    This study's objective was to assess maintenance of treatment effects 3 months after completion of a 12-week Pivotal Response Treatment (PRT) parent education group. Families who completed the active treatment (N = 23) were followed for an additional 12 weeks to measure changes in language and cognitive skills. Results indicated a significant improvement in frequency of functional utterances, with maintenance at 3-month follow-up [F(2, 21): 5.9, p = .009]. Children also made significant gains on the Vineland Communication Domain Standard Score [F(2, 12):11.74, p = .001] and the Mullen Scales of Early Learning Composite score [F(1, 20) = 5.43, p = .03]. These results suggest that a brief PRT parent group intervention can lead to improvements in language and cognitive functioning that are maintained 12 weeks post treatment.

    2016-01-01

    Aims Three-monthly injections of paliperidone palmitate (PP-3M) represent a new and recently introduced long-acting antipsychotic therapeutic option. This review focuses on available data relating to the efficacy and safety of PP-3M and its position in the current therapeutic scenario. Method An analysis of PubMed, Scopus, and ISI Web of Knowledge databases was conducted, and all available papers on PP-3M, including poster presentations, were selected and considered for the purpose of the present review. Findings: to date, three full papers have been published, the first, a Phase 1 randomized, open label study investigating the pharmacokinetics, safety, and tolerability of the drug; the second, a Phase 3 double blind study vs placebo focusing on efficacy and tolerability; and the last relating to the practical use of PP-3M. The five posters identified describe data reported in the above-cited papers. Overall, the pharmacokinetic findings obtained in these studies highlight the feasibility of administering PP-3M on a 3-monthly basis, subsequent to the administration of four 1-monthly injections of PP at doses 3.5 times higher than the stabilized dose of 1-monthly injections of PP (ie, 175, 300, 450, and 525 mgs). The published studies highlight a significantly longer time to relapse compared to placebo, and significantly better results compared to placebo for all secondary end-points (Positive and Negative Syndrome Scale, Clinical Global Impression-Severity Scale, Personal and Social Performance Scale scores), in addition to reasonably good safety and tolerability profiles. Conclusion PP-3M emerges as a potential candidate for use as a first-line long-acting agent in the maintenance treatment of patients with schizophrenia. Further studies should however be conducted to confirm this expectation. In view of its efficacy, tolerability, and safety, together with the longer timespan between injections, PP-3M currently represents one of the best available options, and

    2014-01-01

    Background: To compare changes in the amount and distribution of dental plaque associated with placement of elastomeric modules over a self-ligating bracket during orthodontic treatment and to relate these changes to the periodontal inflammation. Materials and Methods: A cross-arch randomization trial was carried out at Bristol Dental School, United Kingdom. Clinical measurements of periodontal inflammation and plaque accumulation and microbiological test were done on 24 patients aged 11-14 years [Mean (SD) age = 12.6 (1.01) years] wearing fixed appliances (Damon 2 brackets, Ormco, Orange, CA, USA) at the start and 3 months into fixed orthodontic treatment. Results: In the first 3 months of treatment there was no statistically significant difference in bleeding on probing between incisors with and without elastomeric modules (P = 0.125 and 0.508, respectively). The difference in plaque accumulation was not statistically significant (P = 0.78). The difference in probing depths between the incisors was not statistically significant (P = 0.84). The microbiological analysis showed no difference. Conclusions: Based on this preliminary 3 months study, elastomeric modules were not significantly associated with any increased risk during treatment when compared to self-ligating brackets. The longer term studies are needed to further confirm the findings of the present study. PMID:24987657

    BACKGROUND Fractional non-ablative lasers keep the epidermis intact, while fractional ablative lasers remove it, making them theoretically more effective. OBJECTIVES To evaluate the clinical and histological alterations induced by fractional photothermolysis for treating photoaging, comparing the possible equivalence of multiple sessions of 1540nm Erbium, to one session of 2940nm Erbium. METHODS Eighteen patients (mean age 55.9) completed the treatment with three sessions of 1540nm fractional Erbium laser on one side of the face (50 mJ/mB, 15ms, 2 passes), and one session of 2940nm on the other side (5mJ/mB, 0.25ms, 2 passes). Biopsies were performed before and 3 months after treatment. Clinical, histological and morphometric evaluations were carried out. RESULTS All patients presented clinical improvement with no statistically significant difference (p> 0.05) between the treated sides. Histopathology revealed a new organization of collagen and elastic fibers, accompanied by edema, which was more evident with the 2940nm laser. This finding was confirmed by morphometry, which showed a decrease in collagen density for both treatments, with a statistical significance for the 2940nm laser (p > 0.001). CONCLUSIONS Three 1540nm sessions were clinically equivalent to one 2940nm session. The edema probably contributed to the positive results after three months, togheter with the new collagen and elastic fibers organization. The greater edema after the 2940nm session indicates that dermal remodeling takes longer than with 1540nm. It is possible that this histological superiority relates to a more prolonged effect, but a cohort longer than three months is needed to confirm that supposition. PMID:24770501

    The mechanism by which nonalcoholic fatty liver disease (NAFLD) progresses into nonalcoholic steatohepatitis (NASH) is unknown, however, the major process is oxidative stress with increased production of reactive oxygen species and excessive inflammatory cytokine generation. To date, there are no effective treatments for NASH and the published data with treatment using antioxidants are not satisfactory. Melatonin (MT), the potent endogenous antioxidant secreted in circadian rhythm by pinealocytes and in large amounts in the digestive system, was reported to improve oxidative status and to exert beneficial effects in NASH pathology in experimental animals, but no study attempted to determine the possible effectiveness of MT in humans with NASH. In this study, 42 patients (12 placebo controls and 30 MT-treated) with histological evidence (liver biopsy) of NASH and no history of alcohol abuse, were included. The treatment group took melatonin (2x5 mg/daily orally), while controls were treated with placebo. At baseline no significant differences between the groups were found for age, body mass index (BMI) as well as for plasma alanine aminotransferase (ALT), aspartate aminotransferase (AST), gamma-glutamyl transpeptidase (GGT), alkaline phosphatase (ALP), and concentrations of cholesterol, triglycerides (TG), glucose and MT. During the study period plasma ALT level and cholesterol concentration decreased significantly in both MT-treated and control groups, however AST and GGT levels decreased significantly only in MT-treated groups. Median value of AST level at baseline was 76.5 (64.2-114.2) IU/L and its percentage decrease at 4, 8 and 12 week was 20, 36 and 38%, resp. Baseline GGT median level was 113 (75.7-210.7) IU/L and its mean percentage decrease at week 4, 8 and 12 was 46, 48 and 47%, resp. Plasma ALP levels did not change significantly during MT treatment. Median value of plasma concentrations of MT (pg/mL) in MT-treated group rose from 7.5 (5.0-14.25) at

    A novel lotion formulation of fluticasone propionate 0.05% has recently become available. Two large, randomized, placebo-controlled, double-blind studies involving 438 subjects demonstrated its efficacy and safety when applied once daily in the treatment of atopic dermatitis in subjects from 3 months to 87 years of age. The studies were limited to 4 weeks duration of use of fluticasone lotion and did not assess longer term efficacy or side effects.

    Research findings are particularly important for medication choice for first-episode patients as individual prior medication response to guide treatment decisions is unavailable. We describe the first large-scale double-masked randomized comparison with first-episode patients of aripiprazole and risperidone, 2 commonly used first-episode treatment agents. One hundred ninety-eight participants aged 15-40 years with schizophrenia, schizophreniform disorder, schizoaffective disorder or psychotic disorder Not Otherwise Specified, and who had been treated in their lifetime with antipsychotics for 2 weeks or less were randomly assigned to double-masked aripiprazole (5-30 mg/d) or risperidone (1-6 mg/d) and followed for 12 weeks. Positive symptom response rates did not differ (62.8% vs 56.8%) nor did time to response. Aripiprazole-treated participants had better negative symptom outcomes but experienced more akathisia. Body mass index change did not differ between treatments but advantages were found for aripiprazole treatment for total and low-density lipoprotein cholesterol, fasting glucose, and prolactin levels. Post hoc analyses suggested advantages for aripiprazole on depressed mood. Overall, if the potential for akathisia is a concern, low-dose risperidone as used in this trial maybe a preferred choice over aripiprazole. Otherwise, aripiprazole would be the preferred choice over risperidone in most situations based upon metabolic outcome advantages and some symptom advantages within the context of similar positive symptom response between medications.

    This randomized controlled trial was designed to evaluate the effectiveness of using crisis coping cards (n = 32) in the case management of suicide prevention compared with case management without the use of coping cards (n = 32) over a 3-month intervention period. The generalized estimating equation was used to examine the interaction effect between treatments and time on suicide risk, depression, anxiety, and hopelessness. Results indicated that subsequent suicidal behaviors, severity of suicide risk, depression, anxiety, and hopelessness were reduced more in the coping card intervention group compared to the case management only group. Moreover, for the survival curves of time to suicide reattempt, the coping card group showed a significantly longer time to reattempt than the case management only group at 2-month and 3-month intervention periods.

    Bronchial asthma is a common disease in both the pediatric and adult populations, characterized by wide variations over short periods of time in resistance to airflow in intrapulmonary airways. A primary goal in the use of low- level laser therapy (LLLT) was the safe, effective and rapid palliation of symptoms owing to tracheal or bronchial obstruction. We have investigated the effects of LLLT comparatively with other modality trials in children's asthma. In the study were included 98 patients aged 10-18 years diagnosed with moderate or severe asthma, in attack- free period. The patients were divided into 3 groups. Group 1 received only laser therapy using extra meridian acupuncture points and scanning technique. Group 2 was treated only with inhaled Serevent 2 X 25 micrometers , two times daily, 3 months. Group 3 was tread with Theophylline retard in dosage of 15-mg/kg/12 h, 3 months. At the end of treatment we remarked a noticeable improvement of the clinical, functional and immunological characteristics at 83 percent of patients in group 1, comparatively with only 70 percent (group 2) and 53 percent (group 3). The LLLT had a very good action on bronchial patency , displayed an immunocorrecting action and is recommended in attack-free periods at children.

    Danshensu (3-(3,4-dihydroxyphenyl) lactic acid), a natural phenolic acid, is isolated from root of Salvia miltiorrhiza, and is widely used as a traditional Chinese medicine for treatment of various cardiovascular diseases. In the present study, toxicity of danshensu was evaluated in male and female dogs after 3-month continuous intravenous infusion. Beagle dogs were treated with danshensu at doses of 17, 50, and 150 mg/kg/day, and observed for 90 days followed by recovery periods. Measurements included clinical observations, body weight, food consumption, temperature, electro-cardiography (EGC), hematology, blood chemistry, urinalysis, gross necropsy, organ weight, and histopathology. No significant adverse effects on these parameters were observed. The only treatment-related finding was a hard knot at injection site observed in the 150 mg/kg group after 2-3 weeks continuous administration, and returned to normal after 3-4 days withdrawal. From these results, it might be concluded that danshensu did not produce any significant cumulative toxicity at the doses administered, as reflected by the various parameters investigated.

    2015-12-01

    OBJECT The health care landscape is rapidly shifting to incentivize quality of care rather than quantity of care. Quality and outcomes registry platforms lie at the center of all emerging evidence-driven reform models and will be used to inform decision makers in health care delivery. Obtaining real-world registry outcomes data from patients 12 months after spine surgery remains a challenge. The authors set out to determine whether 3-month patient-reported outcomes accurately predict 12-month outcomes and, hence, whether 3-month measurement systems suffice to identify effective versus noneffective spine care. METHODS All patients undergoing lumbar spine surgery for degenerative disease at a single medical institution over a 2-year period were enrolled in a prospective longitudinal registry. Patient-reported outcome instruments (numeric rating scale [NRS], Oswestry Disability Index [ODI], 12-Item Short Form Health Survey [SF-12], EQ-5D, and the Zung Self-Rating Depression Scale) were recorded prospectively at baseline and at 3 months and 12 months after surgery. Linear regression was performed to determine the independent association of 3- and 12-month outcome. Receiver operating characteristic (ROC) curve analysis was performed to determine whether improvement in general health state (EQ-5D) and disability (ODI) at 3 months accurately predicted improvement and achievement of minimum clinical important difference (MCID) at 12 months. RESULTS A total of 593 patients undergoing elective lumbar surgery were included in the study. There was a significant correlation between 3-month and 12-month EQ-5D (r = 0.71; p < 0.0001) and ODI (r = 0.70; p < 0.0001); however, the authors observed a sizable discrepancy in achievement of a clinically significant improvement (MCID) threshold at 3 versus 12 months on an individual patient level. For postoperative disability (ODI), 11.5% of patients who achieved an MCID threshold at 3 months dropped below this threshold at 12 months; 10

    2015-06-01

    The perinatal period is a time of high risk for women with unipolar and bipolar mood disorders. We discuss treatment considerations for perinatal mood disorders, including unipolar and bipolar depression as well as postpartum psychosis. We further explore the unique issues faced by women and their families across the full trajectory of the perinatal period from preconception planning through pregnancy and following childbirth. Treatment of perinatal mood disorders requires a collaborative care approach between obstetrics practitioners and mental health providers, to ensure that a thoughtful risk : benefit analysis is conducted. It is vital to consider the risks of the underlying illness versus risks of medication exposure during pregnancy or lactation. When considering medication treatment, attention must be paid to prior medication trials that were most efficacious and best tolerated. Lastly, it is important to assess the impact of individual psychosocial stressors and lifestyle factors on treatment response.

    1995-11-01

    Chlorine dioxide was injected into the water intakes at two power plants in Illinois and one in Indiana in an effort to eradicate the existing population of zebra mussels and mitigate further settlement in station river water cooling systems. Results of the treatments at Illinois Power Company`s Wood River Station on the Mississippi River, Central Illinois Public Service`s Meredosia Station on the Illinois River, and SI Energy`s Gallagher Station on the Ohio River are reported. Treatments were performed on a turnkey basis, with three treatments performed at Meredosia Station in 1994, six treatments performed at Wood River Station between July 1993 and September 1994, and 2 treatments performed at Gallagher Station in 1994. For each treatment, a contractor installed and operated a portable chlorine dioxide generator, monitored water quality and oxidant levels, and provided and monitored bioboxes containing test mussels. Results of the treatments were very favorable, indicating a good potential for periodic treatments with chlorine dioxide to control zebra mussel infestations in the raw water systems of power plants and other industrial facilities. Some difficulties with the chlorine dioxide generation system and cold temperature effects reduced the treatment effectiveness, particularly the second treatment at Gallagher Station. Average induced mortalities ranged from 70 to 100% at Wood River, 87 to 92% at Meredosia, and 30 to 100% at Gallagher for native mussels. Dechlorination successfully kept total oxidant residual levels at or below 0.05 ppM during all treatments at all stations.

    2006-12-01

    Arsenic concentrations of tubewell water that exceed acceptable limits poses a serious health problem in Bangladesh. Many Bangladeshis are now suffering from arsenic-related diseases. The objectives of this paper are to examine the extent of delay in seeking medical treatment by victims of arsenic poisoning and to identify factors contributing to this delay. Questionnaire survey successfully administered to 663 victims living in two rural areas of Bangladesh provided the major data source for this study. Analysis of survey data reveal that median delay period was 12 months, but the delay period ranged from 1 month to 18 years. Because of this extremely large range, the mean delay period was about 22 months. The study identified time of identification of symptoms of arsenicosis as the most significant determinant of treatment delay followed by treatment sought from members of mobile medical teams, perceived threat, and level of education. Based on the study findings, it is recommended that the Bangladesh government and NGOs involved in arsenic mitigation and prevention efforts should educate individuals at risk for arsenic poisoning about the benefits of seeking early treatment. This study also recommends to continue to dispatch mobile medical teams to the arsenic-impacted areas.

    Confined space, limited exercise equipment, rotating shift work and reduced sleep may affect cardiometabolic health in submariners. To test this hypothesis, 53 male U.S. Submariners (20–39 years) were studied before and after a 3-month routine submarine patrol. Measures included anthropometrics, dietary and physical activity, biomarkers of cardiometabolic health, energy and appetite regulation, and inflammation. Before deployment, 62% of submariners had a body fat % (BF%) ≥ 25% (obesity), and of this group, 30% met the criteria for metabolic syndrome. In obese volunteers, insulin, the homeostatic model assessment of insulin resistance (HOMA-IR), leptin, the leptin/adiponectin ratio, and pro-inflammatory chemokines growth-related oncogene and macrophage-derived chemokine were significantly higher compared to non-obese submariners. Following the patrol, a significant mean reduction in body mass (5%) and fat-mass (11%) occurred in the obese group as a result of reduced energy intake (~2000 kJ) during the patrol; and, independent of group, modest improvements in serum lipids and a mean reduction in interferon γ-induced protein 10 and monocyte chemotactic protein 1 were observed. Since 43% of the submariners remained obese, and 18% continued to meet the criteria for metabolic syndrome following the patrol, the magnitude of weight loss was insufficient to completely abolish metabolic dysfunction. Submergence up to 3-months, however, does not appear to be the cause of obesity, which is similar to that of the general population. PMID:26867201

Following the patrol, a significant mean reduction in body mass (5%) and fat-mass (11%) occurred in the obese group as a result of reduced energy intake (~2000 kJ) during the patrol; and, independent of group, modest improvements in serum lipids and a mean reduction in interferon γ-induced protein 10 and monocyte chemotactic protein 1 were observed. Since 43% of the submariners remained obese, and 18% continued to meet the criteria for metabolic syndrome following the patrol, the magnitude of weight loss was insufficient to completely abolish metabolic dysfunction. Submergence up to 3-months, however, does not appear to be the cause of obesity, which is similar to that of the general population. PMID:26867201

    Using data from two postpartum depression randomized trials, we examined the association between postpartum depressive symptoms and parenting practices among a diverse group of mothers. We examined the association between safety practices (back sleep position, car seat use, smoke alarm), feeding practices (breastfeeding, infant intake of cereal, juice, water), and health care practices (routine well child and Emergency Room (ER) visits) with 3-month postpartum depressive symptoms assessed using the Edinburgh Depression Scale (EPDS ≥10). Fifty-one percent of mothers were black or Latina, 33 % had Medicaid, and 30 % were foreign born. Depressed mothers were less likely to have their infant use back sleep position (60 vs. 79 %, p < .001), always use a car seat (67 vs. 84 %, p < .001), more likely to feed their infants water, juice, or cereal (36 vs. 25 %, p = .04 respectively), and to bring their babies for ER visits (26 vs. 16 %, p = .03) as compared with non-depressed mothers. In multivariable model, depressed mothers remained less likely to have their infant use the back sleep position, to use a car seat, and to have a working smoke alarm in the home. Findings suggest the need to intervene early among mothers with depressive symptoms and reinforce positive parenting practices. PMID:25374288

    Septic arthritis in infants is rare and can be difficult to diagnose. This study reviewed a series of patients younger than 3 months to identify factors that may assist in early diagnosis and treatment. A query of records at a large Midwestern pediatric hospital (1994-2010) was performed to identify all patients younger than 3 months at the time of diagnosis. Analysis included birth history, joint involvement, physical examination findings, laboratory results, imaging results, method of treatment, and outcome. In 14 cases (11 boys, 3 girls; mean age at diagnosis, 42.2 days), complete records were available for review. Involved joints included the knee, hip, and shoulder. The most common findings on physical examination were decreased range of motion (100%), tenderness (100%), and swelling (71.4%). Mean temperature was 38.5°C. Mean white blood cell count was 18.5 K/µL, mean erythrocyte sedimentation rate was 48.9 mm/h, and mean C-reactive protein level was 6.1 mg/dL. More than half (57.1%) of joint aspirates grew positive cultures, and 41.7% of blood cultures had positive results. Causative organisms were group B streptococcus, methicillin-sensitive Staphylococcus aureus, Haemophilus influenzae, Streptococcus pneumoniae, Salmonella enterica, and Candida albicans. The most common physical examination findings in infants younger than 3 months with septic arthritis include tenderness, decreased range of motion, and swelling. White blood cell count, C-reactive protein level, and erythrocyte sedimentation rate are likely to be elevated, but these findings should be used in combination with findings on physical examination and radiographic studies to aid in diagnosis.

    Abstract Background: Urethral polyps are rare benign pathologies seen in the male posterior urethra, more frequently originating from verumontanum. In this article, we aimed to discuss diagnosis and treatment of a urethral polyp causing hematuria and urinary infection in a 3-month-old male infant. This is the first case in the literature in which a urethral polyp is treated with Holmium yttrium-aluminum-garnet (YAG) laser. Case Presentation: The patient was a 3-month-old male infant, and complains were hematuria and crying during micturition. Ultrasonography and voiding cystourethrogram were used for diagnosis. Urethral polyp was observed on urethrocystoscopy. Ablation was performed with a newborn cystoscope. Conclusion: Urethral polyp can cause hematuria and urinary obstruction and should be considered in the differential diagnosis of pathologies such as posterior urethral valve and cecoureterocele that could cause infravesical obstruction. Holmium-YAG laser is a good choice of treatment with easy application possibilities using a newborn cystoscope, especially for newborns and infants who have thin urethra. PMID:27579428

    Background: Clinicians are constantly faced with the challenge of designing training programs for injured and noninjured athletes that maximize healing and optimize performance. Periodization is a concept of systematic progression—that is, resistance training programs that follow predictable patterns of change in training variables. The strength training literature is abundant with studies comparing periodization schemes on uninjured, trained, and untrained athletes. The rehabilitation literature, however, is scarce with information about how to optimally design resistance training programs based on periodization principles for injured athletes. The purpose of this review is to discuss relevant training variables and methods of periodization, as well as periodization program outcomes. A secondary purpose is to provide an anecdotal framework regarding implementation of periodization principles into rehabilitation programs. Evidence Acquisition: A Medline search from 1979 to 2009 was implemented with the keywords periodization, strength training, rehabilitation, endurance, power, hypertrophy, and resistance training with the Boolean term AND in all possible combinations in the English language. Each author also undertook independent hand searching of article references used in this review. Results: Based on the studies researched, periodized strength training regimens demonstrate improved outcomes as compared to nonperiodized programs. Conclusions: Despite the evidence in the strength training literature supporting periodization programs, there is a considerable lack of data in the rehabilitation literature about program design and successful implementation of periodization into rehabilitation programs.

    The only known genetic causes of hereditary diffuse gastric cancer (HDGC) are germline mutations in the CDH1 gene.- CDH1 mutation carriers have a lifetime risk of 70-80% of developing diffuse gastric cancer. As periodic gastric surveillance is of limited value in detecting early stages of HDGC, prophylactic gastrectomy is advised for this patient group. This group is small and little is known about other types of familial gastric cancer. The Dutch Working Group on Hereditary Gastric Cancer has formulated criteria for various aspects of medical care for families and individuals at high risk of developing gastric cancer, including criteria for diagnostics and periodic gastric surveillance. In order to optimize the care and increase the knowledge on hereditary gastric cancer it is important to centralize medical care for these patients.

    Aerobic exercise (AE) has been shown to improve cognition in patients with schizophrenia. However, it remains unclear whether these exercise-induced cognitive benefits persist beyond the training period. Accordingly, the present study sought to examine the immediate and maintenance effects of AE on a wide range of cognitive functions in 75 schizophrenia patients randomized to 12 weeks of either moderate-intensity treadmill exercise or stretching and toning exercise that served as a control. Participants completed assessments of neurocognition and cardiovascular fitness at pretest, posttest, and 3-month follow-up. The results showed that the AE group outperformed the controls on processing speed and attention at the end of intervention. The two groups did not differ significantly in any cognitive outcome measured at follow-up; however, improvement over time was noted in certain cognitive domains in AE group. The average effect sizes at follow-up were 0.53 and 0.35 for AE and control groups, respectively. There were no significant between-group differences in aerobic fitness at posttest and follow-up, and that fitness level was not related to changes in cognitive performance. These findings provide preliminary evidence for a trend towards beneficial effects of physical activity on cognition over a short follow-up period in favor of AE. PMID:27525830

  2. Chronic Alcohol Treatment in Rats Alters Sleep by Fragmenting Periods of Vigilance Cycling in the Light Period with Extended Wakenings

    Studies have shown that disturbed sleep produced by chronic alcohol abuse in humans can predict relapse drinking after periods of abstinence. How alcohol produces disturbed sleep remains unknown. In this study we used a novel analysis of sleep to examine the effects of alcohol on sleep patterns in rats. This analysis separates waking into multiple components and defines a period labeled vigilance cycling (VC) in which the rat rapidly cycles through various vigilance states. These VC episodes are separated by long duration wake periods (LDW). We find that 6 weeks of alcohol (6% in a liquid diet) caused fragmentation of extended VC episodes that normally occur in the light period. However, total daily amounts of slow-wave sleep (SWS) and rapid-eye movement sleep (REMS) remained constant. The daily amount of wake, SWS, and REMS remained constant because the alcohol treated rats increased the amount of VC in the dark period, and the sleep nature of VC in the dark period became more intense. In addition, we observed more wake and less REMS early in the light period in alcohol treated rats. All effects completely reversed by day 16 of alcohol withdrawal. Comparison of the effects of chronic alcohol to acute alcohol exposure demonstrated the effects of chronic alcohol are due to adaptation and not the acute presence of alcohol. The effects of chronic alcohol treatment in rats mimic the effects reported in humans (REMS suppression, difficulty falling asleep, and difficulty remaining asleep). PMID:19014977

    This paper summarizes the EPRI report (TR-105202) on the same topic as well as presents changes in current thinking on the suitability (applicability) of chlorine dioxide for fouling control. Chlorine dioxide was tested as a zebra mussel biocide at two steam electric generating stations in Illinois and one in Indiana. The purpose of these studies was to determine the efficacy of chlorine dioxide in killing zebra mussels and to develop site specific treatment programs for the three utilities. The Electric Power Research Institute (EPRI) Zebra Mussel Consortium sponsored the testing of this recent use of chlorine dioxide. The raw water system at Central Illinois Public Service`s Meredosia Station, on the Illinois River, received applications of chlorine dioxide in April, July, and September 1994. The raw water system at Illinois Power Company`s Wood River Station, on the Mississippi River, received applications in July 1993, January, April, May, July, and September 1994. The Gallagher Station, on the Ohio River, was treated in July and October 1994. Chlorine dioxide was generated on-site and injected into the water intake structure. Both cooling and service water systems were treated at the facilities. 6 refs., 13 figs.

    MCID at 3 and 12 months. The discordance rates of achieving or not achieving MCID for ODI were in the range of 19% to 27% for all diagnoses and treatments (decompression with and without fusion). The positive and negative predictive value of 3-months ODI to predict 12-month ODI was 86% and 60% for MCID and 82% and 67% for SCB. CONCLUSIONS Based on their findings, the authors conclude the following: 1) Predictive methods for functional outcome based on early patient experience (i.e., baseline and/or 3-month data) should be used to help evaluate the effectiveness of procedures in patient populations, rather than serving as a proxy for long-term individual patient experience. 2) Prospective longitudinal registries need to span at least 12 months to determine the effectiveness of spine care at the individual patient and practitioner level.

    This study explores the emergence of triadic interactions through the example of book sharing. As part of a naturalistic study, 10 infants were visited in their homes from 3–12 months. We report that (1) book sharing as a form of infant-caregiver-object interaction occurred from as early as 3 months. Using qualitative video analysis at a micro-level adapting methodologies from conversation and interaction analysis, we demonstrate that caregivers and infants practiced book sharing in a highly co-ordinated way, with caregivers carving out interaction units and shaping actions into action arcs and infants actively participating and co-ordinating their attention between mother and object from the beginning. We also (2) sketch a developmental trajectory of book sharing over the first year and show that the quality and dynamics of book sharing interactions underwent considerable change as the ecological situation was transformed in parallel with the infants' development of attention and motor skills. Social book sharing interactions reached an early peak at 6 months with the infants becoming more active in the coordination of attention between caregiver and book. From 7 to 9 months, the infants shifted their interest largely to solitary object exploration, in parallel with newly emerging postural and object manipulation skills, disrupting the social coordination and the cultural frame of book sharing. In the period from 9 to 12 months, social book interactions resurfaced, as infants began to effectively integrate manual object actions within the socially shared activity. In conclusion, to fully understand the development and qualities of triadic cultural activities such as book sharing, we need to look especially at the hitherto overlooked early period from 4 to 6 months, and investigate how shared spaces of meaning and action are structured together in and through interaction, creating the substrate for continuing cooperation and cultural learning.

    The main purpose of the study was to examine if 3 months of bicycle endurance training alters the red cell deformability in non insulin dependent type 2 diabetes mellitus men.The red cell deformability was measured with the Laser assisted optical rotational cell analyzer. The maximal elongation index and the semimaximal shear stress were measured with the Lineweaver Burke model.At the beginning and the end of the intervention the patients passed a bicycle ergometry test. As a reference group, 13 males without diabetes passed the same testing procedure. Blood samplings were taken before testing, immediately after physical exhaustion and after a 30 min recovery phase.After the training period diabetic patients could significantly reduce BMI, fasting glucose and HbA1c. The reference group had significantly higher elongation indices than the diabetes patients independent from training status. After the training period the basal values of the maximal elongation index did not change significantly. However, maximal elongation indices were significantly reduced after physical examination and in resting time.The semimaximal shear stress of diabetes patients did not alter during the training period. In comparison to the reference group semimaximal shear stress was significantly reduced at all measurement times.This pilot study proves that the maximal elongation index is significantly decreased in diabetes mellitus patients. After 3 months endurance training the red cells become more rigid while the semimaximal shear stress remains constant. Further interventions are required to analyze the exact cause of the presented findings.

    The study comprises an analysis of the effect of treatment with a modified activator combined with a high-pull headgear during a standardized observation period of the initial 6 months of treatment. All patients (24 girls and 32 boys, aged 8.5 to 15 years) had severe skeletal Class II malocclusion. In the first part of the study, the effect of treatment with the appliance both day and night is compared with the effect when it was worn only at night. Only a small and nonsignificant difference was found, but the patients tended to cooperate better if they were instructed to wear the appliance continuously. In the second part of the study, the effect of treatment is related to the somatic maturation of the patients. Longitudinal records of standing height were used to assess whether treatment had been performed before maximal pubertal growth (prepeak period), during maximal pubertal growth (peak period), or after maximal pubertal growth (postpeak period). The skeletal effect was significantly greater in boys treated during the peak period than in those treated during the prepeak period and a similar tendency, although not significant, was found among girls. The number of patients treated during the postpeak period was too small for statistical analysis.

    To determine the potential toxicity of prolonged aerosol tobramycin administration, 22 patients with cystic fibrosis were monitored while receiving inhaled tobramycin three times a day for 12 weeks. Prior to, four times during administration and approximately 6 weeks after discontinuation of treatment, we assessed pulmonary function, weight, height, body temperature, eighth cranial nerve function, serum creatinine, blood urea nitrogen, urinary creatinine clearance, plasma iothalamate clearance, urinary beta-2 microglobulin concentration, and Pseudomonas aeruginosa density in sputum. There was no detectable laboratory evidence of nephrotoxicity. Neither a decrease in auditory acuity (range 250-20,000 Hz) nor vestibular dysfunction was detected. Pulmonary function tests significantly improved during the first month in all subjects (P less than 0.05) but returned to enrollment values by the end of the 12th week of administration of tobramycin aerosol. Sputum P. aeruginosa density initially decreased from a mean of 10(7) cfu/gm to a mean of 10(4) cfu/gm after 2 weeks of aerosol tobramycin administration and remained significantly below the enrollment value throughout. Coincident with the reduced bacterial density, a reduction in cough frequency and sputum production, as well as a weight gain was observed. Seventy-three percent of the patients with sputum P. aeruginosa isolates susceptible to tobramycin on enrollment yielded resistant organisms during aerosol administration. However, 1 year later all sputum P. aeruginosa isolates obtained from patients were susceptible to tobramycin. We conclude that thrice daily aerosol tobramycin administration for 3 months is not associated with detectable eighth cranial nerve or renal toxicity. Transient emergence of tobramycin resistant P. aeruginosa may occur.

    Microbial penetration inside the implants internal cavity produces a bacterial reservoir that is associated with an area of inflamed connective tissue facing the fixture-abutment junction. The aim of this clinical trial is to evaluate the effectiveness of a 1 percent chlorhexidine gel on the internal bacterial contamination of implants with screw-retained abutments and on the level of AST secreted in peri-implant crevicular fluid. Twenty-five patients (aged 29 to 58 years) each received one implant. Three months after the end of the restorative treatment, and immediately after a clinical and radiographic examination and the abutment removal, microbiological samples were obtained from the internal part of each fixture and biochemical samples were collected by peri-implant sulci. The patients were then divided into two groups: the control (CG; n=10) and test (TG; n=15) groups. The CG had the abutment screwed into place and the crown cemented without any further intervention. In contrast, before the abutment placement and screw tightening, the TG had the internal part of the fixture filled with a 1 percent chlorhexidine gel. Three months later, the same clinical, microbiological and biochemical procedures were repeated in both groups. Total bacterial count, specific pathogens and AST activity were detected. The clinical parameters remained stable throughout the study. From baseline to the 3-month examination, the total bacterial counts underwent a significant reduction only in the TG. In contrast, the AST activity showed a significant increase in the CG. The administration of a 1% chlorhexidine gel appears to be an effective method for the reduction of bacterial colonization of the implant cavity and for safeguarding the health status of peri-implant tissue over a 3-month administration period.

    This randomized controlled study (ClinicalTrials.gov NCT02007616) investigated the maintenance of training effects of 20 1-hr non-action video game training sessions with selected games from a commercial package on several age-declining cognitive functions and subjective wellbeing after a 3-month no-contact period. Two groups of cognitively normal older adults participated in both the post-training (posttest) and the present follow-up study, the experimental group who received training and the control group who attended several meetings with the research team during the study but did not receive training. Groups were similar at baseline on demographics, vocabulary, global cognition, and depression status. Significant improvements in the trained group, and no variation in the control group had been previously found at posttest, in processing speed, attention and visual recognition memory, as well as in two dimensions of subjective wellbeing. In the current study, improvement from baseline to 3 months follow-up was found only in wellbeing (Affection and Assertivity dimensions) in the trained group whereas there was no change in the control group. Previous significant improvements in processing speed, attention and spatial memory become non-significant after the 3-month interval. Training older adults with non-action video games enhanced aspects of cognition just after training but this effect disappeared after a 3-month no-contact follow-up period. Cognitive plasticity can be induced in older adults by training, but to maintain the benefits periodic boosting sessions would be necessary.

    The response to a time periodic treatment of the immunotherapy in a stochastic model of tumor-immune interaction is numerically investigated. Due to the effect of synchronization among the intrinsic oscillation and the treatment, an enhanced extinction of the tumor cells is observed. It suggests that compared with the static treatment, by controlling the period of the treatment, the time periodic treatment could be an effective way of treatment leading to tumor extinction.

    Several devices and medications have been used to address poststroke spasticity. Yet, spasticity's impact on outcomes remains controversial. Using data from a cohort of 460 ischemic stroke patients, we previously published a validated multivariable regression model for predicting 3-month modified Rankin Score (mRS) as an indicator of functional outcome. Here, we tested whether including spasticity improved model fit and estimated the effect spasticity had on the outcome. Spasticity was defined by a positive response to the question "Did you have spasticity following your stroke?" on direct interview at 3 months from stroke onset. Patients who had expired by 90 days (n = 30) or did not have spasticity data available (n = 102) were excluded. Spasticity affected the 3-month functional status (β = 0.420, 95 CI = 0.194 to 0.645) after accounting for age, diabetes, leukoaraiosis, and retrospective NIHSS. Using spasticity as a covariable, the model's R (2) changed from 0.599 to 0.622. In our model, the presence of spasticity in the cohort was associated with a worsened 3-month mRS by an average of 0.4 after adjusting for known covariables. This significant adverse effect on functional outcomes adds predictive value beyond previously established factors. PMID:25147752

    Recently, nonequilibrium atmospheric-pressure plasmas have been intensively studied for biological applications. However, the each effect of species in plasmas to biological tissue has not been clarified yet because various factors exist in the plasmas. Accordingly, we have studied effects of atomic oxygen dose on cell growth such as budding yeast and mouse NIH3T3 fibroblasts of mammalian cells. Both of cells were suspended with PBS, and treated using oxygen radical source. In order to prevent the radicals from reacting with the ambient air, the treatment region was surrounded by a plastic cover and purged with Ar. The proliferative effect of 15 % was observed at the O3Pj dose of around 1 . 0 ×1017 cm-3 in NIH3T3 cells as well as in yeast cells. Moreover, periodic oxygen treatment enhanced the effect in budding yeast cells. The best interval of periodic oxygen radical treatment was around 2 hours, which is almost the same period as that of their cell cycle. With the optimum interval time, we have investigated the effect of the number of the treatments. As the number of treatments increases, the growth rate of budding yeast cells was gradually enhanced and saturated at thrice treatments. This work was partly supported by JSPS KAKENHI Grant Numbers 26286072 and project for promoting Research Center in Meijo University.

    Blunt traumatic infrarenal aortic injuries are unusual, and the formation of a delayed pseudoaneurysm of the aorta is even more rare. In this report, a young woman developed a small intimal flap of the infrarenal aorta after a motor vehicle accident which progressed into a 3 cm pseudoaneurysm after 3 months. Operative repair was successful and the patient recovered. This case illustrates the importance of repeat imaging of small blunt aortic injuries since progression can occur. PMID:27252519

    Objectives Medical comorbidities affect outcome in elderly patients with hip fracture. This study was designed to preliminarily evaluate the usefulness of a hip-fracture unit led by an internal medicine specialist. Methods In-hospital and 3-month outcomes in patients with hip fracture were prospectively evaluated in 121 consecutive patients assessed before and followed after surgery by a multidisciplinary team led by internal medicine specialist; 337 consecutive patients were recalled from ICD-9 discharge records and considered for comparison regarding in-hospital mortality. Results In the intervention period, patients treated within 48 hours were 54% vs. 26% in the historical cohort (P<0.0001). In-hospital mortality remained stable at about 2.3 per 1000 person-days. At 3 months, 10.3% of discharged patients had died, though less than 8% of patients developed postoperative complications (mainly pneumonia and respiratory failure). The presence of more than 2 major comorbidities and the loss of 3 or more BADL were independent predictors of death. 50/105 patients recovered previous functional capacity, but no independent predictor of functional recovery could be identified. Mean length of hospital stay significantly decreased in comparison to the historical cohort (13.6± 4.7 vs 17 ± 5 days, p = 0.0001). Combined end-point of mortality and length of hospitalization < 12 days was significantly lower in study period (27 vs 34%, p <0.0132). Conclusions Identification and stabilization of concomitant clinical problems by internal medicine specialists may safely decrease time to surgery in frail subjects with hip fracture. Moreover, integrated perioperative clinical management may shorten hospital stay with no apparent increase in in-hospital mortality and ultimately improve the outcome. These results are to be confirmed by a larger study presently ongoing at our institution. PMID:27389193

    This report examines coparenting and triadic interactions in 19 unmarried, first-time African American families as fathers, mothers, and 3-month-old infants navigated the Lausanne Trilogue Play (LTP; E. Fivaz-Depeursinge & A. Corboz-Warnery, ). Parents in 10 of the 19 families reported coresidence at the time of the 3-month assessment, and the other 9 sets of coparents lived apart. All participating families had taken part in a prenatal intervention emphasizing the importance of father engagement in children's lives, and in all families, parents reported episodic to regular father contact with the children at 3 months. Analyses of LTP sessions revealed that 9 of the 19 families exhibited high levels of coparenting solidarity-cooperation and family warmth accompanied by low levels of coparenting competition and disengagement. Among the remaining 10 families, competitiveness (verbal sparring, interference) and/or disengagement (repeated, episodic absenting by one or both parents from the ongoing interaction) signaled strain and challenges to solidarity. Differences between the higher and lower solidarity groups were found in father-reported relationship rapport. However, coresidentiality versus noncoresidentiality of the parents did not distinguish high- from low-solidarity groups. A case analysis of one family's triadic session is presented to elucidate the rich potential for clinical intervention in triadic work with fragile family systems. Implications of the study and its findings for theory, research, and clinical work with unmarried fathers and families, along with limits of the study design and generalizability of findings, are discussed.

    Objective. The aim of this study was to evaluate the effect of gentle tactile stimulation on the fetus in its temperament 3 months after birth. Method. A total of 302 mother-3-month-infant dyads enrolled the retrospective cohort study. 76 mothers had regular gentle tactile stimulation on the fetus in their pregnancy; 62 mothers had irregular tactile stimulation on the fetus, and the rest of 164 mothers who had no tactile stimulation served as nonexposure group. Temperament was assessed using the EITS (a nine-dimensional scale of temperament). Results. Significant difference in temperament type was found among infants in 3 groups at 3 months of age. In the regular practice group, the babies with easy type temperament accounted for 73.7%, which was higher than that in irregular practice group (53.2%, P = 0.012) and that in the control group (42.1%, P < 0.001). Compared to infants in no practice group, the infants who had received regular gentle tactile stimulation before birth were lower in negative mood (P = 0.047) while higher in adaptability (P < 0.001), approach (P = 0.001), and persistence (P = 0.001), respectively. Conclusion. Regular gentle tactile stimulation on fetus may promote the formation of easy type infant temperament. PMID:26180374

    Previous meta-analyses reported mortality estimates of 12-month post-antiretroviral therapy (ART) initiation; however, 40%-60% of deaths occur in the first 3 months on ART, a more sensitive measure of averted deaths through early ART initiation. To determine whether early mortality is dropping as treatment thresholds have increased, we reviewed studies of 3 months on ART initiation in low- to middle-income countries. Studies of 3-month mortality from January 2003 to April 2016 were searched in 5 databases. Articles were included that reported 3-month mortality from a low- to middle-income country; nontrial setting and participants were ≥15. We assessed overall mortality and stratified by year using random effects models. Among 58 included studies, although not significant, pooled estimates show a decline in mortality when comparing studies whose enrollment of patients ended before 2010 (7.0%; 95% CI: 6.0 to 8.0) with the studies during or after 2010 (4.0%; 95% CI: 3.0 to 5.0). To continue to reduce early HIV-related mortality at the population level, intensified efforts to increase demand for ART through active testing and facilitated referral should be a priority. Continued financial investments by multinational partners and the implementation of creative interventions to mitigate multidimensional complex barriers of accessing care and treatment for HIV are needed.

    Purpose Retinoblastoma is the most common primary malignant intra-ocular tumor in children. Although intra-arterial chemotherapy (IAC) by selectively infusing chemotherapy through the ophthalmic artery has become an essential technique in the treatment of advanced intra-ocular retinoblastoma in children, the outcome of IAC as primary therapy for infants less than 3 months of age remains unknown. In this retrospective study, we reviewed the outcome of IAC as primary therapy for retinoblastoma in infants less than 3 months of age. Methods We retrospectively reviewed ten retinoblastoma patients attending our center from January 2009 to September 2015 and beginning primary IAC before the age of 3 months. The patient characteristics, overall outcomes and therapy-related complications were assessed. Results The mean patient age at the first IAC treatment was 10.4 weeks (range 4.9–12.9 weeks). These eyes were classified according to the International Classification of Retinoblastoma (ICRB) as group A (n = 0), B (n = 2), C (n = 0), D (n = 9), or E (n = 2). A total of 28 catheterizations were performed, and the procedure was stopped in one patient because of internal carotid artery spasm. Each eye received a mean of 2.6 cycles of IAC (range 2–4 cycles). After IAC with a mean follow-up of 28.3 months (range 9–65 months), tumor regression was observed in 12 of 13 eyes. One eye was enucleated due to tumor progression. All patients are alive and no patient has developed metastatic disease or other malignancies. Conclusions Our experience suggests IAC as primary therapy is a feasible and promising treatment for retinoblastoma in infants less than 3 months of age. PMID:27504917

  12. Lessons learned from muscle fatigue: implications for treatment of patients with hyperkalemic periodic paralysis.

    2012-12-01

    Hyperkalemic periodic paralysis (HyperKPP) is a disease characterized by periods of myotonic discharges and paralytic attacks causing weakness, the latter associated with increases in plasma [K(+)]. The myotonic discharge is due to increased Na(+) influx through defective Na(+) channels that triggers generation of several action potentials. The subsequent increase in extracellular K(+) concentration causes excessive membrane depolarization that inactivates Na(+) channels triggering the paralysis. None of the available treatments is fully effective. This paper reviews the capacity of Na(+) K(+)ATPase pumps, KATP and ClC-1 Cl(-) channels in improving membrane excitability during muscle activity and how using these three membrane components we can study future and more effective treatments for HyperKPP patients. The review of current patents related to HyperKPP reinforces the need of novel approaches for the treatment of this channelopathy.

    A method for easy and fast regeneration of aqueous periodate solutions from dialdehyde cellulose (DAC) production by ozone treatment is presented, along with a direct and reliable simultaneous quantification of iodate and periodate by reversed-phase HPLC. The influence of iodate and ozone concentration, solution pH, and reaction time on the regeneration efficiency was studied, as well as the reaction kinetics. Regeneration of spent periodate solutions by ozone was successfully performed in alkaline medium, which favors the formation of free (.) OH radicals, as supported by the addition of radical scavengers and quantum mechanical calculations. At pH 13 and an ozone concentration of approximately 150 mg L(-1) , periodate was completely regenerated from a 100 mm solution of iodate within 1 h at room temperature. A cyclic process of cellulose oxidation and subsequent regeneration of spent periodate with 90 % efficiency has been developed. So far, commercial applications of DAC have been hampered by difficulties in reusing the costly periodate. This work overcomes this hurdle and presents a highly efficient, clean, and low-cost protocol for the preparation of DAC with integrated periodate recycling, with the possibility of scaling the process up.

    Forty-five adolescent and preadolescent patients (42 females, three males) with anorexia nervosa (AN) were treated in a pediatric day care unit of a large urban hospital by a multidisciplinary team. In our treatment model, the pediatrician has the responsibility for the initial evaluation and physical rehabilitation while the pediatric psychiatrist does the initial evaluation of the patient and family and is available for intervention in an emergency. Parents are actively involved in the treatment program. Family psychotherapy is recommended for each patient and his or her family. Among 45 patients, 24 did not enter psychotherapy during the first 2 months of the refeeding period, while the remaining 21 patients started psychotherapy (family and/or individual) during this period. Weight gain was higher in the group without formal psychotherapy during the initial period of refeeding (7.3 +/- 3.1 kg versus 5 +/- 2.5 kg; p less than 0.01). It is suggested that the initiation of structured psychotherapy is not mandatory and does not contribute to treatment effectiveness in the acute phase when emaciation and negativism may hinder the psychotherapeutic process. We believe a multidisciplinary team, together with the parents, is the treatment of choice during the acute phase of AN.

    Objective Serum soluble corin has been associated with stroke. However, whether it is associated with stroke prognosis has not yet been studied. Therefore, we aimed to study the association of serum soluble corin with risk of poor outcomes within 3 months after stroke. Methods We followed 522 stroke patients for 3 months to identify major disability, death and vascular events. Serum soluble corin was measured at baseline for all participants. Logistic regression was used to examine the associations of baseline serum soluble corin with outcomes of stroke, adjusting for age, sex, baseline NIHSS score, hours from onset to hospitalization, smoking, drinking, hypertension, diabetes, coronary heart disease, atrial fibrillation, family history of stroke, and stroke subtype. Results Patients with high corin had a significantly lower crude risk for the composite outcome of major disability or death (OR = 0.64, 95%CI: 0.43–0.96) than patients with low corin (the lowest tertile). After adjustment for age and baseline NIHSS score, patients with high corin still had a significantly lower risk for the composite outcome of major disability or death (OR = 0.60, 95%CI: 0.36–0.99). This association became bottom line significant after additionally adjusting for other conventional factors (OR = 0.61, P = 0.058). No association was found between serum soluble corin and other composite outcomes. Conclusion Serum soluble corin deficiency predicted risk for major disability within 3 months after stroke, independent of baseline neurological deficient. Our results may indicate a probable role of corin in stroke prognosis. PMID:27658255

    Visceral solitary myofibromas are uncommon in childhood. We report a case of a solitary asymptomatic visceral myofibroma of the bladder trigone occurring in a 3-month-old boy. Once malignancies were ruled out by cystoscopy, radical excision was performed in order to avoid any potential impairment of bladder dynamic. Postoperative course was uneventful and patient was discharged on day 3 after surgery. After 36 months of follow-up, the patient is toilet-trained and remains well; bladder function is normal.

    This randomized controlled study (ClinicalTrials.gov NCT02007616) investigated the maintenance of training effects of 20 1-hr non-action video game training sessions with selected games from a commercial package on several age-declining cognitive functions and subjective wellbeing after a 3-month no-contact period. Two groups of cognitively normal older adults participated in both the post-training (posttest) and the present follow-up study, the experimental group who received training and the control group who attended several meetings with the research team during the study but did not receive training. Groups were similar at baseline on demographics, vocabulary, global cognition, and depression status. Significant improvements in the trained group, and no variation in the control group had been previously found at posttest, in processing speed, attention and visual recognition memory, as well as in two dimensions of subjective wellbeing. In the current study, improvement from baseline to 3 months follow-up was found only in wellbeing (Affection and Assertivity dimensions) in the trained group whereas there was no change in the control group. Previous significant improvements in processing speed, attention and spatial memory become non-significant after the 3-month interval. Training older adults with non-action video games enhanced aspects of cognition just after training but this effect disappeared after a 3-month no-contact follow-up period. Cognitive plasticity can be induced in older adults by training, but to maintain the benefits periodic boosting sessions would be necessary. PMID:25926790

    Sensitivity to orientation is critical for making a whole and complete picture of the world. We measured the orientation tuning of mechanisms in the visual cortex of typically developing 3-month-olds and adults using a nonlinear analysis of the two-input steady-state Visually Evoked Potential (VEP). Two gratings, one a fixed test and the other a variable orientation masker were tagged with distinct temporal frequencies and the corresponding evoked responses were measured at the harmonics of the test and masker frequencies and at a frequency equal to the sum of the two stimulus frequencies. The magnitude of the sum frequency component depended strongly on the relative orientation of the test and masker in both infants and adults. The VEP tuning bandwidths of the 3-month-olds measured at the sum frequency were similar to those of adults, suggesting that behavioral immaturities in functions such as orientation discrimination and contour integration may result from other immaturities in long-range lateral projections or feedback mechanisms.

    The prevalence of bipolar disorder (BD) in males and females is almost equal. The onset of BD in females typically occurs during the reproductive years, complicating its treatment. Although it was once believed that pregnancy prevents recurrence, studies have shown that recurrence is common and severe during pregnancy. On the other hand, the effects of pharmacological treatment on obstetrical outcome are not well known and some of these agents are considered teratogenic. Thus, the decision to treat pregnant patients with psychotropic agents requires solving an ethical dilemma. Risk-benefit decisions should be made while considering both the risk of relapse of BD and its morbidity, and the risk of fetal exposure to psychotropic medications. Moreover, the risk of recurrence increases dramatically in the postpartum period. It is well known that all of the psychotropic medications studied enter the breast milk. Thus, their effects on infants should be considered while prescribing for a breastfeeding mother. The aim of this review was to discuss the safety profiles of the treatment options for pregnant and breastfeeding BD patients. Firstly, each medication's effects on organ dysgenesis, neonatal toxicity, and neurobehavioral development, and their associated adverse events during pregnancy and the postpartum period are discussed, with a focus on the emerging literature. Given this background, practical suggestions on tailoring treatment in BD patients, from preconception to breastfeeding are highlighted.

    Objective: To evaluate the efficacy and safety of gaboxadol in the treatment of Primary Insomnia. Methods: Two studies were performed in patients 18 to 65 years of age with Primary Insomnia. After a 7-day single-blind placebo run-in, patients were randomized to double-blind treatment with gaboxadol 15 mg (N = 310), 10 mg (N = 308), or placebo (N = 309) over 3 months in Study 1; and gaboxadol 15 mg (N = 304) or placebo (N = 301) over 12 months in Study 2. Treatment was administered at bedtime. The primary efficacy endpoints in each study were change from baseline in patient-reported total sleep time (sTST) and time to sleep onset (sTSO) at month 3. Safety was assessed primarily by adverse event reports. Results: In Study 1, gaboxadol 15 mg significantly improved sTST (difference vs. placebo of 20.4 min, p < 0.01) and sTSO (difference vs. placebo of −9.8 min, p < 0.05) at 3 months, while gaboxadol 10 mg had no significant effects on these measures. In Study 2, gaboxadol 15 mg showed numerical superiority for improvements on sTST (difference vs. placebo of 14.5 min) and sTSO (difference vs. placebo of −4.9 min) at 3 months, but these differences were not significant. In both studies, there was evidence that the efficacy of gaboxadol was more pronounced in women than men. Gaboxadol was generally well tolerated over 3 months in Study 1, and over 12 months in Study 2. Conclusion: Gaboxadol 15 mg showed variable efficacy on measures of sleep duration and onset at 3 months in adult patients with Primary Insomnia in these studies and appeared to be more effective in women than men. Gaboxadol 10 mg was not effective in these studies. (Clinical trial registration numbers: NCT00103818, NCT00095069) Citation: Roth T; Lines C; Vandormael K; Ceesay P; Anderson D; Snavely D.

    The "Deckbiss" with skeletal Class II jaw relationship sometimes presents a considerable therapeutic problem, particularly in the late growth period (DP3U), as regards the coordination of dental and skeletal treatment objectives. An effective treatment approach was demonstrated: a modified Herbst appliance used simultaneously with fixed appliances in the maxilla. The sample comprised 12 male (14.0 +/- 0.9 years old) and 10 female (12.3 +/- 0.4 years old) patients. Correction of the distal occlusion was achieved in all patients by means of the Herbst appliance, which was removed after an average time period of 6.4 +/- 0.2 months. In the mandible the multibracket appliances were then immediately inserted, and Class II elastics were used for retention. Maximum anchorage was required in the maxilla as well as in the mandible. Complete diagnostic records were made at the beginning of the treatment as well as 6 and 12 months later, in order to document skeletal and dental changes. A dental and skeletal Class I relationship was achieved in all cases. A significant improvement was recorded in the vertical jaw base relationship; this was still stable after a period of 12 months. In the dental area in particular, a so-called high-pull headgear effect (intrusion and distalization 16, 26) and intrusion of teeth 34, 44 were registered. Only a minor protrusion of the mandibular incisors was observed. Reinforcement of the bands reduced the failure rate significantly. The Herbst appliance does not represent a standard treatment for Class II. Its indication range is limited.

    Objective: The transition to parenthood, from pregnancy to postpartum period, is a critical process, particularly for couples expecting twins. There is very little literature regarding the links between anxiety, depression, dyadic adjustment, parental stress, and infant temperament spanning from pregnancy to postpartum. This study has two aims: first, to examine whether mothers’ and fathers’ anxiety, depression, and dyadic adjustment, assessed at the sixth month of pregnancy and 3 months postpartum, are associated with infants’ negative affectivity (NA) and parenting stress; second, to examine whether there is any difference between fathers’ and mothers’ levels of parenting stress and perception of the twins’ temperament, as well as to evaluate, separately for mothers and fathers, whether the levels of parenting stress and perception of child temperament differ for each twin. Method: The study participants were 58 parents (29 couples) and their healthy 58 twin babies (51.7% boys, 48.3% girls). Mothers’ ages ranged from 30 to 44 years, (MAge = 36.3 years, SD = 3.2 years), and fathers’ ages ranged from 32 to 52 years, (MAge = 38.2 years, SD = 4.4 years). The parents, during the pregnancy period and 3 months after delivery, filled out the Edinburgh Postnatal Depression Scale, the State-Trait Anxiety Inventory, and the Dyadic Adjustment Scale. Three months after delivery they also filled out the Parenting Stress Index—Short Form and the Infant Behavior Questionnaire Revised. Results: The analyses showed a significant correlation between parental anxiety/depression symptoms and infants’ NA and parenting stress (in both mothers and fathers). Moreover, compared to fathers, mothers reported higher scores on specific dimensions of the infants’ NA, [t(28) = -2.62 and p < 0.05; t(28) = 2.09 and p < 0.05], and parenting stress, [t(28) = 2.19 and p < 0.05; t(28) = 2.23 and p < 0.05], but only for Twin 2. Finally, the results showed that mothers

    A method of the formation of nanoporous structures in metallic materials by pulse-periodic laser treatment was developed. In this study, the multicomponent aluminum-iron brass was considered and the nanoporous structure across the entire cross section of the material with a thickness of 50 μm was formed. The method was implemented using a CO2 laser processing unit. The pulse-periodic laser treatment of the Cu-Zn-Al-Fe alloy with pulse frequency of 5 Hz has led to the formation of nanosized cavities due to accumulation of internal stresses during cyclic heating and cooling at high speeds. It was determined that the pores of a channel type with average widths of 80-100 nm are formed in the central region of the heat-affected zone during laser action with thermocycling. When implementing the chosen conditions of the pulse-periodic laser processing, the localness in depth and area of the physical processes occurring in the heat-affected zone is ensured, while maintaining the original properties of the material and the absence of significant deformations in the rest of the volume. This patented process is perspective for the production not only catalysts for chemical reactions, but for ultrafiltration and microfiltration membranes as well.

  5. Action experience alters 3-month-old infants’ perception of others’ actions

    An intervention facilitated 3-month-old infants’ apprehension of objects either prior to (reach first), or after (watch first) viewing another person grasp similar objects in a visual habituation procedure. Action experience facilitated action perception: reach-first infants focused on the relation between the actor and her goal, but watch-first infants did not. Infants’ sensitivity to the actor’s goal was correlated with their engagement in object-directed contact with the toys. These findings indicate that infants can rapidly form goal-based action representations and suggest a developmental link between infants’ goal directed actions and their ability to detect goals in the actions of others.

    Cystic fibrosis (CF) is a hereditary disease of mucous and sweat glands, which affects the respiratory and gastrointestinal systems. Herein, we describe a 3-month-old girl with a history of recurrent episodes of urinary tract infections that required hospitalization. She was referred to our center at the age of three months, with massive gastroesophageal variceal bleeding. In physical examination, she had clubbing, hepatosplenomegaly, and mild ascites. Laboratory studies revealed high serum levels of liver enzymes and low level of Albumin. As of suspicious to CF, sweat tests were performed twice which confirmed the diagnosis of CF. Gastrointestinal bleeding due to gastroesophageal varices is a rare complication of CF, which could result as a consequence of hepatobiliary involvement of disease. Early diagnosis of CF could prevent severe complications and even death in this group of patients. PMID:27107529

    We compared the antitremor effect of pramipexole, pergolide, or placebo in Parkinson's disease (PD). A double-blind, randomly controlled, parallel protocol was deployed to examine the effects of placebo, pergolide, and pramipexole [doses escalated to 1.5 mg three times daily (t.i.d.) over 3 months] on a compound Tremor Index (TI) and Unified Parkinson's Disease Rating Scale (UPDRS) part III. Thirty PD patients (19 men, 11 women; mean age 69 years, range 54-80 years; mean disease duration 3.9 years, range, 0.5-10 years) participated in the study, with 10 patients in each arm. Six subjects failed to complete the study (4 on pergolide and 2 on placebo). Analysis of covariance demonstrated strong evidence for a treatment effect on both TI and UPDRS III. There was no significant difference between the active treatments on either TI or UPDRS III. Both pergolide and pramipexole were significantly better than placebo. The results indicate that pergolide and pramipexole (1.5 mg t.i.d.) have similar anti-PD tremor and UPDRS III actions that are significantly superior to placebo. Patients on pergolide were more likely to drop out because of adverse events than those on pramipexole.

    Filariasis surveys made during 1962-63 in 5 villages in American Samoa among persons over 5 years of age gave an elephantiasis rate of 3.4%, a microfilarial rate of 26% and a median microfilarial rate (MfD50) of 29. These rates were somewhat higher than those found in surveys made in the same villages among villagers of the same ages some 20 years previously. A mass treatment programme with diethylcarbamazine was then decided on. Preliminary treatment with a single total regimen of 72 mg of the drug per kg of body weight, given in 12 doses of 6 mg/kg, was administered in several villages over a period of 6 months. Among villagers of all ages at the end of 3 years, the microfilarial rate was 7.3% and the MfD50 value was 2. These results appeared to be inadequate for a successful control programme and a periodic mass treatment project of 2 or more regimens of 72 mg/kg to be administered every 2 years was instituted on the Island of Tutuila, to be continued until considered no longer necessary. Surveys made 2 years after the second mass treatment in the villages of Amouli, Amanave, Onenoa, Tula, Alao, Utumea and Alofau, in which 1407 persons were examined, showed that 3 villages were negative for microfilariae, that the average microfilarial rate in all 7 villages was 0.4% and that the MfD50 was 1. These villages were also negative in intensive mosquito surveys for infective-stage larvae of Wuchereria bancrofti. It is suggested that interruption of transmission has been observed in the 3 villages negative for both microfilariae and infective-stage larvae and that, if favourable surveys continue, eradication programmes should be established.

    The treatment of partial nefrectomies is usually performed under a warm ischemic period. Recently, various treatment modalities have become available to perform a partial nefrectomy without clamping off the blood circulation. We have studied three devices in laboratory setting, investigating the thermal and high speed imaging techniques in tissue models and consequently, applying the instruments in the clinic during open procedures especially looking at efficacy and blood loss. The continuous wave 2.0 micron laser of 70 W (Revolix, LISA laser) is used as a fiber delivered knife cutting through circulated tissue with controlled hemostasis for vessels up to 3 mm diameter. The 2 μm wavelength effectively vaporizes tissue water and coagulates the smaller vessels. The Hydro-Jet (ERBE, Germany) uses high pressure (20-80 bar) to ejects a water jet of 40 um diameter at high velocity (10-30 m/s). The parenchyma is resected while vessels are preserved. Consequently, the exposed vessels can be coagulated in a controlled way with minimal blood loss. The water jet showed to induce cavitation bubbles that resect the soft tissue from the matrix leaving the elastic microvessels intact. Various systems are based on bipolar RF technology. We are using the Habib device (Rita 1500X RF generator) to create a coagulation zone around the tumor. Subsequently, the tumor can be resected along the coagulation zone with minimal bleeding. The treatment modalities investigated, have their own advantages and, stand-alone or in combination, can facilitate laparoscopic partial nephrectomies without an ischemic period.

  10. Linear-scaling explicitly correlated treatment of solids: Periodic local MP2-F12 method

    2013-11-21

    Theory and implementation of the periodic local MP2-F12 method in the 3*A fixed-amplitude ansatz is presented. The method is formulated in the direct space, employing local representation for the occupied, virtual, and auxiliary orbitals in the form of Wannier functions (WFs), projected atomic orbitals (PAOs), and atom-centered Gaussian-type orbitals, respectively. Local approximations are introduced, restricting the list of the explicitly correlated pairs, as well as occupied, virtual, and auxiliary spaces in the strong orthogonality projector to the pair-specific domains on the basis of spatial proximity of respective orbitals. The 4-index two-electron integrals appearing in the formalism are approximated via the direct-space density fitting technique. In this procedure, the fitting orbital spaces are also restricted to local fit-domains surrounding the fitted densities. The formulation of the method and its implementation exploits the translational symmetry and the site-group symmetries of the WFs. Test calculations are performed on LiH crystal. The results show that the periodic LMP2-F12 method substantially accelerates basis set convergence of the total correlation energy, and even more so the correlation energy differences. The resulting energies are quite insensitive to the resolution-of-the-identity domain sizes and the quality of the auxiliary basis sets. The convergence with the orbital domain size is somewhat slower, but still acceptable. Moreover, inclusion of slightly more diffuse functions, than those usually used in the periodic calculations, improves the convergence of the LMP2-F12 correlation energy with respect to both the size of the PAO-domains and the quality of the orbital basis set. At the same time, the essentially diffuse atomic orbitals from standard molecular basis sets, commonly utilized in molecular MP2-F12 calculations, but problematic in the periodic context, are not necessary for LMP2-F12 treatment of crystals.

    Background: Platelet-rich plasma (PRP) is defined as an autologous concentration of plasma with a greater count of platelets than that of whole blood. Its action depends on the released growth factors from platelets. It has been investigated and used in numerous fields of medicine. Recently, PRP has received growing attention as a potential therapeutic tool for hair loss. Aims: To evaluate the efficacy and safety of PRP injections in the scalp of patients with androgenetic alopecia. Settings and Design: Prospective cohort study. Materials and Methods: 20 patients, 18 males and 2 females, with androgenetic alopecia were enrolled in the study. PRP was prepared using a single spin method (Regenlab SA). Upon activation, it was injected in the androgen-related areas of scalp. Three treatment sessions were performed with an interval of 21 days and a booster session at 6 months following the onset of therapy. Statistical Analysis: Statistical analysis of the data was performed using the Statistical Package for the Social Sciences (SPSS), version 19.0 (IBM, NY, USA). Results: Hair loss reduced and at 3 months it reached normal levels. Hair density reached a peak at 3 months (170.70 ± 37.81, P < 0.001). At 6 months and at 1 year, it was significantly increased, 156.25 ± 37.75 (P < 0.001) and 153.70 ± 39.92 (P < 0.001) respectively, comparing to baseline. Patients were satisfied with a mean result rating of 7.1 on a scale of 1-10. No remarkable adverse effects were noted. Conclusions: Our data suggest that PRP injections may have a positive therapeutic effect on male and female pattern hair loss without remarkable major side effects. Further studies are needed to confirm its efficacy. PMID:25722600

    The principal objective of our study was to optimise a municipal activated sludge wastewater treatment plant (WWTP) to face high organic flows due to viticulture effluents inputs. Treatment file optimization consisted in testing different treatment lines, changing the number and volume of biological basins and clarifiers, with or without a buffer basin upstream, with a view to achieving a better reduction of COD. The actual WWTP biological stage is composed of two aerated basins whose total volume is 1365 m3. The studied cases are successively, the installation of a single basin of 1365 m3, then of several basins whose total volume remains constant and equal to 1365 m3. Another case was also considered, that of an aerated basin followed by a first clarifier and then, by another aerated basin and a second clarifier. All scenarios presented below were evaluated, for standard dry weather conditions and for high organic load conditions, as encountered during the grape harvest period. The method used was to carry out various simulations, using numerical modelling, and to compare the impact of different process line scenarios and management strategies on the activated sludge WWTP efficiencies.

    Objective: The aim of this prospective study was to compare the periodontal health and the microbiological changes via real-time polymerase chain reaction (PCR) in patients treated with fixed orthodontic appliances and Invisalign® system (Align Technology, Santa Clara, California). Materials and Methods: Seventy-seven patients were enrolled in this study and divided into three groups (Invisalign® group, fixed orthodontic appliances group and control group). Plaque index, probing depth, bleeding on probing were assessed. Total biofilm mass and periodontal pathogens were analyzed and detected via real-time PCR. All these data were analyzed at the T0 (beginning of the treatment) T1 (1-month) and T2 (3 months); and statistically compared using the Mann–Whitney test for independent groups. Results: After 1-month and after 3 months of treatment there was only one sample with periodontopathic anaerobes found in patient treated using fixed orthodontic appliances. The Invisalign® group showed better results in terms of periodontal health and total biofilm mass compared to the fixed orthodontic appliance group. A statistical significant difference (P < 0.05) at the T2 in the total biofilm mass was found between the two groups. Conclusion: Patients undergoing orthodontic treatment with the Invisalign® System show a superior periodontal health in the short-term when compared to patients in treatment with fixed orthodontic appliances. Invisalign® should be considered as a first treatment option in patients with risk of developing periodontal disease. PMID:26430371

    It is difficult to validate statistical software used to assess bioequivalence since very few datasets with known results are in the public domain, and the few that are published are of moderate size and balanced. The purpose of this paper is therefore to introduce reference datasets of varying complexity in terms of dataset size and characteristics (balance, range, outlier presence, residual error distribution) for 2-treatment, 2-period, 2-sequence bioequivalence studies and to report their point estimates and 90% confidence intervals which companies can use to validate their installations. The results for these datasets were calculated using the commercial packages EquivTest, Kinetica, SAS and WinNonlin, and the non-commercial package R. The results of three of these packages mostly agree, but imbalance between sequences seems to provoke questionable results with one package, which illustrates well the need for proper software validation.

  15. Differential changes in self-reported aspects of interoceptive awareness through 3 months of contemplative training

    Interoceptive body awareness (IA) is crucial for psychological well-being and plays an important role in many contemplative traditions. However, until recently, standardized self-report measures of IA were scarce, not comprehensive, and the effects of interoceptive training on such measures were largely unknown. The Multidimensional Assessment of Interoceptive Awareness (MAIA) questionnaire measures IA with eight different scales. In the current study, we investigated whether and how these different aspects of IA are influenced by a 3-months contemplative intervention in the context of the ReSource project, in which 148 subjects engaged in daily practices of “Body Scan” and “Breath Meditation.” We developed a German version of the MAIA and tested it in a large and diverse sample (n = 1,076). Internal consistencies were similar to the English version (0.56–0.89), retest reliability was high (rs: 0.66–0.79), and the MAIA showed good convergent and discriminant validity. Importantly, interoceptive training improved five out of eight aspects of IA, compared to a retest control group. Participants with low IA scores at baseline showed the biggest changes. Whereas practice duration only weakly predicted individual differences in change, self-reported liking of the practices and degree of integration into daily life predicted changes on most scales. Interestingly, the magnitude of observed changes varied across scales. The strongest changes were observed for the regulatory aspects of IA, that is, how the body is used for self-regulation in daily life. No significant changes were observed for the Noticing aspect (becoming aware of bodily changes), which is the aspect that is predominantly assessed in other IA measures. This differential pattern underscores the importance to assess IA multi-dimensionally, particularly when interested in enhancement of IA through contemplative practice or other mind–body interventions.

    2011-01-01

    Background: To describe the prescription patterns of analgesics during the last 3 months of life in lung cancer and to determine the associated factors. Methods: Data on lung cancer patients (N=10 202) who died during 2000–2008 were extracted from the General Practice Research Database (GPRD). This database records prescriptions of patients received from UK general practices (GP), but not those from non-GP routes. Prescription prevalences were estimated. The associated factors were investigated using log-binomial regression. Results: The overall prescription prevalences were 50.4% (95% confidence interval (CI): 49.4–51.4%) for level 1 (e.g., paracetamol), 34.1% (95% CI: 33.2–35.0%) for level 2 (weak opioids), and 55.5 % (95% CI: 54.5–56.4%) for level 3 analgesics (strong opioids). Prescription prevalence of analgesics of all levels showed an increasing trend over the period 2000–2008 (annual increases range: 1.1–1.5%) but a decreasing trend with age (average decrease per group range: −5.8 to −1.8%). Patients in the older age groups were less likely to be prescribed level 3 analgesics than those in the younger age groups (PR‘90+' vs ‘<50'=0.55 (95% CI: 0.45–0.67); PR‘80−89' vs ‘<50'=0.73 (95% CI: 0.66–0.79); PR‘70−79' vs ‘<50'=0.84 (95% CI: 0.77–0.90)). Conclusion: Analgesics have been increasingly prescribed in lung cancer. However, analgesics, especially at level 3, were relatively under-prescribed to people older than 70 years, warranting further investigation. PMID:21540860

    2011-01-01

    Cryopyrin-associated periodic syndrome (CAPS) include a group of rare autoinflammatory disorders, the spectrum of which ranges from the mildest form, ie, familial cold autoinflammatory syndrome to more severe phenotypes, ie, Muckle-Wells syndrome, and chronic infantile neurological cutaneous and articular syndrome, also known as neonatal-onset multisystem inflammatory disease. Three interleukin (IL)-1 antagonists have been tested in adults and children with CAPS, ie, anakinra, a recombinant homolog of the human IL-1 receptor antagonist; rilonacept, a fusion protein comprising the extracellular domains of IL-1 receptor I and the IL-1 adaptor protein, IL-1RAcP, attached to a human immunoglobulin G molecule; and canakinumab, the anti-IL-1β monoclonal antibody. Following rapid clinical development, rilonacept and canakinumab were approved by both the US Food and Drug Administration and the European Medicines Agency for use in adults and children. This review describes how the study of CAPS has helped us to understand better the way the innate immune system works, the pathogenesis of autoinflammatory syndromes, and the key role of IL-1. It also reviews the effects of IL-1 blockade in CAPS and other disorders, in particular systemic juvenile idiopathic arthritis, adult-onset Still’s disease, and gout. Finally, this review covers some issues addressed by very recent and ongoing work regarding treatment indications, from orphan diseases to common disorders, continuous versus intermittent treatment, the pharmacokinetics, pharmacodynamics, and optimal dosages of the different drugs, as well as the need for Phase IV trials, exhaustive registries, and long-term follow-up of several patient cohorts.

  18. Anakinra and related drugs targeting interleukin-1 in the treatment of cryopyrin-associated periodic syndromes

    PubMed Central

    Bachove, Inessa; Chang, Christopher

    2014-01-01

    Anakinra is an interleukin (IL) receptor antagonist that works by blocking the biological activity of IL-1 by competitively inhibiting binding of IL-1 to the type 1 interleukin receptor. IL-1 production is induced in response to inflammatory stimuli and mediates various physiological mechanisms, including inflammation and immunological reactions. Patients with neonatal onset multisystem inflammatory disease (NOMID) produce excess IL-1β, a major proinflammatory cytokine that regulates innate immune responses. Anakinra binds competitively and this results in a rapid reduction in disease severity. NOMID, also known as chronic infantile neurologic, cutaneous, articular syndrome, is the most severe clinical phenotype in the spectrum of cryopyrin-associated periodic syndromes. It is characterized by cutaneous symptoms, arthropathy, and central nervous system involvement. Extensive studies in patients with NOMID have led to advances in characterizing the extent of organ-specific involvement and damage that occurs with chronic overproduction of IL-1β. NOMID is caused predominantly by mutations in the NLRP3/CIAS1 gene that encodes for the protein cryopyrin, leading to activation of the “NLRP3 inflammasome complex”. This in turn regulates the maturation and secretion of the inflammatory cytokine, IL-1β. The clinical value of IL-1β has been demonstrated by the positive response of patients after treatment with anakinra, with rapid improvement in clinical symptoms, markers of inflammation, and a significant decrease in major organ manifestations.

    About 21 times of cattle epidemic with rather strong infectivity happened during the Han-Tang Period, including 6 in the Eastern Han Dynasty, 2 in the Jin Dynasty, 4 in the Southern and Northern Dynasties, 8 in the Tang Dynasty and 1in the Five Dynasty. Most of them were spread along the Yellow River and the northern region of the Huai River. The type of cattle epidemic included the acute cattle plague, cattle bovine mange, cattle yellow fever and cattle rotten hoof disease, etc. Its occurrence and prevalence brought a serious influentce on the society of the Han and Tang Dynasties, causing massive mortality of farm cattle, and then the shortage of animal power, and threatening the agriculture, which drew the attention of the governments, physicians, agriculturists, astrologists and Taoists. The medical measures and economic measures were adopted for the prevention and treatment of cattle epidemic. Especially, prescriptions in the books of medicine and agriculture exerted positive effects on the containment of cattle epidemic. On the other hand, its prevalence and the mass mortality of farm cattle, in a way, promoted, to certain extent, the improvement of the government's function of relief, the updating of the methods of agriculture and the creation of new farm tools, and being regarded as a main cause for the technological innovation of agriculture.

    Visit-to-visit variability (VVV) in blood pressure (BP) has been shown to be a predictor of cardiovascular events. It is unknown whether CR can improve VVV in BP as well as reducing BP. We enrolled 84 patients who had cardiovascular disease (CVD) and participated in a 3-month CR program. We measured systolic and diastolic BP (SBP and DBP), pulse pressure (PP), and heart rate (HR) before exercise training at each visit and determined VVV in BP or HR expressed as the standard deviation of the average BP or HR. Patients who had uncontrolled BP at baseline and who did not change their antihypertensive drugs throughout the study period showed a significant reduction of both SBP and DBP with a decrease in PP after 3 months. Patients who did not change their antihypertensive drugs were divided into larger (L-) and smaller (S-) VVV in the SBP groups and L- and S-VVV in the DBP groups according to the average value of VVV in SBP or DBP. In the L-VVV in the SBP and DBP groups, VVV in SBP and DBP in the 1st month was significantly decreased after the 3rd month in both groups. HR at baseline was significantly decreased after 3 months. In addition, CR induced a significant increase in the level of high-density lipoprotein cholesterol (HDL-C) in blood. In conclusion, CR improved VVV in BP in patients with L-VVV in BP and evoked a significant reduction in HR and an increase in HDL-C. These effects due to the CR program may be cardioprotective.

    Small intestinal bacterial overgrowth (SIBO) can partly explain irritable bowel syndrome (IBS), and rifaximin has been observed to improve abdominal symptoms in nonconstipated IBS patients. However, there are few reports on the association of the rifaximin treatment periods with the results of a lactulose breath test (LBT). Therefore, we performed a retrospective review of patient charts to investigate the relation between the rifaximin treatment periods with LBT results in nonconstipated IBS patients. We also evaluated the time to achieve a symptomatic improvement in the IBS patients as compared to the changes in the LBT. We reviewed the charts for patients who showed IBS symptoms with documented positive results for LBT during their initial visit and who had a follow-up LBT after treatment with rifaximin. The LBT values were compared to the subjects' symptom scores. A total of 102 subjects had a follow-up LBT to assess LBT normalization. The subjects were divided into groups according to treatment periods of 4 weeks (n = 36), 8 weeks (n = 43), and 12 weeks (n = 23). The groups with a longer treatment exhibited an increase in the hydrogen gas value at 90 min and its sum during 90 min at the initial LBT. There were significant differences in hydrogen gas value at 90 min and in its sum during 90 min at the initial LBT between the groups treated for 4 and 12 weeks. The most significant treatment response was observed during the first 4 weeks for all treatment groups. Symptomatic improvement occurred earlier than LBT normalization in the treatment period over 4 weeks. The results indicate that different rifaximin treatment periods are needed in accordance with LBT levels to effectively eradicate SIBO. PMID:26028929

    Exposure to maternal depression increases risks for altered mother-infant interactions. Serotonin reuptake inhibitor (SRI) antidepressants are increasingly prescribed to manage antenatal maternal illness. The impact of SRIs on early mother-infant interactions was unknown. Three-month-old infants of 32 depressed mothers treated with SRI medications during pregnancy and 43 non-medicated mothers were studied. Using an established face-to-face mother-infant interaction paradigm, dyad interactions were studied with and without a toy. Videotaped sessions yielded 4 measures: maternal sensitivity, dyadic organization, infant readiness to interact, and maternal interruptive behaviors. Even with prenatal SRI treatment, depressed mothers interrupted their infants more during toy play. In the absence of prenatal SRI treatment, maternal postnatal depression adversely influenced infant behavior. Higher levels of maternal depression symptoms at 3 months predicted poorer infant readiness to interact during the toy session. Conversely, in the SRI-exposed group, higher prenatal depression scores predicted greater infant readiness to interact at 3 months. Increased infant readiness with SRI exposure suggests a "fetal programming effect" whereby prenatal maternal mood disturbances shaped a future response to a postnatal depressed maternal environment.

    Calfhood disease is an important problem on many dairy operations that can have substantial effects on heifer survival and productivity, and has economic and welfare impacts. Neonatal calf diarrhea (NCD) and bovine respiratory disease (BRD) are the most common causes of morbidity and mortality in young dairy cattle. The objective of this observational study was to investigate factors associated with the risks of morbidity and mortality, and with growth, in commercial dairy heifers calves. A total of 2874 heifer calves from 19 commercial dairy farms in Minnesota and Ontario were enrolled at 1-7 days of age and followed for approximately 3 months. Using cut-points of serum total protein of 5.2 and 5.7 g/dl, the incidences of failure of transfer of passive immunity (FTPI) were 11 and 32%, respectively. A cut-point of 5.7 g/dl was the most predictive of BRD before 5 weeks of age (sensitivity=40%, specificity=69%). The positive predictive value was poor (PPV=18%), but the negative predictive value was good (NPV=87%). A cut-point of 5.2g/dl was most predictive of death before 5 weeks of age (sensitivity=27%, specificity=89%, PPV=5%, NPV=98%). Serum total protein during the first week of life was a poor predictor of NCD. Over 23% of calves were treated for diarrhea. Risk factors were weight at enrollment, other diseases before 2 weeks of age, and an interaction between season of birth and herd-level incidence of NCD. Almost 22% of calves were treated at least once for BRD. Factors associated with an increased risk of BRD included herd-level incidence of BRD, season of birth, navel dipping, other diseases before 2 weeks of age, failure of transfer of passive immunity, and manual control of temperature in pre-weaning housing. Administration of supplemental antibody products at birth was associated with a reduced incidence of BRD. Overall mortality was 3.5%. Risk of mortality was increased by treatment for BRD and other diseases. The mean average weight gain was 0.95 kg

    Metabolic surgery has been shown to provide better glycemic control for type 2 diabetes than conventional therapies. Still, the outcomes of the surgery are variable, and prognostic markers reflecting the metabolic changes by the surgery are yet to be established. NMR-based plasma metabolomics followed by multivariate regression was used to test the correlation between the metabolomic profile at 7-days after surgery and glycated hemoglobin (HbA1c) levels at 3-months (and up to 12 months with less patients), and to identify the relevant markers. Metabolomic profiles at 7-days could differentiate the patients according to the HbA1c improvement status at 3-months. The HbA1c values were predicted based on the metabolomics profile with partial least square regression, and found to be correlated with the observed values. Metabolite analysis suggested that 3-Hydroxybutyrate (3-HB) and glucose contributes to this prediction, and the [3-HB]/[glucose] exhibited a modest to good correlation with the HbA1c level at 3-months. The prediction of 3-month HbA1c using 7-day metabolomic profile and the suggested new criterion [3-HB]/[glucose] could augment current prognostic modalities and help clinicians decide if drug therapy is necessary.

    We investigated enforcement of mental health benefits provided by California Medicaid's Early Periodic Screening, Diagnosis, and Treatment (EPSDT) program. Enforcement, compelled by a consumer-driven lawsuit, resulted in an almost 4-fold funding increase over a 5-year period. We evaluated the impact of enforcement on outpatient treatment intensity (number of visits per child) and rates of emergency care treatment. Using fixed-effects regression, we examined the number of outpatient mental health visits per client and the percentage of all clients using crisis care across 53 autonomous California county mental health plans over 32 three-month periods (quarters; emergency crisis care rates) and 36 quarters (out-patient mental health visits). Enforcement of EPSDT benefits in accordance with federal law produced favorable changes in patterns of mental health service use, consistent with policy aims.

    Light transport in periodic waveguides coupled to two-level atoms is investigated theoretically. By using optical Bloch equations and a photonic modal formalism, we derive a convenient semi-analytical expression for calculating the scattering matrix of single atoms trapped in periodic waveguides. The expression that holds for both photonic and plasmonic waveguides represents a basic building block toward the study of collective effects arising from photon-mediated multi-atom interactions in periodic waveguides.

    Opioid maintenance treatment (OMT) is the most widely used treatment for opioid dependence. Maintenance programmes differ in various aspects and may also change over time. This paper investigates the changes in treatment practices within a national OMT programme during a 10 year period (2002-2011), especially with regard to the prescribing of methadone and buprenorphine. Data (n=34,001) were collected by annual assessments questionnaires. In 2002, only 16% of the OMT patients received buprenorphine as their maintenance medication. By 2011 this percentage had increased significantly (p<.001) to 50.3%. In the same period the number of patients more than tripled (from 1,984 to 6,640, p<.001), and programme attrition rates decreased (p=.020). This relatively rapid shift is a part of the increasing reliance of addiction medicine upon a range of medications administered by different routes which has not been previously charted within a national treatment programme.

    Efavirenz (EFV) is a nonnucleoside reverse transcriptase inhibitor approved worldwide for the treatment of HIV in adults and children over 3 years of age or weighing over 10 kg. Only recently EFV was approved in children over 3 months and weighing at least 3.5 kg in the United States and the European Union. The objective of this analysis was to support the selection of an appropriate dose for this younger pediatric population and to explore the impact of CYP2B6 genetic polymorphisms on EFV systemic exposures. A population pharmacokinetic (PPK) model was developed using data from three studies in HIV-1-infected pediatric subjects (n = 168) and one study in healthy adults (n = 24). The EFV concentration-time profile was best described by a two-compartment model with first-order absorption and elimination. Body weight was identified as a significant predictor of efavirenz apparent clearance (CL), oral central volume of distribution (VC), and absorption rate constant (Ka). The typical values of efavirenz apparent CL, VC, oral peripheral volume of distribution (VP), and Ka for a reference pediatric patient were 4.8 liters/h (4.5 to 5.1 liters/h), 84.9 liters (76.8 to 93.0 liters), 287 liters (252.6 to 321.4 liters), and 0.414 h(-1) (0.375 to 0.453 h(-1)), respectively. The final model was used to simulate steady-state efavirenz concentrations in pediatric patients weighing <10 kg to identify EFV doses that produce comparable exposure to adult and pediatric patients weighing ≥10 kg. Results suggest that administration of EFV doses of 100 mg once daily (QD) to children weighing ≥3.5 to <5 kg, 150 mg QD to children weighing ≥5 to <7.5 kg, and 200 mg QD to children weighing ≥7.5 to <10 kg produce exposures within the target range. Further evaluation of the impact of CYP2B6 polymorphisms on EFV PK showed that the identification of CYP2B6 genetic status is not predictive of EFV exposure and thus not informative to guide pediatric dosing regimens.

    Techniques that help patients stop smoking should also reduce their exposure to agents such as nicotine. The mean plasma nicotine levels in 50 subjects while they were still smoking and then while they were chewing pieces of gum containing either 2 or 4 mg of nicotine over a 12-week period of abstinence were 35, 9 and 23 ng/mL (217, 56 and 143 nmol/L) respectively. A small number of subjects given an unlimited supply of gum used 14 to 24 pieces of 4-mg gum daily and had plasma nicotine levels exceeding the levels achieved while smoking. There were no acute symptoms necessitating medical intervention associated with these excessive levels. Side effects were uncommon and usually controllable. When simple dosage rules are followed people who chew nicotine gum for a few months to stop smoking lower their exposure to nicotine. PMID:6478344

    Objective To describe antidepressant (AD) use in the treatment of major depressive disorder during a period of economic crisis. Patients and methods This was a retrospective, observational study using population-based databases. Two periods were considered: 1) 2008–2009, precrisis, and 2) 2012–2013, economic crisis. Certain inclusion/exclusion criteria were taken into account for the study (initiation of AD treatment). Patients were followed up for 12 months. The main measures were use (defined daily doses), epidemiologic measures, strategies used and treatment persistence, referrals, and use of resources. Statistical significance was set at P<0.05. Results In the precrisis period, 3,662 patients were enrolled, and 5,722 were enrolled in the period of economic crisis. Average age was 58.8 years and 65.4% were women. Comparing the two periods, major depressive disorder prevalence was 5.4% vs 8.1%, P<0.001. During the period of economic crisis, AD use rose by 35.2% and drug expenditures decreased by 38.7%. Defined daily dose per patient per day was 10.0 mg vs 13.5 mg, respectively, P<0.001. At 12-month follow-up, the majority of patients (60.8%) discontinued the treatment or continued on the same medication as before, and in 23.3% a change of AD was made. Conclusion Primary health care professionals are highly involved in the management of the illness; in addition, during the period of economic crisis, patients with major depressive disorder showed higher rates of prevalence of the illness, with increased use of AD drugs.

    Evidence suggests that short-term animal exposures to synthetic amorphous silicas (SAS) and crystalline silica can provide comparable prediction of toxicity to those of 90-day studies, therefore providing the opportunity to screen these types of substances using short-term rather than 90-day studies. To investigate this hypothesis, the inhalation toxicity of three SAS, precipitated silica Zeosil 45, silica gel Syloid 74, and pyrogenic silica Cab-O-Sil M5 was studied in Wistar rats. Rats were exposed nose-only to concentrations of 1, 5 or 25mg/m(3) of one of the SAS 6h a day for five consecutive days. Positive controls were exposed to 25mg/m(3) crystalline silica (quartz dust), negative controls to clean air. Animals were necropsied the day after the last exposure or 1 or 3 months later. All exposures were tolerated without serious clinical effects, changes in body weight or food intake. Differences in the effects associated with exposure to the three types of SAS were limited and almost exclusively confined to the 1-day post-exposure time point. Silicon levels in tracheobronchial lymph nodes were below the detection limit in all groups at all time points. Silicon was found in the lungs of all high concentration SAS groups 1-day post-exposure, and was cleared 3 months later. Exposure to all three SAS at 25mg/m(3) induced elevations in biomarkers of cytotoxicity in bronchoalveolar lavage fluid (BALf), increases in lung and tracheobronchial lymph node weight and histopathological lung changes 1-day post-exposure. Exposure to all three SAS at 5mg/m(3) induced histopathological changes and changes in BALf only. With all three SAS these effects were transient and, with the exception of slight histopathological lung changes at the higher exposure levels, were reversible during the 3-month recovery period. No adverse changes were observed in animals exposed to any of the SAS at 1mg/m(3). In contrast, with quartz-exposed animals the presence of silicon in the lungs was

We translated into Italian and validated the Breastfeeding Self-Efficacy Scale Short Form (BSES-SF) and investigated its predictive ability and its relation with postpartum depression symptoms.BSES-SF and Edinburgh Postnatal Depression Scale (EPDS) were administered 2 to 3 days after delivery to 122 mothers. Breast-feeding was assessed at 3 months.The BSES-SF displayed good validity (receiver operating characteristic area = 0.69) for predicting full breast-feeding at 3 months. In multivariate analysis, the probability of full breast-feeding increased 2.4% for 1-point increase of BSES-SF. The BSES-SF and EPDS scores were inversely correlated. BSES-SF is a useful tool to identify the risk of early breast-feeding attrition.

    BACKGROUND Progressive resistance training (PRT) can improve strength and function in people with chronic stroke, but less is known about whether this intervention is safe and beneficial during the first 3 months following stroke. OBJECTIVE To systematically review the evidence about the safety and effectiveness of PRT to improve activity in people within the first 3 months after stroke. METHODS After database searching and selection of studies a risk of bias assessment was conducted. Data for the primary outcome of safety was synthesised descriptively and meta-analyses for other outcomes were conducted using a random effects model. RESULTS The quality of the 5 included studies ranged from good to excellent (mean 24.2, range 20-28). For the trials investigating adverse events, none reported any significant increase in events after PRT. There was high level evidence that PRT had little or no effect on strength (SMD (standardized mean difference) 0.17, 95% CI -0.16 to 0.50, I(2) = 0%). There were no significant benefit for upper limb function (SMD 0.11, 95% CI -0.41 to 0.63, I(2) = 0%) and mobility (SMD 0.11, 95% CI -0.21 to 0.43, I(2) = 27%) after PRT compared with controls. CONCLUSIONS There was no evidence reported that PRT is unsafe in people within the first 3 months after stroke, although there was a lack of reporting about adverse events. The lack of demonstration of effect in improving muscle strength and activity suggests there is insufficient evidence to recommend the prescription of PRT for people within the first 3 months after stroke.

    Kimchi, a traditional fermented food regularly consumed in Korea, contains various types of antimicrobial compounds. Among the tested compounds present in common spices used in Kimchi, quercetin showed the highest selectivity index against influenza A virus (IAV) H1N1. In this study, the effect of pretreatment and periodic treatment with quercetin against IAV in Madin-Darby canine kidney cells was observed. Compared to pretreatment, periodic treatment resulted in significantly higher cell viability but lower relative expression of the IAV PA gene and total apoptosis and cell death. To explain the mechanisms underlying the antiviral effects of quercetin treatment, a comparative proteomic analysis was performed in four samples (mock, quercetin-treated, IAV-infected, and quercetin-treated IAV-infected). Among the 220 proteins, 56 proteins were classified nonhierarchically into three clusters and were differentially modulated by quercetin treatment in IAV-infected cells. Post-translational modifications were identified in 68 proteins. In conclusion, periodic treatment with quercetin is effective in reducing IAV infection, and differentially regulates the expression of key proteins, including heat shock proteins, fibronectin 1, and prohibitin to reduce IAV replication.

    Doxazosin, an alpha(1)-adrenergic receptor inhibitor, is commonly administered to patients with type 2 diabetes, hypertension and nephropathy. The impact of 3 months' doxazosin therapy on the prevalence of activated and regulatory T lymphocytes was analysed in this pilot study of men with type 2 diabetes (n = 10) who received doxazosin 4 mg/day in addition to their ongoing therapy. The prevalence of CD4(+), CD8(+), CD25(+) and CD69(+) cells at baseline and after 3 months of add-on therapy was determined. The prevalence of regulatory T-cells was detected by two different approaches: forkhead box P3 (FoxP3) positivity; and the number of CD4(+)CD25(+high) cells. During 3 months of doxazosin therapy, patients' blood pressure, blood glucose control and lipid profiles all significantly improved. Simultaneously, the prevalence of activated T-cells (CD4(+)CD69(+) and CD8(+)CD69(+) cells) decreased, whereas that of regulatory T-cells increased. These results indicate an immunomodulatory action of doxazosin in type 2 diabetic patients.

    The aim of this study was to assess the rate of defaulting from treatment among tuberculosis patients diagnosed in the Netherlands in the period 1993-1997, whether risk groups for defaulting can be identified at the start of treatment and the trend of defaulting over time. The Netherlands Tuberculosis Register provided data on all patients diagnosed in the Netherlands during the period 1993-1997. Defaulting probabilities were determined using Kaplan-Meier survival analysis and risk factors were identified with Cox's proportional hazard analysis. Of 7,529 patients with reported treatment outcome, 718 (10%) defaulted or left the country within 1 yr after starting treatment. Defaulting probabilities were 9% (95% confidence interval (CI) 8-10%) among 5,256 patients in low-risk groups, 17% (95% CI 14-19%) among 1,437 asylum seekers and 29% (95% CI 24-34%) among 836 patients in other high-risk groups (other recent immigrants, illegal immigrants, the homeless, prisoners and nationals from Eastern Europe). Defaulting probabilities decreased over time from 12% in 1993 to 7% in 1997. Risk groups for defaulting can be recognized at the start of treatment. The decreasing defaulting probabilities were probably due in part to shortening treatment from 9 to 6 months and improved follow-up of asylum seekers. However, additional measures are needed to reduce defaulting among the homeless, recent immigrants, illegal immigrants and prisoners.

    This study tested the hypothesis that different doses of nandrolone decanoate (ND) will cause changes in the estrous cycle and ovarian tissue of adult rats; and investigated the duration of the recovery period that is sufficient to restore the damage in the animals treated with different doses. Wistar rats were treated with ND at doses of 1.87, 3.75, 7.5 and 15 mg/kg body weight, or received mineral oil (control group) for 15 days, subcutaneously. All animals were divided into three groups according to the treatment periods: (i) ND treatment for 15 days; (ii) ND treatment followed by a 30-day recovery; and (iii) ND treatment followed by a 60-day recovery. Estrous cycle was monitored daily, and at the end of each period, the animals were euthanized for histopathological analysis. During ND treatment and after 30-day recovery, all animals exhibited persistent diestrus. After a 60-day recovery, persistent diestrus was only maintained in the group that had received the highest dose. Ovarian weight was decreased significantly after the 30-day recovery, regardless of ND doses, compared with the control group. There was a reduction (P < 0.05) in the number of corpora lutea and antral and growing follicles, in contrast to an increase (P < 0.05) in atretic follicles in a dose- and time-dependent manner. Remarkable histopathological changes occurred in the ovaries of all ND-treated groups. In conclusion, the different doses of ND caused changes in the estrous cycle and ovarian tissue of rats, and recovery periods (30 and 60 days) were insufficient to completely restore the damage in the animals treated with the highest dose.

    Tumor necrosis factor receptor-associated periodic syndrome (TRAPS) is an autosomal dominant autoinflammatory disease linked to chromosome 12p13 and, more specifically, with mutations within the tumor necrosis factor receptor superfamily, member 1A gene (TNFRSF1A gene). It is characterized by the presence of fever, abdominal pain, myalgia, arthralgia or arthritis, and skin rash. In this report, we describe the case of a patient with tumor necrosis factor receptor-associated periodic syndrome (TRAPS) treated successfully with the anti-interleukin-6 (anti-IL-6) receptor monoclonal antibody tocilizumab, while treatment with anti-TNF α etanercept and infliximab had both failed.

    The recent availability of human induced pluripotent stem cells (hiPSCs) holds great promise as a novel source of human-derived neurons for cell and tissue therapies as well as for in vitro drug screenings that might replace the use of animal models. However, there is still a considerable lack of knowledge on the functional properties of hiPSC-derived neuronal networks, thus limiting their application. Here, upon optimization of cell culture protocols, we demonstrate that both spontaneous and evoked electrical spiking activities of these networks can be characterized on-chip by taking advantage of the resolution provided by CMOS multielectrode arrays (CMOS-MEAs). These devices feature a large and closely-spaced array of 4096 simultaneously recording electrodes and multi-site on-chip electrical stimulation. Our results show that networks of human-derived neurons can respond to electrical stimulation with a physiological repertoire of spike waveforms after 3 months of cell culture, a period of time during which the network undergoes the expression of developing patterns of spontaneous spiking activity. To achieve this, we have investigated the impact on the network formation and on the emerging network-wide functional properties induced by different biochemical substrates, i.e., poly-dl-ornithine (PDLO), poly-l-ornithine (PLO), and polyethylenimine (PEI), that were used as adhesion promoters for the cell culture. Interestingly, we found that neuronal networks grown on PDLO coated substrates show significantly higher spontaneous firing activity, reliable responses to low-frequency electrical stimuli, and an appropriate level of PSD-95 that may denote a physiological neuronal maturation profile and synapse stabilization. However, our results also suggest that even 3-month culture might not be sufficient for human-derived neuronal network maturation. Taken together, our results highlight the tight relationship existing between substrate coatings and emerging network

    This study explored components of a model of transition to being the mother of a new infant during an infant's first 3 months. Personal and situational conditions and maternal problem-solving factors (issue formulating and the use of help with issues) that may influence transition markers (maternal appraisal of problem-solving competence and evaluation of parenting) were examined for two study periods: the first 30 days postpartum and the next 60 days. For the second study period, variables contributing to maternal attention to infant growth, development and temperament (knowing issues) were also explored. Questionnaires and a daily log kept by 62 mothers of healthy term infants were data sources. Everyday supports (situational condition) contributed to use of lay help for the second period. Caretaking issues positively influenced use of clinician help throughout the study. The number of knowing issues a mother formulated contributed positively to problem-solving competence and to parenting evaluation; the use of problem-solving help had no effect. More clinician help received during the first month meant higher need for maternal action for both knowing and caretaking issues in the second and third months. Further study of the mechanisms of these relationships and examination of factors contributing to shifts in the transition process are needed. PMID:1556329

    The influence of glucocorticoids on the composition and mineral/organic content of the mandible in tested animals after recovery and healing phase was investigated in this work. The results of FTIR analysis demonstrated that bone tissue composition was changed after glucocorticoid treatment. The increase of calcium, magnesium, phosphorus content and mineral part of bones was statistically significant in recovery phase and in treatment phase that included calcitonin and thymus extract. Some changes also happened in the organic part of the matrix, as indicated by intensity changes for already present IR bands and the appearance of new IR bands in the region 3500-1300 cm-1.

    Cryscor is a periodic post-Hartree-Fock program based on local functions in direct space, i.e., Wannier functions and projected atomic orbitals. It uses atom centered Gaussians as basis functions. The Hartree-Fock reference, as well as symmetry information, is provided by the Crystal program. Cryscor presently features an efficient and parallel implementation of periodic local second order Møller-Plesset perturbation theory (MP2), which allows us to study 1D-, 2D- and 3D-periodic systems beyond 1000 basis functions per unit cell. Apart from the correlation energy also the MP2 density matrix, and from that the Compton profile, are available. Very recently, a new module for calculating excitonic band gaps at the uncorrelated Configuration-Interaction-Singles (CIS) level has been added. Other advancements include new extrapolation techniques for calculating surface adsorption on semi-infinite solids. In this paper the diverse features and recent advances of the present Cryscor version are illustrated by exemplary applications to various systems: the adsorption of an argon monolayer on the MgO (100) surface, the rolling energy of a boron nitride nanoscroll, the relative stability of different aluminosilicates, the inclusion energy of methane in methane-ice-clathrates, and the effect of electron correlation on charge and momentum density of α-quartz. Furthermore, we present some first tentative CIS results for excitonic band gaps of simple 3D-crystals, and their dependence on the diffuseness of the basis set. PMID:22334044

    Background Cardiovascular disease (CVD) is a common problem of middle-aged and older adults. Increased arterial stiffness is a CVD risk factor. Whole-body vibration (WBV) is a simple and convenient exercise for middle-aged and older adults; however, there have been few studies investigating the effect of WBV on arterial stiffness. This study mainly investigated the effect of WBV on arterial stiffness in middle-aged and older adults. Methods A total of 38 (21 women and 17 men) middle-aged and elderly subjects (average age, 61.9 years) were randomly divided into the WBV group and the control group for a 3-month trial. The WBV group received an intervention of 30 Hz and 3.2 g WBV in a natural full standing posture at a sports center. The brachial–ankle pulse wave velocity (baPWV), a marker of systemic arterial stiffness, and blood pressure and heart rate were measured before and after the intervention. Results After 3 months, there were no significant changes in blood pressure or heart rate in both groups. However, the bilateral baPWV was significantly reduced in the WBV group (decreased by 0.65 m/second [P=0.014]; 0.63 m/second [P=0.041] in either side), but not in the control group. The comparison between the two groups was not statistically significant. Conclusion This study found that 3 months of WBV had a positive effect on arterial stiffness in middle-aged and older adults and could therefore be regarded as a supplementary exercise. Larger-scale studies are needed to confirm the effects of WBV in the future. PMID:24872684

    Background IgE-mediated cow's milk allergy (CMA) is one of the most common food allergies in infants. It is still controversial whether the early introduction of cow's milk formula (CMF) prevents the development of CMA. Objective We aimed to evaluate the duration and frequency of CMF ingestion as compere with exclusive breast-fed for preventing CMA in high-risk infants. Methods We enrolled the patients diagnosed with hen's egg allergy by an oral food challenge. A questionnaire was completed by the caregivers of the patients regarding the timing of introduction and discontinuation of CMF, and the frequency of CMF ingestion. Based on the information, we analyzed the relationship between the duration and frequency of CMF ingestion and the development of CMA at 3–24 months of age. Results Three hundred seventy-four patients were analyzed; 171 were diagnosed with CMA (45.7%). The analyzed patients (n = 374) were categorized into the following subgroups: exclusively breast-fed (breast-fed group, n = 75); discontinued ingestion of CMF before 3 months of age (temporary group, n = 177); continuous ingestion of CMF, but not daily, up to 3 months of age (nondaily group, n = 47); continuous ingestion of CMF at least once daily (daily group, n = 75). The incidence of developing CMA between the breast-fed group and temporary group did not show any statistical difference. Nondaily group and daily group had significantly lower incidence of developing CMA in comparison to the breast-fed group (nondaily group odds ratio 0.43; p = 0.02, daily group odds ratio 0.11; p < 0.001). Conclusion Ingestion of CMF during the first 3 months of life might prevent the development of CMA in high-risk infants. PMID:27803880

    Purpose Postnatal depression (PND) rates in low-resource countries have reached levels between 4.9% and 59%. Maternal mental health has not been researched in Sudan, and there are no existing statistics on prevalence or significant risk factors for PND. Consequently, no screening test has been validated to screen for PND at the primary health care level. This study investigates the 3 months prevalence of PND and validates the Edinburgh Postnatal Depression Scale (EPDS) against the Mini-International Neuropsychiatric Interview (MINI). Methodology Pregnant Sudanese women in the second and third trimesters were recruited to the study during routine antenatal care visits in two major maternity hospitals in Khartoum state. They were screened for PND at 3 months postpartum using the EPDS. Test positive women were matched with test negative women according to nearest date of birth. A clinical psychologist verified their depression status using the MINI. Results The follow-up rate was 79%. At a cutoff point of ≥12, the 3 months prevalence of PND was 9.2%. The sensitivity and specificity of the EPDS were 89% and 82%, respectively. The EPDS and MINI showed a strong positive relationship (odds ratio =36). The positive predictive value and negative predictive value, using this study’s prevalence, were 33% and 98.7%, respectively. The receiver operator characteristic analysis showed an area under the curve of 0.89. The cut-off point ≥12 was the most acceptable point as it had the lowest number needed to diagnose (1.4) and a false-positive rate of 18%. Conclusion The EPDS is a valid tool for screening for PND on a Sudanese population. It was accepted, easily administered, and understood by postnatal women. Health care personnel, especially village midwives, should be trained on screening and referral of depressed women for clinical evaluation and management. Due to limited resources available in Sudan, shorter screening tests need to be validated in the future. PMID

    Very preterm (VPT) infants are hospitalized in the Neonatal Intensive Care Unit (NICU) and exposed to varying levels of skin-breaking procedures (pain-related stress), even in absence of severe clinical conditions. Repeated and prolonged pain exposure may alter hypothalamic-pituitary-adrenal (HPA) axis reactivity in VPT infants. During the post-discharge period, altered HPA axis reactivity has been documented in response to non-social stressors, using salivary cortisol as a biomarker. However, little is known about the effects of NICU pain-related stress on subsequent HPA axis reactivity to socio-emotional stress in infants. We examined the relationship between pain-related stress in NICU and HPA axis reactivity (i.e., salivary cortisol reactivity) to an age-appropriate socio-emotional condition in 37 healthy VPT infants compared to 53 full-term (FT) controls. The number of skin-breaking procedures was obtained across NICU stay for VPT infants. At 3 months (corrected age for prematurity), all infants participated in the maternal Face-to-Face Still-Face (FFSF) procedure, in order to assess HPA axis reactivity to socio-emotional stress (i.e., maternal unresponsiveness). VPT infants exhibited a blunted salivary cortisol reactivity, which was associated with the amount of skin-breaking procedures during NICU: greater pain-related stress predicted lower salivary cortisol reactivity, adjusting for neonatal confounders. These findings further advance our knowledge of how early exposure to pain-related stress in NICU contributes to the programming of an altered HPA axis reactivity to socio-emotional stress in 3-month-old VPT infants, even in the absence of major perinatal complications.

    The results of the clinical and pharmacoeconomic study of cerebrolysin in the rehabilitative therapy of ischemic stroke presented in the paper revealed the statistically significant regress of neurological disturbances in patients receiving cerebrolysin in daily dosages of 10 and 20 ml as compared to the control group. The rehabilitation of motor functions was more rapid than sensitive ones in patients receiving cerebrolysin comparing to those switched to the basic antihypertensive and antiaggregate therapy. The positive dynamics of speech rehabilitation was observed, the regress of aphatic disturbances being more significant for daily dosage of 20 ml. Rehabilitation rate in the period of treatment with cerebrolysin was higher for daily dosage of 20 ml than that of 10 ml. A prolonged effect of the drug during the long period after its withdrawal was found that resulted in higher rates of rehabilitation to the 11th week in patients receiving cerebrolysin as compared to the control group. Average total cost of direct medical expenses per a patient estimated in the pharmacoeconomic analysis for the groups receiving cerebrolysin and the control group was higher in the former groups, in particular in that with 20 ml dosage of cerebrolysin. A cost-efficacy analysis revealed that the cost of cerebrolysin treatment per effective unit (a cost of one score on the Lindmark scale and the Barthel scale) was less or comparable in patients receiving cerebrolysin comparing to the control group. The study suggests clinical and pharmacoeconomic expediency of cerebrolysin treatment in rehabilitative period of ischemic stroke.

    Neonatal rat pups (7 days old) were intubated with either 50 mg/kg body weight or 100 mg/kg body weight of aqueous root extract of Clitoria ternatea (CTR) for 30 days. These rats were then subjected to open field, two compartment passive avoidance and spatial learning (T-Maze) tests (i) immediately after the treatment and (ii) 30 days after the treatment, along with age matched normal and saline control rats. Results showed no change in open field behaviour, but showed improved retention and spatial learning performance at both time points of behavioural tests, indicating the memory enhancing property of CTR which implicates a permanent change in the brain of CTR treated rats.

    One compensatory mechanism for marginal zinc intake may be through an enhanced absorption of zinc. Such a compensatory mechanism could be of value to the neonate, as poor zinc nutriture during early life has severe consequences on growth and development. We studied the uptake of zinc by 3-month-old infant rhesus monkeys born to dams fed control diets 100 micrograms of zinc per gram of diet or zinc-restricted diets (4 micrograms of zinc per gram of diet). Zinc uptake/retention was studied by feeding 3-month-old infant monkeys that had fasted an infant formula containing zinc 65 by gavage. Whole body radioactivity was counted immediately after intubation and on days 10 and 17 after intubation. Regardless of dietary group, 65-zinc retention was high, ranging from 33% to 71% of the dose fed to the monkeys. There were no significant differences between the two dietary groups in the percentage of zinc retention at days 10 and 17. Independent of the dietary group, there was no correlation between plasma zinc and zinc absorption. A positive correlation was found between weight gain and zinc retention in the marginal zinc infants, while a negative correlation between weight gain and zinc retention was observed in the control infants. These observations suggest that the mechanisms underlying growth may be different in infants born to dams fed control vs marginal zinc diets.

    Neuromyelitis optica (NMO) is a severe inflammatory demyelinating disease of the central nervous system and preferentially targets the optic nerves and spinal cord. NMO is rare in children and clinical course of the disease is highly variable as described in studies. Here, we present a case report of a young girl presenting with a rare course of pediatric NMO with an early disease onset at the age of 12 years, a relapse free interval of 4 years, evidence of NMO immunoglobulin G (IgG) and an unusual response against immunosuppressive therapy. The aim of this report is to highlight the potentially long remission period between relapses complicating proper diagnosis despite well defined diagnostic criteria. In addition, we want to encourage the use of rituximab in pediatric NMO, although larger cohorts are warranted to establish B cell depleting therapies in juvenile NMO.

    Cryopyrin-associated periodic syndrome (CAPS) encompasses a spectrum of three phenotypes of increasing severity. The syndrome is due to dominant mutations in NLRP3, which encodes a key component of the innate immunity that regulates the secretion of IL-1β. CAPS manifests as systemic inflammation, which compromises quality of life and leads to serious complications and handicap. Anti-IL-1 drugs have shown remarkable efficacy in treating CAPS symptoms and have significantly changed patients' lives. They have acceptable safety profiles but do have some differences. We review three drugs that are currently marketed for CAPS, give additional information for the practical use of these drugs, and provide some recommendations for management. PMID:26312542

    Strawberries are available throughout the year either from production in the field or from high and low tunnel culture. Diversity of production conditions results in new challenges in controlling diseases before and after harvest. Fungicides have traditionally been used to control these diseases; however, their limitations necessitate a search for new approaches. We found that UV-C irradiation of Botrytis cinerea, a major pathogen of strawberry, can effectively kill this fungus if a dark period follows the treatment. The inclusion of a 4-h dark period resulted in almost complete kill of B. cinerea conidia on agar media at a dose of 12.36 J/m2. The UV-C dose did not cause a reduction in photosynthesis in strawberry leaves or discoloration of sepals, even after exposing plants repeatedly (twice a week) for 7 weeks. Although irradiation of dry conidia of B. cinerea with this dose resulted in some survival, the conidia were not infective and not able to cause decay even when inoculated onto a highly susceptible mature apple fruit. Irradiation of strawberry pollen at 12.36 J/m2 did not affect pollen germination, tube growth and length in vitro, or germination and tube growth in the style of hand-pollinated emasculated strawberry flowers. No negative effect of the UV-C treatment was observed on fruit yield and quality in high tunnel culture. In the fruit and flower petal inoculation tests, the UV-C treatment was highly effective in reducing fruit decay and petal infection. This UV-C treatment with an exposure time of 60 s may be useful in controlling gray mold in tunnel production of strawberries and may also have the potential for use in intensive field and indoor production of other fruits and vegetables providing that a 4-h dark period follows the irradiation.

    New-born calves depend upon colostrum intake for the acquisition of immunoglobulins (Ig) and other beneficial substances. However, colostrum is also a source of reactive oxygen species (ROS). Intrinsic production of ROS also increases after birth, so the combination of colostral and intrinsic ROS could overwhelm the antioxidant capacity of the calf leading to oxidative stress (OS), a condition that has been shown to play a key role in the initiation and development of several pathological conditions. The aim of this observational study was to assess the effects of the redox balance of colostrum on the oxidative status of calves and on passive immune transfer. Serum samples were taken from 20 calves on their day of birth, every week during their first month of life and at 2 and 3 months of age, and the concentrations of ROS and serum antioxidant capacity (SAC) assayed. The oxidative/anti-oxidative profile and IgG content of the colostrum were also assessed. The redox balance of the colostrum had a significant effect on both calf oxidative status and on passive immune transfer (as measured by calf serum IgG concentration), which indicates that the oxidative/antioxidative profile of colostrum should be measured when colostrum quality is assessed. The highest risk of OS during the study period was found to be when the calves were fed artificial milk replacer; this suggests that calves should be supplemented with antioxidants during this period in order to minimize any harmful consequences of high ROS generation.

    Exercise regimens suitable to the elderly remain under investigated; therefore, this study examined the effects of Dance Dance Revolution (DDR) on cognitive control in elderly females. Twenty-six healthy elderly females leading a sedentary lifestyle were assigned to a DDR, brisk walking, or control group. Participants in the DDR and brisk walking groups engaged in moderate physical exercise three times per week for 3 months, whereas the control group maintained a sedentary lifestyle. Each participant performed a flanker task before and after the intervention. The results revealed that both DDR and brisk walking shortened reaction time, N2 latency, and P3 latency relative to those of the control group. These findings suggest that DDR intervention is as effective as that of brisk walking in improving inhibitory control for elderly people. Therefore, DDR can be used as a viable alternative exercise to enhance cognitive function for the elderly and motivate individuals who are less willing to be active. PMID:25595954

    Aims To determine whether DTPP+Hib vaccination (diphtheria, tetanus, pertussis, poliomyelitis +/− haemophilus) increased the risk of sudden unexpected death (SUD) in children under 3 months of age. Methods We conducted a multicentre case-control study in the 28 French ‘SIDS Centers’. Case selection was based on death labelled sudden infant death syndrome (SIDS) of an infant aged between 30 and 90 days. Three living controls were selected, matched for sex, gestational age and born immediately after the victim in the same maternity unit. Results We identified 114 cases of SUD aged between 30 and 90 days and 341 live controls matched for age and sex and born in the same maternity unit as the case. DTPP±Hib immunization did not increase the risk of SUD (OR 1.08) (95% CI 0.49, 2.36) in children under 3 months of age when adjusted for sleeping position, illness in the week before death, maternal tobacco consumption, birth weight, type of mattress, breastfeeding and sex. However, low birth-weight (6.53 [2.29, 18.9]), multiple birth (5.1 [1.76, 15.13]), no breastfeeding (1.77 [1.1, 2.85]), prone sleeping position (9.8 [5, 8, 18, 9]), soft mattress (3.26 [1.69, 6.29]), recent illness (3.44 [1.84, 6.41]) and parental smoking (1.74 [1.2, 2.96]) were confirmed as risk factors in early SIDS. Conclusions DTPP±Hib immunization is not a risk factor for early SUD. In this population, we found the same risk factors as described for SIDS. PMID:11298074

    Percutaneous transluminal angioplasty has been successfully used for the treatment of transplant renal artery stenosis (RAS). Cutting-balloon angioplasty (CBA) is being used as a second option in pressure-resistant stenosis. It is thought that CBA is less traumatic and therefore restenosis occurs less frequently than in conventional angioplasty. This case report describes the unusual use of a cutting balloon in transplant RAS as a first option in the early postoperative period. Long-term follow-up data are also presented.

Dyscirculatory metabolic encephalopathy was revealed to be the main pathology with the etiological mechanism based on dyscirculatorhypoxic and metabolic disorders. Complexity of the revealed symptoms testified to an early organism aging in remote periods after exposure to low dose radiation. Pathogenetic schemes were developed for treatment of dyscirculatory encephalopathy in liquidators, which include drugs improving blood supply, antiaggregants, antioxidants and metabolites of the brains in various combinations. Taking into consideration that early appearance of vascular dyscirculatory disorders observed in liquidators is the sign of early aging of the organism, geroprotectors were added to treatment schemes.

    The authors tested the hypothesis that low-salt diet education by nutritionists would lower blood pressure (BP) levels in treated hypertensive patients. The amount of urinary salt excretion and clinic, home, and ambulatory BP values at baseline and at 3 months were measured in 95 patients with hypertension. After randomization to a nutritional education group (E group, n=51) or a control group (C group, n=44), the C group received conventional salt-restriction education and the E group received intensive nutritional education aimed at salt restriction to 6 g/d by nutritionists. From baseline to the end of the study, 24-hour urinary sodium excretion was significantly lowered in the E group compared with the C group (6.8±2.9 g/24 h vs 8.6±3.4 g/24 h, P<.01). Morning home systolic BP tended to be lowered in the E group (P=.051), and ambulatory 24-hour systolic BP was significantly lowered in the E group (-4.5±1.3 mm Hg) compared with the C group (2.8±1.3 mm Hg, P<.001). Intensive nutritional education by nutritionists was shown to be effective in lowering BP in treated hypertensive patients. PMID:26732187

    The changes triggered by sperm-induced activation of oocytes, which are required for normal oocyte development, can be mediated by other agents, thereby inducing the parthenogenesis. In this study, we exposed porcine oocytes to 1 mM Ca-EDTA, a metal-ion chelator, at various intervals during 48 hr of in vitro maturation to determine the optimum period of Ca-EDTA treatment for parthenogenetic activation. When the oocytes were cultured with or without Ca-EDTA from 36 hr (post-12), 24 hr (post-24), 12 hr (post-36) and 0 hr (post-48) after the start of maturation culture, the blastocyst formation rates were significantly higher (P<0.05) in the post-24, post-36 and post-48 groups (3.3%, 4.0% and 2.6%, respectively) than those in the control group without treatment (0%). Furthermore, when the oocytes were cultured with Ca-EDTA for 0 hr (control), 12 hr (pre-12), 24 hr (pre-24), 36 hr (pre-36) and 48 hr (pre-48) from the start of maturation culture, the oocytes formed blastocysts only in the pre-36 and pre-48 groups (0.4% or 0.8%, respectively). Pronuclei (<66.7%) were observed only when the periods of Ca-EDTA treatment were more than 12 hr during maturation culture. In the control group, no pronuclei were detected. Our findings demonstrate that porcine immature oocytes can be parthenogenetically activated by Ca-EDTA treatment for at least 24 hr to 36 hr during maturation culture, leading to pronucleus formation followed by the formation of blastocysts.

    Introduction The 1-, 3- and 6- month biodegradable polymer matrix depot formulations of leuprorelin acetate (Eligard®/Depo-Eligard®, Astellas Pharma Inc/BV) were shown to reduce testosterone and prostate-specific antigen levels and to be well tolerated in patients with advanced prostate cancer in several clinical trials. This study aimed at evaluating the efficacy, safety and tolerability of the 1- and 3-month leuprorelin acetate depot formulations in daily clinical practice. Material and methods A prospective, open-label, non-interventional, phase IV study (MANTA) was conducted in 243 Belgian prostate cancer patients who had been prescribed the 1-month (7.5 mg) or 3-month (22.5 mg) leuprorelin acetate depot formulation. Patients were followed for at least 3 months. Results Median serum prostate-specific antigen levels were reduced by 95% from 12.0 ng/ml at baseline to 0.60 ng/ml after a median follow-up time of 132 days, while median testosterone levels were reduced by 94% from 360 ng/dl to 20 ng/dl. Partial or complete treatment response was observed in 83% of patients at the final visit (according to the physician's assessment). Ninety-two patients (37.86%) experienced treatment-emergent adverse events, with injection site-related reactions, hot flushes and tumor flare being the most common ones. Overall safety and tolerability of the leuprorelin acetate depot formulation were rated as good or excellent by 90% of physicians. Conclusions These data are consistent with efficacy and tolerability results from clinical trials. They confirm that the 1- and 3-month leuprorelin acetate depot formulations are well tolerated and reliably lower serum prostate-specific antigen and testosterone levels in routine clinical practice.

    The aim of this study was to determine the timing of ovulation in relation to the LH peak after synchronization using PRID or Ovsynch protocols, to assess the effects of the period of treatment on these parameters and to provide information concerning how to use the two main protocols for fixed-time artificial insemination in buffalo. Forty-eight lactating Italian Mediterranean buffalo cows were used. The buffaloes were treated in various periods as follows: February to March (n = 12 PRID, n = 12 Ovsynch), end of the breeding season, May to June (n = 12 PRID, n = 12 Ovsynch), beginning of low-breeding season according to Italian environmental conditions. To determine the LH, blood samples were taken at 4-hour intervals, starting 24 hours from PRID removal (PRID group) or 12 hours from (PGF2α) injection (Ovsynch group) up to 108 hours. The ovaries were monitored by transrectal ultrasonography to verify ovulation. The LH-ovulation interval was similar in both groups (30.10 ± 1.05 and 32.77 ± 1.15 hours, respectively, in PRID and Ovsynch group). In the PRID group, the timing of ovulation in relation to device removal was 76.83 ± 3.65 hours with a high level of variability among the animals. In the Ovsynch group, we observed a better synchronization of LH peaks and ovulations, and the timing of ovulation in relation to the last GnRH injection was 35.67 ± 1.15 hours. The percentage of animals reaching the LH peak and ovulation was lower (P ≤ 0.05) in May to June (respectively 75.0% and 54.1%) compared to February to March (respectively 95.8% and 83.3%), indicating a reduction of hypothalamus-pituitary responsiveness to the synchronization treatments in the daylight-lengthening period.

    To relieve respiratory problems such as apnea in newborns, caffeine citrate is the drug of choice because of its good tolerance and therapeutic index. However, its impact on the intestinal microbial ecosystem and on bacterial translocation in the neonatal period remains insufficiently investigated. Therefore, the objective of this study was to evaluate the effects of caffeine citrate on the establishment of the intestinal microflora and bacterial translocation in rats from birth to the 30th day of life. Newborn Wistar rats were divided into four groups of 14 animals, each subdivided into a control group receiving a placebo (12mL tap water/kg/day) and another treated with caffeine citrate (12mg/kg/day). The animals were nursed by their mothers and weighed daily. A group of 14 rats was killed at birth and after 10, 20, or 30 days of life. Organs in which translocation was assessed (liver, lungs, spleen, and kidneys) and various fragments of intestine (duodenum, jejunum, ileum, and colon) were surgically removed. The bacteriological analysis performed involved enumeration of the total microflora, staphylococci, enterobacteria, and lactobacilli. From the 10th day, caffeine was shown to significantly decrease the weight of treated animals as compared with controls (P<0.05). However, caffeine treatment did not drastically alter the kinetics of establishment of the intestinal microflora as only enterobacteria were found to be significantly lower in any intestinal segment of the treated group (P<0.05). Moreover, from the 20th day of life, caffeine citrate significantly downregulated bacterial translocation of both Gram-positive and -negative bacteria (P<0.05). This preliminary study on the effects of treatment with caffeine citrate may open opportunities in clinical pediatrics; the treatment will remain partially effective in preventing bacterial translocation in the neonatal period.

    The overall objectives of the study were to develop a sensitive method for ethyl glucuronide (EtG) determination in hair and then investigate if a low or moderate intake of ethanol could be differentiated from total abstinence. Forty-four subjects were included in the study, 12 males (7 drinkers and 5 abstinent) and 32 females (14 drinkers and 18 abstinent). The study lasted 3 months and the female drinkers consumed one glass (16 g of ethanol) and the males consumed two glasses (32 g of ethanol) of wine (13.5-14%) daily. Hair samples were collected as close as possible above the skin and the proximal 2 cm were analyzed for EtG. Hair was cut into pieces of about 0.5 cm length and washed before incubation overnight in water and then extracted on Clean Screen EtG Carbon columns. The LC/MS/MS system consisted of a Waters ACQUITY UPLC connected to an API 4000 triple quadrupole instrument. Two transitions for EtG and one for the internal standard EtG-D(5) were measured. The method was linear from 60 to 10,000 pg/sample. Imprecision studies were performed at three levels as well as with an authentic sample. Total imprecision was 16% at 200 pg/sample, 8% at 1000 pg/sample, 6% at 8000 pg/sample and 13% at 29 pg/mg in the authentic sample. Of those who drank two glasses of wine every day, four had measurable amounts of EtG in their hair (5-11 pg/mg), and in only one of the females drinking one glass of wine EtG was quantified (3 pg/mg). Among the 23 abstinent subjects two had traces of EtG in the hair. We conclude that persons who ingested 16 or 32 g of ethanol daily for 3 months presented with low concentrations of EtG in hair, well below the proposed threshold for overconsumption set at 30 pg/mg. In addition, none of those who ingested 16 g/day had concentrations over the proposed abstinence threshold of 7 pg/mg. PMID:21367545

    Background: This double-blind, parallel-group, multicenter, phase-3 study was designed to test the noninferiority of paliperidone palmitate 3-month formulation (PP3M) to the currently marketed 1-month formulation (PP1M) in patients (age 18–70 years) with schizophrenia, previously stabilized on PP1M. Methods: After screening (≤3 weeks) and a 17-week, flexible-dosed, open-label phase (PP1M: day 1 [150mg eq. deltoid], day 8 [100mg eq. deltoid.], weeks 5, 9, and 13 [50, 75, 100, or 150mg eq., deltoid/gluteal]), clinically stable patients were randomized (1:1) to PP3M (fixed-dose, 175, 263, 350, or 525mg eq. deltoid/gluteal) or PP1M (fixed-dose, 50, 75, 100, or 150mg eq. deltoid/gluteal) for a 48-week double-blind phase. Results: Overall, 1016/1429 open-label patients entered the double-blind phase (PP3M: n=504; PP1M: n=512) and 842 completed it (including patients with relapse). PP3M was noninferior to PP1M: relapse rates were similar in both groups (PP3M: n=37, 8%; PP1M: n=45, 9%; difference in relapse-free rate: 1.2% [95% CI:-2.7%; 5.1%]) based on Kaplan-Meier estimates (primary efficacy). Secondary endpoint results (changes from double-blind baseline in positive and negative symptom score total and subscale scores, Clinical Global Impression-Severity, and Personal and Social Performance scores) were consistent with primary endpoint results. No clinically relevant differences were observed in pharmacokinetic exposures between PP3M and PP1M. Both groups had similar tolerability profiles; increased weight was the most common treatment-emergent adverse event (double-blind phase; 21% each). No new safety signals were detected. Conclusion: Taken together, PP3M with its 3-month dosing interval is a unique option for relapse prevention in schizophrenia. PMID:26902950

    In the decade since the first observationally based empirical studies of coparenting process in nuclear families made their mark, most investigations of early coparenting dynamics have examined whether and how such dynamics drive child development trajectories, rather than identifying factors that may contribute to the differential development of such dynamics in the first place. In this prospective study, we examined both individual-representational and dyadic-interpersonal predictors of early coparental process. Fifty married couples expecting their first child portrayed their expectations and concerns about family life after the baby's arrival, and took part in a set of problem-solving tasks used to help evaluate marital quality. Both mothers' and fathers' prebaby expectations about the future family, and prenatal marital quality, predicted observed coparenting cohesion at 3 months postpartum. Maternal- and marriage-coparenting trajectories differed as a function of infant characteristics, with pathways most pronounced when infants were rated high in negative reactivity. Results reveal how the prenatal environment can come to shape early coparenting process, and indicate that family models must take into account the role that child characteristics can play in altering prebirth-postpartum pathways.

    A 3-month-old infant was brought to clinic for evaluation of recurrent apparent life-threatening events (ALTEs). Two ALTE episodes occurred while the infant was sleeping in a safety car seat. The first one occurred when he was 4 weeks old. His mother noticed that he was not breathing; he appeared limp with full body cyanosis. His mother picked him up from the car seat, and he started breathing spontaneously and without any sign of distress. His skin color returned to normal. He was evaluated at the ED where the physical examination was normal. He was hospitalized 1 day for observation. During this time, workup, including ECG and chest radiograph, was normal. The parents were instructed on cardiorespiratory resuscitation and recommended to change car seats. The infant was discharged with an apnea monitor. He wore the apnea monitor while in the car seat. A second similar episode occurred at 10 weeks of age for which he was seen at the ED and referred to our clinic for further evaluation. Neither episode was related to feeding. PMID:25846540

    Objectives. We assessed the short-term ability to increase retail prices of the first US 1-cent-per-ounce excise tax on the distribution of sugar-sweetened beverages (SSBs), which was implemented in March 2015 by Berkeley, California. Methods. In 2014 and 2015, we examined pre- to posttax price changes of SSBs and non-SSBs in a variety of retailers in Berkeley and in the comparison cities Oakland and San Francisco, California. We examined price changes by beverage, brand, size, and retailer type. Results. For smaller beverages (≤ 33.8 oz), price increases (cents/oz) in Berkeley relative to those in comparison cities were 0.69 (95% confidence interval [CI] = 0.36, 1.03) for soda, 0.47 (95% CI = 0.08, 0.87) for fruit-flavored beverages, and 0.47 (95% CI = 0.25, 0.69) for SSBs overall. For 2-liter bottles and multipacks of soda, relative price increases were 0.46 (95% CI = 0.03, 0.89) and 0.49 (95% CI = 0.21, 0.77). We observed no relative price increases for nontaxed beverages overall. Conclusions. Approximately 3 months after the tax was implemented, SSB retail prices increased more in Berkeley than in nearby cities, marking a step in the causal pathway between the tax and reduced SSB consumption.

    The rapid growth of observed exoplanets has revealed the existence of several distinct planetary populations in the mass-period diagram. Two of the most surprising are (1) the concentration of gas giants around 1 AU and (2) the accumulation of a large number of low-mass planets with tight orbits, also known as super-Earths and hot Neptunes. We have recently shown that protoplanetary disks have multiple planet traps that are characterized by orbital radii in the disks and halt rapid type I planetary migration. By coupling planet traps with the standard core accretion scenario, we showed that one can account for the positions of planets in the mass-period diagram. In this paper, we demonstrate quantitatively that most gas giants formed at planet traps tend to end up around 1 AU, with most of these being contributed by dead zones and ice lines. We also show that a large fraction of super-Earths and hot Neptunes are formed as 'failed' cores of gas giants—this population being constituted by comparable contributions from dead zone and heat transition traps. Our results are based on the evolution of forming planets in an ensemble of disks where we vary only the lifetimes of disks and their mass accretion rates onto the host star. We show that a statistical treatment of the evolution of a large population of planetary cores caught in planet traps accounts for the existence of three distinct exoplanetary populations—the hot Jupiters, the more massive planets around r = 1 AU, and the short-period super-Earths and hot Neptunes. There are very few populations that feed into the large orbital radii characteristic of the imaged Jovian planet, which agrees with recent surveys. Finally, we find that low-mass planets in tight orbits become the dominant planetary population for low-mass stars (M {sub *} ≤ 0.7 M {sub ☉}).

  13. Fall in incidence of guinea-worm infection in western Nigeria after periodic treatment of infected persons.

    Between 1971 and 1974 a series of drug trials was conducted in 17 rural communities in western Nigeria where guinea-worm is endemic. During these trials and in subsequent years treatment, in the form of chemotherapy and/or dressing of ulcers, was given to all infected persons. A longitudinal study of infection in these villages showed a marked fall in the annual incidence over an 8-year period. The aggregate reduction in incidence in the three sectors surveyed was from 15.5% to 0.5% in sector 1, 29.8% to 0.4% in sector 2, and 20.3% to 0.0% in sector 3. The change appeared to be partly due to the treatment, which reduced the reservoir of infection and the rate of pollution of the water supply. Most of the sources of water continued to harbour Cyclops, none of which was found to be infected with Dracunculus, but which were shown experimentally to be capable of sustaining infection. The study demonstrates the potential role of therapeutic measures in controlling guinea-worm infection. It is suggested that the satisfactory measure of control that has been achieved could be increased by elimination of the Cyclops, with a view to total eradication of the disease from affected communities. Attention is drawn to the relevance of the findings for the International Drinking Water Supply and Sanitation Decade.

    Maternal depression and anxiety represent risk factors for the quality of early mother-preterm infant interactions, especially in the case of preterm birth. Despite the presence of many studies on this topic, the comorbidity of depressive and anxious symptoms has not been sufficiently investigated, as well as their relationship with the severity of prematurity and the quality of early interactions. The Aim of this study was to evaluate the quality of early mother-infant interactions and the prevalence of maternal depression and anxiety comparing dyads of extremely low birth weight (ELBW) and very low birth weight (VLBW) preterm infants with full-term ones. Seventy seven preterm infants (32 ELBW; 45 VLBW) and 120 full term (FT) infants and their mothers were recruited. At 3 months of corrected age, 5 min of mother-infant interactions were recorded and later coded through the Global Ratings Scales. Mothers completed the Edinburgh Postnatal Depression Scale and Penn State Worry Questionnaire. Infant levels of development were assessed through the Griffiths Mental Development Scales. A relation emerged among the severity of prematurity, depression, anxiety, and the quality of interactions. When compared with the FT group, the ELBW interactions were characterized by high maternal intrusiveness and low remoteness, while the VLBW dyads showed high levels of maternal sensitivity and infant communication. Depression was related to maternal remoteness and negative affective state, anxiety to low sensitivity, while infant interactive behaviors were impaired only in case of comorbidity. ELBW’s mothers showed the highest prevalence of depressive and anxious symptoms; moreover, only in FT dyads, low maternal sensitivity, negative affective state and minor infant communication were associated to the presence of anxious symptoms. The results confirmed the impact of prematurity on mother–infant interactions and on maternal affective state. Early diagnosis can help to plan

  15. How a hat may affect 3-month-olds' recognition of a face: an eye-tracking study.

    Recent studies have shown that infants' face recognition rests on a robust face representation that is resilient to a variety of facial transformations such as rotations in depth, motion, occlusion or deprivation of inner/outer features. Here, we investigated whether 3-month-old infants' ability to represent the invariant aspects of a face is affected by the presence of an external add-on element, i.e. a hat. Using a visual habituation task, three experiments were carried out in which face recognition was investigated by manipulating the presence/absence of a hat during face encoding (i.e. habituation phase) and face recognition (i.e. test phase). An eye-tracker system was used to record the time infants spent looking at face-relevant information compared to the hat. The results showed that infants' face recognition was not affected by the presence of the external element when the type of the hat did not vary between the habituation and test phases, and when both the novel and the familiar face wore the same hat during the test phase (Experiment 1). Infants' ability to recognize the invariant aspects of a face was preserved also when the hat was absent in the habituation phase and the same hat was shown only during the test phase (Experiment 2). Conversely, when the novel face identity competed with a novel hat, the hat triggered the infants' attention, interfering with the recognition process and preventing the infants' preference for the novel face during the test phase (Experiment 3). Findings from the current study shed light on how faces and objects are processed when they are simultaneously presented in the same visual scene, contributing to an understanding of how infants respond to the multiple and composite information available in their surrounding environment.

    We performed topography and raytracing analysis 3 months after surgery on five consecutive eyes of five patients, which had excimer laser photorefractive keratectomy for myopia. Three of the five eyes had uncorrected postoperative visual acuity of 20/20 or better. Two eyes had an uncorrected vision of 20/40. In three of five eyes, the area of excimer ablation was centered within 1.0 mm of the optical axis. Three other eyes showed decentration that ranged from 1.1 to 1.5 mm. The range of surface power seen within 2 mm of the central keratoscope ring was as follows: patient CK = 37.50 to 39.50 diopters; patient CA = 40.50 D to 44.80 D; patient CW = 37.90 D to 42.20 D; patient AC = 35.50 D to 39.00 D; patient DT = 34.50 D to 41.40 D. Topography patterns differed from eye to eye. A raytracing program modeled refraction of 20/80 and 20/20 "E" of 100%, 50%, 25%, 12.5% and 6.25% contrast through all measured points on the central 10 keratoscope rings of the five postoperative corneas. The five computer-derived images were ranked subjectively according to the observed degree of image degradation by three observers. Two eyes showed discernible 20/20 E's even at the 12.5% contrast level. Little to no ghost image was seen. Two eyes showed degraded but discernible 20/20 letters at higher levels of contrast only. These eyes showed moderate ghost images that were most apparent in the high-contrast 20/80 letters. One eye showed poor resolution of the 100% contrast 20/20 letter and moderately severe ghost images.(ABSTRACT TRUNCATED AT 250 WORDS) PMID:2043557

    1993-05-15

    We propose a conditional analysis for outcome data on numbers of recurrent symptoms arising in a two-treatment, multiple-period crossover trial. Conditioning on subject-specific totals removes any dependence on mean subject-specific symptom rates and permits the use of standard software to perform regression analysis to examine treatment, period, carryover and interaction effects. The addition of offsets to the regression equations allows the incorporation of data from subjects who do not complete all periods in the trial. We apply the proposed method to data from a crossover trial and discuss its advantages and disadvantages.

    There are various anticholinesterase inhibitors (AChEIs) for the symptomatic treatment of mild to moderate Alzheimer's disease (AD). All AChEIs have shown greater efficacy than placebo in randomized, double-blind, parallel-group clinical trials. No differential studies have yet been made of the efficacy between all AChEIs. The study aims to determine the differential efficacy of the AChEIs with respect to a historical sample of patients with AD that were not treated with AChEIs. An open-label, prospective, observational study with a retrospective control group was undertaken to examine the evolution of the cognitive function over a 6-month period. The patients were assessed with the Mini-Mental State Examination (MMSE) at study entry and at 6 months. A general linear model was applied for repeated measurements with the MMSE score as the dependent variable, treatment type as an independent variable and the severity of the deterioration, age and the MMSE baseline score as covariables. Of the sample of 147 patients, 40 initiated treatment with donepezil, 32 with galantamine, 30 with rivastigmine and 45 were part of a historical sample of the memory clinic patients between 1991 and 1996 that had not been treated with AChEIs. The average age was 73.7 years (SD = 6.9; range = 52-86), 67.3% were women, 78.2% of the cases were mild and the MMSE baseline score was 18.1 points (range = 11-27). No significant intergroup differences were observed in these variables. The average doses of donepezil, galantamine and rivastigmine were 5.87 mg/day (SD = 1.92), 14.81 mg/day (SD = 6.25) and 6.41 mg/day (SD = 1.82), respectively. At 6 months, the difference in the MMSE score with respect to the untreated group was 1.6 points for donepezil (95% CI 0.79-2.37; p < 0.001), 0.99 points for galantamine (95% CI 0.14-1.85; p = 0.01) and 0.90 points for rivastigmine (95% CI 0.05-1.74; p = 0.03).

    The management of recurrent furunculosis is difficult, and often disappointing. We present the case of a 23-year-old female patient suffering from recurrent furunculosis. The furunculosis persisted after treatment with mupirocin nasal ointment, chlorhexidine soap and instructions for washing clothes, towels and bed sheets for a period of 7 days. Treatment with low-dose clindamycin for three months ultimately proved successful. We propose a structural approach for recurrent furunculosis in which extensive history-taking is followed by appropriate tests. Before prescribing an oral antibiotic (preferably low-dose clindamycin or a macrolide for 3 months), the patient should use an antimicrobial nasal ointment and soap and follow hygienic instructions as mentioned above. Members of the household who also have signs of the infection should be treated. Hygienic education is an essential component of treatment. We believe that this approach will lead to a treatment that is more effective and efficient.

    Ca supplements are used for bone health; however, they have been associated with increased cardiovascular risk, which may relate to their acute effects on serum Ca concentrations. Microcrystalline hydroxyapatite (MCH) could affect serum Ca concentrations less than conventional Ca supplements, but its effects on bone turnover are unclear. In the present study, we compared the acute and 3-month effects of MCH with conventional Ca supplements on concentrations of serum Ca, phosphate, parathyroid hormone and bone turnover markers. We randomised 100 women (mean age 71 years) to 1 g/d of Ca as citrate or carbonate (citrate-carbonate), one of two MCH preparations, or a placebo. Blood was sampled for 8 h after the first dose, and after 3 months of daily supplementation. To determine whether the acute effects changed over time, eight participants assigned to the citrate dose repeated 8 h of blood sampling at 3 months. There were no differences between the citrate and carbonate groups, or between the two MCH groups, so their results were pooled. The citrate-carbonate dose increased ionised and total Ca concentrations for up to 8 h, and this was not diminished after 3 months. MCH increased ionised Ca concentrations less than the citrate-carbonate dose; however, it raised the concentrations of phosphate and the Ca-phosphate product. The citrate-carbonate and MCH doses produced comparable decreases in bone resorption (measured as serum C-telopeptide (CTX)) over 8 h and bone turnover (CTX and procollagen type-I N-terminal propeptide) at 3 months. These findings suggest that Ca preparations, in general, produce repeated sustained increases in serum Ca concentrations after ingestion of each dose and that Ca supplements with smaller effects on serum Ca concentrations may have equivalent efficacy in suppressing bone turnover.

    Background: The role of cytokines as a marker in the oral inflammatory process in ECC has not been fully explored before and after full mouth rehabilitation. Aims: The aim of this study was to assess the level of salivary interleukin-6 (IL-6) in children with ECC and to compare its levels before and after comprehensive full mouth rehabilitation. Methods and Materials: Saliva samples were collected from children with ECC prior to dental treatment and 3-month post treatment. The salivary IL-6 levels were analyzed using the ELISA method. The gingival index was also timely recorded. Oral health awareness sessions were conducted for children and their parents at regular intervals during the 3-month study period. Statistical analysis used: Wilcoxon Signed Rank test compared the levels of salivary IL-6 while, the paired t test compared the values of gingival index before and after treatment. Results: The mean level of salivary IL-6 before and 3 months after treatment had reduced and this reduction was statistically significant (P < 0.000). The gingival index scores had also reduced significantly 3-months post treatment (P < 0.002). Conclusions: Children with ECC when completely rehabilitated and kept under frequent follow up, which includes reinforcement of oral hygiene measures and maintaining a low caries activity state, the level of inflammation (IL-6) can definitely be minimized and thereby improving the quality of life of affected children.

    The efficacy of magnetic-laser therapy used according to the method developed by us was studied in patients having the brain concussion (BC) in an acute period. The study was based on the dynamics of values of the evoked vestibular potentials and the disease clinical course. It was shown that following the magnetic-laser therapy in combination with traditional pharmacotherapy in BC acute period, the statistically significant positive changes were registered in the quantitative characteristics of the evoked vestibular brain potentials that correlated with the dynamics of the disease clinical course. The data obtained substantiate the possibility of using the magnetic-laser therapy in patients with a mild craniocereblal injury in an acute period.

    Maternal depression is highly prevalent (10 to 20%) during the perinatal period with rates as high as 35 to 40% for Latinas. However, few Latinas are either identified or treated during the perinatal period. To address these disparities, the Perinatal Mental Health Model (PMH) was designed to ameliorate the barriers that prevent adequate diagnoses and intervention. The PMH is a culturally sensitive, short-term telemedicine, and collaborative care intervention for addressing depression among Mexican American mothers. It attends to sociocultural and socioeconomic dimensions and is delivered by trained mental health advisors within obstetric care settings. This article describes the feasibility and acceptability of utilizing the PMH. Participants (n=79) were selected from a first year ongoing randomized trial in community obstetric clinics. The intervention seems feasible and acceptable; low-income Latinas, identified as depressed during the perinatal period, reported having access to a range of appropriate community services and high satisfaction.

    This paper describes an individual who was diagnosed with obsessive-compulsive disorder (OCD) and body dysmorphic disorder (BDD) at age 17 when education was discontinued. By age 19, he was housebound without social contacts except for parents. Adequate trials of three selective serotonin reuptake inhibitors, two with atypical neuroleptics, were ineffective. Major exacerbations following ear infections involving Group A β-hemolytic streptococcus at ages 19 and 20 led to intravenous immune globulin therapy, which was also ineffective. At age 22, another severe exacerbation followed antibiotic treatment for H. pylori. This led to a hypothesis that postulates deficient signal transduction by the N-methyl-D-aspartate receptor (NMDAR). Treatment with glycine, an NMDAR coagonist, over 5 years led to robust reduction of OCD/BDD signs and symptoms except for partial relapses during treatment cessation. Education and social life were resumed and evidence suggests improved cognition. Our findings motivate further study of glycine treatment of OCD and BDD. PMID:20182547

    Patient ratings of satisfaction with their postoperative pain treatment tend to be high even in those with substantial pain. Determinants are poorly understood and have not previously been studied in large-scale, international datasets. PAIN OUT, a European Union-funded acute pain registry and research project, collects patient-reported outcome data on postoperative day 1 using the self-reported International Pain Outcome Questionnaire (IPO), and patient, clinical, and treatment characteristics. We investigated correlates of satisfaction and consistency of effects across centres and countries using multilevel regression modelling. Our sample comprised 16,868 patients (median age 55 years; 55% female) from 42 centres in 11 European countries plus Israel, USA, and Malaysia, who underwent a wide range of surgical procedures, for example, joint, limb, and digestive tract surgeries. Median satisfaction was 9 (interquartile range 7-10) on a 0-10 scale. Three IPO items showed strong associations and explained 35% of the variability present in the satisfaction variable: more pain relief received, higher allowed participation in pain treatment decisions, and no desire to have received more pain treatment. Patient factors and additional IPO items reflecting pain experience (eg, worst pain intensity), pain-related impairment, and information on pain treatment added little explanatory value, partially due to covariate correlations. Effects were highly consistent across centres and countries. We conclude that satisfaction with postoperative pain treatment is associated with the patients' actual pain experience, but more strongly with impressions of improvement and appropriateness of care. To the degree they desire, patients should be provided with information and involved in pain treatment decisions. PMID:24785269

    OBJECT There is a paradigm shift toward rewarding providers for quality rather than volume. Complications appear to occur at a fairly consistent frequency in large aggregate data sets. Understanding how complications affect long-term patient-reported outcomes (PROs) following degenerative lumbar surgery is vital. The authors hypothesized that 90-day complications would adversely affect long-term PROs. METHODS Nine hundred six consecutive patients undergoing elective surgery for degenerative lumbar disease over a period of 4 years were enrolled into a prospective longitudinal registry. The following PROs were recorded at baseline and 12-month follow-up: Oswestry Disability Index (ODI) score, numeric rating scales for back and leg pain, quality of life (EQ-5D scores), general physical and mental health (SF-12 Physical Component Summary [PCS] and Mental Component Summary [MCS] scores) and responses to the North American Spine Society (NASS) satisfaction questionnaire. Previously published minimum clinically important difference (MCID) threshold were used to define meaningful improvement. Complications were divided into major (surgicalsite infection, hardware failure, new neurological deficit, pulmonary embolism, hematoma and myocardial infarction) and minor (urinary tract infection, pneumonia, and deep venous thrombosis). RESULTS Complications developed within 90 days of surgery in 13% (118) of the patients (major in 12% [108] and minor in 8% [68]). The mean improvement in ODI scores, EQ-5D scores, SF-12 PCS scores, and satisfaction at 3 months after surgery was significantly less in the patients with complications than in those who did not have major complications (ODI: 13.5 ± 21.2 vs 21.7 ± 19, < 0.0001; EQ-5D: 0.17 ± 0.25 vs 0.23 ± 0.23, p = 0.04; SF-12 PCS: 8.6 ± 13.3 vs 13.0 ± 11.9, 0.001; and satisfaction: 76% vs 90%, p = 0.002). At 12 months after surgery, the patients with major complications had higher ODI scores than those without complications (29.1

    Model for end-stage liver disease (MELD) scoring was initiated using traditional statistical technique by assuming a linear relationship between clinical features, but most phenomena in a clinical situation are not linearly related. The aim of this study was to predict 3-month mortality risk of acute-on-chronic hepatitis B liver failure (ACHBLF) on an individual patient level using an artificial neural network (ANN) system. The ANN model was built using data from 402 consecutive patients with ACHBLF. It was trained to predict 3-month mortality by the data of 280 patients and validated by the remaining 122 patients. The area under the curve of receiver operating characteristic (AUROC) was calculated for ANN and MELD-based scoring systems. The following variables age (P < 0.001), prothrombin activity (P < 0.001), serum sodium (P < 0.001), total bilirubin (P = 0.015), hepatitis B e antigen positivity rate (P < 0.001) and haemoglobin (P < 0.001) were significantly related to the prognosis of ACHBLF and were selected to build the ANN. The ANN performed significantly better than MELD-based scoring systems both in the training cohort (AUROC = 0.869 vs 0.667, 0.591, 0.643, 0.571 and 0.577; P < 0.001, respectively) and in the validation cohort (AUROC = 0.765 vs 0.599, 0.563, 0.601, 0.521 and 0.540; P ≤ 0.006, respectively). Thus, the ANN model was shown to be more accurate in predicting 3-month mortality of ACHBLF than MELD-based scoring systems. PMID:23490369

    The association between suboptimal infant feeding practices and growth faltering is well-established. However, most of this evidence comes from cross-sectional studies. To prospectively assess the association between suboptimal infant feeding practices and growth faltering, we interviewed pregnant women at 28–32 weeks’ gestation and followed-up their offspring at postnatal months 3, 9, 16 and 24 months in rural Bangladesh. Using maternal recall over the past 24 hours, exclusive breastfeeding (EBF) status at 3 months, age at complementary feeding (CF) initiation, and receipt of minimum acceptable diet (MAD; as defined by WHO) at 9 months were assessed. Infant length and weight measurements were used to produce length-for-age (LAZ) and weight-for-length (WLZ) z-scores at each follow-up. Generalized estimating equations were used to estimate associations of LAZ and WLZ with infant feeding practices. All models were adjusted for baseline SES, infant sex, maternal height, age, literacy and parity. Follow-up was completed by 2189, 2074, 1969 and 1885 mother-child dyads at 3, 9, 16 and 24 months, respectively. Stunting prevalence increased from 28% to 57% between infant age 3 and 24 months. EBF at 3 months and age at CF initiation were not associated with linear infant growth, but receipt of MAD at 9 months was. By age 24 months, infants receiving MAD had attained a higher LAZ compared to infants who did not receive MAD (adjusted β = 0.25, 95% CI: 0.13–0.37). Although prevalence of stunting was already high at age 3 months, ensuring infants receive a diverse, high quality diet from 6 months onwards may reduce rates of stunting in the second year of life.

    Summary This study evaluated body composition outcomes following a 3-month exercise program for overweight/obese Black women. BMI decreased over the 3-month study despite an observed increase in body fat. Enhancements in bone marrow density and muscle density were also observed. Results show promising yet hypothesis-generating findings to explore in future research. Introduction Few studies have evaluated the relationship between aerobic physical activity (PA) and body composition among young adult overweight/obese African American (AA) women. Purpose The current study evaluated the effect of a 3-month moderate-intensity aerobic physical activity intervention for overweight and obese young adult women on bone, lean, and fat mass. Methods Participants (n=15) were a randomly selected subset of AA female college students (M age=21.7 years; M BMI= 33.3) enrolled in a larger PA promotion pilot study (n=31). Study protocol required participants to engage in four 30–60-min moderate-intensity aerobic PA sessions each week. Whole body composition was measured by dual-energy X-ray absorptiometry (DXA), and peripheral quantitative computed tomography (pQCT) was used to assess additional quantitative and qualitative assessment of the radius. Results BMI decreased over the duration of the study (P=.034), reflected by a marginal decrease in body weight (P=.057). However, unexpectedly, increases in adipose tissue measures were observed, including total body fat (P=.041), percent body fat (P=.044), trunk fat (P=.031), and percent trunk fat (P=.041). No changes in DXA-measured bone outcomes were observed (i.e., bone mineral density, P=.069; bone mineral content, P=.211). Results from the pQCT assessment showed that bone marrow density increased (P=.011), but cortical density remained stable (P=.211). A marginally significant increase in muscle density (P=.053) and no changes in muscle area (P=.776) were observed. Conclusions A 3-month moderate-intensity PA program was associated

    Background Very little is known about the range of diagnoses, course of treatment and long-term outcome in elderly patients who choose to receive homeopathic medical treatment. We investigated homeopathic practice in an industrialised country under everyday conditions. The aim of the study was to determine the spectrum of diagnoses and treatments, as well as to describe the course of illness over time among older patients who chose to receive homeopathic treatment. Methods In this subgroup analysis of a prospective, multicentre cohort study totally including 3981 patients treated by homeopathic physicians in primary care practices in Germany and Switzerland, data was analysed from all patients > 70 years consulting the physician for the first time. The main outcome measures were: assessment by patient of the severity of complaints (numeric rating scales) and quality of life (SF-36) and by the physician of the severity of diagnoses (numeric rating scales) at baseline, and after 3, 12, and 24 months. Results A total of 83 patients were included in the subgroup analysis (41% men, mean age 73.2 ± (SD) 3.1 years; 59% women, 74.3 ± 3.8 years). 98.6 percent of all diagnoses were chronic with an average duration of 11.5 ± 11.5 years. 82 percent of the patients were taking medication at baseline. The most frequent diagnoses were hypertension (20.5%, 11.1 ± 7.5 years) and sleep disturbances (15.7%, 22.1 ± 25.8 years). The severity of complaints decreased significantly between baseline and 24 months in both patients (from 6.3 (95%CI: 5.7-6.8) to 4.6 (4.0-5.1), p < 0.001) and physicians' assessments (from 6.6 (6.0-7.1) to 3.7 (3.2-4.3), p < 0.001); quality of life (SF 36) and the number of medicines taken did not significantly change. Conclusion The severity of disease showed marked and sustained improvements under homeopathic treatment, but this did not lead to an improvement of quality of life. Our findings might indicate that homeopathic medical therapy may play a

    Pressure sores are frequently seen in elderly hospitalized patients and leads to prolonged hospitalization and increased morbidity and mortality. The object of this paper was to retrieve the last five years literature regarding prevention and treatment of pressure sores. During the period 1987-1991, 751 papers on this topic were published and indexed in Medline. Only 9 of these papers represented controlled clinical trials. Three of them dealt with prevention, and the remaining 6 with treatment. Although 4 of 9 studies showed statistically significant differences between the actively treated group and the placebo group, none of the studies showed convincing clinical differences. Serious methodological flaws with respect to design, blinding, randomisation, sample size and statistical analysis were found in 8 of 9 studies. None of the clinical controlled studies on prevention of pressure sores showed any statistically significant differences between the control group and treatment with, respectively Prevasore lotion, Foam cushion and Silicore mattress. In the 6 trials on treatment of pressure sores, respectively mucopolysaccharide polysulphate creme, ketanserin creme and air-fluidized beds showed statistically better results than control treatment. We conclude that well-designed controlled clinical trials are needed to establish rational routines for prevention and treatment of pressure sores.

    Background: Cannabis continues to be the most commonly used illicit psychoactive substance globally. The National Survey in India conducted in the year 2004 also reported it to be the most commonly used illicit substance in the country. Furthermore, it was reported to be the second most commonly used psychoactive substance by the treatment seekers at de-addiction centers in the country. Objectives: To assess time trends of cannabis use among treatment-seeking individuals at government de-addiction centers across India over a period of 7 years. Materials and Methods: The study utilized data collected through Drug Abuse Monitoring System across India. The data of treatment seekers from de-addiction centers established under the Drug De-addiction Program, Ministry of Health and Family Welfare, Government of India and supported by the Ministry of Social Justice and Empowerment, Government of India (122 in number) across the country were analyzed. Results: A total of 107,469 individuals sought treatment from government de-addiction centers over the 7 years (2007–2013) period. With the exception of an aberration for the year 2012, there has been a steady decline in the proportion of treatment seekers who are not current cannabis users. A significantly greater proportion (Chi-square: 586.30, df: 1, P < 0.001) of individuals with current cannabis use alone or along with tobacco (20.4%) tend to have a co-morbid psychiatric disorder as compared to treatment seekers with current use of substances other than cannabis (6.1%). Conclusions: It is important to focus on cannabis in clinical service delivery and research in the country. PMID:27570345

    The complete timeline for maturation of human cochlear function has not been defined. Distortion product otoacoustic emission (DPOAE)-based measures of cochlear function show non-adult-like responses from premature and term-born neonates at high f2 frequencies; however, older infants were not included in these studies. In the present experiment, previously collected DPOAE ipsilateral suppression data from premature neonates were combined with new data collected from adults, term-born neonates, and 3-month-old infants to further examine the time course for maturation of cochlear function. DPOAE suppression tuning curves (STC) and suppression growth patterns were measured in the three age groups at f2=6000 Hz, L1=65, L2=55 dB SPL, with an f2/f1 of 1.2. Results indicate that term-born neonates and 3-month-old infants have non-adult-like STC width, slope on the low-frequency flank, and tip features. However, the two infant groups are not significantly different from one another. Suppression growth patterns for low-frequency suppressor tones show a clear developmental progression. In general, the younger the infant, the more shallow and compressive the suppression growth for the lowest suppressor frequencies. These findings suggest a high-frequency postnatal immaturity in cochlear function as measured by DPOAE suppression. Results may have been influenced by noncochlear factors, such as middle-ear immaturity. These factors are reviewed and considered. .

    Patients after allogeneic hematopoietic SCT (HSCT) are at risk of malnutrition. To assess the impact of malnutrition after allogeneic HSCT on transplant outcomes, we conducted a retrospective study. Adult patients who received allogeneic HSCT from 2000 to 2009 for standard-risk leukemia and achieved disease-free survival up to 3 months after allogeneic HSCT were included. From participating centers, 145 patients were enrolled. Median age was 46 years (19-68). Patients were classified based on weight loss during 3 months after allogeneic HSCT as follows: normal group (weight loss <5%, n=53), mild malnutrition group (5%⩽weight loss<10%, n=47), severe malnutrition group (10% ⩽weight loss, n=45). The cumulative incidences of 2-year nonrelapse mortality (NRM) were 3.8% in the normal group, 8.5% in the mild malnutrition group and 27.3% in the severe malnutrition group. The probabilities of a 2-year OS were 73.2% in the normal group, 74.5% in the mild malnutrition group and 55.3% in the severe malnutrition group. In multivariate analysis, severe malnutrition was associated with an increased risk of NRM and a worse OS. In conclusion, weight loss ⩾10% was associated with a worse clinical outcome. Prospective studies that identify patients at risk of malnutrition and intervention by a nutritional support team are warranted. PMID:25285803

    Circadian rhythms in cardiac function are apparent in e.g., blood pressure, heart rate, and acute adverse cardiac events. A circadian clock in heart tissue has been identified, but entrainment pathways of this clock are still unclear. We cultured tissues of mice carrying bioluminescence reporters of the core clock genes, period 1 or 2 (per1luc or PER2LUC) and compared in vitro responses of atrium to treatment with medium and a synthetic glucocorticoid (dexamethasone [DEX]) to that of the suprachiasmatic nucleus (SCN) and liver. We observed that PER2LUC, but not per1luc is rhythmic in atrial tissue, while both per1luc and PER2LUC exhibit rhythmicity in other cultured tissues. In contrast to the SCN and liver, both per1luc and PER2LUC bioluminescence amplitudes were increased in response to DEX treatment, and the PER2LUC amplitude response was dependent on the time of treatment. Large phase-shift responses to both medium and DEX treatments were observed in the atrium, and phase responses to medium treatment were not attributed to serum content but the treatment procedure itself. The phase-response curves of atrium to both DEX and medium treatments were found to be different to the liver. Moreover, the time of day of the culturing procedure itself influenced the phase of the circadian clock in each of the cultured tissues, but the magnitude of this response was uniquely large in atrial tissue. The current data describe novel entrainment signals for the atrial circadian clock and specifically highlight entrainment by mechanical treatment, an intriguing observation considering the mechanical nature of cardiac tissue.

    The present study illustrates the influence of microaerophilic condition on periodic discontinuous batch reactor (PDBR) operation in treating azo dye containing wastewater. The process performance was evaluated with the function of various dye load operations (50-750 mg/l) by keeping the organic load (1.6 kg COD/m(3)-day) constant. Initially, lower dye operation (50mg dye/l) resulted in higher dye [45 mg dye/l (90%)] and COD [SDR: 1.29 kg COD/m(3)-day (92%)] removal efficiencies. Higher dye load operation (750 mg dye/l) also showed non-inhibitory performance with respect to dye [600 mg dye/l (80%)] and COD [1.25 kg COD/m(3)-day (80%)] removal efficiencies. Increment in dye load showed increment in azo reductase and dehydrogenase activities (39.6 U; 4.96 μg/ml; 750 mg/l). UV-Vis spectroscopy (200-800 nm), FTIR and (1)H NMR studies revealed the disappearance of azo bond (-NN-). First derivative cyclic voltammogram supported the involvement of various membrane bound redox shuttlers, viz., cytochrome-C, cytochrome-bc1 and flavoproteins (FAD (H)).

    Introduction: This review sought to investigate the safety of intravesical administration of Mycobacterium phlei cell wall-nucleic acid (MCNA) in the immediate postoperative period after biopsy/resection for non-muscle-invasive bladder cancer (NMIBC). Methods: Patients with NMIBC who failed bacillus Calmette-Guérin (BCG) therapy and at high risk of recurrence and progression participated in this study. Treatment involved an induction phase of six weeks and maintenance of three weekly instillations every six months for two years. Biopsies were mandatory at six months and resections/biopsies as indicated. Of the 129 patients enrolled, 18 (14%) received one or more instillations of MCNA within 24 hours of an endoscopic procedure for a total of 32 instillations. Results: Fourteen patients (78%) received MCNA in the immediate postoperative period. Two (11%) received treatment the day after surgery, but a second treatment immediately after a transurethral resection of the bladder tumour (TURBT). The remaining two patients received an instillation each the day after surgery. Adverse events (AEs) occurred in 31.3% of those treated immediately after the procedure; they were mild, limited to the lower urinary tract, and not drug-related. Only one patient experienced systemic symptoms of moderate severity. None of the AEs resulted in postponement of treatment. There were no AEs among those receiving MCNA the day after surgery. Conclusions: The dual mechanism of action of MCNA suggests that early treatment would take advantage of its chemotherapeutic (pro-apoptotic) activity. Concerns about early administration due to the presence of live bacteria are circumvented with this sterile preparation. These preliminary results warrant further investigation to confirm the safety of perioperative administration of MCNA. PMID:27800054

    Variation in anoxic microenvironment (multi-phase (MP) metabolic shift strategy) during cycle operation of periodic discontinuous batch/sequencing batch (PDBR/SBR) mode operation showed enhanced degradation of recalcitrant azo dye (C.I. Acid Black 10B) at higher dye load (1250mg/l). The process performance was evaluated by varying anoxic phasing period during cycle operation. Before multiphase (BMP) operation with 2.1% of anoxic period showed color/COD removal efficiency of 41.9%/46.3%. Increment in anoxic period responded favorable in enhancing treatment efficiency [AMPI (16.2%), 49.4%/52.4%; AMPII (26.6%), 54.7%/57.2%; AMPIII (34.9%), 58.4%/61.5%]. Relatively higher bio-electrochemical activity, persistent reductive behavior (redox catalytic currents, 0.26/-0.72μA), prevalence of redox shuttlers (Fe-S proteins, cytochromes, quinones) facilitating enhanced electron transfer by minimization of associated losses and higher enzyme activities were observed with induction of anoxic phase. Anoxic condition shifts system microenvironment between oxidation and reduction assisting reduction of dye to its intermediates followed by their mineralization.

    The fundamental issue of the region of period formaton in a degenerate star is examined, with special attention given to the treatment of the Brunt-Vaisala frequency. It is shown that, in order to obtain reliable numerical results in degenerate stellar models, the Brunt-Vaisala frequency must be appropriately transformed, because it is defined in terms of a difference between two numbers which become nearly equal in highly degenerate matter, causing serious numerical problems and systematic errors. An alternative expression is derived, which is valid for multicomponent nonideal partially degenerate and partially ionized plasmas such as those encountered in white dwarf envelopes. This expression is used to compute the period structure of the same white dwarf considered by Pesnell (1987). It is shown that the implicit numerical differencing used in the Lagrangian pulsation code of Pesnell leads to very serious difficulties when used with models of degenerate stars.

    The aim of this study was to evaluate the effectiveness of endovascular repair in the treatment of isolated iliac artery aneurysm (IAA) using Excluder bifurcated endograft. Eight consecutive patients with IAA were treated during a period of 45 months using Excluder bifurcated endograft. Two patients presented with isolated IAA rupture and were treated emergently, whereas the other six patients underwent elective treatment. All aneurysms lacked sufficient proximal necks and therefore were not suitable for tubular-shaped endograft. Follow-up imaging was performed at 1 week, at every 3 months during the first year, semiannually until 2 years, and annually afterward using angio-computed axial tomography and plain films. Technical success was achieved in all patients. No mortality was seen despite two patients having IAA rupture. Follow-up (12 to 60 months) was done in all but one patient. During this period, complications were observed in three patients. One patient developed sexual impotence at 3-month follow up; one patient presented unilateral gluteal claudication after the procedure, which resolved at 3 months; and one patient developed a graft porosity-related endoleak, which was successfully managed with placement of an additional ipsilateral iliac extension. Endovascular treatment of isolated IAA using bifurcated endograft is safe and can be an alternative to surgical treatment. The benefits from decreased morbidity and mortality of endoluminal treatment of isolated IAA using bifurcated endograft outweigh the minor complications associated with this technique, which are mostly related to occlusion of hypogastric arteries.

    INTRODUCTION Chordomas are rare but aggressive tumors due to local recurrence and distant metastases. They originate commonly in the sphenooccipital and sacrococcygeal regions, and metastasize to the lungs, bone, skin, liver, and lymph nodes. They occur more frequently in men and people over the age of 40. PRESENTATION OF CASE A 28 year-old female presented with sacrococcygeal chordoma for which she received wide local excision and adjuvant radiation therapy. She enjoyed an unusual disease-free survival for 11 years until a routine surveillance scan of the pelvis identified local recurrence. Further work up revealed bilateral pulmonary metastases. She underwent local excision of the recurrent tumor and video-assisted thoracoscopic (VATS) wedge resection of pulmonary metastases. She also received adjuvant radiation therapy to the recurrent resection bed. Two years later, she remains free of disease and symptoms. DISCUSSION Chordomas are commonly insensitive to chemotherapy and radiation, making surgery the most successful therapeutic modality. However, there are few guidelines on the surveillance and treatment of recurrent chordoma. We report success with aggressive surgical resection of recurrence and metastasis as well as adjuvant radiation therapy. CONCLUSION The prolonged survival of our patient underscores the importance of (1) aggressive surgical resection of chordoma, whether primary, recurrent, or metastatic, with adjuvant radiation therapy, (2) minimization of surgical seeding of tumor, and (3) diligent cancer surveillance.

    The first results of the PREDIMED (PREvencion con Dieta MEDiterranea) randomized trial, after 3-month intervention, showed that the Mediterranean Diet (MD), supplemented with either virgin olive oil (VOO) or nuts, reduced systolic blood pressure, serum cholesterol and triacylglycerol (TG) concentrations and increased high-density lipoprotein (HDL)-cholesterol when compared to a control (low-fat diet) group. Serum TG levels are an independent risk factor for coronary heart disease and are strongly determined by very low-density lipoprotein (VLDL) composition, which can be specifically modified by dietary lipid source. Within the context of the PREDIMED study, we assessed the VLDL composition in 50 participants after 3 months of intake of two MD, supplemented with VOO or nuts, compared with a low-fat diet. Total and low-density lipoprotein cholesterol concentrations were reduced in subjects on the MD+nuts, whereas HDL-cholesterol increased after consumption of the MD+VOO. Serum TG concentrations were significantly lowered in both intervention groups (either the MD+nuts or MD+VOO). However, only the MD+VOO reduced the VLDL-cholesterol and VLDL-TG content and the TG/apolipoprotein B ratio in VLDL, which was used to estimate particle size. Although VLDL-TG fatty acids were very slightly modified, VLDL-TG molecular species in VLDL after consumption of the MD+nuts were characterized by a higher presence of linoleic acid (18:2, n-6), whereas after the intake of MD+VOO, they were rich in oleic acid (18:1, n-9). Therefore, we conclude that the reduction in systemic TG concentrations observed after consumption of the MD may be explained by reduction of the lipid core of VLDL and a selective modification of the molecular species composition in the particle.

    The source water in one forest region of the Northeast China had very high natural organic matter (NOM) concentration and heavy color during snowmelt period. The efficiency of five combined treatment processes was compared to address the high concentration of NOM and the mechanisms were also analyzed. Conventional treatment can hardly remove dissolved organic carbon (DOC) in the source water. KMnO4 pre-oxidization could improve the DOC removal to 22.0%. Post activated carbon adsorption improved the DOC removal of conventional treatment to 28.8%. The non-sufficient NOM removal could be attributed to the dominance of large molecular weight organic matters in raw water, which cannot be adsorbed by the micropore upon activated carbon. O3+activated carbon treatment are another available technology for eliminating the color and UV254 in water. However, its performance of DOC removal was only 36.4%, which could not satisfy the requirement for organic matter. The limited ozone dosage is not sufficient to mineralize the high concentration of NOM. Magnetic ion-exchange resin combined with conventional treatment could remove 96.2% of color, 96.0% of UV254 and 87.1% of DOC, enabling effluents to meet the drinking water quality standard. The high removal efficiency could be explained by the negative charge on the surface of NOM which benefits the static adsorption of NOM on the anion exchange resin. The results indicated that magnetic ion-exchange resin combined with conventional treatment is the best available technology to remove high concentration of NOM.

    A double-blind, randomized study was carried out in 37 patients with acne vulgaris to compare the efficacy of two similar lotion formulations, one with ('Actinac') and the other without chloramphenicol (4%). Patients used one or other of the two formulations twice daily for the first 4 days and then at night only for the remainder of the 3-month trial period. At the end of the first month's treatment, the group treated with the full formulation showed a statistically significant greater reduction in lesion count score than in the group receiving the formulation without chloramphenicol. Both treatments produced statistically significant reductions in lesion counts at all monthly follow-up visits. After 3-months' treatment, the mean lesion count score was reduced from 28.8 to 9.3 in the full formulation-treated group and from 39.5 to 14.3 in the formulation minus chloramphenicol group, but this difference did not reach statistical significance.

    Abstract To evaluate effectiveness of 23-valent pneumococcal polysaccharide vaccine (PPSV23) inoculated during defined “vaccination period,” first 6 months post cancer diagnosis (ie, an anti-cancer treatment period), in elderly lung cancer patients on community-acquired pneumonia (CAP) hospitalization incidence. This was a nationwide population-based cohort study of 157 newly diagnosed elderly lung cancer patients receiving PPSV23 during “vaccination period”, and 628 age and sex one-to-one matched controls enrolled in the National Health Insurance Research Database (NHIRD) of Taiwan between 2007 and 2010. All patients were ≥75 years old and still survival post “vaccination period.” Incidence density (ID) of all-cause inpatient CAP and cumulative survival risk were analyzed by multivariate Poisson regression and Kaplan–Meier method, respectively. After a 4-year follow-up, IDs of all-cause inpatient CAP for vaccination and control cohorts were 297 and 444 per 1000 PYs, respectively. Less vaccinated patients had CAP incidence density >1 time per PY (12.7% vs 21.2%) than non-vaccinated patients. After adjusting for potential confounding variables, like influenza vaccination, comorbidities, cancer treatment modalities, and socioeconomic status, adjusted inpatient CAP incidence rate in PPSV23 vaccination cohort was 0.74 times lower than control cohort (incidence rate ratio [IRR] = 0.740, P = 0.0339). Two-year cumulative CAP hospitalization rates and overall survival rates were 37.1% vs. 55.4%, and 46.6% vs. 26.2%, respectively, for lung cancer patients with and without PPSV23 (both P < 0.001). Subgroup analysis showed that for elderly lung cancer patients not ever receiving influenza vaccine, PPSV23 still had trend to reduce all-cause inpatient CAP. For elderly lung cancer patients aged ≥75 years, PPSV23 inoculated during anti-cancer treatment period could reduce CAP hospitalizations and improve survival. PMID:26131806

    This study investigates frequency and types of criminal convictions among a national sample of heroin users during a 3-year period prior to opioid maintenance treatment (OMT). All heroin users (N = 3,789) in Norway who applied for and were eligible for OMT (1997-2003) were included. The OMT records were cross-linked to Norwegian crime statistics. During observation, 24,478 convictions were recorded among 60.9% of the sample. Differences of criminal convictions were found within the group; a large proportion (39.1%) had no convictions, whereas 10% of the sample was responsible for 37.8% of all convictions. Convictions for acquisitive crimes and drug crimes were the most common. Variations in the cohort's individual crime sequences were found. The heavy involvement of heroin users with the criminal justice system provides an opportunity to intervene with dependent offenders. Coordination between treatment providers and police or courts can play an important role in improving outcomes through better access to treatment.

    Data from a randomized trial of oral periodic presumptive treatment (PPT) to reduce vaginal infections were analyzed to assess the effect of the intervention on a healthy vaginal environment (normal flora confirmed by Gram stain with no candidiasis or trichomoniasis). The incidence of a healthy vaginal environment was 608 cases per 100 person-years in the intervention arm and 454 cases per 100 person-years in the placebo arm (hazard ratio [HR], 1.36; 95% confidence interval [CI], 1.17-1.58). Sustained vaginal health (healthy vaginal environment for ≥3 consecutive visits) was also more frequent in the intervention arm (HR, 1.69; 95% CI, 1.23-2.33). PPT is effective at establishing and sustaining a healthy vaginal environment.

    Abstract The aim of this study was to evaluate the impact of white blood cell (WBC) counts at presentation on the achievement of deep molecular response. A total of 362 newly diagnosed chronic-phase chronic myeloid leukemia patients (CML-CP) receiving 400 mg/day imatinib were serially monitored for a median of 36 months (range 6–115). Patients showing an optimal response at 3, 6, and 12 months as defined by the 2013 European LeukemiaNet recommendations had significantly lower WBC counts at presentation than those showing nonoptimal responses (all P < 0.0001). Among the cutoff values with a similar Youden index, 150 × 10E9/L (abbreviated WBC > 150) was selected to identify the greatest amount of patients with the potential to achieve a sustained molecular response of 4.5 (MR4.5). Regardless of whether the Sokal risk score was included, the BCR-ABLIS value at 3 months, WBC counts at presentation, hemoglobin levels, and sex were the common independent predictors for an MR4.5, with the former 2 presenting the highest hazard risk. Low Sokal risk scores did not independently predict the achievement of an MR4.5. Patients with concurrent WBC > 150 and BCR-ABLIS ≤ 10% had a similar incidence of 4-year MR4.5 compared with patients with concurrent WBC ≤ 150 and BCR-ABLIS > 10% and concurrent WBC > 150 and BCR-ABLIS > 10% (13.5% vs 13.2% vs 8.8%, P = 0.47), and all of these values were significantly lower than the values for patients with concurrent WBC ≤ 150 and BCR-ABLIS ≤ 10% (55.0%, all P < 0.0001). Patients with concurrent WBC ≤ 150 and BCR-ABLIS ≤ 10% had better 4-year event-free survival rates, progression-free survival rates, and overall survival rates compared with patients with WBC > 150 or BCR-ABLIS > 10%. The combination of WBC count at presentation and BCR-ABLIS at 3 months provides improved predictions of deep molecular response in imatinib-treated CML-CP patients. Therefore, the WBC count at presentation might be used to

    Teachers and students often suffer from the same disaster. The prevalence of PTSD in students has been given great attention. However, in acting as mentors to students and their families, teachers are more likely to have vicarious and indirect exposure via hearing stories of their aftermath and witnessing the consequences of traumatic events. There are limited data pertaining to the prevalence of PTSD and its risk factors among teachers. A total of 316 teachers from 21 primary and secondary schools in Baoxing County were administered a project-developed questionnaire which included the items regarding demographic characteristics, earthquake-related experiences, somatic discomforts, emotional reactions, support status, and everyday functioning 2 weeks after the Lushan earthquake, and they finished a 1-to-1 telephone interview for addressing the PTSD criteria of the Mini International Neuropsychiatric Interview (MINI) 3 months after the earthquake. The prevalence of PTSD was 24.4% among teachers. Somatic discomforts (odds ratio [OR] 1.89, 95% confidence interval [CI] 1.06-3.37) were positive risk factors of PTSD. Perceived social support (OR 0.30, 95% CI 0.14-0.62) and being able to calm down (OR 0.25, 95% CI 0.09-0.75) in teaching were negative risk factors. PTSD is commonly seen among teachers after an earthquake, and risk factors of PTSD were identified. These findings may help those providing psychological health programs to find the teachers who are at high risk of PTSD in schools after an earthquake in China.

    Decolorized (purified, low anthraquinone) whole leaf Aloe vera (L.) Burm. f. juice was administered at concentrations of 0%, 0.5%, 1% and 2% in the drinking water of F344Du rats for 3 months without any adverse effect. The no-observed-adverse-effect level (NOAEL) in this study was considered to be >2%w/v (>1845 mg/kg bodyweight/day for males and >2920 mg/kg bodyweight for females). The test material contained total anthraquinones at <0.1 parts per million. In the present study there was a complete absence of any histological alteration in samples from the cecum, colon (proximal, mid and distal regions). Similar concentrations of non-decolorized (unpurified, high anthraquinone) Aloe vera extracts tested in other studies have resulted in an increased incidence and severity of diarrhea and colon adenomas and carcinomas. The results of this study supports the assertion that the high levels of anthraquinone present in orally administered, non-purified whole leaf Aloe vera extract may be responsible for the adverse effects observed on the colon.

    A low glycaemic index (LGI) diet during pregnancy complicated by gestational diabetes mellitus (GDM) may offer benefits to the mother and infant pair beyond those during pregnancy. We aimed to investigate the effect of an LGI diet during pregnancy complicated with GDM on early post-natal outcomes. Fifty-eight women (age: 23-41 years; mean ± SD pre-pregnancy body mass index: 24.5 ± 5.6 kg m(-2) ) who had GDM and followed either an LGI diet (n = 33) or a conventional high-fibre diet (HF; n = 25) during pregnancy had a 75-g oral glucose tolerance test and blood lipid tests at 3 months post-partum. Anthropometric assessments were conducted for 55 mother-infant pairs. The glycaemic index of the antenatal diets differed modestly (mean ± SD: 46.8 ± 5.4 vs. 52.4 ± 4.4; P < 0.001), but there were no significant differences in any of the post-natal outcomes. In conclusion, an LGI diet during pregnancy complicated by GDM has outcomes similar to those of a conventional healthy diet. Adequately powered studies should explore the potential beneficial effects of LGI diet on risk factors for chronic disease.

    Comparative studies of the potency of long- and short-acting erythropoiesis-stimulating agents (L-ESAs and S-ESAs) on erythropoietic activity in patients with chronic kidney disease without dialysis have not been performed, although L-ESAs are used in many countries. We performed a retrospective analysis of non-dialysis (ND) patients who had received L-ESA or S-ESA. More days were needed for the S-ESA-treated group (368 d) to reach the haemoglobin (Hb) reference range than for the L-ESA-treated group (126 d). Therefore, we investigated risk factors that influence the period until the Hb level reaches the reference range. Patients were classified into two groups by the period until the Hb level was stabilised within the reference range: the short- and long-term group. Two risk factors for delayed Hb stabilisation were identified: age ≥60 years; and administration of an S-ESA for initial treatment. These findings suggest that the Hb level should be carefully monitored during ESA therapy in elderly ND patients, and that the ESA dose should be increased or L-ESA therapy should be utilised to treat renal anaemia.

    The complex issues associated with barriers to treatment entry for parents who are involved with child welfare has not been well explored. Accessing timely treatment is now critical for these parents since the introduction of the Adoption and Safe Families Act of 1997, limiting the time until a permanency decision is made. Using a longitudinal, qualitative approach, substance-abusing parents from 15 families, their relevant family members, and service providers were interviewed approximately every 3 months over an 18-month period. The experiences of these parents add to our knowledge of the unique barriers this population faces, and expands our understanding of the mechanisms by which certain barriers may delay treatment.

    Background: The carpal tunnel syndrome (CTS) is the most common neuropathy. The aim of this study was to evaluate the effect of a new and noninvasive treatment including extracorporeal shock wave therapy (ESWT) in the treatment of CTS. Materials and Methods: This study is a clinical trial conducted on 60 patients with moderate CTS in selected health centers of Isfahan Medical University from November 2014 to April 2015. Patients with CTS were randomly divided into two groups. Conservative treatment including wrist splint at night for 3 months, consumption of nonsteroidal anti-inflammatory drugs for 2 weeks, and oral consumption of Vitamin B1 for a month was recommended for both groups. The first group was treated with ESWT, one session per week for 4 weeks. Focus probe with 0.05, 0.07, 0.1, and 0.15 energy and shock numbers 800, 900, 1000, and 1100 were used from the first session to the fourth, respectively. The evaluated parameters were assessed before treatment and after 3 and 6 months. Data were analyzed using SPSS version 19, Student’s t-test, and Chi-square test. Results: All parameters were significantly decreased in the ESWT group after 3 months. These results remained almost constant after 6 months compared with 3 months after treatment. However, only two parameters considerably improved after 3 months of treatment in the control group. The entire indexes in the control group implicated the regression of results in long-term period. Conclusion: It is recommended to use ESWT as a conservative treatment in patients with CTS. PMID:27563630

    Estragole is a natural organic compound that is used as an additive, flavoring agent, or fragrance in a variety of food, cleaning, and cosmetic products; as an herbal medicine; as an antimicrobial agent against acid-tolerant food microflora; and to produce synthetic anise oil. Estragole was nominated for toxicity testing by the National Institute of Environmental Health Sciences to characterize its toxicity when administered by gavage to F344/N rats and B6C3F1 mice and to determine how similar its effects might be to those of the structurally related compound, methyleugenol. Male and female F344/N rats and B6C3F1 mice were given estragole (greater than 99% pure) in corn oil by gavage for 3 months. Genetic toxicology studies were conducted in Salmonella typhimurium and mouse peripheral blood erythrocytes. Core and special study (rats only) groups of 10 male and 10 female rats and mice were administered 37.5, 75, 150, 300, or 600 mg estragole/kg body weight in corn oil by gavage, 5 days per week. The core study groups were given estragole for 3 months and the special study groups for 30 days. All core study rats survived the 3-month exposure period. Mean body weights of the 300 and 600 mg/kg groups were 73% to 92%, respectively, of those of the vehicle control groups. A staining pattern on the ventral surface anterior to the genitalia beginning at week 9 in the 300 and 600 mg/kg groups was attributed to residue of estragole or metabolites in the urine. Alterations in the erythron related to estragole administration occurred in male and female rats; male rats demonstrated a stronger response. The changes in the erythron were characterized as a microcytic, normochromic, nonresponsive anemia. There were decreases in serum iron concentration in the 300 mg/kg females and 600 mg/kg males and females. The average percent saturation of total iron binding capacity was decreased in the 600 mg/kg males and females. Dose-related increases in platelet counts occurred in most of

Estragole was nominated for toxicity testing by the National Institute of Environmental Health Sciences to characterize its toxicity when administered by gavage to F344/N rats and B6C3F1 mice and to determine how similar its effects might be to those of the structurally related compound, methyleugenol. Male and female F344/N rats and B6C3F1 mice were given estragole (greater than 99% pure) in corn oil by gavage for 3 months. Genetic toxicology studies were conducted in Salmonella typhimurium and mouse peripheral blood erythrocytes. Core and special study (rats only) groups of 10 male and 10 female rats and mice were administered 37.5, 75, 150, 300, or 600 mg estragole/kg body weight in corn oil by gavage, 5 days per week. The core study groups were given estragole for 3 months and the special study groups for 30 days. All core study rats survived the 3-month exposure period. Mean body weights of the 300 and 600 mg/kg groups were 73% to 92%, respectively, of those of the vehicle control groups. A staining pattern on the ventral surface anterior to the genitalia beginning at week 9 in the 300 and 600 mg/kg groups was attributed to residue of estragole or metabolites in the urine. Alterations in the erythron related to estragole administration occurred in male and female rats; male rats demonstrated a stronger response. The changes in the erythron were characterized as a microcytic, normochromic, nonresponsive anemia. There were decreases in serum iron concentration in the 300 mg/kg females and 600 mg/kg males and females. The average percent saturation of total iron binding capacity was decreased in the 600 mg/kg males and females. Dose-related increases in platelet counts occurred in most of

    This retrospective study included 23 necrotic immature permanent teeth treated for either short-term (treatment period <3 months) or long-term (treatment period >3 months) using conservative endodontic procedures with 2.5% NaOCl irrigations without instrumentation but with Ca(OH)(2) paste medication. For seven teeth treated short-term, the gutta-percha points were filled onto an artificial barrier of mineral trioxide aggregate (MTA). For 16 teeth treated long-term, the gutta-percha points, amalgam, or MTA were filled onto the Ca(OH)(2)-induced hard tissue barrier in the root canal. We found that all apical lesions showed complete regression in 3 to 21 (mean, 8) months after initial treatment. All necrotic immature permanent teeth achieved a nearly normal root development 10 to 29 (mean, 16) months after initial treatment. We conclude that immature permanent teeth with pulp necrosis and apical pathosis can still achieve continued root development after proper short-term or long-term regenerative endodontic treatment procedures.

    Teachers and students often suffer from the same disaster. The prevalence of PTSD in students has been given great attention. However, in acting as mentors to students and their families, teachers are more likely to have vicarious and indirect exposure via hearing stories of their aftermath and witnessing the consequences of traumatic events. There are limited data pertaining to the prevalence of PTSD and its risk factors among teachers. A total of 316 teachers from 21 primary and secondary schools in Baoxing County were administered a project-developed questionnaire which included the items regarding demographic characteristics, earthquake-related experiences, somatic discomforts, emotional reactions, support status, and everyday functioning 2 weeks after the Lushan earthquake, and they finished a 1-to-1 telephone interview for addressing the PTSD criteria of the Mini International Neuropsychiatric Interview (MINI) 3 months after the earthquake. The prevalence of PTSD was 24.4% among teachers. Somatic discomforts (odds ratio [OR] 1.89, 95% confidence interval [CI] 1.06-3.37) were positive risk factors of PTSD. Perceived social support (OR 0.30, 95% CI 0.14-0.62) and being able to calm down (OR 0.25, 95% CI 0.09-0.75) in teaching were negative risk factors. PTSD is commonly seen among teachers after an earthquake, and risk factors of PTSD were identified. These findings may help those providing psychological health programs to find the teachers who are at high risk of PTSD in schools after an earthquake in China. PMID:27442675

    Warfarin dosage estimation using the pharmacogenetic algorithms has been shown to improve the quality of anticoagulation control in patients with atrial fibrillation. We sought to assess the genetic, demographic and clinical factors that determine the quality of anticoagulation in patients following aortic valve replacement (AVR). We studied 200 consecutive patients (130 men) aged 63 ± 12.3 years, undergoing AVR, in whom warfarin dose was established using a pharmacogenetic algorithm. The quality of anticoagulation within the first 3 months since surgery was expressed as the time of international normalized ratio (INR) in the therapeutic range (TTR). The median TTR in the entire cohort was 59.6% (interquartile range, 38.7 - 82.7). Ninety-nine (49.5%) patients with TTR ≥ 60% did not differ from those with poor anticoagulation control (TTR < 60%) with regard to demographic and cardiovascular risk factors. Coronary artery disease (n = 84, 42%) and previous stroke (n = 5, 2.5%) predicted higher TTR, while possession of CYP2C9*2 variant allele (n = 49, 25%) was associated with lower TTR (P = 0.01). In turn, VKORC1 c.-1639A, CYP2C9*2 and *3 variants were independently associated with actual warfarin dose (P < 0.0001). In AVR patients better anticoagulation control is observed in patients with coronary artery disease and history of stroke, which might result in part from previous lifestyle modification and therapy. Possession of CYP2C9*2 and/or CYP2C9*3 allele variants is associated with lower TTR values and warfarin dose variations in AVR patients, the latter affected also by VKORC1 c.-1693G>A polymorphism.

    Background SoloSTAR® (SOL; sanofi-aventis, Paris, France) is a prefilled insulin pen device for the injection of insulin glargine and insulin glulisine. This is the first Australian survey to determine its usability, participant acceptance, and safety in clinical practice. Methods A 3-month, nonrandomized, noncomparative, observational survey in Australia was conducted in individuals with diabetes. Participants were given SOL pens containing glargine, the instruction leaflet, and a toll-free helpline number. Training was offered to all participants. Safety data, including product technical complaints (PTCs), were gathered from ongoing feedback given by the participant or health care professional (HCP) and by independent interviews conducted 6–10 weeks after study start. Results Some 2674 people consented to take part across 93 sites (150 HCPs), and 2029 participated in interviews. Of these, 52.6% had type 1 diabetes, 16.3% had manual dexterity problems, and 15.5% had poor eyesight not corrected by glasses. At the time of interview, 96.8% of participants were still using SOL. None of the eight PTCs reported were due to technical defects; most were related to handling errors. Some 62 participants reported 77 adverse events; none were related to a PTC. The vast majority of participants (95.4%) were “very satisfied” or “satisfied” with using SOL, and 89.7% of the participants had no questions or concerns using SOL on a daily basis. Similar positive findings were reported by participants with manual or dexterity impairments. Conclusions In this survey of everyday clinical practice, SOL had a good safety profile and was very well accepted by participants. PMID:20144398

    The prevalence of trimethoprim (TMP) and sulfamethoxazole (SMX) resistance in commensal E. coli from pigs was tested in this study. E. coli was derived from three groups of piglets in successive stages of metaphylactic therapy and from two groups of sows 10 and 18 weeks after the treatment. MIC values of TMP and SMX were determined for a total of 352 strains. The presence of resistance genes (dfrA1, dfrA5, dfrA7, dfrA12, dfrA17, sul1, sul2, sul3) and class 1 and 2 integron-associated dfrA gene cassettes was tested. Resistance to TMP was very high during the administration of the antimicrobial (from 97 to 100%) and amounted to 86% and 69% in the post-exposure period; MIC > 32 mg/L. The isolates from all groups of pigs were resistant to sulfamethoxazole, with MIC > 1028 mg/L. The dfrA1 and sul1 genes (as part of integrons) dominated in E. coli from piglets, but the dfrA12 and sul1 genes were prevalent in E. coli from sows. Coexistence of the different dfrA genes was detected in 71 isolates from all groups of swine. Transcription analysis revealed that most of these genes were not transcribed, particularly gene cassettes of class 1 integrons. The research revealed a high level of resistance associated with the metaphylactic treatment, persistence and circulation of resistance in bacterial populations. Diverse genetic background with multiple and not transcribed resistance genes was observed. PMID:25689993

    Enzyme replacement therapy (ERT) with exogenous glucocerebrosidase is indicated to treat symptomatic Gaucher disease (GD), a rare, inherited metabolic disorder. ERT with velaglucerase alfa, which is produced in a human cell line using gene activation technology, was studied in a 12-month phase III trial in Japanese patients with type 1 or 3 GD who were switched from imiglucerase ERT (n=6); the current, open-label, 12-month extension study was designed to assess longer-term safety and efficacy. Two adult and three pediatric patients (aged <18years) were enrolled into the extension study. Every-other-week intravenous infusions were administered for 63-78weeks at average doses between 51.5 and 60.7units/kg. Three non-serious adverse events were considered related to velaglucerase alfa treatment, but no patient discontinued from the study. Six serious but non-drug-related adverse events were reported. No patient tested positive for anti-velaglucerase alfa antibodies. Hemoglobin concentrations, platelet counts, and liver and spleen volumes (normalized to body weight) in these patients were generally stable over a cumulative 24-month period from the baseline of the parent trial. The data suggest that velaglucerase alfa was well tolerated and maintained clinical stability in Japanese GD patients over 2years after switching from imiglucerase.

    An anaerobic sequencing batch reactor (AnSBR) was used to treat the dissolved air flotation skimmings from a cooked pork meat plant. During the start-up period, the reactor was operated in fed-batch mode for 25 days and 7 batches were treated. The SBR was inoculated with sludge taken from a reactor treating distillery vinasse. The results showed that this kind of sludge is a very good source of inoculum for digesters treating residues with a high content in fats and long-chain fatty acids because it was able to adapt very rapidly to the new substrate and, from the second batch on, the sludge was already able to metabolize the fatty residue at quite high rates. The AnSBR was then operated with 5 batches per week for 110 days and the quantity of VS added per batch was regularly increased until the maximum treatment capacity of the reactor (i.e. maximum loading rate) was reached. The maximum organic loading rates were found to be 0.16 g VS/g VSS d, or 0.224 g VS/g VSS.batch when the reactor is fed 5 times a week. The biodegradability of the skimmings was very high, with more than 97% of TS removal, and the methane production was 880+/-90 mL of methane/g of VS(added).

    This randomized, observer-blind, split-face study assessed the irritation potential and likelihood of continued use of clindamycin phosphate 1.2%--benzoyl peroxide (BPO) 2.5% gel or adapalene 0.1%--BPO 2.5% gel once daily over a 14-day treatment period in 21 participants (11 males; 10 females) with acne who were 18 years or older. Investigator clinical assessment (erythema and dryness) and self-assessment (dryness and burning/stinging) were performed at baseline and each study visit (days 1-14) using a 4-point scale (O = none; 3 = severe). Transepidermal water loss (TEWL) and corneometry measurements were performed at baseline and days 3, 5, 7, 9, 11, and 14. Lesions were counted at baseline and on day 14. Participant satisfaction questionnaires were completed on days 7 and 14. At the end of the study, investigators reported none or only mild erythema in 86% (18/21) of participants treated with clindamycin phosphate 1.2%--BPO 2.5% gel compared with 62% (13/21) of participants treated with adapalene 0.1%--BPO 2.5% gel. No severe erythema was reported with clindamycin phosphate 1.2%--BPO 2.5% gel. Adapalene 0.1%--BPO 2.5% gel was prematurely discontinued due to severe erythema in 1 participant on day 5 and a second participant on day 9. Additionally, 2 more participants reported severe erythema on day 14. Mean erythema scores were 0.9 (mean change from baseline, 0.7) with clindamycin phosphate 1.2%--BPO 2.5% gel and 1.4 (mean change from baseline, 1.3) with adapalene 0. 1%--BPO 2.5% gel on day 14 (P < .05 for days 6-14). Similar results were seen with dryness. Mean scores were 0.5 (mean change from baseline, 0.4) and 1.0 (mean change from baseline, 1.0), respectively (P < .05 for days 6-14). Self-assessment, TEWL, and corneometry results underscored the investigator clinical assessment. Participant preference and likelihood of continued usage was greater with clindamycin phosphate 1.2%--BPO 2.5% gel. Continued use and efficacy results for the treatment of acne were

    Recently, various video-assisted thoracoscopic surgical techniques have been reported with occasional success in treating hepatic hydrothorax (HH). In 2 patients with refractory HH, we applied a combination of four therapeutic modalities as a single procedure named as a "four-step approach": (1) pneumoperitoneum for localization of diaphragmatic defects, (2) thoracoscopic pleurodesis, (3) postoperative continuous positive airway pressure, and (4) drainage of ascites for abdominal decompression. The treatment was successful in both patients, without recurrence during the follow-up period of 24 and 3 months, respectively.

    Background: Chronic subdural hematoma (CSDH) is frequent pathology in neurosurgical practice. The aim of this study is to present the first series of patients with CSDH, who got surgically treated in Clinic of Neurosurgery, University Clinical Center of Kosovo. Materials and Methods: This is a retrospective study that included 137 patients with CSDH who had been treated during the period 2008–2012. The data were collected and analyzed from the archives and protocols of the University Clinical Center of Kosovo. Patients were analyzed in many aspects such as age, gender, etiological factors, clinical features, localization, diagnoses, methods of surgical interventions, recurrences and mortality of patients. Results: From 137 patients with CSDH, 106 (77.3%) were males and 31 (22.7%) females. Average age of patients was 62.85 years. Analyzed according to the decades, the highest number of causes with CSDH was between 70 and 79 years (46%). The head trauma has been responsible for CSDH in 88 patients (64.3%), while the main symptom was headache (92 patients or 67.1%). One burr-hole trepanation with closed drainage system has been used in majority of cases (in 101 patients or 73.7%). The recurrence of CSDH was 6.5%, whereas mortality 2.9%. Conclusion: CSDH is more common in elderly patients. The male-female ratio is 3.4:1. Like other authors we also think that treatment with one burr-hole and drainage is a method of choice, because of its simplicity and safety. PMID:25883478

    Periodic polymers can be made by self assembly, directed self assembly and by photolithography. Such materials provide a versatile platform for 1, 2 and 3D periodic nano-micro scale composites with either dielectric or impedance contrast or both, and these can serve for example, as photonic and or phononic crystals for electromagnetic and elastic waves as well as mechanical frames/trusses. Compared to electromagnetic waves, elastic waves are both less complex (longitudinal modes in fluids) and more complex (longitudinal, transverse in-plane and transverse out-of-plane modes in solids). Engineering of the dispersion relation between wave frequency w and wave vector, k enables the opening of band gaps in the density of modes and detailed shaping of w(k). Band gaps can be opened by Bragg scattering, anti-crossing of bands and discrete shape resonances. Current interest is in our group focuses using design - modeling, fabrication and measurement of polymer-based periodic materials for applications as tunable optics and control of phonon flow. Several examples will be described including the design of structures for multispectral band gaps for elastic waves to alter the phonon density of states, the creation of block polymer and bicontinuous metal-carbon nanoframes for structures that are robust against ballistic projectiles and quasi-crystalline solid/fluid structures that can steer shock waves.

    Purpose The association between initial molecular response and longer-term outcomes with nilotinib was examined. Patients and Methods Patients with imatinib-resistant or -intolerant chronic myeloid leukemia in chronic phase from the phase II nilotinib registration study with available postbaseline BCR-ABL1 transcript assessments were included (N = 237). Results BCR-ABL1 transcript levels (International Scale [IS]) at 3 months correlated with complete cytogenetic response (CCyR) by 24 months. Patients with BCR-ABL1 (IS) of > 1% to ≤ 10% at 3 months with nilotinib had higher cumulative incidence of CCyR by 24 months than patients with BCR-ABL1 (IS) of > 10% (53% v 16%). BCR-ABL1 (IS) at 3 months predicted major molecular response (MMR) by 24 months. Cumulative incidence of MMR by 24 months for patients with BCR-ABL1 (IS) of > 0.1% to ≤ 1%, > 1% to ≤ 10%, and > 10% was 65%, 27%, and 9%, respectively. These differences were observed for patients with or without baseline BCR–ABL1 mutations and for those with imatinib resistance or intolerance. Estimated event-free survival (EFS) rates at 24 months decreased with higher transcript levels at 3 months; patients with BCR-ABL1 (IS) of ≤ 1% had an estimated 24-month EFS rate of 82%, compared with 70% for patients with BCR-ABL1 (IS) of > 1% to ≤ 10% and 48% for patients with BCR-ABL1 (IS) of > 10%. Conclusion Patients with BCR-ABL1 (IS) of > 10% at 3 months had a lower cumulative incidence of CCyR and MMR and lower rates of EFS versus patients with BCR-ABL1 (IS) of ≤ 10%. Prospective studies may determine whether close monitoring or alternative therapies are warranted for patients with minimal initial molecular response. PMID:23109697

    ABSTRACT Objective To investigate the impact of diameter of needles on the effect of dry needling treatment of chronic lumbar myofascial pain syndrome. Design Forty-eight patients with chronic lumbar myofascial pain syndrome were randomly allocated to 3 groups. They received dry needling with needles of diameter 0.25 (group A), 0.5 (group B), and 0.9 mm (group C). Visual analog scale evaluation and health survey were conducted at baseline and 3 months after the treatment. Results Visual analog scale scores were significantly different in all groups from baseline to 3 months. Visual analog scale scores at 3 months showed differences between group C and the other 2 groups. When baseline and 3 months after treatment (0 day and 3 months) in each of the 3 groups was compared, there was a difference between group C and group B. The Short Form (36) Health Survey scores from baseline to 3 months were different within the treatment groups. Conclusions Visual analog scale score evaluations at 3 months showed efficacy in all groups. Results of 3 months showed that efficacy of treatment with larger needles (0.9-mm diameter) was better than that of smaller ones (0.5-mm diameter). The Short Form (36) Health Survey scores at 3 months indicated that treatments with needles of varying diameters were all effective, and when the results of 3 months were compared, there was no difference between the 3 groups.

    A double-blind, randomized trial was carried out in 44 patients with acne vulgaris to assess the effectiveness of two similar topical combination preparations, one containing hydrocortisone acetate ('Actinac') and the other without the steroid, when applied in lotion form. Patients used one or other of the two formulations twice daily for the first 4 days and then at night only for the remainder of the 3-month study period. The results showed that both treatments were effective but the full formulation-treated group showed a better response at the end of the first month's treatment in terms of percentage reduction in lesion count score, although this did not reach statistical significance. After 3 months, the average lesion count scores dropped from 82 to 11 in the full formulation and from 81 to 8 in the formulation minus hydrocortisone group.

    Context Lumbar diskectomy is the most common surgical procedure performed for back and leg symptoms in US patients, but the efficacy of the procedure relative to nonoperative care remains controversial. Objective To assess the efficacy of surgery for lumbar intervertebral disk herniation. Design, Setting, and Patients The Spine Patient Outcomes Research Trial, a randomized clinical trial enrolling patients between March 2000 and November 2004 from 13 multidisciplinary spine clinics in 11 US states. Patients were 501 surgical candidates (mean age, 42 years; 42% women) with imaging-confirmed lumbar intervertebral disk herniation and persistent signs and symptoms of radiculopathy for at least 6 weeks. Interventions Standard open diskectomy vs nonoperative treatment individualized to the patient. Main Outcome Measures Primary outcomes were changes from baseline for the Medical Outcomes Study 36-item Short-Form Health Survey bodily pain and physical function scales and the modified Oswestry Disability Index (American Academy of Orthopaedic Surgeons MODEMS version) at 6 weeks, 3 months, 6 months, and 1 and 2 years from enrollment. Secondary outcomes included sciatica severity as measured by the Sciatica Bothersomeness Index, satisfaction with symptoms, self-reported improvement, and employment status. Results Adherence to assigned treatment was limited: 50% of patients assigned to surgery received surgery within 3 months of enrollment, while 30% of those assigned to nonoperative treatment received surgery in the same period. Intent-to-treat analyses demonstrated substantial improvements for all primary and secondary outcomes in both treatment groups. Between-group differences in improvements were consistently in favor of surgery for all periods but were small and not statistically significant for the primary outcomes. Conclusions Patients in both the surgery and the nonoperative treatment groups improved substantially over a 2-year period. Because of the large numbers of

    We assess the consequences of the interface model-embedded-cluster or periodic-slab model-on the ability of DFT calculations to describe charge transfer (CT) in a particularly challenging case where periodic-slab calculations indicate a delocalized charge-transfer state. Our example is Cu atom adsorption on ZnO(10(1)0), and in fact the periodic slab calculations indicate three types of CT depending on the adsorption site: full CT, partial CT, and no CT. Interestingly, when full CT occurs in the periodic calculations, the calculated Cu atom adsorption energy depends on the underlying ZnO substrate supercell size, since when the electron enters the ZnO it delocalizes over as many atoms as possible. In the embedded-cluster calculations, the electron transferred to the ZnO delocalizes over the entire cluster region, and as a result the calculated Cu atom adsorption energy does not agree with the value obtained using a large periodic supercell, but instead to the adsorption energy obtained for a periodic supercell of roughly the same size as the embedded cluster. Different density functionals (of GGA and hybrid types) and basis sets (local atom-centered and plane-waves) were assessed, and we show that embedded clusters can be used to model Cu adsorption on ZnO(10(1)0), as long as care is taken to account for the effects of CT.

    The objective of this study was to evaluate in a sheep model the performance of a new polypropylene mesh (TVTx), which is intended as a less invasive treatment for female stress urinary incontinence. Eight female sheep were used in this study, each one being implanted with eight TVTx samples. At each time-point (weeks 1, 2, 4, and 12) seven TVTx were pulled out, while one TVTx was carefully dissected for histological investigations. One TVTx and one TVT, moreover, were inserted and immediately pulled out for obtaining the initial pullout forces in all sheep. The initial pullout values of TVT and TVTx were overlapping. The pullout forces of TVTx were >5 N (500 g) and increasing from weeks 1 to 12 (p<0.001). Histology revealed good tissue integration of TVTx in the tissue within 12 weeks after implantation. No abnormal histological findings were observed. This data could support the realization of a clinical trial with the TVTx mesh. PMID:16628374

    Purpose. RPE65 function is necessary in the retinal pigment epithelium (RPE) to generate chromophore for all opsins. Its absence results in vision loss and rapid cone degeneration. Recent Leber congenital amaurosis type 2 (LCA with RPE65 mutations) phase I clinical trials demonstrated restoration of vision on RPE65 gene transfer into RPE cells overlying cones. In the rd12 mouse, a naturally occurring model of RPE65-LCA early cone degeneration was observed; however, some peripheral M-cones remained. A prior study showed that AAV-mediated RPE65 expression can prevent early cone degeneration. The present study was conducted to test whether the remaining cones in older rd12 mice can be rescued. Methods. Subretinal treatment with the scAAV5-smCBA-hRPE65 vector was initiated at postnatal day (P)14 and P90. After 2 months, electroretinograms were recorded, and cone morphology was analyzed by using cone-specific peanut agglutinin and cone opsin–specific antibodies. Results. Cone degeneration started centrally and spread ventrally, with cells losing cone-opsin staining before that for the PNA-lectin–positive cone sheath. Gene therapy starting at P14 resulted in almost wild-type M- and S-cone function and morphology. Delaying gene-replacement rescued the remaining M-cones, and most important, more M-cone opsin–positive cells were identified than were present at the onset of gene therapy, suggesting that opsin expression could be reinitiated in cells with cone sheaths. Conclusions. The results support and extend those of the previous study that gene therapy can stop early cone degeneration, and, more important, they provide proof that delayed treatment can restore the function and morphology of the remaining cones. These results have important implications for the ongoing LCA2 clinical trials. PMID:21169527

    The maintenance of the effects of Cerebrolysin, a peptidergic compound with neurotrophic activity, on cognitive performance and qEEG activity was investigated through a 12-week, open-label extension of a 4-week, randomised, placebo-controlled pilot study. Thirty-three out of 41 patients with mild-to-moderate severe probable vascular dementia (VaD) according to NINDS-AIREN participating in the double-blind phase of the study were also assessed at the follow-up visit at week 16. Patients received i.v. infusions of Cerebrolysin (10 or 30 mL) or placebo (saline) 5 days/week for 4 weeks. Neuropsychological evaluations and qEEG recordings were done at baseline, week 4 and week 16. The mean change in score from baseline in the ADAS-cog+ and the slow-to-fast qEEG power ratio (PR), used as an index of qEEG slowing, were the two primary endpoints. Correlations between changes in cognition and qEEG induced by the treatment were also assessed. At the week 16 follow-up visit, Cerebrolysin improved (p<0.05) cognitive performance at the 10-mL and 30-mL doses and reduced qEEG slowing significantly (p<0.05) at the 30-mL dose with respect to the placebo. In addition, a significant (p<0.05) positive correlation between the change from the baseline qEEG PR and ADAS-cog+ variables was observed at week 16. These results indicate a persistence of the beneficial effects of Cerebrolysin on cognition and qEEG activity in VaD patients for at least 12 weeks after treatment cessation, and they suggest the potential utility of qEEG parameters as biomarkers for VaD clinical trials.

    To study adherence to product use prior to a Phase I microbicide trial, we recruited young men who have sex with men (YMSM) with a history of unprotected receptive anal intercourse (RAI) and provided them with 40 rectal applicators containing a placebo gel to use prior to RAI during a 12-week period. Ninety-five YMSM completed the trial. Based on a Computer Assisted Self Interview, 83 participants had receptive anal intercourse (RAI) (Median 12 occasions) using gel on 82.4% of occasions (SD 26.7; 0–100). Based on an interactive voice response system, 88 participants had RAI (Median 10 occasions) using gel on 87.9% of occasions (SD 20.0; 20–100). By applicator counts the median gel use was 12. Participants showed high adherence to gel use. Those who did not use the product consistently (n=40) adduced not having it with them (85%), forgetting to use it (48%), not wanting to use it (13%), partner refusal (10%) and gel messiness (10%).

    Childhood/adolescent antipsychotic drug (APD) use is exponentially increasing worldwide, despite limited knowledge of the long-term effects of early APD treatment. Whilst investigations have found that early treatment has resulted in some alterations to dopamine and serotonin neurotransmission systems (essential to APD efficacy), there have only been limited studies into potential long-term behavioural changes. This study, using an animal model for childhood/adolescent APD treatment, investigated the long-term effects of aripiprazole, olanzapine and risperidone on adult behaviours of male and female rats. Open-field/holeboard, elevated plus maze (EPM), social interaction and forced swim (FS) tests were then conducted in adult rats. Our results indicated that in the male cohort, early risperidone and olanzapine treatment elicited long-term hyper-locomotor effects (open-field/holeboard and FS tests), whilst a decrease in depressive-like behaviour (in FS test) was observed in response to olanzapine treatment. Furthermore, anxiolytic-like behaviours were found following testing in the open-field/holeboard and EPM in response to all three drug treatments. Effects in the female cohort, however, were to a far lesser extent, with behavioural attributes indicative of an increased depressive-like behaviour and hypo-locomotor activity exhibited in the FS test following early risperidone and olanzapine treatment. These results suggest that various APDs have different long-term effects on the behaviours of adult rats.

    In obese individuals, weight loss might be affected by variants of the adipokine-encoding genes. We verified whether selected functional single nucleotide polymorphisms in LEP, LEPR and ADIPOQ are associated with changes in serum levels of the respective adipokines and weight loss in 100 prepubertal obese (SDS-BMI > 2) Caucasian children undergoing lifestyle intervention. Frequencies of the -2548G > A LEP, Q223R LEPR, K656N LEPR, -11377C > G and -11426A > G ADIPOQ polymorphisms were analyzed by restriction fragment length polymorphism. Serum adipokine and soluble leptin receptor (sOB-R) concentrations were measured using the ELISA method. Among the analyzed polymorphisms, only LEPR polymorphisms were associated with changes of SDS-BMI or sOB-R concentrations in children after therapy. Carriers of the wild-type K665N and at least one minor Q223R allele had the greatest likelihood of losing weight (OR = 5.09, p = 0.006), an increase in sOB-R (ptrend = 0.022) and decrease in SDS-BMI correlated with the decrease of fat mass (p < 0.001). In contrast, carrying of the wild-type Q223R and at least one minor K665N allele were associated with a decrease in sOB-R concentrations and a decrease in SDS-BMI correlated with a decrease in fat-free mass (p = 0.002). We suggest that the combination of different LEPR variants, not a single variant, might determine predisposition to weight loss in the prepubertal period. PMID:27240401

    A case of thyrotoxic periodic paralysis is reported in a Hispanic man with an unusual recurrence six weeks after radioactive iodine treatment. Thyrotoxic periodic paralysis has now been well characterized in the literature: it occurs primarily in Orientals with an overwhelming male preponderance and a higher association of specific HLA antigens. Clinical manifestations include onset after high carbohydrate ingestion or heavy exertion, with progressive symmetric weakness leading to flaccid paralysis of the extremities and other muscle groups, lasting several hours. If hypokalemia is present, potassium administration may help abort the attack. Although propranolol can be efficacious in preventing further episodes, the only definitive treatment is establishing a euthyroid state. The pathophysiology is still controversial, but reflects altered potassium and calcium dynamics as well as certain morphologic characteristics within the muscle unit itself.

    This study examines the performance of an anaerobic fixed-film bioreactor under seasonal operating conditions prevailing in medium and small size Tequila factories: start-up, normal operation and particularly, during the restart-up after a long stop and starvation period. The proposed start-up procedure attained a stable biofilm in a rather short period (28 days) despite unbalanced COD/N/P ratio and the use of non-acclimated inoculum. The bioreactor was restarted-up after being shut down for 6 months during which the inoculum starved. Even when biofilm detachment and bioreactor clogging were detected at the very beginning of restart-up, results show that the bioreactor performed better as higher COD removal and methane yield were attained. CE-SSCP and Q-PCR analyses, conducted on the biofilm prokaryotic communities for each operating condition, confirmed that the high COD removal results after the bioreactor clogging and the severe starvation period were mainly due to the stable archaeal and resilient bacterial populations.

    During a 17-month period we treated in situ 334 patients with ureteric stones with a second-generation electromagnetic lithotriptor. Anxiety and discomfort were relieved with diazepam and pethidine chloride only. Ureteral stenting was used in 8.1% of upper, 36.4% of mid- and 5.7% of lower ureteric stones. The retreatment rate was 15%, but no patient had more than 3 sessions. The success rate of the treatment at 3 months was 88% for upper, 65% for mid- and 83% for lower ureteric stones. Open surgery had to be performed in 5 cases and ureteroscopies in 6 cases.

    The present study evaluated the effectiveness of a modified One Session Treatment (OST), which included an e-therapy homework maintenance program over 4 weeks for Blood-Injection-Injury (BII) phobia in children and adolescents. Using a single case, non-concurrent multiple-baseline design, 24 children and adolescents (8-18 years; 7 males, 17 females) with a primary diagnosis of BII phobia were randomly assigned to a one, two or three week baseline prior to receiving OST. Primary outcome measures included diagnostic severity, diagnostic status, and child and parent fear ratings. Secondary outcome measures included avoidance during behavioural avoidance tasks (BAT), global functioning and self and parent reported anxiety, fear and depression. Efficacy was assessed at post-treatment, 1-month, and 3-month follow-up. BII symptoms and diagnostic severity remained relatively stable during the baseline periods and then significantly improved following implementation of the intervention. Treatment response was supported by changes across multiple measures, including child, parent and independent clinician ratings. At post-treatment 8 of the 24 (33.33%) children were BII diagnosis free. Treatment gains improved at follow-ups with 14 (58.33%) children diagnosis free at 1-month follow-up and 15 (62.5%) diagnosis free at 3-month follow-up. Preliminary findings support the effectiveness of a modified OST approach for BII phobic youth with treatment outcomes improving over follow-up intervals. PMID:26313620

Methods over a period of four years, 16 patients underwent surgical treatment, and in its entirety belonged to stages III and IV of the classification proposed by Tubiana et al. We performed measurements of the extension deficit of the metacarpophalangeal joints, proximal and distal interphalangeal in preoperative, postoperative (3 months) and late postoperative period (5–8 years). Angles greater than 30° metacarpophalangeal joints and 15° proximal interphalangeal the results were considered surgical recurrence. Results there was obtained an average of 6.3° at the metacarpophalangeal joint, 13.8° in the proximal interphalangeal and distal interphalangeal at 1.9°. Conclusion the modified open palm technique is an effective method in the surgical treatment of severe contractures in Dupuytren's disease. PMID:26229769

    Purpose: To examine whether treatment workload and complexity associated with palliative radiation therapy contribute to medical errors. Methods and Materials: In the setting of a large academic health sciences center, patient scheduling and record and verification systems were used to identify patients starting radiation therapy. All records of radiation treatment courses delivered during a 3-month period were retrieved and divided into radical and palliative intent. 'Same day consultation, planning and treatment' was used as a proxy for workload and 'previous treatment' and 'multiple sites' as surrogates for complexity. In addition, all planning and treatment discrepancies (errors and 'near-misses') recorded during the same time frame were reviewed and analyzed. Results: There were 365 new patients treated with 485 courses of palliative radiation therapy. Of those patients, 128 (35%) were same-day consultation, simulation, and treatment patients; 166 (45%) patients had previous treatment; and 94 (26%) patients had treatment to multiple sites. Four near-misses and 4 errors occurred during the audit period, giving an error per course rate of 0.82%. In comparison, there were 10 near-misses and 5 errors associated with 1100 courses of radical treatment during the audit period. This translated into an error rate of 0.45% per course. An association was found between workload and complexity and increased palliative therapy error rates. Conclusions: Increased complexity and workload may have an impact on palliative radiation treatment discrepancies. This information may help guide the necessary recommendations for process improvement for patients who require palliative radiation therapy.

    Completely scripted treatment courses for verbatim interventions are uncommon in the field of clinical hypnosis. This approach was adopted for by a North Carolina research team for treating gastrointestinal disorders 20 years ago and has been used in hypnosis treatment of irritable bowel syndrome and ulcerative colitis, as well as in guided imagery treatment for functional abdominal pain. Treatment with these scripted protocols is delivered in a fixed series of sessions over a 2- or 3-month period. They have been found efficacious for improving bowel symptoms in several clinical trials, even in patients who have been entirely unresponsive to medical treatment. Response rates in clinical trials have ranged from 53% to 94%, and the therapeutic benefits have been shown to be well maintained at 6-, 10-, or 12-month follow-ups in different studies. This article describes the development and research on these protocols and summarizes the advantages and limitations of this fully scripted treatment approach.

    Treatment of cervical incompetence by cerclage and other methods has yet to be standardized, as its diagnosis is not uniformly accepted. Its diagnosis, particularly in the African setting, is mostly based on past obstetric history of pregnancy losses, while in developed centres; ultrasound diagnosis is increasingly being used. The mainstay of treatment in developing countries is cervical cerclage, although the indications and contraindications of this mode of treatment are not documented. Our aim was to appraise this practice in terms of patient characteristics, the diagnostic process and management at the Kenyatta National Hospital, Nairobi, Kenya. This was a descriptive retrospective study over 9 years. Predesigned questionnaires were employed to collect data on patient's socio-demographic profile, presentation, risk factors, diagnosis and management of cervical incompetence. Chi-squared test and student's t-test were used to correlate variables. A total of 199 patients were treated for cervical incompetence, with the patient mean age being 27.97. 87.4% of the patients (p = 0.02) were in the 20 to 35 years category. Most of the patients (60.1%) were of low socio-economic status. Cervical cerclage was employed in all the patients, although ultrasound investigation was not employed in 65.8% of them. Diagnosis of cervical incompetence still relies on history of previous pregnancy losses, with the standard transvaginal ultrasound relatively unemployed. There is need to intensify investigations for this condition, standardize the indications for cerclage, and diversify management to other newer modalities.

    Various therapies have been tried for psoriasis. In Japan, biologics began to be used for psoriasis treatment in January 2010. Their clinical efficacy is well known, but biologics cannot be used in all psoriasis patients for reasons such as side-effects and cost. It is necessary to evaluate the effect of long-term psoriasis treatment, but there have been no reports evaluating long-term treatment. Therefore, the outcomes of patients who had been treated at the Tokai University Hospital for more than 5 years, before biological agents were released, were examined. Three categories, classified by initial severity, changes in severity by method of treatment and background characteristics, were investigated. In conclusion, cases of long-term treatment with a combination of topical corticosteroid and topical vitamin D3 analog or oral cyclosporin were found to be effective therapies. Patients with a history of diabetes mellitus or cardiovascular disease of psoriasis were likely to be treatment resistant.

  7. Changes in soil C-isotopic composition in an agroecosystem under Free Air Carbon dioxide Enrichment (FACE) treatment during a crop rotation period.

    2005-01-01

    FACE (Free Air Carbon dioxide Enrichment) has been used since 1999 to evaluate the effects of future atmospheric CO(2) concentrations on an arable crop agroecosystem. The experiment conducted at the Institute of Agroecology at the Federal Research Centre in Braunschweig consists of a typical local crop rotation of winter barley, a cover crop, sugar beet and winter wheat. The atmospheric CO2 concentration of ambient air is about 375 ppm with a delta13C value of -7 to -9 per thousand, and 550 ppm (delta13C value = -20.2 per thousand) during daylight hours in the rings fumigated with additional CO2. Thus, the surplus C can be traced in the agricultural system. Over the course of the first experimental period (3-year crop rotation period), the C-isotopic composition and the C concentration in soil were monitored monthly. Plant samples were analysed according to the relevant developmental stages of the crop under cultivation. A 13C depletion was observed in plant parts, as well as in soil samples from the FACE rings under CO2 enrichment, indicating that labelled C has reached both respective ecosystem compartments. Albeit farming management practice (especially ploughing) leads to a mixing of 'old' and 'new' C compounds throughout all soil horizons down to the end of the ploughing layer and resulted in a heterogeneous distribution of newly formed C compounds in the soil, isotope analysis of soil C reflected where the surplus C went.

    Treatment of adolescents with growth hormone deficiency (GHD) during the transition period is a controversial issue. This paper is a contribution from the Italian community of paediatric and adult endocrinologists surveyed in a Delphi panel. The Delphi method is a structured communication technique, originally developed as a systematic, interactive forecasting method that relies on a panel of experts. The experts answer questionnaires in two or more rounds. There was substantial agreement on the definition of the problems associated with the diagnosis and treatment of adolescents with GHD in the transition period, as well as on the identification of the controversial issues which need further studies. There is general consensus on the need of re-testing all isolated idiopathic GHD after at least 30-day withdrawn from treatment, while in patients with multiple pituitary deficiency and low IGF-I levels there is generally no need to re-test. In patients with permanent or confirmed GHD, a starting low rhGH dose (0.01-0.03 mg per day) to be adjusted according to IGF-I concentrations is also widely accepted. For those continuing treatment, the optimal therapeutic schedule to obtain full somatic maturation, normalization of body composition and bone density, cardiovascular function and Quality of Life, need to be evaluated.

Mycotic cultures were taken and fungus types were detected. The laser protocol included two sessions with a one-month interval. Treatment duration was approximately 15 minutes per session and patients were observed over a 3-month time period. Laser fluencies of 14 J/cm2 were applied at 9 billionths of a second pulse duration and at 5 Hz frequency. Follow-up was performed at 3 months with mycological cultures. Before and after digital photographs were taken. Adverse effects were recorded and all participants completed “self-evaluation questionnaires” rating their level of satisfaction. All subjects were well satisfied with the treatments, there were no noticeable side effects, and no significant differences were found treating men versus women. At the 3-month follow-up 95.42% of the patients were laboratory mycologically cured of fungal infection. This clinical study demonstrates that fungal nail infections can be effectively and safely treated with Q-Switched Nd:YAG 1064 nm/532 nm laser. It can also be combined with systemic oral antifungals providing more limited treatment time. PMID:24396343

    Episodic spontaneous hypothermia is an infrequent disorder, with unknown pathogenic mechanisms. A systemic cause or underlying brain lesion has not been found for the disease. We report four new patients, 3-9 years old, with episodic hypothermia lower than 35 degrees C, marked facial pallor, and absent shivering. The episodes could last a few hours or four days, and recurred once a week or every 2-3 months. Two patients also demonstrated bradycardia, mild hypertension, and somnolence during the events; in one of them, profuse sweating was also a feature, and all four presented with either headache, a periodic childhood syndrome, or both (recurrent abdominal pain, cyclic vomiting, or vertigo). Three patients reported a family history of migraine. Neurologic examination, endocrine function, and imaging studies were normal. Migraine prophylactic therapy was of moderate efficacy. Spontaneous resolution was observed in one patient. The clinical characteristics of the syndrome allow for its inclusion as a childhood periodic syndrome related to migraine. PMID:12849886

    The present aimed to develop a hormonal therapy based on the insertion of a progesterone (P4) insert (PI) during 10 d plus an estradiol injection (E2) at PI removal before the onset of breeding of beef heifers. In Exp. 1, the plasma P4 profile of prepubertal heifers showed that the insertion of a PI or 24 d previously used P4 insert (UPI) sustained plasma P4 above 1 ng/mL for at least the first 7 d of the treatment. In Exp. 2 there was no positive effect of additional estradiol benzoate (EB) administered at the insertion of UPI on the proportion of heifers with a corpus luteum (CL/Treated) 30 d after UPI removal [UPI + EB = 85.3%(a) (n = 134); EB + UPI + EB = 80.8%(a) (n = 125)]; however, both were greater (P < 0.0001) than the Control group [60.3%(b) (n = 129)]. In Exp. 3, a positive effect (P=0.01) of UPI treatment and both E2 supplementations [EB and estradiol cypionate (EC); P = 0.10] at the UPI removal was observed on CL/Treated [Control = 42.5%(b) (n = 94); UPI = 58.5%(a) (n= 130); UPI + EB = 64.0%(a) (n = 128); UPI + EC = 67.2%(a) (n = 128)]. However, greater pregnancy per treated heifer (P/Treated) following artificial insemination (AI) upon estrus detection was achieved when EC was applied [Control = 20.2%(b); UPI = 29.2%(ab); UPI + EB = 26.6%(b); UPI + EC = 36.7%(a)]. In Exp. 4, the treatment prior to the timed AI (TAI) tended to improve pregnancy per TAI [P/AI; Control 43.6% (n = 298) vs. UPI+EC 51.9% (n = 342); P = 0.08], but increased P/Treated [26.5% vs. 43.3%; P < 0.001]. Thus, UPI + EC treatment were efficient in increasing the CL/Treated, tended to improve the P/AI and consequently enhanced P/Treated of zebu beef heifers.

    Very interesting results of several long-term studies concerning the treatment of hypertension were recently presented at the 18th "Journées de l'Hypertension" conference. Two of them are particularly interesting as, to our knowledge, they are the first studies designed to evaluate the use of fixed very low dose ACE inhibitor/diuretic bitherapy as first-line treatment for systolodiastolic hypertension and isolated systolic hypertension, over a long follow-up period. Both studies included hypertensive patients over the age of 65, and the only option left to the investigators was to adapt the dosage in the case of insufficient blood pressure control (suspine DBP > 90 mmHg). In particular, the results in the overall population show that 80% of patients "controlled" at 3 months, subsequently remained controlled throughout the study period (total of 15 months). The results obtained in isolated systolic hypertension were of the same order of magnitude. The results observed with this fixed very low dose ACE inhibitor/diuretic bitherapy appear very promising in terms of compliance with treatment and long-term blood pressure control, compared to those obtained with any other antihypertensive drugs indicated as first-line treatment of hypertension.

    This study was performed to evaluate the effects of a patient-centered, tablet computer-based self-monitoring system for chronic disease care. A 3-month randomized controlled pilot trial was conducted to compare the use of a computer-based self-monitoring system in disease self-care (intervention group; n = 33) with a conventional self-monitoring method (control group; n = 30) in patients with type 2 diabetes mellitus and/or hypertension. The system was equipped with a 2-in-1 blood glucose and blood pressure monitor, a reminder feature, and video-based educational materials for the care of the two chronic diseases. The control patients were given only the 2-in-1 monitor for self-monitoring. The outcomes reported here included the glycated hemoglobin (HbA1c) level, fasting blood glucose level, systolic blood pressure, diastolic blood pressure, chronic disease knowledge, and frequency of self-monitoring. The data were collected at baseline and at 1-, 2-, and 3-month follow-up visits. The patients in the intervention group had a significant decrease in mean systolic blood pressure from baseline to 1 month (p < 0.001) and from baseline to 3 months (p = 0.043) compared with the control group. Significant improvements in the mean diastolic blood pressure were seen in the intervention group compared with the control group after 1 month (p < 0.001) and after 2 months (p = 0.028), but the change was not significant after 3 months. No significant differences were observed between the groups in the fasting blood glucose level, the HbA1c level, or chronic disease knowledge. The frequency of self-monitoring of blood glucose level and blood pressure was similar in both groups. The performances of the tablet computer-assisted and conventional disease self-monitoring appear to be useful to support/maintain blood pressure and diabetes control.

Those whose baseline screening indicated the need for a brief instead of a more intensive intervention, and those currently engaged in drug treatment at the 3-month follow-up, were generally more likely to stop or decrease their drug use/misuse. Conclusions The BI employed in this study did not reduce drug use and misuse or increase treatment utilization more than the control condition over a 3-month period. Future research should help determine what role, if any, BIs should play in affecting drug use and misuse among ED patients. PMID:26375468

    To reduce HIV incidence, prevention programs centered on the use of antiretrovirals require scaling-up HIV testing and counseling (HTC). Home-based HTC services (HBHTC) increase HTC coverage, but HBHTC has only been evaluated during one-off campaigns. Two years after an initial HBHTC campaign (“round 1”), we conducted another HBHTC campaign (“round 2”) in Likoma (Malawi). HBHTC participation increased during round 2 among women (from 74% to 83%, p<0.01). New HBHTC clients were recruited, especially at ages 25 and older. Only 6.9% of women but 15.9% of men remained unreached by HBHTC after round 2. HIV prevalence during round 2 was low among clients who were HIV-negative during round 1 (0.7%), but high among women who first tested during round 2 (42.8%). The costs per newly diagnosed infection increased significantly during round 2. Periodically conducting HBHTC campaigns can further increase HTC, but supplementary interventions to enroll individuals not reached by HBHTC are needed. PMID:23180155

  18. The classical electrostatic periodic table, capacitance of few electron dielectric spheres and a novel treatment of one- and two-electron finite quantum wells

    NASA Astrophysics Data System (ADS)

    Lafave, Tim, Jr.

    The centerpiece of this dissertation is the discovery of the classical electrostatic periodic table of elements through non-linear ground state energies coincident with atomic shell-filling resulting from symmetry properties of discrete electrons constrained by a spherically-symmetric system. The time-independent electrostatic equilibrium configuration of few electrons confined to a large classical dielectric sphere is obtained by minimization of the total interaction energy. The interactions model yields more than twice the energy predicted by the classical Gauss model. Each N-electron system is proposed as a unique phase characterized by its symmetry properties. A new mono-phasic capacitance definition of dielectric spheres is derived from the fundamental relation Q=CV. Large differences from the Gauss model are obtained for few-electron systems, but convergence is found in the metallic limit. Of particular significance is the means by which symmetry-dependent properties of atomic-scale devices may be exploited by controlling the internal architecture of charge distributions. This work will be useful to modeling of many-electron chemical and biological systems, such as macromolecules, owing largely to symmetry differences between the Gauss model and the interactions model. The foundation upon which all Nature rests is the symmetry of fundamental particles.

    The objective of the study was to evaluate efficacy and tolerance of tanakan during treatment of neurosensory hearing loss and subjective tinnitis supposedly of vascular etiology. The secondary purpose was to analyse late results of 3 month courses of therapy and changes in the clinical course of the disease during treatment and within 6 months after its termination. Tanakan was first given at a dose of 40 mg thrice daily for 90 days. Results of the treatment were estimated on days 90, 180, and 240. The second course (40 mg thrice daily for 90 days) was initiated 180 days after the end of the first one. The final outcome was evaluated on day 360. It was shown that monotherapy with tanakan effectively improved the hearing function and had the most pronounced beneficial effect on subjective tinnitus. Results of the treatment remained stable throughout the entire observation period (12 months). PMID:19491797

    Venous ulcer of the lower extremity is a common vascular condition and is associated with decreased quality of life, reduced mobility, and social isolation. Treatment of chronic venous ulcer (CVU) includes compression therapy, debridement of the ulcer when necessary, and wound care. Collagen and antimicrobial dressings can improve the proportion of ulcers healed compared with compression alone. Acellular skin equivalents are not superior to compression, but cellular human skin equivalents can promote more rapid healing, particularly in patients with longstanding ulcers. Current vascular surgical practice is to eliminate documented reflux or obstruction in patients with CVU that have failed a 3-month period of compression dressing, debridement, and local wound care. We found that surgical treatment of the superficial venous system can decrease the time to healing of CVUs compared with compression therapy alone, but does not increase the proportion of ulcers healed.

    The Northern Territory Alcohol Mandatory Treatment Act 2013 (AMT Act) permits mandatory residential alcohol rehabilitation for up to 3 months. International guidelines and human rights law confirm that mandatory rehabilitation should only be used for short periods. Evidence concerning the efficacy of long-term mandatory alcohol rehabilitation is lacking, and minimal data concerning the efficacy of the scheme have been released. Specific legal issues also arise concerning the AMT Act, including its potentially discriminatory application to Aboriginal and Torres Strait Islander peoples. The program only permits referral by police, despite the fact that it is ostensibly a medical intervention. Use of a treatment as a method of effectively solving a public intoxication problem is highly dubious, and should be of concern to the medical community. Given that more cost-effective and proven measures exist to combat alcohol dependence, the utility of the AMT Act is questionable.

    Background. Vaginal infections are common, frequently recur, and may increase women's risk for sexually transmitted infections (STIs). We tested the efficacy of a novel regimen to prevent recurrent vaginal infections. Methods. Human immunodeficiency virus (HIV)–negative women 18–45 years old with 1 or more vaginal infections, including bacterial vaginosis (BV), vulvovaginal candidiasis (VVC), or Trichomonas vaginalis (TV), were randomly assigned to receive vaginal suppositories containing metronidazole 750 mg plus miconazole 200 mg or matching placebo for 5 consecutive nights each month for 12 months. Primary endpoints, evaluated every 2 months, were BV (Gram stain) and VVC (positive wet mount and culture). Results. Participants (N = 234) were randomly assigned to the intervention (N = 118) or placebo (N = 116) arm. Two hundred seventeen (93%) women completed an end-of-study evaluation. The intervention reduced the proportion of visits with BV compared to placebo (21.2% vs 32.5%; relative risk [RR] 0.65, 95% confidence interval [CI] .48–.87). In contrast, the proportion of visits with VVC was similar in the intervention (10.4%) versus placebo (11.3%) arms (RR 0.92, 95% CI .62–1.37). Conclusions. Monthly treatment with intravaginal metronidazole plus miconazole reduced the proportion of visits with BV during 12 months of follow-up. Further study will be important to determine whether this intervention can reduce women's risk of STIs. PMID:25526757

    A comparative evaluation of low-level laser and CO(2) laser therapies was performed, for the treatment of oral lichen planus (OLP). In a randomized open clinical trial, 28 patients with 57 lesions were randomly assigned to two groups. One group received CO(2) laser therapy, the other received low-level laser therapy (LLLT) for 5 sessions every other day. Participants were examined before the treatment, after 2 weeks, and at 1, 2 and 3 months, to assess the changes in sign and symptom scores. Improvements in size of lesions, in pain and clinical response scores were achieved in both groups. After 3 months, clinical response showed 100% and 85% partial to complete improvement in LLLT and CO(2) laser surgery, respectively. This demonstrates a quick and pronounced beneficial effect in controlling symptoms related to OLP. Both methods may be effective in the treatment of OLP, and can be used as alternative therapy alongside standard treatment modalities. The present study showed that LLLT displayed better results than CO(2) laser therapy as alternative or additional therapy, but further investigations in comparison with standard treatment modalities with a prolonged follow-up period will be necessary to confirm the efficacy of laser therapy in the treatment of OLP.

    A 27-year-old female with a type 2 hydatid cystic lesion in the liver according to the Gharbi classification (CE 3A according to the WHO classification) was referred for percutaneous treatment after albendazole treatment for 1 year. A catheterization technique was performed but hypertonic saline and alcohol were not given into the cavity due to cystobiliary leakage. During the 4-month follow-up period, sequential cavitography revealed biliary fistula, and bile-stained drainage had not been ceased despite the sphincterotomy, nasobiliary drainage catheter, and plastic stent. Since the patient refused to surgery, we embolized the biliary fistula using N-butyl 2-cyanoacrylate for the first time in the literature. At the 3-month follow-up, the patient's course was uneventful and ultrasound, multidetector-row CT, and MRI examinations revealed no collection in or adjacent to the cavity.

    Treatment of keloids (K) and hypertrophic scars (HTS) is challenging. A few case reports reported good results in HTS treated by fractional CO2 laser. The aim of the present study was the assessment of the clinical response as well as histological changes in K and HTS treated by fractional CO2 laser and the role of matrix metalloproteinase 9 (MMP9) in the response. A randomized half of the scar was treated by fractional CO2 laser in 30 patients (18 K, 12 HTS) for a total of four sessions 6 weeks apart. Vancouver scar score (VSS) was done before and 1, 3, and 6 months after the last laser session by a blinded observer. Biopsies taken from normal skin, untreated scar, and treated scar tissue 1 and 3 months after the laser sessions were stained by HX & E for histological changes and Masson trichrome for collagen fiber arrangement. Immunohistochemical staining for MMP9 was done in before and 1 month after samples. Quantitative morphometric analysis was done for collagen and MMP9 by image analyzer. Nineteen patients completed the 6-month follow-up period (12 K, 7 HTS). VSS score was significantly lower in the treated compared to untreated areas after 3 and 6 months in both K and HTS but was mainly due to improved pliability of the scar. Histologically, dense inflammatory infiltrate and increased vascularity was apparent 1 month after laser sessions and disappeared at 3 months. Thinner better organized collagen bundle could be seen in 3 months after samples. MMP9 was significantly increased in after treatment samples but without significant correlation with VSS. Fractional CO2 resurfacing is safe but affects mainly pliability of K and HTS with collagen remodeling apparent 3 months after therapy. MMP9 may play a role in mechanism of action of CO2 laser in K and HTS.

    Under current conditions, high-technology herbal preparations take an important place in the complex treatment of patients with urolithiasis. Canephron N (Bionorica, Germany) is one of these herbal drugs widely used in urology. The article presents the results of comprehensive evaluation of the effectiveness of the canephron N in patients with urolithiasis, who undergone extracorporeal shockwave lithotripsy, in the postoperative period and in the period of early (up to 3 months) metaphylaxis. It is shown that the use of the drug in complex treatment of patients with urolithiasis contributes to more rapid discharge of fragments of stones and effective improvement of renal function after removal of stones. The use of canephron N has great potential in the complex metaphylaxis of urolithiasis.

    Purpose This study aims to evaluate and compare the efficacy of exogenous melatonin associated with desmopressin (dDAVP) and dietary recommendations. Methods A total of 189 patients were enrolled from the Service of Pediatrics, Campus Bio-Medico University Hospital of Rome, from January 2013 to June 2015. Of the 189 original patients, 153 children, aged between 5 and 14 years (mean age, 8.7 years) were included in the study. After clinical evaluation and a 3-month period of observation without treatment, children were assigned to receive treatment in one of 3 groups: group 1, dDAVP at a dose of 120 mcg a day (Minirin); group 2, dDAVP at a dose of 120 mcg and dietary recommendations; or group 3, dDAVP at a dose of 120 mcg, dietary recommendations, and melatonin at a dose of 1 mg a day (Melamil plus). Each patient was treated for 3 months. Results After the 3 months of therapy, a desiderable response was achieved in 30 of 51 patients (58.82%) treated with dDAVP, 35 of 53 patients (66.04%) treated with dDAVP and dietary recommendations, and 35 of 49 patients (71.43%) treated with dDAVP, dietary recommendations, and melatonin. Conclusions Although not statistically significant, the results show that the association between dDAVP treatment with dietary recommendations and melatonin could be considered a safe and effective treatment of NE. Considering that the statistically insignificant results might be due to the small sample size, the study will be continued to increase the number of subjects. PMID:27706008

    Objectives: To evaluate the effectiveness of topical 5-aminolevulinic acid (ALA)- medicated photodynamic therapy (ALA PDT) for the treatment of moderate to severe acne vulgaris. Methods: Sixteen Chinese patients with moderate to severe facial acne were treated with 1-3 courses of ALA PDT. ALA cream (3%) was freshly prepared and applied to acne lesions for 3-4 h. The lesions were irradiated by a 635 nm diode laser at dose levels of 60 - 80 J/cm2 at 100 mW/cm2. Clinical assessments were conducted before and after treatment up to 3 months. Results: All patents showed response to ALA PDT. Complete clearance was seen in 10 patients (62.5%) and partial clearance in 6 patients (37.5%). One case showed recurrence after complete clearance at 2 months and another two showed recurrence after complete clearance at 3 months. However, the number of new lesions were significantly reduced. Adverse effects were minimal. Conclusions: The results of this preliminary clinical study is encouraging. ALA PDT is a simple, safe and useful therapeutic option for the treatment of moderate to severe acne. Further studies to evaluate the treatment with a larger number of patients and for a longer period of follow-up are needed.

    The present study aimed to investigate the efficacy of repetitive cathodal direct current stimulation (rctDCS) over the visual cortex as a prophylactic treatment in patients with menstrual migraine. 20 female patients were recruited in this double-blind, placebo-controlled study and were assigned to receive either cathodal or sham stimulation. Over 3 menstrual cycles, tDCS with 2mA intensity and 20 min duration was applied to the visual cortex of the patients, in 5 consecutive sessions 1-5 days prior to the first day of their menstruation. The primary endpoint of the study was the frequency of the migraine attacks at the end of the treatment period, however, additional parameters, such as the number of migraine related days and the intensity of pain were also recorded 3 months before, during and 3 months post-treatment. Visual cortex excitability was determined by measuring the phosphene thresholds (PTs) using single pulse transcranial magnetic stimulation (TMS) over the visual cortex. Sixteen patients completed the study. A significant decrease in the number of migraine attacks (p=0.04) was found in the cathodal group compared to baseline but not compared to sham (p=0.053). In parallel the PTs increased significantly in this group, compared to the sham group (p<0.05). Our results indicate that prophylactic treatment with rctDCS over the visual cortex might be able to decrease the number of attacks in patients with menstrual migraine, probably by modifying cortical excitability.

    Substance use disorders, including cannabis use disorders and associated negative consequences, are best considered chronic and in need of continuing care. In contrast, most treatment efficacy studies evaluate a fixed number of intervention sessions at a single point in time. The present study evaluated the efficacy of posttreatment Maintenance Check-Ups (MCUs) in maintaining and improving outcomes following nine sessions of motivational enhancement treatment/cognitive behavioral treatment (MET/CBT). Adults dependent on cannabis (n = 74) were randomly assigned to the MCU or a No Check-Up (NCU) condition and followed up at 3-and 9-months. MCU sessions occurred 1 and 4 months following the completion of the base treatment. Additional MET/CBT sessions were available to participants throughout the follow-up period. The MCUs specifically encouraged treatment re-entry for those showing ongoing signs of disorder. Participants in the MCU condition reported significantly greater abstinent rates at both follow-ups and were using on fewer days at the 3-month but not the 9-month follow-up. Contrary to hypotheses, MCU participants did not attend more additional treatment and differences in rates of cannabis use emerged prior to the first MCU session. Future research with longer follow-up periods and longer monitoring of outcomes is needed to fully evaluate the utility of MCUs or other forms of continuing care. PMID:25922136

    Bevacizumab is a humanized monoclonal antibody that inhibits vascular endothelial growth factor, and it has been found to increase both progression-free survival and overall survival when it is combined with chemotherapeutic agents in the first-line and subsequent treatment of metastatic colorectal carcinoma. The objective of this study was to show the efficacy of maintenance treatment with capecitabine plus bevacizumab in patients with metastatic colorectal cancer who responded to treatment with FOLFIRI plus bevacizumab. The study included patients with metastatic colorectal cancer who received FOLFIRI plus bevacizumab as a first-line treatment. Patients who had objective response with FOLFIRI plus bevacizumab treatment after an average period of 6 months received a maintenance treatment with capecitabine plus bevacizumab (capecitabine 2 x 1000 mg/m2, 1 - 14 days, every 21 days, bevacizumab 7.5 mg/m2, every 21 days) until disease progression or toxicity. The time to progression on bevacizumab treatment was evaluated. A total of 29 patients (15 male, 14 female) were included. The mean age was 62 years. The mean number of cycles for maintenance treatment with capecitabine plus bevacizumab was 12. The median PFS was 16 ± 3 months, and OS was 42 ± 11 months. PFS and OS were remarkably higher in patients with a complete or near complete response to induction treatment. Fourteen patients (48%) experienced hand-foot syndrome associated with capecitabine plus bevacizumab treatment, without any severe toxicity. Inselected patients with metastatic colorectal carcinoma who had a remarkable objective response to FOLFIRI plus bevacizumab treatment, a maintenance treatment with capecitabine plus bevacizumab following FOLFIRI plus bevacizumab until disease progression may be a suitable, effective and tolerable regimen, which requires further studies.

    Fresh leachate, generated in municipal solid waste incineration (MSWI) plants, contains various pollutants with extremely high strength organics, which usually requires expensive and complex treatment processes. This study investigated the feasibility of blending treatment of MSWI leachate with municipal wastewater. Fresh MSWI leachate was pretreated by coagulation-flocculation with FeCl3 2 g/L and CaO 25 g/L, plate-and-frame filter press, followed by ammonia stripping at pH above 12. After that, blending treatment was carried out in a full-scale municipal wastewater treatment plant (WWTP) for approximately 3 months. Different operational modes consisting of different pretreated leachate and methanol addition levels were tested, and their performances were evaluated. Results showed that throughout the experimental period, monitored parameters in the WWTP effluent, including COD (<60 mg/L), BOD5 (<20 mg/L), ammonium (<8 mg/L), phosphorus (<1.5 mg/L) and heavy metals, generally complied with the Chinese sewage discharged standard. Under the experimental conditions, a certain amount of methanol was needed to fulfill TN removal. An estimation of the operation cost revealed that the expenditure of blending treatment was much lower than the total costs of respective treatment of MSWI leachate and municipal wastewater. The outcomes indicated that blending treatment could not only improve the treatability of the MSWI leachate, but also reduce the treatment cost of the two different wastewaters.

    Infections with gastrointestinal parasitic helminthes were historically surveyed from the Jomon period to the end of the Edo period in Japan. The parasitic helminthes whose eggs or symptoms were shown in the remains and bibliographies are the roundworm, whipworm, liver fluke, Yokogawa's fluke and the cestode, Diphyllobothrium sp. The first two are soil-transmitted nematodes and the other three parasitic helminths are those with which people are infected following eating raw fish. The infection routes provide valuable information on the environments, life-style and customs in those days. The eggs of the soil-transmitted parasites have the thick shells resistant to the environments. Humans are infected with the parasites after the eggs are orally ingested with soil, dust, vegetables grown with night soil or manure. When the custom of the night soil was started in the history of Japan was discussed with this infection route. In ancient times, feces are thought to have been discarded. In the Medieval Period, they were started to be used as a fertilizer. No mature types of manure were used until the modern times (already in the Edo period). To our idea, no recoveries of eggs of hookworms causing severe anemia do not necessarily mean that people were not infected with the parasites in those days because the eggs are covered with thin shells liable to rupture. The latter fact of the eggs of the platihelminths, C. sinensis, M. yokogawai and D. latum has something to do with Japanese traditional eating customs, unequivocally demonstrating that they ate raw fish from the Nara Period, at latest, until today. Whether eggs of the cestode (D. latum) are found in Jomon remains, Momijiyama Iseki, Hokkaido should be investigated. If no eggs of the cestode are found in their toilet site or elsewhere, it could be concluded that they did not have the custom of eating raw salmon. Such a conclusion would be itself a new fact. One of the effective treatments for the cestode (D. latum

    Background: Platelet-rich plasma (PRP) has shown remarkable beneficial effects without any major adverse reactions in the treatment of androgenic alopecia. The growth factors in activated autologous PRP induce the proliferation of dermal papilla cells. Objectives: The objective was to investigate the clinical efficacy of PRP in treatment of androgenic alopecia. Materials and Methods: Ten patients were given autologous PRP injections on the affected area of alopecia over a period of 3 months at interval of 2-3 weeks and results were assessed. Results: Three months after the treatment, the patients presented clinical improvement in the hair counts, hair thickness, hair root strength, and overall alopecia. Conclusion: PRP appears to be a cheap, effective, and promising therapy for androgenic alopecia with no major adverse effects. PMID:26420936

    A field pilot study of a steam injection method for the treatment of pentachlorophenol (PCP)-contaminated soil and groundwater has shown potential advantages over the traditional pump-and-treatment method. Low-pressure steam was injected 10 m below the ground surface. The ground water temperature was raised to 118 degrees C over a period of 3 months. Five soil and groundwater sampling events were performed during the pilot test. Results of sample analysis showed that the PCP concentrations in deep aquifer soil decreased dramatically whereas those in shallow aquifer soil increased. It was concluded that raising the groundwater temperature caused PCP in deep aquifer soil to be desorbed, and as the hot, deep groundwater circulated upward, it brought the desorbed PCP to the shallow aquifer. By using steam injection, PCP can be desorbed from soil and moved upward to the ground surface so that it can be removed more easily through pump-and-treatment.

    Altered adult hippocampal neurogenesis (AN) plays a role in the etiopathology of Alzheimer's disease (AD), a disorder characterized by a progressive loss of memory and spatial orientation impairment. Diabetes is shown to be one risk factor for the development of the sporadic form of AD (sAD), which affects >95% of AD patients. Streptozotocin intracerebroventricularily (STZ icv) treated rats, which develop an insulin-resistant brain state and learning and memory deficits preceding amyloid beta and tau pathology, may act as an appropriate animal model for sAD. The goal of our quantitative immunohistochemistry study was to compare short-term (1 month) and long-term (3 months) effects of STZ icv treatment on different AN stages. Applying MCM2 antibodies we quantified cell (e.g. stem cell) proliferation, by the use of NeuroD and DCX antibodies we analyzed immature neurons. BrdU incorporation with approximately 27 days of survival before sacrifice allowed us to quantify and identify surviving newborn cells. Performing co-localization studies with antibodies detecting BrdU and cell-type specific markers we could confirm that STZ treatment does not affect the differentiation fate of newly generated cells. Whereas STZ icv treatment does not seem to considerably influence cell proliferation over a shortterm period (1 month), in the long-term (3 months) it significantly decreased generation of immature and mature neurons. This reduction seen after 3 months was specific for the septal hippocampus, discussed to be important for spatial learning. Moreover, AN changes display the same timeline as the development of amyloid beta pathology in this animal model of sAD.

    Postmenopausal hyperhidrosis is a form of secondary hyperhidrosis, and hormone-replacement therapy is a commonly used therapeutic option. However, some women do not benefit from this treatment, and oral anticholinergics are a logical alternative for reducing generalized sweating in these patients. Twenty-one patients were medicated with 5 or 10 mg of oxybutynin per day. After a 3-month follow-up period, efficacy was assessed with the Hyperhidrosis Disease Severity Scale (HDSS) and the Dermatology Life Quality Index (DLQI) was used to assess the improvement in patients' quality of life. The HDSS score was 3.2 +/- 0.4 (mean +/- SD) before medication and 1.9 +/- 0.4 after 3 months. The baseline DLQI score of 8.4 +/- 1.0 was reduced to 4.4 +/- 0.9. No serious side-effects or adverse events resulted from treatment. Oxybutynin was a well-tolerated, effective, and safe method for treating postmenopausal sweating. However, long-term medication and the limited effects of the treatment were disadvantages. PMID:20526549

  5. Socio-cultural determinants of timely and delayed treatment of Buruli ulcer: Implications for disease control

    Introduction Public health programmes recommend timely medical treatment for Buruli ulcer (BU) infection to prevent pre-ulcer conditions from progressing to ulcers, to minimise surgery, disabilities and the socio-economic impact of BU. Clarifying the role of socio-cultural determinants of timely medical treatment may assist in guiding public health programmes to improve treatment outcomes. This study clarified the role of socio-cultural determinants and health system factors affecting timely medical treatment for BU in an endemic area in Ghana. Methods A semi-structured explanatory model interview based on the explanatory model interview catalogue (EMIC) was administered to 178 BU-affected persons. Based on research evidence, respondents were classified as timely treatment (use of medical treatment 3 months from awareness of disease) and delayed treatment (medical treatment 3 months after onset of disease and failure to use medical treatment). The outcome variable, timely treatment was analysed with cultural epidemiological variables for categories of distress, perceived causes of BU, outside-help and reasons for medical treatment in logistic regression models. The median time for the onset of symptoms to treatment was computed in days. Qualitative phenomenological analysis of respondents’ narratives clarified the meaning, context and dynamic features of the relationship of explanatory variables with timely medical treatment. Results The median time for initiating treatment was 25 days for pre-ulcers, and 204 days for ulcers. Income loss and use of herbalists showed significantly negative associations with timely treatment. Respondents’ use of herbalists was often motivated by the desire for quick recovery in order to continue with work and because herbalists were relatives and easily accessible. However, drinking unclean water was significantly associated with timely treatment and access to health services encouraged timely treatment (OR 8.5, p = 0

    The major branch of the Seine river from the confluence with the Marne river to the entrance of the estuary is deeply affected by the release of wastewater from the huge Paris agglomeration. In the first years of 2000, the largest part of the effluents were still discharged at the Seine-Aval (Achères) treatment plant with only a standard, low residence time, activated sludge treatment, thus releasing a high ammonium load. NH4 concentration as high as 7 mgN/l were frequently observed downstream from Paris agglomeration. Cébron et al. (2003, 2005) and Garnier et al. 2007 described in details how this massive reduced nitrogen concentrations triggered the growth of nitrifying bacteria, already present in the upstream Seine and Marne rivers, but also brought in large amount by the effluents of the wastewater treatment plant themselves. The decrease of ammonium concentration was slow, however, and was only completed 200 km downstream, in the upper estuarine area, where it causes a severe oxygen deficiency. Since 2007, important changes occurred in the treatment of nitrogen in the Parisian wastewater purification plants. In 2007, the Seine-Aval plant treated up to 90% of the ammonium contained in wastewater through nitrification, and 30% of the total supply of nitrates is treated by denitrification. These modifications have of course favorably affected the water quality of the Seine river: ammonium concentrations are reduced by a factor of 5 and the area of oxygen depletion in the upstream estuary is no more observed. However, nitrites, still released in the effluents, are a matter of concern for the water quality of the Seine downstream from Paris. Using measurements of potential microbial activities carried out with the same experimental protocol for the 2000-2003 and 2012-2013 periods, we here examine and model the dynamics of ammonium oxidizing and nitrite oxidizing microbial populations before and after the implementation of nitrification treatment of Paris

    Purpose: This study was designed to assess the rate of complications and clinical failure at 3 and 12 months after percutaneous treatment of vascular malformations in children. Furthermore, we describe patient satisfaction of treatment results during 5 years of follow-up. Methods: In a retrospective cohort study, we evaluated 26 patients younger than aged 19 years who were treated for symptomatic vascular malformations. Data on treatment outcomes and patient satisfactions were obtained with a precoded structured questionnaire. Patient files and imaging data were retrieved to obtain information regarding the vascular malformations and treatment. Clinical success was defined as disappearance or partial improvement of the complaints. Patient satisfaction was declared whenever patients answered in the questionnaire that they were satisfied with the treatment results. Results: Of 26 eligible patients, we included 23 (88%). The mean follow-up was 36 (range, 15-127) months. Posttreatment, 87% (20/23; 95% confidence interval (CI), 66-97%) of patients reported clinical success at 3 months. At 1, 2, 3, 4, and 5 years of follow-up this percentage was 74%, 59%, 59%, 59%, and 59%, respectively. Eleven (48%, 95% CI 27-69%) patients had experienced complications and 22% (95% CI 7-44%) had major complications, of which 5 had required additional treatment. In all, 83% (19/23) of the patients reported satisfaction with the treatment. Conclusions: Percutaneous treatment of vascular malformations improved clinical symptoms in 87% of the patients at 3 months and were sustainable for half of all patients during a 5-year follow-up period. However, major complications were seen in 22%.

    Purpose To determine the safety of engaging HIV-positive (HIV+) adolescents in a Family Centered Advance Care (FACE) planning intervention. Patients and methods We conducted a 2-armed, randomized controlled clinical trial in 2 hospital-based outpatient clinics from 2006–2008 with HIV+ adolescents and their surrogates (n = 76). Three 60–90 minutes sessions were conducted weekly. FACE intervention groups received: Lyon FCACP Survey©, the Respecting Choices® interview, and completion of The Five Wishes©. The Healthy Living Control (HLC) received: Developmental History, Healthy Tips, Future Planning (vocational, school or vocational rehabilitation). Three-month post-intervention outcomes were: completion of advance directive (Five Wishes©); psychological adjustment (Beck Depression, Anxiety Inventories); quality of life (PedsQL™); and HIV symptoms (General Health Self-Assessment). Results Adolescents had a mean age, 16 years; 40% male; 92% African-American; 68% with perinatally acquired HIV, 29% had AIDS diagnosis. FACE participants completed advance directives more than controls, using time matched comparison (P < 0.001). Neither anxiety, nor depression, increased at clinically or statistically significant levels post-intervention. FACE adolescents maintained quality of life. FACE families perceived their adolescents as worsening in their school (P = 0.018) and emotional (P = 0.029) quality of life at 3 months, compared with controls. Conclusions Participating in advance care planning did not unduly distress HIV+ adolescents. PMID:22096382

    2011-01-01

    Cortical circuits in the brain are refined by experience during critical periods early in postnatal life. Critical periods are regulated by the balance of excitatory and inhibitory (E/I) neurotransmission in the brain during development. There is now increasing evidence of E/I imbalance in autism, a complex genetic neurodevelopmental disorder diagnosed by abnormal socialization, impaired communication, and repetitive behaviors or restricted interests. The underlying cause is still largely unknown and there is no fully effective treatment or cure. We propose that alteration of the expression and/or timing of critical period circuit refinement in primary sensory brain areas may significantly contribute to autistic phenotypes, including cognitive and behavioral impairments. Dissection of the cellular and molecular mechanisms governing well-established critical periods represents a powerful tool to identify new potential therapeutic targets to restore normal plasticity and function in affected neuronal circuits.

    Rosmarinus officinalis L. is a medicinal plant with diverse activities including enhancement microcapillary perfusion. The present study aimed to investigate the clinical efficacy of rosemary oil in the treatment of androgenetic alopecia (AGA) and compare its effects with minoxidil 2%. Patients with AGA were randomly assigned to rosemary oil (n = 50) or minoxidil 2% (n = 50) for a period of 6 months. After a baseline visit, patients returned to the clinic for efficacy and safety evaluations every 3 months. A standardized professional microphotographic assessment of each volunteer was taken at the initial interview and after 3 and 6 months of the trial. No significant change was observed in the mean hair count at the 3-month endpoint, neither in the rosemary nor in the minoxidil group (P > .05). In contrast, both groups experienced a significant increase in hair count at the 6-month endpoint compared with the baseline and 3-month endpoint (P < .05). No significant difference was found between the study groups regarding hair count either at month 3 or month 6 (> .05). The frequencies of dry hair, greasy hair, and dandruff were not found to be significantly different from baseline at either month 3 or month 6 trial in the groups (P > .05). The frequency of scalp itching at the 3- and 6-month trial points was significantly higher compared with baseline in both groups (P < .05). Scalp itching, however, was more frequent in the minoxidil group at both assessed endpoints (P < .05). The findings of the present trial provided evidence with respect to the efficacy of rosemary oil in the treatment of AGA.

    Objectives. To evaluate and compare the efficacy, safety, hydrating properties, and tolerability of 10% lactic acid (LA) and 5% salicylic acid (SA) in the therapy of keratosis pilaris (KP). Material and Method. Patients with KP were randomized for treatment with either 10% LA or 5% SA creams being applied twice daily for 3 months. The patients were clinically assessed at baseline and after 4, 8, and 12 weeks of treatment and 4 weeks after treatment. The functional properties of the stratum corneum (SC) were determined before treatment, 12 weeks, and follow-up phase by high-frequency conductance and transepidermal water loss (TEWL). Results. At the end of the trial, the mean reduction of the lesions from baseline was statistically significant for 10% LA (66%) and 5% SA (52%). During the treatment, higher conductance values were found on both group and this improvement was maintained until the follow up period. No significant differences in transepidermal water loss were observed after treatment. The adverse effects were limited to mild irritation localized on the skin without systemic side effect. Conclusion. The study demonstrated that 10% LA and 5% SA are beneficial to treat KP with the significantly clearance and marked improvement as by instrumental evaluation. PMID:25802513

    Detrended fluctuation analysis (DFA) is used to examine long-range dependence in variations and volatilities of American treasury bills (TB) during periods of low and high movements in TB rates. Volatility series are estimated by generalized autoregressive conditional heteroskedasticity (GARCH) model under Gaussian, Student, and the generalized error distribution (GED) assumptions. The DFA-based Hurst exponents from 3-month, 6-month, and 1-year TB data indicates that in general the dynamics of the TB variations process is characterized by persistence during stable time period (before 2008 international financial crisis) and anti-persistence during unstable time period (post-2008 international financial crisis). For volatility series, it is found that; for stable period; 3-month volatility process is more likely random, 6-month volatility process is anti-persistent, and 1-year volatility process is persistent. For unstable period, estimation results show that the generating process is persistent for all maturities and for all distributional assumptions.

    Evidence for effective treatment for behavioral problems continues to grow, yet evidence about the effective mechanisms underlying those interventions has lagged behind. The Stop Now and Plan (SNAP) program is a multicomponent intervention for boys between 6 and 11. This study tested putative treatment mechanisms using data from 252 boys in a randomized controlled trial of SNAP versus treatment as usual. SNAP includes a 3 month group treatment period followed by individualized intervention, which persisted through the 15 month study period. Measures were administered in four waves: at baseline and at 3, 9 and 15 months after baseline. A hierarchical linear modeling strategy was used. SNAP was associated with improved problem-solving skills, prosocial behavior, emotion regulation skills, and reduced parental stress. Prosocial behavior, emotion regulation skills and reduced parental stress partially mediated improvements in child aggression. Improved emotion regulation skills partially mediated treatment-related child anxious-depressed outcomes. Improvements in parenting behaviors did not differ between treatment conditions. The results suggest that independent processes may drive affective and behavioral outcomes, with some specificity regarding the mechanisms related to differing treatment outcomes.

  15. [Criteria for treatment of idiopathic scoliosis between 40 degrees and 50 degrees. Surgical vs. conservative therapy].

    PubMed

    Hopf, C

    2000-06-01

    The treatment of idiopathic scoliosis over 40 degrees (Cobb) during the growth period is under discussion concerning the indication for conservative or surgical treatment. Curve progression depends on the degree of the frontal and sagittal deformity, vertebral rotation, rigidity of the curve, the skeletal age, the age and sex of the patient, the familial frequency of scoliosis and the location of the curve. In scoliosis over 40 degrees progression is fast and the possibilities for successful conservative brace treatment are reduced during the growth period. Progression occurs more frequently in thoracic and double major scolioses, especially in young patients (Risser sign 0 and 1). Predictive factors of a successful brace treatment are the correction of scoliosis and rotation; deterioration of both during the brace treatment leads to poor results. Evaluating the flexibility of the sagittal profile is important, as is primary correction of 30-50% in the brace during the 3 months. Operative correction of small primary curves reduces the fusion length, operation time, and blood loss and is followed by a reduction in loading on the adjacent vertebral segments in comparison to the long fusions necessary in more structural and double major scolioses. So far it is not possible to make an equivalent judgment of the frequency of the "crankshaft" phenomenon and the treatment necessary in young patients (Rissersign 0 and 1) treated by dorsal instrumentation alone, but temporary brace treatment may be considered in those cases.

    The efficacy of the treatment with Certifect ® (containing fipronil 6.26% w/v, amitraz 7.48% w/v, (S)-methoprene 5.63% w/v) applied topically was assessed in 18 dogs diagnosed with clinical generalized demodicosis. Three treatment regimens were compared over a 3-month period. Starting at Day 0, dogs were treated monthly (group 1) or every two weeks (group 2) with the combination of fipronil, amitraz, and (S)-methoprene or with monthly topical applications of the combination of amitraz and metaflumizone (group 3, reference treatment). Clinical examinations including deep skin scrapings were performed every month in order to evaluate the resolution of clinical signs and the reduction in mite counts. On Day 84, the percentage reduction of mite counts in group 1 was 99.8%, whereas no Demodex canis could be detected in groups 2 and 3 (i.e. 100% parasitological efficacy). As a result of the Demodex mite count reduction, the skin condition of the dogs improved significantly in all groups. This study illustrates, that both monthly and bi-weekly treatments with Certifect were effective in treating dogs with generalized demodicosis over a 3-month period. PMID:24256940

    Introduction PRINCE-1 is an ongoing prospective, international, multicentre, nonrandomized, two-stage clinical trial assessing safety and efficacy of once-daily atazanavir (ATV) powder boosted with ritonavir (RTV) liquid plus optimized dual nucleoside reverse-transcriptase inhibitor (NRTI) background therapy in antiretroviral (ARV)-naïve and -experienced children with HIV-1 infection aged ≥3 months to <6 years. Methods Children with HIV-1 infection without prior ATV exposure and with a screening HIV-1 RNA ≥1000 copies/mL were enrolled. The dosing of ATV powder, boosted with 80 mg RTV liquid, was based on three baseline weight bands (5 to <10 kg=150 mg, 10 to <15 kg=200 mg and 15 to <25 kg=250 mg). Results Of the 56 treated patients, 46 completed 48 weeks of therapy, 67.9% were from Africa and 60.7% were ART-naïve. Median ages at baseline were 6, 35 and 55 months, and proportions with HIV-1 RNA >100,000 were 85.7, 52.6 and 25% in the three baseline weight bands, respectively. No unexpected safety events occurred and no deaths were reported. Over 48 weeks, upper respiratory tract infections, diarrhoea, vomiting and Grade 3 to 4 hyperbilirubinaemia occurred in 35.7, 35.7, 28.6, and 9.4% of patients, respectively; five patients (8.9%) discontinued due to adverse events (AEs); and 11 patients (19.6%) experienced serious adverse events. At Week 48, using a modified intent-to-treat analysis (two patients were excluded because they switched to ATV capsules before Week 48), 61.1 and 74.1% of patients overall had an HIV-1 RNA level <50 copies/mL and <400 copies/mL, respectively. Virologic suppression rates increased across the lowest to highest baseline weight bands (47.6, 68.4 and 71.4% had HIV-1 RNA <50 copies/mL, and 66.7, 73.7 and 85.7% had HIV-RNA <400 copies/mL, respectively) but did not differ meaningfully between ARV-naïve and -experienced patients. Overall, the median change from baseline in CD4 cell count was +363 cells/mm3, and the median change from

    Objective: To evaluate the safety and efficacy of treating ischemic central retinal vein occlusion (CRVO)with early panretinal photocoagulation(PRP). Methods:24 eyes of 24 cases suffered from ischemic CRVO with history shorter than 3 months were included in this study. PRP treatments were completed through 3 to 5 times of laser therapy with total laser burns of 1000 to 2000(mean 1505+/-384).Patients were followed up 3 months to 2 years, mean 18.4+/-8.0 months.The neovascularization regression and visual acuity were compared before and after PRP, also the long-term complications were observed. Results:3 eyes of iris neovascularization (INV) regressed after PRP and there was no significant difference in visual acuity between prelaser and postlaser. No neovascular glaucoma(NVG) occurred and 2 eyes occurred vitreous hemorrhage during the follow up period.. Conclusions: Early panretinal photocoagulation is safe and efficacious in preventing and reducing complications of ischemic CRVO. It can save valuable treatment time for some patients

    Optimal treatment for distal ureteral stones remains controversial. During a period of 10 years, from December 1992 to December 2002, 103 distal ureteral stones larger than 10 mm in diameter were treated at our institution with extracorporeal shock wave lithotripsy (ESWL) using the Siemens Lithostar. Only 2 patients had a ureteral stent in place at the time of treatment. The overall stone-free rate was 98% with 1-12 session and 3-month stone-free rate was 95.1%. These data reveal that a high success rate was achieved in multisession ESWL. Therefore, ESWL is considered to be acceptable as first-line therapy for fragmentation of distal ureteral stones larger than 10 mm in diameter.

    A 38-year-old male suffered from swelling of the lower lip for 3 months. Neither facial nerve palsy nor fissuring of the tongue was present. Histological examination of a biopsy taken from the lower lip revealed non-caseous epithelioid cell granulomas, suggestive of cheilitis granulomatosa. Patch testing revealed positive reactions to mercury chloride and amalgam. His symptoms markedly improved 3 months after treatment of the apical periodontitis and replacement of dental crowns. As his dental crowns did not contain mercury, we believe that the cheilitis granulomatosa may have been related to the focal dental infection. PMID:21941479

    2015-01-01

    SYNOPSIS In the United States, Lyme arthritis is the most common feature of late stage infection with the tick-borne spirochete, Borrelia burgdorferi, usually beginning months after the initial tick bite. However, in some patients, including most of those seen today, the earlier phases of the infection are asymptomatic and arthritis is the presenting manifestation of the disease. Patients with Lyme arthritis have intermittent or persistent attacks of joint swelling and pain in one or a few large joints, especially the knee, usually over a period of several years, without prominent systemic manifestations. Serologic testing is the mainstay of diagnosis. Synovial fluid PCR testing for B. burgdorferi DNA is often positive prior to treatment, but it is not a reliable marker of spirochetal eradication after antibiotic therapy. Responses to oral or intravenous antibiotic treatment are generally excellent, although a small percentage of patients have persistent synovitis after 2-3 months of oral and IV antibiotics, which usually then responds to anti-inflammatory therapies, disease modifying anti-rheumatic drugs (DMARDs), or synovectomy. This chapter reviews the clinical manifestations, diagnosis, and management of Lyme arthritis. PMID:25999223

    Central serous chorioretinopathy (CSC) is a retinal disorder that primarily affects young (20- to 50-year-old) white men, although it is seen occasionally in older patients and females. CSC is characterized by avascular focal leakage through the retinal pigment epithelium (RPE), resulting in serous detachment of the neurosensory retina. The course is usually self-limiting and in most cases resolves spontaneously within a 3-month period, with visual acuity usually recovering to 20/30 or better. However, chronic CSC may develop as a consequence of recurrences or persistent neurosensory detachment, and can result in progressive RPE atrophy and permanent visual loss. A primary involvement of the RPE and choroidal vascularization play a significant role in the pathogenesis of CSC and the current treatment options attempt to restore the functions of the RPE and the normal choroidal vasculature. The aim of the current review is to provide an overview of the current therapeutical approaches to CSC, including observation, laser treatment, photodynamic therapy with verteporfin, intravitreal anti-vascular endothelial growth factor therapy and the mineralocorticoid receptor antagonists.

    Glucocorticoids administered to prevent respiratory distress in preterm infants are associated with neurodevelopmental disorders. To evaluate the long-term effects on forebrain development, we treated developing rats with dexamethasone (Dex) at 0.05, 0.2, or 0.8 mg/kg, doses below or spanning the range in clinical use, testing the effects of administration during three different stages: gestational days 17-19, postnatal days 1-3, or postnatal days 7-9. In adulthood, we assessed biomarkers of neural cell number and size, cholinergic presynaptic activity, neurotransmitter receptor expression, and synaptic signaling mediated through adenylyl cyclase (AC), in the cerebral cortex, hippocampus, and striatum. Even at doses that were devoid of lasting effects on somatic growth, Dex elicited deficits in the number and size of neural cells, with the largest effect in the cerebral cortex. Indices of cholinergic synaptic function (choline acetyltransferase, hemicholinium-3 binding) indicated substantial hyperactivity in males, especially in the hippocampus, effectively eliminating the normal sex differences for these parameters. However, the largest effects were seen for cerebrocortical cell signaling mediated by AC, where Dex treatment markedly elevated overall activity while obtunding the function of G-protein-coupled catecholaminergic or cholinergic receptors that stimulate or inhibit AC; uncoupling was noted despite receptor upregulation. Again, the effects on signaling were larger in males and offset the normal sex differences in AC. These results indicate that, during critical developmental periods, Dex administration evokes lasting alterations in neural cell numbers and synaptic function in forebrain regions, even at doses below those used in preterm infants.

    An unique and intriguing characteristic of lysergic acid diethylamide (LSD) and LSD-like substances is the recurrence of some of the symptoms which appear during the intoxication, in the absence of recent intake of hallucinogens. Hallucinogen persisting perception disorder (HPPD) is a condition in which the re-experiencing of one or more perceptual symptoms causes significant distress or impairment in social, occupational or other important areas of functioning and may be extremely debilitating. Benzodiazepines are one of the recommended agents for the treatment of HPPD but it is unclear which of them may be more helpful. The goal of our investigation was to assess the efficacy of clonazepam in the treatment of LSD-induced HPPD. Sixteen patients fulfilled entrance criteria. All complained of HPPD with anxiety features for at least 3 months and were drug free at least 3 months. They received clonazepam 2 mg/day for 2 months. Follow-up was continued for 6 months. They were weekly evaluated during the 2 months of clonazepam administration and monthly during the follow-up period using the Clinical Global Impression Scale, a Self-report Scale and Hamilton Anxiety Rating Scale. Patients reported a significant relief and the presence of only mild symptomatology during the clonazepam administration. This improvement was clearly sustained and persisted during a 6-month follow-up period. This study suggests that high potency benzodiazepines like clonazepam, which has serotonergic properties, may be more effective than low-potency benzodiazepines in the treatment of some patients with LSD-induced HPPD.

    Background Buprenorphine opioid agonist treatment (OAT) has established efficacy for treating opioid dependency but early relapse rates are high and are often associated with withdrawal-related or emotional distress. Methods To determine whether a novel distress tolerance (DT) intervention during buprenorphine initiation decreases opioid relapse, we conducted a preliminary randomized controlled trial with opioid-dependent outpatients. Participants received buprenorphine-naloxone induction and 3-months of maintenance buprenorphine plus seven, 50-minute manualized, individual sessions (DT vs. Health Education (HE) control) over a 28-day period, linked to clinician medication dosing visits, and beginning 2 days prior to buprenorphine induction. Primary outcomes included use of illicit opioids (positive defined as any self-reported use in the prior 28 days or detected by urine toxicology) and treatment drop out. Results Among 49 participants, the mean age was 41 years, 65.3% were male. Persons randomized to DT had lower rates of opioid use at all three monthly assessments, and at 3-months, 72% of HE participants were opioid positive compared with 62.5% of DT participants. Rates of dropout were 24% and 25% in the HE and DT arms, respectively. Conclusions This distress tolerance treatment produced a small, but not statistically significant reduction in opioid use during the first three months of treatment although no differences were found in drop-out rates between conditions. If replicated in a larger study, DT could offer clinicians a useful behavioral treatment to complement the effects of buprenorphine. Trial registered at clinicaltrials.org. Trial number NCT01556087.

    The terrestrial cyanobacterium Nostoc flagelliforme Berk. et M. A. Curtis has been a popular food and herbal ingredient for hundreds of years. To meet great market demand and protect the local ecosystem, for decades researchers have tried to cultivate N. flagelliforme but have failed to get macroscopic filamentous thalli. In this study, single trichomes with 50 to 200 vegetative cells were induced from free-living cells by low light and used to investigate the morphogenesis of N. flagelliforme under low UV-B radiation and periodic desiccation. Low-fluence-rate UV-B (0.1 W m(-2)) did not inhibit trichome growth; however, it significantly increased the synthesis of extracellular polysaccharides and mycosporine-like amino acids and promoted sheath formation outside the trichomes. Under low UV-B radiation, single trichomes developed into filamentous thalli more than 1 cm long after 28 days of cultivation, most of which grew separately in liquid BG11 medium. With periodic desiccation treatment, the single trichomes formed flat or banded thalli that grew up to 2 cm long after 3 months on solid BG11 medium. When trichomes were cultivated on solid BG11 medium with alternate treatments of low UV-B and periodic desiccation, dark and scraggly filamentous thalli that grew up to about 3 cm in length after 40 days were obtained. In addition, the cultivation of trichomes on nitrogen-deficient solid BG11 medium (BG11(0)) suggested that nitrogen availability could affect the color and lubricity of newly developed thalli. This study provides promising techniques for artificial cultivation of N. flagelliforme in the future.

    One hundred and seventy-two fixed reconstructions (317 prosthetic units), made on 283 ITI implants in 105 patients (age range 25-86 years) with a minimum follow-up period of 40 months, were taken into the study to analyse technical complication rate, complication type and costs for repair. The mean evaluation time was 62.5 +/- 25.3 months. Eighty were single crowns and 92 different types of fixed partial dentures (FPDs). In 45 cases the construction was screw retained and in 127 cases cemented with zinc phosphate cement or an acrylic-based cement. Complications occurred after a minimum period of 2 months and a maximum period of 100 months (mean: 35.9 +/- 21.4 months). Fifty-five prosthetic interventions were needed on 44 constructions (25%) of which 88% in the molar/premolar region. The lowest percentage of complications occurred in single crowns (25%), the highest in 3-4 unit FPDs (35%) and in FPDs with an extension (44%). Of the necessary clinical repair, 36% was recementing and 38% tightening the screws. Of all interventions, 14% were classified as minor (no treatment or <10 min chair time), 70% as moderate (>10 min but <60 min chair time) and 14% as major interventions (>60 min and additional costs for replacement of parts and/or laboratory). For seven patients the additional costs ranged from euro 28 to euro 840. Bruxing seemed to play a significant role in the frequency of complications. Longer constructions seemed to be more prone to complications. The relatively high occurrence of technical complications should be discussed with the patient before the start of the treatment.

  17. Saturn's variable radio period

    Kurth, W. S.; Lecacheux, A.; Zarka, P.; Gurnett, D. A.; Cecconi, B.

    Temporal modulations in radio emissions are often used to determine the rotation rate of the emitting body. The rotation period (presumably) of Jupiter's interior was established in this way [Burke et al., 1962] and has recently been refined by Higgins et al. [1997]. Rotation periods for the remainder of the outer planet gas giants were determined from Voyager planetary radio astronomy observations. Similar techniques have been applied to astrophysical objects, including pulsars, for which the radio period is assumed to be the rotation period of the neutron star. In 2001, however, this simple relation between the radio period and rotation period became suspect, at least for the case of Saturn. Galopeau and Lecacheux [2001] reported that the radio period of Saturn had changed by as much as 1% from that determined by Voyager and, further, exhibited variations on time scales of years. More recently, Cassini observations indicate that the Saturn kilometric radiation is modulated with a period longer than that observed by Voyager and that this period is variable on a time scale of a year or less. The recent Higgins et al. result suggests that Jupiter's period is steady, within measurement accuracy. There are no additional measurements from Uranus or Neptune with which to look for time variations in their radio periods. For conservation of energy and angular momentum reasons, true variations of the rotation period of Saturn's deep interior are not believed to be a viable explanation for the variation in radio period, hence, it would appear that there is some disconnection of the radio period from the rotation period in the case of Saturn. One possible contributing factor may be that since Saturn's magnetic field is very accurately aligned with its rotational axis, there is no first-order beaming effect caused by the wobbling of the magnetic field, contrary to the situation at the other magnetized planets. Another explanation suggested by Galopeau and Lecacheux [2001] and

  1. Hyperkalemic periodic paralysis associated with multiple sleep onset REM periods.

    PubMed

    1999-12-15

    A 24-year-old man with sporadic hyperkalemic periodic paralysis (HPP) presented with moderate excessive daytime sleepiness and transitory episodes of weakness which occurred during and after sleep. Multiple sleep latency test (MSLT) demonstrated the presence of five sleep onset REM periods (SOREMPs) and a sleep latency of five minutes. Treatment with a diuretic which decreases serum potassium resolved all the clinical symtomps and a new MSLT showed the absence of SOREMPs and a sleep latency of 13.5 minutes. To our knowledge, the patient herein reported is the first case that associates sleep abnormalities and multiple SOREMPs with HPP. Furthermore, the present case suggests that SOREMPs may be explained by an increased extracellular potassium conductance related to HPP.

  2. [TREATMENT MODALITIES OF LABIAL FUSION IN PREPUBERTAL GIRLS].

    PubMed

    Morić, Bernardica Valent; Lesar, Tatjana

    2014-12-01

    Labial adhesion is a thin membranous fusion of the labia minora of varying length. It is not a rare condition in prepubertal girls, but since it is often asymptomatic, it remains undiagnosed. It is usually discovered during regular check-ups or when the fusion results in post-void dripping, bacteriuria, vaginal irritation, dysuria, urinary tract infection or obstruction. The cause of labial adhesions is unclear. Chronic irritation of the vulva in combination with poor hygiene is believed to be important etiologic factors. A theory of hypoestrogenic status in prepubertal girls as a potential etiologic factor for labial adhesions is no longer widely accepted, since a recent study concluded that there was no difference in estrogen levels between children with and those without labial adhesions. Treatment options include conservative management with topical estrogen or betmethasone creams or, when indicated, manual separation or surgery. Topical estrogen and betamethasone creams are generally considered safe and effective treatment of labial adhesions, even over prolonged periods of time, with minimal if any side effects. No guidelines have been structured for the limits or duration of topical therapy, but most authors agree that optimal treatment should last from 1 to 2 or 3 months on twice-a-day regimen. Parental education concerning appropriate application technique is important not only for the success of treatment, but also to avoid the possible side effects. PMID:26285472

    Clients in a community-based methadone treatment program earned stars for attending counseling sessions as scheduled and for providing clean urines. These stars were later redeemed for contingent rewards (food or gas coupons or bus tokens) according to one of three randomly assigned reward schedules, including high reward (four stars per prize), low reward (eight stars per prize), or delayed reward (those who had to wait 3 months to earn a prize). Clients in the high-reward condition showed a pattern of increasing the number of stars earned for group sessions and clean urines across the 3-month intervention. All clients, independent of reward condition, attended significantly more group counseling sessions during the months that contingent reinforcers were available than in the months prior to, and after, the intervention. Finally, urinalysis data indicated that, in the postintervention period, high-reward clients had fewer dirty urines than did low-reward or delayed-reward clients. This study suggests that a simple system of recognizing client progress with stars and modest prizes for performing specific behaviors can be an effective tool in increasing clinic attendance rates and reducing positive urines.

    Tardive dystonia is an iatrogenic complication of dopamine receptor antagonist medication such as first-generation antipsychotics. It occurs in up to 2% of patients and only 10% recover after stopping medication. Deep brain stimulation for primary dystonia has proven to be effective and its application for secondary dystonias is gaining acceptance. We report our experience in treating three ethnic Chinese schizophrenia patients with severe medically refractory tardive dystonia by globus pallidus internus deep brain stimulation. Preoperatively, all required assistance with essential activities of daily living and two were bed-bound. The mean Burke-Fahn-Marsden Dystonia Rating Scale score was 61 (range, 44-80) and mean Global Dystonia Rating Scale score was 47 (range, 40-52). No procedure-related complications were encountered. By 3 months all could return to unassisted living and walk with support with a mean of 77% and 66% improvement in the Burke-Fahn-Marsden Dystonia Rating Scale and Global Dystonia Rating Scale scores, respectively. Quality-of-life assessment performed for two patients using the EuroQol-5 dimensions visual analogue scale showed a mean improvement of 86% at 3 months. On clinical follow-up, the effect was well maintained for a period of 3 to 10 years. Pallidal deep brain stimulation is a safe and highly effective form of symptomatic treatment for patients with medically refractory tardive dystonia.

    Context Treatment satisfaction with a loading phase of monthly injections for 3 months followed by a pro-re-nata regimen of ranibizumab in neovascular age-related macular degeneration (nAMD) remains unclear. Aims The aim was to evaluate the treatment satisfaction of persons with nAMD treated with ranibizumab in a real-life setting. Settings and design A cross-sectional study was conducted across three eye clinics within the National Health Service in the UK, where treatment is provided free at point of contact. Materials and methods A total of 250 patients were selected randomly for the study. Treatment satisfaction was assessed using the Macular Treatment Satisfaction Questionnaire. Data were collected on satisfaction of the service provided (Client Service Questionnaire-8) and the patients’ demographic and quality of life and treatment history. Factors governing treatment questionnaire were determined. Results The most important factors that determined the satisfaction were the service provided at the clinic (Client Service Questionnaire-8), health-related quality of life (EQ-5D-3L), and duration of AMD. Visual acuity changes were rated as less important than one would have expected. Conclusion The study result suggested that treatment satisfaction for nAMD was governed by the perception of being reviewed and injected regularly over a long period of time than the actual change in visual acuity from the treatment.

    Mature rats (starting weight at least 270 g) were treated daily with cannabis extract (daily THC dose 20 mg/kg) for 3 months. After a 1- to 4-month drug-free period, residual effects on a variety of behaviors were studied. No residual effects were found in learning of an eight-arm radial maze task, nor on a differential reinforcement of low-rate responding (DRL-20) task, nor on open field activity. On the other hand, two-way shuttle box avoidance learning was facilitated by previous cannabis treatment, since cannabis-treated rats exhibited shorter mean latencies to avoid footshock than vehicle controls. The findings indicate greater vulnerability of immature organisms (previous studies) than mature organisms (the present study) to long-term effects of chronic cannabis administration.

    Purpose: To investigate the rates of tumor response and local control in patients with recurrent small hepatocellular carcinoma (HCC) treated with hypofractionated radiotherapy (RT) as a salvage treatment and to evaluate treatment-related toxicities. Methods and Materials: Between 2006 and 2009, a total of 20 patients with recurrent small HCC were treated with hypofractionated RT after the failure of previous treatment. The eligibility criteria for hypofractionated RT were as follows: 1) HCC less than 5 cm, 2) HCC not adjacent to critical organs, 3) HCC without portal vein tumor thrombosis, and 4) less than 15% of normal liver volume that would be irradiated with 50% of prescribed dose. The RT dose was 50 Gy in 10 fractions. The tumor response was determined by CT scans performed 3 months after the end of RT. Results: The median follow-up period after RT was 22 months. The overall survival rates at 1 and 2 years were 100% and 87.9%, respectively. Complete response (CR) was achieved in seven of 20 lesions (35%) evaluated by CT scans performed 3 months after the end of RT. In-field local control was achieved in 85% of patients. Fourteen patients (70%) developed intra-hepatic metastases. Six patients developed grade 1 nausea or anorexia during RT, and two patients had progression of ascites after RT. There was no grade 3 or greater treatment-related toxicities. Conclusions: The current study showed a favorable outcome with respect to hypofractionated RT for small HCC. Partial liver irradiation with 50 Gy in 10 fractions is considered tolerable without severe complications.

    Cancers exhibit differences in metastatic behavior and drug sensitivity that correlate with certain tumor-specific variables such as differentiation grade, growth rate/extent and molecular regulatory aberrations. In practice, patient management is based on the past results of clinical trials adjusted for these biomarkers. Here, it is proposed that treatment strategies could be fine-tuned upfront simply by quantifying tumorigenic spatial (cell growth) and temporal (genetic stability) control losses, as predicted by genetic defects of cell-cycle-regulatory gatekeeper and genome-stabilizing caretaker tumor suppressor genes, respectively. These differential quantifications of tumor dysfunction may in turn be used to create a tumor-specific 'periodic table' that guides rational formulation of survival-enhancing anticancer treatment strategies.

    Aim of the study The purpose of the study was to monitor the effect of ulipristal acetate treatment on symptomatic uterine fibroids within 12-months follow-up. Material and methods Fifty six patients with symptomatic uterine fibroids qualified for surgical treatment were included in the prospective observational study. All patients received preoperative oral UPA treatment for 3 months (1 × 5 mg). Patients that refused surgical treatment after UPA therapy were followed-up for the next 9 months. The volume of the intramural fibroid was estimated by TV-US using and integrated VOCAL 3D imaging program at baseline, after 3 months of UPA treatment and further at 3-months intervals. Results Before UPA mean dominant fibroid volume was estimated to be 216.0 cm3 (38.4-768.2 cm3) and decreased to 117.6 cm3 (12.6-668.0 cm3) after 3 months of UPA therapy. Mean percentage volume reduction was 45.6%. Mean hemoglobin level increased from an initial 10.1 g/dL (6.8-12.9 g/dL) to 12.6 g/dL (10.1-14.8) after 3 months of UPA therapy. At 12 months after initiating UPA treatment mean dominant fibroid volume decreased by 43.9%. In one third of followed-up patients the effect of 3 month UPA therapy persisted for the next 9 months. Conclusions Three month UPA therapy decreases fibroid volume and improves hemoglobin level before planned surgical treatment. In one third of followed-up patients the effect of 3 month UPA therapy persisted for the next 9 months. PMID:26327823

    Hyperthyroid periodic paralysis (HPP) is a rare life threatening complication of hyperthyroidism commonly occurring in young Asian males but sporadically found in other races. It is characterised by hypokalemia and acute onset paraparesis with prevalence of one in one hundred thousand (1 in 100000). The symptoms resolve promptly with potassium supplementation. Nonselective beta blockers like propranol can also be used to ameliorate and prevent subsequent paralytic attack.

    Periodically kicked turbulence is theoretically analyzed within a mean-field theory. For large enough kicking strength A and kicking frequency f the Reynolds number grows exponentially and then runs into some saturation. The saturation level Re(sat) can be calculated analytically; different regimes can be observed. For large enough Re we find Re(sat) approximately Af, but intermittency can modify this scaling law. We suggest an experimental realization of periodically kicked turbulence to study the different regimes we theoretically predict and thus to better understand the effect of forcing on fully developed turbulence.

  6. Spontaneous periodic hypothermia.

    PubMed

    Kloos, R T

    1995-09-01

    Spontaneous periodic hypothermia is a rare syndrome of recurrent, centrally mediated hypothermia without an identifiable systemic cause or brain lesion. Most patients defend a temporarily lowered temperature "set point" during episodes of hypothermia, despite manifesting many well-known systemic consequences of core temperature hypothermia. No case of death directly attributable to an episode of spontaneous periodic hypothermia has been reported, although many of the serious systemic effects of hypothermia have been documented in these cases, so it is not unlikely that death may occur. The syndrome's cause, and that of Shapiro syndrome, remains unknown. Pharmacologic trials to date have been only modestly successful. Anticonvulsant agents, clonidine, and cyproheptadine appear the most likely to succeed, with cyproheptadine being a reasonable first choice. Given that the term "spontaneous periodic hypothermia" describes a syndrome, and not a pathophysiologic mechanism, it is likely to encompass a common eventuality, arrived at via several different pathways. One can postulate mechanisms such as structural abnormalities, trauma, infection, irritation, and degeneration involving strategic locations which create a focus for epileptic or other periodic dysfunction whose scope involves the centers for thermoregulation. The existence of 2 distinct, oppositional thermoregulatory centers would allow for speculation of similar mechanisms accounting for cases of both periodic hypo- and hyperthermia (61). Postmortem data regarding the hypothalamic and surrounding areas from future cases of Shapiro syndrome and spontaneous periodic hypothermia would be of great interest. Further, more sensitive in vivo testing methods are clearly needed. The role of PET or single photon emission computed tomography (SPECT) with technetium 99m-labeled hexamethylpropylene amine oxime (Tc 99m HMPAO) performed acutely during an episode remains to be characterized (64, 103, 105).

    The aim of the present study was to compare deep lamellar endothelial keratoplasty (DLEK) and penetrating keratoplasty (PK) treatments for bullous keratopathy (BK). In total, 36 healthy New Zealand white rabbits were randomly divided into 3 groups termed the experimental, DLEK and PK groups. The experimental control group received no treatment. The DLEK and PK groups were observed for corneal astigmatism at 1, 2, or 3 months post-surgery using a corneal topography instrument and a slit lamp microscope. The incidence of immune rejection after 3 months of recovery was determined using hematoxylin and eosin (H&E) staining. The corneal specimens from the surgery groups were compared with those from the control group. In the 12 rabbit eyes that underwent the DLEK surgery, the central cornea became clear after 1 week. After 3 months, these corneas were almost transparent and no eye infections or other complications were observed in 10 of the eyes, while surgical perforations in 2 eyes led to surgical lamellar failure. In the PK surgery group, in which 12 rabbit eyes were also treated, nine were almost transparent after 3 months of recovery, while three eyes were immunologically rejected due to the corneal grafts. The occur-rences of corneal astigmatism that were observed following DLEK and PK treatment were significantly different after 1, 2 and 3 months of recovery (P<0.05). Normal corneal staining was observed in the DLEK and PK rabbits subjected to H&E staining after 3 months of recovery. A BK animal model was established by curetting the Descemet’s membrane (DM film). In comparison with PK, DLEK is a superior surgical treatment for BK. PMID:23737903

    Objective: To explore the effects of a new management model of comprehensive treatments of acute spinal cord injury (SCI) on clinical application. Methods: From January 2010 to January 2011, there were 89 patients with acute SCI over the same admission period, including 32 cases divided into the management model group and the other 57 into the control group. Respectively, at the 1, 3 and 6 months after treatment, the score standardization, developed by the American Association of spinal cord injury (ASIA), was used to assess the motor and sensory function during the admission period. At the same time, a follow-up survey was made to investigate the satisfaction of patients and their families. Results: At 1 and 3 months after treatment, the motor and feeling function scores of patients in the experimental group both improved significantly compared with the control group, and the differences were statistically significant (P<0.05). In addition, six months after treatment, the motor and sensory function scores of patients in the control group were not significantly improved any longer; while those scores in the experimental group still significantly recovered, and the difference between experimental and control groups was also statistically significant (P<0.05). According to the follow-up, patients and their families in the experimental group were of greater satisfaction than the control group (P<0.05). Conclusions: The management model of acute SCI treatment performed perfect clinical effects, and was worth promoting. PMID:26464687

    Bulk centrosymmetric silicon lacks second-order optical nonlinearity χ(2) - a foundational component of nonlinear optics. Here, we propose a new class of photonic device which enables χ(2) as well as quasi-phase matching based on periodic stress fields in silicon - periodically-poled silicon (PePSi). This concept adds the periodic poling capability to silicon photonics, and allows the excellent crystal quality and advanced manufacturing capabilities of silicon to be harnessed for devices based on χ(2)) effects. The concept can also be simply achieved by having periodic arrangement of stressed thin films along a silicon waveguide. As an example of the utility, we present simulations showing that mid-wave infrared radiation can be efficiently generated through difference frequency generation from near-infrared with a conversion efficiency of 50% based on χ(2) values measurements for strained silicon reported in the literature [Jacobson et al. Nature 441, 199 (2006)]. The use of PePSi for frequency conversion can also be extended to terahertz generation. With integrated piezoelectric material, dynamically control of χ(2)nonlinearity in PePSi waveguide may also be achieved. The successful realization of PePSi based devices depends on the strength of the stress induced χ(2) in silicon. Presently, there exists a significant discrepancy in the literature between the theoretical and experimentally measured values. We present a simple theoretical model that produces result consistent with prior theoretical works and use this model to identify possible reasons for this discrepancy.

    Two remarkable discoveries of the last decade have profound implications for astrophysics and for geophysics. These are the discovery by Alvarez et al., that certain mass extinctions are caused by the impact on the earth of a large asteroid or comet, and the discovery by Raup and Sepkoski that such extinctions are periodic, with a cycle time of 26 to 30 million years. The validity of both of these discoveries is assumed and the implications are examined. Most of the phenomena described depend not on periodicity, but just on the weaker assumption that the impacts on the earth take place primarily in showers. Proposed explanations for the periodicity include galactic oscillations, the Planet X model, and the possibility of Nemesis, a solar companion star. These hypotheses are critically examined. Results of the search for the solar companion are reported. The Deccan flood basalts of India have been proposed as the impact site for the Cretaceous impact, but this hypotheisis is in contradiction with the conclusion of Courtillot et al., that the magma flow began during a period of normal magnetic field. A possible resolution of this contradiction is proposed.

    Purpose. To describe the presentation, treatment, and outcomes for 14 patients with aneurysms of the inferior pancreaticoduodenal arteries associated with occlusive lesions of the celiac axis, and to review the literature for similar cases. Methods, Over a period of 12 years, 14 patients (10 women and 4 men) ranging in age from 26 to 50 (mean 46) years were demonstrated to have aneurysms of the inferior pancreaticoduodenal artery origin associated with stenosis or occlusion of the celiac axis. All patients were treated by a combination of surgery and interventional radiology. Results. Outcome data collected between 3 months and 4 years (mean 2 years) demonstrated that all aneurysms remained excluded, and all 14 patients were well. The 49 case reports in the literature confirm the findings of this cohort. Conclusion. In inferior pancreaticoduodenal artery aneurysm resulting from celiac occlusive disease, endovascular treatment is best achieved by stenting the celiac axis and/or embolizing the aneurysm when necessary.

    Since 1990 the WHO Global Tuberculosis Programme (GTB) has promoted the revision of national tuberculosis programmes to strengthen the focus on directly observed treatment, short-course (DOTS) and close monitoring of treatment outcomes. GTB has encouraged in-depth evaluation of activities through a comprehensive programme review. Over the period 1990-95, WHO supported 12 such programme reviews. The criteria for selection were as follows: large population (Bangladesh, Brazil, China, Ethiopia, India, Indonesia, Mexico, and Thailand); good prospects of developing a model programme for a region (Nepal, Zimbabwe); or at advanced stage of implementation of a model programme for a region (Guinea, Peru). The estimated combined incidence of smear-positive pulmonary tuberculosis was 82 per 100,000 population, about 43% of the global incidence. The prevalence of infection with human immunodeficiency virus (HIV) was variable, being very high in Ethiopia and Zimbabwe, but negligible in Bangladesh, China, Nepal and Peru. The programme reviews were conducted by teams of 15-35 experts representing a wide range of national and external institutions. After a 2-3-month preparatory period, the conduct of the review usually lasted 2-3 weeks, including a first phase of meetings with authorities and review of documents, a second phase for field visits, and a third phase of discussion of findings and recommendations. The main lessons learned from the programme reviews were as follows: programme review is a useful tool to secure government commitment, reorient the tuberculosis control policies and replan the activities on solid grounds; the involvement of public health and academic institutions, cooperating agencies, and nongovernmental organizations secured a broad support to the new policies; programme success is linked to a centralized direction which supports a decentralized implementation through the primary health care services; monitoring and evaluation of case management functions

    We studied efficacy of repeated courses of prostatilen in suppositories with dimexide in prostatic adenoma patients with normal micturition. Rectal suppositories contain 30 mg prostatilen and 90 mg dimexide. The course consisted of 15 suppositories. The treatment reduced clinical symptoms of infravesical obstruction, residual urine volume in administration of prostatilen in 15-day courses each 3 months. This suggests possibility of suppository prostatilen use not only as an alternative for expensive drugs but also in combination with them in treatment of initial prostatic adenoma.

    Introduction In cancer patients, the chest computer tomography (CT) can be used to identify asymptomatic pulmonary embolism (APE). In most cases, these patients are treated with anticoagulant drugs for at least 3 months. The American College of Physicians recommend treatment of these patients as patients with symptomatic pulmonary embolism. In this study, we evaluated and compared the efficacy and safety of fondaparinux vs warfarin in the prevention of unsuspected pulmonary embolism in patients with active cancer. Materials and methods A prospective and parallel group study was performed on 64 cancer patients (29 males and 35 females) with APE. A multidetector CT angiography with high spatial and temporal resolution and quality of arterial opacification was used to make the diagnosis. Lung scintigraphy was reserved to selected patients only. Patients were randomized to either the warfarin (Group A) or the fondaparinux (Group B) for 90 days. The first end point of efficacy was the persistence, reduction, or disappearance of thrombosis after 90 days. The second end point was the reappearance of thrombosis after 1 year. The first end point of safety was the development of major bleeding. Results We enrolled 32 patients into each treatment group. We reached the first end point of efficacy and safety in Group B which showed that fondaparinux was able to induce the disappearance of thrombotic pulmonary with a lower incidence of major bleeding events compared with warfarin. No difference in the secondary end point was recorded. Conclusion We suggest that the treatment of cancer patients with APE can be oriented with the administration of a standard dose of fondaparinux until the next CT lung control (3 months). However, the lack of a randomized clinical trial, including a larger patient cohort, does not allow formulation of final recommendations in these patients. A broader study would be desirable, involving a larger number of patients and a longer follow-up period. PMID

  20. Cells anticipate periodic events

    We show that an amoeboid organism can anticipate the timing of periodic events. The plasmodium of the true slime mold Physarum polycephalum moves rapidly under favourable conditions, but stops moving when transferred to less-favourable conditions. Plasmodia exposed to unfavourable conditions, presented in three consecutive pulses at constant intervals, reduced their locomotive speed in response to each episode. When subsequently subjected to favourable conditions, the plasmodia spontaneously reduced their locomotive speed at the time point when the next unfavourable episode would have occurred. This implied anticipation of impending environmental change. After this behaviour had been evoked several times, the locomotion of the plasmodia returned to normal; however, the anticipatory response could subsequently be induced by a single unfavourable pulse, implying recall of the memorized periodicity. We explored the mechanisms underlying these behaviours from a dynamical systems perspective. Our results hint at the cellular origins of primitive intelligence and imply that simple dynamics might be sufficient to explain its emergence.

    Treatment of latent tuberculosis infection (LTBI) is essential for eradicating tuberculosis (TB). Moreover, the patient adherence is crucial in determining the effectiveness of TB control. Isoniazid given by DOTS daily for 9 months (9H) is the standard treatment for LTBI in Taiwan. However, the completion rate is low due to the long treatment period and its side effects. The combined regimen using a high dose of rifapentine/isoniazid once weekly for 12 weeks (3HP) has been used as an alternative treatment option for LTBI in the United States. This may result in a higher completion rate. In this pilot study, patient adherence and cost of these 2 treatment regimens were investigated. Thus, we aimed to assess the treatment completion rate and costs of 3HP and compare to those with 9H.Data from 691 cases of LTBI treatments including 590 cases using the conventional regimen and 101 cases with rifapentine/Isoniazid were collected. The cost was the sum of the cost of treatment with Isoniazid for 9 months or with rifapentin/Isoniazid for 3 months of all contacts. The effectiveness was the cost of cases of tuberculosis avoided.In this study, the treatment completion rate for patients prescribed with the 3 months rifapentine/isoniazid regimen (97.03%) was higher than those given the conventional 9-month isoniazid regimen (87.29%) (P <0.001). The cost of 3HP and 9H was US$261.24 and US$717.3, respectively. The cost-effectiveness ratio with isoniazid for 9 months was US$ 15392/avoided 1 case of tuberculosis and US$ 5225/avoided 1 case of tuberculosis with 3HP. In addition, when compared with the conventional regimen, there were fewer patients discontinued with rifapentine/isoniazid regimen due to undesirable side effects.This was the first study to compare the 2 treatment regimens in Taiwan, and it showed that a short-term high-dosage rifapentine/isoniazid treatment regimen reduced costs and resulted in higher treatment completion than the standard LTBI isoniazid treatment

  2. Periodic minimal surfaces

    A minimal surface is one for which, like a soap film with the same pressure on each side, the mean curvature is zero and, thus, is one where the two principal curvatures are equal and opposite at every point. For every closed circuit in the surface, the area is a minimum. Schwarz1 and Neovius2 showed that elements of such surfaces could be put together to give surfaces periodic in three dimensions. These periodic minimal surfaces are geometrical invariants, as are the regular polyhedra, but the former are curved. Minimal surfaces are appropriate for the description of various structures where internal surfaces are prominent and seek to adopt a minimum area or a zero mean curvature subject to their topology; thus they merit more complete numerical characterization. There seem to be at least 18 such surfaces3, with various symmetries and topologies, related to the crystallographic space groups. Recently, glyceryl mono-oleate (GMO) was shown by Longley and McIntosh4 to take the shape of the F-surface. The structure postulated is shown here to be in good agreement with an analysis of the fundamental geometry of periodic minimal surfaces.

    Purpose: To evaluate the intra-fractional prostate movement range during the beam delivery and implement new IGRT method to correct the prostate movement during the hypofractionated prostate treatment delivery. Methods: To evaluate the prostate internal motion range during the beam delivery, 11 conventional treatments were utilized. Two-arc RapidArc plans were used for the treatment delivery. Orthogonal KV imaging is performed in the middle of the treatment to correct intra-fractional prostate movement. However, it takes gantry-mounted on-board imaging system relative long time to finish the orthogonal KV imaging because of gantry rotation. To avoid gantry movement and accelerate the IGRT processing time, orthogonal KV-MV image pair is tested using the OBI daily QA Cube phantom. Results: The average prostate movement between two orthogonal KV image pairs was 0.38cm (0.20cm ∼ 0.85cm). And the interval time between them was 6.71 min (4.64min ∼ 9.22 min). 2-arc beam delivery time is within 3 minutes for conventional RapidArc treatment delivery. Hypofractionated treatment or SBRT need 4 partial arc and possible non-coplanar technology, which need much longer beam delivery time. Therefore prostate movement might be larger. New orthogonal KV-MV image pair is a new method to correct the prostate movement in the middle of the beam delivery if real time tracking method is not available. Orthogonal KV-MV image pair doesn’t need gantry rotation. Images were acquired quickly which minimized possible new prostate movement. Therefore orthogonal KV-MV image pair is feasible for IGRT. Conclusion: Hypofractionated prostate treatment with less PTV margin always needs longer beam delivery time. Therefore prostate movement correction during the treatment delivery is critical. Orthogonal KV-MV imaging pair is efficient and accurate to correct the prostate movement during treatment beam delivery. Due to limited fraction number and high dose per fraction, the MV imaging dose is

    The objective of this study was to evaluate the effect of two synthetic progestagen preparations Chlormadinone acetate (CAP, Chronosyn, Veterinaria AG Zürich) and Medroxyprogesterone acetate (MPA, Nadigest, G Streuli & Co. Uznach) on cycling activity and fertility in sheep. A flock of 28 non pregnant white alpine sheep was randomly divided into three groups, A (n = 10), B (n = 9) and C (n = 9). During a period of 4 weeks the cycling activity was confirmed by blood progesterone analysis. Thereafter, the animals of group A were treated with 50 mg CAP, those of group B with 140 mg MPA and those of group C with physiological saline solution. All injections were given intramuscularly. Suppression of endogenous progesterone secretion lasted from 28 to 49 days (mean = 39 days) in group A and from 42 to 70 days (mean = 50 days) in group B. The synchronization effect of both preparations was unsatisfactory as the occurrence of first estrus was distributed over a period of 3 weeks in group A and 4 weeks in group B. These findings could also be confirmed by the lambing period which lasted 52 days in group A and 36 days in group B. Control animals lambed within 9 days due to the synchronizing effect of the ram. The first fertile estrus was observed 36 days (group A) and 45 days (group B) after the treatment. In group A all 10 animals and in groups B and C 8 of 9 ewes each became pregnant. Parenteral progestagen application with CAP and MPA is a simple, safe and reversible method of estrus suppression in the sheep. The minimal suppressive duration of 4 (CAP) and 5 weeks (MPA) is not sufficient when a period of 3 months (alpine pasture period) is desired.

    Use of dispersive clay as construction material requires treatment such as by chemical addition. Treatments to dispersive clay using pozzolan and Portland cement, singly and simultaneously, were carried out in this study. When used alone, the optimum amount of pozzolan required to treat a fully dispersive clay sample was 5%, but the curing time to reduce dispersion potential, from 100% to 30% or less, was 3 month long. On the other hand, also when used alone, a 3% cement content was capable of reducing dispersion potential to almost zero percent in only 7 days; and a 2% cement content was capable of achieving similar result in 14 days. However, treatment by cement alone is costly and could jeopardize the long term performance. Thus, a combined 5% pozzolan and 1.5% cement content was found capable of reducing dispersion potential from 100% to zero percent in 14 days. The results indicate that although simultaneous treatment with pozzolan and cement would extend the required curing time in comparison to treatment by cement alone of a higher content, the task could still be carried out in a reasonable period of curing time while avoiding the drawbacks of using either pozzolan or cement alone.

    The aim of this study was to determine the therapeutic success of the medical treatment of canine pyometra with the antigestagen aglepristone and to document the recurrence rate in relation to the time interval after treatment with antigestagens. In 48 (92.8%) of the 52 treated bitches, healing could be achieved within the first 3 weeks after the treatment had been started. One bitch died as a result of renal insufficiency; in three bitches there was no emptying of the uterus, so ovariohysterectomy became necessary. In these three patients, ovarian and endometrial cysts were present. Forty-one bitches could be followed up for 3 months. Four animals developed a recurrence (9.8%). In three bitches ovarian cysts and cystic endometrial hyperlasia could be found intra operationem. The development of 37 bitches could be followed for at least 1 year. Seven animals developed a pyometra again (18.9%). Two received a repeated treatment with aglepristone and have been free from recurrence for over 12 months. In 37 animals data on the subsequent sex cycles are available. In 22 bitches next heat started at the expected time, in seven animals heat started too early. In eight bitches the period of anoestrus was prolonged. Five of the six bred bitches delivered at least one litter. The presented data show that treatment of pyometra by aglepristone results in a high healing rate. The recurrence rate can be minimized by the selection of bitches without ovarian cysts and cystic endometrial hyperplasia. PMID:14633233

    Background and Purpose: Endovascular treatment of unruptured posterior circulation intracranial aneurysms (UPCIAs) is limited in the International Study of Unruptured Intracranial Aneurysms (ISUIA). The aim of this study is to evaluate the periprocedural morbidity, mortality, and midterm clinical and angiographic follow-ups of endovascular treatment of UPCIAs. Materials and Methods: Retrospective analysis of all patients treated in a 2-year period (89 patients: 10–78 years of age, mean: 45.5 ± 14.3/92 UPCIAs). Fifty-eight aneurysms were found incidentally, 12 in association with mass effect symptoms and 22 with stroke. Results: A clinical improvement or stable outcome was achieved in 84 patients (94.4%). The two cases of permanent morbidity included a patient with paralysis and another patient with hemianopia. One patient died after treatment of a giant fusiform vertebrobasilar aneurysm. In one patient, the aneurysm ruptured during treatment, resulting in death. Another patient suffered a fatal aneurysm rupture 4 days after treatment. Giant size (P = 0.005) and mass effect presentation (P = 0.029) were independent predictors of unfavorable outcomes in UPCIAs. Angiographic follow-up was available in 76 of the 86 surviving patients (88.4%) with a mean of 6.8 months (range: 1–36 months). Recanalization in six patients (7.9%) at 3 months, 4 months, 4 months, 24 months, and 36 months required retreatment in three patients. In-stent stenosis of >50% was found in three patients. Conclusion: Endovascular therapy is an attractive option for UPCIAs with stable midterm outcome. However, the current endovascular option seems to have a limitation for the treatment of the aneurysm with giant size or mass effect presentation. PMID:27570378

  10. Attention Reorients Periodically.

    Reorienting of voluntary attention enables the processing of stimuli at previously unattended locations. Although studies have identified a ventral fronto-parietal network underlying attention [1, 2], little is known about whether and how early visual areas are involved in involuntary [3, 4] and even less in voluntary [5] reorienting, and their temporal dynamics are unknown. We used transcranial magnetic stimulation (TMS) over the occipital cortex to interfere with attentional reorienting and study its role and temporal dynamics in this process. Human observers performed an orientation discrimination task, with either valid or invalid attention cueing, across a range of stimulus contrasts. Valid cueing induced a behavioral response gain increase, higher asymptotic performance for attended than unattended locations. During subsequent TMS sessions, observers performed the same task, with high stimulus contrast. Based on phosphene mapping, TMS double pulses were applied at one of various delays to a consistent brain location in retinotopic areas (V1/V2), corresponding to the evoked signal of the target or distractor, in a valid or invalid trial. Thus, the stimulation was identical for the four experimental conditions (valid/invalid cue condition × target/distractor-stimulated). TMS modulation of the target and distractor were both periodic (5 Hz, theta) and out of phase with respect to each other in invalid trials only, when attention had to be disengaged from the distractor and reoriented to the target location. Reorientation of voluntary attention periodically involves V1/V2 at the theta frequency. These results suggest that TMS probes theta phase-reset by attentional reorienting and help link periodic sampling in time and attention reorienting in space.

    Geyser eruption frequency is not constant over time and has been shown to vary with small (???10-6) strains induced by seismic events, atmospheric loading, and Earth tides. The geyser system is approximated as a permeable conduit of intensely fractured rock surrounded by a less permeable rock matrix. Numerical simulation of this conceptual model yields a set of parameters that controls geyser existence and periodicity. Much of the responsiveness to remote seismicity and other small strains in the Earth can be explained in terms of variations in permeability and lateral recharge rates.

    Postanesthetic complications can occur even in the best of circumstances. Proper preparation of the staff, aggressive monitoring of the recovering patient, and early recognition and management of the complications are essential if the outcome is to be successful. In reviewing postanesthetic complications, two factors are present in the overwhelming majority of situations--hypoxia and hypercarbia--often the direct result of inadequate monitoring during the postanesthetic period. The anesthetic procedure is not over once the anesthetic agents are discontinued. The skillful anesthetist is aware of the possibilities of postoperative complications and prevents problems by employing enhanced monitoring techniques during the recovery phase.

    The present clinical study investigated the outcome of intentional replantation using resection of the ankylosed sites of the root, extraoral endodontic treatment using titanium posts and Emdogain for periodontal healing following trauma-related ankylosis. During an evaluation period of 6 years, 16 ankylosed teeth affected by replacement resorption were treated as described. Evaluation parameters before treatment and during the follow-up period included Periotest scores, percussion sound and periapical radiographs. All findings were compared to those of the adjacent teeth. In a second accident, one tooth was lost after 7 months and was excluded as a dropout. Ankylosis did not recur in seven replanted teeth, which were observed for an average of 52.3 months (range: 24-68 months). Ankylosis recurred in eight teeth after an average period of 12 months (range: 4-26 months). An infraocclusion, normal or only slightly reduced Periotest scores and normal percussion sound were preoperatively found in six of seven successfully replanted teeth, which corresponded to a relatively small area of ankylosis. The majority of the teeth showing recurrent ankylosis preoperatively presented with normal position, negative Periotest scores and a high percussion sound which corresponded to an extended area of ankylosis. Statistically significant relationship between preoperative findings and the treatment outcome (P = 0.031) have become apparent. The results indicate that the treatment of minor areas of ankylosis by intentional replantation, resection of the ankylosed sites and Emdogain appeared to prevent or delay the recurrence of ankylosis in 7 of 15 teeth.

Upon initial assessment, he presented with a positive open-can test, lift-off test, and Hawkins-Kennedy impingement test. A MDT assessment quickly ruled out cervical involvement and identified a loss of end-range shoulder mobility and pain during active shoulder movement. After the patient underwent a repeated movement examination and treatment based on responses to end-range movements over three visits, his shoulder pain was abolished and motion was fully restored. Despite having positive rotator cuff and impingement signs, this patient was effectively treated with repeated end-range movements over a short period of 2 weeks. This case demonstrates that treatment based on MDT sub-classification principles may be an effective way to manage shoulder pain as it is in the spine.

    Objectives To evaluate paliperidone palmitate (PP) effectiveness, safety and adherence to treatment. Methods We collected data of all patients (n = 50) affected by Schizophrenia Disorders, treated with PP for a 3 month minimum period in the outpatient setting of Mental Health Department in Modena, from 01/01/2014 to 31/01/2015. We evaluated reasons and modality for PP implementation, improvement in symptom and functioning scales, adverse effects, discontinuations and relapses. We statistically correlated socio-demographic and clinical variables of our sample with PP therapeutic variables. Results We registered an improvement in all scales, with a superior percentage in PANSS positive subscale. The mean PP dose in some patients was lower than official indications, although our sample was clinically severe. Illness relapses affected 60% and dropout 18% of patients. PP was well tolerated and in just a few cases adverse events required treatment interruption. The risk factors for discontinuation were represented by “lack of therapeutic compliance” (HR = 4.11, p < 0.0001) and “inefficacy” (HR = 1.67, p < 0.0001). Conclusions With limitations of observational design, this research highlights that PP was well tolerated and effective in improving both psychotic symptoms and functioning, but moderately effective in preventing relapse, probably due to clinical severity of our patients associated with extremely cautious and flexible PP prescriptions.

    Benign prostatic hyperplasia (BPH)is the most common condition in aging men, associated with lower urinary tract symptoms. It is caused due to the augmented levels of the androgen dihydrotestosterone. Dutasteride, a 5α-Reductase inhibitor has been recommended for the treatment of BPH upon oral administration. However, long term oral administration of dutasteride may cause sexual problem in man. Therefore the main objective of this study was to develop transdermal patch having nanoemulsion gel of dutasteride in order to enhance physical and chemical stability and eliminate adverse effect of dutasteride. Optimized nanoemulsion was prepared by aqueous phase-titration method and characterized by droplet size, viscosity and refractive index. In-vitro skin permeation of dutasteride through rat abdominal skin was determined by the Franz diffusion cell.Significant increase in the steady state flux (Jss), permeability coefficient (Kp) and enhancement ratio (Er) was observed in optimized nanoemulsion formulation A1 (p < 0.05). The Er of optimized nanoemulsion A1 was found to be 1.52 times with respect to control which indicates transdermal delivery may be better approach for BPH. Stability studies were performed for the period of 3 months. It was found that droplet size, viscosity and refractive index were slightly increased at refrigerator and room temperature in 3 months period. However, the changes in these parameters were not statistically significant (p ≥ 0.05). The shelf-life of optimized nanoemulsion A1 was found to be 2.18 years at room temperature. These results indicated that both physical as well as chemical stability of dutasteride in nanoemulsion formulation. PMID:25587300

    The antihypertensive efficacy and acceptability of perindopril (P) were compared to those of captopril (C), atenolol (A) and a diuretic, hydrochlorothiazide + amiloride (D), in 3 double-blind parallel multicenter studies involving 165, 173, and 165 patients, respectively. Patients with essential hypertension and a supine DBP between 95 and 125 mmHg (mean 103.9, 106.2, and 105.2 mmHg, respectively) after a 1-month placebo period were randomized to P 4 mg once daily (o.d.) and either C 25 mg twice daily, or A 50 mg o.d. or D (hydrochlorothiazide 50 mg + amiloride 5 mg o.d.) and treated for 3 months, with visits at monthly intervals. If necessary, treatment was adjusted at each visit to control BP (supine DBP less than or equal to 90 mm Hg): firstly by doubling the dose and secondly, one month later, by the addition of a second drug, a diuretic in the studies versus C or A, a beta-blocker in the study versus D. At 3 months, BP control on monotherapy in the three studies was achieved in the following proportion of patients: 49% with P vs 49% with C; 55% with P vs 48% with A; 72% with P vs 72% with D. Most of the patients controlled by P received 4 mg, about 15% were controlled with 8 mg. A further percentage of patients was controlled with combination therapy, the combination with a diuretic being more effective with P than with C (26 vs 8%) or A (23 vs 10%) and the combination with a beta-blocker being less effective with P than with D (5 vs 13%). The total percentage of patients controlled was greater with P than with C (75 vs 57%, p = 0.016) or A (78 vs 58%, p = 0.006) and there was no significant difference between P and D (78 vs 84%). The drop-out rate due to side-effects was up to 6% with P, similar to that observed with C (4%), A (5%) and D (5%). Most of the complaints reported with P were minor and non-specific, their incidence being similar to that observed with the other drugs. Cough was reported with both P (1%) and C (2%) as well as with A (1%) and D (1

    Purpose. We evaluated promising new treatment options for strabismus. Neurotrophic factors have emerged as a potential treatment for oculomotor disorders because of diverse roles in signaling to muscles and motor neurons. Unilateral treatment with sustained release brain-derived neurotrophic factor (BDNF) to a single lateral rectus muscle in infant monkeys was performed to test the hypothesis that strabismus would develop in correlation with extraocular muscle (EOM) changes during the critical period for development of binocularity. Methods. The lateral rectus muscles of one eye in two infant macaques were treated with sustained delivery of BDNF for 3 months. Eye alignment was assessed using standard photographic methods. Muscle specimens were analyzed to examine the effects of BDNF on the density, morphology, and size of neuromuscular junctions, as well as myofiber size. Counts were compared to age-matched controls. Results. No change in eye alignment occurred with BDNF treatment. Compared to control muscle, neuromuscular junctions on myofibers expressing slow myosins had a larger area. Myofibers expressing slow myosin had larger diameters, and the percentage of myofibers expressing slow myosins increased in the proximal end of the muscle. Expression of BDNF was examined in control EOM, and observed to have strongest immunoreactivity outside the endplate zone. Conclusions. We hypothesize that the oculomotor system adapted to sustained BDNF treatment to preserve normal alignment. Our results suggest that BDNF treatment preferentially altered myofibers expressing slow myosins. This implicates BDNF signaling as influencing the slow twitch properties of EOM. PMID:26030102

    Hemorrhoidal disease is particularly frequent in the last trimester of pregnancy and immediately after birth. The aim of the present study was to evaluate the efficacy and tolerability of high doses of O-(beta-hydroxyethyl)-rutoside in patients affected by this pathology. Forty-two women with hemorrhoid varices of varying severity which had appeared during the last trimester of pregnancy or immediately post-partum were treated by administering 3 g/day of the substance in question for 14 consecutive days. At the start and end of treatment a series of clinical and objective parameters were measured and at the end of treatment efficacy and tolerability were assessed. The latter was found to be excellent; in fact, it was not necessary to suspend treatment in any of the subjects treated. Clinical efficacy, assessed by the researcher, was judged to be positive in 95% of cases treated. Clinical improvements in the parameters examined were statistically significant (p < 0.01). The results obtained confirm the value of oral therapy using O-(beta-hydroxyethyl)-rutoside in pregnant or puerperal patients since the preparation was found to be efficacious and easily managed, above all significantly reducing pain, subjectively the most urgent symptom to be treated.

    We show the existence of periodic exploding dissipative solitons. These non-chaotic explosions appear when higher-order nonlinear and dispersive effects are added to the complex cubic-quintic Ginzburg-Landau equation modelling soliton transmission lines. This counterintuitive phenomenon is the result of period-halving bifurcations leading to order (periodic explosions), followed by period-doubling bifurcations (or intermittency) leading to chaos (non-periodic explosions).

    Treatments targeting metabolic abnormalities in children with autism are limited. Previously we reported that a nutritional treatment significantly improved glutathione metabolism in children with autistic disorder. In this study we evaluated changes in adaptive behaviors in this cohort and determined whether such changes are related to changes in glutathione metabolism. Thirty-seven children diagnosed with autistic disorder and abnormal glutathione and methylation metabolism were treated with twice weekly 75 µg/Kg methylcobalamin and twice daily 400 µg folinic acid for 3 months in an open-label fashion. The Vineland Adaptive Behavior Scale (VABS) and glutathione redox metabolites were measured at baseline and at the end of the treatment period. Over the treatment period, all VABS subscales significantly improved with an average effect size of 0.59, and an average improvement in skills of 7.7 months. A greater improvement in glutathione redox status was associated with a greater improvement in expressive communication, personal and domestic daily living skills, and interpersonal, play-leisure, and coping social skills. Age, gender, and history of regression did not influence treatment response. The significant behavioral improvements observed and the relationship between these improvements to glutathione redox status suggest that nutritional interventions targeting redox metabolism may benefit some children with autism.

    A new and previously unpublished thermodynamic treatment device, which for the first time applies heat directly to both inner eyelid surfaces with a precision-controlled resistive heater while pulsating pressure is simultaneously applied to the outer eyelids using an inflatable air bladder, was used to restore meibomian gland functionality for a subject with severe evaporative dry eye. The subject, a 39-year-old white woman of light complexion with severe symptoms and corroborating objective signs of dry eye, had been unsuccessfully treated for 3 years by 7 practitioners. Using a new standardized meibomian gland expression device, a diagnosis of nonobvious meibomian gland dysfunction, where none of the approximately 24 meibomian glands of the right lower eyelid and 1 meibomian gland of the left lower eyelid were functional, was made. The patient underwent a single 12-minute treatment per eye with the treatment device. The treatment restored the functionality of 8 glands in each eye, doubled the fluorescein break-up time (FBUT) from 5 to 10 seconds, and decreased the symptom scores by approximately 80% for the entire follow-up period of 3 months.

    Purpose: The purpose of this study is to evaluate the effectiveness of chronic suppurative lacrimal canaliculitis treatment using chalazion forceps. Patients and Methods: A prospective study was performed on consecutive patients who accepted the aid of chalazion forceps to treat chronic suppurative lacrimal canaliculitis. Two different treatment methods using chalazion forceps were performed according to the degree of lacrimal canaliculitis. Postoperatively, the patients received 0.5% levofloxacin eye drops four times per day and 0.5 g oral levofloxacin tablets once per day for 4 days. The follow-up period was more than 3 months. Lacrimal irrigation, the condition of the lacrimal punctum, and patients’ symptoms were carefully evaluated. Results: In total, 32 patients met the criteria for chronic suppurative lacrimal canaliculitis. Included were 6 males and 26 females. Their average age was 51.7 ± 14.9 years (range; 19–80 years), and all had unilateral canaliculitis. The mean duration of the symptoms was 18.9 ± 9.8 months (range; 3–48 months). The mean follow-up time was 14.7 ± 7.8 months. The signs and symptoms resolved completely in all patients within 15 days, and no recurrence was observed. No patients reported epiphora after the treatment. Conclusions: The use of chalazion forceps is effective in treating chronic suppurative lacrimal canaliculitis. The forceps may offer an alternative treatment technology in the management of suppurative lacrimal canaliculitis. PMID:27688281

    Purpose: To present four cases of penetrating ulcer of the descending thoracic aorta treated by transfemoral insertion of an endoluminal stent-graft. Methods: Four patients with penetrating aortic ulcers were reviewed. Three cases were complicated by rupture, false aneurysm, or retrograde dissection. All patients were treated by endovascular stent-graft and were followed by helical computed tomography (CT). Results: Endovascular stent-graft deployment was successful in all patients. However, in one case we observed a perigraft leak that spontaneously disappeared within the first month, and two interventions were needed for another patient. Following treatment, one episode of transient spinal ischemia was observed. The 30-day survival rate was 100%, but one patient died from pneumonia with cardiac failure 34 days after the procedure. In one patient, helical CT performed at 3 months showed a false aneurysm independent of the first ulcer. This patient refused any further treatment and suddenly died at home (unknown cause) after a 6-month follow-up period. Conclusion: Transluminal placement of endovascular stent-grafts for treatment of penetrating ulcers of the descending thoracic aorta appears to be a possible alternative to classical surgery. After treatment, follow-up by CT is essential to detect possible complications of the disease.

    The periodically oscillating plasma sphere, or POPS, is a novel fusion concept first proposed by D. C. Barnes and R. A. Nebel [Fusion Technol. 38, 28 (1998)]. POPS utilizes the self-similar collapse of an oscillating ion cloud in a spherical harmonic oscillator potential well formed by electron injection. Once the ions have been phase-locked, their coherent motion simultaneously produces very high densities and temperatures during the collapse phase of the oscillation. A requirement for POPS is that the electron injection produces a stable harmonic oscillator potential. This has been demonstrated in a gridded inertial electrostatic confinement device and verified by particle simulation. Also, the POPS oscillation has been confirmed experimentally through observation that the ions in the potential well exhibit resonance behavior when driven at the POPS frequency. Excellent agreement between the observed POPS frequencies and the theoretical predictions has been observed for a wide range of potential well depths and three different ion species. Practical applications of POPS require large plasma compressions. These large compressions have been observed in particle simulations, although space charge neutralization remains a major issue.

    Bibliometry or the science citation index is a quantitative evaluation of periodical literature, biomedical or others. It depends above all on an analysis of citations which allows for a calculation of different indices characterising and classifying journals (number of articles published, frequency of citation, impact, topicality...). The applications of bibliometry are varied from the administration of library collections to the appreciation of the significance of a review in its own speciality area. By extension the bibliometry index are sometimes used to evaluate the importance of a discipline in the literature, the place of a nation within a discipline, the significance of certain opinions or the quality of research. The intrinsic limits of bibliometry are such that this last application should be handled with caution. In effect, various biases can mechanically affect the value of different indices and particularly the fact that an article appearing in a prestigious review should not prejudge its quality such as the relevance of the question posed, the validity of the methodology employed or the accuracy of the results. For this, the study of citations is insufficient and some qualitative or semi-quantitative criteria bearing on the contents of the article should be used (critical reading, gate analysis, etc.) This general review has, as its aim, to expose both the definitions and limits of bibliometry illustrating them with some information calculated from the principal respiratory journals.

    Background and aims Muscular pain in the facial region is the most common cause of facial pains. Myofascial pain dysfunction syndrome (MPDS) is one of the most important facial muscle disorders comprising of signs and symptoms including pain during function, tenderness in the muscles of mastication and restricted jaw movement. Due to the lack of an accepted therapeutic approach, the purpose of this paper was to find an effective treatment to decrease the pain of such patients. Considering the analgesic and anti-inflammatory action of laser therapy, the effects of low level laser (Ga-Al-As) in the treatment of MPDS patients referred to Tehran University of Medical Sciences Faculty of Dentistry, were investigated in the present study. Materials and methods This study was a quasi-experimental research. Twenty-two MPDS patients were selected from those referred to Department of Oral Medicine, Tehran University of Medical Sciences Faculty of Dentistry. Clinical examination was performed at six stages in the following order: prior to the treatment, at 2 and 4 weeks after treatment, and monthly thereafter for a 3-months follow-up. All patients underwent low-level laser therapy for 4 weeks (12 sessions). Variables such as pain severity, pain of cheek region, pain frequency, tenderness of masticatory muscles, click, and mouth opening were evaluated at each stage. Numerical variables were investigated using Analysis of Variance test for repeated measures whereas ranking variables were studied by non-parametric Kruskal-Wallis test. Results At the end of treatment period, pain severity, pain of cheek region, pain frequency, tenderness of masseter, temporalis, medial pterygoid, and lateral pterygoid muscles showed significant improvement as compared with the commencement of any treatment which continued during the 3-months post-treatment (p<0.05). Conclusion It was shown that low-level laser (Ga-Al-As) therapy had the efficacy to alleviate pain and decrease the tenderness of

    Pilonidal sinus is a cystic disease that occurs most often in the sacrococcygeal region. Surgical excision and coverage with a skin flap require postoperative bed rest. Most affected patients are young adults who find it difficult to obtain adequate postoperative bed rest owing to their work. The purpose of this study is to review the effectiveness of our ambulatory surgery procedure for pilonidal sinus, which involves tract excision and open treatment followed by at-home irrigation. We reviewed the 9 cases of chronic pilonidal sinus treated at our out-patient clinic by ambulatory surgery consisting of open excision without skin closure. Patients were sent home after careful observation for hemostasis at the surgical site. Postoperative wound treatment and irrigation were performed at home by the patients themselves. The mean immediate postoperative follow-up period was 22.3 days (13 to 31 days), and the mean number of follow-up visits was 3.3. No serious complication and recurrence was noted during the long-term follow-up period of 26.3 months (1 to 60 months). Although the healing time following our ambulatory procedure was not short, no postoperative rest was required, and the recurrence rate was zero. We believe this procedure is useful for selected patients with pilonidal sinus. J. Med. Invest. 63: 216-218, August, 2016. PMID:27644561

    The widespread drought suffered by the Amazon rain forest in the summer of 2005 was heralded at the time as the drought of the century. Because of the dehydrated conditions, supplemented by slash and burn agricultural practices, the drought led to widespread forest fires throughout the western Amazon, a portion of the rain forest usually too lush to support spreading wildfires. Only 5 years later, the 2005 season was outdone by even more widespread drought, with fires decimating more than 3000 square kilometers of western Amazonian rain forest. Blame for the wildfires has been consistently laid on deforestation and agricultural practices, but a convincing climatological explanation exists as well.

    Purpose. Unilateral treatment with sustained release IGF-1 to one medial rectus muscle in infant monkeys was performed to test the hypothesis that strabismus would develop as a result of changes in extraocular muscles during the critical period of development of binocularity. Methods. Sustained release IGF-1 pellets were implanted unilaterally on one medial rectus muscle in normal infant monkeys during the first 2 weeks of life. Eye position was monitored using standard photographic methods. After 3 months of treatment, myofiber and neuromuscular size, myosin composition, and innervation density were quantified in all rectus muscles and compared to those in age-matched controls. Results. Sustained unilateral IGF-1 treatments resulted in strabismus for all treated subjects; 3 of the 4 subjects had a clinically significant strabismus of more than 10°. Both the treated medial rectus and the untreated ipsilateral antagonist lateral rectus muscles had significantly larger myofibers. No adaptation in myofiber size occurred in the contralateral functionally yoked lateral rectus or in myosin composition, neuromuscular junction size, or nerve density. Conclusions. Sustained unilateral IGF-1 treatment to extraocular muscles during the sensitive period of development of orthotropic eye alignment and binocularity was sufficient to disturb ocular motor development, resulting in strabismus in infant monkeys. This could be due to altering fusion of gaze during the early sensitive period. Serial measurements of eye alignment suggested the IGF-1-treated infants received insufficient coordinated binocular experience, preventing the establishment of normal eye alignment. Our results uniquely suggest that abnormal signaling by the extraocular muscles may be a cause of strabismus. PMID:26030103

    This study compared two treatments for mild noncarious cervical lesions (NCCLs): a subepithelial connective tissue graft (CTG) versus a Class V composite resin restoration (CRR). Twenty-six sites with NCCLs were randomly assigned to be treated by CTG or CRR. Periodontal health parameters and dentinal hypersensitivity (DH) were recorded at baseline and 3 months postoperatively. Esthetics was also evaluated at 3 months. Results showed a significant improvement in all periodontal health parameters in the CTG treatment. The CTG treatment attained a mean 82% defect coverage with 75% of sites achieving complete coverage. Patients rated the CTG treatment to be significantly more esthetic (P = .03), while a clinician panel did not see an esthetic difference (P = .86). There was no difference in DH reduction between the two treatments (P = .81). In conclusion, the CTG treatment is superior to the CRR treatment for NCCLs based on periodontal health parameters. From a patient point of view, the CTG is the more esthetic treatment.

    Cholestasis results from impairment in the excretion of bile, which may be due to mechanical obstruction of bile flow or impairment of excretion of bile components into the bile canaliculus. When present, cholestasis warrants prompt diagnosis and treatment. The differential diagnosis of cholestasis beyond the neonatal period is broad and includes congenital and acquired etiologies. It is imperative that the clinician differentiates between intrahepatic and extrahepatic origin of cholestasis. Treatment may be supportive or curative and depends on the etiology. Recent literature shows that optimal nutritional and medical support also plays an integral role in the management of pediatric patients with chronic cholestasis. This review will provide a broad overview of the pathophysiology, diagnostic approach, and management of cholestasis beyond the neonatal and infancy periods. PMID:27066444

    2000-01-01

    An attempt was made to pharmaceutically develop a topical liposomal tretinoin (TRE) gel and clinically evaluate the developed formulation for the treatment of acne in patients. Liposomes of TRE were prepared using the lipid film hydration technique and the entrapment efficiency of TRE in liposomes was optimized to 79.96%. The drug retention in liposomes and in liposomal TRE gel (Carbopol 934 gel base) studied at three storage conditions indicated maximum drug retention at refrigeration temperature. For liposomal TRE gel, reduced drug leakage was observed as compared to that of liposomes at all three storage conditions. Diffusion studies of plain TRE gel and liposomal TRE gel suggested prolongation (3.4 times reduction in flux value) of drug diffusion and almost two-fold increase in skin drug retention after liposomal encapsulation of drug. A comparative double-blind clinical study of the developed liposomal TRE gel, carried out on 30 acne patients over a period of 3 months, demonstrated significant enhancement (about 1.5-fold) in drug efficacy. More remarkable improvement was observed in the treatment of comedones, where the mean percent reduction in lesions increased from 62.36% for plain TRE gel to 94.17% for liposomal TRE gel. Erythema and irritation associated with the use of plain TRE gel was reduced considerably with the use of liposomal TRE gel. The findings of this investigation therefore underscore potential utility of commercialization of liposomal TRE gel in the treatment of acne. PMID:11109245

    Opioid dependence (OD), often characterized as a chronic relapsing disorder, affects millions of people worldwide. The purpose of this study was to examine the effect of compliance with buprenorphine on reducing relapse among a sample of patients in treatment for OD. Patients new to buprenorphine (N = 703) completed the Addiction Severity Index (ASI) at baseline, and at 1, 2, and 3 months postbaseline. The ASI is a semistructured interview designed to measure problem severity in seven functional areas known to be affected by alcohol and drug dependence. Compliance was defined as taking buprenorphine medication on at least 22 of the past 28 days (80%), while relapse classification was based on resumed use of opioids during the follow-up period (months 2 and 3). Relapse was regressed onto demographic indicators, baseline ASI composite scores, and compliance with buprenorphine. Noncompliant patients were over 10 times more likely to relapse than those who were compliant (exp β= 10.55; p < .001). Neither demographics nor baseline ASI composite scores were predictive of relapse (p's > .05). Compliance with medication-assisted treatment supports abstinence, essential for patient recovery. Understanding the factors that drive treatment compliance and noncompliance may assist providers in supporting patient compliance and recovery.

    2001-11-01

    The objectives of this research were to investigate the potential to biologically treat volatile organic compounds emitted by the forest products industry at thermophilic conditions and to examine the microbial community developed at high temperatures. Three biotrickling filters were run in parallel at temperatures ranging from 40 degrees C (mesophilic control) to 70 degrees C. The first phase involved treatment of methanol, for a 3-month run, and the second phase involved a 260-day run on the treatment of alpha-pinene. Methanol removal rates over 100 g m(-3) h(-1) where achieved at temperatures up to 70 degrees C. Alpha-pinene removal was achieved at temperatures up to 60 degrees C with optimal treatment occurring at 55 degrees C at rates up to 60 g m(-3) h(-1). The time for acclimation increased with increasing temperature and was longer for pinene than for methanol. Filter performance was also able to quickly recover from a shutdown period of up to 2 weeks due to the robustness of the microbial communities as determined by DNA fingerprinting analysis. The high-temperature communities treating methanol or pinene were more similar to each other than the mesophilic communities (i.e., 40 degrees C). The mesophilic methanol community had a high degree of functional redundancy, while the mesophilic pinene community was more unique and very distinct from the others. These results show that biofiltration at high temperatures is achievable and opens up a range of possibilities for applying biofiltration to hot gas streams.

    This study examined retention rates and associated predictors of methadone maintenance treatment (MMT) duration among 128 newly admitted patients in Taiwan. A semi-structured questionnaire was used to obtain demographic and drug use history. Daily records of methadone taken and test results for HIV, HCV, and morphine toxicology were taken from a computerized medical registry. Cox regression analyses were performed to examine factors associated with MMT duration. MMT retention rates were 80.5%, 68.8%, 53.9%, and 41.4% for 3, 6, 12, and 18 months, respectively. Excluding 38 patients incarcerated during the study period, retention rates were 81.1%, 73.3%, 61.1%, and 48.9% for 3 months, 6 months, 12 months, and 18 months, respectively. No participant seroconverted to HIV and 1 died during the 18-months follow-up. Results showed that being female, imprisonment, a longer distance from house to clinic, having a lower methadone dose after 30 days, being HCV positive, and in the New Taipei city program predicted early patient dropout. The findings suggest favorable MMT outcomes of HIV seroincidence and mortality. Results indicate that the need to minimize travel distance and to provide programs that meet women’s requirements justify expansion of MMT clinics in Taiwan. PMID:25875531

  9. Evolutionary ecology of periodical insects.

    PubMed

    Heliövaara, K; Väisänen, R; Simon, C

    1994-12-01

    To be periodical, a species must have a fixed life cycle length and adults must appear synchronously, reproduce only once, and die. The consequence of this life history is that, at a given location, adults of a periodical species will be absent or rare in some years and abundant in others. The relative scarcity of periodical Insect species suggests that periodicity does not evolve easily. The major obstacle to its evolution is selection favoring life cycles In which the offspring of any given female appear over a two- or three-year period. Chance events which disrupt this 'bet-hedging' strategy set the stage for periodicity. Mathematical models predict that, given certain initial conditions, intraspecific competition and predation favor its development. Recent studies suggest that periodicity is rarely perfect but that it can persist in the face of limited gene flow through time.

    Abstract This cross-sectional study aimed to determine the prevalence and impact of depression on health care costs in patients with complex chronic pain. The sample included 1204 patients attending a tertiary pain management service for people with chronic disabling pain, unresponsive to medical treatment. As part of routine care, patients completed a web-based questionnaire assessing mental and physical health, functioning, and service use in the preceding 3 months. Depression was assessed using the 9-item Patient Health Questionnaire. Self-report health care utilisation was measured across 4 domains: general practitioner contacts, contacts with secondary/tertiary care doctors, accident and emergency department visits, and days hospitalised. The participation rate was 89%. Seven hundred and thirty-two patients (60.8%; 95% CI 58.0-63.6) met criteria for probable depression, and 407 (33.8%) met the threshold for severe depression. Patients with depression were more likely to be unable to work because of ill health and reported greater work absence, greater pain-related interference with functioning, lower pain acceptance, and more generalised pain. Mean total health care costs per 3-month period were £731 (95% CI £646-£817) for patients with depression, compared with £448 (95% CI £366-£530) for patients without depression. A positive association between severe depression and total health care costs persisted after controlling for key demographic, functional, and clinical covariates using multiple linear regression models. These findings reveal the extent, severity, and impact of depression in patients with chronic pain and make evident a need for action. Effective treatment of depression may improve patient health and functioning and reduce the burden of chronic pain on health care services. PMID:26963849

    In this Letter, for a general class of delayed periodic Lotka-Volterra systems, we prove some new results on the existence of positive periodic solutions by Schauder's fixed point theorem. The global asymptotical stability of positive periodic solutions is discussed further, and conditions for exponential convergence are given. The conditions we obtained are weaker than the previously known ones and can be easily reduced to several special cases.

    We investigate the generation of fractional-period states in continuum periodic systems. As an example, we consider a Bose-Einstein condensate confined in an optical-lattice potential. We show that when the potential is turned on nonadiabatically, the system explores a number of transient states whose periodicity is a fraction of that of the lattice. We illustrate the origin of fractional-period states analytically by treating them as resonant states of a parametrically forced Duffing oscillator and discuss their transient nature and potential observability.

    2008-09-01

    Overland flow (OF) systems were evaluated and compared for advanced treatment of municipal and industrial effluents, including nutrients and nondegradable chemical oxygen demand (COD) removal. Three pilot plants were constructed at the Shahin Shahr Wastewater Treatment Plant (WWTP), Isfahan, Iran. Each pilot was assigned a specific wastewater and all were simultaneously operated for 8 months. Treatment of primary effluent, activated sludge secondary effluent, and lagoon effluent of textile wastewater was investigated at application rates (ARs) of 0.15, 0.25, and 0.35 m(3)m(-1)h(-1). During 5 months of stable operation after a 3-month acclimation period, mean removals of total 5-day biochemical oxygen demand (TBOD(5)), total COD (TCOD), total suspended solids (TSS), total nitrogen (TN), total phosphorus (TP) and turbidity were 74.5%, 54.8%, 66.2%, 39.4%, 35.8%, and 67.7% for primary effluent; 52.9%, 52.9%, 66.5%, 44.4%, 39.8%, and 50.1% for activated sludge effluent; 65.7%, 58.7%, 70.3%, 41.7%, 41.3%, and 54.9% for textile wastewater lagoon effluent, respectively. The model of Smith and Schroeder, 1985. Field studies of the overland flow process for the treatment of raw and primary treated municipal wastewater. Journal of Water Pollution Control Federation 57, 785-794] was satisfactory for TBOD(5). For all treatment parameters a standard first-order removal model was inadequate to represent the data but a modified first-order model provided a satisfactory fit to the data. Based on the results of this study, it can be concluded that an OF system as advanced treatment had the ability to meet effluent discharge permit limits and was an economical replacement for stabilization ponds and mechanical treatment options.

    This study assessed the role of static factors, a dynamic factor (motivation to change sexually deviant behavior), and an administrative factor in predicting treatment retention within a prison-based sex offender treatment program. The analyses also included assessing differences in initial levels of motivation and differences in beginning-versus end-of-treatment motivation scores for various types of program discharges. The sample consisted of 251 individuals who were admitted to a residential prison-based sex offender treatment program where 46% completed the program. Paired comparison t-tests showed higher motivation scores at the end of treatment only among treatment completers. Multivariate analyses showed that treatment retention was associated with higher initial motivation scores, higher levels of education and admission to treatment within 3 months of initial commitment to prison. Implications for motivational enhancement programming as well as for changes in admission criteria are discussed.

    Background: Lifa disease (frictional dermal melanosis) is a common dermatological problem. Full strength lactic acid has been proved to be effective and safe peeling agent in the treatment of melasma. Objective: To assess the effectiveness and the safety of lactic acid chemical peeling in the treatment of lifa disease. Materials and Methods: This open label therapeutic trial was conducted in Department of Dermatology in Najaf and Baghdad Teaching Hospitals, from March 2007-October 2008. Full strength lactic acid (92%, pH 3.5) was used as a peeling agent. The treatment sessions were done every 2 weeks until the desired response was achieved (but not more than 6 sessions). The response to therapy was evaluated by objective and subjective methods. All patients were followed monthly for 3 months after the last treatment session. Results: 52 patients with typical clinical features of lifa disease were included. All patients were slim with prominent bones and low body mass index, and gave history of using the lifa (washing agent) during bathing. The number of sessions ranged from 2-6 sessions. The pigmentation was improved in all patients as revealed by objective and subjective methods, and this response was statistically highly significant. No significant side effects were recorded in all treated patients. The improvement has been sustained without any obvious relapse throughout the follow-up period. Conclusion: Lactic acid peel is a new, non-costly mode of therapy in treating dermal melanosis in patients with lifa disease. PMID:23248362

    We have assessed the efficacy and safety of Escherichia coli extract (ECE; Uro-Vaxom®) which contains active immunostimulating fractions, in the prophylactic treatment of chronically recurrent cystitis. Forty-two patients with more than 2 episodes of cystitis in the proceeding 6 months were treated for 3 months with one capsule daily of ECE and observed for a further 6 months. The primary efficacy criterion was the number of episodes of recurrent cystitis during the 6 months after treatment compared to those during the 6 months before treatment. At the end of the 9-month trial, 34 patients (all women) were eligible for statistical analysis. Their mean age was 56.4 yr (range, 34-75 yr), and they had experienced recurrent urinary tract infections for 7.2±5.2 yr. The number of recurrences was significantly lower during the 6-month follow-up period than during the 6 months preceding the trial (0.35 vs. 4.26, P<0.001). During the follow-up, 28 (82.4%) patients had no recurrences and 4 (11.8%) had 1 each. In patients who relapsed, ECE alleviated cystitis symptoms, including painful voiding, frequency and urgency. There were no serious adverse events related to the study drug. Our study demonstrates the efficacy and safety of ECE in the prophylactic treatment of chronically recurrent cystitis. PMID:20191044

    White spot lesions are one of the concerns during the fixed orthodontic treatment. Thus, the aim of the present study was to evaluate the antimicrobial/anti-inflammatory effect of curcumin-photodynamic antimicrobial chemotherapy (c-PACT) and chlorhexidine varnish on the plaque accumulation and gingival bleeding in adolescents under fixed orthodontic treatment. A randomized clinical trial was performed with an initial number of 45 patients being distributed into three groups: group I-chlorhexidine varnish 2%, group II-placebo varnish, and group III-c-PACT (curcumin at 1.5 mg.mL(-1)) exposed to blue Light-emitting diode (LED) light at 450 nm (power density = 165 mW.cm(-2), fluency = 96 J.cm(-2), total dose = 150.7 J). The treatments were performed for four consecutive times with an interval of 1 week each. After the interventions, two calibrated examiners (Kappa value = 0.75) analyzed the dental plaque accumulation by plaque index (PI) and gingivitis condition by gingival bleeding index (GBI) with 1 and 3 months of follow-up after the treatments comprised a final sample of 35 patients. No significant difference was found to PI between the groups during baseline and 1-month period. Group III (1.52 ± 0.51) presented significance difference from group I (0.91 ± 0.75) and group II (1.03 ± 0.51) at 3 months of follow-up. In this same period, there was more plaque accumulation with significant statistical difference (P ≤ 0.05) in comparison to the other periods to all studied groups. There was a GBI reduction statistically significant to groups I and III at 1-month follow-up in comparison to other periods. No effect was verified to dental plaque accumulation after the photodynamic application mediated with curcumin activated with a blue LED light.

    2016-04-01

    We study the dynamics and the phase-space structures of Coulombic and self-gravitating versions of the classical one-dimensional three-body system with periodic boundary conditions. We demonstrate that such a three-body system may be reduced isomorphically to a spatially periodic system of a single particle experiencing a two-dimensional potential on a rhombic plane. For the case of both Coulombic and gravitational versions, exact expressions of the Hamiltonian have been derived in rhombic coordinates. We simulate the phase-space evolution through an event-driven algorithm that utilizes analytic solutions to the equations of motion. The simulation results show that the motion exhibits chaotic, quasiperiodic, and periodic behaviors in segmented regions of the phase space. While there is no evidence of global chaos in either the Coulombic or the gravitational system, the former exhibits a transition from a completely nonchaotic phase space at low energies to a mixed behavior. Gradual yet striking transitions from mild to intense chaos are indicated with changing energy, a behavior that differentiates the spatially periodic systems studied in this Rapid Communication from the well-understood free-boundary versions of the three-body problem. Our treatment of the three-body systems opens avenues for analysis of the dynamical properties exhibited by spatially periodic versions of various classes of systems studied in plasma and gravitational physics as well as in cosmology.

    The purpose of this study was to evaluate the safety and validity of the treatment of uterine fibroids with HIFU. Materials and methods: 180 cases with uterine fibroid tumors (253 tumors) were treated; the patients were between 27 and 50 years old. HIFUNIT9000 was used to treat the tumors. Fibroid volume, local symptoms were measured before treatment and 3 months after treatment. Results: (i) Changes of clinical symptoms post treatment: among the 109 cases with increased menstrual flow or prolonged menstrual phase, 66 cases (60%) showed obvious improvement within one month after HIFU treatment and 83 cases (76%) within 3 months, the number of the cases rose to 98(90%) in 6 months. (ii) Fibroid volume pre and post treatment: 196 tumors (77%) reduced their volume by over 40%, among which some 1/3 further reduced through B-mode ultrasound examination 3 months after HIFU treatment. (iii) Pain and the changes of skin during or post treatment: a few (21/180) felt moderate pain of skin that was relieved after adjustment of thermal dosage and no long-lasting intensive pain occurred during the HIFU treatment. Degree I burn of local skin occurred in 6 cases (3.3%) and all recovered in 3 to 5 days. (iv) Nerve damage: in 8 cases single side lower limb anesthesia with slightly confined walking capacity was reported after HIFU treatment, which recovered within one week. Conclusion: HIFU would be a safe and effective alternative for the treatment of uterine fibroids.

    Purpose. Stenoses and thromboses of vessels feeding the vertebrobasilar territory can evoke serious disturbances including ischemic stroke. We present our experience of endovascular interventions for patients with signs of vertebrobasilar insufficiency (VBI) resulted from subclavian, vertebral and brachiocephalic arterial stenoses. Methods. Twenty-one patients (10 men) aged from 35 to 84 years (mean 64.3 years) with symptoms compatible with VBI underwent balloon angioplasty and stenting of subclavian (SA), innominate (IA) and vertebral (VA) arteries. Procedures were done by radiologists experienced in systematic stenting of the lesions. VBI was manifested by persistent signs in 15 patients, and by transitory ischemic attacks in the posterior circulatory territory in 4 (19%). Two patients (10%) experienced ischemic strokes (in the vertebrobasilar circulation in both cases). In 3 patients (14%) VBI was accompanied by upper limb vascular insufficiency symptoms. All cases were resistant to medical treatment. A neurologist assessed complaints, initial VBI signs and their alteration after intervention in all patients. Outcomes were measured with the 5-point scale suggested by Malek et al.: (1) excellent result (asymptomatic, no neurologic deficits and no symptoms of vertebrobasilar ischemia); (2) good (no neurologic deficits, at most one transient episode of vertebrobasilar ischemia over a period of 3 months after treatment); (3) fair (minimal neurologic deficit and at most one transient episode per month of vertebrobasilar ischemia); (4) poor (no improvement compared with neurologic status before treatment and/or persistent symptoms of vertebrobasilar ischemia); (5) death (regardless of cause). Endovascular treatment was performed for SA stenosis in 15 patients, for SA occlusion in 2, for IA stenosis in 2, and for VA stenosis in 2. There were 15 cases of atherosclerosis, 2 of aortoarteritis, 4 of proximal SA kinking. SA and IA stenoses ranged from 60% to 100% (mean 74

  4. On the Period-Amplitude and Amplitude-Period Relationships

    2008-01-01

    Examined are Period-Amplitude and Amplitude-Period relationships based on the cyclic behavior of the 12-month moving averages of monthly mean sunspot numbers for cycles 0.23, both in terms of Fisher's exact tests for 2x2 contingency tables and linear regression analyses. Concerning the Period-Amplitude relationship (same cycle), because cycle 23's maximum amplitude is known to be 120.8, the inferred regressions (90-percent prediction intervals) suggest that its period will be 131 +/- 24 months (using all cycles) or 131 +/- 18 months (ignoring cycles 2 and 4, which have the extremes of period, 108 and 164 months, respectively). Because cycle 23 has already persisted for 142 months (May 1996 through February 2008), based on the latter prediction, it should end before September 2008. Concerning the Amplitude-Period relationship (following cycle maximum amplitude versus preceding cycle period), because cycle 23's period is known to be at least 142 months, the inferred regressions (90-percent prediction intervals) suggest that cycle 24's maximum amplitude will be about less than or equal to 96.1 +/- 55.0 (using all cycle pairs) or less than or equal to 91.0 +/- 36.7 (ignoring statistical outlier cycle pairs). Hence, cycle 24's maximum amplitude is expected to be less than 151, perhaps even less than 128, unless cycle pair 23/24 proves to be a statistical outlier.

    The objective of the study was to investigate the interactive effect of heat treatment (raw or pasteurized milk), ripening in salted whey (SW) and storage period for up to 3 months on the physicochemical properties of Sudanese braided cheese (SBC). Braided cheeses were manufactured from raw (BCRM) and pasteurized (BCPM) milk and ripened in SW (0%, 5%, and 10% salt) for up to 90 days. All the treatments significantly (P ≤ 0.05) affected the physicochemical characteristics of SBC. The total solid, protein, and fat contents of BCRM or BCPM decreased (P ≤ 0.05), whereas their TA, SN, and salt contents increased significantly (P ≤ 0.05) as storage period and the salt level of the whey were elevated. Both FRI and SRI of BCRM and BCPM increased with the increase in storage period and the salt level of the whey. For SN, FRI, SRI, pH, and moisture contents the magnitude of the change was more pronounced in BCRM than in BCPM, while for protein, fat, salt, and TS contents, the opposite was true; that is, the magnitude of the change was more pronounced in BCPM than in BCRM. Further studies are required to standardize muddaffara cheese manufacturing procedure particularly in rural areas. PMID:26904645

    ST Puppis is a reasonably bright W Virginis variable star, a Type 2 Cepheid with a record of substantial and erratic period changes—21 during the interval 1900 to 1985 with a range of magnitude from 17.4 to 19.2. It was observed as part of Variable Stars South's Cepheid project by Butterworth in 2014 and 2015 using DSLR photometry in BGR passbands and visually by Pearce in 2015. The known period changes are shown graphically and doubtful ones examined and discarded if necessary. With its period and amplitude with a frequently changing period it is a suitable and worthwhile object for visual observing.

    Purpose: To evaluate the safety and efficacy of CT-guided radiofrequency (RF) ablation for the palliative treatment of recurrent unresectable rectal tumors. Materials and Methods: Twenty-seven patients with locally recurrent rectal cancer were treated with computed tomography (CT)-guided RF ablation. Therapy was performed with the patient under conscious sedation with a seven- or a nine-array expandable RF electrode for 8-10 min at 80-110 Degree-Sign C and a power of 90-110 W. All patients went home under instructions the next day of the procedure. Brief Pain Inventory score was calculated before and after (1 day, 1 week, 1 month, 3 months, and 6 months) treatment. Results: Complete tumor necrosis rate was 77.8% (21 of a total 27 procedures) despite lesion location. BPI score was dramatically decreased after the procedure. The mean preprocedure BPI score was 6.59, which decreased to 3.15, 1.15, and 0.11 at postprocedure day 1, week 1, and month 1, respectively, after the procedure. This decrease was significant (p < 0.01 for the first day and p < 0.001 for the rest of the follow-up intervals (paired Student t test; n - 1 = 26) for all periods during follow-up. Six patients had partial tumor necrosis, and we were attempted to them with a second procedure. Although the necrosis area showed a radiographic increase, no complete necrosis was achieved (secondary success rate 65.6%). No immediate or delayed complications were observed. Conclusion: CT-guided RF ablation is a minimally invasive, safe, and highly effective technique for treatment of malignant rectal recurrence. The method is well tolerated by patients, and pain relief is quickly achieved.

    The objective of the present experiment was to study the soft and hard tissue healing following treatment of experimentally induced periimplantitis. 5 labrador dogs about 1-year old were used. The mandibular right and left 1st molars, 4th and 3rd premolars were removed, titanium fixtures (Brånemark System) were installed, and standard abutments were connected in a 2nd stage procedure. After 3 months experimental periimplantitis was induced by the placement of cotton floss ligatures in a submarginal position. 6 weeks later the ligatures were removed. 1 month after ligature removal, an antibiotic regimen was initiated. During a 3-week period, each dog was given tablets of amoxicillin and metronidazole. In the left side of the mandible, buccal and lingual mucoperiosteal flaps were elevated and granulation tissue within the bone craters curetted. The abutments were removed. The exposed outer surfaces and the internal part of the fixtures were carefully cleaned with a detergent (delmopinol HC1). An e-PTFE membrane was placed over each fixture and adjusted to cover the bone crater. New cover screws were fitted through the membranes to the cleaned fixtures. The implants were submerged and the flaps sutured. In the right side of the mandible no local treatment was performed. The dogs were sacrificed after 4 months and biopsies prepared for histological examination. The findings indicated that treatment of a periimplantitis lesion, including comprehensive systemic antimicrobial therapy and cleaning of submerged implants resulted in (i) the elimination of the inflammatory process in the periimplant tissues and (ii) the establishment of a dense connective tissue capsule in direct contact with the previously exposed surface of the implant system. It was also observed that (iii) new bone was frequently laid down on the pristine cover screws. PMID:9151604

  10. Assessing Periodicity of Periodic Leg Movements During Sleep

    2010-01-01

    Background: Periodic leg movements (PLM) during sleep consist of involuntary periodic movements of the lower extremities. The debated functional relevance of PLM during sleep is based on correlation of clinical parameters with the PLM index (PLMI). However, periodicity in movements may not be reflected best by the PLMI. Here, an approach novel to the field of sleep research is used to reveal intrinsic periodicity in inter movement intervals (IMI) in patients with PLM. Methods: Three patient groups of 10 patients showing PLM with OSA (group 1), PLM without OSA or RLS (group 2) and PLM with RLS (group 3) are considered. Applying the “unfolding” procedure, a method developed in statistical physics, enhances or even reveals intrinsic periodicity of PLM. The degree of periodicity of PLM is assessed by fitting one-parameter distributions to the unfolded IMI distributions. Finally, it is investigated whether the shape of the IMI distributions allows to separate patients into different groups. Results: Despite applying the unfolding procedure, periodicity is neither homogeneous within nor considerably different between the three clinically defined groups. Data-driven clustering reveals more homogeneous and better separated clusters. However, they consist of patients with heterogeneous demographic data and comorbidities, including RLS and OSA. Conclusions: The unfolding procedure may be necessary to enhance or reveal periodicity. Thus this method is proposed as a pre-processing step before analyzing PLM statistically. Data-driven clustering yields much more reasonable results when applied to the unfolded IMI distributions than to the original data. Despite this effort no correlation between the degree of periodicity and demographic data or comorbidities is found. However, there are indications that the nature of the periodicity might be determined by long-range interactions between LM of patients with PLM and OSA. PMID:20948585

  11. Robust increase in concurrent hot and dry periods at the global scale

    Ongoing climate change is largely affecting the frequency and magnitude of climate extremes in many areas of the world. Most studies investigating extreme events focus on a single variable such as, for instance, extreme temperature, drought, and heavy precipitation. Often, however, it is compound extremes that have the strongest impacts on ecosystems and society. For example, extreme rainfall in combination with high soil moisture causes floods with severe impacts. Similarly, droughts combined with extreme hot temperatures have particularly devastating impacts on ecosystem functioning. The magnitude of an extreme event can be reflected in its return period. Recently, the concept of copulas has been adapted to estimate multivariate return periods of, e.g., drought extent and duration, peak flow and peak volume, or extreme precipitation events at nearby stations. We use this concept here and estimate bivariate return periods of concurrent hot and dry, and concurrent cold and wet periods of 3 months length on gridded temperature and precipitation data from 1901 onwards. We find a strong increase of concurrent dry and hot periods over the recent decades, in particular in the northern hemisphere. At the same time we detect a decrease in concurrent wet and cold periods. This can be primarily attributed to the strong increase in temperature in many land areas. Averaged over the land surface, the variations of concurrently dry and hot, and cold and wet periods over the 20th century can be related to changes in surface radiation (global dimming and global brightening), which affected both temperature and the hydrological cycle.

    Hypertonia and hyperactivity of masticatory muscles are involved in pain and contractions of the cervical spine musculature, but their pathophysiology remains nonetheless unknown and its treatment far to be codified. In this study, 8 patients, showing disabling posterior neck muscle contractures linked with bruxism were prospectively treated and followed for an average 15 months period, after having received Injections of botulinum toxin A essentially in masticatory muscles. Injections were made every 3 months, varying from 10 to 100 U Botox* by muscles, without administrating more than 300 U Botox* in the same patient. The angle of cervical lordosis were calculated on lateral sitting radiographs in neutral position, good results being considered to be achieved in the case of a 2 point diminution of VAS score as well as at least a 5° positive gain in the curve. 7 patients out of 8 showed a real improvement in their symptoms after an average of 3 injections, showing a decrease of 4.5 points on the VAS score and an average increment of 15° in cervical lordosis. Although the follow-up period of patients was relatively short and the sample quite small, the general impression, confirmed by the patients' experience, seems to suggest a potential place for the use of botulinum toxin amongst the array of treatments which can be offered in certain selected cases which associate bruxism and posterior cervical contractions.

    The treatment of obesity is an often studied subject. Although reductions in weight and improvements in cardiometabolic risk factors are important aims of obesity treatment, improvements in quality of life and eating behaviour are also relevant outcomes. In this practice-based study, we evaluated an 18-month commercial multidisciplinary obesity treatment programme and report on treatment results for weight, cardiometabolic risk factors, eating behaviour and quality of life. From a local commercial obesity treatment centre, 426 subjects (65% female; 45.4 ± 12.2 years; body mass index 40.0 ± 6.6 kg m(-2)) were recruited. Measurements of body weight, height, body composition, waist circumference and blood pressure were scheduled at baseline and every 3 months, whereas fasting blood collections were scheduled at baseline and every 6 months. At the same time points, participants were asked to fill in questionnaires on dietary intake, eating behaviour and quality of life. After 18 months of treatment programme, average weight change [mean (95% confidence interval)] was -10.9 kg (-14.8 to -7.0; P < 0.001) for the completers (n = 181) and -10.8 kg (-14.2 to -7.4; P < 0.001) for the intention-to-treat population (n = 426). Waist circumference (mean ± standard error of the mean) (-0.13 ± 0.01 cm; P < 0.001), fat mass (-7.8 ± 1.3 kg; P < 0.001) systolic (-11.4 ± 2.0; P < 0.001) and diastolic (-7.0 ± 1.3; P < 0.001) blood pressure, triglycerides (-0.4 ± 0.1; P = 0.004) and plasma glucose (-0.6 ± 0.2; P = 0.001) were significantly reduced. The PCS scale of the SF-36 and all three scales of the three-factor eating questionnaire improved significantly over the 18-month treatment period. All collected data in this study provide evidence that a multidisciplinary treatment programme based on lifestyle modification results in significant weight loss and improvements in cardiometabolic

    We present results of the fast Fourier transform (FFT), the MEM analysis, and the wavelet analysis (WA), of the temporal variation of the monthly disk integrated "CaII-K plage-area and enhanced network (EN) area" hereafter called `plage index' derived by Tlatov et al. (2009), from spectro-heliograms taken in Ca II K line at Kodaikanal Observatory, from February 1907 to April, 1998, In the range {>}3 months and < decade, the Fourier transform power spectra reveal solar cycle periodicity {˜}122 months, its sub-harmonic ˜61 months, two short quasi-periodicities ({>}2 and <4 months), and nine `intermediate-range' quasi-periodicities (≳ 4 mo and <11 yr), in the variation of the plage index. The quasi-periodicities include Rieger, Rieger type and quasi-biennial. The presence of quasi-periodicities and the mean values of the periods are confirmed by the maximum entropy method (MEM). The temporal spans of the quasi-periodicities during different solar cycles are determined from the complex Morlet-wavelet analyses. The Rieger quasi-periodicity (150-160 days) appeared during cycle 21 and cycle 22. Each of the quasi-periodicities in the studied range lies close to one or more planetary periodicities (orbital, or spring tidal, or heliocentric conjunction frequency). We discuss possible interpretations of our results, and those of similar results obtained earlier by other authors, towards understanding the mechanisms of excitation of various quasi-periodicities detected in solar variability parameters.

  2. Forward Period Analysis Method of the Periodic Hamiltonian System

    Wang, Pengfei

    2016-01-01

    Using the forward period analysis (FPA), we obtain the period of a Morse oscillator and mathematical pendulum system, with the accuracy of 100 significant digits. From these results, the long-term [0, 1060] (time unit) solutions, ranging from the Planck time to the age of the universe, are computed reliably and quickly with a parallel multiple-precision Taylor series (PMT) scheme. The application of FPA to periodic systems can greatly reduce the computation time of long-term reliable simulations. This scheme provides an efficient way to generate reference solutions, against which long-term simulations using other schemes can be tested. PMID:27727295

  3. Periodic and aperiodic synchronization in skilled action.

    PubMed

    Cummins, Fred

    2011-01-01

    Synchronized action is considered as a manifestation of shared skill. Most synchronized behaviors in humans and other animals are based on periodic repetition. Aperiodic synchronization of complex action is found in the experimental task of synchronous speaking, in which naive subjects read a common text in lock step. The demonstration of synchronized behavior without a periodic basis is presented as a challenge for theoretical understanding. A unified treatment of periodic and aperiodic synchronization is suggested by replacing the sequential processing model of cognitivist approaches with the more local notion of a task-specific sensorimotor coordination. On this view, skilled action is the imposition of constraints on the co-variation of movement and sensory flux such that the boundary conditions that define the skill are met. This non-cognitivist approach originates in the work of John Dewey. It allows a unification of the treatment of sensorimotor synchronization in simple rhythmic behavior and in complex skilled behavior and it suggests that skill sharing is a uniquely human trait of considerable import.

    2016-03-01

    Concussions commonly occur in adolescents. Although the majority of adolescent patients' symptoms resolve, about 11% continue to experience symptoms at 3 months. Standard treatment options for prolonged symptoms are not available, and the role of osteopathic manipulative treatment in the management of adolescent concussions is unclear. The authors describe a case of a 16-year-old girl with a history of 3 head injuries who presented with concussion symptoms. After 6 weekly osteopathic manipulative treatment sessions, the patient was able to return to her normal activities. Further research on the role of osteopathic manipulative treatment to manage concussions is needed.

    2004-01-01

    This paper generalizes and extends the concept of the Schuler oscillation that occurs in the theory of inertial navigation systems, allowing one to see how the Schuler phenomenon affects inertial navigation systems operating in space. We show why a low earth orbit satellite's orbital period is identical to the period of the Schuler pendulum, which is the period of the errors for terrestrial inertial navigation systems. We also show that the generalized form of the Schuler oscillation takes the same form as the Hill-Clohessy-Wiltshire equations for satellite relative motion and that the period of the out-of-plane motion in neighboring satellite relative trajectories is the same as the Schuler period. Finally, we describe how INS gyro drift manifests itself in different coordinate systems for the orbital case. These results may assist orbital flight dynamics and attitude control systems engineers in the design and analysis of INS-equipped spacecraft

    2016-08-01

    The spectra of the PROBA2/LYRA data, similarly to every other solar time series, show predominant periodicities that can be of solar or instrumental origin. In this article, we compare the main periodicities characterizing the LYRA spectrum to those found in the sunspot number, in the 10.7 cm flux, in an X-ray flare index, and in the sunspot area evolution. We focused on the 2010 to 2014 time range, for which the LYRA data are available, although we also briefly address the evolution of the main periodicities in the longer range. The mid-term periodicities at {˜} 28, {˜} 44, {˜} 54, {˜} 59, {˜} 100, {˜} 110, and {˜} 150 days appear as highly significant in several analyzed datasets. The consistency of distinct periodicities between datasets provides characteristics for the global Sun. This consistency also strengthens the reliability of LYRA data.

    Treatments for acute distal radioulnar joint (DRUJ) instability with distal radius fracture vary from conservative to operative treatment, although it seems to be no consensus regarding which treatment is optimal. This prospective randomized study was designed to compare the clinical outcomes for operative and conservative treatment of acute DRUJ instability with distal radius fracture, according to the presence or absence and type of ulnar styloid process fracture and the degree of its displacement. Between July 2008 and February 2013, we enrolled 157 patients who exhibited an unstable DRUJ during intraoperative manual stress testing (via the ballottement test) after fixation of the distal radius. Patients were classified according to the type of the ulnar styloid process fracture, using preoperative wrist radiography, and each group was divided into subgroups, according to their treatment method. We then compared the clinical outcomes between the conservative and operative treatments, using their range of motion; Disabilities of the Arm, Shoulder, and Hand score; modified Mayo wrist score; and grip strength. At 3 months after surgery, among patients without ulnar styloid process fracture, the flexion-extension range was 79 ± 15° after supination sugar-tong splinting (group A-1), 91 ± 14° after DRUJ transfixation (group A-2), and 89 ± 10° after arthroscopic triangular fibrocartilage complex repair (group A-3); the operative treatments provided greater joint motion ranges than conservative treatment. The groups with ulnar styloid process fractures at the tip (group B) or base (group C) also exhibited better clinical outcomes after the operative treatments, compared with after the conservative treatment. However, at the final follow-up, groups A-1, A-2, and A-3 exhibited similar flexion-extension ranges (122 ± 25°, 119° ± 18°, and 120° ± 16°, respectively) and modified Mayo wrist scores (87 ± 7, 89 ± 8, and 85 ± 9). Thus, the conservative and

    The Chandra surveys have resulted in a wealth of data on low-luminosity X-ray sources (Lx 1030-34 erg/s) of Galactic scales beyond the local solar neighborhood. Many of these are compact binaries, in particular, cataclysmic variables, often identified by their periodic X-ray variability and spectra. Hong et al. (2009, 2011) have used energy quantiles (Hong, Schlegel & Grindlay, 2004) as a fast, robust indicator of spectral hardness and absorption of the X-ray sources. Energy quantiles also enable a simple but effective illustration of spectral changes with phase in these periodic systems: e.g. absorption by the accreting material is understood to drive the periodic light-curves. An interesting question is how to best make use of the information encapsulated in the periodic change in energy spectrum, along with the periodic change in intensity, especially for cases of ambiguous period determination? And, how to do it computationally efficiently? A first approach is to do the period search in intensity, as is standard; and then use a criterion of spectral variation to verify possible periods. Huijse, Zegers & Protopapas (2011) recently demonstrated a powerful period estimation technique using information potential and correntropy embedded in the light curve. Similar quantities based on energies (or energy quantiles) of X-ray photons can serve as criteria of spectral variation. A different approach treats the spectrum variations and intensity variations completely independently, searching through period-space in each, and then combining the results. A more general method would include both at the same time, looking for statistically significant variations above what is expected for a constant (in intensity and spectrum).

  9. Periodic and Quasi-Periodic Orbitsfor the Standard Map

    Berretti, Alberto; Gentile, Guido

    We consider both periodic and quasi-periodic solutions for the standard map, and we study the corresponding conjugating functions, i.e. the functions conjugating the motions to trivial rotations. We compare the invariant curves with rotation numbers ω satisfying the Bryuno condition and the sequences of periodic orbits with rotation numbers given by their convergents ωN = pN/qN. We prove the following results for N--> ∞: (1) for rotation numbers ωNN we study the radius of convergence of the conjugating functions and we find lower bounds on them, which tend to a limit which is a lower bound on the corresponding quantity for ω (2) the periodic orbits consist of points which are more and more close to the invariant curve with rotation number ω (3) such orbits lie on analytical curves which tend uniformly to the invariant curve.

    2016-09-01

    Recurrent fever is a common presentation in paediatric practice and can be caused by a wide variety of diseases including autoinflammatory conditions. The innate immune system plays an essential role in the 'first line' response to infection through mediation of inflammatory responses. Inflammasomes are part of the regulatory process for this system and result in the production of the powerful pro-inflammatory cytokine interleukin-1B. Dysregulation of inflammasomes, and Interleukin 1 production, contributes to the pathogenesis of autoinflammatory diseases. This review focuses on described periodic fever syndromes (PFS) which are now collectively referred to as autoinflammatory syndromes. Conditions discussed include periodic fever aphthous stomatitis pharyngitis and cervical adenopathy, familial Mediterranean fever, tumour necrosis factor receptor-associated periodic syndromes, hyperimmunoglobulinaemia D and the cryopyrin-associated periodic syndromes. Presenting features, complications, diagnostic and treatment approaches for these conditions are discussed. Nonetheless, as most of these conditions are rare and may have significant long-term complications, it is recommended that they be managed in consultations with a physician experienced in managing PFS.

    The observed-minus-calculated (O-C) diagrams of the eclipse timings of three dwarf novae of the SU UMa sub-class are presented and discussed. The (O-C) diagrams cover 28 24 and 15 years respectively for Z~Cha V2051~Oph and V4140~Sgr and show clear orbital period changes. Z~Cha shows conspicuous cyclical changes of period 28+/-2 yr and amplitude 60+/-12 s. V2051~Oph shows a cyclical period change of period 22+/-2 yr and amplitude 17+/-3 s. The (O-C) diagram of V4140~Sgr shows less convincing evidence but can also be explained in terms of a cyclical period modulation with an amplitude of about 16s and a time scale of 6.9+/-0.3 years. The best explanation for these observations is that of a solar-type magnetic activity cycle in the secondary star modulating its radius and consequently the mass transfer rate and the orbital separation on time scales of years. These results support the recent findings of Ak Ozkan & Mattei that the quiescent magnitudes and outburst interval of a sample of dwarf novae (including many SU UMa stars) show cyclical variations produced by solar-type magnetic activity cycles. Our results also confirm that the fully-convective secondary stars of these short period binaries still possess non-negligible magnetic fields.

    Alzheimer disease (AD) primarily affects older adults. This neurodegenerative disorder is the most common cause of dementia and is a leading source of their morbidity and mortality. Patient care costs in the United States are about 200 billion dollars and will more than double by 2040. This case report describes the remarkable improvement in a patient with advanced AD in hospice who received 5 computed tomography scans of the brain, about 40 mGy each, over a period of 3 months. The mechanism appears to be radiation-induced upregulation of the patient’s adaptive protection systems against AD, which partially restored cognition, memory, speech, movement, and appetite.

  13. Spirulina platensis versus silymarin in the treatment of chronic hepatitis C virus infection. A pilot randomized, comparative clinical trial

    PubMed Central

    2012-01-01

    Background Spirulina platensis, a cynobacterium used frequently as a dietary supplement had been found to exhibit many immune-stimulating and antiviral activities. It had been found to activate macrophages, NK cells, T cells, B cells, and to stimulate the production of Interferon gamma (IFN-γ) and other cytokines. Natural substances isolated from Spirulina platensis had been found to be potent inhibitors against several enveloped viruses by blocking viral absorption/penetration and some replication stages of progeny viruses after penetration into cells. We aimed to study whether this dietary supplement possesses any therapeutically feasible activity worthy of further larger controlled clinical evaluation. Methods Sixty six patients with chronic hepatitis C virus infection and eligible for inclusion had been randomized to either Spirulina or Silymarin treated groups for a period of six months treatment. The two groups were followed up and blindly compared for early (after 3 months) and end of 6 months treatment virological response. The effects of both treatments on each of alanine aminotransferase (ALT), Chronic Liver Disease Questionnaire scores (CLDQ), Arizona Sexual Experience Scale scores (ASEX) and the occurrence of any attributable adverse events were also compared. Results Among the 30 patients who had been treated with Spirulina and completed the 6 months protocol, 4 patients (13.3%) had a complete end of treatment virological response and 2 patients (6.7%) had a partial end of treatment response defined as significant decrease of virus load of at least 2-logs10. Though the proportion of responders in Spirulina group was greater than in the Silymarin group, the difference was not statistically significant at the end of both 6 months (p = 0.12) and 3 months treatment (p = 0.22) by Exact test. Alanine aminotransferase as well as CLDQ and ASEX scores were found to be more significantly improved in Spirulina than in Silymarin treated group. Conclusions Our

    The purpose of this article is to describe feasibility, safety, and outcome results from a treatment development trial of the SAFETY Program, a brief intervention designed for integration with emergency services for suicide-attempting youths. Suicide-attempting youths, ages 11 to 18, were enrolled in a 12-week trial of the SAFETY Program, a cognitive-behavioral family intervention designed to increase safety and reduce suicide attempt (SA) risk (N = 35). Rooted in a social-ecological cognitive-behavioral model, treatment sessions included individual youth and parent session-components, with different therapists assigned to youths and parents, and family session-components to practice skills identified as critical in the pathway for preventing repeat SAs in individual youths. Outcomes were evaluated at baseline, 3-month, and 6-month follow-ups. At the 3-month posttreatment assessment, there were statistically significant improvements on measures of suicidal behavior, hopelessness, youth and parent depression, and youth social adjustment. There was one reported SA by 3 months and another by 6 months, yielding cumulative attempt rates of 3% and 6% at 3 and 6 months, respectively. Treatment satisfaction was high. Suicide-attempting youths are at high risk for repeat attempts and continuing mental health problems. Results support the value of a randomized controlled trial to further evaluate the SAFETY intervention. Extension of treatment effects to parent depression and youth social adjustment are consistent with our strong family focus and social-ecological model of behavior change.

    The article deals with a case report concerning successful stagewise treatment of a patient presenting with a giant false abdominal aortic paraanastomotic aneurysm having developed 2 months after an operation of linear prosthetic repair for a juxtarenal aneurysm with reimplantation of the left renal artery. The secondary operation was carried out 3 months after aortic reconstruction. The first stage consisted in performing endovascular prosthetic repair of the abdominal aortic paraanastomotic pseudoaneurysm by means of a bifurcated stent graft Endurant II (Medtronic), with the second stage being laparotomy with the removal of the retroperitoneal haematoma. The postoperative period turned out uneventful. The patient was discharged from hospital on the 8th day after the second operation. The patient was examined 2 months later, presenting no complaints and returning to his previous work. According to the findings of the check-up duplex scanning, the graft was patient, with no evidence of a paraanastomotic aneurysm. This is followed by discussion of the problems regarding the use of surgical and endovascular technologies in treatment of paraanastomotic aortic aneurysms. PMID:27336337

    Patients with cancer are at increased risk of venous thromboembolism (vte). Anticoagulation therapy is used to treat vte; however, patients with cancer have unique clinical circumstances that can often make decisions surrounding the administration of therapeutic anticoagulation complicated. No national Canadian guidelines on the management of established cancer-associated thrombosis have been published. We therefore aimed to develop a consensus-based, evidence-informed guideline on the topic. PubMed was searched for clinical trials and meta-analyses published between 2002 and 2013. Reference lists of key articles were hand-searched for additional publications. Content experts from across Canada were assembled to review the evidence and make recommendations. Low molecular weight heparin is the treatment of choice for cancer patients with established vte. Direct oral anticoagulants are not recommended for the treatment of vte at this time. Specific clinical scenarios, including the presence of an indwelling venous catheter, renal insufficiency, and thrombocytopenia, warrant modifications in the therapeutic administration of anticoagulation therapy. Patients with recurrent vte should receive extended (>3 months) anticoagulant therapy. Incidental vte should generally be treated in the same manner as symptomatic vte. There is no evidence to support the monitoring of anti–factor Xa levels in clinically stable cancer patients receiving prophylactic anticoagulation; however, levels of anti–factor Xa could be checked at baseline and periodically thereafter in patients with renal insufficiency. Follow-up and education about the signs and symptoms of vte are important components of ongoing patient care. PMID:25908913

    2013-09-01

    Abstract Our zebrafish colony experienced a period of increased mortality rate of 6.5 times more deaths per month in a colony of over 13,000 zebrafish (Danio rerio), which developed over 3 months. We observed that before death, affected fish appeared emaciated, often with an abdominal bulge. We performed dissection on 18 fish that had this appearance and found in 15 that their gut was infected with a nematode that closely resembled Pseudocapillaria tomentosa. We devised a treatment protocol for this nematode infection, which involved addition of fenbendazole, a drug used to treat nematode infections in cattle and sheep, to the fish feed. Fenbendazole produced no severe side effects in the fish and several treatments have effectively eradicated the parasite from our colony. The mortality rate of our fish has decreased to a value of 0.7%/month (p<0.001, equal to that before the infection). We propose this protocol as an inexpensive alternative to having to rederive an entire colony from bleached eggs, and as a prophylactic measure used in quarantine facilities on a regular basis.

    Background: Secondary hyperparathyroidism (sHPT) is a common acquired disorder in patients with chronic renal failure. Despite the development of new therapeutic agents, a majority of patients will require parathyroidectomy. The aim of this study was to evaluate total parathyroidectomy with auto-transplantation of trace amounts of parathyroid tissue as a surgical option in uremia sHPT treatment. Methods: Clinical data of 50 sHPT patients who underwent total parathyroidectomy with auto-transplantation between January 2011 and December 2013 were reviewed retrospectively. Symptoms such as bone pain and fractures, concentrations of intact parathyroid hormone (iPTH), levels of ionized calcium and serum phosphorus, and activity of alkaline phosphatase were recorded before and after parathyroidectomy. Results: After operation, signs of pruritus, bone pain and muscle weakness was disappeared, iPTH level and serum phosphate concentration were declined markedly. No serious postoperative complications were observed. Follow-up observation was around 28 months. One female patient (2%) died 3 months after surgery due to heart failure, and another patient (2%) had persistent disease. All other patients recovered during the follow-up period. Conclusions: Total parathyroidectomy with auto-transplantation of trace amounts of parathyroid tissue was considered to be a feasible, safe and effective surgical option for the treatment of sHPT.

    To evaluate the results of stent placement for obstructive atherosclerotic aortic disease with or without involvement of the common iliac artery. Forty patients had self-expanding stents primarily or after balloon dilatation in the abdominal aorta between January 2005 and May 2011. All patients had trouble walking. Follow-up examinations were performed with clinical visits; these included color Doppler ultrasonography and computed tomographic angiography. Technical, clinical, and hemodynamic success was achieved in all patients. None of the patients underwent reintervention during the follow-up period, which ranged from 3 months to 6 years (median 24 months). Nine complications occurred in six patients. Of the nine complications, four were distal thromboembolisms, which were successfully treated with catheter-directed thrombolysis or anticoagulation therapy. Endovascular treatment of the obstructive aortic disease using self-expanding stents was safe and effective, with high technical success and long-term patency. Thromboembolic complications were high even though direct stenting was considered protective for thromboembolism formation. Particularly for infrarenal aortic stenosis, it can be recommended as the first-line treatment option for patients with obstructive atherosclerotic aortic disease.

    Background Pharmacotherapy studies involving buprenorphine have rarely been conducted with US community corrections populations. This is one of the first reports of buprenorphine treatment outcomes of adult opioid-dependent probationers and parolees. Methods This longitudinal study examined the 3-month treatment outcomes for a sample of probation and parole clients (N=64) who received community-based buprenorphine treatment. Results Approximately two-thirds of the sample (67%) were still in treatment at three months post-baseline. Furthermore, there was a significant decline in the number of self-reported heroin use days and crime days from baseline to three months post-baseline. While there was not a significant reduction in reincarcerations, there was no evidence that they had increased. Conclusions Given that buprenorphine is approved by the FDA as a safe, effective treatment for opioid use disorders, individuals on parole or probation should have the opportunity to benefit from it through community-based programs.

    Objective The aim of this study is to assess the effectiveness of oral progestin treatment in women diagnosed with complex atypical hyperplasia (CAH) or grade 1 endometrial cancer (G1EC), who desire to preserve their fertility, as alternative treatment to a hysterectomy. Methods We reviewed the medical records of women younger than 45 years old that had been diagnosed with CAH or G1EC, who expressed a desire to preserve their fertility using alternative treatment at our institution. Women without evidence of myometrial invasion on pelvic magnetic resonance imaging scans were included. The study period was between 2004 and 2014. Endometrial biopsies were taken at follow-up appointments. Results We identified 31 young women with CAH or G1EC. The median age was 33 years old (range, 20 to 41), and the median period of time undertaking the treatment was 5 months (range, 1 to 12). Twenty-three patients (74.2%) achieved complete remission (CR; median time to CR was 3 months; range, 1 to 22), 16 patients (88.9%) with CAH and 7 (53.8%) with G1EC achieved CR. 6 patients (26.1%) who had achieved CR, had recurrence of the disease (median time from CR to recurrence was 12.5 months; range, 4 to 18). Eight patients (25.8%) finally underwent a hysterectomy. Conclusion Oral progestin therapy is an alternative treatment for women with CAH or G1EC who desire fertility preservation. However, more prospective studies are needed for standard progestin regimen. Also, there still remains a risk of disease progression and recurrence. Therefore, close follow-up is important during treatment and after CR. In addition, a hysterectomy is recommended as a definitive treatment after completion of childbearing. PMID:26866032

    Twenty-one patients (age range, 15 to 26; 18 patients 15 to 20 years old) had proximal diaphyseal fractures of the fifth metatarsal. Clinical records and radiographs for all patients were available for review. Patient treatment had been individualized and included several methods, including rest, plaster immobilization, and bone grafting. Twenty of the 21 patients were boys or men participating in athletics. Nine of the 21 fractures and 8 of the reinjuries were sustained while playing basketball. Healing required a minimum of 3 months (with bone graft) and some fractures were not radiographically healed at 20 months, although the patients were clinically asymptomatic. The fracture of the proximal shaft of the fifth metatarsal, particularly the 1.5-cm segment distal to the tuberosity, is a troublesome injury in the active athlete. The clinical course does not appear to be influenced by the usual initial conservative treatment modalities, although many of these fractures will heal if the athlete is willing to restrict activities for a prolonged period of time. In this series, bone grafting with a tibial corticocancellous graft after thorough curettage of sclerotic bone obliterating the medullary canal was the most effective treatment modality for delayed union.

    We report the case of a 42-year-old Zairian male who presented with paroxysmal attacks of hypertension accompanied by spontaneous recurrent hypothermia and profuse sweating of unknown origin. Routine and extensive examination failed to indicate a usual cause of arterial hypertension or for periodic hypothermia. Based on the hypothesis of an epileptic center influencing both the thermoregulatory and the vasomotor mechanisms, an anticonvulsant treatment was successfully installed. The present study makes a correlation between the present condition and certain neurologic abnormalities described in the literature. PMID:1337813

    Perinatal substance use remains a major public health problem and is associated with a number of deleterious maternal and fetal effects. Polysubstance use in pregnancy is common, and can potentiate adverse maternal and fetal outcomes. Tobacco is the most commonly used substance in pregnancy, followed by alcohol and illicit substances. The treatments for perinatal substance use are limited and consist mostly of behavioral and psychosocial interventions. Of these contingency management has shown the most efficacy. More recently, novel interventions such as progesterone for postpartum cocaine use have shown promise. The purpose of this review is to examine the recent literature on the use of tobacco, alcohol, cannabis, stimulants, and opioids in the perinatal period, their effects on maternal and fetal health and current treatments.

    The calcium channel antagonist nifedipine has shown efficacy in the treatment of interstitial cystitis and the urethral syndrome. The optimal daily dose of nifedipine can be determined with the use of a nifedipine titration test. To complete the repair of damaged bladder and/or urethral mucosa, nifedipine therapy should be used for a minimum of 3 months. Patients who do not respond well to nifedipine are those with the pelvic floor muscle spasm syndrome variant of interstitial cystitis.

    Catheter-based renal denervation is a new method able to disrupt renal sympathetic nerves located in the adventitia of renal arteries. A randomized clinical trial showed a decrease in blood pressure in resistant hypertensive patients. In order to guide clinicians and interventional practitioner for the use of this new approach, different French scientific societies (Hypertension, Cardiology and Radiology) decided to combine their expertise and propose an expert consensus to assess benefit/risk ratio of this technique in the field of arterial hypertension. In 2012, this expert consensus propose to limit renal denervation technique to patients with essential hypertension uncontrolled by four or more antihypertensive therapies with at least one treatment being a diuretic and spironolactone at a dose of 25mg shown to be unable to control blood pressure. Measurement of office BP should be at least with SBP more than 160mmHg and/or DBP more than 100mmHg confirmed by ambulatory BP measurement (home or ABP measurement with SBP more than 135mmHg and DBP more than 85mm during daytime period). Finally, renal artery anatomy and function should allow proper intervention (i.e., two functional kidneys, absence of previous renal angioplasty). Renal enervation is a complex interventional procedure with potentially arterial complications, training is required for practitioners. Antihypertensive treatment should not be interrupted immediately after renal denervation since blood pressure lowering effect are delayed and reached maximum effect after 3 months. Monitoring of blood pressure, renal function and anatomy of renal arteries is required 12 months and 36 months after procedure. The expert consensus requires the inclusion of patients experiencing this procedure in a observational study with record form and follow-up.

  11. Sphenopalatine ganglion stimulation for the treatment of cluster headache

    PubMed Central

    Puche, Miguel; Garcia, Ana; Gascón, Francisco

    2014-01-01

    Cluster headache is a severe, debilitating disorder with pain that ranks among the most severe known to humans. Patients with cluster headaches have few therapeutic options and further, 10–20% develop drug-resistant attacks. The often brief duration of cluster attacks makes abortive therapy a challenge, and preventive medications are almost always provided to patients, but the side effects of these preventive medications can be significant. The sphenopalatine ganglion (SPG) is believed to play a role in headache pain and cranial autonomic symptoms associated with cluster headache, which is a result of activation of the trigeminal-autonomic reflex. For over 100 years, the SPG has been a clinical target to treat primary headache disorders using pharmacologic and nonpharmacologic methods. Radiofrequency lesioning and nerve-resection therapies, while initially beneficial, are irreversible procedures, and the use of neurostimulation provides one method of interfacing with the neural pathways without causing permanent damage to neural tissue. SPG neurostimulation is both reversible and adjustable, and has recently been tested in both proof-of-concept work and in a randomized, sham-controlled trial for the treatment of cluster headache. A randomized, sham-controlled study of 32 patients was performed to evaluate further the use of SPG stimulation for the acute treatment of chronic cluster headache. Of the 32 patients, 28 completed the randomized experimental period. Overall, 68% of patients experienced an acute response, a frequency response, or both. In this study the majority of adverse events were related to the implantation procedure, which typically resolved or remained mild in nature at 3 months following the implant procedure. This and other studies highlight the promise of using SPG stimulation to treat the pain-associated cluster headache. SPG stimulation could be a safe and effective option for chronic cluster headache.

    The aim of the study was to evaluate the efficacy and safety of a selective serotonin reuptake inhibitor (SSRI) drug dapoxetine in delaying ejaculation in patients with premature ejaculation (PE). A total of 212 potent men with PE were randomly assigned to receive 30 mg orally dapoxetine (group 1, N=106) twice daily or similar regimen of placebo (group 2, N=106) during a 12-week period for each agent. Pretreatment evaluation included history and physical examination, geometric mean intravaginal ejaculatory latency time (IELT, primary outcome measure), and International Index of Erectile Function (IIEF). The efficacy of two treatments was assessed every 2 weeks during treatment, at the end of study, and in 3-month follow-up after cessation of treatment. We measured geometric mean IELT. Thus, the IELT values were logarithmically transformed before statistical analysis, and the results are reported as fold increases from baseline with associated 95% confidence intervals (CI). The independent sample two-tailed t-test was used to compare the IELTs. At the end of 12-week treatment, the dapoxetine group had a 2.9- (95% CI, 1.84-4.16) fold increase of the geometric mean IELT, while after placebo the geometric mean IELT did not increase significantly (1.4-fold increase; 95% CI, 0.84-1.63) (p=0.001). The mean weekly intercourse episodes increased from pretreatment values of 1.16 and 1.14 to 2.2 and 1.4, for dapoxetine and placebo, respectively (p=0.04). Baseline mean intercourse satisfaction domain values of IIEF, 12 and 11, reached to 16 and 10 at the 12-week treatment in groups 1 and 2, respectively (p=0.04). At the end of 3-month follow-up period, the geometric mean IELT in dapoxetine and placebo group demonstrated 1.4- (95% CI, 0.66-1.46) and 1.3- (95% CI, 0.77-1.63) fold increase, respectively (p=0.1). Three-month intercourse satisfaction domain value of IIEF was 11 in group 1 and 10 in group 2 (p=0.1). Mean number of adverse events was 19 for dapoxetine and 7 for

  13. Effect of periodontal treatment on the clinical parameters of patients with rheumatoid arthritis: study protocol of the randomized, controlled ESPERA trial

    2013-01-01

    Background Rheumatoid arthritis (RA) is a chronic inflammatory disorder that leads to joint damage, deformity, and pain. It affects approximately 1% of adults in developed countries. Periodontitis is a chronic oral infection, caused by inflammatory reactions to gram-negative anaerobic bacteria, and affecting about 35 to 50% of adults. If left untreated, periodontitis can lead to tooth loss. A significant association has been shown to exist between periodontitis and RA in observational studies. Some intervention studies have suggested that periodontal treatment can reduce serum inflammatory biomarkers such as C-reactive protein, or erythrocyte sedimentation rate. We hypothesize that periodontitis could be an aggravating factor in patients with RA, and that its treatment would improve RA outcomes. The aim of this clinical trial is to assess the effect of periodontal treatment on the biological and clinical parameters of patients with RA. Methods/design The ESPERA (Experimental Study of Periodontitis and Rheumatoid Arthritis) study is an open-label, randomized, controlled trial. Subjects with both RA and periodontitis will be recruited at two university hospitals in southwestern France. In total, 40 subjects will be randomized into two arms (intervention and control groups), and will be followed up for 3 months. Intervention will consist of full-mouth supra-gingival and sub-gingival non-surgical scaling and root planing, followed by systemic antibiotic therapy, local antiseptics, and oral hygiene instructions. After the 3-month follow-up period, the same intervention will be applied to the subjects randomized to the control group. The primary outcome will be change of in Disease Activity Score in 28 Joints (DAS28) at the end of the follow-up period. Secondary outcomes will be the percentages of subjects with 20%, 50%, and 70% improvement in disease according to the American College of Rheumatology criteria.

    Stimulated by the recent discovery of the 1 yr recurrence period nova M31N 2008-12a, we examined the shortest recurrence periods of hydrogen shell flashes on mass-accreting white dwarfs (WDs). We discuss the mechanism that yields a finite minimum recurrence period for a given WD mass. Calculating the unstable flashes for various WD masses and mass accretion rates, we identified a shortest recurrence period of about two months for a non-rotating 1.38 M {sub ☉} WD with a mass accretion rate of 3.6 × 10{sup –7} M {sub ☉} yr{sup –1}. A 1 yr recurrence period is realized for very massive (≳ 1.3 M {sub ☉}) WDs with very high accretion rates (≳ 1.5 × 10{sup –7} M {sub ☉} yr{sup –1}). We revised our stability limit of hydrogen shell burning, which will be useful for binary evolution calculations toward Type Ia supernovae.

    The paper presents the detailed design and some preliminary results obtained from a study regarding a wastewater treatment pilot plant (WWTPP), serving as a multistage constructed wetland (CW) located at the rural settlement of 'Chorfech 24' (Tunisia). The WWTPP implemented at Chorfech 24 is mainly designed as a demonstration of sustainable water management solutions (low-cost wastewater treatment), in order to prove the efficiency of these solutions working under real Tunisian conditions and ultimately allow the further spreading of the demonstrated techniques. The pilot activity also aims to help gain experience with the implemented techniques and to improve them when necessary to be recommended for wide application in rural settlements in Tunisia and similar situations worldwide. The selected WWTPP at Chorfech 24 (rural settlement of 50 houses counting 350 inhabitants) consists of one Imhoff tank for pre-treatment, and three stages in series: as first stage a horizontal subsurface flow CW system, as second stage a subsurface vertical flow CW system, and a third horizontal flow CW. The sludge of the Imhoff tank is treated in a sludge composting bed. The performances of the different components as well as the whole treatment system were presented based on 3 months monitoring. The results shown in this paper are related to carbon, nitrogen and phosphorus removal as well as to reduction of micro-organisms. The mean overall removal rates of the Chorfech WWTPP during the monitored period have been, respectively, equal to 97% for total suspended solids and biochemical oxygen demand (BOD5), 95% for chemical oxygen demand, 71% for total nitrogen and 82% for P-PO4. The removal of E. coli by the whole system is 2.5 log units.

    Consumption of minimally processed fruit and vegetables has increased significantly in the past few years due to the consumers' life style. The aim of this study was to evaluate the effect of treatment with ascorbic acid or calcium chloride on the quality parameters of fresh-cut kiwifruit prepared from fruit previously stored for 3 months, either treated or not treated with 1-methylcyclopropene (1-MCP) before storage. Harvested fruit were treated with 1 microL L(-1) 1-MCP for 20 h at room temperature ( approximately 20 degrees C) (MCP) or had no treatment (C) and were then stored at 0 degrees C. After 3 months, fruit were removed from storage, peeled, and cut longitudinally in quarters, dipped in 2% ascorbic acid (Asc), 2% calcium chloride (Ca), or just water (cont), and kept at 2 degrees C for 8 days. Measurements of firmness, soluble solids content (SSC) ( degrees Brix), color (CIE L*, a*, b*), electrolyte leakage, sugars, organic acids, total phenolics, and antioxidant activity (DPPH and ABTS) were performed at 0, 4, and 8 days. A taste panel was performed on the seventh shelf life day. It was shown that whole MCP-treated kiwifruit kept better than the control through the 3 months storage, this effect being lost through the fresh-cut shelf life period. Furthermore, the postcut dip on 2% CaCl(2) was effective on delaying softening and browning of fresh-cut kiwifruit, which were also the fruit preferred by panelists. Both ascorbic acid and CaCl(2) were effective on preserving or improving nutritional properties (phenolics, ascorbic acid, DPPH, and ABTS) mainly in the first 4 days of shelf life. The CaCl(2) had a further beneficial effect until 8 shelf life days. It is suggested that CaCl(2) is better in keeping overall quality through 8 days of shelf life at 2 degrees C in fresh-cut kiwifruit followed by Asc, and 1-MCP has negligible effect in the conditions of this experiment.

    The interaction of electromagnetic waves of wavelength lambda with periodic structures of spatial period lambda are studied. The emphasis of the work is on Bragg interactions where lambda approximately equal to 2 lambda/N and the Bragg order N takes on the values 1, 2,.... An extended coupled waves (ECW) theory is developed for the case N greater or equal to 2 and the results of the theory are found to compare favorably with the exact results of Floquet theory. Numerous numerical results are displayed as Brillouin diagrams for the first few Bragg orders. Moreover, explicit expressions for coupling coefficients, bandgap shifts and bandgap widths are derived for singly periodic media. Particular note is taken of phase speeding effects.

    Background: Tuberculosis continues to be a pressing health problem in India. The Revised National Tuberculosis Programme (RNTCP), an application of Directly Observed Treatment Short-course (DOTS) in India, launched in 1997 needs continuous evaluation. Objective: To study the outcomes of treatment among the patients put on DOTS under RNTCP in Chandigarh, UT. Material & Methods: A Longitudinal study was conducted during 2004-2005 in 13 Microscopic centres (MC's) spread over 2 Tuberculosis Units (TU's) under District Tuberculosis Centre (DTC) in Union Territory (UT), Chandigarh. A sample of 265 respondents, selected by two-stage stratified random sampling technique, was recruited in the study cohort. Data analysis was done using SPSS-10 statistical software package. Results: For Category I and Category II patients, the Success rate was 98.6% and 90.4% respectively. The overall default rate was 1.1% and failure rate was 2.6%. For re-treatment cases, failure rate was higher i.e. 5.8%. The sputum conversion rate among the new smear positive cases was 93.8% at 3 months of treatment. For the re-treatment cases, spu-tum conversion rate at 3 months was 94.1%. Conclusion: The study concludes that RNTCP is running successfully in UT Chandigarh, having high success rate and low default rate. The reasons for high failure rate should be explored in depth.
