ABSTRACT

INTRODUCTION: Approximately 21% of Germany's inhabitants have been born abroad or are of direct descent of immigrants. A positive birth experience has an effect on a woman's mental health and her future family planning choices. While international studies showed that immigrant women are less satisfied with their birth experience, no such study has been conducted in Germany until now. METHODS: At our center of tertiary care in Berlin, with approximately 50% immigrants among patients, pregnant women of at least 18 years of age were offered participation in this study. A modified version of the Migrant Friendly Maternity Care Questionnaire (MFMCQ) designed by Gagnon et al. in German, English, French, Spanish, Arabic and Turkish was used. We compared non-immigrant women to immigrant women and women with direct descent of immigrants. For certain analysis, the latter two groups were included together under the category "migration background". RESULTS: During the study period, 184 non-immigrant, 214 immigrant women and 62 direct descendants of immigrants were included. The most frequent countries of origin were Syria (19%), Turkey (17%), and Lebanon (9%). We found a slight difference between groups regarding age (non-immigrants: mean 33 years versus women with any migration background: mean 31) as well as parity with more non-immigrants delivering their first child. No difference in the satisfaction with care was observed between immigrant and any migration background groups (p ≥ 0.093 in the two-sided Fisher's exact test). At least 75.8% of all participating women reported complete satisfaction with care during labor, birth and after birth. Interestingly, the level of German language proficiency did not influence the immigrant patient's satisfaction with care. CONCLUSION: The study results show no difference regarding overall satisfaction with care during labor and birth despite a relevant language barrier. We are for the first time providing the MFMCQ in German and Turkish. Further future analyses on the impact of patient expectations on satisfaction with care will be conducted.

ABSTRACT

Chemical investigation of a sample of propolis originating from North-Western Cameroon led to the isolation of thirteen alk(en)ylphenols (1-13) (inseparable mixture) along with α-amyrin (14), ß-amyrin (15), lupeol (16), cycloartenol (17), mangiferonic acid (18), ambonic acid (19), mangiferolic acid (20), ambolic acid (21), isomangiferolic acid (22) and nine alk(en)ylresorcinols (23-31) (inseparable mixture). All compounds were identified following analysis of their spectroscopic data and comparison with previously published reports. Compounds (8), (12), (13) and (30) are new natural products. GC-MS analysis carried out on the alk(en)ylphenol and alk(en)ylresorcinol mixtures (dimethyl disulphide trimethylsilyl derivatives) revealed the presence of saturated and mono-unsaturated compounds with side chain lengths ranging from C11 to C19 and C15 to C19, respectively. The position of the double bond in mono-unsaturated derivatives was established from the characteristic fragments resulting from the cleavage of the bond between the two methylthio-substituted carbons. The most abundant compound in each mixture was 3-(12'Z-heptadecenyl)-phenol (10) and 5-(12'Z-heptadecenyl)-resorcinol (29). This study is the first to report the presence of triterpenes (except for lupeol) and phenolic lipids, including eighteen compounds previously unreported in bee glue, in an African sample.

ABSTRACT

Propolis is a widely used natural remedy and a range of biological activities have been attributed to it. The chemical composition of propolis is highly variable and its quality is often controlled on the basis of one or two marker compounds. In order to progress towards a method for the quality control of this complex material, HPLC and 1H-NMR approaches as methods of quality control have been compared. HPLC analyses of 43 samples of propolis were carried out and six marker compounds were quantified in each sample. The same samples were analysed using 1H-NMR and the spectra were then converted into their first derivative forms and digitised using the software application MestRe-C. The digitised data were subjected to principal component analysis using the software application Simca-P. It was found that the chemical composition of propolis mapped well according to the geographical origins of the samples studied when the first three principal components were used to display them. In addition, each sample was assessed for anti-oxidant activity, and the results were then overlaid onto the sample groupings according to 1H-NMR data. It was observed that anti-oxidant properties also mapped quite well according to geographical origin.

ABSTRACT

There is a genetic contribution to the idiopathic restless legs syndrome (iRLS). An autosomal dominant mode of inheritance is suspected, but as yet no gene has been identified. To assess the frequency and characteristics of the hereditary restless legs syndrome (RLS) in comparison to those of non-hereditary RLS, we analysed the clinical data of 300 RLS patients. All 300 patients diagnosed as RLS according to the criteria of the International RLS Study Group were examined using a standard questionnaire covering demographic data, family history, clinical symptoms, subjective sleep disturbances and course of the disease. In all patients a complete neurological examination was performed, and in selected cases electrophysiological examinations and polysomnographic studies. Family history was rated as definitely positive when at least one first-degree relative was examined and classified as RLS according to the criteria by one of the authors. If it proved impossible to contact family members to verify reports of a family history, the patients were classified as only having a "possible positive family history." 232 of the 300 patients had iRLS and 68 secondary RLS due to uremia (uRLS). 42.3% of the patients with iRLS and 11.7% of those with uRLS were classified as having "definite positive" hereditary RLS, with a further 12.6% of iRLS patients and 5.8% of uRLS patients as having "possible positive" hereditary RLS. Patients with definite hereditary RLS were significantly younger at the age of onset than those with a negative family history (35.45 vs. 47.17 years, p < 0.05). The clinical characteristics of the disease were similar in both groups, except that women with hereditary RLS experienced a worsening of symptoms during pregnancy (19.1% vs. 2.6%, p < 0.05). Our study shows that patients with hereditary RLS may experience an earlier onset of the disease. Hereditary and non-hereditary RLS present with similiar clinical signs and symptoms.

ABSTRACT

STUDY OBJECTIVE: To assess and compare polygraphic sleep measures and periodic leg movement (PLM) patterns in untreated patients with mild to moderate Parkinson's disease (PD), multiple system atrophy (MSA) and healthy age-matched controls. DESIGN: Polysomnographic recordings of 2 consecutive nights were performed in 10 patients with PD (mean age 65 years, mean Hoehn and Yahr stage 2.2), 10 patients with MSA (mean age 61 years) and in a control group of 10 healthy subjects (mean age 64 years). All patients and controls were free of antiparkinsonian medication and other centrally active drugs for 2 weeks prior to polysomnography. SETTING: NA. PATIENTS OR PARTICIPANTS: NA. INTERVENTIONS: NA. RESULTS: Sleep measures for the second night showed a significantly lower total sleep time, sleep efficiency and sleep period time in PD and MSA patients compared to healthy controls. PLM-indices during sleep and wakefulness were significantly higher in PD, but not in MSA patients compared to controls. Five patients with PD and 7 patients with MSA, but no control subject, showed abnormal rapid eye movement (REM) sleep features (i.e., REM sleep without atonia or behavioral manifestations typical for REM sleep behavior disorder). CONCLUSIONS: Sleep disruption and increased motor activity during REM and non REM sleep are a frequent finding in PD and MSA. An increased PLM index in untreated PD patients may be due to a dopaminergic deficit and is probably not associated with dopaminergic treatment.

ABSTRACT

From the European plant Ballota nigra L. various polyphenols including phenylpropanoid derivatives were isolated. There is increasing evidence that oxidized low-density lipoproteins (Ox-LDL) might be involved in the pathogenesis of atherosclerosis and it has been reported that polyphenols inhibit LDL peroxidation and atherogenesis. The goal of this study was to test whether the major polyphenolic compounds extracted from Ballota nigra, four phenylpropanoid glycosides, verbascoside, forsythoside B, arenarioside, and ballotetroside and one non-glycosidic phenylpropanoid, caffeoyl-L-malic acid, inhibit Cu(2+)-induced LDL peroxidation. The effectiveness of these compounds was compared to the activity of quercetin, a well-known polyphenol inhibitor of Cu(2+)-induced LDL oxidation. Antioxidant efficacious doses (ED 50) of arenarioside and ballotetroside were 1.8 microM and 7.5 microM respectively, while in the same conditions, the ED 50 of forsythoside B and verbascoside were similar (1 microM) and those of quercetin and of caffeoyl-L-malic acid were 2.3 microM and 9.5 microM respectively. Spectrophotometric studies show that quercetin is a Cu(2+) chelator while phenylpropanoid glycosides and caffeoyl-L-malic acid are not Cu(2+) chelators. Therefore, phenylpropanoid glycosides are strong inhibitors of Cu(2+)-induced LDL oxidation, independent of any capacity to act as Cu(2+) chelators.

ABSTRACT

Ballota nigra is a European plant known for its neurosedative properties. In this study, the ability of five phenylpropanoids (verbascoside, forsythoside B, arenarioside, ballotetroside, and caffeoyl malic acid) isolated from a hydroalcoholic extract, to bind to benzodiazepine, dopaminergic, and morphinic receptors was investigated. To carry out these studies, affinity tests with rat striata, entire brains and receptor rich preparations were employed. In addition, the phenolic aspect of these five phenylpropanoid esters led to investigate antioxidant activities using cell-free experiments and cellular experiments including isolated polymorphonuclear neutrophils (PMN). Effects of phenylpropanoid esters against reactive oxygen species as superoxide anion, peroxide hydrogen, hypochlorous acid and hydroxyl radical were tested. These molecules are liberated by PMN during inflammatory disorders, so that reproduction of this process in vitro stimulating PMN by chemical stimulants was undertaken. Results show that four of the five compounds are able to bind to the studied receptors. Inhibitory concentrations at 50% were determined and vary from 0.4 to 4.7 mg/ml. This may be in relation with the Ballota nigra known neurosedative activities. Results concerning antioxidant investigations evidence an ability to scavenge reactive oxygen species. Inhibitory concentrations at 50% obtained are comparable to those of known antioxidant drugs (mesna or N-acetyl cysteine). Moreover, the use of different stimuli having various pathways of action on PMN oxidative metabolism permits to establish that each phenylpropanoid ester has its own particular way of action by using proteine kinase C or phospholipase C pathways.

ABSTRACT

A reinvestigation of the stem bark of Cleistopholis glauca yielded 14 compounds, of which seven were either novel or had not been previously reported from this species. These were identified as the farnesane sesquiterpene methyl-(2E,6E)-10-oxo-3,7, 11-trimethyl-dodeca-2,6-dienoate (1); the azaanthracene alkaloid cleistopholine (4); two partially acetylated oligorhamnoside derivatives, 1-O-dodecanyl-2,3, 4-tri-O-acetyl-alpha-rhamnopyranosyl-(1-->3)-2, 4-di-O-acetyl-alpha-rhamnopyranosyl-(1-->3)-4-O-acetyl-alpha-rhamnopy ranosyl-(1-->4)-alpha-rhamnopyranoside (6) and 1-O-dodecanyl-2, 4-di-O-acetyl-alpha-rhamnopyranosyl-(1-->3)-2, 4-di-O-acetyl-alpha-rhamnopyranosyl-(1-->3)-4-O-acetyl-alpha-rhamnopy ranosyl-(1-->4)-alpha-rhamnopyranoside (8), for which the trivial names cleistetroside-7 and cleistetroside-6 were assigned, respectively; the dihydrobenzofuran neolignan rel-(2alpha, 3beta)-7-O-methylcedrusin (12); and the flavonoids dihydroquercetin (13) and quercetin (14). Structure assignments of all compounds were established by spectroscopic methods and comparison with published data. The chemosystematic significance of the occurrence of the isolated components is mentioned. Compounds 1, 6, and 8 are novel natural products.

ABSTRACT

The aerial parts of Goniothalamus gardneri (Annonaceae) has yielded the known flavonoids 2'-hydroxy-4,4',6'-trimethoxychalcone (flavokawain A), 2',4'-dihydroxy-4,6'-dimethoxydihydrochalcone, 4,2',4'-trihydroxy-6'-methoxydihydrochalcone, 5,7,4'-trimethoxyflavanone (naringenin trimethyl ether) and 7-hydroxy-5,4'-dimethoxyflavanone (tsugafolin) together with three novel compounds, the dimer characterised as (rel)-1beta,2alpha-di-(2,4-dihydroxy-6-methoxybenzoyl)-3beta,4alpha-di-(4-methoxyphenyl)-cyclobutane, 2',4'-dihydroxy-4,6'-dimethoxychalcone and 2'-hydroxy-4,4',6'-trimethoxydihydrochalcone. The last two have previously been synthesised but appear to be new natural products. A similar study of the aerial parts of G. thwaitesii led only to the isolation of the known flavonoids myricetin 4'-O-methyl ether-3-O-alpha-L-rhamnopyranoside (mearnsitrin) and myricetin-3-O-methyl ether (annulatin), together with the triterpenes friedelinol, friedelin and betulinic acid. All compounds were identified by spectroscopic analysis and, for known compounds, by comparison with published data.

ABSTRACT

Three new partially acetylated derivatives of 1-O-dodecanyl-alpha-L- rhamnopyranosyl-(1-->3)-alpha-L-rhamnopyranosyl-(1-->3)-alpha-L- rhamnopyranoside and three partially acetylated derivatives of 1-O-dodecanyl-alpha-L-rhamnopyranosyl-(1-->3)- alpha-L-rhamnopyranosyl-(1-->3)-alpha-L-rhamnopyranosyl-(1-->4)- alpha-L-rhamnopyranoside, one of them new, have been isolated from the mature leaves of Cleistopholis patens (Annonaceae). Their structures, elucidated by using COSY, COSY-LR, TOCSY and FAB mass spectrometry, have been characterised as cleistrioside-2, -3, -4 and cleistetroside-1, -2 and -6. From the same source, shikimic acid was also isolated.

ABSTRACT

OBJECTIVE: To investigate whether a combination treatment of regular-release levodopa (rr-L-dopa) and sustained-release levodopa (sr-L-dopa) compared with monotherapy of rr-L-dopa improves sleep quality and reduces periodic limb movements (PLM) in patients with restless legs syndrome (RLS) and problems with maintaining sleep. BACKGROUND: Reappearance of RLS symptoms during the second half of the night while being treated with rr-L-dopa is a common problem in the treatment of sleep disturbances caused by RLS. METHODS: A randomized, controlled, double-blind crossover trial was undertaken. Eligible patients fulfilled the diagnostic criteria of the International RLS Study Group, and met an actigraphically confirmed higher number of PLM per hour time in bed (PLM index) during the second half compared with the first half of the night under treatment with rr-L-dopa. During the crossover periods the patients received 100 to 200 mg rr-L-dopa plus either placebo or 100 to 200 mg sr-L-dopa at bedtime for 4 weeks each period. RESULTS: Thirty patients with RLS (11 men and 19 women) were assessed by actigraphy and subjective sleep quality, and showed a significant improvement in PLM index (p < 0.0001), in "time in bed without movements" (p < 0.0001), and in subjective sleep quality (p < 0.001). Eight of 30 patients reported an altered pattern of RLS symptoms, characterized by a time shift of RLS symptoms into the afternoon or evening, five of these during monotherapy with rr-L-dopa. CONCLUSIONS: A combination therapy of rr-L-dopa and sr-L-dopa is better than monotherapy with rr-L-dopa in reducing the frequency of PLM and problems maintaining sleep, even in patients who are severely affected.

ABSTRACT

In addition to the previously isolated phenylpropanoid glycosides verbascoside 1, forsythoside B 2, arenarioside 3 and ballotetroside 4, another four compounds were isolated from generative aerial parts of Ballota nigra: three phenylpropanoid glycosides, alyssonoside 5, lavandulifolioside 6 and angoroside A 7 and a non-glycosidic derivative (+)-(E)-caffeoyl-L-malic acid 8. The antibacterial activity of the five major compounds (1-4 and 8) was tested against gram-positive and gram-negative bacteria. Three of them (1-3) exhibited a moderate antimicrobial activity against Proteus mirabilis and Staphylococcus aureus including one methicillin-resistant strain.

ABSTRACT

A preliminary survey of the botanical characters of the species Ballota nigra and of its subspecies is reported. Phytochemical investigation of the flowered aerial parts led us to isolation and structural elucidation of one diterpene (13-hydroxyballonigrinolide) and four phenylpropanoid glycosides reported for the first time from the genus Ballota: verbascoside, forsythoside B, arenarioside and ballotetroside. These compounds appear to be characteristic of this species and could be used for the standardization of the drug. Moreover, the four phenylpropanoid glycosides isolated could justify the use of Ballota nigra as a neurosedative drug.

ABSTRACT

The restless legs syndrome (RLS) is one of the most common and unpleasant complaints of uremic patients. The pathophysiology of the RLS is still unclear. Various factors, including anemia and iron deficiency, are proposed to play a major role. We determined the prevalence of RLS in all stable hemodialysis patients under long-term treatment in two dialysis centers (n = 136) and compared the clinical and biochemical findings of patients with RLS and without RLS. Twenty-three percent of all patients investigated fulfilled the diagnostic criteria of RLS according to the International Restless Legs Syndrome Study Group. There were no statistical differences between the two groups regarding age, duration of uremia and need for dialysis, time on dialysis per week, hemoglobin, hematocrit, erythrocytes, s-ferritin, s-transferrin, s-iron, calcium, and standard biochemical indices, except for intact parathyroid hormone (iPTH) levels. Uremic patients with RLS showed significantly lower iPTH (P < 0.01) concentrations. In addition, the RLS group received a significantly higher number and dosage of psychopharmacological drugs, (ie, L-DOPA), than patients without RLS. These biochemical findings suggest that neither the severity of anemia nor that of iron deficiency has to be considered a major pathophysiological factor in established RLS. The significantly lower iPTH secretion in uremic patients with RLS, however, is a new finding, and further investigations will be necessary to determine whether this result is of any clinical significance to this group of patients. The significantly higher number of psychopharmacological drugs prescribed to uremic patients with RLS may be related to the symptoms of RLS.

ABSTRACT

A new phenylpropanoid glycoside, ballotetroside, has been isolated from the aerial parts of Ballota nigra. On the basis of chemical and spectral data, its structure has been established as (3,4-dihydroxyphenyl)-2-ethyl[alpha-L-arabinopyranosyl-(1-->2)-alp ha- L-rhamnopyranosyl-(1-->3)]-beta-D-apiofuranosyl-(1-->6)-4-O- caffeoyl-beta-D-glucopyranoside.

ABSTRACT

Idiopathic restless legs syndrome (RLS) frequently follows an autosomal dominant inheritance with a variable clinical expressivity of symptoms. We describe the largest German kindred of familial RLS with 20 affected and investigated members in four generations with a variety of clinical symptoms. Patients were examined clinically, and polysomnography was performed in selected cases. The diagnosis was set according to the diagnostic criteria of the International RLS Study Group. All patients showed sensory symptoms of their legs and a worsening of symptoms with increasing age. Older patients, who needed treatment, responded well to opioids. Segregation ratios were close to 0.5, confirming a virtually complete penetrance. The mean age of onset fell from 51.5 years in the second generation to 19.8 years in the fourth generation (ANOVA, p = 0.025). The identification of presymptomatic carriers in the fourth generation in the following years, however, may prejudice this result. This large family showed the variety of clinical RLS symptoms with decreasing age of onset in generations II-IV, suggesting at least the possibility of anticipation.
