition to the reading deficit, leading to poorer performance in direct copy transcoding compared to spelling-to-dictation.

The purpose of this study was to evaluate the effect of group hypnotherapy on anxiety, depression, stress, self-esteem, optimism, and social support during chemotherapy, in patients with breast cancer, compared with a control group with standard medical care. Hypnotherapy consisted of 24 sessions that included suggestions to encourage relaxation, self-esteem, the resolution of past traumatic events, physical healing, and optimism. Results show that the hypnotherapy group significantly decreased anxiety, distress, increased self-esteem, and optimism in the first 12 sessions. However, at the end of the 24 sessions, only self-esteem and optimism remained significant compared with the control group. The convenience of using hypnotherapy to encourage optimism and self-esteem in patients with breast cancer during chemotherapy treatment is discussed given its protective effect on health.

In this study we evaluated a social skills group which employed a progressive applied behavior analysis model for individuals diagnosed with autism spectrum disorder. A randomized control trial was utilized; eight participants were randomly assigned to a treatment group and seven participants were randomly assigned to a waitlist control group. The social skills group consisted of 32, 2 h sessions. Teachers implemented a variety of behaviorally based procedures. A blind evaluator measured participants' behavior immediately prior to intervention, immediately following intervention, and during 16 and 32-week maintenance probes. Results of the study demonstrated that participants made significant improvements with their social behavior (p < .001) following intervention, and the results were maintained up to 32 weeks after intervention had concluded.

Religious values were investigated in a group of Iranian Revolutionary Guards in Tehran. The sample consisted of official duty troops and conscripts who were in prison due to a crime. One hundred thirty seven individuals cooperated with us in the project (37 Official personnel and 100 conscripts). The instruments used included a demographic questionnaire containing personal data and the Allport, Vernon and Lindzey's Study of Values Test. Most statistical methods used descriptive statistical methods such as frequency, mean, tables and t-test. The results showed that religious value was lower in the criminal group than the control group (p<.001). This study showed lower religious value scores in the criminals group, suggesting the possibility that lower religious value increases the probability of committing crimes.

Chronic social instability increases anxiety-like behavior and ethanol preference in male Long Evans rats.

Chronic stress during adolescence is related to increased prevalence of anxiety disorders and alcohol use disorders in humans. This phenotype has been consistently recapitulated in animal models with male subjects, but models using female subjects are fewer. The aim of these studies was to test the hypothesis that chronic social instability (CSI) during adolescence engenders increased anxiety-like behavior, increased corticosterone, and greater ethanol intake and/or preference than control groups in male and female rats. A chronic social instability (CSI) procedure was conducted in separate cohorts of female and male adolescent Long Evans rats. CSI included daily social isolation for 1h, and then pair housing with a novel cage mate for 23h until the next 1h isolation period from PND 30-46. Control groups included social stability (SS), chronic isolation (ISO), and acute social instability (aSI). At PND 49-50, anxiety-like behavior was assessed on the elevated plus maze, and on PND 51 tails bloods were obtained for determination of corticosterone (CORT) levels. This was followed by 4weeks of ethanol drinking in a home cage intermittent access ethanol drinking paradigm (PND 55-81 for males, PND 57-83 for females). Planned contrast testing showed that the male CSI group had greater anxiety-like behavior compared controls, but group differences were not apparent for CORT. CSI males had significantly higher levels of ethanol preference during drinking weeks 2-3 compared to all other groups and compared to SS and ISO groups in week 4. For the female cohort, we did not observe consistent group differences in anxiety-like behavior, CORT levels were unexpectedly lower in the ISO group only compared to the other groups, and group differences were not apparent for ethanol intake/preference. In conclusion, chronic stress during adolescence in the form of social instability increases anxiety-like behavior and ethanol preference in male rats, consistent with other models of chronic stress during adolescence. Conversely, and contrary to our hypothesis, female rats' anxiety-like behavior, CORT level, and ethanol intake/preference were not altered by CSI. New paradigms must continue to be explored for study of clinically relevant relationships in female preclinical models. Copyright © 2017 Elsevier Inc. All rights reserved.

This study aimed to evaluate the effects of juniper essential oil on the growth performance, rumen fermentation parameters, rumen protozoa population, blood antioxidant enzyme parameters and faecal content in growing Saanen kids. Thirty-six male Saanen kids (36 ± 14 days of age) were used in the study. Each group consisted of 9 kids. The control group (G1) was fed with a diet that consisted of the above concentrated feed and oat hay, whereas the experimental groups consumed the same diet but with the concentrated feed uniformly sprayed with juniper essential oil 0.4 ml/kg (G2), 0.8 ml/kg (G3) or 2 ml/kg (G4). There were no differences (p > 0.05) in live weight, live weight gain or feed consumption between the control and experimental groups. There was a significant improvement (p < 0.05) in feed efficiency in the G3 group. There were no differences in the rumen pH, rumen volatile fatty acid (VFA) profile or faecal pH of the control and experimental groups. The rumen NH 3 N values were similar at the middle and end of the experiment, but at the start of the experiment, the rumen NH 3 N values differed between the control and experimental groups (p < 0.05). The faecal score value was significantly (p < 0.05) decreased in the experimental groups. The addition of juniper essential oil supplementation to the rations caused significant effects on the kids' antioxidant blood parameters. Although the superoxide dismutase (SOD) activity, total antioxidant capacity (TAC) and catalase values were significantly (p < 0.05) increased in the experimental groups (G2, G3 and G4), especially group G4, the blood glutathione peroxidase (GPX) value significantly decreased in the experimental groups. The results of this study suggest that supplementation of juniper oil is more effective on antioxidant parameters than on performance parameters and may be used as a natural antioxidant product.

To study the protective effects of polysaccharides from Dendrobium huoshanense (DHP) against CCl4-induced liver injury in mice. Eighty male Kunming mice were randomly divided into normal control group, model control group, dextran control group, starch control group, hydrolyzate control group, three different dose of DPH groups consisting of high-dosage group, middle-dosage group and low-dosage group (200, 100, 50 mg x kg(-1)). Each group contained ten mice. The mice were treated with DHP via intragastric administration for 15 days before treatment of 50% CCl4 in olive oil for consecutive two days. Both alanine aminotransferase (ALT) and aspartate aminotransferase (AST) activities in serum and superoxide dismutase (SOD) activities and malondialdehyde (MDA) contents in liver tissues were determined in all groups. Immunohistochemistry was used to detect the expression of TNF-alpha in hepatic tissue. Hepatic histopathological examination was observed. DHP effectively decreased the activities of ALT and AST in serum and the contents of hepatic MDA, and restored hepatic SOD activities in acute liver injury mice. Liver tissue damage induced by CCl4 was ameliorated in mice with DHP administration through histopathology examination. Furthermore, the expression of TNF-alpha was greatly decreased in groups treated with polysaccharides. DHP has a significantly hepatoprotective effect on CCl4-induced acute liver injury in mice. Protective effect of DHP on the liver may be related to its function of scavenging free radicals and inhibiting lipid peroxidation and TNF-alpha expression.

Physiotherapy, and speech and language therapy are emerging non-pharmacological treatments for refractory chronic cough. We aimed to investigate the efficacy of a physiotherapy, and speech and language therapy intervention (PSALTI) to improve health-related quality of life (HRQoL) and to reduce cough frequency in patients with refractory chronic cough. In this multicentre randomised controlled trial, patients with refractory chronic cough were randomised to four weekly 1:1 sessions of either PSALTI consisting of education, laryngeal hygiene and hydration, cough suppression techniques, breathing exercises and psychoeducational counselling or control intervention consisting of healthy lifestyle advice. We assessed the change in HRQoL at week 4 with the Leicester Cough Questionnaire (LCQ). Secondary efficacy outcomes included 24-hour objective cough frequency (Leicester Cough Monitor) and cough reflex sensitivity. The primary analysis used an analysis of covariance adjusted for baseline measurements with the intention-to-treat population. This study was registered at UK Clinical Research Network (UKCRN ID 10678). Between December 2011 and April 2014, we randomly assigned 75 participants who underwent baseline assessment (34 PSALTI and 41 controls). In the observed case analysis, HRQoL (LCQ) improved on average by 1.53 (95% CI 0.21 to 2.85) points more in PSALTI group than with control (p=0.024). Cough frequency decreased by 41% (95% CI 36% to 95%) in PSALTI group relative to control (p=0.030). The improvements within the PSALTI group were sustained up to 3 months. There was no significant difference between groups in the concentration of capsaicin causing five or more coughs. Greater improvements in HRQoL and cough frequency were observed with PSALTI intervention. Our findings support the use of PSALTI for patients with refractory chronic cough.

The aim of this study was to elucidate the cause of a neurological syndrome characterized by stridor in adult goats with clinical signs of copper deficiency. The main clinical signs consisted of apathy, emaciation, pale mucous membranes, mucous nasal discharge, dyspnea, severe achromotrichia, diffuse alopecia, torpor, ataxia, and stridor. When the goats were forced to move, the stridor increased. In a herd of 194 Toggenburg goats, 10 adult goats with clinical signs of copper deficiency were removed from the herd and divided into 2 groups: group 1, which consisted of 4 nannies and 1 buck with stridor, and group 2, which consisted of 4 nannies and 1 buck without stridor. Group 3, used as a control, consisted of 5 adult goats from another flock without any clinical signs of disease. The mean serum copper concentrations were 1.3 ± 0.3 μmol/L in group 1, 8.1 ± 1.1 μmol/L in group 2, and 11.3 ± 2.2 μmol/L in group 3. The mean serum iron concentrations were 42.3 ± 14.2 μmol/L in group 1, 39.1 ± 8.2 μmol/L in group 2, and 20.6 ± 6.1 μmol/L in group 3. The main histological lesions in goats from group 1 were axonal degeneration of the recurrent laryngeal nerves and atrophy of the muscles of vocal folds and of the dorsal cricoarytenoid and right and left cricothyroid muscles. Goats with ataxia had neuronal degeneration and necrosis of cerebellar Purkinje cells and of the cranial cervical ganglion. We concluded that the stridor was caused by axonal degeneration of the recurrent laryngeal nerves due to the severe copper deficiency.

This is a randomized controlled trial that aimed to evaluate the effect of the Seven-star Needle Stimulation treatment on children with Autistic Spectrum Disorders (ASD). Thirty-two children with ASD were assigned randomly into the treatment and control groups. Children in the treatment group underwent 30 sessions of stimulation over 6 weeks, while children in the control group were on a waiting list and did not receive treatment during this period of time. Intervention consisted of a treatment regime comprising of 30 sessions of Seven-star Needle Stimulation, delivered over 6 weeks. Each session lasted 5 to 10 min, children in the treatment group were stimulated at the front and back sides of their body and the head by using Seven-star Needles. The change in the children's behavior was evaluated using parents' report and neurophysiological changes were measured by quantitative EEG (qEEG). Results showed that the treatment group demonstrated significant improvement in language and social interaction, but not in stereotyped behavior or motor function, compared to the control group. qEEG spectral amplitudes in the treatment, but not in the control group, were also reduced significantly. The results suggested that Seven-star Needle Stimulation might be an effective intervention to improve language and social functioning of children with ASD.

Climateric is considered to be a natural phase of life which by definition is the period of life starting from decline in ovarian activity until after the end of ovarian function. It is accompanied by various health consequences that include the changes in saliva too. This study was carried out to evaluate the salivary flow rate, pH, buffering capacity in pre-menopausal, post-menopausal and post-menopausal women on HRT. (1) To evaluate the salivary flow rate, pH of resting saliva and stimulated saliva and buffer capacity of stimulated saliva in pre-menopausal, post-menopausal and post-menopausal women on Hormone Replacement Therapy (HRT). (2) To compare the above salivary findings between pre-menopausal, post-menopausal and post-menopausal women on HRT. The study was carried out on 60 patients. These patients were divided into three groups of 20 patients: Group 1: Pre-menopausal women (control), Group 2: post-menopausal women (case), Group 3: post-menopausal women on HRT (case). The control group consisted of 20 women volunteers, having regular ovulatory menstrual cycles with no known systemic illness and deleterious habits and Group 2 consists of 20 post-menopausal women and Group 3 will consist of 20 post-menopausal women on HRT. After clearing the mouth by swallowing, stimulated saliva was collected after chewing paraffin for 10 mins in to a glass centrifuge tube graded in 0.1 mL increments up to 10mL.in rare cases the collection time will be reduced or extended (5-15 min), salivary flow rate will be determined as ml/min, immediately after collection, pH was determined by dipping pH test paper directly into the sample of oral fluid, salivary buffer capacity was determined by using saliva check buffer kit (GC corporation). The data obtained was statistically evaluated using chi-square test, fisher exact test ANOVA analysis. In our study we found salivary flow rate significantly lower in the post-menopausal women in comparison with the menstruating women and also there was improvement in the flow rate in individuals who were on HRT, it was also observed that salivary pH of the post-menopausal group was significantly lower than that of the control group, statistically significant difference in buffer capacity values was found between the groups however buffer capacity values were higher in the post-menopausal group than the control group. From the above study it is clear that post-menopausal women will present with oral discomfort, while HRT can improve the same. Hence our role as physicians and health care providers is to incorporate preventive dental health care in post-menopausal women and clearly inform patients about both the benefits and the limitations of HRT.

This study was conducted to determine the effects of a fall prevention program on falls, physical function, psychological function, and home environmental safety in frail elders living at home in rural communities. The design of this study was a nonequivalent control group pre posttest design. The study was conducted from July to November, 2012 with 30 participants in the experimental group and 30 in the control group. Participants were registered at the public health center of E County. The prevention program on falls consisted of laughter therapy, exercise, foot care and education. The program was provided once a week for 8 weeks and each session lasted 80 minutes. The risk score for falls and depression in the experimental group decreased significantly compared with scores for the control group. Compliance with prevention behavior related to falls, knowledge score on falls, safety scores of home environment, physical balance, muscle strength of lower extremities, and self-efficacy for fall prevention significantly increased in the experimental group compared with the control group. These results suggest that the prevention program on falls is effective for the prevention of falls in frail elders living at home.

Although several effects of electromagnetic fields (EMFs) on articular cartilage have been reported in recent studies, the use of EMFs to treat osteoarthritis remains a matter of debate. In an in vitro study, human chondrocytes harvested from osteoarthritic knee joints were released from their surrounding matrix and transferred in defined concentration into a 3D matrix (type-I collagen gel). The cultivation, performed under standard conditions, lasted up to 14 days. During this time, treatment groups were continuously exposed to either sinusoid or pulsed electromagnetic fields (PEMFs). The PEMFs revealed the following characteristics: maximum magnetic flux density of 2 mT, frequency of the bursts of 16.7 Hz with each burst consisting of 20 pulses. Similarly, the sinusoid EMFs also induced a maximum flux density of 2 mT with a frequency of 50 Hz. Control groups consisting of equal number of samples were not exposed to EMF. Immunohistological examinations of formalin-fixed, paraffin-embedded samples revealed positive staining for type-II collagen and proteoglycans in the immediate pericellular region with no differences between the two different treatment groups and the control groups. With increasing cultivation time, both type-II collagen and aggrecan gene expression declined, but no significant differences in gene expression were found between the treatment and control groups. In conclusion, using our in vitro setting, we were unable to detect any effects of pulsed and sinusoidal magnetic fields on human adult osteoarthritic chondrocytes.

Objective. The risk of atherosclerotic heart disease is increased in autoimmune thyroiditis, although the reason is not clear. Lipoprotein(a) (Lp(a)) excess has been identified as a powerful predictor of premature atherosclerotic vascular diseases. The aim of this study is to investigate the relationship between Lp(a) levels and thyroid hormones in Hashimoto patients. Method. 154 premenopausal female Hashimoto patients (48 patients with overthypothyroid (OH), 50 patients with subclinical hypothyroid (SH), and 56 patients with euthyroid Hashimoto to (EH)) were enrolled in this study. The control group consists of 50 age matched volunteers. In every group, thyroid function tests and lipid parameters with Lp(a) were measured. Lp(a) excess was defined as Lp(a) > 30 mg/dL. Results. Total-C, LDL-C, TG, and Lp(a) levels were increased in Hashimoto group. Total-C, LDL-C, and TG levels were higher in SH group than in the control group. Total-C and LDL-C levels were also higher in EH group compared to controls. Lp(a) levels were similar in SH and EH groups with controls. However, excess Lp(a) was more common in subclinical hypothyroid and euthyroid Hashimoto group than in the control group. Conclusion. The Total-C and LDL-C levels and excess Lp(a) were higher even in euthyroid Hashimoto patients. Thyroid autoimmunity may have some effect on Lp(a) and lipid metabolism.

A herbal powder consisting of Guargum, Methi, Tundika and Meshasringi was administered to thirty control and thirty NIDDM patients twice daily before principal meals for four weeks. Oral GTT showed improvement in both control and patient groups. Serum total and LDL cholesterol also fell significantly in both the groups after the trial period. Test meal of the herbal powder with D-Xylose excretion was otherwise normal. Follow up for upto two years did not reveal any long term side effect of the powder. This powder, therefore, can be effectively used to reduce postprandial blood glucose and LDL cholesterol in NIDDM patients as a long term measure.

Two groups of killifish, Fundulus heteroclitus, which were flown aboard Apollo-Soyuz, were subjected to postflight behavioral testing. The first group examined consisted of a graded series of embryos representing key developmental stages at orbital insertion (32-h, 66-h, and 128-h stages; pre-liftoff fertilization times). The tests revealed that the young adults from the flight 32-h stage had a significantly decreased positive geotaxis and increased negative phototaxis when compared with ground controls. These findings suggested a greater sensitization of the least-developed flight stage to post-hatching environmental influences. The second group consisted of 21-d old juveniles which were subjected to light orientation tests soon after recovery. No significant differences were detected.

The relationship between articulatory control and improved phonemic accuracy in childhood apraxia of speech: A longitudinal case study

2010-01-01

Jaw movement patterns were examined longitudinally in a 3-year-old male with childhood apraxia of speech (CAS) and compared with a typically developing control group. The child with CAS was followed for 8 months, until he began accurately and consistently producing the bilabial phonemes /p/, /b/, and /m/. A movement tracking system was used to study jaw duration, displacement, velocity, and stability. A transcription analysis determined the percentage of phoneme errors and consistency. Results showed phoneme-specific changes which included increases in jaw velocity and stability over time, as well as decreases in duration. Kinematic parameters became more similar to patterns seen in the controls during final sessions where tokens were produced most accurately and consistently. Closing velocity and stability, however, were the only measures to fall within a 95% confidence interval established for the controls across all three target phonemes. These findings suggest that motor processes may differ between children with CAS and their typically developing peers. PMID:20030551

To evaluate implant and prosthesis movement after myoconjunctival enucleation and subsequent polymethyl methacrylate (PMMA) implantation, compared with the traditional enucleation with muscle imbrication using a PMMA implant and with enucleation accompanied by porous polyethylene implantation. Randomized, controlled, observer-masked, interventional study. One hundred fifty patients, equally and randomly allocated to the 3 groups. Group 1 consisted of patients in whom a PMMA implant was used after enucleation with muscle imbrication (traditional PMMA group). Group 2 consisted of patients in whom a PMMA implant was used after enucleation with a myoconjunctival technique (myoconjunctival PMMA group). Group 3 consisted of patients in whom a porous polyethylene implant was used after enucleation by the scleral cap technique (porous polyethylene group). Fifty patients were included in each group. Patients were allocated to 1 of the 3 groups using stratified randomization. Informed consent was obtained. Acrylic prostheses custom made by a trained ocularist were fitted 6 weeks after surgery in all patients. A masked observer measured implant and prosthesis movement 6 weeks after surgery using a slit-lamp device with real-time video and still photographic documentation. Analysis of implant and prosthesis movement was carried out using the Mann-Whitney U test, and a P value of < or =0.03 was considered significant. Complications including implant displacement and exposure also were noted. Implant and prosthesis movement. Myoconjunctival PMMA implant movement was better than the traditional PMMA implant (P = 0.001), but was similar to that of the porous polyethylene implant. Prosthesis movement with the myoconjunctival PMMA implant was better than that of either the traditional PMMA (P = 0.001) or porous polyethylene (P = 0.002) implants. Myoconjunctival enucleation technique with a PMMA implant provides statistically and clinically significantly better implant and prosthesis movement than the traditional PMMA implant and better prosthesis movement than the porous polyethylene implant.

Objective: To establish a canine model of slow transit constipation (STC), and to test the changes in defecation, gastrointestinal transit time and pathology sections. Methods: Baseline information was measured in 8 beagle dogs, and these dogs were randomly divided into the control group and the model group. The dogs in model group were given a diet of canned meat, as well as a combination of compound diphenoxylate and alosetron hydrochloride for 5 weeks. Dogs in control group were given normal diet with no special intervention. Stool frequency and consistency were observed and recorded daily, and the gastrointestinal transit time (GITT) were measured every week. All animals underwent the midline laparotomy and the colonic tissues were taken from the rectosigmoid colon, then investigated by light microscopy, electron microscopy, and immunohistochemistry to evaluate changes of protein gene product 9.5(PGP9.5), synaptophysin and c-kit between two groups. Results: 8 beagle dogs underwent all experiment items successfully.Both of the stool frequency and scores of stool consistency decreased in model group( F =6.568, P =0.043; F =25.954, P =0.002). GITT delayed in model group( F =42.573, P =0.001). After 5 weeks of intervention, in the model group, the myenteric neurons and interstitial cells of Cajal showed damage such as swelling of mitochondria under electron microscopy, and both of the PGP9.5 and synaptophysin integrated option density of rectosigmoid colon were decreased ( t =3.471, P =0.013; t =2.506, P =0.046)under immunohistochemistry. The c-kit integrated option density showed no statistically significant differences between two groups( t =1.709, P =0.138). Conclusions: The canine model of STC which was consistent with clinical symptoms and pathological changes was successfully established, and it can be used to observe and evaluate the therapeutic effect of electrical stimulation, surgery and so on.

There are many discrepancies among the results of studies on the genotoxicity of lead. The aim of the study was to explore lead-induced DNA damage, including oxidative damage, in relation to oxidative stress intensity parameters and the antioxidant defense system in human leukocytes. The study population consisted of 100 male workers exposed to lead. According to the blood lead (PbB) levels, they were divided into the following three subgroups: a group with PbB of 20-35 μg/dL (low exposure to lead (LE) group), a group with a PbB of 35-50 µg/dL (medium exposure to lead (ME) group), and a group with a PbB of >50 μg/dL (high exposure to lead (HE) group). The control group consisted of 42 healthy males environmentally exposed to lead (PbB < 10 μg/dL). A comet assay was used to measure the DNA damage in leukocytes. We measured the activity of superoxide dismutase (SOD), catalase, glutathione reductase (GR), glucose-6-phosphate dehydrogenase (G6PD), and glutathione-S-transferase (GST) as well as the concentration of malondialdehyde (MDA), and the value of the total antioxidant capacity. The level of PbB was significantly higher in the examined subgroups than in the control group. The percentage of DNA in the tail was significantly higher in the LE, ME, and HE subgroups than in the control group by 10% ( p = 0.001), 15% ( p < 0.001), and 20% ( p < 0.001), respectively. The activity of GR was significantly lower in the LE and ME subgroups than in the control group by 25% ( p = 0.007) and 17% ( p = 0.028), respectively. The activity of G6PD was significantly lower in the ME subgroup by 25% ( p = 0.022), whereas the activity of GST was significantly higher in the HE subgroup by 101% ( p = 0.001) than in the control group. Similarly, the activity of SOD was significantly higher in the LE and ME subgroups by 48% ( p = 0.026) and 34% ( p = 0.002), respectively. The concentration of MDA was significantly higher in the LE, ME, and HE subgroups than in the control group by 43% ( p = 0.016), 57% ( p < 0.001), and 108% ( p < 0.001), respectively. Occupational lead exposure induces DNA damage, including oxidative damage, in human leukocytes. The increase in DNA damage was accompanied by an elevated intensity of oxidative stress.

Prospective, controlled study with waiting group (control group, n = 18) and e-learning group (n = 20). The control group got the same reference literature list as the e-learning group. Both groups were assessed twice: The e-learning group before and after the course; the control group was assessed at the same times. increase in knowledge about genetics of epilepsies using questionnaires based on items formulated by experts (internal consistency, Cronbach's alpha = 0.86). Main hypothesis: greater increase of knowledge in the e-learning group compared to control group. assessment of the educational course and learning environment by participants and by tutors/e-moderators. Significant time x group interaction and group effect (ANOVA, each p < 0.01) with regard to knowledge. At baseline, the groups did not differ with respect to knowledge about genetics of epilepsy. In contrast to the control group, the increase of knowledge in the e-learning group was highly significant (p < 0.001). The majority of the participants of the e-learning course was content with their personal learning process (75% agree, 15% strongly agree). Most of them reported a gain in competence in the treatment and counseling of people with epilepsy (38.9% agree, 50% strongly agree). All participants would recommend this course to others and all but one participant are interested in other e-learning courses. The study indicates e-learning courses are an appropriate tool to improve knowledge of physicians in genetics of epilepsy.

The goal of this study was to examine the possibility of partial replacement of sodium chloride with potassium chloride and ammonium chloride, with the target of achieving less sodium content in meatballs and tomato sauce as well as achieving a better Na:K ratio. The trial consisted of five groups. In the control group of meatballs and sauce, only sodium chloride was added. In group 1, half of the sodium chloride was replaced with potassium chloride related to control group while in group 2 one third of the sodium chloride was replaced with potassium chloride. In group 3, one third of the sodium chloride was replaced with ammonium chloride, and in group 4, sodium chloride was reduced to half the amount in the control group, and 1 g (0.25%) of ammonium chloride was also added. All products were acceptable according to sensory analyses. The largest reductions of sodium content were 44.64%, achieved in meatballs from group 1 and 50.62% in tomato sauce from group 4 in relation to meatballs and tomato sauce from control group. The highest Na:K ratio was calculated in meatballs and tomato sauce from control group, 2.88 and 4.39, respectively. The best Na:K ratio was in meatballs and tomato sauce from group 1, 0.60 and 0.92, respectively, in which half of sodium chloride was replaced with potassium chloride. However, in meatballs and tomato sauce from group 4, with only half the amount of sodium chloride related to control group, the Na:K ratio was worse because in these products, potassium chloride was not added.

Peptic ulcer perforation (PUP) accounts for 5% of all abdominal emergencies and is recognized as a gastrointestinal emergency requiring rapid and efficient clinical evaluation and treatment. The mortality rate ranges from 10% to 40% among patients with perforation. In the present retrospective study, we examined the potential utility of the neutrophil-to-lymphocyte ratio (NLR) in early diagnosis of PUP; we asked whether this ratio allowed PUP and peptic ulcer disease to be distinguished. We enrolled the following patients: 58 with PUP, 62 with noncomplicated peptic ulcer diseases (NCPU), and 62 controls, between May 2010 and 2015. Patients who underwent surgical repair to treat PUP were included in the study group. Another group consisted of NCPU patients who had a noncomplicated peptic ulcer. The control group consisted of patients presenting with nonspecific abdominal pain to the emergency department. The mortality rate was 5.2% in the PUP group. The white blood cell count, C-reactive protein, and NLRs were higher in the PUP compared to the other groups (P<.001 for all). The white blood cell count and NLR did not differ between the NCPU and control groups. The sensitivities, specificities, positive predictive values, and negative predictive values of the NLRs were 68.0%, 88.0%, 82.9%, and 72.9%, respectively. We suggest that preoperative NLR aids in the diagnosis of PUP and can be used to distinguish this condition from peptic ulcer disease. Thus, the NLR should be calculated in addition to the clinical examination. Copyright © 2015 Elsevier Inc. All rights reserved.

We evaluated the effectiveness of an HIV/STD risk-reduction intervention when implemented by community-based organizations (CBOs). In a cluster-randomized controlled trial, 86 CBOs that served African American adolescents aged 13 to 18 years were randomized to implement either an HIV/STD risk-reduction intervention whose efficacy has been demonstrated or a health-promotion control intervention. CBOs agreed to implement 6 intervention groups, a random half of which completed 3-, 6-, and 12-month follow-up assessments. The primary outcome was consistent condom use in the 3 months prior to each follow-up assessment, averaged over the follow-up assessments. Participants were 1707 adolescents, 863 in HIV/STD-intervention CBOs and 844 in control-intervention CBOs. HIV/STD-intervention participants were more likely to report consistent condom use (odds ratio [OR] = 1.39; 95% confidence interval [CI] = 1.06, 1.84) than were control-intervention participants. HIV/STD-intervention participants also reported a greater proportion of condom-protected intercourse (beta = 0.06; 95% CI = 0.00, 0.12) than did the control group. This is the first large, randomized intervention trial to demonstrate that CBOs can successfully implement an HIV/STD risk-reduction intervention whose efficacy has been established.

This study aims to identify subgroups of consumers based on the health motives underlying their food choice in Western Balkan Countries. The survey (n = 2943) was based on the Food Choice Questionnaire (FCQ) and elicited information on socio-demographic characteristics, consumption frequency of healthy food products, nutrition knowledge and impulsiveness. Analysis of the FCQ data focused on items of "health and natural content" and "weight control" factors to identify clusters. The biggest group of the sample was weight control and health-concerned individuals (34 %), mainly urban women older than 50. The second group of respondents (31 %) was moderately motivated about health and weight. A third group was health concerned but paid less attention to weight control (21 %), mainly comprising men and people living with children. The last group consisted of unconcerned young men (14 %) eating less fruit and showing higher impulsiveness. Western Balkan consumers differ in the importance they attach to health and natural content and weight control. This insight is needed to target interventions.

This study used a quasi-experimental design with a pretest-posttest control group and follow-up to determine the efficacy of adherence therapy in patients with schizophrenia in Turkey. The sample of this study consisted of patients with schizophrenia (n=30). The Questionnaire Form, Medication Adherence Rating Scale, Internalized Stigma of Mental Illness Scale, and Beck Cognitive Insight Scale were used. The patients were assigned to experimental (n=15) and control (n=15) groups using the randomization method. The experimental group received adherence therapy in eight sessions. When the scores of the patients in the experimental and control groups were compared at the pretest, posttest, and 3- and 6-months follow ups, a significant difference was only found in the Medication Adherence Rating Scale posttest scores. Adherence therapy is effective in improving adherence to treatment but is not effective with regard to insight and internalized stigma in patients with schizophrenia. Copyright © 2015 Elsevier Inc.

Over the past decade, strong evidence for an association between maternal periodontitis and low birthweight has started to appear. However, few intervention studies have been proposed for investigating this hypothesis. The aim of this study was to evaluate whether periodontal therapy among pregnant women would reduce the incidence of low birthweight. A nonrandomized intervention study was performed, with two control groups. The sample comprised 339 pregnant women: 141 in the experimental group (treated for periodontitis), 145 in control group 1 (without periodontitis) and 53 in control group 2 (with untreated periodontitis). The experimental group received periodontal treatment throughout pregnancy, whereas control group 1 was only monitored over the same period. After delivery, birthweight information on the newborns was obtained. The analysis procedures consisted of stratified analysis followed by logistic regression. The frequency of low birthweight among the women with treated periodontitis was 9.22%, while it was 13.10% in the group without periodontal disease. However, the difference was not statistically significant (RR 0.72; 95% CI 0.36-1.45). The occurrence of this outcome in the group with untreated periodontitis (24.53%) was greater than in the other two groups. This suggests that periodontal therapy is a protective factor for birthweight.

Using a genome-wide single nucleotide polymorphism (SNP) panel, we observed population structure in a diverse group of Europeans and European Americans. Under a variety of conditions and tests, there is a consistent and reproducible distinction between “northern” and “southern” European population groups: most individual participants with southern European ancestry (Italian, Spanish, Portuguese, and Greek) have >85% membership in the “southern” population; and most northern, western, eastern, and central Europeans have >90% in the “northern” population group. Ashkenazi Jewish as well as Sephardic Jewish origin also showed >85% membership in the “southern” population, consistent with a later Mediterranean origin of these ethnic groups. Based on this work, we have developed a core set of informative SNP markers that can control for this partition in European population structure in a variety of clinical and genetic studies.

Allergic rhinitis (AR) is a common inflammation of the nasal mucosa in response to allergen exposure. We translated and validated the Score for Allergic Rhinitis (SFAR) into an Arabic version so that the disease can be studied in an Arabic population. SFAR is a non-invasive self-administered tool that evaluates eight items related to AR. This study aimed to translate and culturally adapt the SFAR questionnaire into Arabic, and assess the validity, consistency, and reliability of the translated version in an Arabic-speaking population of patients with suspected AR. Cross-sectional. Tertiary care hospital in Riyadh. The Arabic version of the SFAR was administered to patients with suspected AR and control participants. Comparison of the AR and control groups to determine the test-retest reliability and internal consistency of the instrument. The AR (n=173) and control (n=75) groups had significantly different Arabic SFAR scores (P < .0001). The instrument provided satisfactory internal consistency (Cronbach's alpha value of 0.7). The test-retest reliability was excellent for the total Arabic SFAR score (r =0.836, P < .0001). These findings demonstrate that the Arabic version of the SFAR is a valid tool that can be used to screen Arabic speakers with suspected AR. The absence of objective allergy testing.

The biological activities of tocotrienols are receiving increasing attention. Herein, we report the efficacy of a mixed-tocotrienol diet against prostate tumorigenesis in the transgenic adenocarcinoma mouse prostate (TRAMP) mouse model. Male TRAMP mice, 8 wk old, were fed 0.1%, 0.3%, or 1% mixed tocotrienols in AIN-76A diet up to 24 wk old. Likewise, a positive control group consisting of male TRAMP mice and a negative control group consisting of wild-type nontransgenic mice were fed regular AIN-76A diet up to 24 wk old. Our results show that mixed-tocotrienol-fed groups had a lower incidence of tumor formation along with a significant reduction in the average wet weight of genitourinary apparatus. Furthermore, mixed tocotrienols significantly reduced the levels of high-grade neoplastic lesions as compared to the positive controls. This decrease in levels of high-grade neoplastic lesions was found to be associated with increased expression of proapoptotic proteins BAD (Bcl2 antagonist of cell death) and cleaved caspase-3 and cell cycle regulatory proteins cyclin dependent kinase inhibitors p21 and p27. In contrast, the expression of cyclins A and E were found to be decreased in mixed-tocotrienol groups. Taken together, our results show that by modulating cell cycle regulatory proteins and increasing expression of proapoptotic proteins, mixed tocotrienols suppress prostate tumorigenesis in the TRAMP mice.

Heart rate variability biofeedback (HRV-BFB) has been shown as useful tool to manage stress in various populations. The present study was designed to investigate whether the biofeedback-based stress management tool consisting of rhythmic breathing, actively self-generated positive emotions and a portable biofeedback device induce changes in athletes' HRV, EEG patterns, and self-reported anxiety and self-esteem. The study involved 41 healthy male athletes, aged 16-21 (mean 18.34 ± 1.36) years. Participants were randomly divided into two groups: biofeedback and control. Athletes in the biofeedback group received HRV biofeedback training, athletes in the control group didn't receive any intervention. During the randomized controlled trial (days 0-21), the mean anxiety score declined significantly for the intervention group (change-4 p < 0.001) but not for the control group (p = 0.817). In addition, as compared to the control, athletes in biofeedback group showed substantial and statistically significant improvement in heart rate variability indices and changes in power spectra of both theta and alpha brain waves, and alpha asymmetry. These changes suggest better self-control in the central nervous system and better flexibility of the autonomic nervous system in the group that received biofeedback training. A HRV biofeedback-based stress management tool may be beneficial for stress reduction for young male athletes.

Mind-body training (MBT) may control reactions to stress and regulate the nervous and immune systems. The present study was designed to assess the effects of MBT on plasma cytokines and their interactions with catecholamines. The study group consisted of 80 subjects who practice MBT and a control group of 62 healthy subjects. Plasma catecholamine (norepinephrine, NE; epinephrine, E; and dopamine, DA) and cytokine (TNF-alpha, IL-6, IFN-gamma, and IL-10) levels were measured, and the differences between the MBT and control groups and the interactions of cytokines with catecholamines were investigated. A significant increase in IL-10+IFN-gamma was found in females of the MBT group compared with controls. Also, a significant increase of IL-10 (anti-inflammatory cytokine) in the MBT group was shown in a specific condition in which TNF-alpha and IL-6 (pro-inflammatory cytokines) are almost absent (≤1 ng/L) compared with controls. In the MBT group, significant positive correlations were found between IL-10 and the NE/E ratio and between IL-10 and the DA/E ratio, whereas the control group did not show any such correlations. MBT may increase IL-10, under specific conditions such as a decrease of pro-inflammatory cytokines or E, which may regulate the stress response and possibly contribute to effective and beneficial interactions between the nervous and immune systems.

A retrospective further analysis of the ACTION database evaluated the relationship between cardiovascular outcomes and the "quality" of the control of blood pressure (BP). The study population (n = 6287) comprised those patients with four BP measurements during year 1 subdivided according to the proportion of visits in which BP was controlled in relation to two BP targets: < 140/90mmHg and < 130/80 mmHg. Differences between the BP control groups for the major prespecified ACTION outcomes were investigated with Cox proportional hazards models. For all the prespecified cardiovascular endpoints the incidence declined as the proportion of visits with BP control increased. The greatest differences in outcomes between the different BP control groups were observed for the risk of stroke but were still apparent for all the other endpoints. For example, the risks for the primary outcome [hazard ratio (HR) 0.78; 95% confidence interval (CI) 0.67 to 0.90] were significantly less in the group with >_75% of visits with BP control than in the group with < 25% of visits with BP control. There were no significant treatment-related differences. Retrospective analyses are not definitive but these results highlight the importance of the attainment of BP control targets and the consistency of BP control during long-term follow-up.

M. Sechenov Moscow Medical Academy (n = 140) was assessed to evaluate the efficiency of using a dry protein composite formula in the package of therapeutic measures in inpatients with pulmonary tuberculosis. A study group included 200 patients whose basic diet comprised the dry protein composite formula DISOO Nutrinor. A control group consisted of 100 patients receiving standard antituberculosis treatment and basic diet without using the above formula. In the vast majority of study group patients (n = 152), intoxication symptoms substantially reduced 1.6 months after the start of treatment whereas this occurred noticeably later (following 2.5 months) in the control group (n = 80). Better positive changes in weight gain were found during dietary therapy with the dry protein composite formula in the study group than in the control group. During correction of a dietary protein component, the monthly body weight gain in the study group was 2.2 kg on average greater than that in the control group. The study group patients were also found to have a more significant resolution of infiltrative and focal lung changes on control X-ray studies than the control patients. Also, the study group patients showed a trend for more frequent cessation of bacterial excretion than did the controls. The rate of adverse reactions to chemotherapy was 5% (10 subjects) in the study group and thrice higher than that in the control group (15%, 15 subjects) in the control group. The findings prove the efficiency and urgency of correction of protein-energy deficiency in patients with active pulmonary tuberculosis, by supplementing the dry protein composite formula to the basic diet.

The aim of this study was to develop and measure the effect of a movie-based-nursing intervention program designed to enhance motivation for rehabilitation and reduce depression levels in stroke patients. The study used a quasi-experimental, nonequivalent control group and a pretest-posttest design. The 60 research subjects were assigned to the experimental (n=30) or control group (n=30). The moviebased nursing intervention program was provided for the experimental group during 60-minute sessions held once per week for 10 weeks. The program consisted of patient education to strengthen motivation for rehabilitation and reduce depression, watching movies to identify role models, and group discussion to facilitate therapeutic interaction. After 10 weeks of participation in the movie-based nursing intervention program, the experimental group's rehabilitation motivation score was significantly higher, F=1161.54 (within groups df=49, between groups df=1), p<.001, relative to that observed in the control group. In addition, the experimental group's depression score was significantly lower relative to that observed in the control group, F=258.97 (within groups df=49, between groups df=1), p<.001. The movie-based nursing intervention program could be used for stroke patients experiencing psychological difficulties including reduced motivation for rehabilitation and increased depression during the rehabilitation process. © 2017 Korean Society of Nursing Science

Depressive disorder was associated with dysfunctional self-regulation. The current study attempted to design and test a comprehensive self-control training (CSCT) program with an overall emphasis on behaviral activation in depressed Chinese college students. Participants included 74 students who had diagnosed with major depression, they were randomly assigned to one of the two groups: intervention group (n=37), and control group (n=37). The intervention participants received an eight-week CSCT and four-month follow-up consolidation program, as compared to the control group who received only pre-post-and-follow-up measurements. All participants measured Beck Depression Inventory (BDI-Ⅱ) and Self-control Scale (SCS) at three time points: baseline, post-training, and four-month follow-up. The dropout rates were 6 (8.1%) in the intervention group and 3 (4.1%) in the control group at the end of six-month intervention. The general linear model repeated measures analysis of variance revealed that comparing with the control group, the intervention group participants had more increase in their trait self-control score, at the meantime, their depressive symptoms had significantly improved. Univariate and logistic regression analyses revealed that participants with milder baseline depressive symptoms were more likely to benefit from CSCT interventions; depression improvement was also associated with the number of sessions attended. The main limitation was related to the small sample size which consisted of college students who were relatively young and well educated. The current study demonstrates that CSCT program could temporarily enhance self-control capacity as well as improve depressive symptoms; participants who are mildly to moderately depressed, and who could adhere to the training protocol are more likely to benefit from the intervention.

To evaluate possible contribution of maturational delay of brain stem in the etiology of breath-holding spells in children using brain stem auditory evoked potentials. The study group included children who experienced breath-holding spells. The control group consisted of healthy age- and sex-matched children. Age, gender, type and frequency of spell, hemoglobin, and ferritin levels in study group and brain stem auditory evoked potentials results in both groups were recorded. Study group was statistically compared with control group for brain stem auditory evoked potentials. The mean age of study and control groups was 26.3 ± 14.6 and 28.9 ± 13.9 months, respectively. The III-V and I-V interpeak latencies were significantly prolonged in the study group compared with the control group (2.07 ± 0.2 milliseconds; 1.92 ± 0.13 milliseconds and 4.00 ± 0.27 milliseconds; 3.83 ± 0.19 milliseconds; P = 0.009 and P = 0.03, respectively). At the same time, III-V and I-V interpeak latencies of patients without anemia in the study group compared with those of control group were significantly prolonged (2.09 ± 0.24 milliseconds; 1.92 ± 0.13 milliseconds and 4.04 ± 0.28 milliseconds; 3.83 ± 0.19 milliseconds; P = 0.007 and P = 0.01, respectively). Our results consider that maturational delay in myelination of brain stem may have a role in the etiology of breath-holding spells in children.

Flatfoot deformity is a lever arm disease that incurs kinetic inefficiency during gait. The purpose of this study was to measure the degree of kinetic inefficiency by comparing the gait analysis data of a flatfoot group with a normal control group. The patient group consisted of 26 children (21 males and 5 females) with symptomatic flatfoot. They were examined with gait analysis between May 2005 and February 2014. Exclusion criteria were patients with secondary flatfoot caused by neuromuscular disorders, tarsal coalition, vertical talus, or others. Patients' mean age was 9.5 years (range, 7 to 13 years). The gait analysis data of the study group and the normal control group were compared. The mean vertical ground reaction force (GRF) in the push-off phase was 0.99 for the patient group and 1.15 for the control group ( p < 0.05). The mean ankle moment in the sagittal plane during the push-off phase was 0.89 for the patient group and 1.27 for the control group ( p < 0.05). The mean ankle power in the sagittal plane during the push-off phase was 1.38 for the patient group and 2.52 for the control group ( p < 0.05). The aforementioned results show that patients with pes planovalgus had a reduction of moment, power, and GRF in the push-off phase during gait. Symptomatic flatfeet had a moment inefficiency of 30% and power inefficiency of 45% during gait compared to feet with preserved medial longitudinal arches.

Background: This study aimed to compare the effects of the schema along with mindfulness-based therapies in the psoriasis patients. Materials and Methods: This semi-experimental study with post- and pre-tests was conducted on the psoriasis patients in the Dermatology Clinic of the Isfahan Alzahra Hospital, Iran using the convenience sampling in 2014. The patients had a low general health score. The experimental groups included two treatment groups of schema-based (n = 8) and mindfulness (n = 8). Both groups received eight 90-min sessions therapy once a week; they were compared with 8 patients in the control group. To evaluate the psoriasis patients’ maladaptive schema, Young schema questionnaire was used. Data were analyzed through the covariance analysis test. Results: There was a significant difference between the schema-based therapy and mindfulness groups with the control group. There was also a significant difference between the schema-based therapy groups consisting of the defeated schema, dependence/incompetence schema, devotion schema, stubbornly criteria schema, merit schema, restraint/inadequate self-discipline schema, and the control group. Moreover, a significant difference existed between the maladaptive schema of mindfulness therapy group and the controls. There was a significant difference concerning the improvement of the psychopathologic symptoms between the mindfulness therapy group and the control group. Conclusions: This study showed similar effects of both the schema and mindfulness-based therapies on the maladaptive schemas in improving the psoriasis patients with the psychopathologic symptoms.

Unbalanced 2 x 2 Factorial Designs and the Interaction Effect: A Troublesome Combination

PubMed Central

2015-01-01

In this power study, ANOVAs of unbalanced and balanced 2 x 2 datasets are compared (N = 120). Datasets are created under the assumption that H1 of the effects is true. The effects are constructed in two ways, assuming: 1. contributions to the effects solely in the treatment groups; 2. contrasting contributions in treatment and control groups. The main question is whether the two ANOVA correction methods for imbalance (applying Sums of Squares Type II or III; SS II or SS III) offer satisfactory power in the presence of an interaction. Overall, SS II showed higher power, but results varied strongly. When compared to a balanced dataset, for some unbalanced datasets the rejection rate of H0 of main effects was undesirably higher. SS III showed consistently somewhat lower power. When the effects were constructed with equal contributions from control and treatment groups, the interaction could be re-estimated satisfactorily. When an interaction was present, SS III led consistently to somewhat lower rejection rates of H0 of main effects, compared to the rejection rates found in equivalent balanced datasets, while SS II produced strongly varying results. In data constructed with only effects in the treatment groups and no effects in the control groups, the H0 of moderate and strong interaction effects was often not rejected and SS II seemed applicable. Even then, SS III provided slightly better results when a true interaction was present. ANOVA allowed not always for a satisfactory re-estimation of the unique interaction effect. Yet, SS II worked better only when an interaction effect could be excluded, whereas SS III results were just marginally worse in that case. Overall, SS III provided consistently 1 to 5% lower rejection rates of H0 in comparison with analyses of balanced datasets, while results of SS II varied too widely for general application.

The Sensory Perception Quotient (SPQ): development and validation of a new sensory questionnaire for adults with and without autism

PubMed Central

2014-01-01

Background Questionnaire-based studies suggest atypical sensory perception in over 90% of individuals with autism spectrum conditions (ASC). Sensory questionnaire-based studies in ASC mainly record parental reports of their child’s sensory experience; less is known about sensory reactivity in adults with ASC. Given the DSM-5 criteria for ASC now include sensory reactivity, there is a need for an adult questionnaire investigating basic sensory functioning. We aimed to develop and validate the Sensory Perception Quotient (SPQ), which assesses basic sensory hyper- and hyposensitivity across all five modalities. Methods A total of 359 adults with (n = 196) and without (n = 163) ASC were asked to fill in the SPQ, the Sensory Over-Responsivity Inventory (SensOR) and the Autism-Spectrum Quotient (AQ) online. Results Adults with ASC reported more sensory hypersensitivity on the SPQ compared to controls (P < .001). SPQ scores were correlated with AQ scores both across groups (r = .-38) and within the ASC (r = -.18) and control groups (r = -.15). Principal component analyses conducted separately in both groups indicated that one factor comprising 35 items consistently assesses sensory hypersensitivity. The SPQ showed high internal consistency for both the total SPQ (Cronbach’s alpha = .92) and the reduced 35-item version (alpha = .93). The SPQ was significantly correlated with the SensOR across groups (r = -.46) and within the ASC (r = -.49) and control group (r = -.21). Conclusions The SPQ shows good internal consistency and concurrent validity and differentiates between adults with and without ASC. Adults with ASC report more sensitivity to sensory stimuli on the SPQ. Finally, greater sensory sensitivity is associated with more autistic traits. The SPQ provides a new tool to measure individual differences on this dimension. PMID:24791196

Direct ophthalmoscopy is an important clinical skill that is often poorly performed by medical professionals and students. This is attributable to a declining emphasis on ophthalmology in medical school. We present and evaluate a self-directed approach of teaching ophthalmoscopy to medical students that is suitable for the current medical curriculum. Prospective medical education trial. Ninety-five second-year medical students at Queen's University: 32 in the experimental group and 63 in the control group. The experimental group consisted of medical students who practised ophthalmoscopy with one another using an online peer fundus photograph matching exercise created by the Department of Ophthalmology at Queen's University. To use the program, students first examined a peer with an ophthalmoscope and then selected an online photograph of a fundus corresponding to that of the examinee. The program notifies students if a correct selection is made. To encourage use of the program, students participated in a 2-week ophthalmoscopy competition during their ophthalmology rotation. The control group consisted of students who did not participate in the learning exercise. On assessment at the end of the ophthalmology rotation, the experimental group (n = 32) was more accurate in matching fundus photographs compared with the control group (n = 63) (p = 0.02). Participants were faster at performing ophthalmoscopy at the end of the learning exercise (p < 0.01). All students in the experimental group reported increased confidence levels in ophthalmoscopy after participation in the learning exercise. Matching online peer fundus photographs in a self-directed manner appeared to increase the skill and confidence of medical students in ophthalmoscopy.

Objectives: Was to evaluate the effect of different regional anesthetics (articaine with epinephrine versus prilocaine with felypressin) on stress in the extraction of impacted lower third molars in healthy subjects. Sutdy Desing: A prospective single-blind, split-mouth cross-over randomized study was designed, with a control group. The experimental group consisted of 24 otherwise healthy male volunteers, with two impacted lower third molars which were surgically extracted after inferior alveolar nerve block (regional anesthesia), with a fortnight’s interval: the right using 4% articaine with 1:100.000 epinephrine, and the left 3% prilocaine with 1:1.850.000 felypressin. Patients were randomized for the first surgical procedure. To analyze the variation in four stress markers, homovanillic acid, 3-methoxy-4-hydroxyphenylglycol, prolactin and cortisol, 10-mL blood samples were obtained at t = 0, 5, 60, and 120 minutes. The control group consisted of 12 healthy volunteers, who did not undergo either extractions or anesthetic procedures but from whom blood samples were collected and analyzed in the same way. Results: Plasma cortisol increased in the experimental group (multiple range test, P<0.05), the levels being significantly higher in the group receiving 3% prilocaine with 1:1.850,000 felypressin (signed rank test, p<0.0007). There was a significant reduction in homovanillic acid over time in both groups (multiple range test, P<0.05). No significant differences were observed in homovanillic acid, 3-methoxy-4-hydroxyphenylglycol or prolactin concentrations between the experimental and control groups. Conclusions: The effect of regional anesthesia on stress is lower when 4% articaine with 1:100,000 epinephrine is used in this surgical procedure. Key words:Stress markets, epinephrine versus felypressin. PMID:24316704

To evaluate the prostate cancer effects of androgen deprivation therapy (ADT) by using a systematic set of methods to calculate specific cognitive functions in men with locally advanced or metastatic prostate cancer. From April 2014 to February 2016, a prospective, comparative study was done to evaluate the cognitive effects of hormone therapy. Group 1 consisted of 78 patients with locally advanced or metastatic prostate cancer who received complete ADT treatment continuously for 12 months and group 2 (control group) consisted of 78 patients who underwent radical prostatectomy without any additional treatment. The Montreal Cognitive Assessment (MoCA) test and the Frontal Assessment Battery (FAB) test with Turkish language version were used to evaluate multiple domains of cognitive function. Post-treatment results of both tests revealed that patients in group 1 achieved lower mean total scores than group 2. In MoCA test, the deficits were especially prominent in the areas of language ability and short-term memory capacity (P < .05 and P < .05). No significant differences could be identified between groups in respect to attention, executive functions, visuospatial abilities, abstract thinking, calculating abilities, and orientation. In FAB test, the deficits were especially prominent in the areas of mental flexibility and inhibitory control (P < .05 and P < .05). No significant differences could be identified between groups in conceptualization, motor series, conflicting instructions, and environmental autonomy. ADT affects cognitive functions such as language ability, short-term memory capacity, mental flexibility, and inhibitory control. Urologists should keep in mind these side effects and inform the patients and their families for the early symptoms of cognitive dysfunction. Copyright © 2017 Elsevier Inc. All rights reserved.

To evaluate and compare the uniformity of angle Kappa adjustment between Oculyzer and Topolyzer Vario topography guided ablation of laser in situ keratomileusis (LASIK) by EX500 excimer laser for myopia. Totally 145 cases (290 consecutive eyes )with myopia received LASIK with a target of emmetropia. The ablation for 86 cases (172 eyes) was guided manually based on Oculyzer topography (study group), while the ablation for 59 cases (118 eyes) was guided automatically by Topolyzer Vario topography (control group). Measurement of adjustment values included data respectively in horizontal and vertical direction of cornea. Horizontally, synclastic adjustment between manually actual values (dx manu ) and Oculyzer topography guided data (dx ocu ) accounts 35.5% in study group, with mean dx manu /dx ocu of 0.78±0.48; while in control group, synclastic adjustment between automatically actual values (dx auto ) and Oculyzer topography data (dx ocu ) accounts 54.2%, with mean dx auto /dx ocu of 0.79±0.66. Vertically, synclastic adjustment between dy manu and dy ocu accounts 55.2% in study group, with mean dy manu /dy ocu of 0.61±0.42; while in control group, synclastic adjustment between dy auto and dy ocu accounts 66.1%, with mean dy auto /dy ocu of 0.66±0.65. There was no statistically significant difference in ratio of actual values/Oculyzer topography guided data in horizontal and vertical direction between two groups ( P =0.951, 0.621). There is high consistency in angle Kappa adjustment guided manually by Oculyzer and guided automatically by Topolyzer Vario topography during corneal refractive surgery by WaveLight EX500 excimer laser.

Due to large and increasing numbers of cancer survivors, long-term cancer-related health issues have become a major focus of attention. This study examined the relation between a high-intensity physical rehabilitation program and return-to-work in cancer survivors who had received chemotherapy. The intervention group, consisting of 72 cancer survivors from one hospital (8 men and 64 women, mean age 49 years), followed an 18-weeks rehabilitation program including strength and interval training, and home-based activities. An age-matched control group, consisting of 38 cancer survivors (9 men and 29 women), was recruited from two other hospitals. They received only standard medical care. All subjects were evaluated during a telephone interview on employment issues, conducted at ±3 years after diagnosis. The main outcomes were change in working hours per week and time until return-to-work. Patients in the intervention group showed significant less reduction in working hours per week [-5.0 h/week vs. -10.8 h/week (P = .03)]. Multivariate analyses showed that the training intervention, the age of patients, and the number of working hours pre-diagnosis could explain the improvement in long-term participation at work. Time until (partial) return-to-work was 11.5 weeks for the intervention group versus 13.2 weeks for the control group (P = .40). On long-term follow-up, 78% of the participants from the intervention group versus 66% from the control group had returned to work on the pre-diagnosis level of working hours (P = .18). Rehabilitation using high-intensity physical training is useful for working patients to minimize the decreased ability to work resulting from cancer and its treatment.

To compare functional changes and cortical neuroplasticity associated with hand and upper extremity use after massed (repetitive task-oriented practice) training, somatosensory stimulation, massed practice training combined with somatosensory stimulation, or no intervention, in persons with chronic incomplete tetraplegia. Participants were randomly assigned to 1 of 4 groups: massed practice training combined with somatosensory peripheral nerve stimulation (MP+SS), somatosensory peripheral nerve stimulation only (SS), massed practice training only (MP), and no intervention (control). University medical school setting. Twenty-four subjects with chronic incomplete tetraplegia. Intervention sessions were 2 hours per session, 5 days a week for 3 weeks. Massed practice training consisted of repetitive practice of functional tasks requiring skilled hand and upper-extremity use. Somatosensory stimulation consisted of median nerve stimulation with intensity set below motor threshold. Pre- and post-testing assessed changes in functional hand use (Jebsen-Taylor Hand Function Test), functional upper-extremity use (Wolf Motor Function Test), pinch grip strength (key pinch force), sensory function (monofilament testing), and changes in cortical excitation (motor evoked potential threshold). The 3 groups showed significant improvements in hand function after training. The MP+SS and SS groups had significant improvements in upper-extremity function and pinch strength compared with the control group, but only the MP+SS group had a significant change in sensory scores compared with the control group. The MP+SS and MP groups had greater change in threshold measures of cortical excitability. People with chronic incomplete tetraplegia obtain functional benefits from massed practice of task-oriented skills. Somatosensory stimulation appears to be a valuable adjunct to training programs designed to improve hand and upper-extremity function in these subjects.

OBJECTIVE: To evaluate an educational program for family medicine residents on using selected inhaler devices for delivery of asthma medications. DESIGN: A prospective analysis using pretests and posttests of a nonrandomized study group and control group. The study group of residents was given an instructional manual and a set of devices for home study, followed by a 1-hour tutorial session with a clinical instructor that included a video and hands-on practice. SETTING: Family medicine centres in Edmonton hospitals. PARTICIPANTS: The study group consisted of a convenience sample of 23 first- and second-year family medicine residents at the Misericordia Hospital Family Medicine Centre. The control group consisted of a convenience sample of 22 first- and second-year family medicine residents at the Royal Alexandra Hospital Family Medicine Centre. Nine residents did not take the posttest; one was absent because of injury, one missed the in-service, and seven had left the city on other rotations, had completed their program, or declined to participate. MAIN OUTCOME MEASURES: Improvements in scores on a multiple-choice test and in techniques of using the devices. RESULTS: Using an average of scores on seven different devices, only 36% of residents showed adequate knowledge of how to use the devices on the pretest. Posttest scores improved for both the control (P < 0.001) and study (P < 0.001) groups, but improvement was significantly greater for the study group (P < 0.001). CONCLUSIONS: Residents lacked adequate knowledge of asthma devices. More study is needed to confirm the long-term effectiveness of formal teaching about the devices. Images Figure 1 PMID:7888821

We compared the mediolateral (M/L) responses to perturbations during locomotion of vestibulopathic (VP) subjects to those of controls. Eight subjects with unilateral vestibular loss (100% Reduced Vestibular Response from the caloric test) resulting from surgery for vestibular schwannoma and 11 controls were selected for this study. Despite their known vestibulopathy, all VP subjects scored within the normal range on computerized dynamic posturography Sensory Organization Tests. During gait, subjects were given surface perturbations of the right support-phase foot in two possible directions (forward-right and backward-left) at two possible magnitudes (5 and 10 cm) that were randomly mixed with trials having no perturbations. M/L stability was quantified by estimating the length of the M/L moment arm between the support foot and the trunk, and the M/L accelerations of the sternum and the head. The VP group had greater changes (p < 0.05) in their moment arm responses compared to controls. The number of steps that it took for the moment arm oscillations to return to normal and the variability in the moment arms were greater for the VP group. Differences in the sternum and head accelerations between VP and control groups were not as consistent, but there was a trend toward greater response deviations in the VP group for all 4 perturbation types. Increased response magnitude and variability of the VP group is consistent with an increase in their sensory noise of vestibular inputs due to the surgical lesion. Another possibility is a reduced sensitivity to motion inputs. This perturbation approach may prove useful for characterizing subtle vestibulopathies and similar changes in the human orientation mechanism after exposure to microgravity.

The aim of this study was to investigate the short- and long-term effects induced by rapid maxillary expansion (RME) on the shape of the maxillary and circummaxillary structures by means of thin-plate spline (TPS) analysis. The sample consisted of 42 patients who were compared with a control sample of 20 subjects. The treated subjects underwent Haas-type RME, followed by fixed appliance therapy. Postero-anterior (PA) cephalograms were analysed for each treated subject at T1 (pre-treatment), T2 (immediate post-expansion), and T3 (long-term observation), and were available at T1 and T3 for the control group (CG). The mean age at T1 was 11 years and 10 months for both groups. The mean chronological ages at T3 were 20 years, 6 months for the treated group (TG) and 17 years, 8 months for the control group. The study focused on shape changes in the maxillary, nasal, zygomatic, and orbital regions. TPS analysis revealed significant shape changes in the TG. They consisted of an upward and lateral displacement of the two halves of the naso-maxillary complex as a result of active expansion in the short-term, and normalization of maxillary shape in the transverse dimension in the long-term (the initial transverse deficiency of the maxilla in the treated group was eliminated by RME therapy both in the short- and long-term). At the end of the observation period, the nasal cavities were larger when compared with both their pre-expansion configuration and the final configuration in the controls. RME with the Haas appliance appears to be an efficient therapeutic means to induce permanent favourable changes in the shape of the naso-maxillary complex.

Tobacco control in Colombia is regulated by Law 1335 of 2009. The implementation and monitoring of the provisions of this law require strengthening of intersectorial work at the local level. This field note presents an intersectorial work experience that was carried out in the municipality of Tunja (Colombia) to improve tobacco control. The Respirarte Group was established. This group consists of an intersectorial team composed of 15 institutions. The Respirarte Group achieved the following political and community actions: signing of an agreement on tobacco control by government actors, expedition of a local decree to comply with Law 1335 in the municipality, provision of information and communication, and social mobilization and monitoring. This experience serves as a national and international reference and its lessons could be used in the approach to other public health problems. Copyright © 2014 SESPAS. Published by Elsevier Espana.

Numerous studies have shown an association between patent foramen ovale (PFO) and cryptogenic stroke suggesting that paradoxical emboli may be an important cause of stroke. In addition, some authors have proposed that platelet activation is present in PFO patients and this might be the cause of the stroke. The aim of this study was to assess the mean platelet volume (MPV), an indicator of platelet activation and/or reactivity in patients with PFO. The study group consisted of 77 patients with PFO. An age, sex, BMI-matched control group was composed of 43 healthy volunteers. We measured serum MPV values in patients and controls. MPV was significantly higher among PFO patients when compared with control group (9.0±0.8 vs. 8.3±0.9 fl, respectively; P<0.001). We have shown that MPV was significantly elevated in patients with PFO compared with controls.

There is growing interest in autism spectrum disorders (asd) in adulthood. Someone can be diagnosed with ASD, but the diagnosis tells us very little about the patient’s temperament, character and personality. Comparatively little is known about the personality traits of persons with ASD. To map personality traits of persons with asd. The Temperament and Character Inventory (tci) was administered to a group of 68 men diagnosed with asd at the Lucertis Sarr expertise centre for Autism and at the Department of Psychiatry, Erasmus mc, Rotterdam, the Netherlands. The control group, specified in the instructions for the tci, consisted of a group of 447 men from the general population. Compared to the control group, men with asd scored higher on the scale Harm Avoidance, but lower on Sociability, Novelty Seeking, Reward Dependence, Self-directedness, and Cooperativeness. The score pattern found in men with asd is consistent with the clinical picture of asd and corresponds to earlier results of research done in Sweden. In our study we argue that negatively interpreted temperament and character traits can often be interpreted in a positive way.

To test the efficacy of a single-session, clinic-based intervention designed to promote condom use among young black men who have sex with men (YBMSM). Six hundred YBMSM were enrolled in a randomized controlled trial, using a 12-month observation period. An intent-to-treat analysis was performed, with multiple imputation for missing data. Compared with the reference group, human immunodeficiency virus (HIV)-infected men in the intervention group had 64% greater odds of reporting consistent condom use for anal receptive sex over 12 months (estimated odds ratio, 1.64; 95% confidence interval, 1.23-2.17, P = 0.001). Also, compared with the reference group, HIV-uninfected men in the intervention group had more than twice the odds of reporting consistent condom use for anal receptive sex over 12 months (estimated odds ratio, 2.14; 95% confidence interval, 1.74-2.63, P < 0.001). Significant intervention effects relative to incident sexually transmitted diseases were not observed. A single-session, clinic-based, intervention may help protect HIV-uninfected YBMSM against HIV acquisition and HIV-infected YBMSM from transmitting the virus to insertive partners.

Introduction The aim of the study was to assess the correlation between the oral health status, oral health related quality of life and the evaluations of their smiles as assessed by the children, their parents, and through measurements of the children’s videotaped smiles and compare the smiling patterns in children suffering from untreated traumatic injuries to anterior teeth and control group. Materials and Methods Fifty eight children of the age 5–15 years of both sexes were selected for the study and categorized into experimental group and control group. The experimental group consisted of 29 children with untreated trauma to one or more anterior teeth while the control group consisted of 29 children with good oral health. Oral examination of all children was done to include in study groups. Children and parents participating in the study responded to two separate Oral Health Related Quality of Life questionnaires for children and parents respectively. The children were asked to watch a funny cartoon show and a video was made while the children watched the show. The video was cropped into still images at 25 predetermined points. Width and openness of the children’s mouth and number of teeth shown were measured during the taped sessions to assess the children’s video–based smiling patterns. Results The children’s self evaluation scores had statistically significant correlation with their smiling patterns, the number of traumatized teeth and the parental assessment of their children’s oral health. Children with trauma to anterior teeth had more impacts on their smiling pattern compared to control group. Conclusion Children suffering from trauma to anterior teeth had more effects on the emotions, the self confidence and social interaction than children without any traumatic injury. PMID:26266209

Diabetes Mellitus is a condition that predisposes a higher risk for the development of osteoporosis. The objective of this study was to investigate the influence of boron supplementation on bone microstructure and strength in control and non-obese diabetic mice for 30days. The animals were supplemented with 40μg/0,5ml of boron solution and controls received 0,5ml of distilled water daily. We evaluated the biochemical parameters: total calcium, phosphorus, magnesium and boron; bone analysis: bone computed microtomography, and biomechanical assay with a three point test on the femur. This study consisted of 28 animals divided into four groups: Group water control - Ctrl (n=10), Group boron control - Ctrl±B (n=8), Group diabetic water - Diab (n=5) and Group diabetic boron - Diab±B (n=5). The results showed that cortical bone volume and the trabecular bone volume fraction were higher for Diab±B and Ctrl±B compared to the Diab and Ctrl groups (p≤0,05). The trabecular specific bone surface was greater for the Diab±B group, and the trabecular thickness and structure model index had the worst values for the Diab group. The boron serum concentrations were higher for the Diab±B group compared to non-supplemented groups. The magnesium concentration was lower for Diab and Diab±B compared with controls. The biomechanical test on the femur revealed maintenance of parameters of the bone strength in animals Diab±B compared to the Diab group and controls. The results suggest that boron supplementation improves parameters related to bone strength and microstructure of cortical and trabecular bone in diabetic animals and the controls that were supplemented.

2017-11-01

The aim of this study was to evaluate anatomic properties of the lens capsule and iris by anterior segment optical coherence tomography (AS-OCT) in patients with pseudoexfoliation (PEX). This prospective study included 62 eyes of 62 patients with PEX syndrome and 43 eyes of 43 age- and gender-matched controls. All subjects underwent full ophthalmologic examinations including AS-OCT. Pupillary diameter, midperipheral stromal iris thickness, central and temporal lens capsule thicknesses, and peripheral pseudoexfoliation material thickness on the anterior lens capsule surface were measured and recorded. Mean age was 66.8 ± 9.3 years in the PEX group and 65.5 ± 8.9 years in the control group (p = 0.44). The PEX group consisted of 62 patients: 38 men (61.3%) and 24 women (38.7%); the control group included 43 subjects: 25 men (58.1%) and 18 women (41.9%). Pupillary diameter after pharmacologic mydriasis was 21% smaller in the PEX group than controls. Mean midperipheral iris thickness was 36 ± 7.2 μm (7.8%) thinner in the PEX group than that of control group (p = 0.047). The central anterior capsule was a mean of 3.40 ± 0.51 μm (18%) thicker in the PEX group compared to the control group (p = 0.0001). The temporal anterior lens capsule was a mean of 0.17 ± 0.15 μm thicker in the PEX group compared to the control group (p = 0.81). With high-resolution OCT imaging, it has become possible to evaluate the anterior lens capsule without histologic examination and demonstrate that it is thicker than normal in PEX patients.

Intermittent photic stimulation (IPS) is an activation procedure used during electroencephalogram (EEG) recording to elicit paroxysmal discharges in individuals with photosensitivity. Specific responses on EEG recording may be provoked by IPS at different frequencies of flickering in normal individuals and in patients with photosensitive epilepsy. Changes in regional cerebral blood flow (rCBF) were studied during IPS in two groups of subjects by using [15O]-water positron emission tomography (PET): a control group consisting of eight healthy adults with photic driving response during IPS on EEG recording (mean age, 25 +/- 10.5 years) without history of neurologic or psychiatric abnormalities and a patient group consisting of four adults (mean age, 33 +/- 7.5 years) with history of photosensitive epilepsy. [15O]-water PET scanning with concomitant EEG monitoring was performed during baseline and IPS at 4-, 14-, and 30-Hz frequencies. The control group showed photic driving response at 14-Hz IPS frequency. The patient group showed photoparoxysmal response at 14 and 30 Hz, but not at 4 Hz. Changes in rCBF were determined by means of statistical parametric mapping. Increases in rCBF in occipital cortex (Brodmann's areas 17, 18, and 19) were observed in both groups. In addition, during photic driving responses, the control group showed rCBF increases in the insula and in the thalamus, on the right side. The patient group showed a significant rCBF increase in the hypothalamic region inferior to the left caudate nucleus during photoparoxysmal response. This activation was not found in the control group. Increased rCBF also was observed in the patient group in the head of the left caudate nucleus, in the left hippocampus, and in left insula during IPS without photoparoxysmal response. No activations in these regions were observed during photoparoxysmal response. These data may indicate involvement of the hypothalamus in photosensitive epilepsy and may suggest a modulatory function of the caudate nucleus, which might be associated with an inhibition of epileptic discharges during IPS in patients with photosensitive epilepsy.

The purpose of the present study was to investigate whether the floating form of the restricted environmental stimulation technique (REST) may be applied within the field of pain relief. Flotation-REST consists of a procedure whereby an individual is immersed in a tank filled with water of an extremely high salt concentration. Thirty-seven patients (14 men and 23 women) suffering from chronic pain consisting of aching muscles in the neck and back area participated in the study. They were randomly assigned to either a control group (17 participants) or an experimental group (20 participants). The experimental group received nine opportunities to use the flotation-REST technique in the water tank over a three-week period. The results indicated that the most severe perceived pain intensity was significantly reduced, whereas low perceived pain intensity was not influenced by the floating technique. Further, the results indicated that circulating levels of the noradrenaline metabolite 3-methoxy-4-hydroxyphenylethyleneglycol were reduced significantly in the experimental group but not in the control group following treatment, whereas endorphin levels were not affected by flotation. Flotation-REST treatment also elevated the participants' optimism and reduced the degree of anxiety or depression; at nighttime, patients who underwent flotation fell asleep more easily. The present findings describe possible changes, for the better, in patients presenting with chronic pain complaints.

Motion perception without Nystagmus--a novel manifestation of cerebellar stroke.

PubMed

Shaikh, Aasef G

2014-01-01

The motion perception and the vestibulo-ocular reflex (VOR) each serve distinct functions. The VOR keeps the gaze steady on the target of interest, whereas vestibular perception serves a number of tasks, including awareness of self-motion and orientation in space. VOR and motion perception might abide the same neurophysiological principles, but their distinct anatomical correlates were proposed. In patients with cerebellar stroke in distribution of medial division of posterior inferior cerebellar artery, we asked whether specific location of the focal lesion in vestibulocerebellum could cause impaired perception of motion but normal eye movements. Thirteen patients were studied, 5 consistently perceived spinning of surrounding environment (vertigo), but the eye movements were normal. This group was called "disease model." Remaining 8 patients were also symptomatic for vertigo, but they had spontaneous nystagmus. The latter group was called "disease control." Magnetic resonance imaging in both groups consistently revealed focal cerebellar infarct affecting posterior cerebellar vermis (lobule IX). In the "disease model" group, only part of lobule IX was affected. In the disease control group, however, complete lobule IX was involved. This study discovered a novel presentation of cerebellar stroke where only motion perception was affected, but there was an absence of objective neurologic signs.

This study investigates the treatment of non-alcoholic fatty liver disease (NAFLD) in rats with choline and fructooligosaccharide (FOS). The healthy control group received standard diet. The other three groups consisted of animals with NAFLD. Group Estr received standard diet; group Echo received standard diet plus choline (3 g/100 g diet); and group Efos received standard diet plus FOS (10 g/100 g diet). Food intake, weight, urinary nitrogen, urinary ammonia, total cholesterol, serum triacylglyceride, liver and heart weights, tissue nitrogen, tissue fat, vitamin E, TBARS, and reduced glutathione (GSH) were measured in hepatic and heart tissue. Choline and FOS treatments resulted in total mean fat reduction in liver and heart tissue of 0.2 and 1.7 g, respectively. Both treatments were equally effective in reducing hepatic and cardiac steatosis. There were no differences in the TBARS level among experimental and control groups, indicating that the proposed treatments had no added protection against free radicals. While all experimental groups had increased vitamin E and GSH levels, choline treatment led to a significant increase compared to control. PMID:25987847

To determine whether or not a previous abortion has a deleterious effect on the outcome of a subsequent pregnancy, 6443 delivery records at Ramathibodi hospital between January and December 1982 were reviewed. The 2 study groups consisted of 143 women who had previously had an induced abortion and 315 women who had previously had a spontaneous abortion. Control groups were women having a 2nd child after a normal 1st pregnancy. The 1st study group had fewer women under 19 and over 35 and a lower educational level. Group 2 had more women with a pregnancy interval of less than 2 years. There was no difference between the study groups and the controls in premature rupture of fetal membranes, placenta previa, cesarean sections, manual removal of placenta, retained secundine, postpartum hemorrhage, low birth weight, Apgar score less than 6, congenital abnormalities, or perinatal mortality. The only difference between both study groups and the controls was that there was a higher percentage of assisted deliveries in both study groups. This finding is probably the result of the fact that these were 1st births and is totally unrelated to previous abortion.

A quasi-experimental design with a nonequivalent control group was utilized. The Postpartum Care Center of Women's Hospital in Gwangju City, Republic of Korea. The study group consisted of 39 postpartum women, 19 in the experimental group and 20 in the control group, recruited from the postpartum care center of Women's Hospital in Gwangju city, South Korea. The experimental group was provided with meridian acupressure massage for 90 min daily over 5 days as an experimental therapy. Body composition (body weight, BMI, total body water, ECW ratio, LBM, and body fat) Edema (subjective edema, average girth of the upper limbs, and average girth of the lower limbs), Stress (psychological stress and physical stress), and Fatigue. The experimental group demonstrated a significantly larger decrease compared with the control group in measures of body composition, edema, total subjective stress, psychological stress, and subjective fatigue. Meridian acupressure massage can hasten the return to original body composition after childbirth.

A cross-national trial of brief interventions with heavy drinkers. WHO Brief Intervention Study Group.

PubMed Central

1996-01-01

OBJECTIVES. The relative effects of simple advice and brief counseling were evaluated with heavy drinkers identified in primary care and other health settings in eight countries. METHODS. Subjects (1260 men, 299 women) with no prior history of alcohol dependence were selected if they consumed alcohol with sufficient frequency or intensity to be considered at risk of alcohol-related problems. Subjects were randomly assigned to a control group, a simple advice group, or a group receiving brief counseling. Seventy-five percent of subjects were evaluated 9 months later. RESULTS. Male patients exposed to the interventions reported approximately 17% lower average daily alcohol consumption than those in the control group. Reductions in the intensity of drinking were approximately 10%. For women, significant reductions were observed in both the control and the intervention groups. Five minutes of simple advice were as effective as 20 minutes of brief counseling. CONCLUSIONS. Brief interventions are consistently robust across health care settings and sociocultural groups and can make a significant contribution to the secondary prevention of alcohol-related problems if they are widely used in primary care.

An educational intervention to promote breast self-examinations (BSEs) among young women was tested. In a group (intervention versus control) x time (Session 1 versus Session 2) mixed design, 172 college females were randomly assigned to either an intervention or control condition. Both groups attended two sessions; the second session was 48 hours after the first. The intervention consisted of an essay, lecture, video portraying young survivors of breast cancer, group discussions, self-test and instructions on performing BSEs. The control group had the same format; however, the information was focused on nutrition and exercise. Participants in the intervention group scored higher on rational problem solving and behavioral intentions, suggesting that the intervention increased adaptive responses to breast cancer threat. Conversely, control participants scored significantly higher on maladaptive reactions (e.g. hopelessness, avoidance and fatalistic religiosity) to breast cancer threat. For intervention participants, the initial decline in maladaptive reactions remained stable at 3-month follow-up, but adaptive reactions decreased. Intervention participants had greater confidence in performing BSEs compared with controls but performed them on an irregular basis. Results were interpreted in terms of protection motivation theory, a model that applies the social psychology of persuasion to preventive health.

Strokes are caused by disruption of the blood supply to the brain. This may result from either blockage or rupture of a blood vessel. Yearly 15 million people worldwide suffer a stroke. India ranks second worldwide in terms of deaths from stroke. The incidence of stroke increases with age affecting the economically productive middle aged population. Hypertension and male sex are other risk factors for stroke. C-Reactive Protein (CRP) is an acute phase protein whose concentration rises in blood following inflammation. Formerly, assays for CRP detected its rise only after significant inflammation. However, recently developed high sensitivity assays (hsCRP) enable the measurement of CRP in individuals who are apparently healthy. Several studies indicate that hsCRP is elevated in individuals who are at risk of developing Coronary Artery Disease or Cerebrovascular events, the elevation may be found years before the first detection of vascular problems. In the absence of other biochemical markers, the present study aimed to evaluate the predictive and diagnostic role of hsCRP in stroke. The study consisted of 50 patients of acute stroke admitted in Gauhati Medical College and Hospital. The control population consisted of two groups - 50 age and sex matched controls with hypertension (Hypertensive control group) and 50 age and sex matched controls with no obvious disease constituted the Normal control group. hsCRP levels were measured in all the groups and compared statistically. hsCRP is an acute phase reactant whose concentration rises in stroke as well as in those at risk. The rise may be identified even before the appearance of risk factors. Hence, hsCRP may be useful as a predictive and diagnostic marker in stroke.

The Th1/Th 2 concept is a model to understand the pathophysiology of certain diseases. Atopic diseases (asthma, eczema and hayfever) are characterized by a chronic inflammatory reaction that is dominated by Th 2 cells, and type 1 diabetes mellitus (DM) is Th1 cell dominated. Because it is known that Th1 and Th 2 cells reciprocally counteract each other, it can be speculated that the prevalence of Th 2-mediated disease is lower in patients with Th1-mediated disease. To compare the prevalence of atopic diseases between children with DM and age-matched controls. Parents of children with DM were requested by Dutch paediatricians to complete the International Study of Asthma and Allergies in Childhood (ISAAC) questionnaire on the prevalence of atopic diseases. A control group was derived from a Dutch cross-sectional survey (the ISAAC2 study). We received 555 completed questionnaires, which is estimated to be 25% of the total number of Dutch children with DM. The control group consisted of 777 children. After age-matching, the questionnaires of 188 DM patients were used. Symptoms of asthma, hayfever and eczema were reported less in the group of children with DM compared with the control group (wheeze last year, OR 0.796, 95% CI 0.408-1.554; hayfever symptoms last year, OR 0.642, 95% CI 0.369-1.118; eczema symptoms last year, OR 0.693, 95% CI 0.430-1.115). The lower prevalence of astma, hayfever and eczema symptoms in DM patients compared with age-matched controls, although not statistically significant, is consistent with the Th1/Th 2 concept.

Chitotriosidase is an enzyme secreted by activated macrophages. This study aims to investigate the usefulness of circulating chitotriosidase activity as a marker of inflammatory status in patients with critical limb ischemia (CLI). An observational gender-matched case-control study was conducted on patients hospitalized with the primary diagnosis of CLI, as well as a control group. The control group consisted of healthy volunteers. Forty-three patients were included in each group. Similar demographic characteristics (median age of 60-62 years and overweight) were observed in both groups. Chitotriosidase activity ranged from 110 nmol/ml/hr to 1530 nmol/ml/hr in the CLI group and from 30 nmol/ml/hr to 440 nmol/ml/hr in the control group; demonstrating significantly elevated values in the CLI group ( p <0.001). Median plasma chitotriosidase activity was significantly elevated in smokers compared with non-smokers in both groups ( p <0.05). However, this activity had higher values in CLI than in control subjects. Receiver operating characteristic (ROC) analysis was then performed in order to verify the diagnostic accuracy of chitotriosidase as an inflammatory biomarker in CLI. Circulating chitotriosidase is a test which can potentially be used for the monitoring of CLI patients without other inflammatory conditions. However, the interpretation of elevated values must take into account the inflammatory response induced by tobacco exposure. © 2017 by the Association of Clinical Scientists, Inc.

Recombinant human growth hormone and nandrolone phenylpropionate are two different anabolic agents. This study was designed to investigate the effects of these anabolic agents on the healing of ischemic colon anastomosis in rats. Seventy adult male Wistar rats were divided into five groups (n = 14). Group I was the sham laparotomy group. In the other groups, surgical procedures consisting of transsection and anastomosis were made at a distance 3 cm from the peritoneal reflection. Group II was the nonischemic control group. Ischemic colon model was produced in the remaining groups. Group III was the untreated control group. Groups IV and V received recombinant human growth hormone and nandrolone phenylpropionate, respectively. Bursting pressure and hydroxyproline levels were measured on the third and seventh postoperative days to evaluate anastomotic healing. Recombinant human growth hormone increased both collagen deposition and bursting pressure significantly at postoperative Days 3 and 7 compared with the sham and untreated control groups (P < 0.005). When compared with the untreated control, nandrolone phenylpropionate significantly increased collagen deposition at postoperative Days 3 and 7 (P < 0.005) and bursting pressure only at postoperative Day 3 (P < 0.005). Recombinant human growth hormone has more favorable therapeutic effects on the healing of ischemic colonic anastomoses than nandrolone phenylpropionate. Recombinant human growth hormone also improves healing of nonischemic colonic anastomosis.

The purpose of the present study was to determine to what extent it is possible to improve the effectiveness of operation of sensorimotor rhythm-based brain-computer interfaces (SMR-BCI) by supplementing user training with elements modifying the characteristics of visual feedback. Four experimental groups had training designed to reinforce BCI control by: visual feedback in the form of dummy faces expressing emotions (Group 1); flashing the principal elements of visual feedback (Group 2) and giving both visual feedbacks in one condition (Group 3). The fourth group participated in training with no modifications (Group 4). Training consisted of a series of trials where the subjects directed a ball into a basket located to the right or left side of the screen. In Group 1 a schematic image a face, placed on the controlled object, showed various emotions, depending on the accuracy of control. In Group 2, the cue and targets were flashed with different frequency (4 Hz) than the remaining elements visible on the monitor. Both modifications were also used simultaneously in Group 3. SMR activity during the task was recorded before and after the training. In Group 3 there was a significant improvement in SMR control, compared to subjects in Group 2 and 4 (control). Differences between subjects in Groups 1, 2 and 4 (control) were insignificant. This means that relatively small changes in the training procedure may significantly impact the effectiveness of BCI control. Analysis of behavioural data acquired from all participants at training showed greater effectiveness in directing the object towards the right side of the screen. Subjects with the greatest improvement in SMR control showed a significantly lower difference in the accuracy of rightward and leftward movement than others.

The objective of the study was to examine the effectiveness of empowering in-service training programs for foreign nurse aides working in community-based long-term care (LTC) facilities. The design was a pretest and post-test design with experiment and control groups. The sample consisted of purposeful sampling from 10 LTC facilities in the Shihlin and Peitou areas of Taipei. A total of 35 foreign nurse aides participated in this study; 16 in the experimental group and 19 in the control group. The experimental group attended the training program for a 3-month period, whereas the control group did not receive any training. The research findings reveal that the training program was effective in increasing the work stress of workload/scheduling (Z = 2.01, p

Cellularity, viability and immunophenotype of mononuclear cells derived from the tibial marrow of C57bL/6 mice were measured after the 30-day "Bion-M1" space flight and subsequent 7-day recovery. Cell number in the flight group was significantly less than in the group of vivarium control. There was no difference in the parameter between the flight and control groups after the recovery. Viability of mononuclear cells was more than 95% in all examined groups. Flow cytometric analysis failed to show differences in bone marrow cell immunophenotype (CD45, CD34, CD90.1 (Thy1); however, the flight animals had more large-sized CD45+ mononuclears than the control groups of mice. These results indicate that spaceflight factors did not have significant damaging effects on the number or immunophenotype of murine bone marrow mononuclears. These observations are consistent with the previously made assumption of a moderate and reversible stress reaction of mammals to space flight.

The aim of this study was to investigate whether isometric neck extension exercise restores physiological cervical lordosis and reduces pain. Sixty-five patients with loss of cervical lordosis were randomly assigned to exercise (27 women, 7 men; mean age, 32.82 ± 8.83 yrs) and control (26 women, 5 men; mean age, 33.48 ± 9.67 yrs) groups. Both groups received nonsteroidal anti-inflammatory drugs for 10 days. The exercise group received additional therapy as a home exercise program, which consisted of isometric neck extension for 3 mos. Neck pain severity and cervical lordosis were measured at baseline and at 3 mos after baseline. Compared with baseline levels, cervical lordosis angle was significantly improved in the exercise group (P < 0.001) but not in the control group (P = 0.371) at the end of 3 mos. Moreover, the exercise group was significantly superior to the control group considering the number of patients in whom cervical lordosis angle returned to physiological conditions (85.2% vs. 22.5%; P < 0.001). At the end of 3 mos, pain intensity was significantly reduced in both groups compared with baseline levels (for all, P < 0.001). Nevertheless, considering the change from baseline to month 3, the reduction in pain was about twice in the exercise group compared with the control group (P < 0.001). Isometric neck extension exercise improves cervical lordosis and pain.

Honey is one of the oldest known medicines. Its medical and therapeutic importance has been recently rediscovered. Honey is an effective treatment for infected wounds and ulcers. The aim of this study was to determine the effect of honey as a topical therapy for intraoral wound healing in rats. Thirty-two male rats were divided into experimental and control groups (consisting of 16 rats, 4 animals in each group). A 2-mm mucosal defect was made to the depth of the periosteum using punch biopsy. Honey was applied to the wound every day, and the ulcer size was measured daily. On days 2, 4, 6, and 8, four rats were euthanized from each group (experimental and control groups), and tissues were histopathologically evaluated. Healing processes were studied as follows: the size of ulcer, inflammatory response, reepithelialization, and granulation tissue formation. The mean rank of wound size was significantly reduced in the honey group (2.50), as compared to the control group (6.50). Reepithelialization and granulation tissue formation mean rank were significantly higher in the honey group (6.50) than in the control group (2.50). Inflammation mean rank was statistically lower in the honey group (2.63) compared with the control group (6.38). Honey was shown to have a beneficial effect on the healing of oral ulcers in rats in this model. Further research may shed light on the effects of honey on different types of ulcers in humans.
