Treatment of acute bronchitis with a liquid herbal drug preparation from Pelargonium sidoides (EPs 7630): a randomised, double-blind, placebo-controlled, multicentre study

ABSTRACT Objective: The objective of this study was to examine the efficacy and safety of a herbal drug preparation from the roots of Pelargonium sidoides (EPs* 7630) in the treatment of acute bronchitis in adults outside the very restricted indication for an antibiotic therapy. Research design and methods: This was a randomised, double-blind, placebo-controlled, multicentre study with 217 patients aged between 18 and 66 years with acute bronchitis. One hundred and eight patients were given 30 drops of EPs 7630-solution three times daily and 109 patients 30 drops of placebo three times daily for a period of 7 days. Main outcome measures: Individual change in bronchitis symptom score (BSS) over 7 days, individual symptoms, patient satisfaction and adverse events. Results: After 7 days of treatment, the BSS decreased by 7.6 ± 2.2 points in the EPs 7630 group and by 5.3 ± 3.2 points in the placebo group. The 95% confidence interval for the difference between the effects was calculated as 1.6–3.1, showing highly significant superiority for the EPs 7630 treatment ( p < 0.0001). There were also marked improvements in the individual symptoms, which are the components of BSS – cough, chest pain on coughing, sputum, rales/rhonchi and dyspnoea – in the treatment group, relative to placebo. Patient satisfaction was very good. Only minor and transitory adverse events were recorded. No serious adverse events occurred during the trial. Conclusion: EPs 7630-solution is a well tolerated and effective treatment for acute bronchitis in adults outside the very restricted indication for an antibiotic therapy.
Carotid artery web and ischemic stroke

Objective: To determine whether there is an association between carotid artery web and ischemic stroke. Methods: This was a single-center, age- and sex-matched, case-control study. Cases were consecutive patients with anterior circulation ischemic stroke of undetermined etiology (Trial of Org 10172 in Acute Stroke Treatment [TOAST] classification). Controls were consecutive patients with cerebral aneurysms, arteriovenous malformations, or primary intracerebral hemorrhages. Additional inclusion criteria were age <60 years and CT angiography of the neck. Two neuroradiologists diagnosed webs according to previously published criteria. One neuroradiologist also assessed for nonstenotic atherosclerotic plaque (carotid wall thickness ≥3 mm or intramural calcification). We used conditional logistic regression to estimate the odds ratio between carotid web and ischemic stroke and its 95% confidence interval. Results: Fifty-three of 62 cases (85%) were matched by age (within 1 year) and by sex to 102 controls. There was a carotid web in 4 of 53 cases (9.4%) vs 1 of 102 controls (1.0%, odds ratio = 8.0, 95% confidence interval = 1.2–67, p = 0.032). There was no significant difference in the prevalence of nonstenotic carotid atherosclerotic plaque between the case and control groups. There was agreement on diagnosis of web for 163 of 164 patients (99%) and 7 of 8 webs (88%), and the Cohen κ for interobserver agreement was 0.93. Conclusions: There is an association between carotid artery web and ischemic stroke in patients who lack an alternative cause of stroke. Carotid web may be an underappreciated risk factor for stroke.
Physically violent behaviour in dementia care: Characteristics of residents and management of violent situations

Objective: Physically violent behaviour (PVB) is common among residents with dementia and often complicates nursing care. This study aims to explore types of caring situations, resident characteristics related to PVB and professional caregivers’ management of PVB. Methods: The study included 40 group homes for 309 residents with dementia. Data was gathered by means of structured interviews, the Multi-Dimensional Dementia Assessment Scale and the Geriatric Rating Scale. Results: Ninety-eight of the residents (31.7%) were assessed as showing PVB during the preceding week. Three factors were independently associated with PVB: male gender, antipsychotic treatment and decline in orientation. Violent residents were more likely to have impaired speech, difficulties understanding verbal communication and prescribed analgesics and antipsychotics than were non-violent residents. PVB occurred mainly in intimate helping situations and was managed by symptom-oriented approaches, such as distraction, medication and isolation. The working team also held frequent discussions about the residents with PVB. Conclusion: This study shows that PVB is frequently displayed among residents in group homes for persons with dementia and the caregivers mainly manage PVB in a symptom-oriented way. To enhance the quality of care for patients with dementia, there is a need for interventions that aim to understand and manage the residents’ physical violent behaviour.
Prevalence of obesity, diabetes, and obesity-related health risk factors, 2001.

CONTEXT Obesity and diabetes are increasing in the United States. OBJECTIVE To estimate the prevalence of obesity and diabetes among US adults in 2001. DESIGN, SETTING, AND PARTICIPANTS Random-digit telephone survey of 195 005 adults aged 18 years or older residing in all states participating in the Behavioral Risk Factor Surveillance System in 2001. MAIN OUTCOME MEASURES Body mass index, based on self-reported weight and height and self-reported diabetes. RESULTS In 2001 the prevalence of obesity (BMI > or =30) was 20.9% vs 19.8% in 2000, an increase of 5.6%. The prevalence of diabetes increased to 7.9% vs 7.3% in 2000, an increase of 8.2%. The prevalence of BMI of 40 or higher in 2001 was 2.3%. Overweight and obesity were significantly associated with diabetes, high blood pressure, high cholesterol, asthma, arthritis, and poor health status. Compared with adults with normal weight, adults with a BMI of 40 or higher had an odds ratio (OR) of 7.37 (95% confidence interval [CI], 6.39-8.50) for diagnosed diabetes, 6.38 (95% CI, 5.67-7.17) for high blood pressure, 1.88 (95% CI,1.67-2.13) for high cholesterol levels, 2.72 (95% CI, 2.38-3.12) for asthma, 4.41 (95% CI, 3.91-4.97) for arthritis, and 4.19 (95% CI, 3.68-4.76) for fair or poor health. CONCLUSIONS Increases in obesity and diabetes among US adults continue in both sexes, all ages, all races, all educational levels, and all smoking levels. Obesity is strongly associated with several major health risk factors.
Pretreatment of lignocellulosic materials with hydrogen peroxide in presence of manganese compounds

Pretreatment of lignocellulosic materials such as newspaper, rice straw, pulp waste, and municipal solid waste with hydrogen peroxide in the presence of manganese compounds greatly enhances their susceptibility to enzymatic saccharification. This pretreatment can be achieved using rather mild conditions with only a minimal decrease in the recovery and little change in composition. Manganese salts in this hydrogen peroxide pretreatment works effectively in particular when the concentration of hydrogen peroxide is relatively low. The susceptibility of hydrogen‐peroxide‐pretreated substrate to enzymatic saccharification increases with increasing the molar ratio of manganes to hydrogen peroxide up to 1 : 100.
Anterior vena caval oxygen profiles in a deep-diving California sea lion: arteriovenous shunts, a central venous oxygen store and oxygenation during lung collapse

ABSTRACT Deep-diving California sea lions (Zalophus californianus) can maintain arterial hemoglobin saturation (SO2) above 90% despite lung collapse (lack of gas exchange) and extremely low posterior vena caval SO2 in the middle of the dive. We investigated anterior vena caval PO2 and SO2 during dives of an adult female sea lion to investigate two hypotheses: (1) posterior vena caval SO2 is not representative of the entire venous oxygen store and (2) a well-oxygenated (arterialized) central venous oxygen reservoir might account for maintenance of arterial SO2 during lung collapse. During deep dives, initial anterior vena caval SO2 was elevated at 83.6±8.4% (n=102), presumably owing to arteriovenous shunting. It remained high until the bottom phase of the dive and then decreased during ascent, whereas previously determined posterior vena caval SO2 declined during descent and then often increased during ascent. These divergent patterns confirmed that posterior vena caval SO2 was not representative of the entire venous oxygen store. Prior to and early during descent of deep dives, the high SO2 values of both the anterior and posterior venae cavae may enhance arterialization of a central venous oxygen store. However, anterior vena caval SO2 values at depths beyond lung collapse reached levels as low as 40%, making it unlikely that even a completely arterialized central venous oxygen store could account for maintenance of high arterial SO2. These findings suggest that maintenance of high arterial SO2 during deep dives is due to persistence of some gas exchange at depths beyond presumed lung collapse. Summary: Arterialization of venous blood does not account for maintenance of aortic oxygenation during lung collapse in deep-diving sea lions.
Frequency of Magnetic Resonance Imaging Abnormalities in Patients With Migraine

Background. ‐The frequency of magnetic resonance imaging (MRI) abnormalities in patients with migraine has been reported at 12% to 46%. We examined a series of patients to determine the frequency of MRI abnormalities, and any relationship of frequency with patient age, sex, migraine type, duration of symptoms, and other medical conditions.
Mucopolysaccharidosis type IIID: 12 new patients and 15 novel mutations b

Mucopolysaccharidosis III D (Sanfilippo disease type D, MPS IIID) is a rare autosomal recessive lysosomal storage disorder previously described in only 20 patients. MPS IIID is caused by a deficiency of N‐acetylglucosamine‐6‐sulphate sulphatase (GNS), one of the enzymes required for the degradation of heparan sulphate. So far only seven mutations in the GNS gene have been reported. The clinical phenotype of 12 new MPS IIID patients from 10 families was studied. Mutation analysis of GNS was performed in 16 patients (14 index cases). Clinical signs and symptoms of the MPS IIID patients appeared to be similar to previously described patients with MPS III. Early development was normal with onset of behavioral problems around the age of 4 years, followed by developmental stagnation, deterioration of verbal communication and subsequent deterioration of motor functions. Sequence analysis of the coding regions of the gene encoding GNS (GNS) resulted in the identification of 15 novel mutations: 3 missense mutations, 1 nonsense mutation, 4 splice site mutations, 3 frame shift mutations, 3 large deletions and 1 in‐frame small deletion. They include the first missense mutations and a relatively high proportion of large rearrangements, which warrants the inclusion of quantitative techniques in routine mutation screening of the GNS gene. © 2010 Wiley‐Liss, Inc.
Regulation of polymorphonuclear leukocyte membrane fluidity: effect of cytoskeletal modification

We previously demonstrated that the f‐actin cytoskeleton modulates oxygen radical production associated with polymorphonuclear leukocyte (PMN) oxidative burst activity. Given the close association of the actin and microtubule cytoskeletons with the plasma membrane and the transmembrane location of the PMN NADPH oxidase, it is likely cytoskeletal change may affect PMN membrane responses, such as cellular anisotropy. Changes in PMN membrane fluidity were therefore examined after PMN activation by the chemoattractant N‐formyl‐1‐methionyl‐1‐leucyl‐1‐phenylalanine (fMLP) in the presence or absence of phalloidin or cytochalasin B (CB), agents that stabilize and disrupt f‐actin, or taxol and vincristine, which stabilize and disrupt microtubules, respectively. Phalloidin and taxol treatment of PMN significantly decreased whereas CB and vincristine significantly increased membrane fluidity. Activation of PMN by fMLP (10‐6 M) resulted in a significant increase in membrane fluidity that was attenuated by PMN pretreatment with phalloidin or taxol. CB and vincristine pretreatment of PMN did not alter the fMLP response. These data suggest that stabilization of the f‐actin or microtubule cytoskdeton may prevent increases in cellular membrane fluidity associated with PMN activation. —J. Leukoc.

Neurons of origin of the internal ramus of the rabbit accessory nerve: Localization in the dorsal nucleus of the vagus nerve and the nucleus retroambigualis

The neurons of origin of the internal ramus of the rabbit accessory nerve were identified in the dorsal nucleus of the vagus nerve, using bilateral injections of horseradish peroxidase into the inferior vagal ganglion, soft palate, and pharynx, which were preceded by different combinations of the unilateral intracranial severings of the rootlets of the vagus and glossopharyngeal nerves, those of the cranial root of the accessory nerve, and the trunk of its spinal root. The neurons of origin occupied the caudal four‐fifths of the dorsal vagal nucleus extending from about 1.0 mm rostral to the obex as far caudally as the second cervical spinal segment, with their number being about half the total number of neurons of the nucleus. Although considerably fewer, they were also located in the nucleus retroambigualis of the first cervical spinal segment and the second segment. Axons of most internal ramus neurons traversed the rootlets of the cranial accessory root. Axons of the few neurons located more caudally than about 1.0 mm caudal to the obex emerged from the upper cervical spinal cord to run along the trunk of the spinal accessory root before finally joining the internal ramus; caudal to the midlevel of the first cervical segment, the dorsal vagal nucleus and the nucleus retroambigualis contained neurons whose axons followed only that course.
Service experiences in hospitals in Bangladesh: are there gender inequities?

PURPOSE The disparities faced by women, especially in Bangladesh, have a long and contentious history. From education and employment to health care and other social products, the marginalization of women has been stark. This paper aims to examine whether women experience poorer services than men in the hospitals in Bangladesh. DESIGN/METHODOLOGY/APPROACH A survey was conducted in both public and private hospitals in Dhaka City, Bangladesh. The sample comprised 305 randomly selected respondents. Using statistical and data mining techniques, the authors test the hypothesis and identify interesting data patterns. FINDINGS Surprisingly, very few differences were found between the service experiences of male and female patients. While the literature would predict differently, given the disparities that women generally experience, on most service quality attributes female patients were at least as well-served as male patients. RESEARCH LIMITATIONS/IMPLICATIONS The findings may be unique to the sample from the capital city where hospital users may be more affluent and are provided better service without gender inequity. PRACTICAL IMPLICATIONS The findings raise intriguing questions. Among the various possibilities the authors surmise the following: there may be deeper systemic changes underway that are reflected in service providers' attitudes toward women. It is possible that women have lower expectations from the service providers; thus, their ratings are at par with those of men even if they actually received poorer services. ORIGINALITY/VALUE This is probably a unique study in that it focuses on gender effects on perceived service quality in a hospital setting in Bangladesh.
Effect of Veillonella parvula on the antimicrobial resistance and gene expression of Streptococcus mutans grown in a dual-species biofilm.

INTRODUCTION Our previous studies showed that Streptococcus mutans and Veillonella parvula dual-species biofilms have a different acid production profile and a higher resistance to chlorhexidine than their single-species counterparts. The aim of the current study was to test whether the susceptibility of S. mutans grown in the presence of V. parvula is also decreased when it is exposed to various other antimicrobials. Furthermore, the aim was to identify other changes in the physiology of S. mutans when V. parvula was present using transcriptomics. METHODS Susceptibility to antimicrobials was assessed in killing experiments. Transcript levels in S. mutans were measured with the help of S. mutans microarrays. RESULTS When V. parvula was present, S. mutans showed an increase in survival after exposure to various antimicrobials. Furthermore, this co-existence altered the physiology of S. mutans. The expression of genes coding for proteins involved in amino acid synthesis, the signal recognition particle-translocation pathway, purine metabolism, intracellular polysaccharide synthesis, and protein synthesis all changed. CONCLUSION Growing in a biofilm together with a non-pathogenic bacterium like V. parvula changes the physiology of S. mutans, and gives this bacterium an advantage in surviving antimicrobial treatment. Thus, the study of pathogens implicated in polymicrobial diseases, such as caries and periodontitis, should be focused more on multispecies biofilms. In addition, the testing of susceptibility to currently used and new antimicrobials should be performed on a multispecies microbial community rather than with single pathogens.
Effects of diuretic-induced hypovolemia/isosmotic dehydration on cardiorespiratory responses to hyperthermia and its physical treatment in rabbits

Under conditions of heat stress and hyperosmotic dehydration, both animals and humans reduce thermoregulatory evaporation and regulate deep body temperature at elevated levels. Regarding the mechanisms, the main role in producing these thermoregulatory changes during dehydration is attributed to the increased osmolality of body fluids, although the role of the decreased plasma volume without changes in plasma osmolality (hypovolemia/isosmotic dehydration) has not been so far investigated. There are also controversial experimental results regarding the effects of dehydration on heat stress-induced cutaneous vasodilation. Therefore, this paper studied the effects of hypovolemia/isosmotic dehydration on cardiorespiratory responses to hyperthermia and its physical treatment in 17 anaesthetized adult rabbits. The animals were divided into two groups: normovolemic group (NV; n = 10) and hypovolemic group (HV; n = 7). In the HV group, hypovolemia/isosmotic dehydration (decrease in plasma volume by 16.1 ± 1.2%) was induced by furosemide (5 mg kg−1 i.v.) without change in measured plasma Na+ concentration. Hyperthermia (the rise in body temperature (BT) to 42°C by a gradual body surface heating) caused significant increase in minute ventilation (VE) in both groups. However, VE values were significantly higher in the HV rabbits compared to the NV animals despite the lower breathing frequency (p < 0.05). The panting was absent in the HV rabbits at the BT of 42°C, unlike the NV animals. From cardiovascular variables, the vasoconstrictor response in visceral (mesenteric) region during hyperthermia in hypovolemic/isosmotic animals was attenuated (p < 0.05), whereas the heat stress-induced cutaneous vasodilation was not influenced by hypovolemia. Recovery of the BT by body surface cooling was accompanied by further increase in VE in the NV group, whereas VE decreased (p < 0.05) in the HV animals. Cooling led to recovery of the cardiovascular parameters. There were found no significant cardiorespiratory differences between the groups (NV:HV) during cooling. The lower frequency of breathing and attenuation of the mesenteric vasoconstriction during exogenous hyperthermia are present not only during hyperosmotic dehydration induced by water deprivation, but they also occur under conditions of furosemide-induced isosmotic dehydration/hypovolemia in rabbits. The heat stress-induced cutaneous vasodilation regarding its biological importance was not influenced by hypovolemia/isosmotic dehydration. Therefore, it is suggested that hypovolemia alone is sufficient to produce described respiratory, thermoregulatory and cardiovascular changes in dehydrated rabbits during exogenous hyperthermia, whereas hyperosmolality is not a requisite.
50 Hz magnetic field exposure influence on human performance and psychophysiological parameters: two double-blind experimental studies.

Two double-blind studies were performed to examine magnetic field (MF) exposure effects and to determine the impact of temporal variation (continuous vs. intermittent exposure) of 100 mu T(rms) 50 Hz MF diurnal exposure on psychological and psychophysiological parameters in healthy humans. Three cephalic exposure sessions of 30-min, i.e., sham, continuous, and intermittent (15 s ON/OFF cycles) MF conditions, were involved. Each subject participated in all sessions, which were spaced at 1-wk intervals. In each session, mood ratings and performance measures were obtained before, during, or after exposure and several electrophysiological data (event-related brain potentials [ERP]) were recorded after each exposure session. These criteria were chosen to evaluate sensory functions as well as automatic and voluntary attentional processes. In experiment 1, 21 healthy male volunteers (20 to 27 years of age) were studied. Ten subjects were exposed at 13:30 h, and 11 subjects were exposed at 16:30 h. Statistically significant changes in the amplitude of ERP were observed after MF exposure in the dichotic listening task, indexing selective attention processes. Eighteen of the 21 original male volunteers took part in experiment 2, undertaken to better understand the results related to information processing involved in selective attention and control for ultradian rhythmicity. Exposure time for all the subjects was at 13:30 h. The analysis of the data again revealed significant amplitude changes of the ERP recorded in the dichotic listening task. Moreover, they demonstrated ERP latency and reaction time slowing in the oddball paradigm, a visual discrimination task after real MF exposure. These results also indicate that a low level 50 Hz MF may have a slight influence on event-related potentials and reaction time under specific circumstances of sustained attention.
Crystal structure of 4-aminopyridinium 5-(5-chloro-2,4-dinitrophenyl)-1,3-dimethyl-2,6-dioxo-1,2,3,6-tetrahydropyrimidin-4-olate hemihydrate

In the title molecular salt, the two rings of the barbiturate anion are inclined to one another by 43.40 (3)°. In the crystal, the cations and anions are linked via N—H⋯O hydrogen bonds, forming zigzag chains along [10], which in turn are linked by O—H⋯O and C—H⋯O hydrogen bonds, forming slabs lying parallel to (10).
Subthalamic deep brain stimulation and impulse control in Parkinson’s disease

Background and purpose: Experimental studies suggest that deep brain stimulation (DBS) of the subthalamic nucleus (STN) induces impulsivity in patients with Parkinson’s disease (PD). The purpose of this study was to assess various measures of impulse control in PD patients with STN DBS in comparison to patients receiving medical therapy.
