ABSTRACT
Freezing of gait (FOG) is a heterogeneous symptom. Studies of treatment for FOG are scarce. Levodopa and monoamine oxidase inhibitors (rasagiline and selegiline) have shown effective improvement for FOG. Other drugs, such as L-threo-3, 4-dihydroxyphenylserine, amantadine, and botulinum toxin have exhibited some beneficial effects. The present review summarizes the potential drug treatment for FOG in Parkinsonism.

OBJECTIVES: Studies assessing emotional distress severity of paediatric oncology patients prior to reaching 5-year survivorship status have produced inconsistent findings. This cross-sectional multi-centre study aimed to determine psychological, demographic, illness and treatment risk factors for emotional distress in this population. METHODS: Paediatric oncology patients (n = 74), aged 12-18 years, completed the Paediatric Index of Emotional Distress, Self-Description Questionnaire and Paediatric Quality of Life Inventory. Seventy-two parents provided background information regarding demographics, diagnoses and treatment protocols in addition to appropriate proxy ratings. RESULTS: Hierarchical multiple regression analyses demonstrated that demographic, illness and treatment factors explained little variance in emotional distress. Global self-concept, global-generic and cancer-specific health-related quality of life (HRQOL) were significant predictors. Provisional multiple regression analyses indicated that pain/hurt, illness-related worries, communication difficulties and negative self-views in relation to math abilities, parent relations and opposite-sex peer relations were risk factors for emotional distress in this sample. Paired-sample t-tests and Pearson's moment-correlation coefficients showed patient and parent reports of patients' self-concepts and HRQOL were highly consistent. CONCLUSIONS: This study empirically identified modifiable psychological risk factors for emotional distress prior to 5-year survivorship status and provided guidance for future interventions. Furthermore, findings suggest that parent reports can provide reliable estimates of patients' self-concepts and HRQOL. Generalizability of the findings was enhanced by the diversity of the sample studied, in terms of diagnosis and treatment exposure, and the multi-centre recruitment strategy employed. Nevertheless, the findings should be corroborated by larger, longitudinal studies.

SUMMARY: Androgen deprivation therapy in 80 men was associated with declines in bone mineral density (BMD), which were greatest in the first year, and in the lumbar spine compared to controls. Vitamin D use was associated with improved BMD in the lumbar spine and in the first year. INTRODUCTION: Decreased BMD is a common side effect of androgen deprivation therapy (ADT), leading to increased risk of fractures. Although loss of BMD appears to be greatest within the first year of starting ADT, there are few long-term studies of change in BMD, and risk factors for bone loss are not well-characterized. METHODS: Men aged 50+ with nonmetastatic prostate cancer starting continuous ADT were enrolled in a prospective longitudinal study. BMD was determined by dual-energy x-ray absorptiometry at baseline and yearly for 3 years. Matched controls were men with prostate cancer not receiving ADT. Multivariable regression analysis examined predictors of BMD loss. RESULTS: Eighty ADT users and 80 controls were enrolled (mean age 69 years); 52.5 % had osteopenia and 8.1 % had osteoporosis at baseline. After 1 year, in adjusted models, ADT was associated with significant losses in lumbar spine BMD compared to controls (-2.57 %, p = 0.006), with a trend towards greater declines at the total hip (p = 0.09). BMD changes in years 2 and 3 were much smaller and not statistically different from controls. Use of vitamin D but not calcium was associated with improved BMD in the lumbar spine in year 1 (+6.19 %, p < 0.001) with smaller nonsignificant increases at other sites (+0.86 % femoral neck, +0.86 % total hip, p > 0.10) primarily in the first year. CONCLUSIONS: Loss of BMD associated with ADT is greatest at the lumbar spine and in the first year. Vitamin D but not calcium may be protective particularly in the first year of ADT use.

BACKGROUND/AIMS: The role of cognitive reserve in Parkinson's disease (PD)-mild cognitive impairment (MCI) is incompletely understood. METHODS: The relationships between PD-MCI, years of education, and estimated premorbid IQ were examined in 119 consecutive non-demented PD patients using logistic regression models. RESULTS: Higher education and IQ were associated with reduced odds of PD-MCI in univariate analysis. In multivariable analysis, a higher IQ was associated with a significantly decreased odds of PD-MCI, but education was not. CONCLUSION: The association of higher IQ and decreased odds of PD-MCI supports a role for cognitive reserve in PD, but further studies are needed to clarify the interaction of IQ and education and the impact of other contributors such as employment and hobbies.
ABSTRACT
Androgen deprivation therapy is commonly used to treat prostate cancer, but by lowering testosterone levels it may affect cognitive function. However, the relationship between testosterone and cognition remains unclear. We examined the relationship between sex hormones (total testosterone, bioavailable testosterone, and estradiol) and cognition in a cross-sectional study of 198 older men (mean age 69.2 years, median education 16 years) with and without prostate cancer, none of who had started androgen deprivation therapy. We found relationships between total testosterone and two of four measures of working memory. Similar relationships were found in regression analyses adjusted for age and education with both total testosterone and estradiol. Neither hormone was related to other cognitive domains, nor was bioavailable testosterone level. Although cognitive function was not generally related to sex hormone levels in older men, there may be a weak association with working memory. These results may help guide future studies.

The authors prospectively screened 297 patients with Parkinson disease (PD), who attended a tertiary clinic, using a modified South Oaks Gambling Scale. Lifetime prevalence of pathologic gambling (PG) was 3.4% and on any dopamine agonist was 7.2%. PG was associated with earlier PD onset and with dopamine agonists but not with agonist subtype or doses. We found no association with a potent D3 receptor agonist.

BACKGROUND: Several studies indicate semantic fluency more sensitively discriminates patients with Alzheimer disease (AD) from normal elderly persons, with disproportionate impairment of semantic over phonemic fluency. OBJECTIVE: To determine the ability of abbreviated fluency measures in the clinic setting (1-minute letter F and animal fluency tests) to detect AD, and to assess whether difference scores between these measures discriminate patients with AD and vascular dementia (VaD) from normal elderly persons. METHODS: The authors studied patients with AD (n = 98) meeting National Institute of Neurological Communicative Disorders and Stroke-Alzheimer's Disease and Related Disorders Association criteria, VaD patients (n = 18) meeting National Institute of Neurological Disorders and Stroke-Association Internationale pour la Recherche et l'Enseignement en Neurosciences criteria, cognitively impaired but not demented patients (CIND; n = 25), vascular CIND patients (VCIND; n = 24), and normal control subjects (NCs; n = 46). RESULTS: Analysis of covariance controlling for age, education, and overall impairment indicated all groups generated fewer animal names compared with NCs, whereas only VaD patients generated fewer letter F words compared with NCs. On standardized scores, patients with AD and CIND, unlike those with VCIND and VaD, scored significantly worse on the animal fluency test than on the letter F fluency test. The animal fluency test was superior in discriminating all patient groups from NCs. Positive likelihood ratios (PLRs) revealed animal fluency scores <15 were 20 times more likely in a patient with AD than in an NC (sensitivity = 0.88; specificity = 0.96). Letter F scores <4 discriminated VaD from AD patients (PLR = 4.0; sensitivity = 0.44; specificity = 0.90). Difference scores <0 (i.e., fewer animal than letter F words) discriminated patients with VCIND from those with CIND (PLR = 2.5; sensitivity = 0.32; specificity = 1.00). CONCLUSIONS: A 1-minute semantic fluency test can assist in early detection of dementia in the memory clinic setting.

Genetic factors are known to be important in the development of Hodgkin lymphoma (HL). Interleukin-10 (IL-10) secretion by both malignant and reactive cells is thought to be important in the pathogenesis of HL especially Epstein-Barr virus (EBV) positive cases. Polymorphisms of the IL-10 gene have been reported to be associated with susceptibility to EBV infection. The cytotoxic response to EBV is determined by a Th1 biased immune response which is characterised by interferon gamma (IFNgamma) secretion. We therefore investigated polymorphisms in the IL-10 (-1082 G/A and -592 C/A) and IFNgamma (intron 1 CA repeat) genes as predisposing factors in the development 147 cases of HL. A difference of borderline statistical significance was demonstrated for the IFNgamma gene polymorphism but significance was lost when analysis was restricted to the common genotypes. No significant differences in the distributions of genotypes were found for the IL-10 gene polymorphisms. IL-10 and IFNgamma levels were also measured on 26 patients with HL. No statistically significant differences were detected when the results were analysed by genotype. We found little evidence IL-10 and IFNgamma genotypes predispose to the development of HL or influence the inflammatory host response.

A cyclic AMP response element (CRE)-luciferase reporter gene assay was used to characterise the functional responses of human melatonin mt(1) and human melatonin MT(2) receptors, stably expressed in the human embryonic kidney cell line HEK293, to a series of six naphthalenic analogues of melatonin. By comparison to the observed melatonin-mediated inhibition of stimulated luciferase levels the naphthalenic series was identified as comprising agonists, partial agonists and one antagonist of melatonin mt(1) and melatonin MT(2) receptor function. Three of the agonist/partial agonist members of this series were also identified as displaying a functional selectivity for the melatonin MT(2) receptor. Competitive displacement of 2-[125I]iodomelatonin binding to the ovine pars tuberalis melatonin ML(1) receptor demonstrated a close correlation to the observed functional luciferase responses of the human melatonin mt(1) receptor. We conclude that the CRE-luciferase reporter gene assay provides an effective functional screening method for the pharmacological characterisation of human melatonin receptor subtypes.

Site-directed mutagenesis was used to study two residues, valine 208 and histidine 211, in transmembrane domain 5 of the ovine Mel1a beta melatonin receptor. A series of 4 mutants were constructed (V208A, V208L, H211F, H211L), and each engineered to contain a FLAG-epitope. Immunocytochemistry demonstrated that all the mutants were expressed in COS-7 cells at levels comparable to the FLAG-epitope tagged wild-type Mel1a beta receptor (approximately 120 fmol/mg protein). Ligand binding revealed however that all mutants had reduced affinities for 2-[125I]-iodomelatonin (Kd wild-type 139 pM, Kd mutants 320 to 989 pM). Competition studies, with a series of melatonin analogues, identified a probable interaction between histidine 211 and the 5-methoxy group of melatonin. The wild-type receptor and both valine 208 mutants displayed a dose-dependent melatonin mediated inhibition of cyclic AMP levels in HEK293 cells, with IC50 values in the same rank-order as their melatonin binding affinities. Both H211F and H211L, however, did not display any melatonin mediated effects and may suggest that histidine 211 is critical for melatonin mediated receptor activation.

Binding assays using 2-[125I]iodomelatonin revealed high-affinity, guanosine 5'-O-(3-thiotriphosphate) sensitive, melatonin binding sites (B(max) 1.1 fmol/mg protein) in the human embryonic kidney cell line HEK293. Competition studies using the selective melatonin receptor antagonist luzindole and RT-PCR techniques identified these sites as human Mel1a melatonin receptors. Challenge of HEK293 cells with 1 microM melatonin had no effect on forskolin stimulated cyclic AMP levels, whereas in HEK293 cells engineered to stably over-express the human Mel1a melatonin receptor (B(max) > 400 fmol/mg protein) melatonin dose-dependently inhibited stimulated cyclic AMP levels (IC50 7.7 pM). These data may indicate that certain tissues, expressing low levels of G protein-coupled melatonin receptors, do not display melatonin mediated inhibition of cAMP.

In the present studies we examined the regulation of insulin-like growth factor I (IGF-I) expression in porcine granulosa cells in vitro. Using Northern analysis and ribonuclease protection assays with exon-specific probes, we identified the IGF-I messenger RNA (mRNA) transcripts present in these cells under basal and hormone-stimulated conditions. We also assessed changes in secreted IGF-I using Western blots and correlated the change in protein secretion after hormone treatment with changes in mRNA levels. By analogy to the human IGF-I gene and its transcription, two major transcripts of approximately 1 and 7.5 kilobases, seen in freshly isolated granulosa cells and follicle wall and in single passaged granulosa (MDGp1) cells, most likely correspond to IGF-IA. Minor transcripts of 3-4 kilobases, which appeared after FSH or forskolin treatments or in control cells after long exposure of the autoradiographs, were attributed to incompletely processed RNA precursors. Ribonuclease protection assay analysis using probes to detect alternative use of exon 5 or exon 6 indicated that most, if not all, of the transcripts contained only exon 6 sequence (IGF-IA). Both class 1 and class 2 transcripts were identified using exon 1- and exon 2-specific probes, respectively. GH increased steady state levels of IGF-I mRNA 3-fold, FSH increased it approximately 10-fold, and forskolin maximally increased it 12- to 15-fold. Estradiol had no effect alone or in combination with the other treatments. All treatments that increased IGF-I mRNA coordinately increased both class 1 and class 2 transcripts, with the increase in class 1 greater than that in class 2. Multiple forms of IGF-I protein were seen under basal conditions and after hormone treatment. These were identified based on mRNA analysis and biochemical methods as both glycosylated and nonglycosylated IGF-IA prohormone, incompletely processed forms of prohormone, and the mature peptide. Changes in the levels of total protein were similar to the changes in mRNA (GH, 3-fold; FSH and forskolin, 10- to 20-fold). All forms of the protein changed coordinately, suggesting that these hormones had no major effect on the intracellular processing mechanism. IGF-binding protein-3 was able to bind to all IGF-I forms. These data conclusively demonstrate FSH and GH induction of ovarian IGF-I. The porcine granulosa cell culture system used in these studies should be an excellent system for studying the hormonal regulation of IGF-I expression.

In this paper we report the analysis of porcine ovarian granulosa cells for the expression of several known hepatic estrogen hydroxylase RNAs. Of the P450s examined, only CYP 1A1 RNA was detected. Accordingly, the regulation of this mRNA was studied. The RNA for CYP 1A1 was dramatically and completely induced within 2 hours after exposure of immortalized granulosa cells to 3-methyl-cholanthrene (3MC) and expression could be inhibited with 10 microM phorbol myristate acetate. This message was also inducible by 3MC in cultured primary granulosa cells isolated from immature and developing follicles. Dexamethasone increased the relative expression of CYP 1A1 RNA in 3MC treated cells. In the absence of 3MC, the CYP 1A1 message was expressed in cultured granulosa cells from developing but not immature follicles, indicating developmental regulation of this enzyme. Further support for developmental regulation was provided by studies which detected the appearance of CYP 1A1 RNA during growth of ovarian follicles in vivo. This is the first report identifying a specific P450 estrogen hydroxylase RNA in ovarian granulosa cells.

We have recently established an immortalized granulosa cell line as a model system to investigate ovarian function, with particular emphasis on the insulin-like growth factor (IGF) regulatory system. Previous results have shown that these cells express mRNAs for IGF-binding proteins (IGFBPs)-2 to -5. These IGFBPs are also detected by ligand blots. The current work evaluated the regulation by the IGFs and cAMP on the IGFBPs and their mRNAs and compared the findings to that in primary culture. Our results indicate that levels of the IGFBPs are controlled, in part, by expression of the mRNAs. However, evidence for post-transcriptional regulation was also discovered. IGFBP-3 was stimulated by IGF-I, IGFBP-4 by forskolin, and IGFBP-5 by IGF-I. IGFBP-2, -3, and -4 are expressed under basal conditions whereas IGFBP-5 is only detectable after IGF-I induction. An alteration in the biphasic actions of cAMP in this cell line, as compared to primary culture, was evident.

The effects of growth hormone (GH) +/- pregnant mare's serum gonadotropin (PMSG) on levels of insulin-like growth factor (IGF)-I and -II and IGF binding protein (BP)-2 and -3 in serum and follicular fluid (FFI) and on the expression of their mRNA in the ovaries of prepubertal gilts were determined. Steroids in FFI were also quantified. In the first experiment, GH, given for either 20 or 40 days, caused a distinct (threefold, p < 0.05) increase in IGF-I in both serum and FFI with no change in the FFI:serum ratio (0.65). Effects of GH on IGF-II were opposite, with a drop in circulating and FFI levels (p < 0.05). In contrast to data for IGF-I, FFI levels were higher than those in serum for IGF-II (1.42, FFI:serum); IGF-II levels and the ratio fell after GH treatment. GH for either 20 days or 40 days increased serum IGBP-3 to 140% and 250% of control values while decreasing serum IGFBP-2 by 46% and 31%, respectively (p < 0.001). FFI IGFBP-3 was increased to a similar extent by GH (p < 0.005), but IGFBP-2 was not affected. Neither progesterone (P4) nor estradiol (E2) was affected by treatment with GH. However, androstenedione (A4) was decreased by 20-day and 40-day GH treatment relative to the respective controls (p < 0.05). In the second experiment, PMSG resulted in a modest (28%) increase in intrafollicular IGF-I (p < 0.06).(ABSTRACT TRUNCATED AT 250 WORDS)

BEING told that your newborn child is disabled is perhaps the most heartbreaking news that a parent could ever hear. All too often it is made even more difficult to cope with by clumsy health professionals who either blurt the news out without a moment's thought or prefer to avoid the truth at all costs.
