"Extracts from "Clinical evidence": Menopausal symptoms

DefinitionMenopause begins one year after the last menstrual period. Symptoms often begin in the perimenopausal years.Incidence/prevalenceIn the United Kingdom the mean age for the menopause is 50 years 9 months. The median onset of the perimenopause is between 45.5 and 47.5 years. One Scottish survey (of 6096 women aged 45 to 54 years) found that 84% had experienced at least one of the classic menopausal symptoms, with 45% finding one or more symptoms a problem.¹

Interventions

• Beneficial:OestrogensTibolone

• Likely to be beneficial:ProgestogensClonidine

• Unknown effectiveness:Phyto-oestrogensTestosteroneAntidepressants

PrognosisMenopause is a physiological event. Its timing may be genetically determined. Although endocrine changes are permanent, menopausal symptoms such as hot flushes, which are experienced by about 70% of women, usually resolve with time.² However, some symptoms, such as genital atrophy, may remain the same or worsen.AimsTo reduce or prevent menopausal symptoms, and to improve quality of life with minimum adverse effects.OutcomesFrequency and severity of vasomotor, urogenital, and psychological symptoms; quality of life.MethodsClinical Evidence search and appraisal December 1999. We included only randomised controlled trials (RCTs) and systematic reviews that met Clinical Evidence quality criteria.BenefitsVasomotor symptoms: We found no systematic review. We found over 40 RCTs comparing oestrogen versus placebo and various preparations and/or routes against each other. Most found that oestrogen reduced vasomotor symptoms (data from one RCT in 875 women: odds ratio 0.53, 95% confidence interval 0.31 to 0.93).³ Two RCTs found that transdermal oestrogen at a low dose of 25 μg daily reduced severity of vasomotor symptoms compared with placebo.^4,5 Urogenital system: We found one systematic review (search date 1995) and three subsequent RCTs. The review pooled data from six RCTs.⁶ It found that oestrogen improved urogenital symptoms regardless of the route of administration (no figures available). One subsequent RCT (n=136) found that low dose transdermal oestrogen (25 μg daily) combined with norethisterone acetate significantly reduced vaginal dryness and dyspareunia compared with placebo over six months.⁴ Two other RCTs (n=192) found that local administration of oestrogen using a silicone oestradiol releasing vaginal ring over 24-36 weeks improved vaginal oestrogenisation and pH compared with placebo.^7,8 One of these trials also found a significant reduction in incidence of urinary tract infection in treated women (P=0.008).⁷ Psychological symptoms: We found one systematic review (search date 1995, 14 RCTs, 12 cohort studies), which found that oestrogen reduced depressed mood among menopausal women.⁹ Duration of treatment ranged from one month to two years. Data pooling for oestrogen versus placebo (10 studies) found that oestrogen reduced depressive symptoms (no figures available). We found no RCTs of oestrogen treatment in women with clinically proved depression. We found one systematic review (search date 1996, 10 controlled trials, 9 observational studies) of the effects of oestrogen on cognitive function in postmenopausal women and women with Alzheimer''s disease.¹⁰ Studies were too weak to allow reliable conclusions. An additional crossover RCT (n=62) found a beneficial effect of oestrogen on sleep quality compared with placebo over seven months.¹¹ Quality of life: We found no systematic review. We found four RCTs (639 women, 3 RCTs placebo controlled, 3 versus progestogen), which found significant improvement in quality of life in women treated with oestrogen compared with baseline or placebo.^12–15 The largest RCT (242 women) found that oestrogen improved quality of life (P=0.0003) and wellbeing (P=0.003) compared with placebo over 12 weeks.¹²HarmsMany RCTs have found that oestrogen causes weight gain and breast tenderness in the short term. Although many women report an increase in weight when starting oestrogen, we found no evidence from RCTs that oestrogen causes significant weight gain in the long term. The most important long term adverse effects are increased risk of venous thromboembolic disease, endometrial cancer, and breast cancer.^16–18 The relation between oestrogen (as hormone replacement therapy) and breast cancer was reviewed in a reanalysis of 51 studies of more than 160 000 women.¹⁹ The review found that the risk of breast cancer increased by 2.3% (1.1% to 3.6%) each year in women using hormone replacement therapy. Five or more years after hormone replacement therapy was stopped, there was no significant excess of breast cancer.¹⁹CommentMany studies used selected populations such as women attending hospital clinics, who may be different in their behaviour, personality, and symptom profile to women of the same age seen in primary care or those who do not seek medical advice. Option: ProgestogensSummary We found good evidence from RCTs that progestogens reduce vasomotor symptoms. We found no good quality evidence on other outcomes, including quality of life.BenefitsWe found no systematic review. Vasomotor symptoms: We found five RCTs (257 women, all trials less than a year long), which found that women taking progestogens experienced a significant reduction in vasomotor symptoms compared with placebo.^20–24 The single RCT comparing oestrogen alone with progestogen (150 mg of depot medroxyprogesterone for 25 days a month) found that over three months, 18% of women taking oestrogens and 33% taking progestogen reported no vasomotor symptoms.²¹ One RCT (n=102) found that transdermal progesterone cream 20 mg daily improved vasomotor symptoms compared with placebo (P<0.001) but had no beneficial effect on bone density.²⁵ Urogenital system: We found no RCTs evaluating the effects of progestogens alone on urinary incontinence, the lower genital tract, or sex life. Psychological symptoms: We found no RCTs. Quality of life: One RCT of cyclical progestogen plus oestrogen for six months found no evidence of an effect on quality of life.²⁶ We found no studies of progestogen alone on quality of life.HarmsWe found two RCTs that evaluated harms of progestogens. The first compared continuous progestogen (norgestrel) and placebo in 321 women who had undergone hysterectomy and were already taking conjugated oestrogen. It found no difference in symptoms (including weight gain and bloating).²⁷ The second RCT (875 women) compared various oestrogen-progestogen combinations over three years.³ It found that additional progestogen increased breast discomfort (odds ratio 1.92, 1.16 to 3.09). Neither trial found evidence of an effect on cardiovascular events.CommentProgestogen is seldom given alone, which makes it hard to isolate its effects. When it was given without oestrogen, doses of progestogens were high, the lowest dose being 20 mg medroxyprogesterone acetate per day. Option: TiboloneSummary RCTs found that tibolone significantly improved vasomotor symptoms, libido, and vaginal lubrication.BenefitsWe found no systematic review. Vasomotor symptoms: We found three RCTs, two of tibolone versus continuous combined oestrogen/progestogen treatment over 48 and 52 weeks (672 women with menopausal symptoms)^28,29 and one versus placebo over 16 weeks (82 women with menopausal symptoms).³⁰ The first RCT found a slightly greater reduction in hot flushes with the combined regimen than with tibolone over 48 weeks (P=0.01). The second trial found a significant reduction in vasomotor symptoms from baseline in both groups (67/72 women on HRT and 58/68 women on tibolone, P<0.001) but no significant difference between groups. The third trial found tibolone reduced vasomotor symptoms by 39% compared with placebo (P=0.001). Urogenital system: We found two RCTs. The first RCT found no significant difference between tibolone and combined hormonal treatment in terms of subjective reports of vaginal lubrication; both interventions improved lubrication compared with baseline.²⁸ The second RCT (437 women) found that tibolone improved sexual satisfaction compared with oestradiol plus norethisterone (P<0.05).³¹ We found no RCTs examining effects on urinary incontinence. Psychological symptoms: We found no RCTs. Quality of life: We found no RCTs. Bone density: We found nine RCTs, which found that tibolone increased bone density over periods from 6 to 36 months compared with baseline or placebo.³²HarmsWe found no evidence on adverse effects from RCTs. One non-randomised controlled trial found that the main unwanted effect of tibolone was breakthrough bleeding, which occurred in about 10% of users.³³ We found no good evidence of androgenic adverse effects such as hair growth and greasiness of the skin. Two RCTs of short term use found a 33% reduction in plasma high density lipoproteins with tibolone,^34,35 although the long term effects on cardiovascular disease are unknown.CommentNone. Option: Phyto-oestrogensSummary Limited evidence from small RCTs suggests that soy flour, which contains phyto-oestrogens, may relieve vasomotor menopausal symptoms.BenefitsWe found no systematic review. Vasomotor symptoms: We found three placebo controlled RCTs. Two evaluated soy supplements, which contain phyto-oestrogen, using double blind designs; the other, which was not blinded, evaluated isoflavone. The first RCT (58 postmenopausal women) compared soy flour versus wheat flour for 12 weeks and found that hot flushes were reduced significantly more in the group of women using soy flour (40% v 25% reduction).³⁶ The second RCT used a crossover design to evaluate six weeks'' administration of 34 mg soy protein daily. It found reduced severity but not frequency of vasomotor symptoms.³⁷ The third RCT (n=51) used a crossover design to compare isoflavone 40 mg daily with placebo. It found benefit from placebo compared with baseline, but not with isoflavone.³⁸ Urogenital system: We found no RCTs. Psychological symptoms: We found no RCTs. Beneficial effects of treatment on quality of life: We found no RCTs.HarmsWe found no evidence of significant adverse effects.CommentNone. Option: ClonidineSummary Two RCTs found that clonidine reduced vasomotor symptoms.BenefitsWe found no systematic review. Vasomotor symptoms: We found two RCTs.^39,40 One crossover RCT (66 women) found that clonidine reduced the mean number of flushing attacks in the 14 days after crossover compared with placebo (56.8 v 64.3, P<0.05).³⁰ The second RCT (30 women) found that more women taking clonidine reported reduced flushes at 8 weeks (12/15 v 5/14, P<0.04).⁴⁰ Psychological symptoms: We found no RCTs. Quality of life: We found no RCTs.HarmsThe two RCTs found no significant difference in the incidence of unwanted effects between placebo and active treatment groups.^39,40CommentNone. Option: TestosteroneSummary We found evidence from RCTs that testosterone improves sexual enjoyment and libido. We found no studies evaluating effects on other commonly experienced menopausal symptoms.BenefitsWe found no systematic review. Vasomotor symptoms: We found no RCTs evaluating testosterone alone in women with menopausal symptoms. We found one RCT (93 postmenopausal women) comparing oestrogen alone and oestrogen plus methyltestosterone. This concluded that addition of a small dose of methyltestosterone reduced the dose of oestrogen needed to control menopausal symptoms.⁴¹ Urogenital system: We found two RCTs, one in 40 women and one crossover study in 53 women. Both found benefit from exogenous testosterone on self reported sexual enjoyment, desire, and arousal.^42,43 Psychological symptoms: We found no RCTs. Beneficial effects of therapy on quality of life: We found no RCTs.HarmsWe found no evidence from RCTs or other controlled studies on the incidence of androgenic adverse effects with testosterone.CommentNone. Option: AntidepressantsSummary We found insufficient evidence on the effects of antidepressants on menopausal symptoms.BenefitsWe found no systematic review or RCTs that specifically addressed the effects of antidepressants on menopausal symptoms or quality of life in menopausal women.HarmsWe found no evidence on adverse effects in postmenopausal women. Antidepressants as a group can cause many central nervous system adverse effects, including sedation and agitation, as well as urinary and vision problems, liver dysfunction, and cardiac dysrhythmias.⁴⁴CommentNone.     

Orienting reflex: "targeting reaction" and "searchlight of attention"

The concept of orienting reflex based on the principle of vector coding of cognitive and executive processes is proposed. The orienting reflex to non-signal and signal stimuli is a set of orienting reactions: motor, autonomic, neuronal, and subjective emphasizing new and significant stimuli. Two basic mechanisms can be identified within the orienting reflex: a "targeting reaction" and a "searchlight of attention". In the visual system the first one consists in a foveation of a target stimulus. The foveation is performed with participation of premotor neurons excited by saccadic command neurons of the superior colliculi. The "searchlight of attention" is based on the resonance of gamma-oscillations in the reticular thalamus selectively enhancing responses of cortical neurons (involuntary attention). The novelty signal is generated in novelty neurons of the hippocampus, which are selectively tuned to a repeatedly presented standard stimulus. The selective tuning is caused by the depression of plastic synapses representing a "neuronal model" of the standard stimulus. A mismatch of the novel stimulus with the established neuronal model gives rise to a "novelty signal" enhancing the novel input. The novelty signal inhibits current conditioned reflexes (external inhibition) contributing to redirecting the behavior. By triggering the expression of early genes the novelty signal initiates the formation of the long-term memory connected with neoneurogenesis.     

Chinchilla "big" and "little" gastrins

Gastrin heptadecapeptides (gastrins I and II which differ in the presence of sulfate on the tyrosine of the latter) have been purified and sequenced from several mammalian species including pig, dog, cat, sheep, cow, human and rat. A 34 amino acid precursor ("big" gastrin), generally accounting for only 5% of total gastrin immunoreactivity, has been purified and sequenced only from the pig, human, dog and goat. Recently we have demonstrated that guinea pig (GP) "little" gastrin is a hexadecapeptide due to a deletion of a glutamic acid in the region 6-9 from its NH2-terminus and that GP "big" gastrin is a 33 amino acid peptide. The chinchilla, like the GP, is a New World hystricomorph. This report describes the extraction and purification of "little" and "big" gastrins from 31 chinchilla antra. Chinchilla "little" gastrin is a hexadecapeptide with a sequence identical to that of the GP and its "big" gastrin is a 33 amino acid peptide with the following sequence: (See text)

"Natural" progesterone: information on fetal effects

BACKGROUND: A variety of progestational agents have been used therapeutically and evaluated for adverse effects over the last 50 years. However, progesterone itself has come into use as a therapeutic agent only recently with the development of an orally bioavailable "micronized" preparation. METHODS: The current review examines progesterone adverse effects as identified in the larger literature on the toxicity of progestational agents and pharmacokinetics. RESULTS: Progesterone has cytoplasmic and membrane receptors in a variety of reproductive and nonreproductive tissues including the brain and is a potent inhibitor of GnRH. Limited information is available on progesterone receptors and actions in the fetus. Concern about exogenous progestagen effects on fetal reproductive tract development have led to considerable human research over the years, but this literature review demonstrates that contemporary developmental toxicology research on progesterone is lacking. CONCLUSIONS: Progesterone is a potent, multi-faceted endocrine agent with an expanding therapeutic profile and a minimal scientific database for evaluating safe use during pregnancy.

Motile plant cell body: a "bug" within a "cage"

Analysis of the cytoskeleton in morphogenetically active plant cells allows us to propose a unified concept for the structural organization of eukaryotic cells. Their cytoarchitecture is determined by two principal structural complexes: nucleus-microtubule-based cell bodies ("bugs") and plasma-membrane-F-actin-based cell periphery complexes ("cages"). There are dynamic interactions between each of these entities in response to extracellular and intracellular signals. In the case of the cell body, these signals determine its polarization, rotation and migration. Interactions between cell body and cell periphery complexes determine cell growth polarity and morphogenesis throughout the eukaryotic kingdom.

Opossum (Didelphis virginiana) "little" and "big" gastrins

1. "Little" gastrins from most mammalian species are 17 amino acid peptides and the precursor "big" gastrins are 34 amino acid peptides. 2. "Little" gastrins of the New World hystricomorphs, guinea-pig and chinchilla, are 16 amino acid peptides due to deletion of a glutamic acid in the region 6-9 from their NH2-terminus and the corresponding "big" gastrins are 33 amino acid peptides. 3. Antral gastrins from the opossum, a New World marsupial, have a glutamic acid deletion in the same region as the hystricomorph gastrins. 4. Opossum "big" gastrin is a 33 amino acid peptide with the following sequence: less than ELGPQDLPYLTADLSKKQGPWLEEEEAYGWMDF#.     

Proteolytic Digestion Patterns of "Soluble"and "Detergent-Soluble"Bovine Caudate Nucleus Acetylcholinesterases

Abstract: The structures of purified "soluble"and "detergent-soluble"bovine caudate nucleus acetylcholinesterases were compared by peptide mapping on polyacrylamide gels. The digestion products generated from the two acetylcholinesterases on proteolysis by a given protease ( Staphylococcus aureus V8 protease, α-chymotrypsin, or papain) are remarkably similar as judged from the electrophoretic band patterns. We conclude that the "soluble"and "detergent-soluble"acetylcholinesterases from bovine caudate nucleus share a common evolutionary origin.     

The use of multifolded pericranial flaps as "plugs" and "pads"

Pericranial flaps are thin and, hence, their volumes are small. Therefore, their use for soft-tissue augmentation has not been popular. In this article, the author introduces a new concept: the use of a multifolded pericranial flap as a "plug" or a "pad" for localized contour defects. Eight patients were included in the study. In all cases, an anteriorly based pericranial flap was used, and the flap was folded on itself several times to increase its bulk. The results were satisfactory in all patients. The literature on the topic is reviewed, and the blood supply of pericranial flaps is discussed.     

Weighting improves the "new Haseman-Elston" method

Elston et al. [Genet Epidemiol, in press] apply the results of Wright [Am J Hum Genet 1997;60:740-742] and Drigalenko [Am J Hum Genet 1998;63:1242-1245] to extend the traditional Haseman-Elston regression scheme [Haseman and Elston, Behav Genet 1972;2:3-19] to include not only linkage information contained in the sib pair's squared difference, but also information in their mean-corrected squared sum. The new algorithm detects linkage to a quantitative trait locus by modelling sib pair trait covariance as a function of identity-by-descent status. We demonstrate why this new estimator is suboptimal and can in some cases be inferior to the original Haseman-Elston method. We also describe a simple approach to estimation which improves on this new Haseman-Elston method by incorporating variance-based weights into the test statistic while staying within the linear modelling framework. In support of our theoretical claim, we conduct both a sib pair simulation and an application to GAW 10 sib pair data showing that our new estimator is superior to both the old and new Haseman-Elston schemes currently implemented in the analysis package S.A.G.E. 4.0.     

Aspects of eating behaviors "disinhibition" and "restraint" are related to weight gain and BMI in women

Objective: The causes of adult weight gain leading to obesity are uncertain. We examined the association of adult weight gain and obesity with subscales of eating behavior characteristics in older women. Methods and Procedures: Current height and weight, eating behavior subscales (disinhibition subscales—habitual, situational, and emotional; restraint subscales—flexible and rigid; hunger subscales—internal and external) as assessed using the Eating Inventory (EI), and self‐reported body weight at six prior age intervals were reported by 535 women aged 55–65 years. Multiple regression analysis was used to examine the relationships between EI subscale scores and weight change from the age interval of 30–39 to 55–60 years and current BMI. Results: The strongest correlate of weight gain over 20 years was susceptibility to overeating in response to everyday cues within the environment (habitual disinhibition; partial correlation coefficient (r) = 0.25, P < 0.001); susceptibility to overeating in response to emotional states such as depression (emotional disinhibition) was a quantitatively weaker but significant correlate (partial r = 0.17, P < 0.001), and susceptibility to overeating in response to specific situations such as social occasions (situational disinhibition) was not associated with weight gain. Flexible control of dietary restraint attenuated the influence of habitual disinhibition in particular on weight gain and BMI, and was less effective in attenuating associations of emotional or situational disinhibition. Discussion: Lifestyle modification programs for prevention and treatment of adult‐onset obesity currently focus on reducing situational and emotional overeating; the results of this study suggest that a stronger emphasis on strategies that target habitual overeating may be warranted.     

Characteristics of activity of "fast" and "slow" Purkinje cells of the cerebellum

In the guinea pig cerebellar cortex, three types of Purkinje cells were identified according to the properties of complex spikes: fast, intermediate, and slow cells. Fast Purkinje cells have following properties as compared with slow Purkinje cells: (i) salient components with short intervals in complex impulses (on the average, five components with a period of about 2 ms versus two components with a period of about 4 ms); (ii) a short duration of simple spikes (in the average, 2.13 +/- 0.53 ms versus 3.9 +/- 0.65 ms) and a quick restoration of their amplitude after preceding simple spikes (in the mean, 2.83 +/- 0.75 ms versus 11.0 +/- 2.82 ms); and (iii) a more pronounced rebound in the auto-correlation histogram of simple spikes (3.09 +/- 2.12 versus 1.45 +/- 0.36) and a short-latency excitation of simple spikes after complex spikes (2.81 +/- 1.64 versus 1.26 +/- 0.52). A decrease of interspike intervals in simple spike activity of all Purkinje cells was revealed (5.25 +/- 2.71 ms versus 9.71 +/- 3.48 ms in activity fragments without complex spikes). It is supposed that the properties of complex spikes depend on the type of Purkinje cells and may be one of the basic factors determining the interactions between the inputs of climbing and parallel fibers in Purkinje cells.     

Situational Designations in "Glossoethnographic" Perspective

Soviet and foreign linguists and educators continually stress the importance of studying a foreign language within its cultural context. Accordingly, a new field of applied linguistics has emerged, at the borderline between linguistics and foreign language instruction, that we have termed "glossoethnography" [see 1, 2, 4, 61. This new area of linguistics has not yet sufficiently delimited i t s subject matter: it abuts on other areas that are also relatively new and as yet ill defined, such as sociolinguistics, ethnolinguistics, linguistic anthropology, linguistic typology (for the various definitions of these disciplines, see reference 7). The many interesting examples adduced in studies in this new area all deal with specific national features of linguistic means of expression (sometimes in combination with paralinguistic means). However, these specific features exist on different levels: there are the specific features of the real objects expressed in language, and then there are those of the linguistic forms themselves, which are independent of the properties of the real objects to which they refer.

"Craziness" and "visions": experiences after a stroke.

For a stroke victim there may be at least three types of strange occurrences: incorrect saying, seeing, and thinking. To the patient only the third seems to be "crazy". After a stroke (left hemisphere), which mainly produced serious aphasia, I (the patient) felt crazy two or three times when someone said something I expected him to say. On the other hand, my initial aphasic "gibberish speech" and an occasional false vision did not seem crazy. In my case the vision is always a car or a child, seen on my extreme right, where I am otherwise blind from the stroke. I am always driving when it happens; in recent years this phenomenon occurs when I am tired or tense, or the light is poor. These rapid visions do not seem insane but merely physical problems in my eyes, much like ordinary people''s dreams.
